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.

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.

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.

PURPOSE: Diffuse panbronchiolitis(DPB) is a chronic inflammatory airway disease of unknown causes mainly affecting the respiratory bronchioles and the more proximal bronchi. Findings on chest radiographs and high-resolution CT(HRCT) are well known and Akira classified HRCT findings of DPB into four types. Purpose of this study is to evaluate the relationship between findings of HRCT and PFT. METHODS AND MATERIALS: We retrospectively analyzed the chest radiographs and HRCT images of eleven patients with DPB and compared CT classification with pulmonary function test. RESULTS: Chest radiographs usually showed small nodular opacities throughout the both middle and lower lungs. The HRCT findings of DPB were centrilobularly distributed small nodular densities, branching linear densities contiguous with small round densities, dilated and thickened peripheral and central airways including bronchioles. More than one CT type by Akira's classification, usually two or three types, were found in nine patients. There was good correlation between CT types and FEV1%(p<0.05), CT types and FEV1/FVC (p<0.05) respectively. CONCLUSION: HRCT seems to be more useful for diagnosis and disease progression of DPB as compared with the chest radiographs or clinical stage such as pulmonary function test.

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.
