RESUMEN
BACKGROUND: Population-based data on pediatric patients on long-term respiratory support (LTRS) in Austria are lacking. This study aimed to record the pediatric departments active in this field, as well as number and characteristics of patients on LTRS. METHODS: A national cross-sectional study was carried out by means of questionnaires sent to all pediatric departments in Austria. RESULTS: All departments answered to the questionnaires. On June 1st, 2013, the reference day for this study, 12 of the 41 pediatric departments in Austria were active in the field. At this time, these centers were caring for 143 patients, 111 (77.6%) of them under 18 years, which corresponds to a prevalence of 7.4 per 100 000. The patients suffered from neuromuscular disorders (44%), other neurological disorders (18.9%), disorders of respiratory drive (9.1%), obstructive sleep apnea (8.4%), thoracal and spinal diseases (8.4%), pulmonary disorders (4.9%) and other diseases (6.3%). Continuous positive airway pressure was used in 6.3%, non-invasive ventilation in 60.1% and invasive ventilation in 33.6% of the patients, respectively. LTRS was performed at home in 92.3%. CONCLUSION: LTRS represents a common management strategy in children and adolescents with a variety of disorders. Census reports such as this one provide the basis for appropriate planning of resource allocation. The age distribution of our patients shows the need for structured transition into adult care.

The COVID-19 pandemic is currently a challenge worldwide. In Austria, a crisis within the health care system has so far been avoided. The treatment of patients with community-acquired pneumonia (CAP), including SARS-CoV2 infections, should continue to be based on evidence-based CAP guidelines during the pandemic. However, COVID-19-specific adjustments are useful. The treatment of patients with chronic lung diseases must be adapted during the pandemic, but must still be guaranteed.
RESUMEN
Infectious diseases of the upper airway can lead to emergency situations with partial up to complete obstruction and respiratory insufficiency, especially in infants and toddlers. This necessitates a cool-headed and calm approach; however, at times a prompt intervention is required by the primary care physician. Important questions concerning patient history include the onset of symptoms, severity and duration of fever and for orientation possible previously known respiratory problems since birth or in the first weeks afterwards (e.g. congenital malformations of the larynx or trachea). The examination should begin by careful observation of the child's position of comfort and by noting all vital signs. A child with inspiratory or biphasic stridor at rest already has some degree of airway obstruction that can progress to complete obstruction over time. Systemic steroids and inhalation of nebulized epinephrine (adrenaline) are the best therapeutic options for viral laryngotracheobronchitis, which is the most common cause of acute stridor in childhood. Rare differential diagnoses, such as bacterial tracheitis, epiglottitis (supraglottitis), retropharyngeal and parapharyngeal infections necessitate disease-specific management.
RESUMEN
BACKGROUND: Lung clearance index (LCI) is increasingly used as a study endpoint for therapeutic interventions in cystic fibrosis (CF) patients. We set out to assess the effect of chest physiotherapy on ventilation inhomogeneity in clinically stable patients with CF lung disease of varying severity. METHODS: In 29 CF patients (7.3-43.7 years) N2MBW (nitrogen multiple breath washout), plethysmography, and spirometry measurements were conducted, followed by 30 min of supervised PEP mask chest physiotherapy and repeated measurements 30 min after therapy. RESULTS: We observed a mean change in LCI after physiotherapy from 15.00 to 14.80 (range, -4.84 to 3.37; p=0.578). In seven patients, LCI decreased, and in ten patients, LCI increased by ≥1. For the whole group, statistically significant improvements were seen in Reff, FEV1, FVC, and MEF50. CONCLUSIONS: By opening up previously poorly ventilated lung regions, physiotherapy may either increase or decrease ventilation inhomogeneity; the short-term effect of physiotherapy on LCI appears to be unpredictable.

BACKGROUND: Serum eosinophil cationic protein (ECP) has been promoted as a marker of inflammatory activity in bronchial asthma. Bronchial responsiveness, measured either by inhaling pharmacologically active substances such as histamine or methacholine, or by applying physical stimuli such as the hyperventilation of cold dry air, is also considered to be an indirect marker of bronchial inflammation. OBJECTIVES: In this study, we investigated the possible relationship between serum ECP and bronchial responsiveness to both cold dry air and histamine in presently symptom- and medication-free pediatric and adolescent asthma patients. SUBJECTS: Thirty-six children and adolescents with atopic asthma were studied. METHODS: On 2 consecutive days, bronchial responsiveness was assessed nonpharmacologically by cold dry air and pharmacologically by histamine in random order. Blood samples for determination of ECP were collected before each challenge. RESULTS: Serum ECP levels correlated with neither cold dry air-induced changes in FEV1 nor the provocation concentrations of histamine causing a 20% fall in FEV1. Subjects with bronchial hyperresponsiveness to cold dry air and histamine had somewhat higher levels of serum ECP than subjects with normal responses, but these differences were insignificant. CONCLUSIONS: Our results indicate a lack of relationship both between serum ECP and bronchial responsiveness to cold dry air and between serum ECP and bronchial responsiveness to histamine.

We report two children who presented with cough and shortness of breath 7-8 months after a matched sibling stem cell transplant (SCT) for chronic myelogenous leukemia and myelodysplastic syndrome, respectively. Pulmonary function tests (PFTs) revealed severe airways obstruction (AO). However, radiographic investigations showed no serious abnormalities in the early phase and open lung biopsy revealed only mild lymphocytic bronchiolitis and bronchiolitis obliterans consistent with pulmonary graft-versus-host disease (GVHD). Despite administration of bronchodilators and various immunosuppressive agents obstructive lung disease progressed to pulmonary failure in patient 1, whereas stabilization of the clinical course was observed in patient 2. Serial PFTs were the best predictor of the clinical course in contrast to radiographic and histologic findings. It is concluded that PFTs should be performed repeatedly in pediatric patients after allogeneic SCT with the aim of diagnosing GVHD-associated AO in the subclinical phase. Progressive post-transplant AO necessitates prompt initiation of intensive immunosuppressive therapy in order to stop the underlying immunopathologic process even in the absence of severe radiographic and histologic findings.

Tracheobronchomegaly (Mounier-Kuhn syndrome) is characterized by dilatation of the central airways, tracheobronchial outpouchings, and chronic tracheobronchitis. Most cases are diagnosed in adulthood. We report the clinical, radiographic, and bronchoscopic findings in a 14-year-old boy with tracheobronchomegaly, ptosis of the right eyelid, and redundant skin and mucosa of the upper lip, who presented with a 2-year history of recurrent lower respiratory tract infections. Pediatricians should be aware of the possibility that tracheobronchomegaly may cause clinical symptoms in childhood and adolescence. Pediatr Pulmonol. 2000; 29: 476-479.

In the years 1980-1984, one paramyxovirus type 4 and 11 influenza viruses were isolated from cloacal swabs collected from migratory waterfowls in Fed. Rep. Germany. One influenza virus of H4N8 subtype was isolated from swabs of commercial ducks collected at an abbatoir. Seven of 10 influenza strains, isolated from mallard ducks and coot were identified as a mixture of 2-3 strains of H1, H4, and H5 subtype; 3 virus strains from the same locality relate antigenically to subtype H4 with enzyme serologically identical with N2--Singapore/57 as demonstrated by means of polyclonal and monoclonal antibody.

Fourteen patients with cystic fibrosis were trained in 2 self-administered chest physiotherapy (PT) techniques: high-pressure PEP-mask physiotherapy (PEP), and autogenic drainage (AD). They then visited the clinic on 5 consecutive days, and, in a random order, performed 1 of the following: PEP, AD, PEP followed by AD (PEP-AD), AD followed by PEP (AD-PEP), and, no PT except for spontaneous coughing. Lung function was measured repeatedly before, during, and after PT; time needed for and sputum produced by each form of PT was recorded. PEP produced the highest amount of sputum, followed by PEP-AD, AD-PEP, and AD; all 4 forms of PT produced significantly more sputum than coughing. Lung function improved significantly after PEP, AD, and PEP-AD, but PEP-induced changes did not exceed those after AD. Within the investigated group, the PEP-induced lung function improvement per milliliter of sputum produced was significantly lower for those patients with airway hyperreactivity. The fact that the highest sputum yield with PEP was not reflected in higher PEP-effected lung function changes might thus be explained by PEP-induced bronchospasm in patients with airway hyperreactivity. PEP clears more sputum than AD or combined techniques; patients with airway hyperreactivity, however, should either prefer AD or should take a bronchodilator premedication before PEP.

This case study reports on two infants, 5 and 6 months of age, respectively, with chronic interstitial lung disease who presented with failure to thrive, tachypnoea, rales and mild hypoxaemia. Epstein-Barr virus (EBV) was detected by in situ hybridization in lung biopsy specimens and by EBV-deoxyribonucleic acid-polymerase chain reaction (PCR) in bronchoalveolar lavage (BAL) fluid in one patient and by in situ hybridization and PCR analysis in BAL fluid in the second patient. There was serological evidence of immunoglobulin G antibodies to EBV capsid antigen by indirect immunofluorescence in both patients. After 7 months of respiratory symptoms one patient was successfully treated with a 10 day course of intravenous ganciclovir followed by oral acyclovir for 20 days. The other patient became symptom free after 3.5 months of respiratory symptoms, without any specific antiviral medication. During a follow-up of 2 and 1.5 yrs, respectively, both infants remained symptom free and showed normal physical development.

Nedocromil and salbutamol are effective drugs in preventing exercise-induced asthma (EIA). The aim of this study was to compare the protective effects of both drugs and a combination of both drugs against cold dry air-induced bronchoconstriction, using cold dry air challenges (CACh) as a surrogate for exercise. Twenty-five atopic children (mean age 13.7, range 8-18 yrs) with EIA participated in the study. Lung function tests were performed before medication, 30 min after medication and just before CACh, and 3 and 15 min after the challenge on four consecutive days. CACh consisted of a 4-min isocapnic hyperpnoea of -10 degrees C, absolutely dry air. Treatment consisted of nedocromil (two puffs of 2 mg) plus placebo, salbutamol (two puffs of 100 microg) plus placebo, the combination of both drugs, and placebo alone, in a random order. Both active drugs were significantly more protective than placebo and the combination showed an additive effect. Mean maximum postchallenge decrease in forced expiratory volume in one second after placebo was 27+/-8.1%, 12+/-9.5% after nedocromil, 8+/-10.4% after salbutamol, and 4.5+/-6.71% after the combination of both drugs, respectively. These results suggest that both drugs protect against exercise-induced asthma. Although not as effective as salbutamol and combined medication, nedocromil can give sufficient protection for many patients.

A 7 year-old Turkish boy presented with a euthyroid goiter, which was noted during evaluation of familial Mediterranean fever. Amyloid deposits in the thyroid were found on fine-needle aspiration biopsy. Slight involution of the goiter within seven months may be attributed either to colchicine therapy or to treatment with levothyroxine and iodide.

UNLABELLED: We report on the clinical, laboratory, and molecular genetic findings in a 15-month-old boy who initially presented with disseminated cytomegalovirus and concomitant para-influenza virus infection. Hyper-IgM syndrome, suspected on clinical grounds, was confirmed by immunological investigations. In addition, a previously unreported potentially disease-causing mutation in the CD40 ligand gene was detected in this patient. CONCLUSION: The present case illustrates that disseminated cytomegalovirus infection with atypical clinical features should be included in the spectrum of the hyper-IgM syndrome.

BACKGROUND: Laser acupuncture, a painless technique, is a widely used alternative treatment method for childhood asthma, although its efficacy has not been proved in controlled clinical studies. METHODS: A double blind, placebo controlled, crossover study was performed to investigate the possible protective effect of a single laser acupuncture treatment on cold dry air hyperventilation induced bronchoconstriction in 44 children and adolescents of mean age 11.9 years (range 7.5-16.7) with exercise induced asthma. Laser acupuncture was performed on real and placebo points in random order on two consecutive days. Lung function was measured before laser acupuncture, immediately after laser acupuncture (just before cold dry air challenge (CACh)), and 3 and 15 minutes after CACh. CACh consisted of a 4 minute isocapnic hyperventilation of -10 degrees C absolute dry air. RESULTS: Comparison of real acupuncture with placebo acupuncture showed no significant differences in the mean maximum CACh induced decrease in forced expiratory volume in 1 second (27.2 (18.2)% v 23.8 (16.2)%) and maximal expiratory flow at 25% remaining vital capacity (51.6 (20.8)% v 44.4 (22.3)%). CONCLUSIONS: A single laser acupuncture treatment offers no protection against exercise induced bronchoconstriction in paediatric and adolescent patients.

UNLABELLED: We report on two Turkish children who presented with progressive airway obstruction. Open lung biopsy revealed follicular bronchiolitis. The children were treated with systemic steroids and various topical medications. Whereas the respiratory situation of patient 1 required immunosuppressive therapy, the condition of patient 2 stabilised without systemic medication. CONCLUSION: Diagnosis of follicular bronchiolitis should be considered when children present with recurrent respiratory tract infections, progressive dyspnoea, and chronic bronchial obstruction. Children in whom follicular bronchiolitis is suspected should undergo open lung biopsy for confirmation of diagnosis.
