Urine gamma-glutamyl transferase in rat kidney toxicology: nephropathy by repeated injections of mercuric chloride. Effects of sodium selenite.

Groups of 5 male and 4 female Cobs CD rats weighing 250--350 g were injected intraperitoneally, daily for 15 days, with 5 mumol HgCl2/kg, 5 mumol Na2SeO3/kg, or (5 mumol HgCl2 + 5 mumol Na2SeO3)/kg in a 10 ml/kg vol. of saline. Control animals were injected with saline only. Injection of saline or sodium selenite produced neither modification of diuresis, nor of urine elimination of sodium, potassium, chloride, phosphates, urea, creatinine and gamma-glutamyl transferase (GGT). Injection of mercuric chloride induced a massive increase of urine GGT, diuresis and phosphaturia and a decrease of kaliuria and natriuria. Those effects reflect a kidney tubular lesion which seems to be more severe in males than in females. Injection of mixed sodium selenite and mercuric chloride or separate injection of both compounds had similar effects. In both sexes, urine GGT elimination was delayed and about 2 times lower than with HgCl2 alone. In females, the other urine parameters were almost normal whereas in males, diuresis and phosphaturia were slightly increased and kaliuria decreased. The observation of urine GGT elimination attests, in vivo, that sodium selenite decreases tubular toxicity of mercuric chloride and resulting kidney function disturbances.

Disseminated lupus vulgaris and papulonecrotic tuberculid: case report.

The incidence of tuberculosis and extrapulmonary forms of this disease is increasing all over the world. Lupus vulgaris is the most prevalent form of cutaneous tuberculosis in Europe and the Middle East. Papulonecrotic tuberculid, the most common form of hyperergic response to mycobacteria or their fragments, is uncommon in children. We report lupus vulgaris with papulonecrotic tuberculid in a 12-year-old girl who had a 3-year history of slowly growing plaques on her trunk, extremities, and the tip of her nose and papuloulcerative lesions over her entire body. A skin biopsy specimen showed minimally caseating granulomatous inflammation. Staining for acid-fast bacilli was negative in both plaques and papules. Polymerase chain reaction identified Mycobacterium tuberculosis DNA in the patient's sputum, gastric fluid, and plaques and was negative in the papules. She was started on antituberculous therapy with four drugs and her lesions responded rapidly.

The impact of pre- and perinatal factors on attention-deficit and disruptive behavior disorders.

Diagnosis of attention-deficit and disruptive behavior disorders defines a group of disorders which have common properties. This group consists of attention-deficit hyperactivity disorder, conduct disorder and oppositional defiant disorder. In order to differentiate these disorders, which share similar properties, it is important to verify the existing differences. In this respect, differences between and distribution of perinatal factors in these three disorders were investigated. The study was conducted in the Child Psychiatry and Pediatric Neurology Departments over a 20-month period. Two hundred and seventy children out of 1,556 attendant with various complaints were diagnosed to have one of the following disorders: 121 had attention-deficit hyperactivity disorder, 50 had oppositional defiant disorder and 99 had conduct disorder. The prenatal and perinatal data of the patients were evaluated retrospectively by a neonatologist. With regard to the investigated parameters, none showed any significant difference between the three groups when compared. The three disorders, which share many similarities in terms of the symptoms, also show similarities in terms of perinatal factors. Since we did not find any study similar in design, our results, although statistically not significant, are discussed in light of the little data available.
