Dermatitis chronica athropicans secondary to Borrelia afzelii infection locally acquired in Northern Mexico

Introduction: Acrodermatitis chronica atrophicans (ACA) is a late cutaneous manifestation of Lyme disease characterized by inflammatory lesions that slowly progress to atrophic plaques. The vast majority of ACA cases have been described in Europe and are associated to the genospecies Borrelia afzelii (B. afzelii). We hereby report the first case in Northern Mexico of ACA caused by locally acquired B. afzelii.

We describe a new fish blood fluke (Digenea: Aporocotylidae: Electrovermis zappum n. gen., n. sp.) and its life cycle in the intertidal zone adjacent to Mobile Bay (north-central Gulf of Mexico). This is the first elucidated aporocotylid life cycle that includes a chondrichthyan definitive host or a bivalve intermediate host. The new species undergoes asexual reproduction within the gonad of the variable coquina clam before maturing in the heart of the lesser electric ray. These adults and cercariae had identical 28S, 18S, and ITS2 nucleotide sequences. The new genus is similar to Ogawaia Cutmor et al., 2018 by having an i...

Although we report an increased rate of grade (G) 2 or greater radiation dermatitis (RD), predominantly driven by G2 toxicity, we do not describe a doubling in the overall rate of RD seen in patients with breast cancer undergoing adjuvant proton pencil-beam scanning (PBT). We advise counseling patients of the potential for increased dermatologic toxicity, though this should not affect modality selection, considering a very low number of patients experienced G3 to G4 RD.1Although it is notable that this increased toxicity occurs in the absence of bolus, we do not conclude that PBT should be used in lieu of photon radiation ...

Authors: von Csiky-Sessoms S Abstract A 42-year-old male with skin type I and a history of rosacea and eczema presented with crusting, erythema, and pustules distributed on the left oral commissure. Angular cheilitis was diagnosed and regular petrolatum use recommended until resolution of the lesion. Eight days later, with no improvement in symptoms, fungal and bacterial cultures were performed which resulted in the growth of cutibacterium acnes, a variant of p. acnes.

Authors: Ewy S, Pham H, Quan K, Su B, Tachdjian R Abstract Bullous pemphigoid (BP) is a rare blistering skin disease that is commonly treated with corticosteroids and immunosuppressive agents. Here, we present a 74-year-old woman with severe BP following a leg fracture who was successfully treated with omalizumab. We started her on a regimen of omalizumab 300 mg subcutaneously every 4 weeks, and within a week she reported significantly decreased pain and faster healing time of lesions. Incidentally, bilateral erythematous, non-blistering dermatitis developed 5 centimeters distal to the injection sites within a week...

Authors: Tanis R, Ferenczi K, Payette M Abstract Prurigo nodularis (PN) is a disease in which chronic scratching and picking of the skin due to intense pruritis results in papulonodules, notably in areas that are accessible to the patient. The pathophysiology is hypothesized to be mediated by a Th2 helper cell response, similar to that seen in atopic dermatitis, therefore, treatment of PN with dupilumab would be expected to elicit a therapeutic response. We demonstrated that treatment of PN with dupilumab significantly decreased pruritis and the size and number of new lesions after 2 months of treatment. J Drugs D...

Publication date: Available online 30 January 2019Source: Veterinary ParasitologyAuthor(s): David W. Ramilo, Carla Monteiro, Marrion Carreira, Isabel Pereira da Fonseca, Luís CardosoAbstractTrombiculids parasitize a wide variety of terrestrial vertebrates, including domestic animals, throughout the world. They are parasites only during their larval stages, causing several dermatological lesions on their hosts, such as acute dermatitis, erythema, excoriation, erosion, papules, crusts and alopecia on the ear margins, face, interdigital spaces and abdomen. Neotrombicula is one of the several genera in Trombiculidae fam...

This study reveals disparate results in terms of dog exposure to fleas and ticks in the studied communities, which may be related to factors such as the owners’ capability/willingness to afford the use of ectoparasiticides on their dogs and level of restriction. Further research is needed to establish the relationship between dog owners’ socioeconomic situation and the level of exposure to ectoparasites and their transmitted pathogens.

Abstract A 70-year-old man was referred by his rheumatologist to our dermatology clinic for evaluation of dermatitis on his right arm that appeared 3 months earlier. The skin lesion was asymptomatic and the patient denied current systemic symptoms, including fever, chills, and joint pain; however, 10 months prior to this presentation he experienced arthritis in the left knee. At that time, Borrelia serology revealed positive IgG (6.07;

CONCLUSIONS: Clinical diagnosis of PNGD is difficult, and is based mainly on the histopathological picture. Systemic therapy is incorporated mainly due to the systemic disease. The patient requires further observation in the direction of associated systemic disorders. PMID: 27294654 [PubMed - in process]
