[Cell saver use during knee arthroplasty].

Backgound: Gonarthrosis is a degenerative condition that importantly limits an individua's performance. Surgical treatment is used in patients with important functional limitation and severe pain. Knee arthroplasty is one of the surgeries with the best functional results in patients with this condition.

[Profile of the patient with failed back surgery syndrome in the National Institute of Rehabilitation. Comparative analysis].

Background: Failed back surgery syndrome is a complication of spine surgery that leads to chronic pain and disability, often with disastrous emotional consequences to the patient.

Aim: To compare the profile of patients whose first surgery was performed in our hospital versus a group that underwent first spine surgery in a different centre.

Methods: Retrospective study with 65 patients; 18 formed group I (first spine surgery performed in our institution), and 47 patients in group II (first surgery performed in another hospital).

Influence of depression symptoms on patient expectations and clinical outcomes in the surgical management of spinal stenosis.

Object: This prospective cohort study was designed to determine the influence of depressive symptoms on patient expectations and the clinical outcomes of the surgical management of lumbar spinal stenosis.

Methods: Patients with an age > 45 years, a diagnosis of lumbar spinal stenosis at one level, and an indication for decompressive surgery were included in this study. Data for all of the following parameters were recorded: age, sex, highest level of education, and employment status.

Traumatic posterior L4-L5 fracture dislocation of the lumbar spine: a case report.

Study Design Case report. Objective The diagnosis and surgical management of a patient with traumatic bilateral posterior dislocation of L4-L5 is presented with a thorough review of the existing literature. Summary of Background Data Traumatic dislocation of L4-L5 has been reported in the English literature in only five cases; of these, only two were retrolisthesis.

[Forestier disease. Case report and literature review].

Background: Forestier disease is a systemic disorder characterized by ossification of the anterior spinal longitudinal ligament (ALL) in at least three adjacent vertebrae, and diffuse spinal enthesopathy. Indication for surgical treatment is rare and limited to cases of related myelopathy, fracture or significant dysphagia. Few cases of surgical treatment are reported in the medical literature.

The impact of body mass index and central obesity on the spino-pelvic parameters: a correlation study.

Introduction: Obesity is an increasing problem of epidemic proportion, and it is associated with various musculoskeletal disorders, including impairment of the spine. However, the relationship between obesity and spino-pelvic parameters remains to date unsupported by an objective measurement of the mechanical behavior of the spino-pelvic parameters depending on body mass index (BMI) and the presence of central obesity. Such analysis may provide a deeper understanding of this relationship.

Knowledge of skull base anatomy and surgical implications of human sacrifice among pre-Columbian Mesoamerican cultures.

Human sacrifice became a common cultural trait during the advanced phases of Mesoamerican civilizations. This phenomenon, influenced by complex religious beliefs, included several practices such as decapitation, cranial deformation, and the use of human cranial bones for skull mask manufacturing. Archaeological evidence suggests that all of these practices required specialized knowledge of skull base and upper cervical anatomy.

Differences in pelvic parameters among Mexican, Caucasian, and Asian populations.

Object: The aim of this study was to describe the pelvic parameters in a sample of healthy Mexican volunteers and to compare them with previously reported data for Caucasian and Asian populations.

Methods: This was a transversal study that included a sample population of healthy Mexican volunteers. Age, sex, and lateral radiographs of the lumbosacral region with the individual standing to obtain the pelvic parameters of pelvic tilt (PT), sacral slope (SS), pelvic incidence (PI), and lumbar lordosis (LL) were recorded in each volunteer.

A look at Mayan artificial cranial deformation practices: morphological and cultural aspects.

Induced deformation of the cranial vault is one form of permanent alteration of the body that has been performed by human beings from the beginning of history as a way of differentiating from others. These procedures have been observed in different cultures, but were particularly widespread in Mesoamerica. The authors examined and reviewed the historical and anthropological literature of intentional deformation practices in Mayan culture.

Thyroid follicular carcinoma presenting as skull and dural metastasis mimicking a meningioma: a case report.

Follicular thyroid cancer rarely manifests itself as a distant metastatic lesion. We report a case of a 61-year-old woman presented with a solid mass located in the left temporo-occipital region. The 3D computed tomography showed a large solid mass with high vascularity, skull erosion and supra-infratentorial epidural mass effect.

Grading scale for prediction of outcome in primary intracerebral hemorrhages.

Background And Purpose: This study aimed to independently derive an intracerebral hemorrhage grading scale (ICH-GS) for prediction of 3 outcome measures.

Methods: We evaluated 378 patients with primary ICH at hospital arrival and during the next 30 days. Independent predictors were identified by multivariate models of in-hospital and 30-day mortality.

Multiple simultaneous intracerebral hemorrhages following accidental massive lumbar cerebrospinal fluid drainage: case report and literature review.

Multiple simultaneous intracerebral hemorrhages (ICH) are uncommon. We report the case of an 80-year-old woman with previous diagnosis of normal pressure hydrocephalus and who was brought to our hospital with altered mental status and urinary incontinence. Medical history of hypertension, hematological disorders or severe head trauma was absent.

Hypertensive intracerebral hemorrhage in young people: previously unnoticed age-related clinical differences.

Background And Purpose: Hypertensive intracerebral hemorrhage (ICH) in young people has been the object of only succinct analyses. Therefore, it is unclear whether extrapolation of the information obtained from older patients is also valid for the young. Here we describe young persons with hypertensive ICH and compare them with their older counterparts to determine whether age-related clinical differences exist.

Idiopathic hypertrophic cranial pachymeningitis successfully treated with weekly subcutaneous methotrexate.

Idiopathic hypertrophic cranial pachymeningitis is a very infrequent disorder. Adequate management is still a matter of debate. We describe the use of low-dose pulse methotrexate in treating a 63-year-old woman with idiopathic hypertrophic cranial pachymeningitis.

[Linear scleroderma en coup de sabre: neurological symptoms, images and review].

Introduction: 'Sword stroke' linear scleroderma, which is better known as linear scleroderma en coup de sabre (LSCS), is a rare disease with an uncertain causation that is characterised by progressive craniofacial focal atrophy and is, at least in part, different from Parry-Romberg syndrome (PRS).

Case Reports: Here, we report on the cases of 3 patients with LSCS (2 females and 1 male, with a mean age of 40 years). The main neurological symptoms were headache and seizures.

[Intracerebral haemorrhage in a referral hospital in the central-western region of Mexico].

Introduction: Intracerebral haemorrhage (ICH) has received little attention in studies in Mexico. Isolated reports talk of high frequency, its importance as a disorder among young people, its being mainly located in the lobar regions and a high rate of recurrence.

Aims: The objective of this study was to characterise the clinical, radiological, therapeutic and prognostic spectrum of ICH in a general hospital in the central-western region of Mexico.
