A comparison of the clinical features of molar pregnancy in adolescents and adults.

Objective: To compare the age-specific clinical features of molar pregnancy and to describe the risk factors associated with this situation. Method: This retrospective case-control study was conducted at the Department of Obstetrics and Gynecology. Tepecik Education and Research Hospital, Izmir, Turkey. The participants included both adolescents (≤ 19 years) and adults with histologically confirmed hydatidiform moles in our institution between January 2015 and January 2022. The interventions and main outcome measures of this study involved evaluating the clinical and ultrasonographic features, as well as the risk factors, associated with molar pregnancies in adolescents. Results: This study of 137 patients with molar pregnancy found that adults had a higher incidence of partial molar pregnancy (20 patients versus seven patients) and lower beta-hCG levels than adolescents (176.890.71 mIU/ml versus 253.734.47 mIU/ml). Adolescents had a higher likelihood of hyperthyroidism (25.4% versus 9.2%). bleeding on admission (4.2% versus 1.51%),. longer hospital stays (5.44 ± 2.73 days versus 3.59 ± 3.08 days). Higher rates of uterine enlargement and postoperative bleeding (15.5% versus 1.5%). Adolescents also required more analgesia (97% versus 89.4%). Conclusions: Adolescents with Gestational trophoblastic diseases (GTD) may present with more severe symptoms compared to adults, which can lead to delayed diagnosis and treatment. Further research is needed to better understand the underlying mechanisms and risk factors for GTDs in this population. Increased awareness and education can help improve recognition and management of GTDs in adolescents and improve their overall health outcomes.

A study to clarify whether sunn pest (Eurygaster integriceps) increases amylase activity in wheat.

There is uncertainty as to whether amylase is injected into wheat kernels by the sunn pest (SP). There are conflicting results in the literature as to whether the amylolytic activity (AA) of insect-damaged wheat is increased. Therefore, the research question of this study is whether amylase is injected into wheat kernels by SP. Two bread wheat cultivars with different levels of SP-damage were used (first year Golia 2.35 % SP damaged kernel ratio [SPDR], second year Golia 3.92 % SPDR and Sagittario 7.8 % SPDR). Sound and SP-damaged wheat (SPDW) kernels were manually separated. In addition, SPDW kernels were divided into four categories according to their infection rates. The AA of these different wheats was determined by using AACC methods 22-05.01 and 56-81.04. In cultivar Golia, the α-amylase activity of the most damaged wheat (C4/4 WGWF) was 9.5 times higher than that of the undamaged wheat. The SP-damaged samples had a lower Falling Number (FN), i.e. higher AA, than the undamaged samples in both cultivars. The FN values of the flour samples prepared from the 100 % SPDW were reduced by up to 40 % compared to the undamaged samples. In conclusion, we clearly found increased amylase activity in SPDW. As the proportion of insect-damaged kernels in the wheat mass increased, the AA of the wheat and its flour also increased, as did the proteolytic activity. Because the AA in some wheats is insufficient for bread-making, SPDW can be blended to sound wheat varieties within certain limits to reduce or reset the use of amylase base additives and reduce bread costs.

Evaluation of placenta and fetal lung using shear wave elastography in gestational diabetes mellitus: An innovative approach.

PURPOSE: This study aims to investigate placental and fetal lung stiffness in pregnant women with and without gestational diabetes, considering the well-established delay in fetal lung maturation associated with gestational diabetes. MATERIALS AND METHODS: This prospective cohort study was conducted at a tertiary center and included pregnant women who underwent a 75-gram oral glucose tolerance test between 24-28 weeks of gestation. Elastography measurements were performed using point shear wave elastography (pSWE). RESULTS: The study included 60 pregnant women diagnosed with gestational diabetes and 60 pregnant women in the control group. SWE velocity of peripheral placenta, central placenta, and lung were higher in the gestational diabetes group compared to the control group. Furthermore, SWE velocity of peripheral placenta, central placenta, and lung were higher in newborns with neonatal respiratory morbidity. Based on the ROC analysis of gestational diabetes patients the AUC for lung SWE velocity was 0.88 (cut-off 12.4 kPa, 95% CI: 0.77-0.99, p<0.001) with a sensitivity of 71.4% and specificity of 95.6% in predicting neonatal respiratory morbidity. CONCLUSION: Fetal placental and lung stiffness increase in fetuses of pregnant women with diabetes. Moreover, higher fetal lung stiffness during the fetal period is associated with increased neonatal respiratory morbidity. Zweck: Diese Studie zielt darauf ab, die Lungensteifheit der Plazenta und des Fötus bei schwangeren Frauen mit und ohne Schwangerschaftsdiabetes zu untersuchen, wobei die bekannte Verzögerung der fetalen Lungenreifung im Zusammenhang mit Schwangerschaftsdiabetes berücksichtigt wird. Materialien und Methoden: Diese prospektive Kohortenstudie wurde an einem tertiären Zentrum durchgeführt und umfasste schwangere Frauen, die sich zwischen der 24. und 28. Schwangerschaftswoche einem oralen 75-Gramm-Glukosetoleranztest unterzogen. Elastographiemessungen wurden mittels Punktscherwellenelastographie (pSWE) durchgeführt. Ergebnisse: Die Studie umfasste 60 schwangere Frauen mit diagnostiziertem Schwangerschaftsdiabetes und 60 schwangere Frauen in der Kontrollgruppe. Die SWE-Geschwindigkeit der peripheren Plazenta, der zentralen Plazenta und der Lunge war in der Gruppe mit Schwangerschaftsdiabetes höher als in der Kontrollgruppe. Darüber hinaus war die SWE-Geschwindigkeit der peripheren Plazenta, der zentralen Plazenta und der Lunge bei Neugeborenen mit neonataler respiratorischer Morbidität höher. Basierend auf der ROC-Analyse von Patienten mit Schwangerschaftsdiabetes betrug die AUC für die Lungen-SWE-Geschwindigkeit 0,88 (Grenzwert 12,4 kPa, 95 %-KI: 0,77-0,99, p < 0,001) mit einer Sensitivität von 71,4 % und einer Spezifität von 95,6 % bei der Vorhersage neonataler Erkrankungen Atemwegsmorbidität. Schlussfolgerung: Die Steifheit der fetalen Plazenta und der Lunge nimmt bei Feten schwangerer Frauen mit Diabetes zu. Darüber hinaus ist eine höhere fetale Lungensteifheit während der Fetalperiode mit einer erhöhten Atemwegsmorbidität bei Neugeborenen verbunden.

Treatment of Posterior Hip Dislocation due to Juvenile Idiopathic Arthritis. Report of Two Cases.

Introduction: Juvenile idiopathic arthritis ( JIA) is a persistent autoimmune-inflammatory disease that affects children younger than 16. Aggressive synovitis of the hip may cause joint destruction, hip protrusion, erosion, pseudosubluxation, dysplasia, and osteoarthritis. Subluxation of the hip had been reported previously. However, dislocation of the hip in JIA is an extremely rare situation, and only two cases have been reported up to date. Reduction of the dislocated hip has to be performed in any way. However, there is no algorithm to be followed for the treatment of hip dislocations caused by JIA. Case Presentation: In this study, we presented two cases of hip dislocation caused by JIA.Case 1: An 11-year-old boy had JIA and chronic recurrent multifocal osteomyelitis (CRMO). X-rays and computed tomography (CT) revealed a posterior dislocation of the left hip. An urgent operation was planned for the reduction of the hip. Avascular necrosis, dysplasia, or erosions were not evident at the last follow-up.Case 2: An 11-year-old girl was referred to the hospital with excessive left hip pain starting 24 h ago. A limited synovectomy with joint irrigation was performed. However, pathological examination of the synovium showed chronic inflammation consistent with JIA. On the post-operative 10th day, the patient was consulted for an increase in hip pain and deformity of the left hip. X-rays and MRI revealed posterior dislocation of the left hip with synovial hypertrophy. An urgent operation was planned. The hip could be reduced under anesthesia with mild traction, and a pelvipedal cast was applied only for 3 weeks. Avascular necrosis, dysplasia, destruction, or erosions were not evident at the last follow-up. Conclusion: For early diagnosed patient reduction under anesthesia and medial soft-tissue contracture release; for late diagnosed patient medial soft-tissue contracture release, capsulotomy and synovectomy were effective to prevent destruction and early degenerative changes of the hip joint for treatment of dislocation caused by JIA.

Surgical management of tethered spinal cord syndrome through biportal endoscopic approach: a novel technical note.

This video article explores a case of tethered cord release through a minimally invasive biportal endoscopic approach. A 24-year-old female with chronic back pain and thigh numbness underwent surgery. The chosen approach involved biportal endoscopic technique, demonstrating precision with minimal bone excision. Preoperative imaging revealed a midline fusion defect at L5 and abnormal conus medullaris termination. The surgical procedure involved one-sided hemilaminectomy, durotomy, and careful filum terminale separation. Postoperatively, radiological exams confirmed success with minimal bone defect. Emphasizing minimal invasiveness, reduced bone excision, and muscle sparing, this technique showcased successful outcomes, enabling the patient's rapid postoperative recovery without complications.

The tortuous course of the anterior ethmoidal artery in the orbit: A cadaveric study.

AIM: The study aimed to define the coursing pattern of the anterior ethmoidal artery in the orbit to minimize complications during endoscopic interventions. MATERIALS AND METHODS: A total of ten formalin-fixed cadaveric halves were included in the study. Orbital regions were shown with a superior approach. The superior rectus and superior oblique muscles, as well as the connective tissue and vessels were removed to observe the path of the anterior ethmoidal artery. Measurements such as the width of the artery, the anterior-posterior length of the U formation, the length of the intraorbital part of the ophthalmic artery, and the distance of the AEA from its opthalmic origin to the anterior ethmoidal foramen were made. RESULTS: Ten of the AEAs originated from the ophthalmic artery. The AEA branches originated from the ophthalmic artery approximately 18.4 mm after the orbital artery entered the orbital, and the mean width of the AEAs was 0.82 mm. In seven of the total anterior ethmoidal arteries, they coursed in the intraethmoidal cavities below the cranial base. The mean distance from the origin of AEAs to the medial wall of the orbit was 4.9 mm. After leaving the ophthalmic artery, seven of the AEAs were coursing forward and turned back ('U' turn formation), which have proximately 1.5 mm in anteroposterior direction. CONCLUSION: The anterior ethmoidal artery is 0.8 mm wide, originates from the distal part of the ophthalmic artery, entering the orbit after a 1.5 mm U-turn.

The Upper Attachment of the Uncinate Process and Anterior Ethmoidal Artery.

OBJECTIVE: Variations in the upper attachment of the uncinate process (UP) are important because they can affect frontal sinus drainage and change the morphology. Functional endoscopic sinus surgery (FESS) is the primary technique used to treat chronic medically refractory rhinosinusitis. Uncinectomy is the basis of FESS technique to obtain the best possible result from surgery. The anterior ethmoidal artery (AEA) enters the nasal cavity through the orbital medial wall (lamina papyracea) may also be affected by the upper attachment of the UP. The aim of this study was to investigate a possible link between UP variations and the course of the AEA. MATERIALS AND METHODS: This retrospective, computed tomography (CT)-based, anatomic study was conducted on 200 healthy adults (100 females and 100 males) by screening bilateral paranasal sinus images. The upper attachment of the UP was classified in 6 types (1-6) based on the Liu classification. The AEA was divided into 4 types (A-D) based on location: anterior to the frontal sinus (A), between the frontal sinus and the middle nasal turbinate (B), and anterior to the posterior ethmoidal cells (C and D). All the CT images were evaluated simultaneously by 2 anatomists and 1 radiologist. RESULTS: Of the total cases (200 right and 200 left side), 48.8% were type 1 UP attachment, 11.0% type 2, 12% type 3, 9% type 4, 18% type 5, and 1.2% type 6. The AEAs were classified as 12.2% type A, 71.8% type B, 15.2% type C, and 0.8% type D. CONCLUSION: The course of the AEA through the nasal cavity was observed to shift anteriorly from the ethmoidal bulla to the frontal sinus in patients with UP attached to the lamina papyracea and middle turbinate. Remarkably, the AEA always coursed anterior from the middle nasal turbinate line.

Comparison of lumbar microdiscectomy and unilateral biportal endoscopic discectomy outcomes: a single-center experience.

OBJECTIVE: Lumbar microdiscectomy (LMD) is still the gold-standard treatment for lumbar disc herniations with progressive neurological deficits that are refractory to conservative treatment. With improvement of endoscopic systems in recent years, endoscopic discectomy techniques have been developed as an alternative to LMD. The unilateral biportal endoscopic discectomy (UBE) technique is one of these endoscopic techniques, and its popularity has increased in recent years because it does not require high-cost specialized endoscopes, many microsurgical instruments are compatible with this system, and it is similar to LMD in terms of anatomical orientation. This study compared results between LMD and UBE techniques in patients with lumbar disc herniations performed by the same spine surgeons at a single center. METHODS: The data of patients with lumbar disc herniation who were operated on with LMD and UBE techniques were retrospectively reviewed. The data obtained were statistically evaluated. The operative video of one of the patients who underwent UBE was edited for demonstration. RESULTS: Between January 2021 and June 2022, 93 patients were operated on for lumbar disc herniation. LMD was performed in 39 patients, and UBE was performed in 54 patients. There were no significant differences in the complications, recurrence, postoperative back and leg pain, patient satisfaction rates, and quality of life index results of the patients in the two groups. The operation time was shorter in the LMD group. In the UBE group, estimated blood loss was lower and postoperative hospitalization was shorter. CONCLUSIONS: Although LMD is still the gold-standard treatment for lumbar disc herniation, the results of UBE are comparable to those of LMD, and it may be a good alternative for spine surgeons who prefer minimally invasive surgery.

Is there a synergistic relationship between diaphragm and pelvic floor muscles in pregnant women?

OBJECTIVE: The aim of this study is to examine whether there is a synergistic relationship between the diaphragm and pelvic floor muscles (PFM) in pregnant women. MATERIAL AND METHODS: Our study was carried out as a cross-sectional study in primigravid pregnants in the second and third trimesters. Superficial electromyography (EMG), 2D/3D ultrasonography (USG), pulmonary function test (PFT), PERFECT, maximum expiratory pressure (MEP) and inspiratory pressure (MIP) measurements were used to evaluate pelvic floor and diaphragm muscle functions during pregnancy. Mann-Whitney U test was used to show the change in the second and third trimesters, and Spearman correlation was used to determine the relationship. RESULTS: No correlation was found between the EMG data of the PFM and diaphragm, or between the USG data of the PFM and diaphragm in all participants, in the second and third trimesters. In the third trimester of the study, diaphragmatic thickness and levator hiatal area (LHA) decreased and both diaphragm and PFM % MVC EMG parameters increased. In the third trimester, FVC, MIP, MEP decreased, and nonsignificant increase in FEV1, FEV1/FVC and peak ekspiratuar flow(PEF) were detected. A significant correlation was found between pelvic floor levator hiatal area USG and FEV1/FVC in both trimesters (r: 0,577p: 0,004). CONCLUSION: There may be a synergistic relationship between the diaphragm and PFM in pregnant women, the relationship may weaken as pregnancy progresses, and there may be no coactivation relationship between the two muscles. In order to prevent the occurrence of pelvic floor dysfunction during pregnancy and to increase the effect of rehabilitation programs, the relationship between the diaphragm and the PFM should be determined and more studies should be conducted.

The effect of progesterone supplementation in women with threatened miscarriage on fetal fraction in non-invasive prenatal testing: A matched case-control study.

AIM: To evaluate the effect of progesterone use on fetal fraction (FF) in non-invasive prenatal testing (NIPT) due to the threat of first trimester miscarriage. METHODS: This case control study included the pregnant who were referred to our clinic for non-invasive prenatal testing. The patients were categorized into three groups: Pregnant women with vaginal bleeding and using progesterone, pregnant women with vaginal bleeding and not using progesterone, and pregnant women without bleeding. The groups were formed by matching gestational week. Women with multiple pregnancy, BMI (body mass index) ≥25, abnormal fetal karyotype, and chronic disease were excluded from the study. Maternal characteristics, FF of the NIPT were recruited from the computer based medical records. RESULTS: A total of 10,275 NIPT tests were performed during the study period. 3% of the patients (n = 308) were found at risk of miscarriage. 100 patients with a vaginal bleeding and 50 control patients were matched. The median value of the fetal fraction ratio was found to be 6.55 in pregnant women without vaginal bleeding, 7.05 in pregnant women who had vaginal bleeding and using progesterone, and 7.3 in pregnant women who had vaginal bleeding and did not use progesterone. Although the fetal fraction ratio was found to be higher in pregnant women with vaginal bleeding and lower in progesterone users, this situation could not reach the level of statistical significance (p = 0.351). CONCLUSIONS: The fetal fraction rate in maternal blood is not affected in pregnant women who use progesterone due to vaginal bleeding in early gestational weeks.

The Similarities and Differences between Liquid-based and Conventional Methods in Evaluation of Thyroid Fine Needle Aspiration Cytologies.

Aims: Thyroid nodules are one of the most frequent medical issues in endocrinology in our country and around the world. The appropriate evaluation of the nodule is critical in the management of patients. Fine needle aspiration cytology (FNAC) is one of the most accurate tools for evaluating these nodules. Conventional and liquid-based (LB) methods are available for thyroid FNAC. In this paper, we aim to determine the best cytological method for the evaluation of thyroid fine needle aspiration materials. Settings and Design: Fine needle aspiration (FNA) materials obtained and prepared by conventional and LB methods from 310 patients were evaluated. These slides were compared in terms of 12 cytological parameters in a three-tiered system, and the kappa coefficient was calculated. Methods and Material: Two slides were prepared from FNA samples, and the rest of the material was left in protective solution for LB cytology. Surepath was used as a LB technique. Conventional slides (CS) were left to dry in the air and stained with May Grunwald Giemsa. Slides prepared by two different techniques were compared in 12 cytomorphological parameters, and Kappa coefficients and correlations were calculated. Statistical Analysis Used: Kappa statistics. Results: In comparison of LB and CS, the highest kappa coefficient was in chromatin texture (ĸ:0.738) and inflammatory cells (ĸ: 0.482). On other parameters, fair or poor agreement was observed. Conclusions: Although there are some superiorities to LB cytology, co-application of these two methods is more favorable in thyroid fine needle aspiration.

Prespecialist perceptions of three-dimensional heart models in anatomical education.

PURPOSE: This article aims to discuss the use of three-dimensional (3D) printed models of vascular variation cases as an educational tool for undergraduate and postgraduate anatomy students. METHODS: This advanced study involved ten anatomy assistants who were provided with five distinct cases of congenital cardiovascular variations, each accompanied by a computed tomography angiography (CT-A) and 1:1 solid model format. The residents were asked to generate perceptions for both formats and then compare these perceptions based on identifying the variation, defining the structural features, and evaluating relevant educational perspectives. RESULTS: The vascular origin measurement values compared to the statistically evaluated real values of the related cases showed that models were 1:1 identical copies. Qualitative assessment feedback from five stations supported the usefulness of 3D models as educational tools for organ anatomy, simulation of variational structures, and overall medical education and anatomy training. Models showcasing different anatomical variations such as aortic arch with Type 2 pattern, a right-sided aortic arch with Type 2 pattern, an aberrant right subclavian artery, arteria lusoria in thorax, and a left coronary artery originating from pulmonary trunk in an Alcapa type pattern allow for better analysis due to their complex anatomies, thus optimizing the study of variation-specific anatomy. The perception level in the 3D model contained higher points in all of the nine parameters, namely identification of cardiovascular variations, defining the vessel with anomaly, aortic arch branch count and appearance order, feasibility of using it in peers and student education. 3D models received a score 9.1 points, while CT-A images were rated at 4.8 out of 10. CONCLUSION: 3D printed anatomical models of variational cardiovascular anatomy serve as essential components of anatomy training and postgraduate clinical perception by granting demonstrative feedback and a superior comprehension of the visuospatial relationship between the anatomical structures.

The clinical significance of lymphovascular space invasion in patients with low-risk endometrial cancer.

OBJECTIVE: The aim of this study was to assess the effect of lymphovascular space invasion on recurrence and disease-free survival in patients with low-risk endometrial cancer. METHODS: The study included patients with stage 1A, grade 1-2 endometrioid endometrial cancer who underwent a total hysterectomy and bilateral salpingo-oophorectomy with pelvic lymphadenectomy. Independent prognostic predictors of endometrial cancer recurrence were assessed using the Cox regression model. Binary logistic regression analysis was used to identify the predictors of distant recurrence. Kaplan-Meier analysis was used to describe survival curves, and the log-rank test was used to compare the differences in survival curves. RESULTS: A total of 189 patients met the inclusion criteria, of whom 24 (12.7%) had lymphovascular space invasion. The median follow-up time was 60 (3-137) months. Distant recurrence was present in 11 of 22 patients who developed recurrence. Kaplan-Meier survival analysis showed that the 5-year disease-free survival rates of patients with lymphovascular space invasion(+) and lymphovascular space invasion(-) were 62.5 and 91.9%, respectively, which were significantly lower (p<0.001). In multivariate Cox regression analysis, the presence of lymphovascular space invasion (p<0.001) and age ≥60 years (p=0.017) remained as prognostic factors for reduced disease-free survival. In binary logistic regression analysis, only lymphovascular space invasion (adjusted OR=13, 95%CI=1.456-116.092, p=0.022) was a prognostic factor for distant recurrence. CONCLUSION: lymphovascular space invasion is a prognostic risk factor for recurrence and distant metastasis and also a predictor of poorer disease-free survival outcomes in low-risk endometrial cancer.

Diagnostic accuracy of pre-induction cervical elastography, volume, length, and uterocervical angle for the prediction of successful induction of labor with dinoprostone.

PURPOSE: The study's aim is to define among a group of ultrasonographic cervical measurements a candidate parameter predictive of successful of induction of labor in term pregnancies with unfavorable cervix. METHODS: This prospective observational study included 141 pregnant women at term with an unfavorable cervix (Bishop score ≤ 6). All patients underwent clinical and ultrasonographic cervical evaluation before dinoprostone induction. Pre-induction cervical assessments included the Bishop score, cervical length, cervical volume, uterocervical angle, and cervical elastographic parameters. Vaginal delivery (VD) was accepted as successful dinoprostone induction. Multivariate logistic regression was conducted to identify the potential risk factors significantly associated with CS while controlling for possible confounding variables. RESULTS: The vaginal delivery rate was 74% (n = 93) and the cesarean section (CS) rate was 26% (n = 32). Sixteen patients who had a cesarean section due to fetal distress before the active phase of labor were excluded from the study. The mean induction-to-delivery interval was 1176.1 ± 352 (540-2150) for VD and 1359.4 ± 318.4 (780-2020) for CS (p = 0.01). Bishop score was lower in women with cesarean section (p = 0.002). When both groups were compared in terms of delivery type, no difference was found between cervical elastography values, cervical volume, cervical length, and uterocervical angle measurements. Multivariable logistic regression model failed to show significant differences between cervical elastography values, cervical volume, cervical length, and uterocervical angle measurements. CONCLUSION: Cervical length, cervical elastography, cervical volume, and uterocervical angle measurements did not provide a clinically useful prediction of outcomes following labor induction in our study group with unfavorable cervix. Cervical length measurements significantly predicted the time interval from induction to delivery.

¿Afecta la infección asintomática, leve y moderada por Covid-19 en el primer y segundo trimestre los resultados del embarazo?

Objetivo : Determinar los efectos de la infección Covid-19 asintomática, leve y moderada en el primer y segundo trimestres en los resultados del embarazo. Métodos : El estudio se realizó en las gestantes que acudieron al Departamento de Perinatología de la Universidad de Ciencias de la Salud de Izmir entre octubre de 2021 y julio de 2022. Se registraron las mujeres embarazadas que presentaban infección asintomática, leve y moderada por Covid-19 en el 1º y 2º trimestre y se siguió el desarrollo de la gestación. Resultados : Un total de 437 pacientes participaron en el estudio. El número de pacientes asintomáticos, leves y moderados de Covid-19 fue de 142, 157 y 138, respectivamente. Cada grupo se analizó como subgrupo del 1º y 2º trimestre según el momento de la infección por Covid-19. La edad media de las pacientes con Covid-19 moderado era superior a la de las pacientes con Covid-19 leve/asintomático (p=0,021). Se observó que el índice de masa corporal era mayor en las pacientes con Covid-19 moderado que en las pacientes con infección leve/asintomática (p=0,048). El parto pretérmino (entre las semanas 34 y 37) fue significativamente mayor en los casos con infección moderada por Covid-19 (p=0,041). Este aumento ocurrió principalmente en pacientes con infección por Covid-19 en el 2º trimestre. No hubo modificaciones significativas en las tasas de cesárea, trastornos hipertensivos del embarazo, pérdida fetal, retraso del crecimiento intrauterino, colestasis del embarazo y diabetes gestacional. Conclusiones : Los efectos de la infección por Covid-19 al inicio del embarazo (1º y 2º trimestres) siguen siendo objeto de investigación. La infección moderada por Covid-19, especialmente en el 2º trimestre, puede provocar un aumento de la tasa de partos prematuros.

Objectives: To evaluate the effects of asymptomatic, mild and moderate Covid-19 infection in the 1st and 2nd trimesters on pregnancy outcomes. Material and methods: The study was performed among patients who applied to the Perinatology Department of Izmir University of Health Sciences, between October 2021 and July 2022. Pregnant women who had asymptomatic, mild and moderate Covid-19 infection in the 1st and 2nd trimesters were registered and their pregnancy processes were followed. Results: A total of 437 patients participated in the study. The numbers of asymptomatic, mild and moderate Covid-19 patients were 142, 157 and 138, respectively. Each group was analyzed as 1st and 2nd trimester subgroups according to the time of Covid-19 infection. The mean age of patients with moderate Covid-19 was higher than with mild/asymptomatic Covid-19 (p=0.021). Body mass index was found to be higher in patients with moderate Covid-19 compared to patients with mild/asymptomatic infection (p=0.048). Preterm labor (between 34th and 37th weeks) was significantly higher with moderate Covid-19 infection (p=0.041). This significant increase was mainly due to the preterm birth rate in patients with previous Covid-19 infection in the 2nd trimester. There was no significant change in the rates of cesarean section, hypertensive disorders of pregnancy, fetal loss, intrauterine growth restriction, cholestasis of pregnancy and gestational diabetes. Conclusions: The effects of Covid-19 infection in early pregnancy (1st and 2nd trimester) are still the subject of research. Moderate Covid-19 infection, especially in the 2nd trimester, may lead to an increase in the rate of preterm birth.

Has the Covid-19 Pandemic increased the complication rate in patients with acute appendicitis?

AIM: The aim of this study is to compare the numbers of patients, clinical outcomes, and complication rates of acute appendicitis before and after COVID-19 pandemic in our clinic. MATERIAL AND METHOD: This is a retrospective clinical study. Patients of 19 to 88 years of age that underwent emergency surgery with the diagnosis of acute appendicitis at Ankara City Hospital Department of General Surgery between 11 December 2019 and 11 June 2020 were included. The first case of COVID-19 in Turkey was announced on 11 March 2020. We studied the demographics, surgical procedures, and complication rates in 3 months periods before and after the first case was announced. RESULTS: A total number of 462 patients were analyzed between the ages of 19-88, 184 of which (39.8%) were females and 278 were males (60.2%). 253 of these patients were diagnosed with AA and underwent surgery before March 11 whereas 209 patients were diagnosed and treated after March 11. DISCUSSION: There was no statistical difference between the two groups in terms of complication rates before and after the pandemic. Although the rate of open appendectomy was increased after the pandemic, no statistical difference has been found. CONCLUSION: No change was observed in terms of hospital admissions, methods of treatment, complication rates, length of stay before and after the COVID-19 pandemic. KEY WORDS: Acute Appendicitis, Appendectomy, COVID-19.

Protective Effect of Adenosine Triphosphate against 5-Fluorouracil-Induced Oxidative Ovarian Damage in vivo.

OBJECTIVE: The aim of our study was to analyze the effect of ATP on possible ovarian damage of 5-FU in rats. METHODS: The animals were divided to three groups; healthy group (HG), 5-FU alone group (FUG) and ATP+5-FU administered group (AFU). The ATP 4 mg/kg was injected intraperitoneally (IP) into the AFU group. The same volume of saline (0.9% NaCl) as the solvent was administered intraperitoneally to the HG and FUG groups. One hour after administering ATP and solvent, 5-FU 100 mg/kg was injected intraperitoneally to the animals in the AFU and FUG groups. ATP was administered to the animals once a day for 10 days. On the 1st, 3rd and 5th days of 5-FU, one dose (total of 3 doses) was administered. On day 10, the animals were euthanasia with high-dose anaesthesia and ovarian tissues were removed. The removed ovaries were analyzed biochemically andhistopathological. RESULT: ATP significantly suppressed both the increase in MDA and IL-6 levels, and the decrease in tGSH, SOD and CAT levels. Treatment with ATP significantly suppressed the severe vacuolization and primordial follicle degeneration induced by 5-FU in our study. CONCLUSION: ATP was possible to be useful for the treatment of 5-FU-induced ovarian damage.

Thymoquinone ameliorates amikacin induced oxidative damage in rat brain tissue.

We investigated the potential neuroprotective effects of thymoquinone (TQ) on amikacin (AK) induced oxidative damage in rat brain. We used 21 male rats divided randomly into three equal groups. The control group was injected intraperitoneally (i.p.) with 0.5 ml 0.9% aqueous NaCl and given 1 ml 0.9% aqueous NaCl orally. The AK group was administered 1.2 g/kg aqueous AK i.p. as a single dose on the day 3 of the study. The AK + TQ group was given a single 1.2 g/kg dose of AK i.p. on the day 3 of the study plus 40 mg/kg/day TQ by oral gavage daily. Treatment with TQ increased serum ferritin and decreased serum calcium levels significantly. TQ also decreased NADPH oxidase-2, NADPH oxidase-4, and caspase-3 levels. Decreased malondialdehyde (MDA) levels and increased superoxide dismutase (SOD) and catalase (CAT) activities were detected in the AK + TQ group compared to the AK group. TQ administration inhibited lipid peroxide formation and blocked oxidative reactions, which reduced the MDA level and increased SOD and CAT activities induced by AK. Oxidative damage caused by AK was ameliorated by TQ treatment owing to its antioxidative and anti-apoptotic effects. TQ may be a potential therapeutic agent for reducing the severity of AK induced oxidative damage to the brain.

The clinical significance of lymphovascular space invasion in patients with low-risk endometrial cancer

SUMMARY OBJECTIVE: The aim of this study was to assess the effect of lymphovascular space invasion on recurrence and disease-free survival in patients with low-risk endometrial cancer. METHODS: The study included patients with stage 1A, grade 1-2 endometrioid endometrial cancer who underwent a total hysterectomy and bilateral salpingo-oophorectomy with pelvic lymphadenectomy. Independent prognostic predictors of endometrial cancer recurrence were assessed using the Cox regression model. Binary logistic regression analysis was used to identify the predictors of distant recurrence. Kaplan-Meier analysis was used to describe survival curves, and the log-rank test was used to compare the differences in survival curves. RESULTS: A total of 189 patients met the inclusion criteria, of whom 24 (12.7%) had lymphovascular space invasion. The median follow-up time was 60 (3-137) months. Distant recurrence was present in 11 of 22 patients who developed recurrence. Kaplan-Meier survival analysis showed that the 5-year disease-free survival rates of patients with lymphovascular space invasion(+) and lymphovascular space invasion(-) were 62.5 and 91.9%, respectively, which were significantly lower (p<0.001). In multivariate Cox regression analysis, the presence of lymphovascular space invasion (p<0.001) and age ≥60 years (p=0.017) remained as prognostic factors for reduced disease-free survival. In binary logistic regression analysis, only lymphovascular space invasion (adjusted OR=13, 95%CI=1.456-116.092, p=0.022) was a prognostic factor for distant recurrence. CONCLUSION: lymphovascular space invasion is a prognostic risk factor for recurrence and distant metastasis and also a predictor of poorer disease-free survival outcomes in low-risk endometrial cancer.

Does COVID-19 increase the incidence of spontaneous rectus sheath hematoma?

BACKGROUND: The COVID-19 pandemic started to affect Turkey in March 2020. In this study, we retrospectively investigated spontaneous rectus sheath hematoma (S-RSH) in patients with COVID-19 presenting with acute abdominal pain during the ongoing pandemic. METHODS: The demographic characteristics, laboratory findings, length of hospital stay, and treatment processes of COVID-19 cases with S-RSH detected between March and December 2020 were recorded. The rectus sheath hematoma diagnosis of the patients was made using abdominal computed tomography, and the patients were followed up. Low-molecular-weight heparin treatment, which was initiated upon admission, was continued during the follow-up. RESULTS: S-RSH was detected in 13 out of 220 patients with COVID-19 who were referred to general surgery for consultation due to acute abdominal pain. The mean age of these patients was 78±13 years, and the female-to-male ratio was 1.6. Mechanical ven-tilation support was applied to three patients, all of whom were followed up in the intensive care unit. Two patients died for reasons independent of rectus sheath hematoma during their treatment. Among the laboratory findings, the activated partial thromboplastin time (aPTT) values did not deviate from the normal range. While there was no correlation between the international normalized ratio (INR) and aPTT (p>0.01), a significant correlation was found between INR and interleukin-6 (IL-6) (p<0.002). None of the patients required surgical or endovascular interventional radiology procedures. CONCLUSION: In the literature, the incidence of S-RSH in patients presenting with acute abdominal pain is 1.8%. However, in our series, this rate was approximately 3 times higher. Our patients' normal INR and aPTT values suggest that coagulopathy was mostly secondary to endothelial damage. In addition, the significantly higher IL-6 values (p<0.002) indicate the development of vasculitis along with the acute inflammatory process. S-RSH can be more commonly explained the high severity of vasculitis and endothelial damage due to viral infection.
