Cooking influence in tolerance acquisition in egg-induced acute food protein enterocolitis syndrome.

BACKGROUND: Few studies on the age of resolution of Food Protein Induced Enterocolitis Syndrome (FPIES) induced by solid foods are available. In particular, for FPIES induced by egg, the mean age of tolerance acquisition reported in the literature ranges from 42 to 63 months. OBJECTIVE: We have assessed whether the age of tolerance acquisition in acute egg FPIES varies depending on whether the egg is cooked or raw. METHODS: We conducted a retrospective and multicentric study of children with diagnosis of acute egg FPIES seen in 10 Italian allergy units between July 2003 and October 2017. The collected data regarded sex, presence of other allergic diseases, age of onset of symptoms, kind and severity of symptoms, cooking technique of the ingested egg, outcome of the allergy test, age of tolerance acquisition. RESULTS: Sixty-one children with acute egg FPIES were enrolled, 34 (56%) males and 27 (44%) females. Tolerance to cooked egg has been demonstrated by 47/61 (77%) children at a mean age of 30.2 months. For 32 of them, tolerance to raw egg has been demonstrated at a mean age of 43.9 months. No episodes of severe adverse reaction after baked egg ingestion have been recorded. CONCLUSIONS: It is possible to perform an OFC with baked egg, to verify the possible acquisition of tolerance, at about 30 months of life in children with acute egg FPIES.

Predictive value of the number of adverse reaction episodes for the IgE-mediated food allergy diagnosis.

INTRODUCTION AND OBJECTIVES: The reproducibility of the adverse reaction increases the suggestiveness of a history of food allergy. However, the positive predictive value (PPV) of multiple adverse reaction episodes for the diagnosis of IgE-mediated food allergy is not known. This evaluation was the objective of our study. PATIENTS AND METHODS: We retrospectively studied 180 children with a history of non-anaphylactic adverse reactions after the ingestion of a food. All children had the prick test positive for the offending food and performed the oral food challenge (OFC) within 12 months after the last adverse reaction episode (ARE). We have evaluated whether increasing the number of ARE increased the probability that the OFC would be positive (failed). RESULTS: 93 patients (52%) presented one ARE, 49 (27%) presented two ARE, 24 (13%) presented three ARE, 14 (8%) patients presented≥four ARE. The OFC was positive in 94/180 (52%). The outcome of the OFC was found to be positively correlated with the number of ARE (OR=1.56; 95% CI=1.16-2.09; p=0.003). A PPV=100% was observed with a number of ARE≥five. CONCLUSIONS: The number of ARE is an important predictor of the diagnosis of food allergy, although less than we would have imagined. The number of ARE could be used to increase the predictability of the diagnostic tests currently in use, to define clinical prediction rules alternative to OFC and easy to use in clinical practice.

Prevalence of celiac disease in patients with severe food allergy.

The association between food allergy and celiac disease (CD) is still to be clarified. We screened for CD 319 patients with severe food allergy (IgE > 85 kU/l against food proteins and a history of severe allergic reactions) who underwent specific food oral immunotherapy (OIT), together with 128 children with mild allergy who recovered without OIT, and compared the prevalence data with our historical data regarding healthy schoolchildren. Sixteen patients (5%) with severe allergy and one (0.8%) with mild allergy tested positive for both genetic and serological CD markers, while the prevalence among the schoolchildren was 1%. Intestinal biopsies were obtained in 13/16 patients with severe allergy and in the one with mild allergy, confirming the diagnosis of CD. Sufferers from severe food allergy seem to be at a fivefold increased risk of CD. Our findings suggest that routine screening for CD should be recommended in patients with severe food allergy.

Paediatricians' attitudes toward pain in children with severe cognitive impairment. A regional survey.

INTRODUCTION: pain is a frequent and relevant problem in children with severe cognitive impairments. Assessing pain in these patients can be difficult. Specific observational tools such as the Collignon Giusiano Questionnaire or the Non-communicating Children's Pain Checklist ( NCCPC) are available, but their use is not widespread. Children with severe cognitive impairment are frequently in need of painful procedures but data about availability of procedural sedation in this setting are limited. OBJECTIVE OF THE STUDY: to evaluate paediatricians' attitudes toward pain in children with severe cognitive impairment by measuring the use of specific pain scales and the use of analgesia or procedural sedation in course of a frequent procedure such as botulinum toxin injection. METHODS: phone interview with the doctor on duty of 56 paediatric wards in 3 regions of the North East of Italy, addressing the routine use of pain scales, and the use of specific observational tools for non communicating children. A phone interview was also conducted in 4 centers routinely practicing botulinum toxin injection about the use of analgesia or procedural sedation. RESULTS: 1 centre out of 55 reported to use specific scales for children with cognitive impairment, specifically the Collignon Giusiano Questionnaire. No centre used procedural sedation for botulinum toxin injection. CONCLUSION: in the investigated area there is a lack of attention to pain in children with severe cognitive impairment. Specific educational efforts should be done to improve the quality of care in this setting.

Videogame playing as distraction technique in course of venipuncture.

BACKGROUND: Needle-related procedures (venipuncture, intravenous cannulation) are the most common source of pain and distress for children. Reducing needle related pain and anxiety could be important in order to prevent further distress, especially for children needing multiple hospital admissions. The aim of the present open randomized controlled trial was to investigate the efficacy of adding an active distraction strategy (videogame) to EMLA premedication in needle-related pain in children. METHODS: One-hundred and nine children (4 -10 years of age) were prospectively recruited to enter in the study. Ninety-seven were randomized in two groups: CC group (conventional care: EMLA only) as control group and AD group (active distraction: EMLA plus videogame) as intervention group. Outcome measures were: self-reported pain by mean of FPS-R scale (main study outcome), observer-reported pain by FLACC scale, number of attempts for successful procedure. RESULTS: In both groups FPS-R median rate was 0 (interquartile range: 0-2), with significant pain (FPS-R > 4) reported by 9% of subjects. FLACC median rate was 1 in both groups (interquartile range 0-3 in CC group; 0-2 in AD group). The percentage of children with major pain (FLACC > 4) was 18% in CC group and 9% in AD group (p = 0.2). The median of necessary attempts to succeed in the procedures was 1 (interquartile range 1-2) in both groups.. CONCLUSION: Active distraction doesn't improve EMLA analgesia for iv cannulation and venipuncture. Even though, it resulted in an easily applicable strategy appreciated by children. This technique could be usefully investigated in other painful procedures.

Deep sedation with propofol for upper gastrointestinal endoscopy in children, administered by specially trained pediatricians: a prospective case series with emphasis on side effects.

BACKGROUND AND STUDY AIMS: The need to administer procedural sedation to children has increased in recent years, as has experience in this field among nonanesthesiologists. Using propofol makes it easier to achieve sufficiently deep sedation. There is a considerable literature on the administration of propofol by nonanesthesiologists for gastroscopy in adults, but very few data are available on this issue in children. The aim of the present study was to assess the safety and efficacy of procedural sedation with propofol for gastroscopy in a pediatric ward with trained personnel and monitoring facilities. PATIENTS AND METHODS: A training protocol was developed to educate nurses and residents. Children requiring gastroscopy were included in the study prospectively and underwent procedural sedation with propofol administered by nonanesthesiologists. RESULTS: A total of 811 upper gastrointestinal endoscopies were carried out with procedural sedation. Sedation was achieved in all procedures, and all but three (0.4%) were conducted successfully. None of the patients required intubation. Stridor with signs of upper airway obstruction occurred in 14 of the 811 procedures (1.7%). Laryngoscopy was required to manage difficulties in introducing the gastroscope in 16 of the 811 procedures (2.0%). Major desaturation requiring a short course of ventilation occurred in six procedures (0.7%), and transient desaturation that resolved spontaneously occurred in 97 of the procedures (12%). CONCLUSIONS: Administration of propofol by nonanesthesiologists for gastroscopy examinations in children was successful in this study, but was associated with a small risk of potentially severe complications. Although the residents were generally able to administer procedural sedation alone, constant and immediate availability of anesthesiological support continues to be mandatory.
