Awake surgery for glioma resection during pregnancy: a systematic review.

Brain tumors are rarely present during pregnancy. However, they can severely impact the fetus and mother's well-being due to a complex interaction of disease and physiological factors. Moreover, awake surgery for gliomas has been scarcely reported during this life stage, and the nuances and techniques merit further investigation. Herein, we performed a systematic review of the literature about awake surgery for glioma resection during pregnancy. A total of six patients with a median age of 30.5 years (interquartile range: 40-27) were analyzed. Awake surgery was performed in the third trimester in 50% of patients (median time: 24.5 weeks) without reported intraoperative complications. Conscious sedation was achieved by remifentanil and propofol infusion in 67% of cases, and intraoperative fetal heart monitoring was utilized in 83% of cases. Most studies revealed good clinical maternal-fetal outcomes at follow-up; however, long-term safety effects remain undetermined and warrant further research. In conclusion, awake surgery for glioma resection under a multidisciplinary approach can be a reasonable treatment option for select patients during pregnancy.

Awake Craniotomy for Resection of Diffuse Astrocytoma During Pregnancy: A Case Report.

Brain tumors rarely present during pregnancy; however, a life-threatening interaction may develop between maternal and disease factors. Moreover, awake surgery has been an infrequent treatment option during this life stage. We contribute to this knowledge gap by presenting the case of a 33-year-old woman who developed tonic-clonic seizures during the 18th week of pregnancy due to a neoplastic lesion near the left motor area. A multidisciplinary team performed an awake craniotomy for tumor resection and the histopathological examination revealed a diffuse astrocytoma. On the follow-up, radiotherapy was administered and the patient delivered a healthy newborn at week 37.

Neurosurgical aspects and clinical outcomes on the treatment of Cushing disease in pediatric patients: Case series and literature review.

Background: Cushing disease (CD) is a state of hypercortisolism caused by an adrenocorticotropic hormone-(ACTH) producing pituitary adenoma which rarely occurs in pediatric patients. The outstanding features are weight gain and growth retardation. However, the insidious onset and rarity of the disease in children and adolescents often result in delayed diagnosis. Case Description: We present five patients <14 years of age who underwent neurosurgical treatment for CD at the Department of Neurosurgery of a public referral hospital in Lima, Peru. Age at diagnosis ranged from 5.5 to 12.5 years with a history of disease from 9 months to 3.5 years of moderate to severe stunting and obesity, among other features of Cushing syndrome (CS). Although biochemical tests and cerebral imaging were crucial for the diagnosis, confirmation was made by bilateral petrosal sinuous sampling. Regarding treatment, three patients underwent transcranial surgery, one patient underwent endoscopic transsphenoidal surgery, and one patient underwent microscopic transsphenoidal surgery. None of the patients underwent radiotherapy or pharmacological treatment. Only one patient had a recurrence and achieved remission until an endoscopic transsphenoidal approach was performed. Short- and long-term endocrinologic follow-up is also described in detail. Conclusion: CD is a heterogeneous disorder that requires multidisciplinary diagnosis and management. Transsphenoidal selective adenomectomy is the optimal treatment because of its higher remission rates. However, technical and anatomic aspects should be considered in pediatric patients.

The humanitarian aid of neurosurgical missions in Peru: A chronicle and future perspectives.

Background: The unmet neurosurgical need has remained patent in developing countries, including Peru. However, continuous efforts to overcome the lack of affordable care have been achieved, being neurosurgical missions one of the main strategies. We chronicle the humanitarian labor of organizations from high-income countries during their visit to Peru, the contributions to local trainees' education, and the treatment of underserved patients. Furthermore, we discuss the embedded challenges from these missions and the future perspective on long-term partnerships and sustainability. Methods: This is a narrative review. We searched the literature in PubMed and Google Scholar about neurosurgical missions conducted in Peru. Results: Since 1962, twelve organizations from high-income countries have delivered humanitarian help in Peru by training local neurosurgeons, treating low-income patients, and providing surgical instrumentation. Out of the three main regions of Peru, cities on the coast and highlands have hosted most of these missions, with no reported outreach in the amazon area. About 75% of the organizations are headquartered in the United States, followed by Canada, Luxembourg, and Spain. In addition, 50% of the organizations have an active partnership. The predominant focus of these missions has been pediatrics, neuro-oncology, and spine surgery. Conclusion: Neurosurgical missions have represented a strategy to close the disparity in education and treatment in Peru. However, additional efforts must be conducted to improve long-term partnership and sustainability, such as adopting standardized indicators for progress tracking, incorporating remote technologies for continuous training and communication, and expanding partnerships in less attended areas.
