Squamous cell carcinoma from the draining sinus of chronic osteomylitis has been recognized as a rare complication. The incidence of this complication is between 0.23% and 1.6% in cases of osteomyelitis. The cause of development of carcinoma at the site of chronic osteomyelitis is not well understood. This is a disease of middle aged men, and tibia is the most common site. Biopsy of squamous cell carcinoma which arises in the proliferating edge of the cutaneous ulcer and invades the bone, should include tissues from all sites of ulcer and bone marrow spaces. Histological diagnosis may be difficult because of preexisting metaplasia and pseudoepitheliomatous hyperplasia. Amputation at the adequate level is the treatment of choice. Four cases of squamous cell carcinoma involving tibia, metatarsal bone or calcaneus are reported with review of literatures.

The purpose of this study is to compared and analyze the shade changes(deltaE)about In-Ceram(R),IPS-Empress(R),OPC(R) by using of the spectrophotometer arising from initial status and before and after cementation of the resin cement mounted on the metal core. We used a couple of statistics such as 'One-Way ANOVA'and Multiple Range Test. We could be able to verify significantly what is being discussed here up to 95%. The results drawn from our research are as follows: 1. At the time of our experiments regarding the initial shapes of all-ceramic and mounting status of all-ceramic on the metal crown(deltaE1), and a comparison of mounting of all ceramic on the metal crown with all-ceramic cemented on the metal core(deltaE2), at the time of shade change of initial shapes and after we cemented on the metal core. (1) no significant difference among all-ceramics was found. (2) no particular difference was found regarding the In-Ceram(R) (3) a significant difference between the deltaE1 and deltaE2 regarding the IPSS-Empress(R) was found (P<0.05). (4) a significant difference between the deltaE1 and deltaE2 regarding the OPC? was found (P<0.05). 2. When we compared the shade changes (deltaE) resulted from before and after the cementation on each of the parts involved of some all-ceramic . we could be able to find shape change increase from incisal third, middle third, and cervical third in that order in In-Cream(R)(spinell), IPS Empress(R) and OPC(R) all. In addition , we could be able to find a siginificant difference between cervical third and incisal third, middle third. (P<0.05) From what we have just seen, we might conclude that there is a significant shade change difference before and after the cementation with respect to IPS-Empress(R)and OPC(R). In addition, we could also be able to find more shade change difference at the cervical third rather than incisal third and middle third depending on the parts involved.

Urine specimens from 60 consecutive patients with hematuria were examined with an autoanalyzer (Coulter counter model S-PLUS JR) to obtain the urinary red cell size distribution curve an mean cellular volume (MCV). Glomerular and nonglomerular red blood cells showed large differences with respect to size distribution, with the peak for glomerular cells at a smaller volume (MCV value 68.40+/-4.32fl) in comparison with the normal size distribution of nonglomerular cells (MCV value 96.78+/-5.76fl). A definite diagnosis was made which correlated with urinary red cell mean cellular volume in of 39 patients (94%) with nonglomerular hematuria and in 20 of 21 patients (95%) with glomerular hematuria. Identification of glomerular (MCV values below 80 fl) and nonglomerular hematuria (MCV values above 80 fl) can be of practical use in the clinical managements of patients. We think that this simple diagnostic work up should be adopted in the routine screening test for patient with hematuria.

Recently we experienced 20 cases of benign prostatic hypertrophy applied with spiral urethral prosthesis. Seventeen patients showed satisfactory voiding just after the procedure and the average flow rate was 12 ml/sec. The remaining 3 patients got well within 2 days. 1 to 14 months of follow-up was done with urine flow rate, voiding symptoms, urine studies, the presence of hematuria and complications, etc. Most of all patients showed urgency initially. but it was disappeared several days. Twelve cases of hematuria and 1 case of stone formation were noted. We believe that implantation of spiral urethral prosthesis (Prostakath TM) is an acceptable procedure for the treatment of benign prostatic hypertrophy in high risk patients to a prostatic operation.

We report a rare case of bilateral transitional cell carcinoma of the ureter associated with acute renal failure. After unilateral percutaneous nephrostomy, right nephroureterectomy was performed without complete resection of the ureteral tumor. Following two cycles of chemotherapy. left upper ureteral obstruction was considerably decompressed with normal renal function.

An outbreak of dermatosis occurred in a livestock fodder factory at Kyongju in May 1994. Authors conducted a questionnaire survey on 60 workers in the factory and a dermatologist examined their skin lesion. Authors also collected mites and identified them. The obtained results were summarized as follows; 1. Twentyeight cases of dermatosis were identified with attack rate of 46.7%. Attack rate was not different by department, age, sex, educational level and employment duration. Attack rate was 67.5% in productive worker and 5.0% in clerical workers (p<0.01) but was not significantly different between departments among productive workers (p>0.05). 2. Three cases among 28 dermatosis cases and one subject among 32 non-cases had a history of same dermatosis last year. Only one of dermatosis cases had a history of dermatosis among family members. History of other skin lesion and allergy was very rare in both cases and non-cases. 3. Skin lesions of the cases were rice-sized erythematous papules or vesicles with a central biting point. Onset date of dermatosis was between May 1 and June 10. Duration was from one day to more than 30 days. Skin lesion was most frequent at the back(75.0%). and also observed at the arms(64.3%). abdomen(60.7%), legs(57.1%), chest(32.1%) and neck (25.0%). Skin lesion was aggravated while workers are sweeping the floor(35.7%), working at the workplace(21.4%) and in bed at night(28. 6%). 4. Total l,637 mites were collected and identified into 3 suborder, 7 families and 17 species. Dermafophagoides farinae was most frequent Nnd most of the species identified were blood sucking mites. Authors concluded that the outbreak of dermatosis was brought about by mite-bites and grain beetle parasitizing Acarophenax tribolii was the most suspected species. Further studies to identify the specific species causing dermatosis and route of import are needed.
