Imaging of gallstones and complications.

Gallbladder pathologies caused by gallstones are commonly encountered in clinical practice, making accurate diagnosis critical for effective patient management. Radiologists play a key role in differentiating these conditions through imaging interpretation, ensuring that appropriate treatment is initiated. The imaging features of gallstone associated diseases are classified into various categories, such as inflammatory conditions, benign lesions, malignant tumors, and associated complications.

Comparative assessment of radiation therapy-induced vasculitis using [F]FDG-PET/CT in patients with non-small cell lung cancer treated with proton versus photon radiotherapy.

Purpose: To assess radiation therapy (RT)-induced vasculitis in patients with non-small cell lung cancer (NSCLC) by examining changes in the uptake of F-fluoro-D-deoxyglucose ([F]FDG) by positron emission tomography/computed tomography (PET/CT) images of the ascending aorta (AA), descending aorta (DA), and aortic arch (AoA) before and after proton and photon RT.

Method: Thirty-five consecutive locally advanced NSCLC patients were definitively treated with proton (n = 27) or photon (n = 8) RT and concurrent chemotherapy. The patients were prospectively enrolled to undergo [F]FDG-PET/CT imaging before and 3 months after RT.

The Catastrophic Effects of Psychogenic Polydipsia: A Case Report.

Patients with hyponatremia are at risk of severe complications including seizures, coma, and death. Psychiatric patients are particularly susceptible to death from hyponatremia due to the association between psychiatric conditions and psychogenic polydipsia, characterized by water intoxication. We report a case of a schizophrenic patient who presented with altered mental status, leading to a differential diagnosis narrowed through clinical investigations to include hypovolemic hyponatremia, syndrome of inappropriate antidiuretic hormone secretion (SIADH), and psychogenic polydipsia.

Osteomyelitis of the Clivus Secondary to Mucormycosis.

Osteomyelitis of the clivus secondary to mucormycosis is a rare infection of the clivus bone due to infiltration by fungi of the genus Immunocompromised patients and/or those with diabetes mellitus are most at risk of developing this disease. Here, we present the case of a 63-year-old male patient with findings of gas within the clivus on computed tomography angiography. Diagnosis of mucormycosis osteomyelitis was confirmed after endoscopic biopsy and histopathologic examination.

Negative Splenic Angiography in Blunt Trauma: Does Embolization Affect Splenic Salvage?

Angioembolization in blunt splenic trauma is used to maximize splenic preservation. Superiority of prophylactic embolization over expectant management in patients with a negative splenic angiography (SA) is debated. We hypothesized that embolization in negative SA would be associated with splenic salvage.

A preliminary report on pain thresholds in bulimia nervosa during a bulimic episode.

Subjects with bulimia nervosa (BN) have been shown to exhibit abnormal satiety responses. Short-term satiety is largely mediated by afferent vagal activity. Activation of afferent vagal fibers has also been found to stimulate a descending pain inhibitory pathway that leads to elevation in somatosensory pain thresholds.

Evaluation of the USDA Protocol for Detection of Listeria monocytogenes.

This study compared the recovery of Listeria monocytogenes from Fraser broth incubated 26 h versus 48 h. L. monocytogenes was isolated from 60 of 1,088 samples analyzed.

A Survey of 18 Dry Dairy Product Processing Plant Environments for Salmonella , Listeria and Yersinia.

An environmental microbiological surveillance program was conducted throughout the dry milk industry in cooperation with the American Dairy Products Institute (ADPI). The purpose of the survey was to determine the frequency and location of certain pathogenic microorganisms in dry milk and whey processing plant environments. A total of 402 samples were collected from 18 plants by each respective plant's personnel.
