Allergic rhinitis, a frequently occurring immunological disorder affecting men, women and children worldwide, is a state of hypersensitivity that occurs when the body overreacts to a substance such as pollen, mold, mites or dust. Allergic rhinitis exerts inflammatory response and irritation of the nasal mucosal membranes leading to sneezing; stuffy/runny nose; nasal congestion; and itchy, watery and swollen eyes.

BACKGROUND: A vegetarian diet is considered to promote health and longevity and reduce the risk of cardiovascular diseases and cancer. However, a vegetarian diet may be deficient in some nutrients. Exclusion of animal products in vegetarian diets may affect the status of certain B-vitamins, and further cause the rise of plasma homocysteine concentration. OBJECTIVE: The nutritional status of various B-vitamins (B(1), B(2), B(6), B(12), folic acid) and the concentration of homocysteine in blood plasma of omnivores (n = 40), vegetarians (n = 36) and vegans (n = 42) in Austria was evaluated.

Our previous studies have shown that riboflavin has activity against Plasmodium falciparum asexual-stage parasites in vitro. In the present study we examine the gametocytocidal activity of riboflavin and the interaction of riboflavin with some commonly used antimalarial drugs against the asexual forms of P. falciparum in vitro. The addition of riboflavin to P. falciparum cultures killed gametocytes at all stages, even those at late stages (III to V), which are not affected by many of the commonly used antimalarials.

OBJECTIVE: To study the chemical constituents in rhizome of Matteuccia struthiopteris. METHOD: The compounds were isolated by normal phase silica gel chromatography. The structures were identified by physical and spectral data. RESULT: Six compounds were isolated and identified as woodwardic acid (1), ergost-6,22-diene-3beta,5alpha,8alpha-triol (2), apigenin (3), riboflavin (4), 4-O-beta-D-glucopyranosyl-p-coumaric acid (5), 4-O-beta-D-glucopyranosylcaffeic acid (6). CONCLUSION: All the compounds were obtained from this plant for the first time.

BACKGROUND: Bariatric surgery is widely performed to induce weight loss. OBJECTIVE: The objective was to examine changes in vitamin status after 2 bariatric surgical techniques. DESIGN: A randomized controlled trial was conducted in 2 Scandinavian hospitals. The subjects were 60 superobese patients [body mass index (BMI; in kg/m(2)): 50-60]. The surgical interventions were either laparoscopic Roux-en-Y gastric bypass or laparoscopic biliopancreatic diversion with duodenal switch. All patients received multivitamins, iron, calcium, and vitamin D supplements.

BACKGROUND: Moderate riboflavin deficiency is prevalent in certain population groups in affluent countries, but the functional significance of this deficiency is not clear. Studies have indicated a role for riboflavin in the absorption and use of iron. OBJECTIVE: We investigated the effect of riboflavin supplementation on hematologic status in a group of moderately riboflavin-deficient women aged 19-25 y in the United Kingdom.

BACKGROUND: Migraine and tension headache are common--affecting up to 10% and 40% of the Australian population respectively--and result in significant reduction in social activities and work capacity for sufferers. OBJECTIVE: This article considers the evidence for the use of a range of complementary therapies and treatment in the prevention and management of both migraine and tension headache. DISCUSSION: Migraine and tension headache can have many precipitating factors. Considering dietary and environmental factors complements a migraine/headache consultation.
