In spite of the progress achieved in the field of toxicology and associated therapies, AlP is still responsible for a high rate of mortality due to the rapid onset of life-threatening symptoms, ineffective treatment and inadequate data on the efficacy of therapeutic interventions. AlP poisoning is a serious medical emergency demanding early and adequate management. In this prospective study of AlP toxicity, 44 patients admitted to emergency unit of Assiut university hospital in the period from 1st January to 30th June 2016 were included. There were 28 males (68.2%) and 16 females (31.8%). The majority of the cases were in the age group from 21 to 30 years (n=28, 54.6%). Thirty-six (81.8%) of admitted patients were from rural areas. Suicidal intake was the main mode of toxicity in 81.8% of cases. About 41% of the cases were shocked at their presentation and had metabolic acidosis. The mortality rate was 45.5%. The incidence of death in patients treated with N-acetyl cysteine to the incidence of death in non-treated patients was 1:12. AlP poisoning needs more attention due to associated fatality, the absence of an antidote, and a high number of youth victims. Supportive measures are vital in these patients. N-acetyl cysteine has a protective effect.","PeriodicalId":31692,"journal":{"name":"Arab Journal of Forensic Sciences Forensic Medicine","volume":"33 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80305980","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For this reason, to make diagnosis easier for forensic pathologists, there is a pressing need for the use of biomarkers. This article highlights biomarkers that can be used in the postmortem diagnosis of SCD. Cardiac troponins, high-sensitivity C-reactive protein, and creatine kinase-MB have proven to be very useful for this purpose. Lactate dehydrogenase, myoglobin and tumor necrosis factor α, although useful, are not efficient enough to be included in the list of biomarkers for the diagnosis of SCD. Previous studies have shown both positive and negative results for natriuretic peptides as a biomarker, and further studies are required to confirm its use as a biomarker for diagnosis of SCD in autopsy cases. In living subjects, a multi-marker strategy is useful in predicting risk of cardiovascular deaths. It is suggested that for the diagnosis of SCD, a multi-marker strategy may be more efficient. However, more studies are required to confirm this.","PeriodicalId":31692,"journal":{"name":"Arab Journal of Forensic Sciences Forensic Medicine","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72750009","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the associated secondary epidermal creases of fingerprints, fingerprint white line count (FWLC), has received less attention within the forensic community. This study was conducted with an aim to determine the potential of FWLC in sex inference among adult Nigerians. A cross sectional study was carried out with 150 males and 150 females with age range of 18-30 and 18-33 years, respectively. Live scanner (Digita persona, China) was used to capture the plain fingerprint for FWLC. Mann Whitney, Kruskal Wallis and logistic regression analyses were employed for determination of digit variation (based on side and type), sexual dimorphism and prediction models, respectively. Likelihood ratio and posterior probability were used to determine the favour odd for sex inference from FWLC. A significant higher mean value of FWLC was observed in females (2.24 ± 2.03) compared to males (0.85 ± 1.29). Absence of white line was indicative of male origin in all the digits except for left index digit (favor odd of 0.72 for females and 0.29 for males). However, FWLC from 5 to 11 were more likely to be of female origin. The best discriminator of sex was the left FWLC with a percentage accuracy of discrimination of 72%. The percentage contribution of the left FWLC in the discrimination of the sexes was observed to range from 23.0 to 30.20%. The FWLC was found to be a potential predictor of sex among adult Nigerians of Hausa ethnic origin.","PeriodicalId":31692,"journal":{"name":"Arab Journal of Forensic Sciences Forensic Medicine","volume":"50 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88340835","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, determination of metals in alcoholic beverages becomes a matter of utmost importance to forensic agencies. Many analytical techniques are available for qualitative and quantitative estimation of metals. Stripping methods can be used, and anodic stripping voltammetry proves to be a cheap, sensitive, reliable and less time-consuming method. With advancements in the field of electrodes, the sensitivity of voltammetry has greatly increased, making it an ideal analytical technique for the analysis of metals in wines and other alcoholic beverages. In the present review, an attempt has been made to critically review the various aspects of voltammetry with particular attention to stripping methods along with their application in determination of metal content in various alcoholic beverages.","PeriodicalId":31692,"journal":{"name":"Arab Journal of Forensic Sciences Forensic Medicine","volume":"23 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89552676","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study populations consisted of four hundred (n = 400) randomly selected sedentary and non-sedentary adult male subjects in the age group of 25 – 55 years, from the Nnewi community, who satisfied the inclusion criteria. They were grouped in three (3) groups consisting of Group A (25 – 35 years), Group B (36 – 45 years), and Group C (46 – 55 years). Out of which 207 were sedentary and 193 were non-sedentary subjects. Anthropometric parameters such as: weight (kg), height (cm), waist circumference (cm), hip circumference (cm), and mid arm circumference (cm), and cardiovascular parameters [systolic and diastolic blood pressure (mmHg)] were measured. Results showed a statistically significant increase in anthropometric and cardiovascular parameters in sedentary subjects compared to non-sedentary subjects. There was, however, a significant positive correlation of waist circumference (coefficient = 0.161) than hip circumference (coefficient = 0.158). Among sedentary subjects, only waist-to-hip ratio (WHR) had a significant positive correlation with diastolic blood pressure (coefficient = 0.181, p < 0.01). This study provides clear evidence that there is a linear relationship between physical activities and health status among individuals wich can help in forensic identification.","PeriodicalId":31692,"journal":{"name":"Arab Journal of Forensic Sciences Forensic Medicine","volume":"10 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73481433","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They are used to differentiate between ante-mortem and post-mortem drowning and to ascertain the site of drowning. However, to do so it is imperative to perform the diatomological mapping of water sources in different regions. The issue of localizing a drowning site may be resolved with the help of diatomological monitoring and mapping of the water sources, which generates substantial references for meeting the ‘criterion of concordance’. The present study has generated a database of diatom diversity in relation to different seasons and altitudes. Water sampling was made from low, mid and high altitudes during summer and autumn seasons. Important information was found after a microscopic examination of diatoms in water samples from different water bodies at different geographical altitudes. Twenty-seven diatom genera have been observed in the water samples from the selected localities. The findings of the current study have exposed the significant effect of seasonal changes and varied altitudes on occurrence of diatoms. A variety of commonly occurring site restricted diatoms were identified in the water samples. This useful information can be significant while investigating drowning cases from this particular region when the drowning site is either questioned or unknown.","PeriodicalId":31692,"journal":{"name":"Arab Journal of Forensic Sciences Forensic Medicine","volume":"5 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80567458","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
