Obstetrics injuries during shoulder dystocia in a tertiary perinatal center.

OBJECTIVES: This study will present our results in management of fetal shoulder dystocia with special consideration of maternal and neonatal outcome. STUDY DESIGN: A retrospective study was performed at a university tertiary perinatal center. The study included data of singleton vaginal term deliveries in the period of 15 years (2006-2020). Analized informations include: obstetrics maternal and neonatal data and outcomes. RESULTS: This period included 45,687 deliveries with diagnosed shoulder dystocia in 254 (0.7 %) cases in vaginal deliveries. Most of the deliveries were spontaneous births 69.7 %, induced deliveries 30.3 %, 47.2 % primiparas and preexisting or gestational diabetes in 21.7 %. The delivery was managed by vacuum extraction in 13.8 %, mediolateral episiotomy in 48.0 % of births, most of the shoulder dystocia were unilateral anterior, while only two cases were diagnosed as more difficult bilateral and 5 cases were recurrent. 87.4 % cases were resolved by McRobert's maneuver, 7.8 % by Barnum's 3.9 % by Wood's maneuver and one case was managed by Menticoglou and by Bourgoise-Siegemundin maneuver. 4.3 % injuries were classified as OASIS of III/IV degree, early postpartum hemorrhage due in 1.6 %. 54.3 % of newborns were male sex, 61.0 % of newborns had birth weight of above 4000 g (mean 4071 g). Maximal Apgar scores were atributed to 92.5 % in first and to 97.2 % in fifth minute, one case that requaired resuscitation. Clavicle fracture was found in 9.5 %, humerus fracture in 0.4 %, transient form of Duchenne Erb obstetrics brachial palsy was diagnosed in only in 7.5 % newborns, while we have not found any case of permanent brachial palsy. CONCLUSIONS: Our results confirmed that strategy of prompt identification of shoulder dystocia accompanied by cessation of axial fetal head traction decrease the risk of brachial plexus strain, injury or tear, while performance of exact obstetrical maneuvers resulted in decanceration of fetal shoulders without permanent obstetrics brachial palsy or cerebral morbidity. We think that our good results corelate with our opinion that the performance of external obstetrical manoeuvres should be done without one minute postpone since efforts should be put in sooner shoulder liberation decreasing the time of fetal hypoxia.

Mothers' Anxiety to Aggravated Acute Fear of Earthquakes in the City of Zagreb in the COVID-19 Pandemic.

BACKGROUND: Here we present the results of a psychometric investigation on current fear of COVID-19 infection aggravated by the earthquake-induced stress in the group of puerperal women. SUBJECTS AND METHODS: A group of 16 hospitalized puerperal women that gave birth at Clinical Hospital Sveti Duh in Zagreb, Department of Obstetrics and Gynecology were enrolled in retrospective clinical investigation. All the patients delivered during COVID-19 pandemic and experienced devastating earthquake on March 22nd. The women were interviewed on the exact day of the earthquake, 4 hours after the main hit and 6 months after that during second pandemic wave on October of the same year. Women were also questioned about the breastfeeding. The participants provided written informed consent and were interviewed using Generalized Anxiety Disorder 7-item (GAD-7) scale for evaluation of generalized anxiety disorder. RESULTS: Minimal level of anxiety after the earthquake was shown for 10 mothers with 6 of them having the highest level 4. Mild anxiety was proven for 3 patients, 2 exhibited moderate anxiety with one puerperal women with severe anxiety. One could say that 37.5% of enrolled patients exhibited some degree of anxiety after the earthquake (scoring >5). At second time point during COVID-19 pandemic 13 participants had minimal anxiety score, 2 had mild, while 1 participant had moderate score evaluated by GAD-7 scale (18.8%). At the time of the earthquake 13 participants were breastfeeding (81.3%), while 3 were not due to the personal reasons. 6 months after the earthquake only 7 mothers were breastfeeding (43.8%), while 9 of the participants were feeding their children with adapted milk (56%). Main reason for breastfeeding discontinuation was the stop of milk secretion in the 6 months period after the delivery. CONCLUSIONS: To our knowledge, our study is the only national study dealing with mental health problems in a population of puerperal and breastfeeding mothers in a challenging time of COVID-19 pandemic aggravated by devastating earthquake.

Transvaginally surgically treatment of early postpartum hemorrhage caused by lower uterine segment atony.

OBJECTIVES: Prove the success of transvaginal hemostatic procedures in treatment of the early postpartum hemorrhage caused by lower uterine segment atony. METHODS: We have conducted a retrospective, clinical study during a 10-year period (2010-2019) in our institution that is tertiary perinatal university center. RESULTS: This particular study enrolled total number of 29,543 deliveries with 215 cases of early postpartum hemorrhage (0.72%). Lower uterine segment atony was diagnosed in 44 cases (29.93%) in all uterine atony cases of early postpartum hemorrhage. Hemostatic ligation procedures according to authors: Losickaja in two cases, Hebisch-Huch in 13 cases, Habek in seven cases, Hebisch-Huch + Losickaja in 10 cases. According to our results, hemostatic ligation procedures alone (32 cases; 72.72%) or combined with gauze or ballon tamponade (five cases, 11.36%), have shown to be highly effective in 37 cases (84.09%). CONCLUSIONS: Lower uterine segment atony should definitely be identified and understood as a clinical entity. Transvaginal hemostatic approach for surgical treatment of lower uterine segment atony is accessible, minimally invasive, feasible, successful and lifesaving. All of the above-mentioned methods are of great importance in the prevention and treatment of obstetric shock, multiorgan failure, postpartum hysterectomy and finally vital for fertility preservation.

Torquated large ovarian lymphoma as a cause of acute abdomen: a case report of diffuse large B-cell ovarian lymphoma with a germinal center B-cell-like phenotype.

BACKGROUND: Ovarian lymphoma is a rare neoplasm and most commonly represents secondary ovarian involvement in overt systemic disease, usually of the non-Hodgkin's type. AIM: To report a case of acute abdomen caused by torquated large ovarian lymphoma. CASE REPORT: We report the case of 65-year-old patient admitted to our hospital with signs and symptoms of acute abdomen. Findings were suggestive of left ovary torsion due to the neoplasm. After detorsion, mobilization, and adhesiolysis, a bilateral adnexectomy was performed. Histopathological and immunohistochemical analysis of the left ovarian tumor was performed and diagnosis of diffuse large B­cell lymphoma (DLBCL) with a GCB (germinal center B­cell-like) phenotype was made. Additional bone marrow biopsy and imaging techniques excluded other sites of involvement, confirming diagnosis of primary ovarian DLBCL. CONCLUSION: The prognosis of ovarian lymphomas may be poorer than for other lymphomas because of late diagnosis. The best treatment option appears to be systemic chemotherapy.

IS THERE A RELATIONSHIP BETWEEN COMPLICATIONS OF EARLY PREGNANCY AND BIOMETEOROLOGICAL FORECAST?

The aim of our study was to connect the possible complications of early pregnancy (miscarriage and symptomatic ectopic pregnancy) up to the 12th week of gestation with biometeorological conditions while assuming a greater number of incidents with an unfavorable biometeorological forecast. We performed a retrospective observational study using medical data of a single medical center of Department of Gynecology and Obstetrics, Sveti Duh University Hospital and meteorological data from the Croatian Meteorological and Hydrometeorological Service in Zagreb. We tracked the number of visits to the gynecology and obstetrics emergency unit on a daily basis during 2017. Days with five or more visits were selected and underwent further analysis, during which the number of miscarriages and symptomatic ectopic pregnancies was noted. The information from the biometeorological forecast was then extracted and added to the database. Our results did not show a statistically significant difference between the groups determined by biometeorological forecast in the number of spontaneous abortions or ectopic pregnancy. Also, statistically significant results did not follow the expected trend of the increasing number of complications related to worse biometeorological forecast, or vice versa, a decreased number of complications with better forecast. Our single-center retrospective analysis of emergency unit visits related to weather conditions did not show a connection between the complications of early pregnancy and biometeorological conditions. However, different results could emerge in future studies. Considering the large and high-quality database collected for this study, efforts in researching the connection between other gynecologic pathologies and weather conditions will be feasible.

Effects of lateral episiotomy on the emergence of urinary incontinence during the first postpartum year in primiparas: prospective cohort study.

AIM OF THE STUDY: Lateral episiotomy is a widely used procedure, although it is rarely mentioned in the literature and its effects on the pelvic floor are largely unexplored. The purpose of this study is to evaluate the impact of lateral episiotomy on the incidence of urinary incontinence (UI) after vaginal delivery in primiparas. MATERIAL AND METHODS: The study design is a prospective cohort study. The primiparas were divided into two groups. The first group consisted of women who gave birth with lateral episiotomy, while the second group included women who gave birth with an intact perineum or with perineal tears of first and second degree. Assessments of UI were performed at 5 and 8 months after childbirth using the International Consultation on Incontinence Questionnaire - Short Form (ICIQ-SF) questionnaire followed by the stress test. RESULTS: The results revealed no significant differences (p > 0.05) in emergence of stress urinary incontinence (SUI) between the groups at the two time points. There were no statistically significant differences in overall rate of UI, urge urinary incontinence (UUI), or mixed urinary incontinence according to the ICIQ-SF questionnaire. The overall incontinence rate on the first examination was 24% in the episiotomy group and 36% in the perineal laceration group, although the difference was not statistically significant (p = 0.064). On the second examination, rates were similar and without a statistically significant difference. CONCLUSIONS: Lateral episiotomy has a neutral effect on the onset of UI in primiparous women in the first year after delivery.

Modified Stark's (Misgav Ladach) caesarean section: 15 - year experience of the own techniques of caesarean section.

OBJECTIVE: A 15-year-experience of the personal modification of Misgav Ladach (ML) caesarean section in relation to the Dörffler method. STUDY DESIGN: A retrospective clinical randomized observational study included 822 transperitoneal cesarean sections: 557 were performed via modified ML (without bladder catheterization, small transverse fascial incision with muscular stretching and non-preparation of vesicouterine plica) vs. 265 Dörffler (Pfannenstiel - Kerr) method. RESULTS: Perioperative and postoperative complications were significantly more frequent in the Dörffler method (p < 0.0005) (perioperative hemorrhage, more frequent adhesions, plastic peritonitis in repeated caesarean sections, as well as two bladder lesions). Postoperative febrility, dehiscence and wound seroma were more frequent in the first study group (p < 0.0005). More frequent paralytic ileus, uroinfections and bladder atony, which we did not observe in our own technique (p < 0.0005). The use of antibiotics and analgesics was prolonged until the fifth postoperative day in the first group compared to the second group where it was reduced to only 10 % on the second day (p < 0.0005). Also, the incidence of anemia and the need for blood transfusions were higher in the first study group, as well as the need for revision behind caesarean section and two hysterectomies due to massive postoperative intraperitoneal and retroperitoneal bleeding (p < 0.0005). CONCLUSION: Our fifteen-year study highlighted the importance of our own published modified ML caesarean section in minimizing technique of surgery and the reduction of perioperative morbidity and significantly faster recovery of operated patients in the current era of enormous caesarean section increase.

Modified Ritgen Maneuver in Perineal Protection - Sixty-Year Experience.

The aim is to present the 60-year experience in modified Ritgen maneuver according to perineal injuries. This retrospective clinical observational study (1950-2010) analyzed the impact of modified Ritgen maneuver delivery technique (controlled fetal head deflexion with left hand and synchronous reduction of perineal strain with extended right hand thumb along the right side of the vulva and perineum without pushing) on peripartum perineal tears at the Maternity Ward, Bjelovar General Hospital in Bjelovar, Croatia, divided into five-year intervals. The rate of perineal tear in general was less than 5% until 2000. The rate of perineal tear grade I was very low until 1995, then increased to 8.6% in 2010, yet never exceeding 10%. The rate of perineal tear grade II never exceeded 2%, whereas perineal tear grade III was a sporadic event never exceeding 0.4% of the study material with a single case of grade IV tear. The rate of intact perineum in vaginal deliveries without episiotomy ranged from 96.2% to 100% in the 1950-1960 period, with a decrease to 46% in 2010. The study revealed the modification of Ritgen maneuver described to have resulted in significant re-duction of all grades of perineal tear over decades.

Acute Abdomen Syndrome Due To Spontaneous Intraperitoneal Bladder Rupture Following Vaginal Delivery.

We report a rare case of spontaneous intraperitoneal bladder rupture following normal vaginal delivery without concomitant uterine rupture. Key diagnostic clinical features were acute renal failure, new-onset ascites and bowel ileus with urosepsis. Laparotomy and bladder repair with omentum patch were performed with no adverse outcome reported.

Systemically available bone morphogenetic protein two and seven affect bone metabolism.

PURPOSE: Bone morphogenetic protein (BMP)-2 and -7 are used in patients with long-bone fractures, nonunions and spinal fusions. It is unknown whether their potential systemic bioavailability following local bone administration might affect skeletal metabolism. To answer this question, we examined effects of systemically administered BMP-2 and -7 on bone in a newly developed rat model with a low level of calciotropic hormones. METHODS: Removal of thyroid and parathyroid glands (TPTx) in rats resulted in a decreased level of calciotropic hormones and subsequent bone loss assessed by micro computed tomography (micro-CT) and measurement of serum bone formation and resorption markers, including osteocalcin, C-telopeptide, osteoprotegerin and receptor activator of nuclear factor kappa-B ligand. Results were complemented with in vitro studies on osteoblast and osteoclast activity by both BMP-2 and -7. The doses used were calculated from published pharmacodynamic studies and bioavailability results from preclinical BMP-2 and -7 studies. RESULTS: TPTx resulted in bone loss, which was restored by systemic administration of 10-70 µg/kg of BMP-2 and 10-250 µg/kg of BMP-7. BMP-2 showed a higher capacity for enhancing trabecular microarchitecture, whereas BMP-7 augmented trabecular thickness. In vitro experiments revealed that BMP-2 and -7 when uncoupled increased the number and activity of both osteoblasts and osteoclasts. CONCLUSIONS: Surprisingly, both BMP-2 and -7 showed an increased bone volume in an in vivo environment of low calciotropic hormones. Locally administered BMP-2 and -7 from bone devices might become partially available in circulation but will not mediate systemic bone loss.

Potential beneficial role of sevelamer hydrochloride in diabetic retinopathy.

Patients with chronic kidney disease (CKD) experience co-morbid illnesses, including cardiovascular disease and retinopathy. Sevelamer hydrochloride (Renagel®); a non-calcium phosphate binder reduces coronary artery and aortic calcification as compared to calcium containing phosphate binders and additionally effects inflammatory biomarkers such as C-reactive protein (CRP), and lowers LDL cholesterol in patients with CKD. Since retinopathy is proven to be associated with increased coronary calcification, shared pathophysiological processes may contribute to both microvascular and macrovascular disease. We here suggest three different mechanisms of possible sevelamer's influence on the retinopathy: (1) by direct effect on the microvasculature through lowering CRP and LDL, involved in endothelial dysfunction and atherogenesis, (2) indirectly by attenuation of vascular calcification of aorta and carotid internal artery, it reduces ischaemia and improves circulation in the opthalmic artery and hence postponing retinopathy, (3) through hypertension by reducing atherosclerosis and calcification of carotid arteries, sevelamer decreases stiffness and intima-media wall thickness, therefore lowering blood pressure, which is well known to increase progression of diabetic retinopathy. So far no studies have yet been published on the direct influence of sevelamer on the retinopathy which we believe has good theoretical background. With its combined macrovascular and microvascular effect, sevelamer could potentially postpone and/or decrease retinopathy in diabetic patients with hypertension, and that are on hemodialysis or even predialysis patients.

The antimetastatic effect of macrophages restored by indomethacin: concomitant tumor immunity model.

The role of macrophages acting as immunologic antitumor effectors and promoters of tumor growth are poorly understood as yet. We investigated the role of macrophage in model of concomitant immunity (CI), a phenomenon of secondary tumor rejection during the primary tumor growth. It has been shown that the period of CI weakening can coincide with appearance of tumor metastases. We used mammary carcinoma (MC) artificial lung metastases to evaluate the influence of macrophages from various period of CI on the development of metastases in mice. Our results indicated that macrophages are responsible for the late period of CI weakening and suppression. To investigate weather prostaglandins can mediate suppressive effect of macrophages we used experiments with indomethacin and we found that inhibition of prostaglandin E2 synthesis by indomethacin restored antimetastatic effect of concomitant immune macrophages.

Is hyperthyroidism underestimated in pregnancy and misdiagnosed as hyperemesis gravidarum?

Thyroid changes are considered to be normal events that happen as a large maternal multiorganic adjustment to pregnancy. However, hyperthyroidism occurs in pregnancy with clinical presentation similar to hyperemesis gravidarum (HG) and pregnancy itself. Moreover, 10% of women with HG will continue to have symptoms throughout the pregnancy suggesting that the underlying cause might not be elevation of human chorionic gonadotropin in the first trimester. Variable frequency of both hyperthyroidism and HG worldwide might suggest the puzzlement of inclusion criteria for both diagnoses enhanced by the alternation of thyroid hormone levels assessed in normal pregnancy. Increased number of hyperthyroidism among women population without the expected rise in gestational hyperthyroidism encouraged us for creating the hypotheses that hyperthyroidism could be underestimated in normal pregnancy and even misdiagnosed as HG. This hypothesis, if confirmed, might have beneficial clinical implications, such as better detection of hyperthyroidism in pregnancies, application of therapy when needed with the reduction of maternal or fetal consequences.

Pattern and prenatal diagnosis of skeletal dysplasias in Qatar population.

OBJECTIVE: To determine the pattern of skeletal dysplasias in Qatar population and to assess the accuracy of prenatal diagnosis and prognosis. METHODS: This was a retrospective descriptive study of 30 women with high risk for skeletal dysplasias. The recruited women were submitted to clinical assessment, ultrasound scanning using 2-dimensional, 3-dimensional/4-dimensional and colour Doppler technique with possible molecular diagnosis. The findings were compared with the postnatal or postmortem assessments. Final diagnosis was based on clinical examination, skeletal survey, autopsy and molecular testing as deemed necessary. RESULTS: Thirty cases of skeletal dysplasia were antenatally diagnosed over 4-year period with family history in few cases. Among many entities thanatophoric dysplasia showed largest prevalence [7(23%)]. Prenatal diagnosis was accurate in 76% of foetuses while the first indicator of abnormality was a suspected anomaly found during routine ultrasound assessment in most cases [17(56%)]. Prediction of lethality based on ultrasound findings was 100% accurate. CONCLUSIONS: This study confirmed the possibility of good prenatal diagnosis of skeletal dysplasias present among Qatar population. Diagnosis based on ultrasound assessment will improve by adding molecular techniques with positive impact on prenatal care.
