Peripheral squamous odontogenic tumor associated with an impacted mandibular third molar: A case report

Introduction: Squamous odontogenic tumor is a benign but locally infiltrative, epithelial odontogenic tumor. This case report presents a case of a peripheral variant of squamous odontogenic tumor. Case Presentation: A 29-year-old male patient presented with pain in the left posterior mandible region for one month. Radiographic examination revealed an impacted left mandibular third molar with no other abnormalities. Management and Prognosis: The impacted tooth was removed under local anaesthesia. Histopathological examination of the abnormally thick pericoronal tissue, covering the impacted tooth revealed islands of bland squamous epithelium in a background of mature fibrous connective tissue. The prognosis was good with no signs of recurrence after one year of follow- up. Conclusion: Squamous odontogenic tumor should be considered in the differential diagnosis of pericoronal pathoses, although it is rare in this location.

Cellular Schwannoma of Buccal Mucosa: A Rare Histopathological Variant

Introduction: Schwannoma (Neurilemmoma) is a benign neoplasm that develop from schwann cells in the peripheral nerve sheath. It commonly occurs as an encapsulated, slow-growing and generally solitary lesion. Cellular schwannoma is a rare histopathological variant of schwannoma. Case Presentation: Here, we discuss a case of 44-year-old female patient who reported with the chief complaint of swelling in the left upper back cheek region for the past 2 years. Histopathological and immunohistochemical analysis confirmed the diagnosis as cellular schwannoma. Management and prognosis: Surgical excision of the lesion was performed and no recurrence was reported after 1 year of follow up. Conclusion: Cellular schwannoma a rare intraoral benign tumor, needs to be differentiated from other malignant tumor with a careful approach for a prompt diagnosis and proper management of the lesion

Prevalence of Antimicrobial Resistance Among Vibrio spp. Isolated from the Digestive Tract of Cultured Penaeus vannamei

Shrimp digestive tract microflora has been considered important, as it provides several protective and metabolic functions. Misuse of antibiotics could lead to AMR in the gut microbial community, which could be transferred to humans. The present study aimed in determining the prevalence of the digestive tract microbial community and AMR associated with them. A total of 173 isolates were collected and characterised from the digestive tract of 120 shrimps, collected from six different regions of Maharashtra and Gujarat. A total of 144 gram negative isolates comprised predominantly of Vibrio spp were isolated and characterised. Antimicrobial susceptibility pattern of the isolates against 12 different antibiotics was carried out using disk diffusion method. Most of the isolates showed resistant against beta-lactam class of antibiotics and macrolide antibiotics. Among the 144 G negative isolates, 61 (39.5%) isolates were presumptively identified as Vibrio spp, based on their growth on the specific agar plates. Biochemical characterisation of the 61 Vibrio isolates revealed the presence of 31.14% of Vibrio cholerae, 31.14% of V. parahaemolyticus, 19.67% of V. vulnificus, 9.8% of V. harveyi and 8.2% of V. alginolyticus. The antibiogram profile showed that the 40 (74.07%) isolates were resistant to ampicillin, 24 (44.4%) were resistant to cephalothin, 21 (38.8%) were to aztreonam and 17 (31.5%) were resistant against erythromycin. Prevalence of multi-drug resistance was also observed among the bacterial isolates.
