Nosocomial Infections in a Morocco Burn Unit  [PDF]
Amine Rafik, Hakim Chabbak, Kawtare Jouhri, Mounia Diouri, Naima Bahechar, Abdes-samad Chlihi
Open Access Library Journal (OALib Journal) , 2015, DOI: 10.4236/oalib.1101394
Abstract: Introduction: The bacterial nosocomial infection remains a common cause of death in patients who have sustained a severe burn injury. Material and Methods: We conducted a prospective study of 45 patients hospitalized in the ICU burns Hospital IBN-ROCHD of Casablanca over a period of six months, from 1 January 2014 to 30 June 2014. The criteria for nosocomial infection were those of the Center for Disease Control in Atlanta in 1988. Result: Incidence rates were calculated. The bacterial ecology of the service was described as also antibiotype. The population was predominantly male (14 women and 31 men). Their average age was 39 years; the occurrence of 17 nosocomial infections in 45 patients appeared from this study. The cumulative incidence was 103 infections per 1000 days of treatment. Regarding the characteristics of bacterial infections, infected sites were skin (69%), blood (18%), urinary tract (12%) and lungs (1%). The main organisms were: Staphylococcus sp. (37.7%), Pseudomonas aeruginosa (19.8%), Enterococcus faecalis and Proteus mirabilis (18.5%). Staphylococci were méthicillin-resistant in 22% of cases. Pseudomonas and Acinetobacter were multi-resistant (66%). The establishment of the bacterial ecology of the service helped us set the right rules of prescription of antibiotics. Conclusion: Finally, controlling the epidemic risk posed by the emergence of resistant organisms is necessary to combine the practice of good antibiotic therapy and prevention.
Complete Fusion of the Maxillamandibular: Report of a Rare Case and Review of the Literature  [PDF]
Hakim Chabbak, Amine Rafik, Abdessamad Chlihi
International Journal of Otolaryngology and Head & Neck Surgery (IJOHNS) , 2015, DOI: 10.4236/ijohns.2015.43037
Abstract: The maxillomandibular fusion is a very rare condition, with no more than forty cases described in the literature. Adhesions of bone and/or soft tissue between the mandible and maxilla manifest themselves in the inability to open the mouth added to impacts on mandibular growth, nutrition and speech. This condition can be isolated or, when congenital, associated with other anomalies such as cleft lip and palate, aglossia, or Van der Woude syndrome. In the present paper, we report a case of maxillomandibular fusion treated in our department at University Hospital, between February 2011 and June 2014. The case is a congenital maxillomandibular fusion in a two-year-old infant, associated with a syndrome of Van der Woude. We discuss the diagnostic and treatment difficulties on the anaesthetic and surgical levels and the action to be taken to avoid recurrence. To date, some classifications have been suggested in the literature, but there is no standard treatment protocol. Early treatment is necessary to allow freedom of the upper airway, and ensure proper nutrition and good growth of facial bones. The success of surgery is conditioned by an adequate physiotherapy follow-up likely to guarantee the non-recurrence of the lesion.
An Agent-Based Framework for Automated Testing of Web-Based Systems  [PDF]
Samad Paydar, Mohsen Kahani
Journal of Software Engineering and Applications (JSEA) , 2011, DOI: 10.4236/jsea.2011.42010
Abstract: Parallel to the considerable growth in applications of web-based systems, there are increasing demands for methods and tools to assure their quality. Testing these systems, due to their inherent complexities and special characteristics, is complex, time-consuming and challenging. In this paper a novel multi-agent framework for automated testing of web-based systems is presented. The main design goals have been to develop an effective and flexible framework that supports different types of tests and utilize different sources of information about the system under test to automate the test process. A prototype of the proposed framework has been implemented and is used to perform some experiments. The results are promising and prove the overall design of the framework.
Thermal Performance of MEMS-Based Heat Exchanger with Micro-Encapsulated PCM Slurry  [PDF]
Samira Mehravar, Samad Sabbaghi
Journal of Power and Energy Engineering (JPEE) , 2014, DOI: 10.4236/jpee.2014.29003

Latent heat thermal energy storage technique has demonstrate to be a better engineering option mainly due to its benefit of supplying higher energy storage density in a smaller temperature difference between retrieval and storage. For this purpose, a micro electro-mechanical system, MEMS-based heat exchanger with microencapsulated PCM (MEPCM) slurry as cold fluid, has been simulated three dimensionally. This work investigates the influence of using MEPCM-slurry on the temperature of the cold and hot fluids. The MEPCM and water properties have been considered temperature dependent. MEPCM-slurry is used with different volume fractions. The result shows that using MEPCM with 25% volume fraction leads to the improvement in fluids temperatures, that is, for hot fluid the rate of temperature reduction increases up to 23.5% and for cold fluid the rate of temperature rise decreases to 9%, compared to using only water in the MEMS.

Reconstruction of Scrotal and Perineal Defects in Fournier’s Gangrene  [PDF]
Hakim Chabak, Amine Rafik, Mohammed Ezzoubi, Mounia Diouri, Na?ma Bahechar, Abdessamad Chlihi
Modern Plastic Surgery (MPS) , 2015, DOI: 10.4236/mps.2015.53005
Abstract: Fournier’s gangrene described in 1883 by Jean Alfred Fournier, still poses ethiopathogenic, evolutive and therapeutic problems. This is a therapeutic emergency; early diagnosis, medical and surgical treatments contribute to reducing mortality rate. Tissue defect engendered by infection and/or by its excision requires morphological and functional reconstruction. The choice of the reconstruction technique depends on several parameters: early or delayed coverage, the size of the defect, the local capital skin and the patient’s general condition. Through this study involving 95 cases of scrotal and perineal gangrene treated at the National Center of Burns and Plastic Surgery of Ibn Rochd University Hospital of Casablanca over a period of 10 years (2004-2014), we report our approach in the surgical management of defect secondary to Fournier’s gangrene.
Hydrogeochemistry of seasonal variation of Urmia Salt Lake, Iran

Aquatic Biosystems , 2006, DOI: 10.1186/1746-1448-2-9
Abstract: Seven hundred and four samples were taken and partially analyzed for the main cations and anions. Surface water (0.5 m. depth) was analyzed for Na, K, Mg, Ca, Br and Li, and averaged 87.118 g/lit, 1.48 g/lit, 4.82 g/lit, 4.54 g/lit, 1.19 ppm and 12.7 ppm respectively for the western half of the lake. Sodium ranged between 84 to 91.2 g/lit, and showed higher concentrations in the south than in the north. This unexpected result may be caused by shallower depth in the south and a higher net evaporation effect. Calcium ranged between 4.2 to 5 g/lit, apparently slightly higher in the north. K is higher in the south, possibly due to rivers entering from south that may carry slightly higher K in solution.In the middle-range samples (0.5–5 m.), K averaged 1.43 g/lit and ranged from 1.40 to 1.46 g/lit. At this intermediate depth the distribution of K is clearly higher to the south of the causeway that is currently under construction. It is not clear whether this increase is the effect of the causeway or the effect of the salty Aji-Chay River to the east, and the Khoy salt domes to the north of the lake. At depth (5 m–10 m), K averaged 1.48 g/lit and ranged from 1.4 to 1.49 g/lit, differing only in the second decimal from the average of the middle and surface samples.Ignoring the small difference between the averages of the three sample depths, the distribution of K is highly homogeneous in the lake water due to the mixing process. Therefore causeway construction has not yet strongly affected K distribution, or it may be at the starting point. Magnesium concentration ranged from 4.6 to 5-g/lit, and was elevated in the south. This differs somewhat compared to calcium. Lithium, with an average of 12–13 ppm, is slightly higher in the south, and has not shown any significant variation in all three seasons. Iodine was below the detection limit in the lake.Urmia Lake, geochemically, is highly uniform both to the south and north of the causeway, in both the surface and deep brines.
The Role of Background Knowledge in Foreign Language Listening Comprehension
Samad Salahshuri
Theory and Practice in Language Studies , 2011, DOI: 10.4304/tpls.1.10.1446-1451
Abstract: The role of background knowledge and topic familiarity in second language reading comprehension has been the subject of much research. Although it is assumed that learners will react similarly to listening, it should be remembered that, they are not entirely parallel skills, and most importantly, relevant researches provided conflicting results in different contexts. Besides, there is no report of such a study with Iranian learners of a foreign language. Thus, this paper reports research that describes the effects of topic familiarity on the foreign language listening comprehension, and makes an attempt to find out whether proficiency level affects recall measures of listening comprehension. To this end, an experiment was conducted with 56 students studying English at one of Iranian universities. The results of the between-within analysis of variance clearly indicated that topic familiarity affected the scores of recall measures and the course-level groups revealed a consistent increase in comprehension scores. There was also no interaction effect: subjects regardless of their level scored higher on the familiar passage. The researcher has also left some relevant issues to some further research at the end of the paper.
Asymptomatic Bacteriuria in Pregnant Women
Samad Hazhir
Urology Journal , 2007,
Abstract: Introduction: The aim of this study was to evaluate the frequency of bacteriuria in pregnant women referred to the medical centers of Tabriz, Iran, for prenatal care. Materials and Methods: A total of 1100 healthy pregnant women who were referred to 50 medical centers in Tabriz for a regular prenatal care were evaluated for bacteriuria. Results: The frequency of asymptomatic bacteriuria was 6.1%. Maternal age was lower in the women with a positive urine culture (P = .02). Asymptomatic bacteriuria had no relationship with gestational age, parity, level of education, and body mass index. Conclusion: We found a relatively high rate of bacteriuria in our cohort of asymptomatic pregnant subjects, especially the younger ones. For prevention from the complications of the asymptomatic bacteriuria in pregnant women, such as pyelonephritis, hypertension, preeclampsia, low birth weight, prematurity, septicemia, and even maternal and neonatal death, it is recommended to perform urine culture as a routine evaluation during the pregnancy.
The Professional Medical Journal , 2003,
Abstract: Present study evaluated a new factor i.e. effect of coronary artery disease (CAD) duration on plasma lipidsand lipoproteins concentration. 105 patients of atherosclerotic CAD were divided as: group-A (n=59) havingCAD duration 1 year, group=-B (n=25) and group-C (n=21) having CAD duration 3 years. In group-A, 79%patients had positive history of vegetable oil use, group-B, 68% and in group-C, 61% patients have positivehistory of vegetable oil use in their diet after onset of CAD symptomatology. Results showed that totalcholesterol (TC), LDL and LDL-C which were significantly raised in group-A and B, become nonsignificantlyraised levels in group-C when each group compared with control subject (n=35) while exceptsignificantly decreased levels (p<0.02) of HDL2-C in group-B, all other parameters (TC, triglycerides, LDL,LDL-C, VLDL-C, THDL-C and HDL-C) showed non-significant difference when compared with group-A.Non-significant difference in levels also seen in group-C when compared with group- A. Study concludedthat after 3 years of CAD duration TC, LDL and LDL-C levels were decreased. However, this effect maybe depended upon vegetable oil use. While effect of CAD duration on HDL-C levels remained controversial.
Credit Risk Determinants of Bank Failure: Evidence from US Bank Failure
Abdus Samad
International Business Research , 2012, DOI: 10.5539/ibr.v5n9p10
Abstract: This paper empirically determines the significant determinants, among credit risk variables, of US bank failure. Applying the Probit Model the paper finds that among the five credit risk variables, the credit loss provision to net charge off, loan loss allowance to non-current loans, and non-current loans to loans are significant for predicting bank failures. These factors predict 76.8 percent to 77.25 of total observation correctly. The model predicts 97 out of 121 failures i.e. 80.17 percent correctly. Net charge off to loans and loan loss to non-current loans, though most reliable measures, are not significant predictors for the US bank failures during 2009.
