Learning points: Cushing's syndrome can present in many ways, a high index of suspicion is required for its diagnosis, as often patients present with only few of the pathognomonic symptoms and signs of the syndrome.Proximal lower-limb girdle myopathy is common in Cushing's syndrome. Less often long-term exposure of excess glucocorticoid production can also affect other muscles including respiratory muscle and the diaphragm leading to progressive shortness of breath and even acute respiratory failure.Treatment of Cushing's myopathy involves treating the underlying cause that is hypercortisolism. Various medications have been suggested to hinder the development of GC-induced myopathy, but their effects are poorly analysed.
STUDY DESIGN: This is a cross-sectional study.
METHODS: This study was completed alongside similar studies undertaken by the rest of the Gulf Cooperation Council (GCC) countries and led by Kingdom of Saudi Arabia (KSA). The study will allow further understanding of possible obstacles that may be encountered while implementing a nationwide prevention program. The 10-dimensional model of readiness had been developed by the World Health Organization (WHO) in collaboration with five countries (Brazil, The Former Yugoslav Republic of Macedonia, Malaysia, Saudi Arabia, and South Africa) through a five-stage process. Stakeholders and decision makers were invited to participate. Scores for each dimension were compared with those for the rest of the GCC countries.
RESULTS: The overall score of Kuwait was 39.17 out of 100. This was below the mean average score for the GCC countries (47.83). Out of the 10 dimensions, key informants scored the highest on legislation, mandates and policies (6.61). The lowest score was reported on attitudes towards CM prevention (1.94). Informal social resources (5.72) ranked the highest as compared to the rest of the GCC countries.
CONCLUSIONS: The readiness of Kuwait is weak on several dimensions and needs to be strengthened. Despite that, the country is moderately ready to implement large-scale evidence-based CM prevention programs because it is strong in the infrastructure of knowledge, legislation, mandates, and policies and informal social resources.
METHODS: A three-dimensional structure of graphene hydrogel was prepared via a simple hydrothermal method using two-dimensional large-area graphene oxide nanosheets as a precursor.
RESULTS: The concentration and lateral size of the graphene oxide nanosheets influenced the structure of the hydrogel. With larger-area graphene oxide nanosheets, the graphene hydrogel could be formed at a lower concentration. X-ray diffraction patterns revealed that the oxide functional groups on the graphene oxide nanosheets were reduced after hydrothermal treatment. The three-dimensional graphene hydrogel matrix was used as a scaffold for proliferation of a MG63 cell line.
CONCLUSION: Guided filopodia protrusions of MG63 on the hydrogel were observed on the third day of cell culture, demonstrating compatibility of the graphene hydrogel structure for bioapplications.
Materials and Methods: We reviewed prospectively collected data in our tertiary hospital arthroplasty registry and identified patients who underwent revision THA between 2001 and 2014, with a minimum of two years follow-up. The study group (two-stage revision THA for PJI) consists of 23 patients and the control group (one-stage revision THA for aseptic reasons) consists of 231 patients. Patient demographics, Western Ontario and McMaster Universities Arthritis Index (WOMAC), Oxford Hip Score (OHS), Short Form-36 (SF-36) scores and patient reported satisfaction were evaluated. Student's t-test was used to compare continuous variables between the two groups. Statistical significance was defined as p <0.05.
Results: The pre-operative demographics and clinical scores were relatively similar between the two groups of patients. At two years, patients who underwent revision THA for PJI reported a better WOMAC Pain Score and OHS as compared to aseptic revision THA. A similar proportion of patients were satisfied with their results of surgery in both groups (p=0.093).
Conclusions: Although patients who underwent revision THA for PJI had poorer pre-operative functional scores (WOMAC function and SF-36 PF), at two years follow-up, these two groups of patients have comparable post-operative outcomes. Interestingly, patients who had revision THA for PJI reported a better clinical outcome in terms of OHS and WOMAC Pain score as compared to the aseptic group. We conclude that the revision THA for PJI is not inferior to aseptic revision THA in terms of patient satisfaction and clinical outcomes.
