The authors present the anatomical considerations that support a surgical alternative designed for the surgical treatment of Carpal Tunnel Syndrome (CTS). The design of the technique maintains the concept of minimally invasive and at the same time the one of not requiring the use of endoscope. The results obtained in the last 100 cases are presented.

The care of neurosurgical patients in intensive care units has proven to be beneficial not only for patients but also for hospital institutions. However, the benefits of the care that these units provide to the neurocritical patient depend on multiple factors intrinsic to the patient, which should be studied in order to make better use of resources in the care of them. The present descriptive work shows an analysis of the characteristics of the patients admitted by the specialty of Neurosurgery to the Intensive Care Unit of the Ricardo Palma Clinic during 2007.

The meningioma has the second place in frequency between the intracranial tumors. The best treatment is complete surgical resection with resection of its dural insertion and areas of cranial invasion.At present, Stereotactic Radiosurgery has become a reasonable therapeutic alternative, especially for meningiomas of the skull base due to its high rate of tumor control and low complications.

Infectious diseases and infestations are due to the local aggression of the central nervous system and its envelopes, by microbial or parasitic agents, capable of causing damage to our health, causing local and general symptoms.This pathology can afect: CRANE AND BRAIN: Epidural empyema, Subdural empyema, intracerebral abscess, ventriculitis. VERTEBRAL AND SPINAL CORD : Epidural empiema, subdural empyema or intramedullary abscess. CNS  CYSTICERCOSIS: Racemous cysticercosis, cystic cysticercosis.
