The developement of squamous cell carcinoma from the draining sinus of chronic osteomyelitis has long been recognized as a rare and late complication. The mode of developement of carcinoma at the site of chronic osteomyelitis is not well understood. This, however, is chiefly a disease of middle aged men, and tibia is the most common site. There are two types in this carcinoma; superficial and deep types. In the superficial type obvious presence of fungaiing growth makes diagnosis simple and easily confirmed by biopsy. In the deep type the diagnosis is difficult clinically, but the features most frequently described are an increase in pain and discharge with swelling and hemorrhage. Amputation at the adequate level is the treatment of choice. Three cases of the disease involving one left femur, and two left tibiae are reported with review of literature.

Hypertensive encephalopathy is an acute clinical syndrome that shows central nerve dysfunction with sudden and marked elevation in blood pressure. But its pathophysiologic mechanisms, clinical courses and prognosis are still not clear. In order to study clinical manifestations and response to treatment in patients with hypertensive encephalopathy, we reviewed 45 patients with hypertensive encephalopathy who were admitted in Dept. of Internal Medicine, National Medical Center, from January 1975 to December 1984. The following results were obtained: 1) The ratio of male to female was 1.1:1. The peak age of incidence was in the 6th and 7th decade with mean age of 57.5 years. 2) Among 45 patients, only 29 had known history of hypertension and the average duration of hypertension was 8.1+/-3.6 years. 3) The most common sympotm was severe headache (68.9%). And altered consciousness, nausea and/or vomiting, focal neurologic signs and visual disturbance were also common symptoms in decreasing order of frequency. 4) Funduscopic examination showed hypertensive retinopathy in 20 of 24 (91.7%) patients and lumbar puncture revealed increased CSF pressure in 12 of 20 (60%) patients. 5) In most patients, the mean interval to symptomatic improvement was 2.1 days after administration of anti hypertensive agents, but in 6 patients with initial mean arterial blood pressure above 170mmHg, 4 patients showed delayed response and 2 patients were expired.

Pharmacological mydriasis can cause an acute elevation of intraocular pressure without obstruction of angle. A prospective study of 80 normal Korean subjects(149 eyes) and 20 Korean primary open angle glaucoma patients(49 eyes) was performed in order to obtain and compare effects on intraocular pressure, pupil size and aqueous floater by phenylephrine, Mydrin-P(R) and cyclopentolate and to investigate wheather intraocular pressure elevation occurs also in Korean eyes after pupil dilation. Significant pressure elevation(6mmHg or more) was rare in normal subjects while incidence of 25% with Mydrin-P(R) and 50% with cyclopentolate occurred in primary open angle glaucoma patients. Thus, stronger cyclopegics induced intraocular pressure elevation more frequently. Statistically significant correlation between intraocular pressure elevation and aqueous floater did not exist in primary open angle glaucoma patients but only existed with cyclopentolate in normal subjects. Maximum mydriasis by phenylephrine, Mydrin-P(R) and cyclopentolate occurred in 60, 90 and 90 minutes respectively. There is a potential hazard of routine dilation of eyes with cycloplegic agents in primary open angle glaucoma patients in both Korean and occidental eyes.

The importance of vegetables as a allergen for the development of hand eczema has been a matter of debate. The aim of this study was to evaluate the clinical manifestations of hand eczema and to investigate the role of vegetables in the hand eczema of Korean housewives. In this study, clinical evaluatons and patch tests with Hollister-Stier standard allergens and 22 vegetable allergens wer performed in 32 patients with housewife's hand eczema. The results are summarized as follows : 1. The prevalence was highest in fourth(59.4%) and third(25.0%) decades of life and the peak age of onset was third(53.1%) and fourth(31.3%) decades. 2. Only 3 of 32 patients(9.4%) had past histories of atopic dermatitis ; however, childrens of 12 patients(37.5%) had atopic dermatitis. 3. The common skin signs were fissuring(90.6%), scaling(78.1%), erythema(75.0%), hyperkeratosis(71.9%), lichenification(62.5%), and vesicle(43.8%) in descending order. 4. The common aggravating factors were soap or detergent(93.8%), water(90.6%) and rubber glove(25.0%). 5. The most common involved areas of hand eczema were fingers including fingertips and fingertips only. 6. The results of patch test using vegetable allergens with 10 normal controls were all negative. Of the 32 patients with hand eczema, 13(37.5%) showed positive patch test with standard allergens and 5(15.6%) showed positive with vegetable allergens. 7. Among 30 standard allergens, cinnamic alcohol(9.4%). potassium dichromate(9.4%), nickel sulfate(6.3%), and wool wax alcohol(6.3%) were the common allergens which showed positive reactions. Of the 22 vegetable allergens, garlic, Chinese cabbage juice, Chinese cabbage extract, cucumber juice, spinach extract, potato juice showed weak positive reactions in only one patient(3.1%) respectively. From the above results contact sensitivity to vegetables is not significant in Korean housewives with hand eczema.

Papillary carcinoma of the thyroid is a well differentiated neoplasm and usually has a good prognosis. However, a subset of morphologically distinct papillary carcinoma has bad prognoses. The tall cell variant of papillary carcinoma (TCPC), characterized by tall columnar cells with a height at least twice the width, is the one of these. In order to differentiate TCPC from usual papillary carcinoma (UPC) in terms of prognosis, we performed immunohistochemical studies for the expression of p53, bcl-2 and Leu-M1 proteins in 25 cases of TCPC, 26 cases of UPC and 14 cases of poorly differentiated, solid type papillary carcinoma (SPC) with an analysis of clinical parameters. The nuclear expression of p53 was noted in one case each of UPC and TCPC. The cytoplasmic p53 expression of TCPC, UPC, and SPC was observed in 17/25 cases (68%), 14/26 cases (54%), 3/14 cases (21%), respectively. bcl-2 expression was 19/25 cases (76%), 18/26 cases (69%), 5/14 cases (36%), and that of Leu-M1 was 21/25 cases (84%), 18/26 cases (69%), 4/14 cases(29%), respectively. There were no statistical significance in the expression of those immunoproteins among these three groups (p>0.05). The p53 protein was consistently expressed in the cytoplasm rather than nucleus in this study and was very well correlated to bcl-2 positivity (p<0.01). There were no statistical significance in any clinical parameters examined among these three groups (p>0.05). In conclusion, TCPC can not be separated from UPC as a distinct entity in this study and the cytoplasmic expression of p53 protein provides another mechanism of p53 inactivation in tumorigenesis of the thyroid papillary carcinoma, possibly by bcl-2 related mechanism.

BACKGROUND: Pachydermoperiostosis(PDP) is a rare genetic disease characterized by pachydermia, periostosis, arthralgia and finger clubbing. The pathogenesis of this disease is still unknown, but the concept that platelets and endothelial cells may play a major role in the developement of pachydermia is widely accepted nowadays, It is also suspected that several serum growth factors stimulate proliferation of soft tissue. OBJECTIVE: The purpose of this study was to investigate the pathogenesis of pachydermia in patients with pachydermoperiostosis through evaluating whether the fibroblasts from these patients have a higher proliferation rate than those from controls or whether the proliferation rate of those cells are affected by certain serum growth factors. METHOD: At first, we evaluated the proliferation rate of fibroblasts from patients and corntrols by the MTT colorimetric assay, and then the proliferation rate of fibroblasts from the prepuce of newborn infants under several conditions of media containing uncentrifuged patients serum, centrifuged patients serum, uncentrifuged control serum, or centrifuged control serum. RESULTS: The proliferation of fibroblasts from patients skin was slower than the control fibroblasts and fibroblasts derived from uninvolved skin of patients. The statistically significant highest proliferation rate was observed when fibroblasts were cultured in the uncentrifuged patients serum contained media and the order of proliferation was as follows: centrifuged patients serum, uncentrifuged control serum and centrifuged control serum condition at 20%, 10%, and 1% respectively. CONCLUSION: These results suggest that patients fibroblasts do not proliferate in vitro at a higher rate than control firoblasts. Fibroblasts in PDP may only play a role as target cells and certain serum factors are responsible for the pathogenesis of PDP.

A case of laryngeal carcinoid in a 54-year-old Korean female is reported and discussed. This tumor is extremely rare in the larynx and there have been just over twenty cases reported in the literature to date. The case showed an initial histologic finding of epithelial dysplasia and was finally confirmed to be a carcinoid tumor. Laryngeal carcinoids are often atypical histologically and may be misdiagnosed as undifferentiated carcinoma. An electron microscopic study revealed neurosecretory-type granules. Although the patient underwent a total laryngectomy and radical neck dissection, multiple hepatic metastasis was noted postoperatively.

Median raphe canal is an uncommon disease and represents a defect abnormality of the male genitalia. It occurs along the ventral median raphe from the glans penis to the anus. Histologically the canal is lined by stratified squamous epithelium which dose not communicate with the urethra. Surgical excision is the treatment of choice. Recently we observed a 25-year-old male patient who had had a median raphe canal located in the ventral aspect of penis.

Glucocorticoid hormones have been identified as one of the B cell activating signals necessary in IgE synthesis in the presence interleukin 4(IL-4). One question to be addressed in IgE synthesis is whether there is difference between atopics and non-atopics. In the present study, we aimed at looking the different effects of interleukin 4(IL-4) and hydrocortisone(HC) in IgE synthesis by peripheral blood monounclear cells (PBMCs) from 12 atopic patients and 6 non-atopic controls. PBMCs were cultured with IL-4 and/or HC for 14 days, and net IgE production was measured in the supernatant. Significant spontaneous IgE production by PBMCs was oberserved only in atopics. IL-4 increased net IgE synthesis by PBMCs from both atopics and non-atopics by similar amounts, whereas HC had that effect only in some atopics who showed high spontaneous IgE production. HC acted synergically with IL-4 in a narrow range of concentration which is individually different. This effect was more remarkable in subjects with low total serum IgE levels. These data suggest that atopic patients may have larger numbers of B cells committed to produce IgE, and that the effect of HC on IgE synthesis in vitro may be due to the priming effect of IL-4 in vivo.
