Pneumococci remain the most important cause of bacterial pneumonia with a considerable morbidity and mortality. The characteristic features of pneumococcal pneumonia are fever, shivering, productive cough, and radiographic detection of an infiltrate. Penicillin is still the cornerstone of therapy for pneumococcal infections. With the HIV-epidemic and worldwide emergence of resistant strains particularly the invasive pneumococcal infections became a growing therapeutic problem.

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.

Pseudomonas aeruginosa is a common causative agent of septicemia in compromised host and the entry site of organism is most commonly the respiratory and genitourinary tract. P. aeruginosa septicemia is often associated with vesicular or pustular skin lesions, subcutaneous nodules, deep abscess, cellulites and bullae. We report a case of P. aeruginosa pneumonia with multiple pustular skin lesions on the chest and leg. A 77-year-old male was admitted to our hospital complaining of fever, productive cough and eruptions. Laboratory findings revealed a leucocytosis (14,830/microliter) and an elevated CRP (21.72 mg/dl). The chest radiograph and computed tomography revealed a fluid level in preexisting bullae and a consolidation shadow with multiple cavities in the right upper lobe and nodular shadow with cavity in the left lower lobe. P. aeruginosa strain was isolated from the bronchial lavage and pustule. Blood cultures were negative. Skin biopsy specimens showed histologically a dense infiltrate of neutrophils in the horny cell layer. He was diagnosed as Pseudomonas aeruginosa pneumonia complicated with multiple pustular skin lesions. He was treated with antimicrobial agents for 24 days and his clinical condition improved.

A 21-year-old man who had a history of intravenous drug addiction was admitted with complaints of high fever and a productive cough. Chest CT on admission showed multiple consolidations, and pneumonia was initially diagnosed and treated. Because echocardiography after admission showed vegetation, with no bacteriological findings, attached to the tricuspid valve, right-sided infective endocarditis was diagnosed. After antibiotic therapy was changed, his fever was reduced and the inflammatory findings were eliminated. In the western world, most cases of right-side infective endocarditis are caused by drug addicts, but in Japan, this disease is very rare. Right-side infective endocarditis in drug addicts causes a high rate of pulmonary complications, in particular, septic pulmonary embolism. Many drug addicts suffering from pulmonary complications may consult doctors, but if the latter are not well-informed about this disease, it may not be possible to give an accurate diagnosis or proper treatment.

A 65-year-old man was admitted to our hospital with a productive cough, fever, and dyspnea; his chest radiographs revealed diffuse nodular and ground-glass opacities. He had worked on a farm for 11 years. Six months earlier, he had presented with similar symptoms at another hospital, and was admitted with suspected atypical pneumonia. After treatment with antibiotics, his condition improved and he was discharged. Examination on admission to our hospital revealed markedly elevated serum KL-6 levels. Histological findings from specimens obtained by video-assisted thoracic surgical lung biopsy showed caseating and non-caseating epitheloid cell granuloma, lymphocyte infiltration, and alveolitis. Bacteriological tests for mycobacteria and fungi were all negative. Farmer's lung was diagnosed in accordance with the criteria for hypersensitive pneumonia. It is generally accepted that the distinguishing histological finding for Farmer's lung disease is non-caseating epitheloid cell granuloma, but in this case, caseous granuloma was also present.

The patient was a 64-year-old woman. She had complained of dyspnea during exercise, productive cough, and pyrexia for two months after treatment to reduce her body weight with a Chinese herbal medicine, bofu-tsusho-san. This symptom worsened gradually, and she was admitted to our hospital for the examination and therapy. Chest radiography and CT scanning on admission showed ground-glass-attenuation with partial consolidation. Replacement of the medicine with treatment with oxygen and few medications for two weeks, made her condition well. The result of DLST for the herbal medicine, Bofu-tsusho-san was negative, but we strongly think it induced pneumonitis. The Chinese herbs ogon and kanzo which are ingredients of bofu-tsusho-san, can cause drug-induced pneumonitis. In conclusion, care should be taken if side effects, hypersensitivity, lung disease, liver injury, or other morbid conditions arise during the use of herbal medicines, because these disorders may lead to serious illness.

A 67-year-old man with a history of chronic obstructive pulmonary disease (COPD) was admitted with acute progression of dyspnoea, productive cough, fever, elevated central venous pressure, oedema and liver enzyme abnormalities. Pneumonia with secondary right-sided congestive heart failure was considered. Additional abdominal ultrasound examination confirmed by a CT scan showed a mass in the inferior vena cava (VCI) extending into the right atrium. The central liver location and impaired haemostasis rendered liver biopsy impossible. An alternative approach was discussed and guided by two-dimensional transoesophageal electrocardiography accessing the right internal jugular vein, biopsies were taken from the atrial mass with histology suggesting the presence of a hepatocellular carcinoma as the cause of acute dyspnoea.

A 36-year-old male who had been in good health visited our hospital because of fever, productive cough and lobar pneumonia of the right lower lobe. Bronchoscopic examination revealed pulmonary cryptococcosis. After the initiation of fluconazole the pneumonia started to improve, however, it was aggravated after the discontinuation of fluconazole because of liver dysfunction induced by it. The pulmonary cryptococcosis improved by lobectomy of the right lower lobe. There have been few reports of lobar pneumonia caused by primary pulmonary cryptococcosis. We report this case with fourteen other cases of primary pulmonary cryptococcosis which have been experienced in our hospital.

The authors describe a case of 80-years old male hospitalized because of radiological and clinical signs suggestive of right-sided pneumonia. The main complaints of the patient were of productive cough with increasing amounts of watery sputum irregular fever up to 39 degrees C, progressive dyspnea, generalized weakness and loss of weight. Despite extensive use of antimicrobial and antituberculosis agents significant deterioration of patients general condition and the progression of X-ray picture were observed, inflammatory infiltration started to encompass the contralateral lung. Bronchial washing revealed the presence of atypical and neoplasmatic cells of adenous origin type. Since this finding contrasted with the pattern of radiological abnormality that did not show any tumor-like changes, another diagnostic approach was undertaken. Transthoracic fine needle aspiration biopsy revealed cells of non-small cell lung carcinoma. The diagnosis of bronchioalveolar carcinoma established on the basis of clinicoradiologic pattern was confirmed at autopsy. Increasing bronchorrhea was the most prominent symptom.
