Objective: To analyze our institution’s work-up for patients with a diagnosis of subdural haematoma (SDH) in order to determine how many of them are secondary to child abuse, as well as to examine their final functional outcome. Methods: Retrospective review of children under 2 years of age diagnosed as having SDH between 1995 and 2005. Results: A total of 35 cases were identified. Fifteen patients that had underlying conditions that predispose them to bleed were excluded. Among the remaining 20 patients, seizures and head trauma were the main causes for consultation. All patients had a coagulation study and a head computed tomography carried out, 11 of these had a magnetic resonance imaging and 1 had a post-mortem examination. Bilateral SDHs in different stages of evolution was the most common pattern of intracranial haemorrhage. Fourteen infants had a skeletal survey, 4 had a bone scintigraphy and 19 had an ophthalmoscopic examination. Fractures were diagnosed in 7 patients and retinal haemorrhages in 11. The final diagnoses were: 10 shaken baby syndromes, 4 idiopathic SDH, 3 strokes, 2 coagulopathies and 1 accidental head injury. Upon follow-up, 1 patient had died and 9 had sustained permanent disabilities. Conclusions: Cases of infantile SDH are usually thoroughly investigated. In spite of this, sometimes it is not possible to determine the SDH aetiology. Nonetheless, shaken baby syndrome remains the most frequent cause of SDH in infants, and it carries a poor prognosis.

There are no unified protocols governing the management of healthy children with febrile neutropenia in the emergency department (ED). Conservative management is the norm, with admission and empirical broad-spectrum antibiotics prescribed, although viral infections are considered the most frequent etiology. The aim of this study was to describe the clinical outcomes and identified etiologies of unsuspected neutropenia in febrile immunocompetent children assessed in the ED. This was a retrospective study: well-appearing healthy children <18 years old with febrile moderate [absolute neutrophil count (ANC) 500-999 neutrophils ×10(9)/l] or severe (ANC <500 neutrophils ×10(9)/l) neutropenia diagnosed in ED between 2005 and 2013 were included. Patients newly diagnosed with hematologic or oncologic disease were excluded. We included 190 patients: 158 (83.2 %) with moderate and 32(16.8 %) with severe neutropenia. One hundred and one (53.2 %) were admitted; 48(47.5 %) with broad-spectrum antibiotics. The median length of stay was 3 days (IQR 3-5) and the median duration of neutropenia was 6 days (IQR 3-12). An infectious agent was identified in 23(12.1 %); 21 (91.3 %) were viruses. Four (2.1 %) children had a serious bacterial infection (SBI): urinary tract infection and lobar pneumonia (two cases each). All blood cultures performed (144; 75.8 %) were negative. Over the 1-year follow-up, one or several blood tests were performed on 167 patients (87.9 %); two (1.2 %) were diagnosed with autoimmune chronic neutropenia. Previously healthy children with moderate or severe febrile neutropenia have a low risk of SBI and a favorable clinical outcome. Less aggressive management could be carried out in most of them. Although chronic hematological diseases are infrequently diagnosed, serial ANC are necessary to detect them.

BCs are not useful in the management of immunocompetent patients admitted to the hospital with uncomplicated SSTIs. The prevalence of CA-MRSA is low in our area, but continuing careful surveillance is needed.

Afebrile young infants with UTI should not be classified a priori as low risk for bacteremia. Well-appearing young infants with UTI and procalcitonin value <0.7 ng/mL were at very low risk for bacteremia; outpatient management with an appropriate follow-up could be considered.
