Radiation Measurements in Soil of Nusirate in the middle of Gaza-Strip Using Nuclear Track Detector CR-39 and Electra Plus

Because of the hazards of radon activity and its daughter products to human health, several studies were conducted to measure radiation in environment including soil and building materials. Alpha particles radiation contents of soil samples were measured using solid state nuclear track detector (SSNTD) CR-39. Soil samples were collected from the middle region of Gaza-Strip, in Nusirate area. Alpha activity per unit volume were evaluated in the sample using solid state nuclear track detector. Results showed that the activity of Alpha particles in soil has a maximum value 9.305 Bq/m3, and minimum 2.878 Bq/m3, and average is 5.244 Bq/m3. Also results using Electra Plus were discussed and compared with other published data

Endemic Gastrointestinal Anthrax in 1960s Lebanon: Clinical Manifestations and Surgical Findings

Anthrax is an ancient disease caused by the gram-positive Bacillus anthracis; recently, it has gained much attention because of its potential use in biologic warfare. Anthrax infection occurs in three forms: cutaneous, inhalational, and gastrointestinal. The last type results from ingestion of poorly cooked contaminated meat. Intestinal anthrax was widely known in Lebanon in the 1960s, when a series of >100 cases were observed in the Bekaa Valley. We describe some of these cases, introduce the concept of the surgical management of advanced intestinal anthrax, and describe some of the approaches for treatment

Radiation measurements in soil in the middle of Gaza-Strip using different type of detectors

Radon Alpha particles and its daughter products dangers effect to human health is the main motivation behind several studies of measuring radiation in environment including the soil and building material. We measured the activity of Alpha, Beta particles and Gamma Radiation in soil in the middle of Gaza Strip in general form by using five types of detectors. In our survey the middle region of Gaza Strip was divided into four areas, , included Dier El Balah (D), Mughazi (M), Buriej (B) and Nusairat (N), 40 samples where considered in the present work . The samples then were tested and the results presented in this paper. The comparison between the four regions was obtained and showed low radiation level compared with the standard level known by the IAEA and UNCEAR report (U3, U6)[3,7]. This study was conducted to provide us with measurements and extrapolations about radiation concentration in general form in soil. This would enable us to expect the health effects of radiation might cause in the future, especially from the environmental point of view

Post-graduation migration intentions of students of Lebanese medical schools: a survey study

<p>Abstract</p> <p>Background</p> <p>The international migration of physicians is a global public health problem. Lebanon is a source country with the highest emigration factor in the Middle East and North Africa and the 7th highest in the World. Given that residency training abroad is a critical step in the migration of physicians, the objective of this study was to survey students of Lebanese medical schools about their intentions to train abroad and their post training plans.</p> <p>Methods</p> <p>Our target population consisted of all students of Lebanese medical schools in the pre-final and final years of medical school. We developed the survey questionnaire based on the results of a qualitative study assessing the intentions and motives for students of Lebanese medical schools to train abroad. The questionnaire inquired about student's demographic and educational characteristics, intention to train abroad, the chosen country of abroad training, and post-training intention of returning to Lebanon.</p> <p>Results</p> <p>Of 576 eligible students, 425 participated (73.8% response rate). 406 (95.5%) respondents intended to travel abroad either for specialty training (330 (77.6%)) or subspecialty training (76 (17.9%)). Intention to train abroad was associated with being single compared with being married. The top 4 destination countries were the US (301(74.1%)), France (49 (12.1%)), the United Kingdom (31 (7.6%)) and Canada (17 (4.2%)). One hundred and two (25.1%) respondents intended to return to Lebanon directly after finishing training abroad; 259 (63.8%) intended to return to Lebanon after working abroad temporarily for a varying number or years; 43 (10.6%) intended to never return to Lebanon. The intention to stay indefinitely abroad was associated male sex and having a 2^ndcitizenship. It was inversely associated with being a student of one of the French affiliated medical schools and a plan to train in a surgical specialty.</p> <p>Conclusion</p> <p>An alarming percentage of students of Lebanese medical schools intend to migrate for post graduate training, mainly to the US. A minority intends to return directly to Lebanon after finishing training abroad.</p

Mucinous cystic neoplasms of the mesentery: a case report and review of the literature

<p>Abstract</p> <p>Background</p> <p>Mucinous cystic neoplasms arise in the ovary and various extra-ovarian sites. While their pathogenesis remains conjectural, their similarities suggest a common pathway of development. There have been rare reports involving the mesentery as a primary tumour site.</p> <p>Case presentation</p> <p>A cystic mass of uncertain origin was demonstrated radiologically in a 22 year old female with chronic abdominal pain. At laparotomy, the mass was fixed within the colonic mesentery. Histology demonstrated a benign mucinous cystadenoma.</p> <p>Methods and results</p> <p>We review the literature on mucinous cystic neoplasms of the mesentery and report on the pathogenesis, biologic behavior, diagnosis and treatment of similar extra-ovarian tumors. We propose an updated classification of mesenteric cysts and cystic tumors.</p> <p>Conclusion</p> <p>Mucinous cystic neoplasms of the mesentery present almost exclusively in women and must be considered in the differential diagnosis of mesenteric tumors. Only full histological examination of a mucinous cystic neoplasm can exclude a borderline or malignant component. An updated classification of mesenteric cysts and cystic tumors is proposed.</p

Measurement of Radon Exhalation Rate from Destroyed Building Material in the Gaza Strip

Abstract Building materials are one of the potential sources of indoor radioactivity because of the naturally occurring radionuclides in them. Radon exhalation rate is one of the most important factors for evaluation of the environmental radon level. Radon contributes more than half of the total ionizing radiation dose Indoor radon has been recognized as one of the health hazards for mankind because long-term exposure to radon increases the risk of developing lung cancer. This study aims at assessing the contribution of destroyed building materials in war 2014 towards the total indoor radon exposure to the inhabitants of in Gaza. 40 Samples have been collected from common destroyed building materials in Jabalia district. The closed-can technique has been employed in this study using solid state nuclear track detectors (CR-39). After 124 days of exposure to radon, CR-39 detectors were etched chemically by (6 N) NaOH solution at 75°C for three months and then counted under an optical microscope. Results obtained from the current study show that radon exhalation rates from concrete and asbestos have relatively high values as compared to other building materials while glass, marble and a red brick contribute less to radon exhalation rate. The average radon exhalation rate in term of area in the studied samples ranged from (86.506) mBq.m .h -1 for Concrete samples. In general, the annual effective doses from the investigated building materials are low and under the global value (from 1 to 5 mSv/y) except for Concrete and asbestos samples with average values (9.464) and (9.3528) mSv/y, respectively
