Orthotic management with a customized humeral brace for Gorham-Stout disease of the humerus: A case report

@#Gorham-Stout disease is characterized by massive osteolysis or "vanishing bone" on radiograph. Due to its rarity, no standard Physical Medicine and Rehabilitation (PM&R) management has been published. With this comes the dilemma of managing another case of vanishing right humerus in a 13 year-old male, right handed student, with normal growth and development. To date, this could be the third documented case in the Philippines, but the first with humeral involvement, and the first to manage using a customized humeral brace. The absence of the right humerus affects the bimanual overhead and tabletop activities of the patient, for which a custom-made humeral orthosis was provided to manage the limited activities. There were improvements in activities such as writing, card turning, stacking, and lifting objects of variable weights, as well as with hand dexterity as evidenced by the standardized hand function tests done prior and post brace fitting. Being a rare bone disease with no standard management and unpredictable course, cases are managed symptomatically. For this case of an absent humerus significantly affecting upper extremity function, orthotic management is one aspect that could be recommended to achieve positive functional outcomes.

Osteólisis multicéntrica no hereditaria con nefropatía: reporte de un caso y revisión de la literatura / No hereditary multicentric osteolysis with nephropathy: report of a case and review of the literature

La osteólisis idiopática multicéntrica (OIM) se caracteriza por el compromiso de carpos y de tarsos, con inflamación y dolor; se inicia en la infancia y se autolimita en la 2a o 3a década de la vida. Según Hardegger, se describen tipos hereditarios dominantes (tipo I) o recesivos asociados a osteoporosis (tipo II), OIM esporádicas con compromiso renal (tipo III) u osteólisis masiva monocéntrica (tipo IV). El tipo V se caracteriza por clínica similar al tipo II asociada a lesiones oculares o dermatológicas y talla baja. En esta oportunidad se presenta el caso clínico de una OIM tipo III. Consulta un varón de 50 años con antecedentes de dolor, tumefacción y deformidad en ambos carpos y tarsos y compromiso funcional de inicio en la infancia. A los 34 años presenta proteinuria, edemas e hipertensión arterial, desarrolla insuficiencia renal crónica (ICR). Se realizó trasplante renal. Sin antecedentes familiares de OIM. Se comprueba: disminución en la función de ambas manos, limitación en la extensión de muñeca y deformidad en los dedos, y distrofia muscular de antebrazos y piernas. Camina con dificultad. En las radiografías se observa ausencia de huesos del carpo y tarso, osteólisis en algunas falanges. Se indica tratamiento con bifosfonatos, vitamina D y rehabilitación. El paciente presenta OIM asociada a IRC e hipertensión arterial. Por carecer de antecedentes familiares se la considera OIM del tipo III. La OIM es una enfermedad infrecuente; el diagnóstico oportuno evita tratamientos innecesarios y permite tratar la enfermedad renal y la hipertensión en estadios más tempranos.

Idiopathic Multicentric Osteolysis (IMO) is a rare disease characterizedby osteolysis of carpus and tarsus, with inflammation and painwith onset in childhood and arrest y the second or third decade. It isclassified by Hardegger in 5 Types, 1: Hereditary IMO with dominanttransmission. 2: Hereditary IMO with recessive transmission. 3: NonHereditary IMO, associated with nephropathy and hypertension. 4:Gorham´s Syndrome: massive osteolysis and replacement of bone bylymphatic or blood vessel tissue. 5: Winchester Syndrome: IMO withshort stature, contractures, thick skin, corneal opacities and osteoporosis.A 50 year old male with a history of pain, swelling and deformityin both wrists and tarsi evolving from age 4, attends the consultation.He has functional involvement of hands and feet. At age 34, he hadreferred the presence of proteinuria, edema and hypertension, anddeveloped chronic renal falilure (CRF). Dialysis and renal transplantationwere indicated. No family history of IMO. Findings: Reducedfunction of boths hands, limited range of wrist and finger deformity,muscular forearms and legs dystrophy. He walked with difficulty. It isobserved on radiographs, absence of carpal and tarsal bones, phalangescommitment. Physiotherapy rehabilitation and treatment withbisphosphonates and vitamin D was indicated. A patient with IMO associatedwith CRF and hypertension was presented. He has absenceof family history. It is considered Type III IMO. The IMO is a rare diseases,early diagnosis prevents unnecessary treatment and can treatkidney disease and hypertension at an earlier stage.

Osteólisis multicéntrica idiopática de tipo III: presentación de un caso clínico y caracterización del síndrome / Idiopathic multicentric osteolysis type III: case report and syndrome characterization

Presentamos el primer reporte de caso en Colombia de un paciente con osteólisis multicéntrica idiopática con compromiso de carpo y tarso y nefropatía. Se exponen, de manera clara y bien documentada, el cuadro clínico y paraclínico actual y la evolución del paciente, junto a una breve y completa revisión de esta enfermedad, rara, progresiva, degenerativa e incapacitante.

We report the first case in Colombia of a patient with idiopathic multicentric osteolysis with carpal-tarsal compromise and nephropathy, The current clinical and paraclinical status of the patient is clearly exposed and well documented, along with a brief and comprehensive review of this rare progressive, degenerative and disabling disease.
