Brain size is a useful parameter describing ontogenic character and function. Despite its potential contribution to functional study and diagnosis of disease, it has been hampered by poor assessment tools in vivo and postmortem changes. Recent development of medical imaging techniques such as MRI and CT enable us to understand brain structures in vivo. Many morphometirc studies of the brain has given us new insights in the field of functional neuroanatomy and neuropsychiatric diseases. In spite of these advances, volumetric data of normal Korean brain is not available yet. As an initial approach to Korean standard brain size, we measured the cerebellar volume between 20 and 80 years old Koreans. The MRI films free from lesions in brain was analyzed and measured by NIH image program. The Korean cerebellar volume were ranged between 86.2cm(3) and 141.3 cm(3) and average male cerebellum volume was significantly larger than that of female[male : 118.2+/-11.2cm(3)] > female : 108.0+/-9.6cm(3), P=0.1021E-07<0.05]. And we could not find volume change according to aging process. This is the first report on normal Korean cerebellar volume and the presence of gender difference in the Korean cerebellar volume. These data will be used for the standard useful in studying cerebellar function and cerebellum associated disorders in the future.

Charcot-Marie-Tooth disease (CMT) is the most common inherited motor and sensory neuropathy. Previous studies have found that, according to CMT patients, neuropathic pain is an occasional symptom of CMT. However, neuropathic pain is not considered to be a significant symptom associated with CMT and, as a result, no studies have investigated the pathophysiology underlying neuropathic pain in this disorder. Thus, the first animal model of neuropathic pain was developed by our laboratory using an adenovirus vector system to study neuropathic pain in CMT. To this end, glycyl-tRNA synthetase (GARS) fusion proteins with a FLAG-tag (wild type [WT], L129P and G240R mutants) were expressed in spinal cord and dorsal root ganglion (DRG) neurons using adenovirus vectors. It is known that GARS mutants induce GARS axonopathies, including CMT type 2D (CMT2D) and distal spinal muscular atrophy type V (dSMA-V). Additionally, the morphological phenotypes of neuropathic pain in this animal model of GARS-induced pain were assessed using several possible markers of pain (Iba1, pERK1/2) or a marker of injured neurons (ATF3). These results suggest that this animal model of CMT using an adenovirus may provide information regarding CMT as well as a useful strategy for the treatment of neuropathic pain.

Background: The purpose of this study was to evaluate the clinical and radiological outcomes of high-flexion total knee arthroplasty (TKA) using Vega Knee System (B. Braun, Aesculap) at a long-term follow-up and to analyze the implant survivorship. Methods: We enrolled 165 patients (232 knees) with a minimum 7-year follow-up after TKA (VEGA Knee System). For clinical assessment, range of motion (ROM), Knee Injury and Osteoarthritis Outcome Score (KOOS), and Western Ontario and McMaster University Osteoarthritis Index (WOMAC) were used. For radiologic assessment, hip-knee-ankle angle, component position, and the existence of radiolucent lines and loosening were used. Survival analysis was conducted using the Kaplan-Meier method. Results: The mean follow-up period was 9.8 years. The mean ROM increased from 124.4° to 131.4° at the final follow-up. The WOMAC score decreased from 38.5 to 17.4 at the final follow-up (p < 0.001). All 5 subscales of the KOOS improved at the final follow-up (all subscales, p < 0.001). Revision TKA was performed in 10 cases (4.3%), which included 9 cases of aseptic loosing and 1 case of periprostatic joint infection. Of the 9 aseptic loosening cases (3.9%), 8 cases (3.4%) were loosening of the femoral component and 1 case (0.4%) was loosening of the tibial component. When revision for any reason was considered an endpoint, the 10-year survivorship was 96.2% (95% confidence interval [CI], 93.9%–98.5%). On the other hand, when revision for aseptic loosening was considered the endpoint, the 10-year survivorship was 96.6% (95% CI, 94.4%–98.8%). Conclusions The Vega Knee System provided good clinical results in the long-term follow-up period. Although the VEGA Knee System showed acceptable implant survivorship, loosening of the femoral component occurred in about 3.4% of the patients. For more accurate evaluation of the survivorship of high-flexion design TKA with a short posterior flange, it is necessary to conduct more long-term follow-up studies targeting diverse races, especially Asians who frequently perform high-flexion activities.

OBJECTIVES: People at ultra-high risk for psychosis have heterogenous character and different long-term outcomes. We divided ultra-high risk subjects into two subgroups by presence of familial history and tried to find different pattern of functional connectivity of the default mode network (DMN) between the two groups in order to examine the effects familial loading. METHODS: Eleven subjects at clinical-high risk (CHR) group with familial history of psychiatric illness and nineteen subjects of CHR group without familial history were recruited. All the subjects were scanned using resting-state functional magnetic resonance imaging. A posterior cingulate cortex was the seed region of the analysis, and the DMN of the both high risk group were analyzed with voxel-wise two sample T test. RESULTS: The CHR group with familial history showed greater functional connectivity in the precuneus area in contrast with the other high risk subjects (peak-level t=5.49, p<0.001). There were no significant differences in total score on the Positive and Negative Syndrome Scale and Scales of Psychosis-risk Syndrome between the two groups. CONCLUSION: The study suggests that the abnormalities of functional connectivity between precuneus and posterior cingulate area may be associated with the genetic vulnerability of high risk trait.

OBJECTIVE: To evaluate the clinical course of the patient who had the gynecologic operation using minolaparotomy. METHODS: We reviewed the chart of the patient who had the gynecologic operation using minilaparotomy in department of obstetrics and gynecology of St. Mary's hospital during Jan. 2000 Sept. 2002. RESULTS: Postopertive diagnosis is myoma (154 cases), adenomyosis (41 cases), ovary cyst (89 cases) and so on. We had performed hysterectomy (225 cases), myomectomy (86 cases), cystectomy or adenexectomy (85 cases) for these patient. There is no significant difference in clinical course between two total hysterecomized groups, one who had the operation history and the other who had not the operation history. CONCLUSION: In gynecological operations, minilaparotomy is the useful methods in any kind of the indication of operation, and show good clinical course.

BACKGROUND: The pathophysiology of migraine is not yet fully understood. Homocysteine acts as an excitatory amino acid in vivo and may influence the threshold of migraine. The previous studies have revealed strong association between the homozygous C677T mutation in the methylenetetrahydrofolate reductase (MTHFR) gene and hyperhomocysteinemia. In this study, we examined the association between both homocysteine and MTHFR C677T polymorphism and headache, such as migraine and tension headache. METHODS: We enrolled 148 headache patients (75 tension headache, 34 migraine with aura [MWA], and 39 migraine without aura [MOA]) and 121 normal controls; checked their fasting homocysteine levels and analyzed for the MTHFR C677T polymorphism. For the multivariate analysis, we used logistic regression to adjust for age and sex. RESULTS: Plasma homocysteine levels were significantly higher in patients with MWA than those in controls (adjusted odds ratio (AOR), 1.12; 95% confidence intervals (CI), 1.02~1.23). The AOR and 95% CI of the MTHFR 677TT genotype was significantly higher in patients with total migraine (AOR, 3.32; 95% CI, 1.30~9.55; p< 0.05) and with MWA (AOR, 4.70; 95% CI, 1.44~15.29; p<0.01) than the controls. However, the AOR was not significant in patients with tension headache (AOR, 0.93; 95% CI, 0.37~2.32) and with MOA (AOR, 2.77; 95% CI, 0.78~9.74). CONCLUSIONS: Our findings suggest that both elevated homocysteine level and the homozygous C677T mutation in the MTHFR gene are associated with migraine with aura.

PURPOSE: Mechanical stapler is regarded as a good alternative to the hand sewing technique, when used in gastric reconstruction. The circular stapling method has been widely applied to gastrectomy (open orlaparoscopic), for gastric cancer. We illustrated and compared the hand-sutured method to the circular stapling method, for Billroth-II, in patients who underwent laparoscopy assisted distal gastrectomy for gastric cancer. MATERIALS AND METHODS: Between April 2009 and May 2011, 60 patients who underwent laparoscopy assisted distal gastrectomy, with Billroth-II, were enrolled. Hand-sutured Billroth-II was performed in 40 patients (manual group) and circular stapler Billroth-II was performed in 20 patients (stapler group). Clinicopathological features and post-operative outcomes were evaluated and compared between the two groups. RESULTS: Nosignificant differences were observed in clinicopathologic parameters and post-operative outcomes, except in the operation times. Operation times and anastomosis times were significantly shorter in the stapler group (P=0.004 and P<0.001). CONCLUSIONS: Compared to the hand-sutured method, the circular stapling method can be applied safely and more efficiently, when performing Billroth-II anastomosis, after laparoscopy assisted distal gastrectomy in patients with gastric cancer.

PURPOSE: To identify the recovery of joint movement and decrease in pain through the radiological findings after open synovectomy for the elbow with rheumatoid arthritis which was not cured by medication. MATERIALS AND METHODS: From 1997 to 2008, the research on open synovectomy for the elbow with rheumatoid arthritis was done in 19 patients with 21 cases whose average follow-up was 12 months. Despite the medical treatment, the indication of operation was towards the patients with Larsen grade I~III rheumatoid arthritis whose joint swelling and pain had not been improved. Also, the indication of operation included the patients with Larsen grade IV who rejected joint replacement or needed to postpone the operation due to young age. Main symptom was pain in all cases; Preoperative flexion contracture and flexion-extension movement on average was 29 degree and 86 degree, respectively.Postoperative radiological and physical examination were done; Visual analogue scale and Mayo elbow performance score were measured. RESULTS: Joint swelling recurred in two cases (9.5%). However, the size of swelling was mild compared to preoperative condition. Preoperative total mean flexion contracture was 29 degree (10~45 degree) and total mean flexion-extension movement was 86 degree (60~135degree). Last follow-up total mean flexion contracture was 18 degree (5~50 degree) and total mean flexion movement was 102 degree (35~150 degree). Statistically, the increase of range of joint movement was not significant. Radiologically, there were 11 cases(52.3%) showing no changes in preoperative and postoperative grade while there were 10 cases(47.6%) with increase in grade. As for VAS score, total mean preoperative score was 5 and postoperative score was 2.3(0~8) showing less pain than the past. After statistical analysis separated by Grade I, II, III and IV, last follow-up of VAS score, Mayo elbow performance score and elbow joint movement showed no statistical difference compared to Larsen grade (p=0.075). CONCLUSIONS: Open Synovectomy for elbow with rheumatoid arthritis can not stop radiological progress, and the increase in range of joint movement is not statistically meaningful. However the operation displays clinical improvement such as decrease in pain and increase in range of joint movement.

We present a rare case of adult intussusception due to cecal lymphangioma. A 30-year-old female was admitted to our hospital with abdominal pain and a palpatable mass on the right lower quadrant. Preoperative radiologic studies by ultrasound and computed tomography showed ileocolic intussusception with a multiseptated cystic tumor as a leading point on the cecum. An ileocecectomy was performed, and the postoperative course was uneventful. Histopathology showed a cecal lymphangioma. Although endoscopic polypectomy or endoscopic mucosal resection is recommended for pedunculated or semi-pedunculated colonic lymphangiomas less than 2 cm in size, it is proper to treat large or symptomatic colonic lymphangiomas with limited a bowel resection or a tumor resection.
