Epilepsy in Bipolar Disorder: Impact on Clinical Features, Course and Outcome

Background and Aims: It is well recognized that mood disorders and epilepsy commonly co-occur. However, the relationship between epilepsy and the clinical features and course of illness in bipolar disorder (BD) is currently unknown. Here we explore the rate of epilepsy within a large sample of individuals with BD and examine bipolar illness characteristics according to the presence or absence of epilepsy. Methods: 1596 participants recruited to the Bipolar Disorder Research Network; a well-defined sample of UK subjects with a diagnosis of BD, completed a self-report questionnaire to assess lifetime history of epilepsy (Ottman et al., 2010). A subset of participants (n = 29) completed a telephone interview assessment to determine expert-confirmed epilepsy status. Lifetime clinical characteristics of illness were compared between BD subjects with and without a history of epilepsy. Results: 127 individuals (8%) screened positively for lifetime history of epilepsy. Bipolar subjects with epilepsy experienced higher rates of: suicide attempt (64.2% vs. 47.4%, p = 0.000367); panic disorder (29.6% vs. 16.1%, p = 0.001); phobias (13.6% vs. 5.7%, 0.004); alcohol abuse (18.6% vs. 10.6%, p = 0.017); and other substance abuse (10.2% vs. 4%, p = 0.009). History of suicide attempt (OR = 1.79, p = 0.013) remained significant within a multivariate model. Similar trends were observed within bipolar subjects with well-defined, expert-confirmed epilepsy (n = 29). Conclusions: Results demonstrate an increased rate of self-reported epilepsy in the BD sample, compared to the general population, and suggest differences in the clinical course of BD according to the presence of epilepsy. Comorbid epilepsy within BD may provide an attractive opportunity for subcategorising for future genetic studies, potentially identifying common underlying mechanisms.

Development of mental health first aid guidelines for panic attacks: a Delphi study

BACKGROUND: Panic attacks are common, and while they are not life-threatening events, they can lead to the development of panic disorder and agoraphobia. Appropriate help at the time that a panic attack occurs may decrease the fear associated with the attack and reduce the risk of developing an anxiety disorder. However, few people have the knowledge and skills required to assist. Simple first aid guidelines may help members of the public to offer help to people who experience panic attacks.

METHODS: The Delphi method was used to reach consensus in a panel of experts. Experts included 50 professionals and 6 people who had experience of panic attacks and were active in mental health advocacy. Statements about how to assist someone who is having a panic attack were sourced through a systematic search of both professional and lay literature. These statements were rated for importance as first aid guidelines by the expert and consumer panels and guidelines were written using the items most consistently endorsed.

RESULTS: Of 144 statements presented to the panels, 27 were accepted. These statements were used to develop the guidelines appended to this paper.

CONCLUSION: There are a number of actions which are considered to be useful for members of the public to do if they encounter someone who is having a panic attack. These guidelines will be useful in revision of curricula of mental health first aid programs. They can also be used by members of the public who want immediate information about how to assist someone who is experiencing panic attacks.

Diagnosing postpartum depression in mothers and fathers : Whatever happened to anxiety?

Although anxiety disorders are documented in the literature for new mothers (but less so for fathers), rates of postpartum caseness tend to include only those with depression when diagnostic interviews or self-report measures validated on such interviews are used. This methodology therefore underestimates the true percentage of women and men who experience significant psychological difficulties postpartum. This has implications for assessment, treatment and screening for postnatal mood disorders. Two studies were conducted on a total of 408 women and 356 men expecting their first child. They were recruited antenatally, and interviewed at 6 weeks postpartum using the Diagnostic Interview Schedule. DSM-IV criteria were applied to determine the presence since birth of depression (major or minor), panic disorder, acute adjustment disorder with anxiety (meeting the criteria for generalised anxiety disorder except for the duration criterion), and phobia. The inclusion of diagnostic assessment for panic disorder and acute adjustment disorder with anxiety increased the rates of caseness by between 57 and 100% for mothers, and 31-130% for fathers, over the rates for major or minor depression. Inclusion of assessment for phobia further increased the rates of disorder in both samples.

Kava and St. John's wort : current evidence for use in mood and anxiety disorders

Background: Mood and anxiety disorders pose significant health burdens on the community. Kava and St John’s wort (SJW) are the most commonly used herbal medicines in the treatment of anxiety and depressive disorders, respectively. Objectives: To conduct a comprehensive review of kava and SJW, to review any evidence of efficacy, mode of action, pharmacokinetics, safety and use in Major Depressive Disorder (MDD), Bipolar Disorder (BP), Seasonal Affective Disorder (SAD), Generalized Anxiety Disorder (GAD), Social Phobia (SP), Panic Disorder (PD), Obsessive-Compulsive Disorder (OCD), and Post Traumatic Stress Disorder (PTSD). Methods: A systematic review was conducted using the electronic databases MEDLINE, CINAHL, and The Cochrane Library during late 2008. The search criteria involved mood and anxiety disorder search terms in combination with kava, Piper methysticum, kavalactones, St John’s wort, Hypericum perforatum, hypericin and hyperforin. Additional search criteria for safety, pharmacodynamics , and pharmacokinetics was employed. A subsequent forward search was conducted of the papers using Web of Science cited reference search. Results: Current evidence supports the use of SJW in treating mild-moderate depression, and for kava in treatment of generalized anxiety. In respect to the other disorders, only weak preliminary evidence exists for use of SJW in SAD. Currently there is no published human trial on use of kava in affective disorders, or in OCD, PTSD, PD or SP. These disorders constitute potential applications that warrant exploration. Conclusions: Current evidence for herbal medicines in the treatment of depression and anxiety only supports the use of Hypericum perforatum for depression, and Piper methysticum for generalized anxiety.

A salutogenic approach to healing following child sexual assault

Decades of research has now produced a rich description of the destruction child sexual assault (CSA) can cause in an individual’s life. Post-Traumatic Stress Disorder (PTSD), Dissociative Identity Disorder, Borderline Personality Disorder, depression, anxiety, Panic Disorder, intimacy issues, substance abuse, self-harm, and suicidal ideation and attempts, are some of the negative outcomes that have been attributed to this type of traumatic experience. Psychology's tendency to dwell within a pathological paradigm, along with popular media who espouse a similar rhetoric, would lead to the belief that once exposed to CSA, an individual is forever at the mercy of dealing with a massive array of accompanying negative effects. While the possibility of these outcomes in those who have experienced CSA is not at all denied, it is also timely to consider an alternative paradigm that up until now has received a paucity of attention in the sexual assault literature. That is to say, not only do people have the ability to work through the painful and personal impacts of CSA, but for some people the process of recovery may provide a catalyst for positive life changes that have been termed post-traumatic growth (Tedeschi & Calhoun, 1995). To begin with in this chapter, the negative sequale’ of childhood sexual assault it discussed initially. Inherent to this discussion are questions of measurement and definitions of sexual assault. The chapter highlights ways in which the term CSA has been defined and hence operationalised in research, and the myriad problems, confusions, and inconclusive findings that have plagued the sexual assault literature. Following this is a review of the sparse literature that has conceptualised CSA from a more salutogenic (Antonovsky, 1979) theoretical orientation. It is argued that a salutogenic approach to intervention and to research in this area, provides a more useful way of promoting healing and the gaining of wisdom, but importantly does not negate the very real distress that may accompany growth. This chapter will then present a case study to elucidate the theoretical and empirical literature discussed using the words of a survivor. Finally, the chapter concludes with implications for therapeutic practice, which includes some practical ways in which to promote adaptation to life within the context of having survived this insidious crime.

Nonlinear measures of QT interval series: novel indices of cardiac repolarization lability: MEDqthr and LLEqthr

In this study, we investigated nonlinear measures of chaos of QT interval time series in 28 normal control subjects, 36 patients with panic disorder and 18 patients with major depression in supine and standing postures. We obtained the minimum embedding dimension (MED) and the largest Lyapunov exponent (LLE) of instantaneous heart rate (HR) and QT interval series. MED quantifies the system's complexity and LLE predictability. There was a significantly lower MED and a significantly increased LLE of QT interval time series in patients. Most importantly, nonlinear indices of QT/HR time series, MEDqthr (MED of QT/HR) and LLEqthr (LLE of QT/HR), were highly significantly different between controls and both patient groups in either posture. Results remained the same even after adjusting for age. The increased LLE of QT interval time, series in patients with anxiety and depression is in line with our previous findings of higher QTvi (QT variability index, a log ratio of QT variability corrected for mean QT squared divided by heart rate variability corrected for mean heart rate squared) in these patients, using linear techniques. Increased LLEqthr (LLE of QT/HR) may be a more sensitive tool to study cardiac repolarization and a valuable addition to the time domain measures such as QTvi. This is especially important in light of the finding that LLEqthr correlated poorly and nonsignificantly with QTvi. These findings suggest an increase in relative cardiac sympathetic activity and a decrease in certain aspects of cardiac vagal function in patients with anxiety as well as depression. The lack of correlation between QTvi and LLEqthr suggests that this nonlinear index is a valuable addition to the linear measures. These findings may also help to explain the higher incidence of cardiovascular mortality in patients with anxiety and depressive disorders. (C) 2002 Elsevier Science Ireland Ltd.

Narrativas médicas do medo: do coração ao cérebro

Desde a síndrome do coração irritável, passando pelas diversas síndromes do fin de siècle e chegando ao triunfo das teorias neurocientíficas sobre a hipersensibilidade dos centros cerebrais de resposta ao alarme e sufocação, a Medicina buscou teorias para explicar a experiência de pavor. Investiga-se o modo como ocorreram, ao longo da história, as transformações da atenção médica sobre o medo e os estados mórbidos que o acompanham. Ao se buscar na literatura médica vestígios de análises científicas sobre o mal-estar intenso, do meio do século XIX ao fim do XX, não se pretendeu construir uma história triunfalista, de modo que as teorias atuais pudessem ganhar status de superioridade em relação às do passado. Evidenciou-se, sim, a importância cultural e a força histórica de cada uma delas, salientando as possíveis continuidades e rupturas de sentido que elas assumiram.

Transtorno de pânico um estudo sobre as matrizes sociais de seu surgimento: a sociedade do risco e a construção contemporânea de bioidentidades

O transtorno de pânico é uma das questões preocupantes em termos de saúde coletiva. Pensamos que tal transtorno se configura como uma nova forma de adoecimento psíquico, categoria que tem penetrado em diferentes espaços sociais, e suas descrições vêm sendo incorporadas ao arcabouço identitário dos sujeitos. Problematizar as matrizes culturais da emergência e difusão deste transtorno, no campo da construção de subjetividade e de identidade, é o objetivo deste estudo. Na pós-modernidade, por um lado, nos centramos nas características do que se denomina sociedade de risco, (BECK, 1998) a qual gera sentimentos de imprevisibilidade, desenraizamento e desfiliação; por outro, juntamente com o desprestígio do ideal da interioridade, observa-se um recurso a se recorrer ao registro do corpo e da biologia como âncora subjetiva. (COSTA, 2005). Com a predominância de um cenário de incerteza e de risco permanente, cria-se uma atmosfera em que a previsibilidade e a confiabilidade são constantemente ameaçadas, Ou seja, o valor da confiança no registro da ontologia refere-se à existência de um ambiente suficientemente confiável e previsível para que os sujeitos experienciem uma constância dos ambientes de ação social e material circundante (WINNICOTT, 1963). Verificaremos, em meio a um cenário de risco ambiente, como o pânico emerge e é difundido com base em matrizes desviantes. O transtorno de pânico, pretensamente radicado no cérebro e determinado pela genética, parece ser uma das entidades às quais as pessoas aderem e ao redor das quais se agregam. Nesse sentido, defendendo que os tipos de patologia, nos quais se inclui o transtorno de pânico, podem servir também como redes de pertencimento, formas de sociabilidade que se organizam em torno de predicados físicos, tanto na esfera da normalidade quanto da patologia, entre as quais o corpo anatomofisiológico se destaca como fenômeno identitário, denominado por alguns autores de bioidentidade (ORTEGA, 2000). Humanizar o conceito transtorno de pânico, portanto, é afirmar que tais sintomas já conheceram outras utilizações. Entendendo o sujeito como um conjunto de crenças podem ser alteradas, revistas, repensadas, redimensionadas (COSTA, 1994). Ao sair da esfera da universalidade e essencialidade, típicas de classificações reducionistas no campo da psiquiatria, para a perspectiva de que existem jogos de linguagem diferentes para se referir ao pânico, percebemos que em vez de o transtorno de pânico existem os pânicos, ou seja, são plurais e diversificadas as diferentes gramáticas para se falar daquilo a que se reduz hoje essa classificação psiquiátrica.

How common are common mental disorders? Evidence that lifetime prevalence rates are doubled by prospective versus retrospective ascertainment.

BACKGROUND: Most information about the lifetime prevalence of mental disorders comes from retrospective surveys, but how much these surveys have undercounted due to recall failure is unknown. We compared results from a prospective study with those from retrospective studies. METHOD: The representative 1972-1973 Dunedin New Zealand birth cohort (n=1037) was followed to age 32 years with 96% retention, and compared to the national New Zealand Mental Health Survey (NZMHS) and two US National Comorbidity Surveys (NCS and NCS-R). Measures were research diagnoses of anxiety, depression, alcohol dependence and cannabis dependence from ages 18 to 32 years. RESULTS: The prevalence of lifetime disorder to age 32 was approximately doubled in prospective as compared to retrospective data for all four disorder types. Moreover, across disorders, prospective measurement yielded a mean past-year-to-lifetime ratio of 38% whereas retrospective measurement yielded higher mean past-year-to-lifetime ratios of 57% (NZMHS, NCS-R) and 65% (NCS). CONCLUSIONS: Prospective longitudinal studies complement retrospective surveys by providing unique information about lifetime prevalence. The experience of at least one episode of DSM-defined disorder during a lifetime may be far more common in the population than previously thought. Research should ask what this means for etiological theory, construct validity of the DSM approach, public perception of stigma, estimates of the burden of disease and public health policy.

Psychiatric correlates of snuff and chewing tobacco use.

Compared to the association between cigarette smoking and psychiatric disorders, relatively little is known about the relationship between smokeless tobacco use and psychiatric disorders. To identify the psychiatric correlates of smokeless tobacco use, the analysis used a national representative sample from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) wave 1. Smokeless tobacco use was classified as exclusive snuff use, exclusive chewing tobacco, and dual use of both snuff and chewing tobacco at some time in the smokeless tobacco user's life. Lifetime psychiatric disorders were obtained via structured diagnostic interviews. The results show that the prevalence of lifetime exclusive snuff use, exclusive chewing tobacco, and dual use of both snuff and chewing tobacco was 2.16%, 2.52%, and 2.79%, respectively. After controlling for sociodemographic variables and cigarette smoking, the odds of exclusive chewing tobacco in persons with panic disorder and specific phobia were 1.53 and 1.41 times the odds in persons without those disorders, respectively. The odds of exclusive snuff use, exclusive chewing tobacco, and dual use of both products for individuals with alcohol use disorder were 1.97, 2.01, and 2.99 times the odds for those without alcohol use disorder, respectively. Respondents with cannabis use disorder were 1.44 times more likely to use snuff exclusively than those without cannabis use disorder. Respondents with inhalant/solvent use disorder were associated with 3.33 times the odds of exclusive chewing tobacco. In conclusion, this study highlights the specific links of anxiety disorder, alcohol, cannabis, and inhalant/solvent use disorders with different types of smokeless tobacco use.

Case-series Evaluating a Transdiagnostic Cognitive-behavioral Treatment For Co-occurring Anxiety Disorders.

Background. Patients with anxiety disorder diagnoses commonly have more than one anxiety diagnosis. While cognitive-behavioral interventions have proven efficacy in treating single anxiety disorder diagnoses, there has been little investigation of their efficacy in treating cooccurring anxiety disorders. Aims. To evaluate the efficacy of a transdiagnostic cognitive-behavioral intervention for treating co-occurring anxiety disorders. Methods. An A-B single case study design (N = 6) was used to evaluate the efficacy of a 12 to 13 session modular transdiagnostic cognitive-behavioral intervention for treating co-occurring anxiety disorders across patients with at least two of the following diagnoses: GAD, Social Phobia, Panic Disorder and/or OCD. Results. Five of the six participants completed treatment. At post-treatment assessment the five treatment completers achieved diagnostic and symptomatic change with three participants being diagnosis free. All participants who completed treatment no longer met criteria for any DSM-IV-TR Axis-I diagnosis at the three-month follow-up assessment, and demonstrated reliable and clinically-significant improvements in symptoms. Across the participants, statistically significant improvements from pre- to post-intervention were found on measures of anxiety, depression and general well-being, and all improvements were maintained at three-month follow-up. Conclusions. Results suggest that transdiagnostic cognitive behavioral interventions can be of benefit to patients with co-occurring anxiety disorders.

Family relationships and learning experiences in anxious vs. non-anxious families: Are there differences ?

L'objectif principal de ce travail était d'explorer les relations parent-enfant et les processus d'apprentissage familiaux associés aux troubles anxieux. A cet effet, des familles ayant un membre anxieux (la mère ou l'enfant) ont été comparées avec des familles n'ayant aucun membre anxieux. Dans une première étude, l'observation de l'interaction mère-enfant, pendant une situation standardisée de jeu, a révélé que les mères présentant un trouble panique étaient plus susceptibles de se montrer verbalement contrôlantes, critiques et moins sensibles aux besoins de l'enfant, que les mères qui ne présentaient pas de trouble panique. Une deuxième étude a examiné les perceptions des différents membres de la famille quant aux relations au sein de la famille et a indiqué que, par comparaison aux adolescents non-anxieux, les adolescents anxieux étaient plus enclins à éprouver un sentiment d'autonomie individuelle diminué par rapport à leurs parents. Finalement, une troisième étude s'est intéressée à déterminer l'impact d'expériences d'apprentissage moins directes dans l'étiologie de l'anxiété. Les résultats ont indiqué que les mères présentant un trouble panique étaient plus enclines à s'engager dans des comportements qui maintiennent la panique et à impliquer leurs enfants dans ces comportements, que les mères ne présentant pas de trouble panique. En se basant sur des recherches antérieures qui ont établi une relation entre le contrôle parental, la perception de contrôle chez l'enfant et les troubles anxieux, le présent travail non seulement confirme ce lien mais propose également un modèle pour résumer l'état actuel des connaissances concernant les processus familiaux et le développement des troubles anxieux. Deux routes ont été suggérées par lesquelles l'anxiété pourrait être transmise de manière intergénérationnelle. Chacune de ces routes attribue un rôle important à la perception de contrôle chez l'enfant. L'idée est que lorsque les enfants présentent une prédisposition à interpréter le comportement de leurs parents comme hors de leur contrôle, ils seraient plus enclins à développer de l'anxiété. A ce titre, la perception du contrôle représenterait un tampon entre le comportement de contrôle/surprotection des parents et le trouble anxieux chez l'enfant. - The principal objective of the present work was to explore parent-child relationships and family learning processes associated with anxiety disorders. To this purpose, families with and without an anxious family member (mother or child) were compared. In a first study, observation of mother-child interaction, during a standard play situation, revealed that mothers with panic disorder were more likely to display verbal control and criticism, and less likely to display sensitivity toward their children than mothers without panic disorder. A second study examined family members' perceptions of family relationships and indicated that compared to non-anxious adolescents, anxious adolescents were more prone to experience a diminished sense of individual autonomy in relation to their parents. Finally a third study was interested in determining the effect of less direct learning experiences in the aetiology of anxiety. Results indicated that mothers with panic disorder were more likely to engage in panic-maintaining behaviour and to involve their children in this behaviour than mothers without panic disorder. Based on previous research showing a relationship between parental control, children's perception of control, and anxiety disorders, the present work not only further adds evidence to support this link but also proposes a model summarizing the current knowledge concerning family processes and the development of anxiety disorders. Two pathways have been suggested through which anxiety may be intergenerationally transmitted. Both pathways assign an important role to children's perception of control. The idea is that whenever children have a predisposition towards interpreting their parents' behaviour as beyond of their control, they may be more prone to develop anxiety. As such, perceived control may represent a buffer between parental overcontrolling/overprotective behaviours and childhood anxiety disorder.

L’impact d’une interaction sociale centrée sur le trauma sur la réactivité physiologique d’individus avec un état de stress post-traumatique, en fonction de leurs symptômes et de leur soutien social.

Introduction: Les personnes ayant développé un état de stress post-traumatique (ÉSPT) évitent systématiquement d’aborder avec leurs proches le sujet du trauma ainsi que tout élément y étant associé. Cette forme d’évitement peut entraver le processus naturel de rétablissement. Les hypothèses suivantes peuvent être énoncées à cet égard. Tout d’abord, une discussion avec une personne proche et centrée sur le trauma peut être vécue comme étant anxiogène et, par conséquent, provoquer une augmentation de la fréquence du rythme cardiaque, d’ailleurs communément connue sous le nom de réactivité du rythme cardiaque. La réactivité provoquée par une telle situation peut positivement varier en fonction de l’intensité des symptômes d’ÉSPT. Cette association entre les symptômes et la réactivité peut, à son tour, varier en fonction des perceptions de la personne anxieuse du soutien social de la part de son proche et/ou de son entourage. Il en va de même pour les individus ayant développé un trouble anxieux comparable, soit le trouble panique (TP). Toutefois, toutes ces hypothèses n’ayant pas été jusqu’à maintenant vérifiées empiriquement, la présente thèse a eu pour objectif de les tester. Méthodologie: Un total de 46 personnes avec un ÉSPT et de 22 personnes avec un TP ont complété des entrevues diagnostiques et des questionnaires auto-rapportés concernant leurs symptômes ainsi que leurs perceptions des interactions sociales soutenantes et non soutenantes ou négatives avec leur proche significatif et leur entourage. Elles ont également participé à une interaction sociale avec une personne proche et centrée sur leur trouble anxieux, situation qui incluait également des mesures continues du rythme cardiaque. Résultats: Les résultats ont démontré qu’une interaction sociale centrée sur le trauma avec une personne proche provoquait une augmentation significative de la fréquence du rythme cardiaque des participants en comparaison à une interaction sociale non conflictuelle et non anxiogène avec cette même personne. Cette réactivité du rythme cardiaque corrélait de façon significative et positive avec l’intensité de leurs symptômes d’ÉSPT. Les résultats ont également permis de constater que l’hypothèse de modération concernant les perceptions d’interactions sociales positives était partiellement confirmée, soit pour les symptômes d’évitement; les perceptions d’interactions sociales négatives étant quant à elles associées de façon significative et positive à cette réactivité (c.à.d. suivant un effet principal). Quant aux personnes avec un TP, une atténuation significative dans la fréquence de leur rythme cardiaque fut observée dans le contexte analogue, atténuation qui était positivement liée à la sévérité de leurs attaques de panique. Certaines dimensions de leurs perceptions de soutien social étaient significativement et négativement liées à cette atténuation (c.à.d. suivant un effet principal). Discussion: La présente thèse a notamment démontré qu’il existait des liens entre les symptômes d’ÉSPT et la réactivité du rythme cardiaque dans le contexte d’une interaction sociale avec un proche et centrée sur le trauma. Elle a également permis de constater que les symptômes d’ÉSPT et les perceptions d’interaction sociales positives et négatives peuvent prédire cette réactivité. Dans l’avenir, des devis longitudinaux pourront informer davantage à propos de la direction des liens ici explorés.

Efectos del consumo de cigarrillo en la presentación y severidad de la dismenorrea

Introducción: La dismenorrea se presenta como una patología cada vez más frecuente en mujeres de 16-30 años. Dentro de los factores asociados a su presentación, el consumo de tabaco ha revelado resultados contradictorios. El objetivo del presente estudio es explorar la asociación entre el consumo de cigarrillo y la presentación de dismenorrea, y determinar si los trastornos del ánimo y la depresión, alteran dicha asociación. Materiales y métodos: Se realizó un estudio de prevalencia analítica en mujeres de la Universidad del Rosario matriculadas en pregrado durante el primer semestre de 2013, para determinar la asociación entre el consumo de tabaco y la presentación de dismenorrea. En el estudio se tuvieron en cuenta variables tradicionalmente relacionadas con dismenorrea, incluyendo las variables ansiedad y depresión como potenciales variables de confusión. Los registros fueron analizados en el programa Estadístico IBM SPSS Statistics Versión 20.0. Resultados: Se realizaron 538 cuestionarios en total. La edad promedio fue 19.92±2.0 años. La prevalencia de dismenorrea se estimó en 89.3%, la prevalencia de tabaquismo 11.7%. No se encontró una asociación entre dismenorrea y tabaquismo (OR 3.197; IC95% 0.694-14.724). Dentro de las variables analizadas, la depresión y la ansiedad constituyen factores de riesgo independientes para la presentación de dismenorrea con una asociación estadísticamente significativa p=0.026 y p=0.024 respectivamente. El análisis multivariado encuentra como factor determinante en la presentación de dismenorrea, la interacción de depresión y ansiedad controlando por las variables tradicionales p<0.0001. Sin embargo, esta asociación se pierde cuando se analiza en la categoría de dismenorrea severa y gana relevancia el uso de métodos de anticoncepción diferentes a los hormonales, mientras que el hecho de haber iniciado la vida sexual presenta una tendencia limítrofe de riesgo. Conclusiones: No se puede demostrar que el tabaco es un factor asociado a la presentación de dismenorrea. Los trastornos del ánimo y la ansiedad constituyen factores determinantes a la presentación de dismenorrea independientemente de la presencia de otros concomitantes. Las variables de asociación se modifican cuando la variable dependiente se categoriza en su estado más severo. Se necesitan estudios más amplios y detallados para establecer dicha asociación.

Assessment and management of anxiety disorders in children and adolescents

Anxiety disorders in childhood and adolescence are extremely common and are often associated with lifelong psychiatric disturbance. Consistent with DSM-5 and the extant literature, this review concerns the assessment and treatment of specific phobias, separation anxiety disorder, generalised anxiety disorder, social anxiety disorder, panic disorder and agoraphobia. Evidence-based psychological treatments (cognitive behaviour therapy; CBT) for these disorders have been developed and investigated, and in recent years promising low-intensity versions of CBT interventions have been proposed that offer a means to increase access to evidence-based treatments. There is some evidence of effectiveness of pharmacological treatments for anxiety disorders in children and young people, however, routine prescription is not recommended due to concerns about potential harm.
