We describe a case of tracheobronchial inhalation of a bead by a five-year-old girl in Djibouti. The bead was extracted using a Fogarty balloon catheter passed through the rigid bronchoscope without complication. This kind of accident is not exceptional and we discuss the management of such cases with limited diagnostic tools and therapeutic environments.

The main sources of natural background radiation are radon, thoron and their progeny, which may cause health risks to humans. Keeping in mind the importance of the subject, three samples each from 10 selected residential areas, including the centre of Babylon Governorate, Iraq, and its districts, were collected. Concentration of radon and thoron was measured using solid-state track detectors (CR-39).

Tracheobronchial foreign body (TFB) aspiration in adults is uncommon but can be life-threatening, often due to differences in airway sizes and reflexes. Symptoms associated with TFB are typically choking episodes followed by cough and dyspnea, but sometimes it can lead to acute asphyxiation. Chest radiography and computed tomography can provide information about the foreign body, its characteristics, and its location, however, bronchoscopy remains the preferred method for diagnosis and removal.

A computational fluid dynamics (CFD) model coupled with discrete elements methods (DEM) is used to predict the transport and deposition of the aerosol. The results are compared to experimental and numerical data available in the literature to study and quantify the impact of the modeling parameters and numerical assumptions.

The design and development of engineered micro and nano-carriers offering superior therapeutic performance compared to traditional delivery forms, are crucial in pharmaceutical research. Aerosolization and inhalation of carriers with improved solubility/stability of insoluble drugs, has huge potential for targeted drug delivery (DD) in various pulmonary diseases. Indeed, dedicated carriers must meet specific dimensional rules for proper lung delivery.

The shape of environmental aerosols contributes to the discrepancy in their dynamic behavior compared to spherical particles, which have received inadequate consideration. We reported deposition patterns of aerosols and aerosol-transmissible pathogens in real human respiratory systems, taking into account their actual shape, using a validated computational-based model. We found that the shape of the aerosols significantly influenced its deposits and accessibility within the respiratory system, significantly in the tracheobronchial region.
