摘要:
Two unusual suicides of a 19-year-old white man and a 47-year-old white man, involving propane inhalation and plastic bag suffocation, are described. The special characteristics of propane gas as an asphyxiant agent are discussed, as well as its effect on the human body. The discussion emphasizes the postmortem examination and the collection of samples for toxicologic analysis.

摘要:
A case of attempted suicide by injection of elemental mercury is described. Radiographs demonstrated the presence of widespread opacities of metallic mercury in both the lungs and the abdomen. During a 5-year follow-up, even though the patient had high concentrations of mercury in the urine and blood, only mild clinical symptoms and moderate carbon monoxide diffusing capacity reduction appeared. No biochemical evidence of damage to any organ was found.

摘要:
The level of degradation of DNA as a means for determining the time of death has been proposed as a valid adjunct to the classic thanatochronologic methods. The twofold aim of this work was to determine which organ might reveal both a correlation between the percentage of degradation of the DNA and the time lapse since death, and would be easiest to sample and yield the most reproducible results even in technically unfavorable situations such as on-the-spot investigations at the scene of death. A comparison of the spleen, blood, and liver showed that hepatic tissue best meets these specific needs because it shows a virtually linear correlation between the time elapsed since death and the level of degradation of the DNA, and it can easily be sampled at the scene of death by use of a common biopsy needle.

摘要:
The utility of Y-STR haplotype and mtDNA sequence in personal identification from human remains is demonstrated. In five cases, severely damaged human remains were identified by Y-chromosomal short tandem repeat (STR) (Y-STR) haplotyping and mitochondrial DNA (mtDNA) sequencing. DNA was extracted from highly adipoceratous tissues using the phenol-chloroform method and polymerase chain reaction amplified for Y-STR haplotyping and sequencing of two hypervariable regions, HV1 and HV2, of the mtDNA. The authors also profiled the Y-STR haplotype and mtDNA sequence of a blood sample that was obtained from the presumptive brother of the decedent. Y-STR haplotyping and mtDNA sequencing results were compared with one another and with the Anderson sequence. It was concluded from these data that the lower part of the body (Case 1), the human head (Case 2), the upper part of the body (Case 3), and the right arm (Case 4) were from the same individual, whereas another lower part of a body (Case 5) was from a relative of the presumptive brother. A novel descriptive way of a statistical characteristic, gene or haplotype diversity, is shown.

摘要:
Gene and genotype frequencies in relation to the D3S1358, vWA, FGA, TH01, TPOX, CSF1PO, D5S818, D13S317, and D7S820 loci were determined in a sample of 290 unrelated individuals (204 Caucasians and 86 mulattoes) living in the city of São Paulo, Brazil. The sex test Amelogenin was also performed in all subjects from our sample, revealing the expected sex in all instances. Allele frequency data obtained from the analysis of these samples were in the usual range of other population groups with similar racial background. In the sample of Caucasian individuals, panmictic proportions were ruled out in relation to TPOX and CSF1PO loci, but only in the latter was the overall frequency of heterozygotes significantly less than expected. In the sample of mulattoes, Hardy-Weinberg proportions were rejected in relation to FGA and CSF1PO loci, but in no instance were the overall numbers of heterozygotes different from the corresponding expected ones under panmixia. Taking into account all this and also the number of tests performed, the degree of genetic heterogeneity of Brazilian populations, and the critical level reached by the significant results (1% < &agr;<5%), the departures from panmixia here observed can be considered to be negligible in altering significantly biologic relationship odds calculated under the assumption of random matings.

摘要:
A new method for better recovery of DNA suitable for amplification of hypervariable loci from fragments of teeth, consisting of two steps—scraping and aspiration, and extensive decalcification–is reported. Higher yields of high molecular weight DNA were obtained from the root, pulp, and crown of all kinds of 120 teeth, irrespective of gender, age, and source of teeth. HLA DQA1, 5 poly markers (LDLR, GYPA, HBGG, D7S8, and Gc), and other 12 short tandem repeat loci (HPRTB, F13B, LPL, D13S317, D7S820, D5S818, D21S11, D18S51, FGA, D8S1179, D3S1358, and vWA) could be successfully amplified and typed from recovered DNA.

摘要:
An unusual case of choking is presented. In this case, a 45-year-old man, while fishing and drinking with friends, attempted to swallow a whole fish. He subsequently asphyxiated as a result of upper airway obstruction.

摘要:
An accidental atypical hanging with the collar of a sweater is reported. A 67-year-old man was found dead in the sitting position with the collar of his sweater hanging off the brake handle of a motorcycle. Autopsy findings revealed a ligature mark on the surface of the neck; hemorrhages in the sternohyoid muscles; submucosal hemorrhages in the left greater horn of the hyoid bone; a large degree of submucosal petechial hemorrhages in the larynx, oral mucosa, and palpebral conjunctivae; and dark-red liquid blood with little clotting in the heart cavities. The alcohol levels in the blood and urine were 2.84 mg/ml and 3.52 mg/ml, respectively. It was concluded that the man had died from hanging by the sweater, and it was speculated that when he became inebriated, he might have lost consciousness and then fell with the collar of his sweater hanging from the brake handle of the motorcycle.

摘要:
This survey presents several cases of sudden deaths in Africa, specifically in Cote d’Ivoire, where the postmortem diagnosis of human cerebral malaria was determined after autopsy followed by pathologic examination of the brain. It is thought that cerebral malaria may be the primary cause of sudden death in nonimmunized persons during or after traveling in such endemic areas of Africa. The target population is composed of tourists, business travelers, and sailors. Because death caused by cerebral malaria occurs so suddenly, it can lead to forensic issues. Therefore, in any cases involving sudden death, it is very important for the forensic scientist to do a systematic evaluation, including pathologic examination of brain tissue, to rule in or exclude cerebral malaria. This practice will reinforce and aid research in progress directed at developing a vaccine and elucidating the role of tumor necrosis factor in this disease. Furthermore, this study will alert the physician to the importance of an effective and well-followed prophylaxis.
