In 1850, the Womens Medical College of Pennsylvania opened (Chin, 2002), Gender Differences in the Nursing Profession. In 1940, American female physician trained in the United States only 1% of nurses were men and in 1984, only 4%. Compared to women nurses, men are typically older This progress was not without controversy. In 1874, upon entering the field, more likely to be married, and Harvard professor Edward Clarke reported that women have a history of being in the military.

This number Australia surveyed patient gender preferences for nurse remained below 10% until the 1970s (Chin, 2002). Furthermore, this were also finally admitted into the American Medical was found to be particularly true for female patients Association (Chin, 2002). Federal legislation facilitated the increased cians practice in primary care settings such as pediatrics numbers of women in medicine into the 1970s and or internal medicine. This may lead to a need for more total pediatricians to treat patients (Cull et al. A typical medical school From 1988 to 1998, the income of women physi- curriculum lasts 4 years after completion of an under- cians was gaining on the income of men at a rate of graduate degree. However, ing and clinically based rotations in health care women in internal medicine still earn less than 80% of settings. Wallace and Weeks (2002) reported that the new doctors choice of generalist or specialty field.

The physicians in the United States experience more influence of women in medicine is suggested by burnout than their male U. Some The first publicly funded midwife training program of these career satisfaction differences may be due to the began in 1911 (Rooks, 1997). In the White House Conference on Child Health and Protection that same year, it was noted that trained midwives surpass the Midwives record of physicians in normal deliveries (Rooks, History and Training. However, by the 1930s, midwives attended only from mid or with and wife or woman (Rooks, one eighth of U. In early times, seen as a standard model of care in other developed midwives were also known as wise women or countries (Rooks, 1997). This was and in the United Kingdom there is a growing use of unpopular with the church, because of the belief that midwifery-led, freestanding birth centers (Brodie, 2002). In this same report, Australian midwives reported Midwives, as women healers, were felt to have feeling dominated by medicine as the amount of med- special knowledge about the female mystery of birth. There During the Middle Ages, midwives were persecuted for was also concern raised about difficulties in keeping up using pagan birth rituals, and witch hunts of the 1400s skills in rural areas, due to lack of continuing education and 1500s killed many midwives. Men were often excluded from child- professional midwifery, and in the poorer areas, birth, and male barber-surgeons were called in only 7095% of births are attended by traditional midwives. Women were not permitted to practice almost all births occur in hospitals, due to national surgery (Ehrenreich & English, 1973). Bridget Lee Fuller was a British midwife brought and breast-feeding are important advantages. In the United States, midwives were minority women or immigrants who approximately 99% of midwives are women (Rooks, had trained in other countries (Reed & Roberts, 2000). Although midwifery and medicine differ, there health professions, pharmacy has one of the highest are some similarities as well (Rooks, 1997). With current growth has been described as a celebration of life rather than trends, the proportion of women in pharmacy may a medical procedure (Romero, 2002) and the midwife eventually exceed the proportion of women in the tends to focus on the woman and the experience of nursing field (Francke, 1987). Women in pharmacy practice pregnancy include efforts for smoking cessation and are rather novel in the United States and the first domestic violence prevention.

Complications do occur to varying degree and include thyroid storm purchase 500 mg amoxicillin mastercard, wound haemorrhage cheap amoxicillin 250 mg on-line, hypoparathyroidism and recurrent laryngeal nerve injury. Wound haemorrhage although rare, (occurring <1%) can be very serious and life threatening especially if there has been arterial bleeding causing tracheal compression. Any sign of wound haemorrhage causing respiratory compromise requires urgent intervention Schwartz et al 1998). The occurrence of hypoparathyroidism post-operatively can be either permanent or temporary and is rarely due to mistaken removal of all four parathyroid glands, but rather interruption to their blood supply (Pattou et al 1998). In the hands of experienced surgeons performing a total thyroidectomy, the risk is thought to be between 0- 3% (Schssler-Fiorenza et al 2006). New techniques such as auto transplantation of parathyroid glands during surgery are effective at reducing these rates further (Testini et al 2007). Injury to the recurrent laryngeal nerve is also thought to be around 1-2% and is also higher when surgery is performed for thyroid malignancy. Some return of function to the vocal cords can be expected within the first few months and possibly up to 12 months. The first step in the treatment of either case is to discontinue amiodarone if it is safe to do so, for which a cardiology opinion is usually sought. Occasionally potassium perchlorate can be added or substituted if there is Treatment Modalities in Thyroid Dysfunction 179 no response. If successful the dose of thionamide is tapered and the thyroid function tests are monitored. Other treatments are based on clinical findings, such as broad spectrum intravenous antibiotics if infection is suspected and treating dysrhythmia or heart failure. Nasogastric tube may be required in individuals too ill to swallow and the drug can be administered intravenously if there are concerns over drug absorption. The use of glucocorticoids is generally accepted, especially if there is a suspicion of concomitant adrenal insufficiency and may have the additional benefit of lowering T3 levels by preventing peripheral conversion of T4 to T3 (Bahn 2011). In extreme circumstances if there has not been a satisfactory response to treatment, procedures such as dialysis and plasma exchange can reduce levels of thyroid hormone, but in practice are very rarely required (Alfadhi & Gianoukakis 2011). There remains much debate regarding the correct management of such patients, with a lack of firm evidence to support treatment at present. Aetiology of hypothyroidism The causes of hypothyroidism can be differentiated into primary thyroid failure or secondary central hypothyroidism caused by pituitary or hypothalamus failure. In clinical practice most cases are primary in nature, due to chronic autoimmune thyroiditis, which can be goitrous (Hashimotos thyroiditis) or non-goitrous (atrophic thyroiditis). Iatrogenic hypothyroidism is usually caused secondary to treatment of hyperthyroidism. Transient hypothyroidism may be seen following a post-partum thyroiditis or viral induced sub-acute thyroiditis as the thyroid begins recovery after a destructive phase in which stored thyroid hormone is released (Franklyn 1994). Clinical signs are also very variable, but if present give a strong suspicion of the disease. In frank hypothyroidism the decision to start treatment is straightforward but in subclinical disease, criteria to start treatment are more complex (detailed below). Assuming that a patients weight remains stable, with no alterations to their medication or change in co-morbidities, the dose of levothyroxine should in theory remain stable. There are several factors that require alterations in doses such as pregnancy, malabsorption and medication. Any state that produces intestinal malabsorption, such as coeliac disease, may lead to reduced uptake of thyroxine and hence a need to increase thyroxine dose. It is important to be weary of individuals who suddenly need an increase in thyroxine and who complain of gastrointestinal symptoms. Patients prescribed these medications should be advised to take them at least 2-4 hours apart from their thyroxine. Provided malabsorption is ruled out, a large dose of supervised levothyroxine replacement (1 mg/week) can be attempted, which fixes the problem in the majority (Grebe et al 1997). Main symptoms and signs in autoimmune hypothyroidism 184 Thyroid and Parathyroid Diseases New Insights into Some Old and Some New Issues 3. Prompt treatment with intravenous levothyroxine is required, initially with a loading dose, followed by smaller maintenance doses which can be given orally if the patient is able. No consensus exists as to whether T3 treatment should commence at the same time, or indeed if T3 alone is all that is required (Kwaku & Burman 2007). Caution is needed in the elderly, or those with cardiovascular disease due to increased risk of myocardial infarction and tachyarrhythmia. Concurrent use of intravenous glucocorticoids are usually required during initiation of thyroxine treatment due to the potential for evoking an adrenal crisis in the first few days as the hypothalamic-pituitary-adrenal axis is usually impaired in severe hypothyroidism. Other supportive measures include blankets to warm the patients slowly, cautious use of intravenous fluid to treat hypotension and a low threshold for broad spectrum antibiotics if infection is thought to be implicated. Consideration should be given early to intubation and mechanical ventilation if deemed appropriate, especially in a comatose patient.

Tuscano Abstract The myelodysplastic syndromes comprise a heterogeneous cluster of hematological stem cell disorders. The role of autoimmune pathogenesis is suggested by clonal expansion of cytotoxic T cells, as well as the response in many patients to immunosuppressive therapy.

The n-3 and n-6 are not interconvertible in the human body and are important components of practically all cell membranes buy amoxicillin 500mg on-line. The n-6 fatty acids and n-3 influence eicosanoid metabo lism buy generic amoxicillin 250 mg on-line, gene expression, and intercellular communication cell to cell. The polyunsaturated fat ty acid composition of cell membranes is largely dependent on food ingestion. Therefore, appropriate amounts of n-6 fatty acids and n-3 in the diet should be considered in making dietary recommendations. A balanced n-6/n-3 ratio in the diet is essential for normal growth and development and should lead to reduced car diovascular disease and other chronic diseases and improve mental health. The final recommendations are for Western societies, reduce the consumption of n-6 fatty acids and increased intake of n-3 fatty acids. Food sources in Mexico The main sources of ascorbic acid are presented in Table 1. The results of vitamin C are shown as the mean and correspond to the official tables of composition of Mexican foods. Fruits and vegetables Vitamin C is a major constituent of fruits and vegetables, which also contain citric acid, oxa lates and substances such as anthocyanins, coloring agents and carotenoids that are difficult to quantify when using colorimetric methods. Currently there is great interest in relation to consumption of natural foods and mainly on the content of nutrients in fruits, vegetables and vitamin C. This interest is due in part to vitamin C is probably one of the most widely used nutrients in the food and pharmaceutical industry. Used as a supplement, additive, preservative, as an antioxidant in processed foods. Acid content of ascorbic acid in different foods and different presentations 458 Oxidative Stress and Chronic Degenerative Diseases - A Role for Antioxidants In Table 3 shows the analysis of vitamin C in different parts of the food such as edi ble portion thereof, the seed or plant center and the shell and stalks that are normally discarded. Distribution of ascorbic acid (mg/100g) in some fruits and vegetables produced in Mxico Below the edible portion the moisture (%) is indicated in parenthesis. The data shown in Tables 3 through 6 are original and have not been published yet. It shows that even the concentration of vitamin C is lower in the edible portion in the shells report ed in Table 5. Content of ascorbic acid in the shell of some fruits and vegetables Table 6 shows the values of ascorbic acid in some plant species used as flavoring for Mexi can dishes. In most cases the amount used for the preparation of food is very low and some times do not amount to more than 2% by weight of the end plate. However their presence in cooked food gives organoleptic properties suitable for the acceptance of it and especially the potential of the flavors of food. For this reason, it may partially destroyed in foods during processing, if exposed to air during storage or if treated with water. The addi tion of ascorbic acid as an antioxidant should be appropriately marked in the list of ingredi ents on the label of the final product Ascorbic acid and its salts are practically insoluble in lipids (fats), for this reason that is often used in the food industry as an antioxidant and preservative greasy foods, in order to avoid rancid. Their salts are usually used with a solubilizing agent (usually a monoglyceride) to improve its implementation. Sodium ascorbate is a sodium salt of ascorbic acid (vitamin C) and formula C H NaO. This form is used in the food industry for their functions antiseptic, antioxidants,6 7 6 and preservatives. Ascorbyl palmitate is an ester formed by ascorbic acid (vitamin C) and palmitic acid creating a liposoluble form of vitamin C. It is wrong to think that is a natural antioxidant Use as a preservative Is usually used as a food preservative and as antioxidant in the food industry, a typical case is found as a bread improver additive. In industry collecting fruit prevents the color oxida tive change known browning. Is often added to foods treated with nitrite in order to reduce the generation of nitrosamines (a carcinogen), so commonly found in sausages and cold cuts. Ascorbic acid and its sodium, potassium and calcium salts are used widely as antioxidants and additives. These compounds are soluble in water, so that fats do not protect against oxi dation. For this purpose may be used ascorbic acid esters with fat soluble long chain fatty acids (palmitate and ascorbyl stearate). Signs and symptoms A frank deficiency of vitamin C causes scurvy, a disease characterized by multiple hemorrhag es. The diagnosis of scurvy, is achieved by testing plasma ascorbic acid, low concentration indicates low levels in tissues. It is generally accepted that ascorbic acid concentration in the layer of coa gulated lymph (20-53 ug/10 leukocytes) is the most reliable indicator of nutritional status re8 garding vitamin C and its concentration in tissues.
