During the last 10 years, we have experienced 169 cases of congenital melanocytic nevi of the face at Seoul National University Children's Hospital. In these patients, various modalities of treatment have been used, including excision, staged excision, skin graft, local flap, and composite graft. Dermabrasion, electrocoagulation, and laser therapy were excluded because these were not definitive treatments. We reviewed over 169 cases based on the involved on the aesthetic units of the face and the length of the defect perpendicular to wrinkle lines. We have attempted to create a stadard for the selection of the appropriate treatment modality. Cases which involved orbital unit(38 cases), cheek(30 cases), and parotid-masseteric unit(18 cases) were analysed statistically. To avoid the statistical error, units of sufficient number of cases and involving only one unit were included. In each unit, we used Receiver Operator Characteristic Method to identify the turning points of the length of the defect perpendicular RSTL which decided the treatment modality. And we used t-test to show the statistical difference between the lengths of the defect perpendicular to RTSL in each modality. The turning point were 0.9-1.0 cm between excision/staged excision, 2.0 cm between staged excision/FTSG, in orbital unit, 1.3 cm between excision/staged excision in cheek unit, 1.6-1.9 cm between excision/staged excision in parotid-masseteric unit. And it was identified by ANOVA test and t-test that the above groups were statistically different. Till now, the treatment modality of the congenital melanocytic nevus was based on the experiences of the surgeon. But now, we have presented the stadard of the treatment according to the size in each aesthetic unit. Therefore we can choose the approproate treatment modality among the severals in accordance with the standards.

Takayasu's arteritis is a chronic, granulomatous, large-vessel arteriopathy of unknown cause. A 45-year-old women developed multiple subcutaneous nodules preceded by fever, chills, weakness and weight loss. There were several developed pyoderma gangrenosum-like ulcerations which resulted from the breakdown of subcutaneous nodules on both forearms. A skin biopsy specimen from a forearm nodule revealed characteristics of polyarteritis nodosa including necrosis of the muscular arteries of the deep dermis and subcutaneous tissues destruction of the elastic lamella, thrombus formation, and an acute and chronic inflammatory cell infiltrates. Seven years later, the diagnosis of Takayasu's arteritis was suggested by the absence of the left radial pulse and confirmed by angiography.

In order to group the pelvic obliquity into clinically useful classification and to develop appropriate guidelines for treatment, we evaluated 55 patients who had been treated between 1985 and 1993 for pelvic obliquity after poliomyelitis. Age at surgery ranged from 15 years to 49 years (average 27 years). Fixed pelvic obliquity after poliomyelitis was classified into two major types according to the level of the pelvis relative to the short limb and into four subtypes in each type according to the direction and severity of scoliosis. Forty-six patients had obliquity with the pelvis down (type I), and nine patients had the pelvis up (type II) on the short limb side. Subtype A: straight spine with localized lower lumbar compensatory angulation, mainly at the L4-5 intervertebral space. Subtype B: mild scoliosis with convexity to the short limb side, Subtype C: mild scoliosis with convexity opposite to the short limb side. Subtype D: moderate to severe paralytic scoliosis, which has a convexity to the short limb side in type I and opposite to the short limb side in type II. In the pelvis of type I-A, I-B and I-C deformities, abduction contracture of the hip was released on the side of affected short limb, and lumbodorsal fasciotomy was performed on the contralateral side of short limb, where iliolumbar angle converged and the pelvis was elevated, if necessary. In most cases, hip instability existed on the side of short limb and it was treated with triple innominate osteotomy, which also contributed to leg length equalization by lengthening. In type II-A, II-B and II-C deformities, it was necessary to perform a triple innominate osteotomy on the side of affected short limb with adducted unstable hip in most cases. Lumbodorsal fasciotomy was performed above the iliac crest of elevated hemi-pelvis with short limb, where iliolumbar angle converged. In case of abduction contracture of contralateral hip, contracted fascia was released. In the pelvis that had a type I-D or type II-D deformities, treatment might include bony surgeries such as spinal fusion or triple innominate osteotomy, with appropriate soft tissue release. We propose a systemic and comprehensive classification for fixed pelvic obliquity after poliomyelitis. According to this classification, we and decide to combine corrective surgeries, and find the side where the surgery should be performed.

Heel cord advancement(HCA), which has been applied for the correction of equinus deformity in spastic cerebral palsy, has some theoretical advantages. However, HCA has also theoretical disadvantage that the procedure remove the tensile force exerting to the calcaneal apophysis. In order to evaluate the effect of HCA on the calcaneal growth, we compared the changes of calcaneal and foot lengths between the operated feet and non-operated feet after HCA. Among the 54 patients who had been treated with HCA at Seoul National University Childrens Hospital from March 1990 to August 1995, we excluded the cases who had been treated bilaterally, and also excluded hemiplegic patients in whom the ipsilateral feet were already shortened and the growth rates are different between the ipsilateral and contralateral foot. Seven patients who met the criterior of this study were included for the evaluation. There were 3 diplegics and 4 paraplegics, and average age at operation was 10 years and 6 months(range; 7 year 8 months-16 year 5 months). Average follow-up period was 3 years and 5 months(range; 2 years-4 years 9 mos). Total calcaneal lengths, anterior and posterior part of calcaneal lengths were measured on the standing lateral radiographs of the foot and ankle. Ratios of the operated limb over the non-operated limb were calculated for the three parameters. Ratios of posterior part of calcaneal lengths decreased significantly(P=0.031). Ratios of total calcaneal lengths decreased and ratios of anterior part of calcaneal lengths increased. However, the changes of two ratios were not significant. Ratios of posterior part calcaeal lengths over total calcaneal length decreases significantly(P=0.016). In conclusion, HCA can cause calcaneal growth retardation, especially posterior part of calcaneus, due to removal of physiologic tensile force of Achilles tendon.

There is an established relationship between a high salt diet and public health problems, especially hypertension and cardiovascular disease. We estimated daily salt intake in a group of adults and assessed its association with related variables in Pohang, Korea. We conducted a cross-sectional survey in 2013 with 242 adults. Urine was collected for 24 hr to estimate daily salt intake, and questionnaires about salt preference were administered. The mean daily salt intake was 9.9+/-4.6 g. There was no difference in salt intake between high systolic blood pressure (SBP) participants and normal SBP participants (10.5+/-4.7 g/d vs. 9.6+/-4.3 g/d, P=0.339), but high diastolic blood pressure (DBP) participants reported more salt intake than normal DBP participants (10.4+/-4.9 g/d vs. 9.7+/-4.1 g/d, P=0.049). Salt intake and body mass index demonstrated a positive correlation (P=0.001). A preference for Korean soup or stew was associated with high salt intake (P=0.038). Dietary salt intake in Korean adults is still higher than the recommendation from the World Health Organization. More efforts should be made to reduce the salt consumption of Korean adults.

Anthropological studies of the proximal femur in a given race is a prerequisite step in designing femoral component of the total hip arthroplasty. As these studies and subsequent data are lacking for Korean hips, the author attempted an anthropological measurement of the Korean proximal femur. The results of this study are as following; l. In the orthoscanographic study for 187 subjects, mean of the maximum femoral length was 43.73±2.13cm for male, 40.53±2.03cm for female, The proportion of femoral length to the body height was found to have a constant ratio −26.10% for male, 25.91% for female. 2. In Anthropological measurement of Korean femur for 58 subjects, mean angle of the femoral anteversion was 19.85±6.86 and the neckshaft angle was 129.6±3.09. 3. In the study of the anterior curvature of femur, position index was 51.95±14.5% for male, 52.61±9.25% for female and index of bowing was 2.58±1.01% for male, 3.01±1.25% for female. In comparision with other races the Korean femur was found to have relatively straight curvature and the apex of the maximum curvature was located more distally. 4. External circumferential diameter of the femur-measured at 15cm below the lesser trochanter-showed 8.79±0.59cm for male and 8.42±0.53cm for female. The sexual difference at this level was statistically significant. (P <0.05). 5. In selected cadaeveric femurs, the minimum transverse diameter of internal mold was 1.26±0.30cm and was located at 12.5cm below the lesser trochanter to 20cm can be estimated by the following equation. Y=2.234−0.191X+0.0078X² for male, Y=2.395−0.173X+0.007X² for female.

It is difficult to determine respiratory criteria of fitness for surgery and anesthesia in patients with intractable chronic obstructive pulmonary disease (COPD), who have high mortality and morbidity in the perioperative period. Also, it is commonly assumed that general anesthesia carries a greater risk of perioperative pulmonary complications than regional anesthesia in patients with COPD. A 79-yr-old COPD female patient complaining of right hip pain due to fracture of right femur neck and dyspnea on rest was admitted for surgery. Even after aggressive medical management for COPD during the preoperative period, dyspnea on rest and expiratory wheezing were not improved. The results of the pulmonary function test and the immediate preoperative arterial blood gas analysis were as follows: FVC 0.97 L, FEV1 0.38 L, FEF25-75% 0.11 L/sec, PaO2 47.6 mmHg, and PaCO2 68 mmHg. We report the anesthetic considerations for the epidural block for the severe COPD patient associated with hypoxemia and hypercarbia.
