Background: The free split latissimus dorsi flap for lower-extremity reconstruction has some advantages over the traditional latissimus dorsi flap. The flap is harvested with the patient in the supine position and is associated with minimal morbidity as the function of the remaining latissimus dorsi muscle is preserved through the posterior division of the thoracodorsal nerve. Methods: A consecutive single-surgeon 5-year series of free split latissimus dorsi muscle flaps for lower-extremity reconstruction (n = 42) was evaluated. Donor site morbidity was evaluated through assessment of the strength of the remaining latissimus dorsi at least 1 month after surgery. Shoulder function was evaluated postoperatively using the Disabilities of the Arm, Shoulder and Hand (DASH) score, American Shoulder and Elbow Surgeons (ASES) score, and Shoulder Pain and Disability Index (SPADI). Results: The mean age of the 42 patients was 40.7 years. The mean length and width of the flaps were 17.9 cm and 8.6 cm. The majority (71%) of the wounds were due to acute trauma. Of the 42 flap procedures performed, 95% (40) were successful. Assessment of remaining latissimus dorsi strength at least 1 month postoperatively, during 3 activities, showed a Medical Research Council (MRC) grade of 5 in all patients. The mean and median scores were 6.4 and 0 according to the DASH, 6.0/6.4 and 0/0 on the SPADI pain/disability scales, and 90.7 and 100 on the ASES. Conclusions: The free split latissimus dorsi flap is a large reliable muscle flap with negligible donor site morbidity that is particularly advantageous for lower-extremity resurfacing following trauma.

We reviewed our institution's experience with 2 common breast reduction techniques. Better scarring was associated with inverted T scar pattern versus vertical pattern. Additionally, rather than pedicle type or skin excision pattern, patient age and weight of tissue resected were the most important contributors to an aesthetically optimal outcome. This study suggests that a single superlative technique does not exist. Rather, inherent patient characteristics are most important in provision of the best aesthetic outcome.

Correlation of properties of common carbon fiber precursor materials, polyacrylonitrile (PAN) and pitch, with kinetics and sensitivity of microdisk electrodes, PAN T650, PAN HCB and Pitch P25, nanostructured by an electrochemical etching method was tested. Sensitivity of PAN electrodes is higher but kinetics are slower than at pitch electrodes due to more defects in PAN. Because of more surface oxides at PAN T650 adsorption of dopamine is greater than at PAN HCB electrodes but for uric acid adsorption is greater at PAN HCB. Uric acid sensitivity is related to high conductivity of PAN fibers, with an inverse relationship observed for dopamine.

The use of preoperative chemoprophylaxis in patients undergoing abdominoplasty can be done without an increase in bleeding complications or overall complication rate. Furthermore, enoxaparin can also be used preoperatively and continued for 2 more days during the period of time of maximum immobility with easy administration for outpatients via use of a prescription home use kit.
