ABSTRACT
BACKGROUND: Management of chronic mechanical neck pain (CMNP) still represents a challenge. A patient-oriented (Pa-O) therapeutic approach could be considered as the one in which therapies are scheduled at the start of each therapeutic session according to the patient's current physical status, and differs from a prescription-oriented (Pr-O) therapeutic approach, in which therapies are prescribed at the first medical referral and are not adjusted at any time during the treatment period. AIM: To determine if a Pa-O approach may be more beneficial for CMNP patients when compared to a Pr-O one. DESIGN: Randomized controlled trial. POPULATION: 220 CMNP outpatients randomized to either Pa-O group (N.=114) or Pr-O group (N.=106). METHODS: Each group received 10 therapeutic sessions over 3 weeks. Primary outcome measures were pain assessment, evaluated by Visual-Analog-Scale (VAS), and disability level, evaluated by the Neck Pain and Disability Scale (NPDS-I). Secondary outcome measures included patients' response to treatment and treatment failures. Measurements were carried out at baseline (T0) and 1 month after treatment ended (T1). Data were analysed according to the intention-to-treat principle. RESULTS: Patients in both groups displayed at T1 a significant reduction in VAS and NPDS-I scores. The relative changes at T1 were greater in Pa-O group when compared with Pr-O group both for VAS (61.5% versus 48.8%; P<0.005) and for NPDS-I scores (48.4% versus 36.8%; P<0.05). CONCLUSION: A Pa-O approach may be more beneficial in terms of pain and disability improvement in the short-term follow-up in suffers from CMNP. However, the occurrence of a performance-bias due to the increased level of attention from physicians to patients in Pa-O group, cannot be ruled-out. CLINICAL REHABILITATION IMPACT: A Pa-O approach should be considered for CMNP also in an outpatient facility.

The accuracy of transrectal US (TRUS) and of MRI was evaluated in the preoperative staging and in local recurrences of rectal cancers. Fifty-four patients were examined: 45, with known rectal cancer, for preoperative staging, and 9 for the evaluation of local recurrences. Nineteen patients were examined with MRI in basal conditions, 21 after rectal air enema and 5 after paramagnetic contrast enema (Gd-DTPA). The following parameters were evaluated for preoperative staging: wall infiltration, invasion of perirectal fat and adjacent structures, lymph node involvement. Morphologic and signal intensity (on MRI) changes were evaluated for the diagnosis of local recurrences. TRUS provided 2 false positives. In the same patients, basal MRI results were poor, owing to difficult demonstration of the different wall layers, while in the patients studied after air enema, the lesion was hyperintense. In 20 patients with a fat-infiltrating tumor, TRUS provided 3 false negatives and 2 false positives; basal MRI yielded poor results, while air enema and paramagnetic contrast enema clearly demonstrated all fat-infiltrating lesions, with only one false positive.
