Análise dos índices de variabilidade da frequência cardíaca em jovens obesos

Introdução: A variabilidade da frequência cardíaca (VFC) descreve o comportamento dos intervalos RR que está relacionado às ações do sistema nervoso autônomo (SNA) sobre o nódulo sinusal. Essa pode ser influenciada por diversos fatores dentre eles a obesidade, doença de etiologia multifatorial definida como um acúmulo excessivo de gordura corporal. Objetivo: Avaliar em jovens obesos com idade entre 18 e 23 anos o comportamento autonômico cardíaco, durante o repouso, por meio da análise linear e não linear dos índices da VFC bem como associá-lo a eventos de desconforto músculoesquelético influenciados ou não pela prática regular de exercício físico nessa população. Metodologia: Para a realização deste estudo foram analisados dados de 68 voluntários jovens, de ambos os sexos, distribuídos de forma não randomizada em dois grupos: o G1 constituído por 32 obesos, 20,21 ± 1,66 anos e o G2 por 36 não obesos, 20,8 ± 1,47 anos sendo considerado como critério de classificação dos voluntários o índice de massa corpórea (IMC). O protocolo experimental consistiu da captação da frequência cardíaca batimento a batimento, por meio de uma cinta de captação fixada no tórax do voluntário juntamente com um receptor de frequência cardíaca fixado no punho. Para esta captação o voluntário foi orientado a permanecer em repouso na posição de decúbito dorsal sobre um colchonete, durante 30 minutos, com a respiração espontânea. Além disso, foram aplicados dois questionários, ou seja: versão curta do International Physical Activity Questionaire (IPAQ) - Questionário Internacional de Atividade Física, a fim de classificar o nível de atividade física e o Questionário Nórdico, para detectar eventuais sintomas osteomusculares decorrentes das atividades de vida diária e/ou atividades física. Os índices da VFC analisados foram: análise linear... (Resumo completo, clicar acesso eletrônico abaixo)

Hemangiossarcoma corneal em cão

Hemangiosarcoma is a malignant neoplasm and its corneal presentation is uncommon in the dog. The present work reports a case of primary corneal hemangiosarcoma on a mongrel female dog, 20kg, nine years old with a 2 month history of a mass with progressive growth in the right eye. The ophthalmic examination of the right eye showed blepharospasm, moderated conjunctival hyperemia and the presence of a reddish irregular nodule on the dorsal region of the cornea, occupying approximately 60% of the cornea. The ocular ultrasound revealed that the neoplasm affected only the cornea and the cytological examination diagnosed a malignant mesenchymal neoplasm. The patient was submitted to keratectomy followed by a third eyelid flap. The excised material was sent for histopathological analysis that diagnosed hemangiosarcoma. Fifteen days after surgery the third eyelid flap was removed and the ophthalmic examination revealed recurrence of the tumor, with the mass occupying the entire cornea and part of the bulbar conjunctiva. The patient was submitted to enucleation. No alterations were observed on the abdominal ultrasound and thoracic radiography, showing the primary characteristics of the disease. Two years after surgery the patient is clinically healthy, without any signs of recurrence or metastasis. Despite the surgical excision of the tumor with free margins, in cases of hemangiosarcoma with aggressive behavior, the enucleation should be considered as a viable option for a successfull therapeutic protocol and better prognosis of the patient.

Carcinoma de células escamosas de grandes proporções

The oral and oropharyngeal cancer is aggressive and, in Brazil, the incidence is considered one of the world’s tallest, the most common of head and neck. It affects males more intensively and 70% of cases are in adults over 50 years of age. It is located usually on the floor of the mouth and tongue. Therefore, the purpose of this study is to report a case of male patient, 78 years of age, leukoderma who sought hospital care. Reported frequent smoking and alcoholism. On physical examination headgear, there was the presence of lymph node fixed, painless 1.5 to 2 cm in diameter in the submandibular region. Physical examination intraoral ulcer was found at about 5 cm at its greatest extent, localized to the left oral floor region of the oropharynx, reddish, hardened edges, surface and bottom corrugated carton. The differential diagnosis suggested was traumatic ulcer, paracoccidioidomycosis and squamous cell carcinoma. The approach employed was obtained by incisional biopsy and the piece sent to histopathological analysis, confirming the case of squamous cell carcinoma. The treatment consisted in clarifying the patient about the disease and the need to search for an oncology center. It is concluded that the oral clinical examination is accurate in all major injuries to mouth, even if the chief complaint does not focus on this. In individuals at high risk examination should be systematic and individuals with suspicious lesions should be referred to specialist consultation.

Granuloma periférico de células gigantes: relato de caso

The peripheral giant cell granuloma (GPCG) is defined as a benign disorder of uncertain etiopathogenesis and proliferative reaction of the fibrous connective tissue or periosteum, which is characterized histologically by the presence of multinucleated giant cells. The purpose of this study is to report a case of GPCG in a 56-year-old white woman presenting a bleeding nodule on palpation, a red color with small whitish ulcerated areas, defined limits, resilient consistency, a pedicled base 2.0 cm in diameter, asymptomatic, involving the permanent lower left third molar, which presented mobility. Radiographically there was significant bone loss in this tooth region, whose initial diagnosis was pyogenic granuloma. The definitive diagnosis was obtained after excisional biopsy the microscopic examination of which identified the presence of multinucleated giant cells. The clinical postoperative follow-up revealed a favorable cicatricial repair of the operated area with no recurrence after 9 months of monitoring.

Granuloma Periférico de Células Gigantes: Relato de caso com acompanhamento de 2 anos

The peripheral giant cell granuloma (GPCG) is defined as a benign disorder of uncertain etiopathogenesis, and proliferative reaction of the fibrous connective tissue or the periosteum, which is characterized histologically by the presence of multinucleated giant cells. The purpose of this study is report a case of GPCG in a white women, with 56 years old, presenting nodule bleeding to the touch, red and white with small ulcerated areas, defined limits, resilient consistency, pedicled base with 2.0 cm diameter, asymptomatic, involving the permanent lower left third molar, that it was presented with mobility. Radiographically there was significant bone loss in this tooth region, whose initial diagnosis was pyogenic granuloma. The definitive diagnosis was obtained after excisional biopsy in which microscopic examination it was identified e presence of multinucleated giant cells. The clinical postoperative presented favorable cicatricial repairing of the operated area without recurrence after two years of monitoring.

Considerações atuais da sialolitíase de ducto de glândula submandibular

The sialolithiasis is characterized by the formation of calcified structure called sialolith within the salivary ductal system. Although its etiology is unknown, it is believed that is from the deposition of calcium salts around an accumulation of organic leftovers in the lumen of the duct or be resulted by chronic sialadenitis and partial obstruction. In this study, the authors describe a case of a male patient, 46 years old, brown, who presented the complaint “pain under the tongue.” The presence of a hardened nodule located in the left sublingual fold was observed through intra-oral exam. Current considerations about treatment, clinical and radiographic characteristics were addressed in this work.

Lymphoepithelial cyst in jugal mucosa

Mouth lymphoepithelial cyst is rare, with few cases reported in literature. The aim of this article is to describe a clinical case, focusing on clinical and diagnostic aspects, treatment and prognosis. The lesion was one year old and had developed as a fibrous nodule in the jugal mucosa of a 71-year-old leucoderma patient. Considering focal inflammatory fibrous hyperplasia, fibroma and mucocele as differential diagnosis, excisional biopsy was carried out. A cystic cavity limited by pseudostratified epithelium without projections into the conjunctive tissue, with lymphoid tissue within, was microscopically identified. Without postoperative adverse events, the one-year clinical followup confirmed the favorable prognosis of this kind of lesion.

Secondary aspergillus fumigatus infection associated with coloidal goiter in a Black-masked Lovebird (Agapornis personata)

Aspergillosis is caused by fungus of Aspergillus genus. Is a multifactorial secondary disease and occurs mainly to immunodeficiency. Goiter is the name to non-inflammatory and non-neoplasic thyroid growth which affecting the animal metabolism. In this report we describe a case of aspergillosis and colloidal goiter in a male Black-masked lovebird (Agapornis personata) diagnosed by post mortem exam. The bird was presented for examination due to severe respiratory signs. An initial palliative treatment was performed in order to relieve the symptoms. Despite this, the patient came to die without performing additional ancillary tests. On gross exam, a pulmonary nodule was observed from which we were able to isolate Aspergillus fumigatus on microbial culture. Histological assessment revealed pulmonary aspergilosis and colloid goiter. Based on histopathological and microbiological assessments we conclude that infection probably was secondary to colloid goiter.
