[EX Q]: Abstract: Yersinia enterocolitica was cultured from feces of 122 symptomatic adults in a single facility using selective culture media; all isolates were confirmed in an independent reference laboratory. Of 128 isolates, multiple serotypes were defined and all were biochemically typical for Yersinia enterocolitica. Other agents were seen in 20 patients; of these, seven were Yersinia fredriksenii and six were Clostridium difficile. Diarrhea (80%) and abdominal pain (64%) were common, whereas other features such as fever (9%) and bloody stools (8%) were unusual. Use of antibiotics (24%) or opiates (28%) in the month before culture was common. The terminal ileum was seen radiographically in 20 patients, but only two barium studies showed abnormalities. Fiberoptic endoscopy and biopsy studies, done in greater than 50% of the cases, showed minimal or no changes in most patients. However, 3 patients had pseudomembranous colitis with concomitant Clostridium difficile cytotoxin and 7 had diffuse severe colitis. New culture techniques, and possibly geographic differences, have contributed to the high isolation rates of this organism. Yersinia enterocolitica occurs sporadically, involves a variety of serotypes, and is associated with a broader clinical spectrum than was formerly appreciated.

[EX Q]: Abstract: In order to examine the effectiveness and safety of hydraulic resistance strength training in young males, 26 pre-pubertal males (mean age = 8.2 +/- 1.3 yr) completed a 14-wk strength training study. Subjects were evaluated before and after the 14-wk experimental period for pubertal state (Tanner's sexual maturity rating, serum testosterone, and serum dihydroepiandrosterone sulfate). Effectiveness of the strength training program was determined by measuring pre-post differences in: isokinetic strength for flexion and extension at the knee and elbow joints at two speeds (30 degrees and 90 degrees X s-1) (KIN COM, Chattecx, Inc., Chattanooga, TN), flexibility, standing long jump, vertical jump, body composition parameters, maximal oxygen consumption, and creatinine phosphokinase. Safety of strength training was assessed by biphasic musculoskeletal scintigraphy before and after the program and by physician evaluation of complaints by subjects. Strength training subjects (N = 16) participated in a 45 min/session, 3 session/wk, 14-wk supervised strength training program with an attendance rate of 91.5%. Participants performed concentric work using hydraulic resistance equipment (Hydra-Fitness Industries, Belton, TX). Eccentric work was not performed. Control subjects (N = 10) did not strength train but did participate in sport activities and activities of daily living. Results indicated that strength training subjects increased isokinetic strength as a result of strength training (average concentric work/repetition increases by 18.5 to 36.6% for the eight motions tested; torque scores over the first 90% of the range of motion increases by 13.1 to 45.1% for the eight motions tested). These changes were significantly greater than changes seen in the control group (P less than 0.05). Strength training subjects also demonstrated significant improvements (as compared to control subjects) in vertical jump (+10.4%), flexibility (+8.4%), and maximal oxygen consumption [+19.4% (l X min-1), +13.8% (ml X kg X min-1)] after the experimental period. Musculoskeletal scintigraphy revealed no evidence of damage to epiphyses, bone, or muscle as a result of strength training. Only one strength training-related injury was reported (left shoulder pain, 3 strength training sessions missed). In contrast, six strength training subjects sustained injuries during activities of daily living, resulting in 47 missed strength training sessions. It was concluded that, in the short term, supervised concentric strength training using hydraulic resistance equipment is safe and effective in pre-pubertal boys.

[EX Q]: Abstract: A rabbit inhalation injury model using a dual tracer radioactive isotope technique (Rowland et al., 1986), has been utilized with small- and medium-sized molecular weight tracers. There is oedema formation at 2 h after smoke inhalation or fluid resuscitation and especially with the combination of inhalation injury and fluid resuscitation [corrected]. This oedema appears to have decreased by 24 h post-injury. There does not appear to be any difference between the small- and medium-sized tracers in the transit times of tracer in the lung vascular compartment. The increases in extravascular water volume have been confirmed by gravimetric analyses of the lungs. Thus the pulmonary oedema in the rabbit animal model is detectable within 2 h post-injury, with a return towards normal values some time within 24 h if fluid challenged for short periods. Fluid resuscitation exacerbates the amount of oedema that developed. The onset of pulmonary oedema may therefore be earlier than previously seen clinically, and fluid resuscitation modifications may be of benefit in smoke inhalation injury.
