    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).

    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.
