Here, we present a case of pituitary adenoma producing adrenocorticotropic hormone (ACTH) in a 19-year-old woman. The patient was admitted to neurosurgery clinic because of a headache and decreased visual acuity. Transsphenoidal resection was performed. Microscopic examination of the tumor revealed signet-ring-like cell areas intermixed with conventional pituitary adenoma cells. Both populations of tumor cells showed immunoreactivity for chromogranin, synaptophysin, and ACTH. To date, there have been 3 reports of pituitary adenoma with signet-ring-like changes...

BACKGROUND: Blood vessel segmentation is a topic of high interest in medical image analysis since the analysis of vessels is crucial for diagnosis, treatment planning and execution, and evaluation of clinical outcomes in different fields, including laryngology, neurosurgery and ophthalmology. Automatic or semi-automatic vessel segmentation can support clinicians in performing these tasks. Different medical imaging techniques are currently used in clinical practice and an appropriate choice of the segmentation algorithm is mandatory to deal with the adopted imaging technique characteristics (e...

We present an analytical review of various neurosurgical interventions in conscious patients. An analysis of the literature indicates growing interest in this problem. Craniotomy in conscious patients has been extensively used in resection of space-occupying cerebral lesions in the eloquent hemispheric areas and in epilepsy surgery. In recent years, there have been a number of reports on interventions in conscious patients with other neurosurgical pathologies, which may be regarded as a new emerging tendency in neurosurgery and neuroanesthesiology...

BACKGROUND: Red blood cell (RBC) transfusion can be life-saving; however, the risks of RBC transfusion have been increasingly recognized, and current guidelines recommend restrictive transfusion in most patients. We hypothesized that RBC transfusions are decreasing in surgical patients. STUDY DESIGN AND METHODS: A retrospective review of the National Surgical Quality Improvement Program database was performed from 2011 to 2015. Index cases in five surgical specialties were studied: neurosurgery, thoracic surgery, gynecologic surgery, orthopedic surgery, and vascular surgery...

Background: There is not enough studies to determine the frequency of using the prophylaxis against deep venous thrombosis (DVT) based on the American College of Chest Physician's (ACCP) guidelines in Iran. Thus, providing such statistics is essential to improve thromboprophylaxis in hospital. The present study aimed to determine the frequency of using the prophylaxis against DVT based on ACCP guidelines in patients hospitalized in surgical wards in one of teaching hospital in Ilam, Iran...

OBJECTIVE: To review the intellectual history of concussion from the mid-19th century to the opening decade of the 21st century. BACKGROUND: Head injuries (HI) and their acute and long-term effects have been investigated for centuries, with major reviews of the topic appearing by 1870. Thus, while it has long been acknowledged that chronic traumatic encephalopathy was first described by Harrison Martland in 1928, an examination of the history of concussion research up to Martland's seminal report places his studies in a deeper historical context...

Since the introduction of cerebral bypass surgery by Professor Yasargil in 1967, a plethora of literature has been published on direct cerebral revascularization. Against this background, it is remarkable that at present, only three randomized controlled trials (RCTs) exist in the field, both dealing with extracranial to intracranial bypass surgery for flow augmentation in patients at risk to suffer ischemic or hemorrhagic stroke due to cerebrovascular disease. Next to flow augmentation, the other main indication for bypass surgery is to provide flow replacement following proximal vessel sacrifice for treatment of complex aneurysms or skull base tumors...

Neurosurgery is an under-utilised treatment that can potentially cure drug-refractory epilepsy. Careful, multidisciplinary pre-surgical evaluation is vital for selecting patients and ensure optimal outcomes. Advances in neuroimaging have improved diagnosis and guide surgical intervention. Invasive electroencephalography allows the evaluation of complex patients who would otherwise not be candidates for neurosurgery. We review the current state of the assessment and selection of patients and consider established and novel surgical procedures, and associated outcome data...

OBJECTIVE: Nowadays, the sitting position has lost favor among neurosurgeons partly due to assumptions of increased complications, such as venous air embolisms (VAEs) and hemodynamic disturbances. Moreover, it may oblige the surgeon to a tiring posture. Herein, we describe our protocol for the "praying (steeper sitting) position" for pineal region surgery, a variant which may reduce some of the risks of the sitting position while providing a more ergonomic surgical position...
