Use of Artificial Intelligence Chatbots in Interpretation of Pathology Reports.

Importance: Anatomic pathology reports are an essential part of health care, containing vital diagnostic and prognostic information. Currently, most patients have access to their test results online. However, the reports are complex and are generally incomprehensible to laypeople.

A phase I study of 99mTc-hR3 (DiaCIM), a humanized immunoconjugate directed towards the epidermal growth factor receptor.

A phase I trial was conducted to evaluate the safety, tumour and normal tissue localization, pharmacokinetics and radiation dosimetry of Tc-hR3, a humanized monoclonal antibody directed towards the epidermal growth factor receptor, in 12 patients with recurrent or metastatic epithelial malignancies. Patients were injected intravenously with 3.0 mg or 6.

Sentinel lymph-node biopsy after previous wide local excision for melanoma.

Objective: To document experience with sentinel lymph-node biopsy in patients who have already undergone a wide local excision for melanoma because in many centres previous wide excision has been a contraindication for sentinel lymph-node biopsy.

Design: A prospective cohort study.

Setting: A tertiary care academic cancer centre.

When to use bone scintigraphy. It can reveal things other studies cannot.

Despite advances in nuclear medicine, bone scintigraphy remains an important imaging technique. It is sensitive in detecting stress fractures and bone metastases and can assess suspected injury that is difficult to see on plain films (e.g.

Outcome of hepatobiliary scanning in neonatal hepatitis syndrome.

Unlabelled: To evaluate the diagnostic information gained from hepatobiliary scanning in infants, we reviewed 86 consecutive infants who were < or = 4 mo old and were treated for conjugated hyperbilirubinemia at the Hospital for Sick Children in Toronto between 1985 and 1993 and who had technetium iminodiacetic hepatobiliary scanning and a percutaneous liver biopsy performed in close temporal proximity.

Methods: Retrospective reviews of hospital charts and blinded reviews of hepatobiliary scans were performed.

Results: There were 58 male and 28 female infants (age range, 2-124 days; mean = 65 days).
