The pneumonia severity index (PSI) and CURB-65 are widely used tools for the prediction of community-acquired pneumonia (CAP). This study was conducted to evaluate validation of severity scoring system including the PSI and CURB-65 scores of Korean CAP patients. In the prospective CAP cohort (participated in by 14 hospitals in Korea from January 2009 to September 2011), 883 patients aged over 18 yr were studied. The 30-day mortalities of all patients were calculated with their PSI index classes and CURB scores. The overall mortality rate was 4.5% (40/883). The mortality rates per CURB-65 score were as follows: score 0, 2.3% (6/260); score 1, 4.0% (12/300); score 2, 6.0% (13/216); score 3, 5.7% (5/88); score 4, 23.5% (4/17); and score 5, 0% (0/2). Mortality rate with PSI risk class were as follows: I, 2.3% (4/174); II, 2.7% (5/182); III, 2.3% (5/213); IV, 4.5% (11/245); and V, 21.7% (15/69). The subgroup mortality rate of Korean CAP patients varies based on the severity scores and CURB-65 is more valid for the lower scores, and PSI, for the higher scores. Thus, these variations must be considered when using PSI and CURB-65 for CAP in Korean patients.

Endoscopic ultrasound-guided celiac plexus neurolysis (EUS-CPN) is a well-established intervention to palliate malignant pain. We report a patient who developed hepatic and splenic infarction and bowel ischemia following EUS-CPN. A 69-year-old man with known lung cancer and pancreatic metastasis was transferred for debilitating, significant epigastric pain for several months. The patient underwent EUS-CPN to palliate the pain. After the procedure, the patient complained continuously of abdominal pain, nausea, and vomiting; hematemesis and hematochezia were newly developed. Abdominal computed tomography revealed infarction of the liver and spleen and ischemia of the stomach and proximal small bowel. On esophagogastroduodenoscopy, hemorrhagic gastroduodenitis, and multiple gastric ulcers were noted without active bleeding. The patient expired on postoperative day 27 despite the best supportive care.

PURPOSE: To compare the levels of serum homocysteine, vitamin B12, vitamin B6 and folate in patients with normal-tension glaucoma, pseudoexfoliation glaucoma and high-tension glaucoma. METHODS: Thirty-two healthy subjects, 35 patients with normal-tension glaucoma, 22 patients with pseudoexfoliation glaucoma and 31 patients with high-tension glaucoma were included in the present study. Fasting venous samples were collected from all the participants. The levels of serum homocysteine, vitamin B12, vitamin B6 and folate were measured. One-way analysis of variance was used for the comparison of homocysteine, vitamin B12, vitamin B6 and folate levels among the 4 groups. RESULTS: The mean homocysteine levels in the pseudoexfoliation glaucoma and high-tension glaucoma group were 17.91 +/- 5.11 and 17.60 +/- 3.89 micromol/l, respectively, which were significantly higher than that of the control group (p = 0.014, p = 0.013, respectively). The mean vitamin B6 levels in the pseudoexfoliation glaucoma and high-tension glaucoma group were 17.67 +/- 14.32 and 17.00 +/- 10.58 nmol/l, respectively, which were significantly lower than that of the control group (p = 0.026, p = 0.008, respectively). CONCLUSIONS: Hyperhomocysteinemia may play a role as a risk factor in the development or progression of pseudoexfoliation glaucoma and high-tension glaucoma.

PURPOSE: To identify the prevalence and clinical features of detrusor underactivity (DU) in elderly men and women presenting with lower urinary tract symptoms (LUTS). MATERIALS AND METHODS: We reviewed 1,179 patients aged over 65 years who had undergone a urodynamic study for LUTS with no neurological or anatomical conditions. DU was defined as a bladder contractility index <100 and a maximal flow rate (Qmax) < or =12 ml/s combined with a detrusor pressure at Qmax < or =10 cmH2O for men and women, respectively. RESULTS: Of the patients, 40.2% of men and 13.3% of women were classified as having DU (p<0.001). Types of clinical symptoms were not significantly different between patients with and without DU. In men, whereas the prevalence of bladder outlet obstruction (BOO) was constant across the age spectrum, the prevalence of DU and detrusor overactivity (DO) increased with age, and 46.5% of men with DU also had DO or BOO. In women, the prevalence of DU also increased with age, and the trend was more remarkable in women aged over 70 years. DU was accompanied by DO or urodynamic stress urinary incontinence (USUI) in 72.6% of the women with DU. Women with DU were found to have lower cystometric capacity and exhibited a greater incidence of reduced compliance than did women without DU. CONCLUSIONS: DU was a common mechanism underlying LUTS in the elderly population, especially in men. One half of the men and three quarters of the women with DU also had other pathologies such as DO, BOO, or USUI.

PURPOSE: To report a case of cataract after long-term use of clonazepam in a young patient, with a similar appearance to cataract induced by other psychotropic agents. CASE SUMMARY: A 37-year-old woman complained of a visual disturbance in both eyes. The best-corrected visual acuity was 0.8 in the right eye and 0.6 in the left eye. Bilateral cortical cataract was observed on slit-lamp examination, and no other ophthalmic abnormalities were found. Potential risk factors for cataract were investigated, including past medical and family history, revealing a 20-year history of oral clonazepam (0.5-1 mg/day), for the neurological diagnosis of "chorea of unknown etiology". Detailed medication history did not reveal long-term use of any other drugs which could have induced the cataract. CONCLUSIONS: Because clonazepam use may induce cortical cataract, regular ophthalmologic examinations are necessary during long-term oral psychotropic therapy.

OBJECTIVE: Recently, the prevalence of gall stone related with metabolic syndrome is increasing in Korea. The aim of this study was to reveal a relationship between components of metabolic syndrome and the development of gall bladder stones. METHODS: Among the subjects who visited a health promotion center of Soonchunhyang University Hospital from March 2009 to March 2010, a total of 5,201 adults were examined. Among them, the final 5,052 (male 3,403, female 1,649) adults were included. Sex, age, body mass index, waist circumference, blood pressure, fasting blood glucose, total cholesterol, triglyceride, high density lipoprotein-cholesterol levels, and the presence of gall stones were measured. Metabolic syndrome was defined by criteria of 2004 American Heart Association/Updated National Cholesterol Education Program Adult Treatment Panel III. Analyses were adjusted by age and sex. RESULTS: This study showed that the prevalence of gall stone was 1.6% and metabolic syndrome was 19.3%. The results didn't show an association between gall stone risk and components of metabolic syndrome. But gall stone risk was increased according to aging, high total cholesterol in the abnormal body mass index group. In normal body mass index group, waist circumference was related with the development of gall stone. Total cholesterol level was related with the development of gall stone in overweight group. CONCLUSION: This study showed total cholesterol levels and waist circumference related with prevalence of gall stone in specific body mass index group.
