Acromegaly is a syndrome of metabolic alterations secondary to increased growth hormone levels from a somatotroph pituitary adenoma. A multidisciplinary approach beginning with surgery, followed by adjuvant radiation or medical therapy for residual disease, is considered standard of care. Several factors affect the likelihood of remission after surgery, but the impact of surgical experience on remission rates has not been adequately assessed. ⋯ We report, in this large single-surgeon review of endoscopically operated acromegaly cases, increased rates of surgical remission and reduced complications with increasing surgeon experience. The overall experience of the treating team in dealing with perioperative and intraoperative factors also contributes to improved outcomes.

Gamma Knife surgery (GKS) is an established treatment option for trigeminal neuralgia (TN). However, the long-term efficacy of GKS for patients with TN has not been well studied. The aim of the study is to evaluate the sequential course of pain control after GKS and analyze the factors associated with the long-term analgesic effect, focusing on radiation dosimetry and neurovascular conflict (NVC) factors. ⋯ Targeting the center of the trigeminal nerve in the area of NVC with GKS is associated with favorable long-term pain control.

Multicenter Study
Histopathological correlation (WHO Classification) of meningiomas and their anatomical localization. Multicenter epidemiological study in Mexico.
To determine the epidemiology of the localization and histological type of meningiomas in the Mexican population and the distribution of the different histological patterns and their relationship to tumor localization and patient demographics. ⋯ There was a correlation between the histology of the 15 histopathological varieties of meningiomas and the predilection site of appearance as well as certain demographic aspects, such as sex. This study lays the foundation for future studies in Mexico on the differentiation and typing of meningiomas regardless of the histological grade to which they belong, as the exact behavior of these tumors, including grade I tumors, remains unknown to date.

A 30-year-old woman experienced nasal stuffiness followed by a progressive headache and reduced visual acuity for 3 weeks. She underwent an endoscopic endonasal transsphenoidal approach for pituitary spindle cell oncocytoma 13 months before the present admission. Magnetic resonance imaging revealed an intrasellar cystic lesion with a suprasellar extension. ⋯ Microscopy revealed mites and fungal hyphae. Cultures from the abscess showed Staphylococcus hyicus, Stenotrophomonas maltophilia, and Aspergillus sp. The patient received a 6-week antibiotic treatment, which completely resolved the clinical symptoms and cleared the magnetic resonance imaging findings.

Gangliformis Intumescentia and Beyond: Antonio Scarpa and His Core Contribution to Neuroanatomy, Neurosurgery, and Otoneurosurgery.
Nearly 250 years ago, Antonio Scarpa became a professor of anatomy and surgery only 2 years after he graduated from the University of Padua. The young lecturer soon became one of the most renowned anatomists in Italy and a director of the Faculty of Medicine at the University of Pavia. He worked in the fields of general surgery and ophthalmology. ⋯ Scarpa's magnum opus was the book Tabulae Neurologicae, in which he described the path of several cranial nerves including the vagus nerve and innervation of the heart. Since his death in 1832, Scarpa's head has been preserved at the University History Museum of the University of Pavia. In this historical vignette, we aim to describe Antonio Scarpa's troubled life and brilliant career, focusing on his core contributions to neuroanatomy, neurosurgery, and otoneurosurgery.
