Antimicrobial prescriptions in neonatal intensive care units (NICUs) represent a point of concern for the emergence of MDROs and for morbidity associated with prolonged antibiotic exposure (e.g., invasive candidiasis, necrotizing enterocolitis, and late-onset sepsis). Antimicrobial stewardship programs (ASPs) have shown to be a valuable tool for the prevention of resistance with the goals of optimizing clinical outcomes while decreasing unnecessary prescribing. The most frequent ASP strategies include the correct collection and interpretation of microbiological specimens, prescription of the narrowest-spectrum antibiotic appropriate for a particular case, and de-escalation or discontinuation of therapy in defined situations...

Oral mucosal infections appear as localized or generalized lesions. Symptoms range from almost unnoticeable lesions to severe pain. Systemic disease, age, immunocompromised condition, and medication use are common causes. Local causes include dentures, poor oral hygiene, traumatized epithelium, ulcerations, dentures, implants, oral piercing, and reduced salivary secretion. Oral mucosal infections are underdiagnosed and microbiological diagnosis should be more frequently used. Candidiasis is most frequently diagnosed...

PTA is a collection of pus located between the tonsillar capsule and the pharyngeal constrictor muscle. It is considered a complication of acute tonsillitis and is the most prevalent deep neck infection (approximately 2000 cases annually in Denmark) and cause of acute admission to Danish ENT departments. Teenagers and young adults are most commonly affected and males may predominate over females. However, no studies of age- and gender-stratified incidence rates have previously been published. Furthermore, smoking may be associated with increased risk of peritonsillar abscess (PTA) development, although the magnitude of the association has not been estimated...

PURPOSE: Stem cell transplant (SCT) recipients commonly undergo bronchoalveolar lavage (BAL) collection as an infectious pulmonary work-up. Previous studies report the utility and overall diagnostic yield of fiberoptic bronchoscopy with BAL in this vulnerable population, though none focused purely on microbiologic yield or made comparisons with less invasive means of pathogen detection. We sought to determine and elaborate on the microbiologic yield of BAL in SCT recipients, assess a correlation between BAL studies and less invasive means of pathogen detection, and assess the utility of repeating a BAL within 30 days...
