Electrolyte abnormalities in lymphosarcoma after chemotherapy.

A 12-year-old female with lymphosarcoma responding to treatment including vincristine and cyclophosphamide developed clinical and laboratory findings compatible with the syndrome of inappropriate secretion of antidiuretic hormone. Some additional findings were observed, i.e. uremia, hypopotassemia and alkalosis, that have not so far been recorded in that syndrome. All abnormalities were corrected upon water restriction. A similar episode occurred after a 2nd drug course. It too was corrected upon water restriction. The patient was clinically free from her malignancy in both episodes. It is suggested that our child had probably an expanded form of the syndrome of inappropriate secretion of antidiuretic hormone.

Increased urinary catecholamines in an infant with the diencephalic syndrome.

In an infant of 15 months with the diencephalic syndrome, urinary excretion of norepinephrine was moderately raised and epinephrine greatly so. It is suggested that catecholamine secretion may be due to sympathetic stimulation at the level of the diencephalon, by a space-occupying lesion pressing on the thalamohypothalamic pathway. Some of the symptoms of the diencephalic syndrome such as euphoria, irritability, skin pallor, and hypertension may be the result of catecholamine secretion.

Chronic lymphoglandular enlargement and toxoplasmosis in children.

Serum antitoxoplasma titres were determined simultaneously by the direct agglutination and the indirect immunofluorescent tests in 52 children aged 2 to 16 years having chronic lymph node enlargement, mainly cervical. Direct agglutination titres were raised (64 to 4096) in 22 children (42%), but rarely in the control groups of children with acute suppurative lymphadenitis, and healthy children, adults, nurses, and physicians. It is concluded that toxoplasmosis is commoner in Greek children than previously believed, and that it should be included in the differential diagnosis of lymphoglandular enlargement. Clinically the condition is mild and may be self-limited, but it should be treated promptly with trimethoprim-sulphamethoxazole, in order to prevent reactivation in adult life.

Immunoglobulin E in erythema nodosum.

Twenty-two children aged from 3 years 6 months to 12 years with erythema nodosum (EN) were grouped according to aetiology into streptococcal, tuberculous, and those whose aetiology was undetermined. Serum IgE levels were determined in all by the radioimmunosorbent technique. Levels were higher (mean value 991 units/ml) in streptococcal EN than in those of the other two groups (mean value 68 units/ml and 97 units/ml, respectively) and healthy age-matched controls (mean value 60 units/ml). Increase of IgE levels in individual cases of streptococcal EN did not correlate with severity of the clinical manifestations characteristic of that group.
