"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."

"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".

"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."

"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."

We report a case of painless dissecting aneurysm, mainly involving the descending aorta in a 46-year old Philippine patient, who was admitted to our hospital, presenting with cerebrovascular accident. His medical history was remarkable for hypertension for 9 years. The patient did not have chest or back pain. On clinical examination, it was observed that he had left sided hemiplegia. Computed tomography (CT) of the head showed multiple infarctions. Trans oesophageal echocardiography and Magnetic Resonance Imaging of the chest and abdomen showed dissecting aneurysm in the descending thoracic aorta with big thrombus. The patient was treated conservatively and was discharged in good condition.


Cerebrovascular accident. dissecting aneurysm.

Aortic dissection is defined as the separation of the layers within the aortic wall. Tears in the intimal layer result in the propagation of dissection (proximally or distally), secondary to blood entering the intima-media space, (1) often presenting with tearing chest pain and acute haemodynamic compromise. Its prompt diagnosis remains essential for successful management (2). Aortic dissection can be diagnosed premortem or postmortem because many patients die before presentation to the emergency department (ED) or before diagnosis is made in the ED. We report a 46-year-old Philippine male, who presented with painless Aortic dissection.

Case Report

A 46-year-old Philippine gentleman, a known case of hypertension for 9 years, was admitted to the emergency department with sudden onset of slurred speech and weakness on the left side of the body that occurred early morning after waking from sleep. There was no history of any chest or abdominal pain.On examination, the patient was found to be fully conscious (Glasgow Coma Scale score of 15/15)Blood pressure was 170/100, the pulse rate was 61/minute regularly palpated over both femoral and radial arteries, body temperature was 36.7 and respiratory rate was 14/minute.

On Neurological exam, there was upper motor left facial palsy, dysarthria and left sided hemiplegia with power of grade 2/5 in the left upper and lower limbs with upgoing planter on the left side. There was no carotid bruit. Cardiac auscultation revealed normal first and second heart sound with no added sound or murmur. The lungs were clear to auscultation. There was no abnormal finding on his 12-lead electrocardiogram. His Chest X ray showed widened mediastinum with dilated ascending and descending part of aorta (Table/Fig 1). Laboratory findings showed high serum creatinine- 175µmol/l, Urea- 9 mmol/l, Sodium -139mmol/l, Chloride- 104mmol/l, Bicarbonate -23mmol/l, potassium -3.7mmol/l and sugar -6.53mmol/l. Non enhanced Computed tomography (CT) of the head showed multiple bilateral Centrum semi ovale, right frontal, right basal ganglia, and right cerebellar lacunar infarcts. Magnetic Resonance Imaging (MRI) of brain was performed, which showed the same results as in the CT finding. Moreover, Intra cranial Magnetic resonant angiography (MRA) was normal.

In the view of these findings (multiple sites of infarction and dilated mediastinum), trans oesophageal Echocardiography (Table/Fig 2) was done, which showed dissecting aneurysm in the descending thoracic aorta, with the dissecting flap seen in the aortic arch along the descending thoracic aorta, up to 40 cm from the incisors. The false lumen measured 2.2 cm and the true lumen measured 1.2 cm. There was an aortic arch thrombus occupying the most proximal part of the dissecting flap and filling the false lumen, measuring 1.6 cm.MRI of the chest and abdomen (Table/Fig 3) showed extensive aortic dissection starting from the aortic arch, with false lumen starting proximal to but not involving the origin of the subclavian artery, extending to the lower most part of the abdominal aorta with the false lumen larger than the true lumen.

Kidney dimensions checked by ultrasound were within normal limits (right kidney 9.3 Cm and left kidney 9.4 cm), whereas MR Angiography of the renal arteries revealed extensive aortic dissection with perfusion of the right kidney from the true lumen and the left kidney from the false lumen, with the short stenotic segment at the origin of the left renal artery of less than fifty percent, which was regarded as hemodynamically non significant. As the dissecting process involves the descending aorta, the patient was treated conservatively with aggressive control of blood pressure and rehabilitation. After 4 weeks, his creatinine levels returned back to normal spontaneously and he was discharged from hospital in a good condition


Aortic dissection occurs most often because of a tear or damage on the inner wall of the artery. It is found that theincidence of acute aortic dissection in the general population ranges from 2.6 to 3.5 per 100,000 person-years (3),(4),(5) with males more frequently affected than females, with a ratio ranging from 2:1–5:1(6). While its occurrence is relatively uncommon before the age of 40, when it does occur, it is usually in association with certain predisposing factors (7) and mainly affects the sixth and seventh decades.

There are two Classifications for Aortic dissection, the DeBakey and Daily (Stanford) systems, (18),(8),(9). The Stanford system is more widely used. It classifies dissections that involve the ascending aorta as type A, regardless of the site of the primary intimal tear, and all other dissections as type B. In comparison, the DeBakey system is based upon the site of origin, with type 1 originating in the ascending aorta and propagating to at least the aortic arch, type 2 originating in and confined to the ascending aorta, and type 3 originating in the descending aorta and extending distally or proximally.

The main predisposing factor for acute aortic dissection is systemic hypertension, which presents itself in 72 percent of the patients, while the second is atherosclerosis, which is seen in 31 percent (10) of the patients. On the other hand, other predisposing factors include chromosomal aberrations, hereditary abnormal connective tissue, congenital aortic valve defects, coarctation of the aorta, inflammatory or infectious abnormalities, pregnancy (especially the third trimester), annuloaortic ectasia and aortic aneurysm (6). In our case, the predisposing factor was hypertension.

The most common presentation is the acute onset of severe chest or back pain, although painless and/or atypical symptoms have been documented(11),(13). In an analysis from the IRAD registry, painless dissection has been found to be reported in (6.4 percent)(14) of patients; mainly in the elderly and diabetic patients and in those with aortic aneurysm, or cardiovascular surgery.

In one study, up to ten percent of patients with painless AD presented with neurological symptoms (15). Our case presented without chest, back, or abdominal pain.

In painless aortic dissection, the explanation for absence of pain is still a matter of debate (16). More than one theory had been proposed (17),(18), like slow or gradual dissection with less wall stretching and sparing of the adventitial layer, the site of aortic innervations.

Involvement of the ascending aorta leads to neurological deficits including stroke or decreased consciousness due to direct extension of the dissection into the carotid arteries or due to diminished carotid blood flow (19). On the other hand, involvement of the descending aorta leads to focal neurological deficits due to spinal artery involvement and spinal cord ischaemia. (20),(21). In our case, the presentation was with multiple infarction and left sided hemiplegia.

Management of renal impairment due to dissecting aorta depends on its severity. Stents were used in more than one report, while others preformed surgical interventions; but our patient was managed conservatively and he regained his renal function. In general, for any hypertensive patient coming to the emergency department with CVA with multiple infarctions, renal failure with or without chest pain should raise the suspicion of aortic dissection.
