This study was evaluated effects of exogenous sphingosylphosphorylcholine (SPC) administration on CIN in rats. Eight animals were included in each of the following eight groups: control, control phosphate-buffered solution (PBS), control SPC 2, control SPC 10, CIN, CIN PBS, CIN SPC 2 and CIN SPC 10.

Spontaneous intracranial hypotension presenting with coma: a case report and literature review.

Spontaneous intracranial hypotension is characterized by orthostatic headache in the absence of a history of head trauma or lumbar puncture, and diagnosis is confirmed by a specific cerebrospinal fluid pressure and neuroimaging findings. It rarely presents with coma. A 62-year-old man presented with progressive cognitive decline of 2 to 4 weeks' duration.

Extraspinal Incidental Findings on Routine MRI of Lumbar Spine: Prevalence and Reporting Rates in 1278 Patients.

Objective: The aim of the present study was to determine the prevalence and reporting rate of incidental findings (IF) in adult outpatients undergoing lumbar magnetic resonance imaging (MRI).

Materials And Methods: Re-evaluation of a total of 1278 lumbar MRI images (collected from patients with a mean age of 50.5 years, range 16-91 years) captured between August 2010-August 2011 was done by a neuroradiologist and a musculoskeletal radiologist.

Reversible hepatocerebral degeneration-like syndrome due to portovenous shunts.

Ataxia and tremor are rare manifestations of hepatocerebral degeneration due to portovenous shunts. Ammonia is a neurotoxin that plays a significant role in the pathogenesis of hepatic encephalopathy. A 58-year old male patient was assessed with the complaints of gait disturbance, hand tremor, and impairment of speech.

Frequency, distribution and severity of prevalent osteoporotic vertebral fractures in postmenopausal women.

Aim: Assessment of previous vertebral fractures provides useful information to predict future fracture risk. This study aimed to determine the frequency, distribution and severity of prevalent osteoporotic vertebral fractures in postmenopausal women.

Material And Methods: Data on patient characteristics, bone densitometry values, and spine radiographs (T2-L5) were reviewed in 232 postmenopausal women admitted to our osteoporosis clinic.

Subdural and cerebellar hematomas which developed after spinal surgery: a case report and review of the literature.

Cerebellar hemorrhage following a spinal surgery is extremely rare; however, considering the localization, it can cause major clinical manifestations. While it is considered that these types of bleedings occur secondary to a venous infarct, the pathogenesis is still unclear. A 57-year-old male patient who underwent a laminectomy by exposing T12-L5 and had pedicle screws placed for ankylosing spondylitis developed a CSF leak due to a 2 mm dural tear.

Intracranial hypotension is a rare cause of orthostatic headache: a review of the etiology, treatment and prognosis of 13 cases.

Objectives: The aim of this investigation is to examine the causes, clinical picture, treatment, and prognosis of spontaneous intracranial hypotension, a rare cause of orthostatic headache, among the cases presenting in our clinic.

Methods: Thirteen cases (5 males and 8 females), diagnosed with spontaneous intracranial hypotension in our clinic between January 1st, 2009 and October 30th, 2011, were included in this study. The presenting symptoms, treatment, findings on cranial magnetic resonance imaging, cerebrospinal fluid pressure measured at lumbar puncture (in available patients), and the healing period of the patients were recorded.

The effect of admission blood pressure on the prognosis of patients with intracerebral hemorrhage that occurred during treatment with aspirin, warfarin, or no drugs.

Background: Hypertension is the most important modifiable risk factor for intracerebral hemorrhage (ICH), but blood pressure (BP) management during the acute phase of ICH is still controversial. Approximately one-fourth of ICHs occur during treatment with warfarin or aspirin.

Aim: This study was designed to determine the effect of admission BP on the early prognosis of ICH patients by dividing them into three groups (warfarin, aspirin, and no drugs).

Subclinical atherosclerosis in gouty arthritis patients: a comparative study.

We evaluated the incidence of subclinical atherosclerosis and associated factors in our gouty arthritis patients. We included 55 gouty arthritis patients diagnosed at our center within the last 4 years. The control group included 41 patients with rheumatoid arthritis (RA) and 34 patients with asymptomatic hyperuricemia (AHU).

Diaphragmatic movements in ankylosing spondylitis patients and their association with clinical factors: an ultrasonographic study.

We compared diaphragmatic motion between ankylosing spondylitis (AS) patients and controls, as assessed by the ultrasonographic method. We included 33 consecutive AS patients (19 males, 14 females) followed up at our center and 14 apparently healthy controls (8 males, 6 females) into our study. AS patients fulfilled the modified New York classification criteria for AS.

Incidental pancreatic lipomas: computed tomography imaging findings with emphasis on diagnostic challenges.

Purpose: The purpose of this study was to describe the computed tomography (CT) findings of pancreatic lipomas of 9 cases, with emphasis to diagnostic challenges.

Methods: Between March 2006 and April 2008, 9 patients with pancreatic lipomas that were diagnosed by CT were reviewed in the present study. Clinical data and CT features of these 9 cases were retrospectively analysed.

Prevalence and MDCT characteristics of asymptomatic Bochdalek hernia in adult population.

Purpose: To determine the frequency of asymptomatic incidental Bochdalek hernias in adults, using multidetector computed tomography (MDCT), and to ascertain any possible relationship between Bochdalek hernia and age, gender, or body mass index (BMI).

Materials And Methods: Seven hundred and forty-eight abdominal, and 602 chest MDCT scans, which had been performed for a variety of reasons on 1350 adults, were investigated retrospectively. Location and size of Bochdalek hernias seen on these scans were correlated with age, gender, and BMI.

Postural tremor as a manifestation of spontaneous intracranial hypotension.

Spontaneous intracranial hypotension (SIH) is a syndrome caused by low cerebrospinal fluid (CSF) pressure due to leakage of CSF. Clinically, orthostatic headache, neck pain, nausea, emesis, interscapular pain, diplopia, dizziness, changes in hearing, visual blurring and radicular upper extremity symptoms are most frequently observed. We describe a 57-year-old man with SIH who presented with postural tremor.

Digital subtraction angiography of a persistent trigeminal artery variant.

Persistent trigeminal artery variants are described as cerebellar arteries that directly originate from the precavernous segment of the internal carotid artery. This has been observed in 0.18% of cerebral catheter angiograms.

CT-angiographic demonstration of hepatic collateral pathways due to superior vena cava obstruction in Behçet disease.

Behçet disease (BD) is a chronic multisystemic inflammatory disorder, mainly characterized by recurrent oral and genital ulcers, skin lesions, and uveitis. Large vein thrombosis in BD is unusual; when present, it is most frequently seen in the inferior or superior vena cava (SVC). The authors describe an unusual hepatic pseudolesion caused by abnormal focal enhancement through collateral pathways to the liver in two BD patients with SVC occlusion on three-dimensional multi-detector computed tomography, using volume rendering and maximum intensity projection techniques.

Computed tomographic and magnetic resonance imaging findings of asymptomatic intra-abdominal gastrointestinal system lipomas.

Lipomas are common benign mesenchymal neoplasms documented in literature. This study aimed to describe the computed tomographic (CT) and magnetic resonance imaging (MRI) findings of gastrointestinal system lipomas, all of which are incidentally found in routine abdominal imaging studies. Lipomas were depicted as homogeneous, nonenhancing, well-marginated lesions consistent with adipose tissue on CT and MRI.

Stroke due to bee sting.

Although bee stings can cause local reactions, neurovascular complications are rare. A 60-year-old man developed a focal neurologic deficit 2 hours after multiple bee stings, which was confirmed to be acute cerebral infarctions on magnetic resonance imaging scan.
