Clinical implications of a possible role of vitamin D in multiple sclerosis

Hypovitaminosis D is currently one of the most studied environmental risk factors for multiple sclerosis (MS) and is potentially the most promising in terms of new clinical implications. These practical consequences, which could be applied to MS patients without further delay, constitute the main purpose of this review. Vitamin D is involved in a number of important general actions, which were not even suspected until quite recently. In particular, this vitamin could play an immunomodulatory role in the central nervous system. Many and varied arguments support a significant role for vitamin D in MS. In animal studies, vitamin D prevents and improves experimental autoimmune encephalomyelitis. Epidemiologically, latitude, past exposure to sun and the serum level of vitamin D influence the risk of MS, with, furthermore, significant links existing between these different factors. Clinically, most MS patients have low serum levels of vitamin D and are in a state of insufficiency or even deficiency compared to the international norm, which has been established on a metabolic basis. Large therapeutic trials using vitamin D are still lacking but the first results of phase I/II studies are promising. In the meantime, while awaiting the results of future therapeutic trials, it can no longer be ignored that many MS patients have a lack of vitamin D, which could be detected by a serum titration and corrected using an appropriate vitamin D supplementation in order to restore their serum level to within the normal range. From a purely medical point of view, vitamin D supplementation appears in this light to be unavoidable in order to improve the general state of these patients. Furthermore, it cannot currently be ruled out that this supplementation could also be neurologically beneficial

Addition of compounds of alkoxy antimony(V) tetrachlorides with some phosphoryl and amine-oxide ligands

An adduct of Tin(IV) trichloride (2-chloroethoxide) (A') with 2-chloroethylalcohol(A) has been prepared. Complexes of A' with amide, dimethylurea, dimethylsulphoxide, primary, secondary and tertiary amines and αα'-dipyridyl have been prepared. I.R. spectra of the complexes in 4000-250 cm<SUP>−1</SUP> spectral region have been examined to throw some light on their structure

A Twist on Lyme: the Challenge of Diagnosing European Lyme Neuroborreliosis▿

Lyme neuroborreliosis is a tick-borne illness with central and peripheral nervous system manifestations. Clinical features and methods for accurate diagnosis differ across world regions owing to different causative Borrelia species. The importance of these distinctions is highlighted by a 12-year-old Canadian girl who acquired Lyme neuroborreliosis in Europe

2018 in review: five hot topics in tropical medicine

Abstract The year 2018 heralded many new developments in the field of tropical medicine, including licensure of novel drugs for novel indications, licensure of existing drugs for existing indications but in novel settings, and globalized outbreaks of both vector-borne and zoonotic diseases. We herein describe five top stories in tropical medicine that occurred during 2018, and illuminate the practice-changing development within each story
