Arthroscopic repair of rotator cuff tears is now possible. By using the biomechanical principles of margin convergenceand the balance of force couples, even large cuff defects can be repaired. Suture anchors are particularly suitable for arthroscopic repairs, and a corkscrew anchor design lends itself to a trans-tendon approach 相似文献

Background. Topical anesthetics are widely used to diminish the sensation of pain from various medical cutaneous procedures. Any topical agent that reduces the desired effect has clinical ramifications.
Materials and Methods. Topical 6% benzocaine cream was applied to both inner forearms of five persons and covered with a bandage. One of the arms was additionally treated simultaneously with 5% benzoyl peroxide. The areas were tested with a pinprick examination every 10 minutes for the ensuing hour.
Results. There was an estimated 75% increased perception of pain on the forearm to which benzoyl peroxide was applied in consort with the topical anesthetic at all examination times.
Conclusions. Benzoyl peroxide chemically reacts with topical anesthetics such as tetracaine, procaine, pramoxine, prilocaine, and lidocaine, causing a significant reduction in their numbing effect. Clinically, make sure that the skin area to be topically anesthetized is devoid of any previous treatment with benzoyl peroxide or insist that the skin is thoroughly washed prior to application of the anesthetic.

The newly created position of clinical coordinator for the Center for Cranial Base Surgery at Presbyterian-University Hospital is detailed in this article. The position evolved in response to needs of this specialized center, because the complexities of cranial base tumors (CBTs) require optimal patient care be a collaborative effort. The clinical coordinator works with the neurosurgeon in all phases of treatment. From the preoperative visit, through admission and surgery, and then in postoperative care and follow-up, patient care is centered not only on the physical aspects inherent in surgery and recovery, but also on psychological support and attention which must be maintained throughout the patient's treatment course. In addition, the clinical coordinator has important input concerning research activities, particularly in clinical implementation of new therapies, as well as patient data management. Inservice education of other health professionals in their dealings with CBT patients further enhances quality of and continuity in patient care. Patient-care responsibilities as well as related research and training activities are discussed. 相似文献

The effects of unilateral pneumonectomy (PNX) on the net synthesis of right lung protein were investigated in vivo using three groups of rats with body weights (BW) ranging from 85 to 330 g. These data were compared to those from sham-operated and normal growing control animals. After PNX, both the 2-day lag prior to the compensatory increase in right lung mass (LW) and the subsequent rate of increase in LW and LW/BW ratio were independent of two-fold differences in the basal rate of lung growth. In all PNX groups, both right LW and LW/BW reached control values for both lungs, but in the older rats the time required for complete compensation was extended from 5 days to 12 days. The rate of net accumulation of right lung protein increased two-fold in the youngest PNX rats and 6 to 8-fold in the older animals, but when these changes were normalized to the protein content of the remaining tissue, the older rats appeared to respond to PNX less efficiently. Increased tissue levels of RNA and the resulting increased capacity of the lungs for protein synthesis could account for the accelerated rate of gain in right lung protein following PNX in both adult and young animals. 相似文献
