Chronification of migraine: what clinical strategies to combat it?

2013

Once migraine becomes chronic and has transformed into a form of headache that occurs daily or almost, the treatment options available are few and complex. This makes it important to take action before this point is reached, using all the measures that can be obtained from our current knowledge of chronic migraine (or transformed migraine) on the one hand, and on the potential factors of chronification (or transformation) on the other. Therefore, in order to reduce the risk of migraine chronification, it would appear important to: (a) administer suitable preventive treatments for subjects who have been suffering from migraines ≥4 days a month for ≥3 months; (b) take special care not to over…

Viability and function of the cryopreserved whole rat ovary: comparison between slow-freezing and vitrification

2011

Objective To investigate four different protocols for cryopreservation of the whole rat ovary with intact vasculature to evaluate whether differences exist in post-thawing viability of the ovary after either vitrification or slow freezing. Design Experimental study. Setting Obstetrics and gynecology department. Animal(s) Immature Sprague-Dawley female rats. Intervention(s) Ovaries were isolated with the vascular tree intact up to the bifurcation of the abdominal aorta and were subsequently cannulated. The ovaries were flushed with increasing concentrations of the cryoprotectant dimethyl sulfoxide (DMSO) to either 1.5 or 7 M. The ovaries underwent cryopreservation by vitrification or passive…

Smokeless tobacco, sport and the heart

2014

SummarySmokeless tobacco (snuff) is a finely ground or shredded tobacco that is sniffed through the nose or placed between the cheek and gum. Chewing tobacco is used by putting a wad of tobacco inside the cheek. Smokeless tobacco is widely used by young athletes to enhance performance because nicotine improves some aspects of physiology. However, smokeless tobacco has harmful health effects, including cardiovascular disorders, linked to nicotine physiological effects, mainly through catecholamine release. Nicotine decreases heart rate variability and the ventricular fibrillation threshold, and promotes the occurrence of various arrhythmias; it also impairs endothelial-dependent vasodilation…

Changes in health sciences students' perception of obstetric violence after an educational intervention.

2020

Background\ud Obstetric violence is a type of gender-based violence that is presented structurally. This type of violence has physical and psychological consequences for both the women who experience it and health professionals. The World Health Organization adds that health professionals need training to ensure that pregnant women are treated with compassion and dignity.\ud \ud Objectives\ud The objective of the study was to evaluate health sciences students' perception of obstetric violence and to identify possible changes after an educational intervention.\ud \ud Design\ud A pre-post quasi-experimental study was carried out between January and June 2019.\ud \ud Settings and participants\…

Hypovitaminosis D and orthostatic hypotension: A systematic review and meta-analysis

2016

Objectives: Orthostatic hypotension is a common condition among older adults and is associated with a range of deleterious outcomes. Recently, interest has developed in hypovitaminosis D (defined as low 25 hydroxiyVitamin D levels) as a potential risk factor for orthostatic hypotension. We conducted a systematic review and meta-analysis examining the association of orthostatic hypotension between study participants with and without hypovitaminosis D, including the adjustment of potential confounders (age, sex, BMI, renal function, comorbidities, seasonality, use of antihypertensive medications, and supplementation with cholecalciferol). Methods: A systematic literature search of major elect…

Obstetric and offspring risks of women’s morbid conditions linked to prior anticancer treatments

2016

Background Literature shows the effects of type of cancer and/or anticancer treatment on live birth percentages and/or pregnancy and neonatal complications in female cancer survivors. However, studies analyzing the obstetric and offspring risks of the morbid conditions associated with previous anti-cancer treatments are missing. The present review aims to uncover these risks. Methods A literature search based on publications up to March 2016 identified by PubMed and references cited in relevant articles. Results The morbid conditions associated with prior anticancer treatments including chemotherapy, radiotherapy, surgery, and/or hematopoietic stem-cell transplant may induce not only obstet…

Towards a Rapid Screening of Liver Grafts at the Operating Room Using Mid-Infrared Spectroscopy

2020

The estimation of steatosis in a liver graft is mandatory prior to liver transplantation, as the risk of graft failure increases with the level of infiltrated fat. However, the assessment of liver steatosis before transplantation is typically based on a qualitative or semiquantitative characterization by visual inspection and palpation and histological analysis. Thus, there is an unmet need for transplantation surgeons to have access to a diagnostic tool enabling an in situ fast classification of grafts prior to extraction. In this study, we have assessed an attenuated total reflection-Fourier transform infrared (ATR-FTIR) spectroscopic method compatible with the requirements of an operatio…

Topical therapies for oral lichen planus management and their efficacy: a narrative review.

2012

Oral Lichen Planus (OLP) is a chronic inflammatory condition implicating T cell-mediated cytotoxicity, and involving oral mucosal surfaces. Several therapeutic regimens have been evaluated to treat OLP and pain related, but often without high level of evidence. Topical formulations are the favourite for the majority of cases; bioadhesive formulations have been considered very useful and practical for local drug delivery in oral mucosa, due to the increased residence time on the oral mucosa of the dosage forms and better therapeutic efficacy. In this narrative review, authors try to illustrate the current topical managements for OLP from the accessible literature on this topic. Steroids are …

Tetralogy of Fallot as a Model to Study Cardiac Progenitor Cell Migration and Differentiation During Heart Development

2009

Tetralogy of Fallot (ToF) has long been considered a congenital disorder that occurs due to environmental alterations during gestation. Recently, several mutated genes have been discovered that are thought to be responsible for the malformations observed in ToF. These genetic mutations, which are microdeletions, are sporadic and are frequently also present in trisomy 21 patients. The ToF malformations can be lethal, but for the last 50 years, surgical repairs that place an artificial patch to repair the four features of ToF have improved the survival of patients with ToF. However, 0.5% to 6% of patients who survive after surgical repair of ToF die of sudden cardiac death caused by ventricul…
