Four cases of neonatal non-ketotic hyperglycinaemia.

Non-ketotic hyperglycinaemia is an autosomal recessive disorder of glycine metabolism caused by a defect in the glycine cleavage system. Affected neonates present with lethargy, feeding difficulty, hypotonia, apnoea, poorly controlled convulsions and coma. Four cases are reported, three of whom died in the neonatal period.

Effect of BCG vaccine on tuberculin skin tests in 7-11-year-old children.

Aim: To determine the effect of Bacillus Calmette Guerin (BCG) vaccination on tuberculin skin test responses in 7-11-year-old children, and also to clarify whether the number of vaccinations and the time interval between vaccination and tuberculin skin test have an effect on the test responses.

Method: 1200 primary school children were evaluated for the presence and number of BCG scars. They were then given 5 TU PPD-S intra-dermally.

Effect of BCG vaccine on tuberculin skin tests in 1-6-year-old children.

Unlabelled: Bacillus Calmette Guerin (BCG) vaccination used in the prevention of tuberculosis may cause problems in interpreting the tuberculin skin test (TST), which is commonly used in the diagnosis of infection. A limited number of studies have been undertaken to investigate how length of time after BCG vaccination affects TST results. TST induration values of unvaccinated children were compared with those of children vaccinated once in order to determine the changes in TST responses after BCG vaccination.
