The general control group included 30 healthy children (15 d and 15 ~?, 1-13 yrs old).

The largest increase was seen in children 0.4 years of age. Health department, hospital, and clinic records of cases of TB in children 0-4 years reported in 1989, 1991, and 1993 in San Diego County were reviewed. Data collected included demographic information; country of birth; immigration status of the child and parents; and source case. Records of 85/89 (96%) TB cases were reviewed. HIV serology was negative for the 7 (8%) with known results. Of the 85 cases, 17 (20%) were foreign-born, 14 of whom were born in Mexico. Of the 68 US-born cases, 59 (87%) were Hispanic; 22/68 (32%) had immigrant parents (20 from Mexico), 17 (25%) others were reported to visit family in Mexico. Of the 17 immigrant parents of the 22 USborn children for whom date of entry into the US was known, 11 (65%) arrived less than 2 years prior to diagnosis in the child. A presumed source case was identified for 35 (51%) US-born cases; of these, 15 (43%) were parents, 10 (67%) of whom immigrated from Mexico, 9 (26%) a relative, 6 (17%) a neighbor or family friend, 4 (11%) a housemate, and 1 a sibling. At least 56/85 (66%) cases were in children who immigrated from a country where TB is highly endemic, or the child was US-born and the parents were immigrants, or there was extended family in Mexico.

Magnetic resonance imaging findings were typical of multiple cerebral ischemic infarcts. It is suggested that during the period of secondary viremia varicella zoster virus invaded the cerebral blood vessels causing vasculopathy and cerebrovascular infarcts.

The medical records of all children 0 to 14 years of age with NTM superficial lymphadenitis who were diagnosed at P. and A. Kyriakou Children's Hospital between January, 1982, and December, 1997, were reviewed. Forty-seven children were identified, 76.5% during the second half of the study period. Mycobacterium avium complex was the predominant isolate. Children with NTM lymphadenitis noted satisfactory aesthetic results when total excision was performed within 1 month after its onset. NTM superficial lymphadenitis in children has been increasingly recognized during the last decade. Prompt total excision of the involved lymph node is required in such patients.

Serum SGOT and SGPT levels were determined before INH administration and at 4-weekly intervals thereafter. Levels of both enzymes were raised during the first 3 months of treatment in 18 (7.5%) children, while in 23 (9.6%) children either SGOT or SGPT exceeded normal levels (SGOT greater than 40 units, SGPT greater than 30 units). Only 2 (0.8%) children showed SGOT and SGPT values above 100 units and in them treatment with INH had to be discontinued. In all other children transaminases returned to normal during uninterrupted INH administration. It was noted also that transaminase values in children who did not exhibit a rise above normal, still had significantly higher levels during treatment compared with before. The findings of this study suggest that liver injury in children receiving INH for prophylaxis occurs more often than it had hitherto been believed but that it is usually mild and transient.
