Chloroquine is considered essentially nontoxic when used for the chemosuppression of malaria, but gastrointestinal upsets, headache, blurring of vision, pruritus, and uritcaria may occur during chloroquine therapy. Recently, Bhargava et al. and Eronini and Eronini have reported the extrapyramidal syndrome (EPS) following chloroquine therapy in adults. The clinical manifestations included upward rolling of the eyeballs, retraction of neck and back, trismus with marked difficulty in speech, and coarse tremors. Observations of 4 instances of EPS in children following chloroquine therapy for malaria are reported. A 2-1/2 year old girl was admitted to the All India Institute of Medical Sciences Hospital with a 4 day history of intermittent high grade pyrexia with chills and rigors. Following treatment with oral chloroquine in the recommended therapeutic dosage, the fever responded, but the child became drowsy and developed paroxysms of involuntary movements of the tongue, torticollis, torsion dystonia of the limbs, and parosysms of tonic muscular spasms. She completely recovered spontaneously within 48 hours. The 2nd case was that of a 12-year old female brought to the hospital with a 15-day history of intermittent high grade fever with chills and rigors. The patient was started on chloroquine sulfate in the recommended therapeutic dose. After an interval of 4 days she developed coarse tremors of the hands, upward rolling of the eyeballs, episodic deviation of the angle of the mouth towards the left, and trismus. These symptoms disappeared spontaneously within 8 hours. A 6-year old girl, the 3rd case, developed episodes of opisthotonous, upward rolling of the eyeballs, protrusions of the tongue, intermittent writhing movements of the upper limbs, and drowsiness following the ingestion of 6 tablets of chloroquine sulfate for suspected diagnosis of malaria. She spontaneously recovered from EPS over a period of about 48 hours. The 4th case, a 7-year old boy, gave a history of high grade fever with chills and rigors of 1 day's duration. He developed drowsiness, tonic spasms of the neck, upward rolling of the eyeballs, and writhing contortions of all limbs about 2 hours following intravenous administration of 100 mg of chloroquine. 8 hours later an additional 100 mg chloroquine was given intravenously for the mistaken diagnosis of cerebral malaria. On examination the child was drowsy, had generalized stiffness, torticollis, and trismus. He recovered gradually over a 48-hour period without any specific therapy. The exact mechanism of production of EPS remains uncertain.

Interleukin-1 (IL-1) plays a central role in the immune system, partly by stimulating the production of interleukin-2 (IL-2) and other cytokines by lymphocytes. In preclinical studies, recombinant interleukin-1 (rIL-1 beta) has shown antitumor activity. We conducted a phase II trial to evaluate the efficacy of rIL-1 in metastatic renal cell carcinoma (RCC). rIL-1 beta was given at a dose of 50 ng/kg i.v. daily for 5 days on a 28-day schedule. Nineteen patients were registered; 16 completed two cycles and were evaluable for response. There were no complete or partial responses to treatment. Toxicity was generally mild and typically involved grades I and II fever, rigors, hypotension, and weight gain. Severe neurologic toxicity was seen in two patients, grade IV seizures were seen in one, and grade III somnolence was seen in another. Analysis of soluble IL-2 receptor (sIL-2r) levels revealed an increase from a mean pretreatment level of 4,567 pg/ml to a mean of 6,124 pg/ml posttreatment (p < 0.001). The mean pretreatment IL-6 level was 51 pg/ml, increased to 84 pg/ml posttreatment (p < 0.05). Patients with bulky disease had higher sIL-2r levels, and patients with tumor fevers had higher IL-6 and sIL-2r levels than patients without fever did. A neutrophilic leukocytosis and a mild thrombocytosis were observed in response to rIL-1 beta administration. We conclude that rIL-1 beta in this dose and schedule is inactive in metastatic RCC.

The value of sulphonylureas in the long-term treatment of type II diabetes has been questioned. The potential benefits of an antidiabetic drug must be carefully weighed against the risk of developing hazardous adverse effects like hypoglycaemia. We present drug-induced hypoglycaemia in a 77-year-old Pakistani male who had hypertension, type II diabetes and renal parenchymal disease (grade I), presented to the emergency department complaining of a 1-day history of fever, loose motions and drowsiness. His fever was low grade, intermittent, and not associated with rigors and chills. He had four episodes of watery stools for 1 day, with no associated vomiting but with drowsiness. He was aphasic, unable to walk and did not recognize his family members. The patient was taken to his local doctor who found him to be hypoglycaemic, with a blood sugar of 45 mg/dl. He was managed with intravenous (IV) dextrose and referred to the hospital. Hypoglycaemia is perhaps the most widespread and underreported complication of oral hypoglycaemic agents and may lead to overwhelming morbidity and mortality. Patient evaluation and proper counselling may help in identifying patients at greatest risk and avoid complications associated with these commonly prescribed drugs.
