Background: Osteoblastoma is a benign bone-forming tumor, sometimes locally invasive, that may involve any bone. The highest incidence is between 20 and 30 years of age, and there are no cases described in the elderly. Methods: We report a case of an elderly patient with a lesion in the lumbar spine in which osteoblastoma diagnosis was made....

A migrant from Palestine came to our attention for weakness of dorsiflexion of the left foot and hypoesthesia of the homolateral common peroneal nerve territory. Skin biopsies from skin lesions in the hypoesthetic area were not diagnostic. Radiological investigation showed focal nerve enlargement with a possible focal lesion. At this time, and...

Severe traumatic brain injury (TBI) is frequently associated with an elevation of intracranial pressure (ICP), followed by cerebral perfusion pressure (CPP) reduction. Invasive monitoring of ICP is recommended to guide a step-by-step "staircase approach" which aims to normalize ICP values and reduce the risks of secondary damage. However, if...

Introduction: Leprosy is nowaday increasingly encountered in non-endemic countries. Nerve involvement is common. Swelling of the nerves may lead to entrapment neuropathy causing pain and neurological deficits. Delay in diagnosis and treatment may lead to loss of chance of improvement. Surgical decompression in conjunction with medical therapy...

Intraorbital schwannomas account for 1 to 4% of all orbital tumors, they can remain subclinical for years before usually manifesting with diplopia and progressive proptosis. We present a rare case of schwannoma of the right infraorbital nerve. The patient underwent biopsy and gross total resection of the tumor in two different surgical times....

Background: We describe a modified endoscopic diving technique with an alternative irrigation system different than the one used by Locatelli et al. (CLEARVISION II, Karl Storz and Co., Tuttlingen, Germany). Methods: From January 2016 to October 2018, our senior surgeon performed the modified endoscopic diving technique in 76 endoscopic...

Introduction: Transpterygoid approach is an expanded endonasal approach (EEA) that allows surgical access to the medial infratemporal fossa, to the skull base area of petrous bone and to the Meckel's cave. During this approach, a sacrifice of sphenopalatine artery is often required, leading to the need of contralateral Hadad-Bassagasteguy flap...

BACKGROUND: Nontraumatic atlantoaxial subluxation, also known as Grisel syndrome, is a rare disease that usually affects children. The typical presentation is torticollis in patients with a history of surgical operations or airway infections.METHODS: We describe 5 patients with Grisel syndrome, referring to medical care for a torticollis, a few...

Traumatic brain injury frequently causes an elevation of intracranial pressure (ICP) that could lead to reduction of cerebral perfusion pressure and cause brain ischemia. Invasive ICP monitoring is recommended by international guidelines, in order to reduce the incidence of secondary brain injury; although rare, the complications related to ICP...

Posterior cranial fossa tumours frequently develop hydrocephalus as first presentation in up to 80% of paediatric patients and 21.4% of adults, although it resolves after tumour removal in 70–90% and 96%, respectively. New onset hydrocephalus is reported in about 2.1% of adult and 10–40% of paediatric patients after posterior fossa surgery....

Purpose: Endoscopic endonasal skull base surgery (EESBS) is a clean-contaminated procedure. Guidelines regarding the antibiotic prophylaxis in EESBS have not been developed yet, and today, there are no universally accepted protocols. In this article, we investigated the efficacy of our new ultra-short antibiotic prophylaxis protocol for EESBS...

Objective †The Kawase approach provides access to the petroclival and posterior cavernous sinus regions, cerebellopontine angle, and upper basilar artery territory. Nevertheless, it remains one of the most challenging approach for neurosurgeons, due to the considerable related morbidity and mortality. The goal of this study was to evaluate...

Background: Nowadays, the endoscopic endonasal approach to sellar and parasellar region tumors is a common technique in neurosurgery, and surgical nuances, complications, and management strategies are shared in a multidisciplinary setting between neurosurgeons and ear, nose, and throat surgeons. Due to the heterogeneity of its variations, the...

Purpose: Spinal aneurysms are rare vascular malformations, commonly associated with spinal AVMs. AVM-associated spinal aneurysms are burdened by significant morbidity. The purpose of our study is to evaluate the best treatment strategy for these uncommon vascular lesions and to report an illustrative case. Methods: We reviewed clinical and...

In December 2019, an outbreak of illness caused by a novel coronavirus (2019-nCoV, subsequently renamed SARS-CoV-2) was reported in Wuhan, China. Coronavirus disease 2019 (COVID-19) quickly spread worldwide to become a pandemic. Typical manifestations of COVID-19 include fever, dry cough, fatigue, and respiratory distress. In addition, both the...

BACKGROUND: Dermoid and epidermoid cysts are among the most frequent lesions of the scalp in the pediatric population. Optimal management of a suspected dermoid or epidermoid cyst in children is debated: Some authors advocate conservative management on the basis of the benign histology of these entities, while others prefer surgical...

Background: Cardiac arrest (CA) is a sudden event that is often characterized by hypoxic-ischemic brain injury (HIBI), leading to significant mortality and long-term disability. Brain tissue oxygenation (PbtO2) is an invasive tool for monitoring brain oxygen tension, but it is not routinely used in patients with CA because of the invasiveness...

Background: In COVID-19 patients with acute respiratory distress syndrome (ARDS), the effectiveness of ventilatory rescue strategies remains uncertain, with controversial efficacy on systemic oxygenation and no data available regarding cerebral oxygenation and hemodynamics. Methods: This is a prospective observational study conducted at San...
