Role of color Doppler ultrasound in the diagnosis of nonpalpable testes

Purpose Color Doppler ultrasound has been used for the diagnosis of torsion of testes. The purpose of this study was to evaluate the sensitivity of this noninvasive tool in detecting impalpable testes.Patients and methods Twenty-five children with nonpalpable testes were treated at the Department of Pediatric Surgery, Institute of Medical Science, Banaras, between 2007 and 2009. Color Doppler ultrasound was used for detecting the position, size, and vascularity of nonpalpable testes. These patients were subsequently revaluated by laparoscopy.Results Out of 25 cases, 15 cases were unilateral and 10 cases were bilateral (a total of 35 nonpalpable testes). The color Doppler ultrasound study successfully localized 30 of the 35 nonpalpable testes, which were confirmed by subsequent laparoscopic examination. The sensitivity of color Doppler in locating testes was 85.71% (95% confidence interval = 0.64–0.97).Conclusion Color Doppler ultrasound is an effective noninvasive method for the initial diagnosis of impalpable testes and for planning its subsequent management.Keywords: color Doppler ultrasound, laparoscopy, nonpalpable teste

Minimizing the postoperative complications of severe hypospadias using a simple technique

Background The aim of this study was to decrease complication rates in proximal hypospadias surgery.Methods A simple method of stenting using a polypropylene stent has been developed for the most severe form of hypospadias during the period from January 2008 to January 2011 in the Department of Pediatric Surgery. The total number of patients was 46. The patients were classified into group 1 (n= 23), in which a polypropylene stent was used, and group 2 (n= 23), in which a polypropylene stent was not used.Results In group 1, complications occurred in three patients (13.04%), whereas in group 2 it occurred in 12 patients (52.2%). The difference in the total number of complications between groups was highly significant (P < 0.001). In group 1, no patient needed redo surgery, and in group 2 four patients (17.39%) needed redo surgery (P < 0.05). All other patients responded to repeated dilatation in the follow-up.Conclusion Although the sample size was small, this simple modification can decrease the complication rate significantly in the most severe form of hypospadias. Keywords: polypropylene stent, proximal hypospadias, surgical complications, urethroplast

Jejunal atresia presenting with mesenteric cyst in a neonate: a case report

Jejunoileal atresia is a congenital anomaly that is characterized clinically by bilious vomiting and abdominal distension. It has been associated with various congenital anomalies but its association with mesenteric cyst has only been reported sporadically. As this is a very rare entity, it is being reported with a brief review of literature

Pediatric carcinoma of rectum - Varanasi experience

Background : Primary gastrointestinal system malignancies constitute approximately 2% of pediatric neoplasm and of these; colorectal carcinoma is the second most common malignancy. This is one of the rarer diseases in children. Aim : We reviewed our records to study the clinical features, outcome and the follow-up of this condition with evaluation of the prognostic factors. Settings and Design: Tertiary care Pediatric Surgery centre. Retrospective study. Materials and Methods : The data of all patients with diagnosis of colorectal carcinoma from January 1986 to January 2006 were reviewed. The confirmation of the diagnosis was by biopsy from the lesion. The age, sex, family history, clinical features, response to the treatment and follow-up were studied. Results : There were four male patients. All had bleeding per rectum as the presenting complaint. Three patients had advanced disease at presentation. All the patients had signet cell adenocarcinoma. The two patients expired and one was lost to follow-up. One patient is alive after one year of follow up and is receiving treatment. Conclusion : Colorectal cancer in children though rare can be a reality, hence any children presenting with pain in abdomen along with doubtful history of constipation and rectal bleeding should be examined carefully with special emphasis on digital rectal examination

Double coin in esophagus at same location and same alignment - a rare occurrence: a case report

Coin is the most common foreign body swallowed by pediatric age group. The multiple coin swallowing is extremely rare and very few cases had been reported in English literature. Most of them were present at different site and had different alignment in the esophagus. The location of the coin (trachea vs. esophagus) is commonly determined by the alignment of the coin on radiographic studies. A 4-year-girl was presented to us with history of coin ingestions one day back without any respiratory distress. On radiological study there was suspicion of two coins on same location and alignment. The diagnosis was confirmed after removal. The both coin was removed successfully by esophagoscopy. Unexpected second foreign bodies in pediatric esophageal coin ingestions are rare and it is mandatory to do post operative radiography after removal to exclude duplex coin or tracheal coin. We are presenting this case because of its rarity, difficulty in diagnosis especially when proper history is not available

Polypyrrole-Fe2O3 nanohybrid materials for electrochemical storage

We report on the synthesis and electrochemical characterization of nanohybrid polypyrrole (PPy) (PPy/Fe2O3) materials for electrochemical storage applications. We have shown that the incorporation of nanoparticles inside the PPy notably increases the charge storage capability in comparison to the “pure” conducting polymer. Incorporation of large anions, i.e., paratoluenesulfonate, allows a further improvement in the capacity. These charge storage modifications have been attributed to the morphology of the composite in which the particle sizes and the specific surface area are modified with the incorporation of nanoparticles. High capacity and stability have been obtained in PC/NEt4BF4 (at 20 mV/s), i.e., 47 mAh/g, with only a 3% charge loss after one thousand cyles. The kinetics of charge–discharge is also improved by the hybrid nanocomposite morphology modifications, which increase the rate of insertion–expulsion of counter anions in the bulk of the film. A room temperature ionic liquid such as imidazolium trifluoromethanesulfonimide seems to be a promising electrolyte because it further increases the capacity up to 53 mAh/g with a high stability during charge–discharge processes

Neonatal scrotal wall necrotizing fasciitis (Fournier gangrene): a case report

<p>Abstract</p> <p>Introduction</p> <p>Necrotizing fasciitis in neonates is rare and is associated with almost 50% mortality. Although more than 80 cases of neonates (under one month of age) with necrotizing fasciitis have been reported in the literature, only six of them are identified as originating in the scrotum.</p> <p>Case presentation</p> <p>We report the case of a four-week-old, full-term, otherwise-healthy Caucasian baby boy who presented with an ulcerating lesion of his scrotal wall. His scrotum was explored because of a provisional diagnosis of missed torsion of the testis. He was found to have necrotizing fasciitis of the scrotum. We were able to preserve the testis and excise the necrotic tissue, and with intravenous antibiotics there was a successful outcome.</p> <p>Conclusions</p> <p>Fournier gangrene is rarely considered as part of the differential diagnosis in the clinical management of the acute scrotum. However, all doctors who care for small babies must be aware of this serious condition and, if it is suspected, should not hesitate in referring the babies to a specialist pediatric surgical center immediately.</p
