Dexamethasone regime and clinical outcomes in children hospitalized with croup: A cohort study.

High-quality trial evidence supports the use of one dose of dexamethasone in the outpatient management of croup; however, there are no inpatient trials, and the optimal treatment regimen for the inpatient management of croup remains uncertain. Significant practice variability exists in the corticosteroid treatment of children hospitalized for croup. To evaluate the association of dexamethasone treatment regimen (1 vs. >1 dose) with hospital length of stay (LOS) and 30-day return to emergency department (ED) visits among children hospitalized for croup. A cohort study of children hospitalized for croup at a children's hospital between 2010 and 2022. Children less than 10 years old, without known airway anomalies and who received dexamethasone for croup treatment were included. Children who received 1 dose versus >1 dose of dexamethasone were compared. Propensity score analyses, using inverse probability of treatment weighting, were conducted to estimate the treatment effects of dexamethasone regimen on hospital LOS and all-cause 30-day return to ED visit. Of 471 children hospitalized for croup, 229 (49%) received 1 dose of dexamethasone; 242 (51%) received >1 dose. In the propensity-weighted analyses, children receiving >1 dose of dexamethasone had a longer mean LOS by 59.6 h (95% CI 44.8-74.5, p < .001) compared with those receiving >1 dose. There was no statistically significant difference in the odds of all-cause 30-day return to ED visit; OR 1.30, (95% CI 0.76-2.22, p = .33). Among children hospitalized for croup, children who received >1 dose of dexamethasone had a longer LOS compared with children who received 1 dose of dexamethasone; however, there was no statistically significant difference in the 30-day return to ED visits. Randomized clinical trials are needed to determine the optimal dexamethasone treatment regimen for children hospitalized with croup.

Choanal atresia: a review of contemporary treatment strategies.

Choanal atresia (CA) is a congenital nasal airway anomaly that, when present bilaterally, requires urgent surgical intervention. Surgical technique has evolved since its inception with most practices now favoring an endoscopic repair. Restenosis requiring revision surgery is a frequent complication, occurring in as many as 50% of cases. This review aims to highlight the most common surgical approaches, techniques used to prevent restenosis, and newer adjuncts to surgery that may improve outcomes. Bioabsorbable, steroid-eluting stents were first developed for the adult chronic rhinosinusitis population but have been adapted for use in choanal atresia since 2017. The existing literature consists of multiple case series and one case-control study comparing these stents to traditional stents. To date, there have been no reports of restenosis or stent-related complications with these newer products. Choanal atresia remains a difficult surgical pathology for which sustainable surgical results can be challenging. There is reason for optimism in bioabsorbable, steroid-eluting stents as an adjunct to CA repair if future studies expound upon their safety and efficacy.

Congenital airway anomalies and syndromes associated in newborns with esophageal atresia

ObjectiveThis study aims to define the associated comorbidities, syndromes and anatomic findings in newborns with esophageal atresia using bronchoscopy. MethodRetrospective analysis of the database was performed on patients that underwent surgery with esophageal atresia or tracheoesophageal fistula diagnosis between 2016 and 2023 in Dr. Luis Calvo Mackenna Children´s Hospital in whom an airway study was done with rigid laryngotracheoscopy. Demographic data, comorbidities and airway anomalies were registered. ResultsData from 37 patients was analyzed. Comorbidities were present in 62.1 % of the patients. Airway anomalies such as tracheomalacia, laryngomalacia, tracheal diverticulum, congenital tracheal stenosis and cleft were present in 56.75 % of the patients. 72.9 % of the patients had Type C EA and in 32.4 % of the cases tracheoesophageal fistula was located at the carina. ConclusionIn the last 7 years we have done an airway study in 82.2 % of newborns with esophageal atresia. There is a high percentage of patients with airway anomalies, therefore we consider the importance of performing an endoscopic airway study in all patients with EA.

The role of flexible bronchoscope in the evaluation of chronic cough with and without wheeze in children

BackgroundChronic cough in children is a challenging symptom for clinicians. So, we aimed in this study to evaluate the diagnostic role of flexible bronchoscope in differentiating between the underlying causes of chronic wet cough and chronic cough associated with wheeze.MethodsThis was a prospective cross-sectional study conducted on children referred to Tanta University Hospitals and Ain-Shams University Hospitals between January 2021 and January 2023, presenting with a primary complaint of chronic cough lasting more than 4 weeks. The children were further classified into two groups: the first group included children with chronic wet cough not associated with wheezing (Cohort A) and the second group included children with chronic cough associated with wheezing (Cohort B).ResultsThe study enrolled 64 children. During clinical evaluation, 25 (39.1%) children had a chronic cough without wheezing and 39 (60.9%) had a chronic wheezy cough. Bronchoscopic examination findings indicated a notable disparity between the two groups of patients with chronic cough (p=0.006). Among Cohort A patients, the most prevalent bronchoscopic observation was purulent inflammatory secretions in 16 cases (64.0%), followed by congenital airway anomalies in 3 cases (12.0%). Conversely, Cohort B patients exhibited congenital airway anomalies as the primary finding in 14 cases (35.9%), followed by purulent secretions in 7 cases (17.9%).ConclusionFlexible bronchoscopy is a valuable and safe tool for diagnosing chronic cough in children. It helped differentiate between the underlying causes of chronic cough in children with and without wheezing.

Airway Anomalies in Pediatric Patients After Surgery for Congenital Heart Disease: Single-Center Retrospective Cohort Study, Taiwan, 2017-2020.

Airway anomalies increase risk of morbidity and mortality in postoperative pediatric patients with congenital heart disease (CHD). We aimed to identify airway anomalies and the association with intermediate outcomes in patients undergoing surgery for CHD. Single-center, hospital-based retrospective study in Taiwan, 2017-2020. A tertiary referral hospital in Taiwan. All pediatric patients who underwent surgery for CHD and were admitted to the PICU and had data about airway evaluation by cardiopulmonary CT scan or bronchoscopy. None. Among 820 CHD patients identified as having undergone airway evaluation in the PICU, 185 (22.6%) were diagnosed with airway anomalies, including structural lesions in 146 of 185 (78.9%), and dynamic problems were seen in 87 of 185 (47.0%). In this population, the explanatory factors associated with greater odds (odds ratio [OR]) of airway anomaly were premature birth (OR, 1.90; p = 0.002), genetic syndromes (OR, 2.60; p < 0.001), and in those with preoperative ventilator use (OR, 4.28; p < 0.001). In comparison to those without airway anomalies, the presence of airway anomalies was associated with higher hospital mortality (11.4% vs. 2.7%; p < 0.001), prolonged intubation days (8 d [1-27 d] vs. 1 d [1-5 d]; p < 0.001), longer PICU length of stay (23 d [8-81 d] vs. 7 d [4-18 d]; p < 0.001), and greater hazard of intermediate mortality (adjusted hazard ratio, 2.60; p = 0.001). In our single-center retrospective study, 2017-2020, between one-in-five and one-in-four of our postoperative CHD patients undergoing an airway evaluation had airway anomalies. Factors associated with greater odds of airway anomaly included, those with premature birth, or genetic syndromes, and preoperative ventilator use. Overall, in patients undergoing airway evaluation, the finding of an airway anomalies was associated with longer postoperative intubation duration and greater hazard of intermediate mortality.

Neonatal autopsy-is it relevant in today's era?

Autopsy of infants can provide vital information about the cause of death and contributes to the detection of diagnostic errors, especially in a low- or middle-income country. To observe the clinicopathological agreement in neonatal deaths in neonatal intensive care units (NICU) and comment on the additional information retrieved by autopsy. A retrospective observational study was conducted in the NICU from January 2020 to December 2022. Neonatal deaths were analyzed, and clinical details and autopsy findings were collected. Both clinical and pathological diagnoses were classified according to the Goldman classification. Twenty-two newborn infants were enrolled. The mean gestational age was 33.5 (±4.38) weeks, and the median birth weight was 1510 (1005-2100) g. There was complete concordance between clinical and pathological diagnosis in 11 (50%) cases. Major diagnostic errors occurred in 41% of cases. Respiratory system disorders (lung infections, airway anomalies) accounted for six (54%) cases of missed diagnosis. Our study showed that the diagnosis was revised after autopsy in about one-third of cases, and newer findings were identified in one-fifth of cases.

High comorbidity rates in congenital lobar emphysema and the effect on clinical presentation.

The presence of comorbidities (CM) in congenital lobar emphysema (CLE) has been previously described with varying rates. However, the clinical implication of CM on the clinical presentation and patient outcome in CLE is unclear. This was a retrospective cohort study between 2000 and 2022 in a single institution. The study included pediatric patients diagnosed with CLE. During the study period, 36 patients were identified with CLE. The presence of respiratory symptoms at diagnosis was documented in 69% (24/35) of the patients with 48% admitted to intensive care units. The presence of CM was documented in 14/36 (39%) of the patients, with cardiovascular anomalies as the most common (22%), followed by genitourinary anomalies (11%) and large airway anomalies (8%). When comparing the CM group (n = 14) vs the non-CM group (N = 22), there was no significant difference regarding gender, term birth, age of diagnosis, and the location of the lesion. The CM group had significantly higher rates of intensive care unit (ICU) admissions (75% vs 33%, p = 0.02), longer duration of admission (median 46days vs 9, p = 0.02), and need for pre-operative non-invasive respiratory support (50% vs 5%, p = 0.002).Conclusion: The presence of CM in CLE was associated with a more severe presentation as reflected with significantly higher rates of ICU admissions, prolonged admissions, and higher need for non-invasive respiratory support. Screening for CM, mostly for cardiac anomalies, is recommended at time of CLE diagnosis. What is Known: • Congenital lobar emphysema (CLE) is a developmental lung anomaly generally associated with other comorbidities; however, their clinical implication on presentation is unclear • The prevalence of comorbidities in CLE was previously reported around 15-20%, with cardiovascular anomalies as the most common What is New: • Comorbidities are very common (39%) in CLE, and their presence is related to a more severe clinical presentation and need for respiratory support • Screening for comorbidities is recommended in CLE, specifically for cardiovascular and genitourinary anomalies.

Screening of Palatopharyngeal Incoordination in Mechanically Ventilated Critically Ill Infants

Abstract Background Palatopharyngeal incoordination is a common phenomenon in patients requiring endotracheal intubation for mechanical ventilation. Understanding the underlying mechanism of palatopharyngeal incoordination may help as a screening tool that improves rates of early recognition and diagnosis and the ability to take preventive measures essential to alleviate related morbidity and complications. Objective The aim of this study is to screen palatopharyngeal incoordination in infants who needed mechanical ventilation and to elicit palatopharyngeal incoordination secondary to mechanical ventilation. Material and Methods This study included 51 patients at the Pediatric Intensive Care Unit, Faculty of Medicine, Ain Shams University, The study was conducted during the period from February 2021 to February 2022. patients were classified according to a Fiberoptic Flexible Endoscopic Evaluation of Swallowing (FEES) early post intubation, FEES early post extubation, Videofluoroscopic Swallow Study (VFSS) post extubation and dye study into five groups: group (1) the not affected group, group (2) the palatopharyngeal incoordination group, group (3) The palatopharyngeal incoordination with gastro esophageal reflux group, group (4) The reflux group, group (5) The congenital upper air way anomalies group in which patients were ventilated due to respiratory distress. Follow up FEES and VFSS were done after three months for palatopharyngeal incoordination patients. Results Palatopharyngeal incoordination was detected in 16 patients (31.3%), congenital upper airway anomalies were found in 12 patients (23.5%), and gastroesophageal reflux was only detected in 10 patients (19.6%). Performing VFSS and FEES after three months showed 92.3 % of palatopharyngeal incoordination patients had resolved palatopharyngeal incoordination and 7.7 % of palatopharyngeal incoordination patients had silent aspiration. Conclusion The prevalence of palatopharyngeal incoordination is 31.3 % and there was no palatopharyngeal incoordination secondary to mechanical ventilation.

Tracheostomy and inpatient outcomes among children with congenital central hypoventilation syndrome: A kids' inpatient database study.

Congenital central hypoventilation syndrome (CCHS) is a rare disease predisposing children to respiratory failure due to abnormal ventilatory drive. Variability in hypoventilation and respiratory support need have been reported. We aim to identify clinical variables associated with incident tracheostomy and common etiologies of hospitalization among children with CCHS. Hospital discharge records were obtained for children (<21 years) with CCHS hospitalized between 2006 and 2019 from the Kid's Inpatient Database. Primary diagnostic categories for hospitalizations with CCHS were summarized. Multivariable logistic regression models were used to explore risk factors associated with incident tracheostomy. Among 2404 hospitalizations with CCHS, 133 (5.5%) had incident tracheostomy, 1230 (51.2%) had established tracheostomy, and 1041 (43.3%) had no tracheostomy. Compared with children without tracheostomy, those with incident tracheostomy were younger, had a history of prematurity, congenital heart disease, laryngeal, glottic, and subglottic stenosis (LGSS), congenital airway anomalies, neuromuscular weakness, gastroesophageal reflux disease. Children without tracheostomy had higher mortality than those with tracheostomy status (2.19% vs. 0.66%). Multivariable-adjusted analyses showed that incident tracheostomy was associated with infancy (0-1 years), neuromuscular weakness, and congenital heart disease. Most common diagnostic categories include (1) diseases of the respiratory system (30.23%), (2) injury and poisoning (9.35%), and (3) diseases of the nervous system and sense organs (6.71%). Children with CCHS who received incident tracheostomy are more likely to be younger and with LGSS, neuromuscular weakness and congenital heart disease. Clinicians should be aware of these risk factors representing more severe CCHS with earlier manifestation needing tracheostomy. Higher mortality among nontracheostomy group highlights the need for considering tracheostomy in caring for children with CCHS.

Jaw Thrust: A Simple Predictor of Success in Mandibular Distraction Osteogenesis.

The hypoplastic mandible in the congenital condition Pierre Robin sequence (PRS) displaces the base of the tongue posteriorly, which results in upper airway obstruction (UAO) that can potentially be corrected with mandibular distraction osteogenesis (MDO). Jaw thrust (JT) is routinely performed during evaluation of the airway; similar to MDO, it projects the mandible and tongue anteriorly to open the airway. The authors demonstrate that JT can be used as a criterion to predict successful MDO outcomes in infants with PRS. The study was a single-center, retrospective chart review of infants diagnosed with PRS between 2016 and 2023. Data regarding their demographics, comorbid diagnoses, JT success, airway anomalies, laryngeal grade of view, apnea-hypopnea index, and perioperative course were statistically analyzed. Of the 16 patients included in the study, 11 had successful relief of their airway obstruction with JT and proceeded with MDO. The unsuccessful JT group had significantly greater proportions of females, birth prematurity, gastrostomies, tracheostomies, and longer hospital stays. In the successful JT group, both the mean laryngeal grade of view ( P =0.029) and mean apnea-hypopnea index ( P =0.025) improved significantly post-MDO. Post-MDO tracheostomy was also avoided in all but 1 patient who was not previously tracheostomized. There is no widely accepted algorithm to guide craniofacial surgeons on the optimal intervention for relieving UAO in infants with PRS. In our institutional experience, patients whose preoperative JT relieved UAO also successfully relieved UAO with MDO. In patients with PRS, JT may be a useful criterion for selecting appropriate candidates for MDO.

Neonatal Endotracheal Intubation: Comparison of Existing Formulae for Accuracy

Background There are several formulae proposed to calculate the ideal depth of insertion of the endotracheal tube (ETT) in neonates, none of which are universally accurate. Our objective is to identify the most accurate of these formulae and to determine the most suitable formula for babies weighing less than 1 kg. Methods This is a retro-prospective observational study conducted in a tertiary neonatal intensive care unit. All intubated babies, irrespective of their gestational age, were included in this study. Those with congenital airway anomalies or syndromes with involvement of the upper airway and those who required short-term ventilation restricted to the theatre complex were excluded. The ideal insertion depth was determined via a chest X-ray (CXR) with the ETT projecting between thoracic vertebrae 2 and 3. Predictions from eight formulae investigated in the Indian population were analysed using paired Wilcoxon tests and Bland–Altman plots. Results The sample size was 83, of which 16 weighed less than 1 kg. Neither weight-based nor naso-tragal length (NTL)-based formulae were universally accurate in the prediction of the ideal depth of insertion, and using either of the formulae resulted in a high rate of malpositioning. Amongst the NTL-based formulae, Tatwavedi and Singh’s adjustments worked better than the original. Conclusion The currently available formulae remain inaccurate in the prediction of the ideal length of insertion of ETT, more so in babies less than 1 kg in our study population.

Tracheobronchial abnormalities on computed tomography angiography in children with congenital heart disease.

To evaluate the assortment of tracheobronchial abnormalities on computed tomography angiography (CTA) in children with congenital heart disease (CHD). In this study approved by the Institute ethics committee, CTA studies of 182 children (age range: 2 days-8 years) with CHD, performed from July 2021 to March 2023 were analyzed. Two pediatric radiologists independently assessed the tracheobronchial airways (from the trachea to lobar bronchi) for developmental and branching anomalies and airway compromise (narrowing). In cases which demonstrated airway compromise, the extent and the cause of airway narrowing were evaluated, and the etiology were divided into extrinsic and intrinsic causes. Interobserver agreement between the two radiologists was calculated using kappa statistics. One hundred children demonstrated normal airway anatomy and no luminal narrowing. Airway narrowing was observed in 63 (34.6%) children (κ: 0.954), and developmental airway anomalies were seen in 32 (17.5%) children (κ: 0.935). Of the 63 children with airway narrowing, 47 (25.8%) children had extrinsic cause for narrowing, 11 (6%) children had intrinsic causes for narrowing, and 5 (2.7%) children had both intrinsic and extrinsic causes attributing to airway compromise. Significant airway narrowing (>50% reduction) was seen in 35 (19.2%) children (κ: 0.945). Tracheobronchial airway abnormalities are frequently associated in children with CHD and need to be appraised preoperatively. Cross-sectional imaging with CTA provides excellent information on tracheobronchial airway anatomy and caliber as well as delineates the possible etiology of airway narrowing, thus accurately diagnosing airway anomalies.

Incidence, prevalence, and pattern of medical service utilization of children's rare lung diseases in South Korea.

Children's rare lung diseases are a heterogeneous group of rare lung diseases with significant morbidity and mortality. There is very limited information on the incidence and prevalence of children's rare lung diseases in Asia. We investigated the nationwide incidence, prevalence, and pattern of medical service utilization of children's rare lung diseases in Korea. We studied patients who were diagnosed with rare lung diseases coded per International Statistical Classification of Diseases and Related Health Problems, 10th Edition and registered in the national rare diseases database of confirmed patients. Data was extracted from the Korean National Health Insurance Service Claims database over 2019-2021. Average incidence rate was 12.9 new cases per million children per year, and average prevalence rate was 60.2 cases per million children during the study period of 2019-2021. We found that more than 65% of new cases were diagnosed before 2 years of age. ChILD, primary ciliary dyskinesia, and cystic fibrosis were usually diagnosed after 6 years of age. Congenital airway and lung anomalies were often diagnosed before 2 years of age. Busan and Gyeongsangnam-do residents tended to visit hospitals near their place of residence, while residents of other areas tended to visit hospitals in Seoul regardless of their area of residence. We examined the epidemiology of rare lung diseases in children in South Korea. Our estimation of the incidence and prevalence could be used for sustainable health care and equitable distribution of health care resources.

Bridging Bronchus – An Unsuspected Airway Anomaly Associated with Congenital Heart Disease: A Case Report with Review of Literature

Abstract Background: The association of airway anomalies with congenital heart disease (CHD) is common, but often remains undetected, due to a lack of awareness. We describe the unfortunate demise of an infant with CHD due to delayed diagnosis of a bridging bronchus (BB) with multifocal bronchial stenosis. Clinical Description: An 18-month-old boy, who was a known case of ventricular septal defect (VSD), was hospitalized for the third time with symptoms of pneumonia and congestive heart failure. He also had intermittent stridor and wheeze similar to his earlier illnesses. Management and Outcome: After stabilization with bubble continuous positive airway pressure, antibiotics, and diuretics, he underwent surgery for the VSD and got extubated successfully on day 3. Subsequently, however, he failed to get weaned off further from respiratory support and started having recurrent episodes of stridor along with suprasternal retractions and wheeze. Computerized tomography (CT) showed BB with multifocal stenosis of the airway and sequestration of the left lower lobe of the lung. He developed pneumonia and succumbed to the illness before he could be considered for surgical correction of the airway anomalies. Conclusion: Awareness about associated airway anomalies and their preoperative detection may alter prognostication, parental counseling, surgical approach, and final outcome.

Fighting to Breathe and Fighting for Health-Related Quality of Life: Measuring the Impact of Being Dependent on Technology for Breathing on the Child and Their Caregiver.

Medical advancement has enabled children to survive congenital airway anomalies, rare diseases and critical illnesses with medical technology including tracheostomies and long-term ventilation to support breathing. This study aimed to assess (1) the validity of the EQ-TIPS and EQ-5D-Y-3L in children dependent on technology and (2) the impact of caring for these children on the EQ-5D-5L and CarerQoL. Caregivers of children aged 1 month to 18 years completed the EQ-TIPS or EQ-5D-Y-3L, Pediatric Quality of Life Inventory (PedsQL) and Paediatric Tracheostomy Health Status Instrument(PTHSI) to reflect the child's health. In addition, caregivers self-completed the EQ-5D-5L and CarerQoL. Reports of problems on EQ dimensions were compared across age groups with the Fisher's exact test. Spearman and Pearson's correlation coefficients and Kruskal-Wallis H-test were used to explore the association between caregiver and child scores, concurrent validity, and known-group validity of the EQ-TIPS and EQ-5D-Y-3L. Responses from 144 caregivers were collected, 66 for children aged 1 month to 4 years completing EQ-TIPS and 78 for children aged 5-18 years completing EQ-5D-Y-3L. The EQ-TIPS showed a higher report of no problems for social interaction for children aged 1-12 months (p = 0.040) than the older age groups, there were however no differences in the level sum score (LSS) or EQ Visual Analogue Scale scores between the age groups. The EQ-5D-Y-3L showed a significantly less report of problems for mobility (p = 0.013) and usual activities (p = 0.006) for children aged 5-7 years compared with children aged 8-12 and children aged 13-18 years. Similarly, the 5-7 years of age group had a significantly lower EQ-5D-Y-3L LSS compared with the older groups (H = 12.08, p = 0.002). The EQ-TIPS and EQ-5D-Y-3L showed moderate-to-strong associations with the PedsQL. EQ-TIPS median LSS was able to differentiate between groups on the clinical prognosis with a better health-related quality of life (HRQoL) in those where weaning from technology is possible compared with those where weaning is not possible (H = 18.98, p = 0.011). The EQ-5D-Y-3L can discriminate between breathing technology, where those with only a tracheostomy reported better HRQoL (H = 8.92, p = 0.012), and between mild and moderate clinical severity (H = 19.42, p < 0.001). Neither the PedsQL nor the PTHSI was able to discriminate between these groups across the age range. Caregiver and child HRQoL scores showed moderate-to-strong associations. The EQ-TIPS and EQ-5D-Y-3L showed good validity in children dependent on the technology for breathing. The EQ-TIPS and EQ-5D-Y-3L LSS were all able to differentiate between children with known clinical variables and outperformed both the PedsQL and PTHSI, making them preferable for intervention research. The caregiver scores are associated with the child HRQoL scores and thus a spill-over should be accounted for in any interventions targeting this cohort. It is recommended that future studies investigate the reliability and responsiveness of these measures in children dependent on technology for breathing.

Knowledge and attitudes surrounding breastfeeding in pediatric otolaryngology: A survey study

ObjectiveThis survey study seeks to understand the knowledge and attitudes of pediatric otolaryngologists around breastfeeding to potentially inform future educational efforts. MethodsThis cross-sectional survey recruited 59 pediatric otolaryngologists from an international WhatsApp group comprising 213 members over a four-week period. Demographics, knowledge, attitudes, and experiences with breastfeeding were investigated using Likert scales. Descriptive statistics and correlational analyses were conducted. Statistical significance was set at p < 0.05. ResultsThe majority of participants were women (59%) and had children (86%). Most participants and/or their partners breastfed for 4–12 months (67%). Previous breastfeeding education was limited in both medical school (20%) and residency (15%). Most agreed that otolaryngologists should be knowledgeable about breastfeeding (83%), however men respondents felt significantly less comfortable counselling (p < 0.003), addressing difficulties (p < 0.044), and suggesting means to change milk supply (p < 0.007). Knowledge gaps were identified with assessing aspiration risk and airway anomalies. Breastfeeding experience did not significantly influence attitudes and comfort around breastfeeding, or the knowledge of participants. ConclusionWhile attitudes towards breastfeeding amongst pediatric otolaryngologists are very positive, degrees of comfort and knowledge are more limited, especially amongst men otolaryngologists. Future research should consider exploring the efficacy of educational efforts in Otolaryngology for improving the support offered to breastfeeding dyads.

A case series of pneumonia beyond usual infections in children

Pneumonia is the most common cause of mortality in under-five children worldwide. Largely, viral pneumonia is the most common cause of pneumonia in children across all age groups. We need to think outside the jukebox while dealing with cases of recurrent or persistent pneumonia. A few uncommon causes of persistent or recurrent pneumonia are primary or secondary immunodeficiencies, airway anomalies, infection with Mycobacterium tuberculosis complex, aspiration pneumonia, and severe gastroesophageal reflux. We present a few uncommon presentations of pneumonia in children, which can pose a significant diagnostic challenge in a resource-limited setting.
