PurposeA vertical posture makes it difficult to maintain balance especially in the elderly. Loss of balance leads to falls and injuries. In the present study, we evaluated whether balance maintenance can be improved with the use of stochastic resonance whole body vibration (SR-WBV).MethodsAn examination of balance, involving 187 women aged 19–74 years, was conducted using double-plate posturography pre and post SR-WBV. The SR-WBV trainings were performed using the SRT Zeptor Medical-plus noise device. The entire study lasted 6 weeks, with a total of 12 training sessions, each consisting of nine 45 second series, with a 45 second pause between them.ResultsPost SR-WBV there was a reduction in the value of: the resultant mean velocity (MV) of the movement of COP (centre of pressure) for both lower limbs (B) and in the right lower limb (R) during the test with eyes closed (EC), the mean velocity and mean amplitude (MA) of the movement of COP along the x-axis (ML) of the left lower limb (L) during the test with eyes open (EO) and closed and some additional parameters. Negative correlations between age/index of improvement of MV-EC-B, MV-EC-L and MVML-EC-L, and BMI/index of improvement of MV-EC-B, MVML-EC-B appeared. Height correlated positively with the index of improvement of MV-EC-B and MVML-EC-B.ConclusionsAs a result of SR-WBV, the left leg is more stable along the x-axis and the disproportion between the stability of both legs is reduced. Consequently, body stability is higher. The SR-WBV is more effective in younger, taller and slimmer women. SR-WBV parameters should be optimized so that the training is more beneficial for elderly and shorter women, and for women with a higher BMI.
The aim of study was to prove that combination of visual surgical planning (VSP) together with cone beam computed tomography (CBCT) is an optimal technique in fibular free flap reconstructions after complex tumor resections in the head and neck region and that it results in better functional and aesthetic outcome. Subjects and methods: 6 patients (3 females, 3 males) with head and neck tumors were included in the study. The region concerned midface in 2 cases and mandible in 4 patients. On the basis of computed tomography of the head, fibular free flap (FFF) reconstruction was planned with the VSP technique. 3D-printed models were prepared. At the beginning of the operation and few minutes after the reconstruction an xCAT CBCT by XORAN was performed. Minor corrections of the angles of the reconstructed bony parts were made where needed. The time of the operation was assessed for each case. Functional and cosmetic results were evaluated in 1-year follow up. Results: The average time of operation was 6 hours 48 minutes, which was app.1hour 40 minutes less than standard reconstructive surgery. Functional recovery was achieved in all patients. Aesthetic result was unsatisfactory for 2 patients due to insufficient soft tissue masses of the FFF. Conclusions: The authors claim that intraoperative CBCT imaging, regardless the cost, improves accuracy of aesthetic outcome of the reconstructive surgeries based on VSP, especially in the region of midface and mandible. Further studies on larger amount of subjects are required.
Background: It has been suggested that applying the negative pressure wound therapy (NPWT) to a closedsurgical incision may hasten the healing of the incision and decrease the incidence of wound healing complications. The goal of this study is to present the new idea of a simple, self-made, low-cost wound vacuum dressing for closed-incision NPWT that may become an alternative to currently manufactured medicalindustry products.Method: We designed a simple dressing for closed-incision NPWT from gauze pads, polyurethane adhesive film, stoma paste, and a drain tube. Negative pressure was created using a standard 50 ml syringe connected to the drain. First, the dressing was applied to the wound model and on the healthy volunteer. Finally, the dressing was applied to 10 patients after low anterior rectal resection. The vacuum dressing was left in place for 3 days, then changed and placed once more for the next 3 days.Results: We did not observe any adverse effects associatedwith the dressing. All postoperative wounds healed properly. 18 out of 20 dressings were still air-tight 72h post-placement.Conclusions: This simple, self-made dressing for NPWT is safe and effective and may decrease the wound infection rate. However future studies are needed to confirm that hypothesis.
