Background and Aim: Tuberculous pleural effusion occurs in 30% of patients with tuberculosis (TB). Rapid diagnosis of a tuberculous pleural effusion would greatly facilitate the management of many patients. The purpose of this study was to determine sensitivity, specificity, and predictive values of clinical, laboratory, radiographic findings in patients with tuberculous pleural effusion. Mater...
abstract background: pleural effusion is the accumulation of excess fluid in the pleural cavity. most information available about pleural effusion is obtained from studies on adults and little evidence is available in children. therefore, it is necessary to identify the existing status and explain the disease process, signs, treatment, and prognosis. children with pleural effusion who were admi...
This report presents 29 cases of ocular injury (31 eyes) caused by accidental laser exposure. Twenty-eight eyes were injured during laser adjustment and alignment. Nineteen eyes were damaged by Q-switched lasers at a wavelength of 1064 nm. Macula damage occurred in 25 eyes. During the early phase after injury, there were different degrees of retinal coagulation, edema or hemorrhage in exposed s...
background: pericardial effusion (pe) in down syndrome (ds) patients usually occur s secondary to hypothyroidism, but we have no report of massive pericardial effusion in euthyroid down syndrome patient with supravalvar pulmonary stenosis . case presentation: we report ed an 11-month-old male with down syndrome with massive pericardial effusion that had conservative ...
We develop a contingency theory for how structural closure in a network, defined as the extent to which an actor’s network contacts are connected to one another, affects the initiation and adoption of change in organizations. Using longitudinal survey data supplemented with eight indepth case studies, we analyze 68 organizational change initiatives undertaken in the United Kingdom’s National He...
An increasing number of students, professionals, and job-recruiters are using Social Network Sites (SNSs) for sharing information. There has been limited research assessing the role of individuals seeking a job and receiving information about job openings in SNSs. In this regard, do students, non-managers, and managers benefit from job offers when they are a member of SNSs such as Facebook or L...
Introduction: Pleural effusion may develop during various acute or chronic medical conditions. Despite different diagnostic workups, some cases of pleural effusion may remain undiagnosed. Pleuroscopy and closed biopsy are common diagnostic approaches used for the diagnosis of undiagnosed cases. The present research aimed to evaluate the diagnostic yield of medical pleuroscopy a...
To meet the challenges of increased thermal loads and performance demands on aero-engine turbine blades, more advanced cooling techniques are required. This study used a modification well-known Goldstein equation to predict film effectiveness for an individual hole applied Sellers’ superposition method apply these films across effusion-cooled configurations. In doing so, it tackles relatively u...
Direct numerical simulations are used to investigate the method of effusion cooling in a laminar Mach-2.67 boundary layer. Air is employed as mean-flow and coolant gas and is introduced into the boundary layer through two staggered or aligned rows of holes by means of a modeled blowing approach. First, the effects of streamwise inclined blowing with various inclination angles αc are investigate...
background: fracture load of implant-supported restorations is an important factor in clinical success. this study evaluated the effect of two techniques for screw access hole preparation on the fracture load of cement-screw retained implant-supported zirconia-based crowns. methods: thirty similar cement-screw retained implant-supported zirconia-based maxillary central incisor crowns were evalu...
