" 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".

"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

Madura’s foot is a rare infectious granulomatous disease affecting the foot. The incidence of this disease has decreased in recent years due to improved living conditions. However, it can still be misdiagnosed by inexperienced surgeons as other similar conditions. Early and accurate diagnosis is crucial for optimal treatment and limb preservation. In this study, the authors present three unusual cases of Madura’s foot. A 23-year-old woman presented with swelling and draining sinuses in her left foot for six years. Imaging tests including Ultrasonography (USG), Computed Tomography (CT), and Magnetic Resonance Imaging (MRI) revealed the characteristic ‘dot in circle’ sign of Madura’s foot. However, her USG-guided biopsy did not confirm the diagnosis, and it was only through an excisional biopsy that actinomycetoma was confirmed. Another case involved a 60-year-old male with multiple soft tissue swellings on his right foot for 10 years, resulting in foot deformity. Radiographs showed multiple punched-out lytic lesions in the bones, while USG and MRI exhibited the typical ‘dot in a circle’ sign. Histopathological examination confirmed actinomycetoma. The third case involved a 36-year-old male with a chronic sinus discharging yellow pus and black granules on the volar side of his right foot. USG and MRI revealed the classic signs of Madura’s foot, and these findings were correlated with histopathological examination. The present cases confirm the specificity of the ‘dot-in-circle’ sign on MRI and USG, supported by histopathological correlation.

Mycetoma is a chronic, slowly developing granulomatous infection that affects the skin and subcutaneous tissue. Its primary symptoms include swelling, discharge-producing sinuses, and granules in the discharge. The infection typically occurs through penetrating injuries or repeated minor trauma (1). The foot and hand are the most commonly affected sites (2). While microbiological culture and biopsy are reliable diagnostic methods, they can be time-consuming and may not provide a definitive diagnosis for organisms with complex nutritional requirements that are difficult to grow on standard culture media (3).

Case Report

Case 1

A 23-year-old female patient presented to a tertiary care centre in Northern India with multiple swellings and draining sinuses on the dorsal aspects of her left foot, which had been present for six years (Table/Fig 1)a. On examination, the patient had no fever or palpable nodes in the regional areas. The dorsal aspect of the left foot showed black discoloration, several ill-defined swellings, and multiple non-tender sinuses with yellowish discharging grains. Culture and sensitivity testing of the purulent discharge revealed Staphylococcus aureus with no fungal growth. Conventional Radiograph (CR) of the left foot showed soft tissue prominence on the dorsal aspect (Table/Fig 1)b. Ultrasonography (USG) revealed the characteristic ‘dot in circle’ sign with surrounding inflamed fat (Table/Fig 1)c. Non-Contrast Computed Tomography (NCCT) depicted superficial erosions of multiple metatarsals (Table/Fig 2)a-d. Magnetic Resonance Imaging (MRI) of the left foot revealed multiple nodular lesions with a peripheral rim, creating a target-like “dot-in-circle” appearance (Table/Fig 2)e.

The patient was treated with the Modified Welsh regimen, consisting of three cycles of intravenous Amikacin (500 mg) for 21 days each, followed by a four-week regimen of oral Trimethoprim (160 mg) - Sulfamethoxazole (800 mg) combination twice a day. Medical treatment resulted in complete recovery of all sinuses. The patient later underwent surgery (Table/Fig 3)a-c and continued the oral Trimethoprim 160 mg - Sulphamethoxazole 800 mg combination twice a day, along with Rifampicin 600 mg once a day for one month.

The excised specimen was sent for histopathological examination (Table/Fig 4)a,b. The histopathological findings showed dense suppurative granulomas surrounding the Actinomyces colony and radiating filamentous organisms, confirming actinomycetoma (Table/Fig 4)c,d. The patient remained symptom-free for six months after surgery (Table/Fig 3)c and has been regularly followed-up for the past two years without recurrence of symptoms. The patient expressed satisfaction with the treatment.

Case 2

A 60-year-old male farmer presented to the plastic surgery department and radiology department of a tertiary care centre in Northern India with multiple soft tissue swellings on the dorsal aspect of his right foot, along with progressive deformity, for 10 years (Table/Fig 5)a,b. The patient initially experienced painless swelling, which gradually grew in size. Over the past two years, the swelling has caused difficulty in walking, wearing footwear, and continuing farming activities. The swelling eventually led to foot deformity.

On examination, the patient had no fever or lymphadenopathy. The dorsal aspect of the right foot showed discolouration, multiple swellings with ill-defined borders, and non-tender firmness without fluctuation. Several draining sinuses were also present. Conventional Radiograph (CR) of the right foot showed soft tissue prominence with multiple punched-out lytic lesions in the tarsal and metatarsal bones, along with toe deformity (Table/Fig 6)a,b. The post-operative follow-up clinical image of the patient is shown in (Table/Fig 6)c. Ultrasonography (USG) and Magnetic Resonance Imaging (MRI) showed the characteristic ‘dot in circle’ sign consistent with Madura’s foot (Table/Fig 7)a,b. Microbiological investigations were inconclusive. The patient was treated with oral Itraconazole 200 mg twice a day for six months, resulting in a decrease in the number of discharging sinuses. Below-knee amputation was advised, and the patient underwent the procedure. Pus culture revealed Staphylococcus aureus growth. Excisional biopsy of the lesion was sent for histological analysis, which showed giant cells with sulfur granules. Histopathological examination revealed balls of eosinophilic radiating filaments surrounded by dense mixed inflammatory infiltrates (Table/Fig 7)c. PAS staining showed positively stained colonies, confirming the diagnosis of eumycetoma. After one year of follow-up, the patient remained free of previous symptoms (Table/Fig 6)c. The patient expressed satisfaction with the treatment received.

Case 3

A 36-year-old male farmer presented to the dermatology department of a tertiary care centre in Northern India with a chronic sinus discharging yellow pus with black granules on the dorsal side of his right foot for six months, which started after a thorn prick on the foot. On examination, the patient had a normal temperature and no lymphadenopathy. Conventional Radiograph (CR) showed prominent soft tissue on the dorsal aspect of the foot (Table/Fig 8)a. Ultrasonography (USG) (Table/Fig 8)b and Magnetic Resonance Imaging (MRI) (Table/Fig 8)c depicted the classic ‘dot in circle’ sign of Madura’s foot. Pus culture revealed no growth, but cytology and biopsy (Table/Fig 8)d confirmed Actinomycetoma. The patient received antibiotic therapy for actinomycetoma (same as the first patient) for six months, followed by surgery. After completing the treatment, the patient was symptom-free with no residual sinus. During a three-year follow-up, the patient did not develop any new symptoms and expressed full satisfaction with the treatment.

Discussion

In recent years, the “dot-in-circle” sign has emerged as a highly specific indicator of mycetoma on Ultrasound (USG) and Magnetic Resonance Imaging (MRI), allowing for non-invasive and early diagnosis (3). This unique sign has demonstrated the value of USG and MRI in diagnosing mycetoma at an early stage. USG, being a more affordable and widely available imaging modality, can be used as the first-line approach to confirm the diagnosis.

Mycetoma is a localised granulomatous infection of subcutaneous tissue caused by actinomycetes (actinomycetoma) or fungi (eumycetoma), commonly seen in Africa and Asia (4). Without timely intervention, mycetoma can result in lifelong disabilities (5),(6),(7).

Radiological imaging, including Conventional Radiograph (CR), USG, MRI, and Non-Contrast Computed Tomography (NCCT), is necessary to assess the extent of the lesions and aid in surgical planning (7),(8). CR is performed to determine if there is involvement of the bone, as non-surgical treatment becomes challenging in such cases (8). Advanced mycetoma can be identified on CR by radiological markers such as bone erosions, cavities, periostitis, bony sclerosis, and soft tissue edema (3). USG is a more specific imaging modality than CR for detecting mycetoma and is commonly used in its diagnosis (9). The “dot-in-circle” sign on MRI is characterised by a dot representing T2 hypointense (dark signal) fungal or actinomycete grains, and a circle denoting the peripheral T2 hyperintense (bright signal) abscess or granuloma with a thin peripheral hypointense line representing fibrous matrix (Table/Fig 9)a. The comparable USG “dot-in-circle” sign consists of circular hypoechoic lesions with a hyperechoic centre (Table/Fig 9)b (3).

Inflammatory tissue appears on MRI as groups of small (2 to 5 mm) spherical hyperintense lesions with hypointense centre that are surrounded by a thin dark (low-signal) ring that represents the intervening fibrous septa. A mycetoma appears to be strongly suggested by the “dot in circle” indicator (3),(7). MRI can better delineate the subcutaneous fat, bones, and muscle involvement precisely and thus can grade the disease, which affects the patient’s management (9). The differentials for the “dots” are phlebolith of haemangioma, though, clinical presentation, scarcer number of the dots, nonappearance of sinuses or inflammation in surrounding tissues favours the finding of slow flow vascular pathology. Other differentials are rice bodies in the fluid of joint or tendon infection, exclusively in tuberculosis or Rheumatoid patients (3). By using a CT scan, the bone involvement in mycetoma can be evaluated.

CR and USG imaging are suitable for local settings and are particularly useful in low-income countries. In advanced cases with bone involvement, surgical intervention is required for a therapeutic cure (5). Timely diagnosis of mycetoma is crucial to prevent functional impairment (10).

On USG, eumycetoma lesions appear as abundant sharp bright hyper-reflective echoes parallel to the dark grains, while actinomycetoma lesions show less discrete echoes due to smaller size and consistency (11). The “Welsh regimen,” which combines co-trimoxazole with amikacin in one to five-week cycles, has been suggested for use in resistant disease. Modifications of the original Welsh regimen may include adding rifampicin, dapsone, or increasing the number of cycles in cases of bony erosion (12). Oral itraconazole (400 mg divided into two doses for six months to three years) is the most commonly used treatment for eumycetoma. Oral antifungal therapy followed by surgical debridement is the preferred approach for treating eumycetoma (13). For a detailed comparison between actinomycetoma and eumycetoma, refer to the related articles and the provided tables (Table/Fig 10),(Table/Fig 11) (14),(15),(16),(17),(18),(19).

Conclusion

Ultrasound (US) and Magnetic Resonance Imaging (MRI) complement each other in the early diagnosis and confirmation of Madura’s foot, characterised by the “dot-in-circle” sign on imaging. These imaging modalities are quick, non-invasive, and simple to use for early diagnosis and assessing the extent of the lesion. While microbiological culture and biopsy are reliable diagnostic methods, they are time-consuming. In one of our patients, cytology and culture yielded false negative results, highlighting the diagnostic accuracy of low-cost and readily available USG imaging for making the diagnosis and initiating timely treatment with favourable clinical outcomes.
