Free vascularized fascial flap in oral cavity reconstruction

Our experience with the free vascularized fascial flap based on the radial artery used for intraoral reconstruction is described. Thirteen patients underwent primary or secondary reconstruction following major resections for malignant disease. The osseofascial flap incorporating radial bone proved to be ideal when reconstruction of composite mandibular or maxillary defects was undertaken. The flaps rapidly underwent surface epithelialization, and submucosal fibrosis provided the ideal attached mucosal lining for prosthetic rehabilitation. © 1994 John Wiley & Sons, Inc.     

Expression profiling of metalloproteinases and inhibitors in cartilage

Objective   To profile the expression of all known members of the matrix metalloproteinase ( MMP ), a disintegrin and metalloproteinase with thrombospondin motifs ( ADAMTS ), and tissue inhibitor of metalloproteinases ( TIMP s) gene families in normal cartilage and that from patients with osteoarthritis (OA).
Methods   Human cartilage was obtained from femoral heads at joint replacement for either osteoarthritis or following fracture to the neck of femur. Total RNA was purified and expression of genes assayed using quantitative real-time PCR.
Results   Several members of the above gene families were regulated in OA. Genes increasing in expression in OA were: at P  < 0.001, MMP-13 , MMP-28 , ADAMTS-16 ; at P  < 0.01, MMP-9 , MMP-16 , ADAMTS-2 , ADAMTS-14 and at P  < 0.05, MMP-2 , TIMP-3 , ADAMTS-12 . Genes decreasing in expression in OA were: at P  < 0.001, MMP-1 , MMP-3 , ADAMTS-1 ; at P  < 0.01, MMP-10 , TIMP-1 , ADAMTS-9 and at P  < 0.05, TIMP-4 , ADAMTS-5 , ADAMTS-15 . Correlation analysis revealed that groups of genes across the gene families are co-expressed in cartilage.
Conclusion   This is the first comprehensive expression profile of all known MMP , ADAMTS and TIMP genes in cartilage. Patterns of expression provide a foundation on which to understand mechanisms of gene regulation in OA and potentially for refining the specificity of anti-proteolytic therapies.     

The management of bile duct stones.

Bile duct stones are almost always associated with gallbladder stones and coexist with gallbladder stones in approximately 10% of patients. The frequency of coexisting bile duct stones increases with advancing age. In patients with stones in both the gallbladder and bile duct, therapeutic options for the latter include laparoscopic or open exploration of the bile duct, and pre-operative and post-operative endoscopic sphincterotomy and stone extraction. Endoscopic sphincterotomy remains the treatment of choice for bile duct stones after cholecystectomy. However, management algorithms in individual institutions will be influenced by surgical and endoscopic expertise and by other factors such as overall costs. After surgical or endoscopic removal of bile duct stones, estimates of the lifetime risk of recurrent stones range from 5%-20%. Increased life expectancy and the apparent absence of simple preventative measures indicate that the burden of bile duct stones on health expenditure is likely to increase in many countries.     

Improved documentation of wound care with a structured encounter form in the pediatric emergency department.

OBJECTIVE: Accurate and complete documentation may enhance reimbursement and compliance with financial intermediary regulations, protect against litigation, and improve patient care. We measured the effect of introduction of a structured encounter form on the completeness of documentation of pediatric wound management in a teaching hospital. METHODS: The Children's Hospital Emergency Department introduced a structured encounter form for use in the documentation of wound care in place of the existing free-text dictation method. Attending physicians and trainees, all unaware of the study, had the option of using the form in place of free-text dictation for patients with lacerations requiring closure. We abstracted 100 consecutive free-text dictations from patients treated before the form's introduction. Following a 3-month run-in period, we abstracted 100 consecutive structured wound records. We compared the 2 chart types for completeness of documentation based on 20 predetermined criteria relevant to pediatric wound care. RESULTS: Overall completeness of documentation improved with structured forms (80% vs 68% for free text, P < .001), with significant improvements in 6 of 20 individual criteria. Trainees demonstrated improvement in documentation with the structured form, with the greatest improvements among senior-level residents. Documentation of the general physical examination worsened with structured charting. DISCUSSION: In an academic pediatric emergency department, the use of a structured complaint-specific form improved overall completeness of wound-care documentation. Structured encounter forms may provide for more standardized documentation for a variety of pediatric chief complaints, thereby facilitating communication and ultimately transition to template-driven systems in anticipation of an electronic medical record.     

The psychological and social characteristics of patients referred for NHS cosmetic surgery: quantifying clinical need.

PURPOSE: Elective cosmetic surgery is expanding in the UK in both the public and private sectors. Because resources are constrained, many cosmetic procedures are being excluded within the National Health Service. If guidelines on who can receive such surgery are to be evidence-based, information is needed about the level of dysfunction in patients referred for elective surgery and whether this is related to their degree of physical abnormality. METHOD: Consecutive patients referred to a regional plastic surgery and burns unit for assessment for elective cosmetic surgery completed standardised measures of physical and psychosocial dysfunction, and indicated their perception of the degree of their abnormality and their preoccupation with it. We distinguished between patients referred for physical reasons or appearance reasons only, and compared levels of physical and psychosocial dysfunction in each with published values for community and clinical samples. Surgeons indicated patients' degree of objective abnormality, and we identified the relationship of dysfunction with perceived and objective abnormality and preoccupation. RESULTS: Whether patients sought surgery for physical or appearance reasons, physical function was normal. Those seeking surgery for appearance reasons only had moderate psychosocial dysfunction, but were not as impaired as clinical groups with psychological problems. Patients seeking the correction of minor skin lesions for purely appearance reasons reported excellent physical and psychosocial function. Level of function was related (negatively) to patients' preoccupation with abnormality rather than to their perceived or objective abnormality. CONCLUSIONS: In general, patients referred for elective cosmetic surgery did not present with significant levels of dysfunction. Moreover, levels of functioning were related to preoccupation rather than to objective abnormality. Therefore, for most patients, whether surgical treatment is generally appropriate is questionable. Future guidelines must seek to identify the small minority who do have a clinical need for surgery.
