This is a retrospective study of 134 patients operated on for solitary brain metastasis at the University Hospital in Uppsala, Sweden between 1963 and 1982. All the patients underwent postoperative radiation therapy. A statistical evaluation of different prognostic factors was made in order to create a prognostic model, a so-called risk profile, to be used for future patients. The most important factors for the making of risk profiles were found to be the "histological diagnosis" followed by the "location" in the brain, then the "state on admission" and the "age" at admission in that declining order. All these variables separately and together, i.e., as risk profiles, were matched against the outcome during survival as Karnofsky's scores and against the length of survival time. The results are shown in a diagram giving the surgeon grounds for his decision-making for or against operation and also for pre-operative information.

Background/objectives: Cardiac rhabdomyoma (CR), the most frequently occurring fetal cardiac tumor, is often an early marker of tuberous sclerosis complex (TSC). This study evaluates outcomes of fetuses with prenatally diagnosed cardiac tumors managed at a single tertiary center.
Methods: Medical records of fetuses diagnosed with cardiac tumors between 2009 and 2024 were retrospectively reviewed.

Ischemic stroke is a worldwide disease with high mortality and morbidity. Kv7/KCNQ channels are key modulators of neuronal excitability and microglia function, and activation of Kv7/KCNQ channels has emerged as a potential therapeutic avenue for ischemic stroke. In the present study, we focused on a new Kv7/KCNQ channel opener QO-83 on the stroke outcomes and its therapeutic potential.

Intracranial solitary fibrous tumors (SFTs) and hemangiopericytomas (HPCs) are rare, aggressive tumors typically found along the dural sinuses. Despite their aggressive nature, complete surgical resection remains the most significant factor in reducing recurrence and improving survival. Here, we present the case of a 32-year-old male patient who presented with a new-onset headache and vertigo.

The parabrachial nucleus (PB), located in the dorsolateral pons, contains primarily glutamatergic neurons that regulate responses to a variety of interoceptive and cutaneous sensory signals. One lateral PB subpopulation expresses the Calca gene, which codes for the neuropeptide calcitonin gene-related peptide (CGRP). These PB neurons relay signals related to threatening stimuli such as hypercarbia, pain, and nausea, yet their inputs and their neurochemical identity are only partially understood.

This paper investigates the potential of artificial intelligence (AI) and machine learning (ML) to enhance the differentiation of cystic lesions in the sellar region, such as pituitary adenomas, Rathke cleft cysts (RCCs) and craniopharyngiomas (CP), through the use of advanced neuroimaging techniques, particularly magnetic resonance imaging (MRI). The goal is to explore how AI-driven models, including convolutional neural networks (CNNs), deep learning, and ensemble methods, can overcome the limitations of traditional diagnostic approaches, providing more accurate and early differentiation of these lesions. The review incorporates findings from critical studies, such as using the Open Access Series of Imaging Studies (OASIS) dataset (Kaggle, San Francisco, USA) for MRI-based brain research, highlighting the significance of statistical rigor and automated segmentation in developing reliable AI models.
