  • Basal cell carcinoma (BCC) is the most common skin cancer. Ultraviolet radiation exposure and genetic predisposition are known to be the most important etiological factors. Multiple BCC is often associated with genetic familial conditions such as BCC syndrome, basal cell nevus syndrome. We present a case of 54-year-old female who had multiple BCC that had reoccurred. She was completely cured after receiving radio-chemotherapy for leukemia 16 years ago. She had multiple lesions (scalp, left thigh, right popliteal fossa, and right buttock), and had underwent wide excisions of all lesions. All biopsies revealed BCC. Six years later, she had also multiple lesions; left forehead, frontal vertex scalp, parietal vertex scalp, right occipital scalp, and lower abdomen. We performed wide excision. Histopathological examination revealed BCC. She had no signs of any BCC associated syndrome. We report a rare case of nonsyndromic multiple BCC that reoccurred at the new site.

  • From the end of July 2012, several cases of abortion have been happened at the Korean indigenous cattle farm with 124 heads in Chungbuk province, Korea. Serological tests such as Rose-bengal test (RBT) and standard tube agglutination test (STAT) have been performed according to the standard official protocols of bovine brucellosis and 41 cattle turned out to be brucellosis-positive simultaneously. To find out the main factors of brucellosis outbreaks and spreads, additional serological, etiological and molecular investigation were applied. Totally, 11 B. abortus were isolated from 10 cattle's specimens including lymph-nodes and/or testis, and drinking water in cowhouse. In genotyping by multi-locus VNTR assay (MLVA) using 17 loci markers, the present B. abortus isolates were shown all the same pattern, D1 genotype, which has been reported in Gyeonggi and Gangwon province, Korea. These results suggest that the input of brucellosis might come from neighboring farms directly or indirectly, even if by unknown factor and expansion within farm would accelerate by materials related with aborting cows.

  • Cerebral dural sinus thrombosis(CDST) has been described as a rare disease with a variety of patho-etiological factors. The diagnosis of CDST is difficult due to various symptoms and signs, none of which is specific to CDST. But timely diagosis is critical for effective management. The introduction and widespread use of computed tomography(CT), magnetic resonance imaging(MRI) and cerebral angiography made early diagnosis of CDST possible. In particular, MR venography is the most useful tool for establishing a correct diagnosis quickly. In early literature, mortality ranked between 30% and 50% but in more recent series it is between 5.5% and 30%. With the advent of diagnostic and therapeutic tools, early diagnosis and proper management has made the prognosis better. The appropriate therapy for CDST, however, has been the subject of much cortroversy. Individual variations of the venous system and collateral vessels are key factors to decide the proper treatment. In this report, we present two cases with symptomatic CDST treated without open surgical or direct endovascular interventions with good outcome.

  • Purpose: In Oriental medicine, menstruation is a significant index of women's health. Especially high school girls often have various menstrual problems. We think that students who have menstrual problem have some symptoms in relation to an etiological cause. So we had carried out this study to investigate association of DSOM scores and an abnormality of menstruation in oriental medicine. Methods: First we have 2137 high school girls answer to menstrual questionnaire that we made and DSOM, next investigated the pathogenic factor of DSOM which effect dysmenorrhea and menorrhagia using regression model. Logistic regression analysis indicate as follows. Results: 1. In comparison with dysmenorrhea, Qi depression(氣滯), blood stasis(血瘀), dampness (濕), phlegm(痰) is associated positively and liver(肝) negatively. The sensitivity is 64.3%, and the specificity is 75.1%. 2. In comparison with menorrhagia, Blood deficiency(血虛), Qi depression(氣滯), blood stasis(血瘀) is associated positively and liver(肝) negatively. The sensitivity is 53.9%, and the specificity is 76.1%. Conclusion: In this study, that has been carried out to organize the diagnosis of dysmenorrhea and menorrhagia in Oriental medicine, we can see that the disease factors of them were correlated with our Medical theory.

  • Along with language, socialization is a unique feature of the human being. There is a continuous debate regarding whether the development of socialization is innate, and conducted by the environment in the growing process, or the result of the interaction of both aspects. If socialization is the result of the interaction with the environment or is an acquired developmental process, the following question rises. "Is there a 'critical period' for the development of socialization?" Although there are a huge number of studies seeking for treatment and solutions for developmental delay or deficits of socialization, it is very complicated question to answer. Historical figures such as 'Hugh Blair' of Borgue in England, and 'the wild boy of Aveyron' in France, seem to have innate socialization deficits. Nowadays patients with non-verbal learning disorder, social communication disorder, or autism spectrum disorder seem to have genetic defects. On the other hand, Harry Harlow's monkey experiments, hikikomori of Japan, Romanian orphans and patients with reactive attachment disorder seem to display social deficits due to environmental factors. However, it is not easy to clearly draw a line between innate or acquired factors. Therefore, rather than subdividing the diseases for etiological and pathophysiological approach to heterogenous groups with the common denominator of social deficit, and for the research of pathophysiology and treatment development, the authors suggest a comprehensive concept of "social dysfunction spectrum."

  • Objective: This study was designed to evaluate the etiological factors of the PTSD(post traumatic stress disorder) by examining the relationship between severity of physical trauma and subsequent the severity of PTSD symptom in traffic accident related PTSD patients. Method: Subjects were 21 psychiatric inpatients with history of traffic accident related PTSD(DSM-IV criteria), the purpose of evaluation of mental disability and no evidence of organic brain leisons. The severity of physical trauma was assessed by McBride number of nonpsychiatric department and the presence / absence of loss of conciousness. The severity of PTSD symptom was assessed by Hovens' self rating inventory for PTSD. And then we evaluated the correlation between these two factors. And we also evaluated relationship between severity of PTSD symtom and clinical variables. Results : There were no significant relationship between McBride number of nonpsychiatric department severity and symptomatic severity(r= 0.17, p<0.05), the presence / absence of loss of conciousness and symptomatic severity(p>0.05). And significant relationship between symptomatic severity and clinical varibles such as sex, education level, marital status(p<0.05). Conclusions : These data did not support data of previous studies that traumatic severity was correlated with symptom severity but, suggested that other variables affecting the severity of PTSD symptom is more important indirectly. And that the 'trauma' in PTSD is psychological meaning rather than physical meaning is also suggested.

  • This study was carried out to investigate the nutritional status of physically handicapped children with cerebral palsy in order to contribute to their welfare by studying their healthy status, nutrient intake, daily energy expenditure, and living environment. The survey was conducted at two rehabilitation institutions from May 25 to June 30, 1981. A special questionnaire was designed to investigate the living environment. The 24 hr. recall method was used in evaluation the nutrient intake of 67 children. Anthropometric measurement was made of height, weight, chestgirth, upper-arm circumference, and triceps skinfold thickness. The biochemical status of the children with cerebral palsy was assessed with measurement of hemoglobin and hematocrit. The results may be summarized as follows : 1. The children with cerebral palsy, the intakes of all nutrients except vitamin A, thiamin, and ascorbic acid were lower than Korean recommend dietary allowances (1980). They had significantly higher intakes of vitamin A and calcium than the normal children, but the calcium intake was low as 62% of the Korea RDA. 2. All the children with cerebral palsy were very short and low weight in comparison with the accepted standards, but chestgirth was above the accepted standards for Korean school children. 3. The average hemoglobin value was 12.2gm%, hematocrit 39.3%, and mean corpuscular hemoglobin concentration (MCHC) 31.1%. 4. The possible etiological factors of cerebral palsy were, prenatal factors 16%, natal 44.9%, postnatal 27.5%, and unknown 11.6%. Eighty four percent of the children showed their first symptoms within the first year after birth. 5. Thirty percent of the parents said that the handicapped children lead to marital problems, and 84.1% of the parents mentioned that medical expenses for the children influenced their family finances.

  • Background Microvascular anastomosis patency is adversely affected by local and systemic factors. Impaired intimal recovery and endothelial mechanisms promoting thrombus formation at the anastomotic site are common etiological factors of reduced anastomosis patency. Epigallocatechin gallate (EGCG) is a catechin derivative belonging to the flavonoid subgroup and is present in green tea (Camellia sinensis). This study investigated the effects of EGCG on the structure of vessel tips used in microvascular anastomoses and evaluated its effects on thrombus formation at an anastomotic site. Methods Thirty-six adult male Wistar albino rats were used in the study. The right femoral artery was cut and reanastomosed. The rats were divided into two groups (18 per group) and were systemically administered either EGCG or saline. Each group were then subdivided into three groups, each with six rats. Axial histological sections were taken from segments 1 cm proximal and 1 cm distal to the microvascular anastomosis site on days 5, 10, and 14. Results Thrombus formation was significantly different between the EGCG and control groups on day 5 (P=0.015) but not on days 10 or 14. The mean luminal diameter was significantly greater in the EGCG group on days 5 (P=0.002), 10 (P=0.026), and 14 (P=0.002). Intimal thickening was significantly higher on days 5 (P=0.041) and 10 (P=0.02). Conclusions EGCG showed vasodilatory effects and led to reduced early thrombus formation after microvascular repair. Similar studies on venous anastomoses and random or axial pedunculated skin flaps would also contribute valuable findings relevant to this topic.

  • Trauma is frequently implicated in the development of sarcomas, including rhabdomyosarcoma. Rare soft tissue sarcomas have been reported to arise in scar tissue following surgical procedures or thermal or acid burns, at fracture sites, and in the vicinity of plastic or metal implants, usually after a latent period of several years. The authors encountered a case of a rhabdomyosarcoma arising from the forearm crushed by a conveyor belt 11 years ago. Several possible etiological factors for sarcoma development were identified in this patient, including tissue damage and inflammation, as well as the presence of metal implants and the limb's exposure to radiation during multiple imaging tests. After severe soft tissue damage, the occurrence of a sarcoma should be considered and more attention should be paid to the causative factors for sarcoma.

  • Objectives : This research aimed to develop a new etiologic classification for traditional Korean Medicine in order to respond to the social and environmental change. Methods : We reviewed the existing theories on etiological classification for East Asian Medicine thoroughly and discussed the problems and limitations. Based on the experts' consensus, we abstracted disease factors and etiologic items. Results : The disease factors are classified into three parts: the human body, the environment, and the interaction between the human body and the environment. We defined them as the inner factor, the external factor, and the interaction between the inner and the external factors. The inner factor is free from the influence of the environment, and it causes diseases solely from the components of the human body. It is divided into genetic factors. The external factor is defined as a case when a disease occurs due to a factor outside the human body and includes external injuries, environmental pollution, and natural disasters. The interaction between the inner and the external factors is a disease factor that causes diseases by the interaction of the human body and the environment and includes emotions, habits, and social environment. As a result of the analysis, it was possible to see the meanings at a single glance as the scattered and fractional meanings were integrated with focus on medicinal herbs, but the increasing number of analyzed medicinal herbs tended to more and more complicate their relationships, thus, requiring additional work like filtering. Conclusions : The new etiologic classification of Korean Medicine fully reflects the perspectives on life in Korean Medicine while embracing the changes in modem society. Also, by avoiding the usage of ambivalent terms and wrong classification methods, the new classification system constructs intuitive and concise etiology and improves usability in clinical medicine.
