the reversed halo sign (rhs) may sometimes be seen in patients with cryptogenic organizing pneumonia (cop), but is rarely associated with other diseases. herein, we present a case of a 21-year-old woman with chronic eosinophilic pneumonia, with high resolution computed tomography (hrct) finding of rhs. this is an unusual and rare presentation of chronic eosinophilic pneumonia.

Acute cholecystitis can arise in two distinct patient populations: (1) the relatively healthy ambulatory patient who develops acute inflammation of the gallbladder as a result of gallstones and (2) the critically ill, hospitalized patient who may or may not have gallstones. For most patients with acute calculous cholecystitis, surgical removal of the gallbladder is the preferred treatment optio...

The objective was to develop a score, to stratify patients with acute cholecystitis into high, intermediate, or low probability of gangrenous cholecystitis. The probability of gangrenous cholecystitis (score) was derived from a logistic regression of a clinical and pathological review of 245 patients undergoing urgent cholecystectomy. Sixty-eight patients had gangrenous inflammation, 132 acute,...

Acute cholecystitis is a major health problem. There are multiple etiologies to be considered and early recognition of the condition is important to optimize management and outcome. We report the first case in the medical literature of symptomatic acute cholecystitis triggered by ceftriaxone-associated gallbladder sludge formation and, importantly, solid ceftriaxone gallstone formation in an ad...

Emphysematous cholecystitis is a rare, but life-threatening, form of acute cholecystitis caused by gas-forming organisms in the gallbladder. A 73-year-old male patient with type 2 diabetes mellitus complicated with neuropathy associated with schizophrenia was admitted to Okayama University Hospital, Okayama, Japan, because of a high fever and general malaise. On the fourth hospital day, despite...

OBJECTIVE The aim of this study is to investigate the relationship between procalcitonin (PCT) level and the severity of acute cholecystitis. MATERIALS AND METHODS This study included 200 patients diagnosed with acute cholecystitis. To diagnose and assess the severity of acute cholecystitis; physical examination and abdominal ultrasound findings were evaluated and blood samples were taken to ...

BACKGROUND Acute cholecystitis is a common diagnosis and surgery is the standard of care for young and fit patients. However, due to high risk of postoperative morbidity and mortality, surgical management of critically ill patients remains a controversy. It is not clear, whether the increased risk of perioperative complications associated with the management of critically ill patients with acut...

Introduction: It is well known that acute cholecystitis can sometimes mimick coronary ischemia with similar pattern of chest pain and ST segment changes and T-wave inversions in ECG. However, dynamic ECG changes which are highly suggestive of coronary ischemia, in a patient of acute calculous cholecystitis is a rare phenomenon. A normal coronary angiogram established that the peculiar ECG chang...

Base excision repair (BER) pathway is one of the repair systems that have an impact on the radiotherapy and chemotherapy for the cancer patients. The molecular pathogenesis of gallbladder cancer is not known extensively. In the present study we investigated whether the expression of AP endonuclease 1 (APE1) and DNA polymerase β (DNA pol β), key enzymes of BER pathway has any clinical ...

abstract acute inflammation of the gallbladder can occur without gallstones. acalculous cholecystitis typically develops in critically ill patients in the intensive care unit. patients on parenteral nutrition, with extensive burns, sepsis, major operations, multiple organ trauma or prolonged illness with multiple organ system failure are at risk for developing acalculous cholecystitis. the asso...
