Fabry disease is an X-linked lysosomal storage disorder caused by a deficiency of α-galactosidase A (α-gal A), leading to the progressive accumulation of glycosphingolipids. Classical hemizygous males usually present symptoms, including pain and paresthesia in the extremities, angiokeratoma, hypo- or anhidrosis, abdominal pain, cornea verticillata, early stroke, tinnitus, and/or hearing loss, during early childhood or adolescence. Moreover, proteinuria, renal impairment, and cardiac hypertrophy can appear with age...

BACKGROUND AND STUDY AIMS: Obscure gastrointestinal bleeding (OGIB) is defined as bleeding of unknown origin that persists or recurs after an initial negative investigation. Identifying the source of OGIB represents a diagnostic challenge that is frequently focused on visualizing the small intestine. Conventional diagnostic methods, such as push enteroscopy, small-bowel follow-through, radionuclide scanning, and angiography, each exhibit inherent limitations. Double balloon enteroscopy (DBE) was designed specifically to evaluate the entire small bowel...

BACKGROUND: Peripheral arterial occlusive disease (PAOD) is a common cause of morbidity and mortality due to cardiovascular disease in the general population. Although numerous treatments have been adopted for patients at different disease stages, no option other than amputation is available for patients presenting with critical limb ischaemia (CLI) unsuitable for rescue or reconstructive intervention. In this regard, prostanoids have been proposed as a therapeutic alternative, with the aim of increasing blood supply to the limb with occluded arteries through their vasodilatory, antithrombotic, and anti-inflammatory effects...

Patients with non-transfusion-dependent thalassemia (NTDT) experience many clinical complications despite their independence from frequent transfusions. Morbidities in NTDT stem from the interaction of multiple pathophysiological factors: ineffective erythropoiesis, iron overload (IOL), and hypercoagulability. Ineffective erythropoiesis and hemolysis are associated with chronic hypoxia and a hypercoagulable state. The latter are linked to a high prevalence of thromboembolic and cerebrovascular events, as well as leg ulcers and pulmonary hypertension...

Diffuse dermal angiomatosis (DDA) is a rare reactive angioproliferation in the skin and considered to be a subtype in the group of cutaneous reactive angiomatoses. DDA is clinically characterized by livedoid patches and plaques with tender ulceration. Its histologic features are a reactive diffuse proliferation of bland endothelial cells and pericytes within the dermis, forming small capillary vessels. Previously described cases of DDA most commonly involved the limbs and were associated with a wide spectrum of predisposing comorbidities, especially advanced atherosclerotic vascular disease and arteriovenous fistula...

Gastric ulcer affects people worldwide, and its inefficacy and recurrence have fueled the search for new therapeutic strategies. Despite the well-known use of allantoin in medicines and cosmetic products, its effect has not yet been studied with regard to gastric ulcer. Hence, the aim of the present study was to explore the pharmaco-mechanistic efficacy of allantoin against commonly harmful agents that cause injuries to the stomach. Ethanol, indomethacin, and stress-induced gastric ulcer models were adopted, in addition to pylorus ligature, a quantification of vascular permeability, glutathione (GSH), gastric adhered mucus, prostaglandin (PGE2), pro-inflammatory cytokines levels, myeloperoxidase (MPO), and catalase (CAT) activities...

Mechanisms involved in melanoma invasiveness and metastasis are essential to understanding the behavior of this aggressive melanocytic skin cancer. The epithelial-mesenchymal transition (EMT) is considered fundamental for overcoming the in situ stage of melanoma and its proliferation beyond the basal membrane. Matrix metalloproteinases (MMPs) and their tissue inhibitors (TIMPs) are key molecules involved in EMT about whose expression in lentigo maligna (LM) and lentigo maligna melanoma (LMM) little has been studied so far...

Granzyme B (GzmB) is a serine protease emerging as an important mediator of skin injury, inflammation and repair. Found at low levels in healthy skin, GzmB is dramatically elevated in chronic disease and inflammatory skin disorders, including diabetic ulcers, hypertrophic scarring, autoimmune skin disorders, cutaneous leishmaniasis and aging skin. Traditionally known for its pro-apoptotic function, the role of GzmB in disease has been redefined due to the discovery of additional activities involving the cleavage of extracellular matrix proteins, epithelial barrier disruption, fibrosis, vascular permeability, anoikis, inflammation and autoimmunity...

INTRODUCTION: Behçet disease is a multisystemic chronic inflammatory disorder characterized by recurrent oral aphthous ulcers, genital ulcers, uveitis, and skin lesions. However, particularly part of patients would present cardiovascular involvements and vascular lesions could be the presenting sign of Behçet disease preceding classical symptoms. We presented a middle aged male patient, in whom abdominal aorta pseudoaneurysm was as the first leading sign to reveal Behçet disease, and with his coronary artery lesions progress through a 10-year period before Behçet disease was diagnosed...

Venous ulcers are deep wounds that are located predominantly on the lower leg. They are prone to infection and once healed have a high probability of recurrence. Currently, there are no effective measures to predict and prevent venous ulcers from formation. Hence, the goal of this work was to develop a Windkessel-based model that can be used to identify hemodynamic parameters that change between healthy individuals and those with wounds. Once identified, these parameters have the potential to be used as indicators of when internal conditions change, putting the patient at higher risk for wound formation...

BACKGROUND: Seeking treatment in a timely manner may prevent lower limb amputation subsequent to diabetic foot ulcers. Knowledge regarding the warning signs is one important factor that is related to the timely treatment seeking of patients with diabetic foot ulcers. However, there is no previous research on which aspects of such knowledge that patients with diabetes are lacking. PURPOSE: The aims of this study were to test the psychometric properties of a questionnaire that was designed to assess the knowledge of the warning signs of diabetic foot ulcer deterioration and to determine the knowledge of these warning signs among patients with a history of diabetic foot ulcers...
