Total anomalous pulmonary venous return(connection) is a congenital heart disease. Especially, the reports of the patients with double connections of all pulmonary veins were rare. An infant who underwent operation for total anomalous pulmonary venous return had double drainge of all pulmonary veins to both left vertical vein and anomalous descending vein. This second lesion was not diagnosed preoperatively, but in operative field. Operative treatments were performed by ligation of left vertical vein and central pulmonary vein-to-left atrium anastomosis without ligation of the descending anomalous vein. For these less common variants fo total anomalous pulmonary venous return,a more detailed and precise understanding of morphology can facilitate accurate surgical repair. And also, early detection of the disease is an another issue for a good prognosis.

Clear cell sarcoma (CCS), also called malignant melanoma of soft parts, is a rare malignant soft tissue tumor and is often associated with tendons or aponeuroses. Most of CCS involve extremities, especially lower extremities, but a tumor occurring in the trunk is rare. We report an extremely rare case of CCS originated in the upper thoracic back muscle. To our knowledge, this case is the second report of CCS of the back muscle.

A spinal synovial cyst is an uncommon lesion associated with degenerative spinal arthropathy. It can cause radicular symptoms and may masquerade clinically as other, more common entities. A 50-year-old female presented with an intraspinal synovial cyst at the L5-S1 level manifesting as lower back pain and right leg pain. The patient's clinical symptoms improved after surgical management. Intraspinal synovial cyst should be considered in the differential diagnosis of the patients presenting with acute radicular symptoms.

BACKGROUND: The chronic disease patients have various psychological problems during the treatment. Therefore, it is needed about understanding and support for chronic disease patients. The main purposes of this study are to identify the psychometric characteristics. METHODS: To evaluate the psychometric characteristics of chronic disease patients-liver cirrhosis, chronic pulmonary disease, etc. -a questionnaire(SCL-90-R) survey was performed toward 100 chronic disease patients in admission to 2 general hospital. 100 persons without any disease were investigated by the same questionnaire for comparison. The survey was performed from June to August 1996. RESULTS: The disease history among the patients, 31% of patients suffered from liver disease, 19% of patients suffered from chronic respiratory disease. 30% of patients reported that they were not expected a recovery from the disease. The patients have a significant higher score in the somatization, obsessive-compulsive, interpersonal sensitivity, depression, anxiety, hostility, phobic anxiety, paranoid ideation, psychoticism than normal control (p<0.05). Most of the psychometric characteristics were associated with expectancy of the recovery, education about the disease, number of admission, duration of admission and type of disease(p<0.05). CONCLUSIONS: The chronic disease patients showed higher score psychological symptoms in various characteristics than normal control. Therefore it will be needed that is an proper treatment and psychological support continuously.

Macrostomia is a relatively rare malformation. There have been many surgical methods for the correction of macrostomia. The old method, a simple straight line closure , did not include reconstruction of the orbicularis oris muscle. Postoperatively, a depressed scar and severe contraction on the cheek were found, especially with animation. As a result, many authors have known that reconstruction of the orbicularis oris muscle was very important to avoid a depressed scar for the correction of macrostomia. The tendency toward lateral displacement of the reconstructed commissure has been attributed to linear scar contraction, and Z-plasty is advocated to prevent this deformity. However, we found that the Z-plasty scar may be conspicuous when the patient smiles. So we performed reconstruction of the orbicularis oris muscle to avoid a depressed scar, and straight line closure to avoid a conspicuous scar. In order to prevent linear scar contracture due to straight line closure, we overcorrected the new commissure. We treated 6 cases of macrostomia form May 1, 1996 to April 30, 1999 using straight line closure and reconstruction of the orbicularis oris muscle. Periods of follow-up were from 12 months to 35 months, with an average of 20,2 months. Every patient was analyzed clinically by ordinary scale method and anthropometrically by the ratio of abnormal distances to normal distances between cheilion and crista philtri. In 3 clinical assessments : symmetry of the commissure was excellent: degree of the scar at rest was good: and degree of depression with animation was excellent. The anthropometrical ratio was 1:1.05. Despite the fact that the linear scars were perpendicular to the minimal skin tension lines, the scars were inconspicuous. The muscle repair provided reconstruction to the modiolus and gave a natural appearance to the commissure, however it did not seem to provide sufficient bulkiness around the commissure. The straight line skin closure and repair of the orbicularis oris muscle provide effective functional and aesthetic reconstruction.

Spontaneous spinal epidural hematoma is a rare entity. Various definitions for spontaneous epidural hematoma have been reported in the literature. The expression of nontraumatic spinal epidural hematoma seems to be less ambiguous and includes idiopathic hematomas and hematomas secondary to coagulopathy, vascular malformations, and tumors. We report three cases of nontraumatic spinal epidural hematomas observed from 1991 to 2000. The causes of the spinal epidural hematomas were not clear in two cases among them, but in the another one case, the cause was determined to be an acquired coagulopathy. We reviewed 24 cases reported in the Korean Journal of Neurosurgery and our three cases with particular emphasis on the various causes such as coagulopathy, vascular malformations and tumors. Among the 27 cases, numerous causes were detected such as three cases of vascular malformation, one case of anticoagulant treatment, five cases of combined lumbar disc herniation, two cases associated with pregnancy and postpartum, one case associated with hypertension, and one case associated with ossification of ligamentum flavum. No causes were detected in the ten cases. The authors reviewed the literature.

Journal of the Korean Cleft Palate-Craniofacial Association 2002;3(2):185-189
An upward slant of palpebral fissure is usually said and believed to be a hallmark of Mongolian race. The slant of palpebral fissure is very important in the evaluation and treatment of patients with congenital deformities. And these statistical values of slant of palpebral fissures are very helpful in case of traumatic or congenital lateral canthal deformities and upper face lift or forehead lift. The normal values of slant of palpebral fissures are variable according to races, sex and ages. Even if upward slant of palpebral fissure are one of characteristic features of Koreans, there are a few articles concerning them in Korea yet, unfortunately. So, we have inevitably utilized the Caucasian or Japanese statistical data. Authors measured the slant of palpebral fissure in Koreans, and statistically analyzed them in 996 individuals including 468 males and 528 females. The mean values of slant of palpebral fissure was 8.5+/-2.0degreein males and 8.8+/-2.5degreein females. The mean values of slant of palpebral fissure was greater in female than male. However, there was no statistical difference between males and females. The slant of palpebral fissure reached the peak level at childhood and teenagers in a great portion. After the peak level, the changing pattern of slant of palpebral fissure was decreasing gradually. In summary, we consider 8.65degreeas normal standard value of slant of palpebral fissure when performing lateral canthal surgery in Koreans.
