To reduce the invasive nature of extended pelvic lymph node dissections (ePLND) in prostate cancer, we have developed a multicolor fluorescence guidance approach that enables the discrimination between prostate draining lymph nodes (LNs) and lower limb draining LNs. Methods: In five porcine models multispectral-fluorescence guidance was performed using da Vinci Si- and Xi-robot consoles. They received fluorescein into the lower limb(s) and indocyanine green (ICG)-nanocolloid into the prostate. Results: Fluorescein was detected in 29 LNs (average of 3...

BACKGROUND: Atypical lipomatous tumours (ALT) are common adipocytic tumours. Due to their large size and deep-seated location, wide resection might result in severe functional deficits. The question which margins should be aimed is hence discussed controversially. METHODS: Forty consecutive patients underwent limb-sparing resections. Margins were defined as R0 (wide resection), R1 (marginal resection) or R2 if tumour was left. All patients were followed for evidence of local recurrence or remote metastases...

BACKGROUND: Symmetrical peripheral gangrene is characterized as acral (distal extremity) ischemic limb injury affecting two or more extremities, without large vessel obstruction, typically in a symmetrical fashion. Risk factors include hypotension, disseminated intravascular coagulation, and acute ischemic hepatitis ("shock liver"). In contrast, venous limb gangrene is characterized by acral ischemic injury occurring in a limb with deep vein thrombosis. Both symmetrical peripheral gangrene and venous limb gangrene present as acral limb ischemic necrosis despite presence of arterial pulses...

AIMS AND OBJECTIVES: To illuminate the hospital experience for patients and families when major amputation has been advised for critical limb ischaemia (CLI). BACKGROUND: CLI creates significant burden to the health system and the family, particularly as the person with CLI approaches amputation. Major amputation is often offered as a late intervention for CLI in response to the marked deterioration of an ischaemic limb, and functional decline from reduced mobility, intractable pain, infection and/or toxaemia...

The persistent sciatic artery (PSA) is a remnant of the fetal circulatory system that is preserved in less than 0.1% of the population. Up to 60% of patients with this vascular anomaly will go on to development of a PSA aneurysm (PSAA), which can produce a variety of symptoms including neuropathy, claudication, and acute limb-threatening ischemia. Historical management is by open operation and interposition grafting, which can be highly morbid. We describe successful management of a large, symptomatic PSAA by endovascular stent-grafting with intermediate term follow-up...

Recent years have seen a surge of interest in the incorporation of artificial limbs. This research promises to provide individuals with sensorimotor disorders such as amputations with prostheses which feel like their own body part. While neuroscience made a leap towards uncovering the basic neurocognitive mechanisms of bodily self-consciousness, the development of incorporated prosthetic limbs still faces substantial challenges in basic neuroscience and in clinical reality. Here we critically examine recent findings on prosthesis incorporation to aid patient rehabilitation in the context of advances in cognitive and applied neuroscience as well as technology...

Three cases of delated cardiomyopathy (DCM) with conduction defects (OMIM 115200), limb girdle muscular dystrophy 1B (OMIM 159001) and autosomal dominant Emery-Dreifuss muscular dystrophy 2 (OMIM 181350), all associated with different LMNA mutations are presented. Three heterozygous missense mutations were identified in unrelated patients - p.W520R (c.1558T > C), p.T528R (с.1583С > G) and p.R190P (c.569G > C). We consider these variants as pathogenic, leading to isolated DCM with conduction defects or syndromic DCM forms with limb-girdle muscular dystrophy and Emery-Dreifuss muscular dystrophy...

The four R-spondin secreted ligands (RSPO1-RSPO4) act via their cognate LGR4, LGR5 and LGR6 receptors to amplify WNT signalling1-3 . Here we report an allelic series of recessive RSPO2 mutations in humans that cause tetra-amelia syndrome, which is characterized by lung aplasia and a total absence of the four limbs. Functional studies revealed impaired binding to the LGR4/5/6 receptors and the RNF43 and ZNRF3 transmembrane ligases, and reduced WNT potentiation, which correlated with allele severity. Unexpectedly, however, the triple and ubiquitous knockout of Lgr4, Lgr5 and Lgr6 in mice did not recapitulate the known Rspo2 or Rspo3 loss-of-function phenotypes...

We describe a precise and reproducible gene-induction method in the amphibian, Xenopus laevis Tetrapod amphibians are excellent models for studying the mechanisms of three-dimensional organ regeneration because they have an exceptionally high regenerative ability. However, spatial and temporal manipulation of gene expression has been difficult in amphibians, hindering studies on the molecular mechanisms of organ regeneration. Recently, however, development of a Xenopus transgenic system with a heat-shock-inducible gene has enabled the manipulation of specific genes...

The contralateral limb is often used as a control in various clinical, forensic and anthropological studies. However, no studies have been performed to determine if the contra-lateral limb is a suitable control during the bone development period. The aim of this study was to determine the bilateral symmetry of growing rat tibiae in terms of geometric shape, mechanical strength and bone morphological parameters with developmental stages. Left and right tibias of 18 male Sprague-Dawley rats at 4, 8 and 12 weeks of age were scanned with micro-CT for bone-morphometric evaluation and for 3D deviation analysis to quantify the geometric shape variations between left and right tibiae...

Morgan Sangeux
BACKGROUND: Hip rotation kinematics during gait is a key parameter to support clinical decision making, for example in children with lower limb torsional deformities. However, hip rotation kinematics is also one of the least repeatable parameter because it is difficult to locate the position of the medio-lateral axis of the femur. Functional knee calibration provides an alternative to locate the medio-lateral axis of the femur and may be performed retrospectively, using the movement of the knee joint during gait...

Merosin deficient congenital muscular dystrophy 1A (MDC1A) is a very rare autosomal recessive disorder caused by mutations in the LAMA2 gene leading to severe and progressive muscle weakness and atrophy. Although over 350 causative mutations have been identified for MDC1A, no treatment is yet available. There are many therapeutic approaches in development, but the lack of natural history data of the mouse model and standardized outcome measures makes it difficult to transit these pre-clinical findings to clinical trials...
