The Hermanos Ameijeiras Hospital, officially the Hospital Clínico Quirúrgico "Hermanos Ameijeiras", is located in Barrio San Lazaro and is the premier hospital in Cuba, its tower prominently visible from the Malecón between the historic center and the uptown Vedado neighborhood. It was opened in 1982. According to EcuRed, the Cuban state wiki, it was "created by the Revolution to offer the people service in a best-in-class, world-class environment" ("creada por la revolución para brindar al pueblo una atención en el ámbito de los mejores centros de su clase en el mundo")The hospital is located at San Lázaro and Belascoaín streets in Centro Habana. It has a footprint of 35,500 square metres (8.8 acres), and 79,500 square metres (856,000 sq ft) of floor space. The monumental lobby measures 75 metres (246 ft) by 45 metres (148 ft) with a 15-metre-high (49 ft) ceiling and murals by Romanian-Cuban artist Sandú Darié.
Introducción: Los meningiomas quísticos son tumores infrecuentes. El diagnóstico preoperatorio es complejo debido a su confusión con otros tumores intracraneales de origen glial con componentes quísticos o con metástasis. Objetivo: Presentar un caso de meningioma quístico, de aparición infrecuente en la práctica neuroquirúrgica. Caso clínico: Paciente femenina, de 54 años de edad, con cuadro clínico de trastornos conductuales y cefalea holocraneal de gran intensidad, de alrededor de un mes de evolución y difícil control con analgésicos. Los estudios de neuroimagen mostraron una lesión ocupativa de espacio en la región frontal izquierda, con nódulo tumoral y quiste asociados. Los estudios de extensión de metástasis fueron negativos. Se realizó una craneotomía frontal y una exéresis tumoral total guiada por endoscopia. El examen histopatológico evidenció meningioma meningotelial de grado 1. La evolución de la paciente fue satisfactoria. Conclusiones: El diagnóstico erróneo de los meningiomas quísticos puede ocasionar tratamientos inadecuados.
The principal objective of this investigation is to implement a portable and low-cost system for the real-time analysis of blood flow using mobile technology. The methodology employs a specialized application developed in Kotlin for the Android platform. This software captures audio signals from a continuous-wave Doppler ultrasound device and applies digital signal processing techniques, including high-pass filtering and the Fast Fourier Transform (FFT), to generate high-resolution spectrograms. The results demonstrate that the application accurately calculates essential hemodynamic parameters, such as mean blood velocity, pulsatility index, and resistive index, directly on the mobile device. The principal conclusion is that this tool significantly advances the Point-of-Care Ultrasound (POCUS) model by providing a reliable and accessible solution for the early detection of subclinical atherosclerosis, particularly in environments with limited clinical resources.
This manuscript describes the characteristics of a dataset with EEG recordings of 173 participants: 87 confirmed COVID-19 cases (positive Reverse Transcription Polymerase Chain Reaction RT-PCR) and 86 healthy close contacts (negative PCR). EEG was acquired using a 10–20 standard montage. Resting EEG was recorded for 8 minutes in all participants with eyes closed. Afterwards, it was also recorded 2 minutes of alternating closed and open eyes, followed by 2 minutes of recovery. All participants underwent physical, neurological, and clinical evaluations, including a retrospective neurological survey and the Schedules for Clinical Assessment in Neuropsychiatry (SCAN) version 2.1.
Background Left atrial appendage aneurysm (LAAA) is an exceptionally rare cardiac abnormality that may be congenital or acquired. Although many patients remain asymptomatic for years, common presentations include palpitations, dyspnoea, and thromboembolic events.Case summary A 30-year-old woman with no medical history presented with 2 weeks of palpitations and exertional dyspnoea. Examination revealed mild congestion and an irregular rhythm. Electrocardiography showed atrial fibrillation with a slightly rapid ventricular response. Chest radiography demonstrated a prominent left mediastinal border. Transthoracic echocardiography identified a large congenital LAAA adjacent to a normal-sized left ventricle with moderately reduced ejection fraction. She improved with intravenous diuretics, anticoagulation, and guideline-directed medical therapy. Given her preference for conservative therapy, she was discharged on rivaroxaban. She remained asymptomatic during follow-up.Discussion LAAA should be suspected in patients with unexplained left-sided mediastinal enlargement and atypical echocardiographic findings. Imaging is essential for diagnosis, and surgical aneurysmectomy is considered curative, although evidence guiding management in asymptomatic individuals is limited. Selected patients may be managed conservatively with close follow-up.
