Avodart

By Y. Marlo. Trinity College, Hartford Connecticut.

Pregnant women High-dose therapy during the first 4 months of pregnancy has been associated with an increased incidence of birth defects (limb reductions 0.5 mg avodart medicine to reduce swelling, heart defects purchase avodart without prescription medications 247, masculinization of the female fetus) buy generic avodart 0.5mg on-line treatment brown recluse bite. Pharmacologic methods of contraception include oral contraceptives, etonogestrel implants, injectable medroxyprogesterone acetate, intrauterine devices, vaginal rings, and transdermal patches. Nonpharmacologic methods include surgical sterilization (tubal ligation, vasectomy), mechanical devices (condom, diaphragm, cervical cap), and avoiding intercourse during periods of fertility (calendar method, temperature method, cervical mucus method). Most of this chapter focuses on combination oral contraceptive pills—the most widely used reversible form of contraception. In preparing to study these agents and other forms of contraception, you should review Chapter 48, paying special attention to information on the menstrual cycle and the physiologic and pharmacologic effects of estrogens and progestins. Effectiveness of Birth Control Methods The effectiveness of a birth control method can be expressed as the percentage of unplanned pregnancies that occur while using the method. The least reliable methods include barrier methods, periodic abstinence, spermicides, and withdrawal. The perfect use figures represent pregnancy rates when a method of birth control is employed exactly as it should be (i. The higher pregnancy rates reported in the typical use column are largely an indication that methods of birth control are not always used when and as they should be. Selecting a Birth Control Method The method of contraception chosen most frequently is sterilization: female sterilization (tubal ligation) plus male sterilization (vasectomy) are selected by 37% of birth control users. The remaining methods—condoms, the sponge, diaphragm, cervical cap, spermicides, and periodic abstinence—must be used in a near-perfect fashion to afford any reasonable level of protection. Accordingly, women who consider the benefit/risk ratio unfavorable should be advised about alternative contraceptive techniques. Personal preference is a major factor in providing the motivation needed for consistent implementation of a birth control method. Because even the best form of contraception will be less effective if improperly practiced, the importance of personal preference cannot be overemphasized. Practitioners should take pains to educate patients about the contraceptive methods available so that selection and use can be based on understanding. If family planning goals have already been met, sterilization of either the male or female partner may be desirable. Conversely, when sexual activity is limited, use of a spermicide, condom, or diaphragm may be more appropriate. To help women select the birth control method that suits them best, Planned Parenthood has created a step-by-step computerized selection tool, accessible online at www. Secondary mechanisms include thickening of the cervical mucus (creating a barrier to the penetration of sperm) and alteration of the endometrium, making it less hospitable for implantation. Components Estrogens Only three estrogens are employed: ethinyl estradiol, mestranol, and estradiol valerate. A few older products use mestranol, which undergoes conversion to ethinyl estradiol in the body. One new product—Natazia—uses estradiol valerate, which undergoes conversion to estradiol in the body. Differences relate to side effects, especially thrombotic events, androgenic effects (acne, hirsutism, dyslipidemia), and hyperkalemia. Drospirenone, a fourth-generation progestin, has progestational, antiandrogen, and antialdosterone actions. The drug is a structural analog of spironolactone, a potassium-sparing diuretic that blocks receptors for aldosterone. Drospirenone reduces fluid retention by blocking aldosterone receptors, thereby preventing retention of sodium and water. Also, drospirenone can cause hyperkalemia (secondary to renal retention of potassium). Possible reasons include decreased blood levels of the hormones, sequestration in adipose tissue, and altered metabolism. Two newer progestins—drospirenone and desogestrel— appear to carry the greatest risk. Major factors that increase the risk for thromboembolism are heavy smoking, a history of thromboembolism, and thrombophilias. Additional risk factors include diabetes, hypertension, cerebrovascular disease, coronary artery disease, and surgery in which immobilization increases the risk for postoperative thrombosis. P a t i e n t E d u c a t i o n Thrombosis and Thromboembolism Women should be informed about the symptoms of thrombosis and thromboembolism (e. Women with a history of thrombosis should avoid estrogen/progestin products but can still use a progestin-only method. Options include the levonorgestrel intrauterine system [Mirena], medroxyprogesterone acetate injection [Depo- Provera], the etonogestrel subdermal implant [Nexplanon], and the “minipill”— all of which are discussed later. However, the absolute increase is low: only 8 cases per 100,000 women at age 20 years, rising to 80 cases per 100,000 women at age 40 years. These highly vascular, nonmalignant tumors are usually picked up as incidental findings on a computed tomography scan or magnetic resonance imaging. Effects that can result from an excess of estrogen include nausea, breast tenderness, and edema. During the first 3 months of use, spotting and breakthrough bleeding are common and usually resolve on their own. Hyperkalemia Drospirenone, a fourth-generation progestin, promotes renal retention of potassium and can thereby cause hyperkalemia. Accordingly, the drug is inappropriate for women with conditions that predispose to hyperkalemia (e. Furthermore, drospirenone should be used with caution in women taking other drugs that can elevate serum potassium. Glucose intolerance is most likely in patients who are already diabetic or have experienced gestational diabetes. As you can see, nearly all of these products contain the same estrogen: ethinyl estradiol. The purpose is to reduce the risk for fetal neural tube defects—anencephaly and spina bifida—if pregnancy should occur despite contraceptive use. As discussed in Chapter 65, neural tube defects can result if folic acid is low early in pregnancy. Natazia Natazia has two unique components: estradiol valerate and dienogest, a fourth- generation progestin. Estradiol valerate is a prodrug that undergoes rapid conversion to estradiol, the predominant endogenous estrogen. Dienogest, which is much like drospirenone (see previous discussion under “Components”), has strong progestational activity and antiandrogenic activity. However, in contrast to drospirenone, dienogest does not cause potassium retention, and hence there is no need to monitor potassium levels. In women who normally experience heavy or prolonged menstrual bleeding, Natazia can reduce blood loss.

This patient’s history of paroxys- mal hypertension with headaches order generic avodart online treatment gastritis, palpitations buy 0.5mg avodart with visa medications known to cause hair loss, and hyperadrenergic state (flush- ing purchase avodart with a visa medicine world nashua nh, dilat ed pupils, diaphoresis) suggest s the diagnosis of pheochromocytoma. Pheochromocytomas are catecholamine-producing tumors that arise from chro- maffin cells of the adrenal medulla. Other symptoms may include episodic anxiety, tremor, and orthost atic hypotension caused by volume contraction from pressure- induced nat riuresis. The diagnosis is established by measuring increased concentrations of catechol- amines or t heir met abolites in eit her urine or plasma. One-time measurement of plasma free metanephrines is a convenient and fairly sensit ive screening test. After the biochemical test s document the excess catechol- amines, t he next step is to locate the tumor for surgical removal. Approximately 90% of pheochromocytomas are in the adrenal gland, usually identified by com- puted tomography or magnetic resonance imaging. The treatment of choice for these tumors is surgical resection, but it is cr it ical t o reverse the acute and chronic effects of the excess catecholamines prior to exci- sion. Alpha-adrenergic blocking agents, such as phenoxybenzamine, an irrevers- ible, long-acting agent, started a week prior to surgery help to prevent hypertensive exacerbations, wh ich are especially wor r isome dur in g su r ger y. To expan d the com- monly seen contracted blood volume, a liberal salt diet is initiated. Sometimes, a beta-blocking agent is started, but only after alpha-blockade is established. T h e products of pheochromocytomas stimulate both the alpha- and beta-adrenergic receptors; thus, using a beta-blocker alone may worsen the hypertension because of unopposed alpha-adrenergic stimulation. Also, beta-blockade may result in acut e pulmonary edema, especially in t he presence of cardiomyopat hy secondary to chronic catecholamine exposure. Transfer the patient to the intensive care unit, obtain cardiac enzyme levels, and lower the blood pressures t o the 140/ 90 mm H g range. This man has a hypertensive urgency—elevated blood pressures without end-organ sympt oms. The appropriat e t reat ment is reinit iat ion of blood pres- sure medicat ions and reassessment in 24 t o 48 hours. Clonidine would not be a good maint enance t herapy given quest ions regarding his compliance wit h treatment and the risk of rebound hypertension. Elevated blood pressures without symptoms may occur acutely after sur- ger y, p ar t icu lar ly as a con sequ en ce of p ost op er at ive p ain. Blood pr essu r e m ed i- cat ion s are u su ally n ot in d icat ed wh en they are below the malign ant r an ge, but rather, pain control is the primary treatment. Lowering the blood pressure excessively can lead t o ort host at ic hypot ension when the pat ient get s out of bed. Elevated blood pressures may exacerbate congestive heart failure and must be treated. Generally, beta-blockers are avoided when patients are volume overloaded because beta-blockers decrease myocardial contractility. In general, blood pressure should not be acutely decreased (unless >220 mm Hg systolic) in an individual suspected of having an ischemic st roke because of t he concern for cerebral hypoperfusion and worsening brain ischemia. If t h rombolyt ic t herapy is considered, blood pressure sh ould be cont r olled t o < 185/ 100 m m H g, but this pat ient ’s sympt om du r at ion pr e- cludes that consideration. In contrast, patient s with intracerebral hemorrhage require urgent blood pressure decrease to values of 140 mm H g systolic or less to decrease the propagat ion of the hemorrhage. Ne ve rt h e le ss, m a rke d e le va t io n s in m e a n a rt e ria l pressure can exceed the ability of cerebral vessels to constrict, causing hyperperfusion, cerebral edema, and hypertensive encephalopathy.

Understand the management of acute atrial fibrillation with rapid ventricular response. Know the typical cardiac lesions of rheumatic heart disease and the physical fin d in gs in mit r al st en osis. T h e four major goals are: (1) hemodynamic stabilization, (2) rate control, (3) anticoagula- tion, and (4) possible conversion to sinus rhythm. O n ce the ventricular rate has been controlled, consideration can be given to reversing the underlying causes (eg, thyrotoxicosis, use of adrenergic stimulants, or worsen- ing heart failure) so that patients can undergo cardioversion to sinus rhythm. T his may occur spontaneously or after correction of underlying abnormalities, or it may require pharmacologic or electrical cardioversion. Rate control alone (ie, the use of agents to maintain a slow ventricular response rate) is often effective in managing the symptoms of atrial fibrillation, and it has been shown to be at least as effective as rhythm control for long-term outcomes. If pat ient s are unstable or persistently symptomatic, however, they may require effort s t o t erminat e t he at rial fibrillat ion, and rest ore sinus rhyt h m. Aft er car diover sion, the return of coordinated atrial contraction in the presence of an atrial throm- bus may result in clot embolization, leading to a cerebral infarction or other dis- tant ischemic event. Alternatively, low-risk patients can undergo transesophageal echocardiography to exclude the presence of an atrial appendage thrombus prior to cardioversion. Postcardioversion anticoagulation is still required for 4 weeks, becau se even t h ough the rh yt h m ret urn s t o sinu s, the at ria do n ot cont r act n or m ally for some t ime.

N ew oral anticoagulants such as dabigatran and rivaroxaban have been developed for use in atrial fibrillation, but the oral vitamin K antagonist warfarin remains the most widely used medication for this purpose. The major complication of warfarin therapy is bleeding as a consequence of excessive ant icoagulat ion. If clinically significant bleeding is present, warfarin toxicity can be rapidly reversed with administration of vit amin K and fresh frozen plasma to replace clotting factors and provide intravascular volume replacement.

Hence order avodart 0.5mg fast delivery symptoms panic attack, to help ensure pain relief in the future order avodart 0.5mg on-line treatment naive definition, they limit opioid use now and thus suffer needless pain buy avodart 0.5 mg online symptoms ectopic pregnancy. These patients should be reassured that, if tolerance does develop, efficacy can be restored by increasing the dosage; tolerance does not mean that efficacy is lost. This fear is based largely on the misconception that physical dependence (which eventually develops in all patients) equals addiction. Patients should be taught that physical dependence is not the same as addiction and that physical dependence itself is nothing to fear. In addition, they should be taught that the behavior pattern that constitutes addiction rarely develops in people who take opioids in a therapeutic setting. These patients should be reassured that, when used correctly, opioids are both safe and effective. With all of the adjuvants, the objective is to complement the effects of opioid and nonopioid analgesics. Furthermore, because the drugs we use as adjuvants were originally developed to treat disorders other than pain, the rationale for prescribing specific adjuvants should be explained. For example, when imipramine is prescribed, the patient should understand that the objective is to relieve neuropathic pain and not depression, the disorder for which this drug was originally developed. Under the standards, accountability for pain management is shifted from individual practitioners to the institution as a whole. Compliance is mandatory: health care organizations that fail to meet the standards will lose accreditation. Loss of accreditation would mean loss of insurance reimbursement and would disqualify teaching hospitals from offering training programs. It should be noted that the standards are not a guideline on how to treat specific kinds of pain. Rather, they focus on (1) the rights of patients to receive appropriate assessment and management of pain and (2) ways for institutions to establish a formalized, systematic approach to pain management that involves interdisciplinary teams whose members have clearly identified responsibilities. Specific provisions include the following: • Institutions must recognize assessment and management of pain as a right of all patients. Many of the drugs considered here are discussed in other chapters, so discussion in this chapter is limited to ophthalmologic applications. Drugs for Glaucoma Glaucoma refers to a group of diseases characterized by a decrease in peripheral vision secondary to optic nerve damage. The most common forms of glaucoma are primary open-angle glaucoma and acute angle-closure glaucoma. Of the 120,000 Americans blinded each year by glaucoma, 90% could have saved their sight with timely treatment. Unfortunately, many afflicted persons are unaware of their condition: of the 4 million Americans with glaucoma, only 50% are diagnosed. From there it circulates around the iris into the anterior chamber and then exits the anterior chamber through the trabecular meshwork and canal of Schlemm. Pathophysiology and Treatment Overview P a t i e n t E d u c a t i o n Glaucoma • It is important to take the prescribed medications according to schedule. If days are skipped or if prescriptions are not refilled, loss of vision may occur. Allow at least 15 minutes to elapse between administration and insertion of the lenses. Management is usually initiated by specialists; however, primary care providers often play a role in ongoing monitoring and follow-up of patients taking these medications. Other options —cholinergic drugs and carbonic anhydrase inhibitors—are considered second- line choices. All of the antiglaucoma drugs are available for topical administration, which is the preferred route. Because all of these drugs are applied topically, systemic effects are relatively uncommon. Nonetheless, serious systemic reactions can occur if sufficient absorption takes place. Angle-Closure Glaucoma Angle-closure glaucoma is precipitated by displacement of the iris such that it covers the trabecular meshwork, thereby preventing exit of aqueous humor from the anterior chamber. This disorder is referred to as angle-closure or narrow-angle glaucoma because the angle between the cornea and the iris is greatly reduced (Fig. A, Note that the angle between the iris and cornea is open in open-angle glaucoma, permitting unimpeded outflow of aqueous humor through the canal of Schlemm and trabecular meshwork. B, Note that the angle between the iris and cornea is constricted in angle-closure glaucoma, thereby blocking outflow of aqueous humor through the canal of Schlemm and trabecular meshwork. Treatment consists of drug therapy (to control the acute attack) followed by corrective surgery. A combination of drugs (osmotic agents, short-acting miotics, carbonic anhydrase inhibitors, topical beta-adrenergic blocking agents) is employed to suppress symptoms. Drugs Used to Treat Glaucoma Beta-Adrenergic Blocking Agents Actions and Use in Glaucoma Five beta blockers—betaxolol, carteolol, levobunolol, metipranolol, and timolol —are approved for use in glaucoma. These agents cause minimal disturbance of vision and are considered first-line drugs for glaucoma, although prostaglandin analogs are becoming favored. Beta blockers, in combination with other drugs, are also employed for emergency management of acute angle- closure glaucoma. Local effects are generally minimal, although patients commonly complain of transient ocular stinging. Beta blockers occasionally cause conjunctivitis, blurred vision, photophobia, and dry eyes. Constriction2 of the bronchi can occur with beta -selective antagonists as well as with1 “nonselective” beta-adrenergic blockers—although the risk is greatest with the nonselective agents. This drug is preferred to other beta blockers for patients with asthma or chronic obstructive pulmonary disease. Prostaglandin Analogs Four prostaglandin analogs are approved for topical therapy of glaucoma. P ro t o t y p e D r u g s Drugs for the Eye Beta Blockers Betaxolol (beta selective)1 Timolol (blocks beta and beta receptors)1 2 Alpha-Adrenergic Agonists Brimonidine Prostaglandin Analogs Latanoprost Angiogenesis Inhibitors Ranibizumab Latanoprost is generally well tolerated, and systemic reactions are rare. The most significant side effect is a harmless heightened brown pigmentation of the iris, which is most noticeable in patients whose irides are green-brown, yellow- brown, or blue/gray-brown. Heightened pigmentation stops progressing when latanoprost is discontinued but does not usually regress. Topical latanoprost may also increase pigmentation of the eyelid and may increase the length, thickness, and pigmentation of the eyelashes. Other side effects include blurred vision, burning, stinging, conjunctival hyperemia, and punctate keratopathy. Other Prostaglandin Analogs In addition to latanoprost, three other topical prostaglandins are approved for topical therapy of glaucoma.

If an infection is present avodart 0.5 mg mastercard medicine 50 years ago, it should be appro­ priately treated and the urinalysis repeated in 6 weeks best purchase avodart medicine zalim lotion. A serum creatinine should also be obtained to assess renal fnction order avodart once a day medications in mexico, with com­ parison to old records if available. I the laboratory evaluation reveals elevated cre­ atinine or red cell casts, workup should fcus on renal parenchymal disease and possible etiologies such as hypertension, diabetes, or autoimmune diseases. Patients with risk fctors should also undergo cytologic evalu­ ation of the urine to assess fr transitional cell carcinoma. Although voided urine cytology may not pick up low-grade carcinoma, it is firly reliable fr high-grade lesions, especially if repeated. Despite many studies comparing the radiographic methods, there are no evidence-based guide­ lines on which modality is most efcient. Choice of imaging modality should take into account any contraindications the patient may have including renal insuf­ fciency, contrast allergy, or pregnancy. The lower urinary tract should be examined fr transitional cell carcinoma by cystoscopy in all patients who are older than 35 years or who present with risk fctors fr lower urinary tract malignancies. In the absence of risk fctors in selected patients with a neative history, examination, labo­ ratory workup, and upper tract imaging, and those younger than 35 years, cystoscopy may be defrred or individualized at the discretion of the treating physician. However, if the patient develops gross hematuria, voiding difculties, pain, or any abnormal cytology, immediate urologic reevaluation and urologic consultation is warranted. Patients who develop hypertension, proteinuria, glomerular casts, or abnormal renal fnc­ tion should be refrred to a nephrologist fr consultation. Upon frther questioning he does reveal that 2 days ago he had a bladder catheterization to evaluate his postvoid residual. Counsel the patient on the high likelihood of gross hematuria afer a urologic procedure and that this will likely subside. Discuss with the patient the high likelihood of malignancy with gross hematuria especially given his age and past history and recommend imaging upper and lower urinary tracts. He states he has been evaluated by several other physicians who had done "several tests" that all came back negative. At this time, what would be the most appropriate imaging modality and management fr this patient? Order a combined renal ultrasound and retrograde pyelogram fr maxi­ mum visualization of upper urinary tract, along with an urgent urology referral. Order urine cytology and urine markers as these are the least invasive test of choice at this time. I is appropriate to discuss with the patient that his gross hematu­ ria, given his lack of risk fctors fr malignancy, is most likely caused by the recent bladder catheterization; however, as stated earlier, this is not a reason to dismiss frther evaluation. Certainly, if his gross hematuria continues afer several weeks, it would be imperative to conduct frther evaluation. This patient has two simultaneous contraindications to imaging modali­ ties prefrred in the workup of microscopic hematuria. For this reason, the next best imaging modality would have to be done, a renal ultrasound, which when combined with a retrograde pyelogram would provide maximum infrmation about the upper urinary tracts. Urine cytology and urine markers, although noninvasive, are not cur­ rently recommended in the routine evaluation of microscopic hematuria. If no source is fund on a thorough initial workup, patients should be fllowed fr at least 3 years to monitor fr an underlying condition. In every case of a first-time microscopic hematuria, a repeat urinalysis with microscopy is required at 6-week interval befre any other manage­ ment is done. Evaluation of asymptomatic microscopic hematuria in adults: the American Urological Association best practice policy-part I: defnition, detection, prevalence, and etiology. She also states that she is having difficulty concentrating at work and has been more irritable with her coworkers. The patient also notes that she has developed a persistent rash over her shins that has not improved with the use of topical steroid creams. All of her symptoms have come on gradually over the past fw months and continue to get worse. She is currently not sexually active and does not drink alcohol, smoke, or use any illicit drugs. Her eyes show evidence of exophthalmos and lid retraction bilaterally, although funduscopic examination is normal. Neck examination reveals symmetric thyroid enlargement, without any discrete palpa­ ble masses. Neurologic examination is normal except fr a fine resting tremor in her hands when she attempts to hold out her outstretched arms.

Her irr hert· bet may be a manifstton of atrial fbrillaton, which ocurs in appromately 10% of hyperthyroid patiets. Graves disese h a unique ophthalmopathy that may cau a prominent ephthamos (Figure lS-1). Graves disease commonly occurs in reproductive-age fmales and is much more common in women than men. However, these are only temporary measures used to give patients symptomatic relief The defnitive treatment is radioactive iodine, which destroys the thyroid gland. At least 40% of patents who receive radioactve iodine eventually become hypothyroid and will need thyroid hormone replacement. Radioactive iodine therapy is contraindicated in pregnant women, as the isotope can cross the placenta and cause ftal thyroid abla­ tion. Due to adverse efects on ftal development, methimazole is not used during frst trimester of pregnancy. Surgical removal of the thyroid gland is another option fr the treatment of Graves disease, but it is ofen reserved fr pregnant patients. Physical fndings include a rapid pulse rate and elevated blood pressure, with the systolic pressure increased to a greater extent than the diastolic pressure, creat­ ing widened pulse-pressure hypertension. Thyroid storm is an acute hypermetabolic state associated with the sudden release oflarge amounts ofthyroid hormone into circulaton. It occurs most ofen in patients with Graves disease, but can also occur in acute thyroiditis conditions. Examination may demonstrate tachycardia, elevated blood pressure, fever, and dysrhythmias. Thyroid storm is a medical emergency that requires prompt attention and reversal of the metabolic demands of acute hyperthyroidism. Pathogenesis Graves disease is the most common cause of hyperthyroidism and is more com­ monly fund in women. In addition to the usual fndings, approximately 50% of patents with Graves disease also have exophthalmos. The second most common cause of hyperthyroidism is an autonomous thyroid nodule that secretes thyroxine. Hyperthyroidism can also be caused by the acute release of thyroid hormone in the early stages of thy­ roiditis. In such cases, symptoms are generally transient and resolve within weeks of onset.

Left untreated generic avodart 0.5mg otc treatment integrity checklist, peripartum depression lasts for months and is likely to become worse as time passes buy avodart without prescription medicine 0829085. The condition is detrimental to the mother purchase 0.5 mg avodart with mastercard symptoms white tongue, and it can adversely affect the child, preventing secure attachment and impairing cognitive, emotional, and behavioral development. True peripartum depression is an episode of major depression that starts in the weeks before or just after giving birth. Otherwise, the diagnostic criteria are the same as for all other episodes of major depression. However, most clinicians who study the disorder use a different criterion: to them, depression is considered postpartum if it begins within 3 months of delivery—not just within 4 weeks. In addition to a prior history of the disorder, risk factors include a history of depression unrelated to childbirth, history of premenstrual dysphoric disorder (i. The underlying cause of peripartum depression is unknown, but several factors are thought to contribute. Heading the list is the sharp drop in estrogen and progesterone levels that occurs after delivery. Caring for a baby, who needs round-the-clock attention and feeding, exacerbates tiredness and exhaustion. Feelings of loss are common: women experience loss of freedom, loss of control, and even loss of identity. Stress increases substantially, owing to increased workload and responsibilities, coupled with feelings of self-doubt and inadequacy, and compounded by a self-imposed (albeit highly unrealistic) expectation to be a “perfect” parent. Thyroid insufficiency may also contribute: Levels of thyroid hormone often decline after delivery, causing symptoms that can mimic depression. Accordingly, thyroid levels should be checked and, if indicated, replacement therapy should be implemented. Screening for peripartum depression should be contemplated in all women, although evidence is lacking regarding universal screening. Screening can be accomplished with a quick test: the Edinburgh Postnatal Depression Scale. Treatment of peripartum depression is much like treatment of major depression unrelated to pregnancy. The principal treatment modalities are psychotherapy and antidepressant drugs, both of which can be effective. Although antidepressants are clearly appropriate, there are few published data to guide selection. However, if a woman has responded to an antidepressant from a different class in the past, that drug should be tried first. To minimize side effects, dosage should be low initially (50% of the usual starting dosage) and then gradually increased. To reduce the risk for relapse, treatment should continue for at least 6 months after symptoms have resolved. Unfortunately, even then the relapse rate is high: between 50% and 85% of patients experience at least one more depressive episode. All of these drugs can be detected in breast milk—but levels of some are lower (safer) than levels of others. Studies show that drug activity in breastfed infants is extremely low, and no adverse reactions have been observed. Infants of breastfeeding mothers on antidepressants should be monitored closely for these side effects. Somatic (Nondrug) Therapies for Depression Nondrug therapies are reserved for patients with severe depression that has not responded to drugs or psychotherapy. This procedure is safe and effective, and benefits develop more rapidly than with drugs or psychotherapy. A single treatment consists of delivering an electrical shock to the scalp that is sufficient to induce a generalized seizure lasting 20 to 30 seconds. Success requires a series of these treatments, typically 2 to 3 per week for a total of 6 to 12 treatments. Before the delivery of electroshock, patients are treated with two drugs: a short-acting neuromuscular blocker (succinylcholine) and a short-acting intravenous anesthetic (e. The neuromuscular blocker prevents shock-induced seizure movements, which are both hazardous and unnecessary for a therapeutic response. Accordingly, some patients are now given “maintenance” treatments, at weekly or monthly intervals. The principal adverse effect is amnesia, primarily for events immediately surrounding treatment. However, patients may also experience some loss of older memories, but these usually return within 6 months. Minor adverse effects, which occur immediately after treatment, include nausea, headache, confusion, and muscle discomfort. The magnetic fields induce electrical currents in the brain, which in turn cause neuronal depolarization and other changes in brain activity. A full course of treatment consists of daily 40-minute sessions for 6 weeks or so. Newer small studies show possible promise in patients with severe, refractory depression. Light can be beneficial alone and can enhance the response to antidepressant drugs. The mainstays of therapy are lithium and divalproex sodium (valproate), drugs that can stabilize mood. Many patients also receive an antipsychotic agent, and some may require an antidepressant. Typically, patients experience alternating episodes in which mood is abnormally elevated or abnormally depressed—separated by periods in which mood is relatively normal. Symptoms usually begin in adolescence or early adulthood but can occur before adolescence or as late as the fifth decade of life. In the absence of treatment, episodes of mania or depression generally persist for several months. Pure Manic Episode (Euphoric Mania) Manic episodes are characterized by persistently heightened, expansive, or irritable mood—typically associated with hyperactivity, excessive enthusiasm, and flight of ideas. Manic individuals display overactivity at work and at play and have a reduced need for sleep. Extreme self-confidence, grandiose ideas, and delusions of self- importance are common. In severe cases, symptoms may resemble those of paranoid schizophrenia (hallucinations, delusions, bizarre behavior). However, symptoms are not severe enough to cause marked impairment in social or occupational functioning, or to require hospitalization. Associated symptoms include disruption of sleeping and eating patterns; difficulty concentrating; feelings of guilt, worthlessness, and helplessness; and thoughts of death and suicide.
