We noted an earlier age at presentation of malignant tumors. Mature teratoma was found to be the second most common benign tumor (after serous cystadenoma). We also noted a lower percentage of endometrioid tumors. Lower number of stage IV tumors was noted, with a significant number of malignant ovarian tumors presenting at an earlier age.

Background:The Bethesda system for reporting thyroid cytopathology represents a major step towards standardization, reproducibility, improved clinical significance, and greater predictive value of thyroid fine needle aspirates (FNAs).Aims:To elucidate the utility of the Bethesda system in reporting thyroid FNAs.Materials and Methods:We retrospectively reviewed thyroid FNAs between April 2009 and March 2012, classified them using the Bethesda system, found out the distribution of cases in each Bethesda category, and calculated the malignancy risk for each category by follow-up histopathology.Results:Of the 1020 FNAs, 1.2% were non-diagnostic, 87.5% were benign, 1% were atypical follicular lesion of undetermined significance (AFLUS), 4.2% were suspicious for follicular neoplasm (SFN), 1.4% were suspicious for malignancy (SM), and 4.7% malignant. Of 69 cases originally interpreted as non-diagnostic, 12 remained non-diagnostic after re-aspiration. In 323 cases, data of follow-up histopathologic examination (HPE) were available. Rates of malignancy reported on follow-up HPE were non-diagnostic 0%, benign 4.5%, AFLUS 20%, SFN 30.6%, SM 75%, and malignant 97.8%.Conclusions:Reviewing the thyroid FNAs with the Bethesda system allowed a more specific cytological diagnosis. In this study, the distribution of cases in the Bethesda categories differed from some studies, with the number of benign cases being higher and the number of non-diagnostic and AFLUS cases being lower. The malignancy risk for each category correlated well with other studies. The Bethesda system thus allows standardization in reporting, improves perceptions of diagnostic terminology between cytopathologists and clinicians, and leads to more consistent management approaches.

In the present study, we report the aqueous extract of Pithophora oedogonia to produce silver nanoparticles (AgNPs) by reduction of silver nitrate. It was noted that synthesis process was considerably rapid and silver nanoparticles were generated within few minutes of silver ions coming in contact with the algal extract. A peak at 445 nm corresponding to the plasmon absorbance of AgNPs was noted in the UV-vis spectrum of the aqueous medium that contained silver ions. Scanning electron microscopic (SEM) and dynamic light scattering analysis of colloidal AgNPs indicated the size of 34.03 nm. Energydispersive X-ray spectroscopy revealed strong signals in the silver region and confirmed of the AgNPs. Fourier transform infrared spectroscopic analysis of the nanoparticles indicated the presence of protein which was regarding a capping agent surrounding the AgNPs. Moreover, the antibacterial activity of synthesized nanoparticles exhibited potential inhibitory activity against seven tested pathogenic bacteria.

Gross anatomy instruction in medical curricula involve a range of resources and activities including dissection, prosected specimens, anatomical models, radiological images, surface anatomy, textbooks, atlases, and computer-assisted learning (CAL). These resources and activities are underpinned by the expectation that students will actively engage in self-directed study (SDS) to enhance their knowledge and understanding of anatomy. To gain insight into preclinical versus clinical medical students' preferences for SDS resources for learning gross anatomy, and whether these vary on demographic characteristics and attitudes toward anatomy, students were surveyed at two Australian medical schools, one undergraduate-entry and the other graduate-entry. Lecture/tutorial/practical notes were ranked first by 33% of 156 respondents (mean rank ± SD, 2.48 ± 1.38), textbooks by 26% (2.62 ± 1.35), atlases 20% (2.80 ± 1.44), videos 10% (4.34 ± 1.68), software 5% (4.78 ± 1.50), and websites 4% (4.24 ± 1.34). Among CAL resources, Wikipedia was ranked highest. The most important factor in selecting CAL resources was cost (ranked first by 46%), followed by self-assessment, ease of use, alignment with curriculum, and excellent graphics (each 6-9%). Compared with preclinical students, clinical students ranked software and Acland's Video Atlas of Human Anatomy higher and felt radiological images were more important in selecting CAL resources. Along with other studies reporting on the quality, features, and impact on learning of CAL resources, the diversity of students' preferences and opinions on usefulness and ease of use reported here can help guide faculty in selecting and recommending a range of CAL and other resources to their students to support their self-directed study.

Background:Fibroadenomas and phyllodes tumors may have similar cytological appearances. However, a detailed study of cytomorphology of stromal elements may be helpful in differentiation.Aim:To evaluate the cytological features of phyllodes tumor in our study with special reference to features that can help distinguishing it from fibroadenoma.Materials and Methods:The archival materials of our hospital were searched from January 2006 to January 2009 for histopathologically-diagnosed cases of phyllodes tumor. The cases in which previous cytopathology smears were available were included in the study. The cytomorphology of 10 such cases were compared with 25 cytologically-diagnosed and histopathologically-confirmed cases of fibroadenoma.Results:The size, cellularity of stromal fragments, and the proportion of spindle cells in the background are important features in such differentiation.

Randomised controlled trials represent the gold standard in intervention efficacy evaluation. However, suboptimal recruitment affects completion and the power of a therapeutic trial in detecting treatment differences. We conducted a systematic review to examine the barriers and enablers to patient recruitment for randomised controlled trials on chronic wound treatment. Review registration was under PROSPERO 2017:CRD42017062438. We conducted a systematic search of Ovid MEDLINE, EBSCOhost CINAHL, Ovid Cochrane Library, Ovid EMBASE, and Ovid PsycINFO databases in June 2017 for chronic wound treatment randomised controlled trials. Twenty-seven randomised controlled trials or qualitative studies met the inclusion criteria. Among the 24 randomised controlled trials, 21 were assessed as low quality in relation to recruitment, and 3 were assessed as high quality. All 27 studies reported barriers to recruitment in chronic wound randomised controlled trials. The reported barriers to recruitment were: study-related, patient-related, clinician-related, health system-related, and/or operational-related. No study reported recruitment enablers. To enhance randomised controlled trial recruitment, we propose the need for improved integration of research and clinical practice. To alleviate the problems arising from inadequate reporting of randomised controlled trials, the Consolidated Standards of Reporting Trials Statement could include an additional item on recruitment barriers. This approach will allow for increased awareness of the potential barriers to recruitment for Randomised controlled trials (RCTs) in both wound management and other health care research.

Amiodarone-associated thyrotoxicosis may be severe and refractory to medical therapy. Despite the potential risks of anaesthesia associated with uncontrolled thyrotoxicosis, thyroidectomy should be considered in the setting of life-threatening thyrotoxicosis.
