Cerebrospinal fluid drainage is recommended as a spinal cord protective strategy in open and endovas- cular thoracic aortic repair for patients at high risk of spinal cord ischemic injury gastritis natural cures nexium 40mg amex. Spinal cord perfusion pressure optimization using techniques gastritis symptoms weight loss best nexium 40mg, such as proximal aortic pressure main- tenance and distal aortic perfusion gastritis diet guidelines order 40mg nexium free shipping, is reasonable as an integral part of the surgical diet for hemorrhagic gastritis nexium 40 mg cheap, anesthetic, and per- fusion strategy in open and endovascular thoracic aortic repair patients at high risk of spinal cord isch- emic injury. Moderate systemic hypothermia is reasonable for protection of the spinal cord during open repairs of the descending thoracic aorta. Adjunctive techniques to increase the tolerance of the spinal cord to impaired perfusion may be consid- ered during open and endovascular thoracic aortic repair for patients at high risk of spinal cord injury. These include distal perfusion, epidural irrigation with hypothermic solutions, high-dose systemic glu- cocorticoids, osmotic diuresis with mannitol, intra- thecal papaverine, and cellular metabolic suppres- sion with anesthetic agents. Neurophysiological monitoring of the spinal cord (somatosensory evoked potentials or motor evoked potentials) may be considered as a strategy to detect spinal cord ischemia and to guide reimplantation of intercostal arteries and/or hemodynamic optimization to prevent or treat spinal cord ischemia. Computed tomographic imaging or magnetic reso- nance imaging of the thoracic aorta is reasonable after a Type A or B aortic dissection or after prophy- lactic repair of the aortic root/ascending aorta. Computed tomographic imaging or magnetic resonance imaging of the aorta is reasonable at 1, 3, 6, and 12 months postdissection and, if stable, annually thereafter so that any threatening enlargement can be detected in a timely fashion. When following patients with imaging, utilization of the same modality at the same institution is reasonable, so that similar images of matching anatomic segments can be compared side by side. If a thoracic aortic aneurysm is only moderate in size and remains relatively stable over time, magnetic resonance imaging instead of computed tomographic imaging is reasonable to minimize the patient’s radiation exposure. Surveillance imaging similar to classic aortic dissection is reasonable in patients with intramural hematoma. If there is concern about a leak, a predischarge study is recommended; however, the risk of renal injury should be borne in mind. All patients should be receiving beta blockers after surgery or medically managed aortic dissection, if tolerated. For patients with a current thoracic aortic aneu- rysm or dissection, or previously repaired aortic dis- section, employment and lifestyle restrictions are reasonable, including the avoidance of strenuous lifting, pushing or straining that would require a Valsalva maneuver. Thoracic aortic aneurysms without dissection comprise a smaller subset of patients with aortic emergencies. Because there are varying presenting complaints, these diagnoses can be challenging to make, and a missed diagnosis often leads to significant morbidity and mortality. The initial tear may propagate proximally and/or distally and affect any arteries branching from the aorta, resulting in varied clinical presentations. Because of this, as well as the relative infrequency of the diagnosis, aortic dissection is a diagnosis that can be challenging for the emergency physician. Clinical Presentation the most common presenting symptoms of an aortic dissection are chest pain and/or back pain. Although a pulse discrepancy between extremities is classically associated with aortic dissection, this sign has been found to have a sensitivity of only 31%. Focal neurologic complaints also suggest dissection when present, but the lack of neurologic deficits does not help to exclude the diagnosis. Aortic dissections of the ascending aorta are twice as common as those involving the descending aorta. The Stanford system divides aortic dissections into 2 groups based on involvement of the ascending aorta, correlating with the likely treatment course: Type A (proximal): involves the ascending aorta with or without involvement of the descending aorta (usually surgical management) Type B (distal): involves only the descending aorta (usually medical management). Diagnostic Modalities Chest radiography Chest radiography is easily obtained in the emergency department and is often one of the first tests available in the evaluation of a patient with aortic dissection. The pres- ence of a widened mediastinum (>8 cm) is concerning for dissection. Other findings include an abnormal aortic contour, the calcium sign (separation of calcific intima from outer aortic soft tissue), left pleural effusion, and depression of the left mainstem bronchus. Abnormalities on chest radiography are present in greater than 80% of patients with aortic dissection. Classification of aortic dissection by the Stanford system (labels at top) and Debakey system (labels at bottom). In addition, unstable patients may not be able to leave the emergency department bay for the study and other modalities must be considered. Laboratory studies There is no universally accepted biomarker or assay to diagnose or rule out aortic dissection. The D dimer assay has been suggested as an option to rule out low-risk patients for aortic dissection, much as it is used to rule out low-risk patients for pulmo- nary embolism. Multiple studies have shown increased D dimer levels in patients with aortic dissection. Decision rules One of the challenges in evaluating patients for aortic dissection is that there have been no well-established decision rules to help categorize patients as low risk for aortic the way the Wells criteria do for the evaluation of patients with suspected pulmonary embolism. In 2010, a guideline was published for the evaluation and treat- ment of patients with thoracic aortic disease. Within the pathway, patients classified as moderate or high risk have aortic imaging. Recently, this risk-assessment tool was applied to the International Registry of Acute Aortic Dissection and was found to have a sensitivity greater than 95%. It is also unclear how the tool will perform in an undifferentiated patient population with suspected aortic dissection. Prospective investigation may shed further light on the general appli- cability of this tool. Treatment Medical All patients with aortic dissections require aggressive blood pressure and heart rate control to limit shear force on the aorta, which can lead to propagation of the dissec- tion. The target systolic blood pressure is 100 to 120 mm Hg and goal heart rate is 60 beats per minute. Esmolol is a good choice given that it is a short-acting agent and can be titrated to effect (starting dose 500 mg/kg bolus, followed by infusion at 50 mg/kg/min; rebolus and increase drip rate by 50 mg/kg/min every 4 minutes until target vital signs have been reached). It is important that nitroprusside is only added after b-blockers because it can cause reflex tachycardia when used indepen- dently, thereby increasing aortic stress and potentially resulting in a worsening dissec- tion. Calcium channel blockers Although calcium channel blockers such as verapamil or dil- tiazem are not commonly used in the medical management of aortic dissection, they can be substituted if the patient has a contraindication to b-blocker administration. Surgical Most patients with an aortic dissection involving the ascending aorta require surgical intervention. If cardiac surgery is not available at the diagnostic center, patients require emergent transfer to a tertiary care hospital. While awaiting surgical interven- tion or transfer, it is crucial to continue aggressive medical management. Some patients with a descending aortic dissection are also considered for surgical interven- tion, including those with aortic rupture or evidence of visceral or limb ischemia. Older patients (>70 years) and those with preoperative shock have been shown to have higher surgical mortality. With this procedure, commu- nication is established between the true and false lumens of the aorta to allow blood flow to arteries originating from the false lumen. Surgical aortic fenestration has been suggested as an alternative option to aortic replacement as well as in the case of con- traindicated or failed endovascular stenting. Aortic Emergencies 795 Clinical Presentation Unruptured aneurysms are often asymptomatic, resulting in a diagnosis that is chal- lenging to make. Other symptoms that may also be present include back or flank pain, hypotension, and syncope. The triad of syncope, abdominal pain, and hypotension is highly suggestive of a vascular catastrophe. This finding increases in sensitivity with enlarging aneurysm size as well as with smaller abdominal girth. In 61% of cases, the diagnosis was initially missed and only identified once there was hemodynamic compromise. When evaluating the aorta with ultrasound, it is important to obtain measurements at multiple levels and to include both axial and longitudinal views. Although traditionally performed by ultrasound technicians and interpreted by radi- ologists, there have been multiple studies evaluating the use of bedside ultrasound by the emergency physician. Both the intramural thrombus (solid arrow) and the aorta lumen (dashed arrow) are depicted. Once an asymptomatic aneurysm is greater than 5 cm, operative repair is generally recommended. Multiple large-bore intravenous lines should be placed, and infusion of crystalloid should begin immediately in hypotensive patients. Uncrossmatched packed red blood cells can be initiated and then switched to crossmatched packed red blood cells when available.

Introduction At admission to a hospital, a patient usually knows less about his or her illness than the department nurse. First, these syndromes are so uncommon that a nurse will probably never have had to deal with it before and will therefore neither recognize the syndrome nor the symptoms. The specific nature of these disorders requires great dedication of both the nurse or nursing staff and the patient. The nurse must listen professionally and critically to the patient if they are to work together well. However, to a greater or lesser degree hypermobile joints, highly elastic skin and bruising are common to all types. These play a role in addition to the indication for admission and should be included in the history taking of the nurse. Values – belief pattern When designing a specific nursing plan, basic assumptions are the following. Each patient experiences medical problems differently and each one tries to maintain mental 3 and physical health in his or her own way. Activity patterns are partially determined by the degree of pain and fatigue experienced. The patients themselves generally know their 2 individual ‘instructions for use’ well. Regarding dietary and metabolic patterns, factors such as diet, stomach and intestinal pain, constipation or complications such as a rectum prolapse will influence how a patient deals with the problems. Each patient experiences, accepts and deals with the burden of a chronic disorder differently. This applies both to the symptom-related problems as well as to the problems leading to hospitalization. It is also important to bear in mind that the patient’s condition may vary greatly each day or even throughout the day. It is not unusual for a patient to be able to perform all the normal daily activities independently in the morning and to need help and assistance to change clothing in the evening. Case study A 45-year-old woman checks in at the gynaecology department in order to be admitted for removal of the uterus via the abdominal wall (abdominal uterus extirpation). When the patient is greeted upon arrival, the nurse shaking the patient’s hand notices that it feels ‘strange’, like a velvet flannel with bones. Notably, the patient has taken along her own mattress and pillow since she is unable to lie on hard hospital beds because of neck and back pain resulting from hypermobile joints. Below is described how the process of admission, pre-operative screening, pre-, per- and post- operative support, convalescence and discharge can optimally be controlled. Make sure there are clear arrangements about this particularly in relation to the department’s prevailing policy on pain control. If a patient is already using pain killers, the department’s policy may need to be adapted to this to prevent the patient either from becoming overdosed or from having to change to a medication cited in the formulary. In addition, sometimes when sticky plaster is removed, part or all of the epidermis is torn. In such cases, other solutions for affixing bandages must be sought, such as elastic bandages or compresses. You and the patient should keep an eye on this; if necessary, ask a dietician to set up a diet enriched with fibre and with plenty of liquids. You and the patient should keep an eye on this and take timely action, for instance by taking measures such as the use of lactulose and a micro enema and avoidance of medication known to aggravate these 3 problems. When anaesthetizing such patients, a number of precautions should be kept in mind. The anaesthesiologist should also carefully monitor the patient’s maxillary joints while inserting a tube into his or her throat. The risk of a headache after the operation is reduced by 4 repositioning of the jaws and removing the tube as quickly as possible if this occurs. The vessels do not contract well either or the collagen around the vessels is less tight, increasing the chances of serious haematomas. Huge bruises can result from a misplaced injection or needle insertion because the tissue around the vessels is less firm. It is advisable to ask someone with a great deal of experience with injections or needle insertion to perform this task, to prevent extra pain and injury. This is the result of hypermobile and sometimes damaged joints, joint capsules and muscles. It is advisable to discuss the possibilities of pharmacological pain management before surgery and to call a physiotherapist early on after surgery for support during the often slow 5 convalescence. The patient may require more exercise that the standard operation protocol dictates. However, if the patient suffers from complaints of the back and pelvis resulting from lying on a hard operation table, it may not be possible to follow the mobilization protocol because a few days of bed rest 6 are needed before mobilization can be initiated. In the case above, the patient took her own pillow along (remember the risk of sub-luxation of the maxillary joints) to enhance her comfort when lying down and sleeping. Bedsores can be prevented by changing positions, through massage and by mobilizing the patient as early and much as is possible. Due to poor quality of vessel walls, poor vessel contraction and possibly bleeding disorders (see chapter 11), the risk of continued bleeding after the operation is higher. In cases of an abdominal injury, a spica elastic bandage can be applied to prevent further bleeding. Because of the close contact between the nurse and patient at the ward, the nurse will be the first to notice the symptoms of these complications; she or he should take action immediately. The individual need for further care will have to do with factors such as the number of days which have elapsed since the surgery took place, the patient’s condition and ability to manage independently prior to the operation and the extent of pain and disability. A slow recovery and extended convalescence period often have consequences for the duration of the hospitalization. In order not to extend this time longer than needed , it is important to 336 Chapter 23 give timely attention to the issue of whether homecare and possible other resources have to be provided or not. Although there are differences in symptoms and degrees of seriousness, three problems occur among patients to a greater or lesser degree: 1) hypermobile joints, 2) highly elastic, fragile skin and 3) easy bruising. By doing so, he or she can prevent a number of complications and also reduce their seriousness. Pain in ehlers-danlos syndrome is common, severe, and associated with functional impairment. Introduction Occupational therapy does not focus on a particular disease, disorder, or the treatment of symptoms, but rather on performing daily activities. Together with the patient, occupational therapists try to ensure that, as far as possible, patients are able to do what they want to do despite their limitations.

The initial paper presentedten probands with a novel aortic aneurysm syndrome characterized by the clinical triad of hypertelorism, bi d uvula/ cleft palate and aortic/arterial aneurysms and tortuosity (1). Although these presented the most typical characteristics, a widespread involvement of different organ systems was also recognized. These included craniofacial (eg craniosynostosis), skeletal (joint laxity and contractures), integumental (skin hyperextensibility, dural ectasia) and ocular ndings (eg strabismus). Shared features include aortic root aneurysm, pectus deformities, scoliosis and arachnodactyly. Distinguishing ndings are craniosynostosis, hypertelorism, cleft palate or bi d uvula, cervical spine instability, club feet, and most importantly widespread arterial aneurysms with tortuosity and early aortic rupture. Interestingly, in some patients the bi d uvula is the only visible marker to identify people at risk for aortic aneurysms. Cardiovascular Manifestations In the vascular system, the most common and prominent nding is the dilatation of the aortic root at the sinuses of Valsalva, which if undetected, leads to aortic dissection and rupture. In addition to the aortic root aneurysms, aneurysms throughout the arterial tree have been described, most prominently in the side branches of the aorta and the cerebral circulation. Finally, another striking nding is the presence of arterial tortuosity, which is usually most prominent in the head and neck vessels. Vertebral and carotid artery dissection and cerebral bleeding have been described; however, isolated carotid artery dissection in the absence of aortic root involvement has not been observed (1, 4, 12). Joint hypermobility is very common and does include congenital hip dislocation and recurrent joint subluxations. Paradoxically, some individuals can show reduced joint mobility, especially of the hands (camptodactyly) and feet (club feet). Other recurrent skeletal ndings include spondylolisthesis, acetabular protrusion and pes planus (1, 4). Sometimes the uvula is not bi d but has an unusual broad appearance with or without a midline raphe. Another common presenting feature in the more severely affected patients is craniosynostosis. In the latter all sutures can be involved: most commonly the sagittal suture (resulting in dolichocephaly), but also the coronal suture (resulting in brachycephaly) and metopic suture (resulting in trigonocephaly). In our experience, ectopia lentis is not observed, although in the literature minimal lens(sub)luxation has been reported (14). Less common associated ndings requiring further exploration include submandibular branchial cysts and defective tooth enamel (4). Cutaneous manifestations In persons without craniofacial features, important cutaneous ndings can provide the clue towards diagnosis. The common neuroradiological ndings are dural ectasia and Arnold-Chiari type I malformation (16). Other recurrent ndings that need further documentation include muscle hypoplasia, dental problems with enamel dysplasia, allergic disease with seasonal allergies, asthma/ sinusitis, eczema and important gastro-intestinal problems: food allergy, eosinophilic esophagitis, in ammatory bowel disease. A distinguishing feature, however, might be the presence of early- onset osteoarthritis. Cardiovascular anomalies with mitral valve prolapse, mitral regurgitation, and aortic regurgitation may occur, but aortic root dilatation is usually mild. Minimal subcutaneous fat, abdominal wall defects, cryptorchidism in males, and myopia are also characteristic ndings. About two third of cases are the consequence of de novo mutations, whereas the other one third are familial. In general, the more severe cases with marked craniofacial and skeletal ndings are the consequence of a de novo mutation, whereas the milder cases tend to be familial. Although it should be stressed that the clinical overlap is so large, that it is impossible to predict the correct causal gene based on the clinical signs. Treatment and managment Natural history Comparison of the natural history of Marfan syndrome and Loeys-Dietz syndrome has lead to two important lessons. Preventive treatment with beta-blockers is believed to slow down the aortic root growth but in general this does not prevent aortic surgery at later age. In a placebo-controlled trial on Marfan mice, losartan resulted in signi cantly reduced aortic growth compared to atenolol, despite the similar hemodynamic effect. In addition, a dozen other trials with different designs and inclusion criteria have been initiated in Belgium, France, Italy, the Netherlands, Taiwan and the United Kingdom (43-46).

The exam- iner must try to define the complaint as completely and accurately as pos- sible gastritis symptoms burning buy discount nexium online. Identify the onset of the symptoms gastritis diet 600 buy nexium with mastercard, including the time frame before the examination and whether it was acute or insidious gastritis pdf nexium 20mg without a prescription. Try to pinpoint the exact location of the symptoms and any zone to which it radiates gastritis diet effective 40mg nexium. Charac- terize the nature of the pain: is it burning or radiating (nerve), or is it an aching related only to activity (tendonitis)? Is it associated with any other symptoms, such as neck pain (referred pathology from the cervical spine) or wrist pain (distal radioulnar joint problem)? For example, in a throwing athlete, when during the pitch or throw does the pain occur? Medial elbow pain when the arm is in the “cocking position” suggests medial collateral ligament pathology, whereas medial pain during follow-through suggests involvement of the flexor pronator group. The elbow is commonly involved (and sometimes one of the first joints affected) in inflammatory arthritides, so it is important to elicit a history of other joint complaints, known arthritis, and family history. Is there a history of skin problems (lupus, dermatitis, psoriasis) or gastrointestinal 370 M. Numbness, tingling, and weakness may be obvious clues to neurologic involvement, but sometimes nerve entrapment syndromes present with pain only. In addition to inquiring about tingling or numbness, ask about weakness or loss of dexterity. Perhaps the most important part of the history is determining how the symptoms interfere with function, as this directs the treatment more than any other factor. For example, inability to flex the elbow completely is well tolerated by most patients, because we generally rely on an arc of 30 to 130 degrees for most activities of daily living. But in the patient with rheumatoid arthritis, for example, in whom shoulder motion is also com- promised, elbow restriction may interfere with their ability to feed or clean themselves. Physical Examination the examination of the elbow begins with inspection, palpation, range-of- motion assessment, and evaluation for strength and neurovascular integ- rity. These features are then followed by special tests designed to evaluate specific conditions, based on a differential diagnosis from the history and initial tests. A thorough physical examination must also include a directed evaluation of the shoulder, wrist, and hand, and, when relevant, the cervical spine. Inspection begins with careful observation of elbow use as soon as one begins interaction with the patient. Are there obvious adaptive maneuvers that the patient uses to avoid pain or compensate for functional loss? A more formal visual exam is then performed to look for presence of swelling, ecchymosis, atrophy, asymmetry, or masses. One should evaluate the “car- rying angle” formed between the longitudinal axis of the humerus and the forearm, normally 10 to 15 degrees. With the elbow flexed 90 degrees, note that the normal bony prominences (medial and lateral epicondyles and the olecranon) form an equilateral triangle. Look for evidence of joint swelling laterally by inspection of the soft tissue triangle bordered by the radial head, olecranon tip, and lateral epicondyle. Include the anterior, medial, lateral, and posterior structures in an organized, systematic fashion. For example, lateral epicondylitis (lateral tennis elbow) causes focal tenderness over the lateral epicondyle. Tenderness more distally in the proximal forearm may instead suggest posterior interosseous nerve entrapment. Notice the presence of any bursae over the olecranon tip, occasionally containing fluid, palpable fibrous fragments, or both (olecranon bursitis). Palpate over the antecubi- tal fossa for any defect in the biceps tendon attachment (distal biceps tendon rupture). If passive motion is greater than active motion, consider pain, muscle, or nerve injury as possible causes. Patients tend to splint their elbow at 80 to 90 degrees following trauma because the capsule accommodates the maximum amount of fluid in this position. Crepitus over the radiocapitellar joint during pronation/supination may indicate synovial or chondral pathology, degenerative changes, or radial neck fracture. The extent of neurologic evaluation depends on the patient’s symptoms, but be familiar with sensory, motor, and reflex exam. Check for sensation to light touch in the distribution of the specific peripheral nerves. The specific nerve roots have overlapping innervation, but in general, the lateral aspect of the deltoid is the C5 der- matome, the dorsal first web space is C6, the middle finger tip is C7, and the ulnar aspect of the forearm and arm is T1. Strength testing depends on familiarity with the innervation of the various muscle groups. Elbow extension is from C7, which also provides finger exten- sion and wrist flexion. Reflex testing is performed for the biceps (C5), brachioradialis (C6), and triceps (C7). Vascular assessment includes palpation of the radial and ulnar arteries at the wrist and the brachial artery in the antecubital fossa. Additional specific physical examination tests may be useful depending on the condition suspected. When considering medial epicondylitis, check for pain on wrist flexion or forearm pronation against resistance. Medial collateral ligament sprain or attenuation is determined by applying a valgus stress to the 15 to 30 degree flexed elbow, looking to reproduce pain or joint opening. Lateral epicondylitis can be assessed by eliciting pain with wrist extension or grip, whereas radial tunnel syndrome is implied by pain with resisted middle finger extension or forearm supination. Gently tapping over a nerve in the vicinity of suspected entrapment or pathology repro- duces the symptoms, causing numbness, tingling, or pain in the nerve’s 372 M. During flexion and extension, the ulnar nerve may be “unsta- ble” and can be felt subluxating or completely dislocating out of its groove posterior to the medial epicondyle in the cubital tunnel. Following trauma, additional views are some- times helpful, including oblique and radial head views. Stress X-Rays Stress views may be helpful in evaluating the patient with a suspected tear of the medial collateral ligament. This view is achieved through manual stress, during which the clinician applies a valgus stress to the elbow in an effort to open up the medial side. A difference in medial gapping of more than 2mm between the affected and normal elbow is usually significant. Its current use about the elbow includes imaging occult fractures, tumors, infections, synovitis or other causes of joint effusion, and osteo- chondritis dissecans. It is occasionally useful in evaluating ligament dis- ruptions, but it is usually unnecessary in evaluating medial or lateral epicondylitis and rarely helpful in nerve entrapment syndromes. Technetium-99 Bone Scan Technetium-99 injected intravenously is taken up in areas of increased vascularity. Although it is very sensitive, this test is not very specific, because increased blood flow can occur as a result of fracture, infection, tumor, or arthritis. In patients with heterotopic ossification, serial bone scans may help determine when the process has become quiescent enough to permit safe bone mass excision. The Elbow 373 However, failure to demonstrate specific neurologic findings by electrodi- agnostic testing does not rule out their presence. This problem is common in the workup of the patient with early ulnar nerve symptoms, or the patient with suspected radial tunnel syndrome, in whom such tests are commonly negative. Arthroscopy the techniques and procedures for arthroscopy of the elbow have devel- oped more slowly than in other joints such as the knee, shoulder, or wrist. Because of the very tight concentration of nerves and blood vessels in the area, the depth of the joint capsule under the musculature, and the tight articular constraint, it can be difficult and involves more risk than arthros- copy at most other joints. Although it provides a minimally invasive means with which to visually inspect and, when necessary, to palpate the intraar- ticular structures, it is rarely used for diagnostic purposes alone.

The progestational challenge will occasionally trigger an ovulation in an anovulatory patient lymphocytic gastritis symptoms treatment buy nexium 40 mg visa. The tip-off will be a later withdrawal bleed gastritis weed purchase nexium discount, 14 days after the progestational challenge! In the absence of galactorrhea and if the serum prolactin level is normal (less than 20 ng/mL in most laboratories) gastritis xarelto discount 20 mg nexium overnight delivery, further evaluation for a pituitary tumor is unnecessary provided the patient has undergone a withdrawal bleed gastritis skin symptoms order generic nexium online. Random single samples for prolactin are sufficient, because variations in the amplitude of the spikes of secretion and the sleep-related and food-related increases appear to be attenuated in both functional and tumor hyperprolactinemic states. If the prolactin is elevated, imaging evaluation of the sella turcica is essential (as discussed below). At this point in the workup, the following statement is a useful clinical rule of thumb: A positive withdrawal bleeding response to progestational medication, the absence of galactorrhea, and a normal prolactin level together effectively rule out the presence of a significant pituitary tumor. However, to be complete, we should mention case reports with ectopic secretion associated with pituitary tissue in the pharynx, bronchogenic carcinoma, renal cell carcinoma, a gonadoblastoma, and 8, 9, 10, 11 and 12 women with amenorrhea and hyperprolactinemia due to a prolactinoma in the wall of an ovarian dermoid cyst or teratoma. Step 2 If the course of progestational medication does not produce withdrawal flow, either the target organ outflow tract is inoperative or preliminary estrogen proliferation of the endometrium has not occurred. Orally active estrogen is administered in quantity and duration certain to stimulate endometrial proliferation and withdrawal bleeding provided that a completely reactive uterus and patent outflow tract exist. The terminal addition of an orally active progestational agent (medroxyprogesterone acetate 10 mg daily for the last 5 days) is necessary to achieve withdrawal. In the absence of withdrawal flow, a validating second course of estrogen is a wise precaution. As a result of the pharmacologic test of Step 2, the patient with amenorrhea will either bleed or not bleed. If there is no withdrawal flow, the diagnosis of a defect in the Compartment I systems (endometrium, outflow tract) can be made with confidence. If withdrawal bleeding does occur, one can assume that Compartment I systems have normal functional abilities if properly stimulated by estrogen. From a practical point of view, in a patient with normal external and internal genitalia by pelvic examination, and in the absence of a history of infection or trauma (such as curettage), an abnormality of the outflow tract is unlikely. Outflow tract problems include either destruction of the endometrium, generally the result of an overzealous curettage or the result of an infection, or primary amenorrhea resulting from the discontinuity or disruption of the müllerian tube. Abnormalities in the systems of Compartment I are not commonly encountered, and in the absence of a reason to suspect a problem, Step 2 can be omitted. In order to produce estrogen, ovaries containing a normal follicular apparatus and sufficient pituitary gonadotropins to stimulate that apparatus are required. Step 3 is designed to determine which of these two crucial components (gonadotropins or follicular activity) is functioning improperly. Because Step 2 involved administration of exogenous estrogen, endogenous gonadotropin levels may be artificially and temporarily altered from their true baseline concentrations. Hence, a delay of 2 weeks following Step 2 must ensue before doing Step 3, the gonadotropin assay. Therefore, if the patient does not bleed 2 weeks after the blood sample was obtained, a high level can be safely interpreted as abnormal. The result of the gonadotropin assay in the amenorrheic woman who does not bleed following a progestational agent will be abnormally high, abnormally low, or in the normal range. The association between castrate or postmenopausal levels of gonadotropins and absent ovarian follicles due to accelerated atresia is very reliable, but not totally reliable. There are rare situations in which high gonadotropins can be accompanied by ovaries that contain follicles. This situation is usually associated with lung cancer and is so infrequent that, with a normal history and physical examination, routine chest x-ray is not warranted in amenorrheic patients. The rare cases of a true single gonadotropin deficiency are probably due to homozygous mutations in the gonadotropin genes. The mutated b-subunit genes produce alterations in the b-subunits that yield no immunoreactivity or bioactivity. Hence, hypogonadism will be associated with one high and one low gonadotropin level. Treatment with exogenous gonadotropins will achieve pregnancy in these rare patients. There is no specific symptom or symptom complex associated with hypersecretion of gonadotropins. Thus, these tumors are usually diagnosed because of tumor growth that results in headaches and visual disturbances. Previously it was believed that these tumors were very rare and more common in men. This belief was due to the difficulty in recognizing these adenomas, especially in women. Patients suspected of having a pituitary tumor, the nature of which is uncertain or puzzling, should have their gonadotropin and a-subunit levels measured. This is true whether the perimenopausal period is premature at age 25–35 or at the usual time. During the perimenopausal period, the remaining follicles may be viewed as the least sensitive of all follicles because they have remained in place and failed to respond to gonadotropins for many years. It is not unusual to encounter a pregnancy in a woman after a diagnosis of premature ovarian failure. In the resistant or insensitive ovary syndrome, the patient with amenorrhea and normal growth and development has elevated gonadotropins, despite the presence of ovarian follicles. In this condition, the ovarian follicles are unresponsive to stimulation compared with premature depletion of follicles in the most common type of premature ovarian failure. This syndrome may be due to absent or defective gonadotropin receptors on the follicles or a postreceptor-signaling 21 defect. Molecular biology studies of patients with premature ovarian failure are discovering rare cases of point mutations; e. In addition, translocations between regions 24 on X and Y chromosomes that share sequence homology have been reported in patients with secondary amenorrhea and ovarian failure. In these cases, laparotomy is the only definitive way to evaluate the ovaries, because follicles are 25 contained deep within the ovary, yielding only to a full thickness biopsy. Secondary amenorrhea caused by premature ovarian failure can be due to autoimmune disease. The ovaries contain normal-appearing primordial follicles, but developing follicles are surrounded by nests of lymphocytes and plasma cells with lymphocytic infiltration of the thecal layer of cells. Most commonly, evidence of abnormal thyroid function is detected, and, therefore, complete thyroid testing (with antibodies) is necessary in all patients with premature ovarian failure. The extensive polyglandular syndrome (autoimmune polyglandular syndrome) that includes hypoparathyroidism, adrenal 28 insufficiency, thyroiditis, and moniliasis, is rare; at least one gene mutation has been identified in this autosomal recessive disorder. In patients with adrenal insufficiency and ovarian failure, antibodies have been detected directed against P450scc, the cholesterol side-chain cleavage enzyme essential for 29 steroidogenesis. It is believed that antibodies can be directed against any of the vital enzymes involved in steroidogenesis. Other rare conditions associated with premature ovarian failure include myasthenia gravis, idiopathic thrombocytopenic purpura, rheumatoid arthritis, vitiligo, and autoimmune hemolytic anemia. Very rare pregnancies have been reported in women with ovarian failure and autoimmune disease, Ovulation has been restored temporarily with corticosteroid treatment, and at least one patient had a temporary spontaneous return of menstrual ovarian 31 activity. Because pregnancy is extremely unlikely, consideration should be given to donor oocytes. Galactosemia is a rare inherited autosomal recessive disorder of galactose metabolism due to a deficiency of galactose-1-phosphate uridyl transferase. The problem in patients with galactosemia is primarily gonadal; fewer oogonia may be the result of a direct toxic effect of galactose metabolites on germ cell 34 migration to the genital ridge. The final rare clinical situation associated with high gonadotropins despite the presence of ovarian follicles is that associated with specific enzymatic deficiencies. The 17-hydroxylase deficiency (P450c17) is present in both ovaries and the adrenal gland. A patient with a deficiency of 17-hydroxylase is readily detectable because she would present with absent secondary sexual development (sex steroids cannot be produced due to the enzyme block in the adrenal glands and the ovaries), and hypertension, hypokalemia, and high blood levels of progesterone. A deficiency in the aromatase enzymes is another rare cause of hypergonadotropic amenorrhea and a failure of pubertal development. The Need for Chromosome Evaluation All patients under the age of 30 who have been assigned the diagnosis of ovarian failure on the basis of elevated gonadotropins must have a karyotype determination.
