PURPOSE: Although the pudendal nerve terminal motor latency (PNTML) is normally used, there is no definite test that accurately reflects the function of the pudendal nerve. This study was undertaken to determine the relative accuracy of the various methods in measuring the function of the pudendal nerve. METHODS: Thirty one female patients (age 51.3+/-15.7) with a defecation disorder (constipation 20, fecal incontinence 11) were evaluated prospectively using a neurophysiologic test and balloon reflex manometry. Five parameters such as the right and left PNTML, anal mucosal electrosensitivity, latency and the amplitude of the rectoanal contractile reflex (RACR) were analyzed statistically for their correlation. RESULTS: There was no significant inter-test correlation among the parameters. However, the intra-test correlations between the parameters such as the right and left PNTML (r=0.9629, P<0.001)/latency and the RACR amplitude (r= -0.3770, P=0.0366) were found to be significant. CONCLUSION: The accuracy of these tests in evaluating the pudendal neuropathy could not be determined. However, because it can be assumed that a measurement of the RACR in addition to RNTML is technically accurate, it there will need to be more study for it to be used as an alternative to a PNTML measurement.

PURPOSE: Although computed tomography (CT) with contrast media (CM) is often performed in patients with renal failure, caution has been exercised due to the supposed risk of contrast-induced nephropathy (CIN). The aim of this study was to examine to true impact of CT with CM on patients with elevated serum creatinine (sCr) levels. METHODS: A total of 216 patients with renal insufficiency who underwent intravenous (IV) contrast CT, with available sCr measurements before and after CT, between January 2008 and March 2012 were included. Patient demographic, biochemical, physiological, and CM data, fluid and drug administration, causes and prognostic factors of CIN, and previously described risk factors were analyzed. RESULTS: The most significant risk factor of CIN in patients with elevated sCr was an acute disease causing pre-renal acute kidney injury (AKI) (p=0.01, odds ratio 4.2), typically related to severe sepsis and septic shock (p<0.001). The factors of fatality related to sCr at day 14 were acute diseases causing pre-renal AKI (p<0.001, p=0.001 respectively). Iodine amounts, chronic kidney disease, prophylactic treatments, and other supposed risk factors did not greatly affect the risk of CIN. CONCLUSION: Although risk factors of CIN are not fully understood, CIN in patients with elevated sCr may be the result of acute progressing diseases, such as AKI in severe sepsis. CIN following IV contrast CT may therefore be less serious than previously thought. We suggest that CT can be performed when needed, even in patients with elevated sCr.

BACKGROUND/AIMS: Prediction of lesions of the proximal right coronary artery (pRCA) through electrocardiogram (ECG) is very important because pRCA occlusion has many complications and a high mortality rate, which has frequently been related with right ventricular infarction. The purpose of this study was to devise a screening tool that takes into account multiple leads from a 12-lead ECG to predict the pRCA lesion. METHODS: A hundred and fifty-eight patients who were diagnosed as acute coronary syndrome and had a pure lesion of RCA or left circumf lex artery (LCX) by ECGs and angiographic findings were enrolled retrospectively. Forty-eight patients with a pure pRCA occlusion were compared to a control group of 110 patients who were diagnosed as having either a pure mid to distal RCA lesion (57 patients) or a pure LCX lesion (53 patients). RESULTS: ECGs of patients in the pRCA group showed more prominent ST depression in lead I (p = 0.001) and ST elevation in V1 (p = 0.002) than in the control group. The combination of ST depression (≤ 0 mm) in I and ST elevation (> 0.5 mm) in V1 was the best diagnostic tool (area under the curve, 0.84). CONCLUSIONS: ST changes in leads V1 and I allow more accurate prediction of pRCA occlusion than other criteria, such as the difference between ST elevation of leads II and III or vector direction and amplitude. These variables could help to screen for right ventricular infarction before performing reverse ECG and predicting prognosis.

Achalasia is an esophageal motility disorder characterized by loss of esophageal peristalsis and impaired relaxation of the lower esophageal sphincter. Patients with achalasia often complain of persistent symptoms for several years before diagnosis. On the other hand, achalasia diagnosed as a sudden esophageal food impaction is uncommon, and no report has been issued on the diagnosis and successful treatment of achalasia in a 95-year-old patient. We report a case of achalasia diagnosed by high-resolution esophageal manometry and timed barium esophagography after food material removal by endoscopy in a 95-year-old woman who visited the hospital due to sudden esophageal food impaction and was successfully treated by endoscopic balloon dilatation.

Objectives: Few studies have reported long-term follow-up after treatment of gastric mucosaassociated lymphoid tissue (MALT) lymphoma. In this single-center study, we investigated longterm treatment outcomes in patients diagnosed with gastric MALT lymphoma. Methods: The study included 80 patients diagnosed with gastric MALT lymphoma, who were followed up at a single center between January 2005 and December 2019 after Helicobacter pylori eradication therapy, radiotherapy, or chemotherapy. We evaluated complete remission, improvement, or recurrence of the lesion. Follow-up over >60 months was classified as long-term follow-up, and the progression-free survival rate was recorded. Results: Following H. pylori eradication treatment, complete remission occurred in 85.9% (55/64) of H. pylori-positive and 50.0% (3/6) of H. pylori-negative patients. All patients with gastric MALT lymphoma who did not respond to H. pylori eradication therapy (100.0% [6/6]) achieved complete remission following administration of local radiotherapy. We observed no deaths on long-term follow-up (>60 months), and the progression-free survival was 101 months. Conclusions In this study, patients with gastric MALT lymphoma showed excellent survival rates, progression-free survival, and prognosis on long-term follow-up. Prospective studies are warranted to determine the long-term prognosis of gastric MALT lymphoma after treatment.

BACKGROUND: The role of beta2-agonist is still important to control bronchoconstriction in asthma. Polymorphisms at aminoacid positions 16 and 27 of the beta2-adrenoceptor gene are associated with asthma phenotype. Glu 27 allele is associated with negatively with bronchial hyperresponsiveness(BHR) in asthmatic subjects and Gln 27 allele is associated positively with IgE levels, and Gly16 Gln27 haplotype is suggested to be positively associated with BHR in a population study. And Gly16 Gln27 haplotypes are positively associated with nocturnal cough in atopic subjects. To evaluate the association between beta2-adrenoceptor polymorphisms as asthmatic phenotypes, the frequency of beta2-adrenoceptor polymorphsisms at 2 sites(Arg16->Gly 16 and Gln 27 -> Glu 27) were examined in asthmatic and normal children. METHODS: Ninty nine asthmatic children and seventy three normal children were enrolled. Asthma phenotypes were determined by physician and bronchial responsiveness and genotypes of beta2-adrenoceptor polymorphisms were determined with PCR based methods. RESULTS: The polymorphisms at aminoacid 16 and 27 of beta2-adrenoceptor gene was not different between asthmatic and normal children. The haplotype frequency of aminoacid 16 and 27 polymorphisms of beta2-adrenoceptor gene was not different between asthmatic and normal children. Haplotypes of aminoacid 16 and 27 was not associated with total eosinophil count, eosinophil %, and total IgE in asthmatic children. Haplotypes of aminoacid 16 and 27 was not associated with PC20, and response of FEV1 after beta2-agonist in asthmatic children. CONCLUSION: beta2-adrenoceptor polymorphisms is not associated with the expression of asthma, atopy, bronchial hyperresponsiveness, and response to beta2-agonist in Korean children.

BACKGROUND: Cerebral infarction as a complication of tuberculous meningitis (TBM) is not uncommon, but has been rarely reported. The purposes of this study were to evaluate the clinical characteristics of cerebral infarction secondary to TBM and investigate the predictive values for cerebral infarction in patients with TBM. METHODS: We prospectively collected patients with TBM for 24 months. Patients were divided into two groups, either patients with stroke or without stroke. We compared the demographic features, clinical, laboratory, and neuroradiologic findings between the two groups. We classified the stroke subtype with neuroimaging findings. RESULTS: The 26 patients were diagnosed as TBM, and 6 patients had complications with cerebral infarction. The neutrophil percentage in the cerebrospinal fluid (CSF) leukocyte were significantly higher in patients with stroke than in patients without stroke (p=0.0098). On initial CT scan, meningeal enhancement was found in 9 patients, and 4 of them complicated with stroke. However, there were no significant differences in the other clinical and laboratory features such as demographic features, interval between meningitis onset time and treatment initiation time, peripheral white blood cell count, and CSF findings. In six patients with stroke, lacunar infarctions and non-lacunar territorial infarctions were found in 3 patients, respectively. In territorial non-lacunar infarction patients, one patient died due to herniation. CONCLUSIONS: We suggest that the possibility of cerebral infarction under the treatment of TBM should be considered, when the patient shows focal neurologic signs, meningeal enhancement on the CT scan and sustained polymorphic CSF pleocytosis.

PURPOSE: The prognosis for patients with liver metastases (LM) from colorectal cancer is significantly influenced by the clinician's decision. Recently, there have been remarkable advances in treatment of LM, so there can be some changes in therapeutic modalities. We performed a comparative study between operated and non-operated groups of patients with LM to analyze the clinical outcome. METHODS: From Feb. 2001 to Feb. 2006, 27 patients with LM underwent a hepatectomy, and 113 patients received non-surgical therapy. thirteen hepatectomized cases among the 27 patients had multiple LM. The outcomes of those 13 patients (Group A) were retrospectively compared to those of the non-operated group (Group B, n=21), which had had potentially resectable LM at the initial diagnosis or after chemotherapy, but didn't undergo hepatic resection. RESULTS: After a median follow-up duration of 31.3 months, the estimated 3-years overall survival (OS) rates were 76.9% and 14.3% in group A and B, respectively (P=0.0001). In the stepwise Cox multivariate regression analysis, factors such as the absence of hepatic resection and a greater diameter of the liver mass independently influenced the poor survival (P=0.005 and P=0.012 respectively). Additionally, two radiologists evaluated the intraoperative ultrasonographic (IOUS) results. IOUS detected new metastatic lesions in 4/13 (30%) patients. There were sub-centimeter metastatic lesions (5~7 mm) and had not been detected in SPIO-enhanced MRI. CONCLUSIONS: Our results compared to palliative chemotherapy suggest that aggressive surgical resection should be performed to increase the survival rate in patients with LM. Additionally, the treatment plan for LM patients should be discussed with the gastroenterololgist, the radiologist, the oncologist, and the surgeon.

Knowledge of clinical demographics and outcomes of mechanically ventilated patients is important but there are few prospectively collected data in Korea. The objective of the present study was to describe the current status of mechanically ventilated patients in Korea as of 2010. We analyzed the data of Korean patients (275 patients in 12 Korean intensive care units [ICU]) participating in a multinational prospective cohort study on mechanical ventilation. The most common indication for mechanical ventilation was pneumonia (23%). Pressure-limited ventilation modes were preferred over volume-cycled ventilation modes. Non-invasive positive pressure ventilation was used in only seven (2%) patients as the initial ventilatory support. Median duration of mechanical ventilation was 7 days and ICU mortality was 36%. The multiple logistic regression model revealed that the Simplified Acute Physiology Score II (SAPS II) score at ICU admission (odds ratio [OR], 1.034; 95% confidence interval [CI], 1.001-1.036; P=0.033), peak pressure (OR, 1.054; 95% CI, 1.016-1.095; P=0.006), and the number of failed organs (OR, 2.132; 95% CI, 1.634-2.781; P<0.001) were independently associated with ICU mortality. This study provides a snapshot of current practice of mechanical ventilation in Korea.

PURPOSE: Effective hemodialysis for a patient with end-stage renal disease (ERDS) is dependent upon a durable, low-morbidity vascular access. Although It is generally agreed that the distal radiocephalic fistula originally discribed by Brescia and Cimino is the most effective primary access constrruction, no consensus exists regarding primary and secondary alternatives for patients with inadequate of failed rediocephalic prodedures. Many options are available, but the relative value of these alternative operations is unclear. Therefore the place of the basilic vein in secondary acccess construction needs to be assessed. We evaluated if the basilic vein can be used to construct a durable, low-morbidity access. METHODS: A native brachio-basilic arterio-venous fistula with superficial transposition has been performed, for lack of usuable vein on 54 forearm in 47 patients from August 1995 to October 1999 (Male: 15, female: 32) with mean age 51 years (26 to 70 years). RESULTS: The main cause of renal insufficiency were: diabetes 27 (57.4%), hypertensive 19 (40.4%), renal tuberculosis 2 (4.3%) and renal cyst 1 (2.1%). The waiting period before vascular access puncture has been 28 6 days. Eight (17.0%) stenosis has been detected and, forearm and/or hand edema occured in three (6.4%); thrombosis in two (4.3%); bleeding in two (4.3%); pseudoaneurysm in one. Through the follow-up periods of 50 months, the primary patency was 80.9% at 12 months and 78.7% at 24 months. CONCLUSION: The brachio-basilic fistula with superficial transposition of basilic vein is a valuable vascular access for diabetes, female old patients, and can remain an alternative method for even younger patients by avoiding the installation of artificial graft after failed forearm arteriovenous fistula.
