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.

Papillomatosis of the gallbladder in metachromatic leukodystrophy

A 2-year-old boy who presented with a cystic gallbladder mass was found histologically to have metachromatic leukodystrophy. Diffuse hyperplasia of the gallbladder mucosa, multiple tendrillar fronds extending into the lumen, extensive papillomatosis, and the presence of large numbers of macrophages bearing metachromatic material confirmed the diagnosis. The child developed progressive degeneration of the central nervous system, refractory bronchopneumonia, and generalized muscular atrophy. A computed tomographic scan of the brain demonstrated hypodense areas of white matter suggestive of demyelination. This report describes the rare association of gallbladder papillomatosis with a storage disorder and reviews the relevant literature.

13 Pairs of ribs—A predictor of long gap atresia in tracheoesophageal fistula

BACKGROUND/PURPOSE Results of treatment of tracheoesophageal fistula (TEF) have improved over the years. However, long gap atresias continue to be a problem and require modification in the conventional operation. Preoperative diagnosis of a long gap atresia in a case of TEF is difficult, and often the defect is noted only at thoracotomy, thus necessitating multiple intraoperative changes in the position of the neonate. In the past 5 years the authors have treated 61 cases of TEF. Of these, 12 had a long gap atresia. Nine of these 12 patients had 13 pairs of ribs. None of the patients with a short gap atresia had 13 pairs of ribs. Hence, the presence of 13 pairs of ribs is a good indicator of long gap atresia. In a child who has TEF with 13 pairs of ribs, suitable modifications in operative procedure can be planned. The report also discusses the possible embryological basis of this association.

Intestinal atresia: an end-to-end linear anastomotic technique

Abstract. In a series of 19 neonates with small-bowel atresia, 16 were treated by end-to-end linear anastomosis (ELA) without resection and 3 by resection anastomosis (RA). Seven atresias were jejunal, 11 were ileal, and 1␣jejunoileal; 3 cases were type II, 12 type IIIa, 3 type IIIb, and 1 type IV. There were 4 deaths, 1 after ELA and 3 after RA. The overall mortality decreased from 68 to 20.80% and for linear anastamosis to 6.25% presumably, because the intestinal contents are propelled along the lumen in a linear fashion and not at an angle as in end-to-back anastamosis, avoiding shearing of the suture line. The additional plicating sutures reduce the radius and increase the propelling force. We recommend this technique because it is based on sound principles of physics and preserves the entire available length of intestine.

Embryogenesis of bladder exstrophy: A new hypothesis

Aims and Objective: To postulate a hypothesis to explain the embryogenesis of exstrophy bladder based on our clinical observations. Materials and Methods: In 27 cases of exstrophy, we measured the distance between the lowermost inguinal skin crease to the root of the penis (clitoris) (B) and the distance between the penis (clitoris) and the scrotum (labia majora) (C). These were compared with age, height and XP distance (distance between xiphisternum and symphysis pubis) matched control group of normal children. The distance between the lowermost inguinal skin crease and the penis (clitoris) (A) was measured in control group. Results: The observation was A = B + C. This implies that in exstrophy bladder, the position of the penis (clitoris) has moved cephalad from the lower border of A to the junction of B and C. Conclusion: Based on the observations, we postulate that abnormal origin of genital tubercle may be the cause of exstrophy bladder. The abnormal origin of primordia of the genital tubercle in more cephalad direction than normal causes wedge effect, which will interfere with the medial migration of the mesoderm as well as the midline approximation of mesodermal structures in the lower abdominal wall, thereby resulting in the exstrophy of bladder.

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.

Double meningomyelocele: Embryogenesis

A new technique for repair of exstrophy-epispadias complex

Abstract. We report a new method of repair of exstrophy-epispadias complex (EEC) at a second stage by using flaps from the skin between the penis and scrotum (the clitoris and labia majora in females) used in seven patients. The non-pigmented skin between the penis and scrotum in males or a band of skin between the clitoris and labia majora in female is mobilized in two flaps, which are rotated superiorly. Five patients were treated primarily by this method and two patients at the time of secondary reconstruction. There were six boys and one girl. Two patients were post-pubertal, one male and one female. Follow-up (6–12 months) revealed good cosmetic and functional results. If EEC is repaired in a single stage, the entire pelvic diaphragm is visualized from inside and the sphincters can be reconstructed around the bladder neck. This procedure gives better exposure of attachments of the corporal bodies to the pubic rami, allowing easier mobilization. The bulbospongiosus muscle can be reconstructed. A normal penoscrotal relation is achieved in male patients. The root of the scrotum, which is splayed out and wide, narrows. Rotation of the flaps superiorly normalizes the symphyseal area. In female patients the appearance of the mons pubis is satisfactory. In post-pubertal children the pubic hair distribution appears normal.

An unusual cause of stridor: retropharyngeal cold abscess.

Abstract A 15-month-old female presented with a large swelling on the left lateral aspect of the neck and respiratory distress, and stridor due to incomplete obstruction of the upper airway. A lateral X-ray film and computerized tomography scan of the cervical spine showed a retropharyngeal abscess without vertebral involvement. Aspiration and contrast revealed it to be a bilobed tubercular abscess. Planned external drainage was done after 10 days under anti-tubercular drugs.

Spontaneous gastroduodenal disruption in neonate

Abstract A 2-day-old female presented with massive abdominal distention and respiratory distress. An erect abdominal X-ray film revealed a pneumoperitoneum of saddlebag configuration. The patient was resuscitated and a peritoneal drain was put through the right flank. Air and bile drained, and the respiratory distress was relieved. After the patient had stabilised haemodynamically, an exploratory laparotomy revealed a total gastroduodenal disruption. A gastrojejunostomy was done; the pyloric and duodenal ends were closed in two layers. The postoperative course was uneventful. We report this case for its unusual and rare presentation.
