Introduction The identification of a heart murmur early in life may be indicative of a significant congenital malformation of the heart. It is important to be able to differentiate potentially life-threatening lesions from benign processes. To do this, a basic understanding of these potentially complex lesions is necessary. When the diagnosis of a significant heart murmur seriously is considered, these infants must be referred to a pediatric cardiologist and pediatric cardiac surgeon for appro- priate diagnosis and corrective or palliative procedures. A relatively simple way to classify these potentially confusing lesions is according to categories based on the major presenting symptom: con- gestive heart failure or cyanosis (Table 14. Diagnosis of these lesions frequently can be made on the basis of the history and physical examination as well as with some basic noninterventional testing, 257 258 A. Cardiac catheterization in the diagnosis of these patients is required in fewer than 20% of all cases. Infants and children with congestive heart failure are symptomatic for either of two reasons: obstructing lesions or overcirculation of the lungs. Obstructive lesions leading to signs and symptoms of congestive heart failure involve the heart valves or the aorta. These include aortic stenosis, mitral stenosis, and various degrees of narrowing of the tho- racic aorta between the aortic valve and the level of the ductus arte- riosus. Initial presentation can range from a benign sounding heart murmur to life-threatening congestive heart failure. The symptoms caused by the obstructive lesion are attributed to blood backing up into the pulmonary circulation, causing pulmonary edema or congestion. Congestive heart failure also can be caused by left to right shunting of arterial blood, leading to overcirculation of the lungs. Abnormal communication can exist at the level of the atria (atrial septal defect), ventricles (ventricular septal defect), or in an extracardiac location (aortopulmonary window or patent ductus arteriosus signs). The most common symptoms that occur in this setting include recurrent upper respiratory infection, tachypnea, tachycardia, and failure to thrive. Oxygenated blood flows from the left side to the right side of the circulation because of the lower resistance and pressures in the right side of the heart. Excessive flow of blood through the pulmonary vasculature results in congestive heart failure and pulmonary hypertension. Pulmonary vascular resistance gradually increases due to this overcirculation from a complex interaction of factors. Even before Eisenmenger’s syndrome occurs, a high fixed resistance may preclude surgical correction. The infant in the case presented above is consistent with an infant who has either an obstructive lesion or a shunting lesion. The presence of congestive heart failure and the absence of cyanosis places the infant in this category. Cyanosis The cyanosis related to cyanotic congenital heart disease is due to the significant mixing of oxygenated and nonoxygenated blood within the heart and the output of this blood to the systemic circulation. For this to occur, either an intracardiac defect with pulmonary outflow obstruction (forcing blood to shunt right to left) or a complex congen- ital anomaly must exist. When the absolute level of desaturated blood in the systemic circulation exceeds 5g/mL, cyanosis appears. In the first, septal defects similar to those that occur in left to right shunting are present, but these are asso- ciated with some form of pulmonary outflow obstruction (subvalvu- lar, supravalvular, or atresia of the pulmonary arteries). The classic lesion is known as tetralogy of Fallot (ventricular septal defect, overriding aorta, pul- monary arterial obstruction, and right ventricular hypertrophy). The other lesions causing cyanosis, in which markedly abnormal anatomy exists, such as transposition of the great vessels and total anomalous pulmonary venous return, are referred to as “complex lesions. The parent usually is most observant of abnormalities in the child’s behavior, especially if there is an older sibling with whom to compare the child’s behavior, as in the case pre- sented above. Family history is relevant, as there may be as much as a threefold increase in the incidence of congenital disease when a prior sibling has been born with a congenital defect. Signs and symptoms of congestive heart failure should be sought from the parent, espe- cially recurrent respiratory infections or difficulties feeding (shortness of breath, sweating). Cyanosis may appear early in neonates born with transposition of the great vessels or some other complex lesion. Perfu- sion of the pulmonary circulation may have been dependent on a patent ductus arteriosus communicating between the descending tho- racic aorta and the pulmonary artery. As the ductus begins to close in the first hours and days of life, decreased pulmonary blood flow and cyanosis, either from hypoxia or new right to left flow, occurs. Heart Murmurs: Congenital Heart Disease 261 Prostaglandin may be necessary to maintain this fetal circulation (patent ductus) until diagnostic studies can be completed. Other infants do not develop signs of cyanosis until they are a few months of age. Signs of cyanosis related to tetralogy of Fallot may not appear until several months of life as pulmonary outflow obstruction (and right-to-left shunting) increases. The physical examination is directed to a systematic evaluation of the infant or child. Findings consistent with congestive heart failure or chronic hypoxemia are sought. With obstructive lesions, this usually is consistent with the murmurs of aortic or mitral stenosis. Ventricular septal defects usually have a continuous “machinery-type” murmur over the ante- rior chest. The murmur of an atrial septal defect is related to increased blood flow across the pulmonic valve and not to the flow across the atrial septum. This murmur is thus loudest over the pul- monary outflow tract to the left side of the sternum. A systolic murmur heard loudest in the back is suggestive of coarctation of the aorta, especially if lower extremity pulses are decreased. Hepatomegaly may be a consistent finding in the presence of congestive heart failure. Examination of the periphery is crucial in looking for signs of cyanosis, clubbing, or microemboli, which may be present in right-to-left shunting. Diagnostic Studies Routine chest x-ray may be diagnostic, especially to a well-trained pediatric radiologist. Over- or undercirculation of the lungs may be present along with cardiomegaly and other deformities of the base of the heart.

It is also of advantage in other inflammatory diseases order cialis sublingual 20mg, and in fevers with similar symptoms cialis sublingual 20 mg cheap. In such cases patients have lemon juice or lemonade to the extent they may have a desire for it cheap cialis sublingual 20 mg visa. It also exerts a marked influence when locally applied, in hypertrophy of the tonsils, and elongated uvula. Coffee is a stimulant to the cerebral nervous system, and may be employed in many cases where there is atony, with disordered function. Were it not for the general use of coffee as a beverage, it would prove a valuable remedy; but when persons are habituated to its use, it exerts but little influence. It is difficult to procure a reliable preparation of Colchicum, and we have been obliged to use the English wine of Colchicum. Colchicum has long been used as a remedy for rheumatism and gout; and, though probably the best of the old materia medica, it failed of giving its best results because used in poisonous doses. In acute and chronic rheumatism it should be employed in small doses, following or alternated with the sedatives. We only obtain its anti-rheumatic influence when the pulse and temperature are reduced to nearly a normal standard. It is also beneficial in some cases of intestinal disturbance, especially when there is gaseous accumulation. Thus in colic from intestinal irritation, it may be employed in the proportion of gtt. It exerts an influence upon the skin, and may occasionally be employed with advantage in chronic disease of the surface. Kelley writes me in reference to the specific indications for Colchicum: - “The pain for Colchicum, so far as my experience goes, is, sharp- shooting, tearing or dull aching, extending from the back to hip, and down the limb, without fever. It is not the kind of pain so much as its position; hence it is of value in certain forms of chronic or sub-acute sciatica. Whenever I have used it in such cases for pain in that region, its use has been attended with good results. Colocynth has been employed as a cathartic, but for this purpose it is harsh and uncertain, and may well be dispensed with. It will also prove beneficial in some cases of diarrhœa attended with tormina and tenesmus. I am satisfied that a thorough investigation of the remedy in small doses, will develop other important uses. As there are a great many imperfect preparations in the market, I would advise that it be procured from one of our own houses in this city. Collinsonia is a specific in ministers’ sore throat; administered in the proportion of: ℞ Tincture of Collinsonia, simple syrup, āā. It proves beneficial in other cases of chronic laryngitis, in chronic bronchitis, and phthisis, allaying irritation, and checking cough. It also exerts a favorable influence upon the digestive processes, improving the appetite, facilitating digestion and acting as a general tonic. It passes off through the kidneys, and exerts a tonic influence upon the entire extent of the urinary tract. I have thought that its influence was specially exerted upon and through the pneumogastric, relieving irritation of, and giving strength to parts supplied from this source. Collinsonia is a specific in the early states of hemorrhoids, and will sometimes effect a cure in the advanced stages of the disease In this case it is employed in small doses: ℞ Tincture of Collinsonia, gtt. I have given the therapeutics of Collinsonia thus briefly, that the points named might make the greater impression upon the reader. I regard it as one of the most direct and valuable agents of the materia medica, and one that will give satisfaction to whoever employs it. It may prove useful in the early stages of tuberculosis, by enabling the person to take the exercise so much needed to burn the imperfect materials in the blood. The dose of the crude leaves is from five to ten grains, but it is better employed in infusion. A tincture is prepared from it in the usual way, of which the dose is from the fraction of a drop to ten drops. In the colliquative perspiration of phthisis, it is thought to give better results than the remedies ordinarily employed. It may be employed in diarrhœa with colic, and in dysentery when the febrile symptoms are relieved. It may be used to lessen the frequency of the pulse, when there is an impaired capillary circulation, as shown by ecchymosis, or the slow return of blood when it is effaced by the finger. The tincture of the root has had some reputation in the treatment of rheumatism and dropsy, and to improve the digestive functions. The dose will vary from a dilution to as much as a half drachm There is no doubt that this remedy exerts a special action upon the circulation, especially the veins. It relieves congestion of the liver, spleen, and intestine, promotes a better circulation in the portal system, and relieves and sometimes cures hemorrhoids. As a local application it has been used in bruises and ecchymosis, in acute and chronic conjunctivitis, in hemorrhoids, and to varicose ulcers. It may be given in cardialgia, in hepatic colic, in diarrhœa with tenesmus, and in dysentery if the patient is free from fever, it is also employed in chronic diseases of the skin, especially those which are pustular, and when the surface burns and itches on getting warm in bed and from active exercise. Administered in substance in doses of five to twenty grains, it exerts a direct influence upon the bladder and urethra, and will sometimes cure an old gonorrhœa or gleet when other remedies fail. It has also been used in the scalding of urine in women, and burning and irritation of the vulva. It will be found useful in some cases of cystitis, the more acute symptoms having passed away. In the small dose it may be used in debility with irritation of the reproductive apparatus, prostatorrhœa, uneasiness and formication of scrotum and anus, and diseases associated with reproductive weakness. This tincture may be given in irritation of the urinary passages, sharp pains in the loins, and in rheumatic pains of the shoulders. Even yet I prefer to give Copper in this form, rather than as a medicine, but probably this is owing to prejudice. The cases where I have found it especially beneficial, were those in which with anæmia there was not very great loss of flesh. The surface would be pallid, or sometimes tawny, the skin waxy, parts usually colored with blood pale, with sometimes a slight greenish tinge. It makes no difference what the disease is, if these symptoms should present I would think of Copper as a remedy. Rademacher employed Copper in the treatment of acute diseases, and claimed that there were seasons when the endemic constitution of disease demanded it.

Very long-chain fatty acids (>20 carbons) enter peroxisomes via an unknown mechanism for oxidation order cialis sublingual american express. Fatty Acid Entry Into Mitochondria Long-chain fatty acids must be activated and transported into the mitochondria cialis sublingual 20 mg low price. Fatty acyl- CoA synthetase cheapest generic cialis sublingual uk, on the outer mitochondrial membrane, activates the fatty acids by attaching CoA. The fatty acyl portion is then transferred onto carnitine by carnitine acyltransferase-1 for transport into the mitochondria. The sequence of events is shown in Figure 1-16-2 and includes In a Nutshell the following steps: Carnitine Acyltransferases • Fatty acyl synthetase activates the fatty acid (outer mitochondrial membrane). The Carnitine acyltransferase-1 is inhibited by malonyl-CoA from fatty acid synthesis and thereby carnitine transport system is prevents newly synthesized fatty acids from entering the mitochondria. Insulin indirectly inhib- most important for allowing its ~-oxidation by activating acetyl-CoA carboxylase (fatty acid synthesis) and increasing the long-chain fatty acids to enter malonyl-CoA concentration in the cytoplasm. The pathway is a repetition of four ~-oxidation of palrnitate (16:0) steps and is shown in Figure 1-16-2. In a fasting state, the liver produces more acetyl-CoA from ~-oxidation than is used in the citric I..... Non-ketotic hypoglycemia should be strongly associated with a block in hepatic p-oxidation. Decreased acetyl- CoA lowers pyruvate carboxylase activity and also limits ketogenesis. It is characterized by a sudden A 6-year-old suffered gastroenteritis for 3 days that culminated in a brief onset of vomiting 2-6 hours generalized seizure, which left him semicomatose. After a period Administering intravenous glucose improved his condition within 10 minutes. Hallmarks of this disease include: • Muscle aches; mild to severe weakness • Rhabdomyolysis, myoglobinuria, red urine Episode provoked by prolonged exercise especially after fasting, cold, or associated stress • Symptoms may be exacerbated by high-fat, low-carbohydrate diet Muscle biopsy shows elevated muscle triglyceride detected as lipid droplets in cyto- plasm • Primary treatment: cease muscle activity and give glucose A somewhat similar syndrome can be produced by muscle carnitine deficiency secondary to a defect in the transport system for carnitine in muscle. Propionic Acid Pathway Fatty acids with an odd number of carbon atoms are oxidized by ~-oxidation identically to even-carbon fatty acids. The difference results only from the final cycle, in which even-carbon fatty acids yield two acetyl-CoA (from the 4-carbon fragment remaining) but odd-carbon fatty acids yield one acetyl-CoA and one propionyl-CoA (from the 5-carbon fragment remaining). Propionyl-CoA is converted to succinyl-CoA, a citric acid cycle intermediate, in the two-step propionic acid pathway. Because this extra succinyl-CoA can form malate and enter the cyto- plasm and gluconeogenesis, odd-carbon fatty acids represent an exception to the rule that fatty acids cannot be converted to glucose in humans. The propionic acid pathway is shown in Figure 1-16-3 and includes two important enzymes, both in the mitochondria: • Propionyl-CoA carboxylase requires biotin. In a patient with megaloblastic anemia, it is important to determine the underlying cause because B[2 deficiency, if not corrected, produces a peripheral neuropathy owing to aberrant fatty acid incorporation into the myelin sheets associated with inadequate methylmalonyl-CoA mutase activity. Cardiac and skeletal muscles and renal cortex metabolize acetoacetate and 3-hydroxybutyrate to acetyl-CoA. Normally during a fast, muscle metabolizes ketones rapidly as the liver releases them, preventing their accumulation in blood. After a week of ing, ketones reach a concentration in blood high enough for the brain to begin metabolizing them. Ketogenesis (Liver) and Ketogenolysis (Extrahepatic) Ketogenesis Ketogenesis occurs in mitochondria of hepatocytes when excess acetyl-CoA accumulates in the fasting state. Acetone is a minor side product formed nonenzymatically but is not used as a fuel in tissues. It does, however, impart a strong odor (sweet or fruity) to the breath, which is almost diagnostic for ketoacidosis. Ketogenolysis in Brain Figure 1-16-5 shows the major pathways producing fuel for the brain. Note the important times at which the brain switches from: • Glucose derived from liver glycogenolysis to glucose derived from gluconeogenesis (~12 hours) Glucose derived from gluconeogenesis to ketones derived from fatty acids (-1 week) In the brain, when ketones are metabolized to acetyl-CoA, pyruvate dehydrogenase is inhibited. This important switch spares body protein (which otherwise would be catabolized to form glucose by gluconeogenesis in the liver) by allowing the brain to indirectly metabolize fatty acids as ketone bodies. An infection or trauma (causing an increase in cortisol and epinephrine) may precipitate an episode of keto- acidosis. The basis for this observation is not completely understood, although type 2 disease has a much slower, insidious onset, and insulin resistance in the periphery is usually not complete. Chronic hypoglycemia, which is often present in chronic alcoholism, favors fat release from adipose. Ketone production increases in the liver, but utilization in muscle may be slower than normal because alcohol is converted to acetate in the liver, diffuses into the blood, and oxidized by muscle as an alternative source of acetyl-CoA. In pathologic conditions, such as diabetes and alcoholism, ketoacidosis may develop with life-threatening consequences. In diabetic and alcoholic ketoacidosis, the ratio between acetoacetate and ~-hydroxybutyrate shifts and ~-hydroxybutyrate predominates. The urinary nitroprusside test detects only aceto- acetate and can dramatically underestimate the extent of ketoacidosis and its resolution during treatment. Home monitors of both blood glucose and ~-hydroxybutyrate are available for diabetic patients. Although sphingolipids contain no glycerol, they are similar in structure to the glycerophos- pholipids in that they have a hydrophilic region and two fatty acid-derived hydrophobic tails. The various classes of sphingolipids shown in Figure 1-16-7 differ primarily in the nature of the hydrophilic region. Lysosomes contain many enzymes, each of which removes specific groups from individual sphingolipids. Genetic deficiencies of many of these enzymes are known, and the diseases share some of the characteristics of I-cell disease discussed in Chapter 4. The attending physician noted massive hepatomegaly and splenomegaly, mental retardation, marked pallor, and hematologic complications. White cells were taken to assay for glucocerebrosidase, and the activity of the enzyme was found to be markedly below normal. Except for the brain, glucocerebroside arises mainly from the breakdown of old red and white blood cells. In the brain, glucocerebroside arises from the turnover of gangliosides during brain development and formation of the myelin sheath. Without the proper degradation of glucocerebroside due to a lack of glucocerebrosidase, it accumulates in cells and tissues responsible for its turnover. The easy bruising is due to a low blood platelet count, and the lethargy is due to the anemia. Enzyme replacement therapy results in the reduction of hepatosplenomegaly, skel- etal abnormalities, and other Gaucher-associated problems. The major drawback of therapy using intravenously administered recombinant glucocerebrosidase is its prohibitive cost (several hundred thousand dollars per year). As part of a study to quantify contributors of stress to hyperglycemia and ketosis in dia- betes, normal hepatocytes and adipocytes in tissue culture were treated with cortisol and analyzed by Northern blotting using a gene-specific probe. A child is diagnosed with a congenital deficiency of medium-chain acyl-CoA dehydroge- nase activity.
