BACKGROUND: Several reports have demonstrated that TGFalpha and EGF are mitogenic for keratinocytes. Whenther its expression on epithelial tumors is a marker of malignancy or signifies an important step in the development of neoplasia is poorly understood. EGF receptors are also present in normal epidermis and epithelial tumors but their physiological roles are not yet understood. OBJECTIVE: Our purpose was to examine the staining patterns of TGFalpha, EGF and EGF receptors on the npithelial tumors of the skin, and to investigate kinetics of expression of EGF receptors. METHODS: We performed immunoperoxidase staining(ABC technique) with monoclonal anti-TGFalpha antibody, polyclonal anti-EGF antibody and polyclonal anti-EGF receptor antibody on the formalinfixed, paraffin-embedded tissue specimens of benign, premalignant and malignant skin tumors. RESULTS: The density of the expression of TGFalpha and EGF was not correlated with the degree of the malignancy of the epithelial tumors and is neither constant in any kind of the tumors. However the infiltrative type of basal cell carcinoma(BCC) is stronger that its solid type on the expression of TGFalpha and EGF. All benign tumors demonstrated a diffuse pattern within tumor lobules. pression of TGFalpha and EGF. All benign tumors demonstrated a diffuse pattern within tumor lobules. Focal TGFalpha immunostaining was seen in three of 10 squamous cell carcinomas(SCC) and four of 10 BCCs. TGFalpha immunostaining was absent from the outermost one to two layers of tumor lobules of all keratoacanthomas. The specimens which increased the expression of TGFalpha and EGF tended to decrease the expression of EGF receptor. CONCLUSION: These data suggest that the density of immunohistochemical expression of TGFalpha and EGF may be not dependent on the differentiation of tumor cells, and the pattern of immunohistochemical expression of TGFalpha can differentiate SCC from benign tumors such as keratoacanthoma. FGF receptor may be occupied by both of TGFalpha and EGF. With the receptors being occupied, a down regulation of the receptors may occur which results in decreased EGF receptor expression.

Artichia with papular lesions is a rare congenit,al disease characteriezed by the association of alopecia and papular lesions. We report a case of atrichia with papular lesions in 12-year-old. Alopecia of the scalp and eye brows were present at birth. Nurnerous papular lesions are presentation the trunk, buttock and inguinal area. The histopathologic iinding of a papular lesion showed ker till-filled cyst, and eruptive vellous hair cyst. The patient showed reticulat.ed hyperpigmentation on the hands and feet in addition to the characteristic feature of atriclia with papular lesions.

This is case report of true class III malocclusion with macroglossia is corrected by glossectomy in 13 years female patient. After orthodontic treatment, the patient is bound to glossectomy because the corrected condition is relapsed to the previous condition due to relatively enlarged tongue compared with the original dental arch. By the interpretation of the cephalogram and model analysis, it is approved that the growth pattern and direction are normal range and mandible is located anterioly to the cranium. The results are follows: 1. We could treat the true Cl III malocclusion. 2. We could prevent the relapse of the treated condition by the surgical intervention, such as partial glossectomy. 3. Sensory, speech, swallowing and so other functions after the operation have been with in normal limit without any serious complications or seguellae.

BACKGROUND: The improved technique for cardiopulmonary resuscitation(CPR) has resulted in the survival of many patient who experienced cardiac arrest. However, mortality in resuscitated patients is high, and the survival rate without brain damage is very low. Various neurological examination models, neuro-imaging techniques, electrophysiological procedures, and biochemical tests have been studied with respect to the detection of cerebral damage and outcome, but an early, reliable prediction of individual outcomes is still uncertain. METHODS: We studied twenty patient who had been in a coma for more than 24 hours after CPR, Somatosensory evoked potentials(SEP) were measured within the first three days after CPR. RESULTS: Of the twenty patients, seven patients(35%) had a good outcome, and thirteen patients(65%) had a bad outcome. Of the eleven patients with loss of the cortical evoked potential's N20 peak, all had a bad outcome. CONCLUSION: SEPs are of great benefit in prognostic evaluation after CPR.

The authors have experienced a case of granulomatous polyp in larynx following endotracheal intubation. The patient had a polyp on the posterior one third of left vocal cord somedays after endotracheal intubation. The microscopic study of the polyp disclosed a granulomatous polyp in larynx.

A 4-year-old girl developed acute motor, sensory impairment, lower abdominal pain and urinary dysfunction after URI. In acute stage of disease, MRI showed diffuse spinal cord swelling and high signal intensity on T2WI below T2 body level. The patient did not improved and one month later, follow-up MRI showed diffuse spinal cord atrophy and syrinx formation as sequelae of ATM on T1WI below T9 level. To our knowledge, this is the first case showing the sequelae of acute transverse myelitis seen in Korea.

BACKGROUND: To describe the fast experience of case-leased advanced cardiac life support(ACLC) course in Korea. METHODS: We have given case-based ACLC course to 13 nurses(6 emergency nurses, 4 coronary care unit muses, 3 professors) and 17 physicians(4 emergency physicians, 12 emergency residents, 1 intem). We performed the case-based ACLS course according to 1992 American Heart Association guidelines and recommendations for advanced cardiac life support by american ACLS instructors(1 pulmonologist, 4 critical care nurses). We performed final theoretical written test and 2 times written survey (immediate and 100th day after the course) about the course. RESULTS: On final written test, all practitioners answered at leasts 70% of the questions correctly. There was no significant difference between nurses and physicians(86.2+/-3.6 of physicians and 82.5+/-6.8 of nurses, p=0.06). 90%of participants considered that case-based advanced cardiac life support was acceptable. 100th day after the course, 93%of participants answered that ACLS course have been helpful on his/her job and also want retraining of ACLS course. 70%of participants considered that ideal ACLS training committee in Korea is the Korean Society of Emergency Medicine. CONCLUSION: Case-based ACLS course is a useful educational method far physicians and nurses in Korea. In the future, we should organize Korean resuscitation committee and then make guidelines for ACLS, and then continuously educate physicians and nurses.

9.Mixed lymphoepithelioma-like carcinoma and adenocarcinoma of the gallbladder.
Korean Journal of Hepato-Biliary-Pancreatic Surgery 2016;20(3):148-151
Lymphoepithelioma-like carcinoma (LELC), an undifferentiated carcinoma with intense lymphoplasmacytic infiltrates, is commonly reported in the nasopharynx and occasionally in other organs. Pure type of LELC has previously been reported in the gallbladder. Mixed type could be reportable in comparison with other organs. Here we present a case of an 83-year-old man with mixed LELC and adenocarcinoma in the gallbladder. To the best of our knowledge, this is the first case of mixed LELC and adenocarcinoma in the gallbladder.
