RESUMEN

PURPOSE: There is a growing interest in reconstructive urology and female urethroplasty. We aimed to report our experience in ventral-onlay buccal mucosa graft (BMG) urethroplasty supported with Martius flap (MF) in treating female urethral stricture disease. METHODS: We retrospectively evaluated data of 18 female patients (ages 35-78) who were diagnosed with urethral stricture disease and underwent ventral-onlay BMG urethroplasty supported with MF by single surgeon in a tertiary referral centre between February 2019 and October 2022. Detailed history, international prostate symptom score (IPSS), pelvic examination, urine flow rate (rate and pattern), post void residual (PVR), storage and voiding phase urodynamic study, and voiding cystourethrography were recorded. At the last visit; the number of urethral dilatations before urethroplasty, time from urethral dilation to urethroplasty, hospital stay, urethral catheterization time, postoperative IPSS, PVR and uroflowmetry values were recorded. RESULTS: The presenting symptoms were obstructive voiding symptoms in 16 patients. While the mean number of urethral dilatation was 2.11 ± 1.93 (1-7), the mean time from dilatation to urethroplasty was 5.83 ± 5.00 (1-19 months) months. Maximum flow rate increased from 8.36 ± 3.26 ml/sec in preoperative uroflowmetry to 21.45 ± 5.27 ml/sec at the last follow-up (p < 0.001). Post-void residual urine (PVR) decreased from preoperative mean 116.66 ± 105.88 cc to 26.94 ± 22.69 cc postoperatively (p < 0.004). None of the patients developed stricture recurrence, incontinence or vaginal fistula until the last follow-up. The mean follow-up period was 17.28 ± 11.65 (1-35) months. CONCLUSIONS: A ventral-onlay BMG urethroplasty supported with MF represents an effective and reproducible treatment option for FUS in the present study.

RESUMEN

Female urethroplasty provides excellent results with high success rates in the treatment of female urethral stricture (FUS), but sexual functions after urethroplasty is another concern and have not been adequately investigated. We aimed to evaluate changes in the sexual functions of patients undergoing ventral onlay buccal mucosa graft urethroplasty (VOBMGU). We retrospectively evaluated 18 patients who underwent VOBMGU supported with a Martius labial fat pad flap (MLFPF) in our tertiary referral centre, between 2019 and 2021. After excluding patients who were sexually inactive and those with missing postoperative data, 13 patients were included. Surgical outcomes were assessed with uroflowmetry, the American Urological Association symptom score (AUA-SS), and Urogenital Distress Inventory (UDI)-6. Short Form-36 (SF-36) was used to evaluate the quality of life (QoL). Sexual function was assessed using the Female Sexual Function Index (FSFI) both preoperatively and at 6 months following surgery. The median age was 50 (IQR:44-62) years. There was no surgical failure, and none of the patients developed incontinence or stricture recurrence during a median follow-up of 30 (IQR:12-30) months. The median maximum flow rate increased from 9.2 (IQR:5-11.5) to 19 (IQR:17.35-27.10) ml/s (p = 0.001), the median post-void residual (PVR) volume decreased from 80 (IQR:0-205) to 20 (IQR:10-45) ml (p = 0.021), the median AUA-SS decreased from 19 (IQR:14-22) to 6 (IQR:4-8) (p = 0.001), and the median UDI-6 score decreased from 12 (IQR:6.5-16) to 4 (IQR:2-9) (p = 0.008) postoperatively. Bodily pain and general health perception domains and the physical component summary score were significantly improved in the SF-36 (p = 0.015, 0.022, and 0.009, respectively). The median total FSFI score increased from 17.40 (IQR:1.95-23.65) to 22.60 (IQR:5-24.95) postoperatively (p = 0.004). Improvements were observed in all domains (p < 0.05) except the arousal (p = 0.058) and pain (p = 0.104) domains of the FSFI. We concluded that VOBMGU has good early functional results and improves female sexual function.

RESUMEN

Background and Aim: The study aimed to investigate the effectiveness of aspartate aminotransferase (AST), alanine aminotransferase (ALT), and platelet values in predicting intrahepatic cholestasis of pregnancy (ICP) in the first trimester, together with the aspartate aminotransferase/platelet ratio index (APRI) score. Materials and Methods: This study consisted of a patient group diagnosed with ICP (n=49) and a control group (n=62). Laboratory tests of both groups were analyzed retrospectively. Results: The first-trimester APRI score and AST and ALT values were found to be statistically significantly higher than those of the control group. The platelet value was found to be statistically significantly lower in the study group, even though it was within the normal reference range. Conclusion: The first-trimester APRI score was found to be effective in predicting ICP. In addition, the first-trimester AST, ALT, and platelet values were found to be effective in predicting ICP diagnosed in the third trimester even though if not as much as the APRI score.

RESUMEN

OBJECTIVE: The study aimed to investigate the protection of enoxaparin (E) against experimental ischemic (I) and ischemic-reperfusion (I/R) injury in rat ovaries on in vitro fertilization outcomes. METHODS: In total, 56 adult female Sprague-Dawley albino rats were randomly assigned to 6 groups of 8 animals each: Sham, Ischemia, I/R, Sham+E, I+E, and I/R+E. Ischemia groups were subjected to bilateral adnexal torsion for 3 h. In contrast, I/R and I/R+E groups received subsequent detorsion for 3 h. Enoxaparin (0.5 mg/kg s.c.) was administered 30 min prior to ischemia (I+platelet-rich plasma) or reperfusion (I/R+I+platelet-rich plasma). Ovaries were stimulated through intraperitoneal injection of 150-300 internal units IU/kg pregnant mare serum gonadotropin. Anti-Müllerian hormone levels were measured before and after surgery in all groups. RESULTS: When the number of metaphase II oocytes was evaluated, statistically significant differences were observed between the I and I+E (p=0.001) and I/R and I/R+E (p=0.000) groups. When both I and I+E groups and I/R and I/R+E groups were compared, it was found that E application increased the number of fertilized oocytes. The number of embryos on the second day was higher in the I/R+E group than that in the I/R group. Statistically significant differences were found in the number of grade 1 embryos between the I/R and I/R+E groups (p=0.003). In comparing anti-Müllerian hormone values within the group, the highest decrease was observed in the I and I/R groups. CONCLUSION: Enoxaparin effectively minimizes ovarian damage and preserves ovarian reserve following ovarian torsion.

RESUMEN

Local ischemic damage resulting from ovarian torsion is a common cause of decreased follicular activity and infertility. It was aimed to evaluate the effect of granulocyte colony-stimulating factor (G-CSF) protection on in vitro fertilization (IVF) results against experimental ischemic (I) and ischemic-reperfusion (I/R) injury in rat ovaries. The study consisted of 35 adult female Sprague-Dawley albino rats (sham, ischemia, I/R, I + G-CSF, and I/R + G-CSF) randomly assigned to 5 groups, each containing 7 rats. While bilateral adnexal torsion was applied to the ischemia groups for 3 h, detorsion was applied to the reperfusion groups. Intraperitoneal 100 IU/kg G-CSF was administered 30 min prior to ischemia (I + G-CSF) or reperfusion (I/R + G-CSF). After ovulation induction (intraperitoneal 150-300 IU/kg PMSG), the oocytes were collected and IVF was applied. Statistically significant differences were observed between the collected oocyte numbers in I and I + G-CSF, I/R, and I/R + G-CSF groups (P values were P = 0.001 for the I-I + G-SCF groups and P = 0.003 for I/R-IR + G-CSF, respectively). An increase in the number of MII oocytes obtained was observed in the I + G-CSF and I/R + G-CSF groups compared to the I and I/R groups. Grade 1 and grade 2 embryo numbers were statically different between the I/R and I/R + G-CSF groups (P values were P = 0.023 for grade 1 embryos and P = 0.045 for grade 2 embryos, respectively). G-CSF treatment was found to be effective in reducing I- and I/R-induced ovarian damage.

RESUMEN

The aim of the study is to investigate the prevalence of state and trait probable clinical anxiety and their relationship with socio-demographic factors, attitude-behaviour, coping styles and social support level in high-risk pregnant women in the late period of COVID-19 pandemic. The pregnant women followed up in the gynaecological outpatient clinic were evaluated during their admissions. About 191 healthy pregnant women were included in the study. Data were collected using the socio-demographic and pregnancy attitude-behaviour data form, STAI (Spielberger's State-Trait Anxiety Inventory), the Coping Styles Scale Brief Form (Brief-COPE) and the Multidimensional Scale of Perceived Social Support (MSPSS). Our study found that pregnant women had high anxiety levels (STAI-S:37.90 ± 8.88; STAI-T:42.46 ± 7.80) and probable clinical anxiety prevalences (STAI-S:81(42.4%); STAI-T:123(64.4%)) in the late period of the COVID-19 pandemic. The fact that COVID-19 determined the preference of the birth method and the level of knowledge about COVID-19 predicted state probable clinical anxiety. Educational status, concern for COVID-19 transmission to the baby during pregnancy/birth, behavioural disengagement, focussing on and venting emotions predicted trait probable clinical anxiety. Our results have emphasised the factors that should be taken into account and coping styles that may be functional to protect the mental well-being of healthy pregnants.IMPACT STATEMENTWhat is already known on this subject? The COVID-19 pandemic has been shown to increase the symptoms of stress, anxiety and depression of the general population and healthcare workers. There is limited studies about pregnant women.What do the results of this study add? According to our study, we can say that approximately half of the pregnant women in a pandemic need psychiatric evaluation due to probable clinical anxiety. The relationship between anxiety in the pandemic process and birth preference has been shown and coping styles in healthy pregnant women have been investigated for the first time, effective and ineffective coping styles have been shown. In addition, it has been found that the social support of pregnant women is effective in managing the pandemic process.What are the implications of these findings for clinical practice and/or further research? According to our current findings, a multidisciplinary approach in which pregnant women are screened with self-report psychiatry tests and appropriate pregnant women are consulted to psychiatry during pandemic processes will make it easier for obstetricians to manage the patient. Especially strengthening effective coping styles and social support will have a great effect in mental rehabilitation. In this respect, further studies on pregnant women are needed.

RESUMEN

OBJECTIVE: This study aimed to evaluate the effectiveness of fetal left ventricular modified myocardial performance index in predicting adverse perinatal outcomes for intrahepatic cholestasis of pregnancy. METHODS: A cross-sectional study was conducted, including 51 women with intrahepatic cholestasis of pregnancy and 80 healthy controls. Using Doppler ultrasonography, E-wave, A-wave, isovolumetric contraction time, isovolumetric relaxation time, and ejection time were recorded and the left ventricular modified myocardial performance index was measured. RESULTS: Findings showed that the mean left ventricular modified myocardial performance index, isovolumetric contraction time, and isovolumetric relaxation time values were statistically significantly higher while the ejection time and E/A ratios were statistically significantly lower in the intrahepatic cholestasis of pregnancy group than the control group. In the intrahepatic cholestasis of pregnancy group, a statistically significant positive correlation was found between left ventricular modified myocardial performance index and adverse perinatal outcomes in the intrahepatic cholestasis of pregnancy group (r=0.478, p<0.001), while a statistically significant negative correlation was found between the E/A ratio and adverse perinatal outcomes (r=-0.701, p<0.001). CONCLUSIONS: For intrahepatic cholestasis of pregnancy cases, high fetal left ventricular modified myocardial performance index values were an indicator of ventricular dysfunction, and this correlated with negative perinatal outcomes.

RESUMEN

OBJECTIVE: The purpose of this study was to investigate the prevalence of anxiety among high-risk pregnant women in the late period of the coronavirus disease 2019 pandemic and to evaluate the relationship between anxiety levels, attitudes-behaviors, coping styles, and other psychometric parameters. METHODS: Pregnant women who were followed up in our gynecology outpatient clinic were evaluated during their admissions between November 15, 2020 and February 15, 2021. This cross-sectional study analyzes prospectively collected data from a university hospital. Inclusion criteria were those being at risk of pregnancy and between the age of 18 and 45 years, while exclusion criteria were mental retardation and the presence of serious psychiatric illness. The study included 140 participants. Sociodemographic and pregnant attitudes-behaviors data form, State-Trait Anxiety Inventory, Coping Styles Scale Brief Form (Brief-COPE), and Multidimensional Scale of Perceived Social Support were used to collect data. RESULTS: Participants had high anxiety levels (State-STAI: 40.32±9.88; Trait-STAI: 42.71±7.32) and high prevalence of probable clinical anxiety [State-STAI: 84 (60.0%); Trait-STAI: 92 (65.7%)]. The fact concerning the transmission of the coronavirus disease 2019 to the baby during pregnancy/birth, extent to which coronavirus disease 2019 pandemic prevents regular pregnancy checkups, and family subgroup-Multidimensional Scale of Perceived Social Support predicted state probable clinical anxiety. Use of disinfectants predicted trait probable clinical anxiety. Employment status predicted state/trait probable clinical anxiety. The existence of trait probable clinical anxiety was significantly associated with behavioral disengagement and substance use which are considered ineffective coping styles. Participants without trait probable clinical anxiety had significantly more adopted positive reinterpretation, one of emotion-focused coping styles. CONCLUSION: Based on our results, the concern of the transmission of the coronavirus disease 2019 to the babies during pregnancy/birth may be the main factor influencing anxiety among high-risk pregnant women.

RESUMEN

BACKGROUND: Many risk factors for pelvic organ prolapse (POP) have been proposed, and the cause is most likely multifactorial. This study aimed to investigate the effect of toileting behaviors on the natural course of anterior vaginal wall prolapse (AVWP). METHODS: Data on 75 women who underwent surgery for symptomatic AVWP were collected. Patients with grade ≥ II AVWP were included in this study and were divided into two groups according to their voiding and defecation position. The volunteers who voided and defecated in a sitting position comprised Group 1, and those who voided and defecated in a squatting position comprised Group 2. The Colorectal-Anal Impact Questionnaire (CRAIQ), Pelvic Floor Impact Questionnaire (PFIQ), Pelvic Organ Prolapse Impact Questionnaire (POPIQ), Urinary Impact Questionnaire (UIQ) and visual analog scale (VAS) pain scores were used to evaluate the patients' symptoms. RESULTS: Forty-four patients were included in Group 1 (sitting position), and 31 patients were included in Group 2 (squatting position). The groups were similar in terms of BMI, parity, menopause duration, topical estrogen use, comorbidities, the presence of constipation and urinary incontinence, and the pad count for incontinence. The time from initial symptoms to surgery was shorter in Group 2 than in Group 1 12 (3-73) and 24 (2-182) months (p = 0.001), respectively. The PFIQ, POPIQ and POP-related VAS scores were significantly higher in patients who voided and defecated in a squatting position. CONCLUSION: In patients with symptomatic POP, increased IAP while performing the squat position during defecation and voiding may increase the severity of patients' symptoms related to prolapse more than that of sitting position. Therefore, questioning the toileting position of patients with AVWP may help inform management decisions, with changing to a sitting position encouraged.

RESUMEN

OBJECTIVE: Ovarian torsion is a common cause of local ischemic damage, reduced follicular activity and infertility. This study aimed to investigate how well platelet-rich plasma (PRP) protects against experimental ischemic (I) and ischemia-reperfusion (I/R) injury in rat ovaries and its effect on in vitro fertilization (IVF) outcomes. METHOD: Fifty-six adult female Sprague-Dawley albino rats were randomly assigned to six groups of eight animals each: Sham, Ischemia, I/R, Sham + PRP, I + PRP, and I/R + PRP. The remaining eight animals were used to prepare the PRP. The ischemia groups were subjected to bilateral adnexal torsion for 3 h, while the I/R and I/R + PRP groups received subsequent detorsion for 3 h. Intraperitoneal (i.p.) PRP was administered 30 min prior to ischemia (I + PRP) or reperfusion (I/R + PRP). The ovaries were stimulated through an intraperitoneal injection of 150-300 internal units of IU/kg PMSG. After ovulation induction, oocytes were taken from the ovaries, and IVF was performed. RESULTS: The number of MII oocytes reached the highest number with 4.63 ± 0.74 in the S group and had the lowest number with 0.50 ± 0.53 in the I/R group. There were statistically significant differences for the number of embryos obtained on the second day between the I and I + PRP groups and the I/R and I/R + PRP groups (p = 0.000). In comparing anti-Müllerian hormone 1 (AMH1) and AMH2 values within the group, the highest decrease was observed in the I and I/R groups. CONCLUSION: PRP is effective in minimizing ovarian damage and preserving ovarian reserves following ovarian torsion.

RESUMEN

OBJECTIVE: Premature ovarian insufficiency (POI) contributes significantly to female infertility. Cyclophosphamide (CYC has adverse effects on folliculogenesis. Platelet-rich plasma (PRP) is an autologous product rich in many growth factors. We evaluated the protective effect of PRP on in vitro fertilization in female rats with CYC-induced ovarian damage. METHODS: Twenty-eight adult female Sprague-Dawley rats were randomly divided into four groups. Group 1 (control-sodium chloride 0.9%; 1 mL/kg, single-dose intraperitoneal [IP] injection); group 2 (CYC), 75 mg/kg, single-dose IP injection and sodium chloride 0.9% (1 mL/kg, single-dose IP injection); group 3 CYC plus PRP, CYC (75 mg/kg, single-dose and PRP (200 µl, single-dose) IP injection); and group 4 (PRP, 200 µl, single-dose IP injection). RESULTS: In the comparisons in terms of M1 and M2 oocytes, it was observed that the CYC group presented a significantly lower amount than the control, CYC/PRP, and PRP groups. (for M1, p = 0.000, p = 0.029, p = 0.025; for M2, p = 0.009, p = 0.004, p = 0.000, respectively). The number of fertilized oocytes and two-celled good quality embryos was found to be statistically significant between the CYC and control groups, CYC + PRP and PRP groups (p = 0.009, p = 0.001, p = 0.000 for oocytes, respectively. For embryos; p = 0.016, p = 0.002, p = 0.000). CONCLUSION: Platelet-rich plasma can protect the ovarian function against damage caused by CYC, and, in addition, it improves oocyte count and the development of embryos as a result of oocyte stimulation during the IVF procedure.


OBJETIVO: A insuficiência ovariana prematura (POI) contribui significativamente para a infertilidade feminina. A ciclofosfamida (CYC) tem efeitos adversos na foliculogênese. O plasma rico em plaquetas (PRP) é um produto autólogo rico em muitos fatores de crescimento. Avaliamos o efeito protetor do PRP na fertilização in vitro em ratas com lesão ovariana induzida por CYC. MéTODOS: Vinte e oito ratas Sprague-Dawley adultas foram divididas aleatoriamente em quatro grupos. Grupo 1 (controle - cloreto de sódio 0,9%; 1 mL/kg, injeção intraperitoneal [IP] em dose única); grupo 2 (CYC), 75 mg/kg, injeção IP de dose única e cloreto de sódio 0,9% (1 mL/kg, injeção ip de dose única); grupo 3 CYC + PRP, CYC (75 mg/kg, dose única e PRP (200 µl, dose única) injeção IP); e grupo 4 (PRP, 200 µl, injeção IP de dose única). RESULTADOS: Nas comparações em termos de ovócitos M1 e M2, observou-se que o grupo CYC apresentou uma quantidade significativamente menor que os grupos controle, CYC/PRP, e PRP. (Para M1, p = 0,000, p = 0,029, p = 0,025; para M2, p = 0,009, p = 0,004, p = 0,000, respectivamente). O número de oócitos fertilizados e embriões bicelulares de boa qualidade foi considerado estatisticamente significativo entre os grupos CYC e controle, CYC + PRP e grupos PRP (p = 0,009, p = 0,001, p = 0,000 para oócitos, respectivamente. Para embriões, p = 0,016, p = 0,002, p = 0,000). CONCLUSãO: O PRP pode proteger a função ovariana contra os danos causados pelo CYC e, além disso, proporciona melhora na contagem de oócitos e no desenvolvimento de embriões como resultado da estimulação ovariana durante o procedimento de fertilização in vitro.

RESUMEN

This study aimed to evaluate the effects of propofol and dexmedetomidine over different timescales on the IVF outcomes for transvaginal oocyte retrieval (TVOR). Twenty-four rats included in the study were divided into two main groups and three subgroups were subjected to the ovulation induction process. Group 1 was administered propofol (100 mg/kg i.v.) and group 2 were administered dexmedetomidine (25 µg/kg i.p.) The oviduct collection procedure was completed within 15 min for subgroup Pro15min, Dex15min (n = 4), within 16 to 30 min for subgroup Pro30min, Dex30min (n = 4) and within 31 to 60 min for subgroup Pro60min, Dex60min (n = 4) after euthanasia. The total number of oocytes was counted. After in vitro fertilization, the number and quality of embryos were evaluated. The number of pups born were evaluated after embryo transfer. The embryo number, quality and pup count decreased as the administration time for propofol increased (p < 0.05). No statistically significant difference was found between the dexmedetomidine subgroups for embryo number, quality and pup count(p > 0.05). As the exposure time to propofol increased, the number and quality of embryos obtained, and the pup count, decreased. The use of dexmedetomidine had no negative impacts on the number of embryos, their quality or the number of pups.

RESUMEN

SUMMARY OBJECTIVE: This study evaluates the effects of a ketogenic diet on morphology and follicle reserve. METHOD: Sixteen Sprague-Dawley rats were randomized into two groups: standard diet group (n=8) and ketogenic diet group (n=8). Rats were time mated. Dams were permitted to deliver spontaneously. The animals were monitored for the onset of puberty. All the rats were weighed and anesthetized, serum anti-Müllerian hormone level was measured, and the oviducts were removed. The morphological characteristics of follicles were determined and total ovarian volumes were calculated. RESULTS: The mean ovarian volume was statistically significantly lower in the ketogenic diet group compared to the standard diet group (14.41±0.99 mm3 versus 18.89±1.28 mm3) (p=0.000). The mean number of antral follicles was 13.63±1.80 in the standard diet group and 4.462±0.760 in the ketogenic diet group. The mean ovarian weight of the ketogenic diet group was significantly lower than that of the standard diet group (0.42±0.06 g versus 0.815±107 g). The mean anti-Müllerian hormone levels were significantly higher in the standard diet group compared to the ketogenic diet group (1.023±4.75 ng/mL versus 0.69±0.07 ng/mL) (p=0.000). The mean percentage of staining of Ki-67 was 35.28±4.75 in the standard diet group and 16.98±3.33 in the ketogenic diet group (p=0.000). CONCLUSION: Maternal ketogenic diet reduces ovarian follicular reserve in female offspring and has important implications for maintaining reproductive potential at a population level.

RESUMEN

OBJECTIVE: This study evaluates the effects of a ketogenic diet on morphology and follicle reserve. METHOD: Sixteen Sprague-Dawley rats were randomized into two groups: standard diet group (n=8) and ketogenic diet group (n=8). Rats were time mated. Dams were permitted to deliver spontaneously. The animals were monitored for the onset of puberty. All the rats were weighed and anesthetized, serum anti-Müllerian hormone level was measured, and the oviducts were removed. The morphological characteristics of follicles were determined and total ovarian volumes were calculated. RESULTS: The mean ovarian volume was statistically significantly lower in the ketogenic diet group compared to the standard diet group (14.41±0.99 mm3 versus 18.89±1.28 mm3) (p=0.000). The mean number of antral follicles was 13.63±1.80 in the standard diet group and 4.462±0.760 in the ketogenic diet group. The mean ovarian weight of the ketogenic diet group was significantly lower than that of the standard diet group (0.42±0.06 g versus 0.815±107 g). The mean anti-Müllerian hormone levels were significantly higher in the standard diet group compared to the ketogenic diet group (1.023±4.75 ng/mL versus 0.69±0.07 ng/mL) (p=0.000). The mean percentage of staining of Ki-67 was 35.28±4.75 in the standard diet group and 16.98±3.33 in the ketogenic diet group (p=0.000). CONCLUSION: Maternal ketogenic diet reduces ovarian follicular reserve in female offspring and has important implications for maintaining reproductive potential at a population level.

RESUMEN

In this study, we aimed to investigate the association of serum asymmetric dimethylarginine (ADMA) and anti-Müllerian hormone (AMH) levels in primary dysmenorrhea patients. The study employed a cross-sectional design. Eighty-nine female university students with primary dysmenorrhea were included in the study. All patients underwent complete clinical and laboratory investigations, including serum ADMA, AMH levels, pelvic ultrasonography, electrocardiography, and echocardiography. Pearson correlation and linear regression analysis were used to evaluate associations between continuous data. Categorical associations were evaluated using χ(2) test. Correlation analysis between serum ADMA and AMH levels in the study group showed a highly significant positive relationship (Pearson correlation = 0.978, p = 0.01). Our study has shown a significant positive correlation between serum ADMA and AMH levels in primary dysmenorrhea. Serum ADMA levels may have the potential to demonstrate ovarian reserve.

RESUMEN

OBJECTIVE: We aimed to investigate the utility of preoperative neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and lymphocyte count as biomarkers to distinguish malignant from benign ovarian masses. MATERIAL AND METHODS: We retrospectively reviewed the histopathological results of 185 benign and 33 malignant cases following surgery for an initial diagnosis of adnexal mass and confirmed ovarian masses. Age, cancer antigen 125 (CA-125), white blood cell (WBC) count, hemoglobin (Hb), hematocrit (Hct), mean platelet volume (MPV), platelet distribution width (PDW), NLR, PLR, and lymphocyte counts were compared between groups. RESULTS: The significant diagnostic factors to distinguish malignant from benign disease were age (35.5±22 vs. 62±13 years; p<0.001) and CA-125 levels (16.6±21 vs. 98±366 U/mL; p<0.001). No significant difference was observed in WBC count, Hct, Hb, platelet count, PDW, and MPV between groups. To distinguish malignant from benign masses, lymphocyte count (1.29±0.91 vs. 1.80±0.67×10(3) cells/µL, p<0.001), NLR (4.95±5.36 vs. 3.32±2.72, p=0.024), and PLR (203.41±107.84 vs. 160.75±70.84, p<0.001) were identified as markers. The cutoff values were lymphocyte count of >1500 cells/µL (p<0.001), NLR of 3.4732 (p=0.033), PLR of 161.13 (p<0.001), CA-125 of >40 U/mL (p<0.001), and age of >53 years (p<0.001); their respective sensitivity and specificity were 66.7% and 77.8% [area under the curve (AUC), 0.723±0.055], 68.8% and 54.1% (AUC, 0.624±0.058), 81.8% and 50.8% (AUC, 0.683±0.052), 78.8% and 77.8% (AUC, 0.797±0.057), and 81.8% and 82.2% (AUC, 0.888±0.025). Multiple logistic regression analysis revealed cutoff explanatory and accuracy values of 68.2% and 94.9%, respectively, for lymphocyte count, NLR, PLR, CA-125, and age as independent parameters to distinguish malignant from benign ovarian masses. CONCLUSION: In combination with age and CA-125 levels, NLR, PLR, and lymphocyte count may be helpful to preoperatively distinguish malignant from benign ovarian masses.

RESUMEN

BACKGROUND/AIMS: Ovarian torsion is a common cause of local ischemic damage, reduced follicular activity and infertility. Platelet-rich plasma (PRP) contains growth factors with demonstrated cytoprotective properties; so we evaluated PRP efficacy in a rat ischemia/reperfusion (I/R) model. METHODS: Sixty adult female Sprague-Dawley albino rats were randomly assigned to 6 groups of 8 animals each: Sham, Ischemia, I/R, Sham + PRP, I + PRP and I/R + PRP; and the remaining 12 used to prepare PRP. Ischemia groups were subjected to bilateral adnexal torsion for 3 h, while I/R and I/R + PRP groups received subsequent detorsion for 3 h. Intraperitoneal PRP was administered 30 min prior to ischemia (Ischemia + PRP) or reperfusion (I/R + PRP). RESULTS: Total oxidant status (TOS), oxidative stress index (OSI) and total ovarian histopathological scores were higher in Ischemia and I/R groups than in the Sham group (p < 0.05). PRP decreased mean TOS, OSI and histopathological scores in I + PRP and I/R + PRP groups compared to the corresponding Ischemia and I/R groups (p < 0.001). There was a strong correlation between total histopathological score and OSI (r = 0.877, p < 0.001). Peritoneal vascular endothelial growth factor was significantly higher in PRP-treated groups than corresponding untreated groups (p < 0.05). CONCLUSION: PRP is effective for the prevention of ischemia and reperfusion damage in rat ovary.

RESUMEN

OBJECTIVE: This experimental study was designed to evaluate the effect of granulocyte colony-stimulating factor (G-CSF) in ovarian ischemia and ischemia/reperfusion (I/R) injury. STUDY DESIGN: Forty-eight female adult Sprague-Dawley albino rats were divided into six groups as Group 1: sham, Group 2: torsion, Group 3: detorsion, Group 4: sham + G-CSF, Group 5: torsion + G-CSF, and Group 6: detorsion + G-CSF. Except for Groups 1 and 4, all groups underwent a dnexal torsion bilaterally for 3 h. Adnexal detorsion was applied to Groups 3 and 6 for 3 h after a 3-h torsion period. The intraperitoneal injection of G-CSF (100 IU/kg) was administered 30 min previously in Group 4, 5 and 6. At the end of the study process the animals were euthanized and their ovaries were removed for histopathological and biochemical analysis. Total oxidant status (TOS), total antioxidative status and oxidative stress index (OSI) concentrations were determined and compared. Histopathological examination of ovaries was performed for the presence of interstitial edema, congestion, hemorrhage and loss of cohesion to determine tissue damage. RESULTS: In Group 3, 4, 5 and 6, TOS, OSI and total histopathological scores of ovarian tissue were higher than in the sham group (p < 0.05). G-CSF administration decreased mean TOS and OSI levels significantly when compared with the controls (p < 0.001, p < 0.001, respectively). There was a strong correlation between the total histopathological scores of I/R injury and OSI (r = 0.862, p < 0.001). The total histopathological scores for the rats conservatively treated with G-CSF were lower than those of the control groups. CONCLUSION: G-CSF is effective for the prevention of ischemia and ischemia/reperfusion-induced damage in rat ovary.

RESUMEN

The aim of this study was to evaluate the effect of an electromagnetic field (EMF), generated close to the ovaries, on primordial follicles. A total of 16 rats were used in this study. The study group consisted of rats exposed to an EMF in the abdominal region for 15 min/d for 15 days. Both the study and control group were composed of eight rats. After the treatment period of 15 days, the ovaries of the rats were extracted, and sections of ovarian tissue were taken for histological evaluation. The independent samples t test was used to compare the two groups. In the study group, the means of the right and left ovarian follicle numbers were 34.00 ± 10.20 and 36.00 ± 10.53, respectively. The average total ovarian follicle number was 70.00 ± 19.03. In the control group, the means of the right and left ovarian follicle numbers were 78.50 ± 25.98 and 71.75 ± 29.66, respectively, and the average total ovarian follicle number was 150.25 ± 49.53. The comparisons of the means of the right and left ovarian follicle numbers and the means of the total ovarian follicle numbers between the study and control groups indicated that the study group had significantly fewer follicles (p < 0.001, p = 0.011, and p = 0.002, respectively). This study found a significant decrease in the number of ovarian follicles in rats exposed to an EMF. Further clinical studies are needed to reveal the effects of EMFs on ovarian reserve and infertility.
