Peripheral nerve tumours: A 66-case retrospective study.

Background/objectives: Peripheral nerve tumours (PNT) are rare lesions that are generally categorised as soft tissue tumours, so they are usually managed by a range of surgical disciplines such as plastic, orthopaedic and trauma surgery, dermatology, general surgery and neurosurgery. Appropriate knowledge of the therapeutic indication and surgical management are essential in order to avoid neurological deficit.

Materials And Methods: This is a retrospective study of 66 tumour lesions in 64 patients, acquired from the joint experience of 2surgical teams specialised in peripheral nerve surgery.

Neuroendoscopic biopsy: analysis of a series of 80 patients.

Neuroendoscopy enables diagnostic biopsy of intraventricular and/or paraventricular tumors and the simultaneous treatment of associated hydrocephalus in selected cases. The objective of this paper was to analyze the effectiveness and safety of this procedure. This retrospective study included 80 patients between 2 months and 78 years old diagnosed with intraventricular and/or paraventricular expansive lesion who underwent neuroendoscopic biopsy from 2004 to 2016.

Obstetric brachial plexus palsy: reviewing the literature comparing the results of primary versus secondary surgery.

Obstetric brachial plexus injuries (OBPP) are a relatively common stretch injury of the brachial plexus that occurs during delivery. Roughly 30 % of patients will not recover completely and will need a surgical repair. Two main treatment strategies have been used: primary surgery, consisting in exploring and reconstructing the affected portions of the brachial plexus within the first few months of the patient's life, and secondary procedures that include tendon or muscle transfers, osteotomies, and other orthopedic techniques.

The phrenic nerve as a donor for brachial plexus injuries: is it safe and effective? Case series and literature analysis.

Background: Controversy exists surrounding the use of the phrenic nerve for transfer in severe brachial plexus injuries. The objectives of this study are: (1) to present the experience of the authors using the phrenic nerve in a single institution; and (2) to thoroughly review the existing literature to date.

Methods: Adult patients with C5-D1 and C5-C8 lesions and a phrenic nerve transfer were retrospectively included.

Endoscopic endonasal resection of clival xanthoma: case report and literature review.

Bone xanthoma is an extremely rare and benign tumor in terms of its nature and growth over time. We describe the first case coexisting with ventriculomegaly secondary to aqueduct stenosis (non-tumoral hydrocephalus), the second xanthoma of the clivus described to date. The patient was a 51-year-old woman with headaches and absence seizures.

[Thoracic Outlet Syndrome: is it always a surgical condition? Analysis of a series of 31 cases operated by the supraclavicular route].

Background: Thoracic Outlet Syndrome is a compression of the brachial plexus that remains highly controversial. Classification in True or Neurogenic Outlet (TTO) and Disputed or Non-neurogenic Outlet (DTO) is becoming very popular. The former is characterized by a muscular atrophy of the intrinsic muscles of the hand, while the latter has only sensitive symptoms.

[Brachial plexus compression from supraclavicular encapsulated fat necrosis. A case report].

We report the case of a 44-year-old male, lacking clinical history of previous illness, who had surgery at our hospital to treat a mass in the supraclavicular space. The patient presented with a 1-month progressive distal paresis of the left arm. The histo-pathological examination of the mass revealed an encapsulated fat necrosis.

A literature review of intercostal-to-musculocutaneous-nerve transfers in brachial plexus injury patients: Does body mass index influence results in Eastern versus Western countries?

Background: A wide range of results have appeared in the literature for intercostal nerve transfers in brachial plexus patients. Oriental countries generally have a lower body mass index (BMI) than their occidental counterparts. We analyzed published series of intercostal nerve transfers for elbow reinnervation to determine if a difference in outcomes exists between Eastern and Western series that could be inversely related to BMI.

Clinical usefulness of coregistered 11C-methionine positron emission tomography/3-T magnetic resonance imaging at the follow-up of acromegaly.

Objective: This study sought to characterize the utility of coregistered 11C-methionine positron emission tomography (MET-PET) with 3-T magnetic resonance imaging (3T MRI) in the diagnosis and follow-up of pituitary adenomas in patients with acromegaly and to compare MET-PET and 18F-fluorodeoxyglucose emission tomography (FDG-PET) for the evaluation of active or recurrent disease.

Methods: This is a prospective observational study. It included a total of 17 patients, 6 patients with a new diagnosis of acromegaly and 11 patients who had previously undergone resection of a confirmed growth hormone-secreting adenoma.

[Cranial fasciitis: a case report and review of the literature].

Cranial fasciitis is an uncommon, rapidly-growing, benign, non-tumoural, myofibroblastic lesion of the skull, found mainly among young children in their first year of life. It is histologically similar to nodular fasciitis and pseudosarcomatous fasciitis. It may mimic more aggressive pathologies, such as sarcomatosis or histiocytosis, due to its rapid, nodular growth in subcutaneous tissue.

[Isolated traumatic injuries of the axillary nerve. Radial nerve transfer in four cases and literatura review].

Objective: To analyze the results of an initial series of four cases of traumatic injuries of the axillary nerve, treated by a nerve transfer from the triceps long branch of the radial nerve. An extensive analysis of the literature has also been made.

Materials And Methods: Four patients aged between 21 and 42 years old presenting an isolated traumatic palsy of the axillary nerve were operated between January 2007 and June 2010.

[Sciatica secondary to extrapelvic endometriosis affecting the piriformis muscle. Case report].

Objective: We present a case report of symptomatic compression of the right sciatic nerve notch, secondary to piriformis muscle endometriosis, as well as a literature review.

Material And Methods: We report the case of a 29-year-old woman with 2-year evolution of right chronic sciatica. During the first year, symptoms were episodic and associated with menstruation.

Endoscopic Third Ventriculostomy Success Score (ETVSS) predicting success in a series of 50 pediatric patients. Are the outcomes of our patients predictable?

Purpose: In our series of endoscopic third ventriculostomy (ETV), we sought to establish the relationship between the preoperative prediction using the Endoscopic Third Ventriculostomy Success Score (ETVSS) and the postsurgical success rate.

Materials And Methods: This descriptive analytical study comprised 50 pediatric patients who underwent 58 ETV procedures between 2003 and 2011. Data regarding clinical, surgical, and radiological findings were obtained from a continuously updated database.

Bell's palsy and partial hypoglossal to facial nerve transfer: Case presentation and literature review.

Background: Idiopathic facial nerve palsy (Bell's palsy) is a very common condition that affects active population. Despite its generally benign course, a minority of patients can remain with permanent and severe sequelae, including facial palsy or dyskinesia. Hypoglossal to facial nerve anastomosis is rarely used to reinnervate the mimic muscle in these patients.

[Primary prophylaxis of early seizures after surgery of cerebral supratentorial tumors: Group for the Study of Functional-Sterotactic Neurosurgery of The Spain Society of Neurosurgery recommendations].

Our review of the literature is basically focused on the primary prophylaxis of early seizures after surgery of cerebral supratentorial tumors, with the aim of suggesting several recommendations in medical antiepileptic treatment to avoid this kind of seizures which occur immediately after surgery. In conclusion, it is recommended to provide criteria for prophylaxis of early seizures after surgery of cerebral supratentorial tumors. It́s recommended a one week treatment with antiepileptic drugs in patients who didńt have seizures jet, starting immediately after the surgical treatment.
