Objective: The aim of this study was to examine the distribution of olfactory filaments (OFs) in the nasal mucosa to facilitate preservation of olfactory function in endonasal approaches and preparation of a nasoseptal flap.

Methods: One formalin-fixed and 9 fresh cadaveric silicone-injected specimens with 20 total sides were studied to measure the distance of the OFs to the anatomical landmarks and compare the OF presence in the nasal septum mucosa (NSM) and ethmoidal mucosa (EM).

Results: The mean distance from the first to the last OF was 19.

Purpose: The total number of older adults in Turkey is striking, amounting to around 8 million, and this translates into considerably higher numbers of cases of osteoporosis (OP) and fractures in older adults. In this article, we outlined the current situation of OP in older adults in Turkey and investigated the differences between Turkey and a representative developed European country (Belgium), in terms of the screening, diagnosis, and treatment of OP. Our intention in this regard was to identify areas in need of improvement and subsequently to make a clear call for action to address these issues.

Several prominent theories of schizophrenia suggest that structural white matter pathologies may follow a developmental, maturational, and/or degenerative process. However, a lack of lifespan studies has precluded verification of these theories. Here, we analyze the largest sample of carefully harmonized diffusion MRI data to comprehensively characterize age-related white matter trajectories, as measured by fractional anisotropy (FA), across the course of schizophrenia.

Rett syndrome is rarely suspected in males because of the X-linked dominant inheritance. In the literature, only six male patients have been reported with methyl-CpG-binding protein 2 (MECP2) mosaicism. Next-generation sequencing (NGS) methods have enabled better detection of somatic mosaicism compared to conventional Sanger sequencing; however, mosaics can still be difficult to detect.

Relation of RANKL and OPG Levels with Bone Resorption in Patients with Acromegaly and Prolactinoma.

Horm Metab Res

July 2018

Hacettepe Medical School, Department of Endocrinology and Metabolism, Hacettepe University, Ankara, Turkey.

The objective of this study was to investigate the effect of hyperprolactinemia and high levels of insulin-like growth factor-I (IGF-I) on bone resorption and their relation with receptor activator of nuclear factor-κB ligand (RANKL) and osteoprotegerin (OPG) in patients with prolactinoma and acromegaly. Thirty-one patients with acromegaly, 28 patients with prolactinoma, and 33 healthy individuals were included in the study. Serum concentrations of RANKL, OPG, bone alkaline phosphatase (bone ALP), osteocalcin (OC), C-terminal telopeptide of type 1 collagen (CTX), procollagen type 1 N-terminal propeptide (P1NP) and urine deoxypyridinoline (DPD) levels were detected and bone mineral density (BMD) was measured.

Adipocytokines and aging: adiponectin and leptin.

Minerva Endocrinol

June 2013

Department of Endocrinology and Metabolism, Hacettepe Medical School, Ankara, Turkey.

Adipose tissue is an active metabolic organ secreting adipocytokines which are involved in the energy homeostasis and regulation of glucose and lipid metabolism. Aging is associated with fat redistribution, which is characterized by loss of peripheral subcutaneous fat and accumulation of visceral fat. Visceral adipose tissue is more involved in the developement of metabolic diseases than subcutaneous adipose tissue.

Adipocyte differentiation defect in mesenchymal stromal cells of patients with malignant infantile osteopetrosis.

Cytotherapy

September 2009

Department of Pediatrics, Division of Hematology-Bone Marrow Transplantation Unit, University of Hacettepe Medical School, Ankara, Turkey.

Background: Malignant infantile osteopetrosis (MIOP) is a disorder of osteoclasts characterized by defective bone resorption and death in infancy. The multipotent mesenchymal stromal cells (MSC) and their progeny (osteoblasts) are major components of the bone marrow (BM) microenvironment and are found in close contact with cells of hematopoietic origin, including osteoclasts. We hypothesized that MSC defects may be associated with osteoclast dysfunction and osteopetrosis phenotype.

McCune-Albright syndrome associated with acromegaly and bipolar affective disorder.

Eur J Intern Med

December 2007

Hacettepe University, Hacettepe Medical School, Department of Nuclear Medicine, 06100-Sihhiye, Ankara, Turkey.

McCune-Albright syndrome is a rare disorder caused by an activating mutation in the gene (GNAS1) encoding the subunit of the G protein. This syndrome is characterized by polyostotic fibrous dysplasia, café-au-lait pigmentation, and multiple endocrine hyperfunction. A 29-year-old male with polyostotic fibrous dysplasia, café-au-lait pigmentations, and pituitary adenoma is presented in this report.

Kaposi's sarcoma (KS) is an unusual tumor principally affecting the skin of the lower extremities. Although the association between KS and renal transplant has been well documented, there are a few KS cases in the literature associated with membranoproliferative glomerulonephritis or other glomerular diseases. This report presents a patient with membranoproliferative glomerulonephritis (MPGN) who developed KS following treatment with long-term medium dose glucocorticoid and short-term additional immunosuppressives.

The purpose of the study was to evaluate the efficacy of percutaneous drainage of intraperitoneal abscesses with attention to recurrence and failure rates. A retrospective analysis of percutaneous treatment of 300 intraperitoneal abscesses in 255 patients (147 male, 108 female; average age: 38 years; range: 40 days to 90 years) for whom at least 1-year follow-up data were available was performed. Abscesses were drained with fluoroscopic, sonographic, or computed tomographic guidance.

June 2005

Department of Endocrinology and Metabolism, Hacettepe University, Hacettepe Medical School, Ankara, Turkey.

Octreotide is the first somatostatin analogue to become available for clinical use in the treatment of acromegaly. To our knowledge, there are no reports describing lipoatrophy in patients treated with octreotide. Here, we report three patients who developed lipoatrophy after treatment with subcutaneous octreotide.

Osteocalcin. A biochemical marker of bone turnover during puberty.

Int J Adolesc Med Health

January 2003

Adolescent Unit, Department of Pediatrics, University of Hacettepe Medical School, Pediatrics, Ankara, Turkey.

During bone remodelling, osteocalcin is produced by osteoblasts and its level increases during the events characterized by rapid bone turnover. Osteocalcin is a bone matrix protein, which is specific for bone metabolism and it is not influenced by metabolic bone disorders. Osteocalcin is an important marker of bone turnover in physiological and pathological conditions.

Background: It is well known that there is a close relation between sudden cardiac death and serious ventricular tachyarrhythmias in patients with aortic valve stenosis (AS). QT dispersion (QTd) reflects the ventricular repolarization heterogeneity and has been proposed as an indicator for ventricular arrhythmias.

Hypothesis: This study investigated the QTd and its relevance to the clinical and echocardiographic variables.
