The impact of positive peritoneal washings and serosal and adnexal involvement on survival in patients with stage IIIA uterine cancer

Objective. The aim of this study was to determine the prognostic significance of serosal involvement (SER), adnexal involvement (ADN), and positive peritoneal washings (PPW) in patients with Stage IIIA uterine cancer. We also sought to determine patterns of recurrence in patients with this disease. Methods. The records of 136 patients with Stage IIIA uterine cancer treated at the Queensland Centre for Gynecological Cancer between March 1983 and August 2001 were reviewed. One hundred thirty-six patients underwent surgery and 58 (42.6%) had full surgical staging. Seventy-five patients (55.2%) had external beam radiotherapy and/or brachytherapy postoperatively. Overall survival was the primary statistical endpoint. Statistical analysis included univariate and multivariate Cox models. Results. Forty-six patients (33.8%) had adnexal involvement, 23 (16.9%) had serosal involvement, and 40 (29.4%) had positive peritoneal washings. Median follow-up was 55.1 months (95% confidence interval, 36.9 to 73.4 months) after which time 71 patients (52.2%) remained alive. For patients with endometrioid adenocarcinoma, ADN and SER were associated with impaired survival on multivariate analysis (odds ratio 2.8 and 3.2, respectively). In the subgroup of patients with high-risk tumors (including papillary serous carcinomas, clear cell carcinomas, and uterine sarcomas), neither ADN, nor SER, nor PPW influenced survival. Conclusion. Patients with Stage IIIA uterine cancer constitute a heterogeneous group. For patients with endometrioid adenocarcinoma, both ADN and SER, but not PPW, were associated with impaired prognosis. For patients with high-risk histological types, prognosis is poor for all three factors. (C) 2002 Elsevier Science (USA).

Urinary incontinence across the lifespan

Aims: The objectives of the current study were (1) to measure type and severity of urinary leakage and (2) to investigate the association between these factors and age-related life events and conditions in three groups of Australian women with a history of urinary leakage. Methods: Five hundred participants were randomly selected from women in the young (aged 18-22 in 1996), mid-age (4550),and older (70-75) cohorts of the Australian Longitudinal Study of Women's Health (ALSWH) who had reported leaking urine in the 1996 baseline survey. Details about leaking urine (frequency, severity, situations) and associated factors (pregnancy, childbirth, body mass index [BMI]) were sought through self-report mailed follow-up surveys in 1999. Results & Conclusions: Response rates were 50, 83, and 80% in the young, mid-age, and older women, respectively. Most women confirmed that they had, leaked urine in the past month, and the majority of these were cases of mixed incontinence. Incontinence severity tended to increase with BMI for women of all ages, and increased severity scores were associated with having urine that burns or stings. Additional independent risk factors for increasing incontinence severity were heavy smoking in young women, past or present use of hormone replacement therapy in older women, and BMI and history of hysterectomy in mid-age women.

Parathyroid hormone venous sampling prior to reoperation for primary hyperparathyroidism

Background: The surgical cure rate for primary hyperparathyroidism is greater than 95%. For those who have recurrent or persistent disease, preoperative localization improves reoperation success rates. Selective parathyroid venous sampling (SPVS) for intact parathyroid hormone is particularly useful when non-invasive localization techniques are negative or inconclusive. Methods: We present all known cases (n = 13) between 1994 and 2002 who had venous sampling for localization at our institution prior to reoperation for recurrent or persistent primary hyperparathyroidism. Comparison was made with non-invasive localization procedures. Results of invasive and non-invasive localization were correlated with surgical findings. Results: Of the nine reoperated cases, eight had positive correlations between SPVS and operative findings and histopathology. SPVS did not reveal the parathyroid hormone source in one case with negative non-invasive localization procedures. Comparisons between SPVS, computerized tomography (CT), and parathyroid scintigraphy (MIBI) as expressed in terms of true positive (TP), false positive (FP) and false negative (FN) were: SPVS - TP 88.8%, FP 0%, FN 11.1%; CT - TP 22.2%, FP 22.2%, FN 55.5%; and MIBI - TP 33.3%, FP 0%, FN 66.6%. At least seven of the nine operated cases have been cured; another remained normocalcaemic 2 weeks after subtotal parathyroidectomy. Conclusion: In our institution SPVS has proven to be a valuable tool in cases with recurrent or persistent primary hyperparathyroidism and negative non-invasive localization procedures.

Pregnancy rates and predictors in women with HIV/AIDS in Rio de Janeiro, Southeastern Brazil

OBJECTIVE: To assess incidence and predictors of first pregnancy among women with HIV/AIDS. METHODS: Prospective cohort study was conducted in Rio de Janeiro, southeastern Brazil, between 1996 and 2003. This study comprised 225 women with HIV/AIDS followed up until their first pregnancy or first censored event (hysterectomy, tubal ligation, menopause, 50 years of age, loss to follow-up, death or the end of December 2003). Pregnancy and abortion rates were estimated, and Cox proportional hazards models were used to identify baseline characteristics associated with pregnancy risk. RESULTS: The women were followed up for 565 person/years with a median follow-up of 3 years per women. The mean age was 32 years (SD: 7), and 54.7% were white. There were 60 pregnancies in 39 women, and 18 were terminated (induced abortions), accounting for a rate of 6.9% and 2.1% women/year, respectively. Repeated pregnancies occurred in 33.3% of the women (13/39). Higher pregnancy risk was seen among younger women (HR=3.42; 95%CI: 1.69;6.95) and those living with their partners (HR=1.89; 95%CI: 1.00;3.57). Lower pregnancy risk was associated with higher education level (HR=0.43; 95%CI: 0.19;0.99) and use of antiretroviral therapy (HR=061; 95%CI: 0.31;1.17). CONCLUSIONS: Lower pregnancy rates were found in our cohort than in the general population. Sociodemographic characteristics should be taken into consideration in the management of reproductive health in HIV-positive childbearing age women. Reproductive and family planning counseling must be incorporated into HIV/AIDS programs for women to help preventing HIV transmission to their partners and offspring.

Aspectos Imagiológicos da Trombose Venosa Cerebral numa Mulher Grávida

A trombose venosa cerebral (TVC) é uma doença relativamente rara mas grave, potencialmente reversível com diagnóstico atempado e terapêutica médica adequada. A gravidez e o puerpério são um factor predisponente de TVC, que é responsável por 6% das causas de morte materna. As manifestações clínicas dependem da localização, extensão do trombo, bem como da rede de colaterais existente. Apresentamos o caso duma doente do sexo feminino, 33 anos, grávida de 13 semanas que recorreu ao serviço de urgência por quadro de cefaleias e cujo estudo por Ressonância Magnética revelou aspectos compatíveis com doença venosa oclusiva subtotal do seio longitudinal superior em fase aguda. A propósito deste caso discutimos as manifestações imagiológicas da trombose venosa dural na fase aguda.

Necrose Intestinal na Criança

O termo necrose intestinal traduz exclusivamente um conceito anatomopatológico e clínco, e implica sempre um isquémia instestinal oclusiva ou não. A enterocolite necrosante, em sentido lato, implica uma isquémia intestinal não oclusiva associada a um mecanismo infeccioso. O factor desencadeante da necrose é, por vezes, difícil de determinar. A enterocolite necrosante ocorre em 90% dos casos em recém-nascidos prematuros, sendo mesmo frequente no recém-nascido de termo e rara na crança mais velha e no adulto. Apresentam-se os casos clínicos de duas crianças; uma de sete anos com antecedentes de neutropénia crónica e outra de onze anos com défice cognitivo grave, dismorfia e alterações de comportamento, ambas internadas por quadro de abdómen agudo e choque. Foi efectuada ressecção do segmento jejunal num dos casos e ressecção subtotal do cólon no outro, por necrose. Apesar da cirurgia e da terapêutica médica de suporte, ambas acabaram por morrer em falência multiorgânica, respectivamente três horas após a cirurgia e ao 14º dia de internamento, após segunda intervenção com ressecção do segmento necrosado íleon. A necrópsia de ambos os casos revelou necrose extensa de todo o restante intestino. Os dois casos clínicos comportaram-se como enterocolite necrosante da criança, sendo o diagnóstico de exclusão numa delas, de enterocolite neutropénica. Efectua-se uma revisão dos mecanismos etiopatogénicos da necrose intestinal da criança, desde os tromboembólicos, obstrutivos extrínsecos ou endoluminais, inflamatórios, isquémicos não oclusivos, até aos infecciosos. Para além das medidas gerais de terapêutica, salienta-se a necessidade de uma intervenção cirúrgica precose e de meios diagnósticos terapêuticos, como o doseamento, no sangue e na urina, da proteína de ligação aos ácidos gordos intestinais e a arteriografia selectiva.

Implante Contraceptivo Não Palpável - Estratégias para a sua Localização e Remoção

Overview and Aims: The contraceptive implant is frequently used to provide contraceptive protection over three years. The implant is inserted into the subcutaneous tissue of the upper arm, and should be palpable and easily removed. We evaluated the best imaging strategy for non-palpable implant (Implanon®) localization and removal. Study Design: Retrospective study. Population: A total of 11 women referred to a tertiary care hospital, between October 2009 and January 2012, for localization and removal of their non-palpable implants. Methods: Different localization methods (ultrasound and magnetic resonance imaging) were evaluated for non-palpable rod. Results: Seven of the nonpalpable implants were inserted in a health care center, three in a district hospital and one in a private clinic. In three women, the reasons for requesting removal were the end of the implant validity, two wanted to become pregnant, two had weight gain, one had weight loss, one referred irregular bleeding, one had two implants and one did a hysterectomy. In 81.8% (9) of the women, the implants were identified and localized by ultrasound, and successfully removed. In two patients the implant was not found and therefore not removed. Conclusions: In our study, high resolution ultrasound proved to be a sensitive method in implants localization, being the primary choice for determining the location of nonpalpable implants.

Uma Complicação Grave da Embolização das Artérias Uterinas

Uterine artery embolisation has been used as a therapeutic alternative for symptomatic uterine myomas. It is considered a safe and effective procedure, with very few cases published involving complications. The authors present a case of a 35-year-old nulliparous woman with an intramural myoma with 161x143x85mm, submitted to an uterine artery embolisation complicated by uterine necrosis. A hysterectomy was performed. This casereport reinforces the idea that artery embolization is not a riskfree procedure and serious complications may occur. Therefore, patients should be carefully selected.

Ovarian Borderline Tumor and Fertility-Sparing Surgery

Ovarian borderline tumors (OBTs) are frequently diagnosed in women of reproductive age. There is no consensus about their management, and it sometimes represents a dilemma aboutwhat should be done: fertility sparing surgery or a hysterectomy with salpingo-oophorectomy? Case: A 32-year-old nulligravida, diagnosed with a right ovarian borderline tumor is presented. She underwent pelvic washings, right salpingo-oophorectomy, appendectomy, and omental and peritoneal biopsies (laparotomic approach). Macroscopically, the left ovary was normal and subsequent exploration for staging was also normal, including the lymph nodes. Intraoperatively, frozen section examination was unclear, suggesting an OBT. Results: The final histopathologic diagnosis was ovarian borderline tumor, stage IIC (International Federation of Gynecology and Obstetrics [FIGO] staging). The patient expressed a desire to preserve her fertility. Thirty-six months postsurgery, she became pregnant spontaneously and delivered a healthy newborn at term. Conclusions: Conservative surgery can be performed in young patients treated for an OBT, provided they are closely followed up and that this surgery is performed after careful consideration and informed consent. It is, however, controversial with respect to performing hysterectomy and salpingo-oopherectomy upon the patient’s completion of childbearing.

Miocardiopatia Periparto. Paragem Cardiorespiratória Pós-Parto Complicada por Acretismo Placentar

Peripartum cardiomiopathy is a rare and life-threatening cardiac disease that affects young women previously healthy, during the peripartum period. It is a form of dilated cardiomyopathy with left-sided systolic dysfunction, which may lead to symptoms and signs of congestive heart failure. The exclusion diagnosis is based essentially on clinical presentation and initial symptoms may mimic physiologic alterations of pregnancy. The authors present a case of a 34 week multiple gestation with a growth restriction of one of the fetus and with a suspicion of a mild pre-eclampsia, motive by which we decided labour induction. During placental expulsion, in which we noticed difficulty in finding placental cleavage, the patient presented an assistoly, recovering after cardiorespiratory reanimation. However, the profuse bleeding after labour leaded to a life saving hysterectomy. Histological examination revealed placenta accreta. The echocardiography performed post-operatively diagnosed a dilated cardiomyopathy.

Correlação manométrico-radiológica e sua importância no tratamento cirúrgico do megaesôfago chagásico

Foram analisados os achados radiológicos e manométricos de 43 pacientes portadores de megaesôfago chagásico com sorologia positiva para doença de Chagas. Encontrou-se uma redução significante dos valores da pressão máxima do corpo do esôfago com relação ao estádio da esofagopatia: grau I/II - 42,9mmHg; grau III - 23,6mmHg; grau IV - 15,6mmHg. Observou-se que cinco (35,7%) pacientes classificados como grau III, do ponto de vista radiológico, apresentaram valores da pressão máxima do corpo do esôfago inferiores a 20mmHg, sendo considerados portadores de megaesôfago avançado, devendo ser tratados por esofagectomia subtotal com esofagogastroplastia ao invés de cardiomiotomia com válvula anti-refluxo. Constatou-se que o estudo manométrico é útil em pacientes portadores de megaesôfago grau III para a escolha do melhor procedimento cirúrgico.

Prevalence of cholelithiasis in patients with chagasic megaesophagus

INTRODUCTION: The prevalence of cholelithiasis in the general population ranges from 9 to 18%. This prevalence is known to be higher in the presence of parasympathetic nerve damage of the biliary tract either due to surgery (vagotomy) or neuronal destruction (Chagas disease). The objective of this study was to evaluate the association of cholelithiasis and chagasic or idiopathic megaesophagus. METHODS: The ultrasound scans of 152 patients with megaesophagus submitted to cardiomyotomy and subtotal esophagectomy surgery were evaluated. The presence of cholelithiasis was compared between chagasic and idiopathic esophagopathy and ultrasound and clinical findings were correlated with age, sex and race. RESULTS: A total of 152 cases of megaesophagus, including 137 with chagasic megaesophagus and 15 with idiopathic megaesophagus, were analyzed. The mean age was 56.7 years (45-67) in the 137 patients with chagasic megaesophagus and 35.6 years (27-44) in the 15 cases of idiopathic megaesophagus, with a significant difference between the two groups (p < 0.0001). The group with chagasic megaesophagus consisted of 59 (43%) women and 78 (56.9%) men, while the group with idiopathic megaesophagus consisted of 8 (53.3%) women and 7 (46.6%) men, showing no significant difference between the groups. Of the 137 patients with confirmed chagasic megaesophagus, 39 (28.4%) presented cholelithiasis versus one case (6.6%) in the 15 patients with idiopathic megaesophagus. CONCLUSIONS: The prevalence of cholelithiasis is high in patients with chagasic megaesophagus and preoperative ultrasound should be performed routinely in these patients in order to treat both conditions during the same surgical procedure.

Surgical site infections in women and their association with clinical conditions

Introduction Surgical site infections (SSIs) can affect body tissues, cavities, or organs manipulated in surgery and constitute 14% to 16% of all infections. This study aimed to determine the incidence of SSIs in women following their discharge from a gynecology outpatient clinic, to survey different types of SSIs among women, and to verify the association of SSIs with comorbidities and clinical conditions. Methods Data were collected via analytical observation with a cross-sectional design, and the study was conducted in 1,026 women who underwent gynecological surgery in a teaching hospital in the municipality of Teresina, in the northeast Brazilian State of Piauí, from June 2011 to March 2013. Results The incidence of SSIs after discharge was 5.8% among the women in the outpatient clinic. The most prevalent surgery among the patients was hysterectomy, while the most prevalent type of SSI was superficial incisional. Comorbidities in women with SSIs included cancer, diabetes mellitus, and hypertension. Conclusions Surveillance of SSIs during the post-discharge period is critical for infection prevention and control. It is worth reflecting on the planning of surgical procedures for patients who have risk factors for the development of SSIs.

Fatal pulmonary thromboembolism in gastrectomy intraoperative procedures by gastric adenocarcinoma: case report

The case of a patient with gastric adenocarcinoma with indication for gastrectomy is reported. The surgery took place without complications. A palliative, subtotal gastrectomy was performed after para-aortic lymph nodes compromised by neoplasm were found, which was confirmed by pathological exam of frozen sections carried out during the intervention. At the end of the gastroenteroanastomosis procedure, the patient began to show intense bradycardia: 38 beats per minute (bpm), arterial hypotension, changes in the electrocardiogram's waveform (upper unlevelling of segment ST), and cardiac arrest. Resuscitation maneuvers were performed with temporary success. Subsequently, the patient had another circulatory breakdown and again was recovered. Finally, the third cardiac arrest proved to be irreversible, and the intra-operative death occurred. Necropsy showed massive pulmonary embolism. The medical literature has recommended heparinization of patients, in an attempt to avoid pulmonary thromboembolism following major surgical interventions. However, in the present case, heparinization would have been insufficient to prevent death. This case indicates that it is necessary to develop preoperative propedeutics for diagnosing the presence of venous thrombi with potential to migrate, causing pulmonary thromboembolism (PTE). If such thrombi could be detected, preventative measures, such as filter installation in the Cava vein could be undertaken.
