Circumscribed low grade astrocytomas in the dominant opercular and insular region: A pilot study

Summary Intraoperative mapping techniques allow a reliable identification or exclusion of eloquent brain areas and are well tolerated by the patients. In dominant opercular tumours radical surgery can only be achieved without lasting deficits with intraoperative histological examination of the resection line and mapping. If an early post-operative MRI shows residual opercular tumour in non-eloquent areas re-operation is recommended.In large dominant insular or opercular-insular tumours only biopsy is recommended, because only an incomplete removal can be accomplished, because the trial of radical removal carries a high risk of postoperative deficits due to possible vascular damage of the lenticulo-striate arteries or internal capsule. Because subtotal removal of low grade gliomas does not increase the progression free interval, we would not recommend surgery in these cases, as they carry a significant risk of a further deficit.     

Nonexperimental evaluation of the effectiveness of a screening program for lung cancer.

The effectiveness of screening to control lung cancer was examined in the German Democratic Republic by analyzing data from a cancer registry and incidence and mortality rates for lung cancer relative to different screening policies, and by two case-control studies. Mortality from lung cancer did not appear to be affected by the screening programs studied. The high cost of mass screening, combined with uncertainty about the benefits of early treatment of lung cancer, outweigh the vague advantages of such screening.     

Ultrasonography in the detection of Achilles tendon xanthomata in heterozygous familial hypercholesterolemia.

We have examined the usefulness of ultrasound (US) in the detection of Achilles tendon (AT) xanthomata in heterozygous familial hypercholesterolemia. Our study is based on 30 adult subjects with heterozygous familial hypercholesterolemia (FH) (16 men, 14 women), 27 subjects with other non-familial forms of severe hypercholesterolemia (non-FH) with serum total cholesterol levels > or = 8 mmol/l (13 men and 14 women) and 31 subjects without marked hypercholesterolemia of the same age (control group; serum total cholesterol < 8 mmol/l) (15 men, 16 women). The three groups were comparable with respect to age, sex and body mass index. In the control group the mean sagittal thickness of AT was 4.5 mm (95% CI 3.2, 5.9 mm) and the mean coronal breadth of AT 11.0 (95% CI 9.0, 13.0 mm). Mean thickness of AT was 4.9 (range 4-7) mm in the non-FH group and 11.1 (5-16) mm in the FH group. The mean breadth of AT was in these groups 12.0 (10-17) mm and 19.2 (12-27) mm, respectively. Using the upper 95% confidence interval cut-off point in the control group as a criterion for normal AT thickness and breadth, 6 (22%) of non-FH and 29 (97%) of FH patients had increased AT thickness and 5 (19%) vs. 26 (87%) patients had increased AT breadth, respectively. The sensitivity of AT thickness for identifying FH was 0.97, specificity 0.78 and positive predictive value 0.83. The sensitivity of AT breadth in identifying FH was 0.87, specificity 0.81 and positive predictive value 0.84. None of the control subjects and none of the non-FH patients showed structural abnormalities of AT in the US, whereas 89% of FH-patients showed hypoechogenicity of AT. FH-score obtained by summing up the number of abnormal US findings gave a sensitivity of 0.93, a specificity of 0.96 and a positive predictive value of 0.96 for AT US in discriminating FH from non-FH. In conclusion, US examination of AT is a useful method in the detection of AT xanthomata and thus of help in the diagnosis of heterozygous FH.     

What Factors in Early Pregnancy Indicate that the Mother Will Be Hit by Her Partner during the Year after Childbirth?A Nationwide Swedish Survey

Abstract: Background : To be hit by one's intimate partner during the first year after childbirth may affect a woman's health and ability to take care of her newborn. The purpose of this study was to document the prevalence and indicators in early pregnancy of a woman being hit by her partner during the year after childbirth. Method : Information was collected by a postal questionnaire in early pregnancy and 12 months after childbirth from the approximately 5,550 women in Sweden who visited an antenatal care clinic for the first time during one of three chosen weeks in 1999 and 2000. Results : Of the 3,266 recruited women, 2,563 returned the follow‐up questionnaire. Being hit during the first year after childbirth was reported by 52 of the 2,563 (2%) women: 32 (61%) had been hit by their partner once, 12 (23%) twice, and 8 (15%) three or more times. Risk increased in women who were age 24 years or younger (3.9% had been hit), unmarried (7.1%), born in countries outside Europe (6.8%), with a partner born outside Europe (5.4%), had a low level of education (8.9%), and were unemployed (5.0%). In early pregnancy, women with back pain (4.0%), a chronic illness (4.1%), coital pain (6.1%), frequent depression‐related symptoms (8.1%), stomach pain (3.8%), or a urinary tract problem (6.3%) were hit more often than others after childbirth. Conclusions : At least 2 percent of Swedish women giving birth in 2000 were hit by their partner during the year after childbirth. Using identified predictors during antenatal care may increase the likelihood of finding women at risk, thereby enhancing the possibility of interventions to prevent this crime and health hazard.
