摘要:

Patients with subcutaneously placed silicone gel prostheses, for reconstruction after subcutaneous mastectomies, often complain of cold breasts as well as of slow regaining of warmth, after cooling. We have used thermography in 7 such women and in 7 healthy women of the same age group as controls. Thermography has also been used in 3 women after repositioning of the subcutaneously placed prostheses to a submuscular position in order to study any possible changes in temperature. In 2 cases thermography also was found to aid in the diagnosis of a suspected subcutaneous displacement of a submuscular prosthesis; the technique has an advantage over mammographic examination, since thermography is a simple, less expensive, and safer method.

摘要:

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.

摘要:

This article discusses the use of a permanent saline-filled expander for breast reconstruction incorporating on the anterior surface a filler valve that can be located by nonoperative means. The self-sealing filler valve has a well-marked design that is particularly amenable to ultrasound detection. This results in the capacity to inflate or deflate the prosthesis at will. Sixty patients were operated on and 123 submuscular custom-made prosthetic expanders were implanted. Seventy-four percutaneous volumetric changes were performed without significant complications. Follow-up studies for more than 6 years are presented. The primary advantage of this prosthesis is its capability for percutaneous access under local anesthetic to produce volumetric changes. The prosthesis is permanent and does not have to be replaced as normal tissue expanders do. Only 1 operation is necessary. In addition, capsule contracture and spontaneous deflation rates are within an acceptable range.

摘要:

This study has provided baseline data of a quantitative neurophysiological appraisal of normal breast sensibility using our current understanding of cutaneous mechanoreceptive function. Test variables, including pressure, low- and high-frequency vibration, static and moving two-point discrimination, temperature, nipple erectibility, and pain, were evaluated in 11 normal volunteers using different coordinates over the nipple, areola, and body of the breast. Definite patterns were established so that the breast could be subdivided into distinct cutaneous areas with differing mechanoreceptive characteristics. The future aim is to broaden the scope of this study with preoperative evaluations in our clinical patients so that appropriate recommendations for future reconstructive breast procedures can be made.

摘要:

Sixty-six cases of cytostatic extravasation referred to a plastic surgery department between 1977 and mid-1985 are discussed. Doxorubicin was the most common drug involved, but a number of other drugs also caused lesions requiring surgical intervention. Operative treatment, consisting of excision of drug-infiltrated tissue followed by skin transplantation, was performed in half the patients. Significant residual damage was seen in 12 patients who had all received the drug at the elbow joint, wrist, or back of the hand. Fourteen patients were operated on late in the course of the disease, on average 10 weeks after the accident because of delayed referral. In 1983 prophylaxis was undertaken and first-aid treatment was administered, consisting of aspiration via the administration catheter. The nature of patient referrals then improved considerably. It is recommended that cytostatic treatment be given at the ante-brachium, if possible, and that aspiration be attempted promptly after an accident. Manifest lesions should be operated on early, i.e., within the first week. The indication for early operation is particularly strong if a highly irritative drug has been deposited in a critical region and has caused a severe local reaction.

摘要:

Based on a study of the literature and our own experience treating fisherman poisoned fry mustard gas, this article outlines the clinical effects, and toxicological and mutagenic properties of the agent. Mustards are very persistent chemical agents that easily penetrate clothing. Mustard gas usually causes clinical symptoms after the liquid penetrates the skin or the vapor is inhaled. Skin lesions are similar to first- or second-degree burns and usually heal spontaneously in 4 to 6 weeks. Eye symptoms are photophobia and reduced vision. Following inhalation of the agent, pulmonary edema and long-term dyspnea may be seen. As mustard gas is an alkyldting substance, it is conceivable that the risk of developing cancer may be increased, as observed in people who were involved with the production of mustard gas and in animals exposed to the gas. Also, transient significantly increased sister chromatid exchange rates have been found in fishermen exposed to mustard gas.Patients exposed to mustard gas must be treated immediately after exposure. Treatment should consist of cleaning of the exposed skin and clothes with an antigas powder and water and soap. The skin lesions should be treated as bums. Eye lesions and respiratory problems should be treated symptomatically.

摘要:

Dupuytren's disease in blacks is believed to be rare. Our recent experience with the disease at the John Cochran Veterans Administration Hospital in St Louis is described, including 2 black patients suffering from the condition. The literature is reviewed and some aspects of pathogenesis are discussed. It is our belief that Dupuytren's disease is more common in blacks than previously reported.

摘要:

A cross-facial nerve graft connected to buccal branches of the healthy facial nerve may carry axons destined for the orbicularis oris muscle as well as axons destined for elevators and abductors of the comer of the mouth. If this nerve graft innervates a pedicled or free muscle flap, contractions of the flap or part of it will also occur when the patient purses his lips. This results in immobilization of the comer of the mouth. On the other hand, smiling may lead to simultaneous contraction of other erroneously reinnervated muscle fibers, equally immobilizing the comer of the mouth. Electromyography in these cases shows well-reinnervated musculature. The only solution to prevent this so-called static syndrome is to transplant smaller nerves connected at more peripheral levels to smaller facial nerve branches with more specific functions.

摘要:

A study of 11 strips of curved cartilage harvested from 11 pigs' ears was undertaken to compare quantitatively the forces required to bend the strips before and after modification. The results show no statistical difference between the intact curvature and curvature produced when skin and perichondrium were resutured over 4 full-thickness, cartilaginous crosscuts. These in vitro findings suggest that, when one attempts to modify the shape of curved cartilage, lasting results may be obtained by shortening the convex surface length using a wedge excision method. The perichondrium is incised on the concave surface or the surface that will become longer with cartilage scoring, such as in otoplasty. If the cartilage surface will require elongation for ultimate straightening, the perichondrium as well as the cartilage must be incised.
