Prognostic Impact of Histologic Subtype in Non-Small Cell Lung Cancer Patients Treated with Gamma Knife Radiosurgery: Retrospective Analysis of 104 Patients.

Aim: In this study, factors affecting survival, local failure, distant brain failure, whole brain failure and whole-brain radiation therapy (WBRT) free survival according to histological subtypes were investigated in patients with brain metastases from non-small cell lung cancer (NSCLC).

Material And Methods: Patients with positive pathology reports for adenocarcinoma (ACA) and squamous cell carcinoma (SCC) were included in the study. Seventy-eight ACA and 26 SCC patients were included in the study.

Rapid Spontaneous Resolution of Acute Epidural Hematoma: A Case Report and Review of the Literature.

Background: Epidural hematomas (EDH) are pathologies in which the early diagnosis and treatment are important. Resolution under 24 hours is very rare.

Case Report: An 11-month-old male patient was brought to the emergency department with head trauma from falling out of bed onto his back.

A extremely rare case of cervical intramedullary granuloma due to Brucella accompanied by Chiari Type-1 malformation.

Chiari Type-1 malformation is displacement of the cerebellar tonsils through the foramen magnum into the cervical spine and usually does not exceed the level of C2. It is 50-70% associated with syringomyelia. Nervous system involvement due to brucellosis is called neurobrucellosis, and neurological involvement rate has been reported an average of 3-5%, ranging between 3% and 25% at different series.

Delayed radiation myelopathy: Differential diagnosis with positron emission tomography/computed tomography examination.

Myelopathy is a rare but serious complication of radiation therapy (RT). Radiation myelopathy is white matter damage to the spinal cord developed after a certain period of application of ionizing radiation. Factors such as radiation dose and time between applications affect the occurrence as well as the severity of myelopathy.

Five-year follow-up results for patients diagnosed with anaplastic astrocytoma and effectiveness of concomitant therapy with temozolomide for recurrent anaplastic astrocytoma.

Background: Anaplastic astrocytoma (AA; WHO grade-III) patients determination of prognostic factors helps generating multimodal therapy protocols. For this purpose, in the Baskent University, Adana Medical Research Center, specific characteristics of AA patients who have surgery were retrospectively investigated and factors which affect prognosis has been determined.

Patients And Methods: Between January 2005 and 2009, 20 patients who have AA have been evaluated retrospectively.

Comparison of E-selectin and the other inflammatory markers in lumbar disc herniation: a new promising therapeutical window for radicular pain.

Study Design: Histopathologic and immunohistochemical analysis of the herniated disc specimens obtained from 50 patients who had unilateral persistent radicular pain or unilateral radicular motor paresis.

Objective: The aim of this study was to investigate the prevalence of inflammatory cells in lumbar disc herniations (LDH) and compare the prevalence of leukocyte adhesion protein "E-selectin" with other inflammatory cells such as T cells, B cells, and macrophages.

Summary Of Background: Studies on inflammatory cells and biochemical mediators of inflammation have suggested that these factors may play an important role in pathophysiology of radicular pain, and the medical therapy was formed against to block these cells and inflammatory cytokines.

Recurrent ischemic stroke as an initial manifestation of an concealed pancreatic adenocarcinoma: Trousseau's syndrome.

In rare instances, stroke may precede a diagnosis of cancer and be the first clinical evidence of an underlying malignancy.Cerebral infarction mostly complicates lymphomas, carcinomas, and solid tumors. Malignancy-related thromboembolism can present as acute cerebral infarction, nonbacterial thrombotic endocarditis and migratory thrombophlebitis.

Factors associated with the thickness of the ligamentum flavum: is ligamentum flavum thickening due to hypertrophy or buckling?

Study Design: Ligamentum flavum (LF) thickness was measured by using lumbar magnetic resonance imaging in patients with low back or leg pain.

Objective: This study investigated whether LF thickening is due to hypertrophy or buckling related to disc degeneration and examined the correlations between the thickness of the LF and age, sex, body mass index (BMI), degree of pain, lumbar spinal stenosis (LSS), and disc herniation.

Summary Of Background Data: "LF thickness" and "LF hypertrophy" are used interchangeably in the literature, although they are not necessarily the same thing.

A rare but fatal case of granulomatous amebic encephalitis with brain abscess: the first case reported from Turkey.

The incidence of protozoal and helminthic infestations of the central nervous system (CNS) is less than 1%, but these infestations tend to follow a fatal course. They are more common among children, the elderly and immunocompromised individuals. CNS infections due to Entamoeba histolytica have been known for a long time.

Therapeutic Difficulty in a Case of Supratentorial Primitive Neuroectodermal Tumor Diagnosed during Pregnancy.

We report a supratentorial primitive neuroectodermal tumor (sPNET) in 17-year-old primipara in the second trimester her pregnancy. Magnetic resonance imaging revealed a left frontoparietal mass with solid and cystic component. Gross-total resection was achieved via a left frontoparietal craniotomy.

A non-bleeding complex intracerebral giant aneurysm case: case report.

An intracranial aneurysm with a diameter larger than 25 mm is considered a giant aneurysm (GA), and represent about 3-5% of all aneurysms. They are divided into two forms, specifically saccular and fusiform. Fusiform aneurysms are rare, making up only 1% of all intracranial aneurysms.

Is topical tissue plasminogen activator application effective on prevention of post-laminectomy epidural fibrosis? An experimental study.

Objective: Impaired fibrinolytic activity has been shown to be associated with poor outcome after lumbar disc surgery. The purpose of this study was to determine the efficacy of topical tissue plasminogen activator (t-PA) in preventing epidural fibrosis in rats.

Methods: L4-L5 laminectomy was performed under surgical microscope in 40 rats.

A rare case of massive NF1 with invasion of entire spinal axis by neurofibromas: case report.

Neurofibromatosis type-1 (NF1) is a type of phakomatosis inherited in an autosomal dominant fashion. Also called 'von Recklinghausen disease' or 'peripheral neurofibromatosis', it comprises 90% of all neurofibromatosis (NF) cases. It is characterized by multiple peripheral nerve sheath tumors of benign character called neurofibromas.

Endovascular treatment of primary infectious aneurysm in childhood: a case report.

Infectious aneurysms constitute 4% of all intracranial aneurysms. The microorganisms responsible are most commonly streptococcus viridans, staphylococcus aureus and combined bacterial infections. Nonetheless, cases with no reproduction in their cultures are rather frequent.
