Primary ovarian pregnancy

Primary ovarian pregnancy is a rare type of ectopic pregnancy, which is difficult to diagnose clinically and even intra operatively. Here we present a case of a 20-year-old woman with ruptured right ovarian pregnancy and dermoid cyst of left ovary.     

Genetic determinants of arterial calcification associated with atherosclerosis

Increasing research interest has focused on arterial calcification in the setting of atherosclerosis. Many features of atherosclerosis-related calcification provide useful clinical information. For example, calcium mineral deposits frequently form in atherosclerotic plaque, and intimal arterial calcification can be used as a surrogate marker for atherosclerosis; also, calcium deposits are readily and noninvasively quantified, which is useful because greater amounts of coronary calcification predict a higher risk of myocardial infarction and death. Several mechanisms leading to calcification associated with atherosclerosis have been proposed; however, no direct testing of proposed mechanisms has yet been reported. Studies in genetically altered animals and in humans have shed light on potential genetic determinants, which in turn could form the basis for a more comprehensive understanding of the factors affecting calcification within plaque and the associated pathobiologic implications. We review proposed molecular and cellular mechanisms of atherosclerosis-associated arterial calcification, summarize genetic influences, and suggest areas in which further investigation is needed. Understanding the molecular and genetic determinants of specific structural plaque components such as calcification can provide a solid foundation for the development of novel therapeutic approaches to favorably alter plaque structure and minimize vulnerability to arterial rupture.     

Women's perceptions of and experiences with medical student involvement in outpatient obstetric and gynecologic care in the United Arab Emirates

OBJECTIVE: The purpose of this study was to determine the experiences, satisfaction, and comfort of women with medical student participation in outpatient care during obstetric and gynecology clerkships. STUDY DESIGN: A consecutive sample of 303 women who attended the clinic were interviewed before consultation; a structured questionnaire was used. RESULTS: Two hundred sixty-four women (87.1%) accepted student involvement; 158 women (59.8%) and 173 women (66.5%), respectively, preferred female students or preceptors. Comfort levels were significantly lower with male students or preceptors in all skills that were tested (P <.0001), particularly pelvic examination and the discussion of sexual problems. Acceptance was associated significantly with older age (P <.0001), higher parity (P <.0001), higher education (P =.002), husband's occupation (P =.006), obstetric consultation (P <.0001), previous teaching encounters (P =.0006), recognition of the students' roles (P =.004), and satisfaction with clinical service (P = 0.01). Reasons for nonacceptance (n = 39 women, 12.9%) were concern about privacy during examination (53.8%) or counseling (25.6%) and the extent of the students' involvement (20.5%). CONCLUSION: Most women agreed to participate in the teaching of obstetric and gynecologic skills to medical students.     

Role of self-efficacy and behaviour change

Behaviour change is an important concept in relation to health promotion and disease prevention. Self-efficacy has been identified as an important determinant of health behaviour, future health behaviour and health behaviour change. In order to effectively facilitate behaviour change, it is essential that interventions are research based, and emphasize the utility of theory in practice. The effective practice of health promotion and disease prevention requires a full understanding of the processes of patient behaviour. This article presents the role of the nurse in influencing health-related behaviour change. Self-efficacy and related but distinct theories that underpin behaviour change are discussed. The empirical evidence that supports the link between self-efficacy and predictions of health behaviours is also examined.     

Fibroscan of chronic HCV patients coinfected with schistosomiasis

Background and study aimsBoth hepatitis C virus (HCV) and schistosomiasis are highly endemic in Egypt and coinfection is frequently encountered. Such coinfection is responsible for leading to a more severe liver disease. Hence, the aim of the study was to assess the fibroscan in chronic HCV patients coinfected with Schistosoma.Patients and methodsThis study included 231 chronic HCV patients. Routine pre-treatment work-up was done including anti-schistosomal antibodies. Liver stiffness measurements using fibroscan and reference needle-liver biopsy were done. Patients were categorised into two groups: HCV patients with positive schistosomal serology and HCV patients with negative schistosomal serology.ResultsAnti-schistosomal antibody was positive in 29% of the studied population. Positive schistosomal serology status was significantly associated with the disagreement between the results of liver biopsy (Metavir) and the fibroscan results (p value = 0.02), which was more obvious in F2 and F3 fibrosis stages. The sensitivity of fibroscan for the detection of the F2 stage decreased from 64% among negative schistosomal serology patients to 30.8% among positive schistosomal serology patients, and for the F3 stage it decreased from 43.8% to 21.4%, respectively. Multivariate logistic regression showed that fibrosis stages (F0–F1 and F4) were the most independent factors that were associated with the agreement between fibroscan and liver biopsy (odds ratio (OR) 3.4, 7.12 and p value <0.001, <0.001, respectively).ConclusionAlthough the sensitivity of fibroscan for the detection of fibrosis stages (F2 and F3) was impaired in patients with positive schistosomal serology, fibrosis stages (F0–F1 and F4) were the most independent factors associated with the agreement between fibroscan and liver biopsy.     

Imported tropical diseases

Imported tropical diseases are among the top three leading causes for morbidity and may affect up to 8% of returning travelers. Because the spectrum of dermatological manifestations seen in travelers is broad, it can be challenging for physicians to recognize and treat such conditions in a timely and efficient manner. Therefore, the present review highlights common imported tropical diseases with a focus on treatment regimens. Specifically, cutaneous larva migrans, myiasis, swimmer's itch, mycetoma, Chagas disease, and leishmaniasis are discussed. As awareness increases among travelers, immigrants, and health care providers regarding imported tropical diseases, early intervention and proper diagnosis can ensue, thus reducing morbidity and mortality in affected individuals.
