Bowen’s disease Clinical features
Bowen’s disease (BD) is the name given to an intra-epidermal carcinoma that usually presents as a slowly enlarging, erythematous, scaly plaque on the lower legs of fair-skinned older women but other sites can also be involved. It can be confused with eczema or psoriasis, but is usually asymptomatic and does not respond to topical glucocorticoids. It may also be hard to distinguish from superficial BCC. Transformation into SCC occurs in 3% or less

Granulomatous inflammation -
ব্যাখ্যা
Explanation :
Granulomatous inflammation is a form of chronic inflammation characterized by collections of activated macrophages, often with T lymphocytes, and sometimes associated with necrosis.
Granuloma formation is a cellular attempt to contain an offending agent that is difficult to eradicate. In this attempt there is often strong activation of T lymphocytes leading to macrophage activation, which can cause injury to normal tissues.
Epitheloid cell predominant.

Which type of diabetes is most likely to present with ketoacidosis?
ব্যাখ্যা
Answer: A
Explanation: Diabetic ketoacidosis (DKA) is most common in type 1 diabetes due to the absolute insulin deficiency. Davidson explains that without insulin, the body shifts to fat metabolism, producing ketones and leading to metabolic acidosis. Harrison adds that DKA can occur in type 2 diabetes under extreme stress, but it is far less common.

Myocardial contractility is best correlated with the intracellular concentration of?
ব্যাখ্যা
Contractility of myocardial cells depends on the intracellular [Ca2+], which is regulated by Ca2+ entry across the cell membrane during the plateau of the action potential and by Ca2+ uptake into and release from the sarcoplasmic reticulum (SR). Ca2+ binds to troponin C and removes the inhibition of actin–myosin interaction, allowing contraction (shortening) to occur.
