Dynamic cardiomyoplasty is a recently introduced surgical method to improve myocardial performance. It consists of a placement of a skeletal muscle flap around the heart and stimulation of the flap in synchrony with ventricular contraction. We experienced a case of cardiomyoplasty in a 25 year old male patient with congestive heart failure. Anesthesia was induced and maintained with fentanyl, midazolam and isoflurane. The operation was performed for 8hrs without cardiopulmonary bypass and the patient was transferred to the intensive care unit. He was mechanically ventilated electively overnight and extubation was done 18hrs postoperatively. The patient was discharged home on the 40days after operation and improved in exercise tolerance. We report the anesthetic management and hemodynamic changes in a patient who underwent dynamic cardiomyoplasty.

Ischemic stroke is a serious neurological complication of infective endocarditis. Intravenous tissue
plasminogen activator (t-PA), which has only been approved for treatment of hyperacute stroke, has
been excluded as an ischemic stroke treatment due to infective endocarditis according to current expert
consensus guidelines. Here, we describe a case of a hyperacute stroke patient treated with intravenous
t-PA, who was later diagnosed with infective endocarditis.

A global increase in the incidence of tuberculosis has prompted the need for earlier diagnosis,
treatment, and isolation of the disease. In tuberculosis, concomitant tuberculous meningitis and vascular
complications such as intracranial aneurysms and subarachnoid hemorrhage are very rare. Because
of the poor prognosis of tuberculous meningitis as well as intracranial aneurysm and subarachnoid
hemorrhage, early diagnosis and management are crucial. We present the case of a 76-year-old woman
who had two intracranial aneurysms complicated by subarachnoid hemorrhage, who had concomitant
tuberculous meningitis. She remained well with medical management.

Jehovah,s Witnesses who require operation represent a challenge to the physician because of the patient,s refusal to accept blood transfusion. An orthotopic heart transplantation was succesfully performed in a 40-year old Jehovah,s Witness without use of any blood product. During the operation, cell saver was used for shed blood and aprotinin was administered intravenously. The use of blood conserving methods, meticulous operative technique and brisk postoperative diuresis has added to the efficacy of heart transplantation in this patient. Total postoperative drainage was 860 ml and the lowest hemoglobin level was 11.8 g%. The patient recovered uneventfully and discharged on the 60th postoperative day.

BACKGROUND: Serious pulmonary complications after lung surgery increase morbidity and mortality in perioperative period. Ketamine hydrochloride produces strong analgesic effect in spite of the psychomimetic effects. Intravenous anesthesia with ketamine was performed in lung surgery of patients with decreased pulmonary function and compared with inhalation anesthesia with enflurane. METHODS: Sixty patients, scheduled for elective lung surgery, were randomly assigned to two groups. Patients received either enflurane (Group 1, n=30) or ketamine (Group 2, n=30) as main anesthetic drug. Blood pressure and heart rate were compared in preinduction, postinduction, postintubation, postincision, intraoperative period (30 minutes, 60 minutes) and recovery room between groups, and in each group. Arterial blood gas analysis was compared in preoperative period, intraoperative period and recovery room between groups. Postoperative psychological complications evaluated in group 2. RESULTS: Blood pressure and heart rate were significantly different in postinduction, postintubation and recovery room between groups. PaO2 in group 2 was higher than in group 1 during intraoperative period and recovery room. Postoperative psychological complications occured in 4 patients (13%) in group 2. CONCLUSIONS: Ketamine affords advantage over enflurane anesthesia in terms of PaO2 during intraoperative period and recovery room in lung surgery of patients with decreased pulmonary function.

Gardner's syndrome is a familial disease consisting of gastrointestinal adenomatous polyposis, osteomas of the mandible, skull, and long bones, and a variety of sol tissue lesions, including sebaceous cysts, fibromas, lipomas, and desmoid tumors. The colon is the most common site for polyposis, but the stomach, duodenum, small bowel, and periampullary area may also be involved. The diagnostic evaluation, malignant potential, and management is identical to that for familial adenomatous polyposis. The extracolonic manifestations of Gardner's syndrome are frequent and varied. Gardner's syndrome is inherited as autosomal dominant traits. Authors experienced one case that is a 32 year old female patient who had colonic and duodenal multiple polyposis, desmoid tumor in abdominal wall and right mesocolon and odontoma on mandible.

Proliferative scarring in the form of keloids and hypertrophic scars continues to be a clinical problem for some patients. The lack of an animal model for such scarring has been an obstacle to studying the biology and effective therapy of these entities. Consequently we created an accurate reproductive animal model to systematically study them. Human proliferative scars were explanted into flaps based on isolated vascular pedicles in congenitally rats. We compared the procollagen type III peptide levels of proliferative scar tissue before and after explanting. The procollagen type III peptide levels of explanted proliferative scar tissue remained increased as before explanting. Histological analysis of the explanted proliferative scar tissue revealed that all explants retained their original histotypic character even after 1 year. We could also retain the volume of implanted proliferative scar for 1 year and studied in vitro cellular proliferation. Fibroblast cultures from explanted scars demonstrated less aggressive growth characteristic than those from original surgical specimens. The advantages of this animal model are as follows: 1. The explants retain their histotypical character for a long period. 2. Placement of the explants outside the dorsum of a nude rat makes serial observation and measurement easier. 3. Agents under test can be injected into the explants through a catheter inserted into a single pedicle of island flap without the possibility of spreading systematically.

Although sacrococcygeal mass is rare and usually found in infants or children, adolescent or adult patients with protruding mass in sacrococcygeal region occasionally come to us simply for a cosmetic problem. In this situation, even though there is no definite neurological deficit, it should be evaluated whether or not the underlying bony pathology or dural defect exists. Few cases about the sacrococcygeal mass have been reported in adults. We reviewed our cases including preoperative evaluation methods and postoperative diagnosis. From March, 1993 to February, 1997, we experienced 6 adult patients with sacrococcygeal mass and no neurological abnormality. Preoperative evaluation were made by plain X-ray, myelogram, computed tomography(CT), and magnetic resonance imaging (MRI), as needed. Postoperative diagnoses were 2 meningoceles, 2 lipomyelomeningoceles, 1 desmoid tumor, and 1 teratoma. From our experiences, CT or MRI is essential to evaluate the sacrococcygeal mass preoperatively. These methods can visualize the precise anatomic location and extent of the mass, its relation to the spinal cord, and associated bony abnormalities. MRI is superior to CT, especially in defining the nature of the mass and involvement of the spinal cord. Conclusively, even a simple mass in the sacrococcygeal region in adults needs MRI or CT evaluation, and MRI is the most valuable method of evaluating the mass preoperatively and provides important information to establish a treatment plan.

To investigate the effects of prostaglandin E1(PGX1) in prevention of proliferative scar formation, we cultured fibroblasts of normal skin (NS), hypertrophic scar (HS) and keloid (KL) tissues obtained from patients. We have compared type I collagenase production of cultured fibroblasts from normal skin, hypertrophic scar, and keloid tissues under various concentrations of PGE1. Our results demonstrate that type I collagenase production was significantly increased after addition of PGE1 in HS and KL, but not NS. Type I collagenase production of HS and KL fibroblasts were increased similarly in 10M and 10M of PGE1 and maximally increased in the concentration of 10M. This promotive effects of PGE1 on the production of type I collagenase was larger in KL than in HS. These results also suggest that PGE1 may play the promotive effects on type I collagenase production in dose-dependent manner. PGE1 may have a role in the prevention of hypertrophic scar and keloid by enhancing the production of type I collagenase of HS and KL fibroblasts. The promotive effects of PGE1 on type I collagenase production was variable depending on its concentration, and its effects was maximum in certain optimal condition. The maximally effective concentration of PGE1 in the prevention of proliferative scar formation should be searched in further investigations for clinical use.
