Drug-induced toxic hepatitis is a relatively common hepatic disease in children, and it is usually self-limiting upon cessation of the offending drugs. Antituberculous drugs are well known for inducing hepatitis. Some cases of drug-induced hepatitis with autoimmune features have been reported; in these cases, the offending drugs were usually methyldopa, nitrofurantoin, minocycline, and interferon. The authors report the first case in Korea of drug-induced autoimmune hepatitis associated with thyroiditis and multiple autoantibodies that was induced by the antituberculous drugs isoniazid and rifampin.

BACKGROUND: The prevalence of obesity is increasing year after year in Korean; and gastroesophageal reflux disease(GERD) is increasing in this population as well. The aim of this study is to assess the association between age, body mass index(BMI) and GERD in healthy Korean adults. METHODS: Analysis was done on 1,016 subjects who had not had malignancy, uncontrolled metabolic disease, enteric surgery and organic esophageal disease. They completed a questionnaire that included past history and reflux symptoms. Endoscopy was performed by two gastroenterologists who were not given any patient information. Existence of GERD was determined by the esophageal syndrome criteria of the Montreal guidelines. Subjects were categorized by BMI, initially as: underweight, normal(18.5< or =BMI<25), overweight(25< or =BMI<30) and obese by the WHO criteria, and then as: underweight, normal(18.5< or =BMI<23), overweight(23< or =BMI<25) and obese by the Asian-Pacific criteria. RESULTS: The overall[is this correct] prevalence of GERD in our subjects was 15.5%. Age and sex were not correlated factors for GERD. By the WHO and the Asian-Pacific criteria, GERD was present in underweight(10.0%, 12.1%), normal(13.9%, 14.4%), overweight(18.6%, 13.0%) and obese groups(21.0%, 18.8%). No meaningful association was seen between BMI and GERD in either of the classified groups. Erosive GERD was seen in 83 subjects (8.2%) on endoscopy. The obese(BMI> or =25) group(12.1%) showed a meaningful increment in the prevalence of erosive GERD compared to the non-obese(BMI<25) group(6.2%)(p value 0.002). CONCLUSION: The prevalence of GERD in healthy Korean adult subjects was not closely associated with obesity and age[according to BMI]; however, erosive GERD was found to have a strong association with obesity.

Anaplasma species are obligate intracellular pathogens that can cause tick-borne diseases in mammalian hosts. To date, very few studies of their occurrence in Korean native goats (Capra aegagrus hircus) have been reported. In the present study, we investigated Anaplasma infection of Korean native goats on Jeju Island, Republic of Korea, and performed phylogenetic analysis based on the 16S rRNA gene sequences. Our results showed that Anaplasma infection was found mostly in adult female goats. The phylogenetic tree revealed that the 7 sequences identified in Korean native goats could belong to Anaplasma sp. and were distinct from A. marginale, A. centrale, and A. ovis. The results indicated that the sequences identified to belong to Anaplasma were closely related to sequences isolated from goats in China and were clustered within the same group. To our knowledge, this is the first study to detect Anaplasma sp. infection in Korean native goats.

The objective of this study was to investigate the prevalence of tick-borne pathogens in the Korean water deer (Hydropotes inermis argyropus). Pathogens were identified using PCR which included Anaplasma, Ehrlichia, Rickettsia, and Theileria. Rickettsia was not detected, whereas Anaplasma, Ehrlichia, and Theileria infections were detected in 4, 2, and 8 animals, respectively. The most prevalent pathogen was Theileria. Of the 8 Theileria-positive animals, 2 were mixed-infected with 3 pathogens (Anaplasma, Ehrlichia, and Theileria) and another 2 animals showed mixed-infection with 2 pathogens (Anaplasma and Theileria). Sequencing analysis was used to verify the PCR results. The pathogens found in this study were identified as Anaplasma phagocytophilum, Ehrlichia canis, and Theileria sp. To the best of our knowledge, this is the first report identifying these 3 pathogens in the Korean water deer. Our results suggest that the Korean water deer may serve as a major reservoir for these tick-borne pathogens, leading to spread of tick-borne diseases to domestic animals, livestock, and humans. Further studies are needed to investigate their roles in this respect.

BACKGROUND: There is an increasing interest in physical activity as a preventive and/or therapeutic option of non alcoholic fatty liver disease (NAFLD). The aim of this study was to examine the association between physical activity and ultrasound-diagnosed NAFLD. METHODS: From April to June 2007, 198 clients who had consumed alcohol less than 140 gram per week among 598 clients who visited a general hospital for medical check-up were enrolled in this study. Clinical, biochemical variables and physical activity were compared. Physical activity was measured by self-reported questionnaire using IPAQ-short form in Korean version. Multiple logistic regression analysis was used to identify independent association. RESULTS: The prevalence of NAFLD was significantly lower in the physical active group (more than 1500 MET- minutes per week) compared to the inactive group (9.6% vs 19.2%, P<0.05). This association was not attenuated when adjusted for age, BMI, HDL cholesterol, triglycerides, fasting glucose, and HOMA2-IR (Odds Ratio 0.23 [95% CI 0.07~0.77, P<0.05]). CONCLUSION: Compared to the physically inactive group, the risk of NAFLD was lower in the physically active group. Our data suggests that regular and moderate physical exercise can prevent the development of fatty liver disease.

Nevus lipomatosus cutaneous superficialis is a very rare disorder characterized by nevoid fatty growth in the dermis. It usually arises in the pelvic girdle, so is unfamiliar to most otolaryngologists. A case of a 72-year-old male with nevus lipomatosus cutaneous superficialis in the nasal cavity is presented with a brief review of the disease.

Neurofibroma of the larynx is a rare disease. Endolaryngeal neurofibromas may take place as an isolated lesion or a part of multiple neurofibromatosis (von Recklinghausen's disease). A case of endolaryngeal neurofibroma was the first reported by Suchanek in 1925. Following the first report, there have been sporadic reports of endolaryngeal neurofibroma When the lesion is in the larynx, the major site is the aryepiglottic fold or the arytenoid, because the branch of the superior laryngeal nerve is involved. Rarely, a vocal cord is also concerned. Surgical excision is the treatment of choice. We report a case of isolated neurofibroma arising from the right true vocal cord.

Acute visual loss may occur in association with sinusitis either as a complication of orbital cellulitis or, less frequently, as a part of the orbital apex syndrome. Originally, an orbital apex syndrome is associated with an affection of the vessels and nerves passing through the superior orbital fissure and the optic foramen. A classical feature of orbital apex syndrome is presented with visual loss and ophthalmoplegia, but with minimal or no signs of orbital inflammation such as proptosis, chemosis, or lid edema. We present a case of male patient with alternating bilateral visual loss with ophthalmoplegia secondary to paranasal sinusitis.

Cytomegalovirus(CMV) infections are common in immune compromised situations such as human immunodeficiency virus infection and organ transplantation. However CMV colitis had been rarely found in immunocompetent individuals. We experienced a case of an 83-year-old female patient, initially immune competent, who developed a massive lower gastrointestinal bleeding caused by CMV colitis. Previously, multiple antibiotics were used for nontuberculous Myco- bacterium and other bacterial infections after total knee arthroplasty. Colonoscopy revealed multiple ulcerations and mucosal congestion with hemorrhage. In spite of ganciclovir therapy, our patient did not recover.

Nematomorpha, horsehair or Gordian worms, include about 300 freshwater species in 22 genera (Gordiida) and 5 marine species in 1 marine genus (Nectonema). They are parasitic in arthropods during their juvenile stage. In the present study, the used gordian worm was found in the feces of a dog (5-month old, male) in July 2014. Following the worm analysis using light and scanning electron microscopes, the morphological classification was re-evaluated with molecular analysis. The worm was determined to be a male worm having a bi-lobed tail and had male gonads in cross sections. It was identified as Gordius sp. (Nematomorpha: Gordiidae) based on the characteristic morphologies of cross sections and areole on the cuticle. DNA analysis on 18S rRNA partial sequence arrangements was also carried out, and the gordiid worm was assumed to be close to the genus Gordius based on a phylogenic tree analysis.
