RESUMO

OBJECTIVES: To investigate the knowledge, attitudes practices and perceptions of clinicians concerning the conducting of clinical trials (CTs).  Methods: A cross-sectional study was conducted on clinicians at King Fahad Medical City, Riyadh, Saudi Arabia. Data were collected using a self-administered questionnaire which divided into 5 sections: Section 1 covered respondents' demographics. The other 4 sections explored respondents' knowledge, attitudes, perceptions and practice towards conducting CTs.  Results: A total of 316 clinicians completed the questionnaire. The majority were assistant consultants and consultants 125 (39.5%) and 108 (34.2%), respectively. One hundred sixty-nine (56%) respondents were not aware of the Declaration of Helsinki at all. Two hundred seventy-five (88.4%) respondents expressed interest in conducting CTs and 61.7% and participants showed their willingness to facilitate and assist in CTs conducted by other clinicians. Moreover, 112 (35.9%) respondents participated in CTs previously. Regarding the disadvantages in conducting CTs, participants indicated that the paperwork was complicated and they believed that they might lose patients from their clinical practice once they are recruited in CTs. Lack of research protected time for clinicians 295 (97.7%), and a shortage of clinical research coordinators 293 (97%) were the main problems reported by respondents.  Conclusions: Although the majority of participants had an unsatisfactory level of knowledge and misperceptions about CTs, they showed an interest in and positive attitudes about conducting CTs.

RESUMO

We report a rare case of bilateral keratoconus in association with achondroplasia. A 26-year-old male, with a known case of achondroplasia, complained of bilateral gradual deterioration in vision for the past few years. Slit lamp biomicroscopy showed bilateral central corneal protrusion and stromal thinning at the apex consistent with keratoconus. a trial of hard contact lens fitting failed to improve VA in the left eye (LE). Right eye (RE) improved to 20/25. The patient underwent penetrating keratoplasty (PKP) in his LE. Twenty-seven months postoperatively, uncorrected visual acuity (UCVA) was 20/30. Ophthalmologists should be aware that patients with achondroplasia who complain of poor vision should be suspected of having keratoconus once other more common conditions are ruled out.

RESUMO

OBJECTIVE: To apply the updated epithelial salivary gland classification scheme to a large cohort of lacrimal gland tumors so as to provide an updated lacrimal gland tumor classification scheme. METHODS: A retrospective multicenter cohort study of 118 cases of epithelial neoplasia was undertaken. Main outcome measures included pathologic analysis, subtyping, and survival. RESULTS: Of 118 cases, 17 (14%) were reclassified using the proposed expanded classification scheme based on the current World Health Organization classification of salivary gland tumors. The most frequent neoplasms were pleomorphic adenoma and adenoid cystic carcinoma, of which we highlight more unusual histologic features. Three tumors were found to be unclassifiable with the updated scheme, with 2 having histologically malignant features. Deficiencies and variations in pathologic assessment were noted. Variation in the histologic findings of pleomorphic adenoma and assessment of the extent of invasion of carcinoma ex pleomorphic adenoma were highlighted. CONCLUSIONS: The use of the more histologically diverse classification of salivary gland tumors can be successfully applied to the epithelial lacrimal gland neoplasms. This expanded classification system led to reclassifying 14% of cases. Currently, there are no consistent pathologic standards for processing and evaluating these lesions.
