Yalçın K, Tüysüz G, Kazan S, Gürer Eİ, Karaali K, Küpesiz A, Güler E. An infant with intradural extramedullary synovial sarcoma: the youngest case in the literature. Turk J Pediatr 2019; 61: 765-770.

Evaluation of Cortical Brain Parenchyma by Diffusion and Perfusion MRI Before and After Chronic Subdural Hematoma Surgery.

Aim: To evaluate microcirculatory changes in neighboring parenchyma as a result of pressure due to chronic subdural hematoma (CSDH) in early and late periods after hematoma drainage.

Material And Methods: The subject group consisted of 25 patients who underwent CSDH drainage. Brain diffusion and perfusion magnetic resonance images (MRIs) were obtained preoperatively, and at 48 hours (early period) and 2 months (late period) postoperatively.

Spontaneous Shrinkage of a Suprasellar Arachnoid Cyst Diagnosed with Prenatal Sonography and Fetal Magnetic Resonance Imaging: Case Report and Review of the Literature.

Arachnoid cysts (AC's) are congenital anomalies that occur within the cerebrospinal fluid (CSF) cisterns and major cerebral fissures. Suprasellar AC's comprise 5-12.5% of all the lesions.

The effect of amifostine on pathophysiological changes in vasogenic brain edema induced by an experimental cold injury model.

Aim: To investigate the effects of amifostine, a cytoprotective agent, on pathophysiological changes in vasogenic brain edema induced by an experimental cold injury model and to compare these changes with dexamethasone.

Material And Methods: A total of 138 rats divided into 6 groups. Brain water content (BWC), malondialdehyde (MDA) concentration and myeloperoxidase (MPO) activity in brain tissue were calculated to evaluate the pathophysiological changes following experimental cold injury.

Effects of decompressive surgery in patients with severe traumatic brain injury and bilateral non-reactive dilated pupils.

Background: We investigated Glasgow Coma Scale (GCS) scores, intracranial pressure (ICP) and cerebral perfusion pressure (CPP) changes, and long-term clinical outcomes in patients with severe traumatic brain injury (STBI) associated with bilateral non-reactive dilated pupils (BNDP) who underwent decompressive surgery (DS).

Methods: The study group consisted of 28 patients (11 females, 17 males) with BNDP from among 147 patients who underwent DS due to STBI in our department.

Results: The mean GCS score was 4.

Sutural diastasis caused by pseudotumor cerebri.

The diagnosis of pseudotumor cerebri is based on the triad of: (1) papilloedema, (2) elevated intracranial pressure with a normal cerebrospinal constituency and (3) normal central nervous system imaging studies. However, the diagnosis of pseudotumor cerebri is not always straightforward. We report a 19-year-old morbidly obese girl who developed pseudotumor cerebri associated with sutural diastasis of the cranium based on the direct radiographies.

Outcomes of intrathecal baclofen (ITB) therapy in spacticity.

Aim: Spasticity is associated with various neurological conditions. Intrathecal baclofen (ITB) is one of the popular treatments for severe spasticity. In this paper we present our experience in treating 30 patients with both spinal and supraspinal spasticity with chronic infusion of Baclofen to evaluate the long term efficacy of this treatment on spasticity, disability and pain, and to evaluate the side effects of intrathecal Baclofen.

Effect of early bilateral decompressive craniectomy on outcome for severe traumatic brain injury.

Aim: Debate continues as to whether decompressive craniectomy (DC) is an effective treatment for severe traumatic brain injury (STBI). DC is mostly used as a second tier treatment option. The aim of this study was determined whether early bilateral DC is effective as a first tier treatment option in patients with STBI.

Multilevel primary intraspinal PNETs in an infant associated with hydrocephalus.

PNETs of the spinal cord are aggressive and local recurrence and/or leptomeningeal spread is common. Primary spinal PNETs are extremely rare and most cases involving the spinal cord are drop metastases from primary intracranial tumors by cerebrospinal fluid. Herewith, we present a 40-day-old infant with multilevel primary spinal PNET at Th12-L1 and L5-S1 levels associated with hydrocephalus occurring nearly 15 days after the operation.

Spontaneous resolution of a large chronic subdural hematoma: a case report and review of the literature.

Spontaneous resolution of a chronic subdural hematoma has been reported rarely in the literature. We present herein the case of a 35-year-old patient with spontaneous resolution of a large chronic subdural hematoma, the volume of which was measured as approximately 76.5 ml on magnetic resonance imaging.

Primary atypical teratoid/rhabdoid tumor of the clival region. Case report.

An atypical teratoid/rhabdoid tumor of the central nervous system (CNS) is a rare, aggressive neoplasm found in infants and children that has similar characteristics to CNS primitive neuroectodermal tumors/medulloblastomas. The authors present the case of a patient with an atypical teratoid/rhabdoid tumor and discuss the imaging, histopathological, immunohistochemical, and cytogenetic findings. Tumor cells displayed positive reactions for vimentin, epithelial membrane antigen, and cytokeratin, and they displayed no reaction for glial fibrillary acidic protein, desmin, and actin.

Modified experimental mild traumatic brain injury model.

Background: Experimental models of traumatic brain injury (TBI), using a variety of techniques and species, have been devised with the aim of producing repeatable lesions resembling those found in head injuries. There are various TBI models mentioned in the literature. In experimental head trauma models, emphasis has been placed on the severe head injuries.

Role of decompressive surgery in the management of severe head injuries: prognostic factors and patient selection.

Decompressive surgery or craniectomy (DC) is a treatment option, which should be considered when the intracranial pressure (ICP) cannot be treated by conservative methods. The purpose of this study was to evaluate the benefits of decompressive craniectomy in patients with intractable posttraumatic intracranial hypertension and to evaluate the patient selection criteria for this management protocol. In this study, 100 patients with severe head injuries were involved.

Hydrocephalus after intraventricular hemorrhage in preterm and low-birth weight infants: analysis of associated risk factors for ventriculoperitoneal shunting.

Background: Intraventricular hemorrhage and posthemorrhagic hydrocephalus are common causes of neonatal morbidity and mortality among preterm and low-birth weight infants (PT-LBWIs). Clinical management of posthemorrhagic hydrocephalus (PHH) is difficult and not well standardized. In this study, we aimed to determine the incidence of hydrocephalus after intraventricular hemorrhage (IVH) and the associated risk factors for ventriculoperitoneal (V-P) shunting in PT-LBWIs.
