Purpose Accurate preoperative localization of parathyroid lesion(s) is crucial for successful surgical management primary hyperparathyroidism (PHPT). This study was conducted to compare the effectiveness ultrasonography (USG) neck, 99m Tc-sestamibi (MIBI) imaging with or without SPECT/CT, and 18 F-fluorocholine (FCH) PET/CT in lesions patients PHPT. Methods Fifty-four consecutive PHPT were included this prospective who underwent using 3 diagnostic modalities followed by surgery. The...

Background and Aim: Hyperglycemia-mediated oxidative stress impedes cell-reparative process like autophagy, which has been implicated in impaired β-cell function T2DM. However, the role of mitophagy (selective mitochondrial autophagy) progression hyperglycemia remains elusive. This study aimed to assess impact increasing severity on mitophagy. Design Methods: A case-control including healthy controls, subjects with prediabetes, newly diagnosed T2DM (NDT2DM) advanced duration (ADT2DM) (n=20...

Gallbladder cancer (GBC) is highly aggressive. Diagnosis of GBC challenging as benign gallbladder lesions can have similar imaging features. We aim to develop and validate a deep learning (DL) model for the automatic detection at abdominal ultrasound (US) compare its diagnostic performance with that radiologists. In this prospective study, multiscale, second-order pooling-based DL classifier was trained (training validation cohorts) using US data patients acquired between August 2019 June...

Background. Potentially lethal cardiac complications can occur in patients with acute organophosphate poisoning (OPP) and may be overlooked. Patients Methods. Thirty-six OPP were studied. Clinical features the nature of compound involved recorded. The QT interval was plotted against heart rate to determine risk for Torsades de Pointes using Fossa nomogram. Echocardiography undertaken 29 patients. Twenty-four-hour Holter monitoring performed on day 1 five Thirteen died. Necropsy hearts...

Acquired dermal macular hyperpigmentation (ADMH) is a hypernym encompassing Riehl's melanosis, lichen planus pigmentosus, and ashy dermatoses that show significant clinicopathological overlap. We sought to describe the dermatoscopic features of ADMH correlate them with histopathological findings.This was prospective observational study performed in two phases. A detailed clinical examination performed, skin biopsies were obtained 51 patients. Two dermatologists blinded dermatopathologist...

Background To explore underlying molecular mechanisms in the pathogenesis of symptomatic sporadic primary hyperparathyroidism (PHPT). Materials and methods Forty-one parathyroid adenomas from patients with PHPT ten normal glands either ( n =3) or euthyroid without during thyroid surgery =7) were analyzed for vitamin D receptor (VDR), calcium-sensing (CASR), cyclin D1 (CD1), hormone (PTH) expressions. The protein expressions assessed semiquantitatively by immunohistochemistry, based on...

Cyclin D1, a G1-S phase regulator, is upregulated in parathyroid adenomas. Since cyclin-dependent kinase (CDK) inhibitors, CDKN2A and CDKN2B, RASSF1A (Ras-association domain family 1, isoform A) are involved arrest act as potential tumor suppressor genes, we aimed to study methylation-mediated inactivation of these genes Gene expressions cyclin D1 (CCND1) regulatory molecules (CDKN2A, CDKN2B RASSF1A) was analysed adenoma tissues (n = 30). DNA promoter methylation regulators were assessed...

The exact mechanism causing decreased expression of the vitamin D receptor (VDR) and calcium-sensing (CASR) genes in parathyroid adenoma is not known, but methylation promoter regions often detected during epigenetic downregulation gene expression. We investigated whether silencing involved VDR CASR. Real-time PCR immunohistochemistry confirmed CASR at transcriptional translational levels. Bisulfite-converted DNA samples from adenomas with control were analyzed for region genes. There was no...
