Gilbert's syndrome is caused by a reduction in the activity of uridine diphosphate glucuronosyltransferase (UGT) and induces chronic, non-hemolytic unconjugated hyperbilirubinemia. It has been suggested that 3-10% of the population has Gilbert's syndrome. Commonly, Gilbert's syndrome causes mild symptoms. However, a case of Gilbert's syndrome with severe neonatal hyperbilirubinemia is presented here. The patient developed jaundice three days after birth. Five days after birth, the patient's total serum bilirubin level was 34 mg/dL. The patient received intensive phototherapy and was given oral phenobarbital. Hemolytic hyperbilirubinemia was excluded on the basis of laboratory tests. Heterozygote polymorphisms of the promoter region (-3279T>G) and exon 1 (211G>A) were found in UGT1A1 gene. After discharge, the patient did not require any further treatment. This is the first case of proven Gilbert's syndrome with severe neonatal hyperbilirubinemia in Korea.

Hepatitis A virus (HAV) infection is a common cause of acute hepatitis, but is rarely responsible for neonatal hepatitis. HAV infection is usually transmitted by the fecal-oral route, but during the neonatal period can be transmitted by the intrauterine vertical route or postnatal horizontal route. HAV infection is usually self-limited, but it can be potentially life-threatening in adults. The clinical course and symptoms are mild and the infection can be asymptomatic in newborns. Recently, we experienced a case of symptomatic neonatal hepatitis A. To our knowledge, this is the first case of neonatal hepatitis with HAV infection in Korea.

Background: This study aims to contribute to the adjustment of the appropriate doctor manpower by analyzing the distribution, supply and demand, and estimation of the doctor manpower. Methods: This study utilized the medical personnel data of the Ministry of Health and Welfare, population trend data of the National Statistical Office, and health insurance benefit performance data of the National Health Insurance Service. Based on 2021, we compared the number of doctors in actual supply and the number of doctors in demand according to the amount of medical use by gender and age for 250 regions. Logistic regression analysis and scenario analysis were performed to estimate the future medical workforce by considering the demand for doctors according to the future demographic structure, the size of the quota in medical schools, and the retirement rate. Results: There were 186 regions in which the supply of doctors was below average, and the average ratio of the number of doctors in supply to demand in the region was 62.1%. Conclusion In order to increase the number of active doctors nationwide to at least 80%, 7,756 people must be allocated. The number of doctors in demand is estimated to decrease after increasing to 1.492 times in 2059. The future projected number of doctors is expected to increase to 1.349 times in 2050 and then decrease taking into account the doctor quota and the retirement rate.

Multiple endocrine neoplasia type 2B (MEN 2B) is an autosomal dominant disorder characterized by medullary thyroid cancer, pheochromocytoma, neuroma and Marfanoid feature. Medullary thyroid cancer occurs in more than 95% patients of MEN 2B and increases mortality. So, the early diagnosis of multiple endocrine neoplasia is very important, because in the early diagnosed and treated medullary thyroid cancer, the prognosis is excellent. This is a case of multiple endocrine neoplasia type 2B that diagnosed early by conjunctival neuroma. A 15-year-old female patient was presented with both conjunctival masses that occurred 6 months ago. The excisional biopsy revealed conjunctival neuroma. The multiple endocrine tumor was suspected, further evaluation was performed. Medullary thyroid cancer was confirmed by thyroid ultrasound and fine needle aspiration. Finally, MEN type 2B was confirmed by a RET mutation genetic testing.

Food deprivation can affect performance on difficult cognitive task, such as the delayed nonmatch-to-place T-maze task (DNMT). The importance of food deprivation on maintaining high motivation for DNMT task has been emphasized, but not many studies have investigated the optimal conditions for depriving rodents to maximize performance. Establishing appropriate conditions for food deprivation is necessary to maintain DNMT task motivation. We applied different conditions of food deprivation (1-h food restriction vs. 1.5-g food restriction; single caging vs. group caging) and measured body weight and the number of correct choices that 8-week-old C57BL/6J mice made during the DNMT task. The 1.5-g food restriction group maintained 76.0+/-0.6% of their initial body weight, but the final body weight of the 1-h food restriction condition group was reduced to 62.2+/-0.8% of their initial body weight. These results propose that 1.5-g food restriction condition is effective condition for maintaining both body weight and motivation to complete the DNMT task.

Biliary cystadenomas are benign but potentially malignant cystic neoplasm. The preferred treatment is radical resection because it is difficult to differentiate a benign from a malignant biliary cystadenoma. A 40 year-old woman presented with moderate abdominal discomfort. Esophageal varix was found up to mid-esophagus on endoscopy. She has no prior history of liver disease or chronic alcohol ingestion. About 15cm sized biliary cystadenoma was diagnosed by ultrasonography, computed tomography and magnetic resonance imaging. Serum level of bilirubin, alanine aminotransferase, alkaline phosphatase, gamma-glutamyl transpeptidase and tumor marker were elevated. The patient underwent US-guided aspiration. Tumor markers from the aspirated fluid are increased. Left hepatectomy was performed to completely remove the cyst. Histology of the resected specimen confirmed a biliary cystadenoma of the liver with ovary-like stroma. Without prior history of liver disease or chronic alcoholic ingestion, incidental finding of esophageal varix could show an important clue for diagnosis of biliary cystadenoma.

In order to assess inhibitory potentials of white rose petal extracts (WRPE) on the activities of enzymes related to dermal aging according to the extraction conditions, three extraction methods were adopted. WRPE was prepared by extracting dried white rose (Rosa hybrida) petals with 50% ethanol (WRPE-EtOH), Pectinex(R) SMASH XXL enzyme (WRPE-enzyme) or high temperature-high pressure (WRPE-HTHP). In the inhibition of matrix metalloproteinase-1, although the enzyme activity was fully inhibited by all 3 extracts at 100 microg/mL in 60 min, partial inhibition (50-70%) was achieved only by WRPE-EtOH and WRPE-enzyme at 50 microg/mL. High concentrations (> or =250 microg/mL) of all 3 extracts markedly inhibited the elastase activity. However, at low concentrations (15.6-125 microg/mL), only WRPE-EtOH inhibited the enzyme activity. Notably, WRPE-EtOH was superior to WRPE-enzyme and WRPE-HTHP in the inhibition of tyrosinase. WRPE-EtOH significantly inhibited the enzyme activity from 31.2 microM, reaching 80% inhibition at 125 microM. In addition to its strong antioxidative activity, the ethanol extract of white rose petals was confirmed to be effective in inhibiting skin aging-related enzymes. Therefore, it is suggested that WRPE-EtOH could be a good candidate for the improvement of skin aging such as wrinkle formation and pigmentation.

Background: Previous studies suggested the correlation between thyroid and kidney functions, especially the high prevalence of hypothyroidism in chronic kidney disease. This study aimed to evaluate the influence of hypothyroidism on kidney function in Korean adults by using data from a representative nationwide survey. Methods: This was a cross-sectional study composed of 5,250 individuals aged ≥19 years who were enrolled in the sixth Korea National Health and Nutrition Examination Survey. The participants were classified into three groups of patients with euthyroidism, subclinical hypothyroidism, and overt hypothyroidism according to thyroid function. Chronic kidney disease was defined as having a decreased estimated glomerular filtration rate (eGFR) of <60 mL/min/1.73 m2. Univariate and multivariate logistic regression analyses were used to evaluate the prevalence and adjusted odds ratio (aOR) of chronic kidney disease. Results: Compared with the euthyroidism group, the subclinical and overt hypothyroidism groups showed higher prevalence rates of chronic kidney disease in both sexes. This tendency was significant in the elderly people aged ≥65 years. In the multivariate logistic regression analysis, the subclinical hypothyroidism group did not show a significant difference (adjusted odds ratio [aOR], 1.78; 95% confidence interval [CI], 0.82–3.87) from the euthyroidism group. In the overt hypothyroidism group, the aOR of chronic kidney disease was significantly higher (aOR, 5.90; 95% CI, 1.73– 20.15) than that in the euthyroidism group. Conclusion Overt hypothyroidism was associated with decreased eGFR and may be considered as an independent risk factor of chronic kidney disease.
