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.

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.

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%).

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.

PURPOSE: To evaluate the repeatability of macular thickness measurements using time domain (TD) OCT and spectral domain (SD) OCT in diabetic macular edema. METHODS: In 42 eyes of 42 patients with diabetic macular edema, three consecutive macular measurements were performed with TD OCT and SD OCT, and measurements for macular thickness and total macular volume obtained by the two OCTs were compared. The within-subject standard deviation (Sw), coefficient of variation (CVw), and intraclass correlation coefficient (ICC) were calculated to assess repeatability, with agreement between measurements assessed with Bland Altman plots. The correlations were also evaluated via the Pearson's correlation coefficient. RESULTS: The Sw of TD OCT and SD OCT for foveal thickness, total macular volume were 29.67 micrometer/16.44 micrometer, 1.26 mm3/0.23 mm3, respectively, and were significantly lower in SD OCT. The ranges of the respective CVw and ICC values were 1.10-2.78%, 0.78~0.96 for TD OCT, and 0.29~0.94%, 0.92~0.99 for SD OCT. The SD OCT showed better repeatability for macular thickness measurements (all p< or =0.001). The 95% limits of agreement for foveal and total macular volume were 88.9 micrometer, 2.4 mm3, respectively. The Pearson's correlation coefficients of macular thickness and total macular volume between the two OCT methods were statistically significant (p=0.88-0.99). CONCLUSIONS: Although both OCTs proved reliable for macular thickness measurements in diabetic macular edema, SD OCT shows better repeatability than TD OCT. Although macular thickness measurements obtained from the two OCTs cannot be used interchangeably, there were statistically significant correlations between measurements obtained using the two OCTs.

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.
