It has been generally believed that the continuous flow of blood characterised by arterial inflow and venous outflow is essential for the survival of flaps. Since Baek et al.(1985) demonstrated the survival of a flap based on only a single vein without arterial inflow, there have been a lot of reports of successful skin flaps that depend on only venous blood flow. The location of pedicle is one of the important factors on the survival of flaps, but there have not been an effective study on the survival rates of venous island flaps according to their location of pedicles. In this study, we compared the survival rates of proximally based venous island flaps with those of distally based ones and attempted to decrease the difference, if any, in the survival rates between them. Distally or proximally based 4x3 cmvenous island flap, whose pedicle was a marginal branch of central vein, was elevated from the auricular cartilage of New Zealand white rabbit. IN the half of 20 rabbits, superoxide dismutase (SOD, 20,000 U/kg) was injected intravenously 30 minutes and 60 minutes after the flap elevation. On the 7th postoperative day, survival areas of the flaps were measured by image analysis system and the vascular network with the flaps were examined by micro fil cast. 40 flaps were divided as follows: proximally based venous flaps, distally based venous flaps, SOD treated proximally based venous flaps, SOD ttreated distally based venous flaps. The results were as follow: 1. The survival rate(79.39+/-9.24%) of the proximally based venous flaps were significantly higher than those(60.79+/-14.10%) of the distally based ones (p< 0.01). 2. SOD improved survival of the flap significantly (p< 0.05), and there was no statistical difference in the survival rates between proximally based venous flaps and SOD treated distally based venous flaps (p = 0.1785). 3. Revascularization was actively developed in the proximally based venous flaps and those flaps treated with SOD, but was minimal in the distally based venous flaps. These results suggested that the vascular pedicle would rather be located proximally than distally in designing the venous island flaps and that SOD treatment may be effective for the enhancement of survival of venous island flaps, especially in distally based ones.

There are a number of eating-houses in the basin of river Ahnseong that sell rawsweetfish, Plecoglossus altivelis, to local residents and visitors. These facts called attention to the possibility of wide spread of metagonimiasis in that area. In an attempt to determine whether the metacercaria of Metagonimus yokogawai does present in the sweetfish caught in the river Ahnseong, a total of 77 fish were examined in the period from April to September 1978. All the fish were infected with the encysted larvae. The average number of larvae persweetfish was 1,815, of which the metacercaria rate for the fluke in the flesh was 56.9 per cent and in the scale, 30.5 per cent. These results indicate that all the sweetfish in the river Ahnseong harbour the metacercaria of Metagonimus yokogawai.

PURPOSE: The aim of this study was to develop a baptist electronic Nutritional Screening Program (B-eNSP) that could be easily used to identify patients with nutrition at risk or malnutrition on their admission to hospital using an integrated medical information system and to evaluate validity, reliability and efficiency of B-eNSP. METHODS: From June 1 2009 to June 21 2009, we enrolled 496 patients for prospective research. We analyzed age, sex, weight, height, weight loss in the last 3 months, serum albumin, alteration of dietary intake, gastrointestinal symptom, functional capacity, diagnosis and its relationship to nutritional requirements, physical examination and Subjective Global Assessment (SGA). B-eNSP included body mass index (BMI), weight loss in the last 3 months, serum albumin. Each component was scored. Sensitivity and specificity were calculated to evaluate the validity of the B-eNSP. The receiver operating characteristic (ROC) curve was drawn by using B-eNSP to choose a cut-off value that maximizes sensitivity and specificity and Yoden Index. Comparison with SGA and the reliability of the B-eNSP was done using kappa statistics. RESULTS: The maximum Yoden Index was 0.866 and the cut-off value of the ROC curve was 2. A B-eNSP score higher than 2 was defined as nutrition at risk or malnutrition. Reliability of the B-eNSP was in accordance with SGA by kappa 0.845. CONCLUSION: The B-eNSP can be used efficiently to identify patients with nutrition at risk or malnutrition by simply using an integrated medical information system.

The common sites of solitary bone cyst(SBC) are humerus, femur and less common sites are tibia, calcaneus, ilium, fibula, radius and ulna. Ischium rib, scapula, spine, clavicle and patella are rare sites of solitary bone cyst. As mentioned above, SBC of patella is very rare and on view of literatures we could find only one reported case which was treated by patellectomy. We also experienced one case of SBC located at patella, so we report this case with review of literatures.

The cornell medical index is self-administered instrument that collects a large body of significant medical and psychiatric data. The original C. M. I. consists of 195 questions, but authors selected 60 questions from the original C. M. I. to simplify it. The purpose of this investigation is to clarify if there are any correlations between low back pain and extraskeletal disorders. This investigation was conducted on 144 in-and out-patients who were treated at the Department of Orthopaedic Surgery,Our Lady of Mercy Hospital, Catholic Medical College from Jan. to July 1977. Among them 75 patients were male,69 patients were female, and 22 patients had decompression laminectomy and discectomy. The results of this investigation are as follows; 1. The majority of patients with low back pain are 2nd to 4th decade. (Male: 30±10.7) (Femal:36.1±10.5) 2. Average number of complaints is 19.9/60 in male, 21.8/60 in female. 3. Complaints in section F(Fatigability) and G(mental) are predominant in all cases. 4. There are no significant difference in number of complaints between the operative and non-operative case, and between each decade.
