Abstract:
Background: Small bowel perforations are a rare diagnosis compared with esophageal, gastric, and colonic perforations. However, small bowel perforations can be fatal if left untreated. A classification of small bowel perforations or treatment recommendations do not exist to date. Methods: A retrospective, monocentric, code-related data analysis of patients with small bowel perforations was performed for the period of 2010 to 2019. Results: Over a 10-year period, 267 cases of small bowel perforation in 257 patients (50.2% male and 49.8% female; mean age of 60.28 years) were documented. Perforat

The article is aimed at studying the operation of welded I-beams with corrugated web and technological perforations under static loading. The relevance of the study is due to the lack of specific instructions on the pitch, diameter and methods of strengthening technological perforations in the Republic of Kazakhstan and other countries. In this study the method of computer modeling with the help of the program complex LIRA-SAPR-2022 was used.

Abstract:
AbstractTympanic membrane perforation causes a sound conduction disturbance, and the size of this conduction disturbance is proportional to the perforation area. However, precise evaluation of perforation size is difficult, and there are few detailed reports addressing this issue. Furthermore, such evaluation becomes more difficult for irregularly shaped perforations. This study conducted a quantitative evaluation of tympanic membrane perforations, using image analysis equipment.A significant correlation was found between the degree of sound conduction disturbance and the perforation area; thi

Abstract:
For understanding characteristics of Polymethylmetacrylate (PMMA) under impact, the damage behavior of PMMA plates with various thicknesses (1.5 to 6.0 mm) subjected to ballistic impacts with various velocities (63 to 180 m/s) is experimentally investigated using a specialized testing apparatus. Moreover, numerical simulations using the Finite Element Method (FEM) are conducted for the corresponding experimentally studied cases. Ductile response and brittle tensile failure behavior are considered in the FEM to describe the nonlinear response and the failure mode of the PMMA plates. The numeric

Abstract:
Objectives: Management of bladder perforation during TURBT and to evaluate the need for open exploration? Materials and Methods: A retrospective study design was done and 1550 patients underwent TURBT for bladder mass from January 2005 to November 2023. 52 patients were identified with bladder perforation. 20 patients with T2 tumour on biopsy were excluded from final analysis. Parameters recorded on occurrence of a perforation included patient age and sex, tumor stage, grade, multiplicity, size, location, type of bladder perforation and management undertaken. Results: Of a total of 32 patients

Abstract:
Children less than 5 years old are at high risk for foreign body ingestion or aspiration. Therefore, identifying workup and management principles of foreign body ingestion, in the pediatric population, is necessary for pediatric practitioners. Differentiation of caustic ingestion versus benign ingestion is necessary to determine urgency of management. Plain film X ray imaging can be used to differentiate a button battery versus a coin ingestion, based on the halo sign. The urgency of battery ingestion requires immediate medical attention and endoscopic removal, however treatment with honey dur
