Relation between lung function, exercise capacity, and exposure to asbestos cement
- 1987
-
Ingår i: British Journal of Industrial Medicine. - 0007-1072. ; 44:8, s. 542-549
-
Tidskriftsartikel (refereegranskat)abstract
- A group of 137 male workers with known exposure (mean 20 fibre years per millilitre) to asbestos cement who had symptoms or signs of pulmonary disease was studied together with a reference group of 49 healthy industrial workers with no exposure to asbestos. Lung function measurements were made at rest and during exercise. Evidence of lung fibrosis was found as well as of obstructive airways disease in the exposed group compared with the reference group. Asbestos cement exposure was related to variables reflecting lung fibrosis but not to variables reflecting airflow obstruction. Smoking was related to variables reflecting obstructive lung disease. Exercise capacity was reduced in the exposed workers and was related to smoking and to lung function variables, reflecting obstructive airways disease. There was no significant correlation between exercise capacity and exposure to asbestos cement.

Ankle fractures
- 1987
-
Ingår i: Foot and Ankle. - 0198-0211. ; 8:1, s. 23-25
-
Tidskriftsartikel (refereegranskat)abstract
- The results of three separate studies on ankle fractures are presented. Clinical information is provided concerning the epidemiology and a comparison of closed versus open treatment, and a discussion is presented concerning what results can be expected 30 years after closed treatment for an ankle fracture.

Supination-eversion fractures of the ankle joint: changes in incidence over 30 years
- 1987
-
Ingår i: Foot and Ankle. - 0198-0211. ; 8:1, s. 26-28
-
Tidskriftsartikel (refereegranskat)abstract
- The sex- and age-specific incidence has been calculated for ankle fractures from the first part of the 1950s and compared with the 1980s, a 30-year interval. The fractures were also classified according to Lauge-Hansen. Altogether 1784 fractures were found. During that time interval ankle fractures had become more common, particularly those with extensive skeletal involvement, such as the stage IV supination-eversion fractures, which today have an incidence pattern more typical of a fragility fracture in elderly women.

Early post-traumatic changes in hemodynamics and pulmonary ventilation in alcohol-pretreated pigs
- 1987
-
Ingår i: Journal of Trauma. - 0022-5282. ; 27:1, s. 40-44
-
Tidskriftsartikel (refereegranskat)abstract
- Time relations among trauma, pulmonary and systemic circulation, and lung function were studied in pigs. Eleven animals (b.w. 25-30 kg) were investigated under balanced anesthesia. Ventilation was mechanically controlled. Hemodynamics, pulmonary ventilation, and gas exchange were serially recorded. Seven animals were pretreated with 40% ethanol in saline and four with saline only. Ninety minutes after the ingestion of alcohol or saline, the animals were subjected to a standardized soft-tissue trauma. Cardiac output decreased significantly 2 minutes after trauma and remained low in both groups throughout the observation period of 30 minutes. Pulmonary vascular resistance was significantly increased in the alcohol-pretreated group but was virtually unchanged in the control animals. Systemic vascular resistance was similarly reduced in the two groups. Total compliance was somewhat lower in alcohol-pretreated animals and 10 minutes after the trauma arterial oxygen tension was significantly lower in the alcohol group than in control animals. Carbon dioxide elimination was reduced after trauma in both groups. It is concluded that pulmonary vascular response increased and that total pulmonary compliance is somewhat decreased shortly after trauma in the alcohol group while gas exchange is almost unchanged. The results indicate a negative interaction between alcohol and trauma

Microwave-induced hyperthermia and radiotherapy in human superficial tumours: clinical results with a comparative study of combined treatment versus radiotherapy alone
- 1987
-
Ingår i: International Journal of Hyperthermia. - : Informa UK Limited. - 0265-6736 .- 1464-5157. ; 3:5, s. 393-411
-
Tidskriftsartikel (refereegranskat)abstract
- Eighty-five evaluable superficial recurrent malignant tumours, mainly adenocarcinomas (78 per cent), in 38 patients were treated with either combined local hyperthermia (41-45 degrees C for four sessions) and low dose radiotherapy (30.0 Gy) or the same low dose radiotherapy alone. The treatment was given for two weeks. Hyperthermia was induced externally with 2450 MHz or 915 MHz microwaves. Totally 57 tumours were given combined treatment with a complete and partial response rate of 46 and 30 per cent, respectively (duration 1-38 months). In 18 patients with 2-10 superficial tumours each, 56 tumours were used in a comparative study, comparing the effect of combined hyperthermia and low dose radiotherapy versus the same low dose radiotherapy alone, the patients acting as their own controls. The total response rates were 89 and 50 per cent, respectively, in the two treatment modality groups. The difference in response rates is significant (p = 0.0039) in favour of the combined treatment, and this is also found when comparing complete remissions only (p = 0.0027). Local pain and normal tissue reactions presented problems during and after 2450 MHz microwave-induced hyperthermia treatment, performed without a coupling water bag system. Introduction of 915 MHz microwave-induced hyperthermia with a coupling deionized water bag system and refinement of microwave applicators, as well as the temperature control system considerably reduced these problems.

Psychological reactions to cancer risks after the Chernobyl accident
- 1987
-
Ingår i: Medical Oncology. - : Humana Press. - 1559-131X .- 1357-0560. ; 4:3-4, s. 259-271
-
Tidskriftsartikel (refereegranskat)abstract
- This is a report on an investigation of people's reactions to the Chernobyl accident. Interviews and, mail surveys were conducted in July-September 1986 with pregnant women, parents of newborn children, farmers, adolescents and men who were not parents, in various areas of Sweden, differing as to the amount of Chernobyl fallout they had received. The accident had probably doubled the number of people who were negative to nuclear power in the most affected area. Radiation risks were highly salient in most groups. Areas differed in the expected direction, people in the more, exposed areas being more concerned. Women were more worried and more negative to nuclear power than men while adolescents appeared to be the group least affected by the accident. Farmers were also strongly opposed to nuclear power and concerned about its risks. Nuclear attitude could be well accounted for by attitude statements and rated basic life values. It was quite stable over a 1 month period.

Pharyngeal function in patients with rheumatoid arthritis of the cervical spine and temporomandibular joint
- 1987
-
Ingår i: Acta Radiologica. - 1600-0455. ; 28:1, s. 35-39
-
Tidskriftsartikel (refereegranskat)abstract
- Pharyngeal function was studied in 31 patients with rheumatoid arthritis. Eighteen of these patients had dysphagia. Cervical spine abnormalities were present in 14. Destruction of the capitulum and/or ramus of the mandible was registered in 9. Pharyngeal dysfunction was revealed in 20. Patients with a vertical dislocation of the C1-C2 in relation to the occipital bone and patients with destruction of the capitulum and/or ramus of the mandible had an increased frequency of pharyngeal dysfunction. Pharyngeal dysfunction is thought to be due to mechanical factors and caused by derangements of muscular attachments and turning points.

Radiographic findings after cricopharyngeal myotomy
- 1987
-
Ingår i: Acta Radiologica. - 1600-0455. ; 28:5, s. 555-558
-
Tidskriftsartikel (refereegranskat)abstract
- Single film examinations (iodine and/or barium) were reviewed in 28 patients who had undergone surgery on the cricopharyngeal muscle due to Zenker diverticula (24 patients), cricopharyngeal muscle incoordination (3 patients) and pharyngoesophageal web (one patient). All patients had had a myotomy which included the cricopharyngeal muscle and up to 3 cm of the cervical esophagus. Lateral and anterior deviation of the pharynx and cervical esophagus occurred regularly. A pharyngocutaneous fistula developed in 2 patients which healed within 3 weeks. In 5 patients there was a posterior leak of contrast medium during the first postoperative week which healed within 2 weeks. Six of these seven patients with a fistula or a leak had had either a diverticulum removed or sustained an accidental mucosal perforation. No patient had recurrence of diverticula, although, 9 patients developed a cricopharyngeal muscle impression. Iodine and barium examinations are important for monitoring early and late postoperative changes after cricopharyngeus myotomy.
