**Question:** False about scurvy

A. Scurvy is caused by a deficiency of vitamin C.
B. Symptoms of scurvy include easy bruising and gum inflammation.
C. Scurvy was eradicated in the 19th century due to improved shipbuilding and navigation.
D. Treatment for scurvy involves oral administration of vitamin C supplements.

**Core Concept:** Scurvy is a disease resulting from vitamin C deficiency. Vitamin C, also known as ascorbic acid, is essential for collagen synthesis, which is crucial for wound healing and maintaining connective tissue integrity.

**Why the Correct Answer is Right:**
A. Scurvy is indeed caused by a deficiency of vitamin C, which is essential for collagen synthesis and immune system function.
B. The symptoms mentioned, such as easy bruising and gum inflammation, are indeed common manifestations of scurvy due to impaired collagen synthesis and connective tissue repair.
C. While it is true that scurvy was less common in the 19th century due to improved shipbuilding and navigation, the disease still exists today, particularly among vulnerable populations.
D. Treatment for scurvy involves administering vitamin C supplements orally to replenish the deficient vitamin C levels and promote collagen synthesis.

**Why Each Wrong Option is Incorrect:**
A. False: Scurvy is caused by vitamin C deficiency, not a deficiency of another substance.
B. False: The symptoms mentioned are not specific to scurvy and could be caused by other conditions as well.
C. False: Scurvy still exists, particularly in marginalized populations, and understanding its persistence is crucial for practicing physicians.
D. False: The correct treatment for scurvy is to supplement with vitamin C, not just administer oral supplements.

**Clinical Pearl:**
Scurvy is a preventable disease that can affect individuals consuming inadequate vitamin C-rich foods. Early diagnosis and treatment with vitamin C supplements can prevent severe complications, such as skin ulcers, joint pain, and even death. Ensuring a balanced diet, including fruits and vegetables, is crucial for maintaining optimal vitamin C levels and preventing scurvy.
