Arabic translation, cultural adaptation, and validation of Australian Pelvic Floor Questionnaire in a Saudi population.

INTRODUCTION AND HYPOTHESIS: The aims of the study were the translation, cultural adaptation, and validation of self-administered Australian Pelvic Floor Questionnaire (APFQ) on a Saudi population. METHODS: The translation and cultural adaptation was performed in 854 women over 18 and not pregnant who agreed to answer the Arabic version of the questionnaire. The content/face validity, internal consistency (reliability), and construct validity (factor analysis) were assessed. Statistical analysis was carried out using SPSS 24.0 statistical software. RESULTS: The Cronbach's alpha results were above 0.8 for the questionnaire's overall reliability (bladder function: 0.877, bowel function: 0.834, prolapse symptoms: 0.784, sexual function: 0.762) showing adequate internal consistency reliability and high statistical significance. A statistically significant correlation was observed among the 40 items of the questionnaire. The issue of multicollinearity was not found, and the determinant of the correlation matrix was 0.001. A value of > 0.5 was achieved when the Kaiser-Meyer-Olkin and Bartlett's tests measured 0.806 and the Bartlett's test of sphericity was statistically significant χ2 (780) = 4150.46 (p < 0.001). The values of loading indicate that all 4 factors (bladder function, bowel function, prolapse symptoms, sexual function) contributed to each of their items. CONCLUSIONS: This study provides the Arabic version of the self-administered APFQ as a reliable and valid instrument for evaluating symptom severity and impact of pelvic floor dysfunction on the quality of life of Arabic women. It also will enable the researchers from Arab countries to use this instrument to assess pelvic floor dysfunction prevalence in their settings.

Analysis of class I and II aberrations in Iraqi childhood acute myeloid leukemia using filter paper cards.

The lack of molecular diagnosis in the field of cancer in Iraq has motivated us to perform a genetic analysis of pediatric acute myelogenous leukemia (AML), including class I and II aberrations. Peripheral blood or bone marrow cells were collected from 134 AML children aged ≤15 years. Flinders Technology Associates (FTA) filter paper cards were used to transfer dried blood samples from five Iraqi hospitals to Japan. DNA sequencing was performed to identify class I mutations. Nested RT-PCR was used to detect class II aberrations, except that MLL rearrangement was detected according to long distance inverse-PCR. NPM1 and FMS-like tyrosine kinase 3-internal tandem duplication (FLT3-ITD) mutations were analyzed by GeneScan using DNA template. Among 134 Iraqi pediatric AML samples, the most prevalent FAB subtype was M2 (33.6 %) followed by M3 (17.9 %). Class I mutations: 20 (14.9 %), 8 (6.0 %), and 8 (6.0 %) patients had FLT3-ITD, FLT3-TKD, and KIT mutations, respectively. Class II mutations: 24 (17.9 %), 19 (14.2 %), and 9 (6.7 %) children had PML-RARA, RUNX1-RUNX1T1, and CBFB-MYH11 transcripts, respectively. MLL rearrangements were detected in 25 (18.7 %) patients. NPM1 mutation was detected in seven (5.2 %) cases. Collectively, approximately 30 % of AML children were proved to carry favorable prognostic genetic abnormalities, whereas approximately 10 % had high FLT3-ITD allelic burden and needed a special treatment plan including allogeneic hematopoietic stem cell transplantation. Acute promyelocytic leukemia (APL) was frequent among Iraqi pediatric AML. It is likely that molecular diagnosis using FTA cards in underdeveloped countries could guide doctors towards an appropriate treatment strategy.

Frequent coexistence of RAS mutations in RUNX1-mutated acute myeloid leukemia in Arab Asian children.

BACKGROUND: RUNX1 mutation plays an important role in adult leukemic transformation. However, its contribution to the development of childhood leukemia remains unclear. In the present study, we analyzed point mutations of RUNX1 gene in children and adolescents with acute myeloid leukemia (AML) from Iraq and Jordan. PROCEDURE: Bone marrow and/or peripheral blood samples were collected from 178 patients of Arab Asian ethnicity (aged ≤17 years) newly diagnosed with AML: 145 samples from Iraq and 33 samples from Jordan. Direct DNA sequencing was performed on six genes including RUNX1 gene (exons 3-8). RESULTS: RUNX1 point mutations were identified in 10 (5.6%) of 178 patients. One patient possessed biallelic mutations of RUNX1 gene. C-terminal area was the predominant site of RUNX1 mutations (eight in C-terminal and two in N-terminal). Patients with RUNX1 mutations were significantly older than those with wild-type of the gene. Additionally, AML M0 subtype was more frequently found in patients with RUNX1 mutations. Both RUNX1 mutations and RAS mutations were identified in 4 of 10 children. Three patients with RUNX1 mutation had FLT3-ITD. On the other hand, 36 (21.4%) and 25 (14.9%) of 168 patients with wild-type of the gene had a RAS mutation and FLT3-ITD, respectively. Eight of 10 patients with RUNX1 mutations died of hematological relapse. CONCLUSION: The incidence of RUNX1 mutations in Arab Asian children and adolescents with AML was 5.6%. Further studies are required to clarify whether RAS mutations contribute to the development of pediatric AML associated with RUNX1 mutations.

Comprehensive genetic analyses of childhood acute leukemia in Iraq using next-generation sequencing.

Background: Molecular analyses in hematological malignancies provide insights about genetic makeup. Probable etiological factors in leukemogenesis could also be disclosed. Since genetic analyses are still primitive in Iraq, a country of repeated wars, we conceived of performing next-generation sequencing (NGS), to disclose the genomic landscape of acute lymphoblastic leukemia (ALL) and acute myeloid leukemia (AML) among a cohort of Iraqi children. Methods: Dried blood samples were collected from Iraqi children with ALL (n=55), or AML (n=11), and transferred to Japan where NGS was done. Whole-exome, whole-genome, and targeted gene sequencings were performed. Results: Somatic point mutations and the copy number variations among Iraqi children with acute leukemia were comparable with those in other countries, and cytosine-to-thymine nucleotide alterations were dominant. Strikingly, TCF3-PBX1 was the most recurrent fusion gene (22.4%) in B-cell precursor ALL (B-ALL), and acute promyelocytic leukemia (AML-M3) was subtyped in 5 AML cases. Additionally, a high frequency of RAS signaling pathway mutations was detected in children with B-ALL (38.8%), along with 3 AML cases that carried oncogenic RAS. Conclusions: Apart from disclosing the high frequency of TCF3-PBX1, NGS confirmed our previous finding of recurrent RAS mutations in Iraqi childhood acute leukemia. Our results suggest that the biology of Iraqi childhood acute leukemia is in part characteristic, where the war-aftermath environment or geography might play a role.

Genetic evaluation of childhood acute lymphoblastic leukemia in Iraq using FTA cards.

BACKGROUND: Genetic examination of childhood leukemia has not been available in Iraq. We here report the frequency of TEL-AML1, E2A-PBX1, MLL-AF4, and BCR-ABL chimeric transcripts in 264 Iraqi children newly diagnosed with acute lymphoblastic leukemia (ALL), using FTA cards impregnated with bone marrow aspirate or whole blood. PATIENTS AND METHODS: The diagnosis of ALL was made according to standard French-American-British morphologic criteria. Based on the results of storage temperature and duration, most of the FTA samples were preserved at 4°C for up to 6 weeks in five Iraqi hospitals and then transferred to Japan for molecular analysis. Nested reverse transcription-polymerase chain reaction was adopted for the analysis. RESULTS: TEL-AML1 chimeric transcript product was found in 32 (12.1%) of 264 ALL patients. Eleven (4.2%) patients, 4 (1.5%) patients, and 11 (4.2%) patients had E2A-PBX1 mRNA, MLL-AF4 mRNA, and BCR-ABL mRNA, respectively. One patient had both TEL-AML1 and E2A-PBX1 fusion genes. The incidence of TEL-AML1 in Iraqi ALL children appears to be similar to or slightly higher than those of Jordan (12%) and Kuwait (7%). The prevalence and clinical findings of ALL patients with either E2A-PBX1 or BCR-ABL were comparable to the data reported elsewhere. CONCLUSION: International collaboration via FTA cards may be helpful to improve diagnosis and management of patients with hematological malignancies in low-income and underdeveloped countries.

Imaging findings of atypical leiomyoma of urinary bladder simulating ureterocele.

Bladder leiomyomas are relatively rare benign tumors of the bladder. They represent <0.5% of all urinary bladder tumor. In the literature, only about 250 cases reported worldwide. They are commonly found in middle-aged females. Patients present with variety of clinical presentations with predominance of obstructive urinary symptoms. Ultrasound bladder is the first preferable diagnostic tool. Definitive diagnosis is made by histopathological examination. Surgical excision is almost highly effective, leaving a low recurrence rate. We report a 34-year-old male who presented with complaints of dysuria and incomplete voiding. Ultrasound showed a cystic fluid-filled bladder mass (ureterocele), which was excised through a transurethral resection. The histopathologic diagnosis was bladder leiomyoma.

Prevalence of pelvic floor dysfunction in women in Riyadh, Kingdom of Saudi Arabia: A cross-sectional study.

OBJECTIVE: Pelvic floor dysfunction has a high prevalence among women worldwide. However, in the Kingdom of Saudi Arabia, it is underreported. Thus, we aimed to estimate the prevalence and risk factors of pelvic floor dysfunction in women in the Kingdom of Saudi Arabia. METHODS: We conducted a cross-sectional study on literate non-pregnant women aged ⩾18 years who agreed to participate in our survey. We used the validated and translated Australian pelvic floor questionnaire and conducted a multivariate logistic regression analysis to assess the risk factors of pelvic floor dysfunction. RESULTS: A total of 824 participants completed the questionnaire. While 60.2% of the participants had pelvic floor dysfunction, 67.7% reported signs of bowel dysfunction. Urinary dysfunction, prolapse, and sexual dysfunction were present in 44.1%, 67.7%, and 55.4% of the participants, respectively. Age, high body mass index, chronic medical illness, heavy weight lifting, and multiparity were found as the risk factors of bladder function problems. Meanwhile, chronic medical illness, heavy weight lifting, and multiparity were found as the risk factors of bowel dysfunction and prolapse. Age group and marital status were the independent factors associated with sexual dysfunction. CONCLUSION: We noted a high rate of pelvic floor dysfunction in the Kingdom of Saudi Arabia, which calls for the need to provide holistic approaches for the prevention and management of pelvic floor dysfunction among women.
