Information was obtained based on a review of medical records for the years 2002–2006 in sequential order.Results: The ADHD predominantly inattentive subtype affected 29.7% of patients, ADHD predominantly hyperactive-impulsive was found in 5.2%, and the combined subtype in 65.1%. Overall, a significant lower Clinical Global Impression (CGI) score and mean number of DSM-IV TR (Diagnostic and Statistical Manual of Mental Disorders Fourth Edition, Text Revision) symptoms by subtype were found after one year of treatment with immediate-release methylphenidate; CGI decreased from 4.51 to 1.69, symptoms of inattention from 7.90 to 4.34, symptoms of hyperactivity from 6.73 to 3.39, and combined subtype symptoms from 14.62 to 7.7. Satisfaction with immediate-release methylphenidate after one year was evaluated as “very satisfied” or “satisfied” by 86.90% of the sample; 25.75% of all patients reported at least one adverse effect. At the end of the study, 41.47% of all the patients treated with immediate-release methylphenidate were still receiving it, with a mean time of 3.80 years on therapy.Conclusion: Good efficacy and safety results were found for immediate-release methylphenidate in patients with ADHD.Keywords: attention deficit hyperactivity disorder, ADHD, pharmacologic treatment, methylphenidate, satisfaction

Purpose: To assess the diagnostic value of ultrasound (US)‐guided 14 G core needle breast biopsy in non‐palpable suspicious breast lesions. Material and Methods: From August 1997 to April 2001, 198 patients with 204 suspicious non‐palpable breast lesions underwent US‐guided large core needle biopsy. Biopsies were performed with a free‐hand technique using US equipment with a 7.5 MHz linear‐array transducer; a minimum of three cores were obtained from each lesion. Pathological findings in US‐guided core biopsy were correlated to findings in subsequent surgery or long‐term (more than 2 years) imaging follow‐up. Results: Among the 204 non‐palpable breast lesions for which histopathological findings were obtained by US‐guided core biopsy, 118 were malignant (114 carcinoma, 2 metastasis, 1 lymphoma, and 1 malignant phyllodes tumor) and 86 were benign (4 carcinoma and 82 benign lesions confirmed at surgery or after at least 2 years of follow‐up). Sensitivity, specificity, positive predictive value, and negative predictive value for diagnosis of malignancy in our series were 97%, 100%, 100%, and 95%, respectively. Diagnostic yield with 1, 2, 3, and 4 specimens per lesion was 73.5%, 88%, 94%, and 97.5%, respectively. Conclusion: US‐guided core needle biopsy is a sensitive percutaneous biopsy method for diagnosing non‐palpable breast lesions. To achieve a high diagnostic yield, a minimum number of three cores per lesion is advisable. [ABSTRACT FROM AUTHOR]
