OBJECTIVES: Endonasal endoscopic transsphenoidal surgery (TSS) and resection of pituitary adenomas is considered to be the gold standard treatment for Cushing's Disease (CD). Even with various recent advances in management, disease persistence and recurrences are common in these patients. The remission rate in the global population after surgery has been reported to vary widely from 64 to 93%. This study aims to determine various clinical, biochemical, radiological and histological factors that correlate with persistence and recurrence in patients with CD...

It is crucial to promote the role of women in surgery, particularly in the field of neurosurgery, which is still predominantly male-dominated. Without recognition and support, these talented and pioneering women may continue to be overlooked, despite their significant contributions to the field. One such remarkable woman is Professor Aimée Redondo, the first female neurosurgeon professor in France. She was born in 1944 during the last years of World War II to immigrant parents from Spain. Thanks to grants and scholarships from the French government, Aimée Redondo was able to continue her education...

BACKGROUND: Flow diversion (FD) for bifurcation aneurysms requires excluding one of the branches from the parent artery, raising concern for ischemic events. Herein, we evaluate thromboembolic events and their relation with covering the origin of the posterior cerebral artery (PCA). METHODS: This retrospective analysis included patients with confirmed basilar and proximal PCA aneurysms treated with FD between 2013 to 2023. Procedures were classified according to the coverage of the origin of the PCA...

OBJECTIVES: The long-term prognosis of elderly patients with moyamoya disease (MMD) is not fully understood and needs to be elucidated. MATERIALS AND METHODS: MMD patients who first visited our institute between 1999 and 2019, were ≥50 years of age, and were followed for ≥ 1 year were retrospectively included. Follow-up data such as stroke and disease progression on magnetic resonance angiography (MRA) were collected from medical records. The surgical outcomes of ischemic patients treated with indirect revascularization were assessed...

BACKGROUND: Management of refractory spasticity symptoms remains a challenging task for clinicians. ITB therapy has emerged as a promising option for treating this condition. This study evaluates the effectiveness of ITB therapy in managing refractory spasticity symptoms. MATERIALS AND METHODS: A retrospective chart review was conducted on 34 patients with refractory spasticity symptoms who underwent ITB therapy at a single institution. The patients' demographics, clinical characteristics, and dosages were recorded...

BACKGROUND: Bone flap resorption is an issue after autologous cranioplasty. Critical temperatures above 50°C generated by power-driven craniotomy tools may lead to thermal osteonecrosis, a possible factor in resorption. This ex vivo study examined whether the tools produced excessive heat resulting in bone flap resorption. METHODS: Using swine scapulae maintained at body temperature, burr holes, straight and curved cuts, and wire-pass holes were made with power-driven craniotomy tools...

BACKGROUND: The potential advantages of exoscopy have been discussed theoretically for a long time. Such a concept holds significance, especially in the specific setting of the posterior cranial fossa (PCF), characterized by complex anatomy and long and narrow surgical corridors with relatively extreme working angles. AIM: We aimed to: 1) analyze the institutional preliminary case-based data on the use of the Robotic 3D Exoscope AEOS Aesculap in three different PCF approaches: retrosigmoid (RSA), midline suboccipital (MSA), and supra cerebellar infratentorial (SIA) via feedbacks was collected using a 20-point questionnaire...

OBJECTIV: To evaluate the risk factors of new osteoporotic vertebral compression fractures (OVCFs) after percutaneous vertebroplasty (PVP). METHODS: From January 2016 to November 2019, patients suffering from OVCFs were retrospectively reviewed. The independent influence factors for new OVCFs after PVP were assessed, from following variables: age, sex, BMI, BMD, history of alcoholism, smoking, hypertension, diabetes, glucocorticoid use, and prior vertebral fractures, the number of initial fractures, mean cement volume, method of puncture, D-type of cement leakage and regular anti-osteoporosis treatment...

OBJECTIVE: Despite the growing acceptance of neuronavigation in the field of neurosurgery, there is limited comparative research, with contradictory results. This study aimed to compare the effectiveness (tumor resection rate and survival) and safety (frequency of neurological complications) of surgery for brain gliomas with or without neuronavigation. METHODS: This retrospective cohort study evaluated data obtained from electronic records of patients who underwent surgery for gliomas at Dr...

BACKGROUND: Epithelioid hemangioendothelioma (EHE) is a rare vascular tumor predominantly arising in soft tissue. We report a rare case of thoracic spinal EHE with pulmonary metastasis. METHODS: Case report and systematic review of spinal EHE. RESULTS: A 36-year-old man presented with bilateral lower extremity weakness, progressive paresthesia, and urinary incontinence. He underwent open surgical resection of the tumor and decompression of the spinal cord, with subsequent improvement in neurological function...

INTRODUCTION: Chronic subdural hematomas are a relatively common condition defined as an abnormal collection of blood and its break down products in the subdural space, usually accompanied by a history of preceding mild head trauma. Surgical management remains the mainstay of treatment. The objective of this study was to assess the surgical treatment outcome of patients operated on for chronic subdural hematoma at University of Gondar Comprehensive Specialized Hospital, Northwest Ethiopia...

OBJECTIVE: This study aimed to investigate the causes of lumboperitoneal (LP) shunt failure and determine risk factors for lumbar catheter fracture. METHODS: We retrospectively investigated 149 patients who underwent LP shunting in our hospital between January 2012 and March 2023. Shunt reconstruction occurred in 22 patients (14.8%). Among these, cause of failure was lumbar catheter fracture in five (22.7%). Patient backgrounds, cause of LP shunt failure, surgical technique factors, and anatomical characteristics were extracted for comparative analysis and risk factors of lumbar catheter fracture were analyzed...

PURPOSE: Hemifacial spasm (HFS) results from vascular compression at the root exit of the facial nerve. Although the underlying etiology has yet to be identified, it has been suggested that congenital vascular anomalies are involved. We have hypothesized common trunk anomaly of the anterior inferior cerebellar artery (AICA) and posterior inferior cerebellar artery (PICA), may play a role in HFS. However, no previous studies have directly compared the incidence of this anomaly between HFS patients and normal subjects...

OBJECT: The aim of this study was at building an effective machine learning model to contribute to the prediction of stroke recurrence in adult stroke patients subjected to moyamoya disease (MMD), while at analyzing the factors for stroke recurrence. METHODS: The data of this retrospective study originated from the database of JiangXi Province Medical Big Data Engineering & Technology Research Center. Moreover, the information of MMD patients admitted to the second affiliated hospital of Nanchang university from January 1st, 2007 to December 31st, 2019 was acquired...

INTRODUCTION: Severe traumatic brain injury (TBI) presentation and late clinical outcomes are usually evaluated by the Glasgow Outcome Scale-Extended (GOS-E), which lacks strong prognostic predictability. Several blood biomarkers have been linked to TBI, such as Tau, GFAP, UCH-L1, S-100B, and NSE. Clinical values of TBI biomarkers have yet to be evaluated in a focused multi-study meta-analysis. We reviewed relevant articles evaluating potential relationships between TBI biomarkers and both early and 6-month outcomes...

Risdiplam is a once-daily oral, survival of motor neuron 2 (SMN2) splicing modifier approved for the treatment of spinal muscular atrophy (SMA). JEWELFISH (NCT03032172) investigated the safety, tolerability, pharmacokinetics (PK), and PK/pharmacodynamic (PD) relationship of risdiplam in non-treatment-naïve patients with SMA. JEWELFISH enrolled adult and pediatric patients (N = 174) with confirmed diagnosis of 5q-autosomal recessive SMA who had previously received treatment with nusinersen (n = 76), onasemnogene abeparvovec (n = 14), olesoxime (n = 71), or were enrolled in the MOONFISH study (NCT02240355) of the splicing modifier RG7800 (n = 13)...

The transorbital approach (TOA) is gaining popularity in skull base surgery scenarios. This approach represents a valuable surgical corridor to access various compartments and safely address several intracranial pathologies, both intradurally and extradurally, including tumors of the olfactory groove in the anterior cranial fossa (ACF), cavernous sinus in the middle cranial fossa (MCF), and the cerebellopontine angle in the posterior cranial fossa (PCF). The TOA exists in many variants, both from the point of view of invasiveness and from that of the entry point to the orbit, corresponding to the four orbital quadrants: the superior eyelid crease (SLC), the precaruncular (PC), the lateral retrocanthal (LRC), and the preseptal lower eyelid (PS)...

Metastases are the most frequent intracranial malignant tumors in adults. While Karnofsky Performance Status (KPS) and Clinical Frailty Scale (CFS) are known to have significant impact on overall survival (OS), temporal muscle thickness (TMT) has been postulated to be a promising new parameter to estimate prognosis. Patients who received a resection of one to three brain metastases in our institution were included. Temporal muscle thickness was measured in preoperative MRI scans according to a standardized protocol...
