Objectives: This study investigated the association between body mass index (BMI) (and its change) and risk of breast cancer in Korea women by age. Methods: Participants were 64,149 women aged 35~59 years at the baseline (1990~1992) of the Korea Medical Insurance Corporation study. They were stratified as 44,923 women aged 37~47 years and 19,226 women aged 48~61 years by age at year 1992. BMI change was defined as BMI at 1994 minus baseline BMI. Baseline BMI was categorized quartile and first quartile used as reference group for the analysis. BMI change was categorized quartile and second quartile used as reference group for the analysis. Hazard ratio (HR) calculated using Cox`s proportional hazard model. Results: Baseline BMI and breast cancer risk were not associated in women aged < 48 (HR = 0.83, p for trend = 0.182 for Q4 vs Q1), but associated in women aged ≥ 48 (HR = 2.08, p for trend = 0.002 for Q4 vs Q1). However, BMI change was not associated with breast cancer risk in either age group. Conclusions: These results suggest that obesity may be a risk factor breast cancer in premenopausal women but not in post menopausal women.

Sixty-five Intertrochanteric hip fractures were analyzed radiologically to study the factors affecting postoperative stability. Fractures were evaluated by measuring shortening and angulation, collapse of telescoping device when utilized, and migration of the fixation device within the femoral head. Fractures were classified according to their stability preoperatively and the reduction of lessor trochanteric fracture fragment postoperatively. The failure rate and postoperative stability were then compared on terms of severity of osteoporosis, type of fracture, existence of reduction of lessor trochanter fragment Results indicated that the severity of osteoporosis was not related to the group of fracture, which determines stability of fracture. Regarding the rate of bone union, anatomically reduced groups showed similar rates of bone union (73.8% in average) and degree of sliding of lag screw (4.13mm in average) regardless of fixation of lesser trochanter fragment. On the other hand, malreduced group which failed to obtain anatomical reduction had 26.1% of bone union rates and 10.95mm of sliding of lag screw representing importance of anatomical reduction rather than fixation of lesser trochanteric fracture. In conclusion, there was no correlationship between severity of osteoporosis and type of fracture. And it is suggested that unstable intertrochanteric fractures accompanied by large lesser trochanteric fracture fragment can be provided stability avoiding major complications such as loosening of implant or collapse of fracture fragment if it is fixed with anatomical reduction of fracture even without the fixation of lesser trochanteric fragment.

김학준,허창룡,김재균,장규선,Kim, Hak Jun,Hur, Chang Ryong,Kim, Jae Kyun,Jang, Kyu Seon 대한정형외과초음파학회 2012 대한정형외과 초음파학회지 Vol.5 No.2

목적: 족부에 발생하는 여러 질환 중 모톤씨 신경종은 종족골두 사이에서 지속적인 마찰로 인한 자극으로 발생되며 보행 시 통증과 감각이상을 호소한다. 일차적인 치료는 중족골 패드, 스테로이드 주사, 비스테로이드성 진통제를 사용하는 비수술적인 치료 방법이 권장되고 있다. 초음파의 발달로 인해 모톤씨 신경종을 진단하고 그 크기를 쉽게 확인 할 수 있으며 스테로이드도 정확한 부위에 주사할 수 있게 되었다. 이에 저자들은 초음파 영상 하의 스테로이드 주사에 대한 임상적 결과를 분석하고자 하였다 대상 및 방법: 2008년 10월부터 2011년 9월까지 임상적 및 초음파 검사 하에서 모톤씨 신경종으로 진단받은 17명(23례)을 대상으로 연구를 시행하였다. 모든 환자가 여성이었고, 평균 나이는 52.6세(36~72)이었다. 병변의 종축과 횡축의 크기를 측정하였고, 5 mg의 dexamethasone을 초음파 영상 유도 하에 신경종 주위에 주사하였다. 주사 전, 후의 자가 통증 점수(VAS pain score)를 기록하였고, 주사 후 환자의 만족도를 완쾌, 호전, 비호전, 악화로 분류 하였으며 SPSS 프로그램을 이용한 t-test를 이용하여 병변의 크기에 따른 steroid 주사의 효과를 비교 분석하였다. 결과: 1예에서 제1 중족지간에, 11예에서 제2 중족지간에 신경종이 발생하였고, 11예는 제3 중족지간에 발생하였다. 신경종의 평균 종축의 길이는 $0.8{\pm}0.4cm$, 횡축의 길이는 $0.52{\pm}0.17cm$이었다. 총 23례 중 증상의 완쾌 및 호전은 7례(30.4%)이었고 비호전 및 악화의 예는 16례(69.6%)이었다. 만족도가 완쾌 및 호전이었던 군의 신경종 종축의 평균길이는 $0.71{\pm}0.39cm$이었고 횡축의 평균 길이는 $0.47{\pm}0.24cm$이었으며, 만족도가 비호전 및 악화 이었던 군의 신경종 종축의 크기는 $0.83{\pm}0.42cm$, 횡축의 길이는 $0.54{\pm}0.14cm$이었다. 종축의 길이가 5 mm 미만, 횡축의 크기가 4 mm 미만인 신경종 군에서 주사 후 자가 통증 점수와 만족도가 종축이 5 mm, 횡축이 4 mm이상인 신경종보다 통계학적으로 의미 있게 임상 결과가 좋은 것으로 분석되었다(p<0.05). 결론: 모톤씨 신경종에서 초음파 영상은 진단 및 치료에 중요한 영상기법으로 생각되며 신경종의 횡축 길이가 0.5 cm, 종축 길이가 0.4 cm 미만인 경우에는 스테로이드 주사가 효과적인 것으로 사료된다. Purpose: The aim of this study was to evaluate the effectiveness of ultrasound-guide steroid injection according to Morton's neuroma size. Materials and Methods: From October 2008 to September 2011, 17 patients (23 cases) diagnosed with Morton's neuroma were investigated. All cases were female and mean age was 52.6 years old. Neuroma were measured by the horizontal and longitudinal length of the mass and underwent ultrasound-guided steroid (5 mg dexamethasone) injection. The efficacy of the injection was determined by Visual Analogue Scale pain score and patient satisfaction(subdivided 4 group-much improved, improved, not improved, aggrevation) Results: 7 of 23(30.4%) cases showed much improved and improved satisfaction and mean longitudinal and horizontal length were $0.71{\pm}0.39cm$ and $0.47{\pm}0.24cm$, respectively. 16 of 23(69.6%) cases showed not improved and aggrevation satisfaction and mean longitudinal and horizontal length were $0.83{\pm}0.42cm$ and $0.54{\pm}0.14cm$, repectively. There was a significant difference in VAS and patient satisfaction in case longitudinal and horizontal length were smaller than 0.5 cm and 0.4 cm. (p<0.05) Conclusion: The ultrasonography is a important modality in diagnosis and treatment of morton's neuroma. Ultrasound-guide steroid injection is effective in case longitudinal and horizontal length were smaller than 0.5 cm and 0.4 cm, respectively.

Centroid Method: Reliable Method to Determine the Coronal Curvature of Scoliosis: A Case Control Study Comparing with the Cobb Method

Hong, Jae-Young,Suh, Seung-Woo,Modi, Hitesh N.,Hur, Chang-Yong,Song, Hae-Ryong,Ryu, Joo-Hyung Lippincott Williams Wilkins, Inc. 2011 1528-1159) Vol.36 No.13

STUDY DESIGN.: Observational study with three examiners. OBJECTIVE.: To compare the reliability of the Cobb and centroid methods. SUMMARY OF BACKGROUND DATA.: The Cobb method is considered to be the gold standard in scoliosis measurement despite its low reliability. In adolescent idiopathic scoliosis (AIS) patients, the centroid method can be a good method for measuring scoliosis. METHODS.: Sixty whole spine postero-anterior radiographs were collected to compare the reliability of the Cobb and centroid methods in AIS patients. Sixty radiographs were measured twice by each of the three examiners using the two measurement methods. The data were analyzed statistically to determine the inter- and intraobserver reliability. RESULT.: In comparisons of inter- and intraobserver reliability of all 60 radiographs, the inter- and intraclass coefficients (ICCs) were higher in the centroid (>0.969) than in the Cobb method (>0.832), although both were in the excellent range. The mean absolute difference (MAD) values were higher in the Cobb method (<7.15° vs. <3.75°), and >5° in five comparisons. Regarding measures of mismatched radiograms, the inter- and intraobserver MAD values were higher in the Cobb method (<9.81° vs. <3.82°), and >5° in six comparisons. And, the ICCs were higher in the centroid method (>0.972) than the Cobb method (>0.758). In immature radiograms, the ICCs were higher in the centroid (>0.973) than in the Cobb method (>0.764), even though it was in the excellent range. And, the inter- and intraobserver MAD values were higher in the Cobb method (<8.49° vs. <3.99°), and >5° in seven comparisons. CONCLUSION.: The centroid method is more reliable for measuring scoliosis in AIS than the Cobb method, and it can substitute the Cobb method, which showed high variability.
