Impact of COVID-19 Pandemic on Pathology Residency Program: An Experience from India.

OBJECTIVE: To study the impact of the COVID-19 pandemic on pathology residents through a questionnaire-based survey. MATERIAL AND METHOD: We designed a Google survey questionnaire with 20-questions and distributed it to the pathology residents across India via e-mail and WhatsApp. All the responses collected were analysed using appropriate statistical methods. RESULTS: We received a total of 81 responses. The majority (n=55, 68.8%) of the residents were aged 26-30 years with a male-female ratio of 1:2.2. Residents reported a significant decrease in classes as compared to pre-covid times. However, most institutions (90%) shifted to the virtual method for various teaching sessions. About 94.7% of the residents felt a fall in the quality of training due to Covid. A significant number of junior residents (76.92%) reported an inability to complete the target thesis enrolment. The residents saw a substantial decrease in the number of peripheral smears, bone marrow, cytology, and histopathology cases compared to pre-Covid times (p value < 0.001 for all). An overwhelming 83.8% of the pathology residents were posted for COVID-19 duties. About 48.8% turned Covid positive. About 77.5% (n=62) of residents felt that the necessary training period would be extended. CONCLUSION: The COVID-19 pandemic has immensely affected the training and teaching of pathology residents in India. Similarly, this pandemic must have affected pathology residents all across the globe. Therefore, institutions can consider offering an extended period of up to one year, depending upon residents' requests.

Peripheral Lymphadenopathy in Children: Cytomorphological Spectrum and Interesting Diagnoses.

OBJECTIVE: Peripheral lymphadenopathy is a common complaint in the pediatric outpatient department. Fine needle aspiration cytology is the first investigation of choice with a high sensitivity for diagnosis but cytology may be challenging in some cases. The study was planned to study the cytomorphological spectrum and discuss a few interesting cases. MATERIAL AND METHOD: 1890 paediatric subjects' up to 12 years of age with significant peripheral lymph node enlargement and an adequate cytology specimen were included in the study. Inadequate aspirates were excluded. RESULTS: The majority of children presented within 4-8 years of age with a male to female ratio of 1.7:1. The anterior cervical group was most commonly affected, followed by the posterior cervical, axillary and inguinal. Reactive lymphadenitis constituted the majority of the diagnoses, followed by Tuberculosis, acute suppurative, BCG-induced lymphadenitis, Kimura disease, Rosai-Dorfmann disease and Kikuchi-Fujimoto disease. Lymphomas and metastatic malignancies were less common, and mainly consisted of Hodgkin lymphoma, non-Hodgkin lymphoma, anaplastic large cell lymphoma, and Langerhans cell histiocytosis. Cytomorphological features of a few challenging and interesting cases have been discussed. CONCLUSION: Non neoplastic causes of lymphadenopathy predominate in the pediatric age group. A definitive diagnosis rests upon a complete clinical, radiological, microbiological, and cyto-histopathological correlation with the use of ancillary techniques wherever necessary.

Association of Anti-tissue Transglutaminase Antibody Titers and Duodenal Biopsy Findings in Pediatric Patients of Celiac Disease.

Aims & Objectives To ascertain the association of serum anti-tissue transglutaminase (anti-tTG) antibody titers with the severity of duodenal mucosal damage on histology andto predict a possible cut-off value of anti-tTG antibody titers for the diagnosis of Celiac disease. Marsh grading greater than two in conjunction with clinical assessment, which may help avert an invasive endoscopic procedure, especially in medically unfit children. Materials & Methods A retrospective study was designed wherein demographic and laboratory data of children aged less than 12 years with raised anti-tTG antibody titers with available histopathology of duodenal biopsies were extracted from the hospital medical records and reviewed. Results A total of 134 children were included in the study, which showed female preponderance. Histopathological changes, characteristic of Celiac disease, were observed in 116 cases; seven among the rest showed evidence of Giardiasis, and 13 could be considered potential Celiac. Of the 116 patients, 1.7% belonged to Marsh grade I, 5.2% grade II and 8.6%, 26.7%, and 57.7% to grade IIIA, IIIB, and IIIC, respectively. A significant association was found between anti-tTG antibody titers and Marsh grading. The cut-off value of anti-tTG antibody titer levels for diagnosing Celiac disease using receiver operating characteristics (ROC) curve in predicting Marsh greater than two at histology was observed to be 84.6 U/ml with sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of 91.7%, 68.4%, 94.2%, and 59%, respectively. Conclusion An anti-tTG antibody titer greater than 10 times the upper limit of normal (≥84 U/ml) is significantly associated with Marsh grade greater than two. Standard stool microscopy may be used as a simple tool in the workup of all children with raised anti-tTG antibody levels to rule out Giardiasis to avert unnecessary endoscopic evaluation for Celiac disease in such cases.
