Background and Aims: The use of dexamethasone as an adjuvant to local anesthetic rarely has been described. Some studies have demonstrated the analgesic effect of local spinal and systemic corticosteroids in combination with bupivacaine. It works by decreasing inflammation and blocking transmission of nociceptive C-fibers and by stopping the ectopic discharge of the nerve. The aim of this randomized controlled trial was to compare the efficacy of epidural levobupivacaine alone versus a combination of levobupivacaine with dexamethasone for labor analgesia.

Material and Methods: This prospective double-blind trial included the 60 primigravidas during vaginal delivery with a cervical dilatation ≥4 cm and 50% effacement randomly assigned to one of two groups - Group A (=30): epidural levobupivacaine 0.125% in normal saline in a total volume of 15 mL and Group B (=30): epidural levobupivacaine 0.125% in normal saline combined with dexamethasone 4 mg in a total volume of 15 mL. At first request of analgesia, 10 mL of 0.125% levobupivacaine was administrated through epidural catheter. Further analgesia was provided with 8 mL of 0.125% levobupivacaine hourly. Primary outcome measure was the duration of epidural analgesia. Secondary outcome measures include pain score by Visual Analog Scale score before the block and 15 min following it, the total amount of levobupivacaine used, Apgar score and umbilical vein blood gas analysis, maternal satisfaction, and side effects recorded.

Results and Conclusion: The duration of epidural analgesia was significantly longer ( < 0.05) upon adding dexamethasone to levobupivacaine. Total epidural levobupivacaine consumption was significantly lower ( = 0.05) in Group B. There were no statistical differences between the two groups regarding hemodynamics, pain score, neonatal outcome, and complications. Epidural dexamethasone plus levobupivacaine prolongs the duration of epidural analgesia during management of labor pain with hemodynamic stability and limited maternal and neonatal adverse effects.

Biallelic variants in the NDE1 gene have been shown to occur in extreme microcephaly. Most of the patients displayed microlissencephaly but one with microhydranencephaly. We report on three sibs in which the brain MRI and CT scans demonstrated variable degree of reduced volume of cerebral hemispheres and ventriculomegaly. Further, they had agenesis of corpus callosum, cerebellar, and brainstem hypoplasia. Fetal ultrasound at 32 weeks' gestation of the third sib revealed severe micrencephaly with extensive hydranencephaly and an anomaly consistent with non cleaved (fused) thalami. Because of the fused thalami, the STIL gene was targeted initially but showed negative results. His postnatal MRI showed that the cerebral hemispheres are markedly reduced in size (with no definite frontal, parietal, or occipital lobes) and replaced by a large sac filled with CSF. An intact falx cerebri was identified. This extensive hydarencephaly led us to consider the NDE1 and to identify a novel homozygous nonsense variant (c.54G>A, p.W18*). The variability of the degree of brain malformations and the apparent fusion of the thalami were illusive and delayed the recognition of the genetic etiology. Our results provide the first antenatal description of this rare syndrome. Further, we expand the genetic architecture and the neuroradiologic phenotype of NDE1-related disorders.

BACKGROUND: Unexplained infertility is a rising problem and endometrial manipulation could be one of the solutions for enhancing the pregnancy rate and live birth rate in such circumstances.

AIMS: To evaluate the influence of local endometrial physical manipulation with specializd method for endometrial and tubal hydration (Elgazzar and Alalfy technique) on ICSI outcome and in increasing chemical, clinical, and live birth rate in ICSI after previous recurrent ICSI failure in patients with unexplained infertility.

RESULTS: When comparing group 1 (hydrotubation group) and group 2 (the control group with no intervention) with regards to the biochemical, clinical, and live birth rate, the hydrotubation group revealed higher rates and a better ICSI outcome.

CONCLUSION: Hydrotubation is useful in increasing biochemical, clinical, and live birth rates after recurrent failed ICSI trials with a specialized method for hydration of endometrium and tubes (Elgazzar and Alalfy technique).

BACKGROUND: Respiratory distress is commonly encountered among premature babies immediately after birth resulting in significant neonatal morbidity or mortality.

OBJECTIVES: To evaluate the possible correlation between three dimensional fetal lung volumes (FLVs) and neonatal respiratory outcomes.

STUDY DESIGN: A cohort study included 100 pregnant women who participated in the study and were divided into two groups; group A (n: 50 - women pregnant ±34-37 weeks) and group B (n: 50 - women pregnant ±37 to 40 weeks). A three dimensional measurement of the right fetal lung was made using virtual organ computer-aided analysis (VOCAL) software then correlated to neonatal respiratory functions namely Apgar score at birth and the occurrence of respiratory distress syndrome (RDS).

RESULTS: In group A, FLV was negatively correlated with Apgar score and the occurrence of RDS. In group B, FLV showed no statistical correlation with Apgar score and the occurrence of RDS.

CONCLUSIONS: Three dimensional fetal lung volumes might be an accurate noninvasive predictor for the development of RDS among preterm fetuses.

 This study aims to detect possible differences in fetal brain volumes between growth-restricted fetuses (FGR), small-for-gestational-age (SGA) fetuses with normal Doppler indices, and appropriate-for-gestational-age fetuses (AGA).  Three-dimensional measurements of fetal brain volume and umbilical artery and middle cerebral artery (MCA) pulsatility index (PI) and resistance index (RI) were made in 80 AGA fetuses, 68 SGA fetuses with normal Doppler indices, and 68 FGR with brain-sparing effect between 32 and 36 weeks of gestation.  MCA-PI and MCA-RI were significantly lower in FGR group compared with the other two groups ( < 0.001). Brain volume was significantly lower in SGA and FGR groups compared with AGA group ( < 0.001).  Brain volume is significantly lower in SGA and FGR groups compared with AGA group.

OBJECTIVE: To study the preconceptual & early conceptional risk factors predisposing to the development of spina bifida (SB) among Egyptian population.

STUDY DESIGN: The study involved 197 pregnant women undergoing fetal anatomy scan; 97 women proved to have fetal SB and 100 women with normal fetuses as a control group. The control group was recruited randomly in the same period from patients undergoing anatomical scan. Risk factors that might lead to SB were investigated including maternal age, gravidity, parity, residence, history of diabetes mellitus or drug intake, smoking, infections, exposure to X-ray, history of congenital anomalies in other offspring, parental consanguinity, positive family history, and folate supplementations.

RESULTS: SB affected the lumbo-sacral region in the majority of cases (89.7%). It was associated with hydrocephalus in 66 cases (68%), polyhydramnios in 12 cases (12.4%). The SB group showed significantly higher parity (p = 0.005), more frequent history of drug intake (p < 0.001), higher frequency of infection with CMV (p = 0.004), and HSV (p = 0.013) and less proportion of folate supplementation (p < 0.001).

CONCLUSION: The rate of SB in the tested group was five per 1000. Risk factors were lack of folate supplementation and history of antiepileptic drugs intake.

OBJECTIVE: To examine the histological structure and vascularity of uterine septa in patients with unexplained primary infertility and patients with recurrent pregnancy loss (RPL).

DESIGN: Case-control study (Canadian Task Force classification II-2).

SETTING: Kasr Al Aini Hospital, Cairo University, Egypt.

PATIENTS AND INTERVENTIONS: A total of 41 patients with uterine septa presenting with either unexplained primary infertility or RPL underwent 3-dimensional (3D) and power Doppler (PD) ultrasound to calculate the septum volume, septal vascularization index (VI), and myometrial VI. Hysteroscopically removed septa were examined histologically for myometrial and fibrous tissue content.

MEASUREMENTS AND MAIN RESULTS: Septal characteristics differed between the primary infertility group (24 patients) and the RPL group (17 patients). Mean septal VI was significantly higher in the RPL group compared with the infertility group (18.39% ± 7.57% vs 11.67% ± 4.56%; p = .003), as was septal myometrial area (20.74% ± 5.97% vs 13.57% ± 5.55%; p < .001). In both groups, septal VI was strongly correlated with myometrial VI and myometrial content, but not with fibrous tissue content.

CONCLUSION: Uterine septa of patients with RPL are more vascularized and contain more muscular tissue compared with those of patients with primary unexplained infertility.

OBJECTIVE: To study whether fetal main pulmonary artery (MPA) Doppler indices can predict the development of neonatal respiratory distress syndrome (RDS).

STUDY DESIGN: This prospective cross-sectional study included pregnant women between 34 and 38+6 weeks gestation. The diagnostic accuracy of MPA Doppler measurements (systolic/diastolic (S/D) ratio, peak systolic velocity (PSV), pulsatility index (PI), resistance index (RI) and acceleration time/ejection time (At/Et)) for diagnosis of neonatal RDS was tested.

RESULT: Of the 698 eligible fetuses, 55 (7.87%) developed neonatal RDS. PSV, PI, RI and At/Et were positively correlated with gestational age. The strongest correlation was found with At/Et (r=0.602, P<0.001). PI and RI were significantly higher, whereas At/Et and PSV were significantly lower in fetuses that developed RDS. A cutoff value of 0.305 for At/Et predicted the development of RDS (sensitivity: 76.4%; specificity: 91.6%).

CONCLUSION: Development of neonatal RDS can be predicted using the MPA At/Et with high sensitivity and specificity.

OBJECTIVE: To correlate vitamin D level in Egyptian mothers with that of their newborns, and examine risk factors related to maternal vitamin D deficiency.

METHODS: A cross-sectional study was carried out at the university teaching hospital in Cairo, Egypt. Serum 25(OH) D levels were measured by enzyme-linked immunosorbent assay in 135 pregnant women at ≥37 weeks' gestation immediately before delivery and in cord blood of their newborns.

RESULTS: The levels of serum 25(OH) D were 32.6 ± 21.4 ng/ml in mothers and 16.7 ± 10 ng/ml in their newborns. Maternal vitamin D level was strongly correlated with that of the newborns (r = 0.7, p < 0.0001). Maternal vitamin D deficiency/insufficiency and neonatal vitamin D deficiency/insufficiency were encountered in (40%, 28.9% and 60%, 32.6% respectively). Maternal vitamin D levels showed significant correlations with maternal body mass index (BMI; r = -0.201, p = 0.021), gestational age at delivery (r = 0.315, p ≤ 0.0001), fish consumption (r = 0.185, p = 0.032), educational level (r = 0.29, p = 0.001), and skin exposure (r = 0.247, p = 0.004).

CONCLUSION: Maternal vitamin D levels strongly correlate with neonatal levels. Maternal vitamin D deficiency is a real problem in Egypt; this is generally related to high BMI, low fish consumption, low educational level, and limited skin exposure.
