Rhabdomyosarcoma is highly aggressive malignant form of mesenchymal tumor arising from skeletal muscle cells rhabdomyoblast, that have failed to fully differenciate. It is most commonly seen in the children before 12 year of age. Primary spinal rhabdomyosarcoma is very rare. A 2 year old girl presented with mass over right upper back and inability to move lower limb. Patient underwent dorsal laminectomy and excision of the mass. Histology and molecular pathology helps in definite diagnosis and further need of chemotherapy or radiotherapy.

Full textAbstract:
Low back pain (LBP) is a common condition in individuals which experienced psychology and physical trauma. LBP is usually found in persons with lower-limb amputation (LLA), as the most common sign of somatisation or inappropriately made prostheses. Our goal was to investigate cases of chronic pain syndrome in persons with LLA and to determine factors, which influence their functional inability due to LBP. Pain after LLA has been studied. 37 persons, including 26 war veterans (70.2 %) and 11 (29.8 %) civilians with LLA due to an illness, were examined. All participants gave their informed consent and filled Oswestry index of disability due to chronic LBP, divided into 10 sections with 6 questions each, with marks in the range 0-5. The average age of 37 analyzed participants with LLA was 46.2+-10.92 years. 30 participants (81.1 %) were married, 4 (10.8 %) were single and 3 (8.1 %) were widows. 27 (73.0 %) participants had below the knee amputation, 5 (13.5 %) had above the knee amputation and 5 (13.5 %) had foot amputation. 33 (89.6 %) participants experienced chronic LBP in the last 2-10 years and 4 (10.8 %) did not have pains. According to Oswestry index for chronic pain higher level of social functionality was found in civilian amputees than in war veterans (p<0.05). Married civilian amputees have higher level of disability during seating (p<0.01), sleeping (p<0.01) and traveling (p<0.05). Higher level of social disorder among civilian amputees is due to the fact that they belong to older group of participants which usually have social integration at the lower degree. More serious problems during seating, traveling and sleeping among this group are probably due to co morbidity. Chronic LBP was found among 89.6 % of the participants. Higher level of social disorder, problems during seating, traveling and sleeping were identified in the civilian amputees and the married participants.

Background: Postoperative urinary retention (POUR) is a common problem with overall rates looking at the entire surgical population quoted between 4% and 6%. POUR has been defined as the inability to void in the presence of a full bladder.Methods: This was a prospective, single-centre, observational study conducted between June 2015 to December 2016 at a tertiary care centre of Northern India. The study group enrolled 186 patients undergoing various lower limb surgeries under spinal anesthesia.Results: In the present study, out of 186 patients, 101 patients were male and 85 patients were female. Most of the patients were in the 41-60 years age group (78) followed by 72 patients were in the >61 years age group. 21 patients (11.29%) suffered with post operative urine retention (POUR) in whom catheterization was required, the incidence of POUR in joint replacement surgeries was 20.96% (13/62). In the present study incidence of POUR was more in males (12 patients) as compared to females (9 patients). POUR was more common in the elderly age group.Conclusions: By carefully identifying patients at risk, adopting appropriate anesthetic techniques and perioperative care principles and accurately monitoring bladder volume by ultrasound, POUR may be prevented and the associated morbidity minimized. Hence it becomes imperative to evaluate the true incidence and consequences of POUR in large prospective clinical studies. Spontaneous micturition should remain a criterion for discharge after spinal anaesthesia.

Full textAbstract:
Leg swing in human walking has historically been viewed as a passive motion with little metabolic cost. Recent estimates of leg swing costs are equivocal, covering a range from 10 to 33 per cent of the net cost of walking. There has also been a debate as to whether the periods of double-limb support during the stance phase dominate the cost of walking. Part of this uncertainty is because of our inability to measure metabolic energy consumption in individual muscles during locomotion. Therefore, the purpose of this study was to investigate the metabolic cost of walking using a modelling approach that allowed instantaneous energy consumption rates in individual muscles to be estimated over the full gait cycle. At a typical walking speed and stride rate, leg swing represented 29 per cent of the total muscular cost. During the stance phase, the double-limb and single-limb support periods accounted for 27 and 44 per cent of the total cost, respectively. Performing step-to-step transitions, which encompasses more than just the double-support periods, represented 37 per cent of the total cost of walking. Increasing stride rate at a constant speed led to greater double-limb support costs, lower swing phase costs and no change in single-limb support costs. Together, these results provide unique insight as to how metabolic energy is expended over the human gait cycle.

Full textAbstract:
Introduction: Lower extremity amputation prevention (LEAP) is an ongoing programme in our institution aimed at limb salvage in patients with critical limb ischaemia (CLI). Patients in the LEAP programme with reconstructible anatomy on initial Doppler imaging received either bypass surgery or percutaneous transluminal balloon angioplasty (PTA). We describe the 1-year limb salvage rates in 46 consecutive patients with CLI who received PTA in 2005. Clinical Picture: A total of 46 patients, 28 women and 18 men, between the ages of 40 and 91 years old (mean age, 70.8) received PTA in 2005. The most common presenting symptom was rest pain (n = 23), followed by pre-existing gangrene (n = 20), non-healing ulcer (n = 17) and cellulitis (n = 8). The majority of the patients (57%) had 3 to 4 risk factors. Diabetes mellitus (91%) and hypertension (80%) were the 2 most common risk factors. The patients were kept under surveillance for periods ranging from 12 to 21 months with a mean of 13.3 months, both clinically and with haemodynamic measurements [ankle-brachial index (ABI), toe pressure (TP) and digital-brachial index (DBI)]. Treatment: The aim of PTA is to achieve straight-line flow from the abdominal aorta down to either a patent dorsalis pedis or plantar arch with limb salvage as the ultimate goal. The patterns of the treated segments were as follows: aorto-iliac occlusions (n = 3), pure infrapopliteal disease (n = 5), femoropopliteal disease with at least 1 good infrapopliteal run-off vessel (n = 16) and combined femoropopliteal and infrapopliteal disease (n = 25). Technical success was achieved in 89% of patients (41 out of 46 patients). The most common cause of technical failure is the inability to cross long chronic total occlusions. Outcome: Paired T test was performed and showed statistically significant improvement in haemodynamic markers within the technically successful group. This included increase in the mean ABI from 0.62 (pre-angioplasty) to 0.91 (Day 1 post-angioplasty), an increase of 0.29 [95% confidence interval (95% CI), 0.1953 to 0.3875; P <0.001]. One year post-angioplasty, the mean ABI was 0.84, an increase of 0.22 (95% CI 0.1512 to 0.3121; P <0.001). There was also significant increase in the mean DBI of 0.17 from 0.23 to 0.41 (pre-angioplasty versus Day 1 post angioplasty – 95% CI of 0.1006 to 0.2433; P <0.001). In addition, significant increase in the mean TP of 28.2 mmHg from 36.8 to 63.2 mmHg (pre-angioplasty versus Day 1 post angioplasty – 95% CI, 18.493 to 37.939; P <0.001) was also noted. Of the 23 patients who presented with rest pain, total abolishment of symptoms was achieved in 21 patients (91%). Healing of pre-existing gangrene was attained in 15 patients (66%). Five patients subsequently received minor amputation for pre-existing gangrene. Clinical improvement in all the patients who presented with non-healing ulcers (n = 17) and cellulitis (n = 8) was attained. More importantly, all healed ulcers remained healed throughout the study period. The limb salvage rates were 93% at 1 month, 87% at 3 months, 82% at 6 months and 78% at 1 year. Conclusion: Angioplasty is a safe and effective limb salvage method in patients with CLI and has a high 1-year limb salvage rate.

Each year, 50% of runners suffer from injuries. Consequently, more studies are being published about running biomechanics; these studies identify factors that can help prevent injuries. Scientific evidence suggests that recreational runners should use personalized biomechanical training plans, not only to improve their performance, but also to prevent injuries caused by the inability of amateur athletes to tolerate increased loads, and/or because of poor form. This study provides an overview of the different normative patterns of lower limb muscle activation and articular ranges of the pelvis during running, at self-selected speeds, in men and women. Methods: 38 healthy runners aged 18 to 49 years were included in this work. We examined eight muscles by applying two wearable superficial electromyography sensors and an inertial sensor for three-dimensional (3D) pelvis kinematics. Results: the largest differences were obtained for gluteus maximus activation in the first double float phase (p = 0.013) and second stance phase (p = 0.003), as well as in the gluteus medius in the second stance phase (p = 0.028). In both cases, the activation distribution was more homogeneous in men and presented significantly lower values than those obtained for women. In addition, there was a significantly higher percentage of total vastus medialis activation in women throughout the running cycle with the median (25th–75th percentile) for women being 12.50% (9.25–14) and 10% (9–12) for men. Women also had a greater range of pelvis rotation during running at self-selected speeds (p = 0.011). Conclusions: understanding the differences between men and women, in terms of muscle activation and pelvic kinematic values, could be especially useful to allow health professionals detect athletes who may be at risk of injury.

Full textAbstract:
The study aimed to evaluate clinical and vascular characteristics, as well as outcomes, for diabetic persons with foot ulceration and no-option critical limb ischemia (CLI). The study group included a sample of patients admitted to our diabetic foot unit because of a new diabetic foot ulcer and CLI. All subjects were managed using a limb salvage protocol which includes lower-limb revascularization. According to whether or not the revascularization procedure was a success, patients were respectively divided into two groups: successfully treated CLI patients (ST-CLI) and no-option CLI patients (NO-CLI). Failed revascularization was considered in the case of technical recanalization failure of occluded vessels (inability to overcome the obstruction) and/or absence of arterial flow to the foot. Limb salvage, major amputation, and death after 1 year of follow-up were evaluated and compared between the two groups. Overall, 239 patients were included, 74.9% belonging to ST-CLI and 25.1% to NO-CLI. NO-CLI patients reported more cases of ischemic heart disease (80 vs. 62.1, p = 0.008), heart failure (63.3 vs. 32.4%, p < 0.0001), and end-stage renal disease (ESRD) (60 vs. 25.7%) than ST-CLI patients. In addition, more vessels were affected in the NO-CLI group (5.2 ± 1.6 vs. 4 ± 1.5, p < 0.0001), and there was more involvement of tibio-peroneal trunk (50 vs. 30.2%, p = 0.006), anterior tibial (93.3 vs. 82.7, p = 0.03), posterior tibial (93.3 vs. 73.7%, p = 0.0005), peroneal (70 vs. 48%, p = 0.002), and below-the-ankle arteries (73.3 vs. 39.1%, p < 0.0001) than ST-CLI. The 1 year outcomes for the whole population were 69.9% limb salvage, 10.9% major amputation, and 19.2% death. The outcomes for NO-CLI and ST-CLI were, respectively, as follows: limb salvage (13.8 vs. 73.4%, p < 0.0001), amputation (30 vs. 4.5%, p = 0.0001), and mortality (50 vs. 8.9%, p < 0.0001). NO-CLI patients showed a more severe pattern of peripheral arterial disease (PAD) with distal arterial lesions and worse outcomes than ST-CLI.

Full textAbstract:
Aim: The aim of this study was to explore structural, functional, and cognitive characteristics of social relationships of women across and within three types of disability, as well as aspects of their social participation in the wider community – barriers and facilitators of their social and physical environment in that respect. The three types of disability explored were: sensory (deafness), physical (inability to move lower limbs), and mental (psychotic disorder).
Methods: In the study participated 30 women – 10 per type of disability – aged 22-44, living in the metropolitan area of Milan (Italy), and having at least one role of relative autonomy. Qualitative semi-structured face-to-face interviews were conducted. All interviews were held in Italian language [or Italian Sign Language (LIS) for six deaf participants], and were audio recorded and transcribed verbatim. Data analysis was conducted using the template analysis technique of thematic analysis. Comparisons within and across the three types of disability were performed as well.
Main findings: The findings highlighted barriers that women with disability face within their social and physical environment. In specific, it emerged that women with mental disability faced prejudice, discrimination, stigmatisation, and/or lack of empathy towards them from other people of the wider population which hinder their social participation. All women with physical disability faced barriers to social participation related to numerous accessibility hindrances of the physical environment, and most of them had also faced prejudice and mentality barriers towards them from persons of the wider population. Women with sensory disability encountered mostly barriers for social participation related to lack of resources for communication with people of the general population, whether in private or public places, when there is no sign language interpreter or subtitles, while they have also limited opportunities for employment compared to hearing persons. From comparison across types of disability various common patterns emerged. Women with mental disability appeared to have the lowest level of social participation, whereas women with physical disability the highest.
Conclusion: It appears compelling to focus on the exploration of aspects of the social relationships and social participation of persons with disability since the barriers they face relevantly are numerous, multi-faceted and related to their personal and social development. The biopsychosocial model of health and disability could be employed towards the goal of full social inclusion.

Visual disability affects about 2 million Poles. This group includes people who have been diagnosed with Stargardt’s disease. This disease occurs in the general population with a frequency of one in 10,000. It leads to legal blindness with visual acuity lower than 5%. Visual disturbances in this disease may occur in children, i.e. 7–12 years of age, as well as in adolescents and adults. People suffering from this disease experience a significant reduction in visual acuity, difficulty in recognizing colors, impaired depth vision, difficulties with accommodation, impaired central vision and often severe photophobia. The aim of the research was to collect information about the assistive technologies used by people with Stargardt’s disease and to identify their ability to move independently despite a significant reduction in visual acuity. The research results show that most of the 102 surveyed people use various types of assistive technology and experience significant visual impairment. At the same time, a significant part of this group declares that despite the inability to read the black print text, they can still move quite freely.

This chapter details how the younger generations and lower-income households are most affected by the housing and homelessness crisis. It shows how huge aspects of their lives have become precarious and insecure, as a result of insecure, low-paid and often part-time jobs, and insecure and unaffordable housing. Generation Rent is the new housing precariat, living with precarious housing, precarious work contracts and an inability to access mortgage credit, alongside unaffordable house prices and rent. It details the structural shift in Ireland’s housing system: decline in home-ownership rates and rise in private rental sector. Generation Rent now extends to the middle-aged and older generations as shown in the increase in the number of people renting in their 40s and 50s. It looks at increasing housing cost overburden rates where young people on low incomes are most severely affected by the issue of housing affordability than young people on higher incomes. Generation Rent also includes Generation Stuck at Home - those forced to live at home with theirparents as they cannot afford to move out into the rental sector, orbecause they have been evicted, unable to meet mortgages, cannot access social housing, or are trying to savefor a deposit.

Full textAbstract:
There is a basic body plan common to most of the animals presented in this book. At its most obvious, they all have a head, a body, and four limbs. Most are four-legged and stand on all fours, and are described as having front limbs and rear limbs. The front limb is anatomically equivalent to the arm and hand in humans and primates, and the rear limb to the human lower limb. The animals in this book are surprisingly similar in many ways. The head is connected to the rib cage by the neck vertebrae and the rib cage is connected to the pelvis by the lumbar vertebrae. The two front limbs are connected to the rib cage, and the two rear limbs are connected to the pelvis. These units move in relation to one another, establishing the stance, or pose, of an animal. Animals differ primarily in the shape and relative proportions of these structural units, in the position of the wrist, heel, and toe bones when standing and walking, and by the number of their toes. An animal can be visualized as being constructed of a series of simplified, three-dimensional, somewhat geometric volumes (head, forearm, thigh). Each of these volumes has one dimension that is longer than the others. A line projected through the center of the mass of this volume on its longest dimension is called its axis (plural, axes). For the most part, especially in the limbs, these axes follow the skeleton, so that a line drawn through the long dimension of a bone is on, or close to, the axis of the volume of that region (for example, the position of the radius is close to the axis of the forearm). One of the more confusing regions of the body is the volume of the upper arm. The humerus (upper arm bone) is mostly deeply buried in muscle, and lies toward the front of this muscle mass, with the massive triceps muscle located at its rear.

Full textAbstract:
A 72-year-old man sought care for predominant choreiform movements, mild gait ataxia, urinary dysfunction, and abnormal nocturnal behaviors. Choreiform movements were nearly constant while awake, vanished during sleep, and predominantly involved his lower extremities and trunk. He also had urinary dysfunction, with urinary hesitancy and frequency. Sleep-related behaviors included sleep talking, sleep singing, sudden single-limb jerking movements, and complex hand movements. He also had daytime sleepiness. On neurologic examination, abnormal findings included postural instability at baseline with eyes open and a slightly wide-based tentative gait and inability to execute tandem walking. He had intermittent choreiform movements of the legs and the left shoulder. He also had occasional repetitive, periodic, voluntary-appearing, triple flexion–type movements of both legs. Overnight polysomnography was ordered to evaluate nocturnal movements. Polysomnography revealed rapid periodic leg movements of sleep and rapid eye movement sleep without atonia. Sleep architecture was mildly deranged, with electroencephalographic alpha intrusion throughout nonrapid eye movement sleep, as well as absent slow-wave sleep. Ferritin level was suboptimal. Evaluation of serum for autoimmune encephalitis demonstrated IgLON family member 5 antibody positivity by tissue immunofluorescence assay, confirmed by cell-based assay. The patient was diagnosed with IgLON family member 5 autoimmune encephalitis and symptomatic rapid eye movement sleep behavior disorder. The patient was instructed to maintain a safe sleep environment at home and to begin taking melatonin at bedtime. A therapeutic trial of intravenous methylprednisolone, together with mycophenolate mofetil, was followed by improvement in memory, confusion, and hallucinations, waking involuntary movements, bladder dysfunction, and sleep quality. Rapid eye movement sleep behavior disorder is a parasomnia characterized by rapid eye movement sleep without atonia, the loss or dysregulation of normal rapid eye movement sleep atonia, which is its pathophysiologic signature, and which is permissive for dream enactment behaviors during rapid eye movement sleep.

Full textAbstract:
Standing from a seated position is a common, yet dynamically challenging task. Due to the vertical ascent of the body center of gravity, sit-to-stand (STS) transition requires high torque output from the knee. As a result, STS transition poses a major barrier to the mobility of individuals with lower-limb issues, including the transfemoral (TF, also known as above-knee) amputees. A study showed that unilateral TF amputees suffer from high asymmetry in ground reaction forces (53∼69%) and knee moments (110∼124%), while the asymmetry for healthy controls is less than 7% [1]. Note that, although a powered TF prosthesis (Power Knee™) was used in this study, it generated resistance in the STS and thus produced similar results as the passive devices. The inability of existing prostheses in generating knee torque and regulating the torque delivery in the STS seriously affects the mobility of TF amputees in their daily life. Motivated by this issue, researchers have developed numerous powered TF prostheses (e.g., Vanderbilt powered TF prostheses [2]). These devices are able to generate torque and power for challenging tasks such as STS transition. Making full use of such capability, however, requires an effective controller. Currently, walking control for powered prostheses has been well established, but STS control is much less investigated. Varol et al. developed a multi-mode TF prosthesis controller, in which STS is treated as a transitional motion between sitting and standing states [2]. However, no details were provided on the rationale of the STS controller structure or the determination of the control parameters. In this paper, a new prosthesis control approach is presented, which regulates the power and torque delivery in the STS process. Inspired by the biomechanical behavior of the knee in the STS motion, the new controller provides two desired functions (gradual loading of the knee at the beginning, and automatic adjustment of the knee torque according to motion progress) with a single equation. Combined with a simple yet reliable triggering condition, the proposed control approach is able to provide natural STS motion for the powered knee prosthesis users.

Full textAbstract:
A physics-based computational model of neonatal Developmental Dysplasia of the Hip (DDH) following treatment with the Pavlik Harness was developed to obtain muscle force contribution in order to elucidate biomechanical factors influencing the reduction of dislocated hips. Clinical observation indicates that reduction occurs in deep sleep and involves passive muscle action. Consequently, a set of five (5) adductor muscles, namely, the Adductor Brevis, Adductor Longus, Adductor Magnus, Pectineus, and Gracilis were identified as mediators of reduction using the Pavlik Harness. A Fung-type model was used to characterize the hyperelastic stress-strain muscle response. Four grades (1–4) of dislocation as specified by the International Hip Dysplasia Institute (IHDI) were considered. A three-dimensional model of the pelvis-femur-lower limb assembly of a representative 10 week-old female was generated based on CT scans of a 6-month and 14-year old female as well as the visible human project with the aid of anthropomorphic scaling of anatomical landmarks. The muscle model was calibrated to achieve equilibrium at 90° flexion and 80° abduction. The hip was computationally dislocated according to the grade under investigation, the femur was restrained to move in an envelope consistent with Pavlik Harness restraints, and the dynamic response under passive muscle action and under the effect of gravity was resolved using the ADAMS solver in Solidworks. Results of the current model with an anteversion angle of 50° show successful reduction IHDI Grades 1–3, while IHDI Grade 4 failed to reduce with the Pavlik Harness. These results are consistent with a previous study based on a simplified anatomically-consistent synthetic model and clinical reports of very low success of the Pavlik Harness for Grade 4. However, our model indicates that it is possible to achieve reduction of Grade 4 dislocation by hyperflexion. This finding is consistent with clinical procedures that utilize hyperflexion to help achieve reduction for patients with severe levels of DDH for whom the Pavlik Harness fails.
