RESUMEN
INTRODUCTION: Functional Dyspepsia (FD) is one of the most common causes of gastrointestinal symptoms aetiology of which is poorly understood. AIM: To study duodenal histomorphological features and their relationship with Helicobacter pylori (H Pylori) infection in patients of FD. MATERIALS AND METHODS: This case control study included 50 cases of FD patients selected according to Rome III criteria and 30 age and sex matched controls. These were subjected to oesophago-gastro-duodenoscopy, rapid urease test for detection of H. pylori on gastric antral biopsy and duodenal biopsy from second part of duodenum for histopathological evaluation by light microscopy. Ten antral urease positive cases of FD with highest Intraepithelial Lymphocyte Count (IEL) were subjected to Immunohistochemistry (IHC). RESULTS: Duodenal inflammation was an invariable feature noted in FD. Morphological spectrum consisted of increased IEL in 72%, increased duodenal eosinophils in 92%, presence of focal villous atrophy in 16%, lymphoid aggregates, colonic metaplasia, and duodenal H. pylori infection in 4% each. Gastric H. pylori positivity was noted in 48% cases of FD. Increased duodenal IEL count and duodenal eosinophilia was noted in 75%, 87.5% such cases. Same was noted respectively, with 61.5% and 95.15% cases with gastric H. pylori negativity. In cases of FD, duodenal IEL and eosinophil count in lamina propria showed statistically significant rise when compared with control and had positive correlation with gastric H pylori infection. On IHC, increased expression of CD 8 was noted in duodenal IEL and lymphocytes in lamina propria as compared to CD4. CONCLUSION: Our study provided some insight in pathogenesis of FD and role of H. pylori in its aetiology.
RESUMEN
Primary malignancies of female urethra are infrequent, constituting a fraction of less than 1% of genitourinary malignancies. Primary clear-cell adenocarcinoma of the urethra, is even rarer, that histomorphologically resembles clear-cell carcinoma of the female genital tract, occurs predominantly in women and is associated with a relatively poor prognosis. The histogenesis of this rare urethral neoplasm has not been completely determined. Various hypotheses concerning the origin have been postulated, including (1) diverticular origin (2) mullerian origin (3), glandular differentiation of urothelium or urothelial carcinoma. Here, we report a case of 67-year-old female with obstructive urinary symptoms and pain in abdomen, diagnosed with adenocarcinoma of urethra. Immunohistochemistry (IHC) workup of the tumour was done to find the origin of the tumour.
RESUMEN
Allergic fungal sinusitis (AFS) is a distinct clinicopathological entity. It occurs in immunocompetent individuals with history of atopy, increased IgE levels and peripheral eosinophilia and causes noninvasive pansinusitis. It is histologically characterised by the presence of 'allergic mucin' with clusters of eosinophils, charcot - Leyden crystals and scattered fungal hyphae. AFS is an immunological reaction to fungal deposits. As AFS is noninvasive, fungal hyphae can be demonstrated in nasal secretions on cytology. Etiological agent of AFS is Aspergillus or pigmented dematiaceous family. Special stains are helpful for identification. We came across three cases of age group ranging from 26 to 60-year of recurrent rhinitis with nasal discharge. The nasal secretions were collected by nasal swabs onto the glass slide and stained with Giemsa and silver stains. Smears revealed fungal hyphae amidst inflammatory cells with occasional Charcot-Leyden crystals. Nasal secretion cytology plays an important role in diagnosis and can be used for preoperative as well as intraoperative diagnosis of AFS and can be used as an additional diagnostic tool.
