Validity of Medical Students Self-Assessment of Proficiency in Clinical Long Case Examination

@#Introduction: Self-assessment is a mechanism to evaluate one’s own performance and identify strengths and weaknesses. However, there is paucity of information on the the validity of self-assessment in the literature. This study is planned to assess the validity of medical students’ self-assessment skills in clinical examinations with long case during their postings in Obstetrics and Gynaecology. Methods: A cross sectional study was conducted during Obstetrics and Gynaecology (O&G) rotation assessing the students performance in the clinical long case examination. Participants were 80 fourth year medical students who were in their last week of their O&G rotation between August and December 2019. Each student was given a random case from the obstetric ward for the clinical long case examination during their final week of posting. At the end of examination, both student and examiner were tasked to independently evaluate the performance with a standardized grading sheet. Students were assessed in three areas namely Case Presentation (4 items), Case Discussion (4 items) and Professionalism and Overall approach to the practice of medicine (2 items). Results: The correlation coefficient was identified to be 0.307, p<0.01, indicating validity in self-assessment in the context of a clinical examination. The overall bias index was -0.97. Students underrated themselves in all areas with bias indexes of -0.35 in case presentation, -0.26 for case discussion and -0.35 in the professionalism and overall approach to practice. The correlation coefficients were 0.186, 0.360 and 0.170 respectively, indicating that in isolation only the component of case discussion showed significant correlation (p<0.01). Conclusion: Self-assessment in clinical examination is shown to be a valid assessment method when multiple assessment items are combined.

Clinical Assessment Limitation in Extragastrointestinal Stromal Tumour of Rectovaginal Septum Diagnosis: A Case Report

@#Extragastrointestinal tumour of rectovaginal septum (rvGIST) is a rare malignancy that affects rectovaginal septum. We present a case of rvGIST that was initially managed as cervical eGIST based on clinical assessment. A 66-yearold woman presented with postmenopausal bleeding and constipation. Bimanual pelvic examination revealed an irregular mass occupying the vagina. CT thorax, abdomen and pelvis showed a 9.2 x 10.0 x 14.0 cm pelvic mass arising from cervix, extending superiorly to involve the uterus. The patient proceeded to undergo total abdominal hysterectomy, bilateral salpingo-oophorectomy, enucleation of rectovaginal septum mass, rectosigmoidectomy and permanent colostomy. Intraoperatively, there was a 9 x 7 cm mass arising from rectovaginal septum. Histopathological examination of surgical specimen revealed spindle cell tumour diffusely positive for CD34, CD117 and DOG1. The final diagnosis was rvGIST. In conclusion, the diagnosis of rvGIST require a combination of clinical assessment with intraoperative finding and histological assessment of the surgical specimen.

Role of microRNAs as biomarkers of cervical carcinogenesis: a systematic review

We performed a systematic review to identify the role of microRNAs (miRNAs) as biomarkers in the progression of cervical precancerous lesions. A comprehensive search of the Cochrane Controlled Register of Trials, PubMed, ScienceDirect, and Embase databases was performed for articles published between January 2010 and June 2020. The following Medical Subject Headings (MeSH) terms were searched: “microRNA” and “cervical” and “lesion.” All study designs that aimed to evaluate the correlation of miRNA expression with different precancerous cervical staging and/or cervical cancer were included, except for case reports and case series. Approximately 82 individual miRNAs were found to be significant in differentiating the stages of cervical carcinogenesis. Among the miRNAs, miR-21 is the most prevalent, and it is consistently upregulated progressively from normal cervical to worsening cervical lesion stages in both cell and serum samples. miR-205 has been shown to have a higher specificity than human papilloma virus testing in predicting the absence of high-grade squamous intraepithelial lesions (HSILs) in exfoliated cell samples. The tumor suppressor miRNAs miR-34, let-7, miR-203 miR-29, and miR-375 were significantly downregulated in low-grade squamous intraepithelial lesions, HSILs, and cervical cancer. We found significant dysregulated miRNAs in cervical carcinogenesis with their dynamic expression changes and ability to detect viral persistency, risk prediction of low-grade lesions (cervical intraepithelial neoplasia [CIN] 2) to high-grade lesions (CIN 3), and progression of CIN 3 to cancer. Their ability to discriminate HSILs from non-dysplastic lesions has potential implications in early diagnosis and reducing overtreatment of otherwise regressive early preinvasive lesions.

Prevalence of teenage pregnancy in 2015–2016 and its obstetric outcomes compared to nonteenage pregnancy at Hospital Tuanku Ja’afar Seremban (HTJS), Negeri Sembilan, Malaysia: A retrospective case-control study based on the national obstetric registry

@#Objective: To determine the prevalence of teenage pregnancy and compare its obstetric and perinatal outcomes with those of non-teenage pregnancy. Method: This retrospective hospital-based case-control study was conducted in the Department of Obstetrics and Gynaecology in Hospital Tuanku Ja’afar Seremban. The study made use of the Malaysian National Obstetric Registry (NOR) records of teenage pregnant women aged 11–19 at Hospital Tuanku Ja’afar Seremban over a 12-month period between May 2015 and May 2016 (n=164). Socio-demographic profiles, obstetric outcomes, and perinatal outcomes were detailed for each pregnant woman. The results were compared to a control group of 169 pregnant women aged 20–30 who also delivered in hospital Tuanku Ja’afar Seremban during the same period. The aim of this study was to assess the obstetric outcomes of teenage pregnancy and to compare them with those of the control group. A chi-squared test was used to identify the statistical significance of the relationship between teenage pregnancy rates and obstetric outcomes. Results with p <0.05 was considered statistically significant. Results: The prevalence of teenage pregnancy was 2.8%. The mean age of the teenage group was 17.9; that of the control group was 26.4. Teenage mothers had a significantly higher risk of anemia (p<0.05), episiotomy (p<0.001), preterm labor (p<0.001), and delivering low-birthweight babies (p<0.001). There were no significant differences between the two groups in mode of delivery, antenatal complications, birth outcomes, APGAR scores at 5th minute, or neonatal complications. Conclusion: The prevalence of teenage pregnancy in this study is relatively low but is associated with an increased risk of some perinatal complications. The primary care physician’s role is pivotal in educating adolescents on sexual health, providing continual care in hospitals, and empowering teenagers in their reproductive health decisions.

Online formative assessments: exploring their educational value

Introduction: online formative assessments [OFA's] have been increasingly recognised in medical education as resources that promote self-directed learning. Formative assessments are used to support the self-directed learning of students. Online formative assessments have been identified to be less time consuming with automated feedback. This pilot study aimed to determine whether participation and performance in online formative assessments [OFA's] had measurable effects on learning and evaluate the students' experience of using the OFA's in the department of Obstetrics and Gynaecology

Methods: this is a cross-sectional study conducted among fourth year medical students [n=92] during their seven week postings in Obstetrics and Gynaecology. Five sets of online formative assessments in the format of one best answers [OBA], Objective structured practical examination [OSPE] and Short answer question [SAQ] with feedback were delivered over five weeks through the online portal. The mean scores of the end of posting summative exam [EOP] of those who participated in the assessments [OFA users] and of those who did not [non-OFA users] were compared, using Students t-test. The frequency of tool usage was analysed and satisfaction surveys were utilized at the end of the course by survey questionnaire using the five point Likert scale

Results: the mean scores of the students in end of posting summative examination marks for students who had participated in the online formative assessment [OFA users] and for those who had not [non OFA users] showed no significant difference in all the three components OBA, SAQ and OSPE [p=0.902, 0.633, 0.248]. Majority of the students perceived that OFAs fulfilled the stated aims and objectives and so they would persuade their peers to participate in the OFAs

Conclusions: online formative assessments are perceived as tools that promote self-directed learning, improved knowledge and tailor learning for individual learning needs and style

Neuroendocrine carcinoma of the cervix: Review of classification and current developments in diagnosis and management

Neuroendocrine carcinoma of the female reproductive tract are a heterogeneous group of rare neoplasms posing both diagnostic and therapeutic challenges. The recent classification by WHO includes neuroendocrine carcinomas (NECs) and neuroendocrine tumours (NETs). NECs are the poorly differentiated small cell carcinoma (SCNEC) and large cell neuroendocrine carcinoma (LCNEC), while well-differentiated NETs include typical carcinoids (TC) and atypical carcinoids (AC). Majority of these tumours have an aggressive clinical course and published data is supportive of multi-modal therapeutic strategies. Etoposide/platinum based chemotherapy is commonly advocated. Histopathological categorisation and diagnosis are paramount to guide therapy. Well-differentiated carcinoid and atypical carcinoid tumours should be managed similar to gastroenteropancreatic neuroendocrine tumours. This review discusses the current classification, clinicpathologic characteristics and advances in the diagnostic evaluation and the treatment options of neuroendocrine carcinoma of the cervix.

Decision making in hyperglycaemia seen in pregnancy

Delay in childbearing, family history of type 2 diabetes mellitus and obesity in childbearing years increases a possibility of glucose intolerance or overt diabetes in pregnancy which may remain unrecognised unless an oral glucose tolerance test is done. The International Association of Diabetes and Pregnancy Study Group (IADPSG, 2010) recommended the detection and diagnosis of hyperglycaemic disorders in pregnancy at two stages of pregnancy, the first stage looking for ‘overt diabetes’ in early pregnancy based on risk factors like age, past history of gestational diabetes and obesity and the second stage where ‘gestational diabetes’ at 24-28 weeks with 75 g oral glucose tolerance test. Although the one step approach with 75 g of glucose offers operational convenience in diagnosing gestational diabetes, there are concerns raised by the National Institute of Health in the recent consensus statement, supporting the two step approach (50-g, 1-hour loading test screening 100-g, 3-hour oral glucose tolerance test) as the recommended approach for detecting gestational diabetes. Medical nutrition therapy (MNT) with well-designed meal plan and appropriate exercise achieves normoglycemia without inducing ketonemia and weight loss in most pregnant women with glucose intolerance. Rapidly acting insulin analogues, such as insulin lispro and aspart are safe in pregnancy and improve postprandial glycemic control in women with pre-gestational diabetes. The long acting analogues (Insulin detemir and glargine) though proven to be safe in pregnancy, do not confer added advantage if normoglycemia is achieved with intermediate insulin (NPH). Current evidence indicates the safe use of glyburide and metformin in the management of Type 2 diabetes and gestational diabetes as other options. However, it is prudent to communicate to the women that there is no data available on the long-term health of the offspring and the safety of these oral hypoglycemic drugs are limited to the prenatal period
