Relationship of salivary flow of diabetic patients

Diabetes mellitus is a highly prevalent health condition. Its systemic changes cause oral manifestations that may or may not be associated. Objective: To investigate the presence of xerostomia in patients with diabetes. Materials and methods: This study consisted of a series of cases with 22 diabetic patients of the Family Health Strategy (FHS), neighborhood of Dehon, city of Tubarão (SC). A socio-demographic questionnaire was applied, the perception of dry mouth assessed, and the salivary flow measured at rest and after stimulation. To evaluate the association was adopted p<0.05. Results: 77% of patients had dry mouth feeling symptoms compatible with a diagnosis of xerostomia; of these, only 65% had stimulated salivary flow below the reference values (≤0.7ml/min) compatible with hyposalivation also demonstrating the association between xerostomia and hyposalivation. No statistically significant differences occurred between patients using xerostomic medication and decreased salivary flow when stimulated (p=0.15) and dry mouth sensation (p=0.30). Conclusion: The observed diabetic patients have a high prevalence of xerostomia, however, without association with any drug

Clitoridectomy and Urethrostomy in a Pseudohermaphrodite Dog

Background: Hermaphroditism is a rare congenital disease that causes ambiguous sexual features. True hermaphrodites have testicular and ovarian tissue, whereas pseudohermaphrodites have only one type of gonadal tissue, genitalia, but secondary characteristics of the opposite sex. Pseudohermaphrodites are classified as male or female according to their gonads. Treatment of pseudohermaphroditism consists of surgical removal of the gonads including reconstruction of abnormal genitalia, especially if the urethra is involved. Therefore, the objective of this report is to describe a case of a male pseudohermaphrodite in a dog treated with clitoridectomy with urethrostomy.Case: A 7-month-old, mixed-breed dog was referred due to the presence of a flaccid structure similar to a small penis, containing an os clitoris, bulbourethral glands, and urethra protruding from the vulva. Physical examination, complete blood count and serum biochemistry were within normal ranges. Hormonal levels of estradiol, testosterone, and progesterone were 56.39 pg/mL, 127.9 ng/mL, and 0.892 ng/mL, respectively. The abdominal ultrasound and posteriorly the exploratory celiotomy found a normal size prostate and two round organs resembling testicles connected to a uterus-like tubular structure. The patient underwent surgical abdominal exploration that confirmed the ultrasonographic findings and led to gonadohysterectomy. Also, clitoridectomy and urethrostomy were performed to excise the protruded structure and maintain normal urethral patency. The histopathological examination of the clitoris and penis confirmed it was a male genital organ, however, the abdominal structures were compatible with the testicles, epididymis, uterus, and even a broad ligament. These organs are normally found in cases of male pseudohermaphroditism. The testicles were histologically composed of regular seminiferous tubules, single layer Sertoli cells but there were no spermatogenic cells. After ten months of follow-up, the patient was alive, without urination impairment or any other clinical signs.Discussion: The animal presented the protrusion of the penile structure as the sole clinical sign. The reproductive system had a female origin, been possible its masculinization due to high testosterone concentration that induced the development of Wolff ducts, resulting in the formation of the epididymis, deferent ducts, and seminal vesicles. In these cases, it led to an enlarged clitoris. The patient described had hormonal levels compatible with a neutered male/female or a female in anestrus. The clinical signs become evident as the clitoris gets hypertrophied increasing the sensibility, resulting in constant licking of the mucosa, chronic inflammation, and mucopurulent discharge. This patient was diagnosed with male pseudohermaphroditism as it had cryptorchid male gonads along with the uterus and external genitalia of a female dog but containing traces of male genitals such as the os clitoris. Surgery is indicated when there are clinical signs or when the clitoris had an os clitoris or urethra due to an intersex abnormality. The surgical resection of the external male genitalia associated with the excision of the internal reproductive tract treated while preserving the urethra in this animal. Clitorectomy is a simple technique and creates a normal female anatomy ending the clinical signs of the exposed clitoris and improving the quality of life.Clitoridectomy and Urethrostomy in a Pseudohermaphrodite Do

Overview of managed entry agreements : an integrative review towards policy making in Brazil

Resuminho (60 palavras): In order to provide legal and scientific embasement for policy making in Brazil, the aim of this study was to provide a panorama of Managed Entry Agreements around the world. A systematic review was conducted and the information about the agreements were summarized. It was included 25 studies, which described 446 agreements performed in 29 countries. Introduction (100 palavras): Managed Entry Agreements (MEA) are a reality in many countries. They are used as a tool to reduce the impact of uncertainty and the high cost of new drugs by providing access to new technologies under pre-established conditions. In Brazil, the Ministry of Health approved a high-cost technology under performance evaluation, being the first experience in the country. The aim of this study was to conduct a review to identify MEA performed worldwide to provide embasement to inform public health policy making in Brazil, as well as critical considerations surrounding the implementation of performance based agreements. Methods (75 palavras): A review of MEA for health technologies was conducted, using the question ‘What are the health technology managed entry agreements that have being performed around the world?’. The searches were conducted in april 2019, through PUBMED, EMBASE, LILACS and Cochrane Library databases, as well as manual search and gray literature. The selection of studies was performed by two independent reviewers and, in cases of disagreement, solved by a third reviewer. Results (75 palavras): A total of 25 studies were included, describing 446 agreements in 29 countries, being Australia (122), Italy (96), the United States (48) and Scotland (42) more frequent. Financial risk-sharing agreements were the most prevalent (43%). About 95% of the agreements involved medicines - more than half antineoplastic agents. The outcomes assessed and the impact of the agreements were not addressed in most studies, which may be due to the confidentiality character of them. Conclusions (100 palavras): We are likely to see a growth in MEA in the future with the continual launch of new high priced and complex treatments, coupled with increasing demands on available resources. They are an important tool to improve access to innovative and high cost medicines to achieve universal health coverage, although there are critical issues to consider. Besides the embedded confidentiality of most of the agreements, learning from already stablished knowledge, experiences and practices across countries can be a crucial strategy to guide Brazil’s initial experiences in this area

Coalizão talonavicular parcial: Partial talonavicular coalition

Introdução: Coalizão tarsal se refere à fusão congênita entre dois ou mais ossos do mediopé ou retropé, podendo ser de ordem óssea, cartilaginosa ou fibrosa. O subtipo talonavicular é menos prevalente, já que a coalizão talocalcânea e calcâneonavicular são responsáveis por mais de 90% de todos os casos de coalização tarsal. Apresentação do Caso: LVP, feminino, 24 anos, com queixa de dor crônica em pé direito e dificuldade de deambulação há 10 anos. Clinicamente, observou-se dor à mobilização passiva e diminuição da amplitude de movimento, sendo realizada tomografia computadorizada (TC) de pé direito, que evidenciou coalizão talonavicular parcial. Discussão: A apresentação clínica é frequentemente assintomática, favorecendo maior progressão de doença e evolução para complicações que acarretam maior morbidade, como a osteoartrite de mediopé. O tratamento conservador deve ser indicado inicialmente e, em casos de refratariedade à abordagem clínica, recomenda-se a ressecção cirúrgica da coalizão com interposição de enxerto tecidual. Conclusão: A coalizão talonavicular é um subtipo raro e infrequente dentre as coalizões tarsais, sendo uma causa subdiagnosticada de dor crônica no tornozelo e pé, associando-se, portanto, com maior morbidade em virtude do diagnóstico tardio.&nbsp

Enfisema bolhoso idiopático gigante em paciente jovem: Giant idiopathic bullous Emphysema in a young patient

Introdução: O enfisema bolhoso é uma condição crônica e progressiva que ocorre em consequência da degeneração do espaço aéreo pulmonar e formação de uma ou múltiplas bolhas. Apresentação do caso:&nbsp; Homem, 45 anos, caucasiano com ascendência europeia, apresentou-se ao setor de urgência e emergência de um serviço particular da cidade de Brasília, com queixa de dispnéia há aproximadamente 18 meses. Inicialmente associada a atividades físicas intensas, que evoluiu progressivamente no decorrer dos meses. Discussão: Inicialmente, o caso em análise demonstrou características evidentes de enfisema bolhoso gigante (GBE) os quais podem ser percebidos pelos seguintes pontos. A princípio, evidencia-se que o local de trabalho do paciente foi fator fundamental para a evolução do quadro, visto que permanecia por 8 horas diária em uma carvoaria desde a infância. Logo, em decorrência houve o desencadeamento de dispneia aos pequenos esforços, insônia, perda de peso, sensação de aperto no peito e febre. Conclusão: é evidente que o conhecimento científico adequado por parte do médico possibilita a orientação adequada a seu paciente e a elaboração de um plano eficaz, de modo a proporcionar um diagnóstico precoce e a tomada de decisões em tempo hábil. Com isso é possível melhorar o prognóstico do paciente, evitar maiores danos e futuras complicações

Integrative review of managed entry agreements : chances and limitations

Introduction: Managed Entry Agreements (MEAs) consist of a set of instruments to reduce the uncertainty and the budget impact of new high priced medicines; however, there are concerns. There is a need to critically appraise MEAs with their planned introduction in Brazil. Accordingly, the objective is to identify and appraise key attributes and concerns with MEAs among payers and their advisers, with the findings providing critical considerations for Brazil and other high- and middle-income countries. Methods: An integrative review approach was adopted. This involved a review of MEAs across countries. The review question was ‘What are the health technology MEAs that have been applied around the world?’ This review was supplemented with studies not retrieved in the search known to the senior level co-authors including key South American markets. Afterall, involved senior level decision makers and advisers providing guidance on potential advantages and disadvantages of MEAs and ways forward. Results: 25 studies were included in the review. Most MEAs included medicines (96.8%), focused on financial arrangements (43%), and included mostly antineoplastic medicines. Most countries kept key information confidential including discounts or had not published such data. Few details were found in the literature regarding South America. Our findings and inputs resulted in both advantages including reimbursement and disadvantages including concerns with data collection for outcome-based schemes. Conclusion: We are likely to see a growth in MEAs with the continual launch of new high priced and often complex treatments, coupled with increasing demands on resources. Whilst outcome based MEAs could be an important tool to improve access to new innovative medicines there are critical issues to address. Comparing knowledge, experiences and practices across countries is crucial to guide high- and middle-income countries when designing their future MEAs

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio
