Background: Nail can be affected by trauma, infection, and systematic disorders. In particular, the toe nails are exposed to the repeated and cumulative minor traumas, which usually result in thickened, splitted, and discolorated nails. Considering these, it can be inferred that the long second toe can be related to various nail and skin changes by repeated minor traumas such as friction in shoes, but the study or report on this topic hasn’t been done yet. Objectives: The purpose of this study was to introduce various nail and skin changes on long second toe. Methods: We analyzed the kinds of nail/skin changes of 50 patients with long second toe, enrolled at Pusan National University Hospitals (Busan and Yangsan) from 2013 to 2018. Results: There was no significant difference in the incidence of left and right toe and toenail, and 7 (14%) patients presented bilateral distribution. The most common nail change on long second toe was melanonychia (23, 46%), followed by subungual hematoma (15, 30%), onycholysis (2, 4%), subungual hyperkeratosis (2, 4%), onychomadesis (1, 2%), and retronychia (1, 2%). The most common skin change was corn (9, 18%), followed by paronychia (2, 4%). Twenty (20/50, 40%) patients also had other toe or toenail changes. Among them, the most common site was big toe/nail (13, 62%), and the most common change was subungual hematoma (8, 42%). Conclusion: Through this study, the dermatologists can recognize and diagnose the nail and skin changes of long second toe.

Skilled and experienced anestheia is of great importance for patients undergoing orthotopic liver transplantation, because of multiple preexisting medical problems in such patients as well as the intraoperative problems of rapid hemodynamic, metabolic, and coagulation changes. In this study, the intraoperative hemodynamic and laboratory data were analyzed in ten dogs that underwent an orthotopic liver transplantation procedure by veno-venous bypass using Biopump. Liver transplantation can be divided into three distinct periods: stage I, or preanhepatic stage, which begins with the induction of anesthesia and continues until cross clamping of portal vein and IVC; stage II, or anhepatic stage, which begins at the anhepatic time and continues until the donor liver is reperfused by the recipients circulating blood; and stage III, or postanhepatic stage, which begins at the time of reperfusion and continues until the end of surgical procedure. The hemodynamic changes at the time of IVC and portal vein cross clamping were decreases in CVP, PCWP, and pulmonary artery pressure in spite of using Biopump. The significant metabolic alternations during anhepatic stage were decrease in blood glucose levels and increase in blood lactate levels. The more significant hemodynamic changes occurred at the time of reperfusion. Systolic pressure decreased suddenly to 58±6 mmHg and cardiac output decreased to 1.08±0.1l L/min. However heart rate, pulmonary artery pressure, CVP, and PCWP did not change significantly. During stage III, hyperglycemia occurred quite frequently. Significant abnormal coagulation chages could not be found, probably because the dogs were healthy. In conclusion, during anhepatic stage, we have to compensate for alternations of fluid balance. At the time of reperfusion, we should prevent severe hemodynamic changes and treat them immediately if they occur. However, it seems that glucose administration is not necessary to the liver recipient during stage II because there is no significant hemodynamic depression e to hypoglycemia at this time and hyperglycemia occurs later

<P><B>Abstract</B></P><P>Soil organic carbon (SOC) has an important role in improving soil quality and sustainable production. A long-term fertilization study was conducted to investigate changes in SOC and its relation to soil physical properties in a rice paddy soil. The paddy soils analyzed were subjected to different fertilization practices: continuous application of inorganic fertilizers (NPK, N–P–K=120–34.9–66.7kgha<SUP>−1</SUP>yr<SUP>−1</SUP> during 1967–1972 and 150–43.7–83.3kgha<SUP>−1</SUP>yr<SUP>−1</SUP> from 1973 to 2007), straw based compost (Compost, 10Mgha<SUP>−1</SUP>yr<SUP>−1</SUP>), a combination of NPK+Compost, and no fertilization (control). Soil physical properties were investigated at rice harvesting stage in the 41st year for analyzing the relationship with SOC fraction. Continuous compost application increased the total SOC concentration in plough layers and improved soil physical properties. In contrast, inorganic or no fertilization markedly decreased SOC concentration resulting to a deterioration of soil physical health. Most of the SOC was the organo-mineral fraction (<0.053mm size), accounting for over 70% of total SOC. Macro-aggregate SOC fraction (2–0.25mm size), which is used as an indicator of soil quality rather than total SOC, covered 8–17% of total SOC. These two SOC fractions accumulated with the same tendency as the total SOC changes. Comparatively, micro-aggregate SOC (0.25–0.053mm size), which has high correlation with physical properties, significantly decreased with time, irrespective of the inorganic fertilizers or compost application, but the mechanism of decrease is not clear. Conclusively, compost increased total SOC content and effective SOC fraction, thereby improving soil physical properties and sustaining production.</P>

자가면역성 간염은 대개 만성 경과를 가지며, 혈중 자가면역항체와 혈청 글로불린치의 상승, 그리고 조직학적으로 괴사 염증성 변화를 특징으로 하는 질환으로 아직 정확한 병인이 밝혀져 있지 않은 상태이다. 발병연령은 대개 젊은 영자(15-25세)에서 호발한다. 이 질환은 급성 간염의 임상경과를 보일 수 있으나, 심한 급성 간염이나 전격성 간염으로도 나타날 수 있는데, 이 경우 아주 나쁜 예후를 보인다고 한다. 치료는 자가면역성 간염 임상 경과의 다양성이나 병인, 병리기전의 불확실성에도 불구하고 대개 steroid 치료에 반응하는 것으로 알려져 있으며 대개 80%의 관해율을 나타내며 궁극적으로 간경변으로의 진행을 막을 수 있는 것으로 보인다. 저자들은 58세 남자에서 발생한 급성의 경과를 가지고 심한 황달을 동반한 자가면역성 간염을 경험하였기에 문헌고찰과 함께 보고하는 바이다. Autoimmune hepatitis (AIH) is a chronic necroinflammatory liver disorder of unknown cause associated with circulating autoantibodies and a high serum globulin level. The age of onset of AIH show a peak between the age of 15 and 25 years. AIH can develop and be manifested as acute hepatitis, but severe form of acute hepatitis or fulminant hepatic failure has a poor prognosis. Although AIH is likely to progress from chronic active hepatitis to cirrhosis, steroid therapy can control the disease activity, prolong survival, improve the quality of life , and defer liver transplantation. In the present report we describe a 58-year-old man who admitted because of progressive jaundice and fatigue. He was diagnosed with AIH from laboratory test result showing positivity for antinuclear antibodies, anti-smooth muscle antibodies, and negativity for hepatitis viral markers and from liver biopsy. Steroid therapy, oral administration of prednisolone, was effective in improving the liver function test. Following liver biopsy 6 months after onset shows markedly improved necroinflammatory activity.

Background/AimsPost-operative weight loss in patients with gastric cancer lead to a poor quality of life and long-term survival. This study aims to evaluate the effects of gut regulatory hormones on post-operative weight loss in patients with subtotal gastrectomy for gastric cancer. MethodsThis prospective study was conducted for 12 months post-surgery in 14 controls and 13 gastrectomy patients who underwent subtotal gastrectomy for gastric cancer. Serum plasma ghrelin, glucagon-like peptide-1, gastric inhibitory peptide-1, peptide YY, insulin, and homeostatic model assessment for insulin resistance responses to a standardized test meal were recorded at multiple time points before and after gastrectomy at 4 and 12 months. ResultsThe mean weight difference between the pre-operative state and the 4-month period was significantly reduced to 6.6 kg (P = 0.032), but significant weight reduction was not observed from 4 months to 12 months. The plasma levels of glucagon-like peptide-1, gastric inhibitory peptide-1, and peptide YY were significantly increased 4 months postoperatively compared to the pre-operative state (all P = 0.035); however, pre-operative levels and relative changes over a period of 0-4 months of hormones were not correlated with body weight changes. Only the pre-operative ghrelin at peak had a negative correlation with changes in weight reduction in the 4 months after surgery (ρ = −0.8, P = 0.024). ConclusionsSignificant weight reduction was common after subtotal gastrectomy for gastric cancer with a negative correlation pre-operative plasma ghrelin levels. Incretin hormones are modestly but significantly increased after subtotal gastrectomy; however, these changes did not affect the weight changes.

목적 : 2002년 말 중국에서 SARS가 발생한 이후 국내에서도 2003년 10월까지 총 3명의 추정환자, 17명의 의심환자가 보고되었다. 향후 추가적인 SARS의 유행이 우려되는 상황에서, 그간의 SARS 환자 진료에 있어서의 실질적인 준비사항, 진료 현황 등에 대한 조사를 통해 문제점을 파악하여, 향후 더 나은 대비가 될 수 있도록 개선점을 제시하고자 하였다. 재료 및 방법 : SARS로 의심되는 환자를 진료 경험이 있는 병원의료진을 대상으로 2003년 10월에 설문조사를 실시하였다. 설문에는 SARS 환자 진료 시의 실질적인 조치, 진료 현황, 병실, 응급실 및 외래에서의 격리 시설과 준비사항, 보건당국의 관리와 지원에 관한 사항을 포함하였다. 결과 : 대상이 되는 22개 병원 중 17개(17/22, 77.2%) 병원이 설문에 응하였다. SARS 환자를 위한 격리실은 응급실, 외래, 일반병실 및 중환자실에서 각각 9개(9/17, 52.9%), 5개(5/17, 29.4%), 15개(15/16, 93.7%), 4개(4/16, 25%) 병원에서 음압처리가 되어있지 않은 일인실 혹은 다인실이 사용되었고, 1개(1/16, 6.3%) 병원에서만 일반병실에서 음압격리실이 운영되었다. 입원환자의 진찰 시 개인보호구의 착용은 거의 모든 의료기관에서 이루어졌다. 보건당국에서 SARS지정병원의 시설 등을 사전에 확인한 곳은 1곳(1/12, 8.3%)이였고, 14개 병원(14/15, 93.3%)에서는 보건당국에 의뢰한 검사결과를 통하 받지 못하였다. 결론 : 의료기관에서 SARS 환자용 격리실뿐만 아니라 기존의 격리실 설비 등이 미흡하였으며, 특히 중환자실 및 외래의 준비가 더욱 부족하였다. 보건당국의 의료기관에 대한 종합적인 지원이 부족하였고, 병원과의 원활한 연계가 잘 이루어지지 않았다. SARS 만이 아닌 격리를 필요로 하는 질환의 적절한 진료를 위해 향후 병원 시설의 정비와 정부차원에서의 보다 구체적이고 실질적인 대책마련이 필요하다. Background : There was an worldwide outbreak of the Severe Acute Respiratory Syndrome (SARS) originated from China in late 2002. During that period three cases of suspected SARS and 17 cases of probable SARS were reported in Korea. With the concerns about the reemergence of SARS-coV transmission, it is important to be prepared for any possibility. So, this study is aimed to analysis the past measures in managing SARS and propose the amendatory plans to improve the preparedness. Materials & Methods : Questionnaires were collected among clinicians with any experience in managing the probable or suspected SARS cases in Oct. 2003. 17 out of 22 hospitals responded to the questionnaire. The contents in the questionnaire were practical activities, personal equipments, response plans, isolation facilities in emergency centers, outpatient clinics, general wards and intensive care units, and relationship with the public health department. Results : The dedicated isolation rooms in emergency centers, outpatient clinics, general wards, and intensive care units were prepared in 9 (9/17, 52.9%), 5 (5/17, 29.4%), 15 (15/16, 93.7%), and 4 (4/16, 25.0%) hospitals, respectively. Except for one hospital that newly made negative pressure room for SARS, single or multi-bed rooms without airborne infection control were used in all the other hospitals. The personal precaution principles were kept quite well in general wards. Before the designation of SARS hospital by the public health department prior evalution to see if the hospital was suitable for managing SARS was conducted in only 1 (1/12, 8.3%) hospital. The results of laboratory diagnosis were reported back in 1 (1/15, 6.6%) hospital. Conclusions : The isolation facilities which can control airborne infection were almost deficient not only for SARS but also for other respiratory transmissible diseases. For the infection control of transmissible diseases including SARS, more investment is needed on medical facilities and comprehensive support from the public health department required.
