Introduction: Mucopolysaccharidosis (MPS) type IVA usually results in airway obstruction due to thoracic cage deformity and crowding of intrathoracic structures, causing tracheal compression by the tortuous innominate artery.
Objectives: To offer an alternative and effective method in dealing with the challenged deformity of the airway in patients with MPS type IVA.
Methods: We present 3 patients with MPS type IVA who underwent airway stenting using Montgomery T-tube stents. Three-dimensional reconstructed computed tomography was essential to design the T-tube and evaluate the anatomical relationship between the innominate artery and the trachea. The Y-shaped Montgomery Pediatric Safe-T-Tube™ is more suitable for MPS type IVA. Regular follow-ups using fiberoptic bronchoscopy are necessary to evaluate the complications.
Results: All 3 patients had good outcomes during the follow-ups until present, despite the complication of granulation formation, which was resolved by revising the limbs of the T-tube.
Conclusions: T-tube stents placed below the vocal cord may restore airway patency and preserve laryngeal function, including respiration, phonation, and swallowing, in patients with MPS type IVA.

Background: The primary aim of this study was to quantitatively analysis the acetabular morphological feature and 2D/3D coverage of the Crowe IV DDH hip, dividing into subgroups by the false acetabulum. The secondary aim was to propose a 3D bone mapping to determine acetabular bone defect analysis from the perspective of the implanted simulation.
Methods: A total of 53 Crowe IV hips (27 hips without the false acetabulum in IVa group and 26 hips in IVb group) and 40 normal hips met the inclusion criteria and were retrospectively evaluated.

Background And Purpose: Cervical cancer is the most prevalent type of cancer among women in numerous low and middle-income countries. Tandem-based applicator is a widely used technique in High Dose Rate Intercavitary Brachytherapy (HDR-ICBT) for treating cervical cancer. For cases where central tandem insertion is not feasible due to patient-specific conditions, a ring-only applicator is used as an alternative.

In many countries worldwide, NO emissions currently decrease as a result of pollution control, while NH emissions stagnate or continue to increase. Little is known about horizontal deposition of NO and NH, the oxidation/neutralization products of these primary pollutants. To close the knowledge gap, we studied atmospheric inputs of NO and NH at two mountain-top sites near the Czech-German-Polish borders during winter.
