Weight reduction led to resumption of ovulation and subsequent pregnancy antifungal oral medication best ketoconazole 200 mg, as well as a reduction of testosterone levels and increased sexhormone-binding globulin concentrations. Nevertheless, the management of obesity is difficult and requires a multidisciplinary approach. This would include modification of their dietary quality and change in physical activity. If this fails, pharmacotherapy ought to be considered and, ultimately, obesity surgery. If there is an underlying eating disorder, psychopathology should also be taken into consideration and appropriate referrals made. Pharmacotherapy includes two main groups of drugs: peripherally acting and centrally acting drugs. This medication inhibits gastric and pancreatic lipase and, therefore, reduces fat absorption from the intestine. Although it is generally well tolerated, it can cause gastrointestinal disturbances, which consequently lead to low patient compliance. The second category of drugs includes sibutramine, which inhibits serotonin and noradrenaline reuptake. It can cause a greater reduction in insulin levels and insulin resistance compared with metformin. As far as bariatric surgery is concerned, laparoscopic adjustable gastric banding remains the mainstream therapy. Nonetheless, further research is required in order to establish its role in improving fertility. After the procedure, contraception is required until the target weight is reached. It was speculated that by removing part of the hormone-producing ovarian tissue, androgen and inhibin levels would be reduced. Nevertheless, the response rate was variable and the procedure was abandoned largely because of the risk of postoperative adhesion formation. As soon as effective medical methods of ovulation became available, ovarian wedge resection became obsolete. Both laparoscopic ovarian cautery and laser vaporization (using carbon dioxide, argon or neodymium:yttrium aluminium garnet lasers) have been used since. The aim is to create approximately 10 holes per ovary in the ovarian surface and 243 17 Ovulation induction stroma. The mechanism of action is thought to be similar to that of ovarian wedge resection. In the literature, most data derive from randomized controlled trials comparing ovarian drilling with ovulation induction using exogenous gonadotrophins. Moreover, there was no evidence of a difference in clinical pregnancy rate, miscarriage rate, ovulation rate and quality of life. Its use is not recommended as an attempt to decrease the risk of developing diabetes mellitus or coronary artery disease. It is believed that the increased vascular permeability is the result of vasoactive agents released by the hyperstimulated ovaries. In more severe forms, ovaries become cystic and there is abdominal distention with pain, nausea, vomiting and diarrhoea. This may be followed by ascites, pleural effusion and, on rare occasions, pericardial effusions. There is marked intravascular volume depletion with haemoconcentration that may lead to severe manifestations, including thromboembolism, severe hypoalbuminaemia, hypovolaemia, oliguria and electrolyte disturbances. As the management of the condition will be dictated by its severity, it is mandatory to assess each case properly and classify it according to Table 17. It is a systemic disease resulting from vasoactive products released from hyperstimulated ovaries. Further research is required in order to evaluate their positive predictive value and possible future use. In the latter case, the couple should be advised to refrain from intercourse or to use barrier methods of contraception. A possible explanation could be that ovaries of younger women are more responsive to gonadotrophins, as they contain a higher number of gonadotrophin receptors and a larger number of follicles responding to gonadotrophins. A physical examination, including body weight, abdominal girth measurements, abdominal and cardiorespiratory examination, and assessment of hydration, must be performed. A pelvic ultrasound will help to assess the size of the ovaries and check for ascites. Blood tests should include full blood count, urea and electrolytes, liver function tests and clotting screen. If pericardial effusion is suspected, an electrocardiogram and echocardiogram will be essential. Non-steroidal anti-inflammatory drugs are contraindicated, as they may compromise renal function. In the case of haemoconcentration, more intensive hydration is needed; if the problem persists, colloid therapy needs to be considered.

Important late complications include failure to relieve presenting symptoms fungus lens cheap ketoconazole 200 mg buy on-line, infertility, pregnancy with associated complications and cancer. However, they are potentially serious and hence the surgeon must understand the working principles of the hysteroscopic equipment, including the energy source used, and undergo a structured training programme. Adequate explanation and consent improves patient satisfaction and decreases litigation when complications occur. The training process includes acquiring knowledge, working on laboratory models, attending a well-recognized structured course and assisting experts. Initial procedures are undertaken under general anaesthesia, followed by daycase procedures under local anaesthesia, and finally performing diagnostic and then operative hysteroscopy in the outpatient setting. Hysteroscopic sterilization using Essure is an effective method applicable to the outpatient setting, but its cost is inhibiting its widespread use.

Advances in the technique over the past two decades have revolutionized gynaecological surgery and provided a vastly improved service for patients. At the same time, some of these advances have been associated with considerable controversy, and many opinions are forcefully expressed without much factual basis. This chapter aims to discuss the basics of laparoscopy and its application, providing some of the evidence from the literature where possible. The revolution in therapeutic techniques probably started with the report of the first laparoscopic hysterectomy (Reich et al 1989) and, with advances in instrumentation, light sources and camera systems, continued apace throughout the 1990s. However, a few practitioners attempted procedures that were beyond either their surgical training or ability, and responsible bodies rapidly concluded that regulation was required. History Examination of the body cavities using instrumentation has been practised by clinicians over many centuries. Most of the early techniques involved inspection of the bladder and urethra (Bozzini 1805). Light sources were introduced initially with alcohol flames (Desmoreaux 1865), and subsequently the incandescent light bulb. The first inspection of the peritoneal cavity was through the posterior fornix in the early 20th Century (von Ott 1901). Examination of other cavities was described soon afterwards (Jacobaeus 1910), with carbon dioxide used for insufflation more than a decade later (Zollikoffer 1924). The first diagnosis of an ectopic pregnancy followed (Hope 1937), as did female sterilizations. Veress first reported the spring-loaded insufflation needle as a technique for introducing a pneumothorax in patients with tuberculosis (Veress 1938). Further advances were relatively slow with few clinicians inspired by the new techniques. The first description of sterilization in English was not until 25 years later (Steptoe 1967). Few therapeutic procedures were performed laparoscopically, although the technique gained widespread support for diagnosis. First, both the surgeon and the assistant need to have an excellent view of the operating area. Second, the surgeon needs to be in a comfortable position, and third, the instrumentation needs to be arranged systematically and consistently. Many experienced surgeons place the television screen directly in front of themselves and behind the assistant. Any laparoscopic procedure can only be performed safely if clear images are presented to the surgeon.

However fungus link to diabetes buy 200 mg ketoconazole with amex, the drawback of using less contrast material is the shortened duration of the contrast bolus, which increases the challenge for proper coordination of imaging with opacification of the arteries. That is to say, if scanning is too fast, imaging may occur prior to complete opacification of the target vasculature, resulting in suboptimal arterial contrast enhancement and poor arterial visualization. Alternatively, if scanning is slow or performed too late, images would illustrate the venous phase of the bolus with suboptimal arterial enhancement, Consequently, it is important to accurately determine circulation time to achieve an optimal scan. In this technique, a small test dose of contrast material, 10 to 15 mL, is infused at a rate of 3 to 4 mL/sec followed by repetitive scans obtained at the level of the upper abdominal aorta at 2-second intervals. The main drawbacks with this technique include the higher volume of contrast administered and the additional ionizing radiation dose associated with the timing bolus. In this technique, a region of interest is selected in the upper abdominal aorta at approximately the level of the celiac artery. Although this technique results in a lesser amount of contrast administered than the timing bolus technique, the additional nondiagnostic ionizing radiation dose is comparable to that required for a timing test bolus scan. The drawback with this technique is the time lag between contrast opacification exceeding the threshold and actual initiation of the scan. For instance, selecting too low a threshold may initiate the scan before peak opacification is achieved. Alternatively, selecting too high a threshold may miss the peak enhancement phase or not trigger the scan at all. The patient is placed in the supine position and intravenous access is obtained in the upper extremity. The phased-array coil permits implementation of parallel imaging techniques, which can shorten acquisition times and increase image resolution. The arms are propped up anterior to the level of the coil to avoid wrap-around artifact. For instance, this techniques enables the detection of microscopic or intravoxel fat within adrenal adenomas. The acquisition times are generally less than 1 second permitting essentially motion-free T2-weighted images. This technique is useful in uncooperative patients or patients who cannot adequately breath-hold. The complete volume of the adrenal glands and kidneys may be imaged within a single breath-hold to minimize respiratory and other motion artifacts and allow advanced 3D image postprocessing. Contrast infusion time is the duration of the contrast infusion (10 sec for 20 mL of contrast infused at 2 mL/sec). If a centric phase ordering is used, the central lines of k-space are acquired at the beginning of data acquisition and scan delay is typically timed by simply adding 2 seconds to the circulatory time. The addition of 2 seconds minimizes the risk for ringing artifacts that can occur if central k-space views are sampled during the rapid rise in gadolinium concentration. With alternate acquisition of the tagged and nontagged images and subtracting these two data sets, a bright blood image, without background signal, can be obtained. It is less effective in regions of slow flow, such as within the peripheral arteries, where blood in the imaging volume is not being adequately replaced by tagged blood. Third, extensive computational time is required to integrate the independent data from multiple channels. Finally, the signal-to-noise ratio will be decreased inversely with the acceleration factor because of the under-sampling of k-space. In any case, the source data should be routinely evaluated to corroborate specific findings. This technique uses the difference in signal detected by receiver coils positioned over different parts of the body. By incorporating the differences in sensitivity of multiple coils to detect signal from the same source, information regarding spatial localization may be obtained and may reduce the number of phase-encoding steps required to produce an image. First, special coils must be designed with independent coil elements having their own receiver channels. Because the renal artery may be tortuous in course, segments of the artery may course in and out of the visualization plane resulting in the appearance of pseudostenoses. This modified technique allows complete visualization of the renal artery in one plane of section. The major limitation of this technique is dependence on accurate designation of the course of the renal artery. In addition, because the images are only a single voxel in thickness, small or thin structures may not be included in the tomogram image. Then, the value of each voxel is determined by the maximum value along an array directed perpendicular to the imaging plane and through the volumetric data set. By subtracting the precontrast data set from the postcontrast data set, the resulting postprocessed data set will contain only information regarding the distribution of contrast material. Various filters may be applied to the source data to create different colors or degrees of opacity corresponding to each voxel value. In this manner, certain voxel values may be emphasized or minimized to evaluate specific structures. Accessory renal arteries and unexpected anatomic variants may be easier to appreciate with these images. The limitation of this technique is the potential to create or overlook pathology because many of the attributes of the image are arbitrarily determined. For instance, the colors and degrees of transparency are user-defined variables and may be vulnerable to error. For renal artery stenosis, the segment of vessel involved, length of stenosis, and grading of degree of stenosis should be reported. Finally, other nonvascular findings such as renal size, renal parenchymal assessment, and other incidental findings should be included. The aorta should be described in regard to its course, caliber, and presence of pathology (atherosclerotic disease, aortic aneurysm, aortic dissection, etc.

The differentials will therefore include adnexal torsion anti fungal oil for scalp ketoconazole 200 mg purchase without a prescription, acute fibroid degeneration, urinary tract infection and appendicitis. However, a chronic hydrosalpinx will have the appearance of a thin-walled structure, not obviously tender on probing and often detected coincidentally (Timor-Tritsch et al 1998). Uterine leiomyomas these may undergo torsion if pedunculated in nature, may prolapse through the cervix or may undergo degeneration, especially during pregnancy. In fibroid degeneration, the patient is often systemically unwell, with pyrexia, leucocytosis and generalized abdominal tenderness. The ultrasound characteristics of leiomyomas are well documented and cystic areas can be visualized within the fibroid if it is degenerating. Advances in the management of uterine myomas have resulted in a need to provide accurate pretreatment information concerning their size, quantity and location. This is especially true with the increasing use of minimally invasive techniques of fibroid resection. The 88 Acute urinary retention A full bladder may sometimes be confused with an ovarian cyst. If there is any doubt and the patient is unable to void urine, a catheter should be passed to ensure the bladder is empty. Pelvic pain with no mass on scan In the absence of pathology on scan, blood should be taken for leucocytosis and culture. A transvaginal scan may reveal evidence of adhesions and loculated fluid, which may be indicative of previous pelvic or abdominal pathology. Medical, surgical and urological opinions should be sought where indicated, with early recourse to laparoscopy in those patients who have persistent or worsening symptoms. Numerous studies have shown that simple, unilocular cysts measuring <5 cm in diameter are associated with a very low risk of malignancy (Kroon and Andolf 1995). Blood should be taken for tumour markers and emergency laparotomy should be avoided if at all possible, to allow for adequate oncological work-up of the patient if indicated. Other chronic surgical and medical conditions are more predominant in the older age group, such as diverticulitis, constipation and urinary tract infections. Early recourse to advice from other specialties should be considered in women with pelvic or abdominal pain. A full history and clinical examination is essential, along with resuscitation of the patient. Undirected endometrial sampling alone has no role in the evalu- ation of abnormal uterine bleeding. The addition of a negative contrast medium, such as saline, into the uterine cavity addresses this problem. When all these have been excluded, a diagnosis of dysfunctional uterine bleeding can be made. History, clinical examination and pelvic ultrasound will help to elucidate the cause. Disease of the genital tract in this age group will focus on benign rather than malignant conditions. Benign pelvic conditions will include fibroids, endometrial and cervical polyps, cervicitis, adenomyosis and endometriosis, along with pelvic infection and foreign bodies. Systemic problems contributing to abnormal uterine bleeding will include coagulation disorders, chronic liver and renal disease, and thyroid dysfunction. Iatrogenic causes will include anticoagulant therapy, intrauterine contraceptive devices and hormonal preparations. There needs to be heightened suspicion of an underlying systemic disease in younger patients presenting with heavy vaginal bleeding, as up to 20% (Kadir et al 1998) may have a coagulopathy. Screening for a coagulopathy is also advised in women with abnormal vaginal bleeding who fail medical or surgical therapy. The primary goal with acute uterine bleeding will be to ensure cessation of bleeding, usually with a combination of therapies, such as antifibrinolytics, high-dose progestogens, gonadotrophin-releasing hormone analogues or the Mirena intrauterine system, until definitive management can be effected. Occasionally, urgent examination under anaesthesia with the introduction of a uterine cavity balloon is indicated to stop the bleeding. Interventional radiology with uterine artery embolization may have a role in acute management. The postmenopausal patient Abnormal vaginal bleeding in this age group should be attributed to malignancy until proven otherwise. Malignant tumours of the endometrium, cervix, vagina and vulva may all present with vaginal bleeding, as can ovarian tumours, such as granulosa cell tumours. It is wise to confirm that the bleeding is genital tract in origin, as occasionally haematuria and rectal bleeding may present as suspected postmenopausal vaginal bleeding. Its integration into the gynaecology emergency service facilitates more rapid diagnosis in a number of gynaecological conditions. It also helps to exclude gynaecological pathology, ensuring prompt referral to other specialties and multidisciplinary teams. Central to its appropriate use will be training and supervision, with up-to-date protocols and regular audit, and awareness of the limitations of personnel and the equipment. Visualization of an intrauterine gestation will generally exclude an ectopic pregnancy. Once an ectopic pregnancy has been excluded, early pregnancies should be given the benefit of the doubt. The sonographic appearances of retained products of conception in the immediate postnatal period are variable; management should be based primarily on clinical findings. There are no pathognomonic features specific to adnexal torsion; a high degree of clinical suspicion is paramount. Undirected endometrial sampling alone has no role in the evaluation of abnormal uterine bleeding. Transvaginal saline sonohysterography is as predictive as hysteroscopy in the detection of endometrial pathology.

These changes have been driven by the demands of the patient and clinician to provide a rapid, accurate diagnosis, with the minimum of investigations and invasive procedures. They are underpinned by national standards and guidelines (Department of Health 2003, Royal College of Obstetricians and Gynaecologists 2006). Furthermore, changing from traditional care pathways to more costeffective, patient-centred approaches to medical practice lies at the heart of modern health service management (Department of Health 2000, Jones 2008). Therefore, in order to deliver modern acute gynaecological services, gynaecologists will have to learn these new skills (Jones 2005). They have superiority over transabdominal probes because of the higher resolution of pelvic anatomy. This is a more comprehensive term which would include the assessment of patients with non-acute gynaecological symptoms such as menstrual disorders, postmenopausal bleeding and chronic pelvic pain. The ultrasound diagnosis may determine if the patient is suitable for minimal access surgery or they may need a laparotomy and a multidisciplinary oncology team. In this way, preoperative ultrasound assessment of the patient will improve patient counselling and satisfaction with treatment. This chapter deals with assessment of the patient presenting with acute symptoms, in whom gynaecological pathology is suspected. By adopting a problem-orientated approach, the aim is to provide a series of reproducible pathways allowing effective investigation of these patients. The second part of the chapter will give an overview of the role of pelvic ultrasound in the evaluation of acute pelvic pain and vaginal bleeding in women with a negative pregnancy test. A portable machine can be a wise investment if it is to be shared, for example, with the delivery suite, or to allow for ultrasound-guided procedures in the operating theatre. The ultrasound machine should not be more than 5 years old (Royal College of Radiologists/Royal College of Obstetricians and Gynaecologists 1995). However, angiographic embolization has now become accepted as the treatment of choice for potentially life-threatening obstetric and gynaecological haemorrhage, and selected interventional radiological techniques can be carried out in the outpatient setting with minimal morbidity and complication rates. It is particularly useful in patients in whom surgery is relatively contraindicated; for example, extensive previous abdominal surgery or during pregnancy. Ultrasound-guidedovariancystaspiration It is now possible to aspirate ovarian cysts transvaginally. Under ultrasound control, a needle is then passed through the transvaginal probe and fluid is aspirated from the cyst or collection. The size of the needle is adjusted according to the predicted viscosity of the fluid. When serous-type fluid is being aspirated, an 18- or 20-gauge needle will suffice. If the ovarian cyst is easily accessible and thin walled, it may not be necessary to administer intravenous sedation to cover the procedure. It is important that the ovarian cysts are unilocular and thin walled if the technique is going to be successful and safe. Subtle, superficial, internal mural nodules or small papillary excrescences should be searched for meticulously because these features may indicate a malignant lesion, in particular a borderline tumour. With careful attention to ultrasound surveillance, cyst aspiration can be performed safely (Caspi et al 1996, Troiano and Taylor 1998). In other cases, cysts will recur and it is important to remember that cytology alone is not sufficiently accurate to exclude malignancy. Cyst recurrence after drainage is higher than if the capsule is removed (Balat et al 1996), but cyst fluid cytology is not always representative of the cyst wall pathology (Dietrich et al 1999). Haemorrhagic cysts that do not resolve spontaneously or those that are symptomatic may be aspirated, usually via an 18- or 20-gauge needle, resulting in complete relief of symptoms.

Endovascular repair may be a temporizing step in patients too ill for immediate surgery. Like thoracic dissection, isolated aortic dissection is associated with hypertension. Patients usually present with back pain, peripheral ischemia, and signs of distal embolization but may be asymptomatic. Because of its low incidence, the natural history is unknown, although rupture has been reported in up to 25% of patients in one study. Treatment may include open or endovascular repair in patients with major aortic branch occlusion, aortic expansion, extension of the dissection, and aortic rupture.

Spontaneous infrarenal abdominal aortic dissection presenting as claudication: case report and review of the literature. There is controversy regarding the exact size at which an aneurysm should be repaired. A certain length of nonaneurysmal infrarenal aortic length, depending on the device used, must be present for proper placement of the proximal attachment of the stent graft. Aortic neck angles more than 45 degrees may pose problems with implantation and may stress the device. Additionally, the iliofemoral vessels must have a certain (device-dependent) caliber and straightness. Patients are usually ambulatory within 24 hours after the procedure and are discharged on the third or fourth day after the procedure. Endograft placement is relatively new, and studies regarding its long term efficacy are still being performed to define its clinical role better. However, a higher percentage of patients (20%) who underwent endovascular repair required reinterventions (compared with 6% in the open-repair group). Therefore, although perioperative mortality was higher in patients who underwent open repair, a higher percentage of patients in the endovascular repair group required reinterventions, and there was no significant difference in 4-year mortality rates between the two groups. However, the overall survival rate was not significantly different between the two groups at 2 years. Although aneurysm-related death was more frequent in patients who had undergone open repair, reinterventions were required more often in patients who had undergone endovascular repair.

B, After successful placement of coils, there is stagnant flow within the aneurysmal lumen of the right internal iliac artery. C, Subsequent placement of a stent graft across the right internal iliac artery origin excludes inflow to the aneurysm. The combination of proximal sealing of the aneurysm with the stent graft and distal occlusion of the artery, thus preventing retrograde flow from the contralateral iliac artery, results in total exclusion of the aneurysm from the circulation.

Women who conceive should then be offered early pregnancy clinic follow-up with ultrasonography and supportive care fungus gnats larvae purchase cheap ketoconazole on-line. Counselling Counselling should be offered to all patients attending a recurrent miscarriage clinic. This chance decreases with each subsequent miscarriage, although even after six miscarriages, the chance of a successful pregnancy is still over 45%. Treatmentofunexplained recurrentmiscarriage Treatment of recurrent miscarriage where a potential cause has been identified has been discussed above. The value of continued reassurance and psychological support has been demonstrated (Stray-Pedersen and Stray-Pedersen 1984), with a 75% chance of a live birth in unexplained recurrent miscarriage. This support should include care in a specialist clinic, psychological support, easy access to a named contact, close monitoring including ultrasonography, appropriate reassurance, and helpful and caring staff. Any empirical treatment or treatment in clinical trials needs to have a sound scientific and statistical basis, and should Conclusion Recurrent miscarriage needs to be differentiated from sporadic miscarriage, and investigated thoroughly. Careful evaluation and treatment of this aetiologically diverse condition are necessary. Continued research into the causes and effective treatments is appropriate and best managed through a dedicated recurrent miscarriage clinic. Sporadic miscarriage is common and increasing in incidence because of increasing maternal age. Management may involve expectant and medical treatment as well as surgical evacuation. Miscarriage is the most common complication of pregnancy and accounts for the majority of emergency gynaecology consultations and admissions. Miscarriage is defined as the loss of an intrauterine pregnancy before 24 completed weeks of gestation. Sporadic miscarriage occurs in approximately 15% of all clinically recognized pregnancies, and this rises with maternal age. Treatment of miscarriage is usually with surgical uterine evacuation, although medical and expectant management should be discussed. There is a small mortality rate with miscarriage, usually due to haemorrhage or sepsis. All treatments for recurrent miscarriage need to be evaluated in controlled randomized prospective trials because of the high likelihood of live birth in any placebo group.
