Toxicological findings in a multi-drug death involving propoxyphene, caffeine, phenacetin, acetaminophen and salicylate

The toxicological findings of a multi-drug related fatal poisoning are described here. A 35-year-old Caucasian male found dead on the kitchen floor was a known user of abused drugs and had been taking aspirin alone or in combination with phenacetin and caffeine for the relief of joint pains. The gross examination of the organs at autopsy revealed slight grooving of the uncus and various stages of necrosis in the renal papillae. Histological examination confirmed the gross appearance of pulmonary congestion and edema, cerebral edema and interstitial nephritis of the tubules. Toxicological evaluation of the blood and urine samples disclosed the presence of propoxyphene (51 and 250 mg/l), salicylate (185 and 2750 mg/l), caffeine (16 and 37 mg/l), and phenacetin (9.6 and 20 mg/l). Furthermore, acetaminophen also was present in the plasma (54 mg/l) and urine. A gas liquid chromatographic method for simultaneous analysis of phenacetin and caffeine utilizing a nitrogen phosphorus detector was proposed.     

Mandibular canine index--a clue for establishing sex identity

A preliminary study for establishing sex identity by Mandibular Canine Index is described. Seven hundred and sixty six individuals from a South Indian population of either sex, ranging in age from 15 to 21 years, with fully errupted, healthy and non-worn mandibular permanent canines were studied. The data collected was analysed statistically. Accurancy of sex determination identity was found to be 84.3% in the male and 87.5% in the female. The method is simple and inexpensive to conduct and therefore can be applied in Forensic Odontology, as a method for establishing sex identity.     

A modified Gustafson method of age estimation from teeth

Modifications to the Gustafson method of age estimation from teeth are described. They are designed to minimise the subjective nature of the scoring technique and to quantify the regressive changes in the enamel, dentine and cementum. Randomly selected teeth from 25 Indians were examined by the Gustafson method and by our own modification. It was shown that our modified method resulted in more accurate and reproducible age estimations than did the original method.     

The forensic significance of conjunctival petechiae

Conjunctival petechiae were mentioned in 227 (4.5%) of 5,000 consecutive autopsy reports of the Dade County Medical Examiner Department. They were most frequently observed in those who had died natural deaths (particularly due to cardiovascular disease), followed by those who had died from asphyxia, head injury, and central nervous system disorders. The incidence of conjunctival petechiae in victims of homicidal asphyxiation was 78%. These data suggest that conjunctival petechiae most often are the result of hypoxia coupled with an acute increase in cephalic vascular pressure. The latter factor may be the consequence of mechanical vascular obstruction or acute right heart failure.     

Separation of overlapping fingermarks by Matrix Assisted Laser Desorption Ionisation Mass Spectrometry Imaging

Latent fingermarks are impressions of the skin ridge pattern that are transferred by the accidental contact of fingertips with a deposition surface. The ability to enhance, lift and produce an image of a latent fingermark, for comparison and suspect match against a central fingerprint database, provides forensic investigators with what is still considered one of the most powerful means of biometric identification to date. Identification relies on the recovery, visualisation, extraction and comparison of local characteristics of the ridge pattern (minutiae) that are unique to individuals. Therefore, both for manual inspection of the minutiae and using automated ridge extraction algorithms, the clearer the ridge details, the more reliable and successful the match. Overlapping fingermarks pose a remarkable challenge in this context and are often encountered when developing marks from crime scenes. Here we propose the use of Matrix Assisted Laser Desorption Ionisation Mass Spectrometry Imaging (MALDI MSI) to separate overlapping fingermarks using ion signals that are characteristic of each fingermark and that may be endogenous or exogenous in nature. In this work we show that the methodology works in a number of different scenarios both using manual inspection of the spectrum profile or a much quicker multivariate statistical analysis.     

《大国政治的悲剧》与米尔斯海默的悲剧

约翰.米尔斯海默的《大国政治的悲剧》确实是一个悲剧,它是米氏带着悲观主义有色眼镜审视国际政治的必然结果。米氏自身天生的悲观主义来自于他的文化背景、经历和美国学者的心理优势。
