We introduce a rare case of gastric emphysema. A 68-year-old man presented with vomiting and dyspnea. Simple abdominal X-ray and CT showed marked dilatation of the stomach and abnormal intramural gas consistent with gastric emphysema. We performed gastric decompression via nasogastric tube drainage and parenteral nutritional support. Nine days after admission, the abnormal intramural gas had disappeared on follow-up CT. The acute gastric dilatation in this patient may have resulted from gastric hypomotility as a result of diabetic gastroparesis in addition to superior mesenteric artery syndrome resulting from malnutrition.

Although, erythema nodosum is a common skin manifestation associated with syphilis, nodular vasculitis is a rare feature. Here, we describe a case of a 22-year-old, human immunedeficiency virus negative, non-immunocompromised man who developed recurrent oral and scrotal ulcers with nodular lesions of the lower extremitie. Behcet's disease was initially suspected, however, his serologic test for syphilis was positive, and he was thus diagnosed with secondary syphilis, with a skin biopsy showing nodular vasculitis. The patient was treated with benzathine penicillin, and the skin lesions disappeared after treatment.

A 53-year-old woman had a 1.7 cm left adrenal mass on an abdominal computed tomography (CT) scan. She presented with paroxysmal headache, palpitation, sweating, and hypertension. The patient was highly suspected of having a pheochromocytoma, but measurements of 24-hour urinary metanephrine, catecholamines, and vanillylmandelic acid were normal. Plasma and urine catecholamine levels were within the normal range even during paroxysmal episodes. A scintigraphic study with 131I-metaiodobenzylguanidine (MIBG) revealed selective concentration of the radiotracer, corresponding to the CT mass. The patient underwent a left adrenalectomy and the pathological examination confirmed the diagnosis of pheochromocytoma. In this report, we describe a rare case of a symptomatic pheochromocytoma with normal catecholamine levels. Our case illustrates that routine nuclear scintigraphy, such as 131I-MIBG, should be performed even in cases with normal hormonal testing for all patients with high clinical suspicion of pheochromocytoma.

Human herpes virus-8 (HHV-8)-negative primary effusion lymphoma (PEL) is frequently observed in patients with chronic liver disease. We describe herein a case of PEL in a patient with chronic kidney disease. A 59-year-old woman presented with dyspnea. The patient had a history of uncontrolled pleural effusion. The pleural effusion revealed a malignant cell-dominant exudate. Serological tests were negative for human immunodeficiency virus (HIV). Initial chest and abdomen computed tomography showed bilateral pleural effusion; however, no evidence of a tumor mass or lymph node enlargement was found. A malignant lymphoma of diffuse large B-cell type was confirmed by pleural fluid cytology. Immunohistochemical staining of malignant cells was negative for HHV-8. She was treated with rituximab and CHOP (cyclophosphamide, adriamycin, vincristine, prednisolone) chemotherapy. We report a case of PEL in a patient with chronic kidney disease that may be a plausible predisposing factor for HHV-8-negative PEL.

BACKGROUND: Dipeptidyl peptidase 4 (DPP-4, also known as CD26) binds with adenosine deaminase (ADA) to activate T lymphocytes. Here, we investigated whether ADA activity is specifically affected by treatment with DPP-4 inhibitor (DPP4I) compared with other anti-diabetic agents. METHODS: Fasting ADA activity, in addition to various metabolic and biochemical parameters, were measured in 262 type 2 diabetes mellitus (T2DM) patients taking various anti-diabetic agents and in 46 non-diabetic control subjects. RESULTS: ADA activity was increased in T2DM patients compared with that in non-diabetic control subjects (mean+/-standard error, 23.1+/-0.6 U/L vs. 18.6+/-0.8 U/L; P<0.05). ADA activity was correlated with fasting plasma glucose (r=0.258, P<0.05), HbA1c (r=0.208, P<0.05), aspartate aminotransferase (r=0.325, P<0.05), and alanine aminotransferase (r=0.248, P<0.05). Compared with the well-controlled T2DM patients (HbA1c<7%), the poorly controlled group (HbA1c>9%) showed significantly increased ADA activity (21.1+/-0.8 U/L vs. 25.4+/-1.6 U/L; P<0.05). The effect of DPP4I on ADA activity in T2DM patients did not differ from those of other oral anti-diabetic agents or insulin. T2DM patients on metformin monotherapy showed a lower ADA activity (20.9+/-1.0 U/L vs. 28.1+/-2.8 U/L; P<0.05) compared with that of those on sulfonylurea monotherapy. CONCLUSION: Our results show that ADA activity is increased in T2DM patients compared to that in non-diabetic patients, is positively correlated with blood glucose level, and that DPP4I has no additional specific effect on ADA activity, except for a glycemic control- or HbA1c-dependent effect.

BACKGROUND/AIMS: The clinical implications of hypocholesterolemia have not been well studied, although some studies have revealed an association between hypocholesterolemia and intracerebral hemorrhage (ICH). We evaluated the clinical characteristics of subjects with very low-density lipoprotein cholesterol (LDL-C) and compared the risk for ICH using various clinical parameters. METHODS: Using hospital records, we evaluated the clinical characteristics of subjects with LDL-C levels < or = 40 mg/dL (very low LDL-C group). We also evaluated the risk for ICH in this very low LDL-C group and in subjects with low LDL-C < or = 70 mg/dL (low LDL-C group). RESULTS: Among 34,415 subjects who presented at the laboratory for serum LDL-C measurements, 250 subjects had a very low serum LDL-C level (< or = 40 mg/dL). About half of the subjects were statin users; the very low LDL levels in the other subjects were likely attributable to alcohol consumption or a various chronic illness such as liver disease or end-stage renal disease (ESRD). ICH occurred in three subjects with very low LDL-C, all of whom had no history of statin use. ESRD tended to be associated with ICH in subjects with serum LDL-C < or = 70 mg/dL. CONCLUSIONS: About 1% of the subjects whose LDL-C was measured in the hospital had a LDL-C level < or = 40 mg/dL, and about half of these subjects had no history of hypolipidemic therapy. ICH incidence was not related to LDL-C level or statin use.

Hemorrhagic fever with renal syndrome (HFRS) caused by the Hantann virus occurs frequently in Korea. On the other hand, the incidence of HFRS is very low in Jeju Island. A 62-year-old man was transferred from another hospital because of persistent fever, myalgia, generalized edema, epigastric pain, conjunctival injection, costovertebral angle tenderness, thrombocytopenia and azotemia. On the second hospital day, he exhibited oliguric symptoms. His urine output increased from the fourth hospital day. The test for the anti-Hantaan virus antibody was positive. Finally, he was diagnosed with HFRS and recovered with conservative management. HFRS should be considered when acute renal failure develops in patients with fever and thrombocytopenia in Jeju Island.

BACKGROUND: Nontuberculous mycobacteria (NTM) are ubiquitous in soil and water. Most NTM cause disease in humans only rarely unless some aspect of host defense is impaired. Recently, rapidly growing mycobacteria (RGM) is not uncommon, and the prevalence of RGM infection has been increasing. RGM causes a wide spectrum of pulmonary and extrapulmonary diseases and has been shown as an important source for opportunistic infection. MATERIALS AND METHODS: We report 5 patients of skin and soft tissue infection due to RGM in tertiary medical center in Jeju Island and analyzed 21 patients of skin and soft tissue infection due to RGM in Republic of Korea. Clinical, microbiological and epidemiological data were collected from each patient. NTM isolates were identified using conventional and molecular methods including 16S rDNA gene sequencing. RESULTS: The mean age of the RGM patients (n=26) was 54.9 +/- 15.9 years and 73% were women. Mycobacterium fortuitum complex was the most common (12/26). Antimicrobial resistance for clarithromycin and quinolone were 12% and 60%, respectively. Clarithromycin based therapy was done in 46%. The mean duration of treatment was 21.2 +/- 8.7 weeks. CONCLUSIONS: Many cases can be cured after therapy for 4-7 month with at least 2 or 3 antibiotics according to in vitro susceptibility. Recent increasing of NTM cases suggests that species and subspecies identification is epidemiologically important, especially related to medical procedure, and surgery.

The potential relationship between vitamin D (VitD) status and metabolic control in patients with type 2 diabetes mellitus (T2DM) warrants further study. We aimed to evaluate the relationship between the serum 25-hydroxyvitamin D [25(OH)D] level and various parameters in patients with T2DM. We analyzed retrospectively data from 276 Korean patients with T2DM whose serum 25(OH)D level was measured in our hospital. Nondiabetic healthy subjects who visited the hospital for health screening were selected as the control group (Non-DM, n=160). Compared with control subjects, patients with T2DM had a lower serum 25(OH)D level (15.4+/-0.5 vs. 12.9+/-0.4 ng/ml, p<0.01). Eleven percent of T2DM patients were VitD "insufficient" (20-29 ng/ml) and 87% of the patients were VitD "deficient" (<20 ng/ml). The serum 25(OH)D level was significantly related to serum fibrinogen, triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), ferritin, the urine albumin creatinine ratio, and hemoglobin A1C (HbA1C). In a multivariate logistic regression analysis, high levels of HbA1C, TG, and LDL-C were independently associated with VitD deficiency in T2DM patients. The results of the present study show that the majority of Koreans with T2DM are VitD deficient, and the serum 25(OH)D level in patients with T2DM is related to lipid and glucose parameters. Further studies are required of the relationship of VitD with fibrinogen and other related parameters.

Objectives: Rasmussen’s aneurysm may cause life-threatening hemoptysis. We investigated the clinical characteristics and outcomes of patients with hemoptysis and Rasmussen’s aneurysm. Methods: We retrospectively investigated patients who clinically presented with hemoptysis and were diagnosed with a Rasmussen’s aneurysm on spiral chest computed tomography (CT). Results: Our study included 16 patients (men:women, 12:4; mean age, 65.25 ± 13.0 years). Massive hemoptysis was observed in nine patients (56%) and blood-tinged sputum in four patients (25%). Ten patients (62.5%) had a history of pulmonary tuberculosis, and three patients (18.7%) had underlying lung cancer. Chest CT revealed coexisting fungal balls in seven patients (43.7%). Bronchial artery embolization (BAE) was performed in 12 patients (75%). One patient died of uncontrolled massive hemoptysis. Conclusions Patients with Rasmussen’s aneurysm showed hemoptysis during the course of the disease; however, bleeding can be controlled with conservative therapy and radiological interventions, such as BAE.
