Inhibition of insulin release after passive transfer of immunoglobulin from insulin-dependent diabetic children to mice.

We used the mouse passive transfer model to test whether islet cell antibodies affect beta-cell function. The immunoglobulin (Ig) fraction of plasma from 5 islet cell surface antibody-positive, newly diagnosed insulin-dependent diabetic children or of a pool of plasma from 12 normal subjects was injected daily (7-16 mg IgG/day) for 14 days into normal immunosuppressed BALB/c mice. Insulin secretory responses in the Ig-injected mice were then examined by perfusing the rodent pancreata in vitro. Insulin release induced by 20 mmol/liter D-glucose during 30 min of stimulation decreased from 900 ng insulin (median; range, 814-1138) from pancreata of mice injected with control Ig to 511 ng (range, 130-786) from pancreata of mice injected with diabetic Ig (P less than 0.003). Both the initial peak and the sustained second phase of glucose-stimulated insulin release were depressed in 4 of the 5 pancreata from mice injected with diabetic Ig. These results indicate that circulating antibodies in diabetic children may alter beta-cell function and possibly contribute to the pathogenesis of insulin-dependent diabetes.

[Fatal child abuse (caused by physical violence) in Germany during 1 January 1985 to 2 October 1990. Results of a multicenter study].

UNLABELLED: No reliable data are available on cases of lethal child abuse (by active force) in the area of Federal Republic of Germany prior to reunification (the former West Germany). In a multicenter study we therefore examined the police and court records for such cases occurring in the period 1 January 1985 to 2 October 1990 in nearly the entire area of Federal Republic of Germany. RESULTS: The study center received information on 58 cases of lethal child abuse. Extrapolated to all institutes of legal medicine, this corresponds to 62 cases in all of West Germany in the period studied. An approximately equal number of unreported cases should be added to this figure. Including unreported cases, at least 20 cases of lethal child abuse occurred per year; thus only one in every two cases ever came to light. Almost two thirds of the victims were younger than one year old. At autopsy 59% exhibited signs of repeated abuse at autopsy. By far the most common cause of death was direct impact from a blunt object, usually to the head. Mostly, the male person to whom the victim relates most closely (father, stepfather, partner of the mother) has killed the child. Twenty-one of the 74 persons charged saw the charges against them dropped or were acquitted due to lack of evidence; 51 received sentences ranging from one year probation to life. In the remaining two cases the outcome of the trial was unknown. Signs of abuse were readily apparent at autopsy in almost all cases. The high number of unreported cases underscores the need to educate medical students and practicing physicians to be on the look-out for signs of abuse and argues for an increase in the rate of autopsy.

[Fatal child neglect in West Germany 1 January 1985 to 2 October 1990. Results of a multicenter study].

UNLABELLED: Up to now reliable data were available on cases of lethal child neglect in the area of the Federal Republic of Germany prior to reunification (the former West Germany). In a multicenter study we therefore examined the police and court records for such cases occurring in the period from 1 January 1985 to 2 October 1990 in nearly the entire area of Federal Republic of Germany. RESULTS: The study center received information on 19 cases of lethal child neglect. Extrapolated to all institutes of legal medicine, this corresponds to 20 cases and thus 3.5 cases a year in the whole of West Germany in the period studied. There is to be added a dark-field which cannot be limited more precisely. However, the cases of fatal child neglect might have occurred much more seldom than fatal child abuse caused by use of physical violence. Slightly more than half the victims were younger than 1 year, the oldest one was 7 10/12 years old. Most frequently the children died of starvation and thirst. Mostly the mothers/nursing mothers killed the child alone or together with the victim's father/stepfather. In the majority of the cases there was not a close affection between parents and child. Nearly 30% female/male perpetrators suffered from chronic alcohol abuse. Only 15 (= 56%) of 27 female/male perpetrators were sentenced to imprisonment (period between 7 months on probation and 10 years). Mitigation circumstances existed for nearly half the persons sentenced to imprisonment. It is true that child neglect is a rarer crime, but the experts of legal medicine always have to indicate errors made during the external inspection of the corpse (among others failures to see indications of neglect).

[Sudden fatalities in mechanically restrained patients].

We report on 7 nursing home or hospital patients who died suddenly and unexpectedly during physical restraint. Four of the patients were found dead hanging beside their beds, with their waist restraints displaced to the thorax. In spite of a variety of preexisting diseases, asphyxia by thorax compression was the most probable cause of death. Three other patients, when falling out of their beds, were strangulated by the head opening of a nursing bedcover fixed to the bed. In all instances the fatal accidents resulted from improper handling of the restraint devices, namely from the omission of bed rails as well as of the obligatory waist belt lateral fixations. The bedcover type involved in three fatalities is destined for care purposes but not licensed as a restraint device. Physical restraint fatalities can be avoided to a large extent if the producers' instructions are strictly observed, and only especially trained and supervised personnel is admitted to this field of duties.
