We report a 70-year-old man who presented symptoms resembling those of meningoencephalitis and who was subsequently diagnosed as having a crowned dens syndrome
Successful management of penetrating injury to the trachea is rare, especially in Japan. A 32-year-old female attempted suicide by stabbing herself in the throat with a knife, and at operation the trachea was found to be completely disrupted. A median sternotomy made possible end-to-end anastomosis of the trachea. All other important organs including the great vessels, esophagus, and lungs were intact, but the pleura was open on the right side. The patient was managed under heavy sedation and with controlled ventilation for more than a week postoperatively, because of her suspected mental condition. She was extubated on postoperative day 13 and transferred to a mental hospital on day 16. We concluded that early diagnosis and surgical repair were important for the successful management of this patient with tracheal disruption.
A 72-year-old man was hospitalized with asymptomatic hyponatremia. Despite hyponatremia, urinary sodiumexcretion with urine osmolality exceeding plasma osmolality persisted. Plasma vasopressin levels were high and independent of plasma osmolality during hypertonic saline infusion. Computed tomography of the chest showed enlarged mediastinal and right hilar lymph nodes. Microscopically, a specimen of lymphnodes obtained by biopsy represented vasopressinproducing small cell lung carcinoma. Chemotherapy plus irradiation improved the hyponatremia. Thus, careful evaluation is necessary to determine the cause of hyponatremia disorders in elderly patients. (Internal Medicine 37: 950-954, 1998)
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
