Purpose: To report the surgical skills needed, and the clinical results of, minimally invasive hip surgery with dynamic hip screws and the comparison with the classical technique in stable pertrochanteric fractures of the femur. Materials and Methods: Thirty-two patients with pertrochanteric fractures of the femur who were treated with dynamic compression hip screws between April 1999 and March 2004, and were evaluated retrospectively, and were followed up for more than 12 months. 16 cases were treated with a classical dynamic hip screw technique and 16 cases with a minimally invasive technique in random order. The mean age was 73.2 years, and there were 11 males and 21 females. The operative times, total hemovac bleeding loss, functional scores, and average hemoglobin decrease ratios were evaluated. The clinical assessments were performed with the Harris Hip Score (HSS) and bony union was evaluated with serial follow-up plain radiographs. Results: The average operative time was 63.9 minutes with the classical technique and 42.5 minutes with the minimally invasive technique. The total average hemovac blood loss was 640 cc with the classical technique and 143 cc with the minimally invasive technique. Clinically, the HHS was an average of 85.9 and 89.2 in groups 1 and 2, respectively, by the last follow-up and there were no statistically significant differences between the two groups (P <0.05) The hemoglobin decrease ratio was the same in both groups and there was no nonunion. Conclusion: Minimally invasive dynamic hip screw insertion was useful in stable pertrochanteric fractures, because it decreased blood loss and operative times; and there were no changes in fracture healing and functional outcomes.

Twin pregnancies have a higher rate of premature delivery than singleton pregnancies and a substantially higher perinatal mortality. Twin gestation complicted by a single anomalous fetus diffculties in obstetric management. Options available to patients include continuing the entire pregnancy, selective termination of the anomalous fetus, or termination of the entire pregnancy. The incidence of one anomalous fetus in twin pregnancy is rare. Gastroschisis is intestinal herniation through a defect in the anterior abdominal wall usually to the right of umblicus. There is no sac and the intestines are covered with a thickened inflammatory exudate. Most case of gastroschisis occur sporadically and chromosomal anomaly are less common. A case of one gastroschisis in twin pregnancies diagnosed by ultrasonography is reported with a brief review of the literature.

BACKGROUND: Retention of gestational weight can be a significant contributor to obesity related complications. Few studies have assessed the impact of behavioral factors in Korea. This study was performed to identify the impact of factors on weight change at 1 year postpartum. METHODS: A questionnaire was sent twice by mail to 635 women who delivered singleton infant without complications in Seoul Asan Hospital from January 2002 to March 2002 and 97 available responses were received. Parity, pre-pregnancy weight, fullterm weight and postpartum behaviors were collected from routine medical records and questionnaire. RESULTS: Mean age was 30.5 years and mean pre-pregnancy BMI was 20.9 kg/m2. Mean total weight gain during pregnancy was 13.6+/-4.3 kg/m2 weight change at 1 year postpartum was 1.9+/-3.8 kg. Nearly 17.5% of women experienced a major weight gain of 4.5 kg at 1 year postpartum. Women who had higher pre-pregnancy BMI (> or =23 kg/m2) were at high risk for major weight gained at 1 year postpartum (OR: 4.14). Women who gained 13.6 kg or more during pregnancy and with lower income were at high risk for major weight gain at 1year postpartum (OR: 5.28, 4.13 respectively). CONCLUSION: Pre-pregnancy BMI, gestational weight gain and household monthly income are significantly associated with weight change at 1year postpartum. These findings support the need of the guidelines for preventing major weight retention associated with pregnancy.

BACKGROUND: The catheter ablation usin radiofrequency(RF) energy in patients with atrioventricular nodal reentrant tachycardia(AVNRT) and atrioventricular reentrant tachycardia(AVRT) ahs been proved as a safe and effective nonpharmacologic therapeutic modality. The purpose of our study was to evaluate the success rate and complications of the initial experience and to determine the extent of myocardial damage of RF catheter ablation. METHODS: Electrophysiologic study was performed with the standard technique. Twenty five patinents(M:F=16:9, mean age:42 years old) underwent RF catheter ablation in St. May's Hospital from April to December in 1994. The RF generator in this study was RFG-3D model and catheters were 6F or 7F steerable catheters with 4mm kistal tip. In order to evaluate the extent of myocardial damage the WBC count, LDH, CK, and CK-MB fraction were checked before and after RF catheter ablation and the Tc99m myocardial scintigraphy was performed within 72 hours of the porcedure. RESULTS: Six of twenty five patients had AVNRT, in which the success rate of selective ablation of the slow pathway was 83.8%. Nineteen patients with AVRT had one accessory pathway. The ablation success rate of 14 accessory pathways in left free wall location was 85.7%, and that of 3 in left posteroseptal location was 66.6%. Two right sided accessory pathways were not ablated successfully. The level of CK-MB fraction after ablation was within normal limit. Only one case revealed grade 2 of hot spot in Tc99m myocardial scintigraphy. CONCLUSION: The RF catheter ablation in patients with AVNRT and AVRT is a safe and effective nonpharmacologic therapeutic modality. But right sided accessory pathways are more difficult to ablate than left sided accessory pathways, requiring more experiences and better technique. The extent of myocardial damage after RF catheter ablation reveals relatively minimal by cardiac enzyme study and Tc99mmyocardial scintigraphy.

Intrathyroidal parathyroid adenoma is an infrequent lesion which can be explained by abnormalities during embryonic migration of the parathyroid glands. Extracapsular hemorrhage from a intrathyroidal parathyroid adenoma is extremely rare, however, due to its location near upper airway, it might cause a life-threatening situation. Therefore, if patients presented with anterior neck painful swelling, skin ecchymosis associated with dysphagia and/or hoarseness, extracapsular hemorrhage from parathyroid adenoma should be considered as a possible diagnosis. Estimation of serum calcium level is essential as the presence of hypercalcemia can help to make the diagnosis pre-operatively. As rupture of a parathyroid adenoma and cyst may lead to local dissemination of tumor cells and an increased risk of recurrent hyperparathyroidism, careful longterm follow-up is required. We report an unusual case of spontaneous rupture of intrathyroidal parathyroid adenoma with a review of literature.

PURPOSE: To investigate the relationship between the varus appearance and the axial alignment of the lower extremity. MATERIALS AND METHODS: The axial alignments of the lower extremities of 46 normal male adults (volunteers) were measured from the radiographs and compared with the reports for Caucasians, and between the groups divided according to their subjective appearance. RESULTS: The femorotibial mechanical angle was 177.4+/-2.4degrees and the medial obliquity of the knee was 94.3+/-2.0degrees, which were the varus compared with the reported reference points. In the group containing those with the subjective varus appearance of the lower extremities, the femorotibial mechanical angle and the medial obliquity of the knee and ankle joint were the varus, and the metaphyseal-diaphyseal angle was greater than in the group containing those with the subjective straight appearance of the lower extremity (p<0.05). CONCLUSION: The axial alignment of the lower extremities of young male adult Korean is the varus, and the subjective varus appearance of the lower extremity is related to the varus axial alignment.

Spontaneous tumor rupture is a serious but rare complication of hepatocellular carcinoma (HCC) and has a low survival rate. Here, we report a case of massive HCC that ruptured and was treated successfully with transarterial chemoembolization (TACE). A 55-year-old man with abdominal pain was diagnosed with a 12-cm-wide ruptured HCC at segment 8. The overall liver function was scored as Child–Pugh A, but the single nodule tumor had ruptured; therefore, TACE treatment was initiated. After the first TACE treatment, residual tumors were found; thus, secondary TACE was performed 5 months later. No new lesions or extrahepatic metastases were found 16 months after the first TACE treatment, so hepatic resection was performed for curative treatment. The postoperative pathology results did not reveal any cancer cells; hence, TACE alone resulted in a cure. We report this case because the cure has been maintained for more than 3 years after resection.
