Case ReportsTracheoesophageal fistula with tracheal stenosis resulting from retained esophageal foreign body.
Although a foreign body ingestion is common in infants and young children, serious complication such as penetration of the esophagus is a relatively rare event. Delayed diagnosis may result from lack of classical symptoms and history, leading to serious result, even to death. A 2-year-old boy was admitted to the emergency room with dyspnea. ⋯ Chest X-ray and cervical CT scan revealed esophageal foreign body. Intraoperative findings showed a plastic material in the esophagus and tracheoesophageal fistula with tracheal stenosis as a complication of the retained foreign body. Therefore, we should keep in mind that foreign body can present atypical symptoms like respiratory symptoms, especially in infant and young children.

Case ReportsManagement of intraoral needle migration into the posterior cervical space.
Foreign bodies within the deep spaces of the neck pose infrequent but substantial risks involving migration, including infection, pseudoaneurysm formation, pneumothorax, hemopericardium, and embolization to the central circulation. A rare case of foreign body migration through the parapharyngeal space into the posterior cervical space is described from an intraoral needle shard. A 48-year-old male presented with a right neck tenderness, referred otalgia, and intermittent neck twitching after a needle fragment was lost during an inferior alveolar nerve block. ⋯ Sharp foreign bodies in the head and neck introduce an uncommon but high-impact risk of complications. Migration is often unpredictable in trajectory and time course. Early surgical removal is recommended for persistent symptoms, sustained migration, and localization to sites with critical structures.

Doxycycline reduces nitric oxide production in guinea pig inner ears.
Gentamicin application is an important therapeutic option to control vertigo spells in Ménière's disease. However, even in the case of low-dose intratympanic application, gentamicin might contribute to a pathological NO-increase leading to cochlear damage and hearing impairment. The study was performed to evaluate the nitric oxide (NO) reducing capacity of doxycycline in the inner ear after NO-induction by gentamicin. ⋯ The application of doxycycline might offer a new therapeutic approach to prevent NO-induced cochlea damage through ototoxic substances.
