| 1 | Prevalence of intestinal parasitic infections and its relationship with socio-demographics and hygienic habits among male primary schoolchildren in Al-Ahsa,Saudi Arabia显示文摘Objective:To investigate the prevalence of different intestinal parasitic infections among male primary schoolchildren in Al-Ahsa,Saudi Arabia,and to explore the possible relative socioeconomic, environmental and behavioural sanitary correlates.Methods:A cross-sectional descriptive study was performed.A total of 1 289 male students aged from 7 to 12 years were selected randomly from 20 urban and 12 rural primary schools by multistage sampling method. Data collection was carried out by self administered questionnaire form to the parents/guardians of students and included inquires about socio-demographics,environmental conditions,and behavioural sanitary habits.Stool analysis was carried out to examine the presence of intestinal parasitic infections.Results:Overall prevalence of parasitic infections was 27.2%,more among rural students.Frequently encountered infections included Entamoeba histolytica/dispar(8.2%), Giardia lamblia(6.5%),Entamoeba coli(4.0%) and Enterobius vermicularis(1.6%).Logistic regression revealed that lower maternal educational level and occupational status,low family income,big family size,poor personal hygienic practices and positive history of previous intestinal infections among family members increased the likelihood of infections.Conclusions: Although of low magnitude,intestinal parasitic infections still represent a public health concern among male schoolchildren in Al-Ahsa region.Socio-demographic and poor personal hygienic habits are the main predictors for these infections. | Hamdan Ibrahim Al-Mohammed Tarek Tawfik Amin Elsayed Aboulmagd Hatem Refaat Hablus Burhan Omar Zaza | 2010 | Asian Pacific Journal of Tropical Medicine2010，3，11： | 3 |

| 3 | Cutaneous leishmaniasis in Al Hassa, Saudi Arabia: Epidemiological trends from 2000 to 2010显示文摘Objective: To study epidemiological trends related to cutaneous leishmaniasis (CL) in Al Hassa, an endemic area in Saudi Arabia. Methods: This retrospective study included the spatial/ temporal analysis of the reported cases of CL using the available surveillance database for the disease at the regional Vector Control Unit, from 2000 to 2010. Results: The incidence of CL was declining at a stable rate especially during the last 3 years of the study (2008-2010). An interesting finding was the percentage of expatriates affected was increasing over the last 10 years compared to that of the Saudis. Conclusions: A definite declining trend in the incidence of CL was observed in Al Hassa. Further studies are warranted to assess whether special public health measures are needed for better control of CL in expatriate populations in Saudi Arabia. | Tarek Tawfik Amin Hamdan Ibrahim Al-Mohammed Feroze Kaliyadan Balghonaim Salah Mohammed | 2013 | Asian Pacific Journal of Tropical Medicine2013，6，8： | 0 |
| 4 | 计算机断层成像(CT)结肠镜:结肠息肉直径和体积的自动测量与手工测量技术的比较——体外研究显示文摘[目标]:研究不同和相同读片人对息肉直径进行体外自动测量时所得结果的一致性。[方法]:用16排CT扫描两个模型(QRM和Whiting模型),两个模型都包含有直径和体积已知的模拟息肉。两位读片人用三种方法来估计息肉的直径:软件测量(手工)、手工边界识别(半自动)及自动软件分割(全自动)。[结果]:对同一读片人,当使用全自动方法时,95%一致性极限范围最小(QRM范围:0.39mm~0.48mm;Whiting范围:0.24mm~0mm)。手工估计测量的极限范围大约比全自动方法要大10倍(QRM范围:3.57mm~3.21mm,Whiting范围:3.2mm~2.02mm)。全自动方法对体积的估计范围最小(范围:24.2mm3~24.1mm3;而半自动测量的范围为97.9mm3~102.9mm3)。对不同读片人,当使用全自动方法时,测得直径的一致性范围最小(QRM范围:0.12mm;Whiting范围:0.16mm),而使用手工方法的一致性范围大约是全自动方法的18倍(QRM范围:2.87mm;Whiting范围:2.18mm)。[结论]:通过全自动方法来测量息肉直径和体积在技术上是可行的,可使不同和相同读片人的测量结果实现更高的一致性。 | David Burling Steve Halligan Mary E.Roddie Justine McQuillan DCR(R) Lesley Honeyfield DCR(R) Hamdan Amin Jamshid Dehmeshki Stuart A.Taylor MD Elizabeth G.McFarland | 2006 | 中国医疗器械信息2006，12，1： | 0 |
