PURPOSE: Severe cutaneous adverse reactions (SCARs), including Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), and drug reaction with eosinophilia and systemic symptoms (DRESS) to antiepileptic drug (AED), are rare, but result in significant morbidity and mortality. We investigated the major culprit drugs, clinical characteristics, and clinical course and outcomes of AED-induced SCARs using a nationwide registry in Korea. METHODS: A total of 161 patients with AED-induced SCARs from 28 referral hospitals were analyzed. The causative AEDs, clinical characteristics, organ involvements, details of treatment, and outcomes were evaluated. We compared the clinical and laboratory parameters between SJS/TEN and DRESS according to the leading causative drugs. We further determined risk factors for prolonged hospitalization in AED-induced SCARs. RESULTS: Carbamazepine and lamotrigine were the most common culprit drugs causing SCARs. Valproic acid and levetiracetam also emerged as the major causative agents. The disease duration and hospital stay in carbamazepine-induced SJS/TEN were shorter than those in other AEDs (P< 0.05, respectively). In younger patients, lamotrigine caused higher incidences of DRESS than other drugs (P= 0.045). Carbamazepine, the most common culprit drug for SCARs, was associated with a favorable outcome related with prolonged hospitalization in SJS (odds ratio, 0.12; 95% confidence interval, 0.02-0.63, P= 0.12), and thrombocytopenia was found to be a risk factor for prolonged hospitalization in DRESS. CONCLUSION: This was the first large-scale epidemiological study of AED-induced SCARs in Korea. Valproic acid and levetiracetam were the significant emerging AEDs causing SCARs in addition to the well-known offending AEDs such as carbamazepine and lamotrigine. Carbamazepine was associated with reduced hospitalization, but thrombocytopenia was a risk factor for prolonged hospitalization. Our results suggest that the clinical characteristics and clinical courses of AED-induced SCARs might vary according to the individual AEDs.

The Committee of Clinical Practice Guidelines of the Korean Diabetes Association revised and updated the 6th Clinical Practice Guidelines in 2019. Targets of glycemic, blood pressure, and lipid control in type 2 diabetes mellitus (T2DM) were updated. The obese and overweight population is increasing steadily in Korea, and half of the Koreans with diabetes are obese. Evidence-based recommendations for weight-loss therapy for obesity management as treatment for hyperglycemia in T2DM were provided. In addition, evidence from large clinical studies assessing cardiovascular outcomes following the use of sodium-glucose cotransporter-2 inhibitors and glucagon-like peptide 1 receptor agonists in patients with T2DM were incorporated into the recommendations.

We herein describe a 70-year-old woman who presented with respiratory failure due to extensive lung adenocarcinoma. Despite advanced disease, care in the intensive care unit with ventilator support was performed because she was a newly diagnosed patient and was considered to have the potential to recover after cancer treatment. Because prompt control of the cancer was needed to treat the respiratory failure, empirical treatment with an oral epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor was initiated before confirmation of EGFR-mutant adenocarcinoma, and the patient was successfully treated. Later, EGFR-mutant adenocarcinoma was confirmed.

BACKGROUND: Thrombolysis becomes an emerging therapeutic option for acute ischemic stroke. However, few reports exist on its use in the very elderly. We investigated whether there is a difference in the effectiveness and safety of intravenous (IV) and/or intra-arterial (IA) thrombolysis between patients aged > or =80 years and those aged <80 years. METHODS: A consecutive series of patients hospitalized within 12 hours from stroke onset were selected. We evaluated the effectiveness of thrombolysis with modified Rankin scale (mRS) at 3 months, and the safety with symptomatic hemorrhagic transformation (sHT). The odds ratio (OR) of thrombolysis on the favorable mRS (0-2) was calculated using multivariable logistic regression analysis with adjustments for potential confounders. Whether the effectiveness of thrombolysis is age-dependent or not was analyzed by introducing an interaction term (thrombolysisxage group) into multivariable models. RESULTS: Among 219 patients > or =80 years, 21% of patients received IV or IA or combined thrombolysis while 23% of 980 patients <80 years received thrombolysis (P=0.51). With respect to the favorable mRS, the adjusted ORs of thrombolysis were 1.70 (95% confidence interval, 1.08-2.68) in all subjects, 1.61 (0.58-4.49) in those > or =80 years, and 1.71 (1.05-2.78) in those <80 years. There was no significant interaction between age group and thrombolysis (P=0.91). With respect to sHT, the adjusted OR was 4.72 (1.94-11.45) in all subjects with no significant interaction (P=0.86). CONCLUSION: This study suggests that thrombolysis may be equally safe and effective in stroke patients aged > or =80 years versus <80 years.

In the present study, a phylogenetic analysis was undertaken based on the internal transcribed spacer (ITS) rDNA and partial beta-tubulin gene sequence of the Ganoderma species. The size of the ITS rDNA regions from different Ganoderma species varied from 625 to 673 bp, and those of the partial beta-tubulin gene sequence were 419 bp. Based on the results, a phylogenetic tree was prepared which revealed that Korean Ganoderma lucidum strains belong in a single group along with a G. lucidum strain from Bangladesh.

A 50-year-old male, renal transplant recipient, was admitted with fever and chest discomfort. At admission, chest radiologic finding was negative and echocardiography showed minimal pericardial effusion. After 2 days of admission, chest pain worsened and blood pressure fell to 60/40 mmHg. Emergency echocardiography showed a large amount of pericardial effusion compressing the entire heart. Pericardiocentesis was performed immediately. Mycobacterium tuberculosis was isolated from pericardial fluid. Tuberculosis pericarditis should be considered as the cause of cardiac tamponade in renal transplant recipients, even with the absence of pericardial effusion in the initial study or suggestive history.

PURPOSE: Laparoscopic liver resection has gained much popularity in recent years, but relatively few centers have performed hepatectomies in hepatocellular carcinoma (HCC) patients due to the technical difficulties faced with underlying liver cirrhosis. We now present our early experience with laparoscopic liver resection in HCC performed in a single institution. METHODS: From October 2003 until March 2009, 39 laparoscopic liver resections were performed on HCC patients among whom 26 had underlying liver cirrhosis. RESULTS: The location of the tumor was in the left lateral section in 15, segment 5 or 6 in 20, segment 4 in 3 and caudate lobe in 1. Resection involving less than a monosegment was done in 26 and more than 2 segments in 13. Tumor size ranged from 0.8 cm to 6.6 cm (median 2.35) and the resection margin from 0.1 to 6 cm (median 1.5 cm). All patients were either stage I (29) or II (10). There was no difference between cirrhotic and non-cirrhotic patients in operation time (median 210 minutes, range 60~637), change of hematocrit value (4.8%, -1~19.6%), or hospital stay (8 days, 3~67 days). The median follow up duration was 15.1 months, and the 2-year recurrence free survival rate was 48.3%. CONCLUSION: Laparoscopic liver resection in HCC with or without underlying cirrhosis seems to be feasible with minimal morbidity, especially in well selected cases with early stage HCC.

Pyothorax-associated lymphoma is a distinct type of malignant lymphoma composed of lymphocytes, mostly of a B-cell nature. It occurs in patients with a long history of pyothorax and is strongly associated with Epstein-Barr virus infection. We experienced a case of pyothorax-associated lymphoma in a 66-year-old male. The patient had chronic pyothorax after tuberculous pleurisy was treated about 37 years earlier and was hospitalized for a recently occurring chest wall mass. A core needle biopsy of the chest wall mass led to a diagnosis of diffuse large B-cell lymphoma. Pyothorax-associated lymphoma is rare in Korea, but should be considered in patients with chronic pyothorax and a recently occurring pleural mass.
