We have compared risk factors for cavitary histoplasmosis in 62 patients with that manifestation of the infection and in 679 patients with other forms of histoplasmosis, and we have evaluated the clinical and laboratory findings in 45 patients with cavitary histoplasmosis who were cared for at the Indiana University Medical Center hospitals during two large histoplasmosis outbreaks. Chronic obstructive lung disease and old age were the strongest risk factors for cavitary histoplasmosis but male sex, white race and immunosuppression were also important in certain patient groups. Fever, sweats, weight loss, productive cough, anemia, lymphopenia, and alkaline phosphatase elevation were common findings. The patients were occasionally incorrectly treated for presumed class 3 tuberculosis. Cultures were positive in 58% of patients, with sputum samples providing the highest yield (61%). Histoplasmal serologic tests provided useful clues to the diagnosis, positive in over 90% of cases. About one-third of patients recovered spontaneously while another 35% improved following treatment. About 4% developed chronic untreated cavitary histoplasmosis characterized by clinical and roentgenographic exacerbations and remissions. Of the deaths in four patients with untreated disease, one was caused by disseminated histoplasmosis while three died of other causes. Ketoconazole appeared effective in three of seven patients while its effect in three additional patients was uncertain. Toxicity precluded completion of ketoconazole therapy in one patient. Only amphotericin B has been proven to be effective therapy for cavitary histoplasmosis.

Penicillium marneffei is endemic in Southeast Asia. Although Thailand is a country in this region, penicillosis marneffei was rare. It was found occasionally in immunocompromised patients. With the increasing incidence of HIV seropositivity penicillosis marneffei emerged as one of the major problems in HIV infected patients residing in Thailand. The common presenting signs were fever, anemia, hepatomegaly, lymphadenopathy. productive cough and a common skin manifestation as molluscum contagiosum-like lesions. The diseases should be considered in Thais and immunocompromised travelers with a history of visiting Thailand. Because the disease is potentially curable, prompt diagnosis and treatment will lead to better prognosis.

A 27-year old female from Nairobi was admitted to the medical wards of the Kenyatta National Hospital in May 1991. She presented with a 4-week history of productive cough, fever, weight loss, and night sweats. She acknowledged a history of contact with a patient known to have pulmonary tuberculosis. She has never received a blood transfusion. She was single and para 3 + 0. Examination revealed a sick patient, with moderate pallor, fever of 38 degrees Celsius, and who was wasted with moderate dehydration and oral thrush. There was no finger clubbing, lymphadenopathy, or pedal edema. Chest examination revealed bilateral basal pneumonia. The spleen was palpable 4 cm below the costal margin; the liver was not enlarged. The rest of the examination was normal. On admission, complete blood count showed a haemoglobin of 5.4 g/dl, total white cells were 12.5 x 10-9/L, with 82% polymorphonuclear cells and 18% lymphocytes, erythrocyte sedimentation rate (ESR) was 85 mm/hour, and platelet count was normal. The anemia was normocytic, normochromic, and no malaria parasites were seen. Urea and electrolytes and liver function tests were normal. Sputum showed no acid fast bacilli on Ziel-Neelson Stain. HIV-1 antibodies were positive by enzyme-linked immunosorbent assay (ELISA) and Western blot. Bone marrow aspirate revealed a hypercellular marrow with reversed M:E ration, dyserythropoesis, reticulum cell hyperplasia, plentiful golden yellow pigment, and clumps of Histoplasma capsulatum. Chest X-ray showed bilateral basal pneumonia. She was treated with antibiotics and intravenous fluids, but she remained febrile, her general condition progressively deteriorated, and she died a week after admission. Treatment for histoplasmosis had not been commenced, and no postmortem examination was carried out.

We report four human immunodeficiency virus (HIV)-infected patients (3 men and one woman, average age, 34.3 years) with pulmonary infection (two with pneumonia and two with lung abscess) caused by Rhodococcus equi. These patients, who presented with fever and productive cough, were admitted to Nakornping Hospital in northern Thailand. Chest roentgenograms showed pulmonary infiltration and/or cavitary lesions. Their conditions were poor because of severe anemia, and transfusion was necessary in three of the four patients. Before culture results were available, the etiologic microorganisms identified in sputum smears were gram-positive and acid-fast coccobacilli. One of the four patients had a mixed infection with R. equi and Salmonella enteritidis. The mean CD4 lymphocyte count in the three tested patients was 10/mm3 (CD4/CD8 ratio = 0.057). Four isolates of R. equi were sensitive to imipenem, minocycline, erythromycin, vancomycin, and ciprofloxacin (minimum inhibitory concentrations; MICs, <or=1.56 microg/ml), but resistant to most beta-lactam antibiotics. Two isolates were sensitive (MICs, 0.20 and 0.78 microg/ml) and two resistant (MICs 50 and >100 microg/ml) to rifampicin. Two patients were treated with erythromycin plus rifampicin, while the other two were treated with anti-tuberculous drugs. However, treatment was ineffective; three patients subsequently died because of respiratory failure, and one patient did not improve and was transferred to another hospital in her hometown.

We report a patient with myelodysplastic syndrome (MDS), refractory anaemia with excess blasts in transformation, in whom complete remission (CR) was achieved with the administration of granulocyte colony-stimulating factor (G-CSF). The 76-year-old patient was admitted to our hospital with a fever and a productive cough; a diagnosis of pneumonia was thus made. Following treatment with antibiotics, the patient's condition improved, and MDS was diagnosed from peripheral blood and bone marrow examinations after the patient recovered from the infection. The patient achieved a sustained haematological CR that was confirmed by morphological and flow cytometric examination after treatment with G-CSF alone, although chromosomal abnormalities persisted. According to the literature, in almost all patients with acute myeloid leukaemia or MDS who were reported to achieve CR by G-CSF, the course was associated with infection, although our case did not have this complication during the course of G-CSF therapy. We suggest that patients with G-CSF alone without infection can achieve CR and that this may be related to a differentiation effect of G-CSF based on persistent chromosomal abnormality in this case.

In Japan and other countries where tuberculosis is not so common, people who were once infected with tuberculosis are thought to rarely suffer from the disease again due to exogenous reinfection. We experienced a mass outbreak of tuberculosis with 27 patients (including the source of infection) at a nursing home for the elderly. Epidemiological investigation suggested that the source of infection was an 82-year-old woman resident. For about 2 years before this outbreak, she had complained of a productive cough. At the time of the diagnosis of tuberculosis, chest radiography revealed a cavitary lesion and a smear of her sputum revealed organisms rated as Gaffky No. 8. Sputum culture was also positive (++++). Of the 27 patients, 19 (including the source) underwent restriction fragment length polymorphism (RFLP) analysis of isolates from the sputum. Eighteen patients showed an identical RFLP pattern, indicating that the infection had arisen from one source. Out of all patients, the source case of infection, 9 others with the same RFLP pattern, and other 3 who did not undergo RFLP analysis were admitted to our hospital. In 12 patients (3 men and 9 women excluding the source case) aged 80.6 years (range: 67-89 years), chest radiography disclosed tuberculous lesions, and smears, the polymerase chain reaction, and culture of sputum demonstrated Mycobacterium tuberculosis. As the prevalence of tuberculosis infection in Japanese aged 80 years at the time of the mass outbreak (1995) was presumed to be about 80%, the disease seemed to be caused by exogenous reinfection in most of these patients. All of the patients had senile dementia and other complications, and they were bedridden and undernourished. Anemia, hypoalbuminemia and lymphocytopenia were also observed in most of the cases. Malnutrition due to these complications appeared to be a possible risk factor of tuberculosis caused by exogenous reinfection.

We report the case of a 33-years-girl with SCA and severe PH. She developed six month before admission, non productive cough and dyspnea. Physical examination at admission revealed shortness of breath and right heart ventricular failure. Electrocardiography showed sinus rhythm and an incomplete left bundle branch block. Chest roentgenography revealed cardiomegaly with cardiothoracic index at 0.66 and pulmonary infiltrates. Laboratory tests revealed an anemia with hemoglobin of 7.1 g/dl, white blood cell count of 12,500/mm, moderate renal failure (cretininemia = 178 mumol/l) and hypoxemia with oxygen pressure of 60 mmHg. Hemoglobin electrophoresis revealed on heterozygous SCA. Echocardiography revealed dilatation of right heart cavities and a systolic pulmonary artery pressure of 60 mmHg. A perfusion lung scintigraphy demonstrated multiple subsegmental perfusion defects. PH is a common complication of adult patients with SCA. Appropriate therapies and strategies for prevention of PH in SCA are unknown. Further research exploring therapies such as oxygen, nitric oxide, prostacyclin and hydroxyurea are indicated.

A 55-year-old male presented with asymptomatic nodules and plaques on his scalp and pubic region of 2 months' duration. He was having productive cough, haemoptysis, chest pain, anorexia and weight loss and receiving antitubercular treatment for these symptoms for last 3 months. Clinical diagnosis of cutaneous metastatic disease was made. Chest x-ray revealed multiple coin shaped shadows on both sides with pleural effusion. Routine investigations were normal except for anemia and hyperuricemia. Biopsy of skin nodules showed features of metastatic adenocarcinoma. Features and significance of cutaneous metastases are discussed.

We describe a 71-year-old man hospitalized for fever and productive cough. Laboratory investigation showed anemia, thrombocytopenia, elevated transaminases, hyponatremia, and hypoalbuminemia. Computerized tomography of the abdomen, thorax, and sinuses, echocardiography, and a gallium scan did not reveal the source of the fever. The patient remained febrile despite courses of piperacillin-tazobactam/azithromycin and ceftriaxone/vancomycin. A bone marrow biopsy showed fibrin ring granulomas, and 2 rickettsial serologic panels were positive for Rickettsia typhi infection and negative for Q fever. The patient was given doxycycline, and the fever resolved within 48 h. We propose that fibrin ring granulomas also occur in murine typhus.

A 17-year-old girl presented with a 3-day history of epistaxis, vaginal bleeding and petechiae over the lower extremities. The patient had been feeling unwell with productive cough, fever, chills, poor appetite and weight loss for 2 months. Laboratory findings revealed anemia and thrombocytopenia, whereas bone marrow examination was unremarkable. She was diagnosed as having idiopathic thrombocytopenic purpura (ITP) in association with active tuberculosis (TB). The patient was treated with intravenous immunoglobulin (IVIg) and corticosteroid along with anti-TB drugs. During the follow-up period there was no recurrence of thrombocytopenia or TB. It is important to consider TB in the differential diagnosis of ITP, particularly in high TB-burden areas.
