[Bilateral pneumothorax during awake fiberoptic intubation : A rare complication of bronchoscopy]. / Beidseitiger Pneumothorax bei fiberoptischer Wachintubation : Eine seltene Komplikation der Bronchoskopie.

An 86-year-old woman was scheduled for surgical treatment of a periprosthetic femoral fracture after a fall. Because of a known difficult airway due to multiple surgeries and radiation for cancer in the orofacial area, awake fiberoptic intubation was planned. During the fiberoptic maneuver the patient experienced a massive bout of coughing which resulted in large soft tissue emphysema and double-sided pneumothorax. This case reports a rare complication of fiberoptic intubation and airway management.

Developmentally regulated protein synthesis during intraperiplasmic growth of Bdellovibrio bacteriovorus 109J.

Bdellovibrio bacteriovorus 109J is an obligate intraperiplasmic predator of other Gram-negative bacteria. Collision with a suitable prey cell initiates a developmental sequence ultimately resulting in the destruction of the prey cell and the production of progeny bdellovibrios. Two-dimensional gel analysis of patterns of protein synthesis at various times in a synchronously growing culture of Bdellovibrio bacteriovorus 109J revealed over 30 polypeptides whose syntheses are developmentally regulated. The majority of these polypeptides fall into nine categories: attack phase specific or one of eight different kinetic groups expressed during the intraperiplasmic growth phase. The results indicate that Bdellovibrio bacteriovorus 109J has a complex system for regulating gene expression during its developmental cycle.
