Correlación Entre Calidad de Sueño y Calidad de Vida en Estudiantes de Medicina. Correlation Between Quality Of Sleep And Quality Of Life In Medical Students.

Introduction: Sleep is important for the proper performance of the individual since it participates in many biological processes. Medical students often do not get the recommended amount of sleep per day, this affects their quality of sleep, with repercussions on their quality of life.

Objective: To identify the association between sleep quality according to the Pittsburgh Sleep Quality Index (PSQI) questionnaire and quality of life according to the World Health Organization Quality of Life (WHOQOL–BREF) questionnaire of the World Health Organization (WHO) and describe the most prevalent risk factors for sleep disorders in medical students from the Catholic University Santiago de Guayaquil (UCSG).

Methods: Cross-sectional observational study in UCSG medical students.

Results: The questionnaires were completed by 211 students; the mean age was 20,8 ± 2,6 years; 62,1% were women. The mean BMI was 23,1 ± 3,8, 20,4% of the students were overweight and 4,3% were obese. The mean score in the PSQI obtained in the study population was 7,2 ± 3,1 and in the WHOQOL – BREF was 60,9%. Pearson’s correlation coefficient, r2, between both variables was -0.33 (p: <0.01).

Conclusion: Poor quality of sleep is inversely correlated with quality of life. The quality-of-life domain most associated with poor sleep quality was the physical domain. The most frequent risk factor for poor quality sleep was snoring.

Fundamentos Neurobiológicos del Sueño. Neurobiological Basis Of Sleep

Sleep is one of the most important behaviors for the cognition of the human being. It has between 4 to 6 cycles that are characterized by presenting different electromagnetic activity that causes a certain brain activity to occur in each of them. When the sleep pattern is affected, there are alterations in the daily life of the subject who suffers it, generating a negative impact on the activities carried out in the personal, family and social environment. In this article we report a theoretical review of the dream, its electrical activity during each of its phases, sleep disorders and the impact of sleep disorders on the individual’s life. It is concluded by emphasizing the role of maintaining a balance in the sleep pattern as a benefit for the daily life of the subject.

Bases anatómicas y fisiológicas del sueño.

Sleep study has rarely been important until the past few years, although its pathology deserves special attention from the medical point of view. The present work intends, with update knowledge, to review in a summarized and practical way, the anatomical basis and mechanisms involved in sleep, its types, and the regulation sleep-wakefulness cycle. This will be helpful for a better understanding of its function and will permit an adequate management of its pathology.

Epilepsia Parcial Benigna Atípica de la Infancia: Presentación de un Caso Peculiar y Revisión de la Bibliografía.

Introduction: Atypical benign partial epilepsy of childhood is a rare form of epilepsy characterized by a combination of partial seizures, as observed in Partial Benign Epilepsy of Childhood, as well as with centre-temporal paroxysms and generalized seizures; showing furthermore, a continuos peak wake electroencephalographic pattern characteristic of NREM sleep.

Clinical Case: Patient presenting with partial seizures is admitted to the hospital with EEG findings compatible with continuos peak wave electric status of NREM sleep.
