| Popis: | Anhidrotic ectodermal dysplasia is a congenital syndrome characterized by the absence of sweat glands. A sweating test was performed on such a patient and proved his inability to sweat. Thermal exchanges during night sleep were then measured in this patient and compared with data obtained from a healthy control subject. Ambient conditions were as follows: dry bulb temperature 32.2°C, relative humidity 30%–40%, wind speed 0.7 m·s−1. Polysomnographic recordings showed normal sleep patterns in both subjects, but a “first night effect” in the patient.

Loss of mass averaged 34.1 g·h−1 in the patient vs 78.1 g·h−1 in the control subject. No relationship with sleep stages was observed in the patient, in contrast to the control subject who experienced a decrease in evaporation during rapid eye movement sleep. Body temperatures varied little in the patient, but decreased until the 6th h of sleep in the control subject. On two occasions there was a 0.3°C fall in theT re of the patient during two slow wave sleep (SWS) phases, while % MathType!MTEF!2!1!+-% feaafiart1ev1aaatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbuLwBLn% hiov2DGi1BTfMBaeXatLxBI9gBaerbd9wDYLwzYbItLDharqqtubsr% 4rNCHbGeaGqiVu0Jf9qqqrpepC0xf9qiW7rqqrFfpeea0xe9LqFf0x% c9q8qqaqFn0dXdir-xcvk9pIe9q8qqaq-xir-f0-yqaqVeLsFr0-vr% 0-vr0xc8meaabaqaciGacaGaaeqabaWaaeaaeaaakeaaceWGubGbae% badaWgaaWcbaacbaGaa83Caiaa-Tgaaeqaaaaa!3CE7! $$\bar T_{sk} $$ and loss of mass did not change. As thermolytic processes had not varied on these two occasions, it was concluded that the fall inT re indicated a concomitant decrease in metabolic heat production, in agreement with the assumption that SWS represented a state of energy conservation. |
