Case ReportsFish tank granuloma not associated to Mycobacterium marinum but to Microbacterium paraoxydans.
Fish tank granuloma has traditionally been associated with Mycobacterium marinum. We report the case of a 54 old-year woman that worked in a freshwater fish pet store and developed a skin ulcer in a hand finger with a suppurative granuloma secondary to Microbacterium paraoxydans. ⋯ She evolved satisfactorily after receiving a sequential treatment with beta-lactams and linezolid. To our knowledge, it is the first known description of this type.

Observational Study[Biopsychosocial Factors Influencing Mortality and Functional Recovery in COVID-19 Patients Undergoing Prone Positioning: A Prospective Observational Study].
Patients placed in a prone position due to COVID-19 present a more severe disease, longer stay in ICU and have more significant complications associated with positioning than other patients. ⋯ The survival and functional prognosis of patients with severe COVID-19 can be predicted early through a biopsychosocial evaluation of their characteristics. Intrahospital actions could improve functional recovery in ADL in the short term in critically ill patients surviving COVID-19.

Case Reports[Polymorphic lymphoproliferative disorder, lymphomatoid granulomatosis-type, in a patient with iatrogenic immunosuppression, an unusual entity].
Patients with immunodeficiency, whether congenital or acquired, have a significantly higher incidence of malignancies, especially mature lymphoid neoplasms and lymphoproliferative disorders. We present the case of a 50-year-old patient with a history of dermatomyositis and antisynthetase syndrome on immunosuppressive therapy, who consulted due to increased volume of the lacrimal gland in the upper left eyelid, associated with weight loss and night sweats. He was admitted for an elective biopsy. ⋯ In this scenario, an infectious, neoplastic, or rheumatological etiology was considered a differential diagnosis, especially in the context of our patient. Finally, the biopsies evidenced extensive necrosis with angiocentric and angiodestructive lymphoid infiltration associated with positive EBV. After extensively reviewing the symptoms, histology, and new classifications of mature B-lymphoid neoplasms, the diagnosis of polymorphic B-lymphoproliferative disorder, lymphomatoid granulomatosis-type was made, an uncommon entity rarely associated with iatrogenic immunosuppression.

Case Reports[Disappearing bone disease of the shoulder (Gorham-Stout Syndrom)].
The spontaneous disappearance of a segment of bone in a short period without the existence of a tumoral disease that justifies it is an exceptional event. We report the case of an older adult in whom the upper epiphysis of the right humerus and part of the acromion disappeared in a period of 3 weeks in the absence of a malignant tumor. ⋯ This disorder was first reported in 1838 and in 1955 it was established as a specific disease by Gorham and Stout. Since then, it has been named in their honor.

[Prevalence of frailty in the different regions of Chile: A cross-sectional analysis of the National Health Survey 2016-2017].
Frailty is an increasingly frequent geriatric syndrome in the population; however, its regional prevalence in Chile has not been quantified. ⋯ The prevalence off rail individuals was higher in the central zone of Chile, it increased as age increased, and it was higher in women with a lower educational level.
