Case summary: A 3-month-old intact male Somali cat was evaluated for a history of seizures, hypoglycaemia and mental dullness 4 weeks after being bitten in the head by a dog. The cat's body size and weight were approximately half that of his littermates and its haircoat was woolly, with fewer guard hairs. Multiple hypoglycaemic episodes were documented over a period of 4 weeks, which resolved rapidly after correction of the hypoglycaemia. Juvenile hyposomatotropism was presumptively diagnosed by demonstrating low circulating levels of insulin-like growth factor 1 and after exclusion of other endocrine and non-endocrine causes of small stature and hypoglycaemia...

Case summary: A 12-year-old neutered male domestic shorthair cat was presented to our referral hospital with a chronic history of tenesmus and lumbosacral pain. A diagnosis of degenerative lumbosacral stenosis (DLSS) was made and a standard dorsal L7-S1 laminectomy was performed uneventfully, with complete recovery within 1 month. The cat was brought back 4 months later for investigation of lumbosacral pain after having suffered a minor traumatic event. Neurological examination identified a low tail carriage, weakness, exercise intolerance, left pelvic limb lameness and diminished withdrawal reflexes in both pelvic limbs with severe sacrocaudal pain...

PURPOSE: Head trauma is common in the emergency department. Identifying the few patients with serious injuries is time consuming and leads to many computerized tomographies (CTs). Reducing the number of CTs would reduce cost and radiation. The aim of this study was to evaluate the characteristics of adults with head trauma over a 1-year period to identify clinical features predicting intracranial hemorrhage. METHODS: Medical record data have been collected retrospectively in adult patients with traumatic brain injury...

OBJECTIVE Aggressive dural arteriovenous fistulas (dAVFs) with cortical venous drainage (CVD) are known for their relatively high risk of recurrent neurological events or hemorrhage. However, recent natural history literature has indicated that nonaggressive dAVFs with CVD have a significantly lower prospective risk of hemorrhage. These nonaggressive dAVFs are typically diagnosed because of symptomatic headache, pulsatile tinnitus, or ocular symptoms, as in low-risk dAVFs. Therefore, the viability of stereotactic radiosurgery (SRS) as a treatment for this lesion subclass should be investigated...

Objectives: Impulse control disorders (ICDs) are common among patients with Parkinson's disease (PD). Risk factors identified for developing ICDs include young age, family history, and impulsive personality traits. However, the association of these potentially disabling disorders with nondopaminergic drugs and sleep disorders has been understudied. Our objective was to examine the association between ICDs and nondopaminergic medications and sleep disorders. Methods: We conducted an observational study of 53 patients with PD from the National Institute of Neurology and Neurosurgery...

BACKGROUND: The pathogenesis of osmotic demyelination syndrome is not completely understood and usually occurs with severe and prolonged hyponatremia, particularly with rapid correction. It can occur even in normonatremic patients, especially who have risk factors like alcoholism, malnutrition and liver disease. Bilateral tongue fasciculations with denervation pattern in electromyogram is a manifestation of damage to the hypoglossal nucleus or hypoglossal nerves. Tongue fasciculations were reported rarely in some cases of osmotic demyelination syndrome, but the exact mechanism is not explained...

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...

Within the context of a globalising agenda for genetic research where 'global health' is increasingly seen as necessarily informed by and having to account for genomics, the focus on rare genetic diseases is becoming prominent. Drawing from ethnographic research carried out separately by both authors in Brazil, this paper examines how an emerging focus on two different arenas of rare genetic disease, cancer genetics and a class of degenerative neurological diseases known as Ataxias, is subject to and a product of the dynamics of inclusion and exclusion as this concerns participation in research and access to health care...

BACKGROUND: This study aimed to describe the pathological findings and to analyze clinical predictors of abnormal imaging findings in patients presenting to the emergency department (ED) with syncope. METHODS: The database was retrospectively reviewed for all patients who underwent cranial computed tomography (CT) or magnetic resonance imaging (MRI), having the symptom of syncope. Patients were included only if they were from the emergency department and excluded if were under 18 years of age, had known recent intracranial pathology, known brain tumor, or having a history of trauma...

BACKGROUND: The headache preceding an intracranial aneurysm (AN) rupture is called a sentinel headache (SH), and it is characterized by a sudden, intense, and persistent headache. As subarachnoid hemorrhage (SAH) often develops within several weeks of SH, its rapid diagnosis and treatment can improve the prognosis. CASE DESCRIPTION: A 52-year-old woman with migraine in her medical history visited the outpatient clinic due to left orbital pain. There was no neurological deficit...

PURPOSE: Otogenic lateral sinus thrombosis (OLST) is an intracranial, potentially life-threatening complication of acute and chronic otitis media. Since congenital thrombophilic disorders are risk factors for cerebral venous thrombosis, OLST may be related to thrombophilia. The aim of our study was twofold: to evaluate whether patients who suffered from OLST in childhood also have thrombophilia, and whether these patients experienced thromboembolic episodes in future years. STUDY DESIGN: Retrospective case series...

INTRODUCTION: Numerous polymorphisms in candidate genes coding for haemostatic system proteins have been proposed as risk factors for thrombosis. METHODS: We performed a case-control study of consecutive ischaemic stroke survivors aged ≤ 45 years, treated at our neurology department from 2006 to 2014. Polymerase chain reaction-restriction fragment length polymorphism identified the following polymorphisms: Thr325Ile and Ala147Thr in TAFI, 4G/5G in PAI-1, PLA1/A2 in platelet glycoprotein IIb/IIIa, Glu298Asp in eNOS, and C677T in 5,10-MTHFR...
