Effect of influenza immunization on immunologic and virologic characteristics of pediatric patients infected with human immunodeficiency virus.

OBJECTIVES: We evaluated the responses of HIV-infected children to a single dose of split-virus influenza vaccine and the relationship to viral load and other characteristics. METHODS: Fifty-three HIV-infected children ages 1.8 to 13.2 years were given influenza vaccine for the 1994 to 1995 influenza season (Wyeth-Ayerst: A/Texas H1N1, A/Shangdong H3N2 and B/Panama). Immunologic and virologic factors were assessed at the time of and 2 to 10 weeks after immunization. RESULTS: The differences between pre- and postimmunization CD4+ counts, CD4+:CD8+ ratios and viral load were not significant. Thirty-one of 53 children (58.4%) had a > 2-fold increase and 16 of 53 (30%) had a 4-fold rise in their postimmunization antibody titers for at least one component of the vaccine. Influenza immunization in the 1993 to 1994 flu season and administration of intravenous immunoglobulin around the time of immunization was not associated with immune response to the vaccine. Factors that were negatively associated with antibody response included increased time between samples (P = 0.004) and decreased preimmunization CD4+:CD8+ ratio (P = 0.02). CONCLUSIONS: Influenza immunization in this population is safe, and a positive antibody response to influenza immunization is not associated with significant clinical events or change in HIV-1 plasma viral burden.

Use of computers in dysmorphology.

As a consequence of the increasing power and decreasing cost of digital computers, dysmorphologists have begun to explore a wide variety of computerised applications in clinical genetics. Of considerable interest are developments in the areas of syndrome databases, expert systems, literature searches, image processing, and pattern recognition. Each of these areas is reviewed from the perspective of the underlying computer principles, existing applications, and the potential for future developments. Particular emphasis is placed on the analysis of the tasks performed by the dysmorphologist and the design of appropriate tools to facilitate these tasks. In this context the computer and associated software are considered paradigmatically as tools for the dysmorphologist and should be designed accordingly. Continuing improvements in the ability of computers to manipulate vast amounts of data rapidly makes the development of increasingly powerful tools for the dysmorphologist highly probable.

Myotonic dystrophy and hyperparathyroidism: association with neurofibromatosis and multiple endocrine adenomatosis type 2A.

Four patients with hyperparathyroidism associated with myotonic dystrophy have been identified. All were females aged between 2 and 45 years. They were from three separate families, with two related patients being mother and daughter. In addition, one patient had medullary carcinoma of the thyroid and was diagnosed as having multiple endocrine adenomatosis, type 2A; another had an unspecified thyroid carcinoma; a third patient had neurofibromatosis. Our data suggest that myotonic dystrophy may somehow be associated with one or more of these disorders of neural crest origin.

Hypercholesterolemia associated with alpha-1 antitrypsin deficiency and hepatitis: lipoprotein and apoprotein determinations, sterol balance and treatment.

Lipid metabolism was investigated in a 4-year-old boy with alpha-1 antitrypsin deficiency (ZZ phenotype) and liver disease. Plasma cholesterol and triglyceride levels were 604 mg/dl and 336 mg/dl respectively. Both parents had normal plasma lipids. Lipoprotein X was present at a concentration of 855 mg/dl and levels of apoproteins A-I, A-II, B and C-III were elevated. The plasma free fatty acid pattern was normal. Plasma cholesterol esterification was greatly depressed. Cholesterol absorption on two occasions was reduced about 13% compared with adult controls. Neutral and total steroid excretion was normal with increased excretion of bile acids. A low-cholesterol, low-fat diet reduced plasma cholesterol to 374 mg/dl and triglyceride to 236 mg/dl in two months. Cholesterol and lipoprotein X concentrations were elevated far out of proportion to the severity of the liver disease (total bilirubin 3.7 mg/dl, SGOT 280 IU/L). This suggests that lipoprotein metabolism in patients with this disorder is unusual and may differ from the derangements seen in other forms of liver disease.
