Injuries due to deliberate violence in areas of Denmark. I. The extent of violence.

As part of a transcultural investigation of violent behavior in Denmark and South America an analysis was made during a one year period of the incidents involving deliberate violence as registered at 3 Danish emergency wards, and at the Institute of Forensic Medicine in Copenhagen. In the three emergency wards a total of 1316 victims of deliberate violence were observed corresponding to a rate of about 3.3/1000 per year in a provincial/rural district, the catchment region of Holbaek County Hospital, 5.5/1000 per year in a mainly middle income area of the metropolis Copenhagen, the catchment region of Frederiksberg Hospital, and 7.6/1000 per year in a mainly low income area of Copenhagen, the catchment region of the Rigshospital. The highest risk, 28/1000 per year, was found for young men between 15 and 19 years of age living in the low income area of Copenhagen. The risk was low for people greater than or equal to 60 years of age in all three areas investigated, ranging from 0 (men) to 1.3/1000 per year (women). Skilled and unskilled workers were greatly over represented as victims of violence, considering their share of the background population. Seventy percent of the victims were men. At least 44% of the men and 32% of the women were alcohol intoxicated when arriving in the emergency ward. The incidents took place in restaurants or in the vicinity of restaurants for 30% of the male and 11% of female victims respectively, while 45% of the women had been subject to deliberate violence at home. The rate of fatal cases of deliberate violence in the Eastern part of Denmark, the catchment area for the Institute of Forensic Medicine in Copenhagen, was found to be 0.02/1000 per year. The risk of becoming a victim of deliberate violence has not increased during the last 4 years comparing with similar investigations from other parts of Denmark. However, the rate of homicide seems to have increased, and so has the severity of the injuries caused by deliberate violence. The pattern of deliberate violence appears to be associated with socio-economic and cultural factors, and to be closely linked with alcohol intoxication.

Injuries due to deliberate violence in areas of Denmark. II. Victims of homicide in the Copenhagen area.

As part of a transcultural investigation of injuries due to deliberate violence in Denmark and South America, homicides in the Copenhagen area were studied for a 1-year period. Forty-five cases corresponding to a rate of approximately 2/10(5) per year were recorded. The rate seems to be increasing and the pattern changing with a higher frequency of stabbing and with an increasing frequency of high blood-alcohol concentrations in the victims. The highest number were killed at home. In the majority of cases the aggressor and the victim knew each other. A reduction in alcohol consumption is indicated as a possible preventive measure.

Injuries due to deliberate violence in areas of Denmark. IV. Alcohol intoxication in victims of violence. The Copenhagen Study Group.

A material of 1316 victims of deliberate violence was collected prospectively during a one year period in three Danish emergency wards covering a provincial/rural area and two metropolitan areas. The frequency of alcohol intoxication was determined. Forty-one percent of the patients were intoxicated. The highest frequency was found in male victims, in the provincial/rural area, in restaurants or their vicinity, in the age group 35-49, during evenings and nights and in May. It is difficult to indicate specific preventive measures. However, a more restrictive attitude is suggested with regard to serving alcohol to intoxicated persons in restaurants.

Injuries due to deliberate violence in areas of Denmark. III. Lesions. The Copenhagen Study Group.

As part of a transcultural investigation of violent behavior in Denmark and South America, the lesions from accidents involving deliberate violence registered in three Danish emergency wards during a 1-year period were studied. A quantity of 2211 lesions were diagnosed in 1316 patients (953 male and 363 female patients). Sixty-five percent of the lesions were in the head/neck region, 13% in truncus, 18% in the upper extremities and 5% in the lower extremities. The most frequent diagnosis was an open wound in the head/neck region. Adding contusions and fractures in the same region this amounted to more than half of the total number of lesions. In the upper extremities 62% of the lesions were contusions or open wounds. Serious lesions of internal arteries were few, however always caused by sharp instruments (knives). Serious lesions due to firearms were not recorded/reported. Strangulation had been used against 1.1% of the victims, the male/female ratio being 1:6. The main part of the lesions were of minor severity when assessed on the basis of the scores in the Abbreviated Injury Scale (AIS). The lesions were, however, more serious compared to other recent studies, and it appeared that the female victims had fewer but more serious lesions than the male victims. The need for treatment and hospitalization was in the range of other recent studies.

Injuries due to deliberate violence in areas of Denmark. V. Violence against women and children. Copenhagen Study Group.

As part of an European-South American study of deliberate violence cases of violence against women greater than or equal to 15 years of age and violence against and among children under the age of 15 years were registered at 3 Danish emergency wards and at the Institute of Forensic Medicine in Copenhagen. 352 cases of violence against women and 46 cases of violence against children were registered in the three emergency wards corresponding to rates of about 1.6/1000 per year for women, 0.6/1000 per year for boys and 0.7/1000 per year for girls in a provincial/rural district, the catchment region of Holbaek County Hospital, 3.4/1000 per year for women, 2.8/1000 per year for boys and 0.6/1000 per year for girls in a mainly middle income area of the metropolis Copenhagen, the catchment region of Frederiksberg Hospital, and 4.0/1000 per year for women, 4.0/1000 per year for boys and 0.9/1000 per year for girls in a mainly low income area of Copenhagen, the catchment region of the Rigshospital. Nineteen live adult female victims and 17 dead adult female victims of violence were registered in the Institute of Forensic Medicine in Copenhagen, where also one was registered as a victim of homicide. Nearly half of the adult live female victims of violence had been injured at home while this was the case for approximately three fourth of the dead victims. In 35% of the live cases the husband was the aggressor and in 12% a former cohabitant. In 71% of the homicide cases the husband was the aggressor. The live women appeared to have fewer but more serious lesions than men. The pattern of deliberate violence against women appears to be associated with socio-economic and cultural factors. In cases with a preceding quarrel there is statistically a link to alcohol intoxication. In half of the cases of violence against children the aggressor was known to the victim, in 15% the aggressor was one of the parents, while 42% of the cases were violence among children. The pattern of violence according to sex, and the distribution and severity of lesions for 10-14 years old children showed resemblance to the situation for adults. The lesions were more serious in young infant victims, especially boys, than in adult victims.

Histologic changes and silicone concentrations in human breast tissue surrounding silicone breast prostheses.

Using a previously developed method for quantitative measurements of silicone concentrations in breast tissue, material from 86 biopsies from 67 breasts in 55 patients who had silicone implants was examined. In the 49 breast with unruptured prostheses, there was a positive relation between the concentrations and inflammatory reactions, the only exception being the amount of plasma cells, which showed a negative relation. It is concluded that silicone prostheses provoke an inflammatory response not only because they act as foreign bodies, but also because of silicone seepage through intact membranes.

Prevalence of silicone breast implant rupture among Danish women.

The durability of silicone gel-filled breast implants is of concern, but there are few epidemiological studies on this issue. To date, most of the relevant findings are derived from studies of explantation, which suffer from bias by including women with symptoms or concerns about their implants. As part of a long-term magnetic resonance imaging study of the incidence of rupture, this study involved 271 women with 533 cosmetic breast implants who were randomly selected from among women who underwent cosmetic breast implantation from 1973 through 1997 at one public and three private plastic-surgery clinics in Denmark. The prevalence of rupture was determined from the first magnetic resonance screening. The images were evaluated by four independent readers, using a standardized, validated form. The outcomes under study were rupture, possible rupture, and intact implant. Ruptures were categorized as intracapsular or extracapsular. Overall, 26 percent of implants in 36 percent of the women examined were found to be ruptured, and an additional 6 percent were possibly ruptured. Of the ruptured implants, 22 percent were extracapsular. In multiple regression analyses, age of implant was significantly associated with rupture among second- and third-generation implants, with a 12-fold increased prevalence odds ratio for rupture of implants that were between 16 and 20 years of age, compared with implants between 3 and 5 years of age. Surgitek implants (Medical Engineering Corporation, Racine, Wis.) had a significantly increased prevalence odds ratio of 2.6 for rupture, compared with the reference implants. No significant association was found with the position (subglandular or submuscular) or the type of implant (single- or double-lumen). Extracapsular ruptures were significantly associated with a history of closed capsulotomy (p = 0.001). In the future, the authors plan to examine the women in their cohort with a second magnetic resonance imaging scan to establish the incidence of rupture, a parameter unknown to date in the literature, and to further characterize those factors associated with the actual risk of rupture.

Silicon in human breast tissue surrounding silicone gel prostheses. A scanning electron microscopy and energy dispersive X-ray investigation of normal, fibrocystic and peri-prosthetic breast tissue.

Implanted silicone breast prostheses leak silicone gel through the intact membrane. In order to determine the exact location and to achieve a semiquantitative estimation of the amount of silicone in the surrounding tissue, a method involving scanning electron microscopy (SEM) and energy dispersive analysis of X-rays (EDAX) was used. By this method we were able to demonstrate the presence of the element silicon (Si) (main component of silicone, a polymer with a general formula e.g. (CH3[Si(CH3)2O]n Si(CH3)3 along the inner border of vacuoles corresponding to the light microscopic localization of droplets and in macrophages. The tissue adjacent to the prostheses had a higher silicon content than the control tissue.

[Silicone breast implants]. / Silikonebrystproteser.

A brief review of the use of silicone breast implants, their structure, methods of implantation and complications is presented. Acute complications are rare, being mainly infection and hematoma. Long-term complications, on the contrary, are common, consisting mainly of capsular contracture around the prosthesis with subsequent pain and deformation of the breast. More rarely silicone granulomas form, and prosthesis rupture or herniation occurs. The importance of silicone leakage for these complications is discussed separately as well as the treatment of and prevention of capsular contracture and demonstration of silicone in tissue. A critical attitude towards the use of silicone breast implants, when these are used for purely cosmetic purposes, is recommended at present. New improved types of silicone breast implants are currently being tested clinically.

Simultaneous dislocations of the bases of the four ulnar metacarpals upon the last row of carpals.

Carpometacarpal dislocation of the base of one or more of the four ulnar metacarpals is extremely rare. This case report describes a carpometacarpal dislocation of all four ulnar metacarpals treated with open reduction under anaesthesia and internal skeletal fixation for six weeks. The result twelve weeks after the accident was functionally and anatomically excellent.

Five years experience of breast augmentation using silicone gel prostheses with emphasis on capsule shrinkage.

The results of a five-year retrospective study on breast augmentation using silicone gel-filled prostheses are presented. A total of 115 breasts (45%) out of 254 developed capsules of type II-IV. The incidence in the hypoplasia group was 46%. The capsules were treated with closed and/or open capsulotomy. Biopsies showed fibrous capsules containing alcianophilic droplets, suggesting the presence of silicone in the tissue. The authors find the above incidences to be unacceptably high, and as the treatment is costly, we advocate a more restrictive approach towards operations for mammary hypoplasia.

Connective tissue disease and other rheumatic conditions following breast implants in Denmark.

To investigate the risks of connective tissue diseases (CTDs) following breast implants we used the nationwide Danish Hospital Discharge Register (HDR) to identify 2,570 women who received breast implants, either for cosmetic reasons (N = 1,135) or for breast reconstruction (N = 1,435), between 1977 and 1992. Two additional cohorts of women having either breast reduction surgery (N = 7,071) or breast cancer without implants (N = 3,952) were identified for comparison. Observed-to-expected (O/E) cases of CTDs and other rheumatic conditions were calculated based on national hospital discharge rates. The calculated O/E ratio for definite CTDs was 1.1 (95% confidence interval [CI], 0.2-3.4) among women with cosmetic breast implants, and 1.3 (95% CI, 0.5-2.6) among women receiving implants for breast reconstruction. No CTD excesses were seen in the breast reduction or breast-cancer-without-implant cohorts. Statistically significant risks for muscular rheumatism (a nonspecific discharge diagnosis) were observed in all four patient cohorts: cosmetic (O/E ratio, 2.5; 95% CI, 1.7-3.6), breast reconstruction (O/E ratio, 2.5; 95% CI, 1.7-3.4), breast reduction (O/E ratio, 2.0; 95% CI, 1.6-2.3), and breast cancer without implants (O/E ratio, 1.4; 95% CI, 1.0-1.9). In conclusion, breast implants showed little association with definite CTDs. Breast surgery per so, however, was associated with an apparent increase in muscular rheumatism.

Cancer occurrence after cosmetic breast implantation in Denmark.

Most studies on cancer incidence after breast implantation have focused on breast cancer, while the risk of cancers at other sites has been less well investigated. We examined cancer incidence among 1,653 women who underwent cosmetic breast implant surgery at private clinics of plastic surgery in Denmark and 1,736 women attending the same clinics for other reasons during the period 1973-1995. Furthermore, we updated previously reported results among 1,114 women who received implants for cosmetic indications at public hospitals. All women were followed for cancer through the Danish Cancer Registry. In comparison with the general female population, the overall standardized incidence ratio (SIR) for cancer among women who received implants in private clinics was 1.65 [95% confidence interval (CI) = 1.17-2.27]. This elevated SIR reflected increased incidence ratios for almost all major cancer sites; however, only for non-melanoma skin cancer was there an excess of more than 2 cases. No significant excess of cancer was observed among women who received implants in public hospitals (SIR = 1.10, 95% CI = 0.76-1.52) or among women attending the private clinics for other problems (SIR = 1.10, 95% CI = 0.78-1.52). The SIRs for breast cancer after breast implantation were 1.1 (95% CI = 0.5-2.2) among private clinic patients and 0.9 (95% CI = 0.4-1.7) among public hospital patients. The overall findings of these 2 implant cohorts and results from other investigations suggest that cancer risk is probably not increased among women receiving cosmetic breast implants. The inconsistent results for private clinics and public hospitals are likely related to selection bias and confounding among the private clinic patients, but our data did not permit exploration of these possibilities. Further research into the determinants of these inconsistencies is warranted.
