Clinical symptoms and laboratory measures of renal and liver function, coagulation, and inflammatory parameters were prospectively studied in 74 hospitalized patients (14-74 years of age) with serologic evidence of nephropathia epidemica. The most common clinical findings were acute onset of symptoms, fever (greater than or equal to 38 degrees C), thirst, headache, nausea, back pain, vomiting, myalgia, and abdominal pain. Twenty-seven patients (37%) had hemorrhagic manifestations, i.e., epistaxis, melena, hematemesis, petechial bleeding, macroscopic hematuria, or metrorrhagia. Disseminated intravascular coagulation developed in four patients. Fifty-one percent had thrombocytopenia. Proteinuria was recorded for all patients, while hematuria and glucosuria were noted for 85% and 58%, respectively. Serum creatinine levels were elevated in 71 (96%) of the patients. Levels of C-reactive protein or erythrocyte sedimentation rates were elevated in all cases, usually to levels found in serious bacterial diseases. Sixty-six (89%) of the patients were followed for up to 7 months, at which time all had recovered clinically. No patient died or required dialysis. We conclude that nephropathia epidemica in Sweden has a clinical picture similar to that of hemorrhagic fevers in other parts of the world, but with a milder course and a better prognosis.

Between August 1982 and December 1985, seven patients at a children's hospital developed hospital-acquired pneumonia caused by Legionella pneumophila. Demographic data included the following: mean age 12.3 years (range 9 months to 20.5 years); male/female ratio 5:2; all patients were white. Some previously identified risk factors present in our patients included high-dose corticosteroid therapy (five patients), other immunosuppressive therapy (four), and chronic lung (five) or kidney (three) disease. Symptoms and signs included rapid onset, fever, cough, pleuritic chest pain, dyspnea, abdominal pain, diarrhea, and headache. Rhinitis, myalgia, and neurologic abnormalities were not noted. Chest roentgenograms revealed single-lobe consolidation in three patients, diffuse bilateral alveolar infiltrates in three, and pleural effusion in three. All patients were treated with erythromycin; three patients also received rifampin. Tracheal intubation and mechanical ventilation were required by four patients. Six patients improved after therapy. One child died of persistent lung disease 1 month after the onset of legionnaires disease. L. pneumophila was isolated from potable water in the hospital. Aerosol equipment cleansed with tap water and the showers were implicated as means of exposure by patients to contaminated potable water. No new nosocomial cases were seen after immunocompromised children were prohibited from taking showers, and sterile water was used to cleanse equipment for administering aerosol medications.

About 5 weeks after the beginning of the outbreak of Ebola virus fever in Yambuku, Zaire, several acute cases of the disease were observed. All of those affected had the following common signs and symptoms: sudden onset of high fever, with chills, headache, myalgia, anorexia, nausea, abdominal pain, sore throat, expressionless face, and profound prostration. In some cases, on around the fifth day of the acute phase, the appearance of an exanthematous rash on the trunk announced the hemorrhagic manifestations: hemorrhagic conjunctivitis, bleeding ulcerations in the mouth and on the lips, gingival bleeding, hematemesis, and melena; epistaxis, ear bleeding, hematuria, and postpartum hemorrhages were also reported. All these hemorrhagic cases had a fatal outcome within about a week. The hemorrhagic manifestations were less severe in the cases that occurred by the end of the outbreak than in the first reported cases. Hemorrhagic manifestations were less frequent and less severe, or even absent, in the nonfatal cases (convalescents, serologically confirmed). No biologic investigation of the hemostatic impairment could be performed under the emergency conditions of this field study.

Thirteen cases of hemorrhagic fever with renal syndrome (HFRS) have been observed in the Nancy area. Ten occurred during the summer of 1983 and three in April and May 1985. The clinical characteristics were in each case very typical: abrupt onset with high fever, myalgia, intense lumbar and abdominal pain, pulsatile headache, inflammatory syndrome, WBC count increase and thrombocytopenia. Acute renal failure occurred a few days later with oliguria (9 cases out of 13), massive proteinuria (9/13) and hematuria (6/13). All patients recovered without sequelae within 8-10 days. Renal biopsy performed in 8 patients showed slight tubular lesions with interstitial mononuclear cell infiltrate, congestion and diffuse interstitial edema, and in 2 cases hemorrhagic extravasation. No glomerular lesions were observed. Clinical, histological and epidemiological characteristics of these 13 French cases are highly similar to those of the Scandinavian Nephropathia Epidemica reports. The epidemiology of HFRS remains unclear as do its pathophysiological mechanisms.

An outbreak of unexplained illness occurred in members of an army reserve unit after field training in an area of New Jersey endemic for Lyme disease. Nine (12%) of the 74 who attended the exercise had serological evidence of Ehrlichia infection, defined as a single rise in titer of antibody to Ehrlichia canis greater than or equal to 1:160 four weeks after training. Two reservists with early serum samples had documented seroconversion, defined by a four-fold or greater increase in titer of antibody to E. canis, with a peak titer of greater than or equal to 1:160. Reservists with serological evidence of Ehrlichia infection were more than three times as likely to report arthralgia, myalgia, headache, appetite loss, nausea, eye pain, and abdominal pain than the other reservists. No reservist with serological evidence of Ehrlichia infection was hospitalized and most had minimal or no symptoms. This outbreak of ehrlichiosis suggests that the usual symptoms of Ehrlichia infection are milder than previously reported and that ehrlichiosis must be considered in symptomatic persons with recent tick exposure.

A 5-day continuous infusion of vincristine (VCR; total dose 4 mg/m2) has been given as part of a high-dose chemoradiotherapy regimen with bone marrow transplantation. Evidence of neurotoxicity, such as weakness, paraesthesia and intestinal hypomotility, was evaluated prospectively in nine patients. Five patients had advanced neuroblastoma and four, relapsed sarcomas, and all had responded to initial conventional-dose therapy. VCR was combined with high-dose melphalan (180 mg/m2) and fractionated total-body irradiation. Plasma concentrations of VCR were measured by radioimmunoassay during and up to 24 h after the infusion. Serum and urine electrolytes and liver function tests were measured during VCR treatment and at regular intervals thereafter. VCR concentration at 1 h ranged from 1.8 to 10.9 (median 6.6) ng/ml, and a steady state was achieved by 13-30 h (median 16 h). Levels above 1 ng/ml were maintained throughout the 5-day period with a mean steady-state concentration of 1.7 ng/ml (range 1.3-2.15). After cessation of the infusion, serum concentrations fell to below 0.25 ng/ml within 24 h. Abdominal pain occurred in one patient, but neither constipation nor ileus was seen. In two patients severe muscle pain occurred in the lower limbs towards the end of the infusion. Significant electrolyte problems did not occur and, in particular, there was no evidence of inappropriate ADH secretion. Transient increases in liver enzymes were common but bilirubin was not elevated during the period of monitoring. This regimen allows a two-fold escalation in the dose of VCR to be administered, producing sustained high serum drug levels without major toxicity.

We report the case of a 15-year-old girl who developed high fever, syncope, abdominal pain, nausea and vomiting, myalgia, pharyngitis, and a desquamating rash eight days after a diagnostic peritoneal lavage. The diagnostic peritoneal lavage wound was erythematous and tender. Incision of the site yielded 10 mL of exudate that cultured Staphylococcus aureus. The patient was treated with a first-generation cephalosporin and recovered without sequelae. To our knowledge, this is the first reported case of toxic shock syndrome following diagnostic peritoneal lavage.

Fifty-three workers in a battery factory, 52 solderers in a television factory, and 50 embroidery workers (a reference group) were studied. The average air lead levels of the three workplaces were 0.578 mg/m3, 0.002 mg/m3, and 0.001 mg/m3, respectively. Adverse effects in terms of clinical manifestations and biochemical criteria were evident among the battery factory workers. A significant dose-response relationship existed between the toxic effects and the air lead levels. The solderers showed no apparent abnormalities in comparison with the embroidery workers. The early clinical manifestations were dysfunction of the central nervous system, indigestion, arthralgia, and myalgia in the extremities. A positive association was observed between the prevalence of fatigue, mild abdominal pain, and arthralgia and the blood lead (PbB), urinary lead (PbU), and zinc protoporphyrin (ZPP) levels. The symptomatic threshold values of PbB, PbU, and ZPP were 30 micrograms/dl (1.5 mumol/l), 0.045 mg/l (0.2 mumol/l), and 40 micrograms/dl (0.7 mumol/l), respectively. The PbB, PbU, free erythrocyte protoporphyrin, and ZPP levels and the blood aminolevulinic dehydratase ratio could be used as indicators of lead exposure, although ZPP is preferred for a preventive monitoring program. The motor and sensory conduction velocities of the median nerve were slower in the exposed groups than in the reference group. No effects on behavioral function were observed among the solderers.

A 35-yr-old man with moderate hypertriglyceridemia, associated with a positive family history for hyperlipidemia, developed chylomicronemia with abdominal pain, muscle pain, and splenomegaly while being treated with cimetidine for a duodenal ulcer. The chylomicronemia and the pain subsided after the drug was stopped. When the patient was rechallenged with the drug 6 mo later, the chylomicronemia reappeared after a treatment period of 6 days. Chylomicronemia and its complications should therefore be considered as a potential risk when cimetidine is prescribed to patients with known hyperlipidemia.

In 1983, 949 cases of acute non-fatal illness consisting of headache, dizziness, blurred vision, abdominal pain, myalgia, and fainting occurred in the West Bank. Physical examination and biochemical tests were otherwise normal. There was no common exposure to food, drink, or agricultural chemicals among those affected. No toxins were consistently present in patients' blood or urine. Hydrogen sulphide gas was detected in low concentrations (40 parts per billion) at the site of the first outbreak. No other environmental toxins were found. The illness was thus of psychological origin and possibly triggered by the smell of hydrogen sulphide.
