The microfloral characteristics of the atmosphere and of the human respiratory tract during the performance of drilling operations]

Some changing in microflora of the bore works are noted. It expressed in increasing of staphylococci index.     

Isolated corrected transpostion of great vessels]

Isolated corrected transposition of the major vessels is a rare congenital pathology that may have an asymptomatic course. In some cases the patients develop some symptoms of cardiac pathology due to the disorders in the atrioventricular conductivity and the development of "mitral" insufficiency. The disturbances in the atrioventricular conductivity and in the cardiac rhythm may be provoked in such patients by intercurrent diseases due to intoxication, and the development of "mitral" insufficiency is brought about by the peculiarities of the structure of the arterial morphologically right ventricle working under functional tension. The diagnosis of an isolated corrected transposition of the major vessels is based on the data of electrocardiography and X-ray. The final diagnosis is made after heart catheterization and angiocardiography.     

A hollow bougie and its use for therapeutic and diagnostic purposes in esophageal stenosis of unclear etiology

The results of treatment of patients with stenosis of the esophagus of unrecognized genesis are discussed. The traditional method of diagnosis, radiological and endoscopic with target biopsy, produced diverse results. The authors describe a method for bougienage of the esophagus by means of an original bougie with which dilatation of the stenosed segment can be combined with collection of bioptic material from the stenosed part and its lower pole. This made it possible to verify the diagnosis and determine the subsequent therapeutic tactics.     

β地贫CD41-42突变杂合子复合缺失型α地贫双重杂合子的基因检测与血液学分析

目的了解β地中海贫血(地贫)CD41-42(-TCTT)杂合子(β41-42杂合子)复合缺失型α地贫双重杂合子在本地区β41-42杂合子个体中的检出情况及其临床血液学表现.方法分别采用单管多重PCR与反向点杂交法检测缺失型α地贫与β地贫基因,常规进行血细胞分析及其它地贫筛查试验.结果 144例β41-42杂合子有8例同时复合缺失型α地贫杂合子,其中7例(4.9%)携带有α地贫1基因(αα/--SEA),1例(0.69%)携带有缺失型HbH基因(-α3.7/--SEA).7例复合α地贫1患者的MCV均都高于另外136例单纯的β41-42杂合子的MCV平均值(63.53fl); 而对携带有HbH基因的样本进行pH8.6与6.5的血红蛋白电泳时都无法找到HbH区带.结论诊断β41-42杂合子复合α地贫双重杂合子的患者时,如只依赖其临床表现和常规的实验室检查结果作为筛查诊断的指标,容易会出现有病患的α或β地贫基因漏诊的情况.     

Successful endovascular treatment for orbital varix: case report and literature review

The pathogenesis and clinical manifestations of orbital varix and choice of its surgical treatment are described. Complete occlusion of abnormal portions of the superior ophthalmic vein with preserved blood flow along the main trunk is a specific feature of this observation. By analyzing the data available in the literature and their clinical observation of successful endovascular treatment for orbital varix with a complete regression of its clinical symptoms, the authors substantiate indications for transvenous orbital varix occlusion.     

A nutrient medium for the isolation of staphylococci with persistence characteristics]

A new selective medium with fusidine for isolation of persistent staphylococci is developed and tried. The medium can be used for detecting the agent (staphylococcus) in mixed microflora in infectious diseases, in screenings for resident Staphylococcus carriership, in bioindication of air contamination, for predicting the course and for monitoring rational therapy of pyoinflammatory diseases in humans and animals in medicine and veterinary.
