The hippocampus is smaller in several stressrelated neuropsychiatric disorders medicine youth lyrics buy zofran 4mg otc, including recurrent depression. Postmortem studies show reduced concentrations in suicide compared with non-suicide deaths. Adult humans with untreated depressive illness have three times lower concentrations when compared with Mood (affective) disorders both healthy controls or those that have received antidepressant treatment. BDNF therefore has potential as an objective marker of depression and its response to treatment as well as being a potential target for treatment of the disorder itself. Sleep A reduced time between onset of sleep and REM sleep (shortened REM latency) and reduced slow wave sleep both occur in depressive illness. Families with several sufferers of depressive illness can share these traits, suggesting that sleep patterns may be inherited and predispose to depression. Stop depressing drugs (alcohol, steroids) Regular exercise (good for mild to moderate depression) Antidepressants (choice determined by side-effects, co-morbid illnesses and interactions) Adjunctive drugs. Psychological Social Childhoodtraumasandpersonality Physical, sexual and emotional abuse or neglect in childhood all predispose adults to depressive illness, but the effect is non-specific. Treatmentscombined Socialfactors Some 30% of women will develop a depressive illness after a severe life event or difficulty, such as a divorce, and this is compounded by low self-esteem and a lack of a confiding relationship. Note that this occurs acutely and that although an equally rapid depletion of monoamines has an acute mood lowering effect, the mood elevating benefits of these drugs require weeks of continuous administration. The effects of chronic administration of monoamine reuptake inhibitors are various. Examples include an increase in the synthesis of binding proteins necessary for serotonin receptor activity and increases in cyclic AMP activation which in turn increases BDNF synthesis, enhances glucocorticoid receptor sensitivity and inhibits cytokine signalling. These may be secondary to the acute restoration of monoamine levels but rely upon transcriptional and translational changes that alter neuronal plasticity. It is this protein synthesisdependent process that is currently thought to be the final pathway responsible for the clinical effect of the drugs. As the neurobiology for depressive illness becomes clearer, so too are novel approaches to its treatment; some of the novel targets under active investigation are listed in Box 23. Stress in turn triggers various brain changes in both stress hormones (such as the release of corticotrophinreleasing hormone) and neurotransmitters. We can thus start to glimpse the model of an integrated biopsychosocial model of depressive illness. This model challenges dualistic ideas that depressive illnesses are either psychological or physical; depressive illnesses involve both the mind and the body, which are themselves indivisible. Treatmentofdepressiveillness the patient needs to know the diagnosis to provide understanding and rationalization of the overwhelming distress inherent in depressive illness. The further treatment of depressive disorders involves physical, psychological and social interventions (Box 23. Patients who are actively suicidal, severely depressed (with or without psychotic symptoms) should be admitted to hospital. Admission is necessary for perhaps 1 in 1000 people with clinical depression in primary care. This provides the patient a break from self-care, and allows support, listening, observation, the close monitoring of treatments and the prevention of suicide. This is particularly likely to happen if the patient is elderly, severely or even terminally ill. Exercise There is good evidence that regular exercise, particularly involving other people, can help relieve depressive illness of 1171 23 Psychological medicine General approach to drug treatment of depression Recreational drugs such as alcohol should be stopped. Prescribed medicines suspected of exacerbating depression, such as corticosteroids, should be gradually stopped or reduced to a safe minimum. Treatment with antidepressants is more successful when accompanied by sufficient patient education and regular follow-up, particularly a week after starting treatment and throughout the following 6 weeks. The commonest two pharmacological types of antidepressants are selective serotonin reuptake inhibitors (SSRIs) and tricyclic antidepressants (TCAs). Choice depends on their side-effects, which can be used to positive effect (sedating drugs given at night to enhance sleep), and their safety. A course of antidepressants should be given until 6 months after recovery from a first episode to prevent relapse. Stopping antidepressants immediately upon recovery leads to a 50% relapse rate within 6 months. The two greatest problems with these drugs are persuading the patient to take them and adherence, since 80% of the UK public wrongly believe that they are addictive. Adolescents, in particular, may develop suicidal thoughts with SSRIs; only fluoxetine is licensed in the UK for adolescents for this reason. Further studies suggest that this is a small risk, if present, and no study has shown a significant increased risk of suicide itself. One in five patients also has sexual sideeffects, such as erectile dysfunction and loss of libido. Ariskofbleeding is associated with SSRIs and is thought to be due to the inhibition of serotonin uptake by platelets as part of normal aggregation in response to vascular injury. To date, much of the reported incidence relates to gastrointestinal bleeding and any patient with one or more risk factors for upper gastrointestinal bleeding, such as taking a nonsteroidal anti-inflammatory, should be given gastro-protection with a proton pump inhibitor.
Further information is obtained from diurnal/postural changes in plasma aldosterone levels (which tend to rise with adenomas between 09:00 hours supine and 13:00 hours erect samples; in contrast symptoms 8 weeks generic zofran 4 mg, they fall with hyperplasia) medicine klonopin purchase zofran 4mg with mastercard, measurement of 18-OH cortisol levels (raised in adenoma) and venous catheterization for aldosterone levels symptoms anemia generic zofran 4 mg amex.

Most tumours release both noradrenaline (norepinephrine) and adrenaline (epinephrine) but large tumours and extra-adrenal tumours produce almost entirely noradrenaline. Paragangliomas typically occur in the head and neck but are also found in the thorax, pelvis and bladder. They are more closely associated with other genetic associations than is phaeochromocytoma. The association of paraganglioma, bilateral adrenal phaeochromocytomas, positive family history or young age at presentation is seen in multiple endocrine neoplasms (p. Mutations in the succinate dehydrogenase (SDHD) gene have been shown to be strongly associated with the development of paraganglioma. Genetic testing for MEN2, VHL and SDHD mutations should be performed in all people with confirmed phaeochromocytoma or paraganglioma. Treatment Tumours should be removed if this is possible; 5-year survival is about 95% for non-malignant tumours. The alpha-blockade must precede the beta-blockade, as worsened hypertension may otherwise result. Surgery in the unprepared patient is fraught with dangers of both hypertension and hypotension; expert anaesthesia and an experienced surgeon are both vital, and sodium nitroprusside and phentolamine (a rapid acting alpha blocker) should be available in case sudden severe hypertension develops. When operation is not possible, combined alpha- and beta-blockade can be used long term. Radionucleotide treatment with MIBG has been used but with limited success in malignant phaeochromocytoma. Patients should be kept under clinical and biochemical review after tumour resection as over 10% recur or develop a further tumour. Some 25% are multiple and 10% malignant, the latter being more frequent in the extra-adrenal tumours. Clinicalfeatures the clinical features are those of catecholamine excess and are frequently, but not necessarily, intermittent (Table 19. All people with suspected phaeochromocytomas must be investigated because phaeochromocytomas may cause acute cardiovascular compromise during routine medical procedures, and can also present with sudden death if the diagnosis is missed. Clonidine suppression test may be appropriate, but should only be performed in specialist centres. CT scans, initially of the abdomen, are helpful to localize the tumours, which are often large. At normal concentrations the kidney is the predominant site of action of vasopressin. Vasopressin stimulation of the V2 receptors allows the collecting ducts to become permeable to water via the migration of aquaporin-2 water channels, thus permitting reabsorption of hypotonic luminal fluid (p. At high concentrations vasopressin also causes vasoconstriction via the V1 receptors in vascular tissue. Changes in plasma osmolality are sensed by osmoreceptors in the anterior hypothalamus. Vasopressin secretion is suppressed at levels below 280 mOsm/kg, thus allowing maximal water diuresis. Above this level, plasma vasopressin increases in direct proportion to plasma osmolality. At the upper limit of normal (295 mOsm/kg) maximum antidiuresis is achieved and thirst is experienced at about 298 mOsm/kg. Biochemistry Diabetes insipidus (DI) Clinicalfeatures Deficiency of vasopressin (ADH) or insensitivity to its action leads to polyuria, nocturia and compensatory polydipsia. The most common is hypothalamic-pituitary surgery, following which transient DI is common, frequently remitting after a few days or weeks. Familial isolated vasopressin deficiency causes DI from early childhood and is dominantly inherited, caused by a mutation in the AVP-NPII gene. High or high-normal plasma osmolality with low urine osmolality (in primary polydipsia plasma osmolality tends to be low).

Asthma in every fifth child in Oslo, Norway: a 10-year follow up of a birth cohort study. Lifetime prevalences and association with sex, age, smoking habits, occupational airborne exposures and respiratory symptoms. At least 4 different specialties deal with allergic patients (pediatrics, otolaryngology, pulmonology, dermatology, gastroenterology, and others). There are known to be some specialists working in Norway who have obtained certification in allergology from other countries. General practitioners are not specially trained in allergic diseases beyond their education in general medicine where allergic diseases are treated together with other diseases, such as asthma being taught together with other obstructive lung diseases. There are few allergy centers, and they are all situated in the larger towns, and urbanized areas. There are great geographical differences in the availability of immunotherapy services, and this is more seldom offered in rural areas. The lack of a formalization of allergology may be the reason for the fragmented education about allergic diseases, for both undergraduate medical students and specialists in Norway. The competence should be linked to service at an allergy center for 1-2 years, and a structured education in allergology.

In 1972, these allergists formed the Philippine Society of Allergology and Immunology, thus formalizing the existence of the distinct subspecialty in the country. Allergy and Immunology is part of the medical curriculum, both in Internal Medicine and Pediatrics in all medical schools. Medical students are taught how to recognize, diagnose and treat allergic/immunologic diseases, nd receive sufficient training to prepare them to become primary health care providers. Most allergy/immunology subspecialists (estimated 80%) practice in the National Capital Region (the region surrounding Manila, the capital of the country). Data Source: Philippine Society of Allergy, Asthma and Immunology membership list We need more physicians trained in allergy. This would be facilitated by arranging for new allergists to spend time studying in centers abroad, and by easier, affordable access for clinicians to information and education about allergy. Epidemiological studies are required to assess prevalence of allergic diseases on a regular basis.

Complications the skin is one of the largest organs of the body, so perhaps it is no surprise that inflammation of the whole organ can cause metabolic and haemodynamic problems. Erythema multiforme Erythema multiforme (EM) is a hypersensitivity rash of acute onset frequently caused by infection or drugs. In 50% of cases, the cause is not found but the following should be considered: Capillary leak syndrome is the most severe complication and has been responsible for a fatal outcome in some cases of psoriasis, although this is extremely rare. It is thought that the inflamed skin releases large quantities of cytokines that cause a generalized vascular leakage. Changes in serum electrolytes and 1216 Herpes simplex virus (the most common identifiable cause) Other viral infections. SLE, polyarteritis nodosa) HIV infection Cutaneous signs of systemic disease Table 24. Biopsy through the ulcer edge shows an intense neutrophilic infiltrate and occasionally a vasculitis but the diagnosis depends mostly on the clinical appearance. The rash tends to be symmetrical and commonly affects the limbs, especially the hands and feet where palms and soles may be involved. Rarely, recurrent erythema multiforme can occur and this is triggered by herpes simplex infection in 80% of cases. Inflammatory bowel disease Rheumatoid arthritis Myeloma, monoclonal gammopathy, leukaemia, lymphoma Liver disease. Some advocate the use of oral steroids in severe mucosal disease but this remains controversial. Recurrent erythema multiforme can be treated with prophylactic oral aciclovir (200 mg twice daily) even if no cause has been found, as 80% of cases appear to be driven by herpes simplex virus. Acanthosis nigricans Acanthosis nigricans presents as thickened, hyperpigmented skin predominantly of the flexures. In older people it normally reflects an underlying malignancy (especially gastrointestinal tumours). Pyoderma gangrenosum Pyoderma gangrenosum is a condition of unknown aetiology that presents with erythematous nodules or pustules which Acanthosis nigricans in an obese individual. Facial erythema and a magenta-coloured rash around the eyes with associated oedema are usually present. The diagnosis is made from the clinical appearance, muscle biopsy, electromyography (EMG) and a serum creatine phosphokinase. There is a childhood form, which usually occurs before the age of 10 and which eventually resolves. This type is associated with calcinosis in the skin, weak muscles and contractures. Some cases are associated with an underlying malignancy whereas some are associated with other autoimmune rheumatic diseases. A linear variant exists in childhood which is more severe as it can cause atrophy of underlying deep tissues and thus cause unequal limb growth or scarring alopecia. Rarely sclerodermatous skin changes may be seen in Lyme disease (acrodermatitis chronica atrophicans), chronic graft-versus-host disease, polyvinyl chloride disease, eosinophilic myalgia syndrome (due to tryptophan therapy) and bleomycin therapy. Lupus erythematosus (LE) There are three clinical variants to this disease but some patients may show features of more than one type. Chronic discoid lupus erythematosus (CDLE) Subacute cutaneous lupus erythematosus (SCLE) Systemic lupus erythematosus (SLE). The aetiology is unknown but variable autoantibodies may be found in all types, suggesting that it is an automimmune disorder. Very rarely it can be induced by certain drugs such as phenothiazines, hydralazine, methyldopa, isoniazid, tetracycline, mesalazine and penicillin. Chronic discoid lupus erythematosus (CDLE) CDLE is the most common type of LE seen by dermatologists and more frequently affects females. Clinically it presents with fixed erythematous, scaly, atrophic plaques with telangiectasia, especially on the face or other sun-exposed sites. Skin biopsy shows a dense patchy, dermal cellular infiltrate (mostly T cells) which often is centred on appendages. Epidermal basal layer damage, follicular plugging and hyperkeratosis may be present. Treatment Skin disease may respond to sunscreens and hydroxychloroquine (200 mg twice daily) as well as immunosuppressants. Systemic sclerosis and morphea both show sclerodermatous changes but are separate conditions. Systemic sclerosis (often called scleroderma) has cutaneous and systemic features and is discussed fully on page 538. Lesions are usually on the trunk and appear as bluish red plaques which progress to induration 1218 Cutaneous signs of systemic disease Treatment First-line therapy is with sunscreens and potent topical steroids. Oral prednisolone is beneficial but its use is limited by its side-effect profile.
