Accuracy of Rectal Water Contrast Transvaginal Ultrasound
Accuracy of Rectal Water Contrast Transvaginal Ultrasound Abstract Objectives:à To compare the accuracy of rectal water contrast transvaginal ultrasound (RWC-TVS) and double-contrast barium enema (DCBE) in assessing the presence and extent of bowel endometriosis. Methods:à This prospective study included 198 patients of reproductive age with suspicion of bowel endometriosis. RWC-TVS and DCBE were performed before operative laparoscopy by two groups of physicians specialized in endometriosis, each blinded to the results of the other groups. Findings of RWC-TVS and DCBE were compared with histological results. The severity of pain experienced during RWC-TVS and DCBE was measured by a 10 cm visual analog scale. Results:à In total, 110 of the 198 women had bowel endometriosis nodules confirmed at laparoscopy and histopathology patients. For the diagnosis of bowel endometriosis DCBE and RWC-TVS had a sensitivity of 96.4% and 88.2%, specificity of 100% and 97.3%, positive predictive value of 100% and 98.0%, negative predictive value of 98.0% and 88.0% and accuracy of 98.0% and 92.4% respectively. DCBE was associated with more intense pain than was RWC-TVS. Conclusions: RWC-TVS and DCBE have similar accuracy in the diagnosis of bowel endometriosis, but patients tolerate RWC-TVS better than they do DCBE. Keywords: double-contrast barium enema; rectal water contrast transvaginal ultrasound; bowel endometriosis; diagnosis Introduction Bowel endometriosis affects between 4-37% of patients with endometriosis1. Intestinal endometriosis lesions may have variable size2. Small endometriosis nodules located on the serosal surface of the bowel rarely cause symptoms and, therefore, do not require treatment2. Larger endometriosis nodules infiltrate the bowel wall and may cause various gastrointestinal complaints such as dyschezia, diarrhea, constipation, abdominal bloating and intestinal cramping1, 3. These symptoms may mimic irritable bowel syndrome. Symptoms caused by bowel endometriosis are nonspecific, often resulting in misdiagnosis or delay in diagnosis4. Physical examination may suggest the presence of rectovaginal endometriosis; however, it has poor accuracy in diagnosing rectosigmoid nodules5, 6. Until recently, the ultrasonic diagnosis of endometriosis was limited to patients with ovarian endometriomas and other imaging techniques were used for the assessment of bowel endometriosis including rectal endoscopic ultrasound, transvaginal ultrasound (TVS), double-contrast barium enema (DCBE), magnetic resonance imaging (MRI), multidetector computerized tomography enema (MDCT-e) and virtual colonoscopy7-10. TVS is a reliable non-invasive method to assess the presence and the extent of bowel endometriosis11. Injecting saline through a catheter into the rectum during TVS (rectal-water contrast TVS, RWC-TVS) may facilitate the identification of rectosigmoid nodules, the assessment of the depth of infiltration of endometriosis in the intestinal wall and estimation of the degree of stenosis of the bowel lumen. However, no previous study compared the accuracy of DCBE and RWC-TVS in the diagnosis of rectosigmoid endometriosis4, 12, 13. A preoperative diagnosis of the presence and extent of bowel endometriosis is necessary to determine whether surgery is required and to plan the surgical procedure with the colorectal surgeon14. Knowing before surgery the size and number of intestinal endometriosis nodules, the depth of infiltration of the nodules in the intestinal wall and the degree of stenosis of the bowel lumen allows determining whether surgery is required and may allow the surgeons to choose between nodulectomy and bowel segmental resection15, 16. In addition, determining before surgery the extent of bowel endometriosis allows the surgeon to inform the patient about the potential benefits and complications of the surgical procedure that will be performed. In fact, postoperative complications and evolution of digestive symptoms after surgery may differ between patients undergoing nodulectomy and those undergoing segmental resection, with a higher incidence of bladder-voiding dysfunction and postoperative constipation in patients undergoing the latter procedure. In this study, we compared the accuracy of DCBE and RWC-TVS in assessing the presence and extent of bowel endometriosis. Methods Study population This prospective study was performed between May 2012 and Aug 2016. Participants were recruited among patients of reproductive age scheduled for laparoscopy with strong suspicion of intestinal endometriosis based on symptoms and clinical examination. During this period, the imaging workup required that both DCBE and RWC-TVS were performed in patients with suspicion of bowel endometriosis. Institutional review board approval was obtained before initiating the study. Patients participating in the study signed a written consent form. Inclusion criteria for the study were: reproductive age and suspicion of deep pelvic endometriosis; presence of gastrointestinal symptoms that might be caused by bowel endometriosis; and desire to undergo complete surgical excision of the endometriosis. Patients were excluded from the study if they had previous bilateral ovariectomy; previous barium radiological examination or radiological diagnosis of bowel endometriosis; previous colorectal surgery; previ ous episodes suggestive of intolerance to iodinated contrast medium; renal or hepatic failure; refusal to undergo DCBE and psychiatric disorders. Symptoms were systematically investigated during the study period and they were recorded in a database. The presence of dysmenorrheal, deep dyspareunia, non-menstrual pelvic pain and dyschezia was investigated and the intensity of their symptoms was assessed in all patients on a 10 cm visual analog scale (VAS), on which the left extremity represented absence of pain and the right extremity indicated maximum intensity of pain. The presence of the following gastrointestinal symptoms was assessed: diarrhea-predominant irritable bowel syndrome; constipation-predominant irritable bowel syndrome; passage of mucus in the stools; rectal bleeding; intestinal cramping; and abdominal bloating. A symptom analogue scale questionnaire was used to estimate the severity of each gastrointestinal symptom. DCBE and RWC-TVS results were compared with surgical and pathologic findings. The radiologists performing DCBE and the gynecologists performing TVS were each blinded to the others results. They were blinded to the clinical data and knew only that the presence of intestinal endometriosis was suspected. All patients underwent laparoscopy within 1 month from the completion of the diagnostic investigations. Intestinal endometriosis was defined as the disease infiltrating at least the muscularis propria. Endometriosis foci located on the bowel serosa were considered peritoneal and not bowel endometriosis. The present study determined the accuracy of DCBE and RWC-TVS in assessing the presence of bowel endometriosis, estimating the size and the number of bowel endometriosis nodules and determining the presence of peritoneal endometriosis infiltrating only the intestinal serosa. Rectal water contrast transvaginal ultrasound technique Two physicians performed all the examinations according to a standardized procedure. RWC-TVS was performed by using a Voluson E6 machine connected to a transvaginal transducer. After the transducer had been introduced into the vagina, an assistant inserted a 6-mm flexible catheter through the anus into the rectal lumen up to a 15 cm distance from the anus. A gel infused with lidocaine was used to facilitate passage of the catheter. A 50 mL syringe was connected to the catheter and warm sterile saline solution was injected inside the rectum and the sigmoid under ultrasonic control. The amount of saline solution needed to show the rectosigmoid ranged between 100 and 350 mL, depending on the distensibility of the intestinal wall. One hundred milliliters of saline solution were continuously and slowly infused at the beginning of the procedure; the rest of the solution was infused when requested by the ultrasound. During ultrasound, when saline solution was not being infused, backflow through the catheter was prevented by placing a Klemmer forceps on the catheter. There w as no significant leakage of saline solution into the space between the catheter and the anus. Images were obtained before, during and after saline injection. Bowel endometriosis appears ultrasonographically as a nodular, solid, hypoechoic lesion, adjacent to and/or penetrating the intestinal wall. Hyperechoic foci may sometimes be present within the lesion. Intestinal distension allows defining the limits of the intestinal nodules and in particular the various layers of the rectal wall in order to estimate the depth of infiltration. The intestinal serosa is hyperechoic; the two layers of the muscularis propria appear as hypoechoic strips separated by a fine hyperechoic line; the submucosa is hyperechoic; the muscularis mucosa is hypoechoic and the interface between the lumen and the mucosal layer is hyperechoic. Rectal endometriosis infiltration is demonstrated by the fact that the hypoechoic nodule penetrates the intestinal wall and, in general, it thickens the muscularis mucosa. Two different ultrasonic signs are commonly used to describe this condition. Double-contrast barium enema All DCBE procedures were carried out using a motorized tilting table for fluoroscopic and radiological examination. In preparation, patients maintained a low-residue diet for 1 day prior to the examination in order to keep the enteric content fluid. The examination was performed after intramuscular administration of 20 mg (1 ampoule) Scopolamine in order to induce colonic hypotonia. The presence of bowel endometriosis was diagnosed on DCBE when the bowel lumen was narrowed at any level from the sigmoid to the anus in association with crenulation of the mucosa and/or speculation of contour. Tolerability of the examinations Immediately after each examination patients were asked to rate the discomfort encountered during DCBE and RWC-TVS by means of a 10 cm visual analogue scale (VAS), mild pain was defined as a VAS score of 5. Surgery and histological evaluation The surgeons examined the reports and the images of DCBE and RWC-TVS prior to laparoscopy. Although the diagnosis of recto-sigmoid endometriosis and its treatment were based on laparoscopic findings. All surgical procedures were performed laparoscope by a team of gynecological and colorectal surgeons with extensive experience in the treatment of pelvic and bowel endometriosis. In all cases, after adequate adhesiolysis, the sigmoid colon and rectum were systematically examined to verify the presence of endometriosis lesions. Bowel endometriosis lesions were removed by intestinal resection in cases of a single lesion >3 cm in diameter, a single lesion infiltrating at least 50% of the circumference of the intestinal wall or three or more lesions infiltrating the muscular layer. In all other cases of bowel endometriosis partial- or full-thickness disk resection was performed. Intestinal lesions infiltrating only the serosal layer of the bowel wall were excised by shaving. All visible les ions suspected to be endometriosis were excised and sent for histological examination in agreement with our clinical protocol. The surgical specimens were evaluated by histological; the depth of infiltration of the endometriosis nodules in the bowel wall was assessed. In cases of nodulectomy the specimens were macroscopically oriented along the intestinal wall (from the serosa towards the mucosa) and cut into macro sections of 2 mm thickness. From each macrosection tissue blocks of 1.5 cm length were obtained in variable numbers according to the size of the lesion, and from each tissue block a 5 à µm section was obtained for microscopically evaluation. In cases of bowel resection the specimen was opened longitudinally through its entire length and 2mm longitudinal bands of bowel wall, reaching the two resection margins and passing through all macroscopically visible lesions, were cut. These bands were sampled in tissue blocks and 5 à µm sections were obtained for microscopic evaluation. Statistical analysis Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were calculated for both DCBE and RWC-TVS. The diagnostic value of each test was also assessed using positive likelihood ratio (LR+) and negative likelihood ratio (LR-). Efficacy parameters were calculated with 95% confidence intervals (CIs). McNemars test with the Yates continuity correction was used to compare the accuracy of DCBE and RWC-TVS in the diagnosis of intestinal endometriosis. McNemars test was used to compare the number of patients in which the number of rectosigmoid nodules was correctly identified by DCBE and RWC-TVS. The accuracy of the measurement of nodule size by imaging techniques was estimated by subtracting the size of the nodule as measured by the techniques from the size of the nodules measured at histology. The nonparametric Mann-Whitney test was used to compare the intensity of pain experienced by patients during DCBE and RWC-TVS, the chi-square test was used to co mpare the type of pain (mild, moderate or severe) and Spearmans rank correlation coefficient was used to determine whether there was a correlation between the intensity of pain experienced by patients during the two techniques. Data were analyzed using the SPSS software. p Results Study population A total of 198 patients were enrolled in the study and all underwent surgery were included in this study (Figure 1). The main demographic characteristics of the study are demonstrated in Table 1. The intensity of pain and gastrointestinal symptoms are presented in Table 2. Surgery and histology demonstrated that 110 patients (55.6%) had bowel endometriosis nodules. The endometriosis lesions infiltrating the intestinal serosa in 28 patients. The remaining 82 patients had only pelvic endometriosis with no evidence of intestinal lesions. The largest intestinal endometriosis nodule was found locate on the sigmoid colon in 53 patients, on the rectum in 30 patients, at the rectosigmoid junction in 20 patients, on the ileum in 5 patients and on the caecum in 2 patients. The endometriosis lesions infiltrating only the intestinal serosa were located on the sigmoid colon in 15 cases, on the rectum in 5cases and at the rectosigmoid junction in 3 cases. The mean (à ±SD) length of the resected bowel segment was 12.2 à ± 3.6 cm. The diagnosis of endometriosis was confirmed in all the excised nodules by histological exam. Furthermore, it demonstrated that the deepest endometriosis nodule infiltrated the muscularis propria in 62 patients (56.4 %), the submucosa in 3 1 patients (28.2%) and the mucosa in 17 patients (15.5%). Accuracy of RWC-TVS and DCBE in the diagnosis of bowel endometriosis The accuracy, sensitivity, specificity, PPV, NPV, LR+ and LR- of DCBE and RWC-TVS in the diagnosis of bowel endometriosis are described in Table 3. DCBE identified 106 of 110 patients with bowel endometriosis (96.4%). In 4 patients endometriosis nodules infiltrating the muscularis propria of the rectum were not identified, which were excised by partial-thickness nodulectomy. RWC-TVS identified 97 of 110 patients with intestinal endometriosis (88.2%). RWC-TVS did not identify 4 ileal lesions, 2 cecal lesions, 4 sigmoid nodules and 3 rectal nodules infiltrating the muscularis propria. Furthermore, we identified 4 of these patients had large bilateral endometriosis ovarian cysts, which may have hampered the identification of intestinal nodules. There was 2 false positive on RWC-TVS-a rectovaginal endometriosis nodule that was judged to infiltrate the muscularis of the rectum. Surgery confirmed the presence of the rectovaginal nodule but did not reveal infiltration of the rectal muscularis. The sensitivity, specificity, PPV, NPV, LR+, LR- and accuracy of the two techniques in the diagnosis of intestinal endometriosis were shown in Table 3. McNemars test showed that there was no significant difference in the accuracy of the two techniques in the diagnosis of bowel endometriosis (P=0.109). Histology examination demonstrated that endometriosis infiltrated the submucosa or mucosa of the rectosigmoid colon in 53 patients. DCBE correctly identified the depth of infiltration in 27 of these patients (50.9%), while RWC-TVS correctly identified the depth of infiltration in 20 of them (37.7%) (P=0.126). All the other nodules that were seen to infiltrate the submucosa or mucosa at histology were judged to reach only the muscularis at DCBE and RWC-TVS. Both techniques had no cases of false-positive diagnosis of submucosal or mucosal infiltration. Both DCBE and RWC-TVS underestimated the size of the endometriosis nodules; however, the underestimation was greater for RWC-TVS than for DCBE (Table 4). In addition, in both imaging techniques the underestimation was greater for nodules with diameterâⰠ¥30 mm. Tolerability of DCBE and RWC-TVS DCBE was safely performed in all the patients. During both the examinations all patients tolerated intestinal distension and in no patient was it necessary to interrupt the procedure. However, the intensity of pain experienced during DCBE was significantly higher than the intensity of pain experienced during RWC-TVS (Table 5). A positive correlation was observed between the intensity of pain experienced by the patients during the two examinations (Spearman correlation coefficient=0.575; p Discussion To the best of our knowledge, this is the first study demonstrated that DCBE and RWC-TVS have similar accuracy in the diagnosis of bowel endometriosis. Both RWC-TVS and DCBE underestimated the size of bowel endometriosis nodules, but under estimation was greater for RWC-TVS than for DCBE, particularly when the nodules had largest diameter âⰠ¥ 30 mm (Table 4). The choice of the ultrasonic technique is often based on the experience of the ultrasonographers rather than on evidence of superiority of one technique compared to the others. In fact, TVS must be performed by highly skilled, it has been recently estimated that the learning curve for an accurate diagnosis of deep pelvic endometriosis by TVS requires performing about 40 cases17. Therefore, it may be difficult to achieve such experience for ultrasonographers working in small hospital. The main advantage of DCBE could be that, with a retrograde distension of the entire colon, this technique may provide a complete overview of t he whole colon18. In the current study, the distension was targeted to the rectosigmoid because the aim of the study was the comparison with RWC-TVS and endometriosis lesions of the right colon are beyond the field of view of a transvaginal approach. Furthermore, we did not compare the accuracy of RWC-TVS with TVS alone, which was the objective of a previous study. RWC-TVS was chosen for the comparison with DCBE because of the personal experience of the authors and of the common criterion of bowel distension with fluid. The usefulness of this technique was subsequently confirmed by the same authors in larger series. Furthermore, other authors confirmed that intestinal distension and opacification using ultrasound gel helps to visualize rectosigmoid endometriosis nodules19, 20. Previous studies have suggested that TVS could reliably diagnose rectosigmoid endometriosis. The sensitivity of TVS for detecting rectosigmoid endometriosis is between 91 and 98%, the specificity between 97 and 100%, the PPV between 97 and 100% and the NPV between 87 and 98%21-24. Recently, RWC-TVS has been developed to facilitate identification of intestinal lesions in patients with rectovaginal endometriosis and to determine the depth of infiltration of endometriosis in the intestinal wall25. TVS has been extensively used in patients with bowel endometriosis; while only little data is available on the use of DCBE in these patients. This study demonstrated that DCBE and RWC-TVS have similar accuracy in the diagnosis of bowel endometriosis. Both techniques precisely estimated the length of the rectosigmoid nodules, but DCBE was more precise than RWC-TVS in assessing the distance between the endometriosis nodule and the anal verge9. Obviously, the extensive experience of the radiologi st and the gynecologist in DCBE and RWCTVS, respectively, may have influenced the accuracy of these techniques in diagnosing bowel endometriosis24, 26. The findings may be explained by the fact that when performing imaging techniques, particularly RWC-TVS, it might be difficult to choose the plane in which the irregular endometriosis nodule has the largest diameter. However, the difference between the estimated size of the nodule and the largest diameter as measured on histopathology was quite small and, in most cases, it seems unlikely that this difference would affect the choice of nodulectomy or bowel resection as treatment27. Importantly, patients tolerated RWC-TVS better than they did DCBE. These findings are in line with those of previous studies demonstrating the accuracy of TVS in the diagnosis of bowel endometriosis and comparing TVS with other techniques such as MRI and rectal endoscopic ultrasound11, 28-30. The potential benefits of introducing aqueous contrast medium into the rectum during TVS have been questioned. TVS is an operator-dependent procedure and it is possible that the differences observed in the accuracy of this technique are determined by the experience of the ultrasonographer carrying out the procedure31. However, adding intestinal aqueous contrast to TVS may facilitate the identification of rectosigmoid lesions. Other techniques have been proposed for improving the accuracy of TVS in the detection of deep endometriosis, such as sonovaginography or the use of large quantities of ultrasound transmission gel (12 mL) in the probe cover32. Up to now, no study has established whether any one of these ultrasonic techniques is superior to the others in the diagnosis of deep endometriosis. TVS should be considered the first-line investigation in patients with deep endometriosis, and allows the diagnosis of intestinal lesions24. Other investigations such as RWC-TVS, MDCT-e, MRI, rectal endoscopic ultrasound and DCBE may be used to determine the characteristics of intestinal endometriosis, such as the size and number of nodules, the depth of infiltration of the nodules in the intestinal wall and the degree of stenosis of the bowel lumen33-35. RWC-TVS has several advantages over the other techniques. It is less expensive than MDCT-e and MRI and the equipment required to perform the procedure is commonly available to gynecologists, who are usually involved in the management of patients with endometriosis. A recent study has shown that RWC-TVS allows estimation of the degree of stenosis of the intestinal lumen caused by endometriosis36. Unfortunately, this parameter was not examined in the current study- the major limitation of our investigation. Theoretically, RWC-TVS may also allow determination of the extent of the disease along the longitudinal intestinal axis. Obviously, RWC-TVS cannot determine the presence of intestinal nodules located proximally to the sigmoid because these lesions are beyond the field of TVS. This study had several limitations. First, the experience of the ultrasonographer in RWC-TVS may influence the accuracy of these techniques in diagnosing bowel endometriosis. Second, the surgeons were aware of the findings of DCBE and RWC-TVS. Although in an ideal prospective study the surgeons should be blinded to the findings of the preoperative investigations, this theoretical study design appears unethical in clinical practice because diagnostic imaging may facilitate the identification of intestinal endometriosis nodules during surgery. Furthermore, the knowledge of the findings of the preoperative investigations may only help the surgeons in identifying endometriosis nodules that were actually present. Third, RWC-TVS and DCBE did not estimate the percentage of the circumference of the intestinal wall infiltrated by endometriosis, a criterion used to choose between nodulectomy and bowel resection. Therefore, patients scheduled for nodulectomy on the basis of DCBE and RWC-TVS fin dings should be informed that bowel resection might be required for the complete excision of intestinal endometriosis. Future studies should examine whether DCBE and RWC-TVS can reliably estimate what percentage of intestinal circumference is infiltrated by endometriosis. DCBE may still have a role in the diagnostic workup of patients with suspected bowel endometriosis. When TVS or RWC-TVS demonstrates large intestinal nodules infiltrating the bowel muscularis, bowel resection can probably be performed without further investigation unless the surgeon wants to exclude intestinal lesions located proximally to the sigmoid. In contrast, when ultrasound demonstrates a single bowel nodule that may be excised by nodulectomy, DCBE should be used to exclude the presence of other intestinal nodules and, thus, to adequately plan the surgical procedure with the colorectal surgeon and the patient. Conclusions This study showed that RWC-TVS is a reliable technique for determining the presence and extent of bowel endometriosis and that it has an accuracy similar to that of DCBE. However, RWC-TVS may sometimes underestimate the presence of multiple bowel nodules and can be performed easily in an ambulatory setting and it is better tolerated by patients. It may be hypothesized to combine TVS and DCBE to achieve a complete preoperative assessment of the bowel in order to offer to the patients an adequate counseling and the most appropriate one-step surgical treatment.

The Success of Thomas Hardys Novel The Return of the Native as a Trage
The Success of Thomas Hardy's Novel The Return of the Native as a Tragedy On the first chapter of this novel Egdon Heath is presented as an untameable force "unmoved during so many centuries, through the crisis of so many things, that it could only be imagined to await one last crisis - the final overthrow". Thus, from the very beginning of the novel we can expect an outcome of tragic possibilities. Similarly to ancient Greek tragedies, the action in "The Return of the Native" takes place during a restricted period of time. Usually, in Greek tragedies the plot developed within 24 hours, while Hardy limits himself to the space of 5 books, which represents an exact time of 1 year and a day. Although the novel extends to a 6th book; the main action and the tragedy itself is developed within the first five books. As its title indicates, the sixth book, "Aftercourses" was added to please the readers of the magazine in which his novel was published, in order to put a more closed end to the series. He provided them with a happy ending; as Thomasin and Venn end up marred. However, in its 1912 edition, Hardy included a footnote at the end of the book in which he stated that it was left to the reader to choose whichever ending he/she preferred. Ironically, Hardy declared "à ¢Ã¢â ¬Ã ¦and those with an austere artistic code can assume the more consistent conclusion to be the true one". By this, Hardy suggests that the real appraisers of tragedy would conclude on the tragic ending as the most fitting; consistency being also considered by Aristotle as an essential element for tragedy. As a result, similar also to Shakespearian tragedies, which were divided into five acts, the action in Hardy's novel is set up in the first... ... of place, time and other tragedy conventions; the way the plot develops with a sense of foreboding in the novel's consequences, convert this book into a classic of the genre. The relentless mood and development, the numerous lucky (or unlucky) coincidences that are later to determine the future of the characters and the way people continually strive to change the way things are, combine the prefect ingredients of a tragedy. As often in Greek tragedies, fate plays an essential role and the people in the novel can't escape it because it would only keep coming back. Chance seems to dictate the destiny of the characters, playing around with their lives as if they were mere pieces on a chess board. The forces of the heath seem to inflict some sort of control on the characters, fulfilling the Greek tragedy convention of gods playing around with humans' lives.

Precocious Puberty
The difference between Precocious Puberty and puberty itself is Precocious Puberty is normally found in children between the ages 8 and 11. While puberty normally does not hit children till around age 11-14. The Mayo Clinic best describes Precocious Puberty as: ââ¬Å"Precocious Puberty is when the body changes from that of a child into an adult. It includes rapid growth of bones, teeth and muscles; changes in body shape and size; and development of the body's ability to reproduce. Precocious Puberty normally begins in girls between ages 8 and 12 and in boys between ages 9 and 14.The cause of precocious puberty often cannot be found. â⬠Rarely, conditions such as infections, hormone disorders, tumors, brain abnormalities or injuries may cause precocious puberty. Treatment for precocious puberty typically includes medication to delay further development. There are 5 different types of Precocious Puberty. Gonadotropin-dependent precocious puberty is very common and affects mostly girls and half of the boys. This is a disorder which is triggered by premature secretion of puberty controlling hormones or higher levels of gonadotropins.Gonadotropin-independent precocious puberty mostly affects boys with low gonadotropin levels. Central precocious puberty is not triggered by any underlying reason. It is merely a body response to changes that concern the central nervous system. Isosexual precocious puberty causes the sign of femininity in girls and masculinity in boys. Heterosexual precocious puberty is just opposite of Isosexual precocious puberty which brings the sign of femininity in boys whereas masculinity in girls. Early onset of puberty can cause several problems.The early growth spurt initially can cause tall stature, but rapid bone maturation can cause linear growth to cease too early and can result in short adult stature. Most children, boys and girls alike that have Precocious Puberty end up being less than 5 feet tall. According to Kids Health (1995) t here are signs to be on the lookout for. For instance, ââ¬Å"in girls the telltale signs of precocious puberty include any of the following before 7 or 8 years of age include: breast development, pubic or underarm hair development, rapid height growth, and onset of menstruation.In boys, the signs of precocious puberty before 9 years of age include: enlargement of the testicles or penis, pubic, underarm, or facial hair development, rapid height growth ââ¬â a growth ââ¬Å"spurtâ⬠, and voice deepening. â⬠Both girls and boys will have an onset of acne and adult mature body odor. An 8 year old child having such things causes problems for that child. Itââ¬â¢s always difficult to be different, and maturing into an adult-looking body earlier than your peers puts a lot of pressure on children. A child I know, Roberta, is only 7 years old and has Central Precocious Puberty.The mental affects it has on Roberta is outrageous; she is a second grader having to deal with wearin g sanitary napkins, the ââ¬Å"smellâ⬠associated with periods, the self-image problems of already growing breast, among many more issues. This can really wear on a child, especially one that is so young. Roberta is finding it hard to maintain her friends, once they find out about her already having periods their momââ¬â¢s want them to not be friends anymore. One little girl had been friends with Roberta since Preschool then the mom found out that Roberta was wearing sanitary napkins and told her daughter she could not be friends with Roberta anymore.Robertaââ¬â¢s mom went to talk to this lady, and her response was, she was not ready to have ââ¬Å"the talkâ⬠with her daughter yet. It was better they not be friends to prevent Roberta from telling her daughter anything. It is more difficult for girls than boys. Girls have undeniable signs that are visible to everyone. Boys can hide their growing penis and chest hair from their friends, the only thing they cannot hide is their facial hair if that is coming in early. Both boys and girls can have a tough time when they go through pubertal changes.Children who go through the changes at the age of 8-11 while their friends do not hit puberty till 11-14, makes it even harder for those early bloomers to cope. Children with Precocious Puberty may be stressed because of physical and hormonal changes; they are just too young to understand all the changes their body is making. These children will be teased and may end up having body image or self-esteem problems. Girls who reach menarche before age 9-10 may become withdrawn and may have difficulty adjusting to wearing and changing sanitary napkins.Roberta has had problems adjusting to wearing the sanitary napkins and she wants to make sure no one can see them from her pants. It is very confusing and traumatizing for her. Both sexes, boys more often than girls, may have increases in libido leading to increased masturbation or inappropriate sexual behaviors a t a young age. Girls with a history of early puberty have a slightly earlier age of initiation of sexual activity. Some girls with Precocious Puberty enter the dating scene much earlier than their classmates.Early-maturing girls may also have behavior problems and a greater risk for substance abuse and suicide. The best thing for the children struggling through precocious puberty is for someone to be there for them, listen to them, encourage them, let them know there are others who are just like them, and what they are going through is normal. It may not normal for their age, but normal none the less. All children go through adolescences. Those with Precocious Puberty are just going through adolescences sooner. In order to diagnose Precocious Puberty the doctor will perform a work up on the child.The doctor normally begins by reviewing the medical history of the family, doing a physical exam, reviewing blood work to measure hormone levels, and taking x-rays of the childââ¬â¢s han d and wrist to determine bone age. When diagnosing a child with Precocious Puberty, a doctor will look at the Tanner Stages to determine where the child is at. Tanner Stages is a system that was developed in 1969 it grew out of a two-decade-long study of girls as they transitioned through puberty. ââ¬Å"The Tanner staging system is named after Dr. James Tanner, who was a British pediatrician.He performed a longitudinal study in which the subjects were observed repeatedly over a period of time in the same context. â⬠(Dr. Greenspan 2006) In an experiment; the girls underwent examinations and photographs every three months. Dr. Tanner and his research group studied the progress and developed the 5 Tanner Stages that we use today. The Tanner Stages deal with both breast and genital development. Roberta (the afore mentioned child) has a Breast Tanner Stage 3 and a Pubic Hair Tanner Stage of 4; this happens more times than not for girls to be more advanced in one area over the othe r.She is biologically age 7 but her bone age is 11. Girls will have Tanner Stages numbered 1-5; childhood through adulthood. Boys will have only one Tanner Stage, Tanner Stages numbered 1-5; childhood through adulthood. According to the Mayo Clinic (1998) there is treatment for Precocious Puberty. The children can receive a treatment called Gn-RH analogue therapy, usually includes a monthly injection of a medication, such as leuprolide, which stops the HPG axis and delays further development. The child continues to receive this medication until he or she reaches the normal age of puberty.Once he or she stops receiving the medication, the process of puberty begins again. The goal of treatment for Precocious Puberty is to stop puberty from progressing so the child can have a normal healthy childhood. Treatment will also depend on the type of Precocious Puberty and the underlying cause, if known. According to Health of Children, there are several drugs that have been developed for trea tment: histerlin, nafarelin, synthetic gonadotropin-releasing hormone agonist, deslorelin, ethylamide, triptorelin, and leuprolide.If parents opt to have treatment, there is some after care that is required. The child will have follow up visits every 3-6 months to ensure that progression of puberty has been slowed or halted altogether. Normalization of accelerated growth, reduction in size of breasts and suppression of gonadotropin levels after receiving Gn-RH. Monitor bone age yearly to confirm that the rapid advancement seen in the untreated state has slowed typically to a half year of bone age per year or less.If parents opt to not have treatment, the child might need therapy to help with self-esteem issues, high anxiety, irritability or even withdrawal. Some studies have shown that not treating children has no effect on them at all with the exception to early adolescences. The best thing a parent can do is to discuss the ends and outs with the Endocrinologist about which treatme nt if any will be best for their child. Precocious Puberty is something a child can live with. Most importantly, there is help out there if they want it.

The Poverty Of The United States - 1204 Words
Maria V. Solis Sociology Henslin (2014) said ââ¬Å"Richard Rodriguez represents millions of immigrants ââ¬â not just those of Latino origin but those from other cultures, too-who want to integrate into U.S culture yet not betray their past. Fearing loss of their roots, they are caught between two cultures, each beckoning, each offering rich rewardsâ⬠There are many reasons of why people migrate to the United States. One of them is the poverty of the country that they live in. People who have children and see them having different needs and necessities go broken hearted because of not being able to afford many things kids need, some people donââ¬â¢t even have a home to live in or money to buy food.

Faye Hipsman, Doris Meissner (2013) said ââ¬Å"Today, the United States may be on the threshold of major new reforms that would address longstanding problems of illegal immigration, as well as those in the legal immigration system, which has not been updated since 1990. The impetus for comprehensive immigration reform (CIR) has returned to the congressional stage, with bipartisan groups in the House and Senate engaged in significant negotiations to craft legislation that would increase enforcement at the nation s borders and interiors, legalize the nationââ¬â¢s estimated 11 million unauthorized immigrants, and provide legal avenues for employers in the United States to access future workers they need. CIR, in one form or another, has been under consideration since at least 2001, with major debates in the Senate in 2006 and 2007. After the failure of CIR legislation in the Senate in 2007, the effort to reform the nation s immigration laws was sidelined. The results and voting patt erns of the 2012 presidential election gave both political parties new reasons to revisit an immigration reform agenda. Illegal immigration has
