RESUMO
Bronchiolitis, often caused by respiratory syncytial virus (RSV), is the commonest cause of hospitalisation in infancy. Serum transaminases are sometimes raised in children with bronchiolitis. We tested the hypothesis that raised transaminases are associated with increased disease severity in children ventilated for bronchiolitis. Prospective observational cohort study of mechanically ventilated children with community-acquired RSV bronchiolitis. Alanine transaminase (ALT) and aspartate transaminase (AST) levels were measured daily. Children with normal transaminases were compared with those with elevated levels. Over 11 consecutive winters, 556 children with RSV bronchiolitis were mechanically ventilated - 226 had comorbidities and therefore excluded; 313 of remaining 330 were under 2 years age; 305 had early transaminase measurements. 57/305 (19%) had elevated transaminase (AST and/or ALT) levels. For the first time we show that duration of ventilation and length of admission were both significantly longer, and paediatric index of mortality and C-reactive protein higher, in those with elevated AST levels on admission (but not those with elevated ALT levels). Furthermore, transaminase elevations were transient, generally having normalised by seven days following admission. RSV bronchiolitis was more severe in children with early elevated AST levels and could be used early in the illness as a predictor for disease severity.

Ethiopia has one of the world's poorest neonatal mortality rates (1). As a British paediatrician working for one year, the main aim was to improve neonatal care in a referral hospital's neonatal unit. An initial project looking at all admissions to the unit over the month of October 2012, revealed the death rate within the unit was 21% of all admissions. Of the 55 admissions only 43 (75%) had a temperature recorded at admission. 29 (67%) of these were hypothermic, and of these 29 initially hypothermic babies, 19 (65%) remained hypothermic or did not have another temperature documented during their stay. Only 33 (56%) had a heart rate and respiratory rate recorded on admission and only 11 (19%) had any further vital signs recorded during their stay. 19 of the admitted infants had a diagnosis of low birth weight and 10 (53%) of these either died or left against medical advice. With this information regular basic neonatal care teaching sessions for doctors and nursing staff were initiated. Vital signs charts were introduced and unit specific protocols were written. Continuous Positive Airway Pressure (CPAP) was trialled and found to be effective, and CPAP training was given to all nurses and doctors on the unit. A room was set aside to be used solely as Kangaroo Mother Care (KMC). The nurses were taken to a very effective neonatal unit as an 'experience sharing' trip to help with motivation and a grant was also obtained for basic equipment. After 6 months the project was repeated for all the admissions during February 2013. The death rate had progressively fallen and was 10% in February. 54 patients (98%) had a temperature taken on admission and of these, 27 (49%) were hypothermic. 25 (93%) of these hypothermic infants had subsequent temperatures documented which were normal. 54 (98%) had heart rate and respiratory rate recorded on admission and 50 (90%) had them recorded at least daily during their stay. Of the 22 babies with low birth weight (40%), only 4 (18%) died/left against medical advice. 4 received CPAP and 6 were treated with KMC.
