Parija SC. Announcing the launch of Tropical Parasitology. Trop Parasitol 2011;1:1
On behalf of the Editorial board of the Tropical Parasitology, it is an immense pleasure to welcome all our readers to the first issue of this journal. It is indeed gratifying to note that the first issue contains some very interesting articles on varied topics from different parts of the country and sheds light on many aspects of parasitic diseases prevalent in the tropics. We wish all our readers a happy journey of textual reading.
A very rare case of cerebral paragonimiasis from India is being reported in this issue. Paragonimiasis is classically a pulmonary disease of carnivores and humans. Most of the infections are associated with Paragonimus westermani, the others being Paragonimus kellicotti and Paragonimus mexicanus. It is one of the food-borne helminths, commonly the raw or undercooked crustaceans which are incriminated. , The metacercarial migration from the abdominal cavity usually terminates in the lungs. Very rarely, these larvae may migrate to ectopic sites like the brain. This may result in necrosis within the brain tissue, cerebral edema and even meningitis. The presenting features may depend on the site of involvement.  From the diagnostic point of view, it is important to remember that typical pulmonary symptoms may be absent in ectopic paragonimiasis. Radiological investigations such as a CT scan or an MRI can determine the location of the parasite but may not be able to determine the etiology. Immunodiagnostic tests have been used to diagnose both pulmonary as well as extra pulmonary lesions. Complement fixation test can be diagnostic in active cases but not after the death of the worms. Immunoblot assay, ELISA, for the same have been found to be very sensitive and specific for the detection of antibodies.  Parasite antigens can be detected by using monoclonal antibodies employing methods like the Dot ELISA.  Intradermal test may remain positive for many years after parasitological cure. Cerebral pargonimiasis can mimic any intracranial space-occupying illness, and therefore, should be kept as a differential diagnosis especially in areas where this disease is endemic. This is more applicable to the North-eastern states of India viz. Manipur, Assam, etc.
The success of any public health program is dependent more on the Project implementation, management, monitoring and evaluation of project activities than the volume of financial resource allocation. The article on the performance of the Enhanced Malaria Control Project (EMCP), published in the current issue, throws light on the inherent problems of human resource availability and logistics in such field-based programs and tries to analyze possible reasons for poor performance of EMCP in few states of India like Odisha.
Ethics in human research is a burning issue in science. Keeping this in mind, the journal has started a series on ethics. The first of the series-article stresses on the fact that only such research should be undertaken whose sole objective would be to advance the betterment of mankind. There are national and international guidelines available which give directions for conducting research.
This issue, in addition, contains reviews on the recent aspect of diagnosis of amebiasis by employing molecular techniques and also dwells into vaccine research regarding the same. The issue also deals with the enteric spore-forming parasites and other intestinal helminths like Strongyloides stercoralis which are problematic especially in the immunocompromised. The role of immunological methods as means of diagnosis in cysticercosis and echinococcosis has been projected in the issue.
I welcome any constructive criticism and suggestions/advice which will help in structuring the future issues of the Tropical Parasitology.
