    Bacillus Calmette-Guèrin (BCG) is commonly used not only as an infant vaccination, but also as a treatment of and prophylaxis to prevent recurrence in the management of non-muscle-invasive bladder cancer. However, the use of "live" BCG is sometimes complicated by associated infection. We present a case study of a 77-year-old man who developed bilateral renal masses after intravesical BCG therapy was initiated in November 2013, following transurethral resection of non-muscle-invasive bladder cancer. After four courses of BCG (Japan strain, 80 mg per treatment) instillations, a computed tomography examination for febrile episodes showed multiple bilateral renal masses, accompanied by a histological finding of a granulomatous reaction. An acid fast bacterium was cultured from only urine among blood, urine, and microscopic samples. Using the cultured strain, BCG infection was confirmed by the specific gene deletion pattern based on allele-specific polymerase chain reaction analysis. Anti-tuberculosis treatment, including isoniazid (300 mg/day), rifampicin (600 mg/day), and ethambutol (1,000 mg/day), was started for the BCG-related renal granuloma in February 2014. After 3 months, antibiotic therapy was discontinued owing to severe appetite loss, though the masses remained solid. No rapid growth has been detected after anti-BCG therapy. Intravesical BCG therapy is recommended worldwide as one of standard treatments for non-muscle-invasive bladder cancer. We should closely observe patients undergoing this approach for emerging BCG complications.

    The review is dedicated to ultrasonography of the upper urinary tract in patients with nephrolithiasis. Ultrasonographic semiotics of urolithiasis, the ability of unlrasonography to detect nephrolithiasis, and methods of the optimization of these diagnostic techniques in patients with upper urinary tract calculi are covered. The author discusses difficulties that may be faced while differentiating between nephrolithiasis and such conditions as spongious kidney, nephrocalcinosis, calcification of renal papillae, cysts, tumors, and vascular walls, as well as other kinds of renal calcification, associated with ultrasonographic acoustic path phenomenon. The advantages and disadvantages of ultrasonography in cases of X-ray urolithiasis are evaluated in the paper. The article describes hardships in ultrasound visualization of ureteral calculi causing acute upper urinary tract obstruction, and the ways of getting over them.

    In a two year period from March 1983, 157 patients with upper urinary tract stones were managed primarily by endoscopy. Of 90 patients with renal stones, extraction was achieved in 91% of patients with complete extraction in 76%. Of the remaining patients with ureteric stones, successful extraction was achieved in 75%. Ten patients required open surgery which was for failed extraction in 9. Morbidity is low with a mean hospital stay of 4.7 days for patients with kidney stones, and of 3.7 days for patients undergoing extraction of ureteric stones. Images Fig. 2 PMID:3954313

    Even though urothelial cancer may occur anywhere in the urinary tract, it is most commonly found in the urinary bladder. Due to its higher incidence, this disease is studied in the bladder much more frequently than in the upper urinary tract. The question that arises is, to what extent can concepts and treatment paradigms derived from lower tract disease be applied to urothelial carcinoma of the upper urinary tract? This review aims at providing an overview of established care concepts in urothelial carcinoma of the bladder and applicability of these findings to tumors of the upper urinary tract.

    The authors report a case with upper eyelid retraction caused by topical bimatoprost therapy. Topical bimatoprost 0.03% was administered to a 69-year-old woman with bilateral normal-tension glaucoma. It was first administered to the left eye, and 3 weeks later, therapy on the right side of the eye was initiated. One week after the initiation of therapy on the right side, right upper eyelid retraction occurred, and 63 days after starting treatment on the left side (42 days after initiation on the right side), conspicuous bilateral upper eyelid retraction was observed. Bimatoprost instillation was then stopped and the medication was switched to latanoprost 0.005%. Upper eyelid retraction was reversed to normal levels approximately 1 week after cessation of bimatoprost therapy. In conclusion, a rare case of upper eyelid retraction caused by topical bimatoprost therapy, which was reversed after discontinuation of the medication, is reported.

    Patients undergoing urinary diversion are at high risk for developing stone disease due to the metabolic and structural features intrinsic to the creation of a urinary reservoir. The utilization of shockwave lithotripsy as well as antegrade and retrograde endoscopic techniques in appropriately selected patients affords a relatively safe and effective means of stone removal. This review focuses on the etiology of stone formation in patients with urinary diversion and examines the most relevant and current reports on expulsive techniques and their associated outcomes for patients within this population who develop upper urinary tract calculi.

  7. Bilateral and multiple cavitation sounds during upper cervical thrust manipulation

    PubMed Central

    2013-01-01

    Background The popping produced during high-velocity, low-amplitude (HVLA) thrust manipulation is a common sound; however to our knowledge, no study has previously investigated the location of cavitation sounds during manipulation of the upper cervical spine. The primary purpose was to determine which side of the spine cavitates during C1-2 rotatory HVLA thrust manipulation. Secondary aims were to calculate the average number of pops, the duration of upper cervical thrust manipulation, and the duration of a single cavitation. Methods Nineteen asymptomatic participants received two upper cervical thrust manipulations targeting the right and left C1-2 articulation, respectively. Skin mounted microphones were secured bilaterally over the transverse process of C1, and sound wave signals were recorded. Identification of the side, duration, and number of popping sounds were determined by simultaneous analysis of spectrograms with audio feedback using custom software developed in Matlab. Results Bilateral popping sounds were detected in 34 (91.9%) of 37 manipulations while unilateral popping sounds were detected in just 3 (8.1%) manipulations; that is, cavitation was significantly (P < 0.001) more likely to occur bilaterally than unilaterally. Of the 132 total cavitations, 72 occurred ipsilateral and 60 occurred contralateral to the targeted C1-2 articulation. In other words, cavitation was no more likely to occur on the ipsilateral than the contralateral side (P = 0.294). The mean number of pops per C1-2 rotatory HVLA thrust manipulation was 3.57 (95% CI: 3.19, 3.94) and the mean number of pops per subject following both right and left C1-2 thrust manipulations was 6.95 (95% CI: 6.11, 7.79). The mean duration of a single audible pop was 5.66 ms (95% CI: 5.36, 5.96) and the mean duration of a single manipulation was 96.95 ms (95% CI: 57.20, 136.71). Conclusions Cavitation was significantly more likely to occur bilaterally than unilaterally during upper cervical HVLA

    Upper urinary malignancies are rare tumors whose diagnosis sometimes represents a difficult dilemma. In selected cases, it is possible to treat the tumor with laser irradiation. This approach is reserved to low-stage low-grade tumors, a tumor in a solitary kidney, bilateral syncroneous disease or patients with deterioration of renal function. Thirty one patients suspected to have malignancies, as they presented upper tract filling defects at IVP, underwent uretero-pyeloscopy to confirm the diagnosis. Twenty patients with upper urinary tract urothelial tumors were treated with Nd:YAG laser irradiation. Before the procedure, the ureter and the pelvis were accessed by 0.038 inch guide-wire or 4 French ureteral catheter. A power of 25 - 30 watts/3 seconds was carried out for the laser irradiation of the tumor and of the base. Sometime after the procedure a ureter single J catheter was left indwelling for 48 hours. In the follow-up the patients had endoscopic surveillance every three months. Actually 12 patients are tumor-free after 3 - 36 months. Eight patients had a recurrence after the first treatment and they underwent new laser irradiation. All the recurrences were in other sites of the upper urinary tract and seemed to be related to tumor grade. In conclusion, conservative endourological ureteropyeloscopy coupled with Nd:YAG laser irradiation should be considered a useful treatment in selected patients.

    Nephrogenic diabetes insipidus (NDI) is a condition resulting from the kidney's impaired response to circulating antidiuretic hormone (ADH), leading to polydipsia and polyuria. Urinary tract dilatation caused by NDI is a rare situation. Here, we report a case of congenital NDI presented with bilateral hydronephrosis.A 15-year-old boy complaining a history of intermittent fever was admitted to Peking Union Medical College Hospital. He voided 10 to 15 L of urine daily. Radiographic examination revealed severe dilatation of bilateral renal pelvis, ureter, and bladder. Urinalysis shows hyposthenuria.He was diagnosed NDI since born. Transient insertion of a urethral catheter helped to relieve fever. Medical therapy of hydrochlorothiazide and amiloride was prescribed and effective.Dilatation of urinary tract caused by diabetes insipidus is rare, but may be present in severe condition. Therefore, it is crucial for clinicians to perform early treatment to avoid impairment of renal function. PMID:27258490

    Upper urinary tract urothelial cell carcinomas (UUT-UCs) are uncommon and are defined as urothelial carcinoma involving the urinary tract from the renal calyces, renal pelvis to the distal ureter. One well-known an peculiar histopathological finding in UUT-UC is urothelial carcinoma with intratubular spread (retrograde spread within renal tubules). However, this special feature has not been systematically studied. We therefore collected a total of 53 consecutive cases of upper urinary tract urothelial carcinomas (UUT-UCs), and studied the clinical and pathological features of intratubular spread (IS). A cocktail stain comprised of antibodies PAX8 and p63 together with PAS was validated and employed to facilitate the study of intratubular spread. Seventeen cases (31.5%) showed intratubular spread demonstrated by either H&E stain and/or the cocktail stain. All of the 17 cases wit intratubular spread had tumor involvement of the renal calyx; the majority of these (14/17, 82.4%) were high grade urothelial carcinoma and the remainder (3/17, 17.6%) were low grade. 4 of 17cases (23.5%) were non-invasive. We classified intratubular spread into 4 different types, based on histopathological patterns: pagetoid, typical, florid, and secondary invasion from intratubular spread. In conclusion, study shows intratubular spread of urothelial carcinoma is fairly common phenomenon in UUT-UC and is associated with a variety of clinical-pathological features. High grade UUT-UC tends to have more extensive intratubular spread and secondary invasion into renal parenchyma. Distinct morphological characteristics as well as the staining pattern from a unique cocktail stain help to identify and evaluate intratubular spread of urothelial carcinoma. Recognizing these different types of intratubular spreading (IS) is crucial for accurate staging of some upper urinary tract urothelial carcinomas (UUT-UCs). PMID:25374911

    The surgical management of urolithiasis is an ever-changing discipline that presents unique challenges to the urologist. This article reviews the current minimally invasive treatment options for upper urinary tract urolithiasis. First it examines several factors that influence stone-free rates, including Hounsfield units of calculi, obesity, and lower pole factors. Surgical management of ureteral calculi is reviewed along with a discussion of stone management in high-risk patients including those who are pregnant. Surgical technique of shockwave lithotripsy, ureteroscopy, percutaneous nephrolithotomy, and laparoscopy is discussed in depth, with attention paid to possible variations in technique.

    Extracorporeal shock wave lithotripsy (ESWL) currently is performed in selected urologic centers to treat over 80 per cent of patients with symptomatic upper urinary tract calculi. This noninvasive technique utilizing shockwaves to disintegrate stones into sand-sized particles allows the patient to pass the particles with spontaneous urination and replaces most surgery or percutaneous endoscopy for stone removal. However, stone-free success rates must be individualized depending on stone position, stone size, and composition. Lithotripsy of renal stones prior to migration and proximal ureteral stones early in their symptomatic course may alter significantly the incidence of distal ureteral calculi requiring hospitalization, cystoscopy, or ureteroscopy.

    The experiments performed in this PhD thesis were conducted at the Institute of Experimental Surgery, Skejby Hospital, Aarhus, Denmark and at the Laboratory of Animal Science, Odense University Hospital, Denmark. The thesis is based on 3 peer review articles published in international journals and a review. Diagnostic or therapeutic endoscopic upper urinary tract procedures are usually characterised as minimal invasive procedures and associated with a low complication rate. Most often fever or pain are seen and sometimes septicaemia. However, mucosa lesion or even ureteric ruptures are known complications. Research has suggested that high renal pelvic pressures generated during these procedures, might contribute to per-/postoperative complications seen, and even possible renal parenchymal damage. Nevertheless, local administration (endoluminal) of a relaxant drug has not previously been tried in order to lower renal pelvic pressure. The purposes of this thesis were to examine the effect of local administration (endoluminal) of the nonspecific β-adrenergic agonist ISOproterenol (ISO) on: 1) The normal pressure flow relation in porcine ureter, 2) The effect of endoluminal ISO perfusion during flexible ureterorenoscopy, 3) The pressure flow relation during semirigid ureterorenoscopy and 4) The cardiovascular system. Among other receptor-types β-adrenergic receptor are located in the upper urinary tract and the activation thereof mediates smooth muscle relaxation. We have shown - in an animal experimental model - that ISO added to the irrigation fluid had significant impact on the renal pelvic pressures generated during upper urinary tract endoscopy. ISO significantly and dose dependently reduced the normal pressure flow relations by approximately 80% without concomitant cardiovascular side effects or measurable plasma levels of ISO. During flexible ureterorenoscopy 0.1 µg/ml ISO added to the irrigation fluid significantly reduced renal pelvic pressure during

    The treatment results and survivorship of patients with upper urinary tract tumors (UUTT) are largely dependent on the early diagnosis of the lesions. Twenty-eight patients presenting UUTT are studied and treated in the Clinic of Urology over the period 1987 through 1995. The diagnostic protocol includes both standard radiographic and cytological techniques, and endoscopic methods allowing for visualization and histopathological characterization of the neoplasm. The diagnostic relevance of the various methods and their efficacy are assayed, with emphasis on the necessity of their use in the differential diagnosis. The diagnostic approach described contributes to mace precise early diagnosis with preoperative determination of the degree of tumor differentiation which has an essential practical bearing on the choice of operative procedure and prognosis of the disease.

    This study was designed to compare baseline data and clinical outcome between patients with prostate enlargement/benign prostatic hyperplasia (PE/BPH) who underwent unilateral and bilateral prostatic arterial embolization (PAE) for the relief of lower urinary tract symptoms (LUTS). This single-center, ambispective cohort study compared 122 consecutive patients (mean age 66.7 years) with unilateral versus bilateral PAE from March 2009 to December 2011. Selective PAE was performed with 100- and 200-{mu}m nonspherical polyvinyl alcohol (PVA) particles by a unilateral femoral approach. Bilateral PAE was performed in 103 (84.4 %) patients (group A). The remaining 19 (15.6 %) patients underwent unilateral PAE (group B). Mean follow-up time was 6.7 months in group A and 7.3 months in group B. Mean prostate volume, PSA, International prostate symptom score/quality of life (IPSS/QoL) and post-void residual volume (PVR) reduction, and peak flow rate (Qmax) improvement were 19.4 mL, 1.68 ng/mL, 11.8/2.0 points, 32.9 mL, and 3.9 mL/s in group A and 11.5 mL, 1.98 ng/mL, 8.9/1.4 points, 53.8 mL, and 4.58 mL/s in group B. Poor clinical outcome was observed in 24.3 % of patients from group A and 47.4 % from group B (p = 0.04). PAE is a safe and effective technique that can induce 48 % improvement in the IPSS score and a prostate volume reduction of 19 %, with good clinical outcome in up to 75 % of treated patients. Bilateral PAE seems to lead to better clinical results; however, up to 50 % of patients after unilateral PAE may have a good clinical outcome.

    [Purpose] This study investigated the therapeutic effects of virtual reality-based bilateral upper-extremity training on brain activity in patients with stroke. [Subjects and Methods] Eighteen chronic stroke patients were divided into two groups: the virtual reality-based bilateral upper-extremity training group (n = 10) and the bilateral upper-limb training group (n = 8). The virtual reality-based bilateral upper-extremity training group performed bilateral upper-extremity exercises in a virtual reality environment, while the bilateral upper-limb training group performed only bilateral upper-extremity exercise. All training was conducted 30 minutes per day, three times per week for six weeks, followed by brain activity evaluation. [Results] Electroencephalography showed significant increases in concentration in the frontopolar 2 and frontal 4 areas, and significant increases in brain activity in the frontopolar 1 and frontal 3 areas in the virtual reality-based bilateral upper-extremity training group. [Conclusion] Virtual reality-based bilateral upper-extremity training can improve the brain activity of stroke patients. Thus, virtual reality-based bilateral upper-extremity training is feasible and beneficial for improving brain activation in stroke patients.

Potentially relevant literature was searched in the PubMed, Web of Science, and Google Scholar databases from 1990 onwards. Devices were categorized as mechanical or robotic (according to the PubMed MeSH term of robotics). Results. In total, 6 mechanical and 14 robotic bilateral upper limb training devices were evaluated in terms of mechanical and electromechanical characteristics, supported movement patterns, targeted part and active involvement of the upper limb, training protocols, outcomes of clinical trials, and commercial availability. Conclusion. Initial clinical results are not yet of such caliber that the devices in question and the concepts on which they are based are firmly established. However, the clinical outcomes do not rule out the possibility that the concept of bilateral training and the accompanied devices may provide a useful extension of currently available forms of therapy. To actually demonstrate their (surplus) value, more research with adequate experimental, dose-matched designs, and sufficient statistical power are required. PMID:23251833

    Endoluminal ultrasound scanning (EUS) of the upper urinary tracts (UUT) with intracavitary catheter sensor was performed in 15 patients (7 men and 8 women) aged 21 to 61 years. In 8 patients EUS was diagnostic (in one patient it was made twice, in 2 cases--in combination with ureteroscopy and biopsy), in 7 patients it was a diagnostic stage of the following surgical intervention, in 6--in combination with roentgenoendoscopic correction of strictures of the ureteropelvic segment (UPS) and in 1--in combination with transurethral pyelolithotripsy. A total of 16 procedures were made: 15 transurethral and 1--percutaneous. Endoluminal ultrasonography was conducted not only of the whole ureter but also of renal calycopelvic system (RAPS) which presented endosonographic semiotics of UUT. EUS has diagnosed urate concrement in 4 cases, "cross" vessels which narrowed UPS in 3 cases with late hydronephrotic transformation. In one patient EUS was carried out in combination with ureteroscopy and biopsy as a control examination 6 and 18 months after transurethral endoresection of ureteral tumor. In 6 patients with UPS strictures EUS was made for diagnosis of suspected cross vessels before endopyelotomy. No complications during EUS were encountered. Pilot experience with intracavitary ultrasonography of the UUT shows its high diagnostic potential and clinical value. This technique details inner structures of the ureter and RAPS with adjacent tissues due to minimal distance between the sensor and studied object.

    This study aimed to investigate associations between primary urinary incontinence and development of upper urinary tract stones in a nationwide population in Taiwan. Data of 1,777 adults with primary urinary incontinence and 26,655 controls (groups A, B, and C) without urinary incontinence at study inception were retrieved from the National Health Insurance System database in Taiwan and were analyzed retrospectively. No enrolled subjects had previous diagnosis of upper urinary tract stones or spinal cord injury. All subjects were followed through end of 2009, with a minimum follow-up of 8 years. A greater percentage of study subjects (334/1777, 18.8%) developed upper urinary tract stones than that of control groups A (865/8885, 9.7%) and B (888/8885, 10%), and C (930/8885, 10.5%) (all p-values < 0.0001). Urinary incontinence was associated with significantly increased risk of developing urinary tract stones (HR 1.99, 95% CI, 1.70–2.34, p < 0.001). Age and metabolic syndrome status were both associated with developing upper urinary tract stones (both p-values < 0.0001). After adjusting for metabolic syndrome, regression analysis showed that urinary incontinence was still associated with a significantly increased risk of developing upper urinary tract stones (HR 1.99, 95% CI = 1.76–2.26, p < 0.0001). Long-term follow-up of Taiwanese patients with primary urinary incontinence suggests that urinary incontinence is associated with a significantly increased risk of developing upper urinary tract stones. Study findings suggest that physicians treating patients with urinary incontinence should give attention to early detection of upper urinary tract stones. PMID:27536881

    Background The use of both upper extremities (UE) is necessary for the completion of many everyday tasks. Few clinical assessments measure the abilities of the UEs to work together; rather, they assess unilateral function and compare it between affected and unaffected UEs. Furthermore, clinical assessments are unable to measure function that occurs in the real-world, outside the clinic. This study examines the validity of an innovative approach to assess real-world bilateral UE activity using accelerometry. Methods Seventy-four neurologically intact adults completed ten tasks (donning/doffing shoes, grooming, stacking boxes, cutting playdough, folding towels, writing, unilateral sorting, bilateral sorting, unilateral typing, and bilateral typing) while wearing accelerometers on both wrists. Two variables, the Bilateral Magnitude and Magnitude Ratio, were derived from accelerometry data to distinguish between high- and low-intensity tasks, and between bilateral and unilateral tasks. Estimated energy expenditure and time spent in simultaneous UE activity for each task were also calculated. Results The Bilateral Magnitude distinguished between high- and low-intensity tasks, and the Magnitude Ratio distinguished between unilateral and bilateral UE tasks. The Bilateral Magnitude was strongly correlated with estimated energy expenditure (ρ = 0.74, p<0.02), and the Magnitude Ratio was strongly correlated with time spent in simultaneous UE activity (ρ = 0.93, p<0.01) across tasks. Conclusions These results demonstrate face validity and construct validity of this methodology to quantify bilateral UE activity during the performance of everyday tasks performed in a laboratory setting, and can now be used to assess bilateral UE activity in real-world environments.

    Introduction There is observed increase in detection rate of upper urinary tract urothelial cancer worldwide. This is a result of improved imaging as well as implementation of novel technologies of direct visualization of upper urinary tract. Standard techniques still remain insufficient to diagnose flat urothelial lesions. Carcinoma in situ is characterized by flat disordered proliferation of urothelial cells with marked cytologic abnormality, which occur within one cell layer as well as full thickness urothelium and therefore requires a better technology to pick up early and subtle mucosal changes. Material and methods The review presents available diagnostic tools in detection of upper urinary tract urothelial cancer and their ability to depict carcinoma in situ. Results Ureterorenoscopy is an investigation of choice as various promising techniques are under pilot investigations to enhance visualization of upper urinary tract carcinoma in situ. So far only photodynamic diagnosis has been reported to be as effective in detection of carcinoma in situ in the upper as within the lower urinary tract. Conclusions Although we are close to see upper urinary tract carcinoma in situ all new promising diagnostic techniques still require further validation in multicenter clinical trials to indicate any change to current recommendations.

    [Purpose] This study compared the functional and kinematic changes associated with two rehabilitation protocols: bilateral and unilateral movement training. [Subjects and Methods] Twenty-five patients with chronic stroke were randomly assigned to two training protocols for four weeks of training. Each training session consisted of three tasks. The tasks were performed with either the impaired and unimpaired arms moving synchronously (bilateral training) or with the impaired arm alone (unilateral training). To compare the changes associated with each rehabilitation protocol, functional and kinematic assessments were performed before and after the interventions. The functional state of each patient was measured by the Box and Block Test, and the kinematic variables were assessed by three-dimensional motion analysis. The Box and Block Test was used to assess the functional abilities of the affected upper limb. Kinematic measurements of upper limb movement were measured with a 3-dimensional motion analysis system. [Results] Results showed that the bilateral movement group had significantly improved motion of the shoulder compared to the unilateral movement group. [Conclusion] Bilateral movement training should be used to improve upper limb function in patients with chronic stroke. PMID:27630418

    The purpose of the present study is to describe a case of severe, psoriasiform blepharitis by means of a case report and literature review. A 44-year-old man developed chronic blepharitis and tearing months after bilateral cataract surgery. Exam showed diffuse quad-eyelid erythema, discharge, edema, madarosis, and scale. He also had insufficient tear drainage due to bilateral upper eyelid cicatricial punctal atresia with bilateral lower eyelid punctal stenosis. Biopsy of the lower eyelids exhibited psoriasiform hyperplasia. Topical 0.1% tacrolimus achieved improvement but caused some subjective eye irritation. Psoriasiform dermatitis manifesting on the eyelids is rare, may be associated with insufficient tear drainage, and may respond favorably to 0.1% tacrolimus.

    The da Vinci Surgical System (Intuitive Surgical Inc.) continues to develop as a platform in urological surgery. Synchronous upper and lower urinary tract tumours requiring extirpative surgery are not uncommon. We report the first case robotic series of combined complex upper and lower urinary tract surgery. Six high-risk anaesthetic patients with a median age of 71 years and apparent synchronous upper and lower urinary tract pathologies underwent concurrent robotic surgery. Five underwent robotic nephroureterectomy and robotic-assisted radical cystectomy (RARC); 1 had combined robotic nephroureterectomy and robotic-assisted radical prostatectomy (RALP). The mean length of stay was 10 days, with an average blood loss of 416.7 mL. The median console time for nephroureterectomy, RALP and RARC was 90, 90 and 210 minutes, respectively. Four patients had intra-corporeal ileal conduit urinary diversion. There were no Clavien grade 3, 4, or 5 complications. In all patients, 30- and 90-day mortality was nil. Margins were clear in the entire cohort. We concluded that combined upper and lower urinary tract robotic surgery is safe and technically feasible with acceptable complications and oncological outcomes. PMID:25485015

    Lithium induces proliferation in the epithelium of renal collecting ducts. A recent small-scale cohort study reported a strong association between use of lithium and increased risk of renal neoplasia. We therefore conducted a large-scale pharmacoepidemiologic study of the association between long-term use of lithium and risk of upper urinary tract cancer, including renal cell cancer and cancers of the renal pelvis or ureter. We identified all histologically verified upper urinary tract cancer cases in Denmark between 2000 and 2012 from the Danish Cancer Registry. A total of 6477 cases were matched by age and sex to 259,080 cancer-free controls. Data on lithium use from 1995 to 2012 were obtained from the Danish Prescription Registry. We estimated the association between long-term use of lithium (≥5 years) and risk of upper urinary tract cancer using conditional logistic regression with adjustment for potential confounders. Long-term use of lithium was observed among 0.22% of cases and 0.17% of controls. This yielded an overall nonsignificant adjusted odds ratio (OR) of 1.3 (95% confidence interval [95% CI], 0.8-2.2) for upper urinary tract cancer associated with long-term use of lithium. Analyses stratified by stage and subtype of upper urinary tract cancer revealed slight but nonsignificant increases in the ORs for localized disease (OR, 1.6; 95% CI, 0.8-3.0) and for renal pelvis/ureter cancers (OR, 1.7; 95% CI, 0.5-5.4). In conclusion, in our nationwide case-control study, use of lithium was not associated with an increased risk of upper urinary tract cancer.

    So far extracorporal shockwave lithotripsy (SWL) is the treatment of choice for upper urinary tract stones. Since the introduction of new minimal-invasive endourological procedures, such as retrograde flexible uretero-renoscopy (fURS) and minimal-invasive percutaneous nephrolithotomy (Mini-Perc), alternative treatment modalities are available, which show enhanced stone-free rates and decreased treatment morbidity even in unfavorable stone localizations of the lower calix and calyceal diverticulum stones. In experienced hands modern endourological approaches are suitable as first-line treatment of upper urinary tract stones. Even in elderly patients and large stone burden the endourological techniques show acceptable results.

    Robot-assisted bilateral upper-limb training grows abundantly for stroke rehabilitation in recent years and an increasing number of devices and robots have been developed. This paper aims to provide a systematic overview and evaluation of existing bilateral upper-limb rehabilitation devices and robots based on their mechanisms and clinical-outcomes. Most of the articles studied here were searched from nine online databases and the China National Knowledge Infrastructure (CNKI) from year 1993 to 2015. Devices and robots were categorized as end-effectors, exoskeletons and industrial robots. Totally ten end-effectors, one exoskeleton and one industrial robot were evaluated in terms of their mechanical characteristics, degrees of freedom (DOF), supported control modes, clinical applicability and outcomes. Preliminary clinical results of these studies showed that all participants could gain certain improvements in terms of range of motion, strength or physical function after training. Only four studies supported that bilateral training was better than unilateral training. However, most of clinical results cannot definitely verify the effectiveness of mechanisms and clinical protocols used in robotic therapies. To explore the actual value of these robots and devices, further research on ingenious mechanisms, dose-matched clinical protocols and universal evaluation criteria should be conducted in the future.

    This randomized study was designed to compare the effectiveness of bilateral interpleural analgesia with lumbar epidural analgesia, on postoperative pain relief in upper abdominal surgery. The studied patients were randomely allocated into either interpleural group "IP" (n = 15) or epidural group "EP" (n = 15). In "IP" group, preanesthetic bilateral interpleural block was done using a mixture of bupivacaine 0.5% (0.8 mg/kg) and 2 mg morphine diluted to 50 ml saline for each side. In "EP" group, the same mixture-diluted in 20 ml saline-was injected in the epidural space (L2-3). The general anesthetic technique was the same in both groups. Hemodynamic, gasometric, verbal pain score (VPS) values and complications were compared in both techniques. Heart rate (HR) and mean arterial pressure (MAP) readings were in the accepted normal range in the perioperative period although significant lower readings were detected in "EP" group. No significant differences were displayed in blood gasometric variables between the two groups. There were considerable level of analgesia in both groups in the postoperative period although "EP" analgesia was superior to "IP". More pain free patients (9 versus 4) and significant lower consumption of nalbuphine were detected in "EP" group. The results of this study indicate that bilateral "IP" analgesia may offer a satisfactory analgesia for upper abdominal surgery when the use of other analgesic techniques may be contraindicated.

    2008-12-01

    Extracorporeal shockwave lithotripsy (ESWL) is the fragmentation of stone by means of acoustic shockwaves created by an extracorporeal source. ESWL brakes the stone by spallation and squeezing. The optimal frequency for fragmentation is 1Hz. The initial power must be low, then progressively increased during the session. The contra-indications for ESWL are pregnancy, major deformities, severe obesity, aortic aneurism, uncontrolled coagulation disorders, untreated urinary infection, cardiac pacemaker. A stone density of 1000UH is a risk factor for fragmentation failure. The success rate for the kidney and the ureter is 60-80% and 80%, respectively. Stone clearance may be facilitated by alpha blockers. Asymptomatic and non-infected residual fragments less than 4mm must be followed-up annually.

    Purpose This study used the a nationwide population-based retrospective cohort study with the claims data from the Taiwan National Health Insurance Research Database to investigate the risk of urothelial carcinoma (UC) for hemodialysis (HD) patients. Methods The study population consisted of 2689 patients with end-stage renal disease (ESRD) newly diagnosed in 2000-2002 and underwent maintenance HD. Then, 21,449 reference patients were collected without HD randomly selected and matched with sex and age. The exclusion criteria were previous long-term analgesics and Chinese medication usage. Incidence density rates of UC in upper urinary tract (UTUC) and bladder (UBUC) were estimated for both cohorts by the end of 2012. Hazard ratios (HRs) of UC were measured in association with HD, covariates, and comorbidity. Results The incidence of UC was significantly higher in the HD cohort than in the reference cohort for both UT (21.8 vs. 0.65 per 10,000 person-years) and UB (17.7 vs. 3.55 per 10,000 person-years). The multivariate Cox proportional hazard regression analysis showed that the HRs of UTUC in HD cohort was 33.3 (95% CI = 15.9-69.5) and 5.14 for UBUC (95% CI = 3.24-8.15). The risk increased further for HD patients with comorbidity of hematuria, urinary tract infection (UTI) or hydronephrosis. Conclusion Patients with ESRD on HD are at a high risk of developing UC, especially UTUC in Taiwan. They will be paid more frequent to check urine analysis, urine cytology, and upper urinary tract survey. PMID:26956094

    Clear cell adenocarcinoma (CCA) in the urinary tract is a rare neoplasm morphologically identical to the Müllerian counterpart. Clear cell adenocarcinoma is extremely rare in the upper urinary tract. We present a case with CCA of the renal pelvis. Microscopically, the tumor exhibited exophytic growth with predominantly tubulocystic structures, as well as solid and papillary patterns. The neoplastic cells were cuboidal with clear to pale eosinophilic cytoplasm and abundant intracellular and extracellular eosinophilic hyaline globules. By immunohistochemically, the tumor was labeled by cytokeratins and hepatocyte nuclear factor-1β. The patient was still alive without evidence of recurrence in the follow-up period of nineteen months after diagnosis. PMID:24375047

    Upper urinary tract calculi are common; however, there is no recommended treatment selection for elderly patients. Ureteroscopic holmium laser lithotripsy (URS lithotripsy) is minimally invasive, and it provides a high stone-free rate (SFR) treatment for upper urinary tract calculi. Here, we retrospectively evaluated the surgical outcomes of URS lithotripsy after dividing the 189 cases into 3 groups by patient age: the '<65 group' (<65 years old, n=108), the '65-74 group' (65-74 years old, n=42), and the ' 75 group' ( 75 years old, n=39). The patients' characteristics, stone status, and perioperative outcomes were assessed. The 65-74 group and the 75 group had a significantly higher prevalence of hypertension compared to the<65 group. Compared to the<65 group, the 65-74 group had a significantly higher prevalence of hyperlipidemia, and the 75 group had significantly higher the American Society of Anesthesiologists (ASA) scores. Despite these preoperative risk factors, SFR and postoperative pyelonephritis in the 65-74 group and the 75 group were similar to those of the<65 group. In conclusion, URS lithotripsy is the preferred treatment for upper urinary tract calculi, even for elderly patients who have multiple preoperative risk factors. PMID:27339204

    In a study of 290 patients with transitional cell carcinoma of the upper urinary tract an excess of blood group A was found. Comparisons between blood group A versus O and rhesus-positive versus rhesus-negative in relation to tumor stages or grades of dysplasia showed no significant differences neither at presentation nor in actuarial survival rates. It is concluded that the blood group systems ABO and rhesus have no prognostic value in urothelial tumors of the upper urinary tract.

    Primary upper extremity deep venous thrombosis (DVT), or effort thrombosis, typically occurs in young, healthy individuals with a history of repetitive upper extremity movement while secondary upper extremity DVT is associated with a number of predisposing factors. The role of factors such as hypercoagulability in the development of effort thrombosis is less well described. This report describes a previously healthy 21-year-old man who presented with simultaneous bilateral upper extremity DVT after hours of pushing and lifting a heavy wheelbarrow. Treatment included thrombolytic therapy followed by delayed venolysis and vein patch angioplasty. Hypercoagulable screening revealed factor V Leiden heterozygous characteristics. PMID:11565040

    Spontaneous extravasation of urine (SUE) is a rare urologic manifestation. Predisposing conditions of SUE include ureteric calculus, retrograde pyelography, pregnancy, abdominal aorta aneurysm, tumors, or enlargement of the prostate gland. Usually, SUE is a self-limiting condition that mandates differentiaton from other catastrophic conditions of pelviureteric ruptures. Most reported cases of SUE based on urograms are unilateral in presentation. Herein, we report a case of bilateral SUE evident on computed tomography urography in a patient with benign prostatic hyperplasia. We also review the literature briefly. PMID:26649120

    A report is given of the use of diuresis renography and pressure flow studies to diagnose urinary tract obstruction in 41 collecting systems of 33 children. If differential pressures between the renal pelvis and the bladder in excess of 22 cm. water at a flow rate of 10 ml. per minute is accepted as evidence of obstruction and below 15 cm. water is accepted as normal the interpretation of the renogram showing O'Reilly's pattern IIIa as evidence of stasis without obstruction was correct in 74 per cent of the cases. Likewise, the interpretation of O'Reilly's renogram pattern IIIb as showing partial obstruction was correct in only 40 per cent of the cases. Thus, the authors urge caution in the use of the diuresis renogram to diagnose or to rule out upper urinary tract obstruction.

    Objective Temporary vesicostomy is a urinary diversion procedure for patients with upper urinary tract (UUT) dilatation, secondary to bladder outlet obstruction or dysfunction. The aim of this study was to evaluate our experience in children undergoing such diversion, analyzing its efficacy to prevent urinary tract infection (UTI), improve or resolve hydronephrosis, stabilize or improve kidney function and restore the health of UUT. Methods In this retrospective study, patients who had vesicostomy by Blocksom technique due to bladder outlet obstruction or dysfunction were evaluated in Mofid Children’s Hospital (in Tehran) from March 2007 to March 2012. The reason for applying this procedure was failure in clinical treatment. Data regarding gender, age, diagnosis, time of any surgical intervention, associated anomalies, primary/secondary complications and mortality were collected using a questionnaire, and evaluated by giving a grade that ranged from 0 (worst) to 10 (best) based on Lickert’s scale. Findings From a total number of 53 patients, (88.7% male and 11.3% female) with a mean age of 225 days, 66% had posterior urethral valve and 16 (30%) neurogenic bladder. UTI was present in all cases, hydronephrosis in 52 (98.1%), and vesico-ureteral reflux only in 45 (84.9%) patients. Valve ablation was performed in 17 cases, and clean intermittent catheterization in14 patients which were unsuccessful. We performed vesicostomy in all patients. Mortality rate was 7.5%. Vesicostomy was closed in 35 patients. Cure rate was 85% in UTI, 82.7% in hydronephrosis, 80% in VUR, and 86.5% in kidney function. Conclusion Vesicostomy is a simple procedure that protects upper urinary tract, decreases hydronephrosis, and improves kidney function. The procedure is well tolerated and reversible, with less complication and should be considered in children in whom conservative and medical treatment has failed. PMID:24910742

    Objective. We here report a patient with upper urinary tract urothelial carcinoma with hypercalcemia likely due to elevated 1,25-dihydroxyvitamin D. Methods. We present a clinical case and a summary of literature search. Results. A 57-year-old man, recently diagnosed with a left renal mass, for which a core biopsy showed renal cell carcinoma, was admitted for hypercalcemia of 11.0 mg/mL He also had five small right lung nodules with a negative bone scan. Both intact parathyroid hormone and parathyroid hormone-related peptide were appropriately low, and 1,25-dihydroxyvitamin D was elevated at 118 pg/dL. The patient's calcium was normalized after hydration, and he underwent radical nephrectomy. On the postoperative day 6, a repeat 1,25-dihydroxyvitamin D was 24 pg/mL with a calcium of 8.1 mg/dL. Pathology showed a 6 cm high-grade urothelial carcinoma with divergent differentiation. We identified a total of 27 previously reported cases with hypercalcemia and upper tract urothelial carcinoma in English. No cases have a documented elevated 1,25-dihydroxyvitamin D level. Conclusion. This clinical course suggests that hypercalcemia in this case is from the patient's tumor, which was likely producing 1,25-dihydroxyvitamin D. Considering the therapeutic implications, hypercalcemia in patients with upper urinary tract urothelial carcinoma should be evaluated with 1,25-dihydroxyvitamin D. PMID:23476827

    Objective: We compared long-term clinical outcomes of upper urinary tract transitional cell carcinoma (TCC) patients treated by retroperitoneoscopic nephroureterectomy (RNU) or open radical nephroureterectomy (ONU). Methods: Upper urinary tract TCC patients were treated with RNU (n = 86) or ONU (n = 72) and followed-up for more than three years. Demographic and clinical data, including preoperative indexes, intraoperative indexes and long-term clinical outcomes, were retrospectively compared to determine long-term efficacy of the two procedures. Results: The RNU and ONU groups were statistically similar in age, gender, previous bladder cancer history, tumour location, pathologic tumour stage, pathologic node metastasis or tumour pathologic grade. The original surgery time required for both RNU and ONU was statistically similar, but RNU was associated with a significantly smaller volume of intraoperative estimated blood loss and shorter length of postoperative hospital stay. Follow-up (average: 42.4 months, range: 3–57) revealed that the RNU 3-year recurrence-free survival rate was 62.8% and the 3-year cancer specific survival rate was 80.7%. In the ONU group, the 3-year recurrence-free survival and the three-year cancer-specific survival rates were 59.2% and 80.3%, respectively. Neither of the survival rates were statistically different between the two groups. T stage, grade, lymph node metastasis and bladder tumour history were risk factors for tumour recurrence; the operation mode and the bladder cuff incision mode had no correlation with the recurrence-free survival. Conclusion: The open surgery strategy and the retroperitoneoscopic nephroureterectomy strategy are equally effective for treating upper urinary tract TCC. However, the RNU procedure is less invasive, and requires a shorter duration of postoperative hospitalized care; thus, RNU is recommended as the preferred strategy. PMID:22630340

    Upper urinary tract (UUT) transitional cell carcinoma (TCC) is relatively rare tumor. Approximately 0.7-4% of patients with primary bladder cancer develops UUT-TCC. The symptoms related to an UUT-TCC often occur with an advanced stage which leads one to emphasize a surveillance strategy to monitor the UUT to allow for an earlier diagnosis. Although the risk of UUT-TCC after bladder cancer is well established, there is a paucity of recommendations suggesting the optimal method and frequency of monitoring the UUT and there is no consensus among them. This article reviews the recommendations on monitoring the UUT in patients with bladder cancer. PMID:21814316

    Leptospirosis is classified as a re-emerging zoonotic disease with global impor- tance. The aim of this study was to determine urinary shedding of leptospires in healthy dogs and to identify the shedded leptospire species. Furthermore, antibody presence against leptospires was evaluated. In a prospective study urine samples of 200 healthy dogs from Upper Bavaria were randomly collected and evaluated by real-time polymerase chain reaction (PCR) specific for the lipL32 gene of pathogenic Leptospira (L) spp. Positive samples were further character- ized via multilocus sequence typing (MLST) to identify the Leptospira species. Microagglutination test (MAT) was performed to determine serum antibody titers. Three of 200 urine samples were found to be PCR-positive resulting in a urinary shedding prevalence of 1.5% (95% confidence interval 0.3-4.5%). All three dogs had been vaccinated before with a bivalent vaccine, covering the serogroups Canicola and lcterohaemorrhagiae. One dog shed leptospires of the species L. borgpetersenii, and two of the species L. interrogans. Of all dogs, 17.0% had antibody titers ≥ 1:100, and 3.5% titers ≥ 1:400 to serovars of non-vaccinal sero- groups. Healthy dogs that shed leptospires represent a possible risk for humans and other animals. The study emphasizes the importance of general hygiene measures in veterinary practice while handling urine of all dogs, and the use of vaccines that protect against a broader range of serogroups and that prevent urinary shedding.

    Glomerular filtration rate (GFR), an important parameter of renal function, is difficult to assess clinically. Serum creatinine and blood urea nitrogen measurements lack sensitivity, whereas radionuclide determination of GFR is not always available and requires postinjection patient isolation. GFR can be determined using computed tomography (CT), most commonly via Patlak plot analysis. Four adult cats, two adult dogs, and a foal underwent abdominal CT under general anesthesia for various diseases of the upper urinary tract. CT-GFR was measured with a single-slice dynamic acquisition and Patlak plot analysis. In five animals, the total CT-GFR appeared to be below normal, corresponding with mild (two animals) and moderate (two animals) increases of serum creatinine in four. In the two animals with normal or increased CT-GFR, serum creatinine was within the reference values. A significant negative logarithmic relationship was found between CT-GFR and serum creatinine values (P = 0.008; r2 = 0.75). No complications occurred during or following CT-GFR. CT examination provided clinically relevant information in 3/5 patients with possible ureteral obstruction and in 3/3 patients with suspected ureteral calculi. Single-slice dynamic CT-GFR was practical and provided clinically useful information in this small series of patients undergoing CT of the upper urinary tract. There was a significant relationship between CT-GFR and serum creatinine values, which supports the clinical potential of CT-GFR and justifies further investigation of this technique. PMID:20806874

    The most common pathology of the kidney and upper urinary tract includes nephrolithiasis, ureteral strictures and renal cysts. In the treatment of patients with these diseases, the majority of surgeons prefer minimally invasive techniques, including endoscopic surgery. The complication rate of percutaneous surgery is a major factor in encouraging the search for new treatments. We have analyzed the results of 402 x-ray-endoscopic operations performed with the use of technologies based on titanium nickelide materials in patients with nephrolithiasis, ureteral strictures and kidney cysts. The high effectiveness and reliability of porous titanium nickelide cryoapplicator was noted in control of percutaneous channel bleeding and prevention. The proposed suspension nephropexy with fine titanium granules in coexisting nephrolithiasis and nephroptosis demonstrated 1.5 times greater effectiveness compared to the traditional nephropexy, reducing duration of nephrostomy and rehabilitation by almost 3 times. The proposed methods of intubation by permanent and temporary stents with shape memory after percutaneous ureteropelvic junction stricture correction are promising in the treatment of patients with this pathology of the upper urinary tract. Application of titanium nickelide implants in simple renal cyst surgery has led to a significant increase in the effectiveness of these operations, improvement in long-term results and patients' quality of life.

    Cystadenolymphomas (Warthin's tumors) are the second most frequent lesions of the parotid gland. Due to their benign clinical behavior, the low rates of recurrence and malignant transformation they were classified as tumor-like lesions. In addition, a polyclonal growth of the epithelial components of the tumor could be detected. Warthin's tumors occur bilateral in 7-10%, whereas a multifocal appearance is extremely rare. Even if the pathogenesis is still unclear a heterotopia of salivary tissue during embryogenesis is the most likely explanation for the origin of these tumors in the upper neck and periparotideal region. Here we present a rare case of bilateral, multifocal, extraglandular Warthin's tumors in lymph nodes of the upper neck and give a brief review of the literature. If a primary malignancy can be excluded by a careful staging procedure prior to the operation an isolated excision of the lesions of the neck is the adequate treatment.

    A 60-year-old female with an extensive history of stone disease and shock wave lithotripsy presents with recurrent and increasingly severe renal colic. Work-up reveals obstruction with translucent debris that is found to be composed of keratin. Her history of chronic irritation of the collecting system has resulted in keratinizing squamous metaplasia (KSM) with hyperkeratosis that has sloughed from the upper urinary tract and has become lodged in the ureter. Because of the worsening of her symptoms on conservative management, the patient elected for a nephrectomy and her symptoms have since resolved. KSM of the renal pelvis is a relatively rare phenomenon and most often presents with irritative symptoms. It is thought to result from chronic irritation of the urothelium. KSM has been found to be coincident with squamous cell cancers of the urinary tract, though clear data implicating KSM as a premalignant lesion is lacking. We present a case of recurrent renal colic secondary to sloughing keratin debris from KSM. PMID:26249552

    Abstract Background: Obstructive nephropathy is an uncommon side effect of sulfadiazine, which is used for the treatment of toxoplasmosis. We present a case of acute renal colic and urine extravasation of a patient shortly after she was started on this medication. Case Presentation: A 31-year-old female presented with acute renal colic 2 weeks after starting treatment with sulfadiazine and pyrimethamine for ocular toxoplasmosis. Results: A noncontrast computed tomography revealed left hydronephrosis and fluid located around the kidney and in the left gutter. There were no urinary stones. Administration of intravenous contrast revealed significant urine extravasation at the level of the ureteropelvic junction. Intravenous contrast injection confirmed that the extravasation consisted of urine leakage at the ureteropelvic junction. Her clinical condition improved with the insertion of an internal stent, which was left in place for 4 weeks. A retrograde pyelography performed at the time of the internal stent removal ruled out persistent extravasation and filling defects in the left upper urinary tract. Considering the clinical circumstances and the imaging results, it appears that this is a first reported case of sulfadiazine-induced obstructive uropathy associated with urine extravasation. Conclusion: Although rare, obstructive uropathy related to sulfadiazine medication should be promptly suspected, diagnosed, and treated. Patients should be instructed to substantially increase their liquid intake while on that medication. PMID:27704057

    We report a case in which retroperitoneoscopic pyelolithotomy was the procedure selected to treat a large stone in the upper urinary tract. A 71-year-old woman who had multiple cerebral infarction and dementia was admitted with a persistent high fever unresponsive to antibiotics. The diagnosis was pyelonephritis and urosepsis associated with ureteral calculus. A large calculus(3.0 x 2.0 cm)was found in the left ureter at the L3 level. She underwent nephrostomy of the left side. After the patient's general condition had improved, surgery was performed successfully with an uneventful recovery. The findings in this case confirm that retroperitoneoscopic surgery allows removal of a large stone in a single, minimally invasive procedures. PMID:16049564

    The objective of this study is to present the outcomes of flexible ureteroscopic laser lithotripsy (URS) for upper urinary tract stone disease in spinal cord injury (SCI) patients performed by a single surgeon. A retrospective analysis was performed for SCI patients treated with flexible URS for proximal ureter and kidney stone disease by a single surgeon between 2003 and 2013. Patient characteristics, operative outcomes, metabolic evaluation, and stone analyses were assessed in detail. A total of 27 URS procedures were performed for urolithiasis in 21 renal units of 19 patients. The mean age was 52.1 ± 15.6 years (16-72) and mean BMI was 29.2 ± 7.3 kg/m(2) (20-45.7). Etiology of SCI was trauma (n: 10), multiple sclerosis (n: 6), cerebrovascular accident (n: 1), or undetermined (n: 2). The mean stone size was 15.9 ± 8.6 (6-40) mm. In the 27 URS procedures, stones were located in the ureter (n: 5), the kidney (n: 14), and both areas (n: 8). Mean hospitalization time was 2.0 ± 2.4 (0-10) days. Postoperative complications were observed in 6 cases (22.2%). Three major complications included urosepsis (n: 1) and respiratory failure (n: 2), that were observed postoperatively and required admission to the intensive care unit. The 2 minor complications were hypotension, fever and UTI, and required medical treatment. Fourteen (66.6%) of the 21 renal units were stone free. Calcium phosphate carbonate (n: 9) and struvite (n: 5) were the primary stone compositions detected. Hypocitraturia (n: 6), hypercalciuria (n: 5), hypernaturia (n: 5), hyperoxaluria (n: 4), and hyperuricosuria (n: 1) were common abnormalities in 24-h urine analysis. Ureteroscopic laser lithotripsy can be an effective treatment modality for SCI patients with upper urinary tract calculi.

    Congenital abnormalities of the kidney and urinary tract (CAKUT) include a wide range of abnormalities ranging from asymptomatic ectopic kidneys to life threatening renal agenesis (bilateral). Many of them are detected in the antenatal or immediate postnatal with a significant proportion identified in the adult population with varying degree of severity. CAKUT can be classified on embryological basis in to abnormalities in the renal parenchymal development, aberrant embryonic migration and abnormalities of the collecting system. Renal parenchymal abnormalities include multi cystic dysplastic kidneys, renal hypoplasia, number (agenesis or supernumerary), shape and cystic renal diseases. Aberrant embryonic migration encompasses abnormal location and fusion anomalies. Collecting system abnormalities include duplex kidneys and Pelvi ureteric junction obstruction. Ultrasonography (US) is typically the first imaging performed as it is easily available, non-invasive and radiation free used both antenatally and postnatally. Computed tomography (CT) and magnetic resonance imaging (MRI) are useful to confirm the ultrasound detected abnormality, detection of complex malformations, demonstration of collecting system and vascular anatomy and more importantly for early detection of complications like renal calculi, infection and malignancies. As CAKUT are one of the leading causes of end stage renal disease, it is important for the radiologists to be familiar with the varying imaging appearances of CAKUT on US, CT and MRI, thereby helping in prompt diagnosis and optimal management.

    Introduction: Congenital hypothyroidism (CH) may be significantly associated with congenital malformations. However, there is little evidence on the relationship between renal and urinary tract anomalies and CH. Objectives: The aim of this study was to compare the renal and upper urinary tract anomalies in children with and without primary CH (PCH). Patients and Methods: This case-control study was conducted on 200 children aged 3 months to 1 year, referring to Amir-Kabir hospital, Arak, Iran. One hundred children with PCH, as the case group, and 100 children without CH, as the control group, were selected. For all children, ultrasonography and other diagnostic measures (if necessary) were performed to evaluate renal and upper urinary tract anomalies (ureter and bladder). Results: The frequency of renal and upper urinary tract anomalies among 43 children with primary CH, with 83 cases (72.8%), was significantly higher than the frequency of anomalies among the 19 children in the control group, with 31 cases (27.1%) (OR = 3; CI 95%: 1.6-5.4; P = 0.001). Among the anomalies studied, only the differences in frequency of uretero-pelvic junction obstruction (UPJO) (OR = 6; CI 95%: 1.3-28; P = 0.018) and hydronephrosis (OR = 22; CI 95%: 5-95; P = 0.001) was significant between the two groups. Conclusion: Our study demonstrated that PCH is significantly associated with the frequency of congenital anomalies of the kidneys and upper urinary tracts. However, further studies are recommended to determine the necessity of conducting screening programs for anomalies of the kidneys and urinary tract in children with CH at birth. PMID:26693499

    Lymphadenectomy for urothelial carcinoma of the upper urinary tract has attracted the attention of physicians. The mapping study of lymphatic spread has shown that a relatively wide area should comprise the regional nodes for tumors of the right renal pelvis or the right upper two-thirds of the ureter. A prospective study showed that an anatomical template-based lymphadenectomy significantly improved patient survival in tumors of the renal pelvis. This benefit was more evident for patients with pT2 stage tumors or higher. The risk of regional node recurrence is significant reduced by template-based lymphadenectomy, which is likely to be associated with improved patient survival. The removal of lymph node micrometastases is assumed to be the reason for therapeutic benefit following lymphadenectomy. The number of resected lymph nodes can be used to assess the quality of lymphadenectomy, but not to determine the extent of lymphadenectomy. The guidelines currently recommend lymphadenectomy for patients with muscle-invasive disease, even though the current recommendation grades are still low. The present limitation of lymphadenectomy is the lack of standardization of the extent of lymphadenectomy and the randomized trials. Further studies are warranted to collect the evidence to support lymphadenectomy. PMID:26677437

    The article introduces a clinical example of a patient who was first diagnosed with bladder cancer, which contributed to the development of end-stage renal failure. Initially, given the significant upper urinary tract retention and post renal acute renal failure, the patient underwent bilateral percutaneous nephrostomy. Taking into account periodic gross hematuria, cystoscopy and transurethral electrocoagulation and biopsy of bladder tumor were performed and bladder cancer was identified. Despite adequate functioning of nephrostome drainage and daily urine output up to 3000 ml, kidney failure was not resolved. After creation of an arteriovenous fistula, a hemodialysis program was launched. The patient continued to experience persistent gross hematuria, he had a hectic fever, which was estimated as a symptom of acute pyelonephritis. The patient was scheduled for bilateral nephroureterectomy, cystoprostatectomy as the only option to remove the source of bleeding and infection. The operation was carried out without complications. The patient is currently maintained on chronic hemodialysis and followed by an oncologist at the place of residence; there are no data of bladder

    Purpose To report our initial clinical experience and perioperative outcomes of retroperitoneal laparoendoscopic single-site surgery (RLESS) for upper urinary tract surgery. Materials and Methods Between June 2009 and October 2010, we performed RLESS in 23 patients for various indications including radical nephrectomy (n=4), nephroureterectomy (n=2), simple nephrectomy (n=10), and renal cyst ablation (n=7). RLESS was performed with a homemade single-port device with a conventional rigid laparoscopic instrument and laparoscope. The parameters analyzed were age, body mass index, operative time, estimated blood loss, transfusion, time of oral intake, visual analogue pain scale score (VAPS), length of hospital stay, and complications. Results One case of simple nephrectomy was converted to open nephrectomy because of severe adhesion and inadequate surgical exposure. RLESS was completed in 23 patients. Mean operative time was 168.7±29.2, 227.5±50.0, 230.0±56.5, and 70.5±8.9 minutes for simple nephrectomy, radical nephrectomy, nephroureterectomy, and renal cyst ablation, respectively. Estimated blood loss was 113.0±149.8, 170.0±156.8, 400.0±141.4, and 22.8±16.0 ml. The time to oral intake after surgery was 1.4±0.5, 1.2±0.5, 1.5±0.7, and 1.1±0.3 days. The mean VAPS score was 1.1±0.2, 2.1±0.5, 2.0±0.5, and 1.0±0.0 of 10 (range, 0.8 to 2.6). The hospital stay was 4.6±1.5, 3.7±0.5, 6.0±1.4, and 3.2±1.7 days. No major perioperative complications were observed. Conclusions The initial outcomes of our experience suggest that RLESS is a technically feasible and safe procedure for upper urinary tract surgery. Prospective comparative studies with conventional retroperitoneal laparoscopic surgery are needed to confirm the potential benefits of RLESS. PMID:22216397

    Management strategy for upper urinary tract calculi in small children is still a matter controversial. We report successful management of ureteral stone with transurethral ureterolithotripsy (TUL) in 2 boys weighing around 10 kg. Case 1: A 2-year-old boy (78 cm in height, 9.6 kg in weight), who received hydrocortisone and fludrocortisone for the treatment of 21-hydroxylase deficiency, was referred to our hospital with a right 9-mm lower ureteral stone. For TUL, a 7.5 Fr rigid cystoscope was introduced into the ureter directly after dilation of the ureteral orifice. By using Holmium:YAG laser for lithotripsy, complete stone evacuation was achieved. Stone analysis showed the composition of calcium phosphate and calcium oxalate. Case 2: A 1-year-old boy (80 cm in height, 10.5 kg in weight) with neurofibromatosis type 1 was referred to our hospital with a left 7.5-mm ureteral stone at the ureteropelvic junction. TUL was performed using a 4.5 F rigid ureteroscope and Holmium:YAG laser. No residual stone was identified. Stone analysis showed the composition of calcium oxalate. TUL is a safe and feasible option for small children, even in boys weighing approximately 10 kg. PMID:26717789

    Currently, the treatment of choice in urothelial tumors of the upper urinary tract is nephroureterectomy (NU) as an Open procedure (ONU), though the laparoscopic treatment is now routinely performed as a minimally invasive therapy (LNU). LNU has demonstrated oncologic safety at least equivalent to open, but some issues dealing with cancer still remain. We retrospectively analyzed data from 36 LNU performed between 2006 and 2010, compared with data of 32 ONU performed in 2002-2005 (pre-laparoscopy era). The mean follow-up was 23 months in patients undergoing LNU and 42 months for those treated with ONU. In particular, we evaluated cancer recurrence, the site of recurrence and survival rates. We had local recurrence in 3 patients (8.3%) after LNU and 2 after ONU (6.25%). 2 patients who underwent LNU (5.5%) died of metastatic disease at 9 and 12 months; 3 patients who underwent ONU (9.3%) died of metastasis at 12, 16 and 23 months, respectively. Bladder recurrence was observed in 3 patients after ONU and in 4 after LNU. The most frequent sites of cancer recurrence were: local recurrence (3 LUN, 2 ONU), 1 laparoscopic port recurrence, 3 regional lymph node recurrences (2 LNU, 1ONU), bladder recurrences (3 LNU, 4 ONU). There were no significant differences in disease recurrence and even survival rates at 1 and 3 years were not very different between the two techniques. The grade and stage of cancer affecting the incidence of metastatic disease, as well as the localization of early disease (pelvis-ureter-both) is a negative prognostic factor, rather than the surgical technique used. Therefore, there is no evidence that the control is compromised in cancer patients treated with LNU rather than with ONU.

    Intradetrusor injections of botulinum toxin are the cornerstone of medical treatment of neurogenic detrusor overactivity. The primary aim of this treatment is to ensure a low pressure regimen in the urinary bladder, but the mechanisms leading to long-term protection of the urinary tract remain poorly understood. In this paper, we highlight the potential benefits of intradetrusor injections of botulinum toxin regarding local effects on the bladder structures, urinary tract infections, stone disease, vesico ureteral reflux, hydronephrosis, renal function based on a comprehensive literature review.

    Surgical management of upper urinary tract transitional cell carcinoma (UUT-TCC) has significantly changed over the past two decades. Data for several new surgical techniques, including nephron-sparing surgery (NSS), is emerging. The study systematically reviewed the literature comparing (randomised and observational studies) surgical and oncological outcomes for various surgical techniques MEDLINE, EMBASE, Cochrane Library, CINAHL, British Nursing Index, AMED, LILACS, Web of Science, Scopus, Biosis, TRIP, Biomed Central, Dissertation Abstracts, ISI proceedings, and PubMed were searched to identify suitable studies. Data were extracted from each identified paper independently by two reviewers (B.R. and B.S.) and cross checked by a senior member of the team. The data analysis was performed using the Cochrane software Review manager version 5. Comparable data from each study was combined in a meta-analysis where possible. For dichotomous data, odds ratios with 95% confidence intervals (CIs) were estimated based on the fixed-effects model and according to an intention-to-treat analysis. If the data available were deemed not suitable for a meta-analysis it was described in a narrative fashion. One randomised control trial (RCT) and 19 observational studies comparing open nephroureterectomy (ONU) and laparoscopic NU (LNU) were identified. The RCT reported the LNU group to have statistically significantly less blood loss (104 vs 430 mL, P < 0.001) and mean time to discharge (2.30 vs 3.65 days, P < 0.001) than the ONU group. At a median follow-up of 44 months, the overall 5-year cancer-specific survival (CSS; 89.9 vs 79.8%) and 5-year metastasis-free survival rates (77.4 vs 72.5%) for the ONU were better than for LNU, respectively, although not statistically significant. A meta-analysis of the observational studies favoured LNU group for lower urinary recurrence (P < 0.001) and distant metastasis. The meta-analyses for local recurrence for the two groups were comparable

    Double-J stent insertion has been generally performed during laparoscopic upper urinary tract (UUT) surgical procedures to prevent transient urinary tract obstruction and postoperative flank pain from ureteral edema and blood clots. Several restrictive conditions that make this procedure difficult and time consuming, however, include the coiled distal ends of the flexible Double-J stent and the limited bending angle of the laparoscopic instruments. To overcome these limitations, we devised a Double-J stent insertion method using the new J-tube technique. Between July 2011 and May 2013, Double-J stents were inserted using the J-tube technique in 33 patients who underwent a laparoscopic UUT surgical procedure by a single surgeon. The mean stent placement time was 4.8±2.7 minutes, and there were no intraoperative complications. In conclusion, the J-tube technique is a safe and time-saving method for Double-J stent insertion during laparoscopic surgical procedures.

    A 30-year-old man attended the emergency department with a 4-day history of progressive, bilateral upper limb weakness. He had mild shortness of breath and occasional swallowing difficulties. One month prior to presentation, he had flu-like symptoms and diarrhoea. Examination revealed upper limb hypotonia, symmetrical distal arm weakness and hyporeflexia. Power and reflexes in the lower limbs were normal. Nerve conduction studies and lumbar puncture demonstrated features consistent with Guillain-Barré syndrome (GBS). The patient was treated with a 5-day course of intravenous immunoglobulins. He improved significantly over the next 2 weeks. Breathing and swallow function did not deteriorate and required no further intervention. He had a sustained improvement, and remained at baseline 1 year later. Work-up for underlying structural, infectious, inflammatory and paraneoplastic aetiologies were negative. Serum antiganglioside antibodies were positive for the anti-GT1a IgG isotype supporting the clinical diagnosis of the pharyngeal-cervical-brachial variant of GBS.

    Standard treatment for upper urinary tract urothelial carcinoma (UUTUC) implies the radical removal of all urothelium-lined tissue, which requires nephroureterectomy with bladder cuff removal. We report on a patient with a rare coincidence of UUTUC and horseshoe kidney in whom a preoperative angiography helped to identify and subsequently embolize an abberant isthmic feeding artery, which was located in between both collecting systems. Ischemic discoloration of the isthmus area facilitated resection and no major blood loss occurred. Preoperative superselective embolization of the isthmus as the renal split area can be an effective tool to facilitate nephroureterectomy in the case of a horseshoe kidney.

    Nephronia or focal acute nephritis corresponds to a localized inflammatory non-liquefactive kidney infection which may involve parenchyma of one or more renal lobes. It has been suggested that nephronia is part of the spectrum of upper urinary tract infections between acute pyelonephritis and renal abscess. It is associated with a prolonged clinical course, higher levels of inflammatory markers and an increased risk of renal scarring, compared to pyelonephritis. Ultrasound plays a useful role. Nephronia is an under-diagnosed condition, thus, clinical suspicion is important for early diagnosis and appropriate treatment. We present three paediatric cases, and a review of the literature.

    Experimental data demonstrate that sinusoidal modulated currents are capable of increasing the frequency and amplitude of smooth muscle biopotentials in animal ureter. Basing on these findings, the authors conducted stone fragments elimination from the upper urinary tracts of patients subjected to pulse lithotripsy by means of an original physiotherapeutic complex: oral mineral water, sodium chloride baths, dynamic amplipulse therapy with 3-4 electrodes pairs applied on the renal area and different ureteral regions. The stones passage from the upper urinary tracts was reported in 91.7% of the cases. Functional improvement in the affected kidney is attributed to the stone elimination and antiinflammatory action of the above balneotherapeutic complex.

    Background The introduction of sophisticated treatment of bladder dysfunction and hydrocephalus allows the majority of SB patients to survive into adulthood. However, no systematic review on urological outcome in adult SB patients is available and no follow-up schemes exist. Objectives To systematically summarize the evidence on outcome of urinary tract functioning in adult SB patients. Methods A literature search in PubMed and Embase databases was done. Only papers published in the last 25 years describing patients with open SB with a mean age >18 years were included. We focused on finding differences in the treatment strategies, e.g., clean intermittent catheterization and antimuscarinic drugs versus early urinary diversion, with regard to long-term renal and bladder outcomes. Results A total of 13 articles and 5 meeting abstracts on urinary tract status of adult SB patients were found describing a total of 1564 patients with a mean age of 26.1 years (range 3–74 years, with a few patients <18 years). All were retrospective cohort studies with relatively small and heterogeneous samples with inconsistent reporting of outcome; this precluded the pooling of data and meta-analysis. Total continence was achieved in 449/1192 (37.7%; range 8–85%) patients. Neurological level of the lesion and hydrocephalus were associated with incontinence. Renal function was studied in 1128 adult patients. In 290/1128 (25.7%; range 3–81.8%) patients some degree of renal damage was found and end-stage renal disease was seen in 12/958 (1.3%) patients. Detrusor-sphincter dyssynergy and detrusor-overactivity acted as adverse prognostic factors for the development of renal damage. Conclusions These findings should outline follow-up schedules for SB patients, which do not yet exist. Since renal and bladder deterioration continues beyond adolescence, follow-up of these individuals is needed. We recommend standardization in reporting the outcome of urinary tract function in adult SB

    ABSTRACT Objective: To report our experience of minimally invasive percutaneous nephrolithotomy(MPCNL) in managing upper urinary tract calculi complicated with severe spinal deformity. Materials and Methods: Between August 2001 to December 2012, 16 upper urinary calculi in 13 patients with severe spinal deformity were treated by MPCNL. Preoperative investigation of the respiratory function, evaluation of anatomy by intravenous urography (IVU) and CT scan, and preoperative kidney ultrasonagraphy with simulation of the percutaneous puncture were performed in all patients. The percutaneous puncture was guided by ultrasonography. Results: A total of 19 MPCNL procedures were performed in 16 kidneys, with an average 1.2 procedures in each kidney. Three kidneys needed two sessions of MPCNL, and 2 kidneys needed combined treatment with retrograde flexible ureterscopic lithotripsy. All procedures were successfully completed with no major complications during or after surgery. The mean (range) operative duration was 67 (20-150) min and the mean postoperative haemoglobin drop was 1.0 (0.2-3.1) g/dL. Complete stone-free status was achieved in 14 kidneys. At a mean follow-up of 48(3-86) months, recurrence of small lower calyx stone was detected in one patient. Recurrent UTI was documented by urine culture in two patients and managed with sensitive antibiotics. Conclusion: PCNL for patients with severe spinal deformities is challenging. Ultrasonography-assisted puncture can allow safe and successfully establishment of PCN tract through a narrow safety margin of puncture and avoid the injury to the adjacent organs. However, the operation should be performed in tertiary centers with significant expertise in managing complex urolithiasis. PMID:27509373

    To validate the policy of administering cefazolin (CEZ) as a first-line antibiotic to children who are hospitalized with their first febrile urinary tract infection (UTI), we evaluated microbial susceptibility to CEZ and the efficacy of CEZ. The 75 enrolled children with febrile UTI were initially treated with CEZ. Switching CEZ was not required in 84% of the patients. The median fever duration, prevalence of bacteremia, prevalence of UTI caused by extended-spectrum β-lactamase (ESBL)-producing Escherichia coli, and median duration of hospitalization were significantly higher in the CEZ-ineffective group. The risks of vesicoureteral reflux, indication of operation, and renal scarring are not increased, even when CEZ is ineffective as a first-line antibiotic. CEZ is effective in more than 80% of pediatric patients with their first febrile UTI, but it should be switched to appropriate antibiotics considering sepsis or the ESBL-producing Enterobacteriaceae pathogen, when fever does not improve within 72 hours.

    A total of 66 patients with low grade, low stage transitional cell carcinoma of the bladder who were treated with intravesical bacillus Calmette-Guerin (BCG) underwent cystourethrography to detect vesicoureteral reflux. BCG was instilled weekly for 6 weeks and monthly thereafter for up to 24 months. Whenever vesicoureteral reflux was found or morphological abnormalities were detected on excretory urography (IVP) an isotope renal scan was performed to evaluate the relative renal function. Vesicoureteral reflux was found in 13 patients (19.7%): 10 had grades 1 and 2A, and 3 had grade 2B reflux. The number of BCG instillations ranged from 8 to 22. IVPs were normal in 11 patients. In 2 patients mild unilateral dilatation was present before BCG instillations, and this remained unchanged during and after therapy. None of the 13 patients with vesicoureteral reflux had IVP features suggestive of urinary tuberculosis. In 11 patients the refluxing renal systems had normal relative renal function (50 to 55%). Two patients had a decrease to 40% of the relative renal function with normal IVPs, suggesting a nonBCG related cause. We conclude that BCG therapy is safe in patients with minimal reflux.

    Introduction The aim of this study is to review 10 years experience of retroperitoneoscopy procedures. Methods 600 patients treated between 1995 and 2007 netroperitoneoscopy (nephrectomy, partial and total nephrectomy, adrenalectomy, pyeloplasty, renal cyst, calyceal diverticulectomy) were reviewed for per, peri and post operative complications including patients in the learning curve. Results The mean blood loss was 159mL. Conversion to open surgery was required in 28 patients (4.6%) primarily due to technical problems during dissection (elective). There were 32 (5.3%) surgical complications, including bleeding or hematomas in 12 cases and 2 of them required reintervention, urinomas in 8 which were treated by installation of a ureteral drainage (JJ stent). Wound or deep abscesses happened in 4, urinary fistula in 1 and pancreatic fistula in another. Evisceration (hernias) was seen in 3 patients. Intestinal injury occurred in 2. The complication rate depended on the difficulty of the procedure and learning curve of the surgeon. Twenty eight patients (4.6%) presented medical post-operative complications (hyperthermias, deep venous thrombosis, pyelonephritis, pulmonary superinfections, pulmonary atelectasia and transient vascular ischemic accident). Mean postoperative hospital stay was 6.2 days (ranged from 2 to 20). Conclusion Retroperitoneoscopy can be the technique of choice for accessing and carrying out all the surgery of the upper urinary tract respecting the principles of oncological surgery. After experience with 600 cases during the last 10 years the technique has become safe, simplified, reproducible and effective although not easy. Most complications are minor and easily managed.

    Purpose: Urothelial carcinoma (UC) is a type of tumor, especially of the urinary bladder, that affects people worldwide. Clarification of its detailed tumor biology and discovery of potential targets for developing treatment strategies are imperative because of frequent recurrences and poor prognosis of advanced UCs. By data mining a published dataset of UC of bladder (UCB) transcriptome (GSE31684) from Gene Expression Omnibus, National Center of Biotechnology Information (GEO, NCBI), we identified that THBS2 was the most significantly upregulated gene among those related to structural molecule activity (GO:0005198). Therefore, we evaluated the clinical significance and prognostic impact of thrombospondin-2 (THBS2) protein, A.K.A. TSP2, which encoded by THBS2 gene. Materials and Methods: THBS2 immunostaining was performed in 340 UCs of upper urinary tract (UC-UUTs) and 295 UCBs; subsequently, both groups were dichotomized into high- and low-expression subgroups. Moreover, statistical analyses were performed to correlate the association between THBS2 expression and clinicopathological parameters with two survival indexes: disease-specific survival (DSS) and metastasis-free survival (MeFS). Results: High THBS2 immunoexpression was significantly associated with advanced primary tumor status, nodal metastasis, and vascular invasion in both UC-UUT and UCB groups (all P ≤ .001). In addition, THBS2 overexpression was linked to adverse DSS and MeFS in univariate analyses and served as an independent prognosticator indicating poor outcomes in both groups in multivariate analyses. Conclusion: THBS2 may play a crucial role in UC progression and may be a novel prognostic marker. Additional investigations to elucidate the molecular pathway are necessary for developing potential THBS2-targeted therapies for UCs. PMID:27471570

    The incidence of pediatric urolithiasis is increasing. While many smaller stones may pass spontaneously, surgical therapy is sometimes warranted. Surgical options include shock wave lithotripsy, ureteroscopy, percutaneous nephrolithotomy, and open surgery. Ureteroscopy represents a minimally invasive approach, and it is increasingly being used to treat pediatric upper tract calculi. Ureteroscopy is performed under anesthesia and fluoroscopic guidance, with basket extraction or lithotripsy of the calculi. Technical considerations include active or passive ureteral dilatation, the use of ureteral access sheaths for larger stone burdens, and post-operative stent placement. The current pediatric literature suggests high success rates (equal to or surpassing shock wave lithotripsy) and low complication rates. However, concerns remain regarding feasibility in patients with variant anatomies and risk due to intra-operative radiation exposure.

    We report on the to date largest recovery of 11 organs from a single deceased donor with the transplantation of face, bilateral upper extremities, heart, 1 lung, liver (split for 2 recipients), kidneys, pancreas, and intestine. Although logistically challenging, this case demonstrates the feasibility and safety of the recovery of multiple thoracic and abdominal organs with multiple vascular composite allotransplants and tissues. Our experience of 8 additional successful multiple vascular composite allotransplants, thoracic, and abdominal organ recoveries suggests that such procedures are readily accomplishable from the same deceased donor.

    We studied the influence of pressure and rate of irrigative liquid flow on hydrodynamics of the upper urinary tracts in contact pneumatic lithotripsy (Litoclast lithotriptor) in 68 patients with ureteroliths and nephrostomic drainage. To a nephrostome the device was attached on which the linear change of pressure inside the pelvis was measured at the moment of visualization of the stone, its destruction and final ureteroscopy. 45 patients had nephrostome with a pelvis curl. In this group of patients at the moment of stone destruction the pressure inside the pelvis and the speed of irrigative flow were increased. In patients with marked local inflammation on the place of stone location the pressure inside the pelvis was the highest. The effect of communicating vessels was seen. The stone was completely destroyed in 34 (75.5%) patients, in 9 (20%) patients the stone was destroyed partially. In 2 cases the stone migrated in the cavitary system of the kidney. A nephrostome-intubator was placed antegradely in 23 patients. The balloon-obturator was placed in the ureter above the stone through the nephrostome. The pressure inside the pelvis during contact lithotripsy was not increased. Full destruction of the stone was achieved in 26 patients (92.8%), migration of the stone in the cavitary system and partial destruction of the stone was observed in 2 (2.2%) patients.

    Interactions between infiltrating macrophages in the tumor microenvironment (TME) and tumor cells contribute to tumor progression. The potential impacts of recruited macrophages to the upper urinary tract urothelial cell carcinomas (UUTUCs) progression remain unclear. Here we found human UUTUCs might recruit more macrophages than surrounding normal urothelial cells in human clinical specimens and in in vitro co-culture experiments with UUTUC cells and macrophages. The consequences of recruiting more macrophages to UUTUCs might then enhance UUTUC cell growth, migration and invasion. Further investigation found that the androgen receptor (AR) not only enhanced UUTUC cells capacity to recruit more macrophages, it could also promote the macrophages-enhanced UUTUC cells growth, migration and invasion. Downstream AR target cytokine search found AR might function through modulating CCL5 expression to influence UTTUC progression. Interruption of CCL5 partially reversed the AR-regulated macrophage-enhanced UUTUC progression. AR in UUTUC cells also increased tumor formation in vivo. Taken together, these results suggest that macrophages recruitment may enhance UUTUC progression, modulated by AR-CCL5 signal through alterations in chromatin state to establish a tumor microenvironment with recruited macrophages and cytokines to facilitate cell growth, migration and invasion.

    ABSTRACT Purpose: The place of oncological cases of upper urinary system in the laparoscopic learning curve was investigated. Materials and Methods: A total of 139 patients from two different centers underwent laparoscopic operations and were included in this retrospective study. Results: Mean operative times for oncological, and non-oncological cases were 101.3 (range 60-450), and 102.7 (45-490) minutes respectively. Fourty-two (31.3 %) patients were oncological cases. In 4 oncological cases, the surgeons switched to open surgery because of massive bleeding and six (14.2 %) oncological cases required blood transfusions during peri/postoperative periods. Pulmonary embolism was observed in one oncological case. In one non-oncological case, the surgeon switched to open surgery because of intestinal perforation and 10 (9.7 %) non-oncological cases needed blood transfusions during peri/postoperative periods. In addition, some complications such as intestinal perforation (n=1), mechanical ileus (n=1), and pulmonary embolism (n=1) were observed during postoperative period. Intestinal perforation was repaired using laparoscopic (n=1) method. Mechanical ileus was approached with open surgical technique. Mean hospital stay of the patients in the oncological and non-oncological series were 4.5 (3-23) and 4.5 (3-30) days respectively. Conclusion: We think that renal oncological cases should be included in the spectrum of laparoscopic indications even at the beginning of the learning curve. Certainly, we still share the opinion that cancer cases which require highly challenging surgeries like radical cystectomy, and prostatectomy should be postponed till to gaining of higher level of experience.

    TERT promoter C228T and C250T mutations occur in various malignancies including bladder cancer (BC) and may serve as urinary tumor markers. However, the mutation association with clinical variables in upper tract urothelial carcinomas (UTUCs) is unclear. There is also a lack of sensitive tools to detect the minor mutant TERT promoter in bulk urinary DNA. Here we analyzed 220 UTUC patients [98 with renal pelvic carcinoma (RPC) and 122 with ureter carcinoma (UC)] and developed a Competitive Allele-Specific TaqMan PCR (castPCR) for urinary assay. We identified C228T or C250T mutations in 42 of 98 (43%) RPC and 23 of 122 (19%) UC tumors. Distant metastases were significantly correlated with UTUC patients harboring TERT promoter mutations (P = 0.001). C228T were detected in 6/10 and 9/10 of urine samples from patients with mutation-carrying tumors using Sanger sequencing and castPCR, respectively. When urine samples from 70 BC patients were analyzed together, the sensitivity of urinary C228T assay was 89% and 50% for castPCR and Sanger sequencing, respectively (P < 0.001). Collectively, TERT promoter mutations occur in UTUCs with a high frequency in RPCs and predict distant metastasis. castPCR assays of the mutation are a useful tool for urine-based diagnostics of urological malignancies.

    Acute renal failure due to bilateral ureteral obstruction is a rare complication after appendectomy in children. We report a case of bilateral ureteric obstruction in a 14-year-old boy nine days after surgery for an acute appendicitis. After saline-filling of the urinary bladder, transabdominal ultrasound demonstrated bilateral hydronephrosis of moderate degree. No abscess was found with CT but presence of millimetric stones on both distal ureters was shown, with bilateral calyceal dilatation. Cystoscopy revealed inflammatory changes in the bladder base. Following introduction of bilateral ureteric stents, there was rapid normalisation of urinary output and serum creatinine. PMID:26295001

    Neurons in the pontomedullary reticular formation (PMRF) give rise to the reticulospinal tract. The motor output of the PMRF was investigated using stimulus-triggered averaging of electromyography (EMG) and force recordings in two monkeys (M. fascicularis). EMG was recorded from 12 pairs of upper limb muscles, and forces were detected using two isometric force-sensitive handles. Of 150 stimulation sites, 105 (70.0%) produced significant force responses, and 139 (92.5%) produced significant EMG responses. Based on the average flexor EMG onset latency of 8.3 ms and average force onset latency of 15.9 ms poststimulation, an electromechanical delay of ∼7.6 ms was calculated. The magnitude of force responses (∼10 mN) was correlated with the average change in EMG activity (P < 0.001). A multivariate linear regression analysis was used to estimate the contribution of each muscle to force generation, with flexors and extensors exhibiting antagonistic effects. A predominant force output pattern of ipsilateral flexion and contralateral extension was observed in response to PMRF stimulation, with 65.3% of significant ipsilateral force responses directed medially and posteriorly (P < 0.001) and 78.6% of contralateral responses directed laterally and anteriorly (P < 0.001). This novel approach permits direct measurement of force outputs evoked by central nervous system microstimulation. Despite the small magnitude of poststimulus EMG effects, low-intensity single-pulse microstimulation of the PMRF evoked detectable forces. The forces, showing the combined effect of all muscle activity in the arms, are consistent with reciprocal pattern of force outputs from the PMRF detectable with stimulus-triggered averaging of EMG.

    Bilateral transtibial amputee (BTA) gait has been investigated less and is not as well understood compared to that of their unilateral counterparts. Relative to able-bodied individuals, BTAs walk with reduced self-selected speeds, increased step width, hip-hiking, and greater metabolic cost. The clinically observed upper body motions of these individuals have not been quantified, but appear substantially different from able-bodied ambulators and may impact upright balance. Therefore, the objective of this study was to characterize the upper extremity kinematics of BTAs during steady-state walking. We measured medial-lateral ground reaction forces, step width and extrapolated center-of-mass (XCoM) trajectory, and observed effects of walking speed and increased prosthetic ankle range-of-motion (ROM) on these parameters. Significantly, BTAs display greater lateral trunk flexion ROM and shoulder abduction than able-bodied individuals when walking at similar speeds, and the inclusion of prosthetic adaptors for increasing passive ankle ROM slightly reduced step width. Overall, exaggerated lateral trunk flexion ROM was invariant with step width. Results suggest that lateral trunk motion is useful for shifting the body center-of-mass laterally onto the leading stance limb while simultaneously unloading the trailing limb. However, exaggerated lateral trunk flexion may introduce an unstable scenario if the XCoM is displaced beyond the lateral base-of-support. Further studies would be useful to identify if either prostheses that assist limb advancement and/or gait training may be effective in reducing this lateral sway while still maintaining efficient ambulation.

    Purpose. To investigate a novel computed method to reconstruct the bilateral digital interarticular channel of atlas and its potential use on the anterior upper cervical screw fixation. Methods. We have used the reverse engineering software (image-processing software and computer-aided design software) to create the approximate and optimal digital interarticular channel of atlas for 60 participants. Angles of channels, diameters of inscribed circles, long and short axes of ellipses were measured and recorded, and gender-specific analysis was also performed. Results. The channels provided sufficient space for one or two screws, and the parameters of channels are described. While the channels of females were smaller than that of males, no significant difference of angles between males and females were observed. Conclusion. Our study demonstrates the radiological features of approximate digital interarticular channels, optimal digital interarticular channels of atlas, and provides the reference trajectory of anterior transarticular screws and anterior occiput-to-axis screws. Additionally, we provide a protocol that can help make a pre-operative plan for accurate placement of anterior transarticular screws and anterior occiput-to-axis screws. PMID:26925345

    Objectives To prospectively compare the diagnostic performance and the visualization of the upper urinary tract (UUT) using a comprehensive 3.0T- magnetic resonance urography (MRU) protocol versus triple-phase computed tomography urography (CTU). Methods During the study period (January-2014 through December-2015), all consecutive patients in our tertiary university hospital scheduled by a urologist for CTU to exclude UUT malignancy were invited to participate. Diagnostic performance and visualization scores of 3.0T-MRU were compared to CTU using Wilcoxon matched-pairs test. Results Twenty patients (39 UUT excreting units) were evaluated. 3.0T-MRU and CTU achieved equal diagnostic performances. The benign etiology of seven UUT obstructions was clarified equally with both methods. Another two urinary tract malignant tumors and one benign extraurinary tumor were detected and confirmed. Diagnostic visualization was slightly better in the intrarenal cavity areas with CTU but worsened towards distal ureter. MRU showed consistently slightly better visualization of the ureter. In the comparison, full 100% visualizations were detected in all areas in 93.6% (with 3.0T-MRU) and 87.2% (with CTU) and >75% visualization in 100% (3.0T-MRU) and 93.6% (CTU). Mean CTU effective radiation dose was 9.2 mSv. Conclusions Comprehensive 3.0T-MRU is an accurate imaging modality achieving comparable performance with CTU; since it does not entail exposure to radiation, it has the potential to become the primary investigation technique in selected patients.

    The objective of this study was to assess the value of dual X-ray absorptiometry (DXA) in comparison to non contrast computed tomography (NCCT) density as possible predictors of upper urinary tract stone disintegration by shock wave lithotripsy (SWL). This study included 100 consecutive patients, with solitary renal stone 0.5-2 cm or upper ureteral stone up to 1 cm. DXA to calculate stone mineral density (SMD) and stone mineral content (SMC) was done. NCCT was performed to measure Hounsfield units (HU). SWL was performed with an electromagnetic lithotripsy, plain X-ray documented disintegration after SWL. Successful treatment was defined as stone free or complete fragmentation after 1 or 2 sessions of SWL. The impact of patients age, sex, body mass index, stone laterality, location, volume, length, mean SMC and SMD, HU and Hounsfield density (HD), skin to stone distance (SSD) and number of shock waves were evaluated by univariate and multivariate analysis. Only 76 patients were available for follow-up. Success of disintegration was observed in 50 out of 76 patients (65.8 %). On multivariate analysis, SMC and number of shock wave were the significant independent factors affecting SWL outcome (p = 0.04 and p = 0.000, respectively). SMC as detected by DXA is a significant predictor of success of stone disintegration by SWL. SMC measured by DXA is more accurate than HU measured by CT. Patients with high stone mineral content (SMC greater than 0.65 g) should be directly offered another treatment option.

    Purpose Surgical management of upper tract urothelial carcinoma requires removal of kidney and ureter, compromising renal function. Non-surgical alternatives have potentially prohibitive safety concerns. We examine the feasibility and safety of ablation of the ureter and renal pelvis using endoluminal vascular-targeted photodynamic therapy in a porcine model and report efficacy of WST11 vascular-targeted photodynamic therapy in a murine model. Materials and Methods Following approval, we performed 28 endoluminal ablations in the ureters and renal pelvis of 18 swine. Intravenous infusion of WST11 (4mg/kg) followed by laser illumination (10 minutes) was performed via percutaneous access or retrograde ureteroscopic approach. Animals were followed clinically with laboratory testing, imaging and histology was evaluated at several post-ablation time points. A murine xenograft was created with the 5637 human urothelial cell carcinoma line to determine sensitivity to this therapy. Results At 24 hours, 50 mW/cm laser fluence produced superficial necrosis of the ureter and deeper necrosis (penetrating the muscularis propria or adventitia) was produced by treatment with 200 mW/cm in the ureter and renal pelvis. At 4 weeks, superficial urothelium had regenerated over the treatment site. No symptomatic obstruction, clinically relevant hydronephrosis, or abnormality of lab testing was noted up to 4 weeks. In mice, 80% had no evidence of tumor at 19 days after WST11 vascular-targeted photodynamic therapy. Conclusions Urothelial cell carcinoma appears to be sensitive to WST11 vascular-targeted photodynamic therapy. Depth of WST11 vascular-targeted photodynamic therapy treatment effects can be modulated in a dose-dependent manner by titration of light intensity. Moreover, this treatment modality, applied to the porcine upper urinary tract, is feasible via antegrade and retrograde access. PMID:26860792

    Arsenic exposure and cigarette smoking are environmental risk factors for urothelial carcinoma (UC). Vascular endothelial growth factor (VEGF) is the key regulator of angiogenesis in various malignancies. This study investigates the joint effect of arsenic exposure, cigarette smoking, and VEGF polymorphisms on UC risk. This was a hospital-based case-control study consisting of 730 histopathologically confirmed UC cases, including 470 bladder cancers, 260 upper urinary tract UCs (UUTUCs), and 850 age-matched controls, recruited from September 1998 to December 2009. UC risk was estimated by odds ratios and 95% confidence intervals using unconditional logistic regression. Ever smokers with high arsenic exposure had significantly increased risks of 5.7 and 6.4 for bladder cancer and UUTUC, respectively. Moreover, ever smokers with high arsenic exposure carrying 1 or 2 risk genotypes of the VEGF gene had a significantly increased risk of 6.6 for bladder cancer and a strikingly higher risk of 9.9 for UUTUC. Additionally, UUTUC cases with high arsenic exposure carrying 1 or 2 risk genotypes of the VEGF gene had a non-significant increased risk of advanced tumor stage. Our findings suggest that arsenic exposure, cigarette smoking, and risk genotypes of VEGF contribute to a higher risk of UUTUC than of bladder cancer.

    Upper urinary tract urothelial carcinoma (UT-UC) is rare and treatment options or prognostic markers are limited. There is increasing evidence indicating that urothelial carcinoma may be an endocrine-related cancer. The aim of this study was to analyze the prognostic effect of estrogen receptor beta (ERβ) on the outcome of UT-UC. From 2005 to 2012, this study included 105 patients with pT3 UT-UC. Perioperative factors, pathological features, and ERβ immunostaining were reviewed and prognostic effects were examined by multivariate analysis. This study divided patients into either the ERβ-high (n = 52) or ERβ-low (n = 53) group and analyzed their oncologic outcomes. All pathological features except infiltrating tumor architecture (significantly higher incidence in ERβ-low group, p = 0.004) are symmetric in both groups. Low ERβ expression was significantly correlated with local recurrence and distant metastasis in univariate analysis (p = 0.035 and 0.004, respectively) and multivariate analysis (p = 0.05 and 0.008, respectively). Cell line study also proved that knock down of ERβ cause less UTUC proliferation and migration. In addition, ERβ agonist also enhanced the cytotoxic and migration inhibition effect of cisplatin and ERβ antagonist cause the UTUC cell more resistant to cisplatin. This result may help identify patients in need of adjuvant therapy or develop potential targeted therapy. PMID:27052470

    The thulium laser (Tm-laser) technique has been used in the management of many urologic conditions. The present study aimed to evaluate the use of this technique for distal ureter and bladder cuff (DUBC) excision during nephroureterectomy for upper urinary tract urothelial carcinoma (UUT-UC). Fifty-eight patients with UUT-UC who underwent radical nephroureterectomy were included in this retrospective study. DUBC was managed by open excision in 24 cases, by transurethral electrosurgery in 17 cases, and by transurethral Tm-laser in 17 cases. Perioperative measures and oncologic outcomes were compared among the three groups. Furthermore, 11 human ureteral segments were collected to measure the burst pressure and show physical pressure tolerance, and six ureteral segments were assessed histologically to investigate the sealing effect. Operative time and hospital stay were significantly longer, and intraoperative blood loss was significantly greater in the open excision group than in the electrosurgery and Tm-laser groups (P < 0.05 for all). There were no significant differences in these parameters between the electrosurgery and Tm-laser groups. In addition, there were no significant differences in the incidences of bladder tumors and retroperitoneal recurrence of urothelial carcinoma among the three groups. The coagulation time and resection time were significantly shorter in the Tm-laser group than in the electrosurgery group. The mean burst pressure did not differ significantly between the tissues sealed by electrosurgery and by Tm-laser. Histopathological analyses showed that distal ureters were completely sealed by both electrosurgery and Tm-laser. The Tm-laser technique is superior to open excision and comparable to transurethral electrosurgery in the management of DUBC during nephroureterectomy for UUT-UC, offering an alternative treatment option for this condition.

    Numerous studies have reported an association between end-stage renal disease (ESRD) and malignancy. The predominant malignant tumor that occurs in patients with ESRD in Asian countries is urothelial carcinoma (UC). According to recent research, cases of UC in dialysis-dependent patients are associated with higher recurrence rates and more aggressive biological behavior compared with patients without ESRD. The necessity of 1-step total urinary tract exenteration for dialysis-dependent patients with UC is advocated by certain studies. The current study reports a case of metachronous bladder cancer and bilateral upper urinary tract tumor in a dialysis-dependent patient. Three separate surgeries were performed to remove the bladder, and left and right urinary tract, respectively. The question of whether the stepwise strategy or the 1-step surgery should be selected for such special cases remains in debate. PMID:27313734

  3. Bilateral vestibulopathy.

    PubMed

    2016-01-01

    The leading symptoms of bilateral vestibulopathy (BVP) are postural imbalance and unsteadiness of gait that worsens in darkness and on uneven ground. There are typically no symptoms while sitting or lying under static conditions. A minority of patients also have movement-induced oscillopsia, in particular while walking. The diagnosis of BVP is based on a bilaterally reduced or absent function of the vestibulo-ocular reflex (VOR). This deficit is diagnosed for the high-frequency range of the angular VOR by a bilaterally pathologic bedside head impulse test (HIT) and for the low-frequency range by a bilaterally reduced or absent caloric response. If the results of the bedside HIT are unclear, angular VOR function should be quantified by a video-oculography system (vHIT). An additional test supporting the diagnosis is dynamic visual acuity. Cervical and ocular vestibular-evoked myogenic potentials (c/oVEMP) may also be reduced or absent, indicating impaired otolith function. There are different subtypes of BVP depending on the affected anatomic structure and frequency range of the VOR deficit: impaired canal function in the low- and/or high-frequency VOR range only and/or otolith function only; the latter is very rare. The etiology of BVP remains unclear in more than 50% of patients: in these cases neurodegeneration is assumed. Frequent known causes are ototoxicity mainly due to gentamicin, bilateral Menière's disease, autoimmune diseases, meningitis and bilateral vestibular schwannoma, as well as an association with cerebellar degeneration (cerebellar ataxia, neuropathy, vestibular areflexia syndrome=CANVAS). In general, in the long term there is no improvement of vestibular function. There are four treatment options: first, detailed patient counseling to explain the cause, etiology, and consequences, as well as the course of the disease; second, daily vestibular exercises and balance training; third, if possible, treatment of the underlying cause, as in bilateral

    The aim of this study was to evaluate the clinical value of the PolyScope™ endoscope system in the treatment of upper urinary calculi with a diameter of <2 cm. A total of 86 patients hospitalized with upper urinary tract calculi were included. The patients were placed under general or spinal anesthesia and in a lithotomy position. Following the dilation of the ureter, a guide wire was inserted under the direct vision of an F8/9.8 rigid ureteroscope, and an F12/14 flexible ureteral access sheath was positioned along the guide wire. Holmium laser lithotripsy was subsequently performed, using an F8.0 'PolyScope' modular flexible ureteroscope. Plain film of the kidney-ureter-bladder (KUB) was performed 1 day subsequent to the surgery, in order to determine the result of the lithotripsy and the position of the double-J stent which was inserted after after holmium laser lithotripsy. In addition, in certain patients, KUB radiography was performed 2-4 weeks subsequent to the surgery, and extracorporeal shockwave lithotripsy (ESWL) was performed if the diameter of the residual stones was >6 mm. Lithotripsy was successful in 77 patients and the duration of the surgery ranged between 25 and 80 min (mean duration, 42 min). Little bleeding was observed. Three patients presented with a slight fever following the surgery; however, no ureteral perforation, high fever or septicemia was observed among the patients following anti-inflammatory treatment. The stone-free rate (SFR) of the single-pass lithotripsy was 89.5% (77/86) and the SFR with ESWL was 96.5% (83/86). The study demonstrated that the F8 modular flexible ureteroscope was safe, convenient and effective for the lithotripsy of upper-tract calculi.

    Clinical presentation helps differentiate between upper and lower urinary tract infections (UTIs). UTIs are classified as either complicated or uncomplicated. A complicated UTI is associated with an underlying condition that increases the risk of failing therapy. Primary laboratory tests for UTIs consist of urinalysis and urine culture. The most common pathogen for uncomplicated cystitis and pyelonephritis is Escherichia coli. Nitrofurantoin, fosfomycin, and trimethoprim-sulfamethoxazole are first-line therapies for acute uncomplicated cystitis. Decisions regarding antibiotic agents should be individualized based on patients' allergies, tolerability, community resistance rates, cost, and availability.

    We report on a 13-year-old patient followed since birth. He is the only offspring of young, non-consanguineous German parents. His mother has an isolated left cleft of lip and a cleft palate. At birth, our patient presented with bilaterally cleft lip/cleft palate, phocomelia of upper limbs with normal hands, and mild symmetrical deficiencies of the long bones of the lower limbs. Haematological evaluation demonstrated a leukaemoid reaction during a urinary tract infection as well as intermittent thrombocytopenia and episodes of marked eosinophilia during the first two years of life. Intellectual development has been normal. Comparison with two similar cases from the literature suggests a non-random phenotypic overlap of Roberts syndrome (MIM 268300) and TAR syndrome (MIM 274000). Such clinical constellations may be key observations to understand the genetic relationship of Roberts syndrome and TAR syndrome in future phenotype-genotype correlations. PMID:9788553

    The aim of this study is to compare the clinical efficacy and safety of retroperitoneal laparoscopic ureterolithotomy (RPLU) and ureteroscopic holmium laser lithotripsy (UHLL) as two minimally invasive procedures in managing obstructive upper ureteral calculi with concurrent urinary tract infections (UTI). The retrospective study included 189 patients who underwent unilateral obstructive upper ureteral stones with concurrent UTI from January 2007 to November 2014 at our institution. Patients received RPLU (81 cases) or UHLL (108 cases). All patients received preoperative anti-infection treatment (indwelling ureteral stent and/or preoperative antibiotics). Collected data, including sex, age, stone size, success rate, operation duration, post-operation hospitalization time, and post-operation complications, were compared. All patients were followed up for more than 6 months after surgeries, and no ureterostenosis occurred. The study included 189 patients, 41 (21.7 %) females and 148 (78.3 %) males with a medium age of 52 years (range 22-81 years). All surgeries were successfully performed without conversion to open surgery. Stone size in the RPLU group was larger than that of the UHLL group (16.1 ± 1.4 vs. 10.4 ± 1.6 mm, P = 0.012). Operative duration (P = 0.009) and hospitalization time (P < 0.001) in the UHLL group were significantly shorter than those in the RPLU group, whereas stone clearance rate was significantly higher in the RPLU group (100 vs. 88.9 %, P = 0.002). Of note, postoperative fever was more common in patients treated with UHLL (15 cases) versus RPLU (4 cases) (13.9 vs. 4.9 %, P = 0.043). Moreover, in the UHLL group, three patients without a preoperative indwelling ureteral stent were complicated with sepsis, which was not seen in RPLU group. In our study, the safety and stone clearance rate of RPLU are better than those of UHLL in the treatment of unilateral upper ureteric calculi with concurrent UTI

    The aim of this study is to compare the clinical efficacy and safety of retroperitoneal laparoscopic ureterolithotomy (RPLU) and ureteroscopic holmium laser lithotripsy (UHLL) as two minimally invasive procedures in managing obstructive upper ureteral calculi with concurrent urinary tract infections (UTI). The retrospective study included 189 patients who underwent unilateral obstructive upper ureteral stones with concurrent UTI from January 2007 to November 2014 at our institution. Patients received RPLU (81 cases) or UHLL (108 cases). All patients received preoperative anti-infection treatment (indwelling ureteral stent and/or preoperative antibiotics). Collected data, including sex, age, stone size, success rate, operation duration, post-operation hospitalization time, and post-operation complications, were compared. All patients were followed up for more than 6 months after surgeries, and no ureterostenosis occurred. The study included 189 patients, 41 (21.7 %) females and 148 (78.3 %) males with a medium age of 52 years (range 22-81 years). All surgeries were successfully performed without conversion to open surgery. Stone size in the RPLU group was larger than that of the UHLL group (16.1 ± 1.4 vs. 10.4 ± 1.6 mm, P = 0.012). Operative duration (P = 0.009) and hospitalization time (P < 0.001) in the UHLL group were significantly shorter than those in the RPLU group, whereas stone clearance rate was significantly higher in the RPLU group (100 vs. 88.9 %, P = 0.002). Of note, postoperative fever was more common in patients treated with UHLL (15 cases) versus RPLU (4 cases) (13.9 vs. 4.9 %, P = 0.043). Moreover, in the UHLL group, three patients without a preoperative indwelling ureteral stent were complicated with sepsis, which was not seen in RPLU group. In our study, the safety and stone clearance rate of RPLU are better than those of UHLL in the treatment of unilateral upper ureteric calculi with concurrent UTI

    A short account is given of present views on urinary schistosomiasis or bilharziasis. The incidence of infections is increasing in endemic areas of Africa and the near east, as a consequence of irrigation programs and hydroelectric power development. Urinary schistosomiasis is a disease of children and young adults. The serious consequences, obstructive uropathy due to more or less irreversible ureteral lesions, and cancer of the bladder, less directly related to the infection, appear but later in life. Diagnosis is still based on parasitology and serology but ultrasonography has proven to be an important means to evaluate the extent of lesions of the urinary tract, especially in developing countries. Praziquantel was a major development in the medical treatment and cures easily the infection. Some irreversible consequences have however to be treated surgically. Schistosomiasis is still an important cause of morbidity and mortality in medically backward endemic countries. The control of the disease aims at reducing morbidity and mortality, consequences of the infection, rather than to avoid infection itself. It is based on mass treatment of school age children, together with focal molluscacides at places where people have contacts with water. Vaccination will be available in the near future and will be a welcome addition to other control measures, but will not be able to interrupt transmission on its own. Only economic development will solve in the long term this social African problem. PMID:1492630

    Approximately 10% of all stone patients require an endoscopic stone treatment. With the advent of laserlithotripters a new technology became available, featuring extremely thin (200 microns) and flexible lithotripsy probes. As a consequence, miniscopes have been developed for endoscopic stone manipulation in the ureter. These miniscopes greatly facilitate ureteroscopy and expectantly will reduce complications associated with this procedure. The success rates of laserlithotripsy are in the 90% range, the only serious drawback are the high purchase costs of the laser. Independent from these new possibilities for intracorporeal lithotripsy, extracorporeal shockwave lithotripsy (ESWL) remains the first therapy of choice for ureteral calculi.

    Since 1981, 525 renal and ureteric calculi have been removed with percutaneous nephrolithotomy (PCN) or transurethral ureteroscopy as the primary modalities of therapy. Successful extraction of the stone at the first attempt was achieved in 92 per cent of cases by PCN and 70 per cent of cases by ureteroscopy, whilst further endoscopic surgery improved the overall success rates to 98 per cent and to 80 per cent respectively. Complication rates from these procedures have both been low as has the morbidity, with most patients leaving hospital within 4 days and returning to work within 2 weeks. The successful development of endoscopic lithotomy and the use of in situ destruction techniques has meant that we now reserve open surgery for difficult multibranched staghorn calculi and ureteric stones embedded in the urothelium. With the advent of extracorporeally generated shockwave lithotripsy it is likely that even these types of stone will be amenable to minimally invasive procedures.

    Introduction: Unilateral anterior shoulder dislocation is one of the most common problems encountered in orthopedic practice. However, simultaneous bilateral anterior dislocation of the shoulders is quite rare. Case Presentation: We report a case of a 75-year-old woman presented with simultaneous bilateral anterior shoulder dislocation following a trauma, complicated with a traction injury to the posterior cord of the brachial plexus. Conclusions: Bilateral anterior shoulder dislocation is very rare. The excessive traction force during closed reduction may lead to nerve palsy. Clear documentation of neurovascular status and adequate imaging before and after a reduction should be performed. PMID:25685749

    The bilateral operculum syndrome, is a unique developmental syndrome. It is characterized by spastic paralysis of the muscles of the face, pharynx, and of mastication, as well as by epilepsy and mental retardation. Imaging studies show bilateral, structural abnormalities in the frontal, perisylvian region consistent with polymicrogyria. These children are usually diagnosed as suffering from cerebral palsy, but in the bilateral operculum syndrome, intelligence is relatively preserved despite the severe motor involvement. Misdiagnosis may lead to improper estimation of rehabilitation potential preventing appropriate therapy, especially in the field of alternative communication. We present a 3-year-old boy, apparently the first case of this syndrome to be described in Israel. PMID:8940497

The patient had a 30-year history of hypertension and paroxysmal atrial fibrillation. Computed tomography and magnetic resonance imaging showed heterogeneous tumors in bilateral adrenal glands and an enlarged para-aortic lymph node. Hormonal examinations revealed a high value of urinary catecholamines. Metaiodobenzylguanidine (MIBG) scintigraphy showed increased uptake in bilateral adrenal glands and the lymph node. Both adrenal tumors and the node were surgically removed. Pathological examination revealed histologically distinct tissue between the two adrenal tumors. The patient received five cycles of adjuvant chemotherapy, consisting of cyclophosphamide, vincristine, and dacarbazine. The patient has been in remission for 32 months following surgical treatment.

  8. Echinoderms Have Bilateral Tendencies

    2012-01-01

    Echinoderms take many forms of symmetry. Pentameral symmetry is the major form and the other forms are derived from it. However, the ancestors of echinoderms, which originated from Cambrian period, were believed to be bilaterians. Echinoderm larvae are bilateral during their early development. During embryonic development of starfish and sea urchins, the position and the developmental sequence of each arm are fixed, implying an auxological anterior/posterior axis. Starfish also possess the Hox gene cluster, which controls symmetrical development. Overall, echinoderms are thought to have a bilateral developmental mechanism and process. In this article, we focused on adult starfish behaviors to corroborate its bilateral tendency. We weighed their central disk and each arm to measure the position of the center of gravity. We then studied their turning-over behavior, crawling behavior and fleeing behavior statistically to obtain the center of frequency of each behavior. By joining the center of gravity and each center of frequency, we obtained three behavioral symmetric planes. These behavioral bilateral tendencies might be related to the A/P axis during the embryonic development of the starfish. It is very likely that the adult starfish is, to some extent, bilaterian because it displays some bilateral propensity and has a definite behavioral symmetric plane. The remainder of bilateral symmetry may have benefited echinoderms during their evolution from the Cambrian period to the present. PMID:22247765

    After urinary diversion patients are at increased risk of long-term complications, including stones of the upper urinary tract and reservoir or conduit. Advances in instrumentation and techniques have expanded treatment options, while minimizing morbidity. Minimally invasive treatment methods include shockwave lithotripsy, antegrade and retrograde ureteroscopic lithotripsy and percutaneous nephrolithotomy. Percutaneous and laparoscopic techniques are applicable to stones within urinary diversions. Medical management is crucial for avoiding recurrent stones in these patients.

    Congenital bladder diverticulum (CBD) is a very uncommon entity in adults. CBD could be unilateral or bilateral and is caused by a congenital weakness in the bladder musculature. CBD is differentiated from the paraureteral or Hutch type of diverticula. A 42-year-old male presented with bilateral Hutch diverticulum and multiple diverticulum calculus on intravenous pyelography. Cystoscopy revealed bladder diverticulum just medial to the left ureteral orifice with multiple calculi; the patient successfully underwent endoscopic laser cystolithotripsy with resolution of his urinary tract infection. To the best of our knowledge, this is the first case report presenting stone formation of CBD in an adult. PMID:26029313

    Simultaneous or subsequent bilateral thalamic haemorrhage is rare, and most reported cases are from Asian countries. An 80-year-old white Cuban man, with a history of arterial hypertension, suffered sudden onset of right hemiparesis. Computed tomography (CT) scan showed a left posteromedial thalamic haemorrhage. Two days later his condition suddenly deteriorated: blood pressure was 220/105 mm Hg, he was stuporous and tetraplegic, respiration was ataxic, and his gaze was fixed and deviated downward and inward. CT scan showed haemorrhages in both thalami, extending to the ventricles. 32 h later the patient died. There are few previous publications of simultaneous or subsequent bilateral thalamic haemorrhages and this is the first report involving a Hispanic patient. Prognosis in patients with bilateral thalamic haemorrhage is poor, and the mechanism underlying the development of subsequent and symmetrical bleeding is not clear. PMID:21709830

    Patients with bilateral urolithiasis diagnosed at their first visit were followed for at least one year after the start of treatment. In this retrospective study of 123 patients, the basic metabolic workup revealed no specific underlying cause of simultaneously occurring bilateral nephrolithiasis, and none of the currently used therapeutic regimes proved to be efficient in attaining clinically acceptable stone-free rates at the 3, 6 and 12-month follow-ups. Of 38 patients treated with extracorporeal shockwave lithotripsy (SWL), 21 underwent treatment of both kidneys and 10 (48%) were free of stones bilaterally after 12 months. All of the 17 patients treated with unilateral SWL failed to achieve a stone-free state on the contralateral side. In another group, treated with medication alone to minimize risks of stone recurrence, only 3 of 26 (11.5%) patients were stone-free on both sides 12 months after the start of medication. Since we achieved a stone-free state of both kidneys in no more than 12% of the non-medicated cases, it seems warranted to treat bilateral urolithiasis with SWL more frequently, particularly when patients cannot return regularly to the stone clinic for a longterm follow-up.

    1993-01-01

    The management of boys with undescended testes appears to be an increasingly common problem. While Scorer (1964) [11] reported an incidence of 0.8% of undescended testes in boys of one year of age, a recent survey (Radcliffe Hospital, Oxford, 1986) [18] suggests the incidence has risen to as high as 1.6%. While the etiology may be varied, it is quite clear that many cases represent disturbances of the hypothalamic-pituitary-gonadal axis and may represent a forme fruste of hypogonadotropic hypogonadism [3]. Bilateral undescended testes might logically appear to represent the worst end of such an endocrinopathy. Indeed, a review of the experience at The Children's Hospital of Philadelphia [12] of boys with bilateral undescended testes indicated a greater number of CNS abnormalities (P = 0.0000) than in boys with unilateral undescended testes (Table 1). Also consistent with bilateral cryptorchid testes representing the most severe end of the spectrum was the reported findings from that study that bilateral undescended testes also exhibit a significantly greater number of associated G-U anomalies (P = 0.0004).

Presentation of the case A young adult presented to our clinic after being referred from primary care clinic with intermittent bilateral flank pain and no other symptoms after extensive radiological investigations diagnosis has been made and confirmed by radiological finding of disease. Active treatment usually preserved for complex cases and for the complications of the disease but in our patient as needed analgesia worked well in controlling his intermittent pain and his wish not to pursue any intervention. The vague presentation with initial imaging rising suspicion of renal tumor or complex renal cyst might cause psychological street on the patient, which our patient had, but reassurance after extensive radiological work up relive that's stress. Discussion Although it is very rare disease to be bilateral but wide variety of other differential diagnoses make importance of disease recognition and accurate diagnosis is the key. Conclusion Renal lymphangiomatosis is a rare benign disease of renal lymphatic, which usually affect one side, but bilateral form is very rare form, which may raise the suspicions of genetic form of renal malignancy. Accurate diagnosis requires work up to role out malignant and other renal tumor, which require active surgical management. PMID:26719997

    Purpose: To describe a case of bilateral presumed tuberculous choroiditis which resolved promptly with a short course of antituberculous therapy. Case Report: A 44-year-old lady presented with bilateral visual loss of 8 months’duration. Considering the presence of pan-uveitis, severe macular edema, multifocal leakage on fluorescein angiography, positive tuberculin skin test, and after excluding other diseases, she underwent anti-tuberculous therapy (ATT) for disseminated choroiditis due to presumed ocular tuberculosis. She improved promptly and completely. There were no signs of relapse 18 months after completion of the treatment course. In a young patient with disseminated choroiditis and relatively short duration of symptoms, a course of ATT for 6 months may effectively treat the disease preventing relapse for a considerable period of time. Conclusion: In Presumed Tuberculous chroiditis early diagnosis is crucial for prompt and complete improvement. PMID:27413507

    Williams, C

    1980-09-01

    We are reporting what we believe to be the second case of bilateral parotid neoplasm occuring synchronously with differing histologies. We believe that this neoplasm may represent a specific propensity of parotid tissue in a given individual to develop neoplasia in a multipotential glandular organ subject to many neoplastic diseases. There also exists the possibility that this condition may represent an immune deficiency specific to the parotid gland. The case reports that have been reviewed demonstrate that a secondary neoplasm may arise from benign mixed tumors. We question whether this is an example of monistic origin of acinic cell tumor from a mixed-cell tumor or, perhaps, dualistic expression for this salivary gland to develop a multiplicity of anaplastic and metaplastic growth variants. In approaching a case with bilateral parotid involvement, the physician must be aware of the rare possibility that benign and malignant tumors may coexist. He must be prepared to proceed with more radical extirpation than simple superficial parotidectomy.

  5. Multispectral bilateral video fusion.

    Bennett, Eric P; Mason, John L; McMillan, Leonard

    2007-05-01

    We present a technique for enhancing underexposed visible-spectrum video by fusing it with simultaneously captured video from sensors in nonvisible spectra, such as Short Wave IR or Near IR. Although IR sensors can accurately capture video in low-light and night-vision applications, they lack the color and relative luminances of visible-spectrum sensors. RGB sensors do capture color and correct relative luminances, but are underexposed, noisy, and lack fine features due to short video exposure times. Our enhanced fusion output is a reconstruction of the RGB input assisted by the IR data, not an incorporation of elements imaged only in IR. With a temporal noise reduction, we first remove shot noise and increase the color accuracy of the RGB footage. The IR video is then normalized to ensure cross-spectral compatibility with the visible-spectrum video using ratio images. To aid fusion, we decompose the video sources with edge-preserving filters. We introduce a multispectral version of the bilateral filter called the "dual bilateral" that robustly decomposes the RGB video. It utilizes the less-noisy IR for edge detection but also preserves strong visible-spectrum edges not in the IR. We fuse the RGB low frequencies, the IR texture details, and the dual bilateral edges into a noise-reduced video with sharp details, correct chrominances, and natural relative luminances.

    Spontaneous rupture of the collecting system with extravasation of urine and urinoma formation is usually associated with urinary tract obstruction by a ureteral calculus. Tumor growth is an extremely rare cause of urinary extravasation. Here we report a case of bilateral obstructive uropathy with a huge spontaneous left retroperitoneal urinoma caused by advanced infiltrative transitional cell carcinoma of the urinary bladder. The point of leakage was located in the left renal pelvis. The urinary leakage ceased after percutaneous nephrostomy drainage, and the patient subsequently underwent radical cystoprostatectomy. Histopathology revealed a high-grade urothelial carcinoma of the urinary bladder with pelvic lymph node metastasis. The patient refused any adjuvant treatment and expired 6 months after the operation from disseminated metastasis from bladder cancer.

Although anatomical variations of the axillary artery are very common, the existence of a unilateral accessory thoracodorsal artery has been described in the literature only once. There are no reports of bilateral accessory thoracodorsal artery, in the literature. In the present study, a bilateral accessory thoracodorsal artery, originating on either side of the third part of the axillary artery, is described in a 68-year-old female cadaver. All the other branches of the axillary artery had a typical origin, course, distribution and termination. This extremely rare anatomical variation apart from the anatomical importance also has clinical significance for surgeons in this area. Especially, during the dissection or mobilization of the latissimus dorsi that is partly used for coverage problems in many regions of the body and also in dynamic cardiomyoplasty, any iatrogenic injury of this accessory artery may result in ischemia and functional loss of the graft.

    Wilms' tumor occurs in 5-10 % of all cases of nephroblastoma. The metachronous form represents 2-3 % of cases. Most (96.2 %) metachronous tumors appear within the first 5 years of the primary tumor. Associated malformations are more common in bilateral cases. Metachronous tumors are a therapeutic challenge. We describe the case of an 11-year-old girl with left hemihypertrophy. The diagnosis was metachronous relapse of Wilms' tumor 7 years after the first diagnosis. The patient received five courses of preoperative chemotherapy and tumorectomy was performed. Because of post-surgical complications, nephrectomy was performed on her only kidney. Since she is anephric, the patient is in chronic renal failure and is dependent on dialysis. Treatment with carboplatin and etoposide was continued after surgery and the patient is currently in complete remission. The appearance of a metachronous Wilms' tumor 5 years after that of the primary tumor is rare. When a contralateral tumour develops, chemotherapy must be given until the size of the tumor is reduced in order to preserve renal function and avoid dialysis. In patients with chronic renal failure caused by bilateral nephrectomy, ongoing treatment with dialysis support can be achieved through the choice of effective drugs and knowledge of their pharmacokinetics and pharmacodynamics.

    Urothelial carcinoma (UC) originated from renal pelvis is the common tumor of the urinary system, however, neoplasia of the renal pelvis in duplex kidneys is extremely rare, especially in the complete renal and ureteral duplex cases. We present the first case of renal pelvis UC of the upper moiety in a complete right renal duplex. This male patient has bilateral complete renal and ureteral duplex. To the best of our knowledge, this is the first reported case of renal pelvis UC in a complete renal duplex system. After this experience we feel that the diagnosis of renal pelvis UC in duplex kidneys is not so easy, and once the diagnosis is determined, the whole renal duplex units and bladder cuff or ectopic orifice should be excised radically.

    Acute emphysematous pyelonephritis (AEP) is a severe form of urinary tract infection. It occurs usually in diabetics. The most concerned agents are the Gram-negative bacilli. We report a first case of bilateral AEP due to Candida glabrata, occurred in a 64-year-old diabetic woman. The clinical presentation started with fever and abdominal pains, without signs of urinary tract infection. Within six hours, the patient had developed a septic shock with renal failure and ketoacidosis. The diagnosis was confirmed by CT scan and the pathogen was isolated in urine. Despite antibiotic and antifungal treatment, she died from a septic shock. Acute emphysematous pyelonephritis due to Candida species is rare. However, the addition of antifungal therapy seems justified if a severe emphysematous pyelonephritis is associated with risk factors of Candida infection.

    Bilateral ureteral obstruction in children is a rare condition arising from several medical or surgical pictures. It needs to be promptly suspected in order to attempt a quick renal function recovery. In this paper we concentrated on uncommon causes of obstruction, with the aim of giving a summary of such multiple, rare and heterogeneous conditions joint together by the common denominator of sudden bilateral ureteral obstruction, difficult to be suspected at times. Conversely, typical and well-known diseases have been just run over. We considered pediatric cases of ureteral obstruction presenting as bilateral, along with some cases which truly appeared as single-sided, because of their potential bilateral presentation. We performed a review of the literature by a search on PubMed, CrossRef Metadata Search, internet and reference lists of single articles updated to May 2014, with no time limits in the past. Given that we deal with rare conditions, we decided to include also papers in non-English languages, published with an English abstract. For the sake of clearness, we divided our research results into 8 categories: (1) urolithiasis; (2) congenital urinary tract malformations; (3) immuno-rheumatologic causes of ureteral obstruction; (4) ureteral localization of infections; (5) other systemic infective causes of ureteral obstructions; (6) neoplastic intrinsic ureteral obstructions; (7) extrinsic ureteral obstructions; and (8) iatrogenic trigonal obstruction or inflammation. Of course, different pathogenic mechanisms underlay those clinical pictures, partly well-known and partly not completely understood. PMID:25374811

    This article presents the clinical features of crystal arthropathy after knee replacement. The current literature on pseudogout and gout after both total and partial knee replacement is summarized. A case of bilateral pseudogout 8 years after initial total knee arthroplasty (TKA) is used to highlight the clinical characteristics and treatment options for this underrecognized condition. Presentation mimicked a late septic joint arthroplasty with sudden onset of pain and effusion. The patient was treated successfully with an arthrotomy, debridement, synovectomy, polyethylene insert exchange, oral steroids, and nonsteroidal anti-inflammatories. There are no other reported cases of bilateral pseudogout after bilateral TKA.

    symptoms are prolonged, then a seven day course of antibiotics should be given. Selected group of patients benefits from low-dose prophylactic therapy. Upper urinary tract infection may need in-patient treatment. Treatment of acute prostatitis is 30-day therapy of appropriate antibiotics and for chronic bacterial prostatitis a low dose therapy for 6-12 months may be required. It should be noted that no attempt should be made to eradicate infection unless foreign bodies such as stones and catheters are removed and correctable urological abnormalities are taken care of. Treatment under such circumstances can result only in the emergence of resistant organisms and complicate therapy further. PMID:20535247

    An eight-month-old Pekingese bitch with urinary incontinence was found to have three congenital anomalies of the urinary tract: left renal agenesis, bilateral ectopic ureters with a left cranial blind-ending ureter, and urinary bladder hypoplasia. The diagnoses were made by retrograde vaginourethrography, excretory urography, ultrasonography and duplex Doppler ultrasonography. Although urological anomalies associated with renal agenesis have been frequently observed, a cranial blind-end ectopic ureter has not, to the authors' knowledge, been described in the bitch. The dog was managed medically with a restricted protein diet because of a compromised unilateral kidney with hydronephrosis and hydroureter.

Methods: A 65-year-old male with bilateral decreased visual acuity for 3 weeks as well as bilateral hypoacusia, vertigo, disequilibrium, headache and decreased strength in the right upper limb for 4 months. The clinical work-up revealed a bilateral panuveitis and an ischemic cerebellar stroke. Result: The diagnosis of Whipple disease was confirmed by histopathological analysis of adenopathy. The patient was treated with cortico-antibiotic therapy with significant clinical improvement. Conclusion: Although rare, Whipple disease is potentially fatal if left untreated, it must be always be taken into consideration before any panuveitis of an unknown cause, even in the absence of gastrointestinal symptoms.

    Multiple symmetric lipomatosis (MSL), or Madelung's disease, is a rare disease of unknown etiology. It is characterized by the presence of loose adipose tissue deposits localized in the cervical region and upper body. MSL presenting as bilateral huge gynecomastia is an extremely rare phenomenon. The present report describes a case of MSL in a 66-year-old man. The patients presented with bilateral breast bulging. He had a history of cigarette and alcohol use. His condition was treated with a bilateral nipple-sparing mastectomy. MSL can present as a form of gynecomastia, for its accurate diagnosis and proper treatment of MSL, increasing awareness of the clinical characteristics of the disease is required, especially amongst breast surgeons. Herein, we review the literature and discuss the clinical characteristics, pathology, and surgical treatment of MSL. PMID:25548590

  6. Bilateral asymmetry of the humerus during growth and development.

    PubMed

    2011-08-01

    The development of handedness throughout growth can be investigated by using bilateral asymmetry of the humerus as a proxy for this trait. A large skeletal sample of nonadults from English archaeological sites was examined using standard metric techniques to assess when right-sided asymmetry first appears in the human skeleton. Results of this work indicate a change in directional asymmetry during growth and development, with infants and young children exhibiting no significant asymmetry and older children and adolescents demonstrating right-sidedness. This trend is consistent with what has been observed in previous studies of upper limb asymmetry in skeletal material and behaviorally in living children, adding further strength to the premise that biomechanical forces strongly influence bilateral asymmetry in the upper limb bones. Variability in the magnitude of asymmetry between different features of the humerus was also noted. This characteristic can be explained by differing degrees of genetic canalization, with length and articular dimensions being more strongly canalized than diaphyseal properties.

    Four patients, aged 7-20 years, suffered from recurrent episodes of flaccid paralysis and encephalopathy associated with bilateral striatal necrosis and chronic progressive polyneuropathy. Using homozygosity mapping, a pathogenic missense mutation in the SLC25A19 gene that encodes the mitochondrial thiamine pyrophosphate transporter was identified. An SLC25A19 mutation was previously reported in Amish congenital lethal microcephaly but the present patients' phenotype is markedly different, with normal head circumference, normal early childhood development, age-appropriate cognitive skills, and normal urinary organic acid profile. Determination of the SLC25A19 sequence should be considered in patients with bilateral striatal necrosis and progressive polyneuropathy. PMID:19798730

    Introduction Definite paucity of data pertaining to spectrum of renal and urinary tract diseases in our state and in various parts of India forms the basis of this study. Available data has emphasized more on specific clinical syndromes and chronic renal diseases rather than over all spectrums of renal and urinary tract diseases, that too in adult population. Aim The present study a retrospective analysis, forms one of the basic data of paediatric nephrology and urology related disorders in our state. Materials and Methods Retrospective analysis of the case records of all the hospitalized patients with renal and urinary tract diseases between 2012 and 2013 were performed. Case records were analysed and categorized into various groups like; Urinary Tract Infections (UTI), Acute Kidney Injury (AKI), Acute Glomerulonephritis (AGN), Nephrotic Syndrome (NS), haematuria, Polycystic Kidney Disease (PCKD), Posterior Urethral Valve (PUV), Vesicoureteric Reflux (VUR), Chronic Kidney Disease (CKD), Congenital Anomalies of Kidney and Urinary Iract (CAKUT) and others. These groups were divided into subgroups to get more insight about the pattern of these diseases. Results Out of 28114 patients hospitalized between 2012 and 2013 years, 447 (232 males and 215 females) patients were diagnosed of renal and urinary tract diseases which forms 1.58% the total admitted patients. Among these patients 32.9% (147/447) were diagnosed Acute Kidney Injury (AKI); 24.1% (108/447): Urinary Tract Infection (UTI); 9.6% (43/447): Acute Glomerulonephritis (AGN); 5.6% (25/447): bilateral hydronephrosis with UTI; 4.47% (20/447): nephrotic syndrome (NS); 3.5% (16/447): haematuria; and 4% (18/447) were having CAKUT (Congenital Anomalies Of Kidney And Urinary Tract). In addition to this there were 17 cases of Renal Tubular Acidosis (RTA), 3 cases of Barter syndrome and one case of Liddle syndrome.

    Several kinds of nonvascular interventional radiology of the urinary tract are reviewed. Transurethral balloon dilation of the prostate (TU-DP) is a newly developed nonsurgical treatment for benign prostate hyperplasia, which is performed under local anesthesia with minimal morbidity and requires no hospitalization. The TUDP technique involves dilating the prostatic urethra and bladder neck to 75 F for 10 minutes under fluoroscopic control using a high-pressure dilating balloon. Long-term follow-up studies are required. Percutaneous nephrolithotomy (PNL) and transurethral ureterolithotomy (TUL) have signified a revolution in stone surgery of upper urinary tract. Indications for these treatments, endoscopic manipulation, complications and their clinical features are presented. The procedure of PNL consists of 3 steps, puncture for nephrostomy tract, tract dilation and stone removal. Among these steps the most important is the puncture and it should be effected through the calyx. During the operation, if there is too much bleeding, it can be discontinued at any time while keeping the track open. It is no longer necessary for the kidney to be free of stones at the end of the operation. TUL is performed with a rigid or flexible ureterorenoscope. Dilation of the ureteral orifice and the intramural ureter is necessary for passing the scopes. When they have been sufficiently dilated, the ureterorenoscope can be passed to the level of the renal pelvis through the urethra. Calculi have been removed successfully at a higher rate in lower ureter. Endopyelotomy may be performed safely as an initial procedure to correct congenital obstruction of the ureteropelvic junction. Recent advancements have permitted an approach to percutaneous resection for renal pelvic tumor in a solitary kidney or bilateral synchronous disease. There are great expectations for continuing important innovations in the field of interventional radiology. PMID:2476077

    OBJECTIVE Markers reliably identifying vascular damage and risk in diabetic patients are rare, and reports on associations of serum adiponectin with macrovascular disease have been inconsistent. In contrast to existing data on serum adiponectin, this study assesses whether urinary adiponectin excretion might represent a more consistent vascular damage marker in type 2 diabetes. RESEARCH DESIGN AND METHODS Adiponectin distribution in human kidney biopsies was assessed by immunohistochemistry, and urinary adiponectin isoforms were characterized by Western blot analysis. Total urinary adiponectin excretion rate was measured in 156 patients with type 2 diabetes who had a history of diabetic nephropathy and 40 healthy control subjects using enzyme-linked immunosorbent assay. Atherosclerotic burden was assessed by common carotid artery intima-media-thickness (IMT). RESULTS A homogenous staining of adiponectin was found on the endothelial surface of glomerular capillaries and intrarenal arterioles in nondiabetic kidneys, whereas staining was decreased in diabetic nephropathy. Low-molecular adiponectin isoforms (∼30–70 kDa) were detected in urine by Western blot analysis. Urinary adiponectin was significantly increased in type 2 diabetes (7.68 ± 14.26 vs. control subjects: 2.91 ± 3.85 μg/g creatinine, P = 0.008). Among type 2 diabetic patients, adiponectinuria was associated with IMT (r = 0.479, P < 0.001) and proved to be a powerful independent predictor of IMT (β = 0.360, P < 0.001) in multivariable regression analyses. In a risk prediction model including variables of the UK Prospective Diabetes Study coronary heart disease risk engine urinary adiponectin, but not the albumin excretion rate, added significant value for the prediction of increased IMT (P = 0.007). CONCLUSIONS Quantification of urinary adiponectin excretion appears to be an independent indicator of vascular damage potentially identifying an increased risk for vascular events. PMID:19509019

    Although endometriosis is a common gynecologic pathologic phenomenon, involvement of the urinary tract is relatively rare. The clinical presentation and course of urinary system disease is extremely variable, as illustrated by the seven cases presented in this report. Therapy primarily is surgical, but a thorough understanding of the disease process and a complete knowledge of the patient's history and desires for fertility conservation are necessary to plot the most appropriate treatment course. Bladder involvement is more common, and usually less devastating, than either ureteral or kidney involvement. No signs, symptoms, or physical findings are pathognomonic, and the clinician must maintain a high index of suspicion in all cases of advanced pelvic endometriosis.

    1995-07-01

    Multiple sclerosis affects the lower urinary tract in many patients. The relationship between lower urinary tract abnormalities and disease-related parameters of multiple sclerosis is not well described. We screened urologically and neurologically 212 patients according to a standard protocol. Micturition complaints were noted in 52% of the patients and urodynamic abnormalities were found in 64%. A statistical correlation was found between detrusor hyperactivity and detrusor hypoactivity with disease-related parameters, that is disease duration, disability status, myelin basic protein concentration in the cerebrospinal fluid and neurophysiological investigations. No relationship was found between detrusor hypersensibility or detrusor hyposensibility and the aforementioned disease-related parameters. In 1 patient upper urinary tract abnormalities were noted in combination with urodynamic abnormalities. We conclude that lower urinary tract abnormalities can be found in every patient with multiple sclerosis unrelated to the state of the disease. Severe upper urinary tract abnormalities are rare.

    2008-04-01

    Urinary tract infections, most of which are biofilm infections in catheterized patients, account for more than 40% of hospital infections. Bacterial colonization of the urinary tract and catheters causes not only infection but also other complications such as catheter blockage by bacterial encrustation, urolithiasis and pyelonephritis. About 50% of long-term catheterized patients face urinary flow obstruction due to catheter encrustation, but no measure is currently available to prevent it. Encrustation has been known either to result from metabolic dysfunction or to be of microbial origin, with urease positive bacterial species implicated most often. Infectious calculi account for about 15-20% of all cases of urolithiasis and are often associated with biofilm colonization of a long-term indwelling urinary catheter or urethral stent. The use of closed catheter systems is helpful in reducing such problems; nevertheless, such a system only delays the inevitable, with infections emerging a little later. Various coatings intended to prevent the bacterial adhesion to the surface of catheters and implants and thus also the emergence of biofilm infections, unfortunately, do not inhibit the microbial adhesion completely and permanently and the only reliable method for biofilm eradication remains the removal of the foreign body from the patient.

    2013-01-01

    Urinary tract infections (UTIs) are one of the most frequent clinical bacterial infections in women, accounting for nearly 25% of all infections. Around 50–60% of women will develop UTIs in their lifetimes. Escherichia coli is the organism that causes UTIs in most patients. Recurrent UTIs (RUTI) are mainly caused by reinfection by the same pathogen. Having frequent sexual intercourse is one of the greatest risk factors for RUTIs. In a subgroup of individuals with coexisting morbid conditions, complicated RUTIs can lead to upper tract infections or urosepsis. Although the initial treatment is antimicrobial therapy, use of different prophylactic regimens and alternative strategies are available to reduce exposure to antibiotics. PMID:23984019

    We report a case of Inflammatory Abdominal Aortic Aneurysm (IAAA) producing bilateral hydro-ureteronephrosis. A 74-year-old patient presented to urologist office for bilateral hydronephrosis detected by kidney and bladder ultrasound (US). Patient reported lower urinary tract symptoms and inconstant and slight low back pain irradiated to inguinal region dating 3 weeks. Renal function, urine analysis and abdominal examination were normal. However the repeated ultrasound in the urologist office revealed abdominal aortic aneurism extended to iliac vessels. The patient was sent directly to vascular surgery unit where contrast computerized tomography (CT) and successful surgical repair were done. Final diagnosis was IAAA. The post-operative course was uneventful. Renal function was regular and the hydronephrosis reduced spontaneously under monitoring by CT and US. We review diagnosis and management of hydronephrosis that is sometimes linked to IAAA rather than standard AAA. Abdominal ultrasound is mandatory in any bilateral hydronephrosis and it could save lives. PMID:25641477

    The possible association of urinary tract infection (UTI) with ritual circumcision on the eighth day of life was studied by analyzing the epidemiology of urinary tract infections during the first year of life in 169 children with UTI (56 males and 113 females) born in Israel from 1979 to 1984. Forty-eight percent of the episodes of UTI occurring in males appeared during the 12 days following circumcision, and the increased incidence during that period was highly significant. The median age of the males at the time of the UTI was 16 days, compared with seven months in females. Ritual Jewish circumcision as practiced in Israel may be a predisposing factor for UTI during the 12-day period following that procedure.

    Recently, occurrence of urinary tract endometriosis (UTE) is more frequently diagnosed. According to literature, it refers to approximately 0.3 to even 12% of all women with endometriosis. The pathogenesis of UTE has not been clearly explained so far. The actually proposed hypotheses include embryonic, migration, transplantation, and iatrogenic theory. Most frequently UTE affects bladder, less often ureters and kidneys. One-third of patients remains asymptomatic or exhibits only minor manifestations. In symptomatic patients main complaints include dysuria, urinary urgency, and/or frequency, painful micturition, and burning sensation in the urethra and discomfort in the retropubic area. Treatment of UTE is challenging and can be pharmacological, surgical or can be a combination of both methods. In this paper we present a review of the literature concerning the UTE, its diagnosis and treatment. PMID:26341760

    Studies of manual wheelchair propulsion often assume bilateral symmetry to simplify data collection, processing, and analysis. However, the validity of this assumption is unclear. Most investigations of wheelchair propulsion symmetry have been limited by a relatively small sample size and a focus on a single propulsion condition (e.g., level propulsion at self-selected speed). The purpose of this study was to evaluate bilateral symmetry during manual wheelchair propulsion in a large group of subjects across different propulsion conditions. Three-dimensional kinematics and handrim kinetics along with spatiotemporal variables were collected and processed from 80 subjects with paraplegia while propelling their wheelchairs on a stationary ergometer during three different conditions: level propulsion at their self-selected speed (free), level propulsion at their fastest comfortable speed (fast), and propulsion on an 8% grade at their level, self-selected speed (graded). All kinematic variables had significant side-to-side differences, primarily in the graded condition. Push angle was the only spatiotemporal variable with a significant side-to-side difference, and only during the graded condition. No kinetic variables had significant side-to-side differences. The magnitudes of the kinematic differences were low, with only one difference exceeding 5°. With differences of such small magnitude, the bilateral symmetry assumption appears to be reasonable during manual wheelchair propulsion in subjects without significant upper-extremity pain or impairment. However, larger asymmetries may exist in individuals with secondary injuries and pain in their upper extremity and different etiologies of their neurological impairment.

    We determined the site of urinary tract infection in 51 elderly, institutionalized women (mean age, 80.5 years) with asymptomatic bacteriuria by using the Fairley bladder washout technique. Thirty-four (67%) infections were localized in the kidney and 17 (33%) in the bladder. Women with renal infection were older than those with bladder infection (81.9 vs. 77.6 years of age; P = .04). The antibody-coated bacteria test had a sensitivity of 58%, specificity of 71%, positive predictive value of 82%, and negative predictive value of 43% for upper-urinary-tract infection. A quantitative urinary leukocyte count of greater than or equal to 20 leukocytes/mm3 had a positive predictive value of 80% and a negative predictive value of 88% for upper-urinary-tract infection. This study suggests that the majority of elderly, institutionalized women with asymptomatic bacteriuria have upper-urinary-tract infection. Both the antibody-coated bacteria test and the quantitative urinary leukocyte count may be useful as noninvasive tests for localization of urinary tract infection in this population.

    Infection urinary stones resulting from urease-producing bacteria are composed by struvite and/or carbonate apatite. Bacterial urease splits urea and promotes the formation of ammonia and carbon dioxide leading to urine alkalinization and formation of phosphate salts. Proteus species are urease-producers, whereas a limited number of strains of other Gram negative and positive species may produce urease. Ureaplasma urealyticum and Corynebacterium urealyticum are urease-producers that are not isolated by conventional urine cultures, but require specific tests for identification. Primary treatment requires surgical removal of stones as complete as possible. Extracorporeal and endoscopic treatments are usually preferred, while open surgery is actually limited to few selected cases. Residual stones or fragments should be treated by chemolysis via ureteral catheter or nephrostomy or administration of citrate salts in order to achieve a stone-free renal unit. Postoperatively, recurrent urinary tract infection should be treated with appropriate antibiotic treatment although long-term antibiotic prophylaxis can cause resistance. Urinary acidification has been proposed for the prophylaxis of infection stones, but long-term acidification is difficult to achieve in urine infected by urease-producing bacteria. Urease inhibitors lead to prevention and/or dissolution of stones and encrustations in patients with infection by urea-splitting bacteria, but their use is limited by their toxicity. The administration of citrate salts involves an increase of the value of nucleation pH (pHn), that is the pH value at which calcium and magnesium phosphate crystallization occurs, in a greater way than the corresponding increase in the urinary pH due to its alkalinizing effect and resulting in a reduction of the risk of struvite crystallization. In conclusion prevention of the recurrence of infection stones can be achieved by an integrated approach tailored on the single patient. Complete

    Urinary incontinence (UI) is now recognized as a prevalent, physically and emotionally disruptive, and costly health problem in the geriatric population. Because incontinence may be a manifestation of a subacute or reversible process within or outside of the lower urinary tract, and because effective treatment is available, it is important for primary care physicians to identify and appropriately assess incontinence in their geriatric patients. The initial evaluation of an incontinent geriatric patients. The initial evaluation of an incontinent geriatric patient includes a targeted history and physical examination, urinalysis, and simple tests of lower urinary tract function. Potentially reversible conditions that may be causing or contributing to the incontinence, such as delirium and urinary tract infection (UTI), should be identified and managed. Patients who may benefit from further testing, including urologic or gynecologic examination and/or complex urodynamic tests, should be identified and referred. Several therapeutic modalities can be used to treat geriatric UI. Behavioral therapies are noninvasive and effective, both in functional community-dwelling geriatric patients and in functionally impaired nursing home residents. Behavioral therapies include bladder training, pelvic muscle exercises, biofeedback, scheduled toileting, habit training, and prompted voiding. Pharmacologic therapy is often used in conjunction with behavioral therapy. For stress incontinence, alpha-adrenergic drugs are used and can be combined with topical or oral estrogen therapy in women. For urge incontinence, pharmacologic treatment involves drugs with anticholinergic and direct bladder muscle relaxant properties. Pharmacologic therapy for overflow incontinence is generally not effective on a long-term basis. Surgical treatment is indicated when a pathologic lesion such as a tumor is diagnosed, or when anatomic obstruction is believed to be the cause of the patient's symptoms

    The prevalence of urinary complications after various anorectal operations was studied in a group of 273 patients. The overall prevalence of urinary complications was 26.7%; most of these complications affected men between 41 and 50, mainly after hemorrhoidectomy. In 10.6% of patients, bladder catheterization was needed. These urinary complications result from nervous reflexes originating from the anus and determined by the operative trauma and/or rectal distinction. In the treatment of these urinary complications, the role of the muses is essential for reassuring the patients. Parasympathomimetic drugs are often efficient. Urinary catheterization must be delayed until the 18th hour. Fluid restriction may be useful to prevent urinary retention. PMID:14870531

    A middle aged African-American woman with a stable history of carnitine palmitoyl transferase II (CPT II) deficiency presented with myalgias for 1 week. Physical examination and laboratory findings were consistent with severe sepsis secondary to pyelonephritis leading to rhabdomyolysis. Subsequent CT of the abdomen revealed bilateral supernumerary kidneys with non-obstructive calculi within the supernumerary kidneys. Abnormal ureteral development of the supernumerary kidneys likely led to an increased risk for urinary tract infections (UTIs) and renal calculi resulting in pyelonephritis. The stress of this infection overwhelmed the muscle CPT II enzyme load, putting her in a state of rhabdomyolysis. In addition to fluids and antibiotics, she was provided a diet rich in carbohydrates and low in fats so as to limit long-chain fatty acid oxidation. Supernumerary nephrectomy was not considered during this admission. During follow-up, she developed obstructive ureteral calculi requiring placement of a right-sided ureteral stent. PMID:24692375

Early detection of pathologies such as tumors or urinary tract obstructions, sometimes even before their clinical manifestation, has improved their management and prognosis in many cases. This, added to its low cost and harmlessness, makes ultrasound ideal for early approaches and follow-up of a wide number of urinary system pathologies. In this article, the ultrasound characteristics of the main urinary system pathologies that can be diagnosed by this technique, are reviewed.

    Performance on a range of visual-processing tasks has been shown to improve when information is split bilaterally across the left and right visual hemifields rather than being restricted to a single visual hemifield. However, a recent study by Delvenne et al. found no such bilateral advantage for subitizing, which is our ability to rapidly and accurately enumerate small quantities of objects. This finding is particularly surprising, as it contradicts the prediction of FINgers of INSTantiation theory that subitizing should benefit from bilateral presentation. Our study investigated the issue by determining if there are any circumstances where a bilateral advantage for subitization occurs. Contrary to Delvenne et al., we found that subitizing could show bilateral advantages, but only when the display was backward-masked. We discuss these findings in relation to how the rate of encoding and the time available for this encoding may affect bilateral advantages in subitizing. A general model is proposed under which bilateral advantages could be explained.

    The bilateral filter is a nonlinear filter that does spatial averaging without smoothing edges; it has shown to be an effective image denoising technique. An important issue with the application of the bilateral filter is the selection of the filter parameters, which affect the results significantly. There are two main contributions of this paper. The first contribution is an empirical study of the optimal bilateral filter parameter selection in image denoising applications. The second contribution is an extension of the bilateral filter: multiresolution bilateral filter, where bilateral filtering is applied to the approximation (low-frequency) subbands of a signal decomposed using a wavelet filter bank. The multiresolution bilateral filter is combined with wavelet thresholding to form a new image denoising framework, which turns out to be very effective in eliminating noise in real noisy images. Experimental results with both simulated and real data are provided. PMID:19004705

    Background Sacral neuromodulation has become a well-established and widely accepted treatment for refractory non-neurogenic lower urinary tract dysfunction, but its value in patients with a neurological cause is unclear. Although there is evidence indicating that sacral neuromodulation may be effective and safe for treating neurogenic lower urinary tract dysfunction, the number of investigated patients is low and there is a lack of randomized controlled trials. Methods and design This study is a prospective, randomized, placebo-controlled, double-blind multicenter trial including 4 sacral neuromodulation referral centers in Switzerland. Patients with refractory neurogenic lower urinary tract dysfunction are enrolled. After minimally invasive bilateral tined lead placement into the sacral foramina S3 and/or S4, patients undergo prolonged sacral neuromodulation testing for 3–6 weeks. In case of successful (defined as improvement of at least 50% in key bladder diary variables (i.e. number of voids and/or number of leakages, post void residual) compared to baseline values) prolonged sacral neuromodulation testing, the neuromodulator is implanted in the upper buttock. After a 2 months post-implantation phase when the neuromodulator is turned ON to optimize the effectiveness of neuromodulation using sub-sensory threshold stimulation, the patients are randomized in a 1:1 allocation in sacral neuromodulation ON or OFF. At the end of the 2 months double-blind sacral neuromodulation phase, the patients have a neuro-urological re-evaluation, unblinding takes place, and the neuromodulator is turned ON in all patients. The primary outcome measure is success of sacral neuromodulation, secondary outcome measures are adverse events, urodynamic parameters, questionnaires, and costs of sacral neuromodulation. Discussion It is of utmost importance to know whether the minimally invasive and completely reversible sacral neuromodulation would be a valuable treatment option for

    Objective The aim of this study was to evaluate the results of bilateral sacrospinous fixation (SSF), which was performed with surgical mesh interposition and bilateral vaginal repair. Material and Methods Twenty-two patients underwent SSF between 2010 and 2012, and the results were evaluated retrospectively. The results at preoperative and postoperative 6th, 12th, and 18th months of the pelvic organ prolapse quantification system (POP-Q) and the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire-12 (PISQ-12) were compared using Friedman and Wilcoxon Signed Ranks tests. Values of p<0.05 and <0.01 were considered statistically significant. Results According to the POP-Q, significant healing was observed on all vaginal vault points (p=0.001), and no prolapse was observed until the 18-month follow-up stage. There were also prominent patients who felt satisfactory with respect to their sexual life according to PISQ-12 (p=0.001). Conclusion This technique appears to provide an adequate clinical resolution, and it may be the primary surgical option for women with pelvic organ prolapse. PMID:26097393

    The number of injuries that force golfers to quit is also increasing. In particular, the upper body injuries are concerns for amateur golfers. This study was conducted not only to investigate muscular balance, such as ipsilateral and bilateral ratios of the upper body, but to also evaluate the possible problems of muscular joints in amateur golfers. Male golfers (n=10) and a healthy control group (n=10) were recruited for the assessment of muscular function in the upper body, which was measured by an isokinetic dynamometer at 60°/sec. The tested parts were trunk, wrist, forearm, elbow, and shoulder joints. Mann–Whitney U-test was used to evaluate the significance of the differences between groups. The ipsilateral ratios of peak torque or work per repetition (WR) of trunk flexor and extensor in the golfers were not significantly different compared to those of the control group. These results were similar to the shoulder horizontal abductor and adductor. However, there were significant differences in the ipsilateral and bilateral ratios of the wrist, forearm, and elbow joints. Especially, the WR of the wrist flexor, forearm pronator, and elbow flexor on the left side of amateur golfers showed imbalances in bilateral ratios. Moreover, the WR of the wrist and elbow flexors on the left side of amateur golfers were lower than those of the wrist and elbow extensors. Therefore, amateur golfers should strive to prevent injuries of the wrist, forearm, and elbow joints and to reinforce the endurance on those parts of the left side. PMID:27162771

    Electroconvulsive therapy (ECT) is the most effective treatment for patients suffering from severe or treatment-resistant major depressive disorder (MDD). Unfortunately its underlying neurobiological mechanisms are still unclear. One line of evidence indicates that the seizures produced by ECT induce or stimulate neuroplasticity effects. Although these seizures also affect the cortex, the effect of ECT on cortical thickness is not investigated until now. We acquired structural magnetic resonance imaging data in 19 treatment-resistant MDD patients before and after a bilateral ECT course, and 16 healthy controls at 2 time points, and compared changes in cortical thickness between the groups. Our results reveal that ECT induces significant, bilateral increases in cortical thickness, including the temporal pole, inferior and middle temporal cortex and the insula. The pattern of increased cortical thickness was predominant in regions that are associated with seizure onset in ECT. Post hoc analyses showed that the increase in thickness of the insular cortex was larger in responders than in non-responders, which may point to a specific relationship of this region with treatment effects of ECT.

    Urinary incontinence (UI) is a widely prevalent problem that affects people of all ages and levels of physical health, both in healthcare settings and in the community. Contributing to the problem are that many practitioners remain uneducated about this condition, individuals are often too ashamed or embarrassed to seek professional help, and there are significant variations in diagnostic and treatment practices. Five types of UI are stress, urge, overflow, functional and manufactured incontinence. Stress, urge and overflow are caused by factors within the urinary tract and will be concentrated on in this article. To diagnose UI a three-part assessment should be conducted, including the patient history, physical examination, and urinalysis. A behavioral program should be designed which incorporates identification and education for both patient and clinician. Treatment options include pelvic floor exercises (Kegel), vaginal cones, bladder training (retraining), habit training (timed voiding), electrostimulation and biofeedback, clean intermittent catheterization, indwelling catheters, medications, collagen injections, surgery, and absorption products. Most patients can be helped dramatically or cured with the appropriate treatment.

    Depth maps are used in many applications, e.g. 3D television, stereo matching, segmentation, etc. Often, depth maps are available at a lower resolution compared to the corresponding image data. For these applications, depth maps must be upsampled to the image resolution. Recently, joint bilateral filters are proposed to upsample depth maps in a single step. In this solution, a high-resolution output depth is computed as a weighted average of surrounding low-resolution depth values, where the weight calculation depends on spatial distance function and intensity range function on the related image data. Compared to that, we present two novel ideas. Firstly, we apply anti-alias prefiltering on the high-resolution image to derive an image at the same low resolution as the input depth map. The upsample filter uses samples from both the high-resolution and the low-resolution images in the range term of the bilateral filter. Secondly, we propose to perform the upsampling in multiple stages, refining the resolution by a factor of 2×2 at each stage. We show experimental results on the consequences of the aliasing issue, and we apply our method to two use cases: a high quality ground-truth depth map and a real-time generated depth map of lower quality. For the first use case a relatively small filter footprint is applied; the second use case benefits from a substantially larger footprint. These experiments show that the dual image resolution range function alleviates the aliasing artifacts and therefore improves the temporal stability of the output depth map. On both use cases, we achieved comparable or better image quality with respect to upsampling with the joint bilateral filter in a single step. On the former use case, we feature a reduction of a factor of 5 in computational cost, whereas on the latter use case, the cost saving is a factor of 50.

    Our main objective is to report the feasibility of performing simultaneous robotic-assisted laparoscopic (RAL) heminephrectomy with contralateral ureteroureterostomy in children with bilateral duplicated systems. Three female children with bilateral congenital renal/ureteral anomalies underwent concurrent RAL simultaneous unilateral partial nephrectomy with ureterectomy and contralateral ureteroureterostomy with redundant ureterectomy using a four/five-port approach. Mean age at repair was 32.9 months (range 7-46 months) and mean weight was 13.7 kg (range 10.4-13.6 kg). The RAL heminephroureterectomy and contralateral ureteroureterostomy were performed via a four-port approach (five ports in one patient), and the patients were repositioned and draped when moving to the other side. Mean operative time was 446 min (range 356-503 min). Mean estimated blood loss was 23.3 cc (range 10-50 cc). Postoperative length of stay for two patients was 2 days and 1 day for one patient (mean = 1.7 days). Mean length of follow-up was 18.3 months (range 7-36 months). No significant intraoperative or postoperative complications occurred for any of the three patients. Two children had no hydronephrosis on postoperative imaging in follow-up, and one child had a small stable, residual pararenal fluid collection on the side of heminephrectomy. Two patients underwent postoperative ureteral stent removal under general anesthesia. In children with bilateral duplicated urinary tract with ureterocele, ectopic ureter, and/or vesicoureteral reflux, laparoscopic repair with robotic assistance can be accomplished safely in a single operative procedure with a short hospital stay.

    Congenital bilateral vocal cord paralysis (CBVCP) is a rare but potentially life-threatening condition and awareness of the condition is necessary to ensure early diagnosis and treatment. This case describes a 25-month-old boy suffering from CBVCP. The main symptoms at birth were inspiratory stridor combined with a normal voice and feeding problems. The difficulties in achieving the right diagnosis are demonstrated, and the treatment so far, including tracheotomy and a feeding tube, is outlined. The importance of fibre optic laryngoscopy in both diagnosis and control is stressed. PMID:19174021

    Independent bilateral primary bronchial carcinomas are not common. Since Beyreuther's description in 1924, 16 well-documented cases of independent primary bronchial carcinomas of different histology have been described. From 1965 to 1970, eight cases were seen at the London Chest Hospital. In order to make the diagnosis of a second primary bronchial carcinoma, each tumour should be malignant and neither should be a metastasis from the other. To meet this last criterion, the histopathological features of the two tumours must be different. Many cases have been described in the literature as double primary bronchial carcinomas where the second primary had the same histological features as the first. Images PMID:4327711

    The authors report a case of a 49-year-old woman presenting a Cushing's syndrome (January 1997). The Magnetic Resonance Image of the pituitary gland revealed a microadenoma without extension in the cavernous sinus and a partial empty sella. The computed tomography scan showed a discreet bilateral adrenal hyperplasia with a left nodule (23 mm in diameter) a second nodule was noted. These data suggested the eventuality of maconodular adrenocortical hyperplasia in long-standing Cushing's disease. We discuss the implications of this finding for diagnosis, treatment and follow-up.

  15. Bilateral internal thoracic artery grafting

    PubMed Central

    2013-01-01

    The effectiveness of the left internal mammary artery graft to the anterior descending coronary artery as a surgical strategy has been shown to improve the survival rate and decrease the risk of adverse cardiac events in patients undergoing coronary bypass surgery. These clinical benefits appear to be related to the superior short and long-term patency rates of the internal thoracic artery graft. Although the advantages of using of both internal thoracic arteries (ITA) for bypass grafting have taken longer to prove, recent results from multiple data sets now support these findings. The major advantage of bilateral ITA grafting appears to be improved survival rate, while the disadvantages of complex ITA grafting include the increased complexity of operation, and an increased risk of wound complications. While these short-term disadvantages have been mitigated in contemporary surgical practice, they have not eliminated. Bilateral ITA grafting should be considered the procedure of choice for patients undergoing coronary bypass surgery that have a predicted survival rate of longer than ten years. PMID:23977627

    A case report of a 44 year-old white man admitted to the surgical unit for a bilateral simultaneous pneumothorax is presented. The pneumothorax occurred on day one after a surgical operation for discal hernia; in the past the patient already presented a right spontaneous pneumothorax at 32 years of age and a left pneumothorax at 37 years of age, both treated with a pleural drainage. A thoracic drain was bilaterally positioned with a good result only in the right side. The persistence of the left pneumothorax induced the authors to perform a postero-lateral thoracotomy bullae excision and pleurectomy with a good postoperative course. After a few months a new right pneumothorax occurred and the patient was treated with a right postero-lateral thoracotomy, bullae resection and pleurectomy. On the basis of the case reported, the authors consider the different opportunities in the treatment of spontaneous pneumothorax in relation to the present knowledges and technologies. Surgical procedure is to be preferred in case of persistence of pneumothorax despite a pleural drain and in case of pneumothorax in high risk subjects. Even if thoracoscopy seems to give better results regarding postoperative pain, it is not always possible with such a method to perform a careful pleurectomy neither to obtain it in all cases (above all in secondary pneumothorax). Every case must then be carefully studied to choose the best treatment at present available. PMID:11353349

    PubMed Central

    2015-01-01

    The urinary tract exits to a body surface area that is densely populated by a wide range of microbes. Yet, under most normal circumstances, it is typically considered sterile, i.e., devoid of microbes, a stark contrast to the gastrointestinal and upper respiratory tracts where many commensal and pathogenic microbes call home. Not surprisingly, infection of the urinary tract over a healthy person’s lifetime is relatively infrequent, occurring once or twice or not at all for most people. For those who do experience an initial infection, the great majority (70% to 80%) thankfully do not go on to suffer from multiple episodes. This is a far cry from the upper respiratory tract infections, which can afflict an otherwise healthy individual countless times. The fact that urinary tract infections are hard to elicit in experimental animals except with inoculum 3–5 orders of magnitude greater than the colony counts that define an acute urinary infection in humans (105 cfu/ml), also speaks to the robustness of the urinary tract defense. How can the urinary tract be so effective in fending off harmful microbes despite its orifice in a close vicinity to that of the microbe-laden gastrointestinal tract? While a complete picture is still evolving, the general consensus is that the anatomical and physiological integrity of the urinary tract is of paramount importance in maintaining a healthy urinary tract. When this integrity is breached, however, the urinary tract can be at a heightened risk or even recurrent episodes of microbial infections. In fact, recurrent urinary tract infections are a significant cause of morbidity and time lost from work and a major challenge to manage clinically. Additionally, infections of the upper urinary tract often require hospitalization and prolonged antibiotic therapy. In this chapter, we provide an overview of the basic anatomy and physiology of the urinary tract with an emphasis on their specific roles in host defense. We also highlight the

    A 45-year-old man of bilateral occipital infarction with central homonymous hemianopia is reported. He was admitted to our hospital with complaints of visual loss and large central scotoma on both eyes. Pupillary light reaction and ocular fundi were normal. On admission, bilateral retrobulbar optic neuritis was suspected. However, congruous, irregular central scotomas with vertical step were observed in both eyes with Goldmann perimetry. X-ray computed tomography (CT) and magnetic resonance imaging (MRI) revealed the infarction in bilateral occipital tips. Bilateral central homonymous hemianopia is considered to be rare and a case in which occipital lobe lesions were detected with X-ray CT and MRI has not been reported. We stress that bilateral central scotomas with vertical step indicate bilateral occipital lesions.

    2013-06-01

    Bilateral movement rehabilitation is gaining popularity as an approach to improve the recovery not only of bimanual function but also of unilateral motor tasks. While the neural mechanisms mediating the transfer of bilateral training gains into unimanual contexts are not fully understood, converging evidence from behavioral, neurophysiological, and imaging studies suggests that bimanual movements are not simply the superposition of unimanual tasks undertaken with both (upper) limbs. Here we investigated the neural responses in both hemispheres to bilateral ballistic motor training and the extent to which performance improvements transferred to a unimanual task. Since aging influences interhemispheric interactions during movement production, both young (n = 9; mean age 19.4 yr; 6 women, 3 men) and older (n = 9; 66.3 yr; 7 women, 2 men) adults practiced a bilateral motor task requiring simultaneous "fast-as-possible" abductions of their left and right index fingers. Changes in bilateral and unilateral performance, and in corticospinal excitability and intracortical inhibition, were assessed. Strong transfer was observed between bimanual and unimanual contexts for both age groups. However, in contrast to previous reports of substantial bilateral cortical adaptations following unilateral training, increases in corticospinal excitability following bilateral training were not statistically reliable, and a release of intracortical inhibition was only observed for older adults. The results indicate that the neural mechanisms of motor learning for bilateral ballistic tasks differ from those that underlie unimanual ballistic performance improvement but that aging results in a greater overlap of the neural mechanisms mediating bilateral and unilateral ballistic motor performance.

    A prospective study was undertaken to assess the feasibility and safety of bilateral simultaneous percutaneous nephrolithotomy (BPNL) under single anesthesia. BPNL was attempted in 16 consecutive patients with upper tract urolithiasis suitable for percutaneous treatment bilaterally. Bilateral simultaneous PNL could be accomplished in 14 of 16 cases; the opposite side was abandoned in 2 due to technical reasons. The operating sides could be switched within a short period (15 min) by rotating the patient table by 180 degrees. The average total operating time and irrigation time was 83 and 43 min, respectively. A total of 29 tracts and 18 sessions were required for endourologic treatment of 28 units in 14 patients. There was no significant morbidity. Complete clearance was achieved in 11 of 14 patients; there was insignificant residue in 1, while 2 with major residue required adjunct JJ stenting and extra-corporeal shockwave lithotripsy. The average hospital stay was 5.4 days. After initial proficiency with endourology, preparedness for BPNL is advisable in all such cases.

    1997-09-01

    The concept of nosocomial urinary tract infection now corresponds to a precise definition. It is generally related to bladder catheterization, constitutes the most frequent form of nosocomial infection (30 to 50% of infections), and represents the third most frequent portal of entry of bacteraemia. The organism most frequently isolated is Escherichia coli; but the flora is changing and the ecological distribution is continually modified. Despite their usually benign nature, these nosocomial infections can nevertheless influence hospital mortality; they increase the hospital stay by an average of 2.5 days and their treatment represents a large share of the antibiotic budget. Prevention of these infections is therefore essential, with particular emphasis on simple and universally accessible measures: very precise indications for vesical catheterization, use of closed circuit drainage, maximal asepsis when handling catheters, after washing the hands.

    Several million women suffer from urinary incontinence in Germany. Stress and urge incontinence are especially clinically relevant. Training of the pelvic floor muscles (vaginal cones, electrical stimulation, biofeedback, and so forth) plays a central role in the conservative therapy of stress incontinence. The use of devices such as incontinence tampons and urethral pessaries is also common. A medication for the therapy of stress incontinence, which improves the closure of the urethral sphincter, has been on the market since 2004. In the operative area,the insertion of a tension-free vaginal tape (TVT) has gained acceptance in recent years. Anticholinergics are the primary medication used in the treatment of urge incontinence. Local estrogens, low frequency electrical stimulation, phytotherapeutics and the like have supportive effects.

    Background Inguinal hernia repair, laparoscopic or open, is one of the most frequently performed operations in general surgery. Postoperative urinary retention (POUR) can occur in 0.2–35% of patients after inguinal hernia repair. The primary objective of this study was to determine the incidence of POUR after inguinal hernia repair. As a secondary goal, we sought to determine if perioperative and patient factors predicted urinary retention. Methods This study is a retrospective review of patients who underwent inguinal hernia repair with synthetic mesh at the Medical College of Wisconsin from January 2007 to June 2012. Procedures were performed by four surgeons. Clinical information and perioperative outcomes were collected up to hospital discharge. Urinary retention was defined as need for urinary catheterization post-operatively. Results A total of 192 patients were included in the study (88 bilateral, 46%) and (104 unilateral, 54%). The majority of subjects (76%) underwent laparoscopic repair. The overall POUR rate was 13%, with 25 of 192 patients requiring a Foley catheter prior to discharge POUR was significantly associated with bilateral hernia repairs (p=0.04), BMI≥35kg/m2 (p=0.05) and longer operative times (p=0.03). Based on odds ratio estimates, for every 10-minute increase in operative time, an 11% increase in the odds of urinary retention is expected (OR 1.11, CI 1.004 – 1.223; p=0.04). For every 10-minute increase in operative time, an 11% increase in POUR is expected. Conclusions Bilateral hernia repairs, BMI ≥ 35kg/m2, and operative time are significant predictors of POUR. These factors are important to determine potential risk to patients and interventions such as strict fluid administration, use of catheters, and potential premedication. PMID:25612548

    213 patients with urinary schistosomiasis were investigated under field conditions in the Peoples Republic of Congo by quantitative parasitological examination, urine analysis and abdominal ultrasonography. The study group consisted mainly of children. Disease related pathological ultrasonographical findings were dependent on the intensity of infection. Sixty patients had bladder wall thickening and 55 patients had vesical polyps. Those with multiple vesical polyps were the only patients with urinary retention and they had a significantly higher proteinuria than those with a singular polyp. Obstructive uropathy of different degrees was encountered in 50 cases. Of these, 21 patients had moderate to severe urinary tract obstruction and in all cases except one also presented concomitant vesical abnormalities. Nine patients revealed bilateral obstructive uropathy. Lesions of the lower urinary tract were a predisposing factor in the development of urinary tract obstruction. Morbidity of study patients was considered to be substantial. A proteinuria of more than one gramme per litre in spontaneously voided midday urine indicated a high probability for the presence of urinary tract obstruction and was considered an urgent indication for antischistosomal treatment.

    Background Essential tremor (ET) is one of the most common hyperkinetic movement disorders. Previous research into the pathophysiology of ET suggested underlying cerebellar abnormalities. Objective In this study, we added electromyography as an index of tremor intensity to functional Magnetic Resonance Imaging (EMG-fMRI) to study a group of ET patients selected according to strict criteria to achieve maximal homogeneity. With this approach we expected to improve upon the localization of the bilateral cerebellar abnormalities found in earlier fMRI studies. Methods We included 21 propranolol sensitive patients, who were not using other tremor medication, with a definite diagnosis of ET defined by the Tremor Investigation Group. Simultaneous EMG-fMRI recordings were performed while patients were off tremor medication. Patients performed unilateral right hand and arm extension, inducing tremor, alternated with relaxation (rest). Twenty-one healthy, age- and sex-matched participants mimicked tremor during right arm extension. EMG power variability at the individual tremor frequency as a measure of tremor intensity variability was used as a regressor, mathematically independent of the block regressor, in the general linear model used for fMRI analysis, to find specific tremor-related activations. Results Block-related activations were found in the classical upper-limb motor network, both for ET patients and healthy participants in motor, premotor and supplementary motor areas. In ET patients, we found tremor-related activations bilaterally in the cerebellum: in left lobules V, VI, VIIb and IX and in right lobules V, VI, VIIIa and b, and in the brainstem. In healthy controls we found simulated tremor-related activations in right cerebellar lobule V. Conclusions Our results expand on previous findings of bilateral cerebellar involvement in ET. We have identified specific areas in the bilateral somatomotor regions of the cerebellum: lobules V, VI and VIII. PMID:26909321

    Studies of manual wheelchair propulsion often assume bilateral symmetry to simplify data collection, processing, and analysis. However, the validity of this assumption is unclear. Most investigations of wheelchair propulsion symmetry have been limited by a relatively small sample size and a focus on a single propulsion condition (e.g., level propulsion at self-selected speed). The purpose of this study was to evaluate bilateral symmetry during manual wheelchair propulsion in a large group of subjects across different propulsion conditions. Three-dimensional kinematics and handrim kinetics along with spatiotemporal variables were collected and processed from 80 subjects with paraplegia while propelling their wheelchairs on a stationary ergometer during three different conditions: level propulsion at their self-selected speed (free), level propulsion at their fastest comfortable speed (fast), and propulsion on an 8% grade at their level, self-selected speed (graded). All kinematic variables had significant side-to-side differences, primarily in the graded condition. Push angle was the only spatiotemporal variable with a significant side-to-side difference, and only during the graded condition. No kinetic variables had significant side-to-side differences. The magnitudes of the kinematic differences were low, with only one difference exceeding 5°. With differences of such small magnitude, the bilateral symmetry assumption appears to be reasonable during manual wheelchair propulsion in subjects without significant upper-extremity pain or impairment. However, larger asymmetries may exist in individuals with secondary injuries and pain in their upper extremity and different etiologies of their neurological impairment. PMID:26125019

    The purposes of this study were to develop an experimental model of canine laryngeal paralysis that mimicked the naturally occurring disease and to document the upper airway changes produced, both clinically and with pulmonary function testing. Ten dogs had bilateral recurrent laryngeal neurectomy performed and were recovered from anesthesia. Tidal breathing flow-volume loop analysis and upper airway resistance measurements were taken before and after the development of clinical laryngeal paralysis while dogs breathed room air and after the individual administration of 2 respiratory stimulants. Clinical signs of laryngeal paralysis developed 38 days (median) following denervation. Although some variations were present, tidal breathing flow-volume loop analyses on room air, following denervation, were similar to those reported in naturally occurring cases. Upper airway resistance increased following denervation and was significantly increased with both respiratory stimulants. We concluded that bilateral recurrent laryngeal neurectomy resulted in clinical signs and respiratory changes similar to those of idiopathic canine laryngeal paralysis. PMID:9056067

    When a pregnant patient presents with a urinary calculus, the customary investigations and management must change in order to take into account the well-being of the developing fetus. Transabdominal or endovaginal ultrasound should be the initial imaging modality used in order to establish the diagnosis. A plain abdominal X-ray, limited intravenous pyelography, or retrograde pyelography is used secondarily if a definitive diagnosis is lacking. The treatment of first choice for urolithiasis in pregnancy is conservative, because 70-80% of stones will pass spontaneously. If conservative management fails, or in cases of sepsis, obstruction of a solitary kidney, or bilateral ureteric obstruction, then surgical intervention is indicated. Traditional surgical management consists of draining the obstructed collecting system with a ureteral stent or percutaneous nephrostomy tube with definitive treatment of the stone in the post-partum period. Ureteroscopic lithotripsy and stone extraction is another option that has been used safely and reliably with increasing frequency in many centers. Despite recent reports of using extracorporeal shock-wave lithotripsy, this treatment is still considered contraindicated in pregnancy.

    Bilateral adrenal hemorrhage with subsequent adrenal insufficiency is a recognized complication of anticoagulant therapy. Because the clinical manifestations are often nonspecific, the antemortem diagnosis of adrenal hemorrhage has been a difficult clinical problem. Computed tomography (CT) provides detailed images of the adrenal glands that are not possible with conventional imaging methods. The CT findings of bilateral adrenal hemorrhage in an anticoagulated patient are reported.

    Bilateral arm amputees usually are excellent foot users. To explore the plasticity of the primary motor cortex in upper-extremities amputees and to determine if the acquisition of special foot movement skill is related with the bilateral hand amputation, we studied the primary motor cortex by using combined task and resting state functional magnetic resonance imaging (fMRI). We investigated 6 bilateral arm amputees with or without special foot movement skill. In the task fMRI study, we found that toe tapping of all the amputees activated the bilateral hand area, including cases without special foot skill. In addition, cases without special foot skill mainly activated the precentral gyrus, which differed from those with more adept foot motor skill who activated both the precentral and postcentral gyri. To further understand the plasticity of the hand area, the resting state functional connectivity was investigated between the foot and hand regions. One-tailed two-sample t-test suggested that the connections between two areas became significantly stronger in the amputee group. Our study demonstrates that hand region of the cortex does not remain 'silent' after bilateral arm amputation, but rather is recruited by other modalities such as adjacent or nonadjacent cortexes to process motor information in a functionally relevant manner. From the data presented, it seems that the bilateral arm amputees have a strong potential to develop new skills in their remaining extremities and practice may further enhance this potential.

    Congenital bilateral diaphragm agenesis is a very rare condition. We describe limited (abdomen only) autopsy findings of a case of bilateral diaphragm agenesis in a 27-week male fetus with unusual findings of fibrosis of the pancreatic head and ectopic liver nodules in a mass at the upper abdomen that may represent a possible diaphragm anlage. We have correlated our observations with data from experimental and embryological studies to suggest possible mechanisms for the malformations that were present and their implications for our understanding of pancreas, liver and diaphragm development in the human fetus.

    A case of bilateral carpal tunnel syndrome and ulnar neuropathy at the elbow in a 22-year-old pizza chef is described. An on-site analysis revealed that job tasks performed by the worker exposed him to a combination of biomechanical risk factors. Patient history and workplace observations suggest that occupational physical exposure may have caused the bilateral entrapment neuropathies. The present report underlines the advisability of a detailed occupational history in the case of entrapment neuropathies of the upper limbs commonly regarded as being related to biomechanical occupational exposure.

    The incidence of stone disease has been increasing and the risk of recurrent stone formation is high in a pediatric population. It is crucial to use the most effective method with the primary goal of complete stone removal to prevent recurrence from residual fragments. While extracorporeal shock wave lithotripsy (ESWL) is still considered first line therapy in many clinics for urinary tract stones in children, endoscopic techniques are widely preferred due to miniaturization of instruments and evolution of surgical techniques. The standard procedures to treat urinary stone disease in children are the same as those used in an adult population. These include ESWL, ureterorenoscopy, percutaneous nephrolithotomy (standard PCNL or mini-perc), laparoscopic and open surgery. ESWL is currently the procedure of choice for treating most upper urinary tract calculi in a pediatric population. In recent years, endourological management of pediatric urinary stone disease is preferred in many centers with increasing experience in endourological techniques and decreasing sizes of surgical equipment. The management of pediatric stone disease has evolved with improvements in the technique and a decrease in the size of surgical instruments. Recently, endoscopic methods have been safely and effectively used in children with minor complications. In this review, we aim to summarize the recent management of urolithiasis in children.

    The first retroperitoneal lumbar sympathectomy was performed in 1924 by Julio Diez. The classic procedure for sympathectomy is open surgery. We report a unilateral laparoscopic retroperitoneal approach to perform bilateral lumbar sympathectomy. This approach was performed for a 43-year-old man with distal arterial occlusive disease and no indication for direct revascularization. His predominant symptoms were intermittent claudication at 100 metres and cold legs. The patient was placed in a left lateral decubitus position. The optical system was placed first in an intra-abdominal position to check that the trocars were well positioned in the retroperitoneal space. The dissection of retroperitoneum was performed by CO2 insufflation. The inferior vena cava was reclined and the right sympathetic chain was individualized. Two ganglia (L3-L4) were removed by bipolar electro-coagulation. The aorta was isolated on a vessel loop and careful anterior traction allowed a retro-aortic pre-vertebral approach between the lumbar vessels. The left sympathetic chain was dissected. Two ganglia (L3-L4) were removed by bipolar electro-coagulation. PMID:17685269

    There are three main highland areas on Venus: Beta Regio, Ishtar Terra and Aphrodite Terra. The latter is least known and the least mapped, yet existing analyses of Aphrodite Terra based on available Pioneer-Venus orbiter data suggest that it may be the site of extensive rifting. Some of the highest resolution (30 km) PV data (SAR) included most of the western half of Aphrodite Terra. Recent analysis of the SAR data together with Arecibo range-doppler topographic profiling (10 X 100 km horizontal and 10 m vertical resolution) across parts of Aphrodite, further characterized the nature of possible tectonic processes in the equatorial highlands. The existence of distinct topographic and radar morphologic linear discontinuities across the nearly east-west strike of Aphrodite Terra is indicated. Another prominent set of linear features is distinctly parallel to and orthogonal to the ground tracks of the PV spacecraft and are not included because of the possibility that they are artifacts. Study of the northwest trending cross-strike discontinuities (CSD's) and the nature of topographic and morphologic features along their strike suggest the presence of bilateral topographic and morphologic symmetry about the long axis of Aphrodite Terra.

    A nineteen years old woman with ambiguous external genitalia was studied. This condition had been previously identified as a newborn, but her parents refused medical attention and it was reared as a girl. At 12-years, she began spontaneous mammary development, appearing pubic and axillary hair, and clitoral enlargement. The menarche occurred at 15-years and it was followed by irregular periods. Physical examination, showed absence of hirsutism and acne, normal mammary development equivalent to grade V of Tanner. The external genitalia showed fused labio-scrotal folds with an small introitus. The urethral meatus was absent and was later located inside the introitus. There was a big phallus similar to an adult penis with a normal glans, flexed by a chordee. Hormonal determinations discarded congenital adrenal hyperplasia. The karyotype was 46,XX and testosterone levels were in adult male range. Pelvic ultrasonography disclosed a normal uterus and both gonads in confirmed by laparoscopy identifying bilateral ovotestis. Testicular tissue was removed and plastic reconstruction of female genitals was done. PMID:9528217

    Simultaneous bilateral inferior petrosal sinus sampling (BIPSS) plays a crucial role in the diagnostic work-up of Cushing's syndrome. It is the most accurate procedure in the differential diagnosis of hypercortisolism of pituitary or ectopic origin, as compared with clinical, biochemical and imaging analyses, with a sensitivity and specificity of 88-100% and 67-100%, respectively. In the setting of hypercortisolemia, ACTH levels obtained from venous drainage of the pituitary are expected to be higher than the levels of peripheral blood, thus suggesting pituitary ACTH excess as the cause of hypercortisolism. Direct stimulation of the pituitary corticotroph with corticotrophin-releasing hormone enhances the sensitivity of the procedure. The procedure must be undertaken in the presence of hypercortisolemia, which suppresses both the basal and stimulated secretory activity of normal corticotrophic cells: ACTH measured in the sinus is, therefore, the result of the secretory activity of the tumor tissue. The poor accuracy in lateralization of BIPSS (positive predictive value of 50-70%) makes interpetrosal ACTH gradient alone not sufficient for the localization of the tumor. An accurate exploration of the gland is recommended if a tumor is not found in the predicted area. Despite the fact that BIPSS is an invasive procedure, the occurrence of adverse events is extremely rare, particularly if it is performed by experienced operators in referral centres. PMID:27352844

    Among complications in orthognathic surgery, the insurgence of pneumothorax is very rare. Pneumothorax is the presence of air or gas in the pleural cavity and it is rare complications in the postoperative oral and maxillofacial surgery patient. The clinical results are dependent on the degree of collapse of the lung on the affected side. Pneumothorax can impair oxygenation and/or ventilation. If the pneumothorax is significant, it can cause a shift of the mediastinum and compromise haemodynamic stability. While 10% of pneumothoraces are asymptomatic, patients often complain of acute chest pain and difficulty breathing. There is a reduction in vital capacity, tachycardia, tachypnoea and a decrease in partial pressure of oxygen with an inability to maintain oxygen saturations. We observed this unusual surgical consequence in a 28-year-old female with negative clinical history and instrumental evaluation after Le Fort I osteotomy and bilateral sagittal split osteotomy (BSSO). No further consequences, no neurological sequelae, no infections and no other osteotomies sequelae were seen. Sudden post-surgical dispnea associated to sub-cutaneous emphysema of the neck and of the thorax must be adequately observed with the aim of monitoring further severe sequelae. The anaesthetic management of the emergency difficult airway in any post-surgical orthognatic treatment can be extremely difficult requiring a multi-disciplinary approach. PMID:23814593

    Ectopic pregnancy is identified with the widely-applied assisted reproductive technology (ART). Bilateral ectopic pregnancy is a rare form of ectopic pregnancy which is difficult to be diagnosed at the pre-operation stage. In this paper, we presented an unusual case of heterochronic bilateral ectopic pregnancy after stimulated intrauterine insemination (IUI), where there has been a delay of 22 d between the diagnoses of the two ectopic pregnancies. Literature was reviewed on the occurrence of bilateral ectopic pregnancy during the past four years in the MEDLINE database. We found 16 cases of bilateral ectopic pregnancy reported since 2008, and analyzed the characteristics of those cases of bilateral ectopic pregnancy. We emphasize that ovulation induction and other ARTs may increase the risk of bilateral ectopic pregnancy. Because of the difficulty in identification of bilateral ectopic pregnancy by ultrasonography, the clinician should be aware that the treatment of one ectopic pregnancy does not preclude the occurrence of a second ectopic pregnancy in the same patient and should pay attention to the intra-operation inspection of both side fallopian tubes in any ectopic pregnancy case.

    Primary adrenal myelolipoma is a rare, non-functioning adrenal benign tumor that is composed of mature adipose tissue and a variable amount of haemopoietic elements. Clinically, it is difficult to get diagnosed with adrenal myelolipoma because the patient usually doesn’t have obvious symptoms and signs in early stage. In the present study, two cases of primary bilateral adrenal myelolipomas are reported. Clinical presentation, imaging diagnostic features, histopathological changes and surgical treatments of the two patients are discussed. Preoperative diagnostic imaging examinations (B-mode ultrasonography, computed tomography and magnetic resonance imaging sans) assisted getting a prediction diagnosis of bilateral adrenal myelolipomas. A two-stage surgery was used to successfully excise bilateral adrenal myelolipomas in the two patients. Conventional open adrenalectomy was applied to remove the adrenal myelolipomas greater than 6 cm, and laparoscopic adrenalectomy was performed to excise the adrenal tumors smaller than 6 cm. Bilateral adrenal myelolipomas of the two patients were finally confirmed by postoperative histopathological examinations. Understanding clinical, imaging diagnostic and histopathological features of bilateral adrenal myelolipomas will facilitate timely diagnosis and treatment of this condition. Surgical removal of bilateral adrenal myelolipomas is safe, curative and beneficial. The two-stage surgery appears to be the best treatment option for the patients with bilateral adrenal myelolipomas because it achieves optimal treatment effectiveness with minimized sequelae.

A 26-year-old, 15-week pregnant woman presented with OD epiphora, diplopia, and pain in the setting of an inferomedial orbital mass. Surgical exploration and histopathology were consistent with a dacryocystocele, and a dacryocystorhinostomy was curative. She returned at 34-week gestation, with an identical presentation on the left side. Review of the literature reveals that dacryocystoceles occasionally present in adults; however, bilateral involvement may be unusual. Bilateral dacryocystoceles have not been previously reported in a pregnant woman.

    Fibromuscular dysplasia (FMD) describes a group of conditions which cause nonatheromatous arterial stenoses, most commonly of the renal and carotid arteries, typically in young women. We report a rare case of bilateral segmental renal infarction secondary to FMD in a young male patient. His initial presentation with loin pain and pyrexia resulted in a delay in the definitive diagnosis of FMD. He was successfully treated with bilateral balloon angioplasty. The delayed diagnosis in this patient until the condition had progressed to bilateral renal infarcts highlights the need for prompt investigation and diagnosis of suspected cases of FMD.

    Introduction Bilateral empyema is a rare and life-threatening condition that is difficult to treat. We herein report a case of bilateral empyema that was treated with simultaneous bilateral decortications via video-assisted thoracic surgery (VATS). Presentation of case A 38-year-old female complained of chest pain, dyspnea, and high grade fever lasting two weeks. Computed tomography revealed bilateral notching pleural effusion and pneumonia with atelectasis. Bilateral thoracic drainage was performed. From the right chest, white pus was drained, and Streptococcus anginosus was identified. The left drainage fluid was serous, and no bacteria were identified. We diagnosed the patient with right empyema and left para-pneumonic effusion consequent to pneumonia. Because conservative therapies could not resolve the inflammatory findings, simultaneous bilateral VATS decortications were performed. Both thoracic cavities had loculated pleural effusion. In contrast to the preoperative findings, white pus was found in not only the right, but also the left thoracic cavity. She had an uncomplicated postoperative course and recovered. Discussion Bilateral empyema that has developed to the fibrinopleural phase is difficult to treat with drains alone. Bilateral VATS decortications helped to make a definitive diagnosis and treat both sides simultaneously. Conclusion Simultaneous bilateral VATS decortications should be considered as a feasible and effective procedure for bilateral empyema that is refractory to medical treatment. PMID:25528031

    2012-01-01

    Oxidative damage produced by reactive oxygen species (ROS) has been implicated in the etiology and pathology of many health conditions, including a large number of chronic diseases. Urinary biomarkers of oxidative status present a great opportunity to study redox balance in human populations. With urinary biomarkers, specimen collection is non-invasive and the organic/metal content is low, which minimizes the artifactual formation of oxidative damage to molecules in specimens. Also, urinary levels of the biomarkers present intergraded indices of redox balance over a longer period of time compared to blood levels. This review summarizes the criteria for evaluation of biomarkers applicable to epidemiological studies and evaluation of several classes of biomarkers that are formed non-enzymatically: oxidative damage to lipids, proteins, DNA, and allantoin, an oxidative product of uric acid. The review considers formation, metabolism, and exertion of each biomarker, available data on validation in animal and clinical models of oxidative stress, analytical approaches, and their intra- and inter-individual variation. The recommended biomarkers for monitoring oxidative status over time are F2-isoprostanes and 8-oxodG. For inter-individual comparisons, F2-isoprostanes are recommended, whereas urinary 8-oxodG levels may be confounded by differences in the DNA repair capacity. Promising urinary biomarkers include allantoin, acrolein-lysine, and dityrosine. PMID:22683781

    Abstract Urothelial bladder cancer is the fourth most prevalent male malignancy in the United States and also one of the ten most lethal. Superficial or non-muscle-invasive bladder cancer has a high rate of recurrence and can progress to muscle invasive disease. Conventional surveillance requires regular cystoscopy and is used often with urinary cytology. Unfortunately, the cystoscopy procedure is invasive for patients and costly for health care providers. Urinary biomarkers have the potential to improve bladder cancer diagnosis, the efficiency and also the cost-effectiveness of follow up. It may also be possible for urinary biomarkers to help prognosticate particularly for patients with high-grade bladder cancer who may want enhanced assessment of their risk of disease progression. In this review the important historical urinary biomarkers and the newly emerging biomarkers are discussed. As will be presented, although many of the tests have good performance characteristics, unfortunately no single test can fulfill all the roles currently provided by cystoscopy and cytology. It is likely that in the future, urinary biomarker testing will be used selectively in a personalized manner to try and improve prognostication or reduce the necessity for invasive cystoscopy in patients understanding the limits of the test.

    Infection stones make up approximately 15% of urinary stone diseases and are thus an important group. These stones are composed of struvite and/or carbonate apatite. The basic precondition for the formation of infection stones is a urease-positive urinary tract infection. Urease is necessary to split urea into ammonia and CO(2). As a result, ammonia ions can form and at the same time alkaline urine develops, both being preconditions for the formation of struvite and carbonate apatite crystals. When these crystals are deposited infection stones form. Pathogenetically, various risk factors play a role: urinary obstruction, neurogenic bladder, dRTA, and MSK. If these infections are not treated and the stones are not removed, the kidney will be damaged. Modern methods are available for stone removal, e.g., ESWL and/or instrumental urinary stone removal. Here, especially less invasive methods are preferable. Any treatment must be adjusted to the patient individually. Patients should be examined frequently for recurrent urinary tract infections and stone recurrences, and new infections must be resolutely treated. Good therapy and prophylaxis are possible with present-day treatment modalities. PMID:12574884

It is part of vasculitis and causes an autoimmune attack by an abnormal type of circulating antibody termed ANCAs against small blood vessels. Disease concerns both men and women with a peak age of presentation in the sixth and seven decades. Typically upper and lower respiratory tract and kidneys are involved. Otitis externa, otitis media, or mastoiditis rarely occurs in granulomatosis with polyangiitis. Deafness is the most dangerous aural complication. Histological examination of biopsy is often not specific. A case of GPA with bilateral otitis media, bilateral deafness, and bilateral facial palsy with fatal course is presented. PMID:27493820

    2003-01-01

    Urinary calculi may be induced by a number of medications used to treat a variety of conditions. These medications may lead to metabolic abnormalities that facilitate the formation of stones. Drugs that induce metabolic calculi include loop diuretics; carbonic anhydrase inhibitors; and laxatives, when abused. Correcting the metabolic abnormality may eliminate or dramatically attenuate stone activity. Urinary calculi can also be induced by medications when the drugs crystallize and become the primary component of the stones. In this case, urinary supersaturation of the agent may promote formation of the calculi. Drugs that induce calculi via this process include magnesium trisilicate; ciprofloxacin; sulfa medications; triamterene; indinavir; and ephedrine, alone or in combination with guaifenesin. When this situation occurs, discontinuation of the medication is usually necessary. PMID:16985842

  4. Effective management of urinary discomfort.

    PubMed

    Hassay, K A

    1995-02-01

    Urinary discomfort is the second most common physical complaint affecting women. Although urinary discomfort is commonly a result of inflammation due to bacterial invasion, there are also nonbacterial causes. The development of antimicrobial resistance to bacteria is frequent and costs the patient and the medical community unnecessary time and money. Antimicrobial intervention should be instituted only after the uropathogen is identified through a urine culture. While awaiting the results of the urine culture or other laboratory or radiological tests, the patient's symptoms can be relieved with the use of urinary analgesics or antispasmodics. This conservative approach meets the immediate concern of the patient and better ensures a proper diagnostic workup and successful cure. Along with a conservative diagnostic approach, the patient should be included in all aspects of health care management.

    Abdominoscrotal hydrocele is a rare entity, with fewer than 100 cases reported in children. Bilateral abdominoscrotal hydroceles are even less common, with 14 cases reported in children. Various complications of abdominoscrotal hydrocele have been reported in the literature. We present a 4-month-old boy with bilateral giant abdominoscrotal hydroceles who developed appendicitis apparently because of obstruction from the right hydrocele. We discuss the various imaging modalities used to establish the diagnosis and plan the operative approach.

They point out the rarity of the bilateral kidney localization of hydatidosis, explain the dissemination mode, and stress the role of computed tomography for the pre-operative diagnosis. The treatment is above all surgical and adapted to each case. The post-operative results are satisfying. Complementary medical treatment could be useful. PMID:7486851

    Simultaneous, bilateral, and spontaneous rupture of the quadriceps tendon is a very rare injury. Individuals with this injury are usually predisposed by chronic renal disease with secondary hyperparathyroidism, gout, diabetes, and lupus erythematosus. Often, primary diagnostic confusion can lead to a delay in treatment. Two cases of a bilateral lesion of the quadriceps tendon, that were treated surgically using the technique of Scuderi, followed by an intense rehabilitation programme, are presented. Surgical treatment yields satisfactory results.

    Bladder cancer has the fifth highest incidence of all malignancies in the United States, with a propensity to recur, requiring lifelong surveillance after diagnosis. Urinary markers of disease have been of extreme interest in this field in an effort to simplify surveillance schedules and improve early detection of tumors. Many markers have been described, but most remain investigational. However, some markers have undergone clinical trials and are approved for clinical use. In this review, urinary markers and their application for screening and surveillance of bladder cancer are discussed. PMID:23864929

    Presentation of a review on nine patients (10 renal units) with urinary by-pass and renoureteral lithiasis who underwent shock wave extracorporeal lithotrity in our hospital. The justification for the by-pass was an infiltrant vesical tumour in 6 patients, myelomeningocele in 2, and vesicourethral trauma in the remaining one. All cases were being treated for a Bricker-type by-pass except the last one (bilateral ureterosigmoidostomy). Outcome of treatment was: absence of residual lithiasis in 6, minimal residues in 1 (2 renal units), failure in 1. The remaining patient suffered anaphylactic shock induced by the latex in the ureteral catheter placed prior to lithotrity which caused the patient's death.

    We aimed to investigate the role of urinary bladder shape which may potentially change with advancing age, increased waist circumference, pelvic ischemia, and loosening of the urachus on bladder emptying and UFR. We retrospectively investigated the medical records of 76 men. The patients were divided into two groups according to bladder shapes in MRI scan (cone and spheric shapes). There was a significant difference between the two groups in terms of IPSS, Qmax, Qave, and waist circumference. A positive correlation has been demonstrated between mean peak urinary flow rate measured with UFM and mean flow rate calculated using the CP. There was a significant difference between mean urinary flow rates calculated with CP of cone and sphere bladder shapes. The change in the bladder shape might be a possible factor for LUTS in men and LUTS may be improved if modifiable factors including increased waist circumference and loosening of the urachus are corrected.

    Summary A functional lesion in corticotrophin (ACTH)-independent Cushing’s syndrome is difficult to distinguish from lesions of bilateral adrenal masses. Methods for distinguishing these lesions include adrenal venous sampling and 131I-6β-iodomethyl-19-norcholesterol (131I-NP-59) scintigraphy. We present a case of a 29-year-old Han Chinese female patient with a history of hypercholesterolaemia and polycystic ovary syndrome. She presented with a 6month history of an 8kg body weight gain and gradual rounding of the face. Serial examinations revealed loss of circadian rhythm of cortisol, elevated urinary free-cortisol level and undetectable ACTH level (<5pg/mL). No suppression was observed in both the low- and high-dose dexamethasone suppression tests. Adrenal computed tomography revealed bilateral adrenal masses. Adrenal venous sampling was performed, and the right-to-left lateralisation ratio was 14.29. The finding from adrenal scintigraphy with NP-59 was consistent with right adrenal adenoma. The patient underwent laparoscopic right adrenalectomy, and the pathology report showed adrenocortical adenoma. Her postoperative cortisol level was 3.2μg/dL, and her Cushingoid appearance improved. In sum, both adrenal venous sampling and 131I-NP-59 scintigraphy are good diagnostic methods for Cushing’s syndrome presenting with bilateral adrenal masses. Learning points The clinical presentation of Cushing’ syndrome includes symptoms and signs of fat redistribution and protein-wasting features. The diagnosis of patients with ACTH-independent Cushing’s syndrome with bilateral adrenal masses is challenging for localisation of the lesion. Both adrenal venous sampling and 131I-NP-59 scintigraphy are good methods to use in these patients with Cushing’s syndrome presenting with bilateral adrenal masses. PMID:27252858

    Introduction The abducent nucleus is located in the upper part of the rhomboid fossa beneath the fourth ventricle in the caudal portion of the pons. The abducent nerve courses from its nucleus, to innervate the lateral rectus muscle. This nerve has the longest subarachnoid course of all the cranial nerves, it is the cranial nerve most vulnerable to trauma. It has been reported that 1% to 2.7% of all head injuries are followed by unilateral abducent palsy, but bilateral abducent nerve palsy is extremely rare. Case Presentation A 65-year-old woman presented to the emergency department following a motor vehicle accident. A neurological assessment showed the patient’s Glascow coma scale (GCS) to be 15. She complained of double vision, and we found lateral gaze palsy in both eyes. A hangman fracture type IIA (C2 fracture with posterior ligamentous C1 - C2 distraction) was found on the cervical CT scan. A three-month follow-up of the patient showed complete recovery of the abducent nerve. Conclusions Conservative treatment is usually recommended for traumatic bilateral abducent nerve palsy. Our patient recovered from this condition after three months without any remaining neurological deficit, a very rare outcome in a rare case. PMID:27218062

    Necrotizing fasciitis (NF) is a severe bacterial infection involving fascia and subcutaneous tissue. It generally affects upper or lower extremities unilaterally, and there are few reports of bilateral-extremity NF. Here, we report a case of a 43-year-old male with type 1 diabetes who had NF on the left foot and subsequently developed NF on the other foot 1 week later. The patient survived with antimicrobial therapy and bilateral below-knee amputation. As group B streptococcus (GBS) was isolated by blood culture and culture of excised tissues of both feet, bilateral GBS NF of the foot was diagnosed. GBS is a rare causative pathogen in NF; however, there have been two case reports of bilateral GBS NF of an extremity in which NF appeared on the opposite extremity 1 week after the primary site infection, as in our case. GBS was isolated from cultures of blood and excised tissues of both extremities in both cases. Together, these observations suggest that GBS has a potential to cause secondary NF at remote sites by hematogenous dissemination with approximately 1 week delay and thereby lead to bilateral NF.

He denied ocular pain, diplopia or change in the prominence of one or both eyes. Examination revealed 2 mm of relative proptosis on the right, bilateral temporal flare and lower lid retraction. There was minimal upper lid retraction and no evidence of lid lag. Ocular motility was full. Dilated fundoscopic examination revealed bilateral optic nerve edema, right more than left. CT of the orbit demonstrated enlargement of the extraocular muscles bilaterally with marked enlargement of the right medial rectus and left inferior rectus muscles resulting in crowding at the orbital apex bilaterally. Laboratory testing revealed the patient to be hyperthyroid. The patient was treated with high dose oral steroids followed by orbital radiation. Hyperthyroidism was managed by the patient's primary care physician. Visual symptoms rapidly improved with oral steroids and orbital radiation. Optic nerve edema completely resolved. Repeat CT imaging demonstrated a reduction in the enlargement of the extraocular muscles with relief of bilateral optic nerve compression.

    The treatment of renal and ureteral stones has undergone rapid and major changes over the past ten years. Extracorporeal shockwave lithotripsy has become the most commonly used modality for the treatment of renal and upper ureteral stones. Lower ureteral stones are more commonly being approached by retrograde techniques. Percutaneous nephrolithotomy, medical therapy, and open surgical nephrolithotomy offer viable alternatives in given situations. Presented here is the current application of each of these techniques, both alone and in combination, for the treatment of urinary stones.

    The aim of this study was to investigate the effect of furosemide on urinary acidification in 7 healthy children (aged 7 to 9 years) 5 patients with normokalemic distal renal tubular acidosis (RTA) (aged 4 to 13 years) and in 1 patient with proximal RTA (aged 20 months). Furosemide was given (2 mg/kg orally) as a tool to stimulate H+ and K+ secretion by enhancing Na delivery and transport in distal tubular segments. Patients with distal RTA were diagnosed by means of the ammonium chloride test and the alkaline overload and the one with proximal RTA by the ammonium chloride test only. Urinary acidification was evaluated 1 hour before and until 4 hours after furosemide administration. Healthy children (Fig. 1) showed a significant fall in urinary pH, 5.8 +/- 0.27 to 4.88 +/- 0.18 (p less than 0.02) and increase of NH3 excretion from 38.58 +/- 10.33 to 79.09 +/- 10.38 microEq/min/1.73 m2 (p less than 0.05). There was a direct correlation between urinary pH and urinary flow: r = 0.62 p less than 0.01 (Fig. 3). In patients with distal RTA (Fig. 5) furosemide failed to lower urine pH below 6 and net acid excretion persisted low: 47.9 +/- 6.1 microEq/min/1.73 m2. In the patient with proximal RTA (Fig. 4) furosemide produced the same effect as in healthy children with a fall in urine pH to 4.4 and an increase in net acid excretion to 118 microEq/min/1.73 m2. Furosemide proved to be effective to differentiate the type of RTA.(ABSTRACT TRUNCATED AT 250 WORDS)

    OBJECTIVES: This study determined the prevalence of urinary symptoms and their relationship to characteristics of a cohort of men in Beaver Dam, Wis, from 1993 to 1995. METHODS: A standardized questionnaire concerning urinary symptoms (the American Urological Association Urinary Symptom Questionnaire) was administered. RESULTS: All outcomes were associated with age and history of enlarged prostate. Urinary frequency (57%) and nocturia (65%) were the most common individual symptoms. Diuretic usage, diabetes, history of cardiovascular disease, and smoking were related to specific symptoms. CONCLUSIONS: While urinary symptoms are associated with age and history of enlarged prostate, symptoms may also be attributable to other diseases and exposures. PMID:10553401

    Choroidal osteoma is a an extremely rare (especially located bilaterally), benign, intraocular tumor, the type of choristoma. It occurs between 2-3 decades of life, women are particularly vulnerable. The main complication in 1/3 cases is a subretinal neovascularization which may cause bleeding. The gradually progressive decalcification develops within the tumour over time, which causes atrophy of the retinal pigment epithelium and Bruch's membrane deformity. The article presents a case of a 26-year-old woman with bilateral choroidal osteoma complicated by subretinal hemorrhage; the diagnosis was based on clinical examination (biomicroscopy and indirect ophthalmoscopy) as well as specialised tests including: ultrasonography, optical coherence tomography, and fluorescein angiography.

    Among the rare cardiac tumors, myxoma, which is mostly located in the left atrium, is the most common type. Bilateral atrial myxoma is extremely rare, and requires urgent surgery. The authors report the case of a 34-year-old male, who presented with one month of right hemiparesis and aphasia and subsequently diagnosed with bilateral atrial myxoma based on transthoracic echocardiography. An urgent operation for intra-cardiac tumor removal was performed with the biatrial approach. Once a diagnosis of myxoma has been made, an urgent operation for tumor removal is necessary due to the risk of serious complications, including sudden death from normal blood flow obstruction.

    The comprehension effects of changes in the spatial configuration of prose were examined with reading disabled children who differed in laterality preference. Specifically, 24 learning disabled boys were presented with prose materials in a standard, phrased, and backward (right to left) fashion. Measures of comprehension showed that text in the phrased and backward conditions differentially facilitated comprehension for the more bilateral subjects but had little effect on more right lateralized subjects. The results were discussed in terms of the instructional implications of alterations in the visual-spatial arrangement of prose materials for bilateral readers.

  19. Congenital urinary tract obstruction: the long view.

    PubMed

    Chevalier, Robert L

    2015-07-01

    Maldevelopment of the collecting system resulting in urinary tract obstruction (UTO) is the leading identifiable cause of CKD in children. Specific etiologies are unknown; most cases are suspected by discovering hydronephrosis on prenatal ultrasonography. Congenital UTO can reduce nephron number and cause bladder dysfunction, which contribute to ongoing injury. Severe UTO can impair kidney growth in utero, and animal models of unilateral ureteral obstruction show that ischemia and oxidative stress cause proximal tubular cell death, with later development of interstitial fibrosis. Congenital obstructive nephropathy, therefore, results from combined developmental and obstructive kidney injury. Because of inadequacy of available biomarkers, criteria for surgical correction of upper tract obstruction are poorly established. Lower tract obstruction requires fetal or immediate postnatal intervention, and the rate of progression of CKD is highly variable. New biomarkers based on proteomics and determination of glomerular number by magnetic resonance imaging should improve future care. Angiotensin inhibitors have not been effective in slowing progression, although avoidance of nephrotoxins and timely treatment of hypertension are important. Because congenital UTO begins in fetal life, smooth transfer of care from perinatologist to pediatric and adult urology and nephrology teams should optimize quality of life and ultimate outcomes for these patients.

    1975-01-01

    Human urinary protein was found to contain enzymes that hydrolyze leucyl-, alanyl-, and glycyl-prolyl-beta-naphthylamides. The kinetic constants of these enzymes were determined and their chemical properties studied. The pH optima for the hydrolysis of the various naphthylamides were also determined. Glycyl-prolyl-arylaminade was inhibited by Co(2+) and Mn(2+), while two other arylamidases were slightly activated by Co(2+). p-Chloromercuriphenyl-sulfonate and puromycin significantly inhibited leucyl and alanyl arylamidases. The mean values for 24-hour urinary output for leucyl-, alanyl-, and glycyl-prolyl arylamidases in normal human male subjects were 4.32, 9.97, and 2.2 units, respectively.

  1. MODERN USE OF URINARY ANTISEPTICS

    1952-01-01

    It is not necessary to resort to complete study in most cases of urinary tract infection. However, if the lesion is chronic or recurrent, associated with mixed organisms, complicated by lower tract involvement, accompanied by low total renal function, with or without abnormalities in a kidney-ureter-bladder x-ray film or in an intravenous urogram, then complete retrograde study should be carried out. A Gram stain will substitute for culture in most simple urinary tract infections and a trial of the agent of choice will act as a test of bacterial sensitivity. If the infection persists, however, more adequate bacteriologic studies are required. For good chemotherapeutic practice, it is important to: (1) Withhold the drug until it has been determined that obstruction, stone or other such lesion is not present; (2) watch for side effects and toxicity; and (3) give the best drug in large enough dosage for an adequate period of time.

    The role of tissue engineering in the cystectomy population rests on the principle of sparing healthy intestinal tissue while replacing diseased bladder. Over the last 25 years advances in cell biology and material science have improved the quality and durability of bladder replacement in animals. The neo-urinary conduit ([NUC]-Tengion) employs autologous fat smooth muscle cells which are seeded onto synthetic, biodegradable scaffolds. This seeded construct is then implanted in the patient and purportedly regenerates native urinary tissue to serve as a passive channel connecting the ureters to the skin surface. Preclinical animal studies as well as the first phase I human trial implanting the NUC are reviewed. While the ultimate goal of creating a durable, effective, tissue-engineered conduit is still in its infancy, important technical and experimental strides have been made. PMID:25677229

    Simple cysts are rare in the urinary bladder and can pose a diagnostic dilemma to both the urologist and the histopathologist. No case study was found in the database of Elsevier Science Direct, Spring-Link, or PubMed. We present two cases of subserous cyst in the bladder and discuss the diagnosis and treatment of the condition. The cystic lesion at bladder dome was detected by radiologic examination and confirmed by cystoscopy. In case 1, transurethral resection was first performed which was followed by partial cystectomy; In case 2, the cyst was removed with the urachus using laparoscopic surgery. The patients recovered uneventfully and the histopathology showed cysts in subserous layer of urinary bladder. The bladder cyst should be distinguished from urachal tumor, and laparoscopic partial cystectomy is the preferred operative procedure.

    Introduction Urinary tract candidiasis is known as the most frequent nosocomial fungal infection worldwide. Candida albicans is the most common cause of nosocomial fungal urinary tract infections; however, a rapid change in the distribution of Candida species is undergoing. Simultaneously, the increase of urinary tract candidiasis has led to the appearance of antifungal resistant Candida species. In this review, we have an in depth look into Candida albicans uropathogenesis and distribution of the three most frequent Candida species contributing to urinary tract candidiasis in different countries around the world. Material and methods For writing this review, Google Scholar –a scholarly search engine– (http://scholar.google.com/) and PubMed database (http://www.ncbi.nlm.nih.gov/pubmed/) were used. The most recently published original articles and reviews of literature relating to the first three Candida species causing urinary tract infections in different countries and the pathogenicity of Candida albicans were selected and studied. Results Although some studies show rapid changes in the uropathogenesis of Candida species causing urinary tract infections in some countries, Candida albicans is still the most important cause of candidal urinary tract infections. Conclusions Despite the ranking of Candida albicans as the dominant species for urinary tract candidiasis, specific changes have occurred in some countries. At this time, it is important to continue the surveillance related to Candida species causing urinary tract infections to prevent, control and treat urinary tract candidiasis in future.

    Melanosis of the bladder is rare. Only 10 cases have been described in the literature. We present the case of an 80-year-old woman with neurogenic lower urinary tract dysfunction due to spinal paralysis. During the diagnostic work-up which included cystoscopy, black spots in the bladder wall were observed. Histopathological evaluation revealed a benign suburothelial melanosis. Thus, with cystoscopic suspicion of a malignancy (melanoma), a biopsy is mandatory and regular cystoscopic follow-up is recommended. PMID:26358438

Typically, patients present with symptoms related to catecholamine hypersecretion or mass effect, but these tumors can also be encountered incidentally on imaging studies obtained for a different purpose. It is important to recognize the key imaging features of this entity so that it may be suggested as a possible differential diagnosis in the setting of a newly identified bladder mass.

    2007-04-01

    Although acute urinary retention (AUR) is not commonly thought of as a life-threatening condition, its presentation in orbit can lead to a number of medical complications that could compromise a space mission. We report on a middle-aged astronaut who developed urinary retention during two spaceflights. On the first mission of note, the astronaut initially took standard doses of promethazine and scopolamine before launch, and developed AUR immediately after entering orbit. For the first 3 d, the astronaut underwent intermittent catheterizations with a single balloon-tipped catheter. Due to the lack of iodine solution on board and the need for the astronaut to complete certain duties without interruption, the catheter was left in place for a total of 4 d. Although the ability to void returned after day 7, a bout of AUR reemerged on day 10, 1 d before landing. On return to Earth, a cystometrogram was unremarkable. During the astronaut's next mission, AUR again recurred for the first 24 h of microgravity exposure, and the astronaut was subsequently able to void spontaneously while in space. This report details the presentation of this astronaut, the precautions that were taken for space travel subsequent to the initial episode of AUR, and the possible reasons why space travel can predispose astronauts to urinary retention while in orbit. The four major causes of AUR--obstructive, pharmacologic, psychogenic, and neurogenic-are discussed, with an emphasis on how these may have played a role in this case.

    Bartter syndrome encompasses a variety of inheritable renal tubular transport disorders characterized by hypokalemia and hypochloremic metabolic alkalosis. Bartter syndrome Type III is caused by genetic alterations in the chloride channel kidney B (CLCNKB) gene and often presents in the first 2 years of life, known as classic Bartter syndrome. However, in rare cases Bartter syndrome Type III has an antenatal presentation with polyhydramnios, premature delivery and severe dehydration in the first weeks of life. Associations between congenital anomalies of the kidney and urinary tract and Bartter syndrome are extremely rare. This case report presents a girl with Bartter syndrome Type III due to a homozygous CLCNKB mutation and bilateral congenital anomalies of the kidney and urinary tract. In addition, we describe the antenatal presentation as well as its perinatal management.

    To report a rare case of a 19 year old female presenting with bilateral dacryocele and punctal and canalicular agenesis without epiphora. After clinical and radiological examination, the patient was found to have bilateral lacrimal gland agenesis as well. No other dental, otological or systemic abnormality suggestive of lacrimo-auricular-dento-digital syndrome was detected. She was managed with bilateral dacryocystectomy. Algorithm for managing such nonconventional lacrimal outflow dysgenesis based on presenting symptoms and co existing epiphora is proposed. Rationale of preferring lacrimal sac excision instead of dacryocystorhinostomy in this case is also discussed. PMID:24526864

    Indwelling double J ureteral stents are used for internal urinary diversion for ureteral obstruction and post-surgical drainage of the upper urinary tract. Stent calcification is a serious complication especially in those with forgotten stents. In a retrospective review of 16 patients (10 male and 6 female) we found holmium laser to be highly effective in the management of calcified stents. Encrustations/calcifications were noted on the distal end of the sent in 6 patiens (37.5%), middle and distal portions in 2 patients (12.5%), along the entire length of the stent in 3 patients (18.75%), lower portion of the stent in 4 patients (25%) and at the upper and lower ends of the stent in one patient (6.25%). Cystolitholapaxy, retrograde ureteroscopy (URS) with holmium: YAG (yttrium-aluminum-garnet) laser intracorporeal lithotripsy, percutaneous nephrostolithotomy (PNL) and antegrade URS with holmium: YAG laser intracorporeal lithotripsy were effectively performed without intraoperative complications. Lithotripsy became necessary before stent removal in 11 patients (68.75%). Holmium laser lithotripsy was useful in managing 7 patients (43.75%), and shockwave lithotripsy (SWL) in 6 patients (37.5%). In two patients (12.5%) both holmium and SWL were used before the stent can be removed.

  16. "Ostrich sign" indicates bilateral vertebral artery dissection.

    2012-11-01

    Vertebral artery dissections (VADs) comprise about 2% of ischemic strokes and can be associated with trauma, chiropractic manipulation, motor vehicle collisions, whiplash, amusement park rides, golfing, and other motion-induced injuries to the neck. We present a case of bilateral extracranial VAD as a complication of conducting an orchestra. To our knowledge, this has not been documented in the literature. Conceivably, vigorous neck twisting in an inexperienced, amateur conductor may place excessive rotational forces upon mobile portions of the verterbral arteries, tear the intima, deposit subintimal blood that extends longitudinally, and cause neck pain and/or posterior fossa ischemic symptoms. Magnetic resonance angiography examinations of axially oriented slices of bilateral VADs resemble the face of an ostrich. This observation is similar to the "puppy sign," in which bilateral internal carotid artery dissections resemble the face of a dog. Craniocervical dissections of either the carotid or vertebral arteries have the potential to form an aneurysm, cause artery-to-artery embolism, or completely occlude the parent artery, resulting in an ischemic stroke. Because bilateral VADs in axial magnetic resonance angiographic sections stand out like the eyes of an ostrich, and because the fast identification of VADs is so critical, we eponymize this image the "ostrich sign."

    Background Symptomatic bilateral internal carotid occlusive disease is a rare but potentially devastating entity. Medical therapy alone is associated with high rates of mortality and recurrent stroke. The optimal management of this disease remains poorly understood. Methods A retrospective review of a prospectively maintained database was conducted for patients who presented with an acute stroke in the setting of bilateral carotid occlusive disease between May and October 2013. Results We identified 3 patients. The admission National Institutes of Health Stroke Scale score ranged from 4 to 7. All patients had small- to moderate-sized infarcts in the anterior circulation on presentation. Angiography confirmed bilateral internal carotid occlusions with collateral filling via the posterior communicating artery and retrograde filling via external carotid artery supply to the ophthalmic artery. All patients were initially managed with permissive hypertension and anticoagulation followed by carotid angioplasty and stenting. At 1-year follow-up, all patients demonstrated a modified Rankin scale score of 0-1. Conclusions Carotid stenting may be a safe and effective therapy for patients presenting with symptomatic bilateral carotid occlusions. PMID:27051405

  20. Fast and Provably Accurate Bilateral Filtering.

    Chaudhury, Kunal N; Dabhade, Swapnil D

    2016-06-01

    The bilateral filter is a non-linear filter that uses a range filter along with a spatial filter to perform edge-preserving smoothing of images. A direct computation of the bilateral filter requires O(S) operations per pixel, where S is the size of the support of the spatial filter. In this paper, we present a fast and provably accurate algorithm for approximating the bilateral filter when the range kernel is Gaussian. In particular, for box and Gaussian spatial filters, the proposed algorithm can cut down the complexity to O(1) per pixel for any arbitrary S . The algorithm has a simple implementation involving N+1 spatial filterings, where N is the approximation order. We give a detailed analysis of the filtering accuracy that can be achieved by the proposed approximation in relation to the target bilateral filter. This allows us to estimate the order N required to obtain a given accuracy. We also present comprehensive numerical results to demonstrate that the proposed algorithm is competitive with the state-of-the-art methods in terms of speed and accuracy. PMID:27093722

    2014-06-01

    Subclavian steal syndrome (SSS) is usually caused by unilateral subclavian artery (SA) occlusion, and bilateral SSS is very rare. Takayasu's arteritis (TA) is a chronic granulomatous form of vasculitis that affects the SA, most commonly in women aged 15-40 years. We report a rare case of bilateral SSS due to TA in a 52-year-old woman, who exhibited severe vertigo. Although her blood pressure was within the normal range and did not differ between her arms, Doppler ultrasonography revealed low antegrade blood flow in the right SA and retrograde flow in the left SA. Computed tomography angiography demonstrated complete obstruction of the bilateral SA proximal to the vertebral artery origin. The more marked decrease in the blood flow of the vertebrobasilar artery experienced in bilateral SSS compared with unilateral SSS is considered to have caused the severe rotatory vertigo in the present patient. Since the vascular conditions of TA progressively deteriorate, delayed diagnosis and treatment could result in poor outcomes and unfavorable prognosis. We suggest that SSS with TA might require an early detection and treatment as well as careful follow-up for preventing vertigo and other neurological deficits in the vertebrobasilar arterial region.

    A 58-year-old man was referred to our hospital with high fever and anuria. Since undergoing a total pelvic exenteration due to bladder-invasive sigmoid colon cancer, urinary tract infections had frequently occurred. We treated with the construction of a bilateral percutaneous nephrostomy (PCN), and chemotherapy. Although we replaced the PCN with a single J ureteral catheter after an improvement of infection, urinary infection recurred because of an obstruction of the catheter. Urological examinations showed that an ileal conduit-ureteral reflux caused by kinking of the ileal loop was the reason why frequent pyelonephritis occurred. We decided to resect the proximal segment to improve conduit-ureteral reflux for the resistant pyelonephritis. After the surgery, the excretory urogram showed improvement and the urinary retention at the ileal conduit disappeared. Three years after the operation, renal function has been stable without episodes of pyelonephritis. Here we report a case of open repair surgery of an ileal conduit in a patient with severe urinary infection.

    Male urinary incontinence is an underestimated and frequently not broached issue. The urinary incontinence is divided into stress-, urge incontinence and hybrid forms as well as overflow incontinence. The fact that there are increasingly more men over 60 means that the prevalence of the urinary incontinence is up to 40%, and urinary incontinence will increasingly gain importance in daily routine practice. Many investigations and therapies can be realized by the general practitioner. Already simple therapy approaches can lead to a considerable clinical improvement of male urinary incontinence. If the initial therapy fails or pathological results (i. e. microhaematuria, recurrent urinary tract infections, raised residual urine and so on) are found, the patient should be referred to a urologist.

    A male tetraplegic patient attended accident and emergency with a blocked catheter; on removing the catheter, he passed bloody urine. After three unsuccessful attempts were made to insert a catheter by nursing staff, a junior doctor inserted a three-way Foley catheter with a 30-mL balloon but inflated the balloon with 10 mL of water to commence the bladder irrigation. The creatinine level was mostly 19 µmol/L (range: 0-135 µmol/L) but increased to 46 µmol/L on day 7. Computerized tomography urogram revealed that the bilateral hydronephrosis with hydroureter was extended down to urinary bladder, the bladder was distended, prostatic urethra was dilated and filled with urine, and although the balloon of Foley catheter was not seen in the bladder, the tip of the catheter was seen lying in the urethra. Following the re-catheterization, the creatinine level decreased to 21 µmol/L. A follow-up ultrasound scan revealed no evidence of hydronephrosis in both kidneys. Flexible cystoscopy revealed inflamed bladder mucosa, catheter reaction, and tiny stones. There was no bladder tumor. This case report concludes that the cause of bilateral hydronephrosis, hydroureter, and distended bladder was inadequate drainage of urinary bladder as the Foley balloon that was under-filled slipped into the urethra resulting in an obstruction to urine flow. Urethral catheterization in tetraplegic patients should be performed by senior, experienced staff in order to avoid trauma and incorrect positioning. Tetraplegic subjects with decreased muscle mass have low creatinine level. Increase in creatinine level (>1.5 times the basal level) indicates acute kidney injury, although peak creatinine level may still be within laboratory reference range. While scanning the urinary tract of spinal cord injury patients with indwelling urinary catheter, if Foley balloon is not seen within the bladder, urethra should be scanned to locate the Foley balloon.

    The goal of this study was to examine the relationship between the validity of postural movement and bilateral motor integration in terms of sensory integration theory. Participants in this study were 61 Chinese children ages 48 to 70 months. Structural equation modeling was applied to assess the relation between measures tapping postural movement and bilateral motor integration: for postural movement, the measures involve the Monkey Task, Side-Sit Co-contraction, Prone on Elbows, Wheelbarrow Walk, Airplane, and Scooter Board Co-contraction from the DeGangi-Berk Test of Sensory Integration, and Standing Balance with Eyes Closed/Opened in Southern California Sensory Integration Tests. For bilateral motor integration, the measures chosen were the Rolling Pin Activity, Jump and Turn, Diadokokinesis, Drumming, and Upper Extremity Control from the DeGangi-Berk Test of Sensory Integration, and Cross the Midline in Southern California Sensory Integration Tests (SCSIT). Postural movement was highly correlated with the bilateral motor integration. The factor structure fit the theoretical conceptualization, classifying postural movement and bilateral motor integration together in the same category. Therapists could combine two separate objectives (postural movement and bilateral motor integration) of intervention in an activity to improve the adaptive skills based on the vestibular-proprioceptive integration.

    Objective To investigate the mortality associated with cardiovascular diseases and the effect of estrogen treatment in women who underwent unilateral or bilateral oophorectomy before menopause. Design We conducted a cohort study with long-term follow-up of women in Olmsted County, MN, who underwent either unilateral or bilateral oophorectomy before the onset of menopause from 1950 through 1987. Each member of the oophorectomy cohort was matched by age to a referent woman from the same population who had not undergone any oophorectomy. We studied the mortality associated with cardiovascular disease in a total of 1,274 women with unilateral oophorectomy, 1,091 women with bilateral oophorectomy, and 2,383 referent women. Results Women who underwent unilateral oophorectomy experienced a reduced mortality associated with cardiovascular disease compared with referent women (hazard ratio [HR], 0.82; 95% confidence interval [CI], 0.67–0.99; P = 0.04). By contrast, women who underwent bilateral oophorectomy before age 45 years experienced an increased mortality associated with cardiovascular disease compared with referent women (HR, 1.44; 95% CI, 1.01–2.05; P = 0.04). Within this age stratum, the HR for mortality was significantly elevated in women who were not treated with estrogen through age 45 years or longer (HR, 1.84; 95% CI, 1.27–2.68; P = 0.001) but not in women treated (HR, 0.65; 95% CI, 0.30–1.41; P = 0.28; test of interaction, P = 0.01). Mortality was further increased after excluding deaths associated with cerebrovascular causes. Conclusions Bilateral oophorectomy performed before age 45 years is associated with increased cardiovascular mortality, especially with cardiac mortality. However, estrogen treatment may reduce this risk. PMID:19034050

    Lower urinary tract infections are very common diseases. Recurrent urinary tract infections remain challenging to treat because the main treatment option is long-term antibiotic prophylaxis; however, this poses a risk for the emergence of bacterial resistance. Some options to avoid this risk are available, including the use of cranberry products. This article reviews the key methods in using cranberries as a preventive measure for lower urinary tract infections, including in vitro studies and clinical trials.

    The artificial urinary sphincter (AUS), which has evolved over many years, has become a safe and reliable treatment for stress urinary incontinence and is currently the gold standard. After 4 decades of existence, there is substantial experience with the AUS. Today AUS is most commonly placed for postprostatectomy stress urinary incontinence. Only a small proportion of urologists routinely place AUS. In a survey in 2005, only 4% of urologists were considered high-volume AUS implanters, performing >20 per year. Globally, ~11,500 AUSs are placed annually. Over 400 articles have been published regarding the outcomes of AUS, with a wide variance in success rates ranging from 61% to 100%. Generally speaking, the AUS has good long-term outcomes, with social continence rates of ~79% and high patient satisfaction usually between 80% and 90%. Despite good outcomes, a substantial proportion of patients, generally ~25%, will require revision surgery, with the rate of revision increasing with time. Complications requiring revision include infection, urethral atrophy, erosion, and mechanical failure. Most infections are gram-positive skin flora. Urethral atrophy and erosion lie on a spectrum resulting from the same problem, constant urethral compression. However, these two complications are managed differently. Mechanical failure is usually a late complication occurring on average later than infection, atrophy, or erosions. Various techniques may be used during revisions, including cuff relocation, downsizing, transcorporal cuff placement, or tandem cuff placement. Patient satisfaction does not appear to be affected by the need for revision as long as continence is restored. Additionally, AUS following prior sling surgery has comparable outcomes to primary AUS placement. Several new inventions are on the horizon, although none have been approved for use in the US at this point. PMID:27445509

    2016-01-01

    INTRODUCTION: Spaceflight is associated with many factors which may promote kidney stone formation, urinary retention, and/or Urinary Tract Infection (UTI). According to ISS mission predictions supplied by NASA's Integrated Medical Model, kidney stone is the second and sepsis (urosepsis as primary driver) the third most likely reason for emergent medical evacuation from the International Space Station (ISS). METHODS: Inflight and postflight medical records of NASA astronauts were reviewed for urinary retention, UTI and kidney stones during Mercury, Gemini, Apollo, Mir, Shuttle, and ISS expeditions 1-38. RESULTS: NASA astronauts have had 7 cases of kidney stones in the 12 months after flight. Three of these cases occurred within 90 to 180 days after landing and one of the seven cases occurred in the first 90 days after flight. There have been a total of 16 cases (0.018 events per person-flights) of urinary retention during flight. The event rates per mission are nearly identical between Shuttle and ISS flights (0.019 vs 0.021 events per person-flights). In 12 of the 16 cases, astronauts had taken at least one space motion sickness medication. Upon further analysis, it was determined that the odds of developing urinary retention in spaceflight is 3 times higher among astronauts who took promethazine. The female to male odds ratio for inflight urinary retention is 11:14. An astronaut with urinary retention is 25 times more likely to have a UTI with a 17% infection rate per mission. There have been 9 reported UTIs during spaceflight. DISCUSSION: It is unclear if spaceflight carries an increased post-flight risk of kidney stones. Regarding urinary retention, the female to male odds ratio is higher during flight compared to the general population where older males comprise almost all cases due to prostatic hypertrophy. This female prevalence in spaceflight is even more concerning given the fact that there have been many more males in space than females. Terrestrial

  17. Metastatic transitional cell carcinoma of the urinary bladder presenting as a mandibular gingival swelling.

    2001-05-01

    Oral cavity metastases mostly originate from the breasts, lungs, or kidneys. Transitional cell carcinoma (TCC), the most frequent malignant tumor of the urinary bladder, rarely metastasizes to the jaws. To the best of our knowledge, only 8 cases of bladder carcinoma have been reported in the English literature to metastasize to the jawbones. A new case of mandibular metastasis of urinary bladder TCC with extension to the gingiva is presented in a 64-year-old white man. The patient was referred for a periodontal infection of the upper right first molar. The clinical examination also showed a gingival swelling located in the lower left premolar region with a hypoasthesia of the left side of the lower lip. The gingival mass was biopsied, and the microscopy showed a mandibular metastatic TCC of the urinary bladder extending to the gingiva. Periodontists should be aware that, although gingival metastases are rare, when they occur they may mimic other local benign pathological conditions. PMID:11394406

  18. Hardware Implementation of a Bilateral Subtraction Filter

    2009-01-01

    A bilateral subtraction filter has been implemented as a hardware module in the form of a field-programmable gate array (FPGA). In general, a bilateral subtraction filter is a key subsystem of a high-quality stereoscopic machine vision system that utilizes images that are large and/or dense. Bilateral subtraction filters have been implemented in software on general-purpose computers, but the processing speeds attainable in this way even on computers containing the fastest processors are insufficient for real-time applications. The present FPGA bilateral subtraction filter is intended to accelerate processing to real-time speed and to be a prototype of a link in a stereoscopic-machine- vision processing chain, now under development, that would process large and/or dense images in real time and would be implemented in an FPGA. In terms that are necessarily oversimplified for the sake of brevity, a bilateral subtraction filter is a smoothing, edge-preserving filter for suppressing low-frequency noise. The filter operation amounts to replacing the value for each pixel with a weighted average of the values of that pixel and the neighboring pixels in a predefined neighborhood or window (e.g., a 9 9 window). The filter weights depend partly on pixel values and partly on the window size. The present FPGA implementation of a bilateral subtraction filter utilizes a 9 9 window. This implementation was designed to take advantage of the ability to do many of the component computations in parallel pipelines to enable processing of image data at the rate at which they are generated. The filter can be considered to be divided into the following parts (see figure): a) An image pixel pipeline with a 9 9- pixel window generator, b) An array of processing elements; c) An adder tree; d) A smoothing-and-delaying unit; and e) A subtraction unit. After each 9 9 window is created, the affected pixel data are fed to the processing elements. Each processing element is fed the pixel value for

    Hypertrophic obstructive cardiomyopathy (HOCM) is a challenge to anesthesiologists due to the complex pathophysiology involved and various perioperative complications associated with it. We present a 50-year-old man, a known case of HOCM, who successfully underwent emergency haemostasis, and debridement of the traumatically amputated right upper limb and the contused lacerated wound on the left forearm under bilateral brachial plexus blocks. His co-morbidities included hypertension (in hypertensive crisis) and diabetes mellitus. He was full stomach and also had an anticipated difficult airway. The management included invasive pressure monitoring and labetalol infusion for emergent control of blood pressure. The regional anaesthesia technique required careful consideration to the dosage of local anaesthetics and staggered performance of brachial plexus blocks on each of the upper limbs to avoid local anaesthetic toxicity. Even though bilateral brachial plexus blocks are rarely indicated, it seemed to be the most appropriate anaesthetic technique in our patient. With careful consideration of the local anaesthetic toxicity and meticulous technique, bilateral brachial plexus blocks can be successfully performed in those patients where general anaesthesia is deemed to be associated with higher risk.

    The use of endoscopy in veterinary medicine has become the mainstay of diagnosis and treatment in the subspecialty of small animal urology over the past decade. This subspecialty is termed endourology. With the common incidence of urinary tract obstructions, stones disease, renal disease, and urothelial malignancies, combined with the recognized invasiveness and morbidity associated with traditional surgical techniques, the use of endoscopic-assisted alternatives using interventional endoscopic techniques has become appealing to both owners and clinicians. This article provides a brief overview of some of the most common urologic procedures being performed in veterinary medicine. PMID:26440205

    SUMMARY A prospective two year study of consecutive admissions (n=984) to a psychiatry ward revealed that the incidence of temporary urinary incontinence in psychiatric patients without delirium or dementia was 1.63% (n=l6). When compared with controls (n=64) the incontinent patients were more often psychotic, gave a history of childhood enuresis and a past history of temporary incontinence during psychosis. Compared with psychotic controls (n=26), incontinent patients (n=16) had been exposed to a greater variety of treatments and were hospitalized for longer periods. PMID:21743617

    In a colony of germfree rats 50 per cent of the males had urinary calculi composed of calcium citrate and calcium oxalate. Genetically closely related conventional animals on the same sterilized diet did not present a single case of stone formation. The tendency to calculus formation disappeared when germfree animals were contaminated with the intestinal flora from conventional rats. The calculus formation can readily be explained by the high calcium, high citrate, and high pH of the urine. This pattern was changed to that of conventional rats when the germfree rats were infected with intestinal microorganisms. PMID:13903130

    Introduction Isolated traumatic fractures of both Patellae, occurring at the same time, in an otherwise healthy person, are very rare. The Patella, as a subcutaneous and a cancellous bone, is vulnerable to injury. However, simultaneous injury to both Patellae without the involvement of any other bony injuries occurs infrequently, and only a few cases have been reported in the literature. Case Presentation We report a rare case of isolated, traumatic bilateral Patella fracture with unusual fracture patterns and briefly review the literature. Conclusions In simultaneous bilateral Patella fractures, good functional outcome can be expected following a stable surgical fixation and a structured rehabilitation regime. However, personality of the fracture determines salvage versus sacrifice of the Patella. PMID:27218047

    A high-level cognitive dichotomy ("language and context") is reviewed in relation to empirical findings concerning the functions of the human cerebral hemispheres. We argue that the right hemisphere's involvement in the generation of connotative and contextual information in parallel with the denotative and literal language functions of the left hemisphere provides an important insight into the organization of viable cognitive systems. The role of the corpus callosum in producing the dichotomy is discussed. Finally, the generation of asymmetrical activity in structurally symmetrical, bilateral neural nets is described. The model demonstrates how complementary memory states can be generated in bilateral nets without assuming different modes of information processing, provided that the nets have inhibitory, homotopic connections. Unlike excitatory connections, inhibitory connections are sufficient to generate asymmetric hemispheric activity without postulating intrinsic differences between the cerebral hemispheres.

    Although traumatic injury of the facial nerve is a relatively common condition in neurosurgical practice, bilateral lesions related to fracture of temporal bones are seldom seen. We report the case of a 38-year-old patient admitted to Intensive Care Unit after severe head trauma requiring ventilatory support (Glasgow Coma Scale of 7 on admission). A computed tomography (CT) scan confirmed a longitudinal fracture of the right temporal bone and a transversal fracture of the left. After successful weaning from respirator, bilateral facial paralysis was observed. The possible aetiologies for facial diplegia differ from those of unilateral injury. Due to the lack of facial asymmetry, it can be easily missed in critically ill patients, and both the high resolution CT scan and electromyographic studies can be helpful for correct diagnosis.

    Methods: 17 patients with Parkinson's disease were evaluated with a neuropsychological battery before and six months after bilateral pallidotomy. A comparison group (n = 8) was also assessed at six month intervals. Outcome variables were tests of memory, language, visuospatial function, attention, executive skills, and depression. Results: Despite a large number of variables studied, a significant postsurgical change was found only in performance of the tower of London task, a measure of planning abilities. The effect size of this change was larger than that of the comparison group, and a reliable change index score established that 5 of 13 surgical patients had statistically reliable reductions in planning performance. Conclusions: Patients with a young age of onset and long duration of Parkinson's disease who underwent bilateral pallidotomy had a relatively circumscribed reduction in neuropsychological functioning, being limited to motor planning efficiency. These data suggest that the cognitive role of the posteroventral globus pallidus is limited, at least in people with Parkinson's disease. PMID:12235317

The accurate diagnosis and presurgical planning was made by means of a computed tomography (CT) scan and a subsequent 3D reconstruction. After a primarily executed shielded repositioning of the bilateral hip dislocationearly secondary and anatomical reconstruction of the double-sided acetabulum fracture was possible using the Kocher-Langenbeck approach. A consistent physiotherapy as well as rehabilitation finally led to a positive clinical result for the patient.

    Inferior shoulder dislocation (luxactio erecta) is a rare lesion affecting approximately 0.5% of dislocations of this joint. The vast majority of these cases occur unilaterally. In September 2004, a 43 year old man was brought to the emergency room of the University Hospital of Santa Maria (HUSM) complaining of bilateral shoulder pain and inability to lower the arms, as a result of a fall with the arms abducted, while carrying out work activities. After physical examination and radiological exams, it was found that the patient had a bilateral inferior shoulder dislocation. He was referred to the surgical ward and after intravenous sedation, both shoulders were reduced by closed reduction using the traction-countertraction maneuver. The patient was discharged the day after the reduction. Both arms were immobilized with a velpeau sling in total adduction and intrarotation, with instructions to maintain immobilization for three weeks. The patient was also advised to receive physiotherapy. PMID:27047840

    We report a case of bilateral orbital hemorrhage as a complication of peribulbar anesthesia in a 78 year old man. Initially, unilateral orbital hemorrhage occurred but quickly spread to the contralateral side. Neuroophthalmological assessment revealed a proptosed tense globe with normal retinovascular findings. Visual acuity was adversely affected and this was conservatively managed with no lasting ophthalmic sequela. This patient’s case was reported as it illustrates an unusual complication of bilateral spread of orbital hemorrhage secondary to peribulbar anesthesia. It highlights how early ophthalmic assessment can ensure a good visual outcome in the setting of appropriate ophthalmic monitoring. The mechanisms of orbital hemorrhage spread and appropriate management options are discussed. PMID:27013899

    Legionnaires’ disease (LD) is an often overlooked but a possible cause of sporadic community acquired pneumonia. High fever, cough and gastrointestinal symptoms are non-specific symptoms. Hyponatremia is more common in LD than pneumonia linked with other causes. A definitive diagnosis is usually confirmed by culture, urinary antigen testing for Legionella species. Macolide or quinolone antibiotic is the treatment of choice. We describe a case of Legionella pneumonia presenting with high fever, bilateral flank pain and oliguria. It is important for clinicians to be aware of this diagnosis when managing patients with flank pain. The case highlights the problems in differentiating LD from renal colic and the importance of proper history, physical examination with laboratory tests for appropriate management. PMID:22154178

    2013-05-01

    We analysed the effects of task symmetry during bilateral accurate force production tasks performed by the two feet. In particular, we tested a hypothesis that bilateral deficit would lead to higher indices of synergies defined as co-varied adjustments in the two forces across trials that reduced total force variability. The subjects produced steady-state force followed by a quick force pulse into the target. The two feet could be acting both into plantar flexion and into dorsiflexion (symmetrical tasks), or in opposite directions (asymmetrical task). We used the framework of the uncontrolled manifold hypothesis to quantify two variance components, one of which did not change total force (V UCM), while the other did (V ORT). Synergy indices during the asymmetrical task were higher than in either symmetrical task. The difference was due to higher V UCM (compared to the symmetrical plantar flexion task) or lower V ORT (compared to the symmetrical dorsiflexion task). The synergy index showed a drop (anticipatory synergy adjustment, ASA) starting 100-150 ms prior to the force pulse initiation. The ASA tended to be shorter and of a smaller magnitude for the asymmetrical task. This is the first demonstration of bilateral synergies during accurate force production by the legs. We conclude that bilateral deficit has no or weak effects on two-leg synergies. The results fit the earlier introduced scheme with two groups of neural variables defining average performance of a redundant system and patterns of co-variation among its elemental variables, respectively.

    2015-01-01

    Patient: Male, 21 Final Diagnosis: Idiopathic bilateral external jugular vein thrombosis Symptoms: Face engorgement • neck swelling Medication: — Clinical Procedure: None Specialty: Hematology Objective: Unknown ethiology Background: Vein thrombosis is mainly determined by 3 factors, which constitute a triad called Virchow’s triad: hypercoagulability, stasis, and endothelial injury. Venous thrombosis commonly occurs in the lower extremities since most of the blood resides there and flows against gravity. The veins of the lower extremities are dependent on intact valves and fully functional leg muscles. However, in case of valvular incompetency or muscular weakness, thrombosis and blood stasis will occur as a result. In contrast, the veins of the neck, specially the jugulars, have distensible walls which allow flexibility during respiration. In addition, the blood directly flows downward towards the heart. Nevertheless, many case reports mentioned the thrombosis of internal jugular veins and external jugular veins with identified risk factors. Jugular vein thrombosis has previously been associated in the literature with a variety of medical conditions, including malignancy. Case Report: This report is of a case of idiopathic bilateral external jugular vein thrombosis in a 21 year-old male construction worker of Southeast Asian origin with no previous medical history who presented with bilateral facial puffiness of gradual onset over 1 month. Doppler ultrasound and computed tomography were used in the diagnosis. Further work-up showed no evidence of infection or neoplasia. The patient was eventually discharged on warfarin. The patient was assessed after 6 months and his symptoms had resolved completely. Conclusions: Bilateral idiopathic external jugular veins thrombosis is extremely rare and can be an indicator of early malignancy or hidden infection. While previous reports in the literature have associated jugular vein thrombosis with malignancy, the present

    Brodie's abscess is a form of subacute osteomyelitis, which typically involves the metaphyses of the long tubular bones, particularly in the tibia. The diagnosis is usually made incidentally, as there are no accompanying symptoms or laboratory studies. Bilateral involvement at the proximal tibia is unusual. However, orthopaedic surgeons should be aware of this entity, as it may present without symptoms. Checking the contralateral limb for concomitant Brodie's abscess is recommended.

    OBJECTIVE To report a two-stage protocol for children in whom bladder reconstruction was followed by kidney transplantation, as about a quarter of children requiring a kidney transplantation show significant lower urinary tract dysfunction, and consequently their bladder is unsuitable for a kidney transplant. PATIENTS AND METHODS Twelve children (median age 9.5 years, range 4.2-16.8) with end-stage renal disease had a lower urinary tract reconstruction before kidney transplantation. The cause of bladder dysfunction and renal failure included posterior urethral valves in five, neuropathic bladder in two, prune-belly syndrome in two, anal-rectum and urethral atresia syndrome in one, primary obstructive uropathy in one and caudal regression syndrome in one. Two children were diverted with an ileal conduit; four had a bladder augmentation, and four had a bladder augmentation with additional continent cutaneous stoma. A continent urinary reservoir was constructed in one boy, and one boy had a Mitrofanoff-only procedure. Subsequently, 11 children were transplanted. RESULTS The graft survival rate was 11 of 12 at 1 year and eight of 12 at 5 years. No patient lost the graft related to the reconstructed lower urinary tract. During the median (range) follow-up of 5.4 (1.6-12.5) years all but one child had free drainage of the upper urinary tract. All 10 children who did not have an ileal conduit are continent. CONCLUSION Reconstruction of the lower urinary tract followed by renal transplantation is a safe and efficient approach. It has the advantage of restoring the lower urinary tract before immunosuppressive therapy, and supplies the best possible reservoir for a transplanted kidney. PMID:19076129

    Granulomatosis with polyangiitis (GPA) formerly called Wegener’s granulomatosis is a chronic necrotizing granulomatous inflammatory disease with systemic vasculitis involving the upper and lower respiratory tract, and kidneys. The typical histopathology is that of necrotizing granulomatous inflammation with palisading histiocytes, neutrophils, and lymphocytes. We report a case of a 57-year-old lady presenting with left eye swelling, left ear pain and discharge, but with no pulmonary or renal symptoms.

    Granulomatosis with polyangiitis (GPA) formerly called Wegener's granulomatosis is a chronic necrotizing granulomatous inflammatory disease with systemic vasculitis involving the upper and lower respiratory tract, and kidneys. The typical histopathology is that of necrotizing granulomatous inflammation with palisading histiocytes, neutrophils, and lymphocytes. We report a case of a 57-year-old lady presenting with left eye swelling, left ear pain and discharge, but with no pulmonary or renal symptoms. Investigations revealed positive cytoplasmic antineutrophil cytoplasmic antibodies  and proteinase 3 antibodies. The CT and MRI showed meningeal thickening and bilateral structural changes of the orbits and mastoids. Lacrimal gland biopsy showed non necrotizing granulation with an eosinophilic infiltration. She was diagnosed with eosinophilic variant of GPA of the eyes and mastoid bones bilaterally extending to dura and sparing the lungs and kidneys. She responded to corticosteroids and rituximab.

    A supernumerary tooth is an additional entity to the normal series and can be seen in all quadrants of the jaw. Occurrence may be single or multiple, unilateral or bilateral, erupted or impacted in one or in both jaws. Multiple supernumeraries are rare in individuals with no other associated disease or syndromes. The conditions commonly associated with an increased prevalence of supernumerary teeth include cleft lip and palate, cleidocranial dysplasia and Gardner syndrome. The supplemental supernumerary refers to a duplication of teeth in normal series and is found at the end of a tooth series. A supplemental tooth may closely resemble the teeth of the group to which it belongs or it may bear little resemblance in size or shape to the teeth with which it is associated. This report presents a case with bilateral supplemental upper permanent lateral incisors without any symptoms of associated disorders. PMID:25168674

    A case of autism with CHARGE syndrome with microphthalmos and a superior colobomatous cyst arising from the optic disc is reported. A 7-year-old boy presented with a gradually increasing mass, involving the superior orbit and upper eyelid of right eye of 3 years' duration. Clinical examination revealed bilateral microphthalmos with typical iris coloboma, posterior synechiae, and cataractous lens. Imaging revealed bilateral optic disc colobomas with a superior cyst in the right orbit. Intraoperatively, a single cystic lesion was seen in the superior orbit arising from the optic disc region. Histopathology was suggestive of a colobomatous cyst, positive for glial tissue [glial fibrillary acidic protein (GFAP) positive] and neuroretinal elements (synaptophysin positive) on immunohistochemistry. Genetic analysis revealed a normal karyotype (46, XY).

    2012-04-01

    Urinary tract infections (UTI) in pregnant women are a relatively frequent occurrence and the spectrum of these infections ranges from lower urinary tract disease (asymptomatic bacteriuria, acute cystitis) to upper urinary tract disease (acute pyelonephritis). Anatomical and functional changes in the urinary tract in pregnancy result in significantly higher susceptibility to progression of the infection from asymptomatic bacteriuria to the stage of acute pyelonephritis. Untreated asymptomatic bacteriuria in pregnancy leads, in as much as 40%, to the development of acute pyelonephritis with all the subsequent negative effects not only for the woman herself, but particularly for the fetus. Bacteriuria in pregnancy accounts for a significantly higher number of newborns with a low birth weight, low gestational age and higher neonatal mortality rate. Therefore, it is necessary to perform screening for bacteriuria in pregnant women and, when the finding is positive, to treat this bacteriuria. The selection of an appropriate antimicrobial agent to treat urinary tract infection in pregnancy is limited by the safety of a given drug not only for the woman, but particularly for the fetus. The article provides an overview of medications that can be safely used throughout the pregnancy or only in certain stages of pregnancy. The selection of an appropriate antibiotic should always be preceded by the result of urine culture. The article presents the principles and rules for treating asymptomatic bacteriuria, acute cystitis and acute pyelonephritis in pregnant women. PMID:22702077

    Bilateral leg edema is a frequent symptom in older people and an important concern in geriatric medicine. Further evaluation is frequently not performed and simple therapy with diuretics is prescribed. Particularly in older patients, long-term use of diuretics can lead to severe electrolyte imbalances, volume depletion, and falls. In this case report we want to focus the physicians' attention on the necessity to determine the cause and show a correspondingly effective treatment for bilateral leg edema in older people. A thorough approach is required to recognize diseases and to avoid adverse drug events as geriatric patients often show an atypical presentation or minor symptoms. The cause of swollen legs is often multifactorial; therefore, the patient's individual history and an appropriate physical examination are important. Depending on the clinical symptoms, evaluation including basic laboratory tests, urinalysis, chest radiography, and echocardiogram may be indicated. The most probable cause of bilateral edema in older patients is chronic venous insufficiency. Heart failure is also a common cause. Other systemic causes such as renal disease or liver disease are much rarer. Antihypertensive and anti-inflammatory drugs can frequently cause leg edema, but the incidence of drug-induced leg swelling is unknown. With the help of this special case we tried to develop an approach to the diagnosis of symmetric leg edema in older patients, a problem frequently neglected in geriatric medicine.

  7. High Performance, Three-Dimensional Bilateral Filtering

    Image smoothing is a fundamental operation in computer vision and image processing. This work has two main thrusts: (1) implementation of a bilateral filter suitable for use in smoothing, or denoising, 3D volumetric data; (2) implementation of the 3D bilateral filter in three different parallelization models, along with parallel performance studies on two modern HPC architectures. Our bilateral filter formulation is based upon the work of Tomasi [11], but extended to 3D for use on volumetric data. Our three parallel implementations use POSIX threads, the Message Passing Interface (MPI), and Unified Parallel C (UPC), a Partitioned Global Address Space (PGAS) language. Our parallel performance studies, which were conducted on a Cray XT4 supercomputer and aquad-socket, quad-core Opteron workstation, show our algorithm to have near-perfect scalability up to 120 processors. Parallel algorithms, such as the one we present here, will have an increasingly important role for use in production visual analysis systems as the underlying computational platforms transition from single- to multi-core architectures in the future.

    We report here a case study of a rare neurological patient with bilateral brain damage encompassing a substantial portion of the so-called “limbic system.” The patient, Roger, has been studied in our laboratory for over 14 years and the current article presents his complete neuroanatomical and neuropsychological profiles. The brain damage occurred in 1980 following an episode of herpes simplex encephalitis. The amount of destroyed neural tissue is extensive and includes bilateral damage to core limbic and paralimbic regions, including the hippocampus, amygdala, parahippocampal gyrus, temporal poles, orbitofrontal cortex, basal forebrain, anterior cingulate cortex, and insular cortex. The right hemisphere is more extensively affected than the left, although the lesions are largely bilateral. Despite the magnitude of his brain damage, Roger has a normal IQ, average to above average attention, working memory, and executive functioning skills, and very good speech and language abilities. In fact, his only obvious presenting deficits are a dense global amnesia and a severe anosmia and ageusia. Roger's case presents a rare opportunity to advance our understanding of the critical functions underlying the human limbic system, and the neuropsychological and neuroanatomical data presented here provide a critical foundation for such investigations.

    The current international energy trade governance system is fragmented and multi-layered. Streamlining it for greater legal cohesiveness and international political and economic cooperation would promote global energy security. The current article explores three levels of energy trade governance: multilateral, regional and bilateral. Most energy-rich countries are part of the multilateral trading system, which is institutionalized by the World Trade Organization (WTO). The article analyzes the multilateral energy trade governance system by focusing on the WTO and energy transportation issues. Regionally, the article focuses on five major regional agreements and their energy-related aspects and examines the various causes that explain the proliferation of regional trade agreements, their compatibility with WTO law, and then provides several examples of regional energy trade governance throughout the world. When it comes to bilateral energy trade governance, this article only addresses the European Union’s (EU) bilateral energy trade relations. The article explores ways in which gaps could be filled and overlaps eliminated whilst remaining true to the high-level normative framework, concentrating on those measures that would enhance EU energy security.

    Acute spontaneous compartment syndrome of the forearm is rarely reported in the literature. It is typically associated with trauma or thromboembolism in the acute setting and repetitive exertional stress in the chronic setting. However it is rare for it to present bilaterally with no apparent underlying cause. We report the case of a young 31-year-old lady who presented to our Emergency Department with bilateral compartment syndrome of the forearm. Her presenting complaints included acute severe pain and swelling of the forearms bilaterally, with a decreased range of movement of the wrist and fingers. She also complained of numbness in all fingers. She had no history of recent trauma and ultrasound scans showed no evidence of vascular compromise. Past medical history was notable only for idiopathic hypertension and coeliac disease. The patient was taken to theatre urgently where flexor and extensor compartments and carpal tunnel were decompressed. Pronator Teres was found to be dusky initially but turned pink after decompression. All other muscles were normal. An interesting fact of this case was that combination of the high compartment pressures and anaesthetic related hypotension caused the forearm pulses to become impalpable at induction, these returned intra-operatively. The patient has been seen in the outpatient department following discharge. She is well apart from some mildly reduced grip strength in her right hand likely due to carpal tunnel decompression. No cause was found for the scenario after extensive medical investigation.

  15. Urinary glucose and vitamin C.

    Brandt, R; Guyer, K E; Banks, W L

    1977-11-01

    The recent popularization of self-prescribed large doses of vitamin C has increased the possibility for erroneous conclusions to be drawn from standard clinical methods used in urinary glucose monitoring, due to interference with these methods by the greatly elevated excretion of vitamin C. The coupled-enzyme-chromogen strip tests showed erroneously negative glucose levels in urines of both a diabetic individual and a subject with a genetic low renal threshold for glucose when they were supplementing their normal diets with 1-2 g vitamin C per day. With this regimen, their urinary vitamin C levels reached 200 mg/dl (11.4 mmol/l). For normal urine with vitamin C added, false-positive tests for glucose were found using Benedict's reagent when vitamin C was present at 250 mg/dl (14.3 mmol/l) or higher concentrations. In diabetic individuals consuming large quantities of vitamin C, this interference with standard coupled-enzyme-chromogen strip tests or Benedict's test could present a significant problem in diagnosis and clinical management of the disease. A simple anion exchange method of treating the urine was used to correct the false results. PMID:920657

  16. Achieving urinary continence in children.

    PubMed

    Wu, Hsi-Yang

    2010-07-01

    Achievement of urinary continence is an important developmental step that most children attain with the assistance of their parents and caregivers. Debate continues as to the best time to toilet train; in some Asian and African cultures children are trained as infants, while training at age 2-3 years is more typical in Western cultures. Infant voiding is not merely a spinal reflex, as the sensation of bladder filling is relayed to the brain. However, the ability of the brain to inhibit bladder contractions, and to achieve coordinated bladder contraction with sphincter relaxation, matures over time. While there is a concern that later toilet training may be responsible for an increase in urinary incontinence in children, no controlled studies on early versus late toilet training exist to evaluate this hypothesis. A number of medical conditions such as spina bifida, posterior urethral valves, cerebral palsy and autism can cause incontinence and difficulties in toilet training. The decision to start toilet training a child should take into account both the parents' expectation of how independent the child will be in terms of toileting, and the child's developmental readiness, so that a realistic time course for toilet training can be implemented.

    A urinary tract infection (UTI) is a collective term for infections that involve any part of the urinary tract. It is one of the most common infections in local primary care. The incidence of UTIs in adult males aged under 50 years is low, with adult women being 30 times more likely than men to develop a UTI. Appropriate classification of UTI into simple or complicated forms guides its management and the ORENUC classification can be used. Diagnosis of a UTI is based on a focused history, with appropriate investigations depending on individual risk factors. Simple uncomplicated cystitis responds very well to oral antibiotics, but complicated UTIs may require early imaging, and referral to the emergency department or hospitalisation to prevent urosepsis may be warranted. Escherichia coli remains the predominant uropathogen in acute community-acquired uncomplicated UTIs and amoxicillin-clavulanate is useful as a first-line antibiotic. Family physicians are capable of managing most UTIs if guided by appropriate history, investigations and appropriate antibiotics to achieve good outcomes and minimise antibiotic resistance.

    Isoelectric focusing of human urinary metallothionein at a pH range of 4.8 to 7.0 yielded a single protein band with a pI of 5.57 which co-migrated with authentic purified metallothionein I from human liver. Minimum pretreatment of the urine samples (160 ml) was needed. The preparatory steps included sample concentration with the original protein, enriched from 69 +/- 23 micrograms/ml to 2.0 +/- 1.4 mg/ml (+/- SD; n = 9), followed by heat treatment at 80 degrees C for 5 min (2.4 +/- 1.7 mg protein/ml). After focusing, the gels were stained with silver and the lanes were scanned with a laser scanner. Peak areas were used for quantitation with commercial beta 2-microglobulin as a standard. The urinary metallothionein ranged from 1.0 to 2.6 nmol/mmol creatinine, which is comparable with values reached by radio-immunoassay.

    1. Bilaterally adrenalectomized adult sheep, taken off replacement therapy, exhibit decreased plasma sodium, and increased plasma potassium, urinary sodium excretion and urinary sodium:potassium ratio. The hypothesis tested was that these effects would not be seen in adrenalectomized ovine fetuses, due to the mother being the major regulator of fetal fluid balance. 2. The fetuses of seven Merino ewes were bilaterally adrenalectomized at 120 +/- 0.3 days of gestation (term is 150 days) and a bladder cannula inserted. Urine flow and composition were measured six times between 125 and 142 days of gestation, and compared with results in seven control fetuses at the same gestational ages. At between 142 and 145 days of gestation, blood samples were taken from the ewe and fetus, they were killed and the volume and composition of amniotic and allantoic fluids measured. 3. Adrenalectomized fetuses had significantly lower (P < 0.05) plasma aldosterone concentration than that observed in intact fetuses (adrenalectomized, 92 +/- 16 pmol l-1; intact, 224 +/- 46 pmol l-1; P < 0.001). Plasma cortisol level was also lower (adrenalectomized, 8.6 +/- 1.4 nmol l-1; intact, 110.3 +/- 24.8 nmol l-1). Maternal plasma steroids were similar in both groups. 4. There were no significant differences in fetal urine flow rate, osmolality or composition until 139-142 days of gestation. At this time urine sodium:potassium ratio was significantly greater in adrenalectomized (P < 0.05) than intact fetuses. 5. There were no significant differences in maternal or fetal plasma solutes in the two groups and only minor alterations in the volume and composition of amniotic and allantoic fluid. The conclusion is that the major determinant of fetal fluid and electrolyte balance is placental transfer of water and electrolytes from the mother. PMID:8583407

    The aims of this study were to investigate the nature and extent of upper limb deformities via the use of various classifications, and to analyze the relationship between upper limb deformities and gross motor or upper limb functionality levels. Upper extremity data were collected from 234 children with spastic cerebral palsy (CP) who were admitted to the university hospital for intensive rehabilitation. Upper limb deformities were classified according to the Zancolli classification for finger and wrist extension ability, the Gshwind and Tonkin classification for supination ability, and the House classification for thumb-in-palm deformity. Digital deformity was also classified. Upper limb function was assessed using the Upper Extremity Rating Scale (UERS) and the Upper Limb Physician's Rating Scale (ULPRS). Gross motor function was assessed using the Gross Motor Functional Classification System (GMFCS). Among the 234 children observed, 70.5% had a limitation in forearm supination, and 62.8% had problems with wrist and finger extension in at least one limb. Thumb-in-palm deformity of at least one hand was found in 47.0% of patients. Swan neck deformity was the most common finger deformity. Upper limb functional measures, the ULPRS and the UERS, significantly correlated with the degree of upper limb deformity, as assessed by the Gschwind and Tonkin, Zancolli, and House classifications. Further, the degree of upper limb deformity was significantly related to the GMFCS level in children with bilateral CP, but not in children with unilateral CP. Limitation of forearm supination was the most common upper limb deformity in children with spastic CP. The degree of upper limb deformity significantly affected upper limb function in these children.

    Kidney transplant is the final treatment for patients with end-stage renal disease. Urinary leakage is the most-common surgical complication early after transplant. Another complication in the early posttransplant period is segmental allograft infarction. We report a kidney recipient who developed urinary leakage secondary to a segmental infarction of the upper pole of the transplanted kidney 2 months after transplant. The patient was treated successfully by a partial nephrectomy of the infracted upper lobe of the kidney. Three months after the partial nephrectomy of the allograft, serum blood urea nitrogen and creatinine were normal, and the patient was able to partake in her daily activities. Partial nephrectomy in the context of infarction of a kidney allograft is safe and can be used in similar cases.

    Spinal anesthetic is a common form of surgical anesthetic used in foot and ankle surgery. Spinal morphine anesthetic is less common, but has the advantage of providing postoperative analgesia for 12 to 24 hr. A number of complications can occur with spinal anesthesia, including urinary retention that may be a source of severe and often prolonged discomfort and pain for the patient. Management of this problem may require repeated bladder catheterization, which may lead to urinary tract infections or impairment of urethrovesicular function. This study reviews the incidence of urinary retention in 80 patients (40 after general anesthesia and 40 after spinal anesthesia) who underwent foot and ankle surgery at Saint Joseph's Hospital, Philadelphia, PA. Twenty-five percent of the patients who had spinal anesthesia experienced urinary retention, while only 7 1/2% of the group who had general anesthesia had this complication. Predisposing factors, treatment regimen, and recommendations for the prevention and management of urinary retention are presented.

    The first case of man who presented to psychiatry emergency room for evaluation of abnormal behavior because of urinary stones was reported. Careful evaluation of patient led to a diagnosis of 37 urinary bladder stones in an Egyptian man with obstructive uropathy and metabolic defects in the form of hyperoxaluria and hypocitraturia. Knowledge of the differential diagnosis of metabolic defects can lead to successful outcome in preventing reformation of urinary tract stones after surgery. A 61-year-old Egyptian man presented to psychiatry emergency room because he was found lying on floor in bathroom to urinate by his wife who thought her husband needed psychiatric evaluation. Patient gave history of frequent urination and dysuria on and off for 3 years. In the last 3 months before his presentation to emergency room, he got into a habit of lying down on his left side when he went to bathroom to urinate because it was easier for him to pass urine. Renal consultation requested because of presence of red blood cells in urinalysis. Computed tomography of the abdomen and pelvis showed bilateral hydronephrosis and multiple bladder stones. Twenty-four-hour urine collection showed low urinary citrate and high oxalate. Patient underwent open vesicolithotomy and removal of 36 stones. Stone analysis showed 75% uric acid and 25% calcium oxalate. Patient did very well after surgery, and 1 month later, he underwent transuretheral resection of prostate without any complications. Now patient has no difficulty passing urine and he has no recent attack of urinary tract infection. Knowledge of the differential diagnosis of metabolic defects in men with urinary bladder stones would hopefully provide clinicians with the proper diagnostic tools to more specifically treat such patients with improved success in preventing reformation of urinary tract stones after surgery.

    A 38-year-old man visited our hospital complaining of lower urinary tract symptoms. He had undergone extracorporeal shockwave lithotripsy to remove a right renal stone two times when he was 24 years old. Since examinations revealed right staghorn calculi and a giant bladder stone, vesicolithotomy was carried out. The removed stone measured 95 × 75 × 55 mm and weighed 250 g. We hypothesized that a fragment of the upper urinary tract stone had reached the bladder which could not be discharged spontaneously, and grew in the bladder. After the operation, uroflowmetry and voiding cystourethrography were performed and the results indicated no abnormalities in the lower urinary tract function.

    Urinary tract disease is a common reason for use (and likely misuse, improper use, and overuse) of antimicrobials in dogs and cats. There is a lack of comprehensive treatment guidelines such as those that are available for human medicine. Accordingly, guidelines for diagnosis and management of urinary tract infections were created by a Working Group of the International Society for Companion Animal Infectious Diseases. While objective data are currently limited, these guidelines provide information to assist in the diagnosis and management of upper and lower urinary tract infections in dogs and cats. PMID:21776346

    A 16-year-old female presented with dribbling of urine along with voluntary voiding since birth. Renal imaging revealed hydroureteronephrosis on the right side; the uterus and ovary were normal. A radionuclide scan showed a left nonfunctional kidney. On cystovaginoscopy, the urethra was shown to be normal and the urinary bladder was tubular with small capacity and an absent trigone. Although the vagina was capacious, no ureteric orifices were found. Computed tomography corroborated the diagnosis of bilateral, single ectopic ureters draining into a grossly dilated vagina. This case is unique because it is a bilateral single-system ureteral ectopia in a completely differentiated female genital tract that presented late in adolescence. To the best of our knowledge, this is the second such ureteral abnormality reported in the literature so far. The patient underwent ileocystoplasty with right ureteric reimplantation and nephroureterectomy for the left nonfunctional kidney, which histopathology showed to be tuberculosis. The patient is continent with cystometric capacity of more than 300 mL. PMID:23878693

    Imaging technology with its advancement in the field of urology is the boon for the patients who require minimally invasive approaches for various kidney disorders. These approaches require a precise knowledge of the normal and variant anatomy of vascular structures at the hilum of the kidney in terms of their pattern of arrangement and division. The present paper describes a bilateral anomalous arrangement of the structures at the renal hilum as well as their peculiar branching pattern which is of clinical and surgical relevance. Multiple branching of the renal vessels was observed in both kidneys due to which the hila were congested. The right renal artery immediately after its origin divided into 2 branches. The upper branch represented an aberrant artery whereas the lower branch gave 5 divisions. The left renal artery also divided into 2 branches much before the hilum as anterior and posterior divisions. The anterior branch took an arched course and gave 6 branches. The posterior branch gave 3 terminal branches before entering the renal substance. In addition to anomalous hilar structures, normal architecture of both kidneys was altered and the hilum of the left kidney was found on its anterior surface. PMID:23346454

Focal dystonias are especially known in musicians, although little is reported on focal dystonias in athletic stress. The present case report describes the case of a 34-yr-old professional tennis player with bilateral segmental dystonia. The symptoms were expressed in involuntary movements when he intended to hit the ball and in a progredient tremor, initially in one hand, later in both, making him unable to write. The altered mobility during athletic stress was confirmed by video analysis, the altered innervation with excessive, uncoordinated impulse influx by means of electromyography during sport-type specific stress, and writing incapacity during a writing test. The symptoms abated under therapy with trihexyphenidyl-HCL, so that the patient has been able to work as a tennis coach with improved athletic performance for the past 3 yr. It is concluded that the various forms of dystonia should be included in the differential diagnosis of impaired coordinative movements under athletic exercise, especially of the upper extremities.

    Lipogranulomas of the periocular tissues with fulminant fibrotic and lymphohistiocytic responses were initially described in cases of exogenous paraffin or petrolatum jelly injections ("paraffinomas"). A 49-year-old Cambodian woman slowly developed bilateral pseudoptosis with intact levator function and redundant, taut upper eyelid skin. At surgery, vesiculations or "bubbles" in the preaponeurotic fat were encountered and were demonstrated histopathologically to be empty locules surrounded by a thin collagenous lamina. Outside these extracellular spaces were CD68/CD163-positive mononucleated and univacuolated histiocytes simulating damaged fat cells or neoplastic lipoblasts in hematoxylin and eosin sections. Giant cells and chronic sclerosing inflammation were absent. The patient denied any previous injections. The bland character of the lipogranulomas in comparison with that of other injectable agents, the absence of any residual particles associated with other cosmetic fillers, and the distinctive histiocytic response of lipoblast-like cells that were sufficiently characteristic to compel the diagnosis of surreptitious silicone injections. Other conditions were excluded based on comparative clinicopathologic criteria.

    Biomarkers are the measurable changes associated with a physiological or pathophysiological process. Unlike blood, urine is not subject to homeostatic mechanisms. Therefore, greater fluctuations could occur in urine than in blood, better reflecting the changes in human body. The roadmap of urine biomarker era was proposed. Although urine analysis has been attempted for clinical diagnosis, and urine has been monitored during the progression of many diseases, particularly urinary system diseases, whether urine can reflect brain disease status remains uncertain. As some biomarkers of brain diseases can be detected in the body fluids such as cerebrospinal fluid and blood, there is a possibility that urine also contain biomarkers of brain diseases. This review summarizes the clues of brain diseases reflected in the urine proteome and metabolome. PMID:26751805

    In the study of Lin, Wu, Lin, Wu, Wu, Kuo, and Yeung (2012 ), the relationship between the validity of postural movement and bilateral motor integration in terms of sensory integration theory was examined. Postural movement is the ability to use the antigravity postures required for stabilization of the neck, trunk and upper extremities via muscle co-contractions in the neck and upper extremities, and balance. Niklasson's (2013 ) comment argued that postural movement should include primitive reflexes in terms of the general abilities approach. Niklasson (2013 ) focused on the efficacy of the treatment rather than the theoretical frameworks implied in the therapeutic activities. For that purpose Lin, et al. (2012 ) used sensory integration as the theoretical foundation, and the relationship between postural movement and bilateral motor integration was assessed via empirical data. The result of Lin, et al. (2012 ) was offered as a theoretical reference for therapeutic activities.

    Objectives The aims of this study are to highlight the clinicopathological features of urinary bladder cancer in Yemen, and to describe the histological grading of urothelial neoplasms according to the World Health Organization and International Society of Urologic pathology (WHO/ISUP 1998) classification. Methods This is a descriptive record-based study of 316 cases of bladder cancer diagnosed by two pathologists at the Department of pathology, Sana'a University from 1st January 2005 to 30th April 2009. The diagnoses were made on hematoxylin and eosin stained sections and categorized according to WHO/ISUP 1998 classification. Results Out of 316 urinary bladder cancers, 248 (78%) were urothelial neoplasms, 53 (17%) were squamous cell carcinoma, 7 (2%) were adenocarcinoma, and 3 (1%) were rhabdomyosarcoma. The remaining cases were metastatic carcinomas (n=3), small cell carcinoma (n=1), and non-Hodgkin's lymphoma (n=1). The urothelial neoplasms observed were carcinoma in situ 4 (2%), papilloma 7 (3%), papillary urothelial neoplasm of low malignant potential 26 (11%), papillary urothelial carcinoma of low grade 107 (43%), papillary urothelial carcinoma of high grade 18 (7%), and non-papillary urothelial carcinoma of high grade 85 (34%), with 60 years mean age for males and 58 years for females; along with a male to female ratio of 4:1. The peak incidence was observed in the 61-70 years age group. Conclusion This study documents a high frequency of urothelial neoplasms, mostly papillary urothelial carcinoma of low grade and non-papillary urothelial carcinoma of high grade with male preponderance and peak incidence in 6th decade of age.

    We conducted a cross-sectional analysis of individuals 45-79 years old in the National Health and Nutrition Examination Survey III (1988-1994) (NHANES III). Myocardial infarction was determined by electrocardiogram (ECG). Our sample included 4912 participants, which when weighted represented 52,234,055 Americans. We performed adjusted logistic regressions with the Framingham risk score, pack-years of smoking, race-ethnicity, and family history of heart attack, and diabetes as covariates. Urinary cadmium {>=}0.88 {mu}g/g creatinine had an odds ratio of 1.86 (95% CI 1.26-2.75) compared to urinary cadmium <0.43 {mu}g/g creatinine. This result supports the hypothesis that cadmium is associated with coronary heart disease. When logistic regressions were done by gender, women, but not men, showed a significant association of urinary cadmium with myocardial infarction. Women with urinary cadmium {>=}0.88 {mu}g/g creatinine had an odds ratio of 1.80 (95% CI 1.06-3.04) compared to urinary cadmium <0.43 {mu}g/g creatinine. When the analysis was restricted to never smokers (N=2187) urinary cadmium {>=}0.88 {mu}g/g creatinine had an odds ratio of 1.85 (95% CI 1.10-3.14) compared to urinary cadmium <0.43 {mu}g/g creatinine.

    This study aims at evaluating the suitability of adjusting urinary concentrations of arsenic, or any other urinary biomarker, for variations in urine dilution by creatinine and specific gravity in a malnourished population. We measured the concentrations of metabolites of inorganic arsenic, creatinine and specific gravity in spot urine samples collected from 1466 individuals, 5-88 years of age, in Matlab, rural Bangladesh, where arsenic-contaminated drinking water and malnutrition are prevalent (about 30% of the adults had body mass index (BMI) below 18.5 kg/m(2)). The urinary concentrations of creatinine were low; on average 0.55 g/L in the adolescents and adults and about 0.35 g/L in the 5-12 years old children. Therefore, adjustment by creatinine gave much higher numerical values for the urinary arsenic concentrations than did the corresponding data expressed as microg/L, adjusted by specific gravity. As evaluated by multiple regression analyses, urinary creatinine, adjusted by specific gravity, was more affected by body size, age, gender and season than was specific gravity. Furthermore, urinary creatinine was found to be significantly associated with urinary arsenic, which further disqualifies the creatinine adjustment. PMID:17900556

    Abstract The aim of the present study was to determine the distribution of lung blood in a modified bilateral Glenn procedure designed in our institute with lung perfusion scintigraphy. Sixteen consecutive patients who underwent modified bilateral Glenn operation from 2011 to 2014 were enrolled in the study. The control group consisted of 7 patients who underwent bidirectional Glenn shunt. Radionuclide lung perfusion scintigraphy was performed using Tc-99m-macro aggregated albumin (MAA) in all patients. For the patients in modified bilateral Glenn group, the time at which the radioactivity accumulation peaked did not differ significantly between the right and left lung field (t = 0.608, P = 0.554). The incidence of perfusion abnormality in each lung lobe also did not differ significantly (P = 0.426 by Fisher exact test). The radioactive counts were higher in the right lung than in the left lung, but the difference was not statistically significant (t = 1.502, P = 0.157). Radioactive perfusion in the lower lung field was significantly greater than that in the upper field (t = 4.368, P < 0.001). Compared with that in the bidirectional Glenn group, the ratio of radioactivity in the right lung to that in left lung was significantly lower in the modified bilateral Glenn group (t = 3.686, P = 0.002). Lung perfusion scintigraphy confirmed the benefit of the modified bilateral Glenn shunt with regard to more balanced blood perfusion in both lungs. PMID:27661042

    Macrodystrophia lipomatosa is a rare, non-hereditary form of congenital local gigantism characterised by enlargement and hypertrophy of all mesenchymal tissue components with a disproportionate increase in adipose tissue. This form of macrodactyly has been reported in association with other anomalies including polydactyly, brachydactyly, syndactyly, and symphalangism. We describe a previously unreported case of bilateral upper extremity macrodystrophia lipomatosa with syndactyly in a 23-month-old boy. In this report, we emphasise the importance of establishing a diagnosis with imaging and review the described surgical approaches to treating this difficult condition. PMID:24164136

    Canalicular adenoma is a benign neoplasm of the minor salivary glands. The most common site is the upper lip, and the adenoma usually appears as a single lesion. Few cases of multiple foci of canalicular adenoma (CA) have been reported in literature. We report a case of a 78-year-old woman with CA of the nasolabial wrinkle on both sides of the nose, which occurred at the same time. The lesions recurred after about 1 year. This report adds to the literature another case of multiple, bilateral CA with synchronous occurrence.

We report a 10-day-old boy who presented with micrognathia, glossoptosis, and cleft palate as well as multiple congenital anomalies. Ophthalmic examination was notable for bilateral maculopathy, with focal areas of retinal and retinal pigment epithelial atrophy. The association of Pierre Robin sequence and maculopathy has been reported only twice previously.

    An adolescent presented with a rhinosinusitis complicated with bilateral jugular veins and left superior ophthalmic vein thrombosis and respiratory distress with pulmonary hypertension. Blood culture was positive for Haemophilus influenzae and sinus puncture for Streptococcus constellatus. Evolution was under control after 1 week of appropriate antibiotherapy, antithrombotic and anti-inflammatory treatment. He had no neurologic, respiratory or ophthalmologic sequelae 6 months later. Despite lack of pharyngitis or isolation of anaerobic species on blood cultures, the picture was considered compatible with Lemierre syndrome. The risk for such a complication should be considered in cases of severe otorhinolaryngologic infection in young adults. PMID:14643536

    It is suggested that differentiated embryonic cells have a high specificity of molecular constitution as regards the surface layers surrounding their cellular membranes. Correspondingly, specific interface energies may characterize the early contacts between different cell types. The question is raised whether the morphology of the developing embryo may be understood in terms of cellular arrangements which minimize the total interface energy. Bilateral symmetry prevalent in early embryonic development of higher animals might be understood on the basis of the adoption of such a minimum energy principle if, in addition, one assumes that embryonic development is uniquely determined for a particular species.

    We report the case of a 14-year-old boy with bilateral congenital perisylvian syndrome as evidenced by polymicrogyria in the left and right frontotemporal regions, pseudobulbar paresis, seizures, and spastic diplegia. This is the first description of comprehensive neuropsychological assessment in a child with this syndrome. The results reflect significant impairments in auditory processing and independent learning and retention, but relatively preserved cognitive performance on interactive tasks involving frequent feedback and redirection. The findings are interpreted in the context of the neuropathology of this syndrome, with an emphasis on pragmatic implications for rehabilitation. PMID:18618376

    Observation of a case of progressive bilateral parietal thinning within a period of 14 years induced us to study skull films of 3 636 consecutive patients. Parietal thinning was found in 86 patients (2.37%). It was more common in women, with a sex ratio of 1:1.9. The mean age of the females was 72 years, and that of the males 63 years. Previous skull films of 25 of these patients were available and showed progression in 10. It is concluded that parietal thinning is a slowly progressive disease of middle-aged and old patients and is not an anatomical variant or congenital dysplasia of the dipole.

    We present a rare case of bilateral pseudoexfoliative deposits on both intraocular lens (IOL) implants in an 83-year-old woman with no other associated pathology, 5 years after cataract surgery. Pseudoexfoliation syndrome is the most common cause of secondary open-angle glaucoma worldwide and these deposits are usually found on the natural lens. The fact that pseudoexfoliative deposits have been found on IOL implants implies the need for a thorough examination in pseudophakic patients, for it could be the only sign of secondary glaucoma.

    A 51-year-old man developed severe quadriparesis without sensory loss after a fall on the occiput. When he was treated with corticosteroids, the weakness worsened slightly for 2 days, but he then progressively improved and ultimately walked unassisted. Two months later, postmortem examination disclosed metastatic tumors in the superior portion of each precentral gyrus. The subjacent white matter was edematous. No spinal cord abnormalities were found. The clinical, radiologic, and neuropathologic findings suggest that the quadriplegia resulted from these bilateral cerebral lesions and not from spinal cord dysfunction. The rapid development of cerebral edema, perhaps precipitated by trauma, seemed to account for the acute onset of symptoms in this case.

    To determine the usefulness of urinary urea as an index of dietary protein intake, 10 postmenopausal women were enrolled in and completed a randomized, double-blind, cross-over feeding trial from September 2008 to May 2010 that compared 10 days of a 45-g whey supplement with 10 days of a 45-g maltodextrin control. Urinary nitrogen, urinary calcium, urinary urea, and bone turnover markers were measured at days 0, 7, and 10. Paired sample t tests, Pearson's correlation statistic, and simple linear regression were used to assess differences between treatments and associations among urinary metabolites. Urinary nitrogen/urinary creatinine rose from 12.3±1.7 g/g (99.6±13.8 mmol/mmol) to 16.8±2.2 g/g (135.5±17.8 mmol/mmol) with whey supplementation, but did not change with maltodextrin. Whey supplementation caused urinary calcium to rise by 4.76±1.84 mg (1.19±0.46 mmol) without a change in bone turnover markers. Because our goal was to estimate protein intake from urinary nitrogen/urinary creatinine, we used our data to develop the following equation: protein intake (g/day)=71.221+1.719×(urinary nitrogen, g)/creatinine, g) (R=0.46, R(2)=0.21). As a more rapid and less costly alternative to urinary nitrogen/urinary creatinine, we next determined whether urinary urea could predict protein intake and found that protein intake (g/day)=63.844+1.11×(urinary urea, g/creatinine, g) (R=0.58, R(2)=0.34). These data indicate that urinary urea/urinary creatinine is at least as good a marker of dietary protein intake as urinary nitrogen and is easier to quantitate in nutrition intervention trials.

  8. Bilateral transit time assessment of upper and lower limbs as a surrogate ankle brachial index marker.

    Ankle brachial index is useful in monitoring the pathogenesis of peripheral arterial occlusive diseases. Sphygmomanometer is the standard instrument widely used but frequent prolonged monitoring can be less comfortable for patients. Pulse transit time is known to be inversely correlated with blood pressure and a ratio-based pulse transit time measurement has been proposed as a surrogate ankle brachial index marker. In this study, 17 normotensive adults (9 men; aged 25.4 +/- 3.9 years) were recruited. Two postural change test activities were performed to induce changes in the stiffness of the arterial wall of the moved periphery. Results showed that only readings from the limbs that adopted a new posture registered significant blood pressure and pulse transit time changes (P < .05). Furthermore, there was significant correlation between the ankle brachial index and pulse transit time ratio measure for both test activities (R(2) > or = 0.704). The findings herein suggest that pulse transit time ratio is a surrogate and accommodating ankle brachial index marker. PMID:18480079

    Objective Stress urinary incontinence, a major type of urinary incontinence, increases with age and is often developed after partum injury. Low intensity pulsed ultrasound (LIPUS) has been investigated in the treatment of many diseases showing its ability of restoring soft tissue injury. We investigated the therapeutic effect of low intensity pulsed ultrasound in stress urinary incontinence. Methods Thirty-two Sprague Dawley rats in SUI group underwent vaginal distension (VD) and bilateral ovariectomy mimicking partum injury. Eight rats served as mock operation control. Eight rats each in SUI group was treated with low-dosage LESW (0.03 mJ/mm2), medium-dosage LESW (0.06 mJ/mm2), or high-dosage LESW (0.09 mJ/mm2). The rest eight rats served as none-treatment group. For functional study, leak point pressure test (LPP) was performed 2 weeks after the last LESW. Masson trichrome staining was performed to validate the pathological changes. Results The LPP was restored in medium-dosage LESW and high-dosage LESW groups, but not in low-dosage LESW group. More robust striated muscle regeneration was found in these two groups comparing with the none-treatment group. Conclusions LIPUS ameliorate the symptom of SUI via activating striated muscle regeneration.

    Background Urinary schistosomiasis is caused by an intravascular infection with parasitic Schistosoma haematobium worms. The adult worms typically migrate to the venous plexus of the human bladder and excrete eggs which the infected person passes in their urine. Chronic infection can cause substantial morbidity and long-term complications as the eggs become trapped in human tissues causing inflammation and fibrosis. We summarised evidence of drugs active against the infection. This is new edition of a review first published in 1997. Objectives To evaluate the efficacy and safety of drugs for treating urinary schistosomiasis. Search methods We searched the Cochrane Infectious Diseases Group Specialized Register, MEDLINE, CENTRAL, EMBASE and LILACS and reference lists of articles up to 23 May 2014. Selection criteria Randomized controlled trials (RCTs) of antischistosomal drugs and drug combinations compared to placebo, no intervention, or each other. Data collection and analysis Two researchers independently screened the records, extracted the data and assessed risk of bias. The primary efficacy outcomes were parasitological failure (defined as the continued presence of S. haematobium eggs in the urine at time points greater than one month after treatment), and percent reduction of egg counts from baseline. We presented dichotomous data as risk ratios (RR), and continuous data as mean difference (MD), alongside their 95% confidence intervals (CIs). Where appropriate we combined trials in meta analyses or tables. We assessed the quality of evidence using the GRADE approach. Main results We included 30 RCTs enrolling 8165 participants in this review. Twenty-four trials were conducted in children in sub-Saharan Africa, and 21 trials were over 20 years old. Many studies were assessed as being at unclear risk of bias due to inadequate descriptions of study methods. Praziquantel On average, a single 40 mg/kg dose of praziquantel reduced the proportion of people still

    Upper lid blepharoplasty is a common procedure for restoration and rejuvenation of the upper eyelids that can be performed safely and reliably. Understanding the anatomy and aging process of the brow-upper lid aesthetic unit along with properly assessing the excesses and deficiencies of the periorbital region helps to formulate an appropriate surgical plan. Volume deficiency in the aging upper lid may require corrective augmentation. Preexisting asymmetries and ptosis need to be identified and discussed before surgery. Standardized photography along with a candid discussion regarding patients' desired outcomes and realistic expectations are essential to a successful outcome. PMID:27105797

    Background. The risk of ovarian cancer is increased in the association of ovarian tumor, ascites, and hydrothorax with the significant elevated tumor marker CA-125. However, this association can be observed in a rare clinical and benign pathological entity, that is Demons-Meigs' syndrome. Objective. To describe a rare case of Demons-Meigs' syndrome observed in our department. Methods. A black African woman of 35 years old, seventh gravida and fourth parous, underwent a total abdominal hysterectomy with bilateral salpingoophorectomy for large bilateral ovarian masses associated with significant ascites, bilateral pleural effusion, and particular highly elevated tumor marker CA-125 (1835 UI/mL) in a pronounced general alteration condition. Results. The postoperative course was uneventful characterized by a complete remission of hydrothorax and ascites with normal level of CA-125 three months after tumor excision. Histology of both masses revealed a bilateral ovarian fibrothecoma, a benign tumor of the ovary, thus confirming the diagnosis of Demons-Meigs' syndrome. Conclusion. The Demons-Meigs syndrome, although it strongly mimics the clinical picture of malignant metastatic ovarian cancer, remains a disease with benign prognosis after surgical tumor resection. This is a rare condition that must be known and recognized by practitioners to avoid unnecessary practices. PMID:23431489

    Introduction: Patellar tendon rupture can occur due to multiple causes ranging from inflammatory pathologies to episodes of trauma. Extensor mechanism rupture is a rare complication of total knee arthroplasty (TKA). In most of these cases, the failure occurs as avulsion of patellar tendon from tibial tuberosity. We report a rare case with bilateral mid-substance patellar tendon rupture one month after bilateral total knee arthroplasty. Case Presentation: A 69-year-old male was operated for bilateral grade 4 osteoarthritis. On day 30 post-operative, he sustained bilateral patellar tendon rupture while getting up from toilet. He had a history of multiple steroid injections in the knee, which could have affected the tendon. The other etiologies could be inherent weakness of tendon due to diabetes and old age and micro-trauma/stretch associated with sudden correction of previous deformity by TKA. The management in our case was done by primary repair along with augmentation by autologous semitendinosus graft and suture anchor. Conclusion: The operating surgeon must be aware of the possibility of patellar tendon rupture following total knee arthroplasty. This will help the surgeon in early recognition and preparedness to handle such complications, should they arise. Surgeons may consider advising caution to both patient and rehabilitation team in cases with old age, chronic diabetes mellitus, and with a history of steroid injections. PMID:27703942

    The diagnostic strategy for asymptomatic patients with persistent bilateral bilar adenopathy often involves invasive procedures. The authors used Bayesian analysis to: (1) estimate the relative prevalences of diseases causing bilateral bilar adenopathy; (2) assess changes in the prevalence of disease by race, the presence of other clinical symptoms, and geography; and (3) determine the value of relevant noninvasive tests, including the angiotensin-converting enzyme (ACE) assay, gallium scan, and purified protein derivative (PPD), in order to assess when a strategy of watchful waiting is appropriate. The analysis indicated that the ACE assay, particularly when paired with the PPD, can identify many patients who might safely be managed without immediate invasive biopsy. Patients who are ACE+ and PPD- have an estimated probability of sarcoidosis of 0.95 or greater; patients who are ACE- and PPD+ have a probability of tuberculosis of 0.86 if black, 0.79 if white. In contrast, gallium scanning has no diagnostic role in this clinical situation. Bronchoscopic or mediastinoscopic biopsy has a limited role for patients who are ACE+ PPD- or ACE- PPD+ because of limited sensitivity. Patients who are both ACE- and PPD-, particularly if white, may have a high enough risk of lymphoma to consider invasive biopsy.

    We studied the mechanism of song production in the outbred common or domestic canary (Serinus canaria). The contribution that each side of the syrinx makes to song was investigated by observing the effect of unilaterally occluding the left or right primary bronchus, followed by section of the ipsilateral branch of the tracheosyringeal nerve. In other birds with a bilaterally intact vocal system we monitored airflow through each side of the syrinx, together with subsyringeal pressure, during spontaneous song. Song production by domestic canaries is not strongly lateralized as it is in the conspecific song-bred waterslager strain. Some syllables are produced entirely on the left or right side of the syrinx, whereas others contain sequential contributions from each side. Low fundamental frequencies are produced with the left syrinx and high frequencies by the right syrinx, increasing the frequency range of domestic canary song compared to that of the waterslager strain. Midrange frequencies can be generated by either side. Syllables at repetition rates below about 25 s(-1) were accompanied by minibreaths, which were usually bilateral. Unilateral minibreaths were typically on the left side. At higher syllable repetition rates, minibreaths were replaced by a respiratory pattern of pulsatile expiration. Our data show that strong unilateral dominance in song production, present in the waterslager strain, is not a trait of the species as a whole and that the pattern of song lateralization can be altered by selective breeding for particular song characteristics.

    The paper presents the results of gait parameters as a function of unilateral weight. The object of the research was a woman walking on a stationary surface and carrying in his hand weights from 0 to 15 kg. Her movement was recorded by 6 cameras recording the location of 34 markers placed at appropriate points in the body. 3D reconstruction was performed for each of the reflecting markers. Tested signals were changes in the value the joint angles of ankle, knee and hip. On the basis of about 6 cycles of movement of each load, a model for the average gait cycle was developed. The result of the experiments are graphs of changes the joint angles as a function of time, bilateral cyclograms, synchronized bilateral cyclograms and regression lines. The conclusion of the study is to determine how one-sided load affects gait asymmetry. Simple and easy to interpret method of presentation of results were also shown. Studies were conducted using VICON system.

    Background. Despite advances in surgical repair of hiatus hernias, there remains a high radiological recurrence rate. We performed a novel technique incorporating bilateral oesophageal fixation and evaluated outcomes, principally symptom improvement and hernia recurrence. Methods. A retrospective study was performed on a prospective database of patients undergoing hiatus hernia repair with bilateral oesophageal fixation. Retrospective and prospective quality of life (QOL), PPI usage, and patient satisfaction data were obtained. Hernia recurrence was assessed by either barium swallow or gastroscopy. Results. 87 patients were identified in the database with a minimum of 3 months followup. There were significant improvements in QOL scores including GERD HRQL (29.13 to 4.38, P < 0.01), Visick (3 to 1), and RSI (17.45 to 5, P < 0.01). PPI usage decreased from a median of daily to none, and there was high patient satisfaction (94%). 57 patients were assessed for recurrence with either gastroscopy or barium swallow, and one patient had evidence of recurrence on barium swallow at 45 months postoperatively. There was an 8% complication rate and no mortality or oesophageal perforation. Conclusions. This study demonstrates that our technique is both safe and effective in symptom control, and our recurrence investigations demonstrate at least short term durability. PMID:26065030

    antecedentes: el cáncer de mama en el hombre es una enfermedad con baja incidencia, que se reduce aún más cuando es bilateral sincrónica. Existen pocas publicaciones en los últimos años. Objetivo: establecer pautas para el tratamiento de este cáncer, aunque sea infrecuente. Caso clínico: paciente masculino de 75 años de edad, con tumores en ambas mamas, que se le resecaron completamente con exéresis de ganglios palpables. El estudio histopatológico informó que se trataba de un carcinoma ductal infiltrante no especificado. Se indicó tratamiento adyuvante con tamoxifeno y radioterapia; en la actualidad está libre de enfermedad. Conclusiones: el carcinoma mamario bilateral sincrónico en el varón es una enfermedad poco frecuente. Su tratamiento principal es la cirugía, de ahí la importancia del diagnóstico temprano. En la mayoría de los casos se requiere quimioterapia y radioterapia adyuvante porque suelen diagnosticarse en un estadio avanzado.

    Motivation is drawn from the need to determine the sensory cues that animals such as blue crabs and lobsters use to track chemical odor plumes to locate food or mates. Major steps forward with this difficult problem can only be achieved through an appreciation of the spatial and temporal variation of concentration fields and the information content available to a forager in the plume. Here we discuss the usefulness of bilateral comparison to an animal tracking a turbulent plume. Instantaneous concentration fields of a chemical plume diffusing in a fully-developed turbulent open channel flow are measured using planar laser-induced fluorescence (PLIF). The plume is released iso-kinetically 25 mm above the smooth bed (z+ = 90), thus transport is mainly due to advection and ambient turbulence. A spatial correlation function in the spanwise direction is a dramatic indicator of the relative position of the centerline and distance from the source. The relative direction of the plume centerline can be estimated from an instantaneous bilateral comparison provided the sensors are separated by a distance that is relatively large compared to the spanwise integral length scale based on the spatial correlation function.

    Primary aldosteronism due to unilateral aldosterone-producing adenoma (APA) is a surgically curable form of hypertension. Bilateral APA can also be surgically curable in theory but few successful cases can be found in the literature. It has been reported that even using successful adrenal venous sampling (AVS) via bilateral adrenal central veins, it is extremely difficult to differentiate bilateral APA from bilateral idiopathic hyperaldosteronism (IHA) harbouring computed tomography (CT)-detectable bilateral adrenocortical nodules. We report a case of bilateral APA diagnosed by segmental AVS (S-AVS) and blood sampling via intra-adrenal first-degree tributary veins to localize the sites of intra-adrenal hormone production. A 36-year-old man with marked long-standing hypertension was referred to us with a clinical diagnosis of bilateral APA. He had typical clinical and laboratory profiles of marked hypertension, hypokalaemia, elevated plasma aldosterone concentration (PAC) of 45.1 ng dl(-1) and aldosterone renin activity ratio of 90.2 (ng dl(-1) per ng ml(-1 )h(-1)), which was still high after 50 mg-captopril loading. CT revealed bilateral adrenocortical tumours of 10 and 12 mm in diameter on the right and left sides, respectively. S-AVS confirmed excess aldosterone secretion from a tumour segment vein and suppressed secretion from a non-tumour segment vein bilaterally, leading to the diagnosis of bilateral APA. The patient underwent simultaneous bilateral sparing adrenalectomy. Histopathological analysis of the resected adrenals together with decreased blood pressure and PAC of 5.2 ng dl(-1) confirmed the removal of bilateral APA. S-AVS was reliable to differentiate bilateral APA from IHA by direct evaluation of intra-adrenal hormone production. PMID:26538381

    The bilateral advantage for the perception of famous faces was investigated using a redundant target procedure. In experiment 1 we compared simultaneous presentation of stimuli (a) bilaterally and (b) one above the other in the central field. Results showed a redundancy advantage, but only when faces were presented bilaterally. This result lends support to the notion of interhemispheric communication using cross-hemisphere representations. Experiment 2 examined the nature of such communication by comparing bilateral presentation of identical face images, with bilateral presentation of different images of the same person. When asked to make a familiar/unfamiliar face judgement, participants showed evidence for a redundancy advantage under both bilateral conditions. This suggests that the nature of the information shared in interhemispheric communication is abstract, rather than being tied to superficial stimulus properties.

    Urinary incontinence in women has a high prevalence and causes significant morbidity. Given that urinary incontinence is not generally a progressive disease, conservative therapies play an integral part in the management of these patients. We conducted a nonsystematic review of the literature to identify high-quality studies that evaluated the different components of conservative management of stress urinary incontinence, including behavioral therapy, bladder training, pelvic floor muscle training, lifestyle changes, mechanical devices, vaginal cones, and electrical stimulation. Urinary incontinence can have a severe impact on our healthcare system and patients’ quality of life. There are currently a wide variety of treatment options for these patients, ranging from conservative treatment to surgical treatment. Although further research is required in the area of conservative therapies, nonsurgical treatments are effective and are preferred by some patients. PMID:26543427

    Prevalence, pathophysiology, diagnostic and therapeutic approaches of urinary incontinence are well studied in women; however, studies on male urinary incontinence focus on incontinence following surgery of the bladder or prostate, predominantly incontinence after radical prostatectomy. Aging men suffer from incontinence, most frequently urge incontinence (overactive bladder, OAB), nearly as often as women do.The domain of conservative therapy of urinary stress incontinence in men is pelvic floor training. It remains unclear whether biofeedback procedures, electrostimulation therapy, or magnetic stimulation therapy can enhance pelvic floor training. There are data suggesting that an off-label therapy with Duloxetin®, a selective serotonin-noradrenaline reuptake inhibitor (SSNRI), improves urinary incontinence following radical prostatectomy. Antimuscarinic agents in combination with bladder training have been proven as safe and effective treatment in men with OAB. Data, however, suggest that men with OAB are far less frequently treated than women.

    The possibility of urinary tract injury should always be considered in the course of anterior resection or combined abdominoperineal resection of the lower colon and rectum. Controlled studies of ureteral and other injuries and fistulas cannot be made; but fortunately, unanticipated damage to the lower urinary tract does not occur often. The surgeon operating in the pelvis should be aware of the problems rarely encountered and should be capable of their management. If a urologic surgeon is available, consultation often is desirable. Prompt intraoperative recognition is most important so remedial procedures can be carried out immediately. Delay in recognition and treatment jeopardizes the patient's course and the function of the urinary tract. Postoperative urinary tract infections should be diagnosed early so prompt treatment can be instituted. PMID:646493

    Radical cystectomy remains the standard treatment for muscle-invasive carcinoma bladder. Various methods have been described for the urinary diversion. In the last 150 years urinary diversion has evolved from cutaneous ureterostomy to the orthotopic neobladder. Especially during the last 20 years, much advancement has been made. We hereby have reviewed the current approaches being used at different centers in India. We have also analyzed the evolution of diversion from conduit to the orthotopic substitution at our center.

    The purpose of this case-control study was to investigate the relationship between the electrical resistance of the skin at biologically active points (BAPs) on the main meridians and upper gastrointestinal bleeding (UGIB). Electrical resistance to direct current at 20 BAPs on the fingers and toes of 100 patients with (38 men, 12 women; mean age [range], 58.20 ± 19.62 [18-83] years) and without (27 men, 23 women; 49.54 ± 12.12 [22-74] years) UGIB was measured through electrodermal screening (EDS), based on the theory of electroacupuncture according to Voll (EAV). Data were compared through analysis of variance (ANOVA), receiver operating characteristic (ROC) curve analysis, and logistic regression. The initial readings were lower in the UGIB group, indicating blood and energy deficiency due to UGIB. Significant differences in indicator drop values were observed at nine BAPs (p < 0.05) on the bilateral small intestine, bilateral stomach, bilateral circulation, bilateral fibroid degeneration, and right lymph meridians. The area under the ROC curve values of the BAPs on the bilateral small intestine and stomach meridians were larger than 0.5, suggesting the diagnostic accuracy of EDS for UGIB on the basis of the indicator drop of these BAPs. Logistic regression revealed that when the indicator drop of the BAP on the left stomach meridian increased by one score, the risk of UGIB increased by about 1.545-3.523 times. In conclusion, the change in the electrical resistance of the skin measured by EDS at the BAPs on the bilateral small intestine and stomach meridians provides specific information on UGIB.

    Nosocomial urinary tract infections are a common complication in healthcare systems worldwide. A review of the literature was performed in June 2014 using the Medical Literature Analysis and Retrieval System Online (MEDLINE) database, through either PubMed or Ovid as a search engine, to identify publications regarding nosocomial urinary tract infections (NUTIs) definition, epidemiology, etiology and treatment.According to current definitions, more than 30% of nosocomial infections are urinary tract infections (UTIs). A UTI is defined 'nosocomial' (NUTI) when it is acquired in any healthcare institution or, more generally, when it is related to patient management. The origin of nosocomial bacteria is endogenous (the patient's flora) in two thirds of the cases. Patients with indwelling urinary catheters, those undergoing urological surgery and manipulations, long-stay elderly male patients and patients with debilitating diseases are at high risk of developing NUTIs. All bacterial NUTIs should be treated, whether the patient is harboring a urinary catheter or not. The length of treatment depends on the infection site. There is abundance of important guidance which should be considered to reduce the risk of NUTIs (hand disinfection with instant hand sanitizer, wearing non-sterile gloves permanently, isolation of infected or colonized catheterized patients). Patients with asymptomatic bacteriuria can generally be treated initially with catheter removal or catheter exchange, and do not necessarily need antimicrobial therapy. Symptomatic patients should receive antibiotic therapy. Resistance of urinary pathogens to common antibiotics is currently a topic of concern. PMID:25451882

    Among infertile men, a diagnosis of unilateral varicocele is made in 90% of varicocele cases and bilateral in the remaining varicocele cases. However, there are reports of under-diagnosis of bilateral varicocele among infertile men and that its prevalence is greater than 10%. In this prospective study, we aimed to examine the differentially expressed proteins (DEP) extracted from spermatozoa cells of patients with bilateral varicocele and fertile donors. Subjects consisted of 17 men diagnosed with bilateral varicocele and 10 proven fertile men as healthy controls. Using the LTQ-orbitrap elite hybrid mass spectrometry system, proteomic analysis was done on pooled samples from 3 patients with bilateral varicocele and 5 fertile men. From these samples, 73 DEP were identified of which 58 proteins were differentially expressed, with 7 proteins unique to the bilateral varicocele group and 8 proteins to the fertile control group. Majority of the DEPs were observed to be associated with metabolic processes, stress responses, oxidoreductase activity, enzyme regulation, and immune system processes. Seven DEP were involved in sperm function such as capacitation, motility, and sperm-zona binding. Proteins TEKT3 and TCP11 were validated by Western blot analysis and may serve as potential biomarkers for bilateral varicocele. In this study, we have demonstrated for the first time the presence of DEP and identified proteins with distinct reproductive functions which are altered in infertile men with bilateral varicocele. Functional proteomic profiling provides insight into the mechanistic implications of bilateral varicocele-associated male infertility. PMID:25999357

    A 17-year-old teen was hospitalized with bilateral pneumothorax. After the bilateral lungs were expanded using catheter tubes, he fully recovered and he was discharged from our hospital. He had a history of colon perforation. Ehlers-Danlos syndrome (EDS) was suspected due to the combination of colon perforation and pneumothorax, and EDS type IV was confirmed after a genetic study identified a c.1511g>a mutation in the COL3A1 gene. This is the first report of bilateral pneumothorax caused by EDS type IV. Clinicians should consider EDS type IV in the differential diagnosis for bilateral pneumothorax in conjunction with distinct previous histories and radiological findings.

    The purpose of this study was to evaluate the interocular symmetry of several biometric parameters between both eyes. The symmetry between the right and left eye of 397 subjects in 14 biometric parameters, spherical equivalent of refractive error (SE), Jackson crossed cylinder power of refractive error astigmatism with axes at 90° and 180° (RJ0) and at 45° and 135° (RJ45), best-corrected visual acuity (BCVA), average corneal curvature (CC), Jackson crossed cylinder power of corneal astigmatism (CJ0 and CJ45), corneal asphericity coefficient (Q), intraocular pressure (IOP), central corneal thickness (CCT), axial length (AL), anterior chamber depth (ACD), lens thickness (LT) and vitreous chamber depth (VCD), was assessed by comparative data analysis. Aside from RJ0 (p = 0.00), RJ45 (p = 0.02) and Q (p = 0.00), the overall interocular differences of other biometric parameters between fellow eyes were not significant (p > 0.05). The interocular correlation and Bland-Altman plots showed a good agreement between fellow eyes in 14 biometric parameters. Correlations between interocular differences in SE and that in RJ0 (p = 0.03), CC (p = 0.00), AL (p = 0.00) and VCD (p = 0.00) were statistically significant. There were similar strong linear relationships between refractive error astigmatism vectors and corneal astigmatism vectors in bilateral eyes. There were negative correlations of RJ45 and CJ45 between bilateral eyes. A potentially clinically important interocular symmetry in SE, BCVA, CC, CJ0, CJ45, IOP, CCT, AL, ACD, LT and VCD is found in this research, while the differences of RJ0, RJ45 and Q between left and right eyes seem a bit large. The negative interocular relationships of RJ45 and CJ45 demonstrate moderate mirror symmetry exists among fellow eyes. High interocular symmetry in bilateral eyes may be helpful in intraocular lens power calculation, intraocular pressure evaluation, post-operative visual acuity and refraction

  16. Treatment of stress urinary incontinence.

    Fischer-Rasmussen, W

    1990-12-01

    This review presents reported cure and improvement rates of stress urinary incontinence in women obtained by different treatment modalities. Apart from the urodynamic findings, histological and histochemical changes of the pelvic floor may be clinically relevant to treatment in the future. Long-term cure and improvement rates achieved by non-surgical treatment (physiotherapy, biofeedback, bladder training, electrostimulation) are commented on. These rates range from 40-60% for physiotherapy and electrostimulation but are considerably less after biofeedback and bladder training. Pharmacotherapy is unlikely to offer more than a placebo effect. Studies of a single surgical procedure usually report high cure rates. In making the appropriate choice of operation the best guidelines are the cure rates from comparative or prospective randomized reports. From such studies an abdominal retropubic suspension operation (cure rates after five years 57-78 %) is more likely to help the patient than an anterior colporrhaphy (cure rates 31-70 %) or a transvaginal needle bladder neck suspension (cure rates 39-61 %). In selected patients sling procedures or the use of artificial sphincters may produce excellent results (70-80 %). To estimate the results of different treatments urine loss should be assessed objectively and physical restrictions and hygienic and social implications taken into account. A method of pre- and post-treatment "performance scores" should be developed.

    This case demonstrates a rarely reported bilateral scapulohumeral bony ankylosis. A young woman developed extensive heterotopic ossifications (HOs) in both shoulder joints after being mechanically ventilated for several months at the intensive care unit in a comatose status. She presented with a severe movement restriction of both shoulder joints. Surgical resection of the bony bridges was performed in 2 separate sessions with a significant improvement of shoulder function afterwards. No postoperative complications, pain, or recurrence of HOs were noted at 1-year follow-up. Mechanical ventilation, immobilization, neuromuscular blockage, and prolonged sedation are known risk factors for the development of HOs in the shoulder joints. Relatively early surgical resection of the HOs can be performed safely in contrary to earlier belief. Afterwards, nonsteroidal anti-inflammatory drugs and/or radiation therapy can be possible treatment modalities to prevent recurrence of HOs. PMID:27583120

    Bilateral adrenal hemorrhage (BAH) is a rare complication typically seen in critically ill patients, which can lead to acute adrenal insufficiency and death unless it is recognized promptly and treated appropriately. We describe the case of a 64-year-old man with polycythemia vera found to be unresponsive with fever, hypotension, tachycardia, and hypoglycemia. Electrocardiogram showed ST-elevation with elevated troponin, hemoglobin, prothrombin time, and partial thromboplastin time. He required aggressive ventilator and vasopressor support. Despite primary coronary intervention, he remained hypotensive. Random cortisol level was low. He received stress dose hydrocortisone with immediate hemodynamic stability. BAH was highly suspected and was confirmed by non-contrast abdominal computed tomography. Prompt recognition and timely initiated treatment remain crucial to impact the mortality associated with acute adrenal insufficiency. PMID:27609733

    A 57-year-old otherwise healthy woman presented with painless binocular vision loss 1 week after direct application of radiofrequency energy to her orbits. She had no light perception bilaterally. Pupils were dilated and not reactive to light. Fundoscopic exam initially showed optic disc swelling in the right eye and a normal-appearing disc in the left eye. Magnetic resonance imaging of the brain and orbits showed gadolinium enhancement of both intraorbital optic nerves. She underwent a course of high-dose steroid treatment without recovery of vision. Optic discs were pale 11 weeks after injury. With exclusion of other possible causes, this represents a unique case of irreversible binocular optic nerve damage and blindness secondary to radiofrequency exposure. PMID:23271888

    INTRODUCTION Gorlin syndrome (GS), also known as nevoid basal cell carcinoma syndrome (NBCCS), is a rare hereditary, autosomal dominant disease that affects various systems. Its prevalence is estimated at 1/57,000 to 1/256,000 of the population. It is characterized by basal cell carcinomas, multiple odontogenic keratocysts, skeletal abnormalities and ovarian fibroma, among other disorders. PRESENTATION OF CASE To report the case of a young patient with Gorlin syndrome and bilateral ovarian fibroma. DISCUSSION A 20-year old patient with Gorlin syndrome presented with facial asymmetry, broad nasal root, dental abnormalities, micrognathism, convergent strabismus, multiple pigmented lesions on the trunk and face, pectus excavatum, kyphoscoliosis and a palpable mass in the abdomen occupying the entire pelvic region. CONCLUSION Gorlin–Goltz syndrome is a hereditary pathology that includes numerous clinical manifestations. Diagnosis is clinical and genetic confirmation is unnecessary. PMID:22771908

    We report a case of very rare adrenal tumor. A 54-year-old patient was classified as affected by bilateral adrenal incidentaloma that surprisingly, on histology resulted solitary fibrous tumors. Solitary fibrous tumor (SFT) is an uncommon mesenchymal neoplasm. Only five cases of localization of SFT in adrenal gland are reported in the literature, while the frequency of retroperitoneum localization is more frequent, about 30 cases. Immunohistochemically, SFT can be positive for CD34 antigen, vimentin, CD99, and bcl-2 and usually negative for cytokeratins, chromogranin A, NSE, neurofilaments, synoptophysin, and S-100. Surgical excision remains the main treatment in fact the recurrence is locoregional and correlated with positive margins due to incomplete excision, while distant metastases are correlated with atypical or malignant features.

    Bilateral coronoid hyperplasia causes painless progressive trismus, resulting from coronoid process impingement on the posterior aspect of the zygomatic bone. The etiology of coronoid hyperplasia is unclear, with various theories proposed. An endocrine stimulus, increased temporalis activity, trauma, genetic inheritance and familial occurrence have all been proposed, but no substantive evidence exists to support any of these hypotheses. Multiplanar reformatting of axial scans and 3-dimensional reconstruction permit precise reproduction of the shape and size of the coronoid and malar structures, and relationships of all structures of the temporal and infratemporal fossae. This case shows remarkably increased mouth opening by coronoidectomy in a patient who complained of trismus due to hyperplasia of coronoid process. PMID:27489829

    Summary Our patient had drainage of a large amoebic liver abscess. This got complicated by a severe degree of hypotension, which required aggressive fluid resuscitation and hydrocortisone support. Computerised tomography (CT) of the abdomen revealed bilateral adrenal gland haemorrhage (BAH) resulting in primary adrenal gland failure, which was the cause for hypotension. Patient was on long-term warfarin for provoked deep vein thrombosis of lower limb, which was discontinued before the procedure. Thrombophilia profile indicated the presence of lupus anticoagulant factor with prolonged activated partial thromboplastin time (aPTT). Patient was discharged on lifelong warfarin. This case emphasises the need for strong clinical suspicion for diagnosing BAH, rare but life-threatening condition, and its association with amoebic liver abscess and anti-phospholipid antibody syndrome (APLS). Learning points Recognition of BAH as a rare complication of sepsis.APLS can rarely cause BAH. PMID:25276353

    Abstract Cherubism is a rare, nonneoplastic, self-limiting fibro-osseous that occurs in children. Affected children usually appear normal at birth. Lesions are characterized by the replacement of bone with fibrovascular tissue containing many multinucleated giant cells. Most studies have reported cherubism to be familial and with bilateral involvement of the mandibles. The authors describe a nonfamilial case of cherubism, involving both the mandible and the maxilla, in a 4-year-old female child with slowly enlarging, painless, symmetrical swelling of both cheeks. Cherubism is a rare disease that is usually limited to the mandible, but the maxilla may be involved. Computed tomography scan and biopsy are helpful for early diagnosis. PMID:26656340

    A 40-year-old male presented to our outpatient department with the chief complaint of a painless mass on his right testis with gradual size increase over the past two months. Physical examination and ultrasound revealed a firm and nontender mass both on the right and on the left testis. The only elevated biomarker was b-hcG (24,7 mIU/mL) and computer tomography (CT) did not reveal any pathology. Bilateral high orchiectomies were performed, without previous frozen storage of the sperm. Histology proved typical seminoma of the left testis and embryonal carcinoma of the right testis. He received two cycles of adjuvant combination chemotherapy with bleomycin, etoposide, and cisplatin. Six months after the operation no residual tumor or recurrence was observed. PMID:26060594

    A 40-year-old male paddy field worker was referred for exertional shortness of breath and non-productive cough for 4 years. He had been treated for pulmonary tuberculosis twice. Chest radiograph showed extensive bilateral nodular opacities ("sandstorm-like") in the middle and lower lobe. Pulmonary function tests revealed a restrictive ventilatory defect. High resolution CT showed widespread nodular infiltration with "crazy paving" appearance and interrupted black pleura sign. This was confirmed as pulmonary alveolar microlithiasis (PAM) by trans-bronchial lung biopsy, which showed normal respiratory lining epithelium with dilated alveolar spaces containing many calcific bodies, some of which showed concentric calcification. The possibilities of silicosis (due to exposure to husk) and tuberculosis, both of which can mimic PAM clinically and radiologically, made this case a diagnostic challenge. PMID:21686505

    A paradigmatic example of an emotional bias in decision making is the framing effect, where the manner in which a choice is posed--as a potential loss or a potential gain--systematically biases an ensuing decision. Two fMRI studies have shown that the activation in the amygdala is modulated by the framing effect. Here, contrary to an expectation based on these studies, we show that two patients with Urbach-Wiethe (UW) disease, a rare condition associated with congenital, complete bilateral amygdala degeneration, exhibit an intact framing effect. However, choice preference in these patients did show a qualitatively distinct pattern compared to controls evident in an increased propensity to gamble, indicating that loss of amygdala function does exert an overall influence on risk-taking. These findings suggest either that amygdala does contribute to decision making but does not play a causal role in framing, or that UW is not a pure lesion model of amygdala function.

    Current models of bilateral trade neglect the effects of income distribution. This paper addresses the issue by accounting for non-homothetic consumer preferences and hence investigating the role of income distribution in the context of the gravity model of trade. A theoretically justified gravity model is estimated for disaggregated trade data (Dollar volume is used as dependent variable) using a sample of 104 exporters and 108 importers for 1980-2003 to achieve two main goals. We define and calculate new measures of income distribution similarity and empirically confirm that greater similarity of income distribution between countries implies more trade. Using distribution-based measures as a proxy for demand similarities in gravity models, we find consistent and robust support for the hypothesis that countries with more similar income-distributions trade more with each other. The hypothesis is also confirmed at disaggregated level for differentiated product categories.

    For more than a hundred years, it has been supposed that canine guidance should be avoided in conventional complete dentures, since it would result in denture instability. Thus, bilateral balanced articulation has been held by many authors as fundamental for treatment success. However, randomized clinical trials have shown that balanced articulation is not as important as previously thought. The issue about which occlusal concept is the most appropriate for individual needs is clinically and economically relevant for both the dentist and dental technician. Therefore, the purpose of this study is to provide an evidence-based update on complete denture occlusion. Clinical Relevance: The issue about which occlusal concept is the most appropriate for individual needs is clinically and economically relevant. PMID:25073224

    This case demonstrates a rarely reported bilateral scapulohumeral bony ankylosis. A young woman developed extensive heterotopic ossifications (HOs) in both shoulder joints after being mechanically ventilated for several months at the intensive care unit in a comatose status. She presented with a severe movement restriction of both shoulder joints. Surgical resection of the bony bridges was performed in 2 separate sessions with a significant improvement of shoulder function afterwards. No postoperative complications, pain, or recurrence of HOs were noted at 1-year follow-up. Mechanical ventilation, immobilization, neuromuscular blockage, and prolonged sedation are known risk factors for the development of HOs in the shoulder joints. Relatively early surgical resection of the HOs can be performed safely in contrary to earlier belief. Afterwards, nonsteroidal anti-inflammatory drugs and/or radiation therapy can be possible treatment modalities to prevent recurrence of HOs. PMID:27583120

    Taurodontism is a rare dental anomaly in which there is an enlarged pulp chamber at the expense of roots with apical displacement of the pulpal floor, giving it a rectangular shape. It is caused by the failure of Hertwig's epithelial root sheath to invaginate at the proper horizontal level. Taurodontism has been reported as an intraoral feature of several syndromes like Down syndrome, Klinefelter syndrome, Smith-Magenis syndrome, Hurler syndrome, etc. Association of taurodontism with hypodontia in permanent dentition has also been reported. Taurodontism in primary dentition and its association with hypodontia is very rarely reported in the literature. The present case illustrates bilateral taurodontism of primary mandibular molars with hypodontia in maxilla. PMID:23345504

    We report the case of a 57-year-old right-handed woman, with a history of hypertension, who, in February 1990, suddenly developed behavioral and cognitive abnormalities. Prior to the onset of her illness she had been normal. On examination, neuropsychological testing (Wechsler Mental Test, Wechsler Adult Intelligence Scale Revised, Knox Cube Test) elicited attention abnormalities, decreased recent memory, apathy, reduced spontaneity and initiative and left hemiparesia. CT scan showed small low density areas in the head of both caudate nuclei and right internal capsule, indicating infarction. Two years later, the deficit had partially resolved. Apathy persisted; psychometry showed an IQ of 57. Bilateral damage to the head of the caudate nuclei disrupt cortical-subcortical connections. The caudate nucleus is an essential component of basal ganglia-thalamo-cortical circuitry and its contribution to cognitive functions and behavior appears to be important. PMID:7801044

    Rotational vertebral artery occlusion, or bow hunter's stroke, is reversible, positional symptomatic vertebrobasilar ischemia. The typical mechanism of action is obstruction of a dominant vertebral artery with contralateral head rotation in the setting of baseline ipsilateral vertebral artery stenosis or occlusion. Here we present a rare case of mechanical occlusion of bilateral patent vertebral arteries manifesting as near syncope with rightward head rotation. Diagnostic cerebral angiography showed dynamic right C5 vertebral occlusion and left C2 vertebral occlusion. The patient underwent right C4/5 transverse process decompression. Postoperative angiogram showed patent flow through the right vertebral artery in neutral position and with head turn with resultant resolution of symptoms. PMID:23465174

    Aim: To study the potential of BLCA1 for detection of urothelial cancer including urinary bladder cancer (UBC) and upper tract urothelial cancer (UTUC). Method: An antibody for BLCA1 was generated and indirect ELISA was used to detect urinary BLCA1 level. Clinicopathological parameters were studied for the association with BLCA1 level. Urine samples from UBC and UTUC patients, together with cases with other urological disorders were collected and tested. Results: Urinary BLCA1 level in UBC and UTUC patients were significantly higher than that in normal controls. This was also proven when urothelial cancers were grouped as a whole, where as the level did not differ between UBC and UTUC samples. BLCA1 was also significantly higher in urothelial cancer samples compared to other urological disorders such as patients with long-dwelling catheter, glandular cystitis, BPH and other benign conditions. Cut-off value at 0.0009 OD/μg yielded a sensitivity of 92.7% and a specificity of 92.9% for UBC. Conclusion: Urinary BLCA1 is a promising marker for urothelial cancers including UBC and UTUC with high sensitivity and specificity. PMID:26770501

    Urinary retention is the inability to empty the bladder completely, and may result from bladder hypocontractility, increases in outlet resistance or both. Chronic urinary retention can lead to several urological complications and is often refractory to pharmacologic, behavioral and surgical treatments. We sought to determine whether electrical stimulation of sensory fibers in the pudendal nerve could engage an augmenting reflex and thereby improve bladder emptying in an animal model of urinary retention. We measured the efficiency of bladder emptying with and without concomitant electrical stimulation of pudendal nerve afferents in urethane-anesthetized rats. Voiding efficiency (VE = voided volume/initial volume) was reduced from 72 ± 7% to 29 ± 7% following unilateral transection of the sensory branch of the pudendal nerve (UST) and from 70 ± 5% to 18 ± 4% following bilateral transection (BST). Unilateral electrical stimulation of the proximal transected sensory pudendal nerve during distention-evoked voiding contractions significantly improved VE. Low-intensity stimulation at frequencies of 1-50 Hz increased VE to 40-51% following UST and to 39-49% following BST, while high-intensity stimulation was ineffective at increasing VE. The increase in VE was mediated by increases in the duration of distention-evoked voiding bladder contractions, rather than increases in contraction amplitude. These results are consistent with an essential role for pudendal sensory feedback in efficient bladder emptying, and raise the possibility that electrical activation of pudendal nerve afferents may provide a new approach to restore efficient bladder emptying in persons with urinary retention.

    Human bocavirus (HBoV), that was first identified in 2005 and classified in Parvoviridae family, is a small, non-enveloped, single-stranded DNA virus, responsible for upper and lower respiratory tract infections, especially in young children. Although HBoV generally causes self-limited influenza-like illness, it may also lead to pneumonia, bronchiolitis, croup and asthma attacks. In this report, a case of acute bronchiolitis complicated with pneumomediastinum and bilateral pneumothorax caused by HBoV has been presented. A three-year-old boy was referred to our pediatric intensive care unit with a two day history of fever, tachypnea, hypoxia and respiratory failure. On auscultation, there were widespread expiratory wheezing and inspiratory crackles. The chest radiography yielded paracardiac infiltration and air trapping on the right lung and infiltration on the left lung. The patient had leukocytosis and elevated C-reactive protein level. On the second day of admission, respiratory distress worsened and chest radiography revealed right pneumothorax and subcutaneous emphysema in bilateral cervical region and left chest wall. He was intubated because of respiratory failure. In the thorax computed tomography, pneumomediastinum and bilateral pneumothorax were detected and right chest tube was inserted. Repetitive blood and tracheal aspirate cultures were negative. A nasopharyngeal swab sample was analyzed by multiplex real-time polymerase chain reaction method with the use of viral respiratory panel (FTD(®) Respiratory Pathogens 21 Kit, Fast-Track Diagnostics), and positive result was detected for only HBoV. On the ninth day of admission, pneumomediastinum and bilateral pneumothorax improved completely and he was discharged with cure. In conclusion, HBoV bronchiolitis may progress rare but severe complications, it should be kept in mind as an etiological agent of the respiratory tract infections especially children younger than five years old.

  1. Two types of bilateral symmetry in the Metazoa: chordate and bilaterian.

    The chordate sagittal plane is perpendicular to the sagittal plane primitive for the bilaterally symmetrical metazoans (Bilateria). The earliest metazoans, when symmetrical at all, were probably radial in symmetry. The axis of symmetry was vertical and the mouth, when present, opened either upward or downward. The Bilateria evolved from the primitive metazoan condition by acquiring bilateral symmetry, mesoderm, a brain at the anterior end and protonephridia. Perhaps in the stem lineage of the Bilateria a hydroid-like or medusoid-like ancestor fell over on one side onto a substrate (pleurothetism). If so, the anteroposterior axis of Bilateria would be homologous with the vertical axis of radial symmetry in coelenterates. The bilaterian plane of symmetry arose to include the anteroposterior axis. The Deuterostomia (the Hemichordata, Echinodermata and Chordata) evolved within the Bilateria by producing the mouth as a secondary perforation. Within the deuterostomes the echinoderms and chordates constitute a monophyletic group named Dexiothetica. Hemichordates retain the primitive bilaterian sagittal plane. The Dexiothetica derive from an ancestor like the present-day hemichordate Cephalodiscus which had lain down on the primitive right side (dexiothetism) and acquired a calcite skeleton. The echinoderms evolved from this ancestor by losing the ancestral locomotory tail and gill slit, becoming static, moving the mouth to the centre of the new upper surface and developing radial pentameral symmetry. The chordates evolved from the same ancestor by developing a notochord in the tail, losing the water vascular system, evolving a filter-feeding pharynx and developing a new vertical plane of bilateral symmetry perpendicular to the old bilaterian plane. Evidence derived from certain bizarre Palaeozoic marine fossils (calcichordates) gives a detailed history of the early evolution of echinoderms and chordates and shows how the new bilateral symmetry was gradually acquired in

    1994-12-01

    We studied renal function an average of 44 months after simultaneous bilateral renal SWL in 56 patients. No cases of clinically apparent acute renal failure occurred in the early postoperative period. The glomerular filtration rate (GFR) was calculated using an empiric formula having a significant correlation with measured creatinine clearance, and a change of 20% or greater was considered a clinically significant deterioration in renal function. Of the seven patients with a preoperative serum creatinine concentration of > 1.5 mg/dL, six had an average increase of 35% in postoperative GFR attributable to relief of obstruction, while one had a 30% reduction in GFR. Among 49 patients with a preoperative serum creatinine concentration of 1.5 mg/dL or less, there was an increase in postoperative GFR in 22 patients (45%), no change in 3 (6%), and a decrease in 24 (49%), who had a higher number of multiple renal stones (p < 0.05) and of repeat SWL (p = 0.08). Nine of them (18%) had a clinically significant decrease in GFR of > 20%. A review of the literature showed a long-term reduction of function in the individual human kidney after SWL in some cases of a solitary kidney and in some cases with an untreated contralateral kidney. Because there is no evidence that an untreated contralateral kidney aids the long-term recovery of the function of a treated kidney in all cases, simultaneous or separate bilateral renal SWL would not influence this long-term reduction in renal function, which was felt to occur with multiple renal stones and repeat SWL.

    Antecedentes: el linfoma de Burkitt es una forma agresiva de los linfomas no Hodgkin de células B que ocurre con mayor frecuencia en niños y adultos jóvenes; el linfoma de ovario puede aparecer como lesión primaria o, más comúnmente, como una metástasis. Las lesiones primarias de ovario son manifestaciones raras que corresponden a 0.5% de los linfomas no Hodgkin y 1.5% de los tumores de ovario. Caso clínico: paciente femenina de 31 años de edad, con debilidad generalizada, incapacidad para la marcha, disnea, hiporexia, fiebre, diaforesis, pérdida de 20 kg de peso, abdomen plano, con dolor abdominal; Ca125 610 U/mL. La tomografía computada abdominal mostró un gran tumor de aspecto sólido que afectaba a la cavidad pélvica derecha. Se extirparon los tumores ováricos bilaterales. Desde el punto de vista microscópico ambas lesiones muestran una imagen en "cielo estrellado" compuesta por un patrón de infiltrado monótono de linfocitos mezclada con macrófagos de citoplasma amplio y claro, abundantes mitosis atípicas, zonas de necrosis y hemorragia. La inmunohistoquímica reveló positividad para CDI0 y CD20, negativo con CD3, índice de proliferación Ki67 alto. Se diagnosticó linfoma tipo Burkitt bilateral de ovario. Conclusiones: el linfoma de Burkitt de ovario bilateral es poco frecuente, con variabilidad de presentación; el dolor abdominal y los tumores abdominales son lo más frecuente. El pronóstico a corto plazo de las pacientes es malo, por lo que es necesario conocer esta afección para poder establecer el diagnóstico temprano.

    Recent findings indicate that conscious attention is related to large-scale information integration of various brain regions, including both hemispheres, that enables integration of parallel distributed modalities of processed information. There is also evidence that the level of information transference related to integration or splitting among brain regions, and between hemispheres, establishes a certain level of efficiency of the information processing. The level of information transference also may have modulatory influences on attentional capacity that are closely linked to the emotional arousal and autonomic response related to a stimulus. These findings suggest a hypothesis that changes in conscious attention, specifically during meditation could be reflected in the autonomic activity as the left-right information transference calculated from bilateral electrodermal activity (EDA). With the aim to compare conscious attention during meditation with other attentional states (resting state, Stroop task, and memory task), we performed bilateral EDA measurement in 7 healthy persons during resting state, Stroop task, neurofeedback memory test, and meditation. The results indicate that the information transference (ie, transinformation) is able to distinguish those attentional states, and that the highest level of the transinformation has been found during attentional processing related to meditation, indicating higher level of connectivity between left and right sides. Calculations other than pointwise transinformation (PTI) performed on EDA records, such as mean skin conductance level or laterality index, were not able to distinguish attentional states. The results suggest that PTI may present an interesting method useful for the assessment of information flow, related to neural functioning, that in the case of meditation may reflect typical integrative changes in the autonomic nervous system related to brain functions and focused attentional processing.

  12. Orthodontic-surgical treatment after posttraumatic bilateral condylectomy of the mandible in an adult patient.

    PubMed

    2003-01-01

    A posttraumatic open bite associated with a bird face is reported. Condylectomy was indicated in relation to the plurifragmentary fracture of the condyles with limitation of mandibular movement. Condylectomies were mandatory as a result of delayed maxillofacial surgical treatment, which was related to the poor general condition of the patient after trauma. Functional disorder recovery and aesthetic deformity correction were planned by a team approach between orthodontists and maxillofacial surgeons with the support of a logopedist for the postural-related muscle problems. The main practical and theoretical problems presented by the clinical case were a result of the need to restore the occlusal relations and to avoid recurrence of open bite in this patient. The patient presented a wide alteration of muscular function and a strength fibrotic retraction with alteration in the relationship between upper and lower jaws and retrusion of the mandible associated to open bite. Orthodontic treatment was carried with no impact on the upper and lower axis, avoiding orthodontic correction of the open bite. Surgery corrected both the open bite and the bird face by means of bilateral sagittal split osteotomies. Wiring of the mandibular osteotomies and intermaxillary fixation allowed positioning of the mandibular ramus bilaterally because of the fibrosis and muscular action-related forces without resulting in a similar rotation of the mandible with the risk of recurrence. Myotherapy and logopedic support minimized the risk of recurrence, improved reduction of muscular tension with the resolution of the lip incompetence, and allowed functional recovery of mandibular movements.

    2002-09-01

    We present the results from the evaluations of three children ages of 2, 7, and 11 years with hemiparesis and multiple white-matter lesions on magnetic resonance images (MRIs). The initial symptoms were mainly acute/subacute hemiparesis in all and headache/vomiting in one of them. Before admission, one of them had a history of upper respiratory tract infection, whereas another had undergone urinary tract surgery, and the other reported no history of any infection or stress-related factor. In all of the children, MRI showed multiple superficial and deep white-matter hyperintensity in T2-weighted and proton density images with perifocal edema in the acute phase. During the symptomatic period, all of the patients underwent corticosteroid treatment. Whereas two of the patients demonstrated signs of recovery during the first week of treatment, the other patient demonstrated almost a full recovery with minimal neurologic sequela. Follow-up MRI demonstrated not only a remarkable decrease in the size and number of the lesions, with complete resolution for many of them, it also demonstrated a loss of contrast enhancement. None of these three patients, who had been followed up clinically and through MRI for 5 years, have shown either a clinical relapse or new lesions. The clinical pictures and MRI of the children were different in some aspects from acute multiple sclerosis and acute disseminated encephalomyelitis. Regarding both the clinical follow-up and treatment strategy, it is essential and interesting to state the fact that tumefactive lesions involving both hemispheres are likely to appear during the monitoring of the monophasic courses among inflammatory demyelinating diseases of childhood such as acute disseminated encephalomyelitis.

    Chronic kidney disease and upper tract urothelial carcinomas display a bidirectional relationship. Review of the literature indicates that early diagnosis and correct localization of upper tract urothelial carcinomas in dialysis patients and kidney transplant recipients are important but problematic. Urine cytology and cystoscopy have limited sensitivity for the diagnosis of upper tract urothelial carcinomas in dialysis patients. Enhanced computed tomography and magnetic resonance imaging could prove useful for the detection and staging of upper tract urothelial carcinomas in dialysis patients. Renal ultrasound can detect hydronephrosis caused by upper tract urothelial carcinomas in kidney transplant recipients but cannot visualize the carcinomas themselves. High detection rates for upper tract urothelial carcinomas in kidney transplant recipients have recently been demonstrated using computed tomography urography, which appears to be a promising tool. To detect carcinomas in dialysis patients and kidney transplant recipients as early as possible, regular screening in asymptomatic patients and diagnostic work-up in symptomatic patients should be performed using a combination of urological and imaging methods. Careful assessment of subsequent recurrence within the contralateral upper urinary tract and the urinary bladder is necessary for dialysis patients and kidney transplant recipients with upper tract urothelial carcinomas.

    BACKGROUND: Urinary incontinence is a common problem for adult women. It results in a large financial and psychosocial cost. Much urinary incontinence goes unreported. Women with urinary incontinence can be successfully assessed and treated in general practice but studies have shown that many GPs manage the condition inadequately. AIM: This study aims to examine GPs' awareness of urinary incontinence in women and their management of, and attitudes to, female urinary incontinence. METHOD: A qualitative study was conducted with 21 GPs responding to semi-structured interviews. Thematic analysis was carried out on these interviews, with recurrent views and experiences being identified and grouped. RESULTS: The interviews of 11 male and nine female GPs were suitable for analysis. GPs were aware of the prevalence and under-reporting of urinary incontinence in women. Many were unhappy with their own management of the condition and with the management options available to them. Male GPs in particular were reluctant to carry out gynaecological examinations, and few GPs expressed enthusiasm for teaching pelvic floor exercises or bladder drills. Medications were frequently used but generally considered ineffective or intolerable. The services of both public health nurses and practice nurses were under-used, largely because of lack of training in this area. Although incontinence nurses were employed in the area, many GPs did not know of their availability and, of those who did, few referred to them more than infrequently. CONCLUSION: This study demonstrates that many GPs avoid dealing with the problem of urinary incontinence in women and that they find it to be a difficult, chronic problem to treat. Specialist options seem not to be useful in general practice. The findings need to be explored in other GP settings. PMID:9624768

    Various crystals are seen in human urine. Some of them, particularly calcium oxalate dihydrate, are seen normally. Pathological crystals indicate crystal formation initiating urinary stones. Unfortunately, many of the relevant crystals are not recognized in light microscopic analysis of the urinary deposit performed in most of the clinical laboratories. Many crystals are not clearly identifiable under the ordinary light microscopy. The objective of the present study was to perform scanning electron microscopic (SEM) assessment of various urinary deposits and confirm the identity by elemental distribution analysis (EDAX). 50 samples of urinary deposits were collected from urinary stone clinic. Deposits containing significant crystalluria (more than 10 per HPF) were collected under liquid paraffin in special containers and taken up for SEM studies. The deposited crystals were retrieved with appropriate Pasteur pipettes, and placed on micropore filter paper discs. The fluid was absorbed by thicker layers of filter paper underneath and discs were fixed to brass studs. They were then gold sputtered to 100 A and examined under SEM (Jeol JSM 35C microscope). When crystals were seen, their morphology was recorded by taking photographs at different angles. At appropriate magnification, EDAX probe was pointed to the crystals under study and the wave patterns analyzed. Components of the crystals were recognized by utilizing the data. All the samples analyzed contained significant number of crystals. All samples contained more than one type of crystal. The commonest crystals encountered included calcium oxalate monohydrate (whewellite 22%), calcium oxalate dihydrate (weddellite 32%), uric acid (10%), calcium phosphates, namely, apatite (4%), brushite (6%), struvite (6%) and octocalcium phosphate (2%). The morphological appearances of urinary crystals described were correlated with the wavelengths obtained through elemental distribution analysis. Various urinary crystals that

    The majority of nursing home residents experience some type of urinary incontinence. Other bladder-related disorders (eg, urinary retention and urinary tract infection) also are common in long-term care facilities. Efforts to manage urological conditions such as the use of indwelling catheters and absorbent products, perineal hygiene and care, toileting, and bladder rehabilitation are areas of concern and have become the subject of revised regulations. The intent of recent changes to the Centers for Medicare and Medicaid Services surveyor guidance for incontinence and urinary catheters is to ensure that: 1) incontinent residents are identified, assessed, and provided appropriate treatment, 2) indwelling catheters are not used without medical justification and removed as soon as clinically warranted, and 3) residents receive appropriate care to prevent urinary tract infections. Nursing homes must implement policies, procedures, and programs to help restore bladder function and continence in order to improve quality-of-life for nursing home residents.

    Compared to lower limb arterial diseases, upper limb arterial diseases look rare, heterogeneous with various etiologies and a rather vague clinical picture, but with a negligible risk of amputation. Almost all types of arterial diseases can be present in the upper limb, but the anatomical and hemodynamic conditions particular to the upper limb often confuse the issue. Thus, atherosclerosis affects mainly the subclavian artery in its proximal segment where the potential of collateral pathway is high making the symptomatic forms not very frequent whereas the prevalence of subclavian artery stenosis or occlusion is relatively high. The clinical examination and the etiologies are discussed according to the clinical, anatomical and hemodynamic context.

  19. [Urinary urgency and reflex incontinence].

    PubMed

    Madersbacher, H

    1991-07-01

    Urge and reflex incontinence are caused by detrusor dysfunction:urgency may be due to hyperactivity or hypersensitivity of the bladder. Neurogenic hyperactivity of the detrusor is called detrusor hyperreflexia: the neurogenic uninhibited bladder is caused by incomplete, and the so-called reflex bladder by complete, suprasacral lesions. The pathophysiology of symptomatic and idiopathic detrusor hyperactivity and the therapeutic armentarium are described. Bladder drill together with biofeedback and pharmacotherapy with spasmolytic drugs - several potent spasmolytic drugs with different modes of action are available - are the basis of treatment for hyperactivity and hypersensitivity of the detrusor. An alternative is electrostimulation: stimulation of the afferents of the pudendal nerve, via the pelvic floor (anal, vaginal), percutaneously (dorsal nerve of the penis, clitoric nerve) or by the implantation of electrodes results in inhibition of the detrusor. Most (80-90%) patients can be treated successfully by conservative means. Operative measurements comprise bladder denervation and bladder augmentation. The results of bladder denervation by transtrigonal phenolization of the pelvic plexus are highly controversial. In patients with uncontrollable hyperactivity of the detrusor, augmentation of the bladder (e.g. clam ileocystoplasty) is the method of choice, while for those with uncontrollable hypersensitivity of the detrusor, cystectomy followed by bladder substitution should be performed as a last resort. Treatment for urinary incontinence due to detrusor hyperreflexia must be selected bearing in mind that bladder emptying is inadequate, in most cases because of dyssynergia between detrusor and external sphincter. Therapy is basically aimed at transforming hyperreflexia of the detrusor into hyporeflexia, primarily by potent spasmolytic drugs.(ABSTRACT TRUNCATED AT 250 WORDS)

    In this paper, we introduce a high efficient and practical disparity estimation using hierarchical bilateral filtering for real-time view synthesis. The proposed method is based on hierarchical stereo matching with hardware-efficient bilateral filtering. Hardware-efficient bilateral filtering is different from the exact bilateral filter. The purpose of the method is to design an edge-preserving filter that can be efficiently parallelized on hardware. The proposed hierarchical bilateral filtering based disparity estimation is essentially a coarse-to-fine use of stereo matching with bilateral filtering. It works as follows: firstly, the hierarchical image pyramid are constructed; the multi-scale algorithm then starts by applying a local stereo matching to the downsampled images at the coarsest level of the hierarchy. After the local stereo matching, the estimated disparity map is refined with the bilateral filtering. And then the refined disparity map will be adaptively upsampled to the next finer level. The upsampled disparity map used as a prior of the corresponding local stereo matching at the next level, and filtered and so on. The method we propose is essentially a combination of hierarchical stereo matching and hardware-efficient bilateral filtering. As a result, visual comparison using real-world stereoscopic video clips shows that the method gives better results than one of state-of-art methods in terms of robustness and computation time.

    Transient osteoporosis of the hip (TOH) is a rare disorder characterized by acute severe coxalgia and temporary osteopenia in the proximal femur. Although most cases were unilateral or staged bilateral TOH, some authors reported that the pregnant patients simultaneously had TOH in their bilateral hips. However, there has been no report of simultaneous bilateral TOH in the patient without pregnancy. A 25-year-old Japanese woman without pregnancy had acute simultaneous bilateral hip pain. Plain X-ray of the bilateral hips did not show a periarticular osteopenia. However, magnetic resonance image obtained one week after the onset demonstrated increased T2-weighted signal intensity and decreased T1-weighted signal intensity in the bilateral femoral heads. She was treated conservatively, and follow-up magnetic resonance image at seven weeks after the onset returned to normal bone marrow signal intensity. Her bilateral coxalgia subsided gradually. At one year after the onset, she had no sign of symptomatic flair. Our experience with this case indicates that recognizing the possibility of simultaneous bilateral TOH is important unless the patient is pregnant, and magnetic resonance image is predictable test to make a diagnosis of TOH, even in the absence of abnormal finding on plain X-ray.

    Foot drop is defined as the weakness of the foot and ankle dorsiflexion. Acute unilateral foot drop is a well-documented entity, whereas bilateral foot drop is rarely documented. Slowly progressing bilateral foot drop may occur with various metabolic causes, parasagittal intracranial pathologies, and cauda equina syndrome. Acute onset of bilateral foot drop due to disc herniation is extremely rare. Here we present two cases of acute bilateral foot drop due to disc herniation. The first patient was a 45-year-old man presented with acute bilateral foot drop, without any sign of the cauda equina syndrome. Lumbar magnetic resonance imaging of the patient revealed L4-5 disc herniation. To our knowledge, this is the first presented case of acute bilateral foot drop without any signs of cauda equina syndrome caused by L4-5 disc herniation. The second patient was a 50-year-old man who was also presented with acute bilateral foot drop, and had T12-L1 disc herniation with intradural extension. Also this is the first presented case of T12-L1 disc herniation with intradural extension causing acute bilateral foot drop. We performed emergent decompressive laminectomy to both of the patients and extrude disc materials were excised. Both of the patients were recovered with favorable outcome. PMID:25972945

    2014-02-01

    Leg stiffness is a predictor of athletic performance and injury and typically evaluated during bilateral hopping. The contribution of each limb to bilateral leg stiffness, however, is not well understood. This study investigated leg stiffness during unilateral and bilateral hopping to address the following research questions: (1) does the magnitude and variability of leg stiffness differ between dominant and non-dominant legs? (2) Does unilateral leg stiffness differ from bilateral leg stiffness? and (3) Is bilateral leg stiffness determined by unilateral leg stiffness? Thirty-two physically active males performed repeated hopping tests on a force platform for each of the three conditions: bilateral hopping, unilateral hopping on the dominant leg, and unilateral hopping on the non-dominant leg. Leg stiffness was estimated as the ratio of the peak vertical force and the maximum displacement using a simple 1-D mass-spring model. Neither the magnitude nor variability of leg stiffness differed between dominant and non-dominant limbs. Unilateral leg stiffness was 24% lower than bilateral stiffness and showed less variability between consecutive hops and subjects. Unilateral leg stiffness explained 76% of the variance in bilateral leg stiffness. We conclude that leg stiffness estimates during unilateral hopping are preferable for intervention studies because of their low variability. PMID:24290613

    2016-01-01

    Hyperhidrosis affects almost 3% of the population and is characterized by sweating that occurs in excess of that needed for normal thermoregulation. It can occur as a primary disease or secondary to underlying clinical conditions. Hyperhidrosis can stem from neurogenic sympathetic over activity involving normal eccrine glands. We report the interesting case of a 75-year-old male patient with a 6-month history of new onset secondary focal hyperhidrosis of buttocks, pelvis, and upper thighs. Each time his symptoms worsened he was found to have culture positive urine samples for Escherichia coli (E. coli). He underwent urological investigation and was found to have urethral strictures and cystitis. The hyperhidrosis improved each time his urinary tract infection (UTI) was treated with antibiotics and continued to remain stable with a course of prophylactic trimethoprim. We hypothesize that the patient's urethral strictures led to inhibition in voiding which in turn increased the susceptibility to UTIs. Accumulation of urine and increased bladder pressure in turn raised sympathetic nerve discharge leading to excessive sweating. We recommend that a urine dip form part of the routine assessment of patients presenting with new onset focal hyperhidrosis of pelvis, buttocks, and upper thighs. Timely urological referral should be made for all male patients with recurrent UTI. To the authors' knowledge, there have been no other reports of UTI-associated focal hyperhidrosis. PMID:27379188

    Ganglion cysts usually arise from the tissues around the facet joints. It is usually associated with degenerative cahanges in facet joints. Bilateral thoracic ganglion cysts are very rare and there is no previous case that located in bilateral intervertebral foramen compressing the L1 nerve root associated with severe radiculopathy. We report a 53 years old woman who presented with bilateral groin pain and severe numbness. Magnetic resonance imaging revealed bilateral cystic mass in the intervertebral foramen between 12th thoracal and 1st lumbar vertebrae. The cystic lesions were removed after bilateral exposure of Th12-L1 foramens. The result of hystopathology confirmed the diagnosis as ganglion cyst. The ganglion cyst may compromise lumbar dorsal ganglion when it located in the intervertebral foramen. The surgeon should keep this rare entity in their mind for differential diagnosis.

    Piriformis syndrome (PS) is an uncommon neuromuscular disorder caused by the piriformis muscle (PM) compressing the sciatic nerve (SN). The main symptom of PS is sciatica, which worsens with certain triggering conditions. Because the pathophysiology is poorly understood, there are no definite diagnostic and therapeutic choices for PS. This case report presents a young woman who mainly complained of bilateral leg weakness. Electromyography revealed bilateral sciatic neuropathy and magnetic resonance imaging confirmed structural lesions causing entrapment of the bilateral SNs. After a laborious diagnosis of bilateral PS, she underwent PM releasing surgery. Few PS cases present with bilateral symptoms and leg weakness. Therefore, in such cases, a high level of suspicion is necessary for accurate and prompt diagnosis and treatment. PMID:26798622

    Bilateral obturator nerve injury during pelvic surgery is an infrequent cause of lower limb paraparesis. We report the case of a 45-year-old woman with a large uterine leiomyoma who underwent simple total hysterectomy and bilateral salpingectomy. At 24 h after the surgery, the patient noticed loss of muscle strength when adducting both legs. She had no problem with other movements and no sensory or sphincter abnormalities. Neurological examination confirmed that there was loss of strength only in the adductor muscles, with preserved sensory function and reflexes, suggesting bilateral obturator nerve involvement. Pelvic MRI showed a small postsurgical haematoma in the Douglas recess, but far from the obturator nerves. 2 weeks later, electromyography showed positive sharp waves and low motor unit recruitment in the adductor magnus muscles, confirming acute, bilateral obturator nerve neuropathy. The few cases of bilateral obturator neuropathy that have been reported were mostly related to abdominopelvic interventions. PMID:26689250

    Bilateral clavicle fractures are uncommonly reported in the literature with the incidence being less than 0.5% of all the clavicle fractures. Bilateral clavicle fractures are caused either by high-energy transfer of compression forces across both shoulder girdles or by a direct trauma to one clavicle followed by that to the other clavicle. These fractures could be missed due to their association with more severe chest injuries or a more symptomatically displaced fracture on one side or due to inadequate chest radiographs. We report three cases of traumatic bilateral clavicle fractures with three modes of injuries in different age groups. All the fractures were treated conservatively with good functional outcomes without any sequelae. Bilateral clavicle fractures should be actively sought by every trauma team with proper clinical examination and chest radiographs including both shoulder joints in high-energy trauma cases or with bilateral shoulder compression injuries.
