Direct costs of low respiratory infection due to RSV in children under one year.

Introduction: Considering the high prevalence of respiratory infections in hospitalized infants with Respiratory Syncytial Virus (RSV), the objective of this study is to determine the direct costs of this infection.

Patients And Method: Prospective longitudinal study in infants under one year of age hospitalized due to RSV during 2015. The patients were divided into 2 groups, Group 1 pa tients without risk factors and Group 2 patients with risk factors (prematurity, oxygen dependence, bronchopulmonary dysplasia, heart disease, immunocompromised patients), comparing each other variables such as nutritional status, gender, breastfeeding, discharge diagnosis, radiological diagno sis, length of hospital stay, among others.

[Bartonella henselae vertebral osteomyelitis: report of a case].

Unlabelled: Cat scratch disease (CSD) is caused by Bartonella henselae, with unknown prevalence and incidence in the Chilean paediatric population. Regional lymphadenopathy is the most common presentation, while atypical forms constitute a diagnostic challenge.

Objective: To report a case of CSD with osteomyelitis and present guidelines regarding treatment.

[Caudal regression sequence: clinical-radiological case].

Caudal regression syndrome is an uncommon congenital malformation that includes a wide spectrum of clinical presentations. Characterised by caudal musculoskeletal compromise, it can be associated to neurological, gastrointestinal, renal and genitourinary defects. Although the specific aetiology has not been clarified, it has been associated with the presence of maternal diabetes and mutations in homeobox gene HBLX9.
