Foreign Body in the Airway Mimicking Tumour in an Adult: A Case Report.

Foreign body (FB) aspiration is an infrequent cause of respiratory distress in adults. Advancing age, central nervous system disorders or trauma, drug or alcohol addiction, neuromuscular diseases, and mental health issues and illnesses are the main risk factors. The authors present an atypical clinical presentation of a 3-week-lasting foreign body aspiration mimicking a tumour that led to severe acute respiratory insufficiency and required aggressive artificial lung ventilation. Diagnosis of FB was based on the results of the chest computed tomography (CT) scans and flexible bronchoscopy, which, however, initially assumed a neoplastic disease in the right main bronchus. During FB extraction via flexible fiberoptic bronchoscopy inserted through an 8.5 mm endotracheal tube high-frequency ventilation through a catheter placed between the vocal cords was used to ensure adequate alveolar ventilation and maintain sufficient oxygenation. After extraction of the FB, thoracosurgical intervention was performed to resolve empyema as a septic complication of the FB aspiration. After this therapy, a complete resolution of pleural empyema and lung atelectasis was observed.

Occurrence of butyrylcholinesterase polymorphisms in patients undergoing surgery in Slovakia.

Background: Post-operative residual curarization is a persisting problem, characterized by muscle fatigue, exhaustion or paresis, caused by the use of neuromuscular blocking agents with prolonged postoperative effect. Genetically, determined changes in cholinesterase activity can be a major reason for persistent muscle blockade after administration of muscle relaxants. Methods: Regarding the subsistence of polymorphisms in the plasma cholinesterase gene causing change in enzyme activity and metabolism of applied drugs, we investigated the frequency of two polymorphisms known to reduce its activity significantly in patients undergoing surgery. Results: Primary results show a relatively high occurrence of plasma cholinesterase K risk allele (18.75%). Conclusion: Characterization of the lacking information about genetic background of changes in plasma cholinesterase activity within Slovakia may allow for easier decision-making in clinical practice when selecting alternative neuromuscular blocking and also reversal agents.
