Mycotic infection prevalence among patients undergoing bronchoalveolar lavage with search of SARS-CoV-2 after two negative nasopharyngeal swabs.

The evidence that severe coronavirus disease 2019 (COVID-19) is a risk factor for development of mycotic respiratory infection with an increased mortality is rising. Immunosuppressed are among the most susceptible patients andspecies is the most feared superinfection. In this study we evaluated mycotic isolation prevalence on bronchoalveolar lavage (BAL) of patients who underwent bronchoscopy in search of severe acute respiratory coronavirus 2 (SARS-CoV-2) RNA.

[The descending necrotizing mediastinitis].

Descending necrotizing mediastinitis (DNM) is a primary complication of cervical or odontoiatric infections that can spread to the mediastinum through the anatomic cervical spaces. The delay of the diagnosis or under assessment of the disease, with no adequate draining techniques, results in high mortality up to 20%. We report our experience about 9 clinical cases of DNM observed and surgically treated in our unit from 2000 to 2006; five of these patients were admitted in the last two years.

Improvement of wound healing after hemorrhoidectomy: a double-blind, randomized study of botulinum toxin injection.

Purpose: Hemorrhoidectomy is usually associated with significant pain during the postoperative period. The spasm of the internal sphincter seems to play an important role in the origin of pain. This study was designed to evaluate the effectiveness of intrasphincter injection of botulinum toxin after hemorrhoidectomy in reducing the maximum resting pressure of the anal canal, accelerating wound healing, and decreasing postoperative pain when resting and during defecation.
