"Avaliação do tratamento hormonal e/ou intervencionista por punção nos tumores císticos de ovários" / Evaluation of hormonal treatment and/or intervention through aspiration of ovarian cystic tumors

Chnee, Lúcia Helena 06 September 2006 (has links)
Objetivo: O objetivo deste estudo foi avaliar em mulheres com tumores císticos de ovário, a proporção que, somente com o tratamento clínico e/ou punção, não necessitaram de cirurgia; a influência da medicação e das doenças associadas na indicação de cirurgia e se a punção reduziu significativamente o tamanho dos cistos. Casuística e métodos: Selecionaram-se 71 mulheres com idade entre 19 e 70 anos de idade, portadoras de tumores císticos de ovário maior que 5 cm, com características de benignidade ao ultra-som transvaginal com Doppler colorido e pulsado e com perfil endócrino e marcadores séricos tumorais normais. Foram divididas em cinco grupos: 1) Grupo A: 15 mulheres que fizeram uso de acetato de noretisterona; 2) Grupo B: 13 mulheres que fizeram uso de acetato de medroxiprogesterona; 3) Grupo C: 14 mulheres que utilizaram contraceptivo oral; 4) Grupo D: 15 mulheres que foram tratadas com análogo de GnRH e 5) Grupo E: 14 mulheres que não fizeram uso de medicação. Todos os grupos foram acompanhados por um ano. No final do primeiro trimestre, se o cisto persistiu, foi realizada a punção. No final do segundo trimestre, se houve recidiva do cisto, foi indicada cirurgia. As pacientes tiveram alta após um ano de acompanhamento com o tratamento do cisto concluído. Resultados: Não houve diferenças significantes entre os cinco grupos. Constatou-se que a condição de uso de medicação para doença associada teve influência significativa no resultado dos tratamentos. Verificou-se que a redução do tamanho do cisto com a punção foi efetiva após 9 meses de acompanhamento. Observou-se que 7% das mulheres tiveram indicação direta para cirurgia sem a punção, portanto, a proporção de recidiva da punção foi de 19,3% enquanto a porcentagem de mulheres que não fizeram a cirurgia foi de 73,2%. Conclusão: A proporção de mulheres que responderam adequadamente somente com o tratamento clínico e/ou a punção, não necessitando pois de cirurgia foi de 73,2%. A influência da medicação/ doença associada no tratamento não cirúrgico foi significativa. A redução do tamanho dos cistos benignos em função do tratamento instituído incluindo a punção foi significativa, a qual foi observada após 9 meses de tratamento. / Objectives: To evaluate the rate of women with ovarian cystic tumors submitted to diferent regimens of hormonal treatment and/or aspiration that didn’t need surgery. To access the effectiveness of ovarian cyst aspiration guided by ultrasonography (USG) and to study the influence of medication and associated diseases in the need for surgery. Patients and Methods: Seventy one (71) women, in an age range from 19 to 70 years, diagnosed with ovarian cysts larger than 5 cm in length, with benign aspect, examined using an ultrasonographic transvaginal probe and color Doppler. All the women have been submitted to measurements of ser um tumor markers and hormonal levels. They were grouped in five different categories: 1) Group A: 15 women treated with noretisterone acetate; 2) Group B: 13 subjects treated with medrooxiprogesterone acetate; 3) Group C: 14 patients treated with combined oral contraceptive; 4) Group D: 15 women treated with GnRH analog, and 5) Group E: 15 women with no treatment control). After 3 months, all the patients were reevaluated. In those ones whose cysts remained, cyst aspiration guided by ultrasonography was indicated. After 3 extra months, the women were submitted to a new USG examination and in those whose cysts still remained, surgery was performed. All the patients were followed for one year. Results: There was no significant difference among the groups of hormonal treatment. The use of medication promoted a significant influence in the treatment outcomes. We also noted that the cyst aspiration was effective in reducing the size of the cysts after 9 months of follow up. Seven per cent (7%) of the patients have had immediate indication for surgery. Among those who was submitted to cyst aspiration, 19.3% had to be resubmitted to treatment because of re-incidence of the cyst, whereas, 73.2% avoid the need for surgery. Conclusions: The proportion of subjects treated with hormones and/or cyst aspiration, with no need for surgery, was of 73.2%. The influence of medication/associated disease in the treatments without surgery was significant. The reduction of size of the cysts because of the hormonal and/or aspiration treatment was significant, which was observed after 9 months of therapy.

Responsabilidade civil e nascimento indesejado: prejuízos reparáveis / Tort law and wrongful conception : recoverable damages

Carnaúba, Daniel Amaral 15 April 2016 (has links)
O presente trabalho aborda o tema da responsabilidade civil pelo nascimento indesejado no Direito Brasileiro. Trata-se de um conflito que emerge nos casos em que a falha de um método contraceptivo redunda no nascimento de uma criança, contra a vontade de seus genitores. A primeira parte do trabalho é dedicada ao fato gerador da responsabilidade nessa espécie de litígio, a saber, a culpa médica e o defeito do produto ou serviço de contracepção. Os métodos anticoncepcionais são agrupados em duas categorias: de um lado, os métodos cirúrgicos de esterilização, que envolvem a prestação de um serviço médico; e, de outro, os métodos que empregam dispositivos anticoncepcionais fabricados industrialmente, isto é, os produtos contraceptivos. A segunda parte do trabalho discorre sobre as implicações éticas da reparação do nascimento indesejado. De fato, a indenização fundada no nascimento de um filho traz à tona uma série de considerações relativas à dignidade da criança e ao valor das relações parentais. O trabalho procura apontar em que medida o nascimento de uma criança pode ser interpretado como um prejuízo legítimo experimentado por seus pais. Conclui-se que a reparação integral do nascimento indesejado é necessária para a afirmação da autonomia reprodutiva das vítimas de contraceptivos defeituosos. A análise das soluções controversas adotadas no Reino Unido e na França onde os tribunais afirmaram que apenas o nascimento de uma criança deficiente pode ser considerado um prejuízo reparável revela que o direito dos pais à reparação não pode ser subordinado às condições de saúde da criança nascida / This thesis is an inquiry into wrongful conception claims under Brazilian Tort Law. This type of lawsuit arises out of cases involving failure of contraceptive methods, causing the birth of a child against the parents desire. The first part of the thesis addresses the basis of liability in wrongful conception claims, namely, medical malpractice and defect of products or services. Contraceptive methods are grouped into two categories: on one side, surgical methods of sterilization, that rely upon the supply of medical services; on the other, contraception methods that employ manufactured devices, that is, contraceptive products. The second part of the thesis discusses the ethical implications of awarding damages in wrongful conception claims. Compensation based on the birth of a child raises a series of issues concerning the child\'s dignity and the value of parental relationships. It is argued that full compensation is necessary in order to reaffirm the reproductive autonomy of the victims of defective contraceptive methods. The analysis of controversial solutions adopted in United Kingdom and France where courts have stated that only the birth of a disabled child is a recoverable damage leads to the conclusion that the chillds health condition cannot be a requirement for his parents right to compensation.

Avaliação da atividade da unidade epidermo-melânica e do dano dérmico no melasma

Brianezi, Gabrielli January 2016 (has links)
Orientador: Hélio Amante Miot / Resumo: A patogênese do melasma, especialmente o papel dos queratinócitos e fibroblastos no desenvolvimento e manutenção da doença não é bem compreendida. Alterações dérmicas como dano estrutural à zona de membrana basal, melanócitos em pêndulo, elastose solar, celularidade, proliferação vascular, além da expressão de mediadores inflamatórios, fatores de crescimento, expressão epitelial de melanocortina e receptores dos hormônios sexuais; sugerem interação entre a unidade epidermo-melânica e a derme na fisiopatologia do melasma. A pigmentação melânica da pele pode ser estimulada por diferentes vias de sinalização, sendo a radiação ultravioleta, citocinas dérmicas e inflamação epidérmica, os modelos mais usuais. Neste estudo, objetivamos comparar a morfologia nuclear e a textura da cromatina entre queratinócitos basais no melasma facial e pele adjacente, investigar a ativação das diferentes vias de estímulo à pigmentação, além do envolvimento da derme, com foco na zona de membrana basal e colágeno, no melasma facial. Para a sua execução, foram coletados pares de biópsias faciais (2mm) de mulheres adultas com melasma e de pele adjacente (<2 cm). Processaram-se para coloração de PAS e picrosirius red; imunofluorescência para p53, p38, IL- 1α, αMSH, MC1R e COX2; imunoistoquímica para Melan-Acontracorada com PAS; Microscopia Eletrônica de Transmissão, além de cultura primária de fibroblastos para real-timePCR array e marcação para SA-β-gal. Foram avaliados: núcleos de quer... (Resumo completo, clicar acesso eletrônico abaixo) / Abstract: The melasma pathogenesis, specially the role of keratinocytes and fibroblast in the disease development and maintenance are not completely understood. Dermal alterations such as basal membrane structural damage, pendulous melanocytes, solar elastosis, cellularity, vascular proliferation, in addition to the expression of inflammatory mediators, grow factors, epithelial melanocortin and sexual hormones receptors, suggest there is an interaction between the epidermal melanin unit and dermis in melasma physiopathology. The melanin skin pigmentation can be stimulated by different signaling pathways. UVR, dermal cytokines and epidermal inflammation are the most common models. These study aims to compare the nuclear morphology and chromatin texture in basal keratinocytes between melasma and adjacent skin, to investigate the activation of different pigmentation signaling pathways, and the dermal involvement, focusing on basal membrane zone and collagen. Therefore, facial skin biopsies (2 mm) from women were taken from melasma and normal skin (<2 cm apart) and processed for PAS and picrosirius red; immunofluorescence for p53, p38, IL-1α, αMSH, MC1R and COX2, immunohistochemistry for Melan-A counterstaining with PAS, and transmission electronic microscopy. Furthermore, primary fibroblast culture for real-timePCRarray and SA-β-gal staining. The nuclei of basal keratinocytes were evaluated as nuclear morphometry and chromatin texture; the fluorescence intensity was quantified in the epid...

Role of contraception in HIV prevention

Lufuluabo, Ngeleka Albert 03 1900 (has links)
Thesis (MPhil)--Stellenbosch University, 2013. / ENGLISH ABSTRACT: Reproductive health of people living with HIV/AIDS is a significant public health issue because of its associated risks of HIV transmission to both, the baby and the sexual partner. Provision of effective contraceptive to HIV-positive women is a proven prevention strategy, and can help prevent unintended pregnancy and other sexually transmitted infections. Unmet need for contraception in developing world and rates of unintended pregnancies among women living with HIV remain highly prevalent. The objectives of this study were to identify the current knowledge of HIV-positive women on existing contraceptive methods, determine their current contraceptive practices, identify barriers to contraception use, and provide recommendations on how contraception uptake can be improved among these women in Kasane. A cross-sectional study using qualitative technique was used among twenty five (25) participants at Kasane Primary Hospital. In-depth interviews were conducted with the help of research assistants for data collection. Excel Microsoft Office Software was used for socio-demographics data entry and analysis, and qualitative data were analysed manually using descriptive statistics. Main reasons for low uptake of contraception were desire for children, partner refusal, side effects, and socio-cultural and religious factors. Contraception prevalence was 56 % and condom was the most used contraceptive method (36%). whereas the rate of unintended pregnancies was 60% . Knowledge of contraception was high (100%) but limited proportion of participants (12%) had an expended understanding of contraception as a HIV prevention strategy. Most women living with HIV prefer to space, limit or stop childbearing but do not use any contraceptive method and found themselves with unintended pregnancy. Despite the good knowledge about contraception among participants, the uptake remained low. About half (44%) of the women interviewed were not on any contraceptive method. The choice to use contraception interferes with many factors and the desire to fulfil the primary reproductive intention of men and women, including those living with HIV, mostly override this choice. There is need for a strategic integrated approach that conveys HIV prevention messages and discusses the importance of planning a pregnancy. Thus promoting dual protection among women living with HIV. / AFRIKAANSE OPSOMMING: Die voortplantingsgesondheid van mense wat met MIV/vigs leef, is ‘n belangrike openbaregesondheidskwessie, aangesien voortplantingsgesondheid verband hou met die gevaar van MIV-oordrag na babas sowel as seksmaats. Daar is al bewys dat ander seksueel oordraagbare siektes sowel as onbeplande swangerskappe voorkom word as doeltreffende voorbehoedmiddels verskaf word aan vroue wat MIV-positief is. Dit behoefte aan voorbehoeding in ontwikkelende lande bly egter baie dikwels agterweë, en ‘n groot persentasie vroue wat met MIV leef, raak onbepland swanger. Die doel met hierdie ondersoek is om vas te stel wat vroue wat MIV-positief is, tans oor bestaande voorbehoeding weet, watter voorbehoedingsmetodes hulle tans gebruik en watter struikelblokke daar vir die gebruik van voorbehoeding is, en om voorstelle te maak oor hoe ʼn groter persentasie van hierdie vroue in Kasane oortuig kan word om voorbehoedmiddels te gebruik. ‘n Deursnee-studie wat met behulp van kwalitatiewe tegnieke by die Kasane Primêre Hospitaal uitgevoer is, het vyf en twintig (25) deelnemers betrek. Met die hulp van navorsingsassistente is diepte-onderhoude gevoer om inligting in te samel. Microsoft Office se Excel-sagteware is gebruik om sosio-demografiese inligting in te voer en te ontleed, en kwalitatiewe inligting is met verwysing na beskrywende statistiek met die hand ontleed. Die vernaamste redes vir die trae gebruik van voorbehoeding was die begeerte na ‘n kind, die teenstand van seksmaats, die newe-effekte, en sosio-kulturele en godsdienstige oorwegings. Daar is bevind dat 56% van die deelnemers voorbehoeding gebruik, dat kondome die algemeenste voorbehoedmiddel is (36%) en dat 60% van alle swangerskappe ongewens was. Die deelnemers was almal oor voorbehoeding ingelig (100%), maar slegs ‘n klein persentasie (12%) het ook geweet dat voorbehoedmiddels ‘n voorkomingstrategie vir MIV-infeksie is. Die meeste vroue wat met MIV leef, verkies om swangerskappe te versprei, te beperk of te verhoed, maar gebruik geen voorbehoedmiddels nie en het dus onbepland swanger geraak. Hoewel die deelnemers goed ingelig was oor voorbehoeding, het min van hulle dit gebruik. Ongeveer die helfte (44%) van die vroue met wie onderhoude gevoer is, het geen voorbehoeding gebruik nie. Die keuse om ‘n voorbehoedmiddel te gebruik, word beïnvloed talle ander faktore, en mans en vroue se primêre begeerte om voort te plant – ook al leef hulle met MIV – weeg gewoonlik swaarder as hierdie keuse. Daar is ‘n behoefte aan ‘n strategiese, geïntegreerde benadering wat boodskappe oor MIV-voorkoming oordra en wat tuisbring hoe belangrik dit is om swangerskappe te beplan. Sodoende sal vroue wat met MIV leef, tweedoelige beskerming kry.

Knowledge, perceptions and attitudes regarding contraception among secondary school learners in the Limpopo Province

Netshikweta, Mutshinyalo Lizzybeth 11 1900 (has links)
This study explored knowledge, perceptions and attitudes regarding contraception and contraceptive practices among secondary school learners in the Limpopo Province. Self-administered questionnaires were completed by 612 Grade 8 and 332 Grade 12 learners from 24 randomly selected secondary schools. The study found that permissive attitudes prevailed towards sex, characterised by casual sexual activities commencing at 12 years of age. The availability of contraceptive and termination of pregnancy (TOP) services did not enable learners to utilise them, because of social, cultural, financial and service barriers. Most learners were sexually active without being knowledgeable about contraceptives, emergency contraceptives and TOP services. Two workshops conducted with learners produced similar results to those obtained from the completed questionnaires. Semi-structured interviews conducted with nurses, providing contraceptive and TOP services in the Limpopo Province, also substantiated the findings from the questionnaires. Secondary school learners in the Limpopo Province require more knowledge about and ready access to contraceptives to enable them to delay child bearing until they are emotionally, financially and physically ready for these responsibilities. Nurses and teachers in this province can enhance the learners' contraceptive knowledge and utilisation to help learners make better informed decisions about their own and their future children's lives. / Health Studies / D.

Abortion: social implications for nurses conducting termination of pregnancies in East London

Naicker, Sumithrie Sasha January 2004 (has links)
Abortion is a highly controversial subject that has again come into the spotlight in South Africa due to the legalisation of abortion on demand in 1996. The results of various studies conducted since the Choice on Termination of Pregnancy Act 92 of 1996 was implemented, have indicated that abortion providers have met with a great deal of negativism and ostracism. This study focused on the implications of abortion work on nurses' social relationships with family, friends, colleagues and their communities. Recent literature was reviewed on the subject. The researcher however, found little information on this specific aspect of abortion. The study was conducted with abortion nurses from two government designated hospitals in the East London area responsible for abortion services. Thus, results cannot be generalised. This is a qualitative study that aimed at obtaining firsthand information regarding the personal experiences of abortion nurses. A non-probability sampling technique was used viz. criterion sampling. The Interview Guide Approach was used whereby in-depth, semi-structured interviewed were conducted with the guidance of a set of questions in the form of an Interview Schedule. The ten respondents were asked to share their recommendations as to possible measures that could address the challenges mentioned during their interviews. The researcher came to the conclusion that nurses' social relationships and lives are definitely impacted by abortion work. This impact is largely negative as the majority of respondents experience labelling, stigmatization and ostracism from family, friends, and their colleagues. Abortion nurses also experience a lack of social support, ambivalent feelings with regard to abortion, and a range of negative emotions ranging from stress and depression to frustration and anger. A number of repeat abortions are being done and there seems to be a general lack of contraception. The need exists for nurses to go to Value Clarification Workshops and also to get support in terms of compulsory, continuous, counselling. Separate wards should be set up for abortions whilst sex education should be included in school curriculums at both primary and secondary schools. Family planning and facts about the abortion process should also be included in these sex education programmes. Overall. the need exists for family planning initiatives to promote contraception and deter women from using abortion as a means of contraception. As this study reveals, conducting abortions has come at a great cost for the majority of nurses who lack social support and bear the brunt of anti-abortion sentiment expressed by significant others in their lives. The latter being the people who would normally be the one's they would turn to for help, counsel, support and assistance

Emergency contraception in Addis Ababa : practice of service providers

Lemma, Dawit Assefa 06 1900 (has links)
A quantitative, descriptive, explorative, contextual study was conducted to determine pharmacists and drug vendors' level of knowledge, attitude towards and practice on Emergency Contraceptive (ECl in Addis Ababa. Forty licensed service providers in Addis Ababa were randomly selected during 2008 and interviewed using a structured interview schedule. Data were analysed using a computer software package. The findings revealed that although these service providers were knowledgeable on the purpose and dOSing schedule of EC, they lacked knowledge on side-effects, contra-indications, and types of ECs. Most respondents portrayed a subjective attitude towards easy EC access of especially adolescent girls, since they believed that it will encourage promiscuity and unprotected intercourse. Their knowledge and practice need to be improved, as it has a direct effect on potential users and reducing unwanted pregnancies among young. / Health Studies / M.P.H. (Health Sudies)
