Pyomyositis Secondary to Localized Cellulitis in a Dermatomyositis Patient: A Case Report and Review of Infectious Complications in Dermatomyositis
Clin Cosmet Investig Dermatol. 2023 Aug 11;16:2201-2209. doi: 10.2147/CCID.S417772. eCollection 2023.ABSTRACTDermatomyositis (DM) is an autoimmune disorder characterized by proximal muscle weakness and distinct cutaneous features. Unfortunately, infection is a frequent and potentially life-threatening complication in patients with DM. Here, we present a case of pyomyositis in a patient with DM resulting from localized cellulitis. The patient also presented with subcutaneous calcification nodules and dermatomyositis-associated lipodermatosclerosis nodules. To our knowledge, there have been no reports of pyomyositis in patie...

First study demonstrating speckle tracking echocardiography has prognostic value in patients with idiopathic inflammatory myopathies
AbstractTo measure left ventricular (LV) global longitudinal strain (GLS) using speckle tracking echocardiography in idiopathic inflammatory myopathy (IIM) patients and to determine whether the LV GLS predicts outcomes in those patients. Prospective study consisted of a cross-sectional phase with 61 IIM patients and 32 individuals without IIM and longitudinal phase, in which patients were divided into two subgroups: 26 with reduced LV GLS and 35 with normal LV GLS; patients were followed for a mean of 25 months, and the occurrence of cardiovascular events and criteria for IIM activity were compared. The mean LV GLS (18.5...

The ever wider clinical spectrum of RMND1-related disorders and limitedness of phenotype-based classifications
J Mol Med (Berl). 2023 Aug 16. doi: 10.1007/s00109-023-02356-x. Online ahead of print.ABSTRACTRMND1 has been identified as a mitochondriopathy-associated gene less than 12 years ago. The most common phenotype related to this gene is an early onset, severe form of encephalomyopathy that leads to death in a medium time of three years after birth. However, milder and later onset presentations have been reported in some individuals, including two in whom the mitochondriopathy was identified at ~ 40 years of age, and the early onset presentations have been the object of no reports in those who survived beyond age 10. It is thus...

Macronodular adrenal hyperplasia causing Cushing's syndrome due to ARMC5 gene mutation.
Orv Hetil. 2023 Aug 13;164(32):1271-1277. doi: 10.1556/650.2023.32817. Print 2023 Aug 13.ABSTRACTOur 69-year-old female patient was investigated for a 20 kg weight gain over 2 years. The patient's medical history included hypertension, hyperuricemia, bilateral cataract surgery and musculosceletal complaints. Diabetes mellitus was not found. Physical examination revealed abdominal obesity, proximal myopathy and atrophic, vulnerable skin. The "overnight", low-dose and long, low-dose dexamethasone suppression tests indicated autonomous cortisol overproduction (plasma cortisol level: 172.6 and 153.2 nmol/L, cut-off: 50 nmol/L)...

Generation of CHOPi012-A iPSC line from a patient with visceral myopathy-related chronic intestinal pseudo-obstruction
Stem Cell Res. 2023 Aug 1;71:103176. doi: 10.1016/j.scr.2023.103176. Online ahead of print.ABSTRACTVisceral myopathies are debilitating conditions characterized by dysfunction of smooth muscle in visceral organs (bowel, bladder, and uterus). Individuals affected by visceral myopathy experience feeding difficulties, growth failure, life-threatening abdominal distension, and may depend on intravenous nutrition for survival. Unfortunately, our limited understanding of the pathophysiology of visceral myopathies means that current therapies remain supportive, with no mechanism-based treatments. We developed a patient-derived iP...
