Fang Cui, Xiangru Zhu, Yuejia Luo
Two hypotheses have been proposed regarding the response that is triggered by observing others' pain: the "empathizing hypothesis" and the "threat value of pain hypothesis." The former suggests that observing others' pain triggers an empathic response. The latter suggests that it activates the threat-detection system. In the present study, participants were instructed to observe pictures that showed an anonymous hand or foot in a painful or non-painful situation in a threatening or friendly social context. Event-related potentials were recorded when the participants passively observed these pictures in different contexts...

PURPOSE: In this study, the distance between the insertion point of the suture anchors and posterior surface of the fibula during arthroscopic lateral ankle ligament repair was investigated on computed tomography (CT) images. The hypothesis of this study was that there is an optimal insertional direction of the suture anchor to avoid anchor-related complications. METHODS: One hundred eleven ankles of 98 patients who had undergone three-dimensional CT scans for foot or ankle disorders without deformity of the fibula were assessed (59 males, 52 females; median age 25...

Wolfram Müller, Alexander Jung, Helmut Ahammer
Physiological processes are regulated by nonlinear dynamical systems. Various nonlinear measures have frequently been used for characterizing the complexity of fractal time signals to detect system features that cannot be derived from linear analyses. We analysed human balance dynamics ranging from simple standing to balancing on one foot with closed eyes to study the inherent methodological problems when applying fractal dimension analysis to real-world signals. Higuchi dimension was used as an example. Choice of measurement and analysis parameters has a distinct influence on the computed dimension...

A skeleton with a number of abnormalities is described involving full discussion of alternative diagnoses. In this complex case, the primary diagnosis is of avulsion of the stem of the bifurcate ligament causing a fracture of the anterior process of the calcaneus. The bilateral fracture identified in Skeleton 3A-7 from Site 12, a Capsian site in Algeria, is a result of the feet being inverted and plantar flexed: the fracture is prone to non-union, which is asymmetrical here. There is also a separate anatomical variation of the feet, 3rd cuneiform and 3rd metatarsal coalition, which was not the cause of trauma...

BACKGROUND: Persistent pain despite a total ankle replacement is not uncommon. A main source of pain may be an insufficiently balanced ankle. An alternative to the revision of the existing arthroplasty is the use of a corrective osteotomy of the distal tibia, above the stable implant. This strictly extraarticular procedure preserves the integrity of the replaced joint. The aim of this study was to review a series of patients in whom a corrective supramalleolar osteotomy was performed to realign a varus misaligned tibial component in total ankle replacement...

BACKGROUND: Ankle fractures account for 9% of all fractures seen in the United Kingdom. 15,000 of these fractures undergo operative fixation each year. Soft tissue swelling impacts on timing of fixation due to fears of infection and wound dehiscence. The use of arterio-venous foot pumps (AVFP) is increasing in this population although the evidence for their efficacy is unclear. In order to address this, we present an overview of the evidence for AVFP device use following ankle fracture...

REVIEW
Andrew M Horwood, Nachiappan Chockalingam
Abnormal-pronation, excessive-pronation, over-pronation, or hyper-pronation, are terms with a long historical use in both medical and research terminology pertaining to an abnormal movement of the foot. These terms are commonly used as a potential kinematic aetiology to explain the occurrence of multiple lower limb and foot pathologies. Yet despite this widespread use there is no clear definition to explain what the terms abnormal, excess, over, or hyper-pronation, mean. Without a strict definition the use of these terms as a patho-mechanical explanation of injuries, leaves a distinct lack of clarity and is meaningless in regards to being able to distinguish what movement may need clinical intervention...

BACKGROUND: Long bone posttraumatic osteomyelitis (PTOM) is a relatively common complication following surgical fixation of open fractures. There is a lacking consensus on ideal strategies for diagnostic evaluation of long bone PTOM. While open bone biopsy and culture is considered the 'gold diagnostic standard,' its cost and invasiveness are often prohibitive and have prompted the search for alternate diagnostic methods. OBJECTIVE: To evaluate the sensitivity and specificity of various diagnostic modalities relative to open bone biopsy and culture for the detection of long bone PTOM...

Motor-activity-related mental tasks are widely adopted for brain-computer interfaces (BCIs) as they are a natural extension of movement intention, requiring no training to evoke brain activity. The ideal BCI aims to eliminate neuromuscular movement, making motor imagery tasks, or imagined actions with no muscle movement, good candidates. This study explores cortical activation differences between motor imagery and motor execution for both upper and lower limbs using functional near-infrared spectroscopy (fNIRS)...

Angiomyofibroblastoma is a rare benign soft tissue tumor that arises predominantly in the female genital tract. It occurs less commonly in the scrotum, spermatic cord, and the retroperitoneum. Its diagnosis is based on specific histological and immunopathological features. However, the condition has never been previously described in the extremities. We present the first case report of angiomyofibroblastoma presenting as a slow-growing tumor in the foot of a 48-year-old lady.

AIMS: Diabetes-related microvascular disease has been implicated in the development of foot ulceration and amputation. Assessment of microvascular function may be effective in identifying those at risk of diabetic foot complications. We investigated the relationship between active or previous foot complication and post-occlusive reactive hyperaemia (PORH) measured by laser-Doppler fluxmetry (LDF) in people with type 2 diabetes. METHODS: PORH measures were obtained from the hallux apex in 105 people with type 2 diabetes...

OBJECTIVE: There is a paucity of research on patients presenting with uninfected diabetic foot ulcers (DFU) that go on to develop infection. We aimed to investigate the incidence and risk factors for developing infection in a large regional cohort of patients presenting with uninfected DFUs. METHODS: We performed a secondary analysis of data collected from a validated prospective state-wide clinical diabetic foot database in Queensland (Australia). Patients presenting for their first visit with an uninfected DFU to a Diabetic Foot Service in one of thirteen Queensland regions between January 2012 and December 2013 were included...

Enterovirus71 (EV71) is the major causative agent of hand, foot and mouth disease, which threatens the health of infants and young children. The expression of inflammatory cytokines induced by this viral infection aggravate the illness. Here, we describe the anti-EV71 activity of a specific p38 inhibitor that regulates the p38-MAPK signaling pathway. PD169316 was specifically selected from a MAPK compound library due to its significant inhibitory effect on EV71 replication. PD169316 also reduced EV71-induced apoptosis...

Athletic children are prone to overuse injuries, especially at the heel and knee. Since footwear is an extrinsic factor of lower limb injury risk, the aim of this study was to assess the influence of shoe aging on children running biomechanics. Fourteen children active in sports participated in a laboratory biomechanical evaluation. A new pair of shoes was provided to each participant at an inclusion visit. Four months later, the participants performed a running task and their kinematics and kinetics were assessed both with their used shoes and with a new pair of shoes identical to the first...
