A 53 year old man first presented with a mild anti-neutrophil cytoplasmic antibody (ANCA), type (MPO-ANCA) associated microscopic polyangiitis. Approximately one year later, he presented with fatigue, fever, cough, sore muscles and erythrocyturia. At admission he was uraemic. Kidney biopsy showed in LM extracapillary glomerulonephritis and in immunofluorescence microscopy linear deposition of IgG along the glomerular basement membrane (GBM). MPO-ANCA was still positive, but antibodies against GBM were now also present. Retrospective analysis revealed the presence of anti-GBM antibodies nine months before clinical illness. Pr3-ANCA (C-ANCA) was negative during the whole course. In spite of decreasing anti-GBM antibody levels during treatment, his condition aggravated, and he died from complications. Thus, coexisting anti-GBM antibodies may explain suddenly deteriorating renal function in patients with ANCA associated vasculitis.

In order to reduce the strain on the environment from the deposition of waste in landfills and combustion at incineration plants, several governments throughout the industrialized world have planned greatly increased recycling of domestic waste by the turn of the millennium. To implement the plans, new waste recycling facilities are to be built and the number of workers involved in waste sorting and recycling will increase steadily during the next decade. Several studies have reinforced the hypothesis that exposure to airborne microorganisms and the toxic products thereof are important factors causing a multitude of health problems among workers at waste sorting and recycling plants. Workers at transfer stations, landfills and incineration plants may experience an increased risk of pulmonary disorders and gastrointestinal problems. High concentrations of total airborne dust, bacteria, faecal coliform bacteria and fungal spores have been reported. The concentrations are considered to be sufficiently high to cause adverse health effects. In addition, a high incidence of lower back injuries, probably due to heavy lifting during work, has been reported among workers at landfills and incineration plants. Workers involved in manual sorting of unseparated domestic waste, as well as workers at compost plants experience more or less frequent symptoms of organic dust toxic syndrome (ODTS) (cough, chest-tightness, dyspnoea, influenza-like symptoms such as chills, fever, muscle ache, joint pain, fatigue and headache), gastrointestinal problems such as nausea and diarrhoea, irritation of the skin, eye and mucous membranes of the nose and upper airways, etc. In addition cases of severe occupational pulmonary diseases (asthma, alveolitis, bronchitis) have been reported. Manual sorting of unseparated domestic waste may be associated with exposures to large quantities of airborne bacteria and endotoxin. Several work functions in compost plants can result in very high exposure to airborne fungal spores and thermophilic actinomycetes. At plants sorting separated domestic waste, e.g. the combustible fraction of waste composed of paper, cardboard and plastics, the workers may have an increased risk of gastrointestinal symptoms and irritation of the eyes and skin. At such plants the bioaerosol exposure levels are in general low, but at some work tasks, e.g. manual sorting and work near the balers, exposure levels may occasionally be high enough to be potentially harmful. Workers handling the source-sorted paper or cardboard fraction do not appear to have an elevated risk of occupational health problems related to bioaerosol exposure, and the bioaerosol exposure is generally low.(ABSTRACT TRUNCATED AT 400 WORDS)

Six auto parts manufacturing workers were referred for evaluation of a 6-week history of work-related dyspnea, cough, and fatigue. Two workers also reported fever and weight loss. All six worked in a machining area where a waterbased metalworking fluid was used and recirculated under high pressure, thereby creating an aerosol. Chest radiographs revealed pulmonary interstitial infiltrates in four workers. Lung function tests showed that four workers had decreased diffusing capacity. After removal from the work area, all workers recovered. The metalworking fluid was cultured for bacteria and fungi. Isolates from broth cultures were sonicated to obtain antigen extracts. Serum precipitins to one or more of the microbial isolates were identified in all six workers but not in eight of nine nonexposed control subjects. The most frequent precipitin response (six of six workers) was against antigens of Pseudomonas fluorescens, which was cultured from the metalworking fluid. In all workers, precipitins to at least one other cultured organism were detected; these included Aspergillus niger, Staphylococcus capitas, an acid-fast Rhodococcus sp, and Bacillus pumilus. This represents the first report of hypersensitivity pneumonitis associated with industrial exposure to aerosolized metalworking fluid. Observed precipitin responses to a variety of microbial contaminants in metalworking fluid strongly suggest a causative role for microbial antigens in the induction and elicitation of this manifestation of hypersensitivity pneumonitis.

A multicenter, randomized, double-blind trial compared the safety and efficacy of the dihydropyridine isradipine with the angiotensin-converting enzyme (ACE) inhibitor enalapril given twice daily for mild hypertension. 160 patients received either isradipine (starting at 1.25 mg twice daily) or enalapril (starting at 2.5 mg twice daily) for 10 weeks. The dosage was increased if the average sitting diastolic blood pressure was > 90 mm Hg. Significantly greater mean reductions in systolic blood pressure were seen after 2, 6, and 8 weeks of isradipine. However, by the end of the trial, 83% of patients receiving isradipine and 78% receiving enalapril showed a decrease of at least 5 mm Hg in sitting diastolic blood pressure to a level below 96 mm Hg. Possible or probable drug-related adverse effects were reported in 36% of patients showing a good antihypertensive response to isradipine, and in 30% of those who responded to enalapril. There was a trend for a lower frequency of adverse effects in isradipine non-responders (25%) and a higher frequency in enalapril non-responders (43%). Pruritus, dizziness, edema, and fatigue were reported more often with isradipine, and cough and changed bowel habits were more common with enalapril. The relationship between the pattern of adverse effects and the extent of blood pressure reduction may be dependent on the mechanism of action of a drug. In responders, isradipine and enalapril showed differing patterns, but a similar overall incidence of adverse effects.

The efficacy and safety of cilazapril in chronic heart failure have been extensively investigated in an international clinical program in patients with underlying chronic heart failure with ischemic heart disease or dilated cardiomyopathy. Cilazapril in single doses of 1.25-5 mg produced a significant dose-dependent reduction in pulmonary capillary wedge pressure and systemic vascular resistance and a significant increase in cardiac index. In placebo-controlled studies, 1-5 mg of cilazapril once daily for 12 weeks prolonged predose exercise test duration and improved New York Heart Association classification status and signs and symptoms of chronic heart failure, including paroxysmal nocturnal dyspnea. Up to 86% of patients receiving these dosages had improvement, with only 12% of patients requiring the higher dose, 5 mg. These data indicate that cilazapril is effective when administered once daily to patients with chronic heart failure receiving concomitant therapy with digitalis and/or a diuretic. The safety of cilazapril in patients with chronic heart failure has been evaluated in 1,163 patients administered from 0.5 to 15 mg once daily for treatment periods ranging from 1 day to 57 months. Cilazapril was administered to 500 patients for at least 6 months, 264 patients for at least 1 year, and 101 patients for at least 2 years. The most frequently occurring adverse events were dizziness, coughing, dyspnea, fatigue, angina pectoris, and headache. Cilazapril was equally well tolerated by young and elderly patients. Treatment was discontinued due to adverse events in 12.9% of patients, mainly as a result of coughing (1.7%) and dizziness (1%). Forty-four patients (3.8%) died during cilazapril therapy or during a period without treatment. Of these deaths, 93% were due to cardiac causes, especially rhythm disturbances.(ABSTRACT TRUNCATED AT 250 WORDS)

This report presents data on the safety and tolerability of losartan potassium (losartan), a selective antagonist of the angiotensin II AT-1 receptor, in approximately 2,900 hypertensive patients treated in double-blind clinical trials. In these studies, headache (14.1%), upper respiratory infection (6.5%), dizziness (14.1%), asthenia/fatigue (3.8%), and cough (3.1%) were the clinical adverse experiences most often reported in patients treated with losartan. These adverse experiences were also frequently reported in patients receiving placebo: 17.2%, 5.6%, 2.4%, 3.9%, and 2.6%, respectively. Dry cough as an adverse event was reported in 8.8% of patients treated with angiotensin-converting enzyme inhibitors, and in 3.1% and 2.6% of patients treated with losartan or placebo, respectively. Only dizziness was considered "drug-related" more often in losartan-treated (2.4%) than placebo-treated (1.3%) patients. In controlled clinical trials, losartan was better tolerated than other antihypertensive agents as determined by the incidence of patients reporting any drug-related adverse experiences. Rates of discontinuation due to clinical adverse experiences in patients who received losartan monotherapy or losartan+hydrochlorothiazide were 2.3% and 2.8%, respectively, compared with placebo (3.7%). No laboratory adverse experiences were unexpected or of clinical importance. First-dose hypotension rarely occurred with losartan or with losartan plus hydrochlorothiazide, and withdrawal effects such as rebound hypertension were not observed in clinical trials. There were no clinically important differences in the clinical or laboratory safety profiles in the demographic subgroups for age, gender, or race. In controlled clinical trials, losartan demonstrated an excellent tolerability profile.

The objective of this study was to evaluate the reliability and validity of a brief index to measure symptoms in individuals infected with human immunodeficiency virus (HIV). From an ambulatory clinic that specializes in the care of HIV-infected individuals at a university hospital in northeast Ohio, 148 randomly selected outpatients (predominantly homosexual men) with a broad spectrum of HIV disease were enrolled in a prospective, cohort study. In standard interviews, patients rated the frequency of 36 symptoms related to HIV infection on an ordinal scale from zero (never) to three (daily); these interviews were repeated and outcomes determined every 3 months for one year. Clinical data were abstracted from the medical record with a standard chart review. Using specific criteria, 12 symptoms were selected for the HIV Symptom Index: fatigue, fevers, headache, imbalance, paresthesias, memory loss, cough, nausea, diarrhea, sadness, sleep disturbance, and skin problems. The HIV Symptom score (the sum of frequency ratings for the 12 symptoms) ranged from 0 to 31 with a mean of 9.4 (+/- SD 6.6). The test-retest reliability was high (intraclass correlation coefficient = 0.92) as was the internal consistency (Cronbach's alpha = 0.79). The validity of the index was established with three observations. (1) The HIV Symptom Index makes clinical sense and includes a representative spectrum of symptoms of infection. (2) Symptom Index scores were greater in patients with more advanced disease and in patients who were functionally impaired. (3) The Index was responsive to changes in health as the disease progressed.(ABSTRACT TRUNCATED AT 250 WORDS)

A rare case of cardiogenic fibrosarcoma is reported. A 66 y.o. male with dyspnea, cough and fatigue was examined. B-mode echo, MRI, and angiography disclosed a large tumor in the left atrium. A large fibrosarcoma and 2 cm of the left atrial wall around the tumor pedicle were removed. The atrial defect and right lower pulmonary vein were repaired with a patch. Four months later, the tumor recurred in the right lung, mediastinum, and left atrium. The tumor, middle and lower lobes of the right lung, and part of the left atrial wall were excised. One year after the first operation, the patient died of air way obstruction due to another recurrence of the fibrosarcoma in the left lung, esophagus, and mediastinum. Cardiogenic fibrosarcoma invading outward for the mediastinal organs is rare.

Diesel exhaust is a common air pollutant and work exposure has been reported to cause discomfort and affect lung function. The aim of this study was to develop an experimental setup which would allow investigation of acute effects on symptoms and lung function in humans exposed to diluted diesel exhaust. Diluted diesel exhaust was fed from an idling lorry through heated tubes into an exposure chamber. During evaluations of the setup we found the size and the shape of the exhaust particles to appear unchanged during the transport from the tail pipe to the exposure chamber. The composition of the diesel exhaust expressed as the ratios CO/NO, total hydrocarbons/NO, particles/NO, NO2/NO, and formaldehyde/NO were almost constant at different dilutions. The concentrations of NO2 and particles in the exposure chamber showed no obvious gradients. New steady state concentrations in the exposure chamber were obtained within 5-7 min. In a separate experiment eight healthy nonsmoking subjects were exposed to diluted exhaust at a median steady state concentration of 1.6 ppm NO2 for the duration of 1 h in the exposure chamber. All subjects experienced unpleasant smell, eye irritation, and nasal irritation. Throat irritation, headache, dizziness, nausea, tiredness, and coughing were experienced by some subjects. Lung function was not found to be affected during the exposure. The experimental setup was found to be appropriate for creating different predetermined steady state concentrations in the exposure chamber of diluted exhaust from a continuously idling vehicle. The acute symptoms reported by the subjects were relatively similar to what patients reported at different workplaces.

Descriptions of coronary artery bypass graft (CABG) recovery experiences were elicited for development of a preparatory discharge information intervention. A convenience sample of 15 men and 5 women were interviewed about the concerns, emotions, and physical sensations they experienced after CABG and the actions they found most useful to manage the recovery at three time points: (a) discharge; (b) 2 days after discharge; and (c) 3 weeks after discharge. Concerns of subjects centered on pain management and return to independence in activities of daily living. Reports of negative emotions increased over the first month of recovery and included depression, anger, and anxiety. Subjects most frequently reported physical sensations associated with fatigue, chest incision, sleeping, leg incision, shoulder and neck muscles, and coughing. Descriptions of the CABG recovery experience provided data for development of discharge information, that focused on concrete experiences from the viewpoint of the person having CABG surgery and included orienting information about the onset, sequence, and duration of the experiences.
