RESUMEN

Child abuse and neglect includes any behavior that harms the child or hinders the child's development. The aim of this study was to determine the demographic and clinical characteristics of patients with suspected child abuse or neglect in the pediatric emergency department. Between July 2017 and July 2022, patients admitted to our pediatric emergency department and consulted to the medical social services unit with a preliminary diagnosis of neglect and/or abuse were retrospectively scanned through the registry system. The patients were divided into five groups according to their victimization: physical, sexual, and emotional abuse; neglect; and medical child abuse (MCA)-Munchausen by proxy. A total of 371 children were included in the study. Two hundred twenty-two (59.8%) of the patients were female and the median age was 161 months [IQR (46-192)]. Then, 56.3% of the patients were in the adolescent age group. The most common admission time period was between 16.00 and 24.00 (n 163, 43.9%). Then, 24.2% of the patients were exposed to physical abuse, 8.8% to sexual abuse, 26.1% to emotional abuse, 50.4% to neglect, and 3.2% to MCA. One hundred eight (29.1%) patients were followed up as inpatients in the pediatric intensive care unit. Four of the patients (1%) had out-of-hospital cardiac arrest, and the deaths were in patients under 2 years of age.  Conclusion: Pediatric emergency departments are one of the important units visited by child maltreatment patients. Victimized children may reflect their silent screams with various clinical presentations. Infants are at the greatest risk of suffering serious or fatal injuries. Health professionals working in the emergency department have an important role in detecting, treating, and preventing recurrence of child neglect and abuse. What is Known: • The pediatric emergency department is an important entry point in the health care system for children who experience maltreatment. • It has a wide spectrum of physical, sexual, emotional abuse and neglect. What is New: • A high index of suspicion is required to diagnose cases of child maltreatment. • Infants are at the greatest risk of suffering serious or fatal injuries.

RESUMEN

The wingless/integrase-1 (WNT) pathway involved in the pathogenesis of inflammatory airway diseases has recently generated considerable research interest. Montelukast, a leukotriene receptor antagonist, provides therapeutic benefits in allergic asthma involving eosinophils. We aimed to investigate the role of the WNT pathway in the therapeutic actions of montelukast (MT) in a mixed type of allergic-acute airway inflammation model induced by ovalbumin (OVA) and lipopolysaccharide (LPS) in mice. Female mice were sensitized with intraperitoneal OVA-Al(OH)3 administration in the initiation phase and intranasal OVA followed by LPS administration in the challenge phase. The mice were divided into eight groups: control, asthmatic, and control/asthmatic treated with XAV939 (inhibitor of the canonical WNT pathway), LGK-974 (inhibitor of the secretion of WNT ligands), or MT at different doses. The inhibition of the WNT pathway prevented tracheal 5-HT and bradykinin hyperreactivity, while only the inhibition of the canonical WNT pathway partially reduced 5-HT and bradykinin contractions compared to the inflammation group. Therefore, MT treatment hindered 5-HT and bradykinin hyperreactivity associated with airway inflammation. Furthermore, MT prevented the increases in the phosphorylated GSK-3ß and WNT5A levels, which had been induced by airway inflammation, in a dose-dependent manner. Conversely, the MT application caused a further increase in the fibronectin levels, while there was no significant alteration in the phosphorylation of the Smad-2 levels in the isolated lungs of the mice. The MT treatment reversed the increase in the mRNA expression levels of interleukin-17A. An increase in eosinophil and neutrophil counts was observed in bronchoalveolar lavage fluid samples obtained from the mice in the inflammation group, which was hampered by the MT treatment. The inhibition of the WNT pathway did not alter inflammatory cytokine expression or cell infiltration. The WNT pathway mediated the therapeutic effects of MT due to the inhibition of GSK-3ß phosphorylation as well as the reduction of WNT5A levels in a murine airway inflammation model.

RESUMEN

Background: The gypsy moth (Lymantria dispar L., Lepidoptera: Erebidae) is a worldwide pest of trees and forests. Lymantria dispar nucleopolyhedrovirus (LdMNPV) belongs to the Baculoviridae family and is an insect virus specific to gypsy moth larvae. In this study, we describe the complete genome sequences of three geographically diverse isolates, H2 (China), J2 (Japan), and T3 (Turkey), of Lymantria dispar multiple nucleopolyhedrovirus (LdMNPV). Methods: The genomes of isolates H2, J2, and T3 were subjected to shotgun pyrosequencing using Roche 454 FLX and assembled using Roche GS De Novo Assembler. Comparative analysis of all isolates was performed using bioinformatics methods. Results: The genomes of LdMNPV-H2, J2, and T3 were 164,746, 162,249, and 162,614 bp in size, had GC content of 57.25%, 57.30%, and 57.46%, and contained 162, 165, and 164 putative open reading frames (ORFs ≥ 150 nt), respectively. Comparison between the reference genome LdMNPV-5/6 (AF081810) and the genomes of LdMNPV-H2, J2, and T3 revealed differences in gene content. Compared with LdMNPV-5/6, ORF5, 6, 8, 10, 31, and 67 were absent in LdMNPV-H2, ORF5, 13, and 66 were absent in LdMNPV-J2, and ORF10, 13, 31, and 67 were absent in LdMNPV-T3. In addition, the gene encoding the mucin-like protein (ORF4) was split into two parts in isolates H2 and T3 and designated ORF4a and ORF4b. Phylogenetic analysis grouped isolates H2 and J2 in a different cluster than isolate T3, which is more closely related to the Turkish and Polish isolates. In addition, H2 was found to be closely related to a South Korean LdMNPV isolate. Conclusion: This study provided a more detailed overview of the relationships between different geographic LdMNPV isolates. The results showed remarkable differences between groups at the genome level.

RESUMEN

OBJECTIVE: To evaluate the changes in the diameters of superior vena cava (SVC) and inferior vena cava (IVC) and to measure the ratio between SVC and IVC in growth-restricted fetuses and compare these results with normally grown fetuses. METHODS: Twenty-three consecutive patients with fetal growth restriction (FGR) (Group I) and 23 pregnant gestational age-matched controls (Group II) between 24 and 37 weeks of gestation were enrolled in the study between January 2018 and October 2018. The diameter of the SVC and IVC from inner wall to inner wall was measured in all patients by sonographic examination. The ratio between the diameter of the SVC and IVC was also measured in each patient to eliminate the gestational age factor. We have named this ratio the "vena cava ratio" (VCR). All parameters were compared between the two groups. RESULTS: The diameter of the SVC was significantly greater in the fetuses with FGR (2.6-7.7 [5.4]) than in controls (3.2-5.6 [4.1]; P = .002; P < .01). The diameter of the IVC was significantly less in the fetuses with FGR (1.6-4.5 [3.2]) than in controls (2.7-5 [3.7]; P = .035; P < .05). The VCR was between 1.1 and 2.3 and the median value was 1.8 in Group I. The VCR was between 0.8 and 1.7 and the median value was 1.2. VCR was significantly higher in fetuses with FGR (P = .001 P < .01). CONCLUSION: This study shows that VCR is higher in fetuses with growth restriction. Further studies are needed to clarify the association between VCR and antenatal prognosis and postnatal results.

RESUMEN

Our objective is to investigate maternal midtrimester plasma and amniotic fluid (AF) levels of angiopoietin-2 (Ang-2) and thrombomodulin (TM), which are involved in vascular remodelling and endothelium activation, in placental disorders including foetal growth restriction (FGR) and preeclampsia (PE). This prospective multiparametric pilot study was conducted at the Perinatology Division of Trakya University in a population undergoing genetic amniocentesis. Both AF and plasma aliquots were kept in -80 °C until ELISA assay. The pregnancies were followed up until the end of gestation in terms of obstetric results. Amniotic fluid and plasma aliquots from 127 pregnancies who underwent genetic amniocentesis between 16 and 24 weeks of gestation were analysed. During the final data evaluation, 39 were excluded with various reasons. Twelve subsequently developed FGR and 11 complicated with PE. The control group (n = 65) was consisted of women delivered >37th week with an uncomplicated outcome. The midtrimester maternal Ang-2 levels in both AF and plasma and also TM levels in plasma were found to be significantly increased in pregnancies who subsequently developed FGR or PE (p< .05). The midtrimester Ang-2, which rises in both plasma and AF and the midtrimester TM, which only significantly increase in plasma compartment in PE group, as compensatory mechanism may be the precursors of placental disorders including FGR and PE.Impact StatementWhat is already known on this subject? It is known that angiopoietin-2 (Ang-2) has important role in placental angiogenesis and vascular remodelling. TM which is a receptor for Ang-2 plays a protective role in pregnancy by preventing the uteroplacental circulation from thrombosis.What do the results of this study add? The present study demonstrates that both midtrimester maternal plasma Ang-2/TM and amniotic fluid (AF) Ang-2 levels were significantly higher in PE and FGR group than uncomplicated group. Midtrimester AF TM levels were not significantly higher in PE group than the control group.What the implications are of these findings for clinical practice and/or further research? In the clinical practice, high levels of midtrimester Ang-2 and TM in plasma may be used for the prediction of FGR and PE. Although amniocentesis is not practical in the clinical use, the levels of these two markers in both AF and plasma compartments may contribute to explain the pathophysiology of FGR and PE.

RESUMEN

Cloacal dysgenesis sequence occurs as a result of complete developmental failure of the urorectal septum. Typically, the sequence is featured by a smooth perineum, without any urethral, genital or anal openings. Its clinical manifestation differs throughout gestation. We report an interesting case of first trimester megacystis with associated umbilical cord abnormalities in a female fetus having cloacal dysgenesis sequence. This rare association reflecting high urinary pressure should first suggest urethral atresia. Our case highlights the importance of routine inspection of umbilical cord in the workup of early megacystis in terms of both etiology and fetal diagnosis.

RESUMEN

AIM: To compare the immediate-release (IR) and osmotic push-pull system formulations of nifedipine used for tocolysis in prolonging pregnancy, neonatal outcomes and maternal-fetal adverse effects. METHODS: We evaluated 140 pregnant women who received the IR (n = 72) and osmotic push-pull system (n = 68) formulations of nifedipine for tocolysis due to threatened preterm labor between 240/7 and 336/7 weeks of gestation. Groups were compared in terms of efficacy of tocolysis in prolonging pregnancy for more than 48 h, 7 days and up to 37 weeks of gestation, total number of days gained for prolonging pregnancy, delivery weeks, maternal-fetal adverse effects and neonatal outcomes including ventilation support, need for intubation or surfactant, intraventricular hemorrhage, respiratory distress syndrome, necrotizing enterocolitis, admission to neonatal intensive care unit, neonatal death, Apgar scores at the 1st and 5th minutes. RESULTS: There was no significant difference between the two groups in prolonging pregnancy for more than 48 h or 7 days, total number of days gained after tocolysis initiation, delivery weeks, the number of births at 340/7 -366/7 weeks or after 37 weeks of gestation (P > 0.05). Maternal-fetal adverse effects and neonatal outcomes were similar in both groups (P > 0.05). CONCLUSION: The efficacy of IR and osmotic push-pull system formulations of nifedipine have similar effects in terms of tocolysis and neonatal outcomes, adverse effects. Osmotic push-pull system formulation of nifedipine may be an alternative medication in tocolytic therapy due to its ease of use and the absence of loading dose necessity.

RESUMEN

Amniotic band syndrome can lead to a wide spectrum of congenital abnormalities including orofacial and visceral defects. It is associated with malformations in truncal, craniofacial regions and the limbs, whereas it sometimes may imitate some genetic disorders. Here, we present an atypical case mimicking amniotic band syndrome with a facio-upper arm band that was having multiple fetal structural abnormalities including scoliosis, bilateral cleft lip and palate, upper limb abnormality, unilateral anophthalmia with contralateral microphthalmia, left hypertrophic kidney and severe ventriculomegaly.

RESUMEN

OBJECTIVE: To investigate whether myometrial thickness (MT) to cervical length (CL) ratio could be used in the prediction of preterm birth (PTB) in singleton pregnancies presented with threatened preterm labor (TPL). METHODS: After 48 h of successful tocolysis, MT was measured transabdominally from the fundal, mid-anterior walls and the lower uterine segment (LUS) in 46 pregnancies presented with TPL. MT measurements were divided into CL, individually. The main outcome was PTB before 37 weeks of gestation. RESULTS: The patients were divided into two groups as women delivered ≥ 37 weeks (38.68 ± 1.01 weeks) (n = 25) and those delivered < 37 weeks (34.28 ± 2.53 weeks) (n = 21). The mean ± SD CL in the preterm delivery group was significantly shorter than the term delivery group (23.77 ± 9.23 vs 29.91 ± 7.03 mm, p < 0.05). Fundal, mid-anterior or LUS MT values were similar in both groups. However, in those who delivered preterm, the ratios of fundal MT-to-CL (p = 0.026) and mid-anterior MT-to-CL (p = 0.0085) were significantly different compared to those delivered at term. The optimal cutoff values for CL, fundal MT-to-CL and mid-anterior MT-to-CL ratios in predicting PTB were calculated as 31.1 mm, 0.19 and 0.20, respectively. Fundal MT-to-CL ratio predicted preterm delivery with 71% sensitivity, 72% specificity, 68% positive and 75% negative predictive values. For mid-anterior MT-to-CL ratio, respective values were 76, 76, 73 and 79%. CONCLUSION: Measurement of MT along with CL may offer a promising method in the management of women presented with TPL.

RESUMEN

Background: Schizencephaly is a neuronal migration anomaly characterized by presence of a cleft between ependymal layer of the ventricle and pia mater of the cerebral cortex. It may be associated with additional cerebral abnormalities, including polymicrogyria, pachygyria, gray matter heterotopy, ventriculomegaly and corpus callosum agenesis. Case Report: We present a female fetus with schizencephaly accompanied by occipital encephalocele, polymicrogyria, agenesis of the corpus callosum, dysmorphic facies and cardiac muscular ventricular septal defect. Array comparative genomic hybridization (array-cGH) analysis revealed a deletion of chromosome 22q13.32 including FAM19A5 gene that is a member of TAFA family. Conclusions: Schizencephaly may be accompanied by unexpected structural and genetic anomalies as in our case with occipital encephalocele, dysmorphic facies, cardiac ventricular septal defect and chromosome 22q13.32 deletion.

RESUMEN

Amsacta moorei entomopoxvirus (AMEV) infects certain lepidopteran and orthopteran insects and is the most studied member of the genus Betaentomopoxvirus. It has been considered as a potential vector for gene therapy, a vector to express exogenous proteins and a biological control agent. One of its open reading frames, amv248, encodes a putative glycosyltransferase and is the only known attachment protein conserved in AMEV and chordopoxviruses. The ORF was successfully expressed and the protein was shown to bind soluble heparin, both in silico and in vitro. Our results also showed that, while viral infection was inhibited by soluble glycosaminoglycans (GAGs), GAG-deficient cells were more resistant to the virus. Finally, we revealed that amv248 encodes an active heparin-binding glycosyltransferase which is likely to have a key role in the initiation of infection by AMEV.

RESUMEN

Posterior encephalocele is a neural tube defect, which is a sac-like protrusion of the neural tissue and cerebrospinal fluid through a defect in the occipital bone. This embryonic anomaly may coexist with cortical dysplasia, agenesis of the corpus callosum, hydrocephalus, microcephaly, craniofacial abnormalities, ventricular and atrial septal defect. We report a case of a large posterior encephalocele in a fetus accompanied by unexpected major abnormalities including transposition of the great arteries, severe ventriculomegaly and cerebellar atrophy. Postnatal surgical corrections of the posterior encephalocele and then of the transposition of the great arteries were performed but the neonate died 2 months after delivery.

RESUMEN

OBJECTIVES: Uterine arcuate artery calcification is an incidental finding on transvaginal sonography. We conducted this study to evaluate the clinical importance of arcuate artery calcification and its association with the serum lipid profile and carotid artery atherosclerosis. METHODS: Serum lipid profiles, carotid artery intima thicknesses, and Doppler parameters of uterine arteries were examined in 25 patients with uterine arcuate artery calcification and 25 control participants. The parameters were compared between the groups. RESULTS: The mean pulsatility indices, mean resistive indices, and systolic-to-diastolic ratios of the right and the left uterine arteries were significantly higher in the calcification group (P< .01). Serum total cholesterol and low-density lipoprotein cholesterol levels were significantly higher, whereas the serum high-density lipoprotein cholesterol level was significantly lower in patients with uterine arcuate artery calcification than controls (P < .01). Right and left common carotid artery intima thicknesses were also significantly higher in the calcification group (P < .01). CONCLUSIONS: Uterine arcuate artery calcification is an incidental finding on transvaginal and transabdominal pelvic sonography, and it is correlated with an abnormal lipid profile and increased thicknesses of the intimal layers of the carotid arteries. We suggest that an incidental finding of arcuate artery calcification during vaginal sonography is a reason to screen for generalized atherosclerosis and related disorders.

RESUMEN

Tetrasomy 18p, characterized by the presence of four copies of the short arm of chromosome 18, is considered to occur with the nondisjunction in meiosis II after the errors in the meiotic and early postmeiotic mitotic division in the centromere. It is accompanied by various abnormalities including congenital heart defects, lower extremity abnormalities, micrognathia, high arched palate, kyphoscoliosis, microcephaly, myelomeningocele, hernia and renal anomalies. We present the first case of a dichorionic diamniotic twin pregnancy in which both fetuses were affected by tetrasomy 18p, but with discordant morphology, detected in one twin in the first but in the other in the second trimester.

RESUMEN

OBJECTIVE: To determine the biochemical and hormonal differences in polycystic ovary syndrome (PCOS) patients with and without polycystic ovary (PCO) morphology and to evaluate the outcomes resulting from those differences. METHODS: The study included a total of 83 patients with PCOS; 43 of them had PCO morphology (Group-I) and 40 did not (Group-II). Serum LDL, HDL, total cholesterol, triglyceride (TG), total testosterone (T), follicle stimulating hormone (FSH), luteinizing hormone (LH), 17b-estradiol (E2), prolactin (PRL), thyroid stimulating hormone (TSH), sex hormone binding globulin (SHBG), glucose and insulin levels were determined. Homoeostatic model assessment insulin resistance (HOMA-IR) index was calculated. RESULTS: The two groups were similar with respect to BMI. The systolic and diastolic blood pressure measurements of Group-I were significantly lower (p<0.01). Serum mean level of LH (p=0.026) and the mean LH/FSH (p=0.001) level of Group-I were significantly higher than Group-II. The total cholesterol and triglyceride levels of Group-I were significantly lower (p<0.05, p<0.01). The mean HOMA-IR level of Group-I was significantly lower than Group-II (p=0.004). CONCLUSIONS: The group without PCO morphology had a higher risk than the other group in terms of increased insulin resistance, dyslipidemia and cardiovascular diseases due to effects of hyperandrogenism.

RESUMEN

OBJECTIVE: To document the neonatal outcomes of preterm birth in twin pregnancies and to investigate whether perinatal and obstetric parameters are associated with clinical outcomes. METHODS: This retrospective trial was conducted on data gathered from 176 preterm twins delivered in the obstetrics and gynecology department of our tertiary care center. Data extracted from medical files of 88 pregnant women who gave preterm birth (at 26(0/7) to 36(6/7) gestational weeks) to twins were analyzed. Maternal/fetal descriptive and obstetric parameters, sonographic data, route of delivery, indication for cesarean section, birth weight, Apgar scores, head circumference, umbilical cord length and placental weight were noted. RESULTS: The average age of the pregnant women was 28.8±6.4 years and ultrasonographic gestational age was 31.9±2.6 weeks. Apgar scores at 1(st) minute were affected significantly by fetal body weight (p=0.001), gestational age (p=0.001), height (p=0.004) and head circumference (p=0.011). None of these variables exhibited a noteworthy effect on Apgar scores at 5(th) minute. CONCLUSION: Efforts must be made to achieve advancement of gestational age until delivery in the follow-up preterm of twins. A well-established algorithm with special emphasis to risk factors is necessary to standardize and popularize the appropriate management strategy.

RESUMEN

OBJECTIVE: To evaluate the importance of saline infusion Doppler sonohysterography (SIS-D) in the assessment of transvaginal ultrasound (TVUSG)-suspected intrauterine mass lesions in women complaining about abnormal uterine bleeding with respect to hysteroscopy (H/S) and pathologic diagnosis. METHODS: This study was conducted on patients, who visited to our clinic with abnormal uterine bleeding and whose TVUSGs indicated intrauterine masses. The study covered a total of 100 patients. SIS-D and hysteroscopy were performed on those 100 patients. SIS-D results were compared with hysteroscopy results. The relation between SIS-D findings and pathology results were evaluated. RESULTS: For SIS; specificity was 96%, sensitivity was 60%, positive predictive value (PPV) was 87.8%, negative predictive value (NPV) was 83.3%, and the accuracy rate was 87%. For TVUSG; PPV was 75%. According to SIS-D, 92.2% of the lesions that had single-vessel feeding patterns were endometrial polyps, and this was statistically significant (p<0.0001). 57.1% of the lesions that had multiple-vessel feeding patterns were submucous myomas, and this was statistically significant (p<0.0001). CONCLUSION: SIS should be performed in patients before hysteroscopy because it will protect a considerable number of patients from unnecessary invasive procedures. SIS-D gives an idea on the histopathology of the mass.

RESUMEN

PURPOSE: To evaluate the effect of adding tea tree oil to denture liners on Candida albicans and bond strength to the acrylic denture base. MATERIALS AND METHODS: Disc-shaped specimens were fabricated from silicone-based resilient liner (Tokuyama, Molloplast), acrylic-based hard liner (GC Reline), and acrylic-based soft liner (Visco-gel). Tea tree oil (TTO) was incorporated into the liners at varying concentrations (0% [control], 2%, 5%, 8%). C albicans were counted by viable colony count, and optical density (OD) was measured with a spectrophotometer. The tensile strength to heat polymerized acrylic denture base was measured in a universal testing machine. The compliance of the data to the distribution of normality was evaluated using the Shapiro Wilk test. Two-way ANOVA, Bonferroni correction, and paired sample t test were performed (α = .05). RESULTS: The addition of TTO into liners provided a significant decrease in the OD values (P < .001). The control groups of the liners presented the highest colony counts, whereas increasing TTO decreased the results (P < .01). According to tensile bond strength test, 8% TTO addition resulted in a significant decrease for Tokuyama (P < .01) and Molloplast liners (P < .05), while 2% TTO resulted in significance for GC Reline (P < .001). CONCLUSIONS: Denture liners containing increasing percentages of TTO presented lower amounts of C albicans colonies and decreased bond strength to the denture bases. When using TTO for its antifungal properties, the amount added should be carefully selected because the tensile bond strength may be affected.

RESUMEN

Bernard Soulier Syndrome (BSS) is an inherited bleeding disorder characterized by macrothrombocytopenia and absence of ristocetin-induced platelet aggregation. Clinical findings vary from person to person. Most of the patients are diagnosed with muco-cutaneous bleeding such as purpura, epistaxis and gingival bleeding in early childhood. Few pregnant women with BSS are described in the literature. Management of thrombocytopenia during pregnancy and delivery requires a multidisciplinary approach. The family should be warned about the potentially life-threatening bleeding during pregnancy and the delivery and the decision about mode of delivery should be individualised, involving discussion with patient and multidisciplinary team.
