Outcome of endoscopic treatment for vesicoureteral reflux in children using polydimethylsiloxane

PURPOSE: We reviewed the outcome of subureteral injection of polydimethylsiloxane as a bulking agent for endoscopic treatment for vesicoureteral reflux in patients younger than 12 years. MATERIALS AND METHODS: A total of 40 children (59 ureters) with primary grades II to IV vesicoureteral reflux were treated with a single subureteral injection from 1997 to 2001 and followed an average of 26 months (range 4 to 45). Results in 38 patients (55 ureteral units) were available for review. Each child underwent preoperative voiding cystourethrography, renal ultrasound, dimercapto-succinic acid scan and urine culture. Treatment was done on an outpatient basis. With the patient general anesthesia polydimethylsiloxane implant was injected transurethrally below the ureteral opening of the affected renal unit. Renal ultrasound at 1 week and voiding cystourethrography at 2 months were done to rule out obstruction at the injection site and/or persistent reflux, respectively. Cure was defined as absent vesicoureteral reflux on voiding cystourethrography 2 months after injection. RESULTS: After a single injection polydimethylsiloxane cured vesicoureteral reflux in 45 ureteral units (81.8%), while in 5 (9.1%) the condition was improved. The remaining 5 ureteral units (9.1%) showed no change in reflux grade. In 1 patient (1.9%) with unilateral grade IV vesicoureteral reflux contralateral reflux developed. None of the cured patients had recurrent reflux during followup. In 1 patient ureteral obstruction was successfully treated with ureteral reimplantation. CONCLUSIONS: Endoscopic subureteral injection of polydimethylsiloxane implant in children with primary grades II to IV vesicoureteral reflux appears to be an effective, safe and minimally invasive technique.     

15 Years in surgical management of pulmonary hydatidosis.

OBJECTIVES: Echinococcosis remains an endemic surgical problem in countries where sheep and cattle raising is carried out, particularly in many Mediterranean countries. This study aims to evaluate the management of different presentations of pulmonary hydatidosis and their outcome over 15 years. DESIGN: Retrospective study.Setting: Thoracic surgical department, Chest Diseases Hospital, Kuwait. PATIENTS: Sixty patients operated upon for hydatid disease were evaluated pre- and post- operatively; 35 males, 25 females with a mean age of 28.4 years. Most patients were investigated by laboratory, serological and radiological studies. Different surgical techniques were used to remove the hydatid cyst from the lung. RESULTS: The most common presenting symptoms were cough (41 patients), and 12 patients were asymptomatic. Chest X-ray showed a rounded shadow in 42 patients; 19 cases were of vigorous size >10 cm. Thoracotomy was done in 57 patients; two chest wall cases were managed by minimal skin incision and enucleation, one hydatid cyst of the heart was approached through a median sternotomy. The mean hospital stay was 9 days. Postoperative complications occurred in 9 patients; prolonged air leak in 4 patients, pleural effusion in 3, pneumothorax, and wound infection in one patient each. One patient (65 years old) died on the 6th post-operative day most probably from pulmonary embolism. In a follow-up period of 2-15 years, 4 recurrences have been noted. CONCLUSION: Surgical excision of pulmonary hydatidosis with maximum preservation of the lung parenchyma is the main stay of treatment.     

Impact of Calcium and Two Doses of Vitamin D on Bone Metabolism in the Elderly: A Randomized Controlled Trial

The optimal dose of vitamin D to optimize bone metabolism in the elderly is unclear. We tested the hypothesis that vitamin D, at a dose higher than recommended by the Institute of Medicine (IOM), has a beneficial effect on bone remodeling and mass. In this double‐blind trial we randomized 257 overweight elderly subjects to receive 1000 mg of elemental calcium citrate/day, and the daily equivalent of 3750 IU/day or 600 IU/day of vitamin D3 for 1 year. The subjects’ mean age was 71 ± 4 years, body mass index 30 ± 4 kg/m², 55% were women, and 222 completed the 12‐month follow‐up. Mean serum 25 hydroxyvitamin D (25OHD) was 20 ng/mL, and rose to 26 ng/mL in the low‐dose arm, and 36 ng/mL in the high‐dose arm, at 1 year (p < 0.05). Plasma parathyroid hormone, osteocalcin, and C‐terminal telopeptide (Cross Laps) levels decreased significantly by 20% to 22% in both arms, but there were no differences between the two groups for any variable, at 6 or 12 months, with the exception of serum calcitriol, which was higher in the high‐dose group at 12 months. Bone mineral density (BMD) increased significantly at the total hip and lumbar spine, but not the femoral neck, in both study arms, whereas subtotal body BMD increased in the high‐dose group only, at 1 year. However, there were no significant differences in percent change BMD between the two study arms at any skeletal site. Subjects with serum 25OHD <20 ng/mL and PTH level >76 pg/mL showed a trend for higher BMD increments at all skeletal sites, in the high‐dose group, that reached significance at the hip. Adverse events were comparable in the two study arms. This controlled trial shows little additional benefit in vitamin D supplementation at a dose exceeding the IOM recommendation of 600 IU/day on BMD and bone markers, in overweight elderly individuals. © 2017 American Society for Bone and Mineral Research.     

Skin-Sparing Mastectomy with Immediate Breast Reconstruction by a New Modification of Extended Latissimus Dorsi Myocutaneous Flap

Background  The introduction of skin-sparing mastectomy has revolutionized both breast cancer surgery and breast reconstruction. Latissimus dorsi myocutaneous flap is a versatile flap that is gaining renewed popularity with the development of flap modifications and the continued recognition of its reliability and safety. We report our results with a new modification of the extended latissimus dorsi flap after skin-sparing mastectomy for breast cancer. Methods  From January 2002 to January 2006, 140 patients of breast carcinoma had unilateral skin-sparing mastectomy and immediate breast reconstruction. A total of 132 cases of invasive duct carcinoma and eight cases of invasive lobular carcinoma are included. Age ranged from 27 to 53 (median, 40.5) years. Tumor stage was stage I in 22 cases, stage II in 100 cases, and stage III in 18 cases. We performed a new modification to the standard extended latissimus dorsi flap, which allowed us to obtain enough autologous tissue to reconstruct the relatively large breast of the Egyptian women without implant. The postoperative aesthetic results and donor side morbidity, including contour deformity and scaring, were examined. Results  We applied both an objective and subjective aesthetic result monitoring. Aesthetic grading results of breast reconstruction were excellent in 85, good in 42, fair in ten and poor in three cases. Both flap and donor site complications were minor. Patients were followed for a median of 32.4 (range, 12-48) months. During this period of follow-up, no episode of local or distant failure was observed. Conclusions  Skin-sparing mastectomy with immediate breast reconstruction using our new modification of extended latissimus dorsi flap allows single-stage, totally autologous reconstruction with satisfactory aesthetic results and low morbidity.     

The role of cancellous screw with tension band fixation in the treatment of displaced olecranon fractures,a comparative study

Introduction  Fractures of the olecranon are among the most common injuries involving the upper extremity and require operative intervention if displaced. The most commonly used method of fixation for this type of fracture is the AO tension band wiring, although the results of this technique have been generally good, still problems have occurred, including loss of fixation, nonunion, and high re-operation rate for hardware removal. Aim of the study  To compare the results of treatment of displaced fractures of the olecranon using AO tension band wiring versus intramedullary screw with tension band. Materials and methods  In a prospective study, 30 patients with transverse or oblique olecranon fractures, were randomly divided into two equal groups, one group treated using AO tension band wiring the other group using an intramedullary cancellous screw plus tension band. Results  In the screw plus tension band group, 11 (73.3%) patients had excellent results, four (26.7%) had good results and none had fair or poor results, only one(6.6%) patient required second operation for removal of prominent hardware. In the AO tension band group, six (40%) patients had excellent results, five (33.3%) had good, three (20%) had fair and one (6.7%) patient had poor result, and eight patients (53.3%) required second operation for removal of prominent hardware. Conclusion  Using an intramedullary screw combined with tension band in treatment of displaced transverse and oblique olecranon fractures gives better clinical results and has much less re-operation rate for removal of hardware when compared to AO tension band wire fixation, avoiding costs, work time loss and possible complications from hardware removal.     

Autologous fascial sling vs polypropylene tape at short-term followup: a prospective randomized study

PURPOSE: The incidence of urinary incontinence in women of childbearing age is about 30%. Around half have stress incontinence. Many treatment modalities have been elucidated to treat stress incontinence, and among the most popular are rectus fascia sling and tension-free vaginal tape (TVT). The introduction of TVT to the urological armamentarium put a multiplicity of synthetic materials into use in the correction of stress urinary incontinence. A comparison of the impact of these 2 commonly used techniques is needed. MATERIALS AND METHODS: A total of 53 female patients older than 21 years (mean age 45.09) were randomized, using closed envelopes, to undergo TVT or rectus fascia sling. Randomization was performed after patients received spinal anesthesia. One surgeon performed the 2 types of treatment. Associated grade 2 cystocele was simultaneously corrected. Patients with bladder or urethral pathology, as well as those with cystocele greater than grade 2, were excluded from analysis. RESULTS: All 53 patients completed 6 months of followup and all had stress urinary incontinence. There were 15 patients who underwent sling surgery and 17 who underwent TVT who had concomitant grade 1 or 2 cystocele. No statistically significant difference was found between the 2 groups at baseline. Cure was accomplished in 23 of 25 (92%) with sling and in 26 of 28 (92.9%) with TVT at first followup visit (1 week). There were 7 patients who needed at least 1 extra week of catheterization in the sling group and 3 in the TVT group. No significant difference was detected in terms of post-void residual urine, symptom score, and filling and voiding parameters. At 6 months 1 patient had de novo detrusor overactivity and 7 had wound pain. Compared to those with TVT, 2 cases of sling were considered treatment failures, none had de novo overactivity and 2 had wound pain. None of the patients had symptoms suggestive of urethral erosion. CONCLUSIONS: Rectus fascia sling and TVT seem to be equally effective regarding primary outcome measure (ie cure of stress incontinence). Symptom score related to incontinence surgery as well as simultaneous correction of cystocele are comparable in the 2 groups. Fascial sling is a longer treatment process yet it is more economical. Longer followup is vital before rigorous conclusions can be drawn.     

Splenogonadal fusion: case presentation and literature review

Splenogonadal fusion is a rare congenital anomaly in which there is fusion of the spleen and the gonad or mesonephric derivatives. To date, approximately 150 cases have been reported since the condition was first described by Bostroem in 1883 (Bostroem E. Demonstration eines Praparates von Verwachsung der Milz mit dem lenken Hoden. Gesellschaft deutscher Naturforscher und Aerzte, Verhandlungen der 56 Versammlung, Freiburg; 1883. p. 149). Very few cases have been diagnosed preoperatively, and many cases presenting as a testicular swelling underwent an unnecessary orchiectomy with the suspicion of a testicular neoplasm. A case is presented and the related literature is reviewed.     

Pelvic ramus fractures in the elderly: 50 patients studied with MRI

Background Whilst it is well known that fractures of the pelvic rami in the elderly are frequently associated with posterior ring injuries, the extent of this second injury is less well known. We evaluated this question by MRI scanning a group of elderly patients presenting at our unit with pelvic rami fractures.

Patients and methods We investigated 50 consecutive elderly patients (45 women) with fractures of the pelvic rami using an MRI scan of the pelvis in order to assess the competency of the pelvic ring.

Results On MRI, 45 (95% CI 42-48) patients had a sacral fracture. At 5-month follow-up, 39 (of 41 reviewed) still complained of posterior sacral tenderness.

Interpretation Pelvic rami fractures in the elderly are nearly always associated with posterior ring injuries. This probably explains why these patients take longer to rehabilitate than might be expected if only the anterior injury is considered, and it also explains why they experience long-term back pain.     

Home glucometer monitoring markedly improves diagnosis of post renal transplant diabetes mellitus in renal transplant recipients

BACKGROUND: Definitions of de novo posttransplant diabetes mellitus (PTDM) have varied widely in the renal transplant literature, and most have not used the American Diabetes Association (ADA) definition of diabetes (fasting plasma glucose [FPG] > or = 126 mg/dl on two occasions, or a casual plasma glucose level >200 mg/dl). Most patients are monitored for PTDM by 12-hour FPG levels drawn for clinic visits. In contrast, we describe the diagnosis of PTDM by home glucometer monitoring METHODS: We screened 89 consecutive nondiabetic renal transplant recipients for PTDM by ADA criteria and home glucometer monitoring during the first 3 months posttransplant RESULTS: Of 23 patients with impaired fasting glucose levels of 111-126 mg/dl, 14 (61%) met ADA criteria for diabetes mellitus of based on home glucometer monitoring. The incidence of de novo PTDM was 31% during this period. Predictors of PTDM in a Cox proportional hazards model were race and acute rejection, with a trend towards BMI. Clinic visit FPG levels did not differ between PTDM and non-PTDM patients. All diagnoses were made based on prelunch or supper FPG >200 mg/dl. CONCLUSIONS: Overnight FPG are inadequate for diagnosis of PTDM. All renal transplant recipients with impaired FPG should, at minimum, have home FPG testing.
