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.

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.

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.

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.

Mechanical obstruction of the common hepatic duct includes the following causes; choledocholithiasis, sclerosis, cholangitis, pancreatic carcinoma, cholangiocarcinoma, postoperative stricture, primary hepatic duct carcinoma, enlarged cystic duct lymph nodes, and metastatic nodal involvement of the porta hepatis. Partial mechanical obstruction of the common hepatic duct caused by impaction of stones and inflammation surrounding the vicinity of the neck of the gallbladder had been reported on the “syndrome del conducto hepatico” in 1948 by Mirizzi. Nowadays, this disease was named by Mirizzi syndrome. Mrizzi syndrome is a rare entity of common hepatic duct obstruction that results from an inflammatory response secondary to a gallstone impacted in the cystic duct or neck of the gallbladder. It results from an almost parallel course and low insertion of the cystic duct into the common hepatic duct. In a variant of Mirizzi's syndrome, the cause of the common hepatic duct obstruction was a primary cystic duct carcinoma rather than gallstone disease. A 71-year-old man was admitted with a four-day history of right upper quadrant abdominal pain. Past medical history was unremarkable. On physical examination, the patient had a temperature of 38℃, icteric sclera and right upper quadrant tenderness. Pertinent laboratory findings included WBC 18,000/cm3; albumin 2.6 g/dl (normal 0-1) with the direct bilirubin, 4.4 mg/dl (normal 0-0.4). Ultrasonography revealed a dilated extrahepatic biliary tree. ERCP showed that the superior margin was angular and more consistent with a calculus causing partial CHD obstruction (Mirizzi syndrome). At surgery a diseased gallbladder containing calculi was found. In addition, there was two calculi partially eroding through the proximal portion of the cystic duct and compressing the common hepatic duct. A cholecystectomy and excision of common bile duct was performed, with Roux-en-Y hepaticojejunostomy. The postoperative course was uneventful.

PURPOSE: Several naturally-derived biopolymers have been introduced as implantable biomaterial for tissue reconstruction, and some of them are already being applied in various clinical fields. They serve as backbones for the regeneration of damaged tissue. It is well known that growth factors play an important role in this process and some of the naturally- derived biopolymers were known to contain several kinds of growth factors, but there are few reports about any growth factors in the various biopolymers. We tried to confirm the existence of growth factor receptors and neurogenic factors through the expression of the mRNA from the biopolymers. MATERIALS AND METHODS: Bladders were harvested from adult pigs. Vesical submucosa was obtained with using mechanical decellulization technique. Acellular matrices were made from pig bladder with using a cell lysis technique, and they were examined by performing scanning electron microscopy. Expression of the mRNA of vascular endothelial growth factor (VEGF) receptor, fibroblast growth factor (FGF)-1 receptor, neuregulin and brain-derived neurotrophic factor (BDNF) in the acellular matrix and the submucosa of porcine bladder were examined for via reverse transcription- polymerase chain reaction (RT-PCR). RESULTS: The ultrastructure of the acelluar matrix shows collagen fibers with many pores. The mRNA's of VEGF receptor, FGF-1 receptor and neuregulin were expressed in the porcine vesical acellular matrix, whereas BDNF was not expressed. On the other hand, none of the mRNA's examined was expressed in the porcine vesical submucosa. CONCLUSIONS: This study's results shows that several growth factors are detected in the acellular matrix of the porcine bladder. These growth factors may play an important role for the growth of tissue when it is implanted in vivo. It is also assumed that there are more growth factors in naturally-derived biopolymers, and it would be useful to investigate the undefined components of naturally-derived biopolymers for developing new and advanced polymers.
