Background: Bacille calmette–guerin (BCG) vaccine containing live-attenuated Mycobacterium bovis was first used in humans to prevent tuberculosis in 1921. It is a safe vaccine. However, there can be minor adverse reactions such as pain, swelling, and redness at local injection site. The lesser known severe adverse reactions such as lymphadenitis, BCG osteitis, and disseminated BCG infection can be present after BCG vaccination. Aims and Objectives: The aim of the study was to report the cases of BCG lymphadenitis diagnosed by fine needle aspiration cytology (FNAC) after BCG vaccination in infants and children. Materials and Methods: All the infants and children (1 month–2 years) who presented with regional lymphadenopathy for FNAC after BCG vaccination were included in the study. Results: Total 21 patients with BCG lymphadenitis were recruited. In all the cases, the lymphadenitis involved ipsilateral left axillary lymph nodes. In three patient sites of involvement included the left supraclavicular lymph nodes and in other three patients left cervical lymph nodes along with left axillary lymph node. Sixteen patients had suppurative granulomatous lymphadenitis (SGLA) on FNAC and positive for Ziehl–Neelsen (ZN) staining for acid fast bacilli (AFB), while rest nine had non-suppurative granulomatous lymphadenitis (NSGLA) with negative for ZN staining for AFB. Conclusion: Early diagnosis of BCG lymphadenitis can help in proper management. Furthermore, it can prevent unnecessary anti tubercular treatment in children.
Background: Gallbladder carcinoma (GBC) although rare is most frequent malignant neoplasm of biliary tract system and sixth most common malignancy of digestive tract. GBC is more common in females and there are studies which show expression of estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor-2 neu (HER2/neu) in GBC suggesting possible molecules for targeted therapy, but results are inconsistent. Aims and Objectives: The aim of this study was to find out expression of ER, PR, and HER2/neu in GBC in North Indian population and their possible association with clinicopathological features. Materials and Methods: A total 59 resected cases of GBC diagnosed by histopathological examination were included in the study. Expression of ER, PR, and HER2/neu was accessed by immunohistochemistry method and correlated with various clinicopathological features. Results: ER expression was absent in all GBC cases. PR expression was present in only one case. Positive expression of HER2/neu was present in 13 (22%) cases, in which 12 cases were of conventional adenocarcinoma and one case was of papillary adenocarcinoma. Well and moderately differentiated tumor had significantly higher HER2/neu expression as compared to poorly differentiated tumors (P = 0.001). Pre-obese patients had significantly higher HER2/neu expression as compared to non-obese patients (P = 0.008). Conclusion: In our study, there was no expression of estrogen and PR in GBC in North Indian population. Although small in number, there is a subset of patients who overexpress HER2/neu receptor that may benefit from targeted therapy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
