Methylation of SOCS3 in Myeloproliferative Neoplasms and Secondary Erythrocytosis/Thrombocythemia.

Objective: Myeloproliferative neoplasms (MPNs) like essential thrombocythemia (ET), polycythemia vera (PV), and primary myelofibrosis (PMF) are acquired clonal hematopoietic stem cell disorders and originate from a multipotent hematopoietic stem cell. The SOCS1 and SOCS3 genes are negative regulators of the JAK/STAT signal pathway. In this study we investigate the promoter methylation of these genes in the pathogenesis of MPNs and secondary erythrocytosis/thrombocythemia.

The presence of MEFV gene mutations in patients with primary osteoarthritis who require surgery.

Background/aims: Chronic arthritis of familial Mediterranean fever (FMF) involves weight-bearing joints and can occur in patients without a history of acute attack. Our aim was to investigate a possible causal relationship between FMF and osteoarthritis in a population in which FMF is quite common.

Methods: Patients with late stage primary osteoarthritis were enrolled, and five MEFV gene mutations were investigated.

Gorlin-Chaudhry-Moss syndrome revisited: expanding the phenotype.

Gorlin-Chaudhry-Moss syndrome (OMIM 233500) is a rare congenital malformation syndrome with the cardinal manifestations of craniofacial dysostosis, hypertrichosis, underdeveloped genitalia, ocular, and dental anomalies. Since 1960, only six affected individuals have been reported. We report a 4-year and 6-month-old female patient with this phenotype and review the clinical presentation of all patients known so far.

A case with oto-spondylo-mega-epiphyseal-dysplasia (OSMED): the clinical recognition and differential diagnosis.

The oto-spondylo-mega-epiphyseal-dysplasia (OSMED) phenotype is an autosomal recessive trait that is a skeletal dysplasia with the hallmark findings of limb shortening, multiple skeletal and radiological abnormalities, mid-face hypoplasia with a flat nasal bridge, small upturned nasal tip, and sensorineural hearing loss. A 3.5-year-old girl born to consanguineous Turkish parents had characteristic facial features at birth: mid-face hypoplasia, mild hypertelorism, upslanting palpebral fissures, prominent supraorbital ridges, depressed nasal bridge, small upturned nasal tip, long philtrum, and micrognathia.

New phenotype with generalized platyspondyly, large mandible, hypoplastic teeth, strabismus, hyperopia and low cholesterol levels.

A sporadic, adult male patient with generalized platyspondyly, large mandible, hypoplastic teeth, strabismus, and low serum cholesterol levels is presented. Some of the patient's features resemble brachyolmia, Spondylo-epiphyseal dysplasia tarda, Kenny-Caffey and Stickler syndromes. Based on literature review, possible diagnoses are discussed.
