Opioid Plasma Concentrations during a Switch from Transdermal Fentanyl to Methadone

2007

Opioid switching is often used to improve the opioid response in patients with cancer experiencing poor analgesia or adverse effects. When switching between drugs with delayed effect because of pharmacokinetics or type of delivery, concerns exist about the correct timing of introducing the second drug after stopping the previous one. The aim of this study was to assess plasmatic changes of fentanyl and methadone underlying the clinical events occurring during opioid switching. Eighteen patients with cancer receiving transdermal fentanyl with uncontrolled pain and/or moderate to severe opioid adverse effects, were switched to oral methadone using an initial fixed ratio of 1:20. Fentanyl patc…

Continuous therapy with transdermal nitroglycerin does not affect biomarkers of vascular inflammation and injury in healthy volunteers.

2009

Continuous exposure to nitroglycerin (GTN) results in development of tolerance and is associated with increased free radical production and abnormal endothelial function. Elevated plasma biomarkers of inflammation have been shown to be associated with endothelial dysfunction in most cardiovascular conditions. It remains unclear whether exposure to GTN is also associated with increased biomarkers of endothelial and vascular injury or vascular inflammation. In an investigator-blind study, a total of 28 healthy volunteers were randomized to continuous therapy with GTN (0.6 mg/h 24 h/day for 7 days) or no therapy. Venous blood was collected on day 0 and day 7. Plasma levels of markers such as …

Antral Follicle Priming Before Intracytoplasmic Sperm Injection in Previously Diagnosed Low Responders: A Randomized Controlled Trial (FOLLPRIM).

2015

A low response to controlled ovarian hyperstimulation implies a reduced number of embryos and impaired pregnancy rate. Follicular priming with steroids before controlled ovarian hyperstimulation has been suggested to improve the subsequent ovarian response.The purpose of this study was to determine the best follicular priming protocol in low responders and to investigate the intrafollicular mechanisms triggered by steroid hormone priming.This was a single-center, randomized, parallel, open-label, controlled trial, in two phases.The setting was a university-based in vitro fertilization unit.Potential low responders (n = 99) underwent a first intracytoplasmic sperm injection cycle. Confirmed …

Vascular patterns in cutaneous leishmaniasis: A videodermatoscopic study

Clinical features and epidemiology of cutaneous leishmaniasis and Leishmania major/HIV co-infection in Cameroon: results of a large cross-sectional s…

2011

Cutaneous leishmaniasis (CL) is endemic in Central Africa, including Cameroon. However, data on its prevalence and co-infection with HIV are scarce. Here we present the results of a large cross-sectional study reporting the prevalence, clinical features and species identification of CL and HIV co-infection in northern Cameroon. A total of 32 466 subjects were clinically screened for CL during a door-to-door survey, followed by parasitological diagnosis in the field laboratory. Amongst the subjects surveyed, 146 (0.4%) were diagnosed with active CL. Seven (4.8%) of these 146 CL patients tested positive for HIV-1 and/or HIV-2. The number of lesions per CL patient ranged from 1 to 20. Three of…

No change in apolipoprotein AI metabolism when subcutaneous insulin infusion is replaced by intraperitoneal insulin infusion in type 1 diabetic patie…

2006

In type 1 diabetic patients, the replacement of subcutaneous insulin infusion by intraperitoneal insulin infusion restores the normal physiological gradient between the portal vein and the peripheral circulation, which is likely to modify HDL metabolism. This stable isotope kinetic study was designed to compare HDL apolipoprotein (apo) AI metabolism in seven type 1 diabetic patients first treated by continuous subcutaneous insulin infusion by an external pump and then 3 months after the beginning of intraperitoneal insulin infusion by an implantable pump. Glycaemic control was comparable under subcutaneous and intraperitoneal insulin infusion (HbA1c=7.34+/-0.94% versus 7.24+/-1.00%, NS). HD…

Tolerance to nitroglycerin-induced preconditioning of the endothelium: a human in vivo study

2009

Damage and dysfunction of the vascular endothelium critically influence clinical outcomes after ischemia and reperfusion (I/R). Brief exposure to organic nitrates can protect the vascular endothelium from I/R injury via a mechanism that is similar to ischemic preconditioning and is independent of hemodynamic changes. The clinical relevance of these protective effects clearly depends on whether they can be sustained over time. Twenty-four healthy (age 25–32) male volunteers were randomized to receive 1) transdermal nitroglycerin (GTN; 0.6 mg/h) administered for 2 h on 1 day only, 2) transdermal GTN for 2 h/day for 7 days, or 3) continuous therapy with transdermal GTN for 7 days. Eight volunt…

Cutaneous lupus erythematosus: First multicenter database analysis of 1002 patients from the European Society of Cutaneous Lupus Erythematosus (EUSCL…

2012

In this prospective, cross-sectional, multicenter study, we assessed clinical and laboratory characteristics from patients with cutaneous lupus erythematosus (CLE) using the Core Set Questionnaire of the European Society of Cutaneous Lupus Erythematosus (EUSCLE). 1002 (768 females, 234 males) patients with different subtypes of CLE, such as acute CLE (ACLE, 304 patients), subacute CLE (SCLE, 236 patients), chronic CLE (CCLE, 397 patients), and intermittent CLE (ICLE, 65 patients), from 13 European countries were collected and statistically analyzed by an SPSS database. The main outcome measures included gender, age at onset of disease, LE-specific and LE-nonspecific skin lesions, photosensi…

Efficacy, safety and quality of life of calcipotriol/betamethasone dipropionate (Dovobet (R)) versus calcipotriol (Daivonex (R)) in the treatment of …

2007

Objective: A clinical trial was performed to evaluate the efficacy, speed of response, side effects and quality of life of patients treated with calcipotriol/betamethasone dipropionate (Dovobet (R)) for 4 weeks followed by maintenance with calcipotriol for 8 weeks (group A) versus calcipotriol (Daivonex (R)) alone for 12 weeks (group B) for the treatment of psoriasis. Materials and methods: A total of 150 patients were enrolled and randomized to groups A and B. PASI and Skindex-29 were considered the outcome measures. Results: Ninety-six patients completed the trial. At weeks 2 and 4, both groups showed a significant clinical improvement compared to baseline; group A demonstrated a higher c…

Photochemotherapy Alone or Combined with Interferon Alpha-2a in the Treatment of Cutaneous T-Cell Lymphoma

1990

Eighty-two patients with either mycosis fungoides (MF) or parapsoriasis en plaques were treated with psoralens ultraviolet A light (PUVA). Clinical and histologic parameters were followed for a period from 6 months to 10 years. Complete clinical clearing of lesions was observed in 51 patients (62%) and most of them were in limited-plaque MF group or parapsoriasis en plaque. The mean total dose of PUVA for complete clearing was less for early MF. Thirty-one patients (38%) relapsed and responded to additional PUVA. Patients in early stages of the disease remained clear for up to 68 months after the first course of PUVA. Post-treatment skin biopsies with early MF showed histologic clearing. A …
