Twenty-seven patients with serious gram-negative infections were treated with ticarcillin in an average daily dosage of 237 mg/kg (range, 174 to 307 mg/kg). Ticarcillin was bactericidal for all infecting organisms in concentrations ranging from 31.2 to 125 mug/ml. Five of 8 patients (62%) with overwhelming Pseudomonas pneumonia were cured or improved, and 9 of 12 (75%) were cured of pneumonia caused by other gram-negative organisms. Of six extrapulmonary infections caused by Pseudomonas, five (83%) were cured or improved. In seven cases, the infecting organism reisolated during therapy was more resistant to ticarcillin than the primary isolate. The serum half-life of ticarcillin in three patients with renal failure was 11.2 +/- 1.0 h, and during hemodialysis it decreased to 6.3 +/- 1.8 h. There were two episodes of superinfection with resistant organisms. Thirteen patients (48%) manifested eosinophilia, one of whom had severe urticaria. Prolongation of bleeding time was attributable to ticarcillin in two patients. Ticarcillin appears to be effective for therapy of serious gram-negative infections in dosages 30 to 50% less than those recommended for carbenicillin.

Pruritus is an important sign of localized or systemic disease and sometimes may be the only symptom of potentially fatal illness. Localized causes of pruritus include stasis dermatitis, atopic dermatitis, contact dermatitis, neurodermatitis and scabies. Generalized pruritus may be caused by environmental factors such as low humidity, skin diseases such as urticaria, or internal diseases such as biliary obstruction, renal failure, hematologic malignancy or acquired immunodeficiency syndrome. Therapy for pruritus depends on identification and treatment of the underlying cause. If no specific etiology is found, therapy is palliative. Avoidance of frequent bathing may be helpful, especially when xerosis plays a role. Topical emollients or short-term therapy with low-potency steroids may also be effective. Oral antihistamines provide nonspecific relief for many patients with intractable pruritus.

A 35-year-old woman had since early childhood suffered from recurrent urticaria-like rash, intermittent fever, arthralgia and pancochlear inner-ear deafness. At the age of 17 years she also developed a steroid-resistant nephrotic syndrome, found to be due to renal amyloidosis (type AA). The triad of renal amyloidosis, inner-ear deafness and recurrent urticaria is characteristic of Muckle-Wells syndrome, which has a hereditary basis. Rapidly progressive renal failure necessitated long-term haemodialysis and two renal transplantations. The accompanying immunosuppressive treatment with corticosteroids, azathioprin and, later, cyclophosphamide brought about a remission of the joint and skin abnormalities. After removal of the first donor kidney and termination of immunosuppressive treatment the syndrome recurred with subacute growth of an amyloid goitre as well as amyloidosis of the optic nerve. A few weeks before death a malignant non-Hodgkin lymphoma of the stomach was demonstrated. It was presumably a complication of long-term immunosuppression and not of the Muckle-Wells syndrome. The patient died of the complications of combination chemotherapy. Necropsy revealed generalized amyloidosis.

Clinical details and present day problems encountered in 425 cases of falciparum malaria (PF) are reported. 10.11% had taken chloroquine prior to reporting to us. Parasitic count done in 23.05% cases lacked correlation with severity of disease. Pattern of fever varied markedly but 5.4% were afebrile throughout and presented only with bodyache and malaise. Apyrexial spell was noted in 5.64%. 28.70% had typical facial looks of anaemia and sallow complexion. Cerebral symptoms were noted in 3.05%. Other symptoms were severe headache 33.4%, pain abdomen 3.29%, gastroenteritis 5.64%, jaundice 2.58% and bronchitis in 7.50%. We encountered subconjunctival haemorrhages with purpura and/or urticaria in four cases, symptoms suggestive of shock lung in 3, pulmonary oedema in 2, severe anaemia (HB less than 4 g%) in seven pregnant ladies, extrapyramidal symptoms in follow up period in 5 and congenital malaria in 2 cases. 83.25% were cured with chloroquine and oxytetracycline. 8.47% (who deteriorated despite the above treatment) were treated with quinine for 6 days. 5.17% (with severe disease) were also given quinine as first line drug. 2.82% (unresponsive to chloroquine and oxytetracycline but with mild disease) were treated with pyrimethamine-sulphamezathine combination for 5 days. One case who did not respond to quinine was treated with quinidine. Recrudescence was seen in 3.67% of patients treated with chloroquine and oxytetracycline. There was no case with renal failure, haemolysis due to G6PD deficiency and black water fever. There was only one death (0.23%) in our series. Self-medication, haphazard therapy and the slogan "Fever may be malaria-take chloroquine" can lead to problems in falciparum malaria.

To identify and measure the incidence of adverse effects of the angiotensin converting enzyme inhibitor enalapril 13,713 patients were studied for one year by prescription-event monitoring. Precise information about the duration of treatment was available for 12,543 patients. The frequency of many events was calculated, including dizziness (483 patients; 3.9%), persistent dry cough (360; 2.9%), headache (310; 2.5%) hypotension (218; 1.7%), and syncope (155; 1.2%). Less common reactions included angioedema, urticaria, and muscle cramps. Altogether 1098 (8%) patients died and the notes of 913 of them (83%) were obtained for detailed scrutiny. With the exception of a few patients with renal failure who deteriorated during treatment (reported on separately), no death was attributed to enalapril. Enalapril was considered to be effective, even in patients with advanced cardiac failure. These results for enalapril are reassuring and provide further evidence of the value of prescription-event monitoring.

Hormones of the thyroid gland (thyroxine, tri-iodothyronine) control the metabolism of cells and tissue of the body, while parathormone and calcitonine are balancing the intra- and extracellular levels of calcium and phosphorus by governing some metabolic functions of bones, kidney and small intestine. Growth, maturation and metabolic homeostasis of the organism depend, among other intrinsic factors, on a normal production and secretory rate of both thyroidal and parathyroidal hormones. Clinical conditions of hyperthyroidism induce 1. increased metabolic turnover of the body with transcutaneous heat loss, 2. disordered growth of hairs and nails, 3. hyperpigmentation of skin, 4. pruritus with or without urticaria. Pretibial (usually symmetrical) myxedema may be associated with conditions of either hyper- or hypothyroidism (e.g., Hashimoto's thyroiditis); if combined with bilateral exophthalmus and acropachyderma of fingers and toes, it is called Diamond syndrome, or E.M.O. syndrome. In hypothyroidism, the skin feels chilly and dry, looks pale, and may present follicular keratoses with or without secondary eczema. The hair appears dull and sparse due to disordered anagen phase. Skin wounds heal with delay. Diffuse myxedema originates in the papillary and periadnexal connective tissue and eventually extends to the dermis as a whole. Clinical conditions of hyperparathyroidism rarely cause secondary calcification of the skin; they may induce severe pruritus, particularly in secondary hyperparathyroidism due to renal failure. Impetigo herpetiformis or generalized pustular psoriasis, resp., may be set off by excessive surgical removal of the goiter. Congenital maldevelopment of both thymus and parathyroid gland leads to cellular immune deficiency with secondary chronic muco-cutaneous candidosis.

Urticaria may be the only cutaneous manifestation of a leukocytoclastic vasculitis. We have studied nine patients with urticarial vasculitis.The spectrum ranged from limited cutaneous disease (six cases) to severe systemic disease with renal failure (one case). The individual urticarial lesions were of long duration (over 4h) in all patients and in seven cases an ecchymotic stain was left when the urticaria resolved. All patients complained of moderate to severe pruritus. Associated findings included arthralgia (two cases), fever (one case) and glomerulonephritis (one case), but none had neurological disease, abdominal pain or arthritis. Therapy was difficult in seven patients, and these cases were controlled only with systemic corticosteroids. This disorder falls within the larger group of vasculitides. It is distinguished only by its skin lesions, which cannot always be distinguished clinically from common urticaria.

The therapeutic and biologic effects of murine monoclonal antibodies in patients with malignancies have been widely investigated. Attempts to enhance results by combining these agents with cytotoxic drugs are now under study. A Phase I trial was performed to assess the toxicity and biologic effects of escalating doses of R24 (0-40 mg/m2/day 1-5, 8-12), an antibody that binds to the ganglioside GD3 present on melanoma cells, administered in combination with cisplatin (120 mg/m2) and WR-2721 (740 mg/m2) on day 1. Twenty-three patients with metastatic malignant melanoma were treated and are evaluable. The true maximum tolerated dose of R24 given as part of this combination was not reached. The toxicity of the regimen was moderate and included fever and urticaria, which were attributed to R24. Severe but reversible renal failure was noted in six patients in subsequent (two or more) treatment cycles, but when cisplatin was administered in 3% saline, this toxicity was not seen. Responses were seen in 2 of 19 patients receiving all three agents and in 1 of 4 patients receiving only cisplatin and WR-2721. No significant enhancement of natural killer, lymphokine-activated killer, and antibody-dependent cellular cytotoxicity lytic activity or significant changes from baseline in lymphocyte subsets secondary to R24 were seen. In 4 of 10 patients tumor localization of mouse monoclonal antibody was found and appeared greatest at higher R24 doses and during week 1 of therapy. Human anti-mouse antibody responses developed by day 22 in 17 of 19 patients treated with R24, and the coadministration of cisplatin did not appear to abrogate this response. Finally, the half-life and Cmax of cisplatin were not affected by R24. In summary, the combination was well tolerated, responses were few, and significant biologic interactions or immunomodulation were not observed.

Even a single honeybee sting can lead to anaphylaxis in a susceptible person, but severe reactions can result from multiple stings, particularly if stings are from the fast-spreading Africanized honeybees, sometimes called "killer" bees. Signs and symptoms of multiple stings may include urticaria, nausea, vomiting, diarrhea, hypotension, confusion, seizures, and renal failure. Treatment is entirely supportive and requires special attention to airway patency, blood pressure, and renal function. Patients with more than 50 stings are at a higher risk of toxicity. Stingers should be removed by scraping gently to prevent further venom injection. Smoke or aerosolized deet (diethyl-toluamide) may thwart attacking bees, but avoidance is the best line of defense.

32 cases (21 acute severe malaria and 11 chronic malaria syndrome), who developed unusual complications and/or manifestations are reported. The acute manifestations were unexplained tachypnoea 4, pulmonary oedema 5 and shock due to multiple organ dysfunction syndrome 3, melena 2 and E coli septicaemia in one. The other features were concomitant salmonellosis 2, meningitis 1, renal failure 3, hepatorenal syndrome 2, hepatitis like illness 7, neck stiffness with normal CSF 3, urticaria and subconiunctival haemorrhage 2 each, apyrexial spell with anaemia 4, thromocytopenia 3, and hypoglycaemia 3 (two pretreatment and one while on quinine in 5% glucose drip). The chronic syndrome noted were hyperreactive malaria syndrome (Tropical splenomegaly) 3, repeated haemolysis 2, chronic simple malaria with positive parasitaemia and normal Igm levels 4, and cerebellar ataxia with tremors 3. Bone marrow in these cases was hypercullular with increase plasma cells. Liver biopsy revealed lymphocytic infiltration. There was no case with permanent neurogical deficit. All patients with pulmonary oedema and multiple organ dysfunction died but chronic syndrome patients recovered fully. Early recoginition of atypical manifestation and prompt treatment will decrease the mortality and morbidity due to malaria.
