Efeito da coenzima Q10 nos danos oxidativos induzidos pela L-tiroxina no músculo sóleo de ratos

Introduction: skeletal muscles are dynamic tissue that can change their phenotypic characteristics providing a better functional adaptation to different stimuli. L-thyroxine is a hormone produced by the thyroid gland and has been used as an experimental model for stimulation of oxidative stress in skeletal muscle. Coenzyme Q10 (CoQ10) is a fat-soluble provitamin endogenously synthesized and found naturally in foods such red meat, fish, cereals, broccoli and spinach. It has antioxidant properties and potential in the treatment of degenerative and neuromuscular diseases. Objective: to evaluate the protective effect of CoQ10 in the soleus muscle of rats against the oxidative damage caused by L-thyroxine. Methods: the rats were divided in four groups of six animals each: Group 1 (control); Group 2 (coenzyme Q10); Group 3 (L-thyroxine), and Group 4 coenzyme Q10 and L-thyroxine). After euthanasia, blood was collected and serum activity of the enzymes creatine kinase (CK) and aspartate aminotransferase (AST) was analyzed. In the soleus muscle homogenates the factors related to oxidative stress were assessed. Results: CoQ10 protected the soleus muscle against the damage caused by L-thyroxine and favored the maintenance of the antioxidant enzymes glutathione reductase and glutathione peroxidase, the concentration of decreased and oxidized glutathione, and prevented lipid peroxidation. Conclusion: the results indicate that CoQ10 protects rat soleus muscle from oxidative damage caused by L-thyroxine.

Avaliação ultrassonográfica de crianças com hipotireoidismo congênito

To establish benchmarks and study some sonographic characteristics of the thyroid gland in a group of euthyroid children aged up to 5 years as compared with age-matched children with congenital hypothyroidism. Thirty-six children (17 female and 19 male) aged between 2 months and 5 years were divided into two groups - 23 euthyroid children and 13 children with congenital hypothyroidism - and were called to undergo ultrasonography. In the group of euthyroid children (n = 23), mean total volume of the thyroid gland was 1.12 mL (minimum, 0.39 mL; maximum, 2.72 mL); a homogeneous gland was found in 17 children (73.91%) and 6 children (26.08%) had a heterogeneous gland. In the group of children with congenital hypothyroidism (n = 13), mean total volume of the thyroid gland was 2.73 mL (minimum, 0.20 mL; maximum, 11.00 mL). As regards thyroid location, 3 patients (23.07%) had ectopic thyroid, and 10 (69.23%) had topic thyroid, and out of the latter, 5 had a homogeneous gland (50%) and 5, a heterogeneous gland (50%). In the group with congenital hypothyroidism, 6 (46.15%) children had etiological diagnosis of dyshormoniogenesis, 3 (23.07%), of ectopic thyroid, and 4 (30.76%), of thyroid hypoplasia. Thyroid ultrasonography is a noninvasive imaging method, widely available, easy to perform and for these reasons could, and should, be performed at any time, including at birth, with no preparation or treatment discontinuation, to aid in the early etiological definition of congenital hypothyroidism.

Diabetes mellitus: avaliação do conhecimento de cirurgiões-dentistas em municípios de três estados brasileiros

Introduction: Pathological changes in the bucal cavity associated with Diabetes mellitus (DM) may include gingivitis, periodontal disease, salivary gland dysfunction and xerostomia (dry mouth), susceptibility to bucal infections, burning mouth syndrome, and altered taste. Objective: This study assessed the technical and scientific knowledge of dentists working in primary care in the National Health System (SUS) on the DM. Material and method: The study was conducted in the municipalities of Birigui-SP, Maringá-PR and TrêsLagoas-MS, with the participation of 76 dentists working in the SUS primary care system.These professionals agreed to answer to a questionnaire developed for this study and the results of the questions were submitted to a quantitative analysis. Result: Showed that 94.7% were in contact with diabetic patients; 97.4% know what is DM; about other types of DM, 77.6% said they know, the most mentioned (by 55.9%) was the gestational DM. The DM2 was indicated as the most prevalent by 59.2%; the normal range of fasting blood glucose level was quoted correctly by 2.6% of the participants; obesity was reported by 98.7% of participants as a risk factor for DM; 96.0% stated correctly what are the main signs and symptoms related to Diabetes; periodontal disease was reported by 92.1% as an bucal manifestation in diabetic patients. Conclusion: The dentist needs to develop specific knowledge about DM, being able to identify normal levels of blood glucose and ready to identify and meet the bearer of DM.

Diagnóstico e tratamento de mucocele em odontopediatria: relato de caso

Mucocele is a retention phenomenon from minor salivary gland caused by the excretory ducts rupture. This phenomenon may be caused by local trauma and its location is usually more frequent in the lower lip. Clinically, they appear as nodular lesions and may be exophytic and pedunculated. Histologically, this lesion can be classified as mucus extravasation phenomenon and mucus retention cyst. The treatments described in the literature are total lesion excision, marsupialization, cryosurgery, laser or micromarsupialização. To report a case of mucocele by mucus extravasation developed after a local trauma. A 7 years old Male was attended in the Pediatric Dentistry Clinic, Araçatuba School of Dentistry, complaining about the appearance of lesion in the lower lip since 40 days approximately. During clinical oral examination, it was observed that the lesion was pedunculated, nodular, fibrous to palpation, around 2 cm in diameter, similar in color to the surrounding mucosa, smoothly in surface, non-ulcerated and asymptomatic. As treatment, it was chosen the total lesion excision. Histopathology test confirmed the clinical diagnosis of: mucocele. Since mucocele is a frequent lesions in the oral cavity, it is extremely important that the professionals can to recognize this lesion (its pathogenesis and clinical features), to achieve a definitive diagnosis and perform an appropriate treatment.

Transplante multivisceral em suínos: modelo de pesquisa e treinamento

Objective: To present a model for research and training in multivisceral transplantation in pigs. Methods: Eight Large White pigs (four donors and four recipients) were operated. The multivisceral transplant with stomach, duodenum, pancreas, liver and intestine was performed similarly to transplantation in humans with a few differences, described below. Anastomoses were performed as follows: end-to-end from the supra-hepatic vena cava of the graft to the recipient juxta diaphragmatic vena cava; end-to-end from the infra-hepatic vena cava of the graft to the inferior (suprarenal) vena cava of the recipient; and endto-side patch of the aorta of the graft to the infrarenal aorta of the recipient plus digestive reconstruction. Results: The performance of the multivisceral transplantion was possible in all four animals. Reperfusions of the multivisceral graft led to a severe ischemia-reperfusion syndrome, despite flushing of the graft. The animals presented with hypotension and the need for high doses of vasoactive drugs, and all of them were sacrificed after discontinuing these drugs. Conclusion: Some alternatives to minimize the ischemia-reperfusion syndrome, such as the use of another vasoactive drug, use of a third pig merely for blood transfusion, presence of an anesthesia team in the operating room, and reduction of the graft, will be the next steps to enable experimental studies.

Endovascular repair of a juxtarenal saccular aneurysm using the Multilayer Flow Modulator: report of the first case performed in a Public Hospital in Brazil

Endovascular aortic aneurysm repair (EVAR) involving renal and visceral arteries remains a great challenge. Several techniques have been developed over the time to treat juxtarenal, pararenal and thoracoabdominal aneurysms, highlighting the fenestrated and branched endografts, parallel prostheses as Chimney, Periscope and Sandwich Techniques and the use of flow modulation by multilayer stent. We report a case of saccular juxtarenal aortic aneurysm with high surgical risk for complex airway access due to a history of radical laryngectomy for laryngeal neoplasm. Due to chronic aorto-iliac obstructive disease, ostial stenosis of renal artery and limited diameter of the suprarenal aorta, we discarded options involving fenestrated/branched endografts and involving parallel prostheses techniques. We present this case as a therapeutic challenge and a successful treatment option in the short-term evaluation.
