Hydatidiform Mole in Ectopic Pregnancy Clinical, Imaging, Pathological and Immunohistochemical Characteristics

OBJECTIVE: To determine the clinical, pathological, immunohistochemical and imaging characteristics of hydatidiform mole in ectopic pregnancy (HMEP) in all the cases admitted to the Department of Obstetrics and Gynecology, University Hospital of Caracas (HUC), Central University of Venezuela.STUDY DESIGN: Retrospective and comparative study, based on clinical records review of 2 groups: 10 cases with a diagnosis of HMEP and 20 cases with intrauterine hydatidiform mole (IUHM) admitted to the Obstetrics and Gynecology Department of HUC from 1996 to 2010. Clinical, pathological, immunohistochemical and imaging features were analyzed.RESULTS: The prevalence of HMEP in this study was 0.14:1,000 pregnancies; in this group the mean age was 28.8 years, and the mean gestational age at admission was 8.6 weeks. Both groups (HMEP and IUHM) were comparable in these last variables. Abdominal pain and genital bleeding were the most common clinical symptoms in the HMEP group, while it was vaginal bleeding in the IUHM group. Ultrasound findings were similar to those traditionally described in nonmolar ectopic pregnancy. Histology and immunohistochemistry showed that all cases of HMEP were partial mole.CONCLUSION: Although in this study the prevalence of HMEP was high, the size of the sample limits definitive conclusions. This study concludes that all cases of HMEP are partial mole. (J Reprod Med 2012;57:329-332)

Evaluation of hardness and colour change of soft liners after accelerated ageing.

INTRODUCTION: Soft liners have been developed to offer comfort to denture wearers. However, this comfort is compromised when there is a change in the properties of the material, causing colour change, solubility, absorption and hardening. These characteristics can compromise the longevity of soft liners. AIM: The aim of this in vitro study was to investigate the effect of ageing on both the hardness and colour change of two soft liners following accelerated ageing. METHODS: Two denture liners, one resin based (Trusoft, Bosworth, Illinois, USA) and one silicone based (Ufi Gel P, Voco GMBH, Cuxhaven, Germany), were tested in this study for both hardness (using the Shore A scale) and colour change (using the CIE L*a*b* colour scale), initially and after 1008 hours (6 weeks) of accelerated ageing. Statistical analysis was performed using the unpaired t-test with the Welch correction. RESULTS: These indicated that both materials increased in hardness and underwent colour change after accelerated ageing. The initial hardness of Trusoft was far lower than that of Ufi Gel P (18.2 Shore A units vs 34.8 Shore A units). However, for Trusoft the changes for both hardness (from 18.2 to 52.1 Shore A units) and colour change (16.85 on the CIE L*a*b* colour scale) were greater than those for Ufi Gel P, for which hardness changed from 34.8 to 36.5 Shore A units and the colour change was 5.19 on the CIE L*a*b* colour scale. CONCLUSIONS: Ufi Gel P underwent less hardness and colour change after accelerated ageing than Trusoft. On the other hand, the use of Trusoft may be preferable in cases where initial softness is a major consideration, such as when relining an immediate denture after implant surgery.

Design and validity of a questionnaire to assess sexuality in pregnant women

Background. A review of validated methods for assessing female sexual dysfunction and a review of male and female sexual dysfunction did not refer to any specific questionnaire for evaluating sexuality during pregnancy. A study was performed at the Obstetrics and Gynecology Department of Botucatu Medical School, São Paulo State University, Brazil to design and validate a pregnancy sexuality questionnaire, the Pregnancy Sexual Response Inventory (PSRI). Methods. Women with a singleton pregnancy between 10 and 35 weeks of gestation were randomly recruited. There were five phases in the development of the PSRI: (1) item selection; (2) item development; (3) determination of internal consistency, reliability and convergence; (4) content validity; and (5) determination of inter-interviewer reliability. Internal consistency and reliability were evaluated using Cronbach's alpha. Inter-interviewer reliability was assessed by evaluating the responses of 18 academics at various institutions, using Kappa Index and Student t test. Results. Good internal consistency and reliability were obtained (Cronbach's alpha coefficient = 0.79). Among the 18 academics, 13 totally agreed (K = 1.0), three partially agreed (K = 0.67) and two disagreed (K = 0.33) with the proposed questions. Comparisons of the mean PSRI domain scores made between the primary investigators and the other interviewers showed no significant differences in all domains (p > 0.05). Conclusion. PSRI is a new validated instrument for evaluating sexuality and sexual activity and related health concerns during pregnancy. © 2009 Rudge et al; licensee BioMed Central Ltd.
