Atypical variants of the acute appendicitis course occur in 20-30% of patients. Indistinctive clinical picture is explained by the location variety of the vermiform appendix in the abdomen. The paper presents the peculiarities of clinical manifestations of acute appendicitis. Particular attention is given to the atypical clinical signs depending on the localization of the vermiform appendix in the abdominal cavity. Posibilities of diagnostic visualization methods (ultrasound, multislice computed tomography) for the differential diagnosis of the "acute abdomen" syndrome are under discussion, as well as the reasons of possible misdiagnosis. This case report demonstrates one of the multiple "masks" of acute appendicitis - the "chameleon of the abdominal cavity" and the difficulties of clinical diagnosis in case of mesoceliac appendix. Atypical onset of the disease, which the patient associated with a large meal, intolerable pains, frequen vomiting, not typical for acute appendicitis forced position, physical findings served as a basis for working diagnosis - acute intestinal obstruction. This version of small bowel invagination was supported by means of diagnostic visualization. The erroneous conclusion was obviously associated with the location of the vermiform appendix, its size (D=1,2 cm) and severe inflammatory changes. Videolaparoscopy turned out to be a comprehensive method of diagnosis and treatment.

Ticks and Tick-borne Diseases | Year: 2017

Tick-borne encephalitis virus is the etiological agent of a severe human disease transmitted by hard ticks. It occurs in large parts of eastern, central, and western Asia and in Europe with thousands of human cases each year. Here, the discovery of the virus by Soviet scientists in the late 1930s in the Far East is described. The pioneering work involved with this discovery, which resulted in great scientific and epidemiological achievement, was undertaken under the most difficult conditions, and some of the scientists and their technical assistants paid for it with their health and even their lives. This paper briefly outlines the steps on the way that elucidated the basic etiology and eco-epidemiology of the disease, and does not omit that, as one result of the expeditions and the political situation in the former Soviet Union at that time, some scientists were sent to prison. © 2017.

The results of an experimental study of the laser radiation effect on the crystal's formation in the volume of biological fluids that are complex multi-component solutions have been discussing. Are investigated white and natural bile in vitro. The qualitative changes were observed. Thus, at the bottom of the cell in which bile is not exposed to the laser radiation, the crystals are formed. In the irradiated bile gallstone has a thin layer of a homogeneous viscous colloidal liquid with very small, visible in polarized light crystalline formations was got. Irradiated laser bile's gallstone was covered evenly white deposit without surface defect unlike gallstone in bile without radiation exposure. A possible mechanism to explain the laser radiation action on the mineral formation in biological fluids and also practical application of this effect have been suggesting too. © 2016 SPIE.

An interaction of different human alleles and endemic bacterial strains may be clinically manifested as different outcome of the disease in different hosts infected with the same genotype. The primary objective of this study was to investigate this issue in the model of Mycobacterium tuberculosis and human DC-SIGN encoding CD209 promoter SNP (rs4804803) in Russian Siberian population. We sought to find a possible combination of M. tuberculosis lineage and human host allele/genotype correlating with unfavorable outcome of the disease. The 101 paired DNA samples from patients with pulmonary TB (human and M. tuberculosis DNA) were studied by 12-loci MIRU-VNTR typing (M. tuberculosis strains) and CD209 -336 A/G typing (human DNA). Ninety autopsy DNA samples as a source of human and mycobacterial nucleic acids from persons who died from TB were also subjected to the same genotyping procedures. A human control group consisted of 177 healthy individuals. The Beijing genotype was more frequently identified in autopsy versus patient samples, in 70.0% and 51.5%, respectively (χ 2=6.06, P=0.01). Regarding other M. tuberculosis genetic families, no significant difference in LAM family distribution among patient strains and autopsy samples has been found. In contrast, Ural genotype was significantly less frequently detected in the autopsy samples (χ 2=6.12, P=0.01). Allelic and genotypic frequencies of the CD209 -336A/G did not differ significantly under global comparison when contrasting controls versus patients versus autopsy samples. However intriguing and contrasting significant associations were found in the male subgroup under M. tuberculosis genotype-stratified comparisons. Firstly, male carriers of -336AA genotype were more frequently infected with Beijing genotype (χ 2=5.2, P=0.02). Secondly and remarkably, this association was inverted in the autopsy sample: male carriers of -336AA genotype died less frequently due to TB caused by a Beijing rather than a non-Beijing strain (χ 2=5.37, P=0.02). In conclusion, we hypothesize that although carriers of CD209 -336A allele are more sensitive to infection with a Beijing strain, a combination of human CD209 -336G allele and M. tuberculosis Beijing genotype leads more frequently to the lethal outcome in pulmonary TB male patients in Russian (Caucasian) population. © 2011 Elsevier B.V..

Purpose: The aim of this study was the comparison of single-port and multiport laparoscopic methods for the treatment of inguinal hernia in children during the first 3 months of life. Subjects and Methods: Between January 2002 and December 2012, we performed 260 laparoscopic operations in neonates and infants with the diagnosis of inguinal hernia. Surgical procedures were single-port endoscopic herniorraphy (Group I; 180 patients) and multiport laparoscopic herniorraphy (Group II; 80 patients). The two groups were compared for demographics of patients, operative report, and early and late postoperative outcomes. Results: We applied the single-port laparoscopic method for correction of inguinal hernia in small babies. The mean operative time (duration of one-sided and bilateral repair) in Group I was 16 minutes, whereas the mean duration of the operation in Group II was 15.73 minutes. The number of doses of postoperative analgesia was 1.19 and 1.22, respectively. The length of hospital stay was 8.12 hours in Group I and 8.27 hours in Group II. No differences between the two groups were recorded in the follow-up period: no recurrence in either group and hydrocele formation in only 1 patient in Group II. Conclusions: There are similar functional results in treatment of inguinal hernia in babies during the first 3 months of the life using single- and multiport laparoscopy. Scarless cosmetic results are seen in the single-incision laparoscopic surgery group. © Copyright 2015, Mary Ann Liebert, Inc. 2015.

Purpose: Thoracoscopic plication of the diaphragm is an alternative to conventional surgical treatment of diaphragmatic evisceration via thoracotomy in neonates and infants. The aim of this study is to compare results of treatment by these two methods in the past 11 years. Materials and Methods: We studied the data of 35 neonates who underwent standard posterolateral thoracotomy (18 patients; Group I) or video-assisted thoracoscopic surgery (17 patients; Group II) for diaphragmatic plication. The two groups were compared for patient demographics, operative reports, and postoperative parameters. Results: The groups were similar in terms of demographics and preoperative parameters. There was a significant difference in mean operative time between the open and thoracoscopic procedure (71.67 minutes versus 51.76 minutes; P<.05). Duration of care in the neonatal intensive unit and length of hospital stay were significantly shorter in Group II (5.89 days versus 3.23 days [P<.05] and 13.06 days versus 9.88 days [P<.05]). Early postoperative complications (hemothorax, pneumothorax) were frequent in the thoracotomy group (Group I) (16.67% versus 0%; P>.05). Recurrence of diaphragmatic evisceration was observed only in the thoracotomy group (11.11% versus 0%; P=.486). Conclusions: Thoracoscopic plication of the diaphragm in infants in the first 3 months of life demonstrates better results than open surgery. © Mary Ann Liebert, Inc. 2015.

Using the equations of scalar diffraction theory we consider the formation of an optical vortex on a diffractive optical element. The algorithms are proposed for simulating the processes of propagation of spiral wavefronts in free space and their reflections from surfaces with different roughness parameters. The given approach is illustrated by the results of numerical simulations. © 2013 Kvantovaya Elektronika and Turpion Ltd.
