BACKGROUND: The concentration of the blood including ACTH, catecholamine, serum prolactine, cortisol is increased due to responding on stress by carrying out endotracheal intubation upon the mutiple trauma patients who were taken to the emergency room. Diazepam is a kind of benzodiazepine pharmacon and common pharmacon used for stability of the patients, relief and pretreatment as a booster for the relaxation of skeletal muscle. This research aims to know how effectively medication of diazepam before endotracheal intubation helps to constrain the reaction on the part of cardiovascular system due to laryngoscopy and endotracheal intubation, and makes concentration of catecholamine in blood changed. METHODS: The subjects are consisted of the patient asked for endotracheal intubation instantly, suffering from caput trauma (GCS 8.0) among the multiple trauma patient, more than 20-year-old who were taken to the emergency room in Chosun university hospital from October 1, 1995 to September 30, 1996. They were decided into 2 classes, 30 people each class, and one (group I ) was carried out endotracheal intubation without injecting diazepam,0.3 mg/kg, and the other (group II) was done with the endotracheal intubation by injecting diazepam, 0.3mg/kg. Group I and group II were measured blood pressure and heart rate before intubation and at 1, 3, 5, 7 minute after endotracheal intubation, sampled arterial blood from femoral artery, and then compared and analyzed. All of the data were recorded by mean, standard deviation, and percentage and repeated measures ANOVA test was used for the statistical test and the data was regarded as statistically significant when p value is below 0.05. RESULTS: 1) They were no significant differences statistically between 2 groups in the distribution of the age, weight, sex of the patients. 2) The changes in the systolic blood pressure had no statistical significance in the comparison between group I and group II, but diastolic blood pressure and the change of heart rate had statistical significance because p value was shown below 0.05. 3) Norepinephrine of blood was significantly lower in group II than group I. 4) Epinephrine of blood was significantly lower in group II than group I. CONCLUSION: It was shown that medication of diazepam before endotracheal intubation made stability of the patients and it changed significantly the reaction on the part of cardiovascular system from stress caused by laryngoscopy and endotracheal intubation. So it will be a good thing to inject diazepam for pretreatment to bring relief of the patients and cardiovascular stability before endotracheal intubation.

The serous papillary cystadenoma of low malignant potential in the paratesticular tissue is a tumor characterized by its resemblance to ovarian serous papillary tumor of low malignant potential. Several possible origins have been proposed but it is thought to originate from the Mullerian-type epithelium just like ovarian serous tumor of low grade malignancy. Because of the rarity of this tumor, the natural history and treatment have not been established. Herein we report on a serous papillary cystadenoma arising in the paratesticular tissue of a 12 year old . To our knowledge, this is the first reported case in the Korean literature. The size of this cystic tumor in this patient was 0.9x0.9x0.8 cm and had a sponge-like cut surface. The papillary structure was lined by both ciliated and nonciliated secretory cells, the same cellular structure as the salpinx. Areas with just a few mitoses and stratification of epithelial cells were noted, but invasion into the paratesticular tissue was absent, suggesting borderline malignancy. He is doing well after 5 months follow up. Prognosis of this scrotal tumor is thought to be better than the ovarian tumor of similar histology due to a better possibility of early detection.

BACKGROUND: A novel technique for the repair of tears of the upper subscapularis tendon—intraarticular knotless fixation—has been introduced recently. The purpose of this study was to evaluate the clinical and structural outcomes of arthroscopic intraarticular knotless fixation for the treatment of upper subscapularis tendon tears. METHODS: We retrospectively analyzed the clinical and radiological outcomes of 27 patients who underwent arthroscopic intraarticular knotless fixation for upper subscapularis tendon tears. Finally, a total of 10 patients who could participate in at least a 6 month follow-up of magnetic resonance imaging evaluation and in a least 1-year follow-up on an outpatient basis were enrolled in our study. The mean age at the time of operation was 60.7 years, and the mean duration of follow-up was 14.7 months. Two patients had concomitant tears of the supraspinatus tendon and 8 patients had concomitant tears of the supraspinatus and the infraspinatus tendons. RESULTS: The clinical and radiological outcomes improved after the patients had undertaken arthroscopic intraarticular knotless fixation. The mean visual analogue scale score for pain during motion improved from 6.7 preoperatively to 1.4 at the final follow-up (p<0.001). The mean Constant score improved from 59.3 preoperatively to 79.6 at the final follow-up, and the mean the University of California at Los Angeles score, from 21.7 to 30.2, respectively (p<0.001 and p<0.001). The upper subscapularis tendon tear was healed in every patient except one (90%), for the patient had suffered from a postoperative trauma that resulted in a retear. CONCLUSIONS: We found that arthroscopic intraarticular knotless fixation gives good clinical and structural outcomes for the repair of upper subscapularis tendon tears. Arthroscopic intraarticular knotless fixation provided such a reliable and efficient restoration of the subscapularis tendon footprint that we anticipate it will become a widely-used procedure for upper subscapularis tendon tears.

BACKGROUND: The purpose of this study was to investigate the difference between two nailing approaches of intramedullary screw fixation, the retrograde nailing versus the anterograde nailing, on the radiological and clinical outcomes in patients with clavicle shaft fractures. METHODS: From April 2002 to August 2014, we enrolled a total of 22 patients with clavicle shaft fractures to participate in this study. Twelve patients received retrograde intramedullary nailing and 10 received anterograde nailing. The average duration of follow-up was 12 months. In all the patients, we took follow-up radiographs of the anteroposterior and the axial views to assess the postoperative radiological outcomes. We measured the visual analogue scale (VAS) score, American Shoulder and Elbow Surgeons (ASES) score, and the range of motion (ROM). RESULTS: Clinically, we did not find a statistically significant difference in the retrograde group and the anterograde group in terms of the duration to bone union, the VAS score the ASES score and the ROMs. Radiologically, we found that the difference in the clavicle shortening of the affected arm and the unaffected arm did not show a statistically significant difference at the immediate postoperative assessment. we found that the difference in the clavicle shortening of the affected arm between the immediate postoperative and the final follow-up value did not show a statistically significant difference. CONCLUSIONS: We found that both the retrograde nailing and the anterograde nailing gave a favorable outcome for clavicle shaft fractures. Although we saw evidence of clavicle shortening after intramedullary screw fixation, this was not a factor that influenced clinical outcome.

We have experienced an unusual case of hemorrhagic renal cyst in the rt. kidney at 58 years old woman. The Rt. kidney was enlarged, and showed a few subcapsular ischemic areas The color of kidney was dark brown. As the cyst at lower pole of rt. kidney was dissected, hemorrhagic fluid visualized in the cystic cavity. The final pathologic finding was renal cyst associated with malignant change and renal cell carcinoma at another renal parenchyma. Herein, hemorrhagic renal cyst, a rare clinical entity, was reported with review of literatures.

A case of calcifying synovial sarcoma, occuring in the deep muscle fascia of the left thigh is reported. The presence of extensive calcification in synovial sarcoma is a favorable sign for prognosis. The patient was a 31-year-old female. The tumor mass had been present for 3 years, accompanying local tenderness. X-ray revealed a soft tissue tumor with central calcification, which was located between the adductor magnus and brevis of the left thigh. The tumor size was 7 x 5.5 cm. There was no connection with the knee joint or the femur. Grossly, the tumor was a relatively well circumscribed hard tumor with massive calcification. Microscopically, the tumor was composed of predominantly spindle cells with accompanying hyalinization, numerous spherical concretions and ossification. The epithelial component was not clearly noted. Mitotic figures were rarely noted in the densely cellular area. Immunohistochemical staining for EMA, S-100, vimentin, and carcinoembryonic antigen was negative while vimentin and cytokeratin were weakly and focally positive. EM study revealed multiple desmosome-like calcification intercellular junctions with a slit-like lumen and an incomplete basal lamina, which suggest that tumor show these cells were undergoing epithelia] differentiation. Above evidence suggest that this tumor is a synovial sarcoma associated with a large area of calcification, a so called calcifying synovial sarcoma. No recurrence was noted in one and half years of follow up.

Chitin and chitosan, polysaccharides made up of polymeric N-acetly glucosamine and D-glucosamine, are widely found in nature, forming the skeletons of crustaceans and insects, as well as the components of bacteria cell walls. Chitin and chitosan have been known to have many useful biological properties such as biocompatibility, biodegradability, antimicrobial activity, and wound healing. There properties have been known to be different depending on the degree of deacetylation of chitin, but it has not yet been fully evaluated. The purpose of this study was to evaluate the wound healing effect by the degree of deacetylation. Full-thickness skin incision was made on the backs of Sprague-Dawley rats. Three concentrations of powder, comprising 90% chitin, 50% chitin and 10% chitin, were separately embedded in the wounds of 3 rat groups. The wound-breaking strength and the collagen-hydroxyproline content of the skin at the wound sites were measured and histological examination was performed at postoperative 3, 7, and 10 days. The 50% chitin group had the highest tensile strenght of all groups. But the 50% chitin and 90% chitin groups had the lowest collagen hydroxyproline levels among all groups. The wounds treated with 50% chitin powder were completely reepithelialized and granulation tissue in the wound was observed 7 days after initial wounding. The arrangement of collagen fibers in the skin was ordered and similar to normal skin The 50% chitin powder is considered to be the most efficient wound healing accelerator among different concentrations of chitin powder.

Many investigators have reported that collagen gel contraction reflects the mechanism of wound contraction. In 1995, Tsai et al. reported that hypertrophic scar-derived fibroblasts in a connective tissue model possessed the greatest contraction potency when compared with those of normal skin and normal oral mucosa-derived CTMs. In this study, we studied the effect of collagen gel contraction by growth factors such as epidermal growth factor, platelet-derived growth factor, transforming growth factor-bata1, and transforming growth factor-bata3, Skin fibroblasts used in this study were obtained from the explant of rat skin culture. Fibroblasts were cultured in Dulbecco's modified Eagle's medium containing 10% fetal bovine serum. Growth factors were added per FPCL in the desired concentrations and we measured the collagen gel diameters in growth factor-treated FPCL on day 1,2,3, and 4 respectively after starting incubation. We examined the effects of EGF, PDGF, TGF-bata1, TGF-bata3 and the effects of combinations of TGF-bata1 + EGF, TGF-bata1 + PDGF, and TGF-bata1 + TGF-bata3 to contract a collagen gel. EGF has little influence on collagen gel contraction. TGF-bata1 and TGF-bata3 increase the collagen contraction. TGF-bata1 enhanced the contractility of collagen gel according to the concentrations. While TGF-bata3 alone had stimulatory contraction effects at low dose, high doses of TGF-bata3 decreased the potency of collagen gel contraction. A combination of TGF-bata1 and EGF minimally decrease TGF-bata1 activity. A combination of TGF-bata1and PDGF had an effect similar to TGF-bata1 activity. A combination of TGF-bata1 and TGF-bata3 decreased TGF-bata1 activity. According to reports that FPCL contraction is equivalent to the process of wound contraction, growth factors which enhance gel contraction may be related to wound contraction and wound healing. TGF-bata1 is reported to enhance scar formation in fetal wound. EGF accelerates wound healing and inhibits the promotion of hypertrophic scar formation. Compared to the effect of collagen gel contraction in this study, the combination of TGF-bata1 and TGF-bata3 that inhibited the promotion of collagen gel contraction are thought to diminish the formation of scar tissue. As well, EGF that has not enhanced collagen gel contraction is thought to diminish the production of scar tissue. We will study the interactive effects of TGF-bata3, EGF and TGF-bata1 on the contraction of collagen gels in the future.
