Background and Purpose The present study assessed the effects of cilostazol on LPS-stimulated TLR4 signal pathways in synovial macrophages from patients with rheumatoid arthritis (RA). These effects were confirmed in collagen-induced arthritis (CIA) in mice. Experimental Approach Expression of TLR4, PU.1, NF-κB p65 and IκBα on synovial fluid macrophages from RA patients was determined by Western blotting, and cytokines were measured by elisa. Anti-arthritic effects were evaluated in CIA mice. Key Results Intracellular cAMP was concentration-dependently raised by cilostazol (1-100 μM). Cilostazol significantly suppressed LPS-stimulated increase of TLR4 expression by blocking PU.1 transcriptional activity in RA macrophages. In addition, cilostazol decreased LPS-induced myeloid differentiation factor 88 (MyD88) expression, but not that of TNF receptor-associated factor 6 (TRAF6). Cilostazol also suppressed IkBα degradation and NF-κB p65 nuclear translocation. Moreover, LPS-induced increase of cytokine production (TNF-α, IL-1β) was inhibited by cilostazol, an effect which was accompanied by suppression of IκBα degradation, and NF-κB p65 nuclear translocation. However, expression of anti-inflammatory IL-10 was elevated by cilostazol and forskolin/IBMX. In mice with CIA, post-treatment with cilostazol (30 mg kg-1 day-1) decreased expression of TLR4 in knee joints in association with decreased recruitment of macrophages. Consequently, synovial inflammation, proteoglycan depletion and bone erosion were significantly inhibited by cilostazol treatment. Conclusions and Implications Cilostazol down-regulated LPS-stimulated PU.1-linked TLR4 expression and TLR4/MyD88/NF-κB signal pathways, and then suppressed inflammatory cytokine production in synovial macrophages from RA patients. Also cilostazol markedly inhibited the severity of CIA in mice. © 2012 The Authors. British Journal of Pharmacology © 2012 The British Pharmacological Society.

Hartnup disorder is caused by an inborn error of neutral amino acid transport in the kidneys and intestines. It is characterized by pellagra-like rash, ataxia, and psychotic behavior. Elevated urinary neutral amino acids are the first indicator of the disorder. SLC6A19 was identified as the causative gene in autosomal-recessive Hartnup disorder, which encodes the amino acid transporter B0AT1, mediating neutral amino acid transport from the luminal compartment to the intracellular space. Here, we report on a Korean boy aged 8 years and 5 months with Hartnup disorder, as confirmed by SLC6A19 gene analysis. He manifested seizures, attention-deficit hyperactivity disorder, and mental retardation without pellagra or ataxia. Multiple neutral amino acids were increased in his urine, and genetic analysis of SLC6A19 revealed compound heterozygous mutations, c.908C>T (p.Ser303Leu) and c.1787_1788insG (p.Thr596fsX73), both of which are novel. A novel SLC6A19 gene mutation was associated with late-onset seizures in a Korean patient with Hartnup disorder. © 2010 Elsevier Inc. All rights reserved.

Objectives/Hypothesis: Absorbable packing materials are commonly used after endoscopic sinus surgery (ESS). Cutanplast is a novel gelatin sponge with a powerful hemostatic effect that is rapidly absorbed. The purpose of this study was to investigate the efficacy of Cutanplast in patients following ESS. Study Design: A multicenter, prospective, randomized, double-blind, paired, controlled trial. Methods: One hundred adult patients with chronic sinusitis requiring the same extent of ESS were included. Patients were excluded if they were undergoing septoplasty, turbinate surgery, revision surgery, and taking anticoagulants. Following surgery, one nasal cavity was packed with Cutanplast and the other one with Merocel. Hemostatic properties, patient discomfort while the packing was in situ, patient pain on removal, degree of bleeding on removal, time required to control bleeding after removal, the cost of the pack, and postoperative wound healing were evaluated. Results: Both packs were effective at preventing postoperative hemorrhage. However, Cutanplast was significantly more comfortable while in situ (mean difference, 0.90; 95% confidence interval [CI], 0.75-1.25) and less painful on removal of the pack (mean difference, 1.36; 95% CI, 0.85-1.71). The Merocel pack was associated with significantly more bleeding on removal (mean difference, 1.23; 95% CI, 0.61-2.29), therefore much time was needed to control hemorrhage (mean difference, 1.05; 95% CI, 0.31-1.45). There was no significant difference in the cost of the pack used and outcome measure of wound healing. Conclusions: Cutanplast nasal pack results in significantly less pain and less bleeding compared to Merocel pack.

This study investigated the incidence trends and associated factors of type 1 (T1DM) and type 2 diabetes mellitus (T2DM) in children and adolescents under 15 years of age in Busan and Gyeongnam, Korea from 2001 to 2010.Medical records of newly diagnosed diabetes patients (n=328; 160 males, 168 females) were collected in questionnaire form from 5 tertiary and 42 general hospitals in Busan and Gyeongnam.The average crude incidence rate of T1DM and T2DM was 2.01/100,000 (95% confidence interval [CI], 1.76-2.28) and 0.75/100,000 (95% CI, 0.60-0.92), respectively. The incidence rate ratio (IRR) of T1DM was 1.31 (95% CI, 1.01-1.69), and that of T2DM was 1.97 (95% CI, 1.25-3.11) in the latter half-decade (2006 to 2010) compared to the early half-decade (2001 to 2005). There were gradually increasing incidence trends in both T1DM and T2DM over the 10-year period (P for trend: T1DM, 0.0009; T2DM, <0.0001). Age-specific IRR was highest in the 10- to 14-year-old group, regardless of diabetes type. In particular, a rapid increase in incidence of T2DM occurred in the 10- to 14-year-old group. IRR for females was 1.07 (95% CI, 0.83-1.38) for T1DM and 1.56 (95% CI, 1.01-2.41) for T2DM. IRR for Busan (urban) was 1.41 (95% CI, 1.09-1.83) for T1DM and 1.49 (95% CI, 0.96-2.30) for T2DM.T1DM and T2DM incidence both increased over time in youth under age 15 living in Busan and Gyeongnam; in particular, the incidence of T2DM in adolescents increased more rapidly.

To evaluate the effect of nocturnal dip and blood pressure (BP) variability on paracentral scotoma in early open-angle glaucoma.The present study included 72 early normal-tension glaucoma (NTG) patients and 34 early primary open-angle glaucoma (POAG) patients. Nocturnal dip and weighted standard deviation (wSD) were determined by 24-hour ambulatory BP monitoring (24-hr ABPM). The mean deviation (MD) and pattern deviation (PD) were measured with visual field. Correlations between nocturnal dip and/or BP variability and paracentral scotoma were assessed using Students t-test, Pearsons correlation test, and linear logistic regression analysis.The systolic and diastolic nocturnal dip and paracentral scotoma occurrence demonstrated a statistically significant correlation in the early NTG group (systolic nocturnal dip: p=0.047, diastolic nocturnal dip: p=0.011). In the early NTG group, the subgroup with paracentral scotoma had a greater nocturnal dip than those patients without paracentral scotoma (systolic nocturnal dip: p=0.000; diastolic nocturnal dip: p=0.000). In the early NTG group, the subgroup with paracentral scotoma had higher wSD of SBP than the patients without paracentral scotoma (p=0.003). In the logistic regression analysis of the factors that can affect paracentral scotoma SBP dip and SBP, wSD appeared to significantly affect the occurrence of paracentral scotoma in the early NTG group.Early NTG patients with paracentral scotoma have nocturnal dip and large BP variability. Therefore, in early glaucoma patients, particularly in early NTG with paracentral scotoma, nocturnal dip and BP variability should be assessed with 24-hr ABPM.

Ventricular enlargement following head injury is a frequent finding but cases requiring shunt operation are rare. The incidence and developing factors of post-traumatic hydrocephalus (PTH) have been variously reported, but studies for factors influencing outcomes of shunt operation for PTH are rare. The incidence of PTH requiring shunt operation, causing injuries, and factors influencing outcome of shunt operation need to be identified.In total, 1,142 patients suffering from traumatic brain injury (TBI) between January 2007 and December 2012 were admitted to our department. Of them, 23 patients underwent shunt operation for diagnosed PTH. In this clinical study, we reviewed retrospectively our TBI database and in the 23 patients, we evaluated outcomes with Glasgow Outcome Score just before the operation, at 14 days, 3 months, and 6 months according to initial Glasgow Coma Scale (GCS) score, interval time between shunt operation and trauma, and lumbar cerebrospinal fluid (CSF) pressure.The incidence of PTH treated with shunt operation was 2.01%. Subdural hematoma (SDH) was the most common preceding head injury. The outcomes of shunt operation were not related with lumbar CSF pressure or interval time from trauma, but initial GCS score correlated with the outcome.In present study, 2.01% of TBI patients underwent shunt operation. SDH was the most common preceding injury. Admission GCS score was related to the outcome of shunt operation. However, there were no correlation between the outcome of shunt operation and initial lumbar CSF pressure or interval time of shunt operation after the trauma.

Intrahepatic abscess is an unusual complication of peptic ulcer disease. We present a case of gastric cancer in which the ulcer penetrated into the left lobe of liver with subsequent abscess and fistula formation. Esophagogastroduodenoscopy confirmed ulcers and a fistula opening in the antrum. Abdominal computed tomogram showed a subcapsular liver abscess adjacent to the gastric antrum. Subtotal gastrectomy with curettage of the fistulous tract was performed. The final diagnosis was the signet ring cell gastric carcinoma complicating subcapsular liver abscess. To our knowledge, this is the first reported case in Korea.

Purpose: The aim of this study was to evaluate the prognostic effectiveness of multivisceral resections of organs involved by locally advanced colorectal cancer. Methods: A retrospective study was performed to analyze the data collected for 266 patients who underwent a curative resection for pT3-pT4 colorectal cancer without distant metastasis from January 2000 to December 2007. Of these 266 patients, 54 patients had macroscopically direct invasion of adjacent organs and underwent a multivisceral resection. We evaluated the short-term and the long-term outcomes of a multiviceral resection relative to that of standard surgery. Results: The most common location for the primary lesion was the rectum, followed by the right colon and the sigmoid colon. Among the combined resected organs, common organs were the small bowel, ovary, and bladder. In the multivisceral resection group, tumor infiltration was confirmed histologically in 44.4% of the cases while in the remaining patients, a peritumorous adhesion had mimicked tumor invasion. Postoperative complications occurred in 17.5% of the patients who underwent standard surgery vs. 35.2% of those who underwent a multivisceral resection (P < 0.0001). But the survival rate of patients after a multivisceral resection was similar to that of patients after standard surgery (5-year survival rates: 61% vs. 58%; P = 0.36). Conclusion: For locally advanced colorectal cancer, multivisceral resection was associated with higher postoperative morbidity, but the long-term survival after a curative resection is similar to that after a standard resection. Thus, a multivisceral resection can be recommended for most patients of locally advanced colorectal cancer. © 2011 The Korean Society of Coloproctology.

Objective To evaluate risk factors related to bladder cancer recurrence in patients with pathologically negative pelvic lymph nodes. Methods We reviewed 192 patients who underwent radical cystectomy for muscle invasive bladder cancer between 1999 and 2009. Patients with pathologically positive pelvic lymph nodes and<6-month follow-up were excluded. Clinicopathological parameters including grade, stage, lymphadenectomy type (standard vs. extended), number of nodes removed, margin status, lymphovascular invasion, perineural invasion, presence of carcinoma in situ, ureteral invasion, prostatic urethral invasion, and longest tumor dimension were evaluated. Kaplan-Meier and multivariate Cox analyses were used to evaluate these parameters for 5-year recurrence-free survival (5RFS) and 5-year overall survival (5OS). Results One hundred and fifty-five patients were included in this study. Mean follow-up duration was 36.6 months (12-141 months). Nuclear grade according to 2004 WHO classification (P = 0.006, P = 0.001), perineural invasion (P = 0.041, P = 0.048), lymphovascular invasion (P = 0.005, P = 0.027), and number of nodes removed (P<0.001, P< 0.001) demonstrated differences in 5RFS and 5OS, respectively. In multivariate analysis, 5RFS was related to perineural invasion (P = 0.008; HR: 10.951; 95% CI: 1.891-63.407) and the number of nodes removed (P = 0.038; HR: 1.087; 95% CI: 1.004-1.176), and 5OS was correlated with lymphovascular invasion (P = 0.035; HR: 6.694; 95% CI: 1.143-39.217). Conclusions Perineural invasion and the number of nodes removed were independent risk factors for 5RFS, and lymphovascular invasion was for 5OS in patients with node-negative bladder cancer. © 2011 Springer Science+Business Media, B.V.
