While advanced diagnostic imaging is a large contributor to the growth in health care costs, direct-access to physical therapy is associated with decreased rates of diagnostic imaging. No study has systematically evaluated with evidence-based criteria the appropriateness of advanced diagnostic imaging, including magnetic resonance imaging (MRI), when ordered by physical therapists. The primary purpose of this study was to describe the appropriateness of magnetic resonance imaging (MRI) or magnetic resonance arthrogram (MRA) exams ordered by physical therapists in a direct-access sports physical therapy clinic. Retrospective observational study of practice. Greater than 80% of advanced diagnostic imaging orders would have an American College of Radiology (ACR) Appropriateness Criteria rating of greater than 6, indicating an imaging order that is usually appropriate. A 2-year retrospective analysis identified 108 MRI/MRA examination orders from four physical therapists. A board-certified radiologist determined the appropriateness of each order based on ACR appropriateness criteria. The principal investigator and co-investigator radiologist assessed agreement between the clinical diagnosis and MRI/surgical findings. Knee (31%) and shoulder (25%) injuries were the most common. Overall, 55% of injuries were acute. The mean ACR rating was 7.7; scores from six to nine have been considered appropriate orders and higher ratings are better. The percentage of orders complying with ACR appropriateness criteria was 83.2%. Physical therapist's clinical diagnosis was confirmed by MRI/MRA findings in 64.8% of cases and was confirmed by surgical findings in 90% of cases. Physical therapists providing musculoskeletal primary care in a direct-access sports physical therapy clinic appropriately ordered advanced diagnostic imaging in over 80% of cases. Future research should prospectively compare physical therapist appropriateness and utilization to other groups of providers and

The assessment of dermatology undergraduates is being done through computer assisted objective structured clinical examination at our institution for the last 4 years. We attempted to compare objective structured clinical examination (OSCE) and computer assisted objective structured clinical examination (CA-OSCE) as assessment tools. To assess the relative effectiveness of CA-OSCE and OSCE as assessment tools for undergraduate dermatology trainees. Students underwent CA-OSCE as well as OSCE-based evaluation of equal weightage as an end of posting assessment. The attendance as well as the marks in both the examination formats were meticulously recorded and statistically analyzed using SPSS version 20.0. Intercooled Stata V9.0 was used to assess the reliability and internal consistency of the examinations conducted. Feedback from both students and examiners was also recorded. The mean attendance for the study group was 77% ± 12.0%. The average score on CA- OSCE and OSCE was 47.4% ± 19.8% and 53.5% ± 18%, respectively. These scores showed a mutually positive correlation, with Spearman's coefficient being 0.593. Spearman's rank correlation coefficient between attendance scores and assessment score was 0.485 for OSCE and 0.451 for CA-OSCE. The Cronbach's alpha coefficient for all the tests ranged from 0.76 to 0.87 indicating high reliability. The comparison was based on a single batch of 139 students. Such an evaluation on more students in larger number of batches over successive years could help throw more light on the subject. Computer assisted objective structured clinical examination was found to be a valid, reliable and effective format for dermatology assessment, being rated as the preferred format by examiners.

Interactive Metronome (IM, The Interactive Metronome Company, Sunrise, Florida, USA) is a computer-based modality marketed to rehabilitation professionals who want to improve outcomes in areas of coordination, motor skills, self-regulation behaviors, and cognitive skills. This retrospective study examined the efficacy of IM training on improving timing skills, hand function, and parental report of self-regulatory behaviors. Forty eight children with mixed motor and cognitive diagnoses completed an average of 14 one-hour training sessions over an average of 8.5 weeks in an outpatient setting. Each child was assessed before and after training with the Interactive Metronome Long Form Assessment, the Jebsen Taylor Test of Hand Function, and a parent questionnaire. All three measures improved with statistical significance despite participants having no direct skill training. These results suggest an intimate relationship between cognition and motor skills that has potential therapeutic value. Level 4, Retrospective Case Series. Copyright © 2015 Hanley & Belfus.

In a prospective series of 72 patients, clinical and ultrasonographic examination of the thyroid gland were compared in detail. Normal-sized lobes were differentiated from enlarged ones both by inspection and by palpation. When lobar size was assessed by palpation, the estimate was most clearly influenced by increase in width. The correlation between two examiners in lobe size assessment was significant. In the classification of thyroid disease as diffuse, solitary, or multinodular, clinical examination and ultrasonography correlated significantly. However, only one third of the clinically solitary nodules proved to be solitary by ultrasound examination. Of 77 separate nodules, 43 escaped detection on clinical examination. Of these 43, 14 nodules exceeded 2 cm in diameter. It is concluded that the use of ultrasonography frequently alters the primary evaluation of thyroid nodularity based on palpation.

'Rumours' and clinical trials: a retrospective examination of a paediatric malnutrition study in Zambia, southern Africa

Background Many public health researchers conducting studies in resource-constrained settings have experienced negative 'rumours' about their work; in some cases they have been reported to create serious challenges and derail studies. However, what may appear superficially as 'gossip' or 'rumours' can also be regarded and understood as metaphors which represent local concerns. For researchers unaccustomed to having concerns expressed from participants in this manner, possible reactions can be to be unduly perturbed or conversely dismissive. This paper represents a retrospective examination of a malnutrition study conducted by an international team of researchers in Zambia, Southern Africa. The fears of mothers whose children were involved in the study and some of the concerns which were expressed as rumours are also presented. This paper argues that there is an underlying logic to these anxieties and to dismiss them simply as 'rumours' or 'gossip' would be to overlook the historic and socio-economic factors which have contributed to their production. Methods Qualitative interviews were conducted with the mothers whose children were involved in the study and with the research nurses. Twenty five face-to-face interviews and 2 focus group discussions (FGDs) were conducted with mothers. In addition, face-to-face interviews were conducted with research nurses participating in the trial. Results A prominent anxiety expressed as rumours by the mothers whose children were involved in the study was that recruitment into the trial was an indicator that the child was HIV-infected. Other anxieties included that the trial was a disguise for witchcraft or Satanism and that the children's body parts would be removed and sold. In addition, the liquid, milk-based food given to the children to improve their nutrition was suspected of being insufficiently nutritious, thus worsening their condition.

The purpose of this study was to determine clinical and ultrasonographic characteristics of male breast tumors. The medical records of male patients with breast lesions were retrieved from an electronic medical record database and a pathology database and retrospectively reviewed. A total of 112 men (125 breast masses) with preoperative breast ultrasonography (US) were included (median age, 59.50 years; age range, 15-96 years). Data extracted included patient age, if the lesions were bilateral, palpable, and tender, and the presence of nipple discharge. Breast lesion features on static US images were reviewed by three experienced radiologists without knowledge of physical examination or pathology results, original breast US image interpretations, or surgical outcomes. The US features were documented according to the BI-RADS (Breast Imaging-Reporting and Data System) US lexicons. A forth radiologist compiled the data for analysis. Of the 125 breast masses, palpable tender lumps and bilateral synchronous masses were more likely to be benign than malignant (both, 100% vs 0%, P < 0.05). Advanced age and bloody discharge from nipples were common in malignant lesions (P <0.05). A mass eccentric to a nipple, irregular shape, the presence of an echogenic halo, predominantly internal vascularity, and rich color flow signal on color Doppler ultrasound were significantly related to malignancy (all, P < 0.05). An echogenic halo and the presence of rich color flow signal were independent predictors of malignancy. Specific clinical and US characteristics of male breast tumors may help guide treatment, and determine if surgery or conservative treatment is preferable.

2018-01-01

The aim of this study was to retrospectively investigate the development of a model-based, computer-assisted training approach for performing and charting periodontal examinations in a dental clinic in Germany. The study was initiated in summer semester 2013 and repeated in two consecutive semesters (S1: 44 students, S2: 48 students, and S3: 61 students) because technical features were introduced (S2: feedback and time control; S3: input control). In each semester, new dental students who had never performed periodontal examinations participated. Students were divided into two groups and received intense training at different time points. Agreement levels were calculated at baseline, after the first group received training, and after the second group received training. Comparisons were also made among the semesters. All 153 enrolled students in the three semesters participated. The results showed that probing depth accuracy significantly decreased in S1 from baseline to training completion (79.9% to 74.5%), and the probing depth accuracy significantly increased in S2 (76.1% to 78.9%) and S3 (77.2% to 82.3%). The students who received intense training at a late stage of the tutorial showed greater improvement, especially in the case of S3. Small changes in accuracy were observed for recession (S1: 94.5% to 96.1%; S2: 93.8% to 93.9%; S3: 95.4% to 96.6%). Accuracy for furcation involvement improved significantly in S1 (46.1% to 52.0%), S2 (46.8% to 59.7%), and S3 (44.2% to 58.3%); the improvements occurred when the students received intense training. The time taken for periodontal examination decreased significantly for S2 (23.6 to 14.2 min) and S3 (25.7 to 13.9 min). This study found that when feedback was provided, the students' periodontal examinations improved in accuracy and duration.

This study aims to assess and compare objective and subjective scores of empathy in final-year medical students by using firstly a validated student self-assessment just prior to the psychiatry objective structured clinical examination (OSCE), and then comparing this to clinical examiner's and simulated patient's (SP's) assessments of empathy of students using a Global Rating of Empathy scale (GRE) during a psychiatry OSCE. In 2011, all final-year medical students in the University College Dublin were invited to complete a subjective, self-assessed empathy questionnaire (The Jefferson scale of physician empathy-student version (JSPE-S)). They were also assessed for empathy in four OSCEs by the clinical examiner and the SP acting in that OSCE scenario. Included in the analysis were 163 of 184 final-year students JSPE-S (88.6%) questionnaires. The female students scores on the JSPE-S were significantly higher than those of their male peers (t=3.34, p=0.001). Concurrent validity was greater between the SPs' assessments of empathy in the OSCE and the JSPE-S score than between the clinical examiners assessments of empathy and the JSPE-S score (r=0.23, p<0.005; r=0.14, p<0.08). Inter-rater reliability of SP's and clinical examiner's using the GRE was found to be high (F=0.868 (df=171, 171), p value<0.001). SPs may be valid assessors of empathy in medical students during an OSCE.

There is very little published work on the visual needs of homeless people. This paper is the first study to investigate the visual needs of homeless people in the UK. Although similar work has been done in other countries, this study is unique because the United Kingdom is the only country with a National Health Service which provides free healthcare at the point of access. This study analysed the refractive status of the sample used, determined the demographics of homeless people seeking eye care and established if there is a need for community eye health with access to free spectacle correction in East London. This retrospective case study analysed the clinical records of 1,141 homeless people using the Vision Care for Homeless People services at one of their clinics in East London. All eye examinations were carried out by qualified optometrists and, where appropriate, spectacles were dispensed to patients. Data captured included age, gender, ethnicity and refractive error. Results were analysed using two-sample t-tests with Excel and Minitab. Demographics of age, gender and ethnicity are described. Spherical equivalents (SE) were calculated from prescription data available for 841 clinic users. Emmetropia was defined as SE-0.50DS to +1DS, myopia as SE < -0.50DS, and hyperopia as SE > +1DS. The majority of clinic users were male (79.2 %, n = 923). Approximately 80 % (n = 583) of clinic users were white, 10 % (n = 72) were 'black', 4 % (n = 29) 'Asian' and the remaining 5.6 % (n = 40) were of 'mixed ethnicity' and 'other' groups. The mean age of females attending the clinic was significantly lower than that of males (45.9 years, SD = 13.8 vs' 48.4 years, SD = 11.8) when analysed using a two-sample t-test (t (317) = 2.44, p = 0.02). One third of service users were aged between 50-59 years. Myopia and hyperopia prevalence rates were 37.0 % and 21.0 % respectively. A total of 34.8 % of homeless people were found

2016-01-01

The objective of this study was to evaluate the concordance between clinical symptoms, Doppler ultrasound (US), and shunt venography for the detection of stent-graft transjugular intrahepatic portosystemic shunt (TIPS) dysfunction. Forty-one patients (M:F 30:11, median age 55 years) who underwent contemporaneous clinical exam, Doppler US, and TIPS venography between 2003 and 2014 were retrospectively studied. Clinical symptoms (recurrent ascites or variceal bleeding) were dichotomously classified as present/absent, and US and TIPS venograms were categorized in a binary fashion as normal/abnormal. US abnormalities included high/low (>190 or <90 cm/s) TIPS velocity, significant velocity rise/fall (>50 cm/s), absent flow, and return of antegrade intra-hepatic portal flow. Venographic abnormalities included shunt stenosis/occlusion and/or pressure gradient elevation. Clinical and imaging concordance rates were calculated. Fifty-two corresponding US examinations and venograms were assessed. The median time between studies was 3 days. Forty of 52 (77%) patients were symptomatic, 33/52 (64%) US examinations were abnormal, and 20/52 (38%) TIPS venograms were abnormal. Concordance between clinical symptoms and TIPS venography was 48% (25/52), while the agreement between US and shunt venography was 65% (34/52). Clinical symptoms and the US concurred in 60% (31/52) of the patients. The sensitivity of clinical symptoms and US for the detection of venographically abnormal shunts was 80% (16/20) and 85% (17/20), respectively. Both clinical symptoms and the US had low specificity (25%, 8/32 and 50%, 16/32) for venographically abnormal shunts. Clinical findings and the US had low concordance rates with TIPS venography, with acceptable sensitivity but poor specificity. These findings suggest the need for improved noninvasive imaging methods for stent-graft TIPS surveillance.

To provide descriptive information about history-taking (HX) and physical examination (PE) performance for U.S. medical students as documented by standardized patients (SPs) during the Step 2 Clinical Skills (CS) component of the United States Medical Licensing Examination. The authors examined two hypotheses: (1) Students perform worse in PE compared with HX, and (2) for PE, students perform worse in the musculoskeletal system and neurology compared with other clinical domains. The sample included 121,767 student-SP encounters based on 29,442 examinees from U.S. medical schools who took Step 2 CS for the first time in 2011. The encounters comprised 107 clinical presentations, each categorized into one of five clinical domains: cardiovascular, gastrointestinal, musculoskeletal, neurological, and respiratory. The authors compared mean percent-correct scores for HX and PE via a one-tailed paired-samples t test and examined mean score differences by clinical domain using analysis of variance techniques. Average PE scores (59.6%) were significantly lower than average HX scores (78.1%). The range of scores for PE (51.4%-72.7%) was larger than for HX (74.4%-81.0%), and the standard deviation for PE scores (28.3) was twice as large as the HX standard deviation (14.7). PE performance was significantly weaker for musculoskeletal and neurological encounters compared with other encounters. U.S. medical students perform worse on PE than HX; PE performance was weakest in musculoskeletal and neurology clinical domains. Findings may reflect imbalances in U.S. medical education, but more research is needed to fully understand the relationships among PE instruction, assessment, and proficiency.

A retrospective cohort study was performed evaluating all children who underwent esophagoscopy for suspected foreign body ingestion at our institution from 2006 to 2013. Five hundred forty-three patients were included (54% male). Average age was 4.7 years (SD = 4.1 years). Foreign bodies were identified on esophagoscopy in 497 cases (92%). Ingestion was witnessed in 23% of cases. Most common presenting symptoms were choking/gagging (49%), vomiting (47%), and dysphagia/odynophagia (42%). Most patients with foreign bodies had a normal exam (76%). Most foreign bodies were radiopaque (83%). In 59% of patients with normal chest radiographs, a foreign body was present. Sensitivity and specificity of 1 or more findings on history, physical examination, and imaging were 99% and 0%, 21% and 76%, and 83% and 100%, respectively. Most patients with esophageal foreign bodies are symptomatic. Although many patients will have a normal physical examination, an abnormal exam should increase suspicion for a foreign body. Most esophageal foreign bodies are radiopaque, but a normal chest radiograph cannot rule out a foreign body. © The Author(s) 2015.

Objective As a result of a curriculum reform launched in 2012 at our institution, preclinical training was shortened to 2 years instead of the traditional 3 years, creating additional incentives to optimise teaching methods. In accordance with the new curriculum, a semester-long preclinical module of clinical skills (CS) laboratory training takes place in the second year of study, while an introductory clinical course (ie, brief introductory clerkships) is scheduled for the Fall semester of the third year. Objective structured clinical examinations (OSCEs) are carried out at the conclusion of both the preclinical module and the introductory clinical course. Our aim was to compare the scores at physical examination stations between the first and second matriculating classes of a newly reformed curriculum on preclinical second-year OSCEs and early clinical third-year OSCEs. Design Analysis of routinely collected data. Setting One Polish medical school. Participants Complete OSCE records for 462 second-year students and 445 third-year students. Outcome measures OSCE scores by matriculation year. Results In comparison to the first class of the newly reformed curriculum, significantly higher (ie, better) OSCE scores were observed for those students who matriculated in 2013, a year after implementing the reformed curriculum. This finding was consistent for both second-year and third-year cohorts. Additionally, the magnitude of the improvement in median third-year OSCE scores was proportional to the corresponding advancement in preceding second-year preclinical OSCE scores for each of two different sets of physical examination tasks. In contrast, no significant difference was noted between the academic years in the ability to interpret laboratory data or ECG — tasks which had not been included in the second-year preclinical training. Conclusion Our results suggest the importance of preclinical training in a CS laboratory to improve students’ competence in

The purpose of this study was to examine the validity of this practice. This was a retrospective cohort study of medical students at the Virginia Commonwealth University School of Medicine who completed clerkships in 2012 through 2014. Linear regression was used to determine how well United States Medical Licensing Examination Step 1 scores predicted Subject Examination scores in seven clerkships. The authors then substituted each student's Subject Examination standard scores with his or her Step 1 standard score. Clerkship grades based on the Step 1 substitution were compared with actual grades with the Wilcoxon rank test. A total of 2,777 Subject Examination scores from 432 students were included in the analysis. Step 1 scores significantly predicted between 23% and 44% of the variance in Subject Examination scores, P < .001 for all clerkship regression equations. Mean differences between expected and actual Subject Examination scores were small (≤ 0.2 points). There was a match between 73% of Step 1 substituted final clerkship grades and actual final clerkship grades. The results of this study suggest that performance on Step 1 can be used to identify and counsel students at risk for poor performance on the Subject Examinations. In addition, these findings call into the question the validity of using scores from Subject Examinations as a high-stakes assessment of learning in individual clerkships.

To assess the utility of an MRI-compatible incubator (INC) by comparing. In a retrospective study, the clinical and radiological aspects of 129 neonatal MRI examinations during a 3 year period were analyzed. Routine protocols including fast spin-echo T2-weighted (w) sequences, axial T1w, Gradient-echo, diffusion sequences, and 3D T1 gradient-echo sequences were performed routinely, angiography and spectroscopy were added in some cases. Diffusion-tensor imaging was done in 50% of the babies examined in the INC and 26% without INC. Sequences, adapted from fetal MR-protocols were done in infants younger than 32 gestational weeks. Benefit from MR-information with respect to further management was evaluated. The number of the examinations increased (30-99), while the mean age (43-38, 8 weeks of gestational age) and weight (3308-2766 g) decreased significantly with the use of the MR-compatible incubator. The mean imaging time (34, 43-30, 29 min) decreased, with a mean of one additionally performed sequence in the INC group. All infants received sedatives according to our anaesthetic protocol preceding imaging, but a repeated dose was never necessary (10% without INC) using the INC. Regarding all cases, MR-based changes in clinical management were initiated in 58%, while in 57% of cases the initial ultrasound diagnosis was changed or further specified. The use of the INC enables the MR access of unstable infants with suspect CNS problems to the management, of whom is improved by MR information to significantly higher percentage, than without INC.

This study analyzes the clinical characteristics of the brain metastasis (BM) of gynecologic cancer based on the type of cancer. In addition, the study examines the factors influencing the survival. Total 61 BM patients of gynecologic cancer were analyzed retrospectively from January 2000 to December 2012 in terms of clinical and radiological characteristics by using medical and radiological records from three university hospitals. There were 19 (31.1%) uterine cancers, 32 (52.5%) ovarian cancers, and 10 (16.4%) cervical cancers. The mean interval to BM was 25.4 months (21.6 months in ovarian cancer, 27.8 months in uterine cancer, and 33.1 months in cervical cancer). The mean survival from BM was 16.7 months (14.1 months in ovarian cancer, 23.3 months in uterine cancer, and 8.8 months in cervical cancer). According to a multivariate analysis of factors influencing survival, type of primary cancer, Karnofsky performance score, status of primary cancer, recursive partitioning analysis class, and treatment modality, particularly combined therapies, were significantly related to the overall survival. These results suggest that, in addition to traditional prognostic factors in BM, multiple treatment methods such as neurosurgery and combined chemoradiotherapy may play an important role in prolonging the survival for BM patients of gynecologic cancer.

The aim of this retrospective clinical study was to evaluate the location and treatment of second canals in mesiobuccal roots (MB2) of first and second maxillary molars in a predoctoral endodontic clinic by the graduating classes of 2008 to 2015. These results were compared to similar clinical studies. Included in the study were 368 root canal treatments performed by 310 third- and fourth-year dental students at one U.S. dental school. All cases were done under faculty supervision, and the students were instructed to use dental loupe magnification. Students' evaluation sheets were used to deteremine the total MB2 canals treated in first and second maxillary molars. The results showed that, overall, 72.55% of the teeth had an MB2 canal treated. The frequency was higher in first molars (75.91%) than in second molars (56.92%) (p<0.05). Third-year students were able to detect 39 MB2 canals in 57 maxillary molars (68.42%), while fourth-year students detected 228 MB2 canals in 311 teeth (73.31%) (p>0.05). Under proper supervision by experienced endodontists, these dental students were capable of treating MB2 canals in maxillary molars. The frequency of MB2 canals located and treated by dental students with the assistance of experienced professionals was higher in first than in second molars. No significant difference was found between third- and fourth-year students. The incidence of MB2 canals located and treated in this study was found to be similar to that in other clinical studies.

We present a retrospective clinical study of 18 cases of new daily persistent headache (NDPH), a rare chronic headache, included in the fourth chapter of the II IHS classification; the pathophysiology of NDPH is unknown but a link with viral infections (especially Epstein-Barr virus (EBV)) has been suggested. Comparing our series with the other two published until now, we did not find any particular difference, as regards to clinical aspects. However, our laboratory tests show a recent herpes simplex virus infection in 42% and cytomegalovirus in 11% of cases; moreover we could not find any EBV infection. Our data suggest that viruses other than EBV can play a role in NDPH.

For early detection of developmental dysplasia of the hip (DDH), neonatal hip screening using clinical examination and/or ultrasound has been recommended. Although there have been many studies on the reliability of both screening techniques, there is still controversy in the screening strategies; clinical vs. selective or universal ultrasound screening. To determine the screening strategy, we assessed the agreement among the methods; clinical examination by an experienced pediatric orthopedic surgeon, sonographic morphology, and sonographic stability. From January 2004 to June 2009, a single experienced pediatric orthopedic surgeon performed clinical hip screenings for 2,686 infants in the neonatal unit and 43 infants who were referred due to impressions of hip dysplasia before 3 months of age. Among them, 156 clinically unstable or high-risk babies selectively received bilateral hip ultrasound examinations performed by the same surgeon using the modified Graf method. The results were analyzed statistically to detect any correlations between the clinical and sonographic findings. Although a single experienced orthopedic surgeon conducted all examinations, we detected only a limited relationship between the results of clinical and ultrasound examinations. Ninety-three percent of the clinically subluxatable hips were normal or immature based on static ultrasound examination, and 74% of dislocating hips and 67% of limited abduction hips presented with the morphology below Graf IIa. A total of 80% of clinically subluxatable, 42% of dislocating and 67% of limited abduction hips appeared stable or exhibited minor instability on dynamic ultrasound examination. About 7% of clinically normal hips were abnormal upon ultrasound examination; 5% showed major instability and 3% showed dysplasia above Graf IIc. Clinical stability had small coefficients between ultrasound examinations; 0.39 for sonographic stability and 0.37 for sonographic morphology. Between sonographic

The study evaluated which viruses can be detected in dogs with acute hemorrhagic diarrhea and compared signalment, clinical signs, and laboratory abnormalities among groups of dogs infected with different viruses and those that tested virus-negative. Fecal samples from 935 dogs with acute hemorrhagic diarrhea were examined by electron microscopy. The medical records of these patients were retrospectively evaluated for clinical and laboratory parameters. Virus was detected in 44.2% of the dogs presented with acute bloody diarrhea. The highest prevalence for a virus infection was demonstrated for canine parvovirus (19.9%), followed by coronavirus (17.3%), and paramyxovirus (13.9%). More than one virus species was detected in 6.5% of all fecal samples. Dogs with a virus-positive fecal sample were significantly younger than dogs that tested negative on electron microscopy. Among virus-positive dogs, dogs with parvovirus infection were significantly younger when compared to dogs infected with other enteric viruses. Parvovirus-infected patients also showed significantly lower leukocyte and erythrocyte counts as well as hematocrit, total protein, and albumin levels compared to all other groups. No significant differences were seen when evaluating sex, clinical parameters, character of diarrhea or vomiting among all groups. Young dogs are more likely to suffer from viral enteritis. Based on clinical parameters it is not possible to differentiate a virus-positive from a virus-negative dog or to diagnose a certain virus species. Besides the young age, parvovirus infection is associated with typical changes in laboratory parameters, but not with specific clinical signs. A virologic fecal examination is always indicated.

To investigate the association between the clinical characteristics and clinical modes of surgically treated lung cancer patients, we conducted a retrospective study with 1097 lung cancer patients receiving pulmonary resection between 2012 and 2013.A physical examination or screening (PES) group (n = 267) and a symptomatic (SY) group (n = 830) were established depending on the new clinical mode (sequence of physical examination, early detection and sequential medical treatment) and the conventional mode (hospitalization due to occurrence of relevant symptoms), respectively.A higher proportion of patients referred to our unit directly form a junior medical unit is found in PES group (43.8%, 117/267 vs 13.6%, 113/830) (P < 0.001) and 37.5% (100/267) patients in PES group spent <1 months from detection or first medical visit to diagnosis compared with 15.4% (128/830) patient in SY group (P < 0.001). A significantly higher proportion of PES patients versus SY patients received video-assisted thoracoscopic surgery (VATS) resection (67.8%, 183/267 vs 42.6%, 352/830; P < 0.001). A significantly higher proportion of PES patients versus SY patients chose sublobar resection (16.9%, 45/267 vs 7.6%, 63/830; P < 0.001). A significantly higher proportion of PES patients versus SY patients are at stage 0 or I (64.4%, 172/267 vs 40.7%, 338/830; P < 0.000). The postoperative incidence rate of complications in 30 days is significantly higher in SY group than in PES group (34.9% vs 27.3%; P = 0.022).Helping to early diagnosis and surgical treatment, early tumor detection via PES may contribute to significantly higher proportions of early-stage lung cancer, use of VATS pulmonary resection, and sublobectomy as well as lower complication rate.

Tinea incognita is a dermatophyte infection with atypical clinical features modified by the improper use of corticosteroids or calcineurin inhibitors. The aim of this study was to analyze clinical and microbiological features of patients with tinea incognita. A total of 6326 patients referred to mycology laboratory between January 2008 and January 2011 for mycological examination with a diagnosis of tinea incognita were reviewed retrospectively. Twenty-one patients, 13 (61.9%) women and 8 (38.1%) men, mean age 42.2±36.8, were included in the study. Of them, lesions were localized in 15 (71.4%) patients and widespread in six (28.6%) patients. The mean duration of the disease was 9.5 (range 1-120) months. All patients had a history of treatment with steroids. Before admission, most of them had been misdiagnosed as eczema or psoriasis. Microscopic examination revealed hyphae and spores in most of the cases (n=17, 80.95%). Mycological cultures were positive in 19 (90.5%) patients. The most frequently isolated dermatophyte was Trichophyton rubrum (n=14, 66.7%). This case series revealed Trichophyton rubrum as the most frequent agent of tinea incognita. To the best of our knowledge, this is the largest case series from Turkey describing clinical features and mycological agents of tinea incognita.

The purpose is to determine which assessment measures identify medical students at risk of failing a clinical performance examination (CPX). Retrospective case-control, multiyear design, contingency table analysis, n = 149. We identified two predictors of CPX failure in patient-physician interaction skills: low clerkship ratings (odds ratio 1.79, P = .008) and student progress review for communication or professionalism concerns (odds ratio 2.64, P = .002). No assessments predicted CPX failure in clinical skills. Performance concerns in communication and professionalism identify students at risk of failing the patient-physician interaction portion of a CPX. This correlation suggests that both faculty and standardized patients can detect noncognitive traits predictive of failing performance. Early identification of these students may allow for development of a structured supplemental curriculum with increased opportunities for practice and feedback. The lack of predictors in the clinical skills portion suggests limited faculty observation or feedback.

To explore use of clinical breast examination (CBE) among women receiving mammography. A retrospective cohort analysis of 100 women aged 50 years or older with at least one bilateral mammogram. Chart review documented demographic information, severity of illness, and performance of CBE (from 1 year prior to 18 months after the mammogram). The mean age of the 100 women was 63 years. They were predominantly unmarried (60%), nonwhite (58%), and not currently employed (57%). Three quarters (76%) had mammography and CBE (comprehensive screening), while the remaining 24% had mammography only. Sociodemographic factors did not differ for women with and without comprehensive screening (P>.1). However, patients of female providers were more likely to receive comprehensive screening than patients of male providers. Specifically, 95% of women seen by female attending physicians or fellows had comprehensive screening vs 67% for male attending physicians or fellows and 61% for residents (P=.008). Mammography may be replacing CBE especially among patients of male providers. Interventions targeted to these providers could help improve the use of CBE and mammography.

Diabetic teleretinal screening programs have been utilized successfully across the world to detect diabetic retinopathy (DR) and are well validated. Less information, however, exists on the ability of teleretinal imaging to detect nondiabetic ocular pathology. This study performed a retrospective evaluation to assess the ability of a community-based diabetic teleretinal screening program to detect common ocular disease other than DR. A retrospective chart review of 1,774 patients who underwent diabetic teleretinal screening was performed. Eye clinic notes from the Veterans Health Administration's electronic medical record, Computerized Patient Record System, were searched for each of the patients screened through teleretinal imaging. When a face-to-face examination note was present, the physical findings were compared to those obtained through teleretinal imaging. Sensitivity, specificity, and positive and negative predictive values were calculated for suspicious nerve, cataract, and age-related macular degeneration. A total of 903 patients underwent a clinical examination. The positive predictive value was highest for cataract (100%), suspicious nerve (93%), and macular degeneration (90%). The negative predictive value and the percent agreement between teleretinal imaging and a clinical examination were over 90% for each disease category. A teleretinal imaging protocol may be used to screen for other common ocular diseases. It may be feasible to use diabetic teleretinal photographs to screen patients for other potential eye diseases. Additional elements of the eye workup may be added to enhance accuracy of disease detection. Further study is necessary to confirm this initial retrospective review.

This study aimed to evaluate the demographic, clinical features, laboratory data, pathology and other survey in pediatric patients with cryofibrinogenemia. A 12-year retrospective chart review identified eight pediatric patients at Mackay Memorial Hospital, Taipei, Taiwan. The female-to-male ratio was 3:1. The mean age at symptom onset and of diagnosis was 10.3 ± 4.6 years and 12.3 ± 4 years, respectively. One child (12.5%) had primary cryofibrinogenemia. The common symptoms were purpura, arthralgia, and muscle weakness (100%). On laboratory examination, cryofibrinogen was positive in all patients. All patients had increased anti-thrombin III while 87.5% and 62.5% had abnormal protein S and protein C, respectively. All eight also complained of neurologic symptoms. One had vertebral artery narrowing, two showed increased T2-weighted signal intensity on the thalamus or white matter, and one had acute hemorrhagic encephalomyelitis on brain magnetic resonance imaging. This study reports on the presentations of cryofibrinogenemia, which is rare in children. Most cases are associated with autoimmune disease and have severe and complex presentations. Central nervous system involvement is common.

This retrospective longitudinal study evaluated the clinical performance of bonded ceramic inlays/onlays, placed by the first author in his private practice, in a 5 to 18-year period. The patients evaluated had been treated in the office for at least 7 years and were still in the practice up to year 2013. 130 randomly selected patients agreed to participate in the study. 93 bonded ceramic inlays/onlays (BCRs), were placed on posterior teeth in 47 subjects. Gender, age, tooth preparation, number, type, extent, location, quality and survival of the restorations, ceramic materials, luting resins cements, parafunctional habits, secondary caries and maintenance therapy were the variables evaluated. Cohen 's Kappa coefficient, on the quality analysis of the restorations, ranged from 0.78 to 1. Fisher 's exact test, Chi Square test, Kruskal-Wallis test and Mann-Whitney non-parametric test were indicated to analyze significant differences. At the initial examination, 87 (93.5%) restorations were in function and six failed (6.5%). 81 (93%) were rated as clinical successes. The observed mean survival time of those that remained functional was 11 years. The standard deviation was 4 years, with a 95% CI for the overall observed mean survival time (10 years-11 years, 9 months). 87 of 93 BCRs had a functional success of 93.5%, with an observed mean survival of 11 years. The clinical performance of bonded ceramic onlays was very acceptable. Bonded ceramic onlays showed a predictable, esthetic, and functional treatment, with acceptable longevity.

We undertook a retrospective study of 5,189 telephone calls made between January 2004 and June 2011 through our adult epilepsy clinic hotline to a single epileptologist initially and two epileptologists from June 2010 onwards. The majority of calls were made by patients themselves (72%), followed by family members (16%) and health care providers (11%). Half of the calls originated from outside the city limits. Most were related to medication (25%), notification of seizures (23%), appointments or tests (12%), and side effects (9%). Half of the workload was generated by 10% of patients. The hotline service appears to respond to needs, with most calls requiring rapid intervention. It is desirable to develop novel approaches to address the needs of high-frequency callers.

This study assessed the effect of introduction of diabetic retinopathy screening using non-mydriatic digital fundus photography (nDFP) in an urban academic family practice clinic on patient compliance to recommended dilated eye examination (REE). Two hundred four patients with diabetes mellitis who were noncompliant to annual REE were screened for diabetic retinopathy using nDFP. The images were electronically transmitted to the retinal specialist to triage them for follow-up REE based on the photographic findings. Retrospective review of their medical records compared the compliance to REE before and after nDFP screening. Compliance to REE increased from 9% before screening to 66.5% after screening (P < .0001). Good quality fundus images were obtained in 93% of the eyes. Introduction of nDFP for diabetic retinopathy screening in the family practice clinic can result in a dramatic increase in compliance to REE among patients with diabetes mellitis previously poorly compliant to REE.

Purpose: Iterative reconstruction (IR) algorithms have been adopted by medical centers in the past several years. IR has a potential to substantially reduce patient dose while maintaining or improving image quality. This study characterizes dose reductions in clinical settings for CT examinations using IR. Methods: We retrospectively analyzed dose information from patients who underwent abdomen/pelvis CT examinations with and without contrast media in multiple locations of our Healthcare system. A total of 743 patients scanned with ASIR on 64 slice GE lightspeed VCTs at three sites, and 30 patients scanned with SAFIRE on a Siemens 128 slice Definition Flash inmore » one site was retrieved. For comparison, patient data (n=291) from a GE scanner and patient data (n=61) from two Siemens scanners where filtered back-projection (FBP) was used was collected retrospectively. 30% and 10% ASIR, and SAFIRE Level 2 was used. CTDIvol, Dose-length-product (DLP), weight and height from all patients was recorded. Body mass index (BMI) was calculated accordingly. To convert CTDIvol to SSDE, AP and lateral dimensions at the mid-liver level was measured for each patient. Results: Compared with FBP, 30% ASIR reduces dose by 44.1% (SSDE: 12.19mGy vs. 21.83mGy), while 10% ASIR reduced dose by 20.6% (SSDE 17.32mGy vs. 21.83). Use of SAFIRE reduced dose by 61.4% (SSDE: 8.77mGy vs. 22.7mGy). The geometric mean for patients scanned with ASIR was larger than for patients scanned with FBP (geometric mean is 297.48 mmm vs. 284.76 mm). The same trend was observed for the Siemens scanner where SAFIRE was used (geometric mean: 316 mm with SAFIRE vs. 239 mm with FBP). Patient size differences suggest that further dose reduction is possible. Conclusion: Our data confirmed that in clinical practice IR can significantly reduce dose to patients who undergo CT examinations, while meeting diagnostic requirements for image quality.« less

Hospital-acquired complications increase length of stay and contribute to poorer patient outcomes. Older adults are known to be at risk for four key hospital-acquired complications (pressure injuries, pneumonia, urinary tract infections and delirium). These complications have been identified as sensitive to nursing characteristics such as staffing levels and level of education. The cost of these complications compared to the cost of admission severity, dementia, other comorbidities or age has not been established. To investigate costs associated with nurse-sensitive hospital-acquired complications in an older patient population 157,178 overnight public hospital episodes for all patients over age 50 from one Australian state, 2006/07 were examined. A retrospective cohort study design with linear regression analysis provided modelling of length-of-stay costs. Explanatory variables included patient age, sex, comorbidities, admission severity, dementia status, surgical status and four complications. Extra costs were based on above-average length-of-stay for each patient's Diagnosis Related Group from hospital discharge data. For adults over 50 who have length of stay longer than average for their diagnostic condition, comorbid dementia predicts an extra cost of A$874, (US$1,247); any one of four key complications predicts A$812 (US$1,159); each increase in admission severity score predicts A$295 ($US421); each additional comorbidity predicts A$259 (US$370), and for each year of age above 50 predicts A$20 (US$29) (all estimates significant at p<0.0001). Hospital-acquired complications and dementia cost more than other kinds of inpatient complexity, but admission severity is a better predictor of excess cost. Because complications are potentially preventable and dementia care in hospitals can be improved, risk-reduction strategies for common complications, particularly for patients with dementia could be cost effective. Complications and dementia were found to cost more

Schwannomatosis is a recently recognized form of neurofibromatosis characterized by multiple noncutaneous schwannomas, a histologically benign nerve sheath tumor. As more cases are identified, the reported phenotype continues to expand and evolve. We describe the spectrum of clinical findings in a cohort of patients meeting established criteria for schwannomatosis. We retrospectively reviewed the clinical records of patients seen at our institution from 1995-2011 who fulfilled either research or clinical criteria for schwannomatosis. Clinical, radiographic, and pathologic data were extracted with attention to age at onset, location of tumors, ophthalmologic evaluation, family history, and other stigmata of neurofibromatosis 1 (NF1) or NF2. Eighty-seven patients met the criteria for the study. The most common presentation was pain unassociated with a mass (46%). Seventy-seven of 87 (89%) patients had peripheral schwannomas, 49 of 66 (74%) had spinal schwannomas, seven of 77 (9%) had nonvestibular intracranial schwannomas, and four of 77 (5%) had intracranial meningiomas. Three patients were initially diagnosed with a malignant peripheral nerve sheath tumor; however, following pathologic review, the diagnoses were revised in all three cases. Chronic pain was the most common symptom (68%) and usually persisted despite aggressive surgical and medical management. Other common diagnoses included headaches, depression, and anxiety. Peripheral and spinal schwannomas are common in schwannomatosis patients. Severe pain is difficult to treat in these patients and often associated with anxiety and depression. These findings support a proactive surveillance plan to identify tumors by magnetic resonance imaging scan in order to optimize surgical treatment and to treat associated pain, anxiety, and depression.

The aim of endoscopic valve therapy in patients with emphysema is complete lobar atelectasis of the most emphysematous lobe. However, even after the radiological advent of atelectasis, great variability in clinical outcomes can be observed. The baseline clinical measures (vital capacity (VC), forced expiratory flow in 1 s (FEV1 ), residual volume (RV) and 6-min walk test (6-MWT)) and computed tomography variables (low attenuation volume (LAV) of the target lobe, LAV% of the target and the ipsilateral untreated lobe and LAV of the target lobe to LAV of the target lung and to LAV of the total lung) of 77 patients with complete atelectasis following valve therapy were retrospectively examined to determine their impact on patient´s outcome (changes in VC, FEV1 , RV and 6-MWT from baseline to the time of atelectasis). Low attenuation volume of the target lobe to LAV of the target lung predicts a significant FEV1 improvement in patients with complete lobar atelectasis following valve therapy. A 10% difference in that computed tomography predictor was associated with a 82-mL improvement in FEV1 (P = 0.006). Lower 6-MWT scores, low VC and high RV at baseline were significantly associated with greater improvement in the respective parameter (all P < 0.001). Low attenuation volume of the target lobe to LAV of the target lung and baseline clinical measures seem to significantly predict clinical outcomes in patients with complete lobar atelectasis following valve treatment. © 2016 Asian Pacific Society of Respirology.

Computed tomography (CT) is considered to be the reference method to evaluate middle ear structures. To evaluate the presence and severity of CT changes in the middle ear and establish if any specific clinical presentations are associated with otitis media. Medical records of animals referred for CT with history and clinical signs consistent with middle ear disease. Retrospective evaluation of CT examinations of tympanic bullae performed over a six year period. Medical records were reviewed for signalment, clinical signs and cytological evaluation of the external ear canal. Dogs were divided into three clinical groups: chronic otitis externa (Group 1), peripheral vestibular disorder (Group 2) and other clinical presentations (Group 3). Group 1 - Of 214 ears, 87 (40.7%) had CT abnormalities: 38 of 87 (17.7%) had material-filled bullae, 42 of 87 (19.6%) had thickened bullae walls and seven of 87 (3.2%) had lysis of the bulla. Abnormalities were significantly more frequent in dogs with suppurative otitis than in erythemato-ceruminous otitis (57% and 23%, respectively; P = 0.003). Proliferative otitis, particularly in French bulldogs, was associated with severe otitis media. Group 2 - Of the 106 ears, 91 (85.8%) had normal tympanic bullae. Group 3 - Of the 26 ears from deaf dogs, 17 had filled bullae; all nine affected dogs were Cavalier King Charles spaniels. All dogs with Claude Bernard Horner syndrome or head tilt had normal tympanic bullae. CT is useful for canine chronic otitis externa, particularly in suppurative or proliferative otitis, even in the absence of associated neurological signs. © 2017 ESVD and ACVD.

This study assesses the incidence of missed pelvic injuries in the pre-hospital setting. All blunt trauma patients (ISS ≥ 9) with pre-hospital suspicion of and/or radiologically proven pelvic fracture documented in the TraumaRegister DGU ® (TR-DGU) of the German Trauma Society DGU (2002-2011) were identified and retrospectively analyzed. Patients with a missed pelvic injury in the pre-hospital period were compared with those who were correctly identified. Of the 11,062 patients included, 7201 patients (65.1 %) had a pelvic fracture diagnosed on hospital admission. In 44.1 % (n = 3178) of the patients with confirmed pelvic fracture, no pelvic injury was suspected pre-clinically (overall sensitivity of the pre-hospital pelvic examination: 55.9 %). For type B and C pelvic fractures, 40.5 % and 32.3 %, respectively, were not suspected in the pre-hospital environment. Patients with a not-suspected pelvic injury were significantly more likely to have been involved in a motor vehicle accident, to have a GCS ≤ 8, to be intubated at the scene and to have an ISS of ≥25 (all p < 0.05). Independent risk factors for missing a pelvic injury in the pre-hospital setting were an AIS head ≥3, a GCS ≤ 8 and age above 60 years. The presence of hypotension (SBP ≤ 90 mmHg) as well as a high overall injury severity (ISS ≥ 25) decreased the risk of missing a pelvic injury. A significant proportion of severe pelvic fractures type B and C were not suspected in the pre-hospital setting. Therefore, in severely injured blunt trauma patients, a mechanical pelvic stabilization in the pre-hospital environment, irrespective of the findings of the physical examination of the pelvis, should be considered.

To describe the clinical pattern of viral central nervous system (CNS) infections and compare meningitis and encephalitis. This is a retrospective study reporting the clinical characteristics and outcome of 138 cases of viral meningitis and meningoencephalitis in a real life experience at a referral centre in Turin, Northern Italy. Enteroviruses were predominant in younger patients who were mainly presenting with signs of meningitis, had shorter hospital admission and absence of complications, whereas herpesviruses had more often signs of encephalitis, were more frequent in elderly patients, had longer hospital admission and frequent complications and sequelae. Two main clinical entities with different epidemiology, clinical aspects and prognosis may be identified within the group of viral CNS inefctions.

Increasing studies suggest the importance of including prospective memory measures in clinical evaluation of dementia due to its sensitivity and functional relevance. The Prospective and Retrospective Memory Questionnaire (PRQM) is originally a self-rated memory inventory that offers a direct comparison between prospective and episodic memory. However, the informant's report has been recognized as a more valid source of cognitive complaints. We thus aimed to examine the validity of the informant-rated form of the PRMQ in assessing memory function of the patients and in detecting individuals with early dementia. The informants of 140 neurological outpatients with memory complaints completed the Taiwan version of the PRMQ. Tests of prospective memory, short-term memory, and general cognitive ability were also administered to non-demented participants and patients with early stages of Alzheimer's disease (AD). Results showed significant relationships between the PRMQ ratings and objective cognitive measures, and showed that higher ratings on the PRMQ were associated with increasing odds of greater dementia severity. Receiver operative characteristic (ROC) curves showed an adequate ability of the PRMQ to identify patients with dementia (93% sensitivity and 84% specificity). Hierarchical regression revealed that the PRMQ has additional explanatory power for dementia status after controlling for age, education and objective memory test results, and that the prospective memory subscale owns predictive value for dementia beyond the retrospective memory subscale. The present study demonstrated the external validity and diagnostic value of informants' evaluation of their respective patients' prospective and retrospective memory functioning, and highlighted the important role of prospective memory in early dementia detection. The proxy-version of the PRMQ is a useful tool that captures prospective and episodic memory problems in patients with early AD, in combination with

The aim of curriculum reform in medical education is to improve students' clinical and communication skills. However, there are contradicting results regarding the effectiveness of such reforms. A study of internal medicine students was carried out using a static group design. The experimental group consisted of 77 students participating in 7 sessions of communication training, 7 sessions of skills-laboratory training and 7 sessions of bedside-teaching, each lasting 1.5 hours. The control group of 66 students from the traditional curriculum participated in equally as many sessions but was offered only bedside teaching. Students' cognitive and practical skills performance was assessed using Multiple Choice Question (MCQ) testing and an objective structured clinical examination (OSCE), delivered by examiners blind to group membership. The experimental group performed significantly better on the OSCE than did the control group (P < 0.01), whereas the groups did not differ on the MCQ test (P < 0.15). This indicates that specific training in communication and basic clinical skills enabled students to perform better in an OSCE, whereas its effects on knowledge did not differ from those of the traditional curriculum. Curriculum reform promoting communication and basic clinical skills are effective and lead to an improved performance in history taking and physical examination skills.

To gain a deeper understanding of the clinical journey taken by orofacial pain patients from initial presentation in primary care to treatment by oral and maxillofacial surgery. Retrospective audit. Data were collected from 101 consecutive patients suffering from chronic orofacial pain, attending oral and maxillofacial surgery clinics between 2009 and 2010. Once the patients were identified, information was drawn from their hospital records and referral letters, and a predesigned proforma was completed by a single examiner (EVB). Basic descriptive statistics and non-parametric inferential statistical techniques (Krushal-Wallis) were used to analyse the data. DATA AND DISCUSSION: Six definitive orofacial pain conditions were represented in the data set, 75% of which were temporomandibular disorders (TMD). Individuals within our study were treated in nine different hospital settings and were referred to 15 distinct specialties. The mean number of consultations received by the patients in our study across all care settings is seven (SD 5). The mean number of specialities that the subjects were assessed by was three (SD 1). The sample set had a total of 341 treatment attempts to manage their chronic orofacial pain conditions, of which only 83 (24%) of all the treatments attempted yielded a successful outcome. Improved education and remuneration for primary care practitioners as well as clear care pathways for patients with chronic orofacial pain should be established to reduce multiple re-referrals and improve efficiency of care. The creation of specialist regional centres for chronic orofacial pain may be considered to manage severe cases and drive evidence-based practice.

The changes in metabolic pathways and metabolites due to critical illness result in a highly complex and dynamic metabolic state, making safe, effective management of hyperglycemia and hypoglycemia difficult. In addition, clinical practices can vary significantly, thus making GC protocols difficult to generalize across units.The aim of this study was to provide a retrospective analysis of the safety, performance and workload of the stochastic targeted (STAR) glycemic control (GC) protocol to demonstrate that patient-specific, safe, effective GC is possible with the STAR protocol and that it is also generalizable across/over different units and clinical practices. Retrospective analysis of STAR GC in the Christchurch Hospital Intensive Care Unit (ICU), New Zealand (267 patients), and the Gyula Hospital, Hungary (47 patients), is analyzed (2011-2015). STAR Christchurch (BG target 4.4-8.0 mmol/L) is also compared to the Specialized Relative Insulin and Nutrition Tables (SPRINT) protocol (BG target 4.4-6.1 mmol/L) implemented in the Christchurch Hospital ICU, New Zealand (292 patients, 2005-2007). Cohort mortality, effectiveness and safety of glycemic control and nutrition delivered are compared using nonparametric statistics. Both STAR implementations and SPRINT resulted in over 86 % of time per episode in the blood glucose (BG) band of 4.4-8.0 mmol/L. Patients treated using STAR in Christchurch ICU spent 36.7 % less time on protocol and were fed significantly more than those treated with SPRINT (73 vs. 86 % of caloric target). The results from STAR in both Christchurch and Gyula were very similar, with the BG distributions being almost identical. STAR provided safe GC with very few patients experiencing severe hypoglycemia (BG < 2.2 mmol/L, <5 patients, 1.5 %). STAR outperformed its predecessor, SPRINT, by providing higher nutrition and equally safe, effective control for all the days of patient stay, while lowering the number of measurements and

Purpose To assess the impact of clinical history on the maximum Prostate Imaging Recording and Data System (PI-RADS) version 2 (v2) score assigned to multiparametric magnetic resonance (MR) imaging of the prostate. Materials and Methods This retrospective cohort study included 120 consecutively selected multiparametric prostate MR imaging studies performed between November 1, 2016, and December 31, 2016. Sham clinical data in four domains (digital rectal examination, prostate-specific antigen level, plan for biopsy, prior prostate cancer history) were randomly assigned to each case by using a balanced orthogonal design. Six fellowship-trained abdominal radiologists independently reviewed the sham data, actual patient age, and each examination while they were blinded to interreader scoring, true clinical data, and histologic findings. Readers were told the constant sham histories were true, believed the study to be primarily investigating interrater agreement, and were asked to assign a maximum PI-RADS v2 score to each case. Linear regression was performed to assess the association between clinical variables and maximum PI-RADS v2 score designation. Intraclass correlation coefficients (ICCs) were obtained to compare interreader scoring. Results Clinical information had no significant effect on maximum PI-RADS v2 scoring for any of the six readers (P = .09-.99, 42 reader-variable pairs). Distributions of maximum PI-RADS v2 scores in the research context were similar to the distribution of the scores assigned clinically and had fair-to-excellent pairwise interrater agreement (ICC range: 0.53-0.76). Overall interrater agreement was good (ICC: 0.64; 95% confidence interval: 0.57, 0.71). Conclusion Clinical history does not appear to be a substantial bias in maximum PI-RADS v2 score assignment. This is potentially important for clinical nomograms that plan to incorporate PI-RADS v2 score and clinical data into their algorithms (ie, PI-RADS v2 scoring is not confounded by

Clinical diagnosis of syphilis: a ten-year retrospective analysis in a South Australian urban sexual health clinic.

National notifications for infectious syphilis in Australia have increased in recent years. Outside of sexual health clinics, junior clinicians seldom encounter this disease in its infectious stage (primary, secondary and early latent). With such a variable clinical presentation, textbook teaching is no substitute for real-life experience. The importance of accurate classification and staging of disease is relevant to the risk of transmission and determines treatment duration. In this article, the authors review the clinical presentation of syphilis over ten years in an urban sexual health clinic with a focus on the clinical presentation and diagnosis of infectious syphilis, in particular secondary syphilis, compared with that outlined in the Australian National Notifiable Diseases Surveillance System guidelines. This retrospective review of all patients diagnosed with syphilis at an urban sexual health clinic showed that between 2005 and 2015, 226 cases of syphilis were diagnosed. Documentation of impression of clinical staging of disease was present in 46% of the cases. Seventeen of these cases were recorded as secondary syphilis. The criteria used by clinicians to diagnose the secondary syphilis cases were consistent with criteria defined by the Australian National Notifiable Diseases Surveillance System. All cases of secondary syphilis had at least one cutaneous manifestation of disease. The demographic of the cohort of syphilis cases was consistent with that recorded in the literature. This review showed that the clinician's diagnosis of secondary syphilis in this service is consistent with the National Notifiable Diseases Surveillance System guidelines. Continuing education of junior medical staff is important to facilitate diagnosis and improve documentation of clinical staging, minimise disease transmission and ensure appropriate treatment. © The Author(s) 2016.

Background & objectives: Differential diagnosis of Crimean-Congo haemorrhagic fever (CCHF) from other acute febrile illnesses with haemorrhagic manifestation is challenging in India. Nosocomial infection is a significant mode of transmission due to exposure of healthcare workers to blood and body fluids of infected patients. Being a risk group 4 virus, laboratory confirmation of infection is not widely available. In such a situation, early identification of potential CCHF patients would be useful in limiting the spread of the disease. The objective of this study was to retrospectively analyse clinical and laboratory findings of CCHF patients that might be useful in early detection of a CCHF case in limited resource settings. Methods: Retrospective analysis of clinical and laboratory data of patients suspected to have CCHF referred for diagnosis from Gujarat and Rajasthan States of India (2014-2015) was done. Samples were tested using CCHF-specific real time reverse transcription (RT)-PCR and IgM ELISA. Results: Among the 69 patients referred, 21 were laboratory confirmed CCHF cases of whom nine had a history of occupational exposure. No clustering of cases was noted. Platelet count cut-off for detection of positive cases by receiver operating characteristic curve was 21.5×10[9]/l with sensitivity 82.4 per cent and specificity 82.1 per cent. Melaena was a significant clinical presentation in confirmed positive CCHF patients. Interpretation & conclusions: The study findings suggest that in endemic areas thrombocytopenia and melaena may be early indicators of CCHF. Further studies are needed to confirm these findings.

The replacement of lost teeth with dental implants is a widespread treatment whose associated problems are also frequently encountered. Nevertheless, the factors associated with early implant failure have not been well documented. Further analyses of the factors influencing osseointegration establishment are required to maximize the predictability of the procedure and minimize implant failures. The purpose of this retrospective clinical study was to explore the association between possible risk factors and early implant failure. This retrospective clinical study evaluated 142 participants who received 276 external connection BTI implants between 2007 and 2011. Participant variables (age, sex, systemic disease, tobacco use, alcohol consumption, bruxism, and degree of periodontal disease), implant variables (type of edentulism, localization, area, diameter, length, and bone quality), intervention variables (expansion mechanisms, sinus augmentation techniques, bone regeneration, and implant insertion), and postoperative variables (presence of pain/inflammation at 1 week postsurgery) were studied. A multilevel logistic regression model (mixed effects-type model) was used to determine the influence of variables on early implant failure. Early implant failure was significantly associated with the male sex (P=.001), severe periodontal disease (P=.005), short implants (P=.001), expansion technique (P=.002), and postoperative pain/inflammation at 1 week postsurgery (P<.001). Early dental implant failure is more frequent in men and in individuals with severe periodontal disease, short implants, pain/inflammation at 1 week postsurgery, or bone expansion treatment.

In a retrospective chart review, we examined the effects of ketamine, an N-methyl-d-aspartate (NMDA) receptor antagonist, as electroconvulsive therapy (ECT) anaesthetic in patients suffering from therapy-resistant depression. We included 42 patients who received ECT treatment with either ketamine (n = 16) or the barbiturate thiopental (n = 26). We analysed the number of sessions until completion of ECT treatment (used as a surrogate parameter for outcome), psychopathology as assessed by pre- and post-ECT Mini-Mental State Examination (MMSE) and Hamilton Rating Scale for Depression (HAM-D) scores as well as ECT and seizure parameters (stimulation dose, seizure duration and concordance, urapidil dosage for post-seizure blood pressure management). The ketamine group needed significantly fewer ECT sessions and had significantly lower HAM-D and higher MMSE scores afterwards. As expected, the ketamine group needed more urapidil for blood pressure control. Taking into account the limits inherent in a retrospective study design and the rather small sample size, our results nonetheless point towards synergistic effects of ECT and ketamine anaesthesia, less cognitive side effects and good tolerability of ketamine.

Clinical Features of Schwannomatosis: A Retrospective Analysis of 87 Patients

2012-01-01

Background. Schwannomatosis is a recently recognized form of neurofibromatosis characterized by multiple noncutaneous schwannomas, a histologically benign nerve sheath tumor. As more cases are identified, the reported phenotype continues to expand and evolve. We describe the spectrum of clinical findings in a cohort of patients meeting established criteria for schwannomatosis. Methods. We retrospectively reviewed the clinical records of patients seen at our institution from 1995–2011 who fulfilled either research or clinical criteria for schwannomatosis. Clinical, radiographic, and pathologic data were extracted with attention to age at onset, location of tumors, ophthalmologic evaluation, family history, and other stigmata of neurofibromatosis 1 (NF1) or NF2. Results. Eighty-seven patients met the criteria for the study. The most common presentation was pain unassociated with a mass (46%). Seventy-seven of 87 (89%) patients had peripheral schwannomas, 49 of 66 (74%) had spinal schwannomas, seven of 77 (9%) had nonvestibular intracranial schwannomas, and four of 77 (5%) had intracranial meningiomas. Three patients were initially diagnosed with a malignant peripheral nerve sheath tumor; however, following pathologic review, the diagnoses were revised in all three cases. Chronic pain was the most common symptom (68%) and usually persisted despite aggressive surgical and medical management. Other common diagnoses included headaches, depression, and anxiety. Conclusions. Peripheral and spinal schwannomas are common in schwannomatosis patients. Severe pain is difficult to treat in these patients and often associated with anxiety and depression. These findings support a proactive surveillance plan to identify tumors by magnetic resonance imaging scan in order to optimize surgical treatment and to treat associated pain, anxiety, and depression.

Helping patients maximize their potential using expert coaching to facilitate lifestyle change is an important practice area for clinical nurse specialists (CNSs). The purpose is to determine the usefulness of objective structured clinical examinations (OSCEs) for evaluating CNS students' coaching competencies in the context of facilitating lifestyle change. Despite the use of OSCEs to assess competencies in clinical skills (eg, performance of procedures, decision making), its potential for evaluating coaching competencies for lifestyle change has not been demonstrated. We developed 4 OSCEs dealing with coaching patients in exercise, weight loss, stress reduction, or nonpharmacologic management of hyperlipidemia. Evaluation criteria included (1) approach to the patient, (2) information gathering, (3) motivational interviewing, and (4) management (medical and behavioral strategies). Student performance ranged from highly organized with proficient coaching skills to disorganized and focused solely on clinical management and prescriptive communication. Student responses were positive. Objective structured clinical examinations were highly useful for evaluating CNS students' coaching competencies for lifestyle change. Using OSCEs early in the semester to provide students feedback on their performance and again at the end to determine improvement optimizes use of this teaching strategy.

1995-01-01

All cases examined postmortem at the Mayo Clinic that met the classic neuropathological criteria for progressive supranuclear palsy (PSP) were identified for retrospective clinical analyses. The necropsy material was re-examined by a second neuropathologist to confirm the pathological diagnosis of PSP, yielding 12 cases. A range of clinical signs were documented in these patients, with numerous findings beyond those noted in the original descriptions of this disorder. Atypical clinical findings included absence of supranuclear gaze palsy (two cases), prominent asymmetry (two), arm dystonia (two), upper limb apraxia (two), myoclonus (two), chorea (one), eyelid opening apraxia (one), and respiratory disturbance (one). A definite clinical diagnosis of PSP had been made during life in only eight of the 12 patients. From the retrospective analysis of these 12 cases, a set of clinical criteria were developed for the premortem diagnosis of PSP emphasising differences from other akinetic-rigid disorders.

Negative pressure wound therapy (NPWT) is an established modality in the treatment of challenging wounds. However, most existing clinical evidence is derived from the use of open-cell polyurethane foam at -125 mmHg. Alternative negative pressure systems are becoming available, which use gauze at a pressure of -80 mmHg. This study describes clinical results from a retrospective non comparative analysis of 30 patients treated with Chariker-Jeter gauze-based negative pressure systems (V1STA, Versatile-1 and EZ-Care; Smith & Nephew, Inc.) in a long-term care setting. The mean age of the patients was 72 years. The wounds consisted of chronic (n = 11), surgical dehiscence (n = 11) and surgical incision (n = 8). Wound volume and area were recorded at commencement and at the cessation of therapy. Discontinuation of therapy was instigated upon closure through secondary intention or when size and exudate were sufficiently reduced that the wounds could be managed by conventional wound dressing (median 41 days). An overall median reduction in wound volume of 88.0% (P < 0.001) and a 68.0% reduction in area (P < 0.001) compared with baseline were observed over the course of NPWT. The overall rate of volume reduction (15.1% per week) compares favourably with published data from foam-based systems.

Genital or vulval lichen planus (VLP) may have a disabling effect on a patient's quality of life. Evidence-based management guidelines are lacking for VLP. We sought to review clinical presentation and treatment of patients who received a diagnosis of VLP. The 100 consecutive patients who received a diagnosis of VLP at Mayo Clinic between January 1, 1997, and December 31, 2015, were reviewed retrospectively. Descriptive statistics were used for data analysis. Fisher's exact test and the Wilcoxon rank sum test were used for analysis of categorical and continuous variables, respectively. All statistical tests were 2 sided, with the α level set at .05 for statistical significance. The time to diagnosis for 49% of patients was more than 1 year. Three patients (3%) had vulval dysplasia, including invasive squamous cell carcinoma. Sixty-eight patients (68%) had multisite lichen planus disease. Eleven patients (11%) had disease remission. Dermatology was the lead specialty for 9 of these cases of remission. This was a retrospective, small-cohort study. A low frequency of disease remission was seen in patients with VLP. Patients with lichen planus benefit considerably from dermatology consultation. Further research is warranted to establish high-quality, evidence-based guidelines for multidisciplinary management of this challenging disease. Copyright © 2017 American Academy of Dermatology, Inc.

Mild hypercholesterolemia, normal plasma triglycerides, and normal glucose levels across dementia staging in Alzheimer's disease: a clinical setting-based retrospective study.

2011-08-01

We examined retrospectively the concurrent relationships between fasting plasma total cholesterol, triglycerides, and glucose levels, and Alzheimer's disease (AD), in a clinical setting-based study. Total cholesterol level was higher in patients with AD compared to elderly controls; triglycerides or glucose levels did not significantly differ between the 2 groups. Respective plotted trajectories of change in cholesterol level across age were fairly parallel. No significant difference in total cholesterol levels was recorded between patients with AD classified by the Clinical Dementia Rating (CDR) score subgroups. These results suggest that patients with AD have relative mild total hypercholesterolemia, normal triglyceridemia, and normal fasting plasma glucose level. Mild total hypercholesterolemia seems to be permanent across age, and across dementia severity staging, and fairly parallels the trajectory of age-related change in total cholesterolemia of healthy controls. We speculate that these biochemical parameters pattern may be present long before-a decade at least-the symptomatic onset of the disease.

Clinical signs in the Wernicke-Korsakoff complex: a retrospective analysis of 131 cases diagnosed at necropsy.

Harper, C G; Giles, M; Finlay-Jones, R

1986-01-01

A recent necropsy study has shown that 80% of patients with the Wernicke-Korsakoff syndrome were not diagnosed as such during life. Review of the clinical signs of these cases revealed that only 16% had the classical clinical triad and 19% had no documented clinical signs. The incidence of clinical signs in this and other retrospective pathological studies is very different from that of prospective clinical studies. This discrepancy may relate to "missed" clinical signs but the magnitude of the difference suggests that at least some cases of the Wernicke-Korsakoff syndrome may be the end result of repeated subclinical episodes of vitamin B1 deficiency. In order to make the diagnosis, clinicians must maintain a high index of suspicion in the "at risk" group of patients, particularly alcoholics. Investigations of thiamine status may be helpful and if the diagnosis is suspected, parenteral thiamine should be given. PMID:3701343

Some authorities have questioned the utility of performing clinical pelvimetry as part of routine prenatal care. This study determined the frequency with which clinical pelvimetry is still performed at two military hospitals and whether the results of pelvimetry influence the management of labor and delivery. We conducted a retrospective review of prenatal records at two military hospitals. One was an overseas hospital, and one was a family medicine teaching hospital in the United States. The records of 660 pregnant women were reviewed to identify documentation that pelvimetry was performed during prenatal care and whether there was evidence that the physician managing labor and delivery altered management based on pelvimetry results. Seventy percent (461) of the 660 records reviewed had all pelvimetry measurements documented as normal, or the provider had written "good for TOL (trial of labor)," "proven to XX pounds," or similar annotation that pelvimetry was normal. Nine percent (58 records) had no documentation of pelvimetry (pelvimetry section left blank). The remaining 21% (141 charts) had at least one pelvimetry measurement listed as abnormal on the initial prenatal exam. No admission note, progress note, or operative note recorded during labor and delivery made reference to clinical pelvimetry results. No abnormal pelvimetry result was referenced in follow-up visits or appeared to make any difference in mode of delivery or treatment in labor. Two women (one at each institution) had initial visit notes indicating the need to consider radiographic pelvimetry based on the results of clinical exam, but this test was not done in either case, and both women delivered vaginally. Our study indicates that clinical pelvimetry does not change management of pregnant patients. Current practice is to allow all women a trial of labor regardless of pelvimetry results. This makes the routine performance and recording of clinical pelvimetry a waste of time, a potential

Background Hospital-acquired complications increase length of stay and contribute to poorer patient outcomes. Older adults are known to be at risk for four key hospital-acquired complications (pressure injuries, pneumonia, urinary tract infections and delirium). These complications have been identified as sensitive to nursing characteristics such as staffing levels and level of education. The cost of these complications compared to the cost of admission severity, dementia, other comorbidities or age has not been established. Method To investigate costs associated with nurse-sensitive hospital-acquired complications in an older patient population 157,178 overnight public hospital episodes for all patients over age 50 from one Australian state, 2006/07 were examined. A retrospective cohort study design with linear regression analysis provided modelling of length-of-stay costs. Explanatory variables included patient age, sex, comorbidities, admission severity, dementia status, surgical status and four complications. Extra costs were based on above-average length-of-stay for each patient’s Diagnosis Related Group from hospital discharge data. Results For adults over 50 who have length of stay longer than average for their diagnostic condition, comorbid dementia predicts an extra cost of A$874, (US$1,247); any one of four key complications predicts A$812 (US$1,159); each increase in admission severity score predicts A$295 ($US421); each additional comorbidity predicts A$259 (US$370), and for each year of age above 50 predicts A$20 (US$29) (all estimates significant at p<0.0001). Discussion Hospital-acquired complications and dementia cost more than other kinds of inpatient complexity, but admission severity is a better predictor of excess cost. Because complications are potentially preventable and dementia care in hospitals can be improved, risk-reduction strategies for common complications, particularly for patients with dementia could be cost effective.

Undetermined thyroid cytology precludes any definitive distinction between malignant and benign lesions. Recently several classifications have been proposed to split this category into two or more cytological subcategories related to different malignancy risk rates. The current study was performed retrospectively to investigate the results obtained separating "undetermined" cytologic reports into two categories: "follicular lesion" (FL) and "atypia of undetermined significance" (AUS). Biochemical, clinical, and echographic features of each category were also retrospectively analyzed. Altogether, 316 undetermined fine-needle aspirated cytologies (FNACs) were reclassified as 74 FL and 242 AUS. Histological control leads to a diagnosis of carcinomas, adenomas, and nonneoplastic lesions, respectively, in 42.2%, 20%, and 37.8% of AUS and in 8.3%, 69.4%, and 22.2% of FL. Among biochemical, clinical, cytological, and echographic outcomes, altered thyroid autoantibodies, multiple versus single nodule, AUS versus FL, and presence of intranodular vascular flow were statistically significant to differentiate adenoma from carcinoma and from nonneoplastic lesions, whereas no significant differences were found between carcinomas and nonneoplastic lesions for these parameters. The results of this retrospective study show that undetermined FNAC category can further be subclassified in AUS and FL, the former showing higher malignancy rate. Further prospective studies are needed to confirm our results.

Mammographic screening with clinical breast examination has been recommended in Japan since 2000. Although mammographic screening without clinical breast examination has not been recommended, its introduction is anticipated. The efficacies of mammographic screening with and without clinical breast examination were evaluated based on the results of randomized controlled trials. PubMed and other databases for studies published between 1985 and 2014 were searched. The study design was limited to randomized controlled trials to evaluate mortality reduction from breast cancer. Five studies were eligible for meta-analysis of mammographic screening without clinical breast examination. The relative risk for women aged 40–74 years was 0.75 (95% confidence interval, 0.67–0.83). Three studies evaluated the efficacy of mammographic screening with clinical breast examination. The relative risk for women aged 40–64 years was 0.87 (95% confidence interval, 0.77–0.98). The number needed to invite was always lower in mammographic screening without clinical breast examination than in mammographic screening with clinical breast examination. In both screening methods, the number needed to invite was higher in women aged 40–49 years than in women aged 50–70 years. These results suggest that mammographic screening without clinical breast examination can afford higher benefits to women aged 50 years and over. Although evidence of the efficacy of mammographic screening without clinical breast examination was confirmed based on the results of the randomized controlled trials, a Japanese study is needed to resolve local problems.

The purpose of this study is to quantify the clinical impact of resident-attending discrepancies at a tertiary referral academic radiology residency program by assessing rates of intervention, discrepancy confirmation, recall rate, and management change rate; furthermore, a discrepancy categorization system will be assessed. Retrospective review of the records was performed for n = 1482 discrepancies that occurred in the 17-month study period to assess the clinical impact of discrepancies. Discrepancies were grouped according to a previously published classification system. Management changes were recorded and grouped by severity. The recall rate was estimated for discharged patients. Any confirmatory testing was reviewed to evaluate the accuracy of the discrepant report. Categorical variables were compared to the chi-square test. The 1482 discrepancies led to management change in 661 cases (44.6%). The most common management change was follow-up imaging. Procedural interventions including surgery occurred in 50 cases (3.3%). The recall rate was 2.6%. Management changes were more severe with computed tomography examinations, inpatients, and when the discrepancy was in the chest and abdomen subspecialty. Also, management changes correlated with the discrepancy category assigned by the attending at the time of review. Resident-attending discrepancies do cause management changes in 44.6% of discrepancies (0.62% overall); the most frequent change is follow-up imaging. The discrepancy categorization assigned by the attending correlated with the severity of management change. Copyright © 2018 The Association of University Radiologists. Published by Elsevier Inc.

The Accreditation Council for Graduate Medical Education (ACGME) guidelines requires residency programs to teach and evaluate residents in six overarching "core competencies" and document progress through educational milestones. To assess the progress of orthopedic interns' skills in performing a history, physical examination, and documentation of the encounter for a standardized patient with spinal stenosis, an objective structured clinical examination (OSCE) was conducted for 13 orthopedic intern residents, following a 1-month boot camp that included communications skills and curriculum in history and physical examination. Interns were objectively scored based on their performance of the physical examination, communication skills, completeness and accuracy of their electronic medical record (EMR), and their diagnostic conclusions gleaned from the patient encounter. The purpose of this study was to meaningfully assess the clinical skills of orthopedic post-graduate year (PGY)-1 interns. The findings can be used to develop a standardized curriculum for documenting patient encounters and highlight common areas of weakness among orthopedic interns with regard to the spine history and physical examination and conducting complete and accurate clinical documentation. A major orthopedic specialty hospital and academic medical center. Thirteen PGY-1 orthopedic residents participated in the OSCE with the same standardized patient presenting with symptoms and radiographs consistent with spinal stenosis. Videos of the encounters were independently viewed and objectively evaluated by one investigator in the study. This evaluation focused on the completeness of the history and the performance and completion of the physical examination. The standardized patient evaluated the communication skills of each intern with a separate objective evaluation. Interns completed these same scoring guides to evaluate their own performance in history, physical examination, and communications

Acute lower respiratory tract illness is common among children seen in primary care. We reviewed the accuracy and precision of the clinical examination in detecting pneumonia in children. Although most cases are viral, it is important to identify bacterial pneumonia to provide appropriate therapy. Studies were identified by searching MEDLINE from 1982 to 1995, reviewing reference lists, reviewing a published compendium of studies of the clinical examination, and consulting experts. Observer agreement is good for most signs on the clinical examination. Each study was reviewed by 2 observers and graded for methodologic quality. There is better agreement about signs that can be observed (eg, use of accessory muscles, color, attentiveness; kappa, 0.48-0.66) than signs that require auscultation of the chest (eg, adventitious sounds; kappa, 0.3). Measurements of the respiratory rate are enhanced by counting for 60 seconds. The best individual finding for ruling out pneumonia is the absence of tachypnea. Chest indrawing, and other signs of increased work of breathing, increases the likelihood of pneumonia. If all clinical signs (respiratory rate, auscultation, and work of breathing) are negative, the chest x-ray findings are unlikely to be positive. Studies are needed to assess the value of clinical findings when they are used together.

increasingly, reflection is highlighted as integral to core practice competencies but empirical research into the relationship between reflection and performance in the clinical workplace is scarce. this study investigated the relationship between reflection ability and clinical performance. we designed a cross-sectional and a retrospective-longitudinal cohort study. Data from first, second and third year midwifery students were collected to study the variables 'clinical performance' and 'reflection ability'. Data were analysed with SPSS for Windows, Release 20.0. Descriptive statistics, Pearson׳s Product Moment Correlation Coefficients (r) and r² values were computed to investigate associations between the research variables. the results showed a moderate observed correlation between reflection ability and clinical performance scores. When adopting a cross-sectional perspective, all correlation values were significant (p<0.01) and above 0.4, with the exception of the third year correlations. Assuming perfect reliability in the measurement, the adjusted correlations, for year 2 and year 3 indicated a high association between reflection ability and clinical performance (>0.6). The results based on the retrospective-longitudinal data set explained a moderate proportion of the variance after correction for attenuation. Finally, the results indicate that 'reflection ability' scores of earlier years are significant related with 'clinical performance' scores of subsequent years. These results suggest that (1) reflection ability is linked to clinical performance; (2) that written reflections are an important, but not the sole way to assess professional competence and that (3) reflection is a contributor to clinical performance improvement. the data showed a moderate but significant relationship between 'reflection ability' and 'clinical performance' scores in clinical practice of midwifery students. Reflection therefore seems an important component of professional

To evaluate long-term clinical performance of 1-stage dental implant prostheses at a single clinic, emphasizing clinical and demographic characteristics that affect implant survival. Dental records of all 308 patients (674 implants) treated with 1-stage implants at Mayo Clinic from October 1993 through May 2000 were reviewed from implant placement to last visit. Exposure and outcome variables affecting performance were collected separately to control bias in the data collection process. Additional confounding factors (age and sex) were adjusted with the stratified Cox proportional hazards model. Implant survival was determined by means of a Kaplan-Meier survival estimate. The log-rank test was used to determine the role of clinical and demographic variables in implant survival. The relative risk associated with the possible effect of clinical and demographic variables on implant survival was estimated with the Cox proportional hazards model. The implant survival rate (n = 654 implants) was 97% (mean +/- SD follow-up, 21.0 +/- 18.8 months; range, 1 to 78 months). Performance bias was limited because nearly all patients were treated by 1 prosthodontist. Two implants failed after loading (6 and 9 months). The incidence of complications was less than 4%. Among the implant failures, use of heterogeneous bone graft was associated with 4.8 times more failures than was use of autogenous bone graft (P = .04). After augmentation, delaying implant placement for 5 to 6 months resulted in 8.6 times more failures than the rate after earlier placement (P < .001). Retrospective review of the clinical performance of a 1-stage dental implant system yielded a 97% survival rate, with no failures noted after 13 months. Prosthetic complications were low, especially for fixed implant prostheses. Clinical performance of 1-stage dental implant prostheses between 1993 and 2000 demonstrated a high level of predictability.

Primary osteoarthritis (OA) is the most common cause of pain arising from the acromioclavicular (AC) joint. The true incidence is unknown because of differences in the criteria used to define arthritis in various studies. The proper diagnosis of AC joint OA requires a thorough physical examination, radiographic findings, and a diagnostic local anesthetic injection. The goal of this study was to assess the effects and safety of ultrasound (US) versus palpation-guided acromioclavicular (AC) joint intra-articular (IA) corticosteroid injection for patients with osteoarthritis (OA) of the AC joint. Retrospective, compared clinical study. University hospital outpatient pain clinic. We retrospectively reviewed the charts of patients with AC joint degenerative OA who had undergone US or palpation-guided AC joint IA corticosteroid injection between January 2012 and December 2013 at our outpatient clinic. One hundred consecutive patients identified from chart review met inclusion criteria. Patients (N = 50) in US guide AC joint IA steroid injection group were administered a mixture of 0.5% lidocaine (1 mL) with triamcinolone (20 mg/mL; 0.5 mL) and radiographic contrast material (0.5 mL) and patients (N = 50) in palpation-guided AC joint IA steroid injection group were administered a mixture of 0.5% lidocaine (1 mL) with triamcinolone (20 mg/mL; 0.5 mL) and 0.5 mL of radiographic contrast material. Results were measured using the Shoulder Pain and Disability Index (SPADI), Verbal Numeric pain Scale (VNS) at rest (VNSar), under local pressure (VNSlp) ,and the arm adduction test (VNSaat) at the joint space area before injections and at one, 3, and 6 months after the injections. Successful treatment occurred when patients obtained significant pain relief (as measured by > 50% improvement in the VNS score and 20 point improvement in the SPADI) at one, 3, and 6 months after the injections. Univariable analysis was performed to evaluate the relationship between possible outcome

Objective: The aim of our study was to retrospectively validate a previously described rapid clinical score (RCS) in distinguishing tuberculous meningitis (TBM) from viral meningitis (VM) in people who are at increased risk of tuberculosis, as well as from cryptococcal meningitis (CM) in HIV-infected patients. Methods: We performed a retrospective study of patients admitted with a diagnosis of aseptic meningitis between January 2012 and December 2015, to a referral hospital for infectious diseases. The variables included in RCS were duration of symptoms before admission, neurological stage, cerebrospinal fluid (CSF) to blood glucose ratio, and CSF protein. We included in this retrospective study 31 patients with definite or probable TBM including 14 HIV-infected patients, 62 HIV-noninfected patients with VM, and 18 HIV-infected patients with CM. Results: The sensitivity of RCS to distinguish TBM from VM was 96.7%, with a specificity of 81.1% and the area under the receiver operating characteristic (ROC) curve was 0.949 (0.90–0.99). When all four criteria from the RCS were present, the specificity increased at 100%. In HIV-infected patients, the sensitivity and specificity of RCS in differentiating TBM from CM were 86.6% and 27.7%, respectively, and the area under the ROC curve was 0.669 (0.48–0.85). Conclusion: This easy-to-use RCS was found to be helpful in differentiating TBM from VM, with a better sensitivity than molecular amplification techniques and a relatively good specificity. However, the RCS was not useful to differentiate between TBM and CM in HIV-infected patients. PMID:29184338

The objectives of this study are (1) to collect retrospective clinical outcomes for acute decompensated heart failure cardiogenic shock and acute myocardial infarction cardiogenic shock, and compare current versus historical survival rates and clinical outcomes; (2) to evaluate Inova Heart and Vascular Institute site specific outcomes before and after initiation of the Cardiogenic Shock team on January 1, 2017; (3) to compare outcomes related to early implementation of mechanical circulatory support and hemodynamic-guided management versus historical controls; (4) to assess survival to discharge rate in patients receiving intervention from the designated shock team and (5) create a clinical archive of Cardiogenic Shock patient characteristics for future analysis and the support of translational research studies. This is an observational, retrospective, single center study. Retrospective and prospective data will be collected in patients treated at the Inova Heart and Vascular Institute with documented cardiogenic shock as a result of acute decompensated heart failure or acute myocardial infarction. This registry will include data from patients prior to and after the initiation of the multidisciplinary Cardiogenic Shock team on January 1, 2017. Clinical outcomes associated with early multidisciplinary team intervention will be analyzed. In the study group, all patients evaluated for documented cardiogenic shock (acute decompensated heart failure cardiogenic shock, acute myocardial infarction cardiogenic shock) treated at the Inova Heart and Vascular Institute by the Cardiogenic Shock team will be included.

Congestion in heart failure patients with reduced ejection fraction (HFrEF) is relevant and closely linked to the clinical course. Bedside blood pressure measurement during the Valsalva maneuver (Val) added to clinical examination may improve the assessment of congestion when compared to NT-proBNP levels and left atrial pressure (LAP) estimation by Doppler echocardiography, as surrogate markers of congestion in HFrEF. A clinical examination, LAP and blood tests were performed in 69 HFrEF ambulatory patients with left ventricular ejection fraction ≤ 40% and sinus rhythm. Framingham Heart Failure Score (HFS) was used to evaluate clinical congestion; Val was classified as normal or abnormal, NT-proBNP was classified as low (< 1000 pg/ml) or high (≥ 1000 pg/ml) and the ratio between Doppler early mitral inflow and tissue diastolic velocity was used to estimate LAP and was classified as low (E/e'< 15) or high (E/e' ≥ 15). A total of 69 patients with HFrEF were included; 27 had a HFS ≥ 2 and 13 of them had high NT-proBNP. HFS ≥ 2 had a 62% sensitivity, 70% specificity and a positive likelihood ratio of 2.08 (p=0.01) to detect congestion. When Val was added to clinical examination, the presence of a HFS ≥ 2 and abnormal Val showed a 100% sensitivity, 64% specificity and a positive likelihood ratio of 2.8 (p = 0.0004). Compared with LAP, the presence of HFS = 2 and abnormal Val had 86% sensitivity, 54% specificity and a positive likelihood ratio of 1.86 (p = 0.03). In conclusion, an integrated clinical examination with the addition Valsalva maneuver may improve the assessment of congestion in patients with HFrEF.

To develop and apply a detailed clinical protocol for screening and assessing subjects with a complaint of halitosis. Cross-sectional. Several methods were used to recruit subjects with a complaint of halitosis, including a newspaper advertisement. A definition of halitosis arising from within the oral cavity, which is not related to generalized chronic gingivitis, chronic periodontitis or pathology of the oral mucosa was used. An extensive list of exclusion criteria was applied at the initial visit. Eligible subjects were asked to follow strict instructions and complete a questionnaire prior to their second visit for data collection. The clinical examination consisted of an organoleptic assessment, Halimeter reading and periodontal examination. The best method of recruiting subjects was advertising. Of 66 individuals recruited, four failed to attend the screening visit and 25 were excluded. The main reasons for exclusion were poor oral hygiene and existing periodontal disease. Thirty-seven completed the full protocol, resulting in identification of 18 with halitosis and 19 controls. Application of the exclusion criteria resulted in significant attrition of eligible participants. Our results suggest that organoleptic assessment should be regarded as a useful standard for defining subjects with halitosis.

Background The rising prevalence of diabetes mellitus (DM) worldwide, especially in developing countries, and the persistence of tuberculosis (TB) as a major public health issue in these same regions, emphasize the importance of investigating this association. Here, we compared the clinical profile and disease outcomes of TB patients with or without coincident DM in a TB reference center in Brazil. Methods We performed a retrospective analysis of a TB patient cohort (treatment naïve) of 408 individuals recruited at a TB primary care center in Brazil between 2004 and 2010. Data on diagnosis of TB and DM were used to define the groups. The study groups were compared with regard to TB disease presentation at diagnosis as well as to clinical outcomes such as cure and mortality rates upon anti-tuberculosis therapy (ATT) initiation. A composite score utilizing clinical, radiological and microbiological parameters was used to compare TB severity between the groups. Results DM patients were older than non-diabetic TB patients. In addition, diabetic individuals more frequently presented with cough, night sweats, hemoptysis and malaise than those without DM. The overall pattern of lung lesions assessed by chest radiographic examination was similar between the groups. Compared to non-diabetic patients, those with TB-diabetes exhibited positive acid-fast bacilli in sputum samples more frequently at diagnosis and at 30 days after ATT initiation. Notably, higher values of the TB severity score were significantly associated with TB-diabetes comorbidity after adjustment for confounding factors. Moreover, during ATT, diabetic patients required more frequent transfers to TB reference hospitals for complex clinical management. Nevertheless, overall mortality and cure rates were indistinguishable between the study groups. Conclusions These findings reinforce the idea that diabetes negatively impacts pulmonary TB severity. Our study argues for the systematic screening for DM in TB

Clinically large cutaneous tumors and those with aggressive subclinical extension (ASE) often require wider margins and increased operative time during Mohs micrographic surgery (MMS). Our goal is to improve dermatologic surgeons' counseling information on complication risks for aggressive tumors. To examine the incidence of postoperative complications in MMS patients, with a focus on differences between aggressive and non-aggressive tumors. We performed a retrospective cross-sectional chart review of 4151 MMS cases at the University of California, San Diego. A postoperative complication was defined as an adverse event directly related to MMS reported within 6 weeks of the procedure. Clinically, large tumors had 50 times the odds of postoperative complication as compared to all other tumors (P less than 0.001). ASE was not found to be significantly associated with higher rates of postoperative complications when controlled for other factors. Clinically, large tumors may be at higher risk for complications following MMS due to their increased size and need for repair with methods other than linear closures. Tumors with ASE were not found to be at higher risk for postoperative complications. J Drugs Dermatol. 2018;17(5):511-515.

Bell palsy is a common neurologic disorder characterized by acute facial mononeuropathy of unclear cause presenting with unilateral facial weakness. Careful examination and a detailed history are important in making an accurate diagnosis. Early recognition is essential, as treatment with corticosteroids within 72 hours of onset has been shown to hasten recovery. Fortunately, most patients recover spontaneously within 3 weeks, even if untreated. Copyright © 2015 Cleveland Clinic.

Bacterial infections present a major challenge in equine medicine. Therapy should be based on bacteriological diagnosis to successfully minimize the increasing number of infections caused by multidrug-resistant bacteria. The present study is a retrospective analysis of bacteriological results from purulent infections in horses admitted at the University Equine Clinic of Bern from 2004 to 2008. From 378 samples analyzed, 557 isolates were identified, of which Staphylococcus aureus, Streptococcus equi subsp. zooepidemicus and coliforms were the most common. Special attention was paid to infections with methicillin-resistant S. aureus (MRSA) ST398 and a non-MRSA, multidrug-resistant S. aureus clone ST1 (BERN100). Screening of newly-admitted horses showed that 2.2 % were carriers of MRSA. Consequent hygiene measures taken at the Clinic helped to overcome a MRSA outbreak and decrease the number of MRSA infections.

To retrospectively evaluate the clinical behaviour and immunophenotype of lymphoma of the rectum in dogs. Eleven dogs diagnosed with lymphoma of the rectum on histopathology were retrospectively reviewed. Immunohistochemistry with CD3 and CD79a antibodies was performed at diagnosis or retrospectively. Treatment protocol varied with six dogs undergoing surgery and adjuvant chemotherapy, two received chemotherapy after only incisional biopsy, one had surgical resection only, one was treated symptomatically and one dog was not treated. Chemotherapy treatment consisted of either a -low-dose COP (cyclophosphamide - prednisolone - vincristine) protocol (four dogs) or a six-week CHOP-based (cyclophosphamide - vincristine - -prednisolone - anthracycline) protocol (four dogs). Dogs that received chemotherapy lived significantly longer than dogs that did not receive chemotherapy (2352 versus 70 days). Median survival time was not reached, and there was an overall mean survival time of 1697 days. Immunohistochemistry was performed in 10 of 11 samples, and was consistent with B-cell -lymphoma in all cases. Canine lymphoma of the rectum is associated with a favourable prognosis. Immunohistochemical evaluation of these lesions was consistent with B-cell lymphoma in all cases in which it was examined. © 2012 British Small Animal Veterinary Association.

The purpose of this retrospective study was to describe the magnetic resonance imaging (MRI) features of Poly Implant Prothèse (PIP) hydrogel implants in a group of 64 patients and to assess the incidence of rupture, compared to other clinical trials. In this double-center study, we retrospectively reviewed the data sets of 64 consecutive patients (mean age, 43±9 years, age range, 27-65 years), who underwent breast MRI examinations, between January 2008 and October 2013, with suspected implant rupture on the basis of clinical assessment or after conventional imaging examination (either mammography or ultrasound). All patients had undergone breast operation with bilateral textured cohesive gel PIP implant insertion for aesthetic reasons. The mean time after operation was 8 years (range, 6-14 years). No patients reported history of direct trauma to their implants. At the time of clinical examination, 41 patients were asymptomatic, 16 complained of breast tenderness and 7 had clinical evidence of rupture. Normal findings were observed in 15 patients. In 26 patients there were signs of mild collapse, with associated not significant peri-capsular fluid collections and no evidence of implant rupture; in 23 patients there was suggestion of implant rupture, according to breast MRI leading to an indication for surgery. In particular, 14 patients showed intra-capsular rupture, with associated evidence of the linguine sign in all cases; the keyhole sign and the droplet signs were observed in 6 cases. In 9 patients there was evidence of extra-capsular rupture, with presence of axillary collections (siliconomas) in 7 cases and peri-prosthetic and mediastinal cavity siliconomas, in 5 cases. The results of this double center retrospective study, confirm the higher incidence (36%) of prosthesis rupture observed with the PIP implants, compared to other breast implants.

Aim of the study The purpose of this retrospective study was to describe the magnetic resonance imaging (MRI) features of Poly Implant Prothèse (PIP) hydrogel implants in a group of 64 patients and to assess the incidence of rupture, compared to other clinical trials. Material and methods In this double-center study, we retrospectively reviewed the data sets of 64 consecutive patients (mean age, 43±9 years, age range, 27-65 years), who underwent breast MRI examinations, between January 2008 and October 2013, with suspected implant rupture on the basis of clinical assessment or after conventional imaging examination (either mammography or ultrasound). All patients had undergone breast operation with bilateral textured cohesive gel PIP implant insertion for aesthetic reasons. The mean time after operation was 8 years (range, 6-14 years). No patients reported history of direct trauma to their implants. Results At the time of clinical examination, 41 patients were asymptomatic, 16 complained of breast tenderness and 7 had clinical evidence of rupture. Normal findings were observed in 15 patients. In 26 patients there were signs of mild collapse, with associated not significant peri-capsular fluid collections and no evidence of implant rupture; in 23 patients there was suggestion of implant rupture, according to breast MRI leading to an indication for surgery. In particular, 14 patients showed intra-capsular rupture, with associated evidence of the linguine sign in all cases; the keyhole sign and the droplet signs were observed in 6 cases. In 9 patients there was evidence of extra-capsular rupture, with presence of axillary collections (siliconomas) in 7 cases and peri-prosthetic and mediastinal cavity siliconomas, in 5 cases. Conclusions The results of this double center retrospective study, confirm the higher incidence (36%) of prosthesis rupture observed with the PIP implants, compared to other breast implants.

Clinical inertia is a failure to intensify treatment according to evidence-based guidelines, and can have both short- and long-term adverse effects for type 2 diabetes (T2D). The aim of the present study was to demonstrate the effects of clinical inertia on glycemic control and diabetes-related complications. A retrospective cohort study was conducted at a university-based hospital in Thailand. Medical records were evaluated retrospectively from January 2010 to December 2014. Patients were classified into two groups: clinical inertia and non-inertia. Clinical inertia was defined as failure to initiate insulin within 3 months in patients with HbA1c ≥9 % who were already taking two oral antidiabetic agents. From 1206 records, 98 patients with mean HbA1c of 10.3 % were identified and enrolled in the study. The median follow-up time of these patients was 29.5 months and 68.4 % were classified into the clinical inertia group. The mean (± SD) HbA1c decrement in the clinical inertia and non-inertia groups was 0.82 ± 1.50 % and 3.02 ± 1.80 %, respectively, at 6 months (P < 0.001) and 1.46 ± 1.85 % and 3.04 ± 1.76 %, respectively, at the end of study (P < 0.001). Clinical inertia was associated with a significantly shorter median time to progression of diabetic retinopathy (DR); log rank test, P = 0.02 and a higher incidence of DR progression (10 vs 2.2 cases per 1000 person-months; P = 0.003). The adjusted incidence rate ratio for DR progression in the clinical inertia group was 4.92 (95 % confidence interval 1.11-21.77; P = 0.036). Being treated by general practitioners was the strongest risk factor associated with clinical inertia. Clinical inertia can cause persistently poor glycemic control and speed up the progression of DR in T2D. © 2016 Ruijin Hospital, Shanghai Jiaotong University School of Medicine and John Wiley & Sons Australia, Ltd.

Acute fibrinous and organizing pneumonia (AFOP) is a unique pathological entity with intra-alveolar fibrin in the form of "fibrin balls" and organizing pneumonia. It was divided into rare idiopathic interstitial pneumonia according to the classification notified by American Thoracic Society/European Respiratory Society in 2013. As a rare pathological entity, it is still not well known and recognized by clinicians. We reviewed the clinical features of 20 patients with AFOP diagnosed in a teaching hospital. The medical records of 20 patients with biopsy-proven diagnosis of AFOP were retrospectively reviewed. The patients' symptoms, duration of the disease, comorbidities, clinical laboratory data, pulmonary function testing, radiographic studies, and the response to treatment were extracted and analyzed. Fever was the most common symptom and was manifested in 90% of AFOP patients. For clinical laboratory findings, systematic inflammatory indicators, including C-reactive protein and erythrocyte sedimentation rate, were significantly higher than normal in AFOP patients. In accordance with this increased indicators, injured liver functions were common in AFOP patients. Inversely, AFOP patients had worse clinical conditions including anemia and hypoalbuminemia. For pulmonary function testing, AFOP patients showed the pattern of restrictive mixed with obstructive ventilation dysfunction. For high-resolution computerized tomography (HRCT) findings, the most common pattern for AFOP patients was lobar consolidation which was very similar to pneumonia. However, unlike pneumonia, AFOP patients responded well to glucocorticoids. Patients with AFOP manifest as acute inflammatory-like clinical laboratory parameters and lobar consolidation on HRCT, but respond well to steroid.

Indirect restorations with partial or complete occlusal surface coverage have been recommended to restore teeth with weakened walls in order to prevent cusp fracture. The success of these restorations when performed by dental students is unknown. The purpose of this retrospective study was to evaluate the clinical performance of adhesively bonded ceramic onlay restorations placed by third- and fourth-year dental students. Sixty-five ceramic onlays were placed in patients between 2009 and 2015. The onlays were laboratory or chairside fabricated with a computer-aided design and computer-aided manufacturing (CAD-CAM) system, using either IPS e.max Press or IPS e.max CAD. An adhesive technique and luting composite resin agent were used to cement the restorations. Thirty-seven onlays were evaluated clinically using the modified United States Public Health Service (USPHS) criteria. Data were statistically analyzed using the Cox proportional hazards model to compare tooth type and failures and the Fisher exact and McNemar tests to compare the USPHS criteria for significant differences (α=.05). Survival probability was calculated using the Kaplan-Meier algorithm. Five onlays were considered to be failures and needed replacement. According to the Kaplan-Meier analysis, the estimated survival rate was 96.3% after 2 years and 91.5% at 4 years. All 5 of the failures occurred on molars (13.5%) and none on premolars (P=.025). A statistically significant difference was found for marginal discoloration between onlays placed within 0 to 3 years and 3 to 6 years (P<.05) but no differences between any other criteria. Ceramic onlays placed by dental students demonstrated acceptable long-term clinical performance. Copyright © 2017 Editorial Council for the Journal of Prosthetic Dentistry. Published by Elsevier Inc.

Dengue fever (DF) is one of the most relevant human arboviral infections worldwide and has become a frequent cause of fever in the returning traveller. This retrospective study aimed to characterize epidemiological and clinical features and laboratory findings of dengue fever in German travellers. This descriptive study analyzed medical records of patients diagnosed with DF presenting at the Section of Tropical Medicine of the University Medical Centre Hamburg-Eppendorf from 2007 to 2011. Data were collected and analyzed retrospectively. In total, data of 119 DF patients (52 female, 67 male) were included in this study. The median age of the patients was 35 (range 15-75 years). DF was most frequently acquired in South-East Asia (n = 65; 54.7%), and in particular in Thailand (n = 23; 19.7%). A considerable percentage of DF infections (n = 14; 11.8%) was imported from Africa. Patients predominantly presented with fever, headache, rash, myalgia and arthralgia but also with gastrointestinal symptoms, i.e. diarrhoea. Nine patients showed signs of minor haemorrhagic manifestations. Neurological complications occurred in 13 patients. Low platelet count, leukopenia and elevated liver enzymes were the most relevant laboratory findings. Twenty patients (17.8%) had to be hospitalized. Overall, the clinical course was mostly mild to moderate, 13 patients (10.9%) showed DF warnings signs, no fatalities occurred. DF presented as a mostly mild to moderate disease in this study cohort. Outpatient treatment was adequate for the majority of patients. Still, detailed knowledge of clinical symptoms and laboratory features is essential for appropriate triage.

The aim of this retrospective clinical study was to compare the longevity of cervical restorations between resin composite (RC) and glass ionomer (GI) and to investigate variables predictive of their outcome. The clinical performance of the two restorative materials in function was compared using the ratings of the modified United States Public Health Service (USPHS) criteria. A total of 479 cervical restorations were included in the study. Ninety-one already-replaced restorations were reviewed from dental records. The other 388 restorations still in function were evaluated according to the modified USPHS criteria by two investigators. Longevity and prognostic variables were analyzed with the Kaplan-Meier survival analysis and multivariate Cox proportional hazard model. The clinical performances of the two materials were evaluated according to the ratings of the USPHS criteria and compared using the Pearson chi-square test and Fisher exact test. The longevity was not significantly different between RC and GI (median survival time, 10.4 ± 0.7 and 11.5 ± 1.1 years, respectively). The main reasons for failure were loss of retention (82.2%) and secondary caries (17.8%). The longevity of cervical restoration was significantly influenced by tooth group and operator group (Wald test, p<0.05), while material, gender, presence or absence of systemic diseases, arch, and reason for treatment did not affect the longevity. Contrary to the longevity, the clinical performance of RC was superior to GI in the criteria of retention, marginal discoloration, and marginal adaptation, but similar in secondary caries, wear, and postoperative sensitivity.

Minimal invasive plate osteosynthesis (MIPO) is one of the most important techniques in the treatment for humeral shaft fractures. This study was performed to evaluate the efficacy of MIPO technique for the treatment for humeral shaft fractures. We retrospectively evaluated 128 cases with humeral shaft fractures that were treated with MIPO technique from March 2005 to August 2008. All the patients were followed up by routine radiological imaging and clinical examinations. Constant-Murley score and HSS elbow joint score were used to evaluate the treatment outcome. The average duration of the surgery was 60 min (range 40-95 min) without blood transfusion. All fractures healed without infection. All cases recovered carrying angle except four cases with 10°-15° cubitus varus. After the average follow-up of 23 (13-38) months, satisfactory function was achieved according to Constant-Murley score and HSS elbow joint score. Constant-Murley score was 80 on average (range 68-91). According to HSS elbow joint score, there were 123 cases of excellent clinical outcome and five cases of effective outcome. It seems to be a safe and effective method for managing humeral shaft fractures with MIPO technique.

Posterior acoustic shadow width has been proposed as a more accurate measure of kidney stone size compared to direct measurement of stone width on ultrasound (US). Published data in humans to date have been based on a research using US system. Herein, we compared these two measurements in clinical US images. Thirty patient image sets where computed tomography (CT) and US images were captured less than 1 day apart were retrospectively reviewed. Five blinded reviewers independently assessed the largest stone in each image set for shadow presence and size. Shadow size was compared to US and CT stone sizes. Eighty percent of included stones demonstrated an acoustic shadow; 83% of stones without a shadow were ≤ 5 mm on CT. Average stone size was 6.5 ± 4.0 mm on CT, 10.3 ± 4.1 mm on US, and 7.5 ± 4.2 mm by shadow width. On average, US overestimated stone size by 3.8 ± 2.4 mm based on stone width (p < 0.001) and 1.0 ± 1.4 mm based on shadow width (p < 0.0098). Shadow measurements decreased misclassification of stones by 25% among three clinically relevant size categories (≤ 5, 5.1-10, > 10 mm), and by 50% for stones ≤ 5 mm. US overestimates stone size compared to CT. Retrospective measurement of the acoustic shadow from the same clinical US images is a more accurate reflection of true stone size than direct stone measurement. Most stones without a posterior shadow are ≤ 5 mm.

The aim of this retrospective study was to evaluate the effectiveness of laser therapy for acceleration and recovery of nerve sensitivity after orthognathic or minor oral surgeries, by analysis of clinical records of patients treated at the Special Laboratory of Lasers in Dentistry (LELO, School of Dentistry, University of São Paulo), throughout the period 2007-2013. Nerve tissue lesions may occur during various dental and routine surgical procedures, resulting in paresthesia. Laser therapy has been shown to be able to accelerate and enhance the regeneration of the affected nerve tissue; however, there are few studies in the literature that evaluate the effects of treatment with low-power laser on neural changes after orthognathic or minor oral surgeries. A total of 125 clinical records were included, and the data on gender, age, origin of the lesion, nerve, interval between surgery and onset of laser therapy, frequency of laser irradiation (one or two times per week), final evolution, and if there was a need to change the irradiation protocol, were all recorded. These data were related to the recovery of sensitivity in the affected nerve area. Descriptive analyses and modeling for analysis of categorical data (α=5%) were performed. The results from both analyses showed that the recovery of sensitivity was correlated with patient age (p=0.015) and interval between surgery and onset of laser therapy (p=0.002). Within the limits of this retrospective study, it was found that low- power laser therapy with beam emission band in the infrared spectrum (808 nm) can positively affect the recovery of sensitivity after orthognathic or minor oral surgeries.

Assessing test performance validity is a standard clinical practice and although studies have examined the utility of cognitive/memory measures, few have examined attention measures as indicators of performance validity beyond the Reliable Digit Span. The current study further investigates the classification probability of embedded Performance Validity Tests (PVTs) within the Brief Test of Attention (BTA) and the Conners' Continuous Performance Test (CPT-II), in a large clinical sample. This was a retrospective study of 615 patients consecutively referred for comprehensive outpatient neuropsychological evaluation. Non-credible performance was defined two ways: failure on one or more PVTs and failure on two or more PVTs. Classification probability of the BTA and CPT-II into non-credible groups was assessed. Sensitivity, specificity, positive predictive value, and negative predictive value were derived to identify clinically relevant cut-off scores. When using failure on two or more PVTs as the indicator for non-credible responding compared to failure on one or more PVTs, highest classification probability, or area under the curve (AUC), was achieved by the BTA (AUC = .87 vs. .79). CPT-II Omission, Commission, and Total Errors exhibited higher classification probability as well. Overall, these findings corroborate previous findings, extending them to a large clinical sample. BTA and CPT-II are useful embedded performance validity indicators within a clinical battery but should not be used in isolation without other performance validity indicators.

Introduction: Oral lichen planus (OLP) is a relatively common inflammatory mucocutaneous disorder that frequently involves the oral mucosa. The clinical presentation of OLP ranges from mild painless white keratotic lesions to painful erosions and ulcerations. An important complication of OLP is the development of oral squamous cell carcinoma, which led the World Health Organization (WHO) to classify OLP as a potentially malignant disorder. The demographic and clinical characteristics of OLP have been well-described in several relatively large series from developed countries, whereas such series from developing countries are rare. Objective: The objective of this retrospective study was to investigate the epidemiological and clinical characteristics of 128 OLP patients in rural population of India. Materials and Methods: In this study, the diagnostic criteria proposed by van der Meij et al. in 2003 based on the WHO definition of OLP were used to identify cases. Results: In 128 patients, M:F ratio was 1.61:1. The buccal mucosa was the most common site (88.20%). White lichen was seen in 83.59% and red lichen in 16.40% cases. Reticular type of OLP was the most common form (83.5%) followed by erosive (15.6%) and atrophic OLP (0.78%). The incidence of systemic diseases included hypertension (11%), diabetes mellitus (2.4%), and hypothyroidism (0.78%). Histopathologically epithelial dysplasia was present in 4 cases. Conclusion: Most of the characteristics are consistent with previous studies with differences in few. Lichen planus is a chronic disease where treatment is directed to control of symptoms. Long-term follow-up is essential to monitor for symptomatic flare ups and possible malignant transformation. PMID:24015006

To investigate the correlation between the preoperative biometric parameters of the anterior segment and the vault after implantable Collamer lens (ICL) implantation via this retrospective study. Retrospective clinical study. A total of 78 eyes from 41 patients who underwent ICL implantation surgery were included in this study. Preoperative biometric parameters, including white-to-white (WTW) diameter, central corneal thickness, keratometer, pupil diameter, anterior chamber depth, sulcus-to-sulcus diameter, anterior chamber area (ACA) and central curvature radius of the anterior surface of the lens (Lenscur), were measured. Lenscur and ACA were measured with Rhinoceros 5.0 software on the image scanned with ultrasound biomicroscopy (UBM). The vault was assessed by UBM 3 months after surgery. Multiple stepwise regression analysis was employed to identify the variables that were correlated with the vault. The results showed that the vault was correlated with 3 variables: ACA (22.4 ± 4.25 mm2), WTW (11.36 ± 0.29 mm) and Lenscur (9.15 ± 1.21 mm). The regressive equation was: vault (mm) = 1.785 + 0.017 × ACA + 0.051 × Lenscur - 0.203 × WTW. Biometric parameters of the anterior segment (ACA, WTW and Lenscur) can predict the vault after ICL implantation using a new regression equation. © 2016 The Author(s) Published by S.

The clinical breast examination (CBE) is performed to detect breast pathology. However, little is known regarding clinical technique and how it relates to diagnostic accuracy. We sought to quantify breast examination search patterns and hand utilization with a new data collection and analysis system. Participants performed the CBE while the sensor mapping and video camera system collected performance data. From this data, algorithms were developed that measured the number of hands used during the exam and active examination time. This system is a feasible and reliable method to collect new information on CBE techniques.

2017-01-01

Background Insomnia frequently occurs to patients with persistent back pain. By worsening pain, mood, and physical functioning, insomnia could lead to the negative clinical consequences of patients with failed back surgery syndrome (FBSS). This retrospective and cross-sectional study aims to identify the risk factors associated with clinical insomnia in FBSS patients. Methods A total of 194 patients with FBSS, who met the study inclusion criteria, were included in this analysis. The Insomnia Severity Index (ISI) was utilized to ascertain the presence of clinical insomnia (ISI score ≥ 15). Logistic regression analysis evaluates patient demographic factors, clinical factors including prior surgical factors, and psychological factors to identify the risk factors of clinical insomnia in FBSS patients. Results After the persistent pain following lumbar spine surgery worsened, 63.4% of patients reported a change from mild to severe insomnia. In addition, 26.2% of patients met the criteria for clinically significant insomnia. In a multivariate logistic regression analysis, high pain intensity (odds ratio (OR) =2.742, 95% confidence interval (CI): 1.022 - 7.353, P =0.045), high pain catastrophizing (OR=4.185, 95% CI: 1.697 - 10.324, P =0.002), greater level of depression (OR =3.330, 95% CI: 1.127 - 9.837, P =0.030) were significantly associated with clinical insomnia. However, patient demographic factors and clinical factors including prior surgical factors were not significantly associated with clinical insomnia. Conclusions Insomnia should be addressed as a critical part of pain management in FBSS patients with these risk factors, especially in patients with high pain catastrophizing.

Event-related potentials in impulsively aggressive juveniles: a retrospective chart-review study.

The assessment, treatment and management of aggressive youth represent a major clinical challenge facing pediatric mental health professionals today. Although a number of studies have examined physiological differences among aggressive patients vs. controls, the current literature lacks a comprehensive examination of the electroencephalographic activity of impulsively aggressive juveniles. The current study was designed to fill this void in the literature via a retrospective chart review of 80 male and female juveniles undergoing inpatient treatment for pathologically impulsive aggression. Clinical reports for mid- and late-latency event-related potentials (ERPs) were examined to determine their correlations with aggression characteristics, as well as any differential predictive utility of hemispheric differences and auditory vs. visual potentials. Results indicated that decrements of mid-latency potentials and ERPs evoked by auditory stimuli (vs. late-latency components and visual ERPs) were more highly predictive of aggressive behavior. No significant hemispheric differences were noted. Taken together, these results have theoretical significance for the etiology of impulsive aggression, and perhaps also clinical relevance for the treatment of this condition.

Grzybicki, D M; Callaghan, E J; Raab, S S

1998-09-01

Given the virtual absence of histologically detected, clinically unsuspected disease in intervertebral disc specimens, some authors have advocated that histological examination be discontinued. However, the examination of intervertebral disc specimens remains common practice in most pathology laboratories. No cost-benefit analysis of this practice has been made; therefore, the authors' goal in this study was perform such an analysis. Using the University of Iowa surgical pathology database, 1109 patients who had undergone a laminectomy were identified retrospectively. These cases were classified into four categories based on the patients' preoperative clinical diagnosis and final histopathological diagnosis: insignificant clinical diagnosis/insignificant pathological diagnosis (ICIP), significant clinical diagnosis/insignificant pathological diagnosis (SCIP), significant clinical diagnosis/significant pathological diagnosis (SCSP), and insignificant clinical diagnosis/significant pathological diagnosis (ICSP). A significant clinical diagnosis was defined as one other than a benign, noninfectious indication for laminectomy. A significant pathological diagnosis was a diagnosis other than degenerative changes. The cost-benefit value of performing a histological examination in cases with significant or insignificant clinical diagnoses was examined. The cases were classified as: 1068 ICIP, 17 SCIP, 21 SCSP, and three ICSP. On chart review, in all three cases of ICSP an epidural abscess was identified perioperatively and the subsequent histological diagnosis did not affect patient care. The costs per case of identifying a significant pathological diagnosis with a significant and an insignificant clinical diagnosis were $44.79 and $8811, respectively. Histological examination of intervertebral disc specimens is cost beneficial only if there is a significant preoperative clinical diagnosis.

Physical Examination for the Academic Psychiatrist: Primer and Common Clinical Scenarios.

PubMed

Azzam, Pierre N; Gopalan, Priya; Brown, Jennifer R; Aquino, Patrick R

2016-04-01

As clinical psychiatry has evolved to mirror the patient care model followed in other medical specialties, psychiatrists are called upon increasingly to utilize general medical skills in routine practice. Psychiatrists who practice in academic settings are often required to generate broad differential diagnoses that include medical and neurologic conditions and, as a result, benefit from incorporating physical examination into their psychiatric assessments. Physical examination allows psychiatrists to follow and to teach patient-informed clinical practices and comprehensive treatment approaches. In this commentary, the authors encourage routine use of a targeted physical examination and outline common scenarios in which physical examination would be useful for the academic psychiatrist: delirium, toxidromes, and unexplained medical conditions (e.g., somatic symptom disorders).

The biasing effect of clinical history on physical examination diagnostic accuracy.

PubMed

Sibbald, Matthew; Cavalcanti, Rodrigo B

2011-08-01

Literature on diagnostic test interpretation has shown that access to clinical history can both enhance diagnostic accuracy and increase diagnostic error. Knowledge of clinical history has also been shown to enhance the more complex cognitive task of physical examination diagnosis, possibly by enabling early hypothesis generation. However, it is unclear whether clinicians adhere to these early hypotheses in the face of unexpected physical findings, thus resulting in diagnostic error. A sample of 180 internal medicine residents received a short clinical history and conducted a cardiac physical examination on a high-fidelity simulator. Resident Doctors (Residents) were randomised to three groups based on the physical findings in the simulator. The concordant group received physical examination findings consistent with the diagnosis that was most probable based on the clinical history. Discordant groups received findings associated with plausible alternative diagnoses which either lacked expected findings (indistinct discordant) or contained unexpected findings (distinct discordant). Physical examination diagnostic accuracy and physical examination findings were analysed. Physical examination diagnostic accuracy varied significantly among groups (75 ± 44%, 2 ± 13% and 31 ± 47% in the concordant, indistinct discordant and distinct discordant groups, respectively (F(2,177)  = 53, p < 0.0001). Of the 115 Residents who were diagnostically unsuccessful, 33% adhered to their original incorrect hypotheses. Residents verbalised an average of 12 findings (interquartile range: 10-14); 58 ± 17% were correct and the percentage of correct findings was similar in all three groups (p = 0.44). Residents showed substantially decreased diagnostic accuracy when faced with discordant physical findings. The majority of trainees given discordant physical findings rejected their initial hypotheses, but were still diagnostically unsuccessful. These results

The purpose of this study was to assess the clinical and radiographic outcomes of a 1-minute application of full-strength Buckley's formocresol with concurrent hemostasis using the medicated cotton pledget in human primary teeth. Using a retrospective chart review, clinical and radiographic data were available for 557 primary molars in 320 patients. Descriptive statistics and survival analysis were used to assess outcomes. Overall clinical success, radiographic success, and cumulative 5-year survival rates were approximately 99%, 90%, and 87%, respectively. Internal root resorption (∼5%) and pulp canal obliteration (∼2%) were the most frequently observed radiographic failures. Thirty-nine teeth were extracted due to clinical and or radiographic failure. Mandibular molars were 6 times more prone to radiographic failure than maxillary molars. Success rates for the modified technique are comparable to techniques that use the 5-minute diluted or full-strength solutions reported in the literature. This 1-minute full-strength formocresol technique is an acceptable alternative to published traditional techniques.

We performed a retrospective analysis of clinical and laboratory data over 5 years in a tertiary centre to assess clinical and microbiological characteristics of patients with Raoultella spp. infection. Raoultella spp. were deemed responsible for clinical infections in 57 patients (R. planticola, n = 32 and R. ornithinolytica, n = 25). The most prevalent diagnoses for R. planticola were cystitis (50%; n = 16) followed by bacteraemia and pneumonia (9.4%; n = 3); for R. ornithinolytica, cystitis (36%; n = 9) followed by pneumonia (24%; n = 6). Immunodeficiency was present in 18 patients (56.3%) with R. planticola and in 16 patients (64%) with R. ornithinolytica infection. Of these, 55.6% and 37.5% had diabetes and 27.8% and 18.% were solid organ transplant recipients, respectively. All isolates were sensitive to third-generation cephalosporins, fluoroquinolones and aminoglycosides. Mortality of infections with R. planticola (n = 5; 15.6%) was higher than for R. ornithinolytica (n = 2; 8.0%), but the difference was not statistically significant.

Evaluation of 1-year safety profile of intravitreal ranibizumab 0.5 mg in neovascular age-related macular degeneration (NV-AMD) within routine clinical practice. The LUMINOUS programme comprises a prospective observational study assessing ranibizumab 'real-world' safety and clinical effectiveness across licensed indications worldwide and an annual retrospective pooled safety analysis from completed NV-AMD ranibizumab registries. 1-year data from four European registries are available. This retrospective pooled safety analysis assessed 1-year incidence rates for safety events of particular interest (key ocular or systemic events possibly related to the injection procedure or vascular endothelial growth factor inhibition) together with treatment exposure. Patients were treated according to local protocols within the ranibizumab licence. Data of 4444 patients from registries in Germany (n=3470), the Netherlands (n=243), Belgium (n=260) and Sweden (n=471) were retrospectively pooled. Between 70.4% and 84.4% of enrolled patients completed 1 year of follow-up. Most frequent overall ocular events of particular interest were retinal pigment epithelial tears (27 patients; <1%) and intraocular pressure-related events (12 patients; <0.3%). Most frequent non-ocular event of particular interest was stroke (19 patients; 0.4%); annual incidence of stroke was low across all registries (0.0-0.5%). Ranibizumab demonstrated favourable 1-year safety profile for NV-AMD in this routine clinical practice sample, consistent with previous reported trial data. Additional data from a larger patient population are needed to better describe the long-term safety profile of ranibizumab in routine clinical practice and further evaluate risk for infrequent but serious events in 'real-life' settings. The 5-year LUMINOUS prospective observational study will address this need.

There are many difficulties in undertaking independent clinical research without support from the pharmaceutical industry. In this retrospective observational study, some design characteristics, the clinical trial public register and the publication rate of noncommercial clinical trials were compared to those of commercial clinical trials. A total of 809 applications of drug-evaluation clinical trials were submitted from May 2004 to May 2009 to the research ethics committee of a tertiary hospital, and 16.3% of trials were noncommercial. They were mainly phase IV, multicentre national, and unmasked controlled trials, compared to the commercial trials that were mainly phase II or III, multicentre international, and double-blind masked trials. The commercial trials were registered and published more often than noncommercial trials. More funding for noncommercial research is still needed. The results of the research, commercial or noncommercial, should be disseminated in order not to compromise either its scientific or its social value. © 2018 The British Pharmacological Society.

Physical examination of the abdomen is an essential skill. Knowledge of its clinical anatomy and application is vital for making diagnoses. Misinterpretation of anatomy during examination can have serious consequences. This review addresses understanding of the anatomy, methodology, and complications of abdominal physical examination. It includes particular reference to modern technology and investigations. Physical examination is performed for diagnostic purposes. However, the art of physical examination is declining as more and more clinicians rely on newer technology. This can have regrettable consequences: negligence, waste of time and resources, and deterioration of clinical skills. With a sound knowledge of clinical anatomy, and realization of the importance of physical examination of the abdomen, clinician, and patients alike can benefit. Clin.

The objective of this retrospective study was to determine whether patients undergoing in vitro fertilization (IVF) benefit from reducing the gamete co-incubation time. Patients (n = 570) were enrolled, including 281 patients in the reduced incubation time group (2-h incubation) and 289 patients in the standard IVF group (18-h incubation). The observed outcomes, including the clinical pregnancy rate (CPR), implantation rate (IR), live birth rate (LBR), and miscarriage rate (MR), were similar between the two groups. When the data were divided into two subgroups based on the maternal age (≤30 and >30 years), the rates of top-quality embryos (30.83 vs. 25.89 %; p = 0.028), CPR (66.67 vs. 42.11 %; p = 0.013), and IR (41.90 vs. 31.25 %, p = 0.019) of the 2-h incubation group were significantly higher in the younger subgroup. However, for older patients, only a lower MR (7.59 vs. 20.83 %; p = 0.019) was achieved. Reducing the time of incubation still improved the CPR (OR = 1.993, 95 % CI 1.141-3.480) and MR (OR = 3.173, 95 % CI 1.013-9.936) in the younger and older subgroups, respectively, after it was adjusted for potential confounders. Reducing incubation time improves the clinical results of IVF, although the LBR is not statistically different between the 2- and 18-h incubation time groups. And the specific clinical outcomes of reducing incubation time varied between the >30-year-old and the ≤30-year-old.

In this paper we sought to reproduce, as a computational retrospective study in an EHR database (MIMIC-II), a recent large prospective clinical study: the 2013 publication, by the Japanese Association for Acute Medicine (JAAM), about disseminated intravascular coagulation, in the journal Critical Care (PMID: 23787004). We designed in SQL and Java a set of electronic phenotypes that reproduced the study's data sampling, and used R to perform the same statistical inference procedures. All produced source code is available online at https://github.com/fabkury/paamia2015. Our program identified 2,257 eligible patients in MIMIC-II, and the results remarkably agreed with the prospective study. A minority of the needed data elements was not found in MIMIC-II, and statistically significant inferences were possible in the majority of the cases.

To review the clinical and diagnostic findings and survival of dilated cardiomyopathy from a large population of dogs in England. A retrospective study of the case records of dogs with dilated cardiomyopathy collected between January 1993 and May 2006. There were 369 dogs with dilated cardiomyopathy of which all were pure-bred dogs except for four. The most commonly affected breeds were dobermanns and boxers. Over 95 per cent of dogs weighed more than 15 kg and 73 per cent were male. The median duration of signs before referral was three weeks with 65 per cent presenting in stage 3 heart failure. The most common signs were breathlessness (67 per cent) and coughing (64 per cent). The majority of dogs (89 per cent) had an arrhythmia at presentation and 74 per cent of dogs had radiographic signs of pulmonary oedema or pleural effusion. The median survival time was 19 weeks. Dilated cardiomyopathy occurs primarily in medium to large breed pure-bred dogs, and males are more frequently affected than females. The duration of clinical signs before referral is often short and the survival times are poor. Greater awareness of affected breeds, clinical signs and diagnostic findings may help in early recognition of this disease which often has a short clinical phase.

Modelling and simulation may become clinically applicable tools for detailed evaluation of the cardiovascular system and clinical decision-making to guide therapeutic intervention. Models based on pressure-volume relationship and zero-dimensional representation of the cardiovascular system may be a suitable choice given their simplicity and versatility. This approach has great potential for application in heart failure where the impact of left ventricular assist devices has played a significant role as a bridge to transplant and more recently as a long-term solution for non eligible candidates. We sought to investigate the value of simulation in the context of three heart failure patients with a view to predict or guide further management. CARDIOSIM © was the software used for this purpose. The study was based on retrospective analysis of haemodynamic data previously discussed at a multidisciplinary meeting. The outcome of the simulations addressed the value of a more quantitative approach in the clinical decision process. Although previous experience, co-morbidities and the risk of potentially fatal complications play a role in clinical decision-making, patient-specific modelling may become a daily approach for selection and optimisation of device-based treatment for heart failure patients. Willingness to adopt this integrated approach may be the key to further progress.

Telemedicine and telehealth are the practices of medicine at a distance. Performing the equivalent of a complete clinical examination by telemedicine would be unusual. However, components of a more traditional clinical examination are part of the telemedicine workup for specific conditions. Telemedicine clinical examinations are facilitated, and enhanced, through the integration of a class of medical devices referred to as telemedicine peripherals (eg, electronic stethoscopes, tele-ophthalmoscopes, video-otoscopes, and so forth). Direct-to-consumer telehealth is a rapidly expanding segment of the health care service industry. Copyright © 2018 Elsevier Inc. All rights reserved.

The rational clinical examination. Does this patient have strep throat?

Sore throat is a common complaint, and identifying patients with group A beta-hemolytic streptococcal pharyngitis (strep throat) is an important task for clinicians. Previous reviews have not systematically reviewed and synthesized the evidence. To review the precision and accuracy of the clinical examination in diagnosing strep throat. MEDLINE search for articles about diagnosis of strep throat using history-taking and physical examination. Large blinded, prospective studies (having > or =300 patients with sore throat) reporting history and physical examination data and using throat culture as the reference standard were included. Of 917 articles identified by the search, 9 met all inclusion criteria. Pairs of authors independently reviewed each article and used consensus to resolve discrepancies. The most useful findings for evaluating the likelihood of strep throat are presence of tonsillar exudate, pharyngeal exudate, or exposure to strep throat infection in the previous 2 weeks (positive likelihood ratios, 3.4, 2.1, and 1.9, respectively) and the absence of tender anterior cervical nodes, tonsillar enlargement, or exudate (negative likelihood ratios, 0.60, 0.63, and 0.74, respectively). No individual element of history-taking or physical examination is accurate enough by itself to rule in or rule out strep throat. Three validated clinical prediction rules are described for adult and pediatric populations. While no single element of history-taking or physical examination is sufficiently accurate to exclude or diagnose strep throat, a well-validated clinical prediction rule can be useful and can help physicians make more informed use of rapid antigen tests and throat cultures.

Does Changing Examiner Stations During UK Postgraduate Surgery Objective Structured Clinical Examinations Influence Examination Reliability and Candidates' Scores?

2016-01-01

Objective structured clinical examinations (OSCE) are widely used for summative assessment in surgery. Despite standardizing these as much as possible, variation, including examiner scoring, can occur which may affect reliability. In study of a high-stakes UK postgraduate surgical OSCE, we investigated whether examiners changing stations once during a long examining day affected marking, reliability, and overall candidates' scores compared with examiners who examined the same scenario all day. An observational study of 18,262 examiner-candidate interactions from the UK Membership of the Royal College of Surgeons examination was carried at 3 Surgical Colleges across the United Kingdom. Scores between examiners were compared using analysis of variance. Examination reliability was assessed with Cronbach's alpha, and the comparative distribution of total candidates' scores for each day was evaluated using t-tests of unit-weighted z scores. A significant difference was found in absolute scores differences awarded in the morning and afternoon sessions between examiners who changed stations at lunchtime and those who did not (p < 0.001). No significant differences were found for the main effects of either broad content area (p = 0.290) or station content area (p = 0.450). The reliability of each day was not affected by examiner switching (p = 0.280). Overall, no difference was found in z-score distribution of total candidate scores and categories of examiner switching. This large study has found that although the range of marks awarded varied when examiners change OSCE stations, examination reliability and the likely candidate outcome were not affected. These results may have implications for examination design and examiner experience in surgical OSCEs and beyond. Copyright © 2016 Association of Program Directors in Surgery.

The aim of the present study was to retrospectively evaluate women who were admitted to Hiroshima University Hospital, Department of Psychiatry and Neurosciences, from 1979 to 2008. The women were classified as 'depressed women' (n = 159; mean age, 52.3 +/- 5.7 years) or 'non-depressed women' (n = 182; mean age, 51.5 +/- 4.5 years). A total of 14.5% of the depressed women and 3.3% of the non-depressed women had a hysterectomy and/or oophorectomy; this difference was statistically significant (P = 0.0003). This is consistent with previous reported information as well as clinical experience that depressed women had a higher incidence of hysterectomy and/or oophorectomy.

About 30% of cases of chronic lymphocytic leukaemia (CLL) carry quasi-identical B-cell receptor immunoglobulins and can be assigned to distinct stereotyped subsets. Although preliminary evidence suggests that B-cell receptor immunoglobulin stereotypy is relevant from a clinical viewpoint, this aspect has never been explored in a systematic manner or in a cohort of adequate size that would enable clinical conclusions to be drawn. For this retrospective, multicentre study, we analysed 8593 patients with CLL for whom immunogenetic data were available. These patients were followed up in 15 academic institutions throughout Europe (in Czech Republic, Denmark, France, Greece, Italy, Netherlands, Sweden, and the UK) and the USA, and data were collected between June 1, 2012, and June 7, 2013. We retrospectively assessed the clinical implications of CLL B-cell receptor immunoglobulin stereotypy, with a particular focus on 14 major stereotyped subsets comprising cases expressing unmutated (U-CLL) or mutated (M-CLL) immunoglobulin heavy chain variable genes. The primary outcome of our analysis was time to first treatment, defined as the time between diagnosis and date of first treatment. 2878 patients were assigned to a stereotyped subset, of which 1122 patients belonged to one of 14 major subsets. Stereotyped subsets showed significant differences in terms of age, sex, disease burden at diagnosis, CD38 expression, and cytogenetic aberrations of prognostic significance. Patients within a specific subset generally followed the same clinical course, whereas patients in different stereotyped subsets-despite having the same immunoglobulin heavy variable gene and displaying similar immunoglobulin mutational status-showed substantially different times to first treatment. By integrating B-cell receptor immunoglobulin stereotypy (for subsets 1, 2, and 4) into the well established Döhner cytogenetic prognostic model, we showed these, which collectively account for around 7% of all

Purpose Evaluation of 1-year safety profile of intravitreal ranibizumab 0.5 mg in neovascular age-related macular degeneration (NV-AMD) within routine clinical practice. Methods The LUMINOUS programme comprises a prospective observational study assessing ranibizumab ‘real-world’ safety and clinical effectiveness across licensed indications worldwide and an annual retrospective pooled safety analysis from completed NV-AMD ranibizumab registries. 1-year data from four European registries are available. This retrospective pooled safety analysis assessed 1-year incidence rates for safety events of particular interest (key ocular or systemic events possibly related to the injection procedure or vascular endothelial growth factor inhibition) together with treatment exposure. Patients were treated according to local protocols within the ranibizumab licence. Results Data of 4444 patients from registries in Germany (n=3470), the Netherlands (n=243), Belgium (n=260) and Sweden (n=471) were retrospectively pooled. Between 70.4% and 84.4% of enrolled patients completed 1 year of follow-up. Most frequent overall ocular events of particular interest were retinal pigment epithelial tears (27 patients; <1%) and intraocular pressure-related events (12 patients; <0.3%). Most frequent non-ocular event of particular interest was stroke (19 patients; 0.4%); annual incidence of stroke was low across all registries (0.0–0.5%). Conclusions Ranibizumab demonstrated favourable 1-year safety profile for NV-AMD in this routine clinical practice sample, consistent with previous reported trial data. Additional data from a larger patient population are needed to better describe the long-term safety profile of ranibizumab in routine clinical practice and further evaluate risk for infrequent but serious events in ‘real-life’ settings. The 5-year LUMINOUS prospective observational study will address this need. PMID:23850682

Objective: To evaluate the clinical characteristics and etiologies of central diabetes insipidus (CDI). Methods: The clinical data of 230 patients with CDI in the Department of Endocrinology of Chinese PLA General Hospital from 2008 June to 2014 December were collected and analyzed retrospectively. Results: The three most common causes of CDI were idiopathic CDI, lymphocytic hypophysitis and intracranial germ cell tumors. Among all the CDI, the idiopathic CDI accounted for 37.48%. There were significant differences in age onset and gender distribution among the different causes of CDI. The patients with intracranial germ cell tumors [age of onset(19.2±10.2) years] were younger than the other types of CDI. Germ cell tumors patients were more common in male, and lymphocytic hypophysitis patients were more common in female. The most frequent abnormality of anterior pituitary in patients with CDI was growth hormone deficiency, followed by hypogonadism, adrenal insufficiency and hypothyroidism. The dysfunction of thyroid axis and adrenal axis in patients with germ cell tumor was more common than those in patients with idiopathic and lymphocytic hypophysitis. Conclusions: The most common causes of central diabetes insipidus were idiopathic CDI, lymphocytic hypophysitis and intracranial germ cell tumors. There were differences in age of onset, gender distribution and abnormal production of anterior pituitary hormones among all causes of CDI patients.

Objective. To evaluate how effectively pharmacy students and practicing pharmacists communicate and apply knowledge to simulations of commonly encountered patient scenarios using an objective structured clinical examination (OSCE). Design. Second-, third-, and fourth-year pharmacy students completed an OSCE as part of their required courses in 2012 and 2013. All students in both years completed identical OSCE cases. Licensed pharmacists were recruited to complete the OSCE and serve as controls in 2012. A survey assessed student perception and acceptance of the OSCE as well as student confidence in performance. Assessment. Licensed pharmacists had significantly higher clinical and communication skills scores than did pharmacy students. Student progression in communication and clinical skills improved significantly over time. Survey results indicated that students felt the OSCE was well-structured and assessed clinical skills taught in pharmacy school; 86% of students felt confident they could provide these skills. Conclusion. Objective structured clinical examinations can evaluate clinical competence and communication skills among professional students. Implementation of OSCEs may be an effective tool for assessment of the Center for the Advancement of Pharmacy Education domains.

Prospective cross-sectional study. To examine the radiological and physical therapy diagnoses of lateral hip pain (LHP), and determine the validity of selected clinical variables for predicting gluteal tendon pathology. LHP is frequently encountered by clinicians. Further investigation is required to establish the specific pathologies implicated in the cause of LHP, and which clinical tests are useful in the assessment of this problem. Forty patients with unilateral LHP underwent a physical therapy examination followed by magnetic resonance imaging (MRI) studies. Three radiologists analyzed the images of both hips for signs of pathology. Interobserver reliability of the image analyses, the agreement between the physical therapy and radiological diagnoses, and the validity of the clinical tests were examined. Gluteus medius tendon pathology, bursitis, osteoarthritis and gluteal muscle atrophy (predominantly affecting gluteus minimus) were all implicated in the imaging report of LHP. While prevalent in symptomatic hips, abnormalities were also identified in asymptomatic hips, particularly relating to the diagnosis of bursitis. The strength of agreement between radiologists was variable and little agreement existed between the physical therapy and radiological diagnoses of pathology. Nine of the 26 clinical variables examined in relation to gluteal tendon pathology had likelihood ratios above 2.0 or below 0.5, but the associated 95% confidence intervals were large. The diagnosis of LHP is challenging and our results highlight some problems associated with the use of MRI as a diagnostic reference standard. This factor, together with the imprecise point estimates of the likelihood ratios, means that no firm conclusions can be made regarding the diagnostic utility of the clinical tests used in the assessment of gluteal tendon pathology.

Objective Clinical management issues are contributory factors to mortality. The aim of this study was to use data from the Victorian Audit of Surgical Mortality (VASM), an educational peer-review process for surgeons, to discover differences in the incidence of these issues between surgical specialties in order to focus attention to areas of care that might be improved. Design This study used retrospectively analysed observational data from VASM. Clinical management issues between eight specialties were assessed using χ2 analysis. Data sources VASM data were reported by participating public and private health services, the Coroner and self-reporting surgeons across Victoria. Results A total of 2946 specific clinical issues as deficiencies of care were reported. 15% of cases had significant issues of care. The most common clinical management issue was the delay in delivery of treatment. Other clinical issues included the quality of communication and documentation, preoperative and postoperative care, adverse events and protocol issues. There were significant differences in issues between specialties. Conclusions The clinical management issues presented across surgical specialties were similar; however, five issues of clinical care differed significantly in frequency across surgical specialties. The three main issues varying among specialties were complications after operation, communication and postoperative care. Addressing these clinical management issues via the peer-review process may impact positively on patient care. PMID:24980043

Healthcare-associated pneumonia (HCAP) is associated with drug-resistant pathogens and high mortality, and there is no clear evidence that this is due to inappropriate antibiotic therapy. This study was to elucidate the clinical features, pathogens, therapy, and outcomes of HCAP, and to clarify the risk factors for drug-resistant pathogens and prognosis. Retrospective observational study among hospitalized patients with HCAP over 10 years. The primary outcome was 30-day all-cause hospital mortality after admission. Demographics (age, gender, clinical features, and comorbidities), dates of admission, discharge and/or death, hospitalization costs, microbiological results, chest imaging studies, and CURB-65 were analyzed. Antibiotics, admission to Intensive Care Unit (ICU), mechanical ventilation, and pneumonia prognosis were recorded. Patients were dichotomized based on CURB-65 (low- vs. high-risk). Among 612 patients (mean age of 70.7 years), 88.4% had at least one comorbidity. Commonly detected pathogens were Acinetobacter baumannii, Pseudomonas aeruginosa, and coagulase-negative staphylococci. Initial monotherapy with β-lactam antibiotics was the most common initial therapy (50%). Mean age, length of stay, hospitalization expenses, ICU admission, mechanical ventilation use, malignancies, and detection rate for P. aeruginosa, and Staphylococcus aureus were higher in the high-risk group compared with the low-risk group. CURB-65 ≥3, malignancies, and mechanical ventilation were associated with an increased mortality. Logistic regression analysis showed that cerebrovascular diseases and being bedridden were independent risk factors for HCAP. Initial treatment of HCAP with broad-spectrum antibiotics could be an appropriate approach. CURB-65 ≥3, malignancies, and mechanical ventilation may result in an increased mortality.

The objective structured clinical skills examination (OSCE) has over the years emerged as a method of evaluating clinical skills in most medical and allied professions. Although its validity and objectivity has evoked so much debate in the literature, little has been written about its application in non-traditional education systems such as in distance learning. This study examined clinical skills competence among practising nursing students who were enrolled in a distance learning programme. The study examined the effect of work and years of nursing practice on nurses' clinical skills competence. This study used observational design whereby nursing students' clinical skills were observed and scored in five OSCE stations. Two instruments were used for the data collection - A self-administered questionnaire on the students' bio-demographic data, and a check list on the clinical skills which the examiners rated on a four point scale. The findings revealed that 14% of the nurses had level four competence, which indicated that they could perform the tasks correctly and complete. However, 12% failed the OSCE, even though they had more than 10 years experience in nursing and post basic qualifications. Inter-rater reliability was 0.92 for the five examiners. Factor analysis indicated that five participant factors accounted for 74.1% of the variations in clinical skills performance. An OSCE is a necessary assessment tool that should be continuously applied in nursing education, regardless of the mode of the education program, the student's years of experience or his/her clinical placement. This study validates the need for OSCE in both the design of tertiary nursing degree programs and the assessment of nurses' clinical competency level.

Objective To determine the association between family-centered rounds (FCR) and medical student knowledge acquisition as assessed by the National Board of Medical Examiners (NBME) pediatric subject (shelf) exam. Methods A retrospective cohort study was conducted of third-year medical students who graduated from Virginia Commonwealth University School of Medicine between 2009 and 2014. This timeframe represented the transition from 'traditional' rounds to FCR on the pediatric inpatient unit. Data collected included demographics, United States Medical Licensing Examination (USMLE) Step 1 and 2 scores, and NBME subject examinations in pediatrics (PSE), medicine (MSE), and surgery (SSE). Results Eight hundred and sixteen participants were included in the analysis. Student performance on the PSE could not be statistically differentiated from performance on the MSE for any year except 2011 (z-score=-0.17, p=0.02). Average scores on PSE for years 2009, 2010, 2013, and 2014 were significantly higher than for SSE, but not significantly different for all other years. The PSE was highly correlated with USMLE Step 1 and Step 2 examinations (correlation range 0.56-0.77) for all years. Conclusions Our results showed no difference in PSE performance during a time in which our institution transitioned to FCR. These findings should be reassuring for students, attending physicians, and medical educators.

Enzyme replacement therapy (ERT) with laronidase, (recombinant human α-L-iduronidase; Aldurazyme) is the primary treatment option for patients with attenuated mucopolysaccharidosis type I (MPS I). This study examined the effect of early ERT on clinical manifestations. This multinational, retrospective case series abstracted data from records of 20 patients with Hurler-Scheie syndrome within nine sibships that included older siblings treated with laronidase after the development of significant clinical symptoms, and younger siblings treated before significant symptomatology. Median age at diagnosis was 5.6 and 0.5 years for older and younger siblings, respectively. Median age at ERT initiation was 7.9 and 1.9 years for older and younger siblings, respectively. Improvement or stabilization of somatic signs and symptoms was more notable in younger siblings. Organomegaly present at onset of ERT improved in the majority of both older and younger siblings. Analysis of physician-rated symptom severity demonstrated that cardiac, musculoskeletal, and cognitive symptoms, when absent or mild in younger siblings at ERT initiation, generally did not develop or progress. The majority of older siblings had height/length Z-scores greater than two standard deviations below the mean (less than -2) at both time points. In general, Z-scores for younger siblings were closer to the sex- and age-matched means at follow-up. These findings suggest early initiation of laronidase, prior to the onset of symptoms in patients with attenuated MPS I, can slow or prevent the development of severe clinical manifestations.

This school-level longitudinal study examined 7 years of clinical performance data to determine differences (effects) in students and annual changes within a school and between schools; examine how much their predictors (characteristics) influenced the variation in student performance; and calculate estimates of the schools' initial status and growth. A school-level longitudinal model was tested: level 1 (between students), level 2 (annual change within a school), and level 3 (between schools). The study sample comprised students who belonged to the CPX Consortium (n=5,283 for 2005~2008 and n=4,337 for 2009~2011). Despite a difference between evaluation domains, the performance outcomes were related to individual large-effect differences and small-effect school-level differences. Physical examination, clinical courtesy, and patient education were strongly influenced by the school effect, whereas patient-physician interaction was not affected much. Student scores are influenced by the school effect (differences), and the predictors explain the variation in differences, depending on the evaluation domain.

To compare caries status assessment of posterior teeth of young Chinese adults by using clinical examination alone and with the supplemental use of bitewing radiographs. Two calibrated dentists examined the posterior teeth of 200 Chinese university students (aged 18-24 years) using dental mirrors and probes under optimal lighting. Caries was diagnosed by visual detection of carious cavities. Duplicate examinations were performed to monitor intra- and inter-examiner variations. Bitewing radiographs were taken and examined by an independent dentist. Caries was recorded when a lesion extended into dentine. Among the 3,162 posterior teeth examined, 113 were detected with caries. More than one third (35.4%) of the caries found in the posterior teeth was not detected from reading the radiographs but was detected by clinical examination. About half (51.4%) of the caries was found on the bitewing radiographs only, leaving 13.2% being detected by using either method. With the supplement of bitewing radiographs, there was a 105% increase in the number of carious lesions detected. This leads to a correction factor of 1.13 for adjustment of the mean DMFT score obtained from conducting clinical examinations alone. Due to the significant number of clinically undetected carious cavities in these young Chinese adults who live in a community with water fluoridation, it may be advisable to use a correction factor to adjust the caries experience obtained from epidemiological surveys when bitewing radiographs are not available.

The overall risk of malignancy in ovarian neoplasm is 13% in premenopausal women and 45% in postmenopausal women. Differentiating benign and malignant disease with frozen section is possible during operation; however, information on patients' history, physical examination, paraclinical criteria (tumour markers, imaging) and gross examination of tumour can also be helpful in planing the surgery. This study was conducted on 150 women who underwent laparotomy due to adnexal mass between April 2003 and October 2005 at Vali-e-Asr Hospital, Tehran, Iran. Sensitivity and specificity of clinical assessment (history, tumour marker and imaging), gross examination and frozen section were calculated. Based on our findings frozen section had the highest sensitivity for diagnosing malignant tumour comparing with other methods of diagnosis (88.9%). Sensitivity was 71.3% for preoperative clinical examination, 83% for ultrasonography, 89.8% for CT scan, 70% for CA125 and 84.1% for gross examination, likewise the highest specificity was seen for frozen section (93.5%). This data confirm that frozen section diagnosis is a reliable method for the surgical management of patients with an ovarian mass, but history of disease, Para clinical criteria and gross examination can help to surgeon to perform on appropriate operation in the areas where frozen section is not possible.

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.

Medical students learn clinical reasoning, in part, through patient care. Although the numbers of patients seen is associated with knowledge examination scores, studies have not demonstrated an association between patient problems and an assessment of clinical reasoning. To examine the reliability of a clinical reasoning examination and investigate whether there was association between internal medicine core clerkship students' performance on this examination and the number of patients they saw with matching problems during their internal medicine clerkship. Students on the core internal medicine clerkship at the Uniformed Services University students log 11 core patient problems based on the Clerkship Directors in Internal Medicine curriculum. On a final clerkship examination (Multistep), students watch a scripted video encounter between physician and patient actors that assesses three sequential steps in clinical reasoning: Step One focuses on history and physical examination; Step Two, students write a problem list after viewing additional clinical findings; Step Three, students complete a prioritized differential diagnosis and treatment plan. Each Multistep examination has three different cases. For graduating classes 2010-2012 (n = 497), we matched the number of patients seen with the problem most represented by the Multistep cases (epigastric pain, generalized edema, monoarticular arthritis, angina, syncope, pleuritic chest pain). We report two-way Pearson correlations between the number of patients students reported with similar problems and the student's percent score on: Step One, Step Two, Step Three, and Overall Test. Multistep reliability: Step 1, 0.6 to 0.8; Step 2, 0.41 to 0.65; Step 3, 0.53 to 0.78; Overall examination (3 cases): 0.74 to 0.83. For three problems, the number of patients seen had small to modest correlations with the Multistep Examination of Analytic Ability total score (r = 0.27 for pleuritic pain, p < 0.05, n = 81 patients; r = 0

Objective structured clinical examinations (OSCEs) have proven to be a powerful tool. They possess more than a 30-year track record in assessing the competency of medical students, residents, and fellows. Objective structured clinical examinations have been used successfully in a variety of medical specialties, including surgery. They have recently found their way into the subspecialty of plastic surgery. This article uses a systematic review of the available literature on OSCEs and their recent use in plastic surgery. It incorporates survey results assessing program directors' views on the use of OSCEs. Approximately 40% of programs surveyed use OSCEs to assess the Accreditation Council for Graduate Medical Education core competencies. We found that 40% use OSCEs to evaluate specific plastic surgery milestones. Objective structured clinical examinations are usually performed annually. They cost anywhere between $100 and more than $1000 per resident. Four milestones giving residents the most difficulties on OSCEs were congenital anomalies, noncancer breast surgery, breast reconstruction, and practice-based learning and improvement. It was determined that challenges with milestones were due to lack of adequate general knowledge and surgical ward patient care, as well as deficits in professionalism and system-based problems. Programs were able to remediate weakness found by OSCEs using a variety of methods. Objective structured clinical examinations offer a unique tool to objectively assess the proficiency of residents in key areas of the Accreditation Council for Graduate Medical Education core competencies. In addition, they can be used to assess the specific milestones that plastic surgery residents must meet. This allows programs to identify and improve identified areas of weakness.

Association between maternal comorbidity and preterm birth by severity and clinical subtype: retrospective cohort study

PubMed Central

2011-01-01

Background Preterm birth (PTB) is a major cause of infant morbidity and mortality, but the relationship between comorbidity and PTB by clinical subtype and severity of gestational age remains poorly understood. We evaluated associations between maternal comorbidities and PTB by clinical subtype and gestational age. Methods We conducted a retrospective cohort study of 1,329,737 singleton births delivered in hospitals in the province of Québec, Canada, 1989-2006. PTB was classified by clinical subtype (medically indicated, preterm premature rupture of membranes (PPROM), spontaneous preterm labour) and gestational age (< 28, 28-31, 32-36 completed weeks). Odds ratios (OR) of PTB by clinical subtype for systemic and localized maternal comorbidities were estimated using polytomous logistic regression, adjusting for maternal age, grand multiparity, and period. Attributable fractions were calculated. Results PTB rates were higher among mothers with comorbidity (10.9%) compared to those without comorbidity (4.7%). Several comorbidities were associated with greater odds of medically indicated PTB compared with no comorbidity, but only comorbidities localized to the reproductive system were associated with spontaneous PTB. Drug dependence and mental disorders were strongly associated with PPROM and spontaneous PTBs across all gestational ages (OR > 2.0). At the population level, several major comorbidities (placental abruption, chorioamnionitis, oliogohydramnios, structural abnormality, cervical incompetence) were key contributors to all clinical subtypes of PTB, especially at < 32 weeks. Major systemic comorbidities (preeclampsia, anemia) were key contributors to PPROM and medically indicated PTBs. Conclusions The relationship between comorbidity and clinical subtypes of PTB depends on gestational age. Prevention of PPROM and spontaneous PTB may benefit from greater attention to preeclampsia, anemia and comorbidities localized to the reproductive system. PMID:21970736

Background: Healthcare-associated pneumonia (HCAP) is associated with drug-resistant pathogens and high mortality, and there is no clear evidence that this is due to inappropriate antibiotic therapy. This study was to elucidate the clinical features, pathogens, therapy, and outcomes of HCAP, and to clarify the risk factors for drug-resistant pathogens and prognosis. Methods: Retrospective observational study among hospitalized patients with HCAP over 10 years. The primary outcome was 30-day all-cause hospital mortality after admission. Demographics (age, gender, clinical features, and comorbidities), dates of admission, discharge and/or death, hospitalization costs, microbiological results, chest imaging studies, and CURB-65 were analyzed. Antibiotics, admission to Intensive Care Unit (ICU), mechanical ventilation, and pneumonia prognosis were recorded. Patients were dichotomized based on CURB-65 (low- vs. high-risk). Results: Among 612 patients (mean age of 70.7 years), 88.4% had at least one comorbidity. Commonly detected pathogens were Acinetobacter baumannii, Pseudomonas aeruginosa, and coagulase-negative staphylococci. Initial monotherapy with β-lactam antibiotics was the most common initial therapy (50%). Mean age, length of stay, hospitalization expenses, ICU admission, mechanical ventilation use, malignancies, and detection rate for P. aeruginosa, and Staphylococcus aureus were higher in the high-risk group compared with the low-risk group. CURB-65 ≥3, malignancies, and mechanical ventilation were associated with an increased mortality. Logistic regression analysis showed that cerebrovascular diseases and being bedridden were independent risk factors for HCAP. Conclusion: Initial treatment of HCAP with broad-spectrum antibiotics could be an appropriate approach. CURB-65 ≥3, malignancies, and mechanical ventilation may result in an increased mortality.

Current understanding of the clinical features of persons with melorheostosis is restricted primarily to individual case reports and small case series. To assess the clinical features of patients with melorheostosis treated at our institution from 1972 through 2010. Chart review. Tertiary academic medical center. Twenty-three patients with "definite" and one patient with "probable" melorheostosis based on radiographic criteria. The eligible study cohort was identified through the Rochester Medical Index database. Further diagnostic confirmation of patients with melorheostosis was performed by radiographic review. We evaluated age at first visit to our institution, gender, affected body area, number of bones affected, presenting symptoms, surgical evaluation, and therapies provided. The average age at first evaluation at our clinic was 36.5 years (median 41.5 years, range 3-68 years). The female to male ratio was 4:1. The lower extremity was most commonly affected (66.6%), followed by upper extremity (33.3%), spine (16.6%), and head (8.3%). One-third of patients had involvement of a single bone; two-thirds had multiple bone involvement. Pain was the most common presenting concern (83.3%), followed by deformity (54.1%), limitation of movement (45.8%), numbness (37.5%), and weakness (25.0%). Most patients had a physician evaluation (87.5%); patients also underwent orthopedic surgery (45.8%), physical therapy (33.3%), and occupational therapy (12.5%). Melorheostosis is a rare sclerotic bone disease resulting in pain, deformity, and dysfunction. An interdisciplinary approach to care should include nonoperative and operative evaluation, as well as appropriate therapies. A prospective approach to evaluation, including imaging and physical examinations, would provide valuable longitudinal data. IV.

A high prevalence of cholestatic disease, including gallbladder mucocele (GBM), has been reported in dogs with naturally occurring pituitary-dependent hyperadrenocorticism (PDH). Differences exist in the clinical features of dogs with PDH and concurrent cholestatic disease, and also is the management of these dogs with trilostane. Sixty-five client-owned dogs with naturally occurring PDH. This was a retrospective, observational case series. Each dog was treated with trilostane for at least 3 months before the study, and had a good clinical response, as determined by owners. Statistical comparisons of clinical signs, results of routine blood tests, basal and post-ACTH cortisol concentration, and optimal trilostane dosage were made after dogs were separated into the following 3 groups by ultrasonographic imaging: normal on ultrasound (NOU) group, cholestasis group, and GBM group. The GBM group had more severe clinical signs and significantly different total serum cholesterol concentration and post-ACTH stimulation cortisol concentration at the time of diagnosis. Dogs that weighed <6 kg had a significantly higher prevalence of cholestatic disease than did the other dogs (P = .003). The optimal trilostane dosages for the GBM and cholestasis groups were 2.5 and 1.5 times the dosage of the NOU group, respectively (P < .001). Gallbladder disease associated with cholestatic disease is correlated with PDH in dogs, in both its clinical features and drug management. These findings may be associated with hypercholesterolemia, unidentified genetic factors, and the hydrophobic nature of trilostane. Copyright © 2017 The Authors.

Sacroiliac joint syndrome (SIJ) is diagnosed in 10% to 25% of cases of lower back pain. The response to traditional radiofrequency (RF) denervation of the SIJ has being inconsistent. The Simplicity III RF probe (Neruotherm. Inc.) offers a novel treatment option. To evaluate the long-term clinical outcome (12 months) refractory SIJ syndrome in terms of pain intensity and functional improvement. A 50% reduction in intensity pain intensity (VAS) at 12 months was deemed clinically significant. A 12-month retrospective observational evaluation all of adults treated with RF for refractory SIJ. Chronic pain management center. The medical records of all adults treated with this technique was retrospectively reviewed. The primary outcome was pain intensity scores (VAS) over a 12 months period; Secondary outcomes included Roland-Morris Functional scores (RMF), Brief Pain Inventory (BPI), general health assessment (Sf12), and patient satisfaction scores (GPI), which were recorded pre and post denervation. Pain Intensity improved by 4.7 points compared to pre-treatment representing a 61% reduction in pain at 12 months (n=11, P < 0.001). Significant improvements in (a) RMF (P < 0.01, W2 = 0.63 (large effect size); (b) BPI (P < 0.001, W2 = 0.72 (strong effect size); and (c) Sf12 (P < 0.01) were noted. Overall patients were satisfied with the outcome (GPI = 77.7%). The retrospective in nature of the study and the small sample size are limitations. As it was our policy to monitor the progress of the individuals since the introduction of this technique a reliable method of recording the baseline and outcome variables at each point of contact was in place. Access to a complete set of variables in all individuals over a 12-month period was therefore possible, which we feel contributes to the quality of the dataset. By creating a consistent radiofrequency lesion between the sacral foramen and the SIJ will reliably capture the innervation to the SIJ with significant long-term clinical

Systemic amyloidosis is a rare but life-threatening complication of inflammatory bowel disease (IBD), most cases being reported among Crohn's disease (CD) patients. The only two available retrospective studies showed a prevalence ranging from 0.9% to 3% among CD patients. To evaluate the prevalence of secondary systemic amyloidosis in a large IBD cohort of a referral centre, and to describe its clinical characteristics and outcome. Patients diagnosed with amyloidosis were identified among 1006 IBD patients included in the IBD database of our centre, and their medical records were carefully reviewed. Among a total of 1006 IBD patients, 5 cases of amyloidosis were identified, all of them with CD, resulting in a prevalence of 0.5% for IBD and 1% for CD. Two patients died after developing renal failure. Two patients were treated with anti-TNF agents, showing a clinical improvement of their amyloidosis. Secondary amyloidosis occurs mainly in long-lasting, complicated, Crohn's disease and seems to be as prevalent among IBD patients as previously reported.

SUBJECTS AND MATERIAL: All medical students of October 2004 admission who took part in the October 2010 National Comprehensive Pre-internship Examination (NCPE) and pre-internship OSCE were included in the study (n = 130). OSCE and NCPE scores and medical grade point average (GPA) were collected. GPA was highly correlated with NCPE (r = 0.76 and P<0.001) and moderately with OSCE (r = 0.68 and P < 0.001). Similarly a moderate correlation was observed between NCPE and OSCE scores(r = 0.6 and P < 0.001).Linear stepwise regression shows r(2) of a model applying GPA as predictor of OSCE score is 0.46 (β = 0.68 and P < 0.001), while addition of gender to the model increases r(2) to 0.59 (β = 0.61 and 0.36, for GPA and male gender, respectively and P < 0.001). Logistic forward regression models shows male gender and GPA are the only dependent predictors of high score in OSCE. OR of GPA and male gender for high OSCE score are 4.89 (95% CI = 2.37-10.06) and 6.95 (95% CI = 2.00-24.21), respectively (P < 0.001). Our findings indicate OSCE and examination which mainly evaluate knowledge, judged by GPA and NCPE are moderately to highly correlated. Our results illustrate the interwoven nature of knowledge and clinical skills. In other words, certain level of knowledge is crucial for appropriate clinical performance. Our findings suggest neither OSCE nor written forms of assessments can replace each other. They are complimentary and should also be combined by other evaluations to cover all attributes of clinical competence efficiently.

Clinical breast examination (CBE) is traditionally taught to third-year medical students using a lecture and a tabletop breast model. The opportunity to clinically practice CBE depends on patient availability and willingness to be examined by students, especially in culturally sensitive environments. We propose the use of a hybrid simulation model consisting of a standardized patient (SP) wearing a silicone breast simulator jacket and hypothesize that this, compared to traditional teaching methods, would result in improved learning. Consenting third-year medical students (N = 82) at a university-affiliated tertiary care center were cluster-randomized into two groups: hybrid simulation (breast jacket + SP) and control (tabletop breast model). Students received the standard lecture by instructors blinded to the randomization, followed by randomization group-based learning and practice sessions. Two weeks later, participants were assessed in an Objective Structured Clinical Examination (OSCE), which included three stations with SPs blinded to the intervention. The SPs graded the students on CBE completeness, and students completed a self-assessment of their performance and confidence during the examination. CBE completeness scores did not differ between the two groups (p = 0.889). Hybrid simulation improved lesion identification grades (p < 0.001) without increasing false positives. Hybrid simulation relieved the fear of missing a lesion on CBE (p = 0.043) and increased satisfaction with the teaching method among students (p = 0.002). As a novel educational tool, hybrid simulation improves the sensitivity of CBE performed by medical students without affecting its specificity. Hybrid simulation may play a role in increasing the confidence of medical students during CBE.

The first objective of this study was to retrospectively evaluate zirconia-based restorations (ZBR). The second was to correlate failures with clinical parameters and to identify and to analyse chipping failures using fractographic analysis. 147 ZBR (tooth- and implant-supported crowns and fixed partial dentures (FPDs)) were evaluated after a mean observation period of 41.5 ± 31.8 months. Accessorily, zirconia implant abutments (n=46) were also observed. The technical (USPHS criteria) and the biological outcomes of the ZBR were evaluated. Occlusal risk factors were examined: occlusal relationships, parafunctional habits, and the presence of occlusal nightguard. SEM fractographic analysis was performed using the intra-oral replica technique. The survival rate of crowns and FPDs was 93.2%, the success rate was 81.63% and the 9-year Kaplan-Meier estimated success rate was 52.66%. The chipping rate was 15% and the framework fracture rate was 2.7%. Most fractographic analyses revealed that veneer fractures originated from occlusal surface roughness. Several parameters were shown to significantly influence veneer fracture: the absence of occlusal nightguard (p=0.0048), the presence of a ceramic restoration as an antagonist (p=0.013), the presence of parafunctional activity (p=0.018), and the presence of implants as support (p=0.026). The implant abutments success rate was 100%. The results of the present study confirm that chipping is the first cause of ZBR failure. They also underline the importance of clinical parameters in regards to the explanation of this complex problem. This issue should be considered in future prospective clinical studies. Practitioners can reduce chipping failures by taking into account several risk parameters, such as the presence of a ceramic restoration as an antagonist, the presence of parafunctional activity and the presence of implants as support. The use of an occlusal nightguard can also decrease failure rate. Copyright © 2013 Elsevier

Constipation is a common clinical problem with insufficient attention. Medication-emergent constipation is a rarely studied adverse reaction in patients with obsessive-compulsive disorder (OCD). In this descriptive study, we retrospectively investigated the prevalence of laxative use and its relationship with clinical characteristics in hospitalized OCD patients. A total of 51 OCD patients were included in the final analysis. The proportion of patients using laxatives was 31.4%, and the commonly used laxatives were phenolphthalein tablet, lactulose and congrongtongbian oral liquid (a patent herbal medicine). In the laxative group, hospital stays were longer when compared to the nonlaxative group. Moreover, the dose of paroxetine was higher in patients treated with laxatives than in those without laxative use. Correlation analysis indicated that laxative use was positively associated with hospital stays, as well as the dose of paroxetine. The current study provided a preliminary picture of constipation and laxative use in hospitalized OCD patients. Close monitoring and treatment of constipation are recommended in OCD patients with pharmacotherapy.

Despite the large number of tuberculosis (TB) patients treated in South Africa (SA), there are few descriptions in the published literature of drug-susceptible TB patient characteristics, mode of diagnosis or treatment outcomes in routine public sector treatment programmes. To enhance the evidence base for public sector TB treatment service delivery, we reported the characteristics of and outcomes for a retrospective cohort of adult TB patients at public sector clinics in the Johannesburg Metropolitan Municipality (JHB), SA. We collected medical record data for a retrospective cohort of adult (≥18 years) TB patients registered between 1 April 2011 and 31 March 2012 at three public sector clinics in JHB. Data were abstracted from National TB Programme clinic cards and the TB case registers routinely maintained at study sites. We report patient characteristics, mode of diagnosis, mode of treatment supervision, treatment characteristics, HIV status and treatment outcomes for this cohort. A total of 544 patients were enrolled in the cohort. Most (86%) were new TB cases, 81% had pulmonary TB, 58% were smear-positive at treatment initiation and 71% were HIV co-infected. Among 495 patients with treatment outcomes reported, 80% (n=394) had successful outcomes, 11% (n=55) were lost to follow-up, 8% (n=40) died and 1% (n=6) failed treatment. Primary healthcare clinics in JHB are achieving relatively high rates of success in treating drug-susceptible TB. Missing laboratory results were common, including follow-up smears, cultures and drug susceptibility tests, making it difficult to assess adherence to guidelines and leaving scope for substantial improvements in record-keeping at the clinics involved.

To evaluate the tolerability and clinical effects of subcutaneous (SC) levetiracetam for the treatment of epileptic seizures in a palliative care setting, we conducted a retrospective chart review of patients treated with subcutaneous levetiracetam in the Department of Palliative Medicine at the University Munich, between September 2006 and March 2013. The following parameters were extracted from the charts: reason for antiepileptic drug treatment, daily dose, concentration, infusion rate, co-administration of other drugs, and clinical effects. Furthermore, the charts were screened for signs of adverse drug reactions, e.g., irritation or pain at the infusion site. We identified 20 patients that were treated with levetiracetam SC in the inpatient (n = 7) and outpatient (n = 13) settings. Most patients (n = 17) tolerated the subcutaneous infusion well. Nineteen patients (95%) received levetiracetam in combination with other drugs. These were mainly metamizol (80%), midazolam (75%), and morphine (45%). The median dose of levetiracetam was 95.8 mg/h (SD 37 mg/h), median osmolarity of the infusion solution 2203 mOsmol/L (SD 717 mOsmol/L), and infusion rate 2 mL/h (SD 2.4 ml/h). In 16 patients (80%), seizures were controlled and status epilepticus were interrupted, respectively. We conclude that SC levetiracetam is an effective treatment and well tolerated in the palliative care setting.

Ceramic veneer fracture is a frequent complication in implant-borne fixed restorations. The retrospective clinical study assesses the effect of bruxism on this complication. A sample of 507 implant-borne fixed units inserted between 1995 and 2011 in 144 patients were examined. Any detected veneer fractures were assigned to one of four groups according to extent and position. A hypothetical correlation between bruxism and ceramic veneer fractures was examined. Of 34 patients (23.6%) with at least one ceramic veneer fracture, 24 were bruxers (70%) and 10 were nonbruxers (30%) (P = .002). Bruxism may pose a risk for ceramic fractures.

To improve the diagnostic rate of gastric lymphoma by analyzing clinical and endoscopic features of patients with gastric lymphoma and suspected gastric lymphoma. Clinical and endoscopic records of 35 patients with gastric lymphoma (positive group) and 133 patients with suspected gastric lymphoma but subsequent non-malignant pathology (negative group) were analyzed retrospectively. Data from another 99 gastric lymphoma patients with malignant pathology but nonspecific endoscopy (endoscopy non-suspect group) were analyzed. Abdominal pain was the predominant symptom reported in both the positive and negative lymphoma groups, representing 60.0 and 52.5%, respectively. No significant differences in age, sex and clinical manifestations in subjects from the two groups were found. In the positive group, 54.3% were ulcerative; 34.3%, infiltrative; 8.5%, polypoid; and 2.9%, granulonodular. In the negative group, 52.6% were infiltrative; 42.1%, ulcerative; 4.5%, granulonodular; and 0.75%, polypoid. The endoscopic results varied between the two groups (p < 0.05). In the non-suspect group, 66.7% were ulcerative; 17.2%, infiltrative; 14.1%, polypoid; and 2.0%, granulonodular. With regards to histology, diffuse large B cell lymphoma was the most common subtype. The sensitivity of endoscopy was 60% for detecting malignancy and 21% for gastric lymphoma. The present study suggests that gastric lymphoma and suspected gastric lymphoma have similar clinical features. Gastric lymphoma presented mainly as macroscopic ulcerative lesions, whereas suspected gastric lymphoma appeared mainly as infiltrative lesions. Although the diagnostic rate of gastric lymphoma was relatively low (21%), it can be identified by endoscopy (60%). To improve diagnosis, repetitive endoscopic biopsies should be performed and novel endoscopic techniques developed in the future.

Investigating possible ethnicity and sex bias in clinical examiners: an analysis of data from the MRCP(UK) PACES and nPACES examinations.

Bias of clinical examiners against some types of candidate, based on characteristics such as sex or ethnicity, would represent a threat to the validity of an examination, since sex or ethnicity are 'construct-irrelevant' characteristics. In this paper we report a novel method for assessing sex and ethnic bias in over 2000 examiners who had taken part in the PACES and nPACES (new PACES) examinations of the MRCP(UK). PACES and nPACES are clinical skills examinations that have two examiners at each station who mark candidates independently. Differences between examiners cannot be due to differences in performance of a candidate because that is the same for the two examiners, and hence may result from bias or unreliability on the part of the examiners. By comparing each examiner against a 'basket' of all of their co-examiners, it is possible to identify examiners whose behaviour is anomalous. The method assessed hawkishness-doveishness, sex bias, ethnic bias and, as a control condition to assess the statistical method, 'even-number bias' (i.e. treating candidates with odd and even exam numbers differently). Significance levels were Bonferroni corrected because of the large number of examiners being considered. The results of 26 diets of PACES and six diets of nPACES were examined statistically to assess the extent of hawkishness, as well as sex bias and ethnicity bias in individual examiners. The control (odd-number) condition suggested that about 5% of examiners were significant at an (uncorrected) 5% level, and that the method therefore worked as expected. As in a previous study (BMC Medical Education, 2006, 6:42), some examiners were hawkish or doveish relative to their peers. No examiners showed significant sex bias, and only a single examiner showed evidence consistent with ethnic bias. A re-analysis of the data considering only one examiner per station, as would be the case for many clinical examinations, showed that analysis with a single examiner runs a serious

To determine perceptions of final year students about observed structured clinical examination (OSCE) and to determine its acceptance among these students. Sequential mixed method design using survey questionnair and in-depth interviews. The study constituted a one-time survey and in-depth interviews conducted over a period of three consecutive days during final year MBBS annual examination at OSCE centre, from April 04, 2010 to April 06, 2010. Three hundred and fifty final year MBBS students, selected through non-probability convenience sampling, were asked to fill the 12-item questionnaire. Three hundred and thirty one students returned the forms. In-depth, structured interviews with 22 students, selected by non-probability purposive sampling, were conducted. The interviews were tape recorded for subsequent transcription. The statistical analysis was done using SPSS 17. The qualitative data was analyzed through content analysis techniques. Three hundred and thirty one final year MBBS students (50.6% females) filled the questionnaire (response rate 94.6%). Fifty three percent respondents agreed that the OSCE tasks were taught during clinical rotations. The experience was stressful for 67.9% respondents. Inadequate prior guidelines, inadequate time for stations, newness of the assessment format and vague instructions were the main causes for stress. Over 70% of the students felt that OSCE helped them identify areas of weakness in their practical and clinical skills; 56.5% felt that the stations dealt with practical skills. Seventy nine percent students were happy with the attitude of the examiners while 19% students felt that the facilitators were uncooperative; failure of the examiners to observe the students during performance of the tasks was the major cause for dissatisfaction. Nearly thirty percent (29.9%) respondent felt that the stations were difficult to understand. Over forty nine percent (49.7%) complained that adequate guidelines were not given prior to

To investigate the association between pernicious anemia and other autoimmune diseases. This retrospective and bicentric study was conducted at Reims and Strasbourg University Hospitals and involved 188 patients with pernicious anemia examined between 2000 and 2010 in order to search for other autoimmune diseases and to evaluate the role of pernicious anemia in autoimmune polyglandular syndrome. A total of 74 patients with a combination of pernicious anemia and other autoimmune diseases were included in the study. Our study revealed the privileged association of pernicious anemia with autoimmune thyroiditis. The association of pernicious anemia and autoimmune thyroiditis are a part of the autoimmune polyglandular syndrome type 3b. We suggest undertaking a systematic clinical examination and laboratory investigations in search of autoimmune thyroiditis in patient(s) with the diagnosis of pernicious anemia. The association of pernicious anemia and autoimmune thyroiditis is frequent and a part of autoimmune polyglandular 3b.

The visualization of the subthalamic nucleus (STN) on magnetic resonance imaging (MRI) is variable. Studies of the contribution of patient-related factors and intrinsic brain volumetrics to STN visualization have not been reported previously. To assess the visualization of the STN during deep brain stimulation (DBS) surgery in a clinical setting. Eighty-two patients undergoing pre-operative MRI to plan for STN DBS for Parkinson disease were retrospectively studied. The visualization of the STN and its borders was assessed and scored by 3 independent observers using a 4-point ordinal scale (from 0 = not seen to 3 = excellent visualization). This measure was then correlated with the patients' clinical information and brain volumes. The mean STN visualization scores were 1.68 and 1.63 for the right and left STN, respectively, with a good interobserver reliability (intraclass correlation coefficient: 0.744). Older age and decreased white matter volume were negatively correlated with STN visualization (p < 0.05). STN visualization is only fair to good on routine MRI with good concordance of interindividual rating. Advancing age and decreased white matter are associated with poor visualization of the STN. Knowledge about factors contributing to poor visualization of the STN could alert a surgeon to modify the imaging strategy to optimize surgical targeting. © 2018 S. Karger AG, Basel.

Syphilitic chorioretinitis should be included in differential diagnosis of any form of ocular inflammation. A significantly higher proportion of human immunodeficiency virus (HIV)-positive patients with ocular syphilis as compared to HIV-negative cases have been reported in published studies. However, the clinical signs and symptoms are more insidious in HIV-negative patients who are easily misdiagnosed. We report a series of cases of ocular syphilis and describe the clinical manifestations and treatment outcomes of syphilitic chorioretinitis in HIV-negative patients in China.This was a retrospective case series study. The clinical records of patients with syphilis chorioretinitis were reviewed. Demographic information and findings of fundus fluorescein angiography (FFA), indocyanine green angiography (ICGA), and spectral domain optical coherence tomography (SD-OCT) were analyzed. All patients received the standard treatment. Ophthalmology examination and laboratory evaluation were repeated every 3 months. All changes were recorded. The treatment was considered successful if the patients had no inflammation in both eyes and rapid plasma reagin titer was negative after therapy.The study examined 41 eyes of 28 HIV-negative patients. The main complaints were blurry vision, floaters, and visual field defect. Twenty-seven eyes presented with panuveitis, and all had posterior involvement, including uveitis, vasculitis, chorioretinitis, and optic neuritis. The most common manifestations were uveitis and retinal vasculitis. Disc hyperfluorescence and persistent dark spots were the most common findings on FFA and ICGA. The ill-defined inner segment/outer segment junction was the most frequent manifestation on SD-OCT. Patients were diagnosed with syphilitic uveitis based on positive serological tests. Best-corrected visual acuity (BCVA) was improved in 34 eyes after treatment. Eleven patients were misdiagnosed before serological tests were performed. The delay in treatment

Prevalence of clinical findings at examinations of young Swedish warmblood riding horses

2013-01-01

Background Soundness of an individual horse is important for animal welfare and owner economy. However, knowledge of health status in normal horse populations is limited due to lack of systematic health recordings. The aim of the investigation was to study the prevalence of veterinary clinical findings in 4-5-year-old Swedish warmblood riding horses, and their influence on overall health scores, where associations to future longevity has been indicated. Results The prevalence of clinical findings in 8,281 horses examined during 1983–2005 was studied according to a standardised protocol and related to overall health scores in linear statistical models. Effects of sex, age, examination event and changes over time were included. In total, 49% of the horses had clinical findings of medical health (MED), 42% in hooves (HOOF) and 74% of palpatory orthopaedic health (PALP). However, only 6%, 3% and 24% had moderate or severe findings, of MED, HOOF and PALP, respectively. Flexion test reactions were reported in 21% of the horses (5% moderate/severe), heavily influencing the overall score (H2). One fifth of these horses also had findings of unprovoked lameness while 83% had PALP findings (44% with moderate/severe findings). Acute clinical signs, i.e. heat or soreness, had a large influence on the H2 score but were rare, whereas more common clinical findings had smaller effects on overall health. Large variations in recorded health results were observed among events. A decrease in findings has occurred since 1983, in particular for PALP findings. Conclusions Results of occurrence and relevance of evaluated clinical findings could be used for advice on preventive actions to keep horses sound, and possibly for benchmarking, and genetic evaluation of health traits. The distinct effect of event on recorded clinical findings emphasises that further harmonisation of veterinary examinations are desirable. PMID:23597257

Research has demonstrated some progress in using a clinical examination to predict discogenic or sacroiliac (SI) joint sources of pain. No clear predictors of symptomatic lumbar zygapophysial joints have yet been demonstrated. To identify significant components of a clinical examination that are associated with symptomatic lumbar discs, zygapophysial joints and SI joints. A prospective, criterion-related concurrent validity study performed at a private radiology practice specializing in spinal diagnostics. The sample consisted of 81 patients with chronic lumbopelvic pain referred for diagnostic injections. Contingency tables were constructed for nine features of the clinical evaluation compared with the results of diagnostic injections. Statistical analysis included chi-squared test for independence, phi and odds ratios with confidence intervals. Patients received blinded clinical examinations by physical therapists, and diagnostic injections were used as the criterion standard. Significant relationships were found between discogenic pain and centralization of pain during repeated movement testing, and pain when rising from sitting. Lumbar zygapophysial joint pain was associated with absence of pain when rising from sitting. Sacroiliac joint pain was related to three or more positive pain provocation tests, pain when rising from sitting, unilateral pain and absence of lumbar pain. Significant correlations exist between clinical examination findings and symptomatic lumbar discs, zygapophysial and SI joints. The strongest relationships were seen between SI joint pain and three or more positive pain provocation tests, centralization of pain for symptomatic discs and absence of pain when rising from sitting for symptomatic lumbar zygapophysial joints.

We have retrospectively examined the nature of acute mastioditis (in western Norway) during a 20 year period (1980-2000). Sixty-one cases of AM were identified in 57 patients with a mean age of 3.6 years. We found no significant change in the incidence of AM during the last 20 years. Seven patients were treated solely with intravenous antibiotics and myringotomies. Fifty patients also underwent cortical mastoidectomy, four cases with bilateral surgery. Antibiotic treatment was given to 31 of the patients before admission to hospital and this group had a significant longer duration of symptoms (12.4 days) compared to untreated patients (7.3 days). Streptococcus pneumoniae was the most common organism recovered from patient cultures. Surgery was found to correlate to patients with retroauricular fluctuation or to children with at least two of the three clinical signs: protrusion of the ear, retroauricular oedema and swelling of the ear canal. Our data show that clinical examination only reveal 50% of the cases with surgically proven retroauricular subperiostal abscess. We therefore recommend a CT scan of patients treated conservatively.

The clinical records of 23 dogs (1990-1999) with histopathologically confirmed bacterial meningoencephalomyelitis were evaluated retrospectively. No breed, age, sex, or weight predisposition was found. All the dogs presented with clinical signs of a brain lesion, whereas 5 of 23 had neck pain. Pyrexia was detected in 11 of 23 dogs on admission. CBCs revealed neutrophilic leucocytosis in 7 of 21 dogs and thrombocytopenia in 3 of 21 dogs. The serum chemistry profiles were abnormal in 15 of 21 dogs. The results of cerebrospinal fluid (CSF) analysis were abnormal in 13 of 14 dogs and aerobic CSF culture was positive for bacteria in 1of 8 samples. At postmortem examination, the lesions were localized to the central nervous system. Escherichia coli, Streptococcus, and Klebsiella spp were the most frequently isolated bacteria from cultures collected at postmortem examination. Twelve papers reporting 51 total clinical cases of canine bacterial meningoencephalomyelitis were reviewed. The clinical signs and results of the CBC, serum chemistry, blood culture, and CSF analysis were collated and compared with those of this study. The results of the CSF analysis in this study were similar to those in the literature. CSF cultures documented in the literature were positive for Staphylococcus, Pasteurella. Actinomyces, Nocardia spp, and various anaerobic species including Peptostreptococcus, Eubacterium, and Bacteroides spp.

Because of the increase in healthcare-associated infections, appearance of highly resistant bacteria, and that of emerging/re-emerging infectious diseases, it is necessary for the skills of clinical microbiological technologists and the associated technology to be improved. Technologist in Microbiology (4,717 certified) and Specialist in Microbiology (58 certified) are authorized qualifications in the field of examination for clinical microbiology, with a history of 60 years, and Clinical Microbiological Technologist (670 certified) and Infection Control Microbiological Technologist (ICMT) (528 certified) are necessary qualifications to become a member of an infection control team. As problems to be resolved, clarifying the relationships among the authorized qualifications, reconsidering the fairness of evaluating written examinations, and further consideration of the administration method for an increasing number of examinees need to be tackled.

Clinical Performance and Admission Variables as Predictors of Passage of the National Physical Therapy Examination.

Prior studies have explored variables that had predictive relationships with National Physical Therapy Examination (NPTE) score or NPTE failure. The purpose of this study was to explore whether certain variables were predictive of test-takers' first-time score on the NPTE. The population consisted of 134 students who graduated from the university's Professional DPT Program in 2012 to 2014. This quantitative study used a retrospective design. Two separate data analyses were conducted. First, hierarchical linear multiple regression (HMR) analysis was performed to determine which variables were predictive of first-time NPTE score. Second, a correlation analysis was performed on all 18 Physical Therapy Clinical Performance Instrument (PT CPI) 2006 category scores obtained during the first long-term clinical rotation, overall PT CPI 2006 score, and NPTE passage. With all variables entered, the HMR model predicted 39% of the variance seen in NPTE scores. The HMR results showed that physical therapy program first-year GPA (1PTGPA) was the strongest predictor and explained 24% of the variance in NPTE scores (b=0.572, p<0.001). The correlational analysis found no statistically significant correlation between the 18 PT CPI 2006 category scores, overall PT CPI 2006 score, and NPTE passage. As 1PTGPA had the most significant contribution to prediction of NPTE scores, programs need to monitor first-year students who display academic difficulty.

Both tools measure many of the same professional requirements but use different modes of assessment, and they may be considered complementary tools to gain a full picture of both the student's ability and skills.

Background The study was performed to determine the epidemiological, clinical, and histopathological characteristics and prognosis of primary mucosal melanoma of the head and neck (MMHN) in Denmark. Material and methods This was a national retrospective multicenter study of patients diagnosed with MMHN between 1982 and 2012 in Denmark. Data were retrieved from national databases and patient records. Incidence trends were examined for the entire period. We prepared survival curves and performed univariate and multivariate analysis for the period 1992-2012 to identify possible prognostic factors. Results No significant trends in incidence were found in the study period. The three-year overall and disease-free survival rates for MMHN were 46.5% and 35.5%, respectively. Negative margins was an independent predictor of disease-free survival, and age below 65, absence of distant metastases, and low overall TNM stage were predictors of overall survival. Radiotherapy did not improve survival significantly. Recurrence rates were high, even for patients with negative margins. Conclusions MMHN remains a rare disease with a poor prognosis, particularly for patients aged over 65, those with distant metastasis, and those with advanced TNM stage. Importantly, the rate of recurrence is lowest in patients with negative margins.

Ectodermal dysplasias form a complex, nosologic group of diseases with defects in at least 2 ectodermal structures. A retrospective study of patients with ectodermal dysplasia seen at our department over a period of 19 years (1994-2013) was performed. The study population consisted of 67 patients covering 17 different diagnoses. Forty-five families were identified of which 26 were sporadic cases with no affected family members. In 27 tested families a disease-causing mutation was identified in 23 families. Eleven mutations were novel mutations. To our knowledge, we present the first large ectodermal dysplasia cohort focusing on clinical manifestations in combination with mutational analysis. We recommend a nationwide study to estimate the prevalence of the ectodermal dysplasia and to ensure relevant molecular genetic testing which may form the basis of a national ectodermal dysplasia database.

Legionnaires' disease (LD) is associated with high mortality rates and poses a diagnostic and therapeutic challenge. Use of the rapid urinary antigen test (UAT) has been linked to improved outcome. We examined the association between the method of diagnosis (UAT or culture) and various clinical and microbiological characteristics and outcome of LD. Consecutive patients with pneumonia and confirmation of Legionella infection by a positive UAT and/or a positive culture admitted between the years 2006-2012 to a university hospital were retrospectively studied. Isolated L. pneumophila strains were subject to serogrouping, immunological subtyping and sequence-based typing. Variables associated with 30-day all-cause mortality were analyzed using logistic regression as well as cox regression. Seventy-two patients were eligible for mortality analyses (LD study group), of whom 15.5 % have died. Diagnosis based on positive L. pneumophila UAT as compared to positive culture (OR = 0.18, 95 % CI 0.03-0.98, p = 0.05) and administration of appropriate antibiotic therapy within 2 hospitalization days as compared to delayed therapy (OR = 0.16, 95 % CI 0.03-0.90, p = 0.04) were independently associated with reduced mortality. When controlling for intensive care unit (ICU) admissions, the method of diagnosis became non-significant. Survival analyses showed a significantly increased death risk for patients admitted to ICU compared to others (HR 12.90, 95 % CI 2.78-59.86, p = 0.001) and reduced risk for patients receiving appropriate antibiotic therapy within the first two admissions days compared to delayed therapy (HR 0.13, 95 % CI 0.04-0.05, p = 0.001). Legionella cultures were positive in 35 patients (including 29 patients from the LD study group), of whom 65.7 % were intubated and 37.1 % have died. Sequence type (ST) ST1 accounted for 50.0 % of the typed cases and ST1, OLDA/Oxford was the leading phenon (53.8 %). Mortality rate among patients in the LD study group infected with ST

Objective: Journal impact factor (JIF) is often used as a measure of journal quality. A retrospective cohort study determined the ability of clinical article and journal characteristics, including appraisal measures collected at the time of publication, to predict subsequent JIFs. Methods: Clinical research articles that passed methods quality criteria were included. Each article was rated for relevance and newsworthiness by 3 to 24 physicians from a panel of more than 4,000 practicing clinicians. The 1,267 articles (from 103 journals) were divided 60∶40 into derivation (760 articles) and validation sets (507 articles), representing 99 and 88 journals, respectively. A multiple regression model was produced determining the association of 10 journal and article measures with the 2007 JIF. Results: Four of the 10 measures were significant in the regression model: number of authors, number of databases indexing the journal, proportion of articles passing methods criteria, and mean clinical newsworthiness scores. With the number of disciplines rating the article, the 5 variables accounted for 61% of the variation in JIF (R2 = 0.607, 95% CI 0.444 to 0.706, P<0.001). Conclusion: For the clinical literature, measures of scientific quality and clinical newsworthiness available at the time of publication can predict JIFs with 60% accuracy. PMID:22272156

Nursing student medication errors: a retrospective review.

Harding, Lorill; Petrick, Teresa

2008-01-01

This article presents the findings of a retrospective review of medication errors made and reported by nursing students in a 4-year baccalaureate program. Data were examined in relation to the semester of the program, kind of error according to the rights of medication administration, and contributing factors. Three categories of contributing factors were identified: rights violations, system factors, and knowledge and understanding. It became apparent that system factors, or the context in which medication administration takes place, are not fully considered when students are taught about medication administration. Teaching strategies need to account for the dynamic complexity of this process and incorporate experiential knowledge. This review raised several important questions about how this information guides our practice as educators in the clinical and classroom settings and how we can work collaboratively with practice partners to influence change and increase patient safety.

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.

The aim of this study was to evaluate the implementation of the 9th edition of the American College of Chest Physicians (ACCP9) guidelines for prevention of venous thromboembolism in nonsurgical patients in clinical practice in one university and one general Croatian hospital. A retrospective study was conducted at Zadar General Hospital from Zadar and Dubrava University Hospital from Zagreb. Medical charts of all patients admitted to Medical Departments in two periods, before and after implementation of the ACCP9 guidelines, were analyzed. The ACCP9 guidelines were made available to all physicians through the hospital electronic information system immediately after the publication. The Hospital Drug Committees promoted implementation of the guidelines during their periodical clinical visits. Overall, 850 patients were included in the study in two periods. There was no statistically significant difference in the number of high-risk patients receiving thromboprophylaxis after the guidelines implementation in either hospital. In both periods, a signifi-cantly higher number of high-risk patients received thromboprophylaxis in Dubrava University Hos-pital in comparison with Zadar General Hospital (31.7% vs. 3.8% and 40.3% vs. 7.3%, respectively; p<0.001). This study revealed insufficient implementation of evidence-based thromboprophylaxis guidelines in clinical practice in two Croatian hospitals.

Viewpoint: suggestions for a shift in teaching clinical skills to medical students: the reflective clinical examination.

How medical students are taught physical examination (PE) skills appears to have changed little since the 1950s. Textbooks are organized according to organ systems and describe methods of eliciting and recording history and PE data using a routine format. In many medical schools, the preclinical teaching programs for clinical examination skills similarly emphasize an orderly collection of data. Teaching students to use diagnostic reasoning is postponed until students have learned history-taking and PE skills. The authors propose three modifications to this educational approach. First, rather than performing the clinical examination using a routine format, students should be encouraged to form diagnostic hypotheses early on while listening to the patient's narrative, and conduct the subsequent search for history and PE data in a reflective way in order to confirm or refute these hypotheses. Second, the authors propose that interviewing patients and conducting the PE be taught by one-on-one tutoring until students achieve mastery. Last, they suggest that the PE be guided not only by students' diagnostic hypotheses, but also by patients' expectations. These modifications are consistent with current trends in medical education that encourage a reflective practice and problem-based learning (PBL), and they also introduce medical students to the precepts of clinical reasoning. The authors suggest that challenging students to seek specific physical findings may increase the likelihood of detecting findings when they are present, and may transform patient interviewing and conducting the PE from routine activities into intellectually exciting experiences.

To observe the influence of these complexes on potassium levels in a clinical setting, we investigated the influence of herbal complexes containing licorice on potassium levels. We retrospectively examined the medical records of patients treated with herbal complexes containing licorice from January 1, 2010, to December 31, 2010. We recorded the changes in the levels of potassium, creatinine, and blood urea nitrogen and examined the differences between before and after herbal complexes intake using a paired t-test. In addition, we investigated the prevalence of hypokalemia among these patients and reviewed such patients. We identified 360 patients who did not show significant changes in the levels of potassium and creatinine (P = 0.815, 0.289). We observed hypokalemia in 6 patients. However, in 5 patients, the hypokalemia did not appear to be related to the licorice. Thus, we could suggest that herbal complexes containing licorice do not significantly influence the potassium levels in routine clinical herbal therapies. However, we propose that follow-up examination for potassium levels is required to prevent any unpredictable side effects of administration of licorice in routine herbal medicine care. PMID:25045393

Human factors are important causes of error, but little is known about their possible effect during objective structured clinical examinations (OSCE). We have previously identified stress and pressure in OSCE examiners in the postgraduate intercollegiate Membership of the Royal College of Surgeons (MRCS) examination. After modifying examination delivery by changing OSCE stations at lunchtime with no demonstrable effect on candidate outcome, we resurveyed examiners to ascertain whether examiner experience was improved. Examiners (n = 180) from all 4 surgical colleges in the United Kingdom and Ireland were invited to complete the previously validated human factors questionnaire used in 2014. Aggregated scores for each of 4 previously identified factors were compared with the previous data. Unit-weighted z-scores and nonparametric Kruskal-Wallis methods were used to test the hypothesis that there was no difference among the median factor z-scores for each college. Individual Mann-Whitney-Wilcoxon tests (with appropriate Bonferonni corrections) were used to determine any differences between factors and the respective colleges. 141 Completed questionnaires were evaluated (78% response rate) and compared with 108 responses (90%) from the original study. Analysis was based on 26 items common to both studies. In 2014, the college with the highest candidate numbers (England) was significantly different in 1 factor (stress and pressure), compared with Edinburgh (Mann-Whitney-Wilcoxon: W = 1524, p < 0.001) and Glasgow colleges (Mann-Whitney-Wilcoxon: W = 104, p = 0.004). No differences were found among colleges in the same factor in 2016, Kruskall-Wallis: (χ 2 (3) = 1.73, p = 0.63). Analysis of responses found inconsistency among examiners regarding mistakes or omissions made when candidates were performing well. After making changes to OSCE delivery, factor scores relating to examiner stress and pressure are now improved and consistent across the surgical colleges. Stress

Special physical examination tests for superior labrum anterior-posterior shoulder injuries are clinically limited and invalid: a diagnostic systematic review. J Clin Epidemiol. 2009;62(5):558–563. Clinical Question: The systematic review focused on diagnostic accuracy studies to determine if evidence was sufficient to support the use of superior labrum anterior-posterior (SLAP) physical examination tests as valid and reliable. The primary question was whether there was sufficient evidence in the published literature to support the use of SLAP physical examination tests as valid and reliable diagnostic test procedures. Data Sources: Studies published in English were identified through database searches on MEDLINE, EMBASE, and the Cochrane database (1970–2004) using the search term SLAP lesions. The medical subject headings of arthroscopy, shoulder joint, and athletic injuries were combined with test or testing, physical examination, and sensitivity and specificity to locate additional sources. Other sources were identified by rereviewing the reference lists of included studies and review articles. Study Selection: Studies were eligible based on the following criteria: (1) published in English, (2) focused on the physical examination of SLAP lesions, and (3) presented original data. A study was excluded if the article was limited to a clinical description of 1 or more special tests without any research focus to provide clinical accuracy data or if it did not focus on the topic. Data Extraction: The abstracts that were located through the search strategies were reviewed, and potentially relevant abstracts were selected. Strict epidemiologic methods were used to obtain and collate all relevant studies; the authors developed a study questionnaire to record study name, year of publication, study design, sample size, and statistics. Validity of the diagnostic test study was determined by

Clinical characteristics combined with new biomarkers help discriminate between atypical uterine smooth muscle tumors (AUSMT) and leiomyosarcomas (LMS). We retrospectively collected a series of leiomyomas (LM), AUSMT, and LMS. Estrogen receptors (ER), progesterone receptors (PR), p16, Ki-67, and p53 expression were assessed by immunohistochemistry. For AUSMT patients, immunohistochemistry evaluations were performed at the time of diagnosis and at recurrences. A total of 27 cases of AUSMT, 22 LM, and 31 LMS were identified. The expression of ER and PR decreased from LM to LMS (ER+: LM 95.5%, AUSMT 88.9%, LMS 41.9%, p < 0.001; PR+: LM 100%, AUSMT 88.9%, LMS 38.2%, p = 0.002). By contrast, p16 and p53 expression increased (p16+: LM 4.5%, AUSMT 40.7%, LMS 45.2%, p = 0.004; p53: LM 9.1%, AUSMT 33.3%, LMS 58.1%, p = 0.001). At a median follow-up of 33.47 months, 40.7% of patients with AUSMT experienced recurrent disease, 6 patients relapsed as AUSMT and 5 as LMS. In univariate analysis was observed that ER status (p = 0.027) and p53 expression (p = 0.015) predicted risk of relapse. Treatment of AUSMT should be centralized in dedicated centers. International collaborations are needed to optimize research strategy, which may lead to the identification of new useful biomarkers and to improvement in the clinical management of this rare disease. © 2017 S.

LabRS: A Rosetta stone for retrospective standardization of clinical laboratory test results.

PubMed

Hauser, Ronald George; Quine, Douglas B; Ryder, Alex

2018-02-01

Clinical laboratories in the United States do not have an explicit result standard to report the 7 billion laboratory tests results they produce each year. The absence of standardized test results creates inefficiencies and ambiguities for secondary data users. We developed and tested a tool to standardize the results of laboratory tests in a large, multicenter clinical data warehouse. Laboratory records, each of which consisted of a laboratory result and a test identifier, from 27 diverse facilities were captured from 2000 through 2015. Each record underwent a standardization process to convert the original result into a format amenable to secondary data analysis. The standardization process included the correction of typos, normalization of categorical results, separation of inequalities from numbers, and conversion of numbers represented by words (eg, "million") to numerals. Quality control included expert review. We obtained 1.266 × 109 laboratory records and standardized 1.252 × 109 records (98.9%). Of the unique unstandardized records (78.887 × 103), most appeared <5 times (96%, eg, typos), did not have a test identifier (47%), or belonged to an esoteric test with <100 results (2%). Overall, these 3 reasons accounted for nearly all unstandardized results (98%). Current results suggest that the tool is both scalable and generalizable among diverse clinical laboratories. Based on observed trends, the tool will require ongoing maintenance to stay current with new tests and result formats. Future work to develop and implement an explicit standard for test results would reduce the need to retrospectively standardize test results. © The Author 2017.

Sequential Objective Structured Clinical Examination based on item response theory in Iran.

PubMed

Hejri, Sara Mortaz; Jalili, Mohammad

2017-01-01

In a sequential objective structured clinical examination (OSCE), all students initially take a short screening OSCE. Examinees who pass are excused from further testing, but an additional OSCE is administered to the remaining examinees. Previous investigations of sequential OSCE were based on classical test theory. We aimed to design and evaluate screening OSCEs based on item response theory (IRT). We carried out a retrospective observational study. At each station of a 10-station OSCE, the students' performance was graded on a Likert-type scale. Since the data were polytomous, the difficulty parameters, discrimination parameters, and students' ability were calculated using a graded response model. To design several screening OSCEs, we identified the 5 most difficult stations and the 5 most discriminative ones. For each test, 5, 4, or 3 stations were selected. Normal and stringent cut-scores were defined for each test. We compared the results of each of the 12 screening OSCEs to the main OSCE and calculated the positive and negative predictive values (PPV and NPV), as well as the exam cost. A total of 253 students (95.1%) passed the main OSCE, while 72.6% to 94.4% of examinees passed the screening tests. The PPV values ranged from 0.98 to 1.00, and the NPV values ranged from 0.18 to 0.59. Two tests effectively predicted the results of the main exam, resulting in financial savings of 34% to 40%. If stations with the highest IRT-based discrimination values and stringent cut-scores are utilized in the screening test, sequential OSCE can be an efficient and convenient way to conduct an OSCE.

To determine the total average costs related to laboratory examinations performed in a hospital laboratory in Chile. Retrospective study with data from July 2014 to June 2015. 92 examinations classified in ten groups were selected according to the analysis methodology. The costs were estimated as the sum of direct and indirect laboratory costs and indirect institutional factors. The average values obtained for the costs according to examination group (in USD) were: 1.79 (clinical chemistry), 10.21 (immunoassay techniques), 13.27 (coagulation), 26.06 (high-performance liquid chromatography), 21.2 (immunological), 3.85 (gases and electrolytes), 156.48 (cytogenetic), 1.38 (urine), 4.02 (automated hematological), 4.93 (manual hematological). The value, or service fee, returned to public institutions who perform laboratory services does not adequately reflect the true total average production costs of examinations.

The aim of this study is to report the development and validation of a low back computer-aided combined movement examination protocol in normal individuals and record treatment outcomes of cases with symptomatic degenerative lumbar spondylosis. Test-retest, following intervention. Self-report assessments and combined movement examination were used to record composite spinal motion, before and following neurosurgical and pain medicine interventions. 151 normal individuals aged from 20 years to 69 years were assessed using combined movement examination between L1 and S1 spinal levels to establish a reference range. Cases with degenerative low back pain and sciatica were assessed before and after therapeutic interventions with combined movement examination and a battery of self-report pain and disability questionnaires. Change scores for combined movement examination and all outcome measures were derived. Computer-aided combined movement examination validation and intraclass correlation coefficient with 95% confidence interval and least significant change scores indicated acceptable reliability of combined movement examination when recording lumbar movement in normal subjects. In both clinical cases lumbar spine movement restrictions corresponded with self-report scores for pain and disability. Post-intervention outcomes all showed significant improvement, particularly in the most restricted combined movement examination direction. This study provides normative reference data for combined movement examination that may inform future clinical studies of the technique as a convenient objective surrogate for important clinical outcomes in lumbar degenerative spondylosis. It can be used with good reliability, may be well tolerated by individuals in pain and appears to change in concert with validated measures of lumbar spinal pain, functional limitation and quality of life.

The interest in adaptive study design is evident from the growing amount of clinical research employing this model in the mid to later stages of medicines development. Little has been published on the practical application and merits of adaptive study design in early phase clinical research. This paper describes a retrospective analysis performed on a sample of 29 industry lead adaptive early phase studies commencing between 1 January 2006 and 31 December 2010 in a clinical trials unit in London, England. All studies containing at least one adaptive feature in the original protocol were included in the analysis. The scope of the analysis was to assess whether the use of adaptive study designs provided tangible benefits over the use of conventional study designs using time savings as the main measure. We conclude that the use of adaptive study design saves time in early phase research programs. This is achieved by abolishing the need for substantial amendments or by mitigating their impact on timelines and by using adaptive scheduling efficiencies.

Leishmaniasis is a parasitic disease caused by hemoflagellates of the genus Leishmania and is transmitted to humans by the bite of infected phlebotomine sandflies. Depending on the Leishmania species, the disease has different clinical forms including cutaneous, mucocutaneous, and visceral manifestations. Previous studies performed in endemic zones of northwestern-Argentina, during epidemic outbreaks, have been important for detecting patients suffering from the acute phase of the disease, but have not given a complete representation of the clinical and epidemiological features in the region. Furthermore, due to the resurgence of leishmaniasis worldwide and in particular the large increase of international tourism to the region, it seems pertinent to update the current epidemiological and clinical profile of leishmaniasis in northwestern-Argentina. Here we present a retrospective analysis of 95 Leishmania positive cases, presenting between 2000 and 2014. Patients were derived from hospitals and diagnosed in our lab at the University of Salta, located in a non-endemic area in Salta, Argentina. We detected numerous extensive mucocutaneous cases (34/95, 35.8%) distinct from mucosal affected patients, some instances originating in locations with no previously reported human cases. Additionally patients suffering from concomitant diseases, besides leishmaniasis, were assessed. These included Chagas disease, syphilis, deep mycoses, tuberculosis, toxoplasmosis and intestinal parasitosis. This study updates the clinical and epidemiological features of leishmaniasis in northwestern-Argentina, and discusses the implications and management strategy for patients who acquire the disease in this region.

2009-01-01

Objective: The American Board of Psychiatry and Neurology (ABPN) has recently replaced the traditional, centralized oral examination with the locally administered Neurology Clinical Skills Examination (NEX). The ABPN postulated the experience with the NEX would be similar to the Mini-Clinical Evaluation Exercise, a reliable and valid assessment tool. The reliability and validity of the NEX has not been established. Methods: NEX encounters were videotaped at 4 neurology programs. Local faculty and ABPN examiners graded the encounters using 2 different evaluation forms: an ABPN form and one with a contracted rating scale. Some NEX encounters were purposely failed by residents. Cohen’s kappa and intraclass correlation coefficients (ICC) were calculated for local vs ABPN examiners. Results: Ninety-eight videotaped NEX encounters of 32 residents were evaluated by 20 local faculty evaluators and 18 ABPN examiners. The interrater reliability for a determination of pass vs fail for each encounter was poor (kappa 0.32; 95% confidence interval [CI] = 0.11, 0.53). ICC between local faculty and ABPN examiners for each performance rating on the ABPN NEX form was poor to moderate (ICC range 0.14-0.44), and did not improve with the contracted rating form (ICC range 0.09-0.36). ABPN examiners were more likely than local examiners to fail residents. Conclusions: There is poor interrater reliability between local faculty and American Board of Psychiatry and Neurology examiners. A bias was detected for favorable assessment locally, which is concerning for the validity of the examination. Further study is needed to assess whether training can improve interrater reliability and offset bias.

Thoracic outlet syndrome (TOS) is a frequently overlooked peripheral nerve compression or tension event that creates difficulties for the clinician regarding diagnosis and management. Investigators have categorized this condition as vascular versus neurogenic, where vascular TOS can be subcategorized as either arterial or venous and neurogenic TOS can subcategorized as either true or disputed. The thoracic outlet anatomical container presents with several key regional components, each capable of compromising the neurovascular structures coursing within. Bony and soft tissue abnormalities, along with mechanical dysfunctions, may contribute to neurovascular compromise. Diagnosing TOS can be challenging because the symptoms vary greatly amongst patients with the disorder, thus lending to other conditions including a double crush syndrome. A careful history and thorough clinical examination are the most important components in establishing the diagnosis of TOS. Specific clinical tests, whose accuracy has been documented, can be used to support a clinical diagnosis, especially when a cluster of positive tests are witnessed. PMID:21655389

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. We aimed to assess feasibility and performance of CBE by laywomen in urban health clinics in Malawi. 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 y, 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 = 0.012). Among 1000 women screened, 7% had abnormal CBE. Of 45 women with normal CBE randomized 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%).

To evaluate the validity of retrospective disease activity assessment derived from clinical charts. We prospectively evaluated 37 patients with systemic lupus erythematosus (SLE) in 90 visits using the SLE Disease Activity Index (SLEDAI), the Mexican SLEDAI (Mex-SLEDAI), and the Lupus Activity Criteria Count (LACC) indices. Routine clinical observations were written by rheumatologists blind to index scores. These notes were reviewed 2 years later to obtain retrospective index scores and their validity was assessed using prospective scores as the standard. Statistical analysis was by Spearman's rank correlation coefficient (rs), Wilcoxon matched pairs test, kappa statistic, and intraclass correlation coefficient (ri). We calculated the sensitivity and specificity of retrospective indices to detect active disease. Median retrospective scores were lower in all indices: SLEDAI (4 VS 2, p =0.004, RS = 0.68, ri = 0.30); Mex-SLEDAI (2 vs 1, p < 0.0003, rs = 0.79, ri = 0.31); and LACC (1 vs 1, p = 0.007, rs = 0.65, ri = 0.21). Used to detect active SLE, the retrospective SLEDAI had a sensitivity of 0.68 and a specificity of 0.86; corresponding values for the Mex-SLEDAI were 0.72 and 0.91, and for the LACC, 0.77 and 0.76. Retrospective disease activity indices tended to provide lower scores than prospective evaluations. They often missed patients with mildly active disease, but when positive they were good predictors of disease activity.

The American Society for Clinical Pathology resident in-service examination: does resident performance provide insight into the effectiveness of clinical pathology education?

PubMed

McKenna, Barbara J

2007-06-01

The resident in-service examination in pathology is an in-training exercise that is taken by virtually all pathology residents in the United States as well as by some participants in Canada, Ireland, and Lebanon. Although all of the anatomic pathology topics in the examination, with only one exception-forensic pathology, show significant improvement in scores over the 4 years of residency training, three areas of clinical pathology training (laboratory administration, clinical chemistry, and microbiology) show significantly lower improvement in performance over the years of residency training. By contrast, transfusion medicine, hematopathology and the special topics section of the examination all demonstrate improved performance by residents over time. While the reason behind these differences must remain speculative at this time, these findings suggest that measures to improve effectiveness in clinical pathology training might be suggested by examining the differences between residency training practices between higher and lower performing areas of clinical pathology.

The aim of this retrospective study was to determine the clinical and the radiographic outcomes of dental implants placed in elderly people older than 65 years. In total, 902 implants in 346 patients (age: 65-89 years) were followed up for 2-17 years following the implant surgery. The survival rate of these implants was recorded and analyzed. Changes in marginal bone levels were also analyzed in serial radiographs, and Cox regression analysis for implant loss was performed. The survival rates were 95.39% and 99.98% in the implant- and patient-based analyses, respectively (involving a total of 29 implant failures), and the marginal bone loss at the implants was 0.17 ± 0.71 mm (mean ± SD). The number of failures was greatest in patients aged 65-69 years. The Cox regression with shared frailty analysis showed that implant loss was significantly greater in those aged 65-69 years than in those aged 70-74 years (P < 0.05), and it varied between specific implant systems. Within the limitations of this retrospective study, it was concluded that implant therapy can be successfully provided to elderly patients and that age alone does not seem to affect the implant survival rate. © 2016 John Wiley & Sons A/S.

Objective Structured Clinical Evaluation (OSCE) is an excellent method to evaluate student's abilities, but there are no previous reports implementing it in dermatology. To determine the feasibility of implementation of a dermatology OSCE in the medical school. Five stations with standardized patients and image-based assessment were designed. A specific checklist was elaborated in each station with different items which evaluated one competency and were classified into five groups (medical history, physical examination, technical skills, case management and prevention). A total of 28 students were tested. Twenty-five of them (83.3%) passed the exam globally. Concerning each group of items tested: medical interrogation had a mean score of 71.0; physical examination had a mean score of 63.0; management had a mean score of 58.0; and prevention had a mean score of 58.0 points. The highest results were obtained in interpersonal skills items with 91.8 points. Testing a small sample of voluntary students may hinder generalization of our study. OSCE is an useful tool for assessing clinical skills in dermatology and it is possible to carry it out. Our experience enhances that medical school curriculum needs to establish OSCE as an assessment tool in dermatology. Copyright © 2016 AEDV. Publicado por Elsevier España, S.L.U. All rights reserved.

The predictive validity of the BioMedical Admissions Test for pre-clinical examination performance.

PubMed

Emery, Joanne L; Bell, John F

2009-06-01

Some medical courses in the UK have many more applicants than places and almost all applicants have the highest possible previous and predicted examination grades. The BioMedical Admissions Test (BMAT) was designed to assist in the student selection process specifically for a number of 'traditional' medical courses with clear pre-clinical and clinical phases and a strong focus on science teaching in the early years. It is intended to supplement the information provided by examination results, interviews and personal statements. This paper reports on the predictive validity of the BMAT and its predecessor, the Medical and Veterinary Admissions Test. Results from the earliest 4 years of the test (2000-2003) were matched to the pre-clinical examination results of those accepted onto the medical course at the University of Cambridge. Correlation and logistic regression analyses were performed for each cohort. Section 2 of the test ('Scientific Knowledge') correlated more strongly with examination marks than did Section 1 ('Aptitude and Skills'). It also had a stronger relationship with the probability of achieving the highest examination class. The BMAT and its predecessor demonstrate predictive validity for the pre-clinical years of the medical course at the University of Cambridge. The test identifies important differences in skills and knowledge between candidates, not shown by their previous attainment, which predict their examination performance. It is thus a valid source of additional admissions information for medical courses with a strong scientific emphasis when previous attainment is very high.

Calvert E, Chambers GK, Regan W, Hawkins RH, Leith JM. Special physical examination tests for superior labrum anterior-posterior shoulder injuries are clinically limited and invalid: a diagnostic systematic review. J Clin Epidemiol. 2009;62(5):558-563. The systematic review focused on diagnostic accuracy studies to determine if evidence was sufficient to support the use of superior labrum anterior-posterior (SLAP) physical examination tests as valid and reliable. The primary question was whether there was sufficient evidence in the published literature to support the use of SLAP physical examination tests as valid and reliable diagnostic test procedures. Studies published in English were identified through database searches on MEDLINE, EMBASE, and the Cochrane database (1970-2004) using the search term SLAP lesions. The medical subject headings of arthroscopy, shoulder joint, and athletic injuries were combined with test or testing, physical examination, and sensitivity and specificity to locate additional sources. Other sources were identified by rereviewing the reference lists of included studies and review articles. Studies were eligible based on the following criteria: (1) published in English, (2) focused on the physical examination of SLAP lesions, and (3) presented original data. A study was excluded if the article was limited to a clinical description of 1 or more special tests without any research focus to provide clinical accuracy data or if it did not focus on the topic. The abstracts that were located through the search strategies were reviewed, and potentially relevant abstracts were selected. Strict epidemiologic methods were used to obtain and collate all relevant studies; the authors developed a study questionnaire to record study name, year of publication, study design, sample size, and statistics. Validity of the diagnostic test study was determined by applying the 5 criteria proposed by Calvert et al. If the study met the inclusion and validity

Good knowledge on the interactions between climatic variables and malaria can be very useful for predicting outbreaks and preparedness interventions. We investigated clinical malaria transmission patterns and its temporal relationship with climatic variables in Tubu village, Botswana. A 5-year retrospective time series data analysis was conducted to determine the transmission patterns of clinical malaria cases at Tubu Health Post and its relationship with rainfall, flood discharge, flood extent, mean minimum, maximum and average temperatures. Data was obtained from clinical records and respective institutions for the period July 2005 to June 2010, presented graphically and analysed using the Univariate ANOVA and Pearson cross-correlation coefficient tests. Peak malaria season occurred between October and May with the highest cumulative incidence of clinical malaria cases being recorded in February. Most of the cases were individuals aged >5 years. Associations between the incidence of clinical malaria cases and several factors were strong at lag periods of 1 month; rainfall (r = 0.417), mean minimum temperature (r = 0.537), mean average temperature (r = 0.493); and at lag period of 6 months for flood extent (r = 0.467) and zero month for flood discharge (r = 0.497). The effect of mean maximum temperature was strongest at 2-month lag period (r = 0.328). Although malaria transmission patterns varied from year to year the trends were similar to those observed in sub-Saharan Africa. Age group >5 years experienced the greatest burden of clinical malaria probably due to the effects of the national malaria elimination programme. Rainfall, flood discharge and extent, mean minimum and mean average temperatures showed some correlation with the incidence of clinical malaria cases.

Nasal vestibulitis (NV) is a common infection; however, scant data is available in the literature as it pertains to NV. We aim to describe the clinical characteristics of NV in respect to its potential complications. A retrospective chart review of 118 NV cases admitted to a tertiary medical center between 2008 and 2015. Identified risk factors for NV included nasal hair plucking (n=15, 14.41%), nose blowing (n=10, 9.32%), nose picking (n=9, 8.47%) and nose piercing (n=5, 3.39%). Twelve patients (10.17%) were diabetic, and 3 patients were immunosuppressed. Mid-facial cellulitis was observed in the majority of patients (78.81%), and abscess of the nasal vestibule was observed in almost half (48.30%). Cultures were taken from 33.33% of patients demonstrated MSSA as the most common isolate (81.25%). No complications were observed. Even in complicated cases of NV requiring admission, the risk of major complications is extremely low. Copyright © 2017 Elsevier Inc. All rights reserved.

Previous biomechanical studies have shown that the gift box technique for open Achilles tendon repair is twice as strong as a Krackow repair. The technique incorporates a paramedian skin incision with a midline paratenon incision, and a modification of the Krackow stitch is used to reinforce the repair. The wound is closed in layers such that the paratenon repair is offset from paramedian skin incision, further protecting the repair. The present study retrospectively reviews the clinical results for a series of patients who underwent the gift box technique for treatment of acute Achilles tendon ruptures from March 2002 to April 2007. The patients completed the Foot Function Index and the American Orthopaedic Foot and Ankle Society ankle-hindfoot scale. The tendon width and calf circumference were measured bilaterally and compared using paired t tests with a 5% α level. A total of 44 subjects, mean age 37.5 ± 8.6 years, underwent surgery approximately 10.8 ± 6.5 days after injury. The response rate was 35 (79.54%) patients for the questionnaire and 20 (45.45%) for the examination. The mean follow-up period was 35.7 ± 20.1 months. The complications included one stitch abscess, persistent pain, and keloid formation. One (2.86%) respondent reported significant weakness. Five (14.29%) respondents indicated persistent peri-incisional numbness. The range of motion was full or adequate. The mean American Orthopaedic Foot and Ankle Society ankle-hindfoot scale score was 93.2 ± 6.8) and the mean Foot Function Index score was 7.0 ± 10.5. The calf girth and tendon width differences were statistically significantly between the limbs. The patients reported no repeat ruptures, sural nerve injuries, dehiscence, or infections. We present the outcomes data from patients who had undergone this alternative technique for Achilles tendon repair. The technique is reproducible, with good patient satisfaction and return to activity. The results compared well with the historical

The competent physical examination of patients and the safe and professional implementation of clinical procedures constitute essential components of medical practice in nearly all areas of medicine. The central objective of the projects "Heidelberg standard examination" and "Heidelberg standard procedures", which were initiated by students, was to establish uniform interdisciplinary standards for physical examination and clinical procedures, and to distribute them in coordination with all clinical disciplines at the Heidelberg University Hospital. The presented project report illuminates the background of the initiative and its methodological implementation. Moreover, it describes the multimedia documentation in the form of pocketbooks and a multimedia internet-based platform, as well as the integration into the curriculum. The project presentation aims to provide orientation and action guidelines to facilitate similar processes in other faculties.

Patients increasingly benefit from immunosuppressive/immunomodulatory medications for a range of conditions allowing them a lifestyle similar to healthy individuals, including travel. However, the administration of live vaccines to immunodeficient patients bears the risk of replication of the attenuated vaccine microorganism. Therefore, live vaccines are generally contraindicated on immunosuppression. Data on live vaccinations on immunosuppressive/immunomodulatory medication are scarce. We identified all travellers seeking pre-travel advice in three Swiss travel clinics with a live vaccine during immunosuppressive/immunomodulatory therapy to ascertain experienced side effects. A retrospective and multi-centre study design was chosen to increase the sample size. This study was conducted in the travel clinics of the University of Zurich; the Swiss TPH, Basel; and Geneva University Hospitals. Travellers on immunosuppressive/immunomodulatory therapy who received live vaccines [yellow fever vaccination (YFV), measles/mumps/rubella (MMR), varicella and/ or oral typhoid vaccination (OTV)] between 2008 and 2015 were identified and interviewed. A total of 60 age- and sex-matched controls (matched to Basel/Zurich travel clinics travellers) were included. Overall, 197 patients were identified. And 116 patients (59%) and 60 controls were interviewed. YFV was administered 92 times, MMR 21 times, varicella 4 times and OTV 6 times to patients on immunosuppressive/immunomodulatory therapy. Most common medications were corticosteroids (n = 45), mesalazine (n = 28) and methotrexate (n = 19). Live vaccines were also administered on biological treatment, e.g. TNF-alpha inhibitors (n = 8). Systemic reactions were observed in 12.2% of the immunosuppressed vs 13.3% of controls; local reactions in 7.8% of the immunosuppressed vs 11.7% of controls. In controls, all reactions were mild/moderate. In the immunosuppressed, 2/21 severe reactions occurred: severe local pain on interferon

Construct: We investigated the extent of the associations between medical students' clinical competency measured by performance in Objective Structured Clinical Examinations (OSCE) during Obstetrics/Gynecology and Family Medicine clerkships and later performance in both undergraduate and graduate medical education. There is a relative dearth of studies on the correlations between undergraduate OSCE scores and future exam performance within either undergraduate or graduate medical education and almost none on linking these simulated encounters to eventual patient care. Of the research studies that do correlate clerkship OSCE scores with future performance, these often have a small sample size and/or include only 1 clerkship. Students in USU graduating classes of 2007 through 2011 participated in the study. We investigated correlations between clerkship OSCE grades with United States Medical Licensing Examination Step 2 Clinical Knowledge, Clinical Skills, and Step 3 Exams scores as well as Postgraduate Year 1 program director's evaluation scores on Medical Expertise and Professionalism. We also conducted contingency table analysis to examine the associations between poor performance on clerkship OSCEs with failing Step 3 and receiving poor program director ratings. The correlation coefficients were weak between the clerkship OSCE grades and the outcomes. The strongest correlations existed between the clerkship OSCE grades and the Step 2 CS Integrated Clinical Encounter component score, Step 2 Clinical Skills, and Step 3 scores. Contingency table associations between poor performances on both clerkships OSCEs and poor Postgraduate Year 1 Program Director ratings were significant. The results of this study provide additional but limited validity evidence for the use of OSCEs during clinical clerkships given their associations with subsequent performance measures.

To compare survival rates among dental implants restored with immediate, early, and conventional loading protocols, also comparing between maxillary and mandibular implants, and to evaluate the influence of implant length and diameter and the type of prosthesis on treatment outcomes. This retrospective cohort study initially included all 52 patients receiving dental implants between July 2006 and February 2008 at a private oral surgery clinic in Granada (Southern Spain). Clinical and radiographic examinations were performed, including periapical or panoramic radiographs, and incidences during completion of the restoration were recorded at 1 week, 3 months, 6 months, and at 1, 2, 3, 4, and 5 years. After a 5-year follow-up, 1 patient had died, 3 were lost to follow-up, and 6 required grafting before implant placement; therefore, the final study sample comprised 42 patients with 164 implants. Variables associated with the survival/failure of the restoration were: number of implants (higher failure rate with fewer implants), bone type (higher failure rate in type III or IV bone), and type of prosthesis (higher failure rate with single crowns). No significant association was found in univariate or multivariate analyses between survival rate and the loading protocol, implant length or diameter, or maxillary/mandibular location. Immediate occlusal loading, immediate provisionalization without occlusal loading, and early loading are viable treatment options with similar survival rates to those obtained with conventional loading. Bone quality and number of implants per patient were the most influential factors. © 2015 by the American College of Prosthodontists.

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

Richter's syndrome (RS) is the rare development of an aggressive lymphoid malignancy in a patient with pre-existing chronic lymphocytic leukemia (CLL). Data on RS is sparse and mostly derived from case reports or small series of patients and only a few larger cohorts have been published. The purpose of this large retrospective study was to summarize our national experience with RS in CLL, examine possible risk factors, and analyze relevant demographic, laboratory and clinical parameters, including results of therapy and outcome. We first evaluated data obtained from 119 patients with RS diagnosed during 1971-2010 from 12 medical centers in Israel. The final cohort summarized consisted of 81 patients with RS who developed only diffuse large B-cell lymphoma (DLBCL) after exclusion all cases with insufficient data and those who were not DLBCL. Median overall survival from time of diagnosis of RS was 8 months; after applying the Richter score, patients could be stratified into three prognostic groups, while all other clinical and laboratory parameters evaluated had no prognostic significance. Prior therapy for CLL had no impact on RS survival (P = 0.8) and patients with therapy "naïve" RS and those who had already received chemotherapy prior to developing RS, had the same survival. The addition of rituximab to chemotherapy for RS improved 2 years overall survival from 19% in the chemotherapy alone arm to 42% (P value of 0.001). Although prognosis of patients with RS remains dismal, this retrospective observation provides support for the use of chemo-immunotherapy in DLBCL-RS. © 2014 Wiley Periodicals, Inc.

2001-06-01

Although evidence-based guidelines are beginning to be produced as to which psychological therapies might be appropriate for which patients, little is known about how general medical practitioners (GPs) in practice distribute referrals between different psychological therapy services. In a retrospective survey, 19 practice counsellors and 10 clinical psychologists from the same geographical area rated a year's caseload of GP referrals using identical data collection methods. Rated casemix was found to be broadly similar, although practice counsellors rated relationship and bereavement problems as more common in their caseloads (totalling 986 patients), and clinical psychologists rated panic disorder, phobias, and obsessive-compulsive problems as more common in their caseloads (totalling 320 patients). Depression and anxiety reactions were the most common problems rated in both groups, but the clinical psychologist cases of depression were rated as more severe and complex. Where differences were found, they may have reflected the different ways that counsellors and clinical psychologists conceptualize cases rather than actual differences in casemix. The results are discussed in relation to evidence-based guideline recommendations about cases appropriate to be seen by practice counsellors and by clinical psychologists in primary and secondary care, and the need to adapt such guidance to local services and skills of practitioners.

Hip Dysplasia: Clinical Signs and Physical Examination Findings.

PubMed

Syrcle, Jason

2017-07-01

Hip dysplasia is a common developmental disorder of the dog, consisting of varying degrees of hip laxity, progressive remodeling of the structures of the hip, and subsequent development of osteoarthritis. It is a juvenile-onset condition, with clinical signs often first evident at 4 to 12 months of age. A tentative diagnosis of hip dysplasia can be made based on signalment, history, and physical examination findings. The Ortolani test is a valuable tool for identifying juvenile dogs affected with this condition. Further diagnostics can then be prioritized, contributing to prompt diagnosis and appropriate treatment. Copyright © 2017 Elsevier Inc. All rights reserved.

2016-01-01

Study Objectives: Narcolepsy and idiopathic hypersomnia are commonly treated by sleep specialists and encountered by other medical providers. Although pharmacotherapy with modafinil and traditional stimulants is considered the mainstay of treatment, physicians are often uncomfortable with their prescription because of concerns regarding misuse. The goal of this study was to assess the frequency of stimulant misuse in this population. Methods: A retrospective cohort study was performed evaluating patients 18 years and older diagnosed with narcolepsy with and without cataplexy and idiopathic hypersomnia with and without long sleep between 2003–2008. Patients were included if they obtained stimulant prescriptions from and had at least one follow-up visit subsequent to initial diagnosis at our center. Stimulant misuse was defined by multiple prescription sources or early refill requests, which are systematically entered into the record by nursing staff. Results: A total of 105 patients met inclusion criteria for the study; 45 (42%) were male. Mean age at multiple sleep latency test was 42 (± 16). Twelve (11%) patients had a history of illicit substance misuse, and one (1%) patient demonstrated previous stimulant misuse. Fifty-seven (54%) patients carried psychiatric diagnoses, 88% of whom reported depression. Median duration of monitored stimulant therapy was 26 months (range 1–250). None of the 105 patients was found to have evidence of stimulant misuse. Conclusion: This study suggests that the frequency of stimulant misuse in patients with narcolepsy and idiopathic hypersomnia is extremely low. Concerns regarding drug misuse should not leverage decisions to provide long-term therapy. Citation: Mantyh WG, Auger RR, Morgenthaler TI, Silber MH, Moore WR.

Why some individuals with ankle sprains develop functional ankle instability and others do not (ie, copers) is unknown. Current understanding of the clinical profile of copers is limited. To contrast individuals with functional ankle instability (FAI), copers, and uninjured individuals on both self-reported variables and clinical examination findings. Cross-sectional study. Sports medicine research laboratory. Participants consisted of 23 individuals with a history of 1 or more ankle sprains and at least 2 episodes of giving way in the past year (FAI: Cumberland Ankle Instability Tool [CAIT] score = 20.52 ± 2.94, episodes of giving way = 5.8 ± 8.4 per month), 23 individuals with a history of a single ankle sprain and no subsequent episodes of instability (copers: CAIT score = 27.74 ± 1.69), and 23 individuals with no history of ankle sprain and no instability (uninjured: CAIT score = 28.78 ± 1.78). Self-reported disability was recorded using the CAIT and Foot and Ankle Ability Measure for Activities of Daily Living and for Sports. On clinical examination, ligamentous laxity and tenderness, range of motion (ROM), and pain at end ROM were recorded. Questionnaire scores for the CAIT, Foot and Ankle Ability Measure for Activities of Daily Living and for Sports, ankle inversion and anterior drawer laxity scores, pain with palpation of the lateral ligaments, ankle ROM, and pain at end ROM. Individuals with FAI had greater self-reported disability for all measures (P < .05). On clinical examination, individuals with FAI were more likely to have greater talar tilt laxity, pain with inversion, and limited sagittal-plane ROM than copers (P < .05). Differences in both self-reported disability and clinical examination variables distinguished individuals with FAI from copers at least 1 year after injury. Whether the deficits could be detected immediately postinjury to prospectively identify potential copers is unknown.

The Objective Structured Clinical Examination (OSCE) is a widely used measurement tool to assess clinical competence in the health sciences. There is little published evidence of its use in Mexican medical schools. To assess clinical competence in medical students with an OSCE, before and after the Medical Internship. Prospective cohort study, pre- post-test research design. The assessed population was medical students at UNAM Faculty of Medicine in Mexico in their Internship year. The instrument was an 18-stations OSCE, three stations per academic area of the Internship curriculum. We assessed the clinical competence of 278 students in a pretest OSCE when starting the Internship year, and tested them 10 months later with an equivalent post-test OSCE. The sample of students was 30.4% of the total Internship population. Test reliability with Cronbach's alpha was 0.62 in the pre-test and 0.64 in the post-test. The global mean score in the pretest OSCE was 55.6 ± 6.6 and in the post-test 63.2 ± 5.7 (p < 0.001), with a Cohen's d of 1.2. The clinical competence of medical students measured with an OSCE is higher after the medical internship year. This difference suggests that the internship can influence the development of clinical competence in medical students.

Aim: To analyze clinical data from male patients treated with urethrotomy and to develop a clinical decision algorithm. Materials and methods: Two large cohorts of male patients with urethral strictures were included in this retrospective study, historical (1985-1995, n=491) and modern cohorts (1996-2006, n=470). All patients were treated with repeated internal urethrotomies (up to 9 sessions). Clinical outcomes were analyzed and systemized as a clinical decision algorithm. Results: The overall recurrence rates after the first urethrotomy were 32.4% and 23% in the historical and modern cohorts, respectively. In many patients, the second procedure was also effective with the third procedure also feasible in selected patients. The strictures with a length ≤ 2 cm should be treated according to the initial length. In patients with strictures ≤ 1 cm, the second session could be recommended in all patients, but not with penile strictures, strictures related to transurethral operations or for patients who were 31-50 years of age. The third session could be effective in selected cases of idiopathic bulbar strictures. For strictures with a length of 1-2 cm, a second operation is possible for the solitary low-grade bulbar strictures, given that the age is > 50 years and the etiology is not post-transurethral resection of the prostate. For penile strictures that are 1-2 cm, urethrotomy could be attempted in solitary but not in high-grade strictures. Conclusions: We present data on the treatment of urethral strictures with urethrotomy from a single center. Based on the analysis, a clinical decision algorithm was suggested, which could be a reliable basis for everyday clinical practice. PMID:28529689

To further understand management of pediatric patients with multiple sclerosis (MS), we examined disease features, clinical practice patterns, and response to treatment in the United States (US) and seven other countries ('rest of World'; ROW). Anonymized data, recorded as part of routine clinical practice, were obtained from medical records (1997-2009) of study participants (who received subcutaneous interferon β-1a before age 18 years) from the US and ROW. Samples were stratified by age (preadolescents [<12 years] and adolescents [12-17 years]). US adolescents had a higher mean body mass index versus ROW adolescents (BMI; 27.2 versus 22.5 kg/m(2)), started disease-modifying therapy (DMT) earlier after the first relapse, were more likely to have received a DMT before initiating subcutaneous interferon β-1a, had a higher relapse rate, and were more likely to switch from subcutaneous interferon β-1a to another DMT before the end of the observation period. This retrospective analysis of a multinational sample of pediatric MS patients who received subcutaneous interferon β-1a found that those from the US had higher BMI, relapsed more frequently, and were managed differently, compared with ROW patients. Future prospective studies are needed to confirm these observations and ascertain their clinical significance. Copyright © 2016 The Authors. Published by Elsevier B.V. All rights reserved.

Evidence suggests that individuals with Alzheimer's disease (AD) are often diagnosed in the later stages of their disease with a poor prognosis. This study aimed to identify patterns in signs and symptoms preceding the clinical diagnosis of AD to suggest a predictive model for earlier diagnosis of the disease in the primary care. A retrospective medical record review; nested case control design. Participants included one hundred and nine patients from three general practice (GP) surgeries in Milton Keynes and Luton Clinical Commissioning groups (CCG) (37 cases with AD and 72 controls without AD). A retrospective analysis using the logistic regression of the presence of signs and symptoms before the diagnosis of AD was attained. Identification of the timing and sequence of appearance of these presentations as first reported before the clinical diagnosis was measured. Episodic memory with an odds ratio of 1.85 was the most frequent presentation, documented in 1.38% of the controls and 75.6% in cases. Auditory disturbance with an odds ratio of 3.03, which has not previously been noted except in the form of auditory hallucination, could have a diagnostic value. Auditory disturbance, which occurred mostly in the Caucasian females, could discriminate individuals with AD from those without. The symptom, which presented up to 14.5 (mean time) years prior to clinical diagnosis, was identified in Caucasians and mixed race individuals only.

Serum ferritin has long known as an acute phase reactant during inflammation. It works as an oxidative stress marker beside its role in the storage of intracellular iron. The increase of serum ferritin levels (SFL) has been reported found in HIV patients. It remains unclear though whether it causes, or is the cause, to the progressivity of the disease. The purpose of this study was to find the association between the SFL and the progressivity of the HIV disease. A retrospective study of 91 patients was carried out at the Haji Adam Malik Central General Hospital. All of the study population were HIV positive inpatients admitted from January to December 2016. The data needed to be all obtained from the patient’s medical records. The WHO Clinical Staging System was used to assess the HIV clinical staging. An inverse relationship was found between the SFL with the immunological status of the HIV patients (r=-0.213) based on their CD4+ count. There was no association found between the SFL with the clinical staging of the HIV patients (p=0.953). The elevated SFL is a feature found in HIV-diagnosed patients with the low CD4+ count, and it affects the progressivity of the disease.

Gastrointestinal stromal tumors (GISTs) are rare malignancies but the most common mesenchymal tumors of the digestive tract. Recent advances in diagnostic imaging and an increasing incidence will confront us more frequently with stromal tumors. This single center study aimed to characterize GIST patients in terms of tumor location, clinical presentation, metastasis formation, as well as associated secondary malignancies. In a retrospective study, 104 patients with a histologically confirmed diagnosis of GIST, collected between 1993 and 2011, were characterized for several clinical features. The most common GIST location was the stomach (67.6%) followed by the small intestine (16.2%). Gastrointestinal bleeding (55.8%) and abdominal pain (38.5%) were the most frequently reported symptoms whereas about one-third of patients remained clinically asymptomatic (31.6%); 14.4% of patients had either synchronous or metachronous metastases and there was a significant prevalence also in the low risk group. The proportion of secondary malignant associated neoplasms was 31% in our GIST cohort, among which gastrointestinal, genitourinary tumors, and breast cancer were the most prevalent. There was a considerable risk for metastasis formation and the development of secondary neoplasias that should encourage discussion about the appropriate surveillance strategy after surgery for GIST. © 2018 S.

To compare the sensitivity of physical examination (internal rotation of the hip) with radiographs (using the Kellgren-Lawrence grading scale) in the diagnosis of clinically significant hip osteoarthritis. Case Series, Retrospective chart review of hip pain patients that underwent fluoroscopically guided hip steroid and anesthetic injections. 10 patients with hip pain patients seen at an academic outpatient center over a 2 year period were analyzed. Fluoroscopically guided hip steroid and anesthetic injection. Pain relief and change in VAS pain score after intra-articular hip steroid and lidocaine injection was the main outcome measure. Based on Fisher's exact test, there was no association between severity of radiographic hip arthritis and pain relief with intra-articular anesthetic/steroid injection (p=0.45). Physical examination (provocative hip internal rotation) however was associated with a significant decrease in VAS pain score after intra-articular lidocaine and corticosteroid hip injection (p=0.022). Simple hip radiographs alone are not sufficient to diagnose clinically significant hip osteoarthritis. Physical examination (hip internal rotation) was found to be more accurate than simple radiographs in the diagnosis of clinically significant hip osteoarthritis. Radiographs seem to best utilized when they are an extension of the physical examination and patient history.

Increased use of smartphone and related software applications has created a new era in clinical data exchange among patients and clinicians. This study describes use of the smartphone-based application WhatsApp to share clinical oral medicine information. Clinical images and related questions were submitted by general dentists, physicians, dental hygienists, and patients to the authors via WhatsApp. For each submission, a clinical impression was made and categorized as traumatic, infective, neoplastic, autoimmune, or unclassified. Submissions were summarized by sender type, number of photographs per sender, and category of question. Patients were invited to undergo a clinical examination with biopsy, when indicated. The telemedicine impression was compared to the clinicopathologic diagnosis. Three hundred and thirty-nine images were received for 96 patients; 92 (95.8%) patients underwent clinicopathologic examination, and 45 (49%) received a biopsy. General dentists (62%) and dental hygienists (26%) were the most frequent senders. The most common question was related to diagnosis (56%). The telemedicine impression agreed with the clinicopathologic assessment for 82% of cases. Telemedicine applications, such as WhatsApp, can support communication about oral conditions among clinicians and patients. Telemedicine consultation reduced geographic barriers to initial clinical consultation and encouraged the significant majority of patients to pursue expert clinical examination.

Patients with diabetic foot ulcers (DFU) have an increased risk of lower extremity amputation. A retrospective chart review of patients with DFUs attending the Foot Treatment and Assessment chiropodist-led outpatient clinic at an inner-city academic hospital was conducted to determine wound healing outcomes and characteristics contributing to outcomes. We reviewed the complete clinical history of 279 patients with 332 DFUs spanning over a five-year period. The mean age of patients was 61.5±12.5 years and most patients (83.5%) had one DFU. The majority of wounds (82.5%) were in the forefoot. Overall, 267/332 (80.5%) wounds healed. A greater proportion of wounds healed in the forefoot (82.5%) and midfoot (87.1%) than hindfoot (51.9%; p<0.001). Using a logistic regression model, palpable pedal pulse and use of a total contact cast were associated with better wound healing. Our findings are the first to demonstrate the benefits of chiropodists leading an acute care outpatient clinic in the management of DFUs in Canada and delivers wound healing outcomes equivalent to or exceeding those previously published.

Does studying for an objective structured clinical examination make a difference?

Mavis, B E

2000-10-01

This study examines the extent to which second-year medical students studied for an objective structured clinical examination (OSCE), how they studied, and the impact of self-reported studying on OSCE performance. One class of 113 medical students completed an end-of-second-year OSCE, held on two consecutive evenings. The OSCE was comprised of eight stations, each of which was of 20 minutes' duration. The OSCE was formative: students received performance feedback but were not graded. Prior to the OSCE, students completed a brief survey regarding their preparation for the OSCE and their perceptions of confidence, anxiety and preparedness. Only 78 students returned surveys with names, comprising the data for these analyses. Mean studying time was 3.3 h, ranging from 0 to 19 h. Studying time was positively associated with age and negatively associated with basic science examination scores. The most study time was dedicated to reviewing the physical examination textbook, class notes and supplemental course readings. The breadth of study strategies increased as more time was spent in OSCE preparation. OSCE performance was related to study time and to achievement on pre-clinical basic science examinations. The students whose performance was above average seemed to be the talented students whose records indicated a history of academic success. The amount of time they reported for OSCE preparation was comparable to that reported by students with below average performance. It appears that prior academic performance rather than preparatory studying time is a better predictor of OSCE outcomes.

The aim of this study was to analyze retrospectively the influence of different acoustic and language models in order to determine the most important effects to the clinical performance of an Estonian language-based non-commercial radiology-oriented automatic speech recognition (ASR) system. An ASR system was developed for Estonian language in radiology domain by utilizing open-source software components (Kaldi toolkit, Thrax). The ASR system was trained with the real radiology text reports and dictations collected during development phases. The final version of the ASR system was tested by 11 radiologists who dictated 219 reports in total, in spontaneous manner in a real clinical environment. The audio files collected in the final phase were used to measure the performance of different versions of the ASR system retrospectively. ASR system versions were evaluated by word error rate (WER) for each speaker and modality and by WER difference for the first and the last version of the ASR system. Total average WER for the final version throughout all material was improved from 18.4% of the first version (v1) to 5.8% of the last (v8) version which corresponds to relative improvement of 68.5%. WER improvement was strongly related to modality and radiologist. In summary, the performance of the final ASR system version was close to optimal, delivering similar results to all modalities and being independent on user, the complexity of the radiology reports, user experience, and speech characteristics.

Exposure to asbestos results in serious risks of developing mesothelioma and lung cancer. The link between asbestos exposure and lung carcinoma is well established. Nevertheless, precise histopathological data are poorly considered when investigating the asbestos-cancer link in a compensatory approach. In the present study, we aim to describe the features of individuals with compensated lung cancer who were referred to an occupational disease center, regarding occupational exposure to asbestos, smoking history and pathological data. We led a retrospective study of compensated ARLC cases seen in our occupational disease center between 2003 and 2013. A total of 146 men were included (mean age at diagnosis, 63.2 years) of whom approximately 90% were heavy current or former smokers (mean value, 30.4 packs/year). The major industries associated with the lung cancer cases were shipbuilding (69.9%), and building construction (7.5%) in this harbor region. The results of the present study showed that lung upper lobe was most prevalent (61.6%) and an excess of adenocarcinoma was found (45.9%), followed by squamous cell carcinoma (38.4%) as well as thoracic sarcomas (2.1%). Neoplasm was not histologically proven in 6.8% of the cases. Subsequent pathology examinations also reclassified 2 tumors as metastases from esophageal and laryngeal origins. In conclusion, smoking prevention should be encouraged in asbestos-exposed workers as reflected by the number of smokers with asbestos-related lung cancer. Thus, histological data should be considered further to evaluate the potent relationship between asbestos exposure and lung malignancy, especially in a compensatory approach.

Patients with peripheral and central nervous system diseases may suffer from different types of pain, namely nociceptive, neuropathic and mixed pain. Although in some cases, the distinction between these types of pain is clinically evident, yet in some patients an accurate differential diagnosis requires dedicated clinical examination, screening questionnaires and diagnostic techniques some of which are available only in specialized pain centres. This review briefly addresses the currently agreed definitions of the different types of pain and shows how clinical examination, pain questionnaires and diagnostic tests can help the clinicians in identifying neuropathic pain.

Patient-Centered Bedside Rounds and the Clinical Examination.

Bedside hospital rounds promote patient-centered care in teaching and nonteaching settings. Patients and families prefer bedside rounds and provider acceptance is increasing. Efficient bedside rounds with an interprofessional team or with learners requires preparation of the patient and the rounding team. Bedside "choreography" provides structure and sets expectations for time spent in the room. By using relationship-centered communication, rounds can be both patient proximate and patient centered. The clinical examination can be integrated into the flow of the presentation and case discussion. Patient and provider experience can be enhanced through investing time at the bedside.

2006-01-01

Salvia miltiorrhiza (Labiatae, Laminaceae), danshen, is an annual sage mainly found in China and neighboring countries. The crude drug (dried root) and its preparations are currently used in China to treat patients suffering from heart attack, angina pectoris, stroke and some other conditions. The use of S. miltiorrhiza has been increasing in the management of stroke. Pharmacological examinations showed that the plant and its active ingredients, tanshinones and salvianolic acids, have anticoagulant, vasodilatory, increased blood flow, anti-inflammatory, free radical scavenging, mitochondrial protective and other activities. This review discusses the pharmacology, medicinal chemistry and clinical studies published, especially in China, for danshen and tanshinone preparations. Clinical examinations are evaluated in terms of S. miltiorrhiza preparation, dose, double blinding, control, clinical assessments of outcomes and other parameters. Meta-analyses of S. miltiorrhiza are also discussed. PMID:17302964

Background. The aim of this prospectively collected, retrospectively analyzed clinical investigation was to describe “unmasked” clinical symptoms and methods of diagnosis, treatment, and short-term follow-up of gastroenteropancreatic neuroendocrine tumors (GEP-NETs) diagnosed during 1 year in Austria. Methods. In total, 277 patients with GEP-NETs were documented. All tumors were immunhistochemically defined according to recently summarized criteria (World Health Organization, European Neuroendocrine Tumour Society). A standardized questionnaire comprising 50 clinical and biochemical parameters (clinical symptoms, mode of diagnosis, treatment, follow-up) was completed by attending physicians. Results. The most common initial symptoms were episodes of abdominal pain, diarrhea, weight loss, gastrointestinal bleeding, flushing, and bowel obstruction. Overall, 48.1% of tumors were diagnosed by endoscopy, 43.7% were diagnosed during surgery, 5% were diagnosed by fine-needle aspiration of the primary or metastases, and 2.5% were diagnosed during autopsy; 44.5% of tumors were not suspected clinically and were diagnosed incidentally during various surgical procedures. Overall, 18.7% of tumors were removed endoscopically and 67.6% were removed surgically; 13.7% of patients were followed without interventional treatment. Endoscopic or surgical intervention was curative in 81.4% of patients and palliative in 18.6% of patients. At the time of diagnosis, information on metastasis was available in 83.7% of patients with malignant NETs. Lymph node or distant metastases were documented in 74.7% of patients. In 19.3% of patients, 41 secondary tumors were documented, with 78.0% classified histologically as adenocarcinomas. Conclusion. This investigation summarizes the clinical presentation and current practice of management of GEP-NETs and thereby extends the understanding and clinical experience. PMID:21467149

Data from the United States show that persons from low socioeconomic backgrounds, those who are socially isolated, belong to racial or ethnic minority groups, or identify as lesbian, gay, bisexual, or transgender experience health disparities at a higher rate. Clinicians must transition from a biomedical to a biopsychosocial framework within the clinical examination to better address social determinants of health that contribute to health disparities. We review the characteristics of successful patient-clinician interactions. We describe strategies for relationship-centered care within routine encounters. Our goal is to train clinicians to mitigate differences and reduce disparities in health care delivery. Copyright © 2017 Elsevier Inc. All rights reserved.

Background and Purpose. Contrast media (CM) for magnetic resonance imaging (MRI) may determine the development of acute adverse reactions. Objective was to retrospectively assess the frequency and severity of adverse reactions associated with gadolinium-based contrast agents (GBCAs) injection in patients who underwent MRI. Material and Methods. At our center 10608 MRI examinations with CM were performed using five different GBCAs: Gd-BOPTA (MultiHance), Gd-DTPA (Magnevist), Gd-EOBDTPA (Primovist), Gd-DOTA (Dotarem), and Gd-BTDO3A (Gadovist). Results. 32 acute adverse reactions occurred, accounting for 0.3% of all administration. Twelve reactions were associated with Gd-DOTA injection (0.11%), 9 with Gd-BOPTA injection (0.08%), 6 with Gd-BTDO3A (0.056%), 3 with Gd-EOB-DTPA (0.028%), and 2 with Gd-DTPA (0.018%). Twenty-four reactions (75.0%) were mild, four (12.5%) moderate, and four (12.5%) severe. The most severe reactions were seen associated with use of Gd-BOPTA, with 3 severe reactions in 32 total reactions. Conclusion. Acute adverse reactions are generally rare with the overall adverse reaction rate of 0.3%. The most common adverse reactions were not severe, consisting in skin rash and hives.

Clinical-vignette multiple choice question (MCQ) examinations are used widely in medical education. Standardised MCQ examinations are used by licensure and certification bodies to award credentials that are meant to assure stakeholders as to the quality of physicians. Such uses are based on the interpretation of MCQ examination performance as giving meaningful information about the quality of clinical reasoning. There are several assumptions foundational to these interpretations and uses of standardised MCQ examinations. This study explores the implicit assumption that cognitive processes elicited by clinical-vignette MCQ items are like the processes thought to occur with 'real-world' clinical reasoning as theorised by dual-process theory. Fourteen participants (three medical students, five residents and six staff physicians) completed three sets of five timed MCQ items (total 15) from the Medical Knowledge Self-Assessment Program (MKSAP). Upon answering a set of MCQs, each participant completed a retrospective think aloud (TA) protocol. Using constant comparative analysis (CCA) methods sensitised by dual-process theory, we performed a qualitative thematic analysis. Examinee behaviours fell into three categories: clinical reasoning behaviours, test-taking behaviours and reactions to the MCQ. Consistent with dual-process theory, statements about clinical reasoning behaviours were divided into two sub-categories: analytical reasoning and non-analytical reasoning. Each of these categories included several themes. Our study provides some validity evidence that test-takers' descriptions of their cognitive processes during completion of high-quality clinical-vignette MCQs align with processes expected in real-world clinical reasoning. This supports one of the assumptions important for interpretations of MCQ examination scores as meaningful measures of clinical reasoning. Our observations also suggest that MCQs elicit other cognitive processes, including certain test

The present work was carried out to study the prevalence of Tinea capitis (TC) in Campania over a 9-year period and also to delineate the prevalence of the causative fungus responsible and the clinical forms of tinea capitis. This retrospective study included all the cases of TC occurring between January 2004 and December 2012 to the Mycology Laboratory at the University of Naples "Federico II" and mycologically confirmed. Samples for potassium hydroxide 20% mounts and fungal cultures were collected. Sabouraud dextrose agar were inoculated with the samples. TC was diagnosed by direct microscopy and culture in 143 patients. TC was found to be most common in the group including patients aged between 1-18 years; 13% of patients were over 18 years old. Non-inflammatory clinical forms were the most common type (80.4%). M. canis was the dermatophyte most frequently isolated (64.1%). Microscopic examination revealed an ectothrix pattern of hair invasion to be more common (72% cases). TC was clinical and mycologically diagnosed in 143 patients. It was prevalent in patients aged 1-18 years old; 73.2% of adults affected by TC had possible risk factors and in these patients TC often presented in atypical forms; atypical forms were also observed in children. M. canis was the most common dermatophyte species isolated in children, T. rubrum in adults. We noticed a significant increase of anthropophilic dermatophytes possibly linked to the immigration from African countries. For the diagnosis of TC, mycological examinations are essential.

Objectives This report describes the training of dental examiners participating in two dental caries clinical trials and reports the inter- and intra- examiner reliability scores from the initial standardization sessions. Methods Study examiners were trained to use a modified ICDAS-II system to detect the visual signs of non-cavitated and cavitated dental caries in adult subjects. Dental caries was classified as no caries (S), non-cavitated caries (D1), enamel caries (D2) and dentine caries (D3). Three standardization sessions involving 60 subjects and 3604 tooth surface calls were used to calculate several measures of examiner reliability. Results The prevalence of dental caries observed in the standardization sessions ranged from 1.4% to 13.5% of the coronal tooth surfaces examined. Overall agreement between pairs of examiners ranged from 0.88 to 0.99. An intra-class coefficient threshold of 0.60 was surpassed for all but one examiner. Inter-examiner unweighted kappa values were low (0.23– 0.35) but weighted kappas and the ratio of observed to maximum kappas were more encouraging (0.42– 0.83). The highest kappa values occurred for the S/D1 vs. D2/D3 two-level classification of dental caries, for which seven of the eight examiners achieved observed to maximum kappa values over 0.90.Intra-examiner reliability was notably higher than inter-examiner reliability for all measures and dental caries classification systems employed. Conclusion The methods and results for the initial examiner training and standardization sessions for two large clinical trials are reported. Recommendations for others planning examiner training and standardization sessions are offered. PMID:22320292

The objective structured clinical examination (OSCE) is a widely used method for assessing clinical competence in health sciences education. Studies using this method have shown evidence of validity and reliability. There are no published studies of OSCE reliability measurement with generalizability theory (G-theory) in Latin America. The aims of this study were to assess the reliability of an OSCE in medical students using G-theory and explore its usefulness for quality improvement. An observational cross-sectional study was conducted at National Autonomous University of Mexico (UNAM) Faculty of Medicine in Mexico City. A total of 278 fifth-year medical students were assessed with an 18-station OSCE in a summative end-of-career final examination. There were four exam versions. G-theory with a crossover random effects design was used to identify the main sources of variance. Examiners, standardized patients, and cases were considered as a single facet of analysis. The exam was applied to 278 medical students. The OSCE had a generalizability coefficient of 0.93. The major components of variance were stations, students, and residual error. The sites and the versions of the tests had minimum variance. Our study achieved a G coefficient similar to that found in other reports, which is acceptable for summative tests. G-theory allows the estimation of the magnitude of multiple sources of error and helps decision makers to determine the number of stations, test versions, and examiners needed to obtain reliable measurements.

Examination of clinical and cognitive insight in acute schizophrenia patients.

Greenberger, Cheryl; Serper, Mark R

Lack of insight or awareness of illness is a hallmark feature of schizophrenic illness and has become an increasingly important area of investigation. Although clinical insight focuses on awareness of illness factors, the concept of cognitive insight focuses on the cognitive processes involved in correcting erroneous judgments and certainty about mistaken judgments. The present study was aimed at further investigating the clinical utility and the statistical coherence of the Beck Cognitive Insight Scale (BCIS) (Beck et al., 2004) in acute schizoaffective and schizophrenia (SZ) patients. The present study examined the internal consistency of the scale, as well as its discriminative and predictive validity relative to a well-established traditional measure of clinical insight in a sample of 50 DSM-IV diagnosed SZ patients, presenting for acute inpatient treatment. The BCIS was found to be an internally consistent and a coherent measure of cognitive insight. The BCIS was unassociated with clinical insight, indicating the 2 constructs share little empirical overlap. Cognitive insight was found to be inversely associated with patients' severity of autistic preoccupation symptoms such that those individuals with more cognitive insight, exhibited fewer autistic/cognitive symptoms. Patients' clinical insight, however, was found to be inversely associated specifically with patients' severity of depression. Additionally, clinical insight was also found to be more impaired in patients residing in nursing home environments relative to their counterparts living in less restrictive settings when outside the hospital. Results are discussed in terms of the relationship between clinical and cognitive insight constructs to SZ symptom domains.

To evaluate the interobserver agreement between physicians regarding a abnormal cardiovascular assessment on athletic preparticipation examinations. Cross-sectional clinical survey. Outpatient Clinic, United States Military Academy, West Point, NY. We randomly selected 101 out of 539 cadet-athletes presenting for a preparticipation examination. Two primary care sports medicine fellows and a cardiologist examined the cadets. After obtaining informed consent from all participants, all 3 physicians separately evaluated all 101 cadets. The physicians recorded their clinical findings and whether they thought further cardiovascular evaluation (echocardiography) was indicated. Rate of referral for further cardiovascular evaluation, clinical agreement between sports medicine fellows, and clinical agreement between sports medicine fellows and the cardiologist. Each fellow referred 6 of the 101 evaluated cadets (5.9%). The cardiologist referred none. Although each fellow referred 6 cadets, only 1 cadet was referred by both. The kappa statistic for clinical agreement between fellows is 0.114 (95% CI, -0.182 to 0.411). There was no clinical agreement between the fellows and the cardiologist. This pilot study reveals a low level of agreement between physicians regarding which athletes with an abnormal examination deserved further testing. It challenges the standard of care and questions whether there is a need for improved technologies or improved training in cardiovascular clinical assessment.

To determine the impact of the European Union's Clinical Trials Directive on the number of academic drug trials carried out in Denmark. Retrospective review of applications for drug trials to the Danish Medicines Agency, 1993-2006. Applications for drug trials for alternate years were classified as academic or commercial trials. A random subset of academic trials was reviewed for number of participants in and intended monitoring of the trials. Academic and commercial drug trials showed an identical steady decline from 1993 to 2006 and no noticeable change after 2004 when good clinical practice became mandatory for academic trials. The Clinical Trials Directive introduced in May 2004 to ensure good clinical practice for academic drug trials was not associated with a decline in research activity in Denmark; presumably because good clinical practice units had already been in place in Danish universities since 1999. With such an infrastructure academic researchers can do drug trials under the same regulations as drug companies.

Alzheimer's disease (AD) is one of the most important diseases in an aging society, but the clinical effects of rivastigmine have not been fully examined in real world domestic clinics. We performed the "Okayama Rivastigmine Study (ORS)" to retrospectively analyze the clinical effects of rivastigmine (n = 75) or donepezil (n = 71) on AD patients with seven dementia assessment batteries at the baseline, 3, 6, and 12 months. In addition, we divided the rivastigmine group into two subgroups at the baseline: the mild behavioral and psychological symptoms of dementia (BPSD) group (Abe's BPSD score (ABS) <6) and the severe BPSD group (6≤ABS). In these two subgroups, baseline scores and changes were also retrospectively analyzed until 12 months. Rivastigmine significantly improved the Mini-Mental State Examination score at 3 months (*p <  0.05 versus baseline) and at 6 months (*p <  0.05), the Frontal Assessment Battery (FAB) at 6 months (*p <  0.05), and ABS at 3 months (**p <  0.01) while donepezil only stabilized the three cognitive scores. On the other hand, the Geriatric Depression Scale and the Apathy Scale were stable until 12 months in both groups. Baseline BPSD severity-dependent analysis showed a small improvement of FAB at 6 months in the mild BPSD subgroup (*p <  0.05) and a great improvement of ABS at 3 months in the severe BPSD subgroup (**p <  0.01) in the rivastigmine group. Our present study showed that rivastigmine improved both cognitive and affective functions at 3 and 6 months, and suggested an advantage at 3 and 6 months compared to donepezil in real world dementia clinics.

To better characterize adenomyosis as a disease entity. We retrospectively reviewed the medical records of women undergoing hysterectomy with a histologic diagnosis of adenomyosis, adenomyosis and leiomyomas, and leiomyomas alone. The study included 291 women: 38 with adenomyosis alone, 56 with adenomyosis and leiomyomas, and 197 with leiomyomas alone. In univariate analysis, women with adenomyosis were younger (p = 0.018) and had lower uterine weights (p < 0.001) and more disease-specific symptoms (p = 0.008). In multinomial logistic regression analysis, a lower uterine weight (OR 0.99, CI 95% 0.99-1.0), pelvic pain (OR 4.8, CI 95% 1.5-15.2), a history of smoking (OR 2.6, CI 95% 1.1-6.5) and at least one delivery (OR 4.3, CI 95% 1.5-12.3) were associated with a greater likelihood of having adenomyosis but not leiomyomas alone. Women undergoing hysterectomy with adenomyosis alone have different clinical characteristics from women with adenomyosis and leiomyomas and from those with only leiomyomas.

Infective endocarditis is an uncommon but life-threatening infectious disease. To our knowledge, current investigations of the characteristics of infective endocarditis in our region are scarce. In this study, we aimed to investigate the changes in the epidemiology and clinical features of infective endocarditis. A retrospective analysis of clinical data was performed using 196 infective endocarditis cases diagnosed between June 2004 and December 2012 at The First Affiliated Hospital of China Medical University. A comparative analysis of clinical risk factors was also included. The mean age of the patient cohort was 43.5 (29.0-55.8) years old. Of the 196 cases studied, 128 cases (65.3%) were left native valve infective endocarditis, 13 cases (6.6%) were left prosthetic valve infective endocarditis, and 47 cases (24%) were right valve infective endocarditis. In addition to natural valve endocarditis, many patients also exhibited various types of cardiopathy: 72 cases (36.7%) had congenital cardiovascular malformations, 37 cases (18.9%) had idiopathic mitral valve prolapse and 31 cases (15.8%) had no significant cardiac disease. The primary clinical manifestations that were observed included 168 cases with fever (85.7%), 131 cases with anemia (66.8%), 114 cases with hematuria (58.2%) and 58 cases with splenomegaly (29.6%). Positive blood cultures were detected in 96 cases (49%); the most commonly detected organism was Streptococcus viridans (41 cases; 42.7%), followed by 18 cases (18.8%) of Staphylococcus aureus and 10 cases (10.4%) of Enterococcus. With respect to risk factors, infection with Staphylococcus aureus or gram-negative bacilli (OR = 18.81, 95%CI = 2.39-148.2), congestive heart failure (OR = 8.854, 95%CI = 1.34-54.7), diabetes (OR = 7.224, 95%CI = 1.17-44.7) and age ≥ 60 years (OR = 6.861, 95%CI = 0.94-50.1) were major prognostic risk factors. Infective endocarditis is more common than previously believed, but there are regional

There are limited data to guide clinical management when flat epithelial atypia (FEA) is identified in breast needle core biopsies (NCBs). Our objectives were to determine the frequency of malignancy in subsequent breast excisions following NCB diagnosis of FEA, and to characterize the pathological and clinical features of associated tumors. Two hundred and fifty-six breast NCBs from a retrospective search (January 1999-July 2007) were blindly reviewed for FEA/other columnar cell lesions (CCLs). NCBs with co-existing carcinoma were excluded. The study included 211 NCBs: 116 (55%) with CCLs without atypia; 40 (19%) with CCLs with atypical ductal hyperplasia (ADH), 15 (7%) with FEA and 40 (19%) with FEA and ADH; 94 cases had follow-up excisions. Ductal carcinoma in situ and/or invasive carcinoma were present in: 4/26 (15%) excisions with CCLs on NCB, 11/30 (37%) with CCLs + ADH, 1/7 (14%) with FEA alone, and 9/31 (29%) with FEA + ADH. (a) FEA was more frequently seen with ADH, than without ADH in NCBs, (b) FEA and CCLs were more frequently associated with malignancy when with ADH, and (c) tumors excised following NCB diagnosis of FEA+/-ADH had favorable prognostic factors. A conservative excision is warranted following a NCB diagnosis of FEA and ADH, and may be warranted for FEA alone.

Context: Why some individuals with ankle sprains develop functional ankle instability and others do not (ie, copers) is unknown. Current understanding of the clinical profile of copers is limited. Objective: To contrast individuals with functional ankle instability (FAI), copers, and uninjured individuals on both self-reported variables and clinical examination findings. Design: Cross-sectional study. Setting: Sports medicine research laboratory. Patients or Other Participants: Participants consisted of 23 individuals with a history of 1 or more ankle sprains and at least 2 episodes of giving way in the past year (FAI: Cumberland Ankle Instability Tool [CAIT] score = 20.52 ± 2.94, episodes of giving way = 5.8 ± 8.4 per month), 23 individuals with a history of a single ankle sprain and no subsequent episodes of instability (copers: CAIT score = 27.74 ± 1.69), and 23 individuals with no history of ankle sprain and no instability (uninjured: CAIT score = 28.78 ± 1.78). Intervention(s): Self-reported disability was recorded using the CAIT and Foot and Ankle Ability Measure for Activities of Daily Living and for Sports. On clinical examination, ligamentous laxity and tenderness, range of motion (ROM), and pain at end ROM were recorded. Main Outcome Measure(s): Questionnaire scores for the CAIT, Foot and Ankle Ability Measure for Activities of Daily Living and for Sports, ankle inversion and anterior drawer laxity scores, pain with palpation of the lateral ligaments, ankle ROM, and pain at end ROM. Results: Individuals with FAI had greater self-reported disability for all measures (P < .05). On clinical examination, individuals with FAI were more likely to have greater talar tilt laxity, pain with inversion, and limited sagittal-plane ROM than copers (P < .05). Conclusions: Differences in both self-reported disability and clinical examination variables distinguished individuals with FAI from copers at least 1 year after injury. Whether the deficits could be detected

To investigate whether virtual autopsy with postmortem CT (PMCT) improves clinical diagnosis of the immediate cause of death. Retrospective observational cohort study. inhospital and out-of-hospital deaths over the age of 1 year in whom virtual autopsy with PMCT and conventional autopsy were performed. forensic cases, postmortal organ donors and cases with incomplete scanning procedures. Cadavers were examined by virtual autopsy with PMCT prior to conventional autopsy. The clinically determined cause of death was recorded before virtual autopsy and was then adjusted with the findings of virtual autopsy. Using conventional autopsy as reference standard, we investigated the increase in sensitivity for immediate cause of death, type of pathology and anatomical system involved before and after virtual autopsy. Tertiary referral centre. 86 cadavers that underwent conventional and virtual autopsy between July 2012 and June 2016. PMCT consisted of brain, cervical spine and chest-abdomen-pelvis imaging. Conventional autopsy consisted of thoracoabdominal examination with/without brain autopsy. Increase in sensitivity for the immediate cause of death, type of pathology (infection, haemorrhage, perfusion disorder, other or not assigned) and anatomical system (pulmonary, cardiovascular, gastrointestinal, other or not assigned) involved, before and after virtual autopsy. Using PMCT, the sensitivity for immediate cause of death increased with 12% (95% CI 2% to 22%) from 53% (41% to 64%) to 64% (53% to 75%), with 18% (9% to 27%) from 65% (54% to 76%) to 83% (73% to 91%) for type of pathology and with 19% (9% to 30%) from 65% (54% to 76%) to 85% (75% to 92%) for anatomical system. While unenhanced PMCT is an insufficient substitute for conventional autopsy, it can improve diagnosis of cause of death over clinical diagnosis alone and should therefore be considered whenever autopsy is not performed. © Article author(s) (or their employer(s) unless otherwise stated in the text of

Ultrasonographic remission in addition to clinical remission is probably becoming a new target in the treatment of rheumatoid arthritis. The current study aimed to investigate the risk factors of flare in RA patients who achieved both clinical and ultrasonographic remission. RA patients fulfilled both clinical remission and ultrasonographic remissions were retrospectively enrolled in this study. Baseline clinical, laboratory, and ultrasonographic data were collected. Durations of clinical remission before enrollment and medication strategy during follow-up were recorded. Differences between the flare and the non-flare group were analyzed. Risk factors of flare were assessed with univariate and multivariate Cox proportional hazards models. One hundred and twenty-one RA patients were included. Forty-eight patients relapsed during a median follow-up period of 12.3 months. The flare group had higher percentage of females, shorter duration of clinical remission before enrollment, higher baseline ESR and DAS28 (ESR), and lower baseline gray scale score. Univariate Cox regression revealed female, short duration of remission, high DAS28 (ESR), and failure to achieve 2010 ACR/EULAR remission criteria were risk factors of flare. Furthermore, multivariate analysis showed short duration of remission was the only independent risk factor of flare (HR 0.93, 95% CI 0.88-0.98, P = 0.007). One more month in duration of remission led to a reduction in flare of 7.3%. Short duration of remission at baseline could be an independent risk factor of flare in RA patients who achieved both clinical and ultrasonographic remission, which implicates the significance of sustained remission in the prognosis of RA patients.

There were 312 cases of pulmonary tuberculosis; 155 extra-pulmonary; and 21 disseminated. Three-quarters (327/453) were identified in the overseas-born population. Of the remaining 126 cases, 40 were Torres Strait Islander and 19 Aboriginal Australians. Where drug susceptibility was known, two-thirds (247/368) were fully sensitive; 42 mono-resistant; 78 multidrug-resistant; and one extensively drug resistant. Rates of HIV co-infection were less than three percent (10/362). Tuberculosis remains a significant problem in FNQ. Case numbers have increased three-fold since the 1990s. Much of the increase comes from the overseas-born population. Although PNG accounts for the majority, the number of positive notifications amongst those born elsewhere abroad has increased five-fold since 2010. Tuberculosis amongst Aboriginal Australians has decreased following policy changes in response previous audits. Tuberculosis in Torres Strait residents, however, has increased from 12 cases (1993-2002) to 40 (2006-2016). This article is protected by copyright. All rights reserved.

We performed a retrospective clinical and radiographic evaluation of 83 nonconsecutive patients operated in our institute between February 1996 and March 2003 with a mean follow-up of 60 months to assess the efficiency of unicompartmental knee replacement (UKR) performed with a minimally invasive technique. The aim of this study was to correlate the clinical outcome with the pre- and post-operative alignment and with implant positioning on coronal and sagittal plane. Eighty-three nonconsecutive patients (60 males, 23 females) underwent cemented UKR (De Puy Preservation Uni with all-poly tibial component), for both medial OA (80 patients) and AVN of the medial femoral condyle (3 patients). All patients were available at final follow-up evaluation, and they all presented an evident varus alignment at pre-operative clinical and radiographic evaluation. At radiographic measurement, we considered a knee with femoro-tibial angle (FTA) > 175 degrees as varus knee, 170 degrees < FTA < 175 degrees as normal knee and a knee with a FTA < 170 degrees as a valgus knee. Moreover, we considered a tibial plateau angle (TPA) > 90 degrees for valgus knee and a TPA < 90 degrees for varus knee. According to Hospital for Special Surgery (HSS) scoring system, at a mean follow-up of 60 months, 61 (74%) cases were excellent (100-85 points), 15 (18%) cases were good (84-70 points) and 7 cases (8%) had fair results (<70 points). In our series, patients with an excellent clinical result presented a mean varus deformity of 7.2 degrees (3.6 degrees-10.8 degrees) pre-operatively. According to literature, we demonstrated that a small amount of undercorrection with a small amount of residual varus deformity of 3 degrees-5 degrees is the goal to be reached in order to avoid both rapid degeneration of the nonreplaced compartment and the premature loosening of the replaced compartment. We performed a mean axial correction of 5 degrees (SD 3.9 degrees), leaving a mean axial varus deformity of 2

The aim of this retrospective study was to investigate whether self-reported allergy to penicillin may contribute to a higher rate of postsurgical infection and implant failure. This retrospective, non-interventional, open cohort study reports on implant survival and infection complications of 5,576 implants placed in private practice by one periodontist, and includes 4,132 implants that were followed for at least 1 year. Logistic regression was applied to examine the relationship between self-reported allergy to penicillin and implant survival, while controlling for potential confounders such as smoking, implant site, bone augmentation, loading protocol, immediate implantation, and bone level at baseline. The cumulative survival rate (CSR) was calculated according to the life table method and the Cox proportional hazard model was fitted to data. Out of 5,106 implants placed in patients taking penicillin it was found that 0.8% failed, while 2.1% failed of the 470 implants placed for patients with self-reported allergy to penicillin (P = .002). Odds of failure for implants placed in penicillin-allergic patients were 3.1 times higher than in non-allergic patients. For immediate implant placement, penicillin-allergic patients had a failure rate 10-times higher than the non-allergic cohort. Timing of implant failure occurring within 6 months following implantation was 80% in the penicillin-allergic group versus 54% in the non-allergic group. From the 48 implant sites showing postoperative infection: penicillin-allergic patients had an infection rate of 3.4% (n = 16/470) versus 0.6% in the non-allergic group (n = 32/5,106) (P < .05). Self-reported penicillin allergy was associated with a higher rate of infection, and primarily affected early implant failure.

Physicians and medical students are generally poor-self assessors. Research suggests that this inaccuracy in self-assessment differs by gender among medical students whereby females underestimate their performance compared to their male counterparts. However, whether this gender difference in self-assessment is observable in low-stakes scenarios remains unclear. Our study's objective was to determine whether self-assessment differed between male and female medical students when compared to peer-assessment in a low-stakes objective structured clinical examination. Thirty-three (15 males, 18 females) third-year students participated in a 5-station mock objective structured clinical examination. Trained fourth-year student examiners scored their performance on a 6-point Likert-type global rating scale. Examinees also scored themselves using the same scale. To examine gender differences in medical students' self-assessment abilities, mean self-assessment global rating scores were compared with peer-assessment global rating scores using an independent samples t test. Overall, female students' self-assessment scores were significantly lower compared to peer-assessment (p < 0.001), whereas no significant difference was found between self- and peer-assessment scores for male examinees (p = 0.228). This study provides further evidence that underestimation in self-assessment among females is observable even in a low-stakes formative objective structured clinical examination facilitated by fellow medical students.

The purpose of this study was to evaluate the clinical, radiographic, and patient-based outcomes of dental implants placed at an undergraduate student dental clinic. A retrospective study was performed to determine the success and survival rates of dental implants placed at the undergraduate dental clinic at Dalhousie University between January 1999 and January 2012. Only patients with a minimum of 1-year follow-up were included. Clinical and radiographic assessments determined implant success and survival rates. Questionnaires recorded patients' satisfaction with esthetics, comfort, and ease of hygiene. Of the 352 patients (n = 591 implants) who received implants over 13 years, 165 patients completed the clinical and radiographic examinations. By the end of the study period, demographic information and implant characteristics were collected for 111 (n = 217 implants; 47.5% in the maxilla, 52.6% in the mandible) of these patients. Of those assessed clinically, 36.4% were males and 63.6% females, with a mean age of 56.1 ± 14.15 years (range, 17 to 86 years) at the time of implant placement. The mean follow-up period was 5.8 years (range, 1 to 13 years). The overall implant success and survival rates were 88.0% and 97.2%, respectively. No observable bone loss was evident in 88.0% of the surviving implants. There were no implant fractures. Most patients (91.2%) were very satisfied with the implant restoration appearance, 88.0% were very comfortable with the implant, 92.6% were very satisfied with their ability to chew, and 84.8% reported easy hygiene maintenance at the implant sites. Implant success and survival in an undergraduate student clinic were comparable to those reported in the literature. It seems that inexperienced students were able to provide restorations that were very satisfying to the patients.

Evaluation of the effect of clinical mastitis (CM) and its treatment outcome on the reproductive performance in crossbred cows retrospectively. Datasets of 835 lactating cows affected with CM during a period of 12 years (2001-2012) were considered for this study. Mastitis treatment related data and reproductive parameters such as days to first detected heat (DTFDH), days to first insemination (DTFI), days open (DO), and number of services per conception (SC) were collected from mastitis treatment and artificial insemination registers, respectively. Data were analyzed by ANOVA using SPSS 20 software. The means were compared with the Duncan's multiple comparison post-hoc test. CM affected cows had significantly (p<0.05) higher DTFDH, DTFI, DO and SC compared to clinically healthy cows. Cows diagnosed with a single episode of CM had significantly (p<0.05) delayed DTFDH while, DO and SC were significantly higher (p<0.05) in cows diagnosed by multiple episodes of CM. SC was significantly (p<0.05) higher in cows diagnosed with both relapse and recurrence. Severe CM affected cows had significantly (p<0.05) altered reproductive parameters. The reproductive parameters were altered to high extent when CM occurred during the breeding period. CM-affected cows had higher DTFDH, DTFI, DO and SC compared to clinically healthy cows. The negative effects of CM on reproduction parameters were higher when CM occurred during the breeding period.

Mondor's disease is a rare benign clinical entity characterized by thrombophlebitis of the superficial veins of the anterolateral thoraco-abdominal wall. Although several predisposing factors have been reported, the exact pathogenesis remains unclear. We retrospectively reviewed the medical records of all patients older than 14 years who were diagnosed with Mondor's disease of the breast at the Breast Cancer Surgery Unit of Army General Hospital over a 3-year period. Five cases of Mondor's disease were identified among 5717 breast examinations performed during the study period. In 4 patients the disease was considered to be idiopathic. Ultrasonography established the diagnosis in all patients but mammography was inconclusive in two cases due to the presence of dense breast tissue. Four patients received symptomatic treatment. All patients had complete clinical resolution within 2-8 weeks of presentation, and they are well without any evidence of recurrence for 3 to 32 months later. No cases were associated with breast cancer. Mondor's disease of the breast is a rare benign self-limiting clinical entity. Ultrasonography is the diagnostic modality of choice but mammography may be inconclusive in the presence of dense breast tissue. Awareness of this rare entity is mandatory to prevent an unnecessary biopsy whereas the patients should be reassured of the benign nature of this disorder. Thorough evaluation is however necessary to rule out an underlying breast cancer or another systemic disease.

The comparison of grey-scale ultrasonic and clinical features of hepatoblastoma and hepatocellular carcinoma in children: a retrospective study for ten years

PubMed Central

2011-01-01

Background Hepatoblastoma (HBL) and hepatocellular carcinoma (HCC) are respectively the first and the second most common pediatric malignant liver tumors. The purpose of this study was to evaluate the combined use of the ultrasound examination and the assessment of the patients' clinical features for differentiating HBL from HCC in children. Methods Thirty cases of the confirmed HBL and 12 cases of the confirmed HCC in children under the age of 15 years were enrolled into our study. They were divided into the HBL group and the HCC group according to the histological types of the tumors. The ultrasonic features and the clinical manifestations of the two groups were retrospectively analyzed, with an emphasis on the following parameters: onset age, gender (male/female) ratio, positive epatitis-B-surface-antigen (HBV), alpha-fetoprotein increase, and echo features including septa, calcification and liquefaction within the tumors. Results Compared with the children with HCC, the children with HBL had a significantly younger onset age (8.2 years vs. 3.9 years, P < 0.001) and a significantly smaller frequency of positive HBV (66.7% vs. 13.3%, P < 0.001). The septa and liquefaction were more frequently found in HBL than in HCC (25/30, 83.3% vs. 2/12, 16.7%, P < 0.001; 17/30, 56.7% vs. 3/12, 25%, P = 0.02). When a combination of the liquefaction, septa, negative HBV and onset age smaller than 5 years was used in the evaluation, the sensitivity was raised to 90%, the accuracy was raised to 88%, and the negative predictive value was raised to 73%. Conclusion Ultrasonic features combined with clinical manifestations are valuable for differentiating HBL from HCC in children. PMID:21702993

Testosterone undecanoate depot (TUD) administered intramuscularly is an effective form of testosterone replacement therapy (TRT) for male hypogonadism. Because of the ease of administration, TUD therapy may be preferable to subcutaneously implanted extended release T pellet implants (TI). The primary objective was to retrospectively assess the efficacy and safety of long-term (≥ 2 years therapy) TUD therapy in the clinical setting. The secondary objective was to retrospectively compare TUD with TI therapy. Retrospective data were collected from the Waikato Hospital Endocrine Database for 179 hypogonadal men treated with TUD for ≥ 2 years from 1998-2011, with 124 of these men receiving previous TI therapy. The main outcome measure for efficacy was serum trough total testosterone (TT), and for safety an increase in hemoglobin (Hb) and/or hematocrit (Hct), rise in prostate-specific antigen (PSA) and/or prostatic biopsy and alteration in body mass index and lipid profile. Additional outcome measures were changes in the dosing and/or interval regimens for TUD therapy. Overall, 72% of trough TT levels were in the normal range for TUD therapy compared with 53% of trough TT levels during TI therapy. TUD therapy was well tolerated with 162 men (90.5%) completing 2 years of treatment, and only seven men (3.9%) stopping TUD because of adverse effects. A rise in Hb and/or Hct occurred in 25 men (14%), and a significant rise in PSA in 20 men (13%) at some stage during TUD therapy. At 2 years, 91% of men received the standard 1,000 mg TUD dose with 66% at the standard dosing interval of 10-14 weekly. TUD is an efficacious, safe, and well tolerated form of TRT, and individual optimisation of the dose and/or interval is only required in the minority of men. Particularly given the ease of administration, TUD was the preferred TRT for both patients and clinicians. © 2013 International Society for Sexual Medicine.

Intercomparison of retrospective radon detectors.

1999-01-01

We performed both a laboratory and a field intercomparison of two novel glass-based retrospective radon detectors previously used in major radon case-control studies performed in Missouri and Iowa. The new detectors estimate retrospective residential radon exposure from the accumulation of a long-lived radon decay product, (210)Pb, in glass. The detectors use track registration material in direct contact with glass surfaces to measure the alpha-emission of a (210)Pb-decay product, (210)Po. The detector's track density generation rate (tracks per square centimeter per hour) is proportional to the surface alpha-activity. In the absence of other strong sources of alpha-emission in the glass, the implanted surface alpha-activity should be proportional to the accumulated (210)Po, and hence to the cumulative radon gas exposure. The goals of the intercomparison were to a) perform collocated measurements using two different glass-based retrospective radon detectors in a controlled laboratory environment to compare their relative response to implanted polonium in the absence of environmental variation, b) perform collocated measurements using two different retrospective radon progeny detectors in a variety of residential settings to compare their detection of glass-implanted polonium activities, and c) examine the correlation between track density rates and contemporary radon gas concentrations. The laboratory results suggested that the materials and methods used by the studies produced similar track densities in detectors exposed to the same implanted (210)Po activity. The field phase of the intercomparison found excellent agreement between the track density rates for the two types of retrospective detectors. The correlation between the track density rates and direct contemporary radon concentration measurements was relatively high, considering that no adjustments were performed to account for either the residential depositional environment or glass surface type

The purpose of this quality improvement initiative was to improve the consistency with which radiologists are provided a complete clinical history when interpreting radiography examinations performed in the outpatient and emergency department settings. The clinical history was considered complete if it contained three elements: nature of the symptoms, description of injury, or cause for clinical concern; duration of symptoms or time of injury; and focal site of pain or abnormality, if applicable. This was reduced to three elements: "what-when-where." A goal was established that 95% of the clinical histories should contain all three elements. To achieve this goal, technologists supplemented referring clinicians' history. The project was divided into four phases: launch, support, transition to sustainability, and maintenance. During the support phase, results of automated weekly audits automatically populated group-level performance reports. During the transition to the sustainability phase, audit results populated individual-level performance reports. During the maintenance phase, quarterly audit results were incorporated into technologists' employee performance goals. Before initiation of the project, 38% (76/200) of radiography examinations were accompanied by a complete clinical history. This increased to 92% (928/1006) by the end of the 15-week improvement phase. Performance was sustained at 96% (1168/1213) 7 months later [corrected]. By clearly defining expectations for an appropriate clinical history and establishing system and organizational mechanisms to facilitate verifiable compliance, we were able to successfully and sustainably improve the consistency with which radiography examinations were accompanied by a complete clinical history.

Cognitive performance of patients with chronic heart failure on sacubitril/valsartan : A retrospective cohort study.

PubMed

De Vecchis, R; Ariano, C; Di Biase, G; Noutsias, M

2018-02-15

Sacubitril, a neprilysin inhibitor in the combination molecule sacubitril/valsartan, slows down degradation of endogenous natriuretic peptides, thereby enhancing their beneficial cardiovascular effects. However, sacubitril might also promote neuronal dysfunction and cognitive impairment in patients with chronic heart failure (CHF) treated with sacubitril/valsartan, due to possible neprilysin inhibition at the level of Central Nervous System. A retrospective cohort study was undertaken to detect the effects exerted by sacubitril/valsartan on cognitive function in CHF patients. The patients' clinical data were examined for information provided in the Mini-Mental State Examination (MMSE), which was routinely administered during clinical visits at two centers from 15 March to 31 October 2017. Patients in the sacubitril/valsartan group had a clinical history of at least 3 months of continuous sacubitril/valsartan administration. The control group comprised CHF patients on conventional therapy not taking sacubitril/valsartan. In the between-group comparison, patients were matched for mean age, educational level, sex, NYHA class, and comorbidities. In the present retrospective study only patients in NYHA class II-III were enrolled. The mean MMSE score was 22.72 ± 2.68 (mean ± standard deviation [SD]) in the sacubitril/valsartan group (n = 51 patients) vs. 21.96 ± 2.73 (mean ± SD) in the control group (n = 51; p = 0.1572, independent samples t-test). Thus, a similar mild-to-moderate impairment in cognitive performance was found in the comparison between the two groups. In our study, we did not find any evidence of the alleged harmful influence of sacubitril/valsartan on cognitive function. Patients taking sacubitril/valsartan for at least 3 months had similar mean MMSE scores to control subjects.

Management of pneumonia in many low-income and middle-income countries is based on WHO guidelines that classify children according to clinical signs that define thresholds of risk. We aimed to establish whether some children categorised as eligible for outpatient treatment might have a risk of death warranting their treatment in hospital. We did a retrospective cohort study of children aged 2-59 months admitted to one of 14 hospitals in Kenya with pneumonia between March 1, 2014, and Feb 29, 2016, before revised WHO pneumonia guidelines were adopted in the country. We modelled associations with inpatient mortality using logistic regression and calculated absolute risks of mortality for presenting clinical features among children who would, as part of revised WHO pneumonia guidelines, be eligible for outpatient treatment (non-severe pneumonia). We assessed 16 162 children who were admitted to hospital in this period. 832 (5%) of 16 031 children died. Among groups defined according to new WHO guidelines, 321 (3%) of 11 788 patients with non-severe pneumonia died compared with 488 (14%) of 3434 patients with severe pneumonia. Three characteristics were strongly associated with death of children retrospectively classified as having non-severe pneumonia: severe pallor (adjusted risk ratio 5·9, 95% CI 5·1-6·8), mild to moderate pallor (3·4, 3·0-3·8), and weight-for-age Z score (WAZ) less than -3 SD (3·8, 3·4-4·3). Additional factors that were independently associated with death were: WAZ less than -2 to -3 SD, age younger than 12 months, lower chest wall indrawing, respiratory rate of 70 breaths per min or more, female sex, admission to hospital in a malaria endemic region, moderate dehydration, and an axillary temperature of 39°C or more. In settings of high mortality, WAZ less than -3 SD or any degree of pallor among children with non-severe pneumonia was associated with a clinically important risk of death. Our data suggest that admission to hospital

The majority of hearing loss due to mumps presents as unilateral profound sensorineural hearing loss, which is refractory to treatment. In rare cases of bilateral total deafness, cochlear implants were beneficial for speech perception. Vaccination against mumps is recommended to prevent mumps-associated hearing loss. The objective of this study is to investigate the clinical characteristics of hearing loss due to mumps and to evaluate hearing outcomes. The clinical parameters were analyzed under a retrospective multi-institutional study design in patients diagnosed with hearing loss due to mumps at the Otolaryngology departments of 19 hospitals between 1987 and 2016. Sixty-seven patients with hearing loss due to mumps were enrolled. The study population consisted of 35 males and 32 females, ranging in age from 1 to 54, with a median age of 9.5 years. Sixty-three patients presented with unilateral, and 4 with bilateral hearing loss. Profound hearing loss was observed in 65 ears. Only one ear with severe hearing loss showed complete recovery. Four patients with bilateral hearing loss received cochlear implant surgery. Most of the patients with hearing loss due to mumps had no history of vaccination.

The number of infants with gastroschisis is increasing worldwide, but advances in neonatal intensive care and parenteral nutrition have reduced gastroschisis mortality. Recent clinical data on gastroschisis are often from Western nations. This study aimed to examine clinical features and practice patterns of gastroschisis in Japan. We examined treatment options, outcomes, and discharge status among inpatients with simple gastroschisis (SG) and complex gastroschisis (CG), 2010-2016, using a national inpatient database in Japan. The 247 eligible patients (222 with SG) had average birth weight of 2102 g and average gestational age of 34 weeks; 30% had other congenital anomalies. Digestive anomalies were most common, followed by circulatory anomalies. In-hospital mortality was 8.1%. The median age at start of full enteral feeding was 30 days. The median length of stay was 46 days. There were no significant differences in outcomes except for length of stay, starting full enteral feeding and total hospitalization costs between the SG and CG groups. About 80% of patients were discharged to home without home medical care. The readmission rate was 28%. This study's findings on the clinical characteristics and outcomes of gastroschisis are useful for the clinical management of gastroschisis.

The aim of this study was to investigate the usefulness of postmortem external examination performed by an experienced clinical geneticist as an alternative to autopsy in countries with limited resources. We studied a consecutive cohort of couples seeking genetic counseling for fetal loss or perinatal death over a period of 3 years. The study involved 230 couples; only 57 of them submitted a fetus or dead neonate, for whom a meticulous postmortem clinical examination was performed by an experienced clinical geneticist. The diagnosis rate for the group of cases subjected to postmortem examination (57.9%) was much higher than that of the group that comprised cases for which diagnosis was made through evaluation of medical records (27.2%). Whenever fetal or neonatal autopsy is refused or is not feasible, a comprehensive fetal or perinatal postmortem external examination by an experienced clinical geneticist may be a reasonable substitute.

Complaints in the region of the hips and pelvis are often difficult to classify. This is due to the fact that pain projection and overlapping can occur; therefore, the complete region of the lumbar spine, pelvis and hips must be considered as a single entity in which alterations can result in radiation throughout the whole region. There are many different anatomical structures within the pelvic region so that the function of various muscle components can be impaired and cause pathological alterations to positional relationships of bony structures or even alterations to other soft tissues, such as ligaments, tendons and labra. In terms of differential diagnostics the groin must be seen as the weak point of the peritoneum and vascular system and taken into consideration. Therefore, a detailed and targeted medical history, functional testing and specific examinations and tests are necessary to narrow down the pathology in question and reach a definitive diagnosis. Orthopedic surgeons must know which conspicuous features can lead to which problems and which anatomical structures are likely to be affected by irritation. The results of the clinical examination are the basis for targeted imaging diagnostics and subsequent therapy.

Complaints in the region of the hips and pelvis are often difficult to classify. This is due to the fact that pain projection and overlapping can occur; therefore, the complete region of the lumbar spine, pelvis and hips must be considered as a single entity in which alterations can result in radiation throughout the whole region. There are many different anatomical structures within the pelvic region so that the function of various muscle components can be impaired and cause pathological alterations to positional relationships of bony structures or even alterations to other soft tissues, such as ligaments, tendons and labra. In terms of differential diagnostics the groin must be seen as the weak point of the peritoneum and vascular system and taken into consideration. Therefore, a detailed and targeted medical history, functional testing and specific examinations and tests are necessary to narrow down the pathology in question and reach a definitive diagnosis. Orthopedic surgeons must know which conspicuous features can lead to which problems and which anatomical structures are likely to be affected by irritation.

Objective To examine whether presentation of autism spectrum disorder (ASD) and associated patterns of psychiatric comorbidity and dysfunction vary by referral source. Methods ASD youth referred to a specialized ambulatory program for ASD (N=143) were compared to ASD youth referred to a general child psychiatry clinic (N=217). Results More ASD clinic youth met criteria for a more robust form of ASD (autistic disorder); more youth referred to the psychiatry clinic met criteria for broader spectrum ASD (PDD-NOS). General psychiatry clinic youth with ASD suffered from a greater burden of psychopathologies and higher levels of dysfunction. Conclusion The presentation of ASD in psychiatrically referred youth differs between general and ASD-specialized clinics, though both referral populations have high levels of comorbidity and dysfunction.

Retrospective, multicenter study of robotically-guided spinal implant insertions. Clinical acceptance of the implants was assessed by intraoperative radiograph, and when available, postoperative computed tomography (CT) scans were used to determine placement accuracy. To verify the clinical acceptance and accuracy of robotically-guided spinal implants and compare to those of unguided free-hand procedures. SpineAssist surgical robot has been used to guide implants and guide-wires to predefined locations in the spine. SpineAssist which, to the best of the authors' knowledge, is currently the sole robot providing surgical assistance in positioning tools in the spine, guided over 840 cases in 14 hospitals, between June 2005 and June 2009. Clinical acceptance of 3271 pedicle screws and guide-wires inserted in 635 reported cases was assessed by intraoperative fluoroscopy, where placement accuracy of 646 pedicle screws inserted in 139 patients was measured using postoperative CT scans. Screw placements were found to be clinically acceptable in 98% of the cases when intraoperatively assessed by fluoroscopic images. Measurements derived from postoperative CT scans demonstrated that 98.3% of the screws fell within the safe zone, where 89.3% were completely within the pedicle and 9% breached the pedicle by up to 2 mm. The remaining 1.4% of the screws breached between 2 and 4 mm, while only 2 screws (0.3%) deviated by more than 4 mm from the pedicle wall. Neurologic deficits were observed in 4 cases yet, following revisions, no permanent nerve damage was encountered, in contrast to the 0.6% to 5% of neurologic damage reported in the literature. SpineAssist offers enhanced performance in spinal surgery when compared to free-hand surgeries, by increasing placement accuracy and reducing neurologic risks. In addition, 49% of the cases reported herein used a percutaneous approach, highlighting the contribution of SpineAssist in procedures without anatomic landmarks.

Sensitivity of physical examination versus arthroscopy in diagnosing subscapularis tendon injury.

PubMed

Faruqui, Sami; Wijdicks, Coen; Foad, Abdullah

2014-01-01

The purpose of this study was to examine the accuracy of physical examination in the detection of subscapularis tendon tears and compare it with the gold standard of arthroscopy to determine whether clinical examination can reliably predict the presence of subscapularis tendon tears. This was a retrospective analysis of 52 patients (52 shoulders) who underwent arthroscopic subscapularis tendon repairs between September 2008 and April 2012. Positive findings on any combination of the belly press, lift-off, and bear hug tests constituted a positive physical examination result. There was a positive finding on physical examination in 42 of 52 patients. The sensitivity of the physical examination as a whole was 81%. The literature has shown that the belly press, bear hug, and lift-off tests are specific to the subscapularis tendon. To the authors’ knowledge, this is the first study to evaluate the sensitivity of these 3 separate clinical tests as a composite. Knowledge regarding the sensitivity of the subscapularis-specific physical examination as a composite can lead practitioners to implement all 3 components, even when 1 test has a negative finding, thus promoting a more thorough physical examination. Because unrepaired subscapularis tendon tears can result in poor outcomes in the repair of other rotator cuff tendons, a complete physical examination would be beneficial to patients with shoulder pathology. The authors conclude that physical examination, when performed consistently by an experienced practitioner, can reliably predict the presence of subscapularis tendon tears.

Shoulder pain and disability pose a diagnostic challenge for clinicians owing to the numerous causes that exist. Unfortunately, the evidence in support of most clinical tests is weak or absent. To determine the diagnostic validity of physical examination maneuvers for rotator cuff lesions. Cohort study (diagnosis); Level of evidence, 1. Consecutive shoulder patients recruited for this study were referred to 2 tertiary orthopaedic clinics. A surgeon took a thorough history and indicated his or her certainty about each possible diagnosis. A clinician performed the physical examination for diagnoses where uncertainty remained. Arthroscopy was considered the reference standard for patients who underwent surgery, and MRI with arthrogram was considered the reference for patients who did not. The sensitivity, specificity, and likelihood ratios were calculated to investigate whether combinations of the top tests provided stronger predictions of the presence or absence of disease. There were 139 participants. None of the tests were highly sensitive for diagnosing rotator cuff tears or tendinosis. Tests for subscapularis tears were all highly specific. No optimal combination of tests improved the ability to correctly diagnose rotator cuff tears. Closer analysis revealed the internal rotation and lateral rotation lag sign did not improve the ability to diagnose subscapularis or supraspinatus tears, respectively, although the lateral rotation lag sign demonstrated a discriminatory ability for tear size. No test in isolation is sufficient to diagnose a patient with rotator cuff damage. A combination of tests improves the ability to diagnose damage to the rotator cuff. It is recommended that the internal rotation and lateral rotation lag signs be removed from the gamut of physical examination tests for supraspinatus and subscapularis tears. © 2014 The Author(s).

Physician and patient characteristics associated with clinical inertia in blood pressure control.

Clinical inertia, the failure to adjust antihypertensive medications during patient visits with uncontrolled hypertension, is thought to be a common problem. This retrospective study used 5 years of electronic medical records from a multispecialty group practice to examine the association between physician and patient characteristics and clinical inertia. Hierarchical linear models (HLMs) were used to examine (1) differences in physician and patient characteristics among patients with and without clinical inertia, and (2) the association between clinical inertia and future uncontrolled hypertension. Overall, 66% of patients experienced clinical inertia. Clinical inertia was associated with one physician characteristic, patient volume (odds ratio [OR]=0.998). However, clinical inertia was associated with multiple patient characteristics, including patient age (OR=1.021), commercial insurance (OR=0.804), and obesity (OR=1.805). Finally, patients with clinical inertia had 2.9 times the odds of uncontrolled hypertension at their final visit in the study period. These findings may aid the design of interventions to reduce clinical inertia. ©2013 Wiley Periodicals, Inc.

Structured examination routines have been developed as educational resources for musculoskeletal clinical skills teaching, including Gait-Arms-Legs-Spine (GALS), Regional Examination of the Musculoskeletal System (REMS) and paediatric GALS (pGALS). In this study, we aimed to assess the awareness and use of these examination routines in undergraduate medical teaching in UK medical schools and UK postgraduate clinical practice. Electronic questionnaires were distributed to adult and paediatric musculoskeletal teaching leads at UK medical schools and current UK doctors in training. Responses were received from 67 tutors representing teaching at 22/33 [67 %] of all UK medical schools, and 70 trainee doctors across a range of postgraduate training specialities. There was widespread adoption, at responding medical schools, of the adult examination routines within musculoskeletal teaching (GALS: 14/16 [88 %]; REMS: 12/16 [75 %]) and assessment (GALS: 13/16 [81 %]; REMS: 12/16 [75 %]). More trainees were aware of GALS (64/70 [91 %]) than REMS (14/67 [21 %]). Of the 39 trainees who used GALS in their clinical practice, 35/39 [90 %] reported that it had improved their confidence in musculoskeletal examination. Of the 17/22 responding medical schools that included paediatric musculoskeletal examination within their curricula, 15/17 [88 %] used the pGALS approach and this was included within student assessment at 4 medical schools. We demonstrate the widespread adoption of these examination routines in undergraduate education and significant uptake in postgraduate clinical practice. Further study is required to understand their impact upon clinical performance.

Objective evaluation of distance-based family nurse practitioner (FNP) students can be challenging. One FNP program piloted a teaching innovation, the video-enhanced objective structured clinical examination (VE-OSCE) or "flip" of the traditional face-to-face OSCE, to assess student clinical performance in a controlled online environment using a teleconferencing platform. This project sought to assess the VE-OSCE design, implementation, and ability to identify FNP student learning needs.

Assessment of examiner leniency and stringency ('hawk-dove effect') in the MRCP(UK) clinical examination (PACES) using multi-facet Rasch modelling

McManus, IC; Thompson, M; Mollon, J

2006-01-01

Background A potential problem of clinical examinations is known as the hawk-dove problem, some examiners being more stringent and requiring a higher performance than other examiners who are more lenient. Although the problem has been known qualitatively for at least a century, we know of no previous statistical estimation of the size of the effect in a large-scale, high-stakes examination. Here we use FACETS to carry out a multi-facet Rasch modelling of the paired judgements made by examiners in the clinical examination (PACES) of MRCP(UK), where identical candidates were assessed in identical situations, allowing calculation of examiner stringency. Methods Data were analysed from the first nine diets of PACES, which were taken between June 2001 and March 2004 by 10,145 candidates. Each candidate was assessed by two examiners on each of seven separate tasks. with the candidates assessed by a total of 1,259 examiners, resulting in a total of 142,030 marks. Examiner demographics were described in terms of age, sex, ethnicity, and total number of candidates examined. Results FACETS suggested that about 87% of main effect variance was due to candidate differences, 1% due to station differences, and 12% due to differences between examiners in leniency-stringency. Multiple regression suggested that greater examiner stringency was associated with greater examiner experience and being from an ethnic minority. Male and female examiners showed no overall difference in stringency. Examination scores were adjusted for examiner stringency and it was shown that for the present pass mark, the outcome for 95.9% of candidates would be unchanged using adjusted marks, whereas 2.6% of candidates would have passed, even though they had failed on the basis of raw marks, and 1.5% of candidates would have failed, despite passing on the basis of raw marks. Conclusion Examiners do differ in their leniency or stringency, and the effect can be estimated using Rasch modelling. The reasons for

Aim: Evaluation of the effect of clinical mastitis (CM) and its treatment outcome on the reproductive performance in crossbred cows retrospectively. Materials and Methods: Datasets of 835 lactating cows affected with CM during a period of 12 years (2001-2012) were considered for this study. Mastitis treatment related data and reproductive parameters such as days to first detected heat (DTFDH), days to first insemination (DTFI), days open (DO), and number of services per conception (SC) were collected from mastitis treatment and artificial insemination registers, respectively. Data were analyzed by ANOVA using SPSS 20 software. The means were compared with the Duncan’s multiple comparison post-hoc test. Results: CM affected cows had significantly (p<0.05) higher DTFDH, DTFI, DO and SC compared to clinically healthy cows. Cows diagnosed with a single episode of CM had significantly (p<0.05) delayed DTFDH while, DO and SC were significantly higher (p<0.05) in cows diagnosed by multiple episodes of CM. SC was significantly (p<0.05) higher in cows diagnosed with both relapse and recurrence. Severe CM affected cows had significantly (p<0.05) altered reproductive parameters. The reproductive parameters were altered to high extent when CM occurred during the breeding period. Conclusion: CM-affected cows had higher DTFDH, DTFI, DO and SC compared to clinically healthy cows. The negative effects of CM on reproduction parameters were higher when CM occurred during the breeding period. PMID:28620250

Healthcare workers (HCWs) are at risk of developing occupational skin disease (OSD). To ascertain the causes of OSD in Australian HCWs in a tertiary referral clinic. A retrospective review was performed of patients assessed at the Occupational Dermatology Clinic in Melbourne from 1993 to 2014. Of 685 HCWs assessed in the clinic over a period of 22 years, 555 (81.0%) were diagnosed with OSD. The most common diagnosis was irritant contact dermatitis (ICD) (79.1%), followed by allergic contact dermatitis (ACD) (49.7%). Natural rubber latex allergy was also relatively frequent (13.0%). The major substances causing ACD were rubber glove chemicals (thiuram mix and tetraethylthiuram disulfide), preservatives (formaldehyde, formaldehyde releasers, and isothiazolinones), excipients in hand cleansers, which are hard-to-avoid weak allergens, and antiseptics. ACD caused by commercial hand cleansers occurred more frequently than ACD caused by alcohol-based hand rubs (ABHRs). Occupational ICD was mostly caused by water/wet work and hand cleansers, and environmental irritants such as heat and sweating. Understanding the causes of OSD in HCWs is important in order to develop strategies for prevention. We suggest that skin care advice should be incorporated into hand hygiene education. The use of ABHRs should be encouraged, weak allergens in skin cleansers should be substituted, and accelerator-free gloves should be recommended for HCWs with OSD. © 2016 John Wiley & Sons A/S.

Background. Malaria is a major public health problem in Ethiopia where an estimated 68% of the population lives in malarious areas. Studying its prevalence is necessary to implement effective control measures. Therefore, the aim of this study was to determine seven-year slide positive rate of malaria. Methods. A retrospective study was conducted at Metema Hospital from September 2006 to August 2012. Seven-year malaria cases data had been collected from laboratory registration book. Results. A total of 55,833 patients were examined for malaria; of these, 9486 (17%) study subjects were positive for malaria. The predominant Plasmodium species detected was P. falciparum (8602) (90.7%) followed by P. vivax (852) (9%). A slide positive rate of malaria within the last seven years (2006-2012) was almost constant with slight fluctuation. The age groups of 5-14 years old were highly affected by malariainfection (1375) (20.1%), followed by 15-29 years old (3986) (18.5%). High slide positive rate of malaria occurred during spring (September-November), followed by summer (June-August). Conclusion. Slide positive rate of malaria was high in study area. Therefore, health planners and administrators should give intensive health education for the community.

To evaluate the recurrence rate of gastric dilatation volvulus and the incidence of complications in subsequent coeliotomies following ventral midline gastropexy. The medical records of dogs treated for gastric dilatation volvulus by ventral midline gastropexy were retrospectively reviewed. Owners were contacted and invited to complete a questionnaire and to return to the clinic for ultrasonographic and radiographic follow-up. The questionnaire was completed by 203 owners 2 to 123 months postoperatively, 24 of whom attended the follow-up examination. Of the 203 dogs, 13 (6 · 4%) underwent subsequent ventral midline coeliotomy and none developed complications related to the gastropexy site. In 23 of the 24 re-evaluated dogs, the stomach was closely associated with the abdominal on radiography and/or ultrasound. The recurrence rate for clinical signs of gastric dilatation or gastric dilatation volvulus after ventral midline gastropexy was 6 · 4%. This study shows that the recurrence of gastric dilatation volvulus after ventral midline gastropexy is low and adhesion of the stomach to the abdominal wall is persistent in almost all dogs that were re-examined. The gastropexy site did not appear to interfere with subsequent coeliotomy. © 2015 British Small Animal Veterinary Association.

Objective To assess the effect of ethnicity on student performance in stations assessing communication skills within an objective structured clinical examination. Design Quantitative and qualitative study. Setting A final UK clinical examination consisting of a two day objective structured clinical examination with 22 stations. Participants 82 students from ethnic minorities and 97 white students. Main outcome measures Mean scores for stations (quantitative) and observations made using discourse analysis on selected communication stations (qualitative). Results Mean performance of students from ethnic minorities was significantly lower than that of white students for stations assessing communication skills on days 1 (67.0% (SD 6.8%) and 72.3% (7.6%); P=0.001) and 2 (65.2% (6.6%) and 69.5% (6.3%); P=0.003). No examples of overt discrimination were found in 309 video recordings. Transcriptions showed subtle differences in communication styles in some students from ethnic minorities who performed poorly. Examiners' assumptions about what is good communication may have contributed to differences in grading. Conclusions There was no evidence of explicit discrimination between students from ethnic minorities and white students in the objective structured clinical examination. A small group of male students from ethnic minorities used particularly poorly rated communicative styles, and some subtle problems in assessing communication skills may have introduced bias. Tests need to reflect issues of diversity to ensure that students from ethnic minorities are not disadvantaged.

This study was to explore the relationship between clinical performance examination (CPX) achievement and epistemological beliefs to investigate the potentials of epistemological beliefs in ill-structured medical problem solving tasks. We administered the epistemological beliefs questionnaire (EBQ) to fourth-year medical students and correlated the results with their CPX scores. The EBQ comprised 61 items reflecting five belief systems: certainty of knowledge, source of knowledge, rigidity of learning, ability to learn, and speed of knowledge acquisition. The CPX included scores for history taking, physical examination, and patient-physician interaction. The higher epistemological beliefs group obtained significantly higher scores on the CPX with regard to history taking and patient-physician interaction. The epistemological beliefs scores on certainty of knowledge and source of knowledge were significantly positively correlated with patient-physician interaction. The epistemological beliefs scores for ability to learn were significantly positively correlated with those for history taking, physical examination, and patient-physician interaction. Students with more sophisticated and advanced epistemological beliefs stances used more comprehensive and varied approaches in the patient-physician interaction. Therefore, educational efforts that encourage discussions pertaining to epistemological views should be considered to improve clinical reasoning and problem-solving competence in the clinic setting.

To examine the relationships between measures of attending physician teams' clinical and utilization performance, inpatient hospital audits were conducted in 22 Maryland and western Pennsylvania nonfederal short-term hospitals. A total of 6,980 medical records were abstracted from eight diagnostic categories using the Payne and JCAH PEP medical audit procedures. The results indicate weak statistical associations between the two medical care evaluation audits; between clinical performance and utilization performance, as measured by appropriateness of admissions and length of stay; and between three utilization measures. Based on these findings, it does not appear valid to use performance in one area to evaluate performance in the other in order to measure or evaluate and ultimately improve physicians; clinical or utilization performance.

Part of the psoriasis patients with musculoskeletal complaints will have inflammation of the entheses. Entheseal inflammation is difficult to assess by clinical examination only. Therefore, we aimed to determine the frequency of clinically relevant ultrasound inflammation at the most commonly assessed entheses (MASEI; Madrid Sonographic Enthesis Index) in primary care psoriasis patients with one or more tender entheses. Adult primary care psoriasis patients with musculoskeletal complaints (tender enthesis or arthritis at physical examination) had an ultrasound examination of seven entheses according to the MASEI. Clinically relevant ultrasound inflammation was defined as active inflammation on ultrasound in combination with at least one clinical feature at the same enthesis. Active ultrasound inflammation contained positive power Doppler signal or in case of the plantar aponeurosis increased thickness. Structural changes entailed calcifications, enthesophytes, increased thickness, hypoechogeneicity indicating irregular fibre structure and erosions. Clinically, an enthesis was scored positive by a tender enthesis at clinical examination, reported pain in the history or self-reported pain in the questionnaires. Of 542 primary care psoriasis patient, 111 patients had tender entheses and/or arthritis. These patients were both clinically and ultrasonographically evaluated. Active ultrasound inflammation accompanied with pain or tenderness at the enthesis was found in 36% of the patients (n=40). Most common were inflammation at the knee (n=11) and at the plantar aponeurosis (n=10). Structural changes were observed in 95% of the psoriasis patients independent of their clinical manifestation. We found concurrent presence of ultrasound inflammatory changes and clinical symptoms in 36% of the primary care psoriasis patients who had tenderness at one or more entheseal sites.

We sought to investigate the clinical features of and risk factors for recurrent major depression (MD) with history of postpartum episodes (PPD) in Han Chinese women and the differences between first-onset postpartum MD (MD that has its first lifetime depressive episode in the postpartum period) and first-onset non-postpartum MD (MD with history of PPD and has its first lifetime depressive episode in a period other than postpartum). Data were derived from the China, Oxford and Virginia Commonwealth University Experimental Research on Genetic Epidemiology (CONVERGE) study (N=6017 cases) and analyzed in two steps. We first examined the clinical features of and risk factors for MD patients with (N=981) or without (N=4410) a history of PPD. We then compared the differences between first-onset postpartum MD (N=583) and first-onset non-postpartum MD (N=398) in those with a history of PPD. Linear, logistic and multinomial logistic models were employed to measure the associations. A history of PPD was associated with more guilt feelings, greater psychiatric comorbidity, higher neuroticism, earlier onset and more chronicity (OR 0.2-2.8). Severe premenstrual symptoms (PMS) and more childbirths increased the risk of PPD, as did a family history of MD, childhood sexual abuse, stressful life events and lack of social support (OR 1.1-1.3). In the MD with history of PPD subsample, first-onset postpartum MD was associated with fewer recurrent major depressive episodes, less psychiatric comorbidity, lower neuroticism, less severe PMS and fewer disagreements with their husbands (OR 0.5-0.8), but more childbirths (OR 1.2). Data were obtained retrospectively through interview and recall bias may have affected the results. MD with history of PPD in Han Chinese women is typically chronic and severe, with particular risk factors including severe PMS and more childbirths. First-onset postpartum MD and first-onset non-postpartum MD can be partly differentiated by their clinical features

Clinical characteristics and reproductive outcome following hysteroscopic adhesiolysis of patients with intrauterine adhesion--a retrospective study.

2014-01-01

The authors performed a retrospective clinical analysis of 153 patients with intrauterine ashesion (IUA) who underwent hysteroscopic adhesiolysis. A follow-up office hysteroscopy was performed in all cases after three months. On follow-up hysteroscopy, 22 patients showed reformation of adhesions and required a repeat procedure. The primary risk factor for IUA was uterine curettage associated with pregnancy termination. The follow-up study revealed that the rate of pregnancy after IUA treatment was 51%. The conception rate in women who had reformation of IUA was significantly lower than that of women who had a normal cavity following adhesiolysis. Therefore the authors conclude that prevention is more important than therapy in IUA. Increasing education about avoiding curettage is necessary to reduce the incidence of IUA. Outreach is particularly important for older women with less education. However, hysteroscopic adhesiolysis for IUA is a safe and effective method of choice for restoring menstrual function and fertility.

Using outpatient neurology clinic case logs completed by medical students on neurology clerkships, we examined the impact of outpatient clinical encounter volume per student on outcomes of knowledge assessed by the National Board of Medical Examiners (NBME) Clinical Neurology Subject Examination and clinical skills assessed by the Objective Structured Clinical Examination (OSCE). Data from 394 medical students from July 2008 to June 2012, representing 9,791 patient encounters, were analyzed retrospectively. Pearson correlations were calculated examining the relationship between numbers of cases logged per student and performance on the NBME examination. Similarly, correlations between cases logged and performance on the OSCE, as well as on components of the OSCE (history, physical examination, clinical formulation), were evaluated. There was a correlation between the total number of cases logged per student and NBME examination scores (r = 0.142; p = 0.005) and OSCE scores (r = 0.136; p = 0.007). Total number of cases correlated with the clinical formulation component of the OSCE (r = 0.172; p = 0.001) but not the performance on history or physical examination components. The volume of cases logged by individual students in the outpatient clinic correlates with performance on measures of knowledge and clinical skill. In measurement of clinical skill, seeing a greater volume of patients in the outpatient clinic is related to improved clinical formulation on the OSCE. These findings may affect methods employed in assessment of medical students, residents, and fellows.

The Objective Structured Clinical Examination (OSCE) appears to be an effective alternative for assessing not only medical knowledge, but also clinical skills, including effective communication and physical examination skills. The purpose of the current study was to implement an OSCE model in a geriatrics fellowship program and to compare the instrument with traditional essay examination. Seventy first- and second-year geriatric fellows were initially submitted to a traditional essay examination and scored from 0 to 10 by a faculty member. The same fellows subsequently underwent an OSCE with eight 10-minute stations covering a wide range of essential aspects of geriatric knowledge. Each OSCE station had an examiner responsible for its evaluation according to a predefined checklist. Checklist items were classified for analysis purposes as clinical knowledge items (CKI) and communication skills items (CSI); fellow responses were scored from 0 to 10.Although essay examinations took from 30 to 45 minutes to complete, 180-200 minutes were required to evaluate fellows using the proposed OSCE method. Fellows scored an average of 6.2 ± 1.2 on the traditional essay examination and 6.6 ± 1.0 on the OSCE (P < .001). Subanalyses of OSCE scores indicated that average performance on CKI was lower than the average on CSI (6.4 ± 1.1 vs. 8.4 ± 1.1; P < .001). Fellow performance on the essay examination was similar to their performance on CKI (P = .13). Second-year fellows performed better than first-year fellows on the essay examination (P < .001) and CKI (P = .05), but not on CSI (P = .25).The OSCE was successfully implemented as an educational strategy during a geriatrics fellowship program. Combining different testing modalities may provide the best assessment of competence for various domains of knowledge, skills, and behavior. © 2012, Copyright the Authors Journal compilation © 2012, The American Geriatrics Society.

Objectives To examine the feasibility of detecting adverse events through record review in British hospitals and to make preliminary estimates of the incidence and costs of adverse events. Design Retrospective review of 1014 medical and nursing records. Setting Two acute hospitals in Greater London area. Main outcome measure Number of adverse events. Results 110 (10.8%) patients experienced an adverse event, with an overall rate of adverse events of 11.7% when multiple adverse events were included. About half of these events were judged preventable with ordinary standards of care. A third of adverse events led to moderate or greater disability or death. Conclusions These results suggest that adverse events are a serious source of harm to patients and a large drain on NHS resources. Some are major events; others are frequent, minor events that go unnoticed in routine clinical care but together have massive economic consequences. PMID:11230064

Regular student evaluations at the Technical University Munich indicate the necessity for improvement of the clinical examination course. The aim of this study was to examine if targeted measures to restructure and improve a clinical examination course session lead to a higher level of student satisfaction as well as better self-assessment of the acquired techniques of clinical examination. At three medical departments of the Technical University Munich during the 2010 summer semester, the quantitative results of 49 student evaluations (ratings 1-6, German scholastic grading system) of the clinical examination course were compared for a course before and a course after structured measures for improvement. These measures included structured teaching instructions, handouts and additional material from the Internet. 47 evaluations were completed before and 34 evaluations after the measures for improvement. The measures named above led to a significant improvement of the evaluative ratings in the following areas: short introduction to the topic of each clinical examination course (from 2.4±1.2 to1.7±1.0; p=0.0020) and to basic measures of hygiene (from 3.8±1.9 to 2.5±1.8; p=0.004), structured demonstration of each clinical examination step (from 2.9±1.5 to 1.8±1.0; p=0.001), sufficient practice of each clinical examination step (from 3.1±1.8 to 2.2±1.4; p=0.030) structured feedback on each clinical examination step (from 3.0±1.4 to 2.3±1.0; p=0.0070), use of handouts (from 5.2±1.4 to 1.8±1.4; p<0.001), advice on additional learning material (from 5.0±1.4 to 3.4±2.0; p<0.001), general learning experience (from 2.4±0.9 to 1.9±0.8; p=0.017), and self-assessment of the acquired techniques of clinical examination (from 3.5±1.3 to 2.5±1.1; p<0.01). Structured changes led to significant improvement in the evaluative ratings of a clinical examination course session concerning preparation of the tutors, structure of the course, and confidence in performing

Our aim was to describe the pattern of ventriculostomy-related infection (VRI) development using a dynamic approach. Retrospective longitudinal study. We analyzed the files of 449 neurosurgical patients who underwent placement of external ventricular drain (EVD). During the study period, CSF sampling was performed on a daily base setting. VRI was defined as a positive CSF culture resulting in antibiotic treatment. For VRI patients, we arbitrary defined day 0 (D0) as the day antibiotic treatment was started. In these patients, we compared dynamic changes in clinical and biological parameters at four pre-determined time points: (D-4, D-3, D-2, D-1) with those of D0. For all CSF-positive cultures, we compared CSF biochemical markers' evolution pattern between VRI patients and the others, considered as a control cohort. Thirty-two suffered from VRI. Peripheral white blood cell count did not differ between D-4-D0. Median body temperature, CSF cell count, median Glasgow Coma Scale, CSF protein, and glucose concentrations were significantly different between D-4, D-3, D-2, and D0. At D0, 100 % of CSF samples yielded organisms in culture. The physician caring for the patient decided to treat VRI based upon positive CSF culture in only 28 % (9/32) of cases. In the control cohort, CSF markers' profile trends to normalize, while it worsens in the VRI patients. We showed that clinical symptoms and biological abnormalities of VRI evolved over time. Our data suggest that VRI decision to treat relies upon a bundle of evidence, including dynamic changes in CSF laboratory exams combined with microbiological analysis.

Clinical information is needed to assess the causal relationship between a drug and an adverse drug reaction (ADR) in a reliable way. Little is known about the level of relevant clinical information about the ADRs reported by patients. The aim was to determine to what extent patients report relevant clinical information about an ADR compared with their healthcare professional. A retrospective analysis of all ADR reports on the same case, i.e., cases with a report from both the patient and the patient's healthcare professional, selected from the database of the Dutch Pharmacovigilance Center Lareb, was conducted. The extent to which relevant clinical information was reported was assessed by trained pharmacovigilance assessors, using a structured tool. The following four domains were assessed: ADR, chronology, suspected drug, and patient characteristics. For each domain, the proportion of reported information in relation to information deemed relevant was calculated. An average score of all relevant domains was determined and categorized as poorly (≤45%), moderately (from 46 to 74%) or well (≥75%) reported. Data were analyzed using a paired sample t test and Wilcoxon signed rank test. A total of 197 cases were included. In 107 cases (54.3%), patients and healthcare professionals reported a similar level of clinical information. Statistical analysis demonstrated no overall differences between the groups (p = 0.126). In a unique study of cases of ADRs reported by patients and healthcare professionals, we found that patients report clinical information at a similar level as their healthcare professional. For an optimal pharmacovigilance, both healthcare professionals and patient should be encouraged to report.

Acute phlebitis due to peripheral vein catheter use is frequently observed in clinical practice, and requires surgical therapy in severe cases. In this retrospective study, we aimed to increase awareness, evaluate current treatment options, and develop recommendations to optimize treatment outcomes. A total of 240 hospitalized patients with a diagnosis of upper extremity phlebitis from 2006 to 2011 were evaluated in terms of initial clinical features, parameters, co-morbidities and treatment regimes. Severity of phlebitis was graded according to the Baxter scale by assessing clinical symptoms such as pain, erythema, induration, swelling, or palpable venous cord (grade 0-5). Patients were divided in two subgroups: conservative (n = 132) and operative (n = 108) treatment. Surgical intervention rates and severity were higher for cannula insertion in the cubital fossa region than for cannula insertion in the forearm and hand region (p < 0.05). Baxter scale grades were higher in the surgical treatment group than in the conservative treatment group (4.47 vs. 2.67, respectively). The cubital fossa region is vulnerable to severe phlebitis and is not recommended as the first site of choice for cannulation. Phlebitis of Baxter scale grade 4 or 5 should be considered for early surgical intervention. © The Author(s) 2014.

Evaluation of resident physicians' communications skills is a challenging task and is increasingly accomplished with standardized examinations. There exists a need to identify the effective, efficient methods for assessment of communications skills. We compared objective structured clinical examination (OSCE) and direct observation as approaches for assessing resident communications skills. We conducted a retrospective cohort analysis of orthopaedic surgery resident physicians at a single tertiary care academic institution, using the Institute for Healthcare Communication "4 Es" model for effective communication. Data were collected between 2011 and 2015. A total of 28 residents, each with OSCE and complete direct observation assessment checklists, were included in the analysis. Residents were included if they had 1 OSCE assessment and 2 or more complete direct observation assessments. There were 28 of a possible 59 residents (47%) included. A total of 89% (25 of 28) of residents passed the communications skills OSCE; only 54% (15 of 28) of residents passed the direct observation communications assessment. There was a positive, moderate correlation between OSCE and direct observation scores overall ( r  = 0.415, P  = .028). There was no agreement between OSCE and direct observation in categorizing residents into passing and failing scores (κ = 0.205, P  = .16), after adjusting for chance agreement. Our results suggest that OSCE and direct observation tools provide different insights into resident communications skills (simulation of rare and challenging situations versus real-life daily encounters), and may provide useful perspectives on resident communications skills in different contexts.

The effectiveness of immediate feedback during the objective structured clinical examination.

Using eight different physical examination or technical stations, 400 examinations were conducted to evaluate the effectiveness of immediate feedback during the Objective Structured Clinical Examination (OSCE). The test group comprised 50 medical students who underwent a standard 4-minute examination followed by 2 minutes of feedback. Immediately following feedback the students repeated an identical 4-minute examination scored by the same examiners. The control group consisted of 50 students from the same class who underwent an identical testing sequence, but instead of receiving feedback, they were instructed to continue their examinations for an additional 2 minutes before repeating the stations. Simple repetition of the task did not significantly improve score (mean increase 2.0%, NS). Extending the testing period from 4 to 6 minutes resulted in a small but significant increase in score (mean 6.7%, P less than 0.001). However, there was a much larger increase in the scores obtained following 2 minutes of immediate feedback compared to pre-feedback performance (mean 26.3%, P less than 0.0001). The majority of students and examiners felt that feedback, as administered in this study, was valuable both as a learning and teaching experience. Short periods of immediate feedback during an OSCE are practical and can improve competency in the performance of criterion-based tasks, at least over the short term. In addition, such feedback provides students with valuable self-assessment that may stimulate further learning.

To review the association between clinical signs and diagnostic findings and the survival time of dogs with dilated cardiomyopathy (DCM), and any influence of treatment prescribed. A retrospective observational study of 367 dogs with DCM. Survival times until death or euthanasia for cardiac reasons were analysed using the Kaplan-Meier method plus univariate and multivariate Cox proportional hazards models. Two-tailed P values less than 0.05 were considered statistically significant. In the multivariate model, left ventricular diameter (LVDs)-index (P=0.0067), presence of pulmonary oedema on radiography (P=0.043), presence of ventricular premature complexes (VPCs) (P=0.0012), higher plasma creatinine (P=0.0002), lower plasma protein (P=0.029) and great Dane breed (P=0.0003) were negatively associated with survival. Most dogs were treated with angiotensin-converting enzyme inhibitors (93%) or furosemide (86%), and many received digoxin (50%) and/or pimobendan (30%). Thirteen dogs were lost to follow-up. No conclusions could be made in this study on the association between use of drugs and survival. The LVDs-index was the single best variable for assessing the prognosis in this group of dogs with DCM. Other variables that were negatively associated with survival were presence of pulmonary oedema on radiography, presence of VPCs, higher plasma creatinine, lower plasma protein and great Dane breed.

[Clinical techniques for use in neurological physical examinations. II. Motor and reflex functions].

PubMed

Rodríguez-García, P L; Rodríguez-Pupo, L; Rodríguez-García, D

The aim of this study is to highlight the chief practical aspects of the techniques used in the neurological physical examination of the motor and reflex functions. We recommend clinicians to carry out a brief but consistent and effective exploration in a systematic, flexible and orderly manner to check for abnormalities in the motor and reflex functions of the nervous system. Should any anomalies be detected, then a more detailed and thorough neurological exploration must be performed selectively. We present a detailed review of the practical aspects of the main techniques used in the physical examination of these neurological categories. The motor function is explored using techniques that examine muscle tone, muscle strength, muscle fatigability, hypokinesia, tremor, coordination and gait. Lastly, in this category several manoeuvres that are useful in hysterical or mimicking paralyses are also dealt with. Reflexes to examination are usually divided into: 1. Myotatic reflexes; 2. Cutaneomucous reflexes; 3. Spinal cord or defence automatism reflexes; 4. Posture and attitude reflexes. We also add the study of primitive pathological reflexes, remote reflexes, synkinesias and signs of meningeal irritation. We present a detailed description of the main clinical techniques used in the neurological physical examination of motility and reflexes, as well as an approach that allows them to be performed on adult patients. In addition, we underline the importance of physically examining the nervous system in contemporary medicine and the need to continually perfect the way these techniques are performed in order to achieve an efficient clinical practice.

The aim of this retrospective study was to provide data on the clinical features and treatment outcomes of patients with NDPH (fulfilling Kung et al.'s criteria). A total of 63 patients were observed during a 5-yr period (2007-2012). More than one-third (35 %) patients had migrainous features; 65 % patients fulfilled the ICHD-II criteria. Both groups were similar in most clinical and epidemiological features. However, migrainous features were more common in patients with a prior history of episodic migraine (though statistically not significant). After a median follow-up of 9 months, 37 % patients showed "excellent" response (no or less than 1 headache per month). Another 30 % patients had "good" response (>50 % reduction in headache frequency or days per month). Excellent response was more in patients with a history of less than 6 months duration (statistically not significant). Patients with a recognized trigger showed better prognosis. Response was better in patients who received intravenous therapy of methyl prednisolone and sodium valproate. We suggest prospective and controlled studies to confirm our observations.

Information gathering ability had been evaluated mainly via checklists in clinical performance examinations (CPX). But, it is not proved yet if students write the information correctly in postencounter note (PN), although they asked questions or performed physical examinations (PE) about the information when they interacted with standardized patients in CPX. This study addressed the necessity of introducing PN to evaluate the ability in CPX. After patient encounters, students were instructed to write the findings of history taking and physical examination that they considered as important information in approaching the patient's problems in PN. PNs were scored using answer keys selected from checklist items, which were considered to be recorded in PN by CPX experts. PNs of six CPX cases from 54 students were analyzed. Correlation coefficients between the key-checklist scores and PN scores of six cases were moderate to high (0.52 to 0.79). However, students frequently neglected some cardinal features of chief complains, pertinent findings of past/social history and PE, and pertinent negative findings of associated symptoms in PNs, which were checked as 'done' in the keys of checklists. It is necessary to introduce PN in CPX to evaluate the students' ability of synthesis and integration of patient information.

The aim of this study was to determine the possibility of non-operative treatment via retrospective analysis of our patients. Fifty patients with penetrating hepatic injuries were examined retrospectively with respect to trauma scores, associated injuries, complications, and mortality parameters. Thirteen injuries were caused by firearms, whereas 37 injuries were caused by stab wounds. Forty-three patients (86%) underwent laparotomy and 7 patients (14%) were monitored by CT and clinical findings (nonoperative group, NO group). The laparotomies were evaluated as non-therapeutic in 11 patients (22%) (NTL group) and therapeutic in 32 patients (64%) (TL group). The morbidity and mortality rates were 40 and 10%, respectively. RTS and ISS scores of the nonsurviving and the surviving patients were significantly different. The rates of major venous, grade IV-V hepatic injuries, and gunshot wounds were significantly higher in the nonsurviving patients when compared to the surviving patients. Major venous and grade IV-V hepatic injuries were the primary factors determining mortality and these injuries generally occurred as a result of firearm injuries. NTL occurring at a rate of 22% would decrease to 2% if 'RTS <7' criteria was added to the hemodynamic instability and/or peritoneal irritation findings determining surgical candidacy.

This study aimed to describe the signalment, clinical signs, magnetic resonance imaging (MRI) findings, cerebrospinal fluid (CSF) analysis, treatment, and outcome of feline meningoencephalomyelitis of unknown origin (FMUO). Medical records from 16 cats meeting the inclusion criteria of CSF pleocytosis, negative CSF polymerase chain reaction (PCR)-infectious disease results, and characteristic MRI findings were retrospectively reviewed. Median age was 9.4 years. Clinical signs included ataxia, proprioceptive deficits, seizures, and spinal hyperesthesia. The CSF nucleated cell count was increased (median 70.7 cells/μL), with predominantly mixed pleocytosis and CSF protein concentration was increased in 15/16 cats. Magnetic resonance imaging showed intraparenchymal infiltrative ill-defined lesions in 13 cases. All cats received a corticosteroid-based treatment protocol; additional therapies included lomustine, cytarabine, and anticonvulsant medications. Mild neurological signs were recorded in 5/12 cats but 7/12 cats were neurologically normal at re-examination. This represents the first study of feline MUO, highlighting FMUO as an important differential diagnosis in cats with variable neurological presentation. Prognosis appears to be good with immunomodulatory therapy. PMID:28966357

Although both gender- and sports-specific injuries exist among athletes, gender differences in the types of injuries caused by sports activities, except for anterior cruciate ligament (ACL) injury and anterior knee pain, are not well established. An observational study with a retrospective case-series design was conducted to investigate gender-specific differences in the types of injuries sustained while engaging in sports activities common to both males and females. We analyzed injuries sustained during sports activities including basketball, volleyball, tennis, skiing, track and field, and swimming, using data on age, sex, sports activities, activity levels, and sports injuries that had been computerized at our sports medicine (orthopedics) clinic. Inclusion criteria were sports activities that had a record of >100 injuries in total and athletes aged <50 years who were engaging in only 1 sports activity. We determined the absolute number of patients in each category and their percentage (proportion) of our cohort. The proportions of common injuries caused by sports activities were investigated, and gender-specific differences in the types of common injuries caused by sports activities were clarified. The Fisher exact test was used to determine the significance (P < 0.01) of the gender-specific differences in the types of sports injuries. According to our database, during the 14-year period between October 1992 and December 2006, a total of 2,989 athletes (1,624 males and 1,365 females) aged <50 years who engaged in 1 of the 6 sports activities described consulted our sports medicine clinic. The most common sports injuries were ACL injury (14.3%) and knee pain (13.7%), followed by ankle sprain (9.4%), lumbar disc disease (7.0%), meniscus injury (5.1%), stress fracture (2.9%), low back pain (2.5%), patellar tendinitis (2.1%), injury of the medial collateral ligament of the knee (2.0%), lumbar spondylolysis (1.7%), and muscle strain (1.5%).

The overall median lifespan of domestic dogs has been estimated to 9-12 years, but little is known about risk factors for mortality in aged and a priori healthy dogs. The objective of this retrospective cohort study was to determine which characteristics are associated with mortality in aged and a priori healthy guide dogs, in a retrospective cohort study of 116 guide dogs followed from a systematic geriatric examination at the age of 8-10 years old. A geriatric grid collected the clinical data and usual biological parameters were measured at the time of examination. Univariate (Kaplan-Meier estimates) and multivariable (Cox proportional hazard model) survival analyses were used to assess the associations with time to all-cause death. The majority of dogs were Golden Retrievers (n=48) and Labrador Retrievers (n=27). Median age at geriatric examination was 8.9 years. A total of 76 dogs died during follow-up, leading to a median survival time from geriatric examination of 4.4 years. After adjustment for demographic and biological variables, an increased alanine amionotransferase level (adjusted Hazard Ratio (adjusted HR), 6.2; 95% confidence interval [95%CI], 2.0-19.0; P<0.01), presenting skin nodules (adjusted HR, 1.9; 95% CI, 1.0-3.4; P=0.04), and not being a Labrador Retriever (adjusted HR, 3.3; 95%CI, 1.4-10; P<0.01) were independently associated with a shorter time to death. This study documents independent associations of alanine aminotransferase level, skin nodules and breed with mortality in aged guide dogs. These results may be useful for preventive medical care when conducting a geriatric examination in working dogs. Copyright © 2016 Elsevier B.V. All rights reserved.

Controversy persists as to whether lichen planus pigmentosus and ashy dermatosis are separate clinical entities. This study was conducted to examine the clinicopathological features and treatment outcome of the two conditions. A retrospective medical chart review of all patients who were diagnosed with lichen planus pigmentosus or ashy dermatosis was conducted. The information collected included the participants' age at onset, site of onset, duration of disease, presence of precipitating factors, distribution of disease, pigmentation and presence of symptoms. In patients from whom a biopsy was taken the histopathological reports were included. Altogether 26 patients with ashy dermatosis and 29 with lichen planus pigmentosus were included in the study. Compared with ashy dermatosis, lichen planus pigmentosus had a more localised distribution with a preponderance for facial involvement, compared with the truncal preponderance in ashy dermatosis. Ashy dermatosis tended to have a more stable clinical course than lichen planus pigmentosus, which was more likely to wax and wane. The utility of histopathology in differentiating between the two conditions is low. Ashy dermatosis and lichen planus pigmentosus, as defined in this study, appear to be two separate clinical entities with distinguishable clinical features and natural histories. © 2018 The Australasian College of Dermatologists.

A retrospective cohort and a questionnaire survey were used. The data were analysed thematically. the outcomes of the first 226 women accessing the MNBU were compared with a matched retrospective cohort of 226 women accessing standard care. In total, 128 participants completed a satisfaction questionnaire before discharge. mode of birth and model of care. the vaginal birth rate was 87.6% in the MNBU compared with 58.8% in the standard care unit. All women who accessed the MNBU were supported by both a midwife and a birth companion, referred to as 'two-to-one' care. None of the women labouring in the standard care unit were identified as having a birth companion. the concept of 'two-to-one' care emerged as fundamental to women's experiences and utilisation of midwives' skills to promote normal birth and decrease the likelihood of a caesarean section. the MNBU provides an environment where midwives can practice to the full extent of their role. The high vaginal birth rate in the MNBU indicates the potential of this model of care to reduce obstetric intervention and increase women's satisfaction with care within a context of extraordinary high caesarean section rates. midwife-led care implies a separation of obstetric care from maternity care, which has been advocated in many European countries.

Summary Background Few studies have reported long-term data on mortality rates for children admitted to hospital with pneumonia in Africa. We examined trends in case fatality rates for all-cause clinical pneumonia and its risk factors in Malawian children between 2001 and 2012. Methods Individual patient data for children (<5 years) with clinical pneumonia who were admitted to hospitals participating in Malawi’s Child Lung Health Programme between 2001 and 2012 were recorded prospectively on a standardised medical form. We analysed trends in pneumonia mortality and children’s clinical characteristics, and we estimated the association of risk factors with case fatality for children younger than 2 months, 2–11 months of age, and 12–59 months of age using separate multivariable mixed effects logistic regression models. Findings Between November, 2012, and May, 2013, we retrospectively collected all available hard copies of yellow forms from 40 of 41 participating hospitals. We examined 113 154 pneumonia cases, 104 932 (92.7%) of whom had mortality data and 6903 of whom died, and calculated an overall case fatality rate of 6.6% (95% CI 6.4–6.7). The case fatality rate significantly decreased between 2001 (15.2% [13.4–17.1]) and 2012 (4.5% [4.1–4.9]; ptrend<0.0001). Univariable analyses indicated that the decrease in case fatality rate was consistent across most subgroups. In multivariable analyses, the risk factors significantly associated with increased odds of mortality were female sex, young age, very severe pneumonia, clinically suspected Pneumocystis jirovecii infection, moderate or severe underweight, severe acute malnutrition, disease duration of more than 21 days, and referral from a health centre. Increasing year between 2001 and 2012 and increasing age (in months) were associated with reduced odds of mortality. Fast breathing was associated with reduced odds of mortality in children 2–11 months of age. However, case fatality rate in 2012

Rapid diagnosis of GAS pharyngitis may improve patient care by ensuring that patients with GAS pharyngitis are treated quickly and also avoiding unnecessary use of antibiotics in those without GAS infection. Very few molecular methods for detection of GAS in clinical throat swab specimens have been described. We performed a study of a laboratory-developed internally-controlled rapid Group A streptococcus (GAS) PCR assay using flocked swab throat specimens. We compared the GAS PCR assay to GAS culture results using a collection of archived throat swab samples obtained during a study comparing the performance of conventional and flocked throat swabs. The sensitivity of the GAS PCR assay as compared to the reference standard was 96.0% (95% CI 90.1% to 98.4%), specificity 98.6% (95% CI 95.8% to 99.5%), positive predictive value (PPV) 96.9% (95% CI 91.4% to 99.0%) and negative predictive value (NPV) of 98.1% (95% CI 95.2% to 99.2%). For conventional swab cultures, sensitivity was 96.0% (95% CI 90.1% to 98.4%), specificity 100% (95% CI 98.2% to 100%), PPV 100%, (95% CI 96.1% to 100%) and NPV 98.1% (95% CI 95.2% to 99.3%) In this retrospective study, the GAS PCR assay appeared to perform as well as conventional throat swab culture, the current standard of practice. Since the GAS PCR assay, including DNA extraction, can be performed in approximately 1 hour, prospective studies of this assay are warranted to evaluate the clinical impact of the assay on management of patients with pharyngitis.

To assess the diagnostic usefulness of temporal artery biopsy in temporal arteritis (TA) and establish clinical features capable of predicting its positivity we have retrospectively studied the biopsy specimens and the clinical features of 103 patients who had undergone temporal artery biopsy. Temporal artery biopsy reached a positive predictive value of 90.2% with respect to the final diagnosis based on the criteria proposed by Ellis and Ralston and the clinical course. The simultaneous presence of recent onset headache, jaw claudication, and abnormalities of the temporal arteries on physical examination had a specificity of 94.8% with respect to the histological diagnosis and of 100% with respect to final diagnosis. The presence of any of these clinical features, though of little specificity (34.4%), had a sensitivity of 100% with respect to histological diagnosis, selecting a group of patients in whom temporal artery biopsy has more discriminative value.

Although total hip arthroplasty is one of the most common orthopaedic surgical procedures, it remains unclear whether histopathological examination of the excised femoral head adds to the quality of patient care. We propose that assessment of femoral heads resected during total hip arthroplasty and donated for allograft use may provide a profile of femoral head pathology that benefits total hip arthroplasty patients and bone donors. We retrospectively analyzed the histological findings reported for 6161 femoral heads donated for allograft use between 1993 and 2006. Specimens obtained during total hip arthroplasty and specimens donated at death were reviewed. Follow-up investigations that resulted from abnormal histopathological findings were also reviewed. The Western Australian Cancer Registry was used to determine whether patients with a suspected neoplasm were subsequently diagnosed with such a disease. A retrospective review of the histopathological findings was conducted to evaluate and reclassify all previous observations of abnormalities. One hundred and five femoral heads demonstrated abnormal or reactive histopathological features not reported prior to surgery and were rejected for allograft use. A reactive lymphocytic infiltrate, most likely due to osteoarthritis, was the most commonly identified feature (forty-five cases). Other features observed in twenty-seven cases were also most likely due to the presence of severe osteoarthritis. Ten femoral heads demonstrated plasmacytosis, which may have been related to osteoarthritis. Two patients were diagnosed with Paget's disease, and two, with rheumatoid arthritis. Nineteen patients had a suspected neoplasm. Of these nineteen, eight cases of non-Hodgkin's lymphoma or chronic lymphocytic leukemia and one case of myelodysplastic syndrome were confirmed on further investigation. One subsequently confirmed malignancy was detected per 770 femoral heads examined. Our findings indicate that, even with a detailed

Clinical Pharmacist Practitioners are advanced practicing pharmacists in North Carolina that provide disease-specific management. The purpose of this retrospective cohort study was to compare the efficacy and charges from referrals to a Clinical Pharmacist Practitioner by the primary care provider, to those managed by a primary care provider alone. Patients were separated into cohorts depending if they had at least two appointments with a Clinical Pharmacist Practitioner from November 2008 to November 2011. A primary care provider saw all patients at least twice during the study period. Cohorts were then matched by age, gender, and disease states. Medicare billed data was evaluated from outpatient visits related to hypertension, diabetes mellitus, and peripheral neuropathy, as well as emergency department visits and inpatient admissions. Cost of medications was estimated using 2009 AWP data corresponding to medication histories within the electronic medical record. Efficacy was defined as ability to reach disease state goal determined using national guidelines and reduction in pain score. Efficacy was analyzed by difference-in-differences test and all other numerical data tested by paired t-tests. The Clinical Pharmacist Practitioners cohort experienced more outpatient visits (1338 vs. 858, p < 0.001), fewer emergency department visits (115 vs. 190, p < 0.05), and similar inpatient admissions (88 vs. 117, p > 0.05) than the primary care providers cohort, respectively. The Clinical Pharmacist Practitioners cohort showed changes in charges of +22.6 % for outpatient visits, -45.5 % emergency department visits, and -13.2 % inpatient admissions relative to the primary care provider cohort. There was no difference in average daily medication cost (Clinical Pharmacist Practitioners $38.52 vs. primary care providers $38.23, p = 0.97) or achievement of disease state goals. APPLE-NC demonstrated that through referrals, Clinical Pharmacist Practitioners

The purpose of this study was to collect knee laxity data using a robotic testing device. The data collected were then compared to the results obtained from manual clinical examination. Two human cadavers were studied. A medial collateral ligament (MCL) tear was simulated in the left knee of cadaver 1, and a posterolateral corner (PLC) injury was simulated in the right knee of cadaver 2. Contralateral knees were left intact. Five blinded examiners carried out manual clinical examination on the knees. Laxity grades and a diagnosis were recorded. Using a robotic knee device which can measure knee laxity in three planes of motion: anterior-posterior, internal-external tibia rotation, and varus-valgus, quantitative data were obtained to document tibial motion relative to the femur. One of the five examiners correctly diagnosed the MCL injury. Robotic testing showed a 1.7° larger valgus angle, 3° greater tibial internal rotation, and lower endpoint stiffness (11.1 vs. 24.6 Nm/°) in the MCL-injured knee during varus-valgus testing when compared to the intact knee and 4.9 mm greater medial tibial translation during rotational testing. Two of the five examiners correctly diagnosed the PLC injury, while the other examiners diagnosed an MCL tear. The PLC-injured knee demonstrated 4.1 mm more lateral tibial translation and 2.2 mm more posterior tibial translation during varus-valgus testing when compared to the intact knee. The robotic testing device was able to provide objective numerical data that reflected differences between the injured knees and the uninjured knees in both cadavers. The examiners that performed the manual clinical examination on the cadaver knees proved to be poor at diagnosing the injuries. Robotic testing could act as an adjunct to the manual clinical examination by supplying numbers that could improve diagnosis of knee injury. Level II.

The purpose of this study was to analyze opinions about the action plan for implementation of clinical performance exam as part of the national nursing licensing examination and presents the expected effects of the performance exam and aspects to consider regarding its implementation. This study used a mixed-methods design. Quantitative data were collected by a questionnaire survey, while qualitative data were collected by focus group interviews with experts. The survey targeted 200 nursing professors and clinical nurses with more than 5 years of work experience, and the focus group interviews were conducted with 28 of professors, clinical instructors, and nurses at hospitals. First, nursing professors and clinical specialists agreed that the current written tests have limitations in evaluating examinees' ability, and that the introduction of a clinical performance exam will yield positive results. Clinical performance exam is necessary to evaluate and improve nurses' work ability, which means that the implementation of a performance exam is advisable if its credibility and validity can be verified. Second, most respondents chose direct performance exams using simulators or standardized patients as the most suitable format of the test. In conclusion, the current national nursing licensing exam is somewhat limited in its ability to identify competent nurses. Thus, the time has come for us to seriously consider the introduction of a performance exam. The prerequisites for successfully implementing clinical performance exam as part of the national nursing licensing exam are a professional training process and forming a consortium to standardize practical training.

The aim of this study was to retrospectively evaluate the clinical performance of porcelain laminate veneer restorations delivered by undergraduate students at the Department of Restorative Dentistry, University Dental School and Hospital Cork and to analyze the factors that influence their prognosis and their effect on periodontal health. Patients who had veneers fitted over a period of 5 yrs. were recalled for evaluation. The recall protocol took the form of a questionnaire and a full clinical examination of the teeth involved and contra lateral control teeth. In all, 29 patients with 62 porcelain veneers were examined, only 2 of which were in the mandible. 77% of patients had veneers fitted due to discolouration, 13% in order to alter the shape or size of teeth and 10% due to palatal erosion. On the date of recall 89% of veneers had never debonded or fractured, 6% had to be rebonded since the date of insertion and 5% presented with a fracture. From this study it appears that porcelain laminate veneers are successful in the treatment of discoloured and irregular configured anterior teeth. It shows that undergraduate students can deliver satisfactory veneer restorations.

This study investigated the amounts of problem-solving process information ("action," "why," "how," and "metacognitive") elicited by means of concurrent, retrospective, and cued retrospective reporting. In a within-participants design, 26 participants completed electrical circuit troubleshooting tasks under different reporting conditions. The method of cued retrospective reporting used the original computer-based task and a superimposed record of the participant's eye fixations and mouse-keyboard operations as a cue for retrospection. Cued retrospective reporting (with the exception of why information) and concurrent reporting (with the exception of metacognitive information) resulted in a higher number of codes on the different types of information than did retrospective reporting.

To characterize the clinical presentation and outcome of dogs with acute liver failure (ALF). Retrospective case series from January 1995 to December 2012. University teaching hospital. Forty-nine dogs were diagnosed with ALF defined as the acute onset of clinical signs accompanied by serum hyperbilirubinemia and coagulopathy (prothrombin time >1.5 times the upper limit of the reference interval) with or without signs of hepatic encephalopathy. Medical records were retrospectively analyzed for clinical presentation, history, physical examination findings, clinicopathologic data, diagnostic imaging findings, hepatic histopathology, treatment, and outcome. Presenting signs included anorexia (28/49, 57%), vomiting (25/49, 51%), neurologic abnormalities (17/49, 35%), and polydipsia/polyuria (10/49, 20%). Neurologic impairment compatible with hepatic encephalopathy occurred at some point during hospitalization in 28/49 (57%) of dogs. Common clinicopathologic abnormalities on presentation other than hyperbilirubinemia and increased serum liver enzyme activity included thrombocytopenia (25/49, 51%), hypoalbuminemia (23/49, 46%), leukocytosis (17/49, 34%), anemia (14/49, 29%), hypokalemia (13/49, 27%), and hypoglycemia (10/49, 20%). The causes of ALF included neoplasia (13/49, 27%), presumptive leptosporosis (4/49, 8%), and ischemia (1/49, 2%). The remaining cases were idiopathic although 15 of these dogs had exposure to possible hepatotoxins. Common lesions in the 35/49 (71%) dogs that had hepatic histopathology were necrosis (19/39, 48%), lipidosis (16/39, 41%), vacuolar change (7/49, 14%), and inflammation (4/49, 8%). Complications included ascites (20/49, 41%), bleeding tendencies (14/49, 29%), pancreatitis (12/49, 24%), and acute tubular necrosis (11/49, 22%). Seven (14%) dogs survived to discharge. Survivors had higher alanine aminotransferase activity, and were more likely to maintain normal albumin concentrations and not develop clinical bleeding or ascites during

To assess the effect of baseline variables, including treatment, on clinical cure and survival rates in patients with Gram-positive, ventilator-associated pneumonia (VAP). Retrospective analysis of two randomized, double-blind studies. Multinational study with 134 sites. 544 patients with suspected Gram-positive VAP, including 264 with documented Gram-positive VAP and 91 with methicillin-resistant S. aureus (MRSA) VAP. Linezolid 600 mg or vancomycin 1 g every 12 h for 7-21 days, each with aztreonam. Clinical cure rates assessed 12-28 days after the end of therapy and excluding indeterminate or missing outcomes significantly favored linezolid in the Gram-positive and MRSA subsets. Logistic regression showed that linezolid was an independent predictor of clinical cure with odds ratios of 1.8 for all patients, 2.4 for Gram-positive VAP, and 20.0 for MRSA VAP. Kaplan-Meier survival rates favored linezolid in the MRSA subset. Logistic regression showed that linezolid was an independent predictor of survival with odds ratios of 1.6 for all patients, 2.6 for Gram-positive VAP, and 4.6 for MRSA VAP. Initial linezolid therapy was associated with significantly better clinical cure and survival rates than was initial vancomycin therapy in patients with MRSA VAP.

To characterize the epidemiologic, clinical, laboratory, and radiographic findings from dogs with polyarthritis (PA). Retrospective clinical study. Forty dogs. Medical records of 40 dogs with a diagnosis of PA were reviewed. Retrieved data included breed, age at admission, sex, weight, clinical signs, and the results of synovial fluid analysis, complete blood count, serum chemistry profile, urinalysis, serologic screening tests for infectious diseases, and radiographic examination of affected joints. The incidence of PA was 0.37%. Twenty-nine breeds were represented; 16 dogs were male, and 24 were female. Mean body weight was 20.1 +/- 15 kg. The mean age at admission was 5.6 +/- 4 years. Eighty percent of dogs with PA had difficulty or reluctance walking, 35% were lame, 33% had spontaneous vocalization without any obvious reason, 20% had exercise intolerance, 18% were febrile, and 7.5% had an inability to rise or move. Joint pain was identified in 40% of dogs. Synovial fluid color varied from colorless (36%) to yellow-tinged (36%) or hemorrhagic (28%). Synovial fluid mean cell count varied from 10 cells (400x) to 50 cells (1,000x). Leukocytosis occurred in 59% of the dogs and was more frequently identified in dogs with very severe synovial inflammation. Thirty-one percent of affected dogs were anemic. Serum biochemical profiles were considered abnormal in 13% of the dogs. Joint radiography did not identify erosive arthritis. PA is a common cause of locomotor abnormalities in dogs; however, true lameness and articular pain are not common clinical findings in dogs with PA. PA should be considered in the differential diagnosis for all dogs with difficulty walking. Copyright 2002 by The American College of Veterinary Surgeons

Few studies have reported long-term data on mortality rates for children admitted to hospital with pneumonia in Africa. We examined trends in case fatality rates for all-cause clinical pneumonia and its risk factors in Malawian children between 2001 and 2012. Individual patient data for children (<5 years) with clinical pneumonia who were admitted to hospitals participating in Malawi's Child Lung Health Programme between 2001 and 2012 were recorded prospectively on a standardised medical form. We analysed trends in pneumonia mortality and children's clinical characteristics, and we estimated the association of risk factors with case fatality for children younger than 2 months, 2-11 months of age, and 12-59 months of age using separate multivariable mixed effects logistic regression models. Between November, 2012, and May, 2013, we retrospectively collected all available hard copies of yellow forms from 40 of 41 participating hospitals. We examined 113 154 pneumonia cases, 104 932 (92·7%) of whom had mortality data and 6903 of whom died, and calculated an overall case fatality rate of 6·6% (95% CI 6·4-6·7). The case fatality rate significantly decreased between 2001 (15·2% [13·4-17·1]) and 2012 (4·5% [4·1-4·9]; ptrend<0·0001). Univariable analyses indicated that the decrease in case fatality rate was consistent across most subgroups. In multivariable analyses, the risk factors significantly associated with increased odds of mortality were female sex, young age, very severe pneumonia, clinically suspected Pneumocystis jirovecii infection, moderate or severe underweight, severe acute malnutrition, disease duration of more than 21 days, and referral from a health centre. Increasing year between 2001 and 2012 and increasing age (in months) were associated with reduced odds of mortality. Fast breathing was associated with reduced odds of mortality in children 2-11 months of age. However, case fatality rate in 2012 remained high for children with very

What factors does multivariate logistic regression show to be significantly associated with the likelihood of clinical pregnancy in vitrified-warmed embryo transfer (VET) cycles? Assisted hatching (AH) and if the reason to freeze embryos was to avoid the risk of ovarian hyperstimulation syndrome (OHSS) were significantly positively associated with a greater likelihood of clinical pregnancy. Single factor analysis has shown AH, number of embryos transferred and the reason of freezing for OHSS to be positively and damaged blastomere to be negatively significantly associated with the chance of clinical pregnancy after VET. It remains unclear what factors would be significant after multivariate analysis. The study was a retrospective analysis of 2313 VET cycles from 1481 patients performed between January 2008 and April 2012. A multivariate logistic regression analysis was performed to identify the factors to affect clinical pregnancy outcome of VET. There were 22 candidate variables selected based on clinical experiences and the literature. With the thresholds of α entry = α removal= 0.05 for both variable entry and variable removal, eight variables were chosen to contribute the multivariable model by the bootstrap stepwise variable selection algorithm (n = 1000). Eight variables were age at controlled ovarian hyperstimulation (COH), reason for freezing, AH, endometrial thickness, damaged blastomere, number of embryos transferred, number of good-quality embryos, and blood presence on transfer catheter. A descriptive comparison of the relative importance was accomplished by the proportion of explained variation (PEV). Among the reasons for freezing, the OHSS group showed a higher OR than the surplus embryo group when compared with other reasons for VET groups (OHSS versus Other, OR: 2.145; CI: 1.4-3.286; Surplus embryos versus Other, OR: 1.152; CI: 0.761-1.743) and high PEV (marginal 2.77%, P = 0.2911; partial 1.68%; CI of area under receptor operator characteristic

To evaluate at what age parous and nonparous women were diagnosed with breast cancer. Factors taken into account for parous women were whether they had breastfed their children, and if so, the length of the lactation period. Other factors considered for both groups were obesity, family histories of cancer, smoking habits and alcohol consumption. Breast cancer is the most common form of cancer in younger women in Western countries. Its growing incidence as well as the increasingly early age of diagnosis led us to carefully analyse its possible causes and the preventive measures to be taken. This is a particularly important goal in epidemiological research. A retrospective study of the clinical histories of patients diagnosed with breast cancer at the San Cecilio University Hospital in Granada (Spain). In this study, we analysed 504 medical records of female patients, 19-91 years of age, who had been diagnosed and treated for breast cancer from 2004-2009 at the San Cecilio University Hospital in Granada (Spain). Relevant data (age of diagnosis, period of lactation, family history of cancer, obesity, alcohol consumption and smoking habits) were collected from the clinical histories of each patient and analysed. A conditional inference tree was used to relate the age of diagnosis to smoking habits and the length of the lactation period. The conditional inference tree identified significant differences between the age of the patients at breast cancer diagnosis, smoking habits (p < 0·001) and lactation period if the subjects had breastfed their children for more than six months (p = 0·006), regardless of whether they had a family history of cancer. Our study concluded that breastfeeding for over six months not only provides children with numerous health benefits, but also protects mothers from breast cancer when the mothers are nonsmokers. Nurses play a crucial role in encouraging new mothers to breastfeed their children, and this helps to prevent breast cancer. �

Children are at higher risk of renal injury from blunt trauma than adults due to a variety of anatomic factors such as decreased perirenal fat, weaker abdominal muscles, and a less ossified thoracic cage. Non-operative management is gaining in popularity for even major injuries, although there are no universally accepted guidelines. We present a retrospective review of pediatric major blunt renal injuries (grade 3 or higher) at a children's hospital in Hawai‘i over a 5-year period. Medical records were examined between January 2009 and September 2014 from Kapi‘olani Medical Center for Women and Children in Honolulu, Hawai‘i. Inclusion criteria were a diagnosis of renal trauma, or the diagnosis of blunt abdominal trauma with hematuria. Exclusion criteria were grade I or II renal injury or death due to an additional traumatic injury. Mechanism of injury, clinical characteristics on admission, blood product requirements, surgical interventions performed, and hospital length of stay were retrospectively analyzed. Eleven total patient records were examined, nine of which fit inclusion criteria. Uniquely, 33% of patients sustained their renal injury while surfing. No patients required laparotomy or nephrectomy, though 22% of patients received a blood transfusion and 44% of patients underwent ureteral stent placement. Non-operative management of major renal injuries in children is feasible and allows for preservation of renal tissue. A novel mechanism of surfing as a cause of major renal trauma is seen in the state of Hawai‘i. PMID:28484665

Although giant cell arteritis (GCA) is a well-known cause of transient and permanent vision loss, diplopia as a presenting symptom of this condition is uncommon. We compared symptoms and signs of patients presenting with diplopia from GCA to those from other causes. This was a multicenter, retrospective study comparing the clinical characteristics of patients presenting with diplopia from GCA with age-matched controls. Demographic information, review of symptoms, ophthalmic examination, and laboratory data of biopsy-proven patients with GCA were compared with those of age-matched controls presenting with diplopia. A total of 27 patients presented with diplopia from GCA, 19 with constant diplopia, and 8 with transient diplopia. All patients with constant diplopia from GCA were matched with 67 control subjects who had diplopia from other etiologies. Patients with GCA were more likely to describe other accompanying visual symptoms (58% vs 25%, P = 0.008), a greater number of systemic GCA symptoms (3.5, GCA vs 0.6, controls, P < 0.001) such as headache (94% [17/18] vs 39% [23/67]; P < 0.001), jaw claudication (80% [12/15] vs 0% [0/36]; P < 0.001), and scalp tenderness (44% [7/16] vs 7% [3/43]; P < 0.001). Ocular ischemic lesions (26% vs 1%, P < 0.001) were also common in patients with diplopia from GCA. Inflammatory markers were elevated significantly in patients with GCA vs controls (erythrocyte sedimentation rate: 91% [10/11] vs 12% [3/25], P < 0.001; C-reactive protein: 89% [8/9] vs 11% [2/19], P < 0.001). GCA is a rare but serious cause of diplopia among older adults and must be differentiated from other more common benign etiologies. Our study suggests that most patients with diplopia from GCA have concerning systemic symptoms and/or elevated inflammatory markers that should trigger further work-up. Moreover, careful ophthalmoscopic examination should be performed to look for presence of ocular ischemic lesions in older patients presenting with acute diplopia.

There is great variation in the knowledge base of Emergency Medicine (EM) interns in July. The first objective knowledge assessment during residency does not occur until eight months later, in February, when the American Board of EM (ABEM) administers the in-training examination (ITE). In 2013, the National Board of Medical Examiners (NBME) released the EM Advanced Clinical Examination (EM-ACE), an assessment intended for fourth-year medical students. Administration of the EM-ACE to interns at the start of residency may provide an earlier opportunity to assess the new EM residents' knowledge base. The primary objective of this study was to determine the correlation of the NBME EM-ACE, given early in residency, with the EM ITE. Secondary objectives included determination of the correlation of the United States Medical Licensing Examination (USMLE) Step 1 or 2 scores with early intern EM-ACE and ITE scores and the effect, if any, of clinical EM experience on examination correlation. This was a multi-institutional, observational study. Entering EM interns at six residencies took the EM-ACE in July 2013 and the ABEM ITE in February 2014. We collected scores for the EM-ACE and ITE, age, gender, weeks of clinical EM experience in residency prior to the ITE, and USMLE Step 1 and 2 scores. Pearson's correlation and linear regression were performed. Sixty-two interns took the EM-ACE and the ITE. The Pearson's correlation coefficient between the ITE and the EM-ACE was 0.62. R-squared was 0.5 (adjusted 0.4). The coefficient of determination was 0.41 (95% CI [0.3-0.8]). For every increase of one in the scaled EM-ACE score, we observed a 0.4% increase in the EM in-training score. In a linear regression model using all available variables (EM-ACE, gender, age, clinical exposure to EM, and USMLE Step 1 and Step 2 scores), only the EM-ACE score was significantly associated with the ITE (p<0.05). We observed significant colinearity among the EM-ACE, ITE and USMLE scores. Gender

  The aim was to study the clinical characteristics of Duane's retraction syndrome (DRS) in Nepalese patients.   Medical records from 52 cases of DRS from May 2003 to April 2010 were retrospectively reviewed for age, gender, laterality and clinical characteristics. Forty-one case records (78.8 per cent) that had complete clinical findings were considered for further evaluation. Examination included visual acuity by Snellen chart, refraction, associated horizontal and vertical strabismus in primary gaze, upshoot and downshoot on attempted adduction, binocular vision assessed with the Worth four-dot test on adopted gaze and stereopsis examined with the Titmus stereo test.   DRS type I was the most common type observed in 73.2 per cent of cases, followed by DRS type II (14.6 per cent) and DRS type III (12.2 per cent). It was more common in female patients (58.5 per cent) than male patients (χ(2) = 4.6, df = 1, p = 0.03). DRS was more common in the left eye (68.3 per cent) than the right eye and unilaterally present in 95.1 per cent of subjects. In primary gaze, orthotropia (41.5 per cent) was more common than exotropia (34.1 per cent) and esotropia (24.4 per cent) and vertical strabismus was present in 24.4 per cent of subjects. Upshoot and downshoot on attempted adduction was seen in 14.6 and 9.8 per cent, respectively. Binocular single vision was present in 68.3 per cent of subjects by Worth four-dot test at near. Stereopsis of 3,000 seconds of arc was present in 9.8 per cent, 100 to 200 seconds of arc in 14.6 per cent and 40 to 60 seconds of arc in 43.9 per cent with the Titmus stereo test.   DRS is more common in female patients and the left eye. DRS type I is the most common type. © 2011 The Authors. Clinical and Experimental Optometry © 2011 Optometrists Association Australia.

Clinical inertia in type 2 diabetes: A retrospective analysis of pharmacist-managed diabetes care vs. usual medical care

PubMed Central

Yam, Felix K.; Adams, Aimee G.; Divine, Holly; Steinke, Douglas; Jones, Mikael D.

Background Evidence suggests that patients with type 2 diabetes (T2DM) suffer from a high rate of “clinical inertia” or “recognition of the problem but failure to act.” Objective The aim of this study is to quantify the rate of clinical inertia between two models of care: Pharmacist-Managed Diabetes Clinic (PMDC) vs. Usual Medical Care (UMC). Methods Patients in a university based medical clinic with type 2 diabetes (T2DM) were analyzed in this retrospective cohort study. Patients were exposed to either PMDC or UMC. The difference in days to intervention in response to suboptimal laboratory values and time to achieve goal hemoglobin A1c (A1c), systolic blood pressure (SBP) and low-density lipoprotein (LDL) was compared in the two models of care. Results A total of 113 patients were included in the analysis of this study, 54 patients were in the PMDC and 59 patients were in the UMC group. Median time (days) to intervention for A1c values >7% was 8 days and 9 days in the PMDC and UMC groups, respectively (p>0.05). In patients with baseline A1c values >8%, median time to achieving A1c<7% was 259 days vs. 403 days in the PMDC and UMC groups, respectively (p<0.05). Median time to goal SBP was 124 days in the PMDC group and 532 days in the UMC group (p<0.05). Median time to goal LDL was 412 days in the PMDC group vs. 506 days in the UMC group (p<0.05). Conclusions Rates of clinical inertia, defined as time to intervention of suboptimal clinical values, did not differ significantly between patients enrolled in a PMDC compared to patients with UMC with respect to A1c, SBP and LDL. Participation in PMDC, however, was associated with achieving goal A1c, SBP, and LDL levels sooner compared to UMC. PMID:24367460

Intimate gynaecological examinations are part of the necessary retinue in gynaecological consultation and management. To evaluate women's perception of digital and speculum vaginal examinations in rural Southeast Nigeria. This was a prospective descriptive study. Gynaecologic clinic attendees in a Mission hospital in rural Nigeria were interviewed using a pre-tested questionnaire over a 3-year period. Four hundred and eighty-six women with a mean age of 35.2 ± 8.1 years were interviewed. They presented mainly for infertility (36.8%), menstrual abnormalities (31.1%) and early pregnancy complications (10.7%). Over a quarter of the women felt embarrassed at vaginal examination and 37.2% found it a bit painful or felt discomfort. In spite of the discomfort, 73.7% believed vaginal examination was necessary and over 95% indicated readiness to undergo such examination in future if necessary. Performing intimate gynaecological examination should be a carefully planned procedure with patient's consent, and performed conscientiously taking patient's feelings and emotions into consideration, to engender confidence.

The objective of this study was to examine the clinical findings, magnetic resonance imaging (MRI), pathological features, and treatment experiments of patients with hypertrophic cranial pachymeningitis (HCP). The clinical findings, MRI, and pathological appearances of 9 patients with HCP were analyzed retrospectively. The thickened dura mater was markedly enhanced after contrast media injection. The lesion near the brain hemisphere presented long regions of T1- and T2-weighted abnormal signal intensities. The abnormal signal intensities of the brain tissue were decreased significantly. Pathological examination demonstrated chronic inflammation changes, with cerebral dura mater fibrous tissue showing obvious hyperplasia, and the periphery of the blood vessel showing a great quantity of infiltrating phlegmonosis cells. HCP mainly presents headache and paralysis of multiple cranial nerves. The distinctive signs on brain MRIs involve strengthening the signal in the cerebral dura.

We performed a retrospective analysis to evaluate clinical and economic outcomes in patients receiving remobilization therapy after primary mobilization failure. Our primary endpoint was to compare filgrastim plus plerixafor to other regimens in their ability to collect a target cell dose of at least 2 million CD34+ cells/kg (cumulative). Of 96 consecutive patients who failed their primary mobilization therapy and in whom a second mobilization was attempted, remobilization consisted of filgrastim plus plerixafor (n = 38), filgrastim with or without sargramostim (n = 43), or chemotherapy plus filgrastim (n = 15), 84% of filgrastim/plerixafor patients were able to collect at least 2 million CD34+ cells/kg from both mobilizations, compared to 60% of patients mobilized with chemotherapy/filgrastim and 79% of the filgrastim ± sargramostim patients (P = 0.17). However, when combined with cells collected from the first mobilization, 53% of filgrastim/plerixafor patients reached the target of 2 million CD34+ cells in one apheresis, compared to 20% of those receiving chemotherapy/filgrastim and 28% of those receiving filgrastim ± sargramostim (P = 0.02). Resource utilization, mobilization drug costs, clinical care costs, and total costs were significantly different. We conclude that while filgrastim/plerixafor is the most efficient remobilization strategy, those clinical benefits may not translate into lower cost, especially when multiple days of plerixafor administration are required.

The clinical examination alone is widely considered unreliable when assessing fluid responsiveness in critically ill patients. Little evidence exists on the performance of the clinical examination to predict other hemodynamic derangements or more complex hemodynamic states. Patients with acute febrile illness were assessed on admission, both clinically and per non-invasive hemodynamic measurement. Correlations between clinical signs and hemodynamics patterns were analyzed, and the predictive capacity of the clinical signs was examined. Seventy-one patients were included; the most common diagnoses were bacterial sepsis, scrub typhus and dengue infection. Correlations between clinical signs and hemodynamic parameters were only statistically significant for Cardiac Index (r=0.75, p-value <0.01), Systemic Vascular Resistance Index (r=0.79, p-value <0.01) and flow time corrected (r=0.44, p-value 0.03). When assessing the predictive accuracy of clinical signs, the model identified only 62% of hemodynamic states correctly, even less if there was more than one hemodynamic abnormality. The clinical examination is not reliable to assess a patient's hemodynamic status in acute febrile illness. Fluid responsiveness, cardiodepression and more complex hemodynamic states are particularly easily missed.

Medical students may not be able to identify the essential elements of situational awareness (SA) necessary for clinical reasoning. Recent studies suggest that students have little insight into cognitive processing and SA in clinical scenarios. Objective Structured Clinical Examinations (OSCEs) could be used to assess certain elements of situational awareness. The purpose of this paper is to review the literature with a view to identifying whether levels of SA based on Endsley's model can be assessed utilising OSCEs during undergraduate medical training. A systematic search was performed pertaining to SA and OSCEs, to identify studies published between January 1975 (first paper describing an OSCE) and February 2017, in peer reviewed international journals published in English. PUBMED, EMBASE, PsycINFO Ovid and SCOPUS were searched for papers that described the assessment of SA using OSCEs among undergraduate medical students. Key search terms included "objective structured clinical examination", "objective structured clinical assessment" or "OSCE" and "non-technical skills", "sense-making", "clinical reasoning", "perception", "comprehension", "projection", "situation awareness", "situational awareness" and "situation assessment". Boolean operators (AND, OR) were used as conjunctions to narrow the search strategy, resulting in the limitation of papers relevant to the research interest. Areas of interest were elements of SA that can be assessed by these examinations. The initial search of the literature retrieved 1127 publications. Upon removal of duplicates and papers relating to nursing, paramedical disciplines, pharmacy and veterinary education by title, abstract or full text, 11 articles were eligible for inclusion as related to the assessment of elements of SA in undergraduate medical students. Review of the literature suggests that whole-task OSCEs enable the evaluation of SA associated with clinical reasoning skills. If they address the levels of SA, these

Introduction This retrospective cohort study compared clinical and radiographic outcomes of endodontic treatment performed in immature non-vital permanent teeth, by apexification (calcium hydroxide or apical barrier with Mineral Trioxide Aggregate (MTA)), versus revascularization. Methods A comprehensive chart review was performed to obtain a cohort of sequential previously completed cases with recalls. Clinical and radiographic data were collected for 31 treated teeth (19 revascularization and 12 apexification) with an average follow up time of 17 months and a recall rate of 63%. Tooth survival, success rate, and adverse events were analyzed. Changes in radiographic root length, width and area were quantified. Results The majority of treated teeth survived throughout the study period with 30/31 (97%) teeth surviving (18/19 (95%) revascularization, 12/12 apexification). Most cases were also clinically successful with 27/31 (87%) meeting criteria for success, (15/19 (78%) revascularization and 12/12 apexification; non-significant difference). A greater incidence of adverse events was observed in the revascularization group (8/19 (42%) versus 1/12 (11%) in apexification (Risk Ratio= 5.1, p=0.04, 95%CI (0.719, 35.48)). Although more revascularization cases than apexification cases demonstrated an increase in radiographic root area and width, the effect was not statistically significant. Conclusion In this study, revascularization was not superior to other apexification techniques in either clinical or radiographic outcomes. Studies with large subject cohorts, and long follow up periods are needed to evaluate outcomes of revascularization and apexification, while accounting for important co-variants relevant to clinical success.

The proliferation of nurse-led initiatives arising from nurse specialist/practitioner posts in urology is reflected in areas such as the management of bladder cancer, erectile dysfunction, stoma care, and prostate disease. The establishment of the role of urology specialist nurse in one North Oxfordshire hospital led to the development of a nurse-led prostate assessment clinic for male patients with lower urinary tract symptoms arising from benign prostatic hyperplasia. A description of how training was conducted, and the subsequent reappraisal of competency, is given in relation to physical examination and history-taking skills necessary for the development of this initiative.

OBJECTIVES. Cough mixture is the third most commonly abused substance in patients attending the Prince of Wales Hospital Substance Abuse Clinic. The content of the local cough mixture is not well researched. Paranoid psychosis manifesting as persecutory delusions and derogatory hallucination, as well as mood symptoms, is common in these patients. The natural history and outcome of such psychoses associated with cough mixture abuse are not well known. This study aimed to address these questions. METHODS. This was a retrospective study of cough mixture abuse in Hong Kong. Case records of cough mixture abusers currently receiving treatment at the 3 substance abuse clinics at the Prince of Wales Hospital, Alice Ho Miu Ling Nethersole Hospital, and the North District Hospital were retrieved for data collection. The patients' demographic data, duration and intake pattern of cough mixture, and use of any other drugs were documented. The presenting psychopathology, first urine toxicology results, diagnosis, treatment, number of hospitalizations, and course of the illness were also recorded. RESULTS. A total of 63 patients with the diagnosis of cough mixture abuse were identified in the database; 89% were male. The mean +/- SD age of the patients was 34.4 +/- 6.2 years; 67% were single and 83% were unemployed. The mean +/- SD age of onset of cough mixture abuse was 20 +/- 5 years. Psychiatric symptoms developed a mean +/- SD of 7.6 +/- 6.0 years after onset of abuse. According to the ICD-10 Mental and Behavioural Disorders criteria, the top psychiatric diagnoses were substance-induced psychotic disorder (67%), schizophrenia (19%), depressive disorder (11%), and dysthymia (10%). The most common ingredients in the urine sample at first presentation were promethazine (75%), pseudoephedrine (67%), codeine (60%), ephedrine (57%), zopiclone (17%), and hydrocodone (16%). Additionally, 16% of patients were in the priority follow-up group. The mean +/- SD follow-up period was 6

The aim of the present review was to evaluate the contribution of clinical examination and imaging techniques, mainly transvaginal sonography and magnetic resonance imaging (MRI) to diagnose deep infiltrating (DE) locations using prisma statement recommendations. Clinical examination has a relative low sensitivity and specificity to diagnose DE. Independently of DE locations, for all transvaginal sonography techniques a pooled sensitivity and specificity of 79% and 94% are observed approaching criteria for a triage test. Whatever the protocol and MRI devices, the pooled sensitivity and specificity for pelvic endometriosis diagnosis were 94% and 77%, respectively. For rectosigmoid endometriosis, pooled sensitivity and specificity of MRI were 92% and 96%, respectively fulfilling criteria of replacement test. In conclusion, advances in imaging techniques offer high sensitivity and specificity to diagnose DE with at least triage value and for rectosigmoid endometriosis replacement value imposing a revision of the concept of laparoscopy as the gold standard.

This retrospective study evaluated treatment outcome of cast post and core and Composipost systems after 4 yrs of clinical service. 200 patients were included in the study. They were divided in two groups of 100 endodontically treated teeth restored with a post. Group 1: Composipost systems were luted into root canal following the manufacturer's instructions. Group 2: Cast post and cores were cemented into root canal preparations with a traditional technique. The patients were recalled after 6 months, 1, 2 and 4 yrs and clinical and radiographic examinations were completed. Endodontic and prosthodontic results were recorded. Group 1: 95% of the teeth restored with Composiposts showed clinical success; 3% of these samples were excluded for noncompliance and 2% showed endodontic failure. Group 2: Clinical success was found with 84% of teeth restored with cast post and core. 2% of these samples were excluded for noncompliance, 9% showed root fracture, 2% dislodgment of crown and 3% endodontic failure. Statistical evaluation showed significant differences between Groups 1 and 2 (P < 0.001). The results of this retrospective study indicated that the Composipost system was superior to the conventional cast post and core system after 4 yrs of clinical service.

Intracorneal ring segment implantation is an effective and safe method of visual improvement in patients with keratoconus. The aim of our study was to evaluate the long-term clinical outcomes after Keraring implantation for keratoconus in patients older than 40 years. Eleven eyes from 11 patients with keratoconus who underwent femtosecond laser-assisted Keraring implantation for keratoconus were included in this retrospective study. The uncorrected visual acuity (UCVA), corrected visual acuity, keratometric readings, central corneal thickness and thinnest corneal pachymetry were evaluated preoperatively and 6 months after the Keraring implantation. UCVA, BCVA and keratometric readings improved at 6 months postoperatively. Our data showed significant keratometric amelioration and visual improvement after Keraring implantation for keratoconus in patients older than 40 years at 6 months postoperatively.

Shingles is the cutaneous expression of the reactivation of latent varicella zoster virus infection in sensory ganglia. It presents as vesicles in the corresponding dermatome. The condition is called disseminated herpes zoster (DHZ) when more than 2 contiguous dermatomes are affected, more than 20 vesicles are observed outside the initial dermatome, or involvement is systemic. DHZ is rare and most frequently occurs in immunocompromised patients. To describe the epidemiology, predisposing factors, clinical presentation, laboratory findings, and clinical course of patients with DHZ, and to compare the findings in immunocompromised and immunocompetent patients. We analyzed a retrospective case series of adults hospitalized between February 2010 and October 2015. Forty-one patients with virologically confirmed manifestations of DHZ were included. Stress as a trigger factor was detected in 39% and immunodepression in 58.5%. Immunocompromised patients were younger than the immunocompetent patients (mean ages, 60.5 vs 82 years, P<.01). The 8 immunocompetent patients with no detectable trigger factors were older (mean age, 85 years). In 95% of cases, DHZ was initially limited to a single dermatome and then spread to other dermatomes or became disseminated. Thrombocytopenia was detected in 56% of cases. Complication rates were similar in immunocompromised and immunocompetent patients (54% vs 59%, P>.01). Six patients died; there was no difference in mortality between the 2 groups. This study provides evidence on the relationship between DHZ, the presence of underlying immunodepression, and complications. Immunosenescence may play an important role in the onset of this disease in older immunocompetent patients. Copyright © 2016 AEDV. Publicado por Elsevier España, S.L.U. All rights reserved.

Our institute has constructed a new treatment facility for carbon ion scanning beam therapy. The first clinical trials were successfully completed at the end of November 2011. To evaluate patient setup accuracy, positional errors between the reference Computed Tomography (CT) scan and final patient setup images were calculated using 2D-3D registration software. Eleven patients with tumors of the head and neck, prostate and pelvis receiving carbon ion scanning beam treatment participated. The patient setup process takes orthogonal X-ray flat panel detector (FPD) images and the therapists adjust the patient table position in six degrees of freedom to register the reference position by manual or auto- (or both) registration functions. We calculated residual positional errors with the 2D-3D auto-registration function using the final patient setup orthogonal FPD images and treatment planning CT data. Residual error averaged over all patients in each fraction decreased from the initial to the last treatment fraction [1.09 mm/0.76° (averaged in the 1st and 2nd fractions) to 0.77 mm/0.61° (averaged in the 15th and 16th fractions)]. 2D-3D registration calculation time was 8.0 s on average throughout the treatment course. Residual errors in translation and rotation averaged over all patients as a function of date decreased with the passage of time (1.6 mm/1.2° in May 2011 to 0.4 mm/0.2° in December 2011). This retrospective residual positional error analysis shows that the accuracy of patient setup during the first clinical trials of carbon ion beam scanning therapy was good and improved with increasing therapist experience.

Purpose  Shoulder pain and disability pose a diagnostic challenge owing to the numerous etiologies and the potential for multiple disorders to exist simultaneously. The evidence to support the use of clinical tests for superior labral anterior to posterior complex (SLAP) is weak or absent. The purpose of this study is to determine the diagnostic validity of physical examination maneuvers for SLAP lesions by performing a methodologically rigorous, clinically applicable study. Methods  We recruited consecutive new shoulder patients reporting pain and/or disability. The physician took a history and indicated their certainty about each possible diagnosis ("certain the diagnosis is absent/present," or "uncertain requires further testing"). The clinician performed the physical tests for diagnoses where uncertainty remained. Magnetic resonance imaging arthrogram and arthroscopic examination were the gold standards. We calculated sensitivity, specificity, and likelihood ratios (LRs) and investigated whether combinations of the top tests provided stronger predictions. Results  Ninety-three patients underwent physical examination for SLAP lesions. When using the presence of a SLAP lesion (Types I-V) as disease positive, none of the tests was sensitive (10.3-33.3) although they were moderately specific (61.3-92.6). When disease positive was defined as repaired SLAP lesion (including biceps tenodesis or tenotomy), the sensitivity (10.5-38.7) and specificity (70.6-93.8) of tests improved although not by a substantial amount. None of the tests was found to be clinically useful for predicting repairable SLAP lesions with all LRs close to one. The compression rotation test had the best LR for both definitions of disease (SLAP tear present = 1.8 and SLAP repaired = 1.67). There was no optimal combination of tests for diagnosing repairable SLAP lesions, with at least two tests positive providing the best combination of measurement properties (sensitivity 46.1% and

Patients with a fracture in the anterior pelvic ring often simultaneously demonstrate pain in the posterior pelvic ring. The aim of the present prospective study was to assess the sensitivity of CT, MRI and clinical examination in the detection of fractures in the posterior pelvic ring in patients with fractures of the anterior pelvic ring diagnosed in conventional radiographs. Sixty patients with radiographic signs of an anterior pelvic ring injury were included in this prospective analysis. Following a focused clinical examination of the posterior pelvis, all patients underwent both a CT and then a MRI scan of their pelvis. Two board certified radiologists evaluated the CT and MRI scans independently. To estimate the presence of osteoporosis the Hounsfield units of the vertebral body of L5 were measured in each case. Fifty-three women and seven men, with a mean age of 74.7+/-15.6 years were included into the study. A fracture of the posterior pelvic ring was found in fourty-eight patients (80%) patients using MRI. Fractures of the posterior pelvic ring would have been missed in eight cases (17%), if only CT had been used. Eighty-five percent of the patients with a posterior fracture had an osteoporosis. The majority of the cases suffered from a low energy trauma. Thirty-eight patients (83%) with positive clinical signs at the posterior pelvic ring actually had a fracture of the posterior pelvic ring in the MRI. The clinical examination proved to be equally effective to CT in detecting posterior pelvic ring fractures. The significance of both, clinical examination and CT was confirmed in the detection of fractures in the posterior pelvic ring. MRI examination of the pelvis however, was found to be superior in detecting undislocated fractures in a cohort of patients with a high incidence of osteoporosis. Using MRI may be beneficial in select cases, especially when reduced bone density is suspected. Copyright © 2014 Elsevier Ltd. All rights reserved.

Increasing attention has been given to the possible association of cervical spine (c-spine) injuries with abusive head trauma (AHT). The aims of this study were to describe c-spine MRI findings in hospitalized AHT patients. This is a retrospective study of children under the age of 5 years with AHT admitted to hospital in 2004-2013. Those with c-spine MRI were identified, and the images were reviewed. 250 AHT cases were identified, with 34 (14%) undergoing c-spine MRI. Eleven patients (32%) had 25 findings, including hematoma in 2, occiput-C1-C2 edema in 3, prevertebral edema in 6, facet edema in 2, and interspinous and/or muscular edema in 10. No patients had a clinically evident c-spine injury, a clinically unstable c-spine, or required c-spine surgery. C-spine MRI may identify abnormalities not apparent upon physical examination and the procedure should therefore be considered in cases of suspected AHT. © 2017 S. Karger AG, Basel.

To describe the demographic characteristics, ocular comorbidities, and clinical outcomes of patients with neovascular glaucoma (NVG) and to determine the number of patients who returned for a follow-up eye examination. We examined the clinical data of patients with NVG, who attended a glaucoma clinic between July 2010 and November 2014. We collected information on the demographic characteristics of the patients to include the level of education, ocular comorbidities, NVG stage, visual acuity, glaucoma medications, intraocular pressure (IOP), and the number of patients who had a follow-up ocular examination at month 1, 3, 6, and 12. Data from 350 patients (473 eyes) with NVG were collected. We found 91% of the cohort had proliferative diabetic retinopathy (PDR). We found blindness in both or one eye in 14% and 31% of the cohort respectively. Low vision was found in both or one eye in 14% and 32% of the eyes respectively. By 6 months follow-up, only 32% of the patients were seen at our clinic and by 12 months follow-up, this number decreased to 15%. Around 60% of the patients were on no IOP lowering drugs at the first visit. We found 53% of the cohort had an incomplete elementary school education. The results suggest that advanced NVG is a significant ocular problem for patients referred to our clinic with just over half of the patients presenting as blind. We also found that several socioeconomic factors that had an important role in the development of PDR and NVG, specifically, educational status. We described the characteristics of a large cohort of patients with very advanced NVG, reflecting the fact that the strict control of the underlying disease must be the main goal of the Mexican national health system.

Scientific communication in clinical psychology: examining patterns of citations and references.

PubMed

Kiselica, Andrew M; Ruscio, John

2014-01-01

Previous studies of scientific communication used citation mapping, establishing psychology as a 'hub science' from which many other fields draw information. Within psychology, the clinical and counselling discipline is a major 'knowledge broker'. This study analyzed scientific communication among three major subdisciplines of clinical psychology-the cognitive-behavioural, psychodynamic and humanistic schools of thought-by examining patterns of references within and citations to 305 target articles published in leading journals of these subdisciplines. The results suggest that clinical researchers of each theoretical orientation engage in more insular scientific communication than an integrationist would find desirable and that cognitive-behavioural articles are more closely connected to mainstream psychology and related fields. Eclectic practitioners draw on several different theoretical orientations to inform their practice; as such, they should be interested in understanding the patterns of scientific communication within and across theoretical orientations. Practitioners work in a variety of different mental health settings, with a variety of other professionals in psychology-related fields, and should be interested in how much influence their particular theoretical orientation has on the work of colleagues. Many practitioners rely on new, evidence-based research to inform their work. The results of this study provide these individuals with an objective measure of the influence of empirical work in different areas of clinical psychology. Copyright © 2012 John Wiley & Sons, Ltd.

Evidence suggests that poor performance on standardized tests before and early in medical school is associated with poor performance on standardized tests later in medical school and beyond. This study aimed to explore relationships between standardized examination scores (before and during medical school) with test and clinical performance across all core clinical clerkships. We evaluated characteristics of 435 students at Mayo Medical School (MMS) who matriculated 2000-2009 and for whom undergraduate grade point average, medical college aptitude test (MCAT), medical school standardized tests (United States Medical Licensing Examination [USMLE] 1 and 2; National Board of Medical Examiners [NBME] subject examination), and faculty assessments were available. We assessed the correlation between scores and assessments and determined USMLE 1 cutoffs predictive of poor performance (≤10th percentile) on the NBME examinations. We also compared the mean faculty assessment scores of MMS students vs visiting students, and for the NBME, we determined the percentage of MMS students who scored at or below the tenth percentile of first-time national examinees. MCAT scores correlated robustly with USMLE 1 and 2, and USMLE 1 and 2 independently predicted NBME scores in all clerkships. USMLE 1 cutoffs corresponding to poor NBME performance ranged from 220 to 223. USMLE 1 scores were similar among MMS and visiting students. For most academic years and clerkships, NBME scores were similar for MMS students vs all first-time examinees. MCAT, USMLE 1 and 2, and subsequent clinical performance parameters were correlated with NBME scores across all core clerkships. Even more interestingly, faculty assessments correlated with NBME scores, affirming patient care as examination preparation. USMLE 1 scores identified students at risk of poor performance on NBME subject examinations, facilitating and supporting implementation of remediation before the clinical years. MMS students were

Explore the relationships between preoperative findings and clinical outcome following lumbar disc surgery, and investigate the prognostic value of physical examination findings after accounting for information acquired from the clinical history. We recruited 55 adult patients scheduled for first time, single-level lumbar discectomy. Participants underwent a standardized preoperative evaluation including real-time ultrasound imaging assessment of lumbar multifidus function, and an 8-week postoperative rehabilitation programme. Clinical outcome was defined by change in disability, and leg and low back pain (LBP) intensity at 10 weeks. Linear regression models were used to identify univariate and multivariate predictors of outcome. Univariate predictors of better outcome varied depending on the outcome measure. Clinical history predictors included a greater proportion of leg pain to LBP, pain medication use, greater time to surgery, and no history of previous physical or injection therapy. Physical examination predictors were a positive straight or cross straight leg raise test, diminished lower extremity strength, sensation or reflexes, and the presence of postural abnormality or pain peripheralization. Preoperative pain peripheralization remained a significant predictor of improved disability (p = 0.04) and LBP (p = 0.02) after accounting for information from the clinical history. Preoperative lumbar multifidus function was not associated with clinical outcome. Information gleaned from the clinical history and physical examination helps to identify patients more likely to succeed with lumbar disc surgery. While this study helps to inform clinical practice, additional research confirming these results is required prior to confident clinical implementation.

Self-neglect: adaptation of a clinical tool to the practice of the medical examiner.

Self-neglect is the inability or unwillingness to provide for oneself the goods and services needed to live safely and independently. It is the most common allegation reported to Adult Protective Services agencies throughout the United States. Unfortunately, it seems that most medical examiners and their teams are not trained appropriately on self-neglect and forget to ask pertinent questions and document relevant observations. The most important aspect of self-neglect for the medical examiner is to recognize the diagnosis to avoid confusion with other forms of elder abuse, particularly neglect from a third party. In this context, a self-neglect scale could be a useful tool to assist the death investigation team. In the clinical field, a self-neglect severity scale was developed by the Consortium for Research in Elder Self-Neglect of Texas. It is here proposed that a self-neglect severity scale for medical examiners should be developed, to assist the investigative team in assessing these common cases. This scale is developed by modifying the clinical scale to adapt it to the particular needs of death investigation. This scale can help the medical examiner and his team in approaching these deaths in a systematic and comprehensive way.

To investigate the level of agreement between orthoptists and medical practitioners in the comprehensive eye examination of children seen in an orthoptist-led triage clinic. Patient records over a 6-month period were retrospectively reviewed. Those with a presenting complaint related to vision or ocular motility were triaged into the orthoptist-led clinic and included in the study. Patients who did not meet the triage protocol and those who were not assessed by a medical practitioner at a subsequent appointment were excluded from analysis. The clinical findings from the orthoptist and medical practitioner were collected and compared. In total, sixty-three patients were reviewed during the 6-month period and met the inclusion criteria. After the initial comprehensive eye examination with an orthoptist, thirty-two were discharged from hospital and thirty-one were asked to return for a review appointment with a medical practitioner. Agreement between the orthoptists and medical practitioners for the diagnosis of strabismus and/or amblyopia was 84.6% (κ = 0.649, P < 0.001). There was strong agreement between orthoptists and medical practitioners for refractive error of the right eye [τ (19) = 0.352, P = 0.729] and left eye [τ (19) = 1.785, P = 0.090]. Fundus examination comparisons between the orthoptists and medical practitioners showed very high agreement (95.7%). Orthoptists have the skills necessary to provide comprehensive care of children referred for ocular motility and/or vision related disorders. There was close agreement between orthoptists and medical practitioners when performing comprehensive eye examinations. © 2016 Board of regents of the University of Wisconsin System, American Orthoptic Journal, Volume 66, 2016, ISSN 0065-955X, E-ISSN 1553-4448.

To determine clinical signs and clinicopathologic abnormalities in dogs with naturally occurring clinical spirocercosis. Retrospective case series. 39 dogs with spirocercosis. Medical records were reviewed, and information on signalment, residence (rural vs urban), owner complaints, physical examination findings, clinicopathologic abnormalities, radiographic and endoscopic findings, and concurrent systemic diseases was recorded. Hellenic hounds and mixed-breed dogs were overrepresented, compared with a group of 117 control dogs without spirocercosis that were examined because of gastrointestinal tract disease, and mean body weight of dogs with spirocercosis was significantly higher than mean body weight of control dogs. Odynophagia (34 [87%]), regurgitation (24 [62%]), and excessive salivation (14 [36%]) were the most common clinical findings. The most common radiographic abnormalities were a mass in the caudodorsal aspect of the mediastinum (15/35 [43%]) and spondylitis of the caudal thoracic vertebrae (10 [29%]). Parasitic nodules were seen during esophagoscopy in all 39 dogs. Normocytic, normochromic, nonregenerative anemia; neutrophilic leukocytosis; hyperproteinemia; and high alkaline phosphatase activity were significantly more common in dogs with spirocercosis than in a control group of 56 healthy dogs. Concurrent systemic diseases, mainly leishmaniosis, dirofilariosis, and monocytic ehrlichiosis, were documented in 14 (36%) dogs. Results suggest that clinical spirocercosis occurs more often in young-adult, large-breed dogs. Nonregenerative anemia, neutrophilic leukocytosis, hyperproteinemia, and high alkaline phosphatase activity may be useful clinicopathologic indicators of this disease.

Guidelines from the NCCN ® (National Comprehensive Cancer Network®) advocate digital rectal examination screening only in men with elevated prostate specific antigen. We investigated the effect of prostate specific antigen on the association of digital rectal examination and clinically significant prostate cancer in a large American cohort. We evaluated the records of the 35,350 men who underwent digital rectal examination in the screening arm of the Prostate, Lung, Colorectal and Ovarian Cancer Screening trial for the development of clinically significant prostate cancer (Gleason 7 or greater). Followup was 343,273 person-years. The primary outcome was the rate of clinically significant prostate cancer among men with vs without suspicious digital rectal examination. We performed competing risks regression to evaluate the interaction between time varying suspicious digital rectal examination and prostate specific antigen. A total of 1,713 clinically significant prostate cancers were detected with a 10-year cumulative incidence of 5.9% (95% CI 5.6-6.2). Higher risk was seen for suspicious vs nonsuspicious digital rectal examination. Increases in absolute risk were small and clinically irrelevant for normal (less than 2 ng/ml) prostate specific antigen (1.5% vs 0.7% risk of clinically significant prostate cancer at 10 years), clinically relevant for elevated (3 ng/ml or greater) prostate specific antigen (23.0% vs 13.7%) and modestly clinically relevant for equivocal (2 to 3 ng/ml) prostate specific antigen (6.5% vs 3.5%). Digital rectal examination demonstrated prognostic usefulness when prostate specific antigen was greater than 3 ng/ml, limited usefulness for less than 2 ng/ml and marginal usefulness for 2 to 3 ng/ml. These findings support the restriction of digital rectal examination to men with higher prostate specific antigen as a reflex test to improve specificity. It should not be used as a primary screening modality to improve sensitivity. Copyright �

INTRODUCTION This study examines the relationship between the clinical performance of medical students and their performance as doctors during their internships. METHODS This retrospective study involved 63 applicants of a residency programme conducted at Chonnam National University Hospital, South Korea, in November 2012. We compared the performance of the applicants during their internship with their clinical performance during their fourth year of medical school. The performance of the applicants as interns was periodically evaluated by the faculty of each department, while their clinical performance as fourth-year medical students was assessed using the Clinical Performance Examination (CPX) and the Objective Structured Clinical Examination (OSCE). RESULTS The performance of the applicants as interns was positively correlated with their clinical performance as fourth-year medical students, as measured by the CPX and OSCE. The performance of the applicants as interns was moderately correlated with the patient-physician interaction items addressing communication and interpersonal skills in the CPX. CONCLUSION The clinical performance of medical students during their fourth year in medical school was related to their performance as medical interns. Medical students should be trained to develop good clinical skills through actual encounters with patients or simulated encounters using manikins, to enable them to become more competent doctors.

In the pre-clinical phase of the study of dentistry at the University of Greifswald, the course "Early Patient Contact (EPC)" is conducted within the framework of Community Medicine/Dentistry. The course is based on three pillars: the patient visiting program, special problem-oriented seminars, and communication training for doctors. The essential goal consists of providing students with real patient contact right at the beginning of their study of dentistry, thus making the study of dentistry patient-based very early on. Students are trained in taking comprehensive anamneses and recording clinical findings. Within the framework of the dental preliminary exams, the course is evaluated using an OSCE on a standardized patient. Furthermore, the added value of an additional training unit (conducting anamnesis and clinical examination) in preparation for the OSCE was evaluated. The exam results of a group without training (control group) were compared with those of a group with training (intervention group). The intervention group performed significantly better than the control on the following items: the total number of points achieved on the OSCE early patient contact, and in the most important points of the anamnesis and clinical examination. In addition, the intervention group tended to score higher in terms of the item "oral health status". The present study showed a positive effect of an additional training unit on students' performance in the OSCE. Taking the limitations of the study and the results of a literature review into account, we recommend conducting such training as preparation for the OSCE.

Immediate loading of tapered implants placed in postextraction sockets: retrospective analysis of the 5-year clinical outcome.

The use of immediate implant loading protocols delivers obvious benefits to the patient. When applied in healed sites, this has not only been well documented in the totally edentolous mandible but has also been documented and reported to be predictable in the upper jaw, and in cases of partial edentoulism, as well. A further application of immediate loading protocol, although still controversial, especially when replacing single maxillary teeth in the anterior zone, is the immediate implant placement and provisionalization in postextractive sockets. In consideration of the oxidized surface promoting bone healing and the tapered shape of the implant body, the Replace Select Tapered TiUnite implants have been used for many years in our clinic when facing these clinical situations. This article will report about our long-term clinical experience with such implants and the relevant role of a correct surgical and prosthetic treatment planning. The aim of this retrospective study was to report on the 5-year clinical and radiologic outcome of patients treated with Replace Select Tapered TiUnite implants when used according to an immediate loading protocol in postextraction sites. In routine practice, 56 consecutive patients were treated with 79 implants. The patients, 23 males and 33 females, had a mean age of 50.9 years, range 21-76 years, at implant placement. Forty-seven implants were placed in the maxilla and 32 implants were placed in the mandible. All implants were placed in postextraction sites and were immediately loaded. Provisional restorations were delivered within 2 hours from surgery and all were in occlusion. Forty-three patients received a single implant while in the remaining 13 patients the implants were splinted. Definitive prosthetic restoration was delivered within 1 to 4 months following implant placement. Evaluations of soft tissue health and marginal bone remodeling were conducted. An independent radiologist performed the radiographic evaluation

Knowledge of epidemiology is important for recognition of cardiovascular malformations. Review the incidence of congenital heart defects in dogs in Italy and assess breed and sex predispositions. Nine hundred and seventy-six dogs diagnosed with congenital heart disease (CHD) of 4,480 dogs presented to Clinica Veterinaria Gran Sasso for cardiovascular examination from 1997 to 2010. A retrospective analysis of medical records regarding signalment, history, clinical examination, radiography, electrocardiography, echocardiography, angiography, and postmortem examination was performed. Breed and sex predisposition were assessed with the odds ratio test. CHD was observed in 21.7% of cases. A total of 1,132 defects were observed with single defects in 832 cases (85%), 2 concurrent defects in 132 cases (14%), and 3 concurrent defects in 12 cases (1%). The most common defects were pulmonic stenosis (PS; 32.1%), subaortic stenosis (SAS; 21.3%), and patent ductus arteriosus (20.9%), followed by ventricular septal defect (VSD; 7.5%), valvular aortic stenosis (AS; 5.7%), and tricuspid dysplasia (3.1%). SAS, PS, and VSD frequently were associated with other defects. Several breed and sex predispositions were identified. The results of this study are in accordance with previous studies, with slight differences. The breed and sex predilections identified may be of value for the diagnosis and screening of CHD in dogs. Additionally, the relatively high percentage of concurrent heart defects emphasizes the importance of accurate and complete examinations for identification. Because these data are from a cardiology referral center, a bias may exist. Copyright © 2011 by the American College of Veterinary Internal Medicine.

We performed a retrospective analysis of patients with adult-onset chronic active Epstein-Barr virus infection (CAEBV). First, we analyzed five patients (aged 28-72) diagnosed at our hospitals with EBV-infected clonally proliferating T cells. Four patients were administered cyclophosphamide/doxorubicin/vincristine/prednisone (CHOP) chemotherapy, but no remarkable decrease of viral load was observed in three of the patients. The other patient died 19 days after initiation of CHOP treatment due to disease progression. Addition of high-dose cytarabine to the regimens of two of the patients was discontinued shortly after administration, due to the development of grade 4 pericardial effusion. Together, these regimens may be insufficient for treating adult-onset CAEBV. We next reviewed 23 adult-onset CAEBV patients, adding 18 previously reported patients to the five patients described in the present study. T cells were frequently infected (87%), whereas NK- and T-cell types are known to be almost equally prevalent in childhood-onset cases. The time duration from the onset of disease to initiation of treatment averaged 20 months. Reports showed that 12 patients died; seven patients died at an average of 8 months after initiation of treatment. Patients' disease courses seemed to be rapidly progressive and more aggressive than those of childhood-onset cases. More cases must be studied to clarify clinical features and establish an optimal treatment strategy.

The benefits of retrospective continuous glucose monitoring (retroCGM) recording have been widely explored in clinical studies, and many diabetes physicians routinely use this examination. However, the method of interpretation of CGM recordings has never been precisely described. An expert French panel of physicians met for two days to discuss several aspects of retroCGM use and to produce a position statement. The guidelines cover the indications for retroCGM, the general organization and practical implementation of CGM recordings, a description of the different devices available and guidelines for the interpretation of retroCGM recordings. This consensus document should help clinicians in the proper use of retroCGM. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

Neurology objective structured clinical examination reliability using generalizability theory

2015-01-01

Objectives: This study examines factors affecting reliability, or consistency of assessment scores, from an objective structured clinical examination (OSCE) in neurology through generalizability theory (G theory). Methods: Data include assessments from a multistation OSCE taken by 194 medical students at the completion of a neurology clerkship. Facets evaluated in this study include cases, domains, and items. Domains refer to areas of skill (or constructs) that the OSCE measures. G theory is used to estimate variance components associated with each facet, derive reliability, and project the number of cases required to obtain a reliable (consistent, precise) score. Results: Reliability using G theory is moderate (Φ coefficient = 0.61, G coefficient = 0.64). Performance is similar across cases but differs by the particular domain, such that the majority of variance is attributed to the domain. Projections in reliability estimates reveal that students need to participate in 3 OSCE cases in order to increase reliability beyond the 0.70 threshold. Conclusions: This novel use of G theory in evaluating an OSCE in neurology provides meaningful measurement characteristics of the assessment. Differing from prior work in other medical specialties, the cases students were randomly assigned did not influence their OSCE score; rather, scores varied in expected fashion by domain assessed.

Performance is similar across cases but differs by the particular domain, such that the majority of variance is attributed to the domain. Projections in reliability estimates reveal that students need to participate in 3 OSCE cases in order to increase reliability beyond the 0.70 threshold. This novel use of G theory in evaluating an OSCE in neurology provides meaningful measurement characteristics of the assessment. Differing from prior work in other medical specialties, the cases students were randomly assigned did not influence their OSCE score; rather, scores varied in expected fashion by domain assessed. © 2015 American Academy of Neurology.

Although duodenal lymphangiectasia in individuals without clinical evidence of malabsorption has been reported, the prevalence and clinical significance in this situation are not yet known. The aim of this study was to evaluate the prevalence and clinical significance of incidentally found duodenal lymphangiectasia. A retrospective review of medical records was undertaken for consecutive patients who had undergone diagnostic upper endoscopy between January 2005 and June 2006. A prospective study was then performed in consecutive individuals undergoing routine upper endoscopy for health examination between July 2006 to October 2006. Endoscopic features of duodenal lymphangiectasia were classified into three types: (1) multiple scattered pinpoint white spots; (2) diffuse prominent villi with whitish-discolored tips; and (3) focal small whitish macule or nodule. The histologic grade of duodenal lymphangiectasia was classified according to the depth and severity of lymphatic duct dilatations. Prevalence and clinical data of incidentally found duodenal lymphangiectasia were evaluated in the retrospective and prospective studies. Among 1866 retrospective cases, duodenal lymphangiectasia was endoscopically suspected in 59 cases (3.2%), and histologically confirmed in 35 cases (1.9%). No clinical evidence of malabsorption was noted in the duodenal lymphangiectasia cases. The "scattered pinpoint white spots" type was the most frequently found endoscopic feature (40.0%). Duodenal lymphangiectasia was persistent in seven of 10 individuals who underwent repeat endoscopy after a median of 12 months. Among 134 prospective cases, duodenal lymphangiectasia was histologically confirmed in 12 cases (8.9%). There was no significant clinical difference between groups with and without duodenal lymphangiectasia. Lymphatic duct dilatation was histologically more severe in the "focal small whitish macule or nodule" type than in the other types. Duodenal lymphangiectasia without clinical

Although research often relies on retrospective affect self-reports, little is known about personality's role in retrospective reports and how these converge or deviate from affect reported in the moment. This micro-longitudinal study examines personality (Neuroticism, Extraversion) and emotional salience (peak and recent affect) associations with retrospective-momentary affect report discrepancies over different time frames. Participants were 179 adults aged 20-78 (M = 48.7 years; 73.7% Caucasian/White) who each provided up to 60 concurrent affect reports over 10 days, then retrospectively reported overall intensity of each affective state after 1 day and again after 1-2 months. Multilevel models revealed that individuals retrospectively overreported or underreported various affective states, exhibiting peak associations for high arousal positive and negative affect, recency associations for low arousal positive affect, and distinct personality profiles that strengthened over time. Individuals high in both Extraversion and Neuroticism exaggerated high arousal positive and negative affect and underreported low arousal positive affect, high Extraversion/low Neuroticism individuals exaggerated high arousal positive affect and underreported low arousal positive affect, and low Extraversion/high Neuroticism individuals exaggerated high and low arousal negative affect. This study is the first to identify arousal-specific retrospective affect report discrepancies over time and suggests retrospective reports also reflect personality differences in affective self-knowledge. © 2016 Wiley Periodicals, Inc.

Melasma is an acquired diffuse hypermelanosis characterized by localized, symmetrical, irregular, light-to-dark brown maculae occurring in sun-exposed areas of skin. The aim of this retrospective study was to determine demographics of patients, analysis of etiologic factors, clinical features, efficacy and side effects of available topical treatments due to high incidence of melasma patients. In this study melasma patients in Birecik State Hospital were investigated retrospectively. Between January 2014 and October 2015, 1008 patients had diagnosis of melasma in 49,809 applications of 24,603 different patients who admitted to Dermatology Outpatient Clinics. Of the 1008 patients, 263 had completed 3-month treatment period. These patients did not receive treatment in June, July, August and September. All melasma patients were rural and dealing with agriculture. There was no significant difference between female and male patients in terms of age. Of the 253 female melasma patients, only 2 of them had not child and none of them were using hormone drug. Of the 263 patients with melasma, Fitzpatrick skin type was 3 in 79 (30%) patients, 4 in 184 (70%) patients. Şanliurfa city showed higher fertility rate, sun exposure, and skin type than Turkey as a whole. These predisposing factors may explain higher melasma occurrence in Şanliurfa. Patient information about preventive measures and treatment play important role in treatment of cosmetic condition. The most important measure seems to advise patients about sun-protection especially during pregnancy. PMID:28652905

Frontotemporal dementia and Alzheimer's disease: retrospective differentiation using information from informants.

1995-01-01

The study examined the feasibility of differentiating frontotemporal dementia from Alzheimer's disease on the basis of retrospective historical information obtained from relatives of patients. A structured questionnaire was devised of patients' symptoms, with emphasis on those cognitive and neuropsychiatric features found in earlier prospective clinical studies to distinguish the two conditions. The questionnaire was given to close relatives of deceased patients in whom the diagnosis of non-Alzheimer's frontotemporal degeneration of Alzheimer's disease had been verified at necropsy. The interviewer had no previous contact or knowledge of those patients, nor clinical experience of patients with frontotemporal dementia. The questionnaire elicited a distinct profile of responses for the two diagnostic groups with emphasis on early personality change, unconcern, and socially inappropriate behaviour in frontotemporal dementia and disturbance in memory and topographical orientation prominent in patients with Alzheimer's disease. A scoring system separated out individual patients with frontotemporal dementia from those with Alzheimer's disease. It is concluded that it is possible to obtain useful information about the precise pattern of dementia from informants even many years after the patient's death. The questionnaire provides the foundation of a diagnostic instrument for use in family history studies of dementia. PMID:7608712

2017-02-01

Background: History taking and systematic clinical examination are central techniques of physicians. Medicine in general and surgery in particular frequently require immediate decisions and start of therapies. So far, a standardised surgical system for history taking and clinical examination in teaching has been lacking at our faculty. A consensus of all medical faculties on a standardised system could be a tool to improve the medical teaching and education at our teaching institutions. Methods: The established Anglo-Saxonian system of history taking and clinical examination was adapted to our own clinical needs. Thereafter, this system was sent out to all chairmen of general and visceral surgery departments in German University Hospitals asking for evaluation and improvements. We adapted the system according to the chairmen's comments and suggestions. Since winter semester 2011 this system has been integrated into the clinical course of history taking and examination. It is compulsory for all 5th semester students (first clinical year/graduate course) at the Universitätsmedizin Greifswald. In addition, a video was produced demonstrating all major techniques of clinical examination. This video is available for all students on a password blocked site of the World Wide Web. Results: Altogether, 89 % of all contacted chairmen returned their comments and suggestions for improvements. After implementation of the new system, positive evaluations of students increased significantly from 63.5 to 77.0 % in general and abdominal surgery (p < 0.0001) and from 76.4 to 83.5 % in vascular and thoracic surgery (p < 0.0001). Conclusions: The presented system is a standardised tool of history taking and clinical examination applicable for students as well as qualified surgeons in daily routine work. It has been approved by the majority of the departments of surgery of all German university hospitals. Furthermore, it can be applied by other medical specialties, in

Objectives: In the UK, nine different compounds are available as long-acting antipsychotic injections (LAIs). There are few clinical guidelines for determining which LAIs are most effective in specific patient groups. To measure the clinical effectiveness of LAIs we aimed to determine the now-established concept of antipsychotic discontinuation rates and measure Clinical Global Impression (CGI) outcomes. Method: The population (n was approximately 560,000) was a secondary care NHS adult mental health service in Lanarkshire, Scotland, UK. This was a retrospective, electronic case note search of LAI-naïve patients commenced on paliperidone palmitate (n = 31), risperidone long-acting injection (RLAI) (n = 102) or zuclopenthixol decanoate (n = 105), with an 18-month follow up. Kaplan–Meier survival statistics for discontinuation rates and hospital admission were calculated. CGI severity and improvement scores were retrospectively assigned by the investigating team. Results: Paliperidone palmitate performed less favourably than risperidone long-acting injection (RLAI) or zuclopenthixol decanoate. Paliperidone palmitate had higher discontinuation rates due to any cause, inefficacy and increased hospitalization risk. Paliperidone palmitate had the smallest proportion of patients assigned a clinically desirable CGI-I score of 1 (very much improved) or 2 (much improved). Conclusions: Paliperidone palmitate had less favourable discontinuation and CGI outcomes compared with RLAI and zuclopenthixol decanoate. This could not be adequately explained by patients in the paliperidone group being more chronically or severely unwell, nor by the presence of comorbidities such as alcohol or substance misuse, or by the use of lower mean dosages compared with RLAI or zuclopenthixol decanoate. We considered that prescribers are familiarizing themselves with paliperidone and outcomes may improve over time. PMID:26913175

A presystolic wave (PSW) is commonly seen on Doppler examination of the left ventricular outflow tract (LVOT), but is little studied. We conducted a retrospective study to assess the prevalence of the PSW, correlations with various Doppler parameters, and its clinical significance. Two hundred echocardiograms, 100 with ejection fraction (EF) >55% and 100 with EF <45%, were reviewed. Mitral inflow velocities, septal annular velocities, LVOT, and PSW velocities were measured. Major adverse cardiovascular events (MACE [death, heart failure hospitalization, atrial fibrillation, and stroke]) were compared between those with and without a PSW, in both EF groups. Mean age was 58 ± 15 years; 56% were men and 69% were African-American. PSW prevalence was similar between normal (68%) and reduced EF groups (62%). However, its velocity was less in the low EF group (37 ± 10 vs 48 ± 16 cm/s, p <0.0001). In subjects with normal EF PSW velocity correlated with mitral A velocity (rho = 0.43, p = 0.0003). In subjects with reduced EF the association with A velocity was not significant (rho = 0.22, p = 0.09), but there was a significant association with annular a' velocity (rho = 0.38, p = 0.002). Over a mean follow-up of 1.7 ± 0.3 years, 57 subjects (28%) experienced MACE. Those without a PSW had more MACE (39% vs 23%, p = 0.02); PSW absence remained predictive of MACE after adjustment for multiple variables, especially in patients with reduced EF. In conclusion, PSW is common in the LVOT. Its presence and magnitude are associated with measures of atrial contraction. Its absence is associated with increased rates of adverse events, especially in patients with low EF. Copyright © 2014 Elsevier Inc. All rights reserved.

MR imaging was used to evaluate the integrity of silicone breast implants in 54 women with 108 implants. MR images were interpreted by relatively inexperienced readers who tried to reproduce the experiences reported in the literature. The study examines the interobserver agreement using different diagnostic signs and the influence of experience on interpretation errors. Prospective and retrospective interpretations were compared with surgical findings at the time of explanation. Diagnostic indicators, including the linguine sign, the inverted tear drop sign, the C sign, water droplets mixed with silicone, and extracapsular globules of silicone, were evaluated for diagnostic efficacy and interobserver agreement. The prospective sensitivity and specificity were 87% and 78%, respectively. With the retrospective interpretations, the sensitivity and specificity increased to 93% and 92%, respectively. Most of the prospective false-positive interpretations were due to misinterpreting radial folds as signs of implant rupture. Six implants interpreted retrospectively as false positives had gross amounts of silicone around the implants at surgery but there were no obvious rents in the implant shells. There was fair to excellent interobserver agreement with the individual diagnostic signs except for extracapsular globules of silicone. All of the signs had specificities of greater than 90%. The sensitivities of the individual signs were less than the overall retrospective sensitivity. With experience, the sensitivity improved from 87% to 93% and the specificity improved from 78% to 92%. This study helps substantiate the use of diagnostic signs used by other authors to detect silicone loss from breast implants by MR imaging; however, questions remain as to the clinical role of MR imaging in evaluating implants for silicone loss.

This study aimed to determine the prevalence of hip pain in professional golfers, comparing the lead (left hip in right-handed golfer) and trail hips, and to establish what player characteristics predicted hip symptoms. Male elite professional golf players were invited to complete questionnaires and undergo clinical and MR examinations while attending the Scottish Hydro Challenge 2015. Questionnaires determined player demographics, self-reported hip pain and an International Hip Outcome Tool 12 (iHOT12) score (hip-related quality of life). Clinical examinations determined hip range of motion and the presence of a positive impingement test. MR scans determined the presence of labral pathology and player hip morphology with measures of α angle (cam), acetabular depth (pincer) and femoral neck antetorsion. A total of 109 (70% of tournament field) of players completed questionnaires, 73 (47%) underwent clinical examination and 55 (35%) underwent MR examination. 19.3% of players reported of hip pain. 11.9% of lead and 9.1% of trail hips were painful (p=0.378), iHOT12 scores were lower in the lead (94.1) compared to the trail hip (95.3) (p=0.007). Stepwise multiple linear regression modelling was able to predict 20.7% of the variance in iHOT12 scores with mean α angles between 12 and 3 o'clock, and increasing age-significant variables (R(2)=0.207, p<0.001; β=-0.502, p<0.001 and β=-0.399, p=0.031, respectively). 19.3% of male professional golfers reported hip pain. The presence of an increasing α angle and increasing age were significant predictors of reduced hip-related quality of life. Published by the BMJ Publishing Group Limited.

To determine sensitivity and specificity of cytologic examination used in a clinical setting. Retrospective study. 216 dogs, 44 cats, 4 horses, 2 ferrets, 1 llama, 1 rat, and 1 mouse. Records were reviewed of cases in which a cytologic diagnosis was followed by a surgical biopsy or postmortem examination within 3 days with subsequent histopathologic diagnosis. Diagnoses were compared for agreement at various levels, including complete agreement, partial agreement, no agreement, or no comparison possible because of insufficient or incorrect cytologic specimen. Levels of agreement were compared for different categories of lesions, including neoplastic, inflammatory, dysplastic-hyperplastic-other, and normal tissue. Additionally, levels of agreement for neoplastic lesions were categorized with regard to cell type, degree of malignancy, and location. Sensitivity and specificity of cytologic examination were calculated. At the level of general agreement (complete and partial agreement), the sensitivity of cytologic examination ranged from 33.3 to 66.1%, depending on the location of the lesion. Cytologic examination was most accurate when used to diagnose cutaneous and subcutaneous lesions and least accurate for diagnosis of liver lesions. Cytologic examination was most effective in diagnosis of neoplastic disease and least effective in diagnosis of dysplastic or hyperplastic conditions. Cytologic examination is a valuable diagnostic tool, although our results indicated lower accuracy than previously reported. False-negative results (missing a diagnosis) were far more common than false-positive results (categorizing a healthy animal as diseased): therefore, if the clinical index of suspicion is high, cytologic examination should be repeated or another technique should be selected to rule out the suspected condition.

Shoulder pain in primary care: diagnostic accuracy of clinical examination tests for non-traumatic acromioclavicular joint pain

PubMed Central

2013-01-01

Background Despite numerous methodological flaws in previous study designs and the lack of validation in primary care populations, clinical tests for identifying acromioclavicular joint (ACJ) pain are widely utilised without concern for such issues. The aim of this study was to estimate the diagnostic accuracy of traditional ACJ tests and to compare their accuracy with other clinical examination features for identifying a predominant ACJ pain source in a primary care cohort. Methods Consecutive patients with shoulder pain were recruited prospectively from primary health care clinics. Following a standardised clinical examination and diagnostic injection into the subacromial bursa, all participants received a fluoroscopically guided diagnostic block of 1% lidocaine hydrochloride (XylocaineTM) into the ACJ. Diagnostic accuracy statistics including sensitivity, specificity, predictive values, positive and negative likelihood ratios (LR+ and LR-) were calculated for traditional ACJ tests (Active Compression/O’Brien’s test, cross-body adduction, localised ACJ tenderness and Hawkins-Kennedy test), and for individual and combinations of clinical examination variables that were associated with a positive anaesthetic response (PAR) (P≤0.05) defined as 80% or more reduction in post-injection pain intensity during provocative clinical tests. Results Twenty two of 153 participants (14%) reported an 80% PAR. None of the traditional ACJ tests were associated with an 80% PAR (P<0.05) and combinations of traditional tests were not able to discriminate between a PAR and a negative anaesthetic response (AUC 0.507; 95% CI: 0.366, 0.647; P>0.05). Five clinical examination variables (repetitive mechanism of pain onset, no referred pain below the elbow, thickened or swollen ACJ, no symptom provocation during passive glenohumeral abduction and external rotation) were associated with an 80% PAR (P<0.05) and demonstrated an ability to accurately discriminate between an PAR and NAR

OBJECTIVE To compare clinical signs and outcomes between dogs with presumptive ischemic myelopathy and dogs with presumptive acute noncompressive nucleus pulposus extrusion (ANNPE). DESIGN Retrospective study. ANIMALS 51 dogs with ischemic myelopathy and 42 dogs with ANNPE examined at 1 referral hospital. PROCEDURES Medical records and MRI sequences were reviewed for dogs with a presumptive antemortem diagnosis of ischemic myelopathy or ANNPE. Information regarding signalment, clinical signs at initial examination, and short-term outcome was retrospectively retrieved from patient records. Long-term outcome information was obtained by telephone communication with referring or primary-care veterinarians and owners. RESULTS Compared with the hospital population, English Staffordshire Bull Terriers and Border Collies were overrepresented in the ischemic myelopathy and ANNPE groups, respectively. Dogs with ANNPE were significantly older at disease onset and were more likely to have a history of vocalization at onset of clinical signs, have spinal hyperesthesia during initial examination, have a lesion at C1-C5 spinal cord segments, and be ambulatory at hospital discharge, compared with dogs with ischemic myelopathy. Dogs with ischemic myelopathy were more likely to have a lesion at L4-S3 spinal cord segments and have long-term fecal incontinence, compared with dogs with ANNPE. However, long-term quality of life and outcome did not differ between dogs with ischemic myelopathy and dogs with ANNPE. CONCLUSIONS AND CLINICAL RELEVANCE Results revealed differences in clinical signs at initial examination between dogs with ischemic myelopathy and dogs with ANNPE that may aid clinicians in differentiating the 2 conditions.

To examine the epidemiology of referrals to a specialist neurotrauma clinic and explore and highlight implications for clinical practice and service development for persons with head injury/traumatic brain injury (HI/TBI). A retrospective population-based cohort study of all referrals to a specialist neurotrauma clinic over a 9-year period. Data from a specialist head injury database (which included all persons presenting to hospital with traumatic brain injury) were analysed. In total, 1235 new patients of all ages, severities of injury, both admitted and non-admitted were referred. Referrals have increased due to successful integration with new service developments and resulting optimization of resources. Data gathered from the cohort gives increased understanding of the characteristics and numbers of patients requiring rehabilitation and adds to the evidence-base. Integration with new and complementary service developments has optimized the function/aims of the clinic and enhanced its role in terms of patient service and outcome and as a research resource. The model provides principles which may be applied to planning, organizing and providing follow-up/rehabilitation services for HI/TBI.

To determine whether attendance at a specialised multidisciplinary antenatal clinic for women with class III obesity (BMI >40 kg/m 2 ) is associated with improved clinical outcomes compared with standard antenatal care. Retrospective cohort study using routinely collected data from electronic patient record. Community and hospital based antenatal care. Women with a singleton pregnancy with class III obesity booked for antenatal care and delivered in one of two hospitals in NHS Lothian, Scotland, UK between 2008 and 2014. Maternal and offspring outcomes were compared in women who attended a specialised obesity clinic (n=511) compared with standard antenatal care (n=502). Included stillbirth, low birth weight, gestational diabetes, induction of labour and caesarean section. Compared with standard care, women receiving specialist care were less likely to have a stillbirth (OR 0.12, 95% CI 0.06 to 0.97) and a low birthweight baby (OR 0.57, 95% CI 0.33 to 0.99) and more likely to be screened for (100% vs 73.6%; p<0.001) and diagnosed with (26.0% vs 12.5%; p<0.001) gestational diabetes, to require induction of labour (38.4% vs 29.9%; p=0.009), an elective (20.3% vs 17.7%; p<0.001) and emergency (23.9% vs 20.3%; p<0.001) caesarean section and attend antenatal triage one or more times during pregnancy (77.7% vs 53.1%; p<0.001). Women attending the specialist clinic had a higher BMI (44.5 kg/m 2 (4.3) vs 43.2 kg/m 2 (3.1); p<0.001) and were more likely to be nulliparous (46.0% vs 24.9%; p<0.001). There were no other differences in maternal demographic or maternal and offspring outcomes between groups. Attendance at a specialised antenatal clinic for obesity is associated with reduced rates of stillbirth and low birth weight and improved detection of gestational diabetes. The improvement in clinical outcomes is associated with an increase in healthcare attendance to obstetric triage and clinical interventions including induction of labour and caesarean section. �

Adjusting to symptom flares, treatment regimens, and side effects places youth with inflammatory bowel disease (IBD) at increased risk for emotional and behavioral problems and adverse disease outcomes. Implementation of psychosocial screening into clinical practice remains a challenge. This study examines the clinical utility of health-related quality of life (HRQOL) screening in predicting disease outcome and healthcare utilization. One hundred twelve youth of 7 to 18 years diagnosed with IBD and their parents. Youth completed standardized measures of HRQOL and depression. Parents completed a proxy report of HRQOL. Pediatric gastroenterologists provided the Physician Global Assessment. Families were recruited from a pediatric gastroenterology clinic. Retrospective chart reviews examined disease outcome and healthcare utilization for 12 months after baseline measurement. Linear regressions, controlling for demographic and disease parameters, revealed that baseline measurement of youth and parent proxy-reported HRQOL predicted the number of IBD-related hospital admissions, gastroenterology clinic visits, emergency department visits, psychology clinic visits, telephone contacts, and pain management referrals over the next 12 months. Disease outcome was not significant. Lower HRQOL was predictive of increased healthcare utilization among youth with IBD. Regular HRQOL screening may be the impetus to providing better case management and allocating resources based on ongoing care needs and costs. Proactive interventions focused on patients with poor HRQOL may be an efficient approach to saving on healthcare costs and resource utilization.

Aim To assess the frequency and forms of pulmonary tuberculosis at autopsy in a high-traffic hospital in the capital city of a country with a low tuberculosis incidence. Methods We performed a retrospective search of autopsy data from the period 2000 to 2009 at Sestre Milosrdnice University Hospital Center, Zagreb, Croatia. We also examined patients’ records and histological slides. Results Of 3479 autopsies, we identified 61 tuberculosis cases, corresponding to a frequency of 1.8%. Active tuberculosis was found in 33 cases (54%), 23 of which (70%) were male. Of the 33 active cases, 25 (76%) were clinically unrecognized and 19 (76%) of these were male. Conclusion Clinically undiagnosed tuberculosis accounted for a substantial proportion of active tuberculosis cases diagnosed at autopsy. Autopsy data may be an important complement to epidemiological data on tuberculosis frequency. PMID:22351578

Little is known about the clinical characteristics of patients with dementia receiving electroconvulsive therapy (ECT) for the treatment of behavioral symptoms. This study examined the demographic and clinical profile of patients with dementia receiving ECT in China. This was a retrospective, case-control study. The sample was composed of 23 patients with dementia treated with ECT and 71 sex- and age-matched controls treated for a period of 8 years (2007-2014) at the National Clinical Research Centre of Mental Disorders, China. Sociodemographic and clinical data were collected from the electronic chart management system. Multiple logistic regression analysis revealed that ECT was independently associated with high risk for suicide at admission. The recorded indications for ECT included both high risk for suicide and aggressive behavior. Most patients responded to ECT satisfactorily (56.5%) or partially (34.8%) with only mild-moderate transient memory impairment (30.4%). Although this is a preliminary study limited by the retrospective design and small sample size, findings suggest that ECT is an effective and safe therapeutic intervention to reduce the risk for suicide and aggressive behavior in dementia.

To retrospectively compare and contrast the clinical presentation, diagnostic findings and survival in Boxer dogs with cardiomyopathy, with or without left ventricular (LV) systolic failure. Medical records of Boxers referred between 1993 and 2008 in which a diagnosis of ventricular arrhythmias and/or cardiomyopathy was made, were reviewed. Dogs were divided into two groups according to their left ventricular (LV) systolic diameter, group A normal (20 dogs) or group B dilated (59 dogs). Dogs in group A had a better outcome than dogs in group B (median survival time of 124 and 17 weeks respectively, p < 0.001). In group B, dogs with a history of collapse had a worse outcome (median survival time of 10 weeks) compared with dogs not showing collapse (median survival time 24 weeks) (p = 0.031). The majority of dogs, in this UK study, presented with the myocardial dysfunction form of the disease, with LV dilation and congestive heart failure signs. The prognosis was worse in dogs with LV dilation compared to dogs with a normal LV and ventricular arrhythmias. In the Boxers with LV dilation, dogs with collapse had a worse prognosis than those without. Copyright © 2011 Elsevier B.V. All rights reserved.

Leading scientific and organizational prerequisites for the feasibility of clinical examination of the entire child population of the Russian Federation to the dentist is, above all, the high prevalence and intensity of dental diseases in children of all ages. As a result of many years of research and follow-up of children of preschool and school age we have proved the need to distinguish a group of children with zero activity of dental caries. The referring criteria are determined according to the results of comprehensive clinical and laboratory examination in order to determine the degree of risk of dental caries and individual caries resistance. The age-specific risk group is settled by "Stop caries" software. In order to optimize the preventive activities children are divided in 5 groups for routine preventive dental care. Unfortunately the efforts of modern dental services aimed at eliminating the consequences of caries process by filling cavities. Individualized preventive approach will increase the effectiveness of preventive measures and save public funds allocated in the amount of compulsory health insurance for pediatric dentistry.

The aims of this study were to determine the prevalence of hypophosphatemia and to discuss the clinical implications of hypophosphatemia in critically ill children. A retrospective review of the medical records of children admitted to the pediatric intensive care unit from December 2006 to December 2007 was conducted. In 60.2% (n = 71) of the patients, any serum phosphorous level at admission and at the third day or seventh day after admission to pediatric intensive care unit was in hypophosphatemic range. Sepsis was present in 22.9% (n = 27) of the children studied and was associated with hypophosphatemia (P = .02). Hypophosphatemia was also associated with use of furosemide (P = .04), use of steroid (P = .04), use of β(2) agonist (P = .026), and use of an H(2) blocker (P = .004). There was a significant association between hypophosphatemia and the rate to attain target caloric requirements by enteral route (P = .007). The median time to attain target caloric requirements by enteral route was 2.9 ± 1.9 (0.2-10) days in the normophosphatemic group and 4.4 ± 2.8 (0.3-12) days in the hypophosphatemic group. In the multiple regression model, solely the rate to attain the target caloric requirements by enteral route demonstrated independent association with hypophosphatemia (P = .006; β = .27; 95% confidence interval, 0.02-0.09). Significant association was found between hypophosphatemia and the duration of mechanical ventilation and between hypophosphatemia and pediatric intensive care unit length of stay (P = .02 and P = .001, respectively). Critically ill pediatric patients are prone to hypophosphatemia, especially if they cannot be fed early by enteral route. Hypophosphatemia is associated with an increased duration of mechanical ventilation and increased length of stay in the pediatric intensive care unit, suggesting that active repletion might improve these parameters.

This retrospective hospital-based study reviewed and evaluated the outcome of patients with oral squamous cell carcinoma (OSCC) with the aim of identifying factors affecting the clinical course and survival rate. Patients with a follow-up of at least 12 months were included. The data collected were statistically analyzed for the presence of factors valuable for prognosis; survival curves were processed in accordance with the Kaplan-Meier method. Differences in the expression of variables in different grading levels were investigated. Cox's proportional hazard model for Z(i) covariates (grading, age, T, N) also was calculated. Mean patient age was 67.7 years in women (n = 152) and 62.4 years in men (n = 182). A total of 98 patients were identified with Broder's/World Health Organization grade 1 histology, 176 with grade 2, and 55 with grade 3; 5 patients were identified as grade 4 (carcinoma in situ). Gender and risk factors seemed to be unrelated to prognosis, whereas a significant increase in mortality was seen in patients over age 70. Histological grading, tumor size, and neck involvement were related, as independent factors, in predicting survival in patients with OSCC (QM-H > 3.9). Gender, age, and risk factors had no statistical relationship with cancer histological differentiation. Our analysis reveals a statistically significant relationship among histological Broder's grading of malignancy, tumor size, locoregional involvement, and survival rates, underscoring the utility of tumor differentiation in predicting the clinical course and outcome of OSCC.

A protected block curriculum (PBC) with postcurriculum examinations for all surgical residents has been provided to assure coverage of core curricular topics. Biannual assessment of resident competency will soon be required by the Next Accreditation System. To identify opportunities for early medical knowledge assessment and interventions, we examined whether performance in postcurriculum multiple-choice examinations (PCEs) is predictive of performance in the American Board of Surgery In-Training Examination (ABSITE) and clinical service competency assessments. Retrospective single-institutional education research study. Academic general surgery residency program. A total of 49 surgical residents. Data for PGY1 and PGY2 residents participating in the 2008 to 2012 PBC are included. Each resident completed 6 PCEs during each year. The results of 6 examinations were correlated to percentage-correct ABSITE scores and clinical assessments based on the 6 Accreditation Council for Graduate Medical Education core competencies. Individual ABSITE performance was compared between PGY1 and PGY2. Statistical analysis included multivariate linear regression and bivariate Pearson correlations. A total of 49 residents completed the PGY1 PBC and 36 completed the PGY2 curriculum. Linear regression analysis of percentage-correct ABSITE and PCE scores demonstrated a statistically significant correlation between the PGY1 PCE 1 score and the subsequent PGY1 ABSITE score (p = 0.037, β = 0.299). Similarly, the PGY2 PCE 1 score predicted performance in the PGY2 ABSITE (p = 0.015, β = 0.383). The ABSITE scores correlated between PGY1 and PGY2 with statistical significance, r = 0.675, p = 0.001. Performance on the 6 Accreditation Council for Graduate Medical Education core competencies correlated between PGY1 and PGY2, r = 0.729, p = 0.001, but did not correlate with PCE scores during either years. Within a mature PBC, early performance in a PGY1 and PGY2 PCE is predictive of performance
