“…However, the natural host of H. perplexum remains unknown. It has been identified in 12 human patients, who have contracted infection in Australia (Northern Australia and Tasmania) since 1998 (Dennett et al , 1998; Spratt, 2005; Basuroy et al , 2008; McKelvie et al , 2013; Vos et al , 2016; Koehler et al , 2018; Pritt et al , 2022; Ward et al , 2022). Clinical features common to infection are limb wasting and weakness associated with myositis, dysphagia and persistent eosinophilia, suggesting a long period of subclinical infection (Basuroy et al , 2008; Ward et al , 2022).…”

“…Clinical features common to infection are limb wasting and weakness associated with myositis, dysphagia and persistent eosinophilia, suggesting a long period of subclinical infection (Basuroy et al , 2008; Ward et al , 2022). Diagnosis based on symptoms alone is difficult given that they are similar to those of muscular dystrophy and inflammatory myopathy (Pritt et al , 2022). The source of infection with H. perplexum is not known and its zoonotic potential remains to be proven, although some of the cases were associated with the consumption of bush meat (Spratt, 2005; Ward et al , 2022).…”

Helminth zoonoses remain a global problem to public health and the economy of many countries. Polymerase chain reaction-based techniques and sequencing have resolved many taxonomic issues and are now essential to understanding the epidemiology of helminth zoonotic infections and the ecology of the causative agents. This is clearly demonstrated from research on Echinococcus (echinococcosis) and Trichinella (trichinosis). Unfortunately, a variety of anthropogenic factors are worsening the problems caused by helminth zoonoses. These include cultural factors, urbanization and climate change. Wildlife plays an increasingly important role in the maintenance of many helminth zoonoses making surveillance and control increasingly difficult. The emergence or re-emergence of helminth zoonoses such as Ancylostoma ceylanicum, Toxocara, Dracunculus and Thelazia exacerbate an already discouraging scenario compounding the control of a group of long neglected diseases.

“…Previous reports of human infections within Australia by nematodes within muscle tissues were initially diagnosed as T. pseudospiralis [30]. However, this has been shown to be a misidentification, with Haycocknema perplexum the actual parasite [37]. This parasite has only been reported from Australia (either in northern Queensland or Tasmania) with 13 known cases, all with an unknown source of infection [37].…”

Purpose of Review Consumption of wild game meat is traditionally associated with rural, remote and poor areas around the world, but there has been a recent rise in the consumption of wild game meat in urban and higher socio-economic regions such as Australia. Along with its unique animal fauna, Australia has a wide diversity of feral animals, many of which are hunted for food, although little is known about the levels of consumption of this meat across Australia. Corresponding with this is the lack of information on the parasites within these animals, particularly those of potential zoonotic concern through the consumption of raw or undercooked meat and organs. This review aimed to determine the level of knowledge of parasites of feral animals regularly consumed in Australia. Recent Findings Online databases were searched for publications on feral animals and their parasites. For the purpose of this review, only protozoal and helminth parasites that infest the muscle and organ systems and are infective to humans upon ingestion were considered as potential zoonotic parasites. A total of 5 records were found based on host and 27 based on parasite, showing a lack of information available. Summary Little information was available on the parasites of the major groups of feral animals hunted in Australia for food (pigs, deer, rabbits and hares, and goats) as well as on the parasites themselves, except for sparganosis caused by the cestode Spirometra erinaceieuropaei which has been widely reported in feral pigs. Sparganosis appears to be an underreported disease in Australia, with only 8 confirmed cases, highlighting the need for education of medical practitioners, especially in rural and remote areas, on the diagnosis of this infection.

Medical conditions associated with concurrent dysphagia and dysphonia

Swallowing - Problems and Management [Working Title]

View full text Add to dashboard Cite

Swallowing and voice production are important processes enabling a comfortable life. For appropriate alimentation, effective passage of food and fluids through a digestive system is necessary. Interpersonal communication depends on good voice and speech. Conditions associated with swallowing and speech problems leads dysfunctions and seriously affect the patient’s comfort of living. This chapter is a review of medical conditions associated with concurrence of dysphonia and dysphagia. There are a large number of medical conditions leading to the simultaneous occurrence of swallowing problems and hoarseness. The diversity of disorders is a serious interdisciplinary issue. Diagnostics of concurrent dysphagia and dysphonia is complicated and requires a holistic interdisciplinary approach. The reasons include functional and organic dysfunctions, neurological conditions, tumors, vascular disorders, autoimmune inflammations, post-operative complications, post-COVID complications, and others. Our research was conducted by reviewing PubMed and Scopus network using key words “dysphagia”, “dysphonia”, “hoarseness.” We found 966 publications, then narrowed the search to 99 articles describing medical conditions and case reports, which present with dysphagia and dysphonia occurring together. Detailed analysis enabled us to categorize the disorders into groups, depending on characteristics and body region involved in the pathological process. Finally, the description of the medical conditions was done systematically according to those groups.
