Economic burden of skin and skin structure infections due to Gram-positive bacteria in patients on hospital at home-based outpatient parenteral antibiotic therapy (OPAT).

Objective: To describe and quantify resource use and direct health costs associated with skin and skin structure infections (SSSIs) caused by Gram-positive bacteria in adults receiving outpatient parenteral antimicrobial therapy (OPAT), administered by Hospital at Home units (HaH) in Spain.

Methods: Observational, multicenter, retrospective study. We included patients of both sexes included in the HaH-based OPAT Registry during 2011 to 2017 who were hospitalized due to SSSIs caused by Gram-positive bacteria.

An unusual presentation of secondary pleural hydatidosis.

Although pleural involvement is relatively common in cystic hydatid disease, one of the rarest and least known complications is secondary pleural hydatidosis. We report the case of a patient who presented with polycystic secondary pleural hydatidosis 4 yrs after treatment for a pyopneumothorax caused by rupture of a pulmonary cyst near the pleural space. Due to the coexistence of severe chronic obstructive pulmonary disease, surgery was ruled out.

[Mediastinal non-Hodgkin's lymphoma: atypical presentation diagnosed with bronchoscopy].

Primary mediastinal non-Hodgkin lymphoma is a rare entity that can manifests with secondary pulmonary involvement. The case of a 37 years-old man patient with non-Hodgkin lymphoma mixed B-cell, which was diagnosed by means of bronchoscopic biopsy, is presented. His characteristics clinical and radiologic presentation, and diagnostic usefulness of fiberoptic bronchoscopy, is remarked.

A 24-year-old woman with an unremarkable history presented with a large right-sided pleural effusion. Analysis of the pleural fluid showed a sterile exudate with a low sugar level. Complementary analyses were unable to pinpoint the etiology.

[Efficacy and tolerance of the treatment of tuberculosis in the aged].
