Abdominal Delivery

Hypothesis/aims of study. The frequency of surgical abdominal delivery in Russia, as in the world, continues to grow, reaching 29.3% in 2017. Operative vaginal delivery is an alternative to abdominal delivery in the second stage of labor. This study was aimed at analyzing the outcome of labor for mothers and newborns using different operative vaginal delivery methods. Study design, materials and methods. We studied 293 cases of childbirth in the period from 2015 to 2018. Three groups were distinguished: (I) the main group consisting of 172 women delivered by the operation of applying obstetric forceps (OF); (II) the comparison group including 85 patients delivered by the operation of vacuum extraction (VE) with the fetal head being near the pelvic floor; and (III) the control group comprising 34 cases of vaginal birth without use of instrumental delivery. In group I, 114 patients were delivered by the low forceps operation (subgroup IA), and 60 individuals by the mid forceps operation (subgroup IB). Results. Vaginal lacerations were found in 21.3% of cases in group I, less often less often in groups II (10.6%, p 0.05) and III (2.9%, p 0.05). Vaginal hematoma occurred in one patient of group III (2.9%) and three women of group I (1.7%, p 0.05). There were no cases of damage to the anal sphincter. The greatest blood loss was recorded in subgroup IB (554 44.9 ml), when compared to subgroup IA (473 20.7 ml; p 0.05), group II (418 24.9 ml; p 0.05), and group III (347 33.4 ml; p 0.05). There were no differences in blood loss between the outlet OF and VE groups (p 0.05). Most newborns were born in good condition (84.5%, 77.6%, and 88.2% of cases in groups I, II, and III, respectively). Cephalohematoma in newborns was more common after VE (32.9%) than after OF (9.2%, p 0.01) and in control (5.9%, p 0.01). No retinal hemorrhage was recorded in newborns. There were no significant differences in the frequency of children being transferred to the childrens hospital (7.5%, 9.4%, and 8.8% of cases in groups I, II, and III, respectively; p 0.05). Conclusion. The use of OF is an effective and safe method of vaginal operative delivery. It does not increase the fetal injury rate, the frequency of newborn cephalohematoma being 3.5 times less than with VE. Complications of OF and VE (except for a greater number of vaginal lacerations in cases of OF), blood loss, and the course and duration of the postpartum stay in the maternity ward are comparable.

Background: Symptomatic Uterine leiomyomata may lead to many symptoms including abnormal uterine bleeding, mass pressure effects and infertility. Myomectomy is an option for conservative management, however, it is associated with some disadvantages, mainly increased intra-operative blood loss. Intra-myometrial vasopressin injection during myomectomy is an effective method to decrease the intraoperative bleeding due to its vasoconstrictor effect. Octreotide Acetate (OA) is another vasoconstrictor agent that have not been tested for gynaecologic indications. The current study was conducted to assess the efficacy of local injection of OA in reducing blood loss during conventional abdominal myomectomy, and to compare it with local instillation of vasopressin.Methods: 60 cases with symptomatic leiomyomata were recruited and planned for abdominal myomectomy, they were divided randomly into 3 groups, 20 cases in each. Group I, where local vasopressin was used, group II, where OA was used, and group III (the control group), where no specific medication was used and only free Saline was injected locally.Results: The overall results showed that OA group had significantly less operative time and less blood loss compared to control group. However, when compared to cases in group I, operative time and blood loss were significantly higher. Postoperative haemoglobin levels were significantly lower in group III compared to groups I (P = 0.039) and II (P = 0.044). Blood transfusion was indicated in 9 cases among group III, while only one case needed blood transfusion in group II, and no cases in group I.Conclusions: The use of local intra-myometrial OA is an option for reducing blood loss during myomectomy, but still efficacy is less than local vasopressin. This may be attributed to the low concentrations used, and to the less potency of OA as a vasoconstrictor agent.

SummaryIntroduction.Epidural analgesia (EA) is widely used as labor analgesia. It has been reported that EA can slow down the course of labor and increase the risk of operative vaginal delivery. Slower course of labor can lead to an increased risk of abnormal fetal heart rate (FHR). Some studies have also demonstrated an increase in occiput posterior position of the fetal head at delivery if EA is used. It represents a mechanism that may contribute to the lower rate of spontaneous vaginal delivery.Aim of study. To evaluate the impact of EA on the length of labor and the rate of operative vaginal delivery, and to determine whether EA increases the rate of occiput posterior of the fetal head at deliveryMaterial and methods. We carried out a retrospective case-control study based on clinical records from parturients admitted to Riga Maternity Hospital in 2013. Parturients were divided into two groups: case group comprised parturients who had EA, while parturients of control group did not have EA. Groups were further subdivided into primiparas and multiparas and comparisons were made according to parity. We excluded parturients who had obstructed labor, pathological labor, induction of the labor, history of C-section and significant anomaly of the fetus.Results. A total of 832 parturients were included in the study, 304 in EA group (220 primiparas and 84 multiparas) and 528 in control group (257 primiparas and 271 multiparas). Primiparas of EA group had longer latent phase of the first stage of labor in comparison to primiparas of control group (p=0.001), while multiparas of EA group had longer first stage (p=0.031) of labor and longer latent phase of labor (p<0.001) than their respective controls. Vacuum extraction was used in 1.27% of all deliveries with EA. Moreover, vacuum extraction was used only in primiparas an there was no statistically significant difference between EA group primiparas and control group primiparas (1.7% vs. 1.2%, p=0.593). EA did not increase the rate of occiput posterior positon of fetal head. However, primiparas with EA and occiput posterior were more likely to have an abnormal FHR tracing in comparison to primiparas with EA and without occiput posterior position of fetal head (40% vs. 9.8%, p=0.029; RR=4.09, 95% CI 1.3-12.9). There was no statistically significant link between occiput posterior position and abnormal FHR tracing in control group primiparas.Conclusion. EA does not increase the likelihood of operative vaginal delivery. However, parturients with EA have longer latent phase of the first stage of labor. Risk for occiput posterior at delivery is not increased in labor with EA. However, the risk for abnormal FHR among primiparas who receive EA is increased in case of occiput posterior position of the fetal head.

Quantitative Ultrastructure

It is anticipated that Japanese quail /Coturnix coturnix japonica/ will provide animal proteins in long term space flights. Consequently this species of birds is of research interest of international space program INTERCOSMOS. In the year 1987 we reported on an experiment /2/ in which the effect of chronic acceleration of 2 G hypergravitation, the hypodynamy and the simultaneous effect of chronic acceleration and the location in the centre of the turntable of the centrifuge on the protein fractions in skeletal muscles was studied. The ultrastructure of the heart muscle was now in this experiments examined as well.Japanese quail cockerels, aged 48 days were exposed to 2 G hypergravitation /group IV/ in a 6,4 m diameter centrifuge, to hypodynamy /group III/ and their combination /group V/, respectively for 6 days / Fig.1/. The hypodynamy in group III was achieved by suspending the birds in jackets without contact the floor. The group II was located in the centre ofthe turntable of the centrifuge. The control group I. was kept under normal conditions. The quantitative ultrastructure of myocard was evaluated by the methods of Weibel/3/ - this enables to determine the number, relative size and volume of mitochondria volume of single mitochondria, defficiency of mitochondrial cristae and volume of myofibrils.

The article presents the comparative analysis of the state of the cervix in women with endometrial polyps and micropolyps. Patients and methods. The study involved 130 patients aged 18-35 years: 70 patients with endometrial polyps (group I), 30 patients with micropolyps (group II) and 30 patients of the control group (group III). Results. According to the anamnesis of women in the I group were significantly more frequent diseases of the cervix, which corrected physical surgery methods, in particular cryodestruction. In group II, the representatives of these indicators were similar to healthy. Normal colposcopic picture met significantly less frequently in patients and I, and II group. The differences in the incidence of HPV high oncogenic risk in all groups were not statistically significant. Conclusion. Destructive methods used in the detection of any changes in the cervix are often overly aggressive, form scars and contributing to inflamaciones process. In the chain of events leading to the formation of PE, cervical pathology and its correction can take the basic place.

The present study was conducted to investigate the efficacy of Ovsynch and Ovsynch plus protocol in postpartum (day 60) Sahiwal cows (n=18). Animals were randomly divided into three equal groups, viz., Ovsynch group Ovsynch plus group and Control group. Animals of group I (n = 6) were treated with traditional Ovsynch protocol. The animals (n = 6) of group II were treated with Ovsynch plus protocol which consisted of an initial intramuscular injection of eCG (Folligon) @ 250 IU on day 60 postpartum followed 3 days later by GPG (Ovsynch) protocol. In group-III Control, no treatment was given to animals (n = 6). Treated animals were inseminated at a fixed time between 14 and 20 hrs after second GnRH injection, irrespective of estrus detection. Blood samples were collected from each animal on days 50 and 60 postpartum to determine the status of cyclicity in animals based on serum concentrations of progesterone (P4). A third blood sample was collected on the day of prostaglandin treatment to determine the response of first GnRH injection. Four animals each were cyclic, and two were acyclic in both treatment groups. Four animals each responded to first GnRH treatment in both treatment groups. Similarly, two animals each got conceived giving conception rate of 50% (2/4) in each treatment. In the control group, one out of 6 animals got conceived yielding 16.66 % conception rate (1/6) during the study period. It may be thus concluded that Ovsynch and Ovsynch plus protocol may be used during the early postpartum period to improve the reproductive efficiency in postpartum Sahiwal cows.

BACKGROUND: The increased strength of zirconia has resulted in its widespread application in clinical dentistry. Nevertheless, the fracture of veneering porcelains remains one of the key reasons of failure. OBJECTIVE: The objective of this study was to compare and analyze the influence of surface conditioning methods on the core-veneer bond strength of zirconia restorations. METHODS: Thirty specimens of zirconia core with sizes 10 × 5 × 5 mm were layered with porcelain of sizes 5 × 3 × 3 mm. On the basis of different surface conditioning methods, four groups were made: Group I: abrasion with airborne alumina particles of 110 μm size, Group II: sandblasting with silica coated alumina particles of 50 μm in size, Group III (modified group): alteration with a coating of zirconia powder prior to sintering, and Group IV (control group): metal core specimens. The shear force of all specimens was tested using a universal testing machine with a 0.5 mm/min crosshead speed. One-way analysis of variance (ANOVA) and Tukey’s post hoc pair wise comparison (p= 0.05) were performed to analyze the shear bond strength. A scanning electron microscope was used to assess the fractured specimens. RESULTS: A statistically significant difference was noted between the groups. The mean value of shear bond strength was 40.25 MPa for Group I, 41.93 MPa for Group II, 48.08 MPa for Group III and 47.01 MPa for Group IV. CONCLUSIONS: The modified zirconia group and control group demonstrated a significantly higher mean bond strength than that of Group I, where airborne particle abrasion was used. The scanning electron microscope showed that cohesive fracture in the porcelain veneers was the main problem of failure in altered zirconia. The modified zirconia specimens in Group III demonstrated significantly improved values of shear bond strength.

Intraperitoneal injection of ferric nitrilotriacetate (Fe-NTA) to rats and mice results in iron-induced free radical injury and cancer in kidneys. This study was designed to investigate the effect of catechin, a bioflavonoid with antioxidant potential, on Fe-NTA-induced nephrotoxicity in rats. Four groups were employed in the present study. Group I served as control group, Group II animals received Fe-NTA (8 mg iron/kg body weight i.p.), Group III animals were given 40 mg/kg catechin p.o. twice a day for 4 days and on the 5th day Fe-NTA was challenged, and Group IV animals received catechin alone for 4 days. Renal function was assessed by measuring plasma creatinine and blood urea nitrogen. The oxidative stress was measured by renal malondialdehyde levels, reduced glutathione levels and by enzymatic activity of catalase, glutathione reductase and superoxide dismutase. One hour after a single intraperitoneal (i.p.) injection of Fe-NTA (8 mg iron/kg), a marked deterioration of renal architecture, renal function and severe oxidative stress was observed. Pretreatment of animals with catechin markedly attenuated renal dysfunction, reduced elevated thiobarbituric acid reacting substances (TBARS), restored the depleted renal antioxidant enzymes and normalized the renal morphological alterations. These results clearly demonstrate the role of oxidative stress and its relation to renal dysfunction, and suggest a protective effect of catechin on Fe-NTA-induced nephrotoxicity in rats.

Irisin is a new myokine that is suspected to influence metabolic syndrome (MetS). However, there is a great controversy with respect to its level in cases of MetS and its correlation with different metabolic parameters. The present study assesses irisin levels in MetS patients and studies its relationship to metabolic and liver functions to evaluate the possible role of the liver in regulation of this level. Sixty subjects were included in this experiment, who were divided into 3 groups: group I (normal control), group II (MetS patients with normal liver enzymes), and group III (MetS with elevated liver enzymes and fatty liver disease). Serum irisin levels showed significant increases in groups II and III compared with group I, and significant increases in group III compared with group II. Also, irisin levels were positively correlated with body mass index, serum triglycerides, homeostatic model assessment of insulin resistance index (HOMA-IR), and liver enzymes. We concluded that serum irisin levels increased in patients with MetS, especially those with elevated liver enzymes, and had a positive correlation with parameters of lipid metabolism and glucose homeostasis with the possibility of hepatic clearance to irisin.

Pyrethroid cyhalothrin (PC) is an insecticide that is used worldwide for pest control in agriculture and household use. Samoa extract (SE) is a potent antioxidant protecting cells from oxidative stress. The present study investigates the protective and therapeutic effect of SE on PC-induced changes in sperm quality in male rats. Fifty adult male albino rats were divided into five groups: group I: served as control; group II: received PC i.p. only (6.2 mg/kg b.wt.); group III: received SE only (100 mg/kg b.wt., p.o.) for eight weeks; group IV: received SE as a protective agent daily for eight weeks, then followed by the administration of PC (i.p.) three times a week for two weeks; group V: exposed to PC (i.p.) three times a week for two weeks, then treated with the SE daily for 8 weeks. Results showed that PC caused markedly impaired sperm quality (a count, viability, motility, and abnormality). Compared to PC-treated animals, SE in the protective group markedly restored the alteration of sperm indices. However, SE in the curative group was found to be less effective in restoring PC-induced alterations. In conclusion, the data of this study revealed that the SE as a protective agent is more effective than as a therapeutic agent. Keywords: Samoa; Pyrethroid; Sperm quality; Rat

Objective This study aimed to evaluate the impact of the dietary supplement of Moringa oleifera leaves (MOL) on semen quality and characteristics in rabbits. Methods Eighteen (n=18) breeding bucks of New Zealand white, of similar age group, were used for the study. Three feeding regimes, (i) 100% commercial rabbit pellets (CRP)-Group I (ii) 90% CRP + 10% fresh MOL on a dry matter (DM) basis – Group II and (iii) 80% CRP + 20% fresh MOL on a DM basis – Group III, were adopted and the trial continued for 21 days. After adaptation to the diet, semen was collected from each buck and subjected to evaluation using a computer-assisted semen analyser. Results In Group III, the sperm count, normal sperm morphology, and sperm motility increased (52.0%) in comparison with the control (Group I; 50.1%). The inclusion of 20% Moringa oliefera in the diet (Group III) caused a significant increase (P<0.05) in semen concentration (Control =136.2 M/mL; Group III=297.2 M/mL). There was no significant difference (P>0.05) in sperm motility and semen volume among the groups. Conclusion The results suggest that supplementing commercial rabbit pellets with 20% fresh Moringa oliefera leaves on a DM basis can improve the quality and characteristics of semen in breeding bucks.
