Background. Previous studies have shown that the risk of major cardiovascular events at 1 year is less than 1% in patients with normal myocardial stress perfusion study results. However, the racial distribution of patients enrolled in these studies is not known. Hence, the prognostic value of normal stress perfusion study results in black...

Background. The present study was designed to investigate, in a rabbit model, the efficacy of topical application of a solution of hydrogen peroxide (H2O2) 8% + dimethyl sulphoxide (DMSO) 50% in order to reduce ischaemic failure in random skin flaps. Methods. Two parallel, cephalad-based para- midline random cutaneous flap (10x2.5 cm) were...

Objective. Indications for endoscopic transthoracic upper dorsal sympathectomy are axillary and palmar hyperhidrosis, upper extremities ischemia (due to, e.g., Raynaud's disease), and upper extremities causalgia. Methods. At present, this methodology relies on (at least) double trocar insertion (per side) and/or carbon dioxide insufflation....

Aim of this paper is to present a computer program able to provide objective and quantitative data useful to garantee the selection of the proper implant in order to obtain simmetry with the contralateral breast, in case of unilateral breast reconstruction by tissue expansion, especially for surgeons without experience or for occasional...

The aim of this study was to evaluate if it is possible to determine, by means of isoelectric focusing, an enzymic differentiation in human amniotic fluid, and if the onset of fetal cleft lip and palate is accompanied by a pathological enzymic differentiation pattern in amniotic fluid. From January 1993 to June 1996, amniotic fluid samples were...

Background. Aim of this paper is to describe a computer program which can provide objective and quantitative data useful for the selection of the proper implant in order to obtain the symmetry with the contralateral breast in case of unilateral breast reconstruction by tissue expansion, especially for the surgeon without experience or for the...

This study shows that topical applications of dimethyl sulfoxid (DMSO) 60% increase the benefits related to the use of intra-operating tissue expansion due to skin lesion excision. This phenomenon is explained by the strong collagen power of DMSO, which breaks both inter-molecular and intra-molecular links of collagen fibres with a possible...

The aim of the present study was to evaluate how much a relaxing incision of the galea aponeurotica affects the biomechanical properties of a scalp flap to quantify the surgery-related advantages provided by this procedure. Twenty scalp flaps, created by a reverse-Y incision down and through the galea aponeurotica together with undermining (in...

Background. The aim of this paper was to present a new technique, the H- shaped splint, for digital flexor tendon repair, aimed at enhancing the biomechanical properties of such repairs as related to resistance to both gap formation and repair failure. Methods. In order to evaluate the gap-formation and failure strengths of the described...

Background. This article describes an operative technique, based on the use of three galeal flaps anchoring, aimed at reducing the percentage of "stretchback" occurring after performing scalp reduction procedures. Methods. In 12 male patients undergoing a midline scalp reduction procedure, three rectangular galeal flaps, in direct continuity...

A correct and accurate preoperative planning is fundamental for reconstructive and plastic procedures in order to obtain functional and esthetic results. The aim of this study is to describe a prototype of a software dedicated to the visualization of a 3D model from one single patient. This kind of model, generated by the manipulation of MR...

The aim of this article is the evaluation of the topical application of a solution of hydrogen peroxide (H2O2) 8% and dimethyl sulphoxide (DMSO) 50% in order to reduce ischaemic failure in random skin flaps. This study was performed using a rabbit model. Two parallel, cephalad-based para-midline random cutaneous flap (10 cm × 2.5 cm) were...

Background. The aim of this study was to evaluate, in an in vitro model, the survival and growth rates of transversely sectioned human hair follicles to assess experimentally the efficacy of this approach as a future possible method for 'duplicating' available donor hair grafts in hair transplantation procedures. Methods. A total of 300 human...

Background. The aim of this study was to test the ex-vivo biomechanical properties of acutely expanded scalp flaps, in order to quantitatively assess the efficacy of acute scalp expansion. Methods. A total of 14 fresh male cadavers were used for the study. In each cadaver, a rectangular (4 × 10 cm), laterally-based flap was designed on each...

The aim of this paper was to present modifications of the conventional Kessler technique, the "wrap-core" suture, for digital flexor tendon repair, aimed at enhancing the biomechanical properties of such repairs as related to resistance to both gap formation and repair failure. Comparing (in an ex vivo study) the tensiometric properties...
