Visual Phenomenon

Background: We encountered a young female presenting with a complaint of “pixelated vision”. A brief literature search at the time of consultation showed no peer reviewed publications. Our objective was to use an infodemiologic approach to investigate the possible occurrence of an unidentified visual phenomenon.Methods: An Internet search with the metabrowser search engine Dogpile (www.dogpile.com) was conducted on April 24, 2018, using free text words “pixelated” and “vision.” The first 100 results were scanned for forum posts and cross-referenced to minimize duplication.Results: Of the first 100 results, 15 unique posts were identified. The majority of posts were made by the affected individual (n=14, 93%). Sex was female (n=5, 33%), male (n=2, 13%) or unknown (n=8, 53%). Onset was identified as new (n=10, 67%) or chronic (n=5, 33%).Conclusion: The availability and content of these forum postings suggest that pixelated vision is an uncommon, non-pathological visual phenomenon not yet documented in conventional medical literature.

Lower Back

Background: Myxopapillary ependymoma (MPE) with anaplastic features is extremely rare. There are very few such case reports in the medical literature. Case Description: A 23-year-old female presented with lower back pain, and both urinary and fecal dysfunction. The patient underwent gross total surgical excision of the MR documented expansile intrasacral tumor. The histology was compatible with a MPE containing anaplastic features. Conclusion: The medical literature contains a few comparable cases of subcutaneous sacrococcygeal MPE with anaplastic components. Here, however, we have a young female with an anaplastic intrasacral MPE treated with gross total surgical excision.

Empirical Regularities

Unique queries submitted to the Excite search engine were analyzed for empirical regularities in the co-occurrence of search terms. The distribution of frequency of term pair occurrences was fitted to three models used in informetric studies to determine whether the pattern of term usage followed a Zipfian distribution. Relatively poor fits were obtained for two of the models tested. . .

 Ectopic thyroid is the result of the failure of migration of thyroid along its tract from the floor of the primitive foregut to its final pretracheal position. The incidence of an ectopic lesion in adults is 7%. Most common location is the base of tongue (lingual). Other diverse sites are larynx, trachea, mediastinum, and pericardium. These ectopic tissues may develop the same diseases as the thyroid gland. Here, we report a case of a young female presenting with a foreign body sensation in the throat and on examination revealed a smooth submucosal swelling involving the supraglottis. The entire cyst was excised in toto by KTP 532 laser via an endolaryngeal approach and it was reported as papillary carcinoma of the thyroid. Literature search reported only a few cases of intralaryngeal ectopic thyroid and none with a papillary carcinoma of the larynx. This is the first reported case of papillary carcinoma of thyroid in the larynx.

Medicinal Cannabis

Objective: To investigate beliefs about treatment capabilities of medicinal cannabis (MC), the effect of recreational cannabis (RC) on mental health and online cannabis search trends. Method: Participants ( n = 117) completed an online survey, and search engine optimisation software was used to analyse internet search trends. Results: Half the participants perceived RC as harmful to mental health but were uncertain if it impairs treatment for depression or prevents anxiety. Participants believed MC can treat depression and/or anxiety. The Google keyword ‘CBD oil’ is most popular when seeking cannabis information and provides misinformation. Conclusion: Australians are exposed to misinformation about MC online, explaining why participants believed that MC could treat anxiety and/or depression and why there is a reduction in the belief that RC is harmful to mental health. Health authorities should incorporate search engine optimisation strategies to provide accurate information about cannabis.

The Web

Political knowledge is central to understanding citizens’ engagement with politics. Yet, as surveys are increasingly conducted online, participants’ ability to search the web may undermine the validity of factual knowledge measures. Recent research shows this search behavior is common, even when respondents are instructed otherwise. However, we know little about how outside search affects the validity of political knowledge measures. Using a series of experimental and observational studies, we provide consistent evidence that outside search degrades the validity of political knowledge measures. Our findings imply that researchers conducting online surveys need to take steps to discourage and diagnose search engine use.
