This article reports a case of needlestick transmission of human T-lymphotropic virus type III (HTLV-III) infection to a health care worker in the UK from a patient who was presumably infected while in Africa. The patient, a white woman who had lived in central southern Africa, presented at the hospital with general malaise, dry cough, and fever. Lung biopsy revealed Pneumocystis carinii pneumonia infection, and the patient was seropositive for HTLV-III infection with a titer of 260. The patient reported that she had been unwell for 2-3 years. She had none of the accepted risk factors for acquired immunodeficiency syndrome (AIDS), and neither she nor her husband had visited the US, the Caribbean, or Zaire. Serum from the husband was positive for HTLV-III antibodies at a titer of 450. Despite intensive management and treatment with pentamidine, the patient died. During management of this case, a nursing staff member sustained a needlestick injury to the finger while resheathing a hypodermic needle. A small amount of blood was probably injected. 13 days later, the health care worker developed a severe flu-like illness with sore throat, headache, myalgia, and facial neuralgia. A macular rash and generalized lymphadenopathy were also noted. Serum drawn 27 days after the incident was negative for anti-HTLV-III infection, but titers on days 49 and 57 were 12 and 24, respectively. This contrasts with experience in the US, where needlestick injuries in health care workers have not resulted in either disease or transmission. It is assumed that the patient acquired AIDS in Africa, and that the infection was transmitted heterosexually. This case raises the possibility of differences in infectivity and other characteristics between HTLV-III viruses of US and African origin.

A prospective study of cytomegalovirus (CMV) infections has been carried out in 28 renal graft recipients. The protocol called for frequent blood and urine sampling during the first year after transplantation, but death or graft loss caused earlier termination in nearly half the patients. In this material 5/7 (71%) susceptible patients developed primary infections and 20/21 experienced a secondary infection (95%). Viruria was detected in 79% and viremia in 43%. The type of blood cell responsible for the viremic phase was studied by separating the blood cells on a density gradient. The polymorphonuclear cell fraction was the most common source of virus but virus could also be recovered from the mononuclear cell fraction. As some samples that were freeze-thawed repeatedly never yielded virus, it would appear that viable cells are needed for virus isolation. In both primary and secondary infections isolation of CMV from blood cells often preceded the isolation of CMV from urine. Among variables tested for a possible relationship to the occurrence of CMV viremia the only one to display such an association was the time at which rejection episodes occurred. In 19/28 such episodes recorded in 19 patients there was a temporal relationship to viremia (p less than 0.03). Seven of the patients experienced clinical symptoms suggestive of CMV infection as fever, cough, myalgia, arthralgia, chest pain and pneumonia. Laboratory signs included elevated amino acid transferase levels, leukopenia and thrombocytopenia and a specific anti-CMV antibody response.

A 25-year-old man developed severe shortness of breath, constricting chest pressure, chest pain, cough and myalgia following acute exposure to a waterproofing aerosol that contained trichloroethane. He became febrile and developed a small area of atetectasis with significant hypoxemia. Recovery was complete within 36 hours. This experience suggests that casual use of a trichloroethane aerosol with a surface active agent can cause acute pulmonary toxicity. The mechanism of this injury is unknown.

The early clinical features, primary care, treatment and short-term prognosis in 15 cases of acute myocarditis where diagnostic confirmation was made by endomyocardial biopsy or autopsy were analyzed. Characteristically, idiopathic myocarditis of possible viral etiology revealed preceding symptoms which consisted of flu-like symptoms, i.e., fever, upper respiratory infection (sore throat, cough), myalgia or arthralgia, general malaise, and gastrointestinal disorders (vomiting, anorexia, nausea, abdominal pain and soft stool). A severe cardiac or generalized disease condition may follow. Depending upon the progress of intensive medical and cardiac care, the patients' prognosis is not always poor. Diagnostic criteria based upon our own experience have been constructed as a proposal.

Since August, 1978, an epidemic characterised by respiratory symptoms and fever spread rapidly in a restricted area near Tampere, Finland. Four months later over half of the adult population reported intermittent or constant symptoms. The most frequent symptoms were cough, dyspnoea, chills, fever, headaches, muscle pain and aching of joints. The symptoms appeared to be associated with exposure to water vapour derived from tap water. Consequently this disease, which resembled extrinsic allergic alveolitis, was given the name 'bathing fever' for lack of any prevailing diagnosis. In clinical provocation tests lung diffusion capacity usually decreased, the leucocyte count increased, and a slight rise in body temperature was observed. Despite many efforts the specific causative agent in the tap water has not been identified. Neither massive chlorination of the water nor changing the sand filter of the water-works had any significant effect on the quality of the water. Therefore the source of water supply was changed in April, 1979. The symptoms have subsequently disappeared. Present knowledge about bathing fever suggests that, though rare, it may be typical of the Scandinavian type of climate.

We reviewed retrospectively the clinical records of 30 cases of sporadic Legionella pneumophila infection that occurred in Iowa between FY 1972 and 1978. Cases occurred throughout the year, most between May and December. Twenty-one male patients and 9 female patients ranging in age from 5-80 years were infected. Half the patients smoked or had an underlying illness; five were receiving corticosteroids or immunosuppressive therapy. Occupations and exposures related to hospitals, construction and travel were common; four patients had been exposed to birds. In addition to L. pneumophila infection, six patients had evidence of infection with a viral, mycoplasmal, bacterial, mycobacterial or fungal pathogen; three had had preceding dental infections. Twenty-seven cases were pneumonias visible on radiographs. Fever, cough, chills, myalgia and rales occurred inover half the cases. Headache, gastrointestinal symptoms and encephalopathy also were seen. Upper respiratory symptoms were uncommon. Urinalysis and blood studies often suggested renal and hepatic involvement, but other routine laboratory diagnostic tests were not helpful. All but two patients were hospitalized; seven required intensive care. The median duration of hospitalization was 12 days. Two patients who did not receive erythromycin or tetracycline therapy died.

The atypical measles syndrome is a relatively new disease that was first recognized 15 years ago. Initially, it occurred in children who were exposed to wild measles virus several years after they were immunized with killed measles vaccine. It was characterized by a two- to three-day prodrome of high fever, cough, headache, and myalgia followed by a rash that resembled Rocky Mountain spotted fever, scarlet fever, or varicella and associated with roentgenographic evidence of pneumonia with or without pleural effusion. This report highlights three unusual manifestations of this syndrome: 1) transient hepatitis, 2) persistence of pulmonary lesions for several years, and 3) occurrence of excessively high measles hemagglutination-inhibition antibody titers. Today, this syndrome occurs predominantly in adolescents and young adults.

Histoplasmosis is known to be endemic in various parts of the world, especially in North and Latin America. In Japan, Histoplasma capsulatum has rarely been isolated from the natural environment. To date, only seven cases of histoplasmosis have been reported in Japan including some that were contracted in foreign countries. Herein, we report the occurrence of acute histoplasmosis among Japanese travelers who were exposed to bat guano in a cave near Manaus, Brazil. A group of 8 Japanese travelers entered a cave for a total of 2 hours in March, 1993. All the visitors had been healthy and had no history of abnormal chest roentgenograms. From 10 to 20 days after the exposure, 7 (87.5%) of the 8 individuals developed abnormal symptoms including fever, malaise, loss of appetite, myalgia, arthralgia, chest pain and dry cough. Five (62.5%) had nodular infiltrative shadows with or without hilar lymphadenopathy in the chest roentgenograms. Eight (100%) of the individuals showed serologic evidence of histoplasmosis. Despite the small number of subjects, this high rate of infection may be related to the fact that the subjects stayed in an enclosed area where air exchange was minimal, at the end of a deep cave infested with numerous bats. The cave involved has never been documented as being endemic for histoplasmosis. The threat of H. capsulatum infection in bat-inhabited caves should be emphasized to travelers and also to physicians.

Side reactions following ivermectin treatment were evaluated in sixty males with high density bancroftian microfilaremia (GM 1388/ml). Following a single oral dose of ivermectin of different strengths (20, 50, 100 or 200 micrograms/kg), microfilariae clearance and side reactions were monitored in a double blind fashion. Microfilaria levels fell rapidly after ivermectin administration in all dosage groups and 98% of pretreatment microfilariae was cleared after 12 h of treatment. The rate of microfilaria (mf) clearance was slower with 20 micrograms/kg than with the highest dose (200 micrograms/kg) administered. Forty-six patients (77%) became amicrofilaraemic within 2 weeks of treatment. Side reactions were noted in 97% of cases. The most common reactions were fever, headache, weakness, myalgia and cough which appeared by 12 h and subsided by 72 h following treatment. The frequency and intensity of side reactions were related to pretreatment mf densities and were independent of the dose administered. Unusual side reactions were noted in a few patients with high density microfilaraemia. These included intense cough, shortness of breath, blood tinged mucoid expectoration associated with patchy pneumonitis of the lung. Itchy rashes, lymphatic nodules and raised alkaline phosphatase level were also observed in some patients. These side reactions were transient, self limiting and were not serious enough to warrant any treatment. These exaggerated unusual reactions were possibly due to allergic response of the susceptible host to rapid killing of large number of microfilariae.

Adenoviral pneumonia, while most common in infancy and young childhood, is rare in school childhood. Here, we report one case, a 13 years old otherwise healthy girl, suffered from fulminating pneumonia caused by adenovirus infection. She had dry cough, pharyngitis, lethargy, myalgia and fever in the beginning. Four days later, the patient became tachypneic, dyspneic and drowsy, and developed hypoxemia and diffuse bilateral infiltrates on chest radiographs. The laboratory data revealed elevated SGOT, CPK and LDH. Adenovirus was isolated from patient's endotracheal suction tube tips. Fortunately, weaning from mechanical ventilation was accomplished on the fifth day of hospitalization, despite of the high fatality rate of adenoviral pneumonia in this age group. The clinical characteristics and therapeutic management of our case are discussed and literatures reviewed.
