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.

Morbidly Adherent Placenta in the First Trimester with Consecutive Hysterectomy.

Background Morbidly adherent placenta (MAP) represents a risk factor for a maternal adverse outcome and its incidence continues to rise following the increasing rate of caesarean deliveries. The detection of a pathology of placental adherence in the first trimester is challenging. Transvaginal ultrasound represents (TVUS) a reliable tool for accurate and timely diagnosis. Case We report on a case of MAP in a pregnant woman at 10 weeks of gestation with two prior caesarean deliveries. She presented with abdominal pain and hematometra. The first trimester diagnosis was made with TVUS and confirmed with magnetic resonance imaging. The patient required an urgent hysterectomy. Conclusion Antenatal care in the first trimester in women with a previous cesarean delivery should include a detailed examination of the placenta with TVUS.

Non-phosphorylated Tyr-1248 form of human epidermal growth factor receptor 2 (HER2) predicts resistance to trastuzumab therapy and poor disease-free survival of HER2-positive breast cancer patients.

AIM: To determine the predictive value of phosphorylated human epidermal growth factor receptor 2 (pHER2Y1248) status in breast cancer (BC) patients undergoing trastuzumab-based adjuvant therapy. METHODS: Immunohistochemical status of pHER2Y1248, EGFR/HER1, HER3, and HER4 was determined in 124 consecutive HER2-positive BC patients (median age [range]=57 years [49.0-64.0]) treated at the University Hospital for Tumors, Zagreb, between 2008 and 2011. The median follow-up was 84 months (60.0-84.0). Prognostic factors of disease free survival (DFS) rate were evaluated with Kaplan-Meier/log-rank test and Cox regression analysis. RESULTS: pHER2Y1248, HER1, HER3, and HER4 were expressed in 66.1%, 9.7%, 70.2%, and 71.0% of patients, respectively. Disease progression (DP) was observed in 17.1% of pHER2Y1248-positive and 47.6% of pHER2Y1248-negative BCs (P=0.001). Kaplan-Meier analysis showed a worse five-year DFS in pHER2Y1248-negative patients who were older than 60 years (P<0.001) and had positive lymph node status (P<0.001); tumor size >2.0 cm (P<0.001); higher histological grade (P<0.001); HER2E intrinsic subtype (P<0.001), negative hormone receptors (P<0.001); negative HER1 status (P<0.001), positive HER3 (P=0.002); and/or positive HER4 (P=0.002) status. The only negative prognostic factor for five-year DFS in multivariate Cox regression analysis was pHER2Y1248-negative (hazard ratio [HR] 3.6, 95% confidence interval [CI] 1.8-7.2, P<0.001) and lymph node-positive status (HR 3.6, 95% CI 1.3-9.8, P=0.014). CONCLUSION: pHER2Y1248 predicts sensitivity to trastuzumab and a better five-year DFS regardless of any other prognostic parameter. In HER2-positive BC patients. Non-phosphorylated HER2Y1248 is a strong predictor of trastuzumab resistance and a poor DFS.

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.

Perimortem Cesarean Section in a Patient with Intrapartum Cardiorespiratory Arrest Due to a Massive Amniotic Fluid Embolism.

We report and discuss the case of a 29-year-old tercigravida with intrapartum cardiorespiratory arrest due to a massive amniotic fluid embolism and disseminated intravascular coagulopathy. Perimortem caesarean section with B-Lynch compression uterine suture with simultaneous fetal and maternal resuscitation were performed with a favorable outcome for both the mother and the child.

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.

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.

The association of the decline in glomerular filtration rate with aggressive endometrial cancers.

PURPOSE: Most site-specific cancer incidence is increased with the decrease of glomerular filtration rate (GFR). We analyzed endometrial cancers depending on different type, staging, and histology grades. We hypothesized that patients with lower GFR levels have an increased risk for higher staging and histology grades of endometrial cancers. METHODS: Patients were divided into two subgroups regarding GFR; the first group with GFR < 60 ml/min and the second group with GFR > 60 ml/min and regarding different histology grades and cancer stages. Cancers were also divided by stages (1-4). Patients were followed up during 1 year through regular controls in the outpatient clinic and during that time cancer recurrence was recorded. RESULTS: GFR was the strongest predictor for higher cancer histology grade and higher cancer staging. Patients with reduced GFR had OR for higher histology grade and higher staging of 1.06 and 1.06. Traditional risk factors for endometrial cancer development were not associated with higher histology grade or higher cancer staging. CONCLUSION: Higher staging and histology grades in patients with endometrial cancers are associated with reduced GFR. Patients with mild-to-moderate CKD had significantly higher number of cancers with higher histology grades and higher stages than patients with mild or normal GFR category. Decline in GFR was independently associated with more aggressive cancers without other well-known risk factors for endometrial cancer development like age, menopause, diabetes, and obesity.

PRIMARY HODGKIN'S LYMPHOMA OF THE BREAST INITIALLY TREATED BY SURGICAL EXCISION AND AXILLARY DISSECTION.

Primary breast lymphoma accounts for 0.04%-0.5% of all breast malignancies. Primary non-Hodgkin's lymphomas of the breast are extremely rare and represent approximately 0.38%-0.7% of all cases. Epstein-Barr virus (EBV) has been postulated to play an important role in the pathogenesis of Hodgkin's lymphoma. We present a case of EBV-positive primary Hodgkin's lymphoma of the breast. Although there is no sufficient data on this challenging diagnosis, it is known that it could be misdiagnosed with inflammatory breast carcinoma. A crucial part of the proper histopathologic diagnosis is immunohistochemistry. Different modalities of treatment include operative procedure, chemotherapy and radiotherapy. Recent studies suggest chemotherapy and radiotherapy to be initial treatment for patients with primary breast lymphomas.

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.
