Mucocele of the glands of Blandin-Nuhn-clinical, pathological, and therapeutical aspects

Purpose: This study aims to review anatomical, clinical, and pathological concepts as well as to discuss the most adequate therapeutic approach to the mucoceles of the glands of Blandin-Nuhn. Discussion: The glands of Blandin-Nuhn are localized in the ventral part of the tongue, next to the apex in the lingual median plane. Development of a mucocele in this site is rarely seen; besides, as the glands of Blandin-Nuhn are not encapsulated and are directly overlapped to the muscle tissues, their manipulation tends to be different from the other oral mucoceles. Conclusion: As Blandin-Nuhn mucoceles are uncommon and their clinical appearance could be similar to other lesions, it is important that health professionals know their clinical and histopathological features to avoid having them misdiagnosed. © 2010 Springer-Verlag.

Clinical diagnosis and histological analysis of vocal nodules and polyps

Recent studies emphasize the importance of the clinical-histology correlation in laryngeal pathologies. Objective: To compare the ENT diagnosis with the pathology diagnosis one of 132 surgical specimens, from 119 patients with vocal nodules and polyps. Method: Retrospective study. We investigated the paraffin blocks corresponding to the lesions of the operated patients. We made new histology cross-sections, totaling 396 new slides, divided into three groups: hematoxylin and eosin, Gomori trichrome and PAS. We analyzed the following histological parameters: epithelium, lamina propria, basement membrane, vascular changes. We compared the laryngological and pathological diagnoses, and we did the statistical analysis, checking the predominant histological aspects in each lesion. Results: There was an agreement between the clinical and pathological diagnoses in 123 (93.18%) of 132 lesions analyzed (42.42% nodules and 50.76% polyps). In the histological parameters we found: epithelial changes such as nodules hyperplasia (82.14%) and polyp atrophy (31.34%). Lamina propria: edema in polyps (71.43%), fibrosis in the nodules (57.14%). Basement membrane: thickened nodules (100%), thin/no change in polyps (100%). There was a predominance of vascular changes in the polyps. Conclusion: We found a high correlation between the ENT diagnosis and the pathology report. Histopathologically, the nodules presented with predominantly epithelial changes, lamina propria and basement membrane fibrosis, while the polyps by changes strictly on the lamina propria and vascular aspects.

Epidemiological aspects of retrovirus (HTLV) infection among Indian populations in the Amazon Region of Brazil

O HTLV foi descrito inicialmente associado a uma leucemia no Japão e a uma doença neurológica presente no Caribe. Logo foi evidenciado que o HTLV-II era endêmico entre Ameríndios e, particularmente, entre Índios brasileiros. A Amazônia brasileira é a maior área endêmica para o vírus e dessa forma, permitiu que fossem realizados vários estudos relacionados com a sua biologia, a busca de doença, informações epidemiológicas que incluíram uma bem definida distribuição geográfica, a definição dos modos de transmissão e manutenção do vírus em comunidades pequenas, epidemiologicamente fechadas, assim como contribuições para o diagnóstico laboratorial da infecção. Um novo subtipo molecular, denominado HTLV-IIc, foi adicionalmente descrito baseando-se no sequenciamento genético do vírus e na análise filogenética. Esse subtipo está presente em outras áreas do país, indicando que o HTLV também funciona como um marcador precioso das migrações humanas nas Américas no passado e um provável marcador dos costumes das populações atuais. O outro retrovírus humano, o HIV, ainda não é prevalente nas comunidades indígenas, apesar de que elas podem ser facilmente alcançadas em virtude das inúmeras facilidades de transmissão para o vírus.

Leprosy: review of the epidemiological, clinical, and etiopathogenic aspects - Part 1

Leprosy is caused by Mycobacterium leprae and has been known since biblical times. It is still endemic in many regions of the world and a public health problem in Brazil. The prevalence rate in 2011 reached 1.54 cases per 10,000 inhabitants in Brazil. The mechanism of transmission of leprosy consists of prolonged close contact between susceptible and genetically predisposed individuals and untreated multibacillary patients. Transmission occurs through inhalation of bacilli present in upper airway secretion. The nasal mucosa is the main entry or exit route of M. leprae. The deeper understanding of the structural and biological characteristics of M. leprae, the sequencing of its genome, along with the advances in understanding the mechanisms of host immune response against the bacilli, dependent on genetic susceptibility, have contributed to the understanding of the pathogenesis, variations in the clinical characteristics, and progression of the disease. This article aims to update dermatologist on epidemiological, clinical, and etiopathogenic leprosy aspects.

Leprosy: a review of laboratory and therapeutic aspects - Part 2

Leprosy is a chronic infectious condition caused by Mycobacterium leprae(M. leprae). It is endemic in many regions of the world and a public health problem in Brazil. Additionally, it presents a wide spectrum of clinical manifestations, which are dependent on the interaction between M. leprae and host, and are related to the degree of immunity to the bacillus. The diagnosis of this disease is a clinical one. However, in some situations laboratory exams are necessary to confirm the diagnosis of leprosy or classify its clinical form. This article aims to update dermatologists on leprosy, through a review of complementary laboratory techniques that can be employed for the diagnosis of leprosy, including Mitsuda intradermal reaction, skin smear microscopy, histopathology, serology, immunohistochemistry, polymerase chain reaction, imaging tests, electromyography, and blood tests. It also aims to explain standard multidrug therapy regimens, the treatment of reactions and resistant cases, immunotherapy with bacillus Calmette-Guérin (BCG) vaccine and chemoprophylaxis.

Echocardiographic aspects of hypertrophic cardiomyopathy in a Persian cat: case report

Hypertrophic cardiomyopathy (HCM) is a primary myocardial abnormality characterized by diastolic dysfunction and congestive heart failure of unknown etiology. It is a cardiac disorder most common in cats (Felis catus), and is reported as a rare condition in dogs. There are racial, sex and age predisposition in cats. Clinical signs commonly found are anorexia, nausea, vomiting, acute dyspnea, paresis or paralysis of hind limbs. Radiographic and electrocardiographic exams are critical to understanding the disease, but Doppler echocardiographic imaging is the definitive method for diagnosis. Our objective is to report the appearance and Doppler ultrasonography in a case of hypertrophic cardiomyopathy in a 3-year-old Persian cat.

Echocardiographic and radiographic aspects of tetralogy of Fallot in a Border Collie: case report

Tetralogy of Fallot is a complex cardiac malformation characterized by four anatomical defects: pulmonary valve stenosis, right ventricular hypertrophy, interventricular septal defect and aortic dextroposition. Imaging techniques are useful in the diagnosis of this disease, such as radiography for screening and Doppler echocardiography for a definitive diagnosis. Our objective is to report the radiographic and Doppler echocardiographic aspects of a tetralogy of Fallot case in a 10 month-old Border Collie dog.

Diagnóstico de gestação em cadelas: aspectos radiográficos e ultrassonográficos

The modernization of image equipaments associate to the veterinary professionals qualification allowed an advance in diagnosis veterinary medicine, and, consequently, in premature pregnancy diagnosis in bitches. Currently, owners and creators search for information related to pregnancy detection, fetal development and viability and litter size determination. Through diagnosis methods as radiology and ultrasonography, associated to clinics aspects, the diagnosis of early pregnancy become more acurated and precise, allowing more quality in the accompaniment of prenatal of these bitches. Ultrasonographic exams help the accompaniment of these pregnancies through of visuals recourses, which can supply information related to pregnancy detection, embrionary and fetal development, fetal viability e litter size determination through fetals mensurations. The radiographic study has as principal indication the fetal counting, and has been the most acurated for this analyses. It may be done after the da s after the luteini ing hormone surge, when occurs the fetal mineralization. Due to its importance in the present time and in small animals clinic, the objective of this study is to discuss the main radiographics and ultrassonographics aspects of the diagnosis of pregnancy in bitches

Recursos humanos e materiais na assistência de enfermagem a pacientes de uma unidade de tratamento de queimaduras

The burn is among the leading causes of morbidity and mortality in our society. It shows a great complexity and is hard to treat. Beyond the physical suffering, the burned patient is affected by psychological distress, requiring a high level of knowledge for assistance planning. The Professional Practice Law No. 7498 establishes the nurse as in charge of the client, as leader of the nursing team and as responsable for the management of physical and human resources. The nurse has autonomy to design the quantitative and qualitative picture of the nursing staff and should use the methodologies for their suitability to the real levels of assistance needed. Material resources represent 15 to 25% of total expenditures at health organizations. Therefore, to maintain the care level, nurses must determine the needs, considering the quantitative, qualitative and financial aspects. The study aimed the survey of the human and material resources necessary for nursing care to patients in a Burns Treatment Unit and identify its epidemiological profile and its nursing diagnoses. We collected the data from medical records of hospitalized between July and August, and the nursing diagnoses were classified through the Taxonomy II proposed by the North American Nursing Diagnosis Association (NANDA). The design of the picture of nurses followed the parameters of COFEN Resolution nº 293/2004. We apply the Fugulin's Patients Classification System to establish levels of the required care. The institution's Cost Center provided a spreadsheet with the purchased items, subsequently classified into ABC. Most hospitalized patients were men, aged between 20 and 50. There was a predominance of patiences with minor burned and the most common type of burn was due to fire. The average residence time was 28.71 days, and 88% of the patients were discharged...

Squamous odontogenic tumor: literature review focusing on the radiographic features and differential diagnosis

Since its first publication in 1975, the squamous odontogenic tumor remains the rarest odontogenic lesion, with around 50 cases in the English-language literature in which the microscopic characteristics are frequently very well demonstrated. However, articles which discuss the radiographic aspects are scarce, especially with emphasis on the differential diagnosis. The present treatise proposes an assessment of jaw lesions with the same radiographic characteristics of the squamous odontogenic tumor to clarify the main findings for dental clinicians during routine diagnosis.
