We report a case of an infected pneumatocele in the course of anaerobic pneumonia in an adult. To the best of our knowledge, anaerobic pneumonia complicated by a pneumatocele in an adult has not previously been described. The pneumatocele occurred on the fifth day of hospitalization, and rapidly increased in size, with the development of a subsequent mixed anaerobe infection. A pig-tail catheter was inserted and the pus drained. The bacterial culture from the pus was positive for three anaerobes: Bacteroid species, Peptostreptococcus asaccharolyticus and Fusobacterium species. Intravenous antibiotics and percutaneous catheter drainage resulted in a successful treatment.

4.Mycoplasma pneumonia associated with cerebral infarction in 3 children.
Chinese Journal of Pediatrics 2009;47(12):946-949
OBJECTIVETo study the clinical features and diagnostic methods of mycoplasma pneumonia complicated with cerebral infarction.
METHODData of 3 children with mycoplasma pneumonia who developed cerebral infarction, including clinical manifestations and imaging were collected, analyzed and the literature was reviewed.
RESULTAll the cases were pre-school or school-aged children, who developed the respiratory infection initially, the neurological symptoms were acute hemiparesis, with or without convulsion. The IgM antibody to Mycoplasma pneumoniae (Mp) was positive. Pulmonary imaging showed unilateral consolidation with atelectasis and pleural exudate. Neuroimaging showed occlusion of middle cerebral artery and infarction of its territory. After giving azithromycin, anti-coagulative and thrombolytic treatments, the neurological deficits recovered to some extent.
CONCLUSIONMycoplasma pneumonia were diagnosed based on respiratory symptoms and pulmonary imaging, the accompanied cerebral infarction was confirmed by neurological and neuroimaging findings.

Rothia mucilaginosa is a gram-positive coccus of the family Micrococcaceae. R. mucilaginosa is considered a part of the normal flora of the human oropharynx and upper respiratory tract and lower respiratory tract infections attributable to R. mucilaginosa are not frequent. We present a case of pneumonia, in which the R. mucilaginosa infection was diagnosed by quantitative cultures of a bronchoalveolar lavage (BAL) specimen. A 46-yr-old woman with B lymphoblastic lymphoma was admitted to the hospital for scheduled chemotherapy. Her chest computed tomography (CT) scan revealed bilateral multifocal nodular and patchy consolidation in both lungs. Investigation of the BAL specimen revealed that 7% of leukocytes had intracellular gram-positive cocci. The quantitative cultures of the BAL specimen grew mucoid, non-hemolytic, and grayish convex colonies on blood agar at a count of approximately 200,000 colony-forming units/mL. The colonies were identified as R. mucilaginosa. The patient was empirically treated with levofloxacin for 7 days, after which findings on the chest radiograph and CT scan improved. She was discharged with improvement on hospital day 46. To our knowledge, this is the first report of R. mucilaginosa pneumonia diagnosed in Korea. Quantitative culture of BAL specimen and examination of intracellular organisms are crucial for assessing the clinical significance of R. mucilaginosa recovered from the lower respiratory tract.

Pneumocystis carinii is a pulmonary pathogen of immunocompromised humans or other mammals. Its infection results from activation of organisms involved in latent infection or from new infection through the air. Almost all children are known to be infected within 2 to 4 years of birth, though prenatal transplacental transmission has not yet been demonstrated. In this study we observed experimental P. carinii infection in neonatal rats, thus investigating the possibility of transplacental vertical transmission by Diff-Quik staining of the lung impression smears and in-situ hybridization for lung sections. The positive rate of P. carinii infection in immunosuppressed maternal rats was 100%, but that in normal maternal rats was 0%. Cystic forms of P. carinii were observed in three of six 1-week old neonatal rats born of heavily infected mothers, but none of them was positive by in-situ hybridization. Five weeks after birth, cystic forms were detected in four neonatal rats. In the lobes of the lungs, no predilection site of P. carinii was recognized. Counts of cystic forms on smears and the reactivity of in-situ hybridization in the lungs of neonatal rats were significantly lower than in maternal rats. The present findings suggest that P. carinii is rarely transmitted through the placenta and proliferates less successfully in the lungs of neonatal rats than in mothers.

A 36-year-old homosexual Mexican man was admitted to our hospital, with a 30-day history of fever and headache. Upon cerebrospinal fluid examination, the patient's white blood cell count was 1,580/L, total protein was 26 mg/dL, sugar was 17 mg/dL, and his intracranial pressure was 23 cmH2O. The patient was diagnosed with HIV (Human Immunodeficiency Virus) infection by serum Western blotting. Cryptococcus neoformans was isolated in cultures of the patient's blood and cerebrospinal fluids. Chest computerized tomography revealed diffuse reticulonodular infiltration and a ground-glass appearance in both perihilar regions, suggestive of either Pneumocystis carinii pneumonia or cryptococcal pneumonia. On the patient's 6th day in our hospital, bronchoalveolar lavage and transbronchial lung biopsy were conducted via bronchoscopy, and a pathologic examination of lung biopsy specimens revealed signs of cryptococcal pneumonia. This patient died on his 14th day in our hospital, as the result of acute respiratory failure, associated with cryptococcal pneumonia and disseminated cryptococcosis.

Though the pathogenic significance and the reservoir of Ewingella americana have not been clarified, this organism has caused several pathogenic infections, especially in immunocompromised patients. We report a pneumonia in a patient with chronic renal failure, who had chronic rejection of transplanted kidney. E. americana was identified to be the pathogen of pneumonia with clinical symptoms and signs and radiological examination. As soon as he was treated with ceftriaxone and isepamicin, clinical improvement was followed with no further growth of E. americana or other pathogenic isolates from sputum culture. This suggests to be the case of pneumonia caused by E. americana for the first time in the Korean literature.

Metastatic pulmonary calcification refers to calcium deposition in the normal pulmonary parenchyma and this deposition is secondary to abnormal calcium metabolism. The most common radiologic manifestation consists of poorly-defined nodular opacities that are mainly seen in the upper lung zone. We present here a case of metastatic pulmonary calcification that manifested as atypical, dense, calcium deposition in airspaces within the previously existing consolidation in the bilateral lower lobes, and this process was accelerated by pneumonia-complicated sepsis in a patient with hypercalcemia that was due to hyperparathyroidism.
