PURPOSE: The purpose of this study is to illustrate MR patterns of bone marrow of calvarium and vertebral body in normal subjects according the age distribution and to understand the course of the fatty replacement from red marrow. METHODS AND MATERIAL: We retrospectively evaluated MR examinations of the calvaria(n=71), cervical spine(n=71), thoracic spine(n=65), Imbar spine(n =68) in subjects without bone marrow abnormality whose age ranged 3 weeks to 74 years. Three distinctive patterns were categorized on Tl-weighted images of the skull. In pattern 1, uniformly low signal intensity with or without very small areas of high intensity in frontal and occipital bones is noted. In pattern 2, frontal and occipital bones have uniformly high signal intensity, and patchy area of high intensity appears in parietal bone. In pattern 3, the entire skull has uniformly high signal intensity. In the spine, four patterns were categorized on Tl-weighted MR images. In pattern 1, the vertebral body has uniformly low signal intensity except for linear areas of high intensity superior and inferior to basivertebral vein. In pattern 2, bandlike and triangular areas of high signal intensity are found in the periphery. Pattern 3 and 4 have diffusely distributed areas of high signal intensity; pattern 3 consist of numerous indistinct dots measuring a few millimeter or less, and pattern 4 consist of fairly well marginated areas ranging in size from 5 to 1.5cm. RESULT:In the calvaria, 73% of pattern 1 were younger than 20 years, pattern 2 were evenly distributed, and 86% of pattern 3 were older than 40 years. In the spine, 87% of pattern 1 were younger than 40 years, 72% of pattern 3 were in 40 to 50 years, and 87% of pattern 4 were older than 50 years. Pattern 2 were evenly distributed in the cervical and thoracic spine, but in the thoracic spine 62% were younger than 30 years. CONCLUSION:It is concluded that younger age group shows mainly pattern 1, whereas elderly group has pattern 3 or 4 in the calvarial and vertebral body marrow. This suggests that conversion to fatty marrow begin locally and progress diffusely with age.

PURPOSE: The study investigated clinical features of patients who underwent thyroid surgery, with and without Hashimoto's thyroiditis. METHODS: We retrospectively reviewed the medical records of 150 patients who underwent thyroid surgery at the Department of Surgery, Wallace Memorial Baptist Hospital, between January 2007 and December 2008. Patients were divided into two groups according to occurrence or non-occurrence of Hashimoto's thyroiditis, and analyzed them for age, sex, day of hospitalization, duration of drain keeping, operation time, and post-operative complications, including recurrent laryngeal nerve injuries, hypoparathyroidism, hypocalcemia, and adjacent structure injury. There were 24 lobectomies and 126 total thyroidectomies. RESULTS: Operation time was longer for patients with Hashimoto's thyroiditis. There was little difference between the two groups with respect to day of hospitalization, duration of draining, or post-operative complications. Of the total thyroidectomy cases without Hashimoto's thyroiditis, 36 patients (37.5%) had transient hypocalcemia and four (4.2%) had permanent hypocalcemia. Of the cases with Hashimoto's thyroiditis, 13 patients (38.2%) had transient hypocalcemia and three (8.8%) had permanent hypocalcemia. Patients undergoing thyroid surgery with Hashimoto's thyroiditis had longer operation times due to increased angiogenesis and fibrosis. No difference was shown for other clinical features or post-operative complications. CONCLUSION: The data strongly indicate that meticulous hemostasis and careful surgical technique, along with an understanding of anatomic variation and surgical experience, leads to a low late of complications following thyroid surgery, even for patients with Hashimoto's thyroiditis.

Purpose: This study examined the research trends using G-power centered on major Korean registered sites and presents the research trends of studies with a high level of evidence.Method: This study selected three research journals listed in the Korea Research Foundation among physical therapy journals in the field of physiotherapy. The selected papers were classified according to the following: 1) study type, 2) study level, and 3) quality of the study.Result: Sixty-nine articles were selected and classified according to the study type. The musculoskeletal system, central nervous system, and others comprised 73.91% (n=51), 17.39% (n=12), and 8.7% (n=6), respectively. The results were classified into 62 experimental studies, four observational analytic studies, and three descriptive studies. The experimental studies included 22 randomized controlled trials (level 2) and 40 non-randomized trials (level 3). Sixteen randomized controlled trials were classified for a qualitative evaluation, and 12 papers with a score of six or more (good) were found. Conclusion Many high-level studies were found in G-power, and the quality of the study was also good. Therefore, the effective number of samples obtained using G-power is one of the ways to enable high-quality research.

Dengue fever is an important health problem for international travelers to all endemic areas. The steadily increasing numbers of tourists visiting endemic areas raise the risk of exposure, and imported dengue cases are increasingly observed in nonendemic area. Dengue has a wide spectrum of clinical presentations, often with unpredictable clinical evolution and outcome. While most patients recover following a self-limiting, non-severe clinical course, a small proportion progress to severe disease such as dengue hemorrhagic fever or dengue shock syndrome. Therefore, it is important to suspect dengue fever in every febrile patient returning from the tropics. Whenever it is suspected, a quick diagnosis and adequate managements are essential to avoid complications. We report two cases of imported dengue fever in Korean children presenting with fever, headache, nausea, and rash.

The hypotensive effect and side reactions of Buterazine were evaluated in 21 patients with essential hypertension. The results were as follows; 1) Before medication and after 2 and 4 weeks of medication, the over all average systolic and diastolic pressure were 188+/-23/112+/-7, 168+/-13/101+/-17, and 158+/-12/95+/-8mmHg, respectively. After 2 and 4 weeks of medication, the over all average systolic pressure decreased by 20 and 30mmHg(P<0.005, P<0.001), and the over all average diastolic pressure decreased by 11 and 17mmHg(P<0.025, P<0.001), respectively. In 69% of all cases, marked or moderate degree of hypotensive effect was observed. 2) There was no significant changes in heart rates before and after treatment. 3) In 84% of all cases, improvement of symptoms were observed. 4) There was no side effects which required discontinuing the treatment, except 2 cases which discontinued the medication.
