Lymphocyte subpopulations in children with abnormal lymphatic circulation.

Peripheral blood lymphocyte subsets were enumerated in five children with abnormal lymphatic circulation (three with lymphangiectasia, one with chylothorax, and one child with chyloperitoneum). All patients were lymphopenic. The percentage and absolute number of blood T-lymphocytes (CD3) were low in two children and normal in the other children. The percentage and absolute number of helper/inducer lymphocytes (CD4) were markedly reduced in all patients. The percentage of suppressor/cytotoxic lymphocytes (CD8) was normal or elevated in all children, and the absolute number of CD8 cells was normal in three patients. The CD4/CD8 ratio was reversed in all patients. In the two patients tested, the proliferative response of peripheral blood mononuclear cells to mitogens was reduced. T-lymphocyte subsets were measured in the pleural or peritoneal fluid of three patients, and the CD4/CD8 ratio was normal or increased. In each child, the CD4/CD8 ratio in the lymphatic fluids was markedly higher than the CD4/CD8 ratio of the blood (4.0/0.45, 1.75/0.95, and 1.3/0.85). The reversed CD4/CD8 ratio in the blood in cases of chronic loss of chyle may be due to either selective transport of CD4 lymphocytes into the lymphatic fluids or a shorter half-life of CD8 compared to CD4 lymphocytes. This finding may in part explain the abnormal cellular immunity previously observed in patients with lymphangiectasia.

False aneurysm of the right ventricle due to endocarditis in a child.

An eight-year-old boy with supravalvular pulmonic stenosis, supravalvular aortic stenosis, and ventricular septal defect developed Staphylococcus aureus endocarditis. The infection was complicated by formation of a false aneurysm of the right ventricular outflow tract, which was demonstrated by contrast echocardiogram. Surgical treatment was successful. This is a unique case of false aneurysm of the outflow tract of the right ventricle, because it is secondary to endocarditis without known previous trauma to the right ventricular wall.

Recurrent infections and staphylococcal liver abscess in a child with C1r deficiency.

Complete absence of the C1r portion of the first component of complement was found in a 2 1/2-year-old boy of Puerto Rican origin who presented with a staphylococcal liver abscess. His medical history also included two episodes of pneumonia complicated by a pneumatocele and empyema, purulent staphylococcal lymphadenitis, recurrent otitis media, and pneumococcal bacteremia. The C1s component of complement was 50% of normal, and C4 was elevated. Other immunologic tests, including nitroblue tetrazolium test, and IgE were normal. This is the tenth patient reported with C1r deficiency. The patient differs from other reported patients with C1r deficiency in that he presented with a liver abscess, an infection that has not been reported in patients with complement deficiencies, and in that he has an apparent susceptibility to staphylococcal infection.

Presternal swelling in mumps.

A case of presternal swelling associated with mumps is presented. presternal swelling occurs secondary to obstruction of the lymphatic drainage from the anterior-superior chest wall by the enlarged cervical salivary glands. The occurrence of this complication in mumps is discussed.

Autoantibodies to neuroblastoma cell surface antigens in neuropsychiatric lupus.

A human neuroblastoma cell line, LA-N-1 was used as a target cell in a I131 radiolabeled staphylococcal protein-A (I131-SpA) binding assay, to characterize the pattern of antineuronal activity of human sera in fifty-four cases of systemic lupus erythematosus (SLE) including twenty-six patients with neuropsychiatric manifestations of SLE (LE-CNS), out of which ten were pediatric patients aged eleven to eighteen years, thirty-six normal donors and sixteen rheumatoid arthritis patients. The IgG binding activity of normal control sera with LA-N-1 neuroblastoma cells was determined to be 998 +/- 490 cpm I131-SpA, per 5 micrograms LA-N-1 protein (mean +/- SD), 2936 +/- 2607 cpm I131-SpA per 5 micrograms LA-N-1 protein for rheumatoid arthritis patients, 5109 +/- 3304 cpm I131-SpA per 5 micrograms LA-N-1 protein for SLE patients. The binding activity of for LE-CNS patients sera was: 10 565 +/- 2993 and 15 346 +/- 2993 cpm I131-SpA per 5 micrograms LA-N-1 protein, for the pediatric and adult group of patients respectively. Absorption assays disclosed that the antineuronal IgG autoantibody detected in the LE-CNS group of patients is cross reacting with human adult brain, while the anti-neuronal activity of rheumatoid arthritis and SLE patients could be removed by sequential absorption with homogenates of human lung, liver, and kidney, fetal calf serum, human muscle and human lymphocytes. We conclude that detection of autoantibodies binding to LA-N-1 human neuroblastoma cells may be helpful in the diagnostic workup of pediatric and adult LE-CNS patients.

Hypernatremic dehydration and hypothermia in congenital lamellar ichthyosis.

Several events of hypernatremic dehydration occurred in five infants suffering from severe congenital lamellar ichthyosis. Simultaneously, four of them developed hypothermia. Both phenomena were probably caused by excessive water loss through the affected skin. In lamellar ichthyosis the skin loses its function as an effective barrier and therefore its role in water and temperature homeostasis is defective.

Processionary caterpillar dermatitis.

This work is the first description of processionary caterpillar dermatitis in pediatric patients. Seven children were exposed to caterpillar spines of the genus Thamatopoea Wilkinson; Tams, a pine tree caterpillar that is the main causative agent of caterpillar dermatitis in Israel. In all seven patients avoidance of re-exposure caused the symptoms to disappear within a few days. This disease should be considered in the differential diagnosis of dermatitis in children in endemic zones.

Hepatitis associated with propylthiouracil treatment.

A 12-year-old girl with hyperthyroidism who had started treatment with propylthiouracil (PTU) 100 mg tid developed hepatitis. The drug was stopped, and the clinical and laboratory findings of hepatitis disappeared within a week. She was not receiving other drugs that could cause hepatic damage, and investigations for various viral agents were negative. This is the ninth report of PTU-induced hepatitis. The clinical picture is similar to that of viral hepatitis. Recovery usually occurs after withdrawal of the drug, but there have been two fatal cases of PTU-induced hepatitis.
