Drug rash with eosinophilia and systemic symptoms (DRESS) syndrome is a rare and potentially fatal condition characterized by skin rash, fever, eosinophilia, and multiorgan involvement. Various drugs may be associated with this syndrome including carbamazepine, allopurinol, and sulfasalazine. Renal involvement in DRESS syndrome most commonly presents as acute kidney injury due to interstitial nephritis. An 11-year-old boy was referred to the Children's Hospital of Pusan National University because of persistent fever, rash, abdominal distension, generalized edema, lymphadenopathy, and eosinophilia. He previously received vancomycin and ceftriaxone for 10 days at another hospital. He developed acute kidney injury with nephrotic range proteinuria and hypocomplementemia. A subsequent renal biopsy indicated the presence of acute tubular necrosis (ATN) and late exudative phase of postinfectious glomerulonephritis (PIGN). Systemic symptoms and renal function improved with corticosteroid therapy after the discontinuation of vancomycin. Here, we describe a biopsy-proven case of severe ATN that manifested as a part of vancomycin-induced DRESS syndrome with coincident PIGN. It is important for clinicians to be aware of this syndrome due to its severity and potentially fatal nature.

Toxic megacolon is a rare clinical complication of fulminant Clostridium difficile infection. The mortality rate of fulminant C. difficile infection is reported to be as high as 50%. Fecal microbiota transplantation is a highly effective treatment in patients with recurrent or refractory C. difficile infection. However, there are few published articles on the use of such transplantation for fulminant C. difficile infection. Here, we report on a patient with toxic megacolon complicated by C. difficile infection who was treated successfully with fecal microbiota transplantation.

Pulmonary hypertension is a frequent complication of chronic obstructive pulmonary disease (COPD) and associated with a worse survival and increased risk of hospitalization for exacerbation of COPD. However, little information exists regarding the potential role of systemic inflammation in pulmonary hypertension of COPD. The purpose of the present study was to investigate the degree of C-reactive protein (CRP) and endothelin-1 (ET-1) levels in COPD patient with and without pulmonary hypertension. The levels of CRP and ET-1 were investigated in 58 COPD patient with pulmonary hypertension and 50 patients without pulmonary hypertension. Pulmonary hypertension was defined as a systolic pulmonary artery pressure (Ppa) > or =35 mmHg assessed by Doppler echocardiography. Plasma CRP and ET-1 levels were significantly higher in patients with pulmonary hypertension than in patients without hypertension. There were significant positive correlations between the plasma ET-1 level and CRP level in the whole study groups. For COPD patients, systolic Ppa correlated significantly with plasma CRP levels and plasma ET-1 levels. These findings support a possibility that CRP and ET-1 correlate to pulmonary hypertension in COPD patients.

BACKGROUND: The polymerase chain reaction (PCR) test is important for the confirmatory diagnosis of tuberculosis (TB) caused by Mycobacterium tuberculosis. The aim of this study was to analyze the yield of repeated PCR testing in patients with confirmed pulmonary TB. METHODS: The medical records of 130 patients, who had more than two consecutive PCR tests and a M. tuberculosis-positive sputum culture from August, 2006 to December, 2007, were retrospectively reviewed for the purposes of this study. A positive TB-PCR test was defined as at least one positive test result. RESULTS: The cumulative positive PCR test rate was 80% (104/130), with gradually increasing rates of positive findings upon the first, second and third TB-PCR tests with 52.3%, 68.5% and 75.4%, respectively. However, further testing did not increase the positive rate further. CONCLUSION: Repeated PCR testing at least three times for M. tuberculosis is helpful for diagnosis of pulmonary TB.

BACKGROUND AND OBJECTIVE: The purpose of this study was to identify clinical characteristics of secondary form of BPPV. MATERIALS AND METHODS:Of 384 patients with BPPV, 82 patients have a ipsilateral inner ear disease to the BPPV. We reviewed the site of lesion, duration of treatment in secondary BPPV and compared with idiopathic BPPV. RESULTS: The site of canal affected by idiopathic BPPV (M=119, F=183) showed that 138 (Lt=62, Rt=76) had a lateral canal, 157 (Lt=63, Rt=94) had a posterior canal, 7 had a multicanal. The involved canal by secondary BPPV (M=45, F=37) showed that 34 had a lateral canal, 43 in posterior canal, 1 in anterior canal and 4 in multicanal. 28 patients with idiopathic sudden sensory hearing loss developed BPPV within a few days (posterior=17, lateral=7, multicanal=4). 12 patients had a unilateral peripheral vestibulopathy and ipsilateral BPPV (posterior=11, lateral=1, anterior canal=1). 14 patients with meniere's disease developed ipsilateral BPPV (Lateral=9, posterior=5). 28 patients with BPPV had a history of headtrauma which is considered to be cause of BPPV. The mean duration of treatment is 2.68 on idiopathic BPPV, 6.27 on BPPV with ISSHL, 6.75 on BPPV with unilateral vestibulopathy, 2.28 on BPPV with meniere's disease and 2.4 on posttraumatic BPPV. There was no significant difference of recurrence among groups. CONCLUSION: Secondary BPPV showed different prevalence of involved canal from idiopathic BPPV. The duration of treatment for BPPV with ISSHL or unilateral vestibulopathy take longer time than for other groups.

Tracheal bronchus is an uncommon anomaly in which an ectopic bronchus originates directly from the supracarinal trachea. It is usually an asymptomatic anatomical variant incidentally found on computed tomography or bronchoscopy. However, it can present with symptoms, such as chronic cough, wheezing, atelectasis, and recurrent pneumonia. We report a case of tracheal bronchus diagnosed in the neonatal period, in which the term baby presented with respiratory distress and persistent pulmonary hypertension of the newborn after birth, but no other congenital anomaly was found on further evaluation.

PURPOSE: Chronic obstructive pulmonary disease (COPD) is characterized by chronic inflammation of the airways and progressive destruction of lung parenchyma. Apoptosis is critical for the maintenance of normal tissue homeostasis and is in equilibrium with proliferation and differentiation. This study was undertaken to investigate relationship between apoptosis of peripheral blood lymphocytes during exacerbation of COPD and inflammatory response that characterizes this condition. MATERIALS AND METHODS: Seventeen patients with COPD exacerbation, 21 stable COPD, and 12 control subjects were included. T lymphocytes were isolated from peripheral blood using MACS. Apoptosis of T lymphocytes was assessed with FACS using annexin V and 7-aminoactinomycin. Serum levels of interleukin (IL)-6, IL-8 and tumor necrosis factor (TNF)-alpha were determined by an immunoassay technique. RESULTS: There was significantly increased percentage of apoptotic lymphocytes, CD 4+, and CD 8+ T cells in the peripheral blood of patients with exacerbation of COPD compared with stable COPD. Serum levels of IL-6, IL-8, and TNF-alpha were significantly increased in patients with exacerbation of COPD compared with stable COPD. Only TNF-alpha presented a positive correlation with apoptotic lymphocytes in patients with exacerbation of COPD. CONCLUSION: Increased apoptotic lymphocytes may be associated with upregulation of TNF-alpha in the peripheral blood of patients with acute exacerbation of COPD.

Rectus sheath hematoma (RSH) is a rare condition caused by hemorrhage into the rectus sheath. It is usually associated with severe cough, abdominal surgery, coagulopathy, and anticoagulation treatment. RSH can be difficult to diagnose and can be misdiagnosed as acute appendicitis, as diverticulitis, or as an ovarian mass. Although RSH usually presents as a benign condition, it can be life threatening, especially in the critically-ill patient. Here, we report a case of fatal RSH due to hypovolemic shock in a critically-ill 73-year-old woman, who had received heparin treatment due to acute myocardial infarction in the intensive care unit and who had been successfully treated by conservative management.
