Scorpion stings are a public health problem in many countries. However, in Colombia, very few epidemiological, clinical or toxicological studies have been undertaken. ⋯ The prevalence of stings by T. asthenes were common and their presence was associated with tropical rainforests. Envenomization at low density can be neutralized efficiently by anti-scorpion antivenoms produced in México and Brazil but with differing specificities for the venom of each scorpion species.

Review Case Reports
Empyema necessitans and acute osteomyelitis associated with community-acquired methicillin-resistant Staphylococcus aureus in an infant.
Staphylococcus aureus is a well recognized pathogen with global distribution. In recent years community-associated, methicillin-resistant S. aureus has emerged as an increasing cause of severe infections among adults and children. Herein, a case is reported of a previously healthy, 19-month-old male, who presented with empyema necessitans and acute osteomyelitis due to a community-associated, methicillin-resistant, S. aureus strain. This report highlights the evolving epidemiology of S. aureus, as important pathogen in the community as well as the hospital setting, and the importance of establishing appropriate guidelines for diagnosis, management and surveillance of this public health problem.

Fungal endocarditis is a cardiac complication that has been increasing throughout the world. We present a case of infective endocarditis by Paecilomyces variotii in a male patient with a prosthetic mitral valve. Successful treatment consisted of administration of amphotericin B (total dose 3670 mg) and mitral valve replacement. Only six cases have been reported previously, with a 100% mortality rate.

Pneumonia in patients with head trauma occurs commonly; however, few data are available to evaluate the effects of the infection on the prognosis. ⋯ The incidence of pneumonia in patients with severe brain trauma is high; however, its appearance does not affect the prognosis. The single significant risk factor was the presence of hypotension and vasopressor support.
