Histopathological Study of the Effects of Dura Adhesive Agents Used in Spinal Surgery Practice on Spinal Epidural Fibrosis in Experimental Animal Model.

Objective: Histopathological examination of the effects of Tisseel, Cova, Glubran and Coseal, which are used for sealing purposes in spinal surgery practice, on epidural fibrosis is aimed.

Methods: Forty Sprague Dawley rats were randomly divided into five groups in our study as Group 1 (n=8) control group (Laminectomy); Group 2 (n=8) Cova group (Laminectomy + Cova); Group 3 (n=8) Tissel group (Laminectomy + Tisseel); Group 4 (n=8) Coseal group (Laminectomy + Coseal); and Group 5 Glubrane group (Laminectomy + Glubrane). Control group was only applied laminectomy.

Solitary thoracic osteochondroma causing spinal compression: Case report.

Spinal osteochondromas are very rare, and they present with nonspecific localized pain owing to bone involvement. Diagnosis is made based on direct X-ray and computed tomography (CT) imaging of the exophytic bone lesion with pedunculated or sessile structure. Although asymptomatic patients can be observed, surgical excision is the main treatment modality.

Intrathecal and Intraventricular Administration of Antibiotics in Gram-Negative Nosocomial Meningitis in a Research Hospital in Turkey.

Aim: To evaluate the gram-negative nosocomial meningitis cases which were treated with intrathecal (IT) / intraventricular (IVT) antibiotics.

Material And Methods: Medical records were reviewed for IT/IVT antibiotherapy. Gram-negative nosocomial meningitis cases treated with IT/IVT antibiotherapy additional to systemic antibiotics were included.

The Relation Between Functional Anatomy of the Face and Threat Perception Evoked by Facial Expression of Anger in Schizophrenia.

Introduction: It is well known that patients with schizophrenia are more sensitive to negative rather than positive feelings. In this study, we aimed to evaluate the degree of explicitly perceived threat against facial expressions of anger. We were also interested in the association between perceived threat, and both the objective intensity of facial expression of anger and the functional anatomy of the perceived faces.

5-Fluorouracil induces arterial vasoconstrictions but does not increase angiotensin II levels.

Because the mechanisms of 5-Fluorouracil (5-FU) cardiotoxicity have not yet been completely identified, prophylactic options are not available. To our knowledge, there are no published data investigating the use of angiotensin converting enzyme (ACE) inhibitors for 5-Fluorouracil-associated cardiotoxicity. In this study, we aimed to evaluate the influence of 5-FU administration on the diameter of the brachial artery and the levels of angiotensin II.

Spontaneous migration of a bullet into the brain.

We report the case of a 20-year-old man with a gunshot injury as an example of spontaneous migration of a metallic foreign body within the brain. Computed tomography (CT) showed the bullet in the left temporoparietal region. At 10 days follow-up, CT revealed that the bullet had migrated posteriorly, due to the effect of gravity, lodging in the occipital lobe.

Sexual dimorphism and handedness in the human corpus callosum based on magnetic resonance imaging.

The corpus callosum (CC) is a major anatomical and functional commissure linking the two cerebral hemispheres. With MR imaging in the sagittal plane, the corpus callosum can be depicted in great detail. Mid-sagittal magnetic resonance images of 80 normal individuals were analyzed to assess whether or not the morphology of the corpus callosum and its parts are related to sex and handedness.

[Cranial MRI findings in epileptic children].

Purpose: To investigate the cranial MRI findings in childhood epilepsy and to detect the most frequent cerebral lesions in epileptic children in our region.

Materials And Methods: In this study, 98 epileptic children were examined with 1 T MRI equipment between January 1997 and March 2001. T1-weighted sagittal, T2 and proton weighted axial and T2-weighted coronal MR images were obtained.

Timing of shunt surgery in childhood tuberculous meningitis with hydrocephalus.

Hydrocephalus is a common complication of tuberculous meningitis (TBM) in children. The aims of this study are to review our experience of hydrocephalus in childhood TBM and to evaluate the effect of the timing of ventriculoperitoneal shunting (VPS) on the final outcome. In this study, 156 patients with TBM and hydrocephalus were reviewed retrospectively between 1990 and 2000.

Analysis of 107 civilian craniocerebral gunshot wounds.

In this study, we present a retrospective analysis of 107 cases due to civilian craniocerebral gunshot wounds that were treated by the medical faculty of Dicle University during a period of 7 years (January 1993 to January 2000). Twenty patients died at the hospital, and the deaths were determined to result from direct effects of brain damage. Coma was the best prognostic guideline.

Effect of chemotherapeutic agents on distraction osteogenesis. An experimental investigation in rabbits.

Limb-salvage operations such as vascularised or non-vascularised osseous grafts and allograft and callus distraction methods have replaced amputations because of the increase in the life expectancy of patients with malignant tumours. In this study we aimed to evaluate the effects of chemotherapeutic agents on distraction osteogenesis. For this purpose, 23 rabbits randomly divided into two groups were included in the study.

Castleman's disease in the porta hepatis.

We report the CT, ultrasonographic, and pathologic features of a localized forms of Castleman's disease in the porta hepatis due to their unusual location. Our report suggests that the CT and the ultrasonographic features of Castleman's disease in these locations without calcifications is nonspecific.

Characteristics of penetrating abdominal firearm injuries in children.

Penetrating injuries of the abdomen which occur primarily from gunshots and stabbing become increasingly prevalent in children. Our purpose is to assess the presentation, management and outcome of children with penetrating abdominal firearm injuries (PAFI) and to evaluate the value of Injury Severity Score (ISS) for predicting injury severity and eventual morbidity and mortality in children with PAFI. Between 1985 and 1997, 69 children < or = 15 years of age with PAFI were hospitalized at our institution.

Normal configuration of the anterior commissure of the glottis on magnetic resonance imaging.

The purpose of this study was to evaluate the normal width of the anterior commissure of the glottis by measuring its dimensions in patients who had no laryngeal disease on magnetic resonance imaging (MRI), but had unrelated cervical pathology. In all, 27 patients were studied. Axial images through the arytenoid commissure at the level of the vocalis muscle and/or vocal process of the arytenoid cartilage were magnified on MRI.

Spinal subdural tuberculous abscess.

Objectives: Spinal subdural abscess is rare and only 48 cases have been described to date. In this report, we present an additional spinal subdural tuberculous abscess.

Method: Tuberculous meningitis was diagnosed with clinical and laboratory findings in a 45-year-old man.

Limb reconstruction with the callus distraction method after bone tumor resection.

The callus distraction method was applied to nine patients who were referred to us because of a bone tumor. Their mean age was 17 years and 3 months (range 7-37 years). Three were female, and 6 were male.
