BACKGROUND: In Nigeria, maternal, newborn, and child health (MNCH) weeks are campaign-like events designed to accelerate progress toward Millennium Development Goals. The authors examined whether integrating HIV testing into MNCH weeks was feasible and could lead to increased case finding and linkage to prevention of mother-to-child transmission (PMTCT) services. METHODS: Pregnant women attending MNCH week during the first week of December 2014 in 13 local government areas in Benue State were provided with HIV tests and referrals to PMTCT services...

The global prevalence of depression is increasing, along with rates of depression-associated disability and mortality, rendering depressive disorders a major public health issue. Chronotherapy involves a variety of strategies that control exposure to environmental stimuli that influence the biological clock, such as sleep deprivation (SD) or wake therapy (WT), sleep phase advance (SPA), and light and dark therapy (LT, DT). The purpose of this Evidence-Based Practice (EBP) paper is to answer PICOT questions by a review the effectiveness of chronotherapeutics interventions on depressive symptoms with depression and the depressive episode in the course of bipolar disorder...

Background Type I Chiari malformation presents without an associated hydromyelia in 30 to 70% of cases, yet there is no agreement regarding the optimal surgical treatment for these patients. We review our experience for treating symptomatic adult type I Chiari malformation without hydromyelia using a suboccipital bone decompression of the hindbrain and no duraplasty in 12 adult patients. Outcome was measured according to the Chicago Chiari Outcome Scale (CCOS). Results Nine of 12 patients were female; average age at surgery was 34...

Hongpeng Li, Qin Zhang, Xiaohui Yang, Liping Wang
BACKGROUND: Secondary damage is often more important in determining the functional outcome and provides a practical target for therapeutic intervention. Rosiglitazone (ROSG) is a potent PPAR-γ agonist and has been shown to induce neuroprotection in animal models of spinal cord injury (SCI). However, it is still unclear whether this PPAR-γ agonist can mediate neuronal autophagy after SCI. METHODS: SCI was induced by application of vascular clips (force of 24g) to the dura via a four-level T5-T8 laminectomy...

BACKGROUND: Vertex epidural hematoma (VEH) is an uncommon presentation of extra-axial hematomas. It can represent a surgical dilemma regarding when and how to operate, particularly considering the potential implication of the superior sagittal sinus (SSS). OBJECTIVE: Here, we illustrate the surgical technique for VEH as well as review of the existing literature. METHODS: A 60-year-old male sustained a ground level fall resulting in complete diastasis of the sagittal suture with underlying large VEH causing significant mass effect on the SSS and bi-hemispheric convexities...

A multifunctional nanomedicine platform was designed and evaluated for efficient colon cancer therapy by a combinatorial therapeutic approach based on a chemotherapeutic drug and mild hyperthermia. Advantage was taken from the dual role of methotrexate (MTX), as folate receptor-targeting, overexpressed in tumor cells, and as anticancer drug. Incorporation of superparamagnetic iron oxide nanoparticles (SPIONs) allows to heat cancer cells externally through an alternating magnetic field. The developed nanocarrier was based on polyethylene glycol-polylactic acid (PEG-PLA) nanospheres to improve biocompatibility, enhancing their targeting by prolonging blood circulation time...

INTRODUCTION: Recent studies suggest that the human endolymphatic sac (ES) may have multiple functions, including an ion-transport capacity comparable to the kidney, an immunological capacity and a possible natriuretic capacity. Further, there have been speculations of a yet undefined role in intracranial pressure homeostasis. The anatomical location towards the sigmoid sinus would suggest a possible endo- and/or paracrine signaling. However, neuronal connections may also apply, but it remains very scarcely explored in the human ES...

Extradural hematoma (EDH) in absence of trauma is a rare entity with only few cases reported in literature. The various causes reported include: Vascular malformation of dura, coagulopathies, sinus infection, middle ear or orbital infection, and tumor. Occurrence of spontaneous EDH as a complication of sickle cell disease is even much rarer. We report a case with sickle cell disease who presented with spontaneous extradural and subgaleal hematomas following an episode of vaso-oclusive crisis. He was managed successfully with surgery...

O Fain, A Mekinian
Pachymeningitis is a fibrosing and inflammatory process, which involves the dura mater. Some pachymeningitis are cranial and induce headaches and cranial nerve palsies. Others are spinal and responsible for nerve roots or spinal cord compression. MRI shows contrast enhancement thickening of the dura mater. Etiologies are infectious (syphilis, tuberculosis, etc.) or inflammatory (sarcoidosis, granulomatosis with polyangiitis, IgG4-related disease, idiopathic). Corticosteroids are the main treatment. The use of immunosuppressive drugs or rituximab is yet to be determined and probably adapted to each etiology...

OBJECTIVE: The aim of this study was to analyze the prevalence of dental and jaw changes in individuals with sickle cell anemia (SCA) compared with a control group from a Brazilian population. STUDY DESIGN: This was a retrospective cross-sectional study. Participants were divided into 2 groups: SCA and control (123 patients per group). Intraoral periapical radiographs were taken. Changes in bone pattern and dental changes were investigated by using the following radiographic parameters: (1) trabecular bone (step-ladder or spider web); (2) integrity of the lamina dura (loss of sharpness and continuity, partial or complete absence, and increased thickness); and (3) dental changes (pulp chamber, root surface, periapex, dental form, number, and position)...

OBJECTIVE A fibrous structure located dorsal to the dura at the posterior craniocervical junction stretches horizontally between the bilateral occipital condyles and the upper borders of the C-1 laminae. Partially covered by the occipital bone, this structure is always encountered when the bone is removed from the foramen magnum rim during approaches to the posterior cranial fossa. Although known to surgeons, this structure has not been defined, studied, or named. The most appropriate name for this structure is "the suboccipital ligament," and a detailed rationale for this name is provided...

BACKGROUND: Microelectrode recording (MER) is used to confirm targeting accuracy during deep brain stimulation (DBS) surgery. We describe a technique using intraoperative CT extrapolation (iCTE) to predetermine and adjust the trajectory of the guide tube in order to improve microelectrode targeting accuracy. We hypothesized that this technique would decrease the number of MER tracks and operative time, while increasing the recorded length of subthalamic nucleus (STN). METHODS: Thirty-nine patients with Parkinson's disease who underwent STN DBS before the iCTE method were compared to 33 patients undergoing STN DBS using iCTE...

Various biomimetic scaffolds with hierarchical micro/nanostructures are designed to closely mimic native extracellular matrix network and to guide cell behavior to promote structural tissue generation. However, it remains a challenge to fabricate hierarchical micro/nanoscaled fibrous scaffolds with different functional components that endow the scaffolds with both biochemical and physical features to exert different biological roles during the process of tissue healing. In this study, a biomimetic designed micro/nanoscaled scaffold with integrated hierarchical dual fibrillar components is fabricated in order to repair dura mater and prevent the formation of epidural scars via collagen molecule self-assembly, electrospinning, and biological interface crosslinking strategies...

BACKGROUND: Tortuous and dolichoectatic vertebrobasilar arteries can impinge on the brainstem and cranial nerves to cause compression syndromes. Transposition techniques are often required to decompress the brainstem with dolichoectatic pathology. We describe our evolution of an anteromedial transposition technique and its efficacy in decompressing the brainstem and relieving symptoms. OBJECTIVE: To present the anteromedial vertebrobasilar artery transposition technique for macrovascular decompression of the brainstem and cranial nerves...

Three medium size constructed wetlands (CWs) with a total surface of 90ha are working since 2009 in the Albufera de Valencia Natural Park (Spain). Two of them are fed with eutrophic waters from l'Albufera Lake. Their objectives are both reduce the phytoplankton biomass and increase the biodiversity; consequently, improved water quality is returned to the lake. A "science based governance" of these CWs is ongoing inside the LIFE+12 Albufera Project to demonstrate the environmental benefits of these features...
