Management of Crohn’s disease from efficacy, quality of life and health economic perspectives
The expectations of the physician and patient in the modern management of Crohn’s disease have moved on from alleviation of symptoms whenever relapses occur, to sustained maintenance of remission and mucosal healing. The majority of treatment costs are as a consequence of hospitalizations and surgery. These heightened therapeutic goals are leading to expectations that management costs will decrease. Health-related quality of life can be measured by validated disease-specific tools in Crohn’s disease, and such measurements are now forming common outcome measures in clinical trials of new therapies in Crohn’s disease. This review gives an overview of patient-focused management of Crohn’s disease and the rapid evolution in therapy, with pharmacoeconomic analysis where available.

title: Bioactive natural compounds for the treatment of gastrointestinal disorders.
abstract: Many healthy subjects and patients are taking natural bioactive products for the prevention and treatment of multiple conditions, including gastrointestinal disorders. Based on current evidence, the scientific validity of the use of many of these commercial compounds by the general public is severely limited, with quality control and regulatory issues continuing to be a concern. Nevertheless, there is sufficient preliminary data to warrant further research of these products in order to identify novel compounds for potential clinical use in addition to performing formal randomized controlled clinical trials of the commercial preparations.

title: Effects of Mn levels on resistance of Bacillus megaterium spores to heat, radiation and hydrogen peroxide.
abstract: To determine the effects of Mn levels in Bacillus megaterium sporulation and spores on spore resistance.



Bacillus megaterium was sporulated with no added MnCl(2) and up to 1 mmol l(-1) MnCl(2). The resultant spores were purified and loosely bound Mn removed, and spore Mn levels were found to vary c. 100-fold. The Mn level had no effect on spore γ-radiation resistance, but B. megaterium spores with elevated Mn levels had higher resistance to UVC radiation (as did Bacillus subtilis spores), wet and dry heat and H(2)O(2). However, levels of dipicolinic acid and the DNA-protective α/β-type small, acid-soluble spore proteins were the same in spores with high and low Mn levels.



Mn levels either in sporulation or in spores are important factors in determining levels of B. megaterium spore resistance to many agents, with the exception of γ-radiation.



The Mn level in sporulation is an important factor to consider when resistance properties of B. megaterium spores are examined, and will influence the UV resistance of B. subtilis spores, some of which are used as biological dosimeters.

title: Molecular characterization of rare bovine group A rotavirus G15P[11] and G15P[21] strains from eastern India: identification of simian SA11-like VP6 genes in G15P[21] strains
abstract: During a surveillance study (November 2001–March 2005), one rare G15P[11] and two rare G15P[21] bovine group A rotavirus strains were detected in diarrhoeic calves in Eastern India. Sequence analysis of the VP8*, VP6, NSP4 and NSP5 genes of the G15P[11] strain confirmed its bovine origin. Although the NSP4 and NSP5 genes of the two G15P[21] strains were of bovine origin, their VP6 genes shared higher nucleotide and amino acid identities with simian strain SA11 (92.5–93.1% and 98.5–98.7%) than bovine strains (88.5–88.9% and 97–97.2%), and by phylogenetic analysis, exhibited clustering with SA11, distantly related to bovine strains. All these pointed towards a possible reassortment event of VP6 gene between bovine and simian (SA11-like) strains. Therefore, the present study provided molecular evidence for bovine origin of G15 strains and revealed a rare instance of genetic diversity in the bovine VP6 gene, otherwise conserved in group A rotavirus strains from cattle.

title: Management of donors for heart and heart-lung transplantation.
abstract: The quality of donor organs will determine the quality of life for the recipient and the importance of optimal management of the multi-organ donor is that the organs may benefit up to five, critically ill, patients. The basic principle is to maintain sufficient preload to minimise the need for inotropic support and it is recommended that all multiple organ donors should have central venous and arterial pressure monitoring in addition to adequate venous access. The importance of the choice of fluid for volume expansion and the management of the hormonal disturbances which follow brain death are considered.

title: Comparison of electrical thresholds for evoking movements from sensori-motor areas of the cat cerebral cortex and its relation to motor training
abstract: Motor maps and electrical thresholds for evoking movements from motor areas of the cerebral cortex were evaluated in normal cats by using intracortical microstimulation techniques. Stainless steel chambers were implanted over craniotomies in adult cats trained to perform reaching and retrieval movements with their forelimbs. Prehensile motor training was continued and movement performance monitored for about 6–10 weeks during which the cortex was progressively explored with sharp tungsten electrodes inserted into cortical gyri (anterior and posterior sigmoid, and coronal) and the banks of sulci (cruciate, presylvian and coronal). Twice weekly, under light general anaesthesia, 3–4 tracks were made in either hemisphere till about 50 tracks were made in each hemisphere. Mean thresholds for evoking forelimb movements from different cytoarchitectonic areas (4γ, 4δ, 6aγ and 3a) were compared and no consistent or significant differences were observed between the different areas. In the animals (4/6) which used either forelimb to perform the tasks, there were no consistent differences in the mean thresholds for evoking forelimb movements from the two hemispheres. However, in 2 animals, which used their right forelimbs predominantly or exclusively to perform all the tasks, mean thresholds for evoking forelimb movements was significantly higher in areas 4γ and 6aγ of the left hemisphere (compared to the right); no consistent differences in the mean thresholds for evoking hindlimb or facial movements were observed between the two hemispheres. These findings suggest that ICMS thresholds for evoking forelimb movements may be similar in different sensorimotor areas of the cat cerebral cortex, and these thresholds could be influenced by motor training.

title: Report of a new syndrome: focus on differential diagnosis and review of Ellis-van Creveld, Curry-Hall, acrofacial dysostosis, and orofacial digital syndromes.
abstract: Ellis-van Creveld (EvC) and Curry-Hall (CH) syndromes are rare syndromes that occur due to mutations of genes mapped to the chromosome 4p16 region. Hence, they both have few features that are common. The dental literature describing the oral manifestations and etiology of both syndromes is scarce. We report a case of a 7-year-old girl who appeared with features that are common to both syndromes, as well as with other features such as reduced cranial base flexure and toes of equal length with skeletal changes that have not been mentioned or described in earlier reports. The patient possibly represents a new syndromic entity that has not been reported until now. Further, we present a review of various other similar syndromes, such as various types of orofacial digital (OFD) syndrome and acrofacial dysostosis.
