Diagnostic value of S100B protein in the differential diagnosis of acute vertigo in the emergency department.

Objectives: Vertigo is a common presenting complaint resulting from central or peripheral etiologies. Because central causes may be life-threatening, ascertaining the nature of the vertigo is crucial in the emergency department (ED). With a broad range of potential etiologies, distinguishing central causes from benign peripheral causes is a diagnostic challenge.

Asymptomatic Chronic Epidural Hematoma in a Child As a Result of Extracranial Decompression.

Background: Epidural hematoma (EDH) in children is a diagnostic challenge due to its nonspecific clinical presentation. Asymptomatic chronic epidural hematoma is a very rare entity. Reports of spontaneous decompression into the subgaleal spaces are limited with acute epidural hematomas in the literature.

Diagnostic performance of conventional diffusion weighted imaging and diffusion tensor imaging for the liver fibrosis and inflammation.

Objective: To evaluate the diagnostic accuracy of liver apparent diffusion coefficient (ADC) measured with conventional diffusion-weighted imaging (CDI) and diffusion tensor imaging (DTI) for the diagnosis of liver fibrosis and inflammation.

Materials And Methods: Thirty-seven patients with histologic diagnosis of chronic viral hepatitis and 34 healthy volunteers were included in this prospective study. All patients and healthy volunteers were examined by 3T MRI.

Preoperative evaluation of myometrial invasion in endometrial carcinoma: diagnostic performance of 3T MRI.

Purpose: To evaluate the diagnostic accuracy of 3T MRI in preoperative staging of myometrial invasion.

Methods: Twenty-eight women with histological diagnosis of endometrial carcinoma were included in this prospective study. After T2-W SS-TSE and DWI, dynamic series of T1-W THRIVE images were obtained (0-180 s) followed by a T1-W THRIVE sequence in the late phase (5th min).

Objectives: We aimed to evaluate the performance of diffusion-weighted magnetic resonance imaging in differentiating malignant from benign mediastinal lesions.

Methods: Fifty-three mediastinal lesions were examined with T1- and T2-weighted (W) conventional images. Then, two diffusion-weighted images were obtained with b = 0 and 1000 s/mm² values and apparent diffusion coefficients (ADC) were calculated.

Post-traumatic cerebral infarction: a rare complication in a pediatric patient after mild head injury.

Because the cases of post-traumatic cerebral infarction in children are uncommon, little research has been done on this subject. The case of a 14-month-old child who had cerebral infarction after mild head injury is discussed. He fell from a height of approximately 70 cm 12 hours before.

Percutaneous renal artery stenting reduces arterial blood pressure, but what about renal function? A single-center experience.

Objective: To assess the effects of percutaneous transluminal angioplasty and stenting (PTRA/S) on arterial blood pressure and renal function.

Methods: A retrospective chart review of patients undergoing PTRA/S at our institution between December 2003 and September 2006 was done. Follow-up data were derived from hospital records.

"Figure of four" position improves the visibility of the sciatic nerve in the popliteal fossa.

Objectives: We studied the influence of patient positioning on the visibility of the sciatic nerve during ultrasound (US) examination in the popliteal region.

Methods: Using a linear broad band 7-12 MHz frequency probe, US examination of 24 sciatic nerves was performed by a blinded operator to obtain the best possible image at the level of the popliteal crease (PC) and at 4 and 8 cm above the PC in the prone position. Examinations were performed in neutral prone (Group N), with a silicone roller under the foot (Group R) and in "figure of four" (Group FOF) positions.

Diagnostic accuracy of real-time 3D sonography in the diagnosis of congenital Mullerian anomalies in high-risk patients with respect to the phase of the menstrual cycle.

Purpose: To compare the diagnostic accuracy of 2-dimensional sonography (2DUS) and real-time 3-dimensional sonography (3DUS) in the diagnosis of congenital mullerian defects (CMD) with respect to the phase of the menstrual endometrium.

Method: The accuracy of sonography was examined on 108 women by 2 gynecologists during the 1st 5 days after cessation of menstrual flow and then re-examined at the cycle days 20-24. Entrance criteria for the patients enrolled in the study were as follows: women who were referred to our center with a suspected Mullerian anomaly at hysterosalpingography, and women who were suspected to have a uterine anomaly at our hospital during infertility, dysmenorrhea, and recurrent abortion workup.

Evaluation of thoracic pedicle screw placement in adolescent idiopathic scoliosis.

Pedicle screw fixation is a challenging procedure in thoracic spine, as inadvertently misplaced screws have high risk of complications. The accuracy of pedicle screws is typically defined as the screws axis being fully contained within the cortices of the pedicle. One hundred and eighty-five thoracic pedicle screws in 19 patients that were drawn from a total of 1.

An unusual type of lateral compression injury of the pelvis tilt fracture with anterior displacement.

Tilt fracture is the most unusual variant of pelvic lateral compression injury. The major problem was reported to be protrusion of the pubic ramus into the perineum by posterior-inferior displacement of the fragment. Tilt fragment with anterior and inferior displacement has not been reported in English speaking literature to our knowledge.

Primary hydatid disease in adductor muscles.

Primary muscular Echinococcus infection is very rare without involvement of thoracic and abdominal organs. In this case a 31-year-old man who had a growing mass in the postero-medial part of his right thigh was examined. The mass was diagnosed as hydatid cyst using ultrasound, magnetic resonance imaging (MRI) and serological tests.

Materials And Methods: Fifteen patients with TBS, 15 with MTEC and 15 with MVD were included. MRS from the diseased vertebral body as well as normal vertebral body was examined.

A rare cause of headache: cerebral venous sinus thrombosis due to hyperthyroidism.

Headache represents up to 4% of all emergency department (ED) visits. Emergency physicians generally are concerned with identifying those patients whose headaches are caused by life-threatening conditions. Cerebral venous sinus thrombosis may be difficult to diagnose clinically because of its various and nonspecific manifestations.

Placement of pedicle screws in thoracic idiopathic scoliosis: a magnetic resonance imaging analysis of screw placement relative to structures at risk.

In posterior pedicle screw instrumentation of thoracic idiopathic scoliosis, screw malposition might cause significant morbidity in terms of possible pleural, spinal cord, and aorta injury. Preoperative axial magnetic resonance images (MRI) in 12 consecutive patients with right thoracic adolescent scoliosis, all with King type 3 curves, were analyzed in order to evaluate the relationship between the inserted pedicle screw position to pleura, spinal cord, aorta. Axial vertebral images for each thoracic level were scanned and the simulation of pedicle screw insertion was performed using a digital measurement programme.

Lipedematous scalp: a rare entity.

Lipedematous scalp is characterized by increased subcutaneous thickness of the scalp without any hair change. A 50-year-old female presented with thickening of the scalp without alopecia. She had no disorder other than hypertension.

Surgical technique and outcome in cervical and thoracic myelomeningocoele surgery.

Cervical and thoracic myelomeningocoeles differ from common lumbosacral myelomeningocoeles in many respects. We review the surgical technique and outcome achieved for a series of six infants who underwent surgery for cervical or thoracic myelomeningocoele. Five patients, who had intradural exploration and microsurgical untethering of the spinal cord, were neurologically stable on follow-up.
