RESUMO

OBJECTIVE: This study aimed to analyze the histopathological and biochemical effects of dexmedetomidine on the rat uteri exposed to experimental ischemia-reperfusion injury. MATERIALS AND METHODS: Twenty-four female rats were randomly divided into three groups. Group 1 was defined as the control group. An experimental uterine ischemia-reperfusion model was created in Group 2. Group 3 was assigned as the treatment group. Similar uterine ischemia-reperfusion models were created for the rats in Group 3, and then, unlike the other groups, 100 µg/kg of dexmedetomidine was administered intraperitoneally immediately after the onset of reperfusion. In blood biochemical analysis, superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) activities and malondialdehyde (MDA), interleukin 1beta (IL-1ß), interleukin 6 (IL-6) and tumor necrosis factor-alpha (TNF-α) levels were measured. In the histopathological analyses, endometrial epithelial glandular changes (leukocytosis, cell degeneration) and endometrial stromal changes (congestion, edema) were analyzed using the tissue damage scoring system. RESULTS: It was observed that IL-1ß, IL-6, and TNF-α levels were significantly suppressed in Group 3 compared to Group 2 (p=0.001, p<0.001 and p=0.001, respectively). MDA level was noted as the highest in Group 2. The MDA value in Group 3 was measured at 5.37±0.82, which was significantly decreased compared to Group 2 (p<0.001). An increase in antioxidant enzyme activities (SOD and GSH-PX) was observed in Group 3 compared to Group 2 (p=0.001 and p=0.006, respectively). In our histopathological analysis, a significant improvement in endometrial epithelial glandular and endometrial stromal changes was revealed in Group 3 compared to Group 2 (p<0.001). CONCLUSIONS: In our study, it has been documented that dexmedetomidine protects the uterine tissue against ischemia-reperfusion injury.

RESUMO

OBJECTIVE: This study aimed to investigate the level of perinatal anxiety in pregnant women who considered vaginal birth after a cesarean section (VBAC) and evaluate its effect on the type of delivery. SUBJECTS AND METHODS: The study was planned as single-centered and analytical. It was performed with pregnant women planning VBAC, reached via Google Forms between February 23 and August 17, 2022. An online form consisting of the Patient Information Form and the Perinatal Anxiety Screening Scale-Turkish version (PASS-TR) was applied to the participants. The type of delivery was questioned by phone call. RESULTS: Ages of 162 pregnant women ranged from 22 to 40 years (mean=31.08±3.75). 54.9% (n=89) had a gestational week of 37 or more. 83.3% (n=135) had a vaginal delivery, and 54.3% (n=88) had a score of >16 on PASS-TR. PASS-TR total and subscale scores were higher in patients with known gynecological diseases (p<0.001). The total score of PASS-TR was higher in those aged between 18-30 years (p=0.027). The total number of pregnancies was higher in those with a PASS-TR score of ≤16 (p=0.007). There was no statistically significant difference between the total and subscale scores of PASS-TR with the type of delivery after cesarean section. CONCLUSIONS: Perinatal anxiety was determined in 54.3% of the pregnant women planning VBAC, and 83.3% had a successful vaginal delivery. Age, low gravida, and the presence of gynecological diseases were risk factors for anxiety. There was no relationship between the type of delivery after cesarean section and perinatal anxiety.

RESUMO

PURPOSE: The goal of this study is to investigate the association between the choroid and lower extremity venous insufficiency (LEVI). METHODS: This prospective cross-sectional study includes 56 patients with LEVI and 50 age/sex-similar control subjects. Choroidal thickness (CT) measurements from 5 different points were captured from all participants by optical coherence tomography. In the group with LEVI on physical examination, reflux at the saphenofemoral junction, and the diameter of the great and small saphenous veins were evaluated via color Doppler ultrasonography. RESULTS: The mean subfoveal CT was higher in the varicose group than in the control group (363.04±99.75µm vs. 320.30±73.46µm, P=0.013). In addition, the CTs at the temporal 3mm, temporal 1mm, nasal 1mm, and nasal 3mm distance from the fovea were higher in the LEVI group compared to the controls (for all, P<0.05). There was no correlation between CT and diameter of the great and small saphenous vein in patients with LEVI (for all, P>0.05). However, the great and small saphenous veins of patients with CT above 400µm were observed to be wider in patients with LEVI (P=0.027 and P=0.007, respectively). CONCLUSION: Varicose veins can be a feature of systemic venous pathology. Another component of systemic venous disease may be increased CT. Patients with high CT should be investigated for susceptibility to LEVI.

RESUMO

OBJECTIVES: We aimed to determine adverse reactions and influencing factors, within the scope of the number of patients and total infusions, in patients with primary immunodeficiencies receiving intravenous immunoglobulin (IVIG) replacement. MATERIALS AND METHODS: Children with primary immunodeficiencies receiving IVIG replacement in Izmir Dr Behcet Uz Children's Hospital, between June 2014 and June 2016, were included in our study. RESULTS: The total number of the patients receiving IVIG replacement was 145 (37 female, 108 male). The number of total IVIG infusions was 1214. Adverse reactions were observed in 44.8% of the patients and 14.2% of the infusions. Common variable immunodeficiency was the most common diagnosis of the patients and adverse reactions most commonly developed in this group (24.2%). In all infusions the most frequent adverse reaction was headache (7.8%); fever was the most frequent immediate side effect (3.9%), whereas headache was the most common delayed adverse effect (5.1%). By logistic regression analyses, history of adverse reaction to IVIG in previous infusions, existence of concomitant infectious disease, past or family history of atopic disease, to receive IVIG infusion at the first time, or being under 10 years old were found associated with adverse reactions. There was no correlation between the concentration of IVIG preparations and the rate of side-effect development. CONCLUSIONS: In our study no severe adverse reaction to IVIG was observed, but many mild or moderate side effects occurred. Therefore, IVIG indications must be well identified. Patients, family of the patients and health care workers must be informed for adverse reactions

RESUMO

A 28-year-old woman underwent amniocentesis at 18 weeks' gestation upon detection of increased fetal nuchal fold and parietal cephalocele on the second trimester ultrasound examination. Prenatal microarray showed a de novo unbalanced translocation resulting in a gain in 6q and loss in 18p. A female infant was delivered at 38 weeks' gestation. At birth, cephalocele and webbed neck were noted as major dysmorphic features. The case presented here shows how a combination of different genetic studies is used to accurately elucidate a chromosomal anomaly in a prenatal setting.

RESUMO

BACKGROUND: Chronic spontaneous urticaria (CSU) is a disease that seriously disturbs the quality of life of the patient. Currently there is no prognostic marker of the disease. Our aim in this study was to determine possible prognostic markers of CSU in children. METHOD: All patients younger than 18 years of age who were followed by the Pediatric Immunology and Allergy Clinic of Diyarbakir Children's Hospital with a diagnosis of CSU between June 2017 and February 2019 were included in the study. Clinical and laboratory findings were compared between the symptomatic patient group and the patient group that remained in remission for at least three months without use of medication. RESULTS: Of the 52 cases included in the study, 32 (61.5%) were male. Mean age at time of diagnosis was 9.4 ± 4.4 years. Twenty-four cases (46.2%) went into remission. Young age at the time of diagnosis and being in the initial months of the disease were found to be associated with good prognosis (p < 0.05). Among laboratory results, elevation in absolute neutrophil count and neutrophil/lymphocyte ratio (NLR) were found to be associated with poor prognosis (p < 0.05). NLR was positively correlated with disease duration (p < 0.05). CONCLUSIÓN: For childhood CSU, younger age and initial months of the disease are good prognostic indicators, while only neutrophil/lymphocyte count can be used as a remission marker

RESUMO

Background: The diagnostic values for the skin prick test (SPT) diameters and egg white-specific IgE (EW-sIgE) levels that will allow us to predict the result of the oral food challenge test (OFC) in the diagnosis of egg white allergy vary by the community where the study is carried out. Objective: This study aimed to determine the diagnostic values of SPT and EW-sIgE levels in the diagnosis of egg white allergy. Methods: 59 patients followed with the diagnosis of egg allergy September 2013 to September 2015 were included in our retrospective cross-sectional study. The patients were investigated in terms of egg and anaphylaxis history or the requirement of the OFC positivity. The demographic, clinical and laboratory findings of the cases were recorded, and they were compared with the patients with the suspected egg allergy but negative OFC (n = 47). Results: In the study, for all age groups, the value of 5mm in SPT was found to be significant at 96.4% positive predictive value (PPV) and 97.8% specificity and the value of 5.27kU/L for EW-sIgE was found to be significant at 76% PPV and 86.6% specificity for egg white. The diagnostic power of the SPT for egg white (AUC: 72.2%) was determined to be significantly higher compared to the diagnostic power of the EW-sIgE (AUC: 52.3%) (p < 0.05). Conclusion: Along with the determination of the diagnostic values of communities, the rapid and accurate diagnosis of the children with a food allergy will be ensured, and the patient follow-up will be made easier (AU)

RESUMO

BACKGROUND: Food protein-induced allergic proctocolitis (FPIAP) is characterised by inflammation of the distal colon in response to one or more food proteins. It is a benign condition of bloody stools in a well-appearing infant, with usual onset between one and four weeks of age. OBJECTIVE: Our objective was to examine the clinical properties of patients with FPIAP, tolerance development time as well as the risk factors that affect tolerance development. METHODS: The clinical symptoms, offending factors, laboratory findings, methods used in the diagnosis and tolerance development for 77 patients followed in the Paediatric Allergy and Gastroenterology Clinics with the diagnosis of FPIAP during January 2010-January 2015 were examined in our retrospective cross-sectional study. RESULTS: The starting age of the symptoms was 3.3±4.7 months (0-36). Milk was found as the offending substance for 78% of the patients, milk and egg for 13% and egg for 5%. Mean tolerance development time of the patients was 14.7±11.9 months (3-66 months). Tolerance developed before the age of one year in 40% of the patients. Tolerance developed between the age of 1-2 years in 27%, between the age of 2-3 years in 9% and after the age of 3 years in 5% of the patients. CONCLUSIONS: Smaller onset age and onset of symptoms during breastfeeding were found associated with early tolerance development. In the majority of the patients, FPIAP resolves before the age of one year, however in some of the patients this duration may be much longer

RESUMO

OBJECTIVE: Sleep is a vital function for human beings, which can be affected by several factors. Chronic pain is one of these factors where it is the most frequent cause for seeking medical care in combination with insomnia. The aim of this study is to examine the prevalence and relationship between sleep disturbance and chronic pain. PATIENTS AND METHODS: After approval, a total of 85 Family Medicine Units from over 170 in Tokat were randomly selected using a 50% sampling. A sample of 2635 subjects, over the age of 19 years, who were registered with the selected Family Medicine Units, were assessed due to gender, age group, and the urban/rural population size of Tokat using the stratified sampling method. The sample size distribution was calculated as 1515 urban subjects, 1120 rural subjects; 1345 female subjects, 1290 male subjects; 1123 subjects between 20-39 years of age, 1103 subjects between the ages of 40-64, and 409 subjects over 64 years of age. After sampling, subjects were invited to participate in the study via an invitation letter, and agreeing individuals were taken to the Family Medicine Unit for face-to-face meetings. Written, informed consent was obtained, along with demographic data. The presence of chronic pain was recorded. According to the presence of chronic pain, all subjects were separated into two groups as Group Chronic Pain and Group Non-Chronic Pain. The visual analog scale for pain intensity, and Pittsburgh Sleep Quality Index for sleep quality, were performed with all subjects. A multiple linear regression model was used to assess the predictors of sleep quality. Analyses were conducted using the Statistical Package for Social Sciences program (SPSS Inc., Chicago, IL, USA), version 20.0. The statistical significance for all analyses was set at p < 0.05. RESULTS: The mean global Pittsburgh Sleep Quality Index score of Group Chronic Pain (5.30 ± 4.29) was significantly higher than in Group Non-Chronic Pain (3.22 ± 3.30; p < 0.01). The mean Pittsburgh Sleep Quality Index scores of females (5.69 ± 4.40) were significantly higher than males (4.54 ± 3.96) in Group Chronic Pain (p = 0.000045). A total of 40.7% of patients in Group Chronic Pain, and 21.9% in Group Non-Chronic Pain demonstrated poorer sleep quality according to the Pittsburgh Sleep Quality Index scores, with a cut-off level > 5. A moderate positive correlation was found between the global Pittsburgh Sleep Quality Index and Visual Analog Scale scores (r = 0.310, p < 0.01). A multiple linear regression analysis showed that age, gender, income, Visual Analog Scale, and presence of depression were the significant predictors for Pittsburgh Sleep Quality Index score. CONCLUSIONS: The current study revealed that chronic pain and pain intensity are important predictors of sleep quality.

RESUMO

Formaldehyde (FA) is one of the most widely used chemical compounds in industrial field. It is described as toxic, particularly to the nervous system, the urogenital system, and the respiratory tracts. In this study, we determined the effects of acute oral exposure to FA in rabbit brain tissue. A total of 16 rabbits were selected and divided into 2 groups: formaldehyde group (group F) and control group (group C). FA was administered to group F at a rate of 40 mg/kg/day via a nasogastric tube for 5 days. Saline was similarly administered to the eight controls. All the animals were euthanized after 5 days of exposure, and brain tissue samples were collected in 10% neutral formalin and embedded in paraffin. To investigate the effects of FA on the apoptotic process, we examined active caspase-3, Bax, and Bcl-2 immunohistochemical expression and terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate -biotin nick-end labeling (TUNEL) reactivity in the rabbit brains. In addition, glial fibrillary acidic protein (GFAP) was biochemically assessed in brain tissue samples for neurotoxicity. We found that FA treatment caused a significant decrease in Bcl-2 expression and an increase in active caspase-3 and Bax expressions as well as an increase in the number of TUNEL-positive apoptotic cells. The GFAP level was found to be significantly higher in group F. In conclusion, acute oral exposure to FA caused DNA damage, apoptosis, and neuronal injury in the rabbit brains.

RESUMO

BACKGROUND: Isoflurane is a volatile anaesthetic that has been commonly used since 1980. The major metabolites of isoflurane are fluoride ion and trifluoroacetate, both excreted in the urine. AIM: This study manage to show the histopathological findings of ingested isoflurane on liver, kidney and lugs in an animal model. Twenty-one rabbits were selected and divided into three groups: Group Isoflurane-5 (I-5); Group Isoflurane-10 (I-10); and Group Control (C). Each group consisted of seven rabbits. I-5 and I-10 received 5 ml/kg and 10 ml/kg of liquid isoflurane, respectively, via nasogastric tube, while C received 5 ml/kg saline (0.9% NaCI). All animals in I-5 and I-10 were sacrificed without anesthetic drug administration. Tissue samples from livers, kidneys and lungs were collected, preserving tissue unity and avoiding infliction of any trauma. Samples were fixed in 10% formalin solution, embedded in paraffin blocks and sliced into 5 µm sections. To investigate the effects of isoflurane, sections were examined under light microscope and histopathological changes were scored. RESULTS: Mean injury scores and the appearance of portal lymphocyte infiltration in liver samples showed significant increases in I-5 and I-10 compared to C (p = 0.005, p = 0.001 and p = 0.001, respectively). Mean lung injury scores revealed significant increases after isoflurane treatment in I-5 and I-10 compared to C (p = 0.026 and p = 0.017, respectively). CONCLUSIONS: Ingested isoflurane led to mild liver and lung injuries in rabbits.

RESUMO

OBJECTIVE: The aim of the study is to evaluate paediatric patients with protein losing enteropathy (PLE). METHODS: Fourteen cases diagnosed as PLE were evaluated in terms of aetiologies, diagnostic methods, laboratory findings, treatment procedures and longterm prognosis. RESULTS: Four of the cases had coeliac disease, three intestinal lymphangiectasia, three giardia infection, one H pylori infection and three cytomegalovirus (CMV) infection. Histopathological examinations of duodenum specimens revealed total villous atrophy in four cases, lymphatic dilatation in three cases, severe nodular appearance in four cases and no pathology in four cases. All of the cases except patients with intestinal lymphangiectasia were controlled by the appropriate treatment given for the underlying disease. The cases with CMV infection were treated with only supportive treatment and gancyclovir therapy was not needed. CONCLUSION: When proteinuria is not detected in wellappearing children admitted with oedema, PLE must be considered.


OBJETIVO: El objetivo del estudio es evaluar a pacientes con enteropatía perdedora de proteínas (EPP). MÉTODOS: Catorce casos diagnosticados con EPP fueron evaluados en términos de etiologías, métodos de diagnóstico, resultados de laboratorio, procedimientos de tratamiento, y prognósis a largo plazo. RESULTADOS: Cuatro de los casos tenían enfermedad celíaca, tres padecían de linfangiectasia intestinal, tres sufrían de infección por giardias, uno tenía infección por H pylori, y tres presentaba infección por citomegalovirus (CMV). Los exámenes histopatológicos de especímenes duodenales revelaron atrofia de las vellosidades intestinales en cuatro de los casos, dilatación linfática en tres casos, apariencia nodular severa en cuatro casos, y ausencia de patología en cuatro casos. Todos los casos - excepto los pacientes con linfangiectasia intestinal - fueron controlados mediante el tratamiento adecuado para la enfermedad subyacente. Los casos con infección por CMV fueron tratados con tratamiento de apoyo, y no se necesitó terapia con ganciclovir. CONCLUSIÓN: Cuando no se detecta proteinuria en niños con buena apariencia ingresados con edema, hay que considerar principalmente la posibilidad de EPP.

RESUMO

BACKGROUND: Caudal anesthesia is widely used as intraoperative and postoperative analgesia in children's subumbilical surgeries such as on the urogenital system, lower extremities and lower abdomen to reduce the stress response to surgery and to facilitate the general anesthesia. AIM: The purpose of this study was to compare the effects of caudally administered bupivacaine and levobupivacaine of equal volume and concentration on motor block and postoperative pain in children undergoing circumcision surgery. PATIENTS AND METHODS: The prospective, randomized, double-blind study included 60 patients with ages ranging from 1-10 years and ASA (American Society of Anesthesiologists) physical status of I-II who underwent elective circumcision surgery. The patients were divided into two groups: group B received 0.5 ml/kg of bupivacaine 0.25% caudally and group L received 0.5 ml/kg of levobupivacaine 0.25% caudally. Postoperative pain was assessed by children's and infant's postoperative pain scale and motor block was assessed by the Bromage scale. RESULTS: The mean children's and infant's postoperative pain scale of group B was significantly lower than that of group L (p < 0.001). Three patients in group B and seven patients in group L needed additional analgesia after the incision. There was no significant difference between groups in terms of Bromage scores and in both groups the residual motor block was found to be zero at the 150th minutes. CONCLUSION: According to these findings, bupivacaine has an adequate quality of analgesia than levobupivacaine. We suggest that bupivacaine for caudal block at the concentration of 0.25% (0.5 ml/kg) provides an adequate level of analgesia for outpatient circumcision surgery.

RESUMO

Febrile seizures (FS) are the most common cause of seizures in children. The exact etiopathogenesis is unknown but involves factors like genetic predisposition and alterations in the levels of neurotransmitters and some trace elements. The study includes 48 consecutive children with FS, and 55 healthy age matched control subjects. Calcium, magnesium and potassium concentrations in the febrile study group were lower than in the control group (p<0.05). Iron and Gallium levels in the study group were lower than in the control group (p<0.01). Serum Selenium (p<0.001), Zinc (p<0.001) and Strontium (p0.05). The aim of the present prospective analytical case-control study was to determine whether there was any change in element levels in children with FS (Ref. 33).

RESUMO

OBJECTIVE: The purpose of this study was to determine the analgesic efficacy and side-effects of paracetamol and tenoxicam in comparison with placebo in patients with postoperative pain after elective abdominal hysterectomy. MATERIAL AND METHODS: A total of 120 patients were randomly divided into three groups to receive either paracetamol 1 g, tenoxicam 20 mg or placebo intravenously at the end of surgery, and then morphine was administered by a patient-controlled analgesia device postoperatively. RESULTS: Tenoxicam was associated with lower pain scores at the 2nd, 4th, 6th and 24th hour postoperatively. Total morphine consumption was 44.8 +/- 17.4 mg, 64.6 +/- 19.6 mg, 69.2 +/- 22.1 (tenoxicam, paracetamol and placebo group, respectively) and there was a significant difference in the tenoxicam group compared with the other two groups (p < 0.05). Side-effects except for nausea were similar. CONCLUSION: A single dose of 20 mg tenoxicam provided effective analgesia and reduced total morphine consumption in comparison with paracetamol and placebo after abdominal hysterectomy.
