A needle in the haystack: An unusual case presentation of ganglioneuroblastoma at a tertiary care center in Coastal Karnataka.

Key Clinical Message: This case report highlights the importance of recognizing and accurately diagnosing ganglioneuroblastoma, an uncommon variant of neuroblastic tumors in children. Ganglioneuroblastomas have diverse clinical and morphological presentations, and histopathological examination is paramount in guiding treatment decisions, especially in cases with ambiguous symptoms. Early detection is crucial, as the prognosis varies significantly based on the subtype and the presence of metastatic disease. Clinicians should maintain a high index of suspicion and utilize radiological examinations to promptly identify and treat these tumors. Abstract: Children are frequently affected by neuroblastic tumors, which grow from the sympathoadrenal lineage of the neural crest during its development. However, intermixed ganglioneuroblastomas are far less common within the same tumor spectrum, the diagnosis of which could become challenging amidst an unusual presentation. In our case report, we present a 4-year-old boy who had complaints of fever and difficulty in walking, with a supra-renal mass on ultrasound, which was diagnosed as ganglioneuroblastoma-intermixed type on histopathological examination. This report aims to contribute to the understanding of the diverse clinical and morphological spectrum of ganglioneuroblastomas and the importance of multidisciplinary collaboration and histopathological examination to enhance decision-making in such ambiguous scenarios.

Acceptability of human papillomavirus vaccination among medical students in Mangalore, India.

BACKGROUND: The highly prevalent cervical cancer can be prevented through a vaccine. However, the uptake of the Human Papillomavirus vaccine in the general population continues to be low. Medical students, as healthcare providers in the future, would be influential in affecting the community's views and thereby the uptake of the Human Papillomavirus vaccine. Hence, there is a need to promote the right attitude for prompt implementation of this vaccine among medical students. None of the studies in India have so far documented the proportion of vaccinated population among medical students or an intervention strategy to eliminate the barriers to Human Papillomavirus vaccine. AIMS AND OBJECTIVES: To determine the proportion of vaccinated medical students and the barriers against HPV vaccination among non-vaccinated participants; and to test the efficacy of an information session on the barrier. METHODOLOGY: Data on barriers against the Human Papillomavirus vaccination was collected through a questionnaire-based survey. The barriers were reassessed after an intervention in the form of training session using audio-visual aids. RESULTS: Out of the 263 participants, 46 (18%) had never heard of the vaccine against Human Papillomavirus and only 54 (21%) were vaccinated. Participants thought it was not essential to get vaccinated as they were not sexually active (28%). Lack of information about the vaccine (28%), its access (24%), and high cost (27%) were the other barriers. Following the information session, 59% of the previously non-vaccinated participants responded that they would get vaccinated while 34% were considering getting vaccinated. The most common reason for rejection of the vaccine post- intervention was high cost of the vaccine. CONCLUSION: Vaccine uptake is very low among medical students and amenable barriers exist against the vaccine. Urgent intervention in the form of information session is recommended targeted at the medical students, to eliminate the barriers of Human Papillomavirus vaccination.

Evaluation of p53 protein expression in Barrett esophagus.

BACKGROUND: Loss of heterozygosity of p53 along with aneuploidy is deemed to be the early molecular steps in Barrett metaplasia-dysplasia-adenocarcinoma sequence. Objective biomarkers need to be used along with microscopy for risk stratification to predict the progression of Barrett esophagus (BE) to carcinoma. AIM: This study aims to study p53 protein expression in dysplasia and correlate the same with morphology in BE. MATERIALS AND METHODS: A time-bound study was conducted from January 2011 to June 2015. All esophageal biopsies showing histological evidence of columnar epithelium with the presence of goblet cells were included. The cases which showed dysplasia were graded on hematoxylin and eosin stain. Evaluation of p53 immunohistochemistry staining was done on all the cases of BE. Dysplasia was correlated with the expression of p53 using Chi-square value (χ2) and Fischer's exact test wherever appropriate. P < 0.05 was considered to be statistically significant. RESULTS: Of 829 esophageal biopsies received, 119 were endoscopically suspected to be BE, of which 85 cases were confirmed on microscopy. In our study, there were 75 cases negative for dysplasia (88.2%), 8 with low-grade dysplasia (LGD) (9.4%), and two with high-grade dysplasia (HGD) (2.4%). Three cases of BE had associated adenocarcinoma. Immunostaining with p53 done on all the 85 cases showed positive staining in all cases with LGD, one with HGD and two with adenocarcinoma. In the present study, immunostaining with p53 showed 90% sensitivity, 89.3% specificity, positive predictive value of 52.9%, and negative predictive value of 98.5%. CONCLUSION: The technical simplicity, easy availability, and comparatively lower cost enhance the role of p53 as a biomarker in risk stratification for patients with BE.

Thalassaemia Trait with Gaucher Disease: A Diagnostic Dilemma.

Gaucher Disease is an autosomal recessive disease caused by the accumulation of glucocerebrosidase due to deficiency in lysosomal glucocerebrosidase. Thalassaemia trait is asymptomatic and is usually an incidental diagnosis. Both thalassaemia and Gaucher disease can have similar haematologic manifestations and hence, their coexistence causes diagnostic dilemma. Our patient presented at one-and-a-half years with weakness, pallor, failure to thrive and massive hepatosplenomegaly. Clinical examination and history pointed to a lipid storage disease. Peripheral smear revealed microcytic hypochromic cells and nucleated red cells with haemolytic blood picture. Thalassaemia trait was indicated on haemoglobin variant analysis using High Performance Liquid Chromatography. Liver biopsy, bone marrow aspirate and therapeutic splenectomy revealed Gaucher-like cells. Type 1 Gaucher disease can be clinically asymptomatic as well as present with massive liver and spleen enlargement and involvement of bone marrow. Anaemia, splenomegaly and thrombocytopenia are the usual presentations at diagnosis, similar to the haemoglobinopathies. Gaucher-like cells with normal beta-glucocerebrosidase (pseudo-Gaucher cells) are seen in thalassaemia, leukaemia, mycobacterial infections and myeloma. Gaucher disease coexisting with thalassaemia trait is uncommon. We report the occurrence of thalassaemia trait and Gaucher disease in a child, which resulted in confusion regarding the haematological diagnosis. This report highlights the necessity of independent establishment of the diagnosis in every patient so that appropriate management decisions are taken.
