ABSTRACT
Mycobacterium avium has been traditionally described as an opportunistic organism that causes disseminated disease in human immunodeficiency virus-positive patients and acts as a pulmonary pathogen in patients with underlying lung diseases such as chronic obstructive pulmonary disease or previously treated tuberculosis. Infections caused by M. avium in immunocompetent hosts usually manifest as 2 distinct subtypes, the upper lobe cavitary form and the nodular bronchiectatic form. However endobronchial lesions due to M. avium infections in immunocompetent host are reasonably rare, and there are no reports of this condition in Korea. We report here a case of endobronchial lesions involved in an M. avium infection in an immunocompetent 21 year-old female patient with no preexisting lung disease.

Direct arterial pressure monitoring by means of an intra-arterial catheter has been considered benefit for assessment of the critically ill patients, safe conduct of controlled hypotension and frequent obtaining arterial samples for blood gas analysis. However in stead of these advantages, there would be high incidence of potential complications of arterial catheterization, such as pain, trauma to the artery and surrounding tissues(e. g., nerve), hematoma, infection, thrombosis, and distal embolization of air, clot, pieces of the catheter, and other debris. We have recently experienced an unexpected episode of amputation of the upper extremity resulting from axillary arterial occlusion following accidental injection of diphenylhydantoin through the radial arterial catheter in 57 year old neurosurgical patient. To prevent these serious and unexpected complications following arterial cannulation, we have to keep a continuous interest and vigilance to those who have invasive monitorings and those who are stranger to handle the arterial cannulation.
