Background and Purpose: Carotid atherosclerosis has been recognized as a major cause of stroke. The cur-rent study aimed to describe the effect of multiplicity rather than the type of vascular risk factors on severity of carotid atherosclerosis among a large sample of Egyptian population. Methods: We analyzed the data of 1969 Egyptian subjects, who proved to have extra cranial carotid atherosclerotic disease by duplex scanning at the vascular laboratories of Cairo Uni-versity Hospitals. Demographic, clinical data and causes of referral were recorded and correlated with ultrasound findings. Atherosclerotic indices, namely IMT, plaque number and percentage of stenosis were used for evaluation of severity of carotid atherosclerosis. Furthermore, subjects were classified according to multiplicity of major atherosclerotic risk factors and multivariate regression analysis was performed to detect independent predictors of significant carotid disease. Results: Out of 1969 subjects with proved signs of extracranial carotid atherosclerosis by duplex ultrasonographic scan, 225 (11.4%) showed hemody-namic significant stenosis (≥50%). Multiplicity of risk factors beyond the age of 50 years was the strongest predictor of significant stenosis. Conclusion: Age more than 50 years and multiplicity rather than the type of risk factors were the strongest predictors of significant carotid atherosclerotic disease (CAD).

A phenomenon known as trapped penis has numerous origins, including injudicious circumcision. Materials and Methods: Surgery for trapped penis with glanular amputation was performed for 5 children. The surgical policy in these cases included complete penile degloving, excising the scarring due to circumcission, fixing the penile skin at the penopubic and penoscrotal angles and reconstructing the penile skin with full thickness skin graft. Results: Improvement was noted in all cases. Conclusion: Surgery for hidden penis using full thickness skin graft achieves very satisfactory aesthetic and functional improvement.

The Golden Jackal (Canis aureus Linnaeus, 1758), which belongs to the Canidae family, is an opportunist carnivore in the Gaza Strip (365 square kilometers). The current study aims at giving notes on the occurrence and some ecological aspects of the species in the Gaza Strip, Palestine. The study, which lasted 14 years (2007-2020), is descriptive and cumulative in its style. It was based on frequent field visits, direct observations and meetings and discussions with wildlife hunters, farmers and other stakeholders. The findings of the study show that Gazans are familiar with the Golden Jackal to the extent that a Gazan family holds the Arabic name of the animal, which is “Wawi”. The Golden Jackal was sometimes encountered and hunted in the eastern parts of the Gaza Strip, which are characterized by the presence of wilderness areas, intensive agriculture, poultry pens and solid waste landfills. Like other a few mammalian faunas, the adult Golden Jackals enter the Gaza Strip through gaps in or burrows beneath the metal borders separating the Gaza Strip from the rest of the Palestinian Territories and Egypt. Gaza zoos were found to harbor tens of Golden Jackals trapped or hunted by clever wildlife hunters using different means such as wire cages known locally as “maltash” and foothold traps with metal jaws that may cause lesions to the trapped animals. Poisoning and shooting were also common methods used to control the jackals and other carnivores causing harm to agriculture and livestock. The animal was known among the Gazans as an omnivore, feeding on wild and domestic animals in addition to plant materials, garbage and carrions. In conclusion, the study recommends the need to raise ecological awareness to preserve the Golden jackal and to adopt safe control measures for jackals and other carnivores, including the construction of protective fences for agricultural fields and animal pens.

An environment friendly and cost effective factor of collapsible soilstabilization with the help of industrial waste has been widely adoptedin this research. Buildings which are constructed on collapsible soils aresubjected to large deformations and shear failure. Collapsible soil can bebroadly categorized as those soils susceptible to a large reduction in volumeupon wetting. The mechanism usually involved in rapid volume reductionentails breaking of bonds at coarse particle contacts by weakening of finegrainedmaterials brought there by surface tension in evaporating *** research presents the effects of using marble dust on the geotechnicalproperties of Collapsible soil as a new stabilizing technique. A series ofexperimental tests are carried for samples of collapsing soil with andwithout stabilization using marble dust for dry and soaked *** collapsible soil was mixed with marble dust at different contents of(0, 10, 20, 30%,40% and50%). The results indicated that, The optimumwater content decreases by 20.67% at marble content of 50%, liquidlimit decreses by35.41% at marble content of 50%and frictional angle forsoaked soil decreases by 66.09% at marble content of 50% while un soakedsoil decreases by54.68% at marble content of 50%. The maximum drydensity increases 5.91% at marble content of 50% and cohesion for soakedincreases314.2% at marble content of 50% while un soaked soil increases206.7% at marble content of 50%. It has been found that the adoptedmarble has a good effect in controlling the collapsing potential which isreduced by as much as 64.32% at marble content of 30%.

Background: Conventional hemodialysis (HD) used in treating end stage renal disease (ESRD) can result in multiorgan insult including the eye-owing to the resultant reperfusion after the ischemic event. Optimization of HD can be done using a process called remote ischemia which includes applying cycles of brief, nonlethal ischemia followed by reperfusion to one limb. This method sends signal to the end organs to prepare themselves for the upcoming ischemia thus preventing their injury. Aim: To evaluate the effect of remote ischemia preconditioning in HD on ophthalmological variables. Patients and Methods: A pre-post interventional analytical study conducted on patients receiving hemodialysis. Remote ischemia preconditioning was done before each HD session incorporating 3 cycles of alternating ischemia and reperfusion (5 minutes each) performed in the upper limb using sphygmomanometer cuff. Ophthalmic examination was done at baseline and 3 months after HD optimization. Assessment was done half to one hour pre- and post-session for visual acuity, corneal, conjunctival deposits, tear break up time (TBUT), anterior chamber depth and central macular thickness. Results: The study included 50 eyes of 25 patients with almost equal gender distribution and mean age of 37.52 ± 9.824 years. They were maintained on hemodialysis for median 10 years (range 3-25 years). The commonest cause of ESRD was hypertension. The studied ocular parameters showed insignificant change after pre-conditioned HD except for TBUT that was statistically longer (p = 0.018). Conclusion: Optimization of hemodialysis using remote ischemia does not seem to have significant ocular effect apart from prolonged TBUT. .
