The Tel-Hashomer diagnostic criteria calculator for familial Mediterranean fever (FMF) evaluates the likelihood of a diagnosis based on specific clinical inputs. The calculator considers six important factors: recurrent febrile episodes with serositis peritonitis, synovitis, or pleuritis; AA-type amyloidosis without a predisposing disease; favorable response to continuous colchicine treatment; recurrent febrile episodes; erysipelas-like erythema; and familial Mediterranean fever in a first-degree relative.

Each factor is assigned a score as follows:

- Recurrent febrile episodes with serositis peritonitis, synovitis, or pleuritis: 3 points
- AA-type amyloidosis without a predisposing disease: 3 points
- Favorable response to continuous colchicine treatment: 3 points
- Recurrent febrile episodes: 1 point
- Erysipelas-like erythema: 1 point
- Familial Mediterranean fever in a first-degree relative: 1 point

The total score is calculated by summing the points for each positive factor. However, if both "recurrent febrile episodes" and "recurrent febrile episodes with serositis peritonitis, synovitis, or pleuritis" are present, the score for "recurrent febrile episodes" is not counted to avoid double-counting, deducting 1 point from the total score.

Once the total score is determined, it is interpreted as follows:

- A score of 5 or more indicates the criteria for a definitive diagnosis of FMF are met.
- A score of exactly 4 suggests the criteria for a probable diagnosis.
- A score below 4 means the diagnostic criteria are not met.

The Tel-Hashomer diagnostic criteria is a clinical calculator used for the diagnosis of Familial Mediterranean Fever (FMF). FMF is a genetic disorder that causes recurrent episodes of fever and inflammation, primarily affecting populations of Mediterranean descent such as Armenians, Arabs, Turks, and Jews. 

The Tel-Hashomer criteria are divided into two categories: major and minor. Major criteria include typical attacks of fever and serositis, response to colchicine treatment, and amyloidosis of AA type without a known cause. Minor criteria include recurrent febrile episodes, erysipelas-like erythema, and a positive family history of FMF. 

The clinical utility of this calculator is to aid in the diagnosis of FMF, particularly in cases where genetic testing is inconclusive or unavailable. It is also used to guide treatment decisions, as a positive diagnosis may warrant the use of colchicine, a drug that can prevent FMF attacks and complications.

There are no specific exclusion criteria for the use of the Tel-Hashomer diagnostic criteria. However, it should be noted that this calculator is less effective in populations where FMF is less common, and it may not be as accurate in diagnosing atypical or milder forms of the disease.

The Simplified Livneh diagnostic criteria for familial Mediterranean fever (FMF) calculator involves evaluating specific symptoms and responses to treatment, assigning numerical scores to each, to determine if diagnostic criteria for FMF are met. This diagnostic tool takes information on eight possible factors:

- Typical attacks of generalized peritonitis
- Typical attacks of unilateral pleuritis or pericarditis
- Typical attacks of monoarthritis (hip, knee, ankle)
- Typical attacks of fever alone
- Incomplete abdominal attacks
- Incomplete thoracic or articular attacks, or both
- Exertional leg pain
- Favorable response to colchicine

Each factor is a yes or no question, indicating the presence or absence of a symptom or response.

The scoring system provides:

- 2 points for each of the first five factors (typical peritonitis, pleuritis or pericarditis, monoarthritis, fever, incomplete abdominal attacks).
- 1 point for the presence of incomplete thoracic or articular attacks, exertional leg pain, or a favorable response to colchicine.

The scores across these factors are summed to yield a total score ranging from 0 to 13.

Interpretation is straightforward:

- A total score of 2 or more indicates that the diagnostic criteria for familial Mediterranean fever are met.
- A total score below 2 suggests that the diagnostic criteria are not met.

This systematic scoring method quantifies symptoms and responses, helping to assess the likelihood of FMF in a structured manner.

The Simplified Livneh Diagnostic Criteria for Familial Mediterranean Fever (FMF) is a clinical calculator used to diagnose Familial Mediterranean Fever, a hereditary inflammatory disorder. This calculator is applicable to individuals of all ages who present with recurrent febrile episodes and are suspected of having FMF, particularly those of Mediterranean descent, including Armenians, Arabs, Turks, and Jews.

The Simplified Livneh Diagnostic Criteria for FMF is clinically useful in identifying patients with FMF, which can help guide appropriate treatment and management strategies. It takes into account factors such as the frequency and duration of fever episodes, presence of specific symptoms like abdominal pain or arthritis, response to colchicine treatment, and family history of FMF.

Exclusion criteria for the use of this calculator include the presence of other conditions that could explain the patient's symptoms, such as infections, malignancies, or other rheumatic diseases. Additionally, it may not be as accurate in populations where FMF is less common.

The evaluator for childhood familial Mediterranean fever (FMF) explores two key aspects: symptoms and family history. These inputs help determine the likelihood of meeting the diagnostic criteria for FMF.

How the evaluation works:

- MoreThanOrEqual3AttacksOfTheFollowingEachLasting672Hours: Users are asked if they've had at least three episodes of specific symptoms, each lasting between 6 and 72 hours:
  - Fever (axillary temperature above 38 degrees C) earns 1 point
  - Abdominal pain, chest pain, and arthritis each earn 1 point

- FamilyHistoryOfFamilialMediterraneanFever: Users indicate if FMF runs in the family:
  - A 'Yes' response gains 1 point
  - A 'No' response gains 0 points

The evaluator sums these points for a total score. Interpretation is straightforward:

- A score of 2 or higher suggests the diagnostic criteria for FMF are met, indicating a higher probability of the condition.
- A score below 2 suggests the criteria are not met, indicating a lower probability.

This process quickly guides users by tallying points from their provided information and interpreting the result to assess the likelihood of meeting FMF diagnostic criteria.

The Yalcinkaya-Ozen's diagnostic criteria is a clinical calculator specifically designed for the diagnosis of Familial Mediterranean Fever (FMF) in children. Familial Mediterranean Fever is a genetic autoinflammatory disorder that causes recurrent fevers and painful inflammation of the abdomen, chest, and joints. This calculator is particularly useful in pediatric populations where FMF is suspected, especially in regions where the disease is prevalent such as the Mediterranean region.

The Yalcinkaya-Ozen's diagnostic criteria includes parameters such as typical clinical symptoms, response to colchicine treatment, and presence of MEFV mutations. It helps clinicians to establish a diagnosis of FMF, particularly in cases where genetic testing is not available or inconclusive. 

The exclusion criteria for the use of this calculator would be the presence of other diseases that can mimic FMF symptoms, such as infections, malignancies, or other rheumatic diseases. Also, it may not be as applicable in populations where FMF is rare.
