  • Associated clinical features that have been described include clubbing of digits, with or without paronychial thickening; arthralgias; seborrheic dermatitis; mechanical ptosis of thickened eyelids; periodontal disease; and palmoplantar hyperhidrosis.[doi.org]
  • On examination, the patient had coarse facial features, thickened eyelids and partial blepharoptosis.[edmcasereports.com]
  • Ophthalmic examination revealed thickened eyelids with a clear vision. Because of the mechanical ptosis, he had a history of repeated eye infection as his upper eyelid would touch the skin of face and was under treatment for the same.[jiaomr.in]


  • Comprehensive diagnostic workup in search of secondary causes was launched. On laboratory examination, CBC exhibited mild anemia with hemoglobin of 12.2 g/dL, metabolic panel including liver enzymes were within normal range.[doi.org]
  • Thus, a comprehensive workup is required to rule out underlying conditions.[12] In the case of clubbing with periosteal proliferation, however, intrathoracic malignancies account for approximately 90 percent of cases.[11] Etiology.[jcadonline.com]


  • In combination with NSAIDs and colchicine, treatment with sulfasalazine was started in both cases, and methotrexate was added to the treatment regimen of the female patient at the end of the first year. The patients were found to be typical PHO.[ncbi.nlm.nih.gov]
  • RANKL is thought to increase bone resorption. [18] Bone formation and pain drug treatment [ edit ] Rheumatologic symptoms can be improved by treatment with bisphosphonates, such as pamidronate or risedronate.[en.wikipedia.org]

  • Pathophysiology of HOA remains largely obscure. Several theories have been proposed including autonomic dysfunction with sympathetic bias ( 8 ) and dysfunctional fibroblast proliferation ( 9 ).[doi.org]
  • The underlying pathophysiology appears to be an abnormality of prostglandin E2 but the details have yet to be elucidated. 6 patient organizations facilitate support for PDP patients. 4 of them are situated in Europe (Finland [1], France [2], Greece [3[en.wikipedia.org]
