Overview

There is no established system for the classification of [disease name].

OR

[Disease name] may be classified according to [classification method] into [number] subtypes/groups: [group1], [group2], [group3], and [group4].

OR

[Disease name] may be classified into [large number > 6] subtypes based on [classification method 1], [classification method 2], and [classification method 3]. [Disease name] may be classified into several subtypes based on [classification method 1], [classification method 2], and [classification method 3].

OR

Based on the duration of symptoms, [disease name] may be classified as either acute or chronic.

OR

If the staging system involves specific and characteristic findings and features: According to the [staging system + reference], there are [number] stages of [malignancy name] based on the [finding1], [finding2], and [finding3]. Each stage is assigned a [letter/number1] and a [letter/number2] that designate the [feature1] and [feature2].

OR

The staging of [malignancy name] is based on the [staging system].

OR

There is no established system for the staging of [malignancy name].

Classification

Hyponatremia is defined as serum sodium less than 135 mEq/L (mmol/L).There are different classifications of hyponatremia based on duration, severity, volume and sodium status and ADH level.

Hyponatremia is classified based on serum sodium level to:

• Mild : serum sodium 130– 135 mmol/L
• Moderate : serum sodium ≤125–129 mmol/L
• Severe: serum sodium <124 mmol/L

Classification based on duration:

• Hyperacute: develops in a few hours,excess water intake/impaired water excretion,runners,users of the recreational drug (Ecstasy)

• Acute: rapid onset <48 hours(some litreture )
• Chronic: gradual onset >48 hours, caused by chronic disease (including cardiac,renal, hepatic and other conditions)

classification based on ADH level:

• ↑ ADH:
• ↓ ADH:

• There is no established system for the classification of [disease name].

• [Disease name] may be classified according to [classification method] into [number] subtypes/groups:
  • [Group1]

• [Disease name] may be classified into [large number > 6] subtypes based on:
  • [Classification method 1]
