Gastric Adenocarcinoma Deposits Presenting as Multiple Cutaneous Nodules: A Case Report with Review of Literature
Aparna NARASIMHA,Harendra KUMAR
Türk Patoloji Dergisi , 2012,
Abstract: Metastases to the skin from internal tumors are uncommon, yet they may be the first presentation of such malignancies. They usually arise from the breast, lung and large bowel. Cutaneous metastases from gastric adenocarcinoma are extremely rare. We report a case of gastric adenocarcinoma that at presentation had multiple clinically benign looking skin nodules. Fine needle aspiration cytology of the cutaneous nodule revealed metastatic deposits. The current literature on cutaneous metastases of gastric carcinoma is reviewed in this case report.
Global Climate Change and Health: Strategies to Overcome the Adverse Effects
Dr Harendra Kumar
Indian Streams Research Journal , 2012,
Abstract: At first global warming sounded like a good idea, especially to people in Northern climes. But starting in the 1960s, scientists recognized long-range problems, concentrating at first on sea-level rise and a threat to food supplies. New items were gradually added to the list, ranging from the degradation of ecosystems to threats to human health. Experts in fields from forestry to economics, even national security experts, pitched in to assess the range of possible consequences.

Vulval schwannoma: A cytological diagnosis
Das Subhashish,Kalyani R,Harendra Kumar M
Journal of Cytology , 2008,
Abstract: Schwannomas are the most common peripheral nerve sheath tumors, the frequent sites of involvement being the head and neck, the flexor aspect of the limbs, especially near the elbow, wrist, knee, and trunk. Involvement of the female genital tract is extremely rare. We present one such rare case of a solitary vulval schwannoma which was diagnosed by fine needle aspiration cytology in a 48 year-old female, and confirmed by histopathological examination.
Scheduling Algorithm: Tasks Scheduling Algorithm for Multiple Processors with Dynamic Reassignment
Pradeep Kumar Yadav,M. P. Singh,Harendra Kumar
Journal of Computer Networks and Communications , 2008, DOI: 10.1155/2008/578180
Abstract: Distributed computing systems [DCSs] offer the potential for improved performance and resource sharing. To make the best use of the computational power available, it is essential to assign the tasks dynamically to that processor whose characteristics are most appropriate for the execution of the tasks in distributed processing system. We have developed a mathematical model for allocating “M” tasks of distributed program to “N” multiple processors (>) that minimizes the total cost of the program. Relocating the tasks from one processor to another at certain points during the course of execution of the program that contributes to the total cost of the running program has been taken into account. Phasewise execution cost [EC], intertask communication cost [ITCT], residence cost [RC] of each task on different processors, and relocation cost [REC] for each task have been considered while preparing a dynamic tasks allocation model. The present model is suitable for arbitrary number of phases and processors with random program structure.
Optimal Tasks Assignment for Multiple Heterogeneous Processors with Dynamic Re-assignment
Harendra Kumar,M. P. Singh,Pradeep Kumar Yadav
International Journal of Computers & Technology , 2013,
Abstract: Distributed Computing System [DCS] has attracted several researchers by posing several challenging problems. In this paper we have developed a mathematical model for allocating “M” tasks of distributed program to “N” multiple processors (M>N) that minimizes the total cost of the program. Relocating the tasks from one processor to another at certain points during the course of execution of the program that contributes to the total cost of the running program has been taken into account. Most of the researchers have considered the cost for relocating the task from one processor to another processor at the end of the phase as a constant. But in real life situations the reallocating cost of the tasks may very processor to processor this is due to the execution efficiency of the processors. Phase-wise execution cost [EC], inter task communication cost [ITCT], residence cost [RC] of each task on different processors and relocation cost [REC] for each task have been considered while preparing a dynamic tasks allocation model.
Retroperitoneal cystic schwannoma: A case report with review of literature
Narasimha Aparna,Harendra Kumar M,Kalyani R,Madan M
Journal of Cytology , 2010,
Abstract: The occurrence of retroperitoneal schwannoma is uncommon and its presence may only be expressed by insidious onset of nonspecific symptoms such as vague abdominal pain. Imaging modalities like computed tomography and magnetic resonance imaging may demonstrate the tumor, but due to heterogeneity and degeneration in some tumors, it may mimic malignancy. So, fine needle aspiration cytology followed by tissue sampling through needle biopsies may be essential to confirm the diagnosis prior to the surgery. This case is reported for its rare clinical presentation, having duration of more than 40 years with cystic degenerative changes.
Plasmacytoma of tonsil diagnosed by fine-needle aspiration cytology
Bhat Ramachandra,Prathima K,Harendra Kumar M,Narayana G
Journal of Cytology , 2010,
Abstract: Extramedullary plasmacytoma of tonsil is rare. Even though biopsy is necessary for final diagnosis, fine-needle aspiration cytology (FNAC) can provide useful information in the management of such cases. We report a case of plasmacytoma of tonsil diagnosed by FNAC in a 43-year-old man who presented with a swelling in the right tonsillar area. FNAC smears revealed sheets of plasma cells at various stages of maturation. Subsequent histopathological and immunohistochemical studies confirmed the diagnosis of plasmacytoma. This case is reported for the rarity of site for extramedullary plasmacytoma and to highlight the usefulness of FNAC in lesions of tonsil.
CD-3 positive extranodal T-cell lymphoma of nasal type with skin involvement
Reddy Raghunatha,Singh Gurcharan,Prathima K,Harendra Kumar M
Indian Journal of Dermatology, Venereology and Leprology , 2006,
Abstract: A 40-year-old previously healthy lady presented with nasal obstruction and localized plaques over the right arm. She developed complete nasal obstruction due to a mass in the right nasal cavity and skin lesions that ulcerated to present as ecthyma gangrenosum like lesions. Patient′s condition deteriorated fast and she developed icterus with fatal outcome within 4 weeks of developing skin lesions. Nasal and skin biopsy revealed angiocentric T-cell lymphoma, which on immuno-phenotyping revealed CD-3 positive; and CD-20, CD-30, ALK and EMA negativity. She was seronegative for HIV. Final diagnosis of CD-3 positive extranodal T-cell lymphoma of nasal type was made. Extranodal T-cell lymphomas are very aggressive NHLs with poor prognosis. Prognosis depends on histology, stage of the disease and sites of involvement. NK/T cell lymphoma of nasal type is common with EBV association. Skin involvement is rare and is also an indicator of poor prognosis.

World Journal of Vaccines (WJV) , 2013, DOI: 10.4236/wjv.2013.32009
Abstract:

Indigenous vaccine developed from native Indian Bison Type strain (S5”) of Mycobacterium avium subspecies paratuberculosis (MAP) of goat origin was first time evaluated in a sheep flock of Bharat Merino breed located in Mannavanur town of Tamil Nadu in South India. Therapeutic efficacy of the vaccine was evaluated for 3 years between 2008 and 2010, on the basis of improvements in productivity (body weights, reproductive efficiency and survivability), physical condition, clinical symptoms (weakness, diarrhea, wool quality), immune response (sero-conversion) and infection load in feces (shedding). After immunization of the flock in 2008, the successive progenies of 112 and 53 lambs born in 2009 and 2010, respectively were vaccinated. Whereas, 40 lambs born to control animals were kept as unvaccinated controls. Though gain in body weights in vaccinated versus controls were not significant in 2008, growth rates were distinctly superior in Ist and IInd generations of vaccinated lambs. Reproductive performance (tupping percent) and survivability of lambs and adult sheep improved significantly. There was overall reduction in yearly morbidity (diarrhea) and mortality rates of the flock in post vaccination years. Shedding of MAP in feces was reduced in vaccinated sheep by 6.2%, 14.3% and 27.3% in 2008, 2009 and 2010 respectively, whereas shedding increased in the control sheep. Seromonitoring of the animals by indigenous ELISA kit showed enhanced flock immunity in successive generations. Indigenous vaccine reduced clinical disease and shedding and improved immunity and productivity of Bharat Merino flock, endemic for Johne’s disease.
