BACKGROUNDS/AIMS: The occurrence of acute hepatitis A is increasing and its progression to fulminant hepatic failure (FHF) is frequent. We investigated the frequency and clinical outcomes of fulminant hepatitis A and also analyzed the predictive factors of spontaneous survival. METHODS: A total of 568 patients presented with acute hepatitis A from January 2003 to June 2008, of which the 35 (6.2%) patients with FHF were divided into two groups: spontaneous survival and transplant/death. These two groups were compared according to various clinical features including the MELD score and King's College Hospital (KCH) criteria. RESULTS: The rate of FHF development increased over time among patients with acute hepatitis A: 0% in 2003, 3.4% in 2004, 3.2% in 2005, 6.0% in 2006, 7.7% in 2007, and 13.0% in 2008. Twenty patients (57.1%) showed spontaneous survival, 13 (37.1%) received liver transplantation, and 5 (14.3%) died during hospitalization. The two groups of spontaneous survival (N=20) and transplant/death (N=15) showed significant differences in prothrombin time at admission and at its worst value, albumin at its worst value, and hepatic encephalopathy grade at admission and at its worst value. The MELD score was lower in the spontaneous-survival group than in the transplant/death group (27.0+/-7.8 vs. 37.0+/-7.1, mean+/-SD; P=0.001). However, KCH criteria did not differ significantly between the two groups. On multivariate analysis, HEP grade was the only significant predictive factor, being negatively correlated with spontaneous survival (OR=0.068, P=0.025). CONCLUSIONS: FHF due to hepatitis A has increased in recent years, and in our cohort the HEP grade was closely associated with spontaneous survival.

In 2005, Kreidstein first proposed the term "Cutis pleonasmus," a Greek term meaning "redundancy," which refers to the excessive skin that remains after massive weight loss. Cutis pleonasmus is clearly distinguishable from other diseases showing increased laxity of the skin, such as pseudoxanthoma elasticum, congenital and acquired generalized cutis laxa. Although individuals who are severely overweight are few and bariatric surgeries are less common in Korea than in the West, the number of these patients is increasing due to changes to Western life styles. We report a case for a 24-year-old man who presented with generalized lax and loose skin after massive weight loss. He was diagnosed with cutis pleonasmus based on the history of great weight loss, characteristic clinical features and normal histological findings. To the best of our knowledge, this is the first report of cutis pleonasmus in Korea.

Hafnia alvei is a gram-negative bacillus that is rarely isolated from human clinical specimens and is rarely pathogenic. This organism is an extremely uncommon cause of spontaneous bacterial peritonitis (SBP). We report a case of an 83-year-old male with hepatitis C-associated liver cirrhosis and hepatocellular carcinoma who was diagnosed with SBP caused by H. alvei. He was admitted to an university-affiliated hospital with fever and abdominal pain. There were 2 episodes of SBP during 2 months. Although isolates of H. alvei from ascitic fluid were shown to be susceptible to cefotaxime, responses for cefotaxime treatment were inadequate in both episodes. Therefore, cefotaxime was switched to imipenem in the first episode and to ciprofloxacin in the second, according to the results of antimicrobial susceptibility. After the antibiotics was changed, SBP was resolved.

BACKGROUND AND PURPOSE: Chronic kidney disease (CKD) is an established risk factor for numerous cardiovascular diseases including stroke. The relationship between the baseline estimated glomerular filtration rate (eGFR) and clinical 3-month outcomes in patients with acute ischemic stroke were evaluated in this study. METHODS: This was a prospective cohort study involving a hospital-based stroke registry; 1373 patients with acute ischemic stroke were enrolled. Patients were divided into the following four groups according their eGFR (calculated using the CKD Epidemiology Collaboration equations): > or =60, 45-59, 30-44, and <30 mL/min/1.73 m2. The primary endpoint of poor functional outcome was defined as 3-month death or dependency (modified Rankin Scale score > or =3); secondary endpoints were neurological deterioration (increase in National Institutes of Health Stroke Severity score of > or =4 at discharge compared to baseline) during hospitalization and in-hospital mortality. RESULTS: The overall eGFR was 84.5+/-20.8 mL/min/1.73 m2 (mean+/-SD). The distribution of baseline renal impairment was as follows: 1,218, 82, 40, and 33 patients had eGFRs of > or =60, 45-59, 30-44, and <30 mL/min/1.73 m2, respectively. At 3 months after the stroke, 476 (34.7%) patients exhibited poor functional outcome. Furthermore, a poor functional outcome occurred more frequently with increasingly advanced stages of CKD (rates of 31.9%, 53.7%, 55.0%, and 63.6% for CKD stages 1/2, 3a, 3b, and 4/5, respectively; p<0.001). Multivariate analysis revealed that a baseline eGFR of <30 mL/min/1.73m2 increased the risk of a poor functional outcome by 2.37-fold (p=0.047). In addition, baseline renal dysfunction was closely associated with neurological deterioration during hospitalization and with in-hospital mortality. CONCLUSIONS: A low baseline eGFR was strongly predictive of both poor functional outcome at 3 months after ischemic stroke and neurological deterioration/mortality during hospitalization.

The Pogo mouse is an autosomal recessive ataxic mutant that arose spontaneously in the inbred KJR/MsKist strain derived originally from Korean wild mice. The ataxic phenotype is characterized by difficulty in maintaining posture and side to side stability, faulty coordination between limbs and trunk, and the consequent inability to walk straight. In the present study, the cerebellar concentrations of glutamate and GABA were analyzed, since glutamate is a most prevalent excitatory neurotransmitter whereas gammar-aminobutyric acid (GABA) is one of the most abundant inhibitory neurotransmitters, which may be the main neurotransmitters related with the ataxia and epilepsy. The concentration of glutamate of cerebellum decreased significantly in ataxic mutant Pogo mouse compared to those of control mouse. However, GABA concentration was not decrease. These results suggested that the decrease in glutamate concentration may contribute to ataxia in mutant Pogo mouse.

BACKGROUND: Controversies exist whether arteriovenous fistula (AVF) placement is preferred over arteriovenous graft (AVG) for elderly patients. Current guidelines did not offer specific recommendations. Thus, this study was conducted to analyze the all-cause mortality and primary patency associated with various vascular access (VA) types according to age group. METHODS: This retrospective observational study investigated the Korean insurance claims data of chronic kidney disease patients who began hemodialysis between January 2008 and December 2016. We investigated all-cause mortality associated with initial VA in incident hemodialysis patients and primary patency between AVF and AVG according to age group. RESULTS: The proportion of patients with a tunneled dialysis catheter (TDC) that was first placed for VA increased from 18.4% in 2008 to 52.3% in 2016. Incident hemodialysis patients with a TDC or AVG for the initial VA had significantly higher mortality risk than patients with an AVF, except for patients over 85 years, who showed no significant difference in all-cause mortality regardless of VA type. In the patency analysis on initial AV access, AVG had significantly poorer primary patency than AVF in all age groups. CONCLUSION: AVF had better patency than AVG in all age groups; however, the benefit of AVF attenuated in the older age groups. The mortality rate between AVF and AVG was not significantly different in patients over 85 years. Therefore, a “patient-first” approach should be emphasized over a “fistula-first” approach in AV access creation for incident hemodialysis patients older than 85 years.

PURPOSE: Adiponectin (ADPN) has been known to protect against cardiovascular disease (CVD) in metabolic syndrome with normal renal function for its anti-inflammatory and anti-atherogenic property. However, it is still unclear whether ADPN is associated with cardiovascular outcomes in end-stage renal disease (ESRD) patients. METHODS: This study included 80 non-diabetic ESRD patients [mean age, 52.8+/-13.7 years; dialysis duration, 67.1+/-52.0 months; hemodialysis (HD), 35 pts; peritoneal dialysis (PD), 45 pts] who survived for more than 3 months after the start of dialysis, and serum ADPN levels were measured at the beginning of the study. We conducted a longitudinal follow-up to evaluate the association of serum ADPN level with cardiovascular outcomes for 29.3+/-6.7 months. RESULTS: ADPN was inversely correlated with fasting serum insulin (r=-0.309, p=0.006) and HOMA-IR (r=-0.321, p=0.004) in ESRD patients. In a multiple linear regression analysis adjusted for age, gender, waist to hip ratio (WHR), and HDL-cholesterol, HOMA-IR (beta=-0.880, p=0.041) was an independent factor associated with serum ADPN level. Kaplan-Meier analysis revealed that patients with higher ADPN levels (> or =15.8 microgram/mL) had a significantly higher survival rate compared with lowers (<15.8 microgram/mL) (p=0.032). Cox proportional hazard model adjusted for age, WHR, creatinine, CRP, and previous CVD history revealed that serum ADPN level (HR, 0.899; 95% CI, 0.818-0.987; p=0.026) was an independent determinant of cardiovascular outcomes. CONCLUSION: These findings suggest that lower ADPN levels independently predict cardiovascular events in non-diabetic ESRD patients.

TrkA is essential components of the high-affinity NGF receptor necessary to mediate biological effects of the neurotrophins NGF. Here we report on the expression of trkA in the cerebral cortex and diencephalon of mongolian gerbils during postnatal development. The expression of trkA was identified by immunohistochemical method. In parietal cortex and piriform cortex, higher levels of trkA-IR (immunoreactivity) were detected at 3 days postnatal (P3) and at P9. Although trkA was not expressed till P3 in the parietal cortex, it was detectable at birth in the piriform cortex. Several regions, such as Layers I, IV & VI, did not show much expression. Layer I showed especially weak labeling. In the hippocampus, thalamus, and hypothalamus, higher levels of trkA-IR were detected at P6 and P12 than earlier days. But trkA was not expressed at birth in the hippocampus, at P3 in the reticular thalamic nucleus (Rt), or neonatally in the dorsomedial hypothalamic nucleus (DM). This data shows that expression of trkA is developmentally regulated and suggests that high affinity neurotrophin-receptors mediate a transient response to neurotrophines in the cerebral cortex and diencephalon during mongolian gerbil brain ontogeny.

BACKGROUND: Pigmented basal cell carcinomas (PBCC) may be confused with melanoma and other benign pigmented skin lesions. Dermoscopy is a noninvasive technique that is known to increase the diagnostic accuracy of benign versus malignant pigmented skin lesions. Menzies et al recently proposed a simple dermoscopic model for the diagnosis of PBCCs. OBJECTIVE: To demonstrate whether this criteria was adequate for Korean PBCC patients and seek other characteristic dermoscopic findings in Korean PBCCs. METHODS: Dermoscopic images of 50 biopsy-proven PBCCs were examined. RESULTS: Negative features such as a pigment network were not observed in all PBCCs. Positive features-ulceration, large blue-gray ovoid nests, multiple blue-gray globules, maple leaf-like areas, spoke wheel areas and arborizing (treelike) telangiectasia were present in 39 (78.0%), 41 (82.0%), 33 (66.0%), 21 (42.0%), 1 (2.0%) and 32 (64.0%) of 50 PBCCs respectively. All PBCCs satisfied the dermoscopic criteria for diagnosis of PBCC suggested by Menzies et al. Other dermoscopic features were as follows; multiple blue-gray dots (28.0%), milia-like cysts (8.0%), granules (6.0%), diffuse blue-white area (6.0%) and hairpin vessels (2%). Forty-four % of lesions had less than 50% pigmentation of the area and 38.0% of lesions had more than 75% pigmentation. CONCLUSION: The criteria of PBCC proposed by Menzies et al was useful for dermoscopic diagnosis of Korean PBCCs. Ulceration and pigmentary features such as large blue-gray ovoid nests, multiple blue-gray globules, maple leaf-like areas, multiple blue-gray dots, granules and larger pigmented areas were more frequently observed in Korean PBCCs. However, other specific dermoscopic findings for diagnosis of PBCC in Koreans were not present.
