RESUMO

OBJECTIVES: This study focused on the link between skin disorders and Methylenetetrahydrofolate reductase (MTHFR) polymorphisms. METHODS: Study cases were taken from a pre-conceptional care program where patients with poor obstetric history were evaluated in terms of systemic disorders including skin diseases. This retrospective cohort (n = 472) consisted of 110 (23.3%) and 362 (76.7%) women with or without skin disorders, respectively. For ease of analysis, the history of skin diseases was classified into seven categories: (1) acne/rosacea/other acneiform disorders; (2) fungal disease; (3) pruritis/xerosis; (4) psoriasis vulgaris; (5) acrochordons and other benign skin growths; (6) urticaria/dermatitis; and (7) viral diseases. RESULTS: In this retrospective cohort of 472 women, we explored the impact of MTHFR A1298C and C677T polymorphisms on skin disorders. Despite similar allelic frequencies, our findings revealed a statistically significant association between the presence of MTHFR polymorphisms and skin disorders (p = .027). Subgroup analysis indicated significantly higher rates of MTHFR polymorphisms in patients with psoriasis vulgaris (p = .033) and acrochordons (p = .030), highlighting their potential relevance in specific skin disorder subtypes. CONCLUSIONS: The increased prevalence of psoriasis and acrochordons among women with MTHFR deficiency underscores the complex relationship between genetic factors and dermatological health. Our findings emphasized the critical role of MTHFR polymorphisms not only in poor obstetric history but also as significant contributors to skin disorders. This dual association highlights the importance of comprehensive preconception counseling, especially customized for women affected by skin disorders.

RESUMO

BACKGROUND: High self-renewal capacity and most permissive nature of umbilical cord blood (CB) results with successful transplant outcomes but low hematopoietic stem and progenitor cell (HSPC) counts limits wider use. In order to overcome this problem ex vivo expansion with small molecules such as Valproic acid (VPA) or Nicotinamide (NAM) have been shown to be effective. To the best of our knowledge, the combinatory effects of VPA and NAM on HSPC expansion has not been studied earlier. The aim of this study was to analyze ex vivo and in vivo efficacy of VPA and NAM either alone or in combination in terms of expansion and engraftment. METHODS: A total of 44 CB units were included in this study. To determine the ex vivo and in vivo efficacy, human CB CD34+ cells were expanded with VPA and/or NAM and colony forming unit (CFU) assay was performed on expanded HSPC. Xenotransplantation was performed simultaneously by intravenous injection of expanded HSPC to NOD-SCID gamma (NSG) mice (n = 22). Significance of the difference between the expansion groups or xenotransplantation models was analyzed using t-test, Mann-Whitney, ANOVA or Kruskal-Wallis tests as appropriate considering the normality of distributions and the number of groups analyzed. RESULTS: In vitro CD34+ HSPC expansion fold relative to cytokines-only was significantly higher with VPA compared to NAM [2.23 (1.07-5.59) vs 1.48 (1.00-4.40); p < 0.05]. Synergistic effect of VPA+NAM has achieved a maximum relative expansion fold at 21 days (D21) of incubation [2.95 (1.00-11.94)]. There was no significant difference between VPA and VPA+NAM D21 (p = 0.44). Fold number of colony-forming unit granulocyte-macrophage (CFU-GM) colonies relative to the cytokine-only group was in favor of NAM compared to VPA [1.87 (1.00-3.59) vs 1.00 (1.00-1.81); p < 0.01]. VPA+NAM D21 [1.62 (1.00-2.77)] was also superior against VPA (p < 0.05). There was no significant difference between NAM and VPA+NAM D21. Following human CB34+ CB transplantation (CBT) in the mouse model, fastest in vivo leukocyte recovery was observed with VPA+NAM expanded cells (6 ± 2 days) and the highest levels of human CD45 chimerism was detectable with VPA-expanded CBT (VPA: 5.42 % at day 28; NAM: 2.45 % at day 31; VPA+NAM 1.8 % at day 31). CONCLUSION: Our study results suggest using VPA alone, rather than in combination with NAM or NAM alone, to achieve better and faster expansion and engraftment of CB HSPC.

RESUMO

Objective: To demonstrate the impact of scoliosis on pregnancy and gestational outcome. Material and Methods: We retrospectively evaluated gestational outcomes of pregnant women with scoliosis at Hacettepe University Hospital between 2008 and 2018. Cases were grouped according to the presence of previous scoliosis surgery and compared in terms of gestational week at birth, birthweight, rate of neonatal intensive care unit admission, hospitalization during pregnancy, route of delivery, type of anesthesia at labor and postpartum intensive care unit admission rate. Ejection fraction (EF), functional vital capacity (FVC), forced expiratory volume (FEV1) and FEV1/FVC ratio values were also recorded. Results: A total of 23 women were included, of whom 12 (52.2%) had a prior scoliosis surgery. One of the 23 (4.3%) cases was terminated due to respiratory problems, while the remaining 22 cases resulted in deliveries. The median gestational week at birth was 38.2 and the median birth weight was 3150 g. Median (range) maternal height was 143 (80-160) cm while median (range) maternal weight was 51 (35-86) kg. Three (13.6%) were diagnosed with restrictive lung disease. No significant difference was found between operated and non-operated groups in terms of respiratory function test results, cardiac EF and other related demographic and clinical features. Overall cesarean delivery rate was 63.6% (14/22) and cesarean section rate was significantly higher in the operated group (83.3% versus 40%) (p=0.04). Conclusion: Cesarean section rate was increased in this cohort of pregnancies in women with scoliosis and who had previous scoliosis surgery.

RESUMO

Background: Autophagy is a catabolic process whereby organelles and long-lived proteins are recycled through lysosomes to maintain cellular homeostasis. This process is being widely studied using culture techniques and animal models; however, cervicovaginal smears have not been used to detect autophagy. Aims: Our study aims to detect and evaluate autophagy in normal, malignant, infectious, and atypical cells in cervicovaginal smears by using cytological and immunocytochemical methods. Materials and Methods: Papanicolaou-stained 200 cervicovaginal smears were examined and 55 of 200 (27.5%) smears containing negative for intraepithelial lesion or malignancy (NILM) with identifiable infections and/or reactive/reparative changes (INF); briefly, NILM-INF (n = 31, 56.4%), atypical (n = 4, 7.3%), and malignant cells (n = 20, 36.3%) were evaluated as a study group. One hundred forty-five of 200 (72.5%) normal smears were accepted as the NILM without any identifiable infections (control group). The autophagy marker protein Microtubule-associated protein 1 light chain 3 A (MAP1LC3A) was used for immunocytochemical examination. Results: The staining intensity of the MAP1LC3A protein and autophagy positivity were lower in the malignant cells; however, they were higher in the NILM-INF and atypical cells. A statistically significant correlation between the malignant and normal cells was obtained for the autophagy positivity (P = 0.012). In view of the staining intensity of MAP1LC3A protein by the H-score method, a significant correlation was found between the NILM-INF and the normal cells (P = 0.015). Conclusions: Autophagy was detected in various cervicovaginal smears for the first time in this study. Our findings indicate that an autophagy process is essential in infectious cells as well as in the transformation of atypical cells into malignant cells in carcinogenesis.

RESUMO

The cervicovaginal microbiota is an essential aspect of women's reproductive and overall health. In this study, we aimed to evaluate the probiotic properties of a cervicovaginal isolate, obtained from a gynecologically healthy woman and assess its antagonistic effect against various microorganisms isolated from the vagina. Cytological examination was performed using Papanicolaou staining, and the isolated microorganism was identified via 16S Ribosomal RNA Gene Sequence Analysis. Probiotic characteristics were evaluated by determining the tolerance of the isolate to low pH, different NaCl concentrations, and bile salts. Bacterial adherence to stainless steel sheets, antibiotic susceptibility, and antimicrobial activity tests were also conducted and analyzed. Antimicrobial tests and antagonistic activities were assessed through disc diffusion assays. The cervicovaginal isolate was identified as B. velezensis ON116948 and was found to be tolerant to low pH, high NaCl and 0.3% bile salts. Additionally, it exhibited adherence. With the exception of amoxicillin/clavulanic acid (AMC) (30 µg) and oxacillin (OX) (1 µg), this isolate was susceptible to all the antibiotics tested. Candida species did not grow on B. velezensis spread media, while B. velezensis was able to grow on C. albicans, C. glabrata, C. tropicalis, S. condimenti and S. epidermidis spread media with growth zones of 13.7 ± 0.6, 13.3 ± 0.6, 14.2 ± 4.4, 10.5 ± 0.5 and 16.0 ± 1.0 (around discs), respectively. Our findings suggest that the cervicovaginal B. velezensis ON116948 isolate exhibits probiotic properties and antagonistic activity. These results provide important insights into the potential use of this isolate as a probiotic for the prevention of vaginal infections.

RESUMO

OBJECTIVES: Cell-free DNA has been found in all body fluids, but DNAs emerging from locations that are not in direct contact with breath in exhaled breath condensate (EBC) are yet to be found. The potential of EBC for prenatal and cancer screening prompted us to investigate whether fetal DNA is present in maternal EBC. METHOD: A total of 20 pregnant women's EBC and blood samples were collected. Four Y chromosome-specific assays were tested on all EBC and plasma samples by quantitative PCR (qPCR). The best-performing assay was used for digital droplet PCR (ddPCR) on all EBC and the six plasma samples. RESULTS: The sex of the fetuses was accurately determined from plasma samples. DNA sequences could not be properly amplified in EBC samples by the qPCR. By ddPCR, the Y chromosome sequence was amplified in two of the 11 EBC samples, from women carrying male fetuses (2/11), and the Y chromosome sequence was not amplified in the EBC of women carrying female fetuses (9/9). Exhaled breath condensate ddPCR result's specificity was 100%, the detection rate of Y chromosome was 18.18% (2/11), and the corrected accuracy was 59.09%. CONCLUSION: Our finding of "the presence of fetal DNA in maternal EBC", despite the low detection rate, might have a major impact on prenatal diagnosis and cancer screening.

RESUMO

INTRODUCTION: The aim of this study was to identify early changes in the Wnt/beta-catenin signaling pathway in high-risk human papillomavirus (HPV) infected cervicovaginal cells and to correlate these changes with cell proliferation, apoptosis, and autophagic processes. METHODS: We evaluated 91 cervicovaginal smears of women with (n = 41) and without (n = 50) HPV-DNA. Smears were stained against beta-catenin, c-myc, secreted frizzled-related protein 4 (sFRP4), cleaved caspase-3, and the autophagy markers Beclin-1 and light chain 3B. In addition, sFRP-1, -2, -3, -4, -5 mRNA levels were determined by quantitative reverse transcription-PCR in primary keratinocytes and FaDu cells expressing HPV16-E6, -E7, or -E6E7. RESULTS: Our data indicated that the Wnt/beta-catenin signaling is activated in HPV (+) cervicovaginal cells that can already be detected in cells with no obvious changes in cellular morphology (HPV [+]/cyto [-]). These cells also had significantly higher sFRP4 levels when compared to HPV-negative samples. In primary keratinocytes, sFRP4 was found to be absent and sFRP1 and sFRP2 to be repressed in the presence of HPV16-E6 and E7. Interestingly, sFRP4 is expressed in FaDu cells and can be upregulated in the presence of E6E7. Curiously, SFRP4 expression correlated with an increase in the level of autophagic markers in HPV (+)/cyto (-) smears. CONCLUSION: In conclusion, the activation of the Wnt/beta-catenin signaling pathway and upregulation of sFRP4, paralleled by an activation of the autophagic pathway may represent predisposing cellular factors early after HPV infection which need to be further determined in larger study.

RESUMO

BACKGROUND: The rates of pregnancy losses (PLs) are increased by maternal risk factors such as autoimmune disorders (AD) and methylenetetrahydrofolate reductase (MTHFR) gene polymorphisms. OBJECTIVE: To evaluate singleton PLs before gestational week (gw) 22 among patients with AD and MTHFR polymorphisms. METHODS: Totally, 1108 singleton pregnancies in 243 women were categorized as: 1) 148 pregnancies in 33 patients with AD, 2) 316 pregnancies in 66 patients with MTHFR polymorphisms, 3) 644 pregnancies in 144 patients with AD +MTHFR polymorphisms. PLs were classified into subgroups: a) Chemical Pregnancy(CP), b) Blighted Ovum(BO), c) gw ⩽ 10, d) gw11-14 e) gw15-22, f) Ectopic Pregnancy(EP), g) Trophoblastic Disease(TD). Obstetric histories were compared using Beksac Obstetrics Index (BOI): [number of living child + (π/10)]/gravida. RESULTS: PL rates before gw22 were 39.2% (58/148), 33.2% (105/316), and 36.3% (234/644) in AD, MTHFR, and AD +MTHFR groups, respectively (p= 0.421). The rate of Pre-Prenatal Screening Period fetal losses (CP + BO + gw ⩽ 10 fetal losses + EP + TD) were 84.8%, 75.9%, and 77.8% in AD, MTHFR, and AD +MTHFR, respectively (p= 0.264). Gravidity ⩽ 4 versus those with gravidity ⩾ 5 had statistically significant differences in BOI (p< 0.001). CONCLUSIONS: PL rate before gw22 among singleton pregnancies with AD and/or MTHFR polymorphisms was 35.8%. The clinical findings seem to be more complicated in patients with gravidity ⩾ 5.

RESUMO

OBJECTIVE: To introduce the effect of a single course of betamethasone for pregnant women at risk of preterm delivery (PTD). MATERIALS AND METHODS: In this study, a single course of 12 mg Bethamethasone was administered twice in 24 h (between 24-34 gestational weeks) for antenatal corticosteroid prophylaxis. Four hundred ninety-three neonates fulfilled the inclusion criteria and they were categorized (259 singletons, 192 twins and 42 triplets who met the inclusion criteria) into two groups according to the utilization of antenatal corticosteroid as control (n = 202) and study (n = 291) groups. We used respiratory distress syndrome (RDS), congenital pneumonia, intraventricular hemorrhage (IVH), neonatal sepsis, and bronchopulmonary dysplasia (BPD) as primary outcomes for the evaluation of neonatal morbidity. RESULTS: Study and control groups were similar in terms of clinical characteristics. RDS, congenital pneumonia, neonatal sepsis, and BPD rates were significantly higher in the study group (betamethasone) (p = .05, p = .007, 0.003, and 0.004, respectively) between 24-34 gestational weeks (when the neonates of multiple pregnancies were excluded from the analysis, we have demonstrated that congenital pneumonia (p = .033) and neonatal sepsis (p = .030) were still significantly higher in the betamethasone group). The neonates of 24-28 gestational weeks were compared separately and we demonstrated that RDS (p = .012), congenital pneumonia (p = .022), IVH (p = .044), neonatal sepsis (p = .023), and BPD (0.001) were also more frequent in the study group. When the 28-32 gestational week data were compared, IVH (p = .020) and neonatal sepsis (p = .017) were more frequent in the single course betamethasone users. However, we could not demonstrate a significant difference between the control and study groups between 32-34 gestational weeks in terms of the primary neonatal outcomes used in this study. CONCLUSION: Single course antenatal betamethasone administration may be ineffective on the respiratory complications of preterm and very preterm infants while it may be unfavorable for extremely preterm infants. WHAT IS NEW ABOUT THE PAPER, WHAT COULD ADD TO THE CURRENT KNOWLEDGE: Pregnant women at risk for preterm labor must be under intensive antenatal care programs, and if possible, necessary precautions must be undertaken to prevent fetal hypoxia together with etiology specific treatments. This approach might contribute to better perinatal outcomes than just administering antenatal corticosteroid therapy.

RESUMO

OBJECTIVE: To demonstrate the impact of preterm birth on the cytological, cytomorphometrical, and nuclear parameters of neonatal buccal smears. METHODS: This study consisted of Early Preterm Neonates (EPN; ≤34th gestational week [gw]; n = 36), Late Preterm Neonates (LPN; 34th to <37th gw; n = 46), and Term Neonates (control; ≥37th gw; n = 56). Cytological evaluation and buccal cytome assay were performed using Papanicolaou and Feulgen methods, respectively. RESULTS: Cytological evaluation demonstrated that smear background was cleaner (P < .05) and there were less macrophages in the control group (P < .001). Cyto-morphometric analysis showed that the measurements of nuclear diameter, nuclear area, and nucleus-to-cytoplasm ratio were higher in the preterm (EPN and LPN) versus the control groups (P = .016, P < .001, and P < .001, respectively). We also demonstrated that staining intensity of the nucleus and cytoplasm were less intense in the EPN and LPN groups (P < .001). There was no statistically significant difference between the EPN and LPN groups for any parameters (P > .05). Buccal cytome assay showed that nuclear buds were more prevalent in term newborns compared to preterm neonates (P < .001). CONCLUSIONS: Morphological and cytological properties of neonatal buccal cells are influenced by preterm birth status, and buccal smears may be used as a tool to detect biological markers of neonatal health problems.

RESUMO

OBJECTIVE: To evaluate the obstetric outcomes of singleton high-risk pregnancies with a small size uterine fibroid. METHODS: This retrospective cohort study was conducted among 172 high-risk pregnant women who were followed-up by a single surgeon between 2016 and 2019. Pregnant women with preconceptionally diagnosed small size (< 5 cm) single uterine fibroids (n = 25) were compared with pregnant women without uterine fibroids (n = 147) in terms of obstetric outcomes. RESULTS: There was no statistically significant difference between the groups in terms of adverse pregnancy outcomes. The size of the fibroids was increased in 60% of the cases, and the growth percentage of the fibroids was 25% during pregnancy. Intrapartum and short-term complication was not observed in women who underwent cesarean myomectomy. CONCLUSION: Small size uterine fibroids seem to have no adverse effect on pregnancy outcomes even in high-risk pregnancies, and cesarean myomectomy may be safely performed in properly selected cases.

RESUMO

BACKGROUND: Acrochordons are benign hypertrophic lesions of the skin of which the pathophysiology is unclear. OBJECTIVE: This study aimed to examine the association of acrochordons with autoimmune disorders in patients with a poor obstetric history. METHODS: This retrospective cohort involved 350 female patients with poor obstetric history who were included in a preconceptional care program to investigate risk factors for obstetric complications. These patients were further investigated for the co-existence of autoimmune disorders (defined by either a diagnosis of autoimmune diseases or autoimmune antibody positivity) and acrochordons. RESULTS: An autoimmune disorder was present in 55.7% (195/350) of the patients. The rate of acrochordons was significantly higher in patients with autoimmune disorders (n= 195) compared to the control group (n= 155) (8.21% versus 2.58%, respectively) (p= 0.043). When the autoimmune disease positive (n= 58) and autoimmune antibody-positive (n= 137) groups were separately analyzed, acrochordons were found more frequently in the autoimmune disease group (p= 0.004). However, there was no statistically significant co-occurrence of autoimmune antibody positivity and the presence of skin tags (p= 0.135). CONCLUSION: There may be immune system-related biological mechanisms underlying the pathogenesis of acrochordons. Preconceptional counseling is beneficial for women with poor obstetric history and acrochordons.

RESUMO

PURPOSE: To demonstrate and understand the association of HPV infection and biofilm formation. METHODS: The study consisted of cervicovaginal samples of 72 women who were evaluated at the colposcopy unit. Papanicolaou staining was used for cytological examination while "Crystal Violet Binding" assay was performed to detect biofilm formation. RESULTS: HPV-DNA was positive in 55.5% (n = 40) of the patients. The biofilm formation rate was statistically significantly higher in the HPV-positive women (45%) compared to HPV-negative women (21.9%) (P < 0.05). There was a statistically significant relationship between the presence of single HPV and "high-risk HPV" types and biofilm formation (P < 0.05). Biofilm formation was found in 80% of women with abnormal smear demonstrating atypical epithelial cells (P < 0.05). CONCLUSION: Biofilm formation is more frequent at the cervicovaginal microbiota of patients with HPV infection. This finding is especially important in cases with atypical epithelial cells at their cervicovaginal smears.

RESUMO

OBJECTIVE: To evaluate the association between bacterial vaginosis (BV) and autoimmune antibody positivity. METHOD: We evaluated Papanicolaou-stained cervicovaginal smears of 210 patients with poor obstetric history who were admitted to a special preconception counselling programme. Cytological specimens with various types of microorganisms except for BV, epithelial cell abnormalities and other non-neoplastic findings, including inflammation were excluded from the cohort in addition to patients with autoimmune and chronic inflammatory diseases. The remaining study population (n = 121) was divided into two groups of patients with autoimmune antibody positivity (study group, n = 80) and patients without antibody positivity (control group, n = 41). RESULTS: The rate of BV was demonstrated to be 13.8% and 2.4% in the study and control groups respectively (P = .042). We also demonstrated that the anti-nuclear antibody was positive in 58.3% of the cases with BV. CONCLUSION: BV was found more frequently in patients with autoimmune antibody positivity to a statistically significant degree.

RESUMO

OBJECTIVE: To share our experience in diagnosis of congenital central nervous system (CNS) abnormalities by fetal magnetic resonance imaging (MRI). STUDY DESIGN: This study consisted of 110 pregnancies. Neurosonography (NS) findings were compared with MRI results. Anomalies were categorized into 10 groups: 1) Corpus callosum (CC) and cavum septum pellucidum (CSP) anomalies, 2) Neural tube defects (NTD), 3) Posterior fossa anomalies (PFA), 4) Primary ventriculomegaly (PVM), 5) Microcephaly, 6) Macrocephaly, 7) Periventricular leukomalacia (PVL), 8) Craniosynostosis, 9) Intracranial hemorrhage (ICH) and 10) Lumbosacral teratoma. Demographic features, clinical characteristics and perinatal outcomes of the study subjects were evaluated. RESULTS: Gestational weeks for NS and for MRI were 25.5 and 26.5 weeks, respectively. Fourteen (12.7%) pregnancies were terminated. PVM (n = 36, 32.7%), CC and CSP anomalies (n = 29, 26.3%), PFA (n = 11, 10%) and NTD (n = 11, 10%) were the most common fetal MRI indications. There were no statistically significant differences between the accuracy of fetal NS and fetal MRI for CC and CSP anomalies, NTDs, PFA and PVM (p = 0.09, 0.43, 0.45 and 0.23, respectively). However, fetal MRI was more accurate for the detection of normal anatomic findings in cases with suspected microcephaly, macrocephaly and craniosynostosis in NS when pooled together (p = 0.007). Furthermore, MRI also seemed to be advantageous in CC & CSP anomalies though it was not validated by statistical measures. No statistically significant difference was found for diagnostic performance of NS and MRI according to gestational week (p = 0.27). CONCLUSION: Fetal MRI in addition to NS may improve diagnostic accuracy in pregnancies with congenital CNS abnormalities.

RESUMO

OBJECTIVE: To investigate the reasons for decision-making and concerns of patients in the field of prenatal screening, invasive prenatal diagnostic testing (IPDT), and termination of pregnancy (TOP). STUDY DESIGN: This questionnaire-based study consisted of 107 pregnant women who were referred for prenatal screening to the Hacettepe University Hospital. The questionnaire given to patients was prepared from scratch since there is no standard set of questions measuring patients' feelings and concerns regarding prenatal screening/diagnosis, IPDT, and TOP. RESULTS: Our questionnaire results showed that it is possible to classify decision-making factors into 6 groups: psychological, social, fear, religious/faith, support, and trust. The majority of patients were undecided (48.6%) about IPDT if prenatal screening test results were risky. Only 23.4% of patients were willing to accept IPDT. On the other hand, 55.1% of patients were not willing to undergo TOP if the fetal karyotyping results were abnormal. Religious factors seem to be important in refusing IPDT and TOP. CONCLUSION: Physicians should re-evaluate their practice in the field of prenatal screening and diagnosis in light of the high refusal rates of IPDT and TOP. Understanding factors influencing women's decision-making processes provides insight for service providers to help women at high risk of having foetal anomalies to make better-informed choices.

RESUMO

AIM: Comparison of mean channels of cell volume, conductivity and light scatter (VCS) parameters of neutrophil, monocyte and lymphocyte, procalcitonin (PCT) and white blood cell count (WBC) during term and preterm labor to evaluate the impact of inflammation on the triggering mechanisms of uterine contractions. METHODS: This study is consisted of 16 preterm and 60 term pregnancies at the beginning of the first stages of the labor. Leukocyte VCS parameters, PCT plasma levels and WBC count were evaluated. RESULTS: We could not demonstrate statistically significant difference in between leukocyte VCS parameters in preterm and term deliveries (P ˃ 0.050 for all). WBC counts were 10.6 and 11.8 × 103 /µL in the preterm and term groups respectively (P = 0.270). PCT levels were 0.04 and 0.03 ng/mL for preterm and term pregnancies (P = 0.062). CONCLUSION: Inflammation related markers such as leukocyte VCS parameters, PCT values and WBC count does not differentiate at the first stage of labor in preterm and term deliveries. These variables do not seem to have a prominent role at the biological events behind preterm contractions.

RESUMO

OBJECTIVE: To evaluate the outcomes of cases of prenatally-diagnosed congenital pulmonary airway malformation (CPAM). METHODS: We retrospectively evaluated cases of prenatally-diagnosed CPAM between 2004 and 2018. Ultrasonographic features such as visualization of a fetal lung mass and heterogeneous pulmonary parenchyma were used for CPAM diagnosis. Prenatal and postnatal findings were compared in terms of accuracy regarding the CPAM diagnosis. RESULTS: The sample consisted of 27 cases. There were four cases in which the patients opted for the termination of pregnancy due to the severity of the lesion. A total of 23 neonates were delivered, and CPAM was confirmed in 15 cases. The median gestational age at delivery was 37 weeks (28-40 weeks) and the mean birth weight was 2,776 g. There were two neonatal deaths, one due to pneumothorax, and the other due to hypoplastic left heart syndrome (HLHS). A total of five patients with respiratory problems were operated in the postpartum period. There were eight misdiagnosis: bronchopulmonary sequestration (five cases), congenital lobar emphysema (two cases), and congenital diaphragm hernia (one case). CONCLUSION: A precise postnatal diagnosis is very important to organize the proper management of the pregnancies with fetuses with CPAM. The positive predictive value of the prenatal diagnosis of CPAM via ultrasonography is of 70.3%. The differential diagnosis of CPAM may be prolonged to the postpartum period in some cases.
