Prior nonfatal firearm injuries in detainees of a large urban jail.

Detainees of large urban jails have may health risks including injuries related to violence and firearms. A survey of 582 randomly selected detainees entering the Cook County Department of Corrections during the summer of 1994 found that 51 percent had previously entered hospitals for violence-related injuries, and 26 percent survived prior gunshot wounds. Patterns of firearm injuries were different from patterns of violence affecting the general population. Factors common to those with prior firearm injuries included witnessing a shooting at an early age, tattoos, previous sexually transmitted diseases, easy access to a semiautomatic weapon, and prior incarceration. Implications and prevention strategies are discussed.

Thyrotropin binding inhibitory immunoglobulin (TBII) and thyroid diseases using ROC analysis.

At attempt to detect the auto-immune origin of hyperthyroidism may be made by measuring thyrotropin binding inhibitory immunoglobulin (TBII) which uses the antibodies ability to inhibit labelled TSH binding to the TSH receptor. This study was carried out on 196 patients of which 128 had autoimmune hyperthyroidism and 68 another thyroid disease. Construction of receiver operating characteristic (ROC) curves allowed us to show the quality of the assay. This method, according to the prevalence of the disease, helped to determine the ideal cut-off of the assay. This cut-off was between 13.5 and 7.5% for prevalences ranging between 10 and 80%. For a 9% cut-off, which corresponded to the group studied, we observed 87.5% sensitivity and 87% specificity. Existence of false positives and false negatives was linked to the assay method which only informed us about the occupation of the TSH binding site and not its physiological activity. However, we concluded this easy to perform assay is a good test for the diagnosis of autoimmune hyperthyroidism.

[The value of estimating the levels of amniotic insulin which come from the fetus in looking after diabetic pregnancies in the last trimester (author's transl)].

The authors carried out 49 estimations of amniotic fluid levels of insulin in 41 patients. 25 of these patients were non-diabetic and they were a control group, and 16 patients were diabetic (24 estimations). The liquor was collected by amniocentesis between the 32nd and the 42nd week of amenorrhoea. The mean of the control levels was 3.17 micro-units per ml. The mean of the values in diabetic pregnancies was 9.97 micro-units per ml. The difference between the two groups is statistically significant. We have studied this insulinaemia in relationship to the duration of the diabetes, the maternal weight increase, the levels of insulin used therapeutically, the blood glucose level, the rise in arterial blood pressure, the weight of the infant, the date of delivery, the presence of fetal distress and the control of blood sugar. There is a statistically significant difference between the insulinaemia of patients in whom the diabetes is well controlled (mean level of 7.08 micro-units per ml) and the patients in whom the diabetes is badly controlled (31.7 micro-units per ml). This new parameter for supervision of the third trimester of pregnancy in diabetics gives rise to the possibilities of a better approach to materno-fetal blood sugar regulation and to an adjustment of the therapeutic doses of insulin that are given which will result in lengthening of the duration of pregnancy, with the aim of achieving a spontaneous vaginal delivery at term.

[The level of glycohaemoglobin (Hb A1c) in connection with diabetes and pregnancy (author's transl)].

The authors worked out a normal curve using 379 levels obtained over 9 months in 180 normal pregnancies. 6% (with a confidence level between 4.4% and 7.6%) was usual for haemoglobin A1c. Then they compared 42 levels of glycohaemoglobin obtained from 14 pregnant diabetic patients where the mean value was 8.34%. Glycohaemoglobin A1c therefore is a good indicator or the level of stabilisation in diabetic pregnancies in the two months before the estimation is taken. It is therefore possible to think that it does indicate chronic hyperglycaemia and does seem to have a future in screening diabetic pregnancies. On the other hand it does not seem to be of any supplementary value in monitoring the fetus of the diabetic mother in the third trimester of pregnancy because of the small variations in the levels that are obtained as compared with the suddenness of fetal complications.
