ABSTRACT
BACKGROUND: Cow's milk allergy is a common food allergy in childhood and no effective preventive or curative treatment is available. This study aimed at comparing single short-chain galacto- (scGOS), long-chain fructo- (lcFOS) or pectin-derived acidic oligosaccharides (pAOS) and/or mixtures of scGOS/lcFOS (GF) or scGOS/lcFOS/pAOS (GFA) to prevent or treat food allergy. METHODS: In the preventive protocol, C3H/HeOuJ mice were fed diets containing single oligosaccharides or mixtures GF or GFA throughout the study protocol. In the treatment protocol, GF or GFA was provided for 4 wk starting after the last sensitization. The allergic skin response and anaphylaxis scores were determined, after oral challenge whey-specific immunoglobulins were measured, and qPCR for T-cell markers and Foxp3 counts using immunohistochemistry were performed on the small intestine and colon. RESULTS: Only in the preventive setting, the GF or GFA mixture, but not the single oligosaccharides, reduced the allergic skin response and whey-IgG(1) levels in whey-sensitized mice, compared to the control diet. Both GF and GFA increased the number of Foxp3+ cells in the proximal small intestine of whey - compared to sham-sensitized mice. Expression of Th2 and Th17 mRNA markers increased in the middle part of the small intestine of whey-sensitized mice, which was prevented by GF. By contrast, GFA enhanced Tbet (Th1), IL-10 and TGF-ß mRNA expression compared to GF which was maintained in the distal small intestine and/or colon. CONCLUSIONS: Dietary supplementation with scGOS/lcFOS or scGOS/lcFOS/pAOS during sensitization, both effectively reduce allergic symptoms but differentially affect mucosal immune activation in whey-sensitized mice.

For the care of the elderly, specific geriatric care facilities in hospitals and specialized rehabilitation centers have been established in the last 20 years throughout Germany. In addition, trauma surgery departments in hospitals and clinics also provide comprehensive care for trauma patients. The present requirements catalog was developed with the aim to ensure the standardization and quality assurance of these care facilities. Thus, the structural basics and, in particular, the structured cooperation between geriatrics and trauma surgery are described and defined in terms of structure, process, and outcome quality. The Bundesverband Geriatrie, the Deutsche Gesellschaft für Geriatrie, and the Deutsche Gesellschaft für Gerontologie und Geriatrie offer documentation for external and internal use and evaluation of the structures and processes for certification of geriatric trauma centers. Prerequisite for certification is to meet the technical requirements defined in the requirements catalogue or documents derived from it, and proof of a quality management system according to ISO 9001.

BACKGROUND: To cover future needs of specialised geriatric patient-centred care, existing structures need to be developed further. MATERIALS AND METHODS: Taking into account regional structures of providing care, the Federal Association of Geriatric Medicine in Germany developed the concept of Cross-Border Cooperation in Geriatric Medicine. RESULTS: This concept combines specific geriatric expertise provided by inpatient health care with specialised networking in ambulatory treatment of elderly with a typical geriatric profile. The objective is to provide geriatric patients with a holistic and specific care and case management that overcomes existing limitations.

BACKGROUND: Failing to meet the benchmark of 12 lymph nodes in resection specimens is an indication for adjuvant chemotherapy in stage II colon cancer. METHODS: Among consecutive eligible patients with pathologic stage II colon cancer treated at eight NCI-designated comprehensive cancer centers between September 1, 2005 and February 19, 2008, we analyzed receipt of adjuvant chemotherapy, with less than 12 versus 12+ lymph nodes removed and examined the primary explanatory variable of interest. RESULTS: Among 258 patients, 46% received adjuvant chemotherapy. An oxaliplatin-containing regimen was used 67% of the time. Younger age (<50 years, P < 0.001), presence of lymphovascular invasion (P = 0.007), and higher T stage (P = 0.007) were independently associated with adjuvant chemotherapy use. There was significant inter-institutional variability in practice with the proportion receiving treatment ranging from 17% to 64% (P < 0.05). Notably, presence of less than 12 lymph nodes in the surgical specimen was a strong predictor of treatment (P = 0.008). CONCLUSIONS: Adjuvant chemotherapy use after resection of stage II colon cancer is common, but by no means standard practice at National Comprehensive Cancer Network (NCCN) institutions. More attention to achieving the recommended benchmark for lymph node dissection has the potential to decrease exposure to the toxicity of adjuvant treatment.

Due to its immunomodulatory and anti-inflammatory properties glucocorticosteroids have proved to be highly efficacious in patients with inflammatory bowel disease. However, because of the risk of side-effects, the dose and duration of therapy with systemically acting glucocorticosteroids have to be restricted. Recently the use of topically acting glucocorticosteroids has attracted great interest. Among the various topically acting glucocorticosteroids budesonide has emerged as the most promising. Budesonide is highly potent, is readily water-soluble and has low systemic bioavailability, thus reducing the risk of corticosteroid-related side-effects. When given as enema to patients with proctitis or proctosigmoiditis, the efficacy of budesonide is greater than that of placebo and equal to that of prednisolone or 5-aminosalicylic acid enemas. In an enteric-coated formulation budesonide is more effective than placebo in achieving and maintaining remission in patients with ileocecal Crohn's disease. Although corticosteroid-related side-effects are rare, some suppression of the hypothalamic-pituitary-adrenal axis may occur.

Oxygen-derived free radicals may contribute to intestinal tissue damage in inflammatory bowel disease. The concentrations of metallothionein and superoxide dismutase, two copper and zinc containing proteins involved in the scavenging of free radicals; were previously found to be decreased in the intestinal mucosa of patients with this disorder. The plasma zinc concentration is often decreased also in these patients. Since zinc is reported to be an efficient inducer of metallothionein synthesis, and probably of superoxide dismutase, we evaluated the effect of oral zinc supplementation on metallothionein and superoxide dismutase levels in patients with inflammatory bowel disease. Fourteen patients with inactive to moderately active inflammatory bowel disease received oral zinc supplementation (300 mg zinc aspartate, equal to 60 mg elemental zinc per day) for 4 weeks in a placebo-controlled double-blind cross-over trial. The plasma zinc concentration of these patients was low at the start of the study (12.2 +/- 1.7 mumol/L, P < 0.05), when compared to that of 22 healthy controls (13.6 +/- 2.3 mumol/L), but increased (P < 0.05) towards the levels of controls during the supplementation period (13.3 +/- 2.5 mumol/L). The concentrations of metallothionein and superoxide dismutase in plasma and in erythrocytes did not change in relation to the supplementation. The metallothionein concentration in both inflamed and non-inflamed intestinal mucosa was slightly higher after zinc supplementation but the superoxide dismutase concentration in the tissue was not altered. The histological inflammation score of intestinal biopsies, plasma albumin levels, and the disease activity index of the patients did not change during the study.(ABSTRACT TRUNCATED AT 250 WORDS)

In a randomized, double-blind study, the effects of individualized homoeopathy in patients suffering from proctocolitis were investigated. The study was controlled against conventional therapy and placebo. Individually indicated homoeopathic medicines were prescribed in the 30c, 200c or 1.000c potencies. The researches did not succeed in attracting sufficient numbers of participants to arrive at statistically significant conclusions. The total number of patients in the three combined groups was only 20, which was far below the target figure. The causes of this are discussed. Bowel habit and subjective parameters were assessed by a weekly health calendar. This calendar had not been previously validated. The conventional group scored best: eight out of ten patients completed the year of research and improved both with regard to their proctocolitis and their general well-being
