Background: 18F-Fluorodeoxyglucose positron emission tomography-computed tomography (PET-CT) has become a common imaging modality for detecting metastatic melanoma. However, the identification of lesions intraoperatively can be difficult.
Objective/methods: We describe an innovative multimodality approach to tumor localization using preoperative PET-CT and intraoperative ultrasonography and describe cases in which this technique was used.
Background: Histopathologic analysis remains the gold standard for the pathologic diagnosis of melanoma. Numerous histologic criteria are used to diagnose melanoma, but none alone are sufficient to establish this diagnosis. Therefore, differentiating between benign pigmented lesions and melanoma may be controversial.

The study assessed the effectiveness of operational, community-based larval habitat surveillance systems within the Urban Malaria Control Programme (UMCP) in urban Dar es Salaam, Tanzania.
Methods: Cross-sectional surveys were carried out to assess the ability of community-owned resource persons (CORPs) to detect mosquito breeding sites and larvae in areas with and without larviciding.
