Prevention Amenorrhea related to pregnancy, the female athletic triad, drug or alcohol abuse, or eating disorders is preventable insofar as these are lifestyle choices. Primary or secondary amenorrhea associated with genetic mutations or other systemic diseases or disorders is not preventable. Parental concerns about amenorrhea, however, should be directed to the underlying cause. Amenorrhea related to emotional stress, dieting, or excessive exercise usually goes away when the stress is relieved or when the girl makes appropriate lifestyle adjustments. On the other hand, amenorrhea associated with glandular disturbances, tumors, genetic or anatomical abnormalities, diabetes, or other systemic disorders is part of a larger and more worrisome picture. Over time, bone mass and strength are reduced leading to increased risk of fractures. Other articles you might like: While a missed menstrual period is the hallmark of early pregnancy, missing a period can be due to a number of factors and conditions. Primary amenorrhea (in which a woman does not begin menstruating) is very rare, while secondary amenorrhea (absence of periods in a previously menstruating woman) is much more common. Periods may also be irregular, with skipped periods, for the first few years after a woman has begun menstruating and in the perimenopause (the time period preceding menopause). A woman is not considered to have secondary amenorrhea until she has missed three menstrual periods in a row. However, the causes of secondary amenorrhea are generally the same factors or conditions that can lead to a skipped period. If a woman is not pregnant, a missed menstrual period may be due to a wide variety of both physical and emotional conditions that range from lifestyle stress to rare and serious diseases. Other causes of missed menstrual period Next Article Menstruation begins sometime during adolescence. Eventually, a woman should expect to experience a fairly normal cycle with very little variation from month to month. The only time we typically expect that a period will be missed is when a woman becomes pregnant. Amenorrhea may be diagnosed when a woman has missed three periods one after another. Girls who have not begun menstruation by age 15, as well, may be diagnosed with this condition which describes the absence of menstrual periods. Women who experience this condition may also develop symptoms such as: Troublesome acne Pelvic pain Excessive growth in facial hair Headaches Hair loss Discharge from nipples There are several potential causes for amenorrhea. Aside from pregnancy, factors such as stress and weight may affect the regularity of menstruation. During consultation for the absence of menstruation, your experienced Chicago gynecologist will consider these factors as well as others, such as hormonal imbalance. Imbalance in the proper function of hormones may be created by extremely low body weight, excessive exercise or excessive weight gain, a malfunctioning thyroid, or certain health conditions such as polycystic ovarian syndrome. Structural compromise within the pelvic region may also be the underlying cause of amenorrhea. Your physician needs to know the type and severity of your symptoms and information regarding your family medical history or other existing health conditions. Pregnancy is typically the first condition to rule out in the instance of amenorrhea. Our physicians may also arrange lab work that will measure hormone levels, focusing on male hormones like testosterone, and thyroid function tests, among others. Depending on the data gathered in consultation and early diagnostics, imaging may also be ordered to determine the cause of missed periods. Treatment for the absence of periods is designed around the cause of this condition. Prediabetes or elevated cholesterol or triglyceride levels causes a build up of fat on the liver that can lead to inflammation and decreased liver function. Choline also works to thin the bile so it can more easily flush fatpacking toxins from the liver.

Silver antibiotics in device coatings or materials have shown limited success so far in reducing the initial bacterial adhesion or in penetrating the biofilm matrix to achieve lethality. The reasons for this limited success are not immediately clear but may be related to the insufficiency of free silver ions released for antibacterial action in the devices. Much Lansdown 30 research is still needed to understand the mechanisms of bacterial resistance to silver in biofilm formation, why silver fails to penetrate the calcareous matrix and how silver interacts to influence natural human protective mechanisms. Metabolism and Toxicity of Silver in the Human Body Silver is not a trace metal and serves no physiological role in the human body [7]. Silver absorbed into human tissues from antiseptic respiratory sprays, implanted medical devices, wound dressings or indwelling catheters can be expected to reach the systemic circulation, mostly as a protein complex. Argyraemias are more frequent in people exposed to silver occupationally or by environmental exposures including food and drinking water. Theoretically, silver can be deposited in any tissue in the human body but the skin, brain, liver, kidneys, eyes and bone marrow have received greatest attention [14]. Current information shows that the uptake and metabolism of silver are not well documented and are largely limited to a few clinical studies with silver sulphadiazine, where blood silver levels of 300 g l 1 have been recorded [15, 16, 19]. Although silver released from intraurethral catheters is available for absorption through urinary tract membranes, the extent to which this occurs is not known. In these cases, primary attention is given to the influence of silver on bacteraemias and biofilm formation [24]. It is expected that as international regulatory requirements become more stringent, silver absorption data from a wide variety of products including textiles will become mandatory. The silver ion is absorbed through the gastro-intestinal tract and through the lungs following inhalation of silver dust and vapour possibly by passive diffusion of a silver-protein complex or by protein transfer in a form of endocytosis [14]. As much as 10% of silver sulphadiazine is absorbed through partial-thickness burns with exposure to high vasculature [19]. The intracellular metabolism of silver within human tissues is illustrated with reference to cells of a wound margin exposed to silver sulphadiazine. The silver ion absorbed into epidermal cells induces synthesis of the cystine-rich metalbinding proteins metallothionein 1 and 2. Metallothionein thus provides a double action, it protects tissues against the potential toxic effects of a xenobiotic metal Silver in Health Care 31 and promotes healing. It is expected that irrespective of the route of exposure, silver will bind to proteins in tissue fluids and exudates, particularly the albumins and globulins. These will be absorbed into the systemic circulation for distribution to soft and hard tissues. The rate of silver absorption is not known accurately for any route of exposure but silver in urine may provide a useful monitor for clinical or occupational exposure and absorption. Silver absorbed into the human body accumulates in a transitory fashion in the liver, kidney, brain, lung and bone marrow with minimal or no toxic risk. On the other hand, silver absorbed intestinally or from antiseptic sprays does accumulate in the cornea of the eye (argyrosis) and in the dermis of the skin (argyria), especially tissues exposed to solar radiation. Argyrosis and argyria attributable to fine deposits of silver metal or silver sulphide tend to be long lasting or permanent but not life threatening. Argyrialike symptoms have been seen in patients subject to chronic silver sulphadiazine therapy or long-term exposure to dressings releasing high levels of silver [14]. These black silver sulphide deposits in wound debris are not in my opinion a true argyria; they are rarely permanent, not present in living tissues and are normally lost as wounds heal. Silver or silver sulphide deposits in living tissues are rarely a cause for toxicological or physiological concern. In the liver and kidney which form the principal routes for silver excretion, silver granules accumulate in the cytoplasm of phagocytic cells, hepatocytes and renal tubular epithelium bound mostly in lysosomal vesicles. Silver is released into bile ducts and urinary ducts for excretion in the faeces and urine, respectively. Greater concern relates to the influence of chronic silver ingestion or silver sulphadiazine therapy on the bone marrow and circulating neutrophils [14].

These diagnoses are rare, so that only multicenter studies are likely to produce more robust data, comparing diet therapy to other treatments in a controlled manner, and/or establishing the best timing of diet trials. There is also very little information on the efficacy of diet treatment as first-line therapy. The difficulty of administration of diet therapy is likely to limit its acceptance in this position unless it becomes possible to induce ketosis without diet restrictions, that is, via a supplement or pill. Future, multicenter collaborative studies will be necessary to examine these possibilities. LennoxGastaut syndrome: a consensus approach on diagnosis, assessment, management, and trial methodology.

The ketogenic diet can be used successfully in combination with corticosteroids for epileptic encephalopathies. However, there are also several other genetic disorders that manifest with epilepsy for which dietary therapies appear to be especially effective, but for which the possible underlying metabolic mechanisms are not as clearly delineated. Seizure semiology includes all types, with generalized tonic-clonic occurring more frequently than complex partial and secondarily generalized seizures (Cardoza et al. Of these five patients, four of them had a 50% or better decrease in seizures, including one with a 75% decrease and one with a 100% decrease. All five of the patients who were able to tolerate the diet also had reported slight behavioral improvements. The most common lesions found in the brain include cortical tubers, subependymal nodules, subependymal giant cell astrocytomas, and radial migration lines. Seizures begin within the first year of life in 63% and prior to 3 years of age in 83% (Chu-Shore et al. The majority of patients have multiple seizure types, with the most common being complex partial seizures, followed by infantile spasms, generalized tonic-clonic seizures, and atypical absence (Chu-Shore et al. When surgical candidates are chosen carefully, good outcomes with seizure freedom can be achieved in about 60% (Zhang et al. For those patients who are not surgical candidates, or for whom the family does not wish to pursue surgical management, alternative epilepsy treatment options such as dietary therapy should be considered. Most patients are medication-refractory, with up to 77% of patients requiring combination medication therapy (Laan et al. This patient also had an improvement in her sleep pattern and reduced hyperactivity. The anticonvulsant effects of the ketogenic diet are probably multiple (Bough et al. Epilepsy is an especially common manifestation, occurring in over 85% of patients (Pascual-Castroviejo et al.

It implies a pathophysiologic process related to an abrupt decrease in myocardial oxygen delivery. It may be a marker of distal embolization with shedding of thrombogenic material from a complex plaque. The episodes of chest pain may be repetitive or intermittent with periods of exacerbation; episodes are promptly relieved by nitroglycerin. Syncope during an episode of chest pain is infrequent but strongly suggestive of the syndrome. Angina may be caused by microvascular dysfunction without detectable lesions or spasm in the large coronary vessels. The chest pain episodes are often triggered by emotional stress and commonly occur in clusters. Myocardial ischemia of a cardiac cause other than atherosclerosis develops in aortic valve stenosis, hypertension with left ventricular hypertrophy, hypertrophic cardiomyopathy, paroxysmal tachycardia, cocaine-induced chest pain, and congenital abnormalities of the coronary circulation. Non-ischemic cardiac causes of chest pain include pericarditis and aortic dissection. Non-cardiac, non-ischemic chest pain includes esophageal reflux and spasm, neuromuscular disorders, bronchopulmonary disease, and psychogenic factors. No historical points, physical examination findings, or tests are faultless in the diagnosis of angina. The cardiopulmonary physical examination may be totally normal in patients with stable angina, even during an anginal attack. The physical examination may also help diagnose other causes of chest discomfort, including costochondritis and pulmonary disorders, as well as non-ischemic causes of cardiac chest pain, including aortic dissection or pericarditis (see Table 38-2). Patients should be routinely evaluated for coronary risk factors, including an evaluation for hyperlipidemia (see Chapter 206), diabetes mellitus (see Chapter 242), and possibly, homocystine levels. However, these tests are not presently recommended for the routine care of individual patients. The appearance of a new mitral regurgitation murmur, a 10-mm Hg or greater drop in blood pressure, or typical anginal pain during exercise add to the diagnostic value. Commonly used in patients with recent myocardial infarction, unstable angina, or other conditions that are expected to limit exercise. The predictive value is influenced by the prior probability of ischemic heart disease (see Table 59-1) (Table Not Available). Myocardial scintigraphy can also localize the site of active ischemia in patients with more than one-vessel disease and hence help plan an interventional procedure (see Chapters 61 and 62). The sensitivity and specificity of perfusion scintigraphy using either the planar or the single-photon emission computed tomographic imaging techniques are generally somewhat better than for exercise electrocardiography. A false-negative result can be encountered in patients with three-vessel disease and global left ventricular ischemia. Echocardiography (see Chapter 43) with exercise has a sensitivity and specificity at least equivalent to those of exercise electrocardiography. However, this more expensive test is not widely available and generally is not needed for the diagnosis (see Chapter 44). Continuous electrocardiographic monitoring allows detection of otherwise clinically silent ischemia. Control of asymptomatic ischemia by approaches that rely on reduction of ischemic burden rather than focus on symptoms may improve prognosis in some patients with episodes of silent ischemia. These conditions should be recognized because they can be reversible with appropriate treatment. When selecting a diagnostic test (Table 59-6), it is important to realize that the predictive value of the test is dependent on the prevalence of the disease as determined by the Bayes theorem; thus, the post-test likelihood of coronary artery disease is influenced by the pretest prevalence of the disease. Other determinants of risk are older age, previous bypass surgery, previous myocardial infarction, and co-morbid conditions such as diabetes mellitus, renal failure, and obstructive coronary disease. The diagnosis requires careful clinical recognition followed by stratification of patients into groups at high, intermediate, or low risk of subsequent complications (Table 59-7).
