Abstract
Secondary amyloidosis is a well-established entity and has been described in association with chronic inflammatory conditions such as rheumatoid arthritis, ankylosing spondylitis, bronchiectasis, tuberculosis, etc., It has also been reported in association with neoplasms such as Hodgkin's lymphoma, Waldenstrom's macroglobulinemia, renal cell carcinoma, lung carcinoma, etc. However, only a few case reports documenting the association of amyloidosis with gastrointestinal tumor (GIST) and gastric adenocarcinoma are available in the literature. Hereby, we report a case of a 74-year-old male who presented with colicky abdominal pain and vomiting. Ultrasonography revealed a common bile duct (CBD) stone and a small extra-luminal gastric mass. Endoscopic retrograde cholangiopancreatography (ERCP) was performed to remove the CBD stone which revealed an incidental finding of gastric ulcer. A biopsy was taken from the gastric ulcer which on histopathological examination was confirmed as adenocarcinoma leading onto total gastrectomy. During total gastrectomy, an inadvertent injury to the spleen led to simultaneous splenectomy. Multiple samples from the gastric ulcer, the extra-luminal gastric mass, and the spleen were subjected to histopathological examination. Gastric ulcer was confirmed as adenocarcinoma, gastric extra-luminal mass was confirmed as GIST, and splenic examination revealed widespread deposition of amyloid which on Congo-red stain imparted an apple-green birefringence on polarizing microscopy. To the best of our knowledge, this is the first-ever case of such an association where gastric adenocarcinoma occurred with concomitant gastric GIST and secondary amyloidosis of the spleen.

Abstract
BACKGROUND Transformation and progression of lymphoma after treatment is well known; however, since the advent of chemotherapy and radiotherapy, progression in untreated lymphoma is seldom seen. We present a case which was misdiagnosed and treated as abdominal tuberculosis later presented with progression and involvement of oral cavity. CASE PRESENTATION A 41-year-old male who presented with urinary symptoms and abdominal pain was diagnosed as abdominal tuberculosis and treated. Two years later, he presented with B symptoms and oral cavity lesion that was diagnosed as diffuse large B cell lymphoma. The patient was treated with R-CHOP chemotherapy with complete regression of the lesion. CONCLUSION Involvement of extranodal sites in predominantly nodal disease does occur; however, involvement of oral cavity is rare. Though primary extranodal lymphoma is reported to occur in oral cavity and oropharynx, natural progression in untreated disease is seldom documented.

Abstract
Oral squamous cell cancer (OSCC) is a common malignancy attributed to use of chewing smokeless tobacco and smoking. Most of the targeted strategies are based on EGFR expression and mutation; however, none of them has shown significant improvement in survival and response rates. We carried out this study to evaluate mutational profile of tobacco associated oral carcinoma with special emphasis on EGFR and its downstream events. PATIENTS AND METHODS A total of 46 histologically proven cases were recruited between January 2017 and January 2019. Apart from detailed clinical and histological studies, the paraffin-embedded tissue was submitted for expression of 50 genes using Next Generation Sequencing using Ion Ampliseq Cancer Hotspot Panel v2. RESULTS The mean age of patients was 47.8 ± 10.9 years. Majority had tumors on buccal mucosa (24) and tongue (13). Nineteen of these tumors were larger than 4 cm, and 5 had adjacent site involvement. Thirty one were node positive. TP53 mutations were commonest seen in 19 followed by CDKN2A in 11, HRAS in 8, PIK3CA in 3, SMARCB1 in 2, and KIT, EGFR, BRAF, STK11, ABL1, RB1 in one case each. Concomitant TP53 mutation was identified with other mutations like CDKN2A, HRAS, KIT, PIK3CA, STK11, SMARCB1, ABL1, and RB1 making tobacco-associated OSCC as a heterogeneous mutational tumor with multiple events. A patient with TP53 mutations has poor disease free survival (47.4 vs 63% p = 0.17); however, this was not statistically significant. CONCLUSION The study shows a heterogeneous mutational spectrum with multiple mutational events in OSCC. The low EGFR mutation rates and higher mutations in EGFR downstream pathways including that in TP53 and HRAS suggest that anti EGFR strategies may not succeed in these tumors and newer agents and therapeutic combinations need to be tried.

Abstract
This is a case report of 45-year-old woman with recurrent phyllodes tumour. Although these tumours are not very rare and one finds them occasionally in day-to-day practice, we report here a case of recurrent phyllodes tumour that was treated by a simple mastectomy 1 year back, and it recurred very fast and attained enormous dimensions without any local ulceration.

Abstract
Diaphragmatic injuries can occur with both blunt and penetrating trauma which can be associated with herniation of abdominal viscera into the thoracic cavity. Diaphragmatic injuries can occur with blunt trauma chest in 1-7 % of patients. Retrospectively for last 3 years all cases blunt trauma chest admitted to surgery were reviewed and a study of cases of diaphragmatic rupture was done. We analysed 496 patients of blunt trauma chest retrospectively for period of three years. Nine patients have diaphragmatic injuries, all were males, six presented acutely three were chronic. In six patients laparotomy was done, four subcostal and two midline incisions were preferred. In chronic cases thoracotomy was done. Left sided injury predominates and rib fractures are most common associated finding. Diagnosis in majority of cases is made by Computerised tomography scan. Subcostal incision may be used in patients with isolated diaphragmatic injury in acute presentation while thoracotomy is preferred in late cases. Most common morbidity is pulmonary complications.

Abstract
The authors proposed a simple, rapid and sensitive liquid chromatography-tandem mass spectrometric (LC-MS/MS) assay method for the simultaneous determination of saxagliptin and its active metabolite 5-hydroxy saxagliptin in human plasma. The developed method was fully validated as per the US FDA guidelines. The method utilized stable labeled isotopes saxagliptin-15 N d2 (IS1) and 5-hydroxy saxagliptin-15 N-d2 (IS2) as internal standards for the quantification of saxagliptin and 5-hydroxy saxagliptin, respectively. Analytes and the internal standards were extracted from human plasma by a single step solid-phase extraction technique without drying, evaporation and reconstitution steps. The optimized mobile phase was composed of 0.1% acetic acid in 5 mM ammonium acetate and acetonitrile (30:70, v/v) and delivered at a flow rate of 0.85 mL/min. The method exhibits the linear calibration range of 0.05-100 ng/mL for both the analytes. The precision and accuracy results for both the analytes were well within the acceptance limits. The different stability experiments conducted in aqueous samples and in matrix samples are meeting the acceptance criteria. The chromatographic run time was set at 1.8 min; hence more than 400 samples can be analyzed in a single day.

Abstract
Steam gasification of two different refuse derived fuels (RDFs), differing slightly in composition as well as thermal stability, was carried out in a fixed-bed reactor at atmospheric pressure. The proximate and ultimate analyses reveal that carbon and hydrogen are the major components in RDFs. The thermal analysis indicates the presence of cellulose and plastic based materials in RDFs. H2 and CO are found to be the major products, along with CO2 and hydrocarbons resulting from gasification of RDFs. The effect of gasification temperature on H2 and CO selectivities was studied, and the optimum temperature for better H2 and CO selectivity was determined to be 725 degrees C. The calorific value of product gas produced at lower gasification temperature is significantly higher than that of gas produced at higher process temperature. Also, the composition of RDF plays an important role in distribution of products gas. The RDF with more C and H content is found to produce more amounts of CO and H2 under similar experimental conditions. The steam/waste ratio showed a notable effect on the selectivity of syngas as well as calorific value of the resulting product gas. The flow rate of carrier gas did not show any significant effect on products yield or their distribution.
