"Journal of Clinical and Diagnostic Research is at present a well-known Indian originated scientific journal which started with a humble beginning. I have been associated with this journal since many years. I appreciate the Editor, Dr. Hemant Jain, for his constant effort in bringing up this journal to the present status right from the scratch. The journal is multidisciplinary. It encourages in publishing the scientific articles from postgraduates and also the beginners who start their career. At the same time the journal also caters for the high quality articles from specialty and super-specialty researchers. Hence it provides a platform for the scientist and researchers to publish. The other aspect of it is, the readers get the information regarding the most recent developments in science which can be used for teaching, research, treating patients and to some extent take preventive measures against certain diseases. The journal is contributing immensely to the society at national and international level."

" Journal of Clinical and Diagnostic Research (JCDR) is a multi-specialty medical and dental journal publishing high quality research articles in almost all branches of medicine. The quality of printing of figures and tables is excellent and comparable to any International journal. An added advantage is nominal publication charges and monthly issue of the journal and more chances of an article being accepted for publication. Moreover being a multi-specialty journal an article concerning a particular specialty has a wider reach of readers of other related specialties also. As an author and reviewer for several years I find this Journal most suitable and highly recommend this Journal."

Dr. Mamta Gupta,
"It gives me great pleasure to be associated with JCDR, since last 2-3 years. Since then I have authored, co-authored and reviewed about 25 articles in JCDR. I thank JCDR for giving me an opportunity to improve my own skills as an author and a reviewer.
It 's a multispecialty journal, publishing high quality articles. It gives a platform to the authors to publish their research work which can be available for everyone across the globe to read. The best thing about JCDR is that the full articles of all medical specialties are available as pdf/html for reading free of cost or without institutional subscription, which is not there for other journals. For those who have problem in writing manuscript or do statistical work, JCDR comes for their rescue.
The journal has a monthly publication and the articles are published quite fast. In time compared to other journals. The on-line first publication is also a great advantage and facility to review one's own articles before going to print. The response to any query and permission if required, is quite fast; this is quite commendable. I have a very good experience about seeking quick permission for quoting a photograph (Fig.) from a JCDR article for my chapter authored in an E book. I never thought it would be so easy. No hassles.
Reviewing articles is no less a pain staking process and requires in depth perception, knowledge about the topic for review. It requires time and concentration, yet I enjoy doing it. The JCDR website especially for the reviewers is quite user friendly. My suggestions for improving the journal is, more strict review process, so that only high quality articles are published. I find a a good number of articles in Obst. Gynae, hence, a new journal for this specialty titled JCDR-OG can be started. May be a bimonthly or quarterly publication to begin with. Only selected articles should find a place in it.
An yearly reward for the best article authored can also incentivize the authors. Though the process of finding the best article will be not be very easy. I do not know how reviewing process can be improved. If an article is being reviewed by two reviewers, then opinion of one can be communicated to the other or the final opinion of the editor can be communicated to the reviewer if requested for. This will help one’s reviewing skills.
My best wishes to Dr. Hemant Jain and all the editorial staff of JCDR for their untiring efforts to bring out this journal. I strongly recommend medical fraternity to publish their valuable research work in this esteemed journal, JCDR".

Dr. Rajendra Kumar Ghritlaharey

"I wish to thank Dr. Hemant Jain, Editor-in-Chief Journal of Clinical and Diagnostic Research (JCDR), for asking me to write up few words.
Writing is the representation of language in a textual medium i e; into the words and sentences on paper. Quality medical manuscript writing in particular, demands not only a high-quality research, but also requires accurate and concise communication of findings and conclusions, with adherence to particular journal guidelines. In medical field whether working in teaching, private, or in corporate institution, everyone wants to excel in his / her own field and get recognised by making manuscripts publication.


Authors are the souls of any journal, and deserve much respect. To publish a journal manuscripts are needed from authors. Authors have a great responsibility for producing facts of their work in terms of number and results truthfully and an individual honesty is expected from authors in this regards. Both ways its true "No authors-No manuscripts-No journals" and "No journals–No manuscripts–No authors". Reviewing a manuscript is also a very responsible and important task of any peer-reviewed journal and to be taken seriously. It needs knowledge on the subject, sincerity, honesty and determination. Although the process of reviewing a manuscript is a time consuming task butit is expected to give one's best remarks within the time frame of the journal.
Salient features of the JCDR: It is a biomedical, multidisciplinary (including all medical and dental specialities), e-journal, with wide scope and extensive author support. At the same time, a free text of manuscript is available in HTML and PDF format. There is fast growing authorship and readership with JCDR as this can be judged by the number of articles published in it i e; in Feb 2007 of its first issue, it contained 5 articles only, and now in its recent volume published in April 2011, it contained 67 manuscripts. This e-journal is fulfilling the commitments and objectives sincerely, (as stated by Editor-in-chief in his preface to first edition) i e; to encourage physicians through the internet, especially from the developing countries who witness a spectrum of disease and acquire a wealth of knowledge to publish their experiences to benefit the medical community in patients care. I also feel that many of us have work of substance, newer ideas, adequate clinical materials but poor in medical writing and hesitation to submit the work and need help. JCDR provides authors help in this regards.
Timely publication of journal: Publication of manuscripts and bringing out the issue in time is one of the positive aspects of JCDR and is possible with strong support team in terms of peer reviewers, proof reading, language check, computer operators, etc. This is one of the great reasons for authors to submit their work with JCDR. Another best part of JCDR is "Online first Publications" facilities available for the authors. This facility not only provides the prompt publications of the manuscripts but at the same time also early availability of the manuscripts for the readers.
Indexation and online availability: Indexation transforms the journal in some sense from its local ownership to the worldwide professional community and to the public.JCDR is indexed with Embase & EMbiology, Google Scholar, Index Copernicus, Chemical Abstracts Service, Journal seek Database, Indian Science Abstracts, to name few of them. Manuscriptspublished in JCDR are available on major search engines ie; google, yahoo, msn.
In the era of fast growing newer technologies, and in computer and internet friendly environment the manuscripts preparation, submission, review, revision, etc and all can be done and checked with a click from all corer of the world, at any time. Of course there is always a scope for improvement in every field and none is perfect. To progress, one needs to identify the areas of one's weakness and to strengthen them.
It is well said that "happy beginning is half done" and it fits perfectly with JCDR. It has grown considerably and I feel it has already grown up from its infancy to adolescence, achieving the status of standard online e-journal form Indian continent since its inception in Feb 2007. This had been made possible due to the efforts and the hard work put in it. The way the JCDR is improving with every new volume, with good quality original manuscripts, makes it a quality journal for readers. I must thank and congratulate Dr Hemant Jain, Editor-in-Chief JCDR and his team for their sincere efforts, dedication, and determination for making JCDR a fast growing journal.
Every one of us: authors, reviewers, editors, and publisher are responsible for enhancing the stature of the journal. I wish for a great success for JCDR."

Dr. Shankar P.R.

"On looking back through my Gmail archives after being requested by the journal to write a short editorial about my experiences of publishing with the Journal of Clinical and Diagnostic Research (JCDR), I came across an e-mail from Dr. Hemant Jain, Editor, in March 2007, which introduced the new electronic journal. The main features of the journal which were outlined in the e-mail were extensive author support, cash rewards, the peer review process, and other salient features of the journal.
Over a span of over four years, we (I and my colleagues) have published around 25 articles in the journal. In this editorial, I plan to briefly discuss my experiences of publishing with JCDR and the strengths of the journal and to finally address the areas for improvement.
My experiences of publishing with JCDR: Overall, my experiences of publishing withJCDR have been positive. The best point about the journal is that it responds to queries from the author. This may seem to be simple and not too much to ask for, but unfortunately, many journals in the subcontinent and from many developing countries do not respond or they respond with a long delay to the queries from the authors 1. The reasons could be many, including lack of optimal secretarial and other support. Another problem with many journals is the slowness of the review process. Editorial processing and peer review can take anywhere between a year to two years with some journals. Also, some journals do not keep the contributors informed about the progress of the review process. Due to the long review process, the articles can lose their relevance and topicality. A major benefit with JCDR is the timeliness and promptness of its response. In Dr Jain's e-mail which was sent to me in 2007, before the introduction of the Pre-publishing system, he had stated that he had received my submission and that he would get back to me within seven days and he did!
Most of the manuscripts are published within 3 to 4 months of their submission if they are found to be suitable after the review process. JCDR is published bimonthly and the accepted articles were usually published in the next issue. Recently, due to the increased volume of the submissions, the review process has become slower and it ?? Section can take from 4 to 6 months for the articles to be reviewed. The journal has an extensive author support system and it has recently introduced a paid expedited review process. The journal also mentions the average time for processing the manuscript under different submission systems - regular submission and expedited review.
Strengths of the journal: The journal has an online first facility in which the accepted manuscripts may be published on the website before being included in a regular issue of the journal. This cuts down the time between their acceptance and the publication. The journal is indexed in many databases, though not in PubMed. The editorial board should now take steps to index the journal in PubMed. The journal has a system of notifying readers through e-mail when a new issue is released. Also, the articles are available in both the HTML and the PDF formats. I especially like the new and colorful page format of the journal. Also, the access statistics of the articles are available. The prepublication and the manuscript tracking system are also helpful for the authors.
Areas for improvement: In certain cases, I felt that the peer review process of the manuscripts was not up to international standards and that it should be strengthened. Also, the number of manuscripts in an issue is high and it may be difficult for readers to go through all of them. The journal can consider tightening of the peer review process and increasing the quality standards for the acceptance of the manuscripts. I faced occasional problems with the online manuscript submission (Pre-publishing) system, which have to be addressed.
Overall, the publishing process with JCDR has been smooth, quick and relatively hassle free and I can recommend other authors to consider the journal as an outlet for their work."

Abstract

Honey is used as a common breakfast item all over the world. Honey is also used in cooking and baking, is used as a spread on breads and is added to beverages such as tea, or as a sweetener in commercial beverages.
In Nepal, there is a fancy for the use of wild honey. Honey is also used in weight reduction. Studies reported elsewhere pinpoint that wild honey is poisonous. This poisoning is well known from ancient times, right from the time of Xenophon. This wild honey is derived from the flowers of Rhododendrons (the national flower of Nepal). Honey consumption toxicity was noted in a few medical students who were treated and the current paper describes the outcome and the cause of toxicity.

Introduction

Honey is a sweet aliment produced by honey bees (1) and is derived from the nectar of flowers. According to the United States National Honey Board, "honey is a pure product that is not contaminated with any other substance. (2)
Most micro-organisms do not grow in honey due to a low water activity of 0.6(3) except dormant endospores of the bacterium Clostridium botulinum, which can be dangerous and may even cause death (4).

For at least 2700 years, honey has been used by humans to treat a variety of ailments through topical application. Recently, honey has been found to have some antiseptic and antibacterial properties. Wild honey toxicity symptoms include dizziness, weakness, excessive perspiration, nausea, and vomiting. Less commonly, low blood pressure, shock, heart rhythm irregularities and convulsions may occur, with rare cases resulting in death if consumed in large quantities.

Supportive therapies are the principal management strategies. Morphological identification of the poisonous plant is helpful. Laboratory studies can sometimes determine the toxins. The current report is a series of cases of grayanotoxin poisoning after the ingestion of wild honey derived from the flowers of Rhododendron simsii. The diagnosis was established by the typical clinical features and the detection of the toxin in the specimen of wild honey consumed by doctors and medical students, which was procured by the first author after examining the cases in the hospital ICCU.

Case Report

Case Report Of Wild Honey Intoxication

In this series, seven cases of medical students (age 20-25 years, males) are reported. All of them went to the same restaurant, nearly on an empty stomach for dinner. In spite of the warning from the owner, they consumed large varying amounts of wild honey [10 tablespoons full to 2-3 tablespoons full] before consuming their dinner. The one who consumed the largest amount of honey could eat only half the meal before gastro-intestinal (GI) symptoms developed. In the rest of the students, there was a latent period of 15-20 min. before G.I. symptoms developed. One of the authors consumed 1 tablespoon full of the same sample of honey later, but he developed no symptoms (included in (Table/Fig 1))

Case Report Of Wild Honey Intoxication

In spite of the warning from the owner, they consumed large varying amounts of wild honey [10 tablespoons full to 2-3 tablespoons full] before consuming their dinner. The one who consumed the largest amount of honey could eat only half the meal before gastro-intestinal (GI) symptoms developed. In the rest of the students, there was a latent period of 15-20 min. before G.I. symptoms developed. One of the authors consumed 1 tablespoon full of the same sample of honey later, but he developed no symptoms (included in (Table/Fig 1).

History Of Present Illness
Except one case, all of them developed symptoms after 15-20 minutes of wild honey consumption. All of them developed a burning sensation in the throat, excessive salivation, nausea and vomiting. These were followed by eye symptoms of diplopia, blurring of vision, dilated pupils and a sluggish reaction to light and the cardio-vascular symptoms of palpitation and hypotension. Lastly, symptoms of CNS developed in the form of unconsciousness, deep gasping respiration, respiratory depression and apnea. The severity of the symptoms depended upon the quantity of wild honey consumed. The detailed symptomatology is given in (Table/Fig 1).

GI SYMPTOMS: Burning in throat and epigastrium, Vomiting. Vomit contained food particles & honey, along with frothy fluid.
EYE SYMPTOMS: Diplopia, Blurring of vision, dilated pupil, and sluggish reaction to light.
CVS SYMPTOMS: Palpitation, hypotension
CNS: Black out, unconsciousness, deep gasping, apnea


Physical Examination
The general condition of all cases was fair. The pulse ranged from 48-82/min, B.P. 80-110/ 40-80 mm of Hg. The rest of the systemic examination was normal except for papillary signs, respiratory depression, gasping unconsciousness, nausea and vomiting. The vomit consisted of food particles and wild honey, but did not contain blood.

Investigations
Blood T.L.C. = 4300-9800 cubic mm (4.3-10.8 x10 3 mm) , DLC= N= 58-78% (40-80%), L= 22-42%( 20-40%), Hb 11.8-15% gm% (13- 18 gm% ), Blood Urea =18.8- 33mg% (20-40mg%), serum createnin= 0.9-1.4(0.6-1.2 mg/dl), Na+ = 139-143 meq/L(135-14.5 meq/L), K+ = 3.7- 5.0 meq/L (3.5-5.0 meq/L), The blood group in one case was group A, in three cases was group B, total bilirubin was 0.8-09( 0.8-0.9), , direct bilirubin was 0.2, SGPT was 16-26( 7-56 U/L)s, SGOT was 19-31( 5-35 U/L) , A.L.P.was 172-209 (20- 160 U.L) and random blood sugar was 88- 108 mg/dl( 70-110 mg/dl).

Discussion

The common factors of the above seven cases were;
a. All of them were either medical students or young doctors of 22- 25 years, males, non smokers, but occasional users of alcohol.
As they were medical persons who had a better understanding of their signs and symptoms and as they stayed near the hospital, they reported early to the hospital. The signs and symptoms and the onset of illness were proportional to the amount of honey consumed, as shown in (Table/Fig 1).

It was reported by the restaurant owner that the wild honey was brought from Sagarmatha, Dolakha jilla, from the jungles (south of Jari) from Lincon Bazaar, near which Rhododendrons grew in abundance.
Xenophon described the odd behaviour of Greek soldiers after having consumed honey in a village surrounded by rhododendrons. Later, it was discovered that the honey resulting from these plants have a slightly hallucinogenic and laxative effect. The suspect rhododendrons are Rhododendron ponticum and Rhododendron luteum (formerly Azalea pontica), both of which are found in northern Asia Minor. Eleven similar cases have been documented in Istanbul Turkey during the 1980s (5).
In October 2004, in the Emergency Medical Journal, a similar report was published from Turkey about a series of 19 cases of honey poisoning. (6). A neurotoxin found in the nectar of certain species of rhododendrons (Rhododendron spp.) and laurels (Kalmia spp.) and in unprocessed foods produced from the nectar such as unpasteurized honey, was found to cause temporary effects such as nausea, vomiting, dizziness and irregular heartbeat if ingested.(7).
Several cases of grayanotoxin poisonings in humans have been documented in the 1980s. These cases were reported from Turkey and Austria. The Austrian case resulted from the consumption of honey that was brought back from a visit to Turkey. From 1984 to 1986, 16 patients were treated for honey intoxication in Turkey. The symptoms started approximately 1 hr after 50 g of honey was consumed. In an average of 24 hrs, all of the patients recovered. The case in Austria resulted in cardiac arrhythmia, which required a temporal pacemaker to prevent further decrease in the heart rate. After a few hours, pacemaker simulation was no longer needed. The Austrian case shows that with increased travel throughout the world, the risk of grayanotoxin poisoning is possible outside the areas of Ericaceae-dominated vegetation, namely, Turkey, Japan, Brazil, United States, Nepal, and British Columbia. In 1983, several British veterinarians reported an incident of grayanotoxin poisoning in goats. One of the four animals died. The post-mortem examination showed grayanotoxin in the lumen contents. (8)
Another report from Turkey in 2007 describes asystoles in a 60 year old patient who ingested wild honey derived from the flowers of rhododendron. (9) This was followed by another report from the same authors in which they questioned the necessity of hospitalization following wild honey poisoning (10)
Our cases are similar to previously published reports. According to FDA, a neurotoxin found in the nectar of certain species of rhododendrons (Rhododendron spp.) and laurels (Kalmia spp.) and in unprocessed foods produced from the nectar, such as unpasteurized honey, was found to cause temporary effects such as nausea, vomiting, dizziness, and irregular heartbeat if ingested. The intoxication is rarely fatal and generally lasts for no more than 24 hours. Generally, the disease induces dizziness, weakness, excessive perspiration, nausea and vomiting shortly after the toxic honey is ingested. Other symptoms that can occur are low blood pressure or shock, bradyarrhythima (slowness of the heart beat associated with an irregularity in the heart rhythm), sinus bradycardia (a slow sinus rhythm with a heart rate less than 60), nodal rhythm (pertaining to a node, particularly the atrioventricular node), Wolff-Parkinson-White syndrome (anomalous atrioventricular excitation) and complete atrioventricular block (8).

Mechanism Of Action Of Grayanotoxin
The grayanotoxins bind to sodium channels in cell membranes. The binding unit is the group II receptor site, localized on a region of the sodium channel that is involved in the voltage-dependent activation and inactivation. These compounds prevent inactivation; thus, excitable cells (nerve and muscle) are maintained in a state of depolarization, during which entry of calcium into the cells may be facilitated. This action is similar to that exerted by the alkaloids of veratrum and aconite. All of the observed responses of skeletal and heart muscles, nerves, and the central nervous system are related to the membrane effects (8).

Conclusion

The increased desire of the public for natural (unprocessed) foods may result in more cases of grayanotoxin poisoning. Individuals who obtain honey from farmers who may have only a few hives are at increased risk. The pooling of massive quantities of honey during commercial processing generally dilutes any toxic substance which may be present. The public should consume only reliable branded forms of honey which are obtained from reliable sources in order to avoid honey intoxication.
