Primary lymphedema of the penis: surgical correction by preputial unfurling.

Primary lymphedema of the penis (PLP) is a rare disease. We report a case in a 2-year-old, uncircumcised boy where the uninvolved inner preputial skin was unfurled to cover the penile shaft. The uninvolved inner preputial skin is often elongated, and provides a suture-free cover of sufficient length for the small penile shaft of pediatric patients.

Anomalous pancreaticobiliary union and chronic pancreatitis: rare presentation with biliary peritonitis.

Anomalous pancreaticobiliary union (APBU) has varied presentations. We report the case of a 12-year-old female who presented with biliary peritonitis due to a perforation of the common bile duct due to impaction of a pancreatic calculus at the duodenal papilla. She had a long common-biliary channel and pancreas divisum with chronic calcific pancreatitis involving the pancreatic head and neck. To our knowledge, this is the first such reported case in the literature.

Esophageal atresia with distal tracheoesophageal fistula associated with situs inversus.

The presence of situs inversus (SI) causes difficulty in the repair of esophageal atresia with tracheoesophageal fistula (EA/TEF). We report two cases: the first infant had situs SI abdominis with a right-sided aortic arch and the second had situs inversus totalis. To our knowledge, these are the first reported cases of repair of EA/TEF in a patient with SI.

Color flow Doppler sonography: a reliable alternative to voiding cystourethrogram in the diagnosis of vesicoureteral reflux in children.

OBJECTIVES: In children with urinary tract infection, the incidence of vesicoureteral reflux (VUR) is nearly 30% to 40%. The standard for the diagnosis of VUR is voiding cystourethrography (VCUG). This study assessed the role of color flow Doppler sonography (CFDS) in the diagnosis of VUR and ureteral jets. METHODS: CFDS imaging was performed in 36 patients aged 6 months to 13 years during a 4-year period. All patients underwent CFDS and VCUG within 24 to 48 hours, but the findings of the VCUG were not reported to the sonologist. The ultrasound examinations were done using a color Doppler real-time machine. Representative images of the bladder events were recorded with a multiformat camera and on VHS videotape. RESULTS: The duration of the Doppler signal varied from 0.4 to 7.5 seconds. In 31 (86.1%) of 36 patients, the results of CFDS correlated well with VCUG findings. There were three false-negative and two false-positive results in the present study. Six patients underwent reimplantation during the course of their treatment. CFDS was used as a follow-up modality at the end of 6 months, and the results correlated well with standard VCUG in 4 of these patients. In the remaining 2 patients, only CFDS was performed and correlation with VCUG was not possible. VCUG was considered the reference standard in assessing the sensitivity of CFDS. CONCLUSIONS: CFDS of the bladder during the filling and micturating phases is a reliable and sensitive modality for identifying VUR and demonstrating ureteral jets. CFDS nullifies the danger of exposure to ionizing radiation and avoids the unpleasant catheterization many of these children fear.

An unusual presentation in a patient with metachromatic leukodystrophy.

A 2-year-old child was admitted with bilateral bronchopneumonia. During convalescence he sustained sudden respiratory arrest for which he required ventilatory support. He had undergone cholecystectomy 1 month prior to the above episode. The pathological examination of the gall bladder mass had revealed the features of metachromatic leukodystrophy. Gastro-oesophageal reflux, which is associated with this neurological disorder, was suspected to be the cause of this sudden respiratory arrest and its presence was confirmed by barium swallow examination.

Primary gastric lymphoma in a boy.

Primary gastric lymphoma is an extremely uncommon entity in children, and diffuse large-cell-type lymphoma in this age group is still rarer. An 11-year-old boy with primary gastric lymphoma who responded to CHOP regime is reported.

Cystic mesenchymal hamartoma of the liver--a rare condition.

Cystic Mesenchymal Hamartoma of the liver is a rare benign tumour of infancy. Congenital cysts of the liver are of two main types: mesenchymal hamartoma and non parasitic cysts. The latter are encountered frequently while liver hamartomas are rare. The first reported case of mesenchymal hamartoma was that of Maresch in 1903. In 1956 Edmondson reviewed the literature and proposed the term "Mesenchymal Hamartoma" as a new clinical entity. In this paper we are discussing a rare case of cystic mesenchymal hamartoma of the liver, its clinical presentation, pathological characteristics, options of management and reviewing the relevant literature.

The 3-loop technique: a reliable technique for anterior pubic fixation in bladder exstrophy.

PURPOSE: In exstrophic anomalies the ultimate urological outcome largely depends on successful initial closure of the lower urinary tract and soft tissues. We believe that secure anterior pubic fixation is crucial for ensuring successful closure. After being dissatisfied with other methods of anterior pubic fixation we introduced the 3-loop method. The 3-loop technique and our experience with it are described. MATERIALS AND METHODS: In 2 years 7 consecutive cases of bladder exstrophy were closed using the 3-loop technique. Patient age at closure ranged from newborn to 9 years. RESULTS: In all 7 patients closure was successful and there was no cutting through of the wires, bony erosion, or erosion into the reconstructed bladder neck or urethra. The duration of postoperative traction was only 2 weeks. CONCLUSIONS: The 3-loop method is useful and reliable for secure anterior pubic fixation of the pubes in bladder exstrophy patients and it contributes positively to the ultimate urological outcome.

Hepatic hemangioendothelioma of infancy with congestive cardiac failure--report of a case.

A case of infantile hemangioendothelioma of the liver is reported in a 18 day-old male neonate. The neonate presented with CHF. He had hepatomegaly, but lacked the third component of the classical triad i.e. cutaneous hemangiomas. The S.A.F.P levels were raised to 920 ng/ml, though rise is rare in infantile hemangioendothelioma and led to the clinical diagnosis of hepatoblastoma. A left hepatic resection was performed, the histology showed a type I pattern of the tumor. This is known to be associated with a good prognosis. The baby is well post resection for a follow up period of six months.

Developmental anomalies associated with hypospadias.

Hundred and thirty patients with hypospadias were studied between 1983 and 1990, with an aim of analysing the associated anomalies in these patients. Urogenital anomalies were observed in 30% and extra-urogenital anomalies were noted in 16%. Undescended testis was the most frequently seen anomaly, having been noted in 6.9% of 130 cases. Vesico-ureteral reflux was present in 5.4% and inguinal hernia in 3.8%. The incidence of these anomalies increased in proportion to the severity of penile deformity. The present article emphasizes the need for systemic urological and endocrinal examination, especially in severe cases of hypospadias.

Chylothorax--a conservative approach (a case report).

Lymphatic blockage due to a non-specific inflammation probably of a filarial origin caused dilatation and ectasia of lymph channels at thoracic inlet of a child. Transudation of lymph through these channels led to chylothorax. The present case report highlights the significance of conservative approach towards this complex problem.

Rectal duplication.

Duplications of the alimentary tract are of a great rarity, particularly so in the rectum. Because of its rarity, the difficulty of making a correct diagnosis and of selection of proper approach for treatment, this entity bears a special significance. The present case report deals with a female newborn who presented with imperforate anus and a rectovestibular fistula and a mass prolapsing at the introitus. Complete excision of the mass was carried out through the perineal approach and the child then underwent, a PSARP for the correction of the rectal anomaly. Histology confirmed the mass to be a rectal duplication.
