Nephrogenic adenoma of bladder in immunosuppressed renal transplantation.

A case of nephrogenic adenoma is reported in an immunosuppressed renal transplant recipient. The nature of the lesion is discussed, and a possible relationship between benign tumors and impaired immunologic surveillance is considered.

Serum immunoglobulin levels in vasectomized men: preliminary report.

Seventy-five men undergoing vasectomy were tested by radial immunodiffusion assay prevasectomy and at 6 weeks and 3, 6, and 12 months postvasectomy for possible changes in serum immunoglobulin (Ig) levels. No significant changes occurred when the results were analyzed on a group basis per time period. However, when each individual's prevasectomy Ig level was considered as his norm, significant changes appeared to occur in serum IgG levels at 6 weeks, 6 months, and 12 months postvasectomy; in serum IgM levels at 6 weeks; but not, to date, in serum IgA levels. Seasonal, environmental, and infectious factors do not seem to be associated with the changes found. No significant seminal Ig changes have been demonstrated. Consideration of these findings and implications for possible immunopathology are briefly discussed.

Rhytidectomy.

The success of rhytidectomy depends on the selection of the patient, the technique and skill of the surgeon, and preparation of the patient prior to surgery. The patient must be made aware of what to expect before, during, and after the operation. Patients can expect to look presentable enough to appear in public in 2 to 3 weeks following the surgery. The final result will be apparent in from 6 to 8 weeks after surgery (Figs. 8-10).

Treatment of photoaging. Facial chemical peeling (phenol and trichloroacetic acid) and dermabrasion.

A complete armamentarium using phenol, trichloroacetic acid, and dermabrasion allows the physician to successfully treat a variety of difficult photoaged skin problems in a consistent fashion. These three techniques have their specific indications, and patient selection is the key to a successful outcome. Proper attention to technical detail will allow the physician to fine-tune technique to meet the individual's needs. It is important to realize that phenol, trichloroacetic acid, and dermabrasion are not exclusive of each other, but are additive in their value. As one becomes well versed in these differing treatment modalities, one can tailor these techniques to obtain consistent results according to the needs and desires of the patient.

What's new in aesthetic surgery.

This article describes new trends, techniques, and instrumentation in aesthetic surgery. Advances in our understanding of anatomy and the changes that come about with intrinsic and extrinsic factors are discussed. Specifically, anatomic approaches to rhytidectomy, the preservation of lid shape in blepharoplasty, and CO2 facial resurfacing are highlighted. Body contouring surgical techniques, including minimal scar breast reductions, endoscopic-assisted augmentation mammoplasty, and superficial liposuction, are reviewed.

Extended SMAS dissection as an approach to midface rejuvenation.

The objective in rhytidectomy is to rejuvenate and improve facial appearance. To obtain consistent results, facelifting should be approached not just as a tightening or lifting procedure but also as a reconstructive procedure, reversing the anatomic changes that occur in aging. The ability to bring aesthetic harmony back into the aging face requires the blending of surgical technique, anatomic knowledge, and artistic sensitivity to individualize the surgical approach for a given patient. To obtain surgical rejuvenation while minimizing signs of surgical distortion remains the ultimate goal of our facelifting procedures.

Midazolam (Versed) in ambulatory surgery.

Midazolam is a very useful drug in outpatient aesthetic surgery. Its principal advantages are (1) short duration of action (a half-life of 2.3 hours), (2) painless injection, (3) no incidence of postoperative phlebitis (as compared with diazepam), and (4) a high degree of safety and effectiveness. Since one of the main objectives in outpatient surgery is to have the patient recover as quickly as possible and be discharged without any significant drug hangover, we recommend the incorporation of midazolam into the armamentarium of the aesthetic surgeon. Subsequent to the presentation of this paper (Twentieth Annual Meeting of the American Society for Aesthetic Plastic Surgery, in Los Angeles, California, March 23, 1987), we have administered midazolam to an additional 400 patients undergoing outpatient surgery and no apnea has occurred requiring an airway or supportive respiratory measures.

Rhytidectomy: a statistical analysis.

A statistical analysis of 1,500 consecutive rhytidectomies is presented. In rhytidectomy, complications occur in a significant percentage of the operations. The plastic surgeon must be aware of the incidence and significance of these complications, and also he must know how to avoid or manage them.

Upper lid blepharoplasty.

We reviewed, retrospectively, our upper lid blepharoplasties to critically compare our own postoperative results after (1) conventional blepharoplasty, or (2) fixation of the levator aponeurosis to the lower margin of the orbicularis, or (3) fixation of the levator to the lower margins of the orbicularis and the skin. We found no demonstrable difference in our results with these 3 techniques. It is our opinion that the standard conventional blepharoplasty (including excision of a strip of orbicularis muscle) is preferable for use in most caucasian eyelids. The results are as good, it is simple, and it is less likely to cause problems.

Long-term histologic follow-up of phenol face peels.

Deep phenol peels were done on 11 middle-aged white women with severe actinic damage. Subsequently, face lifts were carried out after periods of 1.5 to 20 years. This made it possible to obtain a full-thickness specimen extending several centimeters on either side of the border between peeled and unpeeled skin. In contrast to the markedly abnormal elastotic appearance of unpeeled skin, a new band of connective tissue 2 to 3 mm in width was laid down in the subepidermal region. Fine elastic fibers formed a dense network in the band of regenerated collagen. The disarray and cytologic abnormalities of sun-damaged epidermis were also largely corrected. Melanocytes were not eliminated, but melanin synthesis was evidently impaired, accounting for the bleaching effects. The effects of a phenol peel are very long lasting and adequately account for the effacement of wrinkles and obliteration of actinic keratoses, mottling, and freckling.

The relationship of the superficial and deep facial fascias: relevance to rhytidectomy and aging.

Controversy persists regarding the relationship of the superficial facial fascia (SMAS) to the mimetic muscles, deep facial fascia, and underlying facial nerve branches. Using fresh cadaver dissection, and supplemented by several hundred intraoperative dissections, we studied facial soft-tissue anatomy. The facial soft-tissue architecture can be described as being arranged in a series of concentric layers: skin, subcutaneous fat, superficial fascia, mimetic muscle, deep facial fascia (parotidomasseteric fascia), and the plane containing the facial nerve, parotid duct, and buccal fat pad. The anatomic relationships existing within the facial soft-tissue layers are (1) the superficial facial fascia invests the superficially situated mimetic muscles (platysma, orbicularis oculi, and zygomaticus major and minor); (2) the deep facial fascia represents a continuation of the deep cervical fascia cephalad into the face, the importance of which lies in the fact that the facial nerve branches within the cheek lie deep to this deep fascial layer; and (3) two types of relationships exist between the superficial and deep facial fascias: In some regions of the face, these fascial planes are separated by an areolar plane, and in other regions of the face, the superficial and deep fascia are intimately adherent to one another through a series of dense fibrous attachments. The layers of the facial soft tissue are supported in normal anatomic position by a series of retaining ligaments that run from deep, fixed facial structures to the overlying dermis. Two types of retaining ligaments are noted as defined by their origin, either from bone or from other fixed structures within the face.(ABSTRACT TRUNCATED AT 250 WORDS)

Operations postponed by anaesthetists: a prospective study.

A prospective study was carried out in one District Health Authority over a twelve month period to investigate the principal reasons for the postponement of operations on the advice of anaesthetic staff. A mean of 1.4% of all cases listed for general anaesthesia were postponed. The clinical indications for this are described and possible methods for reducing this figure are discussed.
