The association of Helicobacter pylori eradication with the occurrence of renal dysfunction in patients with peptic ulcer diseases is still unclear. This study aimed to clarify the relevance of H. pylori eradication to the occurrence of chronic kidney diseases in patients with peptic ulcer diseases. Data that were available from 2000-2011 were extracted from the National Health Insurance Research Database in Taiwan, and all patients with peptic ulcer diseases (n = 208 196) were screened for eligibility. We divided randomly selected patients into an H...

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...

Inflammatory bowel disease is a chronic and progressive inflammatory intestinal disease that includes two major types, namely ulcerative colitis and Crohn's disease (CD). CD is characterized by intestinal epithelial hyperplasia and inflammatory cell infiltration. Transfer of CD25(-)CD45RB(hi)CD4(+) (naïve) T cells into immunodeficiency mice induces autoimmune colitis with pathological lesions similar to CD and loss of body weight 4 weeks after cell transfer. However, weight loss neither has sufficient sensitivity nor totally matches the pathological findings of CD...

BACKGROUND: Helicobacter pylori (H pylori) is a common gastric pathogen which is associated with chronic gastritis, peptic ulcer, and gastric cancer. It has worldwide distribution with higher incidence in developing countries. Gemifloxacin is a fluoroquinolone antibiotic with documented in vitro activity against H pylori. Considering that there is no clinical data to verify gemifloxacin efficacy in H pylori eradication, this pilot clinical trial was designed. METHODS: This prospective pilot study was performed during February 2014 to February 2015...

H. pylori cytotoxin associated antigen A (CagA) plays a significant role in the progression of gastric cancer but their effect on fucosylation to develop gastric cancer is unknown. Fucosyltransferase IV (FUT4) is the key enzyme for synthesis of LewisY (LeY) carried by glycoproteins and glycolipids on the cell membrane. Herein, we compare the expression of CagA, p-EGFR, FUT4 and LeY in gastritis (n = 128, 176), gastric ulcer (n = 174, 213), and gastric cancer (n = 323, 261) tissue and serum samples, respectively by IHC and ELISA...

We present a case of a 65-year-old man with cutaneous T-cell lymphoma treated with radiation therapy and an allogeneic hematopoietic stem cell transplant from his human leukocyte antigen-matched brother. Engraftment was successful, but the patient went on to develop painful, radiation-induced ulcers. The ulcers were fat-allografted using liposuctioned fat from his brother because of the patient's unique chimeric state. Postprocedure follow-up revealed epithelialization of the ulcer sites and significant improvement in neuropathic pain...

INTRODUCTION: Currently, venography is the standard diagnostic method to examine veins before implementing access, which is invasive in nature. Computerized tomography venography (CTV) can simultaneously indicate deep and superficial venous systems in the upper extremity and their relation to the surrounding anatomical structures; however, its diagnostic value in the detection of central venous disease has yet to be defined. The aim of this study was to determine the diagnostic value of CT venography compared to venography in the diagnosis of stenosis and the occlusion of subclavian veins and the superior vena in renal failure patients...

The stomach of pigs at slaughter age is often colonized by Helicobacter (H.) suis, which is also the most prevalent gastric non-H. pylori Helicobacter (NHPH) species in humans. It is associated with chronic gastritis, gastric ulceration and other gastric pathological changes in both hosts. Parietal cells are highly specialized, terminally differentiated epithelial cells responsible for gastric acid secretion and regulation. Dysfunction of these cells is closely associated with gastric pathology and disease...

BACKGROUND: Chronic venous insufficiency, in its final stage can cause venous ulcers. Venous ulcers have a prevalence of 0.5 % to 0.8 % in the general population, and increases starting at 60 years of age. This condition often causes increased dependency in affected individuals, as well as a perceived reduced quality of life and family overload. Local Treating chronic venous ulcers has 2 components: topically healing the ulcer and controlling the venous insufficiency. There is evidence that compressive therapy favours the healing process of venous ulcers...

OBJECTIVE: Diabetic foot osteomyelitis (DFO) is difficult to diagnose in the presence of Charcot's neuroarthropathy (CN) and bone biopsy is not always possible. We aimed to assess the efficacy of PET/computed tomography using F-fluoride (F-fluoride PET/CT) and fluorine-18-fluorodeoxyglucose-labeled autologous leukocytes (F-FDG-LL PET/CT) in comparison with contrast-enhanced MRI (CEMRI) for the detection of DFO. PATIENTS AND METHODS: Thirty-two patients with chronic CN and foot ulcer suspected of having DFO were prospectively evaluated...

Infection with Helicobacter pylori is the strongest risk factor for the development of chronic gastritis, gastric ulcer and gastric carcinoma. The majority of the H. pylori-infected population remains asymptomatic, and only 1% of individuals may progress to gastric cancer. The clinical outcomes caused by H. pylori infection are considered to be associated with bacterial virulence, genetic polymorphism of hosts as well as environmental factors. Most H. pylori strains possess a cytotoxin-associated gene (cag) pathogenicity island (cagPAI), encoding a 120-140 kDa CagA protein, which is the most important bacterial oncoprotein...

: RISE-SSc is a randomized, double-blind, placebo-controlled phase 2 study investigating the efficacy and safety of riociguat in patients with diffuse cutaneous systemic sclerosis (dcSSc). Based on positive results from riociguat trials in patients with pulmonary hypertension and chronic thromboembolic pulmonary hypertension in combination with the known antiproliferative and antifibrotic effects seen in animal models, patients with SSc may benefit from treatment with riociguat. Patients with SSc meeting the ACR/EULAR systemic sclerosis classification criteria with diffuse cutaneous SSc (dcSSc) subset per LeRoy criteria, and a disease duration of less than or equal to 18 months will be randomized to placebo or riociguat 0...

Chronic soft tissue wounds of the lower limbs are debilitating, painful and often unresponsive to advanced dressing treatments. Extracorporeal shock wave therapy (ESWT) could represent an alternative treatment. Ten patients with chronic soft tissue wounds of the legs, unresponsive to advanced dressing treatments for more than 3 mo, underwent three defocused ESWT sessions at 72-h intervals. In every session, the sum of 300 standard pulses + 100 pulses per square centimeter was applied at 0.15 mJ/mm(2) and 4 Hz over the edge of the wound...

BACKGROUND: A prominent role of hair follicle-derived cells in epidermal wound closure is now well established but clinical translation of basic research findings is scarce. Although skin punch grafts have been used as a therapeutic intervention to improve healing of chronic leg ulcers, they are normally harvested from nonhairy areas, thus not taking advantage of the reported role of the hair follicle as a wound-healing promoter. OBJECTIVE: We sought to substantiate the role of hair follicles in venous leg ulcer healing by transplanting hair follicle-containing versus nonhairy punch grafts...

OBJECTIVES: Behçet's disease (BD), an auto-inflammatory vasculitis with oro-genital ulcerations, skin lesions and uveitis, is regarded as T cell mediated. A successful trial with rituximab suggests an additive role for B cells in the pathogenesis. Therefore, we studied B cell abnormalities in BD patients and the effect of TNF-blocking therapy. METHODS: B cells in blood (n = 36) and tissue (n = 6) of BD patients were analysed with flow cytometry and/or immunohistochemistry and compared with healthy controls (n = 22)...

A wound is damage of a tissue usually caused by laceration of a membrane, generally the skin. Wound healing is accomplished in three stages in healthy individuals, including inflammatory, proliferative, and remodeling stages. Healing of wounds normally starts from the inflammatory phase and ends up in the remodeling phase, but chronic wounds remain in an inflammatory stage and do not show progression due to some specific reasons. Chronic wounds are classified in different categories, such as diabetic foot ulcer (DFU), venous leg ulcers (VLU) and pressure ulcer (PU), surgical site infection (SSI), abscess, or trauma ulcers...

While the problem of Pressure Ulcers (PU) in adults has received a great deal of attention, far less is known about PUs in neonates and children. The overall health status of children is generally better and multi-morbidity is limited to a small percentage of patients, like very low term neonates (born before 32 weeks of gestation age), newborns with congenital abnormalities, genetic disorders, perinatal distress syndrome or children with a limited immunity. Survival rates of both critically and chronically ill neonates, infants and children have improved dramatically in recent years, introducing new challenges for medical and nursing care...

Limbal stem cell deficiency is predominantly caused by severe eye burns resulting in a decreased or a complete ablation of the regenerative potential of these stem cells. The inability to reconstruct the corneal epithelium further leads conjunctivalization of the gimbal-epithelial barrier. These abnormalities collectively result in the progressive opacification of the cornea responsible for blindness that is driven by chronic corneal ulceration and neovascularization. The underlying pathology of the cornea affects the homeostasis of the neighboring conjunctiva, eyelids, and tear film...
