Ambulatory Hysteroscopy Results Post-Menopause: Comparative Study Between Patients With and Without Metrorrhagia

Our objective was to compare the results of ambulatory hysteroscopy in postmenopausal women with and without uterine bleeding. A retrospective descriptive study was carried out on 236 women who were at least 2 years into the menopause, who were not undergoing hormone treatment and who had had abnormal pelvic ultrasound results. Of these women, 150 were asymptomatic and 86 reported haemorrhage. Diagnostic and operative outpatient hysteroscopy was performed between January 2002 and December 2003. There was no difference between the two groups regarding age of patients, age of menopause and presence of at least one of the risk factors for endometrial carcinoma evaluated, although obesity was more frequent in the symptomatic group. Abnormal ultrasound results for these women corresponded in the majority of cases to intracavitary disease, and the absence of organic endometrial pathology was 9.3% vs 11.3% in each group. The more frequent pathology was benign endometrial polyps (64% in bleeding patients and 84.7% in asymptomatic ones). Endometrial carcinoma was diagnosed in 23.3% of women with metrorrhagia and in 1.3% of asymptomatic women. We diagnosed 2.6% of malignancy inside polyps. Hysteroscopy results were confirmed by histology in 90.3% of cases. See and treat in one session was achieved in 91% of benign endometrial polyps. Ambulatory hysteroscopy has high sensitivity and specificity for intracavitary pathology and high tolerability and safety. See and treat in one session can be achieved in the majority of lesions with indication for excision. These results make us advise our menopausal patients with abnormal uterine bleeding to undergo diagnostic hysteroscopy complemented with biopsy.

Office Hysteroscopy After Ultrasonographic Diagnosis of Thickened Endometrium in Postmenopausal Patients

The aim of our study was to access office hysteroscopy results in postmenopausal patients with thickened endometrium. A retrospective descriptive study was carried out on 245 postmenopausal patients submitted to office hysteroscopy after sonographic diagnosis of thickened endometriumin 20 consecutive months.Women were evaluated for age, hormonal therapy, hysteroscopic findings, procedure duration, complications and associated pain, and histological diagnosis. Patients with and without uterine bleeding were considered separately. Symptomatic patients were older and had longer procedure duration. The most frequent hysteroscopic finding was endometrial polyp in both groups. Pain was subjectively assessed in a numeric scale from 0 to 10 and median value was 4. There were no complications reported. Global neoplasia rate was 2.9% for asymptomatic patients and 16.4% for symptomatic ones (p<0.05). Thickened endometrium with postmenopausal metrorrhagia gave patients a significantly higher risk for neoplasia and hyperplasia.

Gravidez Após Polipectomia por Ressectoscopia

As anomalias da cavidade uterina e, nomeadamente os pólipos endometriais, são uma importante causa de subfertilidade. Com o objectivo de determinar um impacto do pólipo endometrial na ocorrência de a gravidez, avaliaram-se retrospectivamente 74 mulheres, da consulta de infertilidade da maternidade Dr. Alfredo da Costa, com aquele diagnóstico e que foram ou não sujeitas a cirurgia correctiva, entre Janeiro de 1997 e Dezembro de 2000. 20 das mulheres apresentavam factores adicionais de infertilidade das quais 14 foram submetidas a técnicas de procriação medicamente assistida (PMA). Considerando as mulheres sem factores adicionais de infertilidade e com factores de infertilidade submetidas a PMA, ocorreram 10 gravidezes entre as 31 mulheres que realizaram polipectomia e 6 entre as 33 que não efectuaram esta cirurgia correctiva, não tendo sida esta diferença estatisticamente significativa. Ocorreram 3 abortos nas mulheres não sujeitas a polipectomia. Não foram detectadas diferenças entre os pólipos com mais ou menos 2cm. Neste estudo parece existir uma relação positiva entre a polipectomia e a ocorrência de gravidez, no entanto para melhor avaliação sugere-se o prolongamento do período e a determinação objectiva do número de gravidezes e o seu desfecho.

The Shading Sign: Is It Exclusive of Endometriomas?

OBJECTIVES: To investigate if the shading sign is an exclusive MRI feature of endometriomas or endometrioid tumors, and to analyze its different patterns. METHODS: Three hundred and fourty six women with adnexal masses who underwent 1.5/3-T MRI were included in this retrospective, board-approved study. The shading sign was found in 56 patients, but five cases were excluded due to lack of imaging follow-up or histological correlation. The final sample included 51 women. The type of tumor and the pattern of shading were recorded for each case. RESULTS: Thirty endometriomas and five endometrioid carcinomas were found. The remaining 16 cases corresponded to other benign and malignant tumors. The overall sensitivity, specificity, positive predictive value, and negative predictive value were 73%, 93%, 59%, and 96%, respectively. Restricting the analysis to cystic lesions without solid or fat component, sensitivity, specificity, positive predictive value, and negative predictive value were 73%, 96%, 94%, and 80%. Five shading patterns were identified: layering (15.7%), liquid-liquid level (11.8%), homogenous (45.1%), heterogeneous (11.8%), and focal/multifocal shading within a complex mass (19.6%). No significant correlation was found between these patterns and the type of tumor. CONCLUSIONS: The shading sign is not exclusive of endometriomas or endometrioid tumors. Homogenous shading was the most prevalent pattern in endometriomas and half of the cases with focal/multifocal shading within a complex mass were endometrioid carcinomas.

Importância da Prova de Synacthen no Diagnóstico Diferencial de Pubarca Precoce

Introdução: Nos doentes com pubarca precoce, o gold-standard para o diagnóstico diferencial entre pubarca precoce idiopática (PPI) e a forma não clássica da hiperplasia congénita da suprarrenal (HCSR--NC) é a prova de Synacthen. Esta permite também estimar a reserva adrenal de cortisol nos doentes com HCSR-NC.Objetivos: Comparar as características clínicas e perfil hormonal basal dos doentes com pubarca pre-coce; avaliar a importância da prova de Synacthen no diagnóstico diferencial entre PPI e HCSR-NC e na determinação da reserva adrenal de cortisol. Material e métodos: Estudo transversal de doentes com pubarca precoce que realizaram prova de Synacthen. Resultados: Foram incluídos 43 doentes, com idade mediana de 7,5 anos (3,5-9,4), sendo 37 (86,0%) do sexo feminino. Na prova de Synacthen, 37 (86,0%) foram classificados como PPI e 6 (14,0%) como HCSR-NC.Não houve diferencças significativas entre os 2 grupos quanto às características clínicas e doseamentos basais de ACTH, cortisol e androgénios da suprarrenal. A 17-OHP basal e estimulada foi mais elevada nos doentes com HCSR-NC (p = 0,001 e p < 0,001, respetivamente) (basal: 4,62 ± 3,70 ng/ml [0,80-10,50];estimulada: 35,41 ± 24,87 ng/ml [12,0-80,2]) do que nos doentes com PPI (basal: 1,04 ± 0,77 ng/ml [0,22-3,80]; estimulada: 4,18 ± 1,71 ng/ml [1,0-8,96]). O cut-off basal habitualmente proposto (< 2,0 ng/ml) paraa distinção entre estes grupos não o permitiu em 2 doentes, que apenas foram diagnosticados após realização da prova de Synacthen. Dois doentes com HCSR-NC (33,3%) tiveram cortisol após estimulação< 18 g/dl, revelando necessidade de tratamento com glucocorticoide em stress. Os doentes com HCSR--NC com valores mais elevados de 17-OHP basal tiveram valores de cortisol mais baixos após estimulação(p = 0,004; r = -0,43).Conclusão: A realização desta prova foi útil para distinguir os doentes com HCSR-NC e PPI, pois nenhum valor de 17-OHP basal permitia fazer o diagnóstico diferencial definitivo. Em alguns doentes com HCSR-NCa prova revelou secreção inapropriada de cortisol em stress, contribuindo para a decisão terapêutica.
