Still the reports from the South seemed well authenticated buy 50 mg fertomid amex pregnancy 9 weeks 2 days, that fertomid 50 mg mastercard menstruation hormones, at least in some cases buy generic fertomid 50 mg online menopause show, it was abortive generic fertomid 50mg otc menstrual irregularities, and was a very certain emmenagogue, and a stimulant diuretic. It is only another example of a fact I have insisted on, that many plants possessing medicinal properties when fresh, lose them when gathered at the wrong season and kept in stock. It also exerts a direct influence upon the urinary apparatus, increasing secretion and acting as a stimulant to the entire urinary tract. The indications for its use are a sense of fullness in the head, dizziness, flushed face, tensive pain as if the head would burst, partial loss of consciousness, or difficulty in drawing conclusions from impressions; throbbing in the whole body or in a particular part, as if the arteries were distended with blood, is deemed a good indication for glonoine. Locke for making a decoction are as follows: Put eight pints of water and eight ounces of prepared bark into a kettle and boil until the liquid is reduced to about four pints, then strain through muslin; press well. Add the contents of the strainer again to the same amount of water (eight pints), and boil until reduced to four pints, and strain as before. The indications for its use are - a feeble circulation of blood, pallid, transparent skin, pale tongue, impairment of the sexual function (irritation without power), irregular and painful menstruation, leucorrhœa. It may be employed in jaundice, dropsy, engorgement of spleen, fullness and oppression of the brain, and some other diseases where there is an obstructed circulation. Glycerine may be used in the prescription to hold the remedy in solution with water. I have employed it with good results in asthma, bronchorrhœa, dilated bronchia, old ulcers, and chronic diseases of the skin, with enfeebled circulation. I have employed it with marked benefit in the treatment of old and indolent ulcers. As we have an abundance of astringent remedies for diarrhœa, it is hardly worth while to import one, so that this may be tried in small dose for other effects. The Guarana of the drug market is the ground seed of the Paullinia Sorbilis, a native of Brazil. It is a stimulant to the cerebro-spinal centers, and its principal use now is to relieve headache. If the face is pallid, the eyes dull, the face expressionless, it may be used with advantage. It may be given in those severe headaches that recur with the menstrual period, the symptoms being as above, with a prospect of relieving the disease of the reproductive function, as well as the headache. It is indicated by vertigo, dizziness, variable appetite, cough, and may prove valuable in the early stages of phthisis. The tincture thus prepared may be occasionally used with advantage in the latter stages of acute, and in chronic rheumatism. It may also be associated with the vegetable alteratives in the treatment of some chronic diseases, where stimulation of the skin is required. Occasionally it will prove useful in functional diseases of the uterine organs, especially in amenorrhœa. An East Indian nut which has been employed in doses of one to ten grains in the treatment of agues, and as a prophylactic against malarial fevers. In doses of from one twenty-fifth of a grain to one grain, it is a remedy in some eruptive diseases, in enlargement of the spleen, hepatic pain, and œdematous swelling; it has also been employed in syphilis. For experiment, a tincture may be made of the bark, beans, or pulp of the seed-pod; the last being regarded as the most active. Herring concluded from his experiments that it might be given with benefit in cases of “cough accompanied or followed by tonsilitis; in erysipelas of the face; in scarlet fever; in so-called hives; in typhoid fever: in remittent or intermittent epidemic fever, with a typhoid character, etc. The ordinary fluid extract may be used as a topical application, as a gargle for the throat, and for the general purposes of an astringent. Where the Witch-Hazel can be readily obtained, I would advise that the leaves be gathered in June or July, and if no apparatus for distilling is at hand, that they be packed in a percolator, and a tincture prepared with a very weak spirit, say 30 per cent. The Hamamelis has a specific action upon the venous system, giving strength to it, and facilitating the passage of venous blood. It may, therefore, be employed with advantage in any case where a part is enfeebled, and there is a sluggish circulation. Thus we use it in cases of catarrh and ozæna; chronic pharyngitis, disease of the tonsils, pillars of the fauces, vellum and uvula, and in chronic laryngitis. The indications for its employment are, thickening of mucous membranes, with enfeebled circulation, and increased secretion, either mucous or muco-purulent. It is especially a valuable remedy in the treatment of hemorrhoids, sometimes effecting a cure in old and very stubborn cases without the use of other remedies. Usually, however, I use the solution of the persulphate of iron as a local application. It is also a very useful remedy in the treatment of diseases of the uterus and vagina. Given, a case with the conditions named, thickening, with relaxation, enfeebled circulation, and increased mucous, or muco-purulent secretion, and its action is very positive. We employ it also in the treatment of various lesions of the lower extremities, both as a local application and an internal remedy, and many times with excellent results. It is an excellent dressing for erysipelas, and for burns, giving that slight stimulation that seems to be required in these cases. I need not name other cases, as the indications for its use first given, will suggest its application. I regard it as one of the most valuable stimulant diaphoretics; very kindly received by the stomach, and quite certain in its action. It is an admirable remedy for amenorrhœa from cold; the safest and most certain we have, I think. It may be given in doses of a teaspoonful every hour or two hours, or two or three times in the evening, with the hot foot bath. Prepare your own tincture in this way: In July, gather a sufficient quantity of the herb, stem it, and at once pack the leaves in a percolator. Let it stand twenty-four hours, and then draw off, putting on water until the tincture measures Oj. It may have other properties, and it would be well to give it a thorough investigation. It has had a reputation as an antidote to the bite of poisonous snakes, and probably possesses some power in this direction. It exerts the general influence of a tonic, and a special tonic action upon the urinary and uterine organs. It is possible that if we can obtain a reliable preparation, it will be found superior to other remedies for these purposes. One of the special indications for its use is in the mental depression and irritability that attends many of these affections. I am of the impression that, in many cases, the relief of this cerebral disturbance is its most important action. The Hepatica exerts a slightly stimulant and tonic influence upon the stomach and small intestines, relieving irritation and promoting functional activity. Culpepper wrote, “It is a singularly good herb for all diseases of the liver, both to cool and cleanse it, and is serviceable in yellow jaundice. It is a singular remedy to stay the spreading of tetters, ringworms, and other fretting and running sores. Probably its best action is upon the bronchial mucous membrane, when enfeebled from inflammation or irritation, attended with profuse secretion. It has been employed as an antispasmodic, and we would judge that it was a spinal stimulant.

Echocardiogram The easiest and currently most accurate noninvasive test used in evaluating valvular heart disease is the echocardiogram, more specif- ically the transesophageal echocardiogram. These studies permit a simple screening for the presence and severity of a valvular lesion. At the same time, the presence of chamber enlargement or dysfunction can be determined. A simple method thus exists to permit the ongoing eval- uation of patients not yet deemed candidates for surgery. The presence or absence of calcification that might increase the complexity of surgery can be identified, and information can be provided on the suitability of a patient for mitral valve repair. If these studies indicate the need, cardiac catheterization usually is recommended. If surgery is not needed at the time of initial evaluation, echocardiogram provides a simple method for ongoing evaluation. Cardiac Catheterization Both left and right heart catheterizations are performed on most patients being evaluated for valve surgery. Right heart catheteriza- tion usually employs a Swan-Ganz catheter inserted via a large vein into the right heart. Measurements of right-sided chamber pressures, the pulmonary artery pressure, and the pulmonary capillary wedge pressure (which reflects the left atrial pressure) are made. In a left heart catheterization, a catheter is passed from the femoral or brachial artery back though the aorta to the heart. It is used to measure pressures in the aortic root and left ven- tricular chamber. The gradient across the mitral valve is the differ- ence between simultaneous measurements of pulmonary capillary wedge pressure (the equivalent of left atrial pressure) and left ventric- 274 A. The valve areas then can be calcu- lated using the Gorlin formula that relates the area of the valve to the pressure gradient across the valve and the cardiac output. Coro- nary angiography is performed to look for any associated coronary disease that could be repaired simultaneously during surgery. In some younger patients and in some emergency situations, the information provided by the echocardiogram may be sufficient and heart catheter- ization may not be required. Therapeutic Intervention Indication for Surgery Decisions regarding the management of patients with valvular heart disease are based on the recognized progression of the various lesions and the risk versus benefit of surgical intervention. Until the ideal replacement valve is developed, the inherent risks associated with prosthetic valves (limited durability, need for anticoagulation, propensity for infection, sound) must be considered along with the risk of the operation itself. One pathologic situation (the deformed valve) is being substituted with another (the prosthetic valve when needed), although with a different array of potential problems. Associated coro- nary artery disease, especially in the presence of mitral regurgitation, significantly increases operative mortality. Thus, the decision is one of the benefits of preventing further deterioration in ventricular function, death, or other complications related to the valve disease versus the risk of surgery, the patient’s likelihood to regain or main- tain an acceptable lifestyle, and the risks inherent in the new valve substituted. Patients with new-onset symptoms are treated medically to relieve symptoms of congestive heart failure or angina. Congestive heart failure is treated with diuretics, digoxin, and afterload reduction when it can be tolerated. Great care must be taken in patients with aortic stenosis to avoid overdiureseis or too much preload reduction (with nitroglycerine and diuretics), which can result in inadequate filling of the left ventricle and subsequent syncope or low output. Heart rate must be controlled with beta-blockers digoxin or calcium channel blockers to permit adequate chamber filling, espe- cially when stenotic lesions are present. Anticoagulants are needed for patients in atrial fibrillation to prevent systemic embolization. There is some evidence that the use of the calcium channel blocker Procardia in asymptomatic patients with aortic insufficiency may delay their need for surgery. Once diagnostic studies have been completed, recommendations for chronic medical therapy or surgery are made. Heart Murmurs: Acquired Heart Disease 275 must be made on an individual basis and must involve an informed consent from the patient and family. Medical therapy is used for those patients when it is believed the surgical risk is too high or their long-term benefit is not sufficient for surgery. Others who are not yet ready for surgery receive medical therapy but are followed closely until indications for surgery become manifest. As noted, the surgical management of valvular heart disease is dependent on the risk-benefit ratio for the patient. Unfortunately, this is not always so clear when the risk of the operation is high and the benefit to an individual patient not clear. However, generalized indi- cations for surgery have evolved based on short- and long-term outcome studies. Detailed diagnostic and therapeutic guidelines are well summarized in “Consensus Statement on Management of Patients with Valvular Heart Disease,” developed by a combined task force of the American Heart Association and the American College of Cardiology. Any patient with symptomatic aortic stenosis should undergo valve replacement unless there are significant contraindica- tions or the patient’s life expectancy is otherwise severely limited. Even those patients with significant organ dysfunction secondary to the low output state may be considered. In the past, it also was believed those asymptomatic patients with aortic stenosis and a valve area of less than 1cm2 or a gradient >60mmHg also should undergo valve replacement. More recently, with the ability to follow patients closely with echocar- diography, surgery may be delayed until symptoms develop without increased risk to the patient as long as surgery occurs rapidly fol- lowing the onset of symptoms. Studies have shown that a patient with aortic insufficiency and a normal ven- tricle can undergo replacement with little surgical risk. On the other hand, once the ventricle begins to fail, the risk increases dramatically. Even in the absence of symptoms, increased operative mortality occurs in the presence of indicators of deteriorating ventricular function. At the present time, valve replacement is the recommended treat- ment for surgical correction of aortic valvular diseases. There are a few patients with aortic insufficiency in whom valvuloplasty has been successful, although replacement remains the standard. Spotnitz Mitral Stenosis and Mitral Insufficiency Mitral valve disease is different from aortic valvular disease in that reconstructive surgery often can be done instead of replacement of the valve. The operative mortality has been less with a repair when the long-term risks of a prosthetic valve are avoided. Mitral stenosis was the first valve problem approached surgically and was performed suc- cessfully in the late 1940s several years before the first successful use of the heart lung machine (by Gibbon3 in 1953). In any case, either direct commissurotomy and reconstruction, if needed, of the subvalvular apparatus are performed, or valve replacement is done. Because of the success of mitral valvuloplasty for mitral stenosis and the detailed diagnostic images of the valves now obtainable by echocardiography, certain patients with mitral stenosis are treated using percutaneous methods in the catheterization laboratory using balloon dilators (larger balloons but similar technique to angioplasty) with good success. Surgical treatment of mitral insufficiency is the most difficult con- dition about which to make decisions. Many patients are without symptoms despite large amounts of regurgitation and decreased left ventricular function.

Using the assumption that the normal allele frequency discount 50mg fertomid with mastercard menstrual cycle symptoms, p order fertomid 50 mg line women's health issues symptoms, is about 1 is not necessarily valid discount 50 mg fertomid otc womens health 6 week abs. With the application of the Hardy-Weinberg principle to this auto- somal recessive disease discount fertomid 50 mg mastercard women's health zumba, if 1/100 individuals are affected in a population, then q2 = 1/100 and q = 1/10, or 0. These alterations may involve the presence of extra chromosomes or the loss of chromosomes. Chromosome abnormalities are seen in approximately 1 in 150 livd births and are the leading known cause of mental retardation. It is diploid, showing both copies of each autosome, the X and the Y chromo- some. Chromosomes are ordered according to size, with the sex chromosomes (X and Y) placed in the lower right portion of the karyotype. Metaphase chromosomes can be grouped according to size and to the position of the centromere, but accurate identification requires staining with one of a variety of dyes to reveal characteristic banding patterns. Chromosome banding To visualize chromosomes in a karyotype unambiguously, various stains are applied so that banding is evident. G-banding reveals a pattern of light and dark (G-bands) regions that allow chromosomes to be accurately identified in a karyotype. Cytoge~etics Chromosome abnormalities in some cases can be identified visually by looking at the banding pattern, but this technique reveals differences (for instance, larger deletions) only to a resolu- tion of about 4 Mb. Submetacentric chromosomes have the centromere displaced toward one end (for example, chromosome 4). In these chro- mosomes, the p arm contains little genetic information, most of it residing on the q arm. Only the acrocentric chromosomes are involved in Robertsonian translocations, which will be discussed in this chapter. Gametes (sperm and • Triploid (69 chromosomes): egg cells) are euploid cells that have 23 chromosomes (one member of each pair); they are said to be haploid. Most somatic cells are diploid, containing both members of each pair, or 46 rare lethal condition chromosomes. Two types of euploid cells with abnormal numbers of chromosomes are seen in • Tetraploid (92 humans: triploidy and tetraploidy. Triploidy refers to cells that contain three copies of each chromosome (69 total)! Triploidy, which usually occurs as a result of the fertilization of an ovum by two sperm cells, is common at conception, but the vast majority of these conceptions are lost prenatally. These babies have multiple defects of the heart and central nervous system, and they do not survive. Tetraploidy refers to cells that contain four copies of each chromosome (92 total): This lethal condition is much rarer than triploidy among live births: Only a few cases have been described. Aneuploidy - Aneuploidy, a deviation from the euploid number, represents the gain (+) or loss (-) of a spe- cific chromosome. Two major forms of aneuploidy are observed: • Monosomy (loss of a chromosome) • Trisomy (gain of a chromosome) Autosomal aneuploidy Two generalizations are helpful: • All autosomal monosomies are inconsistent with a live birth. Trisomy is the most common genetic cause of spontaneous At least one X chromosome is required for survival. If more than one X chromosome is present, all but one will become a Barr body in each cell. The two important sex chromosome aneuploidies are Turner syndrome and Klinefelter syn- drome. Mosaicism in Turner Edema of wrists and ankles in newborn syndrome is thought to arise Cystic hygroma in utero resulting in excess nuchal skin and "webbed" neck in early embryogenesis by Primary amenorrhea mechanisms that are not Coarctation of the aorta or other congenital heart defect in some cases completely understood. The original cell is diploid for all chromosomes, although only one homolo- gous pair is shown in the figure for simplicity. When fertilization occurs, the conception will be a trisomy 21 with Down syndrome. The other gametes with no copy of chromosome 21 will result in conceptions that are monosomy 21, a condition incompatible with a live birth. In this case, the sister chromatids of a chromosome (for example, chromosome 21) fail to segregate (disjoiri). When fertilization occurs, the conception will be a trisomy 21 with Down syndrome. One gamete has no copy of chromosome 21 and will result in a conception that is a monosomy 21. Clinical Correlate: Maternal Age, Risk of Down Syndrome, and Prenatal Diagnosis Surveys of babies with trisomy 21 show that approximately 90% to 95% of the time, the extra copy of the chromosome is contributed by the mother (similar figures are obtained for trisomies of the 18th I and 13th chromosomes). I The risk of bearing a child with Down syndrome is less than 1/1,006 for women younger than 30. The I risk increases to about 1/400 at age 35, 1/100 at age 40, and 3-4% or more after age 45. There is no corresponding increase in risk with advanced paternal age; sperm cells are generated continuously throughout the life of the male. The increased risk of trisomy with advanced maternal age motivates more than half of pregnant women in North America to undergo prenatal diagnosis (most commonly, amniocentesis or chorionic villus sampling, discussed in Chapter 6). Down syndrome can also be screened by assaying maternal serum levels of a-fetoprotein, chorionic gonadotropin, and unconjugated estriol. This so-called triple screen can detect approximately 70% of fetuses with Down syndrome. At During Metaphase 2, each the end of Meiosis 1, each chromosome aligns individually daughter cell has one homolog. In Anaphase 2, sister chromatids migrate to opposite poles and each daughter cell gets one chromatid Figure 11-3-2A. Some alterations may result in a loss or gain of genetic material and are called unbalanced alterations; balanced alterations do not result in a gain or loss of genetic material and usually have fewer clinical consequences. As with other types of mutations, structural alterations can occur either in the germ line or in somatic cells. The latter, although not transmitted to offspring, can alter genetic material such that the cell can give rise to cancer. Translocations Translocations occur when chromosomes are broken and the broken elements reattach to other chromosomes. Translocations can be classified into two major types: reciprocal and Robertsonian. Reciprocal translocation Reciprocal translocations occur when genetic material is exchanged between nonhomologous chromosomes; for example, chromosomes 2 and 8 (Figure 11-3-3). If this happens during game- togenesis, the offspring will carry the reciprocal translocation in all his or her :cells and will be called a translocation carrier. Because this individual has all of the genetic material (balanced, albeit some of it misplaced because of the translocation), there are often no clinical consequences other than during reproduction. A Reciprocal Translocation In a translocation carrier, during gametogenesis and meiosis, unbalanced genetic material can Note be transmitted to the offspring, causing partial trisomies and partial monosomies typically resulting in pregnancy loss. During meiosis 1, the translocated chromosomes may segregate as Alternate Versus Adjacent chromosome 8 or as chromosome 2, producing a variety of possible gametes with respect to Segregation these chromosomes. The diagram in the upper right is used to depict the segregation refer to diagrams possible sperm the father can produce. It acknowledges that the translocated chromosomes can (Figure 11-3-4, upper right) potentially pair with either of the two homologs (2 or 8) during meiosis.
