The clinical applications of free have been extended tremendously in head and neck reconstruction. In a nine-year period, 92 microvascular free flaps were performed to repair the defects following major head and neck ablative surgery. Twenty-one transverse rectus abdominis myocutaneous flaps, 18 radial foream flaps, 15 latissimus dorsi muscle flaps, 12 jejunal flaps, 8 fibular osteocutaneous flaps, 6 rectus abdominis muscle flaps, 6 iliac osteomyocutaneous flaps, 2 groin fasciocutaneous flaps, 1 scapular fasciocutaneous flap, 1 parascapular osteocutaneous flap, 1 tensor fascia lata muscle flap and 1 serratus anterior muscle flap were used for reconstruction. Twenty-five maxillary defects including the orbit or skull base, 16 pharyngoesophageal defects, 15 intraoral defects, 15 mandibular defects, 13 scalp defects, 1 cervical region and 7 other facial region were covered with various free flaps. The overall success rate of the flaps was 95.6%. The complications included total flap loss (3 cases), partial flap loss (1 case), recurrence of primary tumors (15 cases), cerebrospinal fluid leakage (3 cases), fistula formation (3 cases) and infection (5 cases). Superficial temporal artery, facial artery, superior thyroidal artery, lingual artery, occipital artery, transverse cervical artery were commonly used recipient arteries and 7 cases of vein grafts were used if indicated. End to end anastomosis was performed in 84 cases and end to side anastomosis in 8 cases. The average follow-up period was 42 months, ranging from 6 months to 8 years. One patent died during postoperative intensive care due to sepsis and 19 patients died because of recurrence of tumors and underlying medical diseases during the follow-up period. Although free flaps may appear to be riskier than traditional forms of reconstruction, they offer the surgeon a greater spectrum of reconstructive options. Free flap reconstruction also improves the quality of life and minimizes the loss of function. Limitations of the use of free flaps result only from a lack of technical skills and specialized equipment.

Until recently, cranial base tumors or midfacial tumors were deemed unresectable due to an inability to accurately diagnose the extent of the involvement and to approach and excise the tumor safely. With refinements in CT and NMR scanning, as well as the development of craniofacial technique, reconstruction has become absolutely crucial in allowing successful resection of these tumors. Resection of these tumors may sometimes result in massive and complex extirpation defects that are not amendable to local tissue closure. In such cases, free tissue transfer was an effective alternative because it can provide a large amount of well-vascularized tissues arts reliable separation of the intracranial space from bacterial flora of the upper airway. Microvascular free tissue transfer was used in 15 patients at our center to reconstruct the cranial base and/or midfacial defects. Of these 12 were free rectus muscle flaps, 2 were free latissimus dorsi muscle flaps, 1 was a free scapular osteocutaneous flap and 1 was a free scapular fasciocutanegus flap. There were 2 cases of total flap loss. In those cases, revisions were performed using latissimus dorsi muscle free flap in one case and STSG in the other. One patient had a postoperative cerebrospinal fluid leak which was spontaneously resolved by conservative management. The large complex defects were successfully reconstructed by one-stage operation and the functional and esthetic results wee satisfactory with acceptable complication rates.

BACKGROUND: Intra-aortic balloon pump (IABP)is well known for its hemodynamic benefit but still has its own complications.Proper use of IABP is the best way t o obt ai n maximum benefit with low complication rate. MATERIALS AND METHOD: Twenty one(men 10,female 11) patients were included in this study among the 100 consecutive adult cardiac surgery patients in our hospital.Eighteen(85.7%)were ischemic heart disease patients.They all received IABP therapy due to postcardiotomy cardiogenic shock according to the well-known indications.Their preoperative conditions,intraoperative factors including hemodynamics, postoperative conditions and IABP-related complications were analyzed. RESULT: Nineteen patients(90.5%)were successfully weaned from IABP.There were 2 patients of operative death and the mortality rate was 9.5%.Duration of IABP use was 40.7+/-24.3 hours.There were 2 cases(9.5%)of IABP-related vascular complications that required surgical intervention. CONCLUSION: We concluded that IABP could be used effectively and safely for postcardiotomy cardiogenic shock patients with low complication rate.

OBJECTIVES: The authors have intended to know the drug interaction of fluoxetine and haloperidol when coadministering two drugs to the chronic schizophrenics by assessing the changes of positive, negative symptoms and extrapyramidal symptoms. METHOD: We selected 38 patients, the chronic schizophrenics with no physical problems. they are randomly assigned to placebo group and drug group. And then, placebo or fluoxetine 20mg were administered to the subjects of each group during 8 week period. We have assessed their psychopathology and extrapyramidal symptoms using positive and Negative Syndrome Scale(PANSS), Clinical Global Impression(CGI), Simpson-Angus Scale at o, 2, 4, 6, 8 week during the period. RESULTS: 38 patients have completed the study during 8 week. 1) PANSS, CGI : no significant difference between groups and no significant change according to the times. 2) Simpson-Angus Scale : no significant changes. CONCLUSION: When co-administering fluoxetine and haloperidol, there were no significant changes of psychopathology and extrapyramidal symptoms. There results suggest that it is safe to coadminister fluoxetine to schizophrenic with haloperidol treatment.

Spontaneous pneumothorax is a known, but relatively rare complication of pulmonary metastases of sarcoma. A 19-year-old man was presented with chest pain and dyspnea for three days and was diagnosed as left pneumothorax. After bleb resection, microscopic examination revealed metastatic osteosarcoma forming subpleural fistula and dystrophic calcification. Four years ago, he had had limb salvage operation and chemotherapy for osteosarcoma of left femur. After two and a half years he had a bleb resection for right pneumothorax without any evidence of metastasis. Six months later, he was found to have a 4x3cm sized lung mass in the right lower lobe. After lobectomy, he was diagnosed as pulmonary metastasis of osteosarcoma. Pneumothorax is the common complication of metastatic osteosarcoma to the lung and it may be presented before the pulmonary metastasis is clinically evident. It is important to recognize a pneumothorax of the patients with osteosarcoma as a possible sign of metastases.

BACKGROUND: Hepatitis C virus (HCV) causes a chronic infection, resulting in progressive liver damage. Recent studies have described the protective effect of the apolipoprotein E (ApoE) genotype on liver damage in cases of HCV infection. Their findings were explained by the influence of the ApoE genotype on HCV pathology, which seems to be integrally linked to the process of HCV uptake into hepatocytes. We investigated whether specific ApoE genotypes were associated with the different clinical aspects of HCV infection in patients with chronic HCV. METHODS: From the whole blood of 196 chronic HCV hepatitis patients, the ApoE genotypes were determined by an allele-specific polymerase chain reaction. Several markers, including liver enzymes, platelet counts and HCV viral loads, as well as the radiologic findings, were investigated. In order to estimate the treatment outcome, the sustained virologic response (SVR), early virologic response (EVR) and end-of-treatment response (ETR) were determined according to the HCV viral loads. RESULTS: Based on genotyping, 15.8% (n=31) of the patients had the ApoE E4 allele (E2/E4, E3/E4, E4/E4), while 84.2% (n=165) were missing the ApoE E4 allele (E2/E2, E2/E3, E3/E3). Several clinical results of the E4-positive group, including liver enzymes, albumin, platelet counts, HCV viral loads and hepatic coarseness were not significantly different from those of E4-negative group. There were no differences in the SVR, EVR and ETR between patients with the ApoE E4 allele and those without the ApoE E4 allele. CONCLUSION: There was no significant effect of the ApoE genotype on the clinical aspects of HCV infection and the anti-viral response, including SVR, EVR and ETR, in chronic HCV hepatitis patients.

One hundred patients with hyperventilation syndrome presenting to emergency department(ED) were studied. Those were diagnosed on clinical basis by emergency medical physician. The male to female ratio was 15 : 85. In monthly distribution, the numbers of patients were increased during the two months, June and July. The 41% of patients visited the emergency center from 9:00 p.m. to 3:00 a.m.. The most common predisposing factors were the domestic problems, especially those between husband and wife(37%). Presenting complaints were dyspnea(34), paresthesia(30), muscle spasm(24), dizziness(6) and palpitation(6 patients). The initial examination of the patients in the ED were as follows, systolic blood pressure(134+/-7.15mmHg), heart rate(87.67+/-14.34/minute), respiratory rate(22.21+/-3.34/minute) and body temperature(36.61+/-0.31 degrees C, n=98). Arterial blood gas analysis showed alkalemia(pH 7.51+/-0.09) and hypocapnia(PCO2 26.67+/-8.30mmHg). After emergency cares, including carbone dioxide re-breathing and antianxietics, most of the symptoms were disappeared. The mean duration of stay in ED was 3.27+/-0.23 hours. The most important considerations in diagnosis of hyperventilation syndrome was the patients's history and the effective management was carbon dioxide rebreathing for a few minutes and antianxietics.
