RESUMEN
BACKGROUND: There is no evidence of the need for oxygen supplementation during upper digestive endoscopies under ketamine sedation in children, and the latest recommendations specifically state that it is not mandatory for the procedure. The aim of our study is to assess the incidence of respiratory adverse events during upper digestive endoscopies in children under Ketamine sedation when performed without oxygen supplementation, in accordance with the latest recommendations. METHODS: Eighty-eight children undergoing ketamine sedation for programmed upper digestive endoscopy at our Pediatric Intensive Care Unit were included. Patients needing other sedative agents different from ketamine were excluded. No patients received previous oxygen therapy. Suction equipment, oxygen, a bag-valve-mask, and age-appropriate equipment for advanced airway management were immediately available. The primary outcome measure was the incidence of desaturation episodes (i.e. FiO

BACKGROUND: Upper gastrointestinal endoscopies (UGEs) performed under ketamine sedation may increase the risk of respiratory adverse events (RAEs) due to pharyngeal stimulation. Topical lidocaine prevents general anesthesia-induced laryngospasm. OBJECTIVE: Our objective was to determine whether topical lidocaine may reduce the incidence of RAEs induced by pharyngeal stimulation in UGEs performed on children sedated with ketamine. METHODS: We conducted a single-center prospective study. We included every patient admitted for an elective diagnostic UGE under ketamine sedation who received lidocaine prior to the technique. Patients requiring any other medication were excluded. Our main outcome measure was the number of desaturation episodes. We then compared these results with those obtained in an historic group who did not receive topical lidocaine, in which we registered a total of 54 desaturation episodes. RESULTS: In total, 88 children (52.3% boys) were included. The median age was 7 years [interquartile range (IQR) 3-11]. The mean duration of the procedure was 6.5 ± 2.4 min, and the median initial ketamine dose was 1.76 mg/kg (IQR 1.56-2.03). The total number of desaturation episodes was 3 (3.4%), and two of these occurred prior to the introduction of the endoscope. This result represents a lower incidence than in previously reported series, and a significant decrease (p < 0.0001) with respect to the 54 RAEs registered in the historic group of 87 children. CONCLUSIONS: Topical lidocaine premedication significantly reduced the incidence of RAEs in children during UGEs under ketamine sedation. Our findings should be confirmed by a double-blind randomized controlled trial.

We describe a successful desensitization to alemtuzumab in one patient diagnosed with T-cell prolymphocytic leukaemia. Alemtuzumab treatment was initiated during infusion number 18, the patient showed cutaneous eruption with a miliary pattern, despite premedication with corticosteroids and antihistamines. The eruption returned with successive alemtuzumab infusions (infusions 19, 20 and 21), remained present for longer and was more severe with each infusion. The patient was referred to our Allergy Unit as it was necessary to maintain alemtuzumab treatment. Total immunoglobulin E level was 3 UI/ml and specific immunoglobulin E against more common pneumo-allergens, food, latex and hamster were inferior to 0.35 UI/ml. Prick test using the undiluted drug (30 mg/ml) and intradermal tests using serial dilutions (1/10, 1/100) were performed. The result of alemtuzumab skin prick test was 4 mm. The intradermal skin test result was positive at 1/100 dilution (papule: 8 mm; erythema: 12 mm). The basophil activation test with alemtuzumab was performed concluding that 10% of the basophils were activated by alemtuzumab. The patient underwent alemtuzumab desensitization according to a 12-step protocol that resolved to be safe and efficacious. Our experience may be helpful for similar clinical cases where the therapeutic options are very limited and a life-threatening condition such T-cell prolymphocytic leukaemia is present. In addition, a careful risk/benefit ratio should be considered and accurate informed consent is mandatory.

This randomized clinical trial was designed to determine whether glutamine administration was effective in reducing the incidence and severity of mucositis and dermatitis induced by radiotherapy (RT) or chemoradiotherapy (CHRT) in patients with head and neck cancer (HNC). Fifty patients were randomized to receive orally either L-Glutamine or placebo (25 patients in each arm). In the glutamine-treated group, 10 g of oral glutamine was administered three times daily. The primary endpoint was to compare the appearance of clinical mucositis between groups at the 6th week, according to the Common Terminology Criteria for Adverse Events. Secondary endpoints were: Functional mucositis, mucositis onset, cervicofacial dermatitis, pain, weight loss and assessment of quality of life (according to the M.D. Anderson Symptom Inventory-Head and Neck). In total, 76 and 87.5% developed clinical mucositis in the glutamine and placebo group, respectively. The incidence and severity grade of mucositis at the 6th week did not exhibit statistically significantly differences between the two groups, although it had a higher value in the placebo group. Significant reduction of dermatitis incidence (P=0.038) and severity (P=0.032) was found in the glutamine group. There were no differences in other outcomes such as pain, weight loss and mucositis onset, in treatment parameters including concomitant chemotherapy, radiation dose and previous surgery, or in quality of life. The present study revealed that glutamine provided slight clinical effects compared with placebo in terms of reducing oral mucositis induced by RT or CHRT in patients with HNC at the 6th week; however, the results were not statistically significant. Although the findings suggested a significant benefit in reducing the incidence and severity of dermatitis, further confirmatory studies are required.
RESUMEN
WHAT IS KNOWN AND OBJECTIVE: Dexmedetomidine (DEX) has been reported to be safe in paediatric patients. CASE DESCRIPTION: We present the case of a girl without heart disease admitted at our PICU due to an influenza A acute respiratory distress syndrome, who suffered a paroxysmal supraventricular tachycardia (PSVT) twelve hours after DEX progressive withdrawal was completed. WHAT IS NEW AND CONCLUSION: This is the first report of PSVT as an adverse reaction to DEX in a paediatric patient without heart disease.

BACKGROUND: Epilepsy is one of the most common symptoms in Tuberous Sclerosis Complex (TSC), appearing mainly in the first year of life and often resistant to therapy. Several studies have demonstrated the effectiveness of everolimus but its safety in children has not yet been well reported. We present two cases of severe pneumonia caused by Mycoplasma in two children receiving everolimus for epilepsy secondary to TSC. STUDY CASES: Both patients were admitted to the PICU for severe pneumonia with pleural effusion. One of them needed support with high concentration of oxygen and broad spectrum antibiotics and the other developed a septic shock with acute respiratory distress needing mechanical ventilation, vasoactive drugs, pleural drainage and broad-spectrum antibiotics. Everolimus was discontinued and in both patients Mycoplasma pneumoniae was identified by PCR. Both patients were discharged without sequelae. CONCLUSION: Everolimus therapy for epilepsy in the context of TCS could be associated, as in these two cases, with severe bacterial infection by Mycoplasma.
