Iron is a 'one-way' element and the primary point of regulation of body iron stores is at the level of intestinal iron absorption. Repeated blood transfusions for congenital anaemias bypass this regulatory checkpoint and inevitably lead to iron overload in the long-term. Iron overload causes multi-organ dysfunction of the heart, liver, pancreas and joints. It also causes reproductive toxicity primarily through its damaging effect on the anterior pituitary leading to hypogonadotrophic hypogonadism. Another less understood mechanism of reproductive toxicity is direct gonadal damage of excess free iron...

BACKGROUND: Obesity has been described as an independent risk factor for acetabular component malpositioning. The purpose of this study was to determine if this could be overcome by use of fluoroscopic navigation in total hip arthroplasty (THA). METHODS: The first, postoperative, standing, anteroposterior pelvis radiographs from 1599 consecutive patients who underwent fluoroscopic-guided THAs via anterior approach during a six-year period were obtained. We retrospectively reviewed this prospectively collected data...

Joint kinematics can be calculated by Direct Kinematics (DK), which is used in most clinical gait laboratories, or Inverse Kinematics (IK), which is mainly used for musculoskeletal research. In both approaches, joint centre locations are required to compute joint angles. The hip joint centre (HJC) in DK models can be estimated using predictive or functional methods, while in IK models can be obtained by scaling generic models. The aim of the current study was to systematically investigate the impact of HJC location errors on lower limb joint kinematics of a clinical population using DK and IK approaches...

Daniel Lichtenstein
This review article is an update of what should be known for practicing basic lung ultrasound in the critically ill (LUCI) and is also of interest for less critical disciplines (e.g. pulmonology). It pinpoints on the necessity of a professional machine (not necessarily a sophisticated one) and probe. It lists the 10 main signs of LUCI and some of the main protocols made possible using LUCI: the BLUE protocol for a respiratory failure, the FALLS protocol for a circulatory failure, the SESAME protocol for a cardiac arrest and the investigation of a ventilated acute respiratory distress syndrome patient, etc...

The endoscopic, endonasal transcribriform approach (EETA) is an important technique used to directly access the anterior skull base and is increasingly being used in the management of olfactory groove meningiomas (OGMs). As this approach requires removal of the cribriform plate and olfactory epithelium en route to the tumor, patients are anosmic postoperatively. Here, we report the development of phantosmia and dysgeusia in two patients who underwent EETAs for OGMs, which has not yet been reported in the literature...

Background Intracranial wide-neck aneurysms at the arterial bifurcations, especially in the aneurysms where the bifurcating branches emanate directly from the base of the aneurysm, have been particularly difficult on which to perform endovascular treatment. The 'Y'-configuration, double stent-assisted coil embolization is an option for the treatment of these difficult aneurysms, allowing the closure of the aneurysm, preserving the parent arteries. Material and methods In a nine-year period, 546 intracranial aneurysms in 493 patients were treated at our center by endovascular approach...

OBJECTIVE: Involvement of both columns in acetabular fractures is a common presentation; these fractures create a challenging situation for the surgeons in terms of understanding the dimensions of osseous injury and selection of surgical approach. The study was done with an objective to evaluate the efficacy of single posterior approach for acetabular fractures involving both columns directly reducing the posterior wall and column and indirectly reducing the anterior column. METHODS: An evaluation of 25 adult patients 18 male and 7 female presenting in the accident and emergency department of Khyber Teaching Hospital from December 2013 to June 2015 having acetabular fracture involving both the anterior and posterior column were included in this case series study...

BACKGROUND: A new total ankle arthroplasty (TAA) system performed through a lateral approach provides direct visualization of the centre of rotation, allowing for accurate reconstruction of the joint alignment and less bone resection. Radiographic references are needed to describe deformities and plan the surgical procedures. The tibial slope is an important factor when treating malalignment. The aim of this study is to show if there is any difference regarding the post-operative tibial slope (β angle) measurement comparing a fixed-bearing TAA through a lateral approach and a mobile-bearing TAA through an anterior approach...

Daniel Durstewitz
The computational and cognitive properties of neural systems are often thought to be implemented in terms of their (stochastic) network dynamics. Hence, recovering the system dynamics from experimentally observed neuronal time series, like multiple single-unit recordings or neuroimaging data, is an important step toward understanding its computations. Ideally, one would not only seek a (lower-dimensional) state space representation of the dynamics, but would wish to have access to its statistical properties and their generative equations for in-depth analysis...

AIMS: The most effective surgical approach for total hip arthroplasty (THA) remains controversial. The direct anterior approach may be associated with a reduced risk of dislocation, faster recovery, reduced pain and fewer surgical complications. This systematic review aims to evaluate the current evidence for the use of this approach in THA. MATERIALS AND METHODS: Following the Cochrane collaboration, an extensive literature search of PubMed, Medline, Embase and OvidSP was conducted...

Migraine pathophysiology includes altered brainstem excitability, and recent neuromodulatory approaches aimed at controlling migraine episodes have targeted key brainstem relay and modulatory nuclei. In this study, we evaluated the impact of respiratory-gated auricular vagal afferent nerve stimulation (RAVANS), a novel neuromodulatory intervention based on an existing transcutaneous vagus nerve stimulation approach, in the modulation of brainstem activity and connectivity in migraine patients. We applied 3T-functional magnetic resonance imaging with improved in-plane spatial resolution (2...

Minimally invasive atrial septal defect closure and tricuspid annuloplasty in female patients are normally performed through a right submammary anterior minithoracotomy approach. However, when the aortic root is located higher, the direction of aortic cannulation becomes not ideal through the submammary incision. In such cases, transareolar approach is useful. Through this approach, aortic cannulation and tricuspid operation can be performed with endoscopic assistance, and ASD closure can be performed under direct vision...
