RESUMEN
Continuous glucose monitoring (CGM) systems are of great value for patients with disorders of impaired glucose homeostasis, including glycogen storage diseases. We report on an 8-year-old girl with glycogen storage disease type 9b who developed severe allergic contact dermatitis to two different continuous glucose monitoring systems, FreeStyle® Libre and Dexcom® G6. Our case highlights the impact of sensitization for pediatric patients, the urgent need for open labeling of components by pharmaceutical and device manufacturers, and the need for avoidance of skin sensitizers in medical devices.

Syndromes associated with concurrent skin and joint inflammation frequently pose a therapeutic challenge for both dermatologists and rheumatologists. In part 1 of this review, we discussed psoriatic arthritis as well as the autoinflammatory disorders SAPHO syndrome, Still's disease and Behçet's disease. Part 2 will address rheumatoid arthritis, reactive arthritis, Reiter's syndrome and Lyme borreliosis. In addition, we will discuss dermatomyositis and lupus erythematosus, two common autoimmune disorders that frequently present with both cutaneous and joint involvement. For each of the aforementioned disorders, we will highlight aspects of epidemiology, pathogenesis, clinical presentation, diagnosis and treatment.

The coincidence of skin and joint inflammation poses a challenge for both dermatologists and rheumatologists. Adequate management of such disorders requires that physicians of both specialties have sound knowledge of the other discipline. In case of suspected joint involvement, familiarity with the diagnostic options available to rheumatologists enables dermatologists to selectively refer their patients for a rheumatology consult. The objective of the present review is to familiarize the reader with the stepwise diagnostic workup performed by rheumatologists today, including laboratory tests, musculoskeletal ultrasound, X-ray studies, and magnetic resonance imaging. Subsequently, we will discuss a number of disorders characterized by the concurrence of skin and joint inflammation, highlighting aspects of epidemiology, etiology and pathogenesis, clinical presentation, diagnosis and treatment. These disorders include psoriatic arthritis as well as autoinflammatory disorders such as SAPHO syndrome, Still's disease and Behçet's disease.

Anaplasma phagocytophilum is a Gram-negative obligate intracellular bacterium that replicates in neutrophils. It is transmitted via tick-bite and causes febrile disease in humans and animals. Human granulocytic anaplasmosis is regarded as an emerging infectious disease in North America, Europe and Asia. However, although increasingly detected, it is still rare in Europe. Clinically apparent A. phagocytophilum infections in animals are mainly found in horses, dogs, cats, sheep and cattle. Evidence from cross-infection experiments that A. phagocytophilum isolates of distinct host origin are not uniformly infectious for heterologous hosts has led to several approaches of molecular strain characterization. Unfortunately, the results of these studies are not always easily comparable, because different gene regions and fragment lengths were investigated. Multilocus sequence typing is a widely accepted method for molecular characterization of bacteria. We here provide for the first time a universal typing method that is easily transferable between different laboratories. We validated our approach on an unprecedented large data set of almost 400 A. phagocytophilum strains from humans and animals mostly from Europe. The typability was 74% (284/383). One major clonal complex containing 177 strains was detected. However, 54% (49/90) of the sequence types were not part of a clonal complex indicating that the population structure of A. phagocytophilum is probably semiclonal. All strains from humans, dogs and horses from Europe belonged to the same clonal complex. As canine and equine granulocytic anaplasmosis occurs frequently in Europe, human granulocytic anaplasmosis is likely to be underdiagnosed in Europe. Further, wild boars and hedgehogs may serve as reservoir hosts of the disease in humans and domestic animals in Europe, because their strains belonged to the same clonal complex. In contrast, as they were only distantly related, roe deer, voles and shrews are unlikely to harbor A. phagocytophilum strains infectious for humans, domestic or farm animals.
