Summary
Dermatomyositis (DM) is increasingly diagnosed, often involving systemic issues and new myositis-specific antibodies. Early diagnosis is crucial for managing cancer risk and preventing irreversible muscle damage.
Area of Science:
- Rheumatology
- Dermatology
- Internal Medicine
Background:
- Dermatomyositis (DM) prevalence is 6-7 per 100,000 annually.
- Increasing incidence and systemic involvement necessitate updated overviews.
- Advances in myositis-specific antibodies (MSA) impact diagnosis and management.
Purpose of the Study:
- To provide a compact overview of adult dermatomyositis.
- To describe clinical, dermatological, and systemic manifestations.
- To present diagnostic and therapeutic strategies based on current guidelines and literature.
Main Methods:
- Literature review and synthesis of current evidence.
- Analysis of diagnostic procedures for dermatomyositis.
- Integration of German S2k guidelines for therapeutic regimens.
Main Results:
- DM presents a spectrum of dermatological and systemic symptoms.
- Early diagnosis is vital, as approximately 30% of DM patients have associated tumors.
- Etiopathology often involves pulmonary fibrosis and potential for irreversible myositis-induced muscle damage.
Conclusions:
- Clinical signs and serological markers are key for assessing DM extent.
- Accurate interpretation guides further diagnostics, prognosis, and therapy selection.
- This overview emphasizes timely diagnosis and comprehensive management of dermatomyositis.

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Myocarditis is an inflammation of the heart muscle. The symptoms vary widely, encompassing asymptomatic presentations to severe, acute manifestations.Clinical PresentationAsymptomatic cases: In some instances, myocarditis may be asymptomatic, with the infection resolving without intervention. These cases often go undetected unless discovered incidentally through diagnostic imaging or tests conducted for other reasons.General Early Symptoms: Early symptoms of myocarditis are non-specific and can...

Myocarditis is inflammation of the myocardium, which is the muscular layer of the heart.EtiologyMyocarditis has a diverse etiology, including a wide range of infectious and non-infectious causes:Infectious CausesViral: Common viruses include Coxsackie A and B, adenovirus, parvovirus B19, enteroviruses, and influenza A.Bacterial: Examples include infections caused by Streptococcus, Staphylococcus, and Mycoplasma species.Rickettsial: Infections like Rocky Mountain spotted fever can result in...

Myocarditis: Comprehensive Medical ManagementMyocarditis, the heart muscle inflammation, requires a comprehensive medical management strategy that addresses the underlying cause, provides supportive care, manages symptoms, and reduces cardiac workload.Infections and Autoimmune CausesAdminister appropriate antimicrobial therapy when an infectious agent causes myocarditis. For instance, penicillin treats infections caused by Group A Streptococcus. In cases where autoimmune processes are...

Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen...

01:20Myasthenia Gravis: Overview and Treatment
2.5K
Myasthenia gravis is a neuromuscular transmission disorder characterized by weakness and increased fatigability of skeletal muscles. It is an autoimmune disease affecting approximately one in 2000 people, where antibodies against the α1 subunit of nicotinic acetylcholine receptors are produced.
These antibodies interfere with the function of the nicotinic receptors in three ways: by binding to the receptor and disrupting acetylcholine binding; by causing cross-linking of receptors which...
