Resumen: Un hombre de 43 años, sin antecedentes médicos relevantes o factores de riesgo conocidos, desarrolló una probable coinfección sintomática por Legionella pneumophila y hantavirus variedad ...Andes, con la aparición de sintomatología abdominal y respiratoria, progresando hasta disfunción orgánica múltiple con falla respiratoria, miocárdica, renal y endotelial. ¿Estamos ante la primera coinfección descrita? Abstract: A 43-year-old man with no relevant medical history or known risk factors, who developed a symptomatic probable coinfection with Legionella pneumophila and hantavirus Andes lineage, with the appearance of abdominal and respiratory symptoms that progressed to multiple organ dysfunction with respiratory, myocardial, renal, and endothelial failure. Is this the first reported coinfection?
Constraint satisfaction is a simple but powerful tool. Constraints identify the impossible and reduce the realm of possibilities to effectively focus on the possible, allowing for a natural ...declarative formulation of what must be satisfied, without expressing how. The field of constraint reasoning has matured over the last three decades with contributions from a diverse community of researchers in artificial intelligence, databases and programming languages, operations research, management science, and applied mathematics. Today, constraint problems are used to model cognitive tasks in vision, language comprehension, default reasoning, diagnosis, scheduling, temporal and spatial reasoning. In Constraint Processing, Rina Dechter, synthesizes these contributions, along with her own significant work, to provide the first comprehensive examination of the theory that underlies constraint processing algorithms. Throughout, she focuses on fundamental tools and principles, emphasizing the representation and analysis of algorithms. * Examines the basic practical aspects of each topic and then tackles more advanced issues, including current research challenges * Builds the reader's understanding with definitions, examples, theory, algorithms and complexity analysis * Synthesizes three decades of researchers work on constraint processing in AI, databases and programming languages, operations research, management science, and applied mathematics
Background: Bacteria of the Anaplasmataceae family and canine hemoparasitic protozoans transmitted by ticks are common in Colombia due to circulation and biological adaptation of vector Rhipicephalus ...sanguineus sensu lato (s.l.). Objective: To detect the circulation of Ehrlichia canis and Hepatozoon canis in sheltered dogs in three municipalities in southern Aburrá Valley, province of Antioquia, Colombia. Methods: Primers were used to amplify the 16S rRNA associated with the Anaplasmataceae family, dsb for Ehrlichia sp. and 18S rRNA for Hepatozoon sp. Results: Of the 357 samples of venous blood obtained, representing all the sheltered dogs in the study zone, Ehrlichia canis DNA was detected in 2.2% of individuals, showing identity of 100% with previous sequences from the GenBank. Hepatozoon canis showed 8.7% (31/357) prevalence of infection, with 100% identity to genotypes from Japan, Brazil, and Spain. Only one sequence of H. canis exhibited a phylogenic divergence concerning H. canis previously reported in Brazil and the Old World. Conclusions: This study confirms the circulation of E. canis and H. canis in asymptomatic shelter dogs in the south-central zone of the Aburrá Valley, province of Antioquia, Colombia. The present study is the first molecular detection of H. canis in the Province of Antioquia and the third report of canine hepatozoonosis from Colombia, highlighting the importance of considering this agent in veterinary clinic.
Introduction: Tibial stress fractures are a very common condition in military recruits. Our objective is to demonstrate that stress fractures are associated with other diseases. Materials and ...Methods: 42 stress fractures in 34 patients were retrospectively evaluated. Every patient had recently joined the Argentine Army and consulted for painful symptoms in the tibia. A clinical and scintigraphic diagnosis of stress fracture was made. Patient data, associated diseases, and risk factors were documented. Inclusion criteria: recent incorporation, same training, age between 16 and 23 years. Trauma, simulators, tumoral pathology, and cases with negative scintigraphy were excluded. Results: We studied 42 stress fractures in 34 patients, 14 were men and 20 were women. The average age was 20 years. There were no significant differences in the number of injuries regarding the affected limb. 64.7% had associated diseases, 73% in women and 27 % in men. Among the women with stress fractures, 80% had associated diseases, compared to 43% for men. Different diseases were found with lower limb varus and valgus imbalances. Varus was the most associated with fractures. Conclusions: A high rate of associated diseases was found in patients with tibial stress fractures with a predominance of lower limb varus imbalances. Associated diseases were more likely to be found in women with stress fractures than in men.
Knowledge of the different imaging tests and their appropriate indications is crucial to establish the diagnosis of temporomandibular disorders, especially in patients with overlapping signs and ...symptoms.
To present and assess the main diagnostic imaging tests for temporomandibular disorders and rationally discuss their indication criteria, advantages, and disadvantages.
Literature review in the Web of Knowledge, PubMed and SciELO databases, as well as manual search for relevant publications in reference lists of the selected articles.
Computed tomography and magnetic resonance imaging were considered the gold standard assessments for the temporomandibular joint to evaluate hard and soft tissues, respectively. Each diagnostic method exhibited distinct sensitivity and specificity for the different subtypes of joint dysfunction.
Selecting an evaluation examination based on its accuracy, safety, and clinical relevance is a rational decision that can help lead to an accurate diagnosis and an optimum treatment plan.
O conhecimento dos distintos exames de imagem e sua correta indicação é fundamental para elaboração do diagnóstico das disfunções temporomandibulares, principalmente em pacientes com grande sobreposição de sinais e sintomas.
Apresentar e avaliar os principais exames de diagnóstico por imagem das disfunções temporomandibulares, além de discutir racionalmente os seus critérios de indicação, vantagens e desvantagens.
Revisão da literatura nas bases de dados Web of Knowledge, PubMed e SciELO, além de busca manual por publicações relevantes nas listas de referências dos artigos selecionados.
Os exames de tomografia computadorizada e ressonância magnética foram considerados “padrão-ouro” para a avaliação dos tecidos duros e moles, respectivamente, da articulação temporomandibular. Cada método de diagnóstico pesquisado apresentou sensibilidade e especificidade distintas para os diferentes subtipos de disfunção da articulação.
Considera-se como racional a indicação fundamentada na acurácia, segurança e relevância clínica do exame a ser solicitado, o que implica na adequada determinação do diagnóstico e do plano de tratamento.
