Case report on unusual tumor with synchronous cutaneous and gastrointestinal tract involvement

International Journal of Health Sciences, 2021

Histiocytic sarcoma (HS) is an exceedingly rare lymphohematopoietic malignancy with morphological... more Histiocytic sarcoma (HS) is an exceedingly rare lymphohematopoietic malignancy with morphological and immunophenotypic characteristics of mature tissue histiocytes. We report a unique case of a HS with synchronous skin and gastrointestinal tract involvement which has not been reported in literature till date to the best of our knowledge. A 70-year-old male farmer presented with multiple ulcerated skin lesions ranging from 0.5 to 10 cm all over the body. Autopsy revealed multiple transmural nodular deposits in stomach, intestines, head of pancreas, and peripancreatic tissue. Histopathology and immunohistochemistry profile was consistent with HS exhibiting positivity for CD68, CD163, and lysozyme. CD 163 identifies histiocytic malignancies with high degree of specificity and has become a promising marker for their diagnosis.

A Tale of Two Benign Hepatic Nodules with Pulmonary Hypertension

Nodular regenerative hyperplasia and hepatocellular adenoma are two benign liver lesions with low... more Nodular regenerative hyperplasia and hepatocellular adenoma are two benign liver lesions with low risk of malignant potential. Nodular regenerative hyperplasia appears to be result of adaptive reaction to hepatic vasculopathy. Hepatocellular adenoma is associated with use of estrogen, anabolic steroids, metabolic disease and rarely vascular abnormality. We report an unusual case of a young female who presented with progressive dyspnoea, cough and edema. She succumbed to her illness within two days of her hospital stay. A medical autopsy was performed which revealed hepatocellular adenoma arising on the background of nodular regenerative hyperplasia along with pulmonary hypertension and intrapulmonary hemorrhage. Unusual case of nodular regenerative hyperplasia and hepatocellular adenoma associated with pulmonary hypertension where vascular pathology is suggested as a common event in their pathogenesis. Hence, it is advisable to rule out associated conditions with the help of imaging techniques in patients with pulmonary hypertension.

Fish-inspired robots: design, sensing, actuation, and autonomy—a review of research

Bioinspiration & Biomimetics, 2016

Underwater robot designs inspired by the behavior, physiology, and anatomy of fishes can provide ... more Underwater robot designs inspired by the behavior, physiology, and anatomy of fishes can provide enhanced maneuverability, stealth, and energy efficiency. Over last two decades, robotics researchers have developed and reported a large variety of fish-inspired robot designs. The purpose of this review is to report different types of fish-inspired robot designs based upon their intended locomotion patterns. We present a detailed comparison of various design features like sensing, actuation, autonomy, waterproofing, and morphological structure of fish-inspired robots reported in the past decade. We believe that by studying the existing robots, future designers will be able to create new designs by adopting features from the successful robots. The review also summarizes the open research issues that need to be taken up for the further advancement of the field and also for the deployment of fish-inspired robots in practice.

Solitary hamartomatous duodenal polyp in an infant

Journal of pediatric surgery case reports, 2021

Duodenal polyps are uncommon. They are usually syndromic seen commonly with Familial adenomatosis... more Duodenal polyps are uncommon. They are usually syndromic seen commonly with Familial adenomatosis polyposis or Peutz-Jegher's syndrome, but maybe seen as a solitary non-syndromic polyp presenting with gastrointestinal symptoms. Few cases of Solitary duodenal hamartomatous polyps have been seen in adults, but to the best of our knowledge never in an infant. We hereby report a case of a 6week old infant who presented with bilious vomiting, weight loss and dehydration. Radiological investigations revealed an obstructive duodenal polyp. Duodenotomy and excision proved curative.
