Potentials for change.

Taking as a point of departure the perspective of a behavioural scientist the need to move from a clinical to a sociological perspective is stressed. The difference between microsociologically and macrosociologically induced changes is emphasized. The former depending on interpersonal relations and to some extent open to our conscious efforts to achieve change. The latter depending on major social transformations which we usually cannot manipulate according to our wishes. We are here faced with a dilemma since our wishes for changes in sexual behaviour usually are of a magnitude that would require macrosociologically induced changes (which we cannot control) whereas our ability to interfere in the process is limited to microsociologically induced changes (which will not produce the results we hoped for). In view of this it is argued that it is necessary to act within the bounds of our respective cultures and to establish not only general objectives but also culture specific targets. These may, however, often appear to be in conflict with more general values in a given society. This reflects a perennial dilemma in occidental culture where sexual behaviour on the one hand is to be love based (and thus at least partly irrational) and on the other hand to be responsible (i.e. extremely rational).

Endodontic status and suggested treatment in a population requiring substantial dental care.

The purpose of this study was to analyse endodontic status and treatment suggested for Swedish citizens requiring substantial dental care. According to the Swedish dental insurance system, treatment plans including radiographs have to be submitted for approval if the estimated cost of treatment exceeds a certain level (USD 500 in 1977). A sample of 1094 treatment plans received during 1977 and 1978 was randomly selected. In the radiographs the number of remaining teeth was recorded, periapical condition was evaluated and the quantity and quality of previous endodontic treatment were estimated. In addition, treatment plans concerning the teeth with periapical lesions were studied. The results indicated that patients analysed in this study that needed expensive treatment had more missing teeth, more root-filled teeth and more teeth with periapical lesions than what has been reported in previous studies of samples supposed to accurately represent the Swedish population. However, the technical quality of the root fillings and the frequency of periapical lesions in root-filled teeth were the same as in previous studies, with high frequencies of inadequate root fillings and related unfavourable responses. Thus the patients in this study retained a significant need for endodontic treatment despite having already received a great deal of endodontic care. Further, it was found that nearly half of the observed periapical lesions would not be treated based on the submitted plans.

Lower extremity swelling: computerized tomography following negative venography.

In 21 patients who had lower extremity swelling and negative venography, radiographic evaluation was extended to include computerized tomography (CT) of the lower extremity, which we have termed venography-CT, or VCT. All patients were referred with the diagnosis of deep vein thrombosis (DVT) and no patient had a history of trauma. CT was effective in demonstrating two occult mechanisms of lower extremity swelling: knee joint effusion (three patients) and intramuscular hemorrhage (five patients). Selective utilization of CT in the evaluation of lower extremity swelling is effective in directing the clinical management of these patients.

Complications of percutaneous nephrolithotomy.

Of 582 patients who underwent percutaneous nephrolithotomy, 4% had complications. The most common complications were fever (23%) and bleeding necessitating transfusion (12%). Extravasation was seen in 7% of patients and transient ureteral obstruction in 6%. Other complications included pneumothorax or hydrothorax, pneumonia/atelectasis, paralytic ileus, nephrostomy-tube dislodgment or urine drainage from the flank lasting more than 1 week, significant infection, urinoma formation, renal pelvic laceration, ureteral avulsion, ureteropelvic or ureteral stricture, bowel injury, or escape of stone fragments into the retroperitoneum. Seven patients (1%) required immediate surgery: four to repair renal pelvic lacerations, one to repair a ureteral avulsion, and two to control bleeding after nephrostomy-tube removal when embolization failed. Four patients required delayed surgery for ureteral or ureteropelvic junction strictures, which may have been caused by a tissue reaction to the stones rather than by the procedure itself. There were two deaths--one from respiratory failure in a patient with severe interstitial pulmonary fibrosis and chronic renal failure and the other from myocardial infarction in an obese diabetic patient with hypertension.

Attitudes among adolescents in a Swedish city toward some sexual crimes.

Using data from a representative sample of adolescents in grade ten in Uppsala, the fourth largest city in Sweden, attitudes toward a number of (criminal) sexual acts are studied. These data are contrasted with those from a sample of patients at a school gynecological clinic. It is found that for both samples, only a very limited number of the eight discussed acts are considered to be criminal by the adolescents. Although at least seven or eight acts are criminal in Swedish law, only two acts are considered criminal by about half of the respondents. These acts are pedophilia and rape after petting. The same questions were used by Kutchinsky in 1969 when on behalf of the U.S. Congress Commission on Obscenity and Pornography he studied inhabitants in Copenhagen, Denmark. When comparing data from Uppsala Sweden 1978 with data from Copenhagen, Denmark 1969 we find that Swedish adolescents in the late seventies, on the whole are much less likely to call the discussed acts criminal. The only exception is rape after petting, which in Copenhagen in the late sixties was the act least often seen as criminal but in the Uppsala study in the late seventies it was one of the two acts most often claimed to be criminal. Finally, the effects of coital experience and the effect of sexual knowledge on the percieved criminality of the acts are considered.

The adolescent boy and girl: first and other early experiences with intercourse from a representative sample of Swedish school adolescents.

Attitudes and sexual experiences among adolescents have been studied using data from a representative sample of pupils in tenth grade in Uppsala, the fourth largest city in Sweden. Sex differences in coital experience, coital frequency, and evaluation of coital frequency are analyzed. The importance of traditional sex roles is discussed, and the differential sexual socialization of boys and girls is commented on. The data help convey a picture of an adolescent boy who feels deprived of heterosexual outlets and whose sexual relations with girls are sudden, unplanned, and characterized by limited emotional involvement; the adolescent boy is also quite discontent. This picture is contrasted with that of the girls, about whom it is found that, compared with the boys, a greater proportion have coital experience, the average age at first intercourse is lower, and the average number of experiences with intercourse during the last month is higher; to a greater extent than the boys, the girls are satisfied with how often they have intercourse.
