One research priority is to determine the role and nature of malignant hyperthermia in FSS. Such knowledge would benefit possible surgical candidates and the anaesthesiology and surgical teams who would care for them. MH may also be triggered by stress in patients with muscular dystrophies. Much more research is warranted to evaluate this apparent relationship of idiopathic hyperpyrexia, MH, and stress. Further research is wanted to determine epidemiology of psychopathology in FSS and refine therapy protocols.
YVS has been described relatively recently in the 1980s and since then less than 15 cases have been reported around the world. Many of the infants did not survive beyond one year of age.
Early intervention is considered important. For infants, breathing and feeding difficulties, are monitored. Therapies used are "symptomatic and supportive."
Patients must have early consultation with craniofacial and orthopaedic surgeons, when craniofacial, clubfoot, or hand correction is indicated to improve function or aesthetics. Operative measures should be pursued cautiously, with avoidance of radical measures and careful consideration of the abnormal muscle physiology in Freeman–Sheldon syndrome. Unfortunately, many surgical procedures have suboptimal outcomes, secondary to the myopathy of the syndrome.
When operative measures are to be undertaken, they should be planned for as early in life as is feasible, in consideration of the tendency for fragile health. Early interventions hold the possibility to minimise developmental delays and negate the necessity of relearning basic functions.
Due to the abnormal muscle physiology in Freeman–Sheldon syndrome, therapeutic measures may have unfavourable outcomes. Difficult endotracheal intubations and vein access complicate operative decisions in many DA2A patients, and malignant hyperthermia (MH) may affect individuals with FSS, as well. Cruickshanks et al. (1999) reports uneventful use of non-MH-triggering agents. Reports have been published about spina bifida occulta in anaesthesia management and cervical kyphoscoliosis in intubations.
Treatment usually involves plastic and reconstructive surgery. Surgery may be needed to correct undescended testes or hernias.
A number of features found with Nasodigitoacoustic syndrome can be managed or treated. Sensorineural hearing loss in humans may be caused by a loss of hair cells (sensory receptors in the inner ear that are associated with hearing). This can be hereditary and/or within a syndrome, as is the case with nasodigitoacoustic syndrome, or attributed to infections such as viruses. For the management of sensorineural hearing loss, hearing aids have been used. Treatments, depending upon the cause and severity, may include a pharmacological approach (i.e., the use of certain steroids), or surgical intervention, like a cochlear implant.
Pulmonary, or pulmonic stenosis is an often congenital narrowing of the pulmonary valve; it can be present in nasodigitoacoustic-affected infants. Treatment of this cardiac abnormality can require surgery, or non-surgical procedures like balloon valvuloplasty (widening the valve with a balloon catheter).
There is no known cure for Winchester syndrome; however, there are many therapies that can aid in the treatment of symptoms. Such treatments can include medications: anti-inflammatories, muscle relaxants, and antibiotics. Many individuals will require physical therapy to promote movement and use of the limbs affected by the syndrome. Genetic counseling is typically prescribed for families to help aid in the understanding of the disease. There are a few clinical trials available to participate in. The prognosis for patients diagnosed with Winchester syndrome is positive. It has been reported that several affected individuals have lived to middle age; however,the disease is progressive and mobility will become limited towards the end of life. Eventually, the contractures will remain even with medical intervention, such as surgery.
Treatment is symptomatic, often addressing indicators associated with peripheral pulmonary artery stenosis. Laryngotracheal calcification resulting in dyspnea and forceful breathing can be treated with bronchodilators including the short and long-acting β2-agonists, and various anticholinergics. Prognosis is good, yet life expectancy depends on the severity and extent of diffuse pulmonary and arterial calcification.
Most patients with hyper IgE syndrome are treated with long-term antibiotic therapy to prevent staphylococcal infections. Good skin care is also important in patients with hyper IgE syndrome. High-dose intravenous gamma-globulin has also been suggested for the treatment of severe eczema in patients with HIES and atopic dermatitis.
Tetra-amelia syndrome has been reported in only a few families worldwide.
According to a 2011 study by Bermejo-Sanchez, amelia – that is, the lacking of one or more limbs – occurs in roughly 1 out of every 71,000 pregnancies.
In 2005, a patient with Winchester syndrome was shown to have mutations in the matrix metalloproteinase 2 ("MMP2") gene. A 2006 study showed other mutations found in the MMP2 gene. This has led to the belief that there are many similar diseases within this family of mutations. As of 2007, it was found that these mutations are also found in Torg and Nodulosis-arthropathy-osteolysis syndrome (NAO). This means that Torg, NAO, and Winchester syndrome are allelic disorders. In 2014, a new case of Winchester syndrome was reported. According to a recently published article, it was discovered that multicentric osteolysis, nodulosis, and arthropathy (MONA) and Winchester syndrome are different diseases. Mutations in MMPS and MT1-MMP result in similar but distinctly different "vanishing bone" syndromes.
The syndrome is named after Turkish (Asim Cenani) and German (Widukind Lenz) medical geneticists.
HIES was first described by Davis et al. in 1966 in two girls with red hair, chronic dermatitis, and recurrent staphylococcal abscesses and pneumonias. They named the disease after the biblical figure Job, whose body was covered with boils by Satan. In 1972, Buckley et al. described two boys with similar symptoms as well as coarse facies, eosinophilia, and elevated serum IgE levels. These two syndromes are thought to be the same and are under the broad category of HIES.
Coffin–Siris Syndrome is a rare genetic disorder that causes developmental delays and absent fifth finger and toe nails.
There had been 31 reported cases by 1991. The numbers of occurrence since then has grown and is reported to be around 80.
The differential includes Nicolaides–Baraitser syndrome.
There is currently no specific treatment available for either of these so-called progeroid syndromes. With this in mind, what is most important when making a differential diagnosis with them is based on the prognosis, which appears to be far better in acrogeria.
Cooks syndrome is a hereditary disorder which is characterized in the hands by bilateral nail hypoplasia on the thumb, index finger, and middle finger, absence of fingernails (anonychia) on the ring finger and little finger, lengthening of the thumbs, and bulbousness of the fingers. In the feet, it is characterized by absence of toenails and absence/hypoplasia of the distal phalanges. In the second study of this disorder, it was found that the intermediate phalanges, proximal phalanges, and metacarpals were unaffected.
The disorder was first described by Cooks "et al." in 1985 after being discovered in two generations of one family. It was proposed that the inheritance of the disorder is autosomal dominant. A second family, this with three affected generations, confirmed that the inheritance of the disorder is autosomal dominant. Although several genetic disorders exist which can cause anonychia and onychodystrophy, such disorders often cause other anomalies such as deafness, mental retardation, and defects of the hair, eyes, and teeth. Cooks syndrome is not known to cause any such anomalies.
In 1999, a pair of siblings was found with brachydactyly type B. Because the disorder primarily affected the nails and distal phalanges, the research group concluded that brachydactyly type B and Cooks syndrome are the same disorder. However, in 2007, a 2-year-old girl was found with symptoms consistent with both brachydactyly type B and Cooks syndrome. It was found that the two syndromes were distinct clinically, radiologically, and genetically.
Corneodermatosseous syndrome (also known as "CDO syndrome") is an autosomal dominant condition with onset in infancy, characterized by corneal dystrophy, photophobia, diffuse palmoplantar keratoderma, distal onycholysis, skeletal abnormalities, with brachydactyly, short stature, and medullary narrowing of digits.
ICF syndrome (or Immunodeficiency, Centromere instability and Facial anomalies syndrome) is a very rare autosomal recessive immune disorder.
Acrogeria is extremely rare, with only about 40 cases having been reported in the medical literature, since 1941.
Gordon syndrome (GS), or distal arthrogryposis type 3, is a rare, autosomal dominant disorder characterized by cleft palate and congenital contractures of the hands and feet.
It is characterized by variable reductions in serum immunoglobulin levels which cause most ICF patients to succumb to infectious diseases before adulthood. ICF syndrome patients exhibit facial anomalies which include hypertelorism, low-set ears, epicanthal folds and macroglossia.
Woodhouse–Sakati syndrome, also called hypogonadism, alopecia, diabetes mellitus, intellectual disability and extrapyramidal syndrome, is a rare autosomal recessive multisystem disorder which causes malformations throughout the body, and deficiencies affecting the endocrine system.
EEM syndrome (or Ectodermal dysplasia, Ectrodactyly and Macular dystrophy syndrome) is an autosomal recessive congenital malformation disorder affecting tissues associated with the ectoderm (skin, hair, nails, teeth), and also the hands, feet and eyes.
Stimmler syndrome is an autosomal recessive genetic disorder whose symptoms appear before birth or during infancy. In a study of two sisters born within a year of each other, both with Stimmler syndrome, it was found that high levels of alanine, pyruvate, and lactate were present in both the blood and urine. It was believed that the alanine was derived from the pyruvate.
Zimmermann–Laband syndrome (ZLS), also known as Laband–Zimmermann syndrome, and Laband's syndrome, is an extremely rare autosomal dominant congenital disorder.
