Demographic and Clinical Characteristics of Earthquake Victims Presented to the Emergency Department with and without Crush Injury upon the 2023 Kahramanmaras (Turkey) Earthquake.

INTRODUCTION: Earthquakes are sudden-onset natural disasters that are associated with substantial material damage, resulting in the collapse of built environment with a high rate of mortality, injury, and disability. Crush syndrome, which can be seen after devastating earthquakes, can lead to acute kidney injury (AKI) and patients may require amputation, fasciotomy, and dialysis. Supportive treatment has an important role in the prognosis of these patients. STUDY OBJECTIVE: The aim of this study was to investigate the demographic and clinical characteristics of traumatic earthquake survivors admitted to the emergency department (ED) of a hospital, which was close to the earthquake zone but not affected by the earthquake, after the February 6, 2023 Kahramanmaras (Turkey) earthquakes. MATERIALS AND METHODS: This study was conducted by retrospectively analyzing the data of 1,110 traumatized earthquake survivors admitted to the ED of a tertiary care university hospital from February 6th through February 20th, 2023. Age; gender; time of presentation; presence of comorbid diseases; ED triage category; duration of stay under debris; presence of additional trauma; laboratory tests; presence of AKI; presence of crush injury and injury sites; supportive treatment (fluid replacement and intravenous [IV] sodium bicarbonate); need for amputation, dialysis, and fasciotomy; duration of hospitalization; and outcome of ED were evaluated. RESULTS: Of the 1,110 traumatic victims in this study, 55.5% were female patients. The mean age of the patients was 45.94 (SD = 16.7) years; the youngest was 18 years old and the oldest was 95 years old. Crush injury was detected in 18.8% and AKI in 3.0% of the patients. Dialysis, amputation, and fasciotomy were required in 1.6%, 2.8%, and 1.4% of the patients, respectively. In total, 29.2% of patients were hospitalized, including 2.9% admitted to the intensive care unit (ICU) and 26.3% to the relevant ward. In total, 0.3% of the patients included in the study died at ED. CONCLUSION: Post-earthquake patients may present with crush injury, AKI may develop, and fasciotomy, amputation, and dialysis may be needed, so hospitals and EDs should be prepared for natural disasters such as earthquakes.

Hyperthyroidism leads learning and memory impairment possibly via GRIN2B expression alterations.

The hippocampus as an important structure for learning and memory functions contains a high level of thyroid hormone receptors. Although there are numerous studies investigating the effects of thyroid hormones on cognitive dysfunction and psychiatric symptoms, the underlying molecular processes of these disorders have not yet been fully elucidated. In the present study, 24 male adult rats (4 months) were divided into 3 groups: control group, sham group and hyperthyroid group. Hyperthyroid group and sham group were treated with l-thyroxine or saline for 21 days. Each group was exposed to Morris water maze testing (MWMT), measuring their performance in a hidden-platform spatial task. After learning and memory tests, intracardiac blood was taken from the rats for serum thyroxine levels. Following blood collection, the rats were decapitated to isolate hippocampal tissue. GRIN2A, GRIN2B, BDNF, cFOS, Cdk5, cdk5r1 (p35), and cdk5r2 (p39) gene expression were evaluated using quantitative reverse transcriptase-PCR. Serum thyroxine level was found to be higher in hyperthyroid rats than in the control and sham groups. According to our MWMT findings, the memory performance of the hyperthyroid group was significantly impaired compared to the control and sham groups (p < 0.05). In the hippocampus, the GRIN2A gene expression level was decreased in the sham group, and the GRIN2B gene expression level was decreased in the sham and hyperthyroid groups compared to the control group (p < 0.05). There was no significant difference in other genes (p > 0.05). Hyperthyroidism impaired hippocampus-dependent spatial memory. Hyperthyroidism caused decreased level of GRIN2B gene expression in the hippocampus.

Effects of cartoon watching and bubble-blowing during venipuncture on pain, fear, and anxiety in children aged 6-8 years: A randomized experimental study.

PURPOSE: This study aimed to compare the effects of bubble-blowing (active distraction) and cartoon watching (passive distraction) techniques on pain, anxiety, and fear during venipuncture in children aged 6-8 years. DESIGN AND METHODS: This experimental study randomly assigned 56 children aged 6-8 years to cartoon watching or bubble-blowing groups. The child, parent, and researcher assessed pain using the Wong-Baker FACES Pain Rating Scale, anxiety using the Children's State Anxiety Scale, and fear using the Children's Fear Scale. The study data were analyzed using the Chi-square tests and independent Sample t-tests. RESULTS: The groups were similar in clinical and demographic characteristics. The scores on pain, anxiety, and fear during the procedure were lower in the cartoon watching group than in the bubble-blowing group (pain t(47) = 2.638, p = .013; anxiety t(47) = 2.358, p = .023; and fear t(47) = 2.784, p = .008). CONCLUSION: This study revealed that cartoon watching as a passive distraction method was more effective in reducing pain, anxiety, and fear during venipuncture in children aged 6-8 years compared to bubble-blowing as an active distraction method. PRACTICE IMPLICATIONS: The cartoon watching technique, which is affordable, easy to access, and effective (in reducing pain, anxiety, and fear), can be safely used during venipuncture in children aged 6-8 years.

Comparison of Two Scoring Systems in Pediatric Open Globe Injuries.

PURPOSE: The aim of this study is to determine the demographic characteristics of pediatric open globe injuries, evaluate the ocular trauma scores (OTS), and predict the visual outcomes. METHODS: All patients with pediatric open globe injuries who applied to Department of Ophthalmology, Faculty of Medicine, Mersin University between January 2018 and December 2019 were included in this study. Age, gender, type of injury, time of admission, time to surgery, OTS, and pediatric ocular trauma score (POTS) were calculated for each patient. The relation between these findings and final visual acuity (VA) after 12 months of follow-up was examined. RESULTS: Forty-two eyes of 41 patients were included in this study. The most common injuries observed were sharp objects such as knives (23.8%) and stones (23.8%). The wound locations were zone I in 36 patients (85.7%) and zone II in 6 patients (14.3%). The most common concomitant eye pathologies were iris prolapse in 37 (88.1%) and hyphema in 29 (69.1%). The mean original OTS was 77.21 and the mean POTS was 46.78. Association between OTS/POTS and final VA was very good (Kendall Tau-b = 0.665, P < 0.001, Kendall Tau-b = 0.505, P < 0.001, respectively). The level of agreement between the predicted VA for OTS and that for POTS was almost perfect (kappa = 0.8726). CONCLUSIONS: This study shows that the original OTS is still the gold standard in pediatric cases.

Evaluation of Preoperative Anxiety in Turkish Paediatric Patients and Validity and Reliability of the Turkish Modified Yale Preoperative Anxiety Scale.

OBJECTIVE: Preoperative anxiety has been related with postoperative behaviour changes, and it is characterised by subjective feelings. The modified Yale Preoperative Anxiety Scale (mYPAS) is a tool, which indicates preoperative anxiety in children older than 2 years. The objective of this study was to investigate factors affecting the level of preoperative anxiety after conduct validity and reliability of the Turkish version of mYPAS. METHODS: After obtaining approval from the ethics committee, 330 children aged 5-16 years were included in the study. Relationships between possible anxiety factors and anxiety levels were evaluated after validity and interrater reliability of the Turkish version. RESULTS: The intraclass correlation coefficient between the three observers was 0.9949 (95% confidence interval [CI]: 0.9939-0.9958) for the playroom assessments and 0.9952 (95% CI: 0.9942-0.9960) for the operating room assessments. The anxiety level was significantly lower in premedicated patients (p<0.001). There was a negative correlation between age and anxiety level (p<0.001, r=-0.350). CONCLUSION: The Turkish version of mYPAS has high validity and reliability and is suitable for use in the paediatric population of our country. Premedication significantly decreased preoperative anxiety, and younger patients tended to have higher anxiety level. For the 5-12 years age range, the level of anxiety decreased with age. More clinical studies are needed to investigate factors that contribute to preoperative anxiety.

[Investigation of the Relationship Between TNF-α, IL-12A, IL-12B and IFN-γ Gene Polymorphisms and Chronic Hepatitis C]. / TNF-α, IL-12A, IL-12B ve IFN-γ Gen Polimorfizmleri ile Kronik Hepatit C Arasindaki Iliskinin Arastirilmasi.

Hepatitis C virus (HCV) infection is still an important public health problem worldwide. Cytokines play an important role in the prognosis of HCV infections. Polymorphisms in the cytokine genes can affect the gene expression and change the clinical course of the disease. The aim of this study was to determine the relationship between chronic hepatitis C and TNF-α rs1799964 (-1031 T/C), IL-12A rs568408 (3'UTR G/A), IL-12B rs3212227 (3'UTR A/C) and IFN-γ rs2430561 (+874 A/T) gene polymorphisms. A hundred patients with chronic hepatitis C and 100 healthy people as control group were included in the study. Approximately 2 ml peripheral blood was taken from the patient and control groups into tubes with EDTA and genomic DNA was obtained using the DNA isolation kit. Single nucleotide polymorphisms in TNF-α (rs1799964), IL-12A (rs568408), IL-12B (rs3212227) and IFN-γ (rs2430561) genes were investigated by using the real-time polymerase chain reaction (Rt-PCR) method. The data obtained were analyzed in SPSS package program. There was no statistically significant relationship between chronic hepatitis C and TNF-α and IFN-γ polymorphisms in terms of genotype and allele distributions (p> 0.05). However, it was found that the relationship between IL-12A (G/A) and IL-12B (A/C) polymorphisms was significant (p< 0.05). The frequencies of IL-12A GA (OR= 4.828, 95% CI= 1.452-16.046, p= 0.010) and AA genotypes (OR= 4.436, 95% CI= 1.398-14.077, p= 0.011) and A alele (OR= 1.602, 95% CI= 1.020-2.518, p= 0.040) were found to be higher in the patient group. When the relationship between chronic hepatitis C and IL-12B gene polymorphism was examined, it was determined that the frequencies of AC (OR= 2.060, 95% CI= 0.836-5.076, p= 0.116) and CC (OR= 3.020, 95% CI= 1.242-7.345, p= 0.015) genotypes and C allele (OR= 1.750, 95% CI= 1.152-2.659, p= 0.008) were high in the patient group. In addition, TNF-α TC/CC, IL-12A GA/AA, IL-12B AC/CC and IFN-γ TT genotypes were found to be 7.5 times higher in the patient group than the control group (OR= 7.500, 95% CI= 1.532-36.714, p= 0.013). Our results showed that IL-12A (3'UTR G/A) and IL-12B (3'UTR A/C) gene polymorphisms and TNF-α TC/CC, IL-12A GA/AA, IL-12B AC/CC and IFN-γ TT interactions may be effective in the risk of the chronicity of hepatitis C. However, further studies are needed to determine the role of polymorphisms in these cytokine genes in HCV infections.

Relationship Between Final Visual Acuity and Optical Coherence Tomography Findings in Patients with Diabetic Macular Edema Undergoing Anti-VEGF Therapy

Objectives: To identify the prevalence of findings in optical coherence tomography (OCT) sections before intravitreal anti-VEGF treatment in patients with diabetic macular edema (DME), and to evaluate the relationship between these findings and final visual acuity and number of injections. Materials and Methods: This retrospective study included 296 eyes of 191 patients (104 male, 87 female) who started intravitreal ranibizumab treatment after being diagnosed with DME in the retina unit between January 2013 and April 2017 were included the study. Spectral domain OCT findings at the time of presentation such as presence of serous macular detachment (SD), vitreomacular traction (VMT), and epiretinal membrane (ERM) were recorded. In addition, the regularity of the ellipsoid zone (EZ) and inner retinal layers was also studied. Results: The mean central retinal thickness measured in SD-OCT was 449±81 µm before treatment and 350±96 µm after treatment (p<0.001). SD was detected in 155 eyes (52.4%), ERM in 67 eyes (22.6%), and VMT in 9 eyes (3%). Thirty eyes (10.1%) had disorganization of the retinal inner layers (DRIL) and 54 eyes (18.2%) had EZ deterioration. The presence of ERM, EZ irregularity, and DRIL were associated with significantly lower final visual acuity (p<0.0001), while there was no relationship between pre-treatment SD and final visual acuity (p=0.11). Injection number was higher in eyes with SD and ERM compared to those without, but this difference was statistically significant only in the presence of SD (p=0.01 and p=0.59, respectively). There was no difference in injection number according to EZ irregularity or presence of DRIL. Conclusion: The coexistence of SD with DME was associated with increased need for treatment but not with final visual acuity. EZ irregularities, DRIL, and ERM are findings that negatively affect visual acuity.

The value of hematological parameters in acute pancreatitis.

BACKGROUND: Acute pancreatitis (AP) is a common inflammatory disease in the emergency department (ED). This study aims to assess the role of CRP and hematologic parameters in mild/severe AP patients and biliary/nonbiliary AP at the time of admission to the ED. METHODS: 168 patients who were diagnosed as AP in the ED, and as a control group, 100 patients were included in this study. At the time of application to the ED, the demographic information (age, sex) and the amylase, lipase, CRP, hematological parameters (WBC, MPV, RDW, PLT, NLR) of all patients and the control group were recorded and compared. According to the etiology of the patients, the patients were divided into biliary and nonbilary AP groups and according to the severity, they were divided into mild and severe AP groups, then, the same parameters were evaluated. RESULTS: Significant differences were found out between WBC, CRP, NLR, MPV and PLT values between patient and the control group (p<0.001). The length of hospitalization and the parameters were not significant between the biliary and the nonbiliary group. Ranson and APACHE II scores were correlated with WBC, CRP and NLR. There was a statistically significant difference between the mild and severe AP groups in terms of duration of the hospital stay, CRP, WBC and NLR values (p=0.003 for CRP, p<0.001 for the others). In severe AP, the cut-off value of NLR was found to be 8.05, sensitivity %93.48, specificity %86.89 and AUC 0.937 (p<0.001). CONCLUSION: The use of parameters, such as WBC, CRP, and NLR, in combination with other diagnostic and prognostic tools in emergency service can provide convenience to clinicians at the time of admission and prognosis.

GDF9 and BMP15 Expressions and Fine Structure Changes During Folliculogenesis in Polycystic Ovary Syndrome.

BACKGROUND: Polycystic ovary syndrome is the most frequently seen endocrine disorder in women of reproductive age with a prevalence of about 10%. AIMS: To investigate the efficiency of growth differentiation factor 9 and bone morphogenetic protein 15 during folliculogenesis in a dehydroepiandrosterone-induced mouse Polycystic ovary syndrome model. STUDY DESIGN: Animal experimentation. METHODS: Mice were divided into 3 groups: control, vehicle and Polycystic ovary syndrome. Polycystic ovary syndrome model mice were developed by the injection of dehydroepiandrosterone dissolved in 0.1 mL of sesame oil. Ovarian tissues were examined for growth differentiation factor 9 and bone morphogenetic protein 15 using immunofluorescent labelling and electron microscopic examinations. RESULTS: The immunoreactivity of growth differentiation factor 9 and bone morphogenetic protein 15 proteins decreased (p<0.05) in the Polycystic ovary syndrome group (27.73±8.43 and 24.85±7.03, respectively) compared with the control group (33.72±11.22 and 31.12±11.05, respectively) and vehicle group (33.95±10.75 and 29.99±10.72, respectively). Apoptotic changes were observed in granulosa cells, lipid vacuoles increased in Theca cells and thickening and irregularities were noted in the basal lamina of granulosa cells. An increased electron density in the zona pellucida in some of the multilaminar primary and secondary follicles in the Polycystic ovary syndrome model was also observed at the ultrastructural level. CONCLUSION: These results suggest that the decrease in the growth differentiation factor 9 and bone morphogenetic protein 15 expression initiated at the primary follicle stage effect the follicle development and zona pellucida structure and may cause subfertility or infertility in Polycystic ovary syndrome.
