AIM: Trauma and diabetes with concomitant vascular pathologies are leading causes of limb amputations. Functionality following amputation procedures is very important for social re-integration of the patients. In this study, we aimed to learn how rat primary somatosensory cortex (pSSC) responses to the loss of inputs from hind-paw, using fMRI of an inferior magnetic power (1.5 Tesla) with special designed high-powered rat coil.

AIM: To compare the accuracy of determining pathologic segment between three-position MRI (3P-MRI) and post-myelographic CT (PMCT) in cervical spondylotic myelopathy (CSM) by assessing the degree of inter-observer and intra-observer agreement. MATERIAL AND METHODS: We retrospectively reviewed 3P-MRI and PMCT for the diagnosis of multilevel CSM in 136 patients who underwent surgery. Using an assessment scale, 8 blind observers with various clinical experiences examined 5 parameters: spinal canal narrowing, foraminal stenosis, bony abnormality, intervertebral disc herniation, and nerve root compression...

AIM: To compare the effect of long and short axonal lengths on neuromuscular neurotization (NMN). MATERIAL AND METHODS: In this study, 18 male Wistar rats were divided into two groups. In each group, the peroneal nerve and soleus muscle were dissected. In Group1, the muscle was neurotized after the peroneal nerve was dissected until bifurcation. In Group2, the nerve was transected 1 cm proximal from the most distal site, and the muscle was neurotized with a shorter nerve than that in Group1...

AIM: To investigate possible correlations between serum S100B levels and microglial/astrocytic activation in status epilepticus (SE) in lithium-pilocarpine-exposed rat hippocampi and whether serum S100B levels linearly reflect neuroinflammation. Additionally, to assess the effects of minocycline (M), an inhibitor of neuroinflammation. MATERIAL AND METHODS: Rats were divided into 4 groups (6/group), namely, control (C), sham, SE, and SE+M. Animals were exposed to lithium-pilocarpine to induce SE in the SE and SE+M groups...

AIM: Traumatic Brain Injury(TBI) is one of the leading causes of mortality. Vasoactive and inotropic drugs are commonly administered in these patients in case of hypotension. We aim to assess the feasibility of the Vasoactive-Inotropic Score(VIS) in determining the amount of vasoactive support and its relationship with the mortality rate. MATERIAL AND METHODS: Our study was conducted with a retrospective design involving the years 2013-2018 in a university hospital...

AIM: The aim of this study was to investigate the external anatomy of the fourth ventricle and dorsal brainstem using morphometric data, which could be useful for preoperative surgical planning. MATERIAL AND METHODS: Between January 2017 and December 2017, 42 fresh adult cadavers were investigated for the measurements of the cadaver brainstems and fourth ventricle, and they were recorded by photography. Measurements were evaluated according to body mass indexes(BMIs) of the patients...

AIM: Deep brain stimulation (DBS) of the subthalamic nucleus is a preferred option for the treatment of motor symptoms in patients with Parkinson\'s disease (PD). Intraoperative microelectrode recording (MER), which guides the implantation of the DBS lead, can induce a microlesion effect (MLE) that results in motor symptom improvement. Although this phenomenon is well known, its quantitative impact remains unknown. In this prospective study, we investigated MER-induced MLE on the motor symptoms of 30 patients with PD...

AIM: In glioblastoma multiforme, the balance between the procoagulant system, anticoagulant system and fibrinolytic system is impaired in favour of hypercoagulability. The aim of this study was to compare glioblastoma multiforme with astrocytoma grade II by subjectively evaluating the levels of prothrombin and biotinylation thrombin, and G protein serum protease activatin receptors, as tissue factors causing hypercoagulation and affecting coagulation. MATERIAL AND METHODS: Specimens from 35 cases with glioblastoma multiforme and 23 cases with astrocytoma grade II were evaluated immunohistochemically...

AIM: Hydrocephalus is characterized by enlargement of the cerebral ventricles, leading to increased intracranial pressure and consequent motor, cognitive, and endocrine disturbances. Herein, we demonstrate progression of acute and chronic endocrinopathy in a kaolin-induced hydrocephalus model using light microscopy. MATERIAL AND METHODS: Adult male Sprague-Dawley rats (n = 48) were divided into six groups. Hydrocephalus was induced by intracisternal injection of kaolin solution in the acute and kaolin groups, whereas an identical volume of sterile saline was injected into the sham groups...

AIM: Lumbar disc herniation is a common disease and can cause back pain and radicular pain. Some cases require surgical intervention for persistent severe pain. In other cases, transforaminal epidural steroid injection is the treatment of choice. This study compared the outcomes of fluoroscopically guided transforaminal epidural steroid injections of L4-L5 paramedian disc herniation with L5-S1 paramedian disc herniation for the treatment of radicular pain. MATERIAL AND METHODS: A total of 593 patients treated by transforaminal epidural steroid injections for the treatment of L4-5 paramedian disc herniation and 504 patients treated by transforaminal epidural steroid injections for the treatment of L5-S1 paramedian disc herniation were included in the study...

AIM: There is no consensus in the literature regarding the optimal method of obtaining cerebrospinal fluid sample in patients with suspected shunt infections. The most frequently used method is tapping shunt reservoir. Lumbar puncture is an alternative method yet it used far less frequently. MATERIAL AND METHODS: Medical records of pediatric patients with suspected shunt infections were retrospectively analyzed. All patients had cerebrospinal fluid samples obtained either via shunt tapping, lumbar puncture or both...

AIM: We report the four most common spinal parasites to provide insight into definitive therapy. MATERIAL AND METHODS: Twelve patients with spinal parasites were diagnosed between 2009 and 2016. A definite diagnosis was established in the form of histopathology (n=9) and response to drug therapy (n=3). The minimum follow-up was 1.0 years and ranged to a maximum of 7 years, with a median of 3.4 years.

Strongyloidiasis is an infestation caused by the intestinal nematode Strongyloides stercoralis. It is potentially fatal in immuno-compromised hosts due to its capacity to cause an overwhelming hyperinfestation however infested healthy individuals are usually asymptomatic. Hyperinfestation is extremely rare in the Central Nervous System (CNS) and usually limited to the gastrointestinal tract or lungs. CNS involvement in strongyloidiasis has only been seen in patients with hyperinfestation syndrome and may be fatal when misdiagnosed...
