This 3-dimensional histologic study aimed to provide a precise description of the meningeal structures in the jugular foramen. ⋯ Knowledge of the anatomy of the meningeal architecture of the jugular foramen can be helpful in avoiding surgical complications of the lower cranial nerves when this complex area is approached.

To study the prevalence of OTX1 and OTX2 gene expression in 60 medulloblastoma specimen samples and to establish correlations between gene expression and clinical and histopathological aspects. ⋯ The relative expression of OTX1 and OTX2 was dependent on patient age, tumor location, and histological variant. In addition, OTX2 expression might be a predictive factor for leptomeningeal metastases of medulloblastoma. The OTX pathway should be consider as an important venue for medulloblastomas development.

To investigate the risk factors in the development of pneumonia and its impact on outcome after primary intraventricular hemorrhage (PIVH). ⋯ GCS score and stroke history were independent predictors of pneumonia development after PIVH. Pneumonia after PIVH was associated with longer duration of hospital stay and poorer outcome at 90 days.

Coexistence of an intracranial germ cell tumor with a growing arteriovenous fistula: a case report.
A 26-year-old man was admitted with complaints of progressive depressive mood and general fatigue. Magnetic resonance imaging revealed diffuse enhanced lesions in the neurohypophyseal, pineal, and paraventricular regions and ventricular wall. ⋯ To the best of our knowledge, this is the first reported case of an intracranial germ cell tumor coexistent with a growing AVF. AVF developed within a CRT-refractory teratomatous component, which was successfully treated with embolization followed by surgical resection.

Cervical tuberculosis accounts for only 4.2%-12% of the total incidence of spinal tuberculosis cases. Although antituberculosis drugs have been the mainstay treatment of cervical tuberculosis, they have been ineffective against the symptoms of existing spinal deformities and spinal cord compression, which often require surgical intervention. The conventional surgical methods have been anterior debridement and titanium mesh, cage bone graft fusion and internal fixation. However, all have certain deficiencies regarding the stability of fixation. ⋯ To the best of our knowledge, we have reported the first clinical application of 3-dimensional printing-assisted cervical anterior bilateral pedicle screw fixation of an artificial vertebral body. We accomplished ultrashort segment fixation, with excellent clinical outcomes obtained, which were maintained at the recent 2-year follow-up examination.
