NRF2, KEAP1 and GSK-3 levels in autism spectrum disorder: a case control study.

Recent studies show that oxidative stress has an important role in the etiology of autism. In our study, Nrf2, which is the main regulator of cellular antioxidant response, and Keap1 and Gsk-3β, which are the main proteins that regulate this pathway, were compared between children with autism and healthy controls. To the best of our knowledge, our study is the first in which Nrf2, Keap1 and Gsk-3β levels were evaluated together in children with ASD.

INTERBLEED: Design of an International Study of Risk Factors for Gastrointestinal Bleeding and Cardiovascular Events After Gastrointestinal Bleeding.

Background: Bleeding is the most common adverse event in those with cardiovascular (CV) disease receiving antithrombotic therapy, and it most commonly occurs in the gastrointestinal (GI) tract. Clinicians often dismiss bleeding as an adverse event that is reversible with effective antithrombotic therapy, but bleeding is associated with substantial morbidity and mortality, most likely mediated through an increased risk of CV events. Reducing the burden of bleeding requires knowledge of the potentially modifiable risk factors for bleeding and the potentially modifiable risk factors for adverse outcomes after bleeding.

Ruxolitinib treatment in an infant with JAK2+ polycythaemia vera-associated Budd-Chiari syndrome.

Budd-Chiari syndrome (BCS) is caused by hepatic venous outflow obstruction commonly seen with myeloproliferative neoplasms (MPNs). Polycythaemia vera (PV) is a very rare MPN in childhood. This is the youngest reported patient diagnosed with PV and BCS secondary to mutation.

A rare case of non-traumatic acute intraabdominal hemorrhage: ruptured superior mesenteric artery aneurysm.

Introduction: Rupture of superior mesenteric artery aneurysm (SMAA) is a very rare and life-threatening condition, presenting with acute intraabdominal hemorrhage.

Case: The patient was hospitalized upon complaint of nonspecific severe abdominal pain. Diagnosis of SMAA was established by abdominal Doppler ultrasound that showed a pseudo-aneurysmal lesion with size of 76 × 47 mm at the superior mesenteric main branch.

An infant with prolonged circumcision bleeding and unexplained coagulopathy.

Tyrosinemia type I is a rare autosomal recessive disorder. Fulminant onset of liver failure can occur in the first few months of life. Because all of the clotting factors are produced exclusively in the liver except factor VIII, coagulation abnormalities are very common in patients with severe liver disease.

Intramedullary nailing and angulation prevention in distal metaphyseal tibial fractures.

Intramedullary nailing, which is preferred in tibial diaphyseal fractures, is also frequently used in distal third tibial fractures. Various angular deformities, including varus/valgus deformity, may be observed during postintramedullary nailing. Orthopedic surgeons use several methods to prevent this problem.

[Two cases of rare cerebral hydatid cyst].

Hydatid cyst disease (Echinococcosis) is a parasitic illness that is rarely located in the brain. Primary cerebral hydatid cyst disease is rarely seen. We report here rare two cases presenting with sixth cranial nerve palsy with increased intracranial pressure syndrome due to primary cerebral hydatid cyst.

[Comparison of disc diffusion, E-test, and broth microdilution methods for the determination of resistance to colistin, polymyxin B, and tigecycline in multi-resistant Acinetobacter baumannii isolates].

The increased rate of antimicrobial resistance in Acinetobacter baumannii made it necessary to reconsider old antibiotics such as polymyxins and develop new drugs such as tigecycline. The aim of this study was to investigate the susceptibility rates of multi-drug resistant A. baumannii clinical isolates to colistin, polymyxin B, and tigecycline by three different methods in microbiology laboratory of Gaziantep University Research Hospital, between September 2006 and April 2008.

[Evaluation of the patients with low levels of anti-HCV positivity].

Laboratory diagnosis of hepatitis C virus (HCV) infection is based on the detection of anti-HCV antibodies by enzyme immunoassay (EIA) or chemiluminescence immunoassay (CIA) techniques. However, a consensus related to the problem of low titer (Serum/Cut-off; S/C= 1.0) anti-HCV antibodies is still lacking.

[Enterococcus spp. colonized in the gastrointestinal tract of patients in hemato-oncology and intensive care units and their resistance profiles to vancomycin].

The aim of this study was to identify the Enterococcus spp. and to determine their vancomycin-resistance profiles, in the samples collected from the patients who were described as risky groups for vancomycin-resistant enterococcal (VRE) colonization, in scope of a survey study carried out in our hospital for the first time. Rectal swab samples were taken once in a month from a total of 180 patients who were hospitalized in the Surgery and Intensive Care Units, adult Oncology-Hematology and Pediatric Oncology Units between March-December 2006.

[Investigation of the frequency of extended spectrum beta-lactamases and antibiotic resistance in clinical isolates of Escherichia coli and Klebsiella sp].

The aim of this study was to detect the presence of extended spectrum beta-lactamase (ESBL) in clinical isolates of Escherichia coil and Klebsiella sp. and to determine in vitro antibiotic resistance of these strains. A total of 78 E.

[Evaluation of the knowledge and attitude of obstetric patients on epidural analgesia].

Epidural analgesia (EA) is one of the most commonly used techniques in obstetric analgesia. Our objective was to evaluate patients who experienced EA during labour as well as to find out their knowledge, attitude and behaviour in this matter, prospectively. Between 1997 and 2002, a questionnaire, "patient evaluation form for EA", was delivered to 190 obstetric patients.

[Evaluation of the methods used for the serologic diagnosis of brucellosis].

Serological tests are the most widely used methods for the diagnosis of Brucella infections, since bacterial isolation techniques are time consuming. The conventional serological methods are the tube and slide agglutination tests, however enzyme immunoassays (ELISA) have gained importance recently as rapid diagnostic techniques. The aim of this study was to evaluate the performances of standard tube agglutination (STA, Wright test), slide agglutination (Rose-Bengal, RB) and ELISA-IgG and -IgM methods, in the serological diagnosis of brucellosis.

[Reconstruction with vein graft interposition and pedicled muscle flap in a patient with above.elbow partial arm amputation].

It is difficult to decide replantation or revascularization in partial or total amputations proximal to the wrist. Important point is the expected functional result and/ or protection of sensibility. Crush type partial or total amputations have poor prognosis.

[Hemothorax and retroperitoneal bleeding caused by warfarin use in a polytraumatized patient].

If some medical problems are not noticed to in polytraumatized patients at the right time, they may be caused by serious complications. The haematological parameters, especially bleeding and coagulation factors, are very important for them. If they use warfarin, heparin or salicylates, they should be cared intensively.

Diagnostic value of biochemical markers of bone turnover and postmenopausal osteoporosis.

We studied 77 women divided into postmenopausal osteoporotic and premenopausal and postmenopausal non-osteoporotic groups in order to evaluate bone metabolism and diagnostic value of biochemical markers of bone turnover in postmenopausal osteoporosis. Postmenopausal osteoporotic (n: 40), postmenopausal non-osteoporotic (n: 24) and premenopausal non-osteoporotic (n: 13) groups were defined according to bone mineral density (BMD) scores obtained with dual energy X-ray absorptiometry (DEXA). Urinary deoxy-pyridinoline (Dpd), pyridinoline (Pyd), serum total alkaline phosphatase (ALP), bone specific alkaline phosphatase (BALP), osteocalcin (BGP), total calcium, phosphorus, and creatinine levels were determined.
