Objectives: Bariatric surgery is an effective intervention for severe obesity and associated comorbidities. We compared symptoms, joint space and life quality of morbidly obese patients with symptomatic knee osteoarthritis before and after bariatric surgery.
Methods: 34 patients with knee osteoarthritis were evaluated with standing anteroposterior and lateral radiography, medial and lateral joint distances of the knees, Visual Analog Scale (VAS), Western Ontario and McMaster Universities Arthritis Index (WOMAC) questionnaire and the Short Form 36 (SF-36) before and 6 months after surgery.
The aims of this retrospective study were to consider the diagnostic role of dual-time F-fluorodeoxyglucose positron emission tomography and computed tomography (F-FDG PET/CT) in detection of breast carcinoma and axillary lymph node (ALN) status and to evaluate the primary tumor F-FDG uptake pattern. Preoperative staging was performed by F-FDG PET/CT in 78 female patients with breast carcinoma. Conventional imaging results were evaluated by breast magnetic resonance imaging (MRI) of 79 lesions in 78 patients, bilateral mammography (MMG) of 40 lesions in 40 patients, and breast ultrasonography (USG) of 47 lesions in 46 patients.

The purpose of this study was to evaluate the association between RI values of orbital arteries by using the color Doppler imaging (CDI) in type II diabetes mellitus (DM) patients with microalbuminuria.
Patients And Methods: We evaluated 91 type II DM patients with microalbuminuria and 27 healthy subjects.

The aim of the kyphoplasty method for the treatment of traumatic osteoporotic vertebral compression fractures in geriatric patients is to improve the patient's quality of life. In this report we present two elderly patients who were suffering of traumatic osteoporotic vertebral compression fractures and underwent successful kyphoplasties. Percutaneous kyphoplasty method for the surgical treatment of these fractures decreases the hospitalization, morbidity and mortality in these patients.

Although the etiology and natural course of vertebral body pneumatocyst is unclear, nitrogen gas accumulation is claimed. A 65-year-old-man was admitted to the emergency department with neck pain and numbness and incapacity in his both hands and fingers.

Any of the abdominal organs can slide into the hernial sac and become incarcerated there. In girls, the fallopian tubes, ovaries, uterus, and-rarely-ovarian cysts can form the sliding component of an inguinal hernia.

Methods: Thirty healthy women who had been naturally postmenopausal for at least 1 year were enrolled in the study. A randomized, placebo-controlled, crossover, double-blinded study was conducted of the acute effect of 17beta-estradiol (Aerodiol; Servier, Chambrayles-Tours, France) on OA and CRA blood flow using color duplex sonography.
Background: Atherosclerotic vascular disease is a major cause of morbidity and mortality for patients with end-stage renal disease on maintenance hemodialysis. Early atherosclerotic changes of the arterial wall can be evaluated by intima-media thickness (IMT), presence and structure of plaques and parameters of vascular resistance. The aim of the present study has been to investigate the relationship between carotid IMT and pulsatility index (PI) or resistive index (RI) values in hemodialysis patients.

NAFLD can progress without associated elevations in liver enzymes. Therefore, we investigated the effects of weight loss on normal transaminase levels in obese subjects who are at risk for NAFLD.

The aim of this study was to evaluate the relationship between blood flow rate of AV fistula and pulmonary artery pressure (PAP) in hemodialysis patients.
Methods: Thirty-two hemodialysis patients were included in this study.
We describe the case of a 37-year-old patient with mycotic aneurysm of the right peroneal artery associated with episodes of endocarditis. There are only 7 cases of mycotic aneurysms of the crural arteries reported in the literature. To the best of our knowledge, this is the first reported case of a mycotic aneurysm of the peroneal artery in an adult.

Thirty-five subjects underwent magnetic resonance imaging (MRI), including 21 PD patients (13 men, 8 women; mean age, 63 years+/-8), and 14 sex and age-matched control subjects. PD patients were separated into two groups according to the duration of l-dopa usage: patients using l-dopa less and more than 1 year.

Introduction: We investigated the diffusion-weighted MRI changes, apparent diffusion coefficient (ADC) values, and conventional MRI findings in specific brain areas during migraine attacks in patients with and without aura.
Methods: Included in the study were 22 patients (2 male, 20 female) aged between 17 and 49 years who were diagnosed as having migraine according to the diagnostic criteria of the International Headache Society. Also included in the study were 18 age- and sex-matched healthy volunteers.
Purpose: To measure with Doppler sonography the velocity and volume of blood flow in the extracranial internal carotid artery (ICA) and vertebral artery (VA) of healthy adults and to calculate total cerebral blood flow volume (tCBFV).
Methods: Bilateral ICA and VA were examined sonographically in 180 healthy adults. Angle-corrected peak systolic (Vps), end-diastolic (Ved), and time-averaged maximum blood flow velocity (TAV) were measured in pulsed Doppler mode, and the resistance index (RI) and pulsatility index (PI) were calculated.

Introduction: We aimed to determine hemodynamic alterations in renal arteries that may have resulted from oral intake of sildenafil citrate in healthy volunteers.
Materials And Methods: Twelve healthy volunteers were included in our study. Renal Doppler ultrasonography (US) was performed before the drug intake to assess the basal values.
Objective: Sildenafil stimulates the nitric oxide-cyclic guanosine monophosphate (NO-cGMP) pathway through inhibition of type 5 phosphodiesterase. NO-cGMP pathway causes smooth muscle relaxation. The aim of this study is to evaluate the effects of sildenafil on gallbladder motility.
