Angioma esplénico de células litorales

A 62-year-old man with a medical history of a painful abdominal mass in left upper quadrant and general symptoms, who was classified initially as an unresectable sarcoma. He received chemotherapy and radiotherapy with no response, so he underwent a new surgery, finding a heterogeneous tumor with immunohistochemical consistent with littoral cell angioma. Littoral cell angioma (LCA) is a rare splenic lesion that presents general symptoms, so there are not many reports, which requires surgical management. Is usually an asymptomatic neoplasm of incidental finding, affecting both sexes equally, whose diagnosis is histological and immunohistochemical with a good prognosis always after a surgical approach.Presentamos el caso de un paciente varón de 62 años con masa dolorosa en hipocondrio izquierdo catalogado inicialmente como sarcoma irresecable, recibió quimioterapia y radioterapia sin respuesta, motivo por el cual se reintervino quirúrgicamente hallándose un tumor dependiente de bazo heterogéneo con perfil inmunohistoquímico de angioma de células litorales. El angioma de células litorales (ACL) es una lesión esplénica poco frecuente que se presenta asociado a síntomas genéricos como astenia, dolor regional y baja de peso, que requiere como manejo principal un abordaje quirúrgico. Suele ser una neoplasia asintomática de hallazgo incidental, afecta a ambos sexos por igual, cuyo diagnóstico es básicamente histológico e inmunohistoquímico con buen pronóstico luego de un abordaje quirúrgico inicial

Grambank reveals the importance of genealogical constraints on linguistic diversity and highlights the impact of language loss

While global patterns of human genetic diversity are increasingly well characterized, the diversity of human languages remains less systematically described. Here we outline the Grambank database. With over 400,000 data points and 2,400 languages, Grambank is the largest comparative grammatical database available. The comprehensiveness of Grambank allows us to quantify the relative effects of genealogical inheritance and geographic proximity on the structural diversity of the world's languages, evaluate constraints on linguistic diversity, and identify the world's most unusual languages. An analysis of the consequences of language loss reveals that the reduction in diversity will be strikingly uneven across the major linguistic regions of the world. Without sustained efforts to document and revitalize endangered languages, our linguistic window into human history, cognition and culture will be seriously fragmented.Genealogy versus geography Constraints on grammar Unusual languages Language loss Conclusio

An updated review on the neuropsychological profile of subjects with bipolar disorder

Abstract Background In recent years, growing interest in the neuropsychology of bipolar disorder has emerged, giving rise to the accumulation of a robust body of evidence on this topic and to several related questions. Objective To provide a state-of-the-art overview of the neuropsychological profile of bipolar disorder. Method A thorough literature search was performed. Published research evidence was summarized and organized along three key pathways: findings from cross-sectional studies of cognition in bipolar patients, cognitive heterogeneity among affected subjects, and trajectory of neuropsychological deficits. Results At least two thirds of bipolar patients display neuropsychological deficits, even in euthymia. Although bipolar disorder was found to be associated with an increased risk of dementia, data from elderly subjects and longitudinal research do not support a worsening of cognitive performance over time. Discussion Cognitive dysfunctions are part of the clinical conceptualization of bipolar illness. However, they may not be present in all affected subjects and their course appears to be stable in most cases. Available evidence may be highlighting the fact that bipolar disorder is characterized by remarkable heterogeneity regarding cognitive outcomes. Different variables may be related to such heterogeneity and should be the focus of therapeutic approaches and further research

Intrapancreatic common hepatic artery arising from the superior mesenteric artery, a challenging anatomic variation in a multiorgan harvesting

Introduction: Understanding abdominal vascular anatomy is crucial for multiorgan recovery. In this case report, we have described a common hepatic artery that arises from the superior mesenteric artery but follows an intrapancreatic course. Methods: The donor was ideal for multiorgan recovery and the recipient was a 29-year-old woman awaiting a second transplant owing to primary nonfunction of her first engrafted organ. The indication for transplantation was secondary biliary cirrhosis. A type I diabetic recipient on dialysis therapy was awaiting the kidney and pancreas. Results: The urgent condition of our liver recipient combined with the anatomical finding prioritized liver procurement, therefore the pancreas was discarded. Conclusions: The recognition of all anatomic variations will allow us to improve the use of the scarce resource of deceased donor organs. © 2013 Elsevier Inc.Fil: Padín, J. M..

Behavioral and emotional adverse events of drugs frequently used in the treatment of bipolar disorders:clinical and theoretical implications

BACKGROUND: Behavioral and emotional adverse events induced by drugs commonly prescribed to patients with bipolar disorders are of paramount importance to clinical practice and research. However, no reviews on the topic have been published so far. METHODS: An extensive search was performed. Reports were reviewed if they described behavioral side effects related to pharmacological treatments for bipolar disorders in healthy subjects or patients with different neuropsychiatric disorders. For this review, lithium, antipsychotics, anticonvulsants and selective serotonin reuptake inhibitors were included. RESULTS: Apathy or emotional blunting, diminished sexual desire, and inability to cry were reported to be associated with exposure to selective serotonin reuptake inhibitors. Neuroleptic-induced deficit syndrome/emotional detachment and obsessive–compulsive symptomatology and decision-making modifications. A lithium-related amotivational syndrome was also reported in the literature. Furthermore, hypersexuality and obsessive–compulsive symptoms have been noted in subjects treated with lamotrigine. LIMITATIONS: Primary studies on drug-related adverse events are scant so far and most of the data currently available derive from case reports. Moreover, most of the evidence reviewed is based on studies performed on healthy subjects and patients with neuropsychiatric conditions other than bipolar disorders. DISCUSSION: There is a remarkable dearth of data on behavioral adverse events of pharmacological treatment for bipolar disorders. However, the pieces of evidence available at present, though scant and scattered, suggest that different behavioral adverse events may be related to pharmacological treatment for these disorders. The implications of these findings for research and management of patients with mood disorders are discussed
