Ovarian Reserve Following Laparoscopic Ovarian Cystectomy vs Cyst Deroofing for Endometriomas.

STUDY OBJECTIVE: Because laparoscopic ovarian cystectomy of endometriomas is known to adversely impact patient ovarian reserve, the search for other techniques of surgical management is ongoing. The present study was undertaken to evaluate laparoscopic cyst deroofing as a feasible alternative. STUDY DESIGN: Prospective, randomized clinical trial (Canadian Task Force classification I). SETTING: University maternity hospital. PATIENTS: Women diagnosed with unilateral or bilateral ovarian endometriomas. INTERVENTIONS: Patients were managed with either laparoscopic ovarian cystectomy or cyst deroofing. MEASUREMENTS AND MAIN RESULTS: A total of 122 women with endometriomas were randomized to either laparoscopic cystectomy (group 1) or laparoscopic cyst deroofing (group 2). The primary endpoint was the effect on ovarian reserve based on changes in anti-Müllerian hormone (AMH) values. At 1 month postsurgery, anti-Müllerian hormone values were significantly decreased (p < .001) from preoperative values, from 4.25 ± 0.87 ng/mL to 1.66 ± 1.02 ng/mL in group 1 and from 4.2 ± 1.69 ng/mL to 2.15 ± 1.48 ng/mL in group 2. In addition, antral follicle count and ovarian volume decreased significantly (p < .001) in both groups by 1 month postsurgery. The decreases in these 3 parameters were more significant (p < .001) in group 1 than in group 2. CONCLUSION: Laparoscopic cyst deroofing of endometriomas appears to be a promising alternative to laparoscopic cystectomy, with less postoperative decrease in ovarian reserve; however, the higher rate of endometrioma recurrence warrants future clinical research to determine the optimal surgical management of endometriomas.

Rectal vs. sublingual misoprostol before cesarean section: double-blind, three-arm, randomized clinical trial.

PURPOSE: The commonest surgical procedure for women is cesarean delivery. Postpartum hemorrhage and intra-operative blood during cesarean delivery is a major concern to all obstetricians. This study was conducted to assess the efficacy of the adjuvant use of misoprostol and oxytocin in decreasing intra-operative blood loss in cesarean delivery. METHODS: This was a double-blinded randomized clinical trial including 636 term pregnant woman scheduled for cesarean section at Ain Shams University Maternity Hospital, Cairo, Egypt, between February 2013 and February 2014. Participants received either 400-µg misoprostol rectally or sublingually or placebo before cesarean section together with 5-IU oxytocin IV. The main outcome measure was intra-operative blood loss. Difference between the three groups was analyzed using one-way ANOVA test (for numeric variables) and Chi-square test (for categorical variables). P < 0.05 was considered statistically significant. RESULTS: Intra-operative blood loss was higher in patients who did not receive misoprostol (Placebo Group) (295-1075 ml, 641.7 ± 135.7) than those who received it, regardless the route of administration, rectal (135-830 ml, 457.5 ± 140.7; P < 0.001), and sublingual (135-680 ml, 357.8 ± 129.7; P < 0.001). In addition, sublingual route was associated with significantly lower estimated intra-operative blood loss compared to rectal administration (P < 0.001). CONCLUSIONS: Misoprostol with oxytocin is an effective drug-combination for decreasing intra-operative blood loss during cesarian section with clinical superiority to sublingual over rectal route.

Monitoring and Detection of Insecticide Resistance in Spodoptera frugiperda (Lepidoptera: Noctuidae): Evidence for Field-Evolved Resistance in Egypt.

Spodoptera frugiperda (J.E. Smith) (Noctuidae: Lepidoptera) is a notable insect pest that invades major cereal crops, causing significant damage and loss. Resistances of 2nd instar larvae of two Egyptian field populations of S. frugiperda, collected from the Fayoum and Giza governments, were measured against eight insecticides, including traditional insecticides (profenofos and cypermethrin), bio-insecticides (emamectin benzoate, spinosad, and Bacillus thuringiensis), and insect growth regulators (IGRs) (lufenuron, diflubenzuron, and methoxyfenozide). In addition, the synergistic effects of three synergists (Piperonyl butoxide (PBO), diethyl maleate (DEM), and triphenyl phosphate (TPP) were assessed, and the activities of detoxification enzymes (acetylcholine esterase (AChE), cytochrome P-450 (CYP-450), carboxylesterase (CarE), and glutathione-s-transferase (GST) were also determined. Resistance surveillance revealed that the Fayoum field population showed moderate resistance to cypermethrin (RR = 5.75-fold), followed by spinosad (RR = 2.62-fold), and lufenuron (2.01-fold). On the other hand, the Giza population exhibited significant resistance to cypermethrin only (RR = 3.65-fold). Our results revealed that emamectin benzoate was the most effective insecticide, with an LC50 value of 0.003 mg/L for the Fayoum population and 0.001 mg/L for the Giza population, compared to the susceptible strain (0.005 mg/L). Among the biological insecticides, Bacillus thuringiensis was the least toxic insecticide of all the tested strains. Synergism assays indicated that DEM and TPP had the most synergistic effect on spinosad (SR = 8.00-fold for both), followed by PBO (SR = 5.71-fold) for the Fayoum population, compared with spinosad alone. The assay of detoxification enzymes showed that GST activity significantly (p < 0.05) increased in the two field strains compared to the susceptible strain. However, no significant changes were observed among the tested strains in CYP-450, CarE, or AChE. The findings of this study provide substantial insights into tracking and managing the development of insecticide resistance in S. frugiperda in Egypt.

A preliminary pilot randomized crossover study of uzara (Xysmalobium undulatum) versus ibuprofen in the treatment of primary dysmenorrhea.

OBJECTIVE: Preliminary evaluation of efficacy and safety of uzara use in treatment of moderate and severe primary dysmenorrhea in comparison to ibuprofen. MATERIALS AND METHODS: This randomized, comparative two way cross-over study comprised 60 single female students at Faculty of Medicine, Ain Shams University, Egypt, aged 19-28 years with moderate (n = 46) or severe (n = 14) primary dysmenorrhea. Participants were randomized to take either uzara (80 mg/8 hours for two doses, then 40 mg/8 hours) then ibuprofen (400 mg/6 hours) in two subsequent cycles or vice versa. The pain intensity, using VAS, was recorded immediately before taking the medication (0 hour) and after 4, 12, 24, 48-60, 96-120 hours. Main outcome measures included effectiveness of pain relief defined as drop of VAS to 3 or less, patient's global evaluation of the drug, absence from school, the use of a rescue medication, and, in those who continued the treatment, the pain intensity difference (PID) at different points after start of medication and its sum (SPID). RESULTS: Uzara was comparably effective to ibuprofen (78.3% vs. 86.7% of cycles; respectively), with comparable rates of effectiveness on global evaluation (being around 50% for either drug), and rates of school absences (11.7% vs. 13.3%; respectively). The need for rescue medication was different (18.3% and 10%; respectively), albeit with no statistical significance. The means of PID at different time points and SPID were comparable, with significantly lower average mean of VAS scores compared to that felt with no medication (1.6 vs. 6.8, p<0.001). Side effects were less with uzara than ibuprofen (0% vs. 8.3%, p<0.05). CONCLUSIONS: Uzara might be as effective as ibuprofen in management of primary dysmenorrhea but with less side effects. These findings need to be confirmed by a properly designed trial with a larger sample size. TRIAL REGISTRATION: Current Controlled Trials ISRCTN25618258.
