Malformación de Chiari tipo i descubierta a través de una neuralgia glosofaríngea / Chiari type i malformation discovered through a glossopharyngeal neuralgia

La neuralgia glosofaríngea es una enfermedad rara cuyo tratamiento inicial es farmacológico. Cuando la terapia médica no es eficaz, se encuentran disponibles diferentes opciones quirúrgicas, incluida la radiocirugía estereotáctica, la descompresión microvascular o la sección de nervios. Se presenta el caso de una mujer de 26 años con neuralgia glosofaríngea y malformación de Chiari. Este tipo raro de neuralgia a veces se asocia con una anomalía de la unión cráneo-cervical. Se realizó una expansión de fosa posterior con duraplastia y descompresión microvascular. La paciente mostró una completa desaparición del dolor, sin necesidad de llevar a cabo la resección de las amígdalas cerebelosas (AU)

Glossopharyngeal neuralgia is a rare disease whose initial treatment is pharmacological. When medical therapy is not effective, different surgical options are available including stereotactic radiosurgery, microvascular decompression or nerve section. It is reported a case of a 26-year-old female with glossopharyngeal neuralgia and Chiari malformation. This rare type of neuralgia sometimes is associated with an abnormality of the cranio-cervical junction. It was performed a posterior fossa expansion with duraplasty and microvascular decompression. The patient showed a complete disappearance of the pain, with no need of tonsil resection (AU)

Patients awaiting surgery for neurosurgical diseases during the first wave of the COVID-19 pandemic in Spain: a multicentre cohort study.

OBJECTIVES: The large number of infected patients requiring mechanical ventilation has led to the postponement of scheduled neurosurgical procedures during the first wave of the COVID-19 pandemic. The aims of this study were to investigate the factors that influence the decision to postpone scheduled neurosurgical procedures and to evaluate the effect of the restriction in scheduled surgery adopted to deal with the first outbreak of the COVID-19 pandemic in Spain on the outcome of patients awaiting surgery. DESIGN: This was an observational retrospective study. SETTINGS: A tertiary-level multicentre study of neurosurgery activity between 1 March and 30 June 2020. PARTICIPANTS: A total of 680 patients awaiting any scheduled neurosurgical procedure were enrolled. 470 patients (69.1%) were awaiting surgery because of spine degenerative disease, 86 patients (12.6%) due to functional disorders, 58 patients (8.5%) due to brain or spine tumours, 25 patients (3.7%) due to cerebrospinal fluid (CSF) disorders and 17 patients (2.5%) due to cerebrovascular disease. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome was mortality due to any reason and any deterioration of the specific neurosurgical condition. Second, we analysed the rate of confirmed SARS-CoV-2 infection. RESULTS: More than one-quarter of patients experienced clinical or radiological deterioration. The rate of worsening was higher among patients with functional (39.5%) or CSF disorders (40%). Two patients died (0.4%) during the waiting period, both because of a concurrent disease. We performed a multivariate logistic regression analysis to determine independent covariates associated with maintaining the surgical indication. We found that community SARS-CoV-2 incidence (OR=1.011, p<0.001), degenerative spine (OR=0.296, p=0.027) and expedited indications (OR=6.095, p<0.001) were independent factors for being operated on during the pandemic. CONCLUSIONS: Patients awaiting neurosurgery experienced significant collateral damage even when they were considered for scheduled procedures.

Impact of the first wave of the SARS-CoV-2 pandemic on the outcome of neurosurgical patients: a nationwide study in Spain.

OBJECTIVE: To assess the effect of the first wave of the SARS-CoV-2 pandemic on the outcome of neurosurgical patients in Spain. SETTINGS: The initial flood of COVID-19 patients overwhelmed an unprepared healthcare system. Different measures were taken to deal with this overburden. The effect of these measures on neurosurgical patients, as well as the effect of COVID-19 itself, has not been thoroughly studied. PARTICIPANTS: This was a multicentre, nationwide, observational retrospective study of patients who underwent any neurosurgical operation from March to July 2020. INTERVENTIONS: An exploratory factorial analysis was performed to select the most relevant variables of the sample. PRIMARY AND SECONDARY OUTCOME MEASURES: Univariate and multivariate analyses were performed to identify independent predictors of mortality and postoperative SARS-CoV-2 infection. RESULTS: Sixteen hospitals registered 1677 operated patients. The overall mortality was 6.4%, and 2.9% (44 patients) suffered a perioperative SARS-CoV-2 infection. Of those infections, 24 were diagnosed postoperatively. Age (OR 1.05), perioperative SARS-CoV-2 infection (OR 4.7), community COVID-19 incidence (cases/105 people/week) (OR 1.006), postoperative neurological worsening (OR 5.9), postoperative need for airway support (OR 5.38), ASA grade ≥3 (OR 2.5) and preoperative GCS 3-8 (OR 2.82) were independently associated with mortality. For SARS-CoV-2 postoperative infection, screening swab test <72 hours preoperatively (OR 0.76), community COVID-19 incidence (cases/105 people/week) (OR 1.011), preoperative cognitive impairment (OR 2.784), postoperative sepsis (OR 3.807) and an absence of postoperative complications (OR 0.188) were independently associated. CONCLUSIONS: Perioperative SARS-CoV-2 infection in neurosurgical patients was associated with an increase in mortality by almost fivefold. Community COVID-19 incidence (cases/105 people/week) was a statistically independent predictor of mortality. TRIAL REGISTRATION NUMBER: CEIM 20/217.

Regresión espontánea de quiste coloide de tercer ventrículo en paciente pediátrica / Spontaneous resolution of colloid cyst of the third ventricle in a pediatric patient

Los quistes coloides son lesiones intracraneales benignas localizadas mayoritariamente en el III ventrículo en la región de los agujeros de Monro. La mayoría se presentan entre la tercera y cuartas décadas de la vida, y son poco frecuentes por debajo de los 10 años. Presentamos el caso de una niña de 2,5 años que presentaba un quiste coloide incidental que fue seguido de manera conservadora, observándose en los estudios de resonancia magnética una progresiva regresión en su tamaño. Realizamos una revisión de los 4 casos similares publicados con anterioridad (AU)

Colloid cyst are benign intracranial lesions located in the III ventricle in the region of the foramen of Monro. The majority present in the third and fourth decades of life and are rare under the age of ten. We report a case of an incidentally colloid cyst presented in a 2.5 -years-old girl who was managed conservatively; follow-up with MRI showed a progressive reduction in size. We review the four similar case previously reported (AU)
