Factorial validity of the short-form McGill pain questionnaire (SF-MPQ).

Although widely used, there have been few investigations of the factorial validity of the short-form McGill Pain Questionnaire (SF-MPQ; Melzack, 1987). Confirmatory factor analysis was performed on item responses to the SF-MPQ obtained from 188 patients with chronic back pain. Consistent with the original structure proposed by Melzack (1987), results indicated that the SF-MPQ is best represented by a two-factor solution. However, these findings are contrary to results obtained by Burckhardt and Bjelle (1994) who, using their Swedish version of the SF-MPQ, obtained a three-factor solution. Potential explanations for the disparity between the results of the two studies are explored and recommendations for continuing clinical and research applications are offered.

Factorial validity of the Childhood Trauma Questionnaire in men and women.

In an effort to confirm the factorial validity of the Childhood Trauma Questionnaire (CTQ) across sex, the items from the CTQ for 916 university students were subjected to confirmatory factor analysis. Results indicated that the factor structure for the CTQ was significantly different for men and women. For women, the items from the Physical Abuse subscale did not create a stable factor and thus appear not to be conceptually valid. Conversely, for men, the five-factor model provided a relatively good fit to the data. This investigation provides important information regarding sex differences in the factorial validity of the CTQ. Implications and future research directions are discussed.

Bile duct injury during laparoscopic cholecystectomy without operative cholangiography.

BACKGROUND: The role of operative cholangiography in the prevention of bile duct injuries is controversial. A prospective audit of biliary injury is presented. METHODS: Laparoscopic cholecystectomy without operative cholangiography was undertaken in a consecutive series of 1200 patients. All biliary injuries were recorded. RESULTS: Meticulous dissection proved to be a reliable safeguard against injury to the right hepatic, common hepatic and common bile ducts. However, four accessory ducts were sacrificed and localized injury to the common hepatic or common bile duct occurred in three patients. These injuries would not have been prevented by operative cholangiography. CONCLUSION: Operative cholangiography is not a prerequisite for the safe performance of laparoscopic cholecystectomy and cannot be relied upon to prevent all biliary injuries.

A temporary solution to reverse staging: the skin care evaluation sheet.

The National Pressure Ulcer Advisory Panel (NPUAP) has published recommendations over the last several years against the use of reverse staging to describe the healing of a pressure ulcer. Clinical studies have shown that as Stage IV pressure ulcers heal to more shallow depths, they do not replace lost muscle, subcutaneous fat, and dermis before they re-epithelialize. Instead the defect is filled with granulation tissue composed of endothelial cells, fibroblasts, collagen, and an extracellular matrix. The Minimum Data Set-2 (MDS-2) is a comprehensive assessment tool required to be completed on a quarterly basis in all long term care facilities that provide care to Medicare patients. Section M of the MDS-2 addresses skin condition and requires that pressure ulcers be staged as assessed within seven days of documentation, using the guidelines in that section. No mechanism currently exists to document progression of ulcer healing, leaving the practitioner no alternative but to restage the ulcer. This article presents one facility's effort to acknowledge the NPUAP recommendations, while complying with reimbursement screening methods.

'Efficient' timely evacuation of intracranial haematoma--the effect of transport direct to a specialist centre.

Patients with intracranial haematoma following head injury may have little primary brain injury, but sustain a secondary brain injury that can often be minimized by early evacuation of the haematoma. Rapid intervention by a neurosurgeon with early evacuation of the haematoma gives a better outcome. The timing of treatment in 403 patients with severe head injuries, admitted to the Royal London Hospital between January 1991 and December 1994 was examined. All cases had been transported directly from the accident scene by the Helicopter Emergency Medical Service because the local hospital did not have neurosurgical facilities. The median time to medical intervention was 15 min (95 per cent, confidence interval (CI) 14-16) and the median time to neurosurgery was 177 min (95 per cent, CI 171-195). As secondary interhospital transfer of patients with head injuries is known to increase the time to neurosurgical intervention and is a time of great risk of secondary insult to the brain, transfer direct from the scene of the accident to an appropriate centre allows a process of care that has been shown to be associated with a better outcome.

Measuring codependents' close relationships: a preliminary study.

A survey of clinical literature and input from addiction counselors yielded eight commonly assumed characteristics of codependents' relationships. These were defined in a manner amenable to measurement by the Acquaintance Description Form (Wright, 1985), and added to the standard form to provide a codependent version (ADF-C2). Forty-one women and 19 men awaiting or beginning codependent counseling responded to the ADF-C2, and to Friel's Codependency Assessment Inventory and forms soliciting background information. Thirty-nine women and 30 men from the general population provided a comparison group. Although tentative, results were encouraging concerning progress toward measuring codependents' relationships. Broad profiles for both women and men supported the foundational observation that codependents maintain strong commitments to their partners notwithstanding stress and unrewardingness. Specifically, codependent women showed five expected characteristics: Control, Exaggerated Responsibility, Worth Dependency, Rescue Orientation, and Change Orientation. Codependent men showed two: Control and Exaggerated Responsibility.

Strain and sex variation in the susceptibility to streptococcal cell wall-induced polyarthritis in the rat.

Sixteen inbred rat strains were examined for susceptibility and resistance to group A streptococcal cell wall-induced polyarthritis. The findings indicated that 2 or more genetic loci, as well as sex-related factors, played a major role in determining susceptibility to arthritis in this model. Breeding studies demonstrated that susceptibility was a dominant or codominant trait. A positive association between the severity of arthritis and the development of chronic inflammation in multiple tissues was also observed. In strains that were relatively resistant to arthritis, chronic inflammation was generally limited to the spleen. Since translocation of the poorly degradable and phlogogenic streptococcal cell walls to the synovium and other tissues appears to initiate inflammation, these studies suggested that susceptibility might be the result of a defect in host mechanisms limiting cell wall dissemination.
