Osteochondroma is the most common of primary benign bone tumors. It is characterized by protruding mass from metaphysic of long bone with semitranslucent cartilaginous cap on its surface. This lesion, which has its own growth plate, usually stops growing at skeletal maturity. The multiple variant of osteochondroma, namely the osteochondromatosis, may show various deformities around the joints in its course. In addition, sarcomatous change is sometimes developed. One hundred and twenty one patients were diagnosed as osteochondroma or osteochondromatosis from Jan. 1981 to Dec. 1991, and followed-up for 3.4 years(6months-8years). There were 74 cases of solitary osteochondroma(male : female=1.47 : 1), and 47 cases of osteochondromatosis (male : female=1.61:1). The age at initial visit was averaged 19.5 years(2 years 8 months-58 years). In our experience, common sites were distal femur, proximal tibia, proximal humerus in solitary osteochondroma, proximal tibia, distal femur, distal tibia in osteochondromatosis. Mass with or without pain was the most common chief complaint. Familial histories were noted in 38% of osteochondromatosis. The deformity, which needed correction, were found in 10 among 119 cases ; corrective osteotomy in 7 cases, lengthening with Ilizarov apparatus in 3 cases. The complications such as limitation of motion, sensory disturbance, recurrence, persistent deformity after corrective surgery, epiphyseal plate injury, superficial infection, were noted in 28%. During the follow-up period, there were one case of malignant transformation, and recurrence was identified in 7 cases and three of them were reoperated. Interestingly, progressive deformity was noted in 3 cases postoperatively. And, if the tumor produces no symptom and no functional impairment, we recommend minimizing the indication of surgical intervention. In particular, special attention must be taken in growing children in order to avoid inadvertent complications such as progressive deformity.

3.Research on Psychiatric Treatment by Psychiatrists of Chosun-Governor Hospital and Keijo Imperial University Hospital in Korea during Japanese Colonial Rule.
Journal of Korean Neuropsychiatric Association 2016;55(3):143-157
This review describes the types of psychiatric treatment studied during the Japanese colonial period of 1910–1945 in Korea, known at the time as Chosun. Twenty-nine research papers and abstracts on psychiatric treatment were reviewed, which were published in the Shinkeigaku-zassi (Neurologia), the Seishin-shinkei-gaku zassi (Psychiatria Et Neurologia Japonica) and the Journal of Chosun Medical Association, by faculty members of the department of neuropsychiatry, Chosun-Governor Hospital and Keijo (Seoul) Imperial University School of Medicine. The major research area was biological psychiatry and biological treatment, as Japanese pioneers in psychiatry at that time had introduced German psychiatry into Japan. Professor Kubo published the most papers, followed by Dr. Hattori, Dr. Hikari, and Professor Suits. In Chosun-Governor Hospital, research on prolonged sleep therapy was an active field. In the Imperial University Hospital, malarial fever therapy, sulphur-induced fever therapy, and insulin shock treatment were the most frequent research topics. Some were tried for the first time in the Japanese Empire, which reflected the pioneering position of the university. These achievements are attributed to Professor Kubo. Six papers on psychotherapy were published. Among them, two papers were on persuasion therapy, three papers were case reports of psychoanalytic therapy, and one paper on Freud. However, this psychoanalytic therapy research seemed to be limited trials conducted following literal guidance, and no further development was noted. Generally, research was characterized by simple design, small numbers of subjects, lack of objective evaluation method, lack of statistical treatment, and especially lack of ethical consideration comparing with today's standard.

BACKGROUND: Growth factors play important roles in wound healing. However, the evidence for the effects of growth factors on post-thyroidectomy scars is limited. OBJECTIVE: We performed a prospective study to assess the preventive and therapeutic effect of a multi-growth factor (MGF)-containing cream on post-thyroidectomy scars. METHODS: Twenty-one patients with thyroidectomy scars applied MGF cream twice a day. We assessed the changes in erythema, pigmentation, skin elasticity, and skin hydration status using the erythema index, melanin index, cutometer, and corneometer, respectively. In addition, Vancouver scar scale (VSS) and patient satisfaction were assessed at 10 days after surgery (baseline), 2 weeks, 6 weeks, and 12 weeks after baseline. RESULTS: The mean total VSS scores were significantly lower at 6 weeks (3.24±1.51 vs. 1.91±1.38) and 12 weeks (3.24±1.51 vs. 1.71±1.59) compared to the baseline. The degree of pigmentation was significantly lower at 12 weeks compared to the baseline, and the skin elasticity, and the skin hydration status were significantly higher at 12 weeks compared to the baseline. Over 85% of the patients were satisfied with the use of MGF cream without any adverse effect. CONCLUSION: MGF cream might have additive or supportive effect for scar formation after thyroidectomy.

PURPOSE: To generate a Korean specific brain template, especially in patients with Alzheimer's disease (AD) by optimizing the voxel-based analysis. MATERIALS AND METHODS: Three-dimensional T1-weighted images were obtained from 123 subjects who were 43 cognitively normal subjects and patients with 44 mild cognitive impairment (MCI) and 36 AD. The template and the corresponding aprior maps were created by using the matched pairs approach with considering differences of age, gender and differential diagnosis (DDX). We measured several characteristics in both our and the MNI templates, including in the ventricle size. Also, the fractions of gray matter and white matter voxels normalized by the total intracranial were evaluated. RESULTS: The high resolution template and the corresponding aprior maps of gray matter, white matter (WM) and CSF were created with the voxel-size of 1 x 1 x 1 mm. Mean distance measures and the ventricle sizes differed between two templates. Our brain template had less gray matter and white matter areas than the MNI template. There were volume differences more in gray matter than in white matter. CONCLUSION: Gray matter and/or white matter integrity studies in populations of Korean elderly and patients with AD are needed to investigate with this template.

Background:
The retro superior costotransverse ligament space (RSS) block, reported as a novel target in paraspinal block, involves the spreading of local anesthetics into the thoracic paravertebral space through slits around the superior costotransverse ligament . This blocks not only the dorsal rami but also the ventral rami, achieving a reliable complete sensory blockade. Case: We performed an RSS block at the T5, T7, and T9 levels on both sides for postoperative analgesia in two patients who underwent laparoscopic gastrectomy. Both patients showed complete sensory blockade from T4 to L1 on the anterior, lateral, and posterior chest walls in the recovery room. The resting and dynamic pain scores were 0 at 30 min and 6 h postoperatively. The pain score consistently remained below 3 throughout postoperative period.
Conclusions
The RSS block provided effective postoperative analgesia in laparoscopic gastrectomy through definitive complete sensory blockade.

The role of particulate matter (PM) in health problems including cardiovascular diseases (CVD) and pneumonia is becoming increasingly clear. Polycyclic aromatic hydrocarbons, major components of PM, bind to aryl hydrocarbon receptor (AhRs) and promote the expression of CYP1A1 through the AhR pathway in keratinocytes. Activation of AhRs in skin cells is associated with cell differentiation in keratinocytes and inflammation, resulting in dermatological lesions. Oleanolic acid, a natural component of L. lucidum, also has anti-inflammation, anticancer, and antioxidant characteristics. Previously, we found that PM 10, induced the AhR signaling pathway and autophagy process in keratinocytes. Here, we investigated the effects of oleanolic acid on PM 10,-induced skin aging. We observed that oleanolic acid inhibits PM 10,-induced CYP1A1 and decreases the increase of tumor necrosis factor– alpha and interleukin 6 induced by PM 10,. A supernatant derived from keratinocytes cotreated with oleanolic acid and PM 10, inhibited the release of matrix metalloproteinase 1 in dermal fibroblasts. Also, the AhR-mediated autophagy disruption was recovered by oleanolic acid. Thus, oleanolic acid may be a potential treatment for addressing PM 10,-induced skin aging.
