We report on the unusual finding of both symptomatic biliary and renal calculi in a child. A review of the literature failed to provide any definite common etiologic factors, although the possible role of systemic infection cannot be ruled out.
Reported is a child who at the age of 18 months had presented with a left retinoblastoma. The lesion had involved the optic nerve (Stage IV), and was successfully treated by enucleation and radiotherapy. The radiation field did not include the mandible or the submandibular triangle. He was followed up until he left the area aged 11 years. He represented aged 12 years with a progressive swelling of the left submandibular gland. Histology of the surgically excised submandibular gland revealed a mucoepidermoid carcinoma of the submandibular gland. This case highlights the need for continual surveillance in survivors of retinoblastoma, as second primary tumours occur both within and outside of previous radiation fields. The clinical association between retinoblastoma and mucoepidermoid carcinoma of the submandibular gland has not been previously reported.
In a study of gastric emptying on 28 children using applied potential tomography, we have shown that a group of children with delayed gastric emptying can be identified, including those with proven hypertrophic pyloric stenosis. The place of APT in the investigation of gastric emptying in children is discussed, and in particular its usefulness in early confirmation of HPS in equivocal cases.
Over a five year period 55 fetuses had abnormalities of the urinary tract detected by antenatal ultrasound scan. The incidence was 1:935 total births during a one year prospective study. Intrauterine intervention was undertaken in five for suspected obstructive uropathy, which was confirmed in only two. Of 51 live born infants, five died (two with renal failure), and only 18 (35%) had a clinically detectable abnormality at birth. Twenty seven patients underwent postnatal operations, the remainder being treated conservatively. Antenatal counseling was seldom undertaken by those responsible for the postnatal care. There were many instances of prospective parents receiving little or inappropriate information. Greater cooperation is required between all the staff concerned particularly as the natural history and appropriate postnatal management of some urinary tract abnormalities are still not known.
Sulbactam is a beta-lactamase inhibitor, which when administered with ampicillin, increases the latter agents antibacterial activity against beta-lactamase producing organisms. One hundred children between the ages of 5 and 14 undergoing emergency appendectomy were entered into a prospective randomized trial comparing sulbactam and ampicillin (SA) with metronidazole and cefotaxime (MC) as prophylaxis against postoperative wound infection. Patients in whom the appendix was perforated or gangrenous received a 72-hour course of antibiotics, others received a single dose only. The overall wound infection rate was 8% (14% in patients with perforation or gangrene and 4% in those without). There was no difference in infection rate between the two antibiotic groups; there were three wound infections and one subphrenic abscess in patients receiving SA and four wound infections in patients receiving MC. SA, therefore, appears to be a suitable antibiotic combination for use as prophylaxis in appendicitis in children.
The surgical management of posterior urethral valves remains controversial. To examine the effects and results of operative treatment in boys with proven posterior urethral valves, a retrospective study was undertaken. The case records of 33 male children who presented with posterior urethral valves over a 10-year period were reviewed. Two patients died prior to definitive treatment and one died postoperatively. Following resuscitation and diagnostic procedures, the remaining patients had eradication of the posterior urethral valves by electrothermic fulguration. In 14 patients this was performed using the Innes-Williams diathermy hook under control of contrast enhanced radiography. In 16 patients the valves were fulgurated under direct cystoscopic visualization. All surviving patients had an uneventful postoperative recovery. However, of those undergoing cystoscopic fulguration, four developed symptomatic urethral strictures necessitating repeat cystoscopy and urethral dilatation. No cases developed strictures following the use of the diathermy hook. One patient from each treatment group developed dribbling. The Innes-Williams diathermy hook has been proven to be a safe, simple, and inexpensive technique. This has specific application in the neonate and small infant where cystoscopy poses technical problems because of anatomic size and where potentially traumatic urethral instrumentation should be avoided.

Twenty-four-hour esophageal pH monitoring was performed in 59 children with symptoms of gastroesophageal reflux using a miniature pH electrode and a portable recording system to establish the diagnosis. Significant reflux was seen in 26 (44%) of the patients and these were treated for six weeks with cimetidine, Gaviscon, and Nestargel. Five children who did not improve either symptomatically or on repeat pH monitoring while on treatment underwent antireflux surgery. The pretreatment reflux index in this group was 26.5 compared with a pretreatment reflux index of 11.2 in the 21 patients who improved on therapy (P less than 0.01). Esophageal pH monitoring has enabled selection of children for surgery and may be used as an early indicator of those who will not benefit from long-term medical therapy. Ambulatory and home monitoring techniques are more convenient and cost-effective and allow studies to be performed in the normal home environment.
Duplications can occur anywhere in the alimentary tract from mouth to anus. There may be multiple duplications in about 15% of cases. The most common site is in the distal ileum, in over 50% of cases. Duodenal duplications are rare, and occur in only 5-10% of the total in recent reviews (3, 5, 7). Three cases of this very uncommon abnormality are reported.
Critically ill infants with congenital diaphragmatic hernia were treated by either early surgery or delayed surgery after preoperative stabilisation. The preoperative stabilisation was aimed at correcting acidosis and hypoxia, thereby reducing the severity of persistent fetal circulation. Survival improved from 12.5% after early surgery to 52.9% after delayed surgery.
A 4-week-old male presented with a swelling in the right groin. At herniotomy a megaureter was discovered and a subsequent IVU demonstrated bilateral megaureters.
Thirteen children, ranging in age from 45 days to 2 years, had severe gastrointestinal illness with the features characteristic of neonatal necrotising enterocolitis. All 13 children had preceding gastroenteritis leading to hypovolaemia. Necrotising enterocolitis can occur in children beyond the neonatal age group and it may occur as a sequel to gastroenteritis.
