McCarthy et al. in their article "Temperature Greater Than or Equal to 40 C in Children Less Than 24 Months of Age: A Prospective Study" (Pediatrics 59:663, May 1977) recommend using both WBC count (≥ 15,000/cu mm) and ESR (≥ 30 mm/hr) for screening febrile young children for pneumonia or bacteremia. If either is elevated they suggest doing blood cultures and taking a chest roentgenogram. However, in 25% of their patients with bacteremia and 42% of their patients with pneumonia neither WBC count nor ESR was elevated, leaving a sizable false-negative group.

Foreign body aspiration (FBA) is a common incidence in young children. Leeches are rarely reported as FBA at any age. This study describes a 15-year-old female who presented with hemoptysis, hematemesis, coughs, melena, and anemia seven months prior to admission. Chest X-ray showed a round hyperdensity in the right lower lobe. A chest computed tomography (CT) demonstrated an area of consolidation and surrounding ground glass opacities in the right lower lobe. Hematological investigations revealed anemia. Finally, bronchoscopy was performed and a 5 cm leech was found within the rightB7-8bronchus and removed by forceps and a Dormia basket.

Thymic hyperplasia is usually an asymptomatic condition observed in infancy. A five-week-old boy presented with respiratory distress and feeding disorder, in which chest X-ray and bronchoscopy revealed a strong laryngotracheal displacement. Sonography and MRI confirmed the diagnosis of a thymic hyperplasia. Corticosteroid therapy led to improvement of clinical symptoms. Thymic hyperplasia may lead to laryngo-tracheal displacement and respiratory distress in neonates and young children.

Abstract So far, COVID-19, the novel coronavirus, continues to spread rapidly in most countries of the world, putting people's lives at risk. According to the WHO, respiratory infections occur primarily in the majority of patients treated with COVID-19. For decades, chest X-ray (CXR) technologies have proven their ability to accurately detect and treat respiratory diseases. Deep learning techniques, as well as the availability of a large number of CXR samples, have made a significant contribution to the fight against this pandemic. However, the most common screening methods are based on 2D CNNs, since 3D counterparts are enormously costly and labor-intensive. In this study, a hybrid 2D/3D convolutional neural network (CNN) architecture for COVID-19 screening using CXRs has been developed. The proposed architecture consists of the incorporation of a pre-trained deep model (VGG-16) and a shallow 3D CNN, combined with a depth-wise separable convolution layer and a spatial pyramid pooling module (SPP). Specifically, the depth-wise separable convolution helps to preserve the useful features while reducing the computational burden of the model. The SPP module is designed to extract multi-level representations from intermediate ones. Experimental results show that the proposed framework can achieve reasonable performances when evaluated on a collected dataset (3 classes: COVID-19, Pneumonia, and Normal). Notably, it achieved a sensitivity of 98.33%, a specificity of 98.68% and an overall accuracy of 96.91%

Pulmonary hypoplasia (PH) is a developmental anomaly of the lung parenchyma, characterized by a decrease in the number and size of airways, alveoli and vessels. We present a case of a 31-year-old patient with a history of chronic productive cough and frequent respiratory infections, who was referred for investigation of abnormal chest x-ray. The combination of chest computed tomography (CT) and bronchoscopy set the diagnosis of left pulmonary hypoplasia and the patient was treated surgically with a left pneumonectomy. PH is usually diagnosed immediately after birth, causing severe respiratory failure with high mortality. The less severe, unilateral forms can possibly survive by causing compensatory hyperinflation of the other lung and remain undiagnosed until adulthood, presenting either asymptomatic or with symptoms of chronic bronchitis and recurrent respiratory infections. Chest CT is considered the imaging technique of choice for the diagnosis and for the differential diagnosis from other congenital or acquired conditions. The treatment is usually conservative, although surgical resection is indicated in cases of severe cystic changes and intense symptomatology.

The Coronavirus disease outbreak result in many people to have severe respira- tory problems and it was recognized as a global health threat. Since the virus is targeting the lungs in the human body initially, chest x-ray imaging features were considered to be useful for the detection of the infection in the early stage. In this study, the chest x-ray data of 130 infected patients from an open data source that referenced Cohen J. Morrison P. Dao L., 2020 was used to build a CNN( Convolutional Neural-Network) model for the early detection of the disease. The model was trained with both infected and not-infected peoples’ chest x-ray images with 100 epochs which led to 0.98 accuracy finally. In order to use this model as a professional diagnosis element, it is highly recommended it be improved with more images and the model can be restructured to get a better accuracy.

Program Version

Background and objectives: Respiratory infection is the second most common disease in pediatrics presented to the emergency department. Imaging modalities used for diagnosis, and follow up duration of each type of infection should be studied for best outcome for those patients. We aimed to find the optimum imaging follow up protocol for pediatrics with respiratory infections. Methods and Results: Retrospective study included 500 pediatric patients ranging in age from one month to 15 years, presented with respiratory infection. Radiological findings, numbers and results of follow up were collected and statistically analyzed using SPSS program version 23. Bronchitis represented the commonest finding (43%), followed by pneumonia (35%). All patients had initial chest X-ray. CT was done for 79 patients. 218 patients had radiological follow up. The number of follow up ranged from 1 to 51 with the average number was 26. Interpretation and Conclusions: Bronchitis is a clinical diagnosis that does not usually need imaging. Pneumonia is diagnosed clinically aided with X ray in severe cases and follow up may be needed after 4 weeks. X ray and CT are mandatory for the initial diagnosis of TB and follow up should be done after 6 months. Cystic fibrosis needs clinical follow up and annual imaging unless complications arise. Pulmonary abscess needs follow up after treatment.

Kartagener syndrome is a rare genetic disorder which includes a triad of bronchiectasis, chronic sinusitis, and situs inversus. Primary ciliary dyskinesia (PCD) can be one of the causes of the above symptoms in this syndrome. This study aims to contribute toward a greater understanding of Kartagener syndrome by reporting a rare case. This 16-year-old boy was hospitalized in the internal ward of 22 Bahman Hospital in Gonabad on February 23, 2016 and presented with suspected Kartagener syndrome and PCD, whose diagnosis of Kartagener syndrome and PCD was confirmed according to biopsy of the nose and antitrypsin test. The patient also underwent electrocardiography, chest X-ray, pelvic and abdominal ultrasound, and computed tomography scan with high resolution and no contrast of the chest, abdomen, and sinuses. As a rare disorder, Kartagener syndrome should be borne in mind in differential diagnoses of chronic respiratory infections and must be diagnosed as early as possible to improve patient’s quality of life.
