Summary
Juvenile dermatomyositis (JDM) is a rare autoimmune disease in children. This study reviewed seven Tunisian cases, highlighting diagnostic challenges and varied treatment outcomes, including corticosteroid resistance and relapse.
Area of Science:
- Pediatrics
- Rheumatology
- Dermatology
Background:
- Juvenile dermatomyositis (JDM) is the primary autoimmune inflammatory myopathy in children.
- Early diagnosis and management are crucial for improving outcomes in JDM patients.
Purpose of the Study:
- To describe the diagnostic features and management strategies for juvenile dermatomyositis.
- To analyze treatment outcomes and challenges in a cohort of Tunisian children with JDM.
Main Methods:
- Retrospective case series of seven patients diagnosed with JDM between 1998 and 2019.
- Review of patient records including clinical presentation, diagnostic findings (skin, muscle enzymes, EMG), and treatment regimens.
Main Results:
- All seven patients presented with skin manifestations; four had proximal muscle weakness.
- Elevated muscle enzymes and myopathic EMG findings were observed in affected patients.
- Treatment with oral corticosteroids, often combined with other therapies, yielded variable results, including good outcomes, relapses, and corticosteroid resistance.
Conclusions:
- Juvenile dermatomyositis presents with characteristic skin and muscle involvement.
- Management requires a multimodal approach, and outcomes can be unpredictable, necessitating further research into optimal therapeutic strategies.

Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.

01:15Myasthenia Gravis: Diagnostic Tests
699
Myasthenia gravis is an autoimmune condition affecting neuromuscular transmission, causing generalized weakness in skeletal muscles. Initial diagnoses rely on patients' signs, symptoms, and medical history. The challenge lies in distinguishing myasthenia from other muscular dystrophies. An important diagnostic feature is the significant improvement of symptoms after administering anticholinesterase inhibitors.

1.3K
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...

Upon diagnosis, managing Inflammatory Bowel Disease (IBD) involves addressing several crucial aspects. The primary goals include resting the bowel, correcting malnutrition, and providing symptomatic relief. Resting the bowel may consist of medications to reduce inflammation and promote healing. Correcting malnutrition is essential, often requiring dietary adjustments and nutritional supplements. Symptomatic relief aims to ease pain, diarrhea, and other discomforts in IBD.

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...
