AimIn this study, we aimed to analyze the genetic and acquired risk factors for deep vein thrombosis (DVT) of the lower extremities among Sudanese women.MethodsA total of 136 women were enrolled in the study, including 75 DVT patients and 61 healthy controls. Demographic and clinical data were collected using a specific questionnaire. Citrated blood samples of patients and controls were used for coagulation assays, and DNAs isolated from EDTA-blood samples were used for the detection of Factor V Leiden and prothrombin G20210A mutations using multiplex polymerase chain reaction-restriction fragment length polymorphism analysis.ResultsBoth gene mutations were found to be absent from all 136 subjects, and therefore did not account for the incidence of DVT in Sudanese women. Of the 75 DVTs, 70 (93.3%) were localized in the left leg and 5 (6.7%) in the right leg. Additionally, 84% of the DVTs were proximal and 16% were distal. Among the 75 patients, 22 (29.33%) were postpartum, 7 (9.33%) were pregnant, and 46 (61.33%) were nonpregnant. Levels of prothrombin fragment 1+2, prothrombin time, activated partial thromboplastin time, and D-dimer were significantly higher in DVT patients than in healthy controls (P<0.0001).ConclusionRisk factors that most significantly affected patients in the 18–45 years age group were pregnancy and oral contraceptive usage, whereas those that most significantly affected patients in the 66–90 years age group were immobility, heart disease, and history of DVT.

BACKGROUND: Recurrent pregnancy loss is classically defined as the occurrence of three or more consecutive pregnancy loss. Recurrent pregnancy loss affects from 1-5% of the reproductive age couples. This diagnosis is both emotionally challenging and confusing for most couples, as the definitive diagnosis using conventional evaluations is found in fewer than half of the couples experiencing repeated loss. AIM: The purpose of this study was to define the association between Factor V Leiden G1691A, Prothrombin G20210A, MTHFC677T mutations and recurrent pregnancy loss in a group of Sudanese women. MATERIALS AND METHODS: This a retrospective analytical case control study was carried out at Omdurman Maternal Hospital, Sudan between July 2013 to July 2015. Consent was obtained from the ethical committee of the Faculty Research Board and Hospital of Omdurman Maternity Hospital (Sudan). The study included a hundred pregnant females with a history of recurrent spontaneous abortion as the (case group) and ninety-five healthy reproductive Sudanese women as the (control group). The data was collected with the help of a structured questionnaire and direct interview to collect information. Identification of point mutation in factor V Leiden G1691A, prothrombin G20210A and MTHF C677T gene by polymerase chain reaction was performed. The odds ratio and the 95% confidence interval (95%CI) were calculated for the presence of mutation case group and the control group and analyzed by SPSS program, version 17.0. RESULTS: The frequency of prothrombin G20210A, MTHFC677T, was low overall, except for the Factor V Leiden G1691A. The differences between patients and controls had no statistical significance (P- Value>0.05). CONCLUSION: Our study confirms the low prevalence of inherited thrombophilias in Sudanese populations and it is unlikely that the tested thrombophilias play a role in the pathogenesis of recurrent pregnancy loss in the Sudanse population.Therefore, we conclude that the low prevalence of Factor V Leiden, prothrombin G20210A and MTHFC677T in Sudanese women with RPL and does not play a role in the pathogenesis of recurrent pregnancy loss among our population.

Background:In some cancer cells, the OGG1 gene is somatically mutated and highly populated. This study was conducted to examine whether OGG1 rs1052133 polymorphism is associated with the genetic background of chronic myelogenous leukaemia (CML) in Sudan.Methods:A total of 332 CML patients and 70 healthy controls were included in this study. Overall, the genotypes (P=0.0000) and allele (C vs. G, P=0.0007) differed considerably in the frequencies of OGG1 rs1052133 polymorphism between CML patients and controls. Our study is the first to evaluate the association of polymorphism with CML risk with OGG1 rs1052133.Results:A statistically significant association was observed between the genotype distribution of OGG1 rs1052133 polymorphism and CML (P=0.0000) patients. A similar result was also observed in the allele distribution (C vs. G, P=0.0007) compared with healthy controls when compared OGG1 rs1052133 genotypes with CML stages.Results:Genotype and allele frequencies of OGG1 rs1052133 among CML patients. A statistically significant association was observed between the genotype distribution of the OGG1 rs1052133 polymorphism and CML patients (P=0.0000). A similar result was also observed in the allele distribution (C vs. G, P=0.0007) compared with healthy controls with stages of CML in OGG1 rs1052133 genotypes.Conclusion:The results suggest that single nucleotide polymorphism in the gene involved in the restoration of DNA base excision (OGG1 rs1052133) can play a key role in the risk of appearance of CML. To clarify the role of OGG1 in the genetic basis of CML, further case control with larger sample sizes and fine-mapping is required.

Introduction. Bloodstream infections (BSI) among patients with hematological malignancies (HM) could predispose them to higher morbidity and mortality for various underlying conditions. Several microorganisms, either pathogenic or opportunistic normal human flora, could cause severe bacteremia and septicemia. While conventional methods have their own limitations, molecular methods such as next-generation sequencing (NGS) can detect these blood infections with more reliability, specificity, and sensitivity, in addition to information on microbial population landscape. Methodology. Blood samples from HM patients ( n = 50 ) and volunteer blood donor control individuals with no HM ( n = 50 ) were subjected to 16S rRNA gene amplification using standard PCR protocols. A metagenomic library was prepared, and NGS was run on a MiSeq (Illumina) sequencer. Sequence reads were analyzed using MiSeq Reporter, and microbial taxa were aligned using the Green Genes library. Results. 82% of the patients showed BSI with Gram-negative bacteria as the most predominant group. E. coli comprised a major chunk of the bacterial population (19.51%), followed by K. pneumoniae (17.07%). The CoNS and Viridans Streptococci groups are 17.07% and 14.63%, respectively. Other major species were S. aureus (9.75%), P. aeruginosa (7.31%), A. baumannii (4.87%), E. cloacae (4.87%), and P. mirabilis (4.87%). 34.14% of the cases among patients showed a Gram-positive infection, while 14.63% showed polymicrobial infections. Conclusion. Most of the BSI in patients were characterized by polymicrobial infections, unlike the control samples. Molecular methods like NGS showed robust, fast, and specific identification of infectious agents in BSI in HM, indicating the possibility of its application in routine follow-up of such patients for infections.

Introduction: Tonsillectomy is a common surgical procedure done by otolaryngologists. Tonsillectomy is a relatively simple procedure. The concept of implementing it as a day case operation has become increasingly popular. Material and Methods: This is a cross sectional study done in Alahsa city, eastern province, Saudi Arabia during the period from January 2014 to March 2015,This study reported the postoperative hemorrhage after Bipolar diathermy and Cold dissection surgical techniques to evaluate the incidence of the hemorrhage and to identify the possible risk factors associated with its occurrence. Results: Postoperative bleeding occurred in 45 (3.6%) out of 1232 patients. Post-tonsillectomy hemorrhage according to operation technique was significantly higher among patients who underwent bipolar diathermy than cold dissection technique (p < 0.05). Conclusion: Bleeding after operation by bipolar diathermy technique was occurring more frequently within the first five days. Hemoglobin level was significantly decreased in posttonsillectomy hemorrhage.
