Guillain-Barré Syndrome outbreak associated with Zika virus infection in French Polynesia: a case-control study.

Background: Between October, 2013, and April, 2014, French Polynesia experienced the largest Zika virus outbreak ever described at that time. During the same period, an increase in Guillain-Barré syndrome was reported, suggesting a possible association between Zika virus and Guillain-Barré syndrome. We aimed to assess the role of Zika virus and dengue virus infection in developing Guillain-Barré syndrome.

[Transient global amnesia: A descriptive study of 12 Polynesian patients].

Introduction: According to the criteria of Hodges and Warlow, transient global amnesia is defined by sudden onset of isolated anterograde amnesia of spontaneous resolution within one to twenty-four hours. Its pathophysiological mechanisms are still uncertain.

Methods: In a retrospective study, we have analyzed epidemiological, clinical and MRI data from twelve patients admitted to the only neurological department of French Polynesia for transient global amnesia corresponding to the criteria of Hodges and Warlow between January 2010 and December 2013.

[Polynesian adaptation of the Mini-Mental State Examination].

This study aimed to develop and validate a Polynesian version of the MMSE (Mini-Mental State Examination). For this study a sample (n=112) of healthy people were evaluated with the French version of the consensual version of the MMSE, to target and modify some inadequate items for French Polynesia. Subsequently, a second sample (n=112) with the same characteristics (age, educational level) as well as 46 healthy people aged 60 years and more were evaluated with the adaptive version of the MMSE (P-MMSE).

[Single procedure treatment of complex nephrolithiasis: about a modern series of anatrophic nephrolithotomy].

Purpose: Advances in endourology have significantly reduced indications of open surgery in the treatment of staghorn calculi. However, in our experience, open surgery is still the treatment of choice in some cases. This study presents the results of a series of selected patients and discusses the results in terms of efficacy and morbidity.

[Ciguatera fish poisoning].

Ciguatera, an ichtyosarcotoxism linked to the consumption of usually healthy coral fish is a common poisoning in the Pacific, Caribbean and Indian Ocean where it is endemic. However, increased tourism and commercial transportation of tropical fish for consumption make it an unexceptional intoxication in countries away from its endemic area. Environmental stresses such as climate changes also contribute to the expansion of its geographical area.

[Myopericarditis as the presenting manifestation of adult Still's disease].

Introduction: Adult Still's disease may present with multiple non-specific clinical manifestations leading to diagnostic difficulties. Presentation as initial myopericarditis is rare but must be known.

Case Report: We report a 49-year-old man who presented with the sudden onset of a high fever, arthralgia and myalgia, skin rash, dyspnea and chest pain related to a myopericarditis.

[Eosinophilic meningitis].

Introduction: Diagnosis of Angiostrongylus cantonensis meningitis is not always obvious, even in endemic areas.

Case Report: We report a 51-year-old Polynesian man, farmer without past medical history, who was admitted for mild fever, headache, neurological subjective symptoms, and severe muscle pain impeding walking. The diagnosis of A.

[Macrophage activation syndrome as the presenting manifestation of intravascular lymphoma].

Introduction: Intravascular large B cell lymphoma is a neoplastic cell proliferation leading to the occlusion of the lumen of small vessels. This is a rare haematological malignancy, which is difficult to diagnose because of a heterogeneous clinical presentation.

Case Report: We report a 62-year-old man who presented a macrophage activation syndrome as the presenting manifestation of an intravascular lymphoma.

[Infectious complications rate from hemodialysis catheters: experience from the French Polynesia].

The arterio-venous fistula (AVF) is the most common vascular access to perform hemodialysis (HD). The HD venous central catheter use should only be proposed to old patients and/or patients without vascular access construction feasibility. These HD catheters are often responsible of infectious and thrombosis complications.

[Neurological manifestations of dengue].

Background: An epidemic of type 4 dengue was raging in the Pacific from 2008 to 2010. During this period, several patients were hospitalized at the Hospital Centre of Tahiti for neurological disorders occurring during a dengue fever. These events are not the typical picture, which is represented by a flu-like syndrome and sometimes, in severe cases, a haemorrhagic syndrome or shock.

[Hemophagocytic lymphohistiocytosis and Epstein-Barr virus infection in children].

Objective: The authors had for aim to review pediatric cases of EBV-associated hemophagocytic lymphohistiocytosis observed, between January 1999 and December 2007, to compare their characteristics to literature data, and to suggest a pragmatic strategy for diagnosis and treatment.

Design: The following were analyzed for each patient: age at diagnosis, family history, revised Henter diagnostic criteria, EBV serology and/or PCR, results of genetic studies when available, treatment, short and long-term outcome.

Results: Four patients 11 months to seven years of age were admitted for high and prolonged fever, hepato and/or splenomegaly, and biological markers of hemophagocytic lymphohistiocytosis.

[Ciguatera and acute polyradiculoneuritis. Description of two cases in French Polynesia: immunoallergic hypothesis?].

Ciguatera is a foodborne poisoning caused by eating seafood from tropical and subtropical reef areas. According to official data from the local health department, cases of ciguatera in French Polynesia are estimated to involve 240 to 400 persons per 100 000 inhabitants. Associated with a wide spectrum of gastrointestinal, cardiovascular, nervous, and general signs, ciguatera is usually benign although some forms can lead to hospitalization.
