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.

Validation of a method for Characterization of Ethanol in Water by HS-GC-FID to Serve the Traceability of Halal measurements

引用

Green and Sustainable Chemistry 2024年第2期14卷 17-28页

作者： Adel B. Shehata abdulrahman R. Al Askar mohammed A. Al Rasheed abdulrahman m. Al Zahrany Fahd A. Al Kharraa Sowailem A. Al Sowailem Chemistry Department/National measurement and Calibration Center (NmCC) Saudi Standards Metrology and Quality Organization (SASO) Riyadh Kingdom of Saudi Arabia

The determination of the ethanol content in food products is of fundamental importance for HALAL certification. In this work, an analytical method for the determination of ethanol in water by headspace gas chromatography with flame ionization detector (HS-GC-FID) has been developed and validated for the use in characterization of ethanol reference materials. The validation study was carried out in the linear calibration range 100 - 1500 mg/kg using the NIST SRm 2900, nominal 95.6%. The studied performance characteristics of the method were the limit of detection, LOD, the limit of quantification LOQ, selectivity, linearity, precision, recovery and bias. The validation results showed that the method is selective, precise, accurate and free from any significant bias. The LOD and LOQ were 1.27 and 3.86 mg/kg respectively and the estimated expanded uncertainty was 2% indicating that the method is fit for the purpose of certification of ethanol in water reference materials.

Antibacteria Activity of Peganum harmala and Haloxylon salicornicum Leaves Extracts

引用

Advances in microbiology 2024年第2期14卷 122-136页

The use of antibiotics in humans and animals has been marked as a significant step in health due to their effectiveness in controlling and treating bacterial infections. The misuse and overuse of antibiotics have been identified as risk factors for bacterial resistance since microorganisms adapt and develop mechanisms to defend against antibiotics. According to the Centers for Disease Protection and Control (CDC), around 23,000 individuals die every year in the United States due to antibiotic resistance complications. As a result, a demand for alternative treatments has been a goal for scientists as the microbes adapt to selective pressure. The aim of this study is to test the antibacterial activity of leaf extracts of Peganum harmala and Haloxylon salicornicum on both Gram-positive and Gram-negative bacteria on various mediums. The results of the study showed that both P. harmala and H. salicornicum inhibited the bacterial growth in two different media. The results were also compared with different common antibiotics used in both human’s and animal’s fields and showed a promising outcome as alternative antibiotics.
