Postmenopausal Bleeding and Endometrial Changes: Clinical Significance?

Introduction: Postmenopausal bleeding is a common complaint from women seen in general practice, although majority of them, will have no major problem. Objective: Study of endometrium in postmenopausal women with suspicious sonographic endometrial changes. Comparison of findings in asymptomatic women and those who reported metrorrhagia. Methods: Consultation of outpatient medical records of 487 women undergoing endometrial study (sonohysterography, hysteroscopy), between January/2004 and July/2010. Patients were subdivided into two groups: women with (G1) and without (G2) complaints of postmenopausal metrorrhagia. Results: G1 and G2 comprises 78 and 409 women, respectively. G1: 23.1% normal uterine cavity, 74.3% benign pathology (majority endometrial polyps) and 2.6% of them endometrial carcinoma. G2: 14.4% normal uterine cavity, 83.7% benign pathology (majority endometrial polyps), 1.4% endometrial hyperplasia and endometrial carcinoma in 0.49%. Conclusion: Postmenopausal metrorrhagia is associated with an increased risk of endometrial malignancy, in relation to asymptomatic, although represents a minority of the population. To highlight the existence of premalignant and malignant pathology in asymptomatic endometrial thickening.

Tamoxifeno e Espessamento Endometrial Assintomático

Tamoxifen is a first-line agent for adjuvant treatment of estrogen-receptor positive breast cancer, and is used to reduce the risk of this condition in high-risk individuals. Retrospective studies established an association between tamoxifen use, endometrial thickness and endometrial cancer. There have been many attempts to identify an effective screening program for tamoxifen-related endometrial cancer, which have led to the use of transvaginal ultrasound and invasive procedures. The use of a 5mm endometrial cut-off in vaginal ultrasound is known to raise the number of endometrial biopsies with no gain in early cancer diagnosis. A review of the scientific literature was performed in order to establish the best available evidence for endometrial evaluation of asymptomatic breast cancer patients on tamoxifen.

Case Report of Malignant Endometrial Polyps

The aims of this retrospective review were to determine the frequency of malignant endometrial polyps diagnosed with ambulatory hysteroscopy in the Obstetrics/Gynaecology Department of HDE, Lisbon, between January 2001 and December 2005 and to characterize these cases according to risk factors, sonographic and endoscopic findings tumoral histology, and tumor stage.We found seven cases of malignant endometrial polyps in a total of 1333 polyps initially diagnosed: an incidence rate of 0. 53%. These seven patients had a mean age of 68 years (55–82 years), and all were postmenopausal, with five having one risk factor each for endometrial cancer. Metrorrhagia was present in six of the seven patients(85.7%). Ultrasonography was abnormal in all seven patients, with a mean endometrial thickness of 26 mm(range: 12–44 mm). The hysteroscopy images suggested malignancy in all cases. All except one patient had a single polyp. The polyps had volumes between 1.5 and 3 cm; two were removed completely and five were biopsed. The histological subtype was: mixed endometrioid/serous papillary or clear cell (2), adenocarcinoma with squamous differentiation (2), carcinosarcoma (2), and clear cell carcinoma (1). Malignancy inside polyps is rare, but diagnostic hysteroscopy with visual guided biopsies can identify these cases in the earlier stages. The risk factors are not different from those of other endometrial carcinomas, but the histological subtype seems to point to more aggressive cancers.

Orbital Exenteration for Eyelid Skin Carcinoma

Exenteration of the orbit is a disfiguring and destructive procedure; it is generally performed for orbital malignancies and often provides a significant reconstructive challenge. Our purpose was to evaluate the clinical indications for orbital exenteration in a tertiary referral center and to assess the reconstructive options employed. A retrospective nonrandomized analysis was performed, selecting all patients undergoing orbital exenteration over a 5-year period, between January 2005 and January 2010. Patient demographics, tumor characteristics, and reconstructive techniques used were evaluated. Twenty patients with a mean age of 76.5 years underwent total orbital exenteration. Basal cell carcinoma was the main operative indication (45%), followed by squamous cell carcinoma (15%). Reconstructive techniques included cover of the raw orbital cavity with a temporal muscular flap in all cases followed with split skin grafting (25%), bilaterally pedicle V-Y advancement flap (10%) and a fasciocutaneous island flap of the retroauricular region (65%). Twenty percent of patients had local complications and all were treated in a satisfactory fashion. Eyelid skin tumors remain an important cause of orbital exenteration. Temporal muscle flap is a reliable and stable reconstructive solution after orbital exenteration and additional aid is supplied with skin grafts or local flaps. This technique ensures a good aesthetic outcome and better situation for later complementary treatments and minimal associated donor site morbidity.

Tuberculose Genital. Uma Causa Rara de Hemorragia Pós-Menopausa

Introdução: A tuberculose continua um problema de saúde pública emergente. A incidência da tuberculose genito-urinária tem vindo a aumentar sendo o segundo local mais comum de infecção a seguir aos pulmões. Caso clínico: Os autores apresentam dois casos de mulheres com hemorragia vaginal pós-menopausa. O exame clínico não revelou alterações. A ecografia pélvica endocavitária detectou a presença de uma lâmina líquida na cavidade endometrial em ambos os casos. A histeroscopia identificou espessamentos focais do endométrio que foram biopsados. O exame anatomopatológico revelou granulomas de células epitelióides sem atipia celular. O exame cultural do endométrio foi positivo para Mycobacterium tuberculosis. Não foi detectado envolvimento de outros órgãos tendo as doentes iniciado terapêutica antibacilar. Conclusão: A tuberculose genital é rara na mulher pós-menopausa sendo responsável por cerca de 1% da hemorragia vaginal pós-menopausa. No entanto, é uma doença curável cujo diagnóstico precoce é importante, prevenindo a utilização de procedimentos invasivos desnecessários.

Summer Vacations not Only a Memory for Life, but Also a Rare Infection

Introduction: Rhinoscleroma is a rare, chronic, granulomatous disease that most frequently affects the upper respiratory tract, especially the nasal cavity and sometimes extends through the lower respiratory tract. Is associated with Klebsiella rhinoscleromatis, which is endemic in certain geographic regions namely Central America. The pathogenesis and risk factors remain unclear. Clinical case: We report a five years Old Portuguese boy, previously healthy, brought to the Emergency Department with epistaxis, without other accompanying signs or symptoms. The Otorhinolaryngologist (ORL) performed rhinoscopy and identified an intranasal bleeding mass. The MRI revealed an intranasal mass with extension to the ethmoid bone sinus, and performed biopsy. The histopathology was vital, making the diagnosis of Rhinoscleroma. The child had traveled abroad for the first time on vacations a year before to Dominican Republic. The bacteriologic exam identified a Klebsiella spp. sensible to the association of amoxicillin and clavulanic acid. Blood test performed excluded association of immunodeficiency. Since it’s a rare disease genetic study are under course. Monthly evaluation by ORL and pediatrician was performed which documented progressive reduction until total disappearing of the macro and microscopic lesion, and negative bacteriologic exam. Six months of antibiotic therapy were completed without any known secondary effects. The child remained asymptomatic up to the last visit, 3 months following treatment and has shown no evidence of recurrence. Conclusion: Globalization and free transit of people to areas far from origin countries here some rare diseases are endemic brings a new challenge to modern medicine. Sometimes vacations bring more than memories.

McCune Albright Syndrome: A Diagnosis to be Kept in Mind

Precocious puberty, defined as the development of secondary sexual characteristics before the age of 8, often leads to anxiety in patients and their families but also in clinicians searching for the final diagnosis. After adequate investigation, the majority of the cases in girls turn out to be idiopathic. The authors present a case of McCune Albright syndrome in order to call attention to a rare cause of sexual precocity and the value of ultrasound in the evaluation of these situations. 10 years old infant girl admitted in our department due to irregular menstrual bleeding. She experienced a vaginal bleeding by the age of 3 which led to the diagnosis of McCune Albright Syndrome after a complete evaluation. Pubertal assessment revealed a reversed sequence in the remaining events with adrenarche at 5 and thelarche at 8. Hormonal evaluation demonstrated low FSH and LH levels (11,2 and 6,72 respectively) with high estrogen (204). Pelvic ultrasound showed a normal sized uterus (73x 29x32 mm), endometrial thickness of 5 mm and ovaries with several microfollicles and a copus luteum measuring 23 mm in the right ovary. McCune Albright syndrome is a very uncommon cause of sexual precocity that should, however, be suspected in all infant girls who present with vaginal bleeding. It is characterized by a triad: polyostotic fibrous dysplasia, gonadotropin-independent precocious puberty and café-au-lait skin spots. Due to autonomous production of estrogen by the ovaries, ultrasound image of the female reproductive tract is inconsistent with chronologic age. Pelvic ultrasound demonstrates a normal sized uterus with a well defined cervix and clearly identified ovaries with several follicles, similar to adult women of reproductive age. Ultrasonography of the pelvis has also an important role excluding other causes of GnRH-independent precocious puberty conditions like ovarian cysts or tumors.

Estudo do Aborto Recorrente. Ainda há Lugar para a Histerossalpingografia?

Overview and Aims: The investigation of recurrent miscarriage includes the study of uterine morphology. 3D ultrasound allows the evaluation of the morphology (cavity and outer contour), reducing the need for invasive tests such as hystero - salpingography (HSG), hysteroscopy and laparoscopy. We evaluated the diagnostic agreement between HSG and 3D ultrasound in the study of the uterine cavity morphology. Study Design: Prospective study. Population: A total of 34 women referred to our institution with a history of recurrent miscarriage. Methods: To compare the results of 3D ultrasound and HSG, all women underwent both exams. 3D scans were performed by the same operator and HSG were evaluated by the same clinician. The concordance study was performed using the Kappa coefficient. Results: With 3D ultrasound and HSG, uterine anomalies were diagnosed in 52.9% (18/34) and 47% (16/34) of the cases and congenital malformations were the most frequent findings. The agreement between the two techniques was excellent(K = 0.825). The three cases of diagnostic disagreement were analyzed. Conclusion: A high level of diagnostic agreement was observed between HSG and 3D ultrasound. The 3D ultrasound, a low cost and well tolerated technique, when performed by an experienced operator, is the first line exam to study the uterine morphology in women with recurrent miscarriage.

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.
