The Severity of Interstitial Inflammation in the Renal Parenchyma of Albino Rats Is Subjected to the Dose of Heavy Metals.

Aim This study aimed to determine the relationship between irreversible morphological changes in the renal interstitium and the duration of exposure to heavy metals such as copper in albino rats. Materials and methods An experimental research design was used to conduct this study from November 2019 to May 2020. All experiments were performed in the Department of Pathology of the Services Institute of Medical Sciences, University of Health Sciences (UHS) (animal house), Lahore, Pakistan.

Fine-Needle Aspiration Cytology in the Diagnosis of Pancreatic Neuroendocrine Tumors: A Single-Center Experience of 25 Cases.

Objective: Pancreatic neuroendocrine tumors (Pan NETs) are rare but are being increasingly diagnosed. The objective of this retrospective study was to share our experience of fine-needle aspiration (FNA), including endoscopic ultrasound-guided FNA with rapid on-site evaluation (ROSE), with the use of immunohistochemical (IHC) markers in the diagnosis of Pan NET.

Study Design: A total of 25 cases of Pan NET diagnosed on pancreatic FNA between 2008 and 2013 were identified from our hospital database.

Onsite cytopathology evaluation and ancillary studies beneficial in EUS-FNA of pancreatic, mediastinal, intra-abdominal, and submucosal lesions.

Introduction: Endoscopic ultrasound-guided fine needle aspiration cytology (EUS-FNA) is considered to be a minimally invasive and safe technique, with low complication rates, for obtaining tissue samples from pancreatic lesions, and mediastinal and intra-abdominal nodes. We retrospectively reviewed the diagnostic accuracy of this method at a tertiary care hospital in Pakistan.

Methods: The medical records of 393 consecutive patients referred to the gastroenterology service from August 2008 to September 2013 were reviewed in this retrospective study.

Pelvic-peritoneal tuberculosis mimicking ovarian cancer.

Pelvic-peritoneal tuberculosis is a common extrapulmonary site in young females mimicking an advanced ovarian malignancy. We present 2 cases with the classical triad of advanced-stage ovarian carcinoma-ascites, abdominopelvic masses and elevated serum CA-125 levels. Laparoscopic examination revealed peritoneal nodules which on biopsy showed granulomatous inflammation and no malignant cells.
