RESUMEN
Myoepithelioma is a rare salivary gland neoplasm. They most commonly affect the major and minor salivary glands with the parotid gland being the most common, approximately 40%. Only 1% of all salivary gland neoplasms are myoepitheliomas. Myoepithelioma is usually a benign tumor arising from neoplastic myoepithelial or basket cells which are found between the basement membrane and the basal plasma membrane of acinar cells. They also contain multiple cellular elements. We present a case of a 73-year-old female with myoepithelioma of the parotid gland, an extremely rare neoplasm. There have been approximately 42 cases reported through 1985 and fewer than 100 cases through 1993. We will discuss the clinical presentation, pathophysiology, diagnosis, and treatment of such neoplasms.
RESUMEN
OBJECTIVES: The purpose of this study is to identify laryngeal symptoms and injuries in self-extubated patients. METHODS: A retrospective chart review was conducted to identify symptoms and clinical findings associated with self-extubation. A novel scoring system was developed and used to quantify these findings. Symptom score included all symptoms that patients reported after self-extubation. Clinical score consisted of laryngeal findings visualized on nasopharyngeal laryngoscopy. Finally, a total self-extubation score was calculated as the sum of the symptom and clinical scores. Additionally, duration of intubation and endotracheal tube size were correlated with these scores. RESULTS: Sixty (n = 60) patients who self-extubated in our institution's intensive care unit were identified. Average calculated symptom, clinical, and total self-extubation scores were 0.92, 1.43, and 2.35, respectively. The most common symptom observed was hoarseness (62%), while the most common clinical finding was posterior laryngeal edema (58%). A significant positive correlation was found between duration of intubation and both symptom score and total self-extubation score (r = 0.314, P = .008 and r = 0.223, P = .05, respectively). Symptom score predicted clinical score with a significant positive correlation present (r = 0.278, P = .02). CONCLUSIONS: This study demonstrates that the majority of self-extubated patients have laryngeal symptoms and clinical findings. A comprehensive, multidisciplinary evaluation is warranted for self-extubations.
