Determination of sex is one of the most important and vital steps in forensic medicine. Sexual dimorphism using odontometric analysis is found to vary in different populations making it necessary to attain values of a specific population which makes identification of person as easy as possible. The present study aims to establish sexual differentiation using dental parameters including dental linear dimensions and indices. Maxillary jaw casts from total of 100 subjects (50 males and 50 females) between ages 17 and 24 years were taken. Mesiodistal (MD) and Buccolingual (BL) dimensions of each tooth of from maxillary jaw cast excluding third molar were measured using precision calipers, dental indices were calculated. Data was collected and statistical analysis was done using SPSS software version 20. Bucccolingual dimension was proved to be a better parameter than MD for assessment of gender in case of left central incisor, canines and left first molar. Crown index of right central incisor, second premolars, and left first molars was the best index for sex prediction of most of the teeth.
性别鉴定是法医学中最重要、最关键的步骤之一。使用牙齿测量分析发现性别二态性在不同的人群中有所不同,因此有必要获得特定人群的值,从而尽可能容易地识别人。本研究的目的是利用牙齿的线性尺寸和指数等参数来建立性别分化。选取年龄在17至24岁之间的100名受试者(男性50名,女性50名)的上颌模型。采用精密卡尺测量除第三磨牙外上颌铸型各牙的中远端(MD)和颊舌(BL)尺寸,计算牙指数。采用SPSS软件20进行数据收集和统计分析。在左中切牙、犬齿和左第一磨牙的情况下,颊舌尺寸是比MD更好的评价性别的参数。右侧中切牙、第二前磨牙和左侧第一磨牙的冠指数是大多数牙齿性别预测的最佳指标。

The periorbital soft-tissue characteristics provide an immense number of anatomical landmarks which could help in various forensic investigations. This work aimed to assess the forensic value of anthropometric measurements of periorbital soft tissue landmarks in sex discrimination. Two hundred Egyptian healthy young individuals of both sexes were included in the study. Their ages ranged from 18-40 years. The following anthropometric measures were estimated for all participants: inter-inner canthal width (IICD), inter-outer canthal width (IOCD), horizontal palpebral width (HPD), orbital height, upper and lower eyelids heights in addition to some computed orbital indices. A significant difference was found between males and females regarding the IICD, IOCD, HPD, palpebral fissure index and left orbital index. The current observations provide a database for adult periorbital anthropometry in Egyptians. Also, they could aid in personal identification and sex differentiation especially when combined with other facial characteristics. Further anthropometric studies on periorbital soft tissue landmarks are warranted using other modern techniques such as digital photography and software image analysis for documentation of antemortem data which could aid the process of forensic identification in civil and criminal medicolegal investigations.
眶周软组织的特征提供了大量的解剖标志,可以帮助各种法医调查。本研究旨在评估眶周软组织地标的人体测量在性别歧视中的法医价值。200名埃及男女健康的年轻个体参与了这项研究。他们的年龄从18岁到40岁不等。对所有参与者进行以下人体测量:内眦宽度(IICD)、外眦宽度(IOCD)、水平睑宽(HPD)、眼眶高度、上下眼睑高度以及一些计算的眼眶指数。在IICD、IOCD、HPD、睑裂指数、左眼眶指数方面,男女差异有统计学意义。目前的观察结果为埃及成人眶周人体测量提供了一个数据库。此外,它们还有助于个人识别和性别区分,尤其是在与其他面部特征结合使用时。进一步的人体测量学研究需要使用其他现代技术,如数字摄影和软件图像分析来记录死亡数据,这可以帮助民事和刑事法医调查中的法医鉴定过程。

Leigh syndrome (LS) is one of the most puzzling mitochondrial disorders, which is also known as subacute necrotizing encephalopathy. It has an incidence of 1 in 77,000 live births worldwide with poor prognosis. Currently, there is a poor understanding of the underlying pathophysiological mechanisms of the disease without any available effective treatment. Hence, the inevitability for developing suitable animal and cellular models needed for the development of successful new therapeutic modalities. In this short report, we blocked FOXRED1 gene with small interfering RNA (siRNA) using C57bl/6 mice. Results showed neurobehavioral changes in the injected mice along with parallel degeneration in corpus striatum and sparing of the substantianigra similar to what happen in Leigh syndrome cases. FOXRED1 blockage could serve as a new animal model for neuro-toxicological studies of Leigh syndrome due to defective mitochondrial complex I (CI), which echoes damage to corpus striatum and affection of the central dopaminergic system in this disease. Further preclinical studies are required to validate this model.
利氏综合征(LS)是最令人费解的线粒体疾病之一,也被称为亚急性坏死性脑病。全世界每7.7万活产婴儿中就有1例患有此病,预后不良。目前,由于缺乏有效的治疗方法,对该病的病理生理机制了解甚少。因此,开发合适的动物和细胞模型是开发成功的新治疗方式所必需的。在这篇简短的报道中,我们用小干扰RNA (siRNA)阻断了C57bl/6小鼠的FOXRED1基因。结果显示,注射小鼠的神经行为变化与Leigh综合征病例相似,纹状体平行变性和脑实质保留。FOXRED1阻断可作为线粒体复合物I (CI)缺陷引起的Leigh综合征神经毒理学研究的新动物模型,这与该病纹状体损伤和中枢多巴胺能系统的影响相呼应。需要进一步的临床前研究来验证该模型。

Carbon monoxide (CO) is known as a silent killer. In Egypt, it is one of the most common causes of death-related poisonings. This study aimed to evaluate some scoring systems; Glasgow coma scale (GCS), acute physiology and chronic health evaluation II (APACHE II), simplified acute physiology score II (SAPS II) and rapid emergency medicine score (REMS) for predicting in-hospital mortality of patients with acute CO poisoning. One hundred and eight acutely CO poisoned patients were included in the study. For each patient, socio-demographic and toxicological data were recorded. Clinical examination and calculation of the four scoring systems were performed. Patients were divided into two groups; survivors and non-survivors. Discrimination was evaluated using ROC curve and calculating the area under the curve (AUC). The current study revealed that median age of the studied patients was 25.5 years, 55.6% were males and 61.1% were from rural areas. All cases were intoxicated accidently. Among the studied 108 patients; 20 patients died in hospital and 88 patients survived. Both APACHE II and SAPS II had the best AUC, followed by REMS then GCS. The AUC of GCS was significantly lower than those of APACHE II, SAPS II and REMS scores; while differences between AUC of APACHE II, SAPS, and REMS were not statistically significant. It could be concluded that REMS is more useful in predicting in-hospital mortality in acute CO poisoning as it is a simple, easy and rapid scoring system rather than more complicated scoring systems such as APACHE II and SAPS II.
一氧化碳(CO)被称为无声杀手。在埃及,它是与死亡有关的中毒的最常见原因之一。本研究旨在评估一些评分系统;格拉斯哥昏迷量表(GCS)、急性生理和慢性健康评估II (APACHE II)、简化急性生理评分II (SAPS II)和快速急诊医学评分(REMS)预测急性一氧化碳中毒患者住院死亡率。108例急性一氧化碳中毒患者纳入研究。记录每位患者的社会人口学和毒理学数据。对四种评分体系进行临床检查和计算。患者分为两组;幸存者和非幸存者。采用ROC曲线和曲线下面积(AUC)评价辨别力。本组患者年龄中位数为25.5岁,男性占55.6%,农村占61.1%。所有病例均为意外中毒。在108例患者中;20名患者在医院死亡,88名患者存活。apache2和SAPS 2的AUC最高,REMS次之,GCS次之。GCS评分的AUC显著低于APACHE II、SAPS II和REMS评分;而APACHE II、SAPS和REMS的AUC差异无统计学意义。相对于APACHE II、SAPS II等较为复杂的评分系统,REMS评分系统简单、简便、快速,在预测急性CO中毒住院死亡率方面具有较好的应用价值。

Acetaminophen (APAP) is a commonly used analgesic-antipyretic drug. Overdose of APAP is significant global clinical problem in humans. Sitagliptin (Sitg) an anti-diabetic drug, has shown protective effects against organs toxicities. This work aimed to evaluate the protective effect of Sitg against APAP-induced hepatotoxicity. Forty male rats were divided into four equal groups. Group-I (control; C-GP; distilled water), Group-II (Sitg-GP; 20-mg/kg), Group-III (APAPGP; 500-mg/kg), and Group-IV (Sitg+APAP-GP; 20-mg/kg+500-mg/kg) pretreated with Sitg followed 2-hour later by APAP. The dosages were given once daily by gavage for 15 days and then blood and liver specimens were collected. Liver biomarkers were assayed in sera and included enzymes (aspartate transaminase=AST; alanine transaminase=ALT; alkaline phosphatase=ALP; gamma-glutamyltransferase=GGT; lactate dehydrogenase=LDH), bilirubin (total bilirubin=TB; direct bilirubin=DB; indirect bilirubin=IB), and proteins (total protein=TP; albumin=ALB; globulin=GLB). Oxidative stress biomarkers were estimated in homogenates and included antioxidants (superoxide dismutase=SOD; catalase=CAT; glutathione peroxidase=GPx; glutathione-S-transferase=GST; glutathione=GSH) and oxidative malondialdehyde (MDA) besides tissue total redox status (total oxidative status=TOS; total antioxidant capacity=TAC; oxidative stress index=OSI; OSI=TOS/TAC). The hepatic lesions were semi-quantitatively scored. In APAP-GP, concentrations of all enzymes and bilirubin, MDA, TOS, and OSI were significantly increased, while levels of all proteins, antioxidants, and TAC were significantly decreased. Histopathological changes showed distorted architecture, increased fibrous deposition, and reduced glycogen contents. Pretreatment with Sitg markedly prevented APAP-induced biochemical and histopathological abnormalities. Sitg possess remarkable hepatoprotective effects against APAPinduced hepatotoxicity and may be useful in treatment of APAP-poisoned patients with diabetes mellitus.
对乙酰氨基酚(APAP)是一种常用的镇痛解热药物。APAP用药过量是人类重大的临床问题。西格列汀(Sitagliptin, Sitg)是一种抗糖尿病药物,对器官毒性具有保护作用。本工作旨在评价Sitg对apap诱导的肝毒性的保护作用。40只雄性大鼠被分成四组。第一组(控制;C-GP;蒸馏水),ii组(Sitg-GP;20 mg/kg), iii组(APAPGP;500 mg/kg)和iv组(Sitg+APAP-GP;20 mg/kg+500 mg/kg), Sitg预处理,2小时后APAP。每天1次灌胃,连续灌胃15 d,然后采集血液和肝脏标本。检测血清中的肝脏生物标志物,包括酶(天冬氨酸转氨酶=AST;丙氨酸氨基转移酶(ALT;碱性磷酸酶=高山;gamma-glutamyltransferase = GGT;乳酸脱氢酶=LDH)、胆红素(总胆红素=TB;直接胆红素=数据库;间接胆红素=IB)和蛋白质(总蛋白=TP;白蛋白=铝青铜;球蛋白= GLB)。在匀浆中估计氧化应激生物标志物,包括抗氧化剂(超氧化物歧化酶=SOD;过氧化氢酶=猫;谷胱甘肽过氧化物酶(GPx);glutathione-S-transferase =销售税;除了组织总氧化还原状态(total oxidation status=TOS;总抗氧化能力=TAC;氧化应激指数=OSI;OSI =服务条款/ TAC)。对肝脏病变进行半定量评分。在APAP-GP中,所有酶和胆红素、MDA、TOS和OSI的浓度均显著升高,而所有蛋白质、抗氧化剂和TAC的水平均显著降低。组织病理学改变显示结构扭曲,纤维沉积增加,糖原含量降低。Sitg预处理可显著预防apap诱导的生化和组织病理学异常。Sitg对apap诱导的肝毒性具有显著的肝保护作用,可用于治疗apap中毒的糖尿病患者。

Increased rate of seizures and respiratory complications due to tramadol poisoning have been observed, even with first time of tramadol intake. So, the present work was used to investigate the clinical manifestations and laboratory investigations of acute tramadol toxicity and the correlation between toxic tramadol manifestations and blood tramadol level and laboratory parameters. A study was performed on 100 patients (80 males and 20 females) acutely intoxicated with tramadol, admitted to toxicology unit of Al-Azhar University Hospital (New Damietta) in the period from January to December 2017. Informed consent, urine sample was collected and 10 mL of blood was separated and used for extraction of tramadol residues by using a high-performance liquid chromatography (HPLC) and other blood samples were stored at-8°C for routine investigations. Then a detailed clinical examination was done to all patients. Generally, the frequency of seizures was (46 %) with acute tramadol poisoning. There was no correlation between blood tramadol level and toxic manifestations of tramadol poisoning. So, the frequency of seizures and toxic manifestations are not dosed dependent. Cannabis was the most common co-ingested drugs and adult males were more commonly affected by tramadol poisoning. It is recommended that the drug abuse problem must be treated at the level of community problems in order to minimize medical emergencies related to acute tramadol overdose occurring mostly by addiction and further studies should be proposed to extend our knowledge about relationships between sex and seizures among tramadol intoxicated patients
已观察到曲马多中毒引起的癫痫发作率和呼吸系统并发症增加,即使是第一次摄入曲马多。因此,本工作旨在探讨急性曲马多毒性的临床表现和实验室调查,以及毒性曲马多表现与血曲马多水平和实验室参数的关系。对2017年1月至12月在爱资哈尔大学医院(New Damietta)毒理学部住院的100例急性曲马多中毒患者(男80例,女20例)进行了研究。知情同意后,采集尿样,分离10ml血液,采用高效液相色谱法提取曲马多残留,其他血样在8°C下保存,用于常规检查。然后对所有患者进行详细的临床检查。一般来说,急性曲马多中毒患者癫痫发作的频率为46%。曲马多血药浓度与曲马多中毒的毒性表现无相关性。所以,癫痫发作的频率和中毒症状不依赖于剂量。大麻是最常见的共摄入药物,成年男性更常受到曲马多中毒的影响。建议药物滥用问题必须在社区问题层面进行治疗,以尽量减少主要由成瘾引起的急性曲马多过量相关的医疗紧急情况,并应提出进一步的研究,以扩大我们对曲马多中毒患者中性与癫痫发作之间关系的了解
