A dermoid cyst of the head and neck region is a relatively infrequent occurrence and accounts for only 6.9% of all dermoid cysts. Its anatomical distribution is the orbit, floor of the mouth, other midline and nose in the order of frequency. A dermoid cyst of the parotid gland is extremely rare, and due to this and the absence of pathognomonic findings, it is often difficult to diagnose preoperatively. Thus thorough and careful examination including ultrasonic study is needed to evaluate this lesion. It must be differentiated from malignant tumors and other cystic lesions. Dermoid cysts usually recur after simple excision, so it is mandatory to excise it completely with a parotidectomy. This paper presents two cases of parotid gland dermoid cyst with a brief review of the literature.

Cutaneous epidermal cysts are benign lesions commonly experienced in the outpatients department, but the occurrence of a squamous cell carcinoma arising within a cutaneous epidermal cyst is extremely rare. Herein, a case of a squamous cell carcinoma arising from a recurrent epidermal cyst is reported.

To determine whether hyperplastic polyps found in the distal colon are associated with proximal adenomas, and to judge whether patients with distal hyperplastic polyps found during sigmoidoscopy might benefit from full colonoscopy. METHODS: We retrospectively analyzed 2333 consecutive patients who were examined with colonoscopy between January 1991 and December 1994. RESULTS: 247 of 2333 patients (10.6%) had one or more colonic polyps. The prevalence of adenomatous polyps alone was 72.5%, hyperplastic polyps 22.7%, and both 0.52%. The proportion of patients with distal hyperplastic polyps and proximal adenomatous polyps (4.4%) was not significantly different from the proportion of those without distal hyperplastic polyps (1.6%). Patients with distal adenomatous polyps, on the other hand, were significantly more likely to have proximal adenomatous polyps than those without distal adenomatous polyps. CONCLUSIONS: Distal hyperplastic polyps are not strong predictors of risk for proximal adenomatous polyps. Based on the results of this study, we do not believe that finding a hyperplastic polyp during sigmoidoscopy justifies doing a full colonoscopy to search for proximal adenomatous polpys.

BACKGROUND: Automated external defibrillator(AED) represent a major breakdown to permit more widespread application of the principle of early defibrillation. Many recent efforts to improve emergency medical services(EMS) and increase survival rates are simply efforts to get defibrillation to patients as rapidly as possible. AED is major innovation for the prehospital care of ventricular fibrillation cardiac arrest patients. The purpose of this study is to evaluate the course of initial training to three different groups(nurses, firefighters, and EMT trainee) to use AED. METHOD: We studies the efficacy of education of AED to 33 nurses, 15 EMT trainee, and 16 firefighters. Training lasted 75 mins and included 45 mins an overview of defibrillation, protocols for using the AED, and operation of the AED(Laerdal Heartstart 3000),15 mins demonstraion.4 check list was used to grade the performance of cardiopulmonary resuscitation, operation of the AED, and the time required to deliver the first three defibrillations. RESULT: There were no statistically significant differences in performance and time required to deliver an electrical countershock among the groups(p=0.4). To the second test 92fo of all group completed all steps successfully. The step most often foiled was the preparing of the AED for defibrillation. CONCLUSION: In nurses, EMT trainee, and firefighters, it is both feasible and effective to train AED use irrespective of the degree of the trainee.

The purpose of this study is to evaluate the clinical features and efficacy of therapeutic method of 14 pseudotumor patients with radiologically suspected orbital myositis. Retrospective analysis was performed to elucidate correlation with clinical finding, ocular symptom and sign, involved muscles, therapeutic response, and combined ocular diseases. Patients enrolled in this study were 5 men(35.7%) and 9 women(64.3%) (mean age 38.9 years). Two(14.3%) of 14 patients had bilateral disease, 9(64.3%) in the left eye, and 3(21.4%) in the right. The characteristic signs and symptoms included proptosis(35.7%), eyelid swelling(28.6%), periocular pain(28.6%), diplopia(14.3%), and blepharoptosis(7.1%). Radiologically, the medial and superior rectus muscles were affected in equal frequency(64.3%) as were the lateral and inferior rectus muscles(42.9%). Therefore, 11(71.4%) of 14 patients had enlargement of at least 2 muscles. Drug therapy such as ibuprofen, indomethacin, and prednisolone or radiation therapy of pseudotumor with the orbital myositis was less effective in case of patients with the longer duration of myositis than 1 year or involved all the rectus muscles. These patients usually accompany optic neuropathy(35.8%), paranasal sinusitis(28.6%), ocular hypertension(28.6%), scleritis(14.3%), keratitis(14.3%), dry eye(14.3%), and dacryoadenitis(7.1%). In view of the results of this study, when a case presents clinically suspected pesudotumor with the inflammatory reaction or enlargement of extraocular muscle on CT or MRI, it is suggested that the early differential diagnosis, such as orbitoathy of Graves` disease, neoplastic disorder, ateriovenous malformation be made, and that proper treatment of the orbital myositis be institued for good prognosis of disease.

Carcinoid tumors arise from enterochromaffin cells that are located predominatly in the gastrointestinal mucosa. The vast majority of rectal carcinoid tumors are benign and can be safely treated by local excision. Lesions larger than 2 cm and invading the museular wall of the rectum should be considered malignancy and treated by more radical surgery such as abominoperined resection. We report 6 cases of rectal carcinoid tumor, three cases of them were less than 1 cm in size without metastasis. Two of these, small carcinoid tumor were treated with endoacopic polypectomy and one was treated with segmental resection. The others were 2.0 cm or larger in size with regional or liver mestasis. They were treated with segmental resection or electrical fugalization for tumor and transcatheter arterial embilization for liver metastasis or none.

PURPOSE: To compare the clinical outcomes of scleral fixated posterior chamber intraocular lens in vitrectomized eyes according to IOL types. METHODS: Clinical outcomes of 28 eyes of 28 patients who underwent scleral fixated posterior chamber IOL after pars plana vitrectomy and lensectomy were evaluated according to the IOL type used: 19 eyes with PMMA lens (group 1) and 9 with Acrysof(R) foldable lens (group 2) RESULTS: Postoperative BCVA improved or was stabilized in 7 eyes (36.8%) of group 1, and 7 eyes (77.7%) of group 2 (P=0.04). Mean postoperative change in astigmatism was 1.19 +/- 0.79 diopter in group 1 and 0.62 +/- 0.47 diopter in group 2 (P=0.25). Estimated refractive error was -0.76 +/- 0.26 and -0.74 +/- 0.24 diopter in groups 1 and 2, respectively, and postoperative refractive error was -1.31 +/- 1.27 and -1.23 +/- 1.34 diopter, respectively. This showed a slight myopic shift in both groups. There were postoperative complications such as hyphema in 4 eyes (26.3%) in group 1 and in 1 eye (11.1%) in group 2, and transiently increased IOP in 5 eyes (26.3%) and in 1 eye (11.1%), respectively. The other complications that were found in group 1 were glaucoma, retinal detachment, choroidal detachment, and cystoid macular edema. CONCLUSIONS: Scleral fixation using foldable IOL is thought to be a relevant method in vitrectomized eyes, as it showed less postoperative astigmatism change and complications, and better visual outcome.
