BACKGROUND: Endotracheal intubation is accomplished for safe airway establishment, anaesthesia and operation in operating room, intensive care unit and emergency room mostly. Therefore, it will be beneficial that we predict and provide against difficult airway. With this view, our study was planned and carried out. METHODS: For 251 patients with ASA physical status I or II undergoing general aneathesia, the correlation between their age, sex, height, weight, BMI (body mass index), Samsoon & Young classification and laryngoscopic grades by Cormack & Lehane was investigated. RESULTS: Laryngoscopic grades were correlated significantly with patients' age and Samsoon & Young classification. Endotracheal intubation succeeded all, but, 8 patients (3.2%) were difficultly intubated with cricoid cartilage compression and stylet-using. CONCLUSIONS: Before intubating the trachea, it is desirable that patient' age, Samsoon & Young classification and the extent of neck's movement are assessed.

Herein, polyorchidism possessing of more than the usual number of testicles, which was found in two patients, is reported. Both patients had three testes, and one presented with painful swelling of the right scrotum caused by torsion of the testis and the other revealed a non-palpable testis in the right hemiscrotum. Both patients were managed surgically with orchiopexy and an orchiectomy, respectively, followed by the insertion of an artificial testis.

Objective Little is known about the role of low oxygen concentration in the formation of the capsule of Cryptococ -cus neoformans .This study was to investigate the effect of hypoxic condition on the capsule size of Cryptococcus neoformans . Methods We cultured 39 Cryptococcus neoformans strains in liquid Sabouraud medium and then incubated them at the normoxic (21%) and hypoxic concentration (1%), respectively.After 72 hours of incubation, we observed the capsules formed at different ox-ygen conditions under the Olympus microscope and the measured their sizes using the Axiovision software . Results Of the total number of Cryptococcus neoformans strains , 30 showed larger capsules in the normoxic than in the hypoxic condition , 17 with statisti-cally significant differences in their diameters (P<0.05), while the other 9 strains exhibited just the opposite results , 4 with statisti-cally significant differences in their diameters ( P<0.05). Conclusion Hypoxia might inhibit the growth of the Cryptococcus neoformans capsule.However, further studies are needed on its correlation with the serum or gene types of the Cryptococcus neofor-mans strain.

In 1952, Zoon described eight cases of benign circumscribed chronic balanitis characterized by an extensive infiltration of plasma cells with no evidence of dysplasia of the overlying epidermis. Plasma cell balanitis can often be confused clinically with other conditions, such as erythroplasia of Queyrat, fixed drug eruptions, secondary syphilis, candidiasis and Reiters disease. We report a case of plasma cell balanitis in a 65-year-old man. He complained of a single, red, shiny and smooth patch involving the glans penis and adjacent prepuce. This patch was unresponsive to systemic and topical steroid treatment. Laboratory studies were negative or within the normal range. Histopathological findings showed a band-like mainly plasmacytic inflammatory infiltrate of the upper dermis. This patient was treated once daily with 2% fusidic acid cream topically for 5 weeks. The lesions resolved and no recurrence was observed during 2 years of follow-up.

STATEMENT OF PROBLEM: A number of studies about the nano-treated surfaces of implants have been conducting along with micro-treated surfaces of implants. PURPOSE: The purpose of this study was to get information for the clinical use of nano-treated surfaces compared with micro-treated surfaces by measuring removal torque and analyzing histological characteristics after the placement of various surface-treated implants on femurs of dogs. MATERIAL AND METHODS: Machined surface implants were used as a control group. 4 nano-treated surface implants and 3 micro-treated surface implants [resorbable blast media surface (RBM), sandblast and acid-etched surface (SAE), anodized RBM surface] were used as experimental groups. Removal torque values of implants were measured respectively and the histological analyses were conducted on both 4weeks and 8weeks after implant surgery. The surfaces of removed implants after measuring removal torque values were observed by scanning electron microscopy (SEM) at 8 weeks. RESULTS: 1. Removal torque values of the nano-treated groups were lower than those of micro-treated groups. 2. Removal torque values were similar in the anodized RBM surface groups. 3. On the histological views, there was much of bone formation at 8 weeks, but there was no difference between 4 and 8 weeks, and between the types of implant surfaces as well. CONCLUSION: It is suggested that implant topography is more effective in removal torque test than surface chemistry. To get better clinical result, further studies should be fulfilled on the combined effect of surface topography and chemistry for the implant surface treatments.

BACKGROUND: The implementation of intraoperative normovolemic hemodilution is a strategy used in an attempt to diminish the need for or obviate allogeneic transfusion and to avert the potential complications. The goal of this study was to evaluate the safety and efficacy of moderate intraoperative normovolemic hemodilution. METHODS: Fifteen patients scheduled for posterolateral spinal fusion underwent intraoperative normovolemic hemodilution with 10% pentastarch to a target hematocrit level of 25% (hemodilution group). All units of blood procured by hemodilution and additional allogeneic blood was transfused in the perioperative period to maintain the hematocrit level of>25%. We investigated the effect of hemodilution on whole blood coagulation as measured by the thromboelastography and, evaluated its efficacy of decreasing the need for allogeneic blood transfusion as compared to the nonhemodilution group, retrospectively. RESULTS: Hemodilution with pentastarch caused a decrease in response and coagulation time (p<0.01) but did not influence on the alpha angle and maximum amplitude on thromboelstogram. Amount of transfusion of allogeneic blood was 4.1 1.7 units for the hemodilution group and 5.0 1.5 units for the nonhemodilution group. Net red blood cell volume ""saved"" from hemodilution was about 120 ml. CONCLUSION: Moderate intraoperative normovolemic hemodilution with pentastarch does not affect the coagulability of whole blood. But its efficacy of decreasing the need for allogeneic blood transfusion is minimal.

A 65 year-old male patient presented with a large palpable mass beneath the areola of the right breast for 7 years. The resected breast tissue was almost totally replaced by a round large solid mass (9 6 cm) with a pink-gray to yellow firm, partly nodular cut surface. Microscopically, the tumor revealed the diagnostic biphasic cellular pattern of adenoid cystic carcinoma, which consisted of both cribriform pattern of myoepithelial cells and tubular pattern of epithelial cells. On immunohistochemistry, the tumor revealed immunoreactivities for alpha-smooth muscle actin and S-100 protein in the myoepithelial cells and for AE1/AE3 in the epithelial cells. Mitoses were scarce. Multifocal lymphatic permeation and foci of perineural invasion were also found. Underlying resection margins and overlying skin were invaded by the tumor. We diagnosed this tumor as grade II adenoid cystic carcinoma according to the system utilized for the salivary gland tumors.

PURPOSE: Four finite element models were constructed in the mandible having a single implant fixture connected to the first premolar-shaped superstructure, in order to evaluate how the shape of the fixture and the implant-abutment connection would influence the stress level of the supporting tissues, fixtures, and prosthethic components. MATERIAL AND METHODS: The superstructures were constructed using UCLA type abutment, ADA type III gold alloy was used to fabricate a crown and then connected to the fixture with an abutment screw. The models BRA, END, FRI, ITI were constructed from the mandible implanted with Branemark, Endopore, Frialit-2, I.T.I systems respectively. In each model, 150 N of vertical load was placed on the central pit of an occlusal plane and 150 N of 40.oblique load was placed on the buccal cusp. The displacement and stress distribution in the supporting tissues and the other components were analysed using a 2-dimensional finite element analysis. The maximum stress in each reference area was compared. RESULTS: 1. Under 40.oblique loading, the maximum stress was larger in the implant, superstructure and supporting tissue, compared to the stress pattern under vertical loading. 2. In the implant, prosthesis and supporting tissue, the maximum stress was smaller with the internal connection type (FRI) and the morse taper type (ITI) when compared to that of the external connection type (BRA and END). 3. In the superstructure and implant/abutment interface, the maximum stress was smaller with the internal connection type (FRI) and the morse taper type (ITI) when compared to that of the external connection type (BRA and END). 4. In the implant fixture, the maximum stress was smaller with the internal connection type (FRI) and the morse taper type (ITI) when compared to that of the external connection type (BRA and END). 5. The stress was more evenly distributed in the bone/implant interface through the FRI of trapezoidal step design. Especially Under 40.oblique loading, The maximum stress was smallest in the bone/implant interface. 6. In the implant and superstructure and supporting tissue, the maximum stress occured at the crown loading point through the ITI. CONCLUSION: The stress distribution of the supporting tissue was affected by shape of a fixture and implant-abutment connection. The magnitude of maximum stress was reduced with the internal connection type (FRI) and the morse taper type (ITI) in the implant, prosthesis and supporting tissue. Trapezoidal step design of FRI showed evenly distributed the stress at the bone/implant interface.

PURPOSE: Detrusor instability (DI) is a main cause of persistent voiding difficulty after TURP in patients with benign prostatic hyperplasia (BPH). So we retrospectively estimated the effect of TURP in BPH patients with DI. MATERIALS AND METHODS: Of the 81 patients who had undergone TURP due to prostatism, 35 patients with BPH were followed at 3 weeks and 6 months postoperatively (21 without DI cases vs. 14 with DI; 6 persistent DI, 7 resolved DI, 1 missing case at 3 weeks and 4 persistent DI, 7 resolved DI, 2 missing cases at 6 months). We compared each group using symptom score (IPSS) and urodynamic parameters. RESULTS: Each irritative and obstructive symptoms were significantly improved in both group (p<0.05). The maximal flow rate (from 12.2 to 25.4ml/sec), average flow rate (from 8.9 to 15.2ml/ sec), residual urine volume (from 135.9 to 39.1ml) in patients without DI and maximal bladder volume (from 150.0 to 203.7ml), maximal flow rate (from 12.5 to 18.6ml/sec), residual urine volume (from 65.7 to 26.0ml) in patients with DI were improved significantly (p<0.05) after TURP, but other parameters were not improved (p>0.05). There were no significant differences in all parameters between 3 weeks and 6 months postoperative period (p>0.05). The amplitude of improvement had no significant difference between two group. There were no significant differences in IPSS and urodynamic parameters between persistent and resolved DI group. CONCLUSION: We suggest that TURP is good therapeutic option even in BPH patients with DI at short term postoperative period, but attempt to predict which patients would have persistent DI following TURP was failed.
