AIM: To determine liver transplantation outcomes in Wilson's disease (WD) patients, focusing on neurological manifestations. METHODS: This retrospective study assessed data from 16 WD patients (nine males, 56%) who had liver transplants between 1991 and 2007. Survival, graft function, and neurological complications were assessed during a follow-up period of up to 15 years. In addition, each patient's medical record was reviewed in detail to find the type of Wilson's disease (hepatic or hepatic plus neurological WD), indication for liver transplantation, use of chelating agents prior to transplantation, immediate and long term complications following transplantation, the donor details, and the pathology of explanted liver. RESULTS: End-stage liver disease was the indication for transplantation in all 16 WD patients. Four patients displayed WD-related neurological symptoms in addition to liver disease. Living-related liver transplantation was done in three cases. One patient died on postoperative day 6 due to primary graft non-function. Oneyear post liver transplant survival was 94%. Neurological manifestations of all four patients disappeared during their follow-up. Four patients developed acute cellular rejection, but all responded to treatment. One patient developed chronic ductopenic rejection after 15 years post-transplantation and their graft failed; this patient is currently waiting for re-transplantation. Fourteen patients (88%) are still living. The long-term average survival is currently 10.5 years, with a current median survival of 8 years. Long-term graft survival is currently 81%. CONCLUSION: Shortand long-term survival in WD patient liver transplantation was excellent, and neurological and psychological WD manifestations disappeared during long-term follow-up.

Flexible energy storage devices are essential for emerging flexible electronics. The existing state-of-the-art Li-ion batteries are slowly reaching their limitation in terms of cost and energy density. Hence, flexible Na-ion batteries (SIBs) with abundanee Na resources and Li-S batteries with high energy density become the alternative for the Li-ion batteries in future. This review summarizes the recent advances in the development of flexible electrode materials for SIBs with metallic matrix and carb on aceous matrix such as carb on nano-tubes, carbon nano-fiber, graphene, carbon cloth, carbon fiber cloth, and cotton textiles. Then, the potential prototype flexible full SIBs are discussed. Further, the recent progress in the development of flexible electrode materials for Li-S batteries based on carb on nano-fiber, carb on nano-tubes, graphene, and cotton textiles is reviewed. Moreover, the design strategies of suitable interlayer, separator, electrolyte, and electrodes to prevent the dissolution and shuttle effect of polysulfides in flexible Li-S batteries are provided. Finally some prospective investigation trends towards future research of flexible SIBs and Li-S batteries are also proposed and discussed. The scientific and engineering knowledge gained on flexible SIBs and Li-S batteries provides conceivable development for practical application in near future.

Objective: To study epidemiological trends related to cutaneous leishmaniasis (CL) in al Hassa, an endemic area in Saudi Arabia. Methods: This retrospective study included the spatial/ temporal analysis of the reported cases of CL using the available surveillance database for the disease at the regional Vector Control Unit, from 2000 to 2010. Results: The incidence of CL was declining at a stable rate especially during the last 3 years of the study (2008-2010). An interesting finding was the percentage of expatriates affected was increasing over the last 10 years compared to that of the Saudis. Conclusions: A definite declining trend in the incidence of CL was observed in al Hassa. Further studies are warranted to assess whether special public health measures are needed for better control of CL in expatriate populations in Saudi Arabia.
