[Juvenile idiopathic arthritis and lyme disease: a case report]

Lyme disease is a systemic infection due to Borrelia burgdor-feri. Joint involvement in children, when primary phase is unknown, can be confounded with juvenile idiopathic arthri-tis. We report a case of a 16 years old girt. who developed at the age of 14 a bilateral and symetrical polyarthritis of big and small joints with fever and cutaneous eruption of trunk. No clinical improvement was seen under disease modified treatment. More biological investigations were performed. leading to the diagnosis of Lyme disease. Clinical recovery was obtained under adapted antibiotherapy, Hence Lyme serology must be performed when atypical polyarthritis appears in a child especially in an endemic region of borrelia. burdogferi

[ unusual cause of secondary scoliosis vertebral osteoblastoma]

We report the observation of a 22-year-old man suffering from nocturnal back pain for 2 years. The clinical examination shows a scoliosis. Imaging suggests either malignant tumor or an aggressive osteoblastoma of the sixth thoracic vertebra. After radical removal of the tumor, histopathologic examination confirms the diagnosis of osteoblastoma. Like any other neoplasma, osteoblastoma should be detected and removed early, before being responsible for non-reversing neurological complications
