Ghrelin, an acylated 28-amino acid polypeptide, was primary isolated from the stomach, and the stomach is a main source of circulating ghrelin. Ghrelin strongly and dose-dependently stimulates release of growth hormone from the anterior pituitary, as well as increases food intake and fat deposition. Previous studies showed that ghrelin exhibits protective and therapeutic effect in different parts of the gastrointestinal system, including the oral cavity. The aim of present study was to examine the role of growth hormone and insulin-like growth factor-1 (IGF-1) in the healing of gingival ulcers...

OBJECTIVE: Oral mucositis (OM) caused by infection facilitated by myelosuppression and immunosuppression can be controlled through oral care. We investigated changes in oral anaerobic bacterial flora during the onset of OM with hematopoietic stem cell transplantation (HSCT). METHODS: This study included 19 patients who underwent HSCT. All received professional oral care before initiating the preparative regimen. We assessed OM, oral health and obtained microbial samples from the oral cavity during 5 assessment points: before initiating the preparative regimen; the day before HSCT (day 1); and at 7, 14, and 30 days after HSCT...

BACKGROUND: Major risk factors for oral squamous cell carcinoma (SCC) are tobacco smoking, a betel quid chewing habit, and heavy alcohol consumption. However, around 15% of oral SCCs cannot be explained by these risk factors. Although oral SCC associated with dental implants is quite rare, there has been a recent gradual accumulation of reports about it. Here, we report a case of primary peri-implant oral intra-epithelial neoplasia/carcinoma in situ (OIN/CIS) in a woman without the major risk factors for oral SCC...

As the largest interface between the outside and internal milieu, the intestinal epithelium constitutes the first structural component facing potential luminal threats to homeostasis. This single-cell layer is the epicenter of a tightly-regulated communication network between external and internal factors which converge to prime defensive responses aimed at limiting antigen penetration and the maintenance of intestinal barrier function. The defensive role developed by intestinal epithelial cells (IEC) relies largely on the variety of receptors they express at both extracellular (apical and basolateral) and intracellular compartments, and the capacity of IEC to communicate with immune and nervous systems...

Although radiation-based treatment for nasopharyngeal cancer may achieve excellent long term oncologic results, late effects of therapy may lead to soft tissue radionecrosis and velopharyngeal insufficiency (VPI). Repair of these oro- and nasopharyngeal defects presents a complex reconstructive challenge. We present a case of a long-term survivor treated with chemoradiotherapy for nasopharyngeal cancer who developed progressive dysphagia, velopharyngeal insufficiency, and radionecrosis of the nasopharynx and soft palate, leading to tracheostomy and gastrostomy tube dependence...

BACKGROUND: Fructo-oligosaccharides (FOS) are prebiotic agents with immunomodulatory effects involving improvement of the intestinal microbiota and metabolome. In this study, we investigated the cellular mechanisms through which FOS modulate intestinal antigen-specific CD4+ T cell responses in food allergy, using OVA23-3 mice. METHODS: OVA23-3 mice were fed an experimental diet containing either ovalbumin (OVA) or OVA and FOS for 1 week. Body weight and mucosal mast cell protease 1 in the serum were measured as the indicator of intestinal inflammation...

BACKGROUND: Clinical role of low-dose aspirin (LDA) in pathogenesis of gastroesophageal reflux disease is by far controversial. This can be attributed to the paucity of basic research detailing the mechanism of LDA-induced esophageal mucosal injury (EI) on underlying chronic acid reflux esophagitis (RE). AIM: The aim of this study was to clarify the effect of LDA on chronic RE in rats. METHODS: Esophagitis was induced in 8-week-old male Wistar rats by ligating the border between forestomach and glandular portion with a 2-0 silk tie and covering the duodenum with a small piece of 18-Fr Nélaton catheter...

Extracolonic involvement of the gastrointestinal tract is extremely uncommon in ulcerative colitis (UC) and rarely found in the upper gastrointestinal tract or in postoperative cases since it typically responds to steroids. Here we report a case of UC complicated by extensive ileal inflammation that was refractory to steroids. A 20-year-old man was diagnosed with UC of typical pancolitis without ileal involvement and started treatment with pH-dependent mesalazine and oral prednisolone. Although his symptoms transiently resolved, the condition flared when the steroid dose was tapered down...

The peripheral T-cell lymphomas (PTCL) are a group of rare malignancies characterized by chemotherapy insensitivity and poor prognosis. Romidepsin and pralatrexate were approved by the U.S. FDA for patients with relapsed/refractory PTCL, exhibiting response rates of 25% and 29% respectively. Based on synergy of the combination in preclinical models of PTCL, we initiated a phase I study of pralatrexate plus romidepsin in patients with relapsed/refractory lymphoma (ClinicalTrials.gov (NCT01947140)). This was a single institution dose-escalation phase I study of pralatrexate plus romidepsin designed to determine the dose limiting toxicities (DLT), maximum tolerated dose (MTD), pharmacokinetic profile and response rates...

Oral lichen planus (OLP), a well-known entity, is often neglected; however, its assessment is considered essential for evolving future strategies for treatment. Thirty-three patients with OLP from 200 consecutive patients with oral mucosal lesions were studied according to demography. Tobacco chewing, smoking, and alcohol intake were recorded. Examination of the oral cavity, using a head light and tongue depressor, was undertaken to define the morphology of the lesion(s). Colored photographs were an essential part of the process...

RATIONALE: Bromadiolone, often called a super-warfarin, is a potent rodenticide with long half-life. Skin and mucosal bleeding is the most common clinical manifestations of its intoxication. Bromadiolone intoxications in adults and children have been reported, but this phenomenon is rarely seen in fetuses. This paper presents a case of neonate with massive intracranial hemorrhage mediated by bromadiolone intoxication, highlighting that the bromadiolone is potentially lethal to the fetus...

PURPOSE: Oral lichen planus (OLP) is an autoimmune skin and mucosal disorder. The range of malignant transformation in OLP varies between 0.1-3%. p53 is a tumor suppressor protein. Defective p53 could allow abnormal cells to proliferate, resulting in cancer. p53 plays an important role in cell cycle control and apoptosis and loss of p53 function has been demonstrated in about half of all human cancers. The purpose of the study was to investigate the malignant potential of OLP on the basis of p53 expression and to correlate p53 expression with clinical and histopathological features of OLP...

Oral epithelial cells discriminate between pathogenic and non-pathogenic stimuli, and only induce an inflammatory response when they are exposed to high levels of a potentially harmful microorganism. The pattern recognition receptors (PRRs) in epithelial cells that mediate this differential response are poorly understood. Here, we demonstrate that the ephrin type-A receptor 2 (EphA2) is an oral epithelial cell PRR that binds to exposed β-glucans on the surface of the fungal pathogen Candida albicans. Binding of C...

Chlamydia has been detected in the gastrointestinal tracts of humans and animals. We now report that gastrointestinal Chlamydia muridarum is able to induce robust transmucosal protection in mice. C. muridarum colonization in the gastrointestinal tract correlated with both a shortened course of C. muridarum genital infection and stronger protection against subsequent genital tract challenge infection. Mice pre-inoculated intragastrically with C. muridarum became highly resistant to subsequent C. muridarum infection in the genital tract, resulting in prevention of pathology in the upper genital tract...

The World Health Organization encourages "the development of oral formulations to simplify their transport, storage and administration in poor countries", and to "facilitate an effective immunization program to prevent sexually transmitted hepatitis B". Thus, two distinct and promising delivery systems were developed: recombinant hepatitis B surface antigen (HBsAg) encapsulated into alginate-coated chitosan particles (AlgChiPs) and into glucan particles (GPs) mainly composed of β-1,3-D-glucan. In vitro preliminary studies showed that both could be internalized by peripheral blood mononuclear cells and murine Peyer's patches, an imperative aspect regarding oral immunization...
