Monitoring observations made on 60 operators involved in pesticide application work in godowns and warehouses and 60 matched control workers are reported. Occupational exposure history and medical history are noted. Biochemical investigations, plasma and RBC cholinesterase estimations are included along with medical examination of the workers. Workers were found to be mostly exposed to Celphos, DDVP, Malathion, Pyrethrum, etc, and the use of protective devices were very limited. Cases of significant reduction in plasma and RBC cholinesterase activity were found. Frequency of symptoms like dizziness, headache, lachrymation, burning sensation in eyes, nausea and anorexia, etc, were much more in the exposed workers. No cases of clinical poisoning attributable to occupational exposure to pesticides were reported by the workers.

The tetracycline class of antibiotics is infrequently used in clinical pediatrics due to its side effects: they include anorexia, nausea, vomiting and diarrhea. Hypersensitivity, a photosensibility reaction and a brownish discoloration of teeth is less frequently, a pseudotumor cerebri is rarely seen. Once therapeutic plasma levels are exceeded however, either by overdosage or decreased renal or hepatic clearance of the drug, serious complications like a secondary Fanconi-Syndrom or a nephrogenic diabetes insipidus can occur. The increased toxicity of tetracyclines in pregnant women is well known. We would like to report a fatal case, where serious complications like a secondary Fanconi-Syndrom, toxic degeneration of the liver, a clinically undected pancreatitis and a protein loosing enteropathy are though to be either direct consequences of tetracycline overdosage or the indirect effect of a shocklike syndrom by means of a nonoliguric renal failure induced by tetracycline.

The effects of synthetic salmon CT, administered subcutaneously and intermittently (1 MRC U/kg/day for 15 days/month over 6 months) were investigated in 15 uremic patients on regular dialysis treatment (RDT), all presenting various degrees of osteodystrophy. Clinically, osteoarticular pain disappeared in 8 out of 10 cases; 1 patient with rib fractures had a rapid calcification of the bone fracture repair tissue. No significant changes were found in serum calcium and PTH levels. Phosphotemia showed a significant decrease within the first 20 days. The varying individual hypophosphatemic response proved to be related to the initial level of phosphatemia. The alkaline phosphatase, when increased, showed a decrease to the normal range. A significant decrease in osteoclastic hyperactivity (active resorption surface, osteoclast index) and a slight increase in osteoblastic pool (active osteoid surface) were documented. No change was noted when osteomalacia predominated. Side effects included: anorexia, nausea, vomiting, face flushing. Our data suggest that salmon CT may be usefully employed in chronic uremic patients on RDT, when secondary hyperparathyroidism predominates.

Zinc deficiency may play a role in the etiology of anorexia nervosa. The symptoms of anorexia nervosa and zinc deficiency are similar in a number of respects, e.g., weight loss, loss of appetite, amenorrhea in females, impotence in males, nausea and skin lesions. In both conditions females under 25 are most at risk. Stress, estrogen and dietary habits may also be involved in the complex of factors which create or exacerbate a zinc deficiency and result in anorexia nervosa. It is proposed that effectiveness in the treatment of anorexia nervosa.

Hypercalcaemia would seem to be rare during immobilisation, whilst osteoporosis and hypercalciuria are constant. In fact, it often goes unnoticed. The case presented here confirms its predominance in the adolescent male. The reason for immobilisation seems to be irrelevant. The clinical symptoms are very variable: polydipsia, nausea, headache, apathy, anorexia. Blood calcium levels are raised, up to 14 mg%. This hypercalcaemia is due to very marked bone loss in adolescents, secondary to hyper-resorption and a temporary stoppage in osseous formation. The differential diagnosis from primary hyperparathyroidism is sometimes difficult but is aided by laboratory and histological findings. The essential is to consider the possibility of immobilisation hypercalcaemia in the presence of any suggestive symptoms in an immobilised adolescent. Treatment includes a return to weight bearing, adequate water intake and the administration of phosphorus, calcitonin, furosemide, and corticosteroids.

In a prospective study on digitalis intoxication, low serum magnesium was found in 90 patients, while 388 patients had values above 1.5 mEq/l. Hypomagnesemia was more frequent in women than in men, in those with low body weight and in those with advanced heart failure. More patients with hypomagnesemia than those without had nausea, anorexia, fatigue, flickering of vision and atrial tachycardia with block. Patients with hypomagnesemia also had lower serum potassium than normomagnesemic patients. There was, however, no significant difference in the prevalence of digitalis intoxication or in serum digitoxin concentration. Nor was there any correlation between serum digitoxin and serum magnesium levels.

The use of jejunum in conduit urinary diversion may lead to electrolyte disturbances, characterized by hyponatremia, hypochloremia, hyperkalemia, acidosis, and azotemia, and a clinical picture of nausea, vomiting, dehydration, anorexia, and lethargy. Four out of six patients deviated with a jejunal loop developed this syndrome, the cause of which is discussed. It is concluded that the use of jejunum in urinary diversion should be avoided.

A case of chlorpropamide-induced, symptomatic hyponatremia in a diabetic patient is reported. The hyponatremia was associated with loss of appetite, nausea, and vomiting. These symptoms caused reduced food intake which provoked severe hypoglycemia with disturbed consciousness. The hyponatremia developed when the chlorpropamide doses were increased from 400 to 600 mg/day. Withdrawal of chlorpropamide was followed by remission of hyponatremia. Chlorpropamide-induced hyponatremia is a rare complication and is due to an antidiuretic effect of chlorpropamide caused by increased secretion of adiuretin and potentiation of the effect of chlorpropamide caused by increased secretion of adiuretin and potentiation of the effect of adiuretin in the tubuli of the kidney. This case report and the analysis of 18 published cases in the literature show the following characteristics for chlorpropamide-induced hyponatremia: (1) Hyponatremia is a rare complication in the treatment of diabetics with chlorpropamide. The patients typically are female and over sixty. The dosage of chlorpropamide usually was 500 mg daily or even more. (2) Hyponatremia is often unrecognized for a long time because the symptoms are not specific. The characteristic symptoms include loss of appetite, nausea, vomiting, abdominal pain, confusional state and, rarely, convulsions and coma. Recovery occurs spontaneously after withdrawal of the drug. (3) The incidence of this type of hyponatremia is increased in cases of preexisting tendency to water retention such as heart failure and renal failure, and in cases of diuretic therapy. In the light of these findings, the authors believe that chlorpropamide is no longer a drug of choice in the treatment of diabetic women, especially in cases of preexisting tendency to water retention and in diuretic therapy. In such cases, a sulfonylurea without antidiuretic effect is to be preferred.

The serum digoxin concentration increased in 25 of 27 study patients (93%), and the mean serum digoxin concentration rose from 1.4 ng/ml to 3.2 ng/ml during quinidine therapy. Anorexia, nausea, or vomiting developed in 16 patients (59%) but disappeared in all ten patients for whom the digoxin dose alone was reduced, suggesting that digoxin excess caused these symptoms. Ventricular premature depolarizations developed in three patients after starting quinidine therapy; ventricular tachycardia developed in one patient, and another died suddenly. When starting quinidine therapy in patients who are taking digoxin, the clinical course, ECG, and serum digoxin level should be followed closely.

Interposition of the colon between the liver and diaphragm, ie. Chilaiditi's syndrome, visible during roentgenographic examination, has been described as an asymptomatic finding in adults of no clinical importance: it is occasionally symptom-producing in children. In mentally retarded adults, however, a unique syndrome commonly occurs, characterized by nausea, pain, vomiting, anorexia, distension, audible bowel sounds, and constipation: all are associated with three roentgenographic features of interposition. The symptoms respond to simple treatment and can be prevented by routine prophylactic measures.
