Protective and/or therapeutic effects of berberine in a model of premature ovarian failure induced by cyclophosphamide in rats.

Objective: We conducted a biochemical and histological evaluation of whether berberine has a protective and/or therapeutic effect in a cyclophosphamide-induced premature ovarian failure (POF) model. Materials and Methods: We divided 28 Wistar albino female rats into 4 groups [control group, POF group, cyclophosphamide (CP)+berberine (Bb) group, and POF+Bb group]. The POF model was established by intraperitoneal administration of 50 mg/kg CP on day 1 followed by 8 mg/kg/day CP dissolved in saline for the following 14 days. The CP+Bb group received Bb concurrently for two weeks with CP. The POF+Bb group received berberine for two weeks following the completion of CP administration. Left ovaries were used for histopathological evaluation and right ovaries were used for biochemical analysis [tumor necrosis factor-alpha (TNF-α), interleukin (IL)-1, IL-6 levels in tissue]. Results: Ovarian damage scoring was significantly higher in the POF group than in the other groups (p<0.005). In the POF group, primordial and primary follicle counts were the lowest, while secondary and corpus luteum counts were the highest (p<0.005). There was no significant difference between the other groups. The POF group had significantly elevated levels of TNF-α, IL-1, and IL-6 in the biochemistry results (p<0.005). Conclusion: We demonstrated that berberine could be effective in the protection and treatment of POF by reducing proinflammatory cytokines. We believe that our study can make a considerable contribution to the literature in terms of POF protection and/or treatment.

Existence of SARS-Cov-2 in the Peritoneal Fluid.

OBJECTIVE: To determine the existence of SARS-CoV-2 in the peritoneal fluid to assess the risk of exposure through surgical smoke and aerosolization threatening healthcare workers during abdominal surgery. BACKGROUND: SARS-CoV-2 is a respiratory virus and possible ways of viral transmission are respiratory droplets, close contact, and fecal-oral route. Surgeries pose risk for healthcare workers due to the close contact with patients. Aerosolized particles may be inhaled via the leaked CO2 during laparoscopic procedures and surgical smoke produced by electrocautery. METHODS: All the data of 8 patients, who were tested positive for COVID-19, were collected between August 31, 2020 and April 30, 2021. Recorded clinicopathologic data included age, symptoms, radiological and laboratory findings, antiviral treatment before surgery, type of surgery and existence of the virus in the peritoneal fluid. Nasopharyngeal swab RT-PCR was used for the diagnosis. COVID-19 existence in the peritoneal fluid was determined by RT-PCR test as well. RESULTS: All 8 COVID-19 positive patients were pregnant, and surgeries were cesarean sections. 1 of the 8 patients was febrile during surgery. Also only 1 patient had pulmonary radiological findings specifically indicating COVID-19 infection. Laboratory findings were as follows: 4 of 8 had lymphopenia and all had elevated D-dimer levels. Peritoneal and amniotic fluid samples of all patients were negative for SARS-CoV-2. CONCLUSION: SARS-CoV-2 exposure due to aerosolization or surgical fumes does not seem to be likely, provided the necessary precautions are taken.

OBJETIVO: Determinar a existência de SARS-CoV-2 no fluido peritoneal para avaliar o risco de exposição através da fumaça cirúrgica e aerossolização que ameaçam os profissionais de saúde durante a cirurgia abdominal. CONTEXTO: O SARS-CoV-2 é um vírus respiratório e as possíveis formas de transmissão viral são gotículas respiratórias, contato próximo e rota fecal-oral. As cirurgias representam risco para os profissionais de saúde devido ao contato próximo com os pacientes. As partículas aerossolizadas podem ser inaladas através do CO2 vazado durante os procedimentos laparoscópicos e a fumaça cirúrgica produzida pela eletrocauterização. MéTODOS: Todos os dados de 8 pacientes, que foram testados positivos para COVID-19, foram coletados entre 31 de agosto de 2020 e 30 de abril de 2021. Dados clinicopatológicos registrados incluíam idade, sintomas, achados radiológicos e laboratoriais, tratamento antiviral antes da cirurgia, tipo de cirurgia e existência do vírus no fluido peritoneal. O diagnóstico foi feito através do swab nasofaríngeo RT-PCR. A existência de COVID-19 no fluido peritoneal foi determinada pelo teste de RT-PCR também. RESULTADOS: Todas as 8 pacientes positivas para COVID-19 estavam grávidas, e as cirurgias eram cesarianas. 1 das 8 pacientes estava com febre durante a cirurgia. Também apenas 1 paciente tinha achados radiológicos pulmonares especificamente indicando infecção por COVID-19. Os achados laboratoriais foram os seguintes: 4 de 8 tinham linfopenia e todas apresentavam níveis elevados de D-dímero. Amostras de fluido peritoneal e líquido amniótico de todas as pacientes foram negativas para SARS-CoV-2. CONCLUSãO: A exposição ao SARS-CoV-2 devido à aerossolização ou fumaças cirúrgicas não parece ser provável, desde que sejam tomadas as precauções necessárias.

Platelet to lymphocyte and neutrophil to lymphocyte ratios in endometrial pathologies.

OBJECTIVES: Aim of this study was to evaluate the relationship between platelet to lymphocyte ratio (PLR), neutrophil to lymphocyte ratio (NLR), and endometrial pathologies. MATERIAL AND METHODS: The database of our institution was reviewed. Cases with endometrial pathology including endometrial cancer (EC), endometrial hyperplasia with atypia and without atypia, normal endometrial findings, between January 2015 to January 2020, were collected. Their CBC results and clinicopathologic data were determined. The relation between the platelet-lymphocyte ratio (PLR), neutrophil-lymphocyte ratio (NLR), and endometrial pathologies was evaluated. RESULTS: NLR was significantly higher in patients with endometrial cancer compared to other endometrial pathologies including endometrial hyperplasia with and without atypia and patients with normal endometrial findings. NLR cut-off value was determined 3.55 to discriminate cancer among other endometrial pathologies. PLR had not a significant difference between the endometrial pathologies. CONCLUSION: NLR seems to be an effective and simple marker to discriminate endometrial cancer among endometrial pathologies by contrast with PLR.

Effect of mucinous differentiation in endometrioid type endometrial cancers on prognosis.

OBJECTIVES: To evaluate the influence of mucinous differentiation in endometrioid endometrial cancer regarding spread and prognosis. MATERIAL AND METHODS: Endometrioid endometrial cancer cases between 2015 and 2020 were collected retrospectively and divided into two groups according to the cytoplasmic mucin including. Prognostic factors and cancer spread related parameters were evaluated. RESULTS: A total of 219 patients were enrolled in this study. One hundred twenty-two (55.7%) were endometrioid and 97 (44.3%) were in the mucinous differentiated endometrioid catagory. Age was similar between the groups (59.3 vs 58.7, p = 0.62), however, grade 3 lesions were more frequent in endometrioid type endometrial cancer (8.7% vs 1.4%, p < 0.01). Poor prognostic factors including myometrial invasion, lymphovascular space invasion (LVSI), lymph node metastases, peritoneal cytology, endocervical involvement, and stage were not significantly different between groups (p = 0.23, p = 0.49, p = 0.40, p = 0.15, p = 0.17, p = 0.55). The median overall survival time of endometrioid and mucinous differentiated endometrioid type endometrial cancer patients was determined 88.5 and 96.8 months, respectively (p = 0.46). CONCLUSIONS: Mucinous differentiation in the endometrioid type of endometrial cancer does not seem to affect the prognosis in endometrioid endometrial cancer patients.

Measures against COVID-19 pandemic - a single tertiary center experience.

This paper reports the measures taken to manage the impact of the COVID-19 pandemic on O&G services in a tertiary referal centre and their outcomes. All the patients included in this study received inpatient treatment and underwent surgery between March 10 2020 and end of June 2020, including obstetric or gynaecologic cases combined. Data including age, diagnosis, operation, duration of preoperative and postoperative hospital stay, COVID-19 status were recorded. COVID-19 status of the patients was diagnosed with a nasopharyngeal swab test. Thirty-seven (20%) of 177 operations were performed because of gynaecologic reasons. The rest of them were caesarean sections (C/S). In gynaecologic cases, 22 (59%) of 37 were emergent operations, nine (24%) cases were oncologic and six (16%) cases were elective gynaecological surgeries. On the other hand, 43 (30%) of 140 patients, who underwent caesarean sections, were urgent surgeries. The rest were elective and planned caesarean sections. Only five patients (2.8%) who had undergone caesarean sections were tested positive for COVID-19. No COVID-19 transmission to staff was recorded in this period. Measures against the COVID-19 pandemic must be multidisciplinary and is crucial to prevent the spread of the disease to staff in close contact.Impact StatementWhat is already known on this subject? COVID-19 pandemic has been a crucial health problem worldwide. Healthcare workers work intensely to protect people from the pandemic. It is especially important to protect healthcare professionals and hospitalized patients from virus transmission. Therefore, utilization of personal protective equipment such as masks, gloves and goggles is obligatory, and hygiene rules such as sanitization of hands are strictly followed.What the results of this study add? This study adds the experience and success of a tertiary centre regarding the measure against COVID-19 to the literature. No viral transmission was detected to healthcare workers and other patients from COVID-19 patients. Hence, measures that mentioned in the present study should be an example to other centres for protection against pandemic.What the implications are of these findings for clinical practice and/or further research? As mentioned above, measures that are explained in the present study should be an example to other centres for protection against the pandemic. Further larger size clinical studies are needed to prove the beneficial effect of the measures that still used against pandemic.

Evaluation of Epithelioid Trophoblastic Tumor in the Light of Literature.

Epithelioid trophoblastic tumors (ETTs) are extremely rare gestational trophoblastic neoplasia and a subtype of the placental site trophoblastic tumors (PSTTs). To our knowledge, there have been only 110 patients diagnosed with the ETT. ETT is generally seen in the reproductive period, following term pregnancy. Generally, as in PSTT, ß-HCG levels are normal or slightly elevated. The most common complaint is abnormal vaginal bleeding. At the time of diagnosis, findings of metastasis can be seen in 50% of the cases. Transvaginal ultrasonography (TV-USG) and computed tomography (CT) are used for imaging in the literature. Surgical treatment and follow-up are sufficient in the early stages. We present a case of a 37-year-old ETT patient who suffered from irregular vaginal bleeding.

Cervical dysplasia after renal transplantation: A retrospective cohort study.

OBJECTIVE: Since the first days of organ transplantation, it has been accepted that solid transplant recipients have a high risk of developing cancer. Chronic immunosuppression and environmental factors play a role in cancer development in recipients. In the present study, we tried to evaluate the cumulative incidence of cervical dysplasia after renal transplantation, risk factors for disease development, and the time until high-grade dysplasia occurred. MATERIALS AND METHODS: A total of 50 patients with renal transplantation who presented for gynecologic follow-up was included in the study. The medical records of the patients were reviewed until the last clinical visit, their demographic characteristics, transplant history, gynecologic history, and gynecologic examination results (cervical cytology and histology reports) were reviewed. RESULTS: Of the 50 women in the study population, 29 (58%; 95% confidence interval: 8.8-15.9) developed cervical dysplasia after the first transplant at a median follow-up of 7.8 (range: 4.6-12.9) years. Twenty-one women with benign cervical cytology before transplantation had evidence of low-grade intraepithelial lesions + after transplant (47% of these were within 2 years after transplant). During the follow-up, 8 women (18.2%) were diagnosed as having high-grade intraepithelial lesions + (within 5 years after transplantation). CONCLUSION: Renal transplant patients were found to have higher abnormal cervical cytology and histology rates than the normal population.

Octreotide protects ovary against ischemia-reperfusion injury in rats: Evaluation of histological and biochemical parameters.

AIM: This study investigated the efficacy of octreotide for prevention of ischemia-reperfusion injury in rat ovary. METHODS: Thirty-two adult female rats were included. Rats were divided into five groups: in the sham group, the abdominal wall was only opened and closed; in the torsion group, ischemia was induced for 3 h using a torsion model involving atraumatic vascular clips; in the torsion/octreotide group, rats were given 100 µg/kg i.p. octreotide 30 min before torsion was induced; in the torsion/detorsion group, rats underwent 3 h ischemia-3 h reperfusion; in the torsion/detorsion/octreotide group, rats underwent 3 h ischemia followed by 100 µg/kg octreotide i.p. 30 min prior to 3 h reperfusion. Ovarian tissue damage was scored on histopathology. Ovarian tissue malondialdehyde and plasma pentraxin 3 were measured biochemically. RESULTS: In comparison with the sham group, both the torsion and torsion/detorsion groups had significantly higher scores for follicular degeneration, vascular congestion, edema, hemorrhage and leukocyte infiltration. Octreotide significantly decreased these scores in both groups. Ovarian malondialdehyde and plasma pentraxin 3 were significantly higher both in the torsion and torsion/detorsion groups compared with the sham group. Octreotide also decreased these levels significantly both in the torsion/octreotide and torsion/detorsion/octreotide groups. CONCLUSION: Octreotide ameliorated the potential side-effects of ovarian ischemia-reperfusion injury in a rat model.
