Risk factors associated with invasive pulmonary aspergillosis in severe COVID-19 patients: a casecontrol study.

Introduction: Since the onset of the COVID-19 pandemic, cases of COVID-19-associated pulmonary aspergillosis (CAPA) have been described. Possible risk factors for the development of this condition have been proposed, although evidence in Latin American populations is limited. The objectives were to identify risk factors for the development of CAPA and describe the characteristics of this infection.

[Reevaluation of penicillin allergy labeling, appropriate use of β-lactam antibiotics, and multidrug resistance].

Approximately 10% of the population reports being allergic to penicillin, although usually less than 1% really are. In addition, people with proven allergies over the years may no longer be allergic. Unconfirmed penicillin allergy and use of alternative antimicrobials result in more treatment failures; more severe adverse effects.

Toxic-Induced Encephalopathy Following Chemsex in a Young HIV-Positive Male: A Complex Case of Acute Cognitive Impairment with Anterograde Amnesia and Behavioral Alterations.

Background: A broadened clinical spectrum of concomitant complications emerges among the escalating incidence of substance use, particularly within the 'chemsex' context. This case exemplifies the profound neurotoxic repercussions and neurological risk of chemsex in a young HIV-positive male and addresses the multifaceted challenges of such evolving paradigms in substance utilization.

Clinical Finding: After consuming cannabis, poppers, methamphetamine, and cocaine, a 28-year-old HIV-positive male exhibited significant neurological and cognitive impairment.

[Colonic perforation and sepsis associated with Clostridium septicum as clinical presentation of colon cancer].
