Int J Womens Health 2020 3;12:965-974. Epub 2020 Nov 3.

Obstetrics and Gynecology Department, Kasr Alainy, Faculty of Medicine, Cairo University, Egypt, Algezeera Hospital, Egypt.

Background: Many expressions were used to define the defect that is seen by ultrasound after cesarean section (CS) namely scar defect, niche, isthmocele, uterine pouch or diverticula.

Objective: To compare the accuracy of 2 dimensional sonohysterography (2D SHG) to 3 dimensional sonohysterography (3D SHG) in evaluating cesarean section uterine scar depth (D), base width (BW), width (W) and residual myometrial thickness (RMT) in women with secondary infertility and establishment of a standard criteria; Alalfy simple rules for scar assessment.

Patients And Methods: This was an observational cross-sectional comparative study that was conducted on women who presented with secondary infertility and were candidates for intracytoplasmic sperm injection (ICSI) and giving a history of a previous cesarean section. Assessment of uterine scar in each woman was performed using 2D transvaginal ultrasound with sonohysterography (SHG) followed by 3D transvaginal with SHG with evaluation of niche depth, width, RMT, niche BW and RMT/depth ratio. The study was conducted at Algezeera hospital, Egypt.

Results: The present study revealed that 3D ultrasound with SHG is superior in evaluation of the RMT and niche width prior to ICSI providing better characterization of the scar niche.

Conclusion: Scar niche should be assessed by a combined integrated 2D SHG and 3D SHG scan with the specific geometrical and anatomical considerations, Alalfy simple rules for scar niche assessment that involvemeasurement of niche depth, (Base width) BW, width, RMT and RMT/depth ratio in sagittal plane, RMT in coronal plane / niche width in coronal plane ratio (ratio less than 1 denotes scar weakness with more liability for dehiscence).

Prevalence of vitamin D deficiency in Egyptian patients with pregnancy-induced hypertension.

J Perinat Med 2020 Jul;48(6):583-588

Department of Obstetrics and Gynecology, Kasr Al-Ainy Faculty of Medicine, Cairo University, Cairo, Egypt.

Background Hypertensive disorders of pregnancy can cause severe maternal and fetal acute morbidity and mortality. Women with pre-eclampsia have been found to have alterations in calcium and vitamin D metabolism. There are conflicting results regarding the role of vitamin D deficiency in the development of pre-eclampsia. The aim was to compare 25 (OH) D level in patients with pre-eclampsia, eclampsia and normotensive pregnant women as well as to study the prevalence of Vitamin D deficiency among the 3 groups. Patients and methods Two hundred patients with pre-eclampsia, 100 with eclampsia and 200 normotensive pregnant controls were compared as regards vitamin D level. Results Mean 25(OH)D level was lower in the pre-eclampsia (14.8 ± 5.4 ng/mL) and in the eclampsia group (10.5 ± 1.6 ng/mL) than in the pregnant controls (19.5 ± 6.5 ng/mL) (P = 0.002). This difference was only significant between the eclampsia group and the pregnant controls (P = 0.02). All eclampsia cases had vitamin D insufficiency as compared to 17.5% in the pre-eclampsia group and 39.5% in the control group. Deficiency of vitamin D (<12 ng/mL) was 47.5% in the pre-eclampsia group, 80% in the eclampsia group and only 10.5% in the control group (P = 0.035). Conclusion Vitamin D deficiency is highly prevalent among Egyptian pregnant females. Our study supports the hypothesis that low vitamin D level can play a role in the development of pre-eclampsia and eclampsia. Thus, supplementation might prevent or delay the development of pre-eclampsia and eclampsia especially in patients at a high risk.

Prenatal ultrasound findings of holoprosencephaly spectrum: Unusual associations.

Prenat Diagn 2020 04 10;40(5):565-576. Epub 2020 Feb 10.

Clinical Genetics Department, Human Genetics and Genome Research Division, National Research Centre, Cairo, Egypt.

Objective: The objective of this study is to evaluate the prenatal diagnosis, postnatal characteristics, and the spectrum of associated findings in fetuses with holoprosencephaly (HPE).

Methods: Fetal neurosonograms, postnatal assessment, and chromosomal analysis were performed in a cohort of 25 fetuses with HPE.

Results: The prevalence of HPE in high-risk pregnancies was 4.4:10 000. The alobar subtype was the most frequently encountered, with 17 cases (68%). Interestingly, among them, four cases (16%) presented with the rare agnathia-otocephaly complex. Chromosomal abnormalities were detected in 11 cases (44%), the most frequent being trisomy 13 in seven cases (five alobar, one semilobar, and one lobar HPE), followed by trisomy 18 in two cases with semilobar HPE. One case of alobar HPE had 45, XX, t(18;22) (q10;q10), -18p karyotyping, and one case of semilobar HPE was associated with triploidy. Facial malformations in HPE spectrum ranged from cyclopia, proboscis, and arrhinia that were associated with the alobar subtype to hypotelorism and median cleft that were frequent among the semilobar and lobar subtypes. Associated neural tube defects were identified in 12% of cases.

Conclusion: Our study illustrates the clinical and genetic heterogeneity of HPE and describes different chromosomal abnormalities associated with HPE.

Prophylactic vaginal dinoprostone administration six hours prior to copper-T380A intrauterine device insertion in nulliparous women: A randomized controlled trial.

Contraception 2020 03 4;101(3):162-166. Epub 2019 Dec 4.

Department of Obstetrics and Gynecology, Faculty of Medicine, Cairo University, Cairo, Egypt.

Objective: To determine the effectiveness of 3 mg vaginal dinoprostone administered six hours prior to copper intrauterine device (IUD) insertion compared to placebo in increasing ease of insertion and reducing insertion pain among nulliparous women.

Study Design: This was a single-center double-blinded randomized controlled trial (RCT). We randomly divided the two hundred nulliparous women requesting a copper T380A IUD to receive 3 mg vaginal dinoprostone or placebo six hours before IUD insertion. The primary outcome was provider ease of insertion. Patients reported their perceived insertion pain using a 10 cm visual analog scale (VAS). We also reported number of failed IUD insertions.

Results: Baseline characteristics were similar between groups. Ease of insertion score was lower in dinoprostone group than placebo group (3.6 ± 2.5 vs. 5.4 ± 2.8; p < 0.01) denoting easier insertion for clinicians in dinoprostone group. Mean pain score during copper IUD insertion was lower in dinoprostone group (3.7 ± 2.3 vs. 5.0 ± 2.8; p < 0.01). Failed IUD insertion occurred in two cases of dinoprostone group (2%) versus four cases in control group (4%) (p-value; 0.68).

Conclusions: Although vaginal dinoprostone administration six hours prior to copper IUD insertion in nulliparous women leads to an easy IUD insertion, we do not routinely advise it as the reduction in IUD insertion pain scores with vaginal dinoprostone lacked clinical significance.

Implications: In settings where it is feasible to provide dinoprostone vaginally six hours before copper IUD insertion, clinicians will find insertion easier, and nulliparous women may experience somewhat less pain during the procedure. Where waiting six hours is practical, this may prove to be useful.

J Matern Fetal Neonatal Med 2019 Oct 21:1-7. Epub 2019 Oct 21.

Obstetrics and Gynecology Department, Helwan Faculty of Medicine, Helwan University, Helwan, Egypt.

Postpartum hemorrhage that occurs frequently with placenta previa is one of the causes of maternal mortality in 14% in developing countries. To assess efficacy of cervical inversion as a tamponade in controlling bed of placenta in cases of placenta previa. A prospective randomized controlled study was conducted among a total of 240 pregnant women with placenta previa (120 subjected to Alalfy modified cervical inversion technique plus hemostatic sutures and 120 was not subjected cervical inversion and only was subjected to hemostatic sutures in Obstetrics and Gynecology Department at Suez Canal University hospital, Helwan University and Algezeerah hospital for a planned cesarean section). The mean intraoperative blood loss, the intraoperative time, and the postoperative hemoglobin show a statistically significant difference between cases with placenta previa who were exposed to cervical inversion in comparison to cases that had no cervical inversion with a -value <.001. Modified cervical inversion (Alalfy technique) as a tamponade when added to hemostatic sutures to the placental bed is an easy, rapid, and efficient procedure that can decrease the amount of blood loss, time needed to stop bleeding per bed, total operative time, also it can decrease the need for blood transfusion.

J Matern Fetal Neonatal Med 2017 Jul 3;30(13):1540-1543. Epub 2016 Oct 3.

a Department of Clinical and Chemical Pathology , Faculty of Medicine, Cairo University , Cairo , Egypt and.

Background: Prenatal screening for group B Streptococcus (GBS) colonization can reduce the incidence of neonatal GBS infections. We aimed to improve the screening-based approach of GBS in a limited resources antenatal care clinic by using Strep B Granada™ Biphasic Broth.

Methods: This study included 80 pregnant women between 35 and 37 weeks of gestation, who attended the antenatal care clinic of Kasr El-Aini University Hospital from November 2013 to January 2014. Two high vaginal swabs were collected, then transported using Amies transport medium. One vaginal swab was processed by conventional culture-based methods on 5% sheep blood agar plates. The other swab was immersed in 3 mL selective enrichment broth (Granada™ Biphasic Broth bioMérieux).

Results: Among 80 pregnant women, GBS was detected in 9 (11.25%) of the studied cases within 18-24 hours. Detection of orange-red colonies in GBS Granada broth was 100% specific for the presence of beta-hemolytic group B streptococci.

Conclusion: Using Granada biphasic broth media was easy, affordable and shortened the turnaround time needed for the detection of GBS by conventional culture methods. Routine screening of pregnant women for vaginal GBS colonization by Granada™ Biphasic broth would allow properly timed prenatal antimicrobial prophylaxis to prevent possible neonatal infections.

Prevalence of human papilloma virus (HPV) and its genotypes in cervical specimens of Egyptian women by linear array HPV genotyping test.

Infect Agent Cancer 2016 17;11. Epub 2016 Feb 17.

Department of obstetrics& gynecology, Faculty of Medicine, Cairo University, Cairo, Egypt.

Background: The association of human papillomavirus (HPV) with cervical cancer is well established.

Aim: To investigate HPV genotype distribution and co-infection occurrence in cervical specimens from a group of Egyptian women.

Methods: A group of 152 women with and without cervical lesions were studied. All women had cervical cytology and HPV testing. They were classified according to cytology into those with normal cytology, with squamous intraepithelial lesions (SIL) and invasive squamous cell carcinoma (SCC). Cervical samples were analyzed to identify the presence of HPV by PCR, and all positive HPV-DNA samples underwent viral genotype analysis by means of LINEAR ARRAY HPV Genotyping assay.

Results: A total of 26 HPV types with a prevalence of 40.8 % were detected. This prevalence was distributed as follows: 17.7 % among cytologically normal females, 56.5, 3.2, and 22.6 % among those with LSIL, HSIL and invasive SCC respectively. Low-risk HPV types were detected in 81.8 % of the cytologically-normal women, in 5.7 % of those in LSIL women, and in 14.3 % of infections with invasive SCC, while no low-risk types were detected in HSIL. High-risk HPV types were detected in 18.2 % of infections in the cytologically normal women, 14.3 % of infections in LSIL, and in 21.4 % of invasive lesions. The probable and possible carcinogenic HPV were not detected as single infections. Mixed infection was present in 80 % of women with LSIL, in 100 % of those with HSIL, and in 64.3 % of those with invasive SCC. This difference was statistically significant. HPV 16, 18 and 31 were the most prevalent HR HPV types, constituting 41.9, 29.03 and 12.9 % respectively, and HPV 6, 62 and CP6108 were the most prevalent LR HPV types constituting 11.3, 9.7 and 9.7 % respectively.

Conclusion: These data expand the knowledge concerning HPV prevalence and type distribution in Egypt which may help to create a national HPV prevention program. HPV testing using the LINEAR ARRAY HPV Genotyping assay is a useful tool when combined with cytology in the diagnosis of mixed and non-conventional HPV viral types.

Combined Vaginal Pelvic Floor Electrical Stimulation (PFS) and Local Vaginal Estrogen for Treatment of Overactive Bladder (OAB) in Perimenopausal Females. Randomized Controlled Trial (RCT).

Urology 2015 Sep 30;86(3):482-6. Epub 2015 Jun 30.

Department of Obstetric and Gynecology, Cairo University, Giza, Egypt.

Objective: To evaluate the efficacy of combined vaginal pelvic floor electrical stimulation (PFS) and local vaginal estrogen in treatment of female overactive bladder (OAB).

Material And Methods: This is a randomized controlled trial carried out on 315 perimenopausal females with OAB who were randomly allocated into 3 equal groups. Group A underwent PFS using vaginal probes twice weekly for 12 sessions. Group B received local vaginal estrogen, whereas group C received both PFS and local estrogen. All patients were evaluated by a voiding diary, quality-of-life questionnaire, vaginal examination, urine analysis, blood sugar, ultrasonography, and urodynamic study before and after therapy. Patients were followed up 1 week, 3, and 6 months post-therapy. The analyzed variables included day and night time frequency, incontinence episodes, urgency, quality of life, detrusor overactivity), and functional bladder capacity). Outcome measure was urge incontinence.

Results: Within each group, there was a statistically significant improvement in all variables after treatment. Improvement of urgency was better in group C than in groups A and B (P = .000, .009). Improvement of incontinence was better in groups A and C than in group B (P = .005, .004). Follow-up showed worsening of symptoms within 6 months in all groups except incontinence in group C.

Conclusion: Vaginal PFS and estrogen found to be effective in treating OAB symptoms in perimenopausal females. Estrogen seems to augment the effect of PFS especially in the treatment of urgency incontinence and can delay its recurrence.

Screening for Chlamydia trachomatis in Egyptian women with unexplained infertility, comparing real-time PCR techniques to standard serology tests: case control study.

BMC Womens Health 2015 Jun 2;15:45. Epub 2015 Jun 2.

Department of obstetrics & gynecology, Faculty of Medicine, Cairo University, Cairo, Egypt.

Background: To study the prevalence of Chlamydia infection in women with primary and secondary unexplained infertility using ELISA technique for antibody detection and real time, fully automated PCR for antigen detection and to explore its association with circulating antisperm antibodies (ASA).

Methods: A total of 50 women with unexplained infertility enrolled in this case control study and a control group of 44 infertile women with a known cause of infertility. Endocervical specimens were collected for Chlamydia antigen detection using PCR and serum samples for antibodies detection. Circulating anti-sperm antibodies were detected using sperm antibody Latex Agglutination tests.

Results: The overall prevalence of Chlamydial infection in unexplained infertility cases as detected by both ELISA and PCR was 40 % (20/50). The prevalence of current Chlamydial genital infection as detected by real-time PCR was only 6.0 % (3/50); two of which were also IgM positive. Prevalence of ASA was 6.0 % (3/50); all were sero-negative for anti-C.trachomatis IgM and were PCR negative.

Conclusion: The incidence of Chlamydial infection in Egyptian patients with unexplained infertility is relatively high. In the setting of fertility investigations; screening for anti. C.trachomatis antibodies using ELISA, and treatment of positive cases should be considered. The presence of circulating ASA does not correlate with the presence of old or current Chlamydia infection in women with unexplained infertility.

Prevalence of Trichomonas vaginalis infection among Egyptian women using culture and Latex agglutination: cross-sectional study.

BMC Womens Health 2015 7;15. Epub 2015 Feb 7.

Department of Obstetrics and Gynecology, Faculty of Medicine, Cairo University, Cairo, Egypt,

Background: This is a cross-sectional study carried out in the Obstetrics and Gynecology Department at Kasr Al- Ainy Cairo University Hospitals.

Methods: One thousand female patients in the child bearing period (age 18-45 yrs) were included in this study. These females were non-pregnant and non-menstruating with no douching or intercourse for at least 2-3 days, no use of antibiotics, anti-protozoal or steroids for the past 15 days complaining of vaginal discharge with or without itching, burning sensation or both. Vaginal swabs were obtained from all patients for examination by direct wet mount examination, Giemsa staining, Modified Diamond culture and latex agglutination test Kalon) to detect the presence of Trichomonas vaginalis infection.

Results: The prevalence of trichomonas infection was 50 cases, latex agglutination test detected 50 positive cases, 30 of which were also positive by culture, and only 10 were detected both by Giemsa staining and by wet mount. The wet mount, Giemsa staining and Kalon latex test had sensitivities of 33.3, 33.3% and 100% respectively while their specificities were 100%, 100% and 97.9% respectively.

Conclusion: Screening tests should be done routinely to depict cases of T. vaginalis infection and should be included in the control programs of sexually transmitted infections. Although wet mount is not a sensitive method for diagnosis of T. vaginalis yet, it is a good positive one. Staining is only useful when there is heavy T. vaginalis infection. Latex agglutination is a highly sensitive, simple, rapid and cost effective test. It provides results within 2-3 minutes and it has the potential for use in screening and diagnosis of T. vaginalis infection.

The relationship between low maternal serum vitamin D levels and glycemic control in gestational diabetes assessed by HbA1c levels: an observational cross-sectional study.

BMC Pregnancy Childbirth 2014 Oct 13;14:362. Epub 2014 Oct 13.

Obstetrics and Gynecology Department, Cairo University, Cairo, Egypt.

Background: A great association between vitamin D deficiency and type 2 diabetes mellitus has been suggested in literature. During pregnancy, this deficiency is even more critical. It appears that vitamin D insufficiency during pregnancy may be associated with maternal hazards. The aim of this study was to assess the relation between the levels of 25-hydroxy-cholecalciferol (vitamin D), and the glycemic control in pregnant women.

Methods: An observational cross-section study including 160 pregnant women between 20-40 years in age, in their third trimester, divided into two equal groups. First group consisted of 80 women with established diagnosis of gestational diabetes and the second group with proved normal blood glucose levels. We assessed vitamin D in serum, fasting blood glucose, serum insulin and glycosylated hemoglobin (HbA1c) levels and we depicted the insulin sensitivity using the Quantitative insulin sensitivity check index (Quicki). The results were collected and statistically correlated.

Results: The mean vitamin D levels were 46.61 ± 6.087 and 47.25 ± 10.181in controls and women with gestational diabetes mellitus (GDM) respectively. The fasting insulin levels were significantly higher in the group with GDM with a mean of 18.51 ± 6.44 compared to 8.95 ± 2.52 in the control group.The correlation coefficient (r) between HbA1c levels and Vitamin D level was -0.492 with a P value <0.05. Similar associations were also found with the fasting blood sugar levels (r = -0.386) and with Quicki values (r = -0.250). Vitamin D levels correlated significantly with the fasting blood glucose, the fasting serum insulin and the HbA1c levels, the P value in all these correlations were <0.05. The P value with Quicki results was 0.064.

Conclusions: There is a statistically significant negative correlation between the glycemic control and vitamin D levels in serum in the whole study population. The effect of adequate vitamin D replacement on glycemic control was not studied in our work correlation. We suggest larger scale studies addressing this issue.

Oral antioxidants supplementation for women with unexplained infertility undergoing ICSI/IVF: randomized controlled trial.

Hum Fertil (Camb) 2015 Mar 3;18(1):38-42. Epub 2014 Jul 3.

Department of Obstetrics and Gynaecology, Faculty of Medicine, Cairo University , Cairo , Egypt.

Objective: Good oocyte quality and maturity are important prerequisites for high fertilization and implantation rates in IVF/ICSI treatment cycles. Reactive oxygen species (ROS) are produced within ovarian follicles, especially during the ovulation process, and increased ROS activity may be a cause of impaired oocyte maturation and higher rate of failure of IVF/ICSI cycles.

Study Design: RCT evaluating the effect of antioxidant supplementation on ICSI/IVF outcomes. Two hundred and eighteen women with unexplained subfertility undergoing IVF/ICSI were randomized into two groups. The study group (n = 112) received daily oral antioxidants in the form of multivitamins and minerals (amino acid chelated) while the control group (n = 106) did not. Main outcomes were number of mature metaphase II (MII) oocytes and clinical pregnancy rate.

Results: There were no significant changes between the groups as regards age, BMI, basal FSH, number of mature (MII) oocytes (12.7 ± 9.4 vs. 13.2 ± 8.6, P = 0.7) and clinical pregnancy rate per woman randomized (38% vs. 34%; [OR = 1.2; 95% CI, 0.70-2.11].

Conclusion: Oral antioxidants in the form of a combination of multivitamins and minerals (amino acid chelated) did not improve oocyte quality and pregnancy rates in women with unexplained infertility undergoing IVF/ICSI treatment.
