The Authors discuss the problems related to male infertility, pointing out their different clinical and therapeutical features. They stress the importance of plastic surgery in the treatment of disorders such as penile chordee, hypospadias as well as nervous and vascular lesions.
Acute normovolemic hemodilution (ANH) is indicated and useful in all procedures of plastic surgery in which great blood loss is expected. Here we present the advantages of ANH such as avoidance of incompatibility reaction, no risk of disease transmission, better microperfusion, economic and psychological advantages, and saving blood.
Balanitis xerotica obliterans, or kraurosis penis, is a chronic progressive scleroatrophic process of the penis, prepuce, and urethral meatus. This syndrome is due to lichen sclerosus et atrophicus of the genital region. We have observed 32 patients, whose ages ranged from 24 to 78, with different clinical and pathologic findings. Clinical symptomatology consisted of painful erection with secondary impotence, burning, itching, and urinary disorders. The treatment in the early stages is pharmacologic; stenosis of the meatus, phimosis, scar adhesions, fissures, and erosions of glans and prepuce prescribe a surgical treatment. We have performed modified circumcision, meatotomy and meatoplasty, removal of the scleroatrophic tract and subsequent grafting. The functional results were satisfactory.

Several techniques have been proposed for reconstruction of the breast after mastectomy. The authors present their experience with 19 patients; dermofat flaps were the preferred procedure. The authors discuss their technique of preparing and modeling the flaps, as well as some modifications and the possibility of using silicone prostheses. The limitations of the technique are reduced dimensions of the reconstructed breast, large and sometimes evident scars, and the difficulty or impossibility of performing the procedure on thin patients. The results are deemed positive, and the incidence of complications low. The authors consider the method a valid alternative to the use of prostheses in reconstruction after subcutaneous mastectomy.

The authors set out their therapeutic trend in the treatment of angioma and the criteria governing the use of the various therapies according to the type of dysplasia and its clinical course; they then report on the results obtained in a series of 400 cases. Only 22 cases with unfavourable trend (evolution of lesion) were observed, whereas the others exhibited spontaneous regression (85 cases), arrest of evolution (50 cases) or regression or cure (243 cases).

A clinical study was made of 14 cases of multiple symmetrical lipomata in two families. There were 7 female and 7 male patients. In one family the members affected were observed in four generations. The disease set in during the third or fourth decade of life. The lipomata ranged in size from that of a pea to that of a hen's egg. They were limited to the forearms and trunk were asymptomatic.
Recently ultrasound assisted liposuction (UAL) and pneumatic assisted liposuction (PAL) have been introduced as an attempt to improve the results and reduce the pitfalls of standard liposuction (SAL). Until now no studies comparing, at the same time, UAL, PAL, and SAL have been published. The aim of this study was to analyze these methods from the surgeon's point of view, focusing not only on aesthetic results but also on local and systemic trauma, efficacy, handling, and cost. Forty-five cosmetic patients affected by local lipodystrophy, divided into three equal groups, have undergone liposuction with the three above-mentioned techniques. Quantitative and qualitative analysis of lipoaspirates, together with blood chemistry, local and systemic complications, time to aspirate 100 cm3, distress, fatigue, and costs of the procedures, has been recorded. Our results showed bloodier lipoaspirates in SAL and a higher percentage of triglycerides in UAL lipoaspirates. Blood tests revealed a slight decrease in the postoperative Hb in SAL only. Early complications observed were four erythemas in PAL, three ecchymoses in SAL, and one long-lasting edema in UAL. Aesthetic results rated by independent viewers were similar for all methods. Efficacy was higher in the PAL group (4 min x 100 cm3 fat aspirated) than in SAL (7 min x 100 cm3 fat) and UAL (10 min x 100 cm3 fat). Surgeon's distress was higher in PAL than in SAL and UAL. Surgeon's fatigue was much lower in the PAL group than in the others. Costs expressed as multiples of 1 unit (1 unit = $500 U.S.) were highest for UAL, low for PAL, and lowest for SAL. In conclusion, PAL and UAL caused reduced vascular injury, UAL being more selective for adipocyte removal. Complications of UAL and PAL were mostly related to the longer learning curve of these methods. The UAL procedure was much more expensive than PAL and, especially, SAL. PAL proved to be a handy technique, with the most favorable cost/benefit ratio, and seems to be the best option for busy liposuction practices or fast office procedures, even though the choice of the ideal technique always depends on the surgeon's preference.
We report on the use of a modified Schiotz tonometer to evaluate the effects of therapies on burn scars. It is now possible to quantify the course of cicatrization with tonometry. Because tonometry affords a precise evaluation of burn scar diagnosis and prognosis, it is possible to avoid arbitrary clinical evaluation of the burn scarring process.
