Patients who are stationary endure prolonged soft tissue distortions and deformations at contact areas between their body and the support surface, which may lead to the onset of pressure ulcers (PUs) over time. A novel technology for patient positioning employs innovation in materials science, specifically viscoelastic materials with shape memory properties that compose the Z-Flo™ head positioner (Mölnlycke Health Care, Gothenburg, Sweden). Head positioners are generally known to reduce the occurrence of PUs in scalp tissues and the ears, but quantitative assessments of their biomechanical efficacy are missing in the literature...

The uneven distributed microstructure featured with plate-like spongy bone in woodpecker's skull has been found to further help reduce the impact during woodpecker's pecking behavior. Therefore, this work was to investigate the micro-mechanical properties and composition on different sites of Great Spotted woodpecker's (GSW) skull. Different sites were selected on forehead, tempus and occiput, which were also compared with those of Eurasian Hoopoe (EH) and Lark birds (LB). Micro structural parameters assessed from micro computed tomography (μCT) occurred significantly difference between GSW, EH and LB...

REVIEW
Rachel A Pilliod, Aaron B Caughey
Fetal malpresentation and fetal malposition are frequently interchanged; however, fetal malpresentation refers to a fetus with a fetal part other than the head engaging the maternal pelvis. Fetal malposition in labor includes occiput posterior and occiput transverse positions. Both fetal malposition and malpresentation are associated with significant maternal and neonatal morbidity, which have significant impact on patients and providers. Accurate diagnosis of both conditions is necessary for appropriate management...

OBJECTIVE Because of limitations inherent to cadaver models of endotracheal intubation, the authors' group developed a finite element (FE) model of the human cervical spine and spinal cord. Their aims were to 1) compare FE model predictions of intervertebral motion during intubation with intervertebral motion measured in patients with intact cervical spines and in cadavers with spine injuries at C-2 and C3-4 and 2) estimate spinal cord strains during intubation under these conditions. METHODS The FE model was designed to replicate the properties of an intact (stable) spine in patients, C-2 injury (Type II odontoid fracture), and a severe C3-4 distractive-flexion injury from prior cadaver studies...

Chronic deafferentations in adult mammals result in reorganization of the brain. Lesions of the dorsal columns of the spinal cord at cervical levels in monkeys result in expansion of the intact chin inputs into the deafferented hand representation in area 3b, second somatosensory (S2) and parietal ventral (PV) areas of the somatosensory cortex, ventroposterior lateral nucleus (VPL) of the thalamus, and cuneate nucleus of the brainstem. Here, we describe the extent and nature of reorganization of the cuneate and gracile nuclei of adult macaque monkeys with chronic unilateral lesions of the dorsal columns, and compare it with the reorganization of area 3b in the same monkeys...

OBJECTIVE: To describe a new technique for the reconstruction of parieto-occipital skull deformities. METHODS AND RESULTS: The technique is a variant of the previously described "cathedral dome procedure" used for frontal skull deformities. The authors apply the same principle of remodeling by making meridional slat craniotomies surrounding the depressed dome of the posterior skull deformity, followed by "green-stick fracture-reshaping" of the meridional slats to elevate and support the excised depressed dome...

This is a report on a 32-year-old man with a history of two previous melanomas with concurrent plaque-type psoriasis. His history dates to 2009, when he was diagnosed with his first melanoma on the right occiput, Clark's level IV, tumor thickness 1.53 mm, nonulcerated, mitotic index 1/mm2. He subsequently developed nodal recurrence after an initial negative sentinel lymph node biopsy and was treated with complete lymph node dissection. In 2012, he was diagnosed with a second primary melanoma on the right upper chest, Clark's level IV, tumor thickness 0...

Background Transcranial static magnetic field stimulation (tSMS) reduces cortical excitability in humans. Methods The objective of this study was to determine whether tSMS over the occipital cortex is effective in reducing experimental photophobia. In a sham-controlled double-blind crossover study, tSMS (or sham) was applied for 10 minutes with a cylindrical magnet on the occiput of 20 healthy subjects. We assessed subjective discomfort induced by low-intensity and high-intensity visual stimuli presented in a dark room before, during and after tSMS (or sham)...

Alopecic and aseptic nodules of the scalp (AANS) is a rare entity, etiology of which is already unknown. It consists of a few dome-shaped, skin-colored nodules associated with nonscarring alopecia. They are usually located in the upper part of the occiput and surrounded by normal scalp. Most of the times, a biopsy is performed to make an accurate diagnosis. AANS have a good prognosis and even can resolve spontaneously. We present a new case of this entity with the description of trichoscopic and ultrasonographic findings that have recently been reported...

OBJECTIVE The long-term effects of instrumentation and fusion of the occipital-cervical-thoracic spine on spinal growth in young children are poorly understood. To mitigate the effects of this surgery on the growing pediatric spine, the authors report a novel technique used in 4 children with severe cervical-thoracic instability. These patients underwent instrumentation from the occiput to the upper thoracic region for stabilization, but without bone graft at the craniovertebral junction (CVJ). Subsequent surgery was then performed to remove the occipital instrumentation, thereby allowing further growth and increased motion across the CVJ...

Extant rhinoceroses share the characteristic nasal horn, although the number and size of horns varies among the five species. Although all species are herbivores, their dietary preferences, occipital shapes, and common head postures vary. Traditionally, to predict the "usual" head posture (the most used head posture of animals during normal unstressed activities, i.e., standing) of rhinos, the occipital shape was used. While a backward inclined occiput implies a downward hanging head (often found in grazers), a forward inclined occiput is related to the horizontal head posture in browsing rhinos...

INTRODUCTION: Spondyloarthropathies (SpA) are disabling diseases with a prevalence of 1.9% in the general population. The indices designed for monitoring the disease should be valid, reliable and cross-culturally adapted for decision-making concerning the appropriate treatment. Changing an adjective or pronoun in a self-administered questionnaire could be the big difference in condensing an idea in a few words and transmitting that concept to all those who share the same language. OBJECTIVES: To develop a Venezuelan version of the original English version of the BASDAI/BASFI and to evaluate its reliability and validity in Venezuelan patients with SpA...

BACKGROUND: Split-thickness skin grafts are commonly used in dermatosurgery. For occipital donor sites, retrospective studies have shown good results with respect to graft take and healing rates. Nevertheless, the majority of grafts in dermatosurgery are harvested from the thigh. To date, there has been no prospective randomized controlled study comparing occipital versus femoral donor sites. PATIENTS AND METHODS: Following micrographically controlled R0 tumor resection, 108 patients were randomized prior to undergoing split-thickness skin grafting (donor site: occiput vs...
