Thirty-nine patients underwent reconstruction of composite mandibular defects following resection for squamous cell carcinoma. Thirty-four underwent immediate reconstruction, while 5 were reconstructed secondarily. Twenty-one received soft-tissue reconstruction only with a pectoralis major myocutaneous flap, 14 underwent osteocutaneous free-tissue transfer, and 4 received a reconstruction plate with free-tissue transfer for soft-tissue coverage. The mandibular defects in the pectoralis major myocutaneous flap group tended to be posterolateral, while free-tissue transfer defects were more severe, usually involving the anterior mandible. Length of surgery and duration of intensive care unit care were significantly longer for free-tissue transfer patients, while flap complications were more common in the pectoralis major myocutaneous flap patients. Facial appearance scores were higher for the free-tissue transfer group by both patient and physician assessment. Social function, speech, and oral function did not differ significantly. Patients reconstructed secondarily with free-tissue transfer reported significant improvement in appearance, oral continence, and social function, with little change in speech intelligibility, deglutition, or diet tolerance. The cost of the main hospitalization was significantly higher in the free-tissue transfer group than in the pectoralis major myocutaneous flap group, although when the costs of subsequent hospitalizations are included, the difference in total cost narrows. Despite more adverse defects, free-tissue transfer provided more predictable aesthetic results and expeditious return to normal social function than did pectoralis major myocutaneous flap reconstruction. The fiscal impact of these complex reconstructions is, however, significant. Cost-containment issues are presented and recommendations are made

Rare individuals have been multiply exposed to HIV-1 but remain uninfected. The CD4+ T-cells of two of these individuals, designated EU2 and EU3, are highly resistant in vitro to the entry of primary macrophagetropic virus but are readily infectable with transformed T-cell line adapted viruses. We report here on the genetic basis of this resistance. We found that EU2 and EU3 have a homozygous defect in CKR-5, the gene encoding the recently described coreceptor for primary HIV-1 isolates. These individuals appear to have inherited a defective CKR-5 allele that contains an internal 32 base pair deletion. The encoded protein is severely truncated and cannot be detected at the cell surface. Surprisingly, this defect has no obvious phenotype in the affected individuals. Thus, a CKR-5 allele present in the human population appears to protect homozygous individuals from sexual transmission of HIV-1. Heterozygous individuals are quite common (approximately 20%) in some populations. These findings indicate the importance of CKR-5 in HIV-1 transmission and suggest that targeting the HIV-1-CKR-5 interaction may provide a means of preventing or slowing disease progression

In an attempt to obtain objective analysis of outcome in reduction mammaplasty patients, a retrospective study was done for women having elective bilateral reduction mammaplasty. Participants were chosen from a pool of over 200 consecutive reduction mammaplasty patients at the University of Missouri-Columbia. Of those eligible for inclusion, 72 met the criteria and were available for long-term follow-up. These patients answered a panel of questions regarding weight change, brassiere size, exercise, activity level, symptoms, and a personal appraisal of appearance. Statistical analysis was done to evaluate the change in each variable in relationship to the time of surgery, i.e., before surgery, 6 months after surgery, and at the present time. The findings revealed a significant stable reduction of breast mass. The women reported a significant reduction of symptoms that had been associated with their macromastia. They also reported a significant increase in exercise and other physical and social activities

The purpose of this article is to report how a group of 391 well-educated, White, midwestern American married fathers of young adolescents (11 to 14 years) described their perceptions of how they were raised. The question 'Describe how your parents parented you' was asked as part of a larger quasi-experimental study to test the outcomes of communication skills training among a sample of families in a community. The fathers' short-answer descriptions were succinct yet substantive. Using content analysis procedures, 6 themes were identified. Four reflected the men's perceptions of specific strategies used by their parents. The themes were labeled establishing boundaries, parental presence, adhering to guidelines, and communication techniques. A 5th theme, labeled family size, indicated that some men perceived that the structure influenced how they were parented. The 6th theme, evaluation of their parents' parenting, encompassed the men's opinions of how successful they perceived their parents were at raising them. The men's perceptions are discussed within the context of fathering roles. The themes are offered as a framework to define parenting, and implications for nursing practice and research are proposed

One of the most unsettling sequela of facial paralysis (FP) is the loss of the blink reflex, leading to both a functional and aesthetic deformity. A successful method of treating FP and, in particular, loss of eye-sphincter function, is the use of the cross-facial nerve graft (CFNG) to reinnervate the previously denervated orbicularis oculi muscle. The present study examined the histomorphometric aspects of the entire CFNG, with respect to axon diameter and myelin area. The axon profile of the CFNG had a positive correlation with motor end-plate counts and electrophysiologic recordings. These results should help in further understanding the number of motor axons needed to restore adequate function to the paralyzed eye sphincter, and establish more rational reconstructive procedures

The salvage rate of degloved amputation of the fingers is as low as 50%. This case report consists of a multiple-finger degloving amputation characterized by intact tendons, pulleys, and bone, but avulsed neurovascular bundles. After replantation, the range of motion of the fingers was nearly full. Protective-to-light touch sensation was obtained with transpositional digital nerve transfers. Grasp strength was 80% that of the uninjured side. In addition to good functional recovery, the aesthetic appearance obtained by replantation of the degloved skin was far better than that obtained by other reconstruction methods. A first web space flap was used to release a flexion contracture of the proximal interphalangeal joint of the middle finger
