Visceral artery revascularisation through a retroperitoneal approach provides an infrequent yet viable, alternative means of managing mesenteric ischaemia in patients with previous abdominal operations. We present a unique case implementing this surgical approach in a 55-year-old man in which we performed a retroperitoneal aortobifemoral bypass with concomitant retrograde jump graft from the aortic prosthesis to the superior mesenteric artery (SMA) for bilateral lower extremity rest pain and chronic mesenteric ischaemia...

The antiphospholipid syndrome (APS), either primary or secondary form, is considered an autoimmune disease with the presence of at least 1 clinical and 1 laboratory abnormalities as defined by the Sydney criteria. Clinical criteria include vascular thrombosis of venous, artery, small vessel in any organ, and recurrent pregnancy pathologies. Mesenteric ischemia is a rare and threatening manifestation of APS. We herein report a case of a 34-year-old pregnant woman referred to our Emergency Room with thoracic and abdominal acute pain...

INTRODUCTION: Orthostatic myoclonus (OM) is a recognized syndrome of gait unsteadiness accompanied by lower limb myoclonus provoked by the assumption of an upright posture. OM typically affects the elderly and is often associated with neurodegenerative disease. We sought to review the clinical and electrophysiologic characteristics of OM due to brain tumor treatment, the first reported lesional cases of this rare disorder. METHODS: The database of the Mayo Clinic Rochester Movement Disorders Laboratory was searched for all patients diagnosed with OM from January 2007 to December 2016...

P Cintas
Within lower motor neuron diseases, benign focal amyotrophy is a rare syndrome characterized by insidious neurogenic asymmetric atrophy restricted to upper or lower limbs with a good prognosis over time. Described under several terms, the nosology is probably heterogeneous. In juvenile distal upper-limbs forms, specific MRI signs with in particular a compression of the spinal cord by forward displacement of dura, lead to evoke a mechanical process. In other forms, occurring later in the life, affecting proximal part of upper limbs or lower limbs, the physiopathology is still unknown and a focal spinal muscular atrophy is suspected...

Spinal and bulbar muscular atrophy (SBMA) is a rare X-linked motor neuron disease with significant phenotypic viability. Here, we present a genetically identified SBMA family without bulbar paralysis or androgen insensitivity. All four male patients presented with progressive lower motor neuron paralysis in all limbs, with distal extremities more dominant. None of them had bulbar palsy or androgen insensitivity. A consistently mild elevated blood creatine phosphokinase (CPK) levels were detected in all patients and the EMG showed a chronic neurogenic damage...

Autosomal dominantly inherited mutations of BICD2 are associated with congenital-onset spinal muscular atrophy characterised by lower limb predominance. A few cases have also showed upper motor neuron pathology, including presenting with features resembling hereditary spastic paraplegia. The age-of-onset for the published families is usually at birth but also included cases with childhood- and adult-onset disease. In this report we described two isolated probands that presented in utero with features associated with reduced fetal movements...

Motor units are the fundamental elements responsible for muscle movement. They are formed by lower motor neurons and their muscle targets, synapsed via neuromuscular junctions (NMJs). The loss of NMJs in neurodegenerative disorders (such as amyotrophic lateral sclerosis or spinal muscle atrophy) or as a result of traumatic injuries affects millions of lives each year. Developing in vitro assays that closely recapitulate the physiology of neuromuscular tissues is crucial to understand the formation and maturation of NMJs, as well as to help unravel the mechanisms leading to their degeneration and repair...

Spinal muscular atrophy (SMA) is an autosomal recessive neurodegenerative disease characterized by motor neurons degeneration and muscular atrophy. There is no effective SMA treatment. Loganin is a botanical candidate with anti-inflammatory, anti-oxidant, glucose-lowering and anti-diabetic nephropathy activities. The aim of this study is to investigate the potential protective effects of loganin on SMA using two cellular models, SMN-deficient NSC34 cells and SMA patient fibroblasts, and an animal disease model, SMAΔ7 mice...

Hirayama disease, also known as Sobue disease is a rare nonprogressive spinal muscular atrophy. Here, we report a case series of three young males presenting with atrophy of distal upper limb and Hirayama disease as their clinico-radiological diagnosis. Magnetic resonance imaging (MRI) revealed loss of cervical lordosis with focal areas of lower cervical cord atrophy in a neutral position. MRI in flexion position revealed, anterior displacement of the detached posterior dura from the underlying lamina compressing the thecal sac and widened posterior epidural space with flow voids seen better on 3D-CISS images...

The coral reef aorta (CRA) is a rare syndrome commonly referred to a distribution of calcified plaques in the visceral part of the aorta. Because those plaques can cause malperfusion of the lower limbs, visceral ischemia or renovascular hypertension, surgical treatment is recommended. Transaortic endarterectomy is accepted as a standard repair and it is often performed through an extensive thoracoabdominal approach. CRA has been reported in association with polidistrectual atherosclerotic disease, such as Leriche syndrome...

Charcot-Marie-Tooth disease is a group of genetically heterogeneous disorders characterized by a sensorimotor polyneuropathy with subsequent muscle atrophy, areflexia, and sensory loss. More than 60 genes have been linked to Charcot-Marie-Tooth phenotypes, including IGHMBP2. Until recently, mutations in IGHMBP2 were exclusively associated with spinal muscular atrophy with respiratory distress (SMARD1). We present a sibling pair with a novel homozygous truncating mutation in IGHMBP2. The patients presented with childhood-onset distal weakness, wasting in the upper and lower limbs, areflexia and decreased sensation, but no respiratory involvement...

Shape memory alloys (SMAs) are a very promising class of metallic materials that display interesting nonlinear properties, such as pseudoelasticity (PE), shape memory effect (SME) and damping capacity, due to high mechanical hysteresis and internal friction. Our group has applied SMA in the field of neuromuscular rehabilitation, designing some new devices based on the mentioned SMA properties: in particular, a new type of orthosis for spastic limb repositioning, which allows residual voluntary movement of the impaired limb and has no predetermined final target position, but follows and supports muscular elongation in a dynamic and compliant way...

BACKGROUND: Mutations of the lamin A/C gene have been associated with several diseases such as Emery-Dreifuss muscular dystrophy, dilated cardiomyopathy and Charcot-Marie-Tooth disease, referred to as laminopathies. Only one report of spinal muscular atrophy and cardiomyopathy phenotype with lamin A/C gene mutations has been published. The concept that lamin A/C gene mutations cause spinal muscular atrophy has not been established. CASE PRESENTATION: We report a man aged 65 years who presented with amyotrophy of lower limbs, arrhythmia and cardiac hypofunction...

Popliteal artery aneurysms (PAAs) occur in approximately 1 of every 100 men ages 65 to 80 years. They can occur bilaterally, and abdominal aortic aneurysm is simultaneously present in 50% of cases. Therefore, patients with PAAs should undergo ultrasonography to exclude abdominal aortic aneurysms and contralateral PAAs. The main risk of PAAs is thrombus/embolus formation causing lower limb ischemia. Any symptomatic PAA or PAA containing a thrombus should be repaired regardless of size. Asymptomatic PAAs should be considered for repair if the diameter is 2 cm or greater...

BACKGROUND: Major lower limb vascular surgeries may result in severe, remote injury of the gastrointestinal system, which has high mortality rates. Postconditioning is a technique with potential capability of reducing remote gastrointestinal complications. Our aim was to assess the remote macro- and micro-hemodynamic changes of the small intestine following an infrarenal aortic occlusion and to evaluate the effects of postconditioning on these alterations. METHODS: Rats underwent 3h of infrarenal aortic occlusion followed by 4h of reperfusion...
