Effects of various prostaglandin synthesis inhibitors on the tone of the lower oesophageal sphincter in man.

The role of endogenous prostaglandins in the modulation of lower oesophageal sphincter (LES) function has been assessed by giving three structurally unrelated cyclooxygenase inhibitors and monitoring their acute effects on LES tonus and platelet thromboxane (TX) B2 production in 20 healthy volunteers. In a double-blind, placebo-controlled, cross-over study, IV injection of soluble salts of acetylsalicylic acid and indomethacin elicited a transient increase in LES tonus of approximately 50% over baseline. A similar pattern was observed after the rectal administration of indomethacin. In contrast, indoprofen had no measurable effect on LES tones, despite comparable inhibition of platelet cyclooxygenase activity. This may have been due to the markedly different tissue distribution of the drug. The results suggest that endogenous prostaglandins physiologically exert an inhibitory influence on LES function.

Polyurethane-covered mammary implants: a 12-year experience.

Polyurethane-covered mammary implants are the implants of choice in aesthetic and reconstructive mammary surgery. These implants give very good results in regard to breast contour and consistency, and have a very low complication rate. We present our 12-year experience using polyurethane-covered prostheses. We place the implant mostly in the subglandular or subcutaneous site, and their capsular contracture rate is extremely low (3.3%). Based on our experience, we also review the other complications and side effects occurring with polyurethane prostheses and discuss them in detail.

Treatment of angiomas with sclerosing injection of hydroxypolyethoxydodecan.

The authors discuss the indications for hydroxypolyethoxydodecan in the sclerosing treatment of angiomas, with particular reference to cavernous, venous, and evolutive angiomas (ie, immature angiomas that fail to involute by eight to ten months). Moreover, the sclerosing agent may be employed, in connection with embolization and subsequent surgery, in arteriovenous angiomas with a relevant cutaneous-subcutaneous development. The authors have successfully used the "interstitial" sclerosing technique, according to Andrews' method. This technique involves interstitial injections to obtain the sclerosis of the thin threads of fibrous tissue stroma between the blood vessels. The sclerosing therapy may cause the complete regression of "low flow" angiomas or, at least, a partial reduction that simplifies the ensuing surgical excision. In the case of partial regression of the angioma obtained with the sclerosing therapy, the surgery of the remaining angioma causes a lesser degree of bleeding (especially in areas that do not particularly lend themselves to surgical exploration, ie, the oral cavity); an increased reliability in the radicality of the intervention (due also to the reduced size of the lesion); and better results from an aesthetic-functional point of view.

Subdermal liposuction.

Liposuction is a widely used technique today and indications are that it is becoming even more popular due to new technical refinements. The use of cannulae with a smaller diameter allows suction of the fat immediately under the dermis. The cannula we use to perform this new kind of fat suction is straight and has an external diameter of less than 2 mm. This cannula, the so-called Mercedes cannula, has a bullet tip and a three-hole head. Moreover, the holes are not round but are slit-shaped and oriented in the same plane at 120 degrees. This cannula is specifically designed to produce less trauma. The cannula with one downward-facing orifice is not suitable for suction of the subdermal layer and an upward-facing orifice would be too traumatic. The advantage of this new technique, apart from the possibility of treating patients with very slight adiposity, is to allow an effective skin retraction. When a large amount of fat has already been aspirated, residual deformities can occur. These skin irregularities represent the lack of an effective cutaneous retraction mostly due to the permanence of the subdermal fat. In fact, the presence of a thick subdermal adipose layer decreases the possibility of skin retraction. Therefore, indications for liposuction of the subdermal fat are mainly the slight adiposities and the remnant deformities of a previous liposuction operation. Moreover, this technique is applied to every lipoplasty whenever better skin retraction is needed.

Preoperative breast marking in reduction mammaplasty.

A simple method of preoperative marking for reduction mammaplasty is described. This method may be used in macromastias when the technique chosen implies a postoperative scar with the shape of an inverted T. The marking sequence follows standard steps, but the drawing is always different because it is a consequence of the shape of the breast. This marking method reduces the chance of making mistakes due to excessive personal evaluations or to the use of standard drawing patterns that may be not suitable for all breast shapes.

Immature angiomas: the importance of the Doppler exam in diagnosis and prognosis.

Immature angiomas are vascular hamartomatous malformations but clearly different from all other vascular, capillary, venous, arteriovenous, and lymphatic malformations, which, normally present at birth and established from a cellular viewpoint, grow because of the effect of hemodynamic stimuli and present no tendency toward spontaneous regression. The difference between immature angiomas and other hemangiomas has been demonstrated by investigations into cell dynamics. To facilitate a differentiated diagnosis and prognosis, the hemodynamics of the angiomas were studied with the Doppler flowmeter. The use of noninvasive techniques, such as those introduced by the Doppler flowmeter, permit a technical alternative and/or integration, giving results of equal relevance and importance, as well as the advantages of a more accessible and less expensive methodology.
