Congenital middle ear malformations are rare. Most part of them are usually associated with other malformations, such as aural atresia, microtia, and dysmorphic craniofacial features. A clinical case of a 24-year-old male with a right-sided conductive hearing loss since his childhood, without craniofacial malformation, is presented. He was proposed for exploratory tympanotomy under the suspicious diagnosis of otosclerosis. The surgery revealed an abnormal location of stapes' superstructure, which was attached to the promontory and had an isolated and mobile osseous footplate in the oval window. A stapes prosthesis was inserted and resulted in closure of the air-bone gap by 25 dB. A review of the literature was also performed using MEDLINE. Two theories diverge on the embryologic origin of the stapes. Our findings seem to be in favour of the theory that defines two different embryologic origins to the stapes.
IntroductionThe diagnosis of the main psychiatric syndromes is still almost exclusively phenotypic and depends essentially of the recognition of characteristic signs and symptoms. The clinical evalution allows the formulation of a set of differential diagnoses, according to the pathological meaning of certain symptomatic patterns and combinations. Aside from the entire dependence on the clinical interview, there are still no complementary psychiatric diagnostic exams and it is also worth noting the absence of pathognomonic symptoms.ObjectivesThrough the presentation of the case of a patient with Bipolar Affective Disorder who manifests, during a manic episode, a Capgras delusion, we intend to approach the heterogeneity of the manifestation of some symptoms that tend to be specific of concrete psychiatric syndromes.MethodsClinical case presentation and non-systematic literature review using Pubmed plataform.ResultsAB, female, 49 years old, diagnosed with Bipolar Affective Disorder. Hospitalized for a manic episode with dysphoric mood, increased energy levels and delusional activity of grandiose and persecutory content. During hospitalization, a Capgras delusion centered on the husband emerged: he was replaced by a stranger, I was able to detect him by smell.Capgras delusion is a delusional misidentification syndrome characterized by the belief that someone close has been replaced by an imposter. Despite being a rare syndrome, vastly more common in schizophrenia, affecting about 73% of cases, it can also occur in other psychiatric conditions such as dementia syndromes and, less often, mood disorders (16.7%).Additionally, there are several examples that demonstrate the versatility of psychiatric symptom occurrence in different diagnoses, with first-rank symptoms serving as an example. Described in 1959 by Kurt Schneider, they were considered specific symptoms of schizophrenia, assuming this diagnosis based on the recognition of only one symptom. Over time, its pathognomonic character has become extinct, and its detection in mood disorders and acute psychotic disorder is relatively common.Another example is the overlap between depressive and anxious symptoms. In fact, anxiety symptoms occur in about 85% of patients diagnosed with depressive disorder and, in turn, the presence of depressive symptoms in about 90% of patients diagnosed with anxiety disorder. This evidence has allowed, over time, a review of the diagnostic criteria for these disorders, leading to a progressive blurring of the threshold between them.ConclusionsPsychiatric diagnosis is still a delicate task, totally dependent on the clinical interview. The lack of analytical and imaging tests, as well as the absence of pathognomonic symptoms, constitute a particular challenge in diagnosis. For this reason, we highlight the importance of recognizing combinations and patterns of symptoms rather than the specificity of just one symptom.Disclosure of InterestNone Declared
IntroductionAlthough evidence of cannibalism in humans dates back millennia, for most civilized societies, it is an unthinkable act of violence and strictly taboo. It is commonly relegated to the domain of horror films and literature, often associated with the likes of Jeffrey Dahmer or Hannibal Lecter. However, for some, this theme encompasses a pathological or sexual realm. Vorarephilia or sexual cannibalism is, at its simplest level, a psychosexual disorder characterized by the erotic desire to be consumed by, or to personally consume, another human being´s flesh.ObjectivesThe authors aim to review human sexual cannibalism as a concept and its eventual relationship to mental illness with recourse to the description of cases of human cannibalism documented in the literature.MethodsA brief non-systematized literature review utilizing various databases including Pubmed and Google Scholar, as well as complimentary literature and case reports when pertinent to the theme was performed.ResultsAlthough cannibalism is a common phenomenon in the animal kingdom, its expression in humans is assumed to be a minority occurrence and relegated to stories of a more primal past. Pathological cannibalism is an extremely rare occurrence and has been described in association with severe psychotic mental illness and extreme forms of significant paraphilia. Sexual cannibalism appears as a rarity in humans and although the majority with this paraphilia do not partake in actual human consumption, remaining a fantasy-based desire, cases of cannibalism have been reported and tried.ConclusionsEating the flesh of one’s own species is probably one of the few remaining taboos in modern human societies. In humans, cannibalism is a rare occurrence and has been associated with mental illness. Due to the rarity of this phenomenon, with few cases documented in the literature, the underlying etiology, as well as potential environmental and individual risk factors are still to be defined, indicating a potential for further study.Disclosure of InterestNone Declared
