We reviewed the thirty cases of cytomegalovirus infections with occurred in previously healthy patients, hospitalised for fever from 1981 to 1992. Pregnant women, transplant recipients, HIV infected persons and all immunocompromised subjects were excluded. We observed 34 cases (18 women, 16 men) whose mean age was 34 years (17 to 79). Fever appeared progressively (73%), persisted more than 15 days (87%) and was well tolerated. The main functional symptoms were headaches, myalgia (53%), profuse sweat (50%), abdominal pain, diarrhea, recent loss of weight, dry cough (51%). Splenomegaly was present in 24% of the cases. Chest X ray was always normal. Differential blood count was always inverse and an authentic mononucleosis syndrome was present in 91%: it appeared mainly 13 days after onset of symptoms. Hepatic abnormalities were nearly constant, especially cytolytic (97%) (transaminases three or four times upper the normal limit) but also cholestatic (62%). Thrombopenia has been noticed once (48,000/mm3). Serological diagnosis was confirmed with Elisa test (anti CMV Ig M: 30 cases) or complement fixation test (seroconversion: one, significant increase of the titers: two). CMV viremia, studied in seven patients, was positive in three. Spontaneous or treated (NSAI in 30%) outcome was nearly always favourable (97%). Two patients presented severe complications: meningo encephalitis and spleen rupture. CMV infection in previously healthy patients has to be suspected, without waiting for the mononucleosis syndrome, in view of a prolonged, well tolerated febrile illness, without pharyngitis, associated with hyperlymphocytosis and mild cytolysis. A careful follow-up is needed to detect the rare but severe complications.

Some patients of dermatomyositis (DM) with interstitial pneumonia (IP) have common clinical features. Clinical features of these patients are acute onset, very poor prognosis and that patients have fever, arthritis, typical skin rash, mild myositis and show low ratio of CPK/LDH, low incidence of antinuclear antibody (ANA) appearance, low inflammatory signs. We experienced two cases of this category of DM with IP and examined immunological aspects. Case 1. A 52-year-old woman was admitted in June 1, 1990 with a one-month history of arthralgia and a ten-days history of fever, skin rash, myalgia and dyspnea on exertion. On examination she had Gottron's papules on her fingers, erythema on back, bilateral elbows and legs, proximal muscle weakness and arthritis. Fine crackles were audible in the lower lung fields. Laboratory data included CPK 200 IU/l, ALD 3.2 IU/l, LDH 805 IU/l. Analysis of bronchoalveolar lavage fluid (BALF) revealed increased cellularity with lymphocytosis. She was treated with oral corticosteroid (CS), pulse CS, cyclosporin A. Inspite of these therapies, she died of progressive respiratory insufficiency in July 10, 1990. Case 2. A 23-year-old woman was admitted in April 1, 1991, with a two-month history of arthralgia and a one-month history of fever, skin rash, stomatitis, alopecia. On examination she had Gottron's papules on her fingers, erythema on malar, bilateral elbows and legs, arthritis and stomatitis. Laboratory data included CPK 97 IU/l, ALD 8.5 IU/l, LDH 779 IU/l. She began experiencing dry cough and dyspnea on exertion in May 1991. Analysis of BALF revealed increased cellularity with lymphocytosis. She was treated with oral corticosteroid(CS), pulse CS, pulse cyclophosphamide.(ABSTRACT TRUNCATED AT 250 WORDS)

From 1982 to 1991, we experienced 76 patients with Mycoplasma pneumoniae pneumonia which were confirmed by serologic tests. There were 32 (42%) male and 44 (58%) female patients. One patient had underlying disease of diabetes mellitus while the other patients were in good health. The age ranged from 9 months old to 72 years old. All the patients complained of fever and coughing; 63% had dry cough and 37% had sputum production. Upper respiratory tract complaints such as rhinorrhea, sore throat, or earache were noted in 57% of the patients. Fifty-five percent of the patients had GI symptoms of anorexia, nausea, vomiting, or diarrhea. Other complaints included myalgia/arthralgia (29%), headache (30%), and general malaise (32%). Dyspnea (17%) and chest pain (20%) were occasional complaints. Seventy-one percent of the patients had WBC counts < 10000/cu mm and 29% > 10000/cu mm. The mean value of C-reactive protein (CRP) was 53.1 micrograms/ml, while 16% of the patients had a CRP value above 100 micrograms/ml. Thirty-one percent of the patients were noted to have a transient elevation of serum transaminase. Four different patterns of infiltration were seen in chest radiographic manifestation: 1) peribronchial and perivascular interstitial infiltrates (18.4%), 2) nonhomogeneous patchy consolidations (22.4%), 3) homogeneous acinar consolidations (27.6%), and 4) mixed interstitial and alveolar infiltrates (27.6%). Interstitial infiltration was more commonly seen in pediatric than adult patients (46% vs 20%). Other features of the radiologic manifestation were as follows: unilateral lesions in 80% of patients, single lobe lesions in 77%, lower lobe predominant in 69%, pleural effusion in 7%, and radiographic deterioration in 10%. Mycoplasmal pneumonia should be considered in the differential diagnosis of community-acquired pneumonias.

Ivermectin treatment was evaluated for its efficacy and side reactions in sixty patients of Orissa with Bancroftian filarial infection and microfilaremia. Ivermectin was administered as a single oral dose at four dosage levels (20, 50, 100 and 200 micrograms/kg), and both microfilarial clearance and associated side reactions were monitored in a double blind fashion. Blood microfilariae were cleared in all patients at all dosages within 1 to 14 days. In most patients microfilariae reappeared by third month. The microfilaria appearance by third and sixth month averaged 12.2 to 44 percent of pretreatment values in the four study groups. Side reactions were encountered in almost all patients, the commonest being fever, headache, weakness, myalgia and cough which occurred most prominently 12 to 72 hours after treatment. Side reactions were more frequent and severe in patients with high microfilaria counts. Clinical reaction scores for each group were independent of the dose administered. The 200 micrograms dose group showed significantly more rapid microfilariae clearance and its delayed reappearance as compared with the other dosage groups and without inducing significantly greater clinical reaction scores.

An outbreak of "humidifier fever" affected 16 (57%) of 28 workers in a print shop. The most common symptoms were myalgia, chills or subjective fever, and cough. Illness began 5-13 hours after entering the workplace, and lasted 2-24 hours. A humidifier in use the day of the outbreak was found to be contaminated with fungi, amebae, and Gram-negative bacteria. The risk of illness was highest for those who had been on the job 3 months before the outbreak, a time when the humidifier was in constant use. Serologic studies of print shop workers showed positive reactions to extracts of organisms isolated from the humidifier, but could neither distinguish ill from well workers, nor identify causative organisms. The presence of endotoxin-producing bacteria and the clinical syndrome are consistent with an organic dust toxic syndrome. Previous exposure appeared to be the major risk factor for illness.

Pneumonia is one manifestation of acute Q fever following infection with Coxiella burnetii. Fever, headache, and myalgia dominate the clinical picture of Q fever pneumonia. Cough is nonproductive and may be absent despite the presence of pneumonia. While in most instances pneumonia results in an illness of mild-to-moderate severity, on occasion it is rapidly progressive and results in respiratory failure. Infection occurs as a result of inhalation of contaminated aerosols. Infected cattle, sheep, and goats are the usual reservoirs for this zoonosis. In some areas, infected parturient cats serve as the reservoir, and in such instances, rounded opacities are seen on the chest radiograph. The diagnosis of C. burnetii pneumonia is usually confirmed by demonstration of a fourfold or greater rise in antibody titer. Treatment is usually with a tetracycline or rifampin for 7 to 10 days.

Legionella pneumophila is the cause of Legionnaires' disease, and Pontiac fever, an influenza-like condition without pneumonia. We present a case of Pontiac fever after exposure to a hot tub contaminated with L pneumophila. A 37 y/o wf presented to the office with acute onset of sore throat, fever, headache, and myalgia. Patient was hospitalized 3 days later because of worsening shortness of air. Chest x-ray was normal. Patient was treated with 2 days of IV erythromycin and was discharged home on oral erythromycin. Her Legionella IFA was 1:16,384. Two days later, she developed chest tightness, pleuritic chest pain, and increasing shortness of air but did not have any cough or sputum production. She was re-hospitalized with a diagnosis of Pontiac fever and treated with IV erythromycin plus oral rifampin. A repeat chest x-ray remained normal. After a detailed epidemiologic history was obtained, it was noted that she became ill after using a hot tub, which her two children also used and they themselves developed a self limited illness. Water from the hot tub was positive for L pneumophila by DFA, culture, and PCR. Patient improved gradually with therapy and was discharged home. This report emphasizes the importance of a complete epidemiologic history in the diagnosis of respiratory infections. It also demonstrates that aquatic environment can be contaminated with Legionella and serve as a source of infection.

A 2-year prospective audit on the profile and outcome of malaria cases admitted to a general hospital was performed. Fifty-six cases were seen from January 1991 to December 1992, 52 of which were due to monoinfections with Plasmodium vivax. The main presenting complaints were fever, chills, sweats, myalgia, dry cough and headache. A significant percentage had anaemia (64.3%), thrombocytopaenia (57.1%), hyponatraemia (42.9%), and liver dysfunction (44.7%). Diagnosis rests on the demonstration of parasites in stained peripheral blood smears. None of the patients developed major complications. A high index of suspicion of malaria must be maintained in the medical evaluation of all patients and in particular, of returning travellers.

Results from animal and preliminary human exposure studies have called into question whether the 5 mg/m3 8-hour time-weighted average threshold limit value (TLV) for zinc oxide fume is sufficient to protect workers against metal fume fever. The objectives of this study were to determine the clinical effects of exposures to low concentrations of zinc oxide and to ascertain whether these exposures elevated circulating levels of specific cytokines, which could account for the symptoms of the metal fume fever syndrome. Thirteen resting naive subjects inhaled, on separate days, air and 2.5 and 5 mg/m3 of furnace-generated zinc oxide fume for 2 hours. Subjects recorded symptoms and temperature and had blood drawn before and after each exposure. The mean (+/- SE) maximum rise in oral temperature at 6 to 12 hours after exposure was 1.4 +/- 0.3 degrees F after 5 mg/m3, compared with 0.6 +/- 0.5 degrees F after air exposure (P < 0.05). Mean temperature was also elevated after exposure to 2.5 mg/m3 zinc oxide (1.2 +/- 0.3 degrees F). In a parallel fashion, plasma levels of interleukin 6 (IL-6), a pyrogen, were significantly elevated after exposure to 5 mg/m3 zinc oxide. Mean IL-6 values (pg/mL) at pre-exposure and at 3 and 6 hours post-exposure were 1.9 (+/- 0.6), 2.8 (+/- 0.7), and 2.9 (+/- 0.6), respectively, on the air day and 1.6 (+/- 0.6), 4.4 (+/- 1.2), and 6.4 (+/- 1.1) on the 5 mg/m3 zinc oxide day. Zinc oxide exposure did not significantly affect plasma levels of tumor necrosis factor. Total symptom scores peaked 9 hours after the 5 mg/m3 zinc oxide exposure. Myalgias, cough, and fatigue were the predominant symptoms reported. Inhalation of zinc oxide for 2 hours at the current TLV of 5 mg/m3 produces fever and symptoms along with elevation in plasma IL-6 levels.
