US Guided Si.La.D. A new technique for minimally invasive pilonidal disease treatment, using ultrasound guided laser ablation.

: The destruction of the pilonidal sinus with a radial laser probe has been suggested as a safe procedure with good results and low morbidity. Nevertheless, the drawbacks of this technique are: a blind technique, if the sinus has some ramifications or a non-linear development, we cannot be sure for their destruction. patients (12 men, 5 women) were operated with US guided laser destruction - US guided Si.

Anthropometric, hemodynamic, metabolic, and renal responses during 5 days of food and water deprivation.

Background: Although there is considerable research in the field of fasting and fluid restriction, little is known about the impact of food and water deprivation (FWD) on body circumferences and vital parameters.

Methods: During 5 days of FWD in 10 healthy adults, hemodynamic, metabolic, and renal parameters, such as weight, 5 circumferences at neck, waist, hip, chest at axilla, chest at nipples, and 1 new oblique hip circumference were measured daily. For each circumference, new quotients of daily circumference-to-weight decrease were calculated.
