    Notes: Butylated hydroxyanisole (BHA) at 150 ppm, and tertiary butylhydroquinone (TBHQ) at 100 ppm, were tested against Staphylococcus aureus A100 in the presence of 50 and 100 mM Ca2+ or Mg2+. The inhibitory activity of BHA was increased by the presence of Ca2+ but not Mg2+ in the suspending buffer. An increase in Ca2+ concentration did not cause additional increase in the activity of this compound. With TBHQ, there was no apparent increase in antibacterial activity by the presence of either Ca2+ or Mg2+.

    Non-tuberculous mycobacterial lymphadenitis in children (1989)

    Notes: Abstract Eighty-six children (44 males, 42 females) were identified as having non-tuberculous mycobacterial lymphadenitis. The diagnostic criteria were either culture of the organism from the affected lymph node (n=68), or, when culture was negative, a positive skin test with non-tuberculous mycobacterial antigens and negative skin test responses to tuberculin purified protein derivative (PPD) in association with typical histological features (n=18). All children had histopathological findings of granulomatous inflammation with caseation and/or acid-fast bacilli. Eighty-two percent of the children were under 5 years of age at presentation and 30% were less than 2 years old. Most (79%) were city dwellers. Lymph node enlargement had been present for less than 6 months in almost all children (97.5%) and was almost exclusively in the face and neck region (97%). Disease was confined to the involved lymph nodes in 56% but had extended beyond the confines of the infected node to form a collar stud abscess in 38% and 6% presented with a skin sinus. Extranodal extension did not show any statistically significant association with the duration of lymphadenopathy. The duration of lymphadenopathy had been greater in those children in whom an organism was not isolated on culture resected tissue χ2, P〈0.01). All children were treated surgically, and recurrence occurred in five patients. This study describes the clinical and demographic characteristics of non-tuberculous mycobacterial lymphadenopathy in children in a population in which tuberculous adenitis is rare. Recognition of these features may allow earlier diagnosis and appropriate surgical therapy.

    Lymphocyte production of gamma-interferon as a test for non-tuberculous mycobacterial lymphadenitis in childhood (1993)

    Notes: Abstract Infection withMycobacterium avium, M. intracellulare and M. scrofulaceum (MAIS) organisms in normal children may result in cervical lymphadenopathy. There is a poor response to anti-tuberculous therapy and surgical excision of infected nodes is necessary. The diagnosis therefore requires consideration in children with cervical lymphadenopathy. A simple in vitro assay is described which may be useful for diagnosis prior to excision. Whole blood is cultured withM. avium purified protein derivative. After 24h the plasma is removed and the concentration of gamma interferon (IFN-γ) quantified by a radioimmunometric assay. In a prospective study of 38 children with neck lesions, 16 showed MAIS organisms isolated from cultures of excised tissue. The level of IFN-γ produced by peripheral blood lymphocytes from children in the MAIS group was significantly greater when compared with children having operations for neck lesions that were not due to MAIS organisms (P〈0.001).

Die korrekte Richtigstellung wurde in einer Arbeit des Verfassers angegeben. Eine Eigenschaft, die Pöschl und Teller einer vom Verfasser nach der Wellenmechanik behandelten Potentialfunktion zuschreiben, ist infolge einer Zweideutigkeit in der Definition miß-verständlich. — Die Quantelung der Bewegungen für die von Pöschl und Teller angegebenen interessanten PotentialfunktionenV 1 undV 2 wird zur Illustration des Problems nach der älteren Quantentheorie durchgeführt.

    Graded compression ultrasonography in the assessment of the “tough decision” acute abdomen in childhood (1999)

    Notes: Abstract The diagnosis of acute appendicitis in childhood is frequently difficult. In some situations the need to operate is clear, but in others the decisions may be much “tougher” because the clinical findings are equivocal. This is a retrospective study of a consecutive series of 253 children presenting with “acute abdominal pain? appendicitis” who had graded compression ultrasonography (GCUS) because the clinical scenario did not warrant immediate laparotomy. This represents 30% of all cases seen in the study period. The aim of the study was to examine the role of GCUS and a clinical scoring system (the Alvarado score) in patients in whom the diagnosis is uncertain.

    Notes: Abstract Since 1955, 56 children (29 M: 27 F) with primary liver tumours have been treated at the Royal Children's Hospital. Ranging in age from neonates to 14 years, they most frequently presented with an abdominal mass. The position, size, and vascularity of the tumour were assessed preoperatively by ultrasound +/− angiography. An elevated serum alpha-feto-protein was confirmatory evidence of a hepatoblastoma. In the malignant group (33), 70% of the children had tumour resection with 5 “surgical” deaths. The long-term survival in the resected group was 15/23 (65%). No children survived without resection. In the benign group (23), 8 children had an arteriovenous malformation (7 neonates). Six are alive and well following hepatic lobectomy with 1 dying of cardiac failure before the diagnosis was established. The other benign tumours were either removed by local excision (10), lobectomy (3), or biopsied (2). All children are alive and well. In those children requiring hepatic lobectomy, hypothermia and hypotension were used as adjuncts to anaesthesia. The commonest operative complication was blood loss (50%). The technique of total vascular isolation was introduced in 1975 and reduced the incidence to 16%. The use of chemotherapy enabled subsequent tumour resection in 4 of 5 tumours that were initially unresectable. Chemotherapy was also given postoperatively to 8 of 17 patients surviving resection.

    Notes: Abstract Hydrohaematometrocolpos may occur secondary to isolated imperforate hymen, genital tract duplications, and complex urogenital sinus or cloacal abnormalities. The presenting symptoms and relation to menarche provide clues to the diagnosis. Examination of the abdomen, introitus, and vagina may confirm the diagnosis and assist in clarification of the anatomy. In genital duplications ultrasonography further delineates the pelvic anatomy and demonstrates unilateral renal agenesis. We have reviewed our 10-year experience and present an approach for the diagnosis and investigation of these patients.

    Notes: Abstract During the years 1979–1988, 63 children (38 male: 25 female) were first diagnosed as having Crohn's disease on the basis of histological findings. Twenty-nine per cent were less than 10 years old at the onset of symptoms; 40% of these cases took more than 1 year to diagnose. Most patients (59%) presented with abdominal pain and diarrhoea, but 40% presented with: a non-specific illness (14%); upper gastro-intestinal tract symptoms (14%); growth failure (6%); systemic disease (5%), or peri-anal disease (1%). There were signs of abdominal tenderness, distension, or an abdominal mass in over 50% of cases. Peri-anal Crohn's disease was present in 41% and a height less than the 10th centile was recorded at diagnosis in 45%. Children were treated with a combination of prednisolone and sulphasalazine. In 16 cases a bowel resection was performed. Surgery was indicated for localised stricture formation causing obstruction and for persistence of severe disease poorly responsive to steroids, particularly in the prepubertal child with growth failure. The extent and distribution of disease influenced outcome. Twenty-four of 39 children followed for more than 3 years are either well-controlled or disease-free at present.
