Physiotherapists' Understanding of Shortwave Diathermy Contraindications: A Questionnaire Survey.

Purpose: It is known that electromagnetic fields and heat generated by shortwave diathermy (SWD) can have adverse effects on living tissue. The purpose of this research is to evaluate Jordanian physiotherapists' knowledge of pulsed and continuous SWD contraindications. And investigate the potential contraindications about which Jordanian physiotherapists may have limited knowledge. Subjects and Methods: This cross-sectional study investigates Jordanian physiotherapists' knowledge of SWD contraindications. In 38 private and public hospitals, a self-administered questionnaire survey was carried out. Participants were asked to classify 32 conditions as "always, sometime, or never" contraindicated or "I do not know". Participants are physiotherapists with two or more years of postgraduate experience. Two forms comprised the survey. The first consisted of assessing their reaction to the contraindications of pulsed shortwave diathermy (PSWD), while the second consisted of continuous shortwave diathermy (CSWD). Results: Approximately 270 physiotherapists were eligible to participate in this investigation. Only 150 questionnaires were distributed to the therapists who agreed to the study. One hundred twenty-eight were returned for an average response rate of 85.3% (128/150). Respondents had good agreement about using SWD for cardiovascular condition, however, 24 respondents (19%) thought PSWD can be used over venous thrombosis. Only 64% of the respondents was aware that pacemakers are contraindicated for PSWD. Approximately 14% to 32% seem unaware that tuberculosis and osteomyelitis are contraindicated for both CSWD and PSWD. About 21% to 28% have been unaware that the use of PSWD is contraindicated for specialized tissues (eg, eyes, gonads, or malignant tissues) and 29% during pregnancy. Conclusion: Jordanian physiotherapists generally agreed on the widely acknowledged contraindications of CSWD for specific conditions. However, there was considerable uncertainty among Jordanian physical therapists about the contraindications of PSWD. This discrepancy highlights the need to improve physiotherapist awareness and for more fact-based research to the contraindication of SWD modality.

Management of Diabetic Foot Ulcers Using Topical Oxygen Therapy: A Case Series.

BACKGROUND AND AIM: Surgical and endovascular revascularization procedures along with hyperbaric oxygen therapy (HBOT) and topical oxygen therapy (TOT) for chronic oxygen-deprived wounds are standard care treatment protocols for diabetic foot ulcer (DFU). Topical developments in the delivery of topical oxygen therapy have made this a more feasible treatment in practice. The present case series highlights the efficacy of NATROX therapy as TOT in wound healing and the impact of increased oxygenation on ulcer healing in patients with diabetic foot ulcers. METHODS: The TOT was evaluated in 6 patients with DFU who have applied NATROX topical oxygen delivery system for a period ranging from 6 weeks to 24 weeks at Kahel Specialized Centre, located in Olaya, Riyadh, Saudi Arabia. RESULTS: The administration of TOT demonstrated complete wound healing in all the six patients who either had ulcers with minor amputation of toes/heel or had ulcers with other comorbidities in a range from 3 to 8 weeks. CONCLUSION: NATROX therapy is an advanced topical oxygen delivery system compared to other conventional oxygen delivery systems; however, the study warrants further research to assess its potential applicability in DFU wound healing in large sample size and across the races.

The effects of long chain polyunsaturated fatty acids on local activation properties in dogs vulnerable to atrial fibrillation.

Marine derived long chain polyunsaturated fatty acids (PUFAs) were found to have benefits in reducing inducibility and maintenance of atrial fibrillation (AF) in a dog model. This study was conducted to evaluate the effect of PUFAs on local atrial electrical conduction properties acquired via a multi-electrode plaque sutured to the posterior wall of the left atrium of the heart in these dogs. Eleven dogs underwent simultaneous atrioventricular pacing (SAVP) for 2 weeks, and were organized into 2 groups: 5 dogs received no PUFAs (SAVP-PLACEBO), 6 dogs received Eicosapentaenoic or Docosahexaenoic acid derived from fish oils (SAVP-PUFA), where PUFAs were given for 21 days, starting 1 week prior to pacing and during the 2 week pacing period. Three features were extracted, which were the average conduction velocity, average intra atrial conduction time, and total activation time. The PUFA group had a faster average conduction velocity (0.82±0.19 m/s) than the PLACEBO group (0.47±0.21 m/s, P=0.02). Using the average conduction velocity feature, classification was performed with a linear classifier and leave-one-out method. In the SAVP-PLACEBO group, 60% of the dogs were correctly classified, and 66% of the dogs were correctly classified in SAVP-PUFA group, leading to an overall classification accuracy of 63.5%.

Primary retroperitoneal synovial sarcoma in CT and MRI.

Synovial sarcomas are most commonly localized in the extermities, especially the lower thigh and knee areas. Retroperitoneal synovial sarcoma is very rare. We decribe the radiological findings of an adult retroperitoneal synovial sarcoma.
