- The combination of microwave-induced (2450 MHz) hyperthermia and ionizing radiation was used in 7 patients with superficial malignant tumours, which were considered refractory to other therapy. A newly developed heating system was used, allowing for a maintained temperature at the master probe of 42.5 degrees C +/- 0.5 degrees C during 45 min, but temperature measurements at multiple sites showed a marked variation. This preliminary series indicates that the combination of hyperthermia and ionizing radiation may be useful, the response rate (complete or partial) being 8 of 8 evaluable lesions. Even previously heavily irradiated sites responded. Technical improvements are highly needed to allow for controlled heating of any tissue volume.

Technique for microwave-induced hyperthermia in superficial human tumours
- 1982

Ingår i: Acta Radiologica: Oncology. - : Informa UK Limited. - 0349-652X. ; 21:4, s. 235-239
-
Tidskriftsartikel (refereegranskat)abstract
- In order to induce local hyperthermia in superficial tumours a computer system using a 2,450 MHz microwave generator connected to a circular (diameter 90 mm) direct contact applicator was constructed based on invasive temperature control. Small thermistor probes with a diameter of 0.6 mm are inserted in the tumour and surrounding tissues. Eight thermistors can be used simultaneously and one of them is chosen as the "master'. The automatic control system used a pulsed irradiation technique to avoid the problem with interactions between the metallic wires of the temperature probe and the electromagnetic field. With the system it was possible to control the temperature at the master thermistor within +/- 0.5 degrees C from the preset value.

Effect of different radiation fractionation schedules on metastases from an oesophageal carcinoma
- 1980

Tidskriftsartikel (refereegranskat)abstract
- Subcutaneous metastases from an oesophageal carcinoma were irradiated using different schedules. The results have to be evaluated with greatest caution but indicate that with the same CRE value, few fractions caused less skin reactions than several, and the size of the shoulder of the cell survival curve was of the order of 0.7 Gy.

Joint space in normal gleno-humeral radiographs
- 1983
-
Ingår i: Acta Orthopaedica Scandinavica. - : Medical Journals Sweden AB. - 0001-6470. ; 54:2, s. 274-276
-
Tidskriftsartikel (refereegranskat)abstract
- The gleno-humeral joint space in standard antero-posterior images of 175 normal subjects was measured at three different sites. The average of the three measurements, the integral joint space, was calculated and was found to be between 4 and 5 mm. The value does not change with age, except in women, in whom it increases slightly. A narrow joint space in an elderly patient should not be expected simply because the patient is old. The measuring technique described is useful in population studies. In individual cases a simple measurement with a ruler serves the same purpose.

The subacromial space in normal shoulder radiographs
- 1984
-
Ingår i: Acta Orthopaedica Scandinavica. - : Medical Journals Sweden AB. - 0001-6470. ; 55:1, s. 57-58
-
Tidskriftsartikel (refereegranskat)abstract
- The subacromial space in standard anteroposterior radiographs of 175 normal shoulders was between 9 and 10 mm. The space was significantly greater in men, with a slight reduction with age. In middle age, a subacromial space less than 6 mm is pathological, possibly indicating supraspinatus tendon rupture.

A Study of Indoor Aerosol Size Distribution and Attachment of Radon Daughters
- 1983

Ingår i: Journal of Aerosol Science. - : Elsevier BV. - 0021-8502. ; 14:3, s. 455-458

Konferensbidrag (refereegranskat)abstract
- The particle size distribution in 11 different dwellings was studied during 5-7 days, samples being taken every 15 min. Large variation in the aerosol concentration has been found. Also the size distribution of the aerosol varies depending on the level of activity in the home, e.g. smoking and cooking. The average area median diameter found in the dwellings was 0.2 ,am. A technique for the measurement of radon daughter distribution on different airborne matter was developed and tested. The method is based on the use of an electrical mobility analyzer and alpha-spectrometry of the radon daughters collected on a fluoropore filter. Some results are presented and discussed.
