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.

Spiny keratoderma is a rare disorder and consists of multiple tiny keratotic plugs on the fingers and palms, which resemble the spines on a music box. Histopathologically, the lesions show compact columns of parakeratosis, with no granular layer beneath the column and no remarkable changes in the underlying epidermis and dermis. However, it is important to recognize that the disease is associated with internal malignancies. We report a case of spiny keratoderma in a 3-year-old girl, who had no associated underlying disorder.

Colonoscopy is frequently used for lower GI tract screening tests. Although rare, splenic injury may develop in the high-risk patients on anticoagulants or antiplatelet agents. A 78-year-old female visited our hospital complaining of chest pain. She had taken antihyperlipidemic and antiplatelet agent with hyperlipidemia and 20%-stenosis in the left anterior descending artery. She was taken polypectomy after colonoscopy 4 years ago. The next day, after a follow-up colonoscopy for polypectomy, she complained epigastric and left upper abdominal discomfort. Pain intensity was not high, but next day, epigastric pain was increased, so coronary angiography was performed 2 days later using anticoagulants. Coronary angiography showed 40~50%-stenosis in the left anterior descending artery. Another antiplatelet agent was added. After 72 hours on colonoscopy, her pain was localized upper left abdominal area. Abdominal CT showed intracapsular bleeding in the spleen with a small amount of hemoperitoneum in the pelvis. Since her vital signs were stable, she was treated with conservative management. Her pain improved and discharged. One month later, she was taken Abdominal CT. CT showed the size of intracapsular fluid collection in the spleen was increased, but the whole fluid collection was liquidized. 2 weeks later, follow-up sonography showed the size of fluid collection conspicuously was reduced. The case reported herein is a splenic Injury after Colonoscopy in patient on antiplatelet agents.

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.
