Using high-voltage electrical stimulation in the treatment of recalcitrant pressure ulcers: results of a randomized, controlled clinical study .

 The use of electrical stimulation has been studied in a variety of wounds emphasizing different variables with regard to provision of therapy. The purpose of this prospective, randomized, controlled clinical study was to evaluate the effect of high-voltage electrical stimulation (HVES) on nonhealing, lower-extremity, Stage II and Stage III pressure ulcers. Patients admitted for care and eligible to participate in the study received standard supportive care and topical treatments covered with wet-to-moist dressings. Patients assigned to the treatment arm of the study also received HVES (100 V; 100 µs; 100 Hz) continuously for 50 minutes once daily, five times per week. Patients were followed until healing for a maximum of 6 weeks. Wound tracings and measurements were obtained weekly. Over a 4-year period, 26 patients were enrolled in the treatment and 24 in the control group. Ulcers had existed for an average of 3.17 and 2.83 months in the treatment and control groups, respectively. Most were classified as Stage II (17 in the treatment and 16 in the control group) with an average baseline size of 4.54 cm2 and 3.97 cm2, respectively. Wound areas and linear measurements decreased significantly in both groups (P <0.05), but increases in granulation tissue were significant in the treatment group only (P = 0.006). Wound area, linear measurement, wound volume, and granulation tissue changes were statistically significantly greater in the treatment than in the control group starting in the second week of treatment. Week 6 surface area change was 88.9% (SD 14) in the treatment and 44.4% (SD 63.1) in the control group (P = 0.00003). Correlation coefficients between changes in wound surface area, longest length, and longest width were R = 0.96 and R = 0.98 in the treatment and R = 0.94 and R = 0.89 in the control group. HVES improved the healing rate of recalcitrant Stage II and Stage III pressure ulcers. Research to compare the effectiveness of using cathodic and anodal stimulation combined or alone and to determine the optimal duration of these two types of electrical stimulation is warranted.

[The algorithm of physiotherapeutic procedures in patients after total cementless joint arthroplastics]. / Algorytm postepowania fizjoterapeutycznego u pacjentów po totalnej bezcementowej alloplastyce stawu skokowo-goleniowego.

The aim of this study is to present the physiotherapeutic procedure in patients after total cementless ankle atrhroplastics. It was introduced thus far methods and resources in the way of physics and kinesitherapy, how also methods in physical medicine, which there are introduced to numerous department of medicine also in orthopedics. From reason of small number of reports, the authors present in this work current dates of relate in physiotherapeutic procedure before and after cementless ankle arthroplasty, which profitably influence and show the characteristic improvement of local and general state in patient. In spite of existing limitations the introduced plan with patients after total cementless joint arthroplasty should facilitate taking of sure solutions and workings persons with this patients.

[Estimation of magnetic radiation effects on leucocytes]. / Ocena skutków oddzialywania promieniowania magnetycznego na leukocyty.

A lot of epidemiological and experimental research has been done recently into effects of magnetic fields (MF) on live bodies. Among others, the effects of MF on human immunological system are studied. Primary cells of the immunological system are leucocytes. A reduction of leucocyte count and any changes in their activity may lead to disturbances in the immunological system and growth of neoplasm. This paper presents a review of research into the effects of magnetic radiation on leucocytes. It describes, among other things, the influence of MF on leukocyte count changes, leucocyte cellular cycles, chromosome defects and DNA synthesis disorders in leucocytes. There is a lot of discrepancy in literature and at this stage it is difficult to draw consistent conclusion as regards the health effects of MF. Some papers claim that MF may reduce the number of leukocytes and modify their proliferation processes. In addition, there is some risk (although small) that MF will cause the aberration of the leukocyte chromosomes. As a result of leukocytes exposure to MF micronuclei were found in them, as well as changes in the activity of cytokines and natural killer cells. Considering that papers published so far present largely varied results, it is difficult to formulate solid conclusions about MF negative effects.
