Since the cardiomyopathy is considered irreversible 20 mg vasodilan with amex, cardiac transplantation is the only viable option to improve function vasodilan 20mg discount. The prognosis after cardiac transplantation tends to be favorable since this form of chronic Chagas’ disease is usually limited to the heart buy discount vasodilan 20 mg line. Many forms of acute viral myocarditis or stress cardiomyopathy are expected to improve with time. The most common cause is sequelae of rheumatic carditis, and symptoms of stenosis usually develop two decades after the onset of carditis. Due to elevated left atrial pressure and concomitant left atrial dilation, these patients are at high risk for developing atrial ﬁbrillation, pulmonary hypertension, and right-ventricular failure. Right-ventricular outﬂow tract tachycardia is unrelated to val- vular pathology and is common in the young and women. Additionally, multiple systemic disorders are associated with sinus bradycar- dia, for instance, hypothyroidism, advanced liver disease, hypoxemia, hypercapnia, acide- mia, and acute hypertension. Finally, several infectious diseases are classically associated with sinus bradycardia, notably typhoid fever and brucellosis. Pulmo- nary hypertension may develop in individuals with a signiﬁcant left-to-right shunt such as an undiagnosed atrial septal defect. Pulmonary hypertension is the result of increased blood ﬂow across the pulmonary vascular bed, leading to obliteration of the vascular bed. With the development of signiﬁcant pulmonary hypertension, Eisenmenger syndrome may develop. This occurs when a right-to-left shunt develops as a result of pulmonary hypertension. Erythrocytosis due to chronic hypoxemia is a common feature of cyanotic congenital heart disease with a hematocrit of up to 65–70% commonly seen. However, symptoms of hyperviscosity rarely develop, and phlebotomy is not frequently required. Stroke is greatest in children <4 years of age but is not in- creased in adults unless there is inappropriate use of anticoagulants, concomitant atrial ﬁbrillation, or infective endocarditis. As a result, there is slowing of the upstroke of the action potential as well as reduced duration of repolarization. In a patient with elevated left atrial pressures, the mitral valve opens quickly after closure of the aortic valve (A2) due to the relatively low pressure gradient across the mitral valve in early diastole. If the left atrial pressure were lower, it would take longer for the pressure gradient across the mitral valve to cause mitral valve opening. A short interval between A2 and the opening snap in- dicates very elevated left atrial pressures. Atrial ﬁbrillation, pulmonary vascular conges- tion, pulmonary hypertension, and right-ventricular failure (elevated jugular pressure, pulsatile liver, peripheral edema) are all potential sequelae of severe mitral stenosis. The abrupt onset of severe hyperten- sion or the onset of any hypertension before the age of 35 or after age 55 should prompt evaluation for renovascular hypertension. In addition, patients should be evaluated for secondary causes if previously well-controlled blood pressure suddenly becomes increas- ingly difﬁcult to control as this may indicate the development of renovascular disease. Any symptoms or physical ﬁndings of concern should be investigated further as well. In the scenarios presented in Question 27, (B) should signal concern for adult-onset poly- cystic kidney disease and (E) describes a woman with possible Cushing’s disease. Other causes of secondary hypertension include pheochromocytoma, primary hyperaldoster- onism, medication-induced, and vasculitis. Pa- tients with the tachycardia-bradycardia variant of sick sinus syndrome are at risk for thromboembolism. Those at greatest risk include age >65 years, prior history of stroke, valvular heart disease, left ventricular dysfunction, or atrial enlargement. There is no reason to discontinue dypyridamole at this time as she is complaining of no side effects, and the absence of angina argues against the need for cardiac catheterization. The most common causes of cardiac tamponade are neoplasm, renal failure, and idiopathic acute pericarditis. The amount of ﬂuid required to cause cardiac tamponade varies widely, depending upon the acuity with which the ef- fusion develops. Rapid accumulation of pericardial ﬂuid will result in tamponade with as little as 200 mL of ﬂuid, whereas a slow accumulation of pericardial ﬂuid may result in a pericardial effusion of ≥2000 mL. Cardiac tamponade can be rapidly fatal if not recog- nized and treated quickly with pericardiocentesis. Clinical features of pericardial tam- ponade are hypotension, mufﬂed heart sounds, and jugular venous distention, with a rapid x descent but without a y descent. In more slowly accumulating effusions, symptoms may be those of heart failure, with dyspnea and orthopnea common. Normally, blood pressure falls during inspiration, due to an increase in blood ﬂow into the right ventricle with displacement of the interventricular septum to the left, decreasing left-ventricular ﬁlling and cardiac output. This fall in blood pressure results in a fall in systolic blood pressure of ≤10 mmHg in normal individuals but is exag- gerated in cardiac tamponade. Echocardiogram is frequently diagnostic, showing a large pericardial effusion with col- lapse of the right ventricle during diastole. A right heart catheterization demonstrates equalization of pressures in all chambers of the heart. This is exempliﬁed in option C where the right-atrial pressure, right-ventricular diastolic pressure, pulmonary artery di- astolic pressure, and pulmonary capillary wedge pressure are equal. Option B would be seen in congestive heart failure, and option D is seen in pulmonary arterial hypertension. These changes are typical of emphysema when the thorax is hyperinﬂated with air and the ﬂattened diaphragm pulls the heart inferiorly and vertically. Patients with hypertrophic cardiomyopathy will have left ventricular hypertrophy and widespread deep, broad Q waves. Symptoms are due to conduction via an accessory pathway and include tachypalpitations, light headedness, syncope, cardiopulmonary collapse, and sudden car- diac death. Life-threatening presentations are usually due the development of atrial ﬁbril- lation or atrial ﬂutter with 1:1 conduction, which can both precipitate ventricular ﬁbrillation. Carvallo’s sign describes the increase in intensity of a tricuspid regurgitation murmur with inspiration. This occurs due to the increase in venous return during inspiration with falling pleural pressure. The Gallavardin effect occurs when the murmur of aortic stenosis is transmitted to the apex V. The Austin Flint murmur is a late diastolic murmur heard at the apex in aortic regurgita- tion. Atrial septal defects cause a mid-systolic murmur at the mid to upper left sternal border, with ﬁxed splitting of S2. The ventricular rate in this situation is quite rapid, and cardiovascular collapse or ventricular ﬁbrillation may result. The usual treatment is direct-current cardioversion, though quinidine may slow conduction through the bypass tract. Verapamil and propranolol have little effect on the bypass tract and may further depress ventricular function, which already is compromised by the rapid rate.

Dental management of diabetes The well-controlled diabetic child with no serious complications can have any dental treatment but should receive preventive care as a priority purchase genuine vasodilan on-line. Uncontrolled diabetes can result in varied problems discount vasodilan 20 mg free shipping, which mainly relate to fluid imbalance purchase generic vasodilan online, an altered response to infection, possible increased glucose concentrations in saliva, and microvascular changes. There may be decreased salivary flow, and an increased incidence of dental caries has been reported in uncontrolled young diabetics. There is also well- documented evidence of increased periodontal problems and susceptibility to infections, particularly with Candida sp. Dental appointments should be arranged at times when the blood sugar levels are well controlled; usually a good time is in the morning immediately following their insulin injection and a normal breakfast. General anaesthetics are a problem because of the pre-anaesthetic fasting that is required, and so these are normally carried out on an in-patient basis to enable the insulin and carbohydrate balance to be stabilized intravenously. However, problems in the dental management of patients with steroid insufficiency are more likely to occur in children who are being prescribed steroid therapy for other medical conditions; for example, in the suppression of inflammatory and allergic disorders, acute leukaemia, and to prevent acute transplant rejection. In children, the risks of taking corticosteroids are greater than in adults and they should only be used when specifically indicated, in minimal dosage, and for the shortest possible time. If a child has adrenal insufficiency and/or is receiving steroid therapy, then any infection or stress may precipitate an adrenal crisis. For routine restorative treatment no additional steroid supplementation is usually necessary. However, if extractions under local anaesthesia or more extensive procedures are planned and/or if the patient is particularly apprehensive, then the oral steroid dosage should be increased. Dental management should present no problems if the thyrotoxic patient is medically well controlled; however, liaison with the physicians is important. Left untreated, sufferers would die of infections but fortunately the majority respond to treatment using corticosteroids, usually prednisolone. The kidney undergoes a complex developmental and migratory process leading to a high frequency of congenital anomalies, such as polycystic disease and unilocular cysts. Acute pyelonephritis is more common when there is a congenital abnormality present and so, even though it is simply treated with antibiotics, children often undergo further medical investigations to rule out congenital abnormality. Therefore, children with renal problems are likely to be, or have been, under specialist medical care. From a dental viewpoint, children with reduced renal function, or more importantly, progressive renal failure need extra consideration when prescribing drugs. Child cancer patients largely reflect the child population in general and as such, represent a cross-section of the population. Cancer causes more childhood deaths between the ages of 1 and 15 years than any other disease, but is still considerably behind trauma as the most common reason for mortality. The incidence of malignant tumours in children under 15 years of age in developed countries is estimated to be in the region of 1 in 10,000 children per year but the mortality rate is high, at between 30% and 40%. Although leukaemia is the most common form of childhood cancer, tumours of the central nervous system and neural crest cells and lymphomas also form a significant proportion (Table 16. Prognosis varies with the type of tumour, the stage at which it was diagnosed, and upon the adequacy of treatment. Major advances have been made in the treatment of childhood malignancy in the last few decades, largely as a result of advances in chemotherapy and bone- marrow transplantation. Dental management of children with cancer The children may have untreated caries and, since many are under 5 years of age, and may not have had a previous dental examination. The immediate problems include mucositis (oral ulceration) and exacerbations of common oral diseases that may become life threatening and are usually managed by paediatric dentistry specialists in liaison with their medical colleagues. Child cancer survivors later present with long-term problems relating to: - growth; puberty, and reproduction; cardiac; thyroid; cognitive deficit; and social function. Oral and dental development can also be impeded and specialist advice might again be required. Key Points • Children with cancer need the combined care of primary and specialist dental services; • There are immediate and long-term effects of cancer treatment; • Disease prevention is vital. Bone marrow transplants are the treatment of choice for children with aplastic anaemia, those who fail conventional therapy for leukaemia, and for some immune deficiency disorders. Although children with end-stage renal disease can be kept alive by haemodialysis, their quality of life is considerably improved by kidney transplantation. Children who require organ transplantation are considered to be at a high caries risk and so prevention is important. Whenever possible, active dental disease should be treated before the transplant procedure and any teeth with doubtful prognoses extracted. This may present difficulties as many pretransplant patients can be seriously ill and have various associated medical problems. Children undergoing bone marrow transplantation are prone to infection, bleeding, and delayed healing due to leucopenia and thrombocytopenia. However, the majority of children awaiting liver transplantation due to biliary atresia are of a very young age and have not experienced dental caries, though their teeth may have intrinsic green staining due to biliverdin deposition in the developing dental tissues. This is a time when intensive oral hygiene instruction and preventive advice and therapy are of paramount importance in helping to minimize later potential oral problems. Prophylactic antibiotics will probably be required in patients with cardiac problems and depressed white blood cell counts. Any significant alterations in bleeding times and/or coagulation status must be checked. There are also certain drugs that should be avoided inpatients with end-stage liver or kidney disease. Azathioprine results in leucopenia, thrombocytopenia, and anaemia; hence, children in this immediate post-transplant phase may be even more prone to infections and haemorrhage than before. Cyclosporin (Neoral) and Tacrolimus are largely replacing azathioprine but these may cause severe kidney and liver changes leading to hypertension and bleeding problems. Full supportive dental care is required and children complain of nausea and may develop severe oral ulceration. Routine oral hygiene procedures can become difficult but the use of chlorhexidine as a mouthwash, spray, or on a disposable sponge, together with local anaesthetic preparations is helpful. Steroid therapy is discontinued in children with liver transplants after 3 months but may be continued for longer periods than this in those with other organ transplants. Antifungal prophylaxis is usually given in the first few months after transplantation to prevent oral candidal infections. Dental problems, apart from oral ulceration and those associated with immunosuppression and bleeding tendencies, include delayed eruption and exfoliation of primary teeth and ectopic eruption of permanent teeth. These are related to the gingival overgrowth associated with cyclosporin and nifedipine medication (Fig. Key Points Transplant immunosuppression: • leucopenia; • thrombocytopenia; • gingival enlargement.
