Nasal Biopsy

Intranasal tumors of dogs and cats pose a diagnostic and therapeutic challenge for small animal practitioners. Multiple nasal biopsy techniques have been described in the past. This report describes a simplified flushing technique to biopsy and debulk nasal tumors, which often also results in immediate clinical relief for the patient. Based on the results of this retrospective study, the authors recommend high-pressure saline hydropulsion as a minimally invasive diagnostic, and potentially therapeutic, technique for nasal tumors in dogs and cats.

Aim. To consider the possibility of the diagnosis of a rare small bowel tumour complicated by small bowel obstruction and small bowel bleeding, as well as the surgical treatment of this pathology using a minimally invasive surgical approach.Results and discussion. The authors present a clinical case of associated complication of a gastrointestinal stromal tumour (GIST) of the small intestine in a 48-year-old patient. The patient was admitted to a surgical clinic with small bowel obstruction, episodes of intestinal bleeding and anaemia. The diagnosis was determined using CT enterography. In line with the current trends for minimally invasive surgery, minimally invasive laparotomy was performed drawing on the CT mapping of the anterior abdominal wall. The last stage involved in the morphological verification of GIST, which employs a standard procedure of IHC testing, revealed a malignant GIST, spindle cell variant. The verified histotype of a small intestinal tumour provides the opportunity to choose the necessary variant of adjuvant chemotherapy, as well as to improve general and relapse-free survival.Conclusion. Minimally invasive operations can be performed in the complicated course of GIST due to the biological properties of this pathology (absence of lymphogenic metastasis and infiltrative growth) without decreasing five-year survival rate. The use of CT helps make a topical diagnosis and plan minimally invasive surgical treatment.

Transport Studies

The elemental composition of amino acids is similar to that of the major structural components of the epithelial cells of the small intestine and other tissues. Therefore, their subcellular localization and concentration measurements are not possible by x-ray microanalysis. Radioactive isotope labeling: I131-tyrosine, Se75-methionine and S35-methionine have been successfully employed in numerous absorption and transport studies. The latter two have been utilized both in vitro and vivo, with similar results in the hamster and human small intestine. Non-radioactive Selenomethionine, since its absorption/transport behavior is assumed to be the same as that of Se75- methionine and S75-methionine could serve as a compound tracer for this amino acid.

Crystalline Nature

Trichinella spiralis induces a profound mastocytosis and eosinophilia in the small intestine of the infected mouse. Mouse mast cells (MC) store in their granules various combinations of at least five chymotryptic chymases [designated mouse MC protease (mMCP) 1 to 5], two tryptic proteases designated mMCP-6 and mMCP-7 and an exopeptidase, carboxypeptidase A (mMC-CPA). Using antipeptide, protease -specific antibodies to these MC granule proteases, immunohistochemistry was done to determine the distribution, number and protease phenotype of the MCs in the small intestine and spleen 10 to >60 days after Trichinella infection of BALB/c and C3H mice. TEM was performed to evaluate the granule morphology of the MCs between intestinal epithelial cells and in the lamina propria (mucosal MCs) and in the submucosa, muscle and serosa of the intestine (submucosal MCs).As noted in the table below, the number of submucosal MCs remained constant throughout the study. In contrast, on day 14, the number of MCs in the mucosa increased ~25 fold. Increased numbers of MCs were observed between epithelial cells in the mucosal crypts, in the lamina propria and to a lesser extent, between epithelial cells of the intestinal villi.

Management Of Dysphagia

Esophageal cancer is the sixth leading cause of death from cancer worldwide. Esophageal resection is the mainstay treatment for cancers of the esophagus. While curative, surgical resection may result in swallowing difficulties that require intervention from speech-language pathologists (SLPs). Minimally invasive surgical procedures for esophageal resection have aimed to reduce morbidity and mortality associated with more invasive techniques. Both intra-operative and post-operative complications, regardless of the surgical approach, can result in dysphagia. This article will review the epidemiological impact of esophageal cancers, operative complications resulting in dysphagia, and clinical assessment and management of dysphagia pertinent to esophageal resection.
