RESUMO

BACKGROUND In the field of living donor liver transplantation (LDLT), it is important to ensure donor's psychological well-being. We report on clinical features and long-term outcomes of LDLT donors who developed psychiatric disorders after their donor operations. Additionally, we compare patient backgrounds, as well as surgical and perioperative aspects between LDLT donors with and without postoperative psychiatric complications. MATERIAL AND METHODS Between November 1998 and March 2018, we identified 254 LDLT donors at our hospital. Among these, we investigated those who had newly developed psychiatric complications and required psychiatric treatment after donor operation. RESULTS The median duration of follow-up was 4 years. Sixty-five donors were lost to follow-up. Eight donors (3.1%) developed postoperative psychiatric complications, including major depressive disorder in 4, panic disorder in 2, conversion disorder and panic disorder in 1, and adjustment disorder in 1. The median duration from donor surgery to psychiatric diagnosis was 104.5 days (range, 12 to 657 days) and the median treatment duration was 18 months (range, 3 to 168 months). Of those, 3 donors required psychiatric treatment over 10 years, and 4 donors remained under treatment. The duration of hospital stay after donor operation was significantly longer and perioperative complications with Clavien classification greater than grade IIIa were more frequent in donors with psychiatric complications than in those without psychiatric complications (P=0.02 and P=0.006, respectively). CONCLUSIONS Accurate diagnosis and appropriate treatment for psychiatric disorders by psychiatrists and psychologists are important during LDLT donor follow-up. Minimization of physiological complications might be important to prevent postoperative psychiatric complications in LDLT donors.

RESUMO

Patients with progressive cognitive decline mostly suffer from degenerative disease and carry a relatively poor prognosis. But small groups among these patients have a potentially treatable cause of illness and therefore every patient with dementia needs to be considered treatable unless proved otherwise. This group can be identified only by high degree of suspicion based on clinical clues. We have evaluated the validity of some simple clinical clues which we noticed in our patients with immune mediated dementias. The Panic score, Epsworth sleepiness score, catatonic symptoms and history of seizures were compared between 23 and 11 patients with serologically confirmed anti-NMDA antibody and anti-VGKC antibody associated encephalitis respectively. They were compared with 20 patients with probable behavioral variant of Frontotemporal dementia (bvFTD) and 20 patients with probable Alzheimer's disease (AD). Chi-square test was used to compare across the groups and there was significant difference (P < 0.05) across the 4 groups comprising anti NMDA encephalitis, anti VGKC encephalitis, FTD and AD among the four variables (Panic scores, Catatonic symptoms, Epsworth sleepiness score and seizures) studied. Our study revealed that panic and sleepiness is highly significant when tested across all groups and catatonia showed a trend towards NMDA and when compared with degenerative dementia versus immune mediated syndromes all the 4 parameters were highly significant This simple bedside TRIAD of panic, sleepiness with either of catatonia or seizures if found in patients it is appropriate to order antibody assessment before anything else is planned. This needs to be evaluated in a larger sample.

RESUMO

O presente ensaio tem como objetivo apresentar reflexões sobre o processo diagnóstico no campo dos transtornos mentais com manifestações clínicas, especificamente, o transtorno do pânico (TP), assim como seu impacto no sistema de saúde e na rotina dos serviços de emergência, além de apontar diretrizes para o acolhimento, manejo e encaminhamento dos usuários que apresentam esse sofrimento psíquico-emocional. A dor torácica é um dos sintomas mais comuns nos serviços de emergência médica de atendimento primário. Por ser um sintoma presente tanto no transtorno do pânico quanto na isquemia miocárdica na doença arterial coronariana (DAC), muitos indivíduos acometidos por TP acreditam estar na iminência de um problema grave de saúde, como por exemplo, o infarto agudo do miocárdio. Temos no caso do TP um exemplo da ausência de fronteiras entre o somático e o psíquico, pois a mistura dos sintomas físicos e emocionais podem confundir o processo diagnóstico. O profissional atua em um contexto desafiador, pois se vê em meio a demandas que, muitas vezes, incluem questões de outra ordem além da orgânica. É fundamental que apure sua escuta para realizar um diagnóstico diferencial e o encaminhamento adequado, devendo ter cuidado ao se comunicar com o paciente que busca atendimento


This essay presents some reflections about the diagnostic process in the field of mental disorders with clinical symptoms, specifically, Panic Disorder (PD), and their impact on the Health System and the routine of the emergency services. It also points out some guidelines to receipt, management and referral of users who present this psychic-emotional suffering. Chest pain is one of the most common symptoms in the primary care emergency medical services. As a symptom that is present in both panic disorder and myocardial ischemia in coronary artery disease (CAD), many individuals affected by PD believe they are on the verge of a serious health problem, such as acute myocardial infarction. The case of PD is an example of the blurring of borders between the somatic and the psychic, as a mixture of physical and emotional symptoms can lead to confusion in the diagnostic process. Professionals act in a challenging context, with many demands being placed on them, which often include issues other than organic ones. It is essential that these professionals listen carefully, in order to make a differential diagnosis and proper referral, paying close attention when communicating with the patient who is seeking care

RESUMO

BACKGROUND: Ganglioglioma is a rare, benign, intraaxial glioneuronal tumor but a relatively common cause of pharmacoresistant temporal lobe epilepsy (TLE). Given its often nonspecific neuropsychiatric manifestations and frequently negative electroencephalographic workup, TLE can be easily misdiagnosed as a psychiatric disorder, particularly panic attacks. CASE DESCRIPTION: We present a case of a 17-year-old boy who was found to have lesional TLE secondary to a left temporal ganglioglioma, 5 years after having been misdiagnosed with panic disorder and having undergone ineffective and unnecessary psychotherapy. He was successfully cured by surgery. Although a few similar cases of TLE masquerading as a panic disorder have been previously reported in the literature, this is the youngest and only pediatric patient described to date. CONCLUSION: This report underscores the challenges in making an accurate clinical diagnosis of TLE and the importance of timely brain imaging whenever an atypical or medically refractory panic disorder is encountered.

RESUMO

Introduction Mitochondriopathies are pathologies of cell organelles, which are essential for the formation of adenosine triphosphate (ATP), which is responsible for cellular energy stock. When mitochondrial mutations occur, symptoms arise frequently in those organs that rely on a continuous energy supply, such as the nervous system. Although psychiatric illness is increasingly prevalent in patients with mitochondrial disease, less attention has been paid to its psychiatric presentations. Case Report We describe a case of a 21-year-old woman who presented in our outpatient department with panic attacks and depression. The patient experienced major side effects after low-dose sertraline therapy. Conclusion Mitochondriopathies belong to the class of rare illnesses in psychiatry; nevertheless, they require adaptations of psychopharmacological therapy. Psychotropic drugs are potential respiratory chain inhibitors and could lead to distinct side effects.

RESUMO

OBJECTIVE: The current study examined the relationship between cigarette smoking (daily) and risk of onset and persistence of panic attacks over a 10-year period among adults in mid-adulthood in the United States and whether quitting smoking reduced the risk for panic attacks. METHOD: Data were drawn from the Midlife Development in the United States Survey (N = 2,101), a nationally representative sample of adults aged 25 to 74 years at baseline (wave 1, 1994-1995) who were followed up 10 years later at wave 2 (2004-2006). Psychiatric diagnoses were based on the Composite International Diagnostic Interview Short-Form (CIDI-SF [based on DSM-III-R criteria]) scales. Logistic regressions were used to evaluate the associations between smoking status and the onset and persistence of panic attack after controlling for demographic characteristics and substance use problems. RESULTS: Daily smoking in 1994 (OR = 1.9 [95% CI, 1.1-3.3]) and persistent daily smoking in 1994 and 2005 (OR = 2.6 [95% CI, 1.4-4.8]) were associated with a significantly increased likelihood of panic attacks in 2005. Moreover, smoking abstinence significantly reduced the risk of new-onset panic attacks (OR = 0.6 [95% CI, 0.4-0.97]) and persistence of panic attacks (OR = 0.2 [95% CI, 0.1-0.5]). CONCLUSIONS: The present data provide novel evidence that smoking is associated with an increased risk of panic attacks and that quitting smoking helps reduce such risk.

RESUMO

BACKGROUND: Distress intolerance is linked to the maintenance of panic disorder and cigarette smoking, and may underlie both problems. METHOD: Smokers (n = 54; 40.7% panic disorder) were recruited for an experimental study; half were randomly assigned to 12-hour nicotine deprivation and half smoked as usual. The current investigation consisted of secondary, exploratory analyses from this larger experimental study. Four distress intolerance indices were examined as predictors of anxious responding to an emotional elicitation task (10% carbon dioxide (CO2)-enriched air challenge); anxious responding was in turn examined as a predictor of post-challenge panic and nicotine withdrawal symptoms. RESULTS: The Distress Tolerance Scale (DTS) was significantly negatively associated with anxious responding to the challenge (ß = -0.41, p = 0.017). The DTS was negatively associated with post-challenge increases nicotine withdrawal symptoms indirectly through the effect of anxious responding to the challenge (b = -0.485, CI95% (-1.095, -0.033)). This same indirect effect was found for post-challenge severity of panic symptoms (b = -0.515, CI95% (-0.888, -0.208)). The DTS was directly predictive of post-challenge increases nicotine withdrawal symptoms, in the opposite direction (ß = 0.37, p = 0.009), but not panic symptom severity. CONCLUSIONS: Anxious responding in response to stressful experiences may explain the impact of perceived distress intolerance on panic and nicotine withdrawal symptom expression.

RESUMO

OBJECTIVE: This study's objective was to promote the transcultural adaptation of the Patient Health Questionnaire-Panic Disorder Module (PHQ-PD) for Brazilian Portuguese and to evaluate the discriminative validity of this scale in detecting PD among cancer patients. METHODS: Adult cancer outpatients (n=400) from a specialized cancer hospital (61.50% female; 68.40% married; 56% incomplete elementary education or elementary school as the highest educational level) were assessed with the Structured Clinical Interview for DSM-IV and PHQ-PD. Using receiver operating characteristic (ROC) analyses, we determined the sensitivity and specificity values for the original PD algorithm and the PD screening. RESULTS: The prevalence of PD in cancer patients (8.75%) was higher than the prevalence of PD for the general population. The original PD algorithm demonstrated an accuracy of 0.66, sensitivity of 0.31 and specificity of 0.94. The PD screening question in the PHQ-PD had a sensitivity of 0.66 and a specificity of 0.75 (accuracy=0.80). CONCLUSION: PD screening questions in the PHQ-PD may be useful for identifying cancer patients with PD because of the high prevalence of PD in this population and because the questionnaire's sensitivity is greater than that of the original PD algorithm. Nevertheless, researchers and clinical practitioners should consider the original PD algorithm (five items) in the PHQ-PD when they investigate PD in patients because of the algorithm's high specificity. Individuals who are found to be positive for PD on screening should be referred for assessment and a thorough psychiatric interview that focuses on the differential diagnosis of an anxiety disorder relating to cancer.

RESUMO

INTRODUCTION: There are limited evidences reported of temporal lobe epilepsy associated with active cysticercosis in cystic stage. The objective is to present the correlation between active cysticercosis in topographical zones associated with temporal lobe epilepsy, with neuropsychiatric manifestations and pattern of secondarily generalized partial seizures. CASE REPORTS: Two cases of adult patients with neuropsychiatric manifestations of one year evolution, refractory to antipsychotic drug treatment, and who subsequently appear late onset partial-secondarily generalized seizures. Cysticercosis active presence in the temporal lobe in one patient, and the insula in the other, is identified. A better clinical control after albendazol treatment and subsequently anticonvulsant therapy only remained to evaluate pertinence of pharmacological withdrawal criteria. CONCLUSIONS: Active neurocysticercosis, may be the cause of acquired neuropsychiatric disorders and temporal lobe epilepsy of late onset when the topography is in the mesolimbic circuit. Early etiologic diagnosis and appropriate treatment allows adequate control of their symptoms and potentially final cure.


TITLE: Epilepsia del lobulo temporal y neurocisticercosis activa: dos casos representativos.Introduccion. Existen pocas evidencias notificadas de casos de epilepsia del lobulo temporal asociadas a cisticercosis activa en su fase quistica. El objetivo es presentar la correlacion entre cisticercosis activa en zonas topograficas asociadas a epilepsia del lobulo temporal, con las manifestaciones neuropsiquiatricas y el patron de crisis parciales secundariamente generalizadas. Casos clinicos. Dos casos de pacientes adultos con manifestaciones neuropsiquiatricas de un año de evolucion, refractarios a tratamiento farmacologico antipsicotico, y en quienes posteriormente aparecen crisis convulsivas parciales secundariamente generalizadas de inicio tardio. Se identifica la presencia de cisticercosis activa en el lobulo temporal en un paciente, y en la insula, en el otro. Buen control clinico posterior al tratamiento con albendazol, pero se mantiene el mismo tratamiento anticonvulsionante para considerar la pertinencia de su retirada farmacologica. Conclusiones. La neurocisticercosis activa puede ser causa de trastornos neuropsiquiatricos adquiridos y de epilepsia del lobulo temporal de inicio tardio cuando su topografia se encuentra en el circuito mesolimbico. El diagnostico etiologico oportuno y el tratamiento apropiado permiten el control adecuado de su sintomatologia y, potencialmente, su curacion definitiva.

RESUMO

Introduction: The study of the association between specific characteristics of family environments and different types of psychopathology may contribute to our understanding of these complex disorders and ultimately inform therapeutics. Objective: To compare the family characteristics of four groups: typically developing children; children with anxiety disorders only; children with externalizing disorders only; and children with both anxiety and externalizing disorders. Methods: This study enrolled 115 individuals from the community. Child psychiatrists made psychiatric diagnoses using a structured clinical interview. The Family Environment scale was used to evaluate six domains of family function. Results: The group with both anxiety and externalizing disorders had higher levels of conflict in family environment and lower levels of organization when compared with typically developing children. In addition, internalizing and externalizing symptoms were positively associated with conflict and negatively with organization. Maternal depressive and anxious symptoms were also associated with higher conflict and lower organization scores. Conclusion: An important between-group difference in comorbid cases of anxiety and behavioral disorders suggests that children with this comorbidity are potential candidates for family interventions to address family conflicts and organizational aspects (AU)


Introdução: O estudo da relação entre características específicas do ambiente familiar e os diferentes tipos de psicopatologias pode contribuir para o nosso entendimento desses complexos transtornos e possivelmente gerar informações para seu tratamento. Objetivo: Comparar as características familiares de quatro grupos: Crianças com desenvolvimento típico; crianças com transtornos de ansiedade apenas; crianças com transtornos de externalização apenas; e crianças com transtornos de ansiedade e de externalização. Métodos: Cento e quinze indivíduos foram recrutados na comunidade. Psiquiatras pediátricos usaram uma entrevista clínica estruturada para estabelecer os diagnósticos psiquiátricos. A Escala do Ambiente Familiar (Family Environment) foi usada para avaliar os seis domínios de funcionamento da família. Resultados: O grupo que apresentava tanto transtornos de ansiedade quanto de externalização apresentou níveis mais altos de conflito e níveis mais baixos de organização quando comparados com as crianças com desenvolvimento típico. Além disso, os sintomas de externalização e internalização estavam positivamente relacionados a conflitos e negativamente a organização. Sintomas depressivos e de ansiedade da mãe também se mostraram relacionados a resultados mais altos para conflito e mais baixos para organização. Conclusão: Uma importante diferença entre grupos em casos de comorbidades de transtornos de ansiedade e de comportamento sugerem que as crianças com esta comorbidades são candidatos em potencial para intervenções familiares que abordem conflitos familiares e aspectos organizacionais (AU)

RESUMO

Panic disorder is twice a common in women than in men. In women, susceptibility to panic increases during the late luteal (premenstrual) phase of the menstrual cycle, when progesterone secretion is in rapid decline. This article considers the evidence for the midbrain periaqueductal grey (PAG) as a locus for panic and for the use of PAG stimulation as an animal model of panic in both sexes. We show in females how a rapid fall in progesterone secretion, such as occurs during the late dioestrus phase of the ovarian cycle in rats (similar to the late luteal phase in women), triggers a neuronal withdrawal response during which the excitability of the midbrain panic circuitry increases as a result of upregulation of extrasynaptic GABAA receptors on inhibitory interneurones in the PAG. The withdrawal effect is due not to the native hormone but to its neuroactive metabolite allopregnanolone. Differences in the kinetics of allopregnanolone metabolism may contribute to individual differences in susceptibility to panic in women.

RESUMO

Patients undergoing a panic attack (PA) or a hyperventilation attack (HVA) are sometimes admitted to emergency departments (EDs). Reduced serotonin level is known as one of the causes of PA and HVA. Serotonin is synthesized from tryptophan. For the synthesis of serotonin, vitamin B6 (Vit B6) and iron play important roles as cofactors. To clarify the pathophysiology of PA and HVA, we investigated the serum levels of vitamins B2, B6, and B12 and iron in patients with PA or HVA attending an ED. We measured each parameter in 21 PA or HVA patients and compared the values with those from 20 volunteers. We found that both Vit B6 and iron levels were significantly lower in the PA/HVA group than in the volunteer group. There was no significant difference in the serum levels of vitamins B2 or B12. These results suggest that low serum concentrations of Vit B6 and iron are involved in PA and HVA. Further studies are needed to clarify the mechanisms involved in such differences.

RESUMO

This is a complex case of post-traumatic stress disorder (PTSD) with comorbid panic disorder occurring in a woman in her mid-60s, with a family history of neurotic illness. PTSD arose in the context of treatment for terminal lung cancer. This patient who had been close to her father watched him die of cancer, when he was about her age. Her diagnosis and treatment prompted traumatic recollections of her father's illness and death that resulted in her voluntary withdrawal from cancer treatment. The goals of treatment were to promptly reduce anxiety, minimise use of sedating pharmacotherapy, promote lucidity and prolong anxiety-free state thereby allowing time for important family interactions. Prompt, sustained relief of severe anxiety was necessary to achieve comfort at the end of life. Skilled additions of psychological therapies (eye movement desensitisation reprocessing, clinical hypnosis and breathing exercises) with combined pharmacotherapy (mirtazepine and quetiapine) led to control of anxiety and reduction of post-traumatic stress.

RESUMO

The hypothalamus is a forebrain structure critically involved in the organization of defensive responses to aversive stimuli. Gamma-aminobutyric acid (GABA)ergic 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.

RESUMO

Brain imaging studies suggest that panic disorder (PD) is mediated by several brain regions, including the anterior cingulate cortex (ACC). In the present report we describe a patient who experienced a panic attack during awake surgery (case 1) and another patient who developed PD after surgery and radiotherapy (case 2). In case 1, the patient experienced repeated panic attacks when the tumor at the upper border of right dorsal ACC was removed during awake surgery. In case 2, the patient developed PD at six months after surgery and Cyberknife radiotherapy. MRI examination revealed that the dorsal ACC size was reduced at six months after surgery and that the dorsal ACC was absent at two years after surgery, possibly due to radiotherapy-induced damage by radiotherapy. Profile of mood states (POMS) testing characterized the presence of tension-anxiety as the common abnormal symptom in cases 1 and 2. In conclusion, these results suggest that damage to the right dorsal ACC can induce PD and that this structure likely plays a pathophysiologic role in PD.
