High doses of benzodiazepine predict analgesic and sedative drug withdrawal syndrome in paediatric intensive care patients.

AIM: Critically ill children can develop withdrawal syndrome after prolonged analgesia and sedation in a paediatric intensive care unit (PICU), when treatment is stopped abruptly or reduced quickly. The aim of this study was to evaluate the incidence of withdrawal syndrome in patients after three or more days of analgesic or sedative drug therapy, using a validated scale. We also analysed the association between withdrawal syndrome and the patients' outcome and factors related to analgesia and sedation treatment. METHODS: This prospective observational study analysed 89 periods of weaning from analgesia and sedation in 60 children between October 2010 and October 2011. Of these, 65% were less than six months old and 45% were admitted to the PICU after heart surgery. Withdrawal syndrome was assessed using the Withdrawal Assessment Tool-1 (WAT-1) scale. RESULTS: The incidence of withdrawal syndrome was 37%, and the only variable that predicted its presence was the highest administered dose of benzodiazepine. The duration of weaning, Sophia Observational Withdrawal Symptom scale score and nurse judgment were also associated with positive WAT-1 scores. CONCLUSION: Withdrawal syndrome should be considered after three or more days of analgesic or sedative treatment. A high dose of benzodiazepine increases the risk of developing withdrawal symptoms.

Practice of analgesia and sedation in Italian Paediatric Intensive Care Units: did we progress?

BACKGROUND: No strong recommendation was reported in management analgesia and sedation of critically ill children. The present study was performed to describe the current practice of analgesia and sedation in Pediatric Italian Intensive Care Units, in order to evaluate the adherence to last published pediatric guidelines. METHODS: A questionnaire was sent to 24 Italian Paediatric Intensive Care Units during 2010. RESULTS: One Hundred percent of contacted centers returned the filled form. All Pediatric Italian Intensive Care Units used the same combination (opioid plus benzodiazepine); 50% of centers referred to regularly monitor the level of sedation, but only 37% of them used validate tools. Withdrawal syndrome was regularly monitored in 25% of contacted Pediatric Italian Intensive Care Units; Finnegan scale was the only adopted scale. CONCLUSION: National pediatric intensivists identified the same drug strategy to obtain analgesia and sedation in their patients, according to last published guidelines. Assessment of analgesia and sedation was more diffuse but not regularly performed and different methods were used. Withdrawal syndrome was monitored in a minority of contacted centres. Considering our data the practice of analgesia and sedation in Italian Pediatric Intensive Care Units is improved but not yet completely adherent to last international recommendations.

[Linear IgA bullous dermatosis: the importance of a correct differential diagnosis]. / Dermatosi bollosa a IgA lineari: l'importanza di una corretta diagnosi differenziale.

Linear IgA bullous dermatosis is an acquired subepidermal blistering disease which belongs to bullous autoimmune diseases, along with dermatitis herpetiformis and bullous pemphigoid. Inflammatory blisters are the main clinical characteristics and the areas of common involvement are: perioral region, abdomen, perineum, buttocks and the interior side of thighs. Essential for the diagnosis is to find by direct immunofluorescence the presence of a linear band of IgA antibodies at the level of the basement membrane. We present the case of a 5 year-old Moroccan girl which arrived at our First Aid Department for bullous dermatitis, localized mainly on the abdomen, legs and thighs. During a short stay in Morocco, a month before, the little girl was stung by an insect and developed bullous dermatitis by a residual lesion. The child was in a good state of health but blood exams showed an increase of total IgE antibodies. The girl was admitted and during her hospitalisation we made a skin biopsy which led to a diagnosis of linear IgA dermatosis. She began a steroid therapy and there was a progressive regression of the lesions. At present, she does not take medicines anymore, she feels well and is submitted to ambulatory medical follow-up.
