Vascular ulcer

Faruk Tas, Kayhan Erturk
BACKGROUND: Invasion of the lymphatic or vascular vessels by the primary tumor is considered a sign of aggressive disease that leads to metastases to the regional lymph nodes and to distant sites. Although lymphovascular invasion (LVI) is one of the major characteristics of a primary melanoma tumor, its prognostic significance remains controversial. OBJECTIVE: The objective of this study was to determine the clinical significance of LVI in melanoma patients. METHODS: Outcomes in 705 patients with cutaneous melanoma were investigated retrospectively...

BACKGROUND: We sought to update our prior report of findings on sentinel lymph node biopsy (SLNB) and predictors of a positive SLN in patients with conjunctival or eyelid melanoma. METHODS: We reviewed the records of all patients with ocular adnexal melanoma who underwent SLNB at one institution during 2000-2015. We determined rates of positive and false-negative findings on SLNB, primary tumour features correlated with positive findings and rate of nodal recurrence (false-negative event) after negative findings...

A trophic ulcer is a pressure ulcer caused by external trauma to a part of the body that is compromised due to disease, vascular insufficiency, or loss of afferent nerve fibers. Spinal dysraphism (ie, neural tube defects [NTD]) such as meningomyelocele is a risk factor for developing these ulcers in adults and pediatric patients. Information regarding the occurrence of trophic ulcers in pediatric patients with NTD is lacking. A review of the English-language literature on skin/neuropathic ulcers in patients with NTDs, irrespective of study design, published between 1975 and 2014, was undertaken using the PubMed database...

Acroangiodermatitis (AAD), also known as pseudo-Kaposi's sarcoma, is an uncommon benign angioproliferative condition most commonly seen in the lower extremities. This condition often presents as discolored patches that progress to painful ulcerations. The list of vascular conditions associated with this diagnosis is vast. Acroangiodermatitis presents similarly to more aggressive conditions such as Kaposi's sarcoma, making histopathologic examination helpful in its diagnosis. We present two cases of AAD in the setting of chronic venous insufficiency...

OBJECTIVES: Systemic sclerosis (SSc)-related digital ulcers (DU) cause significant pain and disability and are often a primary endpoint in clinical trials. However, their pathophysiology has been little studied. The objectives of this prospective study were to determine whether laser Doppler imaging (LDI) and thermography can identify ischaemic components in both fingertip and extensor surface DU and assess ulcer healing. METHODS: Patients prospectively reported new DU over a year...

A 72-year-old woman with ulcerative colitis was referred to our hospital because of refractory diarrhea. Although she had been treated with prednisolone 12.5 mg/day and mesalazine suppositories 1 g/day, her watery diarrhea persisted. Colonoscopy was undergone 30 days after she started administration of mesalazine suppositories, and showed granularity of the mucosa with little erythematous appearance in the entire colon with endoscopic Mayo score 1. Double-contrast small-bowel radiography showed a rough mucosal surface in the terminal ileum...

Chronic skin ulcers are frequently encountered in clinical practice and are often due to very heterogeneous etiologies. Cryofibrinogenemia is an unusual cause of non-healing skin ulcers. It is a small-vessel occlusive vascular disorder that results from the precipitation of cryofibrinogens in plasma. The lack of definitive diagnostic criteria means cryofibrinogenemia remains an under-diagnosed entity that causes significant morbidity. One of the most common manifestations of cryofibrinogenemia is skin ulceration...

OBJECTIVE: Cluster of differentiation 163 (CD163) is a receptor that binds haptoglobin-hemoglobin complexes and is mainly expressed on macrophages and monocytes. As a result of shedding, the extracellular portion of CD163 circulates in the blood as a soluble CD163 (sCD163). This study aimed to measure serum sCD163 levels in patients with systemic sclerosis (SSc) and to assess its association with the clinical, laboratory, and radiological features of the disease. MATERIAL AND METHODS: We measured serum sCD163 levels in 24 patients with SSc and in 30 healthy controls...

A 19-year-old male with diarrhea, abdominal pain, fever, and elevated C-reactive protein (CRP) levels was admitted to our hospital. Endoscopic examination and small intestinal contrast radiography revealed multiple longitudinal ulcers in the large intestine and ileum. A specimen biopsied from one of these ulcers revealed non-caseating epithelioid cell granuloma. He also had a draining anal fistula. Plain chest computed tomography (CT) and abdominal contrast-enhanced CT did not reveal any vascular abnormality...

Diabetes mellitus is a common metabolic disorder. Among various complications, diabetic neuropathy and peripheral vascular disorders are closely associated with diabetic foot ulcers (DFUs). Lower extremity ulcers and amputations are ongoing problems among individuals with diabetes. There are several classification systems for DFUs; however, no prognostic system has to date been accepted as the gold standard or the optimum prediction tool for amputations. A retrospective study was designed. Demographic data and baseline laboratory data were gathered and scored or evaluated using five representative DFU classification systems...

Diabetic foot ulcers (DFUs) are one of the most common indications for hyperbaric oxygen treatment (HBOT). The role of HBOT in DFUs is often debated. Recent evidence based guidelines, while recommending its use, urge further studies to identify the patient subgroups most likely to benefit from HBOT. A recent study in Diabetes Care aimed to assess the efficacy of HBOT in reducing the need for major amputation and improving wound healing in patients with chronic DFUs. In this study, patients with Wagner grade 2-4 diabetic foot lesions were randomly assigned to have HBOT (30 sessions/90 min/244 kPa) or sham treatment (30 sessions/90 min/air/125 kPa)...

BACKGROUND: Diabetic Charcot neuroarthropathy (DCN) is a devastating complication for people with diabetes mellitus. The failure to diagnose DCN and institute treatment in the acute phase leads to permanent deformity and significant morbidity. There is a paucity of data on the prevalence and characteristics of patients who have developed this complication of diabetes. AIMS: To determine the prevalence, clinical characteristics and outcomes of patients with DCN from 2006 to 2012...

Phlebology is not a specialty for its own in Italy. Phlebological patients are treated by vascular and general surgeons, dermatologists, phlebologists, angiologists, internists and even general practitioners. Even tough guidelines present a series of recommendations based on evidence-based medicine, guidelines may also be a tool to unify the diagnostic and therapeutic approach in a vast medical field like phlebology. Since vascular surgeons and phlebologists are particularly involved in phlebology-related pathologies the scientific societies of the Italian Society of Phlebology (SIF) and the Italian Society for Vascular and Endovascular Surgery (SICVE) decided to cooperate for the preparation of phlebo-lymphological guidelines...

During prolonged hypoxic conditions, endothelial cells change their gene expression to adjust to the low oxygen environment. This process is mainly regulated by the hypoxia-inducible factors, HIF-1α and HIF-2α. Although endothelial cells do not form sprouts during prolonged hypoxic culturing, silencing of HIF-2α partially restores sprout formation. The present study identifies novel HIF-2α-target genes that may regulate endothelial sprouting during prolonged hypoxia. The gene expression profile of primary human microvascular endothelial cells (hMVECs) that were cultured at 20 % oxygen was compared to hMVECs that were cultured at 1 % oxygen for 14 days by using genome-wide RNA-sequencing...

AIM OF THE STUDY: The coverage of ischiatic pressure ulcers is characterized by a significant recurrence rate (8-64% depending on the series). It therefore seems necessary to introduce the concept of saving in the use of muscle flaps available to avoid being in a situation of therapeutic impasse. The gluteus maximus inferior split-muscle flap allows a tailored coverage to the ischiatic pressure ulcers grade IV with skin defect less than 8cm after surgical debridement. It is associated with an advancement-rotation skin flap removed above the sub-gluteal fold...

BACKGROUND: Mesenchymal stem cell (MSC) transplantation is an effective treatment therapy for ischemic ulcers. However, in high-glucose microenvironment, the original inflammation-inhibiting function of MSCs leads to turns into secreting large amounts of inflammatory mediators, such as tumor necrosis factor alpha, for example, which decreases their capacity and becomes poor quality stem cells over inflammation cells for diabetic foot ulcers repair in the healing of diabetic foot ulcers...

BACKGROUND: Intractable chronic wounds share the basic problem of the environment being unfavorable for wound healing and prone to infection, inflammation, and recurrences. Microsurgical flap provides a healthy, well-vascularized normal tissue to compromised intractable environment, and promotes wound healing. In this report, we present the results of microsurgical flaps used for the reconstruction of chronic intractable conditions including chronic ulcer with an ischemic environment and pathologic lesions with a congestive environment...

Keratocytes, corneal resident cells in the corneal stroma, exist between collagen lamellae and maintain the corneal stromal structure. When the corneal stroma is damaged, keratocytes are transformed to myofibroblasts to aid corneal wound healing by phagocytizing debris. Keratocytes and extracellular collagen influence each other because keratocytes cultured in a 3D collagen gel undergo morphological changes and keratocytes produce metalloproteases that degrade extracellular collagen. IL-1 and plasminogen are critical mediators for collagen degradation...
