Aarskog's syndrome. Description of a case and endocrinological study
No full textA 7-year-old male with the Aarskog Syndrome is described. This observation is the seventh of the italian literature. The child had the typical findings of the syndrome: short stature, abnormal facies, short fingers with interdigital webbing, unusual scrotal folds encircling the penis ventrally, cryptorchidism and mild mental retardation. Endocrinological study showed only a reduction of Testosterone secretion attributable to malposition of the testis. The presence of minor abnormalities in the mother is compatible with a "X-linked" recessive transmission or with inheritance of an autosomal gene, dominant in males and recessive in females (sex controlled

No full textBecause insulin-dependent diabetes mellitus is associated with altered electrolyte metabolism and a derangement of the parathyroid hormone (PTH)-vitamin D endocrine system, we studied 23 children with diabetes (age 9.4 +/- 2.5 years) and found lower serum values for total and ionized calcium, magnesium, intact PTH, calcitriol, and osteocalcin than in age- and sex-matched control subjects. All patients were given magnesium orally (6 mg/kg daily of elemental magnesium) for up to 60 days. During treatment, serum magnesium, total and ionized calcium, intact PTH, calcitriol, and osteocalcin concentrations significantly increased, reaching control values. After a 3-day low-calcium diet, the patients had a significantly reduced DELTA-increment of PTH and calcitriol in comparison with values obtained during hypomagnesemia. After magnesium repletion, the DELTA-increments of both PTH and calcitriol, in response to the low-calcium diet, were not significantly different from control values. These data suggest that magnesium deficiency plays a pivotal role in altering mineral homeostasis in insulin-dependent diabetes mellitus
Tuning Intersection-Over-Union Algorithm to Enhance Tracking Performances
No full textIn computer vision, object tracking remains a pivotal challenge, significantly impacting the performance of various applications such as autonomous driving, surveillance, and robotics. The Intersection-Over-Union algorithm is a lightweight and efficient method for online multi-object tracking. This characteristic allows it to be deployed on low-performance devices, including edge devices and battery-powered devices such as unmanned aerial vehicles. Unfortunately, the performance of the algorithm depends on several parameters that, if not appropriately sized, can make it useless. This paper deeply characterizes these dependencies by means of a Monte Carlo exploration of the design space. As a result of the empirical experiments, an optimal combination of input parameters is proposed to maximally increase the performance without affecting the lightness of the algorithm
Estimation of renal function from body composition analysis and plasma creatinine in pediatric patients

Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
