Comparison of ultrasound transmission velocity with computed metacarpal radiogrammetry and dual-photon absorptiometry

The aim of our study was to evaluate the validity of a quantitative US technique for measuring the bone density of the proximal phalanges of the nondominant hand compared with computed metacarpal radiogrammetry and dual-photon absorptiometry (DPA) of the lumbar spine. Mean US bone velocity (UBV) correlated with mean metacarpal cortical index (MCI), with mean metacarpal bone density (MBD) and with bone mineral density (BMD) of the lumbar spine, whereas it was correlated negatively with age and menopause duration. The average UBV was significantly higher in premenopausal women than in postmenopausal women, and higher in normal lumbar DPA patients than in reduced lumbar DPA patients. We conclude that the US evaluation of the nondominant hand proximal phalanges may be a new alternative way for measuring bone mass in screening of osteoporosis. Correspondence to: A.

Body sculpture: The words become reality

The last decade has been marked by the development of liposuction. A better knowledge of the anatomy of fat tissue, together with an improvement in different devices, has made our results more predictable. However, such areas as the chin, anterior and inner thigh, and knee have remained difficult. This is especially true when large volumes of fat need to be removed. Blood loss has remained a problem as well. The development of ultrasound (U.S.) liposuction is a big step toward even more predictable results and to where blood loss can be negligible.Lipectron B.U.S. Endotron is a device manufactured by and available from MEDICA MAT s.a., Avenue Augustin Dumont 59, F-92240 MALAKOFF.     

超声引导下成人与儿童肾活检术的评价

目的评价经超声引导成人与儿童肾活检术的方法和安全性。方法83例肾脏病患者超声引导下经皮穿刺活检,经右肾或左肾下极进针,方向自外下向内上,沿肾下极皮质取材。结果68例获取足够肾组织,总成功率及3针以内成功率分别为82%、53%,成人与儿童间无差异(P>0.05)。肾活检并发症儿童以疼痛为主,成人以血尿为主。结论超声引导下成人与儿童肾活检术是安全可靠的,其病理诊断对临床治疗具有明确的指导意义。

Estimation of the amniotic fluid volume using the Cavalieri method on ultrasound images.

OBJECTIVES: Presently, a design-based and practical method for measuring amniotic fluid volume (AFV) for routine clinical examinations has not been proposed. In this study we describe a new method, which combines the Cavalieri method with ultrasound imaging to estimate AFV. METHODS: We measured the AFVs of 14 women in the third trimester of pregnancy, and repeated our measurements three times for each woman. Parallel planimetric ultrasonographic images were obtained at every 2 cm along the longitudinal uterine axis. AFVs were calculated as the total of the multiples of the estimated cut surface areas by the section thickness. RESULTS: The mean estimated AFV was 380.5 cm3. The coefficient of error of each measurement was calculated and the mean was 0.108. The coefficient of correlation between the amniotic fluid index and our AFV estimations was 0.87. CONCLUSIONS: Design-based and efficient estimation of AFV is possible with the combination of consecutive ultrasound images and the Cavalieri method.     

男性乳癌特征分析(附31例报告)

目的：了解男性乳癌特点，提高其早期诊断率及治疗效果。方法：对31例男性乳癌进行了回顾性分析。结合随访资料，应用Kaplan-Meier法进行生存分析。结果：男性乳癌少见，病因不清，发病多在50岁以上，临床病例晚期多见，容易侵犯皮肤及胸肌，乳头常受累，可伴乳头溢血，淋巴结转移较早，雌激素受体阳性率高，治疗以手术为主，主要是改良根治术，包括化疗，内分泌治疗和放疗的综合治疗，预后与腋淋巴结转移状况有关。结论：男性乳癌晚期多见，治疗以综合治疗为主。预后与腋淋巴结转移状况相关。     

遗传性非息肉病性大肠癌(10个家族27例报告)

分析遗传性非息肉病性大肠癌(HNPCC)的临床特点。方法:对10个家族27例HNPCC患者(A组)进行回顾性分析,并设30例一般大肠癌为对照组(B组)进行比较。结果:<50岁患者A组占59.3%(16/27),B组占23.3%(7/30),P<0.05。脾曲以上癌灶A组为40.0%(12/30),B组为16.1%(5/31),P<0.05。大肠多原发癌A组占10.0%(3/30),B组占3.2%(1/31)。大肠外肿瘤A组6例,B组2例。结论:HNPCC具有典型的临床特征,这些特征可以对HNPCC患者进行早期诊断及治疗,以得到较好的预后。     

38例肺源性脑转移瘤临床病理分析

目的 肺源性脑转移瘤临床病理特征。方法 研究38例肺源性脑转移瘤的临床和病理特点,男性27例,女性11例;年龄在30-74岁之间。其中5例转移性癌作免疫组织化学染色和电镜观察。结果 20例为腺癌,12/20为乳头状腺癌;5例为腺鳞癌,7例为鳞形细胞癌,4例为燕麦细胞癌,2例为不典型类癌;5例乳头状腺癌作免疫组织化学染色示CK(5/5)和CEA(4/5)为阳性;电镜显示转移性乳头状腺癌具有肺泡Ⅱ型上皮细胞分化潜能。结论 肺癌中腺癌更易发生脑转移,免疫组织化学在鉴别诊断中有一定的辅助作用,转移性乳头状腺癌具有异质性。
