The National Institute of Neurology and Neurosurgery is one of the great Institutions of the health sector, which has been and is a source of pride for the country and I want to emphasize that the creation of this Institute was due to a great character in world Neurosurgery, the teacher Don Manuel Velasco Suárez; It is very important to know that this institution was conceived and created last century and inaugurated in 1964 to be a unique work in the world, since with the great visionary mind of Don Manuel, I place in the same physical space the three great branches of Neurosciences: Neurosurgery, Neurology and Psychiatry, which did not exist.

Background: Alveolar soft part sarcoma (ASPS) is a rare, slow-growing soft tissue tumor with uncertain etiology; it is considered among the least common sarcomas, representing 0.2-1% of these cases in large studies. These tumors usually appear during childhood or young patients, with predominance in females. Case description: We introduce the case of ASPS in a 62-year-old man, who presented with 7 months of progressive headache and diplopia. The brain MRI showed an infiltrative lesion in the anterior fossa that extended to the right orbital roof. The possibility of metastasis was ruled out. The patient underwent resection of the tumor with posteriorly good visual and neurologic recovery. Histologic characterization demonstrated homogeneous eosinophilic cells with a solid, vascularized pattern, cells with large and binucleated nucleoli, and vessels with endothelial and myoepithelial hyperplasia; numerous apoptotic bodies and mitosis figures were also present, but no necrosis. On immunohistochemistry, cells exhibited positive CD56, NSE in membrane form, and slight myogenin; vessels were strongly positive for myogenin, myoglobin, CD34, CD31, factor VIII, vimentin, and nestin as well as for HBM45, CD20, GFAP, and S-100; cytokeratin showed fine extracellular and intracellular filaments; GATA and TTF1 were negative. Some clear cells were observed to be positive for CD68. The piece was diagnosed as a non-meningeal alveolar sarcoma of the soft tissue with solid pattern. Discussion and Conclusion: This case corresponds to the second tumor of this kind presented at our institution, the first one reported, and perhaps, one of the oldest patients to develop it worldwide.
背景:肺泡软组织肉瘤(Alveolar soft part sarcoma, ASPS)是一种罕见的、生长缓慢的软组织肿瘤，病因不明;它被认为是最不常见的肉瘤之一，在大型研究中占这些病例的0.2% -1%。这些肿瘤通常出现在儿童或年轻患者，以女性为主。病例描述:我们介绍一名62岁男性的ASPS病例，他表现为7个月的进行性头痛和复视。脑部MRI显示前窝浸润性病变延伸至右眶顶。转移的可能性已被排除。患者术后视力及神经功能恢复良好，行肿瘤切除术。组织学特征显示均质嗜酸性细胞呈实心血管化模式，核仁大且双核，血管内皮和肌上皮增生;可见大量凋亡小体和有丝分裂图，但未见坏死。免疫组化显示细胞CD56阳性，膜状NSE阳性，肌原素轻微;血管中肌原蛋白、肌红蛋白、CD34、CD31、因子VIII、vimentin和巢蛋白以及HBM45、CD20、GFAP和S-100呈强阳性;细胞角蛋白呈胞外和胞内细丝;GATA、TTF1均为阴性。部分透明细胞CD68阳性。片被诊断为非脑膜肺泡肉瘤的软组织实型。讨论与结论:该病例是我们医院报告的第二例此类肿瘤，也是第一例报道的肿瘤，可能是世界上最古老的肿瘤患者之一。

La depresión, la ansiedad y la epilepsia son afecciones del Sistema Nervioso Central (SNC) que causan sufrimiento y morbilidad entre la población mexicana. Si bien existen fármacos para su terapéutica, en ocasiones éstos resultan ineficaces y promueven efectos adversos que conllevan a la falta de apego por parte del paciente. Especies del género Annona son utilizadas en la medicina tradicional Mexicana por sus propiedades inhibitorias del SNC, de los cuales ya se han reportado sus propiedades como ansiolítico-sedantes y anticonvulsivos, además de sus propiedades como anticancerígenos, antioxidantes y anti-inflamatorios. El objetivo de este estudio consistió en realizar un cernimiento de los posibles efectos inhibidores en el SNC de la especie Annona reticulata (A. reticulata) sobre modelos experimentales en roedores. Método: A. reticulata se utilizó preparada como un extracto etanólico, para evaluar sus efectos como ansiolitico y antidepresivo en la prueba de nado forzado y como anticonvulsivo en la prueba de crisis convulsivas inducidas con pentilentetrazol en ratas, también se probó su efecto como ansiolítico en la prueba de enterramiento de canicas. Imipramina, valproato de sodio y diazepam se utilizaron como fármacos de referencia, respectivamente. Resultados: A. reticulata redujo la conducta depresiva, además aumentó la latencia y disminuyó la severidad de las crisis convulsivas, y disminuyó la respuesta tipo ansiedad de los ratones. Conclusión: este estudio da evidencia preclínica de las propiedades como antidepresivo, ansiolítico y anticonvulsivo de las hojas de A. reticulata, reforzando su potencial en la búsqueda de alternativas para afecciones del SNC.

Introducción: El Síndrome de Acento Extranjero (SAE) una entidad rara, los pacientes desarrollan cambios en el ritmo y tono del habla (prosodia), percibidos como un acento diferente al de su lengua natal. Existen tres tipos de SAE: neurogénico, psicogénico y mixto. El SAE es infrecuente en EM, y aún más como síntoma debut. Objetivo. Revisión del SAE, tipos, fisiopatología y presentación en EM y evolución. Desarrollo. El SAE Las lesiones corticales en EM se correlacionan con deterioro cognitivo, discapacidad motora, síntomas psiquiátricos, alteraciones del lenguaje, síntomas conversivos y crisis epilépticas. La mayoría de los casos publicados de SAE han sufrido lesión en el hemisferio dominante, en corteza prerrolándica y áreas adyacentes, áreas motoras frontales de asociación, en putamen, ganglios basales, fosa posterior (protuberancia, cerebelo), por diferentes etiologías siendo la más frecuente la vascular. Compartimos un caso clínico: mujer, 44 años debuta con SAE interpretado inicialmente como infarto cerebral en quien finalmente se concluyó el diagnóstico de esclerosis múltiple. Ha tenido mejoría parcial de los síntomas posterior a rehabilitación fonoaudiológica. Conclusiones. SAE es una presentación infrecuente de debut de EM. Debe considerarse la etiología desmielinizante en pacientes jóvenes, con escasos o sin factores de riesgo vascular y apoyarse en estudios complementarios de neuroimágenes.

Resumen El trastorno psicótico compartido o folie à deux es un síndrome psiquiátrico de presentación más frecuente de lo que tradicionalmente se creía o consignaba la literatura especializada hasta hace algunos pocos años. Dos factores han contribuido de manera determinante para que empiece a ser considerado como una entidad clínicamente significativa: a) una mejor evaluación familiar y del entorno social de los enfermos diagnosticados como psicóticos y, b) la identificación precisa de los casos, muchos de los cuales son rescatados de la literatura y la historia, a veces con más carácter anecdótico que científico. Es importante señalar que entre más se hurga en el pasado, se ha encontrado que es tan antiguo como lo puede ser la humanidad misma. En el presente trabajo de investigación se describe un caso que presenció unos de los héroes más significativos del continente americano y el mundo occidental. La importancia radica no sólo en la trascendencia del personaje involucrado, sino que además se trata de una variante clínica raramente descrita denominada psicosis alucinatoria inducida.

A 56 year-old woman presented with new onset focal seizure with a history of bronchiectasis. Brain abscess was diagnosed by magnetic resonance. She was confirmed to be immunocompetent and had histoplasmosis, tuberculosis, and infective endocarditis ruled out. Nocardia sp. was isolated from the brain abscess and identified as Nocardia abscessus complex by 16S rRNA sequencing. She was discharged on trimethoprim/sulfamethoxazole. Nocardia sp. is a cause of brain abscesses in patients with underlying pulmonary structural disease like bronchiectasis. Nocardia identification is of paramount importance as it is not treated with empiric antimicrobial therapy.

Introduction: Attention-Deficit/Hyperactivity Disorder (ADHD) in adulthood causes relevant deterioration in daily functioning. Specifically, in educational scenarios, complications including an elevated rate of failed courses and desertion have been found. The reported prevalence of ADHD in adults varies widely, therefore studying specific populations becomes important. Objective: to determine the prevalence of ADHD in students at a public university using screening tools to determine the presence of current and retrospective symptomatology during childhood and to describe their sociodemographic characteristics. Method: the study was conducted with a probabilistic sample of undergraduate students (N = 1837), to whom the Adult Self Report Scale for ADHD (ASRS-6) and the Wender Utha Rating Scale (WURS) were administered to determine current and childhood ADHD symptoms. Results: the prevalence of ADHD in the studied population was 16.2%, with a significantly higher frequency in males (22.14%) than in females (13%). ADHD was most prevalent in Biology students (23.7%) and least in Nursery students (9.9%). Discussion and conclusion: results indicate a higher frequency of ADHD in Mexican undergraduate students than that reported in adult populations of other countries, but consistent with previous reports of Mexican undergraduate students and children. The association of ADHD and difficulties in academic, work, and social achievement in the studied population should be further investigated.
