Pitfalls of diagnosing pituitary hypoplasia in the patients with short stature.

Purpose: Height age (HA) and bone age (BA) delay is well known in the patients with short stature. Therefore assessing pituitary hypoplasia based on chronological age (CA) might cause overdiagnosis of pituitary hypoplasia. We aimed to investigate the diagnostic and prognostic value of the PH and PV based on CA, HA, or BA in the patients with GHD.

Our Single Center Experience in Osteoid Osteoma Patients Treated with CTGuided Percutaneous Radiofrequency Ablation Treatment and Follow-up.

Introduction: Osteoid osteoma (OO) is a painful benign bone tumor. Typically, it causes pain that is most noticeable during the night, which is improved by nonsteroidal anti-inflammatory drugs. In the treatment of symptomatic lesions, open surgery for nidus removal is the gold standard.

Facing the Pandemic: Burnout in Physicians in Turkey.

Objective: During the COVID-19 pandemic, physicians have been working for long hours, with the fear of contracting the disease and infecting their families. Therefore, there are great concerns about the mental health of physicians. In this research, we aimed to reveal the factors that affect the burnout among physicians working during the pandemic.

Poly(L-DOPA)-mediated bimetallic core-shell nanostructures of gold and silver and their employment in SERS, catalytic activity, and cell viability.

Core-shell gold nanorod (AuNR)@silver (Ag) nanostructures with their unique properties have gained enormous interest and are widely utilized in various applications including sensor systems, catalytic reactions, diagnosis, and therapy. Despite the recent progress, simple, effective, low-cost, and easy-to-tune strategies are heavily required to fabricate these nanoparticles (NP) systems. For this, we propose the employment of the polymer of 3,4-dihydroxyphenyl-L-alanine (L-DOPA) as a ligand molecule.

Age- and Sex-Related Morphometric Changes and Asymmetry in the Orbito-Zygomatic Region.

The aims of this study were to obtain cephalometric data of orbito-zygomatic skeleton using CT axial images and to determine the presence of sexual dimorphism, normal range of facial asymmetry, and the age-related changes.This study used data from 315 CT scan series of skeletally normal subjects (159 males and 156 females) between the ages of 18 to 90. Two different levels of axial sections were used.

CADASIL with Atypical Clinical Symptoms, Magnetic Resonance Imaging, and Novel Mutations: Two Case Reports and a Review of the Literature.

Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is a hereditary microangiopathy with adult onset caused by a missense mutation in the NOTCH3 gene in chromosome 19p13. It presents with autosomal dominant arteriopathy, subcortical infarctions, and leukoencephalopathy. Its common clinical presentations are seen as recurrent strokes, migraine or migraine-like headaches, progressive dementia, pseudobulbar paralysis, and psychiatric conditions.

Percutaneous embolization of congenital portosystemic venous shunt in an infant with respiratory distress.

Alkan F, Düzgün F, Yüksel H, Tarhan S, Coşkun Ş. Percutaneous embolization of congenital portosystemic venous shunt in an infant with respiratory distress. Turk J Pediatr 2018; 60: 456-459.

Hemodynamic Changes in Paramedian Forehead Flap.

Paramedian forehead flap is a workhorse for nasal reconstruction. However, vascular complications may lead to flap failure. The purpose of this study was to evaluate the blood flow objectively and determine the hemodynamic changes in paramedian forehead flap with respect to influential factors of age, gender, and smoking.

Determination of attitude and knowledge of type 2 diabetic patients towards insulin therapy in Northern Cyprus.

Objective: To determine the attitude and knowledge of type-2 diabetics related to insulin therapy.

Methods: The descriptive cross-sectional study was conducted from January to March 2014 at the Dr. Burhan Nalbantoglu Public Hospital, Nicosia in the Turkish Republic of Northern Cyprus, and comprised patients with type-2 diabetes.

Neonatal Cholestasis as Initial Presentation of Portosystemic Shunt: A Case Report.

Congenital intrahepatic portosystemic shunts are rare in children. Portosystemic venous malformations are characterized by extreme clinical variability. We report a full-term 33-day-old male infant presenting with neonatal jaundice.

Autologous Breast Augmentation Using Abdominal Dermis Fat Strip Grafts: A Preliminary Report.

Background: Abdominoplasty and augmentation mastopexy are often performed in the same operation. Although silicone breast implants are usually used for breast augmentation, resected abdominal dermis fat tissue can be used for this purpose. We describe a new autologous breast augmentation technique using dermis fat grafts obtained from a simultaneous abdominoplasty operation.

Direct and protective effects of single or combined addition of vincristine and ε-viniferin on human HepG2 cellular oxidative stress markers in vitro.

The objective of this study is to examine the direct effects of low doses and high doses of ε-viniferin, a substance known to be an antioxidant, and vincristine sulphate, a chemotherapeutic agent, alone and in combination [ε-viniferin + vincristine] on HepG2 cell strain, as well as evaluate oxidative stress after incubation periods of 3, 6, and 24 h. Direct effect was determined right after the incubation period; however, for protective effect, antioxidant protection response was determined after the treatment for 1 h with 500 μM H2O2, which is an oxidative stressor. For this purpose, superoxide dismutase was determined for enzyme activity, and lipid hydroperoxide (LPO) and reduced glutathione concentrations were studied as indicators of oxidative stress.

[Sinonasal-type haemangiopericytoma: a case report].

Sinonasal-type hemangiopericytomas, which comprise less than 0.5% of all sinonasal neoplasms, arise unilaterally in the nasal cavity as polypoid masses with a mean diameter of about 3 cm. A 34-year-old female patient was admitted due to nasal obstruction and epistaxis.

Prenatal diagnosis of congenital high airway obstruction syndrome: report of two cases and brief review of the literature.

Congenital high airway obstruction syndrome (CHAOS) is the obstruction of the fetal upper airways, which may be partial or complete. It is usually incompatible with life. Prenatal recognition of the disease is quite important due to the recently described management options.

Idiopathic Inflammatory Neuroretinitis Simulating Optic Nerve Sheath Dural Ectasia.

We report a case of a 32-year-old female patient who presented with decreased vision on both eyes and headache. In fundus examination, both eyes had elevation of the optic disc and star shaped hard exudates in the macula. Magnetic resonance imaging was completely normal except the saccular dilatation of bilateral optic nerve sheath.

Long-term effect of microsurgical inguinal varicocelectomy on testicular blood flow.

We aimed to investigate the long-term effect of microsurgical inguinal varicocelectomy on testicular blood flow using color Doppler sonography (CDS) in this observational study. A total of 30 patients clinically diagnosed with left varicocele who underwent a microsurgical inguinal varicocelectomy were examined 3 times with CDS for testicular blood flow parameters, first before, then 3 months after, and finally 6 months after the operation. CDS values of testicular blood flow (peak systolic velocity, end diastolic velocity, resistive index, and pulsatility index) were measured from testicular, capsular, and intratesticular arteries.

Perfusion computed tomography could be a new tool for single-session imaging of ureteric obstructive pathology: an experimental study in rats.

Background/purpose: Perfusion imaging redefines computed tomography (CT) as a technique that can now depict vascular physiology in addition to detailed anatomy. The major clinical applications of perfusion CT are in acute stroke and oncology. Currently, there are very limited data on the application of perfusion CT in urology.
