Hyperesthesia is a condition that involves an abnormal increase in sensitivity to stimuli of the sense. Stimuli of the senses can include sound that one hears, foods that one tastes, textures that one feels, and so forth. Increased touch sensitivity is referred to as "tactile hyperesthesia", and increased sound sensitivity is called "auditory hyperesthesia". In the context of pain hyperaesthesia can refer to an increase in sensitivity where there is both allodynia and hyperalgesia.In psychology, Jeanne Siaud-Facchin uses the term by defining it as an "exacerbation des sens": 37  that characterizes gifted individuals: for them, the sensory information reaches the brain much faster than the average, and the information is processed in a significantly shorter time. Other animals
Feline hyperesthesia syndrome is an uncommon but recognized condition in cats, particularly Siamese, Burmese, Himalayan, and Abyssinian cats. It can affect cats of all ages, though it is most prevalent during maturity. Detection can be somewhat difficult as it is characterized by brief bursts of abnormal behavior, lasting around a minute or two. One of its symptoms is also found in dogs that have canine distemper disease (CD) caused by canine distemper virus (CDV). See also

Conditions
The following conditions are typically included in the group of seronegative spondylarthropathies:

Some sources also include Behçets disease and Whipples disease. Common characteristics
These diseases have the following conditions in common:

Seronegative (i.e. rheumatoid factor is not present)
They are in relation to HLA-B27
Inflammatory axial arthritis, generally sacroiliitis and spondylitis
Oligoarthritis, generally with asymmetrical presentation
Enthesitis (inflammation of the entheses, the sites where tendons or ligaments insert into the bone. ), e.g. Plantar fasciitis, Achilles tendinitis, costochondritis. Familial aggregation occurs
Extra-articular features, such as involvement of eyes (anterior uveitis), skin, genitourinary tract, and aortic regurgitation
Overlap is likely between several of the causative conditions

Classification
Assessment of Spondylarthritis International Society (ASAS criteria) is used for classification of axial spondyloarthritis (to be applied for patients with back pain greater than or equal to 3 months and age of onset less than 45 years). It is of two broad types:
Sacroiliitis on imaging plus 1 SpA feature, or
HLA-B27 plus 2 other SpA featuresSacroiliitis on imaging:
Active (acute) inflammation on MRI highly suggestive of SpA-associated sacroiliitis and/or
Definite radiographic sacroiliitisSpA features:
Inflammatory back pain
Arthritis
Enthesitis
Anterior uveitis
Dactylitis
Psoriasis
Crohns disease or ulcerative colitis
Good response to NSAIDs
Family history of SpA
HLA-B27
Elevated CRP

Treatment
Many patients have more than one of the spondyloarthritis disease manifestations. Some immunosuppressive drugs have shown efficacy in more than one of the diseases, e.g. tumor necrosis factor (TNF) inhibitors. But some of the immunosuppressive drugs are particularly effective for a specific inflamed tissue and approved in only one or two of the disease entities, so an interdisciplinary approach is required. Epidemiology
Worldwide prevalence of spondyloarthropathy is approximately 1.9%. References
