Purpose: To evaluate whether the severity of interstitial lung abnormality (ILA), as indicated by quantitative computed tomographic (CT) indexes and CT visual score, was correlated with the stage and histological type of concurrent lung cancer. Materials and Methods: Twenty-eight patients with surgically diagnosed lung cancer and ILA on CT were enrolled in this retrospective study. The subjects were allocated to one of three groups by histological type: adenocarcinoma group (13 subjects);squamous cell carcinoma group (10 subjects);and the other histological diagnosis group (5 subjects). Two independent observers evaluated the CT findings to determine the CT visual score, and the kurtosis and skewness of CT-based density histograms were determined. The relationships between severity of ILA and the pathological stage and histological type of concurrent lung cancer were evaluated. Results: There were no significant differences in the CT visual scores and quantitative indexes among the three groups. CT visual score was significantly negatively correlated with pathological stage (r = −0.43, P = 0.025). Conclusion: Patients can have only mild ILA on visual scoring but advanced lung cancer. Therefore, the frequency of follow-up examination should not be based on the severity of ILA on CT.展开更多

The average age was 35.5 ±21.8y with a male-to-female ratio of 2.8:1. The most common age was 45-59 y age group. Most patients were farmers and workers(51.9%). The most common injuries were firework related(24.5%), road traffic related(24.2%), and work related(15.0%). Among the most common causative agents were firecrackers(24.5%), followed by metal/knife/scissors(21.4%). Most injuries occurred in January(14.2%),February(27.0%), and August(10.0%). There were 8.5%patients with ocular injuries combined with other injuries.The incidence of open ocular injuries(4585 eyes, 76.9%)was higher than closed ocular injuries(939 eyes, 15.7%).The incidences of chemical and thermal ocular injuries were 1.2% and 0.6%. Ocular trauma score(OTS)predicted final visual acuity at non light perception(NLP), 20/200-20/50 and 20/40 with a sensitivity of 100%,and light perception(LP) /hand motion(HM) and 1/200-19/200 with a specificity of 100%.· CONCLUSION: This study provides recent epidemiological data of patients hospitalized for ocular trauma in central China. Some factors influencing the visual outcome include time interval between injury and visit to the clinic, wound location, open or closed globe injury, initial visual acuity, and OTS.展开更多

The acceptable rate for PCR was 〈5%（lower limit h） and the unacceptable rate was 〉10%（upper limit h）. The acceptable rate for bestcorrected visual acuity worse than 20/40 was 〈10%（lower limit h） and the unacceptable rate was 〉20%（upper limit h）. The area between lower limit h and upper limit h is called the decision interval. RESULTS： There was no statistically significant difference in the mean age, sex or cataract grades between groups. The first trainee achieved PCR CUSUM competency at his 22 nd case. His best-corrected visual acuity CUSUM was in the decision interval from his third case and stayed there until the end, never reaching competency. The second trainee achieved PCR CUSUM competency at his 39^ th case. He could reach best-corrected visual acuity CUSUM competency at his 22 ^nd case. The third trainee achieved PCR CUSUM competency at his 41 st case. He reached bestcorrected visual acuity CUSUM competency at his 14 ^th case.CONCLUSION： The learning curve of competency in phacoemulsification is constructed by CUSUM and in average took 38 cases for each trainee to achieve it.展开更多

A secondary aim was to establish the evisceration rate for these injuries and assess how this form of intervention affected outcomes in comparison to the OTS.METHODSA prospective case series of all patients admitted with open globe injuries over a two-year (July 2009 to June 2011) period. Injuries were scored using the OTS and the surgical intervention was recorded. The best corrected visual acuity at three months was regarded as visual outcome.RESULTSThere were 249 open globe injuries, of which 169 patients (169 eyes) completed the 3-month follow-up. All patients underwent primary surgery, 175 (70.3%) repairs, 61 (24.5%) eviscerations and 13 (5.2%) other procedures. Globe eviscerations were mainly done on OTS Category 1 cases, but outcomes in this category were not found to be different from OTS outcomes. Outcomes were significantly worse in Category 2, but when the entire distribution was tested, the differences were not statistically significant. The overall association between OTS outcomes and the final visual outcomes in this study was found to be a strong (P<0.005).CONCLUSIONReliable information regarding the expected outcomes of eye injuries will influence management decisions and patient expectations. The OTS is a valuable tool, the use of which has been validated in many parts of the world-it may also be a valid predictor in an African setting.展开更多

They were further examined for any kind of co-morbidities because of trauma, operated upon for traumatic cataracts with intraocular lens implantation. Amblyopia if present was treated. All were re-examined at the culmination of six-week postoperative period.According to the Birmingham Eye Trauma Terminology System the traumatic cataract cases were divided into group 1(open globe) and group 2(closed globe), and then determinants of visual acuity were compared.RESULTS: There were 544 eyes in group 1 and 127 eyes in group 2 in our study of 671 eyes with pediatric traumatic cataracts. Visual acuity at the end of 6 wk after surgery in the operated eye was > 6/60 in 450(82.7%) and ≥ 6/12 in 215(39.4%) eyes in the open globe group and > 20/200 in 127(81.8%) and ≥ 6/12 in 36(28.4%) eyes in the closed globe group(P = 0.143), and the difference between the groups was not significant in children. Overall, 402(39.4%) eyes gained ≥ 6/60 and > 5/12 in 238(35.4%) cases. Surgical treatment caused a significant difference in visual outcome(P = 0.000). When we compared achieved visual outcome with ocular trauma score predicted vision, no significant difference was found.CONCLUSION: Traumatic cataracts in children may have better outcome and ocular trauma score is a useful predictive method for the ocular trauma in children.展开更多

In t...Objectives: “Patient-reported outcome measures” has been used extensively, and it has shown the diseases’ impact on patient quality of life and has enabled the clinician to evaluate the clinical care efficacy. In the literature, there are more than 34 shoulder function assessment scoring instruments;the Modified Constant Murley Score (M-CMS) is one of the most popular scores. Although, the M-CMS had been translated and culturally adapted to Danish, Brazilian and Turkish versions, there is no Arabic version found in the literature. We aim to translate and culturally adapt M-CMS into the Arabic language. Method: The M-CMS was translated using previously published guidelines. The translation and cultural adaptation were done in five stages, initial translation by two bilingual translators then a synthesis of the translations after that, back translation by two native English speakers. Then an expert committee meeting approved the pre-final Arabic version. Finally, a pilot test was conducted on 41 patients to ensure its validity. Results: The M-CMS was successfully translated from the original English version to the Arabic version;no difficulties in the translation process were faced. Conclusion: A validated Arabic version of the M-CMS was produced and ready to be used for functional assessment of different shoulder pathologies in Arabic-speaking countries. Future study is needed for translation and cultural adaptation of the English standardized test protocol to assure the reproducibility of the Arabic version of the M-CMS.展开更多
