What is Carvajal syndrome?
What is Carvajal syndrome?
Carvajal Syndrome. A 6-year-old male term child, born of second degree consanguineous marriage presented with thickening of palms and soles since 1 year of old. There was a history of recurrent fever with cough, loss of appetite, and exertional breathlessness for 2 months. Developmental history was normal.
What is the pathophysiology of carajal syndrome?
Carajal syndrome, a variant of Naxos disease (Naxos arrhythmogenic cardiocutaneous syndrome), associates woolly hair and palmoplantar keratoderma with an extreme type of left dominant arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D), initially characterized as dilated cardiomyopathy.
What is Naxos disease and Carvajal syndrome?
Naxos disease and Carvajal syndrome: cardiocutaneous disorders that highlight the pathogenesis and broaden the spectrum of arrhythmogenic right ventricular cardiomyopathy Naxos disease is a recessive association of arrhythmogenic right ventricular cardiomyopathy (ARVC) with wooly hair and palmoplantar keratoderma or similar skin disorder.
What restrictions are required for individuals with Carvajal syndrome?
Restriction of athletic activity is required for all individuals with Carvajal phenotype. Carvajal syndrome is a variant of Naxos cardiocutaneous syndrome due to recessive desmoplakin mutations, its principal sign being the early and severe left ventricular involvement, with ventricular arrhythmias and premature heart failure.
Carvajal syndrome is characterized by woolly hair, striate palmoplantar keratoderma and left-sided ventricular cardiomyopathy leading to sudden cardiac death. It is inherited as autosomal recessive disorder due to defect in desmoplakin gene.
What is Epsilon wave?
Epsilon wave definition. The epsilon (ε) wave can be defined as an electric signal of depolarization observed between the end of the QRS complex and the beginning of the T wave.
Who discovered ARVD?
Cardiovascular diseases account for 2.1 sudden deaths per 100 000 athletes per year, out of which ARVD/C accounts for 22.4% of deaths in the same region of Italy. Since the first description of the disease in 1977 by Fontaine et al, there have been considerable advancements in our understanding of ARVD.
Can keratoderma be cured?
Inherited palmoplantar keratodermas are not curable but symptoms can be controlled. The aim of treatment is to reduce the thickness of the skin and to soften the skin.
How do you get rid of keratoderma?
The following treatments soften the thickened skin and makes it less noticeable.
- Emollients.
- Keratolytic agents (eg, 6% salicylic acid, 70% propylene glycol, 30% water)
- Topical retinoids.
- Topical vitamin D ointment (calcipotriol)
- Oral retinoids (acitretin)
What is associated with Osborn or J waves on the EKG?
The Osborn wave (J wave) is a positive deflection seen at the J point in precordial and true limb leads. It is most commonly associated with hypothermia.
What is Osborn wave on ECG?
The “J wave” (also referred to as “the Osborn wave,” “the J deflection,” or “the camel’s hump”) is a distinctive deflection occurring at the QRS-ST junction. In 1953, Dr. John Osborn described the “J wave” as an “injury current” resulting in ventricular fibrillation during experimental hypothermia.
