Granuloma annulare - is it a paraneoplastic condition for malignant lymphoma?

J Dtsch Dermatol Ges 2021 May 5. Epub 2021 May 5.

Department of Dermatology, Allergology and Venereology, Saarland University Hospital, Homburg/Saar.

In recent years, an association between granuloma annulare and the occurrence of malignant cutaneous lymphomas in the sense of a facultative paraneoplasia has been observed several times. The aim of the present work is to provide an overview of the currently available literature on granuloma annulare as well as an analysis of its association with cutaneous lymphomas. Using the example of two patients with granuloma annulare and associated cutaneous lymphomas, we would like to sensitize clinically active dermatologists and dermatopathologists to the possible association between these two diseases.

Triggering the proboscis extension reflex (PER) in Rhodnius prolixus.

J Insect Physiol 2021 Apr 30:104249. Epub 2021 Apr 30.

Institut de Recherche sur la Biologie de l'Insecte, UMR 7261 CNRS - University of Tours, Tours, France. Electronic address:

The heat emitted by the host body constitutes a short distance orientation cue for most blood-sucking insects, as is the case of the kissing-bug Rhodnius prolixus. We evaluated here how kissing bugs assess the distance to a warm target, in order to reach it by displaying the Proboscis Extension Reflex (PER). We confronted blind-folded insects to a thermal source either at 35° or at 40°C under both, open- and closed-loop conditions. Read More

Wound Management Strategy for Treatment of Localized Cutaneous Leishmaniasis Using the TIME Framework.

Wounds 2021 Jan;33(1):E6-E9

Department of Dermatology, University of Pisa, Pisa, Italy.

Introduction: The current drugs available for the treatment of cutaneous leishmaniasis (CL) often cause several adverse events, and the risk-benefit ratio is low due to the risk of severe complications. Current treatment recommendations are based on data from areas endemic for leishmaniasis and are not always perfectly applicable, especially in cases of imported CL. Thus, it is crucial to assess the level of severity in each case to provide the most appropriate treatment modality. Read More

Approach to the Patient with a Skin and Soft Tissue Infection.

Infect Dis Clin North Am 2021 Mar;35(1):1-48

Division of Infectious Diseases, Department of Medicine, University of Pennsylvania, Blockley Hall 707, Philadelphia, PA 19104, USA; Department of Epidemiology, Biostatistics and Informatics, University of Pennsylvania, Philadelphia, PA, USA. Electronic address:

The diagnosis of a skin and soft tissue infection (SSTI) requires careful attention to a patient's history, physical examination, and diagnostic test results. We review for many bacterial, viral, fungal, and parasitic pathogens that cause SSTIs the clues for reaching a diagnosis, including reported past medical history, hobbies and behaviors, travel, insect bites, exposure to other people and to animals, environmental exposures to water, soil, or sand, as well as the anatomic site of skin lesions, their morphology on examination, and their evolution over time. Laboratory and radiographic tests are discussed that may be used to confirm a specific diagnosis. Read More
