ABSTRACT
Fluoroquinolones (FQs) are one of the most commonly prescribed classes of antibiotics. Although they were initially well tolerated in randomized clinical trials, subsequent epidemiological studies have reported an increased risk of threatening, severe, long-lasting, disabling and irreversible adverse effects (AEs), related to neurotoxicity and collagen degradation, such as tendonitis, Achilles tendon rupture, aortic aneurysm, and retinal detachment. This article reviews the main potentially threatening AEs, the alarms issued by regulatory agencies and therapeutic alternatives.

BACKGROUND: Immunity of healthcare workers (HCWs) against measles is a particular concern. They are more likely to contract it than the general population due to their occupational exposure which may cause a nosocomial outbreak. AIM: To assess the measles immune status of HCWs at five Spanish university hospitals. PATIENTS AND METHODS: Serologic testing (IgG) for measles by chemiluminescence indirect immunoassay (CLIA) was carried out prospectively and consecutively in HCWs from five university hospitals. All HCWs were classified into four epidemiological groups: vaccinated individuals, those with a history of measles disease, subjects with no history of measles or vaccination, and those who did not know whether they had measles or were vaccinated, and into five professional categories: physicians, nurses, nursing assistants, other clinical workers and non-clinical workers. A logistic regression model was constructed to identify the factors independently associated with immunity to measles. RESULTS: The study group was composed of 2157 HCWs. 89% had protective antibodies against measles. Of the 238 non-immune HCWs, 199 (83.6%) had been vaccinated, compared with 1084 of the 1919 (56.5%) immune individuals (P<0.0001). The parameters significantly predictive of having protective antibodies against measles were: older age (P<0.0001), epidemiological status (P=0.0002, mainly past measles disease), and professional category (P=0.02, in particular nurses). CONCLUSION: This study shows that HCWs, including those previously vaccinated, are currently at risk of measles and suggests that those with a natural history of infection are better protected. Therefore, knowledge and maintenance of immunity to measles are an essential part of infection control among HCWs.
ABSTRACT
Dalbavancin is a long-acting antimicrobial agent with an excellent in vitro activity against Gram-positive pathogens, including staphylococcal biofilms. The unusually long terminal half-life ranging from 149 to 250 hours in human subjects, allows a weekly dose. Currently is indicated in acute bacterial skin and skin structure infections (ABSSSIs), but in real-life clinical practice it has already been used successfully and safely in other infections, especially as consolidation therapy.

Oral antibiotics are among the most frequently used medications in the community. Its adverse effects are generally considered to be infrequent and mild, and include allergies, toxicities and drug interactions. Antibiotics are able to harm patients by various mechanisms, not always well known. Knowledge of the clinically relevant antibiotic-associated adverse effects can allow a judicious use based on the principle first do no harm, primun non nocere. In this review we explore the main adverse effects of oral antibiotics with specific focus on ß-lactams, macrolides, and fluoroquinolones.
