Clinical activity after fingolimod cessation: Disease reactivation or rebound?
2018
Background and purpose There is debate as to whether the apparent rebound after fingolimod discontinuation is related to the discontinuation itself or whether it is due to the natural course of highly active multiple sclerosis (MS). Our aim was to survey the prevalence of severe reactivation and rebound after discontinuation of fingolimod in a cohort of Italian patients with MS. Methods Patients with relapsing-remitting MS who were treated with fingolimod for at least 6 months and who stopped treatment for reasons that were unrelated to inefficacy were included in the analysis. Results A total of 100 patients who had discontinued fingolimod were included in the study. Fourteen patients (14%…
The bronchodilation response to deep inspiration in asthma is dependent on airway distensibility and air trapping
2011
In healthy individuals, deep inspirations (DIs) have a potent bronchodilatory ability against methacholine (MCh)-induced bronchoconstriction. This is variably attenuated in asthma. We hypothesized that inability to bronchodilate with DIs is related to reduced airway distensibility. We examined the relationship between DI-induced bronchodilation and airway distensibility in 15 asthmatic individuals with a wide range of baseline lung function [forced expired volume in 1 s (FEV1) = 60–99% predicted]. After abstaining from DIs for 20 min, subjects received a single-dose MCh challenge and then asked to perform DIs. The effectiveness of DIs was assessed by the ability of the subjects to improve …
The Effect of Age, Sex, Smoking and Co-Medication on Serum Levels of Venlafaxine and O-Desmethylvenlafaxine under Naturalistic Conditions
2012
Venlafaxine (VEN) is a modern antidepressant which exerts both serotonin and norepinephrine reuptake inhibition. In this study we examined the influence of age, sex, smoking, and co-medication on serum levels of VEN and its metabolite O-desmethylvenlafaxine (ODVEN) in patients treated with VEN under naturalistic conditions.We retrospectively evaluated 478 TDM analyses of VEN requested in the Pychiatric University Hospitals of Mainz, Regensburg, and Würzburg. The determination of serum levels was performed by virtually identical chromatographic methods in the TDM laboratories of the participating hospitals.Serum levels varied widely on each dose level. Women had about 30% higher dose-correct…
Influence of hemostatic agents upon the outcome of periapical surgery: dressings with anesthetic and vasoconstrictor or aluminum chloride
2011
Objective: To evaluate the effects of different hemostatic agents upon the outcome of periapical surgery. Design: A retrospective study was made of patients subjected to periapical surgery between 2006-2009 with the ultrasound technique and using MTA as retrograde filler material. We included patients with a minimum follow-up of 12 months, divided into two groups according to the hemostatic agent used: A) dressings impregnated in anesthetic solution with adrenalin; or B) aluminum chloride paste (Expasyl™). Radiological controls were made after 6 and 12 months, and on the last visit. The global evolution scale proposed by von Arx and Kurt (1999) was used to establish the outcome of periapica…
Simultaneous sodium lauryl sulphate testing improves the diagnostic validity of allergic patch tests. Results from a prospective multicentre study of…
2005
Summary Background There is evidence that a higher skin susceptibility may induce nonspecific erythematous or weak positive reactions to contact allergens in patch testing. Objectives To evaluate whether simultaneous application of sodium lauryl sulphate (SLS) along with diagnostic patch tests with contact allergens can provide information regarding skin irritability which may help to discriminate allergic from nonspecific irritant reactions to contact allergens. Methods Between July 2001 and June 2003, this prospective study collected patch test data of 5971 patients from 19 centres in Germany and Austria in the Information Network of Departments of Dermatology (IVDK). In addition to co…
Treatment nonadherence and neurocognitive impairment in bipolar disorder.
2009
OBJECTIVE: Little is known regarding the relationship between treatment adherence and residual cognitive dysfunction in euthymic bipolar disorder patients. This study aimed to investigate whether poor treatment adherence is associated with cognitive impairment in euthymic bipolar patients and whether other factors may be associated with both adherence and cognitive functioning. METHOD: Euthymic DSM-IV bipolar I or II disorder patients (N = 103: 61 with high levels of treatment adherence and 42 with poor treatment adherence) were assessed using a neuropsychological battery targeting attention, psychomotor speed, verbal memory, and executive functions and compared with 35 healthy controls of …
Improvement of wound healing after hemorrhoidectomy: a double-blind, randomized study of botulinum toxin injection.
2005
PURPOSE: Hemorrhoidectomy is usually associated with significant pain during the postoperative period. The spasm of the internal sphincter seems to play in important role in the origin of pain. This study was designed to evaluate the effectiveness of intrasphincter injection of botulinum toxin after hemaorrhoidectomy in reducing the maximum testing pressure of the anal canal, accelerating wound healing, and decreasing postoperative pain when resting and during defecation. METHODS: Thirty patients with hemorrhoids of third and fourth degree were included in the study and randomized in two groups. Anorectal manometry was performed preoperatively and 5 and 30 days afterward ill all patients un…
CYP2D6 polymorphism and clinical effect of the antidepressant venlafaxine.
2006
SUMMARY Background: Venlafaxine (V) is a mixed serotoninand noradrenaline reuptake inhibitor used as afirst-line treatment of depressive disorders. It ismetabolized primarily by the highly polymorphiccytochrome P450 (CYP) enzyme CYP2D6 to yielda pharmacologically active metabolite, O-des-methylvenlafaxine (ODV), and to a lesser extentby CYP3A4, to yield N-desmethylvenlafaxine(NDV).Objectives: The aim of this study was to assesswhether the O-demethylation phenotype of V hasan impact on the pharmacokinetics and clinicaloutcome.Method: In 100 patients treated with V, serumconcentrations of V, ODV and NDV and theratios of concentrations ODV/V as a measure ofO-demethylation were determined. Indiv…
Non-classic cystic fibrosis associated with D1152HCFTR mutation

Burgel P-R, Fajac I, Hubert D, Grenet D, Stremler N, Roussey M, Siret D, Languepin J, Mely L, Fanton A, Labbe A, Domblides P, Vic P, Dagorne M, Reynaud-Gaubert M, Counil F, Varaigne F, Bienvenu T, Bellis G, Dusser D. Non-classic cystic fibrosis associated with D1152H CFTR mutation. Background: Limited knowledge exists on phenotypes associated with the D1152H cystic fibrosis transmembrane conductance regulator (CFTR) mutation. Methods: Subjects with a D1152H allele in trans with another CFTR mutation were identified using the French Cystic Fibrosis Registry. Phenotypic characteristics were compared with those of pancreatic insufficient (PI) and pancreatic sufficient (PS) cystic fibrosis (CF)…
Hemostatic Agents in Periapical Surgery: A Randomized Study of Gauze Impregnated in Epinephrine versus Aluminum Chloride
2016
Abstract Introduction Adequate bleeding control is essential for the success of periapical surgery. The aim of this study was to evaluate the effects of 2 hemostatic agents on the outcome of periapical surgery and their relationship with patient and teeth parameters. Methods A prospective study was designed with 2 randomized parallel groups, depending on the hemostatic agent used: gauze impregnated in epinephrine (epinephrine group) and aluminum chloride (aluminum chloride group). The analysis of the hemorrhage control was judged before and after the application of the hemostatic agents by the surgeon, and 2 examiners independently recorded it as adequate (complete hemorrhage control) or in…
