Prevention of Pleural Adhesions Using a Membrane Containing Polyethylene Glycol in Rats

Background: Recurrent thoracotomies regardless of the cause are not a rare occurrence. However, each thoracotomy results in adhesion to some extent. This adhesions increase morbidity and mortality presents a significant inconvenience for surgeons and prolongs the length of operations

Renal and suprarenal insufficiency secondary to familial Mediterranean fever associated with amyloidosis: a case report

<p>Abstract</p> <p>Introduction</p> <p>Familial Mediterranean fever is an autosomal recessive disease that predominantly affects people of the Mediterranean coast. One of the most frequent complications of the disease is amyloidosis. This clinical entity is known as secondary (also called AA) amyloidosis.</p> <p>Case presentation</p> <p>In this report, we describe the case of a 33-year-old Turkish man with familial Mediterranean fever and chronic renal insufficiency. He was admitted to our clinic with symptoms of suprarenal insufficiency. The patient died three months later as a result of cardiac arrest.</p> <p>Conclusion</p> <p>Our aim is to make a contribution to the literature by reporting a case of combined insufficiency due to the accumulation of renal and adrenal amyloid in a patient with familial Mediterranean fever, which has very rarely been described in the literature. We hope that adrenal insufficiency, which becomes fatal if not diagnosed and treated rapidly, will come to mind as easily as chronic renal failure in clinical practice.</p

Effects of retinoic acid on compensatory lung growth

<p>Abstract</p> <p>Background</p> <p>We investigated the effect of Retinoic acid in the growth of contralateral lung after pneumonectomy.</p> <p>Methods</p> <p>Twentyone adult male Wistar albino rats from the same colony were used. They were divided into three groups (Group A, B and C). Group A undergone only left posterolateral thoracotomy. In Group B and C, the rats were subjected to left posterolateral thoracotomy and left pneumonectomy. In Group C, rats were given intraperitoneal Retinoic acid during the operation and continued to be given everyday postoperatively. Rats were sacrificed on the 10^thday and their total body, right lung weights and right lung volumes were measured.</p> <p>Results</p> <p>The volume and weight indices of the lung were found to be higher in Group C. In histopathological examination, there was a reduction in the mean number of alveoli in Group B and C. A significant rise in the mean dimension and average wall thickness of the alveolar structure were determined in Group C.</p> <p>Conclusion</p> <p>Retinoic acid contributes to the compensatory growth of the residual lung tissue.</p

Analysis of the common genetic component of large-vessel vasculitides through a meta- Immunochip strategy

Giant cell arteritis (GCA) and Takayasu's arteritis (TAK) are major forms of large-vessel vasculitis (LVV) that share clinical features. To evaluate their genetic similarities, we analysed Immunochip genotyping data from 1,434 LVV patients and 3,814 unaffected controls. Genetic pleiotropy was also estimated. The HLA region harboured the main disease-specific associations. GCA was mostly associated with class II genes (HLA-DRB1/HLA-DQA1) whereas TAK was mostly associated with class I genes (HLA-B/MICA). Both the statistical significance and effect size of the HLA signals were considerably reduced in the cross-disease meta-analysis in comparison with the analysis of GCA and TAK separately. Consequently, no significant genetic correlation between these two diseases was observed when HLA variants were tested. Outside the HLA region, only one polymorphism located nearby the IL12B gene surpassed the study-wide significance threshold in the meta-analysis of the discovery datasets (rs755374, P?=?7.54E-07; ORGCA?=?1.19, ORTAK?=?1.50). This marker was confirmed as novel GCA risk factor using four additional cohorts (PGCA?=?5.52E-04, ORGCA?=?1.16). Taken together, our results provide evidence of strong genetic differences between GCA and TAK in the HLA. Outside this region, common susceptibility factors were suggested, especially within the IL12B locus

Energy Saving of Conservation Voltage Reduction Based on Load-Voltage Dependency

Reducing voltage to reduce energy consumption, referred to as conservation voltage reduction (CVR), can lead to energy savings. Calculating the effects of reducing voltage requires accurate load models. This paper investigates a load-voltage dependency factor that can be measured via field experiments using common existing instrumentation. A relationship between the load-voltage dependency factor and the percentage of the load that is constant impedance and the percentage that is constant power is presented. A new coordinated control algorithm using the load-voltage dependency factor measured by the field experiments is proposed. Parametric studies are presented which compare CVR with coordinated control versus traditional control. Across the two model comparisons of minimizing energy consumption, the coordinated control for conservation voltage reduction showed significant energy reduction over local control

Chylothorax due to tuberculosis lymphadenopathy: Report of a case

While pulmonary tuberculosis is a very frequent infection, chylothorax is an unusual manifestation of tuberculous disease. A 71-year-old woman with chylothorax is herein presented. The ductus thoracicus was ligated and lymphadenomegaly, which was adjacent to diaphragm, was resected. Based on the findings of various tests, a diagnosis of tuberculosis lymphadenitis was made. The patient was administered antituberculosis chemotherapy and has since remained asymptomatic for 1 year after the operation. In conclusion, tuberculosis lymphadenomegaly may lead to the development of chylothorax. The combination of appropriate surgical and medical treatment is an effective therapeutic strategy for this pathology
