RESUMO

We report a rare case of a suspected inflammatory reaction to stored fascia lata 37 years post-placement. Clinical, imaging, histopathological, and immunohistochemical findings are presented, with a literature review on reactions to stored fascia lata. A 39-year-old woman had upper eyelid congenital ptosis repaired successfully at 2 years with bilateral frontalis suspension procedures using stored fascia lata. Thirty-seven years later, the patient presented with swelling of her eyelids and forehead, which was tender to the touch, in the same pattern as the fascia lata slings placed earlier. Histopathological examination disclosed a non-necrotizing granulomatous inflammatory infiltrate with numerous asteroid bodies. Initially, it was responsive to oral prednisone, but with recurrent inflammation, long-term methotrexate was required to control the inflammation. To our knowledge, this type of delayed inflammatory reaction has not been previously reported. It raises a concern about the use of allogeneic donor tissue and accepted sterilization techniques that may not be 100% effective in deactivating all components of the donor graft, including potential infectious pathogens, leading to a subsequent latent reaction.

RESUMO

PURPOSE: To report a case of subjective intermittent loss of bilateral colour vision and episodic white-out vision in a patient with undiagnosed chronic myeloid leukemia (CML). OBSERVATIONS: A patient initially diagnosed with diabetic retinopathy presented with a chief complaint of subjective intermittent loss of colour vision in both eyes, as well as intermittent bilateral white-out vision. These symptoms previously went uninvestigated until a thorough history revealed concurrent constitutional symptoms including recent night sweats and fevers. Closer fundus examination revealed that the lesions previously thought to be diabetic retinal hemorrhages were Roth spots. CONCLUSIONS AND IMPORTANCE: An unusual chief complaint of colour vision loss and multiple Roth spots in the context of chronic night sweats and fevers prompted further workup. A CBC with differential revealed a markedly increased WBC count and the patient was diagnosed with CML. Cytoreduction therapy led to complete resolution of the patient's visual symptoms and a return to normal WBC count at the most recent follow up appointment. We report, to our knowledge, the only case of colour vision loss as the initial presenting symptom of CML in the current literature, and reiterate the importance of a thorough history, neuro-ophthalmic examination and relevant investigations in patients with unusual visual symptoms, including intermittent loss of colour vision. In this case, we speculate that hyperviscosity syndrome secondary to CML was the cause of this patient's peculiar visual disturbance.

RESUMO

PURPOSE: The study sought to evaluate application trends in Canadian diagnostic radiology residency programs and to assess the relative competitiveness of radiology as a specialty. METHODS: The Canadian Residency Matching Service Reports from 1991-2014 for Canadian graduates were used to extract the total residency positions and radiology residency positions, number of applicants to all specialties and to radiology, number of first-choice radiology applicants, number of unmatched radiology positions, and number of positions and applicants to each specialty. Ratios were calculated: radiology positions to applicants and first-choice applicants, first-choice radiology applicants to applicants for all specialties, and training positions to applicants in each specialty. Data trends and correlation coefficients were analysed. RESULTS: The number of radiology residency positions offered increased, with strong positive correlation (r = 0.91, P < .001), while the number of applicants increased with only a moderate positive correlation (r = 0.49, P = .03). Radiology was the most competitive in 1997, with a ratio of 0.32 positions/applicant. There was an increase of positions/applicant over time (decreasing competitiveness; r = 0.76, P < .001) but no change in positions/first-choice applicant (r = 0.11, P = .65). The highest percentage of applicants who ranked radiology as their first choice was in 2003 at 6.5% with a decrease in this percentage over time (r = -0.36, P = .13). Radiology is moderately competitive for positions/overall applicants and very competitive for positions/first-choice applicants compared to other specialties. CONCLUSIONS: The number of radiology residency positions has increased while the number of applicants has not grown commensurately. The match was most competitive in 1997, and decreased in subsequent years. Possible reasons include job market, reimbursement, and work environment.

RESUMO

BACKGROUND: Resident selection committees must rely on information provided by medical schools in order to evaluate candidates. However, this information varies between institutions, limiting its value in comparing individuals and fairly assessing their quality. This study investigates what is included in candidates' documentation, the heterogeneity therein, as well as its objective data. METHODS: Samples of recent transcripts and Medical Student Performance Records were anonymised prior to evaluation. Data were then extracted by two independent reviewers blinded to the submitting university, assessing for the presence of pre-selected criteria; disagreement was resolved through consensus. The data were subsequently analysed in multiple subgroups. RESULTS: Inter-rater agreement equalled 92%. Inclusion of important criteria varied by school, ranging from 22.2% inclusion to 70.4%; the mean equalled 47.4%. The frequency of specific criteria was highly variable as well. Only 17.7% of schools provided any basis for comparison of academic performance; the majority detailed only status regarding pass or fail, without any further qualification. CONCLUSIONS: Considerable heterogeneity exists in the information provided in official medical school documentation, as well as markedly little objective data. Standardization may be necessary in order to facilitate fair comparison of graduates from different institutions. Implementation of objective data may allow more effective intra- and inter-scholastic comparison.

RESUMO

PURPOSE: To evaluate whether completeness of reporting of systematic reviews and meta-analyses in major radiology journals has changed since publication of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement; a secondary objective is to evaluate whether completeness of reporting (ie, PRISMA) is associated with study quality (ie, Assessing the Methodological Quality of Systematic Reviews [AMSTAR]). MATERIALS AND METHODS: Systematic reviews and meta-analyses published in major radiology journals between January 2007 and December 2011 were identified by searching MEDLINE with the modified Montori method. Studies were reviewed independently by two investigators and assessed for adherence to the AMSTAR and PRISMA checklists. The average results were analyzed to assess for change in mean score before and after PRISMA publication and to assess results over time; a Pearson correlation coefficient was calculated to assess for any association between PRISMA and AMSTAR results. RESULTS: Included were 130 studies from 11 journals. Average PRISMA and AMSTAR results were 21.8 of 27 and 7.2 of 11, respectively. The average result was higher after publication of PRISMA, and PRISMA-reported items were 22.6 of 27 after publication of PRISMA versus 20.9 of 27 before publication of PRISMA; AMSTAR results were 7.7 of 11 after publication of PRISMA versus 6.7 of 11 before publication of PRISMA. There was a strong positive correlation (r = 0.86) between the PRISMA and AMSTAR results. There was high variability between journals. Radiology had the highest PRISMA reported items (24.7 of 27), and American Journal of Neuroradiology had the lowest (19.6 of 27). Two major areas for improvement include study protocol registration and assessment of risk of bias across studies (ie, publication bias). CONCLUSION: In major radiology journal studies, there was modest improvement in completeness of reporting of systematic reviews and meta-analyses, assessed by PRISMA, which was strongly associated with higher study quality, assessed by AMSTAR.
