A twenty-year-old female saddle horse was referred for evaluation of a seven month, non-healing erosive lesion of the right hind hoof with proliferation and bleeding of the underlying soft tissues. This lesion had been twice surgically treated as a canker but rapidly recurred. Histological examination of the second excision revealed a well-differentiated squamous cell carcinoma. At presentation, the horse was mildly depressed, lame and partially non-weight-bearing on the right hind leg, which exhibited a 10 x 10 cm erosive and proliferative lesion remodeling the hoof...

Improving the efficacy of neovascularization is a promising strategy to restore perfusion of ischemic tissues in patients with peripheral arterial disease. The 14q32 microRNA cluster is highly involved in neovascularization. The Mef2a transcription factor has been shown to induce transcription of the microRNAs within this cluster. We inhibited expression of Mef2a using gene-silencing oligonucleotides (GSOs) in an in vivo hind limb ischemia model. Treatment with GSO-Mef2a clearly improved blood flow recovery within 3 days (44% recovery versus 25% recovery in control) and persisted until 14 days after ischemia induction (80% recovery versus 60% recovery in control)...

BACKGROUND: The authors present a technical variation of the standard cannulation for cardiopulmonary bypass perfusion during hyperthermic isolated limb perfusion (ILP) procedures in selected patients with unresectable soft tissue sarcoma or malignant melanoma. PATIENTS: Of 55 ILP procedures performed at our institution since the procedure was established in 2009, nine were performed at the upper extremity. Standard single venous cannulation was used in five cases, and extended, double venous cannulation in the last four...

We investigated the significance of the primary cilia on the macula densa and thick ascending limb (TAL) in regulation of renal hemodynamics, sodium excretion, and blood pressure in this study. A tissue-specific primary cilia knock-out (KO) mouse line was generated by crossing NKCC2-Cre mice with IFT88-Δ/flox mice (NKCC2(CRE); IFT88Δ(/flox)), in which the primary cilia were deleted from the macula densa and TAL. NO generation was measured with a fluorescent dye (4,5-diaminofluorescein diacetate) in isolated perfused juxtaglomerular apparatus...

BACKGROUND: Hyperthermic isolated limb perfusion (HILP) represents an alternative to amputation for patients with either in-transit melanoma or unresectable soft tissue sarcoma, entailing delivery of high-dose chemotherapy after isolation of the extremity, under hyperthermic conditions. Stabilization of the Esmarch elastic bandage is so far performed with the use of Steinmann pins. In this study, we presented our experience with HILP and demonstrated an alternative technique for limb isolation using an Omni-tract retractor instead of the traditional Steinmann pin, while comparing the two methods...

Remote ischemic preconditioning (RIPC) is a phenomenon whereby transient non-lethal ischemia and reperfusion episodes confer protection against prolonged ischemia-reperfusion-induced injury. However, the underlying intracellular signaling has not been extensively explored. The present study aims to inspect the putative involvement of TRPV1 -dependent CGRP release in mediating remote hind limb preconditioning-induced cardioprotection. In the present study, remote hind limb preconditioning stimulus was delivered (4 consecutive episodes of 5 minutes of ischemia-reperfusion) using a blood pressure cuff tied at the inguinal level of the rat...

BACKGROUND: The occlusion of superficial femoris artery (SFA) is a common feature in peripheral vascular disease, so the profunda femoris artery (PFA) is a crucial collateral pathway for the perfusion of the lower limb. The purpose of this study is to discuss the safety, clinical, and hemodynamic efficacy of profundoplasty on the basis of limb salvage, patency, and freedom from reintervention rates. Furthermore, this study aims to identify the risk factors linked to the failure of the procedure...

BACKGROUND: Hyperthermic isolated limb perfusion (HILP) represents a limb-sparing treatment for unresectable soft tissue sarcoma (STS) of the extremities with substantial complete response rates. HILP often provides good functional limb preservation, hence a significant improvement also in terms of quality of life of the patient. Notwithstanding these clear advantages, the traditional technique is still hindered by relatively high post-operative morbidity. METHOD: We treated a 78-year-old female with unresectable angiosarcoma of the left leg using a new surgical approach: an entirely laparoscopic HILP...

INTRODUCTION: Isolated limb perfusion (ILP) is a treatment option for patients with in-transit metastases of malignant melanoma in the extremities, as well as locally advanced sarcoma. ILP allows for a delivery of high-dose chemotherapy to an isolated extremity with minimal systemic toxicity. However, local toxicity like oedema, blistering, nerve damage and compartment syndrome can occur. Myoglobin measurements have been used as a screening method to predict the most severe cases of local toxicity...

Complete response can be difficult to assess after isolated limb perfusion (ILP) for metastatic in-transit melanoma, especially when numerous and unresectable post-necrotic persisting pigmented lesions occur. These residual lesions are mainly seen in the more superficial and pigmented types of metastatic disease and correspond to the residual melanophage granuloma that persists after tumor tissues undergo complete necrosis. Reflectance confocal microscopy (RCM) is a non-invasive technique that allows the exploration of the superficial dermis...

Since the early 20th century extracorporeal perfusion of large animal organs has been used to investigate a broad variety of research questions, thereby overcoming common draw backs of in vitro studies without suffering from ethical concerns associated with live animal research. The technique is in accordance with the 3R principles and represents an excellent opportunity to investigate in detail the physiology of organs under standardised conditions. It is also suitable for the translation of basic pre-clinical research into a more relevant arena prior to or avoiding altogether live animal research...

Aims: We have previously shown that low-dose ionizing radiation (LDIR) induces angiogenesis but there is no evidence that it induces neovascularization in the setting of peripheral arterial disease. Here, we investigated the use of LDIR as an innovative and non-invasive strategy to stimulate therapeutic neovascularization using a model of experimentally induced hindlimb ischemia (HLI). Methods and results: After surgical induction of unilateral HLI, both hindlimbs of female C57BL/6 mice were sham-irradiated or irradiated with four daily fractions of 0...

BACKGROUND: Isolated limb perfusion with TNF-alpha and melphalan (TM-ILP) in combination with complete tumor resection is an effective treatment option for non-resectable soft-tissue sarcoma of the extremities, with limb salvage rates greater than 80%. The aim of this study was to assess quality of life (QoL) after TM-ILP, also with regard to long-term survival. METHODS: We retrospectively examined 27 patients who had primarily non-resectable soft-tissue sarcoma of the leg and who had undergone TM-ILP and complete tumor resection (with limb-sparing intent) during their follow-up examinations using the Quality of Life Questionnaire (QLQ-C30) and the German Short Musculoskeletal Function Assessment (SMFA-D)...

Recent clinical studies have suggested that endothelial progenitor cells (EPCs) transplantation provides a modest benefit for treatment of the ischaemic diseases such as limb ischaemia. However, cell-based therapies have been limited by poor survival of the engrafted cells. This investigation was designed to establish optimal hypoxia preconditioning and evaluate effects of hypoxic preconditioning-induced autophagy on survival of the engrafted EPCs. Autophagy of CD34(+) VEGFR-2(+) EPCs isolated from rat bone marrow increased after treatment with 1% O2 ...

PURPOSE OF REVIEW: The recent discovery of effective systemic treatments for melanoma has dramatically improved the prognosis for patients with advanced disease. As a result, the multidisciplinary management of melanoma has evolved significantly. In the past decades surgery was reserved for symptomatic palliation in patients with metastatic melanoma. Today surgical treatment of patients responding to systemic therapies has become an integral part of disease control. RECENT FINDINGS: Current efforts are focused on minimizing the morbidity of surgery (laparoscopic inguinal lymph node dissection, selective completion lymphadenectomy) as well as combining surgery with systemic therapy in novel ways (neoadjuvant targeted and/or immunotherapy, isolated limb infusion/perfusion with systemic immunotherapy)...

Jihad A Mustapha, Larry J Diaz-Sandoval, Fadi Saab
Critical limb ischemia (CLI) represents the terminal stage of peripheral arterial disease (PAD) and is characterized by multilevel and multivessel disease. Amongst patients with infrainguinal disease, approximately one third have predominantly isolated infrapopliteal disease and the remaining two thirds, a combination of femoropopliteal and infrapopliteal disease. Isolated infrapopliteal disease is mainly seen in the elderly, diabetic, or dialysis-dependent patients. These patients have higher risk of amputation and shorter amputation-free survival...

BACKGROUND: Atherosclerotic peripheral artery disease affects 8% to 12% of Americans >65 years of age and is associated with a major decline in functional status, increased myocardial infarction and stroke rates, and increased risk of ischemic amputation. Current treatment strategies for claudication have limitations. PACE (Patients With Intermittent Claudication Injected With ALDH Bright Cells) is a National Heart, Lung, and Blood Institute-sponsored, randomized, double-blind, placebo-controlled, phase 2 exploratory clinical trial designed to assess the safety and efficacy of autologous bone marrow-derived aldehyde dehydrogenase bright (ALDHbr) cells in patients with peripheral artery disease and to explore associated claudication physiological mechanisms...

Cardioprotective efficacy of remote ischemic preconditioning (RIPC) remains controversial. Experimental studies investigating RIPC have largely monitored cardiovascular changes during index ischemia and reperfusion with little work investigating changes during RIPC application. This work aims to identify cardiovascular changes associated with autonomic nervous system (ANS) activity during RIPC and prior to index ischemia. RIPC was induced in anesthetized male C57/Bl6 mice by four cycles of 5 min of hindlimb ischemia using inflated cuff (200 mmHg) followed by 5 min reperfusion...
