Abstract
OBJECTIVE To report on all complications experienced by patients with displaced intra-articular calcaneal fractures (DIACFs) following nonoperative management or open reduction internal fixation (ORIF). DESIGN Prospective, randomized, multicenter study. SETTING Four level I trauma centers. PATIENTS The patient population consisted of consecutive patients, age 17 to 65 at the time of injury, presenting to 1 of the centers with DIACFs between April 1991 and December 1998. INTERVENTIONS Patients were randomized to the nonoperative treatment group or to operative reduction using a lateral approach to the calcaneus. MAIN OUTCOME MEASUREMENTS Follow-up for patients was at 2 weeks, 6 weeks, 3 months, 12 months, 24 months, and once greater than 24 months following injury. At each follow-up interval, patients were assessed for the development of major and minor complications. After a minimum of 2-year follow-up, patients were asked to fill out a validated visual analogue scale questionnaire (VAS) and a general health review (SF-36). RESULTS There were 226 DIACFs (206 patients) in the ORIF group with 57 of 226 (25%) fractures (57 of 206 patients [28%]) having at least 1 major complication. Of 233 fractures (218 patients) nonoperatively managed, 42 (18%) (42 of 218 patients [19%]) developed at least 1 major complication (indirectly resulting in surgery). CONCLUSION Complications occur regardless of the management strategy chosen for DIACFs and despite management by experienced surgeons. Complications are a cause of significant morbidity for patients. Outcome scores in this study tend to support ORIF for calcaneal fractures. However, ORIF patients are more likely to develop complications. Certain patient populations (WCB and Sanders type IV) developed a high incidence of complications regardless of the management strategy chosen.

Abstract
The mtDNA genome has been implicated as playing a pivotal role in determining the longevity and success of the human lifespan. A PCR-RFLP methodology was used to identify polymorphic restriction enzyme sites within a 2643 bp region of the mtDNA genome and a table of genetic haplotypes for a healthy aged and a younger control cohort of patients was constructed. Forty-six different mtDNA haplotypes and 11 groups of related haplotypes were identified across the two age groups but statistical analysis failed to show any significant associations. The European J haplogroup, previously reported to be associated with longevity, was not found at an increased frequency within the Irish aged population (P=0.36). However, the haplotypes comprising the J haplogroup could be differentiated into two distinct branches by the presence or absence of the two polymorphic restriction sites, 16,389g and 16,000g. The branch of haplotypes defined by 16,389g displayed a significant increased frequency in the aged samples (8%) compared to the controls (1%), P=0.015. Inversely, the branch of haplotypes defined by 16,000g displayed a significant decreased frequency in the aged samples (4%) compared to the controls (13%), P=0.011. The polymorphism (mt5178A) associated with longevity in the Japanese was not found in the Irish population, while the polymorphism (mt9055A) associated with successful ageing in the French centenarians was found at an increased frequency in the Irish aged population (9%) compared to the younger control group (5%), but failed to reach a level of statistical significance, P=0.164.

Abstract
Mycoplasma bovis was detected in 134 (18 per cent) of 736 samples of bovine lung tissue collected from fatal pneumonia cases in the Republic of Ireland between April 1995 and December 1998. The cases occurred in 95 herds and recurred in four of them. Other respiratory pathogens were identified in 66 per cent of the M bovis-positive cases, with Pasteurella species, infectious bovine rhinotracheitis and parainfluenza 3 virus being most frequently detected. Mastitis and arthritis were less common clinical signs associated with M bovis infection; 22 cases of M bovis mastitis and five cases of M bovis arthritis were diagnosed in five herds.

Abstract
An indirect ELISA was used to detect antibodies to Mycoplasma bovis in milk samples collected from a herd with M bovis mastitis. Antibodies were detected in samples from nine cows which had developed clinical M bovis mastitis. Milk from only three consistently antigen-negative cows tested positive for M bovis antibodies. These results indicate the potential value of the indirect ELISA for the detection of cows which have recently developed M bovis mastitis during the early stages of an outbreak.

Abstract
We evaluated the ACCESS cardiac troponin I (cTnI) immunoassay as a marker for myocardial infarction (MI). Total imprecision was 6.0% to 13.5%, the minimum detectable concentration was 0.007 microg/L, and the limit of quantitation was 0.046 microg/L. Comparison of cTnI measurement between the ACCESS and Stratus systems (n = 114) showed a proportional difference: ACCESS cTnI = 0.0996 Stratus cTnI + 0.049 microg/L (r = 0.811). Fifty-nine of 61 ambulatory patients without cardiac symptoms had no detectable cTnI (95% range, 0.00 to 0.025 microg/L). The optimum cutoff for discriminating MI (n = 289, 45 with MI) was 0.15 microg/L by receiver operator characteristic curve analysis; at this cutoff, the ACCESS cTnI assay showed a sensitivity of 88.9% (95% CI, 79.7-98.1%) and specificity of 91.8% (95% CI, 88.4-95.2%). The ACCESS cTnI assay results showed 89.4% and 93.0% concordance with the MB isoenzyme of creatine kinase (CK-MB) mass and Stratus cTnI results, respectively, for classification of patients with suspected MI. The ACCESS cTnI assay appears to show sensitivity and specificity comparable with those of both CK-MB mass and Stratus cTnI assays for the diagnosis of MI in patients presenting within 12 h of onset of symptoms.

Abstract
The pharmacokinetics of propofol and ketamine administered together by infusion were investigated in four ponies. Blood propofol and plasma ketamine and norketamine concentrations were measured by high performance liquid chromatography. After premedication with detomidine (20 micrograms kg-1) anaesthesia was induced with ketamine (2.2 mg kg-1 intravenously). The trachea was intubated and the ponies were allowed to breathe 100 per cent oxygen. A bolus dose of propofol (0.5 mg kg-1) was then administered intravenously and propofol and ketamine were infused for 60 and 45 minutes, respectively. The average mean infusion rate of propofol was 0.136 mg kg-1 min-1, and the ketamine infusion rate was maintained at 50 micrograms kg-1 min-1. The mean (SD) elimination half-lives of propofol and ketamine were 69.0 (8.0) and 89.8 (26.7) minutes, the mean volumes of distribution at steady state were 0.894 (0.161) litre kg-1 and 1.432 (0.324) litre kg-1; the mean body clearances were 33.1 (4.5) and 23.9 (3.8) ml kg-1 min-1 and the mean residence times for the infusion were 87.1 (4.1) and 110.7 (8.2) minutes, respectively. Norketamine, the main metabolite of ketamine, was detected throughout the sampling period. The mean residence time for norketamine was 144 (16) minutes. All the ponies recovered quickly from the anaesthesia; the mean times to sternal recumbency and standing were 11.1 (5.3) and 30.0 (20.8) minutes, respectively, from the end of the infusion.

Abstract
Without question, much has been learned about the glycoprotein PSA in recent years. By increasing our understanding of this tumor marker's biochemical and physiologic properties, we will be able to improve its clinical utility. The discovery of the various molecular forms of PSA represents a significant advancement. Knowing the concentration and ratio of these PSA forms will be valuable in deciding which patients require further evaluation with transrectal ultrasound and prostate biopsy and which men can be monitored safely without undergoing further invasive testing. This information will be most valuable in treating the patient with a mildly elevated serum PSA level. Although assays are not yet available to detect specifically hK2, the striking similarities of hK2 to PSA, including selective expression in the prostate, suggest that this marker may also prove useful in prostate cancer management. Indeed, a new era of PSA testing has been entered, and the entire field of prostate cancer will benefit.

Abstract
Leucine enkephalin (Leu-enk) was coupled to both T and B cell antibodies in order to investigate the possibility of enhanced immunogenicity via targeted immunization. The two antibodies used were Hm x Mo CD3 and Gt x Mo Ig, respectively. The data indicate that while both antibody carriers enhanced the immunogenicity of Leu-enk, the use of the Hm x Mo CD3 antibody resulted in a greater number of mice with positive Leu-enk specific serum titers. 12 Leu-enk cell lines were produced and one, LE4H8, was chosen for characterization.

Abstract
The isotype of a monoclonal antibody is closely associated with its biologic activity. Certain immunoglobulin subclasses are more effective than others regarding their ability to execute complement-mediated lysis of cells, antibody-dependent cell-mediated cytotoxicity, and tumor localization. Many potential targets for cancer immunotherapy are tumor-associated antigens with high percentages of carbohydrate. Immunizations of mice with carbohydrate antigens usually produce IgM and IgG3 antibodies. The use of different adjuvants in immunization protocols has been associated with the induction of isotype-specific antibody responses. In experiments reported here, we compare the use of four different adjuvants on the generation of an IgG immune response to the carbohydrate-rich, tumor-associated antigen, CA-195. We report the production of IgG1 and IgG2a monoclonal antibodies (mAbs) to CA-195.

Abstract
The authors evaluated three cases of soft tissue chondromas in patients aged 55, 57, and 78 years. Two of the lesions occurred in the foot and one in the hand. All three patients had long histories (over 1 year) of a palpable mass and all three had roentgenograms showing well-demarcated lobulated soft tissue lesions with both central and peripheral calcifications. Recognition of this rare benign chondroid lesion on imaging studies is significant since it may be misinterpreted as an aggressive lesion or a primary synovial abnormality.

Abstract
Activity for many disabled persons often begins as therapy, but the additional rewards derived from exercise must be appreciated. Public attitudes toward disabled persons have changed during the last few decades, recently focusing on abilities rather than on disabilities. The family physician of patients with spinal cord injuries will assist in managing acute medical problems and the association with loss of some degree of physical capacity. Physicians also can guide these individuals to choose a life that remains active and interesting over a "house-bound," but safe, existence. Sensitivity and timing play key roles in establishing exercise as an intergral part of a disabled individuals' altered lifestyle. The physician can advocate increased access to wheelchairs and other facilities that make life easier for disabled individuals.

Abstract
The common acute lymphoblastic leukaemia antigen (CALLA/CD10) is a normal component of the circulating neutrophil cell surface membrane. In order to examine the potential functional significance of CALLA/CD10 we analysed the expression of this molecule on neutrophils isolated from thermal injury patients, since these patients have a well-documented constellation of neutrophil defects affecting their microbicidal functions. Expression of neutrophil CALLA/CD10 was monitored by indirect immunofluorescence and flow cytometry. We observed that CALLA/CD10 expression was quantitatively reduced on burn patient neutrophils, compared to healthy donors (P less than 0.001). In contrast, burn patient neutrophils expressed normal levels of class I HLA molecules and the C3bi receptor. Reduced expression of CALLA/CD10 was not associated with neutrophil activation or exposure to plasma 'factor(s)' in vivo. Analysis of normal bone marrow neutrophils by cell sorting indicated that expression of CALLA/CD10 occurs late in neutrophil maturation, since 25% of polymorphonucleated bone marrow neutrophils did not express cell surface CALLA/CD10. Attempts to examine the chemotactic responses of CALLA/CD10 positive and negative neutrophils from burn patients were hampered by previous exposure of these cells to chemoattractants in vivo. Collectively, our findings suggest that burn patient peripheral blood neutrophils may be deficient in CALLA/CD10 due to insufficient maturation time in the bone marrow following thermal injury.

Abstract
We have previously demonstrated that human neutrophils synthesize the common acute lymphoblastic leukemia antigen (CALLA/CD10). To determine whether CALLA/CD10-positive and -negative neutrophils have similar or distinct functional attributes, we sorted normal peripheral blood neutrophils for CALLA/CD10 expression and compared their chemotactic ability. Surprisingly, the low-frequency (approximately 5%), CALLA/CD10-negative neutrophils displayed a dramatically heightened chemotactic response to activated complement (C') that was (a) specific for C', (b) not observed with other minor subpopulations of neutrophils, (c) not due to previous activation in vivo or in vitro, and (d) apparently not due to an increase in C5a receptors. These results underscore the concept of neutrophil heterogeneity and prompt the hypothesis that CALLA/CD10-negative neutrophils may participate in an inflammatory response to trauma involving complement activation.
