RESUMEN
Background: Epithelial-mesenchymal transition (EMT) is the heart of invasion. EMT associated with cancer progression and metastasis is known as type III EMT. Beta-catenin, E-cadherin, and MMP9 markers of EMT are routinely employed for diagnostic purposes. Aims: We employed these markers to study EMT by immunohistochemistry (IHC) in gall bladder cancer (GBC) with respect to depth of tumor invasion, clinical outcome, and disease-free survival. Settings and Design: This was a prospective case-control study. Material and Methods: Seventy gall bladders were included (50 GBC and 20 CC). After detailed histology, immunoexpression was studied in terms of percentage and strength of expression. Statistics Analysis Used: Expression was compared between CC and GBC by Student t test and analysis of variance. Kaplan–Meier was used for survival analysis, and the extent of agreement (“Kappa”) was calculated. Results and Conclusions: The age of incidence of GBC was 49.40 (+11.6) years with female predominance (F:M = 4:1). In 88% (44/50) of GBC, the fundus was involved. Moderately differentiated adenocarcinoma was most frequent [54%; 27/50]. Significant downregulation of E-cadherin (P = 0.022) and beta-catenin (P < 0.001) and upregulation in MMP9 (P < 0.001) were seen in GBC with respect to CC with significant association among them. MMP9 expression was significantly associated with higher tumor stage but with chemotherapeutic response. Our results display that epithelial-mesenchymal transition type III plays a role in GBC invasion. MMP9 overexpression and loss of membranous beta-catenin may be considered a marker for poor clinical outcomes and advanced disease.
RESUMEN
Recently, several reports have been pointing to a possible relationship between Helicobacter pylori infection of gastric mucosa and dermatological diseases. Association has been reported for urticaria, rosacea, Sjogrens syndrome and Henoch-Schonlein purpura. It has also been suggested that Helicobacter pylori may be one of the organisms capable of triggering psoriasis. We did Helicobacter pylori serology in 50 clinically typical psoriatic patients presenting to the Department of Dermatology, SMHS Hospital, Srinagar to determine if antibodies to Helicobacter pylori could be found in them. These psoriatic patients were without any known gastrointestinal complaints. An equal number of healthy individuals constituted the control group. The prevalence of Helicobacter pylori sero-positivity in psoriatic patients was significantly higher (P < 0.05) than in control group.
RESUMEN
Thirty patients of pemphigus have been treated with Dexamethasone Cyclophosphamide Pulse (DCP) in our hospital in the past three years. Of these twelve patients are off all treatment and are in complete remission while the rest are in different phases of the treatment and responding quite well to the pulse therapy. Only one case of relapse has been experienced till date.
