Comparison of topical tacrolimus 0.1 % in pectin ointment with clobetasol 0.5% ointment in adults with moderate to severe desquamative gingivitis: A …
2006
BACKGROUND: Desquamative gingivitis (DG) is a clinical condition characterized by red, painful, glazed, and friable gingiva, which might be a manifestation of some autoimmune mucocutaneous diseases. The time from the development of initial signs of DG to diagnosis can vary from months to years. Based on a literature search, no data concerning patients with DG without signs of autoimmune disease were available. OBJECTIVE: The aim of this trial was to compare the efficacy and tolerability of monotherapy with topical tacrolimus 0.1% in pectin ointment versus clobetasol propionate 0.5% ointment in adults affected by DG. METHODS: This randomized, double-blind clinical trial was conducted at the …
Amisulpride doses and plasma levels in different age groups of patients with schizophrenia or schizoaffective disorder.
2008
Abstract Because of a unique pharmacodynamic profile, amisulpride seems appropriate for treatment of elderly patients with schizophrenia. In a large-scale naturalistic therapeutic drug monitoring study, daily amisulpride dose, trough and dose-corrected amisulpride plasma levels, co-medication, clinical effectiveness (CGI) and side effects (UKU) were compared between age groups in 395 patients with schizophrenia or schizoaffective disorder (46% women; mean age 39.1 ± 14.2 years, range 18–83 years) under amisulpride therapy. Mean amisulpride doses (574 ± 269 mg/day), plasma levels (304 ± 274 ng/mL), dose-corrected amisulpride plasma levels (C/D ratios, 0.52 ± 0.41 ng/mL:mg), clinical respons…
Relaxation of the isolated human internal anal sphincter by sildenafil.
2007
Abstract Background Hypertonicity of the internal anal sphincter (IAS) appears to be involved in the pathogenesis of anal fissure. The relaxant effects of sildenafil, a selective phosphodiesterase 5 (PDE5) inhibitor, on isolated human IAS were investigated. Methods The efficacy (maximal effect, Emax) and potency (−log IC50, where IC50 is half-maximal inhibitory concentration) of the PDE5 inhibitors, sildenafil and zaprinast, and of nitric oxide donors, sodium nitroprusside and glyceryl trinitrate, as relaxants of histamine (0·1 mmol/l)-induced tone were examined in IAS strips under isometric contraction. The presence of PDE5 isoenzymes and changes in intracellular calcium and cyclic nucleot…
Prostaglandin E2 activates the ciliary beat frequency of cultured human nasal mucosa via the second messenger cyclic adenosine monophosphate.
2001
Prostaglandins influence the ciliary beat frequency (CBF) of ciliated nasal epithelial cells and a stimulatory effect has been described for prostaglandin E2 (PGE2). Until now, it is not known whether PGE2 has direct ciliostimulatory properties or acts through a second messenger. In this study we investigated whether cyclic adenosine monophosphate (cAMP) is implicated in the signal transduction pathway of PGE2-induced activation of CBF. Ciliated cells of the nasal mucosa were cultured for up to 5 days whereafter the culture medium was removed and the cells were incubated with different concentrations of test solutions. The ciliated cells were recorded under a phase-contrast microscope and v…
Comparative effects of dilator drugs on human penile dorsal artery and deep dorsal vein
1998
The present study was designed to characterize the response of human penile dorsal artery and deep dorsal vein to dilator drugs used in the diagnosis and treatment of erectile dysfunction with special emphasis on the effects on sympathetic neurotransmission. Ring segments of penile dorsal artery and deep dorsal vein were obtained from 20 multi-organ donors during procurement of organs for transplantation. The rings (3 ;mm long) were suspended in organ bath chambers for isometric recording of tension. We then studied the relaxant responses to prostaglandin E1 (PGE1), vasoactive intestinal peptide (VIP), papaverine (PV), sodium nitroprusside (SNP) and linsidomine chlorhydrate (SIN-1), and ana…
Clonidine induces nitric oxide- and prostaglandin-mediated vasodilation in healthy human skin
2005
Sustained sympathetic activation not only leads to vasoconstriction but also might induce paradox vasodilation. This study was performed to explore whether and how alpha(2)-receptor stimulation mediates this vasodilation. We investigated 11 healthy subjects in 33 dermal microdialysis (MD) sessions. After nerve trunk blockade, MD fibers were inserted and perfused with physiological saline until skin trauma-related vasodilation subsided. Thereafter, fibers were perfused with either clonidine solutions (10(-3), 5 x 10(-4), 10(-4) mol/l), N(G)-monomethyl-l-arginine (L-NMMA; nitric oxide synthase blocker), acetylsalicylic acid (ASA; cyclooxygenase blocker), or combinations of these. Laser-Dopple…
Inhibition of thromboxane biosynthesis by triflusal in type 2 diabetes mellitus.
2004
Abstract Triflusal is an antiplatelet drug related to aspirin, with different pharmacological properties and a lower haemorrhagic risk. We aimed at comparing their effects on platelet and endothelial activation in type 2 diabetes mellitus (T2DM). In a randomized, double-blind, parallel group study, we compared the effects of three daily regimens (300, 600, and 900mg) of triflusal, and aspirin (100mg/day) on urinary 11-dehydro-thromboxane (TX)B 2 , index of in vivo platelet activation, ex vivo platelet function using the analyzer PFA-100, plasma von Willebrand factor (vWF), P-selectin, intercellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), and serum nitrite a…
Consensus interferon and ribavirin for patients with chronic hepatitis C and failure of previous interferon-alpha therapy.
2006
BACKGROUND The efficacy of consensus interferon (CIFN), a synthetic IFN with optimised in vitro activity, was assessed in chronic hepatitis C virus (HCV) patients who had failed the pretreatment with interferon-alpha (IFNalpha) and ribavirin. METHODS One hundred and three patients after non-response (n=69) or relapse (n=34) to IFNalpha+/-ribavirin were randomly assigned to high-dose induction (CIFN 27-->9 microg daily for 24 weeks, 9 microg t.i.w. for 24 weeks) or low-dose treatment (CIFN 18 microg t.i.w. for 12 weeks, 9 microg t.i.w. for 36 weeks); each with ribavirin 800 mg/day. Follow-up was 24 weeks. RESULTS Non-responder patients treated with high-dose induction had higher early virolo…
Improved Responses to Pegylated Interferon Alfa-2b and Ribavirin by Individualizing Treatment for 24–72 Weeks
2011
Guidelines recommend that patients with chronic hepatitis C virus (HCV) infection be treated with pegylated interferon and ribavirin for 24, 48, or 72 weeks, based on their virologic response to treatment. We investigated the effects of treating patients for individualized durations.We treated 398 treatment-naïve patients who had HCV genotype 1 infections with pegylated interferon alfa-2b and ribavirin for 24, 30, 36, 42, 48, 60, or 72 weeks (mean of 39 weeks, termed individualized therapy); the duration of therapy was determined based on baseline viral load and the time point at which HCV RNA levels became undetectable (measured at weeks 4, 6, 8, 12, 24, and 30). Results were compared with…
Rapid Musculoskeletal Magnetic Resonance Imaging Using Integrated Parallel Acquisition Techniques (IPAT) - Initial Experiences
2003
Purpose To investigate the feasibility of using multiple receiver coil elements for time saving integrated parallel imaging techniques (iPAT) in traumatic musculoskeletal disorders. Material and methods 6 patients with traumatic derangements of the knee, ankle and hip underwent MR imaging at 1.5 T. For signal detection of the knee and ankle, we used a 6-channel body array coil that was placed around the joints, for hip imaging two 4-channel body array coils and two elements of the spine array coil were combined for signal detection. All patients were investigated with a standard imaging protocol that mainly consisted of different turbo spin-echo sequences (PD-, T (2)-weighted TSE with and w…
