A certain amount of exam anxiety keeps us energized, motivated, alert, and focused. But too much anxiety can interfere with exam performance by blocking our recall or thinking abilities, by fostering negative frames of mind, or even by promoting panic reactions. This type of anxiety may be a product of our underestimating our abilities to perform or of the resources we have available to help us to perform to our desired levels on exams. Conversely, exam anxiety may be a natural reaction to insufficient exam preparation. Exam anxiety can result in: Physical Indicators Perspiration, sweaty palms, feeling too hot or cold Headaches, upset stomach, nausea Rapid heart beat, shallow/irregular breathing, dizziness Muscle tightness Emotional Indicators Feeling guilty, angry, depressed or unsure Behavioural Indicators Procrastination and avoidance Excessive study Over/Under eating; Poor nutrition Sleeping too much or too little Fatigue or inability to relax Alcohol or drug misuse Cognitive Indicators Negative or defeating self-talk Excessive worry Difficulty with concentration or focus Difficulty retrieving or selecting key terms or concepts Difficulty organizing, integrating or expressing your thoughts Going blank on exam questions Remembering the correct answers after the exam is over 2 Some things that can increase exam anxiety are: Insufficient Exam Preparation Cramming the night before the exam Inadequate time management Inadequate study skills or study habits Worrying About Past exam performance Poor present performance Negative consequences of poor performance How others are doing on the exam compared to you Exam anxiety indicators themselves Stimulant Use Caffeine Nicotine Amphetamines Cocaine If the anxiety is severe, persistent, or generalized beyond exam situations, you may benefit from seeing a physician or counsellor. Medical conditions like hyperthyroidism, hypothyroidism, vitamin B12 deficiency, or hypoglycaemia can increase anxiety levels if left untreated. As well, counsellors can work with you to reduce the levels of anxiety or stress that you experience. There are a number of things you can do to help reduce exam anxiety and turn those uncomfortable and unhelpful thoughts, feelings, and behaviours around. Pressing fingernails into palm) Have a drink of water or a snack Wear, touch or look at something with positive associations; this can trigger a calming response (ie. Concentrate on Your Breathing Anxiety can lead to shallow, fast, or irregular breathing. Likewise, shallow, quick, or irregular breathing can increase physical sensations of anxiety. Those breathing patterns can create an imbalance of oxygen and carbon dioxide in the body and brain, heightening physical indicators often associated with anxiety and, in turn, increasing our cognitive interpretations that what we are experiencing is due to anxiety. Although most people carry muscle tension in different areas of their bodies, most people report increased levels of relaxation and decreased levels of physical tension and anxiety on completing the progressive muscle relaxation exercise. Imagery involves actively visualizing scenes that are tranquil and relaxing for you. After a few deep breaths: Step 1 Touch your thumb to your first finger and think back to a time when your body felt a deep healthy fatigue (ie. After a long hike/bike ride) Remember the feeling of your muscles relaxing and your heart beating slowly Step 2 Touch your thumb to your second finger and think back to a time when you had a big achievement in your life or when you had finished an important project Feel the pride of accomplishing something important to you Step 3 Touch your thumb to your third finger and think back to the nicest compliment you have ever received. Practicing this exercise everyday for a few weeks will set up an automatic relaxation process that you can activate whenever you begin to notice the stress or anxiety starting. Simply touch each finger to your thumb, or all four at the same time, and feel yourself relax. Fill in the following chart: When you are working during the exam the way you would like to .

Pathogenesis: Microconidia or hyphal fragments are inhaled and travel to the alveoli where they are phagocytosed by macrophages and convert to yeast forms symptoms 0f low sodium purchase discount norpace on-line. Lymphatics spread the organism to the mediastinal lymph nodes and to the systemic circulation where the rmononuclear phagocyte system is infected treatment norovirus cheap norpace 150 mg on-line. It may be seen on peripheral blood smear or impression smears of an oropharyngeal lesion symptoms ulcerative colitis order discount norpace online. Blastomycosis Organism: Blastomyces dermatitidis Epidemiology: Blastomycosis is found in North America treatment centers for alcoholism order norpace 100mg, primarily in the Ohio, Missouri and Mississippi river valleys, and especially in Kentucky, Missouri, Wisconsin, Iowa, Arkansas, Louisiana, Tennessee, Illinois and Wisconsin. Its ecology has not been well defined, but it is thought to be associated with soil, wood and/or areas near water. Diagnosis: Fungal culture and microscopic fungal examination of lower respiratory tract, bone, skin and/or mucous membranes is recommended. Coccidioidomycosis (Valley Fever) Organisms: Coccidioides immitis (found in California); Coccidioides posadasii Epidemiology: this organism is found in the Southwestern region of North America. The soil is alkaline and has a high salt content supporting growth of short stubby vegetation such as the creosote bush, mesquite trees, cacti and yucca plants. Burrowing rodents found in these areas have been associated with distribution of the organism. These organisms disappear from the soil during the wet months but reappears during the Geographic distribution of coccidioidomycosis dry summer and fall months. History: Infected patients may have a history of exposure to archaeological digs, dust storms, or construction or agricultural activities. Sometimes only a walk around a golf course or another area is enough to acquire an infection. The often barrel-shaped arthroconidia alternate with empty disjunctor cells that fracture easily, releasing the arthroconidia. In the body, arthroconidia transform into rounded spherules that are antiphagocytic. The spherule form contains endospores that resemble yeasts but do not exhibit budding. Importantly, these organisms are extremely infectious in the mold form, and therefore hazardous to work with in the laboratory. Mayo Clinic College of Medicine Medical Microbiology 180 Paracoccidioidomycosis (South American Blastomycosis) Organism: Paracoccidioides brasiliensis Epidemiology: this infection is usually found in South America. Penicilliosis septa Organism: Penicillium marneffei Epidemiology: this infection is usually found in immunocompromised persons (eg. Opportunistic Fungal Infections Opportunistic infections are caused by saprophytic. Under normal circumstances the immune system prevents overgrowth of these organisms. An immunocompromised host may be susceptible to infections by opportunistic fungi. Factors that can contribute to the development of invasive opportunistic fungal infection include immunosuppression. There is a wide range of fungal organisms capable of causing opportunistic infections. The opportunistic infections we will focus on include zygomycosis, aspergillosis, candidiasis, cryptococcosis, and others. Mayo Clinic College of Medicine Medical Microbiology 181 Mucormycosis (Zygomycosis) Organisms: the mucormycetes (zygomycetes) include members of the genus Rhizopus, Mucor, Lichthemia (Absidia) and others. Epidemiology: Mucormycetes are found worldwide and are ubiquitous in nature; they are found in or on fruits, bread, decomposing plants, grain, or soil. History: Activities that provide an opportunity for inhalation of spores or traumatic implantation of an Hyphae of a mucormycete organism into tissue pose a risk for zygomycosis. Pathogenesis: Infection occurs in patients with diabetes or neutropenia, usually beginning in either the sinuses or lungs. Spores are deposited on the palate or nasal mucosa, spread through the sinuses to the orbital space to the brain. Mucormycetes are angioinvasive; vascular invasion and a propensity for spread through tissue planes are characteristic. Diagnosis: Direct fungal examination and/or culture of respiratory tract, central nervous system, nose and sinus, and/or skin and mucous membrane specimens is recommended. In addition to direct exam and fungal culture, in situ hybridization probes can Hyphae of a mucormycete be used for identification of organisms in biopsy tissue. Mayo Clinic College of Medicine Medical Microbiology 182 Aspergillosis Organisms: About 200 species of Aspergillus are known, but only a few are clinically important. Many other species have been reported to cause disease but their frequency is low. History: Patients often have a history of exposure to dusts produced by demolition or construction activities both exterior and interior, potted plants on hospital premises, handling of compost, grain, exposure to air from contaminated duct systems, or other activities associated with aerosolization of conidia of Aspergillus sp. Cell mediated immune deficiency or neutropenia increase the risk of aspergillosis. Pathogenesis: Respiratory tract and disseminated infection occur after inhalation of conidia by the immunocompromised host. Aspergilli may infect the sinuses, external auditory canal, nails, or cornea, or grow in the bronchial tree eliciting a hypersensitivity reaction. On microscopic examination, look for septate, dichotomously branched hyphae, 3-10 fim in diameter. Most species cannot be Aspergillus fungus ball (aspergilloma) in a recognized by the colonial morphology. Common species are easily small cavitary lesion identified based on microscopic examination of colonies. Mayo Clinic College of Medicine Medical Microbiology 183 Candidiasis Organisms: Candida albicans (most common species), Candida tropicalis, Candida glabrata, Candida parapsilosis, Candida lusitaniae, Candida dubliniensis, Candida krusei, and numerous other species of Candida cause candidiasis. Epidemiology: Most species are part of the normal flora of the mouth, skin, vagina, gastrointestinal or respiratory tracts; they are found worldwide. They are also found on plants, in water and dairy products, on fruits and vegetables, etc. History: Infection is associated with interruption of mechanical barriers or indwelling intravascular catheters, gastrointestinal surgical procedures, foreign bodies. Breaches in the mucous membranes of the host are of a common source of candidemia in neutropenic patients. A break occurs in a mucous membrane or tissue, the organism enters the Germ-tube formation by Candida albicans systemic circulation and becomes phagocytosed by neutrophils and monocytes where intracellular myeloperoxidase kills the organism (in patients with normal host defense mechanisms). In neutropenic patients or those with immune defects in which they lack myeloperoxidase, cells remain viable and easily spread into systemic circulation. Candida species are adept biofilm formers, contributing to the pathogenesis of foreign body-related infection. Diagnosis: the presence of budding yeast cells and pseudohyphae (constricted at the ends) and/or hyphae with regular septations are diagnostic. Colonies of Candida are white to buff, pasty, and grow on usual laboratory culture media within 24-96 hours. History: Contact with dust in buildings contaminated with pigeon excreta, demolition of buildings, cleaning of old barns, and spelunking are risk factors. At risk India ink stain of Cryptococcus patients often have compromised cell-mediated immunity. Diagnosis: Cryptococcus capsular antigen can be sensitively and rapidly detected in blood and/or cerebrospinal fluid. Cultured organism is identified by urease production, carbohydrate utilization, and pigment production on niger seed agar. Pneumocystosis Organism: Pneumocystis jiroveci (formerly Pneumcocystis carinii) is different than the other fungi we have been discusing.

The classical triad of cerebral calcifcations symptoms 0f parkinson disease purchase cheapest norpace, chorioretinitis medications heart disease buy norpace 100mg on line, and hydrocephalus is rare but it is highly suggestive of congenital toxoplasmosis symptoms questionnaire discount norpace 150 mg otc, and it is seen primarily in babies whose mothers were not treated for toxoplasmosis during gestation acne natural treatment order norpace 100mg on-line. Toxoplasma gondii infection acquired after birth may be asymptomatic, except in immunocompromised people. When symptoms develop, they are nonspecifc and include malaise, fever, headache, sore throat, arthralgia, and myalgia. Occasionally, patients may have a mononucleosis-like illness associated with a macular rash and hepatosplenomegaly. Myocarditis, myositis, hepatitis, pericarditis, pneumonia, and skin lesions are rare complications in the United States and Europe. However, these manifestations and more aggressive disease, including brain abscesses, life-threatening syndromes, and death, have been observed in immunocompetent people infected in certain tropical countries in South America, such as French Guiana, Brazil, and Colombia. Isolated ocular toxoplasmosis commonly results from reactivation of congenital infection but also occurs in people with acquired infection. Characteristic retinal lesions (chorioretinitis) develop in up to 85% of young adults after untreated congenital infection. Acute ocular involvement manifests as blurred vision, eye pain, decreased visual acuity, foaters, scotoma, photo phobia, or epiphora. The most common late fnding is chorioretinitis, which can result in unilateral vision loss. Ocular disease can become reactivated years after the initial infection in healthy and immunocompromised people. In this latter group of patients, the differential diagnosis should be widened to other pathogens, such as molds and nocardia. Seropositive hematopoietic stem cell and solid organ transplant patients are at risk of their latent T gondii infection being reactivated. In these patients, toxoplasmosis may manifest as pneumonia, unexplained fever, myocarditis, hepatosplenomegaly, lymphadenopathy, or skin lesions in addition to brain abscesses and diffuse encephalitis. T gondii-seropositive solid organ donors (D+) can transmit the parasite via the allograft to seronegative recipients (R-). Thirty percent of D+/Rheart transplant recipients develop toxoplasmosis in the absence of anti-T gondii prophylaxis. The term T gondii infection is reserved for the asymptomatic presence of the parasite in the setting of an acute or chronic infection. In contrast, the term toxoplasmosis should be used when the parasite causes symptoms and/or signs during the acute infection or reactivation of chronic infection in immunosuppressed patients. The tachyzoite and the host immune response are responsible for symptoms observed during the acute infection in humans or during the reactivation of a latent infection in immunocompromised patients. The tissue cyst is responsible for latent infection and usually is present in skeletal muscle, cardiac tissue, brain, and eyes of humans and other vertebrate animals. The oocyst is present in the small intestine of cats and other members of the feline family; it is responsible for transmission through soil, water, or food contaminated with infected cat feces. The seroprevalence of T gondii infection (a refection of the chronic infection and measured by the presence of T gondii-specifc IgG antibodies) varies by geographic locale and the socioeconomic strata of the population. The age-adjusted seroprevalence of the parasite in the United States has been estimated at 11%. Cats generally acquire the infection by feeding on infected animals (eg, mice), uncooked household meats, or water or food contaminated with their own oocysts. Cats may begin to excrete millions of oocysts in their stools 3 to 30 days after primary infection and may shed oocysts for 7 to 14 days. After excretion, oocysts require a maturation phase (sporulation) of 24 to 48 hours in temperate climates before they are infective by the oral route. Sporulated oocysts survive for long periods under most ordinary environmental conditions and can survive in moist soil, for example, for months and even years. Intermediate hosts (including sheep, pigs, and cattle) can have tissue cysts in the brain, myocardium, skeletal muscle, and other organs. Humans usually become infected by consumption of raw or undercooked meat that contains cysts or by accidental ingestion of sporulated oocysts from soil or in contaminated food or water. A large outbreak linked epidemiologically to contamination of a municipal water supply also has been reported. A recent epidemiologic study revealed the following risk factors associated with acute infection in the United States: eating raw ground beef; eating rare lamb; eating locally produced cured, dried, or smoked meat; working with meat; drinking unpasteurized goat milk; and having 3 or more kittens. In this study, eating raw oysters, clams, or mussels also was identifed as novel risk factor. Untreated water also was found to have a trend towards increased risk for acute infection in the United States. Although the risk factors for acute infection have been reported in studies from Europe, South America, and the United States, up to 50% of acutely infected people do not have identifable risk factors or symptoms. Thus, T gondii infection and toxoplasmosis may occur even in patients without a suggestive epidemiologic history or illness. Only appropriate laboratory testing can establish or rule out the diagnosis of T gondii infection or toxoplasmosis. Transmission of T gondii has been documented to result from solid organ (eg, heart, kidney, liver) or hematopoietic stem cell transplantation from a seropositive donor with latent infection to a seronegative recipient. Rarely, infection has occurred as a result of a laboratory accident or from blood or blood product transfusion. In most cases, congenital transmission occurs as a result of primary maternal infection during gestation. Rarely, in utero infection may occur as a result of reactivated parasitemia during pregnancy in chronically infected immunocompromised women. The incidence of congenital toxoplasmosis in the United States has been estimated to be 1 in 1000 to 1 in 10 000 live births. The incubation period of acquired infection, on the basis of a well-studied outbreak, is estimated to be approximately 7 days, with a range of 4 to 21 days. Isolation of the parasite occasionally is attempted for the purpose of genotyping the infecting strain. Immunoglobulin (Ig) G-specifc antibodies achieve a peak concentration 1 to 2 months after infection and remain positive indefnitely. To determine the approximate time of infection in IgG-positive adults, specifc IgM antibody determinations should be performed. The presence of T gondii-specifc IgM antibodies can indicate recent infection, can be detected in chronically infected people, or can result from a false-positive reaction. IgM-specifc antibodies can be detected 2 weeks after infection (IgG-specifc antibodies usually are negative during this period), achieve peak concentrations in 1 month, decrease thereafter, and usually become undetectable within 6 to 9 months. However, in some people, a positive IgM test result may persist for years and without an apparent clinical signifcance. In adults, a positive IgM test should be followed by confrmatory testing at a laboratory with special expertise in Toxoplasma serology when determining the timing of infection is important clinically (eg, in a pregnant woman). The presence of high-avidity IgG antibodies indicates that infection occurred at least 12 to 16 weeks prior. However, the presence of low-avidity antibodies is not a reliable indication of recent infection, and treatment may affect the maturation of IgG avidity and prolong the presence of low-avidity antibodies. Tests to detect IgA and IgE antibodies, which decrease to undetectable concentrations sooner than IgM antibodies do, are useful for diagnosis of congenital infections and infections in pregnant women, for whom more precise information about the duration of infection is needed. T gondii-specifc IgA and IgE antibody tests are available in Toxoplasma reference laboratories but generally not in other laboratories. Diagnosis of Toxoplasma infection during pregnancy should be made on the basis of results of serologic assays performed in a reference laboratory. Essentially any tissue can be stained with T gondii-specifc immunoperoxidase; the presence of extracellular antigens and a surrounding infammatory response are diagnostic of toxoplasmosis. Isolation of the parasite by mouse or tissue culture inoculation also can be attempted from amniotic fuid. Serial fetal ultrasonographic examinations can be performed in cases of suspected congenital infection to detect any increase in size of the lateral ventricles of the central nervous system or other signs of fetal infection, such as brain, hepatic, or splenic calcifcations. Infants who are born to women suspected of having or who have been diagnosed with primary T gondii infection during gestation should be assessed for congenital toxoplasmosis. Women infected shortly before conception (eg, within 3 months of conception) also may be at risk. Detection of Toxoplasma-specifc IgA antibodies is more sensitive than IgM detection in congenitally infected infants. None of the current commercial assays offered in the United States have been cleared by the Food and Drug Administration for in vitro diagnostic use for infants.

Risks and protective factors in childhood anxiety disorders Puberty results in maturational changes not only physically but also emotionally medicine for bronchitis buy norpace cheap online. Puberty may increase risk factors for many psychiatric disorders including anxiety disorders aquapel glass treatment purchase norpace 150 mg with visa. Prevention of Childhood Anxiety Disorders 89 According to Leen-Feldner et al medications resembling percocet 512 buy norpace 100 mg on line, adolescents with advanced pubertal status and greater reactivity to a hyperventilation challenge were at increased risk for panic symptoms (LeenFeldner et al medications during labor 150 mg norpace mastercard, 2007). In a study by Otto et al, 2007), risk factors for fear conditioning were examined in a nonclinical sample. Those in the sample that had higher levels of anxiety sensitivity (increased anxiety symptoms) predicted increased tendency towards fear conditioning (Otto et al,2007). The quality of attachment between an infant and the primary caregiver is an important indicator of future development of anxiety disorders (Erickson et al, 1985; Lewis et al, 1984; Sroufe et al, 1990). In a study by Warren et al,1997, the role of attachment style on the later development of anxiety disorders was studied in 172 children at 12 months and then later at 17. At 12 months a pattern of anxious resistant attachment predicted later anxiety disorders, even after controlling for infant temperament and maternal anxiety. It is estimated that heritability accounts for about 40-50% of anxiety symptoms in children (Thapar et al, 1995). Behavioral inhibition has been identified by Kagan et al(Kagan et al, 1989; Kagan et al, 1991)as a stable temperament style consisting of shyness and elevated physiological arousal having a strong genetic component (DiLalla et al, 1994; Plomin et al, 1989). Children with behavior inhibition are more likely to develop an anxiety disorder (Biederman et al, 1993; Kagan, 1997; Rosenbaum et al, 1993). Other risk factors for childhood anxiety disorders are traumatic and stressful life events following which children have higher levels of fears. Higher rates of anxiety disorders are present in children following major natural disasters (Dollinger et al, 1984). Moreover, parenting behaviors have been identified to interact with other risk factors in the development of childhood anxiety. Parents of anxious children often model, prompt, and reinforce anxious behavior in their children (Barrett et al, 1996). Other parental characteristics that contribute to risk factors for childhood anxiety are being overly controlling, critical and, overprotective (Krohne et al, 1991). Protective factors either promote positive development or protect against risk factors. Lastly, the type of responses children use to cope with stressful experiences influence how much anxiety and distress they experience (Spence et al, 2001). Prevention strategies In the past few years school personnel have become interested in programming to address the social and emotional needs of children due to the resultant deleterious effects of difficulties in these areas on their academic and social functioning. In this regard, there has 90 Anxiety and Related Disorders been a shift to implement evidence-based psychosocial treatments in schools in a preventative fashion (Miller et al, 2010). Recent governmental policy initiatives are requiring the implementation of evidence-based treatments in schools (Robertson, David & Rao, 2003). Having a classroom intervention by teachers and school counselors makes it easier to identify children suffering from anxiety. Teachers have unlimited access to children in their classroom and know their strengths and weaknesses well. It is not only cost-effective for teachers to provide the intervention to students but students can learn from peers and share their experiences with them thus providing support (Miller et al, 2010). Individual cognitive behavioral therapy has been studied for childhood anxiety disorders and is effective for 70% for clinically referred children (In-Albon & Schneider, 2007). The recent challenge for many researchers has been to study the successful implementation of these studies into a community or school setting. These studies have the challenge of following the treatment but being flexible to a real-world setting. The Committee on Prevention of Mental Disorders (Mrazek et al, 1994) describes a continuum of interventions going from prevention at one end and treatment at the other end. The following are three main forms of prevention: universal, targeted or selective, and indicated. A universal preventive approaches are either designed to enhance resilience in all children. These programs are more readily accepted because they are proactive, emphasizing positive coping skills and provided to everyone thus avoiding any possibility of stigmatization though labeling. Under the targeted programs, selective programs are for children who are at increased risk of developing disorders and involves screening. Indicated programs also require screening and are for individuals with minimal symptoms who do not meet diagnostic criteria for any disorder. Treatment programs target children with a diagnosed condition (Lowry-Webster et al, 2001). In this paper both the universal and targeted school-based anxiety prevention programs will be reviewed. Universal prevention strategies A study by Hains (Hains et al, 1992) examined the effectiveness of two cognitive-behavioral interventions to help adolescent boys cope with stress and other negative emotions. The project was described to all sophomores and juniors and those who were interested were invited to attend an orientation meeting. Twenty-five adolescent boys ages 15-16 year old were randomly assigned to either a group receiving cognitive restructuring or to a second group receiving anxiety management training. Both these groups were compared to a wait-list control group on measures of anxiety, anger, self-esteem, depression, and reports of anxious self-statements. Both the intervention groups showed significant decline in levels of anxiety, expression of anger, and depression. There are 2-4 parent sessions teaching parents coping strategies for their own anxiety, reinforcement strategies, contingency management and problem-solving and communications skills. Children with internalizing symptoms were assigned to either an intervention led by a psychologist, a teacher or a control condition with a standard curriculum. At the end, children reported considerable decrease in anxiety symptoms in either intervention by a psychologist or a teacher. Both groups reported significant decrease in anxiety and the decline was significantly greater in the intervention group regardless of their risk status. A follow up study after one year by Lowry-Webster et al (2003) showed that results were maintained with the intervention group having lower scores on anxiety self-report measures. Eightyfive per cent of children in the intervention group who were scoring above the clinical cutoff for anxiety and depression were symptom free in the intervention condition compared to 31. In a study of universal prevention with 733 children enrolled in grade 6 (ages 9-10) and grade 9 (ages 14-16), Lock et al, 2003 studied children from 7 different socioeconomic school settings. Results showed a general decrease in anxiety scores which were significant for students in the intervention group at the end of the program and at 1 year follow up. This study also showed that children in Grade 6 had higher levels of anxiety before intervention but post-intervention had greater reductions in anxiety and depression at 12 month follow up compared to grade 9 children. In addition, there was a delayed effect in improvement of depression symptoms that was apparent only at the 1 year follow up. In addition, girls tended to have higher levels of anxiety than boys and girls in Grade 6 were more responsive to the intervention than Grade 9 girls. Barrett et al (2006) evaluated the above mentioned study by Lock et al for its long term effectiveness at 36 months. The decrease in scores due to the intervention were maintained in grade 6 but not for children in grade 9 emphasizing the fact that intervention in grade 6 might be an optimal time for decreasing risk for anxiety.

Studies of long-term alprazolam treatment for panic disorder Psycho-education for patients with anxiety disorders involves show that the doses patients use at 32 weeks of treatment are teaching patients about the disorder medications contraindicated in pregnancy discount 150 mg norpace fast delivery, discussing treatment similar to doses used at 8 weeks medicine xifaxan generic norpace 150 mg mastercard, indicating that as a group treatment integrity buy cheap norpace, options medications xl purchase norpace 150mg line, modalities of treatment, and coping strategies. Cognitive behaviour therapy is the only type of psychotherapyCognitive behaviour therapy is the only type of psychotherapy shown to be efficacious in the treatment of panic disorder, withshown to be efficacious in the treatment of panic disorder, with or without agoraphobia. A Depending on availability of treatment and patient preference, cognitive behaviour therapy or combination 4. There is also strong evidence to support the efficacy of venlafaxine in patients with generalised anxiety disorder. Due caution must be exercised when prescribing to patients who are at risk of abusing substances. Grade B, Level 2++ C Hydroxyzine may be used as adjunctive treatment together with other anxiolytic agents for treatment of generalised anxiety disorder. Grade B, Level 1+ 39 A Drug treatment for generalised anxiety disorder needs to be continued for at least 32 weeks as high relapse rates were reported after discontinuing medications. While combination therapy (addition of medication to cognitive behaviour therapy) will enhance short term outcomes, there is no evidence to support, at present, that combination therapy will improve long term outcomes. Specific phobia is about twice as common in women, with age of onset ranging from 5 to 12 years (mean 7 years). Components of cognitive behaviour therapy for specific phobia may include systematic desensitisation, imaginal exposure and in-vivo exposure. Grade A, Level 1++ As much as 70-85% of specific phobias could be effectively treated by exposure therapy. One longterm follow-up study suggested that relapse was common after successful treatment with combination imipramine and psychotherapy. Different surveys suggest differing prevalence rates for social anxiety disorder, ranging from 3%130 to 12. A Benzodiazepines may be used on a short-term basis for temporary anxiety relief pending resolution of phobic symptoms with other forms of treatment. Grade A, Level 1+ Exposure to feared situations is a crucial component of cognitive behaviour therapy. Group cognitive behaviour therapy approaches are also useful and often include elements of social skills training. Cognitive behaviour therapy interventions include in-vivo exposure, cognitive restructuring, relaxation training and selfcontrol desensitisation, of which exposure-based interventions are the most efficacious for social anxiety disorder. A study that followed up patients for 40 years found that 20% had complete recovery, although most showed some improvement in terms of clinical symptoms and functioning. If the patient does not respond to treatment in adequate dosages, the medication may be changed or specialist opinion sought. Open label studies171-173 and two small double blind studies174, 175 suggest that venlafaxine may be effective in the treatment of obsessive-compulsive disorder. A double-blind crossover study176 suggested that venlafaxine may actually be less effective than paroxetine in the treatment of refractory patients. Monitor blood pressure during treatment as venlafaxine at high doses can raise blood pressure. Grade A, Level 1+ There is preliminary evidence suggesting that duloxetine177 and mirtazapine178 could be efficacious in the treatment of obsessivecompulsive disorder. However, more research needs to be done before these can be considered as monotherapy for uncomplicated obsessive-compulsive disorder. Hence it is important to continue antidepressants after clinical improvement has occurred. Risk factors include severe or prolonged trauma, trauma/abuse during childhood, pre-existing history of psychiatric illness, comorbid substance abuse, poor social support and female gender. In a relapse prevention study, fluoxetine was also found to be superior to placebo. Responders to the initial study sustained their initial response, and patients who failed in the initial study eventually became responders. A Either amitriptyline or imipramine may be considered for post-traumatic stress disorder if the first-line and second-line treatments are ineffective or poorly tolerated. A Benzodiazepines should not be used for the treatment of post-traumatic stress disorder. Long-term efficacy was demonstrated for fluoxetine, sertraline213-216 and venlafaxine. These findings support consensus recommendations that duration of treatment should last from 6-12 months for acute post-traumatic stress disorder,203 and for at least 12 months in the case of chronic post-traumatic stress disorder to prevent relapse. Eye movement desensitisation and reprocessing therapy has been found to be effective in the treatment of post-traumatic stress disorder,240-245 but a meta-analysis showed that it had a smaller effect size compared to cognitive behaviour therapy. All psychotropic medications cross the placenta, and are present in amniotic fluid, and breast milk. To minimise the risk of harm to the foetus or child, drugs should be prescribed cautiously for women who are planning a pregnancy, who are already pregnant, or who are breastfeeding. Grade D, Level 4 55 D When prescribing a drug for a woman with an anxiety disorder who is planning to become pregnant, already pregnant, or is breastfeeding:249 choose drugs with the lowest risk potential for the mother and the foetus/infant start at the lowest effective dose, and slowly titrate upwards continue for the shortest possible duration250 use monotherapy instead of combination treatment250 Grade D, Level 4 9. The risk of cardiovascular and other congenital malformations may be higher with paroxetine than other antidepressants. There was, however, a small but significantly increased risk for oral cleft according to data from the available case-control studies. Currently available evidence suggests that benzodiazepine exposure during pregnancy is not associated with an increasing risk of congenital major malformation but is associated with a high rate of spontaneous abortion. Iqbal et al (2002) suggested that diazepam and chlordiazepoxide should be preferred if a benzodiazepine needs to be prescribed in 58 58 9. Caution should be exercised in prescribing clonazepam and lorazepam in the first trimester, owing to reports of higher risk of major malformations after in-utero exposure. There was, however, a small risperidone and quetiapine,270,272 cases of gestational diabetes but significantly increased risk for oral cleft according to data have been reported with the use of atypical antipsychotics. Currently available evidence suggests that in patients suffering from or at risk of gestational diabetes. Serum levels are not indicated on a regular basis except in the case of clinical indication or concern. Controlled studies on the use of antidepressants during lactation are still lacking. Most antidepressants are excreted in breast milk, although the effects on the infant are not well understood. Antidepressants generally have long or intermediate half-life, and are usually suspected to accumulate in the nursing infant. However the advantages of breastfeeding are likely to outweigh the minimal risk of side-effects of maternal drug use to the infant. Fluoxetine and venlafaxine are present in breast milk at relatively high levels and produce the highest infant plasma concentrations. Citalopram levels have been measurable in some infants, even though mostly relatively low. Grade D, Level 3 D Drugs for which little data exist, such as fluvoxamine, venlafaxine, bupropion and mirtazapine, should not be considered as first-line therapies in breastfeeding women, but they may be used in special cases. Gradual tapering and stopping of benzodiazepines may be attempted at a later stage when the infant has grown bigger. This study also found that more than $23 billion of these costs were associated with repeated use of health care services as patients with anxiety disorders sought relief of symptoms that mimic physical illnesses. There is also a gap in the treatment of anxiety disorders in Singapore, as shown by the Singapore National Mental Health Survey. Issakidis285 found that adopting an evidence-based approach to the treatment of anxiety disorders would result in greater population health gain at similar cost to that of current care, resulting in substantial gains in the cost-effectiveness of treatment. When the impact of mental health interventions in a primary care setting were estimated,286 the single most cost-effective strategy for panic disorder is the scaled-up use of older antidepressants (due to their lower cost but similar efficacy compared with newer antidepressants).
