Marjolin's ulcer is a malignant degeneration of cicatrical tissue, especially in chronic burn scar. Since the first description by Jean Nicholas Marjolin(1828), many studies for Marjolin's ulcer have been performed and reported. From 1985 to 1997, we experienced 20 cases in 14 patients diagnosed as Marjolin's ulcer clinically, and we analysed malignant transformation rate, induction period of Marjolin's ulcer and prevention of Marjolin's ulcer, etc. The results are summarized as follows. 1) The sex distribution was predominant in male(64.3%). 2) The most common cause of injury was flame burn(78.6%). 3) The mean age at the time of diagnosis was 45.6 years and the average lag period was 20.6 years. 4) The pathologic types of Marjolin's ulcer were squamous cell carcinoma(57.2%), followed by dyspasia(28.6%), acnthosis and hyperkeratosis(14.2%). 5) The locations of ulcers were frequently on the lower extremity(42.9%), followed by upper extremity(35.7%) and trunk (21.4%). 6) The lymph node involvements were 3 patients out of the 8 patients who were confirmed as squamous cell carcinoma. 7) The modalities of treatment were skin graft (18 cases, 12 patients), myocutaneous flap(1 case, 1 patient), fasciocutaneous flap(1 case, 1 patient).

To investigate results of treatment with essential blepharospasm, patients were evaluated by results of treatment with botulinum toxin A and myectomy operation. Seventy patients of the essential blepharospasm who received local injection of botulinum toxin or orbicularis muscle extirpative surgery were evaluated according to results and complications of the treatment modality over a 7-year period. Fifty-six patients[80%] were primarily treated with botulinum toxin and 14 patients[20%] underwent myectomy operation as the primary treatment. Of the 56 patients, 8[14.3%] were treated later with myectomy operation. In botulinum toxin treatment, the mean subjective improvement was found in 89.2% of the patients, and the mean effective durations of essential blepharospasm were 12.7 weeks. Severity and frequency grades in eyelid spasm were significantly lower after injection[P=.000]. Tearing, dry eye, and headche were the most frequent complications and ptosis was observed in 2 cases[2.0%]. In the orbicularis myectomy operation, 13 patients[59.1%] were carried out through a brow incisions, 1[4.5%] through a blepharoplasty incisions, and 8[36.4%] through both. Fourteen patients[63.6%] had acceptable control of blepharospasm throughout follow-up after the upper lid orbicularis stripping procedure alone. We believe that botulinum toxin is the treatment of first choice because of its higher acceptance rate. Surgery is reserved for botulinum toxin failure. In otherwise fit patients, myectomy is the treatment of first choice.

BACKGROUND: Paederus derriattis is a peculiar linear lesion caused by an insect belonging to genus Paederus, family Staptylinidae, order Coleoptera. The deliberate or accidental contact of crushed coelomic fluid of th insect, on the skin causes acute lesions due to a t.oxin(pederin) being released. OBJECTIVE: The study was nade in order to investigate an epidemic status of the peculiar der matitis and its causative agent of factor prevailing in the midwest area of Kyungpuk province. METHODS: We performed field approaches on 633 cases(M: 303, F: 330) including cases enrolled in a local clinic, teamiring up with a local skin clinician over the 3-month period of August November in 1994. RESULTS: 1. The captive insect causing the present dermatits, was identified as Paederus fuscipes(PF). The epidemic might be attributeid to the climatic conditions with higher temperature than usual during the period of July-eary September in the past year by 3-4degrees C as well as a lower relative humidity. The active temperature zone for PF was presumed to be about 15.5+1.2degrees C to 28.9+1.0degrees C 2. There was the highest p;evalence of 412 cases(65.1%) in early September, followed by mid September, late August, early October and mid August in a small number of cases in decreasing order. The cases were not found after mid October. 3. All age groups were evealy represented. The sex ratio was 1: 1.1 with little difference. The majority of cases lived in Kiriich on city(80.3%), with a lesser outbreak in the neighboring coun ties and Kumi city. 4. The preferred site was the mainly exposed area such as face, neck and extremities. The number of lesion was single(60%) and multiple(40%). The lesion showed a common linear con figuration and acute irritant contact dermatitis consistent with the histologic finding. CONCLUSION: The unusual wiather conditions and poor environmental hygiene help to develop an ecosystem breakdown, which, in turn, sometimes influences the innocuous insects life to be harm ful being on humans, as like outbreak of PF dermatitis.

PURPOSE:Ghrelin is an endogenous ligand of the growth hormone secretagogue receptor, and stomach is the major site of ghrelin secretion. The purpose of this study is to compare the serum ghrelin concentrations between patients with type 2 diabetes mellitus (DM) and normal adults. We studied also whether serum ghrelin levels in the patients with type 2 DM are correlated with body mass index (BMI), serum insulin, lipid profiles, and creatinine levels. METHODS:Forty patients with type 2 DM and forty normal adults were included in this study. We measured heights and weights of the subjects and calculated their BMIs. Blood samples were obtained to measure the ghrelin concentration and their sera were stored at -20degreeC until used. In all subjects, serum ghrelin levels were measured using the commercially available Ghrelin(human) EIA kit. RESULTS:No differences of mean values were detected between the control group and the type 2 diabetic group for age, body weight, BMI, and the levels of serum total cholesterol, triglyceride, HDL cholesterol, and creatinine. But ghrelin level of the type 2 diabetic group (71.1+/-30.5 ng/L) was significantly lower than the control group (139.7+/-36.9 ng/L). In the control group, the ghrelin level showed positive correlation with HDL cholesterol (Pearson's correlation coefficient=0.37, P<0.05). In the diabetic group, the ghrelin level showed weakly positive correlation with insulin concentration. However, there was no significant relationship between serum ghrelin and various parameters in the diabetic patients group. CONCLUSION: In this study, ghrelin concentration in type 2 diabetic patients was lower than that in the control group. In the control group, serum ghrelin concentrations were positively correlated with HDL cholesterol. In the type 2 diabetic group, there was no significant correlation between insulin and ghrelin concentrations.

PURPOSE: The objective of this study was to understand the meaning of experience on community health centers (post) practice of nursing students. METHODS: This is qualitative research using focus groups. Data were collected through in-depth interviews performed from November 10 to December 11, 2009. The focus group interviews were conducted to 22 nursing students on their subjective experiences. The data were analyzed by the Colaizzi's method, in which the meaningful statements were extracted. RESULTS: Seven theme-clusters were identified from fourteen themes and thirty-one sub-themes. The seven theme-clusters were 1) widening of experiences; 2) feeling of warm heart; 3) feeling of satisfaction; 4) feeling of being unfulfilled; 5) difficulties; 6) new awareness; and 7) good memories. CONCLUSION: Through a variety of relationships and self-regulation in community health centers (post) practice, the nursing students may have the feeling of worthiness, new awareness of community nursing, and visions for the future to rebuild.
