Abstract
Systemic sclerosis sine scleroderma (ssSSc) is a rare variant of systemic sclerosis, with only one pediatric case reported in the medical literature to date. Pulmonary arterial hypertension as the presenting feature of ssSSc is extremely rare, even in adults, and so far has never been reported in children. We report, for the first time, a case of pediatric ssSSc in a 3-year-old girl, who presented with interstitial lung disease and pulmonary hypertension. The patient was prescribed early aggressive pulmonary vasodilators combined with anti-inflammatory medications. The clinical response was good, and her current condition at 12 years of age is remarkable, considering the high mortality rates reported in adults. We underscore the importance of early aggressive treatment in future cases of similar presentation.

Abstract
We examined the clinical and physiological benefits of heated humidified high-flow nasal cannula (HHHFNC) in treating pediatric bronchiolitis in a general pediatric ward. Children aged 0 to 2 years, hospitalized with moderate to severe bronchiolitis, were connected to HHHFNC. Each child was evaluated at 4- to 10-hour intervals, both on and off the device, using the Wang et al Bronchiolitis Severity score and transcutaneous CO2 monitor. Sixteen children were included in the final analysis. The Bronchiolitis Severity score improved by 3 points during the first and second intervals (P = .001). Transcutaneous CO2 values were reduced by an average 8.7 mm Hg (P = .001). No adverse effects were noted in children connected to the device. The HHHFNC device used in a general pediatric ward setting served as a safe and efficacious tool in treating moderate to severe bronchiolitis. Immediate clinical and physiological improvement was observed and maintained 1 to 4 hours after disconnection from the device.

Abstract
OBJECTIVE When bronchopulmonary dysplasia (BPD) is complicated by pulmonary hypertension (PH), morbidity and mortality are significantly increased. BPD-associated PH is not included in the current indications for PH medications. However, limited data demonstrate hemodynamic improvement and decreased mortality with PH-specific treatment. This report describes our 6-year experience treating BPD-associated PH with PH medications, mainly sildenafil. STUDY DESIGN The medical records of 20 infants diagnosed with BPD-associated PH at a tertiary pediatric pulmonary hypertension clinic in 2008-2014 were reviewed. Clinical improvement was defined as a decrease in Ross functional class by at least one degree. PH severity was classified by echocardiography as mild, moderate, or severe. Hemodynamic improvement was defined as a decrease in PH severity by at least one level. RESULTS Eighteen out of 20 patients were treated with PH medications: 12 sildenafil, 5 sildenafil and bosentan, and 1 bosentan. Median follow-up time was 2 years. Mean functional class significantly decreased from 3.2 ± 0.9 at diagnosis to 1.7 ± 0.9 at the last follow-up. Improvement in functional class was observed in 15/16 children (94%). Moderate or severe PH was found in 13/18 children (72%) at diagnosis, and in three (17%, all moderate PH) at the last follow-up. Improvement in PH class by echocardiography was demonstrated in 14/18 children (78%). The survival rate was 95%. CONCLUSION Treatment of BPD complicated by PH with PH-specific medications, mainly sildenafil, is associated with improvement in both clinical and hemodynamic parameters and a low mortality rate.

Abstract
The objective of this study was to define current blood transfusion practices among European pediatric intensive care physicians treating critically ill children. A questionnaire of case scenarios was administered to members of the European Society of Pediatric and Neonatal Intensive Care (ESPNIC). Of the 258 members of the ESPNIC, 134 (51.9%) pediatric intensive care physicians completed the questionnaire. The suggested blood transfusion thresholds for case scenario 1 (post–orthopedic surgery child) ranged from <7.0 g/dl to 11 g/dl. A total of 57.3% suggested 7 g/dl, 33.6% suggested 8 g/dl, and 6.9% suggested 9 g/dl as a hemoglobin threshold for transfusion (mean, 7.54 ± 0.75). For case scenarios 2 to 4, the suggested hemoglobin thresholds were 7 g/dl to 12 g/dl. For case scenario 2 (a child with acute respiratory distress syndrome), 22.4% suggested 8 g/dl, 15.7% suggested 9 g/dl, and 41% suggested 10 g/dl as a hemoglobin threshold for transfusion (mean, 9.40 ± 1.27 g/dl). For case scenario 3 (a post–cardiac surgery infant), 20.1% suggested 7 g/dl, 24.6% suggested 8 g/dl, 21.6% suggested 9 g/dl, and 23.9% suggested 10 g/dl as a hemoglobin threshold for transfusion (mean, 8.72 ± 1.24 g/dl). For case scenario 4 (a child with septic shock), 23.1% suggested 8 g/dl, 16.4% suggested 9 g/dl, and 41% suggested 10 g/dl as a hemoglobin threshold for transfusion (mean, 9.45 ± 1.24 g/dl). The threshold for transfusion was not statistically different ( P> .05) between the physicians according to their subspecialty, years of experience, or country of origin. The suggested volume of transfused blood was 10 to 15 ml/kg in 427 responses (82.6%) and 20 ml/kg in 89 responses (17.2%). Most physicians, 78/128 (60.9%), did not consider the age of the transfused blood an important factor in their decision to transfuse. Of the 106 (79.1%) physicians who detailed their considerations for elevating the thresh- old for transfusion, 82 (77.3%) gave a general nonspecific indication, 47 (44.3%) stated hemodynamic instability and shock, and 40 (37.7%) an ongoing bleeding. The hemoglobin threshold for blood transfusion and transfusion volume varies among European pediatric intensive care physicians, for the same patient.

Polymerase-chain-reaction-based diagnosis of viral pulmonary infections in immunocompromised children. Acta Paediatr 2013; 102:e263-8. [PMID: 23421914 PMCID: PMC7159754 DOI: 10.1111/apa.12207] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/14/2012] [Revised: 02/14/2013] [Accepted: 02/15/2013] [Indexed: 12/01/2022]
Abstract
Aim Viral pneumonia is a serious complication in immunocompromised children. Its aetiology is difficult to identify owing to the limitations of conventional microbiological tests. The aim of this study was to determine whether polymerase chain reaction (PCR) assays for respiratory viruses increase the diagnostic yield of bronchoalveolar lavage (BAL) in immunocompromised children. Methods BAL samples obtained from immunocompromised children hospitalized with pneumonia were processed for respiratory viruses by viral culture, rapid antigen test and PCR (for CMV, adenovirus, influenza, parainfluenza, herpesvirus, RSV and hMPV). Results The study group included 42 patients (mean age 7.2 ± 5.1 years) with 50 episodes of clinical pneumonia (50 BAL samples). Forty viral pathogens were identified in 30 episodes (60%). PCR increased the diagnostic rate by fourfold (75% identified by PCR alone, p < 0.0001). When viral culture and rapid antigen test were used as the gold standard, PCR was found to have high sensitivity (86–100% when assessed) and specificity (80–96%). The PCR results prompted the initiation of specific antiviral therapy and the avoidance of unnecessary antibiotic treatment in 17 (34%) episodes. Conclusion PCR‐based diagnosis from BAL may increase the rate of pathogen detection in immunocompromised children, decrease the time to diagnosis and spare patients unnecessary antimicrobial treatment.

Abstract
OBJECTIVE Fungal pneumonia is a serious complication in immunocompromised children. It is difficult to diagnose because of the low sensitivity of clinical and standard laboratory tests. The aim of this study was to investigate the diagnostic impact of polymerase chain reaction (PCR) assays for fungal pathogens in bronchoalveolar lavage (BAL) fluid. STUDY DESIGN BAL samples obtained from hospitalized immunocompromised patients with clinical pneumonia between January 2007 and June 2009 were processed for microscopy and cultures in addition to PCR-based fungal assays. The results were compared between the standard and PCR methods. RESULTS Seventy-seven children with 100 episodes of pneumonia were included in the study. Fungal pathogens were detected by standard microbiological investigations in 10 episodes (10%) and by PCR-based assays alone in 20 episodes (20%). There was no significant difference in clinical improvement or mortality rate between patients diagnosed by the different methods. In 61 episodes, no fungal pathogen was identified by either method. Prolonged antifungal therapy was avoided in 43 episodes. CONCLUSION PCR-based assay for the diagnosis of fungal pulmonary infections may be a useful adjunct to clinical and standard microbiological techniques. The use of PCR may decrease the time to diagnosis, increase the rate of detection of fungal pathogens, and spare patients unnecessary antifungal treatment.

Abstract
Catastrophic antiphospholipid syndrome (APS) in pediatric medicine is rare. We report 3 adolescents who presented with acute onset of severe abdominal pain as the first manifestation of probable catastrophic APS. The 3 patients, 2 male patients and 1 female patient were 14 to 18 years old. One had been diagnosed with systemic lupus erythematosus in the past, but the other 2 had no previous relevant medical history. All presented with excruciating abdominal pain without additional symptoms. Physical examination was noncontributory. Laboratory results were remarkable for high inflammatory markers. Abdominal ultrasonography was normal, and abdominal computed tomography scan showed nonspecific findings of liver infiltration. Only computed tomography angiography revealed evidence of extensive multiorgan thrombosis. All patients had elevated titers of antiphospholipid antibodies. The patients were treated with full heparinization, high-dose steroids, and intravenous immunoglobulin with a resolution of symptoms. One patient was resistant to the treatment and was treated with rituximab. In conclusion, severe acute abdominal pain can be the first manifestation of a thromboembolic event owing to catastrophic APS even in previously healthy adolescents. Diagnosis requires a high index of suspicion with prompt evaluation and treatment to prevent severe morbidity and mortality.

Abstract
HPS is rare in the pediatric population. Liver transplantation is the ultimate treatment for severe HPS. There are only a few case reports and one series of children in whom HPS was the main indication for liver transplantation. Outcome was good in most of them, with full regression of the pulmonary process. However, hypoxemia in the early post-operative course can have severe consequences, and effective treatment modalities are needed. There are rare instances of the use of iNO for the treatment of post-operative hypoxemia. We describe a 10.5-yr-old boy with severe HPS owing to chronic liver disease after bone marrow transplantation. Liver transplantation from a living related donor (the same sister who donated the bone marrow) was complicated by severe hypoxemia on POD 2. iNO was administered via the ventilator circuit and, after extubation, through nasal prongs. It was slowly tapered down and stopped on POD 10. The child had an otherwise uneventful course and was discharged home on POD 21 with normal oxygen saturation. Liver transplantation should be offered to children with severe HPS. iNO can reverse the hypoxemia that may occur after the operation.

Abstract
Thrombotic thrombocytopenic purpura is caused by an imbalance of von Willebrand factor and its cleaving protease, which leads to the formation of microthrombi in end-organs. It rarely occurs in the pediatric population. Plasma exchange can significantly reduce mortality and morbidity. We present a 14-month-old infant in whom clinical and laboratory abnormalities compatible with thrombotic thrombocytopenic purpura were noted several days after resection of a large pelvic tumor. Treatment with double volume plasma exchange on postoperative day 5 led to complete resolution of the renal failure, thrombocytopenia, anemia, and neurological manifestations. ADAMTS13 inhibitors were negative and no mutations were found in factor H, factor I, membrane cofactor protein, and thrombomodulin to account for genetic predisposition to thrombotic thrombocytopenic purpura or atypical hemolytic uremic syndrome. Postoperative anemia, thrombocytopenia, fever, and neurological deficits in children should raise the suspicion of thrombotic thrombocytopenic purpura. Early diagnosis is important because the disorder is readily and efficiently treated with plasma exchange.

Abstract
AIM To further characterize apnoea(s) complicating bronchiolitis because of respiratory syncytial virus (RSV), to describe the incidence of this complication and identify possible risk factors for apnoea(s) and its development. METHODS The files of infants admitted to the paediatric intensive care unit (PICU) for RSV bronchiolitis during three bronchiolitis seasons (2004-2007) were reviewed for demographic, clinical and laboratory parameters. Parameters were compared between patients with and without apnoeas. RESULTS Seventy-nine patients met the study criteria: 43 were admitted to the PICU for central apnoeas and the remainder for respiratory distress or failure. The percentage of infants admitted for apnoea increased during the study period (28.6 to 77.1%, p = 0.004). The overall prevalence of apnoea in this population was 4.3%. Possible risk factors for apnoea(s) were younger age (1.3 vs. 4.3 months, p = 0.002), lower admission weight (3.3 vs. 5 kg, p < 0.001), lower gestational age (35.8 vs. 37.8 weeks, p = 0.01), admission from the emergency room (50% vs. 9.1%, p < 0.001) and lack of hyperthermia (p < 0.001). Respiratory acidosis was found to be a protective factor on logistic regression analysis. CONCLUSION The prevalence of apnoea in infants admitted to the PICU for RSV bronchiolitis in our centre may be increasing. Preterm, younger infants with no fever are at relatively high risk of apnoea at presentation, while older infants with fever are at lower risk.

Abstract
The aim of the study was to describe our experience with bi-level positive airway pressure (BiPAP) ventilation in oncology children with acute respiratory failure, hospitalized in a single tertiary pediatric tertiary center. This was a retrospective cohort study of all pediatric oncology patients in our center admitted to the intensive care unit with acute hypoxemic or hypercarbic respiratory failure from January 1999 through May 2006, who required mechanical ventilation with BiPAP. Fourteen patients met the inclusion criteria with a total of 16 events of respiratory failure or impending failure: 12 events were hypoxemic, 1 was combined hypercarbic and hypoxemic, and 3 had severe respiratory distress. Shortly after BiPAP ventilation initiation, there was a statistically significant improvement in the respiratory rate (40.4 ± 9.3 to 32.5 ± 10.1, P < .05] and a trend toward improvement in arterial partial pressure of oxygen (PaO 2; 71.3 ± 32.7 to 104.6 ± 45.6, P = .055). The improvement in the respiratory status was sustained for at least 12 hours. In 12 (75%) events there was a need for sedation during ventilation; 12 children needed inotropic support during the BiPAP ventilation. Bi-level positive airway pressure ventilation failed in 3 (21%) children who were switched to conventional ventilation. All of them have died during the following days. One child was recategorized to receive palliative care while on BiPAP ventilator and was not intubated. In 12 of 16 BiPAP interventions (75%; 11 patients), the children survived to pediatric intensive care unit (PICU) discharge without invasive ventilation. No major complications were noted during BiPAP ventilation. Bi-level positive airway pressure ventilation is well tolerated in pediatric oncology patients suffering from acute respiratory failure and may offer noninferior outcomes compared with those previously described for conventional invasive ventilation. It appears to be a feasible initial option in children with malignancy experiencing acute respiratory failure.

Abstract
OBJECTIVE To investigate etiology and airway management in children with tracheobronchomalacia. METHOD Bronchoscopic examinations were performed in 671 children. The cases with tracheomalacia and bronchomalacia were analyzed in etiopathogenesis and summarized their therapy simultaneously. RESULT Bronchoscopic examination indicated tracheomalacia and bronchomalacia in 148 cases, tracheomalacia in 77 cases and bronchomalacia in 71 cases. Among the cases with tracheomalacia, compression by vascular rings was found in 46 cases, incorporated congenital esophageal atresia with tracheoesophageal fistula was found in 5 cases, tracheomalacia was associated with tracheostoma and mechanical ventilation in 6 cases, with congenital airway malformation in 11 cases and isolated tracheomalacia was found in 4 cases. Among the cases with bronchomalacia, incorporated congenital cardiovascular malformation was found in 64 cases, congenital airway malformation in 6 cases and isolated bronchomalacia in 1 case. Ten children with anomalous innominate artery underwent aortopexy, twelve children with dextro-aorta arch with concomitant aberrant left subclavian artery and double aorta underwent arches vascular ring lysis, six children with pulmonary sling underwent plasty. Severe malacia segments were resected directly in four children during operation. Mechanical ventilation was performed in 38 children. Tracheostoma was performed in 4 children to treat tracheomalacia and bronchomalacia, it could relieve symptom to a certain extent. In 2 children metal stents were inserted into the bronchus for the treatment of bronchomalacia, one was successful and the other needed re-insertion of stent again, these two patients underwent balloon-dilatation in distal part of stent afterwards. CONCLUSION The congenital cardiovascular malformation was the main reason to develop tracheobronchomalacia in children. The symptom of majority of the cases with cardiovascular malformation would be improved within 6 months after surgical intervention. In severe cases, treatments included mechanical ventilation and tracheostoma. Stenting could be applied in refractory cases, but it had certain limitations.

Abstract
Objectives: Foreign body aspiration (FBA) is a life-threatening event in children. The gold standard for diagnosis is bronchoscopy, but there is no consensus regarding indications for the procedure. The aim of this study was to formulate a predictive model for assessing the probability of FBA in suspected cases as an aid in the decision to perform diagnostic bronchoscopy. Methods: The files of 150 patients who underwent bronchoscopy for suspected FBA at our center between 1996 and 2004 were reviewed for medical history, physical examination, and radiologic studies. The findings were analyzed by logistic regression. Results: Using the file data, we formulated a predictive model wherein each parameter received a numeric coefficient representing its significance in evaluating suspected FBA. The most significant parameters were age 10 to 24 months, foreign body in the child's mouth and severe respiratory complaints during the choking episode, hypoxemia, dyspnea or stridor following the acute event, unilateral signs on lung auscultation, abnormal tracheal radiogram, unilateral infiltrate or atelectasis, and local hyperinflation or obstructive emphysema on chest radiogram. Conclusions: In our predictive model, every case of suspected FBA can be assigned a score based on the specific parameters present, which is then entered into a probability formula to determine the likelihood of a positive diagnosis. This model may serve as a useful tool for deciding on the use of bronchoscopy in all children with suspected FBA.

Abstract
STUDY OBJECTIVES To assess the effect of palivizumab licensing for respiratory syncytial virus (RSV) prophylaxis on national pediatric ICU (PICU) admissions and on the need for mechanical ventilation due to RSV bronchiolitis in Israel. DESIGN Prospective national surveillance survey. SETTING All PICUs in Israel. PATIENTS OR PARTICIPANTS All patients admitted to a PICU because of acute bronchiolitis in two consecutive RSV seasons (November 2000 to April 2001 and November 2001 to April 2002). METHODS Data on demographic and epidemiologic factors and RSV prophylaxis status were collected for every infant with bronchiolitis who was admitted to a PICU in Israel in the year before and after issuance of the Israel Ministry of Health recommendation for palivizumab prophylaxis (January 2001). RESULTS One hundred five patients were admitted to a PICU because of RSV bronchiolitis in the year before the recommendations were issued, and 123 patients were admitted in the year after they were issued. Mechanical ventilation was required by 33 and 42 children, respectively. Gestational age was > 32 weeks in 92.9% and 83.9% of the admitted patients, respectively, and 89% and 91% of the patients, respectively, were free of chronic lung disease (CLD). In both periods, 83% of the children who were admitted to a PICU did not meet the American Academy of Pediatrics criteria for RSV prophylaxis. CONCLUSIONS Most of the children with severe RSV bronchiolitis needing PICU admission from 2000 to 2002 born at term did not have CLD and were not candidates for RSV prophylaxis according to the current recommendations.

Abstract
OBJECTIVES To investigate the management of children with life-threatening airway obstruction from large mediastinal masses. METHODS Review of the medical records of children with mediastinal masses and severe airway obstruction who were admitted to a multidisciplinary pediatric intensive care unit. RESULTS Eight patients with 12 life-threatening events were identified. Five events (in 4 patients) occurred before hospital admission, and 3 patients had more than 1 choking episode. Five patients underwent cardiorespiratory resuscitation (2 before admission), and 2 underwent emergency endotracheal intubation because of severe airway obstruction; the eighth patient could not be weaned off the ventilator until the mediastinal mass was resected. Median time from appearance of the initial symptoms to diagnosis was 8.5 days, and median time from the onset of alarming signs to admission was 2 days. CONCLUSIONS Severe airway obstruction in children with an anterior mediastinal mass is not rare and can lead to complete obstruction, requiring cardiorespiratory resuscitation. Physician awareness and preparedness for respiratory complications are essential for proper management of children with mediastinal masses.

Abstract
This study highlights the less common presentations of Hirschsprung disease (HD) and HD-associated enterocolitis (HAE) in neonates and infants. We present three infants whose diagnosis was delayed because of atypical presenting features, especially with failure to gain weight, decreased appetite, episodes of diarrhoea and vomiting and hypoalbuminaemia. The reported incidence of HAE ranges from 0 to 16.2%. To avoid complications of life-threatening HAE, primary care physicians require a high index of suspicion of the more unusual presentations of HD in neonates and infants.

Abstract
OBJECTIVE Preterm infants, especially those with chronic lung disease (CLD), are considered more susceptible to severe respiratory illness from respiratory syncytial virus (RSV) infection than healthy term infants, and are therefore targeted for prophylactic administration of immune globulins. The impact of this practice on the more severe cases of bronchiolitis (i.e., pediatric intensive care unit [PICU] admission, mechanical ventilation, mortality) has not been reported to date. The aim of this study was to evaluate PICU admissions, need for mechanical ventilation, and mortality attributable to RSV bronchiolitis in Israel before the introduction of RSV prophylaxis to the country. DESIGN AND SETTING Prospective survey of 11 PICUs in Israel during the RSV season (November 2000-March 2001). PATIENTS All patients admitted to the PICU because of bronchiolitis, and the subgroups who needed mechanical ventilation or who died, were analyzed for known risk factors, namely, prematurity, CLD, and chronic oxygen dependence. RESULTS A total of 105 patients with RSV bronchiolitis met the inclusion criteria, of whom 33 were mechanically ventilated. Most of the patients (84% total admission, 88% ventilated) were born after 32 weeks' gestation, and 89% and 88%, respectively, did not have CLD. Only 16% and 9%, respectively, met any of the American Academy of Pediatrics criteria for RSV prophylaxis, such that 84% of the whole sample and 91% of the ventilated patients were not candidates for RSV prophylaxis. Five patients died, 2 of them with cyanotic heart disease. CONCLUSIONS Most of the infants with severe RSV bronchiolitis were born at term and did not have CLD. The great majority of patients admitted to the PICU for bronchiolitis were not candidates for RSV prophylaxis. Administration of RSV prophylaxis to the predefined high-risk population could be expected to yield no significant change in PICU admissions or number of infants needing mechanical ventilation. New risk-stratified guidelines for RSV prophylaxis are needed.

Abstract
BACKGROUND Rapid institution of ventilatory support is mandatory in apneic victims of nerve agents (NA) if fatal outcome is to be avoided. The Hayek oscillator (HO)-a high frequency external ventilator can provide non-invasive ventilatory support based on a cuirass tightly fit around the patient chest. Our aim was to investigate the feasibility of provision of resuscitative ventilatory support using the HO to cats poisoned by Dichlorovos (DDVP) an OP and NA-like compound. MATERIAL/METHODS DDVP, 150 mg/kg was administered per os to 10 cats. With the appearance of the first signs of intoxication, the animals were treated with atropine 0.1 mg/Kg. Then, animals were randomly divided into two equal groups: 1) control (no further treatment) or 2) experimental: ventilation using the HO with the following setup: 240 cycles/min, inspiratory and expiratory pressure of -22 and -2 cm H2O respectively and I/E ratio of 1/1. RESULTS The control cats died within 4-9 min from the initial appearance of signs of systemic poisoning. The experimental 5 cats survived and regained spontaneous breathing ventilation 3 hr thereafter. The use of the HO enabled also clearance of bronchial secretion saving the need for active suctioning of the airways. CONCLUSIONS The provision of external high frequency oscillation using the HO may serve as a useful and easily applied mode of ventilation in case of urgent need to resuscitate mass casualties suffering from NA poisoning in the prehospital setting. Its advantages include: lack of need for laryngoscopy and intubation and enhanced clearance of secretions.

Abstract
OBJECTIVE Several clinical guidelines exist for blood transfusion in adults but only one refers to children. There are no guidelines for blood transfusion in critically ill children and the paediatric intensive care specialist's approach is unknown. We wished to evaluate the approach toward blood transfusion among a group of paediatric intensive care specialists. METHODS All certified paediatric intensive care specialists from the Israeli society of pediatric intensive care medicine were requested to complete a questionnaire, which described four hypothetical common scenarios in paediatric intensive care units. In each case, the physicians were asked to denote the haemoglobin threshold at which they would prescribe a blood transfusion and the transfusion volume they would use. The specialists were also asked for their reasons for increasing their haemoglobin threshold for blood transfusion. RESULTS The questionnaire was posted to twenty six paediatric intensive care specialists, twenty one of whom responded (i.e. 80.8%). There was a wide variation for each scenario in both the suggested haemoglobin thresholds for transfusion (varying by 20-50 g/L) and the transfusion volume (varying by 10-20 mL/kg). The reasons given for increasing their blood transfusion threshold included, in order of importance, shock, haemodynamic instability and hypoxaemia. CONCLUSIONS There is a marked variability among paediatric intensive care specialists regarding both the threshold haemoglobin level at which blood transfusion is prescribed as well as the volume used.

Abstract
BACKGROUND Blood stream infections are a common and serious complication of central venous catheters (CVCs). To decrease catheter colonization, some authors advocate tunneling the catheter in the subcutaneous tissue during insertion. This technique has proved effective in adults, but there are no data on its safety and efficacy in critically ill children. Our objective was to evaluate the efficacy and safety of subcutaneous tunneling of short term, noncuffed CVCs for the prevention of CVC-related infections in critically ill children. METHODS A prospective randomized controlled trial was performed at a tertiary children's medical center in Israel and included children ages 0 to 18 years admitted to the pediatric intensive care unit or the pediatric cardiac intensive care unit from September 2000 to April 2001 who required placement of a femoral central venous catheter for >48 h. The children were randomized for tunneled or nontunneled insertion. The main outcome measures were bacterial colonization of proximal and distal catheter segments tested by semiquantitative technique and infectious or noninfectious complications of the CVC. RESULTS Of 98 eligible children, 49 received tunneled catheters and 49 received nontunneled catheters. Patients' age ranged from 1 month to 16.5 years (mean, 3.07 +/- 2.48 years). There were no significant differences between the groups in age, sex, disease severity [Pediatric Risk of Mortality III (PRISM) score], duration of catheterization and underlying diseases. Bacterial colonization was found in 11 (22.4%) catheters in the nontunneled group compared with 3 (6.1%) in the tunneled group (P = 0.004). Proximal segment colonization occurred in 7 (14.2%) nontunneled catheters and 2 (4.8%) tunneled catheters (P = 0.07), and distal segment colonization occurred in 3 (6.1%) and 9(18.3%) tunneled and nontunneled catheters, respectively (P = 0.053). The main pathogens were coagulase-negative staphylococci, Pseudomonas spp. and Klebsiella spp. There was no statistically significant difference between the groups in the rate of bloodstream infection (2 in the tunneled group, 3 in the nontunneled). Except for 1 case of subcutaneous hematoma, which resolved, there were no immediate or late complications of the tunneling procedure. CONCLUSION Subcutaneous tunneling of CVCs in the femoral site is a safe procedure and decreases significantly the rate of CVC colonization in critically ill children.

Abstract
Mediastinal masses in children are a heterogeneous group of asymptomatic or potentially life-threatening congenital, infectious, or neoplastic lesions that present complex diagnostic and therapeutic dilemmas. Some patients are asymptomatic; in others, the mass may compress mediastinal structures and cause sudden asphyxia. In these cases, close cooperation is needed among pediatric surgeons, anesthesiologists, intensivists, oncologists, and radiologists. The files of 45 children with mediastinal masses admitted between 1986 and 1999 to the Pediatric Intensive Care Unit (PICU) of Schneider Children's Medical Center of Israel were reviewed. Twenty-one were admitted for perioperative care, and 21 for emergency care, including 19 with respiratory distress. Five of the emergency care group had asphyxia and 10 needed assisted ventilation. Two children were admitted for evaluation and 1 for leukopheresis. The children admitted on an emergency basis had more clinical findings than the postoperative group: almost 80% had dyspnea and more than 45% had oxygen desaturation; 33% had cough and noisy breathing, and 25%, superior vena cava syndrome or hepatosplenomegaly. Eight patients (17.8%) had benign disease and 37 (82.2%) malignant disease. The patients with a benign mass were significantly younger than the patients with a malignant mass (p<0.005); in 5 cases (12.5%), a congenital anomaly presented as a mediastinal mass. Most of the malignant masses were of hematologic origin (40.5%), followed by neurogenic tumors (27%). Twenty-seven patients underwent surgery, including 6 emergency procedures (3 partial resections, 2 biopsies, 1 lymph node biopsy). There were no intraoperative or postoperative deaths. The present series emphasizes the complex care children with a mediastinal mass require. They should be treated in a tertiary center with a multidisciplinary approach.

Abstract
We report a case of an infant with an extensive hemangioma encompassing the thoracic aorta, associated with complex coarctation. Surgical approach was abandoned for fear of bleeding. The complexity of the coarctation made it unsuitable for balloon dilation. We implanted a stent with significant angiographic improvement and resolution of systemic hypertension.

Abstract
A 3 1/2-year-old child developed unilateral diaphragmatic paralysis after chest drain insertion. Plain chest X-ray demonstrated paravertebral positioning of the chest-tube tip, and magnetic resonance imaging revealed hematomas in the region of the chest-tube tip and the phrenic nerve fibers. The trauma to the phrenic nerve was apparently secondary to malposition of the chest tube. This is a rare complication and has been reported mainly in neonates. Radiologists should notify the treating physicians that the correct position of a chest drain tip is at least 2 cm distant from the vertebrae.

Abstract
OBJECTIVE To describe the rare, dramatic, presentation of benign occipital epilepsy. METHODS We describe three children who presented to the pediatric emergency department from 1992 to 1996 with a clinical picture of catastrophic intracranial event. RESULTS The main signs and symptoms were loss of consciousness in all patients, apnea in two, hemiclonus in two, general hypertonicity in two, eye deviation in two, fixed dilated pupils in one, and decorticate rigidity in two. All underwent emergency intubation, brain scan, and lumbar puncture, and all were treated with antibiotics, in addition to antiviral drugs in two. Two patients were also treated for suspected increased intracranial pressure. Two patients recovered within a few hours and one within 24 hours of admission without any residual neurologic deficit. Electroencephalograms, done within 48 hours after the event, revealed the classic pattern of occipital epilepsy in two patients and bilateral occipital slow wave in one. A 3- to 5-year clinical and electroencephalographic follow-up supported the diagnosis. CONCLUSION Benign occipital epilepsy in children can mimic a catastrophic intracranial event. Electroencephalography, performed early in the Pediatric Intensive Care Unit, may avoid or shorten unnecessary and aggressive treatments such as hyperventilation, diuretic agents, and prolonged antiviral therapy.

Abstract
Acute disseminated encephalomyelitis is a demyelinating syndrome that occurs infrequently in children. Various treatment modalities, such as plasmapheresis or steroids or intravenous immunoglobulins (IVIG), have been prescribed. The article describes the results of combined IVIG and high-dose steroids given for 3 days in the treatment of a patient with atypical encephalomyelitis. The results suggest that this approach may be more beneficial than the application of either drug alone.

Abstract
A study was undertaken to retrospectively evaluate the yield of bronchoalveolar lavage (BAL) in a single-institution series of children after bone marrow transplantation (BMT) and to compare the yield of BAL between the ventilated and nonventilated patients. We reviewed charts of 52 consecutive children after BMT who underwent BAL. Thirty patients (41 BALs) were nonventilated (group 1) and 33 patients (45 BALs) were ventilated for respiratory failure (group 2). Eleven patients were included in both groups. BAL was performed a median of 255 and 28.5 days after BMT in groups 1 and 2, respectively (P < 0.001). Group 1:17 pathogens were isolated from 13 BALs; a single pathogen from 10 BALs. Group 2:15 pathogens were isolated from 14 BALs (31.1% positive). Viruses were isolated from 13 BALs in group 2. A severe complication of BAL occurred in only one patient from group 1 (1.1%). Open lung biopsies were performed in one patient in group 1 and eight patients in group 2. The histological findings correlated with the BAL findings in 66.7%. In conclusion, there was no difference in the yield of BAL between the groups. Therapy was changed in one third of the patients dictated by the BAL findings. The risk of severe complications was relatively low. A good correlation between open lung biopsy (OLB) and BAL was found.

Abstract
OBJECTIVE: To describe an often-unrecognized clinical picture of multiple organ failure in hemophagocytic lymphohistiocytic syndrome (HLS). DESIGN: Retrospective chart review. SETTING: A ten-bed pediatric intensive care unit (PICU) in a tertiary children's university hospital. PATIENTS: A total of 11 children (age, 5 months to 13 yrs) who fulfilled the criteria for the diagnosis of familial- or infectious-associated hemophagocytic lymphohistiocytosis and who required intensive care support for organ failure. INTERVENTION: None. MAIN RESULTS: During a 10-yr period, 5,439 children were hospitalized in our PICU. A total of 11 children were diagnosed as suffering with HLS. Of these 11 patients, three (27%) had the familial form and eight had the infectious-associated form. After admission to the PICU, seven patients (63%) were diagnosed as suffering with HLS and each had one or more organ failures (patients 3-7, 9, and 10). All presented with fever, hepatomegaly, and splenomegaly; in addition, all had at least two of the following: anemia, neutropenia, or thrombocytopenia. All 11 had lymphohistiocytic accumulation in bone marrow (n = 10), lymph node (n = 2), lung (n = 2), and/or liver (n = 1). Organ failure was noted most often in the respiratory system (n = 7) attributable to severe, acute respiratory distress syndrome and pleural effusion. Of the 11 patients, six had cardiovascular involvement that manifested as shock in three and as capillary leak syndrome in three. Renal failure occurred in four patients. Of these, two required hemodiafiltration and one required peritoneal dialysis. Liver failure occurred in three and central nervous system involvement and coma in three. Most of the patients required massive therapeutic intervention, including assisted ventilation (n = 6), inotropic support (n = 3), and hemofiltration (n = 3). A total of seven patients (63%) died. CONCLUSIONS: Hemophagocytic lymphohistiocytic syndrome in the pediatric population may have a dramatic clinical picture, with multiple organ failure as a presenting symptom or early in the disease course, mandating intensive support in the PICU.

Abstract
An infant with cystic fibrosis and her asthmatic father were diagnosed as suffering from allergic bronchopulmonary aspergillosis (ABPA). Cystic fibrosis was diagnosed in the infant at 6 weeks of age, and gene mutations were W1282X/G542X. She was diagnosed definitively as suffering from ABPA at age 3.5 years, but had suggestive symptoms from age 11 months. This may be the youngest age described to date for ABPA. The child responded well to systemic steroid therapy, but remained steroid-dependent over the next 4 years. Treatment with itraconazole enabled a marked reduction in steroid dosage. The father was an asthmatic, and a heterozygote for the cystic fibrosis transmembrane regulator (CFTR) mutation W1282X. He had a normal sweat test, atopy, and moderate reversible airway obstruction. There was no proven exposure to Aspergillus in the home environment. The importance of considering the diagnosis of ABPA even in infancy, the therapeutic dilemmas, and the possible role of abnormal CFTR function in the development of ABPA are discussed.

Abstract
Open lung biopsy (OLB) is an important diagnostic tool in children with immune deficiency and/or chronic lung disease with diffuse pulmonary compromise. These patients require a tailored therapeutic approach owing to their fragile status and the side effects of unnecessary or inadequate treatment. Twenty-six patients of mean age 5.6 y underwent 41 open lung biopsies in our centre between 1991 and 1995. Seventeen (65%) were immunocompromised (including 13 with malignancy) and 9 had other lung diseases. The biopsies were diagnostic in 25 patients (96%), and complete clinical-pathological correlation was found in 11 (42%). A specific infectious aetiology was detected in nine patients (35%), all of them immunocompromised. Therapeutic changes were instituted on the basis of the biopsy findings in 18 patients (69%). Two patients had postoperative complications (prolonged pleural leak). We conclude that OLB is a safe diagnostic procedure even in the critically ill child and should be employed without hesitation when conventional methods fail to provide a definitive diagnosis to help redirect therapy.

Abstract
Children with primary combined immunodeficiency (CID) and human cytomegalovirus (HCMV) infection often deteriorate despite antiviral therapy. In this study, the emergence of ganciclovir-resistant strains was examined in 6 children with CID and HCMV infection, using sequence analysis of the HCMV UL97 gene and virus susceptibility assays. Mutations in the proposed ATP binding site associated with ganciclovir resistance were found in 4 of the 6 children. In 1 patient with B severe CID, an unusual multiplicity of mutations was found in the UL97 substrate binding domain between aa 590-606. All mutations were detected within 10 days to 3 weeks from initiation of therapy. The emergence of resistant strains in children with CID appears earlier than in other groups of HCMV-infected patients. These findings may have relevance to the cellular pathways involved in viral DNA repair and mutagenesis, and they indicate the need for early and frequent genotypic monitoring and prompt therapeutic modification in this patient population.

UNLABELLED Herpes simplex virus (HSV) is an uncommon cause of acute laryngitis in immunocompetent patients since it mostly occurs in immunocompromised subjects. We present two previously healthy children with prolonged gingivostomatitis and stridor (lasting 3 and 4 weeks) in whom HSV-1 was isolated from subglottal ulcers. CONCLUSION HSV should be considered a possible pathogen in cases of prolonged or atypical croup not only in immunocompromised or elderly patients but also in otherwise healthy children.

Abstract
Overnight polysomnography (PSG) has been used to diagnose and assess the severity of obstructive sleep apnoea syndrome (OSAS) in children. The aim of this study was to determine whether home video-recording of children during sleep may be used for screening OSAS. In 58 children suspected of having OSAS, PSG results were compared with the corresponding analyses of 30 min video-recordings of each child sleeping at home. The video-recordings were evaluated by: 1) overall investigator's clinical judgement; and 2) a scoring system based on noisy breathing, movements, walking episodes, apnoea, chest retractions and mouth breathing. PSG results were highly correlated with the video test results, with agreement in 49 out of 58 (84%). In 36 of the 58 children, the PSG was abnormal compared with 41 out of 58 abnormal video tests. The sensitivity of the overall investigator judgement of video test was 94% (34 out of 36) and the specificity 68% (15 out of 22). Video scores > 10 were highly predictive of OSAS, whilst scores < 5 were associated with normality. Using a stepwise logistic regression analysis, each of the scoring variables was tested against the PSG results and an equation was formulated for predicting PSG by the video test. The equation predicted PSG results in 49 out of 58 (84%) cases. Thirty minutes of home video-recordings during sleep is a reliable screening method for obstructive sleep apnoea syndrome in children. This technique may, thus, improve patient selection for polysomnography.

Abstract
We studied the epidemiology and incidence of the sudden infant death syndrome (SIDS) in the Tel Aviv and Petah Tikva districts during the period April 1980 to March 1983. Sixty-nine infants were diagnosed as SIDS and 38 of them had autopsies. Four cases were excluded because their autopsy revealed other diagnoses. When calculating for 24,183 live births per year during the study period, the rate of SIDS was found to be 0.47-0.90:1,000 live births. Other epidemiologic characteristics were: female:male [corrected] ratio 1:1.3; peak incidence at 2-4 months age, with 80% before age 6 months; increased incidence during the autumn and winter months (85% of SIDS cases); and highest incidence between midnight and 8:00 AM (84% of SIDS cases). None of the infants had a history of a previous apparent life-threatening event. Birthweight of infants who died of SIDS was not significantly different from that in the general population. No statistical relation to DTP (diphtheria, tetanus, pertussis) vaccination was found. Half the cases had mild respiratory illness during the week that preceded the sudden death. The incidence of parental cigarette smoking was higher than in the general population (56.5% vs. 36-53%; P less than 0.005) as well as the incidence of maternal smoking during pregnancy. We conclude that the incidence of SIDS in Israel is relatively low. The epidemiologic characteristics of SIDS in Israel are very similar to the presentation of the syndrome in other countries.

Abstract
We evaluated the outcome of oncology patients in the Pediatric Intensive Care Unit (PICU) from a total of 72 consecutive admissions. Severity of illness and quantity of care were measured by the Physiologic Stability Index (PSI) and the Therapeutic Intervention Scoring System (TISS), respectively. The overall mortality was 51% and was especially high in patients admitted for acute organ system failure (OSF)-66%. Acute respiratory failure was the most frequent OSF (73%) and the most common cause for PICU admission. A poor outcome was associated with severe leucopenia (less than 1000 WBC/mm3, 91% mortality), acute renal failure (94% mortality) and central nervous system deterioration (83% mortality). When the outcome was predicted using a quantitative algorithm the observed mortality was significantly higher than the predicted for all admissions with a PSI higher than 5. Improved scoring systems are required to enable characterization of pediatric cancer patients admitted to the PICU.

Abstract
The effect of extreme leukocytosis (greater than 300,000/mm3) on the PaO2 of blood stored at 22 degrees and 2 degrees C was studied in two children with leukemia. Arterial blood samples drawn from these patients at 1 and 10 min were compared to blood samples drawn from eight control patients with normal leukocyte counts and PaO2 levels in the same range. One minute after drawing the samples, the PaO2 values at 2 degrees C were significantly higher than those stored at 22 degrees C. Later, there was a rapid and progressive decline in PaO2 values in both samples stored at 2 degrees and 22 degrees C. Rapid consumption of O2 by leukocytes is liable to result in erroneous diagnosis of severe hypoxemia in patients with extreme leukocytosis. Immediate cooling of the samples is insufficient to eliminate this process.

Abstract
Acute hepatic failure (AHF) combined with acute renal failure (ARF) is a well-known complication of open-heart surgery in adults. The occurrence of this complication in two children after open-heart surgery for correction of congenital heart disease is reported. Hypotension occurred during the operation and was treated by catecholamine vasopressors. AHF set in during the postoperative course; it was manifested by impaired consciousness, hypoglycemia, hyperbilirubinemia, hyperammonemia, elevated liver enzymes and prolongation of the prothrombin time with failure of hemostasis. ARF also developed in both children. One of the patients survived the acute episode of hepatic failure. The importance of early diagnosis, routine close monitoring, and appropriate selection of vasopressors is emphasized.

Abstract
The total and differential leukocyte counts of 238 infants with acute gastroenteritis were evaluated as an aid in differentiating between nonbacterial and bacterial infection. In contrast to the total leukocyte count, which was noncontributory, the absolute band count and the ratio between band and total neutrophil count (B/N ratio) were helpful, with the highest values seen in patients with Shigellosis. A B/N ratio greater than 0.10 can help differentiate Shigella, Salmonella, and Campylobacter infections from E. coli and nonbacterial gastroenteritis with a sensitivity of 84.3 per cent and a specificity of 74.5 per cent.

Abstract
A 6-year-old girl had recurrent dyspnoeic attacks during sleep caused by laryngospasm. An abnormal electroencephalogram and an excellent response to carbamazepine suggests the possibility that the laryngospasm was a manifestation of epilepsy.
