Robotic versus vaginal urogynecologic surgery: a retrospective cohort study of perioperative complications in elderly women.

Objectives: The primary objective was to compare perioperative complications after robotic surgery (RS) versus vaginal surgery (VS) for apical prolapse repair in elderly women. The secondary objectives were to (1) assess whether tools designed to predict surgical morbidity, the American Society of Anesthesiologists (ASA) class and the Charlson Comorbidity Index (CCI), are useful in the elderly urogynecologic population and (2) to classify complications during urogynecologic apical procedures using the Dindo classification system.

Methods: We reviewed medical records of women 65 years or older who underwent RS or VS between March 2006 and April 2011.

Characterization of the systemic disease and ocular signs induced by experimental infection with Chlamydia psittaci in cats.

In addition to the commonly reported ocular signs, Chlamydia psittaci infection of kittens resulted in fever, lethargy, lameness and reduction in weight gain following ocular instillation of virulent organisms. The appearance of these systemic signs was late with respect to the appearance of ocular symptoms and occurred simultaneously with increasing levels of chlamydia-specific IgG. Measurement of acute phase reactants and IL-6 in plasma indicated that both became elevated concurrent with or slightly after the appearance of fever and remained elevated after the fever began to resolve.

Virulence of feline Chlamydia psittaci in mice is not a function of the major outer membrane protein (MOMP).

The virulent strain of feline Chlamydia psittaci, the Cello strain, produces conjunctivitis and upper respiratory disease in cats. This same strain produces a lethal disease in mice when inoculated intraperitoneally (i.p.

Evaluation of Chlamydia psittaci subfraction and subunit preparations for their protective capacities.

A mouse toxicity potency test was used to evaluate the protective capacity of Chlamydia psittaci (Baker strain) subfraction and subunit preparations. The elementary body (EB), Chlamydial outer membrane complex (COMC), major outer membrane protein (MOMP), lipopolysaccharide (LPS), and MOMP mixed together with LPS were utilized as antigens in vaccine preparation. The EBs and COMCs were prepared by centrifugation and detergent extraction as previously described for Chlamydia trachomatis.
