Nerium oleander is an ornamental evergreen shrub belonging to the family Apocynaceae. The Apocynaceae family includes the attractive evergreen shrub known as oleander. The cardiotoxic glycoside, oleandrin, is present in all portions of the common oleander plant. Oleander consumption can result in deadly situations accidentally or as a suicide attempt. After consuming kettle-boiled oleander leaf extract as part of a suicide attempt, an 80-year-old man was discovered comatose in his home and taken to our emergency room. The patient's heart rate was 30 beats per minute, and he had hypotension. Arterial blood gas analysis revealed remarkable metabolic acidosis and hyperkalemia (K: 7.7 mEq/L). An electrocardiogram showed a wide QRS wave, similar to a sine curve. The patient collapsed following cardiac arrest soon after hospital arrival. Veno-arterial extracorporeal membrane oxygenation was initiated; however, the patient eventually died. The serum level of oleandrin at hospital arrival, subsequently measured by LC–MS/MS, was found to be 33.4 ng/mL, far above the levels reported in previous fatal cases. 相似文献

Death From Butane Inhalation Abuse in Teenagers: Two New Case Studies and Review of the Literature 下载免费PDF全文
Véronique Alunni M.D. Ph.D. Yvan Gaillard Pharm.D. Ph.D. François Castier MD. Marie‐Dominique Piercecchi‐Marti M.D. Ph.D. Gérald Quatrehomme M.D. Ph.D. 《Journal of forensic sciences》2018,63(1):330-335
The ready availability of butane makes butane abuse frequent. Fatalities are rare. This study presents two cases of death by butane overdose. The postmortem analyses were carried out using headspace gas chromatography–mass spectrometry. It revealed femoral blood butane concentrations of 18 and 22 mg/L, respectively, as well as specific combinations of adjuvants in each victim. In one of the victims, brain and fatty tissue also contained butane, pointing to chronic consumption. The originality of this study is to show that the identification of specific combinations of adjuvants can be helpful for identifying the brand of deodorant used. Also, sampling the skin and mucosa can help identify the method of drug delivery. The histological examination documented both the direct toxic effect of the gas on the respiratory mucosa and signs of chronic abuse. Volatile substance intoxications should be systematically considered in case of sudden death in a teenager. 相似文献

Abstract: A 22-year-old man was found dead after he had continued to sit on a reclining chair for 2 years. He had consumed an unbalanced diet, kept wearing the same pair of socks and never washed himself for the term. His skin of bilateral crura developed into elephantiasis with severely festered ulcers on its surface. At autopsy, subcutaneous edema was significant in his lower limbs, and chronic circulatory disturbance of lymphoducts and veins was observed histologically. There were no crucial findings to account for chronic edema in the lower limbs. It has been reported that maintaining a seated posture obstructs both lymphoducts and veins because of bending the groin, decreases their return flow by inducing muscular atrophy, and causes subcutaneous edema in the lower limbs. Oligotrophia and dirt on his limbs might have exacerbated the chronic edema in elephantiasis. We concluded that a long-term abnormal life-style had caused fatal elephantiasis. 相似文献

Two autopsy cases, where the individuals were suspected of having ingested acephate, an organophosphorous insecticide, are reported. Acephate and its active metabolite, methamidophos (MP), were analyzed in the biological fluids by GC/MS, using the salting out method with liquid-liquid extraction columns. The first case was that of a 70-year-old man whose blood acephate was 149 microg/mL, and MP was 3.0 microg/mL. Serum pseudocholinesterase (ChE) activity was inhibited. No remarkable finding of injury or disease was determined as the cause of his death, but acute poisoning by acephate was mostly suspected. The second case was that of a 60-year-old man. A deep gash in the left neck injured the left common carotid artery in addition to the severely ischemic state of the primary organs. His blood acephate was 46 microg/mL, and MP was not detected. ChE activity was in the normal range. Hemorrhage was mainly suspected as the cause of his death. The concentrations of acephate and MP in human blood after oral ingestion are first reported here, and the acute toxic level of acephate is discussed. 相似文献

Rapid and simple sex determination method from dental pulp by loop-mediated isothermal amplification
Hiroaki Nogami Hirofumi Tsutsumi Toshinobu Komuro Rei Mukoyama 《Forensic Science International: Genetics Supplement Series》2008,2(4):349-353
Sex determination from dental pulp DNA was examined by loop-mediated isothermal amplification (LAMP) method. Amelogenin locus was analyzed for sex determination. A set of four specially designed primers was prepared based on database from Gene Bank, and loop primers were designed to shorten the analysis time. Analysis was performed using 32 dental pulp DNA samples removal from permanent teeth stored at room temperature for 1–25 years after extraction. The X allele was detected in approximately 32 min with real-time turbidimeter and the Y allele was detected in approximately 34 min. Analysis time was reduced to half when using loop primers. Visual detection was also possible as the amplified product showed white turbidity. Sex determination by LAMP method was rapid and simple, and it should prove useful in unknown bodies of mass disasters. 相似文献

Since 2017, complaints of sexual violence have increased in France. At the same time, the management of sexual offenders has been at the center of international public health policies. The prevalence of mental disorders among sexual offenders is an essential field of research. There are some published studies on the prevalence of psychiatric disorders in sexual offenders in detention, but there are few recent published studies among French individuals who were detained. Our objectives were to determine the prevalence of psychiatric disorders among persons detained for sexual offenses and the level of care received according to their diagnosis. For this purpose, we carried out a retrospective observational study from January 2017 to October 2021 of all adult sexual offenders, whether accused or convicted, who were seen in the psychiatric consultation unit of Les Baumettes prison, Marseille, France. The primary outcome measure was the psychiatric diagnosis entered in the medical records. One hundred forty-two patients were included in analysis. All patients were men, and the majority (n = 97, 68.3%) of these patients presented with at least one psychiatric disorder, principally a personality disorder (31.7%). 10.6% presented with a schizophrenic disorder, 4.9% a bipolar disorder, 3.5% a depressive disorder, 5.6% pedophilic paraphilia, and 25.4% an addictive disorder. Their management and comorbid addictions were analyzed in subgroups for each psychiatric disorder. Patients appeared to receive an appropriate level of care for their diagnosed disorder. It seems important to develop structured assessment of recidivism risk for better management of sexual offenders. 相似文献
