Contamination in Urine Samples Collected Using Bladder Stimulation and Clean Catch Versus Urinary Catheterization in Infants Younger Than 90 Days.

Objectives: The objective of this study was to compare the risk of contamination for urine samples collected from patients younger than 90 days using 2 different techniques: bladder stimulation and "clean catch" (CC) and urinary catheterization (CATH).

Methods: A case-control study was carried out in the pediatric emergency room of a tertiary hospital between January 2016 and September 2017. All urine samples collected from patients younger than 90 days by CC or CATH were included.

Endoscopic balloon dilation in duodenal stenosis secondary to intestinal lymphoma in a heart transplant patient.

Intestinal lymphoma can appear as a result of a state of immunosuppression, secondary to the transplantation of solid organs. Treatment with chemotherapy can result in various complications such as intestinal stenosis due to fibrotic scar tissue, which is a complication barely described in the literature. We present the case of a 12-year-old male with a heart transplant, who was diagnosed with intestinal lymphoma.

[Treatment with high-flow oxygen therapy in asthma exacerbations in a paediatric hospital ward: Experience from 2012 to 2016].

Objective: To assess the experience with oxygen therapy with a high flow nasal cannula (HFNC) in hospital on patients with asthmatic exacerbation (AE) in a paediatric ward, and to assess the clinical outcome according with the initial oxygen flow (15lpm or <15lpm).

Methods: This was a retrospective study of children aged 4 to 15 years with AE admitted to a paediatric ward in a tertiary level hospital between 2012 and 2016. Two groups of patients were compared; Group 1: patients treated with HFNC, and Group 2: patients treated with conventional oxygen therapy.

[Mammary hemangioma in an infant with apparent mastitis. Case report].

Mammary pathology is infrequent during childhood. It is rare the probability of finding a breast mass in an infant. The most frequent possible diagnoses at this age are breast abscess, mastitis, breast engorgement due to maternal hormonal stimulation and hemangioma.

Downbeat nystagmus due to ranitidine in a pediatric patient.

Background: Ranitidine has not been considered as a potential cause of ocular movement conditions. However, it is known that the vestibular nucleus complex, that has a key role in gaze control and vestibule-ocular reflexes, receives hypothalamic histaminergic innervations. Some studies reported the effect of ranitidine blocking the excitatory responses of vestibular nuclei neurons to histamine.
