Quilopericárdio idiopático primário: relato de caso

O acúmulo de quilo no espaço pericárdico ou quilopericárdio é uma condição que, com maior frequência, ocorre após trauma, cirurgia cardíaca e torácica ou associado a tumores, tuberculose ou linfoangiomatose. Quando não é possível a identificação precisa da etiologia, o quilopericárdio é denominado primário ou idiopático. Essa é uma situação clínica rara. Descrevemos um caso em paciente do sexo feminino, com 20 anos de idade, tratada cirurgicamente. A propósito do caso, apresentamos breve revisão da literatura e comentários sobre quadro clínico, etiopatogenia, exames diagnósticos complementares e opções de tratamento.

Hipertrofia ventricular e mortalidade cardiovascular em pacientes de hemodiálise de baixo nível educacional

FUNDAMENTO: A hipertrofia ventricular esquerda é potente preditor de mortalidade em renais crônicos. Estudo prévio de nosso grupo mostrou que renais crônicos com menor escolaridade têm hipertrofia ventricular mais intensa. OBJETIVO: Ampliar estudo prévio e verificar se a hipertrofia ventricular esquerda pode justificar a associação entre escolaridade e mortalidade cardiovascular de pacientes em hemodiálise. MÉTODOS: Foram avaliados 113 pacientes entre janeiro de 2005 e março de 2008 e seguidos até outubro de 2010. Foram traçadas curvas de sobrevida comparando a mortalidade cardiovascular, e por todas as causas dos pacientes com escolaridade de até três anos (mediana da escolaridade) e pacientes com escolaridade igual ou superior a quatro anos. Foram construídos modelos múltiplos de Cox ajustados para as variáveis de confusão. RESULTADOS: Observou-se associação entre nível de escolaridade e hipertrofia ventricular. A diferença estatística de mortalidade de origem cardiovascular e por todas as causas entre os diferentes níveis de escolaridade ocorreu aos cinco anos e meio de seguimento. No modelo de Cox, a hipertrofia ventricular e a proteína-C reativa associaram-se à mortalidade por todas as causas e de origem cardiovascular. A etiologia da insuficiência renal associou-se à mortalidade por todas as causas e a creatinina associou-se à mortalidade de origem cardiovascular. A associação entre escolaridade e mortalidade perdeu significância estatística no modelo ajustado. CONCLUSÃO: Os resultados do presente trabalho confirmam estudo prévio e demonstram, ademais, que a maior mortalidade cardiovascular observada nos pacientes com menor escolaridade pôde ser explicada por fatores de risco de ordem bioquímica e de morfologia cardíaca.

Occurrence of Odontogenic Infections in Patients Treated in a Postgraduation Program on Maxillofacial Surgery and Traumatology

This study assessed the occurrence and characteristics of oral and maxillofacial infections in patients treated at a Brazilian oral and maxillofacial emergency service during a 7-year period. The clinical files of all patients treated at the Oral and Maxillofacial Surgery and Traumatology Service of the Aracatuba Dental School, São Paulo State University, Brazil, between 2002 and 2008 were reviewed. From a population of 3645 patients treated in this period, the study sample consisted of 93 subjects who presented odontogenic infections. Data referring to the patients' sex, age, medical history, and the etiology, diagnosis, complications, drug therapy/treatment, and evolution of the pathologic diseases were collected and analyzed using the Epi Info 2000 software. of these patients, 54 were men (58.1%) and 39 were women (41.9%). Most patients were in the 31- to 40-year-old (20.7%) and 21- to 30-year-old (19.6%) age groups. The most frequent etiology was pulp necrosis due to caries (80.6%). Regarding the treatment, antibiotics were administered to all patients, surgical drainage was done in 75 patients (82.4%), and 44 patients (47.3%) needed hospital admission. First-generation cephalosporin alone or combined with other drugs was the most prescribed antibiotic (n = 26) followed by penicillin G (n = 25). Most patients (n = 85, 91.4%) responded well to the treatment. Five cases had complications: 3 patients needed hospital readmission, 1 case progressed to descending mediastinitis, and 1 patient died. Odontogenic infections can be life-threatening and require hospital admission for adequate patient care. Complications from odontogenic infections, although rare, may be fatal if not properly managed.

Tratamiento Quirúrgico de Mesiodens en Odontopediatría

Supernumerary teeth are a relatively frequent disorder of odontogenesis that can interfere with the development of the germs teeth. This pathology is most common in the maxillary anterior area, called mesiodens, and their prevalence is generally reported to occur more frequently in male than female, in a ratio of 2:1. The aim of this article was to report the clinical procedures performed in the Clinic of Pediatric Dentistry at the Araraquara School of Dentistry when the presence of two mesiodens, radiographically shown, caused retention of permanent anterior teeth, resulting in esthetic and funcional disturb. All the surgical procedures, etiology and the importancy of the early diagnostic for the appropriate treatment was detailed described.

Treatment and complications of orbito-zygomatic fractures

The aim of the present study was to analyze the etiology, type and treatment employed in the orbito-zygomatic fractures (OZ). Also, postoperative complications are described and correlated with the type of treatment used. Fifty patients with OZ fractures were evaluated. Orbital fractures in which the zygomatic bone was not involved were excluded. Epidemiologic data and characteristics of treatment such as the type of material used for osteosynthesis, number of anatomical sites on which rigid internal fixation (RIF) was applied, surgical approaches and associated complications were recorded. The main causes of trauma were motorcycle and bicycle accidents, constituting 52% of the sample. The osteosynthesis system used was the 2.0 mm, except in four patients in whom the 1.5mm system was used for fixation at the infra-orbital rim. A total of 18% of the patients required reconstruction of the internal orbit and in all cases titanium mesh was used. 46% of the patients received RIF in three anatomical sites, most in the fronto-zygomatic suture, infra-orbital rim and zygomatic-maxillary buttress. The most frequent complication was paresthesia of the infra-orbital nerve (34 patients, 68%). Other findings were also discussed with the intent of better understanding the treatment of the OZ fractures.

Displasia ectodérmica hipohidrótica: un síndrome de interés para la odontología

Hypohidrotic ectodermal dysplasia (HED) is a rare disease of genetic etiology. The most frequent form is of recessive linked to X-chromosome inheritance with affected male and female carriers. It can occur through autosomal mutations, of the gene EDA1 gene being responsible for the majority of the cases. It is characterized by the triad: hypohidrosis, oligodontia and hypotrichosis. We present two cases of patients with HED in which we observed characteristic signs of this syndrome: delicate skin, sparce hair, eyebrows and eyelashes, periorbital wrinkles, perioral and periorbital hyperpigmentation, prominent lips, in addition the patient in case 2 also present the depressed nasal bridge. We also found decreased salivary and lacrimal secretion and maxillary hypoplasia in both cases. At the oral examination in case 1 the upper right and left deciduous canines and lower right deciduous canine were present, and in case 2 the upper and lower (right and left) deciduous canines and two upper (one right and other left) permanent incisors were present with altered morphology, all of these dental elements were healthy. The early dental treatment of patients with HED, especially in the presence of oligodontia, as observed in our cases, is important not only to provide a better quality of life for these patients in the short term, but also an attempt to minimize the changes in facial growth to which these patients are subject.

Imagen de hipertrofia bilateral del proceso coronoides mandibular a través de la tomografía computarizada cone-beam

The hypertrophy of the mandibular coronoid process is a rare condition, progressive and of unknown etiology, characterized by the over development of the coronoid process determining their size increased, resulting in progressive and painful limitation of mouth opening. The mandibular hypomobility is a present symptom in several diseases and associates it to a specific cause requires detailed clinical and imaginologic examination. The cone-beam computed tomography has the potential to provide complementary informations above than conventional radiography. It also has the advantage of eliminate overlaps, provide high resolution image, helping not only in diagnosis, but also in planning the surgical procedure. Here we report a case of male patient, who appeared at the clinic for an evaluation of a trismus. He had no pain, only discomfort for progressive limitation of mouth opening. On physical examination, only a limited mouth opening has been found. Although the movements of laterality and protrusión were posible, they were very limited. Cone-beam computed tomography examination was performed, that showed an image compatible with bilateral hypertrophy of the mandibular coronoid process.

Estresse no ambiente de trabalho

Stress relates to the broad and generalized body's responses to various environmental, physical and social situations. It is the force that drives the emotions and motives (desires), but is also the cause of the wear and tear of human existence. This study aims to investigate the stressors in administrative technical servers Univ. Estadual Paulista - UNESP, Bauru, as well as on companies providing service within the perimeter of the campus. Was used as a methodology, literature and field research, a questionnaire was applied in order to reach those goals. The profiles of employees who participated in the survey were: both sexes, adults, young people with different educational levels, varying levels of marital and socioeconomic status. The main stressors mentioned by the employees were: workload, dissatisfaction in the workplace, pressure boss or colleagues, as they bring consequences, fatigue or drowsiness, affecting the work environment and mostly family. Physical symptoms of stress are fatigue, difficulty relaxing and headache, and backache. And the psychological symptoms are verbalized concern, agitation, aggression, dissatisfaction, and forgetfulness and feeling of lack of time. It was concluded that these factors negatively affect the quality of life in the work of these employees, interfering with your work, family and socio-emotional life.

Onicodistrofia lupoide simétrica canina: relato de caso

Symmetric lupoid onychodystrophy, or lupoid onychitis, is a multifactor immune-mediated onychopathy. The aim of the present study is to report the occurrence of lupoid onychitis in a two year-old mongrel dog helped at the Small Animal Dermatology Service of Sao Paulo State University Veterinary Hospital, in Botucatu, São Paulo. The animal presented lameness, onycholysis in five digits, paronychia, onychomadesis, nail softening and leuchonychia, as well as melicerous crusts in interdigital spaces and nailbeds. No non-dermatological systemic symptoms were observed. Complementary exams were negative for parasites or fungi. After 15 days of treatment there was partial recovery followed by recurrence. Onychectomy was performed in two digits for histopathological examination and fungal culture, which was negative. Histopathology was consistent with lupoid onychitis, reinforcing the importance of this complementary exam.

Doença cerebelar em cães e gatos

Diseases of the cerebellar system are common in small animals, and result in a clinical syndrome characterized by hypermetria, base-wide stance and intentional tremors of the head and body. All movements of the limbs are spastic and awkward. The neurological examination assists in the localization of lesions restricted to the cerebellum or in the detection of disorders relating to other parts of the nervous system, which characterizes a multifocal disease process. Neurological disorders in dogs and cats may suggest a very extensive list of differential diagnoses, since they may be caused by infectious, degenerative and traumatic processes, among others. The possible etiologies for cerebellar syndrome include: aplasia and hypoplasia, abiotrophy, cancer, vascular stroke and inflammatory disorders. The aim of this paper is to review the clinical signs that aid in the location of the cerebellar lesion and discuss the possible causes of this syndrome in dogs and cats.

Síndrome da apnéia obstrutiva do sono: diagnóstico e tratamento

The Syndrome Obstructive Sleep Apnea (OSA) is defined by recurrent episodes of a total or partial obstruction of the airway during sleep, considered apnea and hypopnea respectively. Considered to be increasing by increasing the number of individuals with a disorder breathing, Being continually increasing the number of individuals with a respiratory disorder, OSA can be considered a public health problem that deserves greater attention in relation to diagnoses and treatments that are being conducted. The objective of this study is through a literature review which should be evaluated during the diagnosis and etiology, consequences and treatment of respiratory disorders not adequately treated. The etiology is multifactorial and may be associated with exogenous factors or pathological and anatomical factors. In addition to the own symptoms interfere with the quality of life of the individual, depending on the intensity, OSA can trigger more serious complications. This is a complex syndrome which may have varying degrees and irreversible consequences to the body. The choice of treatment should be based on clinical conditions, the severity of the apnea, the degree of urgency of treatment and the patient's preferences, but the treatments available will not be fully effective if there are no changes in lifestyle of it. The respiratory disorders can range from a simple nasal obstruction and intermittent obstruction more severe, emphasizing the importance of a complete diagnosis, which must be multidisciplinary, through a team relationship between doctor and dentist.

Fatores de risco pré-operatórios para mediastinite após cirurgia cardíaca: análise de 2768 pacientes

INTRODUÇÃO: A esternotomia mediana longitudinal é a via de acesso mais utilizada no tratamento das doenças cardíacas. As infecções profundas da ferida operatória no pós-operatório das cirurgias cardiovasculares são uma complicação séria, com alto custo durante o tratamento. Diferentes estudos têm encontrado fatores de risco para o desenvolvimento de mediastinite e as variáveis pré-operatórias têm tido especial destaque. OBJETIVO: O objetivo deste estudo é identificar fatores de risco pré-operatórios para o desenvolvimento de mediastinite em pacientes submetidos a revascularização do miocárdio e a substituição valvar. MÉTODOS: Este estudo observacional representa uma coorte de 2768 pacientes operados consecutivamente. O período considerado para análise foi de maio de 2007 a maio de 2009 e não houve critérios de exclusão. Foi realizada análise univariada e multivariada pelo modelo de regressão logística das 38 variáveis pré-operatórias eleitas. RESULTADOS: Nesta série, 35 (1,3%) pacientes evoluíram com mediastinite e 19 (0,7%) com osteomielite associada. A idade média dos pacientes foi de 59,9 ± 13,5 anos e o EuroSCORE de 4,5 ± 3,6. A mortalidade hospitalar foi de 42,8%. Na análise multivariada, foram identificadas três variáveis como preditoras independentes de mediastinite: balão intra-aórtico (OR 5,41, 95% IC [1,83 -16,01], P=0,002), hemodiálise (OR 4,87, 95% IC [1,41 - 16,86], P=0,012) e intervenção vascular extracardíaca (OR 4,39, 95% IC [1,64 - 11,76], P=0,003). CONCLUSÃO: O presente estudo demonstrou que necessidade do suporte hemodinâmico pré-operatório com balão intra-aórtico, hemodiálise e intervenção vascular extracardíaca são fatores de risco para o desenvolvimento de mediastinite após cirurgia cardíaca.

Age influences outcomes in 70-year or older patients undergoing isolated coronary artery bypass graft surgery

Objective: To analyze the results of isolated on-pump coronary artery bypass graft surgery (CABG) in patients >= 70 years old in comparison to patients <70 years old. Methods: Patients undergoing isolated CABG were selected for the study. The patients were assigned into two groups: G1 (age >= 70 years old) and G2 (age <70 years old). The endpoints were in-hospital mortality, acute myocardial infarction (AMI), stroke, re-exploration for bleeding, intraaortic balloon pump for circulatory shock, respiratory complications, acute renal failure, mediastinitis, sepsis, atrial fibrillation, and complete atrioventricular block (CAVB). Results: A total of 1,033 were included in the study: G1 comprised 257 (24.8%) patients G2 776 (75.2%). Patients in G1 were more likely to have in-hospital mortality than in G2 (8.9% vs. 3.6%, respectively; P=0.001), while the incidence of AMI was similar (5.8% vs. 5.5%; P=0.87) in G2. More patients in G1 had re-exploration for bleeding (12.1% vs. 6.1%; P=0.003). Compared to G2, G1 had more incidences of respiratory complications (21.4% vs. 9.1%; P<0.001), mediastinitis (5.1% vs. 1.9%; P=0.013), stroke (3.9% vs. 1.3%; P=0.016), acute renal failure (7.8% vs. 1.3%; P<0.001), sepsis (3.9% vs. 1.9%; P=0.003), atrial fibrillation (15.6% vs. 9.8%; P=0.016), and CAVB (3.5% vs. 1.2%; P=0.023). There was no significant difference in the use of the intraaortic balloon pump. In the forward stepwise multivariate logistic regression analysis, age >= 70 years was an independent predictive factor for higher in-hospital mortality (P=0.004), re-exploration for bleeding (P=0.002), sepsis (P=0.002), respiratory complications (P<0.001), mediastinitis (P=0.016), stroke (P=0.029), acute renal failure (P<0.001), atrial fibrillation (P=0.021), and CAVB (P=0.031). Conclusion: This study suggests that patients of age >= 70 years were at increased risk of death and other complications in the CABG's postoperative period in comparison to younger patients.
