Aim To determine whether our E-diary can be used to diagnose migraine and provide more reliable migraine-related frequency numbers compared to patients’ self-reported estimates. Methods We introduced a self-developed E-diary including automated algorithms differentiating headache and migraine days, indicating whether a patient has migraine. Reliability of the E-diary diagnosis in combination with two previously validated E-questionnaires was compared to a physician’s diagnosis as gold standard in headache patients referred to the Leiden Headache Clinic (n = 596). In a subset of patients with migraine (n = 484), self-estimated migraine-related frequencies were compared to diary-based results. Results The first migraine screening approach including an E-headache questionnaire, and the E-diary revealed a sensitivity of 98% and specificity of 17%. In the second approach, an E-migraine questionnaire was added, resulting in a sensitivity of 79% and specificity of 69%. Mean self-estimated monthly migraine days, non-migrainous headache days and days with acute medication use were different from E-diary-based results (absolute mean difference ± standard deviation respectively 4.7 ± 5.0, 6.2 ± 6.6 and 4.3 ± 4.8). Conclusion The E-diary including algorithms differentiating headache and migraine days showed usefulness in diagnosing migraine. The use emphasised the need for E-diaries to obtain reliable information, as patients do not reliably recall numbers of migraine days and acute medication intake. Adding E-diaries will be helpful in future headache telemedicine.

Background: Study of correlation between the cytology and histopathological ndings of nonneoplastic and neoplastic breast lesion. Method : The present prospective observational study was conducated in jlnmc for a period of 6 months from 15th April to 14th Sept. we had studied 100 cases and specimens were received in histopathological section of our department.Gross examination of speciemens did followed by xation ,proper sampling and tissue processing. Result: Total 100 cases were studied of which 38 cases were nonneoplastic, 36 cases were benign neoplastic lesion,5 cases borderline and 21 cases were malignant.Over all broadenoma was most common benign lesion with 18 cases. Invasive ductal carcinoma nos were most common malignant lesion followed by lobular carcinoma.malignant phylloid was the most common nonepithelial malignancy. Conclusion: Histology remains gold standard for diagnosis of breast lesion
