多层螺旋CT在人体内藏毒筛查中的应用价值

目的：探讨多层螺旋CT在人体内藏毒筛查中的应用价值。方法：对25例疑似体内藏毒人员行腹部多层螺旋CT扫描,通过对CT横断面及多平面重组图像的观察分析,明确体内是否藏有毒品。结果：25例筛查人员中,发现体内藏毒8例,1例为单纯肛门填塞藏毒,其余7例为经口吞服消化道内藏毒,其中1例同时伴有阴道内藏毒。8例藏毒者中,藏毒91粒者1例,40～65粒者5例,6～20粒者2例。结论：采用多层螺旋CT对疑似体内藏毒人员进行筛查,既能快速确定贩毒分子,又能明确所藏毒品的形状、数目及位置,无论是检查的速度,还是检查的准确性和安全性都优于普通x线检查。     

多层螺旋CT在体内藏毒的应用

体内藏毒是指毒品犯罪分子将违禁毒品(主要为海洛因)经过特殊加工、包装后,经口吞入或从肛门、阴道塞入体内,利用人体消化道、阴道携带毒品的方法,是一种较为隐匿的贩运毒品方式,近10年有明显上升趋势[1].毒品检出,以往多采用透视或X线平片,此方法有一定局限性[2],CT检查在此方面应用及报道较少[3],本组病例采用MSCT对体内藏毒者检查,目的探讨MSCT在体内藏毒方面应用价值.     

非法体内藏毒的筛查:腹部X线摄影是否足够准确?与低剂量CT的对照研究

目的评价腹部X线在检测体内非法藏毒中的诊断效能,以低剂量CT为参考标准。材料与方法本研究通过单位伦理委员会批准,并签署知情同意书。从2007年7月—2010年7月对怀疑吞入包装毒品的330人(男296人,女34人;年龄18～55岁,平均32岁)进行仰卧位腹部X线摄影和低剂量CT检查。报告腹部X线摄影是否发现体内毒品包,以低剂量CT为参考标准。记录低剂量CT中毒品包的密度和数量(≤12或>12),分析确定这些因素是否会对腹部X线的结果有影响。结果低剂量CT在53个(16%)嫌疑人的体内发现了毒品包。腹部X线摄影对于检测毒品包的敏感度是0.77(41/53),特异度是0.96(267/277)。53例毒品包中,低剂量CT发现16例(30%)与肠内容物呈等密度;19例(36%)的毒品包数量小于12个。低剂量CT中的等密度毒品包和较少的毒品包数量(≤12)均与腹部X线摄影的假阴性结果存在明显相关性(P值分别为0.004和0.016)。结论与低剂量CT相比,腹部X线摄影筛查体内藏毒嫌疑人的敏感度有限。低剂量CT是一种腹部X线摄影的有效替代方法。原文载于Radiology,2012,265(3):772-779.

Optimization of the system of medical service of students of Cadet Schools of the Ministry of Defense of the Russian Federation

One of the factors of the successful military career guidance Cadet schools students is preserving and promoting their health. Medical support of children and adolescents aged 10-17 years should include the full range of medical and preventive measures defined for this group. The state of providing outpatient care for pupils at the Cadet School in St. Petersburg was studied. These results show that full medical care in accordance with the standards can be based only on children's health clinics. It is important that the organization of medical support pupils cadet schools should be cooperate with civilian health care.

Estimation of accumulated dose of radiation by method of ESR-spectrometry of dental enamel of mammals

ESR-spectrometry was used to investigate radiation-induced paramagnetic centers in enamel of mammals: carnivores (polar bear and fox), ungulates (reindeer, European bison, moose), and man. Values at half the microwave power saturation of the radiation signal, P_1/2, evaluated at room temperature, was found to range from 16 to 26 mW for animals and man. A new approach to discrimination of the radiation induced signal from the total ESR spectrum of reindeer enamel is proposed. ‘Dose-response’ dependencies of enamel of different species mammals were measured within the dose range from 0.48 up to 10.08 Gy. Estimations of ‘radiosensitivity’ enamel of carnivores and ungulates showed good agreement with radiosensitivity enamel of man by ESR method.     

Analysis of the results of the international comparison of activity measurements of a solution of Fe

The results of an international comparison of activity measurements of a solution of ⁵⁵Fe organized by the BIPM in 2005 are reported and analysed. This exercise, which follows the procedures of the CIPM mutual recognition arrangement to update older comparisons, is a renewal of the comparison organized by the BIPM that took place in 1978. A EUROMET comparison was organized in 1996 specifically to compare activity measurements of a ⁵⁵Fe solution by means of liquid-scintillation techniques. Results of these three comparisons are presented and discussed in this paper.

The radionuclide solution was provided by the NPL, which also distributed the samples to the participants. The activity of the ampoules was measured by 16 laboratories using 12 methods producing 25 results. Some general considerations on uncertainty assessments pertaining to the different techniques used are drawn. The outcome of four different estimators is compared from which the presence of at least one outlier can be confirmed. Further measurements should be made to try to reduce the discrepancy between the results. To date the outcome of the present comparison does not show an improvement to that of the 1996 comparison.     

Evaluation of the results of various technics of non-surgical therapy of varicocele

A new method of non-surgical treatment of varicocele syndrome is described: it consists in sclerotherapy of spermatic vein by trans-femoral percutaneous catheterization with balloon-catheters. In 8 cases venous thrombosis has been induced by direct electric clotting. The techniques and a 6 months follow-up are discussed. It is pointed out that this procedure should be considered as the method of choice for tubular lesions and sub-fertility prophylaxis in young people and in childhood.
