Aim: To study the efficiency of reconstructive operations in “recent” iatrogenic injuries of extrahepatic biliary tracts. Methods. The experiment on surgical treatable of 22 patients with iatrogenic “recent” injuries of extrahepatic biliary tracts is submitted. Primary reparative operation has been performed to 1 patient (suturing of hepaticocholedochus injury after Laparoscopic cholecystectomy). Reparative operations throughout Roux-en-Y biliodigestive anastomosis were performed to 19 patients (Roux-en-Y hepaticojejunostomy - 4, Roux-en-Y bihepaticojejunostomy - 13, Roux-en-Y trihepaticojejunostomy - 2). The external drainage of extrahepatic biliary tracts of the 2nd patient has been the final method of surgical treatable. Results.Post-surgery complaints and mortalities. Among all the 22 patients with iatrogenic injuries of extrahepatic biliary tracts the post-surgery complaints of 4 patients have been registered: failure of stitches of Roux-en-Y bihepaticojejunostomy - 1, acute adhesive small bowel obstruction - 1, stenosis of bihepaticojejunostomy - 1, purulence of surgical wound - 1. Post-surgery mortality is 4,5 %. Conclusion.Roux-en-Y biliodigestive surgery is the main conclusive method in reconstructive treatment of iatrogenic injuries of extrahepatic biliary tracts.

Purpose: to develop the optimal (safe and effective) method of diamond burr polishing of Bowman’s membrane (DBPBM) for the possible use it in the treatment of the recurrent corneal erosion syndrome (RCES) in the experiment.Material and methods. DBPBM in different modifications of the  method and the mechanical deepithelization were performed in  experiment on 19 human cadaver eyes. We use system Ophtho-Burr  for DBPBM that includes a tip and ophthalmic burrs with diameter  1mm, 2.5 mm, 5 mm, varying the speed of rotation of burr. For 3  eyes — polishing with the application of burr with a diameter of 5  mm, the rotation frequency of 4000 rpm using 2 passes over the  surface of the cornea. For 3 eyes — burr with a diameter of 2.5 mm,  rotation frequency of 4000 rpm in 2 perpendicular passes. For 3 eyes — diameter burr 1 mm at speed of 8000 rpm in 2 perpendicular  passes. For 3 eyes — diameter burr 1 mm at speed 4000 rpm with 4  passes along the surface of the cornea. For 4 eyes — diameter was 1 mm at speed of 4000 rpm in 2 perpendicular passes. For 3 the eyes  was conducted mechanical deepithelization. Subsequent histopathological investigation of the cornea was  performed by method of semi-thin section, with polychrome staining.Results. The obtained results of histological studies of DBPBM in  different versions on cadaver cornea is allowed to choose the optimal variant of surgical intervention for use in clinical conditions. It  consisted in a selection of burr with a diameter of 1 mm, the rotation frequency of the 4000 rpm and 2 perpendicular passes with a  moderate compression of the cornea. The abovementioned technique of intervention allows removing completely the corneal epithelium  with a basal membrane and save uniform in thickness, fully  deepitelizationed Bowman’s membrane.Conclusion.Careful and accurate removal of dysplastic corneal epithelium in cases of the recurrent corneal erosion syndrome using  proposed method in clinical conditions should contribute to the  creation optimal environments for adequate reepithelization with  steady epithelial-stromal adhesion. The remaining nearly intact  Bowman’s membrane after procedure can prevent some postoperative complications such as haze and induced refractive disorders.

A clinical case of surgical management of patient with biliodigestive anastomosis stricture complicated by multiple intrahepatic lithiasis is presented. The patient was 57 years old woman. Anamnesis of the disease: in 2016, biliodigestive anastomosis was performed due to iatrogenic damage of the biliary tract. She was admitted to the hospital with complaints of the right upper abdomen pain, accompanied by chills, jaundice, and fever up to 39°C. The examination revealed a stricture of a previously formed biliodigestive anastomosis complicated by multiple intrahepatic cholelithiasis. Surgical intervention was performed: at the first stage – percutaneous transhepatic cholangiostomy; at the second stage – laparotomy, separation of hepaticojejunoanastomosis, intraoperative cholangioscopy with lithoextraction, resection of a small bowel section with a Brownian anastomosis, post-colon hepaticojejunostomy on a disconnected loop and replaceable transhepatic drains (Smith-Praden-Saypol-Kurian).

Clinical Conditions

Pseudohyponatremia is a clinical condition characterized by an increased fraction of protein or lipid in plasma, thereby resulting in an artificially low plasma sodium concentration ([Na+]p). Since the automated method of measuring [Na+]pin most laboratories involves the use of an indirect ion-selective electrode (I-ISE), this method does not correct for elevated protein or lipid concentrations. In I-ISE, the plasma sample is diluted before the actual measurement is obtained, and the [Na+]pis determined based on the assumption that plasma is normally composed of 93% plasma water. Therefore, the [Na+]pas determined by I-ISE will be artificially low in clinical conditions when the plasma water content (PWC) is <93%. In contrast, the plasma is not diluted when the [Na+]pis measured using direct ISE (D-ISE). This method directly measures Na+activity in plasma water and is therefore unaffected by the proportion of plasma occupied by water. In this study, we report a novel quantitative method for determining the PWC utilizing I-ISE and D-ISE. To validate this new method experimentally, we altered the PWC in vitro by dissolving varying amount of salt-free albumin in human plasma. We then measured PWC gravimetrically in each sample and compared the gravimetrically determined PWC with the ISE-determined PWC. Our findings indicate that the PWC can be accurately determined based on differences in the [Na+]pas measured by I-ISE and D-ISE and that this new quantitative method can be a useful adjunct in the analysis of the dysnatremias.

Abstract Background The biological network is highly dynamic. Functional relations between genes can be activated or deactivated depending on the biological conditions. On the genome-scale network, subnetworks that gain or lose local expression consistency may shed light on the regulatory mechanisms related to the changing biological conditions, such as disease status or tissue developmental stages. Results In this study, we develop a new method to select genes and modules on the existing biological network, in which local expression consistency changes significantly between clinical conditions. The method is called DNLC: Differential Network Local Consistency. In simulations, our algorithm detected artificially created local consistency changes effectively. We applied the method on two publicly available datasets, and the method detected novel genes and network modules that were biologically plausible. Conclusions The new method is effective in finding modules in which the gene expression consistency change between clinical conditions. It is a useful tool that complements traditional differential expression analyses to make discoveries from gene expression data.

Set of instruments and metal fixatives for osteosynthesis in corrective operations on proximal femur in patients aged 1-15 years was elaborated at CITO. Comparative experimental strength tests showed the advantages of suggested metallic fixatives over existed analogs (fixatives from DON set and Blount plate). Cannulated system for angular metal fixatives application provided for proper setting of the construction, shortened the duration of surgical intervention and decreased operative trauma. That set was used for the treatment of 169 children with various types of hip joint pathology. Average duration of surgical intervention made up 45 min. (versus 95 min. at routine surgical technique). Bone fragments displacement, loss of correction, instabi-lity of osteosynthesis and other complications were not observed at follow up less than 1 year.

This paper reports two clinical cases of ACTH-dependent hypercorticism. Difficulties encountered in differential diagnosis of this condition were due to poor informative value of routine diagnostic methods. The use of selective blood collection from the inferior petrosal sinuses (for the first time in Russia) greatly facilitated the choice of the adequate treatment strategy. A detailed description of clinical features of ACTH-dependent hypercorticism in two young women is presented along with the results of laboratory and instrumental studies. Technical aspects of selective blood collection from the inferior petrosal sinuses in conjunction with the desmopressin stimulation protocol are considered. Indications for the use of this diagnostic method under real clinical conditions are proposed. Results of the study are discussed with reference to the treatment strategy chosen for the management of ACTH-dependent hypercorticism and the outcome of surgical intervention.

Background and objectives: Brain ischemic stroke is caused by impaired or absolutely blocked blood flow into the brain regions. Despite the large number of possible origins, there is no general strategy for preventive treatment. In this paper, we aimed to predict the hemodynamics in a patient who experienced a critical stenosis operation in the carotid artery. This is a unique study where we used medical data together with the computational fluid (CFD) technique not to plan the surgery, but to predict its outcome. Materials and Methods: AngioCT data and blood perfusion of brain tissue (CT-perfusion) together with CFD technique were applied for stroke formation reconstruction in different clinical conditions. With the use of self-made semiautomatic algorithm for image processing and 3DDoctror software, 3D-vascular geometries before and after surgical intervention were reconstructed. As the paper is focused on the analysis of stroke appearance, apparent stroke was simulated as higher and lower pressure values in the cranial part due to different outcomes of the surgical intervention. This allowed to investigate the influence of spatial configuration and pressure values on blood perfusion in the analyzed circulatory system. Results: Application of CFD simulations for blood flow reconstruction for clinical conditions in the circulatory system accomplished on average 98.5% and 98.7% accuracy for CFD results compared to US-Doppler before and after surgical intervention, respectively. Meanwhile, CFD results compared to CT-perfusion indicated an average 89.7% and 92.8% accuracy before and after surgical intervention, respectively. Thus, the CFD is a reliable approach for predicting the patient hemodynamics, as it was confirmed by postoperative data. Conclusions: Our study indicated that the application of CFD simulations for blood flow reconstruction for clinical conditions in circulatory system reached 98% and 90% accuracy for US-Doppler and CT-perfusion, respectively. Therefore, the proposed method might be used as a tool for reconstruction of specific patients’ hemodynamics after operation of critical stenosis in the carotid artery. However, further studies are necessary to confirm its usefulness in clinical practice.
