Emergency intervention to preserve left ventricular function or right coronary artery dominant and collateral blood flow to left coronary arteries is important for improving the prognosis of patients with acute myocardial infarction due to left main coronary artery occlusion. If residual left main coronary artery stenosis is significant or other proximal coronary stenosis exists after catheter intervention, early coronary bypass surgery may improve long-term survival.

Background Yersinia pseudotuberculosis infection can occur in an immunocompromised host. Although rare, bacteremia due to Y. pseudotuberculosis may also occur in immunocompetent hosts. The prognosis and therapeutic strategy, especially for immunocompetent patients with Y. pseudotuberculosis bacteremia, however, remains unknown. Case presentation A 38-year-old Japanese man with a mood disorder presented to our hospital with fever and diarrhea. Chest computed tomography revealed consolidation in the right upper lobe with air bronchograms. He was diagnosed with pneumonia, and treatment with intravenous ceftriaxone and azithromycin was initiated. The ceftriaxone was replaced with doripenem and the azithromycin was discontinued following the detection of Gram-negative rod bacteria in 2 sets of blood culture tests. The isolated Gram-negative rod bacteria were confirmed to be Y. pseudotuberculosis. Thereafter, he developed septic shock. Doripenem was switched to cefmetazole, which was continued for 14 days. He recovered without relapse. Conclusions We herein report a case of septic shock due to Y. pseudotuberculosis infection in an adult immunocompetent patient. The appropriate microorganism tests and antibiotic therapy are necessary to treat patients with Y. pseudotuberculosis bacteremia.

The present findings suggest that higher serum lithium levels may be protective against suicide attempts in lithium therapy-naive individuals.

SUMMARY:Here, we report a case of pneumonia possibly caused by the aspiration of runoff water containing Chromobacterium haemolyticum. A 69-year-old man became intoxicated with alcohol, fell into a ditch, and lost consciousness after suffering a blow to the head. The lower half of his body was completely paralyzed because of damage to his spinal cord, and he aspirated runoff water from the ditch. Chest computed tomography scans revealed consolidation in the right upper lobe and bilateral lower lobes. A sputum culture detected gram-negative bacteria that was identified as C. haemolyticum. Antibacterial chemotherapy was initiated, and the clinical course was favorable. To the best of our knowledge, this is the first report of C. haemolyticum pneumonia in the literature.
