Abstract
Cysticercosis is caused by Taenia solium, a cestode or tapeworm that preferentially affects the subcutaneous tissue, brain, muscle, and the eye. It is traditionally a disease of low socioeconomic regions, but large-scale population migration has made it a matter of global concern. Its ocular invasion is a potentially blinding disease. In the last two decades, there has been considerable discussion of cysticercosis; however, most comes from a limited number of case observations. Thus, to overcome this limitation, we summarize and analyse twenty years of medical literature (from 2000 to 2020) on cysticercosis in ophthalmology.

[PMID: 32276368 PMCID: PMC7180804 DOI: 10.3390/s20072092] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/26/2020] [Revised: 04/02/2020] [Accepted: 04/05/2020] [Indexed: 12/20/2022]
Abstract
A fiber optic array (FOA) can be used as an alternative or a supplement to the lens in a microscope due to its large magnification, high coupling efficiency and extremely low distortion. Based on our previous research, this paper first demonstrated the resolution and field-of-view (FOV) of the microscope based on the FOA. To further validate the FOA microscope’s imaging capability, yeast activity and concentration were investigated by simple image processing. The results showed that the percentages of live and dead yeast cells correctly identified were 92.1% and 84.8%, except for the clusters, which agreed well with the manual counting methods. Then, the performances of the portable microscopes based on the FOA and lens were compared and the factors that affect the FOA microscope imaging performance were analyzed.

Abstract
Accurate and rapid diagnosis is crucial in combating parasitic diseases that cause millions of deaths worldwide. However, the scarcity of specialized diagnostic equipment in low- and middle-income countries is one of the barriers to effective management of parasitic diseases and warrants the need for alternative, inexpensive, point-of-care diagnostic tools. Due to their multiple built-in sensors, smartphones offer cost-effective alternative to expensive diagnostic devices. However, the use of smartphones in parasitic diagnoses remains in its infancy. This minireview describes various smartphone-based devices applied specifically for the diagnosis of parasitic diseases and discusses challenges and potential implications for their use in future.

Abstract
The "Smartphone" is an almost universal possession in high-income populations, and is rapidly becoming so in lower-income regions, particularly among urban populations, and serves social networking and a quest for information and knowledge. The field of infectious disease diagnostics is at a potential watershed moment, with the essential building blocks for the development of diagnostic assays being ever more available and affordable, which is leading to creative innovative approaches to developing much-needed accurate and simple point-of-care (POC) diagnostic tools for high disease burden, low-income settings. We review the importance and implications of a paper published in Science Translational Medicine on the development of a smartphone-powered and -controlled multiplex immunological assay that tests for HIV and syphilis simultaneously. This is reviewed in the context of other prototype smartphone-enabled/assisted diagnostic devices, and how such developments might shape the future of the POC diagnostics field.
