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.

BACKGROUND: The intrathecal (IT) administration of glycine or GABAA receptor antagonist result in a touch evoked allodynia through disinhibition in the spinal cord. Glycine is an inhibitory neurotransmitter that appears to be important in sensory processing in the spinal cord. This study was aimed to evaluate the effect of glycine-related amino acids on antagonizing the effects of IT strychnine (STR) or bicuculline (BIC) when each amino acid was administered in combination with STR or BIC. METHODS: A total of 174 male ICR mice were randomized to receive an IT injection of equimolar dose of glycine, betaine, beta-alanine, or taurine in combination with STR or BIC. Agitation in response to innocuous stimulation with a von Frey filament after IT injection was assessed. The pain index in hot-plate test were observed after it injection. The effect of it muscimol in combination with str or bic were also observed. RESULTS: The allodynia induced by STR was relieved by high dose of glycine or betaine. But, allodynia induced by BIC was not relieved by any amino acid. Whereas the STR-induced thermal hyperalgesia was only relieved by high dose of taurine at 120 min after IT injection, the BIC-induced one was relieved by not only high dose of taurine at 120 min but also low dose of glycine or betaine at 60 min after IT injection. The BIC-induced allodynia and thermal hyperalgesia was relieved by IT muscimol. CONCLUSIONS: This study suggests that IT glycine and related amino acids can reduce the allodynic and hyperalgesic action of STR or BIC in mice.

PURPOSE: Spiculation pathologically correlated with irregular fibrosis, localized lymphatic spread of tumor, or an infiltrative growth pattern of tumor, and the spiculation was Observed in malignant mass. But the spiculation was also observed in benign mass, particularly in tuberculoma. We retrospectively reviewed the length of spiculation under the hypothesis that the length of spiculation could be one of differential diagnostic points between lung cancer and tuberculoma. MATERIALS AND METHODS: We studied thirty seven patients (27 men and 10 women) ranging in age from 35 to 80 years (mean, 60 years). Analysis of spiculation included (a) the number of spicules (b) the mean length of spicules (c) the mean length of the longest spicule (d) the percentage of the mean length of spicules to the longest diameter of mass (e) the percentage of the mean length of spicules to the shortest dia, meter of mass. RESULTS: The mean length of spicules of tuberculoma was 13.8 mm (S. D. 6.7) and that of lung cancer was 5.7 mm (S. D. 3.5). The percentage of the mean length of spicules to the longest diameter of tuberculoma was 63.6% and that of lung cancer was 13.7%. The percentage of the mean length of spicules to the shortest diameter of tuberculoma was 90.4% and that of lung cancer w~s 18.3%. CONCLUSION: It is hard to differentiate lung cancer from tuberculoma on the basis of the spiculation being present or not, but we suggest that the longer spiculation be more highly suggestive of tuberculoma rather than lung cancer. The length of spiculation may help us differentiate lung cancer from tuberculoma.
