    This article examines a clinical sample of 66 Dominican and Puerto Rican subjects who reported ataques de nervios and also psychiatric disorder, and disentangles the phenomenological experiences of ataque de nervios, panic attacks, and panic disorder. In-depth cultural interviews assessed the symptomatic phenomenology of ataque episodes from the local perspective as well as in terms of key panic features, such as recurrence, rapid peaking of symptoms, and lack of provocation. Independent diagnostic assessments of panic attacks and disorder were also used to establish the phenomenological overlap between ataque and panic. Our findings indicate that 36 percent of ataques de nervios fulfill criteria for panic attacks and between 17 percent and 33 percent for panic disorder, depending on the overlap method used. The main features distinguishing ataques that fulfill panic criteria from ataques that do not include whether the episodes were provoked by an upsetting event in the person's life and the rapidity of crescendo of the actual attack. A key finding is that ataques often share individual phenomenological features with panic episodes, but that these features usually do not "run together" during the ataque experience. This confirms previous findings that ataque is a more inclusive construct than panic disorder. The importance of these findings for the clinical diagnosis and treatment of persons with ataques is discussed.

    To study the effect of playing cell phone chess game on treating panic attack. The chess game on an android cell phone was played by the researcher who was affected by panic attack as a post-traumatic disorder immediately after or before feeling of the start of symptoms. The right level of difficulty, i.e., levels 2-4, was selected for optimal results. Playing chess game on the android cell phone prevented the manifestation of panic attack and led to the cure of this traumatic condition. Chess therapy with the right level of difficulty can be recommended as a very effective non-pharmaceutical method for the successful treatment of panic attacks. Copyright © 2017 Elsevier B.V.

    To study phenomenology of attacks of atrial fibrillation (AF) and to compare it with phenomenology of panic attacks for elucidation of pathogenesis of atrial fibrillation and for elaboration of rational therapeutic intervention including those aimed at correction of psychovegetative abnormalities. Patients with nonrheumatic paroxysmal AF (n=105) and 100 patients with panic attacks (n=100). Clinical, cardiological and neurological examination, analysis of patients complaints during attacks of AF, and comparison them with diagnostic criteria for panic attack. It was found that clinical picture of attacks of AF comprised vegetative, emotional and functional neurological phenomena similar to those characteristic for panic attacks. This similarity as well as positive therapeutic effect of clonazepam allowed to propose a novel pathogenic mechanism of AF attacks. Severity of psychovegetative disorders during paroxysm of AF could be evaluated by calculation of psychovegetative iudex: Psychovegetative index should be used for detection of panic attack-like component in clinical picture of AF paroxysm and thus for determination of indications for inclusion of vegetotropic drugs, e. g. clonazepam, in complex preventive therapy.

    Full Text Available Abstract 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.

    Full Text Available A bibliographic search has been performed in MEDLINE using cortisol and panic as key-words, occurring in the title and/or in the abstract. Human studies were selected, with no time limit. The following publications were excluded: reviewarticles, case reports, panic attacks in disorders other than panic disorder, and studies on changes that occurred in-between panic attacks. The results showed that real-life panic attacks as well as those induced by selective panicogenic agents such as lactate and carbon dioxide do not activate the hypothalamicpituitary- adrenal (HPA axis. Agonists of the colecystokinin receptor B, such as the colecystokinin-4 peptide and pentagastrin, increase stress hormones regardless of the occurrence of a panic attack and thus, seem to activate the HPA axis directly. The benzodiazepine antagonist flumazenil does not increase stress hormones, but this agent does not reliably induce panic attacks. Pharmacological agents that increased anxiety in both normal subjects and panic patients raised stress hormone levels; among them are the alpha2-adrenergic antagonist yohimbine, the serotonergic agents 1-(m-chlorophenyl piperazine (mCPP and fenfluramine, as well as the psychostimulant agent caffeine. Therefore, the panic attack does not seem to activate the HPAaxis, in contrast to anticipatory anxiety.Realizou-se levantamento bibliográfico no indexadorMEDLINE, através das palavras-chave "cortisol" e "panic", sem limite de tempo, restringindo-se a sereshumanos e à localização das palavras-chave no título e no resumo.

    Full Text Available Background Panic disorder refers to the repeated or unexpected anxiety or panic attacks. It makes patients feel extreme pain. Although the episodes of most patients with panic disorder happen at daytime, the nocturnal panic attacks (NPA are quite common. Paients pay more attention to NPA. Insomnia is more serious in patients with NPA than those patients with panic disorder attack at daytime. Many patients may occur anxiety and avoidance behavior after NPA. Patients are often afraid of sleeping, or even do not sleep. The aim of this study is to analyze polysomnographic (PSG parameter changes and clinical concomitant symptoms of patietns with NPA, to explore the characteristics of sleep, in order to provide better diagnosis, differential diagnosis and treatment for these patients. Methods The features of sleep of 20 NPA patients and 23 healthy controls were monitored by video-PSG. Hamilton Anxiety Rating Scale (HAMA and Hamilton Depression Rating Scale (HAMD were used to assess the state of anxiety, depression, and dyssomnia of the patients. Results In comparison with normal control group, the NPA group showed shortened total sleep time (TST, decreased sleep efficiency (SE and sleep maintenance rate, delayed arousal time, increased number of arousal and number of arousal episode longer than 5 minutes, increased percentage of non-rapid eye movement (NREM sleep stage Ⅰ, decreased percentage of NREM sleep stageⅢ and percentage of rapid eye movement (REM sleep (P 0.05, for all. In NPA group, there were 13 cases (13/20 with anxiety, 17 (17/20 with depression, 13 cases/times (13/20 with difficulty of falling asleep, 17 cases/times (17/20 with difficulties in maintaining sleep (frequent arousals and difficult to fall asleep again and 7 cases/times (7/20 with wake up early. Conclusion NPA patients present decreased deep sleep, increased shallow sleep and poor sleep quality, and are mostly accompanied with mild or moderate depression and (or anxiety

    Empirical work has documented a robust and consistent relation between panic attacks and smoking behavior. Theoretical models posit smokers with panic attacks may rely on smoking to help them manage chronically elevated negative affect due to uncomfortable bodily states, which may explain higher levels of nicotine dependence and quit problems. The current study examined the effects of panic attack history on nicotine dependence, perceived barriers for quitting, smoking inflexibility when emotionally distressed, and expired carbon monoxide among 461 treatment-seeking smokers. A multiple mediator path model was evaluated to examine the indirect effects of negative affect and negative affect reduction motives as mediators of the panic attack-smoking relations. Panic attack history was indirectly related to greater levels of nicotine dependence (b = 0.039, CI95% = 0.008, 0.097), perceived barriers to smoking cessation (b = 0.195, CI95% = 0.043, 0.479), smoking inflexibility/avoidance when emotionally distressed (b = 0.188, CI95% = 0.041, 0.445), and higher levels of expired carbon monoxide (b = 0.071, CI95% = 0.010, 0.230) through the sequential effects of negative affect and negative affect smoking motives. The present results provide empirical support for the sequential mediating role of negative affect and smoking motives for negative affect reduction in the relation between panic attacks and a variety of smoking variables in treatment-seeking smokers. These mediating variables are likely important processes to address in smoking cessation treatment, especially in panic-vulnerable smokers.

    Full Text Available Abstract Background Because a large proportion of patients with panic attacks receiving approved pharmacotherapy do not respond or respond poorly to medication, it is important to identify additional therapeutic strategies for the management of panic symptoms. This article describes a randomized, rater-blind study comparing low-dose risperidone to standard-of-care paroxetine for the treatment of panic attacks. Methods Fifty six subjects with a history of panic attacks were randomized to receive either risperidone or paroxetine. The subjects were then followed for eight weeks. Outcome measures included the Panic Disorder Severity Scale (PDSS, the Hamilton Anxiety Scale (Ham-A, the Hamilton Depression Rating Scale (Ham-D, the Sheehan Panic Anxiety Scale-Patient (SPAS-P, and the Clinical Global Impression scale (CGI. Results All subjects demonstrated a reduction in both the frequency and severity of panic attacks regardless of treatment received. Statistically significant improvements in rating scale scores for both groups were identified for the PDSS, the Ham-A, the Ham-D, and the CGI. There was no difference between treatment groups in the improvement in scores on the measures PDSS, Ham-A, Ham-D, and CGI. Post hoc tests suggest that subjects receiving risperidone may have a quicker clinical response than subjects receiving paroxetine. Conclusion We can identify no difference in the efficacy of paroxetine and low-dose risperidone in the treatment of panic attacks. Low-dose risperidone appears to be tolerated equally well as paroxetine. Low-dose risperidone may be an effective treatment for anxiety disorders in which panic attacks are a significant component.

    Panic attacks (PAs) are characterized by overwhelming surges of fear and discomfort and are one of the most frequently occurring symptoms in psychiatric populations. The most recent version of the Diagnostic and Statistical Manual of Mental Disorders (i.e. DSM-5) allows for a panic attack (PA) specifier for all disorders, including social anxiety disorder (SAD). However, there is little research examining differences between individuals diagnosed with SAD with the PA specifier versus individuals diagnosed with SAD without the PA specifier. The current study examined social anxiety, mood, anxiety, and anxiety sensitivity social concerns, a risk factor for social anxiety in SAD-diagnosed individuals without (N = 52) and with (N = 14) the PA specifier. The groups differed only in somatic symptoms of anxiety. Result of the current study provides preliminary evidence that the presence of the PA specifier in social anxiety does not result in elevated levels of comorbidity or a more severe presentation of social anxiety.

    In this study we examined how personality disposition may affect the response to cholecystokinin tetrapeptide (CCK-4; 50 microg) challenge in healthy volunteers (n=105). Personality traits were assessed with the Swedish universities Scales of Personality (SSP). Statistical methods employed were correlation analysis and logistic regression. The results showed that the occurrence of CCK-4-induced panic attacks was best predicted by baseline diastolic blood pressure, preceding anxiety and SSP-defined traits of lack of assertiveness, detachment, embitterment and verbal aggression. Significant interactions were noted between the above mentioned variables, modifying their individual effects. For different subsets of CCK-4-induced symptoms, the traits of physical aggression, irritability, somatic anxiety and stress susceptibility also appeared related to panic manifestations. These findings suggest that some personality traits and their interactions may influence vulnerability to CCK-4-induced panic attacks in healthy volunteers. Copyright 2010 Elsevier Ireland Ltd.

  13. Ventilatory control of heart rate during inhalation of 5% CO2 and types of panic attacks.

    Differences in the magnitude of increases in heart rate during prolonged inhalation of 5% CO2 range from a mean of 25 b/min for a group of eight panic-disorder patients who panicked (Woods, Charney, Goodman, & Heninger, 1988. Archives of General Psychiatry, 45, 43-52) to zero b/min for 16 patients, eight of whom panicked (Craske & Barlow, 1990. Journal of Abnormal Psychology, 99, 302-307). What accounts for this disparity? The present paper describes how heart rate can be increased by means of voluntary overbreathing during prolonged inhalation of 5% CO2 in air. This suggests that differences in the degree of overbreathing may explain differences in the magnitude of increases in heart rate during inhalation of 5% CO2. An explanation is also offered for the curious finding that some patients experience "panic attacks" with zero increase in heart rate. Evidence suggests that this is likely to happen in cognitively based panic attacks, in contrast to hyperventilatory attacks or anticipatory attacks.

  14. Interoceptive fear learning to mild breathlessness as a laboratory model for unexpected panic attacks

    Full Text Available Fear learning is thought to play an important role in panic disorder. Benign interoceptive sensations can become predictors (conditioned stimuli - CSs of massive fear when experienced in the context of an initial panic attack (unconditioned stimulus – US. The mere encounter of these CSs on a later moment can induce anxiety and fear, and precipitate a new panic attack. It has been suggested that fear learning to interoceptive cues would result in unpredictable panic. The present study aimed to investigate whether fear learning to an interoceptive CS is possible without declarative knowledge of the CS-US contingency. The CS consisted of mild breathlessness (or: dyspnea, the US was a suffocation experience. During acquisition, the experimental group received 6 presentations of mild breathlessness immediately followed by suffocation; for the control group both experiences were always separated by an intertrial interval. In the subsequent extinction phase, participants received 6 unreinforced presentations of the CS. Expectancy of the US was rated continuously and startle eyeblink EMG, skin conductance and respiration were measured. Declarative knowledge of the CS-US relationship was also assessed with a post-experimental questionnaire. At the end of acquisition, both groups displayed the same levels of US expectancy and skin conductance in response to the CS, but the experimental group showed a fear potentiated startle eyeblink and a different respiratory response to the CS compared to the control group. Further analyses on a subgroup of CS-US unaware participants confirmed the presence of startle eyeblink conditioning in the experimental group but not in the control group. Our findings suggest that interoceptive fear learning is not dependent on declarative knowledge of the CS-US relationship. The present interoceptive fear conditioning paradigm may serve as an ecologically valid laboratory model for unexpected panic attacks.

    While chronobiological studies have reported seasonal variation in panic attacks (PA) episodes, information on the timing of PA by week-days may enable better understanding of the triggers of PA episodes and thereby provide pointers for suitable interventional approaches to minimize PA attacks. This study investigated weekly variation in potential PA admissions including associations with holidays using a population-based longitudinal, administrative claims-based dataset in an Asian population. This study used ambulatory care data from the "Longitudinal Health Insurance Database 2000. We identified 993 patients with panic disorder (PD), and they had 4228 emergency room (ER) admissions for potential PA in a 3-year period between 1 January 2009 and 31 December 2011. One-way analysis of variance (ANOVA) was used to examine associations between the potential PA admissions and holidays/weekend days/work-days of the week. The daily mean number of potential PA admissions was 3.96 (standard deviation 2.05). One-way ANOVA showed significant differences in potential PA admissions by holiday and day of the week (pholidays. Furthermore, the weekly variations were similar for females and males, although females always had higher potential PA admissions on both weekdays and holidays than the males. We found that potential PA admissions among persons with PD varied systematically by day of the week, with a significant peak on weekends and holidays.

    Panic disorder is a chronic and debilitating illness. In this article, we present an algorithm of the diagnosis and treatment of the illness. We place much importance upon the patient variables associated with the treatment decisions. We emphasize strong patient involvement in treatment as a way to become panic free and improve level of functioning. Panic disorder is defined in DSM-IV1 as "The presence of recurrent panic attacks followed by at least one month of persistent concern about having another panic attack, worry about the possible implications or consequences of the panic attack, or a significant behavioral change related to the attacks." A panic attack is defined as "a discrete period of intense fear or discomfort, in which four or more of the following symptoms developed abruptly and reached a peak within 10 minutes." 1) Palpitations, pounding heart or accelerated heart rate; 2) sweating; 3) trembling or shaking; 4) sensations of shortness of breath or smothering; 5) feeling of choking; 6) chest pain or discomfort; 7) nausea or abdominal distress; 8) feeling dizzy, unsteady, light-headed or faint; 9) derealization or depersonalization; 10) fear of losing control or going crazy; 11) fear of dying; 12) paresthesias; 13) chills or hot flashes. The following hypotheses have been used to conceptualize panic disorder from a psychiatrist's perspective.

    2010-04-01

    We propose some reflexions on the validity of the conceptualization of panic disorder, its nosographical place, and its clinical homogeneity, through the study of the frequency of some of its psychiatric comorbidities. To define a panic attack, DSM IV requires a number of symptoms which vary from four to 13. However, some patients suffer from panic attacks with less than four symptoms (paucisymptomatic attacks) and which fill the other criteria of panic disorder. These patients would have a biological vulnerability, familial antecedents, and a treatment response which are similar to those that fill the criteria of the panic attack according to the DSM. Some authors differentiate the panic disorder in several sub-groups, such as the panic disorder with cardiorespiratory symptoms, or vestibular symptoms, or cognitive symptoms. This division of the panic disorder in several sub-groups would have an interest in the knowledge of the etiopathogeny, the attacks' frequency, the disorder severity and the treatment response. Panic disorder with prevalent somatic expression includes crises without cognitive symptoms. This sub-type can be common in the medical context, especially in cardiology, but it is often ignored, at the price of loss of socio-professional adaptability, and a medical overconsumption. The relationship between panic disorder and agoraphobia appears to be the subject of controversies. According to the behavioral theory, phobic disorder is the primum movens of the sequence of appearance of the disorders. American psychiatry considers agoraphobia as a secondary response to the panic disorder, and pleads for a central role of panic attacks as an etiopathogenic factor in the development of agoraphobia. The distinction between panic disorder and generalized anxiety disorder can be difficult. This is due to the existence of paucisymptomatic panic attacks. Their paroxystic nature is difficult to distinguish from the fluctuations of the generalized anxiety disorder

    Full Text Available Abstract Background The place where a patient experiences his/her first panic attack (FPA may be related to their agoraphobia later in life. However, no investigations have been done into the clinical features according to the place where the FPA was experienced. In particular, there is an absence of detailed research examining patients who experienced their FPA at home. In this study, patients were classified by the location of their FPA and the differences in their clinical features were explored (e.g., symptoms of FPA, frequency of agoraphobia, and severity of FPA. Methods The subjects comprised 830 panic disorder patients who were classified into 5 groups based on the place of their FPA (home, school/office, driving a car, in a public transportation vehicle, outside of home, The clinical features of these patients were investigated. Additionally, for panic disorder patients with agoraphobia at their initial clinic visit, the clinical features of patients who experienced their FPA at home were compared to those who experienced their attack elsewhere. Results In comparison of the FPAs of the 5 groups, significant differences were seen among the 7 descriptors (sex ratio, drinking status, smoking status, severity of the panic attack, depression score, ratio of agoraphobia, and degree of avoidance behavior and 4 symptoms (sweating, chest pain, feeling dizzy, and fear of dying. The driving and public transportation group patients showed a higher incidence of co-morbid agoraphobia than did the other groups. Additionally, for panic disorder patients with co-morbid agoraphobia, the at-home group had a higher frequency of fear of dying compared to the patients in the outside-of-home group and felt more severe distress elicited by their FPA. Conclusion The results of this study suggest that the clinical features of panic disorder patients vary according to the place of their FPA. The at-home group patients experienced "fear of dying" more frequently

    The Diagnostic and Statistical Manual of Mental Disorders [DSM-IV-TR; American Psychiatric Association [APA], 2000) has emphasized the importance of understanding psychopathology within a cultural framework by including culture-bound syndromes within its appendices. These syndromes are proposed to be bound to certain cultures and distinct from other psychological disorders. Included among the syndromes are ataques de nervios (ADN), which are reported to be bound to the Hispanic culture and closely resemble panic attacks. However, the cultural distinctiveness and phenomenology of ADN has not been adequately investigated. The current study employed an ethnically diverse study sample (N=342) of undergraduates. Participants completed a number of measures that assessed acculturation, syndrome and anxiety risk factors. In contrast to the DSM-IV's conceptualization of ADN, the rate of ADN did not significantly vary across the three main groups (African American, Caucasian, and Hispanic participants) nor did it vary based on acculturation. More consistent with the DSM-IV, the symptom comparisons indicated some differentiation between ADN and panic attacks. The present report provides data indicating that ADNs, as described by the DSM-IV, are not unique to the Hispanic culture and are experienced by non-Hispanic individuals at similar rates to Hispanic-endorsement. The findings are consistent with the DSM-IV assertion that ADNs and PAs are distinct syndromes. (c) 2008 Wiley-Liss, Inc.

    Full Text Available Introduction: The mitral valve prolapse is a heart syndrome that is characterized by considerable physical and psychological consequences for affected patients. This study aimed to assess the efficacy of cognitive-behavioral therapy in reducing worrying, generalized anxiety and panic attacks in patients with mitral valve prolapse. Methods: This study is quasi-experimental research with pretest-posttest and control group. 16 patients with mitral valve prolapse divided into to two groups: experimental (n = 8 and control (n = 8 groups. CBT was used during 10 sessions twice a week with a focus on cognitive restructuring, modification of cognitive distortions and training of behavioral techniques for the experimental group. For participants health  concerns spot and doush (HCQ, Generalized anxiety disorder (GAD- 7 and Albania panic scales as pre-test, post-test. Results: Data were analyzed by covariance analysis. The results showed that worrying, anxiety, and panic attacks significantly reduced in the experimental group. Discussion: Cognitive behavioral therapy is remarkably effective for reducing fear, anxiety and panic patients with mitral valve prolapse. Therefore, it is recommended for the patients with mitral valve prolapse that cognitive behavioral therapy can be used as a complementary therapy.

    This study aimed to investigate associations of job stressors with panic attack (PA) and panic disorder (PD) among Japanese workers. A cross-sectional online questionnaire survey was conducted of 2060 workers. Job strain, effort/reward imbalance, and workplace social support were measured by the job content questionnaire and effort/reward imbalance questionnaire. These variables were classified into tertiles. PA/PD were measured by self-report based on the mini international neuropsychiatric interview (MINI). Multiple logistic regression was conducted, adjusting for demographic, lifestyle, and health-related covariates. Data from 1965 participants were analyzed. Adjusted odds ratio (OR) of PA/PD was significantly greater for the group with high effort/reward imbalance compared with the group with low effort/reward imbalance (ORs, 2.64 and 2.94, respectively, both P imbalance was associated with having PA/PD among Japanese workers.

    To explore the effects of Chinese medicine prescription Zuogui Pill (, ZGP) on monoamine neurotransmitters and sex hormones in climacteric rats with induced panic attacks. Forty-eight climacteric female rats were randomized into 6 groups with 8 rats in each group: the control group, the model group, the low-, medium- and high-dose ZGP groups and the alprazolam group. Rats in the low-, medium- and high-dose ZGP groups were administered 4.725, 9.45, or 18.9 g/kg ZGP by gastric perfusion, respectively. The alprazolam group was treated by gastric perfusion with 0.036 mg/kg alprazolam. The control and model groups were treated with distilled water. The animals were pretreated once daily for 8 consecutive weeks. The behaviors of rats in the open fifield test and the elevated T-maze (ETM) were observed after induced panic attack, and the levels of brain monoamine neurotransmitters and the plasma levels of sex hormones were measured. Compared with the control group, the mean ETM escape time and the levels of 5-hydroxytryptamine (5-HT) and noradrenalin (NE) of the model group were signifificantly reduced (P<0.05), Compared with the model group, the mean ETM escape time and the 5-HT and NE levels of all the ZGP groups increased signifificantly (P<0.05 or P<0.01). However, no signifificant difference was observed in the levels of sex hormones between the groups. Pretreatment with ZGP in climacteric rats may improve the behavior of panic attack, which may be related to increased 5-HT and NE in the brain.

In clinical practice, panic disorder manifests with isolated gastroenteric or cardiovascular symptoms, requiring additional clinical visits after psychiatric intervention. The first-line treatment for anxiety disorders, and in particular for panic disorder, is the selective serotonin reuptake inhibitors. However, these drugs can have adverse effects, including sexual dysfunction, increased bodyweight, and abnormal bleeding, that may be problematic for some patients. Here we report the case of a 29-year-old Caucasian woman affected by panic disorder with agoraphobia who was referred to our clinic for recurrent gastroenteric panic symptoms. The patient reported improvement in her anxiety symptoms and panic attacks while on a selective serotonin reuptake inhibitor, but not in her gastric somatic problems, so the decision was taken to start her on duloxetine, a serotonin-norepinephrine reuptake inhibitor. After 6 months of treatment, the patient achieved complete remission of her gastric and panic-related symptoms, and was able to stop triple gastric therapy. Other authors have hypothesized and confirmed that duloxetine has greater initial noradrenergic effects than venlafaxine and is effective in patients with panic disorder. This case report underscores the possibility of tailoring therapeutic strategies for the gastroenteric expression of panic disorder. Keywords: anxiety disorder, panic

    This paper refers to the relationship between panic and agoraphobia, regarding Panic Disorder and Agoraphobia (DSM IV), from two different points of view coming from Psychoanalysis and Psychiatry. Psychoanalysis (S. Freud) considers agoraphobia as a defensive organization to avoid anxiety, not bound to the original conflict, but to substitutive formation. The exposure to space (its unconscious significance) provokes panic attack. The psychiatric approach considers agoraphobia, meaningless by its own, as a consequence of spontaneous panic attacks. The etiology is referred to neurophysiological mechanisms. The authors reviewd D Klein's hypothesis about panic and Freud's theories on anxiety, partiularly Anxiety Neurosis.

    Electroencephalographic (EEG) findings repeatedly reported abnormal synchronous or even epileptiform discharges in panic disorder. Although less frequently occurring in patients with panic disorder, these deviant EEG features during panic attacks were also observed in intracranial EEG. For this purpose, our article reviews the consideration of abnormal synchronous neuronal activity in different neurocircuits, particularly limbic, as a suggested condition of panic attacks. Therapeutic approaches of anticonvulsants have shown reductions of symptoms and frequency of attacks in numerous patients suffering from panic disorder, supporting the presumption of underlying abnormal synchronous neuronal activity. Thus, scalp EEG recordings are still recommended for discovering indications of abnormal synchronous neuronal activity in panic patients.

    Full Text Available OBJECTIVE: To assess the effectiveness of clonazepam, in a fixed dose (2 mg/day, compared with placebo in the treatment of panic disorder patients. METHOD: 24 panic disorder patients with agoraphobia were randomly selected. The diagnosis was obtained using the structured clinical interview for DSM-IV . All twenty-four subjects were randomly assigned to either treatment with clonazepam (2 mg/day or placebo, during 6 weeks. Efficacy assessments included: change from baseline in the number of panic attacks; CGI scores for panic disorder; Hamilton rating scale for anxiety; and panic associated symptoms scale. RESULTS: At the therapeutic endpoint, only one of 9 placebo patients (11.1% were free of panic attacks, compared with 8 of 13 (61.5% clonazepam patients (Fisher exact test; p=0,031. CONCLUSION: the results provide evidence for the efficacy of clonazepam in panic disorder patients.

    Ataque de nervios ("attack of nerves") is an illness category used frequently by Hispanic individuals to describe one or more particular symptom complexes. A review of the literature on ataque suggested some overlap with panic disorder. This study investigated the overlap with panic disorder as well as other DSM-III-R axis I disorders. Hispanic subjects seeking treatment at an anxiety disorders clinic (N = 156) were assessed with a specially designed questionnaire for self-report of ataque de nervios and panic symptoms and with structured or semistructured psychiatric interviews for axis I disorders. Seventy percent of the subjects reported at least one ataque de nervios; 80% of these were female, whereas 57% of the group without these attacks were female. There were no differences in DSM-III-R diagnoses between the groups with and without ataque de nervios. Ataque was frequently associated with one or more anxiety and affective disorders, including panic disorder, generalized anxiety disorder, recurrent major depression, and anxiety not otherwise specified. Of the 45 subjects with both ataque de nervios and primary panic disorder, 80% appeared to have labeled panic disorder as ataque. Ataque de nervios was associated with panic symptoms even in subjects without panic disorder, but the self-reporting of ataque conveyed additional clinical information about the subjects with panic disorder. Ataque de nervios was similar in frequency and symptoms among subjects of Dominican and Puerto Rican origin. Ataque de nervios overlaps with panic disorder but is a more inclusive construct. Further study of its interrelation with axis I disorders is needed.

  8. New perspective on the pathophysiology of panic: merging serotonin and opioids in the periaqueductal gray

    2012-04-01

    Full Text Available Panic disorder patients are vulnerable to recurrent panic attacks. Two neurochemical hypotheses have been proposed to explain this susceptibility. The first assumes that panic patients have deficient serotonergic inhibition of neurons localized in the dorsal periaqueductal gray matter of the midbrain that organize defensive reactions to cope with proximal threats and of sympathomotor control areas of the rostral ventrolateral medulla that generate most of the neurovegetative symptoms of the panic attack. The second suggests that endogenous opioids buffer normal subjects from the behavioral and physiological manifestations of the panic attack, and their deficit brings about heightened suffocation sensitivity and separation anxiety in panic patients, making them more vulnerable to panic attacks. Experimental results obtained in rats performing one-way escape in the elevated T-maze, an animal model of panic, indicate that the inhibitory action of serotonin on defense is connected with activation of endogenous opioids in the periaqueductal gray. This allows reconciliation of the serotonergic and opioidergic hypotheses of panic pathophysiology, the periaqueductal gray being the fulcrum of serotonin-opioid interaction.

    Panic disorder is a severe anxiety disorder characterized by recurrent panic attacks that can be consistently provoked with intravenous (i.v.) infusions of hypertonic (0.5 M) sodium lactate (NaLac), yet the mechanism/CNS site by which this stimulus triggers panic attacks is unclear. Chronic inhibition of GABAergic synthesis in the dorsomedial hypothalamus/perifornical region (DMH/PeF) of rats induces a vulnerability to panic-like responses after i.v. infusion of 0.5 M NaLac, providing an animal model of panic disorder. Using this panic model, we previously showed that inhibiting the anterior third ventricle region (A3Vr; containing the organum vasculosum lamina terminalis, the median preoptic nucleus, and anteroventral periventricular nucleus) attenuates cardiorespiratory and behavioral responses elicited by i.v. infusions of NaLac. In this study, we show that i.v. infusions of 0.5 M NaLac or sodium chloride, but not iso-osmolar D-mannitol, increased 'anxiety' (decreased social interaction) behaviors, heart rate, and blood pressure responses. Using whole-cell patch-clamp preparations, we also show that bath applications of NaLac (positive control), but not lactic acid (lactate stimulus) or D-mannitol (osmolar stimulus), increases the firing rates of neurons in the A3Vr, which are retrogradely labeled from the DMH/PeF and which are most likely glutamatergic based on a separate study using retrograde tracing from the DMH/PeF in combination with in situ hybridization for vesicular glutamate transporter 2. These data show that hypertonic sodium, but not hyper-osmolarity or changes in lactate, is the key stimulus that provokes panic attacks in panic disorder, and is consistent with human studies.

    Context The scarcity of cross-national reports and the changes in DSM-5 regarding panic disorder (PD) and panic attacks (PAs) call for new epidemiological data on PD and PAs and its subtypes in the general population. Objective To present representative data about the cross-national epidemiology of PD and PAs in accordance with DSM-5 definitions. Design and Setting Nationally representative cross-sectional surveys using the World Health Organization Composite International Diagnostic Interview version 3.0. Participants Respondents (n=142,949) from 25 high, middle and lower-middle income countries across the world aged 18 years or older. Main Outcome Measures PD and presence of single and recurrent PAs. Results Lifetime prevalence of PAs was 13.2% (s.e. 0.1%). Among persons that ever had a PA, the majority had recurrent PAs (66.5%; s.e. 0.5%), while only 12.8% fulfilled DSM-5 criteria for PD. Recurrent PAs were associated with a subsequent onset of a variety of mental disorders (OR 2.0; 95% CI 1.8–2.2) and their course (OR 1.3; 95% CI 1.2–2.4) whereas single PAs were not (OR 1.1; 95% CI 0.9–1.3 and OR 0.7; 95% CI 0.6–0.8). Cross-national lifetime prevalence estimates were 1.7% (s.e. 0.0%) for PD with a median age of onset of 32 (IQR 20–47). Some 80.4% of persons with lifetime PD had a lifetime comorbid mental disorder. Conclusions We extended previous epidemiological data to a cross-national context. The presence of recurrent PAs in particular is associated with subsequent onset and course of mental disorders beyond agoraphobia and PD, and might serve as a generic risk marker for psychopathology.

    Full Text Available OBJECTIVE: We aim to determine if a treatment with a dose of clonazepam - 2 mg/day, for 6 weeks, blocks spontaneous panic attacks and the ones induced by the inhalation of 35% carbon dioxide (CO2 in panic disorder (PD patients. The CO2 challenge-test may be a useful addition tool for measuring the pharmacological response during the initial phase (6 weeks in the treatment of PD. METHOD: Eighteen PD patients drug free for a week participated in a carbon dioxide challenge test. Fourteen had a panic attack and were openly treated for a 6-week period with clonazepam. At the end of the 6-week period they were submitted again to the CO2 challenge test. RESULTS: After 6 weeks of treatment with clonazepam, 12 of 14 PD patients (85.7% did not have a panic attack after the CO2 challenge test. Just 2 of 14 patients (14.3% had a panic attack after the CO2 challenge test. Ten of 14 (71.4% PD patients had panic free status after clonazepam treatment. The 2 patients who had a panic attack in the sixth week, after the CO2 test, did not have panic free status after the treatment with clonazepam. CONCLUSION: The CO2-test may be a valid tool for testing and predicting the drug response.

    This systematic review aimed to examine the results of studies that have investigated the induction of panic attacks and/or the anxiogenic effect of the caffeine challenge test in patients with panic disorder. The literature search was performed in PubMed, Biblioteca Virtual em Saúde and the ISI Web of Knowledge. The words used for the search were caffeine, caffeine challenge test, panic disorder, panic attacks and anxiety disorder. In total, we selected eight randomized, double-blind studies where caffeine was administered orally, and none of them controlled for confounding factors in the analysis. The percentage of loss during follow-up ranged between 14.3% and 73.1%. The eight studies all showed a positive association between caffeine and anxiogenic effects and/or panic disorder.

    The present study investigated the efficacy of a coping-technique, applied relaxation (AR) and cognitive behavior therapy (CBT), in the treatment of panic disorder. Thirty-eight outpatients fulfilling the DSM-III-R criteria for panic disorder with no (n = 30) or mild (n = 8) avoidance were assessed with independent assessor ratings, self-report scales and self-observation of panic attacks before and after treatment, and at a 1-yr follow-up. The patients were treated individually for 12 weekly sessions. The results showed that both treatments yielded very large improvements, which were maintained, or furthered at follow-up. There was no difference between AR and CBT on any measure. The proportion of panic-free patients were 65 and 74% at post-treatment, and 82 and 89% at follow-up, for AR and CBT, respectively. There were no relapses at follow-up, on the contrary 55% of the patients who still had panic attacks at post-treatment were panic-free at follow-up. Besides affecting panic attacks the treatments also yielded marked and lasting changes on generalized anxiety, depression and cognitive misinterpretations. The conclusion that can be drawn is that both AR and CBT are effective treatments for panic disorder without avoidance.

OBJECTIVES: To evaluate the clinical efficacy of clonazepam in a fixed dosage (2 mg/day, compared to placebo, in the treatment of panic disorder patients and to verify whether there are any differences in the responses to clonazepam between panic disorder patients with the respiratory and non-respiratory subtypes. TYPE OF STUDY: Randomized study with clonazepam and placebo. SETTING: Outpatient Anxiety and Depression Unit of the Institute of Psychiatry, Universidade Federal do Rio de Janeiro, Rio de Janeiro, Brazil. PARTICIPANTS: 34 patients with a diagnosis of panic disorder with agoraphobia, between 18 and 55 years old. PROCEDURES: Administration of clonazepam or placebo for 6 weeks, in panic disorder patients, after they were classified within two subtypes of panic disorder: respiratory and non-respiratory. MAIN MEASUREMENTS: Changes in the number of panic attacks in comparison with the period before the beginning of the study; Hamilton Anxiety Scale; Global Clinical Impression Scale; and Patient's Global Impression scale. RESULTS: In the group that received clonazepam, by the end of the 6th week there was a statistically significant clinical improvement, shown by the remission of panic attacks (p < 0.001 and decrease in anxiety (p = 0.024. In the group that received clonazepam there was no significant difference between the respiratory and non-respiratory subtypes of panic disorder, regarding the therapeutic response to clonazepam. CONCLUSION: Clonazepam was equally effective in the treatment of the respiratory and non-respiratory subtypes of panic disorder, suggesting there is no difference in the therapeutic response between the two subtypes.

    Panic disorders (PD) which develop in the context of different psychiatric diseases (neurotic, personality disorder and schizotypal disorders) have their own clinical and neurophysiological features. The results of compressive-spectral analysis of EEG (CSA EEG) in patients with panic attack were different depending on the specifics of initial psychiatric status. EEG parameters in patients differed from those in controls. The common feature for all PD patients was the lower spectral density of theta-, alpha- and beta-bands as well as total spectral density without any alterations of region distribution. The decrease of electrical activity of activation systems was found in the groups with neurotic and schizotypal disorders and that of inhibition systems - in the group with schizotypal disorders. The EEG results did not suggest any depression of activation systems in patients with specific personality disorders. The data obtained with CSA EEG mirror the integrative brain activity which determinad of the appearance of PA as well as of nosology of psychiatre disease.

    Because panic disorder has an underlying biologic and probably genetic basis, the role of factors outside the organism in initiating and sustaining panic is often overlooked. The authors review certain exogenous factors that seem capable of triggering attacks and/or increasing their frequency and intensity: self-administered pharmacologic agents (caffeine, alcohol, nicotine, over-the-counter cold preparations, cannabis, cocaine); habits (sleep deprivation, diet, exercise, relaxation, hyperventilation); and aspects of the environment (fluorescent lighting, life stressors). There may be a specificity to the action of some of these factors, because certain factors previously thought to trigger panic attacks (e.g., pain, hypoglycemia) have been proved not to have this effect. Although the clinical significance of many of the exogenous factors discussed still awaits empirical confirmation, attention to such factors during the initial evaluation of a patient with panic disorder may be helpful in formulating a successful treatment plan.

The sample consisted of 119 patients, 32 men (26.9% and 87 women (73.1% with the basic diagnosis of agoraphobia with panic disorder. All the patients were evaluated with the clinical instruments suitable for the assessment of various clinical features associated with agoraphobia with panic disorder - questionnaires (the Hopkins Symptom Checklist 90, the Panic Appraisal Inventory, the Fear Questionnaire, the Beck Anxiety Inventory, and the Beck Depression Inventory, and the clinical rating scale (the Panic and Agoraphobia Scale. After the data collection, the sample was divided into two groups by the gender. Then the groups were compared. Results. There were no differences between the genders in the global psychopathologic features (the age at the onset of a disorder, duration of a disorder, severity and frequency of panic attacks, intensity of general psychiatric symptoms, intensity of general anxiety and depression. The women, however, reported a subjective perception of a more severe agoraphobic avoidance and males were significantly more likely than the females to anticipate the serious somatic consequences of panic attacks and worry about somatic health. Conclusion. There were a few gender specific psychopathologic features in patients with agoraphobia with panic disorder, so further studies would be necessary to come to a more precise conclusion.

    The aim of the study was to compare the treatment of panic disorder in patients with or without cannabis use according to response, relapse and side effects. 66 panic disorder (PD) patients were included in our study. All the subjects met the DSM-IV diagnosis of panic disorder (n=45) or panic disorder with agoraphobia (n=21). Twenty four patients experienced their first panic attack within 48 h of cannabis use and then went on to develop PD. All the patients received pharmacologic treatment with paroxetine (gradually increased up to 40 mg/d). A masked rater that was blind to the group allocation, assessed patients in order to rate anxiety symptoms and medication side effects. Relapse was defined as the occurrence of a single panic attack after remission of panic symptoms. The instruments were administered at baseline and also at the 4, 8 and 12 weeks visits and at the 1 year visit. The two groups responded equally well to paroxetine treatment as measured at the 8 weeks and 12 months follow-up visits. There were no significant effects of age, sex and duration of illness as covariates with response rates between the two groups. Also PD or PDA diagnosis did not affect the treatment response in either group. There were no significant differences in weight gain, sexual side effects or relapse rates between patients according to gender or comorbid diagnosis. Acute cannabis use can be associated with the onset of panic attacks and panic disorder, and panic disorder which develops after cannabis use is responsive to pharmacotherapy.

    Panic disorder is an anxiety disorder that involves recurrent panic attacks, which emerge when a harmless stimulus is interpreted as "catastrophic". In an attempt to avoid the panic attack or prevent confrontation, the patient exhibits a dysfunctional attitude and behavior, such as evasion and safety-seeking behavior (SSB). Dysfunctional behavior leads to an increase in the recurrence of panic attacks and affects the patient's life in a negative way. According to the cognitive behavioral therapy model, SSB contributes to the continuation of unrealistic beliefs (e.g. physical experiences) regarding and prevents the patient from grasping new information that may potentially contradict the unrealistic cognitions. In this paper, we present a case with a primary diagnosis of panic disorder. Interestingly, this patient developed diabetes mellitus (DM) type 2 and psychogenic polydipsia (PPD) as a consequence of his SSB. PPD is a common occurrence in patients with psychiatric disorders, especially in schizophrenia. Up to now, no case of a panic disorder with either DM or PPD has been reported in the literature. While it is accepted that major depression poses a risk for DM type 2, panic disorder may also increase this risk. Treatment of the panic disorder with cognitive behavioral therapy (CBT) resulted in improvement of PPD and DM type 2. In conclusion, the role of SSB in medical disorders accompanied by psychiatric disorders should be kept in mind when treating these patients.

To determine if a ten days treatment with clonazepam attenuates the panic attacks induced by the inhalation of 35% carbon dioxide in panic disorder. METHOD: We randomly selected six panic disorder subjects, using the Structured Clinical Interview for DSM-IV. All subjects went double-blindly through an inhalation of 35% CO2 and compressed gas (atmospheric air on two occasions. First, at baseline, when they were drug free. Second, after a 10 days clonazepam treatment. RESULTS: Neither at baseline nor after treatment any patient had a panic attack during compressed gas inhalation. At the first test five patients (83.3% had a severe panic attack with high levels of subjective anxiety during carbon dioxide inhalation. After 9.6 (± 3.4 days of clonazepam treatment, only two (33.3% patients experienced a mild panic attack. CONCLUSION: This pilot study suggests the efficacy of the short term clonazepam therapy in attenuating panic attacks and supports the usefulness of the 35% carbon dioxide challenge test as an analogue method for study the efficacy of anti-panic drugs. Further placebo-controlled studies to pharmacological treatment are warranted.OBJETIVOS: 1.

  6. Evaluation of JNJ-54717793 a Novel Brain Penetrant Selective Orexin 1 Receptor Antagonist in Two Rat Models of Panic Attack Provocation

    Full Text Available Orexin neurons originating in the perifornical and lateral hypothalamic area are highly reactive to anxiogenic stimuli and have strong projections to anxiety and panic-associated circuitry. Recent studies support a role for the orexin system and in particular the orexin 1 receptor (OX1R in coordinating an integrative stress response. However, no selective OX1R antagonist has been systematically tested in two preclinical models of using panicogenic stimuli that induce panic attack in the majority of people with panic disorder, namely an acute hypercapnia-panic provocation model and a model involving chronic inhibition of GABA synthesis in the perifornical hypothalamic area followed by intravenous sodium lactate infusion. Here we report on a novel brain penetrant, selective and high affinity OX1R antagonist JNJ-54717793 (1S,2R,4R-7-([(3-fluoro-2-pyrimidin-2-ylphenylcarbonyl]-N-[5-(trifluoromethylpyrazin-2-yl]-7-azabicyclo[2.2.1]heptan-2-amine. JNJ-54717793 is a high affinity/potent OX1R antagonist and has an excellent selectivity profile including 50 fold versus the OX2R. Ex vivo receptor binding studies demonstrated that after oral administration JNJ-54717793 crossed the blood brain barrier and occupied OX1Rs in the rat brain. While JNJ-54717793 had minimal effect on spontaneous sleep in rats and in wild-type mice, its administration in OX2R knockout mice, selectively promoted rapid eye movement sleep, demonstrating target engagement and specific OX1R blockade. JNJ-54717793 attenuated CO2 and sodium lactate induced panic-like behaviors and cardiovascular responses without altering baseline locomotor or autonomic activity. These data confirm that selective OX1R antagonism may represent a novel approach of treating anxiety disorders, with no apparent sedative effects.

    This review covers the literature since the publication of DSM-IV on the diagnostic criteria for panic attacks (PAs) and panic disorder (PD). Specific recommendations are made based on the evidence available. In particular, slight changes are proposed for the wording of the diagnostic criteria for PAs to ease the differentiation between panic and surrounding anxiety; simplification and clarification of the operationalization of types of PAs (expected vs. unexpected) is proposed; and consideration is given to the value of PAs as a specifier for all DSM diagnoses and to the cultural validity of certain symptom profiles. In addition, slight changes are proposed for the wording of the diagnostic criteria to increase clarity and parsimony of the criteria. Finally, based on the available evidence, no changes are proposed with regard to the developmental expression of PAs or PD. This review presents a number of options and preliminary recommendations to be considered for DSM-V.

  8. Hypophosphatemia. From retrospective analysis to the analysis of the potential role of phosphatemia in panic disorders

    Full Text Available The detection of a low serum phosphate level is not unusual in an Emergency Department, especially in clinical conditions linked to hyperventilation and subsequent respiratory alkalosis, asthma, sepsis, severe pain, anxiety. Symptoms of hypophosphatemia are typically not specific when the imbalance is not particularly severe, but if hyphophosphatemia does not resolve rhabdomyolisis, hemolysis, decreased tissue oxygenation and respiratory failure can be observed. Only recently some authors have pointed out that the level of serum phosphate in patient with anxiety and panic disorders can give information on the severity of the attacks as well on the clinical course of the disease. In a retrospective analysis on 599 case of hypophosphatemia observed in our ED, the percentage of case of panic disorders was particularly high among patients with lower phosphatemia. Therefore, we decided to examine this aspect closely, assessing if the determination of serum phosphate could be useful in the management of panic attacks at first approach in emergency room. Our observation are consistent with the statement that hypophosphatemia is one of the main clinical aspect of panic attack, and strongly support the hypothesis that hypophosphatemia correlates with the most severe symptoms of panic attack and should be itself considered as one of the most important aspect of this syndrome. Serum phosphate levels appear to mirror its clinical course, and can be used in the clinical setting of an Emergency Department, for the confirmation of a diagnosis of anxiety-panic disorder and as marker of the response to therapy

  9. How study of respiratory physiology aided our understanding of abnormal brain function in panic disorder.

    There is a substantial body of literature demonstrating that stimulation of respiration (hyperventilation) is a common event in panic disorder patients during panic attack episodes. Further, a number of abnormalities in respiration, such as enhanced CO2 sensitivity, have been detected in panic patients. This led some to posit that there is a fundamental abnormality in the physiological mechanisms that control breathing in panic disorder and that this abnormality is central to illness etiology. More recently, however, evidence has accumulated suggesting that respiratory physiology is normal in panic patients and that their tendency to hyperventilate and to react with panic to respiratory stimulants like CO2 represents the triggering of a hypersensitive fear network. The fear network anatomy is taken from preclinical studies that have identified the brain pathways that subserve the acquisition and maintenance of conditioned fear. Included are the amygdala and its brain stem projections, the hippocampus, and the medial prefrontal cortex. Although attempts to image this system in patients during panic attacks have been difficult, the theory that the fear network is operative and hyperactive in panic patients explains why both medication and psychosocial therapies are clearly effective. Studies of respiration in panic disorder are an excellent example of the way in which peripheral markers have guided researchers in developing a more complete picture of the neural events that occur in psychopathological states.

  10. Anxiety and panic: from human studies to animal research and back.

    The role of learning and conditioning varies across human anxiety disorders, and distinguishing between fear and panic is important to guide investigation in panic disorder. By reminding that some psychological and psychobiological theories view panic attacks as false alarms of unconditioned biological origin, we suggest that employing endophenotypes of biological and evolutionary relevance--such as the respiratory responses to suffocative stimuli--can be fruitful for both human research and animal models of panic, and can help keeping unconditioned components of the clinical picture separate from the conditioned components in the experimental setting. We present a review of a model of panic disorder by which idiosyncratic environmental adverse events can promote unconditioned and unexpected spells of physical alarm. Along the proposed causal pathway the alternative splicing expression of polymorphic genes of the cholinergic system play an important role. The overproduction of the Acetylcholinesterase readthrough splice variant after minor stress can promote passive avoidance and learning through action at the level of the corticolimbic circuitries, as well as heightened sensitivity to suffocative stimuli by action upon the cholinergic components of chemoception. When a component of anticipatory anxiety complicates the clinical picture of recurrent panic attacks, and the HPA becomes activated, the glucocorticoid response element 17 kb upstream of the Acetylcholinesterase gene transcription initiation site may sustain sensitivity to suffocative stimuli for prolonged time. Finally, we review how animal models of human panic based on unconditioned provocation of alarm reactions by the same respiratory panicogens that are employed in man are viable and promising.

    Cognitive models of panic disorder suggest that change in catastrophic misinterpretations of bodily sensations will predict symptom reduction. To examine change processes, we used a repeated measures design to evaluate whether the trajectory of change in misinterpretations over the course of 12-week cognitive behavior therapy is related to the trajectory of change in a variety of panic-relevant outcomes. Participants had a primary diagnosis of panic disorder (N = 43; 70% female; mean age = 40.14 years). Race or ethnicity was reported as 91% Caucasian, 5% African American, 2.3% biracial, and 2.3% "other." Change in catastrophic misinterpretations (assessed with the Brief Body Sensations Interpretation Questionnaire; Clark et al., 1997) was used to predict a variety of treatment outcomes, including overall panic symptom severity (assessed with the Panic Disorder Severity Scale [PDSS]; Shear et al., 1997), panic attack frequency (assessed with the relevant PDSS item), panic-related distress/apprehension (assessed by a latent factor, including peak anxiety in response to a panic-relevant stressor-a straw breathing task), and avoidance (assessed by a latent factor, which included the Fear Questionnaire-Agoraphobic Avoidance subscale; Marks & Mathews, 1979). Bivariate latent difference score modeling indicated that, as expected, change in catastrophic misinterpretations predicted subsequent reductions in overall symptom severity, panic attack frequency, distress/apprehension, and avoidance behavior. However, change in the various symptom domains was not typically a significant predictor of later interpretation change (except for the distress/apprehension factor). These results provide considerable support for the cognitive model of panic and speak to the temporal sequence of change processes during therapy. (c) 2010 APA, all rights reserved.

    The effect of the cognitive behavioral therapy (CBT) for panic disorder varies, but how personality disorder functioning style influences it remains unclear. In 30 healthy volunteers and 44 patients with panic disorder (22 treated and 22 waiting list), we administered the Parker Personality Measure (PERM) and the Plutchik-van Praag Depression Inventory (PVP). Before and during the CBT or waiting period, patients were asked to record their panic attacks using the Panic Attack Record (PAR). Patients scored significantly higher on PERM Antisocial, Borderline, Histrionic, Avoident, Dependent, and Passive-aggressive styles and on depression. After CBT, all PAR parameters were significantly reduced in the treated group. The Obsessive-compulsive style was positively correlated with the panic attack duration and the total-thought before CBT or waiting period in all patients. In treated patients, the decreased panic attack duration was positively correlated with Histrionic, Obsessive-compulsive and Passive-aggressive; the decreased total symptom number was positively correlated with Antisocial and Histrionic; the decreased total-sensation was positively correlated with antisocial; and the total-thought was positively correlated with Narcissistic style. The length and duration of CBT was short and mainly with behavioral strategies, how personality influenced the related cognition per se remains unknown here. However, our preliminary results indicate that personality disorder functioning styles related to the externalized behaviors and the Obsessive-compulsive style have positive effects on CBT for panic disorder, implying that CBT practitioners should note their personality styles when treating these patients.

    A dimensional and psychometrically informed taxonomy of anxiety is emerging, but the specific and nonspecific dimensions of panic and phobic anxiety require greater clarification. In this study, confirmatory factor analyses of data from a sample of 438 college students were used to validate a model of panic and phobic anxiety with six content factors; multiple scales from self-report measures were indicators of each model component. The model included a nonspecific component of (1) neuroticism and two specific components of panic attack, (2) physiological hyperarousal, and (3) anxiety sensitivity. The model also included three phobia components of (4) classically defined agoraphobia, (5) social phobia, and (6) blood-injection phobia. In these data, agoraphobia correlated more strongly with both the social phobia and blood phobia components than with either the physiological hyperarousal or the anxiety sensitivity components. These findings suggest that the association between panic attacks and agoraphobia warrants greater attention.

    Full Text Available Objective: To compare patients with panic disorder with agoraphobia treated with cognitive-behavioural therapy (CBT associated with the medication with patients treated only with medication and verify the behaviour of the cardio-respiratory symptoms of both groups. Methods: Randomized sample in the Psychiatry Institute of the Federal University of Rio de Janeiro, divided in two groups of 25 participants each. Group 1 undertook 10 weekly sessions of CBT with one hour of duration each together with medication. Group 2, Control, were administered medication that only consisted of tricyclic anti-depressants and selective inhibitors of the re-uptake of serotonin. Evaluation instruments were applied at the beginning and to the end of the interventions. Results: According to the applied scales, group 1 showed statistically more significant results than group 2, with: reduction of panic attacks, cardio-respiratory symptoms, anticipatory anxiety, agoraphobia avoidance and fear of bodily sensations. Conclusion: Exposures (in vivo and interoceptive, especially for induction symptom exercises and relaxation, were considered essential to prepare patients with panic disorder to handle future cardio-respiratory symptoms and panic attacks with agoraphobia.

    Childhood separation anxiety disorder (SAD) is hypothesized to share etiologic roots with panic disorder. The aim of this study was to estimate the genetic and environmental sources of covariance between childhood SAD and adult onset panic attacks (AOPA), with the primary goal to determine whether these two phenotypes share a common genetic diathesis. Participants included parents and their monozygotic or dizygotic twins (n = 1,437 twin pairs) participating in the Virginia Twin Study of Adolescent Behavioral Development and those twins who later completed the Young Adult Follow-Up (YAFU). The Child and Adolescent Psychiatric Assessment was completed at three waves during childhood/adolescence followed by the Structured Clinical Interview for DSM-III-R at the YAFU. Two separate, bivariate Cholesky models were fit to childhood diagnoses of SAD and overanxious disorder (OAD), respectively, and their relation with AOPA; a trivariate Cholesky model also examined the collective influence of childhood SAD and OAD on AOPA. In the best-fitting bivariate model, the covariation between SAD and AOPA was accounted for by genetic and unique environmental factors only, with the genetic factor associated with childhood SAD explaining significant variance in AOPA. Environmental risk factors were not significantly shared between SAD and AOPA. By contrast, the genetic factor associated with childhood OAD did not contribute significantly to AOPA. Results of the trivariate Cholesky reaffirmed outcomes of bivariate models. These data indicate that childhood SAD and AOPA share a common genetic diathesis that is not observed for childhood OAD, strongly supporting the hypothesis of a specific genetic etiologic link between the two phenotypes. © 2012 Wiley Periodicals, Inc.

    The epidemiology of panic disorder is well known, but data about some phenomenological aspects are sparse. The symptom criteria for panic disorder were developed largely from rational expert consensus methods and not from empirical research. This fact calls attention to the construct validity of the panic disorder diagnosis, which may affect accuracy of epidemiological findings. Seventy self-identified Non-Hispanic-Caucasian (Anglo) and Hispanic-Caucasian (Hispanic) people who were diagnosed with DSM-III-R panic disorder with or without agoraphobia were invited to complete a Panic Phenomenological Questionnaire (PPQ), which was constructed for this study from the Hamilton Anxiety Scale Items and The DSM-III-R panic symptoms. Fifty (71%) subjects agreed to participate, and there was no response bias detected. Seven symptoms on the PPQ that are not in the DSM-IV diagnostic criteria were reported to occur with a high prevalence in this study. Furthermore, many symptoms that occurred with a high frequency and were reported to be experienced as severe are also not included in current nosology. A few of the DSM-IV criterion symptoms occurred with low prevalence, frequency, and severity. Cognitive symptoms were reported to occur with higher frequency and severity during attacks than autonomic or other symptoms. There were modest differences between ethnic groups with regard to panic attack phenomena. Further research using multiple empirical methods aimed at improving the content validity of the panic disorder diagnosis is warranted. This includes utilizing consistent methods to collect data that will allow for rational decisions about how to construct valid panic disorder criteria across cultures.

    Among 148 patients presenting Panic Disorder (DSM-III-R), 18.9% have an alcohol disorder, 8.8% present abuse and 10.1% dependence. Mean age of onset of alcoholism was much earlier than panic disorder. Patients with alcoholism: a) are males more frequently (0.001); b) present more alcoholism in first grade relatives (0.05); c) use more often other drugs like: tobacco (0.01), coffee (p cannabis (p < 0.001), d) patients with alcoholism refer a greater severity of their panic attacks when drinking large amounts of alcohol (25%) than the group without these problems (2.5%) (x2:14.8) (p < 0.001) e) according to the GAS the overall level of performance is lower in alcoholics (p < 0.005); f) present more anxiety measured by the HARS (p < 0.01), and therefore have more comorbid anxiety disorders according to DSM-III-R (p < 0.01). The clinical significance of these findings is discussed.

    To compare the efficacy of clomipramine hydrochloride (CMI), a serotonin reuptake inhibitor with the noradrenergic tricyclic antidepressant agent, and desipramine hydrochloride (DMI) for patients with panic disorder (PD). Following a 2-week, single-blind placebo washout phase, 17 PD outpatients completed a 16-week, double-blind, crossover comparison of CMI and DMI. Key outcome measures included panic attacks frequency, the NIMH Global Scales for Anxiety, Depression and Impairment, Hamilton Anxiety Scale (Psychic and Somatic Subscales), Zung Anxiety Inventory (Raw and Index Subscales) and the Spielberger State Anxiety Scale. Both CMI and DMI led to significant improvement from baseline placebo state in panic attacks frequency and behavioral ratings (p<0.001). CMI led to a greater reduction in the frequency of panic attacks (p=0.028) and was superior to DMI on ratings of anxiety: NIMH Global Anxiety, Zung Anxiety Scale (Raw and Index) and the Spielberger Anxiety Scale. No difference was found between the drugs on the NIMH Global Impairment Scale and the Hamilton Somatic and Psychic Scales. Both drugs appeared to have significant therapeutic effects in patients with PD, but CMI appeared to be more effective. The effectiveness of the serotonergic drug suggests that the role of the serotonergic system in the pathogenesis of PD should be further explored.

    Full Text Available The objective of the present randomized, open-label, naturalistic 8-week study was to compare the efficacy and safety of treatment with clonazepam (N = 63 and paroxetine (N = 57 in patients with panic disorder with or without agoraphobia. Efficacy assessment included number of panic attacks and clinician ratings of the global severity of panic disorders with the clinical global impression (CGI improvement (CGI-I and CGI severity (CGI-S scales. Most patients were females (69.8 and 68.4% in the clonazepam and paroxetine groups, respectively and age (mean ± SD was 35.9 ± 9.6 years for the clonazepam group and 33.7 ± 8.8 years for the paroxetine group. Treatment with clonazepam versus paroxetine resulted in fewer weekly panic attacks at week 4 (0.1 vs 0.5, respectively; P < 0.01, and greater clinical improvements at week 8 (CGI-I: 1.6 vs 2.9; P = 0.04. Anxiety severity was significantly reduced with clonazepam versus paroxetine at weeks 1 and 2, with no difference in panic disorder severity. Patients treated with clonazepam had fewer adverse events than patients treated with paroxetine (73 vs 95%; P = 0.001. The most common adverse events were drowsiness/fatigue (57%, memory/concentration difficulties (24%, and sexual dysfunction (11% in the clonazepam group and drowsiness/fatigue (81%, sexual dysfunction (70%, and nausea/vomiting (61% in the paroxetine group. This naturalistic study confirms the efficacy and tolerability of clonazepam and paroxetine in the acute treatment of patients with panic disorder.

    2014-10-01

    The present paper is the edited version of our presentations at the "First World Symposium On Translational Models Of Panic Disorder", in Vitoria, E.S., Brazil, on November 16-18, 2012. We also review relevant work that appeared after the conference. Suffocation-False Alarm Theory (Klein, 1993) postulates the existence of an evolved physiologic suffocation alarm system that monitors information about potential suffocation. Panic attacks maladaptively occur when the alarm is erroneously triggered. The expanded Suffocation-False Alarm Theory (Preter and Klein, 2008) hypothesizes that endogenous opioidergic dysregulation may underlie the respiratory pathophysiology and suffocation sensitivity in panic disorder. Opioidergic dysregulation increases sensitivity to CO2, separation distress and panic attacks. That sudden loss, bereavement and childhood separation anxiety are also antecedents of "spontaneous" panic requires an integrative explanation. Our work unveiling the lifelong endogenous opioid system impairing effects of childhood parental loss (CPL) and parental separation in non-ill, normal adults opens a new experimental, investigatory area.

    Full Text Available This case describes a 31-year-old female Caucasian patient with complaints of ongoing depression, agitation, and severe panic attacks. The patient was untreated until a recent unsuccessful trial of citalopram followed by venlafaxine which produced a partial response. Genetic testing was performed to assist in treatment decisions and revealed the patient to be heterozygous for polymorphisms in 5HT2C, ANK3, and MTHFR and homozygous for a polymorphism in SLC6A4 and the low activity (Met/Met COMT allele. In response to genetic results and clinical presentation, venlafaxine was maintained and lamotrigine was added leading to remission of agitation and depression.

    The aim of the study was to investigate whether polymorphisms in the preproghrelin gene are associated with anxiety disorders, such as panic disorder, in humans. Panic disorder is a severe anxiety disorder, characterized by sudden attacks of intense fear or anxiety in combination with somatic symptoms. The preproghrelin gene codes for two gut-derived circulating peptides that have been linked to anxiety-like behaviour in rodents: ghrelin (an orexigenic, pro-obesity hormone) and obestatin. In the present study, we genotyped three missense mutations in the preproghrelin gene in 215 patients suffering from panic disorder and in 451 controls. The A allele of the rs4684677 polymorphism was significantly associated with panic disorder, while there were no significant associations with the two other polymorphisms studied. We conclude that the rs4684677 (Gln90Leu) polymorphism in the preproghrelin gene may be associated with increased risk of panic disorder. It will be important to confirm these findings in additional panic disorder patient groups. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

    Consecutive Cambodian refugees attending a psychiatric clinic were assessed for the presence and severity of current--i.e., at least one episode in the last month--neck-focused panic. Among the whole sample (N=130), in a logistic regression analysis, the Anxiety Sensitivity Index (ASI; odds ratio=3.70) and the Clinician-Administered PTSD Scale (CAPS; odds ratio=2.61) significantly predicted the presence of current neck panic (NP). Among the neck panic patients (N=60), in the linear regression analysis, NP severity was significantly predicted by NP-associated flashbacks (beta=.42), NP-associated catastrophic cognitions (beta=.22), and CAPS score (beta=.28). Further analysis revealed the effect of the CAPS score to be significantly mediated (Sobel test [Baron, R. M., & Kenny, D. A. (1986). The moderator-mediator variable distinction in social psychological research: conceptual, strategic, and statistical considerations. Journal of Personality and Social Psychology, 51, 1173-1182]) by both NP-associated flashbacks and catastrophic cognitions. In the care of traumatized Cambodian refugees, NP severity, as well as NP-associated flashbacks and catastrophic cognitions, should be specifically assessed and treated.

    2002-01-01

    The aim of our study was to evaluate the effectiveness of a self-information booklet (SIB) in decreasing anxiety and panic attacks in Panic Disorder (PD) patients. Eighty-four patients attending an outpatient clinic due to panic disorder were randomly chosen to receive paroxetine with/without a friendly-designed brochure. Follow-up was done by a masked rater after 1, 3,and 12 weeks in order to evaluate whether the co-administration of paroxetine and the brochure (Group A) had a beneficial effect over the administration of paroxetine alone (Group B). After 3 weeks of therapy, Group A patients had significantly greater improvement and lower scores on the Hamilton Anxiety Scale, the Panic Self Questionnaire, and the Visual Analog Scale. After 12 weeks, the differential improvement was not statistically significant and both groups had improved as compared to baseline. The administration of a psychoeducational brochure (SIB) to PD patients at the initiation of therapy had beneficial effects during the first weeks of treatment. Although this effect fades away, the role of the SIB is overstressed in its ability to increase well being and compliance, and reduce anxiety and panic attacks. Copyright 2002 Wiley-Liss, Inc.

    Multiple respiratory abnormalities can be found in anxiety disorders, especially in panic disorder (PD). Individuals with PD experience unexpected panic attacks, characterized by anxiety and fear, resulting in a number of autonomic and respiratory symptoms. Respiratory stimulation is a common event during panic attacks. The respiratory abnormality most often reported in PD patients is increased CO2 sensitivity, which has given rise to the hypothesis of fundamental abnormalities in the physiological mechanisms that control breathing in PD. There is evidence that PD patients with dominant respiratory symptoms are more sensitive to respiratory tests than are those who do not manifest such symptoms, and that the former group constitutes a distinct subtype. Patients with PD tend to hyperventilate and to panic in response to respiratory stimulants such as CO2, triggering the activation of a hypersensitive fear network. Although respiratory physiology seems to remain normal in these subjects, recent evidence supports the idea that they present subclinical abnormalities in respiration and in other functions related to body homeostasis. The fear network, composed of the hippocampus, the medial prefrontal cortex, the amygdala and its brain stem projections, might be oversensitive in PD patients. This theory might explain why medication and cognitive-behavioral therapy are both clearly effective. Our aim was to review the relationship between respiration and PD, addressing the respiratory subtype of PD and the hyperventilation syndrome, with a focus on respiratory challenge tests, as well as on the current mechanistic concepts and the pharmacological implications of this relationship.

    Panic disorder is one of the most common anxiety disorders and has a lifetime prevalence of 3-5%. Panic attacks can begin at any age, but commonly have their onset in early adulthood between the ages of 20 and 40 years. Naturalistic data has shown that panic disorder has a chronic and relapsing course. Panic disorder is reported to be associated with an increased risk of suicidal behavior and comorbid psychiatric diagnoses such as depression and substance abuse. Currently, recommended treatment modalities for panic disorder include the use of antidepressant pharmacotherapy and/or cognitive behavioral therapy. Paroxetine is unique among the selective serotonin reuptake inhibitors since, in addition to its effect on the CNS serotonergic neurotransmission, it also has mild noradrenergic properties demonstrated to be effective in the treatment of anxiety disorders and depression. Paroxetine treatment has the potential to cause weight gain and sexual dysfunction, primarily anorgasmia and ejaculatory dysfunction for the long term. In the short-term, treatment causes nausea, gastrointestinal disturbances, irritability, headaches and eating and sleeping difficulties. Paroxetine is an example of an selective serotonin reuptake inhibitor agent, which has been well studied in the treatment of panic disorder and is efficacious and well-tolerated. Paroxetine pharmacotherapy has been recommended to be continued for 1 year as specified in the treatment guidelines set by the American Psychiatric Association in the treatment of panic disorder.

    Posttraumatic stress disorder (PTSD) frequently co-occurs with panic spectrum problems. Relatively little empirical work has tested possible mechanisms accounting for this association. Nicotine dependence often ensues subsequent to PTSD onset and research suggests smoking high numbers of cigarettes daily may lead to panic problems. The current study tested the hypotheses that nicotine dependence partially mediates the relations between PTSD and both panic attacks and panic disorder within a nationally representative sample of 5,692 (3,020 women; M(Age) = 45, SD = 18) adults from the National Comorbidity Survey-Replication. Results were consistent with hypotheses. These findings support the theory suggesting smoking among people with PTSD may be involved in the development of panic problems.

    Starting perhaps in the second century BCE, and with Hippocratic precedent, ancient medical writers described a condition they called hysterike pnix or "uterine suffocation." This paper argues that uterine suffocation was, in modern terms, a functional somatic syndrome characterized by chronic anxiety and panic attacks. Transcultural psychiatrists have identified and described a number of similar panic-type syndromes in modern populations, and a plausible theory of how they work has been advanced. These insights, applied to the ancient disease of hysterike pnix, demystify the condition and illuminate the experience of the women who suffered from it. © The Author 2014.

    Full Text Available Panic disorder is a highly prevalent neuropsychiatric disorder that shows co-occurrence with substance abuse. Here, we demonstrate that TrkC, the high affinity receptor for neurotrophin-3, is a key molecule involved in panic disorder and opiate dependence, using a transgenic mouse model (TgNTRK3. Constitutive TrkC overexpression in TgNTRK3 mice dramatically alters spontaneous firing rates of locus coeruleus neurons and the response of the noradrenergic system to chronic opiate exposure, possibly related to the altered regulation of neurotrophic peptides observed. Notably, TgNTRK3 locus coeruleus neurons showed an increased firing rate in saline-treated conditions and profound abnormalities in their response to met5-enkephalin. Behaviorally, chronic morphine administration induced a significantly increased withdrawal syndrome in TgNTRK3 mice. In conclusion, we show here that the NT-3/TrkC system is an important regulator of neuronal firing in locus coeruleus and could contribute to the adaptations of the noradrenergic system in response to chronic opiate exposure. Moreover, our results indicate that TrkC is involved in the molecular and cellular changes in noradrenergic neurons underlying both panic attacks and opiate dependence and support a functional endogenous opioid deficit in panic disorder patients.

    Full Text Available Personality disorders are common in subjects with panic disorder. Personality disorders have shown to affect the course of panic disorder. The purpose of this study was to examine which personality disorders effect clinical severity in subjects with panic disorder. This study included 122 adults (71 female, 41 male, who met DSM-IV criteria for panic disorder (with or without agoraphobia. Clinical assessment was conducted by using the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I, the Structured Clinical Interview for DSM-IV Axis II Personality Disorders (SCID-II and the Panic and Agoraphobia Scale (PAS, Global Assessment Functioning Scale (GAF, Beck Depression Inventory (BDI, and State-Trait Anxiety Inventory (STAI. Patients who had a history of sexual abuse were assessed with Sexual Abuse Severity Scale. Logistic regressions were used to identify predictors of suicide attempts, suicidal ideation, agoraphobia, different panic attack symptoms, sexual abuse, and early onset of disorders. The rates of comorbid Axis I and Axis II psychiatric disorders were 80.3% and 33.9%, consecutively, in patients with panic disorder. Panic disorder patients with comorbid personality disorders had more severe anxiety, depression and agoraphobia symptoms, and had earlier ages of onset, and lower levels of functioning. The rates of suicidal ideation and suicide attempts were 34.8% and 9.8%, consecutively, in subjects with panic disorder. The rate of patients with panic disorder had a history of childhood sexual abuse was 12.5%. The predictor of sexual abuse was more than one comorbid Axis II diagnosis. The predictors of suicide attempt were comorbid paranoid and borderline personality disorders, and the predictor of suicidal ideation was major depressive disorder in subjects with panic disorder. In conclusion, this study documents that comorbid personality disorders increase the clinical severity of panic disorder. Patients with more than one

    It has been proposed that highly individualistic cultures confer vulnerability to depersonalization. To test this idea, we carried out a comprehensive systematic review of published empirical studies on panic disorder, which reported the frequency of depersonalization/derealization during panic attacks. It was predicted that the frequency of depersonalization would be higher in Western cultures and that a significant correlation would be found between the frequency of depersonalization and individualism scores of the participant countries. As predicted, the frequency of depersonalization during panic was significantly lower in nonwestern countries. There was also a significant correlation between frequency of depersonalization and Individualism (rho = 0.68, p individualism. These findings are interpreted in light of recent studies suggesting that individualistic cultures are characterized by hypersensitivity to threat and by an external locus of control. Two features may be relevant in the genesis of depersonalization.

    We previously demonstrated that carbon dioxide inhalation could induce panic anxiety in a group of rare lesion patients with focal bilateral amygdala damage. To further elucidate the amygdala-independent mechanisms leading to aversive emotional experiences, we retested two of these patients (B.G. and A.M.) to examine whether triggering palpitations and dyspnea via stimulation of non-chemosensory interoceptive channels would be sufficient to elicit panic anxiety. Participants rated their affective and sensory experiences following bolus infusions of either isoproterenol, a rapidly acting peripheral β-adrenergic agonist akin to adrenaline, or saline. Infusions were administered during two separate conditions: a panic induction and an assessment of cardiorespiratory interoception. Isoproterenol infusions induced anxiety in both patients, and full-blown panic in one (patient B.G.). Although both patients demonstrated signs of diminished awareness for cardiac sensation, patient A.M., who did not panic, reported a complete lack of awareness for dyspnea, suggestive of impaired respiratory interoception. These findings indicate that the amygdala may play a role in dynamically detecting changes in cardiorespiratory sensation. The induction of panic anxiety provides further evidence that the amygdala is not required for the conscious experience of fear induced via interoceptive sensory channels. We found that monozygotic twins with focal bilateral amygdala lesions report panic anxiety in response to intravenous infusions of isoproterenol, a β-adrenergic agonist similar to adrenaline. Heightened anxiety was evident in both twins, with one twin experiencing a panic attack. The twin who did not panic displayed signs of impaired cardiorespiratory interoception, including a complete absence of dyspnea sensation. These findings highlight that the amygdala is not strictly required for the experience of panic anxiety, and suggest that neural systems beyond the amygdala are also

    Anxiety has been linked to onset of cardiovascular disease. This study examines the differential impact of types of anxiety (panic, phobia and worry) on 3-year onset of non-fatal cardiovascular disease (CVD). By investigating anxiety disorders as opposed to anxiety symptoms and by using a reliable diagnostic instrument to assess anxiety, limitations of previous studies are considered. 5149 persons at risk for CVD were interviewed using the Composite International Diagnostic Interview. The panic-type included panic disorder and panic attacks; the phobic-type included agoraphobia and social phobia, and the worry-type included generalized anxiety disorder. CVD was self-reported and required treatment or monitoring by a doctor. Analyses were adjusted for sociodemographics, behavioral variables, and comorbid somatic and psychiatric disorders. During follow-up, 62 persons (1.2%) developed CVD. Baseline generalized anxiety disorder was strongly associated with onset of CVD (adjusted OR: 3.39). Further research should replicate findings and focus on biological underpinnings of this association. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Full Text Available The aim of the present study was to verify the sensitivity to the carbon dioxide (CO2 challenge test of panic disorder (PD patients with respiratory and nonrespiratory subtypes of the disorder. Our hypothesis is that the respiratory subtype is more sensitive to 35% CO2. Twenty-seven PD subjects with or without agoraphobia were classified into respiratory and nonrespiratory subtypes on the basis of the presence of respiratory symptoms during their panic attacks. The tests were carried out in a double-blind manner using two mixtures: 1 35% CO2 and 65% O2, and 2 100% atmospheric compressed air, 20 min apart. The tests were repeated after 2 weeks during which the participants in the study did not receive any psychotropic drugs. At least 15 of 16 (93.7% respiratory PD subtype patients and 5 of 11 (43.4% nonrespiratory PD patients had a panic attack during one of two CO2 challenges (P = 0.009, Fisher exact test. Respiratory PD subtype patients were more sensitive to the CO2 challenge test. There was agreement between the severity of PD measured by the Clinical Global Impression (CGI Scale and the subtype of PD. Higher CGI scores in the respiratory PD subtype could reflect a greater sensitivity to the CO2 challenge due to a greater severity of PD. Carbon dioxide challenges in PD may define PD subtypes and their underlying mechanisms.

  7. Radiological attacks and accidents. Medical consequences

    Probability of the occurrence of radiological attacks appears to be elevated after the terrorist attacks against the United States on September 11 in 2001. There are a lot of scenarios of radiological attack: simple radiological device, radiological disperse device (RDD or dirty bomb), attacks against nuclear reactor, improvised nuclear device, and nuclear weapons. Of these, RDD attack is the most probable scenario, because it can be easily made and can generate enormous psychological and economic damages. Radiological incidents are occurring to and fro in the world, including several cases of theft to nuclear facilities and unsuccessful terrorist attacks against them. Recently, a former Russian spy has allegedly been killed using polonium-210. In addition, serious radiological accidents have occurred in Chernobyl, Goiania, and Tokai-mura. Planning, preparation, education, and training exercise appear to be essential factors to cope with radiological attacks and accidents effectively without feeling much anxiety. Triage and psychological first aid are prerequisite to manage and provide effective medial care for mass casualties without inducing panic. (author)

    Jeyce Willig Quintino-dos-Santos

    Full Text Available Plenty of evidence suggests that childhood separation anxiety (CSA predisposes the subject to adult-onset panic disorder (PD. As well, panic is frequently comorbid with both anxiety and depression. The brain mechanisms whereby CSA predisposes to PD are but completely unknown in spite of the increasing evidence that panic attacks are mediated at midbrain's dorsal periaqueductal gray matter (DPAG. Accordingly, here we examined whether the neonatal social isolation (NSI, a model of CSA, facilitates panic-like behaviors produced by electrical stimulations of DPAG of rats as adults. Eventual changes in anxiety and depression were also assessed in the elevated plus-maze (EPM and forced-swimming test (FST respectively. Male pups were subjected to 3-h daily isolations from post-natal day 2 (PN2 until weaning (PN21 allotting half of litters in individual boxes inside a sound-attenuated chamber (NSI, n = 26 whilst siblings (sham-isolated rats, SHAM, n = 27 and dam were moved to another box in a separate room. Non-handled controls (CTRL, n = 18 remained undisturbed with dams until weaning. As adults, rats were implanted with electrodes into the DPAG (PN60 and subjected to sessions of intracranial stimulation (PN65, EPM (PN66 and FST (PN67-PN68. Groups were compared by Fisher's exact test (stimulation sites, likelihood ratio chi-square tests (stimulus-response threshold curves and Bonferroni's post hoc t-tests (EPM and FST, for P<0.05. Notably, DPAG-evoked panic-like responses of immobility, exophthalmus, trotting, galloping and jumping were markedly facilitated in NSI rats relative to both SHAM and CTRL groups. Conversely, anxiety and depression scores either did not change or were even reduced in neonatally-handled groups relative to CTRL, respectively. Data are the first behavioral evidence in animals that early-life separation stress produces the selective facilitation of panic-like behaviors in adulthood. Most importantly, results implicate

    The present study investigated the effect of autogenic training-based behavioral treatment for panic disorder and identified the predictors of treatment outcome. Thirty-four patients meeting DSM-III-R criteria for panic disorder received autogenic training-based behavioral treatment from October 1981 to December 1994. They were treated individually by the author. The medical records of the patients were investigated for the purpose of this study. The results showed that this autogenic training-based behavioral treatment had successful results. Fifteen patients were cured, nine much improved, five improved, and five unchanged at the end of the treatment. Improvement trends were found as for the severity of panic attack and the severity of agoraphobic avoidance. No consistent findings about predictors emerged when such pretreatment variables as demographics and severity of symptoms were used to predict the outcome. Also, three treatment variables showed useful predictive power. First, practicing the second standard autogenic training exercise satisfactorily predicted better outcomes. Second, application of in vivo exposure was found to be positively associated with the treatment outcome in patients with agoraphobic avoidance. Third, longer treatment periods were associated with better outcomes. These findings suggested that the autogenic training-based behavioral treatment could provide relief to the majority of panic disorder patients.

    In acute respiratory alkalosis, the severity of alkalaemia is ameliorated by a decrease in plasma [HCO(3)(-)] of 0.2 mEq/L for each 1 mmHg decrease in PaCO(2). Although hyperventilation in panic disorder patients is frequently encountered in outpatients, the drop in plasma [HCO(3)(-)] sometimes surpasses the expectation calculated from the above formula. The quantitative relationship between reduced PaCO(2) and plasma [HCO(3)(-)] in acute respiratory alkalosis has not been studied in panic disorder patients. Our objective was to provide reference data for the compensatory metabolic changes in acute respiratory alkalosis in panic disorder patients. In 34 panic disorder patients with hyperventilation attacks, we measured arterial pH, PaCO(2), plasma [HCO(3)(-)] and lactate on arrival at the emergency room. For each decrease of 1 mmHg in PaCO(2), plasma [HCO(3)(-)] decreased by 0.41 mEq/L. During hypocapnia, panic disorder patients exhibited larger increases in serum lactate levels (mean +/- SD; 2.59 +/- 1.50 mmol/L, range; 0.78-7.78 mmol/L) than previously reported in non-panic disorder subjects. Plasma lactate accumulation was correlated with PaCO(2) (P respiratory alkalosis is exaggerated by increased lactic acid production in panic disorder patients. Here, we call attention to the diagnosis of acid-base derangements by means of plasma [HCO(3)(-)] and lactate concentration in panic disorder patients.

    To investigate the impact of childhood trauma on the clinical course of panic disorder and possible contributing factors. Longitudinal data of 539 participants with a current panic disorder were collected from the Netherlands Study of Depression and Anxiety (NESDA). Childhood trauma was assessed with a structured interview and clinical course after 2 years with a DSM-IV-based diagnostic interview and the Life Chart Interview. At baseline, 54.5% reported childhood trauma, but this was not predictive of persistence of panic disorder. Emotional neglect and psychological abuse were associated with higher occurrence of anxiety disorders other than panic disorder (social phobia) and with higher chronicity of general anxiety symptoms (anxiety attacks or episodes and avoidance). Baseline clinical features (duration and severity of anxiety and depressive symptoms) and personality traits (neuroticism and extraversion) accounted for roughly 30-60% of the total effect of childhood trauma on chronicity of anxiety symptoms and on occurrence of other anxiety disorders. After two years, childhood trauma is associated with chronicity of anxiety symptoms and occurrence of social phobia, rather than persistence of panic disorder. These relationships are partially accounted for by duration and severity of anxiety and depressive symptoms, and neuroticism and extraversion. © 2017 John Wiley & Sons A/S.

    Selective serotonin reuptake inhibitors (SSRIs) are currently the first-line treatment for panic disorder, although up to 30% of patients either do not respond to SSRIs or withdraw due to adverse events. Reboxetine, a selective norepinephrine reuptake inhibitor (selective NRI), is effective in treating depression and may alleviate depression-related anxiety. This study aimed to investigate the efficacy of reboxetine in the treatment of patients with panic disorder who did not respond to SSRIs. In this 6-week, open-label study, 29 adult outpatients with panic disorder who had previously failed to respond to SSRI treatment received reboxetine 2 mg/day, titrated to a maximum of 8 mg/day over the first 10 days. Efficacy was assessed using the Panic Self-Questionnaire (PSQ), the Hamilton Rating Scale for Anxiety (HAM-A), the 17-item Hamilton Rating Scale for Depression (HRSD) and the Global Assessment of Functioning (GAF) Scale. The 24 patients who completed the study responded well to reboxetine treatment. Significant improvement (p < 0.001) was observed in the number of daily panic attacks, and on the scales measuring anxiety, depression and functioning. Reboxetine was generally well tolerated. Five patients withdrew due to adverse events. Reboxetine appears to be effective in the treatment of SSRI-refractory panic disorder patients and warrants further clinical investigation.

    Full Text Available Background: Research on anger attacks has been mostly limited to depression, and only a few studies have focused on anger attacks in obsessive compulsive disorder. Materials and Methods: In a cross-sectional study all new obsessive compulsive disorder patients aged 20-60 years attending an outpatient clinic were assessed using the anger attack questionnaire, irritability, depression and anxiety scale (for the direction of the aggressive behavior and quality of life (QOL. Results: The sample consisted of 42 consecutive subjects with obsessive compulsive disorder, out of which 21 (50% had anger attacks. The obsessive compulsive disorder subjects with and without anger attacks did not show significant differences in terms of sociodemographic variables, duration of illness, treatment, and family history. However, subjects with anger attacks had significantly higher prevalence of panic attacks and comorbid depression. Significantly more subjects with anger attacks exhibited aggressive acts toward spouse, parents, children, and other relatives in the form of yelling and threatening to hurt, trying to hurt, and threatening to leave. However, the two groups did not differ significantly in terms of QOL, except for the psychological domain being worse in the subjects with anger attacks. Conclusion: Anger attacks are present in half of the patients with obsessive compulsive disorder, and they correlate with the presence of comorbid depression.

    Hypochondriasis and panic disorder are both characterized by prevalent health anxieties and illness beliefs. Therefore, the question as to whether they represent distinct nosological entities has been raised. This study examines how clinical characteristics can be used to differentiate both disorders, taking the possibility of mixed symptomatologies (comorbidity) into account. We compared 46 patients with hypochondriasis, 45 with panic disorder, and 21 with comorbid hypochondriasis plus panic disorder. While panic patients had more comorbidity with agoraphobia, hypochondriasis was more closely associated with somatization. Patients with panic disorder were less pathological than hypochondriacal patients on all subscales of the Whiteley Index (WI) and the Illness Attitude Scales (IAS) except for illness behavior. These differences were independent of somatization. Patients with hypochondriasis plus panic had higher levels of anxiety, more somatization, more general psychopathology and a trend towards increased health care utilization. Clinicians were able to distinguish between patient groups based upon the tendency of hypochondriacal patients to demand unnecessary medical treatments. These results confirm that hypochondriasis and panic disorder are distinguishable clinical conditions, characterized by generally more psychopathology and distress in hypochondriasis.

    The objective of this study was to determine the efficacy of pindolol as an augmentor of fluoxetine in treatment-resistant panic disorder (PD). Twenty-five outpatients having PD with or without agoraphobia were included. These patients had not responded to two different trials with antidepressants and an 8-week trial of fluoxetine 20 mg/day. Treatment-resistant PD was defined as a less than 20% reduction in score on the Panic Self-Questionnaire (number of attacks per week) (PSQ) and the Clinical Anxiety Scale With Panic Attacks (CAS+PA). These patients continued to receive fluoxetine 20 mg/day and were randomly assigned to additionally receive either pindolol (2.5 mg three times daily) or placebo for the following 4 weeks. Evaluations were performed weekly using the Hamilton Rating Scale for Anxiety, the Hamilton Rating Scale for Depression (HAM-D), the CAS+PA, the NIMH Anxiety Scale, the PSQ, and the Clinical Global Impression Scale. The data were analyzed using a repeated-measures analysis of variance (ANOVA) and a t-test for independent samples. Patients treated with the combination of pindolol and fluoxetine (N = 13) demonstrated a significant improvement over the patients treated with fluoxetine and placebo on all rating scales, with the exception of HAM-D. The statistical differences were shown using the repeated-measures ANOVA (baseline, week 2, week 4) and also with t-tests from the second week of the trial. These preliminary results demonstrate that pindolol has an augmenting effect on fluoxetine in patients with treatment-resistant PD.

    Full Text Available Introduction. A cognitive model of aetiology of panic disorder assumes that people who experience frequent panic attacks have tendencies to catastrophically interpret normal and benign somatic sensations - as signs of serious illness. This arise the question: is this cognition specific for patients with panic disorder and in what intensity it is present in patients with serious somatic illness and in healthy subjects. Objective. The aim of the study was to ascertain the differences in the frequency and intensity of 'catastrophic' cognitions related to body sensations, and to ascertain the differences in the frequency and intensity of anxiety caused by different body sensations all related to three groups of subjects: a sample of patients with panic disorder, a sample of patients with history of myocardial infarction and a sample of healthy control subjects from general population. Methods. Three samples are observed in the study: A 53 patients with the diagnosis of panic disorder; B 25 patients with history of myocardial infarction; and C 47 healthy controls from general population. The catastrophic cognitions were assessed by the Agoraphobic Cognitions Questionnaire (ACQ and the Body Sensations Questionnaire (BSQ. These questionnaires assess the catastrophic thoughts associated with panic and agoraphobia (ACQ and the fear of body sensations (BSQ. All study subjects answered questionnaires items, and the scores of the answers were compared among the groups. Results. The results of the study suggest that: 1 There is no statistical difference in the tendency to catastrophically interpret body sensations and therefore to induce anxiety in the samples of healthy general population and patients with history of myocardial infarction; 2 The patients with panic disorder have a statistically significantly more intensive tendency to catastrophically interpret benign somatic symptoms and therefore to induce a high level of anxiety in comparison to the

    This study examines whether, in panic-focused psychodynamic psychotherapy (PFPP), interpretations of conflicts that underlie anxiety (panic-focused or PF-interpretations) are specifically associated with subsequent panic disorder (PD) symptom improvement, over and above the provision of non-symptom-focused interpretations. Technique use in Sessions 2 and 10 of a 24-session PFPP protocol was assessed for the 65 patients with complete outcome data randomized to PFPP in a two-site trial of psychotherapies for PD. Sessions were rated in 15-min segments for therapists' use of PF-interpretations, non-PF-interpretations, and PF-clarifications. Robust regressions were conducted to examine the relationship between these interventions and symptom change subsequent to the sampled session. Interpersonal problems were examined as a moderator of the relationship of PF-interpretations to symptom change. At Session 10, but not at Session 2, patients who received a higher degree of PF-interpretations experienced greater subsequent improvement in panic symptoms. Non-PF-interpretations were not predictive. Patients with more interpersonal distress benefitted particularly from the use of PF-interpretations at Session 10. By the middle phase of PFPP, panic-focused interpretations may drive subsequent improvements in panic symptoms, especially among patients with higher interpersonal distress. Interpretations of conflict absent a panic focus may not be especially helpful.

    Discussion: Early maladaptive schemas and inadaptive ways of behaviors that has been developed by patients to handle these schemas may underly the axis I disorder symptoms such as anxiety, depression, drug abuse and psychosomatic disorders. As we look have a look at our patient, it can be said that her seperation with parents before elementary school may have led to her schemas of desertion and distrust and also teacher being over guarding at the levels of harming sovereignty to compensate the absence of the parents forms the basis of schemas of dependence / incompatence, being harmed and weakness against ilnesses. These schemas may be the reason of the patient's inability to handle certain life problems that may be triggering her panic attack symptoms. Schema therapy led to awareness of the patient about her schemas. Patient who had been thought of more functional ways coping instead of inadaptive ways was free of her panic attack symptoms which were resistant to medical treatment. The schema therapy proceess that has been going on with our patient is a good example for schema therapy that was originally developed for treatment for axis II disorders may also be effective for axis 1 disorders.

  7. Is panic disorder a disorder of physical fitness? A heuristic proposal

    Science.gov (United States)

    Perna, Giampaolo; Caldirola, Daniela

    2018-01-01

    Currently, panic disorder (PD) is considered a mental disorder based on the assumptions that panic attacks (PAs) are “false alarms” that arise from abnormally sensitive defense systems in the central nervous system and that PD is treated with therapies specifically acting on anxiety or fear mechanisms. This article aims to propose an alternative perspective based on the results of some experimental studies. Our heuristic proposal suggests not only that PD may be a mental disorder but also that patients with PD have real abnormal body functioning, mainly involving cardiorespiratory and balance systems, leading to a decline in global physical fitness. PAs, as well as physical symptoms or discomfort in some environmental situations, may be “real alarms” signaling that the adaptability resources of an organism are insufficient to respond appropriately to some internal or external changes, thus representing the transient conscious awareness of an imbalance in body functioning. The antipanic properties of several modern treatments for PD may include their beneficial effects on body functions. Although anxiety or fear mechanisms are evidently involved in PD, we hypothesize that a reduction of physical fitness is the “primum movens” of PD, while anxiety or fear is induced and sustained by repeated signals of impaired body functioning. We propose considering panic in a broader perspective that offers a central role to the body and to contemplate the possible role of somatic treatments in PD. PMID:29623195

    Panic disorder refers to the frequent and recurring acute attacks of anxiety. Objective: This study describes the routine use of mobiles phones (MPs) and investigates the appearance of possible emotional alterations or symptoms related to their use in patients with panic disorder (PD). Background: We compared patients with PD and agoraphobia being treated at the Panic and Respiration Laboratory of The Institute of Psychiatry, Federal University of Rio de Janeiro, Brazil, to a control group of healthy volunteers. Methods: An MP-use questionnaire was administered to a consecutive sample of 50 patients and 70 controls. Results: People with PD showed significant increases in anxiety, tachycardia, respiratory alterations, trembling, perspiration, panic, fear and depression related to the lack of an MP compared to the control group. Conclusions: Both groups exhibited dependence on and were comforted by having an MP; however, people with PD and agoraphobia showed significantly more emotional alterations as well as intense physical and psychological symptoms when they were apart from or unable to use an MP compared to healthy volunteers.

  9. Recurrent spontaneous attacks of dizziness.

    Lempert, Thomas

    2012-10-01

    This article describes the common causes of recurrent vertigo and dizziness that can be diagnosed largely on the basis of history. Ninety percent of spontaneous recurrent vertigo and dizziness can be explained by six disorders: (1) Ménière disease is characterized by vertigo attacks, lasting 20 minutes to several hours, with concomitant hearing loss, tinnitus, and aural fullness. Aural symptoms become permanent during the course of the disease. (2) Attacks of vestibular migraine may last anywhere from minutes to days. Most patients have a previous history of migraine headaches, and many experience migraine symptoms during the attack. (3) Vertebrobasilar TIAs affect older adults with vascular risk factors. Most attacks last less than 1 hour and are accompanied by other symptoms from the posterior circulation territory. (4) Vestibular paroxysmia is caused by vascular compression of the eighth cranial nerve. It manifests itself with brief attacks of vertigo that recur many times per day, sometimes with concomitant cochlear symptoms. (5) Orthostatic hypotension causes brief episodes of dizziness lasting seconds to a few minutes after standing up and is relieved by sitting or lying down. In older adults, it may be accompanied by supine hypertension. (6) Panic attacks usually last minutes, occur in specific situations, and are accompanied by choking, palpitations, tremor, heat, and anxiety. Less common causes of spontaneous recurrent vertigo and dizziness include perilymph fistula, superior canal dehiscence, autoimmune inner ear disease, otosclerosis, cardiac arrhythmia, and medication side effects. Neurologists need to venture into otolaryngology, internal medicine, and psychiatry to master the differential diagnosis of recurrent dizziness.

    To clarify the relationship between panic disorder and the symptoms of hypochondriasis and somatization, we evaluated these symptoms and diagnoses in patients attending an Anxiety Disorders Clinic. Structured clinical interviews, self-report measures, and symptom diaries were used to assess 21 patients with panic disorder, 23 patients with social phobia, and 22 control subjects with no psychiatric disorders. Ten of the patients with panic disorder (48%) also met DSM-IV criteria for hypochondriasis, whereas only one of the patients with social phobia and none of the healthy control subjects met the criteria for this diagnosis. None of the participants met DSM-IV criteria for somatization disorder, even though both anxiety groups reported high levels of somatic symptoms. The panic disorder group reported higher levels of fear about illness and disease conviction and endorsed more somatic symptoms than did the other groups. A higher proportion of panic disorder patients reported previously diagnosed medical conditions (48%) as compared with patients with social phobia (17%) or healthy control subjects (14%). The panic disorder patients with DSM-IV hypochondriasis obtained higher scores on measures of hypochondriacal concerns, somatization, blood-injury phobia, and general anxiety and distress than did the panic disorder patients without hypochondriasis. The results suggest a strong association between panic disorder and hypochondriasis.

    The aim of this naturalistic follow-up study was to examine the effect of pregnancy as a predicting factor of relapse in patients with panic disorder (PD). Eighty-five female patients with PD (between the ages of 20 and 35 years) were included in this study. They were divided into 2 groups based on whether the onset of PD had been during pregnancy (PD-pregnancy [PD-P]) or whether the onset of PD had been while not pregnant (PD-nonpregnant [PD-NP]). Patients were treated with paroxetine up to 40 mg/day for 12 months, and the full responders were tapered off their medication and were monitored for an additional 6 years. Treatment response was assessed using the Panic Self-Questionnaire (PSQ) with full response being defined as "0" panic attacks. Assessments using the PSQ were made at baseline and every 4 weeks for the first twelve months. During the 6-year drug-free follow-up period, patients were assessed using the PSQ every 3 months. Relapse was defined as the occurrence of a panic attack in any phase of the study. The effect of group membership (PD-P vs. PD-NP) and new pregnancies as risk factors for relapse were explored. Sixty-eight patients completed the 6-year follow-up, and each of the study groups (PD-P and PD-NP) was composed of 34 patients. Twenty-six of 34 (76.6%) patients in the PD-P group had another pregnancy, and 15/26 (57%) in this group experienced a relapse during the subsequent pregnancy. Three of 8 (37%) PD-P patients experienced a relapse without pregnancy. Among the second group (PD-NP), 18/34 (52.9%) became pregnant and 8/18 (44.4%) experienced a relapse at the time of pregnancy, whereas 4/16 (25%) experienced a relapse while not pregnant. Patients who relapsed during pregnancy had a more severe relapse (as defined by the severity of the PSQ score) compared with nonpregnant relapsers. Our naturalistic follow-up study demonstrated that pregnancy might confer an increased risk of relapse in PD. Moreover, when compared with patients who develop

    Full Text Available Panic Disorder and agoraphobia offer considerable diagnostic and management challenges, particularly in general practice. We describe a typical case of panic disorder in a young adult. The recent advances in our understanding of brain functions can be used to explain to a certain extent the biologic basis of panic disorder. A hypothetical model integrating current views on panic disorder and agoraphobia has been proposed. The management principles including the role of cognitive therapy and pharmacotherapy have been discussed.

    To determine the nosological and phenomenological overlap and boundaries between panic disorder and hypochondriasis, we compared the symptoms, disability, comorbidity, and medical care of primary care patients with each diagnosis. Patients with DSM-III-R panic disorder were recruited by screening consecutive primary care clinic attenders and then administering a structured diagnostic interview for panic disorder. Patients also completed self-report questionnaires, and their primary care physicians completed questionnaires about them. They were then compared with patients with DSM-III-R hypochondriasis from the same setting who had been studied previously. One thousand six hundred thirty-four patients were screened; 135 (71.0% of the 190 eligible patients) completed the research battery; 100 met lifetime panic disorder criteria. Twenty-five of these had comorbid hypochondriasis. Those without comorbid hypochondriasis (n = 75) were then compared with patients with hypochondriasis without comorbid panic disorder (n = 51). Patients with panic disorder were less hypochondriacal (P somatized less (P somatization disorder symptoms (P hypochondriasis. While hypochondriasis and panic disorder co-occur to some extent in a primary care population, the overlap is by no means complete. These patients are phenomenologically and functionally differentiable and distinct and are viewed differently by their primary care physicians.

    Full Text Available OBJECTIVE: The authors present a profile of panic disorder based on and generalized from the effects of acute and chronic hyperventilation that are characteristic of the respiratory panic disorder subtype. The review presented attempts to integrate three premises: hyperventilation is a physiological response to hypercapnia; hyperventilation can induce panic attacks; chronic hyperventilation is a protective mechanism against panic attacks. METHOD: A selective review of the literature was made using the Medline database. Reports of the interrelationships among panic disorder, hyperventilation, acidosis, and alkalosis, as well as catecholamine release and sensitivity, were selected. The findings were structured into an integrated model. DISCUSSION: The panic attacks experienced by individuals with panic disorder develop on the basis of metabolic acidosis, which is a compensatory response to chronic hyperventilation. The attacks are triggered by a sudden increase in (pCO2 when the latent (metabolic acidosis manifests as hypercapnic acidosis. The acidotic condition induces catecholamine release. Sympathicotonia cannot arise during the hypercapnic phase, since low pH decreases catecholamine sensitivity. Catecholamines can provoke panic when hyperventilation causes the hypercapnia to switch to hypocapnic alkalosis (overcompensation and catecholamine sensitivity begins to increase. CONCLUSION: Therapeutic approaches should address long-term regulation of the respiratory pattern and elimination of metabolic acidosis.OBJETIVO: Os autores apresentam um modelo de transtorno do pânico que se baseia nos efeitos da hiperventilação aguda e crônica, característicos do subtipo respiratório de transtorno do pânico.

    Attempts to understand the underlying mechanisms of association between psychological factors and panic disorder have been mostly based on psychodynamic description. Evidence of the importance of serotonergic (5-HT) system in panic disorder (PD), however, has substanti ally increased in recent years. The objective of our study was to determine whether there was a specific personality profile of panic disorder patients and how it was related to possible neurobiological mechanisms underlying personality dimensions. Sample consisted of 14 inpatients with ICD-X diagnosis of panic disorder and 34 healthy control subjects. Personality dimensions were assessed by Minnesota Multiphasic Personality Inventory (MMPI-201) and Tridimensional Personality Questionnaire (TPQ). To assess central 5-HT function, platelet monoamine-oxidase (MAO) activity was measured. In panic disorder group, higher scores of histrionic, depressive and hypochondriac subscales and significant increase of harm avoidance (HA) scale as well as low MAO activity were found. Negative correlation was established between MAO activity and psychopathic deviance MMPI scale. The obtained results might indicate a specific personality profile of patients with panic disorder, which is characterized by high neuroticism, fearfulness, inhibition, shyness and apprehensive worry. Low MAO activity and high HA scores possibly indicate underlying hyperserotonergic state. The observed correlation between personality traits and MAO activity provide additional support for the hypothesized functional relationship between underlying central monoaminergic activity and temperament traits associated with anxiety, depression and impulsivity.

    This paper studies the relationship between atrial fibrillation and panic disorder. There are often doubts on the differential diagnosis in emergency services and general medical settings. Panic disorder prevalence rates have been found to be high in patients suffering from atrial fibrillation. Various studies have observed that patients diagnosed with anxiety disorders frequently have higher cardiovascular disease rates compared to the general population. Usually, patients suffering from panic disorder exhibit somatic complaints suggesting coronary disease, such as chest pain or palpitations. The aim is to make the correct diagnosis and treatment for these different illnesses, and to decrease the costs due to misdiagnosis.

    Panic attacks (PAs), the core feature of panic disorder, represent a common phenomenon in the general adult population and are associated with a considerable decrease in quality of life and high health care costs. To date, the underlying pathophysiology of PAs is not well understood. A unique feature of PAs is that they represent a rare example of a psychopathological phenomenon that can be reliably modeled in the laboratory in panic disorder patients and healthy volunteers. The most effective techniques to experimentally trigger PAs are those that acutely disturb the acid-base homeostasis in the brain: inhalation of carbon dioxide (CO2), hyperventilation, and lactate infusion. This review particularly focuses on the use of CO2 inhalation in humans and rodents as an experimental model of panic. Besides highlighting the different methodological approaches, the cardio-respiratory and the endocrine responses to CO2 inhalation are summarized. In addition, the relationships between CO2 level, changes in brain pH, the serotonergic system, and adaptive physiological and behavioral responses to CO2 exposure are presented. We aim to present an integrated psychological and neurobiological perspective. Remaining gaps in the literature and future perspectives are discussed. Copyright © 2015 Elsevier Ltd.

    The aim of our study was to evaluate the effectiveness of Cognitive Behavioral Group Therapy (CBGT) in the treatment of Panic Disorder (PD) and to compare the treatment outcome of CBGT versus Paroxetine pharmacotherapy. Fifty seven patients referred to our anxiety disorder clinic for the treatment of PD were randomly allocated to receive either CBGT or Paroxetine. Follow up was done by a masked rater after four and twelve weeks of treatment in order to compare the efficacy of CBGT versus Paroxetine. CBGT and Paroxetine were both effective in the short-term treatment of PD. Assessments at weeks four and twelve of treatment showed no statistically significant differences between the two groups in terms of treatment outcome. Treatment with CBGT alone for the acute phase of PD appears to be equally efficacious to treatment with Paroxetine alone. Our study shows that CBGT produced beneficial results, for it was associated with a reduction in the number and frequency of panic attacks and with an improved feeling of well-being.

    Full Text Available Attempts to understand the underlying mechanisms of association between psychological factors and panic disorder have been mostly based on psychodynamic description. Evidence of the importance of serotonergic (5-HT system in panic disorder (PD, however, has substanti ally increased in recent years. OBJECTIVE The objective of our study was to determine whether there was a specific personality profile of panic disorder patients and how it was related to possible neurobiological mechanisms underlying personality dimensions. PATIENTS AND METHODS Sample consisted of 14 inpatients with ICD-X diagnosis of panic disorder and 34 healthy control subjects. Personality dimensions were assessed by Minnesota Multiphasic Personality Inventory (MMPI-201 and Tridimensional Personality Questionnaire (TPQ. To assess central 5-HT function, platelet monoamine-oxidase (MAO activity was measured. RESULTS In panic disorder group, higher scores of histrionic, depressive and hypochondriac subscales and significant increase of harm avoidance (HA scale as well as low MAO activity were found. Negative correlation was established between MAO activity and psychopathic deviance MMPI scale. CONCLUSION The obtained results might indicate a specific personality profile of patients with panic disorder, which is characterized by high neuroticism, fearfulness, inhibition, shyness and apprehensive worry. Low MAO activity and high HA scores possibly indicate underlying hyperserotonergic state. The observed correlation between personality traits and MAO activity provide additional support for the hypothesized functional relationship between underlying central monoaminergic activity and temperament traits associated with anxiety, depression and impulsivity.

    Our objective was to assess the prevalence of panic disorder, its influence on quality of life (QoL), and the presence of further anxiety and depressive comorbid disorders in outpatients with chronic heart failure (CHF). In a cross-sectional study, anxiety and depressive disorders were diagnosed according to Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition diagnostic criteria in patients with CHF who were aged > or =18 years and had New York Heart Association (NYHA) Functional Classes I-IV, using the Patient Health Questionnaire. Health-related QoL was evaluated using the Short-Form 36 Health Survey (SF-36). Of the 258 participating patients, 24 (9.3%) fulfilled diagnostic criteria for panic disorder. Seven of these (29.2%) were diagnosed with comorbid anxiety disorders, 11 (47.3%) were diagnosed with comorbid depressive disorder, and 5 (20.8%) were diagnosed with other anxiety disorders and any depressive disorder. Female gender [odds ratio (OR)=3.1; 95% confidence interval (95% CI)=1.2-7.8; P=.02] and a lower level of education (OR=0.3; 95% CI=0.1-0.9; P=.04) were associated with the presence of panic disorder. In patients with panic disorder, QoL was significantly more restricted on all subscales of the SF-36 as compared to those without panic disorder, even when age, gender, and NYHA functional class were controlled for (P=.05 to <.01). Approximately 1 of 10 patients with CHF suffers from panic disorder, many of whom also have additional anxiety or depressive comorbid disorders. Female gender and a low level of education are positively associated with the presence of panic disorder. QoL is severely limited by the presence of panic disorder. Diagnosis of mental disorders and treatment offers for affected patients should be available in patient care.

    Whenever we (such as pedestrians) perceive a high density or imminent danger in a confined space, we tend to be panic, which can lead to severe injuries even in the absence of real dangers. Although it is difficult to measure panics in real conditions, we introduced a simple model to study the collective behaviors in condition of fire with dense smoke. Owing to blocking the sight with dense smoke, pedestrians in this condition have two strategies to escape: random-walking or walking along the wall. When the pedestrians are in moderate panic that mean the two types of behaviors are mixed(random-walking and walking along the wall). Our simulation results show that moderate panic, meaning that two escape strategies are mixed, reduces the escape time. In addition, the results indicate that moderate panic can improve the efficiency of escape, this theory also can be useful in a real escape situation. We hope that our research provides the theoretical understanding of underlying mechanisms of panic escape in the condition of poor sight.

    Full Text Available The constructionist approach to social problems has developed a thesis about mass panics and urban legends as "unconstructed social problems". This thesis, advanced by the American sociologist Joel Best, and his analysis of the urban legend of Halloween sadism, have provided the model for studying three mass panics and two urban legends. The three panics in question are the mass exodus from Kraljevo because of a prophesy that the town would be destroyed in an earthquake, the mass fear of body parts thieves in three villages in Srem, and the panic over the appearance of a cannibal sect in the town of Šabac. The two urban legends involve the rich old emigrant whose acquaintance a child from a poor family made while dialling phone numbers at random, and the thieving postman who set up his own business in Russia with the stolen pension money he had been supposed to deliver.

    No studies of psychotherapies for panic disorder (PD) have examined effects on comorbid personality disorders (PersD), yet half such patients have a PersD. In a randomized trial for PD with and without agoraphobia comparing Cognitive-Behavioral Therapy (CBT) and Panic-Focused Psychodynamic Psychotherapy (PFPP), PersD was assessed pre-to-post treatment with the Structured Clinical Interview for the Diagnosis of Axis-II Disorders (SCID-II). For patients completing therapy (n = 118, 54 with PersD), covariance between panic and SCID-II criteria improvements was analyzed. SCID-II diagnostic remission and recovery were evaluated. Comparative efficacy of PFPP versus CBT for improving PersD was analyzed both for the average patient, and as a function of PersD severity. 37 and 17% of PersD patients experienced diagnostic PersD remission and recovery, respectively. Larger reductions in PersD were related to more panic improvement, with a modest effect size (r = 0.28). Although there was no difference between treatments in their ability to improve PersD for the average patient (d = 0.01), patients meeting more PersD criteria did better in PFPP compared to CBT (P = .007), with PFPP being significantly superior at 11 criteria and above (d = 0.66; 3 more criteria lost). PersD presenting in the context of primary PD rarely resolves during psychotherapies focused on PD, and change in PersD only moderately tracks panic improvements, indicating non-overlap of the constructs. Patients receiving panic-focused psychotherapies may require additional treatment for their PersD. PFPP may be superior at improving severe PersD, but replication of this finding is required. © 2017 Wiley Periodicals, Inc.

    Full Text Available A considerable body of evidence suggests the involvement of serotonin neurotransmission in the pathogenesis of panic disorder. Research on pathways and functions of tryptophan, an essential amino acid converted into serotonin, may advance our understanding of serotonergic actions in panic disorder and related phenomena. The investigative approaches in this field include manipulations of tryptophan availability as well as genetic association and functional brain imaging studies. In this review we examine the principle findings of these studies and propose further research directions.

  11. Agent Based Modeling and Simulation of Pedestrian Crowds In Panic Situations

    2016-11-01

    The increasing occurrence of panic stampedes during mass events has motivated studying the impact of panic on crowd dynamics and the simulation of pedestrian flows in panic situations. The lack of understanding of panic stampedes still causes hundreds of fatalities each year, not to mention the scarce methodical studies of panic behavior capable of envisaging such crowd dynamics. Under those circumstances, there are thousands of fatalities and twice that many of injuries every year caused be crowd stampede worldwide, despite the tremendous efforts of crowd control and massive numbers of safekeeping forces. Pedestrian crowd dynamics are generally predictable in high-density crowds where pedestrians cannot move freely and thus gives rise to self-propelling interactions between pedestrians. Although every pedestrian has personal preferences, the motion dynamics can be modeled as a social force in such crowds. These forces are representations of internal preferences and objectives to perform certain actions or movements. The corresponding forces can be controlled for each individual to represent a different variety of behaviors that can be associated with panic situations such as escaping danger, clustering, and pushing. In this thesis, we use an agent-based model of pedestrian behavior in panic situations to predict the collective human behavior in such crowd dynamics. The proposed simulations suggests a practical way to alleviate fatalities and minimize the evacuation time in panic situations. Moreover, we introduce contagious panic and pushing behavior, resulting in a more realistic crowd dynamics model. The proposed methodology describes the intensity and spread of panic for each individual as a function of distances between pedestrians.

É caracterizado por ataques imotivados de mal-estar psíquico e sintomas somáticos, além de ansiedade antecipatória à crise, com prejuízo funcional ao indivíduo. O objetivo deste relato de caso é descrever a associação entre transtorno do pânico e doença do refluxo gastroesofágico (DRGE. MCL, 25 anos, apresentava crises de pânico frequentes, pouco responsivas ao tratamento durante 6 meses, mesmo com readequação da farmacoterapia. Iniciou-se investigação, sendo fechado o diagnóstico de DRGE, cujo tratamento culminou em remissão das crises de pânico. A dor torácica aguda da DRGE era interpretada como ameaça proximal, ocasionando dúvidas sobre passar mal e hiperventilação, servindo como gatilho da cascata cognitiva do pânico, no mesencéfalo dorsal. A inflamação da mucosa esofágica funciona como ameaça distal, estimulando a amígdala e causando ansiedade antecipatória, mantendo a elevação dos hormônios de estresse. Segundo o modelo de Deakin-Graeff, embora a 5-HT iniba o ataque de pânico e facilite a ansiedade antecipatória, no TP esta última é estimulada por meio do núcleo dorsal da rafe. Portanto, casos que incluem a associação TP e DRGE devem ser mais bem examinados, para que haja diagnóstico e tratamento adequados.Panic disorder (PD is a non phobic anxiety disorder that affects 1,5 to 4% worldwide.

    Full Text Available Abstract Background Panic disorder (PD is a common, severe and persistent mental disorder, associated with a high degree of distress and occupational and social disability. A substantial proportion of the population experiences subthreshold and mild PD and is at risk of developing a chronic PD. A promising intervention, aimed at preventing panic disorder onset and reducing panic symptoms, is the 'Don't Panic' course. It consists of eight sessions of two hours each. The purpose of this study is to evaluate the effectiveness of this early intervention – based on cognitive behavioural principles – on the reduction of panic disorder symptomatology. We predict that the experimental condition show superior clinical and economic outcomes relative to a waitlisted control group. Methods/design A pragmatic, pre-post, two-group, multi-site, randomized controlled trial of the intervention will be conducted with a naturalistic follow-up at six months in the intervention group. The participants are recruited from the general population and are randomized to the intervention or a waitlist control group. The intervention is offered by community mental health centres. Included are people over 18 years of age with subthreshold or mild panic disorder, defined as having symptoms of PD falling below the cut-off of 13 on the Panic Disorder Severity Scale-Self Report (PDSS-SR. Primary outcomes are panic disorder and panic symptoms. Secondary outcomes are symptoms of agoraphobia, anxiety, cognitive aspects of panic disorder, depressive symptoms, mastery, health-related quality of life, and cost-effectiveness. We will examine the following variables as potential mediators: cognitive aspects of panic disorder, symptoms of agoraphobia, anxiety and mastery. Potential moderating variables are: socio-demographic characteristics, panic disorder, agoraphobia, treatment credibility and mastery. Discussion This study was designed to evaluate the (cost effectiveness of an

    The present study examined whether early life maternal separation (MS), a model of childhood separation anxiety, predisposes to panic at adulthood. For this purpose, male pups were submitted to 3-h daily maternal separations along postnatal (PN) days of either the 'stress hyporesponsive period' (SHRP) from PN4 to PN14 (MS11) or throughout lactation from PN2 to PN21 (MS20). Pups were further reunited to conscious (CM) or anesthetized (AM) mothers to assess the effect of mother-pup interaction upon reunion. Controls were subjected to brief handling (15 s) once a day throughout lactation (BH20). As adults (PN60), rats were tested for the thresholds to evoke panic-like behaviors upon electrical stimulation of dorsal periaqueductal gray matter and exposed to an elevated plus-maze, an open-field, a forced swim and a sucrose preference test. A factor analysis was also performed to gain insight into the meaning of behavioral tests. MS11-CM rather than MS20-CM rats showed enhanced panic responses and reductions in both swimming and sucrose preference. Panic facilitations were less intense in mother-neglected rats. Although MS did not affect anxiety, MS11-AM showed robust reductions of defecation in an open-field. Factor analysis singled out anxiety, hedonia, exploration, coping and gut activity. Although sucrose preference and coping loaded on separate factors, appetite (adult weight) correlated with active coping in both forced swim and open-field (central area exploration). Concluding, whereas 3h-daily maternal separations during SHRP increased rat's susceptibility to experimental panic attacks, separations throughout lactation had no effects on panic and enhanced active coping.

    Objective: Cognitive Behavioral Therapy (CBT) is an effective intervention for patients with panic disorder (PD). From a theoretical perspective, Eye Movement Desensitization and Reprocessing (EMDR) therapy could also be useful in the treatment of PD because: (1) panic attacks can be experienced as life threatening; (2) panic memories specific to PD resemble traumatic memories as seen in posttraumatic stress disorder (PTSD); and (3) PD often develops following a distressing life event. The primary objective of this Randomized Controlled Trial (RCT), was to compare EMDR therapy with CBT for PD and determine whether EMDR is not worse than CBT in reducing panic symptoms and improving Quality Of Life (QOL). Methods: Two-arm (CBT and EMDR) parallel RCT in patients with PD (N = 84). Patients were measured at baseline (T1), directly after the last therapy session (T2), and 3 months after ending therapy (T3). Non-inferiority testing (linear mixed model with intention-to-treat analysis) was applied. Patients were randomly assigned to 13 weekly 60-min sessions of CBT (N = 42) or EMDR therapy (N = 42). Standard protocols were used. The primary outcome measure was severity of PD at T3, as measured with the Agoraphobic Cognitions Questionnaire (ACQ), the Body Sensations Questionnaire (BSQ), and the Mobility Inventory (MI). The secondary outcome measure was QOL, as measured with the World Health Organization Quality of Life short version (WHOQOL-Bref), at T3. Results: The severity of PD variables ACQ and BSQ showed non-inferiority of EMDR to CBT, while MI was inconclusive (adjusted analyses). Overall QOL and general health, Psychological health, Social relationships, and Environment showed non-inferiority of EMDR to CBT, while Physical health was inconclusive. Conclusion: EMDR therapy proved to be as effective as CBT for treating PD patients.

    Full Text Available Some studies have reported the importance of electroencephalography (EEG as a method for investigating abnormal parameters in psychiatric disorders. Different findings in time and frequency domain analysis with regard to central nervous system arousal during acute panic states have already been obtained. This study aimed to systematically review the EEG findings in panic disorder (PD, discuss them having a currently accepted neuroanatomical hypothesis for this pathology as a basis, and identify limitations in the selected studies. Literature search was conducted in the databases PubMed and ISI Web of Knowledge, using the keywords electroencephalography and panic disorder; 16 articles were selected. Despite the inconsistency of EEG findings in PD, the major conclusions about the absolute power of alpha and beta bands point to a decreased alpha power, while beta power tends to increase. Different asymmetry patterns were found between studies. Coherence studies pointed to a lower degree of inter-hemispheric functional connectivity at the frontal region and intra-hemispheric at the bilateral temporal region. Studies on possible related events showed changes in memory processing in PD patients when exposed to aversive stimuli. It was noticed that most findings reflect the current neurobiological hypothesis of PD, where inhibitory deficits of the prefrontal cortex related to the modulation of amygdala activity, and the subsequent activation of subcortical regions, may be responsible to trigger anxiety responses. We approached some important issues that need to be considered in further researches, especially the use of different methods for analyzing EEG signals. Keywords: Electroencephalography, panic disorder, neurobiology, brain mapping.

    Directory of Open Access Journals (Sweden)

    Anna Gibbs

    2011-04-01

    Full Text Available This essay describes the phenomenon of panic from both neurological and affective points of view. It draws on the work of Japp Panksepp, who argues for the importance of distinguishing between fear as a response to physical threat, and panic as a response to the loss of the attachment object. While fear flees, panic, perhaps contrary to appearances, seeks security. This view of panic throws a new light on classic analyses of crowd behaviour, among them those of Le Bon, Tarde and Canetti, but it also has implications for how panic takes hold via electronic media, and for how outbreaks may be calmed. Finally, the essay argues that mediatised panic is a distraction from fear—in which anything at all may represent physical danger, but which at least offers a range of possible responses for addressing the problem, and offers the opportunity for the transformative work performed by cognition on affect. Here the paper draws on the script theory of Silvan Tomkins to provoke questions of the social usefulness of fear in the face of some current arguments to the contrary.

    Researchers have been using the electroencephalogram to better understand the cognitive and neurobiological bases of panic disorder (PD) through the P300 component; this is an electric potential of the cerebral cortex that is generated in response to external sensorial stimuli and which involves more complex neurophysiological processes related to stimulus interpretation; it is then used to investigate possible alterations in the information processing and attention of patients suffering from this disorder. Aiming to verify the results found by experimental articles already published about P300 in PD patients and the information processing differences between PD patients and healthy controls, a systematic review of the PubMed and Institute for Scientific Information databases was conducted. The selection criterion involved those articles, written in English, which referred to an experimental research that focused on the P300 component, with a sample composed of PD (or panic attacks) patients. Seven articles were found that fit the selected criteria. Most of the articles show that these patients suffer from: impaired information processing and attention, an inability to automatically respond to new stimuli, and impaired interpretation of internal and external stimuli related to the disorder. Such impairment may be related to an unspecified dysfunction in the limbic-reticular structures, which would affect: active, focused and short-term attention, working and short-term memory, recognition and decision making. Some limitations were highlighted, such as the use of small samples and possible comorbidity with other disorders, which did not allow clearer results. This research can contribute to understand the neurobiological differences of PD patients and develop treatments based on such evidence.

    The escape response to electrical or chemical stimulation of the dorsal periaqueductal gray matter (DPAG) has been associated with panic attacks. In order to explore the validity of the DPAG stimulation model for the study of panic disorder, we determined if the aversive consequences of the electrical or chemical stimulation of this midbrain area can be detected subsequently in the elevated T-maze. This animal model, derived from the elevated plus-maze, permits the measurement in the same rat of a generalized anxiety- and a panic-related defensive response, i.e., inhibitory avoidance and escape, respectively. Facilitation of inhibitory avoidance, suggesting an anxiogenic effect, was detected in male Wistar rats (200-220 g) tested in the elevated T-maze 30 min after DPAG electrical stimulation (current generated by a sine-wave stimulator, frequency at 60 Hz) or after local microinjection of the GABA A receptor antagonist bicuculline (5 pmol). Previous electrical (5, 15, 30 min, or 24 h before testing) or chemical stimulation of this midbrain area did not affect escape performance in the elevated T-maze or locomotion in an open-field. No change in the two behavioral tasks measured by the elevated T-maze was observed after repetitive (3 trials) electrical stimulation of the DPAG. The results indicate that activation of the DPAG caused a short-lived, but selective, increase in defensive behaviors associated with generalized anxiety

    The escape response to electrical or chemical stimulation of the dorsal periaqueductal gray matter (DPAG) has been associated with panic attacks. In order to explore the validity of the DPAG stimulation model for the study of panic disorder, we determined if the aversive consequences of the electrical or chemical stimulation of this midbrain area can be detected subsequently in the elevated T-maze. This animal model, derived from the elevated plus-maze, permits the measurement in the same rat of a generalized anxiety- and a panic-related defensive response, i.e., inhibitory avoidance and escape, respectively. Facilitation of inhibitory avoidance, suggesting an anxiogenic effect, was detected in male Wistar rats (200-220 g) tested in the elevated T-maze 30 min after DPAG electrical stimulation (current generated by a sine-wave stimulator, frequency at 60 Hz) or after local microinjection of the GABA{sub A} receptor antagonist bicuculline (5 pmol). Previous electrical (5, 15, 30 min, or 24 h before testing) or chemical stimulation of this midbrain area did not affect escape performance in the elevated T-maze or locomotion in an open-field. No change in the two behavioral tasks measured by the elevated T-maze was observed after repetitive (3 trials) electrical stimulation of the DPAG. The results indicate that activation of the DPAG caused a short-lived, but selective, increase in defensive behaviors associated with generalized anxiety.

    Although comorbid panic disorder is associated with more severe symptoms and poorer therapeutic response in depressive patients, the relationship between panic disorder and risk of suicide attempt has not been confirmed. This study aimed to examine the relationship between comorbid panic disorder and clinical characteristics associated with suicidal risk as well as the likelihood of suicide attempt. A total of 223 outpatients with current major depressive disorder participated in the study. Both subjects with panic disorder (33%) and those without panic disorder (67%) were compared based on history of suicide attempts, current psychopathologies, and traits of impulsivity and anger. Subjects with panic disorder had higher levels of impulsivity, depression, and hopelessness and were more likely to report a history of suicide attempts. Subjects with panic disorder were younger at the time of first suicide attempt than those without panic disorder. Logistic regression analyses indicated that comorbid panic disorder was significantly associated with a history of suicide attempts after adjusting for other clinical correlates (odds ratio = 2.8; p depressive disorder may be associated with a more severe burden of illness and may independently increase the likelihood of suicide attempt.

    Regional glucose metabolic rates were measured in patients with panic disorder during the performance of auditory discrimination. Those regions examined by Reiman and colleagues in their blood flow study of panic disorder were examined with a higher resolution positron emission tomography (PET) scanner and with the tracer (F-18)-2-fluoro-2-deoxyglucose (FDG). In contrast to the blood flow findings of Reiman et al., we did not find global gray metabolic differences between patients with panic disorder and normal controls. Consistent with the findings of Reiman et al., we found hippocampal region asymmetry. We also found metabolic decreases in the left inferior parietal lobule and in the anterior cingulate (trend), as well as an increase in the metabolic rate of the medial orbital frontal cortex (trend) of panic disorder patients. It is unclear whether the continuous performance task (CPT) enhanced or diminished findings that would have been noted in a study performed without task.

    Full Text Available Objective: Cognitive Behavioral Therapy (CBT is an effective intervention for patients with panic disorder (PD. From a theoretical perspective, Eye Movement Desensitization and Reprocessing (EMDR therapy could also be useful in the treatment of PD because: (1 panic attacks can be experienced as life threatening; (2 panic memories specific to PD resemble traumatic memories as seen in posttraumatic stress disorder (PTSD; and (3 PD often develops following a distressing life event. The primary objective of this Randomized Controlled Trial (RCT, was to compare EMDR therapy with CBT for PD and determine whether EMDR is not worse than CBT in reducing panic symptoms and improving Quality Of Life (QOL.Methods: Two-arm (CBT and EMDR parallel RCT in patients with PD (N = 84. Patients were measured at baseline (T1, directly after the last therapy session (T2, and 3 months after ending therapy (T3. Non-inferiority testing (linear mixed model with intention-to-treat analysis was applied. Patients were randomly assigned to 13 weekly 60-min sessions of CBT (N = 42 or EMDR therapy (N = 42. Standard protocols were used. The primary outcome measure was severity of PD at T3, as measured with the Agoraphobic Cognitions Questionnaire (ACQ, the Body Sensations Questionnaire (BSQ, and the Mobility Inventory (MI. The secondary outcome measure was QOL, as measured with the World Health Organization Quality of Life short version (WHOQOL-Bref, at T3.Results: The severity of PD variables ACQ and BSQ showed non-inferiority of EMDR to CBT, while MI was inconclusive (adjusted analyses. Overall QOL and general health, Psychological health, Social relationships, and Environment showed non-inferiority of EMDR to CBT, while Physical health was inconclusive.Conclusion: EMDR therapy proved to be as effective as CBT for treating PD patients.Trial Registration: Dutch Trial Register, Nr. 3134 http://www.trialregister.nl/trialreg/admin/rctview.asp?TC=3134

    Quality of life encompasses domains of personal happiness, role fulfillment, and health status. Increasing attention has been paid to the relationship between quality of life and panic disorder, with accumulating evidence now available to suggest impairment in several domains among subjects with panic disorder. This review summarizes the results of community-based and treatment-seeking populations of subjects with panic disorder. Impaired personal happiness, restricted role functioning, and increased use of health services are all described. Evidence suggests that accurate diagnosis and effective treatment can significantly lessen health service utilization, resulting in substantial cost offset and also leading to increased work productivity and personal effectiveness.

    Full Text Available The use of illegal drugs has often been shown to ignite fear and insecurity in society. When a new drug appears the media typically reports on this drug and the risk it poses. Soon after ecstasy appeared in Iceland in the 1990s its use created a major public uproar and insecurity in Icelandic society. In the article the theory of moral panic will be used to examine if the arrival of ecstasy to Iceland ignited a moral panic. Media reports on ecstasy, public reactions, interest groups and government institutions will be analysed. Discourse analysis is employed on newspaper reporting on ecstasy between 1985 and 1997 to detect signs of moral panic. The main conclusion is that evidence suggests that a moral panic existed in Iceland as described in well-known theories on the subject.

    March 11, 2011, a huge earthquake and tidal waves in Japan lead to dangerous levels of nuclear leakage at Fukushima nuclear plant, the nuclear accident also cause public panic m many countries. To investigate the reason of the public panic, we employ the theories of sociology and psychology, analyzed that the public panic come from Ignorant Panic. Herd Behavior, Primacy Effect, Stereotype Activation Effect, and the superposition of these effects. In addition, we proposed three measures to the public panic: First, we should emphasize the safety of nuclear power and establish the positive image of nuclear power Second, we should emphasize the popular science of nuclear power so that nu clear power can be accepted in the public; Third, we should enhance the psychological intervention system for nuclear safe emergency and improve the effect of psychological intervention

    Full Text Available Objective: Health anxiety is the fear of being or getting seriously sick due to the misinterpretation of physical symptoms. Severe health anxiety is also named as hypochondriasis. Belief of having a disease due to the misinterpretation of physical symptoms is also seen in panic disorder and somatization disorder. The aim of this study is to search the health anxiety in panic disorder, somatization disorder and hypochondriasis and compare it with healthy volunteers. Method: SCID-I was used to determine psychiatric disorders in patient group. In order to assess the clinical state and disease severity of the patient group; Panic and Agoraphobia Scale, Hamilton Anxiety Rating Scale, Inventory of Depressive Symptomatology were used for patients with panic disorder and Symptom Interpretation Questionnaire, Hamilton Anxiety Rating Scale, Inventory of Depressive Symptomatology were used for patients with somatization disorder and hypochondriasis. Brief Symptom Inventory was used to assess psychopathology in healthy group. In order to evaluate health anxiety of both groups, Health Anxiety Inventory-Short Form was used. Results: Results of this study support that health anxiety is a significant major component of hypochondriasis. On the other hand, health anxiety seems to be common in panic disorder and somatization disorder. Health anxiety also may be a part of depression or present in healthy people. Conclusion: Further studies are needed in order to search how to manage health anxiety appropriately and which psychotherapeutic interventions are more effective.

    onset and maintenance of tic attacks. These cases provide support for the view that tic attacks are triggered and maintained by psychological factors, thereby challenging the view that tic attacks merely reflect extended bouts of tics. As such, we propose that the movements seen in tic attacks may resemble a combination of tics and functional neurological movements, with tic attacks reflecting episodes of panic and anxiety for individuals with TS.

    Patients with Panic Disorder (PD) direct their attention towards potential threat, followed by panic attacks, and increased sweat production. Onés own anxiety sweat odor influences the attentional focus, and discrimination of threat or non-threat. Since olfactory projection areas overlap with neuronal areas of a panic-specific fear network, the present study investigated the neuronal processing of odors in general and of stress-related sweat odors in particular in patients with PD. A sample of 13 patients with PD with/ without agoraphobia and 13 age- and gender-matched healthy controls underwent an fMRI investigation during olfactory stimulation with their stress-related sweat odors (TSST, ergometry) as well as artificial odors (peach, artificial sweat) as non-fearful non-body odors. The two groups did not differ with respect to their olfactory identification ability. Independent of the kind of odor, the patients with PD showed activations in fronto-cortical areas in contrast to the healthy controls who showed activations in olfaction-related areas such as the amygdalae and the hippocampus. For artificial odors, the patients with PD showed a decreased neuronal activation of the thalamus, the posterior cingulate cortex and the anterior cingulate cortex. Under the presentation of sweat odor caused by ergometric exercise, the patients with PD showed an increased activation in the superior temporal gyrus, the supramarginal gyrus, and the cingulate cortex which was positively correlated with the severity of the psychopathology. For the sweat odor from the anxiety condition, the patients with PD showed an increased activation in the gyrus frontalis inferior, which was positively correlated with the severity of the psychopathology. The results suggest altered neuronal processing of olfactory stimuli in PD. Both artificial odors and stress-related body odors activate specific parts of a fear-network which is associated with an increased severity of the psychopathology.

    Gay panic refers to a heterosexual man violently responding to unwanted sexual advances from a gay man. In court, the defendant may argue he was provoked or temporarily insane. This study utilized 352 jury-eligible citizens to assess differences across mediums of gay panic. Participants were asked to read vignettes depicting a control, gay panic as provocation, or gay panic as insanity condition and provide verdicts and ratings of blame and responsibility. Participants also completed measures assessing political orientation and homonegativity. Data were analyzed via a MANCOVA, a chi-square goodness-of-fit test, and general linear modeling. Verdicts, victim blame, and ratings of responsibility differed across vignette conditions, with an observed leniency effect when gay panic was claimed in either context. Homonegativity also exacerbated patterns of prodefendant views, as participants higher in homonegativity assigned higher victim blame, lower defendant responsibility, and more lenient verdicts in the gay panic conditions. The effect of political orientation was nuanced, as only republicans in the provocation condition followed the anticipated pattern in rendering more lenient verdicts. Results provide additional support for the notion gay panic defenses may be, in part, fueled by political beliefs and prejudicial beliefs against persons of sexual minority status. Drawing from a justification-suppression model, it may be that in cases of gay panic, a context is created in which prejudiced ideologies can be openly expressed via leniency on the defendant. Implications may be relevant to future criminal law policies and practices, particularly advocacy and policy efforts, judicial training, and trial consultation to attorneys for juror selection and development of trial strategy.

  2. SIRS Model of Passengers’ Panic Propagation under Self-Organization Circumstance in the Subway Emergency

    2014-01-01

    Full Text Available Subway emergency may lead to passengers’ panic, especially under self-organizing circumstance, which will spread rapidly and have an adverse impact on the society. This paper builds an improved SIRS model of passengers’ panic spread in subway emergency with consideration of passengers’ density, the characteristic of subway car with the confined space, and passengers’ psychological factors. The spread of passengers’ panic is simulated by use of Matlab, which draws the rules of how group panic spreads dynamically. The trend of stable point of the infection ratio is analyzed by changing different parameters, which help to draw a conclusion that immunization rate, spontaneous immune loss rate, and passenger number have a great influence on the final infected ratio. Finally, we propose an integrated control strategy and find the peak of passengers’ panic and the final infected ratio is greatly improved through the numerical simulation. The research plays a vital role in helping the government and subway administration to master the panic spread mechanism and reduce the panic spread by improving measures and also provides certain reference significance for rail system construction, emergency contingency plans, and the construction and implementation of emergency response system.

    Reported neuroimaging studies have shown functional and morphological changes of temporal lobe structures in panic patients, but only one used a volumetric method. The aim of the present study was to determine the volume of temporal lobe structures in patients with panic disorder, measured by magnetic resonance imaging. Eleven panic patients and eleven controls matched for age, sex, handedness, socioeconomic status and years of education participated in the study. The mean volume of the left temporal lobe of panic patients was 9% smaller than that of controls (t{sub 21} = 2.37, P = 0.028). In addition, there was a trend (P values between 0.05 and 0.10) to smaller volumes of the right temporal lobe (7%, t{sub 21} = 1.99, P = 0.06), right amygdala (8%, t{sub 21} = 1.83, P = 0.08), left amygdala (5%, t{sub 21} = 1.78, P 0.09) and left hippocampus (9%, t{sub 21} = 1.93, P = 0.07) in panic patients compared to controls. There was a positive correlation between left hippocampal volume and duration of panic disorder (r = 0.67, P = 0.025), with recent cases showing more reduction than older cases. The present results show that panic patients have a decreased volume of the left temporal lobe and indicate the presence of volumetric abnormalities of temporal lobe structures. (author)

    Little is known about the mental health impact of terrorism beyond posttraumatic stress disorder (PTSD) and depression. The associations between exposure to the September 11, 2001 (9/11) attacks in New York City and generalized anxiety disorder (GAD) symptoms were examined in a sample of 929 primary care patients. After controlling for PTSD, depression, panic and substance use disorders, and pre-9/11 trauma, patients who screened positive (vs. negative) for GAD symptoms were roughly twice as likely to report having a loved one at the 9/11 disaster site, twice as likely to know someone who was killed by the attacks, and twice as likely to know someone who was involved with the rescue/recovery efforts after the disaster. Implications for treatment and future research are discussed.

    Full Text Available Objective: To conduct a review of the literature on the possible neuropsychological deficits present in patients with panic disorder. Methods: We performed a systematic review and search of the PubMed, ISI and PsycInfo scientific databases, with no time limits, using the following key words: cognitive, function, panic, and disorder. Of the 971 articles found, 25 were selected and 17 were included in this review. The inclusion criterion was at least one neuropsychological assessment task in patients with panic disorder. Results: The number of publications has grown gradually, especially those assessing executive functions, corresponding to the neurobiological model most widely accepted. Of all the functions evaluated, these patients had lower performance in memory tasks and higher performance in affective processing tasks related to the disorder. However, these data require further investigation due to the high rate of comorbidities, the small sample sizes of the included studies and little standardization of instruments used. Conclusion: The results showed a greater occurrence of deficits in memory and enhanced affective processing related to panic disorder.

    The aim of this study is to evaluate the association between childhood trauma and the quality of parental bonding in panic disorder compared to non-clinical controls. 123 patients and 123 paired controls were evaluated with the Mini International Neuropsychiatric Interview, the Childhood Trauma Questionnaire and the Parental Bonding Instrument. The Parental Bonding Instrument and the Childhood Trauma Questionnaire were highly correlated. Panic disorder patients presented higher rates of emotional abuse (OR = 2.54, p = 0.001), mother overprotection (OR = 1.98, p = 0.024) and father overprotection (OR = 1.84, p = 0.041) as compared to controls. Among men with panic disorder, only mother overprotection remained independently associated with panic disorder (OR = 3.28, p = 0.032). On the other hand, higher father overprotection (OR = 2.2, p = 0.017) and less father warmth (OR = 0.48, p = 0.039) were independently associated with panic disorder among female patients. Higher rates of different types of trauma, especially emotional abuse, are described in panic disorder patients as compared to controls. The differences regarding gender and parental bonding could be explained in the light of the psychodynamic theory.

    Full Text Available Abstract Background Internet based self-help for panic disorder (PD has proven to be effective. However, studies so far have focussed on treating a full-blown disorder. Panic symptoms that do not meet DSM-IV criteria are more prevalent than the full-blown disorder and patients with sub-clinical panic symptoms are at risk of developing PD. This study is a randomised controlled trial aimed to evaluate an Internet based self-help intervention for sub-clinical and mild PD compared to a waiting list control group. Methods Participants with mild or sub-clinical PD (N = 128 will be recruited in the general population. Severity of panic and anxiety symptoms are the primary outcome measures. Secondary outcomes include depressive symptoms, quality of life, loss of production and health care consumption. Assessments will take place on the Internet at baseline and three months after baseline. Discussion Results will indicate the effectiveness of Internet based self-help for sub-clinical and mild PD. Strengths of this design are the external validity and the fact that it is almost completely conducted online.

    The aim of this study was to survey the available literature on psychological development of panic disorder with or without agoraphobia [PD(A)] and its relationship with the neurobiology and the treatment of panic. Both a computerized (PubMed) and a manual search of the literature were performed. Only English papers published in peer-reviewed journals and referring to PD(A) as defined by the diagnostic classifications of the American Psychiatric Association or of the World Health Organization were included. A staging model of panic exists and is applicable in clinical practice. In a substantial proportion of patients with PD(A), a prodromal phase and, despite successful treatment, residual symptoms can be identified. Both prodromes and residual symptoms allow the monitoring of disorder evolution during recovery via the rollback phenomenon. The different stages of the disorder, as well as the steps of the rollback, have a correspondence in the neurobiology and in the treatment of panic. However, the treatment implications of the longitudinal model of PD(A) are not endorsed, and adequate interventions of enduring effects are missing.

    Many patients with panic disorder meet criteria for at least one other diagnosis, most commonly other anxiety or mood disorders. Cognitive-behavioral therapy is the best empirically supported psychotherapy for panic disorder. There is now evidence indicating that cognitive-behavioral therapy for panic disorder yields positive benefits upon comorbid disorders. The present study aimed to examine the predictors of broad dimensions of psychopathology in panic disorder after cognitive-behavioral therapy. Two hundred patients affected by panic disorder were treated with manualized group cognitive-behavioral therapy. We examined if the baseline personality dimensions of NEO Five Factor Index predicted the subscales of Symptom Checklist-90 Revised at endpoint using multiple regression analysis based on the intention-to-treat principle. Conscientiousness score of NEO Five Factor Index at baseline was a predictor of four Symptom Checklist-90 Revised subscales including obsessive-compulsive ( β = -0.15, P cognitive-behavioral therapy. For the purpose of improving a wide range of psychiatric symptoms with patients affected by panic disorder, it may be useful to pay more attention to this personal trait at baseline.

    Deficits in facial emotion processing is a major characteristic of patients with panic disorder. It is known that visual stimuli with different spatial frequencies take distinct neural pathways. This study investigated facial emotion processing involving stimuli presented at broad, high, and low spatial frequencies in patients with panic disorder. Eighteen patients with panic disorder and 19 healthy controls were recruited. Seven event-related potential (ERP) components: (P100, N170, early posterior negativity (EPN); vertex positive potential (VPP), N250, P300; and late positive potential (LPP)) were evaluated while the participants looked at fearful and neutral facial stimuli presented at three spatial frequencies. When a fearful face was presented, panic disorder patients showed a significantly increased P100 amplitude in response to low spatial frequency compared to high spatial frequency; whereas healthy controls demonstrated significant broad spatial frequency dependent processing in P100 amplitude. Vertex positive potential amplitude was significantly increased in high and broad spatial frequency, compared to low spatial frequency in panic disorder. Early posterior negativity amplitude was significantly different between HSF and BSF, and between LSF and BSF processing in both groups, regardless of facial expression. The possibly confounding effects of medication could not be controlled. During early visual processing, patients with panic disorder prefer global to detailed information. However, in later processing, panic disorder patients overuse detailed information for the perception of facial expressions. These findings suggest that unique spatial frequency-dependent facial processing could shed light on the neural pathology associated with panic disorder. Copyright © 2016 Elsevier B.V.

    After the events of September 11, 2001 terrorist working has become an important factor in the forecasts to adopt in the face of the possibility of confronting different radiological emergencies. The not wanted events of exposure to ionizing radiations can take place by flaws of systems or accidents, or also by criminal voluntary actions. These malevolent actions can include attacks or sabotages in nuclear plants, detonation of manufactured nuclear devices or acquired under ground, robbery of radioactive sources to manufacture the calls dirty bombs or to cause damage, panic or threats. In the scenarios in that the radiological emergency is voluntarily provoked the moment and place of the attack are chosen by the aggressors, therefore the ionizing radiations will be in not prepared atmospheres neither equipped to the effect. This increases the confusion, the panic and the damage not only caused by the radiation effects but also by the uncertainty and consequent reactions. To diminish the effects of this type of threats it is necessary to make forecasts and to train the personnel that it can be direct or indirectly involved. During 2005, an exercise in which it was outlined the robbery by part of a group command of a source of Co 60 of 5000 Ci that it was transported to make a decanting in a medical center of The Pampa county, Argentina.

    Full Text Available Objective: To compare prey and snake paradigms performed in complex environments to the elevated plus-maze (EPM and T-maze (ETM tests for the study of panic attack- and anticipatory anxiety-like behaviors in rodents. Methods: PubMed was reviewed in search of articles focusing on the plus maze test, EPM, and ETM, as well as on defensive behaviors displayed by threatened rodents. In addition, the authors’ research with polygonal arenas and complex labyrinth (designed by the first author for confrontation between snakes and small rodents was examined. Results: The EPM and ETM tests evoke anxiety/fear-related defensive responses that are pharmacologically validated, whereas the confrontation between rodents and snakes in polygonal arenas with or without shelters or in the complex labyrinth offers ethological conditions for studying more complex defensive behaviors and the effects of anxiolytic and panicolytic drugs. Prey vs. predator paradigms also allow discrimination between non-oriented and oriented escape behavior. Conclusions: Both EPM and ETM simple labyrinths are excellent apparatuses for the study of anxiety- and instinctive fear-related responses, respectively. The confrontation between rodents and snakes in polygonal arenas, however, offers a more ethological environment for addressing both unconditioned and conditioned fear-induced behaviors and the effects of anxiolytic and panicolytic drugs.

    Cognitive–behavioral therapy (CBT) and pharmacotherapy are similarly effective for treating panic disorder with mild or no agoraphobia, but little is known about the mechanism through which these treatments work. The present study examined some of the criteria for cognitive mediation of treatment change in CBT alone, imipramine alone, CBT plus imipramine, and CBT plus placebo. Ninety-one individuals who received 1 of these interventions were assessed before and after acute treatment, and after a 6-month maintenance period. Multilevel moderated mediation analyses provided preliminary support for the notion that changes in panic-related cognitions mediate changes in panic severity only in treatments that include CBT.

    Panic disorder (PD) patients are constantly concerned about future panic attacks and exhibit general hypersensitivity to unpredictable threat. We aimed to reveal phasic and sustained brain responses and functional connectivity of the amygdala and the bed nucleus of the stria terminalis (BNST) during threat anticipation in PD. Using functional magnetic resonance imaging (fMRI), we investigated 17 PD patients and 19 healthy controls (HC) during anticipation of temporally unpredictable aversive and neutral sounds. We used a phasic and sustained analysis model to disentangle temporally dissociable brain activations. PD patients compared with HC showed phasic amygdala and sustained BNST responses during anticipation of aversive v. neutral stimuli. Furthermore, increased phasic activation was observed in anterior cingulate cortex (ACC), insula and prefrontal cortex (PFC). Insula and PFC also showed sustained activation. Functional connectivity analyses revealed partly distinct phasic and sustained networks. We demonstrate a role for the BNST during unpredictable threat anticipation in PD and provide first evidence for dissociation between phasic amygdala and sustained BNST activation and their functional connectivity. In line with a hypersensitivity to uncertainty in PD, our results suggest time-dependent involvement of brain regions related to fear and anxiety.

    The authors examined the specificity and course of psychiatric disorders from early childhood through adolescence in offspring of parents with confirmed panic disorder and major depressive disorder. The authors examined rates of psychiatric disorders at 10-year-follow-up (mean age, 14 years) in four groups: offspring of referred parents with panic and depression (N=137), offspring of referred parents with panic without depression (N=26), offspring of referred parents with depression without panic (N=48), and offspring of nonreferred parents with neither disorder (N=80). Follow-up assessments relied on structured interviews with the adolescents and their mothers; diagnoses were rated present if endorsed by either. Parental panic disorder, independently of parental depression, predicted lifetime rates in offspring of multiple anxiety disorders, panic disorder, agoraphobia, social phobia, and obsessive-compulsive disorder. Parental depression independently predicted offspring bipolar, drug use, and disruptive behavior disorders. Parental panic and depression interacted to predict specific phobia and major depressive disorder. Phobias were elevated in all at-risk groups, and depression was elevated in both offspring groups of parents with depression (with or without panic disorder), with the highest rates in the offspring of parents with depression only. Parental depression independently predicted new onset of depression, parental panic disorder independently predicted new onset of social phobia, and the two interacted to predict new onset of specific phobia and generalized anxiety disorder. At-risk offspring continue to develop new disorders as they progress through adolescence. These results support the need to screen and monitor the offspring of adults presenting for treatment of panic disorder or major depressive disorder.

    Research evidence points to the existence of racial-ethnic disparities in both access to and quality of mental health services for African Americans with panic disorder. Current panic disorder evaluation and treatment paradigms are not responsive to the needs of many African Americans. The primary individual, social, and health-care system factors that limit African Americans' access to care and response to treatment are not well understood. Low-income African American women with panic disorder participated in a series of focus-group sessions designed to elicit (1) their perspectives regarding access and treatment barriers and (2) their recommendations for designing a culturally consistent panic treatment program. Fear of confiding to others about panic symptoms, fear of social stigma, and lack of information about panic disorder were major individual barriers. Within their social networks, stigmatizing attitudes toward mental illness and the mentally ill, discouragement about the use of psychiatric medication, and perceptions that symptoms were the result of personal or spiritual weakness had all interfered with the participants' treatment seeking efforts and contributed to a common experience of severe social isolation. None of the focus-group members had developed fully effective therapeutic relationships with either medical or mental health providers. They described an unmet need for more interactive and culturally authentic relationships with treatment providers. Although the focus-group sessions were not intended to be therapeutic, the women reported that participation in the meetings had been an emotionally powerful and beneficial experience. They expressed a strong preference for the utilization of female-only, panic disorder peer-support groups as an initial step in the treatment/recovery process. Peer-support groups for low-income African American women with panic disorder could address many of the identified access and treatment barriers.

    ógicas identificáveis e relevantes, com implicações diagnósticas e terapêuticas.Introduction/Objectives: Hypochondriasis has been associated with several anxiety disorders, especially with panic disorder (PD. It is estimated that 50% to 70% of PD patients have hypochondriacal symptoms and 13% to 17% of patients with hypochondriasis have associated PD. The objective of this study was to review the literature on clinical, phenomenological, cognitive and psychodynamic relationships between PD and hypochondriasis, and to discuss conceptual aspects and diagnostic criteria. Methods: A Medline search was conducted between 1990 and 2001 using the following keywords: panic disorder, agoraphobia, hypochondriasis, and hypochondriacal concerns. Results: It is considered hypochondriasis comorbidity in PD only when health worries are not restricted to panic attack symptoms. Although usually regarded as a secondary phenomenon, hypochondriacal preoccupations precede the first panic attack in many PD patients and may be considered prodromal symptoms. In a vicious circle, anxiety may lead to excessive health worries, selective self-observation and anticipation of the worst outcomes. Though a catastrophic bias is common to both diseases, in PD the autonomic symptoms increase rapidly culminating in a panic attack, and the dread catastrophe seems to be imminent, leading to avoidant behaviors and immediate quest for help. Hypochondriasis is characterized by a fear of more insidious diseases, hypervigilance, search for reassurance behaviors, more dysfunctional beliefs, poorer doctor-patient relationship, and a wider range of feelings misinterpreted as catastrophic. Pathological fear of death and alexithymia may play an important role in both disorders. Conclusions: The clinical overlapping of PD/agoraphobia and hypochondriasis is significant but not complete. The relationship between the two disorders is complex and possibly bidirectional, both increasing their mutual vulnerability. There are

    Full Text Available Abstract Background Interoceptive exposure has been validated as an effective component of cognitive behavioral therapy (CBT for the treatment of panic disorder but has hitherto received little research attention. We examined the effectiveness of various interoceptive exposure exercises using the Body Sensations Questionnaire (BSQ (Chambless et al., 1984. Methods We first performed an exploratory principal factor analysis of all the items contained in the BSQ to obtain meaningful dimensions of interoceptive fears. Next, we examined the correlations between each interoceptive exposure task's degree of similarity to panic attacks and each BSQ factor and then examined whether the BSQ factor scores decreased in comparison with the baseline values when the corresponding exposure tasks were successfully completed by the subjects. Results The factor analyses revealed four factors, which we named "pseudoneurological fears", "gastrointestinal fears", "cardiorespiratory fears" and "fears of dissociative feelings." Among the nine interoceptive exposure tasks, 'hyperventilation', 'shaking head', 'holding breath' and 'chest breathing' were considered to reproduce pseudoneurological symptoms, 'breathing through a straw' was considered to reproduce gastrointestinal symptoms, and 'spinning' was considered to reproduce both pseudoneurological and dissociative symptoms; none of the interoceptive exercises were found to reproduce cardiorespiratory symptoms. Among each group of patients for whom 'hyperventilation', 'holding breath', 'spinning' or 'chest breathing' was effective, a significant improvement in the BSQ pseudoneurological fears factor scores was observed. On the other hand, no significant difference between the baseline and endpoint values of the BSQ gastrointestinal fears or the BSQ fears of dissociative feelings factor scores were observed among the patients for whom 'spinning' or 'breathing through a straw' was effective.

    Full Text Available Carlo MarchesiPsychiatric Section, Department of Neuroscience, University of Parma, Parma, ItalyAbstract: Panic disorder (PD is a disabling condition which appears in late adolescence or early adulthood and affects more frequently women than men. PD is frequently characterized by recurrences and sometimes by a chronic course and, therefore, most patients require longterm treatments to achieve remission, to prevent relapse and to reduce the risks associated with comorbidity. Pharmacotherapy is one of the most effective treatments of PD. In this paper, the pharmacological management of PD is reviewed. Many questions about this effective treatment need to be answered by the clinician and discussed with the patients to improve her/his collaboration to the treatment plan: which is the drug of choice; when does the drug become active; which is the effective dose; how to manage the side effects; how to manage nonresponse; and how long does the treatment last. Moreover, the clinical use of medication in women during pregnancy and breastfeeding or in children and adolescents was reviewed and its risk-benefit balance discussed.Keywords: panic disorder, pharmacological treatment, treatment guidelines

    The current study investigates sudden gains (rapid symptom reduction) in group cognitive-behavioral therapy for panic disorder. Sudden gains occurring after session 2 of treatment predicted overall symptom reduction at treatment termination and some changes in cognitive biases. Meanwhile, sudden gains occurring immediately following session 1 were not associated with symptom reduction or cognitive change. Together, this research points to the importance of examining sudden gains across the entire span of treatment, as well as the potential role of sudden gains in recovery from panic disorder.

It is often associated with agoraphobia. The present article reviews the current status of pharmacotherapy for PD with or without agoraphobia as well as the current status of treatments combing pharmacotherapy with cognitive behavior therapy (CBT. The review has been written with a focus on randomized controlled trials, meta-analyses, and reviews that have been published over the past few years. Effective pharmacological treatments include tricyclic antidepressants, monoamine oxidase inhibitors, selective serotonin reuptake inhibitors, serotonin norepinephrine reuptake inhibitors, and various benzodiazepines. Treatment results obtained with CBT compare well with pharmacotherapy, with evidence that CBT is at least as effective as pharmacotherapy. Combining pharmacotherapy with CBT has been found to be superior to antidepressant pharmacotherapy or CBT alone, but only in the acute-phase treatment. Long term studies on treatments combining pharmacotherapy and CBT for PD with or without agoraphobia have found little benefit, however, for combination therapies versus monotherapies. New investigations explore the potential additional value of sequential versus concomitant treatments, of cognitive enhancers and virtual reality exposure therapy, and of education, self management and Internet-based interventions.Keywords: Panic disorder, agoraphobia, pharmacotherapy, cognitive-behavioral therapy, combination treatments.

Die resultate van hierdie studie dui daarop dat 'n toename in doelwitmoeilikheidsgraad nie altyd tot ‘n ooreenstemmende toename in prestasie lei nie. Hierdie resultaat kon ook nie op grond van 'n gebrek aan doelwitaanvaarding verklaar word nie. Daar is voorts gevind dat die wyse waarop 'n nie-spesifieke doelwit gestel word, 'n beduidende invloed op prestasie kan hê. Finansiële aansporings blyk ook 'n onafhanklike invloed op prestasie te hê. Bepaalde aspekte van Locke se teorie word dus deur bogenoemde resultate bevraagteken. Aanbevelings vir verdere navorsing word ten slotte gedoen.

    Full Text Available This study was designed for evaluation of epiphyseal plate histological changes of femur bones in osteopetrotic op/op mice.In this study 5 osteopetrotic op/op mice which were purchased from the commercial source were used.The animals were killed by overdose of chloroform and their femur bones were extracted. The bones were fixed in 10% formaldehyde and decalcified by HCl (0.6N, and routine histological processing were performed. The sections were stained by H&E methods and studied by conventional light microscopy. The results showed that, proliferative zone (PZ and especially hypertrophic zone (HZ were much thickened. In the ossification zone, trabecular bones were irregular and atypical osteoblast cells were observed. The osteoclast cells were not attached to trabecular bones. The bone marrow cavity was restricted and bone marrow cells were poor and scattered. Findings of the present investigation are similar to those reported about epiphyseal plate in osteosclerotic (OC mice in which epiphyseal plate especially hypertrophic zone was thickened and chondrocytes were not substituted for osteoblasts in calcified cartilage area. Also, osteoclast cells had been inactive or absent in OC mice. For prevention of other complication due to the epiphyseal plate changes in new borne, suitable and punctually treatment protocols such as prescription of Macrophage Colony Stimulating-Factor (MCS-F could be useful.

This kind of policy has been widely advocated, most notably by Bagehot (1873). To analyze such a policy, I build a model with three key features: 1) bank panics can occur in equilibrium, 2) there can be moral hazard, 3) the central bank can create money which is willingly held.

    Full Text Available This paper proposes a framework for evaluating the DevOps maturity in organizations. The methodology was based on a literature review from which a theory was developed that sought to relate the main DevOps practices. For each of them, some research constructs were defined, which are precisely the objects to be measured by this model. Through a structure based on questions with graded answers, it is possible to indicate how much the unit of analysis that is being evaluated adheres to a DevOps approach in the development and implementation of applications. Therefore, the main contribution of this work is the DevOps maturity evaluation framework that can be easily replicated and, because of that, may be used by several companies to map possible improvement points in their implementation of the DevOps perspective for software development.

    The purposes of this study are to investigate the prevalence of major depressive disorder, panic disorder, and post-traumatic stress disorder (PTSD) in Korean subway drivers, and find the association between these disorders and the drivers' person-under-train (PUT) experiences. A total of 826 subway drivers who participated in a cross-sectional work and health survey were included for this study. The Korean version of the Composite International Diagnostic Interview 2.1 was applied to assess major depressive disorder, panic disorder, and PTSD. The date of PUT, whether victim died, and how many PUTs the drivers experienced were asked using a structured questionnaire. The standardized prevalence ratios (SPRs) for lifetime prevalence of panic disorder and PTSD in subway drivers were 13.3 (95 % confidence interval [CI] 6.6-22.4) and 2.1 (95 % CI 1.1-3.4), respectively. In lifetime prevalence, after adjusting for age, education, income, and working career, the drivers who experienced PUT had significantly higher risks for panic disorder (odds ratio [OR] = 4.2, 95 % CI 1.2-16.6) and PTSD (OR = 4.4, 95 % CI 1.3-16.4). In 1-year prevalence, the drivers who experienced PUT had a significantly higher risk for PTSD (OR = 11.7, 95 % CI 1.9-225.8). There was no significant value of SPR and OR in major depressive disorder. This study suggests that Korean subway drivers are at higher risk for panic disorder and PTSD compared to the general population, and PUT experience is associated with panic disorder and PTSD. Drivers who have experienced PUT should be treated quickly, sympathetically, and sensitively by a psychological professional and their colleagues, so they can return to work soon.

    We performed simple segregation analyses of panic disorder using 126 families of probands with DSM-III-R panic disorder who were ascertained for a family study of anxiety disorders at an anxiety disorders research clinic. We present parameter estimates for dominant, recessive, and arbitrary single major locus models without sex effects, as well as for a nongenetic transmission model, and compare these models to each other and to models obtained by other investigators. We rejected the nongenetic transmission model when comparing it to the recessive model. Consistent with some previous reports, we find comparable support for dominant and recessive models, and in both cases estimate nonzero phenocopy rates. The effect of restricting the analysis to families of probands without any lifetime history of comorbid major depression (MDD) was also examined. No notable differences in parameter estimates were found in that subsample, although the power of that analysis was low. Consistency between the findings in our sample and in another independently collected sample suggests the possibility of pooling such samples in the future in order to achieve the necessary power for more complex analyses. 32 refs., 4 tabs.

    Panic disorder (PD) is a very common anxiety disorder and is often a chronic disabling condition. However, little is known about the factors that predict health-related quality of life (HRQOL) other than sociodemographic factors and illness-related symptomatology that explain HRQOL in only small to modest degrees. This study explored whether anxiety-related individual traits including anxiety sensitivity and trait anxiety can predict independently HRQOL in panic patients. Patients with panic disorder with or without agoraphobia (N=230) who met the diagnostic criteria in the Structured Clinical Interview for DSM-IV were recruited. Stepwise regression analysis was performed to determine the factors that predict HRQOL in panic disorder. HRQOL was assessed by the 36-item Short-Form Health Survey (SF-36). Anxiety sensitivity was an independent predictor of bodily pain and social functioning whereas trait anxiety independently predicted all of the eight domains of the SF-36. Our data suggests that the assessment of symptomatology as well as individual anxiety-related trait should be included in the evaluation of HRQOL in panic patients.

    Full Text Available The hypothalamus is a forebrain structure critically involved in the organization of defensive responses to aversive stimuli. Gamma-aminobutyric acid (GABAergic dysfunction in dorsomedial and posterior hypothalamic nuclei is implicated in the origin of panic-like defensive behavior, as well as in pain modulation. The present study was conducted to test the difference between these two hypothalamic nuclei regarding defensive and antinociceptive mechanisms. Thus, the GABA A antagonist bicuculline (40 ng/0.2 µL or saline (0.9% NaCl was microinjected into the dorsomedial or posterior hypothalamus in independent groups. Innate fear-induced responses characterized by defensive attention, defensive immobility and elaborate escape behavior were evoked by hypothalamic blockade of GABA A receptors. Fear-induced defensive behavior organized by the posterior hypothalamus was more intense than that organized by dorsomedial hypothalamic nuclei. Escape behavior elicited by GABA A receptor blockade in both the dorsomedial and posterior hypothalamus was followed by an increase in nociceptive threshold. Interestingly, there was no difference in the intensity or in the duration of fear-induced antinociception shown by each hypothalamic division presently investigated. The present study showed that GABAergic dysfunction in nuclei of both the dorsomedial and posterior hypothalamus elicit panic attack-like defensive responses followed by fear-induced antinociception, although the innate fear-induced behavior originates differently in the posterior hypothalamus in comparison to the activity of medial hypothalamic subdivisions.

  1. Panic and comorbid depression and their associations with stress reactivity, interoceptive awareness and interoceptive accuracy of various bioparameters.

    Science.gov (United States)

    Limmer, Jan; Kornhuber, Johannes; Martin, Alexandra

    2015-10-01

    While current theories on perception of interoceptive signals suggest impaired interoceptive processing in psychiatric disorders such as panic disorder or depression, heart-rate (HR) interoceptive accuracy (IAc) of panic patients under resting conditions is superior to that of healthy controls. Thus, in this study, we chose to assess further physiological parameters and comorbid depression in order to get information on how these potentially conflicting findings are linked together. We used a quasi-experimental laboratory design which included multi-parametric physiological data collection of 40 panic subjects and 53 matched no-panic controls, as well as experimental induction of stress and relaxation over a time-course. Stress reactivity, interoceptive awareness (IAw; from the Body Perception Questionnaire (BPQ)) and IAc (as correlation between self-estimation and physiological data) were major outcome variables. Self-estimation of bioparametrical change was measured via numeric rating scales. Panic subjects had stronger HR-reaction and more accurate HR-interoception. Concurrently, though, their IAc of skin conductance level, pulse amplitude and breathing amplitude was significantly lower than that of the control group. Interestingly, comorbid depression was found to be associated with increased IAw but attenuated IAc. Demand characteristics and a categorical approach to panic confine the results. The potentially conflicting findings coalesce, as panic was associated with an increase of the ability to perceive the fear-related parameter and a simultaneous decrease of the ability to perceive other parameters. The superordinate integration of afferent signals might be impaired. Copyright © 2015 The Authors. Published by Elsevier B.V. All rights reserved.

    Full Text Available This article aims to describe important points in the history of panic disorder concept, as well as to highlight the importance of its diagnosis for clinical and research developments. Panic disorder has been described in several literary reports and folklore. One of the oldest examples lies in Greek mythology - the god Pan, responsible for the term panic. The first half of the 19th century witnessed the culmination of medical approach. During the second half of the 19th century came the psychological approach of anxiety. The 20th century associated panic disorder to hereditary, organic and psychological factors, dividing anxiety into simple and phobic anxious states. Therapeutic development was also observed in psychopharmacological and psychotherapeutic fields. Official classifications began to include panic disorder as a category since the third edition of the American Classification Manual (1980. Some biological theories dealing with etiology were widely discussed during the last decades of the 20th century. They were based on laboratory studies of physiological, cognitive and biochemical tests, as the false suffocation alarm theory and the fear network. Such theories were important in creating new diagnostic paradigms to modern psychiatry. That suggests the need to consider a wide range of historical variables to understand how particular features for panic disorder diagnosis have been developed and how treatment has emerged.O objetivo deste artigo é descrever alguns pontos importantes na história do desenvolvimento do conceito de transtorno de pânico e ressaltar a importância do diagnóstico para o progresso da pesquisa e da clínica.

    Full Text Available In this paper, the authors aim to present the concept of DevOps (Development & Operations, considering its degree of novelty in the area of project management. Firstly, the authors will bring theoretical arguments to support the idea that DevOps is an early-stage methodology, built on the Agile principles, but coming with its own contributions in project management for software development and implementation. Therefore, we believe that after a short time, DevOps will replace its predecessors. Secondly, we experienced this methodology by developing a small project in academic environment by three teams of master students, using VersionOne software. The Conclusions will emphasize the relevance and the future expected effects of DevOps methodology in the project management domain.

    It has been hypothesized that parents of patients with obsessive compulsive disorder exhibit specific traits. 320 consecutive inpatient admissions who met criteria for OCD, depression, and panic disorder checked a list of adjectives to describe their parents. Patients with OCD were 1) less likely to perceive their mothers as disorganized than depressives, 2) more likely to perceive their mothers as overprotective than depressives and 3) less likely to perceive their fathers as demanding than patients with panic.

Gangguan Panik merupakan serangan panik yang berulang-ulang dengan onset cepat dan durasi sangat singkat. Karena adanya keluhan fisik berat pada waktu serangan, pasien menjadi ketakutan mereka akan mendapat serangan jantung, stroke dan lain-lain. Kadang pasien berfikir mereka akan kehilangan kontrol atau menjadi gila. Lama-lama pasien akan menghindari tempat-tempat atau situasi serangan paniknya pernah terjadi terutama tempat kegiatan sosial atau tempat yang susah untuk menyelamatkan diri, hal ini dianggap sebagai penyebab terjadinya Agorafobia. Gangguan Panik bisa disebabkan faktor biologik,genetik atau psikososial. Penatalaksanaan sebaiknya kombinasi Psikofarmaka dan Psikoterapi.

    Although several neuroanatomical models of panic disorder have been proposed, little is known regarding the neurological mechanisms underlying cognitive-behavioral therapy (CBT) in patients with panic disorder. This study was performed to identify the brain structures that show changes of regional cerebral blood flow (rCBF) after CBT in patients with panic disorder. Seven patients who were diagnosed as panic disorder by DSM-IV were treated with CBT for 8 weeks and twelve healthy volunteers joined in this study. Serial 99m Tc-ECD brain perfusion SPECT images were aquisited and PDSS-SR (Self-Report version of Panic Disorder Severity Scale) and ACQ (Agoraphobic Cognitive Question) scores were measured just before and after CBT in all patients. Data were analyzed using SPM2. Subjective symptoms were improved, and PDSS-SR and ACQ scores were significantly reduced (14.9 ± 3.9 vs. 7.0 ± 1.8, ρ < 0.05; 30.3 ± 8.5 vs. 21.6 ± 3.4, ρ < 0.05, respectively) after CBT in panic patients. Before CBT, a significant increase of rCBF was found in the cingulate gylus, thalamus, midbrain, both medial frontal and temporal lobes of the panic patients compared to the normal volunteers. After CBT, we observed a significant rCBF decrease in the left parahippocamus, right insula and cingulate gyrus, both frontal and temporal lobes, and a significant rCBF increase in both the occipital lobes, left insula, both frontal and left parietal lobes. These data suggested that CBT is effective for panic disorder and diminish the activity of the brain areas associated with fear in panic disorder

    2011-04-01

    Full Text Available This article critically examines moral panic as a political strategy in maintaining the hegemony of the nuclear family, the sanctity of hetereosexual relationships and the heteronormative social order. It focuses on the moral panic associated with children and sexuality, particularly that which is manifested around non-heterosexual subjectivities. The discussion is based on media representations of the moral panic associated with the Play School saga, The Tillman Child Care Centre / Learn to Include booklets and the We’re Here resource. It explores the hegemonic discourses around childhood innocence, sexuality and the construction of the homosexual as ‘folk devil’ and shows how these discourses are mobilised by conservative politicians and moral entrepreneurs to strategically instigate a moral panic at critical points in time.

    Background The neuropeptides orexin A and B play a role in reward and feeding and are critical for arousal. However, it was not initially appreciated that most prepro-orexin synthesizing neurons are almost exclusively concentrated in the perifornical hypothalamus, which when stimulated elicits panic-associated behavior and cardiovascular responses in rodents and self-reported “panic attacks” and “fear of dying” in humans. More recent studies support a role for the orexin system in coordinating an integrative stress response. For instance, orexin neurons are highly reactive to anxiogenic stimuli, are hyperactive in anxiety pathology, and have strong projections to anxiety and panic-associated circuitry. Although the two cognate orexin receptors are colocalized in many brain regions, the orexin 2 receptor (OX2R) most robustly maps to the histaminergic wake-promoting region, while the orexin 1 receptor (OX1R) distribution is more exclusive and dense in anxiety and panic circuitry regions, such as the locus ceruleus. Overall, this suggests that OX1Rs play a critical role in mobilizing anxiety and panic responses. Methods Here, we used a CO2-panic provocation model to screen a dual OX1/2R antagonist (DORA-12) to globally inhibit orexin activity, then a highly selective OX1R antagonist (SORA1, Compound 56) or OX2R antagonist (SORA2, JnJ10397049) to assess OX1R and OX2R involvement. Results All compounds except the SORA2 attenuated CO2-induced anxiety-like behaviors, and all but the SORA2 and DORA attenuated CO2-induced cardiovascular responses. Conclusions SORA1s may represent a novel method of treating anxiety disorders, with no apparent sedative effects that were present with a benzodiazepine. PMID:26332431

    1998-10-28

    Cognitive therapists suggest panic disorder to result from 'catastrophic' misinterpretation of bodily sensations. The patient suffering from panic disorder consistently misinterprets normal anxiety responses, such as racing heart, breathlessness or dizziness, as indicating impending disaster. Cognitive therapists, who challenge the traditional view of anxiety as 'free-floating' and irrational, argue that the patient's anxiety is an understandable response to their misinterpretations, and advocate a treatment method based on the patient's specific cognitive make-up and on the principle of collaborative empiricism. The patient is gently guided to identify and challenge idiosyncratic cognitions, and to consider alternative interpretations of danger signs. The article provides an outline of the treatment method and its empirical support.

    Drug-free symptomatic panic patients, drug-treated nonsymptomatic patients and healthy controls were submitted to simulated public speaking. Subjective anxiety, cognitive impairment and discomfort measured by the visual analog mood scale as well as skin conductance level were higher in symptomatic patients than in controls at the beginning of the experimental session, nonsymptomatic patients lying in between. Subjective sedation, spontaneous fluctuations of skin conductance, heart rate and blood pressure were similar in the three groups. Preparation and performance of speech decreased sedation while increasing anxiety, cognitive impairment, level and fluctuations of skin conductance, heart rate and blood pressure. Anxiety, cognitive impairment and conductance level were less increased in symptomatic patients than in controls. Electrodermal activity, but not cardiovascular measures of sympathetic arousal correlated with anticipatory anxiety. Chronic treatment with serotonin uptake inhibitors attenuated the differences between panic patients and controls, supporting the participation of serotonin in panic disorder.

    CO(2) respiration stimulates both anxiety and dyspnea ("air hunger") and has long been used to study panic vulnerability and respiratory control. High comorbidity with panic attacks suggests individuals with bipolar disorder may also mount a heightened anxiety response to CO(2). Moreover, problems in the arousal and modulation of appetites are central to the clinical syndromes of mania and depression; hence CO(2) may arouse an abnormal respiratory response to "air hunger". 72 individuals (34 bipolar I, 25 depressive and bipolar spectrum, 13 with no major affective diagnosis) breathed air and air with 5% CO(2) via facemask for up to 15 min each; subjective and respiratory responses were recorded. Nearly half the subjects diverged from the typical response to a fixed, mildly hypercapneic environment, which is to increase breathing acutely, and then maintain a hyperpneic plateau. The best predictors of an abnormal pattern were bipolar diagnosis and anxiety from air alone. 25 individuals had a panic response; panic responses from CO(2) were more likely in subjects with bipolar I compared to other subjects, however the best predictors of a panic response overall were anxiety from air alone and prior history of panic attacks. Heterogeneous sample, liberal definition of panic attack. Carbon dioxide produces abnormal respiratory and heightened anxiety responses among individuals with bipolar and depressive disorders. These may be due to deficits in emotional conditioning related to fear and appetite. Although preliminary, this work suggests a potentially useful test of a specific functional deficit in bipolar disorder.

    Full Text Available PURPOSE: To investigate the impact of alcohol intoxication and withdrawal on the course of social phobia and panic disorder. METHOD: A group of 41 alcoholic inpatients undergoing detoxification therapy were interviewed using the SCID-I (DSM-IV and questions to detect fluctuations in the course of social phobia and panic disorder as a function of the different phases in alcohol dependence (intoxication, withdrawal, and lucid interval. RESULTS: Only 1 (2.4% patient presented panic disorder throughout life, and 9 (21.9% had panic attacks during alcohol intoxication or during the withdrawal syndrome. Sixteen (39% alcoholic patients showed social phobia with onset prior to drug use. However, drinking eventually became unable to alleviate social phobia symptoms or worsened such symptoms in 31.2% of social-phobic patients. While patients with social phobia reported a significant improvement in psychiatric symptoms during alcohol intoxication, patients experiencing panic attacks worsened significantly during intoxication. In the withdrawal phase, patients with social phobia tended to have more and more intense phobic symptoms. CONCLUSION: Our findings indicate that the impact of alcohol intoxication is different for social phobia as compared to panic disorder, at first decreasing the social-phobic symptoms but later aggravating them. In panic disorder, the impact of intoxication by alcohol is more harmful, at least in the short term.OBJETIVO: Estudar o impacto das fases de intoxicação e de abstinência do uso de álcool sobre o curso da fobia social e do transtorno de pânico.

The findings remain inconsistent. Cortisol awakening response (CAR is a noninvasive biomarker of stress system activity. We designed the study to assess CAR in drug-naïve PD patients.   Materials and methods: We assessed CAR in 14 psychotropic drug-naïve outpatients with PD and 14 healthy controls. The severity of PD was assessed with Panic and Agoraphobia Scale. The severity of anxiety and depression was screened with Hospital Anxiety and Depression Scale.   Results: No significant difference in CAR between PD patients and control group was found. No correlations were observed between CAR and anxiety severity measures in PD patients and controls.   Limitations: The number of participating subjects was relatively small, and the study results apply to nonsuicidal drug-naïve PD patients without agoraphobia and with short-illness duration. There was a lack of control on subjects’ compliance with the sampling instructions.  Conclusion: The study provides no support for elevated CAR levels in drug-naïve PD patients without agoraphobia.

    Previous animal studies have suggested that hepatocyte growth factor (HGF) could be associated with depression- and anxiety-related behaviors. Our aim was to relate serum HGF levels with State-Trait Anxiety Inventory (STAI), Profile of Mood State (POMS), and Revised NEO Personality Inventory (NEO-PI-R) scores in patients with panic disorder (with or without agoraphobia) and healthy controls. We examined 67 patients with panic disorders and 97 controls. Patients were split into two groups according to whether they exhibited a 50% improvement in test scores (good/high response group: n = 26) or not (poor/low response group: n = 41). In both healthy control and panic disorder individuals, there were no significant associations between HGF serum levels and STAI or NEO-PI-R scores. However, there was a significant correlation between serum HGF levels and fatigue in healthy control subjects in as scored by POMS testing. HGF concentration in the good/high response group was significantly elevated compared to both the low/poor response group (p disorders. 2010. Published by Elsevier Ltd. All rights reserved.

    To review current evidence for the clinical and cost-effectiveness of self-management interventions for panic disorder, phobias and obsessive-compulsive disorder (OCD). Papers were identified through computerized searches of databases for the years between 1995 and 2003, manual searches and personal contacts. Only randomized-controlled trials were reviewed. Ten studies were identified (one OCD, five panic disorder, four phobias). Effective self-management interventions included cognitive-behavioural therapy (CBT) and exposure to the trigger stimuli for phobias and panic disorders. All involved homework. There was evidence of effectiveness in terms of improved symptoms and psychological wellbeing when compared with standard care, waiting list or relaxation. Brief interventions and computer-based interventions were effective for most participants. In terms of quality, studies were mainly based on small samples, lacked long-term follow-up, and failed to address cost-effectiveness. Despite the limitations of reviewed studies, there appears to be sufficient evidence to warrant greater exploration of self-management in these disorders. Copyright 2005 Blackwell Munksgaard.

    The use of the hallucinogenic brew ayahuasca, obtained from infusing the shredded stalk of the malpighiaceous plant Banisteriopsis caapi with the leaves of other plants such as Psychotria viridis, is growing in urban centers of Europe, South and North America in the last several decades. Despite this diffusion, little is known about its effects on emotional states. The present study investigated the effects of ayahuasca on psychometric measures of anxiety, panic-like and hopelessness in members of the Santo Daime, an ayahuasca-using religion. Standard questionnaires were used to evaluate state-anxiety (STAI-state), trait-anxiety (STAI-trait), panic-like (ASI-R) and hopelessness (BHS) in participants that ingested ayahuasca for at least 10 consecutive years. The study was done in the Santo Daime church, where the questionnaires were administered 1h after the ingestion of the brew, in a double-blind, placebo-controlled procedure. While under the acute effects of ayahuasca, participants scored lower on the scales for panic and hopelessness related states. Ayahuasca ingestion did not modify state- or trait-anxiety. The results are discussed in terms of the possible use of ayahuasca in alleviating signs of hopelessness and panic-like related symptoms.

  6. Non-disruptive tactics of suppression are superior in countering terrorism, insurgency, and financial panics.

    Science.gov (United States)

    Siegel, David A

    2011-04-13

    Suppressing damaging aggregate behaviors such as insurgency, terrorism, and financial panics are important tasks of the state. Each outcome of these aggregate behaviors is an emergent property of a system in which each individual's action depends on a subset of others' actions, given by each individual's network of interactions. Yet there are few explicit comparisons of strategies for suppression, and none that fully incorporate the interdependence of individual behavior. Here I show that suppression tactics that do not require the removal of individuals from networks of interactions are nearly always more effective than those that do. I find using simulation analysis of a general model of interdependent behavior that the degree to which such less disruptive suppression tactics are superior to more disruptive ones increases in the propensity of individuals to engage in the behavior in question. Thus, hearts-and-minds approaches are generally more effective than force in counterterrorism and counterinsurgency, and partial insurance is usually a better tactic than gag rules in quelling financial panics. Differences between suppression tactics are greater when individual incentives to support terrorist or insurgent groups, or susceptibilities to financial panic, are higher. These conclusions have utility for policy-makers seeking to end bloody conflicts and prevent financial panics. As the model also applies to mass protest, its conclusions provide insight as well into the likely effects of different suppression strategies undertaken by authoritarian regimes seeking to hold on to power in the face of mass movements seeking to end them.

    Full Text Available Routine general practice (GP care is rarely comprehensively described in clinical trials. This paper examines routine GP care within the lifestyle approach to managing panic (LAMP study. The aim of this paper is to describe/discuss routine GP care for panic disorder (PD patients within both study arms in the LAMP study. An unblinded pragmatic randomised controlled trial in 15 East of England GP practices (2 primary care trusts. Participants met Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria for PD with/without agoraphobia. Follow-up measures recorded at 20 weeks/10 months following randomisation. Control arm, unrestricted routine GP care (practice appointments, referrals and prescriptions. Trial arm, occupational therapyled lifestyle treatment comprising lifestyle review of fluid intake, diet pattern, exercise, caffeine, alcohol and nicotine. Primary outcome measure: beck anxiety inventory. At baseline, participants attended 2-3 times more GP appointments than population average, reducing at 10 months to 1.6 times population average for routine GP care and 0.97 population average for lifestyle arm. At 10 months, 33% fewer referrals (6 referrals; 0 mental health than at baseline (9 referrals; 2 mental health were made for lifestyle arm patients compared with 42% increase (from 12 referrals; 8 mental health at baseline to 17 referrals; 7 mental health in GP care arm. Selective serotonin reuptake inhibitors were prescribed most often. Benzodiazepines and beta-blockers were prescribed more often than tricyclic against current clinical guidelines. In conclusion, we found that PD patients at baseline were high healthcare resource users. Treatment in both study arms reduced resource use. Routine GP care requires further review for this patient group.

  8. Mechanisms of change in cognitive behavioral therapy for panic disorder: The unique effects of self-efficacy and anxiety sensitivity

    The present study examined temporal dependencies of change of panic symptoms and two promising mechanisms of change (self-efficacy and anxiety sensitivity) during an 11-session course of cognitive-behavior therapy (CBT) for Panic Disorder (PD). 361 individuals with a principal diagnosis of PD completed measures of self-efficacy, anxiety sensitivity, and PD symptoms at each session during treatment. Effect size analyses indicated that the greatest changes in anxiety sensitivity occurred early in treatment, whereas the greatest changes in self-efficacy occurred later in treatment. Results of parallel process latent growth curve models indicated that changes in self-efficacy and anxiety sensitivity across treatment uniquely predicted changes in PD symptoms. Bivariate and multivariate latent difference score models indicated, as expected, that changes in anxiety sensitivity and self-efficacy temporally preceded changes in panic symptoms, and that intraindividual changes in anxiety sensitivity and self-efficacy independently predicted subsequent intraindividual changes in panic symptoms. These results provide strong evidence that changes in self-efficacy and anxiety sensitivity during CBT influence subsequent changes in panic symptoms, and that self-efficacy and anxiety sensitivity may therefore be two distinct mechanisms of change of CBT for PD that have their greatest impact at different stages of treatment.

    2007-05-01

    Exposure therapy and cognitive behaviour therapy (CBT) are both effective in the treatment of panic disorder with agoraphobia. Cognitive theories suggest that the way in which exposure to avoided situations is implemented in either treatment may be crucial. In particular, it is suggested that clinical improvement will be greatest if opportunities for disconfirmation of feared catastrophes are maximized. In a small pilot study, 16 patients with panic disorder and (moderate or severe) agoraphobia were randomly allocated to either habituation based exposure therapy (HBET) or exposure planned as a belief disconfirmation strategy and accompanied by dropping of safety-seeking behaviours. Both treatments were brief (total of 3.25 h of exposure) and were similar in terms of expectancy of change. Patients in the CBT condition showed significantly greater improvements in self-report measures of anxiety, panic and situational avoidance. They also completed significantly more steps in a standardized behavioural walk, during which they experienced significantly less anxiety. The controlled effect sizes for CBT were substantial (range 1.7-2.7), which suggests it may be a particularly efficient way of managing therapeutic exposure to feared situations in panic disorder with agoraphobia. Further research is needed to clarify the mechanism of change involved.

  13. Disability and Comorbidity: Diagnoses and Symptoms Associated with Disability in a Clinical Population with Panic Disorder

    Directory of Open Access Journals (Sweden)

    Caroline A. Bonham

    2014-01-01

    Full Text Available Background. Anxiety disorders are associated with considerable disability in the domains of (1 work, (2 social, and (3 family and home interactions. Psychiatric comorbidity is also known to be associated with disability. Methods. Data from the Cross-National Collaborative Panic Study was used to identify rates of comorbid diagnoses, anxiety and depression symptom ratings, and Sheehan disability scale ratings from a clinical sample of 1165 adults with panic disorder. Results. Comorbid diagnoses of agoraphobia, major depression, and social phobia were associated with disability across the three domains of work, social, and family and home interactions. The symptom of agoraphobic avoidance makes the largest contribution to disability but there is no single symptom cluster that entirely predicts impairment and disability. Limitations. The findings about the relative contributions that comorbid diagnoses make to disability only apply to a population with panic disorder. Conclusions. Although panic disorder is not generally considered to be among the serious and persistent mental illnesses, when it is comorbid with other diagnoses, it is associated with considerable impairment. In particular, the presence of agoraphobic avoidance should alert the clinician to the likelihood of important functional impairment. When measuring the functional impact of comorbid anxiety disorders, both the categorical and the dimensional approaches to diagnosis make valuable contributions.

    Panic disorder is characterised by the presence of recurrent unexpected panic attacks, discrete periods of fear or anxiety that have a rapid onset and include symptoms such as racing heart, chest pain, sweating and shaking. Panic disorder is common in the general population, with a lifetime prevalence of 1% to 4%. A previous Cochrane meta-analysis suggested that psychological therapy (either alone or combined with pharmacotherapy) can be chosen as a first-line treatment for panic disorder with or without agoraphobia. However, it is not yet clear whether certain psychological therapies can be considered superior to others. In order to answer this question, in this review we performed a network meta-analysis (NMA), in which we compared eight different forms of psychological therapy and three forms of a control condition. To assess the comparative efficacy and acceptability of different psychological therapies and different control conditions for panic disorder, with or without agoraphobia, in adults. We conducted the main searches in the CCDANCTR electronic databases (studies and references registers), all years to 16 March 2015. We conducted complementary searches in PubMed and trials registries. Supplementary searches included reference lists of included studies, citation indexes, personal communication to the authors of all included studies and grey literature searches in OpenSIGLE. We applied no restrictions on date, language or publication status. We included all relevant randomised controlled trials (RCTs) focusing on adults with a formal diagnosis of panic disorder with or without agoraphobia. We considered the following psychological therapies: psychoeducation (PE), supportive psychotherapy (SP), physiological therapies (PT), behaviour therapy (BT), cognitive therapy (CT), cognitive behaviour therapy (CBT), third-wave CBT (3W) and psychodynamic therapies (PD). We included both individual and group formats. Therapies had to be administered face-to-face. The

    This study attempted to replicate previous reports of associations between panic disorder and joint hyperlaxity. The authors also examined possible associations between reacitivity to carbon dioxide (CO(2)), a model for panic vulnerability, and hyperlaxity in healthy volunteers. One hundred and one patients with DSM-IV panic disorder and 39 healthy volunteers were assessed for hyperlaxity by Beighton's criteria. Healthy volunteers also received two vital capacity inhalations of CO(2). Thirteen (13%) patients had five or more hyperlax joints. This rate did not differ from that in the healthy volunteers. Anxiety in healthy volunteers, as measured by the NIMH self-rating scale, DSM-IV panic symptom scores, and 100 mm visual analog scales of anxiety, increased after CO(2) from a mean of 1.8 to 2.8 (not significant); from 0.5 to 4 ( p < 0.001) and from 8.7 to 11.6 mm ( p < 0.1), respectively. There were no associations between responses to CO(2) and hyperlaxity. Copyright 2001 John Wiley & Sons, Ltd.

    Aim Inconsistent results continue to be reported in studies that examine the neural correlates of cognitive behavioral therapy (CBT) in patients with panic disorder. We examined the changes in regional cerebral blood flow (rCBF) associated with the alleviation of anxiety by CBT in panic patients. Methods The change in rCBF and clinical symptoms before and after CBT were assessed using single photon emission computed tomography and various clinical measures were analyzed. Results Fourteen subjects who completed CBT showed significant improvements in symptoms on clinical measures, including the Panic and Agoraphobic Scale and the Anxiety Sensitivity Index-Revised. After CBT, increased rCBF was detected in the left postcentral gyrus (BA 43), left precentral gyrus (BA 4), and left inferior frontal gyrus (BA 9 and BA 47), whereas decreased rCBF was detected in the left pons. Correlation analysis of the association between the changes in rCBF and changes in each clinical measure did not show significant results. Conclusion We found changes in the rCBF associated with the successful completion of CBT. The present findings may help clarify the effects of CBT on changes in brain activity in panic disorder.

    Full Text Available Physicians who encounter patients in the emergency department with chest pain, palpitations, or shortness of breath may often find it difficult to differentiate diagnosis of panic attacks from acute coronary syndrome or Takotsubo Cardiomyopathy. Redefining and understanding the pathophysiological relationship of psychiatric illness including anxiety, depression, or panic attacks and Takotsubo Cardiomyopathy may help clinicians implement a more effective and beneficial model of care for this affliction that is being found to be increasingly more common in today’s age.

    The Prokaryotic Operon DataBase (ProOpDB, http://operons.ibt.unam.mx/OperonPredictor) constitutes one of the most precise and complete repositories of operon predictions now available. Using our novel and highly accurate operon identification algorithm, we have predicted the operon structures of more than 1200 prokaryotic genomes. ProOpDB offers diverse alternatives by which a set of operon predictions can be retrieved including: (i) organism name, (ii) metabolic pathways, as defined by the KEGG database, (iii) gene orthology, as defined by the COG database, (iv) conserved protein domains, as defined by the Pfam database, (v) reference gene and (vi) reference operon, among others. In order to limit the operon output to non-redundant organisms, ProOpDB offers an efficient method to select the most representative organisms based on a precompiled phylogenetic distances matrix. In addition, the ProOpDB operon predictions are used directly as the input data of our Gene Context Tool to visualize their genomic context and retrieve the sequence of their corresponding 5' regulatory regions, as well as the nucleotide or amino acid sequences of their genes.

  4. Non-disruptive tactics of suppression are superior in countering terrorism, insurgency, and financial panics.

    Directory of Open Access Journals (Sweden)

    David A Siegel

    Full Text Available BACKGROUND: Suppressing damaging aggregate behaviors such as insurgency, terrorism, and financial panics are important tasks of the state. Each outcome of these aggregate behaviors is an emergent property of a system in which each individual's action depends on a subset of others' actions, given by each individual's network of interactions. Yet there are few explicit comparisons of strategies for suppression, and none that fully incorporate the interdependence of individual behavior. METHODS AND FINDINGS: Here I show that suppression tactics that do not require the removal of individuals from networks of interactions are nearly always more effective than those that do. I find using simulation analysis of a general model of interdependent behavior that the degree to which such less disruptive suppression tactics are superior to more disruptive ones increases in the propensity of individuals to engage in the behavior in question. CONCLUSIONS: Thus, hearts-and-minds approaches are generally more effective than force in counterterrorism and counterinsurgency, and partial insurance is usually a better tactic than gag rules in quelling financial panics. Differences between suppression tactics are greater when individual incentives to support terrorist or insurgent groups, or susceptibilities to financial panic, are higher. These conclusions have utility for policy-makers seeking to end bloody conflicts and prevent financial panics. As the model also applies to mass protest, its conclusions provide insight as well into the likely effects of different suppression strategies undertaken by authoritarian regimes seeking to hold on to power in the face of mass movements seeking to end them.

    UTC(OP), the French national realization of the international coordinated universal time, was redesigned and rebuilt. The first step was the implementation in October 2012 of a new algorithm based on a H-maser and on atomic fountain data. Thanks to the new implementation, the stability of UTC(OP) was dramatically improved and UTC(OP) competes with the best time scales available today. Then the hardware generation and distribution of the UTC(OP) physical signals were replaced. Part of the new hardware is composed of commercial devices, but the key elements were specifically developed. One of them is a special switch that allows the UTC(OP) signals to be derived from one of two time scales, based on two different H-masers, which are generated simultaneously. This insures the continuity of the UTC(OP) signal even when a change of the reference H-maser is required. With the new hardware implementation, UTC(OP) is made available through three coherent signals: 100 MHz, 10 MHz and 1 PPS. For more than 3 years, UTC(OP) remained well below 10 ns close to UTC, with a difference even less than 5 ns if we except a short period around MJD 56650. (authors)

  11. Proposal of a model for sales and operations planning (S&OP maturity evaluation

    2017-11-01

    Full Text Available Abstract A successful S&OP implementation can bring many benefits to organizations, and after its implementation, the S&OP process can evolve and reach higher levels of maturity. Considering that, only through a measurement system, goals and benefits can be achieved, thus, it is essential to assess S&OP maturity level. Many papers on literature adopt a quantitative perspective on S&OP, but just few of them deal with uncertainty present in S&OP decision-making, such as maturity model assessment process that carries subjectivity and uncertainty. Thus, this study proposes a decision making model based on fuzzy theory to evaluate and to categorize S&OP maturity levels and to suggest strategies to increase S&OP maturity. A pilot application was conducted in two manufacturing organizations that have implemented the S&OP process. The results, according to the performance presented, suggest different actions must be taken in terms of ensuring enablers to S&OP implementation.

    Reimbursement for inpatient services rendered based on comparable daily care rates, case-based flat rates, and special fees as practiced until now has been replaced by the system of diagnosis-related groups. Up until 2004, operation and procedure system (OPS 301) codes could be processed completely automatically by appropriate adaptation of the radiology information system (RIS). Because of further differentiation of OPS codes in the 2005 version, it is no longer possible to unambiguously determine OPS codes automatically. Our goal was to fulfill these additional requirements with as little extra effort as possible. In 36 of 2138 procedures during an observation period of 12 days, i.e., 4/day, manual input on the part of the radiology technical assistant and quality assurance by the diagnosing physician were necessary. This is only needed in complicated procedures for which the minor added effort is negligible in comparison to the entire effort expended for the procedure. We were thus able to achieve the goal of near automation of ascertaining OPS codes. (orig.) [German] Die bisherige Erstattung stationaerer Krankenhausleistungen auf Basis tagesgleicher Pflegesaetze, Fallpauschalen und Sonderentgelte ist durch das Diagnosis-related-groups- (DRG-)System abgeloest worden. Operationen- und Prozeduren- (OPS-)Schluessel 301 konnten in der Radiologie bis 2004 mit entsprechender Anpassung des ''Radiologie-Informations-System'' (RIS) vollautomatisiert erfasst werden. Durch die immer feinere Differenzierung der OPS-Codes in der Version 2005 ist eine eindeutige Ermittlung der OPS-Codes jedoch nicht mehr vollautomatisch moeglich. Ziel ist es, diese zusaetzlichen Aufgaben mit so wenig Mehraufwand wie moeglich zu erbringen. Bei 36 von 2138 Verfahren waren in einem Beobachtungszeitraum von 12 Tagen, d. h. 4/Tag, manuelle Eingaben durch die MTRA sowie eine Qualitaetskontrolle durch den befundenden Arzt notwendig.

    This naturalistic open label follow-up study had three objectives: 1) To observe the course of illness in Panic Disorder patients receiving long-term versus intermediate-term paroxetine treatment, 2) To compare the relapse rates and side-effect profile after long-term paroxetine treatment between patients with Panic Disorder and Panic Disorder with Agoraphobia, 3) To observe paroxetine's tolerability over a 24 month period. 143 patients with panic disorder (PD), with or without agoraphobia, successfully finished a short-term (ie 12 week) trial of paroxetine treatment. All patients then continued to receive paroxetine maintenance therapy for a total of 12 months. At the end of this period, 72 of the patients chose to discontinue paroxetine pharmacotherapy and agreed to be monitored throughout a one year discontinuation follow-up phase. The remaining 71 patients continued on paroxetine for an additional 12 months and then were monitored, as in the first group, for another year while medication-free. The primary limitation of our study is that the subgroups of patients receiving 12 versus 24 months of maintenance paroxetine therapy were selected according to individual patient preference and therefore were not assigned in a randomized manner. Only 21 of 143 patients (14%) relapsed during the one year medication discontinuation follow-up phase. There were no significant differences in relapse rates between the patients who received intermediate-term (up to 12 months) paroxetine and those who chose the long-term course (24 month paroxetine treatment). 43 patients (30.1%) reported sexual dysfunction. The patients exhibited an average weight gain of 5.06 kg. All patients who eventually relapsed demonstrated significantly greater weight increase (7.3 kg) during the treatment phase. The extension of paroxetine maintenance treatment from 12 to 24 months did not seem to further decrease the risk of relapse after medication discontinuation. Twenty-four month paroxetine

    The objective of this study is to ascertain the rates of social phobia, panic disorder and suicidality in the midst of the manic state among subjects with pure and depressive mania. Subjects received evaluations entailing the use of serial standard clinical interviews, the Schedule for Affective Disorders and Schizophrenia (SADS) and a structured interview to determine whether they met the criteria for intra-episode social phobia (IESP) and panic disorder (IEPD). The diagnoses of major depressive disorder and mania were rendered using the Research Diagnostic Criteria. The diagnoses of IESP and IEPD were rendered using DSM-III-R criteria. Categorization as being suicidal was based on the SADS suicide subscale score. Twenty-five (56.8%) subjects had pure and 19 (43.2%) subjects had depressive mania. None of the subjects with pure and 13 (68.4%) with depressive mania had IESP (Pdepressive mania had IEPD (Pdepressive were suicidal. Twelve of 13 (92.3%) subjects with depressive mania met the criteria for IESP and IEPD concurrently (Pdepressive but not pure mania exhibited high rates of both IESP and IEPD. Concurrence of the disorders is the rule. The findings suggest that databases disclosing a relationship between panic disorder and suicidality merit, where possible, reanalysis directed at controlling for the effect of social phobia.

    2009-05-01

    The purpose of this study was to examine associations between abortion history and a wide range of anxiety (panic disorder, panic attacks, PTSD, Agoraphobia), mood (bipolar disorder, mania, major depression), and substance abuse disorders (alcohol and drug abuse and dependence) using a nationally representative US sample, the national comorbidity survey. Abortion was found to be related to an increased risk for a variety of mental health problems (panic attacks, panic disorder, agoraphobia, PTSD, bipolar disorder, major depression with and without hierarchy), and substance abuse disorders after statistical controls were instituted for a wide range of personal, situational, and demographic variables. Calculation of population attributable risks indicated that abortion was implicated in between 4.3% and 16.6% of the incidence of these disorders. Future research is needed to identify mediating mechanisms linking abortion to various disorders and to understand individual difference factors associated with vulnerability to developing a particular mental health problem after abortion.

    To identify variables predicting psychotherapy outcome for panic disorder or indicating which of 2 very different forms of psychotherapy-panic-focused psychodynamic psychotherapy (PFPP) or cognitive-behavioral therapy (CBT)-would be more effective for particular patients. Data were from 161 adults participating in a randomized controlled trial (RCT) including these psychotherapies. Patients included 104 women; 118 patients were White, 33 were Black, and 10 were of other races; 24 were Latino(a). Predictors/moderators measured at baseline or by Session 2 of treatment were used to predict change on the Panic Disorder Severity Scale (PDSS). Higher expectancy for treatment gains (Credibility/Expectancy Questionnaire d = -1.05, CI 95% [-1.50, -0.60]), and later age of onset (d = -0.65, CI 95% [-0.98, -0.32]) were predictive of greater change. Both variables were also significant moderators: patients with low expectancy of improvement improved significantly less in PFPP than their counterparts in CBT, whereas this was not the case for patients with average or high levels of expectancy. When patients had an onset of panic disorder later in life (≥27.5 years old), they fared as well in PFPP as CBT. In contrast, at low and mean levels of onset age, CBT was the more effective treatment. Predictive variables suggest possibly fruitful foci for improvement of treatment outcome. In terms of moderation, CBT was the more consistently effective treatment, but moderators identified some patients who would do as well in PFPP as in CBT, thereby widening empirically supported options for treatment of this disorder.

    Pedestrian movement is the one of the subset for the crowd management under simulation objective. During panic situation, pedestrian usually will create a microscopic movement that lead towards the self-organization. During self-organizing, the behavioral and physical factors had caused the mass effect on the pedestrian movement. The basic CA model will create a movement path for each pedestrian over a time step. However, due to the factors immerge, the CA model needs some enhancement that will establish a real simulation state. Hence, this concept paper will discuss on the enhanced features of CA model for microscopic pedestrian movement during panic situation for a better pedestrian simulation.

  9. OP9 bone marrow stroma cells differentiate into megakaryocytes and platelets.

    Directory of Open Access Journals (Sweden)

    Yumiko Matsubara

    Full Text Available Platelets are essential for hemostatic plug formation and thrombosis. The mechanisms of megakaryocyte (MK differentiation and subsequent platelet production from stem cells remain only partially understood. The manufacture of megakaryocytes (MKs and platelets from cell sources including hematopoietic stem cells and pluripotent stem cells have been highlighted for studying the platelet production mechanisms as well as for the development of new strategies for platelet transfusion. The mouse bone marrow stroma cell line OP9 has been widely used as feeder cells for the differentiation of stem cells into MK lineages. OP9 cells are reported to be pre-adipocytes. We previously reported that 3T3-L1 pre-adipocytes differentiated into MKs and platelets. In the present study, we examined whether OP9 cells differentiate into MKs and platelets using MK lineage induction (MKLI medium previously established to generate MKs and platelets from hematopoietic stem cells, embryonic stem cells, and pre-adipocytes. OP9 cells cultured in MKLI medium had megakaryocytic features, i.e., positivity for surface markers CD41 and CD42b, polyploidy, and distinct morphology. The OP9-derived platelets had functional characteristics, providing the first evidence for the differentiation of OP9 cells into MKs and platelets. We then analyzed gene expressions of critical factors that regulate megakaryopoiesis and thrombopoiesis. The gene expressions of p45NF-E2, FOG, Fli1, GATA2, RUNX1, thrombopoietin, and c-mpl were observed during the MK differentiation. Among the observed transcription factors of MK lineages, p45NF-E2 expression was increased during differentiation. We further studied MK and platelet generation using p45NF-E2-overexpressing OP9 cells. OP9 cells transfected with p45NF-E2 had enhanced production of MKs and platelets. Our findings revealed that OP9 cells differentiated into MKs and platelets in vitro. OP9 cells have critical factors for megakaryopoiesis and

    The world now faces the dreadful possibility of biological weapons attacks by terrorists. Healthcare systems would have to cope with such emergencies should all preemptive measures fail. Information gained from the Global Mercury exercise and the SARS outbreak has shown that containing an outbreak at the start is more effective than reacting to it once it has spread and that containment should be treated both nationally and internationally. On the national level this entails developing rapid and effective methods to detect and identify infected cases, and implementing isolation and control measures to lower the risk of further transmission of the disease while assuring the safety of medical teams and laboratory workers. Strategic contingency plans should incorporate well-defined procedures for hospitalization and isolation of patients, providing regional backup of medical personnel and equipment and maintaining close cooperation between the various bodies in the healthcare system. Quarantine is an effective containment measure, especially if voluntarily imposed. Modern communication systems can help by sending professional teams timely instructions and providing the public with information to reduce panic and stress during quarantine procedures. Informing the public poses a dilemma: finding a balance between giving advance warning of an imminent epidemic outbreak and ascertaining the likelihood of its occurrence. Containment of international bioterrorist attacks depends entirely on close international cooperation to implement national and international strategic contingency plans with free exchange of information and recognition of procedures.

  13. Relations among symptoms of social phobia subtypes, avoidant personality disorder, panic, and depression.

    Carter, Shawn A; Wu, Kevin D

    2010-03-01

    This study's primary goal was to examine relations between symptoms of specific social phobia (SSP), generalized social phobia (GSP), avoidant personality disorder (APD), and panic and depression. Past research has suggested a single social phobia continuum in which SSP displays less symptom severity than GSP or APD. We found SSP symptoms correlated less strongly with depression but more strongly with panic relative to both GSP and APD symptoms. These findings challenge a unidimensional model of social phobia, suggesting a multidimensional model may be more appropriate. These findings also inform current research aimed at classifying mood and anxiety disorders more broadly by identifying that the different factors of fear versus distress appear to underlie different subtypes of social phobia. 2008.

  15. The Trojan Horse Method as a tool to investigate low-energy resonances: the 18O(p, α)15N and 17O(p, α)14N cases

    The 18 O(p, α) 15 N and 17 O(p, α) 14 N reactions are of primary importance in several as-trophysical scenarios, including nucleosynthesis inside Asymptotic Giant Branch stars and oxygen and nitrogen isotopic ratios in meteorite grains. They are also key reactions to understand exotic systems such as R-Coronae Borealis stars and novae. Thus, the measurement of their cross sections in the low energy region can be crucial to reduce the nuclear uncertainty on theoretical predictions, because the resonance parameters are poorly determined. The Trojan Horse Method, in its newly developed form particularly suited to investigate low-energy resonances, has been applied to the 2 H( 18 O, α 15 N)n and 2 H( 17 O, α 14 N)n reactions to deduce the 18 O(p, α) 15 N and 17 O(p, α) 14 N cross sections at low energies. Resonances in the 18 O(p, α) 15 N and 17 O(p, α) 14 N excitation functions have been studied and the resonance parameters deduced.

  16. The moral panic about the socializing of young people in Minangkabau

    2013-04-01

    Full Text Available This paper analyses the discourse surrounding the perceived threat of free seks and pergaulan bebas (free socializing to the moral health of young Minangkabau people, and in particular, young women, in West Sumatra. It uses the sociological frame of “moral panic” to examine contemporary discussions about globalization and the influence of “the West” in West Sumatra. The paper examines the way in which “the authorities” in West Sumatra (media, such as teen magazines and newspapers, academics, government and law, teachers, and community leaders present the threat, and the way in which young people, who are the target of the moral panic onslaught, see themselves in relation to the threat. I argue that, unlike the original “folk devils” of the moral panics in Britain, young people in Minangkabau broadly give their consent to the authorities, displaying a striking commitment to social conservatism, local culture, and Islamic values.

    2014-01-01

    This study explored the automatic and controlled processes that may influence performance on an implicit measure across cognitive-behavioral group therapy for panic disorder. The Quadruple Process model was applied to error scores from an Implicit Association Test evaluating associations between the concepts Me (vs. Not Me) + Calm (vs. Panicked) to evaluate four distinct processes: Association Activation, Detection, Guessing, and Overcoming Bias. Parameter estimates were calculated in the panic group (n = 28) across each treatment session where the IAT was administered, and at matched times when the IAT was completed in the healthy control group (n = 31). Association Activation for Me + Calm became stronger over treatment for participants in the panic group, demonstrating that it is possible to change automatically activated associations in memory (vs. simply overriding those associations) in a clinical sample via therapy. As well, the Guessing bias toward the calm category increased over treatment for participants in the panic group. This research evaluates key tenets about the role of automatic processing in cognitive models of anxiety, and emphasizes the viability of changing the actual activation of automatic associations in the context of treatment, versus only changing a person's ability to use reflective processing to overcome biased automatic processing.

    In this paper, we present the VOLNA-OP2 tsunami model and implementation; a finite volume non-linear shallow water equations (NSWE) solver built on the OP2 domain specific language for unstructured mesh computations. VOLNA-OP2 is unique among tsunami solvers in its support for several high performance computing platforms: CPUs, the Intel Xeon Phi, and GPUs. This is achieved in a way that the scientific code is kept separate from various parallel implementations, enabling easy maintainability. It has already been used in production for several years, here we discuss how it can be integrated into various workflows, such as a statistical emulator. The scalability of the code is demonstrated on three supercomputers, built with classical Xeon CPUs, the Intel Xeon Phi, and NVIDIA P100 GPUs. VOLNA-OP2 shows an ability to deliver productivity to its users, as well as performance and portability on a number of platforms.

    2008-01-01

    The highly prevalent psychiatric disorders dysthymia and panic disorder have often a chronic or recurrent course with superimposed major depression. The prominent comorbidity between these diagnoses constitutes a confounding factor in the study of long-term outcome. We performed a 9-year follow-up of 38 patients with "pure" diagnoses, i.e. without comorbid dysthymia and panic disorder, selected from two 2-year naturalistic treatment studies with psychotherapy and antidepressant medication. The aims of the present study were to investigate 1) the stability of change, and 2) the impact of comorbid personality disorders (PDs) on long-term outcome. Patients were reassessed with SCID-I and SCID-II interviews, SCL-90/BSI and a detailed, modified life-charting interview, investigating course and treatment over time. About 50% of patients showed substantial improvement, of whom about half were in remission. Comorbid PD was a negative prognostic factor independently of Axis I diagnosis. Although patients with panic disorder had a lower frequency of comorbid PD, later onset, shorter duration of illness and better outcome after the original studies, there was no difference in the long-term outcome. The less stable outcome among panic patients suggests that standard treatments are not resulting in enduring remission. In order to achieve remission, it is necessary to 1) address comorbid PDs, 2) perform careful assessments of all comorbid diagnoses, and 3) build routines for the follow-up and augmentation of treatments.

    In this paper we show that distinguisher on CBC-MAC can be applied to Encrypted Message Authentication Code (EMAC) scheme. EMAC scheme in general is vulnerable to distinguishing attack and second preimage attack. Distinguishing attack simulation on AES-EMAC using 225 message modifications, no collision have been found. According to second preimage attack simulation on AES-EMAC no collision found between EMAC value of S1 and S2, i.e. no second preimage found for messages that have been tested. Based on distinguishing attack simulation on truncated AES-EMAC we found collision in every message therefore we cannot distinguish truncated AES-EMAC with random function. Second-preimage attack is successfully performed on truncated AES-EMAC.

    2007-12-01

    Full Text Available Abstract Background In a number of drug and psychotherapy comparative trials, psychotherapy-placebo combination has been assumed to represent psychotherapy. Whether psychotherapy plus pill placebo is the same as psychotherapy alone is an empirical question which however has to date never been examined systematically. Methods We conducted a systematic review and meta-analysis of randomised controlled trials (RCTs that directly compared cognitive-behavior therapy (CBT alone against CBT plus pill placebo in the treatment of panic disorder. Results Extensive literature search was able to identify three relevant RCTs. At the end of the acute phase treatment, patients who received CBT plus placebo had 26% (95%CI: 2 to 55% increased chances of responding than those who received CBT alone. At follow-up the difference was no longer statistically significant (22%, 95%CI: -10% to 64%. Conclusion The act of taking a pill placebo may enhance the placebo effect already contained in the effective psychotherapeutic intervention during the acute phase treatment. Theoretically this is an argument against the recently claimed null hypothesis of placebo effect in general and clinically it may point to some further room for enhancing the psychotherapeutic approach for panic disorder.

  19. The animal body, violence and moral panic: The case of Mila the dog

    Directory of Open Access Journals (Sweden)

    Žakula Sonja

    2014-01-01

    Full Text Available In April of 2010 Serbia was rocked by the news that a dog whose paws had been cut off was found in the Medakovic neighborhood of Belgrade. Miraculously, the dog was still alive, but in bad condition. The news media named the dog Mila (which, aside from being a Serbian female name, can also mean “dear one” or “gentle one” and the Serbian public followed the story of Mila’s plight and subsequent recovery with great interest and much comment, so much so that the event became a trigger for a moral panic of sorts. In this paper I have attempted to point out how the Serbian public, with reference to the case of Mila the dog, conceptualizes violence against animals, as well as to point out that folk classifications of living creatures - such as the one which distinguishes animals from meat (see Mullin 1999 - influence the understanding and conceptualization of violence as a phenomenon. Secondly, I have attempted to uncover which elements of the event in question caused a moral panic in Serbia, and which had inhibited the development of a serious public discussion of the issue of animal suffering. In that sense, the object of this paper is twofold - on the one hand it aims to point out why a discussion of the systematic and systemic violence against animals did not occur, and on the other, it serves to point out those elements of the event which caused the panic.

    This study investigated five-factor model personality traits in anxiety (simple phobia, social phobia, agoraphobia, and panic disorder) and major depressive disorders in a population-based sample. In the Baltimore Epidemiologic Catchment Area Follow-up Study, psychiatrists administered the Schedules for Clinical Assessment in Neuropsychiatry to 333 adult subjects who also completed the Revised NEO Personality Inventory. All of the disorders except simple phobia were associated with high neuroticism. Social phobia and agoraphobia were associated with low extraversion. In addition, lower-order facets of extraversion, agreeableness, and conscientiousness were associated with certain disorders (i.e., low positive emotions in panic disorder; low trust and compliance in certain phobias; and low competence, achievement striving, and self-discipline in several disorders). This study emphasizes the utility of lower-order personality assessments and underscores the need for further research on personality/psychopathology etiologic relationships.

    Full Text Available Purpose: The purpose of this paper is to develop and compare two co-op advertising models: advertising model under traditional channel and co-op advertising model under dual channel, to select optimal channel structure to sell products for manufacturer and to derive optimal co-op advertising strategies for the manufacturer and the retailer.Design/methodology/approach: Stackelberg game theoretical is used to develop two co-op advertising models: co-op advertising model under traditional channel and co-op advertising model under dual channel. Then we compare the two models to select optimal channel structure to sell products for manufacturer and to derive optimal co-op advertising strategies for the manufacturer and the retailer. Furthermore, we analyze the impact of product web-fit on these optimal strategies and illustrate by some numeral examples. Based on our results, we provide some significant theories and managerial insights, and derive some probable paths of future research.Findings: We provide a framework for researching optimal co-op advertising strategies in a two-level supply chain considering different marketing channel structures. First, we discuss the traditional channel co-op adverting model and the dual channel co-op advertising model based on Stackelberg game theoretical, and we derive optimal co-op advertising strategies. Next, comparisons of these two channel structures are discussed and we find that the manufacturer always benefits from dual channel. But the retailer not always benefits from dual channel structure, and dual channel structure is better than retail channel with certain conditions. Also, the optimal co-op advertising strategies for the manufacturer and the retailer are obtained.Research limitations/implications: First, we focus on the aforementioned two channel structures; a further comparison with other channel structures can be investigated. Second, we ignore some factors that influence the demand of product

    2004-06-01

    A successful attack strategy in neural cryptography is presented. The neural cryptosystem, based on synchronization of neural networks by mutual learning, has been recently shown to be secure under different attack strategies. The success of the advanced attacker presented here, called the "majority-flipping attacker," does not decay with the parameters of the model. This attacker's outstanding success is due to its using a group of attackers which cooperate throughout the synchronization process, unlike any other attack strategy known. An analytical description of this attack is also presented, and fits the results of simulations.

    Patients with panic disorder with agoraphobia (PDA) have clinical symptoms such as the fear of being outside or of open spaces from which escape would be difficult. Although recent neurobiological studies have suggested that fear conditioning and extinction are associated with PDA, no study has examined the possible structural abnormalities in patients with PDA. This preliminary study compares the gray matter volume among patients with PDA, those with panic disorder without agoraphobia (PDW), and healthy controls (HC) using high-resolution 3.0 T magnetic resonance imaging (MRI) with voxel-based morphometry (VBM). Compared with HC, patients with PDA showed decreased gray matter volume in their left medial orbitofrontal gyrus. However, differences were not found in the gray matter volumes of patients with PDW and whole panic disorder compared with HC. These findings suggest that the phobic avoidance found in patients with PDA arise from abnormalities in the medial orbitofrontal cortex, which plays an important role in fear extinction. Future studies should investigate the neuroanatomical substrates of PDA and distinguish them from those of PDW. Copyright © 2013 Elsevier Inc. All rights reserved.

    Replication has been difficult to achieve in linkage studies of psychiatric disease. Linkage studies of panic disorder have indicated regions of interest on chromosomes 1q, 2p, 2q, 3, 7, 9, 11, 12q13, 12q23, and 15. Few regions have been implicated in more than one study. We examine two samples, the Iowa (IA) and the Columba panic disorder families. We use the fuzzy-clustering method presented by Kaabi et al. [Kaabi et al. (2006); Am J Hum Genet 78: 543-553] to summarize liability to panic disorder, agoraphobia, simple phobia, and social phobia. Kaabi et al. applied this method to the Yale panic disorder linkage families and found evidence of linkage to chromosomes 4q21, 4q32, 7p, and 8. When we apply the same method to the IA families, we obtain overlapping evidence of linkage to chromosomes 4q21 and 7p. Additionally, we find evidence of linkage on chromosomes 1, 5, 6, 16, and 22. The Columbia (CO) data does not indicate linkage to any of the Kaabi et al. peaks, instead implicating chromosomes 2 and 22q11 (2 Mb from COMT). There is some evidence of overlapping linkage between the IA and CO datasets on chromosomes 1 and 14. While use of fuzzy clustering has not produced complete concordance across datasets, it has produced more than previously seen in analyses of panic disorder proper. We conclude that chromosomes 4q21 and 7p should be considered strong candidate regions for panic and fear-associated anxiety disorder loci. More generally, this suggests that analyses including multiple aspects of psychopathology may lead to greater consistency across datasets. Copyright © 2012 Wiley Periodicals, Inc.

    The cactus OpsDHN1 dehydrin belongs to a large family of disordered and highly hydrophilic proteins known as Late Embryogenesis Abundant (LEA) proteins, which accumulate during the late stages of embryogenesis and in response to abiotic stresses. Herein, we present the in vivo OpsDHN1 subcellular localization by N-terminal GFP translational fusion; our results revealed a cytoplasmic and nuclear localization of the GFP::OpsDHN1 protein in Nicotiana benthamiana epidermal cells. In addition, dimer assembly of OpsDHN1 in planta using a Bimolecular Fluorescence Complementation (BiFC) approach was demonstrated. In order to understand the in vivo role of the histidine-rich motif, the OpsDHN1-ΔHis version was produced and assayed for its subcellular localization and dimer capability by GFP fusion and BiFC assays, respectively. We found that deletion of the OpsDHN1 histidine-rich motif restricted its localization to cytoplasm, but did not affect dimer formation. In addition, the deletion of the S-segment in the OpsDHN1 protein affected its nuclear localization. Our data suggest that the deletion of histidine-rich motif and S-segment show similar effects, preventing OpsDHN1 from getting into the nucleus. Based on these results, the histidine-rich motif is proposed as a targeting element for OpsDHN1 nuclear localization. PMID:26442018

  2. Composite Dos Attack Model

    2012-04-01

    Full Text Available Preparation for potential threats is one of the most important phases ensuring system security. It allows evaluating possible losses, changes in the attack process, the effectiveness of used countermeasures, optimal system settings, etc. In cyber-attack cases, executing real experiments can be difficult for many reasons. However, mathematical or programming models can be used instead of conducting experiments in a real environment. This work proposes a composite denial of service attack model that combines bandwidth exhaustion, filtering and memory depletion models for a more real representation of similar cyber-attacks. On the basis of the introduced model, different experiments were done. They showed the main dependencies of the influence of attacker and victim’s properties on the success probability of denial of service attack. In the future, this model can be used for the denial of service attack or countermeasure optimization.

    Previous studies have demonstrated that acute poisoning from exposure to organophosphate (OP) pesticides in agricultural workers causes adverse health effects. However, neuropsychological and cognitive effects of chronic occupational exposure to OP pesticides remain controversial. To identify, evaluate, and systematize existing evidence regarding chronic exposure to OP pesticides and neuropsychological effects in farmworkers. Using the PubMed search engine, a systematic review process was implemented and replicated according to the PRISMA statement. Eligibility criteria included workers over 18 years of age exposed to OP pesticides as well as assessment of neuropsychological and cognitive functioning. Search terms were in English and Spanish languages and included organophosphate and workers. Of the search results, 33 of 1,256 articles meet eligibility criteria. Twenty-four studies found an association between chronic occupational exposure to OP pesticides and low neuropsychological performance in workers. We classified nine of the studies to have study design limitations. Studies indicated occupational exposure to OP pesticides is linked to difficulties in executive functions, psychomotor speed, verbal, memory, attention, processing speed, visual-spatial functioning, and coordination. Nine studies find no relationship between OP pesticides exposure and neuropsychological performance. Overall, evidence suggests an association between chronic occupational exposure to OP pesticides and neuropsychological effects. However, there is no consensus about the specific cognitive skills affected.

  10. OpWise: Operons aid the identification of differentially expressed genes in bacterial microarray experiments

    2006-01-01

    Full Text Available Abstract Background Differentially expressed genes are typically identified by analyzing the variation between replicate measurements. These procedures implicitly assume that there are no systematic errors in the data even though several sources of systematic error are known. Results OpWise estimates the amount of systematic error in bacterial microarray data by assuming that genes in the same operon have matching expression patterns. OpWise then performs a Bayesian analysis of a linear model to estimate significance. In simulations, OpWise corrects for systematic error and is robust to deviations from its assumptions. In several bacterial data sets, significant amounts of systematic error are present, and replicate-based approaches overstate the confidence of the changers dramatically, while OpWise does not. Finally, OpWise can identify additional changers by assigning genes higher confidence if they are consistent with other genes in the same operon. Conclusion Although microarray data can contain large amounts of systematic error, operons provide an external standard and allow for reasonable estimates of significance.

    Collective movement of animal in emergency condition has attracted growing attentions among researchers. However, many rules still need to be confirmed with adequate explanation. Study of collective behavior of mice can improve our understanding about the dynamics of pedestrian movement. However, its rules still need to be confirmed with adequate explanation. In this paper, collective behavior of mice passing through an exit under panic was investigated. The results showed that the total evacuation time decreased with exit width increasing in a certain range. Based on the different tendency of the curve in temporal evolution, the process of mice flow was divided into three stages. The density of mice near the exit peaks at a certain horizontal offset and starts to decrease over time. With the increase of the exit width, the duration of the higher density state decreased. We found that the frequency of time intervals obeyed a lognormal distribution or an exponential decay for different exit widths. In addition, the relationship between the group size and the group flow rate in different scenarios was analyzed. The phenomena found in our experiments show the collective behavioral characteristic of mice under panic. Our analysis in this paper will deepen our understanding of crowd dynamics in emergency condition.

    Full Text Available Multiple respiratory abnormalities can be found in anxiety disorders, especially in panic disorder (PD. Individuals with PD experience unexpected panic attacks, characterized by anxiety and fear, resulting in a number of autonomic and respiratory symptoms. Respiratory stimulation is a common event during panic attacks. The respiratory abnormality most often reported in PD patients is increased CO2 sensitivity, which has given rise to the hypothesis of fundamental abnormalities in the physiological mechanisms that control breathing in PD. There is evidence that PD patients with dominant respiratory symptoms are more sensitive to respiratory tests than are those who do not manifest such symptoms, and that the former group constitutes a distinct subtype. Patients with PD tend to hyperventilate and to panic in response to respiratory stimulants such as CO2, triggering the activation of a hypersensitive fear network. Although respiratory physiology seems to remain normal in these subjects, recent evidence supports the idea that they present subclinical abnormalities in respiration and in other functions related to body homeostasis. The fear network, composed of the hippocampus, the medial prefrontal cortex, the amygdala and its brain stem projections, might be oversensitive in PD patients. This theory might explain why medication and cognitive-behavioral therapy are both clearly effective. Our aim was to review the relationship between respiration and PD, addressing the respiratory subtype of PD and the hyperventilation syndrome, with a focus on respiratory challenge tests, as well as on the current mechanistic concepts and the pharmacological implications of this relationship.Múltiplas anormalidades respiratórias podem ser encontradas em pacientes com transtornos de ansiedade, particularmente no transtorno de pânico (TP.

    Anticipatory anxiety and harm avoidance are essential features of panic disorder (PD) and may involve deficits in the reward system of the brain, in particular in the ventral striatum. While neuroimaging studies on PD have focused on fearful and negative affective stimulus processing, no investigations have directly addressed deficits in reward and loss anticipation. To determine whether the ventral striatum shows abnormal neural activity in PD patients during anticipation of loss or gain, an event-related functional magnetic resonance imaging experiment using a monetary incentive delay task was employed in 10 patients with PD and 10 healthy controls. A repeated-measures ANOVA to identify effects of group (PD vs. Control) and condition (anticipation of loss vs. gain vs. neutral outcome) revealed that patients with PD showed significantly reduced bilateral ventral striatal activation during reward anticipation but increased activity during loss anticipation. Within the patient group, the degree of activation in the ventral striatum during loss-anticipation was positively correlated with harm avoidance and negatively correlated with novelty seeking. These findings suggest that behavioural impairments in panic disorder may be related to abnormal neural processing of motivational cues. Copyright © 2017 Elsevier B.V. All rights reserved.

We examined the changes in regional cerebral blood flow (rCBF associated with the alleviation of anxiety by CBT in panic patients.Methods: The change in rCBF and clinical symptoms before and after CBT were assessed using single photon emission computed tomography and various clinical measures were analyzed.Results: Fourteen subjects who completed CBT showed significant improvements in symptoms on clinical measures, including the Panic and Agoraphobic Scale and the Anxiety Sensitivity Index-Revised. After CBT, increased rCBF was detected in the left postcentral gyrus (BA 43, left precentral gyrus (BA 4, and left inferior frontal gyrus (BA 9 and BA 47, whereas decreased rCBF was detected in the left pons. Correlation analysis of the association between the changes in rCBF and changes in each clinical measure did not show significant results.Conclusion: We found changes in the rCBF associated with the successful completion of CBT. The present findings may help clarify the effects of CBT on changes in brain activity in panic disorder.Keyword: single photon emission computed tomography (SPECT, anxiety, neural correlate, brain activity

    Full Text Available Taking control over work related stress. Mindfulness destresses social workersStress is a major social problem. Due to the increasing workload and the content of the work, social workers are at risk to develop stress (symptoms. The physical and psychological consequences of prolonged stress are serious. By living healthy, optimize working conditions and applying mindfulness, stress can be reduced. Mindfulness is an effective and useful way to reduce stress. It increases the resistance of workers against stress, improves brainfunctions and therefore has a positive effect on the performance. These effects are great, but they are still weakly methodologically substantiated. A pilot project within the youthcare though, was enthusiastically received and proves to be effective against stress symptoms. The exercises that are part of this pilot fit well with the needs of employees. For organizations mindfulnesstrainings are a time-and cost-effective way of structural stress prevention.Grip op werkstress. Mindfulness ontstresst maatschappelijk werkersStress is een omvangrijk maatschappelijk probleem. Door de toenemende werkdruk en de inhoud van het werk zijn maatschappelijk werkers een risicogroep om stress en stressklachten te ontwikkelen. De fysieke en psychische gevolgen die langdurige stress met zich meebrengt zijn ernstig. Door gezond te leven, de arbeidsomstandigheden te optimaliseren en mindfulness toe te passen kan stress terug worden gedrongen. Mindfulness is een effectieve en bruikbare manier om stress te verminderen. Het vergroot de weerbaarheid van werknemers tegen stress, het verbetert de hersenwerking en heeft daardoor een positief effect op het functioneren. Grote effecten dus, maar wel nog methodologisch zwak onderbouwd. Een pilot binnen de jeugdzorg op het gebied van mindfulness is enthousiast ontvangen en blijkt effectief tegen stressklachten.

    Panic disorder (PD) is associated with significant personal, social, and economic costs. However, little is known about specific interpersonal dysfunctions that characterize the PD population. The current study systematically examined these interpersonal dysfunctions. The present analyses included 194 patients with PD out of a sample of 201 who were randomized to cognitive-behavioral therapy, panic-focused psychodynamic psychotherapy, or applied relaxation training. Interpersonal dysfunction was measured with the Inventory of Interpersonal Problems-Circumplex (Horowitz, Alden, Wiggins, & Pincus, 2000). Individuals with PD reported greater levels of interpersonal distress than that of a normative cohort (especially when PD was accompanied by agoraphobia), but lower than that of a cohort of patients with major depression. There was no single interpersonal profile that characterized PD patients. Symptom-based clusters (with vs. without agoraphobia) could not be discriminated on core or central interpersonal problems. Rather, as revealed by cluster analysis based on the pathoplasticity framework, there were 2 empirically derived interpersonal clusters among PD patients that were not accounted for by symptom severity and were opposite in nature: domineering-intrusive and nonassertive. The empirically derived interpersonal clusters appear to be of clinical utility in predicting alliance development throughout treatment: Although the domineering-intrusive cluster did not show any changes in the alliance throughout treatment, the nonassertive cluster showed a process of significant strengthening of the alliance. Empirically derived interpersonal clusters in PD provide clinically useful and nonredundant information about individuals with PD. (c) 2015 APA, all rights reserved).

    Full Text Available This paper specifically addresses linkage, a characteristically Brahmsian technique employed in the formation of musical ideas through the gradual transformation of precedent elements, being considered an indicator in the use of developing variation. After a detailed review of the literature encompassing definitions, classification and exemplification considering works of three theorists (FRISCH, 1984. SMITH, 2007. RAHN, 2015, an original proposal for a typology of linkage is presented. We compare a special occurrence of linkage in Brahms’ Violin Sonata, op. 78 to two similar occurrences in Leopoldo Miguéz’s sonata op. 14, a work of the same genre.. The results reinforce the hypothesis that Miguéz had employed organic constructive processes in his piece.

    12, however, there were no statistically significant differences between the 4 groups in relapse rates (defined as the occurrence of 1 or more panic attacks during the previous week of treatment) (F1,127 = 0.17; P = 0.13 [not statistically significant]). At the 12th month end point, patients in all 4 treatment groups had a statistically significant increase in body weight. Body weight among the study population increased by 6.1 + 4.9 kg from a mean weight of 72.4 + 7.3 kg at the onset of treatment. Reports of sexual adverse effects at the 12th month visit were similar in the citalopram, fluoxetine, and paroxetine groups, but the fluvoxamine patient group reported fewer sexual adverse effects at the 12th month visit. Most of our PD patients responded well to 12-month treatment with either citalopram, fluoxetine, fluvoxamine, or paroxetine, and the overall response rate was equal after the first 4 weeks of treatment. Although patients treated with paroxetine had the lowest dropout rates during the initiation phase, they had the highest rate of adverse effects as measured at the 12th month visit. Conversely, patients in the fluvoxamine group had the highest dropout rate (which was primarily caused by adverse effects in the initiation phase of treatment.); however, patients who were able to tolerate fluvoxamine throughout the full course of the study were observed to have lower rates of sexual dysfunction and weight gain compared with patients treated with the other agents. Overall, when measured at the 12th month visit, monotherapy with paroxetine and citalopram was associated with a higher rate of sexual adverse effects than was treatment with fluoxetine or fluvoxamine. In addition, monotherapy with paroxetine, citalopram, and fluoxetine seemed to cause more weight gain than did treatment with fluvoxamine.

    Despite developments in panic disorder (PD) research, a significant percentage of patients do not benefit from conventional treatments. Interpersonal factors have been identified as potential predictors of treatment failures. We aimed to evaluate assertiveness in a sample of patients with PD and its implications for treatment. Forty-six symptomatic patients with PD and 46 college students responded to assessment scales regarding assertiveness and clinical data. Seventy-five percent of the patients had a secondary diagnosis of agoraphobia. We found that the PD group was characterized as nonassertive and slightly less assertive than control subjects. Furthermore, the deficit in the level of assertiveness correlated with the severity of the PD. The diagnosis of agoraphobia was correlated with unassertiveness (p assertiveness in patients with PD accompanied by agoraphobia.

    Full Text Available Carolina Píparo was shot a few minutes after withdrawing cash from a bank branch. This case outraged the public opinion because she was eight months pregnant at the moment of the assault. She had to undergo a caesarean section and her baby only survived one week. Through an exploratory and inductive research we will analyze how the Argentine newspapers presented the case. We aim at elaborating a content analysis code book that can be validated in future similar researches on the subject. We apply the Framing theory in order to detect the frames used in the news coverage and to observe if they are compatible with the idea of «moral panic» proposed by Stanley Cohen.

Traditional theoretical analysis of cryptographic devices is based on black-box models which do not take into account the attacks on the implementations, known as physical attacks....... In practice such attacks can be executed easily, e.g. by heating the device, as substantiated by numerous works in the past decade. Tampering attacks are a class of such physical attacks where the attacker can change the memory/computation, gains additional (non-black-box) knowledge by interacting...... with the faulty device and then tries to break the security. Prior works show that generically approaching such problem is notoriously difficult. So, in this dissertation we attempt to solve an easier question, known as memory-tampering, where the attacker is allowed tamper only with the memory of the device...

    It is known that there is a high prevalence of certain anxiety disorders among schizophrenic patients, especially panic disorder and social phobia. However, the neural underpinnings of the comorbidity of such anxiety disorders and schizophrenia remain unclear. Our study aims to determine the neuroanatomical basis of the co-occurrence of schizophrenia with panic disorder and social phobia. Voxel-based morphometry was used in order to examine brain structure and to measure between-group differences, comparing magnetic resonance images of 20 anxious patients, 20 schizophrenic patients, 20 schizophrenic patients with comorbid anxiety, and 20 healthy control subjects. Compared to the schizophrenic patients, we observed smaller grey-matter volume (GMV) decreases in the dorsolateral prefrontal cortex and precentral gyrus in the schizophrenic-anxiety group. Additionally, the schizophrenic group showed significantly reduced GMV in the dorsolateral prefrontal cortex, precentral gyrus, orbitofrontal cortex, temporal gyrus and angular/inferior parietal gyrus when compared to the control group. Our findings suggest that the comorbidity of schizophrenia with panic disorder and social phobia might be characterized by specific neuroanatomical and clinical alterations that may be related to maladaptive emotion regulation related to anxiety. Even thought our findings need to be replicated, our study suggests that the identification of neural abnormalities involved in anxiety, schizophrenia and schizophrenia-anxiety may lead to an improved diagnosis and management of these conditions.

    2015-01-01

    This study assessed childhood trauma history, dissociative symptoms, and dissociative disorder comorbidity in patients with panic disorder (PD). A total of 92 psychotropic drug-naive patients with PD, recruited from outpatient clinics in the psychiatry department of a Turkish hospital, were involved in the study. Participants were assessed using the Structured Clinical Interview for DSM-IV Dissociative Disorders (SCID-D), Dissociation Questionnaire, Panic and Agoraphobia Scale, Panic Disorder Severity Scale, and Childhood Trauma Questionnaire. Of the patients with PD, 18 (19%) had a comorbid dissociative disorder diagnosis on screening with the SCID-D. The most prevalent disorders were dissociative disorder not otherwise specified, dissociative amnesia, and depersonalization disorders. Patients with a high degree of dissociation symptoms and dissociative disorder comorbidity had more severe PD than those without (p dissociation and PD. Among all of the subscales, the strongest relationship was with childhood emotional abuse. Logistic regression analysis showed that emotional abuse and severity of PD were independently associated with dissociative disorder. In our study, a significant proportion of the patients with PD had concurrent diagnoses of dissociative disorder. We conclude that the predominance of PD symptoms at admission should not lead the clinician to overlook the underlying dissociative process and associated traumatic experiences among these patients.

  16. Exploiting Hardware Vulnerabilities to Attack Embedded System Devices: a Survey of Potent Microarchitectural Attacks

    Directory of Open Access Journals (Sweden)

    Apostolos P. Fournaris

    2017-07-01

    Full Text Available Cyber-Physical system devices nowadays constitute a mixture of Information Technology (IT and Operational Technology (OT systems that are meant to operate harmonically under a security critical framework. As security IT countermeasures are gradually been installed in many embedded system nodes, thus securing them from many well-know cyber attacks there is a lurking danger that is still overlooked. Apart from the software vulnerabilities that typical malicious programs use, there are some very interesting hardware vulnerabilities that can be exploited in order to mount devastating software or hardware attacks (typically undetected by software countermeasures capable of fully compromising any embedded system device. Real-time microarchitecture attacks such as the cache side-channel attacks are such case but also the newly discovered Rowhammer fault injection attack that can be mounted even remotely to gain full access to a device DRAM (Dynamic Random Access Memory. Under the light of the above dangers that are focused on the device hardware structure, in this paper, an overview of this attack field is provided including attacks, threat directives and countermeasures. The goal of this paper is not to exhaustively overview attacks and countermeasures but rather to survey the various, possible, existing attack directions and highlight the security risks that they can pose to security critical embedded systems as well as indicate their strength on compromising the Quality of Service (QoS such systems are designed to provide.

  17. Carbon dioxide inhalation induces dose-dependent and age-related negative affectivity.

    Directory of Open Access Journals (Sweden)

    Eric J Griez

    Full Text Available BACKGROUND: Carbon dioxide inhalation is known to induce an emotion similar to spontaneous panic in Panic Disorder patients. The affective response to carbon dioxide in healthy subjects was not clearly characterized yet. METHODOLOGY/PRINCIPAL FINDINGS: Sixty-four healthy subjects underwent a double inhalation of four mixtures containing respectively 0, 9, 17.5 and 35% CO(2 in compressed air, following a double blind, cross-over, randomized design. Affective responses were assessed according to DSM IV criteria for panic, using an Electronic Visual Analogue Scale and the Panic Symptom List. It was demonstrated that carbon dioxide challenges induced a dose dependent negative affect (p<0.0001. This affect was semantically identical to the DSM IV definition of panic. Older individuals were subjectively less sensitive to Carbon Dioxide (p<0.05. CONCLUSIONS/SIGNIFICANCE: CO(2 induced affectivity may lay on a continuum with pathological panic attacks. Consistent with earlier suggestions that panic is a false biological alarm, the affective response to CO(2 may be part of a protective system triggered by suffocation and acute metabolic distress.

    We demonstrate the experimental feasibility of a Trojan-horse attack that remains nearly invisible to the single-photon detectors employed in practical quantum key distribution (QKD) systems, such as Clavis2 from ID Quantique. We perform a detailed numerical comparison of the attack performance against Scarani-Ac´ın-Ribordy-Gisin (SARG04) QKD protocol at 1924 nm versus that at 1536 nm. The attack strategy was proposed earlier but found to be unsuccessful at the latter wavelength, as reported in N. Jain et al., New J. Phys. 16, 123030 (2014). However at 1924 nm, we show experimentally that the noise response of the detectors to bright pulses is greatly reduced, and show by modeling that the same attack will succeed. The invisible nature of the attack poses a threat to the security of practical QKD if proper countermeasures are not adopted.

    Full Text Available Procura-se articular o que Freud denominou "mal-estar na civilização" às psicopatologias contemporâneas, examinando-se a relação da incidência do pânico com as modalidades subjetivas emergentes. Diante do deslocamento da ordem paterna como referencial central, o desamparo do sujeito contemporâneo tornou-se agudo. Na tentativa de proteção contra o desamparo, o sujeito pode fazer uso de modalidades subjetivas que privilegiam o masoquismo. O pânico seria efeito do desamparo na contemporaneidade, uma forma de padecimento em que está em jogo o masoquismo como figura da servidão.Pretends to articulate what Freud called "civilization and its discontents" to contemporary psychopathologies, examining the relationship between the incidence of panic symptoms and contemporary ways of subjectivity construction. In face of current displacement of paternal order as a central reference, the helplessness of the subject became severe, acute. To protect himself from a radical helplessness, masochist ways may be privileged. The panic is an effect a helplessness in contemporary society, a suffering form where masochism appears as a figure of servitude.

    Full Text Available Denial of service (DoS attack is an attempt of the attacker to disable victim's machine by depleting network or computing resources. If this attack is performed with more than one machine, it is called distributed denial of service (DDoS attack. Covert channels are those channels which are used for information transmission even though they are neither designed nor intended to transfer information at all. In this article, we investigated the possibility of using of DDoS attack for purposes of hiding data or concealing the existing covert channel. In addition, in this paper we analyzed the possibility of detection of such covert communication with the well-known statistical method. Also, we proposed the coordination mechanisms of the attack which may be used. A lot of research has been done in order to describe and prevent DDoS attacks, yet research on steganography on this field is still scarce.

Nuestro análisis ofrece evidencia clara de la hipótesis de histéresis, que parece estar causada por una tendencia estocástica común que impulsa a las series de desempleo regionales. Estos resultados están respaldados por los obtenidos de la estimación insesgada en la mediana del parámetro de persistencia, que arroja un valor unitario para el factor común, y en menor medida por la estimación de la vida media obtenida a partir de funciones impulso-respuesta, que arroja un valor de 12.5 para el caso de las perturbaciones que afectan a la tendencia común.

    Problematic Internet use is a worldwide social issue and it can be found in any age, social, educational, or economic range. In some countries like China and South Korea internet addiction (IA) is considered a public health condition and this governments support research, education and treatment. Internet addiction has been associated with others psychiatric disorders. Panic disorder (PD) and Obsessive Compulsive Disorder (OCD) are anxiety disorders that involve a lot of damages in patient's life. We report a treatment of a patient with Panic Disorder and Obsessive Compulsive Disorder and internet addition involving pharmacotherapy and Cognitive Behavioral Therapy (CBT). The Cognitive Behavioral Therapy was conducted 1 time per week during 10 weeks and results suggest that the treatment was an effective treatment for the anxiety and for the internet addiction.

    Patients' problematic substance use prevalence and effects were explored in relation to internet-based cognitive behavioral therapy (ICBT) outcomes for depression, panic disorder and social anxiety disorder. At baseline and treatment conclusion, 1601 ICBT patients were assessed with self-rated measures for alcohol and drug use (AUDIT/DUDIT), depressive symptoms (MADRS-S), panic disorder symptoms (PDSS-SR) and social anxiety symptoms (LSAS-SR). Problematic substance use (AUDIT ≥ 8 for men, ≥ 6 for women; DUDIT ≥ 1) occurred among 32.4% of the patients; 24.1% only alcohol, 4.6% only drugs, and 3.7% combined alcohol and drug use. Hazardous alcohol use and probable alcohol dependence negatively affected panic disorder outcomes, and hazardous drug use led to worse social anxiety outcomes. Depression outcomes were not affected by substance use. Treatment adherence was negatively affected by problematic drug use among men and 25-34 year olds; combined substance use negatively affected adherence for women and 35-64 year olds. Problematic substance use does not preclude ICBT treatment but can worsen outcomes, particularly problematic alcohol use for panic disorder patients and hazardous drug use for social anxiety patients. ICBT clinicians should exercise particular caution when treating men and younger patients with problematic drug use, and women or older patients with combined substance use.

    2010-11-01

    Full Text Available Abstract Background Cognitive behavioral therapy (CBT represents a learning process leading to symptom relief and resulting in long-term changes in behavior. CBT for panic disorder is based on exposure and exposure-based processes can be studied in the laboratory as extinction of experimentally acquired fear responses. We have recently demonstrated that the ability to extinguish learned fear responses is associated with a functional genetic polymorphism (COMTval158met in the COMT gene and this study was aimed at transferring the experimental results on the COMTval158met polymorphism on extinction into a clinical setting. Methods We tested a possible effect of the COMTval158met polymorphism on the efficacy of CBT, in particular exposure-based treatment modules, in a sample of 69 panic disorder patients. Results We present evidence that panic patients with the COMTval158met met/met genotype may profit less from (exposure-based CBT treatment methods as compared to patients carrying at least one val-allele. No association was found with the 5-HTTLPR/rs25531 genotypes which is presented as additional material. Conclusions We were thus able to transfer findings on the effect of the COMTval158met polymorphism from an experimental extinction study obtained using healthy subjects to a clinical setting. Furthermore patients carrying a COMT val-allele tend to report more anxiety and more depression symptoms as compared to those with the met/met genotype. Limitations of the study as well as possible clinical implications are discussed.

    Welzijnsorganisaties, onderzoekinstellingen, overheidsinstellingen en woningcorporaties zijn alle potentiële partners in stedelijke herstructureringsprogramma’s. Het combineren van de belangen van deze organisaties vormt een interessante managementuitdaging. Ook is het een uitdaging om een informatiesysteem te ontwikkelen dat tegemoet komt aan de informatiebehoefte van alle partners, zowel de afzonderlijke organisaties, als het collectief. Dit artikel zal deze uitdaging van informatiemanagement bespreken, door een case study naar cooperative knowledge production te presenteren. De case study heeft betrekking op het Rotterdamse stedelijk investeringssprogramma “Pact op Zuid”, een programma waarin tussen 2006 en 2016 1.5 miljard euro wordt geïnvesteerd in stedelijk gebied met 190.000 inwoners. Dit artikel geeft allereerst inzicht in literatuur over innovatieconfiguraties en lerende netwerken, concepten die belangrijk zijn om de complexiteit van stedelijke renovatie en cooperative knowledge production te begrijpen. Het bespreekt eveneens hoe cooperative knowledge production binnen Pact op Zuid plaatsvond.

  20. Study on multiple-hops performance of MOOC sequences-based optical labels for OPS networks

    Zhang, Chongfu; Qiu, Kun; Ma, Chunli

    2009-11-01

    In this paper, we utilize a new study method that is under independent case of multiple optical orthogonal codes to derive the probability function of MOOCS-OPS networks, discuss the performance characteristics for a variety of parameters, and compare some characteristics of the system employed by single optical orthogonal code or multiple optical orthogonal codes sequences-based optical labels. The performance of the system is also calculated, and our results verify that the method is effective. Additionally it is found that performance of MOOCS-OPS networks would, negatively, be worsened, compared with single optical orthogonal code-based optical label for optical packet switching (SOOC-OPS); however, MOOCS-OPS networks can greatly enlarge the scalability of optical packet switching networks.

The basic types of DDoS attacks and their impact on the protected network are presented here. Furthermore, we present basic detection and defense techniques thanks to which it is possible to increase resistance of the protected network or device against DDoS attacks. Moreover, we tested the ability of current commercial Intrusion Prevention Systems (IPS, especially Radware DefensePro 6.10.00 product against the most common types of DDoS attacks. We create five scenarios that are varied in type and strength of the DDoS attacks. The attacks intensity was much greater than the normal intensity of the current DDoS attacks.

    A 36-year-old man with comorbid panic disorder with agoraphobia, major depression, and histrionic personality disorder since age 21 was resistant to combined drug and psychotherapy treatment. His conditions had progressively worsened with time, causing him to withdraw socially and to simultaneously require continuous physical restraint, which further worsened his functioning. He spent almost 3 consecutive years in restraint, until he consented to receive bilateral ECT treatment. He improved after 13 sessions in all areas (social and role functioning, and panic, depressive, and histrionic symptoms) and is well 3 months later with a lithium-atypical antipsychotic combination.

    The development of voice activated panic button application aims to design faster early notification of hazardous condition in community to the nearest police by using speech as the detector where the current application still applies touch-combination on screen and use coordination of orders from control center then the early notification still takes longer time. The method used in this research was by using voice recognition as the user voice detection and haversine formula for the comparison of closest distance between the user and the police. This research was equipped with auto sms, which sent notification to the victim’s relatives, that was also integrated with Google Maps application (GMaps) as the map to the victim’s location. The results show that voice registration on the application reaches 100%, incident detection using speech recognition while the application is running is 94.67% in average, and the auto sms to the victim relatives reaches 100%.

    In recent years, the Trojan Horse Method (THM) has been used to investigate the low-energy cross sections of proton-induced reactions on A = 17 and A = 18 oxygen isotopes, overcoming extrapolation procedures and enhancement effects due to electron screening. In particular, the strengths of the 20 keV and 65 keV resonances in the {sup 18}O(p, {alpha}){sup 15}N and {sup 17}O(p, {alpha}){sup 14}N reactions, respectively, have been extracted, as well as the contribution of the tail of the broad 656 keV resonance in the {sup 18}O(p, {alpha}){sup 15}N reaction inside the Gamow window. The strength of the 65 keV resonance in the {sup 17}O(p, {alpha}){sup 14}N reaction, measured by means of the THM, has been used to renormalize the corresponding resonance strength in the {sup 17}O + p radiative capture channel. As a result, more accurate reaction rates for the {sup 18}O(p, {alpha}){sup 15}N, {sup 17}O(p, {alpha}){sup 14}N, and {sup 17}O(p, {gamma}){sup 18}F processes have been deduced, devoid of systematic errors due to extrapolation or the electron screening effect. Such rates have been introduced into state-of-the-art red giant branch and asymptotic giant branch (AGB) models for proton-capture nucleosynthesis coupled with extra-mixing episodes. The predicted abundances have been compared with isotopic compositions provided by geochemical analysis of presolar grains. As a result, an improved agreement is found between the models and the isotopic mix of oxide grains of AGB origins, whose composition is the signature of low-temperature proton-capture nucleosynthesis. The low {sup 14}N/{sup 15}N found in SiC grains cannot be explained by the revised nuclear reaction rates and remains a serious problem that has not been satisfactorily addressed.

    Full Text Available A great proportion of essential services are moving into internet space making the threat of DoS attacks even more actual. To estimate the real risk of some kind of denial of service (DoS attack in real world is difficult, but mathematical and software models make this task easier. In this paper we overview the ways of implementing DoS attack models and offer a stochastic model of SYN flooding attack. It allows evaluating the potential threat of SYN flooding attacks, taking into account both the legitimate system flow as well as the possible attack power. At the same time we can assess the effect of such parameters as buffer capacity, open connection storage in the buffer or filte­ring efficiency on the success of different SYN flooding attacks. This model can be used for other type of memory depletion denial of service attacks.Article in Lithuanian

    Full Text Available INTRODUCTION: Respiratory changes are associated with anxiety disorders, particularly panic disorder (PD. The stimulation of respiration in PD patients during panic attacks is well documented in the literature, and a number of abnormalities in respiration, such as enhanced CO2 sensitivity, have been detected in PD patients. Investigators hypothesized that there is a fundamental abnormality in the physiological mechanisms that control breathing in PD. METHODS: The authors searched for articles regarding the connection between the respiratory system and PD, more specifically papers on respiratory challenges, respiratory subtype, and current mechanistic concepts. CONCLUSIONS: Recent evidences support the presence of subclinical changes in respiration and other functions related to body homeostasis in PD patients. The fear network, comprising the hippocampus, medial prefrontal cortex, amygdala and its brainstem projections, may be abnormally sensitive in PD patients, and respiratory stimulants like CO2 may trigger panic attacks. Studies indicate that PD patients with dominant respiratory symptoms are particularly sensitive to respiratory tests compared to those who do not manifest dominant respiratory symptoms, representing a distinct subtype. The evidence of changes in several neurochemical systems might be the expression of the complex interaction among brain circuitsINTRODUÇÃO: As anormalidades respiratórias estão associadas a transtornos de ansiedade, especialmente ao transtorno do pânico (TP. A estimulação respiratória em pacientes com TP durante os ataques de pânico está bem documentada na literatura, e vários problemas respiratórios como uma elevada sensibilidade ao CO2 foram detectados em pacientes com TP.

    The Affordable Care Act paves the way for groups to develop innovative, affordable health insurance and care options known as Consumer Operated and Oriented Plans (CO-OPs). These CO-OPs will be nonprofit, consumer-controlled entities that are designed to serve individuals and small businesses, especially in noncompetitive markets. The CO-OP provision was included in the Affordable Care Act to address the lack of affordable health plan alternatives in many state and regional markets and to counter a trend toward market concentration. Despite their promise, CO-OPs face a number of business challenges that go beyond typical start-up hurdles. This issue brief lays out a number of innovative strategies CO-OP organizers are developing to increase the odds of long-term sustainability and economic success. These strategies--aimed at building market share, creating integrated provider networks, and achieving cost savings through payment reform--could establish CO-OPs as a viable new entrant in the health care field.

    Full Text Available Introduction: The objective of this study was to investigate with the help of a computerized simulation model whether the treatment of an acute asthma attack can be individualized based on the severity of the attack and the characteristics of the patient. Material and Method: A stochastic lung model was used to simulate the deposition of 1 nm - 10 μm particles during a mild and a moderate asthma attack. Breathing parameters were varied to maximize deposition, and simulation results were compared with those obtained in the case of a severe asthma attack. In order to investigate the effect of height on the deposition of inhaled particles, another series of simulations was carried out with identical breathing parameters, comparing patient heights of 155 cm, 175 cm and 195 cm. Results: The optimization process yielded an increase in the maximum deposition values of around 6-7% for each type of investigated asthma attack, and the difference between attacks of different degree of severity was around 5% for both the initial and the optimized values, a higher degree of obstruction increasing the amount of deposited particles. Conclusions: Our results suggest that the individualization of asthma attack treatment cannot be based on particles of different size, as the highest deposited fraction in all three types of attacks can be obtained using 0.01 μm particles. The use of a specific set of breathing parameters yields a difference between a mild and a moderate, as well as a moderate and a severe asthma attack of around 5%.

    Combined administration of ornithine and phenylacetate (OP) is proposed as a novel treatment of hyperammonemia and hepatic encephalopathy. Ornithine is believed to increase ammonia fixation into glutamine in muscle tissue and glutamine is subsequently thought to react with phenylacetate forming......, skeletal muscle, liver and kidney. In BDL rats, OP treatment reduced arterial ammonia concentration and increased that of glutamine 30min after the treatment but not after 15h. OP treatment did not increase (15)N labeling in glutamine from [2,5-(15)N]ornithine and (15)NH(4)(+) in skeletal muscle or liver....... However, the extent of glutamine labeling from [2,5-(15)N]ornithine or (15)NH(4)(+) was similar in arterial blood and liver and higher than that in skeletal muscle. These findings suggest that the effect of OP was related to hepatic metabolism of ornithine. PAGN could not be detected in urine or blood...

    Full Text Available Co-op advertising is an interactive relationship between manufacturer and retailer(s supply chain and makes up the majority of marketing budget in many product lines for manufacturers and retailers. This paper considers pricing and co-op advertising decisions in two-stage supply chain and develops a monopolistic retailer and duopolistic retailer's model. In these models, the manufacturer and the retailers play the Nash, Manufacturer-Stackelberg and cooperative game to make optimal pricing and co-op advertising decisions. A bargaining model is utilized for determine the best pricing and co-op advertising scheme for achieving full coordination in the supply chain.

    To determine the brain function and structure in patinets with first-episode panic disorder (PD). All subjects (24 PD patients and 24 healthy subjects) received MRI scan and emotional counting Stroop task during the functional magnetic resonance imaging. Blood oxygenation level dependent functional magnetic resonance imaging and voxel-based morphometric technology were used to detect the gray matter volume. Compared with the healthy controls, left thalamus, left medial frontal gyrus, left anterior cingulate gyrus, left inferior frontal gyrus, left insula (panic-related words vs. neutral words) lacked activation in PD patients, but the over-activation were found in right brain stem, right occipital lobe/lingual gyrus in PD patients. Compared with the healthy controls, the gray matter volume in the PD patients significantly decreased in the left superior temporal gyrus, right medial frontal gyrus, left medial occipital gyrus, dorsomedial nucleus of left thalamus and right anterior cingulate gyrus. There was no significantly increased gray matter volume in any brain area in PD patients. PD patients have selective attentional bias in processing threatening information due to the depression and weakening of the frontal cingulated gyrus.

    Full Text Available PURPOSE: Patients' problematic substance use prevalence and effects were explored in relation to internet-based cognitive behavioral therapy (ICBT outcomes for depression, panic disorder and social anxiety disorder. METHODS: At baseline and treatment conclusion, 1601 ICBT patients were assessed with self-rated measures for alcohol and drug use (AUDIT/DUDIT, depressive symptoms (MADRS-S, panic disorder symptoms (PDSS-SR and social anxiety symptoms (LSAS-SR. RESULTS: Problematic substance use (AUDIT ≥ 8 for men, ≥ 6 for women; DUDIT ≥ 1 occurred among 32.4% of the patients; 24.1% only alcohol, 4.6% only drugs, and 3.7% combined alcohol and drug use. Hazardous alcohol use and probable alcohol dependence negatively affected panic disorder outcomes, and hazardous drug use led to worse social anxiety outcomes. Depression outcomes were not affected by substance use. Treatment adherence was negatively affected by problematic drug use among men and 25-34 year olds; combined substance use negatively affected adherence for women and 35-64 year olds. CONCLUSION: Problematic substance use does not preclude ICBT treatment but can worsen outcomes, particularly problematic alcohol use for panic disorder patients and hazardous drug use for social anxiety patients. ICBT clinicians should exercise particular caution when treating men and younger patients with problematic drug use, and women or older patients with combined substance use.

  19. WILD PIG ATTACKS ON HUMANS

    2013-04-12

    Attacks on humans by wild pigs (Sus scrofa) have been documented since ancient times. However, studies characterizing these incidents are lacking. In an effort to better understand this phenomenon, information was collected from 412 wild pig attacks on humans. Similar to studies of large predator attacks on humans, data came from a variety of sources. The various attacks compiled occurred in seven zoogeographic realms. Most attacks occurred within the species native range, and specifically in rural areas. The occurrence was highest during the winter months and daylight hours. Most happened under non-hunting circumstances and appeared to be unprovoked. Wounded animals were the chief cause of these attacks in hunting situations. The animals involved were typically solitary, male and large in size. The fate of the wild pigs involved in these attacks varied depending upon the circumstances, however, most escaped uninjured. Most human victims were adult males traveling on foot and alone. The most frequent outcome for these victims was physical contact/mauling. The severity of resulting injuries ranged from minor to fatal. Most of the mauled victims had injuries to only one part of their bodies, with legs/feet being the most frequent body part injured. Injuries were primarily in the form of lacerations and punctures. Fatalities were typically due to blood loss. In some cases, serious infections or toxemia resulted from the injuries. Other species (i.e., pets and livestock) were also accompanying some of the humans during these attacks. The fates of these animals varied from escaping uninjured to being killed. Frequency data on both non-hunting and hunting incidents of wild pig attacks on humans at the Savannah River Site, South Carolina, showed quantitatively that such incidents are rare.
