Abstract
OBJECTIVE Craniopharyngiomas are locally invasive neoplasms, and they cause potential lifelong morbidity because of their tendency for local recurrence. Despite advancements in endoscopic techniques, gross-total resection (GTR) of tumors with invasion or adhesion to important surrounding anatomical structures is extremely difficult. The authors present a single-center study that evaluated the impact of the endoscopic endonasal approach (EEA) on the surgical outcomes of pediatric craniopharyngiomas, the factors affecting the resection rate, and recurrence. METHODS A total of 44 pediatric patients (age ≤ 18 years) who were treated via the EEA for craniopharyngioma from August 1997 to June 2022, as well as their 53 operations, were included in this study. The preoperative radiological configuration and surgical data of these cases were assessed. Also, preoperative and postoperative clinical (endocrinologic, neurological, and ophthalmological), hypothalamic, physical and social development, and neurocognitive assessment data were described. RESULTS In total, 37 cases (69.8%) had no history of operation beforehand. The most common symptoms at presentation were endocrine disturbances (98.1%), headache without vomiting (84.3%), and visual disturbance (51%). Cases were classified as infrasellar (1.9%), sellar (32.1%), sellar-suprasellar (52.8%), and suprasellar (13.2%) localization. GTR was achieved in 34/53 cases (64.1%). The rate of GTR was higher in infrasellar and sellar tumors compared with sellar-suprasellar and suprasellar tumors (p = 0.003), and preoperative hypothalamic involvement was associated with lower likelihood of GTR (p = 0.024). Moreover, with experience, the rate of GTR increased (p = 0.037). Postoperative complications, other than endocrine impairment, occurred in 10/53 cases (18.9%). The mean duration of follow-up was 53.57 months. At follow-up, 21/53 (39.6%) cases presented with tumor recurrence. The 5-year progression-free survival (PFS) rate was 48.5%. There was a statistically significant difference between the GTR and other-than-GTR groups in terms of PFS (p < 0.001). According to univariate analysis, smaller tumor (p = 0.017), infrasellar and sellar localization (p = 0.031), and GTR (p < 0.001) were significantly associated with decreased rate of recurrence. Also, there was a statistically significant association between the recurrence rate and adhesion strength of the tumor (p < 0.001). CONCLUSIONS This retrospective cohort study revealed surgical indications for EEA, as well as factors affecting the resection rate, recurrence, and quality of life during the follow-up period of the included cases. The authors believe that GTR should be the goal for craniopharyngioma treatment, but the authors' treatment approach was to provide a balance between radical surgery with maximum safety and adjuvant treatment for long-term disease control.

Abstract
OBJECTIVE Pediatric pituitary adenomas are rare lesions and account for approximately 3% of all supratentorial tumors in children. There is a paucity of reports on endoscopic transsphenoidal surgery in children. The aim of this study was to assess the early/late outcomes of endoscopic pediatric pituitary adenoma surgery at a high-volume tertiary center, as well as to characterize the factors associated with aggressive growth, including the histopathological features. METHODS Between August 1997 and June 2022, a total of 3256 patients underwent endoscopic transsphenoidal surgery for pituitary adenoma at the Department of Neurosurgery and Pituitary Research Center of the Kocaeli University School of Medicine. Of these, 70 (2.1%) pediatric patients (25 males, 45 females) (age ≤18 years) with a pathological diagnosis of pituitary adenoma were retrospectively reviewed. RESULTS The mean age of patients was 15.5 ± 2.3 years. Among the hormone-secreting adenomas, 19 (34.5%) were adrenocorticotrophic hormone secreting, 13 (23.6%) were growth hormone secreting, 19 (34.5%) were prolactin secreting, and 4 (7.2%) were both growth hormone-prolactin secreting. Gross total resection was achieved in 93.3% of nonfunctional tumors. The early/late surgical remission rates for hormone-secreting adenomas were 61.5%/46.1% (mean follow-up: 63.7 ± 49.3 months) for acromegaly, 78.9%/68.4% (47.8 ± 51.0 months) for Cushing disease, 57.8%/31.5% (72.2 ± 59.5 months) for prolactinoma, and 25%/25% (35.2 ± 31.4 months) for growth hormone-prolactin-secreting adenomas. Five sparsely granulated corticotroph tumors, 5 sparsely granulated somatotroph tumors, and 11 densely granulated lactotroph tumors were classified as aggressive histopathological subtypes. CONCLUSIONS The unique characteristics of the pediatric population and the aggressiveness of the disease in this population pose considerable therapeutic challenges. To increase treatment success, current adjuvant therapies that are appropriate for the morphological and biological characteristics of the tumor are required in addition to surgical treatment.

Abstract
OBJECTIVE The mortality incidence of endometrial carcinomas (ECs) has increased in recent years. Therefore, recent studies have focused on the cellular and microenvironmental properties of ECs. Tumor-infiltrating lymphocytes (TILs), a component of the microenvironment, have been found to be associated with the prognosis in many tumors. Although TILs were mostly evaluated by immunohistochemical studies in ECs, in our study, the evaluation was done with a light microscope as a practical approach, and we aimed to determine the prognostic importance of TILs in endometrioid ECs. MATERIAL AND METHOD 104 patients were included in the study. TILs in the stromal area (sTILs) were evaluated on hematoxylin and eosin (HE) stained-sections at X200 objective. The presence of TILs was evaluated as follows; 0-10% as low, 20-40% as moderate, and 50-90% as intense. Then TILs were grouped as low and high. RESULTS Tumors with high TILs were more prone to have FIGO (International Federation of Gynecology and Obstetrics) grade 1 tumors, low nuclear grade, early pathological stage, smaller size, no lymphovascular invasion, myometrial invasion below 50%, and no cervical involvement. In the presence of high TILs, the overall survival showed significant increase but no significant correlation was found with disease-free survival. CONCLUSION Interest in the molecular properties of ECs has increased in recent years. TIL, which can be easily evaluated in HE sections, is an important parameter in patient selection for molecular tests and determining the prognosis of patients.

Abstract
OBJECTIVE Ovarian ischemia constitutes 2-3% of all gynecological emergencies. New-generation therapeutic agents need to be discovered, in addition to invasive interventions capable of reducing the risk of potential ovarian ischemia to a minimum and protecting against potential adverse outcomes. AIMS To investigate the effects of amiodarone (AMD) on ischemia-reperfusion-induced oxidative stress and inflammation-induced ovarian damage. METHODS The control group, received intraperitoneal (i.p.) injection of saline solution. The ischemia group (I-Group), was subjected to ischemia-induced injury without drug administration. The ischemia + AMD (50 mg/kg) group was subjected to ischemia injury and also received i.p. 50 mg/kg AMD prior to induction of ovarian ischemia. The ischemia-reperfusion (I/R group) was exposed to ischemia and reperfusion-induced injury without drug administration. The I/R + AMD (50 mg/kg) group underwent I/R injury together with i.p. administration of 50 mg/kg AMD prior to induction of ovarian I/R. The Sham + AMD group received intraperitoneal (i.p.) injection of 50 mg/kg AMD alone. In this study performed thiobarbituric acid reactive substances (TBARS), thiol (-SH), interleukin 1 Beta (IL-1β), interleukin 6 (IL-6), toll-like receptor 4 (TLR4) and nuclear factor-kappa B(NF-κβ). RESULTS Increased oxidative stress and inflammation as a result of ovarian I and I/R application activated the cascade. AMD was not sufficient to reduce the oxidative stress and inflammation. TLR4 and NF-kβ, which were up-regulated by triggering oxidative stress and inflammation, were not regressed by the effects of AMD. CONCLUSIONS AMD, used as an antiarrhythmic agent, was found to be insufficient, despite its antioxidant and anti-inflammatory properties, to reduce the experimentally induced ovarian tissue damage.

Abstract
Late diagnosis and treatment of ovarian ischemia can lead to worsening of ischemia, irreversible damage to ovarian functions and infertility. In this process, there is no approved medical treatment that can reduce the negative effects of ischemia and contribute positively to ovarian functions during reperfusion after detorsion. Rats were randomly assigned into one of six groups of eight animals each. The groups were designed as follows: The control group, The ischemia(I) group, The Ischemia + Trimetazidine (I + TMZ) (20 mg/kg) group, and The ischemia-reperfusion group (I/R). The Ischemia-Reperfusion + Trimetazidine (I/R + TMZ) (20 mg/kg) group, and The Sham + Trimetazidine (Sham + TMZ) (20 mg/kg) group. In this study performed thiobarbituric acid reactive substances (TBARS), total thiol (-SH), interleukin 1 beta (IL-1β), interleukin 6 (IL-6), toll-like receptor 4 (TLR4), and nuclear factor-kappa B(NF-κβ). Increased oxidative stress and inflammation were as a result of ovarian I and I/R application. Trimetazidine (TMZ), was sufficient to reduce the oxidative stress and inflammation. TLR4 and NF-κβ, which were upregulated by oxidative stress and inflammation, were regressed by TMZ. TMZ should be considered as a potential therapeutic agent in addition to surgery in the clinical treatment of ovarian torsion.
