Urethrocutaneous fistula is the most common complication of hypospadias surgery, Many techniques have been tried to prevent urethrocutaneous fistula. We introduce the technique of neourethral coverage using adjacent subcutaneous tissue or a dorsal pedicled subcutaneous flap in hypospadias repair. This method was used in a series of 25 cases between April 1996 and April 1997. We experienced only one urethrocutaneous fistula. The additional coverage of the neourethra with the subcutaneous tissue achieves the goal of non-overlapping suture lines and allows for increased vascularity. So, this technique appears to be effective in preventing urethrocutaneous fistula in hypospadias repair.

If the centric prematurity occurs after orthodontic treatment, it creates centric slide regarded as a possible factor in the cause of temporomandibular disorder and/or postorthodontic relapse. The purpose of this study was to investigate the manner of centric prematurity and centric slide in postorthodontic patients. The 36 orthodontic patients who had been treated with edgewise appliance at least 3 months previously were used in this study. After recording centric relation by the leaf gauge technique, the centric prematurity and centric slide were studied using SAM2 articulator and mandibular position indicator. The results were as follows: 1. The highest percentage of centric prematurities were found on the second molars. 2. The buceal incline of the palatal cusp was the most frequent area of centric prematurities in the maxilla, while the lingual incline of the buccal cusp was the most frequent area in the mandible. 3. There were no trends in the direction of centric slide on the mandibular position indicator. 4. There were no significant differences in centric discrepancies between the premolar extraction and nonextraction group.

After surgical operation in patients with arteriovenous malformation (AVM), normal pressure perfusion breakthrough (NPPB) is one of the major complications. Brain perfusion SPECT with acetazolamide stress was known to be useful to evaluate the vascular reserve in several neurological and neurosurgical conditions. The authors performed acetazolamide brain perfusion SPECT in patients with AVM and compared the brain perfusion in the post-operative clinical courses. The acetazolamide brain perfusion SPECT was helpful in defining the prognosis of the patients with AVM. We describe 4 patients with AVM who had acetazolamide brain perfusion SPECT to examine the prognosis.

STUDY DESIGN: Literature review. OBJECTIVES: The aim of this study was to present updated information on the research support programs offered by the National Research Foundation of Korea. SUMMARY OF LITERATURE REVIEW: The research support programs offered by the National Research Foundation of Korea are an important cornerstone for obtaining other grants from the government and commercial companies. However, no information has yet been provided in the literature about these programs. MATERIALS AND METHODS: Review of the relevant literature. RESULTS: The research support programs offered by the National Research Foundation of Korea are complex. However, it is possible to find appropriate grants. It is necessary to focus on the individual basic research program. CONCLUSIONS: Novel proposals have a greater chance of receiving funding, especially if the appropriate background and preliminary data are provided.

Enteric fistulae result from gastrointestinal perforations in which communication is established between the site of perforation and another hollow viscus, potential space, or skin surface. Certain types of enteric fistulae are difficult to demonstrate by conventional radiographic methods, and CT is unique in its ability to demonstrate the extent and nature of extraluminal changes. The purpose of this study is to illustrate the CT findings of enteric fistulae occurring in a variety of abdominal and pelvic organs.

BACKGROUND: Rehabilitations in subacute phase are different from acute treatments regarding the characteristics and required resource consumption of the treatments. Lack of accuracy and validity of the Korean Diagnosis Related Group and Korean Out-Patient Group for the acute patients as the case-mix and payment tool for rehabilitation inpatients have been problematic issues. The objective of the study was to develop the Korean Rehabilitation Patient Group (KRPG) reflecting the characteristics of rehabilitation inpatients. METHODS: As a retrospective medical record survey regarding rehabilitation inpatients, 4,207 episodes were collected through 42 hospitals. Considering the opinions of clinical experts and the decision-tree analysis, the variables for the KRPG system demonstrating the characteristics of rehabilitation inpatients were derived, and the splitting standards of the relevant variables were also set. Using the derived variables, we have drawn the rehabilitation inpatient classification model reflecting the clinical situation of Korea. The performance evaluation was conducted on the KRPG system. RESULTS: The KRPG was targeted at the inpatients with brain or spinal cord injury. The etiologic disease, functional status (cognitive function, activity of daily living, muscle strength, spasticity, level and grade of spinal cord injury), and the patient's age were the variables in the rehabilitation patients. The algorithm of KRPG system after applying the derived variables and total 204 rehabilitation patient groups were developed. The KRPG explained 11.8% of variance in charge for rehabilitation inpatients. It also explained 13.8% of variance in length of stay for them. CONCLUSION: The KRPG version 1.0 reflecting the clinical characteristics of rehabilitation inpatients was classified as 204 groups.

We describe the imaging features of two cases of biliary ascariasis. Ultrasonography and CT showed no specific abnormal findings, but MR cholangiography clearly demonstrated an intraductal linear filling defect that led to the correct diagnosis. MR cholangiography is thus a useful technique for the diagnosis of biliary ascariasis.

PURPOSE: Full-thickness skin grafts are usually used in facial reconstruction, but on occasion, split-thickness skin graft is also used from the scalp due to the limitation of donor site. However, there were complications, such as alopecia, folliculitis and blood loss. In addition, it can not be used in patients with baldness. Under the circumstances, we used medial arm skin as split-thickness skin graft donor site in lieu of scalp. We investigated the efficacy of the medial arm skin as a donor site of facial skin graft in comparison with scalp. METHODS: From 2000 to 2005, the split-thicknesss skin grafts were performed using the medial arm skin in 10 patients and the scalp in 10 patients. We inspected the skin color match, texture match by the visual analogue scale. Scar contracture was estimated by the Visitrak grade(R)(Smith & Nephew). The statistical analysis was performed by SPSS 12.0. RESULTS: There was a more satisfaction in color match, texture, and scar contracture in medial arm skin than in scalp. CONCLUSION: According to these results, medial arm skin may be used efficiently as an alternative donor site of scalp in the facial reconstruction.
