Topical azithromycin for the prevention of Lyme borreliosis: a randomised, placebo-controlled, phase 3 efficacy trial

2017

Summary Background Lyme borreliosis develops in 1–5% of individuals bitten by ticks, but with a diagnostic gap affecting up to 30% of patients, a broadly applicable pharmacological prevention strategy is needed. Topical azithromycin effectively eradicated Borrelia burgdorferi sensu lato from the skin in preclinical studies. We assessed its efficacy in human beings. Methods In this randomised, double-blind, placebo-controlled, multicentre trial done in 28 study sites in Germany and Austria, adults were equally assigned to receive topical 10% azithromycin or placebo twice daily for 3 consecutive days, within 72 h of a tick bite being confirmed. Randomisation numbers, which were stratified by …

Is telephone follow-up really effective in early diagnosis of inflammatory complications after tooth extraction?

2018

Background To establish whether telephone follow-up is really able to intercept post-extraction complications and to evaluate the degree of patient satisfaction with this kind of post-surgical monitoring. Material and Methods Six hundred and thirty-eight patients were enrolled and randomly assigned to a test or control group. Test group patients were monitored by telephone follow-up 24 and 72 hours after surgery to investigate the presence of local symptoms that are frequently associated with surgical wound infection and inflammation. Both test and control group patients were examined 7 days at suture removal. Patients with systemic diseases, those in which intra-operative accidents occurre…

Dose-dependent absorption and elimination of cefadroxil in man.

1991

The pharmacokinetic behaviour of cefadroxil was dose-dependent in healthy male volunteers following the oral administration of single doses of 5, 15, and 30 mg.kg-1. As the dose of cefadroxil increased from 5 to 15 and 30 mg.kg-1, the peak plasma concentrations, normalized to 5 mg.kg-1, decreased significantly from 15.1 to 10.7 and 7.6 mg.l-1, while the corresponding normalized areas under the plasma concentration-time curves from 0 to 2 h decreased significantly from 1258 to 946 and 801 min.mg.l-1. When the same subjects were given 5 mg.kg-1 of cefadroxil together with 45 mg.kg-1 of cephalexin, the absorption of cefadroxil was slowed to a similar or greater extent than with the high dose o…

Escalating doses of paclitaxel and epirubicin in combination with cisplatin in advanced ovarian epithelial carcinoma: a phase I–II study

2003

Our objective was to identify a new active three-drug combination regimen consisting of paclitaxel (PTX), epirubicin (EPI) and cisplatin as first-line line chemotherapy for advanced ovarian carcinoma. A phase I study was carried out to evaluate the dose-limiting toxicity (DLT) and the maximally tolerated dose (MTD) of PXT and EPI in combination with a fixed dose of cisplatin every 4 weeks. Side-effects were recorded according to the NCI Common Toxicity Criteria. Patients were treated in cohorts of three with fixed-dose cisplatin 80 mg/m 2 and EPI 80 → 100 mg/ m 2 and PXT 100 → 160 mg/m 2 until DLT was reached. Once MTD was identified, a single-step phase II study was therefore carried out t…

Multicenter phase II study of oral idarubicin in treated and untreated patients with B-chronic lymphocytic leukemia.

2000

Idarubicin is the first anthracycline that can be administered orally facilitating antineoplastic chemotherapy at an improved quality of life. In different studies idarubicin has proved clinical effectiveness in patients with advanced low grade non Hodgkin's lymphoma. We performed a phase II study in 19 patients with untreated and pretreated B-CLL of Binet stage A-C. Idarubucin was administered orally at a dose of 15 mg/m2 over 3 days every 4 weeks. Of 19 evaluable patients (m:f, 16:3, median age 64 years, range 41-80 years) 7 were previously untreated while 12 patients had received prior therapy with fludarabine, chlorambucil or similar non-anthracycline containing regimens. 12 pts had Bin…

Re: Antimicrobial Resistance in More Than 100,000 Escherichia coli Isolates According to Culture Site and Patient Age, Gender, and Location

2011

ABSTRACT Escherichia coli and the antimicrobial pressure exerted on this microorganism can be modulated by factors dependent on the host. In this paper, we describe the distribution of antimicrobial resistance to amikacin, tobramycin, ampicillin, amoxicillin clavulanate, cefuroxime, cefoxitin, cefotaxime, imipenem, ciprofloxacin, fosfomycin, nitrofurantoin, and trimetoprim-sulfametoxazole in more than 100,000 E. coli isolates according to culture site and patient age, gender, and location. Bayesian inference was planned in all statistical analysis, and Markov chain Monte Carlo simulation was employed to estimate the model parameters. Our findings show the existence of a marked difference in…

Prevalence of surgical site infections before and after the implementation of a multimodal infection control programme

2012

Objectives: In order to assess the prevalence of surgical site infections (SSIs) before and after the implementation of a multimodal infection control programme including the realization of a campaign to increase compliance with guidelines for antimicrobial prophylaxis, we designed and conducted the present study involving all 20 of the surgical departments of a large teaching hospital in Catania, Italy. Patients and methods: SSI definitions of the Hospital in Europe Link for Infection Control through Surveillance (HELICS) protocol were used in four 1 day point-prevalence surveys. After the first survey, an infection control programme was implemented involving the active commitment of surge…

Topical Antibiotic, Antifungal, and Antiseptic Solutions Decrease Ciliary Activity in Nasal Respiratory Cells

2002

This study was designed to investigate whether topical solutions, as they are used in the treatment of selected cases of rhinosinusitis, influence nasal mucociliary clearance. The objective of this study was to evaluate the effects of the following topical solutions on the ciliary beat frequency (CBF) of nasal respiratory cells: ofloxacin as an antibiotic; Betadine and hydrogen peroxide (H2O2) as antiseptic; and amphotericin B, itraconazole, and clotrimazole as antifungal solutions. Differences are described between effects of each of these substances and we clarify whether ciliotoxic effects are dose dependent and if they can be reduced or eliminated by diluting the concentration of the a…

Knowledge and attitudes towards the use of antibiotics in the paediatric age group: a multicenter survey in Italy

2017

Background : The misuse of antibiotics is one of the leading causes of antibiotic resistance. Paediatric patients are highly involved in this issue, as they are those who receive the largest amount of prescriptions of these drugs. Therefore, this study aimed to investigate the general knowledge regarding the use of antibiotics, as well as the attitudes related to the administration of these drugs to children, amongst parents of children in the paediatric age-group. Methods : In 2014, a multicentre cross-sectional study was conducted amongst parents of children aged 0–14. A questionnaire made up of 33 items was administered in waiting rooms of outpatient departments. Multivariable logistic r…
