Thrombophilia refers to inherited or acquired hemostatic disorders that result in a predisposition to blood clot formation. When combined with the hypercoagulable state that is characteristic of pregnancy, there is an increased risk of severe and recurrent pregnancy complications. Activated protein C resistance caused by factor V Leiden (FVL) mutation is known to be the most common cause of inherited thrombophilia in Caucasian population. FVL mutation has been related to pregnancy complications associated with hypercoagulation, e.g. miscarriage, intrauterine fetal demise, placental abruption, and intrauterine growth retardation. Although the FVL mutation is easily detected using molecular DNA techniques, patients who are heterozygous for this disorder often remain asymptomatic until they develop a concurrent prothrombotic condition. Because there are potentially serious effects of FVL mutation for pregnancy, and because effective treatment strategies exist, early detection and treatment of this condition might be considered.

BACKGROUND/AIMS: Stress has a role in the pathogenesis of functional dyspepsia (FD) and influences food intake in humans and animals. Prokinetic drugs have been used in FD, and some of these drugs reverse the feeding inhibition (FI) induced by acute restraint stress in rats. We aimed to evaluate the effect of DA-9701 on FI induced by acute restraint in rats. MATERIALS AND METHODS: Male Sprague-Dawley rats were divided into 6 groups: Control (no stress), Stress+vehicle, and Stress+DA-9701 at doses of 1, 3, 10, and 30 mg/kg (n=6~7). DA-9701 or vehicle was administered through gastric gavage 45 minutes before stress. After 60 minutes of stress, pre-weighed chow was given and the weight of remaining food was measured 30 and 60 minutes later. The effect of DA-9701 on FI was compared after pretreatment with WAY100635, a 5HT1A antagonist. RESULTS: The restraint stress group had significantly less food intake than the control group. After feeding, rats given 1 and 3 mg/kg of DA-9701 showed increased food intake at 60 minutes, but this was not statistically significant. Rats given 10 mg/kg of DA-9701 showed significantly increased food intake at 30 minutes and 60 minutes (P < 0.05). Interestingly, rats given 30 mg/kg of DA-9701 showed a significant decrease in food intake, similar to that of the vehicle group. The beneficial effect of 10 mg/kg of DA-9701 on FI was abolished by the pretreatment with WAY100635. CONCLUSIONS: Acute restraint stress reduced food intake in rats and pretreatment with DA-9701 improved stress-induced FI.

The objective of study was to compare biomechanical parameters between normal and arch building gait in healthy subjects. A total of 40 feet from 20 healthy adults were evaluated in this study. The participants were asked to walk on a treadmill comfortably at 2 km/hr for 30 seconds. Then, they were asked to walk after making arch building through raising arches with their feet by pulling the big toe toward the heel. Gait parameters such as geometry, center of pressure, maximum force, and maximum pressure were measured in normal and the arch building gait using a gait analysis system equipped with pressure sensor. Arch building gait demonstrated significantly (p<0.01) decreased forefoot maximum force but significantly (p=0.024) increased heel maximum force compared to normal gait. Maximum pressures of the midfoot and heel were also significantly (both p<0.01) increased. However, the maximum pressures of the forefoot were not significantly (p>0.05) different between the two conditions. Geometry, phase, and time parameters were not significantly (p>0.05) different between the two conditions, either. Although forefoot and midfoot maximum force were significantly decreased in arch building gait compared to those in normal gait, the maximum pressure of forefoot was not significantly changed, indicating decreased area of forefoot contact during arch building gait. The arch building gait moves the center of presser to the hind foot and redistributes the contact area, thus changing the distribution of maximum pressure.

Idiopathic hypereosinophilic syndrome (IHES) is a rare disorder defined by persistent blood eosinophilia, evidence of eosinophil-associated organ dysfunction and absence of secondary causes. Eosinophilic infiltration and its mediator release can cause damage to multiple organs. Although IHES can involve every organ system, bladder involvement is rarely evidenced. We recently reported a case of IHES with both bladder and gastrointestinal tract involvement. A 43-year-old woman visited Hallym University Sacred Heart Hospital complaining of urinary frequency, abdominal pain, and diarrhea for several months. Abdominal pelvic computed tomographic scan showed diffuse wall thickenings in her bladder and colon with small pelvic ascites. Laboratory investigation showed a marked peripheral eosinophilia and tissue biopsies confirmed eosinophilic infiltration in the bladder wall, esophagus, and duodenum. The patient was treated with prednisolone and her eosinophilia and symptoms have gradually improved.

OBJECTIVE: The aim of this study was to provide normative data on the Literacy Independent Cognitive Assessment (LICA) and to explore the effects of age, education/literacy, and gender on the performance of this test. METHODS: Eight hundred and eighty-eight healthy elderly subjects, including 164 healthy illiterate subjects, participated in this study. None of the participants had serious medical, psychiatric, or neurological disorders including dementia. Bivariate linear regression analyses were performed to examine the effects of age, education/literacy, and sex on the score in each of the LICA cognitive tests. The normative scores for each age and education/literacy groups are presented. RESULTS: Bivariate linear regression analyses revealed that total score and all cognitive tests of the LICA were significantly influenced by both age and education/literacy. Younger and more-educated subjects outperformed older and illiterate or less-educated subjects, respectively, in all of the tests. The normative scores of LICA total score and subset score were presented according to age (60-64, 65-69, 70-74, 75-80, and > or =80 years) and educational levels (illiterate, and 0-3, 4-6, and > or =7 years of education). CONCLUSION: These results on demographic variables suggest that age and education should be taken into account when attempting to accurately interpret the results of the LICA cognitive subtests. These normative data will be useful for clinical interpretations of the LICA neuropsychological battery in illiterate and literate elderly Koreans. Similar normative studies and validations of the LICA involving different ethnic groups will help to enhance the dementia diagnosis of illiterate people of different ethnicities.

BACKGROUND/AIMS: Therapies of functional dyspepsia (FD) are limited. DA-9701 is a novel prokinetic agent formulated with Pharbitis semen and Corydalis Tuber. We aimed to assess the efficacy of DA-9701 compared with itopride in FD patients. METHODS: Patients with FD randomly received either itopride 50 mg or DA-9701 30 mg t.i.d after a 2-week baseline period. After 4 weeks of treatment, 2 primary efficacy endpoints were analyzed: the change from baseline in composite score of the 8 dyspeptic symptoms and the overall treatment effect. Impact on patients' quality of life was assessed using the Nepean Dyspepsia Index (NDI) questionnaire. RESULTS: We randomly assigned 464 patients with 455 having outcome data. The difference of the composite score change of the 8 symptoms between the 2 groups was 0.62, indicating that DA-9701 was not inferior to itopride. The overall treatment effect response rate was not different between the groups. When responder was defined as > or = 5 of the 7 Likert scale, responder rates were 37% of DA-9701 and 36% of itopride group. Patients receiving DA-9701 experienced similar mean percentage of days with adequate relief during the 4-week treatment period compared with those receiving itopride (56.8% vs 59.1%). Both drugs increased the NDI score of 5 domains without any difference in change of the NDI score between the groups. The safety profile of both drugs was comparable. CONCLUSIONS: DA-9701 significantly improves symptoms in patients with FD. DA-9701 showed non-inferior efficacy to itopride with comparable safety.

Traditionally, urologists recommend an interval of at least 4 weeks after prostate biopsy before radical prostatectomy. The aim of our study was to evaluate whether the interval from prostate biopsy to radical prostatectomy affects immediate operative outcomes, with a focus on differences in surgical approach. The study population of 1,848 radical prostatectomy patients was divided into two groups according to the surgical approach: open or minimally invasive. Open group included perineal and retropubic approach, and minimally invasive group included laparoscopic and robotic approach. The cut-off of the biopsy-to-surgery interval was 4 weeks. Positive surgical margin status, operative time and estimated blood loss were evaluated as endpoint parameters. In the open group, there were significant differences in operative time and estimated blood loss between the <4-week and > or =4-week interval subgroups, but there was no difference in positive margin rate. In the minimally invasive group, there were no differences in the three outcome parameters between the two subgroups. Multivariate analysis revealed that the biopsy-to-surgery interval was not a significant factor affecting immediate operative outcomes in both open and minimally invasive groups, with the exception of the interval > or =4 weeks as a significant factor decreasing operative time in the minimally invasive group. In conclusion, performing open or minimally invasive radical prostatectomy within 4 weeks of prostate biopsy is feasible for both approaches, and is even beneficial for minimally invasive radical prostatectomy to reduce operative time.

PURPOSE: Colorectal cancer (CRC) has a high risk for postoperative thromboembolic complications such as venous thromboembolism (VTE) compared to other surgical diseases, but the relationship between VTE and CRC in Asian patients remains poorly understood. The present study examined the incidence of symptomatic VTE in Korean patients who underwent surgery for CRC. We also identified risk factors, incidence and survival rate for VTE in these patients. MATERIALS AND METHODS: The patients were identified from the CRC database treated from January 2011 to December 2012 in a single institution. These patients were classified into VTE and non-VTE groups, their demographic features were compared, and the factors which had significant effects on VTE and mortality between the two groups were analyzed. RESULTS: We analyzed retrospectively a total of 840 patients and the incidence of VTE was 3.7% (31 patients) during the follow-up period (mean, 17.2 months). Histologic subtype (mucinous adenocarcinoma) and previous history of VTE affected the incidence of VTE on multivariate analysis. There was a statistically significant difference in survival rate between the VTE and non-VTE group, but VTE wasn't the factor affecting survival rate on multivariate analysis. Comparing differences in survival rate for each pathologic stage, there was only a significant difference in stage II patients. CONCLUSION: Among CRC patients after surgery, the incidence of VTE was approximately 3% within 1 year and development of VTE wasn't a significant risk factor for death in our study but these findings are not conclusive due to our small sample size.
