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.

Background:
Patients with diabetes are known to be at high risk for end-stage kidney disease (ESKD), but the accurate annual risk data for new-onset ESKD is still limited. In South Korea, the prevalence and incidence of ESKD are increasing more rapidly compared to the global average. This study aimed to determine the incidence rate (IR) of ESKD by diabetes status from 2012 to 2022.
Methods:
Using data from the Korean National Health Insurance Service, we calculated the IR and hazard ratio (HR) for newonset ESKD in the general population. Individuals were categorized based on diabetes status into nondiabetes, impaired fasting glucose (IFG), diabetes duration <5 and ≥5 years.
Results:
Among the participants, 67.6% were nondiabetic, 22.3% had IFG, and 10% had diabetes. In Korea, the IRs of ESKD were 139 per million population (pmp) for nondiabetes, 188 pmp for IFG, 632 pmp for diabetes <5 years, and 3,403 pmp for diabetes ≥5 years. An advanced estimated glomerular filtration rate (eGFR) category was the strongest risk factor for ESKD development. However, even in patients with normal renal function, those with long-standing diabetes had a 14-fold higher risk of ESKD compared to nondiabetic individuals. The risk of ESKD associated with diabetes increased exponentially with declining renal function. Notably, IFG showed an increasing tendency for ESKD in younger patients (<65 years) with early-stage chronic kidney disease (CKD; eGFR ≥60 mL/min/1.73 m²).
Conclusion
Longer diabetes duration amplifies ESKD risk, particularly as renal function declines. Even in patients with normal renal function, long-standing diabetes significantly increases ESKD risk, while IFG is associated with elevated risk only in younger individuals with early-stage CKD.

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.
