Seeking clinical consensus on risk assessment in anatomical infravesical obstruction of boys - A Delphi study.

Introduction: Infravesical obstruction (IO) is a common urological condition in young boys. Patients may present with various signs and symptoms at different ages, with severity depending to a large extent on the degree of obstruction. Consensus concerning accurate and objective modalities to diagnose IO and to differentiate between an anatomical or functional cause is still lacking.

Functional turbo spin echo magnetic resonance imaging versus tomography for evaluating cervical spine involvement in rheumatoid arthritis.

Study Design: Comparison of findings in plain radiography and conventional tomography with findings in plain radiography and magnetic resonance imaging of the upper cervical spine in consecutive patients with rheumatoid arthritis and with known or suspected abnormalities of the cervical spine.

Objectives: To determine whether plain radiography and magnetic resonance imaging provide enough information to dispense with tomography in investigations of cervical spine involvement in rheumatoid arthritis.

Summary Of Background Data: With the recent advances in magnetic resonance imaging technology and the proliferation of magnetic resonance imaging techniques for specific clinical conditions.

[2 families with meningococcal infection and a hereditary disorder of the 5th component of the complement system].

Within a period of six months, a 20-year-old female with a homozygous deficiency of the C5 component of complement developed meningococcal meningitis twice (different serogroups). Additional C5 deficiencies were not found in relatives. Homozygous deficiency of C5 was also present in another family in which a 16-year-old female and an 18-year-old sister suffered from meningococcal meningitis.

Relationship between contrast medium dose and adverse effects in lumbar myelography.

In a prospective double-blind randomized study involving 40 patients undergoing lumbar myelography, an attempt was made to correlate adverse effects of the examination with contrast medium dosage. Metrizamide for myelography is dispensed in two dosage aliquots, 3.75 and 6.

Whole body distribution of the quaternary ammonium compound thiazinamium (N-methylpromethazine) and promethazine in monkey and mice.

The distribution of 35S-ringlabeled thiazinamium (N-methyl-promethazine) methylsulphate (35S-Th.) and its tertiary analog 35S-promethazine hydrochloride (35S-Pr.) have been studied by means of whole body autoradiography in a squirrel monkey and in mice.
