In witness whereof, the said plenipotentiaries have signed the present pact in Arabic, Turkish and English, all three texts being equally authentic except in the case of doubt when the English text shall prevail.
In the case of doubt, preclinical data comparing the pharmacological activity (e.g., affinity to a receptor) of the precursor and the radiolabelled compound should be provided to support this approach.
We think that it is more helpful to explicitly ask the patient about neurological symptoms and in the case of doubt lean towards lumbar puncture to rule out CNS involvement.
All double publications were excluded, and in the case of doubt full text publications were obtained.
If the examined reported pain or discomfort, radiating pain or numbness during the past 7 days, or if pain or pronounced reduced mobility was elicited in the basic examination, or in the case of doubt, the examiner continued with the detailed physical examination (described below) of the actual anatomical region.
The question about perceived pain during the past 12 months was included in the screening procedure because information about this can be valuable in the case of doubt if the actual examined should be qualified for the more detailed physical examination or not (Sluiter, Rest, and Fring-Dresen 2001).
In the case of any doubt from ultrasonography, a magnetic resonance imaging should be performed and nephrectomy should be considered.
A psychiatric opinion should also be sought as a second line of treatment in the event of resistance to treatment even after an increase in dose, or in the case of any doubt concerning the diagnosis.
In the case of British Telecom, no one doubted the practical need.
