“…Pulmonary ventilation increases significantly during the luteal phase whereas cardiorespiratory fitness and peak heart rate were highest in the post-menstrual phase and lowest during the flow phase. 13,14 However, contradictory findings indicated that cardiorespiratory fitness did not alter in different phases of menstrual cycle. 15,16 Many studies suggested that different phases of menstrual cycle do not affect the physical performance.…”

BackgroundAlteration in physical work capacity of females during different phases of menstrual cycle has been reported in different populations. Pertinent data is unavailable in Eastern Indian population. ObjectivesThe present study was aimed to determine the endurance capacity and cardiorespiratory responses during different phases of menstrual cycle in young sedentary females of Eastern region of India. MethodsForty five unmarried young healthy sedentary females (21-25 years) were recruited in the present investigation. Duration of their menstrual cycle was 28-30 days. Cardiorespiratory parameters including the endurance capacity was determined by treadmill running with constant monitoring of heart rate by Polar heart rate monitor. ResultsThe pre-exercise heart rate was significantly higher (P<0.02) in the luteal phase. The peak heart rate was significantly lower (P<0.02) in the flow phase than the follicular and luteal phases. VO 2max , O 2 pulse, maximum pulmonary ventilation and endurance capacity were significantly lower in the follicular phase. However, the endurance capacity was significantly lower in the flow phase. Pre-exercise systolic and diastolic blood pressure did not exhibit any significant variation in different phases of menstrual cycle. ConclusionTherefore, from the present observations it may be concluded that pre-exercise heart rate and respiratory rate are significantly higher in the luteal phase whereas VO 2max , O 2 pulse, maximum pulmonary ventilation, endurance capacity and peak heart rate were significantly lower in the follicular phase.

“…La función pulmonar sigue siendo la misma durante el embarazo 43 . El volumen espiratorio forzado en el primer segundo (VEF1) y la proporción VEF1/capacidad vital forzada (CVF) se mantiene sin cambios en el embarazo, así como las tasas de flujo espiratorio máximo 44,45 . Por lo tanto, es razonable utilizar los valores de referencia en no embarazadas para evaluar la función pulmonar en mujeres grávidas.…”

Este libro constituye la recopilación de diferentes capítulos que integran conocimientos de las ciencias básicas medicas y la semiológica, cuya aplicación es necesaria al enfrentarse a una paciente con una dolencia ginecológica u obstétrica. El objetivo es que la suma de estos conocimientos a ciertas habilidades en la relación medico-paciente, dé como resultado una anamnesis y un examen físico exhaustivo y pertinente. Lo anterior dentro del marco del respeto por el pudor de una paciente que responderá preguntas intimas y dejara examinar sus genitales. El estudiante, a lo largo del texto, recibirá elementos que el permitirán generar una historia clínica completa y ordenada, y que aporte los argumentos para un adecuado aná-lisis, un diagnostico acertado y una plan racional de ayudas diagnosticas y tratamiento medico o quirúrgicos. Los estudiantes de pregrado en el rea de la salud que inicia su ciclo en ginecología y obstetricia requieren un texto que les refuerce la fundamentación anatómica y fisiológica, y que al mismo tiempo correlacionen dicha fundamentación anatómica y fisiológica, y que al mismo tiempo correlaciones dicha fundamentación con la semiología y el proceso diagnostico. Los textos disponibles, la mayoría de muy buena calidad académica, suelen ser muy extensivos, excesivamente detallados y mas enfocados al abordaje terapéutico. Ademas su costo generalmente es elevado. Por otro lado los textos de Semiología no profundizan lo suficiente en la semiología de ginecológica y obstétrica. El análisis anterior puso de manifiesto la necesidad de construir el compendio Fundamento de Ginecología y Obstetricia, que permita al estudiante integrar sus conocimientos en embriología, anatomía, histología y farmacología a la semiología, en la entrevista medica y en el examen fisco; facilitando el objetivo final de elaborar una historia clínica analítica, bien fundamentada y que cumpla con los requerimientos académicos y legales actuales. No obstante, para alcanzar este objetivo el estudiante deberá estudiar el texto con profundidad y ante todo, aplicar estos conocimientos en la practica de sus rotaciones clínicas dentro las cuales tendrá contacto con pacientes. Esperamos entonces que este compendio sea un aporte al aprendizaje de un adecuado proceso diagnostico y por consiguiente terapéutico, de las patologías en Ginecología y Obstetricia.

“…It is important for clinicians who care for pregnant women with sarcoidosis to be aware of the changes in physiology and pulmonary function and that occur in these conditions [39][40][41][42][43]. There is an increase in resting minute ventilation during pregnancy which leads to increased alveolar ventilation.…”

Sarcoidosis is a multisystemic disease of unknown etiology, characterized by granulomatous inflammation. It typically presents between the ages of 20 to 40 years old. An estimated 0.02% to 0.05% of pregnancies occur in patients with sarcoidosis. Although fetal loss has been reported in mothers with sarcoidosis, limited studies do not suggest an increase risk of fetal or neonatal complications. Several reports suggest an improvement of sarcoidosis during pregnancy. Sarcoidosis, a Th1-mediated disease, seems to follow the same course as rheumatoid arthritis during pregnancy and postpartum. Estrogen levels increase during pregnancy, resulting in a decreased Th1-mediated immune response, which can improve active sarcoidosis. Free plasma cortisol concentrations increase in pregnancy, with plasma levels 2-to 3-fold higher than those of non-pregnant controls, suggesting greater tissue exposure to glucocorticoids during pregnancy. This may result in decreased granulomatous inflammation with improvement in symptoms and clinical findings. During the postpartum period, when free cortisol levels return to the prior non-pregnant levels, reactivation of sarcoidosis can occur. The majority of patients with sarcoidosis will either have a stable disease or will experience improvement in their symptoms. A small group of pregnant mother with active sarcoidosis, however, may develop more progressive disease during pregnancy. The manifestations, course of disease, and treatment options during pregnancy and postpartum period are discussed.
