Disturbances in the function of cardiac pacemaker caused by short wave and microwave diathermies and pulsed high frequency current.

The effect of short wave diathermy, pulsed high frequency current (Diapulse, Curapuls) and microwave diathermy on the function of an implantable cardiac pacemaker and its leads was examined by measuring the output (voltage) and rate of the pacemaker under various experimental conditions. It appeared that all these devices had a decreasing effect on the output and an increasing effect on the rate of the pacemaker. When therapeutic doses (power) were applied the greatest changes in output and rate were caused by microwave diathermy and the slightest by Curapuls. The clinical precautionary measures based on these observations are discussed.

Pulsating shortwave diathermy: value in treatment of recent ankle and foot sprains.

The effects of 2 pulsating shortwave diathermy treatments (Diapulse and Curapuls) were compared with placebo treatment in recent ligamentous injuries of ankle and foot in 300 outpatients. The areas of comparison were reduction in swelling, recovery of strength and range of motion of the injured ankle, improvement of walking ability, and duration of disability. There were only slight differences between Diapulse and Curapuls treatment groups. No statistically significant differences could be observed in the recovery of strength and range of motion or in the duration of disability among the 3 groups, although walking ability in the Diapulse group recovered better than in the placebos (p less than 0.01) and reduction of swelling was significantly better for Curapuls (p less than 0.001 than for placebos.

Is diathermy safe in women with copper-bearing IUDs?

Ultrasound and short-wave diathermy are widely used in physiotherapy to induce heating of deep tissues, since this causes a concomitant increase in local blood flow. A metallic implant in the treated field is generally regarded as a contra-indication to diathermy because of the risk of thermodamage to surrounding tissues. It is not certain, however, if copperbearing IUDs contain sufficient metal as to constitute a risk. In order to exclude the possibility that diathermy might lead to intra-uterine burns in women using copperbearing IUDs a technique was devised of measuring temperatures in the copper wire of an IUD in situ during short-wave an ultrasonic therapy. The results indicate diathermy to be perfectly safe in women whit copper-bearing IUDs.

The effectiveness of manual therapy, physiotherapy, and treatment by the general practitioner for nonspecific back and neck complaints. A randomized clinical trial.

In a randomized trial, the effectiveness of manual therapy, physiotherapy, continued treatment by the general practitioner, and placebo therapy (detuned ultrasound and detuned short-wave diathermy) were compared for patients (n = 256) with nonspecific back and neck complaints lasting for at least 6 weeks. The principle outcome measures were severity of the main complaint, global perceived effect, pain, and functional status. These are presented for 3, 6, and 12 weeks follow-up. Both physiotherapy and manual therapy decreased the severity of complaints more and had a higher global perceived effect compared to continued treatment by the general practitioner. Differences in effectiveness between physiotherapy and manual therapy could not be shown. A substantial part of the effect of manual therapy and physiotherapy appeared to be due to nonspecific (placebo) effects.

The effect of local heat and cold therapy on the intraarticular and skin surface temperature of the knee.

OBJECTIVE: To evaluate the effects of local application of ice chips, ligno-paraffin, short-wave diathermy, and nitrogen-cold air on skin and intraarticular temperature. METHODS: Forty-two healthy subjects were divided into 4 treatment groups. A temperature probe was inserted into the knee joint cavity and another placed on the overlying skin, and changes in temperature over 3 hours, by treatment group, were recorded. RESULTS: The mean skin surface temperature dropped from 27.9 degrees C to 11.5 degrees C after application of ice chips, and from 28.8 degrees C to 13.8 degrees C after application of cold air. The mean intraarticular temperature decreased from 31.9 degrees C to 22.5 degrees C and from 32.9 degrees C to 28.8 degrees C, respectively, after these 2 treatments. Shortwave diathermy increased skin temperature by 2.4 degrees C; intraarticular temperature was increased only 1.4 degrees C by short-wave diathermy. Treatment with ligno-paraffin increased the skin surface temperature 8.9 degrees C; the temperature in the joint cavity was increased 3.5 degrees C. CONCLUSION: The use of short-wave diathermy and superficial heat packs in the treatment of patients with arthritis may potentially cause harm by increasing intraarticular temperature. This may have major implications regarding treatment policy for patients with arthritis.

Magnitude and duration of UV-B-induced tolerance.

Using repeated minimal erythema dose (MED) testing, we investigated the magnitude and duration of tolerance to short-wave UV radiation in the B range (UV-B) in 37 patients with psoriasis who received at least 12 UV-B phototherapy treatments. Without substantial erythema developing, half of the patients received UV-B doses in excess of 13 times their pretreatment MED dose and a fourth received UV-B doses in excess of 28 times their pretreatment MED dose. On average, tolerance faded to about half that present at the last UV-B treatment in 3 weeks. Six weeks after therapy was stopped, most posttreatment MEDs were less than twice the pretreatment MED. The magnitude of tolerance achieved and the rate of decay did not vary with skin type. Our findings indicate that repeated exposures to suberythemal or mildly erythematous doses of UV-B can induce exceptional degrees of tolerance to UV-B radiation. The duration of this increase in tolerance is, however, short.

[Analysis of substances issuing from Zajdela ascitic hepatoma cells after exposure to UV radiation of different wave-lengths. I. Relationship to dose].

The release of substances from the Zaidela ascitic hepatoma cells after irradiation with physiological doses of short-wave (254 nm) and long-wave (300-380 nm) UV light (far and near UV light) has been studied spectrophotometrically. Within the range of 200-520 nm, the absorption spectra of releasing substances show maxima at 215 and 260 nm and are identical to spectra of non-irradiated cells. The amount of substances increases with dose making up, at the maximal alteration, 180-220%, of the amount releasing from non-irradiated cells. Irradiation with far UV light exceeds by one order that with near UV light. The effect of minimum doses is opposite to the action of high doses: the release of substances from irradiated cells is much less.
