[Symptomatic periodic paralysis secondary to primary Sjogren's syndrome].

INTRODUCTION: Hypokalaemic periodic paralysis can be primitive or secondary to potassium deficiency which can arise from several causes. Primary Sjogren's syndrome is a rare cause related to kidney involvement. CASE REPORT: A 50-year-old woman has been admitted for hypotonic tetraparesis which had appeared a few days earlier. History taking revealed three previous similar episodes with a notion of oral and lacrimal dryness. Laboratory tests revealed severe hypokalaemia, hyperchloremia, alkaline urinary pH and a minima 24h proteinuria. Additional investigations led to the diagnosis of a primary Sjogren's syndrome defined on the basis of international criteria. Kidney biopsy revealed tubular-interstitial nephritis. Oral corticosteroïd therapy and potassium supplementation led to symptom improvement. A recurrent episode also responded to treatment. Additional urinary alkalinisation has prevented further relapse. DISCUSSION: Primary Sjogren's syndrome is an exocrine disease causing systemic disorders. Tubular-interstitial nephropathy may occur in 25 percent of patients leading to distal tubular acidosis defined by the association of hypokalaemia, hyperchloremia and alkaline urinary pH. When hypokalaemia is severe, periodic paralysis may occur. CONCLUSION: Primary Sjogren's syndrome can lead to nephropathy and subsequent hypokalaemic periodic paralysis. Urinary alkalinisation is essential to prevent this catastrophic presentation from recurring.

[Chronic inflammatory demyelinating polyradiculoneuropathy in childhood: outcomes after methylprednisolone pulse therapy].

INTRODUCTION: Chronic inflammatory demyelinating polyneuropathy (CIDP) in children is relatively rare and treatment is based primarily on intravenous immunoglobulins or oral corticosteroids. Boluses of methylprednisolone (MP) are a seldom used alternative. CASE REPORT: We report the case of an 8-year-old child, first presented at the age of 3 years, with recurring episodes of functional impotence of both lower limbs and walking impairment, partially reversible without treatment. Clinical, progressive, and electrophysiological data and the analysis of the cerebrospinal fluid were compatible with CIDP. MP boluses were administered: after a total eight monthly boluses, very satisfactory progression on the clinical and electrophysiological fronts was noted after 24 months. CONCLUSION: Childhood CIDP presents clinical, electrophysiological, progressive, and prognostic particularities, they recur readily and the outcome is good. Boluses of methylprednisolone are an alternative to the treatment of these neuropathies in childhood.

[Devic's neuromyelitis optica in Morocco. A study of 9-cases].

INTRODUCTION: Optic neuromyelitis or Devic's syndrome associates optic neuritis and myelitis. It can have a monophasic or relapsing course. The limits of this entity remain controversial. METHODS: We analyzed the results of a retrospective series of Moroccan patients with Devic's syndrome defined on the basis of Wingerchuk's criteria. RESULTS: Six women and three men were retained for study; average age was 39 years. Three patients presented with a monophasic form and six with relapsing disease. CSF analysis was abnormal in five. Brain MRI was normal in eight. Signal abnormalities extended over more than three vertebrae in eight patients. Infections were associated with neurological features in half of the patients. DISCUSSION: Our results are in agreement with those of large series in the literature regarding the clinical, imaging, and laboratory findings and disease course. We also noted that infections were more frequently associated with Devic's syndrome in our patients. CONCLUSION: Our study reports the results of the first North African series of Devic's syndrome patients. We suggest that this syndrome is particular in our context due to the high frequency and diversity of associated infections.

[Aseptic meningoencephalitis in primary Gougerot-Sjögren's syndrome].

INTRODUCTION: Central nervous system involvement is rarely observed in primary Sjogren's syndrome (PSS) and aseptic meningoencephalitis occurs exceptionally. OBSERVATION: We report the case of a 25-year-old woman who presented with weakness of the four limbs, vision loss and concentration deficit. Neurological examination revealed a mental confusion, cerebellar involvement and spastic tetra paresis. Cerebrospinal fluid analysis revealed elevation of cell counts (162/mm3) and protein content (3 g/l). MRI showed increased T2 signals in the white matter. No evidence for an infectious etiology, especially tuberculosis, was obtained in this patient. PSS was diagnosed on the basis of ocular dryness, lachrymal hyposecretion, aspects of labial gland biopsy witch revealed destruction of the ducts with periductal lymphocytic infiltration and positive anti-SSB antibodies. Oral corticosteroids (1 mg/kg/day) allowed an improvement of the neurological manifestations. CONCLUSION: Aseptic meningoencephalitis can be the first manifestation of primary Sjogren's syndrome. Infectious causes, particularly tuberculosis which is frequent in our context must be ruled out.

[Devic's optic neuromyelitis and pulmonary tuberculosis].

INTRODUCTION: Optic neuromyelitis or Devic's syndrome is a very rare disease affecting the optic tracts and the spinal cord. Its association with evolving pulmonary tuberculosis has been noted in a handful of case reports. CASE REPORT: The authors reportthe case of a 40 year old patient with evolving pulmonary tuberculosis who experienced bilateral blindness followed by paraplegia and sphincter disturbance. Clinical examination and investigations excluded direct tuberculous involvement of the nervous system or a reaction to antituberculous therapy and Devic's syndrome was diagnosed, based on Wingerchurk's criteria. Following treatment with corticosteroids and antituberculous chemotherapy, the patient recovered normal mobility and sphincter control but remained completely blind. CONCLUSIONS: Throughout this case report, the authors emphasise the rarity of this association and discuss the pathophysiological mechanism, which appears to be an immune dysfunction triggered by mycobacterial infection.
