This study reports on the case of an elderly patient, with diabetes, and a bullous wound on the left big toe that led to an amputation of the first and second left toes. The amputation was because of deep injury as it was not able to heal with a conventional treatment. After completing the normal treatment and the removal of a bacterial infection in the lesion, the patient underwent a treatment that was based on a hydrogel gel (0.9% saline solution) and hyperbaric oxygen therapy (HBOT). After 60 sessions of the therapy, almost complete closure of the wound was observed. There were no reports of discomfort or infection during the treatment. After seven months of treatment almost complete healing was observed with no infection. This treatment appears to be effective and should be recommended for the treatment of DFUs.

Hericium erinaceus is typically used in traditional Chinese medicine for mucosal protection, healing of gastric ulcers, and treatment of gastritis. We purified from the cultured mycelia of H. erinaceus a polysaccharide with anti-gastric ulcer and antigastritis activity, but its effects on gastric malignancy have not been elucidated. We examined the differential effects of this purified polysaccharide, named EP-1, on the human gastric (GES-1) cell line and a precancerous cell line (MC) that was transformed from GES-1 using N-methyl-N'-nitro-N-nitrosoguanidine. We observed that the polysaccharide potently induced cell apoptosis and cell cycle arrest at the G0/G1 phase in the MC cell line but did not have any effect on the GES-1 cell line at the same doses. Further mechanistic studies revealed that the polysaccharide exerted its activity through an apoptosis-associated pathway by modulating the expression of Bax, Bcl-2, and caspase-3. Differential effects of the polysaccharide on the GES-1 and MC cell lines indicate that the polysaccharide was effective in preventing gastric cancer progression.

BACKGROUND/AIMS: To test the impact of vitamin C supplementation on triple therapy for H. pylori eradication. METHODOLOGY: A total of 171 H. pylori-infected patients were randomized to receive different one-week triple therapies, including 20 mg omeprazole, 1 g amoxicillin, plus the following twice daily: (1) 250 mg clarithromycin (C250 group, n=55); (2) 250 mg clarithromycin and 500 mg vitamin C (V-C250 group, n=61); (3) 500 mg clarithromycin (C500 group, n=55). Six weeks after treatment, the success of H. pylori eradication was assessed by a 13C-urea breath test. Each collected H. pylori strain was defined as either clarithromycin susceptible or resistant by E-test. RESULTS: The demographic background, clarithromycin susceptibility of H. pylori, and drug compliance were similar among the three groups (p=NS). For clarithromycin susceptible infection, the V-C250 group had a higher eradication rate than the C250 group (ITT: 85% vs. 68% and PP: 90% vs. 73%, p = 0.03), but had an equivalent rate to the C500 group (p=NS). For clarithromycin resistant infection, all three groups had a similarly poor eradication rate of less than 34%. CONCLUSIONS: Adding vitamin C to one-week triple therapy can reduce the dosage of clarithromycin, but preserve the high eradication efficacy for clarithromycin susceptible H. pylori infection.

BACKGROUND:Digital and leg ulcers are extremely painful, hard to heal manifestations of systemic sclerosis (SSc). Many treatments have been tried for these challenging complications, but use of hyperbaric oxygen therapy (HBOT) is very limited. HBOT has been used as an adjunctive therapy for treating chronic wounds, and nonhealing SSc wounds, which have a hypoxic nature, may also benefit from it.

METHODS:This is a retrospective analysis of six SSc patients who underwent HBOT for their ulcers. Patient demographics, ulcer properties, and details of treatments were evaluated.

RESULTS:Three patients had digital ulcers, and the other three had leg ulcers. Three patients (two leg ulcers and one digital ulcer) had bilateral lesions. All patients had been treated for at least one and a half months with various modalities. After HBOT was applied, four patients' ulcers healed completely and two patients had near-complete healing. Amputation was not required for any.

CONCLUSION:This case series, which has the largest patient population up to present, shows adjunctive HBOT may be helpful in the treatment of SSc ulcers.

Alendronate causes serious gastrointestinal adverse effects. We aimed to investigate if free radicals have any role in the damage induced by alendronate and if melatonin or omeprazole is protective against this damage. Rats were administered 20 mg/kg alendronate by gavage for 4 days, either alone or following treatment with melatonin or omeprazole. On the last day, following drug administration, pilor ligation was performed, and 2 hr later rats were killed and stomachs were removed. Gastric acidity and tissue ulcer index values, lipid peroxidation, and myeloperoxidase and glutathione levels, as well as the histologic appearance of the stomach tissues, were determined. Chronic oral administration of alendronate induced significant gastric damage, increasing lipid peroxidation and myeloperoxidase activity, while tissue glutathione levels decreased. Treatment with omeprazole or melatonin prevented this damage as well as the changes in biochemical parameters, and melatonin appeared to be more efficient than omeprazole in protecting the mucosa. Intraperitoneal administration of alendronate did not cause much gastric irritation. Findings of the present study suggest that alendronate induces oxidative gastric damage by a local irritant effect and that melatonin and omeprazole are protective against this damage due to their antioxidant properties.

A new technique of low-frequency modulated electric current therapy, SCENAR therapy, was used in treatment of 103 patients with duodenal ulcer (DU). The influence of SCENAR therapy on the main clinical and functional indices of a DU relapse was studied. It was shown that SCENAR therapy, which influences disturbed mechanisms of adaptive regulation and self-regulation, led to positive changes in most of the parameters under study. Addition of SCENAR therapy to the complex conventional pharmacotherapy fastened ulcer healing, increased the effectiveness of Helicobacter pylori eradication, and improved the condition of the gastroduodenal mucosa.
