AIM: To assess the prevalence of nutritional disorders in children with inflammatory bowel disease(IBD) in Saudi ***: The data from a national cohort of children newly diagnosed with IBD between 2003 and 2012 were analyzed. The diagnosis of IBD and the differentiation between Crohn's disease(CD) and ulcerative colitis(UC) were confirmed by gastroenterologists according to the standard criteria. The body mass index(BMI) of each child [weight(kg)/height^2(m)] was calculated at the time of diagnosis. The World Health Organization standards and references were used and the BMI for age > +1 and alysis was performed to investigate any age-related variation in the prevalence of nutritional status between children all of the children were Saudi nationals, and 68(57%) of the UC and 150(59%) of the CD children were males. A positive history of anorexia at the time of diagnosis was found in 30(25%) patients with UC and 99(39%) patients with CD. The prevalence of thinness was 31%, 35% and 24% in children with IBD, CD and UC, respectively, with a significantly higher prevalence of thinness in children with CD than in children with UC(P = 0.037) only in the age group of 10-17 years(P = 0.030). The prevalence of overweight was 16 %, 15% and 20 % in the children with IBD, CD and UC, respectively, indicating a higher prevalence in UC that was statistically significant only in the age group of 10-17 years(P = 0.020). CONCLUSION: A high proportion of children with IBD presented with overweight instead of the classical underweight. Awareness of this finding is important for patient care.

Open Journal of Pediatrics 2024年第2期14卷 255-265页

作者： Turki Salah aldeen Bukhari Abdullah Yahya aldhban Anas abdulrahman alqasem Dona Jamal al Hatlani Hareth aldosaimani Hamad A. al Madi khalid alqahtani Prince Sultan Military Medical City Riyadh Saudi Arabia Emergency Department Disaster Medicine and Emergency Preparedness Prince Sultan Military Medical City Riyadh Saudi Arabia Emergency Department Asir Central Hospital Abha Saudi Arabia

Objectives: The primary objective was to characterize the range of Knowledge, Attitude, and Practice (KAP) of Helmet use in children amongst parents to prevent head injuries and death. Methods: This is a cross-sectional study, done by online survey using a snowball sampling technique, the number of included responses were 386 parents (Male and female) living in Riyadh Aged 21 - 60 years old or above. Results: The study showed that there is a difference in Parents’ belief in the importance of helmet use while riding a Bicycle vs Motorcycle/Quad bike and that was affected by parents’ education level, almost all the people who answered the survey (76.7%) agree that it is important for their children to wear a helmet when riding both a Bicycle and a Motorcycle or Quadbike with a cumulative percentage of (93.8%). And almost all agreed on multiple approaches to help increase helmet use be it by forcing rental shops to give out helmets, forcing sellers to recommend the use of helmets, increasing awareness campaigns, and imposing fines for not wearing helmets. Conclusions: This study is the first to explore Family helmet use while riding Bicycles and Motorcycles/Quad bikes. although Parent’s belief in the importance of helmet use for their children was high, it is clear that the level of practice is low. With that the risk of head injuries might be high, our findings suggest that safety interventions for increasing pediatric helmet use are needed to increase helmet use and reduce the risk of head injury and hospitalization.

Glanzmann Thrombasthenia: Managing Gingival Bleeding Triggered by Tooth Eruption—A Rare Case Report

引用

Case Reports in Clinical Medicine 2024年第8期13卷 283-291页

作者： Nahla A. abdulrahman Motaz A. Atia Nada A. Abdelwahab Malaz M. Mustafa Department of Pediatric Dentistry University of Khartoum Khartoum Sudan Department of Pediatric Dentistry National Ribat University Khartoum Sudan Department of Pediatric Dentistry and Orthodontic Sciences King Khalid University Abha Saudi Arabia

Glanzmann thrombasthenia (GT) is a rare and often underdiagnosed congenital bleeding disorder caused by mutations in the genes encoding glycoproteins GPIIb or GPIIIa, resulting in platelet dysfunction. Inherited in an autosomal recessive manner, GT is characterized by the inability of platelets to aggregate. Clinically, it presents with mucocutaneous bleeding, such as easy and extensive bruising, severe epistaxis, menorrhagia, gingival bleeding, postpartum hemorrhage, and unexpected bleeding following procedures, despite a normal platelet count. We present a case involving a 6-year-old male patient who experienced spontaneous gingival bleeding for the past 4 weeks due to the eruption of his first permanent molars. The bleeding was particularly severe at night, disrupting the child’s sleep. The patient had been diagnosed with GT at the age of 16 months. Dental management was pursued, and the use of tranexamic acid mouthwash, combined with meticulous oral hygiene, resulted in an excellent response.

Sixty eyes of 30 patients（16 males and 14 females; age： 21-41 y） with mild, non-progressive（stages 1-2） keratoconus were enrolled. Refraction, uncorrected distance visual acuity（UDVA） and corrected distance visual acuity（CDVA）, flat and steep keratometry readings, and adverse events were evaluated preoperatively and postoperatively. Data were collected preoperatively and postoperatively at 3 mo, 1, 2, 3, 4, and 5 y follow-up visits after combined non-topography-guided PRK with CXL was performed. all patients had at least 5 y of ***： all study parameters showed a statistically significant improvement at 5 y over baseline values. The mean follow-up time was 68.20±4.71 mo（range： 60-106 mo）. Patients showed a significant improvement in UDVA from 1.24±0.79 log MAR prior to combined non-TG-PRK＋CXL to 0.06±0.15 log MAR postoperatively at the time of their last follow-up visit. CDVA significantly increased from 0.06±0.19 log MAR preoperatively to 0.03±0.12 log MAR postoperatively. A significant decrease in the mean spherical equivalent（SE） refraction was observed from-2.28±1.8 to-0.79±0.93 diopters（D）（P〈0.05）, and the manifest sphere decreased from-1.62±1.23 to-0.27±0.21 D（P=0.001）. The manifest cylinder significantly decreased from-1.73±0.86 to-0.29±0.34 D postoperatively（P=0.001）. The mean steep keratometry was 45.13±1.32 vs 47.28±2.12 D preoperatively（P〈0.05）, and the preoperative mean steepest keratometry（Kmax） 48.6±3.1 was reduced significantly to 46.8±2.9 postoperatively（P〈0.05）. CONCLUSION： Combined non-TG-PRK with 15 min CXL is an effective and safe option for correcting mild refractive error and improving visual acuity in patients with mild stable keratoconu

International Journal of Digital Earth 2019年第10期12卷 1133-1150页

作者： Noora khalid saleem Ullah Sheikh Saeed Ahmad Asad ali Farrukh Chishtie Department of Space Science Institute of Space TechnologyIslamabadPakistan Department of Environmental Sciences Fatima Jinnah Women UniversityRawalpindiPakistan

Worldwide, forest degradation is a serious environmental issue, and inPakistan, forest wealth is depleting at the highest rate in South Asia. Toensure sustainable development goals of environmental stewardship,social development and economic growth, a sound monitoring andregulatory mechanism is essential for tracking forest cover changes. Thisstudy aims to quantify the decline of forest reserves and associatedtemperature variations in a relatively unexplored biodiversity hotspot ofIslamabad, Margalla Hills National Park (MHNP). Imagery acquired byLandsat TM (Thematic Mapper) for the year 1992, 2000 and 2011 areused to assess the spatial and temporal changes occurred over the lasttwo decades (from 1992 to 2011). A robust hybrid-classification routineis implemented to monitor the changes in forest cover and ANOVAalong with Tukey’s HSD (Honestly Significant Difference) test is used totest the significance of temperature variation associated with a shift inland cover classes. The results showed a significant growth insettlements, agricultural area and barren soil whereas water body, lowervegetation, scrub and pine forest are diminishing. In both decades, thetemperature alteration associated with a change in land cover classesare statistically significant (confirmed by ANOVA and Tukey’s HSD tests)for most of the land use/land cover classes. Based on these findings, thisstudy concludes that forests are dwindling at MHNP and the degradingcondition of the forest is below par and necessitates the promotion ofconservation practices to minimize ecological disturbances.
