Case Presentation: A 54-year-old male patient presenting probable multiple system atrophy with predominant parkinsonism who underwent bilateral deep brain stimulation (DBS) of the pedunculopontine nucleus (PPN) is presented. The patient had dominant freezing of gait (FOG), levodopa-resistant bradykinesia, and autonomic disturbances, but with a good cognitive condition.
Methods: The patient underwent bilateral DBS of the PPN, which ended with modest benefits.
Objectives: This retrospective study was designed to investigate the role of fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) in determination of recurrence and/or intraabdominal metastasis in patients with ovarian cancer having increased tumor markers or suspicious lesion detected by a contrast-enhanced abdominal CT (ceCT).
Materials And Methods: A total of 34 female patients who were treated for histopathologically proven ovarian cancer, underwent PET/CT examination for restaging and suspected recurrence. Patients with pathology report, tumor marker levels, ceCT and PET/CT performed within one month were included in the study.
Gender, age adjusted, population based reference ranges are necessary to use insulin-like growth factor 1 (IGF-1) as a diagnostic marker or for therapeutic monitoring in growth hormone (GH) related diseases. The aim of the present study was to describe the serum IGF-1 distribution and to calculate age and gender specific reference values for Caucasian adult population. A representative sample of 1002 male and 1039 female, totally 2041 participants aged above 18 years old was examined.

We investigate alterations during the three phases of requirements for intraoperative isoflurane within the target of 40 to 55 Bispectral Index (BIS) values concerning patients with end-stage liver disease who are undergoing liver transplantation. After faculty ethics committee approval, we studied 50 patients of (age range, 18 to 65 years) who were undergoing liver transplantation.

Metabolic syndrome (MetS) is also characterized by inflammation, In this study, we hypothesised that the prevalence of MetS would increase in patients with asthma. Based on this, we evaluated the prevalence of MetS in patients with asthma and the relationship between asthma and cardiometabolic risk factors.

By performing surface doping dependence measurements as a function of photon polarization and sample orientation we show that second harmonic generation can simultaneously probe both the surface crystalline structure and the surface charge of Bi(2)Se(3). Furthermore, we find that second harmonic generation using circularly polarized photons reveals the time-reversal symmetry properties of the system and is surprisingly robust against surface charging, which makes it a promising tool for spectroscopic studies of topological surfaces and buried interfaces.

Background: The aim of this study was to retrospectively evaluate our approach to the diagnosis and treatment of penile fracture.
Methods: We retrospectively evaluated the results of 107 patients with penile fracture treated in our clinic between January 1990 and January 2009. Patient age, etiology of each fracture, history, physical examination results, radiologic findings, type of treatment, and postoperative complications were recorded.

Purpose: The most significant application of polychlorinated biphenyls (PCBs) is in transformers and capacitors. Therefore, power plants are important suspected sources for entry of PCBs into the environment. In this context, the levels and distribution of PCBs in sediment, soil, ash, and sludge samples were investigated around Seyitömer thermal power plant, Kütahya, Turkey.

A primary goal in organ transplant is the prevention or effective treatment of infection, which is the most common life-threatening complication of long-term immunosuppressive therapy. A 21-year-old woman who underwent heart transplant 3 years previous owing to dilated cardiomyopathy was referred to our hospital with symptoms of high fever and cough.

In this in vitro study, we investigated whether different heparin concentrations can affect the cell cycle of lymphoblasts in newly diagnosed acute lymphoblastic leukemia (ALL) patients.
Methods: Lymphoblasts were incubated in different heparin concentrations (0, 10, 20 U/ml), and the percentages of lymphoblasts in each phase of the cell cycle were simultaneously measured by flow cytometry at 0, 1, and 2 hours (h).
The spatial distribution, degree of pollution and major sources of PCBs were evaluated in surficial sediments within the heavily urbanized and industrialized İzmit Bay and its main freshwater inputs. ΣPCB concentrations range from 2.90 to 85.

Objective: Treatment of perianal abscesses requires prompt surgical drainage and antimicrobial therapy. However, we should encourage the selective use of antimicrobial agents on a case-by-case basis, especially because there is no evidence that uncomplicated perianal abscesses can be safely treated only with drainage. For this reason, it is important to identify the causative organisms; therefore, we accessed the microbiological analysis of these patients.

We reviewed cytogenetic studies performed on 4216 patients who were referred to the Cytogenetics Unit at Dicle University Hospital, Diyarbair, Southeast Turkey, between 2000 and 2009. The cases were grouped according to the reason of referral for cytogenetic analysis. The frequencies of the different types of numerical and structural abnormalities were determined, and the relative frequency of cases with abnormal karyotypes was calculated in each group.
