This study evaluated the correlation between serum uric acid level and the nutrients adequacy ratio (NAR) using data from the Korea National Health and Nutrition Examination Survey (KNHANES) 2016∼2019. This is a cross-sectional study in which 6,579 Korean male adults were divided into quartiles according to their uric acid levels. All analyses were performed with adjusted age. Uric acid decreased as the age increased from the age group 19∼29 years to 30∼49 years and then to 50∼64 years. Interquartile results of serum uric acid levels showed that increases in the serum uric acid levels were associated with decreases in LDL-cholesterol (P＜0.01), triglycerides (P＜0.001), body weight (P＜0.001), waist circumference (P＜0.001), body mass index (P＜0.001), systolic blood pressure (SBP) (P＜0.001), diastolic blood pressure (DBP) (P＜0.001). However, uric acid levels decreased with an increase in HDL cholesterol (P＜0.001). The analysis of the NARs according to the quartiles of serum uric acid levels in men showed that an increase in serum uric acid levels was associated with a decrease in the NAR levels of dietary fiber (P＜0.001), calcium (P＜0.001), and folic acid (P＜0.001).

BACKGROUND: The aim of this study was to analyze the clinical manifestations and efficacy of treatment regimens in order to determine the adequate combination of anti-tuberculotic agent and duration of treatment for tuberculous lymphadenitis. METHODS: We made a review of 373 patients with tuberculous lymphadenitis, who were admitted to four medical college hospitals in Taegu Korea from 1989 to 1998, and their diagnoses were confirmed histologically and bacteriologically. RESULTS: The incidence of tuberculous lymphadenitis was 71.3% in women and 57.7% were between the ages of 20 and 39 years. The most common symptom was painless swelling. The most commonly involved lymph nodes were unilateral superficial cervical lymph node groups. Tuberculous lymphadenitis was accompanied with active pulmonary tuberculosis, commonly. The sensitivity of fine needle aspiration(FNA) in tuberculous lymphadenitis was 79.6% and 92.2% of the patients had a strong positive reaction to the tuberculin skin test. The most commonly prescribed anti-tuberculotic regimen was the combination of INF, RMP, EMB and PZA(62.6%). Eighty percent of patient were treated for 9-12 months. There was no significantly difference in the recurrence rate of tuberculous lymphadenitis between the combinations of anti-tuberculotic agent, including INF and RMP, and between the durations of treatment, for a period of 6 months of treatment, for a period of 6 months of more. CONCLUSION: The combination of FNA cytologic examination and tuberculin skin test may be helpful in the diagnosis of tuberculous lymphadenitis. We propose that the combination of anti-tuberculotic agents, INH, RMP, EMB, and PZA, be prescribed to patients for 6 to 9 months.

Acute cholangitis usually develops in congenital hepatic fibrosis (CHF), accompanied by cystic dilated bile ducts. However, it can also develop in simple CHF and may lead to critical course. A 30-year old man presented with recurrent acute cholangitis without bile duct dilatation. He visited the hospital for febrile sense and abdominal pain in the right upper quadrant. He had been admitted several times for hepatosplenomegaly and cholangitis since childhood and received a liver biopsy 15 years ago. Abdominal computed tomography (CT) and endoscopic retrograde cholangiopancreatography (ERCP) revealed hepatosplenomegaly and a mildly dilated bile duct without stones or biliary cysts. His condition improved after conservative treatment. However, during a two-month follow up period, the patient experienced three episodes of acute cholangitis. A liver biopsy was performed and showed periportal fibrosis and intrahepatic ductular dysplasia, characteristics of congenital hepatic fibrosis. The periportal fibrosis and the infiltration of inflammatory cells were aggravated compared to 15 years ago. There was no evidence of hepatic cirrhosis. He was diagnosed with congenital hepatic fibrosis with recurrent acute cholangitis without intrahepatic duct dilatation, and conservatively treated with antibiotics.

OBJECTIVES: Bedding in childcare centers (CCCs) can hold house dust mite (HDM) allergens. This study examined whether HDM allergen levels can be reduced through the distribution of an educational newsletter on bedding control to parents of CCC children in Korea. METHODS: All 38 CCCs were measured for Der 1 (sum of Der f 1 and Der p 1) concentrations on classroom floors and bedding before the intervention. Educational newsletters on children’s bedding control were sent to 21 CCCs by mail, and teachers were asked to distribute the newsletters to the parents of the children (intervention group). The remaining 17 CCCs were not sent newsletters (control group). The measurement of Der 1 concentrations in 38 CCCs was repeated after the intervention. Dust samples were collected with a vacuum cleaner and analyzed using enzyme-linked immunosorbent assay methods. RESULTS: The Der 1 concentrations on the bedding were significantly higher than those on the floors in 38 CCCs at baseline (p<0.05). Although changes of the Der 1 concentrations for the control group (n=17) were not significant, Der 1 concentrations for the intervention group (n=21) decreased significantly from 2077.9 ng/g dust to 963.5 ng/g dust on the floors and from 3683.9 ng/g dust to 610.4 ng/g dust on bedding (p<0.05). CONCLUSIONS: The distribution of educational newsletters on bedding control to parents may be an effective means of controlling HDMs in CCCs.

OBJECTIVES: A number of studies on the trends of socioeconomic differences in suicide mortality have indicated that these inequality gaps have widened over time and highlight that certain occupations have more suicide risk than others. However suicide rates according to occupation based socioeconomic position have not been frequently studied in Korea. The purpose of this study is to report trends and inequality of suicide according to occupation based social class during 1993-2007 in Korea and to identify occupations with significantly high standardized mortality ratios (SMRs) and proportional mortality ratios (PMRs) for both men and women. METHODS: Korean census records for the years 1995, 2000, and 2005 were linked with the cause of death records from Korean National Statistical Office (KNSO) for the periods 1993-1997, 1998-2003, and 2004-2007 respectively. This data was used to calculate age adjusted proportional mortality ratios (PMRs) and standardized mortality ratios (SMRs) for both men and women aged 25~54 years according to five occupation based socioeconomic positions. RESULTS: Among men, the agricultural-fishery-forestry group had the greatest suicide rate (SMR: 341) with a high PMR (113) and the manual labor group showed the highest PMR (118), while the managers-professional occupation group showed the lowest sPMR (78) and SMR (21). Among women, the agricultural-fishery group had the highest score in SMR (316) and PMR (130), and the technical-artificer group showed the lowest sPMR (71) and SMR (27). The inequality gaps in the suicide mortality rate according to occupation had widened during 1998-2002, but showed a recovery trend plot after 2003. CONCLUSIONS: Although the occupation based socioeconomic inequalities show a recovery trend after 2003, the excess inequality from suicide remains as high as it was prior to the 2002 year in some occupational groups. The results of the current study indicate that the manual and agricultural-fishery-forestry groups were high risk groups of suicide.

Nimesulide, highly selective cyclooxygenase inhibitor-2, is a newly developed, non-steroidal anti-inflammatory drug (NSAID) with low toxicity in gastrointestinal tract. But recently, seven cases of nimesulide-induced hepatitis of which types were hepatocellular, hepatocanalicular, and mixed damage were reported. Our case of nimesulide-induced hepatic damage was mixed cholestatic and hepatotoxic hypersensititvity reaction, and her story was as follows. A 70-year female patient's first hepatic event happened in Jaunuary, 1998 after taking nimesulide 200mg daily for 50 days from November 1997, but it was cleared. She was admitted to our unit because of jaundice, edema and ascites in May, 1998 after retrial of nimesulide 150 mg daily for 50 days. Biochemical determinations showed increase of AST (181 IU/L), ALT (110 IU/L), bilirubin (20.3 mg/dL) and albumin (2.3 g/dL). Prothrombin time was also prolonged upto 2.51 INR. But neither viral markers such as anti-HCV, HBsAg, anti-HBc IgM, anti-HAV IgM, anti-CMV, anti-EBV IgG and IgM nor other immunologic markers such as ANA, SMA, and AMA were positive. Ultrasonography showed diffuse hyperechogenicity in liver and mild splenomegaly but no dilatation in biliary tract. Liver biopsy showed portal to portal bridging necrosis with severe hepatocytic cholestasis. Her liver function returned to normal after discontinuation of nimesulide. At 8 months after beginning treatment, she complained of recurrent epistaxis and abdominal distension. At this time, her liver biopsy showed cirrhosis. In conclusion, we considered that this case was nimesulide-induced Liver cirrhosis.

BACKGROUND: To evaluate the frequency and clinical significance of lymph node micrometastasis in patients of non-small-cell lung cancer pathologically staged to be T1-2,N0. METHOD: From consecutive 29 patients of non-small-cell lung cancer who received curative operation and routine systemic nodal dissection, we immunohistochemically examined 806 lymph nodes from mediastinal, hilar and peribronchial lesion. All slides were stained with hematoxylin and eosin staining for one section and with cytokeratin AE1/AE3 antibody for another consecutive section of same lymph node to find out micrometastasis. RESULTS: In 806 lymph nodes examined, no tumor cell was seen on hematoxylin and eosin staining and micrometastic foci were shown to be on 0.37%(3) of 806 lymph nodes, in which were upper paratracheal, interlobar and peribronchial lymph node. These three positive stains constitute 10.3%(3) of the 29 patients with non-small-cell lung cancer. Nine patients died from disease progression(4), postoperative complication(3) and concomitant diseases(2). The four patients with disease progression did not show evidence of micrometastasis on their lymph node examination. CONCLUSION: The frequency of lymph node micrometastasis was in 0.37% of 806 lymph nodes examined. The study results might suggested that routine analysis of micrometastasis on the lymph node didn't give any clinical implication on patients with non-small-cell lung cancer.

Gangliocytic paraganglioma is a rare tumor that is usually seen in the duodenum. This neoplasm generally behaves in a benign fashion, although instances of recurrence and lymph node metastasis have been described. We experienced a case of incidentally found gangliocytic paraganglioma treated with endoscopic resection. A 61-year-old man was referred because of submucosal tumor adjacent to the major papilla. Endoscopic biopsy revealed paraganglioma. Abdominal CT showed that there was no evidence of a duodenal mass or lymphadenopathy. This tumor was resected endoscopically by electrosurgical snare polypectomy. The excised tumor measured 1.0 cm in diameter. Histopathological examination revealed a benign gangliocytic paraganglioma and the resection margins were free of tumor. At the 6-month follow-up, the patient was still asymptomatic and no residual tumor was detected at the resection site.

Limb-Girdle Muscular Dystrophy 2B (LGMD2B) presents with proximal and/or distal muscle weakness and markedly high creatine kinase level. It is caused by the loss of dysferlin due to mutations in the DYSF gene. Due to its similar clinical features as inflammatory myopathy, it is often difficult to distinguish between the two. We present a case of a 48-year-old male who developed progressive proximal muscle weakness, papulosquamous lesions on the knuckles, elevated levels of muscle enzymes, and electromyogram abnormalities. Based on the clinical presentation, the initial impression was dermatomyositis, yet it was refractory to immunosuppressive therapy. Subsequently, dysferlin immunostaining and genetic analysis led to the final diagnosis of LGMD2B. This case shows that LGMD2B can present with extramuscular symptoms mimicking inflammatory myopathy in later stages of life. Dysferlin immunostaining and/or genetic analysis of the DYSF gene are essential for its diagnosis.
