Packed pink blood cell or exchange transfusion decreases the fraction of sickle hemoglobin and improves the Table sixty two. In patients with extreme anemia, a "easy" transfusion is used, but if the affected person has a relatively high hematocrit, then change transfusion must be undertaken to avoid growing blood viscosity. Predictors of severity embrace growing hypoxia, growing respiratory price, decreased platelet depend, and multilobar disease. In such patients, noninvasive air flow has been demonstrated to improve oxygenation, however this can be poorly tolerated. Patient managed analgesia devices might cut back the chance of narcotic induced hypoventilation. The most fast deterioration in lung operate occurs in very young children43; thus, annual respiratory monitoring ought to begin early. In addition, the patterns of light absorption differ between HbS and HbA and HbA is used to calibrate oximeters. A systematic review concluded that hydroxyurea is efficient and protected in adults severely affected by sickle cell anemia. An evidence-based report by skilled panel members gave a advice of average energy concerning providing therapy with hydroxyurea without regard to the presence of symptoms for infants, youngsters, and adolescents. It is therefore essential that they bear assessment for bronchial hyperreactivity in accordance with their lung function, and people with airway function less than 70% of predicted ought to receive a bronchodilator and those with better airway operate better than 70% of predicted ought to receive both a cold air or exercise problem.

Endotracheal tube sizes can be too large and sufficient to cause important injury to the larynx if not acknowledged and promptly downsized after arriving at the receiving pediatric institution. Instillation of surfactant has been reported44�46 and is an interesting therapeutic intervention given that nearly all of victims aspirate a amount of fluid that may denature and wash out existing surfactant. In cases of extreme hypothermia, rewarming will be important to allow return of cardiac perform,38,39 and if the core temperature is beneath 26�C�28�C, or the affected person is in cardiac arrest, rewarming might be greatest achieved utilizing cardiopulmonary bypass. While period of submersion, however not water temperature, is reported to be more associated with drowning outcome,56 excellent neurological outcomes have been reported after prolonged immersion in very cold water, with several case reports indicating full neurological recovery after intervals of as a lot as sixty six minutes in near-freezing water. It has been estimated that brain temperature must fall by no less than 3�C throughout the first 5 minutes of immersion for cerebral safety to be effective. However, this trial was comparatively small, and the hypothermia group was additionally managed with hyperventilation and high-dose phenobarbitone, which may have influenced the outcomes. A randomized, managed trial of therapeutic hypothermia versus normothermia after cardiac arrest exterior of the hospital has been undertaken by 38 pediatric centers within the United States and Canada under the auspices of the National Institutes of Health. This research showed no benefit of hypothermia over rigorously managed normothermia in either mortality or neurodevelopmentally in the 1-year follow-up of 295 survivors. Seven had irregular methacholine challenges demonstrating a excessive incidence of bronchial hyperreactivity, and five had clear evidence of peripheral airways illness. Poor outcomes are noticed in 60%�100% of subjects immersed for higher than 10 minutes, compared to 0%�30% of these immersed for five minutes. It is troublesome to present early and accurate prognostic data on comatose children, especially if brainstem functions are intact.

For most infants, the periodic breathing runs were brief and benign, although falls in SpO2% and cerebral tissue oxygenation index were typically statistically important. Three infants had massive and sustained falls in coronary heart rate, SpO2% (to <80%), and cerebral oxygenation index. Apneic pauses longer than 5 seconds are common on the first day of life among premature infants without respiratory distress syndrome and might increase to 25 per day by the third day. In the examine by Eichenwald and coworkers,35 apnea was diagnosed when chest wall motion was not detected by impedance monitoring. The last occasions to disappear with maturation have been bradycardia episodes with out related central apnea. Another study utilizing transthoracic impedance but incorporating motionartifact resistant oximetry has led to similarly believable hypothesis. The majority (75%) of preterm births in the United States annually are on this group, and over four hundred,000 infants are born at 33�37 weeks yearly. But issues are growing about respiratory morbidity and about 80 � Sudden Infant Death Syndrome and Apparent Life-Threatening Events 1133 neurodevelopmental milestones in late preterms, particularly almost about mathematics and reading expertise. Esophageal strain tracing, with cardiogenic artifact, demonstrates first central apnea, then respiratory efforts. Flow and volume tracings present that the first four or five efforts after central apnea are obstructed. However, it has just lately been proven that infants have more apnea when their hematocrit is lower, and apnea is much less frequent for three days after a transfusion. Pulmonologists should pay consideration to the policies of local pediatric anesthesiologists with respect to perioperative monitoring, even for semielective surgical procedure such as herniorrhaphy. Monitoring for apnea in preterm infants must continue to be part of this dialogue. This elementary insight led to much analysis into reflexes, ventilatory control, and brainstem neurochemistry to make clear what was outlined as "unexplained" by typical histopathology. Death results from one or more failures in protective mechanisms against a life-threatening event during sleep within the vulnerable infant during a important period. In particular, infants unaccustomed to prone sleep are at an 18-fold increased danger for sudden demise when placed inclined. It emphasizes the chance that almost all deaths have a quantity of partial explanations, within a causal sequence. A perspective on neuropathologic findings in victims of the sudden infant dying syndrome. In a given toddler or group of infants the relative importance of each affect may vary. Investigations into sleep practices over the past 20 years have elevated the understanding of exogenous stressors. Moreover, amelioration of a number of of the danger components present on this example would scale back the risk for dying. The success of supine sleep interventions in many countries suggests that the susceptible place is critical at a quantity of junctures in a hypothetical causal sequence, at least amongst infants sleeping alone. Deaths from unintended suffocation and strangulation in bed rose from ~0 in 1990 to ~0. It summarized the epidemiologic and physiologic analysis supporting an interaction between sleep place and a sleep setting containing free blankets and soft sleep surfaces leading to rebreathing that can be lethal and to thermal stress. Three latest important papers tackle newer points pertinent to the apparent however generally complicated decline in surprising toddler deaths within the Nineties and early on this century. Among reductions they cite are much less smoking throughout being pregnant and fewer moms by no means breastfeeding. The % of infants being put to sleep in the back sleeping place elevated from roughly 15% in 1998 to approximately 72% in 2010. However, as the authors claim, they want to quantify how regularly this occurs and recognize ". This means that the developmental processes resulting in vulnerability occurred earlier in preterm infants. Thus, generally, when infants die all of a sudden and unexpectedly, perhaps 1 in 6 of the deaths will be defined by postmortem findings or checks carried out on autopsy specimens. Over half (58%) have been explained by post-mortem, primarily by congenital heart disease, acute infections, and fatty acid oxidation deficiencies. The mannequin outlined130 could also be particularly related to elevated danger for dying linked to nicotine exposure.

After taking an in depth environmental history, skin testing ought to be carried out (usually percutaneous or scratch), limited to the more than likely allergens, as suggested by the historical past. Drugs that affect skin take a look at results embody H1 antihistamines (which might inhibit skin reactions for as much as seventy two hours or longer), tricyclic antidepressants, and a few histamine (H2) blockers. Positive (histamine) and adverse (saline) management checks should be included to detect inherent pores and skin components that will affect the response to allergen, such as dermatographism and in depth dryness or eczema. The in vitro measure of allergen-specific IgE (s-IgE) makes use of the affinity of serum IgE antibody for antigen that has been bound to a solid section substrate. The s-IgE test is considerably more expensive than skin testing, but it can be carried out in commercial laboratories and is useful for situations in which pores and skin checks are impractical. Associated indicators and symptoms that should prompt a sweat take a look at embrace poor weight acquire and short stature, steatorrhea, nasal polyps, pansinusitis, hemoptysis, and digital clubbing. Newborn screening for cystic fibrosis is now universal in the United States, and most circumstances of cystic fibrosis are identified in infancy or the preschool years, but screening does have a false negative rate of roughly 5%, depending on the cutoff values and the methods chosen. Mutations conferring pancreatic sufficiency, and different uncommon mutations are usually associated with milder pulmonary illness and should present a lot later than infancy (see Chapter 50). A chest radiograph must be thought of for the kid admitted to a hospital with bronchial asthma, significantly if there are localized findings on physical examination. Paranasal sinus radiographs or screening sinus computed tomography can also be considered for youngsters with persistent nocturnal coughing, nasal signs, and headaches. Nasal symptoms did enhance, however the examine results argue against treating nasal signs to enhance bronchial asthma control. As a result, severity turns into outlined by the level of treatment essential to obtain and maintain enough control. Identifying kids and adolescents with severe or therapy resistant bronchial asthma is important as a result of the necessity for shut monitoring and aggressive remedy shall be significant. For most other sufferers, correct evaluation of control is more important than severity assignment to have the ability to adequately manage bronchial asthma. Asthma management is divided into two parts: impairment or symptom control and risk. The danger area refers to stopping severe exacerbations that require medical consideration, similar to prescription of systemic steroids, emergency medical remedy or hospitalization, lack of lung operate or impairment of regular lung development, and opposed effects brought on by treatment use. This strategy draws consideration to the management of present symptoms and functional impairment, as nicely as the lengthy run results of asthma and its remedy on lung perform and severe exacerbations. It additionally highlights the essential observation that bronchial asthma therapy methods that enhance symptoms may not always outcome within the prevention of significant exacerbations. Asthma is finest managed in a steady trend by forming a partnership with a knowledgeable physician or different well being care supplier. The concept of anticipating a close to symptom-free way of life (for all but the most severely affected patients) must be instilled in sufferers and their families. Participation in recreational activities, sports activities, and college attendance ought to all be expected. Parents should perceive that asthma is a chronic disease with acute exacerbations that with presently obtainable remedies may be controlled, but not cured. As higher characterization of the inflammatory processes and pathways that affect the airway in specific sufferers and development of real-time noninvasive monitoring strategies occurs, more precise management of bronchial asthma signs and even main or secondary illness prevention could become a sensible objective of asthma management. Classification of Asthma Over the past decade, increasing consciousness has been targeted on the broad heterogeneity of bronchial asthma, both with respect to its causes, manifestations, and response to treatment. Age of onset of symptoms, lung operate, inflammatory cell sorts and mediators in induced sputum, and atopic versus nonatopic are all markers used to characterize illness severity, symptom pattern, and response to treatment. Considerable analysis remains to be wanted to precisely identify bronchial asthma phenotypes and to determine clinically helpful strategies for classification. In addition, the number, frequency, and intensity of extreme exacerbations-defined as a rise in signs sufficient to warrant therapy with oral corticosteroids or therapy within the emergency department or inpatient hospital unit-are considered. Although the correlation between the quantity and depth of exacerbations with severity ranges is less clear, the higher the number and severity. However, the diploma of severity of asthma usually changes in a given individual with time, response to therapy, airway harm or progress, the development of newly acquired allergic sensitivities, or change in publicity to recognized triggers. As a result, willpower of management after remedy has been instituted is of larger significance than assigning a severity stage. Using very comparable criteria, bronchial asthma is decided to be nicely managed, not nicely managed, or very poorly managed (Table forty five.

The lesson right here is that early discussion with the safeguarding staff is crucial if there are any concerns, and that no pediatric referral heart for severe asthma can operate with out entry to a extremely good safeguarding service. Increasingly Important within the Assessment Process: A Hospital Admission We find that an admission to hospital for evaluation over 2 weeks is effective when signs are thought to be overreported. As far as potential, regular activities, including attending the hospital faculty and collaborating in physical exercise, should proceed. This is intended as a possibility to regulate and hopefully scale back some asthma drugs. Admission plan To remain resident on the ward during the period of the admission and solely depart the ward for brief durations with the permission of ward employees or longer trip supervised by a nurse Attend college on faculty days. The Difficult Asthma Team will liaise carefully with the attending medical team all through the admission Urine cotinine on admission Prednisolone stage and random cortisol on the day of admission for all kids prescribed prednisolone. Severe, Therapy-Resistant Asthma: Deconstructing the Airway Disease If extrapulmonary and environmental/lifestyle have been excluded, consideration switches to the nature of the underlying airway illness. Likewise, a cough is a secondary phenomenon, and the treatment is of the underlying cause. There are numerous differences between the typical severe, therapy-resistant asthmatic baby and the image in adults. In our sequence, there was no female predominance; a robust atopic history was frequent (85% atopic with a complete median IgE of 386 [range: 115-1286]). In both adults and youngsters, asthma-related high quality of life was considerably worse within the severe groups. Difficult Asthma: Summary this assessment course of generates an enormous amount of detailed data, and this is reviewed in a devoted, multidisciplinary group assembly, the place we try to place the child in one of two categories: (1) tough bronchial asthma, in which comorbidities and environmental/lifestyle factors are liable for the poor response to therapy; and (2) severe, therapyresistant asthma, by which atypical airway disease is the purpose for the issue. The key requirement for the protected efficiency of bronchoscopy in these children is a skilled anesthesiologist. Is there phenotype discordance, specifically a disconnect between signs and eosinophilic airway inflammation Is the kid partially or totally steroid responsive, or steroid resistant, in accordance with our multidimensional framework We saw an acute extreme bronchospasm on one occasion, which quickly responded to treatment. Interestingly, intraepithelial neutrophils are associated with better markers of asthma control, which underscores that possibly some forms of irritation may be beneficial. A neutrophilic submucosa should immediate reconsideration of the analysis of asthma. However, as an growing array of monoclonal antibodies are coming on the market, we want to move from cell-based descriptions to pathway based mostly, if these expensive resources are to be focused properly. What it does mean is that the elements driving ongoing extreme illness are different, and are, as but, unknown. Further work is clearly wanted so as to delineate the proinflammatory mechanisms driving pediatric extreme, therapy-resistant asthma. It could also be justified to carry out a therapeutic n of 1 trial in a toddler doing badly on all therapies. Some children who were nonresponsive utilizing the grownup definition were partial responders in the multidomain evaluation. Assessment of corticosteroid response in pediatric sufferers with severe bronchial asthma by utilizing a multidomain method. Treatment of Severe, Therapy-Resistant Asthma the remedy choices, with the exception of using omalizumab, are largely anecdote primarily based. Although guidelines mandate aeroallergen sensitization, omalizumab may be trialed within the rare nonatopic baby with IgE within the range where omalizumab is indicated. Steroid-responsive irritation may predict an excellent response to omalizumab (above). However, a small minority of asthmatic youngsters may profit from growing the dose as high as 2000 �g/day. If that is on the worth of unacceptable side effects, then a steroid-sparing agent (see later) ought to be thought-about. We also consider its use within the youngster with symptoms and ongoing peak flow variability, however with out evidence of eosinophilic airway irritation.

Physical examination reveals tachypnea, diffuse crackles, cyanosis, and infrequently skin eruptions. Hypoxemia is observed in 90%�95% of sufferers, and mild eosinophilia has been reported in 41%. Pulmonary infection must be excluded, notably if high-dose methotrexate is used or if the underlying illness is related to immunosuppression. Therapy consists of withdrawal of the drug and administration of corticosteroids, but the latter has not been analyzed in managed trials. Gemcitabine has also been related to dyspnea, bronchoconstriction, and nonspecific pneumonitis, significantly in Hodgkin disease sufferers also treated with bleomycin. Hydroxyurea has been reported to induce severe, corticosteroid-responsive, hypersensitivity pneumonitis. In addition, an post-mortem study of sufferers who had leukemia and who received cytosine arabinoside within 30 days of dying demonstrated significant pulmonary edema for which there was no apparent different explanation in most instances. In an irradiated rat mannequin, gefitinib therapy augmented lung inflammation but attenuated fibrotic lung 59 � Lung Injury Caused by Pharmacologic Agents 881 transforming due to the inhibition of lung fibroblast proliferation. Another tyrosine kinase inhibitor, imatinib, is used in therapy of continual myelogenous leukemia and has been related to pleural effusion and pulmonary edema in a small variety of cases. In a collection of 2006 patients with colorectal most cancers in a potential multicenter registry, ranging in age from 18 to 80 years, 1. Although a number of systemic unwanted side effects such as fever and hypotension are seen, its major toxicity appears to be a vascular leak syndrome characterized by fluid retention, peripheral edema, ascites, pleural effusion, and pulmonary edema. Its major toxicity is a syndrome together with fever, weight gain and peripheral edema, respiratory distress, interstitial infiltrates, pleural and pericardial effusions, hyperleukocytosis, intermittent hypotension, and acute renal failure. Mean length of therapy earlier than the syndrome appeared was eleven days with a variety of 2�47 days. Significant pulmonary reactions are comparatively widespread, and more than 500 circumstances have been reported, together with children (see Table fifty nine. In the more frequent acute presentation, sufferers report abrupt onset of fever, cough, and dyspnea within hours to 2 weeks after initiation of therapy. Bilateral interstitial or alveolar infiltrates with or with out pleural effusions are characteristically current, though chest radiographs could additionally be normal. Eosinophilia, leukocytosis, and an elevated sedimentation price could accompany the response. Symptoms and chest radiographic abnormalities often resolve within several days after withdrawal of the drug. Pulmonary histopathology of the acute syndrome has not been properly defined, as sufferers improve rapidly, making biopsy pointless. In the much less common chronic presentation, patients develop insidious onset of cough, dyspnea, and chest ache after months to years of nitrofurantoin therapy. Physiologic abnormalities are similar to these discovered within the acute response but are often more severe. Eosinophilia, constructive reactions for antinuclear antibodies, and elevated gamma globulin and hepatic enzymes are sometimes discovered, and important concurrent hepatic toxicity has been reported. Resolution of symptoms, physiologic dysfunction, and radiographic abnormalities require weeks to months and could additionally be incomplete. The findings of eosinophilia, elevation of sedimentation rate, and constructive antinuclear antibodies help a role for immunologic mechanisms of damage. Adverse reactions occur in roughly 20% of recipients, but pulmonary reactions are unusual; 50 circumstances had been recognized in the most complete review. Hypoxemia, eosinophilia, obstructive and infrequently restrictive pulmonary operate patterns, and bilateral alveolar densities have been famous. Histopathologic lesions embody interstitial pneumonitis with or with out fibrosis, eosinophilic pneumonia, fibrosing alveolitis, and bronchiolitis obliterans with or with no part of organizing pneumonia. Discontinuation of the drug usually results in decision of signs and radiographic abnormalities in a quantity of weeks to months.

Lastly, if no mutations are found, next-generation sequencing approaches, similar to complete exome sequencing, are wanted to complete the genetic testing. Finally, in the exceptional cases the place genetic testing is negative, dystrophin protein evaluation may be necessary to make the analysis from muscle biopsy. Electromyography reveals denervation and diminished motor motion potential amplitude. Delineation of the type of scoliosis and the vertebrae and ribs concerned requires imaging, initially with an anterior-posterior and lateral view of the whole spine. Functional severity of kyphoscoliosis ought to be performed in concert with the structural assessment. Hypoplastic Thorax Syndromes Hypoplastic thoraces may be apparent or delicate at birth. Recently, gender-specific correlations between pelvic dimensions, spine peak, and chest wall dimensions have been made, and norms have been revealed. An enough O2 supply and the correction of electrolytic imbalance (hypophosphatemia, hypocalcemia, hypokalemia, acidosis) are additionally wanted for muscles to perform their work. Associated nonrelated respiratory issues, similar to asthma, allergic rhinitis, enlarged adenoids, and tonsils causing sleep-disordered respiratory, must be carefully investigated and treated. Prevention of respiratory infections should be applied by making certain an optimal setting. The every day use of assisted cough with lung recruitment methods, both manually or by way of the utilization of an insufflation-exsufflation system, is of paramount significance within the management of sufferers with extreme neuromuscular issues, especially during respiratory infections. In addition, ventilatory support has become a vital software for growing quality of life and prolonging life in severely affected sufferers with neuromuscular issues by resting weakened respiratory muscular tissues. Current consensus suggests that noninvasive nocturnal ventilatory support is indicated for patients with alveolar hypoventilation,36 and must be discussed in the presence of failure to thrive or recurrent chest infections (more than three per year). In addition, nocturnal ventilatory assist could be indicated in the presence of obstructive sleep-disordered respiration. Treatment for symptomatic cases first consists of ventilatory support, when needed. Surgical plication is usually indicated in the presence of persistent or recurrent respiratory symptoms, and is more usually needed in infants than in older children. The optimal timing for surgery within the neonate or baby with diaphragmatic paralysis is controversial. Waiting for spontaneous recovery in symptomatic patients could be associated with important morbidity, particularly in high-risk patients on ventilatory help. Recommendations for such patients vary from quick repair to ready 2�4 weeks for indicators of spontaneous restoration. The use of video-assisted thoracoscopic surgical procedure for diaphragm plication decreases the morbidity related to traditional open thoracotomy. Note the symmetrically fused ribs at the costo-vertebral angle, producing the attribute "fan" or "crab" appearance. Respiratory muscle training is clearly beneficial in specific circumstances the place respiratory muscle tissue are intact, corresponding to in quadriplegic patients, following spinal cord injury. Any therapeutic intervention should goal at rising the quality of life of the kid and have to be preceded by info to the family on both the burden of treatment and the grim prognosis. Infants treated by noninvasive ventilation have been shown to survive longer (over half had been alive at four years of age), albeit on the expense of hospitalizations and a burden of respiratory care that increases with time. Importantly, a written care plan must be decided in advance with the dad and mom with regard to resuscitation and intubation/ventilation in case of a reversible acute occasion, similar to a respiratory infection. However, enchancment with such medication is normally incomplete and most patients require further therapeutic measures, similar to prednisone and consideration of thymectomy. During acute exacerbations of the disease, or in the center of respiratory complications, respiratory assist may be required for numerous lengths of time (a few days to several weeks), in association with short-term immunotherapy, including intravenous immunoglobulins and plasmapheresis. Neonatal Myasthenia Gravis Management relies on pyridostigmine as properly as adequate feeding and respiratory support until spontaneous remittance of muscle weak spot happens. Importantly, salbutamol or ephedrine, alone or combined with other medication, is increasingly reported as beneficial for so much of subtypes of congenital myasthenic syndromes. In the primary decade, prevention of respiratory infections, enterprise common submaximal exercise, and the remedy of any associated respiratory problems. Loss of ambulation coincides with the onset of progressively growing respiratory issues.

Similarly, the discovering of pepsin in tracheal aspirates of older intubated youngsters (whether fed by nasogastric or nasojejunal tube) could signify that pepsin is in all probability not a clinically helpful biomarker of aspiration, or that reflux aspiration is omnipresent in most intubated infants and children, regardless of feeding status, after a few days. The relationship between airway pepsin and reflux indices is at finest unclear, highlighting the idea that reflux episodes characterize opportunities to aspirate quite than providing direct evidence of aspiration. The relationship between lung illness and airway pepsin has been less studied, other than for lung transplant rejection, the place a relationship has been documented. Fundoplication is the most commonly utilized surgical procedure and is commonly profitable in resolving reflux, and in some studies demonstrates efficacy in reducing respiratory symptoms attributed to reflux. Jejunostomy feedings might permit sufficient feeding and decrease respiratory signs caused by aspiration with out the issues for gasoline bloat or retching; however, there are other points. In a baby with an existing gastrostomy, a trial of conversion to a gastrostomyjejunostomy tube may check the potential impression of an antireflux procedure on respiratory signs which might be suspected to be brought on by reflux aspiration. Oral anticholinergic drugs lower salivation; subsequently they may lower the amount of saliva obtainable to aspirate. These embody behavioral modifications, constipation, dry mouth, urinary retention, flushing, nasal congestion, vomiting, and diarrhea. For this cause, they need to be used with great warning in infants, in youngsters with neuromuscular diseases, and in these with small tracheostomy tubes. Production of saliva could be specifically decreased either by the injection of salivary glands with botulinum toxin, the ligation of salivary ducts, or the elimination of salivary glands. Botulinum toxin injection, duct ligation, and gland excision have all demonstrated efficacy in reduction of drooling and reducing respiratory infections. Aspiration of Oral Secretions Chronic aspiration of saliva is the least-commonly recognized type of aspiration and is probably not recognized until significant lung damage has developed. The oral cavity accommodates a excessive density of micro organism and yeast that may cause lung infections if aspirated in adequate amount. It is unusual for a child without severe swallowing dysfunction to aspirate oral secretions. Children with cricopharyngeal achalasia, severe esophageal dysmotility, stricture, or diverticulum are exceptions. These kids could pool saliva excessively of their hypopharynx and aspirate at evening due to a mix of depressed protective reflexes throughout sleep and the absence of gravity help within the drainage of secretions from the esophagus into the stomach. Evaluation of Lung Injury Caused by Aspiration In those individuals with recognized abnormalities in swallowing perform adequate to trigger lung injury, the extent of the lung injury from aspiration should be sought. Chest radiographs are readily available and are often abnormal in children with persistent aspiration. Hyperaeration, segmental or subsegmental infiltrates, and peribronchial thickening could also be seen-usually in multiple lobes and in a dependent distribution. However, the findings on plain chest radiograph are very nonspecific and are of little use in differentiating chronic aspiration from different diffuse lung diseases. The lack of a compensatory cough or laryngeal adductor reflex additional supports the probability that vital pathologic aspiration of saliva is going on. The presence of activity in the trachea or bronchi signifies aspiration of saliva. While the idea of the check is similar because the radionuclide salivagram, repeated administration captures an extended window of time and will enhance sensitivity. Chest high-resolution computed tomography shows dependent bronchiectasis, consolidations, and centrilobular opacities in a child with persistent aspiration caused by recurrent tracheoesophageal fistula.
