Exogenous lipoid pneumonia is an uncommon medical condition resulting from aspiration or inhalation of oily material. Generally, lipoid pneumonia has nonspecific clinical and radiological presentations, and may be misdiagnosed as bacterial pneumonia or lung cancer. We describe an unusual case of exogenous lipoid pneumonia accompanied by peripheral blood and pulmonary eosinophilia. A 63-year-old man was admitted with progressively worsening exertional dyspnea and productive cough for 5 days. A chest radiograph showed abnormalities in the lower lobe of the right lung, and a diagnosis of community-acquired pneumonia was made; intravenous antibiotics were administered. However, dyspnea and hypoxia gradually worsened and peripheral blood eosinophilia developed. A bronchoscopy was performed and bronchoalveolar lavage fluid analysis showed markedly increased numbers of eosinophils (40%). Subsequently, a comprehensive review of history revealed that he fell asleep with camellia oil in his mouth for 2 weeks to relieve foreign body sensation of the throat. Sputum and bronchoalveolar lavage fluid cytology showed the presence of lipid-laden macrophages. He was diagnosed with lipoid pneumonia and acute eosinophilic pneumonia. Chest radiograph and symptom were rapidly improved after treatment with intravenous methylprednisolone.

Kikuchi disease, also called histiocytic necrotizing lymphadenitis, is an uncommon, idiopathic and generally self-limited disease, characterized by cervical lymphadenopathy. It can present systemic symptoms and signs, but ocular involvement is unusual. We report a 35-year-old woman who presented sudden decreased visual acuity and a swollen lymph node on the left side of her neck. On laboratory findings, there were no evidences of infection, autoimmune disease and systemic vasculitis. She was diagnosed with Kikuchi disease and bilateral retinal vasculitis by histologic analysis of lymph node, fundoscopy and fluorescein angiography.

Salmonella is a rare cause of psoas abscess and infectious spondylitis. We report a case of a 62-year-old male patient with Salmonella group D psoas abscess and infectious spondylitis as low back pain and subacute renal failure. The patient who had a previous operation history of abdominal aortic aneurysm rupture was admitted to evaluate low back pain and abnormal renal function. Bilateral psoas abscess and infectious spondylitis of lumbar vertebrae was detected by spine MRI and Salmonella group D was isolated in aspirated fluid of psoas abscess. After long term antibiotics treatment (ceftriazxone and ciprofloxacin), psoas abscess and spondylitis was markedly improved, however, his renal function was not recovered to progress to end stage renal disease.

Malignant rhabdoid tumor (MRT) is a rare but distinctive neoplasm of unknown histogenesis, occurring primarily in children. It has a characteristic histologic pattern and aggressive clinical behavior, and was originally thought to be a malignant sarcomatous variant of Wilms tumor; numerous cases of MRT arising from extrarenal sites have, however, been reported. We describe the radiologic findings of two cases of malignant extrarenal rhabdoid tumor that arose in the pelvic paravertebral region of two children. Both were confirmed by surgical excision and pathologic examination.

We report an unusual case of Plasmodium vivax malaria that occurred in a 22-year-old ankylosing spondylitis patient after initiating adalimumab therapy. P. falciparum malaria was initially included as a possible differential diagnosis due to hyperparasitemia and similar features in the peripheral blood smear. The patient was successfully treated with conventional therapy for P. vivax malaria.

Digoxin, also known as digitalis, is a purified cardiac glycoside extracted from the foxglove plant, Digitalis purpurea. Digoxin-mediated cardiac glycoside toxicity due to accidental plant ingestion can occur. Presently, a 69-year-old woman visited our emergency department with epigastric pain, nausea and vomiting after ingestion of a plant. Physical examination and initial laboratory blood test results were within normal limits. An electrocardiogram (ECG) showed sinus bradycardia with first degree AV block and diffuse ST-segment depressions in a "scooping" pattern. The plant was identified as D. purpurea, and the patient's serum digoxin level was 2.89 ng/mL. The patient was treated conservatively in the absence of any life-threatening event. Recovery was uneventful.

BACKGROUND: Mycobacterial identification in active pulmonary tuberculosis (APTB) is confirmative, even though successful rates using self-expectorated sputum are limited. Sputum specimens collected by hypertonic saline nebulization showed higher bacteriologic diagnostic sensitivities over those of self-expectoration, mostly studied in smear-negative or sputum-scarce patients. The efficacy of induced sputum was rarely assessed in real clinical settings. METHODS: A prospective randomized case-control study was performed in one hospital. The subjects highly suspicious of APTB were asked to provide 3 pairs of sputum specimens in 3 consecutive days. The first pairs of the specimens were obtained either by self-expectoration (ES) from the next day of the visit or sputum induction with 7% saline nebulization in clinic (SI), and the other specimens were collected in the same way. The samples were tested in microscopy, culture, and polymerase chain reaction (PCR). The outcomes of the bacteriological diagnosis were compared. RESULTS: Seventy six patients were assigned to either ES (38 subjects, median age of 51, 65.8% male) or SI (38 subjects, median age of 55, 52.6% male). APTB was clinically confirmed in 51 patients (70.8%), 27 in ES and 24 in SI. Among the APTB, more adequate specimens were collected from SI (41/65, 63.1%) than ES (34/80, 42.5%) (p=0.01). Bacteriological confirmation was achieved in 14 (58.3%) patients in SI, and 13 (48.1%) in ES (p=0.46). In the same-day bacteriological diagnosis with microscopy and PCR, there were positive results for 9 patients (37.5%) in SI and 7 patients (25.9%) in ES (p=0.37). CONCLUSION: Sputum induction improves sputum specimen adequacy. It may be useful for the same-day bacteriological diagnosis with microscopic examination and PCR.

Propionibacterium acnes is one of the commensals living on the human skin and glands, implicated mainly in acnes, but seldom in deep infection. Pleural empyema is rarely complicated with closed thoracostomy. We experienced 1 case of empyema caused by P. acnes after pleural biopsy and closed thoracostomy through a percutaneous pigtail catheter. A 79-year-old man was admitted for cough, purulent sputum and shortness of breath. Three weeks ago, closed thoracostomy and pleural biopsy were performed to confirm a diagnosis for his recurrent pleural effusion. He had increased amount of right pleural effusion. Through the pigtail catheter, pleural effusion was removed. Gram-positive rods were observed in Gram stain, but not cultured. By 16S rRNA analysis, P. acnes was confirmed as the pathogen. His empyema was repeatedly treated with antibiotics, fibrolysis and irrigation. Pleural decortication was recommended. We report the first case of empyema with P. acnes in Korea, possibly complicated with closed thoracostomy procedures.
