Acquired Complete Heart Block with Long QT Interval and Recurrent Polymorphic Ventricular Tachycardia: A Case Report  [PDF]
Hosam Zaky, Jassem Al Hashmi
Open Journal of Internal Medicine (OJIM) , 2016, DOI: 10.4236/ojim.2016.62008
Abstract: We are reporting a case of acquired complete heart block and long QT interval (a dispersion of repolarization that leads to polymorphic ventricular tachycardia) that has presented with loss of conscious and proved to be due to torsade de pointes. The patient responded well to cardiac pacing and beta blocker therapy. The association of complete acquired heart block and long QT interval is quite rare.

Location Privacy and Energy Preservation in Sensor Allocation Systems
Hosam Rowaihy
International Journal of Distributed Sensor Networks , 2012, DOI: 10.1155/2012/197592
Abstract: We propose sensor-to-task assignments algorithms that take into account location privacy issues. Our solutions enable the network to choose the “best” assignment of the available sensors to the tasks to maximize the utility of the network while preserving sensors’ location privacy. We focus on preserving the sensors’ locations during the assignment process in contrast to previous works, which considered location privacy while sensors are in operation. We also propose an energy-based algorithm that uses the remaining energy of a sensor as a factor to scale the distance between a sensor and a task such that sensors that have more energy appear to be closer than ones with less energy left. This does not only provide location privacy but will also consume the sensing resources more evenly, which leads to extending the lifetime of the network. From our simulations, we found that our algorithms can successfully hide sensors’ locations while providing performance close to the algorithms, which use the exact locations. In addition, our energy-based algorithm, while achieving results close to the exact location algorithm, was found to increase the network lifetime by as much as 40%.
Assessment of the Nutritional Status of the Egyptian Patient with End Stage Liver Disease Prior to Liver Transplantation  [PDF]
Waheed A. Monsef, Ibrahim Mostafa, Doaa Zaky
Open Journal of Gastroenterology (OJGas) , 2014, DOI: 10.4236/ojgas.2014.44024
Abstract: Background and Aim: Patients with advanced liver disease have several risk factors to develop nutritional deficiencies. Accurate nutritional assessment is a real challenge because many of the traditionally measured parameters of nutritional status vary with severity of liver disease independently of nutritional status. The objective of this study was to assess the Egyptian patients with end stage liver disease and to compare different tools used to assess their nutritional status. Patients and Methods: 60 patients were nutritionally assessed by SGA, RFH-SGA anthropometry, handgrip dynamometry and biochemical tests. Clinical variables were cross analyzed with the nutritional assessment methods. Results: Malnutrition ranged from 7% by BMI and 100% by SGA. Agreement among all the methods was low compared with the SGA. Correlation between Malnutrition prevalence and the severity of liver disease was verified using Child-Pugh score more than MELD score. Conclusion: Malnutrition is highly prevalent among the Egyptian patients with end stage liver disease prior to liver transplantation. Although the diagnosis of nutritional status is not easy among this category of patients, it varied according to the method used. Nutritional support should be an important part of the preoperative care of liver transplantation patients.
Screening of Bacterial and Fungal Biota Associated with Oreochromis niloticus in Lake Manzala and Its Impact on Human Health  [PDF]
Mahmoud M. M. Zaky, Mohsen E. Ibrahim
Health (Health) , 2017, DOI: 10.4236/health.2017.94050
Abstract:
In this study fish samples were investigated for Bacteria and Fungi, in fish parts, such as intestine, gills and skin. Bacterial counts of Total viable bacteria (T.V.B) reached more than 9.5 × 105 cfu and faecal coliforms (F.C) reached 1.2 × 105 cfu. Different species were identified, Using API technology. Escherichia coli comes first by being recording thirty number case of isolation constituting 36%, it followed by Proteus mirabilis which is represented by twenty four number case of isolation accounting for 30%. Other taxa viz: Klebsiella pneumonia, Citrobacter freundii, Providencia stuartii and Erwinia sp. came next according to their case number of isolation, they represented only by 7%. They showed different antibiotics with different inhibitory concentrations, resistance pattern to gentamycin 10 μg, Penicillin G, tetracycline 30 μg, Ampicillin 10 μg, Ampicillin 30 μg, chloramphenicol (C) 30 μg, Rifampicin 25 μg, Streptomycin 5 μg, cefotaxime 15 μg. Mycological investigation revealed the presence of variety of fungal species, particularly, toxigenic species, such as, Aspergillus spp, Penicillium spp and Fusarium spp. These results are indication of the spoilage of fishes which caught from Lake Manzala and are risky for human consumption and hazardous to human health in this important area of Egypt, due to the high pollution condition of Lake Manzala.
Percutaneous dilational tracheostomy in critically ill patients: progressive vs single dilatation techniques
S Zaky, K Atya
Critical Care , 2004, DOI: 10.1186/cc2470
Abstract: Prospective observational study.Eighteen surgical or medical ICU patients (10 male, mean age 32.8 ± 17 years) in a tertiary university hospital requiring tracheostomy for airway control or prolonged mechanical ventilation.Patients were randomized to receive PDT by either the multiple progressive dilatation method (group A, eight patients) or single dilatation technique (group B, 10 patients) as described by Ciaglia.Bedside PDT was performed successfully in ICU for all 18 patients in a mean time of 17.5 ± 14 min (range 5–60 min). Single dilatation technique had a significantly lower operative time than the multiple dilation group (9.5 ± 6 min vs 27.5 ± 15 min, P < 0.005). Complications were significantly higher in group A (false passage in one, moderate bleeding in one, minor bleeding in two, conversion of the procedure to open tracheostomy in one patient due to isthmus bleeding). On the other hand there was only minor bleeding in one patient of group B.PDT is a safe and cost-effective procedure in ICU critically ill patients. The single dilatation method is an even more rapidly performed bedside method than the progressive dilation method.
Gunpowder and Arab Firearms in Middle Ages
Rahman Zaky, A.
Gladius , 1967, DOI: 10.3989/gladius.1967.186
Abstract: THERE is no certainty as to the actual date of the invention of gunpowder. The evidence that the Chinese possessed it in ancient times is not conclusive. Among the claimants of discovering gunpowder are Chinese, Indians, Greeks, Arabs, English and Germans. Who first thought of propelling a ball through a metal tube by exploding gunpowder is unknown; anyhow; it certainly was not Monk Berthold Schwartz. Consultar resumen en inglés.
A Preliminary Bibliography of Medieval Arabic Military Literature
Rahman Zaky, A.
Gladius , 1965, DOI: 10.3989/gladius.1965.191
Abstract: BEFORE Islam, the Arabs of the Peninsula had their own local system of warfare, that was not of big armies, but of small battles and skirmishes among the tribes. After the death of Muhammad (632), the caliphs established their rule in Arabia, and started their conquests towards Iraq and Persia in the East; and towards Syria, Egypt and North Africa in the West. After the conquest of Spain (711), the Arabs had already built a vast empire extending from the Atlantic shores to the Indus in about one hundred years. While the Arabs began to develop their warfare system, they did not disdain to learn many lessons from the nations they already defeated. Accordingly the Byzantine army served as a model for their land forces. Arab writers and translators began to contribute invaluable treatises on war, archery and chivalry. It is a pity that very few of these have survived, whether Arabic or Persian. Some of the treatises were the translations of books written in Latin, Greek, Persian or Sanskrit. One can say that by the tenth century, the Arabs had an art of war of their own. No disponible
