Association Between MRI Findings of Facet Arthropathy and Synovitis With Health-Related Outcome and Pain Scores Following Therapeutic Lumbar Facet Injections.

Low back pain is a common complaint among adults. The facet joint is a major source of lumbar pain, and therapeutic facet injections have gained popularity as a minimally invasive treatment option. In addition, magnetic resonance imaging (MRI) utilization for diagnosing low back pain has increased significantly over the past few decades.

Monitoring bromide loss in bromoacetyl-derivatized polyribosylribitol polysaccharide in Haemophilus influenzae type b for PedvaxHIB® by capillary electrophoresis and NMR spectroscopy.

PedvaxHIB® is an effective pediatric vaccine for protecting infants from invasive gram-negative bacterium Haemophilus influenzae type b. It is a highly purified capsular polysaccharide, polyribosylribitol phosphate that is covalently linked to an outer membrane protein complex of Neisseria meningitidis. PRP is first derivatized with an organic linker, followed by the coupling of a butadiamine group, and then at the end terminal, a bromoacetyl group is attached for conjugation with thiolated OMPC.

[Hip necrosis. A severe complication after intragluteal injection of quinine salt in Bangui, Central African Republic].

Introduction: Intramuscular injection of quinine has been for long the most common treatment for malaria in children in endemic areas of Africa, especially sub-Saharan Africa, and remains too often used. However, it is frequently wrongly performed by unqualified people. When administered in a poorly developed or malnourished child, the injection can be done too deeply in the hip joint instead of the gluteus muscle area.

Effects of Monoamine Oxidase Inhibition on the Reinforcing Properties of Low-Dose Nicotine.

The Food and Drug Administration (FDA) has the authority to regulate cigarette smoke constituents, and a reduction in nicotine content might benefit public health by reducing the prevalence of smoking. Research suggests that cigarette smoke constituents that inhibit monoamine oxidase (MAO) may increase the reinforcing value of low doses of nicotine. The aim of the present experiments was to further characterize the impact of MAO inhibition on the primary reinforcing and reinforcement enhancing effects of nicotine in rats.

[Treatment of complications of intramuscular injection of quinine salts in Africa].

Intramuscular injection of quinine is a mainstay treatment for malaria in children. However it can lead to severe orthopedic complications including sciatic paralysis after intragluteal injection and quadriceps contracture after intraquadricipital injection. This report based on a 98-case series of complications following intramuscular quinine injection that were treated surgically in 88 cases describes clinical findings with special emphasis on the severity.

Giant intraosseous cyst-like lesions in rheumatoid arthritis report of a case.

The term "intraosseous synovial cyst" is used to designate both the epiphyseal cyst-like lesions seen in patients with rheumatoid arthritis (RA) and mucoid cysts, which occur in a different setting. We report the case of a patient in whom a 4-cm cyst-like lesion developed in the left tibia 18 years after onset of RA and 6 years after osmic acid synovectomy of the left knee. Positive contrast arthrography and magnetic resonance imaging visualized a communication between the lesion and the joint space.

Surgery in spinal metastasis without spinal cord compression: indications and strategy related to the risk of recurrence.

[Prospects in video-assisted spinal surgery].

Advances in spinal surgery for both posterior procedures on herniated discs and anterior procedures involving the vertebral body have been greatly affected by developments in video-assisted techniques. Many of the procedures mentioned here are still in the development stage, others have proven their efficacy. Discoscopy, achieved by introducing the endoscope via a posterolateral route into the intervertebral disc, can be used for diagnosis and treatment of the disc and the end plates.

Results of surgical treatment of spinal thoracic and lumbar metastases.

The results of surgical treatment of vertebral metastases were evaluated from a retrospective review of a consecutive series of 100 patients, with special reference to anatomoclinical aspects and functional outcome. The primary tumour in most cases was lung, breast, or prostate; it was unknown in 11 cases. Diagnosis of the metastasis occurred 4-86 months after that of the primary tumour (lung metastasis: 4 months; breast metastasis: 86 months; prostatic metastasis: 22 months).
