The superficial sural artery flap is supplied by the superficial sural artery that accompanies the sural nerve. The superficial sural artery connects distally with a peroneal artery septocutaneous perforator via a suprafascial network of vessels that permits the flap to be raised on its distal pedicle. We treated 10 patients who showed soft tissue defect of the lower third of the leg, around the ankle and the hindfoot with this flap. The causes of the soft tissue defect were trauma in 6 cases, pressure sore in 2 cases, squamous cell carcinoma in 1 case and osteomyelitis in 1 case. The sites of the soft tissue defect were the lower third of the leg in 5 cases, around the ankle in 2 cases and the hindfoot in 3 cases. The size of the soft tissue defect was from 5x6 cm to 8xl2 cm. All 10 flaps survived. Two flaps showed slight venous congestion which cleared in a few days. The time for flap dissection was 15 minutes in average. The results of our cases show that the distally based superficial sural artery flap is useful for the soft tissue coverage of the lower third of the leg, around the ankle and the hindfoot. The advantages of the flap are that the blood supply is reliable, elevation is easy and quick, the major arteries are not sacrificed and the donor site morbidity is negligible.

We analysed the 16 cases of the perilunate dislocations (PLD) and fracture-dislocations (PLFD) to study the distribution of the different forms and provides additional information about the perilunate pattern of injury. The cases were followed at least 1 year and an average of 2 years and 3 months. The results were as follows: l. All of the cases, the direction of the dislocation was dorsal. The PLD was 4 cases (25%) and PLFD was 12 cases (75%). The transscapholid perilunate fracture-dislocation (TS-PLFD) was the most common type. 2. Scaphoid fracture was present in 9 cases (56%), It was transverse fracture in the middle 1/3. 3. Missed or delayed diagnoses were noted in 3 cases (18%). 4. Overall functional results were graded as exellent in 2 cases (13%), good in 9 cases (56%), fair in 3 cases (18%) and poor in 2 cases (13%).

In order to investigate the occurrence characteristics of cancer in terms of industry in Kwangju-Chonnam area, medical utilization records of industrial medical insurance corporations during the period of 1987 to 1988 were reviewed for the identification of neoplastic disease. The cases obtained from the medical records were followed up for the verification and to get additional information. Standardized incidence data were compared by occupational characteristics. Multiple logistic regression analysis was applied to analyze the difference of incidence or distribution of cancer as a whole or of some selected cancer. Total cases of cancer identified were 242 during the study period. Annual incidence rate was calculated as 123.1 per 100,000 person. The frequent types of cancer were cancers of stomach, liver, lung, colon and rectum, bladder and lymphoma in descending order. Employees of mine and other sand handling industries showed significantly higher risks for cancer of stomach and cancer as a whole. Employees of the transportation industry showed the higher risk for cancer of liver. Workers in small-sized industry (< or = 100) had a higher risk for cancer than who in large-sized industry (>100). These findings suggested the effect of occupational environmental exposure to cancer development.

A reproducible noninvasive technique for measuring right ventricular ejection fraction (RVEF) was developed using first pass quantitative radionuclide angiocardiography. Tests were carried out in the right anterior oblique position with a computerized multicrystal scintillation camera with high count rate capabilities. RVEF was calculated on beat to beat basis from the high frequency components of the background-corrected right ventricular time-activity curve. The following results were obtained; 1) In 10 normal adults, RVEF averaged 50.9+/-8.2. In 20 patients with chronic obstructive lung diseases (COPD), RVEF was 37.9+/-6.1% and significantly lower than that of normal persons(P<0.005). 2) There was meaningful correlation between RVEF and forced expiratory volume (FEVI) in patients with COPD (r=0.51). And there was significant difference of RVEF between 13 patients with FEVI less than IL/min (6 patients with right ventricular failure, 7 patients with patients without that) and 7 patients with FEVI IL/min or more (35.7+/-6.0%, 42.1+/-3.2% respectively. P<0.005). 3) All 6 patients with clinical manifestation of right heart failure had abnormal RVEF and had FEVI less than IL/min, which was significantly lower than that of 14 patients without clinical manifestation of right heart failure (33.6+/-4.8%, 39.8+/-5.6%, respectively. P<0.005). 4) In 14 patients without clinical manifestation of right heart failure, 11 patients among whom 7 patients had FEVI less than IL/min, had abnormal RVEF.

OBJECTIVE: The purposes of this study are to compare imaging features with operative findings and to determine significance of imaging studies for early detection of craniosynostosis(CS). METHODS: Plain radiograph of skull and three-dimensional(3D) CT reconstruction were analyzed in 10 consecutive patients with CS to assess the presence and the extent of synostosis. The radiological findings were investigated and compared with operative findings. RESULTS: The locations of lesion were coronal suture in 6, sagittal suture in 3 and multiple sutures in one patient, and the age ranged 1 to 53 months(mean age: 17.4 months). Reconstructive procedures with or without advancement of supraorbital rim were performed in coronal CS patients and PI-procedures or synostectomy were done in sagittal CS patients. Radi-ological abnormalities such as sutural indistinctness or sclerosis, bony ridge, bossing and other bony deformities were nearly consistent with surgical findings. CONCLUSION: The interpretation of imaging study are very important for early detection of craniosynostosis, especially, the plain radiographs of skull. Also 3D CT imaging is helpful in diagnosis and surgical planing of craniosynostosis. There are no significant differences between imaging features and operative findings in CS patients.

A conventional approach for the treatment of long-span edentulous areas is the use of removable dentures. However, placing implants in these areas results in superior functional outcomes by increasing the stability, support, and resistance of the prostheses and improving the masticatory efficiency. Treatment modalities utilizing implants can be further classified into either removable or fixed-type prostheses. Several factors such as the amount of alveolar bone resorption, inter-arch relationship, patient preferences, and socioeconomic status should be considered when determining the appropriate treatment approach. Monolithic zirconia has been considered a suitable material for implant-supported fixed dental prosthesis, because of the drastic improvement in its mechanical properties. It exhibits fewer incidences of fracture and chipping of the prostheses, and has greater bulk of material than metal-ceramic crowns and zirconia-veneered ceramics. Moreover, highly translucent monolithic zirconia is also available in the market, and its application is gradually increasing for anterior tooth rehabilitation. The present report describes a patient who underwent full-mouth rehabilitation with fixed dental prostheses (eight upper and three lower implant placements). All teeth, except bilateral mandibular canines and left mandibular first and second premolars, were extracted after the diagnosis of generalized chronic moderate-to-advanced periodontitis of the remaining teeth. The patient reported satisfactory esthetic and functional outcomes during the one-year follow-up visit.

We had replaced 159 hips in 130 patients with cementless porous-coated AML porsthesis at Kwang Ju Christian Hospital between April 1987 and Feb. 1992. Among them, 100 cases(80 patients) could be analyzed clinically and radiologically with an average follow-up of 38.5 months(range 10 months to 74 months). The purpose of this study was to evaluate the relationships of initial fit, follow up stability and clinical results. The results were as follows. 1. The average postoperative Harris hip score was 90 points(preop. 42) at the follow-up of 1 year or more, the pain score 41 points(preop. 15). 2. When the surgical fit of stem was achieved properly, fixation by bone ingrowth could be expected. Simultaneously adequate fit of acetabular cup provided stable fixation. 3. The incidence of thigh pain was high in patients with an unstable implant of stem and the hip pain was more common in group of a definitely unstable cup. 4. Stress shielding was seen in 44 cases(44%). Of the 44 cases, 38 cases(86%) revealed in bone ingrowth. In conclusion, this study showed good clinical result of THR using AML prosthesis at the average follow-up of 38.5 months and it seemed to be influenced by initial fit significantly. But long-term follow-up is needed for accurate clinical and radiological evaluation.

The authors experience 3 cases of angiographically occult vascular malformation(AVOM) of the brain during the last 3 months in 1990. All cases were diagnosis of either operative or pathological finding and were associated with intracerebral hemorrhage. The authors recommend that surgery should be considered even to those angiographically negative intracerebral hemorrhage cases, once clinical features are highly suggestive of AOVM. Surgery can be an effective and define therapy for these entities, which are prone to cause recurrent hemorrhage and persistent neural deficits.
