INTRODUCTION Blood blister-like aneurysms (BBAs) are fragile and difficult to treat. Routine surgical and endovascular treatment methods, such as clipping, clip wrapping, primary coiling, or stent assisted coiling, have relatively high morbidity and mortality rates. In this study, we report clinical and angiographic results for treatment of ruptured BBAs(More)
A patient with an intrasellar germinoma leading to pituitary stalk thickening is reported. The patient, a 24-year old woman, presented with hyperprolactinemia, secondary hypothyroidism, and hypogonadotropic hypogonadism with no evidence of diabetes insipidus. Cerebrospinal fluid (CSF) examination revealed an increased number of lymphocytes and histiocytes.(More)
BACKGROUND We investigated the individual and combined effects of magnesium sulphate, which is an N-Methyl-D aspartate receptor antagonist (NMDA), and z-LEHD-FMK, which is a caspase 9 inhibitor, on the genesis of secondary injury in a rat spinal cord injury model. We aimed to minimize the effects of secondary injury in spinal cord trauma by choosing these(More)
BACKGROUND Traumatic EDHs of the posterior cranial fossa are rare and have a higher mortality than supratentorial localizations. Early diagnosis of TEHPCF and prompt surgical evacuation provide excellent recovery. Active use of cranial CT scanning has taken a major role in the diagnosis, surgical indication, close observation, and strategy planning. As a(More)
OBJECT Traumatic posterior fossa epidural hematoma (PFEDH) is rare, but among children it may have a slightly higher incidence. With the widespread use of CT scanning, the diagnosis of PFEDH can be established more accurately, leading to an increased incidence of the lesion and possibly to a better patient prognosis. This study presents 40 pediatric cases(More)
OBJECTIVE Glutamate antagonists are very attractive drugs in laboratory works to protect neural tissue against ischemia. In this work, the effects of magnesium, MK-801 and combination of magnesium and MK-801 on blood-brain barrier (BBB) and brain edema after experimentally induced traumatic brain injury are evaluated. METHODS A standard closed head injury(More)
OBJECTIVE Intrathecal gadolinium (Gd)-enhanced magnetic resonance (MR) cisternography is a newly introduced imaging method. Two main objectives of this study were to investigate the sensitivity of Gd-enhanced MR cisternography for presurgical localization of cerebrospinal fluid (CSF) leaks in patients with CSF rhinorrhea and to study the potential long-term(More)
OBJECTS The goal of cerebral arteriovenous malformation (AVM) therapy in pediatric patients should be complete resection or obliteration of the AVM to eliminate subsequent hemorrhage, because of high mortality and morbidity rates related to hemorrhage in addition to the longer life expectation. Despite advances in Gamma knife radiosurgery and in(More)
BACKGROUND Risks related to rebleeding of a ruptured intracranial aneurysm have decreased. However, ischemic neurologic deficits related to vasospasm are still the leading causes of mortality and morbidity. It is well known that vasospasm is a dynamic process affected by various factors. The severity of vasospasm in animal models and clinical observations(More)
INTRODUCTION Hippocampal sclerosis is the most common lesion in patients with mesial temporal lobe epilepsy. Recently, there has been growing evidence on the involvement of mitochondria also in sporadic forms of epilepsy. In addition, it has been increasingly argued that mitochondrial dysfunction has an important role in epileptogenesis and seizure(More)
