Polimorfismos de la metilenotetrahidrofolato reductasa C677T como factor de riesgo para el síndrome de ovario poliquístico en una muestra de mujeres jordanas / Methylenetetrahydrofolate Reductase C677T Polymorphisms as a Risk Factor for Polycystic Ovarian Syndrome in a Sample of Jordanian Women

Antecedentes: el síndrome de ovario poliquístico (SOP) es un trastorno endocrino reproductivo común, se puede identificar por hiperandrogenismo, oligomenorrea o anovulación y ovarios poliquísticos en la ecografía. Los polimorfismos de la metilentetrahidrofolato reductasa (MTHFR) C677T asociados con la hiperhomocisteinemia se encuentran entre los factores de riesgo del síndrome de ovario poliquístico. Objetivo: El presente estudio de casos y controles tiene como objetivo explorar la relación entre los polimorfismos C677T de la metilenotetrahidrofolato reductasa (MTHFR) como factor de riesgo y el síndrome de ovario poliquístico entre los pacientes jordanos que padecen esta enfermedad. Métodos: Se inscribieron en el estudio 306 sujetos (146 pacientes con SOP y 160 sujetos sanos como grupo de control). Se extrajo ADN de una muestra de sangre venosa extraída de cada participante para analizar los polimorfismos de MTHFR C677T utilizando la reacción en cadena de la polimerasa (PCR) en combinación con digestión con enzima de restricción (PCRRFLP). Posteriormente, los productos de PCR-RFLP se digirieron con la enzima HinfI, luego se sometieron a electroforesis en un gel de agarosa al 2%, se tiñeron y se examinaron bajo luz ultravioleta. Los niveles de homocisteína en plasma se analizaron utilizando el método ELISA. Resultados: Se observó una diferencia significativa en los niveles plasmáticos de homocisteína entre los pacientes con SOP frente a los sujetos de control y entre los diferentes polimorfismos de los pacientes con SOP. No se detectaron diferencias significativas en la distribución y frecuencia alélica de los polimorfismos MTHFR C677T en pacientes con SOP en comparación con los controles. El genotipo 677 / TT y el alelo T se asociaron con un aumento de 1,54 y 1,46 veces en la susceptibilidad al síndrome de ovario poliquístico. Conclusión: El estudio ha demostrado que el polimorfismo MTHFR T677T y el alelo T son posibles factores de riesgo de SOP entre las mujeres jordanas y pueden desempeñar un papel en la patogenia de la enfermedad

Background: Polycystic ovary syndrome (PCOS) is a common endocrine reproductive disorder, it can be identified by hyperandrogenism, oligomenorrhea or anovulation and polycystic ovaries on ultrasound. Methylenetetrahydrofolate Reductase (MTHFR) C677T polymorphisms associated with hyperhomocysteinemia are among the risk factors for PCOS. Objective: The present case control study aims to explore the relationship between Methylenetetrahydrofolate Reductase (MTHFR) C677T polymorphisms as a risk factor and PCOS among Jordanian patients suffering from this disease. Methods: 306 subjects (146 PCOS patients and 160 healthy subjects as a control group) were enrolled in the study. DNA was extracted from venous blood sample withdrawn from each participant for analyzing MTHFR C677T polymorphisms using Polymerase Chain Reaction (PCR) in combination with restriction enzyme fragment length polymorphism (PCR-RFLP). Later, PCR-RFLP products were digested with hinfI enzyme, then, electrophoresed on a 2% agarose gel, stained and examined under UV light. Plasma homocysteine levels were assayed using ELISA method. Results: A significant difference was observed in plasma homocysteine levels among PCOS patients versus the control subjects and in between the different polymorphisms of PCOS patients. No significant difference was detected in the distribution and allelic frequency of MTHFR C677T polymorphisms in PCOS patients compared to the controls. 677/TT genotype and T allele were associated with 1.54 and 1.46 folds increase in the susceptibility for PCOS. Conclusion: The study has shown that MTHFR T677T polymorphism and T allele are possible risk factors for PCOS among Jordanian women and may play a role in the pathogenesis of the disease.

Mid Urethral Slings for the Treatment of Urodynamic Stress Incontinence in Overweight and Obese Women: Surgical Outcomes and Preoperative Predictors of Failure.

PURPOSE: We evaluated mid urethral sling outcomes in overweight and obese patients compared to normal weight patients and identified risk factors for failure in this population. MATERIALS AND METHODS: Records of 688 women between January 2004 and July 2017 were retrospectively reviewed. Patients received urodynamic studies, 1-hour pad test, Urogenital Distress Inventory-6 and Incontinence Impact Questionnaire-7, and were divided into normal weight, overweight and obese. Objective cure at 1 year was defined as no involuntary urine leakage during filling cystometry and pad test less than 2 gm. Subjective cure was established by negative response to question 3 on Urogenital Distress Inventory-6. McNemar's test, chi-square test, Mann-Whitney U and Fisher's exact test were used for paired categorical variables. Independent samples t-tests and paired t-test were used for continuous parametric variables. Multivariate logistic regression was used to identify risk factors for failure. RESULTS: Objective and subjective cure in normal, overweight and obese patients was 91.4% and 89.1%, 87.5% and 86%, and 76% and 70.1%, respectively. There was no difference in surgical complications. Obese patients had worse quality of life scores preoperatively and postoperatively. Risk factors in obese patients with failed mid urethral sling included 66 years old or older (OR 2.02, 1.56-3.98), menopause (OR 4.21, 1.21-14.22), previous prolapse surgery (OR 4.57, 2.36-8.52), diabetes (OR 2.79, 1.61-5.99) and intrinsic sphincter deficiency (OR 5.06, 3.08-9.64). CONCLUSIONS: Obese women with mid urethral sling had lower objective and subjective cure at 1 year and worse quality of life scores compared to normal and overweight women. Risk factors for failure include age, diabetes, menopause, previous prolapse surgery and intrinsic sphincter deficiency.

Clinical and Sonographic Evaluation of Postmenopausal Bleeding (PMB) Followed by Diagnostic and/or Therapeutic Hysteroscopy and Guided Biopsy in Jordanian Hospitals.

Background and Objectives: The goal of this study was to evaluate the clinical sonographic evaluation of postmenopausal bleeding (PMB) followed by diagnostic and/or therapeutic hysteroscopy and guided biopsy in Jordanian hospitals. Materials and Methods: A retrospective multi-centric study was performed in hospitals in Al-Karak and Amman from 2014-2016. The study recruited 189 cases to evaluate the aetiology of postmenopausal bleeding. Atrophic endometrium was observed as a major cause of postmenopausal bleeding according to histopathology. The cases were also distributed according to parity in which nulliparous patients were observed. Results: Hysteroscopy was observed to be effective for the diagnosis of postmenopausal bleeding. Conclusion: There is a need to assess more approaches for the diagnosis of postmenopausal bleeding among women.

Single incision anterior apical mesh and sacrospinous ligament fixation in pelvic prolapse surgery at 36 months follow-up.

OBJECTIVE: To compare the clinical efficacy, recurrence, complications and quality of life changes 3 years after Elevate-A/single incision mesh surgery anterior apical (SIM A) and sacrospinous ligament fixation (SSF) in the management of pelvic organ prolapse (POP). MATERIALS AND METHODS: A prospective cohort study, 139 women, underwent transvaginal surgery for anterior and/or apical POP > stage 2, 69 patients had SIM A and 70 patients had SSF. The objective cure was defined as POP ≤ stage 1 anterior, apical according to POP-Q. Subjective cure is patient's negative feedback to question 2 and 3 of pelvic organ prolapse distress inventory 6 (POPDI-6). Patient's satisfaction was reported using validated quality of life questionnaires. Multi-channel urodynamic study was used to report any voiding problems related to the prolapse surgery 6 months after surgery. RESULTS: 119 patients completed a minimum of 3 years follow-up. 89.8% is the overall prolapse correction success rate for SIM A and 73.3% for SSF group (p = 0.020), and 96.6% versus 73.4% at the anterior vaginal compartment respectively (p ≤ 0.001). Statistically significant difference was noticed in apical compartment with 98.3% with SIM A and 85.0% with SSF (p = 0.009). The subjective success rate, 86.4% in the SIM A and 70.0% in the SSF arm (p = 0.030) was significantly noted. Only, Pelvic Organ Prolapse Distress Inventory-6 (POPDI-6) showed significant improvement. Operation time and intra-operative blood loss tend to be more with SIM A. CONCLUSION: SIM A has better 3 years objective and subjective cure rate than SSF in the anterior and/or apical compartment prolapse.

Low incidence of bacteriuria with outpatient flexible cystoscopy.

AIM: To evaluate the incidence of bacteriuria after outpatient diagnostic flexible cystoscopy utilising sterile catheter urine collection technique in women. MATERIALS AND METHODS: This is a prospective observational study on 78 women who had outpatient flexible cystoscopy for various indications between March and December 2011. Urine for culture was collected by transurethral catheterisation three to five days before cystoscopy, and a second urine sample was collected five to seven days after the procedure. Antibiotic prophylaxis was not administered. Significant bacteriuria was defined as 10(2)  cfu/mL or more of a single organism cultured. RESULTS: Five (6.4%) had significant bacteriuria and were asymptomatic. The most common organism cultured was Escherichia coli in 4 (80%) of the infected women. No other cystoscopic complication was observed. The mean age was 54.7 years (range 27-80), mean parity was 2.8 (range 0-7). In the study group, 54 (69.2%) women were postmenopausal, 9 (11.5%) had diabetes mellitus, 42 (53.8%) had pelvic organ prolapse and 22 (28.2%) had a prior hysterectomy. Most common indications for cystoscopy were hematuria and recurrent UTI, 48 (61.5%) and 22 (28.2%) women respectively. The cystoscopic findings were normal in 59 (75.6%) women. The procedure was completed within five minutes in all participants. CONCLUSION: The incidence of bacteriuria following outpatient flexible cystoscopy is low.
