[Application of radiofrequency hyperthermia for treating advanced urinary bladder cancer--a case report].

A patient with advanced urinary bladder cancer treated with a combination of radiation and hyperthermia, using short-wave radiofrequency (RF) and intravesical irrigation with warm water is reported. The tumor temperature was successfully maintained at 43 degrees to 44.6 degrees by external application of 13.56 MHZ RF when the bladder was irrigated with heated saline (intravesical temperature: 43 degrees) Hyperthermia was performed for 30 min immediately after each course of external bladder irradiation (Linac: 400 rad, twice a week; total 5 weeks exposure of 4000 rad). The tumor disappeared completely (CR) after the completion of the combination therapy.

UV-B-induced bullous pemphigoid restricted to mycosis fungoides plaques.

We describe a 77-year-old female patient with plaque-stage mycosis fungoides (MF) who developed bullous lesions in lesional skin only, while receiving short-wave ultraviolet radiation (UV-B) therapy. Histopathological and immunohistochemical examination resulted in a diagnosis of bullous pemphigoid (BP). Withdrawal of the UV-B treatment and application of a high-potency topical corticosteroid cream resulted in a rapid regression of the BP. As the bullous lesions were strictly confined to the MF plaques, the cutaneous infiltrate was probably involved also in the development of the BP. To our knowledge, this is the second case report of the coexistence of MF and BP and the first one in which the BP might be UV-B-induced.

Controlled comparison of short-wave diathermy treatment with osteopathic treatment in non-specific low back pain.

The effectiveness of spinal manipulation carried out by a non-medical qualified osteopath was compared with that of short-wave diathermy (SWD) and a placebo (detuned SWD) in 109 patients with low back pain. More than half the subjects in each of the 3 treatment groups benefited immediately from therapy. Significant improvements were observed in the 3 groups at the end of 2 weeks' treatment, and these were still apparent at 12 weeks. The outcome of treatment was unrelated to the initial severity or duration of pain or to the trend of pain towards deterioration or improvement. It is, therefore, unlikely that the results simply reflect the natural history of low back pain. Benefits obtained with osteopathy and SWD in this study may have been achieved through a placebo effect.

[Modification of cardiac pacemakers of the MCP and LCP series by electrodiagnostic and electrotherapy procedures].

47 patients with cardiac pacemakers of the MCP- and LCP-series were examined for influence by disturbances caused by devices of electrodiagnostics and electrotherapy used in the GDR. A general prohibition of such diagnostic and therapeutic methods cannot be maintained. Low frequency current therapy (apart from TENS-currents), hydrogalvanic baths and ultrasonic therapy could be applied without any danger. In the CP-current should be guaranteed a minimum distance of 50 cm, when it fell short of, however, only insignificant disturbances appeared. The same concerns the microwave therapy. Also electrodiagnostics was possible without endangering the pacemaker-patient. TENS-currents caused, depending on distance and frequency, no disturbances or dangerous ones (total inhibition). Short-wave repeatedly led to total inhibition or warming at the cardiac pacemaker and should therefore generally be forbidden.

Short-wave ultraviolet light (UVB) treatment of allergic contact dermatitis of the hands.

7 out of 10 patients with long-standing allergic contact dermatitis of their hands were successfully treated with short-wave ultraviolet light (UVB) and the contact dermatitis healed completely. To maintain this result they had to receive UVB therapy regularly once a week. The last 3 patients also showed improvement, but they had periods with vesiculation during the treatment. UVB treatment seems to be a valuable supplement for the treatment of contact dermatitis.

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.

[Single preoperative radiation and short-wave treatment of breast cancer].

A total of 93 patients were assigned to receive either radiation treatment alone (group 1) or in combination with local microwave-induced hyperthermia (group 2) prior to mastectomy. The treatment results were compared. Within a two-year follow-up period, all patients of group 2 remained free of relapse, metastases being registered in 2 (6.2%) cases. In group 1, relapse was observed in 1 case, whereas metastasis--in 7 (11.5%). The study failed to establish drug-induced tumor pathomorphosis in 12.5% in group 2 and 73.8% in group 1. The procedure did not interfere with surgery, nor was it followed by an increased postoperative complication rate.

Exacerbation of a case of myasthenia gravis during therapeutic electric stimulation.

In patients with myasthenia gravis, vigorous exercise and electric stimulation produce weakness that is usually reversed by rest. We describe a case of persistent weakness in a 31-year-old woman with myasthenia gravis following therapeutic electric stimulation. She was injured in an automobile accident, with cervical and lumbar muscle strain diagnosed by a local emergency room physician. She consulted a chiropractor two days later because her symptoms had not abated. The chiropractic treatment of short-wave diathermy, high-voltage electric stimulation and spinal manipulation continued thrice weekly for six weeks. She then presented to her neurologist, complaining of persistent fatigue, weakness, increased diplopia, cervical and occipital pain, and disrupted sleep. Neck weakness had developed since her last visit. She was admitted to the hospital for evaluation. Neurologic exam showed no other abnormality of strength, sensation, or reflexes. The exacerbation of myasthenia responded to prednisone and increased pyridostigmine. After two months she required only her preinjury dose of pyridostigmine (60 mg q.d. p.r.n.) to prevent diplopia or fatigue, and her strength was normal. Repeated electrically induced muscle contraction is suspected of causing this exacerbation of myasthenia gravis.

Reduction of radiofrequency exposure to the operator during short-wave diathermy treatments.

Radiofrequency electromagnetic fields near short-wave diathermy equipment operating at a frequency of 27.12 MHz can expose the physical therapist to levels above those recommended in standards for radiofrequency exposure in Western countries. Electric and magnetic fields around air-gap, diplode, monode and circuplode applicators were mapped by the author. Large differences in stray field intensities were found for the various applicators. The air-gap electrodes caused the highest levels of unwanted radiation, and the circuplode caused the lowest levels. The use of the circuplode would normally ensure an operator exposure far below the levels in recommended standards. In order to reduce the exposure during the first few minutes of a treatment, when air-gap electrodes or diplode are used, the operator should stand at the end of the diathermy console opposite to the applicator and cables and not, as is often the case, at one side. It is recommended that manufacturers change the design of the diathermy console (a minor modification) in order to ensure this operating position.

[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.

[Analysis of substances issuing from Zajdela ascitic hepatoma cells following exposure to UV radiation of different wavelength. II. Proton release].

The release of protein from the Zaidela ascitic hepatoma cells following irradiation with physiological doses of short-wave (254 nm) and long-wave (300--380 nm) UV light (far and near UV radiation) has been investigated. The amount of protein increases with dose making, upon the maximal radiation damage, 180 and 2 per cent of the protein against, resp., the protein amount releasing from non-treated cells and the total protein of the intact cell. The far UV light is by one order more efficient than the near UV light. Irradiation of cells with the former and the latter results in the release of high and low molecular proteins, resp. The near UV irradiation brings about heavier releasing of proteins than does the far UV light.
