Xeroderma pigmentosum (XP) is a rare autosomal recessive disorder that has been found in all continents and racial groups in relation to faulty repair of DNA with sun exposure. Several cutaneous and ocular tumors have been described in relation to XP including fibrous histiocytoma (FH). The diagnosis of conjunctival FH is challenging owing to the rarity of this tumor and the diversity of its classification into benign, locally aggressive and malignant. We are describing a recurrent FH exhibiting a locally aggressive behavior in a child with history of XP. Detailed histopathological features are presented with literature review. 相似文献

Introduction
Previous data examining the effect of gender on surgical trainee autonomy is lacking. We hypothesized that female general surgery residents have less autonomy than males during laparoscopic cases.Methods
We retrospectively reviewed factors associated with level of guidance needed during laparoscopic procedures as reported on intraoperative procedure feedback forms and on FLS tasks from one institution from 2013 to 2016. Data collected included resident and attending gender, level of guidance needed, PGY level, case characteristics, resident intraoperative performance, and skills lab FLS performance. Univariate and multivariate analyses were performed using a mixed-effects regression model.Results
We analyzed data from 106 PGY1-PGY5 residents (51% Female) and 104 attendings (26% Female). Female resident gender was associated with more intraoperative guidance in univariate (p?=?0.019) and multivariate analysis (p?=?0.034). Technical performance between genders was similar.Conclusions
This study demonstrated gender-based inequality in intraoperative autonomy even after controlling for technical performance, PGY level, and case factors. 相似文献107.

PurposeThe aim of this study is to identify burnout prevalence among ophthalmology residents and the predisposing factors associated with higher levels of burnout.MethodsA cross-sectional study was conducted on all ophthalmology residents in Saudi Arabia using Maslach Burnout Inventory in January 2018. Associations between Emotional Exhaustion scores and other continuous variables were evaluated using Spearman’s correlation coefficients. Logistic regression model was constructed, and results were reported as odds ratios with 95% confidence intervals. The significance level was set at p < 0.05.ResultsA total of 117 residents responded to the survey with a 70% response rate. The response rate was above 65% for each training programs by region. 41% of ophthalmology residents scored a positive burnout result on the common subscales (Emotional Exhaustion and/or Depersonalization). Further sub-analysis of data showed positive Spearman’s correlation with number of call days per month and EE subscale (r 0.195). Multivariate logistic regression of the sample yielded significant results with satisfaction with work/life balance and choosing medicine again as a graduate level major p ≤ 0.05. The regression model also showed the Southern program had significantly higher burnout on the common subscales p ≤ 0.05.ConclusionsPrevalence of burnout among ophthalmology residents was lower when compared to plastic surgery and otolaryngology residents in Saudi Arabia. Work hours and on call days were associated with higher burnout. Actions must be taken to ensure that all training programs implement work hour limitations. Special attention should be given to the Southern region program due to its significantly higher levels of burnout. 相似文献
