Trichorhinophalangeal syndrome: a case report and brief literature review.

Trichorhinophalangeal syndrome is an autosomal dominant disease caused by mutations in TRPS gene, characterized by skeletal, skin appendage, and endocrinological manifestations. Clinical presentation may vary widely, and the syndrome frequently remains undiagnosed. The diagnosis is mainly clinical, supported by radiographic images, and is confirmed by genetic investigation. Familiarity with this genetic disorder is crucial for providing correct and early identification, and for determining adequate supportive management, especially to prevent orthopedic complications.

Trichorhinophalangeal syndrome as a diagnostic and therapeutic challenge for paediatric endocrinologists.

Trichorhinophalangeal syndrome (TRPS) is rare genetic disorder with autosomal dominant inheritance. The TRPS1 gene is located on the long arm of the eighth chromosome (8q24.12). The phenotype is variable and presents a wide clinical spectrum. Most cases are characterised by thin, sparse scalp hair, distinctive facial dysmorphism, and various skeletal abnormalities, especially of the hands and feet. Characteristic facial features may include a "pear-shaped" nose, micrognathia, dental anomalies, prominent ears, elongated philtrum, and thin upper vermillion border. In most cases, affected individuals exhibit skeletal abnormalities including brachydactyly and clinodac-tyly, short metacarpals phalanges, short feet and metatarsals, and pectus carinatum and hip joint malformations. Additionally, patients may exhibit short stature. This report presents four cases of TRPS (three sporadic and one familial). Clinical presentation included typical facial features and vari-ous skeletal abnormalities. Some TRPS symptoms may mimic growth hormone deficiency and other endocrine disturbances. The aim of this article is to deliver TRPS symptomatology. The treatment of TRPS is symptomatic and supportive and requires the coordination of several specialists, including paediatricians, endocrinologists, orthopaedic surgeons, dermatologists, and medical rehabilitation and den-tal specialists. In some cases, recombinant growth hormone therapy may be necessary. Genetic counselling may be of benefit for affect-ed individuals and their families.

Rare monogenetic syndromes in rheumatology practice.

The EULAR Executive Committee defined eight overall objectives for EULAR to achieve by 2012. The first of these objectives is to strengthen activities in areas that are currently less prioritized, such as non-inflammatory and orphan diseases. This study aims to increase awareness of rheumatologists towards rare hereditary musculoskeletal disorders, by describing their genetics, pathogenesis, and typical clinical and radiological features. We analyzed patient charts from the recent 5 years from the Rheumatology Outpatient Department of the University Erlangen-Nuremberg and of two rheumatologic practices, all joined in a regional network ("Rheumazentrum Erlangen") retrospectively for hereditary musculoskeletal disorders other than hemochromatosis, autoinflammatory syndromes, lysosomal storage diseases, and hypermobility syndromes. We were able to identify four patients with trichorhinophalangeal syndrome type I, multiple exostoses, Kirner's deformity, and osteopoikilosis. In addition, a PubMed and OMIM ("Online Mendelian Inheritance in Man") database search was carried out using these as key words and all relevant articles were reviewed for each of these diseases. Our findings show that rare hereditary musculoskeletal disorders occur in a routine rheumatological setting and that rheumatologists should know the clinical and radiological features of these diseases in order to adequately counsel the patient.

Trichorhinophalangeal syndrome type II: case report.

Patients with the trichorhinophalangeal syndrome type II, also known as the Langer-Giedion syndrome, may present to the health care-givers or physicians in various specialties and need to be recognised in order that accurate diagnosis, management and counselling about prognosis and recurrence risks may be carried out. A case of young male with this condition is presented.
