BACKGROUND: Spinal cord stimulation (SCS) is a common intervention for managing intractable pain. Generally, leads are implanted in a minimally invasive procedure with verbal feedback regarding the location and nature of generated paresthesias by active stimulation; in this way their optimal location can be confirmed. However, lead placement under general anesthesia can have additional benefits. OBJECTIVE: To investigate the outcomes of awake vs asleep lead placement procedures...

Introduction: To achieve the aim of zero preventable deaths on the battlefield a deeper understanding of uncontrolled hemorrhage from junctional or proximal extremity sources is mandatory. While tourniquet application to the extremities has drastically reduced morbidity and mortality, there is still room for improvement regarding the timing of tourniquet placement as the available evidence clearly points out a tight correlation between timing of tourniquet application and outcome. To save as many lives as possible the "point of no return" regarding the circulatory breakdown due to hemorrhage, colloquially addressed as platinum 5 min, needs to be determined...

Increasing access to early care and education (ECE) for children in the child welfare system (CWS) remains a critical issue in the United States, as the numbers of young children entering this system steadily increases. Mounting evidence suggests that participation in at least some types of ECE can mitigate the need for child welfare supervision. Moreover, ECE participation has been linked to positive developmental and school readiness outcomes, lower rates of foster placement, and greater placement stability for children in the CWS...

The case of a 27-year-old Hispanic female who presented with an occipito-parietal tumor after suffering trauma to the area. A physical examination revealed no tenderness to palpation and with evidence of healing ulcerations. The biopsy was consistent with a synovial sarcoma. A wide excision of the mass (15cm x 14cm x 6cm) followed by a pericranial flap was performed. A follow-up CT showed recurrence involving the parietal sagittal sinus. After a second biopsy the mass was determined to be a small-cell sarcoma, consistent with Ewing's sarcoma...

The recent discovery of two new species of kiwaid squat lobsters on hydrothermal vents in the Pacific Ocean and in the Pacific sector of the Southern Ocean has prompted a re-analysis of Kiwaid biogeographical history. Using a larger alignment with more fossil calibrated nodes than previously, we consider the precise relationship between Kiwaidae, Chirostylidae and Eumunididae within Chirostyloidea (Decapoda: Anomura) to be still unresolved at present. Additionally, the placement of both new species within a new "Bristly" clade along with the seep-associated Kiwa puravida is most parsimoniously interpreted as supporting a vent origin for the family, rather than a seep-to-vent progression...

OBJECTIVE Currently, there is no established standard regarding the ideal number of external ventricular drain (EVD) clamp trials performed before ventriculoperitoneal (VP) shunt insertion following nontraumatic subarachnoid hemorrhage (SAH). In this study, the authors aimed to evaluate this relationship. METHODS A retrospective review of all patients presenting with SAH between July 2007 and December 2016 was performed. Patients with SAH who had received an EVD within the first 24 hours of hospital admission and had undergone at least 1 clamp trial prior to EVD removal were eligible for inclusion in the study...

Skin necrosis overlying an arteriovenous fistula at the cannulation site is a common and potentially life-threatening problem, often associated with underlying aneurysm formation. Arteriovenous fistula-skin necrosis generally requires resection of surrounding skin margins and the underlying aneurysmal vessel wall, allowing repair with healthy tissue of the arteriovenous fistula in addition to closure of soft tissue and skin. In patients with insufficient fistula length, salvage of these arteriovenous fistulas may result in difficult or insurmountable cannulation issues leading to attempts at one-needle cannulation dialysis or, most often, catheter placement...

Intracranial gas is commonly detected on neuroimaging. The recognition of this finding can at first blush be unsettling. Being able to localize this gas to a specific compartment: intraarterial, intravenous, intraparenchymal, subdural, epidural, subarachnoid and intraventricular, is the first step in determining the importance of the gas. Determination of the route of entry: through the skull, extension from a paranasal sinus or the mastoid air cells, via the spine, or trans-vascular, is the other important factor in determining potential consequences...

BACKGROUND: The variety of diagnostic characteristics associated with neurocysticercosis have been well studied, however, its potential to be implicated in other differential diagnosis has not been well demonstrated. CASE DESCRIPTION: We report the case of a 55-year-old Hispanic man who underwent a Chiari decompression surgery, which was complicated with hydrocephalus. Despite a ventriculoperitoneal (VP) shunt placement, he continued to have headaches and was soon found to have several skull base subarachnoid lesions, which were later diagnosed as the sequelae of an active neurocysticercosis infection...

BACKGROUND: Aberrant medial retropharyngeal prevertebral course of internal carotid arteries (ICAs) is extremely uncommon. In oropharyngeal surgeries like trans oral odontoidectomy (TOO) this unrecognized aberrant retropharyngeal course of ICAs can result in devastating complications secondary to inadvertent injury of ICAs. Authors describe this aberrant course of ICAs in a patient with craniovertebral junction (CVJ) anomaly with dysmorphic C1 lateral mass on one side and discuss in detail various management issues in this complex case...

BACKGROUND: Up to 50% of patients receiving an artificial urinary sphincter (AUS) require surgical revision after initial placement. However, the literature is heterogeneous regarding the leading causes of AUS failure and appropriate surgical management. OBJECTIVE: To inform a revision approach by tabulating the causes of AUS failure, assessing AUS component survival, and examining the single-component revision efficacy. DESIGN, SETTING, AND PARTICIPANTS: We retrospectively reviewed 168 patients receiving AUS placements carried out by a single surgeon from 2008 to 2016 at a high-volume academic institution...

BACKGROUND: Health-related unemployment is a major issue across advanced economies. Modified versions of well-evidenced Individual Placement and Support (IPS) models of employment support for health cohorts offer considerable potential. A significant gap currently however is the lack of evidence around their financial return on investment. OBJECTIVE/HYPOTHESIS: To provide robust financial return on investment estimates for analytically derived alternative specifications of modified IPS services for the first time in the literature, sensitivity tested across various levels of performance...

BACKGROUND AND OBJECTIVE: While Minimally Invasive Surgery (MIS) offers considerable benefits to patients, it also imposes big challenges on a surgeon's performance due to well-known issues and restrictions associated with the field of view (FOV), hand-eye misalignment and disorientation, as well as the lack of stereoscopic depth perception in monocular endoscopy. Augmented Reality (AR) technology can help to overcome these limitations by augmenting the real scene with annotations, labels, tumour measurements or even a 3D reconstruction of anatomy structures at the target surgical locations...
