Detection of caustic oesophageal injury with technetium 99m-labelled sucralfate.
BACKGROUND/PURPOSE: Radiolabelled sucralfate has been used to show the extent and severity of reflux oesophagitis, peptic ulceration, and inflammatory bowel disease. Endoscopy under general anaesthetic has been the preferred method to assess the injury after caustic ingestion. The aim of this study was to assess whether sucralfate has an affinity for the chemically injured oesophageal mucosa and, if so, to assess the accuracy of radiolabeled sucralfate as an indicator of presence and extent of oesophageal injury. METHODS: A prospective study was conducted of 22 patients with mean age of 30 months (range, 13 to 90) admitted consecutively with a history of caustic ingestion between January 1998 and January 2000. A sucralfate-labelled scan followed by endoscopic assessment of upper gastrointestinal tract with documentation of extent and grade of injury was performed in all patients within 24 hours of admission except the first 6 who underwent scan after the endoscopy. The sucralfate was labelled by the direct stannous reduction method. Oesophageal transit was studied by recording 120 images (64 x 64 matrix size) at 1 image per second while the child swallowed 5 mL of labelled sucralfate containing 2 to 3 MBq Technetium 99m. Retention of radiolabelled oesophageal activity was considered abnormal. RESULTS: The caustic substances ingested were household cleaners in 18, potassium permanganate in 3, and pool chlorine in 1. There were 11 scans that showed residual activity in the oesophagus, which correlated exactly with endoscopic findings. The other 11 patients had normal oesophageal mucosa, but 2 were found to be falsely positive on scanning. In 2 cases repeat sucralfate scan results correlated well with the healing process assessed endoscopically. CONCLUSIONS: The results indicate that technetium 99m sucralfate swallow is an accurate technique for assessing oesophageal injury after ingestion of caustic substances. In addition, it may be used to document healing.

The surgical management of cricopharyngeal achalasia in children.
OBJECTIVE: The objective of this study was to evaluate the clinical presentation of children with cricopharyngeal achalasia and to document the diagnostic process followed and evaluate the immediate and long-term results of those children treated with a cricopharyngeal myotomy. METHODS: Five children who underwent cricopharyngeal myotomies since 1976 were identified and the hospital records were reviewed in detail. Four patients were followed up to establish the long-term results of surgery. RESULTS: The age of initial presentation ranged from birth to 6 months with a universal delay in establishing the diagnosis ranging from 11 to 138 months. Two children had pre- and post-operative manometry of the upper esophageal sphincter. Post-operative upper esophageal sphincter pressures were reduced to 29 and 47% in relation to pre-operative values. Nissen fundoplications were performed in two patients to control documented gastro esophageal reflux. No post-operative complications were noted and complete symptomatic relief was obtained in all children. The long-term follow up was 2, 10, 12 and 14 years with all children remaining free of symptoms. CONCLUSION: Cricopharyngeal achalasia is an important but relatively seldom diagnosed cause of dysphagia in children. The diagnosis is almost always delayed because the condition is not widely recognised amongst physicians. If the diagnosis and effective treatment is delayed significant morbidity or even mortality, mainly due to pulmonary aspiration, may result. Cricopharyngeal myotomy is a safe and effective operation with excellent results. Symptomatic relief is immediate and complete with no long-term recurrence documented in this series.

Cooling the burn wound: evaluation of different modalites.
A study was undertaken to investigate the cooling and healing effect of different modalities: Melaleuca Alternifolia Hydrogel (Levtrade International (Pty) Ltd.) was compared with tap water as a coolant following application onto a fresh deep partial thickness hot water burn in a porcine model. Four identical circular scalds were created on the backs of 10 pigs. One wound was not treated and served as a control. The other 3 wounds were either cooled with tap water (15 degrees C) or had Melaleuca Hydrogel dressing applied immediately, or after a 30 min delay. Intradermal temperatures were monitored in all wounds: preburn, during the burn and at regular intervals for 1 h. The wounds were biopsied for histological assessment. These samples were repeated at 24 h and 3 weeks. The mean decrease in final temperature at 1 h was in comparison to the preburn temperature; control +0.44 degrees C (i.e. a temperature increase); water -7.82 degrees C; Melaleuca Hydrogel -3.87 degrees C; Melaleuca Hydrogel after 30 min delay -2.67 degrees C. Clinical and histological assessment at 21 days indicated more rapid healing in both the Melaleuca Hydrogel and water-cooled burns compared with the untreated controls. Effective cooling of the burn wound and an increased rate of wound healing was achieved by both repeated tap water compresses and by immediate or delayed application of Melaleuca Hydrogel. Cooling is an effective means to reduce tissue damage and increase wound healing.

Liver transplantation in children--the Red Cross War Memorial Children's Hospital experience.
Liver transplantation for infants and children has been available in South Africa for more than a decade. Current concerns have shifted from an initial target of early post-transplant survival to quality of life in the long term. Since 1985, 175 infants and children have been assessed, with 104 accepted for transplantation. Fifty have had orthotopic liver transplants (OLTx), 48 (3 retransplants) in Cape Town and 2 abroad. Biliary atresia was the most frequent diagnosis (52%) followed by acute liver failure (ALF) (16%). Waiting list mortality has remained high (15%), particularly for the ALF group (50%). Thirty-four patients survive 1 month--14 years post-transplant. Early post OLTx mortality was low (7%) but late morbidity and mortality (23%) were mainly due to viral infection: de novo hepatitis B (5 patients, 2 deaths), EBV-related post-transplantation lymphoproliferative disease (PTLPD) (6 patients, 4 deaths) and CMV disease (9 patients, 4 deaths). Tuberculosis prophylaxis, required in 6 cases, resulted in major morbidity in 1. Hypertension requiring medication along with some compromise of renal function has been present in all but 2 patients. However, all those of school-going age (20) attend school normally and remain in good health and only 3 of the survivors have abnormal liver function tests. Successful liver transplantation is possible in a developing country with limited resources. Scarcity of virus-free donors (HBV and HIV) leading to waiting list mortality and infrequent retransplantation along with long-term consequences of immunosuppression (infection, lymphoma and renal toxicity) remain problems.

Inhalation burns in children.
Survival from serious burns in children has improved substantially in recent years. Mortality is predominantly determined by the total body surface area burned and the often unrecognised inhalation injury. A retrospective review of 4,451 consecutive children with thermal injuries over a 10-year period was undertaken to determine the incidence, clinical presentation, and pathology of inhalation injury and its contribution to morbidity and mortality. Inhalation burns were diagnosed clinically and confirmed endoscopically and post-mortem in 97 (2.2%) children; 77 sustained fire burns (mean age 4 years) and 20 hot-water burns (mean age 18 months). The Moylan classification stratified them into upper-airway burns in 59 children, major-airway burns in 29, and parenchymal burns in 44. Major-airway burns were always seen in conjunction with either upper-airway or parenchymal injury. Stridor and acute progressive respiratory distress were the two main symptoms, the onset of which was occasionally delayed for up to 72 h. Endoscopy was most helpful in confirming the diagnosis and determining airway management. Endotracheal intubation was needed in more than 50% of children, usually for less than 5 days, and was converted to tracheostomy in only 6. Persistent laryngeal and tracheal damage was identified in 4. Secondary pneumonia occurred in 41.5% of children with fire burns and 55% with hot-water burns. Extensive surface burns, parenchymal injury, and secondary pneumonia all contributed to the significant mortality. Post-mortem findings corroborated clinical and endoscopic evidence. This study suggests that inhalation burns were often not recognised, could present late, and usually had significant consequences. Early clinical diagnosis, supported by endoscopic findings and appropriate management, is essential if the high morbidity and mortality amongst these children is to be improved.

Intestinal ulceration, obstruction, and haemorrhage in congenital syphilis.
Intestinal obstruction and bleeding are uncommon complications of congenital syphilis (CS). A VDRL-positive infant developed incomplete intestinal obstruction and rectal bleeding. Despite conservative management, his symptoms continued. At laparotomy, terminal ileal inflammation and stenosis were demonstrated. He underwent ileal resection and primary end-to-end anastomosis with resolution of his symptoms. Histopathological examination demonstrated heavy plasmacytic infiltration of the lamina propria and submucosa with ulceration of the mucosa, consistent with syphilitic ileitis. This report documents for the first time bleeding from ileal ulcers associated with intestinal obstruction in CS and highlights an unusual presentation of the disease.

Intrahepatic fetus-in-fetu: a case report and review of the literature.
The authors report the third case since 1964 of fetus-in-fetu presenting at Red Cross Children's Hospital. A fetal liver abnormality was detected during routine antenatal ultrasound scan, and the postnatal diagnosis of an intrahepatic, multiple fetus-in-fetu was made with abdominal ultrasound scan, plain radiograph of the abdomen and computed tomography. The mass was removed surgically by hemihepatectomy when the patient was 4 months of age. Imaging and the macroscopic and microscopic appearances of the abnormality confirmed the diagnosis and amplified it to include an adjacent teratoma. Multiple small subcapsular and perimass vascular hamartomas were coincidentally discovered in the liver. Two of the 3 nodules within the amniotic-lined cavity of the intrahepatic mass individually comply with the accepted criteria for fetus-in-fetu, and the third nodule has the accepted features of a benign teratoma. The existence of multiple fetus-in-fetu and fetus-in-fetu combined with a teratoma, is recorded in the medical literature. The imaging as well as the macroscopic and microscopic features are illustrated.

The use of diverting colostomies in paediatric peri-anal burns.
Over a 3 yr period we performed colostomies in 13 paediatric perineal burn patients out of a total of 1544 patients admitted to our Burns Unit during that period. The mean total body surface area (TBSA) burn was 34% (14-65%); ten patients sustained fire burns and the remaining three hot water burns. We performed prophylactic colostomies in seven children, therapeutic colostomies (to counteract deep wound infection and septicaemia with gut-derived organisms) in five patients and one colostomy in a cerebral palsy child with a left hemiparesis. A sigmoid end-colostomy with Hartmann's closure of the distal segment was the preferred method of choice. In all children but one (died from multi-organ failure 13 days after admission) there was a marked improvement in the clinical appearance of the burn wounds and subsequent graft-take and healing. There was a change in the bacterial profile away from predominantly gut-derived Gram negative organisms to either Pseudomonas aeruginosa or no pathological organisms grown. Complications were few--two children suffered prolapse of their colostomy requiring manual reduction. We advocate diverting colostomies in a highly select group of paediatric burn patients in whom continual faecal soiling is threatening to both graft and life.

Perianal candidosis--a comparative study with mupirocin and nystatin.
OBJECTIVE: To assess the efficacy and clinical outcome of 2% mupirocin in a polyethylene glycol base and nystatin cream as treatment regimens in diaper candidosis. DESIGN: A prospective randomized comparative study. METHODS: In vitro. The susceptibility of 20 clinical isolates of Candida albicans to 2% mupirocin, nystatin, and five additional antifungal agents was evaluated using the Nathan agar-well diffusion assay. The minimum inhibitory concentration (MIC) of mupirocin against the Candida species was determined using a tube dilution method. In vivo. Twenty patients (mean age, 12 months; range, 1 month to 4 years) with moderate to severe Monilia diaper dermatitis either had mupirocin ointment or nystatin cream applied to the infected area every 8 h or after every diaper change for a period of 7 days. Microscopic examination of skin scrapings and mycologic and microbiological cultures were performed before treatment and daily for 7 days, and progress was clinically assessed. RESULTS: In vitro. Topical mupirocin produced a greater zone of inhibition than nystatin cream, i.e. a mean of 27.2 mm (SD 1.55) compared with a mean of 17.3 mm (SD 1.08) for nystatin cream. MIC for mupirocin of 512 microg/mL in one case, 256 microg/mL in six cases, 200 microg/mL in 10 cases and 400 microg/mL in three cases were obtained for the 20 clinical isolates. C. albicans also displayed a universal sensitivity to mupirocin and nystatin. In vivo. Eradication of all Candida organisms was achieved within 2-6 days (mean, 2.6 days) in 10 patients receiving topical mupirocin therapy with rapid healing of the excoriated wounds (mean, 4.7 days). Both Gram-positive and Gram-negative bacteria were eradicated from the infected area within the trial period. Ten patients received topical nystatin cream and, in each case, Candida was successfully cleared within 5 days (mean, 2.8 days). Only three wounds were clinically healed within the trial period, however. The remaining seven wounds showed evidence of improved, but ongoing excoriated dermatitis and a heavy growth of polymicrobial organisms. CONCLUSIONS: Both agents eradicated Candida, the major difference being the marked response of the diaper dermatitis to mupirocin. Mupirocin should be applied topically 3-4 times daily or with each diaper change and is an excellent antifungal agent.

Neonatal Soave endorectal pull-through for Hirschsprung's disease.
In October 1994 we changed our management of neonatal Hirschsprung's disease from a staged procedure after initial colostomy to a neonatal single-stage Soave endorectal pull-through (SERPT) without a colostomy. We report on our experience with the first 12 neonatal SERPTs, comparing them retrospectively with a consecutive series of 12 patients managed with initial colostomy, followed by a SERPT months later. A neonatal SERPT proved to be an easier and quicker procedure than the same procedure in the older child. Patients could be discharged earlier and fewer complications were encountered; in addition a colostomy was avoided. The cosmetic result and parental acceptance were excellent. At the same time the cost was less than half compared with the staged group. At this stage of follow-up functional results are comparable with previous staged pull-through procedures.

Oesophageal replacement in the management of corrosive strictures: when is surgery indicated?
The accidental ingestion of corrosive agents is a major cause of oesophageal strictures in children. The mainstay of treatment is repeated dilatations. Despite this, a significant number of patients eventually require oesophageal bypass. We reviewed the records of all cases managed with this condition at the University of Cape Town teaching hospitals between 1976 and 1994. Dilatation therapy alone was successful in 14 out of 39 patients (41%). Morbidity of failed dilatation therapy included repeated hospital admissions over an average 11.5 months and 17 dilatations each. Oesophageal perforations occurred in 7 cases (18%). Early factors predictive of failure of conservative treatment were: delay in presentation of more than 1 month; severe pharyngo-oesophageal burns requiring a tracheostomy; oesophageal perforation; and a stricture longer than 5 cm on radiological assessment. The size of dilators accepted during early bougienage also correlated with eventual outcome. These criteria may be useful in predicting which patients will not respond to repeated dilatations. Early surgical intervention in such cases will prevent fruitless dilatations and related complications.

Prediction of outcome in congenital diaphragmatic hernia.
The case records of 59 patients with congenital diaphragmatic hernia (CDH) who presented between 1984 and 1997 were studied retrospectively. Included in the study were infants born with CDH who required respiratory support within the first 6 h of life. Twenty-three were excluded from the study for various reasons; 36 were enrolled in the study; the male-to-female ratio was 18:18. Twenty-nine hernias were left-sided and 7 were right-sided. All patients were ventilated using conventional techniques. Arterial blood gases were measured on average 1.76 h following admission and the initial period of resuscitation (range 1-4 h). Three formulae were applied in an attempt to predict outcome: ventilation index against PCO2, alveolar-arterial oxygen gradient, and a newly derived formula from this institution (Red Cross formula) that comprises respiratory rate x PCO2 x FiO2 x mean airway pressure/PaO2 x 6000. Seventeen patients (47.2%) survived and 19 died (52.8%); 21 became stable enough to undergo surgery. The average time from presentation until surgery was 1.98 days (range 6 h to 4 days). The Red Cross formula, with a 100% predictive value for mortality, 85% predictive value for survival, and an overall predictive value of 91.6%, appeared to be superior to the other formulae studied. The availability of a highly accurate predictive formula may facilitate management of this frequently lethal disease.

Molecular cloning of IgE-binding fragments of Alternaria alternata allergens.
Exposure to the hyphomycete Alternaria alternata is recognized as an important risk factor for asthma. IgE immunoblotting has been used to catalogue the number and Mr of allergens in A. alternata extracts, with estimates ranging from 10 to 30, although few are present in nearly all extracts studied. Several A. alternata allergens have been cloned, including a subunit of the major allergen Alt a 1, ribosomal P2 phosphoprotein, aldehyde dehydrogenase and a yeast YCP4 homolog. We have cloned two sequences encoding IgE-binding fragments of allergens from an A. alternata lambda gt11 cDNA library using pooled atopic sera from A. alternata-sensitive individuals. One is homologous to a region near the C-terminus of hsp70 from Cladosporium herbarum; a near-complete isoallergen variant of A. alternata ribosomal P2 protein was also cloned. Their lacZ fusion proteins had reactivities of 5 and 14%, respectively, with individual atopic sera, indicating that the corresponding allergens are both minor. This study describes one new A. alternata allergen candidate and implicates ribosomal P2 protein as an allergen thtat is stable between independently isolated clones.

Sacrococcygeal germ-cell tumours--the Red Cross War Memorial Children's Hospital experience, 1980-1996.
OBJECTIVE: To document the experience of Red Cross War Memorial Children's Hospital in the treatment of sacrococcygeal germ-cell tumours. PATIENTS: Twenty-seven patients with sacrococcygeal germ-cell tumours were treated in our hospital from 1980 to 1996. DESIGN: A retrospective review of these patients' records was undertaken. RESULTS: There were 19 female and 8 male patients. Seventeen (63%) presented in the neonatal period, 13 on the first day of life. Complete surgical resection of the tumour was achieved in all patients with mature or immature teratomas (20 patients) and in 2 neonates with malignant tumours. The first of these 2 neonates, with a malignant teratoma, was not given chemotherapy and remains well 10 years later. The second, with a yolk-sac tumour, also received no initial chemotherapy. He relapsed at the age of 9 months and was successfully treated with repeat excision and chemotherapy. All 5 patients first diagnosed after the age of 1 year had malignant tumours. These patients had incomplete surgical resection (3) or biopsy only (2), and 3 were successfully treated with chemotherapy. One patient relapsed with yolksac tumour after initial complete resection of a mature teratoma. She was successfully treated with repeat surgery and chemotherapy.
