Influenza infection is a significant cause of morbidity and mortality in immunocompromised hosts, but its importance in adult cancer patients is largely undescribed. We therefore conducted a prospective study of the incidence and clinical features of influenza infection in patients with acute or chronic leukemia. The cohort, which consisted of all adult leukemia patients undergoing remission-induction chemotherapy during the 1991-1992 influenza epidemic, was followed prospectively for development of signs and symptoms of acute infection of the upper or lower respiratory tract. Of these 294 patients, 111 received chemotherapy as inpatients and 183 as outpatients. Throat swabs and nasal washes for viral culture were obtained from all symptomatic patients, who were then followed until all signs and symptoms resolved. Symptoms of respiratory tract infection developed in 37 leukemia patients (13%). Among these, influenza (A/Beijing/ H3N2) caused 3 (21%) of the 14 infections that developed during hospitalization but only 1 (4%) of the 23 that developed in the community (P = 0.14). Influenza patients presented with fever, rhinorrhea, nasal congestion, headache, and myalgia; those with other infections presented with signs and symptoms of lower respiratory tract infection (productive cough, rales, or rhonchi). Development of pneumonia was common in influenza patients, 1 of whom died from secondary fungal and gram-negative pneumonia. Influenza A virus infections accounted for a substantial portion of acute respiratory infections among adult leukemia patients during a community epidemic. Most infections appeared to be nosocomial and the most likely sources were visitors or hospital personnel. Immunization of household contacts and hospital staff may reduce the risk of influenza infection and its pulmonary complications in leukemia patients.

An outbreak of louse-borne relapsing fever, caused by the return to their original recruitment areas of soldiers at the end of 30 years of fighting in northern Ethiopia, was reported in the Arsi region. We studied 103 infants and children with louse-borne relapsing fever who were admitted to Asella Hospital between 1 May 1991 and 30 April 1992. Twenty-one per cent of the patients had a clear history of contact with sick ex-soldiers; 42% were students admitted to the hospital following the re-opening of schools after the summer vacation. The common clinical features of the disease were fever in 100%, headache in 84.5%, chills in 74%, abdominal pain in 51%, epistaxis in 20%, hepatomegaly in 26%, splenomegaly in 14%, petechial rash in 34% and jaundice in 10%. Differences in symptoms and signs according to age are described. Observed complications were pneumonia in 14% and central nervous system involvement in 10%. Four children went into deep coma, and two of them died. Severe disease was associated with a high density of spirochaetes in blood smears. Patients were treated with two low doses of penicillin or one dose of penicillin followed by, according to age, chloramphenicol or tetracycline, and with intravenous fluids. The case fatality rate was 1.9%. Jarisch-Herxheimer reactions occurred in 61% of patients. There were relapses in 2.9% of treated patients.

We report a case of pneumonitis induced by PL granules. A 45-year-old man took PL granules and other drugs for fever and headache. Because he subsequently developed high grade fever, cough and diarrhea, he was admitted to our hospital. His chest X-ray film revealed multiple patchy shadows in both lung fields. Analysis of bronchoalveolar lavage fluid (BALF) disclosed a high number of cells (total), lymphocytes, and a high CD4/CD8 ratio. Microscopic examination of transbronchial lung biopsy (TBLB) specimens showed infiltration of mononuclear cells and thickening of the alveolar wall. After discontinuation of drugs, his condition (symptoms, laboratory data, and chest X-ray findings) promptly improved. Lymphocyte stimulation tests (LST) for PL granules and acetaminophen were positive and an oral challenge test with PL granules was also positive. Based on these findings, we diagnosed this as a case of pneumonitis and enteritis due to PL granules. To our knowledge, this is the first reported case of pneumonitis due to PL granules.

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.

A 70-year-old retired fisherman presented with fever, chills and headache for four days. The clinical presentation was mild, including a self-limiting fever, pneumonia and elevated liver enzyme levels. Acute Q fever was proved by a four-fold rise of phase II IgG antibodies. Interestingly, the man denied any animal contact or travelling over the past year. This case may suggest that Q fever should be added to the list of differential diagnoses for acute febrile disease in Taiwan.

Nineteen patients with traumatic subdural hygroma (TSH) who were admitted between 1988 and 1992, were reviewed. Diagnosis of TSH was made by serial computerized tomography (CT) after initial head injury, and patients were followed for up to 19 months after head injury. The patients ranged in age from 53 to 91 years (mean 75.6 yrs). Fifteen patients were treated conservatively, and 4 patients underwent surgery. Patients had disturbance of consciousness (transient in 5 cases, persisting in 3 cases), headache (10 cases), vomiting (6 cases), and vertigo (2 cases). TSH began to develop within 24 hs in 10 patients after initial head injury, and in 13 (68%) of 19 patients, TSH was demonstrated within 72 hs after the initial head injury. Chronic subdural hematoma (CSH) developed in 5 (26%) of 19 patients and 2 patients underwent surgery. In 15 patients, who were treated conservatively, TSH disappeared in 10 patients, and decreased in 4 patients, but remained unchanged in 1 patient. Clinically, 11 patients improved. Three patients remained unchanged. One patient, who had cerebral contusion, died of pneumonia. In 4 patients, who underwent surgery, including 2 patients with CSH, TSH disappeared in all patients. Two patients improved, and 1 patient was unchanged. Another patient, who had cerebral contusion and normal pressure hydrocephalus, died. In general, clinical outcome was satisfactory, except for the patients who had accompanying parenchymal lesions before or after head injury. Surgical treatment was limited to the patients who had rapidly enlarging TSH and neurological deterioration.

We report a 44-year-old Japanese man with chronic meningitis due to coccidoiodomycosis. He was admitted to our hospital because of pneumonia after the business trip to Phoenix, Arizona. Coccidioid immitis was cultured from periathric abscess on the sternoclavicular joint. He became asymptomatic by 5-FC administration. One year later, however, he complained of headache and fever. Coccidiodial meningitis was diagnosed by cerebrospinal fluid (CSF) examination. Both systemic and intrathecal administration of miconazole and oral itraconazole were ineffective. While meningitis was not cured for three years, normal pressure hydrocephalus (NPH) developed. CSF cell count fell into normal range after administration of fluconazole (800 mg/day) for thirteen months, but NPH continued. This is the first report of coccidiodimycosis with CNS involvement in Japan.

Among 182 episodes with ARF (PaCO2 > 50 torr) in 400 episodes of COPD patients who were admitted to Chulalongkorn Hospital during the period 1982 to 1986, despite conservative treatment, 66 developed severe acute respiratory failure requiring assisted ventilation. Patients with a history of chronic cough, pneumonia as a precipitating factor and more severe ARF on admission, as indicated by palpitation, headache, cyanosis, alteration of consciousness, cor-pulmonale and decompensated acidosis (pH < 7.30), were likely to require mechanical ventilation. Indications for mechanical ventilation were carbon dioxide narcosis (43 episodes), severe hypoxemia despite on a high FIO2 (one episode), various combination parameters of respiratory muscle fatigue, cardiovascular instability (22 episodes). The major complications of mechanical ventilation were pneumonia, sepsis, pneumothorax, UGI bleeding of 16, 8, 5 and 9 episodes, respectively. The average duration of assisted ventilation and hospitalization were 15.8 and 19.02 days, respectively. The mortality rate was 50 per cent in the mechanical ventilation group compared with 9.8 per cent in the non-mechanical ventilation group. Increased mortality rate was found in those with pneumonia as the precipitating factor (68.4 vs 14.3%, respectively, in comparing the two groups). Complications of mechanical ventilation, which included pneumonia, sepsis, fluid overload, hyponatremia and persistent acidosis, were high-risk factors for the non-surviving group.

A 18-year-old woman presented to our hospital complaining of an acute onset of progressive dyspnea with nonproductive cough and high fever. The patient was in her usual good health until the previous day, when she started to develop symptoms 8 hours after taking aspirin for a headache. The chest roentgenogram revealed Kerley's lines (A and B), perivascular cuffing and hilar haze with bilateral pleural effusions. Body temperature was 38 degrees C and PaO2 was 48 torr. Infectious diseases and extrinsic allergic alveolitis were excluded. The lymphocyte stimulating test was negative for aspirin. Acute eosinophilic pneumonia was strongly suggested by bronchoalveolar lavage showing a marked increase in eosinophils without peripheral eosinophilia. By the seventh hospital day all clinical and radiographic signs were improved without steroid therapy. Most cases of acute eosinophilic pneumonia reported previously showed diffuse infiltrative shadows on the chest roentgenogram. The present case had interesting radiographic findings which suggested interstitial pulmonary edema.

A 47-year-old woman was thirdly admitted to our hospital for therapy to multi-drug resistant tuberculosis of the lung in June 88. Although she was treated with TH, PAS and EVM, M. tuberculosis were positive constantly in her sputum. She complained of sleep disturbance, irritability, headache on September 89, she was diagnosed reactive depression. But her symptoms were progressive, low level of intelligence test in November, apatic in December and became spastic paralysis and vegetable state at next year. She was died of pneumonia in November 90. Her autopsy findings showed no brain atrophy nor meningitis. Microscopically, central chromatolysis were showed in Betz cells and anterior horn cells, these findings sometimes suspected for Peragulla, but we could not obtained definite pathological diagnosis, because we could not have been obtained findings indicating for Peragulla. Finally, we reported the clinical course and autopsy findings of dementia occurred during therapy for multi-drug resistant pulmonary tuberculosis.
