A clonorchiasis case in a captive leopard cat, Prionailurus bengalensis euptilurus, was confirmed by ultrasonographic findings and egg morphologies found in the bile juice sample in the Korea. The leopard cat was introduced from the wild habitat of Gyeongsangnam-do, to Cheongju Zoo in Cheongju-si, Chungcheongbuk-do, Korea in August 2014. Physical examinations were basically performed for quarantine and check-up health. The cat was comparatively good in health except anorexia. The cyst-like bile duct dilation and the increased echogenicity of gall bladder wall and hepatic parenchyma were observed by ultrasonography. Ultrasound-guided needle biopsy was conducted for collecting bile juice and the specimens were observed under light microscope. The numerous small trematode eggs were detected in the bile juice sample of the light microscopy. The eggs were $25-33(28{\pm}3){\mu}m$ by $18-22(20{\pm}1){\mu}m$ in size and showed typical characteristics of Clonorchis sinensis egg, i.e., a dominantly developed operculum, shoulder rim and dust-like wrinkles in surface. To treat the liver fluke infection, 20 mg/kg of praziquantel was orally administered only once to the case. Follow-up studies including fecal examinations were conducted during 2 years after treatment. But no more eggs were detected from the case. In the present study, we described the first clonorchiasis case of leopard cat, which was confirmed by ultrasonographic findings and egg morphologies from the bile juice sample in Korea.

본 연구는 부산 경남지역에서 담낭용종의 위험인자 및 초음파영상의 형태학적 분포를 알아보고자 하였다. 실험 대상은 2016년 1월~5월까지 부산 P병원 내원환자의 복부초음파 영상을 대상으로 하였다. 그 중 복부초음파와 혈청학적 검사를 동시에 실시한 399명을 대상으로 위험인자를 분석하였다. 담낭용종 위험인자들의 통계분석은 독립표본 t검정(independent t-test)과 카이제곱 검정(chi-square test)을 시행하였다. 차이검정 결과를 고려하여 독립변수에 대한 상대 위험비(odds ratio, OR) 산출을 위해 다중 로지스틱 회귀분석(multiple logistic regression analysis)을 시행하여 변수들로부터 예측모형을 산정하여 타당성을 검정하였다. 그 결과 담낭용종 위험인자로 남성, HBsAg 양성, 중성지방이 관련이 있음을 알 수 있었다. 담낭용종의 위험인자로 확인된 남성, HBsAg 양성, 중성지방으로 예측모형 및 예측 확률값을 산정하였다. 예측확률의 민감도 61.0%, 특이도 76.8%를 보였으며, ROC 곡선의 AUC 결과는 0.735를 보여 예측모형의 타당성을 확인할 수 있었다. 복부 초음파검사 상 관찰되는 담낭용종의 형태학적 분석 결과는 고 에코, 유경, 균질한 형태가 가장 많은 분포(27.5%)를 나타내었으며, 용종 개수는 2개(38%), 크기는 5~10 mm (53%)로 가장 많았다. 담낭용종과 관련된 간질환으로는 mild fatty liver (23%), diffuse hepatopathy (21%)로 나타났다.

Objectives: The aim of this retrospective cohort study was to investigate whether non-alcoholic fatty liver disease (NAFLD) was associated with incident bone mineral density (BMD) decrease. Methods: This study included 4536 subjects with normal BMD at baseline. NAFLD was defined as the presence of fatty liver on abdominal ultrasonography without significant alcohol consumption or other causes. Decreased BMD was defined as a diagnosis of osteopenia, osteoporosis, or BMD below the expected range for the patient's age based on dual-energy X-ray absorptiometry. Cox proportional hazards models were used to estimate the hazard ratio of incident BMD decrease in subjects with or without NAFLD. Subgroup analyses were conducted according to the relevant factors. Results: Across 13 354 person-years of total follow-up, decreased BMD was observed in 606 subjects, corresponding to an incidence of 45.4 cases per 1000 person-years (median follow-up duration, 2.1 years). In the model adjusted for age and sex, the hazard ratio was 0.65 (95% confidence interval, 0.51 to 0.82), and statistical significance disappeared after adjustment for body mass index (BMI) and cardiometabolic factors. In the subgroup analyses, NAFLD was associated with a lower risk of incident BMD decrease in females even after adjustment for confounders. The direction of the effect of NAFLD on the risk of BMD decrease changed depending on BMI category and body fat percentage, although the impact was statistically insignificant. Conclusions: NAFLD had a significant protective effect on BMD in females. However, the effects may vary depending on BMI category or body fat percentage.

본 연구는 만성 B형 바이러스성 감염 환자의 간 기능 혈액 검사 수치와 간 섬유화 스캔 검사(FibroScan(R))의 비교 분석을 통한 간 섬유화 스캔 검사의 임상적, 기기적 융합 유용성을 평가하고자 하였다. 2015년 7월 1일부터 2016년 2월 28일까지 대전시 B내과에 내원한 만성 B형 바이러스성 감염 환자 75명의 간 섬유화 스캔 검사 결과와 간 기능 혈액검사 수치를 분석 하고 ROC곡선을 작성하였다. 알라닌 아미노전이요소, 아스파르테이트 아미노전이요소 수치가 각각 0.572, 0.502로 섬유화 수치와 가장 높은 상관관계를 보였다(p<0.000). 감마지티피, 총 빌리루빈, 알칼리성 인산분해효소 수치도 비교적 유의한 상관관계를 보였으나 알파태아단백과 총 단백정량은 통계적으로 유의하지 않았다. 또한 알부민(-0.449)과 혈소판치(-0.373)도 섬유화 수치와 상관관계가 없었다(p<0.000). 간 섬유화 정도가 높은 등급일수록 ROC 곡선의 정확도가 증가하였으며 F4의 간 경변 단계에서 가장 큰 AUROC값을 나타냈다. 따라서 간 섬유화 스캔 검사는 만성 간질환 환자의 간 기능 수치인 알라닌 아미노전이요소, 아스파르테이트 아미노전이요소 수치와 유의한 상관관계를 보여 간의 염증 검사 및 만성 간질환 진단에 매우 유용한 것으로 판단된다.

Objectives : This study was conducted to investigate the associations of non alcoholic fatty liver with metabolic syndrome and the serum carotenoids. Methods : This study was conducted in a general hospital in South Korea from November, 2004 to August, 2005. The study subjects were 350 sampled persons who were aged from 40 years and older (males : 180, females : 170). They were grouped into the normal, mild and severe groups according to fat accumulation in their livers, as determined by ultrasonography. We analyzed the association between non alcoholic fatty liver and metabolic syndrome by multiple logistic regression analysis and we analyzed the association between non alcoholic fatty liver and the serum carotenoids by a general linear model(ANCOVA). Results : After adjustment for the effect of potential covariates, the prevalence of metabolic syndrome was associated with fat accumulation in the liver (p trend <0.001). If the odds ratio of normal group is 1.00, then that of the mild group is 2.80 (95% C.I=1.17-6.71) and that of the severe group is 7.29 (95% C.I=2.76-19.30). The prevalence of metabolic alterations fitting the criteria of metabolic syndrome, according to the class of fat accumulation in the liver, was significantly increased, except for criteria of high blood pressure, a large waist circumference and low HDL (high density lipoprotein) cholesterol level (p trend <0.001). The level of serum ${\beta}$-carotene was decreased according to the class of fat accumulation in the liver (p trend=0.036), but the levels of serum ${\alpha}$-carotene, lycopene, ${\beta}$-cryptoxanthin and lutein were not decreased. Conclusions : This study shows that non alcoholic fatty liver was associated with metabolic syndrome and with the serum ${\beta}$-carotene level.

본 연구는 2020년 5월부터 2020년 12월까지 복부초음파 검사를 위해 내원한 101명의 환자를 대상으로 하였다. 횡파탄성측정검사법을 이용하여 초음파 검사 시 초음파 영상(에코 패턴, 비장비대, 간염) 소견에 따른 탄성도를 알아 알아보고자 하였다. 에코 패턴의 정상 그룹의 횡파탄성측정값은 5.75±1.58 kPa였으며, 에코 패턴의 비정상 그룹은 8.84±4.94 kPa로 에코 패턴 비정상 그룹에서 횡파탄성측정값이 높게 나타났다(p<0.05). 정상 비장 크기에서 간 탄성도 값은 6.33±2.54 kPa였으며, 비장비대의 간 탄성도 값은 13.73±5.48 kPa로 나타났다. 비장비대일 경우 간 탄성도 값이 높게 나타났으며, 통계적으로 유의미한 차이가 있었다(p<0.05). 비장 크기가 증가할수록 간 탄성도 값이 1.485배, 간염이 진행될수록 간 탄성도 값이 1.573배 증가하는 것으로 나타났다(p<0.05). 초음파 영상 소견과 횡파탄성측정법 간 일치도 분석 결과 Kappa 값이 0.922(p<0.05)로 높게 나타났으며, 두 검사 방법 간에 높은 일치도를 보였다. 간 초음파 소견과 함께 횡파탄성측정법 검사의 간 탄성도 값을 추가적으로 비교한다면 간 섬유화 진단에 있어 많은 도움이 될 것으로 생각된다.

A 2-year-old lineolated parakeet (Bolborhynchus lineola) was presented with abdominal distention and respiratory distress for two months. The bird was poorly fleshed and the liver was enlarged on coelomic palpation. Plain and contrast radiographic examinations exhibited hepatomegaly and distended intestinal loop, which compromised the air sacs. Multifocal hyperechogenecity was observed in the liver on ultrasonography. Postmortem gross examination revealed hepatomegaly with numerous pinpoint tan foci in the hepatic parenchyma and distended small intestine filled with adult ascarids. Microscopically, granulomatous hepatitis and enteritis infected by intrahistiocytic acid-fast bacilli were evident. Polymerase chain reaction indicated that the acid-fast bacilli were Mycobacterium avium subsp. avium.

A 10-year-old-girl was referred to our hospital due to abdominal pain. She underwent Roux-en-Y cystojejunostomy for a choledochal cyst at another hospital at the age of 3 months. Abdominal ultrasonography (USG) and computed tomography (CT) showed type I choledochal cyst and multiple gallbladder stones. Because of severe inflammation and adhesion, partial resection of the choledochal cyst and Roux-en-Y hepaticojejunostomy was performed. Two and one half years later, intermittent abdominal pain, fever, nausea and vomiting occured. Abdominal CT scan showed a polypoid nodular lesion in the remnant of the choledochal cyst and probable metastasis at segment 7 of the liver. The duodenum was obstructed by the mass. Liver biopsy revealed moderately differentiated adenocarcinoma. A palliative gastrojejunostomy was performed to relieve duodenal obstruction. She died of hepatic insufficiency 4 months later.
