Detection of semen in stains on material evidences by quantitative immunofluorescence test

Russian and foreign methods used in forensic medicine for detection of the semen in stains on material evidences are compared. The potentialities of quantitative immunofluorescence test for detection of the semen in stains on material evidences, developed at Bureau for Forensic Medical Expert Evaluations of the Leningrad region, are described. Unlike other methods used in Russia, this method detects the semen in stains in the absence of spermatozoa and in stains with very low amount of the semen. Our modification allows objective recording of the results with computer processing. The method is cheaper than its foreign analogs and its sensitivity is similar to them.     

Asphyxial death during prone restraint revisited: a report of 21 cases

Determining the cause of death when a restrained person suddenly dies is a problem for death investigators. Twenty-one cases of death during prone restraint are reported as examples of the common elements and range of variation in these apparently asphyxial events. A reasonable diagnosis of restraint asphyxia can usually be made after ruling out other causes and collecting supportive participant and witness statements in a timely fashion. Common elements in this syndrome include prone restraint with pressure on the upper torso; handcuffing, leg restraint, or hogtying; acute psychosis and agitation, often stimulant drug induced; physical exertion and struggle; and obesity. Establishing a temporal association between the restraint and the sudden loss of consciousness/death is critical to making a correct determination of cause of death.     

Sudden infant death, large intestinal volvulus, and a duplication cyst of the terminal ileum

A previously well 7-week-old boy was found unresponsive and cyanotic in his cot in the morning. Resuscitative attempts achieved only partial response with subsequent terminal cardiac arrest occurring later in the day. At autopsy a large intestinal volvulus was found associated with disseminated Clostridium perfringens sepsis. In addition, a duplication cyst of the terminal ileum was present. Although rare, right-sided colonic volvulus may be a cause of unexpected death in infancy. While predisposing factors to volvulus may include intestinal duplication cysts, the anatomic relation of the duplication to the volvulus must be carefully determined before a causal relation can be accepted; the cyst in this case was most likely incidental to the terminal event.     

Unexpected childhood death due to hemolytic uremic syndrome

Two cases of unexpected childhood death due to hemolytic uremic syndrome are reported. A 21-month-old girl who was discovered dead in bed following a short illness was found at autopsy to have overwhelming sepsis resulting from transmural colitis. Escherichia coli serotype 0157A was isolated from the intestine, and renal changes of hemolytic uremic syndrome were found. A 4-year-old girl died suddenly in hospital from intracranial hemorrhage while being treated for hemolytic uremic syndrome-related renal failure. Culture of urine and feces grew verocytotoxin producing E. coli. These cases demonstrate that hemolytic uremic syndrome may be a rare cause of unexpected childhood death and that the diagnosis may not be established prior to autopsy. Postmortem culture of tissues and fluids in cases of suspected sepsis in children may be essential in establishing this diagnosis, because histologic evaluation may be compromised by profound sepsis and tissue putrefaction. Accuracy in diagnosis may have significant public health and medicolegal consequences.     

Pathologic features of childhood pedestrian fatalities

A retrospective analysis of 68 cases of fatal childhood pedestrian accidents in South Australia that occurred over a 20-year period from January 1977 to December 1996 was undertaken. The age range was 12 months to 16 years (average, 7.6 years), with a male to female ratio of 41:27. The most common site of significant injury was the head (91.2%), followed by the abdomen (50%), chest (47.1%), and neck (38.2%). The most frequently encountered significant injury combinations involved the head, chest, and abdomen (14.7%); the head and chest (11.8%); and the head, neck, and abdomen (11.8%). Injuries were severe, consisting of extensive compound and comminuted skull fractures, neck fractures, and massive intraparenchymal brain and internal organ damage with avulsions and fragmentation. Non-life-threatening limb injuries occurred in 88% of cases. A distinct subgroup involved infants and younger children playing in driveways at home who were hit by reversing vehicles. The injuries were often of such a severe nature that death was instantaneous and with no possibility of successful medical intervention. More deaths occurred during the winter than summer months.     

Persian leopard (Panthera pardus) attack in Oklahoma: case report

The authors report a fatal case of a Persian leopard (Panthera pardus) attack in an animal sanctuary in Oklahoma. The victim was a 53-year-old Costa Rican woman who was attempting to feed the animal when she was attacked and killed. Autopsy, radiography, fingerprint analysis, microbiologic cultures, and dental impressions were used to evaluate the case. These simple techniques can be applied to similar cases involving wild and domestic animal attacks.     

Lawyers' Questioning: The Effect of Confusing Questions on Witness Confidence and Accuracy

The present study investigated the effect on witness confidence and accuracy of confusing questions often used by attorneys in court. Participants viewed a videotaped film and were individually questioned about the incident 1 week later. Half the participants were asked questions using six categories of confusing questions (negatives, double negatives, leading, multiple questions, complex syntax, and complex vocabulary); the remaining half were asked for the same information using simply phrased equivalents. Confusing questions reduced participant-witnesses' accuracy and suppressed confidence–accuracy relationships compared with the condition where simplified alternatives were asked. Witness performance was impaired by the fact that mock-witnesses rarely asked for a confusing question to be explained or qualified their answers. This experiment demonstrates the importance of ensuring that lawyers ask witnesses simple, clear, questions.     

The pregnant woman and the good Samaritan: can a woman have a duty to undergo a caesarean section?

Although a pregnant woman can now refuse any medical treatment needed by the fetus, the Court of Appeal has acknowledged that ethical dilemmas remain, adverting to the inappropriateness of legal compulsion of presumed moral duties in this context. This leaves the impression of an uncomfortable split between the ethics and the law. The notion of a pregnant woman refusing medical treatment needed by the fetus is troubling and it helps little simply to assert that she has a legal right to do so. At the same time, the idea that a pregnant woman fails in her moral duty unless she accepts any recommended treatment or surgery--however great the burden--is also not without difficulty. This article seeks to find a way between these two somewhat polarized positions by arguing that, instead of being a question primarily about whether legally to enforce moral obligations, the 'maternal-fetal conflict' begins with previously unrecognized difficulties in determining when a woman's prima facie moral rights invoked in the treatment context should 'give way' to the interests of the fetus. This difficulty is mirrored within the law. Thus, how can we tell when a pregnant woman has the moral or legal duty to submit to a caesarean section? Seen in this way, the conflict is a problem which lies at the interface between moral and legal rights and duties, showing that there are important conceptual links between the ethics and the law. Against this background, this article explores the limits of a pregnant woman's right to bodily integrity by focusing upon the idea of her moral duty to aid the fetus through her body. Here we find difficulties in determining the existence and extent of this somewhat extraordinary duty. Such a duty is contrasted with both negative and positive duties toward others in the course of 'general conduct.' Attention to the social context of pregnancy and the refusal of treatment within this is also instructive. Overall, the purpose is to foster understanding and acceptance of the current legal position.
