Emetofobia: revisão crítica sobre um transtorno pouco estudado

INTRODUÇÃO: A emetofobia ou fobia de vômitos - que inclui o medo excessivo de vomitar ou de ver outras pessoas vomitando e pode ser desencadeado por estímulos internos e externos - é um transtorno mental complexo e pouco conhecido. OBJETIVO: Este estudo teve como objetivo levantar os conhecimentos disponíveis sobre diversos aspectos do quadro. MÉTODO: Revisão convencional da literatura dos últimos 30 anos utilizando como estratégia de busca as seguintes palavras-chave: emetofobia, emetofóbico, medo de vomitar, fobia de vomitar efobia de vômito. Foram incluídos artigos sobre epidemiologia, fenomenologia, diagnóstico diferencial e tratamento da emetofobia, assim como artigos referidos nestes. RESULTADOS: Não há dados de prevalência na população geral e pouco se sabe sobre a etiologia da emetofobia. A maioria dos estudos aponta predominância no sexo feminino, início precoce e curso crônico. Os comportamentos de esquiva podem impactar negativamente a vida ocupacional, social e familiar. Os principais diagnósticos diferenciais são: transtorno de pânico com agorafobia, fobia social, anorexia nervosa e transtorno obsessivo-compulsivo. Estudos de tratamento se resumem a relatos de casos e não há ensaios clínicos controlados, mas intervenções cognitivo-comportamentais parecem ser promissoras. CONCLUSÃO: Mais estudos são necessários para melhor compreensão sobre a epidemiologia, o quadro clínico, a etiologia, a classificação e o tratamento da emetofobia.

Toothache referred from auriculotemporal neuralgia: case report

P>AimTo present a 52-year-old male patient who complained of intense pain of short duration in the region of the left external ear and in the ipsilateral maxillary second molar that was relieved by blockade of the auriculotemporal nerve in the infratemporal fossa.SummaryExtra- and intraoral physical examination revealed a trigger point that reproduced the symptoms upon finger pressure in the ipsilateral auriculotemporal nerve and in the outer auricular pavilion. The patient's medical history was unremarkable. The maxillary left second molar tooth was not responsive to pulp sensitivity testing and there was no pain upon percussion or palpation of the buccal sulcus. Periapical radiographs revealed a satisfactory root filling in the maxillary left second molar. on the basis of the clinical signs and symptoms, the auriculotemporal was blocked with 0.5 mL 2% lidocaine and 0.5 mL of a suspension containing dexamethasone acetate (8 mg mL(-1)) and dexamethasone disodium sulfate (2 mg mL(-1)), with full remission of pain 6 months later. The diagnosis was auriculotemporal neuralgia.Key learning pointAuriculotemporal neuralgia should be considered as a possible cause of nonodontogenic toothache and thus included in the differential diagnoses.The blockade of the auriculotemporal nerve in the infratemporal fossa is diagnostic and therapeutic. It can be achieved with a solution of lidocaine and dexamethasone.

A interface entre distúrbio obsessivo-compulsivo e esquizofrenia: Desafios da prática clínica

The article discusses the relationship between obsessive-compulsive disorder (OCD) and schizophrenia, based on the report of eight clinical cases. It describes and discusses cases of OCD with poor insight, obsessions that seem paranoid delusions or auditive hallucinations, OCD with transient psychotic reactions, OCD with schizotypal personality disorder and schizophrenia with obsessive-compulsive symptoms.

Low-grade endometrial stromal sarcoma presenting as vaginal nodule

Endometrial stromal sarcoma is a rare neoplasm of the uterus. Extrauterine locations of this neoplasm, excluding metastases or local extension, are even more unusual and are usually associated with the presence of endometriosis. The authors report a case of endometrial stromal sarcoma presenting as a vaginal wall nodule, without any sign of primary uterine tumor after extensive evaluation or presence of endometriosis. The morphology, immunohistochemical profile, differential diagnoses, and pathogenesis are discussed, as well as a review of the literature on this issue. © 2004 Elsevier Inc. All rights reserved.

Feline cholangitis/ chonlangiohepatitis complex secondary to Platynosomum fastosum infection in a cat.

Platynosomiasis has been associated with cholangitis/cholangiohepatitis complex in domestic cats. Despite being typically asymptomatic, some individuals may develop severe disease resulting in hepatic cirrhosis. Definitive diagnosis by means of parasite eggs direct visualization is not always possible and complementary tests should be associated. This paper reports a case of a three-year-old female cat with anorexia and jaundice. Ultrasound and biochemistry laboratory findings as well as liver biopsy were not conclusive. Definitive diagnosis of intense Platynosomum fastosum infestation was only possible through direct examination of biliary fluid at necropsy, stressing the importance of including platynosomiasis, commonly an underdiagnosed disease, among differential diagnoses of feline liver diseases.

Olfactory reference syndrome: a still open nosological and treatment debate

Objective: The objective was to report a case of olfactory reference syndrome (ORS) with several co-occurring disorders and to discuss ORS differential diagnoses, diagnostic criteria and classification.Method: Case report.Results: A 37-year-old married woman presented overvalued ideas of having bad breath since adolescence. Shemet current diagnostic criteria for social anxiety disorder, specific phobia, obsessive-compulsive disorder, generalized anxiety disorder, body dysmorphic disorder and major depressive disorder. ORS similarities and differences with some related disorders are discussed.Conclusion: Further studies regarding symptoms, biomarkers and outcomes are needed to fully disentangle ORS from existing depressive, anxiety and obsessive-compulsive spectrum disorders.

Alterações hematológicas associadas ao hifema em cães

Hyphema is an intraocular hemorrhage that can result from many ocular and/or systemic disorders. It is an important clinical sign, since it may appear in the initial stages of some diseases or haematological disorders, acting as an initial marker for early diagnosis. The hematologic disturbances that predispose animals to present hyphema are: Thrombocytopenia, von Willebrand Disease, Scott Syndrome, Disseminated Intravascular Coagulation and Hyperviscosity Syndrome due to Multiple Myeloma. Each of the differential diagnoses due to hematological changes from the appearance of hyphema in dogs shows clinical relevance and particular ocular signs

Doença cerebelar em cães e gatos

Diseases of the cerebellar system are common in small animals, and result in a clinical syndrome characterized by hypermetria, base-wide stance and intentional tremors of the head and body. All movements of the limbs are spastic and awkward. The neurological examination assists in the localization of lesions restricted to the cerebellum or in the detection of disorders relating to other parts of the nervous system, which characterizes a multifocal disease process. Neurological disorders in dogs and cats may suggest a very extensive list of differential diagnoses, since they may be caused by infectious, degenerative and traumatic processes, among others. The possible etiologies for cerebellar syndrome include: aplasia and hypoplasia, abiotrophy, cancer, vascular stroke and inflammatory disorders. The aim of this paper is to review the clinical signs that aid in the location of the cerebellar lesion and discuss the possible causes of this syndrome in dogs and cats.

Hemocyte types and total and differential counts in unparasitized and parasitized Anastrepha obliqua (Diptera, Tephritidae) larvae

Os tipos de hemócitos e as contagens total e diferencial foram estudados em larvas parasitadas e não parasitadas de Anastrepha obliqua pertencentes ao início e ao final da terceira fase. em ambas as fases do desenvolvimento, tanto em larvas parasitadas quanto nas não parasitadas, foram observados pró-hemócitos, plasmatócitos, granulócitos, adipo-hemócitos, esferulócitos e oenocitóides. A presença de divisões mitóticas indica os pró-hemócitos como células-tronco. Pró-hemócitos, plasmatócitos e granulócitos são as células mais numerosas na hemolinfa de A. obliqua. Foi observada diferença no número total de hemócitos entre larvas parasitadas e não parasitadas apenas no final da terceira fase.

Optimum contribution selection using differential evolution

Um programa baseado na técnica de evolução diferencial foi desenvolvido para a definição da contribuição genética ótima na seleção de candidatos a reprodução. A função- objetivo a ser otimizada foi composta pelo mérito genético esperado da futura progênie e pela coascendência média dos animais em reprodução. Conjuntos de dados reais e simulados de populações com gerações sobrepostas foram usados para validar e testar o desempenho do programa desenvolvido. O programa se mostrou computacionalmente eficiente e viável para ser aplicado na prática e as consequências esperadas de sua aplicação, em comparação a procedimentos empíricos de controle da endogamia e/ou com a seleção baseada apenas no valor genético esperado, seriam a melhora da resposta genética futura e limitação mais efetiva da taxa de endogamia.
