ABSTRACT
Central airway obstruction can result from various benign and malignant conditions, and often requires prompt palliation. The efficacies of a variety of bronchoscopic techniques for the treatment of central airway obstruction such as electrocautery, laser, brachytherapy, argon plasma coagulation and cryotherapy have been established. An insulation-tipped diathermic knife-2 (IT knife-2) was initially introduced for gastrointestinal endoscopic submucosal dissection and has been used globally as a safe and effective instrument. However, its use has not been reported for the treatment of endotracheal or endobronchial lesions. Here, we report the case of central airway obstruction in a 65-year-old male due to malignancy and a 52-year-old-female with post-radiation bronchial stenosis that were treated successfully with the IT-knife-2 via flexible bronchoscopy.

Aerococcus viridans is a rare pathogen in humans, with only six cases of A. viridans urinary tract infections reported worldwide. Nosocomial urinary tract infections with bacteremia caused by A. viridians are even rarer, with no prior reports of urosepsis caused by A. viridans occurring in the Republic of Korea. Here we report a case of urosepsis caused by A. viridans in a 79 year-old female nursing home resident. The patient was admitted to the hospital presenting a fever of 39degrees C, chills, and oliguria for two days prior to admission. Urine culture yielded a robust growth of 105 CFU/mL of A. viridians, with blood culture positive for the same organism. Following diagnosis, the patient was treated with ciprofloxacin intravenously for 2 weeks, resulting in clearance of the infection and a full recovery from urosepsis. Although A. viridans is rarely associated with human infections, this case shows that, under the right conditions, it can be responsible for severe infections like urosepsis.

Intramural hematoma of the esophagus (IHE) is an uncommon form of esophageal injury, which may be an intermediate of mucosal tear (Mallory-Weiss syndrome) or transmural rupture (Boerhaave's syndrome). To date, the pathogenesis of IHE has not been well documented. IHE may occur within the submucosal layer of the esophagus following dissection of the mucosa. The most commonly presented symptoms are sudden retrosternal pain, dysphagia and hematemesis. The disorder can occur spontaneously or secondarily to trauma. In this report, we present a case of IHE which occurred after endoscopic biopsy and was recovered following conservative management in a patient who was taking long-term aspirin medication.

Paradoxical embolism is a kind of stroke caused by embolism of thrombus of venous origin through a lateral opening in the heart, such as a patent foramen ovale (PFO). Although the most frequent manifestation of paradoxical embolism is cryptogenic stroke, noncerebral paradoxical embolism is also associated with PFO. We experienced a case of cryptogenic renal infarction in a previously healthy 70-year-old man. He had no cardiac thrombus on transthoracic echocardiography and electrocardiogram revealed a normal sinus rhythm. Because it was cryptogenic renal infarction, we performed transesophageal echocardiography with microbubble test. Microbubble test using agitated saline proved the presence of right-to-left shunt and patent foramen ovale was diagnosed. We also performed lower leg doppler ultrasonogram, but there was no evidence of deep vein thrombosis. Although only the presence of a right-to-left shunt is not enough to establish the diagnosis of paradoxical embolism, it is uncommon for the source of the embolism to be identified. In this case, we concluded that paradoxical embolism is the cause of renal embolism. We report paradoxical renal embolism through PFO with review of relevant literatures.
