RESUMO

OBJECTIVES: Studies show limited improvement in the frequency of engaging in life activities after joint replacement. However, there is a paucity of research that has examined factors, including other life events, which influence engagement following total hip replacement (THR). This research sought to identify factors associated with engaging in life activities following THR. METHODS: A prospective cohort study was conducted with 376 people who had a THR for osteoarthritis (OA). Data were collected pre-surgery and 1 year post-surgery. The primary outcome was change in frequency in engagement in life activities (Late Life Disability Index (LLDI): higher scores indicate higher frequency of engagement (range 0-80)). Analyses included multivariable regression. Factors considered included: positive/negative life events, a new comorbidity, another joint replacement and complications post-surgery. RESULTS: Participants' mean age was 64 years; 46% were male. 68% of participants had at least one comorbidity pre-surgery; 36% reported at least one new comorbidity after surgery. The mean change in LLDI frequency was an increase of 6.29 (±8.10). 36% reported one or more positive impact life events in the year following surgery; 63% reported one or more negative life events. The number of positive life events (beta = 1.24; 95% CI: 0.49, 1.99) was significantly associated with change in LLDI frequency after adjusting for age, sex, education, body mass index (BMI), comorbidities pre-surgery, number of symptomatic joints and pre-surgery pain and function, LLDI limitations and depression. CONCLUSIONS: These findings highlight the significant influence of social factors and life circumstances on engagement in life activities following THR.

RESUMO

OBJECTIVE: To evaluate the internal consistency and construct validity of the Physical Function short-forms for the Hip and Knee Injury Osteoarthritis Outcome Scores (HOOS-PS/KOOS-PS) and the Intermittent and Constant Osteoarthritis Pain (ICOAP) in a nine country study of patients consulting for total hip or knee replacement (THR or TKR). METHODS: Patients completed HOOS-PS or KOOS-PS, ICOAP and Western Ontario and McMaster Universities' Osteoarthritis Index (WOMAC) pain and physical function subscales at their consultation visit. Internal consistency was calculated using Cronbach's alpha. The association of HOOS-PS/KOOS-PS and ICOAP with WOMAC pain and function subscales was calculated with Spearman correlation coefficients with 95% confidence intervals. RESULTS: HOOS-PS/KOOS-PS and ICOAP demonstrated high internal consistency across countries (alpha 0.75-0.96 (hip) and 0.76-0.95 (knee)). Both HOOS-PS and KOOS-PS demonstrated high correlations (0.76-0.90 and 0.75-0.91, respectively) with WOMAC function in all countries. ICOAP exhibited moderate to high correlations with WOMAC pain and function subscales (0.53-0.84 (hip) and 0.43-0.84 (knee)). CONCLUSION: The psychometric properties of the HOOS-PS/KOOS-PS, and ICOAP were maintained across all countries.

RESUMO

OBJECTIVE: Numerous studies report large and significant improvements in basic mobility and activities of daily living following total hip or knee replacement (TJR). Nevertheless, quantitative research has shown minimal increase in participation in activities that benefit overall health. This study explored why people do or do not engage in activities following hip or knee TJR. METHOD: This was a longitudinal qualitative study. Sampling was guided by constructivist grounded theory and data collected using open-ended, semi-structured interviews. Participants were recruited using maximum variation sampling based on age, sex and joint replaced (hip or knee). Data were analysed using a constant comparative approach and coded for thematic patterns and relationships from which overarching themes were constructed. RESULTS: Twenty-nine patients participated in interviews prior to, and 8 and 18 months post following TJR. A high degree of variability with regard to participants' return to activities was found and five emergent themes were identified that accounted for this variability. These themes highlight the importance of issues beyond medical factors alone, such as socio-cultural factors that partially determine participants' participation in activity following TJR. CONCLUSION: Findings suggest that multi-faceted experiences impact participation in activity following TJR. These experiences include changes in identity and lifestyle that preclude a 'return to normal'. There is an urgent need for supports to increase people's activity post-TJR in order to facilitate enhancement of post-surgery levels of engagement. Approaches that take into consideration more personalized interventions may be critical to promoting healthy aging in people with TJR.

RESUMO

OBJECTIVE: Little is known about the relationships among pain, function, psychological variables like perceived helplessness and emotional health, and patient satisfaction in people with revision knee replacement surgery. We hypothesized that pain and function would have a direct association with satisfaction as well as an indirect association through patient perceptions of helplessness and emotional health. DESIGN: This longitudinal study included 145 participants undergoing revision knee replacement surgery. Demographic data and expectation of benefit from surgery were recorded prior to surgery. The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), the Arthritis Helplessness Scale (AHS) and the Mental Component Scale (MCS) of the SF-36 (emotional health) were collected prior to and 2 years post-surgery. Satisfaction was recorded 2 years post-surgery. Regression analyses were conducted to test for mediation effects of helplessness and MCS. RESULTS: Participants were on average 69 years old and 54% were women. Participants were satisfied with the results of the surgery (mean ± standard deviation (SD) = 70.42 ± 31.46). Less pain and functional disability were associated with increased patient satisfaction and, the effect of pain or function was also mediated through helplessness whereby more pain and disability were associated with perceptions of helplessness and helplessness was associated with lower satisfaction. MCS did not mediate the relationship of pain and function with satisfaction. CONCLUSION: Helplessness plays an important role in understanding patient satisfaction. Interventions aimed at improving patient outcome should target not only pain and function but also should address strategies to support people in managing following knee revision surgery to maximize satisfaction with outcome.

RESUMO

OBJECTIVE: The Intermittent and Constant Osteoarthritis (OA) Pain (ICOAP) questionnaire evaluates the constructs of 'intermittent'(tm) and 'constant'(tm) pain. Theses are conceptually different from 'pain on activity'(tm) and pain 'intensity'(tm) as measured by the WOMAC and Chronic Pain Grade (CPG), measures commonly used in OA. The purpose of this study was to evaluate the responsiveness of the ICOAP, and different pain constructs in primary total hip (THR) and total knee (TKR) replacement. METHODS: Patients completed the ICOAP, WOMAC and HOOS/KOOS pain and the CPG pre- and 6 months post surgery. Scores were standardized to 0 to 100, where higher scores indicate worse pain. Descriptive statistics were calculated for all data. The standardized response mean (SRM) was calculated for each measure as were correlations of change scores. RESULTS: The THR group (n = 34) ranged in age from 37-85 years with 74% male. The TKR group (n = 44) ranged in age from 45-86 years with 75% female. Both groups had significant improvement (p < .0001) on all pain measures but the TKR group had smaller improvements. For THR, the SMR was 1.50, 2.31 and 2.29 for constant, intermittent and total scores and for TKR, was 0.84, 1.02 and 1.02 respectively. The SMR ranged from 2.05 to 2.99 for the other measures for THR and from 1.13 to 1.44 for TKR patients. Correlations of the change scores were ranged from 0.26 to 0.81. CONCLUSION: Multi-faceted constructs of pain are effectively relieved through joint replacement and all measures including the ICOAP demonstrated responsiveness.

RESUMO

BACKGROUND: Accurate measurement of retinal nerve fiber layer (RNFL) is now possible with the high resolution optical coherence tomography (OCT). Effect of refractive status of the eye on RNFL thickness may be relevant in the diagnosis of glaucoma and other optic nerve diseases. AIM: To assess the RNFL thickness and compare its correlation with refractive status and axial length of the eye. MATERIAL AND METHODS: Three hundred eyes of 150 patients were included in this study, who underwent RNFL analysis using TOPCON 3D OCT 2000. Analysis of variance has been used to find the significance of study parameters between the study groups. RESULTS: The study showed that refractive status/axial length affected the peripapillary RNFL thickness significantly. CONCLUSION: The study suggests that the diagnostic accuracy of OCT may be improved by considering refractive status and axial length of the eye when RNFL is measured.

RESUMO

BACKGROUND: With the emergence of multidrug-resistant (MDR-) and extensively drug-resistant tuberculosis (XDR-TB), surgery, which had been replaced by short-course chemotherapy, is again being considered a viable treatment option. OBJECTIVE: To assess the literature on the effectiveness of surgical interventions in the treatment of drug-resistant TB. METHODS: Medline, EMBASE, and PubMed were searched from 1975 to April 2012 in addition to hand searching reference lists, and the International Journal of Tuberculosis and Lung Disease. Potentially relevant studies were assessed according to pre-defined eligibility criteria: MDR- and XDR-TB patients undergoing surgical and non-surgical treatment. Treatment outcomes were extracted according to internationally accepted definitions and included in meta-analyses using random effects models. RESULTS: Summary meta-analysis of 24 comparison studies revealed a significant association between surgery and successful treatment compared to non-surgical interventions (OR 2.24, 95%CI 1.68-2.97). A meta-analysis from 23 single-arm studies demonstrated that respectively 92% (95%CI 88.1-95) and 87% (95%CI 83-91) of surgical patients achieved successful short- and long-term outcomes. Subgroup analyses showed that favorable surgical outcomes were associated with increased drug resistance in studies reporting surgical and non-surgical treatment outcomes. CONCLUSIONS: While the results suggest that surgical intervention is associated with successful treatment outcomes in patients with drug-resistant TB, there is insufficient evidence to recommend surgery plus chemotherapy over chemotherapy alone, to evaluate the potential harm from surgery and to determine the optimal conditions for surgery. Controlled studies are needed to better assess the effectiveness of surgery and to investigate other contextual issues.

RESUMO

Trachoma is one of the leading causes of blindness and clinical examination remains the mainstay of diagnosis. However there is need to evaluate simple, inexpensive techniques which can be used for screening of trachoma in endemic regions. We report two cases where conjunctival impression cytology played a part in confirming the diagnosis of trachoma. We used a modified technique of obtaining conjunctival impressions, which not only met with better patient compliance and minimal ocular distress, but also provided better cellularity and morphology of cells for evaluation. The impression smears showed squamous metaplasia and loss of goblet cells. The cytoplasm of these cells had a hazy, moth eaten appearance and showed presence of intracytoplasmic inclusions. These basophilic inclusions were present singly and in clusters and were around 5 mum in diameter. A large number of these inclusions were present extracellularly as well. Conjunctival impression cytology is a simple procedure which needs to be evaluated for its potential to be used for screening trachoma in endemic areas.
