A 2-year-old recently spayed female Rottweiler was referred as an emergency with cardiac tamponade and the presence of an anomalous retrograde flow in the pulmonary artery. Echocardiography and angiography demonstrated a left-to-right aortopulmonary fistula. Clinical history and data indicated a possible infectious aetiology. Antibiotics and heart failure medications were administered for 30 days before intervention. Initial attempt at insertion of an Amplatz occluder by means of a percutaneous catheterization technique was tried but a safe release of the device was judged to be not possible due to the angle and the fragile and irregular margins of the window...

Coronary-cameral fistulas (CCF) are anomalous connections between one or more coronary arteries and a cardiac chamber, most commonly the right ventricle or right atrium. The major indications for closure are: significant left to right shunt, myocardial ischaemia, prevention of endoarteritis or rupture. Nowadays, the first option for treatment is transcatheter closure. According to the morphology of the fistulas the most appropriate occluder device should be selected: coils (e.g., Gianturco coils, controlled-release coils, PFM coils), vascular plugs or a patent ductus arteriosus (PDA) device or muscular ventricular septal defect (VSD) device...

The treatment for oral cancer usually involves surgical excision followed by chemotherapy and/or radiotherapy. The combination of these therapies generally promotes a serious inflammation of the mucosa of the digestive tract, denominated mucositis, which compromises continuity of treatment. Photobiomodulation (PBM) therapy has been used successfully to reduce the oral mucositis, however there is still some controversy regarding the effects of this therapy on unintentionally irradiated tumor cells that may remain after cancer treatment...

INTRODUCTION: The association between periodontal disease (PD) and chronic obstructive pulmonary disease (COPD) has been widely studied, with aspiration of periodontal pathogens being one of the most accepted causal mechanisms for pulmonary exacerbation. Periodontal treatment (PT) was associated with a decrease in these exacerbations. Bronchiectasis is a pulmonary disease that has many similarities to COPD; however, there are no studies correlating this condition to PD thus far. This study will evaluate if PT reduces proinflammatory cytokines in serum and saliva, as well as halitosis and the amount of microorganisms associated with exacerbation of bronchiectasis in saliva, sputum and nasal lavage 3 months after PT...

Advanced two-dimensional echocardiographic techniques allow strain (S) analysis of regional function and thus can provide information on regional myocardial deformation. Feature-tracking echocardiography (FTE) is based on a mono-dimensional technology and may offer more detailed information about septal deformation because it can analyse the activity of left- and right-sided septal fibres separately. The present study aimed to quantify global and regional (free wall and septal) right ventricular (RV) longitudinal S and strain rate (SR)...
