Comparison of safety and stability of C-2 pars and pedicle screws for atlantoaxial fusion: meta-analysis and review of the literature.
Conclusions With a thorough knowledge of axis anatomy, surgeons can place both C-2 pars and C-2 pedicle screws accurately with a small risk of VA injury or clinically significant malposition. There may be subtle trade-off of safety for rigidity when using axial pedicle instead of pars screws, and the decision to use either screw type must be made only after careful review of the preoperative CT imaging and must take into account the surgeon's expertise and the particular demands of the clinical scenario in any given case.

PET imaging of the brain serotonin transporters (SERT) with N,N-dimethyl-2-(2-amino-4-[18F]fluorophenylthio)benzylamine (4-[18F]-ADAM) in humans: a preliminary study
Conclusion The results of this study showed that 4-[18F]-ADAM was safe for human studies and its distribution in human brain appeared to correlate well with the known distribution of SERT in the human brain. In addition, it had high specific binding and a reasonable optimal time for imaging brain SERT in humans. Thus, 4-[18F]-ADAM may be feasible for assessing the status of brain SERT in humans.

Visibility of mandibular canal on panoramic radiograph after bilateral sagittal split osteotomy (BSSO)
Conclusions The visibility of the MC decreased immediately after BSSO, especially at the operation site (M2 and M1), while maximum MC visibility was achieved at 12 months postoperatively in our series. Since MC was not visible at the operation site after BSSO for 50 % of the subjects, it may be necessary to use additional visualization modalities for postoperative patient assessment in this region.

Organization of the neural switching circuitry underlying reflex micturition
Abstract The functions of the lower urinary tract to store and periodically eliminate urine are regulated by a complex neural control system in the brain and spinal cord that coordinates the activity of the bladder and urethral outlet. Experimental studies in animals indicate that urine storage is modulated by reflex mechanisms in the spinal cord, whereas voiding is mediated by a spinobulbospinal pathway passing through a coordination center in the rostral brain stem. Many of the neural circuits controlling micturition exhibit switch‐like patterns of activity that turn on and off in an all‐or‐none manner. This paper ...

A test of the Whitaker scoring system for estimating age from the bones of the foot
Abstract Within the literature pertaining to skeletal age estimation, there is a paucity of statistically validated methods of age estimation from the foot. Given the prevalence of recovery of pedal elements in isolation, it is critical that methods exist to facilitate the estimation of age from this anatomical region and that those methods be tested to ensure they are reliable, repeatable and statistically robust. A study was carried out to determine the validity of using the Whitaker method of age estimation from the bones of the foot as a tool in forensic age estimation within a modern Scottish population...

Fast rearrangement of the neuronal growth cone’s actin cytoskeleton following VEGF stimulation
Abstract The neuronal growth cone plays a crucial role in the development of the nervous system. This highly motile structure leads the axon to its final destination by translating guidance cues into cytoskeletal rearrangements. Recently, vascular endothelial growth factor (VEGF), which is essential for angiogenesis and vascular sprouting, has been found to exert a trophic activity also on neurons, leading to an increased axonal outgrowth, similar to the well-known nerve growth factor (NGF). The neurotrophic properties of VEGF are likely to be promoted via the VEGF receptor 2 (VEGFR-2) and neuropilin-1 (NRP-...

Expression and localization of nodal in bovine oviduct and uterus during different functional stages of oestrus cycle and pregnancy
Abstract Members of TGF-β superfamily play a major role in the endometrial changes involved in the establishment and maintenance of pregnancy. Their deregulated expression and action could lead to absolute or partial failure of embryo implantation. Nonetheless, the precise function and mechanism of many of these cytokines remain unclear. Nodal, a transforming growth factor beta (TGF-β) superfamily member, was characterized in the human and rodent uterus and implicated in the tissue remodeling events during menstruation and embryo implantation. In order to study its possible role in the cattle reproductive ...

Automatic Retrieval of Bone Fracture Knowledge Using Natural Language Processing
Abstract Natural language processing (NLP) techniques to extract data from unstructured text into formal computer representations are valuable for creating robust, scalable methods to mine data in medical documents and radiology reports. As voice recognition (VR) becomes more prevalent in radiology practice, there is opportunity for implementing NLP in real time for decision-support applications such as context-aware information retrieval. For example, as the radiologist dictates a report, an NLP algorithm can extract concepts from the text and retrieve relevant classification or diagnosis criteria or calcul...

The Retinotopic Organization of Striate Cortex Is Well Predicted by Surface Topology.
Abstract In 1918, Gordon Holmes combined observations of visual-field scotomas across brain-lesioned soldiers to produce a schematic map of the projection of the visual field upon the striate cortex . One limit to the precision of his result, and the mapping of anatomy to retinotopy generally, is the substantial individual variation in the size [2, 3], volumetric position , and cortical magnification  of area V1. When viewed within the context of the curvature of the cortical surface, however, the boundaries of striate cortex fall at a consistent location across individuals . We asked whether the surfac...

Assessment of collateral circulation to the hand prior to radial artery harvest
Assessment of collateral circulation to the hand is required prior to invasive procedures or harvesting of the radial artery (RA). A modified Allen’s test (MAT) is commonly used to assess palmar arch collaterals. A variety of non-invasive methods including digital pressures, plethysmography, pulse oximetry and duplex ultrasonography are available to supplement physical examination. However, no consensus exists about the proper role of the MAT and the most appropriate non-invasive test (NIT) in this situation. Interpretation of the MAT and NIT findings are also controversial.

Collagen hydrogels strengthened by biodegradable meshes are a basis for dermo‐epidermal skin grafts intended to reconstitute human skin in a one‐step surgical intervention
This study aimed to test novel dermo‐epidermal skin substitutes based on collagen type I hydrogels, physically strengthened by two types of polymeric net‐like meshes. One mesh has already been used in clinical trials for treating inguinal hernia; the second one is new but consists of a FDA‐approved polymer. Both meshes were integrated into collagen type I hydrogels and dermo‐epidermal skin substitutes were generated. Skin substitutes were transplanted onto immuno‐incompetent rats and analyzed after distinct time periods. The skin substitutes homogeneously developed into a well‐stratified epidermis over the enti...

(iv) Elbow instability
Abstract: Acute elbow instability ranges from simple dislocations without significant fractures to complex dislocations involving fractures of the coronoid and radial head (“terrible triad”). Simple dislocations for the most part are stable after reduction, managed with early mobilisation and have good outcomes with relatively low complication rates. In contrast, complex fracture-dislocations render the elbow very unstable and therefore surgical intervention is usually necessary to restore bony and ligamentous stability to allow early range of motion. The risk of complications, including stiffness, chronic instability,...

'Fibre Body': The Concept of Fibre in Eighteenth-century Medicine, c.1700-40(1).
Abstract This paper attempts a comprehensive account of 'fibre medicine' elaborated by iatromechanists from c. 1700 to c. 1740. Fibre medicine, a medical theory informed by the notion of the fibre, has been neglected by medical historians despite the pivotal role played by the fibre in animal economy. Referring to a wide range of medical fields such as anatomy, physiology, pathology, therapeutics and life sciences, this paper elucidates the ways that the fibre serves as an indispensable concept for iatromechanists to establish their medical theories. This paper also highlights the metaphorical dimension of the fibr...

A review of the anatomical, biomechanical and kinematic findings of posterior cruciate ligament injury with respect to non-operative management
Abstract: An understanding of the kinematics of posterior cruciate ligament (PCL) deficiency is important for the diagnosis and management of patients with isolated PCL injury. The kinematics of PCL injury has been analysed through cadaveric and in vivo imaging studies. Cadaveric studies have detailed the anatomy of the PCL. It consists of two functional bundles, anterolateral and posteromedial, which exhibit different tensioning patterns through the arc of knee flexion. Isolated sectioning of the PCL and its related structures in cadaveric specimens has defined its primary and secondary restraining functions. The PCL is t...

Valve replacement in children: A challenge for a whole life.
Abstract Valvular pathology in infants and children poses numerous challenges to the paediatric cardiac surgeon. Without question, valvular repair is the goal of intervention because restoration of valvular anatomy and physiology using native tissue allows for growth and a potentially better long-term outcome. When reconstruction fails or is not feasible, valve replacement becomes inevitable. Which valve for which position is controversial. Homograft and bioprosthetic valves achieve superior haemodynamic results initially but at the cost of accelerated degeneration. Small patient size and the risk of thromboembolis...

Ontogenetic and Structural Variation of Mineralizations and Ossifications in the Integument within Ceratophryid Frogs (Anura, Ceratophryidae)
We describe the ontogeny of the integument in the three genera of ceratophryids (Chacophrys, Ceratophrys, and Lepidobatrachus) that inhabit in semiarid environments. Data obtained demonstrated the early acquisition of metamorphic transformations in the integument layers in larvae of Ceratophrys cranwelli and Lepidobatrachus spp. and a continuous increment in the thickness of them up to old postmetamorphic stages. The integument of ceratophryids develops calcium deposits as the calcified layer during postmetamorphic stages. Furthermore, dorsal shields are also present in adult stages independently of terrestrial versus aqua...

Evaluation of normal fetal pulmonary veins using B‐flow imaging with spatiotemporal image correlation and by traditional color Doppler echocardiography
ConclusionsThe scanning around left atrium method proved to be the most suited for detecting pulmonary veins in clinical practice. 4D BF‐STIC was superior in detecting the greatest number of pulmonary veins before 32 gestational weeks, but had limited clinical usage because it was very time‐consuming and experience‐dependent. The 4D method should be considered as a complement to traditional two‐dimensional sonography, because it facilitates understanding of the anatomy and the spatial relationships of the cardiac structures. © 2012 John Wiley & Sons, Ltd.

Ulnar tunnel syndrome.
Abstract Ulnar tunnel syndrome could be broadly defined as a compressive neuropathy of the ulnar nerve at the level of the wrist. The ulnar tunnel, or Guyon's canal, has a complex and variable anatomy. Various factors may precipitate the onset of ulnar tunnel syndrome. Patient presentation depends on the anatomic zone of ulnar nerve compression: zone I compression, motor and sensory signs and symptoms; zone II compression, isolated motor deficits; and zone III compression; purely sensory deficits. Conservative treatment such as activity modification may be helpful, but often, surgical exploration of the ulnar tunne...

Laparoscopic Transgastric Endoscopy after Roux-en-Y Gastric Bypass: Case Series and Review of the Literature.
We describe a case series of 13 patients with a history of Roux-en-Y gastric bypass for the treatment of morbid obesity who underwent laparoscopic transgastric endoscopy through the gastric remnant to access the duodenum or biliary tree. Charts of these patients were reviewed for demographics, indications for procedure, length of stay, morbidity, and mortality. Four of the patients had failed prior attempts to access the excluded anatomy through traditional transoral endoscopy. Two patients underwent transgastric endoscopy for evaluation of gastrointestinal bleeding. Of the 11 patients for whom endoscopic retrograde cholan...

Pancreatic fluid collections: Physiology, natural history, and indications for drainage
Abstract: Pancreatic fluid collections (PFCs) are a common manifestation of pancreatitis and can be seen in up to 50% of cases. Advances in cross-sectional imaging techniques have led to a greater understanding of the natural history of PFCs. This, combined with a lack of uniformity in the nomenclature of PFCs, has led to the revised Atlanta Criteria for pancreatic fluid collections, which designates 4 main types: acute peri-PFC (APFC), postnecrotic PFC (PNPFC), pancreatic pseudocyst, and walled-off pancreatic necrosis (WOPN). Each of these fluid collections can be either sterile or infected. When present for >4 weeks fro...
