Abstract: RATIONALE: Crustaceans, such as shrimp, crab, crayfish and lobster, play important role in human nutrition; they also can be important causes of severe acute hypersensitivity reactions. For patients diagnosed with a crustacean allergy, strict avoidance is the only proven therapy, highlighting the need for more specific treatment. Our aim was to evaluate the efficacy and tolerance of sublingual shrimp immunotherapy in Egyptian patients allergic to shrimp. METHODS: This study was intended to help in diagnosis of shrimps allergen in 60 allergic patients (subdivided to 3 groups Urticaria (G1), rhinitis (G2) & asthma (G3)) and evaluate the sublingual immunotherapy by employing skin prick test, specific Immunoglobulin E, Total Immunoglobulin E, Immunoglobulin G, Eosinophilis and Peak Expiratory Flow Rate (PEFR), before and after therapy. Inclusion criteria were a history of shrimp allergy and positive skin prick test to crude shrimp extract from two species [Penaeus semisulcatus and Metapenaeus stebbingi] at allergy and clinical immunology unit, in-Shams Hospitals. They underwent immunotherapy with extract of shrimp species and administered sublingually (SLIT). The measurement of all latter investigations for shrimp allergen on the start and 6 months after immunotherapy, as compared to placebo control, were performed. Results: The clinical response and laboratory improvement of the patients was correlated with their decline in the eosinophils (p < 0.001), total Immunoglobulin E (p < 0.001) and specific Immunoglobulin E test (p < 0.001) and with their increased in PEFR (p < 0.001) and Immunoglobulin G (p < 0.001). This study suggests that the most desenstized responsed group was rhinitis group followed by Urticaria group. Also,The more effective season induce allergy in summer (48.3%) followed by springs (28.3%) and genatic predisposition of allergic diseases was highly accepted in patients had a family history (68%). In conclusion, sublingual immunotherapy for shrimp allergy was safe, simple, uncostly, well tolerated and efficacious, gave a good results especially in the treatment of patients with allergic rhinitis.

Obesity is becoming a global health care problem and an increasing number of obese female patients are getting pregnant. Aim of our study was to know the prevalence of obesity in nulliparous women and its impact on pregnancy as well as fetus. Patients and Methods: All nulliparous women with single pregnancy and gestational age of 37 weeks and above were included in the study. Primigradvida with multiple pregnancies, fetal abnormalities, and gestational age less than 37 weeks were excluded. Patients were divided into normal, overweight and obese group according to their prepragnancy body mass index (BMI). Results: Total 2243 nulliparous women were included in the study, majority (56.8%) of patients were in the normal BMI group and only 24.8% were obese. But a significantly higher number of obese nulliparous women were in the age group of 18 to 29 years (P < 0.05). Comorbidities were significantly higher in obese primigravida. The incidence of gestational diabetes and pregnancy induced hypertension was significantly higher (P < 0.05) in obese nulliparous women. Overweight and

Purpose: This work was to study the clinic-epidemiological characteristics of patients with locally advanced NCSLC and to analyze their prognostic factors and also the results of different treatment modalities for local control and their effect on overall survival (OAS). Materials and Methods: This is a retrospective study including 121 patients with primary locally advanced NSCLC diagnosed between 2001 and 2010 at the radiotherapy department , National Cancer Institute, Cairo University, Egypt. Results: The study showed significant correlation between the tumor size < 7 cm, old age > 60, moderately differentiated tumors G2 and treatment outcomes; better locoregional control and better survival rates. On the opposite side poorly differentiated tumors G3, tumor size > 7 cm had the worst locoregional control and survival rates. The study also showed significant statistical correlation between treatment modality, locoregional control and survival rates. Patients who were treated by either concommitent chemo-radiotherapy or sequential chemo-radiotherapy had better local control compared to other patients who were treated by radical radiotherapy, and they also had the best survival rates among all the other treatment groups. The average 6 months OAS rates for all studied patients were 60.3% while 12 months survival rates were 38.8%. The median OAS was 7 months. Conclusions: From the present study, we concluded that concomitant chemo-radiotherapy is the treatment of choice for locally advanced non small cell lung cancer; also we concluded that better performance status and higher hemoglobin levels have better treatment outcome in these cases.

Egyptian Journal of Hospital Medicine , 2009,
Abstract: Background: Active opening of the eustachian tube is accomplished by contraction of the paratubal muscles. Disturbance of any of the ET functions may contribute to the development of otitis media (OM) with effusion and other middle ear diseases. Sonotubometry seems to be the most "physiologic" method for assessment of ET function and has the advantage that it can be performed on ears with an intact tympanic membrane and without the use of a pressure chamber. The aim of this study was to compare the Eustachian tube function using sonotubometry in patients with combined airway disease associated with Eosinophilic otitis media with that having combined airway disease without otitis media. Patients and methods: This study was applied on 45 patients divided into 3 groups each of 15. 1st group is the control group, 2nd group patients with combined airway disease without Eosinophilic otitis media, 3rd group patients with combined airway disease associated with Eosinophilic otitis media. Results: Our results explains that the tubal opening durations were significantly longer in patients of EOM group than in patients with combined airway disease without EOM group and also the normal control group.Conclusion: Sonotubometry can be performed in patients with or without an intact tympanic membrane and under physiological conditions. Sonotubometry is also inexpensive, painless, and easy to perform in both adults and children. Therefore, it has great potential value as a diagnostic tool for individuals with suspected ET disease

Abstract: Objective. We evaluated whether the methylenetetrahydrofolate reductase (MTHFR) 677C>T marker influences the risk and severity of Alzheimer's disease (AD) and whether AD is associated with homocysteine, vitamin B12, and cholesterol levels in Egypt. Methods. Forty-three Alzheimer's cases and 32 non-AD controls were genotyped for the 677C>T polymorphism. Clinical characteristics and levels of homocysteine, vitamin B12, and cholesterol were assessed. Results. No significant differences in the frequencies of the MTHFR alleles or genotypes between AD cases and controls ( ) were identified. The 677T mutant allele was significantly overrepresented in AD cases compared to controls ( ; ). The 677T/T frequency was three times higher in AD patients than in controls, which could increase plasma homocysteine levels. Severe cases of AD were the most frequent in patients with the T/T genotype (11.6%). The effect of the MTHFR polymorphism on the risk of AD may be independent of homocysteine, vitamin B12, or even cholesterol levels. Conclusions. The MTHFR 677C>T polymorphism—especially the presence of one copy of the T allele—appears to confer a potential risk for the development of AD. The T/T genotype may contribute to hypercysteinemia as a sensitive marker. 1. Introduction Alzheimer’s disease (AD, MIM 104300) is a major cause of disability in the elderly population. It is the most common form of dementia, affecting 1 in 8 individuals older than 60 years of age [1]. Most AD cases are late in onset and are probably influenced by both genetic and environmental factors. Clinically, AD generally begins with subtle short-term memory problems and then progresses to difficulties in memory, language, and orientation. In the late stage of AD, ventricular enlargement and shrinkage of the brain may be observed by magnetic resonance imaging. Some characteristic changes in the AD brain include neuronal loss in selected regions; intracellular neurofibrillary tangles in the neurons of the cerebral cortex and hippocampus; and neuritic plaques containing amyloids that may be further surrounded by dystrophic neurites, reactive astrocytes, and microglia [1]. Alzheimer Disease International estimates that there are currently 30 million cases of dementia in the world, with 4.6 million new cases occurring annually [2]. Statistics is much more ambiguous in the developing world, where few studies have examined the prevalence of dementia and where estimates vary widely. Evidence on the prevalence of AD is abundant in Europe and North America, patchy in South and Southeast Asia, and very

Patients and Methods: 30 patients divided into 3 groups (10 patients had medial sphenoid wing meningioma constituted group 1, 10 patients had suprasellar meningioma constituted group 2 and 10 patients had Cerbello-Pontine Angle (CPA) epidermoids constituted group 3) were operated through Endoscope Assisted Microscopic Skull Base Surgery technique at Al-Azhar University Hospitals during the period starting from January 2016 till the end of September 2017

Studies of Tectonic Motion from Helwan-Satellite Laser Ranging Station  [PDF]
Gamal F. Attia
International Journal of Astronomy and Astrophysics (IJAA) , 2014, DOI: 10.4236/ijaa.2014.44055
Abstract: Satellite Laser Ranging (SLR) is a proven space geodetic technique with significant potential for important contributions to scientific studies of tectonic motion. Currently, SLR is the most accurate available technique to determine the geocentric position with a reported precision in the order of few millimeters. Data gathered through SLR together with “Short Arc” mathematical algorithm became a highly precise tool to detect, monitor and calculate recent crustal movements through repeated measurements of the baselines between some stations on different tectonic plates. In this paper, the Short Arc mathematical model introduced in a previous paper was used to calculate the length of the baseline between Helwan-SLR station and other four fixed SLR stations, placed on different plates. Application of this model with the data gathered through a 4 year time interval gave repeatable results with very high accuracy (in the order of 4 cm).

Berseem clover (Trifolium alexandrinum L.) is the main winter forage legume in Egypt. Despite that the yield and protein content of berseem clover are high, it is characterized by low dry matter content especially in the 1st cut. Intercropping berseem clover with forage grasses, especially annual ryegrass (Lolium multiflorum Lam.) is a recommended technique to produce higher forage yield with better balanced nutritional quality. However, little is known about the performance of these proposed mixtures under the arising organic farming system in Egypt. Organic farming and the application of organic fertilizers (compost and poultry manure) are receiving increased attention in the last few years. Thus, the current study was carried out on the winter season of two successive years (2012 and 2013) in the experimental station of SEKEM organic farm, Egypt. Main aim was to investigate the variation in 1st cut forage yield and nutritive value of berseem clover and annual ryegrass, grown in pure stands and with three mixing rates, under three organic fertilization regimes (compost, poultry litter, and no fertilization). Nutritive value was judged through investigating the crude protein (CP), total carbohydrates (TC), and fiber fractions (NDF, ADF, and ADL). Results revealed significant two-way interaction between the forage treatments and the fertilization regimes for all the studied parameters. In general, mixing berseem clover with annual ryegrass, fertilized by compost or poultry litter resulted in significantly higher forage yield, dry matter content, and balanced CP, TC, and fiber fractions, compared to the pure stands.
