Cutibacterium (Propionibacterium) acnes , a gram-positive bacillus with low pathogenicity, is an uncommon but known cause of prosthetic joint infections, particularly related to shoulder surgery. C. acnes , however, is an extremely rare pathogen in the nonoperated knee joint. This report details an uncommon case of C. acnes septic knee arthritis after multiple intra-articular steroid injections in a 56-year-old male patient. After an indolent presentation and late diagnosis, the patient underwent surgical debridement with IV antibiotic management. This case illustrates that intra-articular corticosteroid injections for the management of osteoarthritis are not without risk. Literature supporting their use remains limited and clinicians should use proficient clinical judgment for appropriate patient selection for these injections. Vigilance following injections or aspirations of the knee should be maintained to identify the indolent clinical presentation of C. acnes septic arthritis. PMID:28825032

We present a 45-year-old patient who had acute radial nerve palsy following a blunt trauma without any fracture or dislocation. He was injured by strucking in a combat three months ago. The patient has been followed by application of a long-arm plaster cast before referred to our clinic. Preoperative electromyoneurography and magnetic resonance imaging (MRI) indicated that there was a radial nerve injury on humeral groove. The British Medical Research Council (MRC) grade was 2/5 on his wrist preoperatively. The patient underwent an operation under general anesthesia. It was seen to be a second-degree nerve injury. The patient has subsequently regained full movement on his wrist and finger extension in six months. We suggest that a detailed clinical and electrodiagnostical evaluation is necessary in patients who have radial nerve injury when deciding the treatment, conservative or surgical. PMID:22347334

To describe a technique of endoscopic medial maxillectomy with mucosal flap for postoperative maxillary sinus mucoceles and to present a case series of subjects who underwent this procedure. This case series includes four subjects with postoperative maxillary sinus mucoceles who underwent resection via endoscopic partial medial maxillectomy with a mucosal flap. We will discuss the clinical presentation, imaging characteristics, operative details, and outcomes. Four subjects are included in this study. The average age at the time of medial maxillectomy was 52 years (range 35-65 years). Three subjects (75%) were female. One subject (25%) had bilateral postoperative maxillary sinus mucoceles. Two subjects (50%) had unilateral right sided mucoceles, and the remaining subject had a unilateral left sided mucocele. All subjects had a history of multiple sinus procedures for chronic sinusitis including Caldwell-Luc procedures ipsilateral to the postoperative mucocele. All subjects underwent endoscopic medial maxillectomy without complication and were symptom free at the last follow up appointment, average 24 months (range 3-71 months) after medial maxillectomy. For postoperative maxillary sinus mucoceles in locations that are difficult to access via the middle meatus antrostomy, we recommend endoscopic medial maxillectomy with mucosal flap. Our preliminary experience with four subjects demonstrates complete resolution of symptoms after this procedure. Copyright © 2014 Elsevier Inc. All rights reserved.

Background Functional gonadotroph adenomas (FGA) are rare tumors of the pituitary gland that secrete biologically active gonadotropins. Objective To advance clinical understanding of FGA. Methods We performed a retrospective review of adult patients who underwent resection of a pituitary lesion between August 1997 and October 2014 and remain under care at our center. We identified patients who had pathologic and biochemical confirmation of FGA, as defined by lack of serum LH/FSH suppression in the setting of elevated gonadal steroids, associated clinical symptoms, or both. Results FGA was documented in seven patients (five men, two women) over a 17-year period. Clinical findings at presentation included visual field deficits in five patients, headache in three, sexual dysfunction in three, and ovarian cysts in both women. Each patient underwent lesional resection (six by the endonasal transsphenoidal approach, one by craniotomy with transsphenoidal reoperation). Analysis of tumor samples revealed immunopositivity for FSH/LH in five patients and FSH only in two patients. Post-operative follow-up (median 10 mo, range 4-213 mo) indicated remission in six of seven patients. Conclusion FGA can pose both a diagnostic and therapeutic challenge. The tumor is often diagnosed as a nonfunctioning macroadenoma after presenting with non-specific symptoms, and is the cause of significant morbidity. FGA should be considered in the differential diagnosis of patients harboring pituitary adenomas with reproductive dysfunction. Transsphenoidal resection is the initial treatment of choice, and can reduce endocrine dysfunction, resolve headaches, improve visual impairment, and provide tissue for detailed analysis.

Objective The study aimed to describe portal stenting for postoperative portal occlusion with delayed (≥ 3 months) variceal bleeding in the afferent jejunal loop. Materials and Methods Eleven consecutive patients (age range, 2–79 years; eight men and three women) who underwent portal stenting between April 2009 and December 2015 were included in the study. Preoperative medical history and the postoperative clinical course were reviewed. Characteristics of portal occlusion and details of procedures were also investigated. Technical success, treatment efficacy (defined as disappearance of jejunal varix on follow-up CT), and clinical success were analyzed. Primary stent patency rate was plotted using the Kaplan-Meier method. Results All patients underwent hepatobiliary-pancreatic cancer surgery except two children with liver transplantation for biliary atresia. Portal occlusion was caused by benign postoperative change (n = 6) and local tumor recurrence (n = 5). Variceal bleeding occurred at 27 months (4 to 72 months) and portal stenting was performed at 37 months (4 to 121 months), on average, postoperatively. Technical success, treatment efficacy, and clinical success rates were 90.9, 100, and 81.8%, respectively. The primary patency rate of portal stent was 88.9% during the mean follow-up period of 9 months. Neither procedure-related complication nor mortality occurred. Conclusion Interventional portal stenting is an effective treatment for delayed jejunal variceal bleeding due to portal occlusion after hepatobiliary-pancreatic surgery. PMID:28860900

Unusual symptoms such as digit misidentification and neglect-like phenomena have been reported in complex regional pain syndrome (CRPS), which we hypothesized could be explained by parietal lobe dysfunction. Twenty-two patients with chronic CRPS attending an in-patient rehabilitation programme underwent standard neurological examination followed by clinical assessment of parietal lobe function and detailed sensory testing. Fifteen (68%) patients had evidence of parietal lobe dysfunction. Six (27%) subjects failed six or more test categories and demonstrated new clinical signs consistent with their parietal testing impairments, which were impacting significantly on activities of daily living. A higher incidence was noted in subjects with >1 limb involvement, CRPS affecting the dominant side and in left-handed subjects. Eighteen patients (82%) had mechanical allodynia covering 3-57.5% of the body surface area. Allochiria (unilateral tactile stimulation perceived only in the analogous location on the opposite limb), sensory extinction (concurrent bilateral tactile stimulation perceived only in one limb), referred sensations (unilateral tactile stimulation perceived concurrently in another discrete body area) and dysynchiria (unilateral non-noxious tactile stimulation perceived bilaterally as noxious) were present in some patients. Greater extent of body surface allodynia was correlated with worse parietal function (Spearman's rho = -0.674, p = 0.001). In patients with chronic CRPS, detailed clinical examination may reveal parietal dysfunction, with severity relating to the extent of allodynia. © 2012 European Federation of International Association for the Study of Pain Chapters.

To conduct a validation study of 123 I-N-fluoropropyl-2b-carbomethoxy-3b-(4-iodophenyl) nortropane ( 123 I-FP-CIT) SPECT dopaminergic imaging in the clinical diagnosis of dementia with Lewy bodies (DLB) with autopsy as the gold standard. Patients >60 years of age with dementia who had undergone 123 I-FP-CIT imaging in research studies and who had donated their brain tissue to the Newcastle Brain Tissue Resource were included. All had structured clinical research assessments, and clinical diagnoses were applied by consensus panels using international diagnostic criteria. All underwent 123 I-FP-CIT imaging at baseline, and scans were rated as normal or abnormal by blinded raters. Patients were reviewed in prospective studies and after death underwent detailed autopsy assessment, and neuropathologic diagnoses were applied with the use of standard international criteria. Fifty-five patients (33 with DLB and 22 with Alzheimer disease) were included. Against autopsy diagnosis, 123 I-FP-CIT had a balanced diagnostic accuracy of 86% (sensitivity 80%, specificity 92%) compared with clinical diagnosis, which had an accuracy of 79% (sensitivity 87%, specificity 72%). Among patients with DLB, 10% (3 patients) met pathologic criteria for Lewy body disease but had normal 123 I-FP-CIT imaging. This large autopsy analysis of 123 I-FP-CIT imaging in dementia demonstrates that it is a valid and accurate biomarker for DLB, and the high specificity compared with clinical diagnosis (20% higher) is clinically important. The results need to be replicated with patients recruited from a wider range of settings, including movement disorder clinics and general practice. While an abnormal 123 I-FP-CIT scan strongly supports Lewy body disease, a normal scan does not exclude DLB with minimal brainstem involvement. This study provides Class I evidence that 123 I-FP-CIT dopaminergic neuroimaging accurately identifies patients with DLB. Copyright © 2016 The Author(s).

To report the clinical features, management, and outcome of 7 cases of culture-proven multidrug-resistant Enterobacter postoperative endophthalmitis following cataract surgery. Medical records of 7 cases of acute postoperative endophthalmitis after uneventful cataract surgery were reviewed. Details regarding age, gender, visual acuity and clinical features at presentation, microbiological profile, treatment interventions, and visual acuity and clinical features at 1 week, 1 month, and 3 months follow-up were collected. All patients reported decreased visual acuity and pain as presenting symptoms. All patients were resistant to intravitreal antibiotics such as vancomycin (1 mg/0.1 mL) and ceftazidime (2.25 mg/0.1 mL). Culture of aqueous and vitreous sample was positive for Enterobacter aerogenes and sensitive to co-trimoxazole, cefoperazone-sulbactam, imipenem-meropenem, and piperacillin-tazobactem. Two patients with panophthalmitis and no perception of light underwent evisceration. Three patients had visual acuity of ≥6/24 at the final follow-up. Multidrug-resistant Enterobacter acute postoperative endophthalmitis has a poor prognosis if not intercepted early.

To describe an unusual series of complications after glaucoma filtering surgeries with their clinical findings and outcome after tailored non-conventional modes of therapy. Eighteen patients who underwent re-interventions (medical or surgical) after glaucoma filtering surgeries during the period at two tertiary centers, excluding those that required conventional modes of treatment (medical control or re-trabeculectomy, simple wound closure for traumatic wound dehiscence, bleb revision or needling, laser iridotomy), were included. Relevant clinical details with intraoperative videos, intraoperative or postoperative problems, and images with course after re-intervention were retrieved from the hospital database. Clinical details which helped in clinching diagnosis and cause for problems and course after intervention with final vision and intraocular pressure were evaluated. Six of 18 eyes required surgical management for an unusual course of events after an uneventful filtering surgery. Bleb morphology and close follow-up of the conjunctiva, in addition to intraocular pressure (IOP) and anterior chamber (AC) configuration, helped diagnose possible aetiology and appropriate tailored management. All patients had good IOP and visual outcome in all except one with macular scar status after retinal detachment surgery. Assessment of the bleb morphology in the postoperative course coupled with monitoring of the conjunctival wound are essential to conventional monitoring of IOP and anterior chamber configuration to arrive at appropriate management for rare unusual events after glaucoma surgery.

Background and aims: Barrett’s esophagus (BE) and colorectal neoplasms share similar risk factors. Previous studies have shown variable prevalence of colon polyps in patients with BE. Our aims were to determine the prevalence and incidence of colon polyps in patients with BE, compared to those without BE. Methods: In this case-control study, the study group included patients, aged 50–75 years, with biopsy-proven BE, who underwent colonoscopy at Cleveland Clinic from January 2002 to December 2011. The control group consisted of age- and sex-matched patients who underwent colonoscopy and also an endoscopy with no evidence of BE during the same time period. Exclusion criteria for both groups were family- or personal previous history of colon cancer or polyps, prior colonic resection, inflammatory bowel disease and familial polyposis syndromes. Patient demographics, comorbidities, medication use and endoscopic and colonoscopic details were collected, including biopsy results. Results: A total of 519 patients were included in the study; 173 patients with BE in the study group and 346 without BE in the control group. Mean age at index colonoscopy was 61 ± 8 years and 75% of patients were male. On index colonoscopy, patients with BE were more likely to have polyps than controls (45% vs 32%, respectively; P = 0.003). Patients underwent between one and five colonoscopies during the follow-up. On multivariate analysis—after adjusting for age, gender and diabetes—patients with BE were 80% more likely to have any type of polyp, and 50% more likely to have adenomas found during colonoscopy. Conclusions: Patients with BE had higher prevalence and incidence of colon polyps. This has important clinical implications for screening and surveillance in BE patients. PMID:25085954

Natural air leak test without submergence for spontaneous pneumothorax.

Uramoto, Hidetaka; Tanaka, Fumihiro

2011-12-24

Postoperative air leaks are frequent complications after surgery for a spontaneous pneumothorax (SP). We herein describe a new method to test for air leaks by using a transparent film and thoracic tube in a closed system. Between 2005 and 2010, 35 patients underwent a novel method for evaluating air leaks without submergence, and their clinical records were retrospectively reviewed. The data on patient characteristics, surgical details, and perioperative outcomes were analyzed. The differences in the clinical background and intraoperative factors did not reach a statistically significant level between the new and classical methods. The incidence of recurrence was also equivalent to the standard method. However, the length of the operation and drainage periods were significantly shorter in patients evaluated using the new method than the conventional method. Further, no postoperative complications were observed in patients evaluated using the new method. This simple technique is satisfactorily effective and does not result in any complications.

Psychological and psychosexual aspects of vulvar vestibulitis.

AIMS: To objectively assess the psychological and psychosexual morbidity of patients with vulvar vestibulitis. METHODS: 30 patients with variable degrees of vulvar vestibulitis were recruited from a vulval clinic. Each patient underwent a detailed history and clinical examination. Friedrich's criteria were used for the diagnosis of vulvar vestibulitis. Standardised questionnaires to assess psychological and psychosexual function were completed by the patient before review. These questionnaires were the STAI and a modified psychosexual questionnaire introduced by Campion. RESULTS: Patients experienced considerable psychological dysfunction compared with controls. All aspects of psychosexual dysfunction were affected. CONCLUSIONS: When managing patients, psychosexual and psychological issues must be considered in addition to other conventional types of therapy. Vulvar vestibulitis may be a risk factor for developing psychosexual complications including vaginismus, low libido, and orgasmic dysfunction. Consideration of these factors must be an integral part of the management of patients with all chronic vulval conditions. PMID:9582478

Sixty-six feet (62 patients) with displaced intra-articular calcaneal fractures underwent manual reduction and distraction with the use of a triangular tube-to-bar external fixation device and were retrospectively reviewed at a minimum of 1-year post-operative. Final radiographic follow-up revealed complete consolidation in all fractures, maintenance of reduction, and limited degenerative osteoarthrosis about the subtalar joint. Our results indicate that with proper application and attention to detail, restoration of calcaneal morphology using triangular tube-to-bar external fixation should be considered a viable alternative in the treatment of displaced intra-articular fractures of the calcaneus.

Recent literature has questioned the efficacy of routine detailed preoperative cardiac ischemia testing and preoperative cardiac intervention before noncardiac surgical procedures. We performed a retrospective review of patients undergoing thoracotomy (n = 294) between January of 1999 and January of 2005. The median age was 62 years. Detailed preoperative cardiac testing was performed on 184 patients (63%) and went beyond a thorough history, physical examination, and electrocardiogram to include at least one of the following: dobutamine stress echo (n = 116), nuclear stress test (n = 66), treadmill test (n = 8), and coronary angiogram (n = 40). Evidence for coronary disease was detected in 43% of tests (99/230) performed. Revascularization was performed in 10% of all patients (4/40) who underwent coronary angiography. Postoperative myocardial infarction occurred in 7 patients (2.4%) with 4 myocardial infarction-related mortalities. No significant difference was found in the incidence of myocardial infarction in patients with (n = 184) or without (n = 110) detailed preoperative cardiac testing (3.3% vs 0.9%, P = .29). Of the 4 patients (1.4%) who underwent revascularization to treat coronary lesions identified during prethoracotomy workup, 2 had a myocardial infarction, 1 of which was caused by thrombosis of a coronary stent. In the subset of patients who underwent lobectomy (n = 149), detailed cardiac testing was performed on 107 patients (72%). The incidence of myocardial infarction was similar in tested and untested patients (2.8% vs 2.4% respectively, P = 1.0). Selective use of detailed preoperative cardiac testing refines risk stratification and identifies patients for corrective cardiac interventions; however, it did not prove fully protective against myocardial infarction after thoracotomy in our study.

Laparoscopic sleeve gastrectomy is a safe and effective bariatric operation, but postoperative reflux symptoms can sometimes necessitate revisional surgery. Roux-en-Y gastric bypass is the preferred operation in morbidly obese patients with gastro-oesophageal reflux disease. In 2011, we introduced preoperative endoscopy to assess for hiatus hernia or evidence of oesophagitis in conjunction with an assessment of gastro-oesophageal reflux symptoms for all patients undergoing bariatric surgery with a view to avoid sleeve gastrectomy for these patients. A prospectively maintained database was used to identify patients who underwent sleeve gastrectomy before and after we changed the unit policy. The need for revisional surgery in patients with troublesome gastro-oesophageal reflux disease was examined. Prior to 2011, 130 patients underwent sleeve gastrectomy, and 11 (8.5%) of them required conversion to Roux-en-Y gastric bypass for symptomatic reflux disease. Following the policy change, 284 patients underwent sleeve gastrectomy, and to date, only five (1.8%) have required revisional surgery (p = 0.001). Baseline demographics were comparable between the groups, and average follow-up period was 47 and 33 months, respectively, for each group. Preoperative endoscopy and a detailed clinical history regarding gastro-oesophageal reflux symptoms may improve patient selection for sleeve gastrectomy. Avoiding sleeve gastrectomy in patients with reflux disease and/or hiatus hernia may reduce the incidence of revisional surgery. © 2016 World Obesity.

It is remained unknown that the flow characteristics changes between pre- and post-operative severe carotid artery stenosis could affect the long-term patency or failure. However, in-vivo clinical experiments to uncover the flow details are far from bed-side due to limited measurement resolutions, blurring artifact, etc. We studied detailed flow characteristics of more than 75% severe carotid artery stenosis before and after surgical treatments. Real-size flow phantoms for 10 patients, who underwent carotid endarterectomy with patch/no patch closure, were prepared by using a 3D rapid-prototype machine from CT scanned images. The working fluid is a glycerin aqueous solution, and patient-specific pulsatile flows were applied to the phantoms, based on ultrasonic flow rate measurements. The flows were visualized with magnetic resonance velocimetry (MRV). The detailed flow characteristics are presented for both pre- and post-operative carotid arteries along with visualization data of 3 dimensional, 3 component velocity fields.

The objective of the study was to evaluate the performance of magnetic resonance imaging (MRI) for the diagnosis of appendicitis during pregnancy. We conducted a retrospective review of all MRI scans performed at our institution, between 2006 and 2012, for the evaluation of suspected appendicitis in pregnant women. Details of the MRI scans performed were obtained from the radiology information system as well as details of any ultrasounds carried out for the same indication. Clinical and pathological data were obtained by retrospective chart review. The study population comprised 63 patients, and 8 patients underwent a second MRI scan during the same pregnancy. A total of 71 MRI scans were reviewed. The appendix was identified on 40 scans (56.3%). Sensitivity of MRI was 75% and specificity was 100% for the diagnosis of appendicitis in pregnant women. When cases with right lower quadrant inflammatory fat stranding or focal fluid, without appendix visualization, were classified as positive for appendicitis, MRI sensitivity increased to 81.3% but specificity decreased to 96.4%. MRI is sensitive and highly specific for the diagnosis of appendicitis during pregnancy and should be considered as a first line imaging study for this clinical presentation.

2017-01-01

This targeted chart review study reports the first ever detailed global account of clinical approaches adopted to detect and manage anastomotic leaks identified during surgery in routine clinical practice. 156 surgeons from eight countries retrospectively extracted data from surgical records of 458 patients who underwent colorectal surgery with an identified intraoperative leak at the circular anastomosis. Demographic details, procedures, and outcomes were analyzed descriptively, by country. Most surgeries were performed laparoscopically (57.6%), followed by open surgeries (35.8%). The burden of intraoperative leaks on the healthcare system is driven in large part by the additional interventions such as using a sealant, recreating the anastomosis, and diverting the anastomosis to a colostomy bag, undertaken to manage the leak. The mean duration of hospitalization was 19.9 days. Postoperative anastomotic leaks occurred in 62 patients (13.5%), most frequently 4 to 7 days after surgery. Overall, country-specific differences were observed in patient characteristics, surgical procedures, method of diagnosis of intraoperative leak, interventions, and length of hospital stay. The potential cost of time and material needed to repair intraoperative leaks during surgery is substantial and often hidden to the healthcare system, potentially leading to an underestimation of the impact of this complication.

Background and PurposeTo evaluate feasibility and impact of dual aspiration technique (DAT) within stent-assisted mechanical thrombectomy on procedural parameters and clinical outcome.Materials and MethodsWithin 16 months, 76 consecutive patients (mean age 70.7 year; range 33–89) underwent stent-assisted mechanical thrombectomy. Of 52 enrolled patients (68.4 %) with occlusion of the anterior circulation, 22 patients (42.3 %) underwent DAT; 30 patients (57.7 %) were treated in conventional monoaspiration technique (MAT). Epidemiological data, clinical and imaging characteristics (mRS, NIHSS, ASPECTS) as well as procedural details were analyzed (TICI, number of retrieval, procedure time). Clinical outcome was determined with mRS at discharge and after 90 days.ResultsIn the context of DATmore » additional carotid artery stenting was required in 45.5 % (10/22) in underlying tandem lesion (vs. 0/30 MAT). No differences were found in NIHSS at admission (MAT: 20.5, range 15–29; DAT: 18.6; range 11–25), mRS at admission (MAT: 4.6 vs. DAT: 4.57) or ASPECT score (MAT: 8.3, ±1.5; DAT: 8.4, ±1.5; P > 0.05). TICI ≥ 2b/3 was conducted in 90 % (MAT) and 100 % (DAT), respectively. The procedure time was longer in the MAT group (65 min, ±25.9, range 18–126) compared to the DAT group (49.7 min, ±15, range 32–101; P = 0.016). The clinical outcome increased from admission to discharge and in follow-up after 90 days (mRS ≥ 2: MAT: 53.3 %, DAT: 54.5 %; P > 0.05).ConclusionsThe dual aspiration technique with an additional intermediate guide catheter placed closed to the stent retriever leads to decreased procedure time in the anterior circulation.

Quantifying temporal glucose variability in diabetes via continuous glucose monitoring: mathematical methods and clinical application.

2005-12-01

Continuous glucose monitors (CGMs) collect detailed blood glucose (BG) time series, which carry significant information about the dynamics of BG fluctuations. In contrast, the methods for analysis of CGM data remain those developed for infrequent BG self-monitoring. As a result, important information about the temporal structure of the data is lost during the translation of raw sensor readings into clinically interpretable statistics and images. The following mathematical methods are introduced into the field of CGM data interpretation: (1) analysis of BG rate of change; (2) risk analysis using previously reported Low/High BG Indices and Poincare (lag) plot of risk associated with temporal BG variability; and (3) spatial aggregation of the process of BG fluctuations and its Markov chain visualization. The clinical application of these methods is illustrated by analysis of data of a patient with Type 1 diabetes mellitus who underwent islet transplantation and with data from clinical trials. Normative data [12,025 reference (YSI device, Yellow Springs Instruments, Yellow Springs, OH) BG determinations] in patients with Type 1 diabetes mellitus who underwent insulin and glucose challenges suggest that the 90%, 95%, and 99% confidence intervals of BG rate of change that could be maximally sustained over 15-30 min are [-2,2], [-3,3], and [-4,4] mg/dL/min, respectively. BG dynamics and risk parameters clearly differentiated the stages of transplantation and the effects of medication. Aspects of treatment were clearly visualized by graphs of BG rate of change and Low/High BG Indices, by a Poincare plot of risk for rapid BG fluctuations, and by a plot of the aggregated Markov process. Advanced analysis and visualization of CGM data allow for evaluation of dynamical characteristics of diabetes and reveal clinical information that is inaccessible via standard statistics, which do not take into account the temporal structure of the data. The use of such methods improves the assessment of patients' glycemic control.

The aim of this study is to describe the prevalence, anatomy, associations and clinical impact of partial anomalous pulmonary venous return in patients with Turner syndrome. All Turner patients who presented at our Turner clinic, between January 2007 and October 2015 were included in this study and underwent ECG, echocardiography and advanced imaging such as cardiac magnetic resonance or computed tomography as part of their regular clinical workup. All imaging was re-evaluated and detailed anatomy was described. Partial anomalous pulmonary venous return was diagnosed in 24 (25%) out of 96 Turner patients included and 14 (58%) of these 24 partial anomalous pulmonary venous return had not been reported previously. Right atrial or ventricular dilatation was present in 11 (46%) of 24 partial anomalous pulmonary venous return patients. When studied with advanced imaging modalities and looked for with specific attention, PAPVR is found in 1 out of 4 Turner patients. Half of these patients had right atrial and/or ventricular dilatation. Evaluation of pulmonary venous return should be included in the standard protocol in all Turner patients. Copyright © 2017.

OBJECTIVE To compare outcomes for laparoscopic ovariectomy (LapOVE) and laparoscopic-assisted ovariohysterectomy (LapOVH) in dogs. DESIGN Retrospective case series. ANIMALS 278 female dogs. PROCEDURES Medical records of female dogs that underwent laparoscopic sterilization between 2003 and 2013 were reviewed. History, signalment, results of physical examination, results of preoperative diagnostic testing, details of the surgical procedure, durations of anesthesia and surgery, intraoperative and immediate postoperative (ie, during hospitalization) complications, and short- (≤ 14 days after surgery) and long-term (> 14 days after surgery) outcomes were recorded. Data for patients undergoing LapOVE versus LapOVH were compared. RESULTS Intraoperative and immediate postoperative complications were infrequent, and incidence did not differ between groups. Duration of surgery for LapOVE was significantly less than that for LapOVH; however, potential confounders were not assessed. Surgical site infection was identified in 3 of 224 (1.3%) dogs. At the time of long-term follow-up, postoperative urinary incontinence was reported in 7 of 125 (5.6%) dogs that underwent LapOVE and 12 of 82 (14.6%) dogs that underwent LapOVH. None of the dogs had reportedly developed estrus or pyometra by the time of final follow-up. Overall, 205 of 207 (99%) owners were satisfied with the surgery, and 196 of 207 (95%) would consider laparoscopic sterilization for their dogs in the future. CONCLUSIONS AND CLINICAL RELEVANCE Results suggested that short- and long-term outcomes were similar for female dogs undergoing sterilization by means of LapOVE or LapOVH; however, surgery time may have been shorter for dogs that underwent LapOVE. Most owners were satisfied with the outcome of laparoscopic sterilization.

Multidetector coronary computed tomographic angiography (CCTA) demonstrates high accuracy for the detection and exclusion of coronary artery disease (CAD) and predicts adverse prognosis. To date, opportunity costs relating the clinical and economic outcomes of CCTA compared with other methods of diagnosing CAD, such as myocardial perfusion single-photon emission computed tomography (SPECT), remain unknown. An observational, multicenter, patient-level analysis of patients without known CAD who underwent CCTA or SPECT was performed. Patients who underwent CCTA (n = 1,938) were matched to those who underwent SPECT (n = 7,752) on 8 demographic and clinical characteristics and 2 summary measures of cardiac medications and co-morbidities and were evaluated for 9-month expenditures and clinical outcomes. Adjusted total health care and CAD expenditures were 27% (p <0.001) and 33% (p <0.001) lower, respectively, for patients who underwent CCTA compared with those who underwent SPECT, by an average of $467 (95% confidence interval $99 to $984) for CAD expenditures per patient. Despite lower total health care expenditures for CCTA, no differences were observed for rates of adverse cardiovascular events, including CAD hospitalizations (4.2% vs 4.1%, p = NS), CAD outpatient visits (17.4% vs 13.3%, p = NS), myocardial infarction (0.4% vs 0.6%, p = NS), and new-onset angina (3.0% vs 3.5%, p = NS). Patients without known CAD who underwent CCTA, compared with matched patients who underwent SPECT, incurred lower overall health care and CAD expenditures while experiencing similarly low rates of CAD hospitalization, outpatient visits, myocardial infarction, and angina. In conclusion, these data suggest that CCTA may be a cost-efficient alternative to SPECT for the initial coronary evaluation of patients without known CAD.

Background Despite having the largest population in Africa, Nigeria has no accurate population based data to plan and evaluate eye care services. A national survey was undertaken to estimate the prevalence and determine the major causes of blindness and low vision. This paper presents the detailed methodology used during the survey. Methods A nationally representative sample of persons aged 40 years and above was selected. Children aged 10–15 years and individuals aged <10 or 16–39 years with visual impairment were also included if they lived in households with an eligible adult. All participants had their height, weight, and blood pressure measured followed by assessment of presenting visual acuity, refractokeratomery, A-scan ultrasonography, visual fields and best corrected visual acuity. Anterior and posterior segments of each eye were examined with a torch and direct ophthalmoscope. Participants with visual acuity of < = 6/12 in one or both eyes underwent detailed examination including applanation tonometry, dilated slit lamp biomicroscopy, lens grading and fundus photography. All those who had undergone cataract surgery were refracted and best corrected vision recorded. Causes of visual impairment by eye and for the individual were determined using a clinical algorithm recommended by the World Health Organization. In addition, 1 in 7 adults also underwent a complete work up as described for those with vision < = 6/12 for constructing a normative data base for Nigerians. Discussion The field work for the study was completed in 30 months over the period 2005–2007 and covered 305 clusters across the entire country. Concurrently persons 40+ years were examined to form a normative data base. Analysis of the data is currently underway. Conclusion The methodology used was robust and adequate to provide estimates on the prevalence and causes of blindness in Nigeria. The survey would also provide information on barriers to accessing services, quality of life of visually impaired individuals and also provide normative data for Nigerian eyes. PMID:18808712

Tumour-induced osteomalacia (TIO) is a rare disorder characterized by hypophosphataemic osteomalacia caused by small mesenchymal tumours secreting fibroblast growth factor 23 (FGF 23). The most difficult part in the management of these patients is the localization of tumours causing TIO. We describe the utility of Gallium (Ga)-68 DOTANOC PET/CT in the localization of tumours causing TIO. The study was conducted in a single tertiary referral university teaching hospital in India. Ten patients with TIO who underwent Ga-68 DOTANOC PET/CT from the time period 2009 to 2014 were included in this study. Their detailed clinical history, biochemical parameters, imaging modalities, surgical interventions, histopathology and outcomes were reviewed. Ga-68 DOTANOC PET/CT could correctly localize the tumours in TIO in 9 of the 10 cases in which it was performed. Complete resection of the tumour led to full clinical recovery in six of the ten patients; two patients who had partial resection and one patient who underwent radiofrequency ablation showed partial remission. One patient in whom Ga-68 DOTANOC PET/CT was positive in vertebral body with a low standardized uptake value (SUV) did not show up the tumour on surgery. We conclude that Ga-68 DOTANOC PET/CT can be used as the first imaging modality in patients diagnosed with TIO. The extremely good outcome following the resection of these small otherwise undiagnosed tumours far outweighs its cost even in resource limited settings. © 2015 John Wiley & Sons Ltd.

Dolichandrone platycalyx, commonly known as Nile trumpet tree, is believed to have originated in East Africa. However, this and the variants of this tree are found in Europe, Asia, and America (California and Florida). The tree mostly grows in tropical climates, but temperate species are also found. This study was designed to evaluate the allergenicity of D. platycalyx, one of the most common entomophilous avenue trees in Karnataka state, and to determine the pollen production of D. platycalyx. All of the patients with allergic rhinitis and asthma attending a tertiary care center in South India during August 2007 to March 2008 underwent a detailed clinical evaluation and skin-prick testing to common allergens along with D. platycalyx. Control subjects without any symptoms of respiratory allergy also underwent skin testing. The pollen counts were determined for a mature unopened flower of D. platycalyx. A total of 317 subjects with respiratory allergy and 30 controls were included in the study. A significant percentage (16.1%) of patients evaluated were observed to be sensitive to Dolichandrone pollen extract by skin-prick testing, whereas none of the control subjects were found to be sensitized. D. platycalyx was the fourth most common sensitizer after Parthenium hysterophorus, Prosopis juliflora, and Artemesia vulgaris. D. platycalyx was found to be a moderate pollen producer at 66,000 pollens/flower. Sensitization to D. platycalyx is common in subjects with respiratory allergies. The clinical relevance of this sensitization and other entomophilous plants needs additional study.

Recently, Poly Implant Prothèse silicone breast implants were recalled from the European market. The authors studied 112 women and previously published data on rupture prevalence. Women are presenting with symptoms they feel may be a result of ruptured implants. The authors' aim was to study the clinical consequences of Poly Implant Prothèse implants. One hundred twelve women with 224 proven Poly Implant Prothèse implants after 10 years of implantation were enrolled in this study. All women underwent physical examination and magnetic resonance imaging and were interviewed regarding symptoms. Details of the explantations of 35 women with at least one ruptured implant were documented. Tissue from 10 women was sent for pathologic investigation. Of 112 women, 34 (30.4 percent) had symptoms attributable to their implants. Physical examination showed that 12 of the 121 women (10.7 percent) had findings suggestive of rupture, most commonly pain. Three had lymphadenopathy that seemed to correlate with implant rupture or excessive "gel bleed." Pathologic findings showed no malignancies. Eight women who underwent explantation had no implant rupture. Excessive gel bleed was documented in half of them. Clinical consequences of women with Poly Implant Prothèse implants are comparable to those reported in the literature of other manufacturers. Neither complaints nor findings at physical examination had a significant correlation with implant rupture at explantation. Magnetic resonance imaging is still the preferred method compared with physical examination for diagnosing rupture. The low specificity was probably caused by the difficulty in differentiating between rupture and excessive gel bleed in these implants.

Purpose: This study was designed to investigate the long-term angiographic and clinical outcomes of percutaneous transluminal angioplasty (PTA) of the arteria profunda femoralis (PFA), in a series of patients suffering from critical limb ischemia (CLI) or severe intermittent claudication (IC). Methods: Our department's database was searched to identify patients who underwent PTA or bail-out stenting of the PFA. Among the study's inclusion criteria were Rutherford categories 3-6 and {>=}70% stenosis of the PFA. Only de novo stenotic lesions were assessed. Primary endpoints were technical success, angiographic lesion primary patency, angiographic binary in-lesion restenosis, and target lesion recanalization (TLR) rates. Secondarymore » endpoints included patient survival, limb salvage, and complication rates. Patient's baseline demographics, lesion, and procedural details were analyzed. Results: Between 2001 and 2011, 20 consecutive patients (17 males) with a mean age of 73 {+-} 9 (range 53-87) years underwent PTA or bail-out stenting in 23 PFA lesions. Critical limb ischemia was the indication in eight of 20 patients (40%). The mean lesion length was 31 {+-} 9.5 mm. The procedural technical success was 100% (23/23), whereas mean time angiographic and clinical follow-up was 26.8 {+-} 24.6 months. According to the Kaplan-Meier analysis, primary patency and binary restenosis rate were 95 and 86.1% respectively up to 8 years follow-up. No TLR procedures were performed. The 8-year patient survival and limb salvage rates were 87.5 and 84.7% respectively. Conclusions: PTA or stenting of focal, stenotic, PFA lesions, in patients suffering from CLI or IC, exhibit high long-term primary patency rates, as well as low binary restenosis and TLR rates. Large, multicenter studies are required to validate these results.« less

Clinical verification of a unilateral otolith test

Wetzig, J.; Hofstetter-Degen, K.; Maurer, J.; von Baumgarten, R. J.

In a previous study 13 we reported promising results for a new test to differentiate in vivo unilateral otolith functions. That study pointed to a need for further validation on known pathological cases. In this presentation we will detail the results gathered on a group of clinically verified vestibular defectives (verum) and a normal (control) group. The subjects in the verum group were former patients of the ENT clinic of the university hospital. These subjects had usually suffered from neurinoma of the VIIth cranial nerve or inner ear infections. All had required surgical intervention including removal of the vestibular system. The patients were contacted usually two or more years postoperatively. A group of students from the pre- and clinical phase of medical training served as control. Both groups were subjected to standardized clinical tests. These tests served to reconfirm the intra- or postoperative diagnosis of unilateral vestibular loss in the verum group. In the control group they had to establish the normalcy of the responses of the vestibular system. Both groups then underwent testing on our exccentric rotary chair in the manner described before 13. Preliminary results of the trials indicate that this test may indeed for the first time offer a chance to look at isolated otolith apparati in vivo.

To study the relationship between Alzheimer disease (AD) pathology and memory complaints proximate to death. A group of 90 older persons underwent detailed clinical evaluations and brain autopsy at death. The evaluations included administration of questions on subjective memory complaints and clinical classification of dementia and AD. On postmortem examination, neuritic plaques, diffuse plaques, and neurofibrillary tangles in tissue samples from five cortical regions were counted, and a summary measure of overall AD pathology was derived. In addition, amyloid load and tau tangles were quantified in eight regions. In multiple linear regression models adjusted for age, sex, and education, memory complaints were associated with AD pathology, including both amyloid and tau tangles. Subsequent analyses demonstrated that the relationship between memory complaints and AD pathology was present in those with and without dementia, and could not be explained by the potentially confounding effects of depressive symptoms or coexisting common chronic health problems. Memory complaints in older persons may indicate self awareness of a degenerative process.

The aim of this case report was to present a case of multiple calcified tuberculous lymph nodes found on a panoramic radiograph coincidently diagnosed in an endodontic clinic. A detailed discussion on the differential diagnosis of similar such calcification found in the same region is also presented. A 14-year-old girl was referred to our department with the complaint of painless swelling in the left side of the lower jaw. Clinical and radiographical examinations were performed, leading to the initial diagnosis of chronic periapical abscess. The patient's medical history was re-evaluated. Advanced imaging and excisional biopsy were performed in order to confirm the final diagnosis. Regarding the presenting signs and symptoms of bilateral carious mandibular molars, a periapical inflammatory process was considered in the provisional diagnosis. A thorough examination and investigations were suggestive of cervical tuberculous lymphadenitis (scrofula), and the patient underwent excision of the same. The clinician should consider the possibility of chronic granulomatous inflammatory lesions in the differential diagnosis of radiopaque lesions. © 2014 Australian Dental Association.

A 39-year-old African American woman presented for treatment of a symptomatic mandibular right first molar with a large, periapical radiolucency. After initial attempts at endodontic therapy, this tooth was ultimately extracted owing to unabated symptoms. The extraction site underwent ridge preservation grafting, implant placement, and restoration. After 26 months of implant function, the patient returned with clinical symptoms of pain, buccal swelling, and the sensation of a "loose" implant. This case report details a diagnosis of 2 distinct disease entities associated with the implant site, a cemento-ossifying fibroma and florid cemento-osseous dysplasia of the mandible. This diagnosis was determined from clinical, surgical, radiographic, and histopathologic evidence after biopsy and removal of the previously osseointegrated implant following postinsertion failure by fibrous encapsulation. Before implant therapy, it is essential to conduct a thorough radiographic evaluation of any dental arch with suspected bony lesions to prevent implant failure. Published by Mosby, Inc.

Patients with Noonan syndrome often require surgery at young ages. They are at high risk of perioperative bleeding from coagulation defects that might not have been detected by routine screening. These risks are rarely described in the oral and maxillofacial surgery (OMS) literature. The aim of this study was to evaluate the perioperative bleeding risks associated with Noonan syndrome and to propose preoperative guidelines. This report describes a retrospective case series of patients with Noonan syndrome who underwent OMS procedures during a continuous observational period (2013 through 2016) in the authors' center. Clinical data, blood screening test results, and perioperative bleeding were analyzed. Five patients (age, 4 to 20 yr) with Noonan syndrome who underwent OMS procedures were included in this study. One patient presented a spontaneous bleeding tendency (epistaxis requiring cauterization). Blood screening showed clotting defects in 3 patients. One patient presented abnormal perioperative bleeding owing to a mild defect in factor XI. Patients with Noonan syndrome must be referred to a hematologist for specific preoperative investigations and for adapted perioperative management.

To examine clinical outcomes and survivorship in patients aged 60 years or older who underwent hip arthroscopy for management of hip pain. Prospectively collected data for patients 60 or older undergoing hip arthroscopy were obtained. All patients were indicated for hip arthroscopy based on standard preoperative examination as well as routine and advanced imaging. Demographic data, diagnosis, and details regarding operative procedures were collected. Baseline preoperative modified Harris Hip Scores (mHHS) and Non-arthritic Hip Scores (NAHS) were compared to mHHS and NAHS at the 2-year follow-up. Survivorship was assessed to determine failure rates, with failure defined as any subsequent ipsilateral revision arthroscopic surgery and/or hip arthroplasty. Forty-two patients met inclusion criteria. Mean age (standard deviation) and body mass index were 65.8 years (4.5 years) and 26.1 (4.7), respectively. Baseline mean mHHS and NAHS for all patients improved from 47.8 (±12.5) and 47.3 (±13.6) to 75.6 (±17.6) and 78.3 (±18.6), respectively (P < .001 for both). Five patients (11.9%) met failure criteria and underwent additional surgery at an average of 14.8 (8-30) months. Three underwent conversion to total hip arthroplasty (7.1%), whereas 2 had revision arthroscopy with cam/pincer resection and labral repair for recurrent symptoms (4.7%). One- and 2-year survival rates were 95.2% and 88.9%, respectively. Our results suggest that in patients 60 or older with Tonnis grade 0 or 1 osteoarthritic changes on initial radiographs-treatment with hip arthroscopy can lead to reliable improvement in early outcomes. As use of hip arthroscopy for treatment of mechanical hip pain increases, additional studies with long-term follow-up are needed. Level IV, therapeutic case series.

Objectives: To report on six independent and isolated cases demonstrating thumb aplasia as an essentially limb-specific phenotype. Methods: The subjects were ascertained during 2011-2013 from six different geographic regions of Pakistan, and underwent detailed clinical and phenotypic examination. Results: The affected arms of patients had complete absence of first digital rays, medial inclinations of second and fifth fingers, narrowing of palms, missing carpals, and shortening of zeugopod. All the subjects were presented with isolated and sporadic limb deficiencies, and five had no family history of limb or any other malformation. Parental consanguinity was denied in majority of the cases. We present detailed phenotypic manifestation of thumb apalsia in these subjects. Conclusion: Thumb aplasia markedly impairs the normal function of affected hand. Surgical procedures like pollicisation of the index finger should be employed to improve the quality of life of these subjects. There is so far no specific genetic factor known for isolated thumb aplasia, compromising an accurate genetic counseling. Collection of patients with similar phenotypic presentations could be useful in further molecular genetic investigations. PMID:24949004

Spigelian hernia is a rare hernia of the ventral abdominal wall accounting for 1-2% of all hernias. Incarceration of a Spigelian hernia has been reported in 17-24% of the cases. We herein describe an extremely rare case of a colonic obstruction secondary to an incarcerated Spigelian hernia in a severely obese patient. Physical examination was inconclusive and diagnosis was established by computed tomography scans. The patient underwent an open intraperitoneal mesh repair. A high level of suspicion and awareness is required as clinical findings of a Spigelian hernia are often nonspecific especially in obese patients. Computed tomography scan provides detailed information for the surgical planning. Open mesh repair is safe in the emergent surgical intervention of a complicated Spigelian hernia in severely obese patients.

2011-05-10

Epithelioid haemangioendothelioma (EHE) is a rare tumour of vascular origin, characterised by celular proliferation, endotelial, epitelioid or hystiocitoid. It may develop in any organ, but it is more common in lung and liver. Surgery is the recommended treatment; however, in case of a potentially benign situation, an expectant attitude should be adopted. The case reports a 71-year-old female who underwent a laparotomy for a colonic adenocarcinoma. During surgery, a polypoid lesion in the dependency of the gastric wall was found incidentally, which was removed. Histopathology and immunohistochemical analysis confirmed the diagnosis of EHE. Gastric vascular neoplasms represent about 0.9-3.3% of all gastric tumours. Usually have a good prognosis, but due to the borderline biological behaviour of these tumours, it is important to have a detailed clinical evaluation at follow-up of these patients.

Granulocytic sarcoma (GS) is a rare extramedullary malignant tumor composed of immature myeloid cells. It is strongly associated with acute myeloid leukaemia, chronic myeloproliferative diseases. Occurrence of GS in the oral cavity is extremely uncommon. Present case reported an unusual occurrence of GS without leukemia involving maxillary sinus of a child. The patient underwent chemotherapy followed by radiotherapy with complete remission. A long-term follow-up of the patient was carried without any evidence of recurrence with special focus on diagnostic difficulties. The present case highlights the perplexity in diagnosing such lesions with emphasis on the need of careful interpretation of all clinical, radiographic, histopathological and immunohistochemical details as it is one of the most frequently misdiagnosed disorder.

Cryopyrin-associated periodic syndrome (CAPS) is a group of inherited autoinflammatory disorders caused by mutations in the NLRP3 gene resulting in the overproduction of interleukin 1β. NLRP3 mutations cause a broad clinical phenotype of CAPS. The aims of the study were to evaluate clinical, laboratory, and genetic features of a 5-generation family with CAPS focusing in detail on ocular symptoms. In a retrospective observational cohort study, consecutive family members were screened for the presence of the NLRP3 mutation. Patients underwent standardized clinical, laboratory, and ophthalmological assessments. The genotype-specific risk of ophthalmological findings and other organ symptoms was determined. Twenty-nine patients were clinically affected. The A439V mutation encoded by exon 3 of the NLRP3 gene was found in 15 of 37 family members (41%). The most common clinical features were musculoskeletal symptoms, headaches, and ophthalmological symptoms. The mutation-positive patients were characterized by more frequent skin rashes, ocular symptoms, arthralgia, arthritis, and severe Muckle-Wells syndrome (MWS) Disease Activity Score. Rosacea was diagnosed in 8 patients. The NLRP3 mutation A439V is associated with a heterogeneous clinical spectrum of familial cold autoinflammatory syndrome/MWS-overlap syndrome. Skin rash and eye diseases, such as conjunctivitis and uveitis, were positively correlated with this mutation.

We determined factors associated with long-term outcomes of patients who underwent successful percutaneous mitral balloon valvuloplasty (PMV). Between August 1980 and May 2013, 1187 patients underwent PMV at Severance Hospital, Seoul, Korea. A total of 742 patients who underwent regular clinic visits for more than 10 years were retrospectively analyzed. The endpoints consisted of repeated PMV, mitral valve (MV) surgery, and cardiovascular-related death. The optimal result, defined as a post-PMV mitral valve area (MVA) >1.5 cm² and mitral regurgitation ≤Grade II, was obtained in 631 (85%) patients. Over a mean follow up duration of 214±50 months, 54 (7.3%) patients underwent repeat PMV, 4 (0.5%) underwent trido-PMV, and 248 (33.4%) underwent MV surgery. A total of 33 patients (4.4%) had stroke, and 35 (4.7%) patients died from cardiovascular-related reasons. In a multivariate analysis, echocardiographic score [p=0.003, hazard ratio=1.56, 95% confidence interval (CI): 1.01-2.41] and post-MVA cut-off (p<0.001, relative risk=0.39, 95% CI: 0.37-0.69) were the only significant predictors of long-term clinical outcomes after adjusting for confounding variables. A post-MVA cut-off value of 1.76 cm² showed satisfactory predictive power for poor long-term clinical outcomes. In this long-term follow up study (up to 20 years), an echocardiographic score >8 and post-MVA ≤1.76 cm² were independent predictors of poor long-term clinical outcomes after PMV, including MV reintervention, stroke, and cardiovascular-related death. © Copyright: Yonsei University College of Medicine 2018

Postural and Intention Tremors: A Detailed Clinical Study of Essential Tremor vs. Parkinson’s Disease

PubMed Central

Sternberg, Eliezer J.; Alcalay, Roy N.; Levy, Oren A.; Louis, Elan D.

2013-01-01

Background: An estimated 30–50% of essential tremor (ET) diagnoses are incorrect, and the true diagnosis in those patients is often Parkinson’s disease (PD) or other tremor disorders. There are general statements about the tremor in these ET and PD, but published data on the more subtle characteristics of tremor are surprisingly limited. Postural tremor may occur in both disorders, adding to the difficulty. There are several anecdotal impressions regarding specific features of postural tremor in ET vs. PD, including joint distribution (e.g., phalanges, metacarpal-phalangeal joints, wrist), tremor directionality (e.g., flexion-extension vs. pronation-supination), and presence of intention tremor. However, there is little data to support these impressions. Methods: In this cross-sectional study, 100 patients (ET, 50 PD) underwent detailed videotaped neurological examinations. Arm tremor was rated by a movement disorder neurologist who assessed severity and directionality across multiple joints. Results: During sustained arm extension, ET patients exhibited more wrist than metacarpal-phalangeal and phalangeal joint tremor than did PD patients (p < 0.001), and more wrist flexion-extension tremor than wrist pronation-supination tremor (p < 0.001). During the finger-nose-finger maneuver, intention tremor was present in approximately one in four (28%) ET patients vs. virtually none (4%) of the Parkinson’s patients (p < 0.001). Conclusions: We evaluated the location, severity, and directionality of postural tremor in ET and PD, and the presence of intention tremor, observing several clinical differences. We hope that detailed phenomenological data on tremor in ET and PD will help practicing physicians delineate the two diseases. PMID:23717300

The outcomes of children with congenital hemolytic anemia (CHA) undergoing total splenectomy (TS) or partial splenectomy (PS) remain unclear. In this study, we collected data from 100 children with CHA who underwent TS or PS from 2005–2013 at 16 sites in the Splenectomy in Congenital Hemolytic Anemia (SICHA) consortium using a patient registry. We analyzed demographics and baseline clinical status, operative details, and outcomes at 4, 24, and 52 weeks after surgery. Results were summarized as hematologic outcomes, short-term adverse events (AEs) (≤ 30 days after surgery), and long-term AEs (31–365 days after surgery). For children with hereditary spherocytosis, after surgery there was an increase in hemoglobin (baseline 10.1 ± 1.8 gm/dl, 52 week 12.8 ± 1.6 gm/dl; mean ± SD), decrease in reticulocyte and bilirubin as well as control of symptoms. Children with sickle cell disease had control of clinical symptoms after surgery, but had no change in hematologic parameters. There was an 11% rate of short-term AEs and 11% rate of long-term AEs. As we accumulate more subjects and longer follow-up, use of a patient registry should enhance our capacity for clinical trials and engage all stakeholders in the decision-making process.

Goossen, William; Goossen-Baremans, Anneke

2013-01-01

This chapter describes the need for Detailed Clinical Models for contemporary Electronic Health Systems, data exchange and data reuse. It starts with an explanation of the components related to Detailed Clinical Models with a brief summary of knowledge representation, including terminologies representing clinic relevant "things" in the real world, and information models that abstract these in order to let computers process data about these things. Next, Detailed Clinical Models are defined and their purpose is described. It builds on existing developments around the world and accumulates in current work to create a technical specification at the level of the International Standards Organization. The core components of properly expressed Detailed Clinical Models are illustrated, including clinical knowledge and context, data element specification, code bindings to terminologies and meta-information about authors, versioning among others. Detailed Clinical Models to date are heavily based on user requirements and specify the conceptual and logical levels of modelling. It is not precise enough for specific implementations, which requires an additional step. However, this allows Detailed Clinical Models to serve as specifications for many different kinds of implementations. Examples of Detailed Clinical Models are presented both in text and in Unified Modelling Language. Detailed Clinical Models can be positioned in health information architectures, where they serve at the most detailed granular level. The chapter ends with examples of projects that create and deploy Detailed Clinical Models. All have in common that they can often reuse materials from earlier projects, and that strict governance of these models is essential to use them safely in health care information and communication technology. Clinical validation is one point of such governance, and model testing another. The Plan Do Check Act cycle can be applied for governance of Detailed Clinical Models. Finally, collections of clinical models do require a repository in which they can be stored, searched, and maintained. Governance of Detailed Clinical Models is required at local, national, and international levels.

To determine the type of glaucoma in subjects with diabetes mellitus detected during a diabetic retinopathy screening program and to determine any association between diabetic retinopathy (DR) and glaucoma. This is a population-based prospective cross-sectional study, in which subjects with diabetes mellitus underwent screening for DR in a primary care outpatient clinic. Digital fundus photographs were taken and graded for presence/absence and severity of DR. During this grading, those fundus photographs showing increased cup-to-disc ratio (CDR) (≥0.6) were identified and these patients were referred to the specialist ophthalmology clinic for detailed examination. The presence of glaucoma was established based on CDR and abnormal visual field (VF) defects according to Hodapp-Parrish-Anderson's criteria. An elevation of intraocular pressure was not required for the diagnosis of glaucoma. The patients said to have definite glaucoma were those with vertical CDR>/=0.6, glaucomatous defects on VF examination, or retinal nerve fiber thinning if VF was unreliable. Of the 2182 subjects who underwent screening, 81 subjects (3.7%) had increased CDR and 40 subjects (1.8%) had confirmed glaucoma. Normal-tension variant of primary open-angle glaucoma was the most prevalent type (1.2%) We did not find any evidence that DR is a risk factor for glaucoma [odds ratio for DR vs. no DR=1.22 (95% confidence interval, 0.59-2.51)]. The overall prevalence of glaucoma in this diabetic population, based on finding increased cupping of optic disc in a teleretinal screening program was 1.8% (95% confidence interval, 1.0-3.0).

The Korean Brain Aging Study for the Early Diagnosis and Prediction of Alzheimer's disease (KBASE) aimed to recruit 650 individuals, aged from 20 to 90 years, to search for new biomarkers of Alzheimer's disease (AD) and to investigate how multi-faceted lifetime experiences and bodily changes contribute to the brain changes or brain pathologies related to the AD process. All participants received comprehensive clinical and neuropsychological evaluations, multi-modal brain imaging, including magnetic resonance imaging, magnetic resonance angiography, [ 11 C]Pittsburgh compound B-positron emission tomography (PET), and [ 18 F]fluorodeoxyglucose-PET, blood and genetic marker analyses at baseline, and a subset of participants underwent actigraph monitoring and completed a sleep diary. Participants are to be followed annually with clinical and neuropsychological assessments, and biannually with the full KBASE assessment, including neuroimaging and laboratory tests. As of March 2017, in total, 758 individuals had volunteered for this study. Among them, in total, 591 participants-291 cognitively normal (CN) old-aged individuals, 74 CN young- and middle-aged individuals, 139 individuals with mild cognitive impairment (MCI), and 87 individuals with AD dementia (ADD)-were enrolled at baseline, after excluding 162 individuals. A subset of participants (n=275) underwent actigraph monitoring. The KBASE cohort is a prospective, longitudinal cohort study that recruited participants with a wide age range and a wide distribution of cognitive status (CN, MCI, and ADD) and it has several strengths in its design and methodologies. Details of the recruitment, study methodology, and baseline sample characteristics are described in this paper.

Purpose: Delayed breast cellulitis (DBC) is characterized by the late onset of breast erythema, edema, tenderness, and warmth. This retrospective study analyzes the risk factors and clinical course of DBC. Methods and Materials: From 1985 through 2004, 580 sequential women with 601 stage T0-2N0-1 breast cancers underwent breast conserving therapy. Cases of DBC were identified according to accepted clinical criteria: diffuse breast erythema, edema, tenderness, and warmth occurring >3 months after definitive surgery and >3 weeks after radiotherapy. Potential risk factors analyzed included patient comorbidity, operative technique, acute complications, and details of adjunctive therapy. Response to treatment and long-term outcomemore » were analyzed to characterize the natural course of this syndrome. Results: Of the 601 cases, 16%, 52%, and 32% were Stage 0, I, and II, respectively. The overall incidence of DBC was 8% (50/601). Obesity, ecchymoses, T stage, the presence and aspiration of a breast hematoma/seroma, removal of >5 axillary lymph nodes, and arm lymphedema were significantly associated with DBC. The median time to onset of DBC from the date of definitive surgery was 226 days. Ninety-two percent of DBC patients were empirically treated with antibiotics. Fourteen percent required more invasive intervention. Twenty-two percent had recurrent episodes of DBC. Ultimately, 2 patients (4%) underwent mastectomy for intractable breast pain related to DBC. Conclusion: Although multifactorial, we believe DBC is primarily related to a bacterial infection in the setting of impaired lymphatic drainage and may appear months after completion of radiotherapy. Invasive testing before a trial of antibiotics is generally not recommended.« less

The timing of cardiac surgery after stroke in infective endocarditis (IE) remains controversial. We examined the relationship between the timing of surgery after stroke and the incidence of in-hospital and 1-year mortalities. Data were obtained from the International Collaboration on Endocarditis-Prospective Cohort Study of 4794 patients with definite IE who were admitted to 64 centers from June 2000 through December 2006. Multivariate logistic regression and Cox regression analyses were performed to estimate the impact of early surgery on hospital and 1-year mortality after adjustments for other significant covariates. Of the 857 patients with IE complicated by ischemic stroke syndromes, 198 who underwent valve replacement surgery poststroke were available for analysis. Overall, 58 (29.3%) patients underwent early surgical treatment vs 140 (70.7%) patients who underwent late surgical treatment. After adjustment for other risk factors, early surgery was not significantly associated with increased in-hospital mortality rates (odds ratio, 2.308; 95% confidence interval [CI], .942-5.652). Overall, probability of death after 1-year follow-up did not differ between 2 treatment groups (27.1% in early surgery and 19.2% in late surgery group, P = .328; adjusted hazard ratio, 1.138; 95% CI, .802-1.650). There is no apparent survival benefit in delaying surgery when indicated in IE patients after ischemic stroke. Further observational analyses that include detailed pre- and postoperative clinical neurologic findings and advanced imaging data (eg, ischemic stroke size), may allow for more refined recommendations on the optimal timing of valvular surgery in patients with IE and recent stroke syndromes.

The technique for decompression of Chiari type I malformation relies on open exposure of craniocervical junction for suboccipital craniectomy and upper cervical laminectomy with or without duraplasty. There is no detailed technical report of a minimally invasive approach for Chiari decompression in adults. To describe a mini-open technique for decompression of Chiari type I malformation (including duraplasty) in adults. Six consecutive adult patients with symptomatic Chiari type I malformation underwent decompression through a 3 to 4 cm midline incision via a speculum retractor. All patients underwent a limited suboccipital craniectomy and C1 laminectomy with an ultrasonic bone scalpel. All patients underwent duraplasty with a synthetic dural substitute. In the 2 patients with syringomyelia, the arachnoid was opened and intradural dissection was carried out. In the remaining 4 patients, the arachnoid was left intact. All operations were completed successfully through the mini-open exposure. Mean surgery time, blood loss, and length of stay were 114 min, 55 mL, and 1.3 days, respectively. Mean follow-up was 13.2 months (range 9-18). All patients had excellent clinical outcomes as defined by scores of 15 (3 patients) or 16 (3 patients) on Chicago Chiari Outcome Scale. There were no neurological complications or cerebrospinal fluid leaks. Postop computed tomography revealed good boney decompression. In the 2 patients with syringomyelia, MRI at 6 months revealed resolution of the syrinx. Decompression of Chiari type I malformation in adults can be performed safely and effectively through the mini-open exposure described in this report.

To assess the safety of selective use of triple assessment with omission of radiological assessment proposed in patients <40-years old. Data were collected retrospectively for all patients seen in the one-stop breast clinic between January 2014 and August 2015. Demographics, symptoms, diagnostics, and treatment details were recorded. Subgroup and logistic regression analysis was performed to identify predictors for breast cancer. Of the 3,305 patients included, 95.6% (n=3,161) were first-time referrals. 57.6% (n=1,903) had a breast lump, and 4% (n=133) had a high-risk family history; 75.6% (n=2,499) underwent imaging and 16.7% (n=552) underwent a biopsy. The median age was 29 years (interquartile range [IQR]=25-34). Breast cancer was diagnosed in 29 cases (0.88%) and 3.2% (n=105) had surgery. Median referral-to-diagnosis time was 13 days (IQR=9-14) and referral-to-surgery time was 44 days (IQR=34-95). Patients with breast cancer were significantly older (33 versus 28 years, p=0.016). All patients were first-time referrals. Most patients had a breast lump with low suspicion on clinical examination and breast cancer identified on imaging. Time-to-diagnosis (12 versus 14 days, p=0.017) and time-to-surgery (37 versus 67 days, p=0.012) was significantly shorter in the breast cancer group. Comparative older age (odds ratio [OR]=1.08, 95% confidence interval [CI]: 1.01-1.15) and breast lump (OR=11.43,95% CI: 2.72-48.07) were the only significant predictors of cancer on uni/multivariate regression. Triple assessment is also the best practice for all patients in the younger age group. This cohort should not be treated any differently regarding one-stop clinic infrastructure as the cancers detected were not clinically malignant. Missed cancers in this age group would have significant personal, clinical, and legal consequences. Copyright © 2018 The Royal College of Radiologists. Published by Elsevier Ltd.

Foot and ankle injuries (FAI) are very common, with about 6000 cases per day in France. Unlike lateral ankle sprain (LAS), the diagnosis of midtarsal joint sprain (MJS, also known as Chopart's joint sprain) is not widely known. This prospective study aims to detail the epidemiology of MJS and compare it to LAS. The study was conducted within our institution over a period of 16 months. Patients with clinical signs predictive of MJS without radiographic bone lesion underwent ultrasound assessment. MJS was diagnosed in case of at least 1 lesion of the dorsal midtarsal joint ligaments. A total of 2412 patients consulted for FAI; 188 had clinical and radiographic criteria for ultrasound examination. Eighty-two cases of MJS were diagnosed (3.4% of FAIs). Sports injuries were more frequent in MJS (P=0.04), and mechanisms more varied than in LAS, with inversion injury in 75% of cases and plantar hyperflexion in 22%. Sprain was severe in 70% of cases, with complete ligament tear. Clinical and ultrasound analyses correlated in only 40% of cases of MJS, versus 98% for LAS. MJS is frequent, difficult to diagnose clinically, and often severe. Clinical presentation and injury mechanisms differ from ankle sprain. Ultrasound seems to be an indispensable tool in diagnosis.

To clarify the advantages and disadvantages of stenting as a bridge to surgery (BTS) by comparing the clinical features and outcomes of patients who underwent BTS with those of patients who underwent emergency surgery (ES). We assessed technical success, clinical success, surgical procedures, stoma formation, complications, clinicopathological features, and Onodera's prognostic nutritional index (OPNI) in patients who underwent BTS and those who underwent ES. Twenty-six patients underwent stenting, which was successful in 22 (BTS group). The remaining four patients with unsuccessful stenting underwent emergency surgery. A total of 22 patients underwent emergency surgery (ES group). The rates of technical and clinical success were 85.0 and 81.0 %, respectively. The proportion of patients able to be treated by laparoscopic surgery (P = 0.0001) and avoid colostomy (P = 0.0042) was significantly higher in the BTS group. Although the incidence of anastomotic leakage in the two groups was not significantly different, it was significantly reduced by colonoscopic evaluation of obstructive colitis (P = 0.0251). The mean number of harvested lymph nodes (P = 0.0056) and the proportion of D3 lymphadenectomy (P = 0.0241) were significantly greater in the BTS group. Perineural invasion (PNI) was noted in 59.1 and 18.2 % of the BTS group and ES group patients, respectively (P = 0.0053). OPNI and serum albumin decreased significantly after stenting (P = 0.0084). The advantages of stenting as a BTS were that it avoided colostomy and allowed for laparoscopic surgery and lymphadenectomy, whereas its disadvantage lay in the decreased PNI and OPNI levels. A larger study including an analysis of prognosis is warranted.

Clinical and biochemical parameters were analysed in 55 patients who underwent a caesarean section performed using Misgav Ladach method compared to reference group of 41 patients who underwent caesarean section using Pfannenstiel method. Shortened operation time, shortened hospitalisation time and less postoperative morbidity were observed in the Misgav Ladach group. This kind of method seems to have advantages in comparison to Pfannenstiel method.

Intravascular ultrasound (IVUS) imaging has been used extensively in coronary artery interventions and has provided invaluable information for the understanding and treatment of coronary arterial disease. We present here the first description, to our knowledge, of IVUS-guided intracranial arterial interventions in the clinical setting. Two patients underwent intracranial angioplasty and stent placement with the assistance of IVUS for the evaluation of their lesions. One patient underwent stenting to treat an occlusive dissection of the left internal carotid artery that occurred during arteriovenous malformation embolization. Another patient underwent angioplasty and stenting for high-grade restenosis of a basilar artery atherosclerotic lesion. Both patients underwent successful revascularization procedures. The patient with the dissection had a small intraventricular and parenchymal hemorrhage documented by computed tomography 4 hours after treatment, but did not develop hydrocephalus or further hemorrhage. Both patients did well clinically and had no permanent neurological deficits. IVUS provided important information in terms of lesion evaluation, stent selection, and stent placement in each case. IVUS of the intracranial circulation may assist the performance of intracranial angioplasty and stenting. It provides useful information that can affect clinical decisions. It may prove to be a valuable tool in clinical use and enhance our understanding of vascular disease of the intracranial circulation, as it has in the coronary circulation.

Significance of isolated reactive treponemal chemiluminescence immunoassay results.

Isolated reactive serum treponemal chemiluminescence immunoassay (CIA) specimens cause clinical uncertainty. Sera were screened by CIA, and reactive samples underwent reflex testing with rapid plasma reagin (RPR), Treponema pallidum particle agglutination (TPPA), and fluorescent treponemal antibody absorption (FTA Abs) assays. Samples reactive only on the CIA were deemed "isolated" reactive CIA samples. We undertook detailed review of a subset of subjects with isolated reactive CIA specimens. Of 28 261 specimens, 1171 (4.1%) were reactive on CIA, of which 133 (11.3%) had isolated CIA reactivity. Most subjects (66 of 82 [80.5%]) with isolated reactive CIA specimens were from high-prevalence populations. We found evidence of CIA, TPPA, and FTA Abs seroreversion. The median chemiluminescent signal-to-cutoff ratio was similar for isolated reactive CIA sera and sera that were reactive on either FTA Abs or TPPA assays (2.19 vs 2.32; P = .15) but lower than for sera reactive on both FTA Abs and TPPA assays (12.37; P < .001) or for sera reactive on RPR assays (25.53; P < .001). A total of 11 of 20 patients (55%) with an isolated reactive CIA specimen who underwent medical record review had previous or subsequent evidence of syphilis infection. Isolated reactive CIA specimens may represent true T. pallidum infection and may be found after seroreversion of traditional treponemal assays.

This study presents our experience with a series of patients suffering from petrous bone fractures violating the otic capsule who underwent subtotal petrosectomy combined with eustachian tube, middle ear, and mastoid obliteration, with the goal of preventing cerebrospinal fluid (CSF) leak and meningitis. This study enrolled 26 patients between 1997 and 2011. The clinical symptoms, otoscopy, and preoperative and postoperative audiometry and facial function, as well as CSF leak or meningitis, were evaluated in each patient. The entire group underwent a subtotal petrosectomy using the technique described in detail by Fisch. In addition, each patient was interviewed using a questionnaire to evaluate the impact on quality of life. Intraoperatively, we found significant CSF leaks in 14 patients (42.5%). No patient reported other episodes of CSF leak or meningitis after the surgery. The patients' responses of facial nerve function were slightly worse than the House-Brackmann evaluation (50% versus 42.3%; p < 0.05). The vast majority (88.5%) of the patients experienced no social impact. Our findings suggest the importance of not underestimating the risk for CSF leak in the petrous bone fractures violating the otic capsule. Preoperative counseling regarding the various troublesome complications must adequately motivate candidates to undergo surgery by pointing out the positive impact of the proposed treatment.

We report on an adult male initially presenting with gynecomastia and a painless scrotal mass without additional genital anomalies. Hyperpigmentation of the skin following the Blaschko's lines was identified. He underwent gonadectomy because of suspected cancer. Histological analyses revealed an ovotestis with ovulatory activity confirmed by immunohistochemistry with multiple markers. Karyotyping of cultured peripheral blood lymphocytes and a buccal smear revealed a 46,XX/46,XY chimeric constitution with different percentages. Multiple molecular analyses as well as blood typing implied a tetragametic origin. After the unilateral gonadectomy, the patient developed recurrent painful cystic swellings of the remaining gonad. Because of the wish to preserve hormonal activity as well as future fertility, the patient underwent surgical resection of a cystic gonadal area. The removed tissue showed ovulation-related features in addition to both testicular and ovarian tissue, diagnosed as an ovotestis. Testosterone therapy was initiated to suppress the persistently elevated gonadotropins and thereby suppress ovarian activity. During treatment, the recurrent pain complaints and cystic swellings ceased, although gonadotropin levels were not fully suppressed. Based on these observations, the importance of a detailed genetic and pathological diagnosis and the clinical dilemmas including the pros and cons of personalized treatment with gonadal preservative surgery are discussed. © 2017 S.

2015-01-01

Background Residual aneurysm after microsurgical clipping carries a risk of aneurysm growth and rupture. Digital subtraction angiography (DSA) remains the standard to determine the adequacy of clipping. Intraoperative indocyanine green (ICG) angiography is increasingly utilized to confirm optimal clip positioning across the neck and to evaluate the adjacent vasculature. Objective We evaluated the correlation between ICG and DSA in clipped intracranial aneurysms. Methods A retrospective study of patients who underwent craniotomy and microsurgical clipping of intracranial aneurysms with ICG for 2 years. Patient characteristics, presentation details, operative reports, and pre- and postclipping angiographic images were reviewed to determine the adequacy of the clipping. Results Forty-seven patients underwent clipping with ICG and postoperative DSA: 57 aneurysms were clipped; 23 patients (48.9%) presented with subarachnoid hemorrhage. Nine aneurysms demonstrated a residual on DSA not identified on ICG (residual sizes ranged from 0.5 to 4.3 mm; average size: 1.8 mm). Postoperative DSA demonstrated no branch occlusions. Conclusion Intraoperative ICG is useful in the clipping of intracranial aneurysms to ensure a gross patency of branch vessels; however, the presence of residual aneurysms and subtle changes in flow in branch vessels is best seen by DSA. This has important clinical implications with regard to follow-up imaging and surgical/endovascular management. PMID:26279659

Duplex Ultrasonography Has Limited Utility in Detection of Postoperative DVT After Primary Total Joint Arthroplasty.

Duplex ultrasound is routinely used to evaluate suspected deep venous thrombosis after total joint arthroplasty. When there is a clinical suspicion for a pulmonary embolism, a chest angiogram (chest CTA) is concomitantly obtained. Two questions were addressed: First, for the population of patients who receive duplex ultrasound after total joint arthroplasty, what is the rate of positive results? Second, for these patients, how many of these also undergo chest CTA for clinical suspicion of pulmonary embolus and how many of these tests are positive? Furthermore, what is the correlation between duplex ultrasound results and chest CTA results? A retrospective chart review was conducted of total joint replacement patients in 2011 at a single institution. Inclusion criteria were adult patients who underwent a postoperative duplex ultrasonography for clinical suspicion of deep venous thrombosis (DVT). Demographic data, result of duplex scan, clinical indications for obtaining the duplex scan, and DVT prophylaxis used were recorded. Additionally, if a chest CTA was obtained for clinical suspicion for pulmonary embolus, results and clinical indication for obtaining the test were recorded. The rate of positive results for duplex ultrasonography and chest CTA was computed and correlated based on clinical indications. Two hundred ninety-five patients underwent duplex ultrasonography of which only 0.7% were positive for a DVT. One hundred three patients underwent a chest CTA for clinical suspicion of a pulmonary embolism (PE) of which 26 revealed a pulmonary embolus, none of which had a positive duplex ultrasound. Postoperative duplex scans have a low rate of positive results. A substantial number of patients with negative duplex results subsequently underwent chest CTA for clinical suspicion for which a pulmonary embolus was found, presumably resulting from a DVT despite negative duplex ultrasound result. A negative duplex ultrasonography should not rule out the presence of a DVT which can embolize to the lungs and thus should not preclude further workup when clinical suspicion exists for a pulmonary embolus.

Background Advancement in endovascular techniques has led to rapid growth in endovascular revascularization, and it has emerged as a treatment for critical limb ischemia (CLI). Clinical effectiveness of revascularization has been frequently judged by vessel patency and limb salvage, but there is paucity of reports on outcomes of the wound. We present a retrospective analysis of immediate angiographic and 3-month clinical outcome of patients who underwent endovascular reconstruction of popliteal and infrapopliteal arteries for CLI. Methods All patients who underwent endovascular reconstruction of popliteal and/or infrapopliteal arteries for CLI and >70% stenosis on digital subtraction angiography between March 2010 and November 2014 and had a clinical follow-up of at least 3 months were selected for analysis. Results 34 patients underwent endovascular reconstruction. 9 patients (26%) underwent only POBA and remaining 25 (74%) underwent additional stenting. 13 patients (38%) had multiple segmental revascularization. 24 patients (71%) had successful vessel recanalization. Linear flow to foot in at least one artery could be achieved in 20 patients (59%) post revascularization. Successful wound healing occurred in 11 (35%) patients with an additional 7 (21%) patients showing clinical improvement in their wounds. Limb salvage was achieved in 33 patients (97%) at 3-month follow-up. Conclusion Endovascular revascularization of popliteal and infrapopliteal arteries is a feasible, safe, and effective procedure for the treatment of CLI. Normal inflow and outflow with at least one of the three infrapopliteal vessels being patent is essential for adequate healing of chronic ulcers and prevention of major amputation. PMID:26896272

We have previously reported a hybrid procedure that uses a combination of laparoscopic mobilization of the liver and subsequent hepatectomy under direct vision in living donor liver transplantation (LDLT). We present the details of this hybrid procedure and the outcomes of the procedure. Between January 1997 and August 2014, 204 LDLTs were performed at Nagasaki University Hospital. Among them, 67 recent donors underwent hybrid donor hepatectomy. Forty-one donors underwent left hemihepatectomy, 25 underwent right hemihepatectomy, and 1 underwent posterior sectionectomy. First, an 8-cm subxiphoid midline incision was made; laparoscopic mobilization of the liver was then achieved with a hand-assist through the midline incision under the pneumoperitoneum. Thereafter, the incision was extended up to 12 cm for the right lobe and posterior sector graft and 10 cm left lobe graft procurement. Under direct vision, parenchymal transection was performed by means of the liver-hanging maneuver. The hybrid procedure for LDLT recipients was indicated only for selected cases with atrophic liver cirrhosis without a history of upper abdominal surgery, significant retroperitoneal collateral vessels, or hypertrophic change of the liver (n = 29). For total hepatectomy and splenectomy, the midline incision was sufficiently extended. All of the hybrid donor hepatectomies were completed without an extra subcostal incision. No significant differences were observed in the blood loss or length of the operation compared with conventional open procedures. All of the donors have returned to their preoperative activity level, with fewer wound-related complaints compared with those treated with the use of the conventional open procedure. In recipients treated with the hybrid procedure, no clinically relevant drawbacks were observed compared with the recipients treated with a regular Mercedes-Benz-type incision. Our hybrid procedure was safely conducted with the same quality as the conventional open procedure in both LDLT donors and recipients. Copyright © 2015 Elsevier Inc. All rights reserved.

Wheelchair athletes are susceptible to injuries related to overuse of the shoulder, in particular shoulder impingement syndrome. The present study examined the relationship of shoulder pain to demographic details, isokinetic strength and muscle balance in 8 elite quadriplegic rugby players. Demographic data were collected using personal interviews and each subject was clinically examined for signs of impingement syndrome by a physician. In addition each subject underwent bilateral isokinetic strength testing of the shoulder at 60 and 180 deg/s for abduction/adduction and internal/external rotation. A series of step-wise multiple discriminant analysis successfully predicted clinical symptoms from demographic, muscular strength and balance data. In particular, there was a significant deficit in adductor strength and this was related to shoulder pain and wasting of the scapular muscles. This strength deficit may be due to the high level of spinal lesions in the quadriplegic population. The level of spinal lesion may contribute to the aetiology of shoulder pathology in quadriplegia, and differentiate it from that observed in able-bodied athletes who exhibit weak abductors.

Previous examination of whole-body muscle involvement in Pompe disease has been limited to physical examination and/or qualitative magnetic resonance imaging (MRI). In this study we assess the feasibility of quantitative proton-density fat-fraction (PDFF) whole-body MRI in late-onset Pompe disease (LOPD) and compare the results with manual muscle testing. Seven LOPD patients and 11 disease-free controls underwent whole-body PDFF MRI. Quantitative MR muscle group assessments were compared with physical testing of muscle groups. The 95% upper limits of confidence intervals for muscle groups were 4.9-12.6% in controls and 6.8-76.4% in LOPD patients. LOPD patients showed severe and consistent tongue and axial muscle group involvement, with less marked involvement of peripheral musculature. MRI was more sensitive than physical examination for detection of abnormality in multiple muscle groups. This integrated, quantitative approach to muscle assessment provides more detailed data than physical examination and may have clinical utility for monitoring disease progression and treatment response. © 2014 Wiley Periodicals, Inc.

The Mysore Parthenon Birth Cohort was established to examine the long-term effects of maternal glucose tolerance and nutritional status on cardiovascular disease risk factors in the offspring. During 1997–98, 830 of 1233 women recruited from the antenatal clinics of the Holdsworth Memorial Hospital (HMH), Mysore, India, underwent an oral glucose tolerance test. Of these, 667 women delivered live babies at HMH. Four babies with major congenital anomalies were excluded, and the remaining 663 were included for further follow-up. The babies had detailed anthropometry at birth and at 6–12-monthly intervals subsequently. Detailed cardiovascular investigations were done at ages 5, 9.5 and 13.5 years in the children, and in the parents at the 5-year and 9.5-year follow-ups. This ongoing study provides extensive data on serial anthropometry and body composition, physiological and biochemical measures, dietary intake, nutritional status, physical activity measures, stress reactivity measures and cognitive function, and socio-demographic parameters for the offspring. Data on anthropometry, cardiovascular risk factors and nutritional status are available for mothers during pregnancy. Anthropometry and risk factor measures are available for both parents at follow-up. PMID:24609067

To explore the characteristics of congenital vaginal atresia, further improve its classification, and therefore help the clinical diagnosis and treatment of congenital vaginal atresia. This was a retrospective study of 67 patients with congenital vaginal atresia (from March 1984 to March 2015). Clinical and surgical characteristics were analyzed. For lower vaginal atresia, 25 patients successfully underwent vaginoplasty at the lower portion of the vagina. For complete vagina atresia, 25 patients with type i cervical atresia were treated with artificial vaginoplasty+tracheloplasty, and all showed no dysmenorrhea within six months after surgery. Four patients with type ii cervical atresia and two patients with type iii cervical atresia successfully underwent hysterectomy+artificialvaginoplasty. Two patients with type iv cervical atresia underwent combined abdominoperineal artificial vaginoplasty+tracheloplasty. One patient with upper vaginal atresia successfully underwent hysterectomy via the narrow segment of the cervix. Three patients with top vaginal atresia had no dysmenorrhea after transvaginaltracheloplasty. This study suggests two new categories of vaginal atresia (upper vaginal atresia and top vaginal atresia), which could be used as a reference for treatment of this condition. Appropriate treatments were performed using a personalized approach and satisfactory results were achieved. Copyright © 2017. Published by Elsevier B.V.

It is essential to identify hypopituitarism in children with optic nerve hypoplasia (ONH) because they are at risk for developmental delay, seizures, or death. The purpose of this study is to determine the reliability of neurohypophyseal abnormalities on magnetic resonance imaging (MRI) for the detection of hypopituitarism in children with ONH. Cross-sectional study. One hundred one children with clinical ONH who underwent MRI of the brain and orbits and a detailed pediatric endocrinologic evaluation. Magnetic resonance imaging studies were performed on 1.5-Tesla scanners. The imaging protocol included sagittal T1-weighted images, axial fast fluid-attenuated inversion-recovery/T2-weighted images, and diffusion-weighted images of the brain. Orbital imaging included fat-saturated axial and coronal images and high-resolution axial T2-weighted images. The MRI studies were reviewed by 2 pediatric neuroradiologists for optic nerve hypoplasia, absent or ectopic posterior pituitary, absent pituitary infundibulum, absent septum pellucidum, migration anomalies, and hemispheric injury. Medical records were reviewed for clinical examination findings and endocrinologic status. All patients underwent a clinical evaluation by a pediatric endocrinologist and a standardized panel of serologic testing that included serum insulin-like growth factor-1, insulin-like growth factor binding protein-3, prolactin, cortisol, adrenocorticotropic hormone, thyroid-stimulating hormone, and free thyroxine levels. Radiologists were masked to patients' endocrinologic status and funduscopic findings. Sensitivity and specificity of MRI findings for the detection of hypopituitarism. Neurohypophyseal abnormalities, including absent pituitary infundibulum, ectopic posterior pituitary bright spot, and absent posterior pituitary bright spot, occurred in 33 children. Magnetic resonance imaging disclosed neurohypophyseal abnormalities in 27 of the 28 children with hypopituitarism (sensitivity, 96%). A normal neurohypophysis occurred in 67 of 73 children with normal endocrinologic function (specificity, 92%). Neurohypophyseal abnormalities on MRI are sensitive and specific indicators of hypopituitarism in children with ONH. Copyright © 2014 American Academy of Ophthalmology. Published by Elsevier Inc.

In this prospective cohort study, we investigated the prevalence of diabetic peripheral neuropathy at baseline and after five years of follow-up in children and adolescents with type 1 diabetes mellitus using both measurements of nerve conduction velocity and clinical neurological examination. A total of 38 patients who underwent insulin pump or intensive insulin therapy were included. The subjects averaged 12.6 ± 2.4 years of age and their diabetes duration averaged 5.6 ± 3.2 years. All patients underwent a detailed physical, neurological, and electrophysiological examination, as well as laboratory testing at their annual checkup. At baseline, the prevalence of diabetic peripheral neuropathy diagnosed using neurological examination was 13.2%, whereas nerve conduction velocity testing revealed diabetic peripheral neuropathy in 31.6%, highlighting a high prevalence of subclinical diabetic peripheral neuropathy. During follow-up, there was a strong increase in the prevalence of clinically diagnosed diabetic peripheral neuropathy, which reached 34.2% (P = 0.039) after five years; the proportion of patients with subclinical diabetic peripheral neuropathy even reached 63.2% (P = 0.002). The most significant changes in electrophysiological parameters were observed in the tibial sensory nerve (P = 0.001). The prevalence of diabetic peripheral neuropathy in children and adolescents with type 1 diabetes mellitus was high, and there was a rapid increase in the prevalence of diabetic peripheral neuropathy during a five-year follow-up interval. Importantly, our data show that a mere clinical evaluation is not sensitive enough to diagnose diabetic peripheral neuropathy in these patients. Nerve conduction velocity measurement, which is regarded as the gold standard for the assessment of diabetic peripheral neuropathy, should be applied more broadly. Copyright © 2017 Elsevier Inc.

There are few studies on Modic changes of the cervical spine in patients suffering from whiplash. This study compared Modic changes seen in whiplash patients 10 years after the injury with those observed in asymptomatic volunteers. This is a follow-up study of 133 patients who suffered whiplash injuries in 1994-1996 and underwent MRI with a superconductive imager (63 men, 70 women, mean age 49.6±15.3 years, mean follow-up 11.4 years). In addition, 223 healthy volunteers who underwent MRI during the same period were included as controls (123 men, 100 women, mean age 50.5±15.0 years, mean follow-up 11.6 years). All participants underwent follow-up MRI. We examined all participants for Modic changes, and investigated relationships between Modic changes and clinical symptoms or potentially related factors. Modic changes were observed in 4 patients (3%) and at 7 intervertebral levels in the initial study, and in 17 patients (12.8%) and at 30 intervertebral levels at the follow-up. Modic Type 2 changes were the most prevalent in the whiplash patients in both the initial and follow-up studies. There was no significant difference in the percentage of whiplash patients versus control subjects with positive Modic changes, either at the initial study or at follow-up. Modic changes were not related to clinical symptoms present at follow-up, but were associated with preexisting disc degeneration. There was no association between Modic changes and the details of the car accident that caused the injury. While Modic changes became more common in whiplash patients in the 10-year period after the accident, they occurred with a similar frequency in control subjects. We did not find any association between Modic changes and the nature of the car accident in which the whiplash occurred. Modic changes found in whiplash patients may be a result of the physiological ageing process rather than pathological findings relating to the whiplash injury. Copyright © 2012 Elsevier Ltd.

To identify nailfold videocapillaroscopic features and other clinical risk factors for new digital ulcers (DUs) during a 6-month period in patients with systemic sclerosis (SSc). In this multicenter, prospective, observational cohort study, the videoCAPillaroscopy (CAP) study, we evaluated 623 patients with SSc from 59 centers (14 countries). Patients were stratified into 2 groups: a DU history group and a no DU history group. At enrollment, patients underwent detailed nailfold videocapillaroscopic evaluation and assessment of demographic characteristics, DU status, and clinical and SSc characteristics. Risk factors for developing new DUs were assessed using univariable and multivariable logistic regression (MLR) analyses. Of the 468 patients in the DU history group (mean ± SD age 54.0 ± 13.7 years), 79.5% were female, 59.8% had limited cutaneous SSc, and 22% developed a new DU during follow-up. The strongest risk factors for new DUs identified by MLR in the DU history group included the mean number of capillaries per millimeter in the middle finger of the dominant hand, the number of DUs (categorized as 0, 1, 2, or ≥3), and the presence of critical digital ischemia. The receiver operating characteristic (ROC) of the area under the curve (AUC) of the final MLR model was 0.738 (95% confidence interval [95% CI] 0.681-0.795). Internal validation through bootstrap generated a ROC AUC of 0.633 (95% CI 0.510-0.756). This international prospective study, which included detailed nailfold videocapillaroscopic evaluation and extensive clinical characterization of patients with SSc, identified the mean number of capillaries per millimeter in the middle finger of the dominant hand, the number of DUs at enrollment, and the presence of critical digital ischemia at enrollment as risk factors for the development of new DUs. © 2016, American College of Rheumatology.

Patients with malformations of cortical development (MCD) present with a wide spectrum of clinical manifestations ranging from asymptomatic cases to those with epilepsy and neurodevelopmental problems. Thorough clinical delineation of patients with MCD may provide clues for future phenotype-genotype correlation studies. We studied clinical features of patients with MCD, including developmental risk factors and family history. We evaluated 10 patients with MCD at Hacettepe University Children's Hospital, Department of Pediatric Neurology. All patients underwent neurological evaluation with detailed medical and family history, and neuropsychological evaluation. Routine EEG and MRI were obtained. The patients were between 1 month and 19 years of age (mean: 6.1 +/- 4.4 years). Fifty-four patients were diagnosed with polymicrogyria (PMG), 23 patients with lissencephaly, 12 patients with schizencephaly, and 12 patients with heterotopia. Parents were relatives in 31.7% of the cases; consanguinity was most common in patients with lissencephaly and other MCDs with diffuse/bilateral involvement. Initial clinical presentation was seizures in 61.4% of the cases, developmental delays in 12.9%, and microcephaly in 9.9%. Neurological evaluation revealed most severe abnormalities in patients with lissencephaly, and relatively better outcome in patients with heterotopias. Cognitive functions were better in patients with heterotopias compared to other groups. Overall, 71.3% of patients ha epilepsy. In conclusion, initial presentation and clinical course of patients with MCD are variable and seem to be correlated with the extent of cortical involvement. Epilepsy and mental retardation are the most common problems. The most severe clinical outcome was seen in patients with lissencephaly.

Subacute sclerosing panencephalitis is a devastating neurodegenerative disease with a characteristic clinical course. Atypical presentations may be seen in 10% of the cases. To describe the atypical clinical and radiological features of SSPE in a child form endemic country. A 5-year-old boy presented with acute-onset cerebellar ataxia without associated encephalopathy, focal motor deficits, seizures or cognitive decline. He had varicella-like illness with vesicular, itchy truncal rash erupting one month prior to the onset of these symptoms. He underwent detailed neurological assessment, relevant laboratory and radiological investigations. Neuroimaging revealed peculiar brain stem lesions involving the pons and cerebellum suggestive of demyelination. With a presumptive diagnosis of clinically isolated syndrome of demyelination, he was administered pulse methylprednisolone (30 mg/kg/day for 5 days). Four weeks later he developed myoclonic jerks. Electroencephalogram showed characteristic periodic complexes time-locked with myoclonus. CSF and serum anti-measles antibody titres were elevated (1:625). Our report highlights that subacute sclerosing panencephalitis can present atypically as isolated acute cerebellar ataxia and peculiar involvement of longitudinal and sparing of transverse pontine fibres. The predominant brainstem abnormalities in the clinical setting may mimick acute demyelinating syndrome. Hence, it is important to recognize these features of subacute sclerosing panencephalitis in children, especially in the endemic countries. Copyright © 2016 European Paediatric Neurology Society.

Isolated left ventricular noncompaction (ILVNC) is a rare congenital cardiomyopathy characterized by numerous excessive trabeculations and deep intertrabecular recesses. To date, the clinical features and genetic causes of ILVNC remain unclear. Here, we report the clinical presentation and genetic analysis of a five generation Chinese family with ILVNC. For this study, 21 living family members were recruited. Each individual underwent a detailed clinical examination for ILVNC. Peripheral blood samples were collected for direct gene sequencing to determine any mutations in the known disease-causing genes of ILVNC, which include the genes TAZ, DTNA, LDB3, LMNA and FKBP12. Classic echocardiographic presentation of ILVNC was identified in the proband who had his first onset of heart failure at age 52. His 28-year-old son and 26-year-old daughter showed similar heart anomalies as their father. Although they had no symptoms to date, depressed ventricular systolic function was noted in both of them. Pedigree analysis suggested an autosomal domain mode of inheritance. DNA sequencing found no mutation in the known disease-causing genes of ILVNC. Interestingly, two other members of the family, the proband's wife (also his first cousin) and her sister had classic echocardiographic presentation of hypertrophic cardiomyopathy (HCM). A single Chinese family with ILVNC associated with HCM is reported; no mutations in TAZ, DTNA, LDB3, LMNA and FKBP12 was found.

As status of rheumatoid arthritis (RA) is highly affected by environmental factors, a catastrophic disaster may also affect RA activity. Herein we conducted a retrospective cohort study in the disaster area of the 2011 triple disaster in Fukushima, Japan: an earthquake, tsunamis and a nuclear accident. Clinical records of RA patients who attended a hospital near the Fukushima Daiichi Nuclear Power Plant were collected. For those who underwent whole-body counter testing, internal radiation exposure levels were also collected. As clinical parameters may fluctuate in the absence of a disaster, changes in values before and after the disaster were also compared. Logistic regression was conducted to identify factors affecting RA status. Fifty-three patients (average age, 64.2 years; females, 83%; average disease duration, 15.7 years) were included in the study. Five patients lived within the no-entry zone, 37 evacuated immediately after the disaster, and four temporarily stopped RA treatment. The proportions of patients who showed worsened tender joint counts, swollen joint counts and rheumatoid factor values were significantly higher after the disaster compared to those before. Among the 16 patients who underwent whole-body counter testing, only one showed a detectable, but negligible, radioactive cesium level. Use of methotrexate was identified as a possible preventive factor for RA exacerbation in this setting. This is the first study to analyze detailed profiles of RA patients after a disaster. As methotrexate may prevent disease exacerbation, continuity of care for this common chronic disease should be considered in disaster settings. © 2018 Asia Pacific League of Associations for Rheumatology and John Wiley & Sons Australia, Ltd.

The objective of our study was to investigate the clinical value of diagnostic lymphangiography followed by sequential CT examinations in patients with idiopathic chyluria. Thirty-six patients with idiopathic chyluria underwent unipedal diagnostic lymphangiography and then underwent sequential CT examinations. The examinations were reviewed separately by two radiologists. Abnormal distribution of contrast medium, lymphourinary leakages, and retrograde flow were noted, and the range and distribution of lymphatic vessel lesions were recorded. The stage of idiopathic chyluria based on CT findings and the stage based on clinical findings were compared. Therapeutic management and follow-up were recorded. Statistical analyses were performed. Compared with CT studies performed after lymphangiography, diagnostic lymphangiography showed a unique capability to depict lymphourinary leakages in three patients. Lymphourinary fistulas and abnormal dilated lymphatic vessels were found in and around kidney in all patients. CT depicted retrograde flow of lymph fluid in 47.2% of patients. The consistency in staging chyluria based on CT findings and clinical findings was fair (κ = 0.455). Twenty-nine patients underwent conservative therapy, and seven underwent surgery. Surgical therapy was superior to conservative management (no recurrence, 85.7% of patients who underwent surgery vs 62.1% of patients who underwent conservative therapy; p = 0.025). From assessing the drainage of contrast medium on unipedal diagnostic lymphangiography and the redistribution of contrast medium on sequential CT examinations, it is possible to detect the existence of lymphourinary fistulas, the precise location of lymphatic anomalies, the distribution of collateral lymphatic vessels, and hydrodynamic pressure abnormality in the lymph circulation in patients with idiopathic chyluria. CT staging of chyluria provides additional information that can be used to guide therapeutic management.

Dandy-Walker syndrome (DWS) is characterized by perfect or partial defect of the cerebellum vermis and cystic dilatation of the posterior fossa communicating with the fourth ventricle. Common clinical signs are mental retardation, cerebellar ataxia, and those of increased intracranial pressure (ICP). Associated congenital anomalies are craniofacial, cardiac, renal, and skeletal abnormalities. We experienced a case of intravenous sedation and six times of "the same day" general anesthesia for a school-aged boy (10-13 years old) with DWS and hypodentinogenesis. The patient underwent an examination and dental treatments. We had to pay attention to airway management tracheal tube selection and control of ICP. In addition, we should prevent tooth injuries through mishaps during tracheal intubations, since all-tooth-hypoplasia with fragile dental crowns was strongly suggested in this case. Detailed postoperative care is also required for general anesthesia afflicted with DWS.

Primary squamous cell carcinoma (SCC) of ampulla has seldom been reported. However, metastatic SCC to ampulla of Vater is well known. We report a case of primary SCC of ampulla of Vater coexistent with well-differentiated adenocarcinoma of the distal pancreatic duct. A 50-year-old female presented with evidence of obstructive jaundice. Endoscopic retrograde cholangio-pancreatography revealed bulging papilla with ulcero-infiltrative growth at the ampulla of Vater. An initial endoscopic biopsy of the ampullary mass showed a well-differentiated SCC. The patient underwent Whipple's operation. Thorough sampling of the dilated portion of the pancreatic duct showed presence of well-differentiated adenocarcinoma of the distal pancreatic duct. Immunohistochemical study with synaptophysin and chromogranin was done with negative result, ruling out neuroendocrine differentiation. Also, a detailed clinical, endoscopic and radiological examination was carried out, that excluded the presence of primary SCC elsewhere. PMID:22064341

The use of empirically supported treatment (EST) has been shown to enhance treatment outcome. The purpose of this case study was to suggest that ESTs further encourage effective reconceptualisation and the ongoing delivery of effective treatment, especially in the case of complex or atypical presentations or response to treatment. This report describes the case of an adolescent girl who underwent Maudsley family-based treatment for anorexia nervosa (AN) for a period of 12 months. Atypical response lead to an understanding of her presentation as representing a primary conversion disorder, within which AN symptoms were conceptualised as another somatic conversion of emotional distress. The report details her clinical presentation and management over the course of her illness. The case offers an important opportunity to explore the central role of the use of ESTs in guiding effective treatment delivery.

A 53-year-old female developed epigastric discomfort and back pain in 2007. Diagnostic imaging studies demonstrated a soft tissue tumor with heterogeneous enhancement in the anterior mediastinum and multiple nodules in the right lung. She underwent expanded thymectomy with subtotal resection of the right lung. The pathological diagnosis was primary thymic mucosa-associated lymphoid tissue (MALT) lymphoma. The patient complained of ocular discomfort, oral dryness and continuous nasal bleeding in 2007. Detailed examination led to a diagnosis of Sjögren syndrome and acquired von Willebrand syndrome. Rituximab treatment for residual disease achieved not only a reduction of the lung MALT lymphoma but also clinical and hematological remission of both syndromes. This is, to our knowledge, the first reported case of primary thymic MALT lymphoma accompanied by Sjögren and acquired von Willebrand syndromes.

Abstract Clinically significant sellar cysts unrelated to pituitary adenomas are uncommon. Intracranial cholesteatomas are also rare and are most common in the middle ear and mastoid region. We report an even rarer case of cholesteatoma in the sellar region—a challenging diagnosis guided by clinical presentations, radiological signs, and biopsy, aiming at emphasize the importance of considering cholesteatoma when making differential diagnoses of sellar lesions. We present a case of cholesteatoma in the sellar region in a 56-year-old man with hypopituitarism, diabetes insipidus, and cystic imaging findings. It was difficult to make an accurate diagnosis before surgery. We present detailed analysis of the patient's disease course and review pertinent literature. The patient underwent a surgical exploration and tumor resection through a transsphenoidal approach. Pathologic results revealed a cholesteatoma. The patient's symptoms improved a lot after surgery, and the postoperative period was uneventful. Taken together, the lesion's imaging appearance, pathological characteristics, and clinical features were all unique features that lead to a diagnosis of cholesteatoma. As we did not see such reports by Pubmed and EMBASE, we believe this is the first reported case of sellar cholesteatoma presenting in this manner. This article emphasized that cholesteatomas, although rare, should be considered part of the differential diagnosis of sellar lesions. PMID:26962793

[Clinical decision to perform cranial computed tomography in children with non-severe head injury].

Franco-Koehrlen, Celine Alicia; Iglesias-Leboreiro, José; Bernárdez-Zapata, Isabel; Rendón-Macías, Mario Enrique

The main goal of this article was to evaluate if the decision to perform cranial computed tomography (CT) in children with minor head injury is determined by the presence or absence of the physician during assessment in the emergency room. Clinical files of 92 patients from 8 months to 4 years of age were selected. Those children were evaluated at the emergency department of the Spanish Hospital of Mexico due to non-severe traumatic brain injury. Glasgow Coma Scale (GCS) score was determined in all patients. Groups of patients were compared: 1) patients having CT, 2) patients with a physician who attended the initial assessment, 3) patients whose attending physician did not arrive to assess the patient and 4) patients assessed by the emergency room staff. 38% of patients with non-severe brain injury underwent CT, 8.6% had a brain injury visible on the CT. Moderate intensity impacts were greater in patients with CT. Regarding the ECG, it was found that most children scored 15 points (p=0.03). In patients without a physician, a greater trend was demonstrated for performing CT. Patients with minor head injury but without neurological signs should undergo a detailed clinical evaluation in order to avoid unwarranted CT. Copyright © 2015.

The utility of obtaining a routine cystogram after the repair of intraperitoneal bladder disruption before urethral catheter removal is unknown. This study was designed to examine whether follow-up cystogram evaluation after traumatic bladder disruption affected the clinical management of these injuries. We hypothesized that routine cystograms, after operative repair of intraperitoneal bladder disruptions, provide no clinically useful information and may be eliminated in the management of these injuries. Our prospectively collected trauma database was retrospectively reviewed for all ICD-9 867.0 and 867.1 coded bladder injuries over a 6-year period ending in June 2004. Demographics, clinical injury data, detailed operative records, and imaging studies were reviewed for each patient. Bladder injuries were categorized as intraperitoneal (IP) or extraperitoneal (EP) bladder disruptions based on imaging results and operative exploration. Patients with IP injuries were further subdivided into those with "simple" dome disruptions or through-and-through penetrating injuries and "complex" injuries involving the trigone or ureter reimplantation. All patients sustaining isolated ureteric or urethral injury were excluded from further analysis. In all, 20,647 trauma patients were screened for bladder injury. Out of this group, there were 50 IP (47 simple, 3 complex) and 37 EP injuries available for analysis. All IP injuries underwent operative repair. Eight of the IP injuries (all simple) had no postoperative cystogram and all were doing well at 1- to 4-week follow-up. The remaining 42 patients underwent a postoperative cystogram at 15.3 +/- 7.3 days (range 7 to 36 days). All simple IP injuries had a negative postoperative cystogram. The only positive study was in one of the three complex IP injuries. In the EP group, 21.6% had positive cystograms requiring further follow-up and intervention. Patients sustaining extraperitoneal and complex intraperitoneal bladder disruptions require routine cystogram follow-up. In those patients undergoing repair of a simple intraperitoneal bladder disruption, however, routine follow-up cystograms did not affect clinical management. Further prospective evaluation to determine the optimal timing of catheter removal in this patient population is warranted.

While the treatment pathway in response to benign or malignant prostate biopsies is well established, there is uncertainty regarding the risk of subsequently diagnosing prostate cancer when an initial diagnosis of prostate atypia is made. As such, we investigated the likelihood of a repeat biopsy diagnosing prostate cancer (PCa) in patients in which an initial biopsy diagnosed prostate atypia. We reviewed our prospectively maintained prostate biopsy database to identify patients who underwent a repeat prostate biopsy within one year of atypia (atypical small acinar proliferation; ASAP) diagnosis between November 1987 and March 2011. Patients with a history of PCa were excluded. Chart review identified patients who underwent radical prostatectomy (RP), radiotherapy (RT), or active surveillance (AS). For some analyses, patients were divided into two subgroups based on their date of service. Ten thousand seven hundred and twenty patients underwent 13,595 biopsies during November 1987-March 2011. Five hundred and sixty seven patients (5.3%) had ASAP on initial biopsy, and 287 (50.1%) of these patients underwent a repeat biopsy within one year. Of these, 122 (42.5%) were negative, 44 (15.3%) had atypia, 19 (6.6%) had prostatic intraepithelial neoplasia, and 102 (35.6%) contained PCa. Using modified Epstein's criteria, 27/53 (51%) patients with PCa on repeat biopsy were determined to have clinically significant tumors. 37 (36.3%) proceeded to RP, 25 (24.5%) underwent RT, and 40 (39.2%) received no immediate treatment. In patients who underwent surgery, Gleason grade on final pathology was upgraded in 11 (35.5%), and downgraded 1 (3.2%) patient. ASAP on initial biopsy was associated with a significant risk of PCa on repeat biopsy in patients who subsequently underwent definitive local therapy. Patients with ASAP should be counseled on the probability of harboring both clinically significant and insignificant prostate cancer. © 2015 Wiley Periodicals, Inc.

To evaluate the prevalence of cystic macular lesions in patients with Usher II syndrome. All Usher type II patients seen in the inherited eye disease clinic at the University of Illinois at Chicago between January 2002 and December 2007 were included (n=76). Each participating patient underwent a detailed clinical examination, including best-corrected visual acuity, slit-lamp biomicroscopy and dilated fundus examination. The presence of cystoid lesions was determined by optical coherence tomography (OCT), fundus fluorescein angiogram (FFA), fundus photographs and/or clinical examination. A cystic-appearing macular change was observed in at least one eye in 19 out of the 76 patients (25%), 13 on the basis of OCT, five using FFA (two solely with the use of FFA and three based on clinical notes and FFA findings) and one based solely on clinical notes. Of the 18 patients with CME, determined by OCT or FFA, five (27.8%) showed either a funduscopically normal-appearing macula (n=4) or an atrophic appearing macular change (n=1). One-fourth of our total cohort of Usher II patients had cystic macular lesions. Moreover, a funduscopically normal-appearing macula was observed in 22% (n=4) of our 18 patients with cystic-appearing macular lesions on OCT and/or FFA testing. On the basis of the reasonably high prevalence of cystic macular lesions in our cohort, it would seem prudent to evaluate Usher II patients for the presence of cystoid macular oedema.

To assess the efficacy of radiographer-performed ultrasound examination as a routine investigative procedure in a urological out-patient clinic. A total of 151 patients attending a District General Hospital Urological Out-patient Department underwent an ultrasound examination in the clinic. Diagnosis by ultrasound was achieved in 93% of patients. The remaining patients underwent further investigations. Two (1%) patients with normal scans had small bladder tumours. Subsequent intravenous urography in these individuals showed normal upper tracts. Abdominal and pelvic ultrasound examination performed in the urological out-patient clinic on unprepared patients was the only investigation necessary for evaluation of common problems such as non-specific urinary symptoms, recurrent urinary tract infections and bladder outlet obstruction.

Neurosurgical disorders are rare during pregnancy and challenge the anesthesiologist with conflicting anesthetic considerations and little evidence to guide decision-making. Our objective was to review the anesthetic management of pregnant patients undergoing intracranial neurosurgery at our institution and to describe the perioperative complications and outcomes. We used our institutional Discharge Abstract Database to identify patients assigned both neurological and obstetrical International Classification of Disease 10-A codes between April 1, 2001 and March 1, 2012. Pregnant patients who underwent intracranial neurosurgical procedures underwent a detailed chart review to extract demographic data and details about their anesthetic management and outcome. Nine patients underwent full chart review with a median age of 28 (range, 17 to 35) years and a gestational age of 23 (range, 7 to 30) weeks. Patients underwent a craniotomy for vascular lesions (4), neoplasms (3), and traumatic brain injuries (2). One patient was hyperventilated (PaCO2 28 mmHg), and mannitol and furosemide were used in 6 and 3 patients, respectively, without complication. Maternal neurological outcomes were good in 5 patients (Glasgow Outcome Scale of >3), poor in 3 patients (Glasgow Outcome Scale 3), and 1 patient died. Fetal outcomes were good in 5 patients and poor in 4 patients (1 therapeutic abortion, 3 intrauterine fetal demises). All cases of fetal distress or demise were either remote or occurred before the anesthetic management. Pregnant patients undergoing neurosurgery experience a high rate of morbidity and mortality. There were no adverse outcomes directly attributed to the use of osmotic diuretics and hyperventilation in our series.

Clinical utility and cost-effectiveness of carotid duplex examination prior to cardiac surgery have been questioned by the multidisciplinary committee creating the 2012 Appropriate Use Criteria for Peripheral Vascular Laboratory Testing. We report the clinical outcomes and postoperative neurologic symptoms in patients who underwent carotid duplex ultrasound prior to open heart surgery at a tertiary institution. Using the combined databases from our clinical vascular laboratory and the Society of Thoracic Surgery, a retrospective analysis of all patients who underwent carotid duplex ultrasound within 13 months prior to open heart surgery from March 2005 to March 2013 was performed. The outcomes between those who underwent carotid duplex scanning (group A) and those who did not (group B) were compared. Among 3233 patients in the cohort who underwent cardiac surgery, 515 (15.9%) patients underwent a carotid duplex ultrasound preoperatively, and 2718 patients did not (84.1%). Among the patients who underwent carotid screening vs no screening, there was no statistically significant difference in the risk factors of cerebrovascular disease (10.9% vs 12.7%; P = .26), prior stroke (8.2% vs 7.2%; P = .41), and prior transient ischemic attack (2.9% vs 3.3%; P = .24). For those undergoing isolated coronary artery bypass grafting (CABG), 306 (17.8%) of 1723 patients underwent preoperative carotid duplex ultrasound. Among patients who had carotid screening prior to CABG, the incidence of carotid disease was low: 249 (81.4%) had minimal or mild stenosis (<50%); 25 (8.2%) had unilateral moderate stenosis (50%-69%); 10 (3.3%) had bilateral moderate stenosis; 9 (2.9%) had unilateral severe stenosis (70%-99%); 5 (1.6%) had contralateral moderate stenosis; 2 (0.7%) had bilateral severe stenosis; 4 (1.3%) had unilateral occluded with contralateral less than 50% stenosis, 1 (0.3%) had unilateral occluded with contralateral (70%-99%) stenosis; and 1 had bilateral occluded carotid arteries. Primary outcomes of patients who underwent isolated CABG showed no difference in the perioperative mortality (2.9% vs 4.3%; P = .27) and stroke (2.9% vs 2.6%; P = .70) between patients undergoing preoperative duplex scanning and those who did not. Primary outcomes of patients who underwent open heart surgery also showed no difference in the perioperative mortality (5.1% vs 6.9%; P = .14) and stroke (2.6% vs 2.4%; P = .85) between patients undergoing preoperative duplex scanning and those who did not. Operative intervention of severe carotid stenosis prior to isolated CABG occurred in 2 of the 17 patients (11.8%) identified who underwent carotid endarterectomy with CABG. In this study, the correlation between preoperative duplex-documented high-grade carotid stenosis and postoperative stroke was low. Prudent use of preoperative carotid duplex ultrasound should be based on the presence of cerebrovascular symptoms and the type of open heart surgery. Copyright © 2016 Society for Vascular Surgery.

The aim of this article is to report on the importance and challenges of a time-resolved and spatio-temporal analysis of fMRI data from complex cognitive processes and associated disorders using a study on developmental dyscalculia (DD). Participants underwent fMRI while judging the incorrectness of multiplication results, and the data were analyzed using a sequence of methods, each of which progressively provided more a detailed picture of the spatio-temporal aspect of this disease. Healthy subjects and subjects with DD performed alike behaviorally though they exhibited parietal disparities using traditional voxel-based group analyses. Further and more detailed differences, however, surfaced with a time-resolved examination of the neural responses during the experiment. While performing inter-group comparisons, a third group of subjects with dyslexia (DL) but with no arithmetic difficulties was included to test the specificity of the analysis and strengthen the statistical base with overall fifty-eight subjects. Surprisingly, the analysis showed a functional dissimilarity during an initial reading phase for the group of dyslexic but otherwise normal subjects, with respect to controls, even though only numerical digits and no alphabetic characters were presented. Thus our results suggest that time-resolved multi-variate analysis of complex experimental paradigms has the ability to yield powerful new clinical insights about abnormal brain function. Similarly, a detailed compilation of aberrations in the functional cascade may have much greater potential to delineate the core processing problems in mental disorders. PMID:22368322

Purpose. To report the morphological and functional changes associated with a regression of foveoschisis in a patient with X-linked retinoschisis (XLRS). Methods. A 42-year-old man with XLRS underwent genetic analysis and detailed ophthalmic examinations. Functional assessments included best-corrected visual acuity (BCVA), full-field electroretinograms (ERGs), and multifocal ERGs (mfERGs). Morphological assessments included fundus photography, spectral-domain optical coherence tomography (SD-OCT), and adaptive optics (AO) fundus imaging. After the baseline clinical data were obtained, topical dorzolamide was applied to the patient. The patient was followed for 24 months. Results. A reported RS1 gene mutation was found (P203L) in the patient. At the baseline, his decimal BCVA was 0.15 in the right and 0.3 in the left eye. Fundus photographs showed bilateral spoke wheel-appearing maculopathy. SD-OCT confirmed the foveoschisis in the left eye. The AO images of the left eye showed spoke wheel retinal folds, and the folds were thinner than those in fundus photographs. During the follow-up period, the foveal thickness in the SD-OCT images and the number of retinal folds in the AO images were reduced. Conclusions. We have presented the detailed morphological changes of foveoschisis in a patient with XLRS detected by SD-OCT and AO fundus camera. However, the findings do not indicate whether the changes were influenced by topical dorzolamide or the natural history.

Cannabis is a psychotomimetic agent that induces impairment of sensory perception. We present detailed clinical and electrophysiological data of patients with hallucinogen persisting perception disorder (HPPD) after marijuana consumption. A HPPD patient and four heavy cannabis smokers with no visual disturbances (controls) underwent complete ophthalmological examination including psychophysical tests (visual acuity, color vision, visual field, and dark adaptation) and detailed electrophysiological examinations, including extended Ganzfeld ERG, multifocal ERG, and electrooculography (EOG). Furthermore, electrically evoked phosphene thresholds (EPTs) were measured to further evaluate retinal function. Ophthalmological and most electrophysiological examinations were within normal limits for the HPPD patient and for all control subjects. Interestingly, EOG results of the HPPD patient showed a slightly reduced fast oscillation ratio, diminished standing potentials of the slow oscillations, and a light peak within normal range resulting in higher Arden ratios. The EPTs of the patient were reduced, in particular for pulses with long durations (50 ms) causing visual sensations even at lowest possible currents of the neurostimulator. The control subjects did not reveal such alterations. Our findings suggest a direct effect of cannabinoids on the retina and retinal pigment epithelium function, which may be involved in disturbances of the visual function experienced after drug consumption. The observations presented here may contribute to the elucidation of the detailed mechanism. Furthermore, EOG and EPT measurements may be useful tools to demonstrate long-term retinal alterations in cannabis-induced HPPD in patients.

Deficiency of the 5α-reductase 2 enzyme impairs the conversion of testosterone to dihydrotestosterone (DHT) and differentiation of external genitalia, seminal vesicles and prostate in males. The present study describes the phenotype, genotype and gender identity in a large cohort of patients with 5αRD2. All patients underwent detailed clinical evaluation, hormonal profile, karyotyping and molecular analysis of the SRD5A2 gene. The molecular analysis of the SRD5A2 gene showed the presence of mutant alleles in 24 patients. We found 6 novel mutations IVS(1-2) T>C, p.A52T, 188-189insTA, 904-905ins A, p.A12T and p.E57X in our patients. All patients had ambiguous genitalia and the degrees of under-virilization ranged from penoscrotal hypospadias and microphallus to clitoromegaly. The position of gonads was variable in patients with same mutation. All the patients with mutations in the SRD5A2 gene had male gender identity. Those reared as female had gender dysphoria and underwent gender reassignment. Though a specific genotype-phenotype correlation could not be established in our patient but confirming the diagnosis of 5αRD2 with assessment of the SRD5A2 gene may help in appropriate gender assignment. © 2015 American Society of Andrology and European Academy of Andrology.

Role of endoscopy in recalcitrant intraventricular tuberculoma-innovative novel treatment adjunct.

Introduction. Intraventricular tuberculomas are rare entities. To the best of our knowledge, only 14 cases have been reported in English literature. Medical management of cerebral tuberculomas is well accepted. Intraventricular tuberculomas may be recalcitrant for unclear reasons. An effective management protocol for this entity is unclear. To the best of our knowledge, the definitive indication, timing, and possible role of surgery in these lesions have not been discussed in literature. Materials and methods. A 27-year-old nursing professional who was undergoing treatment for miliary tuberculosis at another center presented to us in 2008 with right hemiparesis, deteriorating vision, and progressive decline in consciousness. In addition to antituberculous therapy (ATT), she underwent multiple CSF diversion procedures for the obstructive hydrocephalus secondary to a recalcitrant third ventricular tuberculoma. Finally, she underwent endoscopic decompression of the lesion with a very good clinical response at 1-year follow-up. Discussion. We discuss a patient with recalcitrant intraventricular tuberculoma managed using neuroendoscopy along with the standard antituberculous therapy. We also discuss in detail the technique we utilized for endoscopic management of this lesion. Conclusion. Being a rare entity, a consensus for management of these lesions is not possible, but we have demonstrated that neuroendoscopic management of these rare entities is an option giving the advantage of definitive diagnosis when required, hastening the resolution, and clearing the CSF pathway.

In 2011, the Royal College of Surgeons published Emergency Surgery: Standards for Unscheduled Care in response to variable clinical outcomes for emergency surgery. The purpose of this study was to examine whether different treatment modalities would alter survival. All patients who underwent emergency laparotomy between April 2011 and December 2012 at Warwick Hospital (Warwick, UK) were included retrospectively. Information relating to their demographics; preoperative score; primary pathology; timing of surgery; intraoperative details; and postoperative outcome, including 30-day mortality, were collated for statistical analysis. In total, 91 patients underwent 97 operations. The median age was 64 years (range 50-90, male:female 1:2). Sixty-five percent of cases were obstruction and perforation, and 66% of all operations were performed during office hours. The unadjusted 30-day mortality was 15.4%. Compared with nonsurvivors, survivors had a significantly higher Portsmouth-Physiological and Operative Severity Score for the enUmeration of Mortality and Morbidity score ( P < 0.001), prolonged duration of hypotension and use of inotropes ( P = 0.013), higher volume of colloid use ( P = 0.04), and lower core body temperature ( P < 0.05). Grades of surgeons did not influence mortality. The 30-day mortality rate is comparable to the national standard. Further studies are warranted to determine whether trauma management modalities may be adopted to target high-risk patients who exhibit the lethal triad of hypotension, coagulopathy, and hypothermia.

Intensive treatment including surgery for patients with trisomy 13 (T13) remains controversial. This study aimed to evaluate the safety and efficacy of noncardiac surgical intervention for T13 patients. Medical records of patients with karyotypically confirmed T13 treated in the neonatal intensive care unit in Nagano Children's Hospital from January 2000 to October 2016 were retrospectively reviewed, and data from patients who underwent noncardiac surgery were analyzed. Of the 20 patients with T13, 15 (75%) underwent a total of 31 surgical procedures comprising 15 types, including tracheostomy in 10 patients and gastrostomy in 4. Operative time, anesthesia time, and amount of bleeding are described for the first time in a group of children with T13. All the procedures were completed safely with no anesthetic complications or surgery-related death. The overall rate of postoperative complications was 19.3%. Patients receiving tracheostomy had stable or improved respiratory condition. Six of them were discharged home and were alive at the time of this study. These results suggest at least short-term safety and efficacy of major noncardiac surgical procedures, and long-term efficacy of tracheostomy on survival or respiratory stabilization for home medical care of children with T13. Noncardiac surgical intervention is a reasonable choice for patients with T13. © 2018 Wiley Periodicals, Inc.

[The Kock continent urinary diversion].

The continent ileal reservoir as conceived by Kock produces a low-pressure, high-capacity reservoir with continent and nonrefluxing valves constructed from ileum. From August 1982 through March 1988, 531 patients underwent continent urinary diversion via a Kock reservoir at our institution. Of these, 39 males had a Kock bladder substitution, while the rest underwent cutaneous Kock diversion. Early complications occurred in 16% of all patients, and there was an operative mortality rate of 1.9%. Surgical modifications of nipple fixation, which are discussed in detail in this paper, help to reduce late complications to less than 10%. Patient satisfaction with both procedures remains excellent.

Quality Research in Radiation Oncology (QRRO) has embarked on a new national process survey to provide benchmark data that will allow radiation oncologists to assess the quality of care in their own practices by measuring quality indicators (QIs) and comparing individual with national practice. Investigators at QRRO developed QIs on the basis of nationally recognized, evidence-based guidelines such as those of the National Comprehensive Cancer Network, as well as additional emerging QIs for processes involving rapidly emerging technology. They specifically defined the QIs as clinical performance measures. Published results of the national survey database for patients treated in 1998 and 1999 were reviewed and additional analyses conducted to assess data adequacy to measure compliance with these clinical performance measures. Examples of workup QIs for breast cancer patients showed that 97% underwent diagnostic bilateral mammography, 96% underwent pathology reviews, 83% underwent the determination of estrogen receptor status, 81% underwent the determination of progesterone receptor status, and 31% underwent the determination of human epidermal growth factor receptor 2 status. Compliance with treatment QIs for field recommendations on the basis of nodal findings can be measured. Of patients with prostate cancer, 90% underwent digital rectal examinations, 99% underwent prostate-specific antigen tests, and 99% had their Gleason scores determined. Compliance with QIs on the basis of prognostic group can also be measured. Benchmarking utilization patterns provides a foundation for assessing the appropriateness of cancer care in the future. The QRRO database is a rich data source, and the new survey will provide contemporary benchmark data for these measures.

This single center retrospective study reviews the management and outcomes of 117 consecutive patients with humeral shaft fractures and associated radial nerve palsy (RNP) treated over a 20-year period (1986-2006). A total of 101 fractures were managed conservatively and 16 fractures underwent external fixation for poor bony alignment. Sixteen grade 1 and 2 open fractures underwent wound toileting alone. No patients underwent initial radial nerve exploration or opening of the fracture sites. All patients achieved clinical and radiological bony union at a mean of 8 weeks (range 7-12 weeks). There were no complications or pin tract infections in the operated patients. A total of 111 cases had initial spontaneous RNP recovery at a mean of 6 weeks (range 3-24 weeks) with full RNP recovery at a mean of 17 weeks (range 3-70 weeks) post-injury. Fourteen patients had no clinical/EMG signs of nerve activity at 12 weeks and 6 subsequently failed to regain any radial nerve recovery; 2 had late explorations and the lacerated nerves underwent sural nerve cable neurorraphy; and 4 patients underwent delayed tendon transposition 2-3 years after initial injury, with good/excellent functional outcomes. Humeral fractures with associated RNP may be treated expectantly. With low rates of humeral nonunion, 95% spontaneous nerve recovery in closed fractures and 94% in grade 1 and 2 open fractures, one has the opportunity of waiting. If at 10-12 weeks there are no clinical/EMG signs of recovery, then nerve exploration/secondary reconstruction is indicated. Late tendon transfers may also give good/excellent functional results.

Eggerthella lenta is an emerging pathogen that has been underrecognized due to historical difficulties with phenotypic identification. Until now, its pathogenicity, antimicrobial susceptibility profile, and optimal treatment have been poorly characterized. In this article, we report the largest cohort of patients with E. lenta bacteremia to date and describe in detail their clinical features, microbiologic characteristics, treatment, and outcomes. We identified 33 patients; the median age was 68 years, and there was no gender predominance. Twenty-seven patients (82%) had serious intra-abdominal pathology, often requiring a medical procedure. Of those who received antibiotics (28/33, 85%), the median duration of treatment was 21.5 days. Mortality from all causes was 6% at 7 days, 12% at 30 days, and 33% at 1 year. Of 26 isolates available for further testing, all were identified as E. lenta by both commercially available matrix-assisted laser desorption ionization–time of flight mass spectrometry (MALDI-TOF MS) systems, and none were found to harbor a vanA or vanB gene. Of 23 isolates which underwent susceptibility testing, all were susceptible to amoxicillin-clavulanate, cefoxitin, metronidazole, piperacillin-tazobactam, ertapenem, and meropenem, 91% were susceptible to clindamycin, 74% were susceptible to moxifloxacin, and 39% were susceptible to penicillin.

Aims: The aim of this study is to investigate the clinical and laboratory characteristics of nonalcoholic fatty liver disease (NAFLD) in a referral center of pediatrics in the northwest of Iran. Methods: In this cross-sectional study all subjects aged between six months to 15 years that were referred to the sonography unit, were investigated for fatty liver from March 2005 to August 2006. Patients with fatty liver change underwent detailed clinical and laboratory evaluation. Results: From 1500 children who were investigated, 34 subjects with sonographic evidence of fatty liver were enrolled in this study (2.3%). The mean age was 6.53 ± 3.07 years. Elevated aspartate aminotransferase and alanine aminotransferase was detected in 38.2% and 47.1% of patients, respectively. The mean level of cholesterol was 461 ± 182.23 mg/dl and 94.1% of patients had hypercholesterolemia. Total cholesterol level and serum aminotransferase levels had a significant positive correlation with severity of fatty liver (p < 0.05). Mean body mass index was significantly higher in patients with severe fatty liver (p < 0.05). Conclusion: The epidemiology of pediatric NAFLD should inform future attempts to develop evaluated screening protocols. Moreover, these data should guide efforts to delineate the pathophysiology of fatty liver in children. PMID:19536316

To determine the relationship between severe tinnitus and inflammation using the neutrophil-to-lymphocyte ratio as a marker of stress. A total of 107 patients who had been suffering with severe tinnitus (tinnitus handicap inventory scale grades of 3-5) for at least 2 weeks were recruited. Patients underwent detailed ENT examinations and audiometric tests to exclude a relevant pathological cause of the tinnitus. Patients with systemic diseases, malignancy or inflammatory diseases that could alter neutrophil-to-lymphocyte ratio were excluded. A total of 107 age- and sex-matched healthy control participants were also recruited. Routine laboratory test results and neutrophil-to-lymphocyte ratio were compared between the patients and controls. Lipid profile, liver function, white blood cell count, haemoglobin level, mean corpuscular volume, and vitamin B12 and folate levels were similar among the patients and controls. However, mean neutrophil-to-lymphocyte ratio was significantly higher among the patients than the controls (p < 0.05). The findings of this novel study suggest that neutrophil-to-lymphocyte ratio should be considered during the evaluation of tinnitus patients as a potential clinical marker of tinnitus. Further studies are required to verify the findings.

The clinical outcomes of lumbar fusion are diminished by the complications associated with the surgical approach. Posterior approaches cause segmental muscular necrosis and anterior approaches risk visceral and vascular injury. This report details a two-year prospective study of a percutaneous method which avoids the major problems associated with existing approaches. Seventeen patients underwent percutaneous, trans-sacral fusion and fixation of L5-S1 with the assistance of computer guidance. Each patient was followed for a minimum of two years post surgery. SF-36 questionnaires and radiographs were obtained preoperatively and at two years post-operatively. Fusion was assessed with post-operative radiographs and/or CT scan. Ninety-three percent of the people fused as judged by plain AP films, Ferguson's view radiographs, and/or CT scans at the two year follow-up. Prospective health and functional SF-36 scores showed significant improvement from the preoperative to the postoperative period. There were no significant complications related to the approach or to the placement of the implants. Percutaneous fusion of the lumbosacral spine appears safe and provides excellent clinical results with a minimal amount of associated tissue trauma.

How happy are patients with their gynaecomastia reduction surgery?

Gynaecomastia reduction surgery is a common male cosmetic procedure. Our clinical experience suggested far lower rates of satisfaction than previously reported. Therefore we evaluated our patient group using a detailed questionnaire designed specifically to assess patient satisfaction with breast attributes and quality-of-life outcome following surgery. The questionnaire was sent to all patients who had surgery for gynaecomastia between January 2000 to January 2006. A total of 74 of the 120 patients contacted returned the questionnaire (62% overall response rate). The patients were divided into 3 groups according to their surgical treatment; liposuction only, excision only and combined excision plus liposuction. The majority of patients underwent surgery for reasons of self-confidence and emotional distress. In all groups surgery resulted in an increase in the mean Likert score (LS). The overall mean LS, combined from all the questions increased from 1.9 ('dissatisfied') to 3.2 ('neither satisfied nor dissatisfied'). Only 62.5% of all patients treated for gynaecomastia were 'satisfied' to 'very satisfied'. This more detailed study has shown that satisfaction rates are not as high as previously published. Patients must be appropriately counselled preoperatively to ensure they have realistic expectations of what can be achieved with surgery.

Purpose To detail the highly variable ocular phenotypes of a French family affected with an autosomal dominantly inherited vitreoretinopathy and to identify the disease gene. Methods Sixteen family members with ten affected individuals underwent detailed ophthalmic evaluation. Genetic linkage analysis and gene screening were undertaken for genes known to be involved in degenerative and exudative vitreoretinopathies. Qualitative reverse transcriptase-PCR analysis of the versiscan (VCAN) transcripts was performed after mutation detection in the VCAN gene. Results The first index patient of this French family was referred to us because of a chronic uveitis since infancy; this uveitis was associated with exudative retinal detachment in the context of a severe uncharacterized familial vitreoretinopathy. Genetic linkage was obtained to the VCAN locus, and we further identified a new pathogenic mutation at the highly conserved splice acceptor site in intron 7 of the VCAN gene (c.4004–2A>T), which produced aberrantly spliced VCAN transcripts. Conclusions Extensive molecular investigation allowed us to classify this familial vitreoretinopathy as Wagner syndrome. This study illustrates the need to confirm clinical diagnosis by molecular genetic testing and adds new ocular phenotypes to the Wagner syndrome, such as vascular and inflammatory features.

The present prospective randomized split-mouth trial reports on the 3-year clinical and radiological follow-up investigation of implants placed 7 months after sinus augmentation with 2 different bone substitute materials. The aim of the study was to complete the histologic observation of cellular reactions by analyses of the implants and the volumetric changes of the augmented bone substitute materials. A sinus augmentation split-mouth trial was performed in 14 patients with the synthetic bone substitute material Nanobone (NB) and the xenogeneic Bio-Oss (BO). Changes in volume and density of the augmented biomaterials were investigated by analysis of computed tomography scans, taken immediately after augmentation and after 7 months. Clinical implant parameters were assessed after 3 years of loading. Both bone substitute materials underwent nonsignificant volume reduction and significant increase in bone density over an integration period of 7 months. No significant differences concerning volume and bone density were observed between the groups. Three years after loading, 51 of 53 implants were in situ with no peri-implant infections, and only a few soft-tissue variations were present. The present prospective randomized study showed that no differences could be observed clinically and radiologically. Accordingly, it seems that both biomaterials, independent of their physicochemical composition, enable clinical success and long-time stability for dental implants. Interestingly, the histological results showed distinct differences in cellular reactions: While the xenogeneic BO induced a mild tissue reaction with only few multinucleated giant cells and comparably low vascularization, the synthetic NB induced a multinucleated giant cell-triggered tissue reaction with an increase of vascularization. Thus, the present study showed that a combination analysis-histological, clinical, and radiological-is necessary for a detailed assessment of a biomaterial's quality for clinical application.

Current AUA guidelines recommend voiding cystourethrogram (VCUG) following endoscopic treatment of vesicoureteral reflux (VUR). We evaluated the clinical and radiographic outcomes of children undergoing Double HIT (hydrodistention implantation technique) for primary VUR to determine success rates and the necessity of postoperative VCUG. Children with a history of febrile urinary tract infection (fUTI) undergoing Double HIT for primary VUR between 2009 and 2012 were identified. Patients were prospectively classified as high or low clinical and radiographic risk. Children were categorized as high clinical risk if they had ≥ 3 fUTIs or documented bladder bowel dysfunction (BBD). High radiographic risk included those <2 years of age or with grade 4-5 VUR. Initially, all children underwent postoperative VCUG ("routine" group), while only those with an indication (high radiographic risk or clinical failure) did so during the latter portion of the study ("indicated" group). Clinical success was defined as no postoperative fUTI and radiographic success as negative postoperative VCUG. Average clinical follow-up was 34.7 ± 17.2 months. Two hundred and twenty-two children (198 girls, 24 boys) underwent Double HIT at a mean age of 4.1 ± 2.7 years. Mean maximum VUR grade was 3 ± 0.8. Sixty-eight children (30.6%) had documented BBD. Fourteen children (6.3%) experienced postoperative fUTI, for a clinical success rate of 93.7%. One hundred and fourteen patients (51.4%) underwent postoperative VCUG; 76 were "routine" and 38 were "indicated" [Figure]. Of children classified as low clinical/radiographic risk, 96.6% did not have a postoperative fUTI, compared to 91.1% for high risk patients (P = 0.771). Odds of clinical success for routine VCUG group were 9.9 times higher than for the indicated VCUG group (95% CI, 2-50). Odds of radiographic success for the routine cohort were 13 times higher than for the indicated group (95% CI, 4.2-40). Nine children (4.1%) underwent additional procedures. We found no difference in clinical success among the different risk groups; the number of children with postoperative fUTI was relatively few so there was not statistical power to discern any differences between patients who experienced clinical success versus clinical failure. However, children with an "indicated" VCUG (i.e. those less than 2 years of age, grade 4-5 VUR or those with a fUTI) were 13 times more likely to experience a radiographic failure. This cohort of 38 patients had a 50% radiographic cure rate and a 78.9% clinical cure rate, compared to the overall long-term clinical success rate of 93.7%. Our data demonstrates that we can predict failures with relatively high sensitivity, and it may therefore be prudent to selectively obtain postoperative VCUG rather than recommend it for all children undergoing dextranomer hyaluronic acid co-polymer (Dx/HA) injection. Our study has several limitations that warrant consideration. Not all children underwent a postoperative VCUG, so the true radiographic success rate is unknown. Incidence of fUTI may also be artificially low, as some radiographic failures proceeded directly to another injection or reimplantation. While we were able to demonstrate that children undergoing an "indicated" VCUG were more likely to experience radiographic failure, a larger patient cohort is necessary to determine whether age or VUR grade is more predictive of failure. Finally all patients underwent endoscopic Dx/HA injection, therefore the incidence "spontaneous resolution" is unknown. Long-term clinical success following Double HIT for the endoscopic correction of primary VUR is high, and the majority of children avoid additional procedures. Unless indicated by high-grade, young age, clinical failure, or family/surgeon preference, consideration should be given to making postoperative VCUG an option rather than a recommendation in children undergoing endoscopic treatment of primary VUR using the Double HIT method.

The aim of this retrospective study was to examine the outcome of patients referred to a dedicated clinic for dental extractions while they were prescribed either oral or intra-venous (IV) bisphosphonates (BPs). The following parameters were assessed: mode of BP administration, indication for BP prescription, incidence of BRONJ, concomitant risk factors for development of bisphosphonate-related osteonecrosis of the jaws (BRONJ) and demographic details. The clinical records of 225 patients who underwent dental extraction while receiving oral or intravenous bisphosphonates were reviewed. Their clinical outcome, specifically the development of BRONJ was determined. Of the 225 patients, 202 were prescribed oral and 23 IV BPs. 34.8% (8/23) of patients prescribed IV BPs developed BRONJ following dental extraction, which was a significantly (p <0.001) higher proportion than that of the oral BP group, which was 2.5% (5/202 patients). 12.3% (8/65) patients taking BPs with steroids were at a significantly increased risk of a BRONJ (p <0.003). 12.3% (7/57) males developed a BRONJ compared with 3.6% (6/168) females where p = 0.015. All of the patients who developed a BRONJ as a result of oral BP prescription had been taking this medication for three years or more. In our patient cohort the risk of developing a BRONJ following dental extractions was greatest in those patients receiving IV BPs and those on oral BPs with concomitant steroid medication.

Purpose: To analyze patterns of failure in patients with head-and-neck cutaneous squamous cell carcinoma (HNCSCC) and clinical/radiologic evidence of perineural invasion (CPNI), in order to define neural clinical target volume (CTV) for treatment planning. Methods and Materials: Patients treated with three-dimensional (3D) conformal or intensity-modulated radiotherapy (IMRT) for HNCSCC with CPNI were included in the study. A retrospective review of the clinical charts, radiotherapy (RT) plans and radiologic studies has been conducted. Results: Eleven consecutive patients with HNCSCCs with CPNI were treated from 2000 through 2007. Most patients underwent multiple surgical procedures and RT courses. The most prevalent failure patternmore » was along cranial nerves (CNs), and multiple CNs were ultimately involved in the majority of cases. In all cases the involved CNs at recurrence were the main nerves innervating the primary tumor sites, as well as their major communicating nerves. We have found several distinct patterns of disease spread along specific CNs depending on the skin regions harboring the primary tumors, including multiple branches of CN V and VII. These patterns and the pertinent anatomy are detailed in the this article. Conclusions: Predictable disease spread patterns along cranial nerves supplying the primary tumor sites were found in this study. Awareness of these patterns, as well as knowledge of the relevant cranial nerve anatomy, should be the basis for CTV definition and delineation for RT treatment planning.« less

To assess the clinical value of 18 F-fluorodeoxyglucose (FDG) positron emission tomography (PET) in a prospective cohort of patients with large vessel vasculitis (LVV) and comparator subjects. Patients with Takayasu arteritis and giant cell arteritis were studied, along with a comparator group consisting of patients with hyperlipidemia, patients with diseases that mimic LVV, and healthy controls. Participants underwent clinical evaluation and FDG-PET imaging, and patients with LVV underwent serial imaging at 6-month intervals. We calculated sensitivity and specificity of FDG-PET interpretation for distinguishing patients with clinically active LVV from comparator subjects and from patients with disease in clinical remission. A qualitative summary score based on global arterial FDG uptake, the PET Vascular Activity Score (PETVAS), was used to study associations between activity on PET scan and clinical characteristics and to predict relapse. A total of 170 FDG-PET scans were performed in 115 participants (56 patients with LVV and 59 comparator subjects). FDG-PET distinguished patients with clinically active LVV from comparator subjects with a sensitivity of 85% (95% confidence interval [95% CI] 69, 94) and a specificity of 83% (95% CI 71, 91). FDG-PET scans were interpreted as active vasculitis in most patients with LVV in clinical remission (41 of 71 [58%]). Clinical disease activity status, disease duration, body mass index, and glucocorticoid use were independently associated with activity on PET scan. Among patients who underwent PET during clinical remission, future clinical relapse was more common in patients with a high PETVAS than in those with a low PETVAS (55% versus 11%; P = 0.03) over a median follow-up period of 15 months. FDG-PET provides information about vascular inflammation that is complementary to, and distinct from, clinical assessment in LVV. FDG-PET scan activity during clinical remission was associated with future clinical relapse. © 2017, American College of Rheumatology.

Purpose The aim of this study was to compare the postoperative clinical and radiological data of patients with vestibular schwannomas who were initially managed by near total resection (NTR) or subtotal resection (STR). The Ki-67 analysis results were compared with tumor regrowth to determine the presence of a correlation between this proliferative index and postoperative tumor regrowth. Study Design Seventeen adult patients (7 male, 10 female) were retrospectively reviewed. Nine (52.9%) and eight (47.1%) patients underwent NTR and STR, respectively. Postoperative clinical and radiological data associated with vestibular schwannoma growth were compared with the Ki-67 immunohistochemical analysis results. Results Evidence of clinically significant regrowth was observed in four (23.5%) patients. Patients who underwent NTR had a lower rate/incidence of tumor regrowth than did patients who underwent STR. Patients with a higher Ki-67 index had the highest tumor regrowth rates. Conclusions Our study indicates that assessment of the Ki-67 index may be useful for determining the probability of regrowth of vestibular schwannomas when only partial removal is accomplished.

To establish a community health care system for screening community-dwelling older people with mild cognitive decline (MCD) and early diagnosis by a medical specialist. Out of all the elderly residents aged 65 years and over living in Yoita town in 2000 (n = 1673), 1544 participated in the interview survey held at community halls or at home (92.3% response). They underwent a Mini-Mental State Examination (MMSE) for assessment of cognitive function and answered questionnaires covering socio-demographic, psychological, physical and medical, and social activity items (2000/11). We defined cognitive decline as an MMSE < or = 1 SD below the age-specific mean (n = 371). Out of a total eligible population of 332, 158 pairs of subjects and their proxies participated in a follow-up survey (2001/11). The subjects themselves underwent MMSE again, and were asked for complaints of memory-related problems. Proxies answered about functional capacity and memory-related problems of subjects, for which we assessed the level of dementia with the Clinical Dementia Rating (CDR). We established criteria for encouragement to undergo detailed examination by a medical specialist as follows. 1) MMSE scores < or = 1 SD below age-specific means at both baseline and follow-up surveys, or 2) CDR > or = 0.5, and 3) not due to mental retardation. Non-participants had significant higher MMSE scores but were younger in the follow-up survey. Out of 96 subjects eligible for the detailed examination, 47 participants showed a tendency for older age with lower MMSE scores or younger age with higher MMSE scores than the average in the follow-up survey. The detailed examinations confirmed dementia of Alzheimer's type in 22 and vascular dementia in 13 on DSM-IV or magnetic resonance imaging. During our screening, 8 community care saloons were opened and the number of facilities for older people with cognitive decline is increasing. To establish a community health care system to screen and cope with community-dwelling older people with MCD in earlier stages, increased awareness of residents with slight MCD is especially important. Our attempt also suggested the importance of educational lectures, methods for testing cognitive function, and dementia care activity.

To determine if the addition of an arterial phase abdominal computed tomography (CT) improves clinical outcomes in patients with blunt splenic injuries. Retrospective review of patients who underwent CT of the abdomen revealing splenic injuries. Clinical management in these patients was determined. Fifty-one of three thousand five hundred twenty-five patients had splenic injuries. Twenty-five patients underwent nonsurgical management, and 3 failed. The theoretical additional arterial phase resulted in a 62% increase in mean effective dose compared to the portal venous phase alone. Routine use of arterial phase CT in blunt trauma patients may not be warranted as there is minimal improvement in outcomes. Copyright © 2015 Elsevier Inc. All rights reserved.

Pituitary gigantism is a rare condition caused by growth hormone secreting hypersecretion, usually by a pituitary tumor. Acromegaly and gigantism cases that have a genetic cause are challenging to treat, due to large tumor size and poor responses to some medical therapies (e.g. AIP mutation affected cases and those with X-linked acrogigantism syndrome). We performed a retrospective study to identify gigantism cases among 160 somatotropinoma patients treated between 1985 and 2015 at the University Hospital of Caracas, Venezuela. We studied clinical details at diagnosis, hormonal responses to therapy and undertook targeted genetic testing. Among the 160 cases, eight patients (six males; 75 %) were diagnosed with pituitary gigantism and underwent genetic analysis that included array comparative genome hybridization for Xq26.3 duplications. All patients had GH secreting pituitary macroadenomas that were difficult to control with conventional treatment options, such as surgery or primary somatostatin receptor ligand (SRL) therapy. Combined therapy (long-acting SRL and pegvisomant) as primary treatment or after pituitary surgery and radiotherapy permitted the normalization of IGF-1 levels and clinical improvement. Novel AIP mutations were the found in three patients. None of the patients had Xq26.3 microduplications. Treatment of pituitary gigantism is frequently challenging; delayed control increases the harmful effects of GH excess, such as, excessive stature and symptom burden, so early diagnosis and effective treatment are particularly important in these cases.

To evaluate the outcomes of changing immunosuppressive therapy for noninfectious uveitis after failure. Retrospective cohort study. Patients with noninfectious uveitis managed at 2 tertiary uveitis clinics in the United Kingdom and Australia. Participants with a history of using immunosuppressive therapy were identified in clinics, and notes were reviewed by doctors trained in uveitis therapy. Each treatment episode/course (starting or changing a therapy) was identified, and demographic details, clinical characteristics, drug used (second-line immunosuppressive agent [ISA] or biologicals), and drug doses were obtained. For each treatment episode, the reasons for changing therapy, corticosteroid-sparing effects, and control of inflammation were determined. A total of 147 patients were identified who underwent 309 different treatment episodes. Fifty-five percent of patients eventually required a change in treatment after their first treatment episode/course. Forty-five episodes involved switching from one ISA to another, with 50% to 100% of these patients achieving "success" (prednisolone ≤10 mg and sustained control) with the new ISA. A combination of ISAs were used in 53 episodes, with "success" being achieved in 50% to 71% of these patients. Biological agents were used in 45 episodes, the most common one being infliximab, which achieved success in 80% of patients. Our data suggest that control of inflammation can be achieved after switching or combining ISAs. Copyright © 2014 American Academy of Ophthalmology. Published by Elsevier Inc. All rights reserved.

Delineation of the Clinical, Molecular and Cellular Aspects of Novel JAM3 Mutations Underlying the Autosomal Recessive Hemorrhagic Destruction of the Brain, Subependymal Calcification and Congenital Cataracts

2014-01-01

We have recently shown that the hemorrhagic destruction of the brain, subependymal calcification and congenital cataracts is caused by biallelic mutations in the gene encoding junctional adhesion molecule 3 (JAM3) protein. Affected members from three new families underwent detailed clinical examination including imaging of the brain. Affected individuals presented with a distinctive phenotype comprising hemorrhagic destruction of the brain, subependymal calcification and congenital cataracts. All patients had a catastrophic clinical course resulting in death in 7 out of 10 affected individuals. Sequencing the coding exons of JAM3 revealed three novel homozygous mutations: c.2T>G (p.M1R), c.346G>A (p.E116K) and c.656G>A (p.C219Y). The p.M1R mutation affects the start codon and therefore is predicted to impair protein synthesis. Cellular studies showed that the p.C219Y mutation resulted in a significant retention of the mutated protein in the endoplasmic reticulum, suggesting a trafficking defect. The p.E116K mutant traffics normally to the plasma membrane as the wild type and may have lost its function due to the lack of interaction with an interacting partner. Our data further support the importance of JAM3 in the development and function of the vascular system and the brain. PMID:23255084

Purpose. To determine the genetic defect and to describe the clinical characteristics in a cohort of mainly nonconsanguineous cone–rod dystrophy (CRD) patients. Methods. One hundred thirty-nine patients with diagnosed CRD were recruited. Ninety of them were screened for known mutations in ABCA4, and those carrying one or two mutations were excluded from further research. Genome-wide homozygosity mapping was performed in the remaining 108. Known genes associated with autosomal recessive retinal dystrophies located within a homozygous region were screened for mutations. Patients in whom a mutation was detected underwent further ophthalmic examination. Results. Homozygous sequence variants were identified in eight CRD families, six of which were nonconsanguineous. The variants were detected in the following six genes: ABCA4, CABP4, CERKL, EYS, KCNV2, and PROM1. Patients carrying mutations in ABCA4, CERKL, and PROM1 had typical CRD symptoms, but a variety of retinal appearances on funduscopy, optical coherence tomography, and autofluorescence imaging. Conclusions. Homozygosity mapping led to the identification of new mutations in consanguineous and nonconsanguineous patients with retinal dystrophy. Detailed clinical characterization revealed a variety of retinal appearances, ranging from nearly normal to extensive retinal remodeling, retinal thinning, and debris accumulation. Although CRD was initially diagnosed in all patients, the molecular findings led to a reappraisal of the diagnosis in patients carrying mutations in EYS, CABP4, and KCNV2. PMID:20554613

This paper, the first in a series of three on 'feline leprosy', provides a detailed description of disease referable to Candidatus 'Mycobacterium tarwinense', the most common cause of feline leprosy in Victoria, Australia. Cases were sourced retrospectively and prospectively for this observational study, describing clinical, geographical and molecular microbiological data for cats definitively diagnosed with Candidatus 'M tarwinense' infection. A total of 145 cases of feline leprosy were scrutinised; 114 'new' cases were sourced from the Victorian Infectious Diseases Reference Laboratory records, veterinary pathology laboratories or veterinarians, and 31 cases were derived from six published studies. Forty-two cats were definitively diagnosed with Candidatus 'M tarwinense' infection. Typically, cats were between 3 and 11 years of age, with no gender predilection, and were generally systemically well. All had outdoor access. Most cats underwent surgical resection of lesions with adjunctive medical therapy, often utilising a combination of oral clarithromycin and rifampicin for at least 3 months. Prognosis for recovery was generally good. Resolution of lesions was not observed in the absence of treatment, but a number of untreated cats continued to enjoy an acceptable quality of life despite persistence of the disease, which extended locally but did not appear to disseminate to internal organs. Preliminary results of draft genome sequencing confirmed that the species is a member of the Mycobacterium simiae complex. Candidatus 'M tarwinense', a fastidious member of the M simiae complex, is capable of causing feline leprosy with a tendency to produce lesions on the head, particularly involving the eyes and periocular skin. The disease has an indolent clinical course and generally responds favourably to therapy despite lesions often containing large numbers of organisms. Detailed genomic analysis may yield clues as to the environmental niche and culture requirement of this elusive organism. Prospective treatment trials and/or drug susceptibility testing in specialised systems would further inform treatment recommendations.

To compare long-term survival and quality of life data in dogs with clinical signs associated with a congenital portosystemic shunt (CPSS) that underwent medical or surgical treatment. Prospective cohort study. 124 client-owned dogs with CPSS. Dogs received medical or surgical treatment without regard to signalment, clinical signs, or clinicopathologic results. Survival data were analyzed with a Cox regression model. Quality of life information, obtained from owner questionnaires, included frequency of CPSS-associated clinical signs (from which a clinical score was derived), whether owners considered their dog normal, and (for surgically treated dogs) any ongoing medical treatment for CPSS. A Mann-Whitney U test was used to compare mean clinical score data between surgically and medically managed dogs during predetermined follow-up intervals. 97 dogs underwent surgical treatment; 27 were managed medically. Median follow-up time for all dogs was 1,936 days. Forty-five dogs (24 medically managed and 21 surgically managed) died or were euthanized during the follow-up period. Survival rate was significantly improved in dogs that underwent surgical treatment (hazard ratio, 8.11; 95% CI, 4.20 to 15.66) than in those treated medically for CPSS. Neither age at diagnosis nor shunt type affected survival rate. Frequency of clinical signs was lower in surgically versus medically managed dogs for all follow-up intervals, with a significant difference between groups at 4 to 7 years after study entry. Surgical treatment of CPSS in dogs resulted in significantly improved survival rate and lower frequency of ongoing clinical signs, compared with medical management. Age at diagnosis did not affect survival rate and should not influence treatment choice.

Primary gastrointestinal non-Hodgkin's lymphoma (PGINHL) is a heterogeneous family of tumors, with treatment modalities including chemotherapy, surgery, and radiotherapy. Because the role of surgery in PGINHL remains disputed, this study aims to assess the impact of operative resection on survival. We used a pathology database to identify all cases of PGINHL diagnosed at a single academic-affiliated medical center from 1988 to 2013. Demographic and clinical data were abstracted from the medical record. We summarized the clinical courses of patients with PGINHL and then performed a survival analysis to compare overall and disease-free survival, stratified by demographic and clinical variables. We identified 33 patients diagnosed with PGINHL during the study period. Of 29 who subsequently received treatment at the institution, 15 initially underwent chemotherapy, 10 underwent surgical resection, and 4 underwent surgery for other reasons such as diagnosis without resection or management of disease complications. Three patients suffered surgical complications and two of these patients died. We found no difference in overall survival between patients receiving surgical resection and patients managed initially with chemotherapy. This case series supports a continued role for surgical resection in the management of patients with PGINHL, though anticipated benefits should be weighed against the risk of complications.

Surgical septal myectomy is performed to relieve left ventricular outflow tract narrowing in severe drug-refractory obstructive hypertrophic cardiomyopathy. The objective of this study was to assess the perioperative and long-term clinical outcome of this procedure performed during infancy. Clinical, transthoracic echocardiographic, electrocardiographic, 24-h Holter, cardiopulmonary exercise test and genetic data were extracted by medical record review. A subset of patients underwent additional prospective detailed clinical evaluation including cardiac magnetic resonance imaging with contrast. Surgery was performed in 23 paediatric patients between 1978 and 2015 at the German Heart Centre Munich. Twelve patients had undergone surgery during infancy (≤ 1 year) (Group A), 11 between 1 and 18 years of age (Group B). The underlying genetic diagnosis was Noonan syndrome spectrum and non-syndromic hypertrophic cardiomyopathy. As compared to Group B, patients in Group A showed more concomitant cardiac procedures and received more homologous transfusions. One perioperative death occurred in Group A, and none in Group B. Two patients in Group A but no patient in Group B required redo septal myectomy. The long-term clinical outcome was similar between the 2 groups. One patient in Group B required cardioverter-defibrillator/pacemaker implantation for higher degree atrioventricular block and none in Group A. There was no evidence of differences in myocardial fibrosis between groups on long-term follow-up magnetic resonance imaging. Surgical septal myectomy can be performed safely during infancy with favourable perioperative and long-term clinical outcome but with a trend towards a higher reoperation rate later in life. © The Author 2017.

To evaluate clinical feasibility of the Pain-QuILT (previously known as the Iconic Pain Assessment Tool) from the perspective of adolescents with chronic pain and members of their interdisciplinary health team. The Pain-QuILT (PQ), a web-based tool that records the visual self-report of sensory pain in the form of time-stamped records, was directly compared with standard interview questions that were transformed to a paper-based tool. Qualitative, semi-structured interviews were used to refine the PQ. Adolescents with chronic pain aged 12 to 18 years used the PQ and comparator tool (randomized order) to self-report pain before a scheduled clinic appointment, and then took part in a semi-structured interview. The health team used these pain reports (PQ and comparator) during patient appointments, and later participated in focus group interviews. Interview audio recordings were transcribed verbatim and underwent a simple line-by-line content analysis to identify key concepts. A total of 17 adolescents and 9 health team members completed the study. All adolescents felt that the PQ was easy to use and understand. The median time required for completion of the PQ and comparator tool was 3.3 and 3.6 minutes, respectively. Overall, 15/17 (88%) of adolescents preferred the PQ to self-report their pain versus the comparator. The health team indicated that the PQ was a clinically useful tool and identified minor barriers to implementation. Consultations with adolescents and their health team indicate that the PQ is a clinically feasible tool for eliciting detailed self-report records of the sensory experience of chronic pain.

To investigate the efficacy and clinical outcome of patients treated with an over-the-scope-clip (OTSC) system for severe gastrointestinal hemorrhage, perforations and fistulas. From 02-2009 to 10-2012, 84 patients were treated with 101 OTSC clips. 41 patients (48.8%) presented with severe upper-gastrointestinal (GI) bleeding, 3 (3.6%) patients with lower-GI bleeding, 7 patients (8.3%) underwent perforation closure, 18 patients (21.4%) had prevention of secondary perforation, 12 patients (14.3%) had control of secondary bleeding after endoscopic mucosal resection or endoscopic submucosal dissection (ESD) and 3 patients (3.6%) had an intervention on a chronic fistula. In 78/84 patients (92.8%), primary treatment with the OTSC was technically successful. Clinical primary success was achieved in 75/84 patients (89.28%). The overall mortality in the study patients was 11/84 (13.1%) and was seen in patients with life-threatening upper GI hemorrhage. There was no mortality in any other treatment group. In detail OTSC application lead to a clinical success in 35/41 (85.36%) patients with upper GI bleeding and in 3/3 patients with lower GI bleeding. Technical success of perforation closure was 100% while clinical success was seen in 4/7 cases (57.14%) due to attendant circumstances unrelated to the OTSC. Technical and clinic success was achieved in 18/18 (100%) patients for the prevention of bleeding or perforation after endoscopic mucosal resection and ESD and in 3/3 cases of fistula closure. Two application-related complications were seen (2%). This largest single center experience published so far confirms the value of the OTSC for GI emergencies and complications. Further clinical experience will help to identify optimal indications for its targeted and prophylactic use.

Recent studies have reported the usefulness of 18 F-FDG PET in aiding with the diagnosis and management of patients with cardiac sarcoidosis (CS). However, image interpretation of 18 F-FDG PET for CS is sometimes challenging. We sought to investigate the inter- and intraobserver agreement and explore factors that led to important discrepancies between readers. Methods: We studied consecutive patients with no significant coronary artery disease who were referred for assessment of CS. Two experienced readers masked to clinical information, imaging reports, independently reviewed 18 F-FDG PET/CT images. 18 F-FDG PET/CT images were interpreted according to a predefined standard operating procedure, with cardiac 18 F-FDG uptake patterns categorized into 5 patterns: none, focal, focal on diffuse, diffuse, and isolated lateral wall or basal uptake. Overall image assessment was classified as either consistent with active CS or not. Results: One hundred scans were included from 71 patients. Of these, 46 underwent 18 F-FDG PET/CT with a no-restriction diet (no-restriction group), and 54 underwent 18 F-FDG PET/CT with a low-carbohydrate, high-fat and protein-permitted diet (low-carb group). There was agreement of the interpretation category in 74 of 100 scans. The κ-value of agreement among all 5 categories was 0.64, indicating moderate agreement. For overall clinical interpretation, there was agreement in 93 of 100 scans (κ = 0.85). When scans were divided into the preparation groups, there was a trend toward higher agreement in the low-carb group versus the no-restriction group (80% vs. 67%, P = 0.08). Regarding the overall clinical interpretation, there was also a trend toward greater agreement in the low-carb group versus the no-restriction group (96% vs. 89%, P = 0.08). Conclusion : The interobserver agreement of cardiac 18 F-FDG uptake image patterns was moderate. However, agreement was better regarding overall interpretation of CS. Detailed prescan dietary preparation seemed to improve interobserver agreement. © 2017 by the Society of Nuclear Medicine and Molecular Imaging.

Photography plays a pivotal role in patient education, photo-documentation, preoperative planning and postsurgical evaluation in plastic surgeries. It has long been serving as a bridge that facilitated communication not only between patients and doctors, but also among plastic surgeons from different countries. Although several basic principles and photographic methods have been proposed, there is no internationally accepted photography that could provide both static and dynamic information in blepharoplasty. In this article, we introduced a novel six-position, frontal view photography for thorough assessment in blepharoplasty. From October 2013 to January 2017, 1068 patients who underwent blepharoplasty were enrolled in our clinical research. All patients received six-position, frontal view photography. Pictures were taken of the patients looking up, looking down, squeezing, smiling, looking ahead and with closed eyes. Conventionally, frontal view photography only contained the last two positions. Then, both novel six-position photographs and conventional two-position photographs were used to appraise postsurgical outcomes. Compared to conventional two-position, frontal view photography, six-position, frontal view photography can provide more detailed, thorough information about the eyes. It is of clinical significance in indicating underlying adhesion of skin/muscle/fat according to individual's features and assessing preoperative and postoperative dynamic changes and aesthetic outcomes. Six-position, frontal view photography is technically uncomplicated while exhibiting static, dynamic and detailed information of the eyes. This innovative method is favorable in eye assessment, especially for revision blepharoplasty. We suggest using six-position, frontal view photography to obtain comprehensive photographs.

To evaluate the use the distance between the adjacent septal nuclei as a surrogate marker of septal area atrophy seen in Alzheimer's disease (AD). Interseptal distance (ISD) was measured, blind to clinical details, in 250 patients who underwent computed tomography (CT) of the brain at University Hospital of Wales. Clinical details including memory problem history were retrieved. An ISD cut-off value that discriminated those with and without memory symptoms was sought. ISD measurements were also made in 20 AD patients. To test both the method and the defined cut-off, measurements were then made in an independent cohort of 21 mild cognitive impairment (MCI) patients and 45 age-matched healthy controls, in a randomised and blinded fashion. ISD measurement was achieved in all patients. In 28 patients with memory symptoms, the mean ISD was 5.9 mm compared with 2.3 mm in those without overt symptoms (p=0.001). The optimum ISD cut-off value was 4 mm (sensitivity 85.7% and specificity 85.8%). All AD patients had an ISD of >4 mm (mean ISD= 6.1 mm). The mean ISD for MCI patients was 3.84 mm compared with 2.18 mm in age-matched healthy controls (p=0.001). Using a 4 mm cut-off correctly categorised 10 mild cognitive impairment patients (47.6%) and 38 healthy controls (84.4%). ISD is a simple and reliable surrogate measurement for septal area atrophy, applicable to CT and magnetic resonance imaging (MRI). It can be used to help select patients for further investigation.

Objective To evaluate if improvement of laparoscopic skills can reduce postoperative peritoneal adhesion formation in a clinical setting. Study Design We retrospectively evaluated 25 women who underwent laparoscopic myomectomy from January 1993 to June 1994 and 22 women who underwent laparoscopic myomectomy from March 2002 to November 2004. Women had one to four subserous/intramural myomas and received surgery without antiadhesive agents or barriers. Women underwent second-look laparoscopy for assessment of peritoneal adhesion formation 12 to 14 weeks after myomectomy. Adhesions were graded according to the Operative Laparoscopy Study Group scoring system. The main variable to be compared between the two cohorts was the proportion that showed no adhesions at second-look laparoscopy. Results Demographic and surgical characteristics were similar between the two cohorts. No complications were observed during surgery. No adverse events were recorded during postoperative course. At second-look laparoscopy, a higher proportion of adhesion-free patients was observed in women who underwent laparoscopic myomectomy from March 2002 to November 2004 (9 out of 22) compared with women who underwent the same surgery from January 1993 to June 1994 (3 out of 25). Conclusion The improvement of surgeons' skills obtained after ten years of surgery can reduce postoperative adhesion formation. PMID:29410967

To report the clinical features, microbial spectrum, and treatment outcomes of endophthalmitis after glaucoma drainage implant (GDI) surgery. Records of patients diagnosed with endophthalmitis after GDI surgery were reviewed. Data on clinical course, microbiological laboratory results, and treatment were analyzed. Of 1,891 eyes that underwent GDI surgery, 14 eyes (0.7%) developed endophthalmitis. The mean time interval between GDI surgery and diagnosis of endophthalmitis was 2.6 ± 3.2 years (median, 1.3 years; range, 11 days-11.4 years). For initial treatment, 13/14 eyes underwent vitreous tap and injection of intravitreal antibiotics and 1/14 eyes underwent primary pars plana vitrectomy. Three additional eyes underwent pars plana vitrectomy because of deteriorating clinical course. Glaucoma drainage implant erosion was present in 9/14 eyes. All 9 eroded GDIs were surgically removed within a mean of 9 ± 5 days (range 2-29 days) after diagnosis of endophthalmitis. Overall, mean logarithm of the minimum angle of resolution best-corrected visual acuity worsened from 0.7 ± 0.7 (Snellen equivalent 20/100) at baseline to 1.6 ± 1.1 (Snellen equivalent 20/800) at final follow-up (P = 0.005). Mean duration between the onset of symptoms and presentation was significantly longer in patients with decreased final best-corrected visual acuity (>2 Snellen lines) compared to patients with stable final best-corrected visual acuity (6.8 vs. 1.0 days; P = 0.005). Glaucoma drainage implant-related endophthalmitis is rare and often associated with GDI erosion. Patients who presented earlier after the onset of symptoms had better final visual outcomes. Prompt evaluation and treatment is required, often with removal of the eroded GDI.

The goal in this review was to summarize the results of clinical neuroimaging studies performed in patients with sports-related concussion (SRC) who were referred to a multidisciplinar ypediatric concussion program. The authors conducted a retrospective review of medical records and neuroimaging findings for all patients referred to a multidisciplinary pediatric concussion program between September 2013 and July 2014. Inclusion criteria were as follows: 1) age ≤ 19 years; and 2) physician-diagnosed SRC. All patients underwent evaluation and follow-up by the same neurosurgeon. The 2 outcomes examined in this review were the frequency of neuroimaging studies performed in this population (including CT and MRI) and the findings of those studies. Clinical indications for neuroimaging and the impact of neuroimaging findings on clinical decision making were summarized where available. This investigation was approved by the local institutional ethics review board. A total of 151 patients (mean age 14 years, 59% female) were included this study. Overall, 36 patients (24%) underwent neuroimaging studies, the results of which were normal in 78% of cases. Sixteen percent of patients underwent CT imaging; results were normal in 79% of cases. Abnormal CT findings included the following: arachnoid cyst (1 patient), skull fracture (2 patients), suspected intracranial hemorrhage (1 patient), and suspected hemorrhage into an arachnoid cyst (1 patient). Eleven percent of patients underwent MRI; results were normal in 75% of cases. Abnormal MRI findings included the following: intraparenchymal hemorrhage and sylvian fissure arachnoid cyst (1 patient); nonhemorrhagic contusion (1 patient); demyelinating disease (1 patient); and posterior fossa arachnoid cyst, cerebellar volume loss, and nonspecific white matter changes (1 patient). Results of clinical neuroimaging studies are normal in the majority of pediatric patients with SRC. However, in selected cases neuroimaging can provide information that impacts decision making about return to play and retirement from the sport.

PURPOSE We aimed to assess the safety and effectiveness of transcatheter arterial embolization (TAE) for mesenteric bleeding following trauma. METHODS From 2001 to 2015, 12 patients were referred to our interventional unit for mesenteric bleeding following trauma, based on clinical decisions and computed tomography (CT) images. After excluding one patient with no bleeding focus and one patient who underwent emergency surgery, a total of 10 patients (male:female ratio, 9:1; mean age, 52.1 years) who underwent super selective TAE of visceral arteries were included in this study. Technical and clinical success, complications, and 30-day mortality rate were analyzed. RESULTS In 10 patients who underwent TAE, the types of trauma were motor vehicle collision (n=6), fall (n=2), assault (n=1), and penetrating injury (n=1), and the bleeding arteries were in the pancreaticoduodenal arterial arcade (n=4), jejunal artery (n=3), colic artery (n=2), and sigmoid artery (n=1). N-butyl-2-cyanoacrylate (NBCA) (n=2), microcoils (n=2), and combinations of NBCA, microcoils, or gelatin sponge particles (n=6) were used as embolic agents. Technical success was achieved in all 10 patients, with immediate cessation of bleeding. Clinical success rate was 90% (9/10), and all patients were discharged with no further treatment required for mesenteric bleeding. However, one patient showed rebleeding 10 days later and underwent repeated TAE with successful result. There were no TAE-related ischemic complications such as bowel infarction. The 30-day mortality rate was 0%. CONCLUSION Our clinical experience suggests that TAE used to control mesenteric bleeding following trauma is safe and effective as a minimally invasive alternative to surgery. PMID:27306658

Female genital malformations represent miscellaneous deviations from normal anatomy. This study aimed to explore the clinical characteristics of patients who underwent surgery for genital tract malformations at Peking Union Medical College Hospital (PUMCH) during a 31-year period. We retrospectively reviewed surgical cases of congenital malformation of the female genital tract at PUMCH for a 31-year period, analyzed the clinical characteristics of 1634 hospitalized patients, and investigated their general condition, diagnosis, and treatment process. The average patient age was 27.6 ± 9.9 years. The average ages of patients who underwent surgery for uterine malformation and vaginal malformation were 31.9 ± 8.8 years and 24.7 ± 9.0 years, respectively; these ages differed significantly (P < 0.01). Among patients with genital tract malformation, the percentages of vaginal malformation, uterine malformation, vulva malformation, cervical malformation, and other malformations were 43.9%, 43.5%, 7.4%, 2.3%, and 2.8%, respectively. Among patients with uterine malformation, 34.5% underwent surgery for the genital tract malformation, whereas in patients with vaginal malformation, the proportion is 70.6%; the difference between the two groups was statistically significant (P < 0.01). The percentage of complications of the urinary system in patients with vaginal malformations was 10.2%, which was statistically significantly higher than that (5.3%) in patients with uterine malformations (P < 0.01). Compared to patients with uterine malformations, patients with vaginal malformations displayed more severe clinical symptoms, a younger surgical age, and a greater need for attention, early diagnosis, and treatment. Patients with genital tract malformations, particularly vaginal malformations, tend to have more complications of the urinary system and other malformations than patients with uterine malformations.

Objective We discuss the strengths of the medical response to the Boston Marathon bombings that led to the excellent outcomes. Potential shortcomings were recognized, and lessons learned will provide a foundation for further improvements applicable to all institutions. Background Multiple casualty incidents from natural or man-made incidents remain a constant global threat. Adequate preparation and the appropriate alignment of resources with immediate needs remain the key to optimal outcomes. Methods A collaborative effort among Boston’s trauma centers (2 level I adult, 3 combined level I adult/pediatric, 1 freestanding level I pediatric) examined the details and outcomes of the initial response. Each center entered its respective data into a central database (REDCap), and the data were analyzed to determine various prehospital and early in-hospital clinical and logistical parameters that collectively define the citywide medical response to the terrorist attack. Results A total of 281 people were injured, and 127 patients received care at the participating trauma centers on that day. There were 3 (1%) immediate fatalities at the scene and no in-hospital mortality. A majority of the patients admitted (66.6%) suffered lower extremity soft tissue and bony injuries, and 31 had evidence for exsanguinating hemorrhage, with field tourniquets in place in 26 patients. Of the 75 patients admitted, 54 underwent urgent surgical intervention and 12 (22%) underwent amputation of a lower extremity. Conclusions Adequate preparation, rapid logistical response, short transport times, immediate access to operating rooms, methodical multidisciplinary care delivery, and good fortune contributed to excellent outcomes.

Aim: To prospectively assess cataract surgery in a major New Zealand public hospital by defining presenting clinical parameters and surgical and clinical outcomes in a cohort of subjects just below threshold for treatment, based upon a points based prioritisation system. Methods: The prospective observational study comprised 488 eyes of 480 subjects undergoing consecutive cataract operations at Auckland Hospital. All subjects underwent extensive ophthalmic examination before and after surgery. Details of the surgical procedure, including any intraoperative difficulties or complications, were documented. Postoperative review was performed at 1 day and 4 weeks after surgery. Demographic data, clinical outcomes, and adverse events were correlated by an independent assessor. Results: The mean age at surgery was 74.9 (SD 9.6) years with a female predominance (62%). Significant systemic disease affected 80% of subjects, with 20% of the overall cohort exhibiting diabetes mellitus. 26% of eyes exhibited coexisting ocular disease and in 7.6% this affected best spectacle corrected visual acuity (BSCVA). A mean spherical equivalent of −0.49 (1.03) D and mean BSCVA of 0.9 (0.6) log MAR units (Snellen equivalent approximately 6/48) was noted preoperatively. Local anaesthesia was employed in 99.8% of subjects (94.9% sub-Tenon's). The majority of procedures (97.3%) were small incision phacoemulsification with foldable lens implant. Complications included: 4.9% posterior capsule tears, 3.8% cystoid macular oedema, and one case (0.2%) of endophthalmitis. Mean BSCVA after surgery was 0.1 (0.2) log MAR units (6/7.5 Snellen equivalent), with a mean spherical equivalent of −0.46 (0.89) D, and was 6/12 or better in 88% of all eyes. A drop in BSCVA, thought to be directly attributable to the surgical intervention, was recorded in a small percentage of eyes (1.5%) after surgery. Conclusion: This study provides a representative assessment of the management of cataract in the New Zealand public hospital system. A predominantly elderly, female population, frequently exhibiting significant systemic illness and coexisting ocular disease, relatively advanced cataracts, and poor BSCVA, presented for cataract surgery. The majority of subjects underwent small incision, phacoemulsification, day case surgery. While almost 90% achieved at least 6/12 BSCVA post-surgery, approximately 5% sustained an adverse intraoperative event and 1.5% of eyes exhibited a reduction in BSCVA postoperatively. PMID:11815345

Malignant melanoma involving the respiratory tract is nearly always metastatic in origin, and primary tumors are very rare. To our knowledge, about 30 cases have been reported in the English literature, one of which involved multiple brain metastases. Here, we report two cases of primary pulmonary malignant melanoma. The first case, which occurred in a 52-year-old Chinese female patient who died 4 months after the initial diagnosis, involved rapid intrapulmonary and intracranial metastases. The second patient, a 65-year-old female, underwent surgical excision, and clinical examination, histopathological characteristics, and immunohistochemical features supported the diagnosis of pulmonary malignant melanoma. No evidence for recurrence and/or metastasis has been found more than one year after the initial surgery. To establish the diagnosis of primary pulmonary malignant melanoma, any extrapulmonary origin must be excluded by detailed examination. Moreover, the tumor should be removed surgically whether it occurs as a single lesion or multiple lesions.

1993-05-01

The development of reliable, easy-to-use magnetic measurement systems with significantly enhanced levels of sensitivity has opened up a number of broad new areas of application for magnetic sensing. Magnetometers based on optical pumping offer sensitivities at the picotesla level, while those that utilize superconducting quantum interference devices can operate at the femtotesla level. These systems are finding applications in areas as diverse as geophysical exploration, communications, and medical diagnostics. This review briefly surveys the capabilities and application areas for a number of magnetic sensing technologies. The emphasis then focuses on the application of the most sensitive of these to the field of medical diagnostics and functional imaging. Protocols for specific applications to noninvasive presurgical planning and to the noninvasive assay of cortical dysfunction in diseases ranging from epilepsy to migraine and schizophrenia will be described in detail. Data will be presented reporting independent validation of these techniques in ten patients who subsequently underwent surgery. Routine and reliable utilization of this ultrasensitive magnetic sensing technology in the clinic is now feasible and practical.

In a study of 40 subjects, who twice underwent extensive dental treatment, the relationships between expectations and experiences of pain and of anxiety were investigated. Inaccurate expectations were adjusted in the same way as observed in the laboratory. Especially anxious subjects expected more pain and anxiety than they experienced, and they appeared to need more experiences before their predictions became accurate. In the course of time, the expectations (and memories) of anxious subjects returned to their original more inaccurate level of prediction. The results suggest that the old schema is ultimately reinstated if disconfirmations are few and far between. Anxious subjects did not experience more pain, but they did experience more anxiety than fearless subjects. Detailed investigation of processes of change after disconfirmation showed that anxiety experienced during treatment is a factor that plays a part in maintaining the problem of inaccurate expectations and fear of treatment. Theoretical and clinical implications of these findings are discussed.

To present the profile of patients undergoing surgical treatment for vertigo at a contemporary institutional vertigo clinic. A retrospective analysis of clinical charts. The charts of 1060 patients, referred to an institutional vertigo clinic from January 2003 to December 2012, were studied. The clinical profile and long-term outcomes of patients who underwent surgery were analysed. Of 1060 patients, 12 (1.13 per cent) were managed surgically. Of these, disease-modifying surgical procedures included perilymphatic fistula repair (n = 7) and microvascular decompression of the vestibular nerve (n = 1). Labyrinth destructive procedures included transmastoid labyrinthectomy (n = 2) and labyrinthectomy with vestibular nerve section (n = 1). One patient with vestibular schwannoma underwent both a disease-modifying and destructive procedure (translabyrinthine excision). All patients achieved excellent vertigo control, classified as per the American Academy of Otolaryngology - Head and Neck Surgery 1995 criteria. With the advent of intratympanic treatments, surgical treatments for vertigo have become further limited. However, surgery with directed intent, in select patients, can give excellent results.

Objectives: To analyze and correlate the clinical and radiographic results from patients with distal radius fractures who underwent surgical treatment with a fixed-angle volar locked plate. Methods: Sixty-four patients with distal radius fractures were evaluated. They all underwent surgical treatment with a volar locked plate for the distal radius, with a minimum of six months of postoperative follow-up. They underwent a physical examination that measured range of motion and grip strength, answered the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire and underwent radiographic examination. Results: In the physical examination on the patients, all the range-of-motion measurements were reduced. Grip strength measured in kgf was on average 85.8% of the strength on the unaffected side. The mean DASH score was 15.99. A significant relationship was found between lower DASH scores and losses of extension and grip strength. On the radiographs, the mean values in relation to the unfractured side were 84.0% for radial inclination, 85.4% for radial length and 86.8% for volar deviation of the radius. Loss of radial length was correlated with losses of extension and grip strength. PMID:27027046

While patients with fibromyalgia report symptoms consistent with cervical myelopathy, a detailed neurological evaluation is not routine. We sought to determine if patients with fibromyalgia manifest objective neurological signs of cervical myelopathy. Two hundred and seventy patients, 18 years and older, who carried the diagnosis of fibromyalgia but who had no previously recognized neurological disease underwent detailed clinical neurological and neuroradiological evaluation for the prevalence of objective evidence of cervical myelopathy and radiological evidence of cerebellar tonsillar herniation (Chiari 1 malformation) or cervical spinal canal stenosis. Patients were primarily women (87%), of mean age 44 years, who had been symptomatic for 8 years (standard deviation, 6.3 years). The predominant complaints were neck/back pain (95%), fatigue (95%), exertional fatigue (96%), cognitive impairment (92%), instability of gait (85%), grip weakness (83%), paresthesiae (80%), dizziness (71%) and numbness (69%). Eighty-eight percent of patients reported worsening symptoms with neck extension. The neurological examination was consistent with cervical myelopathy: upper thoracic spinothalamic sensory level (83%), hyperreflexia (64%), inversion of the radial periosteal reflex (57%), positive Romberg sign (28%), ankle clonus (25%), positive Hoffman sign (26%), impaired tandem walk (23%), dysmetria (15%) and dysdiadochokinesia (13%). MRI and contrast-enhanced CT imaging of the cervical spine revealed stenosis. The mean antero-posterior (AP) spinal canal diameter at C2/3, C3/4, C4/5, C5/6, C6/7 and C7/T1 was 13.5 mm, 11.8 mm, 11.5 mm, 10.4 mm, 11.3 mm and 14.5 mm respectively, (CT images). In 46% of patients, the AP spinal diameter at C5/6 measured 10 mm, or less, with the neck positioned in mild extension, i.e., clinically significant spinal canal stenosis. MRI of the brain revealed tonsillar ectopia >5 mm in 20% of patients (mean=7.1+/-1.8 mm), i.e., Chiari 1 malformation. CONCLUSION. Our findings indicate that some patients who carry the diagnosis of fibromyalgia have both signs and symptoms consistent with cervical myelopathy, most likely resulting from spinal cord compression. We recommend detailed neurological evaluation of patients with fibromyalgia in order to exclude cervical myelopathy, a potentially treatable condition.

Normal pressure hydrocephalus (NPH) remains most often a clinical diagnosis and has been widely considered responsive to the placement of a cerebrospinal fluid (CSF) shunt. The high incidence of patients with Alzheimer's disease (AD) with NPH symptoms leads to poorer outcomes than would be expected in patients with NPH alone. This article reviews a series of patients operated on for presumed NPH in whom preoperative high-volume lumbar puncture (HVLP) and intraoperative cortical brain biopsies were performed. The data derived from these procedures were then used to understand the incidence of AD in patients presenting with NPH symptoms and to analyze the efficacy of HVLP in patients with NPH and patients with concurrent AD (NPH+AD). A review of the outcomes of shunt surgery is provided. The cases of all patients who underwent placement of a CSF shunt for NPH from 1998 to 2013 at the University of Virginia by the senior author were retrospectively reviewed. Patients who underwent HVLP and patients who underwent cortical brain biopsies were stratified based on the biopsy results into an NPH-only group and an NPH+AD group. The HVLP results and outcomes were then compared in these 2 groups. From 1998 to 2013, 142 patients underwent shunt operations because of a preoperative clinical diagnosis of NPH. Of the patients with a shunt who had a diagnosis of NPH, 105 (74%) received HVLPs. Of 142 shunt-treated patients with NPH, 27 (19%) were determined to have concomitant Alzheimer's pathology based on histopathological findings at the time of shunting. Patients who underwent repeat biopsies had an initial positive outcome. After they clinically deteriorated, they underwent repeat biopsies during shunt interrogation, and 13% of the repeat biopsies demonstrated Alzheimer's pathology. Improvements in gait and cognition did not reach significance between the NPH and NPH+AD groups. In total, 105 patients underwent HVLP before shunt placement. In the NPH cohort, 44.6% of patients experienced improvement in symptoms with HVLP and went on to experience resolution or improvement. In the NPH+AD cohort, this proportion was lower (18.2%), and the majority of patients who experienced symptomatic relief with HVLP actually went on to experience either no change or worsening of symptoms (p = 0.0136). A high prevalence of AD histopathological findings (19%) occurred in patients treated with shunts for NPH based on cortical brain biopsies performed during placement of CSF shunts. HVLP results alone were not predictive of clinical outcome. However, cortical brain biopsy results and the presence of Alzheimer's pathology had a strong correlation with success after CSF shunting. Thirteen percent of patients who initially had a normal cortical brain biopsy result had evidence of AD pathology on repeat biopsy, demonstrating the progressive nature of the disease.

To report a case of Alport's syndrome and to present electronmicroscopic examination findings of the anterior lens capsule of this patient. A 21-year-old man was referred for low visual acuity and retinal pigment epithelial changes in the left eye. The patient and his relatives underwent detailed ophthalmological examination, including electrophysiological testing. The patient also underwent electronmicroscopic examination of the anterior lens capsule. His visual acuity was 6/18 OD and 6/15 OS. Anterior lenticonus and subcapsular opacities were observed in the left eye. Cataract extraction by phacoemulsification with intraocular lens implantation was performed for his poor visual performance. During the capsulorhexis, the remarkably thin and fragile anterior capsule was noted and removed. Ultrastructural analysis of the anterior lens capsule showed a thinner central zone compared with the periphery. The course of Alport's syndrome can be ameliorated by early diagnosis. Therefore, the ophthalmological examination of a patient with anterior lenticonus must be combined with a detailed medical evaluation. Ultrastructural analysis of the lens capsule can support the diagnosis of Alport's syndrome.

Purpose A retrospective study to compare the radiologic and clinical outcomes of 2 different anterior approaches, multilevel anterior cervical discectomy with fusion (ACDF) using autologus ticortical bone graft versus anterior cervical corpectomy with fusion (ACCF) using free vascularized fibular graft (FVFG) for the management of cervical spondylotic myelopathy(CSM). Methods A total of 15 patients who underwent ACDF or ACCF using FVFG for multilevel CSM were divided into two groups. Group A (n = 7) underwent ACDF and group B (n = 8) ACCF. Clinical outcomes using Japanese Orthopaedic Association (JOA) score, perioperative parameters including operation time and hospital stay, radiological parameters including fusion rate and cervical lordosis, and complications were compared. Results Both group A and group B demonstrated significant increases in JOA scores. Patients who underwent ACDF experienced significantly shorter operation times and hospital stay. Both groups showed significant increases in postoperative cervical lordosis and achieved the same fusion rate (100 %). No major complications were encountered in both groups. Conclusion Both ACDF and ACCF using FVFG provide satisfactory clinical outcomes and fusion rates for multilevel CSM. However, multilevel ACDF is associated with better radiologic parameters, shorter hospital stay and shorter operative times. PMID:26767152

We aimed to evaluate the safety and clinical effectiveness of fluoroscopically guided large balloon dilatation for treating congenital esophageal stenosis in children. Our study included seven children (mean age 4.0 years) who underwent a total of ten balloon dilatation sessions. The initial balloon diameters were 10-15 mm. The technical success, clinical success (improved food intake and reduced dysphagia within 1 month following the first balloon dilatation), dysphagia recurrence, and complications were retrospectively evaluated. Technical and clinical success rates were 100 %. During the mean 38-month follow-up period after the first balloon dilatation, 3 (43 %) patients underwent only one additional balloon dilatation 4-5 months after the first balloon dilatation for dysphagia recurrence. Two of them showed improvement without further recurrence, while the remaining one underwent partial esophagectomy. Well-contained transmural esophageal rupture (type 2) occurred in two (29 %, 2/7) patients and during two (20 %, 2/10) balloon dilatation sessions. All ruptures were successfully treated conservatively. Our study showed that fluoroscopically guided large balloon dilatation seems to be a simple and effective primary treatment technique for congenital esophageal stenosis in children. Esophageal ruptures were not uncommon although they were not fatal.

The use of genome-wide tests to provide molecular diagnosis for individuals with autism spectrum disorder (ASD) requires more study. To perform chromosomal microarray analysis (CMA) and whole-exome sequencing (WES) in a heterogeneous group of children with ASD to determine the molecular diagnostic yield of these tests in a sample typical of a developmental pediatric clinic. The sample consisted of 258 consecutively ascertained unrelated children with ASD who underwent detailed assessments to define morphology scores based on the presence of major congenital abnormalities and minor physical anomalies. The children were recruited between 2008 and 2013 in Newfoundland and Labrador, Canada. The probands were stratified into 3 groups of increasing morphological severity: essential, equivocal, and complex (scores of 0-3, 4-5, and ≥6). All probands underwent CMA, with WES performed for 95 proband-parent trios. The overall molecular diagnostic yield for CMA and WES in a population-based ASD sample stratified in 3 phenotypic groups. Of 258 probands, 24 (9.3%, 95%CI, 6.1%-13.5%) received a molecular diagnosis from CMA and 8 of 95 (8.4%, 95%CI, 3.7%-15.9%) from WES. The yields were statistically different between the morphological groups. Among the children who underwent both CMA and WES testing, the estimated proportion with an identifiable genetic etiology was 15.8% (95%CI, 9.1%-24.7%; 15/95 children). This included 2 children who received molecular diagnoses from both tests. The combined yield was significantly higher in the complex group when compared with the essential group (pairwise comparison, P = .002). [table: see text]. Among a heterogeneous sample of children with ASD, the molecular diagnostic yields of CMA and WES were comparable, and the combined molecular diagnostic yield was higher in children with more complex morphological phenotypes in comparison with the children in the essential category. If replicated in additional populations, these findings may inform appropriate selection of molecular diagnostic testing for children affected by ASD.

Adhesive small bowel obstruction (ASBO) is a feared complication after abdominal operations in both children and adults. The optimal management of ASBO in the pediatric population is debated. The aim of the present study was to examine the safety and effectiveness of non-operative management in ASBO. A retrospective review of 33 patients who were admitted for ASBO over a 5-year period was carried out. Follow-up data were available for 29 patients. Demographic, clinical, and operative details and outcomes were collected for these patients. Data analysis was done with SPSS version 15.0. P ≤ 0.05 was regarded as significant. Out of 618 abdominal surgeries within the 5-year period, 34 admissions were recorded from 29 patients at the follow-up period of 1-28 months. There were 19 boys (65.5%). The median age of patients was 4.5 years. Typhoid intestinal perforation (n = 7), intussusception (n = 6), intestinal malrotation (n = 5), and appendicitis (n = 4) were the major indications for a prior abdominal surgery leading to ASBO. Twenty-five patients (73.5%) developed SBO due to adhesions within the first year of the primary procedure. Of the 34 patients admitted with ASBO, 18 (53%) underwent operative intervention and 16 (47%) were successfully managed non-operatively. There were no differences in sex (P = 0.24), initial procedure (P = 0.12), age, duration of symptoms, and time to re-admission between the patients who responded to non-operative management and those who underwent operative intervention. However, the length of hospital stay was significantly shorter in the non-operative group (P < 0.0001). Five (14.7%) patients had small bowel resection. A 43-day-old child who initially underwent Ladd's procedure died within 15 h of re-admission while being prepared for surgery, accounting for the only mortality (3.4%). Non-operative management is still a safe and preferred approach in selected patients with ASBO. However, 53% eventually required surgery.

To detail our early experience using concomitant hip arthroscopy and periacetabular osteotomy (PAO) for the treatment of acetabular dysplasia. We prospectively collected and retrospectively reviewed the surgical and outcome data of 17 patients who underwent concomitant hip arthroscopy and PAO between October 2010 and July 2013. Preoperative and postoperative range of motion, outcome and pain scores, and radiographic data were collected. Intraoperative arthroscopic findings and postoperative complications were recorded. The group consisted of 3 male and 14 female patients with a mean follow-up period of 2.4 years. Three patients had undergone previous surgery on the affected hip. Chondrolabral pathology was identified in all 17 patients. Twelve patients underwent labral repair, and five patients underwent partial labral debridement. No patient was converted to total hip arthroplasty or required revision surgery at short-term follow-up. All 4 patient-reported outcome scores showed statistically significant changes from baseline to latest follow-up (P < .001). An excellent outcome was obtained in 82% of patients (13 of 16). The lateral center-edge angle averaged 11° preoperatively and 29° postoperatively. The acetabular inclination averaged 18° preoperatively and 3° postoperatively. The anterior center-edge angle averaged 7° preoperatively and 27° postoperatively. At most recent radiographic follow-up, 1 patient had progression of arthritic changes but remained asymptomatic. No other patient showed any radiographic evidence of progression of arthritis. Complications included 3 superficial wound infections, 1 pulmonary embolism, and 1 temporary sciatic neurapraxia. Our initial experience with concomitant hip arthroscopy and PAO has been favorable. We noted that all our patients have evidence of chondrolabral damage at the time of PAO when the joint is distracted and evaluated. All patients in this series had intra-articular pathology treated arthroscopically and showed satisfactory mean clinical improvement. Hip arthroscopy with PAO did not appear to introduce complications beyond the PAO alone. Level IV, therapeutic case series. Copyright © 2015 Arthroscopy Association of North America.

There is a growing desire for health professions educators to generate high-quality education research; yet, few of them encounter the training to do so. In response, health professions faculties have increasingly been devoting resources to provide members with the skills necessary for education research. The form and impact of these efforts have not been reviewed, though such a synthesis could be useful for practice. The objectives of this systematic review were to (1) identify interventions aimed at building capacity for education research among health professions clinical educators and (2) review the outcomes of these interventions. We developed a systematic review protocol based on our pilot scoping search. This protocol underwent peer review and was prospectively registered with the Best Evidence Medical Education Collaboration. Based on this protocol, we conducted a comprehensive search of health professions' databases and related grey literature. Systematic methods were applied: two independent reviewers completed title screening and full text review for inclusion, data extraction, and methodological quality assessment. Studies were included if they reported outcomes for interventions designed to increase capacity for health professions clinical educators to conduct education research. We conducted a qualitative synthesis of the evidence which included detailed reporting of intervention characteristics and outcomes. Our search returned 14, 149 results, 241 of which were retained after title and abstract screening, and 30 of which met inclusion criteria after full text review. Seven groups of interventions were identified, the most frequent being teaching scholars programs (n = 10), health professions education fellowships (n = 3) or master's programs (n = 4). The most commonly measured outcome was change related to enhanced scholarly outputs (grants, papers, abstracts, and presentations) post-intervention. Unfortunately, most of the included studies lacked detailed description of the intervention and were of low to moderate quality with post-test only design. This review demonstrates that various interventions can have a positive impact on the ability of health professions clinical educators to conduct education research. We note several key elements of the interventions including: (1) protected time, (2) mentorship and/or collaboration, (3) departmental and institutional commitment and leadership, and (4) financial support. Through our analysis we describe the complexities around evaluating clinical educators' health professions research activities and the interventions used to promote education research. While improved study quality would allow more detailed understanding and evaluation of these key features, we are able to provide recommendations for potential strategies for improving participation in and quality of health professions education research based on this analysis.

Early invasive strategies and antithrombotic treatments are key treatments of non-ST-segment-elevation acute coronary syndrome (NSTE-ACS). Few studies have examined the use of these strategies in patients with NSTE-ACS in China. This study aimed to assess the applications of invasive strategies and antithrombotic treatments in patients with NSTE-ACS and compare their outcomes. A nationwide registry study, Improving CCC (Care for Cardiovascular Disease in China) ACS project, was launched in 2014 as a collaborative study of the American Heart Association and Chinese Society of Cardiology (CSC), with 142 participating hospitals reporting details of clinical management and outcomes of patients with NSTE-ACS. The use of invasive strategies and antithrombotic treatments was examined based on updated guidelines. Major adverse cardiovascular events were analyzed. A total of 9953 patients with NSTE-ACS were enrolled. Angiography was performed in 63.1% of these patients, and 58.2% underwent percutaneous coronary intervention (PCI). However, 40.6% of patients did not undergo early risk assessment, and very-high-risk patients had the lowest proportion of PCI (41.7%). PCI was performed within recommended times in 11.1% of very-high-risk patients and 26.3% of high risk patients. Those who underwent PCI within 2 hours had higher mortality in high-risk and very-high-risk patients who received PCI. Early dual antiplatelet treatment was given in 88.3% of patients. There are notable differences between guideline recommendations and the clinical management of patients with NSTE-ACS in China. The reasons for very-high-risk NSTE-ACS patients not undergoing PCI, and the optimal timing of PCI, require further clarification. URL: http://www.clinicaltrials.gov.

Background Chronic thromboembolic pulmonary hypertension results from incomplete resolution of pulmonary emboli. Pulmonary endarterectomy (PEA) is potentially curative, but residual pulmonary hypertension following surgery is common and its impact on long-term outcome is poorly understood. We wanted to identify factors correlated with poor long-term outcome after surgery and specifically define clinically relevant residual pulmonary hypertension post-PEA. Methods and Results Eight hundred eighty consecutive patients (mean age, 57 years) underwent PEA for chronic thromboembolic pulmonary hypertension. Patients routinely underwent detailed reassessment with right heart catheterization and noninvasive testing at 3 to 6 months and annually thereafter with discharge if they were clinically stable at 3 to 5 years and did not require pulmonary vasodilator therapy. Cox regressions were used for survival (time-to-event) analyses. Overall survival was 86%, 84%, 79%, and 72% at 1, 3, 5, and 10 years for the whole cohort and 91% and 90% at 1 and 3 years for the recent half of the cohort. The majority of patient deaths after the perioperative period were not attributable to right ventricular failure (chronic thromboembolic pulmonary hypertension). At reassessment, a mean pulmonary artery pressure of ≥30 mm Hg correlated with the initiation of pulmonary vasodilator therapy post-PEA. A mean pulmonary artery pressure of ≥38 mm Hg and pulmonary vascular resistance ≥425 dynes·s–1·cm–5 at reassessment correlated with worse long-term survival. Conclusions Our data confirm excellent long-term survival and maintenance of good functional status post-PEA. Hemodynamic assessment 3 to 6 months and 12 months post-PEA allows stratification of patients at higher risk of dying of chronic thromboembolic pulmonary hypertension and identifies a level of residual pulmonary hypertension that may guide the long-term management of patients postsurgery.

The aim of this study is to analyze perioperative outcomes of robotic reconstruction of iatrogenic biliary injuries and describe the surgical technique in detail. Iatrogenic bile duct injuries (BDIs) continue to be a major concern in open and laparoscopic cholecystectomy. In the past decade, robotic surgery has been applied to many different procedures showing technical advantages, especially in microsurgical fields. Few cases of robotic BDI reconstructions have been described in the literature so far. This is the first clinical series of consecutive patients undergoing robotic BDI reconstructions. This study is a single-surgeon retrospective review of a prospectively maintained database including 14 patients who underwent robot-assisted biliary reconstruction due to iatrogenic BDIs. In all, 14 patients underwent robot-assisted BDI reconstructions. The mean operative time, blood loss, and length of hospitalization were 280.6 min (SD = 132.0), 135.0 mL (SD = 169.7), and 8.4 days (SD = 6.7), respectively. The conversion rate to open surgery was 0%. Long-term follow-up was available in 85.7% (12 out of 14 patients) with a mean follow-up of 36.1 months (SD = 28.1). The >30-day complication rate was 14.3% (n = 2). These 2 patients presented with recurrent episodes of cholangitis due to hepatico-jejunostomy mild stenosis, which were successfully treated with transhepatic percutaneous biliary drainage and multiple dilatations. Robot-assisted BDI reconstruction is feasible, safe, and may represent an interesting option in expert hands. It maintains all the benefits of minimally invasive surgery and seems to have technical advantages in fine dissection and microsuturing in the liver hilum (magnified microsuturing). In this series, 14 patients with major BDIs were repaired with the robotic approach, with conversion and reoperation rates of 0%. Long-term outcome evaluation requires a longer follow up and larger series, but the initial results are promising.

In patients with acute coronary syndrome (ACS) who underwent coronary arteries revascularization, violations of hemodynamics, metabolism and heart rate variability often develop in the postoperative period, therefore, the goal of the study was to establish the features of disturbances and the effectiveness of correction of left ventricular systolic and diastolic dysfunction and heart rate variability in stages of cardiorehabilitation in patients with acute coronary syndrome who underwent coronary arteries revascularization. The experimental group included 40 patients with ACS in the postoperative period who underwent balloon angioplasty and stenting of the coronary arteries (25 patients with ST-segment elevation ACS and 15 patients without ST-segment elevation ACS). The age of examined patients was 37 to 74 years, an average of 52.6±6.7 years. The control group consisted of 20 patients, comparable in age and clinico-laboratory manifestations of ACS, who underwent drug treatment with direct anticoagulants, double antiplatelet therapy, β-blockers, ACE inhibitors and statins. Clinical efficacy of cardiorespiratory process in patients of both groups was assessed by the dynamics of general clinical symptoms and parameters of natriuretic propeptide, systolic and diastolic function of the left ventricle and heart rate variability. In the initial state, clinical and laboratory-instrumental signs of myocardial ischemia disappear in patients with ACS undergoing surgical revascularization of the coronary arteries, but clinical and subclinical manifestations of heart failure were diagnosed. The use of the accelerated program of cardiac rehabilitation already during the first month of studies leads to a decreasement of the signs of systolic and diastolic dysfunction, the level of NT-proBNP and improve in the variability of the heart rhythm wich significantly improves the life quality of patients with ACS. To monitor the effectiveness and safety of cardiac rehabilitation in patients with ACS who underwent coronary arteries revascularization, in addition to the generally accepted methods (determination of heart rate, blood pressure, a 6-minute test), it is advisable to diagnose the subclinical stage of heart failure by determining the level of NT-proBNP, Doppler echocardiogram, parameters of the left ventricular systolic and diastolic function and heart rate variability.

CASE DESCRIPTION 4 dogs with a slow-growing mass in the cervical region were evaluated. CLINICAL FINDINGS All dogs had no clinical signs at the time of the evaluation. There was no apparent evidence of visceral metastases or other primary tumor based on available CT or MRI data for any dog. TREATMENT AND OUTCOME For each dog, surgery to remove the mass was performed. Histologic examination of the excised tissue revealed a completely excised grade 1 or 2 lymph node hemangiosarcoma. All dogs received adjuvant chemotherapy; 2 dogs underwent curative intent chemotherapy, 1 dog underwent metronomic treatment with cyclophosphamide, and 1 dog underwent metronomic treatment with chlorambucil. The survival time was 259 days in 1 dog; 3 dogs were still alive 615, 399, and 365 days after surgery. CLINICAL RELEVANCE Primary nodal hemangiosarcoma in dogs is a rare and, to the authors' knowledge, previously undescribed disease that appears to develop in the cervical lymph nodes as a slow-growing mass or masses. Surgical excision and adjunct treatment resulted in long survival times for 3 of the 4 dogs of the present report. Given the aggressive biologic behavior of hemangiosarcomas in other body locations, adjunct chemotherapy should be considered for affected dogs, although its role in the cases described in this report was unclear. Additional clinical information is required to further characterize the biologic behavior of this tumor type and determine the expected survival times and associated risk factors in dogs.

The primary aim of this study was to explore the safety and feasibility of laparoscopic-assisted synchronous bowel anastomoses (LSBA) for synchronous colorectal cancer (SCRC). All patients who underwent LSBA for SCRC were retrospectively reviewed and analyzed for clinical and pathological features, technical feasibility and short-term as well as long-term oncological outcomes. Between July 2008 and January 2012, a series of 11 consecutive SCRC patients underwent LSBA. Six patients underwent laparoscopic-assisted right hemicolectomy and anterior resection. Five patients had laparoscopic-assisted right hemicolectomy and sigmoidectomy. There were no intraoperative complications that required open conversions. Mean operation time was 233 (range, 195–285) minutes, and mean estimated blood loss was 224 (range, 100–300) mL. The postoperative course of the patients was uneventful with the mean return to oral intake was 6.9 (range 5–12) days, and mean length of hospital stay was 12.6 (range 9–17) days. All surgical wounds showed good cosmetic outcome, and the mean incision length was 4.1 (range 3.5-5.0) cm. During a median follow-up period of 76 months, no local tumor recurrences were found. LSBA is a potentially feasible and safe procedure for SCRC when performed by an experienced surgeon. Further large clinical controlled trials are warranted to confirm the findings. PMID:27821798

A 38-year-old man was given a diagnosis of as sigmoid colon cancer and underwent sigmoid colectomy. Post-operative pathological staging was stage IIIb. He then underwent adjuvant chemotherapy. One year and 4 months after the surgery, CT scans revealed multiple liver and lung metastases. He was given mFOLFOX6+bevacizumab, which was changed later to FOLFIRI+bevacizumab. After these chemotherapies, he was admitted to the hospital due to sudden abdominal pain and high grade fever. Obstructive jaundice was initially diagnosed, but detailed study of initial CT revealed intragastric wall abscess. After the drainage of the abscess, his conditions improved. We speculated that the abscess formation was caused by mucosal damage due to bevacizumab.

The efficacy of stenting for right-sided malignant colonic obstruction is unknown. This study aimed to evaluate the safety, feasibility, and clinical benefits of self-expandable metallic stent insertion for right-sided malignant colonic obstruction. Clinical data from patients who underwent right hemicolectomy for right colon cancer from January 2006 to July 2014 at three Korea University hospitals were retrospectively reviewed. A total of 39 patients who developed malignant obstruction in the right-sided colon were identified, and their data were analyzed. Stent insertion was attempted in 16 patients, and initial technical success was achieved in 14 patients (87.5 %). No stent-related immediate complications were reported. Complete relief from obstruction was achieved in all 14 patients. Twenty-five patients, including two patients who failed stenting, underwent emergency surgery. In the stent group, 93 % (13/14) of patients underwent elective laparoscopic surgery, and only one surgery was converted to an open procedure. All patients in the emergency group underwent emergency surgery within 24 h of admission. In the emergency group, only 12 % (3/25) of patients underwent laparoscopic surgery, with one surgery converted to an open procedure. All patients in both groups underwent either laparoscopy-assisted or open right/extended right hemicolectomy with primary anastomoses as the first operation. The operative times, retrieved lymph nodes, and pathologic stage did not differ between the two groups. Postoperative hospital stay (9.4 ± 3.4 days in the stent group vs. 12.4 ± 5.9 in the emergency group, p = 0.089) and time to resume oral food intake (3.2 ± 2.1 days in the stent group vs. 5.7 ± 3.4 in the emergency group, p = 0.019) were shorter in the stent group. And there were no significant differences in disease-free survival and overall survival between the two groups. Stent insertion appears to be safe and feasible in patients with right-sided colonic malignant obstruction. It facilitates minimally invasive surgery and may result in better short-term surgical outcomes.

To report clinical characteristics, human leukocyte antigen (HLA) typing and seasonality of birth of a series of 54 Southern Chinese patients suffering from narcolepsy. All subjects underwent detailed medical and psychiatric interviews and a standardised nocturnal polysomnogram followed by a daytime Multiple Sleep Latency Test. Each subject also completed a set of sleep questionnaires. HLA typing was performed in 91% of subjects. A total of 78% and 22% of patients were diagnosed with suffering from cataplectic and non-cataplectic narcolepsy, respectively. The majority (n = 47, 87%) of patients were referred to our sleep clinic for excessive daytime sleepiness (EDS). The cataplectic narcolepsy differed from non-cataplectic narcolepsy by having more rapid eye movement (REM)-related clinical symptoms (more sleep paralysis and sleep-related hallucination) and sleep disturbances (shorter REM latency), as well as tighter association with HLA DQB1*0602. A bi-modal peak pattern was observed at 11 and 39 years old. A similar bi-modal pattern also occurred for EDS and cataplexy. Excess winter births were observed for this series of patients. 81% of patients with cataplectic narcolepsy were DQB1*0602-positive. There were no differences between early- and late-onset cases in the association with positive DQB1*0602 (71.4% vs 60%). Narcolepsy had prominent pernicious effects on various social, academic, family and mental aspects in our patients. In our Southern Chinese narcolepsy series, bi-modal peak pattern of age of onset, excess winter birth and tight association of HLA DQB1*0602 with cataplectic narcolepsy were found.

This analysis was designed to (1) examine the impact of heparin-induced thrombocytopenia (HIT) on contemporary cardiac surgical practice and (2) describe the results of a protocol designed for early identification of the presence of the immune mechanisms involved. Consecutive patients who underwent cardiac surgery were screened postoperatively for thrombocytopenia. Patients with thrombocytopenia were tested for antiplatelet factor 4 (PF4)/heparin antibodies by ELISA and clinical evidence of thrombosis sought. Demographics, co-morbidities, operative details, and outcomes were abstracted from the departmental registry. Of 14,415 consecutive patients undergoing cardiac surgery, 1,849 patients (13%) had thrombocytopenia. Of them, 277 patients (15%) had PF4/heparin antibodies and 76 patients (4%) had both antibodies and clinical thrombosis. Antibodies were more frequent: (1) in women (p = 0.01), (2) in patients with an increased body mass index (p <0.01), and (3) in patients with clinical heart failure before surgery (p <0.01). Thirty-day mortality was greatest among the 76 patients with the triad of thrombocytopenia, antibodies, and clinical thrombosis (30%). Of the 1,849 patients with thrombocytopenia, the presence of PF4/heparin antibodies was an independent predictor of 30-day mortality (odds ratio 2.09, 95% CI 1.46 to 2.49; p <0.001). HIT remains an infrequent but very serious complication of heparin therapy in contemporary cardiac surgical practice. The possibility that the presence of HIT antibodies in patients with thrombocytopenia independently increases operative mortality deserves further study. Copyright © 2016 Elsevier Inc.

Prevalence and Correlates of Rest Tremor in Essential Tremor: Cross-Sectional Survey of 831 Patients Across Four Distinct Cohorts

PubMed Central

Louis, Elan D.; Hernandez, Nora; Michalec, Monika

2015-01-01

Background Essential tremor (ET) is among the most commonly encountered neurological disorders. Its hallmark feature is kinetic tremor. However, other tremors may also occur in ET patients, creating considerable diagnostic confusion among treating physicians. Hence, characterizing the prevalence and clinical accompaniments of these other tremors is of value. Surprisingly, there are few data on the prevalence of rest tremor in ET patients, and even fewer data on the clinical correlates of such tremor. Methods 831 patients in four distinct settings (population, genetics study, study of environmental epidemiology, brain bank) underwent a detailed videotaped neurological examination that was reviewed by a senior movement disorders neurologist. Rest tremor was evaluated in several positions (seated, standing, lying down). Results The prevalence of rest tremor while seated or standing was lowest in the population-based setting (1.9%), highest in the brain bank study (46.4%), and intermediate in the remaining two settings (9.6% and 14.7%, respectively). Rest tremor was restricted to the arms and was not observed in the legs. Rest tremor was associated with older age, longer disease duration (in some studies), greater tremor severity and, to some extent, the presence of cranial tremors. Conclusions Rest tremor can be a common clinical feature of ET. Its prevalence is highly dependent on the setting in which patients are evaluated, ranging from as low as 1% to nearly 50%. Rest tremor seems to emerge as a clinical feature with advancing disease. The anatomical substrates for this type of tremor remain unknown at present. PMID:25786561

Paediatric and adolescent elevated conjunctival lesions in the plical area: lymphoma or reactive lymphoid hyperplasia?

To report clinical, histopathological and molecular features of 'salmon patch'-like conjunctival lesions in paediatric and adolescent patients, and discuss management of these patients and outcome. Patients who presented between 2000 and 2011 with a conjunctival 'salmon-patch'-like lesion in the plical area, were identified by chart review. Clinical parameters, demographic characteristics and details of ophthalmic imaging were collected, and the effect of treatment examined. Eleven patients aged 6-21 years, presented with an elevated pink conjunctival mass in the plical area of one or both eyes. Nine patients underwent an excisional biopsy that histopathologically disclosed extranodal marginal zone B cell lymphoma of mucosa-associated lymphoid tissue (also termed 'MALT lymphoma') in two cases and reactive lymphoid hyperplasia (RLH) in seven cases. Molecular diagnosis showed polyclonal B cells in six patients, monoclonal B cells in two patients, and a questionable status in one patient. Systemic examination disclosed localised ocular adnexal disease in the patients with MALT lymphoma, and none had either local or systemic recurrence during follow-up. Two other patients were treated with antiallergic medication with resolution of the lesion, and were therefore diagnosed clinically with RLH. It is clinically difficult to differentiate between conjunctival RLH and MALT lymphoma in the paediatric and adolescent population. Both lesions are rare in this age group, particularly MALT lymphoma. Molecular analysis of excised lesions does not always correlate with histopathology. A short treatment course with antiallergic drops may sometimes assist diagnosis without compromising the patients due to the indolent nature of lymphoma in that area.

Specialist oncology pharmacists are being trained in Japan to assist cancer treatment teams. These specialized pharmacists address patients' physical and mental problems in pharmacist-managed cancer care clinics, actively participate in formulating treatment policies, and are beneficial in offering qualitative improvements to patient services and team medical care. However, the effect of outpatient treatment by oncology pharmacists on therapeutic outcomes and medical costs is still unknown. A retroactive comparative analysis of the treatment details and clinical course was conducted among three groups of patients: patients who underwent adjuvant chemotherapy managed by a gynecologic oncologist only (S arm), patients managed by a non-oncologist (general practice gynecologist) only (NS arm), and patients managed by both a non-oncologist and a specialist oncology pharmacist (NS+Ph arm). The medical cost per course was significantly lower for patients in the NS+Ph arm than for those in the other two arms. Surprisingly, the outpatient treatment rate in the NS+Ph arm was overwhelmingly high. The involvement of an oncology pharmacist did not make a significant difference in therapeutic outcomes such as recurrence rate and survival. The participation of oncology pharmacists in the management of cancer patients undergoing chemotherapy enables safe outpatient treatment and also reduces medical costs.

This study aimed to describe the technique details of rapid pore cranial drilling with external ventricular drainage and document its clinical outcomes by highlighting the advantages over the traditional and modified cranial drilling technique. Intraventricular hemorrhage is one of the most severe subtypes of hemorrhagic stroke with high mortality. The amount of blood in the ventricles is associated with severity of outcomes, and fast removal of the blood clot is the key to a good prognosis. Between 1977 and 2013, 3773 patients admitted for intraventricular hemorrhage underwent rapid pore cranial drilling drainage. The therapeutic effects and clinical outcomes were retrospectively analyzed. Of these patients, 1049 (27.8%) experienced complete remission, 1788 (47.4%) had improved condition, and 936 (24.8%) died. A total of 3229 (85.6%) patients gained immediate remission. One typical case was illustrated to demonstrate the efficacy of the rapid pore drilling technique. Rapid pore cranial drilling drainage in patients with intraventricular hemorrhage is fast, effective, and provides immediate relief in patients with severe conditions. It could be a better alternative to the conventional drilling approach for treatment of intraventricular hemorrhage. A randomized controlled trial for direct comparison between the rapid pore cranial drilling drainage and conventional drilling technique is in urgent need. PMID:25590642

To perform a genotype-phenotype correlation study in an X-linked congenital idiopathic nystagmus pedigree (pedigree 1) and to assess the allelic variance of the FRMD7 gene in congenital idiopathic nystagmus. Subjects from pedigree 1 underwent detailed clinical examination including nystagmology. Screening of FRMD7 was undertaken in pedigree 1 and in 37 other congenital idiopathic nystagmus probands and controls. Direct sequencing confirmed sequence changes. X-inactivation studies were performed in pedigree 1. The nystagmus phenotype was extremely variable in pedigree 1. We identified 2 FRMD7 mutations. However, 80% of X-linked families and 96% of simplex cases showed no mutations. X-inactivation studies demonstrated no clear causal link between skewing and variable penetrance. We confirm profound phenotypic variation in X-linked congenital idiopathic nystagmus pedigrees. We demonstrate that other congenital nystagmus genes exist besides FRMD7. We show that the role of X inactivation in variable penetrance is unclear in congenital idiopathic nystagmus. Clinical Relevance We demonstrate that phenotypic variation of nystagmus occurs in families with FRMD7 mutations. While FRMD7 mutations may be found in some cases of X-linked congenital idiopathic nystagmus, the diagnostic yield is low. X-inactivation assays are unhelpful as a test for carrier status for this disease.

The purpose of this study was to describe the so-called posterior two-portal approach to the scapula in detail and to investigate the clinical outcome of patients with displaced glenoid and scapular neck fractures who were surgically treated using this approach. From February 1992 to August 2008, 39 patients (30 men and nine women; mean age: 53 years) with scapular fractures underwent surgical fixation at our institution. Thirty-three patients had glenoid fractures and six had unstable scapular neck fractures. All patients were treated via the two-portal approach. The reduction was evaluated radiographically, and the clinical results were analysed using the Constant score. The mean follow-up period was 78 months (range: 6-168). In 24 of the 33 glenoid fractures, the reduction was anatomical. The mean Constant score was 82.3 (range: 35-100) points. In one case, an early postoperative wound infection was cured by local revision, and one patient developed posttraumatic osteoarthritis of the acromioclavicular joint after 2 years. Only one patient developed specific glenohumeral degeneration after non-anatomical reduction. The posterior two-portal approach allows for a good visualisation of the posterior scapular neck and the glenoid area, facilitating the reduction and safe internal fixation of dislocated scapular neck and glenoid fractures.

In many centers, MR imaging of the inner ear and auditory pathway performed on 1.5T or 3T systems is part of the preoperative work-up of cochlear implants. We investigated the applicability of clinical inner ear MR imaging at 7T and compared the visibility of inner ear structures and nerves within the internal auditory canal with images acquired at 3T. Thirteen patients with sensorineural hearing loss eligible for cochlear implantation underwent examinations on 3T and 7T scanners. Two experienced head and neck radiologists evaluated the 52 inner ear datasets. Twenty-four anatomic structures of the inner ear and 1 overall score for image quality were assessed by using a 4-point grading scale for the degree of visibility. The visibility of 11 of the 24 anatomic structures was rated higher on the 7T images. There was no significant difference in the visibility of 13 anatomic structures and the overall quality rating. A higher incidence of artifacts was observed in the 7T images. The gain in SNR at 7T yielded a more detailed visualization of many anatomic structures, especially delicate ones, despite the challenges accompanying MR imaging at a high magnetic field. © 2015 by American Journal of Neuroradiology.

Focal status epilepticus and catastrophic epilepsy are not rare in infants. Epilepsy surgery can be safely done in selected infants to cure epilepsy. We report on an infant who began having drug-resistant status epilepticus at 2 weeks of age and developed epileptic spasms. We discuss in detail how the clinical and electroencephalographic data were used to reach a consensus for epilepsy surgery and why a particular surgical approach was preferred over other alternatives. Presurgical evaluation consisted of 32-channel scalp video EEG using the standard 10-20 system of electrodes, 3-Tesla brain magnetic resonance imaging, and 18 F-fluorodeoxyglucose positron emission tomography. The surgery consisted of resection of the extensive epileptogenic lesion, in addition to disconnection of the left frontal lobe anterior to the motor strip. The infant underwent epilepsy surgery at three months of age. At two-year follow up, she remained seizure free, with no focal motor deficit and the epileptic encephalopathy resolved. The disconnected left frontal lobe shows epileptiform discharges restricted to the disconnected tissue. We highlight the importance of epilepsy surgery in selected infants to achieve seizure freedom and to reverse epileptic encephalopathy. In the process, we demonstrate how epileptic spasms, although clinically and electrographically generalized, resolved after disconnecting the epileptogenic zone.

After-hours radiologic interpretation by nonradiology attendings or resident radiologists introduces the risk of discrepancies. Clinical outcomes following radiologic discrepancies among pediatric emergency department (ED) patients are poorly described. In particular, children with special healthcare needs (CSHCN), have more opportunities for discrepancies and potential consequences than non- CSHCN. Our objective was to determine the rates and types of radiologic discrepancies, and to compare CSHCN to non-CSHCN. From July 2014 to February 2015, all children who underwent a diagnostic imaging study at a free-standing children's ED were included. Data collected included radiologic studies - type and location - and clinical details - chief complaint and CSHCN type. Differences between preliminary reads and final pediatric radiology attending reads were defined as discrepancies, and categorized by clinical significance. Descriptive statistics, z-tests, and chi-square were used. Over 8months, 8310 visits (7462 unique patients) had radiologic studies (2620 CSHCN, 5690 non-CSHCN). A total of 198 (2.4%) radiologic discrepancies [56 (28.3%) CSHCN, 142 (71.7%) non-CSHCN] were found. Chief complaints for CSCHN were more often within the cardiac, pulmonary and neurologic systems (p<0.001 for each), whereas non-CSHCN presented with more trauma (p<0.001). The rates of discrepancies (CSHCN 2.1%, non- CSHCN 2.5%, p=0.3) and severity of clinical consequences (p=0.6) were not significantly different between CSHCN and non-CSHCN. Though the frequency and type of radiologic studies performed between CSHCN and non-CSHCN were different, we found no significant difference in the rate of radiologic discrepancies or the rate of clinically significant radiologic discrepancies.

There are increasing problems with access to both outpatient assessment and joint replacement surgery for patients with hip or knee osteoarthritis. Data were collected on all patients seen at the Joint Clinic over a 2-year period with minimum 12-month follow-up. Patients were assessed by a nurse and a physiotherapist, baseline scores and demographic details collected, and an individualized personal care plan developed. Patients could be referred for a first specialist assessment (FSA) if their severity justified surgical assessment. Three hundred fifty-eight patients were seen at Joint Clinic, of whom 150 (44%) had hip and 189 (56%) had knee OA. The mean age was 67.4 years and there were 152 men (45%) and 187 women (55%). The mean baseline Oxford score was 19.8 (standard deviation 8.2). Fifty-four patients were referred directly to FSA (mean Oxford score 13.0, standard deviation 6.7) and 89 after a subsequent review. The scores of patients referred for FSA were significantly worse than those managed in the Joint Clinic (P < .001). Of the 143 referred for FSA, 115 underwent or were awaiting surgery, 18 were recommended surgery but scored below prioritization threshold, and 10 were not recommended surgery. The Oxford scores of the 194 patients managed non-operatively improved from 22.0 to 25.0 (P = .0013). This study shows that the Joint Clinic was effective as a triage tool with 93% of those referred for FSA being recommended surgery. This has freed up surgeon time to see only those patients most in need of surgical assessment. Copyright © 2017 Elsevier Inc. All rights reserved.

We prospectively assessed the incremental value of a pocket-sized echocardiography (PSE) device during cardiology consultations, in addition to physical examination, ECG reading, and chest x-ray. A total of 443 consecutive patients (53% men), referred for bedside consultations, underwent physical examination, ECG, and CXR, followed by PSE examination. The physician completed a detailed questionnaire (clinical and echocardiographic data, scanning time, abnormal results). Receiver operating characteristic (ROC) curve analysis was generated to test the predictive discrimination value of the different methods. The incremental value of PSE examination compared to clinical visit alone or combined with ECG results was expressed as a global chi-square value. The PSE examination did not influence the definitive diagnosis in only 23.5% of cases, while 25.3% of the diagnoses were confirmed and verified by PSE. The clinical diagnosis was enriched by PSE in 21.9% of cases, and the diagnosis was changed in 26.2%. The area under curve (AUC) of physical examination + ECG results (sensitivity: 80%; specificity: 67%) was significantly higher than physical examination alone (sensitivity: 75%; specificity: 62%) (P < 0.0002), and the AUC of PSE results (sensitivity: 88%; specificity: 86%) was significantly higher than physical examination + ECG results (P < 0.0001). The PSE results, combined with clinical and ECG results, had a significant incremental diagnostic value during cardiology consultation when compared to the clinical visit alone or with ECG results (P < 0.0001). PSE had an incremental diagnostic value during bedside cardiology consultation, increasing the number of appropriate diagnoses and reducing the routine use of echocardiography. © 2015, Wiley Periodicals, Inc.

To show our experience with press-fit cementless stem and metaphyseal fixation with cement in a selected series of patients who underwent revision total knee arthroplasty. Thirty-four patients (35 knees) underwent revision total knee arthroplasty using the press-fit technique. Minimum follow-up was one year (mean 2.2 years) with a maximum length of three years. Of 34 patients, 20 were women and 14 were men. There was one death due to causes not related to arthroplasty and one patient dropout. There were no cases in which further review was necessary. Patients who underwent revision had clinical and functional improvement demonstrated by the results of the KSS, results of the SF-36 quality of life questionnaire, through gains in range of motion and improved limb alignment. There was postoperative clinical and functional improvement in comparison to the preoperative status in revision total knee arthroplasty with press-fit cementless stem.

To determine differences in quality of life (QOL) between patients with head and neck cancer who receive chemoradiation versus chemoradiation and neck dissection. A prospective cohort study was conducted at two tertiary otolaryngology clinics and a Veterans Administration hospital. 103 oropharyngeal patients with Stage IV squamous cell carcinoma treated via chemoradiation +/- neck dissection. self-administered health survey to collect health, demographic, and QOL information pretreatment and 1 year later. QOL via SF-36 and HNQoL. Descriptive statistics were calculated for health/clinical characteristics, demographics, and QOL scores. t tests evaluated changes in QOL over time. Sixty-five patients underwent chemoradiation and 38 patients underwent chemoradiation and neck dissection. Only the pain index of the SF-36 showed a significant difference between groups (P < 0.05) with the neck dissection group reporting greater pain. After post-treatment neck dissection, patients experience statistically significant decrement in bodily pain domain scores, but other QOL scores are similar to those of patients who underwent chemoradiation alone.

This study aimed to determine biopsychosocial differences (anxious-depressive symptomatology and quality of life) among three groups of patients who underwent surgical interventions related to body manipulation, as well as to assess the clinical significance of these results versus reference values. Four groups were compared: women who underwent organ transplant (n = 26), mastectomy for breast cancer (n = 36), breast reconstruction (n = 36), and general population (n = 608). The Hospital Anxiety and Depression Scale and the EORTC QLQ-C30 were used. Women who underwent mastectomy showed the highest anxious-depressive symptomatology and quality-of-life impairment in comparison to the remaining groups, and they also displayed the most clinically significant deterioration in the majority of dimensions (large effect sizes). In contrast, the group with implantation of a healthy organ (transplantation) only showed higher biopsychosocial impairment than the group with reconstruction of an organ (breast reconstruction) in gastrointestinal dysfunctions and in the global self-perception of health.

Nonoperative management for patients with rectal cancer who have achieved a clinical complete response after chemoradiotherapy is becoming increasingly important in recent years. However, the definition of and modality used for patients with clinical complete response differ greatly between institutions, and the role of endoscopic assessment as a nonoperative approach has not been fully investigated. This study aimed to investigate the ability of endoscopic assessments to predict pathological regression of rectal cancer after chemoradiotherapy and the applicability of these assessments for the watchful waiting approach. This was a retrospective comparative study. This study was conducted at a single referral hospital. A total of 198 patients with rectal cancer underwent preoperative endoscopic assessments after chemoradiotherapy. Of them, 186 patients underwent radical surgery with lymph node dissection. The histopathological findings of resected tissues were compared with the preoperative endoscopic findings. Twelve patients refused radical surgery and chose watchful waiting; their outcomes were compared with the outcomes of patients who underwent radical surgery. The endoscopic criteria correlated well with tumor regression grading. The sensitivity and specificity for a pathological complete response were 65.0% to 87.1% and 39.1% to 78.3%. However, endoscopic assessment could not fully discriminate pathological complete responses, and the outcomes of patients who underwent watchful waiting were considerably poorer than the patients who underwent radical surgery. Eventually, 41.7% of the patients who underwent watchful waiting experienced uncontrollable local failure, and many of these occurrences were observed more than 3 years after chemoradiotherapy. The number of the patients treated with the watchful waiting strategy was limited, and the selection was not randomized. Although endoscopic assessment after chemoradiotherapy correlated with pathological response, it is unsuitable for surveillance of patients treated via a nonoperative approach. Incorporation of a "watchful waiting" strategy without establishing proper surveillance protocols and salvage strategies might result in poor local control.

The purpose of this paper is to describe the components of a next-generation electronic nursing records system ensuring full semantic interoperability and integrating evidence into the nursing records system. A next-generation electronic nursing records system based on detailed clinical models and clinical practice guidelines was developed at Seoul National University Bundang Hospital in 2013. This system has two components, a terminology server and a nursing documentation system. The terminology server manages nursing narratives generated from entity-attribute-value triplets of detailed clinical models using a natural language generation system. The nursing documentation system provides nurses with a set of nursing narratives arranged around the recommendations extracted from clinical practice guidelines. An electronic nursing records system based on detailed clinical models and clinical practice guidelines was successfully implemented in a hospital in Korea. The next-generation electronic nursing records system can support nursing practice and nursing documentation, which in turn will improve data quality.

Previous studies have been unable to identify risk factors for prevalent vertebral fractures (VF), which are suitable for use in selection strategies intended to target high-risk sub-groups for diagnostic assessment. However, these studies generally consisted of large epidemiology surveys based on questionnaires and were only able to evaluate a limited number of risk factors. Here, we investigated whether a stronger relationship exists with prevalent VF when conventional risk factors are combined with additional information obtained from detailed one-to-one assessment. Women aged 65-75 registered at four geographically distinct GP practices were invited to participate (n=1,518), of whom 540 attended for assessment as follows: a questionnaire asking about risk factors for osteoporosis such as height loss compared to age 25 and history of non-vertebral fracture (NVF), the get-up-and-go test, Margolis back pain score, measurement of wall-tragus and rib-pelvis distances, and BMD as measured by the distal forearm BMD. A lateral thoraco-lumbar spine X-ray was obtained, which was subsequently scored for the presence of significant vertebral deformities. Of the 509 subjects who underwent spinal radiographs, 37 (7.3%) were found to have one or more VF. Following logistic regression analysis, the four most predictive clinical risk factors for prevalent VF were: height loss (P=0.006), past NVF (P=0.004), history of back pain (P=0.075) and age (P=0.05). BMD was also significantly associated with prevalent VF (P=0.002), but its inclusion did not affect associations with other variables. Factors elicited from detailed one-to-one assessment were not related to the risk of one or more prevalent VFs. The area under ROC curves derived from these regressions, which suggested that models for prevalent VF had modest predictive accuracy, were as follows: 0.68 (BMD), 0.74 (four clinical risk factors above) and 0.78 (clinical risk factors + BMD). Analyses were repeated in relation to the subgroup of 13 patients with two or more VFs, which revealed that in this instance, the Margolis back pain score and rib-pelvis distance were associated with the presence of multiple VFs (P=0.022 and 0.026, respectively). Moreover, the predictive value as reflected by the ROC curve area was improved: 0.80 (BMD), 0.88 (the four most predictive clinical risk factors consisting of the height loss, past NVF, Margolis back pain score and rib-pelvis distance) and 0.91 (clinical risk factors + BMD). Evaluation of additional risk factors from detailed one-to-one assessment does not improve the predictive value of risk factors for one or more prevalent vertebral deformities in postmenopausal women. However, the use of factors such as the Margolis back pain score and rib-pelvis distance may be helpful in identifying postmenopausal women at high risk of multiple prevalent VFs.

We retrospectively reviewed data of patients with incidental prostate cancer (PCa) who underwent radical cystoprostatectomy (RCP) for invasive bladder cancer and we analyzed their features with regard to incidence, pathologic characteristics, clinical significance, and implications for management. Clinical data and pathological features of 64 patients who underwent standard RCP for bladder cancer were included in this study. Besides the urothelial carcinoma of the urinary bladder, the location and tumor volume of the PCa, prostate apex involvement, Gleason score, pathological staging and surgical margins were evaluated. Clinically significant PCa was defined as a tumor with a Gleason 4 or 5 pattern, stage ≥ pT3, lymph node involvement, positive surgical margin or multifocality of three or more lesions. Postoperative follow-up was scheduled every 3 months in the first year, every 6 months in the second and third year, annually thereafter. 11 out of 64 patients (17.2%) who underwent RCP had incidentally diagnosed PCa. 3 cases (27.3%) were diagnosed as significant PCa, while 8 cases (72.7%) were clinically insignificant. The positive surgical margin of PCa was detected in 1 patient with significant disease. The prostate apex involvement was present in 1 patient of the significant PCa group. Median follow-up period was 47.8 ± 29.2 (range 4-79). During the follow-up, biochemical recurrence occurred in 1 patient (9%). Concerning the cancer specific survival there was no statistical significance (P = 0.326) between the clinically significant and clinical insignificant cancer group. In line with published studies, incidental PCa does not impact on the prognosis of bladder cancer of patients undergoing RCP.

Sleep-disordered breathing (SDB) has been recognized as an important risk factor for coronary artery disease (CAD). However, SDB was not fully examined, because sleep studies are limited. Nocturnal pulse oximetry has been suggested to be a useful tool for evaluating SDB. Therefore, the aim of this study was to investigate the influence of SDB assessed by nocturnal pulse oximetry on clinical outcomes in patients who underwent percutaneous coronary intervention (PCI). We conducted a prospective, multicenter, observational cohort study, wherein SDB was assessed by finger pulse oximetry in patients who underwent PCI from January 2014 to December 2016. SDB was defined as 4% oxygen desaturation index of 5 and higher. The primary endpoint was major adverse cardiac or cerebrovascular event (MACCE), defined as a composite of all-cause mortality, acute coronary syndrome, and/or stroke. Of 539 patients, 296 (54.9%) had SDB. MACCE occurred in 32 patients (5.8%) during a median follow-up of 1.9 years. The cumulative incidence of MACCE was significantly higher in patients with SDB (P = 0.0134). In the stepwise multivariable Cox proportional model, the presence of SDB was a significant predictor of MACCE (hazard ratio 2.26; 95% confidence interval 1.05-5.4, P = 0.036). SDB determined by nocturnal pulse oximetry was associated with worse clinical outcomes in patients who underwent PCI. Screening for SDB with nocturnal pulse oximetry was considered to be important for risk stratification in patients with CAD.

Recent reports of infectious outbreaks linked to duodenoscopes have led to proposals for duodenoscope surveillance culturing, which has inherent limitations. We aimed to assess the feasibility of real-time adenosine triphosphate (ATP) testing after manual cleaning and its ability to predict reprocessing adequacy, as determined by terminal duodenoscope cultures. Clinically used duodenoscopes underwent reprocessing per current guidelines. After manual cleaning, ATP samples were obtained from the elevator, within the proximal biopsy port, and by flushing of the biopsy channel. After high-level disinfection (HLD), aerobic cultures of the elevator and biopsy channel were obtained using sterile technique. Duodenoscopes with any ATP sample ≥200 relative light units underwent repeated cycles of cleaning, ATP testing, HLD, and terminal culturing. Twenty clinically used duodenoscopes were included; 18 underwent a second reprocessing cycle, and 6 underwent a third reprocessing cycle because of detection of high ATP. After the initial reprocessing cycle, 12 of 20 (60%) duodenoscopes had positive culture results, most commonly yielding gram-negative bacilli (GNB, n = 11 from 9 duodenoscopes), and catalase-positive gram-positive cocci (CP-GPC, n = 7 from 7 duodenoscopes), suggesting staphylococcal organisms. Ambient environmental controls also showed GNB and CP-GPC growth. The overall sensitivity and specificity of ATP testing compared with terminal cultures were 30% and 53%, respectively. ATP sampling appears to correlate poorly with terminal culture results and cannot be recommended as a surrogate for terminal cultures. The performance and interpretation of cultures remains complicated by the potential recovery of environmental contaminants. Copyright © 2017 American Society for Gastrointestinal Endoscopy.

We determined the risk of arteriovenous fistula after en bloc ligation of the renal hilum. A prospective evaluation of all patients who underwent en bloc ligation of the renal hilum during nephrectomy for malignant disease was performed. Pertinent operative data were recorded and patients were followed for clinical evidence of arteriovenous fistula formation, including hypertension, abdominal bruit and new onset congestive heart failure. Patients with at least 12 months of followup underwent computerized tomographic arteriography to assess arteriovenous fistula formation. A total of 94 patients underwent en bloc renal hilar ligation during open (43) and laparoscopic (51) nephrectomy using a 45 mm titanium endovascular stapler. Of this cohort 11 patients were lost to followup and 3 died of disease. The remaining 80 patients were followed an average of 35.2 months with no clinical evidence of arteriovenous fistula formation. Specifically there was no statistically significant difference in preoperative and postoperative blood pressure (p = 0.18 and 0.62, respectively), no evidence of abdominal bruit on examination and no new onset congestive heart failure. A total of 32 had increased serum creatinine and, therefore, they were excluded from followup computerized tomographic arteriography. Eight patients had a followup of less than 1 year and they were not yet eligible for evaluation. In the 40 patients who underwent computerized tomographic arteriography no fistulas were noted. Based on clinical followup and prospective radiographic evaluation there appears to be a low risk of arteriovenous fistula formation after en bloc ligation of the renal hilum using a titanium endovascular stapler.

Case report of two children sustaining venous air embolism (VAE) during posterior surgery for scoliosis. To report 2 cases where visible bubbling at the operative site was the first clinical indication of VAE-induced cardiovascular collapse and to raise the level of consciousness that VAE in the prone position can occur, often with serious consequences. Twenty-two cases of VAE during surgery for scoliosis in the prone position have been reported. Ten were fatal and ten were in children. Visible bubbling at the operative site was noted in two published cases. Retrospective study of 2 cases of VAE at one institution. Clinical, anesthetic, and radiographic features are presented. Details of previously published cases are reviewed and discussed. Both patients were girls with adolescent scoliosis who underwent prone positioned posterior spinal fusion with instrumentation. Visible bubbling of air at the thoracic aspect of the surgical site was noted near the completion of instrumentation and was the first indication of VAE. In both cases, this was clinically recognized and promptly treated. One patient survived normally and the other died. Visible air bubbling at the operative site may herald the onset of massive VAE during multilevel posterior spinal fusion and instrumentation. A prospective multicenter study using precordial Doppler, central venous catheter, and end-tidal CO2 is recommended to determine the true incidence of VAE in spinal deformity surgery and to evaluate monitoring and treatment methods.

Parkinsonian features have been used as a minor diagnostic criterion for fragile X-associated tremor/ataxia syndrome (FXTAS). However, prior studies have examined parkinsonism (defined as having bradykinesia with at least rest tremor or postural instability) mostly in premutation carriers without a diagnosis of FXTAS. The current study was intended to elaborate this important aspect of the FXTAS spectrum, and to quantify the relationships between parkinsonism, FXTAS clinical staging and genetic/molecular measures. Thirty eight (38) FXTAS patients and 10 age-matched normal controls underwent a detailed neurological examination that included all but one item (i.e. rigidity) of the motor section of the Unified Parkinson's Disease Rating Scale (UPDRS). The FXTAS patient group displayed substantially higher prevalence of parkinsonian features including body bradykinesia (57%) and rest tremor (26%), compared to the control group. Furthermore, parkinsonism was identified in 29% of FXTAS patients. Across all patients, body bradykinesia scores significantly correlated with FXTAS clinical stage, FMR1 mRNA level, and ataxic gait of cerebellar origin, while postural instability was associated with intention tremor. Parkinsonian features in FXTAS appear to be characterized as bradykinesia concurrent with cerebellar gait ataxia, postural instability accompanied by intention tremor, and frequent rest tremor, representing distinctive patterns that highlight the need for further clinical studies including genetic testing for the FMR1 premutation. The association between FMR1 mRNA level and bradykinesia implicates pathophysiological mechanisms which may link FMR1 mRNA toxicity, dopamine deficiency and parkinsonism in FXTAS.

Dedicated breast positron emission tomography (DbPET) provides detailed high-resolution images and can detect intratumoral heterogeneity using 18 F-fluorodeoxyglucose (FDG). We aimed to evaluate the correlation between FDG uptake on DbPET and the clinicopathological features of breast cancer, particularly those with an intratumoral heterogeneous distribution of FDG on DbPET. We evaluated 195 consecutive patients with invasive breast cancer who underwent preoperative whole-body PET (WBPET) and DbPET concurrently between January 2016 and March 2017. The relationships between clinicopathological factors and the maximum standard uptake values (SUVmax) of DbPET and WBPET, including clinical stage, nuclear grade, Ki67 proliferation index, estrogen receptor (ER) and human epidermal growth factor receptor type 2 (HER2) statuses, and the intratumoral heterogeneous distribution of FDG on DbPET, were evaluated. The SUVmax of DbPET was significantly correlated with clinical T stage, N stage, nuclear grade, and Ki67 proliferation index (all p < 0.001) as well as the ER (p = 0.006) and HER2 (p = 0.040) statuses. Intratumoral heterogeneous distribution of FDG on DbPET was significantly related with high nuclear grade (p = 0.016) and high Ki67 proliferation index (p = 0.015) but not with clinical T stage, N stage, and ER and HER2 statuses. The SUVmax of DbPET correlates with clinicopathological factors and also WBPET does. In addition, intratumoral heterogeneity on DbPET provides predictive value for malignancy grade and could inform therapeutic decisions.

Treatment of long, diffuse, in-stent restenotic lesions with beta radiation using strontium 90 and sequential positioning "pullback" technique: procedural details and clinical outcomes.

Long, diffuse, in-stent restenotic lesions have been problematic for many patients, necessitating the need for multiple repeat percutaneous coronary interventions (PCI). The need for repeat PCI has been significantly reduced in patients since the advent of vascular brachytherapy. In-stent restenosis resulting in long lesions (> 30 mm) presents even more of a challenge. The interventional injury length created during PCI is usually greater than 30 mm and the vascular brachytherapy systems available in most hospitals are 30 mm or 40 mm in length. The purpose of this paper is to define "pullback technique" and to report the Montreal Heart Institute (MHI) data to show that the pullback technique using the Novoste system seems to be a safe and effective method for using vascular brachytherapy to treat long, diffuse, in-stent restenotic lesions. We reviewed the database of patients enrolled in the Compassionate Use Registry between August 1999 and July 2000. The data are reported on 23 consecutive patients treated with the pullback technique. The mean lesion length was 49.4 +/- 19.8 mm. Three patients (13%) underwent target vessel revascularization. Angiographic follow-up was obtained in 18 patients (78%). Seven patients (38.8%) showed angiographic restenosis (> 50% luminal re-narrowing). No aneurysms or zones of ectasia were noted. This angiographic and clinical evaluation of the MHI Compassionate Use Registry data show the pullback technique to be safe from both a dosimetric and clinical point of view.

To describe eight patients with active toxoplasmic retinochoroiditis (RC) who had features suggestive of acute choroidal ischemia. A retrospective review of the clinical records of 23 consecutive patients with acute toxoplasmic RC was performed. All patients underwent detailed ophthalmic examination at presentation and throughout follow-up, including dilated biomicroscopic fundus examination, fundus photography, fluorescein angiography, and indocyanine green (ICG) angiography. Of 23 patients, 8 (34.8%) had a large area of retinal whitening surrounding a small focus of RC. Fluorescein as well as ICG angiography showed a well demarcated geographic area of early choroidal hypofluorescence that extended beyond the clinical borders of the white retinal lesion, particularly by ICG angiography. Associated findings for these 8 patients included old retinochoroidal scars (7 [87.5%]), serous retinal detachment (3 [37.5%]), retinal hemorrhages (1 [12.5%]), and multiple satellite dark dots by ICG angiography (6 [75%]). Seven of eight patients were treated using a combination of antitoxoplasmic drugs and corticosteroids. All findings seen at the acute stage resolved in 2 weeks to 6 weeks. A small atrophic retinochoroidal scar replaced the active toxoplasmic lesion and was surrounded with mild or moderate retinal pigment epithelium changes that were associated with decreased final visual acuity in 2 patients (25%). Patients with toxoplasmic RC may develop features suggestive of choroidal ischemia that can result in a transient or permanent decrease in vision. Choroidal ischemia can only be suspected clinically, and fluorescein angiography and ICG angiography are required to establish the definitive diagnosis.

Thyroid-stimulating hormone pituitary adenomas.

Thyroid-stimulating hormone (TSH)-secreting pituitary adenomas are rare, representing < 2% of all pituitary adenomas. The authors conducted a retrospective analysis of patients with TSH-secreting or clinically silent TSH-immunostaining pituitary tumors among all pituitary adenomas followed at their institution between 1987 and 2003. Patient records, including clinical, imaging, and pathological and surgical characteristics were reviewed. Twenty-one patients (6 women and 15 men; mean age 46 years, range 26-73 years) were identified. Of these, 10 patients had a history of clinical hyperthyroidism, of whom 7 had undergone ablative thyroid procedures (thyroid surgery/(131)I ablation) prior to the diagnosis of pituitary adenoma. Ten patients had elevated TSH preoperatively. Seven patients presented with headache, and 8 presented with visual field defects. All patients underwent imaging, of which 19 were available for imaging review. Sixteen patients had macroadenomas. Of the 21 patients, 18 underwent transsphenoidal surgery at the authors' institution, 2 patients underwent transsphenoidal surgery at another facility, and 1 was treated medically. Patients with TSH-secreting tumors were defined as in remission after surgery if they had no residual adenoma on imaging and had biochemical evidence of hypo-or euthyroidism. Patients with TSH-immunostaining tumors were considered in remission if they had no residual tumor. Of these 18 patients, 9 (50%) were in remission following surgery. Seven patients had residual tumor; 2 of these patients underwent further transsphenoidal resection, 1 underwent a craniotomy, and 4 underwent postoperative radiation therapy (2 conventional radiation therapy, 1 Gamma Knife surgery, and 1 had both types of radiation treatment). Two patients had persistently elevated TSH levels despite the lack of evidence of residual tumor. On pathological analysis and immunostaining of the surgical specimen, 17 patients had samples that stained positively for TSH, 8 for alpha-subunit, 10 for growth hormone, 7 for prolactin, 2 for adrenocorticotrophic hormone, and 1 for follicle-stimulating hormone/luteinizing hormone. Eleven patients (61%) ultimately required thyroid hormone replacement therapy, and 5 (24%) required additional pituitary hormone replacement. Of these, 2 patients required treatment for new anterior pituitary dysfunction as a complication of surgery, and 2 patients with preoperative partial anterior pituitary dysfunction developed complete panhypopituitarism. One patient had transient diabetes insipidus. The remainder had no change in pituitary function from their preoperative state. Thyroid-stimulating hormone-secreting pituitary lesions are often delayed in diagnosis, are frequently macroadenomas and plurihormonal in terms of their pathological characteristics, have a heterogeneous clinical picture, and are difficult to treat. An experienced team approach will optimize results in the management of these uncommon lesions.

Clinical indications for vocal fold injection augmentation (VFI) are expanding. Prior studies demonstrate the benefit of trial VFI for select causes of glottic insufficiency. No studies have examined trial VFI for glottic insufficiency resulting from true vocal fold (TVF) scar. Retrospective chart review of patients who underwent trial VFI for a dominant pathology of TVF scar causing dysphonia. Patients who subsequently underwent durable augmentation were identified. The primary study outcome was the difference in Voice Handicap Index-10 (VHI-10) score from pretrial VFI to post-durable augmentation. Twenty-eight patients underwent trial VFI for TVF scar, 22 of whom reported a positive response. Fifteen of 22 subjects who underwent durable augmentation had viable data for analysis. Mean VHI-10 improved from 26.9 to 18.6 ( P < .05), for a delta VHI-10 of 8.3, or 30.9% improvement. Twelve of the 15 (80%) showed a clinically significant improvement (delta VHI-10 >5). A trial VFI is a potentially useful, low-risk procedure that appears to help the patient and clinician identify when global augmentation might improve the voice when vocal fold scar is present. Patients who reported successful trial VFI often demonstrated significant improvement in their VHI-10 after subsequent durable augmentation.

Separation, Aspiration, and Fat Equalization: SAFE Liposuction Concepts for Comprehensive Body Contouring.

PubMed

Wall, Simeon H; Lee, Michael R

2016-12-01

Separation, aspiration, and fatty equilibration (SAFE) liposuction uses a process approach to body contouring and minimizes injury to surrounding structures. The multistep process allows for (1) fat separation, (2) lipoaspiration, and (3) fat equalization. The purpose of this study was to review both outcomes and complications of primary SAFE liposuction. Retrospective chart review was completed of patients undergoing SAFE liposuction from January of 2006 to January of 2011. Patient selection was limited to those undergoing liposuction alone with no adjuvant excisional procedures. Data were collected regarding demographics, body mass index, operative details, and outcomes. Seven hundred thirty-four patients were identified as having undergone SAFE liposuction. One hundred twenty-nine patients were found to have been treated with liposuction alone. Patient age ranged from 18 to 42 years and body mass index ranged from 18 to 42 kg/m (mean, 26.3 kg/m). Seven patients (5.4 percent) underwent treatment of the face and neck, six patients (4.7 percent) underwent treatment of upper extremities, 13 patients (10.1 percent) underwent treatment of the chest, 20 patients (15.5 percent) underwent treatment of lower extremities, 32 patients (24.8 percent) underwent treatment of the circumferential trunk, and 51 patients (39.5 percent) underwent treatment of circumferential trunk and additional area(s). No major complications occurred. Five of the 129 patients (3.87 percent) developed the minor complication of seroma formation. SAFE liposuction is a multistep process approach to body contouring consisting of (1) fat separation, (2) lipoaspiration, and (3) fat equalization. The results of this study show such technique to be safe and effective. Therapeutic, IV.

Neuralgic amyotrophy (NA) often imposes diagnostic problems. Recently, MRI and high-resolution ultrasound (HRUS) have proven useful in diagnosing peripheral nerve disorders. We performed a chart and imaging review of patients who were examined using neuroimaging and who were referred because of clinically diagnosed NA between March 1, 2014 and May 1, 2015. Six patients were included. All underwent HRUS, and 5 underwent MRI. Time from onset to evaluation ranged from 2 weeks to 6 months. HRUS showed segmental swelling of all clinically affected nerves/trunks. Atrophy of muscles was detected in those assessed >1 month after onset. MRI showed T2-weighted hyperintensity in all clinically affected nerves, except for the long thoracic nerve, and denervation edema of muscles. HRUS and MRI are valuable diagnostic tools in NA. This could change the diagnostic approach from one now focused on excluding other disorders to confirming NA through imaging markers. Muscle Nerve 54: 1079-1085, 2016. © 2016 Wiley Periodicals, Inc.

AIM: To evaluate the clinical results of angiography and embolization for massive gastrointestinal hemorrhage after abdominal surgery. METHODS: This retrospective study included 26 patients with postoperative hemorrhage after abdominal surgery. All patients underwent emergency transarterial angiography, and 21 patients underwent emergency embolization. We retrospectively analyzed the angiographic features and the clinical outcomes of transcatheter arterial embolization. RESULTS: Angiography showed that a discrete bleeding focus was detected in 21 (81%) of 26 patients. Positive angiographic findings included extravasations of contrast medium (n = 9), pseudoaneurysms (n = 9), and fusiform aneurysms (n = 3). Transarterial embolization was technically successful in 21 (95%) of 22 patients. Clinical success was achieved in 18 (82%) of 22 patients. No postembolization complications were observed. Three patients died of rebleeding. CONCLUSION: The positive rate of angiographic findings in 26 patients with postoperative gastrointestinal hemorrhage was 81%. Transcatheter arterial embolization seems to be an effective and safe method in the management of postoperative gastrointestinal hemorrhage. PMID:24187463

Episodic memories undergo qualitative changes with time, but little is known about how different aspects of memory are affected. Different types of information in a memory, such as perceptual detail, and central themes, may be lost at different rates. In patients with medial temporal lobe damage, memory for perceptual details is severely impaired, while memory for central details is relatively spared. Given the sensitivity of memory to loss of details, the present study sought to investigate factors that mediate the forgetting of different types of information from naturalistic episodic memories in young healthy adults. The study investigated (1) time-dependent loss of “central” and “peripheral” details from episodic memories, (2) the effectiveness of cuing with reminders to reinstate memory details, and (3) the role of retrieval in preventing forgetting. Over the course of 7 d, memory for naturalistic events (film clips) underwent a time-dependent loss of peripheral details, while memory for central details (the core or gist of events) showed significantly less loss. Giving brief reminders of the clips just before retrieval reinstated memory for peripheral details, suggesting that loss of details is not always permanent, and may reflect both a storage and retrieval deficit. Furthermore, retrieving a memory shortly after it was encoded prevented loss of both central and peripheral details, thereby promoting retention over time. We consider the implications of these results for behavioral and neurobiological models of retention and forgetting. PMID:26773100

2003-03-01

Detailed clinical models are necessary to exchange medical data between heterogeneous computer systems and to maintain consistency in a longitudinal electronic medical record system. At Intermountain Health Care (IHC), we have a history of designing detailed clinical models. The purpose of this paper is to share our experience and the lessons we have learned over the last 5 years. IHC's newest model is implemented using eXtensible Markup Language (XML) Schema as the formalism, and conforms to the Health Level Seven (HL7) version 3 data types. The centerpiece of the new strategy is the Clinical Event Model, which is a flexible name-value pair data structure that is tightly linked to a coded terminology. We describe IHC's third-generation strategy for representing and implementing detailed clinical models, and discuss the reasons for this design.

The Ross procedure is used in the treatment of selected patients with aortic valve disease. Pulmonary graft stenosis can appear in the long-term follow-up after the Ross intervention, but the factors involved and its clinical implications are not fully known. To describe the incidence, clinical impact and predictors of homograft stenosis and reintervention after the Ross procedure in a prospective series in a tertiary referral hospital. From 1997 to 2009, 107 patients underwent the Ross procedure (mean age: 30±11 years; 69% men; 21 aged<18 years), and were followed for echocardiographic homograft stenosis (peak gradient>36mmHg) and surgical or percutaneous homograft reintervention. After 15 years of follow-up (median: 11 years), echocardiographic and clinical data were available in 91 (85%) and 104 (98%) patients, respectively: 26/91 (29%) patients developed homograft stenosis; 10/104 (10%) patients underwent 13 homograft reintervention procedures (three patients underwent surgical replacement, three received a percutaneous pulmonary valve and one needed stent implantation). The other three patients underwent two consecutive procedures in follow-up; one died because of a procedure-related myocardial infarction. Rates of survival free from homograft stenosis and reintervention at 1, 5 and 10 years were 96%, 82% and 75% and 99%, 94% and 91%, respectively. Paediatric patients had worse survival free from homograft stenosis (hazard ratio [HR] 3.50, 95% confidence interval [CI]: 1.56-7.90; P=0.002), although there were no significant differences regarding reintervention (HR: 2.01, 95% CI: 0.52-7.78; P=0.31). Younger age of homograft donor was also a stenosis predictor (HR: 0.97, 95% CI: 0.94-0.99; P=0.046). The probabilities of homograft stenosis and reintervention 10 years after the Ross procedure were 29% and 10%, respectively; only one patient had a reintervention-related death. Younger donor and recipient age were associated with a higher rate of stenosis. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

To investigate whether serum levels of estradiol affect reproductive outcomes of normoresponder women undergoing fresh embryo transfer (ET) versus frozen-thawed ET (FET). Two hundred fifty-five normoresponder women underwent fresh ET in their first or second in vitro fertilization cycle. Ninety-two women with negative pregnacy test results underwent FET. Clinical and ongoing pregnancy rates, implantation, and live birth rates of women undergoing fresh ET versus FET were compared. One hundred forty-seven (57.65%) out of the 255 normoresponder women receiving FET had positive beta-human chorionic gonadotrophin (hCG) results. The remaining 108 women had negative beta-hCG results. The clinical pregnancy rates of the fresh ET group were found as 55.69% (n=142). Ninety-two of the 108 women with failed pregnancies underwent FET; 72.83% had positive beta-hCG results (n=67), and 70.65% had clinical pregnancy (n=65). Both biochemical and clinical pregnancy rates of women undergoing FET increased significantly (p<0.012 and p<0.013, respectively). Ongoing pregnancy (60.87% vs. 52.94%) and live birth rates (59.87% vs. 48.63%) were similar in both fresh and FET groups. Serum E2 levels of women who failed to conceive were significantly higher than those women did conceive. Serum progesterone levels of women who conceived versus those that did not were similar. The detrimental effect of high serum estradiol levels on endometrial receptivity could be prevented by FET.

Although international commerce in kidney transplantation is a reality, little is known about U.S. residents who travel abroad for kidney transplantation. We retrospectively reviewed the clinical outcomes of patients who were evaluated at the University of Minnesota Medical Center or Hennepin County Medical Center, but then surreptitiously underwent kidney transplantation overseas. We identified 10 patients who underwent kidney transplantation outside the United States between September 16, 2002 and June 30, 2006 and then returned for care in our programs. Eight were transplanted in Pakistan (all Somali), one was transplanted in China (Chinese), and one was transplanted in Iran (Iranian). All but one had a living donor. Mean age was 36.8+/-12.5 years with median follow-up of 2.0 years (range 0.4-3.7). Three patients communicated their intent to travel abroad before transplantation. Induction immunosuppressive therapy (if any) was available in 3/10, and initial maintenance immunosuppression was known in 5/10. Complications were primarily infectious, with six potentially life-threatening infections in four patients. At last follow-up, mean serum creatinine was 1.13+/-0.34 mg/dL, acute rejection occurred in 2/10, 1/10 grafts failed due to acute rejection, and 9/10 patients were alive. Kidney function and graft survival were generally good after surreptitious overseas kidney transplantation. Major problems included incomplete perioperative information communicated to the posttransplant care facility and a high incidence of posttransplant infections. Longer follow-up and detailed cost analysis are needed to better understand the implications of the growing phenomenon of transplant tourism.

Major bile duct injuries occur infrequently after laparoscopic cholecystectomy, but may result in life-threatening complications. Few data exist on the financial implications of duct repair. This study calculated the costs of operative repair in a cohort of patients who underwent reconstruction of the bile duct after major ductal injury. To calculate the total in-hospital cost of surgical repair of patients referred with major bile duct injuries. A prospective database was reviewed to identify all patients referred to the University of Cape Town Private Academic Hospital, South Africa, between 2002 and 2013 for assessment and repair of major laparoscopic bile duct injuries. The detailed clinical records and billing information were evaluated to determine all costs from admission to discharge. Total costs for each patient were adjusted for inflation between the year of repair and 2013. Results. Forty-four patients (33 women, 11 men; median age 48 years, range 30 - 78) underwent reconstruction of a major bile duct injury. First-time repairs were performed at a median of 24.5 days (range 1 - 3,662) after initial surgery. Median hospital stay was 15 days (range 6 - 86). Mean cost of repair was ZAR215,711 (range ZAR68,764 - 980,830). Major contributors to cost were theatre expenses (22%), admission to intensive care (21%), radiology (17%) and specialist fees (12%). Admission to a general ward (10%), consumables (7%), pharmacy (5%), endoscopy (3%) and laboratory costs (3%) made up the balance. The cost of repair of a major laparoscopic bile duct injury is substantial owing to prolonged hospitalisation, complex surgicalintervention and intensive imaging requirements.

The aim of this study was to compare De Vega semicircular annuloplasty and a new biodegradable ring annuloplasty technique in patients requiring surgical intervention for tricuspid valve disease with concomitant disease of the mitral valve. Between January 2004 and May 2008, 129 consecutive patients underwent annuloplasty procedures to correct tricuspid valve regurgitation during a concomitant mitral valve operation requiring replacement. Additionally, 24 patients underwent aortic valve replacement (AVR), 11 underwent coronary artery bypass grafting (CABG), 5 underwent AVR plus CABG, 3 underwent mitral valve replacement plus atrial septal defect (ASD) closure, and 2 underwent ASD closure. The patients in this study were assigned to 2 groups: Kalangos ring annuloplasty was performed in 67 patients (group 1), and De Vega semicircular annuloplasty was performed in the remaining 62 patients (group 2). Both tricuspid valve repair techniques produced a low rate of complications; however, the number of patients who developed residual tricuspid regurgitation was significantly lower in group 1. The biodegradable ring annuloplasty technique may be used easily and safely in moderate and severe cases of tricuspid regurgitation; however, larger clinical series are necessary to confirm our promising results.

Objectives The purpose of this study was to test the feasibility of an electronic nursing record system for perinatal care that is based on detailed clinical models and clinical practice guidelines in perinatal care. Methods This study was carried out in five phases: 1) generating nursing statements using detailed clinical models; 2) identifying the relevant evidence; 3) linking nursing statements with the evidence; 4) developing a prototype electronic nursing record system based on detailed clinical models and clinical practice guidelines; and 5) evaluating the prototype system. Results We first generated 799 nursing statements describing nursing assessments, diagnoses, interventions, and outcomes using entities, attributes, and value sets of detailed clinical models for perinatal care which we developed in a previous study. We then extracted 506 recommendations from nine clinical practice guidelines and created sets of nursing statements to be used for nursing documentation by grouping nursing statements according to these recommendations. Finally, we developed and evaluated a prototype electronic nursing record system that can provide nurses with recommendations for nursing practice and sets of nursing statements based on the recommendations for guiding nursing documentation. Conclusions The prototype system was found to be sufficiently complete, relevant, useful, and applicable in terms of content, and easy to use and useful in terms of system user interface. This study has revealed the feasibility of developing such an ENR system. PMID:22844649

Purpose To determine if a reduced-dose computed tomography (CT) protocol could effectively help to identify patients in the emergency department (ED) with moderate to high likelihood of calculi who would require urologic intervention within 90 days. Materials and Methods The study was approved by the institutional review board and written informed consent with HIPAA authorization was obtained. This was a prospective, single-center study of patients in the ED with moderate to high likelihood of ureteral stone undergoing CT imaging. Objective likelihood of ureteral stone was determined by using the previously derived and validated STONE clinical prediction rule, which includes five elements: sex, timing, origin, nausea, and erythrocytes. All patients with high STONE score (STONE score, 10–13) underwent reduced-dose CT, while those with moderate likelihood of ureteral stone (moderate STONE score, 6–9) underwent reduced-dose CT or standard CT based on clinician discretion. Patients were followed to 90 days after initial imaging for clinical course and for the primary outcome of any intervention. Statistics are primarily descriptive and are reported as percentages, sensitivities, and specificities with 95% confidence intervals. Results There were 264 participants enrolled and 165 reduced-dose CTs performed; of these participants, 108 underwent reduced-dose CT alone with complete follow-up. Overall, 46 of 264 (17.4%) of patients underwent urologic intervention, and 25 of 108 (23.1%) patients who underwent reduced-dose CT underwent a urologic intervention; all were correctly diagnosed on the clinical report of the reduced-dose CT (sensitivity, 100%; 95% confidence interval: 86.7%, 100%). The average dose-length product for all standard-dose CTs was 857 mGy · cm ± 395 compared with 101 mGy · cm ± 39 for all reduced-dose CTs (average dose reduction, 88.2%). There were five interventions for nonurologic causes, three of which were urgent and none of which were missed when reduced-dose CT was performed. Conclusion A CT protocol with over 85% dose reduction can be used in patients with moderate to high likelihood of ureteral stone to safely and effectively identify patients in the ED who will require urologic intervention.

The implantation of inflatable penile prosthesis (IPP) with simultaneous manual penile remodeling allows for men to undergo a single procedure aimed at correcting both the penile deformity/curvature and erectile dysfunction (ED). To evaluate the clinical outcomes and patient satisfaction in men with Peyronie's disease (PD) and ED who underwent AMS 700™ CX and the newer Coloplast™ Titan inflatable penile prosthesis (IPP) implant. Patient demographics, type of IPP, clinical outcomes, post-implant sexual characteristics, and overall patient satisfaction. A single-center retrospective review of clinical database and prospective telephone survey were conducted in all men with PD who underwent IPP between January 2006 and November 2010. A total of 138 patients with an average age of 57.7 (32 to 80) underwent AMS 700 CX (88 patients) and Coloplast Titans (50 patients) IPP implantation during the 5-year period. The majority of patients (91%) had only one IPP implantation. The IPP clinical outcomes include eight (6%) revision surgery for device malfunction and three (2%) device explantation for prosthesis infection. While there was no statistically significance in device survival between the two devices, the trend favored AMS 700 CX over Titan (5-year Kaplan-Meier estimates of mechanical survival were 91% vs. 87%, P>0.05) and both IPPs provided similar penile straightening without the need for revision surgery. Most men (79%) reported great satisfaction following CX or Titan implants with greater than two thirds of men reported greater self-confidence and 82% of patients would undergo the same operation again. AMS 700™ CX and Coloplast™ Titan IPP implantation and penile remodeling appeared to provide permanent penile straightening and high patient satisfaction without an increase risk of revision surgery. © 2012 International Society for Sexual Medicine.

Aims and Objectives: To assess the diagnostic utility of contrast-enhanced 18F-fluorodeoxyglucose positron emission tomography-computed tomography (FDG PET-ceCT) in localization of tumors in patients with clinical diagnosis of tumor-induced osteomalacia (TIO), in correlation with histopathological results. Materials and Methods: Eight patients (five male and three female) aged 24–60 (mean 42) years with a clinical diagnosis of TIO were included in this prospective study. They underwent whole body (head to toe) FDG PET-ceCT following a standard protocol on Philips GEMINI TF PET-CT scanner. The FDG PET-ceCT results were correlated with postoperative histology findings and clinical follow-up. Results: All the patients had an abnormal PET-ceCT study. The sensitivity of PET-ceCT was 87.5%, and positive predictive value was 100%. The tumor was located in the craniofacial region in 6/8 patients and in bone in 2/8 patients. Hemangiopericytoma was the most common reported histology. All patients underwent surgery, following which they demonstrated clinical improvement. However, one patient with atypical findings on histology did not show any clinical improvement, hence, underwent 68Gallium-DOTANOC PET-ceCT scan for relocalization of the site of the tumor. Conclusion: The tumors causing TIO are small in size and usually located in obscure sites in the body. Hence, head to toe protocol should be followed for FDG PET-ceCT scans with the inclusion of upper limbs. Once the tumor is localized, regional magnetic resonance imaging can be performed for better characterization of soft tissue lesion. Imaging with FDG PET-ceCT plays an important role in detecting the site of the tumor and thereby facilitating timely management. PMID:26917888

PurposeThe Habib™ VesOpen Catheter is a new endovascular radiofrequency ablation (RFA) device used to treat malignant portal obstruction. The purpose of this study was to evaluate the clinical feasibility and safety of RFA with this device.MethodsWe collected the clinical records and follow-up data of patients with malignant portal obstruction treated with percutaneous endovascular portal RFA using the Habib™ VesOpen Catheter. Procedure-related complications, improvement of symptoms, portal patency, survival, and postoperative biochemical tests were investigated.ResultsThe 31 patients enrolled in the study underwent 41 successful endovascular portal RFA procedures. Patients were divided into a portal-stenting (PS) group (n = 13), which underwent subsequent portalmore » stenting with self-expandable metallic stents, and a non-stenting (NS) group (n = 18), which did not undergo stenting. No procedure-related abdominal hemorrhage or portal rupture occurred. Postablation complications included abdominal pain (n = 26), fever (n = 13), and pleural effusion (n = 15). Improvements in clinical manifestations were observed in 27 of the 31 patients. Of the 17 patients experiencing portal restenosis, 10 underwent successful repeat RFA. The rate of successful repeat RFA was significantly higher in the NS group than in the PS group. Median portal patency was shorter in the PS group than in the NS group. No mortality occurred during the 4 weeks after percutaneous endovascular portal RFA.ConclusionsPercutaneous endovascular portal RFA is a feasible and safe therapeutic option for malignant portal obstruction. Prospective investigations should be performed to evaluate clinical efficacy, in particular, the need to evaluate the necessity for subsequent portal stenting.« less

Between 2005 and 2010, eighty-two patients (89 hips) underwent a surgical dislocation of the hip at a mean age of 30.5 years (range 14.8-51.7); 10 females and 72 males. At a mean follow-up of 7.1 years (range 5-9.6) clinical function improved significantly. 6 patients were converted to total hip arthroplasty and 3 patients underwent an arthroscopy and an additional three patients had >1mm of joint space narrowing at latest follow-up giving us a 9-year cumulative Kaplan-Meier survivorship of 86.4% (CI, 79% to 94%). Thirty-four patients underwent internal fixation removal at a mean of 12.0 months (range 0.3-40.8 months). Although effective in the treatment of early hip disease, the surgical dislocation approach carries a high re-operation rate for removal of internal fixation; consequently, less invasive approaches should be considered for less complex deformities.

To determine if dexamethasone could be a suitable option in the treatment of patients with unexplained infertility. This study was carried out in the Obstetrics Department of Amir University Hospital, Semnan, Iran, from April 2001 to May 2008. One hundred and twenty-four cases of unexplained infertility that underwent ovulation induction and intrauterine insemination (IUI) (only one cycle) were evaluated, and divided into 2 groups. Sixteen cases were excluded, as they were unresponsive to the induction ovulation regimen. Group I (n=42) received clomiphene citrate (CC) + dexamethasone, and the control group (group II, n=66) received CC alone. These groups were the same in age, duration of infertility, and body mass index. The clinical pregnancy rates were evaluated in 2 groups by using statistical tests. The clinical pregnancy rate was 21.4% in group I, and 4.5% in group II. There was a significant statistical difference between the groups (relative risk=4.71, 95% confidence interval=1.35-16.42, p=0.0085). The pregnancy rate in women with unexplained infertility that underwent ovulation induction with CC + dexamethasone + IUI was significantly higher than those who underwent ovulation induction with CC alone + IUI.

Information on the prevalence of deleterious BRCA1 and BRCA2 (BRCA1/2) mutations in clinic-based populations of Black women is limited. In order to address this gap, we performed a retrospective study to determine the prevalence of deleterious BRCA1/2 mutations, predictors of having a mutation, and acceptance of risk-reducing surgeries in Black women. In an urban unselected clinic-based population, we evaluated 211 self-identified Black women who underwent genetic counseling for hereditary breast–ovarian cancer syndrome. BRCA1/2 mutations were identified in 13.4 % of the participants who received genetic testing. Younger age at diagnosis, higher BRCA-PRO score, significant family history, and diagnosis of triple-negative breast cancer were associated with identification of a BRCA1/2 mutation. Of the affected patients found to have a deleterious mutation, almost half underwent prophylactic measures. In our study population, 1 in 7 Black women who underwent genetic testing harbored a deleterious BRCA1/2 mutation independent of age at diagnosis or family history. PMID:26250392

The purpose of this study was to compare the clinical outcomes of elderly hip fracture patients who received surgical treatment with those who received non-surgical treatment. This retrospective study involved 2,756 elderly patients with hip fractures who were admitted over a six-year period. The patients' biodata, complications, ambulatory status at discharge and length of hospital stay were obtained from the institution's hip fracture registry. Among the 2,756 hip fracture patients, 2,029 (73.6%) underwent surgical intervention, while 727 (26.4%) opted for non-surgical intervention. The complication rate among the patients who underwent surgical intervention was 6.6%, while that among the patients who underwent non-surgical intervention was 12.5% (p < 0.01). The mean length of hospital stay for the surgical and non-surgical hip fracture patients was 15.7 days and 22.4 days, respectively (p < 0.01). Surgical management of hip fractures among the elderly is associated with a lower complication rate, as well as a reduced length of hospital stay. Copyright: © Singapore Medical Association

Self-expandable metal stents are often used to treat obstructive large bowel cancers. This study assessed the safety and efficacy of colonic stent insertion carried out in a district general hospital. Methods A retrospective review was carried out between 1 January 2007 and 28 February 2014 to identify patients who underwent stent insertion for malignant colorectal obstruction. Results Seventy-five patients (median age 75.2 years, 70.6% male) with primary colorectal cancer underwent stent insertion - 53 underwent semi-elective self-expanded metal stent insertion (for subacute bowel obstruction) and 22 had emergency stent inserted (for acute bowel obstruction). The majority (88%) had self-expanded metal stents inserted for palliation. Technical and clinical success rates were 98.7% and 91.2%, respectively. One patient had stent-related perforation; there was no procedure-related mortality. Conclusion This study shows that self-expanded metal stent insertion in malignant colorectal obstruction is safe and effective and can be successfully delivered in a district general hospital with high technical and clinical success rates.

To evaluate the ovarian response cycles of IVF-ET in patients who previously underwent laparoscopic cystectomy for endometriomas. Retrospective study with prospective selection of participants and controls. Instituto de Ginecología y Fertilidad Buenos Aires, Argentina. Thirty-nine patients underwent an operation for ovarian endometriomas by atraumatic removal of the pseudocapsule with minimal bipolar cauterization of small bleeders and an IVF-ET cycle (group A) and 39 control patients of similar age underwent an IVF-ET cycle for tubal factor infertility (group B). Laparoscopic endometrioma cystectomy, IVF-ET cycle. E(2) levels, number of gonadotropin ampoules, follicles, oocytes retrieved, number and quality of embryos transferred, and clinical pregnancy rate. There were no differences in all the parameters studied (E(2) levels, number of follicles, oocytes retrieved, number and quality of embryos transferred, and clinical pregnancy rate) except for the number of gonadotropin ampoules needed for ovarian hyperstimulation, which was significantly higher in group A than in group B. Our results indicate that laparoscopic cystectomy for endometriomas is an appropriate treatment since it did not negatively affect the ovarian response for IVF-ET.

We clinically investigated 34 patients with obstructive colorectal cancer who underwent placement of a colonic stent as a bridge to surgery(BTS), focusing on endoscopic findings after stent placement.Twenty -nine patients(85.3%)underwent colonoscopy after stent placement, and the entire large intestine could be observed in 28(96.6%).Coexisting lesions were observed in 22(78.6%)of these 28 patients.The lesions comprised adenomatous polyps in 17 patients(60.7%), synchronous colon cancers in 5 patients(17.9%), and obstructive colitis in 3 patients(10.7%), with some overlapping cases.All patients with multiple cancers underwent one-stage surgery, and all lesions were excised at the same time.Colonoscopy after colonic stent placement is important for preoperative diagnosis of coexisting lesions and planning the extent of resection. These considerations support the utility of colonic stenting for BTS.

Cognitive insight, a recently developed insight measure, refers to metacognitive processes of the re-evaluation and correction of distorted beliefs and misinterpretations. However, to the best of the authors' knowledge, no study has specifically examined cognitive insight, demographics, psychopathological variables, and distorted beliefs in OCD. The aim of this research was to examine links between cognitive insight and demographics, clinical factors, and distorted beliefs among patients with OCD. Eighty-four consecutive outpatients with a diagnosis of OCD underwent a detailed clinical assessment for OCD, including the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS), Beck Cognitive Insight Scale (BCIS), Thought-Action Fusion Scale (TAFS), White Bear Thought Suppression Inventory, Metacognition Questioniarre-30 (MCQ-30), and a sociodemographic questionnaire. In addition, 82 control subjects matched for age, education, and gender were tested. BCIS-self-certainty scores were all substantially higher in subjects with remitted and unremitted OCD than in healthy comparison subjects, while BCIS-composite scores were significantly lower in both patient groups than controls. Obsession and compulsion severity had significant effects on BCIS scores. In addition, it was found that the specific symptoms were linked to self-certainty scores. Self-reflectiveness and composite scores had positive correlations with the sub-scale scores of the MCQ-30, while the TAF-morality score was positively correlated with self-certainty scores. The results demonstrated poor cognitive insight among remitted and unremitted OCD patients. In addition, the present study suggested significant associations between sociodemographic and clinical features and dysfunctional appraisals. Cognitive-behavioural techniques aimed at enhancing cognitive insight may be beneficial for patients with OCD, particularly patients who have prominent dysfunctional beliefs.

Objective: To analyze clinical and prognostic variables of Oral Squamous Cell Carcinoma (OSCC) cases from the indigenous population of Karachi and to correlate with the common risk factor of tobacco habit. Methods: The study was conducted at Ziauddin University, Karachi. One hundred fifty OSCC cases were collected from the Oncology Department of Ziauddin University Hospital, North Nazimabad, Karachi and Otolaryngology ward of Civil Hospital, Karachi, during 2011 and 2015. The reporting included demographic details and variables like intra-oral subsites, clinical stage and histological grade. Recurrence of tumor after initial resection was also documented. Results: The patient’s population comprised of 98 males and 52 females. The mean age was 47.1± 12.22 (range:20-78 years). Maximum numbers were seen in the 41–50 years age group. Urdu-speaking community was the most affected ethnic group (n=75). Clinico-pathological analysis revealed that majority of cases were moderately differentiated (59%) and were either clinical stage II (35%) or IV (29%) tumors. The most common intra-oral subsite came out to be buccal mucosa of cheeks (56%) followed by lateral borders of tongue (21%), lips (13%), alveolar (6%), palate (2.6%) floor of mouth (1.3%), etc. Recurrence was observed in 08 out of 150 cases. All patients underwent primary resection±neck dissection and reconstruction where possible. Conclusions: Overall experience with oral squamous cell carcinoma shows that it has a high tendency for local invasion as well as dissemination to regional lymph nodes, i.e. cervical lymph nodes, both are associated with a poor prognosis. Preventable risk factor of tobacco chewing has been observed in majority of these cases. PMID:27375712

Polycystic ovary syndrome (PCOS) is a significant risk factor for premenopausal endometrial cancer (EC) and/or atypical endometrial hyperplasia (AEH). The aim was to elucidate the clinical background and detailed menstrual history of EC and/or AEH in young women with PCOS. From January 2001 to December 2013, women under 35 years of age who had been diagnosed with EC and/or AEH and who had been treated at Kumamoto University Hospital, Japan, were recruited. The patients' clinical characteristics, clinical stages of EC and/or AEH, medication and operation methods, endocrine profiles, and menstrual history were assessed retrospectively. Of all the cases of EC and/or AEH, 25 (4.6%) were under 35 years of age. The mean age was 29.0 years and all the patients were nulligravida. The clinical stages of EC and/or AEH that were identified included: AEH (five cases), stage IA (18 cases), IB (one case), and IIIA (one case). Fourteen (56%) cases met the criteria for PCOS. Both the Body Mass Index and Homeostatic Model Assessment-insulin resistance were significantly higher in the patients with PCOS than in the patients without PCOS. Medroxyprogesterone acetate therapy was not effective for the patients with PCOS and they underwent a hysterectomy more often than the patients without PCOS. All the patients with PCOS exhibited irregular menstruation or amenorrhea, the mean duration of which was 13.1 years before PCOS and EC and/or AEH were diagnosed. Although both the patients with and without PCOS had irregular menstruation, the patients with PCOS were less likely to have fertility-sparing surgery than the patients without PCOS because they had more advanced disease or failed to respond to medroxyprogesterone acetate therapy.

Interposition grafts combined with anterior plating currently remain the gold standard for anterior cervical discectomy and fusion. The use of anterior plates increases fusion rates but may be associated with higher rates of postoperative dysphagia. The aim of the current study was to determine the clinical and radiological outcomes following anterior cervical discectomy and fusion (ACDF) using zero-profile anchored spacers versus standard interposition grafts with anterior plating. This was a retrospective case series. A total of 53 male and 51 female consecutive patients (164 total operated levels) who underwent ACDF between 2007 and 2011 were included. The mean clinical follow-up was 15.7 ± 1.2 (SEM) months for patients with zero-profile implants and 14.8 ± 2.1 months for patients with conventional ACDF with anterior plating. Patient demographics, operative details, clinical outcomes, complications, and radiographic imaging were reviewed. Dysphagia was determined using the Bazaz criteria. Clinical outcome scores improved in both groups as measured by the modified Japanese Orthopedic Association and Nurick scores. Zero-profile constructs gave rise to significantly less prevertebral soft tissue swelling compared to constructs with anterior plates postoperatively (15.74 ± 0.52 as compared to 20.48 ± 0.85 mm, p < 0.001) and at the latest follow-up (10.88 ± 0.39 mm vs. 13.72 ± 0.67 mm, p < 0.001). There was a significant difference in the incidence of dysphagia at the latest follow-up (1.5% vs. 20%, p=0.001, zero-profile vs. anterior plate, respectively). Zero-profile implants lead to functional outcomes similar to standard anterior plate constructs. Avoiding the use of an anterior locking plate may decrease the risk of persistent postoperative dysphagia.

In rare cases, patients with Alzheimer disease (AD) present at an early age and with a family history suggestive of an autosomal dominant mode of inheritance. Mutations of the presenilin-1 (PSEN1) gene are the most common causes of dementia in these patients. Early-onset and particularly familial AD patients frequently present with variable non-amnestic cognitive symptoms such as visual, language or behavioural changes as well as non-cognitive, e.g. motor, symptoms. To investigate the phenotypic variability in carriers of the PSEN1 S170F mutation. We report a family with 4 patients carrying the S170F mutation of whom 2 underwent detailed clinical examinations. We discuss our current findings in the context of previously reported S170F cases. The clinical phenotype was consistent regarding initial memory impairment and early onset in the late twenties found in all S170F patients. There were frequent non-amnestic cognitive changes and, at early stages of the disease, indications of a more pronounced disturbance of visuospatial abilities as compared to face and object recognition. Non-cognitive symptoms most often included myoclonus and cerebellar ataxia. A review of the available case reports indicates some phenotypic variability associated with the S170F mutation including different constellations of symptoms such as parkinsonism and delusions. The variable clinical findings associated with the S170F mutation highlight the relevance of atypical phenotypes in the context of research and under a clinical perspective. CSF sampling and detection of Aβ species may be essential to indicate AD pathology in unclear cases presenting with cognitive and motor symptoms at a younger age. © 2018 S. Karger AG, Basel.

OBJECTIVE: To compare the efficacy of, and complications associated with, vasectomies performed in two medical clinics. DESIGN: Retrospective cohort study. SETTING: A private medical clinic and a family planning clinic at a teaching hospital in the Quebec City region, where one doctor performs all surgery. PARTICIPANTS: The 1223 men who underwent a first vasectomy between January 1994 and February 1996. INTERVENTIONS: Isolations of the vas deferens through the scrotum was performed using the no-scalpel technique in both clinics. At the private clinic (n = 775), vasectomy was performed by ligature with tantalum clips. At the family planning clinic (n = 448), a combination of cauterisation of the abdominal end of the vas deferens, leaving the testicular end open, and fascial interposition with a clip was used. MAIN OUTCOME MEASURES: Rate of postoperative complications (painful granuloma; noninfectious inflammation of the vas deferens, epididymis, and testes; hematoma; infection; undiagnosed pain) and rate of recanalization (early and late). RESULTS: At the private clinic, 39 patients (5.0%) consulted for postoperative complications, compared with 55 patients (12.3%) at the family planning clinic (chi (2)1 = 21.0; P < 0.001). Of the patients who underwent semen analysis, 15 (2.8%) at the private clinic and 4 (1.2%) at the family planning clinic experienced early or late recanalization (chi (2)1 = 2.2; P < .14). CONCLUSION: The rate of consultation for postoperative complications was lower at the private clinic than at the family planning clinic, but the efficacy of the procedure appeared to be higher at the family planning clinic. The surgical techniques used at the two clinics might partially explain these differences. PMID:9789666

Curettage of the cyst and bone grafting are the most common methods used in the treatment of unicameral bone cysts (UBC) and aneurysmal bone cysts (ABC). Recurrence of these cysts is often associated with insufficient curettage of the cyst during surgery. In this study, we aimed to evaluate the effect of insufficient curettage on recurrence in patients with UBC and ABC. The retrospective study included 18 patients with UBC and 14 patients with ABC that were surgically treated by curettage and bone grafting in our clinic between 2006-2013. Mean age was 19.80 (range, 4-50) years in the patients with UBC and 21.76 (range, 4-56) in the patients with ABC. The diagnosis of the cysts was established both clinically and radiologically. Mean follow-up period was 36 (range, 6-60) months both in the patients with UBC and ABC. The patients with recurrence underwent a second curettage and grafting procedure. Healing and recurrence were evaluated according to modified Neer's scale. Recurrence occurred in 8 patients. Of these, 5 patients underwent a second curettage and grafting procedure and 3 patients were lost to follow-up. Complete healing occurred in all the patients that underwent a second curettage and grafting procedure. The achievement of complete healing in the patients that underwent a second curettage and grafting procedure indicates that the recurrence of UBC and ABC is associated with insufficient curettage.

To compare the clinical accuracy of two different continuous glucose sensors (CGS) during euglycemia and hypoglycemia using continuous glucose-error grid analysis (CG-EGA). FreeStyle Navigator (Abbott Laboratories, Alameda, CA) and MiniMed CGMS (Medtronic, Northridge, CA) CGSs were applied to the abdomens of 16 type 1 diabetic subjects (age 42 +/- 3 years) 12 h before the initiation of the study. Each system was calibrated according to the manufacturer's recommendations. Each subject underwent a hyperinsulinemic-euglycemic clamp (blood glucose goal 110 mg/dl) for 70-210 min followed by a 1-mg.dl(-1).min(-1) controlled reduction in blood glucose toward a nadir of 40 mg/dl. Arterialized blood glucose was determined every 5 min using a Beckman Glucose Analyzer (Fullerton, CA). CGS glucose recordings were matched to the reference blood glucose with 30-s precision, and rates of glucose change were calculated for 5-min intervals. CG-EGA was used to quantify the clinical accuracy of both systems by estimating combined point and rate accuracy of each system in the euglycemic (70-180 mg/dl) and hypoglycemic (<70 mg/dl) ranges. A total of 1,104 data pairs were recorded in the euglycemic range and 250 data pairs in the hypoglycemic range. Overall correlation between CGS and reference glucose was similar for both systems (Navigator, r = 0.84; CGMS, r = 0.79, NS). During euglycemia, both CGS systems had similar clinical accuracy (Navigator zones A + B, 88.8%; CGMS zones A + B, 89.3%, NS). However, during hypoglycemia, the Navigator was significantly more clinically accurate than the CGMS (zones A + B = 82.4 vs. 61.6%, Navigator and CGMS, respectively, P < 0.0005). CG-EGA is a helpful tool for evaluating and comparing the clinical accuracy of CGS systems in different blood glucose ranges. CG-EGA provides accuracy details beyond other methods of evaluation, including correlational analysis and the original EGA.

The diagnostic yield of various neurophysiological criteria may vary in different subforms of Guillain-Barre syndrome (GBS), whose prevalence varies in different geographical areas. To evaluate the sensitivity of various neurophysiological criteria in different clinical subtypes of GBS, and their relationship with severity, duration and outcome. Consecutive patients with GBS underwent detailed clinical evaluation. Severity was graded on a scale from 0 to 10. Motor and sensory nerve conductions and F wave studies were performed. The diagnostic sensitivity of Albers et al (set 1), Cornblath (set 2), Ho et al (set 3), Dutch GBS study group (set 4), Italian GBS study group (set 5) and Albers and Kelly (set 6) criteria were evaluated and correlated with clinical subtypes of GBS, duration, severity and outcome. There were 51 patients. Mean disability was 6.8; 34 patients were bedridden and five needed a ventilator. Clinical presentation was pure motor in 31, motorsensory in 18 and pure sensory in two patients. The sensitivity of nerve conduction study in the diagnosis of GBS was highest in set 1 (88.2%) followed by set 3 (86.3%) and set 4 (82.4%) and lowest in set 2 (39.2%). The diagnostic yield of sets 1, 3 and 4 were also higher than sets 2, 5 and 6 in different clinical subtypes of GBS. As per Ho et al, patients could be categorised into acute inflammatory demyelinating polyradiculoneuropathy (44 (86.3%)), acute motor axonal neuropathy (4 (7.8%)) and acute motor sensory axonal neuropathy (3 (5.9%)). One (2%) patient died, 22.4% had complete, 57.1% partial and 18.4% poor recovery at 3 months. Outcome was related to severity of illness and compound muscle action potential (CMAP) amplitude. The sensitivity of different neurophysiological criteria in the diagnosis of Indian GBS patients varied from 39.2% to 88.2%. The outcome was related to severity of illness and CMAP amplitude.

The purpose of this report is to present documenting evidence of the clinical readiness of an abdominal left ventricular assist device (ALVAD) according to NHLI criteria,‡ and the initiation of clinical trials of this device in otherwise irretrievable adult post-cardiotomy patients at the Texas Heart Institute of St. Luke's Episcopal and Texas Children's Hospitals. The ALVAD system has been developed, modified, and improved under NHLI auspices over the last eight years,‡‡ with annual reviews. Over 20,000 hours of in-vivo testing in the calf have been accomplished in our laboratories. The current clinical trials underwent two federal reviews (May 22, 1973 and October 17, 1974) and were the topic of an Ad Hoc Workshop at NHLI on October 28, 1973.‡‡‡ More recently, a consecutive series of 26 bovine ALVAD implantations were undertaken; acute and chronic hemodynamic effectiveness with maintenance or augmentation of the systemic circulation during profound ventricular unloading without undue blood trauma, intra-or extra-prosthetic thrombosis, or sepsis was demonstrated; no biomaterials problems were encountered. In-vivo realibility and durability, histologic and pathologic results were detailed, summarized, and submitted to NHLI. Patient acceptability surveys and geometric and volumetric human configuration studies were analyzed. Categorizations of the patients at risk in our institutions and the needs for such a device were documented. The periods of intended use (two weeks-one month), weaning procedures, and the possibility of pump dependence have been discussed. The legal, moral, ethical and informed consent issues were addressed. Clinical protocols (anesthesia, surgical, cardiologic, hematologic, engineering, computerized data-acquisition, follow-up) and cost analyses were developed. The device has now been used in four terminal patients since December, 1975; all subsequently succumbed, but their circulations were temporarily supported during total left ventricular unloading for periods up to eight hours. Continued systematic, controlled clinical investigations of this nature are warranted. A comprehensive listing of pertinent references is included. Images PMID:15216148

We performed 99Tcm-ethyl cysteinate dimer (ECD) interictal single photon emission tomography (SPET) in 26 children with severe therapy-resistant epilepsy. All the children underwent a detailed clinical examination, an electroencephalogram (EEG) investigation and brain magnetic resonance imaging (MRI). In 21 of the 26 children, SPET demonstrated brain blood flow abnormalities, in 13 cases in the same territories that showed EEG alterations. MRI showed structural lesions in 6 of the 26 children, while SPET imaging confirmed these abnormalities in only 5 children. The lesion not detected on SPET was shown to be 3 mm thick on MRI. Five symptomatic patients had normal SPET. In one of these patients, the EEG findings were normal and MRI revealed a small calcific nodule (4 mm thick); in the others, the EEG showed non-focal but diffuse abnormalities. These data confirm that brain SPET is sensitive in detecting and localizing hypoperfused areas that could be associated with epileptic foci in this group of patients, even when the MRI image is normal.

Our purpose is to report on the epidemiological variables and their association with the results of the exercise tolerance test (ETT) in the series of patients referred for standard diagnostic ETT at Seremban Hospital during the year 2001. ETT is widely performed, but, in Malaysia, an analysis of the associations between the epidemiological data and the results of the ETT has not been presented. All patients referred for ETT at Seremban Hospital who underwent exercise treadmill tests for the year 2001 were taken as the study population. Demographic details and patients with established heart disease (i.e. prior coronary bypass surgery, myocardial infarction, or congestive heart failure) were noted. Clinical and ETT variables were collected retrospectively from the hospital records. Testing and data management were performed in a standardized fashion with a computer-assisted protocol. This study showed that there was no significant predictive epidemiological variable on the results of the ETT. However, it was found that there was statistically significant difference between the peak exercise time of males and females undergoing the ETT. PMID:22973128

Tinnitus is the perception of sound with no external stimulus and idiopathic subjective tinnitus is the most common type in adults. Mean platelet volume (MPV) alterations were shown in some inflammatory diseases and were evaluated as a clinically useful marker. Our aim was to investigate MPV alterations in idiopathic subjective tinnitus patients. A total of 101 patients and 54 age- and sex-matched healthy control subjects were enrolled in the study. Patients included in the study had complaints of tinnitus for at least 3 months. All patients underwent detailed otolaryngologic examination, blood sampling, pure tone audiometry, magnetic resonance imaging of ear, and vertebrobasilar artery Doppler ultrasonography to make the differential diagnosis of tinnitus. Blood sampling consisted of renal-liver-thyroid function tests, lipid profile, and complete blood count. All tests and examinations except the imaging modalities were also performed for the control group. There were no differences in age and sex distribution of groups. Mean platelet volume values were significantly increased in tinnitus patients when compared with controls (p = 0.001). We think that MPV can be qualified as a useful marker in tinnitus patients.

Sheng-Ling, Jan; Hwang, Betau; Lee, P.-C.

Purpose: Accurate evaluation of the size, location and adjacent structure of an atrial septal defect (ASD) is very important in the selection of patients for further management. We directly compared the utility of transthoracic echocardiography, angiocardiography, balloon sizing, and intracardiac ultrasound (ICUS) in the detection of ASD.Methods: Twenty-one children underwent an ICUS study of ASD after routine clinical and laboratory studies. All patients had received transthoracic echocardiography (TTE), cardiac catheterization, cineangiography, and balloon sizing before the ICUS to evaluate the ASD.Results: There was a significant correlation between the ICUS-derived ASD diameter and the other methods (p < 0.001). The balloon-sizingmore » diameter was estimated by the equation: TTE diameter x 1.09 + 3.9 mm. There was a good correlation between the predicted and measured balloon-sizing diameter (r = 0.963; p < 0.001).Conclusion: It is worthwhile spending a few minutes to perform ICUS during cardiac catheterization since it will provide more detailed information on and high resolution images of atrial septal morphology, especially for patients undergoing transcatheter closure by device.« less

Purpose To determine the sensitivity and specificity of orbital ultrasonography in distinguishing papilledema from pseudopapilledema in adult patients. Methods The records of all adult patients referred to the neuro-ophthalmology service who underwent orbital ultrasonography for the evaluation of suspected papilledema were reviewed. The details of history, ophthalmologic examination, and results of ancillary testing including orbital ultrasonography, MRI, and lumbar puncture were recorded. Results of orbital ultrasonography were correlated with the final diagnosis of papilledema or pseudopapilledema on the basis of the clinical impression of the neuro-ophthalmologist. Ultrasound was considered positive when the optic nerve sheath diameter was ≥3.3 mm along with a positive 30° test. Results The sensitivity of orbital ultrasonography for detection of papilledema was 90% (CI: 80.2–99.3%) and the specificity in detecting pseudopapilledema was 79% (CI: 67.7–90.7%). Conclusions Orbital ultrasonography is a rapid and noninvasive test that is highly sensitive, but less specific in differentiating papilledema from pseudopapilledema in adult patients, and can be useful in guiding further management of patients in whom the diagnosis is initially uncertain.

A pilot study evaluating alternative approaches of academic detailing in rural family practice clinics

PubMed Central

2012-01-01

Background Academic detailing is an interactive, convenient, and user-friendly approach to delivering non-commercial education to healthcare clinicians. While evidence suggests academic detailing is associated with improvements in prescribing behavior, uncertainty exists about generalizability and scalability in diverse settings. Our study evaluates different models of delivering academic detailing in a rural family medicine setting. Methods We conducted a pilot project to assess the feasibility, effectiveness, and satisfaction with academic detailing delivered face-to-face as compared to a modified approach using distance-learning technology. The recipients were four family medicine clinics within the Oregon Rural Practice-based Research Network (ORPRN). Two clinics were allocated to receive face-to-face detailing and two received outreach through video conferencing or asynchronous web-based outreach. Surveys at midpoint and completion were used to assess effectiveness and satisfaction. Results Each clinic received four outreach visits over an eight month period. Topics included treatment-resistant depression, management of atypical antipsychotics, drugs for insomnia, and benzodiazepine tapering. Overall, 90% of participating clinicians were satisfied with the program. Respondents who received in person detailing reported a higher likelihood of changing their behavior compared to respondents in the distance detailing group for five of seven content areas. While 90%-100% of respondents indicated they would continue to participate if the program were continued, the likelihood of participation declined if only distance approaches were offered. Conclusions We found strong support and satisfaction for the program among participating clinicians. Participants favored in-person approaches to distance interactions. Future efforts will be directed at quantitative methods for evaluating the economic and clinical effectiveness of detailing in rural family practice settings. PMID:23276303

AIM To show outcomes of our series of patients that underwent a total gastrectomy with a robotic approach and highlight the technical details of a proposed solution for the reconstruction phase. METHODS Data of gastrectomies performed from May 2014 to October 2016, were extracted and analyzed. Basic characteristics of patients, surgical and clinical outcomes were reported. The technique for reconstruction (Parisi Technique) consists on a loop of bowel shifted up antecolic to directly perform the esophago-enteric anastomosis followed by a second loop, measured up to 40 cm starting from the esojejunostomy, fixed to the biliary limb to create an enteroenteric anastomosis. The continuity between the two anastomoses is interrupted just firing a linear stapler, so obtaining the Roux-en-Y by avoiding to interrupt the mesentery. RESULTS Fifty-five patients were considered in the present analysis. Estimated blood loss was 126.55 ± 73 mL, no conversions to open surgery occurred, R0 resections were obtained in all cases. Hospital stay was 5 (3-17) d, no anastomotic leakage occurred. Overall, a fast functional recovery was shown with a median of 3 (3-6) d in starting a solid diet. CONCLUSION Robotic surgery and the adoption of a tailored reconstruction technique have increased the feasibility and safety of a minimally invasive approach for total gastrectomy. The present series of patients shows its implementation in a western center with satisfying short-term outcomes. PMID:28694670

To evaluate the impact of CT perfusion imaging on the detection of peripheral chronic pulmonary embolisms (CPE). 62 patients underwent a dual-energy chest CT angiographic examination with (a) reconstruction of diagnostic and perfusion images; (b) enabling depiction of vascular features of peripheral CPE on diagnostic images and perfusion defects (20 segments/patient; total: 1240 segments examined). The interpretation of diagnostic images was of two types: (a) standard (i.e., based on cross-sectional images alone) or (b) detailed (i.e., based on cross-sectional images and MIPs). The segment-based analysis showed (a) 1179 segments analyzable on both imaging modalities and 61 segments rated as nonanalyzable on perfusion images; (b) the percentage of diseased segments was increased by 7.2 % when perfusion imaging was compared to the detailed reading of diagnostic images, and by 26.6 % when compared to the standard reading of images. At a patient level, the extent of peripheral CPE was higher on perfusion imaging, with a greater impact when compared to the standard reading of diagnostic images (number of patients with a greater number of diseased segments: n = 45; 72.6 % of the study population). Perfusion imaging allows recognition of a greater extent of peripheral CPE compared to diagnostic imaging. • Dual-energy computed tomography generates standard diagnostic imaging and lung perfusion analysis. • Depiction of CPE on central arteries relies on standard diagnostic imaging. • Detection of peripheral CPE is improved by perfusion imaging.

To describe the clinical and anatomopathologic characteristics of gallbladder polyps found in patients who underwent cholecystectomy at Clinica Anglo Americana for the 1999-2007 period. Descriptive and retrospective study that started at Pathology Department where patients with anatomopathologic finding of gallbladder polyps who underwent cholecystectomy for the 1999-2007 period were selected. Clinical records were reviewed to take ultrasonographic, anatomopathologic and clinical characteristics, which were included and studied in a data base in Microsoft Excel. Gallbladder polyps were found in 172 (10%) of 1707 gallbladders that were analized. Cholesterolosic polyps were found in 95.4% of the cases, 4% were adenomas and 0.6% were hyperplasic polyps. Gallbladder polyps ≥ 10 mm were found in 32,25% of the cases. A 90% of these polyps were cholesterolosic and a 10% were adenomas. No malign polyps were found in this study. The vast majority of gallbladder polyps, including the ≥ 10 mm group, were cholesterolosic. The physician decision to remove the gallbladder must be individualized and discussed with each patient, considering gallbladder polyp characteristics such as size and growth rate of the lesion.

While altered foot arch characteristics (high or low) are frequently assumed to influence lower limb biomechanics and are suspected to be a contributing factor for injuries, the association between arch characteristics and lower limb running biomechanics in children is unclear. Therefore, the aim of this study was to investigate the relationship between a dynamically measured arch index and running biomechanics in healthy children. One hundred and one children aged 10-14 years were included in this study and underwent a biomechanical investigation. Plantar distribution (Novel, Emed) was used to determine the dynamic arch index and 3D motion capture (Vicon) to measure running biomechanics. Linear mixed models were established to determine the association between dynamic arch index and foot strike patterns, running kinematics, kinetics and temporal-spatial outcomes. No association was found between dynamic arch index and rate of rearfoot strikes (p = 0.072). Of all secondary outcomes, only the foot progression angle was associated with the dynamic arch index (p = 0.032) with greater external rotation in lower arched children. Overall, we found only few associations between arch characteristics and running biomechanics in children. However, altered foot arch characteristics are of clinical interest. Future studies should focus on detailed foot biomechanics and include clinically diagnosed high and low arched children. Copyright © 2018 Elsevier B.V. All rights reserved.

To examine the epidemiology of and possible risk factors for skin diseases in patients with schizophrenia. All of 337 patients with schizophrenia were recruited from the therapeutic community of a psychiatric hospital and underwent a detailed skin examination. The National Health Insurance Research Database (NHIRD) was used to compare the prevalence of skin diseases between patients with schizophrenia and those without. In the clinical survey, fungal infection (61.4%) and dermatitis (46.9%) were the most common skin diseases. Clozapine users had a lower risk of fungal infection than those on typical antipsychotics [odds ratio (OR)=0.49, 95% confidence interval (CI)=0.30-0.81]. Obese patients were more likely to have fungal infections than those without (OR=1.93, 95% CI=1.20-3.09), and those with diabetes had an increased risk of bacterial infection than those without (OR=2.0, 95% CI=1.06-3.75). NHIRD revealed that the overall prevalence of skin diseases, including infections, dermatitis, hyperkeratosis, pilosebaceous disease, androgenic alopecia, xerosis and stasis, were higher in patients with schizophrenia than in those without (75.1% vs. 72.6%, P=.01). The prevalence of skin diseases is high in patients with schizophrenia, for whom proper skin care is necessary to improve their life quality. Copyright © 2014 Elsevier Inc. All rights reserved.

Background Treatment-resistant depression presents a serious challenge to both patients and clinicians. The anterior and midlateral prefrontal cortices play complementary roles in integrating emotional and cognitive experiences and in modulating subcortical regions. Both regions offer a distinct opportunity for targeted antidepressant treatments. We chose to pilot the safety and therapeutic benefits of chronic and intermittent epidural prefrontal cortical stimulation (EpCS) in patients with treatment-resistant depression. Methods We enrolled five adults with an average of 5.8 failed antidepressant treatments in their current depressive episode. All subjects underwent comprehensive clinical assessments, detailed neuropsychological testing, and presurgical magnetic resonance imaging. Four cortical stimulation paddle leads were stereotactically placed bilaterally over the anterior frontal poles and midlateral prefrontal cortex. We also acquired a postsurgical computed tomography scan and repeatedly assessed clinical outcomes over time of EpCS as an adjunctive treatment to constant medications. Results All patients tolerated the therapy. At 7-month follow-up, the average improvement from preimplant baseline on the Hamilton Rating Scale for Depression and the Inventory of Depressive Symptoms—Self-Report were 54.9% (± 37.7) and 60.1% (± 34.1), respectively. Three implanted subjects reached remission. One patient's left hemisphere leads were explanted 12 weeks postsurgery because of a scalp infection. Conclusions Bilateral EpCS over anterior and midlateral frontal cortex is a promising new technology for treatment-resistant depression. Future double-blind studies are warranted. PMID:19819427

We investigated the presence of femoral head avascular osteonecrosis (FHAVN) by a selective investigation with MRI at follow-up. A total of 331(200 men, 131 women) renal transplants were included. They were transplanted at the mean age of 31.4 (9-63) years. The mean follow-up time of all patients after transplantation was 60.6 (6-233) months, and the mean current age 36.6 (11-66) years. All transplants filled out a questionnaire on musculoskeletal symptoms and underwent a detailed clinical examination. Magnetic resonance imaging was done in cases of hip joint pain in groin, buttock, thigh and knee and in 50 asymptomatic transplants. FHAVN were identified according to Ficat Arlet classification. 43(13%) patients reported pain without previous trauma. In the clinical examination, limited ranges of motion of the hip were noted in 13 of them. FHAVN was detected in 11 of 43 patients. Disease was bilateral in two of the eleven patients. Of the 662 femoral heads, 43 were associated with hip pain whereas the remaining 619 were asymptomatic. Avascular osteonecrosis was not confirmed in the asymptomatic 100 hips with magnetic resonance imaging. A selective investigation of FHAVN may be used to diagnose in renal allograft recipients with painful hips at follow-up. With a retrospective selective analysis, the presence of FHAVN was low among renal transplantation recipients at the end of the study.

Objectives Hypertrophic cardiomyopathy, a primary disorder of the myocardium, is the most common cardiac disease in cats. However, determination of myocardial deformation with two-dimensional speckle-tracking echocardiography in cats with various stages of hypertrophic cardiomyopathy has not yet been reported. This study was designed to measure quantitatively multidirectional myocardial deformations of cats with hypertrophic cardiomyopathy. Methods Thirty-two client-owned cats with hypertrophic cardiomyopathy and 14 healthy cats serving as controls were enrolled and underwent assessment of myocardial deformation (peak systolic strain and strain rate) in the longitudinal, radial and circumferential directions. Results Longitudinal and radial deformations were reduced in cats with hypertrophic cardiomyopathy, despite normal systolic function determined by conventional echocardiography. Cats with severely symptomatic hypertrophic cardiomyopathy also had lower peak systolic circumferential strain, in addition to longitudinal and radial strain. Conclusions and relevance Longitudinal and radial deformation may be helpful in the diagnosis of hypertrophic cardiomyopathy. Additionally, the lower circumferential deformation in cats with severe hypertrophic cardiomyopathy may contribute to clinical findings of decompensation, and seems to be related to severe cardiac clinical signs. Indices of multidirectional myocardial deformations by two-dimensional speckle-tracking echocardiography may be useful markers and help to distinguish between cats with hypertrophic cardiomyopathy and healthy cats. Additionally, they may provide more detailed assessment of contractile function in cats with hypertrophic cardiomyopathy.

The objective of this trial is to investigate the diagnostic value of magnetic resonance imaging (MRI) with an endorectal surface coil for precise local staging of patients with histologically proven cervical cancer by comparing the radiological, clinical, and histological results. Women with cervical cancer were recruited for this trial between February 2007, and September 2010. All the patients were clinically staged according to the FIGO classification and underwent radiological staging by MRI that employed an endorectal surface coil. The staging results after surgery were compared to histopathology in all the operable patients. A total of 74 consecutive patients were included in the trial. Forty-four (59.5%) patients underwent primary surgery, whereas 30 (40.5%) patients were inoperable according to FIGO and underwent primary radiochemotherapy. The mean age of the patients was 50.6 years. In 11 out of the 44 patients concordant staging results were obtained by all three staging modalities. Thirty-two of the 44 patients were concordantly staged by FIGO and histopathological examination, while only 16 were concordantly staged by eMRI and histopathological examination. eMRI overstaged tumors in 14 cases and understaged them in 7 cases. eMRI is applicable in patients with cervical cancer, yet of no benefit than staging with FIGO or standard pelvic MRI. The most precise preoperative staging procedure still appears to be the clinical examination. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Acute appendicitis (AA) is the most common surgical disease, and appendectomy is the treatment of choice in the majority of cases. A correct diagnosis is key for decreasing the negative appendectomy rate. The management can become difficult in case of complicated appendicitis. The aim of this study is to describe the worldwide clinical and diagnostic work-up and management of AA in surgical departments. This prospective multicenter observational study was performed in 116 worldwide surgical departments from 44 countries over a 6-month period (April 1, 2016-September 30, 2016). All consecutive patients admitted to surgical departments with a clinical diagnosis of AA were included in the study. A total of 4282 patients were enrolled in the POSAW study, 1928 (45%) women and 2354 (55%) men, with a median age of 29 years. Nine hundred and seven (21.2%) patients underwent an abdominal CT scan, 1856 (43.3%) patients an US, and 285 (6.7%) patients both CT scan and US. A total of 4097 (95.7%) patients underwent surgery; 1809 (42.2%) underwent open appendectomy and 2215 (51.7%) had laparoscopic appendectomy. One hundred eighty-five (4.3%) patients were managed conservatively. Major complications occurred in 199 patients (4.6%). The overall mortality rate was 0.28%. The results of the present study confirm the clinical value of imaging techniques and prognostic scores. Appendectomy remains the most effective treatment of acute appendicitis. Mortality rate is low.

On June 2008, the European Medicines Agency (EMA) introduced changes to the Summary of Product Characteristics (SPC) for cabergoline and pergolide, to reduce the risk of cardiac valvulopathy in users of these drugs. To assess the effectiveness of EMA recommendations in Italian clinical practice, we retrospectively reviewed medical charts of patients with degenerative Parkinsonism treated with cabergoline in three large Italian clinics between January 2006 and June 2012. The prevalence and the severity of cardiac valve regurgitation were assessed in patients who stopped cabergoline therapy prior to June 2008 or continued therapy after that date. In addition, the proportion of patients undergoing echocardiographic examination in each cohort was evaluated. A total of 61 patients were available for evaluation. The proportion of patients who underwent a baseline echocardiographic examination increased from 64 % in the period before the 2008 SPC changes to 71 % among those who continued treatment after that date. However, only 18 and 29 % of patients underwent at least two echocardiographic examinations during the pre-SPC and cross-SPC change period, respectively. No severe cardiac valve regurgitation was documented in any of the study patients using cabergoline either prior or after 26th June 2008. Our findings show that the 2008 changes to the SPC resulted in an increase in physicians' awareness of cabergoline-induced valvulopathy risk in Italy. However, only a small percentage of patients underwent serial echocardiography. Further efforts are needed to achieve better compliance with the prescribing guidelines for cabergoline treated patients in clinical practice.

To report a single institution's experience with transoral robotic surgery (TORS) and its clinical outcomes. Preliminary clinical data from a prospective TORS study. University tertiary care facility. Patients who underwent TORS at The Ohio State University Medical Center. Demographic, intraoperative, clinicopathological, and follow-up functional data were collected. Sixty-four patients underwent TORS with a median age of 56.9 years. A total of 113 TORS procedures were performed. Fifty-four patients with squamous cell cancer (SCCA) were included in the final analysis. Mean follow-up time was 11.8 months (range, 2-29). There was a trend toward longer TORS setup time, operative time, estimated blood loss, and hospital length of stay with advanced (T(3)) compared with early-stage tumors (T(1-2)). There were no major intraoperative complications, and none of the procedures were aborted because of inability to remove the tumor. Negative resection margins were achieved in 93% of cases of SCCA. No patients experienced immediate postoperative complications, and all of the patients tolerated an oral diet without any airway compromise on the day of surgery. Forty-nine patients (91%) underwent adjuvant radiation therapy (RT), with 11 patients requiring gastrostomy tube placement during RT. Addition of TORS to overall management of head and neck SCCA spared adjuvant RT or combined chemotherapy and RT (CRT) in 50% of stage I/II tumors and spared chemotherapy in 34% of stage III/IV tumors. TORS is a safe procedure with minimal complications and favorable clinical and functional outcomes. It is a promising future alternative surgical treatment for laryngopharyngeal tumors.

Infection is a serious complication of left ventricular assist device (LVAD) therapy. Published data regarding LVAD-associated infections (LVADIs) are limited by single-center experiences and use of nonstandardized definitions. We retrospectively reviewed 247 patients who underwent continuous-flow LVAD implantation from January 2005 to December 2011 at Mayo Clinic campuses in Minnesota, Arizona, and Florida. LVADIs were defined using the International Society for Heart and Lung Transplantation criteria. We identified 101 episodes of LVADI in 78 patients (32%) from this cohort. Mean age (± standard deviation [SD]) was 57±15 years. The majority (94%) underwent Heartmate II implantation, with 62% LVADs placed as destination therapy. The most common type of LVADIs were driveline infections (47%), followed by bloodstream infections (24% VAD related, and 22% non-VAD related). The most common causative pathogens included gram-positive cocci (45%), predominantly staphylococci, and nosocomial gram-negative bacilli (27%). Almost half (42%) of the patients were managed by chronic suppressive antimicrobial therapy. While 14% of the patients had intraoperative debridement, only 3 underwent complete LVAD removal. The average duration (±SD) of LVAD support was 1.5±1.0 years. At year 2 of follow-up, the cumulative incidence of all-cause mortality was estimated to be 43%. Clinical manifestations of LVADI vary on the basis of the type of infection and the causative pathogen. Mortality remained high despite combined medical and surgical intervention and chronic suppressive antimicrobial therapy. Based on clinical experiences, a management algorithm for LVADI is proposed to assist in the decision-making process.

Few studies have assessed the effect of Chiari malformation type 1 (CM-1) surgical decompression on cervical lordosis and range of motion (ROM). We aimed to assess the effect of expansile duraplasty on postoperative cervical mobility and spinal stability. This was a single-center retrospective review of prospectively collected data. Patients were included if they underwent surgical treatment for symptomatic CM-1 between the years 1999 and 2009. Cervical ROM and lordosis were assessed before and after surgery in all patients. Collected data also included clinical improvement, as well as surgical complications after the procedure. Patients were divided into 2 groups. The first group underwent a posterior fossa bony decompression alone, while the second group additionally received an expansile duraplasty. Patients were further subdivided into 3 subgroups on the basis of the severity of tonsillar herniation. A total of 76 patients fit our selection criteria. Fifty-five patients belonged to the duraplasty group. Twenty-one patients underwent bony decompression alone. The 2 groups were statistically demographically and clinically similar. There was no difference in clinical outcome or in ROM and cervical lordosis between the groups except for patients with severe tonsillar herniation (CM-I grade 3). These patients had a statistically significant improvement in their postoperative cervical motility without compromising their spinal stability. Adding an expansile duraplasty to craniovertebral decompression in CM-1 patients with severe tonsillar herniation may restore cervical ROM while preserving stability and alignment. This may relieve postoperative pain and improve clinical prognosis. Copyright © 2016 Elsevier Inc. All rights reserved.

The clinical course and management of 40 patients who underwent operation for acute cholecystitis developing as a postoperative complication were reviewed. Of note was the mortality of 47%, the high incidence of gangrene, perforation, empyema, and cholangitis, and the atypical clinical presentation of acute cholecystitis under these conditions. Awareness of this possible complication, knowledge of its clinical features, and early surgical intervention are important facets of successful management. PMID:952563

The goal of this study was to describe the clinical characteristics of pediatric patients with lone atrial fibrillation (LAF) and their treatment outcomes. The authors focused on patients who underwent ablation and compared the recurrence after ablation of supraventricular tachycardia substrates as presumed triggers versus pulmonary vein isolation (PVI). LAF in pediatrics is rare, and outcomes remain poorly defined. Current guidelines on ablation are based on a few small studies, and we present outcomes from the largest cohort of patients after ablation. This retrospective review included patients ≤21 years of age diagnosed with LAF from 2004 to 2015. Relevant clinical data, including recurrence rates after treatment, were tracked and analyzed with a focus on patients who underwent ablation procedures. Sixty-two patients were identified with LAF; 88% were male, and 63% were athletes. Of the 33 patients taking antiarrhythmic medication, 20 (61%) experienced recurrence. Overall, 16 patients (26%) underwent ablation: PVI in 10 (62.5%), ablation of an accessory pathway in 3 (19%), and modification of the slow atrioventricular nodal pathway in 3 (19%). One-half of patients who underwent PVI experienced documented recurrence. Of those who solely underwent supraventricular tachycardia substrate ablation, one-half also had symptomatic or documented recurrence. Ablation recurrence within this pediatric cohort was higher than expected. These recurrence rates may be demonstrative of the technical challenge of pediatric ablation compared with adult counterparts, characteristics of these patients such as athletic conditioning, or inherent differences in their atrial tissue, rendering it more refractory to substrate modification.

Background: The minimal repair technique for sports hernias repairs only the weak area of the posterior abdominal wall along with decompressing the genitofemoral nerve. This technique has been shown to return athletes to competition rapidly. This study compares the clinical outcomes of the minimal repair technique with the traditional modified Bassini repair. Hypothesis: Athletes undergoing the minimal repair technique for a sports hernia would return to play more rapidly compared with athletes undergoing the traditional modified Bassini repair. Methods: A retrospective study of 28 patients who underwent sports hernia repair at the authors’ institution was performed. Fourteen patients underwent the modified Bassini repair, and a second group of 14 patients underwent the minimal repair technique. The 2 groups were compared with respect to time to return to sport, return to original level of competition, and clinical outcomes. Results: Patients in the minimal repair group returned to sports at a median of 5.6 weeks (range, 4-8 weeks), which was significantly faster compared with the modified Bassini repair group, with a median return of 25.8 weeks (range, 4-112 weeks; P = 0.002). Thirteen of 14 patients in the minimal repair group returned to sports at their previous level, while 9 of 14 patients in the Bassini group were able to return to their previous level of sport (P = 0.01). Two patients in each group had recurrent groin pain. One patient in the minimal repair group underwent revision hernia surgery for recurrent pain, while 1 patient in the Bassini group underwent hip arthroscopy for symptomatic hip pain. Conclusion: The minimal repair technique allows athletes with sports hernias to return to play faster than patients treated with the modified Bassini. PMID:24427419

The clinical presentation, management and outcome of all patients with bile duct injury who presented to our tertiary care centre at various stages after cholecystectomy were analyzed. The patients were categorized into three groups: group A-patients in whom the injury was detected during cholecystectomy, group B-patients who presented within 2 weeks of cholecystectomy and group C-patients who presented after 2 weeks of cholecystectomy. Our team acted as rescue surgeons and performed 'on-table' repair for injuries occurring in another unit or in another hospital. Strasberg classification of bile duct injury was followed. In group A, partial and complete transections were managed by repair over T-tube and high hepaticojejunostomy, respectively. Patients in group B underwent endoscopic retrograde cholangiogram and/or magnetic resonance cholangiogram to evaluate the biliary tree. Those with intact common bile duct underwent endoscopic papillotomy and stenting in addition to drainage of intra-abdominal collection when present. For those with complete transection, early repair was considered if there was no sepsis. In presence of intra-abdominal sepsis an attempt was made to create controlled external biliary fistula. This was followed by hepatico jejunostomy at least after 3 months. Group C patients underwent hepaticojejunostomy at least 6 weeks after the injury. The outcome was graded into three categories: grade A-no clinical symptoms, normal LFT; grade B-no clinical symptoms, mild derangement of LFT or occasional episodes of pain or fever; grade C-pain, cholangitis and abnormal LFT; grade D-surgical revision or dilatation required. Fifty nine patients were included in the study and the distribution was group A-six patients, group B-33 patients and group C-20 patients. In group A, one patient with complete transection of the right hepatic duct (type C) and partial injury to left hepatic duct (LHD) underwent right hepaticojejunostomy and repair of the LHD over stent. Two patients with type D and three patients with type E 2 injury underwent repair over T-tube and hepaticojejunostomy, respectively. In group B, all except one of the 18 patients with type A injury underwent endoscopic papillotomy and stenting. The bile leak subsided at a mean interval of 8 days in all, except one patient who died of fulminant sepsis. Of the 15 patients with type E injury, five underwent hepaticojejunostomy after a minimum gap of 3 months. Early repair was considered in 10 patients. Twenty patients in group C underwent hepaticojejunostomy. In a mean follow-up of 40 months, the outcome was grade A in 54 patients, grade B in three patients (one from each of the three groups) and grade D in one patient (group C). The latter patient with a type E3 injury developed recurrent stricture and cholangitis necessitating percutaneous transhepatic dilatation. The high success rate of bile duct repair in the present study can be attributed to the appropriate timing, meticulous technique and the tertiary care experience.

High-level quadriplegia is a devastating condition with limited treatment options. Bone marrow derived stem cells (BMSCs) are reported to have immunomodulatory and neurotrophic effects in spinal cord injury (SCI). We report a subject with complete C2 SCI who received 3 anatomically targeted intrathecal infusions of BMSCs under a single-patient expanded access IND. She underwent intensive physical therapy and was followed for over 2 years. At end-point, her AIS grade improved from A to B and she recovered focal pressure touch sensation over several body areas. We conducted serial neurophysiological testing to monitor changes in residual connectivity. Motor, sensory and autonomic system testing included MEPs, SSEPs, EMG recordings, F waves, galvanic skin responses and tilt-table responses. The quality and magnitude of voluntary EMG activations increased over time but remained below the threshold of clinically obvious movement. Unexpectedly, at 14 months post-injury deep inspiratory maneuvers triggered respiratory-like EMG bursting in the biceps and several other muscles. This finding means that connections between respiratory neurons and motor neurons were newly established, or unmasked. We also report serial analysis of MRI, ISNCSCI, pulmonary function, pain scores, CSF cytokines and bladder assessment. As a single case, the linkage of the clinical and neurophysiological changes to either natural history or to the BMSC infusions cannot be resolved. Nevertheless, such detailed neurophysiological assessment of high cervical SCI patients is rarely performed. Our findings indicate that electrophysiology studies are sensitive to define both residual connectivity and new plasticity.

Objective. To find out the incidence of involvement of individual arches, anatomical types of lesions, the age and sex incidence, the site and side of predilection, the common clinical features, the common investigations, treatment, and complications of the different anomalies. Setting. Academic Department of Otolaryngology, Head and Neck Surgery. Design. A 10 year retrospective study. Participants. 30 patients with clinically proven branchial anomalies including patients with bilateral disease totaling 34 lesions. Main Outcome Measures. The demographical data, clinical features, type of branchial anomalies, and the management details were recorded and analyzed. Results and Observations. The mean age of presentation was 18.67 years. Male to female sex ratio was 1.27 : 1 with a male preponderance. Of the 34 lesions, maximum incidence was of second arch anomalies (50%) followed by first arch. We had two cases each of third and fourth arch anomalies. Only 1 (3.3%) patients of the 30 presented with lesion at birth. The most common pathological type of lesions was fistula (58.82%) followed by cyst. 41.18% of the lesions occurred on the right side. All the patients underwent surgical excision. None of our patients had involvement of facial nerve in first branchial anomaly. All patients had tracts going superficial to the facial nerve. Conclusion. Confirming the extent of the tract is mandatory before any surgery as these lesions pass in relation to some of the most vital structures of the neck. Surgery should always be the treatment option. injection of dye, microscopic removal and inclusion of surrounding tissue while excising the tract leads to a decreased incidence of recurrence.

Narrow band imaging with magnification enables detailed assessment of duodenal villi and may be useful in predicting the presence of villous atrophy or normal villi. We aimed to assess the morphology of duodenal villi using magnification narrow band imaging and correlate it with histology findings in patients with clinically suspected malabsorption syndrome. Patients with clinical suspicion of malabsorption presenting at a tertiary care center were prospectively recruited in this diagnostic intervention study. Patients underwent upper gastrointestinal endoscopy using magnification narrow band imaging. The villous morphology in the second part of the duodenum was assessed independently by two endoscopists and the presence of normal or atrophic villi was recorded. Biopsy specimen was obtained from the same area and was examined by two pathologists together. The sensitivity and specificity of magnification narrow band imaging in detecting the presence of duodenal villous atrophy was calculated and compared to the histology. One hundred patients with clinically suspected malabsorption were included in this study. Sixteen patients had histologically confirmed villous atrophy. The sensitivity and specificity of narrow band imaging in predicting villous atrophy was 87.5% and 95.2%, respectively, for one endoscopist. The corresponding figures for the second endoscopist were 81.3% and 92.9%, respectively. The interobserver agreement was very good with a kappa value of 0.87. Magnification narrow band imaging performed very well in predicting duodenal villous morphology. This may help in carrying out targeted biopsies and avoiding unnecessary biopsies in patients with suspected malabsorption. © 2014 The Authors.

Three symptoms of (hypo)mania that clinically represent mood disorders mixed states have been omitted from the DSM-5 mixed features specifier because 'they fail to discriminate between manic and depressive syndromes'. Therefore, the present study examined the role of distractibility, irritability and psychomotor agitation (DIP) in characterising mixed depressive states. Fifty in-patients at a specialist mood disorders unit underwent a detailed longitudinal clinical evaluation (3-6 weeks) and were assessed on a range of standardized measures to characterise their illness according to depression subtype, duration of illness and clinical features-including specifically depressive and manic symptoms and the context in which these occur. 49 patients met criteria for major depressive episode, and of these, 34 experienced at least one dip symptom. Patients who endorsed distractibility were more likely to be diagnosed with Bipolar Disorder than Major Depressive Disorder; patients who endorsed irritable mood were more likely to have non-melancholic depression (admixture of depressive and anxiety symptoms), and patients who reported psychomotor agitation experienced a significantly greater number of distinct periods of (hypo)manic symptoms compared with those who did not. The present study used a modest sample size and did not control for medication or comorbid illness. Although this is inevitable when examining real-world patients in a naturalistic setting, future research needs to allow for comorbidity and its impact, specifically anxiety. The present findings suggest that all 3 symptoms that have been excluded from DSM-5 may be cardinal features of mixed states, as they 'dip' into depressive symptoms to create a mixed state.

Immediate breast reconstruction with skin graft is still little mentioned in the literature. Follow-up studies regarding the technique aspects are particularly scarce. The objective was to detail immediate breast reconstruction using autologous skin graft. Patients (n = 49) who underwent mastectomies and autologous immediate breast reconstruction with skin graft associated with a breast implant at A. C. Camargo Hospital (São Paulo, Brazil) between January 2007 and July 2010 were included. Information on clinical data, technique details and clinical outcome were prospectively collected. Following mastectomy, the autologous full-thickness skin graft was obtained through an inframammary fold incision along the contralateral breast in most patients. The skin graft was placed on the surface of the pectoralis major muscle after adjustments to conform to the mastectomy defect. A minimum of 10-month follow-up period was established. Patients' age ranged from 35 to 55 years and all received a silicone gel textured surface implant to obtain the necessary breast mound. The mean surgical time was 45 min, and the mean amount of skin resection was 4.5 cm in the largest diameter. Follow-up ranged from 10 to 35 months (median 23). All patients had silicone-gel textured surface implants to perform the breast mound reconstruction. No complications were observed in 87.8% of reconstructions. Forty-six patients (94%) had no complaints about the donor-site aesthetics. The result was a breast mound with a central ellipse of healed skin graft. Three (6%) poor results were observed. Thirty-six patients (67%) reported the results as good or very good. Our results lead us to conclude that autologous skin graft provided a reliable option in immediate breast reconstruction to skin-sparing mastectomy defects. The technique accomplished a single-stage implant breast reconstruction when there is inadequate skin coverage. Copyright © 2011 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

2005-06-01

Nine cases of failed biaxial wrist replacement underwent revision surgery and subsequent clinical and radiographic assessment at a mean follow-up of 28 months. Clinical assessment included the hospital for special surgery (HSS) and activities of daily living scoring systems. Five patients had a revision biaxial wrist replacement, three had wrist fusions and two underwent an excision arthroplasty. The mean HSS score was 73 for the revision biaxial replacements, 63 for the wrist fusions and 92 for the excision arthroplasties. The mean activities for daily living score was 16 for the revision biaxial replacements, 14 for the wrist fusion and 20 for the excision arthroplasties. Despite the experience of implant failure, six patients would still choose a primary wrist replacement again. All patients in this small series appear to have had good clinical outcomes. Revision to another wrist replacement appears no worse than a wrist fusion in the short term and patients value the preservation of movement that an implant offers.

Shin splints: MR appearance in a preliminary study.

To investigate the magnetic resonance (MR) imaging appearance of activity-related lower leg pain (shin splints syndrome) and evaluate the relative involvement of bone and soft tissues. Nineteen patients with activity-related lower leg pain and tenderness on palpation along the posteromedial tibia (shin splints) underwent clinical examination and MR imaging. Five also underwent plain radiography. MR findings were compared with patient demographics, clinical findings, and plain radiographs when available. Four MR patterns were identified: normal appearance (n = 7), periosteal fluid only (n = 5), abnormal marrow signal intensity (n = 5), and stress fracture (n = 2). Increased symptom duration correlated strongly with a normal MR image (P = .002). Plain radiographs appeared normal in all five patients for whom they were available. Patients with acute shin splints have a spectrum of MR findings, which suggests this clinical entity is part of a continuum of stress response in bone. The strong association between chronic symptoms and a normal-appearing MR image implies that this modality has less utility in these patients.

Benign duodenal and periampullary tumors are uncommon lesions requiring careful attention to their complex anatomic relationships with the major and minor papillae as well as the gastric outlet during surgical intervention. While endoscopy is less morbid than open resection, many lesions are not amenable to endoscopic removal. Robotic surgery offers technical advantages above traditional laparoscopy, and we demonstrate the safety and feasibility of this approach for a variety of duodenal lesions. We performed a retrospective review of all robotic duodenal resections between April 2010 and December 2013 from two institutions. Demographic, clinicopathologic, and operative details were recorded with special attention to the post-operative course. Twenty-six patients underwent robotic duodenal resection for a variety of diagnoses. The majority (88 %) were symptomatic at presentation. Nine patients underwent transduodenal ampullectomy, seven patients underwent duodenal resection, six patients underwent transduodenal resection of a mass, and four patients underwent segmental duodenal resection. Median operative time was 4 h with a median estimated blood loss of 50 cm(3) and no conversions to an open operation. The rate of major Clavien-Dindo grades 3-4 complications was 15 % at post-operative days 30 and 90 without mortality. Final pathology demonstrated a median tumor size of 2.9 cm with a final histologic diagnoses of adenoma (n = 13), neuroendocrine tumor (n = 6), gastrointestinal stromal tumor (GIST) (n = 2), lipoma (n = 2), Brunner's gland hamartoma (n = 1), leiomyoma (n = 1), and gangliocytic paraganglioma (n = 1). Robotic duodenal resection is safe and feasible for benign and premalignant duodenal tumors not amenable to endoscopic resection.

18 F-FDG PET/CT plays a significant role in the assessment of various infectious processes. Patients with suspected or known sites of infection are often referred for 18 F-FDG imaging while already receiving antibiotic treatment. The current study assessed whether antibiotic therapy affected the detectability rate of infectious processes by 18 F-FDG PET/CT. Methods: A 5-y retrospective study of all adult patients who underwent 18 F-FDG PET/CT in search of a focal source of infection was performed. The presence, duration, and appropriateness of antibiotic treatment before 18 F-FDG imaging were recorded. Diagnosis of an infectious process was based on microbiologic or pathologic data as well as on clinical and radiologic follow-up. Results: Two hundred seventeen patients underwent 243 PET/CT studies in search of a focal source of infection and were included in the study. Sixty-seven studies were excluded from further analysis because of a final noninfectious etiology or lack of further follow-up or details regarding the antibiotic treatment. The final study population included 176 18 F-FDG PET/CT studies in 153 patients (107 men, 46 women; age range, 18-86 y). One hundred nineteen studies (68%) were performed in patients receiving antibiotic therapy for a range of 1-73 d. A diagnosis of infection was made in 107 true-positive cases (61%), including 63 studies (59%) in patients receiving appropriate antibiotic therapy started before the performance of the 18 F-FDG PET/CT study. There were 52 true-negative (29%) and 17 false-positive (10%) 18 F-FDG PET/CT studies. No false-negative results were found. Conclusion: 18 F-FDG PET/CT correctly identified foci of increased uptake compatible with infection in most patients, including all patients receiving appropriate antimicrobial therapy, with no false-negative cases. On the basis of the current study results, the administration of antibiotics appears to have no clinically significant impact on the diagnostic accuracy of 18 F-FDG PET/CT performed for evaluation of known or suspected infectious processes. © 2017 by the Society of Nuclear Medicine and Molecular Imaging.

Injuries to the physis are common in children with a subset resulting in an osseous bar and potential growth disturbance. Magnetic resonance imaging allows for detailed assessment of the physis with the ability to generate 3-dimensional physeal models from volumetric data. The purpose of this study was to assess the interrater reliability of physeal bar area measurements generated using a validated semiautomated segmentation technique and to highlight the clinical utility of quantitative 3-dimensional (3D) physeal mapping in pediatric orthopaedic practice. The Radiology Information System/Picture Archiving Communication System (PACS) at our institution was searched to find consecutive patients who were imaged for the purpose of assessing a physeal bar or growth disturbance between December 2006 and October 2011. Physeal segmentation was retrospectively performed by 2 independent operators using semiautomated software to generate physeal maps and bar area measurements from 3-dimensional spoiled gradient recalled echo sequences. Inter-reliability was statistically analyzed. Subsequent surgical management for each patient was recorded from the patient notes and surgical records. We analyzed 24 patients (12M/12F) with a mean age of 11.4 years (range, 5-year to 15-year olds) and 25 physeal bars. Of the physeal bars: 9 (36%) were located in the distal tibia; 8 (32%) in the proximal tibia; 5 (20%) in the distal femur; 1 (4%) in the proximal femur; 1 (4%) in the proximal humerus; and 1 (4%) in the distal radius. The independent operator measurements of physeal bar area were highly correlated with a Pearson correlation coefficient (r) of 0.96 and an intraclass correlation coefficient for average measures of 0.99 (95% confidence interval, 0.97-0.99). Four patients underwent resection of the identified physeal bars, 9 patients were treated with epiphysiodesis, and 1 patient underwent bilateral tibial osteotomies. Semiautomated segmentation of the physis is a reproducible technique for generating physeal maps and accurately measuring physeal bars, providing quantitative and anatomic information that may inform surgical management and prognosis in patients with physeal injury.

The morbidity of bilateral lateral neck dissection (BLND) for thyroid cancers has not been described in detail. This study delineates the specific complications arising from BLND for thyroid cancers at a single high-volume center. To determine the morbidity associated with BLNDs for differentiated thyroid cancers at our institution. This was a retrospective review of medical records performed to identify patients having undergone BLNDs for thyroid cancers by a single surgeon at an academic, tertiary medical center in Toronto, Ontario, Canada, from 1988 to 2015. Patients who underwent BLND for papillary, follicular, or medullary thyroid cancers were identified through operative procedure codes and review of operative and pathology reports. The indication for this procedure was suspicious bilateral lateral compartment on imaging and clinical examination. Sixty-two patients who underwent BLND for thyroid cancers, with or without total thyroidectomy and central compartment dissection, were identified. The main outcome measures for this study were unanticipated medical or surgical complications during the operation or in the postoperative period. Secondary measures were oncologic outcomes, including regional structural or biochemical recurrence. Of the 62 patients, 24 were male (39%), and 38 (61%) were female. Their mean age was 46 years (range, 17-80 years). The overall risk of permanent hypoparathyroidism was 37%. There was 1 case of unanticipated permanent recurrent nerve paralysis and 1 case of temporary nerve paresis. Postoperative chyle fistula occurred in 6 cases (10%). There were 3 readmissions within 30 days of surgery, 1 pulmonary embolism, and 1 perioperative mortality. Fifty percent of patients had pN0 contralateral necks despite preoperative clinical suspicion. Four patients were found to have anaplastic thyroid cancers intraoperatively. Five patients (8%) developed nodal recurrence in the neck. Four patients died of their disease within available follow-up (mean, 3.2 years). Bilateral lateral neck dissection for thyroid cancers confers a significant amount of morbidity, including a significant rate of hypoparathyroidism. Knowledge of the complications of this procedure, especially in the setting of questionable survival benefit, may assist in preoperative decision-making and patient counseling.

Background The impact of personalized exercise training and a healthy dietary lifestyle in healthy volunteers on coronary flow reserve and cardiovascular function remains to be investigated in a controlled study setting. Purpose To examine the effects of a Mediterranean-inspired diet combined with regular physical exercise (standard) and a personalized supervised exercise program (DAPS) on coronary flow reserve and cardiovascular function. Results The number of males were 10 (59%) and 9 (47%) and mean age was 54 ± 12 and 55 ± 5 years in standard versus DAPS group, respectively. Primary outcomes were in addition to improved body composition and aerobic capacity, increased TDE-CFR (5.0%, CI:1.62,8.64, p = 0.005) and left ventricle ejection fraction (LVEF) during hyperemia (10.2%, CI:1.62,19.4, p = 0.022) in DAPS adjusted for the control period. Also, plasma fibrinogen decreased (−12.1%, CI:-22.0,–0.92, p = 0.035) in the DAPS group. Secondary outcomes, after adjusting DAPS intervention effects for the standard-training period, TDE-CFR and hyperemic LVEF remained significantly improved. Materials and Methods This randomized, controlled clinical trial (URL: http://www.clinicaltrials.gov NCT02713724) included 36 healthy volunteers who underwent exercise ECG before randomization to standard or DAPS groups. Standard-group was given gym-membership with limited instructions and general dietary advice. DAPS-group received personalized supervised exercise programs and more detailed dietary advice with regular contact with a personal trainer. Effects were evaluated after 3 months. All participants underwent coronary flow reserve by transthoracic ultrasound (TDE-CFR), blood marker analysis and examinations of vascular function. Standard-group was evaluated pre-control, post-control (=pre-intervention) and post-intervention. DAPS-group was examined at pre-intervention and post-intervention. Conclusions A personalized supervised training- and diet program improves cardiovascular status in healthy subjects with a physically inactive lifestyle and may be a promising approach for cardiovascular prevention in the general population.

OBJECTIVE The choice of graft material for duraplasty in decompressions of Chiari malformations remains a matter of debate. The authors present a detailed technique for harvesting ligamenta nuchae, as well as the clinical and radiographic outcomes of this technique, in a case series. METHODS The authors conducted a retrospective study evaluating the outcomes of Chiari malformation type I decompression and duraplasty in children aged 0-18 years at a single institution from 2013 to 2016. They collected both intraoperative and postoperative variables and compared them qualitatively to published data. RESULTS During the study period, the authors performed 25 Chiari malformation decompressions with ligamentum nuchae graft duraplasties. Of the 25 patients, 10 were females, and the mean age at surgery was 8.6 years (range 13 months to 18 years). The median operative time was 163 minutes (IQR 152-187 minutes), with approximately 10 minutes needed by a resident surgeon to harvest the graft. The mean length of stay was 3 nights (range 2-6 nights), and the mean follow-up was 12.6 months (range 0.5-43.5 months). One patient (4%) developed a CSF leak that was repaired using an oversewing patch. There were no postoperative pseudomeningoceles or infections. Of the 19 patients presenting with a syrinx, imaging showed improvement in 10 (53%) and 8 (42%) had stable syrinx size on imaging. Of 16 patients presenting with a symptomatic Chiari malformation, 14 (87.5%) experienced resolution of symptoms and in 1 (4%) symptoms remained the same. One patient (4%) presented with worsening syrinx and symptoms 1.5 months after initial surgery and underwent repeat decompression. CONCLUSIONS The authors describe a series of clinical and imaging outcomes of patients who underwent Chiari malformation decompression and duraplasty with a harvested ligamentum nuchae. The rates of postoperative CSF leak are similar to established techniques of autologous and artificial grafts, with similarly successful outcomes. Further study will be needed with larger patient cohorts to more directly compare duraplasty graft outcomes.

Detailed NORAD data have revealed updated orbital elements for the Ariane third-stage rocket body that underwent breakup on November 13, 1986, as well as for the Cosmos 1680 rocket body. Applying the maximum expected error due to the extrapolation of orbital elements to the date of the possible collision between the two bodies shows the smallest possible distance between bodies to have been 380 km, thereby precluding collision.

Hypocalcaemia is one of the most common complications after thyroidectomy; however, it is still unclear what preoperative factors could predict this event. The aim of this study was to evaluate the role of risk factors for hypocalcaemia after total thyroidectomy (TT). Consecutive patients who underwent total thyroidectomyat our institution between January 2014 and January 2016 were enrolled. The clinical and pathologic characteristics and surgical details of normocalcemic and hypocalcemic patients were compared. Univariate and multivariate analyses to estimate risk ratio were assessed. A total of 328 patients underwent TT; histology revealed benign and malignant disease in 83 and 17% of cases, respectively. Central-compartment neck dissection (CCND) was performed in 36 subjects (10.9%). Parathyroid glands were observed in 23% (76) of specimens. Laboratory asymptomatic hypocalcaemia was observed in 92 (28%) patients; symptomatic hypocalcaemia occurred in 26 (7.9%). Transient hypocalcaemia has been observed in 48 (14.6%) patients; permanent hypocalcaemia occurred in two subjects (0.6%). On univariate analysis, malignant pathology (p < 0.001), CCND (p < 0.05), female gender (p < 0.001), presence of at least two parathyroid glands in specimens (p < 0.002), and operative time longer than 120 min (p < 0.05) were factors that significantly increased the risk of developing asymptomatic and transient hypocalcaemia. After logistic regression analysis, malignant pathology (p < 0.000; p < 0.001) and CCND (p < 0.005; p = 0.013) were the significant factors that affected the development of symptomatic and transient hypocalcaemia. The presence of malignant pathology and CCND was found to be significant risks factors for postoperative hypocalcaemia. In patients in whom this pathological features are present, attention should be paid to rapidly start an adequate therapy.

Ruptured arteriovenous malformations (AVMs) are a frequent cause of intracerebral hemorrhage (ICH). In some cases, compression from the associated hematoma in the acute setting can partially or completely occlude an AVM, making it invisible on conventional angiography techniques. The authors report on the successful use of cone-beam CT angiography (CBCT-A) to precisely identify the underlying angioarchitecture of ruptured AVMs that are not visible on conventional angiography. Three patients presented with ICH for which they underwent examination with CBCT-A in addition to digital subtraction angiography and other imaging modalities, including MR angiography and CT angiography. All patients underwent surgical evacuation due to mass effect from the hematoma. Clinical history, imaging studies, and surgical records were reviewed. Hematoma volumes were calculated. In all 3 cases, CBCT-A demonstrated detailed anatomy of an AVM where no lesion or just a suggestion of a draining vein had been seen with other imaging modalities. Magnetic resonance imaging demonstrated enhancement in 1 patient; CT angiography demonstrated a draining vein in 1 patient; 2D digital subtraction angiography and 3D rotational angiography demonstrated a suggestion of a draining vein in 2 cases and no finding in the third. In the 2 patients in whom CBCT-A was performed prior to surgery, the demonstrated AVM was successfully resected without evidence of a residual lesion. In the third patient, CBCT-A allowed precise targeting of the AVM nidus using Gamma Knife radiosurgery. Cone-beam CT angiography should be considered in the evaluation and subsequent treatment of ICH due to ruptured AVMs. In cases in which the associated hematoma compresses the AVM nidus, CBCT-A can have higher sensitivity and anatomical accuracy than traditional angiographic modalities, including digital subtraction angiography.

Diagnostic accuracy of mpMRI (multiparametric magnetic resonance imaging) in the diagnosis of clinically significant prostate cancer (csPCa) has been evaluated and compared with transperineal saturation prostate biopsy (SPBx). From January 2011 to Febraury 2018 1032 men (median age 63 years) with median PSA of 8.6 ng/ml underwent repeat SPBx (reference test) for the suspicion of cancer. All the patients underwent 3.0 Tesla pelvic mpMRI before SPBx and the lesions with PI-RADS (Prostate Imaging-Reporting and Data System) score ≥ 3 were submitted to additional targeted fusion prostate biopsy (TPBx). A T1c PCa was found in 372/1032 (36%) patients and 272 (73.1%) of them were classified as csPCa. SPBx vs. TPBx PI-RADS > 3 vs. TPBx PI-RADS > 4 diagnosed 95.6 vs. 83.8 vs. 60.3% (p < 0.0001) of the csPCa; in detail, SPBx missed 12/272 (4.5%) csPCa vs. 44/272 (16.2%) and 108/272 (39.7%) missed by TPBx PI-RADS > 3 and TPBx PI-RADS > 4 (p < 0.0001), respectively. The use of mpMRI as "a triage test" would have spared 49.3% vs. 73.6% using as cut-off a PI-RADS > 3 vs PI-RADS > 4, respectively. MpMRI could significantly reduce the number of unnecessary repeat prostate biopsies (about 50% of the cases using a PI-RADS score > 3); at the same time, the patients should be informed of the false-negative rate for csPCa of TPBx for PI-RADS > 3 (16.2%) or > 4 (39.7%).

OBJECTIVE To describe the technique and short- and long-term outcomes for dogs undergoing double-pigtail ureteral stent placement for treatment of benign ureteral obstruction. DESIGN Retrospective case series. ANIMALS 44 dogs (57 ureters). PROCEDURES Medical records of dogs that underwent ureteral stenting for treatment of benign ureteral obstruction between 2010 and 2013 were reviewed. Signal-ment, history, pertinent diagnostic imaging results, endourologic and post-procedural details, duration of hospitalization, complications, and outcome (short term, 7 to 30 days; long term, > 30 days) were recorded. Ureteral stent placement was performed endoscopically, surgically, or both, with fluoroscopic guidance. RESULTS 57 ureters (44 dogs) underwent stenting because of obstructive ureterolithiasis (n = 48 [84%]), stricture (5 [9%]), or both (4 [7%]). Endoscopic or surgical techniques were successful for stent placement in 45 of 55 and 12 of 12 ureters (34/42 and 10/10 dogs), respectively. Median hospitalization time was 1 day. Median creatinine concentration was 2 mg/dL prior to stenting and 1.3 mg/dL 3 months after the procedure. Urinary tract infections were present in 26 of 44 (59%) dogs prior to stenting and in 11 of 43 dogs (26%) after stenting. One of the 44 (2%) dogs died after undergoing stenting, but the cause of death was not related to the procedure. Median follow-up time was 1,158 days (range, 3 to > 1,555 days), with 30 of 44 dogs alive at the time of last follow-up. CONCLUSIONS AND CLINICAL RELEVANCE Results suggested that ureteral stenting may be a viable option for first-line treatment of dogs with benign ureteral obstruction. However, patients should be monitored for urinary tract infection following stenting.

With the increasing prevalence of coronary artery disease, percutaneous coronary artery procedures have become even more important. Our study has compared transradial to transfemoral artery approach for coronary procedures in Indian population. Comparison of transradial and transfemoral artery approach for percutaneous coronary procedures. 26,238 patients, who underwent percutaneous coronary artery procedures, were divided into two groups depending upon transradial and transfemoral artery approach and compared for the various demographic and clinical characteristics, risk factors profile, vascular access and procedural details. 26,238 patients underwent percutaneous coronary procedures at our center. 81% were male and 19% were female. 55.65% and 44.35% procedures were done through transfemoral and transradial approach, respectively. 17,417 (66.38%) coronary angiographies were done, out of which 53.92% were transradial and 46.08% were transfemoral procedures. 8821 (33.62%) Percutaneous Transluminal Coronary Angioplasty (PTCA) were done, out of which 25.46% and 74.54% were done through transradial and transfemoral approach, respectively. Mean fluoroscopy time was 4.40 ± 3.55 min for transradial and 3.30 ± 3.66 min for transfemoral CAG (p < 0.001). For PTCA mean fluoroscopy time was 13.53 ± 2.53 min for transradial and 12.61 ± 9.524 min for transfemoral PTCA (p < 0.001). Minor and major procedure related complications and total duration of hospital stay were lower in transradial as compared to transfemoral group. The number of percutaneous transradial procedures have increased significantly with reduced complication rates and comparable success rate to transfemoral approach, along with the additional benefits to patient in terms of patient comfort, preference and reduced cost of health delivery.

To describe a new technique for transcatheter patent ductus arteriosus (PDA) closure in extremely preterm infants using commercially available technology. PDA in premature neonates continues to be a significant clinical problem contributing importantly to both morbidity and mortality. Surgical ligation and medical therapy both have their drawbacks. Hospital records and catheterization reports of all premature neonates (< 32 weeks gestation) who underwent transcatheter PDA closure between March 2013 and February 2014 were reviewed. Particular attention was paid to procedural details, complications, and short and mid-term outcomes. Six premature infants born at gestational ages ranging between 26 and 31 weeks (median, 26 weeks) underwent attempted transcatheter PDA closure using the Amplatzer Vascular Plug II (AVP II). Median age and weight was 21.5 days (16-80 days) and 1,180 g (870-2,240 g), respectively. Fluoroscopy and echocardiography were used to guide device. Contrast angiography was not used in any patient. Complete closure was achieved in all patients with no major procedural complications. Median fluoroscopy and procedural times were 9.4 (0-19.5) and 51.5 (33-87) min, respectively. All patients were alive at the time of this report. There were no instances of device migration, left pulmonary artery (LPA), or aortic coarctation. This preliminary study demonstrates that transcatheter PDA closure can be successfully performed in extremely preterm neonates using currently available technology with a high success rate and a low incidence of complications. This report also describes a novel transvenous approach using a combination of echocardiography and judicious use of fluoroscopy to avoid arterial access in this fragile patient population. © 2014 Wiley Periodicals, Inc. © 2014 Wiley Periodicals, Inc.

Clinico-pathological patterns of a rare presentation of abdominal neuroblastoma in children.

To study the diagnosis, management, and outcome of abdominal neuroblastoma (NBL) in infants and children and also the behavior of some rare types. This is a retrospective review of 46 infants and children having abdominal NBL at King Abdulaziz University Hospital, Jeddah, Kingdom of Saudi Arabia and Tanta University Hospital, Tanta, Egypt (a joint study) between February 2008 and January 2012. The patients' medical records were reviewed for demographic details, clinical presentations, histopathology, radiological diagnosis, management, and outcome. Of the 46 patients, 5 (10.7%), three males and two females, aged 1.5-6.5 years (mean: 4.5 years) had rare types of NBL (one bilateral NBL, one pelvic NBL, one pelvic-abdominal, and there were two cases of ganglioneuroblastoma). Three patients (two ganglioneuroblastoma and one pelvic) underwent complete surgical removal of the tumor with a good disease survival, whereas the other two patients (two bilateral and one pelviabdominal) had advanced disease and received palliative chemoradiotherapy. The remaining 41 patients, 23 males (56.1%) and 18 females (43.9%), with mean age 3.9 years (range: 1-7 years), had unilateral abdominal NBL. Twelve of them had resectable tumor and underwent primary surgical removal of the tumor, whereas the remaining 29 patients had unresectable tumor and received pre-operative chemotherapy with good response of the tumor in seven patients and no response in the remaining 22 patients. Primary complete surgical removal of tumor is advisable in localized NBL with a good outcome, whereas in advanced cases, it is better to start with pre-operative chemotherapy to downsize the tumour mass and safe delayed surgical excision. An increase in patient's age is associated with advanced stage of NBL and poor prognosis except in ganglioneuroblastoma cases due to maturation of tumor cells.

Since its widespread acceptance for the treatment of early gastric cancer, laparoscopic gastrectomy has been gaining popularity as a treatment option for advanced gastric cancer. However, laparoscopic total gastrectomy (LTG) with splenectomy is seldom performed, because of its difficulty of removal of station 10 lymph nodes; splenectomy is technically essential for complete removal of these lymph nodes. The purpose of this study was to describe the details of the LTG procedure and to evaluate the short- and long-term outcomes of LTG with splenectomy. Of 725 consecutive patients with gastric cancer who underwent laparoscopic gastrectomy with lymph node dissection in our institution from January 1996 to December 2012, 18 consecutive patients who underwent LTG with splenectomy were enrolled in this study. No operative mortality occurred, and the pathological margins were free from cancer cells in all patients. The mean operation time was 388 min (range 324-566 min). The mean volume of blood loss was 45 ml (range 5-347 ml), and the mean number of dissected lymph nodes was 51 (range 40-105). Postoperative morbidity occurred in six patients (33.3%) (each with grade B postoperative pancreatic fistula, postoperative bleeding, chylous ascites, atelectasis, ileus, and intra-abdominal infection). Five patients (27.8%) developed recurrence (four in the peritoneum and one in the liver), and the overall 3- and 5-year survival rates were 83.0 and 72.6%, respectively. Considering the 0% mortality rate and low rates of postoperative morbidity and locoregional recurrence, LTG with splenectomy is technically and oncologically acceptable. This procedure can be expanded to include advanced gastric cancer, which generally requires splenectomy for lymph node dissection.

The national observational study of diagnostic and interventional cardiac catheterization (ONACI) is a prospective multicenter registry of the French Society of Cardiology including all interventional cardiology procedures performed from 2004. We aimed to evaluate "real-world" management of patients with coronary artery disease in France from this registry. The present study was focused on data collected from 2004 to 2008. Patient demographics and co-morbidities, invasive parameters, treatment options, and procedural techniques were prospectively collected. Patients were recruited from 99 hospitals (55% of patients were hospitalized in private clinics and 45% in public institutions). During a 5-year period, a total of 298,105 patients underwent coronary angiography and 176,166 patients underwent percutaneous coronary intervention. Diagnosis was acute coronary syndrome in 22%, stable angina or silent ischemia in 23%, and atypical chest pain in 9% of cases. Normal coronary arteries or nonsignificant coronary narrowing were found in 26% of patients. Radial access was increasingly used over the years regardless of the indication. The average number of percutaneous coronary interventions per procedure was 1.5 ± 0.7 (range, 1.3 ± 0.7 to 1.5 ± 0.7) and that of stents per procedure was 1.5 ± 0.8 (range, 1.5 ± 0.8 to 1.6 ± 0.8). Drug-eluting stents were used in 45% (range, 34% to 62%), increasing from 2004 to 2006, and then decreasing after the 2006 controversy. In conclusion, ONACI is one of the largest catheterization registries during this period, providing a detailed and comprehensive global description of the spectrum and management of patients with suspected coronary artery disease undergoing cardiac catheterization.

To determine the signalment, tibial plateau leveling osteotomy (TPLO) plate type, clinical staging information, treatment, and oncological outcome in dogs that developed osteosarcoma at the proximal aspect of the tibia following TPLO and to calculate the interval between TPLO and osteosarcoma diagnosis. Multi-institutional retrospective case series. 29 dogs. Medical records from 8 participating institutions were searched for dogs that developed osteosarcoma (confirmed through cytologic or histologic evaluation) at previous TPLO sites. Signalment, TPLO details, staging tests, treatment data, and outcome information were recorded. Descriptive statistics were calculated, and disease-free intervals and survival times were evaluated by means of Kaplan-Meier analysis. 29 dogs met the inclusion criteria. The mean age was 9.2 years and mean weight was 45.1 kg (99.2 lb) at the time of osteosarcoma diagnosis. Most dogs had swelling over the proximal aspect of the tibia (17/21) and lameness of the affected limb (28/29). The mean interval between TPLO and osteosarcoma diagnosis was 5.3 years. One type of cast stainless steel TPLO plate was used in most (18) dogs; the remaining dogs had received plates of wrought stainless steel (n = 4) or unrecorded type (7). Twenty-three of 29 dogs underwent treatment for osteosarcoma. Median survival time for 10 dogs that underwent amputation of the affected limb and received ≥ 1 chemotherapeutic treatment was 313 days. Results supported that osteosarcoma should be a differential diagnosis for dogs with a history of TPLO that later develop lameness and swelling at the previous surgical site. Oncological outcome following amputation and chemotherapy appeared to be similar to outcomes previously reported for dogs with appendicular osteosarcoma.

Previous studies have demonstrated that early surgery in Crohn disease (CD) can result in a better clinical course than late surgery. The aim of this study was to compare the clinical course of CD following bowel resection performed at the time of diagnosis (early surgery) and during the course of the disease (late surgery).We reviewed medical records from a hospital-based cohort database that includes Korean CD patients diagnosed before 2009. Patients who underwent bowel resection were included. Age, sex, disease phenotype, time of surgery, medication history including use of corticosteroids, immunomodulators, and biologics, and further surgical history were assessed.In all, 243 CD patients who had undergone bowel resection were included, and 120 patients underwent surgery at the time of diagnosis, while 123 underwent surgery after diagnosis (median 105 months, range 2-277). The use of biologics was significantly higher in the late surgery group than in the early surgery group (P = .020). The use of immunomodulators and reoperation rates did not differ between the groups. Early surgery was associated with less use of biologics (Kaplan-Meier curve analysis P = .015). Multivariate analysis indicated that early surgery and old age at surgery were independent variables associated with less use of biologics.CD patients who underwent bowel resection at the time of diagnosis have a more favorable disease course, represented by less use of biologics. Early surgery might be a treatment option in a subset of CD patients.

Introduction Curettage of the cyst and bone grafting are the most common methods used in the treatment of unicameral bone cysts (UBC) and aneurysmal bone cysts (ABC). Recurrence of these cysts is often associated with insufficient curettage of the cyst during surgery. In this study, we aimed to evaluate the effect of insufficient curettage on recurrence in patients with UBC and ABC. Methods The retrospective study included 18 patients with UBC and 14 patients with ABC that were surgically treated by curettage and bone grafting in our clinic between 2006-2013. Mean age was 19.80 (range, 4-50) years in the patients with UBC and 21.76 (range, 4-56) in the patients with ABC. The diagnosis of the cysts was established both clinically and radiologically. Mean follow-up period was 36 (range, 6-60) months both in the patients with UBC and ABC. The patients with recurrence underwent a second curettage and grafting procedure. Healing and recurrence were evaluated according to modified Neer's scale. Results Recurrence occurred in 8 patients. Of these, 5 patients underwent a second curettage and grafting procedure and 3 patients were lost to follow-up. Complete healing occurred in all the patients that underwent a second curettage and grafting procedure. Conclusion The achievement of complete healing in the patients that underwent a second curettage and grafting procedure indicates that the recurrence of UBC and ABC is associated with insufficient curettage.

To present diverse symptoms, signs, and findings on diagnostic tests of 11 patients with superior semicircular canal dehiscence (SSCD) syndrome and surgical treatments for dehiscence of 3 patients. Retrospective case review. Tertiary neurotologic and audiologic center. Patients with SSCD documented by history, physical examination, vestibular function testing, and high-resolution computed tomographic scans. Two patients underwent surgical procedures through middle fossa approach, and 1 patient underwent transmastoid repair. The rest underwent conservative treatments. Eleven patients were identified as SSCD. The variety of clinical manifestations, including 1) hearing presentations: mix hearing loss (4 of 11), conductive hearing loss (3 of 11), profound sensorineural hearing loss (2 of 11), and normal hearing (2 of 11); 2) vestibular manifestations: chronic disequilibrium (8 of 11), Tullio phenomenon (7 of 11), Hennebert sign (8 of 11), tinnitus (3 of 11), and autophony (3 of 11); and 3) accompanying disorders: encephalomeningocele (1 of 11). Abnormal nystagmus was identified in 3 patients. Dehiscence of bone overlying superior semicircular canal was confirmed by high-resolution computed tomographic scan in all cases. Three patients underwent operative management. (2 through the middle fossa approach and 1 through a transmastoid repair). Superior semicircular canal dehiscence demonstrates diverse and complex clinical features. Tegmental or petrosal bone rarefaction or mild dehiscences can be a harbinger or an aggressive cause of developing SSCD. No correlation was observed between the size of dehiscence and the severity of vestibular symptoms or the degree of hearing loss. Surgical repair of dehiscence can relieve symptoms with low morbidity.

To evaluate the effectiveness of transcatheter arterial embolization (TAE) for gastrointestinal (GI) bleeding caused by GI lymphoma. The medical records of 11 patients who underwent TAE for GI bleeding caused by GI lymphoma between 2001 and 2015 were reviewed retrospectively. A total of 20 TAE procedures were performed. On angiography, contrast extravasation, and both contrast extravasation and tumor staining were seen in 95 % (19/20) and 5 % (1/20) of the procedures, respectively. The most frequently embolized arteries were jejunal (n = 13) and ileal (n = 5) branches. Technical and clinical success rates were 100 % (20/20) and 27 % (3/11), respectively. The causes of clinical failure in eight patients were rebleeding at new sites. In four patients who underwent repeat angiography, the bleeding focus was new each time. Three patients underwent small bowel resection due to rebleeding after one (n = 2) or four (n = 1) times of TAEs. Another two patients underwent small bowel resection due to small bowel ischemia/perforation after three or four times of TAEs. The 30-day mortality rate was 18 % due to hypovolemic shock (n = 1) and multiorgan failure (n = 1). Angiogram with TAE shows limited therapeutic efficacy to manage GI lymphoma-related bleeding due to high rebleeding at new sites. Although TAE can be an initial hemostatic measure, surgery should be considered for rebleeding due to possible bowel ischemic complication after repeated TAE procedures.

To describe infectious and non-infectious ocular complications found in patients with lung transplants. 545 patients underwent lung transplantation from January 1998 to September 2008 at the Cleveland Clinic. Patients who underwent ophthalmic examination at the Cole Eye Institute after lung transplantation were included in the study. Diagnoses, treatments, surgeries, laboratory parameters of immune status and patient survival were examined. Of the 545 patients who received a lung transplant during the study period at the Cleveland Clinic, 46 (8.4%) patients underwent ophthalmology examination after a lung transplant. The most common ocular finding was posterior subcapsular cataract, found in 13/46 (28.3%) patients. Infectious ocular complications were present in 6/46 patients (13.0%) including fungal infections (rhino-orbital mucormycosis (n=1), disseminated Pseudallescheria boydii infection (n=2)), cytomegalovirus retinitis (n=1), varicella-zoster virus keratouveitis (n=1) and herpes zoster ophthalmicus (n=1). Five of six patients with infectious ocular complications died within 6 months of evaluation. Decreased absolute lymphocyte count was associated with infectious ocular complications (p=0.014). Many ocular conditions can occur in patients with lung transplants. Ocular infectious complications were uncommon but may be associated with increased mortality.

Treating thoracic infective spondylodiscitis with anterior surgical approaches carry a relatively high risk of perioperative and postoperative complications. Posterior approaches have been reported to result in lower complication rates than anterior procedures, but more evidence is needed to demonstrate the safety and efficacy of 1-stage posterior approaches for treating infectious thoracic spondylodiscitis.Preoperative and postoperative clinical data, of 18 patients who underwent 2 types of 1-stage posterior procedures, costotransversectomy and transforaminal thoracic interbody debridement and fusion and 7 patients who underwent anterior debridement and reconstruction with posterior instrumentation, were retrospectively assessed.The clinical outcomes of patients treated with 1-stage posterior approaches were generally good, with good infection control, back pain relief, kyphotic angle correction, and either partial or solid union for fusion status. Furthermore, they achieved shorter surgical time, fewer postoperative complications, and shorter hospital stay than the patients underwent anterior debridement with posterior instrumentation.The results suggested that treating thoracic spondylodiscitis with a single-stage posterior approach might prevent postoperative complications and avoid respiratory problems associated with anterior approaches. Single-stage posterior approaches would be recommended for thoracic spine infection, especially for patients with medical comorbidities.

Female vaginoplasty reconstruction, by choice, is usually performed with adjacent tissue. However in some clinical conditions such as high urogenital confluence sinus, cloacal malformation with extreme vaginal hypoplasia, local tissue may not be available. When vaginal replacement is performed in pediatric patients intestinal segments is preferred to non-operative procedures that require continuative dilations. However mucus production, malignant transformation risk and diversion colitis are important side effects. We present a nouvel technique for vaginoplasty in a female child presenting with an isolated urogenital sinus malformation without virilization. The patient at 20 months underwent vaginoplasty using tubularized bladder mucosal graft. Surgical procedure was devoid of complications. Pubertal development occurred at age of 15. She underwent regular follow up until 18 years of age. At this age we performed clinical evaluation: absence of vaginal introitus stenosis and good cosmetic results were observed. Then she underwent vaginoscopy with multiple biopsies. Pathology examination of the bladder mucosal graft evidenced a normal structure of the mucosa, with a stratified squamous epithelium. Different techniques are taken into account for vaginal reconstruction according to the severity and to the type of malformation. We describe the use of bladder mucosal graft with favorable results after long term follow-up. Copyright © 2018. Published by Elsevier Inc.

Objective The aim of this study was to evaluate the usefulness of ultrasonography in the diagnosis of hemorrhagic cystitis following bone marrow transplantation in children. Material and methods The study involved an analysis of clinical material and the results of imaging tests performed in 334 patients who underwent hematopoietic cell transplantation. Ultrasonographic findings in 42 patients with hemorrhagic cystitis were analyzed in detail. The ultrasound images served to assess the severity of hemorrhagic cystitis and the results were compared with the clinical assessment of the disease on the Droller scale, as well as the laboratory and endoscopic tests. Results In the studied group of patients hemorrhagic cystitis following allogeneic transplantation was diagnosed in 12.5% cases. 73.8% patients received transplants from unrelated donors, 26.2% – from compatible siblings. The study revealed a higher incidence of hemorrhagic cystitis in children above 10 years of age. Grade 3 according to the Droller was diagnosed in 42.9%, grade 2 – in 30.9%, grade 4 – in 14.3%, and grade 1 – in 11.9% patients. The number of ultrasound examinations depended on the clinical symptoms, severity, duration and co-occurrence of other complications following the transplantation and was within the 1–15 range (average: 4.6). Grades 3 and 4 were related to the poor clinical condition of the patients and to their longer hospitalization. During this period there was an increased risk of renal malfunction and acute renal failure, post-inflammatory narrowing of the ureters, hydronephrosis, and in grade 4 the fibrosis of the bladder with reduced bladder capacity. Analyses demonstrated a significant correlation between the ultrasound image of the bladder wall and the clinical severity. Conclusions Ultrasound with Doppler options remains the primary diagnostic tool in the evaluation of hemorrhagic cystitis, and is useful in terms of its diagnosis, determination of the severity, and monitoring of the treatment.

Till date, mutations in the genes PAX3 and MITF have been described in Waardenburg syndrome (WS), which is clinically characterised by congenital hearing loss and pigmentation anomalies. Our study intended to determine the frequency of mutations and deletions in these genes, to assess the clinical phenotype in detail and to identify rational priorities for molecular genetic diagnostics procedures. Prospective analysis. 19 Caucasian patients with typical features of WS underwent stepwise investigation of PAX3 and MITF. When point mutations and small insertions/deletions were excluded by direct sequencing, copy number analysis by multiplex ligation-dependent probe amplification was performed to detect larger deletions and duplications. Clinical data and photographs were collected to facilitate genotype-phenotype analyses. All analyses were performed in a large German laboratory specialised in genetic diagnostics. 15 novel and 4 previously published heterozygous mutations in PAX3 and MITF were identified. Of these, six were large deletions or duplications that were only detectable by copy number analysis. All patients with PAX3 mutations had typical phenotype of WS with dystopia canthorum (WS1), whereas patients with MITF gene mutations presented without dystopia canthorum (WS2). In addition, one patient with bilateral hearing loss and blue eyes with iris stroma dysplasia had a de novo missense mutation (p.Arg217Ile) in MITF. MITF 3-bp deletions at amino acid position 217 have previously been described in patients with Tietz syndrome (TS), a clinical entity with hearing loss and generalised hypopigmentation. On the basis of these findings, we conclude that sequencing and copy number analysis of both PAX3 and MITF have to be recommended in the routine molecular diagnostic setting for patients, WS1 and WS2. Furthermore, our genotype-phenotype analyses indicate that WS2 and TS correspond to a clinical spectrum that is influenced by MITF mutation type and position.

Cardiovascular Magnetic Resonance (CMR) provides valuable information in patients with hypertrophic cardiomyopathy (HCM) based on myocardial tissue differentiation and the detection of small morphological details. CMR at 7.0T improves spatial resolution versus today's clinical protocols. This capability is as yet untapped in HCM patients. We aimed to examine the feasibility of CMR at 7.0T in HCM patients and to demonstrate its capability for the visualization of subtle morphological details. We screened 131 patients with HCM. 13 patients (9 males, 56 ±31 years) and 13 healthy age- and gender-matched subjects (9 males, 55 ±31years) underwent CMR at 7.0T and 3.0T (Siemens, Erlangen, Germany). For the assessment of cardiac function and morphology, 2D CINE imaging was performed (voxel size at 7.0T: (1.4x1.4x2.5) mm3 and (1.4x1.4x4.0) mm3; at 3.0T: (1.8x1.8x6.0) mm3). Late gadolinium enhancement (LGE) was performed at 3.0T for detection of fibrosis. All scans were successful and evaluable. At 3.0T, quantification of the left ventricle (LV) showed similar results in short axis view vs. the biplane approach (LVEDV, LVESV, LVMASS, LVEF) (p = 0.286; p = 0.534; p = 0.155; p = 0.131). The LV-parameters obtained at 7.0T where in accordance with the 3.0T data (pLVEDV = 0.110; pLVESV = 0.091; pLVMASS = 0.131; pLVEF = 0.182). LGE was detectable in 12/13 (92%) of the HCM patients. High spatial resolution CINE imaging at 7.0T revealed hyperintense regions, identifying myocardial crypts in 7/13 (54%) of the HCM patients. All crypts were located in the LGE-positive regions. The crypts were not detectable at 3.0T using a clinical protocol. CMR at 7.0T is feasible in patients with HCM. High spatial resolution gradient echo 2D CINE imaging at 7.0T allowed the detection of subtle morphological details in regions of extended hypertrophy and LGE.

To elucidate the usefulness of next generation sequencing for diagnosis of inherited myopathy, and to analyze the relevance between clinical phenotype and genotype in inherited myopathy. Related genes were selected for SureSelect target enrichment system kit (Panel Version 1 and Panel Version 2). A total of 134 patients who were diagnosed as inherited myopathy clinically underwent next generation sequencing in Department of Pediatrics, Peking University First Hospital from January 2013 to June 2014. Clinical information and gene detection result of the patients were collected and analyzed. Seventy-seven of 134 patients (89 males and 45 females, visiting ages from 6-month-old to 26-year-old, average visiting age was 6 years and 1 month) underwent next generation sequencing by Panel Version 1 in 2013, and 57 patients underwent next generation sequencing by Panel Version 2 in 2014. The gene detection revealed that 74 patients had pathogenic gene mutations, and the positive rate of genetic diagnosis was 55.22%. One patient was diagnosed as metabolic myopathy. Five patients were diagnosed as congenital myopathy; 68 were diagnosed as muscular dystrophy, including 22 with congenital muscular dystrophy 1A (MDC1A), 11 with Ullrich congenital muscular dystrophy (UCMD), 6 with Bethlem myopathy (BM), 12 with Duchenne muscular dystrophy (DMD) caused by point mutations in DMD gene, 5 with LMNA-related congenital muscular dystrophy (L-CMD), 1 with Emery-Dreifuss muscular dystrophy (EDMD), 7 with alpha-dystroglycanopathy (α-DG) patients, and 4 with limb-girdle muscular dystrophy (LGMD) patients. Next generation sequencing plays an important role in diagnosis of inherited myopathy. Clinical and biological information analysis was essential for screening pathogenic gene of inherited myopathy.

Nelson's syndrome refers to aggressive pituitary corticotroph adenoma growth after bilateral adrenalectomy for treatment of Cushing's disease (CD). Pasireotide, a novel somatostatin analog, has been effective in treating CD. Here, the first case report of a patient with Nelson's syndrome treated with pasireotide is presented. A 55-year-old female was diagnosed with CD in 1973 at age 15 years and underwent bilateral adrenalectomy 1 year later. She subsequently developed Nelson's syndrome and underwent multiple surgeries and radiotherapy for adenoma growth. After presentation with ocular pain, third cranial nerve palsy, and a finding of suprasellar tumor enlargement with hemorrhage, she began pasireotide long-acting release 60 mg/28 days im. At baseline, fasting plasma ACTH was 42 710 pg/mL (normal, 5-27 pg/mL), and fasting plasma glucose was 98 mg/dL. After 1 month, ACTH declined to 4272 pg/mL, and it has remained stable over 19 months of follow-up. Hyperpigmentation progressively improved. Magnetic resonance imaging scans show reduction in the suprasellar component. Fasting plasma glucose increased to 124 mg/dL, and the patient underwent diabetes management. In this clinical case seminar, the current understanding of the treatment of Nelson's syndrome and the use of pasireotide in CD are summarized. A case of Nelson's syndrome with clinically significant and dramatic biochemical and clinical responses to pasireotide administration is reported. Hyperglycemia was noted after pasireotide administration. Pasireotide may represent a useful tool in the medical management of Nelson's syndrome. Further study of the potential benefits and risks of pasireotide in this population is necessary.

Breast conserving surgery (BCS) has been the standard surgical procedure for the treatment of early breast cancer. Endoscopic subcutaneous mastectomy (ESM) plus immediate reconstruction with implants is an emerging procedure. The objective of this prospective study was to evaluate the clinical outcomes of these two surgical procedures in our clinical setting. From March 2004 to October 2007, 43 patients with breast cancer underwent ESM plus axillary lymph node dissection and immediate reconstruction with implants, while 54 patients underwent BCS. The clinical and pathological characteristics, surgical safety, and therapeutic effects were compared between the two groups. There were no significant differences in the age, clinical stage, histopathologic type of tumor, operative blood loss, postoperative drainage time, and postoperative complications between the two groups (P > 0.05). The postoperative complications were partial necrosis of the nipple and superficial skin flap in the ESM patients, and hydrops in the axilla and residual cavity in the BCS patients. There was no significant difference in the rate of satisfactory postoperative cosmetic outcomes between the ESM (88.4%, 38/43) and BCS (92.6%, 50/54) patients (P > 0.05). During follow-up of 6 months to 4 years, all patients treated with ESM were disease-free, but 3 patients who underwent BCS had metastasis or recurrence -one of these patients died of multiple organ metastasis. After considering the wide indications for use, high surgical safety, and favorable cosmetic outcomes, we conclude that ESM plus axillary lymph node dissection and immediate reconstruction with implants - the new surgery of choice for breast cancer - warrants serious consideration as the prospective next standard surgical procedure.

Tumor associated macrophages (TAM) in malignant tumors have been linked to tumor aggressiveness and represent a new target for cancer immunotherapy. As new TAM-targeted immunotherapies are entering clinical trials, it is important to detect and quantify TAM with non-invasive imaging techniques. The purpose of this study was to determine if ferumoxytol-enhanced MRI can detect TAM in lymphomas and bone sarcomas of pediatric patients and young adults. In a first-in-patient , IRB-approved prospective clinical trial, 25 pediatric and young adult patients with lymphoma or bone sarcoma underwent ferumoxytol-enhanced MRI. To confirm ferumoxytol enhancement, five pilot patients (2 lymphoma, 3 bone sarcoma) underwent pre- and post-contrast MRI. Subsequently, 20 patients (10 lymphoma, 10 bone sarcoma) underwent ferumoxytol-enhanced MRI 24-48 hours after intravenous injection, followed by tumor biopsy/resection and macrophage staining. To determine if ferumoxytol-MRI can differentiate tumors with different TAM content, we compared T2* relaxation times of lymphomas and bone sarcomas. Tumor T2* values of 20 patients were correlated with CD68+ and CD163+ TAM quantities on histopathology. Significant ferumoxytol tumor enhancement was noted on post-contrast scans compared to pre-contrast scans ( P = 0.036). Bone sarcomas and lymphomas demonstrated significantly different MRI enhancement and TAM density ( P < 0.05). Within each tumor group, T2* signal enhancement on MR images correlated significantly with the density of CD68+ and CD163+ TAM ( P < 0.05). Ferumoxytol-enhanced MRI is immediately clinically applicable and could be used to stratify patients with TAM-rich tumors to immune-targeted therapies and to monitor tumor response to these therapies.

This retrospective study compared the clinical and radiologic outcomes of patients who underwent arthroscopic rotator cuff repairs by the suture-bridge and double-row modified Mason-Allen techniques. From January 2012 to May 2013, 76 consecutive cases of full-thickness rotator cuff tear, 1 to 4 cm in the sagittal plane, for which arthroscopic rotator cuff repair was performed, were included. The suture-bridge technique was used in 37 consecutive shoulders; and the double-row modified Mason-Allen technique, in 39 consecutive shoulders. Clinical outcomes at a minimum of 2 years (mean, 35.7 months) were evaluated postoperatively using the visual analog scale; University of California, Los Angeles Shoulder Scale; American Shoulder and Elbow Surgeons Subjective Shoulder Scale; and Constant score. Postoperative cuff integrity was evaluated at a mean of 17.7 months by magnetic resonance imaging. At the final follow-up, the clinical outcomes improved in both groups (all P < .001) but with no significant differences between the 2 groups (all P > .05). The retear rate was 18.9% in the shoulders subjected to suture-bridge repair and 12.8% in the double-row modified Mason-Allen group; the difference was not significant (P = .361). Despite the presence of fewer suture anchors, the patients who underwent double-row modified Mason-Allen repair had comparable shoulder functional outcomes and a comparable retear rate with those who underwent suture-bridge repair. Therefore, the double-row modified Mason-Allen repair technique can be considered an effective treatment for patients with medium- to large-sized full-thickness rotator cuff tears.

To analyse clinical outcomes of three types of pelvic surgery for the correction of female mixed or stress urinary incontinence. Women who underwent surgery for urinary incontinence between January 2000 and June 2010 were included in the study (n = 268). Patients were nonrandomly assigned to undergo colporrhaphy, suspension procedure or sling procedure according to their clinical situation. Perioperative parameters were recorded. Short- (< 5 years) and long-term (5-10 years) success rates were determined for each group. The short- and long-term complete cure rates were significantly lower, and the duration of catheterization significantly longer, in patients who underwent colporrhaphy compared with both other groups, but there were no significant differences between suspension or sling procedures. Sling and suspension procedures were equally effective in this study, and both were preferable to colporrhaphy.

To determine the usage of otolaryngology services by children with cleft palate at a pediatric tertiary care facility. Retrospective case series. Specialty clinic at a pediatric tertiary care hospital. Children born between January 1, 1999, and December 31, 2002, with the diagnosis of cleft palate or cleft lip and palate. A total of 41 female and 48 male patients were included. Total number of otolaryngology clinic visits and total number of otolaryngologic surgeries (tympanostomy tube placements and other otologic or upper airway procedures). In the first 5 years of life, these children utilized an average of 8.2 otolaryngology clinic visits (SD = 5.0; range: 1-22) and underwent 3.3 tympanostomy tube surgeries (SD = 2.0; range: 0-10). Seventy-three had their first tube placed at the time of palate repair, and 4 at the time of lip repair. Fifty-one (57.3%) required other otologic or upper airway procedures, including tonsillectomy and/or adenoidectomy (27 children), removal of tympanostomy tubes (24 children), tympanomastoidectomy (3 children), and tympanoplasty (14 children). Of the children who underwent other procedures, they underwent a mean of 1.67 (SD = 0.84; range: 1-4) surgeries. Children with cleft palate are at increased risk for eustachian tube dysfunction, frequently utilize otolaryngology care, and typically receive multiple sets of tympanostomy tubes. This study found that children with cleft palate receive on average of approximately 3 sets of tympanostomy tubes, and the majority required another otologic or upper airway surgery.

Penile fracture is rare, but it is a urological emergency that always requires immediate attention. Moreover, penile fracture has been reported more frequently in recent years. It may have devastating physical, functional, and psychological consequences if not properly managed in time. The objective of this study was to highlight the causes, clinical presentation, and outcomes of cases of penile fracture. This was a prospective observational study extending from November 2012 to November 2014. Each patient underwent a thorough clinical evaluation and received proper treatment. Twenty patients with penile fracture, aged 19 to 56 years (mean, 28 years) were evaluated in this study. Vaginal intercourse was the most common mechanism of injury. Most of the patients (95%) were diagnosed clinically with a proper history and clinical examination. Nineteen patients were treated surgically. The patients underwent six months of follow-up, and were evaluated with local examinations, questionnaires, and colour Doppler ultrasonography as necessary. Although penile fracture is an under-reported urological emergency, its incidence is increasing. It is usually diagnosed based on a clinical examination, but ultrasonography can be very helpful in diagnosis. Especially in cases where treatment is delayed, surgery is preferable to conservative management, because it is associated with better outcomes and fewer long-term complications.

Anastomotic leak after laparoscopic Roux-en-Y gastric bypass (LGB) is a major complication that must be recognized and treated early for best results. There is controversy in the literature regarding the reliability of upper GI series (UGI) in diagnosing leaks. LGB was performed in patients meeting NIH criteria for the surgical treatment of morbid obesity. All leaks identified at the time of surgery were repaired with suture and retested. Drains were placed at the surgeon's discretion. Postoperatively, UGI was performed by an experienced radiologist if there was a clinical suspicion of leak. From September 2001 until October 2004, a total of 553 patients (age 40.4 +/- 9.2 years, BMI 48.6 +/- 7.2) underwent LGB at UAB. Seventy-eight per cent (431 of 553) of patients had no clinical evidence suggesting anastomotic leak and were managed expectantly. Twenty-two per cent (122 of 553) of patients met at least one inclusion criteria for leak and underwent UGI. Four of 122 patients (3.2%) had a leak, two from anastomosis and two from the perforation of the stapled end of the Roux limb. No patient returned to the operating room without a positive UGI. High clinical suspicion and selectively performed UGI based on clinical evidence is reliable in detecting leaks.

Our institution has recently developed a rapid access outpatient clinic to investigate men with testicular lumps and/or pain suspicious for testicular cancer (TCa). To present our experience after 12 months. All referrals to the rapid access testicular clinic (RATC) clinic were prospectively analysed from 01/01/2013 to 01/01/2014. The primary outcome variable was incidence of TCa in the referred patient cohort. Secondary outcome variables were waiting times prior to clinical review and waiting times prior to radical orchidectomy in patients diagnosed with TCa. Seventy-four new patients were referred to the RATC during the 1-year period and the mean age was 34 (range 15-81 years). TCa was the most common diagnosis and was found in 18 (25 %) patients. Patients diagnosed with TCa underwent radical orchidectomy, a median of 3 (range 1-5) days after their initial GP referral. Patients requiring surgical intervention for benign scrotal pathology underwent their procedure a median of 32 (range 3-61) days after their initial referral. Of the 18 patients diagnosed with TCa, 9 (50 %) were diagnosed with a seminomatous germ cell tumour on histopathology. The RATC is a new initiative in Ireland that provides expedient and definitive treatment of patients with newly diagnosed TCa. Early treatment will ultimately improve long-term prognosis in this patient cohort.

Many patients with stage I-II pancreatic adenocarcinoma do not undergo resection. We hypothesized that (1) clinical staging underestimates nodal involvement, causing stage IIB to have a greater percent of resected patients and (2) this stage-shift causes discrepancies in observed survival. The Surveillance, Epidemiology, and End Results (SEER) research database was used to evaluate cause-specific survival in patients with pancreatic adenocarcinoma from 2004-2012. Survival was compared using the log-rank test. Single-center data on 105 patients who underwent resection of pancreatic adenocarcinoma without neoadjuvant treatment were used to compare clinical and pathologic nodal staging. In SEER data, medium-term survival in stage IIB was superior to IB and IIA, with median cause-specific survival of 14, 9, and 11 months, respectively (P < .001). Seventy-two percent of stage IIB patients underwent resection vs 28% in IB and 36% in IIA (P < .001). In our institutional data, 12.4% of patients had clinical evidence of nodal involvement vs 69.5% by pathologic staging (P < .001). Among clinical stage IA-IIA patients, 71.6% had nodal involvement by pathologic staging. Both SEER and institutional data support substantial underestimation of nodal involvement by clinical staging. This finding has implications in decisions regarding neoadjuvant therapy and analysis of outcomes in the absence of pathologic staging. Copyright © 2017 Elsevier Inc. All rights reserved.

Current challenges exist to widespread clinical implementation of genomic medicine and pharmacogenetics. The University of Florida (UF) Health Personalized Medicine Program (PMP) is a pharmacist-led, multidisciplinary initiative created in 2011 within the UF Clinical Translational Science Institute. Initial efforts focused on pharmacogenetics, with long-term goals to include expansion to disease-risk prediction and disease stratification. Herein we describe the processes for development of the program, the challenges that were encountered and the clinical acceptance by clinicians of the genomic medicine implementation. The initial clinical implementation of the UF PMP began in June 2012 and targeted clopidogrel use and the CYP2C19 genotype in patients undergoing left heart catheterization and percutaneous-coronary intervention (PCI). After 1 year, 1,097 patients undergoing left heart catheterization were genotyped preemptively, and 291 of those underwent subsequent PCI. Genotype results were reported to the medical record for 100% of genotyped patients. Eighty patients who underwent PCI had an actionable genotype, with drug therapy changes implemented in 56 individuals. Average turnaround time from blood draw to genotype result entry in the medical record was 3.5 business days. Seven different third party payors, including Medicare, reimbursed for the test during the first month of billing, with an 85% reimbursement rate for outpatient claims that were submitted in the first month. These data highlight multiple levels of success in clinical implementation of genomic medicine. © 2014 Wiley Periodicals, Inc.

To determine the prevalence of nonneoplastic middle ear disease among cats undergoing necropsy and the prevalence of clinical abnormalities in cats in which nonneoplastic middle ear disease was identified. Retrospective case series. 59 cats that underwent necropsy between January 1991 and August 2007. Medical records were searched to identify cats in which nonneoplastic middle ear disease was identified at necropsy. For cats included in the study, data that were recorded included signalment, initial complaint, whether the cat had any clinical signs of middle or external ear disease, whether the cat had upper respiratory tract disease, necropsy diagnosis, gross appearance of the bullae, and reason for euthanasia. Signs of middle ear disease that were considered included unilateral peripheral vestibular disease without motor deficits, Horner syndrome, and facial nerve paralysis. Of the 3,442 cats that underwent necropsy during the study period, 59 (1.7%) had nonneoplastic middle ear disease. Six of the 59 (10%) cats, including 1 cat that was affected bilaterally, had clinical signs of middle ear disease. Of these, 5 had signs of unilateral peripheral vestibular disease, and 1 had Horner syndrome. Results suggested that most cats with nonneoplastic middle ear disease did not have associated clinical signs. Findings may be of clinical relevance for cats in which middle ear disease is identified as an incidental finding during computed tomography or magnetic resonance imaging for unrelated diseases.

The objective of this study was to characterize post-operative outcomes of chemical castration as compared to surgical castration performed by existing municipal field clinics. Fifty-four healthy adult male dogs underwent chemical castration with zinc gluconate solution and 55 healthy adult male dogs underwent surgical castration in veterinary field clinics. Dogs in each group were evaluated for swelling, inflammation, and ulceration (chemical castration) or dehiscence (surgical castration) at Days 3, 7, and 14 following castration. More surgically castrated dogs required medical intervention than chemically castrated dogs (P=0.0328); the number of dogs requiring surgical repair within each group did not differ (P=0.3421). Seven chemically castrated dogs and 22 surgically castrated dogs experienced swelling, inflammation, and/or ulceration; all were managed medically. Two chemically castrated dogs experienced scrotal ulceration requiring surgical castration at Days 3 and 7. One surgically castrated dog experienced partial incisional dehiscence requiring surgical repair at Day 3. Our results suggest that chemical castration of dogs in field clinics is a feasible alternative to surgical castration, but proper follow-up care should be ensured for at least 7days post-procedurally.

Background In 1997, the National Heart, Lung, and Blood Institute of the National Institutes of Health established a Registry to better characterize the demographic, clinical, physiologic and radiographic features of patients with LAM. We report here data collected at enrollment from patients who had either undergone transplant prior to enrollment, underwent transplant during the 5-year study, or were evaluated/waitlisted for lung transplant during the 5-year study. Methods The LAM Registry enrolled patients from six clinical centers between August 1998 and October 2001. On entry patients filled out questionnaires covering medical history, symptoms, treatment and quality of life (SF-36 and St. George’s Respiratory Questionnaire). Enrollees underwent blood laboratory work, arterial blood gases and pulmonary function testing. Follow-up was at six month and/or yearly intervals. Diagnoses were confirmed by biopsy or typical clinical presentation plus CT findings confirmed by independent expert radiologists. A total of 243 women were enrolled. Of those 13 (5.3%) had been transplanted at time of entry (Group A), 21 (8.6%) were transplanted during the study (Group B) and 48 (19.8%) were either waitlisted for transplant or underwent evaluation after enrollment during the study period (Group C). The remaining 161 (66.3%) registrants were neither considered for nor listed for transplant during the Registry period (Group D). Results One-third of patients in a large sample of LAM patients had either been transplanted or were being considered for transplant. At enrollment, patients who had already been transplanted and those not in need of transplant (Groups A and D) had better pulmonary function and quality of life scores compared to patients who subsequently underwent lung transplant during the Registry period (Group B). Conclusion In this large registry of LAM patients, lung transplantation appears to be associated both with significantly improved lung function and quality of life compared to patients with advanced disease.

To evaluate the etiology, presentation, complications and management of chronic pancreatitis in children. Retrospective chart review. Gastroenterology department at Christian Medical College and Hospital, Vellore, India between January 2005 and December 2010. 99 Children (>18 yrs) diagnosed with chronic pancreatitis based on clinical and imaging features. Etiology, clinical presentation, complications and management of chronic pancreatitis in children. Of 3887 children who attended the Gastroenterology department, 99(2.5%) had chronic pancreatitis, of which 60 (60.6%) were males. In 95(95.9%) patients no definite cause was detected and they were labeled as Idiopathic chronic pancreatitis. All patients had abdominal pain, while 9(9.1%) had diabetes mellitus. Of the 22 children tested for stool fat, 10(45.5%) had steatorrhea. Pancreatic calcification was seen in 69 (69.7%). 68 (71.6%) patients with idiopathic chronic pancreatitis had calcification. Calcific idiopathic chronic pancreatitis was more frequent in males (67.6% vs. 48.1%, P=0.07), and was more commonly associated with diabetes mellitus (13.2% vs. none, P=0.047) and steatorrhea (61.5% vs. 16.7%, P=0.069). Pseudocyst (17.1%) and ascites (9.1%) were the most common complications. All children were treated with pancreatic enzyme supplements for pain relief. 57 patients were followed up. With enzyme supplementation, pain relief was present in 32 (56.1%) patients. Of those who did not improve, 10 underwent endotherapy and 15 underwent surgery. Follow up of 8 patients who underwent endotherapy, showed that 5 (62.5%) had relief. Follow up of 11 patients who underwent surgery showed that only 3 (27%) had pain relief. There was no death. Idiopathic chronic pancreatitis is the predominant form of chronic pancreatitis in children and adolescents. It can present with or without calcification. The calcific variety is an aggressive disease characterized by early morphological and functional damage to the pancreas.

To evaluate the efficacy of plate fixation on cervical alignment after anterior cervical discectomy and fusion (ACDF) using a stand-alone cage (ACDF-CA), compared to ACDF performed using a cage and plate fixation (ACDF-CP) and ACDF using autologous iliac bone graft and plate fixation (ACDF-AP), for the treatment of one- or two-level cervical degenerative disease. A second objective was to assess the clinical and radiological outcomes between the groups. A total of 247 patients underwent ACDF and were divided into three groups: those who underwent ACDF-CA (n = 76), ACDF-CP (n = 82) or ACDF-AP (n = 89). Fusion rate and time-to-fusion, global cervical and segmental angle, fused segment height, subsidence rate, and clinical outcomes, were measured using the visual analogue scale (VAS), Oswestry Neck Disability Index (NDI), and Robinson's criteria, assessed preoperatively, immediately postoperatively, and at least 24 months, postoperatively. ACDF-AP was associated with the shortest mean time-to-fusion, followed by ACDF-CP and ACDF-CA. Compared to the preoperative status, the fused segment height and segmental angle increased in all groups immediately postoperatively, being well-maintained in patients who underwent ACDF-AP, while decreasing in those who underwent ACDF-CP and ACDF-CA procedures. Global cervical lordosis increased with ACDF-AP, but decreased immediately postoperatively with ACDF-CP and ACDF-CA, and at the final follow-up. Univariate analysis confirmed that a change in fused segment height was positively associated with a change in both segmental and global cervical angles. Clinical outcomes, namely VAS and NDI scores, as well as Robinson's criteria, were comparable among the three techniques. Supplementation with plate fixation, especially using autologous iliac bone graft, is beneficial for maintaining the fused segment height and cervical spine curvature, as well as reducing time-to-fusion and subsidence rate.

Purpose: To evaluate early swallowing after intensity-modulated radiotherapy for head and neck squamous cell carcinoma and determine factors correlating with aspiration and/or stricture. Methods and Materials: Consecutive patients treated with intensity-modulated radiotherapy with or without chemotherapy between September 2004 and August 2006 at the Dana Farber Cancer Institute/Brigham and Women's Hospital were evaluated with institutional review board approval. Patients underwent swallowing evaluation after completion of therapy; including video swallow studies. The clinical- and treatment-related variables were examined for correlation with aspiration or strictures, as well as doses to the larynx, pharyngeal constrictor muscles, and cervical esophagus. The correlation was assessedmore » with logistic regression analysis. Results: A total of 96 patients were evaluated. Their median age was 55 years, and 79 (82%) were men. The primary site of cancer was the oropharynx in 43, hypopharynx/larynx in 17, oral cavity in 13, nasopharynx in 11, maxillary sinus in 2, and unknown primary in 10. Of the 96 patients, 85% underwent definitive RT and 15% postoperative RT. Also, 28 patients underwent induction chemotherapy followed by concurrent chemotherapy, 59 received concurrent chemotherapy, and 9 patients underwent RT alone. The median follow-up was 10 months. Of the 96 patients, 31 (32%) had clinically significant aspiration and 36 (37%) developed a stricture. The radiation dose-volume metrics, including the volume of the larynx receiving {>=}50 Gy (p = 0.04 and p = 0.03, respectively) and volume of the inferior constrictor receiving {>=}50 Gy (p = 0.05 and p = 0.02, respectively) were significantly associated with both aspiration and stricture. The mean larynx dose correlated with aspiration (p = 0.003). Smoking history was the only clinical factor to correlate with stricture (p = 0.05) but not aspiration. Conclusion: Aspiration and stricture are common side effects after intensity-modulated radiotherapy for head-and-neck squamous cell carcinoma. The dose given to the larynx and inferior constrictors correlated with these side effects.« less

Since 2003, a basic health checkup has involved prostate cancer screening with prostate specific antigen (PSA) alone. We investigated the results between 2003 and 2005. Among males aged over 50 years who underwent a basic health checkup, the subjects were those who desired prostate cancer screening. Cancer screening with PSA alone was performed; mass screening or individual screening in hospitals in the city. We employed PSA with respect to age stratification. On the primary screening, written informed consent regarding the analysis of the screening results was obtained. In 2003, there were 15,303 males aged over 50 years in Tatebayashi City. In 2003, 2004, and 2005, 11.8%, 12.2%, and 12.7% of the males underwent PSA screening, respectively. The rate of elevated PSA levels between 2003 and 2005 was 20.6%. Furthermore, 208, 165, and 179 males required secondary screening, and 80.3%, 61.2%, and 55.3% of the males underwent secondary screening, respectively. Of the males who underwent secondary screening, prostate biopsy was performed in 123 (73.2%), 54 (53.5%), and 38 (38.4%). Prostate cancer was detected in 60, 28, and 16 males, respectively. These values corresponded to 3.4%, 1.5%, and 0.8% of the males who underwent primary screening. The incidence of prostate cancer was 1.85% during the 3 years, and 3.2% in males who underwent the initial health checkup. Of 101 males in whom the stage was evaluated, the clinical stage was evaluated as B in 86 (85.1%), C in 9 (8.9%), and D in 6 (5.9%). Of the 101 males, endocrine therapy was performed in 46 (45.5%), surgery in 31 (30.7%), external irradiation in 5 (5.0%), and followup without treatment in 6 (5.9%). In addition, 7 (6.3%) desired treatment in another hospital, and 6 (5.9%) refused treatment. Prostate cancer was detected in 1.85% of males who underwent primary screening between 2003 and 2005. Of 101 males in whom the stage was evaluated, the clinical stage was evaluated as B in 86 (85.1%), and the early treatment of prostate cancer was achieved. This may lead to a future decrease in the mortality rate.

To assess the clinical usefulness of genetic testing in a pediatric population with inherited retinal disease (IRD). Single-center retrospective case series. Eighty-five unrelated children with a diagnosis of isolated or syndromic IRD who were referred for clinical genetic testing between January 2014 and July 2016. Participants underwent a detailed ophthalmic examination, accompanied by electrodiagnostic testing (EDT) and dysmorphologic assessment where appropriate. Ocular and extraocular features were recorded using Human Phenotype Ontology terms. Subsequently, multigene panel testing (105 or 177 IRD-associated genes) was performed in an accredited diagnostic laboratory, followed by clinical variant interpretation. Diagnostic yield and clinical usefulness of genetic testing. Overall, 78.8% of patients (n = 67) received a probable molecular diagnosis; 7.5% (n = 5) of these had autosomal dominant disease, 25.4% (n = 17) had X-linked disease, and 67.2% (n = 45) had autosomal recessive disease. In a further 5.9% of patients (n = 5), a single heterozygous ABCA4 variant was identified; all these participants had a spectrum of clinical features consistent with ABCA4 retinopathy. Most participants (84.7%; n = 72) had undergone EDT and 81.9% (n = 59) of these patients received a probable molecular diagnosis. The genes most frequently mutated in the present cohort were CACNA1F and ABCA4, accounting for 14.9% (n = 10) and 11.9% (n = 8) of diagnoses respectively. Notably, in many cases, genetic testing helped to distinguish stationary from progressive IRD subtypes and to establish a precise diagnosis in a timely fashion. Multigene panel testing pointed to a molecular diagnosis in 84.7% of children with IRD. The diagnostic yield in the study population was significantly higher compared with that in previously reported unselected IRD cohorts. Approaches similar to the one described herein are expected to become a standard component of care in pediatric ophthalmology. We propose the introduction of genetic testing early in the diagnostic pathway in children with clinical and/or electrophysiologic findings, suggestive of IRD.

2016-10-01

To assess the performance of biochemical markers in the detection of recurrent Cushing disease (CD), as well as the potential benefit of early intervention in recurrent CD patients with elevated late-night salivary cortisol (LNSC) and normal urinary free cortisol (UFC). The design was a single-center, retrospective chart review. Patients treated by the authors from 2008-2013 were included. Recurrence was defined by postsurgical remission of CD with subsequent abnormal LNSC, UFC, or dexamethasone suppression test (DST). We identified 15 patients with postsurgical recurrent CD after initial remission; all but one underwent testing with LNSC, DST, and UFC. Although 12 of 15 patients had normal UFC at time of recurrence, DST was abnormal in 11 of 15, and all 14 patients with LNSC results had ≥1 elevated measurement. Nine patients (7 with normal UFC) showed radiologic evidence of a pituitary tumor at time of recurrence. Among the 14 patients with available follow-up data, 12 have demonstrated significant improvement since receiving treatment. Five patients underwent repeat pituitary surgery and 4 achieved clinical and biochemical remission. Eight patients received mifepristone or cabergoline, and 6 showed clinical and/or biochemical improvement. Three patients (2 with prior mifepristone) underwent bilateral adrenalectomy and 2 demonstrated significant clinical improvements. LNSC is more sensitive than UFC or DST for detection of CD recurrence. Prompt intervention when LNSC is elevated, despite normal UFC, may yield significant clinical benefit for many patients with CD. Early treatment for patients with recurrent CD should be prospectively evaluated, utilizing LNSC elevation as an early biochemical marker. ACTH = adrenocorticotropic hormone CD = Cushing disease CS = Cushing syndrome CV = coefficient of variation DST = dexamethasone suppression test IPSS = inferior petrosal sinus sampling LNSC = late-night salivary cortisol QoL = quality of life TSS = transsphenoidal adenoma resection UFC = urinary free cortisol.

Bryan cervical disc arthroplasty has been reported with satisfactory short- and medium-term clinical results. However, the long-term clinical and radiographic outcomes are seldom reported. The purpose of this study was to compare the eight-year follow-up results in patients who underwent Bryan disc arthroplasty with patients received ACDF, and assess the incidence of heterotopic ossification (HO) and its effect on clinical outcome and mobility of the device. Thirty-one patients underwent Bryan disc arthroplasty, and 35 patients underwent ACDF were included in the study. The Japanese Orthopedic Association (JOA) scores, neck disability index (NDI), visual analogue scale (VAS) of neck and arm pain, and the radiographs were used to evaluate the outcomes. The heterotopic ossification (HO) was determined by CT scan and was classified into three subgroups to compare the related effect. Adjacent segment degeneration (ASD) was also observed. At final follow-up, there were no significant differences in JOA scores between two groups, but the improvement in NDI and neck or arm VAS were significantly greater in the Bryan disc cohort. The range of motion at the index level was 7.0° in Bryan group, while 100 % bone fusion were achieved in ACDF group. HO was observed in 18 (51.4 %) levels. There were more restricted movement of the prosthesis and slight higher rate of axial pain in patients with severe-HO (grade III and IV). Fourteen (28.6 %) levels developed ASD in Bryan group, which was significantly lower than that (58.6 %) in ACDF group. At eight year follow-up, the clinical and radiographic outcomes of Bryan cervical disc arthroplasty compared favorably to those of ACDF. It avoided accelerated adjacent segment degeneration by preserving motion. However, severe HO restricted the ROM of the index levels and maybe associated with post-operative axial pain.

Objective To determine whether compression ultrasonography or clinical examination should be considered as screening tests for the diagnosis of deep vein thrombosis (DVT) after total hip or knee arthroplasty in patients receiving warfarin prophylaxis postoperatively. Design A prospective cohort study. Setting A single tertiary care orthopedic centre. Patients One hundred and eleven patients who underwent elective total hip or knee arthroplasty were enrolled. Postoperatively the warfarin dose was adjusted daily to maintain the international normalized ratio between 1.8 and 2.5. Eighty-six patients successfully completed the study protocol. Intervention Before they were discharged from hospital, patients were assessed for DVT by clinical examination, bilateral compression ultrasonography of the proximal venous system and bilateral contrast venography. Results DVT was found in 29 patients (34%; 95% confidence interval [CI] 24% to 45%), and 6 patients (7%; 95% CI 3% to 15%) had proximal DVT. DVT developed in 18 (40%) of 45 patients who underwent total knee arthroplasty and in 11 (27%) of 41 patients who underwent total hip arthroplasty. The sensitivity of compression ultrasonography for the diagnosis of proximal DVT was 83% (95% CI 36% to 99%) and the specificity was 98% (95% CI 91% to 99%). The positive predictive value of compression ultrasonography was 71%. In contrast, clinical examination for DVT had a sensitivity of 11% (95% CI 2% to 28%) and a positive predictive value of 25%. Conclusions DVT is a common complication after total hip or knee arthroplasty. Compression ultrasonography appears to be a relatively accurate noninvasive test for diagnosing postoperative proximal DVT. In contrast, clinical examination is a very insensitive test. Whether routine use of screening compression ultrasonography will reduce the morbidity of venous thromboembolism after joint arthroplasty requires confirmation in a prospective trial involving long-term follow-up of patients.

2013-08-01

To investigate whether attention to detail is a similarly strong candidate endophenotype of anorexia (AN) and bulimia nervosa (BN), and to explore the incidence and clinical correlates of attention to detail. A total of 266 women (including AN, BN, recovered AN, unaffected sisters of AN/BN & control women) undertook a thorough clinical assessment and were administered two neuropsychological measures of attention to detail (Group Embedded Figure Test; Rey-Osterrieth Complex Figure). Superior attention to detail was found across all AN groups including recovered AN and unaffected AN sisters. Those with BN and their unaffected sisters showed a profile more consistent with poor global integration. The combined effect of superior attention to detail and poor global integration ("weak coherence") was present in 42.3% of active cases and corresponded with a more severe illness, elevated obsessive-compulsive symptoms, and a higher likelihood of comorbid clinical anxiety and self-harm. Attention to detail is a stronger candidate endophenotype of AN compared to BN, where poor global integration may be more relevant. The unique contribution of both aspects of weak coherence (superior attention to detail/poor global integration) requires further exploration and understanding in both eating disorders. Integrating cognitive remediation of these traits into treatment for the subset of patients it is relevant for may improve outcome.

Macular coloboma is a rare entity and its concomitance with Usher syndrome is described here. A 14 years male child was studied in detail along with other family members. He underwent two complete ophthalmologic examinations (4-years follow-up), including visual assessment, orthoptic evaluation, colour vision test, visual fields, corneal topography, Optical coherence tomography, fluorescein angiography, and electroretinography. Detailed ophthalmic examination was also conducted on other asymptomatic members of the same family. Patient had sensorineural deafness, poor visual acuity, and progressive visual field impairment in both eyes, bilaterally presenting macular coloboma and atypical retinitis pigmentosa pattern. The other investigated relatives did not show any specific and/or significant ocular disorder. This concurrence represents no genetic pattern and is observed in sporadic cases.

Detailed Clinical Models (DCMs) have been regarded as the basis for retaining computable meaning when data are exchanged between heterogeneous computer systems. To better support clinical cancer data capturing and reporting, there is an emerging need to develop informatics solutions for standards-based clinical models in cancer study domains. The objective of the study is to develop and evaluate a cancer genome study metadata management system that serves as a key infrastructure in supporting clinical information modeling in cancer genome study domains. We leveraged a Semantic Web-based metadata repository enhanced with both ISO11179 metadata standard and Clinical Information Modeling Initiative (CIMI) Reference Model. We used the common data elements (CDEs) defined in The Cancer Genome Atlas (TCGA) data dictionary, and extracted the metadata of the CDEs using the NCI Cancer Data Standards Repository (caDSR) CDE dataset rendered in the Resource Description Framework (RDF). The ITEM/ITEM_GROUP pattern defined in the latest CIMI Reference Model is used to represent reusable model elements (mini-Archetypes). We produced a metadata repository with 38 clinical cancer genome study domains, comprising a rich collection of mini-Archetype pattern instances. We performed a case study of the domain "clinical pharmaceutical" in the TCGA data dictionary and demonstrated enriched data elements in the metadata repository are very useful in support of building detailed clinical models. Our informatics approach leveraging Semantic Web technologies provides an effective way to build a CIMI-compliant metadata repository that would facilitate the detailed clinical modeling to support use cases beyond TCGA in clinical cancer study domains.

Pre-surgical investigation of digital flexor tendon sheath pathology remains challenging with current standard imaging techniques. The aim of this prospective, anatomical, pilot study was to describe the anatomy of the equine hind limb digital flexor tendon sheath using a combination of computed tomography (CT) and computed tomographic contrast tenography in clinically normal cadaver limbs. Ten pairs of hind limbs with no external abnormalities were examined from the level of the tarsometatarsal joint distally. Limbs initially underwent non-contrast CT examination using 120 kVp, 300 mAs, and 1.5 mm slice thickness. Sixty millilitres of ioversol iodinated contrast media and saline (final concentration 100 mg/ml) were injected using a basilar sesamoidean approach. The computed tomographic contrast tenography examination was then repeated, before dissection of the specimens to compare gross and imaging findings. The combined CT and computed tomographic contrast tenography examinations provided excellent anatomical detail of intra-thecal structures. The borders of the superficial and deep digital flexor tendons, and the manica flexoria were consistently identifiable in all limbs. Detailed anatomy including that of the mesotenons, two of which are previously undescribed, and the plantar annular ligament were also consistently identifiable. Dissection of all 10 pairs of limbs revealed there to be no pathology, in accordance with the imaging findings. In conclusion, the combination of CT and computed tomographic contrast tenography may be useful adjunctive diagnostic techniques to define digital flexor tendon sheath pathology prior to surgical exploration in horses. © 2017 American College of Veterinary Radiology.

Devices enabling long-term intracranial pressure monitoring have been demanded for some time. The first solutions using telemetry were proposed in 1967. Since then, many other wireless systems have followed but some technical restrictions have led to unacceptable measurement uncertainties. In 2009, a completely revised telemetric pressure device called Neurovent P-tel was introduced to the market. This report reviews technical aspects, handling, possibilities of data analysis, and the efficiency of the probe in clinical routine. The telemetric device consists of 3 main parts: the passive implant, the active antenna, and the storage monitor. The implant with its parenchymal pressure transducer is inserted via a frontal burr hole. Pressure values can be registered with a frequency of 1 Hz or 5 Hz. Telemetrically gathered data can be viewed on the storage monitor or saved on a computer for detailed analyses. A total of 247 patients with suspected (n = 123) or known (n = 124) intracranial pressure disorders underwent insertion of the telemetric pressure probe. A detailed analysis of the long-term intracranial pressure profile including mean values, maximum and negative peaks, pathologic slow waves, and pulse pressure amplitudes is feasible using the detection rate of 5 Hz. This enables the verification of suspected diagnoses as normal-pressure hydrocephalus, benign intracranial hypertension, shunt malfunction, or shunt overdrainage. Long-term application also facilitates postoperative surveillance and supports valve adjustments of shunt-treated patients. The presented telemetric measurement system is a valuable and effective diagnostic tool in selected cases. Copyright © 2016 Elsevier Inc. All rights reserved.

Tracheal stenosis is a complex condition caused by altered inflammatory response to injury and subsequent excessive circumferential scar formation. Surgical resection, wherever possible, offers the best long-term results. Nonsurgical methods provide immediate relief to all can be curative in few but mostly serve as an excellent bridge to surgery in majority. The purpose of this study is to retrospectively evaluate the outcome following surgery for benign tracheal stenosis at our center. This retrospective analysis was conducted on 18 patients who underwent resection and anastomosis for tracheal stenosis at our center between March 2012 and December 2015. Their records were analyzed for demography, history, clinical presentation, computed tomography, bronchoscopy details, preoperative interventions, indications for and details of surgery, the procedure performed, postoperative complications, and course during 6 months follow-up. The patients had a varied list of pathologies for which they were either intubated or tracheostomized. The length of stenosis ranged between 1 cm and 4 cm. The diameter of stenotic segment ranged between 0 mm and 10 mm. Average length of resected segment was 3 cm, and number of tracheal rings resected ranged from 2 to 9. Postoperative complications occurred in four patients (22.22%). All our patients were in the "excellent outcome" category at discharge as well as at 3 months follow-up. Surgical management of tracheal stenosis is challenging and requires multidisciplinary team approach. Thorough preoperative preparation and multidisciplinary planning regarding need for and timing of surgery, meticulous intraoperative technique, and aggressive postoperative care is key to successful surgery, which can provide long-lasting cure to these patients.

A substantial, but highly variable, percentage of women with bacterial vaginosis are said to be asymptomatic. The purpose of this study was to estimate the prevalence of symptoms among women with bacterial vaginosis compared with women without bacterial vaginosis by direct, explicit, and detailed questioning of these women. Women presenting for a routine health care visit at 12 health department clinics in Birmingham, Alabama, were recruited to participate in a longitudinal study of vaginal flora. At the first visit, they underwent a pelvic examination, lower genital tract microbiological evaluation, and an interview that included detailed questions regarding lower genital tract symptoms. The prevalence of symptoms among women with and without bacterial vaginosis (Gram stain score 7 or higher) was compared. Among 2,888 women without gonorrhea, Chlamydia, or trichomonas, 75% of women with and 82% of women without bacterial vaginosis never noted any vaginal odor in the past 6 months (P <.001). The corresponding values were 63% and 65% for never noting vaginal "wetness" (P =.02); 58% and 57% for vaginal discharge (P =.65); 91% and 86% for irritation (P =.004); 88% and 85% for itching (P =.64); and 96% and 94% for dysuria (P =.002), respectively. Cumulatively, 58% of women with bacterial vaginosis noted odor, discharge, and/or wetness in the past 6 months compared with 57% of women without bacterial vaginosis (P =.70). The 2 classic symptoms of bacterial vaginosis discharge and odor are each reported by a minority of women with bacterial vaginosis and are only slightly more prevalent than among women without bacterial vaginosis.

Different types of vaginal fistulas is a relatively uncommon condition in the Western world but very frequent in developing countries. In the past, conventional vaginography was the radiological examination of choice for exploring this condition. CT and MRI are now both used for this purpose. Our objective was to test the feasibility and to explore the potential role of a new CT imaging technique implementing vaginal introitus obstruction and opacification of the vagina with iodine contrast agent, to show patency of a fistula. We describe the technical protocol of CT-vaginography as performed in Geneva University Hospitals, including vaginal catheterization with a Foley catheter and obstruction of the introitus by inflating the balloon of the catheter. We also report three cases of patients with suspected vaginal fistula who underwent CT-vaginography. The examinations were technically successful. In one patient, it revealed the presence of fistulous pathways from the vaginal fornix along the bilateral infected surgical prostheses. In a second patient, it showed a fistula between the vagina and the necrotic cavity of a recurrent cervical cancer. In a third patient, it proved the absence of a suspected vaginal fistula. CT-vaginography is a technically feasible CT protocol that provides anatomical and functional information on clinically suspected vaginal fistulas. Advances in knowledge: After the abandon of conventional vaginography in the era of transaxial imaging, the current modalities of imaging vaginal fistulas provide excellent anatomical detail but less functional information concerning the permeability of a vaginal fistulous pathway. We propose the use of CT-vaginography, a technical protocol that we describe in detail.

Objective: High-energy impact to the head, neck, and shoulder can result in cervical spine as well as brachial plexus injuries. Because cervical spine injuries are more common, this tends to be the initial focus for management. We present a case in which the initial magnetic resonance imaging (MRI) was somewhat misleading and a detailed neurological exam lead to the correct diagnosis. Clinical presentation: A 19-year-old man presented to the hospital following a shoulder injury during football practice. The patient immediately complained of significant pain in his neck, shoulder, and right arm and the inability to move his right arm. He was stabilized in the field for a presumed cervical-spine injury and transported to the emergency department. Intervention: Initial radiographic assessment (C-spine CT, right shoulder x-ray) showed no bony abnormality. MRI of the cervical-spine showed T2 signal change and cord swelling thought to be consistent with a cord contusion. With adequate pain control, a detailed neurological examination was possible and was consistent with an upper brachial plexus avulsion injury that was confirmed by CT myelogram. The patient failed to make significant neurological recovery and he underwent spinal accessory nerve grafting to the suprascapular nerve to restore shoulder abduction and external rotation, while the phrenic nerve was grafted to the musculocutaneous nerve to restore elbow flexion. Conclusion: Cervical spinal-cord injuries and brachial plexus injuries can occur by the same high energy mechanisms and can occur simultaneously. As in this case, MRI findings can be misleading and a detailed physical examination is the key to diagnosis. However, this can be difficult in polytrauma patients with upper extremity injuries, head injuries or concomitant spinal-cord injury. Finally, prompt diagnosis and early surgical renerveration have been associated with better long-term recovery with certain types of injury. PMID:22956928

Introduction: Accelerated partial breast irradiation (APBI) with protons results in a very different acute effect profile than standard whole breast irradiation. We reviewed our initial experience with proton APBI and felt that a detailed description of these effects were needed to permit a common tool to compare experience with this developing technology. Methods: Sixty sequential patients treated with proton APBI on a prospective protocol were evaluated and 43 patients with a minimum six-month follow-up underwent detailed photographic and radiologic analysis. The tumorectomy cavity plus an additional 1.5 cm clinical target volume (CTV) was treated with two or three passively-scattered proton beams to a dose of 34 Gy in 10 fractions in one week. Photographs were taken at the end of radiation, at two weeks, six weeks, and every six months thereafter. Mammography was obtained at six months after radiation and annually thereafter. All visual changes were categorized using the smallest meaningful gradations in findings and are demonstrated herein. All treatment-related mammographic findings are reported. Findings: Visual and mammographic findings showed a clear time-dependent relationship and significant variation between individuals. Peak skin reaction occurred at two to six weeks after completion of therapy. At two weeks most patients had either no visible effects and patchy erythema involving <50% of the treated skin (60%). At six weeks most patients had either patchy erythema involving <50% of the overlying skin (33%) or patchy erythema involving >50% of the treated skin (28%). Only one patient developed any moist desquamation. At six months most patients had no visible skin changes (57%) or a small, circular area of mild hyperpigmentation (33%). Mammographic changes seen at six months were regional skin thickening (40%), residual seroma (14%), localized retraction (26%), and fat necrosis (2%). A subcategorized variant on the CTCAE 4.0 was developed to foster granular recording of these findings. PMID:29642467

Background Post-operative pancreatic fistula (POPF) is a common and potentially devastating complication of pancreas resection. Management of this complication is important to the pancreas surgeon. Objective The aim of the present study was to evaluate whether drain data accurately predicts clinically significant POPF. Methods A prospectively maintained database with daily drain amylase concentrations and output volumes from 177 consecutive pancreatic resections was analysed. Drain data, demographic and operative data were correlated with POPF (ISGPF Grade: A – clinically silent, B – clinically evident, C – severe) to determine predictive factors. Results Twenty-six (46.4%) out of 56 patients who underwent distal pancreatectomy and 52 (43.0%) out of 121 patients who underwent a Whipple procedure developed a POPF (Grade A-C). POPFs were classified as A (24, 42.9%) and C (2, 3.6%) after distal pancreatectomy whereas they were graded as A (35, 28.9%), B (15, 12.4%) and C (2, 1.7%) after Whipple procedures. Drain data analysis was limited to Whipple procedures because only two patients developed a clinically significant leak after distal pancreatectomy. The daily total drain output did not differ between patients with a clinical leak (Grades B/C) and patients without a clinical leak (no leak and Grade A) on post-operative day (POD) 1 to 7. Although the median amylase concentration was significantly higher in patients with a clinical leak on POD 1–6, there was no day that amylase concentration predicted a clinical leak better than simply classifying all patients as ‘no leak’ (maximum accuracy =86.1% on POD 1, expected accuracy by chance =85.6%, kappa =10.2%). Conclusion Drain amylase data in the early post-operative period are not a sensitive or specific predictor of which patients will develop clinically significant POPF after pancreas resection.

The aim of this study was to assess the thorax-rib static method (TRSM), a palpation method for locating the seventh cervical spinous process (C7SP), and to report clinical data on the accuracy of this method and that of the neck flexion-extension method (FEM), using radiography as the gold standard. A single-blinded, cross-sectional diagnostic accuracy study was conducted. One hundred and one participants from a primary-to-tertiary health care center (63 men, 56 ± 17 years of age) had their neck palpated using the FEM and the TRSM. A single examiner performed both the FEM and TRSM in a random sequence. Radiopaque markers were placed at each location with the aid of an ultraviolet lamp. Participants underwent chest radiography for assessment of the superimposed inner body structure, which was located by using either the FEM or the TRSM. Accuracy in identifying the C7SP was 18% and 33% (P = .013) with use of the FEM and the TRSM, respectively. The cumulative accuracy considering both caudal and cephalic directions (C7SP ± 1SP) increased to 58% and 81% (P = .001) with use of the FEM and the TRSM, respectively. Age had a significant effect on the accuracy of FEM (P = .027) but not on the accuracy of TRSM (P = .939). Sex, body mass, body height, and body mass index had no significant effects on the accuracy of both the FEM (P = .209 or higher) and the TRSM (P = .265 or higher). The TRMS located the C7SP more accurately compared with the FEM at any given level of anatomic detail, although both still underperformed in terms of acceptable accuracy for a clinical setting.

This study is retrospective cohort study of data on vocal cord paralysis after aortic arch surgery collected during 14 years at a general hospital. We investigated factors in the development of vocal cord paralysis after aortic arch surgery and the effect of vocal cord paralysis on clinical course and outcome. We reviewed data for 182 patients who underwent aortic arch surgery for aortic arch aneurysm and aortic dissection between 1989 and 2003, of whom 58 patients had proximal aortic repair, 62 had distal arch repair, and 62 had total arch repair. We assessed factors associated with the development of vocal cord paralysis and examined in detail the clinical outcome of patients with vocal cord paralysis. Postoperative vocal cord paralysis occurred in 40 patients. Multiple logistic regression analysis revealed the following risk factors with odds ratios (OR) for vocal cord paralysis: extension of procedures into distal arch (OR, 17.0), chronic dilatation of the aorta at the left subclavian artery (OR, 9.14), and total arch repair (OR, 4.24). Adoption of open-style stent-grafts reduced the incidence of vocal cord paralysis (OR, 0.031). The postoperative occurrence of vocal cord paralysis itself emerges as an independent predictor of pulmonary complications (OR, 4.12) and leads to a longer duration of hospital stay. The risk of vocal cord paralysis after aortic arch surgery depends on surgical factors, such as aneurysmal involvement of the distal arch, or the application of newer, less invasive surgical procedures. Vocal cord paralysis after aortic arch surgery itself, under aggressive postoperative respiratory management, did not increase aspiration pneumonia but was associated with postoperative complications leading to higher hospital mortality and prolonged hospitalization.

Purpose Activating FGFR2 mutations have been identified in ~10% of endometrioid endometrial cancers (ECs). We have previously reported that mutations in FGFR2 are associated with shorter disease free survival (DFS) in stage I/II EC patients. Here we sought to validate the prognostic importance of FGFR2 mutations in a large, multi-institutional patient cohort. Methods Tumors were collected as part of the GOG 210 clinical trial “Molecular Staging of Endometrial Cancer” where samples underwent rigorous pathological review and had more than three years of detailed clinical follow-up. DNA was extracted and four exons encompassing the FGFR2 mutation hotspots were amplified and sequenced. Results Mutations were identified in 144 of the 973 endometrioid ECs, of which 125 were classified as known activating mutations and were included in the statistical analyses. Consistent with FGFR2 having an association with more aggressive disease, FGFR2 mutations were more common in patients initially diagnosed with stage III/IV EC (29/170;17%) versus stage I/II EC (96/803; 12%; p = 0.07, Chi-square test). Additionally, incidence of progression (progressed, recurred or died from disease) was significantly more prevalent (32/125, 26%) among patients with FGFR2 mutation versus wild type (120/848, 14%; p < 0.001, Chi-square test). Using Cox regression analysis adjusting for known prognostic factors, patients with FGFR2 mutation had significantly (p < 0.025) shorter progression-free survival (PFS; HR 1.903; 95% CI 1.177–3.076) and endometrial cancer specific survival (ECS; HR 2.013; 95% CI 1.096–3.696). Conclusion In summary, our findings suggest that clinical trials testing the efficacy of FGFR inhibitors in the adjuvant setting to prevent recurrence and death are warranted. PMID:28314589

Various retinal manifestations can occur following a febrile illness due to viral, bacterial or protozoal etiology. As there are limited data in the literature, we undertook this study to analyse the clinical presentation of post-fever retinitis due to various etiologies, as well as its course and management. This was a retrospective study of 14 consecutive cases who presented to the Vitreo Retina Department of our hospital over a 1-year period between January 2010 and December 2010. All patients underwent detailed ophthalmic examination and relevant investigations including fundus fluorescein angiography and optical coherence tomography (OCT). Basic and specific investigations were performed as necessary. All patients were given systemic steroids which were tapered based on clinical response. Twenty-one eyes of 14 patients (7 bilateral, 7 unilateral) were studied. Onset of ocular symptoms was approximately 3 weeks after fever. Four patients had specific etiology-one each of chikungunya, enteric fever, malaria and abdominal abscess with pneumococcal pneumonia. The presenting visual acuity of the affected eyes averaged 2/60. Six eyes had relative afferent pupillary defect. All patients had solitary or multiple patches of retinitis at the posterior pole and exudation at the macula. OCT through the lesions revealed inner retinal hyperreflectivity and thickening with after-shadowing. All patients showed improvement in vision with unilateral cases improving to an average of 6/12 and bilateral cases improving to an average of 6/24. Patients also showed resolution of retinitis, macular edema and serous detachment. Post-fever retinitis as a condition manifested approximately 3 weeks after onset of fever. Irrespective of the cause of the fever, clinical presentation of cases was similar with inner retinitis at the posterior pole and a favourable response to steroids, suggesting a possible immunological basis for this condition.

Multidisciplinary treatments have shown to be effective for fibromyalgia. We report detailed functional outcomes of patients with fibromyalgia who attended a 3-month Multidisciplinary treatment program. The hypothesis was that patients would have increased functional status, physical activity level, and exercise regularity after attending this program. We performed a retrospective analysis of a randomized, simple blinded clinical trial. The inclusion criteria consisted of female sex, a diagnosis of fibromyalgia, age 18-60  and 3-8 years of schooling. Measures from the Fibromyalgia Impact Questionnaire (FIQ) and the COOP/WONCA Functional Health Assessment Charts (WONCA) were obtained before and at the end of the treatment and at 3-, 6-, and 12-month follow-ups. Patients recorded their number of steps per day with pedometers. They performed the six-minute walk test (6 MW) before and after treatment. In total, 155 women participated in the study. Their median (interquartile interval) FIQ score was 68.0 (53.0-77.0) at the beginning of the treatment, and the difference between the Multidisciplinary and Control groups was statistically and clinically significant in all of the measures (except the 6-month follow-up). The WONCA charts showed significant clinical improvements in the Multidisciplinary group, with physical fitness in the normal range across almost all values. In that group, steps/day showed more regularity, and the 6 MW results showed improvement of -33.00 (-59.8 to -8.25) m, and the differences from the Control group were statistically significant. The patients who underwent the Multidisciplinary treatment had improved functional status, physical activity level, and exercise regularity. The functional improvements were maintained 1 year after treatment completion.

Sudden cardiac death occurs commonly in the end-stage renal disease population receiving dialysis, with 25% dying of sudden cardiac death over 5 years. Despite this high risk, surprisingly few prospective studies have studied clinical- and dialysis-related risk factors for sudden cardiac death and arrhythmic precursors of sudden cardiac death in end-stage renal disease. We present a brief summary of the risk factors for arrhythmias and sudden cardiac death in persons with end-stage renal disease as the rationale for the Predictors of Arrhythmic and Cardiovascular Risk in End Stage Renal Disease (PACE) study, a prospective cohort study of patients recently initiated on chronic hemodialysis, with the overall goal to understand arrhythmic and sudden cardiac death risk. Participants were screened for eligibility and excluded if they already had a pacemaker or an automatic implantable cardioverter defibrillator. We describe the study aims, design, and data collection of 574 incident hemodialysis participants from the Baltimore region in Maryland, U.S.A.. Participants were recruited from 27 hemodialysis units and underwent detailed clinical, dialysis and cardiovascular evaluation at baseline and follow-up. Cardiovascular phenotyping was conducted on nondialysis days with signal averaged electrocardiogram, echocardiogram, pulse wave velocity, ankle, brachial index, and cardiac computed tomography and angiography conducted at baseline. Participants were followed annually with study visits including electrocardiogram, pulse wave velocity, and ankle brachial index up to 4 years. A biorepository of serum, plasma, DNA, RNA, and nails were collected to study genetic and serologic factors associated with disease. Studies of modifiable risk factors for sudden cardiac death will help set the stage for clinical trials to test therapies to prevent sudden cardiac death in this high-risk population.

Ventricular arrhythmias (VA) originating from a papillary muscle (PM) have recently been described as a distinct clinical entity with peculiar features that make its treatment with catheter ablation challenging. Here, we report our experience using an intracardiac echo-facilitated 3D electroanatomical mapping approach in a case series of patients undergoing ablation for PM VA. Sixteen patients who underwent catheter ablation for ventricular tachycardia (VT) or symptomatic premature ventricular contractions originating from left ventricular PMs were included in the study. A total of 24 procedures (mean 1.5 per patient) were performed: 15 using a retrograde aortic approach and 9 using a transseptal approach. Integrated intracardiac ultrasound for 3D electroanatomical mapping was used in 15 of the 24 procedures. The posteromedial PM was the most frequent culprit for the clinical arrhythmia, and the body was the part of the PM most likely to be the successful site for ablation. The site of ablation was identified based on the best pace map matching the clinical arrhythmia and the site of earliest the activation. At a mean follow-up of 10.5 ± 7 months, only two patients had recurrent arrhythmias following a repeat ablation procedure. An echo-facilitated 3D electroanatomical mapping allows for real-time creation of precise geometries of cardiac chambers and endocavitary structures. This is useful during procedures such as catheter ablation of VAs originating from PMs, which require detailed representation of anatomical landmarks. Routine adoption of this technique should be considered to improve outcomes of PM VA ablation. Published on behalf of the European Society of Cardiology. All rights reserved. © The Author 2016.

Fixed orthodontic appliances (FOA) temporarily interfere with periodontal health of patients, as the appliance complicates oral hygiene. The use of aligners in orthodontic therapy increased strongly during the last decade. In the literature, the reports about effects of aligner treatment on oral hygiene and gingival conditions are scarce. This cross-sectional study evaluated oral hygiene and patient's satisfaction during orthodontic treatment of patients with FOA or Invisalign®. 100 patients (FOA = 50, Invisalign® = 50) were included who underwent orthodontic treatment for more than 6 months. Clinical examinations were performed to evaluate patients' periodontal condition and were compared with clinical data at the beginning of the orthodontic treatment. Oral hygiene, patients' satisfaction and dietary habits were documented by a detailed questionnaire. For statistical analysis, the Mann-Whitney U-Test and Fisher's Exact Test were used; as multiple testing was applied, a Bonferroni correction was performed. At the time of clinical examinations, patients with FOA were in orthodontic therapy for 12.9 ± 7.2 months, whereas patients with Invisalign® were in orthodontic therapy for 12.6 ± 7.4 months. Significantly better gingival health conditions were recorded in Invisalign® patients (GI: 0.54 ± 0.50 for FOA versus 0.35 ± 0.34 for Invisalign®; SBI: 15.2 ± 7.6 for FOA versus 7.6 ± 4.1 for Invisalign®), whereas the amount of dental plaque was also less but not significantly different (API: 37.7 % ± 21.9 for FOA versus 27.8 % ± 24.6 for Invisalign®). The evaluation of the questionnaire showed greater patients' satisfaction in patients treated with Invisalign® than with FOA. Patients treated with Invisalign® have a better periodontal health and greater satisfaction during orthodontic treatment than patients treated with FOA.

Introduction Different types of thyroiditis may share some parallel clinical and biochemical features. Timely intervention can significantly reduce morbidity and mortality. Aim Aim of this study is to find the frequency of various thyroiditis, study the cytomorphological features and correlate with clinical findings including radiological findings, thyroid function test, and anti-thyroid peroxidase antibodies (Anti-TPO antibodies). Materials and Methods The study included consecutive 110 cases of thyroiditis. Detailed cytomorphological features were studied and correlated with ultrasonography findings, thyroid function test, anti-thyroid peroxidase antibodies (anti-TPO) and histopathological features where thyroidectomy specimens were received for histopathological examination. Results The majority were Hashimoto's thyroiditis (n = 100) and females (n = 103). Other forms of thyroiditis were Hashimoto's thyroiditis with colloid goiter (n = 5), De Quervain's thyroiditis (n = 3), and one case each of postpartum thyroiditis and Hashimoto's thyroiditis with associated malignancy. The majority of patients were in the age group of 21–40 (n = 70) and the majority (n = 73) had diffuse enlargement of thyroid. The majority of patients were hypothyroid (n = 52). The serum anti-TPO antibodies were elevated in 47 patients out of 71 patients. In the 48 patients who underwent ultrasonography, 38 were diagnosed as having thyroiditis. The most consistent cytomorphological features seen in fine-needle aspiration smears of Hashimoto's thyroiditis were increased background lymphocytes, lymphocytic infiltration of thyroid follicular cell clusters, and Hurthle cells. Conclusion The diagnostic cytological features in Hashimoto's thyroiditis are increased background lymphocytes, lymphocytic infiltration of thyroid follicular cell clusters, and Hurthle cells. FNAC remains the “Gold Standard” for diagnosing Hashimoto's thyroiditis. Clinical history, thyroid function, and biochemical parameters are the key for diagnosis of other forms of thyroiditis.

Marfan syndrome (MFS) is a multisystem connective tissue disorder that can lead to aortic dilation requiring aortic root replacement. Neonatal MFS (nMFS) is a rare and severe form of MFS compared to classic MFS (cMFS). Aortic root histology in MFS is thought to demonstrate predominantly medial degeneration (MD) of a translamellar mucoid extracellular matrix accumulation (MEMA-T) vs. the intralamellar mucoid extracellular matrix accumulation (MEMA-I) seen in other aortopathies. The objective of this study was to describe the clinical and histopathologic features of nMFS and cMFS patients undergoing aortic root replacement. Children with MFS who underwent aortic root replacement between 2000 and 2012 at a single institution were included. Medical records including clinical details, aortic dimensions (Z scores), and histology including MD type were obtained. Statistics were descriptive with univariate analysis of age at surgery and type of MD. Eleven patients, 3 (27%) with nMFS, were included. Root dilation at time of surgery was greater in nMFS compared to cMFS (Z=12.8 vs. 7.6, P=.005), and nMFS patients were younger at time of surgery (7.3 vs. 18.8 years, P=.002). Histology in the nMFS group demonstrated MEMA-I in one and no MD in two. In the cMFS group, there were three with MEMA-T, four with MEMA-I, and one with both types. In summary, nMFS has earlier root dilation often in the absence of MD. Both forms of MD were present in our cohort, and there was no correlation between age at surgery and type of MD.

Neuropathy in association with chronic liver disease, including cirrhosis, is recognized; however, there are differences in the incidence and type of neuropathy reported. The causal relationship of liver disease to neuropathy has been questioned. This study was designed to evaluate the incidence and character of peripheral neuropathy in patients with liver cirrhosis. The effect of alcohol consumption, severity of liver disease and encephalopathy on the incidence and severity of neuropathy were also studied. Patients having an identifiable cause of peripheral neuropathy, except alcohol, were excluded from the study. Patients with evidence of vitamin B12 deficiency or diabetes were also excluded from the study. In this study, 33 patients with liver cirrhosis were evaluated clinically and electrophysiologically to detect any evidence of peripheral neuropathy. Nerve conduction studies were performed in the upper and lower limbs using surface electrodes. These patients also underwent a detailed clinical examination. Clinical signs of peripheral neuropathy were found in seven (21%) patients. Nerve conduction studies were abnormal in 24 (73%) patients. The pattern of involvement was predominantly of an axonal sensory motor polyneuropathy. Neuropathy was found both in patients with alcohol-related and non-alcohol-related cirrhosis. The presence of encephalopathy did not have a significant bearing on the incidence and severity of neuropathy. The neuropathy was also not significantly related to the severity of liver disease. The present study reveals that a significant number of patients with liver cirrhosis show evidence of peripheral neuropathy, which is present regardless of the etiology of cirrhosis, and is subclinical in a majority of these patients. The cause of neuropathy was probably the liver disease itself, as the incidence and severity of neuropathy in the alcohol-related cirrhosis, although higher, was not significantly different from the neuropathy in patients with non-alcohol-related cirrhosis.

To assess the incidence and clinical significance of medial joint line bone bruising following acute ankle inversion injury. Forty-five patients who underwent ankle magnetic resonance imaging (MRI) within 2 weeks of acute ankle inversion injury were included in this prospective study. Integrity of the lateral collateral ligament complex, presence of medial joint line bone bruising, tibio-talar joint effusion, and soft-tissue swelling were documented. Clinical follow-up at 6 months was carried out to determine the impact of injury on length of time out of work, delay in return to normal walking, delay in return to sports activity, and persistence of medial joint line pain. Thirty-seven patients had tears of the anterior talofibular ligament (ATFL). Twenty-six patients had medial joint line bone bruising with altered marrow signal at the medial aspect of the talus and congruent surface of the medial malleolus. A complete ATFL tear was seen in 92% of the patients with medial joint line bone bruising (p = 0.05). Patients with an ATFL tear and medial joint line bone bruising had a longer delay in return to normal walking (p = 0.0002), longer delay in return to sports activity (p = 0.0001), and persistent medial joint line pain (p = 0.0003). There was no statistically significant difference in outcome for the eight patients without ATFL tears. Medial joint line bone bruising following an acute ankle inversion injury was significantly associated with a complete ATFL tear, longer delay in the return to normal walking and sports activity, as well as persistent medial joint line pain. Its presence should prompt detailed assessment of the lateral collateral ligament complex, particularly the ATFL. Copyright © 2013 The Royal College of Radiologists. Published by Elsevier Ltd.

The cerebellar cognitive affective syndrome (CCAS) was first described by Schmahmann and Sherman as a constellation of symptoms including dysexecutive syndrome, spatial cognitive deficit, linguistic deficits and behavioural abnormalities in patients with a lesion in the cerebellum with otherwise normal brain. Neurosurgical patients with cerebellar tumours constitute one of the cohorts in which the CCAS has been described. In this paper, we present a critical review of the literature of this syndrome in neurosurgical patients. Thereafter, we present a prospective clinical study of 10 patients who underwent posterior fossa tumour resection and had a detailed post-operative neuropsychological, neuropsychiatric and neuroradiological assessment. Because our findings revealed a large number of perioperative neuroradiological confounding variables, we reviewed the neuroimaging of a further 20 patients to determine their prevalence. Our literature review revealed that study design, methodological quality and sometimes both diagnostic criteria and findings were inconsistent. The neuroimaging study (pre-operative, n = 10; post-operative, n = 10) showed very frequent neuroradiological confounding complications (e.g. hydrocephalus; brainstem compression; supratentorial lesions and post-operative subdural hygroma); the impact of such features had largely been ignored in the literature. Findings from our clinical study showed various degree of deficits in neuropsychological testing (n = 1, memory; n = 3, verbal fluency; n = 3, attention; n = 2, spatial cognition deficits; and n = 1, behavioural changes), but no patient had full-blown features of CCAS. Our study, although limited, finds no robust evidence of the CCAS following surgery. This and our literature review highlight a need for guidelines regarding study design and methodology when attempting to evaluate neurosurgical cases with regard to the potential CCAS.

Cervical spine biopsies can be challenging due to the anatomy and the adjacent critical structures. Percutaneous image-guided biopsies can obviate the need for an open biopsy, however there have been few studies looking at the approaches, safety, and efficacy of percutaneous cervical spine biopsies. This retrospective study evaluated technical considerations, histopathologic and microbiologic yield, and safety in CT-guided cervical bone biopsies. A retrospective review of cervical bone and/or bone/disc biopsies performed from January 2010 to January 2017 was included in this study. Clinical diagnosis and indication, patient demographics, biopsy location, biopsy needle type, technical approach, lesion size, dose-length product, conscious sedation details, complications, and diagnostic histopathologic and/or microbiologic yield were recorded for each case and summarized. A total of 73 patients underwent CT-guided cervical bone biopsies. Fifty-three percent (39/73) were for clinical/imaging concern for infection and 47% (34/73) were for primary tumors or metastatic disease. Thirty-four percent (25/73) were of the inferior cervical spine (ie, C6 and C7). A sufficient sample was obtained for histopathologic and microbiologic analyses in 96% (70/73) of the biopsies. Forty-six percent (18/39) of those samples taken for infection had positive cultures. Two intraprocedural complications occurred in which the patients became hypotensive during the procedure without long-term complications. Percutaneous CT-guided biopsy of the cervical spine is an effective and safe procedure with high diagnostic yield and can obviate open procedures for histopathologic and microbiologic analyses of patients with clinical and imaging findings concerning for infection or primary and metastatic osseous lesions. © 2018 by American Journal of Neuroradiology.

To identify factors influencing outcome in brain arteriovenous malformations (BAVM) treated with endovascular embolization. We also assessed the feasibility of using machine learning techniques to prognosticate and predict outcome and compared this to conventional statistical analyses. A retrospective study of patients undergoing endovascular treatment of BAVM during a 22-year period in a national neuroscience center was performed. Clinical presentation, imaging, procedural details, complications, and outcome were recorded. The data was analyzed with artificial intelligence techniques to identify predictors of outcome and assess accuracy in predicting clinical outcome at final follow-up. One-hundred ninety-nine patients underwent treatment for BAVM with a mean follow-up duration of 63 months. The commonest clinical presentation was intracranial hemorrhage (56%). During the follow-up period, there were 51 further hemorrhagic events, comprising spontaneous hemorrhage (n = 27) and procedural related hemorrhage (n = 24). All spontaneous events occurred in previously embolized BAVMs remote from the procedure. Complications included ischemic stroke in 10%, symptomatic hemorrhage in 9.8%, and mortality rate of 4.7%. Standard regression analysis model had an accuracy of 43% in predicting final outcome (mortality), with the type of treatment complication identified as the most important predictor. The machine learning model showed superior accuracy of 97.5% in predicting outcome and identified the presence or absence of nidal fistulae as the most important factor. BAVMs can be treated successfully by endovascular techniques or combined with surgery and radiosurgery with an acceptable risk profile. Machine learning techniques can predict final outcome with greater accuracy and may help individualize treatment based on key predicting factors. Copyright © 2016 Elsevier Inc. All rights reserved.

Waardenburg syndrome (WS) is a disease of abnormal neural-crest derived melanocyte development characterized by hearing loss and pigmentary disturbances in hair, eyes and skin. WS is subdivided into four major types, WS1-WS4, where WS1 is recognized by the presence of dystopia canthorum, with PAX3 being the only known gene involved. This study aimed at investigating PAX3 mutations and clinical characteristics of WS1 in a group of Iranian patients. A total of 12 WS1 patients from four unrelated Iranian families were enrolled. Waardenburg consortium guidelines were used for WS1 diagnosis. A detailed family history was traced and a thorough clinical examination was performed for all participants. Furthermore, WS1 patients underwent screening for PAX3 mutations using PCR-sequencing. Dystopia canthorum, broad high nasal root and synophrys were observed in all patients. Early graying, hair discoloration, hypoplastic blue eyes (characteristic brilliant blue iris) and hearing loss were the most common features observed, while heterochromia iridis was the least frequently observed sign among the studied Iranian WS1 patients. Genetic analysis of PAX3 revealed four mutations including c.667C>T, c.784C>T, c.951delT and c.451+3A>C. Two of the four mutations reported here (c.951delT and c.451+3A>C) are being reported for the first time in this study. Our data provide insight into genotypic and phenotypic spectrum of WS1 in an Iranian series of patients. Our results expand the spectrum of PAX3 mutations and may have implications for the genetic counseling of WS in Iran. Copyright © 2015 Elsevier B.V. All rights reserved.

The study aim was to document the acute physiological characteristics of swallowing impairment following thermal burn injury. A series of 19 participants admitted to a specialised burn centre with thermal burn injury were identified with suspected aspiration risk by a clinical swallow examination (CSE) conducted by a speech-language pathologist and referred to the study. Once medically stable, each then underwent more detailed assessment using both a CSE and fiberoptic evaluation of swallowing (FEES). FEES confirmed six individuals (32%) had no aspiration risk and were excluded from further analyses. Of the remaining 13, CSE confirmed that two had specific oral-phase deficits due to orofacial scarring and contractures, and all 13 had generalised oromotor weakness. FEES revealed numerous pharyngeal-phase deficits, with the major findings evident in greater than 50% being impaired secretion management, laryngotracheal edema, delayed swallow initiation, impaired sensation, inadequate movement of structures within the hypopharynx and larynx, and diffuse pharyngeal residue. Penetration and/or aspiration occurred in 83% (n = 10/12) of thin fluids trials, with a lack of response to the penetration/aspiration noted in 50% (n = 6/12 penetration aspiration events) of the cases. Most events occurred post swallow. Findings support the fact that individuals with dysphagia post thermal burn present with multiple risk factors for aspiration that appear predominantly related to generalised weakness and inefficiency and further impacted by edema and sensory impairments. Generalised oromotor weakness and orofacial contractures (when present) impact oral-stage swallow function. This study has identified a range of factors that may contribute to both oral- and pharyngeal-stage dysfunction in this clinical population and has highlighted the importance of using a combination of clinical and instrumental assessments to fully understand the influence of burn injury on oral intake and swallowing.

Many valuable classification schemes for saddle nose have been suggested that integrate clinical deformity and treatment; however, there is no consensus regarding the most suitable classification and surgical method for saddle nose correction. To present clinical characteristics and treatment outcome of saddle nose deformity and to propose a modified classification system to better characterize the variety of different saddle nose deformities. The retrospective study included 91 patients who underwent rhinoplasty for correction of saddle nose from April 1, 2003, through December 31, 2011, with a minimum follow-up of 8 months. Saddle nose was classified into 4 types according to a modified classification. Aesthetic outcomes were classified as excellent, good, fair, or poor. Patients underwent minor cosmetic concealment by dorsal augmentation (n = 8) or major septal reconstruction combined with dorsal augmentation (n = 83). Autologous costal cartilages were used in 40 patients (44%), and homologous costal cartilages were used in 5 patients (6%). According to postoperative assessment, 29 patients had excellent, 42 patients had good, 18 patients had fair, and 2 patients had poor aesthetic outcomes. No statistical difference in surgical outcome according to saddle nose classification was observed. Eight patients underwent revision rhinoplasty, owing to recurrence of saddle, wound infection, or warping of the costal cartilage for dorsal augmentation. We introduce a modified saddle nose classification scheme that is simpler and better able to characterize different deformities. Among 91 patients with saddle nose, 20 (22%) had unsuccessful outcomes (fair or poor) and 8 (9%) underwent subsequent revision rhinoplasty. Thus, management of saddle nose deformities remains challenging. 4.

PurposeTo evaluate the effectiveness of transcatheter arterial embolization (TAE) for gastrointestinal (GI) bleeding caused by GI lymphoma.Materials and MethodsThe medical records of 11 patients who underwent TAE for GI bleeding caused by GI lymphoma between 2001 and 2015 were reviewed retrospectively.ResultsA total of 20 TAE procedures were performed. On angiography, contrast extravasation, and both contrast extravasation and tumor staining were seen in 95 % (19/20) and 5 % (1/20) of the procedures, respectively. The most frequently embolized arteries were jejunal (n = 13) and ileal (n = 5) branches. Technical and clinical success rates were 100 % (20/20) and 27 % (3/11), respectively. The causes of clinical failuremore » in eight patients were rebleeding at new sites. In four patients who underwent repeat angiography, the bleeding focus was new each time. Three patients underwent small bowel resection due to rebleeding after one (n = 2) or four (n = 1) times of TAEs. Another two patients underwent small bowel resection due to small bowel ischemia/perforation after three or four times of TAEs. The 30-day mortality rate was 18 % due to hypovolemic shock (n = 1) and multiorgan failure (n = 1).ConclusionAngiogram with TAE shows limited therapeutic efficacy to manage GI lymphoma-related bleeding due to high rebleeding at new sites. Although TAE can be an initial hemostatic measure, surgery should be considered for rebleeding due to possible bowel ischemic complication after repeated TAE procedures.« less

Purpose The present study aimed to evaluate the risk factors and the role of graft material in the development of an acute phase systemic inflammatory response, and the clinical outcome in patients who undergo endovascular aneurysm repair (EVAR) or open surgical repair (OSR) of an abdominal aortic aneurysm (AAA). Methods We retrospectively evaluated the risk factors and the role of graft material in an increased risk of developing systemic inflammatory response syndrome (SIRS), and the clinical outcome in patients who underwent EVAR or OSR of an AAA. Results A total of 308 consecutive patients who underwent AAA repair were included; 178 received EVAR and 130 received OSR. There was no significant difference in the incidence of SIRS between EVAR patients and OSR patients. Regardless of treatment modality, SIRS was observed more frequently in patients treated with woven polyester grafts. Postoperative hospitalization was significantly prolonged in patients that experienced SIRS. In multivariate analyses, the initial white blood cell count (P = 0.001) and the use of woven polyester grafts (P = 0.005) were significantly associated with an increased risk of developing SIRS in patients who underwent EVAR. By contrast, the use of woven polyester grafts was the only factor associated with an increased risk of developing SIRS in patients who underwent OSR, although this was not statistically significant (P = 0.052). Conclusion The current study shows that the graft composition plays a primordial role in the development of SIRS, and it leads to prolonged hospitalization in both EVAR and OSR patients.

To establish the incidence and symptoms of partial seizures in a cohort of patients investigated on account of known sensitivity to intermittent photic stimulation and/or precipitation of seizures by environmental visual stimuli such as television (TV) screens or computer monitors. We report 43 consecutive patients with epilepsy, who had exhibited a significant EEG photoparoxysmal response or who had seizures precipitated by environmental visual stimuli and underwent detailed assessment of their photosensitivity in the EEG laboratory, during which all were questioned concerning their ictal symptoms. All patients were considered on clinical grounds to have an idiopathic epilepsy syndrome. Twenty-eight (65%) patients reported visually precipitated attacks occurring initially with maintained consciousness, in some instances evolving to a period of confusion or to a secondarily generalized seizure. Visual symptoms were most commonly reported and included positive symptoms such as coloured circles or spots, but also blindness and subjective symptoms such as "eyes going funny." Other symptoms described included nonspecific cephalic sensations, deja-vu, auditory hallucinations, nausea, and vomiting. No patient reported any clear spontaneous partial seizures, and there were no grounds for supposing that any had partial epilepsy excepting the ictal phenomenology of some or all of the visually induced attacks. These findings provide clinical support for the physiological studies that indicate that the trigger mechanism for human photosensitivity involves binocularly innervated cells located in the visual cortex. Thus the visual cortex is the seat of the primary epileptogenic process, and the photically triggered discharges and seizures may be regarded as partial with secondary generalization.

Purpose Anterior ischemic optic neuropathy (AION) is an important cause of acute vision loss for which several animal models exist. It has been associated with subretinal fluid in a previous study on patients but not yet so in animal models. Patients and Methods A patient presented with acute non-arteritic AION (NAION) and underwent ophthalmic evaluation and testing including fluorescein angiography and spectral-domain optical coherence tomography (SD-OCT). On the basis of the patient's findings, we used SD-OCT circular and volume scans to analyze retinal changes in a murine model of NAION. Results One week after left eye vision loss, the patient had clinical and imaging findings consistent with NAION. On SD-OCT, there was prominent peripapillary retinal thickening consistent with intra-retinal edema and sub-foveolar fluid. Inspired by the findings in human AION, we looked for similar changes in murine NAION using SD-OCT. The circular scan did not adequately detect the presence of subretinal fluid. Using the 25-line scan, which covered a larger part of the posterior pole, we found that 100% of murine AION resulted in subretinal fluid at day 1. The subretinal fluid resolved by week 1. Conclusion This study detailed a case of clinical NAION associated with intra-retinal and subretinal fluid. We also found that subretinal fluid was common in murine photochemical thrombosis model of AION and could be found far away from the optic disc. PMID:25257770

To elaborate main system characteristics and relevant deployment experiences for the health information system (HIS) Orbis/OpenMed, which is in widespread use in Germany, Austria, and Switzerland. In a deployment phase of 3 years in a 1.200 bed university hospital, where the system underwent significant improvements, the system's functionality and its software design have been analyzed in detail. We focus on an integrated CASE tool for generating embedded clinical applications and for incremental system evolution. We present a participatory and iterative software engineering process developed for efficient utilization of such a tool. The system's functionality is comparable to other commercial products' functionality; its components are embedded in a vendor-specific application framework, and standard interfaces are being used for connecting subsystems. The integrated generator tool is a remarkable feature; it became a key factor of our project. Tool generated applications are workflow enabled and embedded into the overall data base schema. Rapid prototyping and iterative refinement are supported, so application modules can be adapted to the users' work practice. We consider tools supporting an iterative and participatory software engineering process highly relevant for health information system architects. The potential of a system to continuously evolve and to be effectively adapted to changing needs may be more important than sophisticated but hard-coded HIS functionality. More work will focus on HIS software design and on software engineering. Methods and tools are needed for quick and robust adaptation of systems to health care processes and changing requirements.

2014-12-01

Orlistat was approved by the Food and Drug Administration in 1998 and has been shown to be superior to placebo in achieving weight loss. It is generally well tolerated. However, severe liver injury has been reported. We present a case of hepatic failure in a patient taking orlistat. A 54-year-old African-American woman with hypertension presented with hepatic failure. She had noticed increasing fatigue, jaundice and confusion. She used alcohol sparingly and denied tobacco or illicit drug use, but had been taking over-the-counter orlistat for the past two months. Physical examination revealed scleral icterus, jaundice, asterixis and slow speech. Laboratory testing showed markedly abnormal liver function tests with coagulopathy. Acute viral and autoimmune serologies were negative, as was toxicology screen. Liver biopsy showed necrotic hepatic parenchyma likely secondary to drug toxicity. Based upon her clinical presentation and time course, the pattern of liver injury seen on liver biopsy and lack of an alternative plausible explanation, her liver failure was most likely associated with orlistat use. She continued to deteriorate and ultimately underwent orthotopic liver transplantation. Fourteen cases of severe liver injury associated with orlistat use have been reported, four of which are detailed in the literature. This is the second published case of liver failure associated with over-the-counter orlistat usage. Clinicians should be aware of the growing number of cases associating liver injury and orlistat use and carefully monitor their patients on this medication for signs of hepatic dysfunction. © 2014 The Authors.

To analyze the clinical biological characteristics and investigate the managements of familial papillary thyroid carcinoma (FPTC). Clinical data of 36 patients with PTC from 15 families were retrospectively analyzed compared with 95 control cases taken randomly from the patients with sporadic PTC diagnosed and treated in Tianjin Cancer Hospital between January 2010 and August 2011. Of the 36 patients with FPTC, 15 (41.7%) were ≥45 years old, 12 (33.3%) had bilateral carcinoma, 20 (55.6%) were multifocality, 27 (75.0%) had neck lymph node metastases, 17 (47.2%) coexisted thyroid benign tumors. Of the 95 patients with SPTC, 60 (63.2%) were ≥45 years old, 12(12.6%)had bilateral carcinomas, 21 (22.1%) were multifocality, 51 (53.7%) had neck lymph node metastases, and 26(27.4%)coexisted thyroid benign tumors. Of the 36 patients with FPTC, 22 (61.1%) underwent total thyroidectomy and 14 (38.9%) with unilateral thyroidectomy plus isthmusectomy, 3 (8.3%) received unilateral or bilateral lateral neck dissection and central compartment neck dissection (CND), 7 (19.4%) received unilateral or bilateral posterolateral neck dissection and CND, 6 (16.6%) received posterolateral neck dissection and bilateral CND, and 20 (55.6%) received unilateral or bilateral CND. Age at disease presentation of FPTC was younger than that of SPTC. FPTC has higher rates of multifocality and bilateral carcinoma coexisting with thyroid benign tumor than those of SPTC. It necessary to take family history in detail and to evaluate diseases before operation.

Objective Routine use of prophylactic antiepileptic drugs (AED) has been debated. We retrospectively evaluated the effects of prophylactic AED on clinical outcomes in patients with a good clinical grade suffering from aneurysmal subarachnoid hemorrhage (aSAH). Materials and Methods Between September 2012 and December 2014, 84 patients who met the following criteria were included: (1) presence of a ruptured aneurysm; (2) Hunt-Hess grade 1, 2, or 3; and (3) without seizure presentation. Patients were divided into two groups; the AED group (n = 44) and the no AED group (n = 40). Clinical data and outcomes were compared between the two groups. Results Prophylactic AEDs were used more frequently in patients who underwent microsurgery (84.1%) compared to those who underwent endovascular surgery (15.9%, p < 0.001). Regardless of prophylactic AED use, seizure episodes were not observed during the six-month follow-up period. No statistical difference in clinical outcomes at discharge (p = 0.607) and after six months of follow-up (p = 0.178) were between the two groups. After six months, however, favorable outcomes in the no AED group tended to increase and poor outcomes tended to decrease. Conclusion No difference in the clinical outcomes and systemic complications at discharge and after six months of follow-up was observed between the two groups. However, favorable outcomes in the no AED group showed a slight increase after six months. These findings suggest that discontinuation of the current practice of using prophylactic AED might be recommended in patients with a good clinical grade. PMID:26526008

Optic nerve sheath diameter quantification by transbulbar B-mode sonography is a recently validated technique, but its clinical relevance in relapse-free multiple sclerosis patients remains unexplored. In an open-label, comparative, cross-sectional study, we aimed to assess possible differences between patients and healthy controls in terms of optic nerve sheath diameter and its correlation with clinical/paraclinical parameters in this disease. Sixty unselected relapse-free patients and 35 matched healthy controls underwent transbulbar B-mode sonography. Patients underwent routine neurologic examination, brain magnetic resonance imaging and visual evoked potential tests. The mean optic nerve sheath diameter 3 and 5 mm from the eyeball was 22-25% lower in patients than controls and correlated with the Expanded Disability Status Scale (r = -0.34, p = 0.048, and r = -0.32, p = 0.042, respectively). We suggest that optic nerve sheath diameter quantified by transbulbar B-mode sonography should be included in routine assessment of the disease as an extension of the neurologic examination.

In efforts to obtain complete results, current practice in surgical lung biopsy (LB) for interstitial lung disease (ILD) recommends sending lung tissue samples for bacterial, mycobacterial, fungal, and viral cultures. This study assesses the value of this practice by evaluating the microbiology findings obtained from LB for ILD and their associated costs. A total of 296 consecutive patients (140 women, 156 men, median age=61 years) underwent LB for ILD from 2002 to 2009. All had lung tissue sent for microbiology examination. Microbiology results and resultant changes in patient management were analyzed retrospectively. A cost analysis was performed based upon nominal hospital charges adjusted on current inflation rates. Cost data included cultures, stains, smears, direct fluorescent antibody studies, and microbiologist consulting fees. As many as 25 patients (8.4%) underwent open LB and 271 (91.6%) underwent thoracoscopic LB. A total of 592 specimens were assessed (range 1-4 per patient). The most common pathologic diagnoses were idiopathic pulmonary fibrosis in 122 (41.2%), cryptogenic organizing pneumonia in 31 (10.5%), and respiratory bronchiolitis ILD in 16 (5.4%). Microbiology testing was negative in 174 patients (58.8%). A total of 118 of 122 (96.7%) positive results were clinically considered to be contaminants and resulted in no change in clinical management. The most common contaminants were Propionibacterium acnes (38 patients; 31%) and Penicillium fungus (16 patients; 13%). In only four patients (1.4%), the organism cultured (Nocardia one, Histoplasma one, and Aspergillus fumigatus two) resulted in a change in clinical management. The cost of microbiology studies per specimen was $984 (€709), with a total cost for the study cohort being $582,000 (€420,000). The yield and impact on clinical management of microbiology specimens from LB for ILD is very low. Its routine use in LB is questionable. We suggest it should be limited to those cases of ILD with a high suspicion of infection. Substantial cost savings are possible with this change in clinical practice.

Kidney transplantation for amyloidosis remains a contentious issue. Recurrence of amyloidosis is one of the risks of transplantation. Chronic active antibody-mediated rejection is an important cause of chronic allograft dysfunction. A 47-year-old woman underwent kidney transplantation due to renal AA amyloidosis with unknown etiology. Six years posttransplantation, a kidney biopsy showed AA amyloidosis with chronic active antibody-mediated rejection. Donor-specific antibody class II was positive. The patient underwent intravenous plasmapheresis and treatment with rituximab and colchicine. The relationship between recurrence of amyloidosis and rejection was not obvious. Clinical characteristics of kidney transplantation for AA amyloidosis were subjected to literature review and 315 cases were identified. The incidence of amyloidosis recurrence and acute and chronic rejection rates were 15%, 15%, and 8%, respectively. Five-year patient and graft survival rates were 77% and 82%, respectively. Clinical courses of kidney transplantation in AA amyloidosis were, thus, identified.

The aim of this study was to outline the patterns and management of diabetic foot ulcer (DFU) and compare our experience with other published data. All consecutive patients admitted to Al-Jala Hospital with diabetic foot from June, 2008 to May, 2013 were reviewed retrospectively. A total of 542 patients were studied, Wagner's grade III ulcers were the most prevalent (31%), followed by grade II (25%). About 10% of patients underwent major amputations and 24.2% underwent minor amputations. The amputation rate was 34%, and the mortality rate was 2%. Diabetic foot infections cause significant morbidity and mortality among patients with diabetes in Benghazi. There is a need to establish a diabetic foot clinic in Benghazi with a multidisciplinary team to reduce the rates of hospital admission and amputation, as well as hospital stay duration.

The laparoscopic approach to inguinal hernia repair (IHR) has proven beneficial in reducing postoperative pain and facilitating earlier return to normal activity. Except for indications such as recurrent or bilateral inguinal hernias, there remains a paucity of data that specifically identities patient populations that would benefit most from the laparoscopic approach to IHR. Nevertheless, previous experience has shown that obese patients have increased wound morbidity following open surgical procedures. The aim of this study was to investigate the effect of a laparoscopic versus open surgical approach to IHR on early postoperative morbidity and mortality in the obese population using the National Surgical Quality Improvement Program (NSQIP) database. All IHRs were identified within the NSQIP database from 2005 to 2013. Obesity was defined as a body mass index ≥30 kg/m 2 . A propensity score matching technique between the laparoscopic and open approaches was used. Association of obesity with postoperative outcomes was investigated using an adjusted and unadjusted model based on clinically important preoperative variables identified by the propensity scoring system. A total of 7346 patients met inclusion criteria; 5573 patients underwent laparoscopic IHR, while 1773 patients underwent open IHR. On univariate analysis, obese patients who underwent laparoscopic IHR were less likely to experience a deep surgical site infection, wound dehiscence, or return to the operating room compared with those who underwent an open IHR. In both the adjusted and unadjusted propensity score models, there was no difference in outcomes between those who underwent laparoscopic versus open IHR. The laparoscopic approach to IHR in obese patients has similar outcomes as an open approach with regard to 30-day wound events. Preoperative risk stratification of obese patients is important to determining the appropriate surgical approach to IHR. Further studies are needed to investigate the long-term effects of the open and laparoscopic approaches to IHR in the obese population.

Endoscopic resection (ER) is accepted as a curative treatment option for selected cases of early gastric cancer (EGC). Although additional surgery is often recommended for patients who have undergone non-curative ER, clinicians are cautious when managing elderly patients with GC because of comorbid conditions. The aim of the study was to investigate clinical outcomes in elderly patients following non-curative ER with and without additive treatment. Subjects included 365 patients (>75 years old) who were diagnosed with EGC and underwent ER between 2007 and 2015. Clinical outcomes of three patient groups [curative ER (n = 246), non-curative ER with additive treatment (n = 37), non-curative ER without additive treatment (n = 82)] were compared. Among the patients who underwent non-curative ER with additive treatment, 28 received surgery, three received a repeat ER, and six experienced argon plasma coagulation. Patients who underwent non-curative ER alone were significantly older than those who underwent additive treatment. Overall 5-year survival rates in the curative ER, non-curative ER with treatment, and non-curative ER without treatment groups were 84, 86, and 69 %, respectively. No significant difference in overall survival was found between patients in the curative ER and non-curative ER with additive treatment groups. The non-curative ER groups were categorized by lymph node metastasis risk factors to create a high-risk group that exhibited positive lymphovascular invasion or deep submucosal invasion greater than SM2 and a low-risk group without risk factors. Overall 5-year survival rate was lowest (60 %) in the high-risk group with non-curative ER and no additive treatment. Elderly patients who underwent non-curative ER with additive treatment showed better survival outcome than those without treatment. Therefore, especially with LVI or deep submucosal invasion, additive treatment is recommended in patients undergoing non-curative ER, even if they are older than 75 years.

PURPOSE: The purpose of this study was to estimate the risk and economic burden of peristomal skin complications (PSCs) in a large integrated healthcare system in the Midwestern United States. DESIGN: Retrospective cohort study. SUBJECTS AND SETTING: The sample comprised 128 patients; 40% (n = 51) underwent colostomy, 50% (n = 64) underwent ileostomy, and 10% (n = 13) underwent urostomy. Their average age was 60.6 ± 15.6 years at the time of ostomy surgery. METHODS: Using administrative data, we retrospectively identified all patients who underwent colostomy, ileostomy, or urostomy between January 1, 2008, and November 30, 2012. Trained medical abstractors then reviewed the clinical records of these persons to identify those with evidence of PSC within 90 days of ostomy surgery. We then examined levels of healthcare utilization and costs over a 120-day period, beginning with date of surgery, for patients with and without PSC, respectively. Our analyses were principally descriptive in nature. RESULTS: The study cohort comprised 128 patients who underwent ostomy surgery (colostomy, n = 51 [40%]; ileostomy, n = 64 [50%]; urostomy, n = 13 [10%]). Approximately one-third (36.7%) had evidence of a PSC in the 90-day period following surgery (urinary diversion, 7.7%; colostomy, 35.3%; ileostomy, 43.8%). The average time from surgery to PSC was 23.7 ± 20.5 days (mean ± SD). Patients with PSC had index admissions that averaged 21.5 days versus 13.9 days for those without these complications. Corresponding rates of hospital readmission within the 120-day period following surgery were 47% versus 33%, respectively. Total healthcare costs over 120 days were almost $80,000 higher for patients with PSCs. CONCLUSIONS: Approximately one-third of ostomy patients over a 5-year study period had evidence of PSCs within 90 days of surgery. Costs of care were substantially higher for patients with these complications. PMID:28574928

Purpose: To describe how peristomal varices can be successfully embolized via a percutaneous parastomal approach. Methods: The medical records of patients who underwent this procedure between December 1, 2000, and May 31, 2008, were retrospectively reviewed. Procedural details were recorded. Median fluoroscopy time and bleeding-free interval were calculated. Results: Seven patients underwent eight parastomal embolizations. The technical success rate was 88 % (one failure). All embolizations were performed with coils combined with a sclerosant, another embolizing agent, or both. Of the seven successful parastomal embolizations, there were three cases of recurrent bleeding; the median time to rebleeding was 45 daysmore » (range 26-313 days). The remaining four patients did not develop recurrent bleeding during the follow-up period; their median bleeding-free interval was 131 days (range 40-659 days). Conclusion: This case review demonstrated that percutaneous parastomal embolization is a feasible technique to treat bleeding peristomal varices.« less

Recent guidelines classify variable decelerations without detail as to degree of depth. We hypothesized that variable deceleration severity is highly correlated with fetal base deficit accumulation. Seven near-term fetal sheep underwent a series of graded umbilical cord occlusions resulting in mild (30 bpm decrease), moderate (60 bpm decrease), or severe (decrease of 90 bpm to baseline <70 bpm) variable decelerations at 2.5 minute intervals. Mild, moderate, and severe variable decelerations increased fetal base deficit (0.21 ± 0.03, 0.27 ± 0.03, and 0.54 ± 0.09 mEq/L per minute) in direct proportion to severity. During recovery, fetal base deficit cleared at 0.12 mEq/L per minute. In this model, ovine fetuses can tolerate repetitive mild and moderate variable decelerations with minimal change in base deficit and lactate. In contrast, repetitive severe variable decelerations may result in significant base deficit increases, dependent on frequency. Modified guideline differentiation of mild/moderate vs severe variable decelerations may aid in the interpretation of fetal heart rate tracings and optimization of clinical management paradigms.

Cellular therapy is being actively pursued as a therapeutic modality in many of the neurological diseases. A variety of stem cells from diverse sources have been studied in detail and have been shown to exhibit angiogenetic and immunomodulatory properties in addition to other neuroprotective effects. Published clinical data have shown bone marrow mononuclear cell (BMMNC) injection in neurological disorders is safe and possesses regenerative potential. We illustrate a case of 27-year-old male with traumatic brachial plexus injury, administered with autologous BMMNCs intrathecally and intramuscularly, followed by multidisciplinary rehabilitation. At the follow-up assessment of 3 and 7 months after first cell transplantation, improvements were recorded in muscle strength and movements. Electromyography (EMG) performed after the intervention showed a response in biceps and deltoid muscles suggesting the process of reinnervation at the site of injury. In view of the improvements observed after the treatment, the patient underwent second cell transplantation 8 months after the first transplantation. Muscle wasting had completely stopped with an increase in the muscle girth. No adverse effects were noted. Improvements were maintained for 4 years. A comprehensive randomized study for this type of injury is needed to establish the therapeutic benefits of cellular therapy. PMID:29657936

Late-diagnosed bronchial foreign bodies can lead to irreversible changes in the bronchi and the lungs. To date, few reports are available concerning surgical treatment for this condition. The present report summarizes clinicopathological features and surgical treatment options for late-diagnosed bronchial foreign body aspiration. Clinical data of 23 patients who underwent surgical treatment for late-diagnosed bronchial foreign body aspiration in our hospital from 1980 to 2010 were reviewed. The patients included 17 male and six female patients, aged 6 to 66 years. To remove the foreign body, bronchotomy was performed in six patients and pulmonary resection in 17 patients. Foreign bodies were located on the right side in 17 cases and on the left side in six cases. The majority of the foreign bodies were of food origin. Postoperative bronchopleural fistula occurred in two patients. One patient died of renal failure subsequent to lung infections. Detailed history, awareness of potential foreign body aspiration and thorough bronchoscopic examination are helpful to avoid pulmonary resection. However, the latter is necessary in patients with the associated substantial lung lesions to prevent these from progressing into serious lung infections such as pulmonary suppuration or empyema. © 2013 John Wiley & Sons Ltd.

The aim of this study was to perform a 3-year follow-up of primary somatoform vertigo and dizziness (SVD) regarding health care use and treatment. Ninety-two patients with dizziness underwent detailed vestibular neurophysiological testing and a Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition. Psychometric assessments comprised the Vertigo Symptom Scale, the Vertigo Handicap Questionnaire, the SCL-90-R, and the Short-Form-36 Health Survey. At the 3-year follow-up, 65 patients with primary SVD (anxiety, n = 29; depression, n = 14; somatoform disorders, n = 22) were reassessed (70.7% response). The patients improved in symptom severity (p < 0.05), handicap (p < 0.01), and physical quality of life (QoL; p < 0.05) but showed no change in emotional distress. A total of 63.1% (of n = 65) had ongoing SVD. A total of 69.2% (of n = 65) received different forms of treatments. A total of 46.1% (of n = 65) searched redundant medical diagnostic procedures. The patients with decreased coping capacity over time obtained the best prognosis. Primary SVD is an ineffectively treated disorder. Recommendations for specific complaint-oriented psychotherapy programs were given.

Pancreaticoduodenectomy is performed for pancreatic head cancer that originated from the dorsal or ventral primordium. Although the extent of lymph node (LN) dissection is the same irrespective of the origin, the lymphatic continuities may differ between the 2 primordia. Between March 2003 and September 2010, 152 patients underwent pancreaticoduodenectomy for pancreatic cancer. One hundred six patients were assigned into 2 groups according to tumor location on preoperative computed tomography, and their clinical and pathological features were retrospectively analyzed in view of the embryonic development of the pancreas. Sixty of 106 patients were classified with tumors that were derived from the dorsal pancreas (D group) and 46 from the ventral pancreas (V group). The frequency of LN involvement around the middle colic artery (LN 15) in the D group was higher than in the V group (P = 0.008). The rate of additional resection of the pancreas tended to be higher in the D group (P = 0.067). The present study showed the detailed pattern of spread of pancreatic ductal carcinoma to the LNs and provided important information for determining the optimal surgical strategy.

An innovative technique for pancreas transplantation is described. The main aspect consists of the horizontal positioning of the pancreas, which allows a better venous outflow, thus preventing thrombosis and graft loss. The program of pancreas transplantation in this national reference center for pancreatic and liver surgery was started in 2007; the initial results were considered poor, resulting in the loss of half of the grafts due to venous thrombosis. After analyzing the possible causes, this technique was proposed and successfully implemented, reducing the postoperative complications, particularly the problem of venous thrombosis. A detailed description of the new surgical technique is provided. The main clinical and demographic characteristics of the 56 patients who underwent the surgery are analyzed. The incidence of venous thrombosis was 5.3% (3 patients) and graft loss was 3.5% (2 patients). Due to the good results, this technique became the standard surgery for transplantation of the pancreas in our center. The technique proved to be safe and successful. Due to the unique pancreas graft implantation, we called it "transverse pancreas surgery." Copyright © 2017 Elsevier Inc. All rights reserved.

Sonographic evaluation of unexplained pleural exudate: a prospective case series.

Thoracic ultrasound may be helpful in differentiating between malignant and tuberculosis-associated pleural exudate. This study aimed to evaluate its utility in patients with unexplained pleural exudate. Consecutive patients were screened and pleural effusion was found in 278 patients. Pleural exudate was present in 106 patients and remained undiagnosed after biochemical and cytological evaluation in 40 patients (median age 58 years, 67% men) who then underwent detailed thoracic ultrasound for the presence of complex (septated or fibrous) or anechoic patterns. Pleural needle biopsy or thoracoscopy with histological evaluation were used for definitive diagnosis. History, clinical characteristics and routine procedures including cytology were not helpful in differential diagnosis. Pleural specimens for histological evaluation were obtained from all 40 patients and confirmed tuberculosis in 12 patients, cancer in nine and nonspecific pleuritis in 19. Sonographic finding of a complex septal pattern was present only in patients with tuberculosis (positive predictive value 100%); anechoic appearance was suggestive of nonspecific pleuritis (positive predictive value 65%). Thoracic ultrasound is a useful bedside method for differentiation of the etiology of pleural exudate. When a complex septal pattern is found, pleural needle biopsy should be the next diagnostic procedure, whereas with less complex pleural sonography findings other methods should be pursued.

The relationship between early biochemical failure and perineural invasion in pathological T2 prostate cancer.

PubMed

Endrizzi, J; Seay, T

2000-04-01

To evaluate, in patients with pathologically localized prostate cancer, the relationship between early biochemical failure, i.e. an increasing prostate-specific antigen (PSA) level, and perineural invasion (PNI) on final pathology. The records were reviewed of 171 patients with prostate cancer who underwent prostatectomy at one institution between January 1992 and December 1995. Data on the histology, therapy and PSA level were collected and evaluated. Of the 171 patients with pathologically localized (pT2) prostate cancer, 131 were evaluable; 17 (13%) had a detectable PSA level in the first 5 years after surgery and 63 had PNI in the pathological specimen. Of those with PSA recurrence, 14 had PNI, one had no PNI and in two there was no comment on PNI. In comparison, only 10 of the 17 patients with recurrence had a Gleason sum of >/= 7. Perineural invasion seems to be an important predictor of early outcome in patients with organ-confined prostate cancer treated by prostatectomy. In this series it was the most sensitive predictor of biochemical failure. A more detailed pathological evaluation of prostate cancer may allow the clinician to provide closer surveillance and better informed clinical decision-making.

To evaluate the spectrum of PTPN11 gene mutations in Noonan syndrome patients and to study the genotype-phenotype associations. In this study, twenty Noonan syndrome patients with PTPN11 mutations were included. The patients underwent a detailed clinical and physical evaluation. To identify inherited cases, parents of all mutation positive patients were analyzed. Thirteen different PTPN11 mutations, two of them being novel, were detected in the study group. These mutations included eleven missense mutations: p.G60A, p.D61N, p.Y62D, p.Y63C, p.E69Q, p.Q79R, p.Y279C,p.N308D, p.N308S, p.M504V, p.Q510R and two novel missense mutations: p.I56V and p.I282M. The frequency of cardiac abnormalities and short stature were found to be 80 % and 80 %, respectively. Mental retardation was not observed in patients having exon 8 mutations. No significant correlations were detected between other phenotypic features and genotypes. By identifying genotype-phenotype correlations, this study provides information on phenotypes observed in NS patients with different PTPN11 mutations.

While the biological behavior of follicular thyroid carcinoma (FTC) has been studied in great detail using clinical experience, few studies have investigated pre- or intraoperative factors related to the risk of distant metastasis (DM) among patients with FTC. The aim of this study was to analyze the characteristics of FTC with DM. This study retrospectively investigated 102 patients with FTC who underwent surgery between 1988 and 2013. We compared clinicopathological characteristics between FTC with and without DM. Univariate analysis revealed nodal metastasis (p=0.045), serum thyroglobulin (Tg) at initial operation (≥1000ng/ml; p<0.0001), widely invasive appearance according to macroscopic findings (p<0.0001), thick tumor capsule (≥1mm; p<0.0001), vascular invasion (p=0.0003), extrathyroidal invasion (p=0.047), and venous tumor embolism (p=0.045) as significant risk factors for DM. Multivariate analysis conducted using pre- and intraoperative factors identified thick tumor capsule (≥1mm), serum Tg at initial operation (≥1000ng/ml), and macroscopically widely invasive appearance as risk factors independently associated with development of DM. Patients with these risk factors should undergo total thyroidectomy and radioactive iodine ablation. Copyright © 2017 Elsevier B.V. All rights reserved.

This study describes the swallowing function of patients with myotonic dystrophy type 1 (DM1) and the effect of bolus consistency on swallowing in this group. The aim of the study is twofold: (a) to identify which (and to what extent) swallowing variables change for DM1 patients relative to healthy control subjects and (b) to examine whether the degree of oropharyngeal dysphagia is associated with disease severity. Forty-five consecutive DM1 patients and ten healthy subjects underwent a swallowing assessment, at Maastricht University medical Center in the Netherlands. The assessment included a standardized fiberoptic endoscopic evaluation of swallowing (FEES) protocol using different bolus consistencies. Clinical severity of the disease was assessed using the muscular impairment rating scale (MIRS). Significant differences were found between patients and controls for all FEES variables. The magnitude of these differences depended on the bolus consistency. The odds of a more pathological swallowing outcome increased significantly with higher MIRS levels. In conclusion, swallowing function is found to be significantly altered in DM1 patients. The results emphasize the importance of conducting a detailed swallowing assessment in all patients, even those with mild muscle weakness. Copyright © 2014 Elsevier B.V. All rights reserved.

To investigate the age effects of cleft palate repair on middle ear function and hearing level in patients who underwent cleft palate repair at different ages by audiologic examination. Medical histories were gathered in detail, and audiologic tests (ie, tympanometry and pure tone hearing threshold) were conducted in 126 patients after palatoplasty. The patients were divided into the following 4 groups according to their ages when they underwent cleft palate repair: group I (0-3 years, 73 patients), group II (4-7 years, 29 patients), group III (8-11 years, 16 patients), and group IV (12 years and older, 8 patients). The data regarding tympanograms, hearing levels, and the average hearing thresholds of each group were analyzed using chi-square tests. The prevalence of middle ear dysfunction and hearing loss in the patients who underwent palatoplasty before 3 years old (27.4% and 2.0% respectively) was significantly lower than that in patients who underwent palatopalsty at 12 years or older (75.0% and 43.7%, respectively). Linear-by-linear association revealed that the prevalences of middle ear dysfunction and hearing loss among the 4 groups were significantly different ( P < .05). The prevalence of middle ear dysfunction and hearing loss tended to increase with advancing age at the time of cleft palate repair. From an audiologist's perspective, palatoplasty at an early age is very beneficial in helping children with cleft palates acquire better middle ear function and hearing level.

Ventricular septal defect (VSD) with aortic regurgitation (AR) is a well-known association. However, there is still no agreement about its management, particularly regarding the technical details of its operative treatment. The study aim was to describe all components of the syndrome and to evaluate the various techniques used with regards to its anatomical and functional features. A total of 31 patients (mean age 7.4 years; range: 1.0-14.3 years) who underwent repair of VSD and AR between 1990 and 2013 was reviewed. The VSD was perimembranous in 22 patients, and subarterial in nine. Trusler's valvuloplasty technique was used in 15 patients, Yacoub's technique in seven, and Carpentier's technique (triangular resection) in four. Two patients underwent aortic valve replacement (AVR), and three patients with no significant aortic valve lesions underwent a simple patch repair of the VSD. The aortic valvuloplasty results were generally good, with an initial aortic valvuloplasty avoiding AVR. During the immediate postoperative period, valvuloplasty failure occurred in three patients, regardless of the technique used, and all three patients were reoperated on. The mean duration of follow up was 8.5 years (range: 3.2-20.6 years). The initial result was maintained in all patients, except for four who underwent late AVR. The study findings contributed to an analysis of VSD and AR, and helped to clarify the best surgical strategy. The results obtained suggest that adequacy of the initial repair is the most important determinant of subsequent evolution.

Piver, M S; Lele, S B; Gamarra, M

1988-01-01

From February 1982-June 1986, 25 consecutive patients with surgical stage I endometrial adenocarcinoma (no evidence of metastasis at surgery or occult cervical or adnexal involvement on histopathologic review) and malignant peritoneal cytologic washings were treated with progesterone therapy. Twenty-two patients have undergone a second look laparoscopy and repeat cytologic washings, one of those also underwent a third look laparoscopy. Two patients refused second look laparoscopy, and in a third patient laparoscopy was medically contraindicated; all three have no evidence of disease (NED) at 15, 46, and 64 months respectively and are off therapy. Of the 22 patients who underwent second look laparoscopy, 21 (95%) had no macroscopic evidence of recurrent endometrial carcinoma and repeat negative peritoneal cytology; 1 patient (5%) had persistent malignant peritoneal cytology but was NED at third look laparoscopy one year later. All 25 patients are off progesterone therapy and remain clinically NED from 12-64 months. Although progesterone therapy for malignant peritoneal cytology resulted in a 100% reversal of malignant peritoneal cytology to normal in the 22 patients who underwent second or third look laparoscopy and all 25 patients remain clinically NED, the true value of progesterone therapy can only be ascertained by a randomized trial of progesterone versus no therapy.

Surgical treatment for endocarditis patients with a perivalvular abscess is still challenging.Methods and Results:From 2009 to 2016, 470 patients underwent surgery for active endocarditis at 11 hospitals. Of these, 226 patients underwent aortic valve surgery. We compared the clinical results of 162 patients without a perivalvular abscess, 37 patients who required patch reconstruction of the aortic annulus (PR group) and 27 who underwent aortic root replacement (ARR group). Patients with a perivalvular abscess had a greater number ofStaphylococcusspecies and prosthetic valve endocarditis, a greater level of inflammation at diagnosis and symptomatic heart failure before surgery, especially in the ARR group. Nevertheless, the duration between diagnosis and surgery was similar, because of a high prevalence of intracranial hemorrhage in the ARR group. Hospital death occurred in 13 (9%) patients without a perivalvular abscess, in 4 (12%) in the PR and in 7 (32%) in the ARR group. Postoperative inflammation and end-organ function were similar between the groups. Overall survival of patients without a perivalvular abscess and that of the PR group was similar, but was significantly worse in the ARR group (P=0.050, 0.026). Freedom from endocarditis recurrence was similar among all patients. Patients treated with patch reconstruction showed favorable clinical results. Early surgical intervention is necessary when a refractory invasive infection is suspected.

To compare the clinical and second-look arthroscopic outcomes in patients undergoing arthroscopic marrow stimulation combined with lateral sliding calcaneal osteotomy for varus ankle osteoarthritis, with or without adipose-derived mesenchymal stem cell (MSC) injection. In this retrospective comparative study, 49 patients with varus ankle osteoarthritis underwent second-look arthroscopy after arthroscopic marrow stimulation combined with lateral sliding calcaneal osteotomy between January 2010 and November 2012; 23 ankles underwent marrow stimulation alone (group 1), and 26 underwent marrow stimulation with MSC injection (group 2). The decision whether to receive the MSC injection, which was free of charge, was solely up to the patients. Second-look arthroscopies were performed at a mean of 12.5 months and 12.4 months postoperatively in group 1 and group 2, respectively. Clinical outcome measures included a visual analog scale (VAS) score for pain and the American Orthopaedic Foot & Ankle Society (AOFAS) score. The radiologic outcome variable was the talar tilt angle. On second-look arthroscopy, cartilage regeneration was evaluated using the International Cartilage Repair Society (ICRS) grade. The mean VAS score improved significantly from 7.3 ± 0.9 to 3.9 ± 1.2 in group 1 and from 7.4 ± 0.8 to 3.1 ± 1.5 in group 2 at final follow-up (P < .001 for both groups). The mean AOFAS score also improved significantly from 64.4 ± 4.1 to 79.6 ± 7.7 in group 1 and from 63.5 ± 4.2 to 84.2 ± 7.9 in group 2 at final follow-up (P < .001 for both groups). The VAS and AOFAS scores were significantly better in group 2 than in group 1 (P = .040 and P = .047, respectively). ICRS grades were significantly correlated with clinical outcomes in both groups (all P < .05), and there were significant differences in ICRS grades between the groups (P < .05). The mean talar tilt angle improved significantly after lateral sliding calcaneal osteotomy in both groups and was significantly correlated with clinical outcomes and ICRS grade (all P < .05). In patients with varus ankle osteoarthritis who underwent lateral sliding calcaneal osteotomy, significant improvements in VAS and AOFAS scores, as well as better ICRS grades, were achieved at short-term follow-up after marrow stimulation with additional MSC injection compared with after marrow stimulation alone.

Melanoma patients with regional metastatic disease are at high risk for recurrence and metastatic disease, despite radical lymph node dissection (RLND). We investigated the immunologic response and clinical outcome to adjuvant dendritic cell (DC) vaccination in melanoma patients with regional metastatic disease who underwent RLND with curative intent. In this retrospective study, 78 melanoma patients with regional lymph node metastasis who underwent RLND received autologous DCs loaded with gp100 and tyrosinase and were analyzed for functional tumor-specific T cell responses in skin-test infiltrating lymphocytes. The study shows that adjuvant DC vaccination in melanoma patients with regional lymph node metastasis is safe and induced functional tumor-specific T cell responses in 71% of the patients. The presence of functional tumor-specific T cells was correlated with a better 2-year overall survival (OS) rate. OS was significantly higher after adjuvant DC vaccination compared to 209 matched controls who underwent RLND without adjuvant DC vaccination, 63.6 mo vs. 31.0 mo (p = 0.018; hazard ratio 0.59; 95%CI 0.42–0.84). Five-year survival rate increased from 38% to 53% (p < 0.01). In summary, in melanoma patients with regional metastatic disease, who are at high risk for recurrence and metastatic disease after RLND, adjuvant DC vaccination is well tolerated. It induced functional tumor-specific immune responses in the majority of patients and these were related to clinical outcome. OS was significantly higher compared to matched controls. A randomized clinical trial is needed to prospectively validate the efficacy of DC vaccination in the adjuvant setting. PMID:26942068

Hospital de Clínicas de Porto Alegre (HCPA). 102 patients that underwent cold knife conization. Women that underwent cold knife conization of the cervix were randomized to undergo the procedure with or without lateral hemostatic sutures. blood loss measured in grams. operative time and postoperative intervention. Only the participants were blinded to group assignment. From March 2009 to August 2012, patients were randomly assigned to one of the study groups. There were no differences in amount of blood loss between patients that underwent the procedure with and without sutures (p = 0.39). Operative time was shorter in the group without suture (p = 0.020). There were no differences in intervention due to bleeding (p = 0.20). Blood loss was greater among menstruating women than for menopausal women (p = 0.011). There were no differences in amount of blood lost between smoking and nonsmoking patients (p = 0.082). Lateral hemostatic sutures do not affect the amount of intraoperative bleeding or the number of postoperative interventions. Their use is not necessary because they result in longer operative time, have a higher cost due to the use of suture material and pose the risk of ureter lesion in case the sutures are not placed at a lower position in the cervix.

To describe a multicenter experience using an endoscopic suturing device for management of gastrointestinal (GI) defects and stent anchorage. Endoscopic closure of GI defects including perforations, fistulas, and anastomotic leaks as well as stent anchorage has improved with technological advances. An endoscopic suturing device (OverStitch; Apollo Endosurgery Inc.) has been used. Retrospective study of consecutive patients who underwent endoscopic suturing for management of GI defects and/or stent anchorage were enrolled between March 2012 and January 2014 at multiple academic medical centers. Data regarding demographic information and outcomes including long-term success were collected. One hundred and twenty-two patients (mean age, 52.6 y; 64.2% females) underwent endoscopic suturing at 8 centers for stent anchorage (n=47; 38.5%), fistulas (n=40; 32.7%), leaks (n=15; 12.3%), and perforations (n=20; 16.4%). A total of 44.2% underwent prior therapy and 97.5% achieved technical success. Immediate clinical success was achieved in 79.5%. Long-term clinical success was noted in 78.8% with mean follow-up of 68 days. Clinical success was 91.4% in stent anchorage, 93% in perforations, 80% in fistulas, but only 27% in anastomotic leak closure. Endoscopic suturing for management of GI defects and stent anchoring is safe and efficacious. Stent migration after stent anchoring was reduced compared with published data. Long-term success without further intervention was achieved in the majority of patients. The role of endoscopic suturing for repair of anastomotic leaks remains unclear given limited success in this retrospective study.

The aim of this study was to compare the short-term outcomes of arthroscopic TightRope ® fixation with that of hook plate fixation in patients with acute unstable acromioclavicular joint dislocations. We conducted a prospective case-control study of twenty-six patients with an acute ACJ dislocation who underwent surgical repair with either an arthroscopic TightRope ® fixation or a hook plate from 2013 to 2016. Clinical and radiological data were collected prospectively. Clinical outcomes were evaluated using the Constant Score, the University of California at Los Angeles (UCLA) Shoulder Score, Oxford Shoulder Score as well as the visual analogue scale. Radiological outcomes were assessed with the coracoclavicular distance (CCD). Sixteen patients underwent arthroscopic TightRope ® fixation, while 10 patients underwent hook plate fixation. There were no significant differences in the preoperative variables except for the mean UCLA 4b infraspinatus score (TightRope ® 2.8 vs. hook plate 3.8; p = 0.030). Duration of surgery was significantly longer in the TightRope ® group. At 1 year post-operatively, the TightRope ® group had a significantly better Constant Score and CCD with no complications. All patients with hook plate fixation had to undergo a second procedure for removal of implant, and 3 patients had complications. Arthroscopic TightRope ® fixation is a good option for the treatment of acute unstable ACJ dislocations. It has better short-term clinical and radiological outcomes as well as lesser complications when compared to hook plate fixation. Therapeutic, Level III.

The aim of our study is to compare the improvement in clinical outcomes after conventional arthroscopic double-row rotator cuff repair and arthroscopic undersurface rotator cuff repair. A consecutive series of 120 patients who underwent arthroscopic rotator cuff repair was analysed. Sixty-one patients underwent conventional double-row rotator cuff repair and 59 patients underwent undersurface rotator cuff repair. Several clinical outcomes, including numerical pain rating scale (NPRS), constant shoulder score (CSS), Oxford shoulder score (OSS) and University of California Los Angeles shoulder score (UCLASS), were prospectively recorded by a trained healthcare professional preoperatively and at 3, 6, 12 and 24 months after surgery. Comparing both groups, there were no differences in age, gender and preoperative NPRS, CSS, OSS and UCLASS. However, the tear size was 0.7 ± 0.2 (95% confidence interval (CI) 0.3-1.1) cm larger in the conventional group ( p = 0.002). There was no difference in the improvement of NPRS, CSS, OSS and UCLASS at all time points of follow-up, that is, at 3, 6, 12 and 24 months after surgery. The duration of operation was shorter by 35 ± 3 (95% CI 28-42) min in the undersurface group ( p < 0.001). Both arthroscopic undersurface rotator cuff repair and conventional arthroscopic double-row rotator cuff repair showed marked improvements in clinical scores when compared preoperatively, and there was no difference in improvements between both groups. Arthroscopic undersurface rotator cuff repair is a faster technique compared to the conventional arthroscopic double-row rotator cuff repair.

The effectiveness of cancer control is unclear after radical prostatectomy for patients with clinical T3 prostate cancer. We retrospectively reviewed 1409 patients who underwent radical prostatectomy between April 2007 and December 2014, including 210 patients with cT3 prostate cancer. Nine patients who received neoadjuvant hormonal therapy and three patients who were lost to follow-up were excluded from the analysis. Clinical staging was performed by an experienced radiologist using preoperative magnetic resonance imaging findings. We analyzed the predictors of biochemical recurrence using Cox proportional hazard analyses. A total of 113 patients (57%) underwent radical retropubic prostatectomy and 85 patients (43%) underwent robot-assisted radical prostatectomy. The median follow-up period was 36 months. Downstaging occurred for 60 patients (30%), positive surgical margins were identified in 117 patients (59%), and biochemical recurrence was observed for 89 patients (45%). In the multivariate analyses, the independent preoperative predictors of biochemical recurrence were ≥50% proportion of positive biopsy cores [hazard ratio (HR): 2.858, P < 0.0001] and a biopsy Gleason score of ≥8 (HR: 1.800, P = 0.0093). The independent post-operative predictors of biochemical recurrence were positive surgical margins (HR: 2.490, P = 0.0018) and seminal vesicle invasion (HR: 2.750, P < 0.0001). Among patients with cT3 prostate cancer, the percentage of positive biopsy cores and the biopsy Gleason score should be considered to select treatment. Compared with radical retropubic prostatectomy, robot-assisted radical prostatectomy may be a feasible treatment option in this setting.

Pancreatic neuroendocrine tumors (PNETs) account for 1-2% of all pancreatic neoplasms. Nonfunctioning PNETs (NF-PNETs) account for 60-90% of all PNETs. Laparoscopic distal pancreatectomy (LDP) is becoming the treatment of choice for benign lesions in the body and tail of the pancreas. However, LDP has not yet been widely accepted as the gold standard for NF-PNETs. The purpose of this study is to evaluate the clinical and oncologic outcomes after laparoscopic versus open distal pancreatectomy (ODP) for NF-PNETs. Between April 1995 and September 2016, 94 patients with NF-PNETs underwent open or laparoscopic distal pancreatectomy at Samsung Medical Center. Patients were divided into two groups: those who underwent LDP and those who underwent ODP. Both groups were compared in terms of clinical and oncologic variables. LDP patients had a significantly shorter hospital stay compared with ODP patients, amounting to a mean difference of 2 days (p < 0.001). Overall complication rates did not differ significantly between the ODP and LDP groups (p = 0.379). The 3-year overall survival rates in the ODP and LDP groups were 93.7 and 100%, respectively (p = 0.069). In this study, LDP for NF-PNETs had similar oncologic outcomes compared with ODP. In addition, LDP was associated with a shorter hospital stay compared with ODP. Therefore, LDP is a safe and effective procedure for patients with NF-PNETs. A multicenter study and a randomized controlled trial are needed to better assess the clinical and oncologic outcomes.

The purpose of this study was to evaluate potential technical advantages of the CO2 laser technology in mini-open transforaminal lumbar interbody fusion (TLIF) surgeries and report our preliminary clinical data on the safety and clinical outcomes. There is currently no literature discussing the recently redeveloped CO2 laser technology application for lumbar fusion. Safety and clinical outcomes were compared between two groups: 24 patients that underwent CO2 laser-assisted one-level TLIF surgeries and 30 patients that underwent standard one-level TLIF surgeries without the laser. There were no neural thermal injuries or other intraoperative laser-related complications encountered in this cohort of patients. At a mean follow-up of 17.4 months, significantly reduced lower back pain scores (P=0.013) were reported in the laser-assisted patient group compared to a standard fusion patient group. Lower extremity radicular pain intensity scores were similar in both groups. Laser-assisted TLIF surgeries showed a tendency (P = 0.07) of shorter operative times that was not statistically significant. Based on this preliminary clinical report, the safety of the CO2 laser device for lumbar fusion surgeries was assessed. There were no neural thermal injuries or other intraoperative laser-related complications encountered in this cohort of patients. Further investigation of CO2 laser-assisted lumbar fusion procedures is warranted in order to evaluate its effect on clinical outcomes.

To compare clinical assessment of diabetic eye disease by standard dilated examination with data gathered using a smartphone-based store-and-forward teleophthalmology platform. 100 eyes of 50 adult patients with diabetes from a health care safety-net ophthalmology clinic. All patients underwent comprehensive ophthalmic examination. Concurrently, a smartphone was used to estimate near visual acuity and capture anterior and dilated posterior segment photographs, which underwent masked, standardized review. Quantitative comparison of clinic and smartphone-based data using descriptive, kappa, Bland-Altman, and receiver operating characteristic analyses was performed. Smartphone visual acuity was successfully measured in all eyes. Anterior and posterior segment photography was of sufficient quality to grade in 96 and 98 eyes, respectively. There was good correlation between clinical Snellen and smartphone visual acuity measurements (rho = 0.91). Smartphone-acquired fundus photographs demonstrated 91% sensitivity and 99% specificity to detect moderate nonproliferative and worse diabetic retinopathy, with good agreement between clinic and photograph grades (kappa = 0.91 ± 0.1, P < 0.001; AUROC = 0.97, 95% confidence interval, 0.93-1). The authors report a smartphone-based telemedicine system that demonstrated sensitivity and specificity to detect referral-warranted diabetic eye disease as a proof-of-concept. Additional studies are warranted to evaluate this approach to expanding screening for diabetic retinopathy.

To have in-depth analysis of clinical ablation effect of noninvasive radiofrequency field-induced hyperthermia on liver cancer cells, this paper collected liver cancer patients' treatment information from 10 hospitals during January 2010 and December 2011, from which 1050 cases of patients were randomly selected as study object of observation group who underwent noninvasive radiofrequency field-induced hyperthermia treatment; in addition, 500 cases of liver cancer patients were randomly selected as study object of control group who underwent clinical surgical treatment. After treatment was completed, three years of return visit were done, survival rates of the two groups of patients after 1 year, 2 years, and 3 years were compared, and clinical effects of radiofrequency ablation of liver cancer were evaluated. Zoom results show that the two groups are similar in terms of survival rate, and the difference is without statistical significance. 125 patients in observation group had varying degrees of adverse reactions, while 253 patients in control group had adverse reactions. There was difference between groups P < 0.05, with significant statistical significance. It can be concluded that radiofrequency ablation of liver cancer is more secure. Therefore, the results of this study fully demonstrate that liver cancer treatment with noninvasive radiofrequency field-induced hyperthermia is with safety effect and satisfactory survival rate, thus with relatively high clinical value in clinical practice.

The purpose of this study was to evaluate the role of focused assessment with sonography for trauma (FAST) as a triage tool in multiple-casualty incidents (MCIs) for a single international conflict. The charts of 849 casualties that arrived at our level 1 trauma referral center were reviewed. Casualties were initially triaged according to the Injury Severity Score at the emergency department gate. Two-hundred eighty-one physically injured patients, 215 soldiers (76.5%) and 66 civilians (23.5%), were admitted. Focused assessment with sonography for trauma was performed in 102 casualties suspected to have an abdominal injury. Sixty-eight underwent computed tomography (CT); 12 underwent laparotomy; and 28 were kept under clinical observation alone. We compared FAST results against CT, laparotomy, and clinical observation records. Focused assessment with sonography for trauma results were positive in 17 casualties and negative in 85. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of FAST were 75%, 97.6%, 88.2%, 94.1%, and 93.1%, respectively. A strong correlation between FAST and CT results, laparotomy, and clinical observation was obtained (P < .05). In a setting of a war conflict-related MCI, FAST enabled immediate triage of casualties to laparotomy, CT, or clinical observation. Because of its moderate sensitivity, a negative FAST result with strong clinical suspicion demands further evaluation, especially in an MCI.

Brain single-photon emission computed tomography (SPECT) scans indirectly show functional activity via measurement of regional cerebral blood flow. Thirty patients at a community-based psychiatric clinic underwent brain SPECT scans. Changes in scoring of before-treatment and after-treatment scans correlated well with changes in patient Global Assessment of Functioning (GAF) scores before treatment and after treatment. Patients were retrospectively matched with controls with similar diagnoses and pretreatment GAF scores, and those who underwent SPECT-guided treatment improved significantly more than the control patients.

Onyx was developed for embolization of central nervous system AVMs but is increasingly used extracranially because of its unique physical properties. We review our experience and results with the use of Onyx for the treatment of fast-flow extracranial vascular lesions. We retrospectively analyzed clinical and imaging records of 22 patients who underwent 71 extracranial embolizations from March 2007 through January 2010. The diagnoses were the following: cervicofacial AVM (n = 18), traumatic fistula (n = 3), and vessel laceration (n = 1). In 62 of 71 procedures (87%), Onyx was the sole embolic agent; it was delivered transarterially in 67/71 and percutaneously in 4/71 procedures. Clinical goals included amelioration of pain and control of bleeding. The clinical efficacy of embolization was judged by symptom control, and adverse events were assessed by clinical examination and history, both postembolization and 4 weeks postprocedure. Cessation of acute bleeding was achieved in 13/14 cases, with 1 case of immediate recurrent massive epistaxis prompting reintubation and further embolization. Control of subacute bleeding episodes and pain was achieved for all patients. Following staged embolization, 7 patients underwent surgical resection without significant blood loss. Surgeons reported high satisfaction with the intraoperative handling properties of Onyx. Transient swelling, local tenderness, or numbness was encountered after 7 procedures. There were no stuck catheters, vessel dissections, or vessel ruptures and no skin discoloration. Staged Onyx embolization was clinically efficacious in managing extracranial fast-flow vascular malformations and lesions, with low associated morbidity.

Tetanus is a major worldwide health problem, and its global incidence has been estimated to be approximately 1 million cases per year. In particular, tetanus is more frequent in the elderly as compared with adults. We report a case of an octogenarian who presented with dysphagia and tremors as the only clinical symptoms. During hospitalization, the patient's clinical conditions worsened rapidly, and, although in absence of the classic clinical presentation (trisma, nuchal rigidity, and opisthotonus), a diagnosis of tetanus was suspected. Thus, the patient underwent a tetanus immunoglobulin immunization and antibiotic therapy with excellent clinical recovery.

IMPROVING THE REPORTING OF THERAPEUTIC EXERCISE INTERVENTIONS IN REHABILITATION RESEARCH.

The foundation of evidence-based practice lies in clinical research, which is based on the utilization of the scientific method. The scientific method requires that all details of the experiment be provided in publications to support replication of the study in order to evaluate and validate the results. More importantly, clinical research can only be translated into practice when researchers provide explicit details of the study. Too often, rehabilitation exercise intervention studies lack the appropriate detail to allow clinicians to replicate the exercise protocol in their patient populations. Therefore, the purpose of this clinical commentary is to provide guidelines for optimal reporting of therapeutic exercise interventions in rehabilitation research. 5.

Hirschsprungs disease (HD) in adults is extremely rare, only three publications in Czech and Czechoslovak journals making reference to the condition after childhood. We present two cases of adult patients with HD. The first case is a 46-year-old male patient suffering from chronic constipation since childhood and diagnosed with megacolon at the age of 16; however, no further detailed diagnosis was done. At the age of 41, he developed a sigmoid perforation due to fecaloma and underwent urgent rectosigmoid resection and colostomy. 5 months later, Swensons coloanal anastomosis with diverting ileostomy was performed. Postoperative course was uneventful. He has two bowel movements a day. 7 years after the Swensons procedure, he also underwent adhesiolysis for acute bowel obstruction. His daughter was operated on due to HD at 16 days of age. The second case is a 57-year-old male patient. He suffered from chronic constipation and megacolon since 2 years of age and was diagnosed with congenital megacolon at the age of 19. However, no detailed diagnostics followed. He had a long interval between stools of up to 14 days. He underwent colonoscopy and, with a diagnosis of resistant Crohns disease, was referred to a surgical department where he was diagnosed with HD. Left hemicolectomy was first performed, followed by Swensons procedure with diverting ileostomy. All postoperative courses were uneventful. Currently he passes one or two soft stools a day. Adult HD is extremely rare. However, adult surgeons should consider it in case of refractory constipation since childhood associated with megacolon. Diagnosis is based on contrast radiography and rectal biopsy. Both Swensons and Duhamels procedures are suitable for surgical management. Left hemicolectomy with colonic rotation and coloanal anastomosis and/or proctocolectomy with J-pouch anastomosis are indicated in advanced forms of non-functional megacolon.Key words: adult Hirschsprungs disease - megacolon surgical therapy.

Bariatric surgery is the best method for treating obesity and its comorbidities. Our aim was to provide a detailed analysis of the perioperative outcomes in Mexican patients that underwent surgery at a high-volume hospital center. A retrospective study was conducted on all the patients that underwent bariatric surgery at a single hospital center within a time frame of 4 and one-half years. Demographics, the perioperative variables, complications (early and late), weight loss, failure, and type 2 diabetes mellitus remission were all analyzed. Five hundred patients were included in the study, 83.2% of whom were women. Mean patient age was 38.8 years and BMI was 44.1kg/m 2 . The most common comorbidities were high blood pressure, dyslipidemia, and diabetes. Laparoscopic gastric bypass surgery was performed in 85.8% of the patients, sleeve gastrectomy in 13%, and revision surgeries in 1%. There were 9.8% early complications and 12.2% late ones, with no deaths. Overall weight loss as the excess weight loss percentage at 12 and 24 months was 76.9 and 77.6%. The greatest weight loss at 12 months was seen in the patients that underwent laparoscopic gastric bypass. A total of 11.4% of the patients had treatment failure. In the patients with type 2 diabetes mellitus, 68.7% presented with complete disease remission and 9.3% with partial remission. There was improvement in 21.8% of the cases. In our experience at a high-volume hospital center, bariatric surgery is safe and effective, based on the low number of adverse effects and consequent weight loss and type 2 diabetes mellitus control. Long-term studies with a larger number of patients are needed to determine the final impact of those procedures. Copyright © 2018 Asociación Mexicana de Gastroenterología.

Medical ethics on film: towards a reconstruction of the teaching of healthcare professionals.

Volandes, Angelo

2007-11-01

The clinical vignette remains the standard means by which medical ethics are taught to students in the healthcare professions. Although written or verbal vignettes are useful as a pedagogic tool for teaching ethics and introducing students to real cases, they are limited, since students must imagine the clinical scenario. Medical ethics are almost universally taught during the early years of training, when students are unfamiliar with the clinical reality in which ethics issues arise. Film vignettes fill in that imaginative leap. By providing vivid details with images, film vignettes offer rich and textured details of cases, including the patient's perspective and the clinical reality. Film vignettes provide a detailed ethnography that allows for a more complete discussion of the ethical issues. Film can serve as an additional tool for teaching medical ethics to members of the healthcare professions.

As stereotactic body radiotherapy (SBRT) is a highly dose-dense radiotherapy, adverse events of neighboring normal tissues are a major concern. This study thus aimed to clarify the frequency and degree of clinical symptoms in patients with rib fractures after SBRT for primary lung cancer and to reveal risk factors for rib fracture. Appropriate α/β ratios for discriminating between fracture and non-fracture groups were also investigated. Between November 2001 and April 2009, 177 patients who had undergone SBRT were evaluated for clinical symptoms and underwent follow-up thin-section computed tomography (CT). The time of rib fracture appearance was also assessed. Cox proportional hazard modeling was performed to identify risk factors for rib fracture, using independent variables of age, sex, maximum tumor diameter, radiotherapeutic method and tumor-chest wall distance. Dosimetric details were analyzed for 26 patients with and 22 randomly-sampled patients without rib fracture. Biologically effective dose (BED) was calculated with a range of α/β ratios (1-10 Gy). Receiver operating characteristics analysis was used to define the most appropriate α/β ratio. Rib fracture was found on follow-up thin-section CT in 41 patients. The frequency of chest wall pain in patients with rib fracture was 34.1% (14/41), and was classified as Grade 1 or 2. Significant risk factors for rib fracture were smaller tumor-chest wall distance and female sex. Area under the curve was maximal for BED at an α/β ratio of 8 Gy. Rib fracture is frequently seen on CT after SBRT for lung cancer. Small tumor-chest wall distance and female sex are risk factors for rib fracture. However, clinical symptoms are infrequent and generally mild. When using BED analysis, an α/β ratio of 8 Gy appears most effective for discriminating between fracture and non-fracture patients.

Pulmonary sarcomatoid carcinoma (PSC) is an unusual form of non-small-cell lung cancer (NSCLC). Because of its rarity and heterogeneity, the treatment and prognosis of PSC have not been clearly described. We retrospectively evaluated all patients with a diagnosis of PSC from 1997 to 2015 at the Mayo Clinic (Rochester, MN). The clinical characteristics, treatment details, and outcomes were collected. The survival rates of the PSC patients were compared with those for other subtypes of NSCLC. We used propensity score matching to minimize the bias resulting from to imbalanced comparison groups. The study included 127 PSC patients. The median age at diagnosis was 68 years (range, 32-89 years), most of whom were men (61%) and smokers (82%). The clinical stage was I, II, III, and IV in 15.9%, 20.6%, 22.2%, and 41.3%, respectively. The median survival time was 9.9 months (95% confidence interval [CI], 7.6-12.6 months). The 1-, 2-, and 5-year survival rates were 42%, 23%, and 15%, respectively. Most patients received multimodality treatment. Of the 3 patients who received neoadjuvant chemotherapy, a partial response was demonstrated in 2. Twenty-five patients who underwent palliative chemotherapy were evaluated for tumor response: 52% experienced progression, 40% stable disease, 8.0% a partial response, and 0% a complete response. Multivariate analysis showed T stage, M stage, and treatment with surgery plus neoadjuvant chemotherapy or surgery plus adjuvant therapy were independent prognostic factors (P < .05). In matched analysis, multivariate models revealed worse overall survival for PSC compared with adenocarcinoma (hazard ratio, 2.38; 95% CI, 1.61-2.53) and squamous cell carcinoma (hazard ratio, 2.20; 95% CI, 1.44-2.34). We found the outcome of PSC to be significantly worse than that of adenocarcinoma and squamous cell carcinoma. Neoadjuvant or adjuvant chemotherapy, in addition to surgical resection, should be considered. Copyright © 2017 Elsevier Inc. All rights reserved.

The association between vitamin D and clinical parameters in obstructive lung diseases (OLDs), including COPD and bronchial asthma, was previously investigated. As asthma-COPD overlap syndrome (ACOS) is a new clinical entity, the prevalence of vitamin D levels in ACOS is unknown. Our aim was to assess the levels of circulating vitamin D (25-hydroxyvitamin D [25(OH)D]) in different OLDs, including ACOS patients, and its correlation with clinical parameters. A total of 106 men and women (control, n=21; asthma, n=44; COPD, n=21; and ACOS, n=20) were involved in the study. All patients underwent detailed clinical examinations; disease control and severity was assessed by disease-specific questionnaires (COPD assessment test, asthma control test, and modified Medical Research Council); furthermore, 25(OH)D levels were measured in all patients. The 25(OH)D level was significantly lower in ACOS and COPD groups compared to asthma group (16.86±1.79 ng/mL and 14.27±1.88 ng/mL vs 25.66±1.91 ng/mL). A positive correlation was found between 25(OH)D level and forced expiratory volume in 1 second (r=0.4433; P<0.0001), forced vital capacity (FVC) (r=0.3741; P=0.0004), forced expiratory flow between 25% and 75% of FVC (r=0.4179; P<0.0001), and peak expiratory flow (r=0.4846; P<0.0001) in OLD patient groups. Asthma control test total scores and the 25(OH)D level showed a positive correlation in the ACOS (r=0.4761; P=0.0339) but not in the asthma group. Higher COPD assessment test total scores correlated with decreased 25(OH)D in ACOS (r=-0.4446; P=0.0495); however, this was not observed in the COPD group. Vitamin D deficiency is present in ACOS patients and circulating 25(OH)D level may affect disease control and severity.

Purpose: To report the approach, technical success, clinical outcomes, complications, and follow-up of ethiodized oil intranodal lymphangiography with cyanoacrylate glue embolization for the treatment of lymphatic leak after robot-assisted laparoscopic pelvic resection. Materials and Methods: Four men with mean age 68.7 ± 14.3 years were treated with ethiodized oil intranodal lymphangiography with cyanoacrylate embolization for postoperative lymphatic leak. Patients underwent either (1) cystoprostatectomy with ileal conduit and bilateral extensive pelvic lymph node dissection for muscle-invasive urothelial carcinoma and presented with postoperative lymphatic ascites ( n  = 2) or (2) prostatectomy with bilateral standard pelvic lymph node dissection for prostate carcinoma and presented with postoperative pelvic lymphoceles ( n  = 2). Intranodal lymphangiography and embolization procedural details, technical success, clinical outcomes, and follow-up were recorded. Results: In four patients, a total of six ethiodized oil intranodal lymphangiograms were performed, two procedures being repeated interventions. Inguinal lymph node catheterization and ethiodized oil lymphangiography was technically effective in all procedures. A mean of 5.2 ± 2.0 mL of ethiodized oil was used for lymphatic opacification. Cyanoacrylate was diluted to 24.2% with ethiodized oil and 0.44 mL of cyanoacrylate was instilled during first time interventions. On repeat procedures, cyanoacrylate was diluted to 51.7%, and 0.52 mL was instilled. The primary clinical success rate was 50% ( n  = 2/4). Clinical success was achieved in all patients after two interventions ( n  = 4; 100%). No complications were reported at mean follow-up of 134.7 ± 79.2 days (range: 59-248 days). Conclusion: Ethiodized oil intranodal lymphangiography with direct cyanoacrylate glue embolization is a minimally invasive treatment option for lymphatic leak after pelvic resection.

To investigate the clinical application of spontaneous acrosome reaction (AR) rate of sperm in predicting the outcome of in-vitro fertilization and embryo transfer (IVF-ET). The spontaneous AR rate of the sperm of patients who underwent IVF-ET treatment in our center during the period from November to December 2014 were studied. The cut-off value from 6% to 12% were set and analyzed its association between the IVF-ET outcomes (including fertility rates, normal fertilization rates and high-quality embryo rates). For those who underwent fresh embryo transplantation, the rates of chemical pregnancy and clinical pregnancy were calculated, and compared the spontaneous AR rates and quantity of acrosomal enzyme according to the pregnancy outcome. There were 202 patients in this study and the mean spontaneous AR rate was 5.99%±5.18%. For patients with the spontaneous AR rate ≥9% versus <9%, the fertility rate, normal fertilization rate and high-quality embryo rate were 81.33% vs 83.85%, 60.53% vs 60.99%, and 51.10% vs 59.67%, respectively, with statistically significant difference in the high-quality embryo rate (P=0.02). For patients who underwent fresh embryo transplantation, when comparison was made between those with spontaneous AR rate ≥8% and those <8%, the rate of chemical pregnancy and clinical pregnancy were 48.57% (17/35) vs 69.64% (78/112) and 37.14% (13/35) vs 63.39% (71/112), respectively, both with statistically significant difference (P=0.02 and P<0.01). The patients with clinical pregnancy had lower spontaneous AR rate than those without clinical pregnancy (5.41%±3.87% vs 7.40%±6.79%, P=0.04), while the quantity of acrosomal enzyme showed no significant difference [(131.79±68.50) vs (153.62±59.59) μU/10(6,) P=0.06]. Logistic regression analysis demonstrated association between spontaneous AR rates and clinical pregnancy (OR=0.93, 95%CI: 0.87-0.99, P=0.03). The spontaneous AR rate of sperm may have clinical significance in predicting the outcome of IVF-ET, as it is reversely correlated with IVF high-quality embryo rate and pregnancy rate. The quantity of acrosomal enzyme may not have significant predictive value for the outcome of IVF.

The aim of this study was to analyze the features of incidentally detected prostate cancer (PCa) in radical cystoprostatectomy (RCP) specimens to determine their pathological characteristics and clinical significance. In this retrospective study, we reviewed the clinical and pathological records of 431 consecutive patients with muscle-invasive bladder cancer who underwent RCP at Hirosaki University. Of these, we focused on 237 male patients with prostate-specific antigen (PSA) measurements and digital rectal examinations (DRE) that were recorded prior to the RCP. Significant PCa was defined as a tumor with a Gleason 4 or 5 pattern, pathological T3 or higher stage, lymph node involvement or three or more multifocal lesions within the prostate specimen. We compared clinically significant and insignificant PCa. In this study, a total of 43 patients (18.1%) were diagnosed with incidental PCa via RCP specimens. Age, preoperative PSA levels and pathological T stage in patients with clinically significant PCa were considerably higher than in those with insignificant cancer. Apical involvement was found in 16 patients, including 11 of those with clinically significant PCa. By the end of the follow-up period, none of the enrolled patients had a biochemical recurrence after surgery or died from PCa. According to our findings, preoperative risk factors were not reliable enough to accurately predict clinically significant PCa. Although there was no biochemical relapse or clinical recurrence of PCa in this study, the potential oncologic risk of prostate-sparing RCP must be considered. © The Author 2017.

Quality of referral: What information should be included in a request for diagnostic imaging when a patient is referred to a clinical radiologist?

PubMed

G Pitman, Alexander

2017-06-01

Referral to a clinical radiologist is the prime means of communication between the referrer and the radiologist. Current Australian and New Zealand government regulations do not prescribe what clinical information should be included in a referral. This work presents a qualitative compilation of clinical radiologist opinion, relevant professional recommendations, governmental regulatory positions and prior work on diagnostic error to synthesise recommendations on what clinical information should be included in a referral. Recommended requirements on what clinical information should be included in a referral to a clinical radiologist are as follows: an unambiguous referral; identity of the patient; identity of the referrer; and sufficient clinical detail to justify performance of the diagnostic imaging examination and to confirm appropriate choice of the examination and modality. Recommended guideline on the content of clinical detail clarifies when the information provided in a referral meets these requirements. High-quality information provided in a referral allows the clinical radiologist to ensure that exposure of patients to medical radiation is justified. It also minimises the incidence of perceptual and interpretational diagnostic error. Recommended requirements and guideline on the clinical detail to be provided in a referral to a clinical radiologist have been formulated for professional debate and adoption. © 2017 The Royal Australian and New Zealand College of Radiologists.

The use of histological degeneration scores in surgically-treated herniated lumbar discs is not common in clinical practice and its use has been primarily restricted to research. The objective of this study is to evaluate if there is an association between a higher grade of histological degeneration when compared with clinical or radiological parameters. Retrospective consecutive analysis of 122 patients who underwent single-segment lumbar disc herniation surgery. Clinical information was available on all patients, while the histological study and preoperative magnetic resonance imaging were also retrieved for 75 patients. Clinical variables included age, duration of symptoms, neurological deficits, or affected deep tendon reflex. The preoperative magnetic resonance imaging was evaluated using Modic and Pfirrmann scores for the affected segment by 2 independent observers. Histological degeneration was evaluated using Weiler's score; the presence of inflammatory infiltrates and neovascularization, not included in the score, were also studied. Correlation and chi-square tests were used to assess the association between histological variables and clinical or radiological variables. Interobserver agreement was also evaluated for the MRI variables using weighted kappa. No statistically significant correlation was found between histological variables (histological degeneration score, inflammatory infiltrates or neovascularization) and clinical or radiological variables. Interobserver agreement for radiological scores resulted in a kappa of 0.79 for the Pfirrmann scale and 0.65 for the Modic scale, both statistically significant. In our series of patients, we could not demonstrate any correlation between the degree of histological degeneration or the presence of inflammatory infiltrates when compared with radiological degeneration scales or clinical variables such as the patient's age or duration of symptoms.

This study was designed to examine the natural history of subclinical leaks and their effect on bowel function and quality of life and to evaluate water-soluble contrast enema features that predict anastomotic healing after leaks. Consecutive patients who underwent low rectal anastomosis were followed up postoperatively for leaks. All leaks were confirmed radiologically with CT scanning and water-soluble contrast enema imaging. Water-soluble contrast enemas were serially repeated to identify healing. Characteristics on initial water-soluble contrast enema were correlated with observed healing. Postoperatively, patients were required to fill in a quality of life and a bowel function questionnaire. A total of 138 patients underwent low rectal anastomosis procedures with a median follow-up period of 26 (interquartile range, 19-37) months. There were 23 documented leaks of which 13 (9 percent) presented clinically and 10 (8 percent) presented subclinically. Ileostomy closure was possible in 4 of 13 (30 percent) patients with a clinical leak and all 10 (100 percent) patients with a subclinical leak. Median quality of life scores were lower for patients with clinical leaks and no ileostomy closure (P = 0.03). Bowel function for subclinical leak patients and clinical leak patients with ileostomy closure were similarly impaired. The presence of a cavity (P = 0.01) and a stricture (P = 0.01) at the anastomotic site were unfavorable radiologic features associated with nonhealing. Subclinical leaks are more benign in their natural history compared with clinical leaks. Quality of life and bowel function is no better in patients with a subclinical leak compared with patients with a clinical leak who have ileostomy closure. Anastomotic leaks may resolve if favorable radiologic features are present.

MRI predictors of clinical success in MR-guided focused ultrasound (MRgFUS) treatments of uterine fibroids: results from a single centre.

To assess the technical and clinical results of MRgFUS treatment and factors affecting clinical treatment success. A total of 252 women (mean age, 42.1 ± 6.9 years) with uterine fibroids underwent MRgFUS. All patients underwent MRI before treatment. Results were evaluated with respect to post-treatment nonperfused volume (NPV), symptom severity score (SSS), reintervention rate, pregnancy and safety data. NPV ratio was significantly higher in fibroids characterized by low signal intensity in contrast-enhanced T1-weighted fat saturated MR images and in fibroids distant from the spine (>3 cm). NPV ratio was lower in fibroids with septations, with subserosal component and in skin-distant fibroids (p < 0.001). NPV ratio was highly correlated with clinical success: NPV of more than 80 % resulted in clinical success in more than 80 % of patients. Reintervention rate was 12.7 % (mean follow-up time, 19.4 ± 8 months; range, 3-38). Expulsion of fibroids (21 %) was significantly correlated with a high clinical success rate. No severe adverse events were reported. Adequate patient selection and correct treatment techniques, based on the learning curve of this technology, combined with technical advances of the system, lead to higher clinical success rates with low complications rate, comparable to other uterine-sparing treatment options. • MRgFUS appears to be a valid alternative to other uterus-preserving therapies • Patient selection is a significant factor in achieving high NPV ratios • MRI screening parameters correlate with the amount of fibroid ablation in MRgFUS • NPV results of more than 80 % correlate with higher clinical success rates.

To determine the incidence of malignancy for radial scars (RS)/radial sclerosing lesions (RSL) without associated atypia or malignancy identified at needle biopsy. Retrospective review of the pathology data base from January 2004 to July 2013 yielded 100 needle biopsies diagnosed as RS/RSL without associated atypia/malignancy. The RS/RSL was considered "incidental" if the target was calcifications and "targeted" if imaging revealed a mass, architectural distortion, or suspicious magnetic resonance imaging enhancement. The electronic medical record was used to identify surgical pathology, follow-up imaging, and clinical course; all pathology slides and imaging were reviewed by a board-certified pathologist and radiologist, respectively. Patient age, laterality, RS/RSL size, microcalcifications, and associated benign lesions were recorded. Among 100 cases, 54 were "incidental" and 46 were "targeted." In the incidental group, 14 underwent excision, 30 had imaging follow-up, and 10 were lost to follow-up. In the targeted group, 27 underwent excision, 11 had imaging follow-up, and 8 were lost to follow-up. Atypia was identified in four excisions: three from the incidental group and one from the targeted group. Among these, three had negative imaging follow-up (mean 45 months; range 15-60 months); the fourth patient (one of the incidental group) underwent excision alone. One of the 27 "targeted" patients who underwent excision developed ductal carcinoma in situ of the contralateral breast at 96 months. There have been no ipsilateral malignancies. We found no evidence of associated malignancy at excision for either incidental or targeted biopsies of RS/RSL without atypia. Our study suggests that close imaging follow-up is adequate for patients with RS/RSL without associated atypia/malignancy on needle biopsy. © 2016 Wiley Periodicals, Inc.

OBJECT Currently, bilateral procedures involve 2 sequential implants in each of the hemispheres. The present report demonstrates the feasibility of simultaneous bilateral procedures during the implantation of deep brain stimulation (DBS) leads. METHODS Fifty-seven patients with movement disorders underwent bilateral DBS implantation in the same study period. The authors compared the time required for the surgical implantation of deep brain electrodes in 2 randomly assigned groups. One group of 28 patients underwent traditional sequential electrode implantation, and the other 29 patients underwent simultaneous bilateral implantation. Clinical outcomes of the patients with Parkinson's disease (PD) who had undergone DBS implantation of the subthalamic nucleus using either of the 2 techniques were compared. RESULTS Overall, a reduction of 38.51% in total operating time for the simultaneous bilateral group (136.4 ± 20.93 minutes) as compared with that for the traditional consecutive approach (220.3 ± 27.58 minutes) was observed. Regarding clinical outcomes in the PD patients who underwent subthalamic nucleus DBS implantation, comparing the preoperative off-medication condition with the off-medication/on-stimulation condition 1 year after the surgery in both procedure groups, there was a mean 47.8% ± 9.5% improvement in the Unified Parkinson's Disease Rating Scale Part III (UPDRS-III) score in the simultaneous group, while the sequential group experienced 47.5% ± 15.8% improvement (p = 0.96). Moreover, a marked reduction in the levodopa-equivalent dose from preoperatively to postoperatively was similar in these 2 groups. The simultaneous bilateral procedure presented major advantages over the traditional sequential approach, with a shorter total operating time. CONCLUSIONS A simultaneous stereotactic approach significantly reduces the operation time in bilateral DBS procedures, resulting in decreased microrecording time, contributing to the optimization of functional stereotactic procedures.

Conversion therapy is an option for unresectable metastatic gastric cancer when distant metastases are controlled by chemotherapy; however, the feasibility and efficacy remain unclear. This study aimed to assess the feasibility and efficacy of conversion therapy in patients with initially unresectable gastric cancer treated with docetaxel, cisplatin, and S-1 (DCS) chemotherapy by evaluating clinical outcomes. One hundred unresectable metastatic gastric cancer patients, enrolled in three DCS chemotherapy clinical trials, were retrospectively evaluated. The patients received oral S-1 (40 mg/m 2 b.i.d.) on days 1-14 and intravenous cisplatin (60 mg/m 2 ) and docetaxel (50-60 mg/m 2 ) on day 8 every 3 weeks. Conversion therapy was defined when the patients could undergo R0 resection post-DCS chemotherapy and were able to tolerate curative surgery. Conversion therapy was achieved in 33/100 patients, with no perioperative mortality. Twenty-eight of the 33 patients (84.8 %) achieved R0 resection, and 78.8 % were defined as histological chemotherapeutic responders. The median overall survival (OS) of patients who underwent conversion therapy was 47.8 months (95 % CI 28.0-88.5 months). Patients who underwent R0 resection had significantly longer OS than those who underwent R1 and R2 resections (P = 0.0002). Of the patients with primarily unresectable metastases, 10 % lived >5 years. Among patients who underwent conversion therapy, multivariate analysis showed that the pathological response was a significant independent predictor for OS. DCS safely induced a high conversion rate, with very high R0 and pathological response rates, and was associated with a good prognosis; these findings warrant further prospective investigations.

Background The aim of this study was to review a series of consecutive percutaneous cholecystostomies (PC) to analyse the clinical outcomes. Methods All patients who underwent a PC between 2000 and 2010 were reviewed retrospectively for indications, complications, and short- and long-term outcomes. Results Fifty-three patients underwent a PC with a median age was 74 years (range 14–93). 92.4% (n = 49) of patients were American Society of Anesthesiologists (ASA) III and IV. 82% (43/53) had ultrasound-guided drainage whereas 18% (10/53) had computed tomography (CT)-guided drainage. 71.6% (n = 38) of PC's employed a transhepatic route and 28.4% (n = 15) transabdominal route. 13% (7/53) of patients developed complications including bile leaks (n = 5), haemorrhage (n = 1) and a duodenal fistula (n = 1). All bile leaks were noted with transabdominal access (5 versus 0, P = 0.001). 18/53 of patients underwent a cholecystectomy of 4/18 was done on the index admission. 6/18 cholecystectomies (33%) underwent a laparoscopic cholecystectomy and the remaining required conversion to an open cholecystectomy (67%). 13/53 (22%) patients were readmitted with recurrent cholecystitis during follow-up of which 7 (54%) had a repeated PC. 12/53 patients died on the index admission. The overall 1-year mortality was 37.7% (20/53). Conclusions Only a small fraction of patients undergoing a PC proceed to a cholecystectomy with a high risk of conversion to an open procedure. A quarter of patients presented with recurrent cholecystitis during follow-up. The mortality rate is high during the index admission from sepsis and within the 1 year of follow-up from other causes.

In a randomized trial, pasireotide significantly decreased the incidence and severity of postoperative pancreatic fistula (POPF). Subsequent analyses concluded that its routine use is cost-effective. We hypothesized that selective administration of the drug to patients at high risk for POPF would be more cost-effective. Consecutive patients who did not receive pasireotide and underwent pancreatoduodenectomy (PD) or distal pancreatectomy (DP) between July 2011 and January 2014 were distributed into groups based on their risk of POPF using a multivariate recursive partitioning regression tree analysis (RPA) of preoperative clinical factors. The costs of treating hypothetical patients in each risk group were then computed based upon actual institutional hospital costs and previously published relative risk values associated with pasireotide. Among 315 patients who underwent pancreatectomy, grade B/C POPF occurred in 64 (20%). RPA allocated patients who underwent PD into four groups with a risk for grade B/C POPF of 0, 10, 29, or 60% (P < 0.001) on the basis of diagnosis, pancreatic duct diameter, and body mass index. Patients who underwent DP were allocated to three groups with a grade B/C POPF risk of 14, 26, or 44% (P = 0.05) on the basis of pancreatic duct diameter alone. Although the routine administration of pasireotide to all 315 patients would have theoretically saved $30,892 over standard care, restriction of pasireotide to only patients at high risk for POPF would have led to a cost savings of $831,916. Preoperative clinical characteristics can be used to characterize patients' risk for POPF following pancreatectomy. Selective administration of pasireotide only to patients at high risk for grade B/C POPF may maximize the cost-efficacy of prophylactic pasireotide.

Is nonoperative management of partial distal biceps tears really successful?

Bauer, Tyler M; Wong, Justin C; Lazarus, Mark D

The current treatment of partial distal biceps tears is a period of nonoperative management, followed by surgery, if symptoms persist. Little is known about the success rate and outcomes of nonoperative management of this illness. We identified 132 patients with partial distal biceps tears through an International Classification of Diseases, Ninth Revision code query of our institution's database. Patient records were reviewed to abstract demographic information and confirm partial tears of the distal biceps tendon based on clinical examination findings and confirmatory magnetic resonance imaging (MRI). Seventy-four patients completed an outcome survey. In our study, 55.7% of the contacted patients who tried a nonoperative course (34 of 61 patients) ultimately underwent surgery, and 13 patients underwent immediate surgery. High-need patients, as defined by occupation, were more likely to report that they recovered ideally if they underwent surgery, as compared with those who did not undergo surgery (odds ratio, 11.58; P = .0138). For low-need patients, the same analysis was not statistically significant (P = .139). There was no difference in satisfaction scores between patients who tried a nonoperative course before surgery and those who underwent immediate surgery (P = .854). An MRI-diagnosed tear of greater than 50% was a predictor of needing surgery (odds ratio, 3.0; P = .006). This study has identified clinically relevant information for the treatment of partial distal biceps tears, including the following: the failure rate of nonoperative treatment, the establishment of MRI percent tear as a predictor of failing nonoperative management, the benefit of surgery for the high-need occupational group, and the finding that nonoperative management does not negatively affect outcome if subsequent surgery is necessary.

Hypersensitivity to acetylsalicylic acid (ASA) constitutes a serious problem for subjects with coronary artery disease. In such subjects, physicians have to choose the more appropriate procedure between challenge and desensitization. As the literature on this issue is sparse, this study aimed to establish in these subjects clinical criteria for eligibility for an ASA challenge and/or desensitization. Collection and analysis of data on ASA challenges and desensitizations from 10 allergy centers, as well as consensus among the related physicians and an expert panel. Altogether, 310 subjects were assessed; 217 had histories of urticaria/angioedema, 50 of anaphylaxis, 26 of nonimmediate cutaneous eruptions, and 17 of bronchospasm related to ASA/nonsteroidal anti-inflammatory drugs (NSAID) intake. Specifically, 119 subjects had index reactions to ASA doses lower than 300 mg. Of the 310 subjects, 138 had an acute coronary syndrome (ACS), 101 of whom underwent desensitizations, whereas 172 suffered from a chronic ischemic heart disease (CIHD), 126 of whom underwent challenges. Overall, 163 subjects underwent challenges and 147 subjects underwent desensitizations; 86 of the latter had index reactions to ASA doses of 300 mg or less. Ten subjects reacted to challenges, seven at doses up to 500 mg, three at a cumulative dose of 110 mg. The desensitization failure rate was 1.4%. In patients with stable CIHD and histories of nonsevere hypersensitivity reactions to ASA/NSAIDs, an ASA challenge is advisable. Patients with an ACS and histories of hypersensitivity reactions to ASA, especially following doses lower than 100 mg, should directly undergo desensitization. © 2016 John Wiley & Sons A/S.

Morgan, Katherine A; Fontenot, Bennett B; Harvey, Norman R; Adams, David B

Background: Because survival after pancreaticoduodenectomy for cancer is limited, it is difficult to assess longterm pancreaticojejunal anastomotic patency. However, in patients with benign disease, pancreaticojejunal anastomotic stenosis may become problematic. What happens when pancreaticojejunal anastomosis revision is undertaken? Methods: Patients undergoing pancreatic anastomotic revision after pancreatic head resection for benign disease between 1997 and 2007 at the Medical University of South Carolina were identified. A retrospective chart review and analysis were undertaken with the approval of the Institutional Review Board for the Evaluation of Human Subjects. Longterm follow-up was obtained by patient survey at a clinic visit or by telephone. Results: During the study period, 237 patients underwent pancreatic head resection. Of these, 27 patients (17 women; median age 42 years) underwent revision of pancreaticojejunal anastomosis. Six patients (22%) had a pancreatic leak or abscess at the time of the index pancreatic head resection. The indication for revision of anastomosis was intractable pain. All patients underwent preoperative magnetic resonance cholangiopancreatography (MRCP), which indicated anastomotic stricture in 18 patients (63%). Nine other patients underwent exploration based on clinical suspicion caused by recurrent pancreatitis and stenosis was confirmed at the time of surgery. Six patients (22%) had perioperative complications after revision. The median length of stay was 12 days. There were no perioperative deaths; however, late mortality occurred in four patients (15%). Six of 23 survivors (26%) at the time of follow-up (median 56 months) reported longterm pain relief. Conclusions: Stricture of the pancreaticojejunal anastomosis after pancreatic head resection presents with recurrent pancreatitis and pancreatic pain. MRCP has good specificity in the diagnosis of anastomotic obstruction, but lacks sensitivity. Pancreaticojejunal revision is safe, but rarely effective, as a means of pain relief in patients with the pain syndrome associated with chronic pancreatitis. PMID:20590889

Wide resection of the ureteral orifice (UO) may result in scarring and stenosis of the ureterovesical junction (UVJ). We aimed to describe a technique of endoscopic spatulation of the intramural ureter in patients undergoing resection of the UO at the time of transurethral resection of bladder tumor (TURBT) and compare the surgical and oncological outcomes of this procedure with those of patients undergoing conventional UO resection. The clinical records of patients who underwent TURBT at a single institution were retrospectively analyzed. Patients who underwent conventional UO resection or UO resection followed by endoscopic spatulation of the intramural ureter were included in the analysis. The two groups were compared in terms of intra- and postoperative outcomes. A total of 227 patients were included in the final comparative analyses. Of them, 104 underwent conventional UO resection and 123 underwent UO resection followed by endoscopic spatulation of the intramural ureter. The two groups were comparable for demographic and clinical features. There were not statistically significant differences in terms of mean operative times. The incidence of transient postoperative hydronephrosis as well as UVJ scarring and stenosis was significantly lower in patients undergoing endoscopic spatulation of the intramural ureter. The two groups were similar in terms of incidence of vesicoureteral reflux (VUR) and upper urinary tract cancer recurrence. Endoscopic spatulation of the intramural ureter after UO resection is a safe and quick procedure that significantly reduces the incidence of transient early postoperative hydronephrosis and late UVJ stricture if compared with UO resection alone. This procedure is quick to perform, safe, and does not increase the risk of VUR.

We report a case of a 35-year-old woman who underwent uterine artery embolization (UAE) for symptomatic multiple uterine fibroids with collateral aberrant right ovarian artery that originated from the right external iliac artery. We believe that this is the first reported case in the literature of this collateral uterine flow by the right ovarian artery originated from the right external iliac artery. We briefly present the details of the case and review the literature on variations of ovarian artery origin that might be encountered during UAE.

[Somatic treatments in psychiatry: A descriptive study of laboratory tests and systematic involvement in terms of overall care].

Somatic suffering concerns mental health in many ways, but numerous psychiatrists are still reluctant to take an interest in somatic care due to a supposed lack of expertise and an alteration of the psychotherapeutic link, whilst in parallel numerous fellow physicians are quite apprehensive about treating patients with mental disorders. We have undertaken a targeted clinical audit regarding the somatic treatment of in-patients in a psychiatric unit to propose the implementation of measures of improvement. Our study focused on the identification and treatment of abnormal liver function tests, a subject that has been overlooked in the literature, yet from clinical experience the results are often abnormal in psychiatric unit in-patients. We analysed retrospectively over a period of two years the medical records of psychiatric unit in-patients with abnormal results for at least one of the following hepatic markers: aspartate-aminotransferase (AST), alanine transaminase (ALT), gamma-glutamyltransferase (GGT), alkaline phosphatase (ALP) and bilirubin. In total, 188 liver test results were abnormal, with an average of 1.7 per patient. The abnormal test results were in decreasing order: elevation in GGT (80 % of patients), elevation in transaminases (65.5 % for each), elevation in ALP (19.1 %) and elevation in bilirubin (7.27 %). Abnormal transaminase levels were lower than 10N, with a peak between 1N and 3N for ALT and a peak between 1N and 5N for AST. The elevation in GGT was between 1N and 34N, although 71.6 % of these values were below 5N. ALP was below 3N. The medical history was traced in 93.6 % of the records. A somatic clinical examination was only reported in 39 records (35.5 %) and was carried out by a hepato-gastroenterologist (HGE) in 30.8 % of cases, the establishment's emergency physician in 25.7 % of cases and the psychiatrists in 12.9 % of cases. Patients with abnormal liver function test results frequently underwent other biological and morphological examinations. A discharge letter was found in almost all cases. Abnormal liver function test results were indicated in less than 45 % of these discharge letters, whilst over half reported the establishment of a future treatment coordinated by the GP, in close collaboration with the gastroenterologist in at least half the cases. Our study was carried out in an open psychiatric unit in the heart of a general hospital that mainly receives patients suffering from thymus and anxiety disorders, addictive disorders, somatoform disorders, personality disorders and psycho-organic disorders. Patients suffering from schizophrenia or schizoaffective disorders comprised less than 10 % of admissions. Our retrospective study of over 750 hospital admissions over a period of two years found only 62.93 % of patients underwent liver function tests, which proved to be pathological in nearly 30 % of cases. Following a well-defined anamnesis, just over a third of patients underwent a physical examination whilst in hospital, more often a while after admission and not in the psychiatric unit. The consultation of fellow hospital physicians was limited even if the gastroenterologist was called upon in 30 % of cases. It was sometimes the treatment pathway or the fortuitous presence of co-morbidities that enabled the anaesthetist or emergency physician to carry out this clinical examination. However, when this physical examination was scheduled, clinical hepatobiliary signs were discovered in 30 % of patients. An accurate, formalised reference database detailing the principles of the somatic treatment of psychiatric unit in-patients should be established. Our results indicate the necessity of a referring physician in each psychiatric department. Copyright © 2016 L'Encéphale, Paris. Published by Elsevier Masson SAS. All rights reserved.

To identify the variability of short- and long-term survival outcomes among closed Phase III randomized controlled trials with small sample sizes comparing SBRT (stereotactic body radiation therapy) and surgical resection in operable clinical Stage I non-small cell lung cancer (NSCLC) patients. Clinical Stage I NSCLC patients who underwent surgery at our institution meeting the inclusion/exclusion criteria for STARS (Randomized Study to Compare CyberKnife to Surgical Resection in Stage I Non-small Cell Lung Cancer), ROSEL (Trial of Either Surgery or Stereotactic Radiotherapy for Early Stage (IA) Lung Cancer), or both were identified. Bootstrapping analysis provided 10,000 iterations to depict 30-day mortality and three-year overall survival (OS) in cohorts of 16 patients (to simulate the STARS surgical arm), 27 patients (to simulate the pooled surgical arms of STARS and ROSEL), and 515 (to simulate the goal accrual for the surgical arm of STARS). From 2000 to 2012, 749/873 (86%) of clinical Stage I NSCLC patients who underwent resection were eligible for STARS only, ROSEL only, or both studies. When patients eligible for STARS only were repeatedly sampled with a cohort size of 16, the 3-year OS rates ranged from 27 to 100%, and 30-day mortality varied from 0 to 25%. When patients eligible for ROSEL or for both STARS and ROSEL underwent bootstrapping with n=27, the 3-year OS ranged from 46 to 100%, while 30-day mortality varied from 0 to 15%. Finally, when patients eligible for STARS were repeatedly sampled in groups of 515, 3-year OS narrowed to 70-85%, with 30-day mortality varying from 0 to 4%. Short- and long-term survival outcomes from trials with small sample sizes are extremely variable and unreliable for extrapolation. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Breast cancer is one of the most common cancers and causes of death in females in Tajikistan; yet less than half of the adult women in Tajikistan have heard of breast cancer. Limited access to health care contributes to late stage presentation. We developed a public-private partnership to implement a breast cancer awareness intervention in a low-resource community in Khorog, Tajikistan. We trained local health professionals in clinical breast care and conducted a breast cancer screening and treatment program. The partnership involved visiting USA-based health professionals working alongside local health care providers (HCP) in the continuum of breast care-from education to the diagnostic evaluation and management of detected breast abnormalities. Patient data were collected using a web-based program (VirtualDoc). Twenty-four HCP received didactic and clinical breast examination training. 441 women underwent clinical breast evaluation. 74 (17%) had abnormal exams and underwent additional diagnostic procedures. We identified six (1.4%) cases of breast cancer (all locally advanced) and two women had benign fibroadenomas. All women with cancer underwent modified radical mastectomy, while the fibroadenomas were treated by cosmetically appropriate lumpectomy. Five of six subjects with cancer were previously aware of their breast lump and three had recently seen a family medicine (FM) doctor. Health systems assessment revealed availability of diagnostic equipment but lack of well-trained operators and clinician interpreters. We were successful in integrating clinical breast exams into the routine care of female patients by local FM doctors and in the process, achieved a better understanding of existing risk factors and barriers to breast cancer care. This public-private partnership, leveraging the technical expertise of visiting health professionals, demonstrates how a focused onsite training and awareness program can provide sustained improvements in breast care in a low-resource environment. © 2016 Wiley Periodicals, Inc.

To explore the clinical features and surgical treatment of tumors associated with Castleman's disease (CD). The clinical profiles of 19 patients with neck giant lymph node hyperplasia were analyzed retrospectively. There were 8 males and 11 females with a median age of 40 years old (range: 7 - 74). The tumor locations were neck (n = 12), neck & mediastinal cavity (n = 2), axillary fossa (n = 2), retroperitoneal area (n = 2) and abdominal cavity (n = 1). Eighteen of them underwent surgical resection of tumor or lymph nodes. All were diagnosed as CD by pathological examinations. There were 16 localized CD (LCD) including hyaline vascular type (HV type, n = 11), mixed type (mix type, n = 4) and plasma cell type-Hodgkin's disease (n = 1). Among 3 multicentric CD (MCD), there were 2 case of plasma cell type (PC type) and 1 case of mixed type (mix type). Long-term survival was achieved in 19 cases among which 1 case of plasma cell type MCD survived for 5 years and underwent a second operation and postoperative chemotherapy of CVP (cyclophosphamide, vincristine & prednisone) regimen for 3 cycles due to recurrence in 2 years and 1 case of plasma cell type LCD-Hodgkin's disease survived for 15 months and underwent a second operation and postoperative chemotherapy of ABVD (adriamycin, bleomycin, vinblastine & dacarbazine)regimen for 6 cycles due to recurrence in 6 months. One case of plasma cell type MCD in abdominal cavity on chemotherapy of CHOP (cyclophosphamide, hydroxydaunorubicin, vincristine & prednisone) regimen for 6 cycles was discharged after a successful management of intestinal obstruction. The major clinical symptom of CD is a gradually enlarging painless mass. Surgical resection of tumor remains the first-line treatment for localized CD and the prognosis is excellent. Multicentric and plasma cell type CDs are prone to recurrence and transformation to lymphoma. And their first-line therapeutic should encompass multi-modality regimens of surgery and adjuvant chemotherapy. However, the clinical prognosis is still poor.

Condylar reconstruction and replacement using alloplastic materials currently attracts much surgical interest. The major challenge is to functionally reconstruct the anatomical region; this is crucial in terms of correct mandibular function. The goal of the present study was to evaluate the clinical outcomes of and complications experienced by a series of oncological patients who underwent computer-aided design/computer-aided manufacturing (CAD/CAM) condylar reconstruction following resection-disarticulation of the mandible. We included nine patients who underwent disarticulation resection surgery to treat benign and malignant mandibular tumors involving the condylar region. All resections preserved the articular meniscus and featured placement of a CAD/CAM reconstructive plate supporting a fibular, microvascular free flap. The head of the prosthetic condyle reproduced the anatomical morphology of the native condyle. Patients were clinically evaluated in terms of occlusion stability, mandibular functional recovery, static and dynamic pain, and preservation of the normal mandibular contour. Planning and postoperative computed tomography (CT) scans were superimposed to assess the accuracy of reconstruction. No patient experienced plate exposure and, on direct clinical examination, no patient complained of joint pain. No patient developed plate loosening. No resorption of the glenoid fossa was evident when pre- and postoperative bone thicknesses were compared by CT. Preoperative occlusion was preserved in all dentate patients. One patient exhibited condylar displacement. In terms of reconstructive accuracy, the average postoperative deviation of the condyle from the preoperative position was 3.8 mm (range: 1.3-6.7 mm). The clinical outcomes of our series of oncological patients who underwent reconstruction using CAD/CAM plates including condyles were encouraging. The utility of our protocol needs to be confirmed in larger patient series. Copyright © 2016 European Association for Cranio-Maxillo-Facial Surgery. Published by Elsevier Ltd. All rights reserved.

Medical ethics on film: towards a reconstruction of the teaching of healthcare professionals

PubMed Central

Volandes, Angelo

2007-01-01

The clinical vignette remains the standard means by which medical ethics are taught to students in the healthcare professions. Although written or verbal vignettes are useful as a pedagogic tool for teaching ethics and introducing students to real cases, they are limited, since students must imagine the clinical scenario. Medical ethics are almost universally taught during the early years of training, when students are unfamiliar with the clinical reality in which ethics issues arise. Film vignettes fill in that imaginative leap. By providing vivid details with images, film vignettes offer rich and textured details of cases, including the patient's perspective and the clinical reality. Film vignettes provide a detailed ethnography that allows for a more complete discussion of the ethical issues. Film can serve as an additional tool for teaching medical ethics to members of the healthcare professions. PMID:17971475

Whereas advances in minimally invasive surgery have made laparoscopic staging technically feasible in stage I epithelial ovarian cancer, the practice remains controversial because of an absence of randomized trials and lack of high-quality observational studies demonstrating equivalent outcomes. This study seeks to evaluate the association of laparoscopic staging with survival among women with clinical stage I epithelial ovarian cancer. We used the National Cancer Data Base to identify all women who underwent surgical staging for clinical stage I epithelial ovarian cancer diagnosed from 2010 through 2012. The exposure of interest was planned surgical approach (laparoscopy vs laparotomy), and the primary outcome was overall survival. The primary analysis was based on an intention to treat: all women whose procedures were initiated laparoscopically were categorized as having had a planned laparoscopic procedure, regardless of subsequent conversion to laparotomy. We used propensity methods to match patients who underwent planned laparoscopic staging with similar patients who underwent planned laparotomy based on observed characteristics. We compared survival among the matched cohorts using the Kaplan-Meier method and Cox regression. We compared the extent of lymphadenectomy using the Wilcoxon rank-sum test. Among 4798 eligible patients, 1112 (23.2%) underwent procedures that were initiated laparoscopically, of which 190 (17%) were converted to laparotomy. Women who underwent planned laparoscopy were more frequently white, privately insured, from wealthier ZIP codes, received care in community cancer centers, and had smaller tumors that were more frequently of serous and less often of mucinous histology than those who underwent staging via planned laparotomy. After propensity score matching, time to death did not differ between patients undergoing planned laparoscopic vs open staging (hazard ratio, 0.77, 95% confidence interval, 0.54-1.09; P = .13). Planned laparoscopic staging was associated with a slightly higher median lymph node count (14 vs 12, P = .005). Planned laparoscopic staging was not associated with time to death after adjustment for receipt of adjuvant chemotherapy, histological type and grade, and pathological stage (hazard ratio, 0.82, 95% confidence interval, 0.57-1.16). Surgical staging via planned laparoscopy vs laparotomy was not associated with worse survival in women with apparent stage I epithelial ovarian cancer. Copyright © 2016 Elsevier Inc.

Due to the extreme rarity of primary intrapulmonary solitary fibrous tumours (SFTs), their clinical course, imaging characteristics, diagnosis, treatment and prognosis are poorly understood. The present study therefore assessed the diagnosis and management of primary intrapulmonary SFTs and systematically reviewed previously reported cases in the literature. A total of 5 patients who underwent resection for primary intrapulmonary SFTs were enrolled in the present study and their clinical course, tumour characteristics, management and survival were assessed in this retrospective study. Relevant studies regarding primary intrapulmonary SFTs were searched using PubMed and tumour characteristics, clinicopathologic features, therapeutic strategy and survival outcomes were reviewed. Of the 5 cases, all were males, with a mean age of 57.6 years (range, 37–68 years). All patients were asymptomatic and were identified incidentally on routine computed tomography examination. A total of 3 patients underwent thoracotomy and 2 patients underwent video-assisted thoracoscopic surgery. All tumours were completely resected. Postoperative haemorrhage occurred in 1 patient and he received surgical intervention for haemostasis. The average hospital stay was 15 (4–22) days, and no mortality occurred. The mean length of the postoperative follow-up was 37.6 (1–67) months. One patient was lost to follow-up, and 4 patients were asymptomatic. A total of 19 studies were identified from database searches. They included a total of 45 patients: Twenty-three males and 22 females (mean age, 59.4 years; range, 7–81 years). A total of 12 patients were asymptomatic, and pain and coughing were the major symptoms. Five, one, two, four, and 17 tumours occurred in the right upper lobe, right middle lobe, right lower lobe, left upper lobe and left lower lobe, respectively. A total of 39 patients underwent surgery, 1 patient underwent radiotherapy, and 1 patient underwent radiofrequency ablation. A total of 22 patients were followed up and the mean length of the postoperative follow-up was 48 (1–168) months. One patient was diagnosed with chest wall metastases, and 5 patients succumbed to mortality. To conclude, primary intrapulmonary SFTs are extremely rare and typically identified incidentally. The present findings indicated that the left lower lobe was the most common site location and complete surgical resection is a safe and effective treatment. PMID:29467886

Femoroacetabular impingement (FAI) is a common debilitating condition that is associated with groin pain and limitation in young and active patients. Besides FAI, various disorders such as hernias, adductor tendinopathy, athletic pubalgia, lumbar spine affections, and others can cause similar symptoms. To determine the prevalence of inguinal and/or femoral herniation and adductor insertion tendinopathy using dynamic ultrasound in a cohort of patients with radiographic evidence of FAI. Case series; Level of evidence, 4. This retrospective study consisted of 74 patients (36 female and 38 male; mean age, 29 years; 83 symptomatic hips) with groin pain and radiographic evidence of FAI. In addition to the usual diagnostic algorithm, all patients underwent a dynamic ultrasound examination for signs of groin herniation and tendinopathy of the proximal insertion of the adductors. Evidence of groin herniation was found in 34 hips (41%). There were 27 inguinal (6 female, 21 male) and 10 femoral (9 female, 1 male) hernias. In 3 cases, inguinal and femoral herniation was coexistent. Overall, 5 patients underwent subsequent hernia repair. Patients with groin herniation were significantly older than those without (33 vs 27 years, respectively; P = .01). There were no significant differences for any of the radiographic or clinical parameters. Tendinopathy of the proximal adductor insertion was detected in 19 cases (23%; 11 female, 8 male). Tendinopathy was coexistent with groin herniation in 8 of the 19 cases. There were no significant differences for any of the radiographic or clinical parameters between patients with or without tendinopathy. Patients with a negative diagnostic hip injection result were more likely to have a concomitant groin hernia than those with a positive injection result (80% vs 27%, respectively). Overall, 38 hips underwent FAI surgery with satisfactory outcomes in terms of score values and subjective improvement. The results demonstrate that groin herniation and adductor insertion tendinopathy coexist frequently in patients with FAI. Although the clinical effect is yet unclear, 5 patients underwent hernia repair. Dynamic ultrasound is a useful tool to detect such pathological abnormalities. Diagnostic hip injections can be helpful to differentiate between the sources of pain. © 2015 The Author(s).

Obesity is a significant and independent risk factor for cardiovascular disease, and assessing ischaemia in obese patients is clinically important but sometimes difficult because of imaging artefacts. The aim of this study was to evaluate the feasibility and diagnostic accuracy of stress/rest imaging with a cadmium-zinc telluride (CZT) camera using a low-dose protocol in a series of consecutive obese patients referred for the evaluation of coronary artery disease. We considered 148 consecutive obese patients (mean BMI 39 ± 7 kg/m(2)) with known or suspected coronary artery disease referred to our laboratory for stress/rest myocardial perfusion imaging. A subgroup of 103 of the 148 patients underwent invasive coronary angiography for clinical reasons. All patients underwent a single-day stress/rest low-dose ultrafast protocol. Patients were injected with (99m)Tc-tetrofosmin at a dose in the range 185-222 MBq during bicycle exercise or dipyridamole stress, and underwent the first scan with an acquisition time of 7 min starting 15 min after the end of the stress. The rest scan with an acquisition time of 6 min was started from 30 to 45 min after (99m)Tc-tetrofosmin injection at a dose in the range 370-444 MBq. Images were visually inspected, and the summed stress score (SSS) and summed rest score (SRS) were obtained. Image quality was graded very good or excellent in all patients. Of the 103 patients who underwent coronary angiography, 12 (12 %), 26 (25 %) and 56 (54 %) showed one-, two- and three-vessel disease, and 9 showed normal coronary vessels. In the 103 patients submitted to coronary angiography, the mean SSS and SRS were 7 ± 6 and 2 ± 3, respectively. Semiquantitative regional and global SSS was a good discriminant of coronary artery disease and the area under the overall ROC curve was 0.848 (95 % CI 0.723-0.975). In obese patients, a single-day stress/rest low-dose ultrafast protocol with a CZT camera is clinically feasible and provides high image quality.

Growth Modulation in Achondroplasia.

PubMed

McClure, Philip K; Kilinc, Eray; Birch, John G

2017-09-01

Achondroplasia is the most common skeletal dysplasia with a rate of nearly 1/10,000. The development of lower extremity deformity is well documented, and various modes of correction have been reported. There are no reports on the use of growth modulation to correct angular deformity in achondroplasia. Medical Records from 1985 to 2015 were reviewed for the diagnosis of achondroplasia and growth modulation procedures. Patients who had been treated for angular deformity of the legs by growth modulation were identified. A detailed analysis of their medical record and preoperative and final lower extremity radiographs was completed. Four patients underwent growth modulation procedures, all to correct existing varus deformity of the legs. Three of the 4 patients underwent bilateral distal femoral and proximal tibial growth modulation. The remaining patient underwent tibial correction only. Two of the 4 patients had a combined proximal fibular epiphysiodesis. All limbs had some improvement of alignment; however, 1 patient went on to bilateral osteotomies. Only 1 limb corrected to a neutral axis with growth modulation alone at last follow-up, initial implantation was done before 5 years of age. Growth modulation is an effective means for deformity correction in the setting of achondroplasia. However implantation may need to be done earlier than would be typical for patients without achondroplasia. Osteotomy may still be required after growth modulation for incomplete correction.

An aging population is an important demographic issue in India. The knowledge base about kidney diseases among the elderly Indians is inadequate. We aim to delineate the clinical profile and spectrum of biopsy-proven kidney disease in elderly patients. Records of all elderly patients (≥60 years) who had undergone kidney biopsy in the nephrology department from January 2010 to December 2014 were reviewed. Their clinical details and laboratory investigations at the time of biopsy were noted. Details of kidney biopsy were recorded from their biopsy reports. In total, 1728 patients underwent kidney biopsy during this period and 124 were elderly (7.2%). Their mean age was 64.9 ± 4.9 years, and they were predominantly males (63.7%). Mean serum creatinine was 3.0 ± 2.8 mg/dl, proteinuria was 4.0 ± 2.7 g/day, and 39.5% had microscopic hematuria. The most common indications for biopsy were nephrotic syndrome (NS)--39.5% and acute kidney injury/rapidly progressive glomerulonephritis (AKI/RPGN)--24.2%. Another 8.1% patients had NS with AKI. MN (39.0%) was the chief cause of NS, and pauci-immune crescentic glomerulonephritis (GN) (28.2%) was the leading cause of AKI/RPGN. MN, pauci-immune crescentic GN and acute on chronic tubulointerstitial nephritis (A/CTIN) and acute tubular injury (ATI) were more common in the elderly, while MCD, FSGS, IgA nephropathy and lupus nephritis were more frequent in the younger patients. 68.5% of the elderly patients biopsied were diagnosed with a renal disease which was potentially amenable to specific treatment. The spectrum of biopsy-proven kidney disease in the elderly Indians seen in our tertiary care hospital varies from the younger population. Kidney biopsy provides useful information with therapeutic and prognostic implications in these patients. The percentage of elderly patients among the total biopsied population is low in India, and these patients present late with renal dysfunction. Prospective studies are needed to assess the outcome of the commonly seen kidney diseases in elderly patients.

Breast cancer awareness and early detection are limited in Sub-Saharan Africa. Resource limitations make screening mammography or clinical breast examination (CBE) by physicians or nurses impractical in many settings. Four laywomen were trained to deliver breast cancer educational talks and conduct CBE. After training, screening was implemented in diverse urban health clinics. Eligible women were 30 years old, with no prior breast cancer or breast surgery, and clinic attendance for reasons other than a breast concern. Women with abnormal CBE were referred to a study surgeon. All palpable masses confirmed by surgeon examination were pathologically sampled. Patients with abnormal screening CBE but normal surgeon examination underwent breast ultrasound confirmation. In addition, 50 randomly selected women with normal screening CBE underwent breast ultrasound, and 45 different women with normal CBE were randomly assigned to surgeon examination. Among 1220 eligible women, 1000 (82%) agreed to CBE. Lack of time (69%) was the commonest reason for refusal. Educational talk attendance was associated with higher CBE participation (83% versus 77%, P ¼ 0.012). Among 1000 women screened, 7% had abnormal CBE. Of 45 women with normal CBE randomised to physician examination, 43 had normal examinations and two had axillary lymphadenopathy not detected by CBE. Sixty of 67 women (90%) with abnormal CBE attended the referral visit. Of these, 29 (48%) had concordant abnormal physician examination. Thirty-one women (52%) had discordant normal physician examination, all of whom also had normal breast ultrasounds. Compared with physician examination, sensitivity for CBE by laywomen was 94% (confidence interval [CI] 79%-99%), specificity 58% (CI, 46%-70%), positive predictive value 48% (CI, 35%-62%), and negative predictive value 96% (CI, 85%-100%). Of 13 women who underwent recommended pathologic sampling of a breast lesion, two had cytologic dysplasia and all others benign Results. CBE uptake in Lilongwe clinics was high. CBE by laywomen compared favourably with physician examination and followup was good. Our intervention can serve as a model for wider implementation. Performance in rural areas, effects on cancer stage and mortality, and cost effectiveness require evaluation.

A clinical retrospective study was conducted. To evaluate the clinical and radiographic outcome of reduction followed by trans-sacral interbody fusion for high-grade spondylolisthesis. In situ posterior interbody fusion with fibula allograft has improved the fusion rates for patients with high-grade spondylolisthesis. The use of this technique in conjunction with partial reduction has not been reported. Nine consecutive patients underwent treatment of high-grade (Grade 3 or 4) spondylolisthesis with partial reduction followed by posterior interbody fusion using cortical allograft. The average age at the time of surgery was 27 years (range, 8-51 years), and the average follow-up period was 43 months (range, 24-72 months). Before surgery, eight patients had low back pain, seven patients had radiating leg pain, and five patients had hamstring tightness. The average grade of spondylolisthesis by Meyerding grading was 3.9 (range, 3-5). Charts and radiographs were evaluated, and outcomes were collected by use of the modified SRS outcomes instrument. Radiographic indexes demonstrated significant improvement with partial reduction and fusion. The slip angle, as measured from the inferior endplate of L5, improved from 41.2 degrees (range, 24-82 degrees ) before surgery to 21 degrees (range, 5-40 degrees ) after surgery. All the patients were extremely or somewhat satisfied with surgery. The two patients who underwent this operation without initial instrumentation experienced fractures of their interbody grafts. Both of these patients underwent repair of the pseudarthrosis with placement of trans-sacral pedicle screw instrumentation and subsequent fusion. Partial reduction followed by posterior interbody fusion is an effective technique for the management of high-grade spondylolisthesis in pediatric and adult patient populations, as assessed by radiographic and clinical criteria. Pedicle screw instrumentation with the sacral screws capturing L5 is recommended when this technique is used for the treatment of high-grade spondylolisthesis. According to the clinical and radiographic results from this study, partial reduction and posterior fibula interbody fusion supplemented with pedicle screw instrumentation is an effective technique for select patients with high-grade spondylolisthesis at L5-S1.

The contemporary management of penetrating splenic injury.

Selective non-operative management (NOM) is standard of care for clinically stable patients with blunt splenic trauma and expectant management approaches are increasingly utilised in penetrating abdominal trauma, including in the setting of solid organ injury. Despite this evolution of clinical practice, little is known about the safety and efficacy of NOM in penetrating splenic injury. Trauma registry and medical record review identified all consecutive patients presenting to LAC+USC Medical Center with penetrating splenic injury between January 2001 and December 2011. Associated injuries, incidence and nature of operative intervention, local and systemic complications and mortality were determined. During the study period, 225 patients experienced penetrating splenic trauma. The majority (187/225, 83%) underwent emergent laparotomy. Thirty-eight clinically stable patients underwent a deliberate trial of NOM and 24/38 (63%) were ultimately managed without laparotomy. Amongst patients failing NOM, 3/14 (21%) underwent splenectomy while an additional 6/14 (42%) had splenorrhaphy. Hollow viscus injury (HVI) occurred in 21% of all patients failing NOM. Forty percent of all NOM patients had diaphragmatic injury (DI). All patients undergoing delayed laparotomy for HVI or a splenic procedure presented symptomatically within 24h of the initial injury. No deaths occurred in patients undergoing NOM. Although the vast majority of penetrating splenic trauma requires urgent operative management, a group of patients does present without haemodynamic instability, peritonitis or radiologic evidence of hollow viscus injury. Management of these patients is complicated as over half may remain clinically stable and can avoid laparotomy, making them potential candidates for a trial of NOM. HVI is responsible for NOM failure in up to a fifth of these cases and typically presents within 24h of injury. Delayed laparotomy, within this limited time period, did not appear to increase mortality nor preclude successful splenic salvage. In clinically stable patients, diagnostic laparoscopy remains essential to evaluate and repair occult DI. As NOM for penetrating abdominal trauma becomes more common, multi-centre data is needed to more accurately define the principles of patient selection and the limitations and consequences of this approach in the setting of splenic injury.

We systematically reviewed the literature concerning simulation-based teaching and assessment of the Accreditation Council for Graduate Medical Education professionalism competencies to elucidate best practices and facilitate further research. A systematic review of English literature for "professionalism" and "simulation(s)" yielded 697 abstracts. Two independent raters chose abstracts that (1) focused on graduate medical education, (2) described the simulation method, and (3) used simulation to train or assess professionalism. Fifty abstracts met the criteria, and seven were excluded for lack of relevant information. The raters, 6 professionals with medical education, simulation, and clinical experience, discussed 5 of these articles as a group; they calibrated coding and applied further refinements, resulting in a final, iteratively developed evaluation form. The raters then divided into 2 teams to read and assess the remaining articles. Overall, 15 articles were eliminated, and 28 articles underwent final analysis. Papers addressed a heterogeneous range of professionalism content via multiple methods. Common specialties represented were surgery (46.4%), pediatrics (17.9%), and emergency medicine (14.3%). Sixteen articles (57%) referenced a professionalism framework; 14 (50%) incorporated an assessment tool; and 17 (60.7%) reported debriefing participants, though in limited detail. Twenty-three (82.1%) articles evaluated programs, mostly using subjective trainee reports. Despite early innovation, reporting of simulation-based professionalism training and assessment is nonstandardized in methods and terminology and lacks the details required for replication. We offer minimum standards for reporting of future professionalism-focused simulation training and assessment as well as a basic framework for better mapping proper simulation methods to the targeted domain of professionalism.

Mesial temporal sclerosis (MTS) is an important pathology in temporal lobe epilepsy (TLE) and often associated with good surgical outcome, however prognostic factors for surgical outcome are conflicting. The authors examine seizure outcome after surgery for TLE due to MTS, with focus on the presence of polyglucosan bodies (PGBs), and its relation to the epileptogenic process. Records of 44 consecutive patients with intractable TLE who underwent anterior temporal lobectomy (ATL) at JFK medical center between 1994-2001 were reviewed. Details of clinical, electrophysiological evaluation, and outcome were collected. All slides were reviewed for the presence of MTS. In twenty-one patients with MTS, detailed histology of surgical specimens was reviewed and relative concentration of PGBs was assessed. The postoperative follow-up duration ranges between 28-74 months. Surgical outcome was evaluated according to Engel's classification. Data of fourteen females (mean age 32.8 years) and 7 males (mean age 34.2) were analyzed. PBGs were identified in 10 patients (8 females and 2 males). All 10 patients had good surgical outcome, with 6 patients (60%) being seizure free (class 1) and 4 patients as class 2. While 11 patients (6 males and 5 females) with absent PGB, 72.8% had good surgical outcome. Of these, 7 (63.8%) had class 1, 1 patient had class 2, and 3 patients had class 3&4. Assessing several risk factors, the only significant difference between the two groups was epilepsy duration, which was significantly longer in patients with PGBs (P = 0.011). The histological presence of PGB is associated with long duration of epilepsy and could be the consequence of epilepsy. Despite prolonged duration of epilepsy, the surgical outcome in PGBs +ve is similar to PGBs -ve patients.

The ongoing 1000 brains study (1000BRAINS) is an epidemiological and neuroscientific investigation of structural and functional variability in the human brain during aging. The two recruitment sources are the 10-year follow-up cohort of the German Heinz Nixdorf Recall (HNR) Study, and the HNR MultiGeneration Study cohort, which comprises spouses and offspring of HNR subjects. The HNR is a longitudinal epidemiological investigation of cardiovascular risk factors, with a comprehensive collection of clinical, laboratory, socioeconomic, and environmental data from population-based subjects aged 45-75 years on inclusion. HNR subjects underwent detailed assessments in 2000, 2006, and 2011, and completed annual postal questionnaires on health status. 1000BRAINS accesses these HNR data and applies a separate protocol comprising: neuropsychological tests of attention, memory, executive functions and language; examination of motor skills; ratings of personality, life quality, mood and daily activities; analysis of laboratory and genetic data; and state-of-the-art magnetic resonance imaging (MRI, 3 Tesla) of the brain. The latter includes (i) 3D-T1- and 3D-T2-weighted scans for structural analyses and myelin mapping; (ii) three diffusion imaging sequences optimized for diffusion tensor imaging, high-angular resolution diffusion imaging for detailed fiber tracking and for diffusion kurtosis imaging; (iii) resting-state and task-based functional MRI; and (iv) fluid-attenuated inversion recovery and MR angiography for the detection of vascular lesions and the mapping of white matter lesions. The unique design of 1000BRAINS allows: (i) comprehensive investigation of various influences including genetics, environment and health status on variability in brain structure and function during aging; and (ii) identification of the impact of selected influencing factors on specific cognitive subsystems and their anatomical correlates.

Alzheimer’s Disease Susceptibility Genes APOE and TOMM40, and Hippocampal Volumes in the Lothian Birth Cohort 1936

The APOE ε and TOMM40 rs10524523 (‘523’) variable length poly-T repeat gene loci have been significantly and independently associated with Alzheimer’s disease (AD) related phenotypes such as age of clinical onset. Hippocampal atrophy has been significantly associated with memory impairment, a characteristic of AD. The current study aimed to test for independent effects of APOE ε and TOMM40 ‘523’ genotypes on hippocampal volumes as assessed by brain structural MRI in a relatively large sample of community-dwelling older adults. As part of a longitudinal study of cognitive ageing, participants in the Lothian Birth Cohort 1936 underwent genotyping for APOE ε2/ε3/ε4 status and TOMM40 ‘523’ poly-T repeat length, and detailed structural brain MRI at a mean age of 72.7 years (standard deviation = 0.7, N range = 624 to 636). No significant effects of APOE ε or TOMM40 523 genotype were found on hippocampal volumes when analysed raw, or when adjusted for either intracranial or total brain tissue volumes. In summary, in a large community-dwelling sample of older adults, we found no effects of APOE ε or TOMM40 523 genotypes on hippocampal volumes. This is discrepant with some previous reports of significant association between APOE and left/right hippocampal volumes, and instead echoes other reports that found no association. Previous significant findings may partly reflect type 1 error. Future studies should carefully consider: 1) their specific techniques in adjusting for brain size; 2) assessing more detailed sub-divisions of the hippocampal formation; and 3) testing whether significant APOE-hippocampal associations are independent of generalised brain atrophy.

The current study aimed to test for independent effects of APOE ε and TOMM40 '523' genotypes on hippocampal volumes as assessed by brain structural MRI in a relatively large sample of community-dwelling older adults. As part of a longitudinal study of cognitive ageing, participants in the Lothian Birth Cohort 1936 underwent genotyping for APOE ε2/ε3/ε4 status and TOMM40 '523' poly-T repeat length, and detailed structural brain MRI at a mean age of 72.7 years (standard deviation = 0.7, N range = 624 to 636). No significant effects of APOE ε or TOMM40 523 genotype were found on hippocampal volumes when analysed raw, or when adjusted for either intracranial or total brain tissue volumes. In summary, in a large community-dwelling sample of older adults, we found no effects of APOE ε or TOMM40 523 genotypes on hippocampal volumes. This is discrepant with some previous reports of significant association between APOE and left/right hippocampal volumes, and instead echoes other reports that found no association. Previous significant findings may partly reflect type 1 error. Future studies should carefully consider: 1) their specific techniques in adjusting for brain size; 2) assessing more detailed sub-divisions of the hippocampal formation; and 3) testing whether significant APOE-hippocampal associations are independent of generalised brain atrophy.

To validate a protocol for creating virtual models to be used in the construction of solid prototypes useful for the planning-simulation of maxillo-facial surgery, in particular for very complex anatomic and pathologic problems. To optimize communications between the radiology, engineering and surgical laboratories. We studied 16 patients with different clinical problems of the maxillo-facial district. Exams were performed with multidetector computed tomography (MDCT) and single slice computed tomography (SDCT) with axial scans and collimation of 0.5-2 mm, and reconstruction interval of 1 mm. Subsequently we performed 2D multiplanar reconstructions and 3D volume-rendering reconstructions. We exported the DICOM images to the engineering laboratory, to recognize and isolate the bony structures by software. With these data the solid prototypes were generated using stereolitography. To date, surgery has been preformed on 12 patients after simulation of the procedure on the stereolithographyc model. The solid prototypes constructed in the difficult cases were sufficiently detailed despite problems related to the artefacts generated by dental fillings an d prostheses. In the remaining cases the MPR/3D images were sufficiently detailed for surgical planning. The surgical results were excellent in all patients who underwent surgery, and the surgeons were satisfied with the improvement in quality and the reduction in time required for the procedure. MDCT enables rapid prototyping using solid replication, which was very helpful in maxillo-facial surgery, despite problems related to artifacts due to dental fillings and prosthesis within the acquisition field; solutions for this problem are work in progress. The protocol used for communication between the different laboratories was valid and reproducible.

To determine the clinical characteristics and the results of bronchoscopic treatment of children due to foreign body aspiration in a university hospital. Department of Otorhinolaryngology and Maxillofacial Surgery, University Clinical Center Tuzla, Bosnia and Hercegovina. The analysis of the cases of aspirated foreign bodies within the period from January 1954 to December 2004. The analyzed patients were the children up to 14 years of age. All cases underwent the bronchoscopy. Each patient was analyzed for age, sex, nature and location of the foreign body, results of bronchoscopic removal, complications of bronchoscopy and presence of foreign bodies in the airways. Six hundred and sixty-two children who underwent bronchoscopy for removal of foreign body in the airways were evaluated. From evaluated children 66.8% were boys, ages ranging from 9 months to 14 years. Foreign bodies were more frequent in children under 3 years of age (65.2%). Most of the foreign bodies removed were organic (87.1%) and more frequently found in the right bronchial tree (53%). More attention is necessary to the prevention of aspirations. Prevention of aspiration of foreign bodies is better than cure. Public awareness through mass media needs attention to prevent foreign body inhalation.

Randomized clinical trials have not shown survival differences between breast cancer patients who undergo breast-conserving surgery and those who undergo modified radical mastectomy (MRM). Recent studies however, have suggested that these randomized clinical trials findings may not be representative of the entire population or the nature of current patient care. A retrospective analysis of female invasive breast cancer patients who underwent surgery in the Surveillance, Epidemiology, and End Results database (1990-2003) was performed. Survival was compared amongst women who underwent partial mastectomy, partial mastectomy plus radiation (PMR), or MRM. Cox proportional hazards regressions were used to investigate the impact of method of treatment upon survival, after adjusting for patient and tumor characteristics. A total of 218,043 patients, mean age 62 years, were identified. MRM accounted for 51.5 per cent of the study population whereas PMR accounted for 34.9 per cent. On multivariate analyses, significant improvement was observed in patient survival associated with PMR when compared with MRM patients (hazard ratio = 0.71, 95% confidence interval = 0.67-0.74, P < 0.001). This population-based study suggests that there is a survival benefit for women undergoing PMR in the treatment of breast cancer.

Augmentative and alternative communication devices proved to be effective in patients with severe intellectual disability to overcome their communication impairments. In order to give a contribution for design of augmentative and alternative communication systems that better meet the needs of beginning communicators we decided to report our clinical experience about using augmentative and alternative communication in adolescents with severe intellectual disability. Five patients who underwent a long time traditional speech rehabilitation program (at least 5 years) with scant improvements in linguistic function were recruited and evaluated by means of the Vineland Adaptive Behaviour Scale before and after a three years augmentative and alternative communication intervention carried out by a multidisciplinary team. After the rehabilitative intervention patients showed an improvement in communication, daily living skills and socialization as measured by the Vineland Adaptive Behaviour Scale. Augmentative and alternative communication is an effective rehabilitation approach to people with severe intellectual disability and impairments in linguistic expression. Moreover augmentative and alternative communication is a useful tool allowing these patients to increase their social participation also enhancing their self-esteem. Our clinical experience confirmed these topics also in adolescents who underwent a long time traditional speech rehabilitation program with scant improvements, providing practical information to clinicians.

We now have considerable experience in the use of biologic agents to treat psoriasis, but doubts about management arise in certain clinical settings. Surgery is one of them. Although treatment guidelines advise that biologics be suspended before major surgery, data about actual clinical practices and associated complications are lacking. We aimed to analyze current practice in the clinical management of these cases. Retrospective study of cases in the Biobadaderm database. We analyzed the management of biologic therapy in patients with psoriasis who underwent surgical procedures. Forty-eight of the 2113 patients registered in Biobadaderm underwent surgery. The largest percentage of procedures (31%) involved skin lesions. Biologic treatment was interrupted in 42% of the cases. No postsurgical complications were significantly related to treatment interruption. Likewise we detected no associations between treatment interruption and other variables, such as sex, age, or duration or severity of psoriasis. Continuity of biologic treatment and the risk of postsurgical complications were not associated in this study, although conclusions are limited by the small sample size. Copyright © 2016 AEDV.

Background: Juvenile Recurrent Parotitis (JRP) is a recurrent parotid inflammation of childhood.  The aim of our study was to investigate the clinical, laboratory and imaging profile of children with JRP as well as to estimate the impact of siadendoscopy as a therapeutic tool in the clinical outcome of JRP. Methods: Twenty-three children with JRP aged 3.5-16 years, were investigated. Twelve of them underwent sialendoscopy: seven aged <8 years under general and five aged >8 years under local anesthesia. Results: The age at onset ranged from 2-15 years while the number of episodes from 2-8 per year. The autoantibody profile was negative in all patients, suggesting no evidence for autoimmune diseases.  Antibody deficiency was found in two children. The imaging studies reveal an overall parotid swelling and intraparotid lymph nodes while microabscesses were present in 31% of the patients. Twelve patients who underwent sialendoscopy had a significant improvement in their clinical outcome; the mean episodes of JRP before sialendoscopy was 3.9/year and reduced to 0.4 at the post-intervention year. Conclusion: Sialendoscopy represents an alternative and promising perspective in the management of JRP. Hippokratia 2015; 19 (4): 356-359. PMID:27688702

Rectus sheath hematoma (RSH) is a rare clinical entity. It can be mistaken for other intra-abdominal disorders, which can result in diagnostic and therapeutic difficulties. This study was undertaken to analyze the clinical presentation, diagnostic modalities, and management of patients affected with RSH. Between January 2008 and June 2011, eight patients (5 men and 3 women with a mean age of 53 years) with RSH were evaluated according to demographic characteristics, clinical and radiological findings, and methods of treatment. Six patients developed RSH after anticoagulant therapy; one after local trauma, and one after laparoscopic intervention. Six patients were treated nonsurgically; one patient underwent embolization of the inferior epigastric artery and one underwent ligation of the bleeding vessel. The average hospital stay was 6 days. There were no mortality or thromboembolic complications. RSH is a rare nonneoplastic entity that is usually associated with abdominal trauma and/or anticoagulant therapy. The gold standard for diagnosis is computed tomography, and ultrasonography can be used in follow-up. The treatment of choice is nonsurgical therapy because RSH is a self-limited condition. Surgical intervention should be reserved for cases with hemodynamic instability. Copyright © 2013. Published by Elsevier B.V.

Screening for prodromal Parkinson's disease in the general community: a sleep-based approach.

Neuroprotective therapy for Parkinson's disease (PD) is most likely to be effective if provided in its prodromal stages. However, identifying prodromal PD is difficult because PD is relatively uncommon, and most markers are nonspecific. Rapid eye movement (REM) sleep behavior disorder (RBD) is by far the strongest clinical marker of prodromal PD, but most patients do not seek out medical attention. Developing an efficient way of diagnosing RBD from the general community may be the most practical method to detect prodromal PD. We developed a screening strategy that began with a newspaper advertisement containing a single-question screen for RBD. All screen-positive subjects underwent an interview based on the Innsbruck RBD inventory aimed to optimize the positive predictive value. Those who passed both screens underwent confirmatory polysomnography. The proportion of screened RBD patients who met the International Parkinson and Movement Disorder Society (MDS) criteria for prodromal PD was assessed. A broad array of clinical markers of neurodegeneration was compared between newspaper-screened RBD patients and 130 RBD patients clinically referred to the sleep center. Of 111 RBD-screen-positive participants, 40 (36%) passed the secondary screen, and 29 underwent full polysomnography. Of these 29 patients, 19 were ultimately proven to have RBD (PPV = 66%), 12 (63%) of whom met the criteria for prodromal PD. Compared to patients referred to the sleep center, newspaper-screened patients had similar age, sex, olfaction, autonomic function, and color vision. However, motor and cognitive assessments were slightly better in newspaper-screened patients. A multistep screening approach using RBD screening questionnaires and telephone follow-up can efficiently identify prodromal PD in the general community. Copyright © 2016 Elsevier B.V.

Loeys-Dietz syndrome (LDS) is a recently recognized aggressive aortic disorder characterized by root aneurysm, arterial tortuosity, hypertelorism, and bifid uvula or cleft palate. The results of prophylactic root replacement using valve-sparing procedures (valve-sparing root replacement [VSRR]) in patients with LDS is not known. We reviewed all patients with clinical and genetic (transforming growth factor-β receptor mutations) evidence of LDS who underwent VSRR at our institution. Echocardiographic and clinical data were obtained from hospital and follow-up clinic records. From 2002 to 2009, 31 patients with a firm diagnosis of LDS underwent VSRR for aortic root aneurysm. Mean age was 15 years, and 24 (77%) were children. One (3%) patient had a bicuspid aortic valve. Preoperative sinus diameter was 3.9±0.8 cm (z score 7.0±2.9) and 2 (6%) had greater than 2+ aortic insufficiency. Thirty patients (97%) underwent reimplantation procedures using a Valsalva graft. There were no operative deaths. Mean follow-up was 3.6 years (range, 0 to 7 years). One patient required late repair of a pseudoaneurysm at the distal aortic anastomosis, and 1 had a conversion to a David reimplantation procedure after a Florida sleeve operation. No patient suffered thromboembolism or endocarditis, and 1 (3%) patient experienced greater than 2+ late aortic insufficiency. No patient required late aortic valve repair or replacement. Loeys-Dietz syndrome is an aggressive aortic aneurysm syndrome that can be addressed by prophylactic aortic root replacement with low operative risk. Valve-sparing procedures have encouraging early and midterm results, similar to those in Marfan syndrome, and are an attractive option for young patients.

2005-06-01

This study evaluated the ability of a novel intraoperative neurophysiologic monitoring method used to locate the axillary nerve, predict relative capsule thickness, and identify impending injury to the axillary nerve during arthroscopic thermal capsulorrhaphy of the shoulder. Prospective cohort study. Twenty consecutive patients with glenohumeral instability were monitored prospectively during arthroscopic shoulder surgery. Axillary nerve mapping and relative capsule thickness estimates were recorded before the stabilization portion of the procedure. During labral repair and/or thermal capsulorrhaphy, continuous and spontaneous electromyography recorded nerve activity. In addition, trans-spinal motor-evoked potentials of the fourth and fifth cervical roots and brachial plexus electrical stimulation, provided real-time information about nerve integrity. Axillary nerve mapping and relative capsule thickness were recorded in all patients. Continuous axillary nerve monitoring was successfully performed in all patients. Eleven of the 20 patients underwent thermal capsulorrhaphy alone or in combination with arthroscopic labral repair. Nine patients underwent arthroscopic labral repair alone. In 4 of the 11 patients who underwent thermal capsulorrhaphy, excessive spontaneous neurotonic electromyographic activity was noted, thereby altering the pattern of heat application by the surgeon. In 1 of these 4 patients, a small increase in the motor latency was noted after the procedure but no clinical deficit was observed. There were no neuromonitoring or clinical neurologic changes observed in the labral repair group without thermal application. At last follow-up, no patient in either group had any clinical evidence of nerve injury or complications from neurophysiologic monitoring. We successfully evaluated the use of intraoperative nerve monitoring to identify axillary nerve position, capsule thickness, and provide real-time identification of impending nerve injury and function during shoulder thermal capsulorrhaphy. The use of intraoperative nerve monitoring altered the heat application technique in 4 of 11 patients and may have prevented nerve injury. Level II, prospective cohort study.

To determine acute computed tomography perfusion (CTP) changes in seizure patients presenting with stroke-like symptoms and to correlate those changes with clinical presentation and electroencephalography (EEG). The medical records of all patients who presented to the emergency department with acute stroke-like symptoms and underwent CTP (n=1085) over a 5.5-year period were reviewed. Patients were included who had primary seizure as the final diagnosis, and underwent CTP within 3 hours of symptom onset. A subset of patients had a follow-up EEG within 7 days. The perfusion changes and EEG findings were compared between different clinical presentations. Eighteen of 1085 patients (1.7%) who underwent CTP following an acute stroke-like presentation were included. The abnormality on CTP was usually focal, unilateral hyperperfusion - increased relative cerebral blood flow (rCBF) and volume (rCBV) (n=14/18), which most often affected the temporal lobe. Those patients who presented with a motor or speech deficit (n=12) had a higher temporal lobe rCBV, and rCBF, and lower relative mean transit time (rMTT) compared to those with non-focal neurological deficit at presentation. Early EEG was available in 13 patients; a sharp-spike epileptiform EEG discharge pattern (n=5) was associated with higher temporal lobe ipsilateral rCBF and rCBV, and lower rMTT on admission CTP examination. Seizure patients who present with a unilateral motor or speech deficit most commonly have contralateral hyperperfusion in the corresponding eloquent brain regions on the acute-stage CTP examination. In such patients, epileptiform discharges on the early follow-up EEG are associated with ipsilateral hyperperfusion on the admission CTP. Copyright © 2015 The Royal College of Radiologists.

Successful percutaneous coronary intervention (PCI) of the occluded infarct-related artery (IRA) in latecomers may improve long-term survival mainly by reducing left ventricular remodeling. It is not clear whether inhibition of renin-angiotensin system (RAS) brings additional better clinical outcomes in this specific population subset. Between January 2008 and June 2013, 669 latecomer patients with acute ST-segment elevation myocardial infarction (STEMI) (66.2±12.1 years, 71.0% males) in Korea Acute Myocardial Infarction Registry (KAMIR) who underwent a successful PCI were enrolled. The study population underwent a successful PCI for a totally occluded IRA. They were divided into two groups according to whether they were prescribed RAS inhibitors at the time of discharge: group I (RAS inhibition, n=556), and group II (no RAS inhibition, n=113). During the one-year follow-up, major adverse cardiac events (MACE), which consist of cardiac death and myocardial infarction, occurred in 71 patients (10.6%). There were significantly reduced incidences of MACE in the group I (hazard ratio=0.34, 95% confidence interval 0.199-0.588, p=0.001). In subgroup analyses, RAS inhibition was beneficial in patients with male gender, history of hypertension or diabetes mellitus, and even in patients with left ventricular ejection fraction (LVEF) ≥40%. In the baseline and follow-up echocardiographic data, benefit in changes of LVEF and left ventricular end-systolic volume was noted in group I. In latecomers with STEMI, RAS inhibition improved long-term clinical outcomes after a successful PCI, even in patients with low risk who had relatively preserved LVEF.

Surgery for perforated peptic ulcer (PPU) is associated with a risk of complications. The frequency and severity of reoperative surgery is poorly described. The aims of the present study were to characterize the frequency, procedure-associated risk and mortality associated with reoperation after surgery for PPU. All patients treated surgically for PPU in Denmark between 2011 and 2013 were included. Baseline and clinical data, including 90-day mortality and detailed information on reoperative surgery, were collected from the Danish Clinical Register of Emergency Surgery. Distribution frequencies of reoperation stratified by type of surgical approach (laparoscopy or open) were reported. The crude and adjusted risk associations between surgical approach and reoperation were assessed by regression analysis and reported as odds ratio (OR) with 95 per cent c.i. Sensitivity analyses were carried out. A total of 726 patients were included, of whom 238 (32·8 per cent) were treated laparoscopically and 178 (24·5 per cent) had a laparoscopic procedure converted to laparotomy. Overall, 124 (17·1 per cent) of 726 patients underwent reoperation. A persistent leak was the most frequent cause (43 patients, 5·9 per cent), followed by wound dehiscence (34, 4·7 per cent). The crude risk of reoperative surgery was higher in patients who underwent laparotomy and those with procedures converted to open surgery than in patients who had laparoscopic repair: OR 1·98 (95 per cent c.i. 1·19 to 3·27) and 2·36 (1·37 to 4·08) respectively. The difference was confirmed when adjusted for age, surgical delay, co-morbidity and American Society of Anesthesiologists fitness grade. However, the intention-to-treat sensitivity analysis (laparoscopy including conversions) demonstrated no significant difference in risk. The risk of death within 90 days was greater in patients who had reoperation: crude and adjusted OR 1·53 (1·00 to 2·34) and 1·06 (0·65 to 1·72) respectively. Reoperation was necessary in almost one in every five patients operated on for PPU. Laparoscopy was associated with lower risk of reoperation than laparotomy or a converted procedure. However, there was a risk of bias, including confounding by indication. © 2015 BJS Society Ltd Published by John Wiley & Sons Ltd.

There have been significant developments in Ebola virus therapeutics. While the efficacy of several products was evaluated in the recent West Africa outbreak, a licensed treatment for EBOV disease remains elusive. Factors that negatively impacted the execution of clinical trials included an overall lack of world readiness to conduct clinical trials in an outbreak setting, ethical concerns limiting implementation of the randomized controlled trials in an outbreak setting, and a decline in case numbers by the time resources were mobilized to conduct clinical trials. We summarize relevant therapeutics that underwent clinical trials during the West Africa outbreak and highlight promising candidates under advanced development. Published by Elsevier Ltd.

Laparoscopic bile duct exploration has become one of the main options for the treatment of choledocholithiasis associated with cholelithiasis. Our objective is to describe the results of a consecutive series of patients. We retrospectively analyzed 101 (66 female/16 male) patients who underwent laparoscopic bile duct exploration. Age was 58 +/- 18 years. We analyzed operaion time, hospital stay and postoperative complications according to the surgical approach (transcystic or choledochotomy). Clinical follow up was carried out for 90 days after surgery and then subsequently by telephone. 1435 laparoscopic cholecystectomies were performed between January 1998 and December 2005. Of those, 101 of those patients underwent laparoscopic bile duct exploration for cholelithiasis and common bile duct stones. We evaluated clinical, laboratory and ultrasound predictors: 70 patients had positive and 31 negative predictors. Laparoscopic transcystic approach was successful in 78 patients and laparoscopic choledochotomy in 17 patients. Operation time was 154 +/- 59 minutes and hospital stay 4.31 +/- 3.44 days. Six patients (5.9%) were converted to open surgery. Two patients were re-operated for postoperative bile leakage. The overall effectiveness was 94%. Postoperative mortality was 0.99%. Median follow up was 51 months. Three patients died of unrelated conditions, three underwent ERCP and one had transfistular extraction for retained stones (3.96%). Laparoscopic treatment for common bile duct stones associated with gallbladder stones is a highly effective procedure with a low incidence of retained stones.

462 patients presenting with chest pain to a rural district general hospital underwent calcium scoring and pretest clinical risk assessment in order to stratify subsequent investigations and treatment was retrospectively reviewed. The patients were followed up for two years and further investigations and outcomes recorded. Of the 206 patients with zero calcium score, 132 patients were immediately discharged from cardiac follow-up with no further investigation on the basis of their calcium score, low pretest risk of coronary artery disease, and no significant incidental findings. After further tests, 267 patients were discharged with no further cardiac therapy, 88 patients were discharged with additional medical therapy, and 19 patients underwent coronary artery by-pass grafting or percutaneous intervention. 164 patients with incidental findings on the chest CT (computed tomography) accompanying calcium scoring were reviewed, of which 88 patients underwent further tests and follow-up for noncardiac causes of chest pain. The correlations between all major risk factors and calcium scores were weak except for a combination of diabetes and hypertension in the male gender (P = 0.012), The use of calcium scoring and pretest risk appeared to reduce the number of unnecessary cardiac investigations in our patients: however, the calcium scoring test produced a high number of incidental findings on the associated CT scans.

Routine contrast esophagram has been shown to be increasingly limited in diagnosing anastomotic leaks after esophagectomy. Patients undergoing esophagectomy from 2013 to 2014 at Huai'an First Peoples' Hospital were identified. We retrospectively analyzed patients who underwent routine contrast esophagram on postoperative day 7 (range 6-10) to preclude anastomotic leaks after esophagectomy. In 846 patients who underwent esophagectomy, a cervical anastomosis was performed in 286 patients and an intrathoracic anastomosis in 560 patients. There were 57 (6.73%) cases with anastomotic leaks, including cervical leaks in 36 and intrathoracic leaks in 21 patients. In the cervical anastomotic leak patients, 13 were diagnosed by early local clinical symptoms and 23 underwent routine contrast esophagram. There were 7 (30.4%) true-positive, 11 (47.8%) false-negative, and five (21.8%) equivocal cases. In the intrathoracic anastomotic leak patients, four (19%) were diagnosed by clinical symptoms, 16 (76.2%) were true positives, and one (4.8%) was a false negative. Aspiration occurred in five patients with cervical anastomoses and in eight patients with intrathoracic anastomoses; aspiration pneumonitis did not occur in these cases. Gastrografin and barium are safe contrast agents to use in post-esophagectomy contrast esophagram. Because of the low sensitivity in detecting cervical anastomotic leaks, routine contrast esophagram is not advised. For patients with intrathoracic anastomoses, it is still an effective method for detecting anastomotic leaks.

We divided into three groups, according to electronystagmography findings and type of anesthesia, 21 men older than 65 years (mean age, 72 years) who were scheduled for prostate adenectomy. One group, designated GBN, consisted of normal subjects who underwent surgery under GBA. In another group, designated GBP, were pathological subjects who had clinically compensated central vestibular disorders (CVDs) and underwent surgery under GBA. The third group, designated SP, contained CVD patients who underwent surgery under SA. We assessed balance control via static posturography preoperatively and 48 hours postoperatively. We observed no change in balance control parameters (center of pressure distribution area [COPa] or COP sway velocity [SV]) for those patients in the GBN group or for those in the SP group. We did observe a significant difference for the patients in the GBP group, with higher postoperative values of COPa and SV (Wilcoxon signed rank test). Our results showed that in subjects with clinically compensated underlying CVD prior to a GBA, balance control worsens after the procedure, whereas no change in balance control occurs after an SA. Balance control in subjects with normal vestibuloocular function did not change even after a GBA.

Our purpose was to review needle aspiration of breast abscesses and identify factors associated with treatment by aspiration alone versus aspiration with surgical incision and drainage (I/D). This Institutional Review Board-approved, retrospective review of the breast ultrasound database from 2008 to 2010 identified 40 patients (41 abscesses) who underwent aspiration, with or without I/D. Demographics, imaging, number of aspirations, and microbiology were reviewed. Twenty-two abscesses underwent aspiration only, 16 > 3 cm, 6 ≤ 3 cm (mean 4.3 cm, range 0.9-10 cm). Known risk factors included lactational (11), 3 weeks post partum (1), pregnancy (1), recent biopsy/lumpectomy (5). Nineteen abscesses underwent aspiration and I/D, 15 > 3 cm, 4 ≤ 3 cm (mean 4.1 cm, range 2.2-7.5 cm). Known risk factors included lactational (4), recurrent subareolar abscess (4), diabetes (3), hydradenitis suppuritiva (1), nipple piercing (2), smoking (1), pregnancy (1), HIV (1), and lumpectomy (1). Identified reasons for I/D included lack of improvement/recurrence (12), fistula (3), and one electively after clinical improvement of a recurrent subareolar abscess. Abscesses associated with pregnancy and lactation or breast biopsy are effectively managed with aspiration, even when large. Recurrence, chronicity, or fistula may require surgical intervention. © 2014 Wiley Periodicals, Inc.

To describe a novel balloon sizing technique used during adult transcatheter patent ductus arteriosus (PDA) closure. In addition, to determine the clinical and procedural outcomes in six patients who underwent PDA balloon sizing with subsequent deployment of a PDA occluder device. Transcatheter PDA closure in adults has excellent safety and procedural outcomes. However, PDA sizing in adults can be challenging due to variable defect size, high flow state, or anatomical complexity. We describe a series of six cases where the balloon- pull through technique was successfully performed for PDA sizing prior to transcatheter closure. Consecutive adult patients undergoing adult PDA closure at our institution were studied retrospectively. A partially inflated sizing balloon was pulled through the defect from the aorta into the pulmonary artery and the balloon waist diameter was measured. Procedural success and clinical outcomes were obtained. Six adult patients underwent successful balloon pull-through technique for PDA sizing during transcatheter PDA closure, since conventional angiography often gave suboptimal opacification of the defect. All PDAs were treated with closure devices based on balloon PDA sizing with complete closure and no complications. In three patients that underwent preprocedure computed tomography, the balloon size matched the CT derived measurements. The balloon pull-through technique for PDA sizing is a safe and accurate sizing modality in adults undergoing transcatheter PDA closure. © 2017 Wiley Periodicals, Inc.

OBJECTIVE Endoscopic third ventriculostomy (ETV) is now established as a viable treatment option for a subgroup of children with hydrocephalus. Here, the authors report prospective, multicenter results from the Hydrocephalus Clinical Research Network (HCRN) to provide the most accurate determination of morbidity, complication incidence, and efficacy of ETV in children and to determine if intraoperative predictors of ETV success add substantially to preoperative predictors. METHODS All children undergoing a first ETV (without choroid plexus cauterization) at 1 of 7 HCRN centers up to June 2013 were included in the study and followed up for a minimum of 18 months. Data, including detailed intraoperative data, were prospectively collected as part of the HCRN's Core Data Project and included details of patient characteristics, ETV failure (need for repeat hydrocephalus surgery), and, in a subset of patients, postoperative complications up to the time of discharge. RESULTS Three hundred thirty-six eligible children underwent initial ETV, 18.8% of whom had undergone shunt placement prior to the ETV. The median age at ETV was 6.9 years (IQR 1.7-12.6), with 15.2% of the study cohort younger than 12 months of age. The most common etiologies were aqueductal stenosis (24.8%) and midbrain or tectal lesions (21.2%). Visible forniceal injury (16.6%) was more common than previously reported, whereas severe bleeding (1.8%), thalamic contusion (1.8%), venous injury (1.5%), hypothalamic contusion (1.5%), and major arterial injury (0.3%) were rare. The most common postoperative complications were CSF leak (4.4%), hyponatremia (3.9%), and pseudomeningocele (3.9%). New neurological deficit occurred in 1.5% cases, with 0.5% being permanent. One hundred forty-one patients had documented failure of their ETV requiring repeat hydrocephalus surgery during follow-up, 117 of them during the first 6 months postprocedure. Kaplan-Meier rates of 30-day, 90-day, 6-month, 1-year, and 2-year failure-free survival were 73.7%, 66.7%, 64.8%, 61.7%, and 57.8%, respectively. According to multivariate modeling, the preoperative ETV Success Score (ETVSS) was associated with ETV success (p < 0.001), as was the intraoperative ability to visualize a "naked" basilar artery (p = 0.023). CONCLUSIONS The authors' documented experience represents the most detailed account of ETV results in North America and provides the most accurate picture to date of ETV success and complications, based on contemporaneously collected prospective data. Serious complications with ETV are low. In addition to the ETVSS, visualization of a naked basilar artery is predictive of ETV success.

Background The microTargeting™ platform (MTP) stereotaxy system (FHC Inc., Bowdoin, Me., USA) was FDA approved in 2001 utilizing rapid-prototyping technology to create custom platforms for human stereotaxy procedures. It has also been called the STarFix (surgical targeting fixture) system since it is based on the concept of a patient- and procedure-specific surgical fixture. This is an alternative stereotactic method by which planned trajectories are incorporated into custom-built, miniature stereotactic platforms mounted onto bone fiducial markers. Our goal is to report the clinical experience with this system over a 6-year period. Methods We present the largest reported series of patients who underwent deep brain stimulation (DBS) implantations using customized rapidly prototyped stereotactic frames (MTP). Clinical experience and technical features for the use of this stereotactic system are described. Final lead location analysis using postoperative CT was performed to measure the clinical accuracy of the stereotactic system. Results Our series included 263 patients who underwent 284 DBS implantation surgeries at one institution over a 6-year period. The clinical targeting error without accounting for brain shift in this series was found to be 1.99 mm (SD 0.9). Operating room time was reduced through earlier incision time by 2 h per case. Conclusion Customized, miniature stereotactic frames, namely STarFix platforms, are an acceptable and efficient alternative method for DBS implantation. Its clinical accuracy and outcome are comparable to those associated with traditional stereotactic frame systems. PMID:21160241

Purpose: To evaluate the clinical outcome for uterine adenomyosis with or without uterine leiomyomata 40 months after uterine artery embolization (UAE). Methods: Forty women aged 39-56 years (median 46 years) with symptomatic uterine adenomyosis and magnetic resonance imaging findings of uterine adenomyosis with or without combined uterine leiomyomata underwent UAE. Self-perceived changes in clinical symptoms were assessed, and residual symptom severity and health-related quality of life (HRQOL) after UAE were evaluated. Clinical failure was defined as no symptomatic improvement or second invasive therapy after UAE. Results were stratified by the extent of uterine adenomyosis at baseline magnetic resonance imaging. Results:more » Patients were followed for a median of 40 months (range 5-102 months). UAE led to symptomatic control after UAE in 29 (72.5%) of 40 patients while 11 women underwent hysterectomy (n = 10) or dilatation and curettage (n = 1) for therapy failure. No significant difference between women with pure uterine adenoymosis and women with uterine adenomyosis combined with uterine leiomyomata was observed. Best results were shown for UAE in uterine adenomyosis with uterine leiomyomata predominance as opposed to predominant uterine adenomyosis with minor fibroid disease (clinical failure 0% vs. 31.5%, P = 0.058). Throughout the study group, HRQOL score values increased and symptom severity scores decreased after UAE. Least improvement was noted for women with pure adenomyosis. Conclusions: UAE is clinically effective in the long term in most women with uterine adenomyosis. Symptomatic control and HRQOL were highest in patients with combined disease of uterine adenomyosis but leiomyomata predominance.« less

Enucleation is increasingly performed for benign or borderline tumours of the pancreas because it is a parenchyma-sparing and less invasive procedure compared to conventional pancreatectomy, which reduces the risk of exocrine and endocrine insufficiency. This study retrospectively evaluated and compared the pre-, intra-, and post-operative clinical characteristics after open and robotic approaches for pancreatic enucleation. Fifty-six cases of enucleation for benign or borderline tumours of the pancreas treated from March 2010 to July 2015 were identified by a retrospective search. These included 25 patients who underwent an open approach and 31 patients who underwent a robotic approach. The clinical characteristics were extracted and compared. The two groups had a similar location and pathology of the tumour. The robotic group had a significantly shorter operation time and significantly less blood loss than the open group. The rates of clinical pancreatic fistula (PF) formation and major complications were similar. The robotic approach could be applied for a tumour on the right side of the pancreas without increasing the incidence of clinical PF or other major complications. The patients with clinical PF had a significantly shorter distance between the lesion and the main pancreatic duct (MPD). Robotic enucleation appears to be a feasible and safe approach for benign or borderline tumours of the pancreas and was associated with similarly favourable surgical outcomes as the open approach. Identifying and avoiding the MPD is an important step during enucleation.

Chronic productive cough is a common clinical problem; often potential causes outside the lower respiratory tract are forgotten or ignored. The aim of this study was to make a precise etiopathogenetic diagnosis of chronic productive cough in young adults. In a clinical setting, 212 subjects (mean age 41+/-5 years) who had reported chronic productive cough in a previous postal survey of a young adult population underwent within two years clinical and functional investigations following a rational diagnostic approach. Two pulmonologists independently established the diagnosis using a clinically structured interview on nasal and respiratory symptoms, spirometry and other tests when appropriate (bronchodilator test or methacholine bronchial challenge, chest radiography); if rhino-sinusitis was suspected, subjects underwent an ENT examination with nasal endoscopy and/or sinus computed tomography. At the end of the diagnostic procedure, 87 subjects (41%) no longer had chronic productive cough and had normal function. Fifty-eight subjects (27%) had chronic rhino-sinusitis; seventeen subjects (8%) had asthma, and of these fourteen also had chronic rhino-sinusitis; 50 subjects (24%) had COPD stage 0+, of these seven also had chronic rhino-sinusitis. Chronic rhino-sinusitis was more frequent in females than in males (p<0.05). Both in clinical practice and in epidemiological studies, it is important to consider that the origin of chronic productive cough could be frequently outside the lower respiratory tract; a consistent percentage of young adults with persistent productive cough has indeed chronic rhino-sinusitis.

To evaluate the role of endometrial injury in the cycle preceding ovarian stimulation for intrauterine insemination (IUI) cycle on the clinical pregnancy rate. This was a prospective randomized controlled trial which included three hundred and thirty two infertile women with an indication for IUI. The subjects were randomly divided into two groups. The intervention group (group A) (n=166) subjects underwent office hysteroscopy with endometrial injury using grasping forceps with teeth, while the control group (group B) (n=166) subjects underwent office hysteroscopy alone without endometrial injury. Primary outcome was clinical pregnancy rate. There were no significant differences in baseline or clinical characteristics between the groups. There were no significant differences in clinical pregnancy rate [13.8% (23/166) versus 12% (20/166); RR 1.15 (95% CI 0.66-2.01), p=0.62]. The abortion rate [4.3% (1/23) versus 15% (3/20); RR 0.29 (95% CI 0.03-2.57), p=0.27], the multiple pregnancy rate [13% (3/23) versus 15% (3/20); RR 0.87 (95% CI 0.20-3.83), p=0.85] and the live birth rate [13.6% (22/166) versus 10.4% (17/166); RR 1.28 (95% CI 0.71-2.32), p=0.42]. There is no evidence of significant difference on the clinical pregnancy rate when endometrial scratching during hysteroscopy is compared to only hysteroscopy in women undergoing IUI.

Background and Purpose: The aim of the current study is to review the clinical features, surgery outcomes and parental satisfaction of children with destructive encephalopathy who underwent epilepsy surgery due to medically intractable seizures. Methods: 48 patients who underwent epilepsy surgery from October 2003 to August 2011 at Severance Children’s Hospital have been reviewed. The survey was conducted for functional outcomes and parental satisfaction at least 1 year after the surgery. Results: Epileptic encephalopathy including Lennox-Gastaut syndrome and infantile spasms was more prevalent than symptomatic focal epilepsy. Hypoxic ischemic injury accounted for most of the underlying etiology of the destructive encephalpathy, followed by central nervous system infection and head trauma. 27 patients (56.3%) underwent resective surgery and 21 patients (43.7%) underwent palliative surgery. 16 patients (33.3%) achieved seizure free and 27 parents (87.5%) reported satisfaction with the outcome of their children’s epilepsy surgery. In addition, 14 parents (77.8 %) whose children were not seizure free reported satisfaction with their children’s improvement in cognitive and behavior issues. Conclusions: Epilepsy surgery in destructive encephalopathy was effective for controlling seizures. Parents reported satisfaction not only with the surgical outcomes, but also with improvement of cognitive and behavior issues. PMID:24649473

Objective: This study was conducted to research the factors determining biochemical recurrence (BCR) in low-risk localized prostate cancer patients who underwent radical prostatectomy (RP). Materials and methods: We retrospectively analyzed the data of 504 patients who had undergone RP between 2003 and 2013 at our clinic. One hundred and fifty-two patients who underwent RP for low-risk prostate cancer were included in the study. Results: The mean follow-up period for patients was 58.7 (21–229) months. The mean age of the patients was 63.7±7.2 years (49–79). The mean prostate specific antigen (PSA) value was 5.25±4.22 ng/mL (3.58–9.45). The BCR rate after the operation was 25% (38/152). In the univariate analysis, recurrence determining factors were shown to include extracapsular involvement (ECI) (p=0.004), capsular invasion (CI) (p=0.001), age (p=0.014), and tumor size (p=0.006). However, only CI was found to be significant in multivariate analysis (p=0.001). Conclusion: Capsular invasion is an independent risk factor in low-risk prostate cancer patients who underwent RP for BCR. PMID:26328203

Lower extremity wounds present a major clinical challenge. This paper introduces a new multistep approach for improved aesthetic and functional outcome for lower extremity wound closure after Mohs micrographic surgery. In this prospective case series, 12 consecutive patients undergoing Mohs micrographic surgery for cutaneous malignancies of the lower extremities underwent closure assisted by elastic bandages, proper positioning with 45° flexion of the knee, buried vertical mattress sutures, and careful eversion, using a premium angled stapler. Assessment of cosmetic outcome was performed by 2 blinded observers, using the Hollander Wound Evaluation Scale. The mean age was 73 ± 9 years with most patients having at least one comorbidity. Six patients (50%) underwent resection of a basal cell carcinoma and 5 patients (42%) underwent resection of a squamous cell carcinoma and 1 patient (8%) underwent resection of a keratoacanthomatous carcinoma. There were no wound complications, and at the 3- to 6-month follow-up, 11 of the 12 wounds (92%) had an optimal Hollander Wound Evaluation Scale score of 6. This new approach to lower extremity wounds provides excellent cosmetic outcome with no reported complications.

Early refeeding after nonvariceal upper gastrointestinal bleeding is safe and reduces hospital stay/costs. The aim of this study was obtaining objective data on refeeding after nonvariceal upper gastrointestinal bleeding. From 1 year span records of nonvariceal upper gastrointestinal bleeding patients that underwent urgent endoscopy: clinical features; rockall score; endoscopic data, including severity of lesions and therapy; feeding related records of seven days: liquid diet prescription, first liquid intake, soft/solid diet prescription, first soft/solid intake. From 133 patients (84 men) Rockall classification was possible in 126: 76 score ≥5, 50 score <5. One persistent bleeding, eight rebled, two underwent surgery, 13 died. Ulcer was the major bleeding cause, 63 patients underwent endoscopic therapy. There was 142/532 possible refeeding records, no record 37% patients. Only 16% were fed during the first day and half were only fed on third day or later. Rockall <5 patients started oral diet sooner than Rockall ≥5. Patients that underwent endoscopic therapy were refed earlier than those without endotherapy. Most feeding records are missing. Data reveals delayed refeeding, especially in patients with low-risk lesions who should have been fed immediately. Nonvariceal upper gastrointestinal bleeding patients must be refed earlier, according to guidelines.

The aims of this study were to evaluate the prevalence and the clinical predictors of dysphagia and to determine the characteristics of videofluoroscopic swallowing study findings in infants after open heart procedures. This study is a retrospective review of 146 infants who underwent open heart surgery. The infants with dysphagia were compared with those without dysphagia. The videofluoroscopic swallowing study findings of the infants with dysphagia were also evaluated. Of the 146 infants who underwent open heart surgery, 35 (24.0%) had dysphagia symptoms. The infants with dysphagia had lower body weight at operation, more malformation syndromes, longer operation times, and more complex operations than did the infants without dysphagia. In addition, the infants with dysphagia required more time to achieve full oral feeding and had longer hospital stays. Thirty-three infants underwent videofluoroscopic swallowing study: 32 (97.0%) exhibited at least one abnormal finding among the videofluoroscopic swallowing study parameters and 21 (63.6%) exhibited tracheal aspiration. Given the high rate of aspiration in the infants who underwent open heart procedures, monitoring and prompt recognition of the signs and the risk factors of dysphagia may substantially improve infant care with oral feeding and reduce the duration of hospital stays.

The aim of the study was a retrospective analysis of the medical records of patients who underwent surgery due to deep infiltrating rectovaginal endometriosis (mainly with the use of the 'shaving' technique). We analysed 160 cases of patients who underwent surgery due to the deep infiltrating rectovaginal endometriosis in our ward between 2003-2014. Depending on lesion localization, disease severity and clinical characteristics, three possible ways of operation were proposed: laparoscopic, vaginal or a combined vagino-laparoscopic approach. A total of 120 patients underwent laparoscopic removal of the endometrial lesions, whereas 17 were operated vaginally and 23 with the use of the combined approach. Nodule resection was successfully performed in all cases. The combined vagino-laparoscopic operations were characterized by the longest operating time. The rate of perioperative complications was low in the group of patients who underwent laparoscopic or combined operations. The necessity of bowel wall suturing occurred in 15 cases. This procedure was performed in order to strengthen the bowel wall (in cases when no perforation occurred) or due to bowel resection during surgery. Unexpected bowel perforation occurred in only 5 cases. Conclusions: Vaginal, laparoscopic and the combined vagino-laparoscopic surgeries can be safely performed in cases of deep rectovaginal endometriosis.

Abstract Objective To compare medical abortion practised at home and in clinics in terms of effectiveness, safety and acceptability. Methods A systematic search for randomized controlled trials and prospective cohort studies comparing home-based and clinic-based medical abortion was conducted. The Cochrane Central Register of Controlled Trials, EMBASE, MEDLINE and Popline were searched. Failure to abort completely, side-effects and acceptability were the main outcomes of interest. Odds ratios and their 95% confidence intervals (CIs) were calculated. Estimates were pooled using a random-effects model. Findings Nine studies met the inclusion criteria (n = 4522 participants). All were prospective cohort studies that used mifepristone and misoprostol to induce abortion. Complete abortion was achieved by 86–97% of the women who underwent home-based abortion (n = 3478) and by 80–99% of those who underwent clinic-based abortion (n = 1044). Pooled analyses from all studies revealed no difference in complete abortion rates between groups (odds ratio = 0.8; 95% CI: 0.5–1.5). Serious complications from abortion were rare. Pain and vomiting lasted 0.3 days longer among women who took misoprostol at home rather than in clinic. Women who chose home-based medical abortion were more likely to be satisfied, to choose the method again and to recommend it to a friend than women who opted for medical abortion in a clinic. Conclusion Home-based abortion is safe under the conditions in place in the included studies. Prospective cohort studies have shown no differences in effectiveness or acceptability between home-based and clinic-based medical abortion across countries. PMID:21556304

Oral cavity carcinoma is the most common cancer in Indian population. Metastatic nodal disease is the most important prognostic factor for oral cancers. In head and neck cancers with clinically N0 neck, standard selective neck dissection is performed by protecting the spinal accessory nerve to remove level IIA & IIB lymph nodes. The purpose of this study was to analyze the significance of level IIB dissection in patients of oral cavity cancer who underwent primary surgery with functional neck dissection. Two hundred ten patients with clinically N0 neck underwent neck dissection, where level IIB lymph nodes were dissected, labelled and processed separately. Among 210 patients of clinically N0 neck, 168 patients were pathologically N0 (80 %). Out of remaining 42 (20 %), 36 (17.14 %) were pN1 and 6 (2.86 %) were pN2. Among those with pN1 (36), level IB was involved in 24 patients (66.67 %) and level IIA was involved in 12 patients (33.33 %). Only 2 patients had involvement of level IIB lymph nodes. Among 6 patients of pN2 disease, 4 patients had simultaneous involvement of level IB and level IIA lymph nodes. Remaining 2 patients had isolated involvement of level III lymph nodes. Thus only 2 patients (< 1 %) out of 210 clinically N0 oral squamous cell carcinoma showed level IIB lymph node involvement. Thus we conclude that a frozen section of level 2a is advisable to decide the need for level 2b node dissection in clinically N0 neck as the sensitivity of clinical evaluation is extremely low.

Glioblastoma multiforme is the most common primary brain tumor, despite an aggressive clinical course, less than 2% of patients develop extraneural metastasis. We present a 72-year-old male diagnosed with a right temporal glioblastoma due to headache. He underwent total gross resection surgery and after that the patient was treated with adyuvant therapy. Five months after the patient returned with trigeminal neuralgia, and MRI showed an infratemporal cranial mass which infiltrates masticator space, the surrounding bone, the temporal muscle and superior cervical and parotid lymph nodes. The patient underwent a new surgery reaching partial resection of the temporal lesion. After that the patient continued suffering from disabling trigeminal neuralgia, that's why because of the bad clinical situation and the treatment failure we decided to restrict therapeutic efforts. The patient died 3 weeks after the diagnosis of extracranial metastasis. Copyright © 2018 Sociedad Española de Neurocirugía. Publicado por Elsevier España, S.L.U. All rights reserved.

The aim of this study was to compare periorbital edema and ecchymosis seen after closed (endonasal) and open (external) septorhinoplasty (SRP). In total, 50 patients undergoing hump extraction and osteotomies were allocated to 2 groups. Group 1 consisted of 25 patients who underwent closed SRP. Group 2 consisted of 25 patients who underwent open SRP. Operation time, amount of intraoperative bleeding, and complications were recorded. Scoring of eyelid edema and periorbital ecchymosis was evaluated on the first, third, and seventh postoperative days using a scale of 0 to 4 by the first author. There was no statistically significant difference between the groups in terms of age, sex, or operation time. No significant difference was observed clinically or statistically in the scores of periorbital edema or ecchymosis between groups 1 and 2 on the first, third, and seventh postoperative days (P > 0.05). The authors observed no clinically or statistically significant difference in comparing periorbital edema and ecchymosis seen after closed and open SRP.

Adhesions small bowel obstructions (aSBO) are among the leading causes of emergency operative intervention. About the 80% of aSBO cases resolve without a surgical treatment. It's important to identify which patients could undergo a conservative treatment to prevent an useless surgery The aim of this study is to determine findings that can indicate whether patients with aSBO should undergo a conservative or a surgical treatment. 313 patients with diagnosis of submission of aSBO were restudied. Patients were divided into two groups based on the different type of treatment received, 225 patients who underwent surgical treatment within 24 hours after admission, 88 patients which underwent conservative treatment successfully. For each patient, clinical, hematochemical and radiological findings have been analysed. The treatment of aSBO should be, at the beginning, conservative except that cases that presents clinical and/or CT-scan findings predictive for a surgical treatment (free peritoneal fluid, mesenterial edema, transitional point) or a peritonitis (pneumatosis intestinalis, pneumoperitoneum).

The etiology of chronic subdural hematoma (CSDH) in patients is diverse. The primary objective of this article was to discuss one of the causes, spontaneous intracranial hypotension with spinal cerebrospinal fluid (CSF) leak, which is usually neglected by the neurosurgeon. All the consecutive 15 patients who underwent operation for CSDHs between June 2012 and June 2014 at Sir Run Run Shaw Hospital of Zhejiang University were included in this retrospective cohort study. The clinical and imaging data of these patients with CSDHs due to spinal CSF leak were retrospectively studied. Fifteen patients, with a mean age of 53.8 ± 8.3 years, underwent operations for CSDH. Hematomas were unilateral in 4 patients and bilateral in 11 patients. Among these patients, eight patients had recurrence of hematomas after operation due to neglect of spinal CSF leak. All patients had fully recovery. Spinal CSF leak is a cause of cSDH, which is overlooked by the doctor.

Both human and animal studies have suggested that oxytocin may have therapeutic potential in the treatment of schizophrenia. We evaluated the effects of intranasal oxytocin on cognition and its predictive factors in Japanese patients with schizophrenia. Subjects were 16 chronic schizophrenia patients who underwent intranasal oxytocin treatment for 3 months and were assessed for changes in severity of clinical symptoms and cognitions. Fifteen of the 16 subjects underwent 3-Tesla magnetic resonance imaging. Oxytocin significantly reduced scores on the positive and negative syndrome scale, especially on the negative symptoms. As for cognition, there was an improvement of the verbal fluency. Furthermore, the change of the negative score in positive and negative syndrome scale showed a negative correlation with the gray matter volumes of the right insula and left cingulate cortex. Our results indicate that daily administration of intranasal oxytocin may be effective for ameliorating clinical symptoms and cognitive functions in chronic schizophrenia patients, and this improvement may be related to the gray matter volume of the right insula and left cingulate cortex.

This study reports the clinical outcomes of head and neck adenoid cystic carcinoma treatment over a 20-year period. The treatment outcome of 51 head and neck adenoid cystic carcinoma patients treated between 1992 and 2013 were analysed. Patients were stratified into radical treatment and disease control groups. A total of 40 patients underwent surgery and post-operative radiotherapy. The 10-year disease-specific survival rate was 93 per cent. Eleven patients had tumour recurrence: of these, nine were pulmonary metastases. The 11 patients in the disease control group had a median follow up of 21 months (range, 2-172 months); 5 underwent radical radiotherapy with palliative intent. There was late tumour recurrence in over 25 per cent of patients. Adenoid cystic carcinoma has a high tendency to relapse even after radical excision and adjuvant therapy. However, definitive radiotherapy should still be considered on an individual basis because it may provide local control and prolong patient survival.
