Assessing Symptomatic Hypocalcemia Risk After Total Thyroidectomy: A Prospective Study.

Introduction The most common postoperative complication of total thyroidectomy is hypocalcemia, usually monitored using serum parathyroid hormone and calcium values. Objective To identify the most accurate predictors of hypocalcemia, construct a risk assesment algorithm and analyze the impact of using several calcium correction formulas in practice. Methods A prospective, single-center, non-randomized longitudinal cohort study on 205 patients undergoing total thyroidectomy. Parathyroid hormone, serum, and ionized calcium were sampled post-surgery, with the presence of symptomatic or laboratory-verified asymptomatic hypocalcemia designated as primary outcome measures. Results Parathyroid hormone sampled on the first postoperative day was the most sensitive predictor of symptomatic hypocalcemia development (sensitivity 80.22%, cut-off value ≤2.03 pmol/L). A combination of serum calcium and parathyroid concentration sampled on the first postoperative day predicted the development of hypocalcemia during recovery with the highest sensitivity and specificity (94% sensitivity, cut-off ≤2.1 mmol/L, and 89% specificity, cut-off ≤1.55 pmol/L, respectively). The use of algorithms and correction formulas did not improve the accuracy of predicting symptomatic or asymptomatic hypocalcemia. Conclusions The most sensitive predictor of symptomatic hypocalcemia present on the fifth postoperative day was PTH sampled on the first postoperative day. The need for algorithms and correction formulas is limited.

DILEMMAS ABOUT THE SELECTION OF ANESTHESIA FOR ELECTIVE CESAREAN SECTION IN PREGNANT WOMEN WITH MYOTONIC DYSTROPHY TYPE 2 AND SUSPECTED von WILLEBRAND DISEASE: A CASE REPORT.

With advancement of medicine in the field of diagnostics and treatment of women suffering from certain genetic disorders, more and more women have attained reproductive age and desired fertility. Maintaining pregnancy, as well as bringing it to an end poses a real challenge not only for obstetricians, but also for anesthesiologists involved in the procedure. In our case report, we describe anesthetic management of a female patient suffering from myotonic dystrophy type 2 and suspected von Willebrand's disease, and undergoing elective cesarean section. It is acknowledged that both diseases have their own peculiarities and specificities related to anesthesia and require careful consideration when it comes to selecting it. Bearing in mind the advantages and disadvantages of certain types of anesthesia, we believe that in this case, general anesthesia was a better choice compared to the regional techniques of anesthesia.

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.

PERINATAL ASPECTS OF SARS-CoV-2 INFECTION DURING PREGNANCY: A POTENTIAL CAUSE FOR CONCERN.

Ever since the beginning of COVID-19 pandemic, uncertainty regarding clinical presentation and differences among various subpopulations exist. With more than 209,870,000 confirmed cases and more than 4,400,000 deaths worldwide, we are facing the new era of health crisis which will undoubtedly impair global health, economic and social circumstances. In the past year, numerous genetic mutations which code SARS-CoV-2 proteins led to the occurrence of new viral strains, with higher transmission rates. Apart from the implementation of vaccination, the effect of SARS-CoV-2 on pregnancy outcome and maternal fetal transmission remains an important concern. Although neonates diagnosed with COVID-19 were mostly asymptomatic or presented with mild disease, the effect on early pregnancy is yet to be evident. While positive finding of SARS-CoV-2 RNA in some samples such as amniotic fluid, placental tissue, cord blood and breast milk exists, additional research should confirm its association with transplacental transmission.

OBSTETRIC INJURY OF THE RECTUM WITH INTACT ANAL SPHINCTER - TWO CASE REPORTS.

Background: Injury of the rectum with intact anal sphincter is an extremely rare but very serious complication of vaginal delivery. It is also called a "buttonhole" tear. Case: We present two cases of "buttonhole" tear/injury. Results: In one case, the injury was recognized at the time of delivery and adequately treated. In the other case the injury was not diagnosed on time and the patient was treated for complications on the 6th postpartal day. Conclusion: The consequences for the wellbeing of young mothers with perineal injury can be serious and affect social and sexual aspects of their lives. Adequate surgical treatment and postoperative care assure optimal results and prevent long term complications such as fistulas or fecal incontinence.

RISK ASSESSMENT IN PREGNANCY AMONG WOMEN AGED OVER FORTY.

The objective of this study was to assess the relationship between women's age and risk of pregnancy-related complications. The study was a retrospective cohort analysis of the pregnancy-related complications and outcomes between two age groups of parturient women. Categorical data were expressed as absolute and relative frequencies. Statistical analysis was performed using χ2-test. The incidence of gestational diabetes was higher in the 40-47 age group as compared with the 20-24 age group. The rates of hypertension, preeclampsia, intrahepatic cholestasis of pregnancy and hypothyroidism did not differ between the two groups. The rates of labor induction, oxytocin use, vaginal delivery, and need for episiotomy were higher in younger age group. Dystocia and breech presentation as indications for cesarean section were more common among younger women. According to study results, the risk of gestational diabetes and rates of cesarean delivery increased with advanced maternal age.

UTERINE RUPTURE IN THIRD TRIMESTER OF PREGNANCY FOLLOWING CORNUAL RESECTION DUE TO ECTOPIC PREGNANCY.

Uterine rupture during pregnancy is a critical obstetric complication associated with maternal and fetal mortality and morbidity. The risk is increased in patients with a history of previous uterine surgery including cesarean section, myomectomy, salpingectomy, as well as uterine and placental anomalies and polyhydramnios. It can also occur spontaneously. We present a case of uterine rupture in the early third trimester in a woman who had undergone previous laparoscopic removal of the left fallopian tube due to sactosalpinx and laparotomic removal of left uterine horn due to ectopic pregnancy.

Urinary troponin concentration as a marker of cardiac damage in pregnancies complicated with preeclampsia.

Pregnant women with preeclampsia experience significant hemodynamic changes which lead to an increased myocardial workload. In response to increased demands in pregnancy, the heart muscle responds with ventricular remodeling process which involves cardiac muscle hypertrophy. Opposed to occurrence of eccentric ventricular hypertrophy in normal pregnancy, myocardial remodeling in a form of concentric hypertrophy will occur in pregnant patients with preeclampsia. Increased myocardial workload is manifested by an increased troponin release. As process of troponin degradation continue, filtration of degradation fragment through glomerular membrane occur, raising the possibility of it's detection in urine. Degradation fragments of troponin molecules are estimated to be 20 kDa with preserved immunoreactivity to high-sensitivity assays. Some of the authors suggest that serum levels of cardiac troponin I might be elevated in patients with hypertension, as well as in preeclamptic pregnant women. It is to be expected that evaluation of severity of the myocardial damage in pregnant woman with preeclampsia may be performed by measuring levels of troponin in the urine using high-sensitivity assays. Designing of urine dipstick will help to detect an early phase of myocardial involvement in preeclamptic pregnancies.

Spontaneous Rupture of Venae Gastricae Breves in Pregnancy: Case Report.

INTRODUCTION: Hemiperitoneum caused by venous bleeding from the hilum of the spleen is a rare cause of acute abdomen in the last trimester of pregnancy. MATERIAL AND METHODS: We are presenting a case of a twenty-nine-year-old primipara with the clinical picture of acute abdomen. CASE REPORT: Primipara in the 36th week of pregnancy presented with the clinical picture of acute abdomen with the ultrasound finding of free fluid in the abdominal cavity and foetal bradycardia. Considering the clinical picture of the mother and the risks for the foetus, it was decided to complete the pregnancy with an emergency caesarean section. During the procedure, exploration of the abdominal cavity found the bleeding site from the venae gastricae breves, and a surgeon stopped active bleeding. CONCLUSION: Non-obstetric bleedings are not common in pregnancy, but they are life-threatening both to the mother and the foetus. The exact cause is usually found during the surgical procedure. If a pregnant woman presents with a clinical picture of abdominal pain, and the signs of foetal distress or clinical instability of the mother are also present, an emergency surgical procedure is indicated. In this case, the indication was foetal bradycardia, and the child was born alive by a caesarean section, while an extended surgical procedure saved the mother's life.

INCREASED OASIS INCIDENCE - INDICATOR OF THE QUALITY OF OBSTETRIC CARE?

In the era of new molecular, epigenetic and proteomic discoveries, birth canal injuries seem like outdated discussion. A vast increase in the incidence of obstetric anal sphincter injuries (OASIS) has been recorded in the last two decades despite advantages in modern medicine and new obstetric methods. This increase might be attributed to the new classification of perineal injury but also to the new imaging methods, including endoanal sonography, which earlier identifies injuries that previously were considered to be occult and actually underwent unrecognized, and which should have been recognized immediately postpartum. OASIS are third and fourth degree perineal injuries that occur during delivery. The reported incidence of OASIS varies from 0.1% to 10.9%. It is well known that third and fourth degree perineal injuries occur more often in primiparae, and in cases of macrosomic newborn, dorsoposterior position of fetal head and shoulder dystocia. The protective role of episiotomy is controversial. Birth canal injury during delivery can happen to any parturient woman. It is important for obstetricians to have this in mind at every delivery. Repercussions of OASIS are serious and can persist for life. They include emotional, psychological, social, physical and sexual disturbances. Therefore, it is very important to recognize the risk factors, diagnose the injury on time and treat it properly by a multidisciplinary team. Accordingly, it can be concluded that the increased incidence of OASIS is a result of better recognition of the risk factors, reduced rates of unrecognized sphincter injuries, adoption of the new classification and better postpartum imagining methods for detection of occult injuries.

Auricular acupuncture as effective pain relief after episiotomy: a randomized controlled pilot study.

PURPOSE: Previously, pain treatment following episiotomy has relied on non-steroid anti-inflammatory drugs as analgesics, whose use during breastfeeding remains controversial due of their transfer to the child. METHODS: This was a pilot randomized parallel single-center study aiming to evaluate the effects of auricular acupuncture on pain relief after episiotomy. The primary outcome was reduction of pain intensity using visual analogue scale (VAS) scores during the first three postpartum days. The patients were allocated to either of the groups by using a heads-tails binary result coin toss method and the allocation was not masked. The study was completed after including 60 healthy women that underwent mediolateral episiotomy performed during vaginal delivery, with 29 receiving acupuncture therapy and 31 not receiving acupuncture therapy for pain relief. Oral analgesic therapy was made available per request for all patients. RESULTS: This study showed that subjective experience of pain was significantly reduced in the acupuncture group on the second and third postpartum days (P = 0.004, P = 0.005, P = 0.22). There were no adverse effects of acupuncture noted. CONCLUSIONS: Our findings confirm that auricular acupuncture therapy may be a valuable adjunct to analgesic therapy in patients undergoing episiotomy during vaginal delivery. The results prompt a question whether our current 'best practice' may yet be improved.

PREGNANCY OUTCOME IN GESTATIONAL DIABETES COMPARED TO BODY MASS INDEX.

Gestational diabetes involves disorder of glucose metabolism first diagnosed in pregnancy. Obese women undoubtedly have more often complications in reproductive age, such as fertility difficulties, spontaneous and recurrent miscarriages, premature births, and various obstetric and surgical complications related to the course of pregnancy, delivery and puerperium. Children of obese pregnant women are more likely to develop obesity in childhood and adulthood. We analyzed the outcome of 51 pregnancies in obese pregnant women and 50 pregnant women with normal body mass index. All women in both groups were diagnosed with gestational diabetes by the IADPSG criteria. We analyzed gestational age at delivery and mode of delivery, gestational weight gain, presence of concomitant diagnosis of gestational or chronic hypertension, difference in birth weight, and prevalence of hypertrophic newborns. There was no significant difference in gestational age at pregnancy termination and in the mode of delivery. There was a significant difference in gestational weight gain, number of pregnant women with hypertension, neonatal birth weight and number of hypertrophic children. Based on the data presented, we conclude that obesity is an unfavorable factor for pregnancy outcome. It also influences birth weight and fetal hypertrophy, as well as gestational weight gain.

Incidental Finding Of Hyperreactio Luteinalis during Caesarean Section in Twin Pregnancy.

BACKGROUND: Some benign changes of the ovaries like hyper reaction luteinalis sometimes cannot be differentiated from malignant ones without histological examination. In these cases, surgical intervention sometimes cannot be avoided. Hyperreactio luteinalis is a condition that can occur only in pregnancy. It is characterised by bilateral benign multicystic ovarian enlargement. CASE REPORT: We present a case of misleading intraoperative findings during Cesarean section that ended with ovariectomy. CONCLUSION: During the Caesarean section, some benign masses of the ovaries, like hyper reaction luteinalis, are difficult to differentiate from malignant disease without histological examination, requiring surgical intervention.

Spontaneous Rupture of Internal Iliac Artery in Pregnancy: Case Report.

Rupture of the internal iliac artery is a rare complication in pregnancy that is associated with maternal and fetal morbidity and mortality. We present a case of a 30-year-old primipara admitted to our department in 39th week of gestation after sudden onset of intense abdominal pain. On admission, the patient was pale, tachycardiac, but with normal blood pressure and afebrile. Symptoms of acute abdomen were clear and surgery was indicated. Diagnosis was confirmed during cesarean section. Enlarged gravid uterus compressed the ruptured artery and prevented heavier bleeding. Acute bleeding due to arterial rupture causes severe symptoms, predominantly abdominal pain. Changes in blood count become significant some time after the onset of rupture. As the gravid uterus compressed the arterial rupture, preoperative bleeding was by far less abundant than the bleeding after the baby had been delivered and the size of the uterus decreased. Any cause of acute abdomen during pregnancy (abruption of the placenta, spleen rupture, visceral artery thrombosis) requires urgent surgical treatment, as well as intraoperative and postoperative intensive treatment. Rupture of the internal iliac artery is a rare complication in pregnancy, but has to be considered as a differential diagnosis of abdominal pain.

Third and Fourth Degree Perineal Tear in Four-Year Period at Sestre Milosrdnice University Hospital Center, Zagreb, Croatia.

OBJECTIVES: Obstetric anal sphincter injury (OASIS) includes the third and fourth degree of perineal injury. The risk for OASIS is about 1% of all vaginal deliveries. If not recognised and treated properly, obstetric anal sphincter injury can have serious consequences for reproductive age woman. MATERIAL AND METHODS: We have retrospectively gathered and analysed data on obstetric anal sphincter injury in a four-year period at our department. The control group in this study included vaginal deliveries in 2012. RESULTS: We recorded 0.34% third and fourth degree of perineal injury in all vaginal deliveries, and 87.9% of those patients were primiparae. Episiotomy was performed in 57.6% of all women with obstetric anal sphincter injury. In 30.3% of cases, newborns were large for gestational age. Gestational diabetes was found in 9.1% of OASIS cases, occipitoposterior position was found in 9.1% of cases. Induced labour took place in 39.4%, and oxytocin infusion was applied in 60.6% of OASIS cases. Vacuum extraction was performed in 12.1% of deliveries with OASIS. The average BMI in 3a and 3b injuries was 29.9. In 3c degree it was 28.0, and in the fourth degree, it was 32.1. In 27.0% of OASIS cases due to the extent of the injury surgeon engagement was necessary. When compared with vaginal deliveries in 2012 we found a significant increase in OASIS in primiparas, large for gestational age, occipitoposterior position, induced labour, vacuum extraction and hypertension (P < 0.01). There is also increased incidence of OASIS in episiotomy and oxytocin use group (P < 0.05). CONCLUSION: Low incidence of OASIS in our department is a result of active management of delivery, manual perineal protection and timely episiotomy.

Henoch-Schönlein purpura in the third trimester of pregnancy.

Henoch-Schönlein purpura (HSP) is an IgA-mediated small vessels' vasculitis that affects the skin, intestines and kidneys. Pregnancy has been reported as an exacerbating factor. We present the case of a 24-year-old primigravida with HSP that occurred in the third trimester and lasted up to the end of the successful delivery. She had pruritic maculopapular exanthema on her legs. Biopsy of a cutaneous lesion was performed for histopathologic features and direct immunofluorescence (DIF) for the presence of perivascular IgA deposition. Histopathology of the cutaneous lesion confirmed leukocytoclastic vasculitis. A DIF examination of the skin lesion confirmed deposits of fibrinogen in the small blood vessel walls. Six weeks following delivery, the skin lesions almost completely disappeared. Control laboratory findings were normal. This case of HSP might have been primarily associated with a preceding respiratory infection but this should first be carefully investigated due to a possible severe immunological disease in the patient's background requiring special attention since nephrotic symptoms may occur.

CERVICAL RIPENING BALLOON AS A METHOD OF PREINDUCTION - ONE CENTER STUDY.

- Cervical ripening can be promoted in many ways, but mechanical methods are among the oldest. Like all other methods, this one also has its pros and cons. Disadvantages compared to pharmacological methods include some maternal discomfort upon manipulation of the cervix, a theoretical increase in the risk of maternal and neonatal infection from the introduction of a foreign body, potential disruption of a low-lying placenta, and increase in the need of oxytocin induction of labor. The aim of the study was to evaluate the effect of using cervical ripening balloon in preinduction on the mode of delivery. This was a longitudinal, cohort, intervention, non-randomized one center study. Inclusion criteria were term pregnancies with gestational diabetes, oligohydramnios, intrauterine growth restriction, gestational hypertension/preeclampsia and pregnancies after 41 weeks of pregnancy. Preinduction of labor was performed in term pregnancies at Sestre milosrdnice University Hospital Center. Results in the first 150 women having undergone labor preinduction with cervical ripening balloon were included. Two-sided p values <0.05 were considered significant. Statistical analysis was done using SPSS Version 20.0. The study included 150 women; one woman was excluded from further analyses due to conversion of fetal presentation (head to breech). Indications for labor preinduction were as follows: gestational diabetes, oligohydramnios, intrauterine growth restriction, gestational hypertension/preeclampsia and pregnancies after 41 weeks of pregnancy. Women with normal vaginal delivery (96/149) had lower rates of gestational diabetes and oligohydramnios and used epidural analgesia more frequently. Women with dystocia (32/53) had a significantly longer labor duration and higher neonatal birth weight. In multivariate analysis, multiparity, greater cervical dilatation after balloon removal and use of epidural analgesia were associated with a decreased risk of cesarean section, while the presence of gestational diabetes and oligohydramnios was associated with an increased risk of cesarean section. We found this preinduction method safe and efficient, with a potential to increase the rate of vaginal deliveries.

Effect of epidural analgesia on mode of delivery.

Continuous epidural analgesia is considered to be the gold standard of pain relief in labour. The objective of this study was to examine the connections between epidural analgesia and the frequency of instrument-assisted deliveries. We retrospectively analysed data encompassing epidural analgesia applications during 2012 and the connections with an increased frequency of instrumental deliveries. Out of 3157 births in 2012, epidural analgesia was used in 443 (14.03 %). Epidural analgesia significantly increased the number of instrumental deliveries with vacuum extraction (χ2 = 35.01; df = 1; p < 0.01) and the number of emergency caesarean sections (χ2 = 18.01; df = 1; p < 0.01). A significantly higher percentage of dystocia leading to emergency caesarean sections was noted in deliveries with epidural analgesia (χ2 = 6.15; df = 1; p < 0.05). An increase in instrumental delivery incidence seems to be an acceptable risk in view of epidural analgesia-related positive effects that future mothers should be informed of.

Do Changing Diagnostic Criteria for Gestational Diabetes Influence Pregnancy Outcome?

The incidence of pregnancy related diabetes has been steadily increasing during the past decade. The aim of this retrospective study was to evaluate the type and prevalence of gestational diabetes complications after implementing new diagnostic criteria for gestational diabetes. The incidence of gestational diabetes, maternal age, mode of delivery and birth weight were analyzed. Study patients were divided into three groups. The first group consisted of patients who gave birth during 2005, the second group during 2011 and the third group during 2012. In 2005, the World Health Organization criteria were used on diagnosing gestational diabetes, whereas in 2011 and 2012 the criteria issued by the International Association of Diabetes and Pregnancy Study Groups were considered. There was no statistically significant difference among the groups according to maternal age, birth weight (p=0.203) and mode of delivery (p=0.883). Cesarean section was performed in about 30% of deliveries in all groups combined. There was no significant difference in the number of neonatal hypertrophy (p=0.348), although the distribution of hypertrophy showed a tendency towards higher values in 2005. The incidence of gestational diabetes was 2.2% in 2005, 6.6% in 2011 and 12% in 2012. In conclusion, difference in the incidence of pregnancy related diabetes appeared to have resulted directly from using different diagnostic criteria. The new criteria contributed to a relatively higher incidence of gestational diabetes but also achieved better gestational glycemic control and consequently better fetal growth regulation.

The Croatian Model of Integrative Prospective Management of Epilepsy and Pregnancy

Epilepsy is the most common neurological complication in pregnancy. Women with epilepsy have a higher risk of complications in pregnancy. In Croatia, women with epilepsy are treated by neurologists at tertiary centers according to the place of residence. We prospectively followed-up pregnancies in women with epilepsy and healthy controls, and analyzed the factors responsible for their delivery outcomes and development of their babies. Healthy pregnant women had a higher level of education and economic status, but pregnant women with epilepsy took folic acid in a higher proportion than controls, possibly due to timely preconception counseling. Complications during pregnancy depended on the number of antiepileptic drugs and epilepsy control. We noticed some behavioral and cognitive aspects in children exposed in utero to valproic acid, which required follow up. The rate of congenital malformations was not increased. In conclusion, women with epilepsy should receive preconception counseling about the risk for pregnancy, but also about the possibilities to minimize that risk. We have introduced a model of integrative management of pregnancy and epilepsy based on close collaboration among different clinical experts in Croatia, in order to provide prompt counseling and timely intervention.
