The effectiveness of extra-scrotal fixation following manual detorsion for testicular torsion: a pilot study in a rabbit model.

Introduction: To investigate the effectiveness of manual detorsion (MD) and applicability of extra-scrotal fixation for testicular torsion in a rabbit model.

Material And Methods: Twelve New Zealand male rabbits were randomized into six groups of two rabbits each. A single-side testicular torsion (TT) model (different degrees, time and sides) was performed in all groups except the Sham group.

Unenhanced 3D turbo spin echo MR angiography of lower extremity arteries: comparison with 128-MDCT angiography.

Purpose: This study aimed to investigate the feasibility and diagnostic power of unenhanced 3D turbo spin echo MR angiography sequence (a technique based on subtraction of corresponding images acquired in diastole and systole, Syngo Native Space-Siemens healthcare) to identify peripheral artery disease (PAD).

Materials And Methods: Thirty patients (619 arterial segments in total) suspected with PAD and who were assessed with lower extremity MDCT angiography were examined starting from the level of aortic bifurcation for both lower extremities by 3D native space MR angiography. Two readers assessed the image quality of native space MR angiography and number of lesions, their degrees of stenosis and localizations.

The comparison of high and standard definition computed tomography techniques regarding coronary artery imaging.

Objective: The aim was to compare coronary high-definition CT (HDCT) with standard-definition CT (SDCT) angiography as to radiation dose, image quality and accuracy.

Material And Methods: 28 patients with history of coronary artery disease scanned by HDCT (Discovery CT750 HD) and SDCT (Somatom Definition AS). The scan modes were both axial prospective ECG-triggered.

A novel approach for manual de-torsion of an atypical (outward) testicular torsion with bedside Doppler ultrasonography guidance.

A 17-year-old boy presented with right testicular torsion to the lateral side. Torsion was diagnosed by physical examination; the colour Doppler ultrasonography (CDU) confirmed right testicular torsion with minimal peripheral hydrocele. Transverse and longitudinal examination of the spermatic cord with ultrasound and CDU revealed a counter-clockwise testicular torsion.

Anti TNF-α therapy might be responsible for an increased incidence of varicocele in patients with ankylosing spondylitis.

Aim: To evaluate the effects of anti-tumor necrosis factor-alpha (TNF-α) therapy on the frequency of varicocele in patients with ankylosing spondylitis (AS) using color Doppler ultrasound.

Materials And Methods: The patients were divided into 2 groups: patients with AS who were on anti-TNF-α treatment and patients with AS who were not regularly taking any antiinflammatory drugs. Thirty-one healthy volunteers were included as controls.

CT-guided transthoracic biopsy: histopathologic results and complication rates.

Purpose: We aimed to investigate the effectiveness and complications of transthoracic CT-guided biopsy techniques.

Methods: A total of 94 CT-guided percutaneous transthoracic biopsy procedures performed in 85 patients were retrospectively evaluated. Core biopsy technique was used in 87 procedures and transthoracic fine-needle aspiration biopsy was used in seven procedures.

CT findings of patients with small bowel obstruction due to bezoar: a descriptive study.

PURPOSE. The aim of this study was to present the computed tomography (CT) findings of bezoars that cause obstruction in the small bowel and to emphasize that some CT findings can be considered specific to some bezoar types. MATERIALS AND METHODS.

A case of achalasia presented with cardiopulmonary arrest.

Achalasia is a rare disorder characterised by obstruction of the distal oesophagus and subsequent dilation of the proximal oesophagus. Patients generally complain of gastrointestinal symptoms; however, pulmonary symptoms and complications may also occur. A 35-year-old woman was brought to our emergency service complaining of sudden-onset dyspnea that started 15 minutes earlier during dinner.

Absence of middle hepatic vein combined with retro-aortic left renal vein: a very rare case report.

The hepatic and renal veins drain into the inferior vena cava. The upper group of hepatic veins consists of three veins which extend to the posterior face of the liver to join the inferior cava. The left renal vein passes anterior to the aorta just below the origin of the superior mesenteric artery.

Short pancreas: evaluation with multi-detector row CT.

Purpose: The purpose of this study was to analyze the length variations of the pancreas using computed tomography (CT) and establish a database for short pancreas.

Methods: We retrospectively reviewed CT examinations of 228 adults and rated pancreatic lengths qualitatively on a scale of 1-3 using transverse images. 1, normal pancreas length; 2, mildly short pancreas; and 3, markedly short pancreas.

A neck mass with brachial plexus injury: Pott's disease.

Tuberculous osteomyelitis of the spine is most commonly seen in lower thoracic and lumbar vertebrae. Cervical spine tuberculosis is a very rare condition, and it represents a very small part of all patients with Pott's disease. We present a case with thoraco-cervical Pott's disease, with left-sided neck mass and left arm and hand weakness and numbness.

Erratum to "Sonographic findings of the median nerve and prevalence of carpal tunnel syndrome in patients with Parkinson's disease" [Eur. J. Radiol. 67 (3) (2008) 546-550].

Purpose: Parkinson's disease (PD) is a chronic progressive disorder which is characterized by rest tremor, akinesia or bradykinesia and rigidity. Carpal tunnel syndrome (CTS) is caused by compression of median nerve and can occur as a result of repetitive trauma. The aim of this study was to estimate the prevalence of CTS in PD and evaluate the median nerve sonographically.

Vertebral body pneumatocyst in the cervical spine and review of the literature.

A pneumatocyst in the cervical spine is extremely rare and to our knowledge only a few reports have been published in the English literature. 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.

Effect of Aerodiol administration on ocular arteries in postmenopausal women.

Objective: The aim of the present study was to evaluate the alteration of ocular blood hemodynamics after intranasal administration of 17beta-estradiol, through measurement of the ophthalmic artery (OA) and the central retinal artery (CRA) using color duplex sonography.

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.

The aim of this study was to estimate the prevalence of CTS in PD and evaluate the median nerve sonographically.

Large mycotic aneurysm of the peroneal artery.

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.

We aimed to evaluate the effects of l-dopa use on apparent diffusion coefficient (ADC) values of different brain regions in Parkinson's disease (PD) patients. 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.
