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.

Splenectomy in children in Hong Kong.

A review of the hospital course of 82 splenectomies in children performed in the past 15 years has been carried out. Three indications have been identified: therapeutic, diagnostic, and traumatic. Thalassemia was identified as the commonest indication. Comparisons of the spleens removed showed that those from thalassaemia patients were the biggest, while those removed for idiopathic thrombocytopenic purpura (ITP), lymphoma staging, and trauma, were small. Twenty-eight per cent of patients had accessory spleens. Intrathoracic complications were frequent in the traumatic cases, whereas wound complications were commoner after splenectomies carried out for haematological reasons. No gallstones were detected. The platelet response to the various indications was studied and compared. There were two postoperative deaths.

Ultrasound-guided hydrostatic reduction of childhood intussusception: technique and demonstration.

The authors review the technique of ultrasound-guided hydrostatic reduction of childhood intussusception and illustrate, in real-time fashion, the treatment of three cases with this technique. Two cases of successful reduction of ileocolic intussusception are demonstrated. The third case is an example of the complex fronded appearance of ileo-ileocolic intussusception and failed reduction. This technique is recommended as an alternative method for the treatment of childhood intussusception, as it does not involve ionizing radiation and is a simple and safe procedure.

Wilms' tumor with intracardiac extension: chemotherapy before surgery.

The article describes two Chinese boys ages 2 and 3 years with unilateral Wilms' tumors complicated by intracaval and intracardiac extension. In contrast to the previously recommended treatment with surgery followed by chemotherapy and radiation therapy, the children were managed primarily with combination chemotherapy before definitive operation. Reduction of tumor size on serial imaging was documented, and no viable tumor cells were found when the involved kidney and right atrium were explored. Both patients remained alive without evidence of disease more than 5 years after initial diagnosis. A literature search revealed case reports and retrospective analyses of 70 patients with Wilms' tumors and intracardiac involvement, and a tendency toward preoperative chemotherapy with or without the addition of radiation therapy was observed. The overall outcome of this group of patients parallels the outcome of those without intracardiac extension by histology and stage. Wilms' tumor presenting with extension into the inferior vena cava and right atrium is thus rare and renders the affected child with additional cardiovascular complications and operative risks. As a result of the uncommon occurrence, a consensus on management based on prospective study would be difficult. The present report and the literature are supportive of the use of preoperative chemotherapy in the initial management of advanced Wilms' tumor extending into the right atrium.

Liver transplantation--perspective from Hong Kong.

BACKGROUND/AIMS: We report our experience of 27 orthotopic liver transplantations in 26 patients performed at Queen Mary Hospital, Hong Kong during the period of October 1991 to October 1995. PATIENTS AND METHODS: There were 19 adults and 7 pediatric patients with a mean age of 29 years (range 8 months to 62 years). The underlying liver diseases of the 26 patients were biliary atresia (n = 6), Alagille syndrome (n = 1), primary biliary cirrhosis (n = 2) cryptogenic cirrhosis (n = 2), alcoholic cirrhosis (n = 5), Wilson's disease (n = 1), fulminant hepatic failure (n = 3), polycystic liver (n = 2), secondary biliary cirrhosis (n = 1), HBV cirrhosis (n = 2) and autoimmune hepatitis with hepatocellular carcinoma (n = 1). The pathology leading to re-transplantation in a pediatric patient was post-transplant hepatitis of unknown etiology. The liver grafts were obtained from 19 brainstem dead and 8 living donors. The pediatric patient requiring re-transplantation received a left lateral segment graft from her mother. Two adults received left lobe grafts from their family members. RESULTS: The overall graft survival is 88% and patient survival is 92%. There were only 2 deaths: one patient developed primary graft nonfunction and died from intracerebral bleeding 39 days after transplantation and the other died from graft rejection resistant to salvage by steroid pulse and OKT3. The other patients are well with functioning grafts. CONCLUSIONS: We hope that the current success rate can convince people in our locality in cadaveric organ donation so that living donors do not run the risk of dying from the operation, although the risk is estimated to be very small.
