The vision of haptics tunes the somatosensory threshold.

The interaction between different sensory modalities represents a crucial issue in the neuroscience of consciousness: when the processing of one modality is deficient, the concomitant presentation of stimuli of other spared modalities may sustain the restoration of the damaged sensory functions. In this regard, visual enhancement of touch may represent a viable tool in rehabilitating tactile disorders, yet the specific visual features mostly modulating the somatosensory experience remain unsettled. In this study, healthy subjects underwent a tactile detection task during the observation of videos displaying different contents, including static gratings, meaningless motions and natural or point-lights reach-to-grasp-and-manipulate actions.

Duration of mechanical ventilation after craniosynostosis repair reduces over time.

Background: Pediatric craniosynostosis repair (CR) involves wide scalp dissections with multiple osteotomies and has been associated with significant morbidity. The aim of this study was to document the impact of perioperative complications on prolonged mechanical ventilation after CR.

Methods: Data were collected from the anesthesia records, Pediatric Intensive Care Unit (PICU) progress notes and discharge summaries.

Designs for correction and camouflage of bilateral clefts of the lip and palate.

The bilateral cleft anomaly is difficult to correct and camouflage because of the double lack of many important landmarks and the shortness of skin in the midvertical plane. A possible solution in patients who have some columella or in those of races not needing a long columella is the strap flap advancement of the nostril sills and alar bases. In all other cases, the forked flap is the method of choice for adequate correction and camouflage of the bilateral cleft lip-nose deformity.

Secondary aldosteronism documented by plasma renin and aldosterone circadian rhythm in subjects with kidney or heart transplantation.

The circadian rhythm (CR) of plasma renin activity (PRA), plasma aldosterone (PA), and plasma cortisol (PC) was investigated in 8 patients with kidney transplantation, and in 10 patients with heart transplantation. Ten clinically healthy subjects were studied as controls. The transplanted patients were all under cyclosporine treatment associated with prednisone (PDN).

[Circadian rhythm of the renin-angiotensin-aldosterone system in subjects with kidney and heart transplants].

The present investigation evaluates the circadian rhythm of renin-angiotensin-aldosterone system (RAAS) in subjects with kidney (KTS) or heart (HTS) transplantation undergoing conventional therapy with prednisone and cyclosporine. RAAS circadian rhythmicity has been compared with the circadian cycle of cortisol as a marker rhythm. The chronobiological exploration has been performed by measuring the circulating levels of plasma renin activity (PRA), plasma aldosterone (PA), and serum angiotensin-converting-enzyme (SACE) and plasma cortisol (PC) in serial samplings collected six times over a 24-h span.

The role of indium-111 antimyosin (Fab) imaging as a noninvasive surveillance method of human heart transplant rejection.

The identification of rejection after heart transplantation in patients receiving cyclosporine immunosuppressive therapy requires the endomyocardial biopsy, an invasive method associated with a finite morbidity. To evaluate the role of indium-111 antimyosin (Fab) scintigraphy as a noninvasive surveillance method of heart transplant rejection, the Fab fragment of murine monoclonal antimyosin antibodies labeled with indium-111 was administered intravenously in 30 scintigraphic studies to 10 consecutive heart transplant recipients. Endomyocardial biopsy specimens were obtained 72 hours after each scintigraphic study.

[24-hour behavior of T-lymphocyte subpopulations in patients with stable heart transplants receiving cyclosporin therapy].

In 10 heart transplanted subjects (HTS) undergoing conventional immunosuppressive cyclosporine therapy, in comparison with 10 normal subjects, the 24 hour patterns of T lymphocyte subpopulations, namely, OKT3 (total T lymphocytes), OKT4 (helper lymphocytes) and OKT8 (cytotoxic or suppressor) in relation to the circadian rhythms for plasma cortisol (marker rhythm) and to circulating levels of cyclosporine were studied. From the collected data, it can be deduced that the OKT3, OKT4, OKT8 subpopulations and the plasma cortisol level show 24-hour non-periodic variations. The lymphocyte subpopulations show a negative correlation with circulating levels of cyclosporine.
