Abstract
Today, endoscopic ultrasound-guided radiofrequency ablation has become increasingly accepted for the treatment of different precancerous and neoplastic lesions of the pancreas, particularly in patients who are unfit for surgery. However, thermal ablation has long been suspected to induce pancreatitis or to injure adjacent structures. Published case reports and case series on this topic are of limited size and are often based on a heterogeneous study population, reporting on functional and nonfunctional pancreatic neuroendocrine tumors. Nevertheless, the overall results are promising, with high technical success and relatively low complication rates.

Abstract
Extrahepatic biliary tract and gallbladder neoplastic lesions are relatively rare and hence are often underrepresented in the general clinical recommendations for the routine use of ultrasound (US). Dictated by the necessity of updated summarized review of current literature to guide clinicians, this paper represents an updated position of the Italian Society of Ultrasound in Medicine and Biology (SIUMB) on the use of US and contrast-enhanced ultrasound (CEUS) in extrahepatic biliary tract and gallbladder neoplastic lesions such as extrahepatic cholangiocarcinoma, gallbladder adenocarcinoma, gallbladder adenomyomatosis, dense bile with polypoid-like appearance and gallbladder polyps.

Abstract
This study aimed to determine the diagnostic yield of fine-needle aspiration cytology (FNAC) in salivary gland lesions compared to histopathological diagnosis. The present study was done on patients above 18 years of age, with a palpable swelling, who are clinically diagnosed as salivary gland lesions were evaluated. A total of 31 patients were evaluated in this study. The mean age of the patients was 41 years ± 16.08. The male to female ratio of patients evaluated in our study was 1: 1.066, with a marginal preponderance in the female population. There was a higher incidence of carcinoma in females than males. Parotid gland lesions comprised 83.9% of all the salivary gland lesions analyzed, while submandibular gland lesions comprised 16.1%. In our study, the distribution between non-neoplastic, neoplastic benign, and neoplastic malignant lesions was 9.6%, 83.8%, and 6.4%. The overall diagnostic accuracy for non-neoplastic and neoplastic lesions is 90.3%, with a sensitivity of 89% and a specificity of 100%. The segregation of the results into the positive and negative class of diagnostic outcomes shows 80.6% for true positive, 9.7% for true negative, 0% for false-positive, and 9.7% for false-negative reports. Diagnostic accuracy in differentiating non-neoplastic and neoplastic lesions is 90.3%, with a sensitivity and specificity of 89.0% and 100%, respectively. The diagnostic accuracy of FNAC in differentiating benign from malignant lesions in our study is 93.5% (29 out of 31), the sensitivity of FNAC in our study for diagnosing malignancy is poor, and the specificity is 100%. It can be concluded that FNAC is more accurate in diagnosing benign lesions and more specific than sensitive in diagnosing malignant lesions.

Abstract
Distal fibula resection is a procedure that has been described as early as 1938 for the treatment of neoplastic lesions. There have been several techniques described for the reconstruction of the remaining tibiotalar joint to prevent deformity and maintain as much function as possible. While these reconstruction techniques provide an option for limb salvage with the removal of disease, patients are faced with chronic pain, loss of function, valgus instability, need for long term orthosis, early arthritis, or significant morbidity related to proximal dissection and disruption of native knee anatomy. We present a case series that is compliant with PROCESS1 criteria to demonstrate the effective treatment with distal fibular excision and a reconstruction technique inspired by the original Tommy John procedure of the elbow. This procedure has allowed these two patients long-term stability of the ankle, maintenance of full function, and high levels of function. The first case is a 23-year-old female with high-grade osteosarcoma and the second patient is a 19-year-old female with Ewing sarcoma. Details of the procedure as well as clinical and radiographic follow up of these two patients will be described.

Abstract
Background: Skin cancer is one of the most common types of cancer and its annual mortality rate is increasing. The induction enzyme of cyclooxygenase COX-2 causes biosynthesis of prostaglandin and thromboxane during inflammation of the body. Increasing the expression of COX-2 has an important role in the development and progression of malignant epithelial cancers and other types of cancers. Considering the diagnostic status of the marker, this study aimed to evaluate the expression of COX-2 for diagnosis and differentiation of benign skin pigmented neoplastic lesions from malignant melanoma types. Methods: In this diagnostic study, the immunohistochemistry of COX-2 maker in 82 paraffin blocks of pigmented benign and malignant skin neoplasms of patients (49 men; 33 women) and its association with clinicopathological features of the tumor was evaluated. Data were analyzed using chi-squared and t test in SPSS18. Significance level was set at less than 5%. Results: The findings showed that 20 patients (24.3%) had malignant melanoma and 13 had significant COX-2 (3+ High), while COX-2 marker was not detected in other benign and malignant pigmented skin neoplasms (p<0.001). A significant association was found between COX-2 marker and grade (p<0.001), but there was no significant correlation with other clinicopathological tumor criteria. Sensitivity, specificity, PPV and NPV value of the COX-2 marker were 65%, 100%, 89.9%, and 100%, respectively. Conclusion: Because of the high level of COX-2 in malignant melanoma skin marker, it can be used to distinguish benign and malignant neoplastic lesions (SCC and BCC) from melanoma and to provide effective therapeutic strategies through specific COX-2 enzyme inhibitors.

Abstract
OBJECTIVES To investigate metastasis associated in colon cancer 1 (MACC1) and MET expression in colorectal adenoma, Tis, early-stage invasive (T1 and T2), and advanced adenocarcinoma with liver metastasis using immunohistochemistry. METHODS Ninety-three paraffin-embedded colorectal tumor specimens were immunohistochemically analyzed for MACC1 and MET protein expression. RESULTS MACC1 expression was upregulated in the transition from adenoma to Tis; its expression was further elevated during tumor progression from Tis to early invasive carcinoma. MET expression was constant from adenoma to Tis and to T1 but significantly increased as tumor progression to T2. Both MACC1 and MET expression were enhanced in advanced carcinoma with liver metastasis. CONCLUSIONS Stepwise elevation of MACC1 expression in key points of colorectal cancer development suggests that MACC1 may contribute to cancer initiation and early invasive growth. High expression of both MACC1 and MET may relate to distant metastasis.

Abstract
The present study was carried out to investigate the protective role of Triphala (a combination in equal proportions by weight of fruit powder of Terminalia belerica, Terminalia chebula and Emblica officinalis) against 1,2-dimethylhydrazinedihydrochloride (DMH) induced Endoplasmic reticulum stress (ER stress) in mouse liver. An oral dose of 3 mg/kg body wt in drinking water for 5 weeks significantly (P < 0.001) increased the levels of serum glutamate oxaloacetate transaminase (SGOT), serum glutamate pyruvate transaminase (SGPT), serum Alkaline phosphatase (ALP) and total bilirubin thus suggesting damage to mouse liver and biliary dysfunction. The DMH administration invariably led to increase in the liver microsomal proteins of molecular weight of about 29 (ERp29) and 53 kDa (ERp53) and decrease in the protein of molecular weight of 36 kDa (ERp36) thereby suggesting the interference of DMH and its metabolites with normal protein biosynthesis and folding, in the reticular membranes of the liver cells thus developing ER stress. Histological studies show necrosis, large sized hepatocytes with increased N:C ratio, aberrant mitotic figures and prominent nucleoli in the liver of DMH treated mice. In animals fed 5% Triphala in diet (w/w) during DMH administration, there was significant decrease in the above changes in the liver suggesting the suppression of DMH induced ER stress in liver. Triphala significantly (P < 0.05) decreased lipid peroxidation and also the activity of lactate dehydrogenase (LDH) in mouse liver. It simultaneously increased the level of reduced glutathione (GSH) and the activity of glutathione-S-transferase (GST) thereby suggesting that it prevents peroxidative damage and also diverts the active metabolites (electrophiles) of DMH from their interactions with critical cellular bio-molecules which could be responsible for its protective action against DMH.
