Monostotic fibrous dysplasia of the metacarpal: a case report.

Fibrous dysplasia is a bone disease characterized by abnormal differentiation of fibrous tissue in the bones; it is often asymptomatic. It may affect one bone (monostotic) or several bones (polyostotic). The monostotic form primarily affects the ribs, but hardly ever affects the hand.

Vitamin d is related to gait recovery after total hip arthroplasty: A prospective analysis.

Objectives: To investigate the association between baseline serum levels of 25-hydroxyvitamin D (25(OH)D) and gait pattern in patients undergoing total hip arthroplasty (THA).

Methods: Prospective study of patients with hip osteoarthritis undergoing primary THA between January 2012 and December 2013. Blood samples were collected on the day of hospital admission.

[Anesthetic complications in a rehabilitation hospital: is the incidence related to the pre-anesthetic visit?].

Introduction: Approximately 234 million surgeries are done annually worldwide. There is a growing concern for the safety of the anesthetic act, and the pre-anesthetic consultation emerges as an important and widely recommended activity, used as a preventive measure for the emergence of a complication.

Objectives: To describe the complications related to anesthesia, to identify the factors that contribute to its appearance and to reflect on ways to improve clinical practice.

Risk of orthopedic surgical site infections in patients with rheumatoid arthritis treated with antitumor necrosis factor alfa therapy.

Introduction. International guidelines recommend interruption of anti-TNF medications in the perioperative period, but there are no randomized trials to support such recommendation. Objectives.

When the bispectral index (bis) can give false results.

Background And Objectives: The bispectral index (BIS) is a multifactorial parameter derived from the electroencephalogram (EEG), which allows monitoring of the hypnotic component of anesthesia. It was obtained from the algorithm based on the analysis of a large number of EEGs from volunteers and patients undergoing sedation and general anesthesia with different anesthetic agents. The use of BIS to monitor the depth of anesthesia reduces the incidence of intraoperative awakening and recall, among other benefits.

[Management of pain in patient with inoperable sacral tumor: case report.].

Background And Objectives: Different techniques may be used to control cancer pain. This report aimed at describing some therapeutic measures used to treat a patient with a severe and bad responsive pain.

Case Report: A 70-year-old male patient a sacral chordoma of very difficult therapeutic.

[Nitrous oxide action on the central nervous system: electrophysiological study as a sole agent or a coadjuvant].

Background And Objectives: Nitrous oxide is the most widely used inhalational anesthetic worldwide. Its action mechanism is broadly discussed based on results of experimental studies and clinical evidences. The purpose of this study was to evaluate, through specific monitoring, nitrous oxide electrophysiological action on the central nervous system.

[Devic's neuromyelitis optica. Presentation of 2 new cases and review of the bibliography].

Devic's neuromyelitis optica is a clinical entity characterized by severe transverse myelitis, acute unilateral or bilateral optic neuropathy, no clinical involvement beyond the spinal cord or optic nerves and a monophasic or recurrent evolution. We report two cases, both female, affected by spinal cord and visual symptoms suggesting Devic's neuromyelitis. First patient, a 30 y.

[Potentially treatable subacute forms of infection due to the HTLV-1].

Introduction: Tropical spastic paraparesis due to HTLV-I virus is diagnosed at very advanced stages, when there is spinal atrophy present and so only symptomatic treatment can be given. Early diagnosis of HTLV-I infection in unusual syndromes and the use of corticosteroids may help to slow the development of the disease.

Clinical Cases: We describe two Brazilian patients who developed symptoms due to HTLV-I present for less than one year: subacute myelopathy with a sensory level and an ataxic pyramidal syndrome associated with axonal neuropathy, which partly improved after treatment with corticosteroids.

[Spinal cord schwannoma: case report].

The intramedullary localization of schwannomas is rare, corresponding to 0.3% of all intraspinal tumors. The authors report the case of a 52-year-old white female patient that presented with symptoms of spinal compression by the presence of an intramedullary schwannoma at the level C4-C6.
