Amy Voedisch, Michele Hugin
PURPOSE OF REVIEW: Subdermal contraceptive implant insertions have rapidly increased worldwide. These devices are usually removed 3-5 years after insertion. Although removals are generally straightforward, difficult removals can occur. This review discusses the overall approach to potentially problematic removals and the appropriate steps to avoid complications and safely remove implants. RECENT FINDINGS: Given the rapid uptake of contraceptive implants and subsequent need for removals, an Implants Removal Task Force was formed to create standard protocols for difficult implant removals worldwide...

REVIEW
Atsushi Mizuma, Midori A Yenari
While the mainstay of acute stroke treatment includes revascularization via recombinant tissue plasminogen activator or mechanical thrombectomy, only a minority of stroke patients are eligible for treatment, as delayed treatment can lead to worsened outcome. This worsened outcome at the experimental level has been attributed to an entity known as reperfusion injury (R/I). R/I is occurred when revascularization is delayed after critical brain and vascular injury has occurred, so that when oxygenated blood is restored, ischemic damage is increased, rather than decreased...

BACKGROUND: Incontinentia pigmenti is a rare X-linked dominant syndrome caused by mutation in the NEMO/IKKgamma gene, and characterized by a spectrum of cutaneous, ocular, neurologic and dental abnormalities. In the eye, findings include retinal vascular non-perfusion, occasionally with traction retinal detachment, retinal fibrosis, and retinal pigment epithelium defects. These findings can resemble retinoblastoma, especially when vitreoretinal fibrosis produces leukocoria. CASE REPORT: A 2-month-old girl born full-term presented with leukocoria, suspicious for retinoblastoma...

BACKGROUND: The most feared complications following endoscopic endonasal skull base surgery are arterial vascular injuries. Previously published literature is restricted to internal carotid artery injuries. The ideal method for controlling arterial bleeding during this kind of procedure is debated, and a variety of techniques have been advocated. OBJECTIVE: To evaluate the management and outcome following intraoperative arterial injury during endoscopic endonasal skull base surgery...

Platelets, anucleated megakaryocyte-derived cells, play a major role in hemostasis and arterial thrombosis. While protein kinase Casein Kinase 2 (CK2) is readily detected in megakaryocytes and platelets, the impact of CK2-dependent signaling on megakaryocyte/platelet (patho-) physiology has remained elusive. The present study explored the impact of the CK2 regulatory β-subunit on platelet biogenesis and activation. Megakaryocyte/platelet-specific genetic deletion of CK2β (ck2β(-/-) ) in mice resulted in a significant macrothrombocytopenia and an increased extramedullar megakaryopoiesis with enhanced proportion of premature platelets...

Background: Thrombospondin-1 (TSP-1) is an extracellular matrix protein that plays multiple physiological and pathophysiological roles in the brain. Experimental reports suggest that TSP-1 may have an adverse role in neuronal function recovery under certain injury conditions. However, the roles of TSP-1 in traumatic brain injury (TBI) have not been elucidated. In this study we for the first time investigated the roles of TSP-1 in a controlled cortical impact (CCI) model of TBI in TSP-1 knockout (TSP-1 KO) and wild type (WT) mice...

Penetrating head injuries are extremely rare in Japan. The authors describe a case involving a penetrating head injury from an arrow fired from a crossbow. A 52-year-old man who had shot himself transorally in a suicide attempt was admitted to the authors' hospital. On admission, he was conscious and exhibited no neurological deficits. The end of the arrow was visible inside his oral cavity. Computed tomography revealed the arrow had penetrated the right cerebellum and occipital lobe, resulting in a very small hematoma...

We report the case of a 56-year-old woman who underwent total resection of a Masson's tumor or intravascular papillary endothelial hyperplasia (IPEH), which was discovered due to a left temporal intracerebral hematoma revealed by aphasia. IPEH is more often localized on cutaneous and subcutaneous locations, intracranial IPEH are rare and only approximately twenty cases have been published to date. These tumors are a benign vascular lesion composed of papillary intravascular proliferation of epithelial cellular associated thrombosis with fibrin deposits responsible for vascular lumen obliteration...

BACKGROUND AND PURPOSE: There is a paucity of data on persistence of secondary prevention medications among stroke survivors in resource-limited settings where stroke is on a rapid upward trajectory and its management severely challenged. To avert new cardiovascular events after stroke, preventive medications should be promptly instituted and used continuously. We report 1-year rates and determinants of persistent utilization of secondary prevention therapies after stroke in Ghana. METHODS: A retrospective observational study involving 418 stroke survivors enrolled into a Neurology clinic in a tertiary institution in central Ghana between January 2011 and December 2013...

OBJECTIVE/BACKGROUND: The first paper in this series observed that pre-operative baroreceptor dysfunction and poorly controlled hypertension were independently predictive for identifying patients who went on to require treatment for post-endarterectomy hypertension (PEH). The second paper examines the influence of intra-operative patient, transcranial Doppler (TCD) ultrasound, and anaesthetic variables on the incidence of PEH. METHODS: In total, 106 patients underwent carotid endarterectomy (CEA) under general anaesthesia...

Migraine has been reported as a risk factor for ischemic stroke or cardiovascular events, and dysfunction of endothelial cells has been evidenced in migraine patients. Proangiogenic factors are potential endothelial stimulators, and their disturbances can link abnormalities of endothelium with increased risk of vascular disorders. The aim of this study was to evaluate the levels of circulating proangiogenic factors in sera of migraineurs during interictal period. Fifty-two patients aged 37.9 ± 9.6 years, fulfilling International Headache Society criteria for migraine, were included in this observational case-control study...

Neurovascular surgery is a broad and challenging, yet exciting field within neurologic surgery. The neurovascular surgeon must be meticulous; because the brain and spinal cord are unforgiving to ischemic insults. Along with the pressures of this demanding subspecialty comes the potential to help patients recover from potentially devastating pathology to go on and lead normal, healthy lives. Several intraoperative imaging modalities are available to help maximize treatment success while reducing risk. This article reviews each of these modalities, including digital subtraction angiography, fluorescence angiography, Doppler ultrasonography, laser Doppler, laser speckle contrast imaging, neuronavigation, and neuroendoscopy...

Spinal dural arteriovenous fistulas (SDAVFs) are the most common vascular malformation of the spinal cord, causing segmental lesions of the spinal cord due to venous ischemia. Functional outcomes of treatment in SDAVF patients are favorable, but the rate of improvement varies from 25 to 100%, which complicates prediction of the treatment outcome. AIM: the study aim was to identify a relationship between fistula localization and clinical manifestations and evaluate the effect of disease duration and severity of neurological impairments on immediate and long-term treatment outcomes, based on analysis of the literature and own data...

Circadian rhythm disturbances are well-established in neurological diseases. However, how these disruptions cause homeostatic imbalances remains poorly understood. Brain and muscle aryl hydrocarbon receptor nuclear translocator-like protein 1 (Bmal1) is a major circadian clock transcriptional activator, and Bmal1 deficiency in male Bmal1nestin(-/-) mice induced marked astroglial activation without affecting the number of astrocytes in the brain and spinal cord. Bmal1 deletion caused blood-brain barrier (BBB) hyperpermeability with an age-dependent loss of pericyte coverage of blood vessels in the brain...

Ischemic stroke is one of the leading causes of human death and disability worldwide. So far, ultra-early thrombolytic therapy is the most effective treatment. However, most patients still live with varying degrees of neurological dysfunction due to its narrow therapeutic time window. It has been confirmed in many studies that endothelial progenitor cells (EPCs), as a kind of adult stem cells, can protect the neurovascular unit by repairing the vascular endothelium and its secretory function, which contribute to the recovery of neurological function after an ischemic stroke...
