Quizás el más notorio sea el del homosexualismo, que de ser tabú durante décadas se ha convertido en un motivo tratado con frecuencia por los escritores. A esto agrega que "la mayor parte de ellos ...realiza, más bien, una literatura posrevolucionaria, en el sentido de que la historia y el destino de la Revolución misma no parecen preocuparles" (25). Quienes busquen en estas narraciones los asuntos y personajes sobre los que ciertos autores promocionados por editoriales extranjeras insisten machaconamente (las penurias del llamado Período Especial, el deterioro físico y espiritual, el turismo sexual), comprobarán que los creadores jóvenes de la isla siguen unos derroteros estéticos y temáticos muy distintos.

Chronic venous insufficiency (CVI) comprises a complete spectrum of morphological and functional abnormalities of the venous system1 including any long-term functional and morphological alteration. ...CVI accounts for several abnormalities of the venous system. It is a highly prevalent disease that causes serious economic consequences, a decrease in the quality of life and can lead to serious complications. An exhaustive review was performed with the available literature, using the PubMed, ScienceDirect, Scopus and Cochrane databases from 2004 to 2021. The search criteria were formulated to identify reports related to chronic venous insufficiency. The pathophysiology of chronic venous insufficiency begins with chronic venous hypertension and the dilation of the vessel, this leads to a series of pathological changes in the venous wall and surrounding tissues, in advanced stages of CVI, skin lesions are associated with an increased proliferation of skin capillaries and microcirculatory abnormalities that may be the result of an altered level of factors responsible for the angiogenic response, such as vascular endothelial growth factor (VEGF), fibroblast growth factor 2 (FGF2) and angiostatin. In this review, updates on pathophysiology, clinic, diagnosis, classification and treatment of this disease are analyzed, with special emphasis on therapeutic options. Chronic venous insufficiency is a disease that affects the patient at several levels, mainly diminishing his/her quality of life. Currently there are various treatments ranging from habit modifications, pharmacological, to endovenous and surgical treatment.

Patients who undergo; anesthesia, neuraxial analgesia, or some type of neuraxial blockage are exposed to multiple complications. 33-year-old male patient, suffers a femur fracture with a long oblique ...trace causing pain and functional limitation for movements. Surgical resolution is determined using neuraxial block at L2-L3 level, and intravenous sedation. During his postoperative follow-up, a decrease in strength was confirmed in the lower limbs with 0/5 on the Daniels scale, 100% sensitivity without sphincter control, steroids were prescribed along with magnetic resonance imaging and a neurosurgical evaluation was requested. The MRI shows bulging of the fibrous annulus that obliterates the epidural fat and makes contact with the thecal sac in the L5-S1 intervertebral disc level. The neurosurgery service prescribes rehabilitation sessions at home, electrostimulation and neuropathic medications. Patient was discharged with rehabilitation sessions at home and medical treatment. In his last consultation, an evaluation from the psychiatry department was requested for ideas of disability, hopelessness, fantasies of death without a suicide plan related to limitations and loss of functionality. Patient does not return to external follow-up, cannot be located.

Background: They crayfish brain is segmented into two symmetrical hemiganglia. Normally both hemiganglia are in direct communication through a series of well-defined neural bridges that cross de ...midline to form reciprocal cross connections.Methods: An original study was carried out in the Department of Physiology of the Faculty of Medicine, UNAM during the period from August 2019 to August 2020. 13 Crayfish Procambarus clarkii weighing between 1g to 30g were used. Each eyestalk of the animals was tied to a displacement transducer coupled with a polygraph so that optomotor or electrical activity was bilaterally recorded. The separation of the right from the left hemiganglia from the cerebral or supraesophageal ganglion was performed with a sagittal section, splitbrain (SB).Results: The normal photo motor reflex in crayfish eye is measured as a gradual decrease in the ERG amplitude. During tactile stimulation, the visual activation of both eyestalks in normal crayfish leads to a highly regular bilateral activity. The regular activity can only be altered by disturbing the mechanoreceptors located in the shell surrounding the eyestalks.Conclusions: The procedure presented in this article provides unique characteristics for the study of the nervous system such as a detailed response of the bilateral optomotor reflex.
In spite of the fact that Machado de Assis is considered one of the great writers of the nineteenth century, outside Brasil his work does not have the diffusion or the recognition it deserves. This ...essay enumerates the history of the availlable translations of his novels and short stories in Spanish, analyzes the quality of some of those translations, and reflects, on the causes of the limited reception hi literary works have in Latin America.
A pesar de que unánimemente se le considera uno de los grandes escritores del siglo xix, fuera del Brasil la obra de Machado de Assis no tiene la difusión y el reconocimiento que merece. En este trabajo se hace un recuento histórico de las traducciones al español de sus novelas y cuentos, se analiza la calidad de algunas de esas versiones y se reflexiona sobre las causas de la escasa presencia que su obra literaria tiene en los países de Hispanoamérica.
The reconstruction of the injured tissue around the knee is a complex procedure for the plastic and orthopaedic surgeon. The objective is to provide an acceptable function and aesthetic result. ...Successful wound management includes meticulous debridement, planning and proper execution of the surgical procedure. An 11-year-old male patient with a right patellar fracture using an anterolateral thigh flap with reverse flow to cover the skin defect. For such purposes, the reverse flow anterolateral flap is an effective, trustworthy and well-documented option. The correct obtaining and implantation of the flap reduces the morbidity of the donor site, offers options in size and design, an adequate length of the pedicle and the possible combination with the fascia lata in case it is required. The versatility of the reverse flow anterolateral flap makes it a possible therapeutic alternative in reconstructive surgery since it is aesthetic and functional for the reconstruction of tissue near the knee joint.
