Trauma is a wound or injury caused by mechanical or physical factors. Trauma is a medical case with legal implications. Revolution of Egypt in the 25th of January 2011 was accompanied by dramatic changes in the Egyptian community attitudes that certainly had legal implications. Aim of the study: was to assess the changes in the medico-legal pattern of hospitalized trauma cases with evaluation of the homicidal cases concerning the cause and the final outcome especially in the post-revolution period. Participants and Methods: This study was a retrospective one that included 1527 hospitalized trauma cases who were collected from Trauma Unit of Assiut University Hospital in the period between January 2010 and December 2016. All the needed data was collected from health information system database of the Trauma Unit after taking the official consent from the unit director. The collected data included basic demographic data, cause of injury, mechanisms, mode and outcomes of trauma in all hospitalized cases. Results: 1527 hospitalized trauma cases were collected; mean age was 25.39 ± 15.4 years, male: female ratio was (6.6:1). The annual number of trauma cases was almost equal in the first 5 years then decreased gradually after that. Homicidal mode (assault from others) was approximately doubled from 22.6% in 2010 (before revolution) to 40.5% in 2011 and 38.0% in 2012 (after revolution), then decreased gradually in 2014 till 2016, also firearm injuries increased from 9.6% before revolution (2010) to 14.3% in 2011 and jumped to 31.0% in 2012 and 37.3% in 2013 then, decreased gradually after that. The accidental mode road traffic accident decreased from 40% before revolution to 26% and 20% in 2011 and 2012 respectively (after revolution). Conclusions: January 25th Egyptian revolution clearly changed the medico-legal pattern of trauma; from accidental pattern (road traffic accidents & falls) before revolution to homicidal pattern (assault from others & firearm injuries) in the post revolution period.

Background and aim Scorpion envenomation is a common acute life threatening health problem in developing countries as Egypt. Scorpion venom is a complex structure composed of neurotoxic proteins, salts, acidic proteins, and organic compounds, thereby having of neurologic, cardiovascular, hematologic, and renal side effects, in addition to local effects such as redness, pain, burning, and swelling. Aims The study consisted of two parts to describe demographic characteristics, toxicological manifestations of scorpion sting cases in Luxor, Egypt and morphological characterization of the commonest scorpion species in the studied community for easy rapid identification of scorpion species by doctors from the patient history to provide better choices of management Materials & methods First part of the study include all cases of scorpion envenomation attending General Hospital of Esna, Luxor, Egypt during the period of scorpion activity 2017, demographic data was collected then cases were assessed for clinical manifestations, ECG, complications and deaths related to scorpion species. Second part: scorpions were collected from areas around patient housing for morphological description of their sense organs and venom apparatus by Scanning Electron Microscopy. Results A total of 110 cases of scorpion stings were reviewed, males 81 (72.9%) and females 30 (27.1%), with a mean age of 31.9 ± 17.9 years. Localized pain was the most frequent presenting complaint (89 80.2%), vomiting was the commonest clinical symptom (90.9%). All scorpion stings were due to the most endemic species in North Africa, Leiurusquinquestriatus & Androctonuscrassicauda. Death rate among cases was (5.5%) all were Abroug’s Grade III. Cardiac dysrhythmia and subsequent pulmonary edema were the commonest cause of death. Clinical manifestations were more sever in Leiurus quinquestriatus stings while death rate was more in Androctonus crassicauda stings. The morphological characterization of the sense organs (eyes, pedipalps, pectines& sensory setae) and venom apparatus of the scorpions L. quinquestriatus & A. crassicauda were described by Scanning Electron Microscopy. Conclusion Scorpion sting is an acute heath threating in Southern Egypt, Leiurus quinquestriatus & Androctonus crassicauda are most endemic scorpion species in Southern Egypt. More attention for scorpion envenomation in such subtropical hyper desert localities is required to eradicate toxic scorpion species and prevent possible causes of deaths.

Hepatitis E virus (HEV) infection is endemic in developing and developed countries. HEV was reported to be excreted in the milk of ruminants, raising the possibility of transmission of HEV infection through the ingestion of contaminated milk. Therefore, the detection of HEV markers in milk samples becomes pivotal. However, milk includes inhibitory components that affect HEV detection assays. Previously it was reported that dilution of milk matrix improves the performance of HEV molecular assay, however, the dilution of milk samples is not the best strategy especially when the contaminated milk sample has a low HEV load. Therefore, the objective of this study is to compare the effect of extraction procedures on the efficiency of HEV RNA detection in undiluted milk samples. In addition, we assessed the effect of the removal of milk components such as fats and casein on the performance of the molecular and serological assays of HEV. Phosphate buffered saline (PBS) and different milk matrices (such as whole milk, skim milk, and milk serum) were inoculated with different HEV inoculums and subjected to two different extraction procedures. Method A includes manual extraction using spin column-based extraction, while method B includes silica-based automated extraction. Method A was more sensitive than method B in the whole milk and skim milk matrices with a LoD95% of 300 IU/mL, and virus recovery yield of 47%. While the sensitivity and performance of method B were significantly improved using the milk serum matrix, with LoD95% of 96 IU/mL. Interestingly, retesting HEV positive milk samples using the high sensitivity assay based on method B extraction and milk serum matrix increased the HEV RNA detection rate to 2-fold. Additionally, the performance of HEV serological assays such as anti-HEV IgG and HEV Ag in the milk samples was improved after the removal of the fat globules from the milk matrix. In conclusion, HEV RNA assay is affected by the components of milk and the extraction procedure. Removal of inhibitory substances, such as fat and casein from the milk sample increased the performance of HEV molecular and serological assays which will be suitable for the low load HEV milk with no further dilutions.
