22q11.2 microdeletion is the most common microdeletion in humans. The purpose of this study was to evaluate postoperative outcome in children with 22q11.2 microdeletion who had undergone complete surgical correction of a congenital heart defect. The study included 34 patients who underwent complete correction of conotruncal heart defects. Of these, 17 patients diagnosed with 22q11.2 microdeletion represent the investigated group. Another 17 patients without 22q11.2 microdeletion represent the control group. Investigated and control groups differ significantly for total length of stay in the hospital (average 37.35 and 14.12 days, respectively); length of postoperative stay in the intensive care unit (average 10.82 and 6.76 days, respectively); sepsis (eight and two patients, respectively); administration of antibiotics (15 and seven patients, respectively); duration of antibiotic therapy (average 17.65 and 14.59 days, respectively); occurrence of hypocalcemia (16 and 0 patients, respectively); and initiation of peroral nutrition during the postoperative course (average 10.29 and 3.88 days, respectively). No difference was found for duration of ventilatory support (average 6.12 and 4.24 days, respectively), administration of total parenteral nutrition, and postoperative mortality rate. The study results suggest that genotype of 22q11.2 microdeletion affects postoperative outcome after cardiac surgery. Possible targets for intervention in postoperative intensive care management are prevention and treatment of systemic infections, monitoring, and treatment of hypocalcemias, rational administration of antibiotics and careful planning of nutrition. Consequently, this could shorten patients' intensive care stay and overall duration of hospitalization.
Background. Mechanical ventilation is a frequently applied therapy in critically ill children and can be lifesaving in many cases. Clinical use of this technique has well documented benefits, but can be associated with different complications and adverse physiologic effects. Objectives. The aim of this study was to investigate the complications and clinical outcome of mechanical ventilation in Serbian pediatric patients. Material and Methods. The study encompassed 42 children with respiratory insufficiency that underwent mechanical ventilation during hospitalization over a period of 12 consecutive months. The influence of clinical and mechanical parameters on the occurrence of complications and clinical outcome were analyzed. Results. The patients were ventilated for a total of 432 days and a total of 61 complications were observed in 42 patients (97 complications per 1000 ventilation days). The most common complications associated with mechanical ventilation in Serbian pediatric patients with respiratory insufficiency were cardiovascular insufficiency (52.4%) and multiple organ failure (35.7%). High values of applied PIP (> 26 cm H 2 O), PEEP (> 6 cm H 2 O) and Tv (> 6 mL/kg) were associated with the occurrence of complications and negative clinical outcome. Conclusions. Complications of mechanical ventilation in the pediatric population occur frequently, but lower volumes/pressures of ventilation contribute to a decrease in incidence. Further studies are needed to examine associated risk factors and strategies to reduce the occurrence of complications and improve clinical outcome (Adv Clin Exp Med 2014, 23, 1, 57-61).
Drug hypersensitivity reactions (DHRs) are a type of adverse drug reactions with heterogeneous pathophysiological mechanisms and a broad spectrum of clinical manifestations. Since over-diagnosing is common in children, a complete allergy work-up is needed. A cross-sectional study was conducted at a tertiary care institution, covering the five-year period. Five hundred and four patients of both sexes, mean age 7.5 and with a medical history suggestive of DHR were evaluated. ENDA/EAACI guidelines were used for a diagnostic algorithm. Single drug hypersensitivity was registered in 375 patients and multiple drug hypersensitivity in 129. The main culprits in medical history were antibiotics (83%), non-steroidal anti-inflammatory drugs (NSAIDs) (8.4%) and analgoantipyretics (3.8%). Skin involvement was registered in 96.2%. DHRs were confirmed in 4.4% patients—six patients had positive skin tests and 13 had a positive drug provocation test. In the proven DHRs group, the main agents were antibiotics (72.7%), followed by NSAIDs (8.3%), and of all the skin manifestations, urticaria was most common (78.2%), followed by exanthema (10.5%) and angioedema (5.3%). Considering the above, anticipating DHRs and a proper referral of children to an allergologist is a key step in the assessment of drug hypersensitivity. A complete allergy work-up prevents unnecessary drug exclusion and allows most children to safely continue the use of first-line medications when needed.
Our center survival rate for CDH is in accordance with other reported studies. Based on our experience there are potential points for further improvement. First, further increase of prenatal detection, planning for delivery, and coordinated transfer to tertiary institution, in order to avoid transfer of near death patients. Second, preoperative management in the NICU. This could be done by more uniform implementation of current consensual guidelines in monitoring, mechanical ventilation and circulatory support of these delicate patients, together with rationale use of newer therapeutic resources.
Refractory convulsive status epilepticus (RCSE) is life-threatening condition, with seizures lasting over one hour and not responding to first and second-line anticonvulsant drug therapy. Any mistreatment or delayed proper treatment significantly increase mortality and neurologic sequelae. First line drugs for convulsion ceasing are benzodiazepines, phenobarbital and phenytoin. In case of refractory status, infusion of midazolam and general anesthesia should be administered. The most important measures of the intensive care are control of vital functions, homeostasis, prevention and therapy for possible brain and systemic complications. Discovery of etiology of status epilepticus is highly important because symptomatic therapy should be administered. Overall mortality rate during RCSE is 13.5%, and is much higher in acute symptomatic group--28.6%. Early sequelae rate is 40.6%, 27.3% and 70% in idiopathic and acute symptomatic groups, respectively.
Therapeutic recommendations for pediatric acute respiratory distress syndrome (PARDS) include conventional (CMV) and rescue high-frequency oscillatory mode (HFOV) of mechanical ventilation (MV). The pediatric risk of mortality (PRISM) is a frequently used mortality score for critically ill patients. In search of methods to recognize those patients, we analyzed the PRISM III score as a potential predictor of the short-term outcome in MV subjects with PARDS. A retrospective five-year study of PARDS in children on MV was conducted in the Pediatric ICU. Seventy patients were divided into two groups (age group <1 year and age group 1–7 years). The PRISM III score was used to assess the 28-day outcome and possible development of complications. The most common causes of PARDS were pneumonia and sepsis. Male sex, malnourishment, sepsis, and shock were significant indicators of poor outcome. The PRISM III score values were significantly higher in those who died, as well as in subjects requiring HFOV. The score had a significant prognostic value for short-term mortality. There was no significant difference in outcome based on the comparison of two modes of ventilation. A significantly higher score was noted in subjects who developed sepsis and cardiovascular insufficiency. The PRISM III score is a fair outcome predictor during the 28-day follow-up in MV subjects with PARDS, regardless of the ventilation mode.
In children, the incidence of Legionnaires’ disease (LD) is unknown, hospital-acquired LD is associated with clinical risk factors and environmental risk, and children with cell-mediated immune deficiency are at high risk of infection. Both newborns were born in the same delivery room; stayed in the same hospital room where they were cared for, bathed, and breastfed; were male; were born on time, with normal birth weight, and with high Apgar score at birth; and survived this severe infection (L. pneumophila, serogroup 2-15) but with different clinical courses. In neonate 1, bleeding in the brain, thrombosis of deep pelvic veins, and necrosis of the lungs, which left behind cystic and cavernous changes in the lungs, were found, while neonate 2 suffered from pneumonia alone. The only difference in risk factors for LD between these two newborns is the number of days of illness until the start of azithromycin treatment (sixth versus the third day of illness). We suggest that a change in the guidelines for diagnosing and treating community-acquired pneumonia and hospital-acquired pneumonia in newborns is needed in terms of mandatory routine testing for Legionella pneumophila. Early initiation of macrolide therapy is crucial for the outcome of LD in the newborn.
