Achievements of the FIGO Initiative for the Prevention of Unsafe Abortion and its Consequences in South-Southeast Asia.

Since 2008, the FIGO Initiative for the Prevention of Unsafe Abortion and its Consequences has contributed to ensuring the substitution of sharp curettage by manual vacuum aspiration (MVA) and medical abortion in selected hospitals in participating countries of South-Southeast Asia. This initiative facilitated the registration of misoprostol in Pakistan and Bangladesh, and the approval of mifepristone for "menstrual regulation" in Bangladesh. The Pakistan Nursing Council agreed to include MVA and medical abortion in the midwifery curriculum. The Bangladesh Government has approved the training of nurses and paramedics in the use of MVA to treat incomplete abortion in selected cases. The Sri Lanka College of Obstetricians and Gynaecologists, in collaboration with partners, has presented a draft petition to the relevant authorities appealing for them to liberalize the abortion law in cases of rape and incest or when lethal congenital abnormalities are present. Significantly, the initiative has introduced or strengthened the provision of postabortion contraception.

Caracterização de aguardente de cana-de-açúcar "grogue de Cabo Verde"

A aguardente de cana é uma bebida de grande importância económica para Cabo Verde, mais concretamente para as ilhas de Santiago, Brava, Nicolau e S. Antão, que apresentam boas condições climáticas para a produção de cana. O consumo tem vindo a crescer em todas as classes sociais e tem a pretensão de conquistar o mercado internacional. Mas isso gera dificuldades para os produtores de aguardente, que muitas vezes enfrentam barreiras para entrar no mercado externo, principalmente devido à qualidade do produto e à falta de padronização desta bebida. Este trabalho teve como objectivo obter uma identidade e qualidade padrão da aguardente de cana em Cabo Verde, portanto, fizeram-se 5 destilados na ESTM os quais foram avaliados sensorialmente quanto à padronização do produto e também quanto à qualidade através de comparação com duas aguardentes feitas por produtores cabo-verdianos. Para isso, foram preparados 40 litros de calda, dividida em 5 lotes de 7,5 litros no alambique, obtendo-se 5 destilados com 450, 470, 565, 300 e 430ml. Determinou-se o grau alcoólico, acidez total, teor furfural e teor de cobre dos destilados realizados na escola e em Cabo Verde. Os valores obtidos do grau alcoólico, acidez total e furfural encontramse dentro dos limites estabelecidos pela lei brasileira, com exceção para o furfural que apresentou um resultado positivo nas amostras dos destilados feitos em Cabo Verde, correspondente a 28,57%. Os valores de acidez total variaram entre 9,38 a 136,87 mg/100 ml (álcool anidrido). O cobre foi determinado através da técnica de espectroscopia de absorção atómica com câmara grafite. As amostras analisadas apresentaram valores de cobre que variaram de 0,406 a 7,380 mgL-1. Das amostras analisadas 71,43% estavam dentro do limite e 28,57 % apresentaram teores de cobre acima do permitido pela legislação. Relativamente à padronização das 5 amostras feitas na escola, demonstrou-se que a estrutura de dados apenas se evidenciou validada para os atributos oleosidade e aroma (p = 0.000 e p = 0.037, respetivamente). Comparando as amostras feitas na escola com as duas de Cabo Verde, mostrou-se que à cor franca (P <0,000) e aceitável (P <0,013), limpidez (P <0,000) brilhante e transparente (P <0,001), as variáveis independentes não exercem influências na variável dependente segundo o modelo proposto.

Association between intratumoral lymphatic microvessel density (LMVD) and clinicopathologic features in endometrial cancer: a retrospective cohort study

Background: Lymph node metastasis in endometrial cancer significantly decreases survival rate. Few data on the influence of intratumoral lymphatic microvessel density (LMVD) on survival in endometrial cancer are available. Our aim was to assess the intratumoral LMVD of endometrial carcinomas and to investigate its association with classical pathological factors, lymph node metastasis and survival. Methods: Fifty-seven patients with endometrial carcinoma diagnosed between 2000 and 2008 underwent complete surgical staging and evaluation of intratumoral LMVD and other histologic variables. Lymphatic microvessels were identified by immunohistochemical staining using monoclonal antibody against human podoplanin (clone D2-40) and evaluated by counting the number of immunostained lymphatic vessels in 10 hot spot areas at 400x magnification. The LMVD was expressed by the mean number of vessels in these 10 hot spot microscopic fields. We next investigated the association of LMVD with the clinicopathologic findings and prognosis. Results: The mean number of lymphatic vessels counted in all cases ranged between 0 and 4.7. The median value of mean LMVD was 0.5, and defined the cut-off for low and high LMVD. We identified low intratumoral LMVD in 27 (47.4%) patients and high LMVD in 30 (52.6%) patients. High intratumoral LMVD was associated with lesser miometrial and adnaexal infiltration, lesser cervical and peritoneal involvement, and fewer fatal cases. Although there was lower lymph node involvement among cases with high LMVD, the difference did not reach significance. No association was seen between LMVD and FIGO staging, histological type, or vascular invasion. On the other hand, low intratumoral LMVD was associated with poor outcome. Seventy-five percent of deaths occurred in patients with low intratumoral LMVD. Conclusion: Our results show association of high intratumoral LMVD with features related to more localized disease and better outcome. We discuss the role of lymphangiogenesis as an early event in the endometrial carcinogenesis.

Identification of fructooligosaccharides in different banana cultivars

Banana has been currently indicated as a good source of fructooligosaccharides (FOS), which are considered to be functional components of foods. However, significant differences in their amounts in bananas have been observed in the literature. This work aims to identify and quantify FOS during ripening in different banana cultivars belonging to the most common genomic groups cultivated in Brazil. Considering that these differences can be due to cultivar, stage of ripening, and the methodologies used for FOS analyses, sugar contents were analyzed by high performance anion exchange chromatography-pulsed amperometric detection (HPAEC-PAD) and gas chromatography-mass spectrometry (GC-MS). An initial screening of eight cultivars (Ouro, Nanicao, Prata, Maca, Mysore, Pacovan, Terra, and Figo) in a full-ripe stage showed that 1-kestose, the first member of the FOS series (amounts between 297 and 1600 mu g/g of DM), was accumulated in all of them. Nystose, the second member, was detected only in Prata cultivar. Five of the cultivars were analyzed during ripening, and a strong correlation could be established with a specific sucrose level (similar to 200 mg/g of DM), which seems to trigger the synthesis of 1-kestose (the low amounts of FOS, below the functional recommended dose, indicates that banana cannot be considered a good source of FOS).

Treatment for low-risk gestational trophoblastic disease: Comparison of single-agent methotrexate, dactinomycin and combination regimens

Objectives. To compare the efficacy of three different standard chemotherapy regimens for low-risk gestational trophoblastic disease according to the FIGO staging system in a single-institute setting. Methods. From 1980 until 2002, we retrospectively reviewed 108 cases with low-risk persistent gestational trophoblastic disease who were treated with first-line chemotherapy. Patients were divided in three groups according to chemotherapy regimen: patients treated with methotrexate (MTX group; n=42), patients treated with dactinomycin (ACT group; n=42) and patients treated with methotrexate and dactinomycin in combination (MACT group; n=24). We compared the number of chemotherapy courses for achieving remission, the duration of treatment, the adverse side effects, the efficacy of the treatment and the need for performing a hysterectomy among the groups Results. The complete remission rates were 69%, 61.4% and 79.1% for methotrexate (MTX), dactinomycin (ACT) and the combination regimen (MACT) treated groups, respectively (p=0.7). The duration of the treatment and the number of chemotherapy courses were similar among the groups (p = 0.2 and p = 0.4, respectively). Adverse side effects rate was reported to be 62.5% in the MACT group, 28.6% in the MTX group and 19.1% in the ACT group (p=0.0003). Second-line chemotherapy was indicated for 30 patients. Hysterectomy was performed in 21 patients overall, and there was no difference among the groups (P=0.6). Conclusion. Our analysis indicates that single-agent chemotherapy regimens are as effective as combination chemotherapy for low-risk gestational trophoblastic disease. Dactinomycin is a less toxic drug and might offer the best cost-effective treatment option. Methotrexate must be considered as the regimen of choice for low resource areas because of the feasibility of its administration. (c) 2007 Elsevier Inc. All rights reserved.

Peritoneal cytology: impact on disease-free survival in clinical stage I endometrioid adenocarcinoma of the uterus

The prognostic significance of positive peritoneal cytology in endometrial carcinoma has led to the incorporation of peritoneal cytology into the current FIGO staging system, While cytology was shown to be prognostically relevant in patients with stage II and III disease, conflicting data exists about its significance in patients who would have been stage I but were classified as stage III solely and exclusively on the basis of positive peritoneal cytology (clinical stage I). Analysis was based on the data of 369 consecutive patients with clinical stage I endometrioid adenocarcinoma of the endometrium. Standard treatment consisted of an abdominal total hysterectomy, bilateral salpingo-oophorectomy with or without pelvic lymph node dissection. Peritoneal cytology was obtained at laparotomy by peritoneal washing of the pouch of Douglas and was considered positive if malignant cells could be detected regardless of the number of malignant cells present. Disease-free survival (DFS) was considered the primary statistical endpoint. In 13/369 (3.5%) patients, positive peritoneal cytology was found. The median follow-up was 29 months and 15 recurrences occurred. Peritoneal cytology was independent of the depth of myometrial invasion and the grade of tumour differentiation, Patients with negative washings had a DFS of 96'7e at 36 months compared with 67% for patients with positive washings (log-rank P < 0.001). The presence of positive peritoneal cytology in patients with clinically stage I endometrioid adenocarcinoma of the endometrium is considered an adverse prognostic factor.

Controle da ferrugem e da broca-dos-ramos da figueira com diferentes fungicidas e inseticidas

Temperaturas e precipitações elevadas favorecem a incidência da ferrugem (Cerotelium fici(Cast.)) e da broca-dos-ramos (Azochis gripusalis (Walker, 1859) (Lepidoptera: Pyralidae)), limitando a produção comercial de figos. O objetivo deste trabalho foi comparar a eficiência de fungicidas e inseticidas alternativos em relação à de produtos convencionais registrados para a cultura. Foram realizados dois experimentos, no delineamento de blocos inteiramente casualizados, com quatro repetições, no setor de fruticultura da Universidade Tecnológica Federal do Paraná, Campus Dois Vizinhos. Para controle da ferrugem, foram utilizados, em 100 L de água, azoxistrobin (10 g), calda bordalesa (1.500 g de cal virgem + 1.500 g de sulfato de cobre) e testemunha (água). No controle da broca-dos-ramos utilizaram-se, em 100 L de água, azadiractina (1.000 mL P.C.), alho (Allium sativum L.) (100 mL P.C.), cinza (20.000 g), extrato de fumo (nicotina) (10.000 mL do preparado), deltametrina (50 mL P.C.), Bacillus thuringiensis Berliner (100 g P.C.), rotenona (1.000 mL P.C.), sabão de coco (1.000 g) e testemunha (água). A calda bordalesa foi o tratamento mais efetivo no controle da ferrugem, promovendo aumento da produtividade e da qualidade dos frutos. A deltametrina promoveu o melhor controle da broca-dos-ramos da figueira. Entre os produtos alternativos testados, o alho foi o mais efetivo no controle dessa praga.

Associação entre paracoccidioidomicose e alcoolismo

A associação entre alcoolismo e paracoccidioidomicose foi avaliada pelo método de caso-controle, comparando-se o hábito de ingestão etílica de 70 doentes com o de outros 70 pacientes hospitalizados por razões diversas e pareados por sexo e idade. Os participantes foram interrogados de maneira padronizada sobre a quantidade, tipo e periodicidade da ingestão de bebidas alcoólicas, duração do consumo e também sobre manifestações de abuso e/ou dependência do álcool. Na forma crônica da micose foi observada proporção significativamente maior de doentes com ingestão média de álcool acima de 60 ml/dia (50,0% x 30,0%) e com preferência por aguardente de cana (89,4% x 68,3%) em relação ao grupo controle, além dos grandes bebedores (>100 ml/dia) mostrarem tendência de reativação da doença durante ou após seu tratamento. Na forma aguda/subaguda da paracoccidioidomicose verificou-se que 64,3% dos consumidores de bebidas alcoólicas já haviam tido um ou mais episódios de embriaguez etílica, versus 17,6% no grupo controle. Os dados sugerem que o alcoolismo seja fator predisponente da paracoccidioidomicose e talvez possa prejudicar sua cura, principalmente da forma crônica da infecção.

Consumo de bebida alcoólica e adiposidade abdominal em doadores de sangue

OBJETIVO: Analisar a associação entre o consumo de bebidas alcoólicas e adiposidade abdominal. MÉTODOS: Estudo transversal com uma amostra de homens doadores de sangue (N=1.235), de 20 a 59 anos, em Cuiabá (MT), realizado de agosto/1999 a janeiro/2000. Os indicadores de adiposidade abdominal foram circunferência da cintura e relação cintura/quadril, ajustados pela adiposidade total. As medidas aferidas foram: peso, estatura, circunferências da cintura e do quadril. O consumo de álcool foi avaliado utilizando-se um questionário sobre tipo, freqüência e quantidade da bebida consumida. A associação entre o consumo de álcool e adiposidade abdominal foi analisada por regressão linear múltipla, com os modelos ajustados para idade, atividade física, tabagismo e adiposidade total. RESULTADOS: Após ajuste, a circunferência da cintura e a relação cintura quadril mantiveram-se associadas positivamente ao consumo de cerveja (p=0,02) e ao total de álcool consumido (p=0,01 e 0,03, respectivamente). O consumo de aguardente mostrou associação somente com a circunferência da cintura (p=0,04). CONCLUSÕES: O consumo de álcool, particularmente de cerveja, associou-se com a localização abdominal de gordura.

Prevalência e Factores de Risco para Síndrome Látex-Frutos em Doentes com Alergia ao Látex

A associação de alergia ao látex e alergia alimentar a frutos e outros vegetais com reactividade cruzada com látex é denominada síndrome látex-frutos (SLF). Não existem estudos que avaliem factores de risco para SLF em doentes alérgicos ao látex, nomeadamente incluindo diferentes grupos populacionais de risco. Objectivo: Investigar a prevalência e factores de risco para SLF. Material e Métodos: Foram estudados 61 doentes alérgicos ao látex, com média etária de 25.9 (±16.6) anos e relação sexo M/F de 0.3/1, pertencendo a diferentes grupos de risco: 15 com espinha bífida (EB), 13 submetidos a múltiplas cirurgias sem EB e 33 profissionais de saúde (PS). A todos os doentes foram efectuados questionário, testes cutâneos por prick (TC) com aeroalergénios comuns e látex(extractos comerciais) e alimentos com reactividade cruzada descrita com látex (extractos comerciais e alimentos em natureza), IgE total sérica (AlaSTAT®, DPC) e IgE específica para látex (UniCAP®, Pharmacia Diagnostics). Definiu-se SLF se história clínica e TC para o alimento positivos. Resultados: A prevalência de SLF nos doentes alérgicos ao látex foi 28% (17). Os alimentos implicados foram castanha-71% (12), banana-47% (8), pêssego-29% (5), abacate e kiwi-24% (4),ananás, maracujá, papaia e espinafre-18% (3), ameixa, manga, melão, tomate e mandioca-12%(2), alperce, figo, uva e pimentão doce-6% (1). Os sintomas clínicos foram anafilaxia-65% (11),urticária-24% (4) e síndrome de alergia oral-12% (2). Os doentes com SLF eram na quase totalidade PS. A prevalência de SLF neste grupo foi 45% (15). Comparando PS com SLF (15) e sem SLF (18), encontrou-se relação entre SLF e níveis mais elevados de IgE específica para látex (mediana: 19.4 vs. 0.6kU/l; p=0.006). Os PS com CAP-classe ≥ 3 tinham SLF em 74%, para 26% nos PS com CAP-classe <3 (p<0.001). Idade, sexo, antecedentes pessoais e familiares de alergia, número de cirurgias, tempo de profissão, atopia e IgE total não foram identificados como factores de risco. Conclusões: A SLF afecta essencialmente os PS alérgicos ao látex, sendo frequente neste grupo; a explicação reside nos diferentes perfis de sensibilização alergénica, relacionados com a via de exposição. A sensibilização ao látex com CAP-classe ≥ 3 foi identificada como factor de risco para SLF nos PS. A SLF revelou-se na maioria dos casos por anafilaxia,realçando a importância desta síndrome potencialmente fatal.

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.

Neuroendocrine Tumours of the Female Genital Tract: a Case-Based Imaging Review with Pathological Correlation

BACKGROUND: Both primary and secondary gynaecological neuroendocrine (NE) tumours are uncommon, and the literature is scarce concerning their imaging features. METHODS: This article reviews the epidemiological, clinical and imaging features with pathological correlation of gynaecological NE tumours. RESULTS: The clinical features of gynaecological NE tumours are non-specific and depend on the organ of origin and on the extension and aggressiveness of the disease. The imaging approach to these tumours is similar to that for other histological types and the Revised International Federation of Gynecology and Obstetrics (FIGO) Staging System also applies to NE tumours. Neuroendocrine tumours were recently divided into two groups: poorly differentiated neuroendocrine carcinomas (NECs) and well-differentiated neuroendocrine tumours (NETs). NECs include small cell carcinoma and large cell neuroendocrine carcinoma, while NETs account for typical and atypical carcinoids. Cervical small cell carcinoma and ovarian carcinoid are the most common gynaecological NE tumours. The former typically behaves aggressively; the latter usually behaves in a benign fashion and tends to be confined to the organ. CONCLUSION: While dealing with ovarian carcinoids, extra-ovarian extension, bilaterality and multinodularity raise the suspicion of metastatic disease. NE tumours of the endometrium and other gynaecological locations are very rare. TEACHING POINTS: • Primary or secondary neurondocrine (NE) tumours of the female genital tract are rare. • Cervical small cell carcinoma and ovarian carcinoids are the most common gynaecological NE tumours. • Cervical small cell carcinomas usually behave aggressively. • Ovarian carcinoids tend to behave in a benign fashion. • The imaging approach to gynaecological NE tumours and other histological types is similar.
