Epidemiological aspects and oral implications of Paracoccidioidomycosis infection: an integrative review

Paracoccidioidomycosis (PCM) is a systemic mycosis caused by the dimorphic fungus Paracoccidioides brasiliensis. It represents a significant infection in South America, occurring mainly in tropical and subtropical countries such as Brazil. Oral mucosal lesions, which are the most important symptom in dentistry, may be the first visible physical manifestation of the disease, often preceding even pulmonary lesions. This study aims to carry out an integrative literature review to identify the main epidemiological aspects and oral implications of Paracoccidioidomycosis (PMC) infection. A search was carried out in the PubMed, LILACS and SciELO databases and, after applying the inclusion, exclusion, eligibility and thematic relevance criteria, 18 articles were selected for analysis in this study. Paracoccidioidomycosis (PCM) is endemic in Brazil and mainly affects middle-aged and elderly men and occurs in rural areas. It is a systemic disease where clinical manifestations are often added to oral lesions. Dentists play a key role in identifying these lesions, in the correct diagnosis and treatment of this disease. Making PCM notification compulsory in Brazil is essential.Paracoccidioidomycosis (PCM) is a systemic mycosis caused by the dimorphic fungus Paracoccidioides brasiliensis.

Cholecystoduodenostomy for Treatment of Biliary Obstruction Secondary to Feline Platinossomosis

Background: Platynosomum spp. it is a trematode that has a predilection for the liver and biliary tissues whose infection is acquired through the ingestion of metacercarian gecko viscera. Felines are the definitive hosts and clinical signs are variable. The diagnosis is through history, hematological and biochemical exams, ultrasound, bile cytology or histopathology. The treatment of choice is cholecystoduodenostomy. This paper aims to report the case of a cat who was treated at the Uberaba Veterinary Hospital with chronic cholangitis secondary to platinosomosis, but there was a transfusion reaction and she died.Case: A 4-year-old, uncastrated SRD cat was treated at the Uberaba Veterinary Hospital complaining of severe episodes of vomiting three days ago, hyporexia and darkened urine. The general clinical examination showed moderate dehydration, jaundice and hepatomegaly. The animal was hospitalized for better investigation of its condition. Increased values of ALT, alkaline phosphatase and all bilirubins were observed. Ultrasound showed liver suggestive of liver disease and steatosis, and gallbladder without alteration. During hospitalization, she remained jaundiced and hypoxic, and the esophageal tube was placed. The initial clinical suspicion was cholangiohepatitis. Liver biopsy and cholecystoduodenostomy were then suggested, with refusal by the tutor. The ultrasound was repeated and showed the same alterations described, besides cholangitis. Stool examination was negative for Platynosomum spp. and positive for Isospora spp. The patient was treated with anthelmintic for three days and received supportive treatment for another week until the tutor authorized cholecystoduodenostomy. During surgery, cholecystocentesis was performed and the parasite Platynosomum spp. in adult form. After four days, a new blood count was done and the animal was still anemic and the blood transfusion was chosen. The patient died within moments of the transfusion procedure.Discussion: Platynosomum spp. it is a trematode whose ultimate host is the domestic felines and inhabits liver, gallbladder and bile ducts causing biliary obstruction and even fibrosis. In the present report, the tutor reports that the cat had several episodes of vomiting and reduced appetite. Feline jaundice is normal in cases where cholestasis causes a two to three-fold increase in bilirubinemia from normal values. The increase was verified in the analyzed feline. Physical examination revealed jaundice and abdominal palpation suggestive of hepatomegaly. Ultrasound suggested cholangiohepatitis. Without improvement, liver biopsy and cholecystoduodenostomy were suggested, with tutor refusal. After repeated ultrasound, the images suggested cholangitis and the stool examination was negative for Platynosomum spp. The definitive diagnosis for this disease is through liver biopsy, visualization of the operated eggs or the adult form of the parasite in feces or bile as suggested in this case. However, in cases where there is total obstruction of the bile ducts, the eggs are not eliminated in the digestive system and the examination may be false negative as in this case. After the exams, the cat was submitted to cholecystoduodenostomy surgery where gallbladder puncture was performed for microscopic evaluation, and the parasite Platynosomum spp. in adult form. Most cats have blood type A, but even when the donor has the same blood type, cross-reaction may occur, so compatibility testing should be performed prior to any transfusion, thus reducing the risk of transfusion reactions. The patient died within moments of the transfusion procedure.

Farmacologia clínica da doença de Parkinson: Clinical pharmacology of Parkinson's disease

As patologias neurodegenerativas cursam com depleção progressiva e irreversível dos neurônios existentes em regiões específicas do cérebro. A Doença de Parkinson (DP) é um protótipo, na qual o extravio neuronal do hipocampo e do córtex resulta em déficit de memória e disfunção cognitiva. O seguinte artigo objetivou descrever de modo narrativo as considerações clínicas da doença de Parkinson que justifiquem a ação farmacológica dos fármacos empregados em sua terapêutica. Atualmente, a intervenção farmacológica e a cirúrgica não são capazes de reverter o quadro clínico, mas evitam a progressão da morbimortalidade da DP. O tratamento é individual, baseado na reação específica, o quadro clínico, resposta farmacológica e aspectos socioeconômicos, ocupacionais e emocionais. A finalidade se baseia em perpetuar a autonomia e funcionalidade, o máximo de tempo possível. A escolha dos fármacos mais apropriados para cada paciente e o início do tratamento e o acompanhamento ao longo da evolução são etapas difíceis. Devido a cronicidade, o tratamento deve continuar por toda a vida, considerando que os fármacos e suas doses mudam com o tempo, o surgimento de efeitos adversos

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
