Pneumomediastinum and subcutaneous emphysema after noninvasive ventilation in a COVID-19 patient.

Pneumomediastinum is an uncommon but well recognized complication of both invasive and non-invasive mechanical ventilation. Spontaneous pneumomediastinum has been observed in association with a variety of structural lung diseases including severe interstitial disorders. More recently it has been reported complicating the course of COVID-19 pneumonia.

Procalcitonin and secondary bacterial infections in COVID-19: association with disease severity and outcomes.

Introduction: Procalcitonin (PCT) is an emerging prognostic marker in coronavirus disease 2019 (COVID-19). Whether PCT can detect secondary bacterial infections or reflect target tissue injury in this setting is still unclear. Here we performed a meta-analysis to review the prognostic value of PCT for severe disease and adverse outcome events in COVID-19.

Hospitalisation and morbidity due to adverse drug reactions in elderly patients: a single-centre study.

Background: Adverse drug reaction (ADR) is a leading but under-recognised cause of illness, particularly in frail subjects with multiple comorbidities.

Aim: To investigate the frequency, patterns and outcomes of ADR as a cause of hospitalisation in elderly patients admitted to an internal medicine ward.

Methods: We performed a retrospective observational study including every patient aged over 65 years who was admitted to our department during a 12-month period.

Rectus abdominis muscle endometriosis: case report and review of the literature.

The abdominal wall is an uncommon site of extrapelvic endometriosis, which usually develops in a previous surgical scar and it should be considered in the differential diagnosis of any abdominal swelling. Endometriosis involving the rectus abdominis muscle is a very rare event and its rarity explains the incomplete nature of the reports in the literature. Up to the present, 18 cases with lesions contained entirely within the rectus abdominis muscle were clearly documented in medical literature with only four cases as a primary location.

Multiresistant-MRSA tricuspid valve infective endocarditis with ancient osteomyelitis locus.

Background: Methicillin-resistant S. aureus (MRSA) with low susceptibility to glycopeptides is uncommon.

Case Presentation: The case of a 50-year-old non-drug addict patient presenting with tricuspid valve infective endocarditis (IE) by MRSA resistant to vancomycin and linezolid is presented.
