الشروط العمرية في الأدبيات الإسلامية والسريانية ووثائق جنيزة القاهرة
Authors: الخالدي فاطمة
Published: October 2022

تسعى هذه الدراسة إلى الكشف عن الإشكاليات التي تعاني منها نصوص ”الشروط العمرية“، والتي تحول دون اتخاذها أصلاً تؤسس عليه الأحكام الشرعية الخاصة بأهل الذمة. وأهمية الدراسة تنبع من خطورة موضوع هذه الشروط، فهي -إن صحت- تعتبر دستوراً يحكم علاقة الدولة الإسلامية برعاياها من غير المسلمين. وخلصت الدراسة إلى أن انتشار نسخ عديدة لهذا العهد لا يحول دون ردها نظراً لما يعتريها من اضطراب شديد في المتون، وعلل في الأسانيد، بالتزامن مع الواقع التاريخي الذي يبين أن هذه الشروط لم يجر تطبيقها إلا نادراً، وهو أمر أكدته عدة مصادر مثل الوثائق السريانية الخاصة بنصارى الشام والعراق، ومجموعة وثائق جنيزة القاهرة العائدة إلى الطائفة اليهودية في مصر. كما كشفت الدراسة أنه لا يمكن غض الطرف عن أثر الأخطار التي شهدها العالم الإسلامي على يد المغول والصلبيين في اختلال علاقة المسلمين بغيرهم كأحد العوامل الرئيسة وراء انتشار نسخ هذا العهد في المصادر الإسلامية، إضافة إلى غياب الفهم الشمولي لفكرة المجتمع الإسلامي.
التظلم الإداري غير القضائي ( دراسة مقارنة بالفقه الإسلامي )
Authors: علي عبدالإله
Published: October 2022

تصدر الإدارة قرارات شتى، بحق الموظفين وغيرهم، وقد تؤثر هذه القرارات على الوضع المالي والإداري للموظف، لا سيما إذا كانت قرارات تأديب، فيحق للموظف إنْ رأى عدم مشروعية القرار أن يطعن به قبل اللجوء للقضاء.

فالتظلم هو لجوء صاحب الشأن إلى الإدارة شاكيا من قرار إداري، يظن أنه معيب، ويرمي إلى إلغائه أو سحبه أو تعديله.

    وفي القوانين الوضعية، فقد عرفت التشريعات مناط الدراسة، التظلم وأنواعه، وشروطه ونتائجه، ومن له حق اللجوء إليه، وما هي الجهة التي يرفع التظلم لديها، والاثار المترتبة على تقديمه.

وبالرجوع إلى الفقه الإسلامي، فقد عرف ولاية المظالم منذ عهد الرسول محمد -صلى الله عليه وسلم-، مرورا بعهد الخلفاء الراشدين ومن تبعهم، وبينوا قضاء المظالم من حيث السلطة والمكان والشروط المتعلقة به، سواء من قبل المتظلم، أو ناظر المظالم.

Published: October 2022

The study explored how the interactive attributes of new media technologies influence thegratification-seeking behaviour of millennials. Using a mixed methods approach, it employed asurvey and focus group interviews to collect data from university students. From a population of2 400 university students from the Political Science Department of a renowned public universityin Ghana, 400 students were systematically sampled for the survey, while 40 students werepurposively selected for focus group discussions. The findings indicate that the interactive featuresof the technologies produced emerging social and psychological gratifications in millennialsby projecting them as purposeful, and active in deploying symmetric political communicationrepertoires. The practical implication of this is that political leaders need to invigorate their electoralcommunication repertoires both in substance and in depth by deploying the heuristic attributes ofthe new technologies to facilitate the awakening of visceral responses in millennials and get themto engage in e-politics.
Revenge pornography on the internet
Authors: Wanjiku Evelyne
Published: October 2022

Revenge pornography, which is mainly understood as the publication of nude or intimate picturesof another person without their consent, is a phenomenon that is increasing in occurrence andconstantly changing in the manner in which it is carried out. In Kenya, due to the absence of aproper regulatory mechanism, perpetrators continue to carry out their activities with resoundingimpact and devastating effects on the victims. This article uses discourse analysis to explore themotivations behind non-consensual pornography, reasons and motivations for its prevalence,which include revenge and punishment, entertainment/fun, the sexual objectification of women,“slut shaming”, and denigration of the victim’s character. The paper also looks at the legal andgendered aspects that allow the vice to continue being perpetrated. These include the lack ofclearly defined laws that capture the various forms that revenge pornography can take and thelack of well-trained legal officers and law enforcers who can handle reported cases of revengepornography. The article argues in favour of reform of the current legal framework in order toaddress non-consensual pornography as mediated by the tools of digital technology. This includesa clear legal definition of revenge pornography.

Published: October 2022

Blockchain is the key concept for security purposes for digital applications. But, in some cases, the effectiveness of the malicious behavior has degraded the security function of the blockchain. So, to enrich the blockchain process prediction and to neglect the malicious event from the data broadcasting medium is very important. So, the current research article intends to develop an efficient monitoring strategy based on incorporating deep features. Hence, the designed paradigm is termed as Lion-based Convolutional Neural Model (LbCNM) with serpent encryption. Before performing the encryption process, the novel LbCNM parameters have been activated to monitor the data process channel in the blockchain environment. Here, the malicious behaviors were estimated by incorporating the known and unknown user behavior in the Lion fitness model. During the execution, the fitness formulation of Lion is acted in the classification layer of the convolutional model. Once the present malicious characteristics have been detected, it is neglected from the data broadcasting channel. Hereafter, the transactional data has been encrypted and stored in the specific cloud. The planned strategy is verified in the python platform. The successful performance of the LbCNM with serpent has been analyzed with some key parameters like confidential rate, accuracy, data overhead, and processing time.

Cavernomas are frequent low-flow vascular malformations with a characteristic MRI aspect due to their specific morphology. We present the case of a 64-year old male diagnosed in 2008 with multiple cerebral cavernomas and symptomatic epilepsy, who developed left face, arm and leg paresthesia during the last 6 days. The MRI examination performed in our clinic showed increased number of infracentimetic lesions with no signs of hemorrhage or growth of the previous documented ones. Considering MRI findings and the patient being seizure free for the last three years there is no current indication for invasive treatment. The presence of multiple lesions along with their aspect on T2* MRI sequences suggest a hereditary form in absence of familial history of cerebral cavernous malformations.

We are presenting the case of a 43 year old man, without significant pathological antecedents, who accused back pain with irradiation on the back of the thigh and the right calf, which were associated with paresthesia at the same level. Symptoms appeared a year ago, when the patient was on symptomatic treatments with minimal results. On the generally examination there are found fifteen café au lait spots, distributed on the torso and limbs with the diameter above 15 mm, axillary hyperpigmentation, ten cutaneous neurofibromas with the same distribution and Lisch nodules in the iris. We proceeded to MRI examination of the lumbar spine that reveals an important irregular thickening, tortue with pseudotumor aspect, predominantly in the extraforaminal and peripheric path and less in the intraforaminal of nerve roots from T12 to the sacral roots; widening of the conjugation foramina; changes are more pronounced in the sacral plexus (left > right), the terminal segments presenting the appearance of „pelvic mass“ – MRI compatible with plexiform neurofibromas aspect. The final step was the histopathological examination which confirmed the diagnostic. The particularity of this case is that this patient was very late diagnosed, despite the fact that he had many pathognomonic elements of neurofibromatosis, and his symptomatology was rough, usually this disease is diagnosed in childhood or as an young adult.

The cerebral CT performed revealed a right massive chronic subdural hematoma which met the criteria for neurosurgical approach requiring a large craniotomy for complete removal. In this article we review the risk factors associated with an unpredictable evolution and postoperative subdural hematoma recurrence in the elderly.

Multiple sclerosis (MS) is a demyelinating disease associated with a myriad of visual pathways pathology. These pathologies need to be assessed, even when asymptomatic, because they may represent an important index of disease course, severity and treatment response. This is a review of the importance of different visual pathways assessment methods such as classic ophthalmologic examination, cerebrospinal fluid analysis, Doppler ultrasonography of the orbital vessels, magnetic resonance imaging, optical coherence tomography, visual evoked potential, evaluating which may contribute to elucidate the pathophysiological process, structural and functional damage. The modern medical technology developed multiple methods which are trying to link their results to the overall brain damage in MS. A global analysis of these methods is needed, in order to a better evaluation of visual pathways damage associated with multiple sclerosis.

Objectives. Septo-optic dysplasia (SOD), also known as de Morsier syndrome is a rare congenital syndrome involving variable midline brain structures, characterized by visual impairment, pituitary deficiencies and specific brain abnormalities (especially midbrain malformations). The clinical phenotype is highly variable, from mild to extremely severe. The purpose of this paper is to present the electroencephalographic abnormalities in two clinical cases and correlate with the ones that have been described in the literature in order to find a specific trait of this syndrome. Methods and results. A 12-year-old girl was hospitalized in the pediatric neurology clinic for focal seizures, developmental delay and cerebral palsy. Clinical examination showed visual disturbances (nystagmus and oculomotor nerve palsy), unilateral pyramidal syndrome – left hemiparesis. Electroencephalography (EEG) revealed bilateral photosensitive epileptic form discharges, but asymmetrical, right more than left, with abnormal, slower background. MRI showed optic nerve hypoplasia and hypoplasia of the corpus callosum. The second case was also a girl, a 7-year-old who had only 2 focal right motor seizures with secondary generalization and developmental delay. Clinical examination showed visual impairment and bilateral nystagmus. The standard EEG evaluation didn’t reveal any abnormalities, with normal background. Cerebral MRI showed midline brain defects – agenesis of the septum pellucidum, agenesis of corpus callosum and optic nerve hypoplasia. Endocrine evaluation for pituitary function showed in the first case – increased thyroid-stimulating hormone and in the second case – decreased IGF1. Antiepileptic treatment was started in both cases, but seizures were refractory to treatment and persistent EEG abnormalities still present in the first case, with good evolution of epilepsy in the second case. Conclusions. The epileptiform abnormalities associated to SOD are present only if there is an associated cortical malformation.

Deep brain stimulation is the most used neurosurgical procedure for advanced Parkinson’s disease. This procedure improves motor symptoms and some non-motor symptoms over a long period of time. In rare cases there are several complications which might lead to system removal. We report here a case were removal of the stimulation system was prompted by a scalp infection which extended to the subcutaneous fatty tissue and subcutaneous wire trajectories and did not resolved with antibiotics. The symptomatology worsened after device removal and reimplantation was decided. We followed this patient for 8 years after the first implant (6 years after the second implant) and he still has a good quality of live, being completely independent in most daily tasks.

In this article, we report an 18-year-old male patient with extrapulmonary paravertebral hydatid cysts with coexisting costovertebral tuberculosis. During the recent years the patient underwent multiple surgical interventions due to recurrent paravertebral abscess in the thoracic region, which resulted in mass effect at the spinal cord and palsy with urinary disorders. The cause of the abscess turned to be coexistent extrapulmonary tuberculosis and hydatid disease. This case emphasizes the importance of considering the coexistence of echinococcosis and tuberculosis in endemic areas.

Migraine is a common neurological disease characterized by severe, recurrent episodes of throbbing, unilateral, headache. Non-pharmacologic migraine treatment refers to the patient behavioral modification in order to avoid trigger. Current therapies in migraine attack treatment are non-specific drugs (non-steroidal anti-inflammatory drugs, aspirin, antiemetics) and specific antimigraine drugs (ergot alkaloids, serotonin 5-HT1B/1D receptor agonists – triptans). For migraine prophylaxis are recommended beta-blockers (metoprolol, propranolol), calcium channel blockers (flunarizine), antiepileptic drugs (valproic acid, topiramate), antidepressants (amitriptilyne, fluoxetine).

Alzheimer’s Disease (AD) is the most common form of dementia in the old population, carrying a major negative influence upon society and caregivers, as its socio-economic implications are enormous. The devastating impact of AD is also due to the fact that the diagnosis is difficult to be established in an early stage, and in spite of the advances made in medicine, the new symptomatic and disease modifying therapies have still only a mild though promising positive effect. Caregivers are exposed to increased risk of disease themselves, due to the high burden which predisposes them to stress related psychological, behavioral or cognitive disorders. Greater caregiver resilience can predict lower levels of depression. Also a strong external support system was associated with increased resilience. Establishing a pattern for the behavioral and psychological manifestations in dementia can have as direct effect developing better coping strategies in order to reduce stress and the burden of the caregivers. Some data regarding the economic and social impact of AD, as well as facts and numbers from our local centers will be described in the following pages.
