Problem Set 5 - Externalities and Efficiency Assignment

Problem Set 5 - Externalities and Efficiency - Assignment Example Use a supply and demand diagram to illustrate your answer and provide no more than five sentences of explanation. When prices are set below the equilibrium, i.e P2, there will be an increased demand in the houses by the population. Since supply remains constant as demand rises, there will be a shortage in the short run. However, in the long run, people will tend to build their own houses or property owners will develop more to avoid the shortages. This increases the supply of the houses and reducing shortages. (Figure: Market for Vaccines) The figure represents the market for vaccines with external benefits. The efficient level of output is __1,800______ vaccines, which is ___greater_____ than the markets output. 5. Suppose Tesco (A) and Sainsbury’s (B) both emit pollutants when producing their plastic bags used by customers to collect and carry their groceries home. The government enforces regulations saying that neither firm can release more than 10 units of pollutants. (Assume that pollutants can be measured in discrete and comparable units.) Currently Tesco releases 10 units and Sainsbury’s releases 11 units. The government requires Sainsbury’s to reduce its pollution by 1 unit – the company can do this, but at a cost of  £1,000. Tesco, however, can reduce its pollution by 1 unit for a cost of  £400. Sainsbury’s wants to save money by trading allowances with Tesco. After negotiations, Tesco agrees to see one unit of pollutant to Sainsbury’s for  £650. From the diagram, P1 and Q1 are the equilibrium price and quantity respectively. In the short run the time is too short for firms to adjust production. However, in the long run, firms will increase output to Q2 and charge high price P2 due to an increase in shock demand. This leads to demand curve to shift from D1 to D2. This will make the firms to make abnormal profits. Since there is free entry, the excess profits will attract more firms into the market.

The Hunger Games Essays That Shows Katniss Qualities Essay Example for Free

The Hunger Games Essays That Shows Katniss Qualities Essay Have you ever been taken away from your family and friends? Been forced into a game where to stay alive is the only way to win? The Hunger Games by Suzanne Collins is about sixteen year old Katniss Everdeen, who lives in the country of Panem from the far- off city called the Capitol. The Capitol divides in districts. It is harsh, cruel and keeps the districts in line by forcing them all to send one boy and one girl between the ages twelve and eighteen to participate in the annual Hunger Games until the end of the death and only one survive. Strength and kind Katniss faces challenges and survives the Hunger Games. Katniss has used her strength to try and get through the Hunger Games. When Peeta Mellark had gotten cut by Cato’s sword, he was deeply wounded. Katniss has to try and treat him in order to save his life. She runs toward the Cornucopia without cares of her own to get the bag pack of medicine that will survive Peeta’s life. Also, Katniss has bow and arrows that shows her strength. With her bow and arrows, she finds food and kills her enemies. She can do many things and can last longer throughout the Hunger Games. She acknowledges, â€Å"So I focus on the one really good thing that’s happened since I landed in the arena. I have a bow and arrows! A full dozen arrows if you count the one I retrieved in the tree. They bear no trace of the noxious green slime that came from Glimmer’s body†(197). She had also used bow and arrows when she was in District 12 to help support her mother and her sister, Prim. Along with her strength, she has also kindness for others that succeed her to win the Hunger Games. Katniss goes to the Cornucopia to get the bag pack of medicine that will help to save Peeta’s life. At the feast Clove attacks on Katniss but before killing her, Clove makes a foment about Rue. Thresh hears her and survives Katniss from Clove. He doesn’t kill Katniss because Katniss was rue ally and he feels that he owes her. Katniss acknowledges, â€Å" I decorate her body in the flowers. Covering the ugly wound. Wreathing her face. Weaving her hair with bright colors†(237). That shows Katniss loves Rue because she looks like Prim. In conclusion, the author wants to show us how we can face difficult problems in our life with the help of our qualities. If we have good qualities, we can win every challenge. I have a friend who lives in country of India, city is called Bihar. Bihar government is very cruel and harsh. The political status of this city is not good. Bihar city is poor and struggling with food poverty. The people of Bihar are controlling by their government. The girls cannot go to schools and colleges in this city. My friend has very intelligent and has good qualities. She is president of team that is against the government of Bihar. They use their strength and power to change the rules of their city. Finally, they succeeded in their challenge. Like those People or Katniss we can use our qualities to succeed in our life.

Abnormal Uterine Bleeding (UAB) In Gynaecological Practice

Abnormal Uterine Bleeding (UAB) In Gynaecological Practice INTRODUCTION Abnormal uterine bleeding (AUB) is a common complaint in gynaecological practice, represents a major proportion of out patients attendence. One, in 20 women in UK consulted their GP for menorrhagia. [1] A menstural cycle of fewer than 21 days or more than 35 days or a menstural flow of less than two days or, more than seven days is considered abnormal. [2] AUB can be categorized as excessive menstural bleeding, irregular, bleeding intermenstural including, postcoital bleeding. [3] Different terms, used to describe AUB are: oligomenorrhea (bleeding occurs at intervals of > 35 days usually caused by, prolonged follicular phase). Polymenorrhagia, (bleeding occurs at intervals of 21 days may be caused by a luteal phase defect). Menorrhagia, (bleeding occurs at normal intervals (21 to 35 days)but with heavy flow (80 ml) or duration (7 days). Menometrorrhagia, (bleeding occurs at regular, non cyclic intervals with heavy flow (80 ml). (2) Abnormal uterine bleeding, includes both DUB bleeding from structural causes. Dysfunctional bleeding can be anovulatory, which is characterized by heavy but regular periods. (I-e, menorrhagia). Structural causes include: fibroids, polyps, endometrial carcinoma pregnancy complications. Abnormal bleeding can also results from contraceptive methods. (4) In peri postmenopause women, it is essential to exclude endometrial carcinoma. In younger women, endometrial hyperplasia anatomical anomalies: such as uterine fibroids, comprise the main pathology. (5) Perimenopause is the period, 2 8 years preceding menopause 1 year after the final menses. (WHO). However, a better practical definition is, the phase preceding the onset of menopause, generally occurring around 40-50 years of age, during which the regular cycle of a women transition to a pattern of irregular cycles. (6) A variety of methods, have been used to investigate patients with AUB, such as, endometrial cytology, transvaginal ultrasound, hysteroscopy, D C and endometrial biopsy . (7) The recommendation regarding, investigation of AUB is that women, over the age of 45, should be investigated with endometrial biopsy. Frequently, this is performed as an inpatient procedure with the biopsy being obtained by uterine curettage (D C). (5)This is the most common procedure used, to evaluate the endometrial cavity of a patient with AUB. (8) However, the value of endometrial curettage is great, in the establishment of histopathologic diagnosis. (6) The operation involves a G. A often a two day stay. Originally, the procedure was thought to have a therapeutic effect or AUB, But studies have failed to support this. This procedure is performed for diagnostic purposes, to exclude endometrial malignancy. (9) REWIEW OF LITERATURE ABNORMAL UTERINE BLEEDING Abnormal uterine bleeding (AUB) is a symptom it is not a disease, but is a common debilitating condition. Dysfunction uterine bleeding (D. U. B) is the diagnosis, given to women with AUB in whom no clear etiology can be identified. [10, 11]. An approach accurate diagnosis depend on recognizing the following types: Menorrhegia: is cyclic bleeding at normal intervals, which is excessive is larger than 7 days o and amount more than 80 ml frrom normal secretory endometrium after normal ovulation is caused by conditions affecting the uterus. (10, 11) Polymenorrhea: is cyclical bleeding which is normal in amount but which occurs at too frequent intervals of Polymenorrhegia: is cyclical bleeding which is both excessive too frequent. Eg: 9/20-12/20. It implies a disturbance in the hypothalamic pituitary ovarian uterine axis. (10) Metrorrhegia: It is bleeding of any amount whch is cyclical which occur irregularly or continuously in between normal cycles. It is caused by benign or malignant growth with ulcration. (10) Dysfunctional Uterine Bleeding continuously occurs at the extreme of reproductive (adolesence perimenopausally). The abnormalities of ovarian activity may be classified as follows. Upto 90% of cases of DUB result form menstrual cycles in which ovulation does not occur (anovulation) (Dodds). The remainder of cases arise from problems associated with ovulation such as dysfunction of the corpus luteum or prolonged progesterone secretion. (12) Anovulatory Occasionally anovulatory cycles occur in all women. Upto 90% of cases of D. U. B result from menstural cycles in which ovulation does not occur(anovulation. The remainder of cases arise from problems associated with ovulation such as dysfunction of the corpus luteum or peolonged progesterone secretion. Chronic anovulation in associated with an irregular unpredictable pattern of bleeding ranging from short cycles with scanty bleeding to prolonged period of irregular heavy loss. In anovulatory cycles, the endometrium is unable to produce factors whose sysnthesis is controlled by progesterone, eg. PGF2a (Smith et al, 1982). This may account for the painless bleeding. Anovulatory bleeding may be associated with cystic glandular hyperplasia of the endometrium. This occurs in some older women also in peripubertal girl, where unopposed oestrogen secretion occurs. Endometrial hyperplasia may cause excessive bleeding, anaemia, infertility even endometrial carcinoma. (13) Ovulatory: (idiopathic bleeding) It appears that there are a number of endometrial products, which alters the degree of vadoconstriction thus may effect the volume of menstrual blood loss. In the mid 1970s, a relationship b/w prostaglandins (PG) production menorrhegia was suggested by work showing that total endometrial PG content was proportional to menstrual loss. It appears that a shift in endometrial conversion form the vasoconstrictor PGF20( to the vasodilator PGI2 occurs. Another important factor is endothelin, which is very potent vasoconstricter, produced within the endometrial vessels. Marshs group showed reduced endothelin immunostaining in the endometrium of women with monorrhegia , implicating this peptide in the pathophysiology of increased menstural blood loss. (Marsh 996) (13) Etiology of Abnormal Uterine Bleeding Before Menarche: Malignancy, trauma sexual abuse or assault are potential causes of abnormal uterine bleeding before menarche. Child bearing years: Pregnancy is the first consideration in women of childbearing age who present with AUB. Potential causes of pregnancy related bleeding includes miscarriage, ectopic pregnancy , placenta previa, abrutio placentae trophoblastic disease. Next, iatrogenic causes of AUB should be explored. Bleeding may be induced by medication, including anticogulants, selective serotonin reuptake inhibitors, antipsychotics, cortiosteriods, hormonal medication, tamoxifen (Nolvadex). Herbal substance including ginseng, ginko, soy supplement, may cause menstrual irregularities by altering estrogen levels or clotting parameters. (14), (15) Systemic Disorders: Includes thyroid, hematologic, hepatic, adrenal, pituitary, hypothalamic conditions menstural. Irregularities are associated with both hypothroidism (23. 4% of cases) hyperthyroidism (21. 5% of cases). Coagulation Disorders: Inherited coagulopathy may be the underlying cause of AUB in 18% of white women 7% of black women with menorrhagia. Others causes include polycystic ovary syndrome or diabetes mallitis present with obesity, acne, hirsutism acanthosis nigricans. Genital tract pathology may be associated with intermenstural, postcoital and heavy menstural bleeding, Any history of abnormal Papanicolaou (Pap) smear, sexually transmitted disease, gynaecologic surgery, trauma or sexual abuse should be elicited. Uterine fibroids, endometrial polyps, adenomyosis, endometrial hyperplasia and atypia and endometrial cancer should be excluded. [14, 15] Differential Diagnosis Pregnancy complications: Threatened abortion   Incomplete abortion   Ectopic pregnancy Nonuterine bleeding: Cervical ectropion/erosion   Cervical neoplasia/polyp   Cervical or vaginal trauma   Condylomata   Atrophic vaginitis   Foreign bodies Pelvic inflammatory disease (PID): Endometritis   Tuberculosis Local factors: Endometrial polyps   Endometrial neoplasia   Adenomyosis/endometriosis   Uterine myomata (fibroids)   Intrauterine device (IUD) Uterine sarcoma Coagulation disorders: Thrombocytopenia, platelet disorders   von Willebrand disease   Leukemia   Ingestion of aspirin or anticoagulants   Iatrogenic Causes: Anticoagulants Antipsychotics Corticosteroids Herbal other supplements(ginkgo, soy) Hormone replacement intrauterine devices Oral contraceptive pills Thyroid hormone replacement PATHOPHYSIOLOGY OF ABNORMAL UTERINE BLEEDING: The hallmark of normal menstrual bleeding is the final result of fluctuations in the hypothalamic-Pituitary-Adrenal-Ovarian axis leading to predictable denudation and slough of the endometrium. Hemorrhage followed by prompt hemostasis and repair causes stabilization and regrowth of the endometrium. Physiologically, constant flow levels of estrogen prime the endometrium. Normal secretion of progesterone from the corpus luteum stabilizes the endometrium, decreases vascular fragility and supports the endometrial stroma. Patients with menorrhagia typically have an imbalance of prostaglandins levels and increased fibrinolytic activity . Specifically, women with heavy bleeding often have elevated levels of plasminogen activators compared to those with normal menstruation. [16] An intact coagulation pathway is important in regulation of menstruation. Mensturation disrupts blood vessels and in the face of normal hemostasis, the injured blood vessels are rapidly repaired . Restoration of blood vessels requires successful interaction of platelets and clotting factors. Defficiency of platelets, abnormal platelet function and an intact coagulation pathway may be associated with profound changes in the menstrual ctcle. [16]. Anovulatory D. U. B is usually due to failure of the corpus luteum to sustain the developing endometrium. The decline of inhibin levels and rise in FSH levels reflect the loss of follicular activity and competence as the perimenopausal transition occurs, [16]. Ovulatory D. U. B occurs when ovulatory cycles coexist with intracavitary lesions including polyps, endometrial cancer or fibroids which cause erractic bleeding, [16]. NATURE OF ABNORMAL UTERINE BLEEDING: The studies have shown mean menstrual blood loss to be ~ 30 ml per cycle in most societies, with loss > 60-80 ml per month being associated with an increased tendency towards iron deficiency and anaemia( Hallberg ET AL, 1996 ;Code et al, 1971). An upper limit of 60 ml may be more appropriate clinically. [17]. The duration of normal menstruation also varies greatly, with an average of 5 days and the heaviest loss usually on the first 2 days(Matsumoto at al, 1962 ; Rubin and Crosignani, 1990). Duration of flow is considered abnormal when it lasts 7 days. [17]. Abnormal uterine bleeding may involve any disturbance of regularity, frequency, duration or volume of menstrual flow and the causes may be physiological, pathological or pharmacological (Fraser and Sngertekin, 2000), [17]. MECHANISM S INVOLVED IN AUB: MENORRHAGIA: Menorrhagia is caused by certain pelvic diseases. The mechanisms by which these conditions cause excessive bleeding are poorly understood, but evidence suggest that large , thin walled and fragile surface vessels underlies the menorrhagia occurring with myomata and endometrial carcinoma. This disturbed angiogenesis is most likely a consequence of unco-ordinated release of angiogenic factors from the tumor themselves(Jane and Harris, 1998), s/a VEGF, bFGF, TGF-beta( Stewart and Nowak, 1996)[17]. The mechanism of increased blood loss with copper IUCDs is thought to be due to a combination if increased cytokine- producing endometrial leukocytes ( Sheppard, 1987), increased local fibrinolytic activity and epithelial surface erosion due to contact with the device(Shaw et al, 1979_. Release of PG and activation of mast cells and macrophages may be the underlying mechanisms. [17]. A quantitative reduction in platelets s/a in autoimmune thrombocytopenia or chronic renal failure can lead to increased menstrual loss. DYSFUCTIONAL UTERINE BLEEIDNG: Dysfunctional uterine bleeding accounts for ~50% of all cases of excessive uterine bleeding, 9Barley, 1972)[17] Anovulatory Dysfuctional Uterine Bleeding: The exact mechanisms behind anovulatory bleeding are unknown(Fraser et al, 1996) but it is known that unopposed estrogen can lead to excessive endometrial proliferation and hyperplasia with increased and dilated draining veins and suppression of spiral arterioles ( Beilby et al , 1971). Large thin walled, tortuous, superficial endometrial vessels can often be demonstrated on the surface of hyperplastic endometrium(Hamou, 1985) and increased fragility is a probable contribution to increased blood loss. Unopposed estrogen has a direct effect on the uterine blood supply by reducing vascular tone (Fraser at al, 1987) and possibly an indirect effect through inhobiting vasopressin releae( Akerlund et al, 1975) leading to vasodilation and increased blood flow. Unopposed estrogen also stimulates stromal VEGF expression which may contribute to disturbed angiogenesis ( Zhang at al, 1995 ; Smith , 1998). [17]. Ovulatory Dysfunctional Uterine Bleeding: The main defect in ovulatory DUB appears to be in the control of processes involve in the regulation of the volume of blood lost during menstrual breakdown of the endometrium, primarily the processes of vasoconstriction and haemostasis. [17] Endometrial glandular and stromal estrogen and progesterone receptor levels may be increased in the late secretory phase in women suffering from DUB (Gleeson et al, 1993 )[17] There may be some role of endothelins, which increase in at the time of normal menstruation. ( Cameron et al , 1992)[17] Reduced levels of endothelins may lead to an increase in the volume of blood lost. An increase in total PG release and disappropriate rise in PGE2 have been demonstrated in ovulatory DUB (Smith et al, 1981 ). It also has been shown that there is an increase in PGE2 and PGI2 receptors predisposing to vasodilation, in women with menorrhagia ( Adelantado et al, 1988 )[17] Prevention of platelet aggregation by PGI2 release may be an important contributing factor in ovulatory DUB ( Smith et al, 1981 ) as may increased endometrial tPA content, increased local fibrinolytic activity ( Bonner et al, 1983;Casslen et al, 1996;Gleeson et al, 1993 ) and excessive endometrial heparin like activity ( Paton et al , 1980 )[17} Endometrial lysosomal enzyme activity in women with ovulatory DUB is increased, and this activity is also observed in women with menorrhagia secondary to IUCD use (Wang , 1994 ){17 ) Matrix metaloproteinases may be important in contributing to abnormal endometrial breakdown and abnormalities of menstrual bleeding ( Salamonson et al, 2000 ){17, 18 ]. Granulated stromal lymphocytes, macrophages and othe migratory leukocytes may contribute to mechanisms of excessinve loss. [18] In DUB, delayed or incomplete endometrial repair could prolog menstrual bleeding episodes, but nothing is known about such mechanisms. [18] SIGNS AND SYMPTOMS OF ABNORMAL UTERINE BLEEDING: Frequent complaint include: heavy or prolonged menstural flow, social embarrassment, diminished quality of life, sexual compromise and alteration in life style. Pain is not a common presenting symptom unless associated with passage of large blood clots. Prolonged menstrual blood loss can be associated with anaemia. Typical complains of anaemia include fatigue, unusual desire of eating starch or dirt and headaches. Severe anaemia may cause fainting, congestive cardiac failure, exercise induced fatigue, shortness of breath. Hemorrhagic shock death are rare sequelae for DUB. [16] EVALUATION OF AUB IN PERIMENOPAUSAL WOMEN: 1.  History: History focuses on identifying the type of AUB:ovulatory, anovulatory or anatomic in order to guide treatment. Ovulatory bleeding is more common, usually cyclic, and can be associated with mid cycle pain, premenstrual symptoms and dysmenorrhea. Anovulatory bleeding occurs more frequently at the axtremes of reproductive age and in obese women. It is usually irregular and often heavy. Any history of easy bruising and tendency to bleed suggests coagulopathy. History of jaundice and hepatitis gives the evidence of liver sisease. [19] 2. Physical Examination: Physical examination includes looking for evidence of systemic disease. Pelvic and bimanual examination are done to detect disease in the genital tract. Cervical cytology analysis should be current and normal and cervical and vaginal swabs should be assesses to rule out infection. [19] 3. Laboratory tests: Beta subunit human chorionic gonadotropin for pregnancy. Complete blood count with platelet count for coagulopathy LFT, PT for liver disease. TSH for hypothyroidism and hyperthyroidism. Free testosterone for ovarian or adrenal tumor. [19] 4. Assessment of the uterine cavity: The main indications for assessment of the uterine cavity is to exclude pathology, most often seen in women over 45 years of age with anovulatory cycles. [19] A wide variety of methods are available for endometrial assessment including: Ultrasonography Endometrial Biopsy Hystroscopy Dilatation and curettage Sonohysterography Hysterosalpingography 1. Ultrasonography: Ultrasonography to look for ovarian or uterine disease. Transvaginal ultrasound is 80% sensitive and 69% specific for fibroids and polyps and is superior to transabdominal ultrasound. If possible, transvaginal ultrasound should be performed on days 4-6 of the menstrual cycle. [19] 2. Endometrial Biopsy: Endometrial biopsy is a simple office procedure that can be done by family physicians, [19]despite its convenience , cost effectiveness and safety, it is a blind endometrial sampling procedure. [20]It is a useful method to exclude malignancy in perimenopausal women. The annual incidence of endometrial cancer is 19. 5 per 100, 000 women. One in 4 cases of endometrial carcinoma occurs before menopause, so biopsy should be considered for high risk premenopausal patients, even in the presence of fibroids. Endometrial biopsy produces an adequate sample more that 85% of the time and detects 87-96% of endometrial carcinoma. [19] 3. Hysteroscopy: Hysteroscopy permits direct visualization of the cercical canal and uterine cavity, enabling observation of intrauterine abnormalities. Hysteroscopy is considered an accurate gold standard in uterine cavity evaluation. Despite the lack of adequate information about the diagnostic accuracy, it is used in many studies with and without endometrial sampling as a reference standard, [21] Hysteroscopy was reported to have sensitivity, specificity, negative predictive value (NPV) and positive predictive value (PPV) of 94. 2, 88. 8, 96. 3 and 83. 1% respectively, in predicting normal or abnormal endometrial histopathology (Garuti et al, 2001). The highest accuracy of hysteroscopy was in diagnosing endometrial polyps, where as the worst result was in estimating hyperplasia. In a recent study the sensitivity and PPV of hysteroscopy without endometrial biopsy in diagnosing endometrial carcinoma was only 58. 8 and 20. 8 % respectively (Lo and Yuyen, 2000 ). There, since the incidence of focal lesions in patients with AUB is 46-74% (Nagele et al, 1996;Pal et al, 1997 ), it seems that the most cost effective approach is to proceed with hysteroscopy complemented by endometrial biopsy, early in the assessment of AUB. [22] 4. Dilatation Curettage: Dilatation is a common surgical procedure done on women to scrape and collect the tissue from inside the uterus. Dilatation is a widening of the cervical passage. This is done using smoothy conical and tapered, graduated metal rods of various sizes and these appropriately called the dilators, which dilates the tight cervical passage slowly. Curettage is the second part of the procedure and is done to scrape the inside contents of the uterus. For this, a sharp spoon like instrument called curette is used. The procedure is usually performed under general anaesthesia. [23, 24, 25] Indications:[23, 24, 25]s Dialtation and curettage may be done as a diagnostic or a therapeutic procedure. Diagnostic: Diagnose conditions by collecting tissue samples for biopsy. To diagnose endometrial cancer. To investigate the causes of infertility. To investigate the cause of abnormal bleeding in postmenopausal women taking HRT. Therapeutic: Treat intermenstural bleeding To remove polyps in the endometrial or inner lining of the uterus. To treat irregular and heavy bleeding. To remove an embedded IUD used for contraception. To perform abortion in the early stages of pregnancy. To evacuate spontaneous abortion product. [23, 24, 25] Preoperative procedure: It is recommended that the patient take nothing by mouth, for at least 6 hours. Pain killers and antibiotics may be prescribed before the procedure. A sedative may be useful to relieve the anxirty of srgery. The genital area may be shaved and prepared for the surgery. An enema may be administered to clear the bowels. [23] Anaesthesia: General Anaesthesia: Most D Cs are done under general anaesthesia. The procedure is normally very short and the general anesthetic can be quickly reversed, with the patient going home soon afterwards. Spinal Anaesthesia: The advantage of spinal anaesthesia is that the patient is awake but at the same time does not have any sensation below the waist. It avoids all the complications of general anaesthesia. Local Anaesthesia: Occasionally, D C s are done under local anaesthesia, if the patient is not ready for general or spinal anaesthesia. [23, 25] Procedure: The vagina and cervix are cleaned with an antibacterial solution that may be iodine or alcohol based. The cervix is visualized using an instrument that is locatedin the vagina called the speculum. Lights are so adjusted to visualize the cervix so that its upper lip can be grasped with a special curved forceps called the Vulsellum. This helps both in stabilizing and bringing the cervix down towards the vaginal opening to ease with rest of the procedure. Dilatation is next done using sequential metal round tapered dilators and the opening to the uterus is gradually widened to about the size of a large pencil. Once this dilatation has been completed, the curette is inserted into the uterine cavity and is used to gently scrape the lining of the uterus. When the surgeon feels the gritty layer of cells just above the muscle of the uterus, then he/she knows that the scrapping has gone deep enough to sample the tissue adequately. This scrapping is done throughout the uterus and the tissue is sent to histopathologist. [23, 24, 25, 26] Post operative care: There may be mild abdominal discomfort after a dilatation and curettage, if pain is severe, consult a doctor. Medication should be taken as advised by doctor. Ensure to take antibiotics. Avoid the use of any contraceptive device or sexual intercourse for a week. Use sanitary napkins during this time period. If there are any signs of infection s/a fever , pain or discharge, consult the doctor immediately. [23, 24, 25] Contraindications: If a patient is too ill to undergo surgery. If the patient is unable to move her legs apart, s/a with severe arthritis in the hips. If the patient has problem with clotting mechanism of the body. [23] Complications: Complications are usually rare: Anaesthetic Complications: Reactions to anaesthetic medications. Breathing difficulties. Surgical Complications: Perforation of the uterus. Laceration of the cervix. Scarring of the endometrium. Infection of the uterus or other pelvic organs. Hemorrhage. [23, 24, 25] 5. SONOHYSTEROGRAPHY: Sonohysterography is being used more frequently for evaluation of women with many gynaecologic conditions. In 1992, it is reported the use of sonohysterography for detecting endometrial polyp in 14 of 148 infertility patients. In 13 of the women, polyps were asymptomatic. [27]This procedure is to be done by use of saline infused through a catheter into the endometrial cavity provides slight distention and separation of cavity walls, allowing the better visualization of uterine cavity. [28] Sonohysterography not only aids in diagnosis of intrauterine pathology but also in decision regarding surgical versus medical management of patients and and directs the approach and instrumentation required when surgical treatment is warranted. [28] It can be performed in any phase of cycle but the best time is during the first phase of the cycle especially when the indication is sterility or thickened endometrium at transvaginal sonography. [28] 6. HYSTEROSALPINGOGRAPHY: Hysterosalpingography requires the use of radiations and iodinated contrast material. It is expensive and provides indirect information about the uterine cavity. One can delineate fibroids and polyps but cannot comment on endometrial thickness. [28] 7. MEGNETIC RESONANCE IMAGING: Magnetic resonance imaging , an expensive modality provides excellent images of the uterus and myometrial pathology disrupting the endometrium, however, intracavitary lesions are not well demonstrated. [28] EMBRYOLOGY OF THE FEMALE GENITAL SYETEM Although genetic sex is determined at fertilization, gender is not apparent until approximately the 12th week of embryonic life. By the 6th week embryonic life, both male and female embryos start to develop the following structures on either side of the midline. :[29, 30] Genital ridge (proliferation of coelomic epithelium ) Mesonephric (wolffian )duct (lateral to the genital ridge ). Paramesonephric ( mullerian ) duct which consists of: Upper vertical part lateral to the wolffian duct. Middle horizontal part crosses in front of the wolffian duct ( both upper and middle parts form the fallopian tubes ). Lower vertical part fuses with the similar part of the opposite side to form the uteri-vaginal canal (the upper part forms the body and cervix of the uterus while the lower part forms the upper 4/5 of the vagina ). The lower 1/5 of the vagina develops from the sino-vaginal bulbs in the posterior wall of the uro-genital sinus. [29] Origin and derivatives of the Mullerian Ducts: Mullerian ducts persists, in females to develop into the fallopian tubes, the uterus and part of the vagina. [31]. Mullarian duct grows , at first it is solid, but later it becomes canalized. It deviates more and more medially till it meets its fellow of the opposite side. The septum between the two mullerian ducts disappear. The proximal parts of the mullerian ducts form the fallopian tubes, while the distal parts meet together to form the body and cervix of the uterus and the upper 4/5th of the vagina. The stroma and muscles develop from the surrounding mesoderm. The fusion of the two mullerian ducts brings together two peritoneal folds which become the broad ligaments. [29] Ovary: Development of the ovary passes into three phases: Migration of the germ cells from the yolk sac to the posterior body wall at level of 10th thoracic level to enter the genital ridge The germ cells differentiate into oogonia then primaryoocytes and become arrested until puberty. Descent of the ovary to reach the pelvis along a ligamentous cord called the gubernaculums that is attached inferiorlyot the inguinal region. The gubernaculums becomes incorporated into the uterine wall at the point of entry of the fallopian tube and persists in the adult as the ovarian ligaments and the round ligament. [29] External Genitalia: Clitoris develops from the genital tubercle (by slight elongation ). Labia minora develops from the genital folds (by remaining separate ) Labia majora develop from the genital swelings (by enlarging greatly ). Vestibule develops from the lower most part of the urogenital sinus. [29]. ANATOMY AND HISTOLOGY OF FEMALE GENITAL TRACT Uterus: The uterus is a fibromuscular organ and is a hollow and pear shaped highly vascular organ present in the pelvis between the bladder and the rectum. It is about 8 cm long and 5 am broad, within which fetal development occurs. Uterus is usually divided into a lower cervix and an upper corpus of uterine body. 1. Cervix; The cervix is narrow region at the bottom of the uterus that leads to the vagina. It has a convex round surface with a circular or slit like opening (the external os ) into the endocervical canal, ehich is approximately 2 -3 cm in length and opens proximally into the endometrial cavity at the internal os. [30, 32, 33] Histologically, the cervical mucosa generally contains both stratified squamous  epithelium (exocervix) and mucus secreting columnar epithelium (endocervix). The mucus secreting glands are confined to the endocervix. The area where the two types of epithelia meet is called the squamocolumnar junction. [30, 34]. Cervical mucus secreted by the mucosa layer of the cervical canal serves to protect against bacteria entering the uterus from the vagina . [33]. In the cervix, the stroma is firmer, more fibrous and less cellular. [34] 2. Uterine Corpus: The body of the uterus varies in size. At birth , the cervix and corpus are approximately equal in size, in the adult women, the corpus has grown to 2-3 times the size of the cervix. The uterine corpus is divided into different regions: Isthmus: where the endocervicla canal opens into the endometrial cavity. Uterine cornu: Funnel shaped area on each side of the upper uterine body receives the insertion of the fallopian tubes. Fundus: The portion of uterus above uterine cornu. [30] Histologically, the wall of the uterus consists of the following three layers: Perimetrium: It is serous membrane that covers the outside of the uterus.

Young Goodman Brown Looses Faith in The Woods    In the story "Young Goodman Brown," written by Nathaniel Hawthorne, the author introduces evil images to tempt and delude Young Goodman Brown as he made his way through the woods. Goodman Brown, by the end of his journey, understands there is an evil side to human nature and believes that man is doomed by "original sin."    The main character, Goodman Brown is introduced as a well-mannered man who is happily married to Faith. Initially, the language such as "sunset" and "pink ribbons" symbolizes light and a positive environment in Salem Village, where the story takes place. Then, as Goodman Brown journeys through the woods, changes in the environment make him change the way in which he sees the world and people around him.    From the time he decides to go to the woods at night, this peaceful panorama presented in his hometown changes. Evil images like "devil, lonely thick boughs, "1 add an obscure and negative side to the story. He had taken a dreary road, darkened by all the gloomiest trees of the forest, which barely stood aside to let the narrow path creep through and closed immediately behind (p. 62).    This example reflects the change in environment for Goodman Brown after he left the positive world of the village. He felt he was passing through an unseen multitude since he could not know if there was someone concealed by the trees. This situation makes him question: "What if the devil himself should be at my very elbow" (p. 62). Goodman Brown, who wasn't aware of the existence of an evil side to the world, is being introduced to it through the natural objects in the woods, which provided a warning sign of the evil to come.    S... ...ream" (p. 70). Now the natural world and even his wife and fellow Puritans reveal a concept of evil to him. This makes him lose his faith in his religion and his own people. "My faith is gone! ... There is no god on earth; and sin is but a name. Come devil; for to thee is this world given" (p. 67). Whenever the minister talked about the sacred truths of religion, with the bible in his hands: "...then did Goodman Brown turn pale, dreading lest the roof should thunder down upon the gray blasphemer and his hearers" (p.70). His new attitude towards life in the village is a measure of his acceptance of the idea that man is doomed by "original sin."   Work Cited Nathaniel Hawthorne, "Young Goodman Brown," in Literature: Reading and Writing the Human Experience, eds.

Relationship Between Religious Beliefs Essay

‘The relationship between religious beliefs, religious organisations and social groups is complex and diverse. Different groups have different needs and priorities.’ To what extent do sociological arguments and evidence support this view? Statistics show that women have a greater participation rate in religious organisations than men. Women are more likely to express a greater interest in religion, to have a stronger personal faith and believe in life after death. They are more likely to involve themselves in religious rituals and worship, for example, attend religious services and lead a more religious life generally. There are many sociological explanations as to why women are more religious than men. Firstly, Miller and Hoffmann suggest that gender socialization means females are brought up to be more compliant, obedient and nurturing than males. They state that women are more involved with feelings, co-operation and caring for others. However, Walter and Davie see women as more exposed than men, to the ups and downs and changes of life. This is because of their biological involvement through childbirth, and through their greater participation in paid caring jobs, for example as teachers, nurses, social workers. Davie suggests that these factors give women a closer association with birth and death than men, and these are also central issues for many religions. They make women more aware of the helplessness of human life, and more familiar to the spiritual dimensions for human existence. Women are also more likely to turn to religion as a result of feeling deprived; they are more likely to experience poverty, family problems, less self confidence and less power. This means they turn to religion for comfort, particularly in religious sects and new religious movements which provide theodicies explaining their feelings, as well as solutions and support. Status frustration may be experienced by some women, who lack personal fulfilment or status as a result of being restricted to the home by the constraints of housework and childcare, or are in unsatisfying lower-middle-class jobs, which are mainly done by women. Religious participation, particularly in religious sects or new age cults, may help to overcome or compensate for this. Due to women staying at home for child care or having part time jobs, some would argue that this allows women to have far more spare time to be able to attend religious groups, therefore increasing their attendance. Statistics show women’s attendance to religious organisations are higher than men’s, however some Marxist  feminists such as Bevoir and Bird argue that religion is used to oppress women. The view that religion has negative consequences for women is conveyed in the study by Bevoir, who sees religion as patriarchal and oppressive. She supports the Marxist perspective and suggests that religion is oppressive and serves to control and reimburse the second class status given to woman. Which is similar to Marx’s viewpoint on the polerteriants who believe religion gives women a false belief that they will be compensated for their suffering on earth by equality in heaven. This argument suggests that religion is patriarchal therefore it is inevitable that it will end up having negative consequences for women. According to feminists there are countless example of patriarchy which have been used to control and later oppress women. Places of worship show this as they often segregate the sexes. An example of this is the Jewish synagogue in which women are placed behind screens separate from the men who in turn are situated in the main centre space. This highlights the marginalisation between the men and women. Although there are some rising female readers of religion, scriptures were first and foremost written and interpreted by men and it is men that are the head of the churches in Islam and Catholicism. This could mean that many values and ideologies such as wearing the Burka, beatings, female circumcision and bans on contraception may have been misinterpreted for men’s gain and passed on through generation to generation. May religious women are still not permitted to become priests or are only allowed to work themselves up to a certain level before they hit a religious ‘glass ceiling’, identifying where they want to be, but not being able to reach it due to the constraints set upon them. On the other hand, there are views to suggest that women are no longer oppressed in religion. For example, many cults are run by women and Paganism, from which many New Age religions originate, remains the most female-friendly approach to religion with a strong feminist element, where God is a mixture of male and female, and strong female leadership is common. Individuals seem to develop a greater attachment to religion as they grown older. Religious belief is lowest among those under 34, and highest among those over age 55. Young people are not only less likely to participate in mainstream religious activity than older people; more than half of them say they don’t regard themselves as religious at all, as shown in such studies as the British  Social Attitudes survey and the European Values study. There are three main reasons as to why older people might be more religious than the younger generation. The first being disengagement. This means that as people get older, they become detached from integrating mechanisms of society, such as participation in workplaces through paid employment. Older people may face increasing social isolation as partners and friends die. Participation in religious organisations provides a form of social support in this situation, and a network of people to relate to. The second is religious socialization, where older people are more likely to have a greater emphasis places on religion through the education system and socialization in the family when they were younger. Lastly, ill health and death. Older people tend to be faced with declining health, and death looms on the horizon. These are the very things that religion concerns its self with. The aging process and disengagement from society may therefore generate an engagement with religion for comfort, coping, meaning and support. Young people are less religious in terms of their expressed religious belief in surveys and their participation in mainstream religions, however this may be because these are simply being expressed in new, private ways which are difficult to record in surveys. Lynch suggests that young people may be running away from conventional ideas of religion as they can now go ‘spiritual shopping’. This involves an increasing exposure and accessibility to a diversity range of religious and spiritual ideas. This has encouraged new ways of exploring religion and spirituality. Young people may be choosing to take of their religion, of whatever faith or mix of beliefs, as a private matter. Davie expressed this in the words ‘believing without belonging’. This is where individuals may have a belief in something, however they do not chose to practice this belief. Secular spirituality and the sacred, Lynch suggested that young people may not have lost all religiosity , but that is simply finding new forms, many of which are associated more with the secular and non-religious world than with religious as it is currently understood by most people. Pragmatic reasons also mean there are a range of possible more practical or pragmatic explanations for the decline of religious belief and commitment amongst young individuals. Leisure activities have become a much bigger part of life, and shops and pubs all open for very long hours, including Sundays. Young people have more demands on their time and they may  simply have more interesting ad enjoyable things to do.

Human resource management Essay

To establish the role of Performance Management in controlling and developing employees it is imperative to understand the definition of Performance Management and its evolution. Evolution Performance Management is relatively a new concept, which has developed tremendously since the last two decades. As per CIPD (2009) Performance Management has been around in the language of HR and people management since the 1980’s. The above point is also mentioned by Williams R, (1998) stating that Performance Management came into prominence in the late 1980s/ early  1990s. â€Å"The term performance management was first used in the 1970’s but it did not become a recognised process until the latter half of 1980s† (Armstrong, 2009). Thorpe, (2004) states that ‘Performance management as an identifiable subject for academic study and research arguably began in the mid-1990’s’ Performance Management has evolved over the years from performance appraisal systems into a more holistic approach. As per Bach, (2005) â€Å"With the increased recognition of the problems that permeate many company appraisal schemes, there has been a shift of emphasis from performance appraisal to performance management† (p290). â€Å"The reality of contemporary performance management practice is probably best seen as ‘a logical progression in the history of the development of appraisal systems’† (Lundy and Cowling, 1996, p307). Definitions ‘The essence of Performance management is establishing a framework in which performance by human resources can be directed, monitored, motivated and refined; and the links in the cycle can be audited’ (Clark, 2005) As per Armstrong and Barron, (2009) Performance management is ‘A process which contributes to the effective management of individuals and teams in order to achieve high levels of organisational performance’ (cited in CIPD 2012). ‘Performance management encompasses activities such as joint goal-setting, continuous progress review and frequent communication, feedback and coaching for improved performance, implementation of employee-development programs and rewarding achievements. It can be regarded as a systematic process by which the overall performance of an organisation can be improved by improving the performance of individuals within a team framework’ (Drum, 2005) ‘Performance management is the process of creating a work environment in which people can perform to the best of their abilities. It is a whole work system that begins when a job is defined as needed and expectations are clearly communicated to the employee’ (Den Hartlog et al. , 2004) The role of Performance Management in both controlling and developing employees: Beamon, 1999, argues that, ‘Despite the increasing focus on collaboration between enterprises from one side, existing studies in the area of performance management still narrowly look at the single enterprise and its â€Å"within-enterprise† process and people ‘(cited in Busi and Bititci, 2006). The literature review brings up some interesting common themes and issues that run through the existing literature, research and definitions of performance management. These common themes will focus on features of performance management and its application in an organisation. Performance Management versus Performance Appraisal Although Performance Management evolved from performance appraisals few decades ago, most literature still intensely focuses on performance appraisals when addressing performance management. CIPD (2012) ‘While performance appraisal is an important part of performance management, in itself it is not performance management: rather, it is one of the range of tools that can be used to manage performance. However, it is a common mistake to assume that if organizations implement performance appraisals, they have performance management. Performance management is a holistic process bringing together many activities that collectively contribute to the effective management of individuals and teams in order to achieve high levels of organizational performance. The process is strategic, in that it is about broader issues and long-term goals, and integrated in that it links various aspects of the business, people management, individuals and teams. Performance appraisal on the other hand is operational, short- to medium-term and concerned only with individual employees and their performance and development. While it is one of the tools of performance management, and the data produced can feed into other elements of performance management, appraisal by itself does not constitute performance management’. Bach (2009) also states the difference between performance management and performance appraisal, ‘Advocates of performance management claim that its value resides in the cycle of integrated activities, which ensure that a systematic link is established between the contribution of each employee and the overall performance of the organisation. This strategic approach contrasts with the free standing nature of performance appraisals, in which the outcomes of each individual appraisal are rarely linked to overall corporate objectives’ (p291). However, CIPD (2005) Survey report demonstrates that, the practice of performance management still largely revolves around objective setting and appraisal. The confusion and overlapping in organizations between performance appraisals and performance management is evident form the above literature and surveys, however it still acts as a good tool for managers to control and develop employees. Performance management is a cycle, an on-going process Performance management is a cycle and for it to deliver desired results, it needs to be an on-going process. Conventionally, Performance management is portrayed as a three-stage cycle involving performance planning, monitoring and review (Armstrong and baron, 2005) The Performance management cycle CIPD (2012) also states ‘Performance management is a process, not an event, it operates as a continuous cycle’. Clark (2005) in his definition of Performance management also refers performance management as a cycle ‘The essence of Performance management is establishing a framework in which performance by human resources can be directed, monitored, motivated and refined; and the links in the cycle can be audited’. CIPD Discussion paper (2009) mentions that using a survey and a number of practice-based case studies, this work concluded that performance management was most likely to be viewed as a continuous process rather than an annual activity. Porter et al (2012) states that, ‘Performance management is not an independent activity; it is in fact a series of processes supporting different elements of effective people management. Performance therefore needs to be placed very firmly in a management context’ (p 140).
