[Surgical site infections in children undergoing cardiac surgery with delayed sternal closure: Case-control study].
Surgical site infections (SSI) are an important cause of morbidity in pediatric cardiac surgery. Risk factors in patients requiring delayed sternal closure (DSC) are unknown. ⋯ The duration of BP and MV are risk factors of SSI in children undergoing cardiac surgery with DSC.

Comparative Study[Pneumocystis jiroveci infection in patients with and without HIV: A comparison].
Respiratory infection caused by Pneumocystis jiroveci is a common opportunistic infection in patients with human immunodeficiency virus (HIV) with CD4 counts < 200 cells/mm(3). However, it has also been reported in patients with other causes of immunosuppression. ⋯ Pneumocystis pneumonia mortality was higher in patients without HIV, who suffered more complications and progression to respiratory failure with MOF.

Case Reports[Pott's disease and immunological diagnosis of tuberculosis, about a pediatric clinical case].
Tuberculosis (TB) remains a major health problem in the world. The clinical forms of TB in children are variable, pulmonary involvement occurs in two thirds of cases. In the remaining third, clinical forms incluye node, meningeal and osteoarticular involvement. ⋯ 7 year old boy with a history of an osteolytic lesion of the right ischial branch. Three months later he presented with spondylodiscitis at L2-L3, associated with a large abscess in the right iliac psoas muscle. Pott's disease was suspected, and tuberculin test and T-SPOT®.TB test were performed, with a positive result. Antimicrobial treatment was initiated with isoniazid, rifampicin, pyrazinamide and ethambutol. After 30 days, Mycobacterium tuberculosis was isolated from psoas abscess. We discuss methods of TB diagnosis, with special emphasis on immunological methods: tuberculin test and interferon-gamma release assays. Methods of immunological TB diagnosis are an important contribution to the diagnosis of this disease, allowing early initiation of treatment.

Comparative Study[Pneumocystis jiroveci pneumonia: comparative study of cases in HIV-infected patients and immunocompromised non-HIV-infected patients].
Although P. jiroveci pneumonia affects immunocompromised (IC) patients of any etiology, clinical features and prognostic outcomes are different depending if they are patients with HIV infection or other causes of IC. ⋯ Our study confirmed that P. jiroveci pneumonia in non-HIV IC patients is more severe, more difficult to diagnose and has higher mortality that in HIV patients. Therefore, it is mandatory to optimize diagnostic and therapeutic strategies for this patients group.
