The Myiases

Author(s):  
Mahmoud N. Abo-Shehada

Human myiases can be caused by over 50 species of dipteran larvae. The numbers of human clinical myiasis reports, reflect their relative importance in the following order; cutaneous, ophthalmomyiases, nasal, oral, intestinal, ear, urogenital, and cerebral myiases. Myiasis producing flies are distributed worldwide, but most reported cases are from warm and developing countries. Molecular techniques have been applied to myiasis fly identification and classification, especially ostrids and calliphorines. Successful elimination programs have been carried out against Hypoderma spp. in the UK and Cochliomyia hominivorax in the USA, Mexico, Central America, Libya and the Caribbean Islands and another is ongoing against Crysomya bezziana in the Middle East. A beneficial myissis “Biosurgery or maggot therapy” is the intentional use of Lucilia sericata larvae applied in specially designed dressings to chronic and MRSA infected wounds. The growing larvae execration/secretion facilitate wound debridement and successfully treated leg and pressure ulcers, wounds associated with diabetes, and many other types of infected wounds in a shorter time compared to conventional treatment. Now knowledge of myiases producing flies is accepted in many countries as a forensic tool.

Purpose – The purpose of this paper is to examine the indexing method used by Caribbean libraries to describe special collections and manuscripts. Design/methodology/approach – Various types of finding aids spanning 1960-2014 are used to show the pattern of descriptions adopted by the librarians. At the same time, the factors which have sustained the approach at national libraries and university libraries are highlighted. Findings – The paper concludes that while the indexing approach may be labour-intensive, this practice is perceived as developing a national and regional documentary heritage. The materials used for this study are primarily accessible to the public inclusive of published guides and online databases. Originality/value – The literature is replete with theories and cases from places such as the UK, the USA and Australia, this paper presents a perspective on the development of archival description in the Caribbean.

These comments, from Peter Hulme’s introduction, strike a keynote for this essay collection as a whole. Although some of its contributors align themselves with those very postmodern arguments from which Hulme marks his distance, they all share his concern with scaling down postcolonial cultural analysis and theorization to focus on particular cultural, historical, and geographical cases. This provides a striking contrast with the earlier stages of the “industry,” as inaugurated by Edward Said’s Orientalism (1978), which was concerned with mapping a phenomenon of massive historical and geographical proportions; or, alternatively, with Homi Bhabha’s projects in the mid-1980s (Location chap. 2-6), which took up the task of theorizing a generalized colonial subjectivity. It is not only the focus on “locality” which differentiates this collection from the earlier work of Said and Bhabha. This earlier stage of colonial dis-course/postcolonial theory privileged India and the Orient as objects of study (Said) or as the example from which psychoanalytic patterns could be derived (Bhabha). In this collection of twelve chapters, only one is devoted to India. The rest cover a striking regional range, including Spanish America, the Philippines, the Caribbean, West Africa, South Africa, France, the USA, and the UK. This diversity of regions ushers in a broadening of theoretical as well as physical terrain. Despite the volume’s title, “discourse” theory in a strongly Foucauldian sense is not prevalent in the contributions. And contrary to the title’s suggestion, colonialism serves more as an epistemological and political matrix than as a topic of analysis.

AbstractIn this article, the trends in human parasitology have been studied through the analysis of the number of publications in this area. The parameters studied were: number of articles, language, countries and institutions with the highest number of publications, and keywords with greater presence in the articles of human parasitology. The results of the analysis confirm the growing interest in this area, observing an exponential growth in the number of publications in the last decades. We also verified that the main country in terms of scientific production is the USA, although among the most important institutions, we find non-US centres such as the Oswaldo Cruz Foundation and the London School of Hygiene and Tropical Medicine. For observing the relative importance of the journals that publish articles in this specific topic, an index has been created based on theh-index of the journal with publications related to human parasitology and divided by every 100 items. This rank is led fist by ‘Journal of Medical Entomology’ closely followed by ‘Parasitology’. The analysis of the keywords allows to draw conclusions about the great importance of malaria in the current world research. A change in analytical methodology is also observed, and molecular techniques are now being imposed. These techniques, in the near future, have to influence in an improvement in the treatments and prevention of the diseases caused by parasites. Finally, it can be seen that diseases traditionally studied as helminthiasis and amebiasis are currently as well studied as others such as toxoplasmosis or leishmaniasis.

Sickle cell disease (SCD) is one of the commonest severe inherited disorders, but specific treatments are lacking and the pathophysiology remains unclear. Affected individuals account for well over 250,000 births yearly, mostly in the Tropics, the USA, and the Caribbean, also in Northern Europe as well. Incidence in the UK amounts to around 12–15,000 individuals and is increasing, with approximately 300 SCD babies born each year as well as with arrival of new immigrants. About two thirds of SCD patients are homozygous HbSS individuals. Patients heterozygous for HbS and HbC (HbSC) constitute about a third of SCD cases, making this the second most common form of SCD, with approximately 80,000 births per year worldwide. Disease in these patients shows differences from that in homozygous HbSS individuals. Their red blood cells (RBCs), containing approximately equal amounts of HbS and HbC, are also likely to show differences in properties which may contribute to disease outcome. Nevertheless, little is known about the behaviour of RBCs from HbSC heterozygotes. This paper reviews what is known about SCD in HbSC individuals and will compare the properties of their RBCs with those from homozygous HbSS patients. Important areas of similarity and potential differences will be emphasised.

It is now a universally acknowledged fact that maggot therapy can be used successfully to treat chronic, long-standing, infected wounds, which have previously failed to respond to conventional treatment. Such wounds are typically characterized by the presence of necrotic tissue, underlying infection and poor healing. Maggot therapy employs the use of freshly emerged, sterile larvae of the common green-bottle fly,Phaenicia(Lucilia)sericata, and is a form of artificially induced myiasis in a controlled clinical situation. In this review article, we will discuss the role of maggots and their preparation for clinical use. Maggot therapy has the following three core beneficial effects on a wound: debridement, disinfection and enhanced healing. In part I we explore our current understanding of the mechanisms underlying these effects.

The study introduces a Hungarian economic thinker, István Varga*, whose valuable activity has remained unexplored up to now. He became an economic thinker during the 1920s, in a country that had not long before become independent of Austria. The role played by Austria in the modern economic thinking of that time was a form of competition with the thought adhered to by the UK and the USA. Hungarian economists mainly interpreted and commented on German and Austrian theories, reasons for this being that, for example, the majority of Hungarian economists had studied at German and Austrian universities, while at Hungarian universities principally German and Austrian economic theories were taught. István Varga was familiar not only with contemporary German economics but with the new ideas of Anglo-Saxon economics as well — and he introduced these ideas into Hungarian economic thinking. He lived and worked in turbulent times, and historians have only been able to appreciate his activity in a limited manner. The work of this excellent economist has all but been forgotten, although he was of international stature. After a brief summary of Varga’s profile the study will demonstrate the lasting influence he has had in four areas — namely, business cycle research and national income estimations, the 1946 Hungarian stabilisation program, corporate profit, and consumption economics — and will go on to summarise his most important achievements.
