Counselor skill influences outcomes of brief motivational interventions

The aim of this study was to estimate the influence of counselor skills during brief motivational interventions (BMIs) on patient alcohol use 12 months later. Ninety-five BMIs delivered by five counselors of similar background and training were recorded and coded using the Motivational Interviewing Skills Code (MISC). Baseline alcohol measures and sociodemographics of patients did not differ across counselors, whereas MISC scores and outcome at 12 months did. Multilevel models showed that counselors with better motivational interviewing (MI) skills achieved better outcomes overall and maintained efficacy across all levels of an important predictor (patient ability to change), whereas counselors with poorer MI skills were effective mostly at high levels of ability to change. Findings indicated that avoidance of MI-inconsistent skills was more important than frequency of using MI-consistent skills and that training and selection of counselors should be based more on the overall MI-consistent gestalt than on particular MI techniques.     

Actitud expectante en el síndrome del cascanueces

Nutcracker syndrome is caused by compression of the left renal vein between the aorta and the superior mesenteric artery where it passes in the fork formed at the bifurcation of these arteries. The phenomenon results in left renal venous hypertension. The syndrome is manifested by left flank and abdominal pain, with or without unilateral haematuria. The nutcracker syndrome has been treated in various ways. We report one case of the syndrome and discuss the place of surveillance in its management.     

Comparison of the effectiveness of the pulsed dye laser 585 nm versus 595 nm in the treatment of new surgical scars

The aim of this study was to compare the effects of the pulsed-dye laser (PDL) at a wavelength of 585 nm with those at 595 nm in the treatment of post-surgical scars, starting on the day of suture removal. The study was a prospective, non-randomized, double-blind, controlled, clinical trial, set in an outpatient clinic. Fifteen outpatients with 21 post-operative scars at least 3 cm long were recruited, and 14 patients with 19 scars completed the study. Scars were divided into three equal portions. Each outer portion was randomly allocated to PDL at 585 nm or at 595 nm (3.5 J/cm², 450 μs, 10 mm spot size), and the center was an untreated control; treatment was composed of three laser sessions at 4-week intervals. A blinded examiner evaluated the three scar sections using the Vancouver scar scale for pigmentation, vascularity, pliability, and height. Cosmetic appearance was evaluated with a visual analog scale. Punch biopsies of three randomly selected scars were evaluated. Pigmentation: more scars after laser treatments were of normal color than in the control, but the difference was not statistically significant. Vascularity: after treatment, more scars had normal vascularity in all three groups than at baseline (P < 0.05); the largest increase was with a wavelength of 585 nm (10.5–94.7%), then 595 nm (15.8–78.9%), then control (5.2–36.6%). Pliability: there was more normal pliability in all three groups than at baseline (P < 0.05), with greater improvements in the laser-treated groups. Height: significantly more flat scars after 585 nm PDL (63.2%) than at baseline (21.1%) (P < 0.05). We observed a slight but non-significant decrease in the scar heights with 595 nm PDL in comparison with the control. Histology: after laser irradiation, the treated sections were more similar to a non-scarring process than the control. Cosmetic outcome: visual analog scales increased in all groups (P < 0.05), but the greatest increases were observed in the 585 nm and 595 nm laser-treated groups (50% and 60%, respectively) compared with controls (30%). There were significantly higher scores with the lasers than for the control (P < 0.001) at each visit after baseline. Both the 585 nm and 595 nm PDL treatments were effective in improving the appearance and normalizing the vascularity and pliability of post-operative scars. Both wavelengths improved the scars’ visual appearance more than controls. We found that 585 nm appears to be the preferred wavelength, as it substantially normalized the height in addition to the vascularity and pliability in a significant number of scars.     

A scoring system as a method to evaluate pilonidal sinus disease to make an easy decision for its management

This study was planned to evaluate prospectively the results of 150 patients with pilonidal sinus treated surgically after planning a score system. The aim was to choose the proper technique for the proper pilonidal sinus disease. From November 2002 to December 2006, 150 patients [130 male, 20 female; average age = 22.65 ± 4.2 (range, 15-46) years] with primary or recurrent pilonidal sinus diseases, operated under spinal anaesthesia or general anaesthesia. All patients were classified into three groups A, B and C. According to the clinical presentations we had three groups of patients: Group A with a score number n = 8 to 10, Group B with a score number n = 11 to 13, and Group C had the number n = 14 to 16. The study helped us in our surgical decision making, particularly in choosing the type of surgery for a given patient by our new scoring system, with promising results and low failure rate.
