From 1981 to 1993, one hundred and thirty eight patients had been treated by free flap or island flap, for the tissue defects of the extremities. Among these 138 patients, vascularized bone graft was 29 cases, soft tissue free flap 40, replantation 22, local island flap 45, and lymphovenous shunt 2. Average age at the time of operation was 27 years(1-66 years), and men were 110, women 28. Average duration of follow-up was 2 years and 8 months(4 months-11 years and 8 months). Twenty nine cases of vascularized bone graft was consisted of fibular graft in 15 patients, ilium 8, joint transplantation 4, thumb reconstruction using big toe 1, and rib 1. Four of them were failed. Among 40 patients of soft tissue free flap, latissimus dorsi flap was 12 cases, dorsalis pedis flap 11, scapular flap 8, wraparound procedure 7 and gracilis flap 2. Seven of them were failed. The levels of replantations were both lower extremities in one patient, leg 1, arm 2, distal forearm 2, and finger(s) 16. In six patients, replantation was nor successful. Among 45 patients of local island flap, lateral supramalleolar island flap was performed in 8 patients, dorsalis pedis flap 2, Chinese flap 10, reverse ulnar artery flap 4, reverse posterior interosseous artery flap 3, neurovascular island flaps for fingers 14, and others 4. Two of them were failed. Two cases of lymphovenous shunt for the treatment of lymphedema were successful. As a whole, 119 cases were successful(86%) among 138 cases including local island flap 45 cases.

Cardiopulmonary bypass in children is associated with capillary leak, which results in an increase in total body water after open heart surgery. The purpose of these studies was to assess the cardiopulmonary effects of modified ultrafiltration after pediatric open heart surgery. Study A: Twenty-six consecutive children aged 0.1~10 years(median 7 months) underwent cardiac operation incorporating modified ultrafiltration. After completion of cardiopulmonary bypass, modified ultrafiltration was commenced at the flow rate of 100~150l/min for 3~14 min. After modified ultrafiltration, elevation of hematocrit(28.3%+/-3.6% vs. 33.8%+/-4.0%, p<0.001), increased systolic blood pressure(66.7+/-11.2mmHg vs. 76.2+/-11.8mmHg, p<0.02), and decreased central venous pressure(7.8+/-3.7mmHg vs. 6.9+/-2.9mmHg, p<0.001) were observed. Study B: Twenty-six children who underwent cardiac operation with the diagnosis of VSD under 2 years were assigned to control(n=14) or modified ultrafiltration(n=12). Peak inspiratory pressure checked immediately after operation was significantly lower in modified ultrafiltration group than in control group(20.0+/-2.4 cmH2O vs. 22.4+/-2.3cmH2O, p< 0.03). Modified ultrafiltration after cardiopulmonary bypass in children improves early hemo- dynamics and pulmonary mechanics, and represents an excellent option for perioperative management of accumulation of fluid in the tissues. We will continually employ the modified ultrafiltration technique in pediatric cardiac operations.

DA-8159, a selective inhibitor of phosphodiesterase type 5, was developed as a new drug for erectile dysfunction. The effect of DA-8159 on the electroretinogram (ERG) and the retinal histopathology were evaluated in rabbits. The ERG was performed prior to, and 1 and 5 hr after DA-8159 (5 to 30 mg/kg) administration. The plasma concentration of DA-8159 was determined at each time point, and retinal microscopic examination was also performed. There was no statistically significant ERG change at any dose or at any time. Though the 30 Hz flicker showed a prolongation of the implicit time at 5 hr after the administration of either DA-8159 15 mg or 30 mg/kg (p<0.05), but concurrent amplitude decreases were not statistically significant. At a dose of 5 mg/kg, no test drug was detected in the blood after either 1 or 5 hr. At either 15 mg/kg or 30 mg/kg, there was a dose-dependent increase in the blood concentration after 1 hr of drug administration, which decreased with time. In light and electron microscopic examinations of the retina, there was no remarkable change at any dose. These results suggest DA-8159 has a low risk potential to the retina, but further evaluation on the visual functions in human is needed.

A number of authors have called attention to the difficulty encountered in diagnosing tumors near the foramen magnum and have formulated symptom complexes in an effort to facilitate early recognition of these lesions. Emphasis has been placed on their bizarre symptoms and on their resemblance to the clinical picture associated with some degenerative diseases of the central nervous system, ruptured cervical disc and cervical spondylosis. Fortunately, it has been known that most of tumors around the foramen magnum are benign, extramedullary and amenable to cure by surgical excision and with minimal morbidity and mortality, provided they are diagnosed early. Recently we experienced a rare case of glioblastoma multiforme at the cervico-medullary junction. A 28-year-old Korean man was admitted to the Dept. of Neurosurgery on May 27, 1974, with 5 months history of cervical and suboccipital pain, and progressive visual disturbance. He had sustained hyperextension injury to his neck 8 months ago, and subsequently developed mild suboccipital and cervical pain which subsided easily with some analgesice. Three months later, he noticed paresthesia and tingling sensation in his upper limbs and anterior chest, especially when he turned his neck to either side. He also had pain in suboccipital region radiating to his both shoulders. Seven months later, he developed sudden paraperesis, poor vision and incoordination with severe suboccipital headache and vomiting. On admission, neurological examination disclosed clear consciousness, bilateral papilledema and abducens nerve palsy and markedly decreased vision. There were clumsiness of movement of both legs, hypesthesia in the face, decreased perception of vibration and position sense below the neck and increased deep tendon reflexes. Fine coordination movements in the upper limbs were disturbed and horizontal hystagmus was also present. Simple skull films showed destruction of the dorsum sellae and the posterior clinoid process, suggesting increased intracranial pressure. Cervical spine films were interpreted as normal. Right carotid angiograms demonstrated marked hydrocephalic patterns, and right vertebral angiograms demonstrated posterior displacement of the tip of the basilar artery and of the choroidal point. Conray ventriculogram showed a sharp filling defect at the level of lateral recess of the fourth ventricle. Suboccipital craniectomy and bilateral laminectomy of the first two cervical vertebrae were performed, disclosing a nodular, meaty, firm mass with some necrosis. The tumor was located posterolateral to the medulla and the spinal cord from the obex to the C2, compressing them and displacing the right cerebellar tonsil upward and laterally. The tumor was removed partially and Torkildsen's shunt was performed. Post-operatively he died suddenly at the end of the second week without any remarkable improvement in symptoms and signs. Pathological report was a glioblastoma multiforme. At autopsy, the tumor was originated from the cervicomedullary junction, extending posteriorly from the obex to the C2 and anteriorly along the brain stem up to the perichiasmatic region.

Although many reseraches have been persued to detect the molecular tumor marker to define the cancer, ideal tumor marker which speak for the characteristics of malignancy and has high sensitivity and specificity is not known. One of the characteristics of the malignant cells is indefinite proliferative potential, in other word, immortality. The expression of telomerase and stabilization of telomeres are concomitant with the attainment of immortality in tumor cells; thus the measurement of telomerase activity in clinically obtained tumor samples may provide important information which would be useful as a diagnostic marker to detect immortal cancer cells. Telomerase activity was analyzed in 12 non-small cell lung cancer cell lines and 41 primary non-small cell lung cancers with the use of a PCR-based assay. All the cell lines and the majority of tumors displayed telomerase activity, but telomerase was not detectable in most of the corresponding pathologically-normal tissues. Telomere length was not correlated with telomerase activity. The present study indicate that measurement of telomerase activity may be useful as a molecular tumor marker in non-small cell lung cancer.

BACKGROUND: An increase in total body water and the systemic inflammatory response occurs during cardiopulmonary bypass (CPB) which has resulted in the release of inflammatory mediators, including tumor necrosis factor-alpha (TNFalpha), interleukin-1beta, interleukin-6,and interleukin-8. These substances were suggested to be responsible for postoperative organ dysfunction and morbidity. Conventional ultrafiltration (cUF) and modified ultrafiltration (mUF) were used in cardiac operations to reduce volume overload and total body water. The purpose of this study was to estimate the value of these techniques in removing inflammatory mediators during CPB. METHODS: Serial plasma samples were taken before CPB,after 1 hour of CPB, just before cUF, after cUF, after mUF and 24 hrs after bypass. Cytokines were detected using highly specific double-ligand enzyme-linked immunosorbent assays. The data were analyzed using the repeated measurement ANOVA. RESULTS: TNFalpha, interleukin-1beta, interleukin-6, and interleukin-8 were increased during CPB and peaked just before cUF. After cUF, all four cytokines had been significantly decreased. After mUF,interleukin-6 and interleukin-8 had significantly been decreased, but TNFalpha and interleukin-1beta did not change significantly. After 24 hours of CPB , TNFalpha and interleukin-8 returned to preCPB values, but interleukin-1beta and interleukin-6 did not. CONCLUSIONS: We conclude that ultrafiltration has the potential to remove cytokines from the circulation. The ultrafiltration technique may be a useful technique in the management of patients undergoing bypass, particularly in patients at high risk of accumulating fluids and inflammatory reactions.

PURPOSE: The objective of this study was to examine the psychological features and coping strategies of patients with chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). MATERIALS AND METHODS: The participants consisted of 55 military personnel suffering from CP/CPPS and 58 military personnel without CP/CPPS symptoms working at the Military Capital Hospital. The National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) was used to assess CP/CPPS symptoms. The Responses to Hospital Anxiety and Depression (HAD) scale, Social Readjustment Rating Scale, and Global Assessment of Recent Stress (GARS) scale were compared between the two groups. The Weisman Coping Strategy Scale was used to assess coping ability with CP/CPPS. RESULTS: The NIH-CPSI score of the CP/CPPS group was significantly higher than that of the control group for all domains including pain, urinary symptoms, quality of life, and summed score. The Anxiety and Depression domain of the HAD showed significant differences between the two groups. There were no significant differences in the Social Readjustment Rating Scale between the two groups, but the sum of the GARS score was higher in the CP/CPPS group than in the control group. These were correlated with the pain, quality of life, and sum domains of the NIH-CPSI. The Weisman Coping Strategy Scale showed that intellectualization, redefinition, and flexibility were higher in frequency in descending order, and that fatalism, externalization, and self-pity were lower in frequency. CONCLUSIONS: The CP/CPPS patients had depression, anxiety, and higher perception of stress. In particular, these were closely related to the pain and quality of life of the patients.

BACKGROUND: Skin grafting is a relatively simple and thus widely used procedure. However, the elastic and structural quality of grafted skin is poor. Recently, various dermal substitutes have been developed to overcome this disadvantage of split-thickness skin grafts. The present study aims to determine the feasibility of RapiGraft as a new dermal substitute. METHODS: This prospective study included 20 patients with partial- or full-thickness skin defects; the patients were enrolled between January 2013 and March 2014. After skin defect debridement, the wound was divided into two parts by an imaginary line. Split-thickness skin grafting alone was performed on one side (group A), and RapiGraft and split-thickness skin grafting were used on the other side (group B). All patients were evaluated using photographs and self-questionnaires. The Manchester scar scale (MSS), a chromameter, and a durometer were used for the scar evaluation. The average follow-up period was 6 months. RESULTS: The skin graft take rates were 93% in group A and 89% in group B, a non-significant difference (P=0.082). Statistically, group B had significantly lower MSS, vascularity, and pigmentation results than group A (P<0.05 for all). However, the groups did not differ significantly in pliability (P=0.155). CONCLUSIONS: The present study indicates that a simultaneous application of RapiGraft and a split-thickness skin graft is safe and yields improved results. Therefore, we conclude that the use of RapiGraft along with skin grafting will be beneficial for patients requiring reconstructive surgery.
