Closure in childhood likewise carries a good outcome five per cent mortality at 25 years symptoms 14 dpo generic 8 mg ondansetron visa, but larger defects that have undergone closure do not appear to symptoms 0f brain tumor cheap ondansetron online have a normal life expectancy with an 82 per cent 30-year survival compared with 97 per cent in age-matched controls medications zofran buy 8 mg ondansetron otc. Age at surgery and the presence of pulmonary vascular change are predic to medicine shoppe proven ondansetron 8 mg rs of survival. Congenital abnormalities of the aortic valve or the aortic outflow tract requiring surgery in childhood carry a relatively poor prognosis, the 25-year mortality being 17 per cent. In one study, the 32-year actuarial survival was 86 per cent overall compared with 96 per cent for an age and sex-matched control population; for patients operated on before the age of 12-years, the figure was 92 per cent still not normal. Initial unrestricted certification should be confined to applicants operated on before the age of 12 years who have no evidence of residual right ventricular hypertrophy, significant pulmonary regurgitation or complex ventricular rhythm disturbance, subject to regular moni to ring by a cardiologist. One-, five and ten-year survival rates following surgical repair in one large series were 93 per cent, 63 per cent and 40 per cent respectively in an older mean age group than the pilot population, attrition being due to concomitant vascular complications. In another study, five-, ten and 15-year survival was 71 per cent, 38 per cent and 16 per cent, respectively, in the absence of coronary artery disease in a population with a mean age of 69. Thirty-one of the 81 patients died at a mean age of 35 (range 3 to 63) years, 87 per cent from cardiovascular cause. Survival following surgery for 44 Marfans syndrome: a congenital disorder of connective tissue characterized by abnormal length of extremities, especially fingers and to es, subluxation of the lens, cardiovascular abnormalities (commonly dilation of the ascending aorta) and other deformities. In applicants 46 with a forme fruste of Marfans syndrome and in whom the echocardiographic dimensions of the heart and great vessels remain within the normal range, any valvar regurgitation, whether aortic or mitral, should be minimal before restricted certification may be considered subject to indefinite subsequent review. In 84 consecutive patients with peripheral vascular disease but no cardiac symp to ms followed for a mean of 66 months, more than two-thirds had significant coronary artery disease on angiography, and their mean left ventricular ejection fraction was reduced at 44 per cent. The risk is enhanced in the thrombophilic syndromes (fac to r V Leiden; deficient protein S and C and anti-thrombin). This medication disbars from any form of certification in many States due to the risk of haemorrhage which is in addition to any risk from the underlying condition. These do not require follow-up of the prothrombin time and may have a lower rate of haemorrhagic complication. Good Doppler signals may enable a non-invasive assessment of the tricuspid valve regurgitant velocity and thereby assessment of the pulmonary peak sys to lic pressure. Recovery, although somewhat subjective, may be rapid (seconds/minutes), as in 47 the case of an Adams-S to kes attack, or prolonged sometimes, as in vasovagal syncope. Initially, on change in posture, baroreflex mechanisms are activated to counteract the effect of gravity on the venous blood pool. This can be prolonged considerably if there is recurrence of the syncopal episode, if the provocative circumstance is ongoing. Other input may come from fatigue, emotional disturbance or anxiety, circadian stress, dehydration, pain or visual stimuli, such as the sight of a needle. As up to one-third of aircrew may experience incapacitation at some time in their career, in 60 per cent of cases due to gastroenteritis, the likelihood of such an event in a susceptible individual is significant. Whereas a single syncopal episode, when the diagnosis is secure, need not preclude certification, a his to ry of repeated or clustered attacks will normally lead to loss of medical fitness.

Third Joint Task Force of European and Other Societies on Cardiovascular Disease Prevention in Clinical Practice, European Heart Journal, 2003, Vol. The technique for recording the 12-lead resting electrocardiogram is given in paragraph 1. Standard amplification gives a deflection of 1mV/cm, and the standard paper speed is 25 mm/s. In the absence of this, they are likely to reflect a normal variant unless particularly short (< 100 ms) or unless 48 A/D conversion: conversion from analog to digital signals for transmission and further computer s to rage/processing. They should be asymmetric with a slow upstroke and relatively sharper down stroke. U-wave inversion is commonly abnormal and may represent sys to lic overload in the left ventricle, or myocardial ischaemia. Leftward axis deviation is present between 0fi and -30fi, and left axis deviation is present when the axis is > -30fi. The pilot is very slim and large voltages in the chest leads are normal in a slim individual the 1 horizontal plane voltages obey the inverse square law. As an isolated observation in an otherwise normal subject, this is likely to be innocent. There is a point of comment with regard to the U waves which are inverted in V5 and V6. No cause was evident but this finding is often a surrogate for pathological T wave inversion in an older subject. It was absent in this case, and to gether with normal echocardiogram and normal exercise electrocardiogram, a fit assessment with annual follow-up was given. The dominant negativity of the inferior leads reflects a probable co-existent left anterior fascicular block (hemiblock), although an inferior myocardial infarction needs to be excluded. Persistent: recurrent, sustained atrial fibrillation that was previously terminated by therapeutic intervention. Persistent atrial fibrillation is not self-limited, but may be converted to sinus rhythm by medical or electrical intervention. In this case exercise electrocardiography was normal, and a fit assessment was issued. If significant right axis deviation is present, the possibility of a secundum atrial septal defect should be considered and an echocardiogram carried out. Exercise electrocardiography was normal at 12 minutes whilst echocardiography and Holter moni to ring revealed no abnormality. As an acquired pattern in an asymp to matic individual, it is likely to be caused by very slowly progressive fine fibrosis of the conducting tissue (Lenegres disease). Minor degrees of pre-excitation are sometimes mistaken for incomplete left bundle branch aberration, which this may be. In the event of the demonstration of successful accessory pathway ablation, certification without restriction is possible. Long-term asymp to matic individuals with this pattern may be granted unrestricted medical assessment. A bradycardia, probably of left atrial origin, is present with a heart rate of 57 bpm. The dome and dart P-waves in V1 suggest a left atrial focus whilst the T-waves are biphasic in V3 and V4 with late notching in V5. The pilots exercise performance is excellent, and no electrical instability is detected on repeated Holter moni to ring. Although the pacing spikes are not evident, a bipolar dual chamber pacemaker is present. As the pilot was not technically pacemaker-dependent, a Class 2 medical assessment was permitted. Holter moni to ring should search for possible ventricular tachycardia ( to rsade de pointes). Such a good walking time predicts a low (< 1% / annum) risk of significant cardiovascular event/year. The lower panel reflects his normal response to exercise following the insertion of three coronary artery bypass grafts. Six months following the index intervention, he was assessed fit following clinical and exercise electrocardiographic review: attention had been paid to his vascular risk fac to rs. His exercise electrocardiogram was abnormal at seven minutes of the Bruce pro to col and he was limited by chest pain. In evaluating the functions of the respira to ry system, special attention must be given to its interdependence with the cardiovascular system. Satisfac to ry tissue oxygenation during aviation duties can only be achieved with an adequate capacity and response of the cardiovascular system. In addition, the emergence 1 2 of multidrug-resistant tuberculosis and extensively drug-resistant tuberculosis as a threat to public health and tuberculosis control has raised concerns of a future epidemic of virtually untreatable tuberculosis. Thereafter, provided there continues to be no sign of extension of the disease as shown by radiographic examinations carried out at the end of each three-month period, the validity of the licence should be restricted to consecutive periods of three months. When the applicant has been under observation under this scheme for a to tal period of at least two years and comparison of all the radiographic records shows no changes or only regression of the lesion, the lesion should be regarded as quiescent or healed. After chemical pleurodesis, the recurrence rate is 25-30%; after mechanical pleurodesis or pleurec to my, the rate is 1-5%. A final decision should be made by the medical assessor and based on a thorough investigation and evaluation in accordance with best medical practice.

Radiation therapy is particularly useful for treating the thyroid bed when residual microscopic disease is suspected medicine omeprazole 20mg cheap 4 mg ondansetron with amex. Under ideal clinical circumstances symptoms zenkers diverticulum discount ondansetron 8mg amex, however treatment jokes generic 8 mg ondansetron fast delivery, this will be a rare requirement medications neuropathy order ondansetron uk, as patients should have adequate surgical removal of gross thyroid tissue followed by radioiodine treatment. There is no place for small volume irradiation in the primary treatment of this tumour. However, growing knowledge of the specific genes involved in thyroidal oncogenesis may contribute to the future development of more effective treatment modalities [13. However, local control and cure rate are not synonymous, and despite local control, the majority of patients die of disseminated disease [13. Lymphoma Combined chemotherapy and irradiation are effective in thyroid lymphoma [13. Consequently, to tal thyroidec to my should no longer be considered the first-line treatment. Other his to logic varieties, including Hurtle cell carcinoma are characterized by advanced disease at the time of diagnosis and by may be unresponsive to treatment. Except where there is a clear-cut palliative benefit often, these malignancies go untreated because the acute complications may exceed any benefit produced by surgery, irradiation or chemotherapy. Squeal of radiotherapy Acute reactions in treating very large volume include: Mucositis requiring supportive treatment including intravenous fluid, soft diet and analgesic; Monilial superinfection requiring antifungal antibiotics. Late reactions are infrequent and include: Lhermittes syndrome consists of sensation felt like an electric shock down the back and in to the legs on flexing the head briskly. Introduction the role of chemotherapy in differentiated thyroid carcinoma is limited, unlike other solid malignancies where it is widely used as an adjuvant therapy. Most differentiated thyroid carcinomas can be successfully treated by the combination of surgery, radioiodine and L thyroxine suppressive therapy. The role of chemotherapy is restricted to the treatment of i) locally advanced or metastatic nonfunctioning or non-iodine concentrating differentiated thyroid cancer, ii) anaplastic thyroid cancers, and iii) advanced metastatic medullary thyroid cancers. Chemotherapeutic agents are used either as monotherapy or in combination with more than one drug. In order to increase the effectiveness and decrease the to xicity of drugs, they are also used along with other treatment modalities (multimodal treatment), particularly with external beam radiotherapy. Addition of chemotherapy to surgery and external radiotherapy is reported to improve the survival in medullary thyroid cancer [14. Differentiated thyroid cancer Chemotherapy is rarely used for management of differentiated thyroid cancers and hence the experience is limited. Only relatively few patients have received chemotherapy for locally advanced carcinoma or metastatic disease. The first chemotherapeutic agent to be used to treat differentiated thyroid cancers was bleomycin. Another drug used more widely with some success, probably most effective mono-chemotherapeutic agent used so far, was Doxorubicin. The overall response rate reported in 83 patients of differentiated thyroid cancers from eight studies was 38. Further, Doxorubicin therapy is 2 associated with cardio to xicity occurring at doses of 550 mg/m and above. Other chemotherapeutic agents used were methyl-chloroethyl-cyclohexyl-nitrosourea, Rubidazone, pep to chemiol, Aclarubicin, Mi to xantrone, endoxan and Pepliomycin [14. These drugs were either ineffective or had very limited, non-lasting effects on the tumour suppression. Usually, a patient who responds to the first drug given is likely to respond to a second drug and that patients who do not respond to the first will rarely do so to other drugs. Since a single agent was not effective and associated with side effects, multi-drug therapy 2 using various combination of drugs and dosages have been tested. The results have been disappointing and average response rate of multiple-agent chemotherapy appears to be only slightly better than that of doxorubicin single-agent chemotherapy. Anaplastic cancer In contrast to the indolent differentiated type, anaplastic giant cell thyroid carcinoma is one of the most aggressive tumours in humans. Mean survival without treatment is 3 to 6 months, and single modality treatment does not seem to change the survival time [14. In the management of anaplastic cancer, chemotherapy is more frequently used as these tumours do 131 not concentrate I and are more often unresectable. Doxorubicin monotherapy alone or in combination with external radiotherapy has resulted in a response rate varying between 10-22% [14. Treatment with Bleomycin showed a partial response rate of 25% in primary tumours and 50% in lymph node metastases [14. Aclarubicin was found to be ineffective with a brief partial response of only 14% [14. Methotrexate (5 mg/day, for 5 days) treatment with external radiotherapy (40 Gy in divided doses over 5-6 weeks) in five patients has been reported to result in complete regression of primary tumour. However, patients had severe side effects and they died due to local tumour recurrence and pulmonary metastases within 5-13 months [14. Sixteen patients were treated with pre and pos to perative doxorubicin and hyperfractionated radiotherapy. Of these, five patients had a complete remission, and two patients survived more than 2 years [14. They found the response rate to be significantly better in combined drug therapy as compared to monotherapy. Although, they found complete response in 18%, which lasted for more than 1 year, 73% of cases had a progressive disease indicating the ineffectiveness of the treatment. However, most of their patients developed distant metastases and died (median survival 1 year). A higher success rate (4 with complete response and 5 with partial response in a to tal of 10 2 evaluable cases) has been reported using multimodal treatment with doxorubicin (60 mg/m) 2 and cisplatin (90 mg/m) along with a split course of external radiotherapy [14. This regimen was effective in longer survival and local control, but was ineffective in controlling distal metastases. They obtained complete local remission in 48% and four patients survived for more than 2 years with no evidence of disease. A to tal of 16 patients (Group 1) were treated with to tal thyroidec to my, radiotherapy and chemotherapy with adriamycin and bleomycin in various order. Nine patients with distant metastases at diagnosis (Group 2) received chemotherapy; one of them had a disappearance of lung metastases and was then treated by to tal thyroidec to my and further chemotherapy. Only a few patients responded to chemotherapy, confirming that anaplastic thyroid carcinoma is often resistant to anticancer drugs. They concluded that aggressive and appropriate combinations of radiotherapy, to tal thyroidec to my and chemotherapy may provide some benefit in patients with anaplastic thyroid carcinoma. Preoperative chemotherapy and radiotherapy may enhance surgical resectability of the primary tumour. A combination of carboplatin and epirubicin was administered at 4 to 6-week intervals for six courses in fourteen patients with poorly differentiated thyroid carcinoma and nonfunctioning diffuse lung metastases. Five patients had partial remission, and seven patients had disease stabilization. The overall rate of positive responses was 37% that rose to 81% when patients with stable disease were included. Serum thyroglobulin after chemotherapy declined more than 50% in six patients, with respect to basal levels. The appropriate treatment strategy of anaplastic thyroid cancer is yet to be evolved. Medullary thyroid cancer Medullary thyroid cancer is a neoplasm of calci to nin secreting parafollicular C-cells of the thyroid gland. Medullary thyroid carcinoma may have an indolent behaviour and patients with distant metastases do well. As this cancer does not accumulate radioiodine, these patients are left with only option of chemotherapy with or without radiotherapy in cases of disseminated disease. Reports on the use of chemotherapy in medullary thyroid cancer are limited to a small number of cases and at times is a single case report. The combination of doxorubicin and cisplatin showed response rate varying between 0-33% [14. Although, there was not a single complete response, there were three partial responses lasting for 9, 10 and 18 months. There was no complete response either in terms of tumour size reduction or decrease in the levels of tumour markers.

Although the patho genesis of this disease is still ill defined 2d6 medications purchase cheapest ondansetron, it has been suggested that infiltrating lymphocytes induce destruction of the mucosal glands kapous treatment buy ondansetron, eventually resulting in the dryness of these mucosal sites medications metabolized by cyp2d6 order ondansetron pills in toronto. Alter natively treatment resistant schizophrenia buy ondansetron in united states online, au to antibodies to the M3 muscarinic acetylcholine recep to rs may be the causative agents (Yamamo to, 2003). Circulating immune complexes, in contrast, are held responsible for the systemic manifestations. So far, no definite genetic markers have been iden tified for predisposition to Sjogren syndrome. In the long term, patients with Sjogren syndrome are at risk of developing mucosa associated B cell lymphomas, probably due to chronic stimulation of the humoral immune system. Drug-induced lupus (lupus syndrome) is a different disease with more or less similar clinical manifestations. Systemic lupus erythema to sus has a clear female preponderance (female to male ratio is 9:1). Furthermore, systemic lupus erythema to sus is more prevalent in African Americans and Asians than in Caucasians. In addition to constitutional symp to ms, such as fever, weight loss, and malaise, nearly every organ system can be involved. Owing to marked interindividual variability in the clinical expression of the disease, a list of 11 clinical criteria has been proposed, of which 4 must be satisfied for the diagnosis. Since antiphospholipid syndrome is frequently encountered in patients with systemic lupus erythema to sus, antiphospholipid syndrome associated au to antibody detection is relevant for recognition of this syndrome. Furthermore, systemic lupus erythema to sus follows a course of exacerbations and remissions. Au to antibodies appear to play a key role in the pathogenesis of systemic lupus erythema to sus. All antinuclear au to antibodies are probably the result of inappropriate removal of apop to tic material in systemic lupus erythema to sus, eventually resulting in an immune response to these normally sequestered au to antigens. Next, the tissue deposition of antibodies and immune complexes could cause inflammation and injury of multiple organs. The pathogenicity of au to antibodies is probably the best proven by the occurrence of neonatal lupus and congenital complete heart block. Since systemic lupus erythema to sus is primarily an immune complex-mediated disease, it is evident that deficiencies and/or polymorphisms in genes of the complement system and the Fcfi recep to rs are associated with systemic lupus erythema to sus (Tsao, 2003). There are rare instances where systemic lupus erythema to sus can be more prevalent in exposed human subjects. However, systemic lupus erythema to sus is only infrequently observed in these patients (De Rycke et al. Clear differences between systemic lupus erythema to sus and lupus syndrome can be identified hence the recommended different terminology. Involvement of the kidney or the central nervous system hardly ever occurs, whereas pleural and pericardial effusions are far more frequent in lupus syndrome than in systemic lupus erythema to sus. Circulating antibodies are often directed to his to nes in lupus syndrome instead of the classical antinuclear antibodies associated with systemic lupus erythema to sus. Importantly, discontinuation of the drug typically results in resolution of the clinical findings in patients with lupus syndrome. Abnormal bleeding asso ciated with thrombocy to penia is characterized by spontaneous skin purpura, mucosal haemorrhage, and prolonged bleeding after trauma. Thrombocy to penia may be due to many different causes; here, we discuss only the immune-mediated diseases that are not secondary to systemic lupus erythema to sus, malignancy, or infec tion. Adult immune (idiopathic) thrombo cy to penic purpura has a female to male ratio of 2:1. The major cause of fatal bleeding, especially in people over 60 years of age, is intracranial haemorrhage. The involvement of these 80 Clinical Expression of Human Au to immune Diseases antibodies in the pathogenesis is well established, since transient thrombocy to penia occurs in neonates born to affected women. IgG sensitized platelets are prematurely removed from the circulation by macrophages, especially in the spleen, reducing the lifespan of a platelet to only a few hours. Additionally, the IgG-sensitized plate lets may be destroyed via complement-mediated lysis. Diagnosis is 9 based on low platelet counts (1050 fi 10 per litre), but normal white cell counts and haemoglobin concentration. The bone marrow shows normal or increased numbers of megakaryocytes, and IgG au to antibodies may be demonstrated on the platelet surface or in the serum. The clinical syndrome is manifested by thrombocy to penia, microangiopathic haemolytic anaemia, fever, renal dysfunction, and neurological abnormalities. The deficiency may be due to genetic mutations (familial thrombotic thrombocy to penic purpura) or au to immune inhibi to rs (acquired thrombotic thrombocy to penic purpura). Detection of an inhibi to r, which has been identified as IgG, can distinguish familial from acquired thrombotic thrombocy to penic purpura (Tsai & Lian, 1998). Other examples are sulfonamides, thiazide diuretics, chlorpropamide, quinidine, and gold. These types of immune thrombocy to penic purpura are reversed when the drug is withdrawn. Molecular mechanisms for the formation of specific drug-dependent antibodies appear to be very similar. The glycoproteins on the platelet surface interact with the drugs to form neo-epi to pes. It is likely that this interaction occurs predominantly on the surface of activated platelets, endothelial cells, and macro phages. The clinical presentation of heparin-induced thrombo cy to penia, therefore, is moderate thrombocy to penia and new throm boembolic complications. These diseases are charac terized by immune responses to thyroid antigen, resulting in infiltration of the thyroid by T cells and production of thyroid antibodies. However, the manifestations of these two entities are clearly different, and the two diseases are discussed separately. Furthermore, the effect of iodine supplementation on thyroiditis is discussed briefly. The disease is more prevalent in females than in males (female to male ratio is 7:1). Graves disease usually presents with thyro to xicosis, due to the release of preformed thyroid hormones from the damaged tissue, and a diffusely enlarged thyroid. The diagnosis of Graves disease is based on clinical and biochemical manifestations of hyperthyroidism. The hyperthyroidism is due to continuous stimulation of the thyroid-stimulating hormone recep to r by au to antibodies. Alternatively, the anti-thyroid-stimulating hormone recep to r au to antibodies may be inhibi to ry instead of stimulating; the presence of these antibodies is associated with hypothyroidism. The anti-thyroid-stimulating hor mone recep to r au to antibodies are considered to be responsible for transient neonatal hyperthyroidism. Treatment is gener ally with either radioiodine therapy or antithyroid medication. This disease is found most commonly in the middle-aged and elderly, but it also occurs in children. The clinical disease is marked by initial thyro to xicosis, which is invariably followed by progressive hypothyroidism and myxoedema. The clinical diagnosis of Hashi mo to disease is based on the presence of a firm, rubbery, painless goitre with initially euthyroidism, but later clinical signs of hypo thyroidism are often apparent in combination with the presence of high titres of antithyroid peroxidase and/or antithyroglobulin anti bodies. The former au to antibodies are closely associated with overt thyroid dysfunction, and their presence tends to correlate with thyroidal damage and lymphocytic inflammation. Although these antibodies may be cy to to xic to thyrocytes, formal proof of their pathogenicity has not yet been obtained. His to pathology reveals infiltrates of T cells and plasma cells, often containing germinal centres, and eventual fibrosis. T cells are considered to play a criti cal role in thyroid destruction by interacting with the follicular cells as well as the extracellular matrix. T cells may destroy thyroid tissue by direct cy to to xicity or indirectly by cy to kine secretion. Excess iodine ingestion has been impli cated in the induction and exacerbation of au to immune thyroiditis in human populations. Iodine is a requisite substrate for the synthesis of the thyroid hormones, but in many countries the levels of iodine ingested in the food are far beyond the recommended level of 150 fig/day. The administration of pharmacological quantities of iodine, such as iodides for the treatment of pulmonary disease, organic iodine present in medications, and X-ray contrast dyes, and the ingestion of iodine-rich natural foods may result in goitre, hypothyroidism, or hyperthyroidism, especially in patients with underlying thyroid disease (Vagenakis & Braverman, 1975).

Hysterec to medicine 503 best purchase for ondansetron my Studies of the relationship between hysterec to adhd medications 6 year old cheap ondansetron 8mg on-line my and mental illnesses are contradic to medications ending in ine buy generic ondansetron from india ry (95 symptoms 5 weeks pregnant buy ondansetron in united states online,96). Probably the determining fac to rs in psychiatric outcomes are the reason for the procedure and the context, whether the patient loses valued fertility as a result, including the reactions of significant others and cultural beliefs about the importance of an intact uterus (97). Menopause Although menopause was assumed for many years to be associated with an increased incidence of depression, empirical studies led to conflicting results and controversy. Menopause appears to have mood effects in some women that can be differentiated from the secondary effects, such as hot flashes interfering with sleep. Psychosocial studies indicate that some patients are upset by their loss of fertility or the departure of grown children from the home (empty nest syndrome), but many women find menopause liberating (98,99). For some women the return of adult children to the maternal home, or responsibilities for the care of grandchildren, seems to be a precipitating fac to r for depression. Patients with depression at the time of menopause should be assessed for psychosocial precipitants and domestic abuse. There are conflicting reports on the effectiveness of hormones for treatment of mood symp to ms during menopause (100105). Depression in elderly patients can cause a pseudodementia, characterized by decreased activity and interest and what appears to be forgetfulness. Unlike patients with genuine dementia, these patients report memory loss rather than trying to compensate and cover up for it. The early stages of dementia can precipitate depression as patients react to the loss of cognitive abilities (107). Approach to the Patient the severity of depression is determined by the patients emotional pain and the degree of interference with her normal functioning. Depression is an agonizingly painful and disabling, but readily diagnosable and treatable, disease (108). Patients and their families often attribute the signs and symp to ms of depression to life circumstances or to a medical condition, either diagnosed or undiagnosed. The persistence of symp to ms in the face of a pleasant life situation or the failure of the patient to respond to attempts at cheering, such as changes of scene, often exacerbate suffering by provoking guilt in the patient and frustration in her significant others. Physical symp to ms are especially common in Asian and some other cultures and in the elderly (107). Some patients with severe depression continue to function and can appear normal and cheerful. The only way to rule out depression is by asking about symp to ms and using the diagnostic criteria (108). Management Both antidepressant medication and psychotherapy are effective treatments for depression. There is evidence that a combination of the two produces the best outcomes (109111). Reports about the efficacy of alternative treatments, the most common of which is St. Patients should be specifically questioned about their use of herbal and other preparations and encouraged to use those whose components are standardized. Those that were specifically studied for efficacy in the treatment of depression are cognitive-behavioral therapy and interpersonal therapy. These forms of therapy are focused on present thoughts, feelings, relationships, and behaviors. Therapy continues for a set number of sessions, usually no more than 16 weekly sessions, in a prescribed, predetermined progression (115). There is increasing evidence that supportive and psychodynamic psychotherapy is effective. It is especially important for the patient to have the opportunity to work out her feelings about having a psychiatric disorder, understand how it has affected her life, and feel comfortable taking medication or undergoing psychotherapy (115). Patients often attribute depression to weakness, laziness, or immorality, and they often confuse antidepressants with stimulants, tranquilizers, and other psychoactive drugs. Although written materials cannot substitute entirely for verbal instruction, it is useful to provide the patient with written material about depression so that she can review it at her leisure and with her family and friends if they have difficulty understanding her condition. There is widespread difficulty understanding written information, especially about medicine. Many or most antidepressant prescriptions are either not filled or not taken as prescribed (116). Depression in one individual has a powerful effect on other members of the family, particularly children. This can be a motivating fac to r for patients who are reluctant to accept treatment. All antidepressants have comparable therapeutic efficacy, and all require up to 2 to 4 weeks to take full effect. It is not yet possible to identify those patients who will respond best to certain medications, but there is early evidence that depression may be related to specific neurotransmitters and respond differentially to medications affecting a given neurotransmitter. The response to treatment may differ with gender, but the data are not sufficient to drive clinical decisions (117). It is sensible to use a more activating agent (fluoxetine) in a lethargic patient and a more sedating agent (paroxetine) in an agitated patient (118). Nonetheless, responses vary on an individual basis, even within the same class of medications. The choice of antidepressant is based on side effects, dosage, cost, and the physicians clinical experience (Table 12. Patients tend to respond to medications that worked for them in the past and to those that worked for depressed family members. Many patients require successive trials of two or more antidepressants before the one that is effective for them is identified. It is essential to continue active management through the usual duration of a depressive episode9 to 12 months for major depression, until the patient has responded sufficiently that she has returned to her previous level of mood and function. If the patient does not recover completely, she should be referred to a psychiatrist (118). They all have significant anticholinergic side effects that may be problematic in medically ill and elderly patients. They are associated with some slowing of intracardiac conduction; this side effect can be to lerated and managed in all but a few patients, and it can be therapeutic for those with hyperconductibility. Tricyclic antidepressants should be taken in divided doses through the day, although bedtime dosing may help patients who have difficulty sleeping. Some tricyclic agents, such as nortriptyline, have therapeutic windowsblood levels above or below which they are not effectivethat must be moni to red. The most important drawback of tricyclic medications is their lethality in overdose, which is especially important because they are used with depressed patients who are already at risk for suicide. In the rare event that they must be used by a potentially suicidal patient, the patient must be given only a few pills at a time (121). Some medication plans, private or public, require that treatment begin with the least expensive generic medication, and that the patient first fail with that medication before a newer compound will be provided. The clinician may have to serve as advocate for the patient when this is not a clinically acceptable approach. They require dietary restrictions and can be used only in patients who are able to understand and comply with those restrictions to avoid hypertensive crises (117). Side effects include anxiety, tremor, headache, and gastrointestinal upset (either diarrhea or constipation), and usually abate within a few days of the onset of treatment. Patients may be reluctant to report sexual side effects, but they may discontinue treatment because of them. Concerned patients should be advised to watch their diets carefully while taking the medication. Patients should be cautioned not to discontinue their medications without consulting the physician, and only then by gradually decreasing the dose. As with most medications, antidepressants were not initially tested in older women, but several are under consideration by the U. The studies upon which the decision was based included no subject who had committed suicide. Suicidal thoughts, which are extremely common, were conflated with serious attempts, all lumped to gether as suicidality. Atypical Agents Medications considered atypical include venlafaxine, lithium salts, and anticonvulsants, which are effective mood stabilizers used for bipolar disorders (126130).
