Ligamentum flavum analysis in patients with lumbar discus hernia and lumbar spinal stenosis.

The normal ligamentum flavum (LF) is a well-defined elastic structure with specific innervation. Several studies investigated LF in patients with lumbar spinal stenosis (LSS) and used lumbar discus hernia (LDH) patients as control group, only on the presumed thesis that LF in this patients have normal morphology. In patients with LSS thickening of the LF is the main cause of stenosis, which is most often presented with neurogenic claudication, whose pathophysiological mechanism is not completely understood.

Dural metastasis of prostate carcinoma misdiagnosed as a bilateral subdural hematoma: A case report.

Dural metastases originating from prostate cancer are exceedingly uncommon and may clinically imitate a subdural hematoma. Additionally, head computed tomography scan findings can be mistaken for meningioma or subdural hematoma. We present a 75-year-old male patient with dural metastasis as a first presenting sign of prostate cancer, misdiagnosed as a bilateral subdural hematoma on initial non-contrast brain CT scan.

Association between oxidative stress biomarkers and concentrations of some metal ions in the blood of patients with brain tumors and hydrocephalus.

Introduction: Any substance that induces production of free radicals can be a potential cause of brain damage. The aim of our study was to investigate the relationship between some metal ions and oxidative stress biomarkers in the blood of patients with brain tumor and hydrocephalus.

Material And Methods: Our study included 27 control subjects, 24 patients with brain tumor and 21 patients with hydrocephalus.

A Noninvasive Assistant System in Diagnosis of Lumbar Disc Herniation.

The purpose of this study is the application of pressure sensors in diagnostics and evaluation of the accuracy diagnostics of lumbar disc herniation at levels L4/L5 and L5/S1 using the aforementioned platform. The motivation behind the idea to apply the pressure measurement platform is the fact that the motor weakness of plantar and dorsal flexia of the feet is one of the absolute indications for the operative treatment of patients with lumbar disc herniation at the indicated levels. In patients, MRI diagnosis of the lumbosacral spine served as the ground truth in the diagnosis of herniation at L4/L5 and L5/S1 levels.

Thoracal arachnoiditis ossificans associated with multifocal motor neuropathy: a case report.

The association of arachnoiditis ossificans with acquired peripheral nerve disease is rare. We report a case who presented with progressive myelopathy due to arachnoiditis ossificans from prior trauma, complicated with multifocal motor neuropathy. Intradural bone was removed at surgery.

Efficacy of Early Rehabilitation After Surgical Repair of Acute Aneurysmal Subarachnoid Hemorrhage: Outcomes After Verticalization on Days 2-5 Versus Day 12 Post-Bleeding.

Aim: To develop a specific rehabilitation protocol for patients who have undergone surgical repair of acute aneurysmal subarachnoid hemorrhage (aSAH), and to determine the time at which verticalization should be initiated after aSAH.

Material And Methods: Sixty-five patients who underwent acute-term surgery for aSAH and early rehabilitation were evaluated in groups: Group 1 (n=34) started verticalization on days 2-5 post-bleeding whereas Group 2 (n=31) started verticalization approximately day 12 post-bleeding. All patients were monitored for early complications, vasospasm and ischemia.

Spontaneous Intracerebral Hematoma in Low-Grade Glioma After 14 Years of Follow-Up.

We are reporting the case of a 53-year old woman presenting to our hospital with a hemorrhagic low-grade glioma (LGG). She was admitted to a nearby general hospital where she had presented with aphasia, right hemiplegia and change of mental status. Computer tomography (CT) images showed a left temporo-parietal hemorrhage with mass effect.

Comparative analysis of the animal model and results of the clinical research of the aneurysm inclination angle as the predisposing factor for the occurrence of rupture.

Introduction: Natural course of aneurysms that occur on blood vessels of the brain singles out the need for understanding the mechanism of the occurrence of aneurysm wall rupture and identification of anatomic characteristics as predictive factors for hemorrhage to occur.

Objective: In this study we comparatively present results of our researches and experimental models on animals.

Methods: We made a comparative analysis of anatomical characteristics of blood vessels of the brain and aneurysms obtained on the basis of digital subtraction angiography and intraoperative finding.

Genomic instability and p53 alterations in patients with malignant glioma.

The purpose of this study was to detect the level of genomic instability and p53 alterations in anaplastic astrocytoma and primary glioblastoma patients, and to evaluate their impact on glioma pathogenesis and patients outcome. AP-PCR DNA profiling revealed two types of genetic differences between tumor and normal tissue: qualitative changes which represent accumulation of changes in DNA sequence and are the manifestation of microsatellite and point mutation instability (MIN-PIN) and quantitative changes which represent amplifications or deletions of existing chromosomal material and are the manifestation of chromosomal instability (CIN). Both types of alterations were present in all analyzed samples contributing almost equally to the total level of genomic instability, and showing no differences between histological subtypes.

The trigeminal vasculature pathology in patients with neuralgia.

Objective: To examine the possible pathological changes of the trigeminal vasculature in patients with neuralgia.

Background: Such a study has never been performed before. The alterations of the trigeminal vessels could have important pathophysiological implications in the trigeminal neuralgia pathogenesis.

[The role of surgical decompression of cauda equina in lumbar disc herniation and recovery of bladder function].

Introduction: Cauda equina syvndrome from lumbar disc herniation accounts for up to 2-3% of all disc herniations. The aim of this study was to investigate whether recovery of bladder function after surgery depends on preoperative duration of desease.

Patients And Methods: This retrospective study included 47 patients who underwent surgery for cauda equina syndrome due to a herniated disc in the period between 1997 and 2002.

[Epidural hematomas of the posterior fossa].

Background: Posterior fossa epidural hematomas represent 7-14% of all traumatic intracranial epidural hematomas. They are most frequently encountered posttraumatic mass lesions in the posterior fossa. The aim of this study was to identify clinical features that could lead to the early diagnosis of posterior fossa epidural hematoma.
