Background: Gangliogliomas are rare tumors primarily arising from the central nervous system, mostly in the temporal lobes, with brain stem involvement being particularly infrequent. To the best of our knowledge, this is the first reported instance of a brainstem ganglioglioma exhibiting an extension to foramen of Luschka.

Case Presentation: We present a unique case of ganglioglioma of the brainstem.

Purpose: In this study, we aimed to evaluate the effectiveness and safety of UBS (Ultrasonic Bone Scalpel) and HSD (High-speed drill) for performing anterior or posterior decompressions in patients with pathologies in cervical and lumbar regions.

Methods: Between October 2022 and June 2024, 60 patients underwent surgery in which a UBS (Sonopet UST-2001; Stryker Neuro Spine ENT, MI, USA) and High-speed Midas Rex MR8 (Medtronic, Fort Worth, TX, USA) drill was used. Informed consent was obtained from all patients.

Article Synopsis
  • This study investigates the effects of extensive surgical resection on outcomes for patients with wild-type IDH glioblastoma, considering the influence of genetic mutations like TERT and EGFR.
  • The analysis included 41 out of 723 patients who underwent either partial or extensive surgeries from 2014 to 2022, focusing on tumor recurrence-free periods and overall survival rates.
  • Results showed that extensive resection led to longer tumor-free intervals and better quality of life scores, although it did not significantly improve overall survival rates despite the presence of TERT mutations and EGFR amplification.

Introduction: This study aimed to investigate the factors influencing the diagnostic yield of microbiologic diagnosis obtained through percutaneous abdominal abscess drainage procedures. We analyzed the influence of diverse clinical, radiological, and pre-procedural factors on the success of microbiologic diagnosis in this context.

Methodology: A retrospective analysis of patients who underwent percutaneous abdominal abscess drainage was performed to assess the factors affecting the diagnostic yield for microbiologic diagnosis.

Introduction: Hemorrhage is a challenging complication of pelvic surgery. This study aimed to analyze the causes, management, and factors associated with morbidity in patients experiencing major pelvic hemorrhage during complex abdominopelvic surgery.

Methods: Patients who had major intraoperative pelvic hemorrhage during complex abdominopelvic surgery at 11 tertiary referral centers between 1997 and 2017 were included.

Aim: To investigate the anal component of the anogenital Human Papillomavirus (HPV) related disease during surveillance of patients treated for cervical intraepithelial neoplasia (CIN).

Methods: Patients were analyzed within two groups according to the histopathological examination of the cervical biopsies: Low-Grade Squamous Intraepithelial Lesion (LSIL) and High-Grade Squamous Intraepithelial Lesion (HSIL) groups. Anal specimens were also collected in the first-year follow-up visit.

Aim: Data regarding the operative management of presacral tumours present various dilemmas due to their rarity and heterogeneous nature. The aim of this study was to evaluate the management strategy, factors associated with operative morbidity and long-term postoperative outcomes in a large group of patients undergoing surgery for presacral tumours.

Method: This study was designed as a multicentre retrospective cohort study.

Article Synopsis
  • The study aims to evaluate how effective the neutrophil-lymphocyte ratio (NLR) and CRP/albumin ratio (CAR) are in assessing disease severity and predicting outcomes in patients with acute cholecystitis (AC).
  • A total of 186 AC patients were analyzed retrospectively, comparing NLR and CAR scores with established severity scores like MPI and P-POSSUM.
  • The findings suggest that CAR and MPI are significantly associated with moderate to severe disease, with CAR being a useful and simpler alternative for predicting morbidity in AC cases.

Aim: The current standard treatment of locally advanced rectal carcinoma is total mesorectal excision and postoperative adjuvant chemotherapy after neoadjuvant concurrent chemoradiotherapy (NCRT). Many studies have shown that pathological complete response (pCR) is an important prognostic factor for patients receiving NCRT. Many studies have therefore been conducted to increase pCR rates by changing the perioperative treatment strategies.

Background: Supratentorial midline epidural hematoma is rare but challenging in diagnosis and management. Indication for surgery can arise even following hospital admission. Being familiar to the presentation and watching out for direct and indirect signs on axial computed tomography (CT) such as suture diastasis or fracture traversing midline are essential to plan multi-planar CT enabling exact diagnosis including form and mass effect of hematoma.

Aim: To analyze and to compare the factors that influence the recurrence of chronic subdural hematoma (CSDH) among patients treated with subdural non-suction-assisted passive drainage, subgaleal suction-assisted active drainage, and without drainage.

Material And Methods: We retrospectively evaluated 87 surgical patients with a diagnosis of CSDH treated between 2007 and 2018 using patient records from the neurosurgery archive of our faculty. The patients were divided into three groups: drainfree group (group A), subdural passive drainage group (group B), and subgaleal active drainage group (group C).

Objective: To investigate the histopathological effects of a peripheral benzodiazepine receptor agonist (Ro5-4864) on epidural fibrosis (EF) in an experimental study model (post-laminectomy) in rats.

Methods: A total of 32 albino Wistar rats were randomly divided into four equal groups (n = 8). In Group 1, no treatment was applied after laminectomy (control group).

Background: Transsphenoidal endoscopic surgery is the first-line treatment for growth hormone-secreting adenomas.

Objective: To analyse the results of the transsphenoidal endoscopic approach for acromegaly and to determine the predictive factors of remission.

Methods: A single-centre retrospective review was performed in patients who underwent endoscopic transsphenoidal surgery for acromegaly between January 2009 and January 2019.

Background: Currently, the lateral internal sphincterotomy is the treatment of choice for a chronic anal fissure (CAF). However, the length of the internal sphincter incision varies, due to lack of standardization. Insufficient length increases the risk of recurrence.

Objective: We aimed to analyze the clinicopathological findings, treatment approach, and treatmen outcomes in patients diagnosed with phyllodes tumor (PT).

Materials And Methods: The clinicopathological data of 26 patients with PT, who were treated between 2008 and 2019, were retrospectively analyzed.

Results: Mean age was 35.

Aim: To evaluate the clinical characteristics of children who recently underwent decompressive craniectomy (DC) due to elevated intracranial pressure (ICP) correlated to head trauma or other causes, such as ischemic insult.

Material And Methods: Twelve patients aged ≤17 years who underwent DC due to elevated ICP between 2013 and 2018 were included in the study. The clinical status of the participants, radiological characteristics, type and timing of surgery, and outcomes were recorded.

Background: Subacute posttraumatic ascending myelopathy (SPAM) involves the rise in high signal intensity on T2-weighted images ≥4 vertebral segments above the initial injured site, and it usually occurs within the first few weeks after the injury. The pathophysiologic mechanisms of traumatic spinal cord damage are not clearly understood; however, there are some pathophysiologic processes such as arterial thrombosis, venous thrombosis, congestive ischemia, inflammatory or autoimmune reaction, and infection in the form of meningitis or myelitis that could lead to SPAM.

Case Description: We present a case of T7 fracture because of left shoulder gunshot injury and ascending myelopathy up to the C2 vertebra level, which occurred 1 week after the gunshot injury, without pretraumatic cervical injury or syringomyelia.
