BACKGROUND: Many studies reported that endothelium-dependent vasodilator response is impaired in patients with congestive heart failure. But the opposite results also were reported. The aim of this study was to determine the presence of endothelial dysfunction and its characteristics. METHODS AND MATERIALS: Forearm blood flow was measured in 12 patients with congestvie heart failure (7 males and 5 females, mean age 53+/-11 years old) and 10 normal control subjects (5 males and 5 females, mean age 41+/-10 years old) using strain-gauge plethysmography. The endothelium-dependent vasodilators were acetylcholine (7.5, 15, and 30 microgram/min), which uses a pertussis toxin-sensitive signal transduction pathway, and bradykinin (100, 200, and 400 ng/min), which uses a pertussis toxin-insensitive signal transduction pathway to activate nitric oxide production. Sodium nitroprusside (0.8, 1.6, and 3.2 microgram/min) was used as an endothelium-independent vasodilator. All drugs were infused into the brachial artery with random order. RESULTS: The basal forearm blood flow was similar between both groups. The maximum flow in response to acetylcholine, bradykinin, and sodium nitroprusside was also similar in two groups. CONCLUSIONS: Patients with congestive heart failure showed normal endothelium-dependent vasodilator responses to both acetylcholine and to bradykinin. This finding indicates that the endothelial vasodilator function is normal in the patients with heart failure.

Breast cancer is the second leading cause of cancer death in women. Unfortunately, the frequency of breast cancer and mastectomy are increasing in Korea. The purpose of the study is to analyze the results of breast reconstruction using free transverse rectus abdominis myocutaneous(TRAM) flap and to suggest the operative technique for more satisfactory results. 19 patients underwent immediate breast reconstruction from 1990 to 1998, and we experienced 2 cases of bilateral immediate reconstruction of breasts following mastectomy. We have performed the free TRAM flaps based on the deep inferior epigastric vessels using microvascular technique. TRAM flap included very small portion of rectus sheath and muscle-so called muscle sparing technique. So it reduced markedly donor site morbidity. The postoperative course of these cases was uneventful with minor complication. The free TRAM flap was an excellent method of immediate breast reconstruction using autogenous tissue and provided satisfactory outcome. The goals of the immediate breast reconstruction after mastectomy are to restore body image, to achieve near normal shape of breast, and to reduce the complications. This paper represents our experience of immediate breast reconstruction using free TRAM flap, and technical options to get more satisfactory result and reduce the complications. We think this method could be regarded as the first choice for immediate breast reconstruction.

Microsurgical reconstruction is necessary for children to correct severe trauma and congenital or acuqired deformity. The aim of this study was to evaluate whether or not microsurgical reconstruction is a safe and reliable operation in children and to analyze the differences of microsurgical reconstruction in children compared to adults. The study included 12 children who underwent 13 microsurgical reconstructions among a total of 251 cases of microsurgical reconstruction from May, 1986 to August, 1998. Their ages ranged from 24 months to 14 years and 8 months. There were 7 males and 6 females. The involved sites were 9 legs, 3 hands and 1 face. The causes of microsurgical reconstruction were 9 traumas, 2 congenital anomalies, 1 acquired deformity and 1 cancer. The applied flaps were 4 scapular flaps, 2 rectus abdominis muscle flaps, 1 de-epithelized groin flap, 1 lateral arm flap, 1 forearm tendocutaneous flap, 1 forearm tendocutaneous flap, 1 latissimus dorsi muscle flap, 1 fibula flap, 1 second toe transfer, and 1 wrap-around flap. All patients have had normal growth of the donor and recipient sites without specific complications during an average 2 years follow-up. We concluded that microvascular reconstruction is a very useful and reliable procedure in children if it is performed in consideration of each child's specific characteristics and conditions.

There is room for debate in appropriate diagnosis and treatment due to physiological and anatomical differences in pediatric facial bone fractures from that of adult's. The objectives of this article is to analyze for our clinical cases and to suggest the appropriate management of facial bone fracture in children. The study included 56 children who had treatment for the craniofacial fractures form March, 1990 to February, 1998. Their ages ranged from 3 to 15. There were 38 males and 18 females. Physical examination, simple x-rays, ultrasonograms and routine CT scans were used for diagnosis. Materials were classified into 28 nasal bone fractures, 4 nasoethmoidal fractures, 6 orbital fractures, 8 mandible fractures, and 10 zygoma fractures. Patients were treated with conservative treatment in 9 cases, with closed reduction in 28 cases and open reduction only, and 14 patients with open reduction and internal fixation using microplates and screws. 3 patients needed autogenous calvarial bone graft. Plates and screws were removed in postoperative 3-6 months. All patients had successful union of fractured bones without no specific complications, and normal bony growths were noticed during the 7 years follow up. We conclude that surgeons should be careful in diagnosis and management for the pediatric facial fracture due to anatomical variations and differences in fracture aspects. First, it is mandatory for surgeous to get accurate diagnosis and identify children's fracture and displacement through routine CT check up along with physical examination. Second, it is important to perform the minimally invasive technique or conservative treatment for the children with mild displacement so that it reduces the incidence of growth retardation which may be caused by extensive operation. However, application of rigid fixation is necessary in case of extensive bony displacement or bony defects because of poor coorporation in postoperative care. Third, plates and screws which were used for the internal fixation should be removed at 3-6 months after the surgery. Fourth, if bone graft is needed, it is better to use autogenous graft than allogeneous graft. Fifth, care for dentition and follow up for growth are necessary for growing children.
