Abnormal organ weights often serve as an indicator of underlying disease or other pathological process making assessment of organ weight a critical part of the autopsy examination and interpretation. Unfortunately, normal organ weights for children are often based on studies done in the 1930s and 1960s. Thus, the present study was designed to accurately assess organ weights in children to establish reference ranges for use in autopsy examinations. A total of 1759 traumatic deaths in children aged 0 to 12 years were reviewed. Analysis revealed that body length was the best predictor for organ weight. Reference ranges were established and stratified by both age and body length.
We present the case of a male adult who was admitted to an emergency department after having sustained envenomation from a black mamba (Dendroaspis polylepis). According to the available history, a single fang hooked his right index finger, post venom extraction. After administering antivenom in the accident and emergency department, further vials were transfused in the intensive care unit. An urticarial rash was noted, which was thought to be related to the antivenom. The victim remained in a coma for 3 days, after which he was declared dead. A medicolegal postmortem examination was performed 4 days after death because of logistical reasons. The complexities of differentiating acute envenomation from black mamba versus early acute reactions to polyvalent antivenom administration are highlighted in this case study.
Schizophrenia is a detrimental psychiatric disorder, with an increased mortality from natural and nonnatural causes.
This study was a retrospective review of autopsy cases of all the individuals with history of schizophrenia investigated by the Office of the Chief Medical Examiner, State of Maryland, for a 5-year period from 2008 to 2012.
A total of 391 schizophrenia patients were autopsied at the Office of the Chief Medical Examiner because they died suddenly and unexpectedly. Their age ranged from 15 to 100 years with the mean age of 49.5 years. Of the 391 deaths, 191 (48.8%) were white, 185 (47.3%) were African American, and 15 (3.9%) were either Hispanic or Asian. The male and female ratio was 1.5:1. The majority of deaths (64.2%) were caused by natural diseases, 12.0% deaths were accidents, 11.5% deaths were suicides, and 9.7% deaths were homicides. The manner of death remained undetermined in 38 cases (9.7%). Of the 251 natural deaths, 198 cases (78.9%) were owing to cardiovascular diseases. Cause of death was listed as cardiac arrhythmia in 11 cases. This diagnosis of cardiac arrhythmia was made by exclusion based on death scene investigation, review of medical history, complete autopsy, and toxicological tests. Drug intoxication was the second most common cause of death.
The study shows high fatality caused by cardiovascular diseases and drug intoxication among schizophrenia patients, which calls attention of the medical community to closely monitor the high risk factors of sudden death among schizophrenia patients.
Barotrauma-associated perforation of the colon is not common and usually occurs due to the passage of compressed air through the anus. Most of the cases are accidental and done for fun often at the victim's workplace. Therefore, it is necessary that the workers should be made aware of the dangers of the equipment they regularly use at their workplace. Here, we describe one such case where a rice mill worker died when compressed air through an air pump pipe entered his rectum. His chief complaint was abdominal pain and breathing difficulty. Computed tomography scan of the abdomen and thorax showed pneumoperitoneum, pneumomediastinum, and soft tissue emphysema. There was a complete tear in the rectosigmoid junction of the colon. The mucosa was deeply hemorrhagic and congested. Histopathology of this segment showed hemorrhagic necrosis of the mucosa.
President Kennedy sustained 2 gunshot wounds on November 22, 1963, in Dallas, Texas, while riding in the right-rear seat of the presidential limousine. The convertible top was down, and no special ballistic protection for the occupants was present.
The ballistic events in the assassination and subsequent ballistic evidence were not fully understood then and continue to be misunderstood and often misrepresented today. These facts are largely the consequence of the very uncommon wound ballistic properties of the 6.5-mm Carcano bullets associated with the President's gunshot wounds and the visual responses of the President to his 2 gunshot wounds so often viewed in the 8-mm Zapruder film.
An understanding of the wound ballistic characteristics associated with the John F. Kennedy assassination also applies to certain contemporary bullets. Such an understanding could assist forensic pathologists in future cases in evaluating and correctly interpreting gunshot wounds associated with these types of bullets.
Postmortem tryptase is a useful biochemical test to aid the diagnosis of anaphylaxis. Multiple perimortem and postmortem factors have been documented to cause an elevation in postmortem tryptase level. One factor that was recently recognized to have an impact on postmortem tryptase level is correct sampling technique. A recent study recommended aspirating blood samples from a clamped femoral/external iliac vein to be used for reliable postmortem tryptase analysis. This study sampled 120 consecutive nonanaphylactic deaths in which all the peripheral bloods were sampled as recommended. Postmortem interval, resuscitation, different nonanaphylactic causes of death, sex, and age did not show any statistical significant relation to postmortem tryptase level in Student t test, Pearson correlation, and univariate and multivariate analyses. The mean (SD) postmortem tryptase level was 8.4 (5.2) μg/L (minimum, 1.0 μg/L; maximum, 36.1 μg/L; median, 7.3 μg/L). Using nonparametric methods, the postmortem tryptase reference range in nonanaphylactic death was established as <23 μg/L (97.5th percentile).
The autopsy maintains its significance both forensically and medically despite enormous developments in antemortem and postmortem diagnostic methods. The present study probes the knowledge, attitude, and behavior of religious officials in our city toward autopsy and make an evaluation of how religion and culture affect those factors.
The study consists of 219 Imams (male) and 69 Quran instructors (female) who serve in urban and rural regions of Kahramanmaras and approved informed consent forms.
Two hundred thirty (79%) of the participants stated that the autopsy was an appropriate process according to Islam; 1 (0.3%) stated that it was inappropriate, whereas 57 (19.8%) were observed to have no idea regarding its appropriateness.
The mean knowledge score that participants had about autopsy was determined to be 7.45 ± 1.73 (min = 1, max = 10).
On the other hand, 240 participants (83.3%) stated that it was important for the religious officials to inform the society about the autopsy.
The negative attitude toward autopsy stems from the lack of knowledge and traditions. The religious officials could help the doctors to change the negative attitude stemming from tradition toward the autopsy.
The materials used to produce shotgun ammunition can have different properties depending on the purpose, and ammunition can be fabricated or loaded manually. In Turkey, wheat-loaded cartridges are manufactured for use as sound cartridges. This ammunition is understood by the public to be harmless. However, we present a case of a 13-year-old adolescent boy who was wounded from a contact shot to the chest. An entrance wound measuring 7 cm and 5 cm in diameter was seen on the skin. Wheat grains could not be detected in the internal organs and were only observed between the chest muscles around the entrance wound. A plastic wad was also found in this area. The cause of death was internal bleeding due to internal organ injury. Wheat-loaded cartridges are not visible on x-ray and are difficult to detect visually in the wound.
The authors report on the autopsy case of a 40-year-old primigravida without either coagulation disorders or anticoagulant/antiplatelet therapy, who developed a fatal intracranial subdural hematoma after spinal anesthesia (SA) for elective cesarean delivery for tocophobia.
Intracranial subdural hematoma is the most dreaded complication of SA and is often misdiagnosed with postdural puncture headache.
In this article, the authors discuss pathophysiological mechanisms and risk factors for the development of an intracranial subdural hematoma after SA and review the pertinent literature.
Forensic pathologists are requested to select matrices alternative to blood in cases of toxicological interest in which blood is not available for different reasons. We evaluated morphine concentrations in blood, bile, and liver samples in 52 cases of heroin overdoses, relating them to each other, to understand the information that could be derived from their analysis. Gas chromatography/mass spectrometry analysis was performed for all the samples positive on screening for opiates. Shapiro-Wilk test, nonparametric Mann-Whitney test, linear regression analysis, and Bland-Altman test were used for analysis. Linear regression demonstrated that there was not a statistically significant association in morphine concentrations between blood and bile and blood and liver. Mean liver/blood ratio was 2.76, varying from 0.131 to 13.379, and bile/blood ratio was 28.79, varying from 0.28 to 559.16. According to these results, bile analysis is a “screening test”; biliary or hepatic concentration of morphine cannot provide information on hematic concentration at the time of death, having no forensic value taken individually.
