Rett syndrome (RTT) is a severe neurodevelopmental disease that affects approximately 1 in 10,000 live female births and is often caused by mutations in Methyl-CpG-binding protein 2 (MECP2).
Criteria
Diagnostic Criteria for Marfan Syndrome (MFS)
Marfan syndrome is currently diagnosed using criteria based on an evaluation of the family history, molecular data, and 6 organ systems.
ILAR Classification Criteria for Juvenile Idiopathic Arthritis (JIA)
Juvenile idiopathic arthritis is a heterogeneous group of diseases characterised by arthritis of unknown origin with onset before age of 16 years.
Clinical Criteria for the Diagnosis of Acute Bacterial Sinusitis
Acute bacterial sinusitis in children is diagnosed on the basis of the history, with the use of the criteria. Imaging studies (plain-film radiography, computed tomography [CT], magnetic resonance imaging [MRI], and ultrasonography) show signs of sinus inflammation but are not recommended in patients with uncomplicated infection, given the low specificity of these studies.
Diagnostic Criteria for Difficult-to-Control Asthma
The difficult-to-control asthma can be defined as that which is inadequately or poorly controlled despite an appropriate therapeutic strategy that is adjusted to clinical severity.
Diagnostic Criteria for Alopecia Areata
Alopecia areata is manifested as the loss of hair in well-circumscribed patches of normal-appearing skin, most commonly on the scalp and in the region of the beard. The onset is typically rapid, and the disease can progress to the point where all the hair is lost on the scalp (alopecia areata totalis) or even on the whole body (alopecia areata universalis).
Diagnostic Criteria for Diabetic Sensorimotor Polyneuropathy (DSPN)
The Diabetic Sensorimotor Polyneuropathy (DSPN) is a symmetrical, length-dependent sensorimotor polyneuropathy attributable to metabolic and microvessel alterations as a result of chronic hyperglycemia exposure (diabetes) and cardiovascular risk covariates.
Diagnostic Criteria for Autistic Disorder
The American Psychiatric Association’s Diagnostic and Statistical Manual-IV, Text Revision (DSM-IV-TR) provides standardized criteria to help diagnose Autism Spectrum Disorders (ASDs).
Classification for Chagas Cardiomyopathy
Chagas’ disease is caused by a protozoan parasite, Trypanosoma cruzi, that is transmitted to humans through the feces of infected bloodsucking insects in endemic areas of Latin America, or occasionally by nonvectorial mechanisms, such as blood transfusion. Cardiac involvement, which typically appears decades after the initial infection, may result in cardiac arrhythmias, ventricular aneurysm, congestive heart failure, thromboembolism, and sudden cardiac death.
Diagnostic Criteria for Chronic Inflammatory Demyelinating Polyneuropathy (CIDP)
Classic chronic inflammatory demyelinating polyneuropathy (CIDP) is characterized by the occurrence of symmetrical weakness in both proximal and distal muscles that progressively increases for more than two months (setting this condition apart from the Guillain–Barré syndrome, which is self-limited). The condition is associated with impaired sensation, absent or diminished tendon reflexes, an elevated cerebrospinal fluid protein level, demyelinating nerve-conduction studies, and signs of demyelination in nerve-biopsy specimens. The course can be relapsing or chronic and progressive, the former being much more common in young adults.
