Early Findings of Rickettsioses in Morocco.

BACKGROUND & OBJECTIVES: Rickettsioses are zoonoses transmitted to humans by arthropods. They are due to strict intracellular bacteria belonging to the family Rickettsiaceae. Our purpose is to present the clinical and paraclinical characteristics of 14 new cases diagnosed in Al-Hoceima region, Morocco; indeed, the patients associated a diagnosis of Mediterranean Spotted Fever (MSF). RESULTS: The average age of patients was 55 years. The patients were hospitalized for infectious syndrome, renal deficiency, pneumonia, and suspected meningitis. All cases had a general papular rash with palmo-plantar involvement, 12 out of 14 patients showed an escarotic spot, while neurological disorders were observed in 2 patients. Ophthalmic involvement was represented by retinal vasculitis in a single patient. Thrombocytopenia and cytolysis were constant in all patients. Renal deficiency was found in 3 cases and 2 cases had interstitial syndrome. The serology was positive in only one patient. All cases had been treated with doxycycline 200mg/day for 7 days with a good improvement of the clinical and biological symptoms. INTERPRETATION & CONCLUSION: The frequency of MSF in Morocco is not completely elucidated. A good knowledge of the clinical form allows an early diagnosis in order to institute an effective treatment.

Ankylosing spondylitis associated with Sweet's syndrome: a case report.

INTRODUCTION: Sweet's syndrome is an acute neutrophilic dermatosis characterized by a diffuse dermal infiltrate of mature neutrophils. In most cases, it occurs as an isolated phenomenon (idiopathic Sweet's syndrome) but it can be drug induced or associated with a variety of underlying diseases such as infections, neoplasms, and chronic inflammatory diseases. The association between Sweet's syndrome and ankylosing spondylitis is rare. Only a few cases have been reported in the literature. We report a new case in which we describe an outbreak of acute neutrophilic dermatosis revealing ankylosing spondylitis. CASE PRESENTATION: A 33-year-old Moroccan man presented with large-joint polyarthralgia, inflammatory pain in his buttocks and lower lumbar spine, fever and skin lesions. On examination, the patient had a low-grade fever, six tender but not swollen joints, limitation of motion of the lumbar spine, and painful erythematous maculopapules over his face, neck, and hands. Laboratory tests showed hyperleukocytosis, and elevated erythrocyte sedimentation rate and C-reactive protein. The immunological tests and infectious disease markers were negative. Investigations for an underlying neoplastic disease remained negative. Magnetic resonance imaging showed a bilateral sacroiliitis. Skin biopsy findings were consistent with Sweet's syndrome. The diagnosis of Sweet's syndrome associated with ankylosing spondylitis was established. Nonsteroid anti-inflammatory drugs were started and the patient showed rapid clinical and biological improvement. CONCLUSION: Three observations of the association between Sweet's syndrome and spondylarthropathy have been reported in the literature. The cause of this association remains unclear. Some hypotheses have been developed, but further studies are needed to confirm or refute them.
