Diagnosis of peptic ulcer in children: The past and present

The problem of diagnosis of peptic ulcer in children was analysed in a series of 50 consecutive cases. Atypical symptomatology occurred frequently and resulted in errors in diagnosis in six instances: perforated ulcer was misdiagnosed as appendicitis in five and bleeding ulcer was misdiagnosed as Meckels diverticulitis in one. Barium meal was the investigation employed in earlier years but had proven unsatisfactory, being incorrect in four out of 22 examinations. Fiberoptic endoscopy was introduced in recent years and having achieved correct diagnosis in 20 patients with no errors, has established itself as the choice of investigation.

Subglandular Urethral Fistula Following Circumcision: Repair by the Advancement Method

AbstractA post-circumcision urethral fistula is reported and a 1-staged repair is described.

Caseating regional lymphadenitis complicating BCG vaccination: a report of 6 cases.

Six infants had caseating regional lymphadenitis complicating BCG vaccination. There was a delayed onset and a lack of immediate vaccination complications. Three infants had frank abscesses. Additional affected nodes undetected clinically were found at operation in all cases. All lymph nodes contained tubercles, 3 showing acid-fast bacilli, 2 of which grew Mycobacterium bovis. Complete excision followed by antiuberculous chemotherapy produced satisfactory results.

Proximal end transverse colostomy in children. A method to avoid colostomy prolapse in Hirschsprung's disease.

A method of end transverse colostomy which avoids colostomy prolapse in Hirschsprungs disease is described.

Three successfully treated cases of nonamoebic liver abscess.

Three previously healthy children developed nonamoebic liver abscess. Diagnosis was aided by liver scan, ultrasound assessment, and computed tomography. A variety of surgical procedures were successful in achieving proper drainage, resection of chronic lesions, and resolution of associated cholangitis.

Acute Idiopathic Penile Edema: A Separate Clinical Entity?

Abstract An acute penile edematous condition seen primarily in children is reported. The condition has a benign, self-limiting course and is suspected to be a variant of acute idiopathic scrotal edema. The 3 children who have been seen with this condition in the last 4 years are discussed. We have not been able to trace a similar report of this entity in the literature.

Double purse string suture technique for loop colostomy prolapse in infants

ABSTRACT. Loop colostomy in infants is a common procedure, performed mainly for lower large bowel obstruction. However, prolapse of the colostomy is a frequent complication. A double purse string suture technique is advocated to fix the prolapse, and the results have been encouraging.

Advanced necrotizing enterocolitis: an indication for emergency separation of omphalopagus conjoined twins

Abstract Emergency separation was considered the treatment of choice when one omphalopagus twin developed advanced necrotizing enterocolitis (NEC). Twin B who developed advanced NEC died postoperatively but Twin A recovered satisfactorily.

A method of repair of thoracic cage defects after separation of thoraco-omphalopagus twins

Female thoraco-omphalopagus twins weighing 3,450 g were born by normal, spontaneous vaginal delivery. Though twin A was stable, twin B developed cardiorespiratory distress soon after delivery. Progressive respiratory failure led to separation at the age of 57 days. In order to repair the large thoracic cage defects a sheet of Teflon felt was tailored into two “tents”. Twin A who survived, had primary closure of the chest and abdomen after extensive skin mobilization. Twin B had a Silon chimney inserted in addition to the Teflon felt tent. Both were removed 20 days post-operatively because of infection. She died of respiratory failure 55 days after separation.
