During acute cystitis, uropathogenic Escherichia coli (UPEC) induce bladder epithelial cell exfoliation, which eliminates infected cells and promotes UPEC dissemination. Dhakal and Mulvey (2012) uncover the mechanism that induces this exfoliation and reintroduce the pore-forming toxin, hemolysin, as an effector that surprisingly targets multiple host pathways to facilitate infection.

ABSTRACT: Oculogyric crisis is a neurologic adverse event characterized by bilateral dystonic, usually upward, conjugate eye deviations. Cefixime is a third-generation cephalosporin and is widely used in clinical practice in childhood. Confusion, encephalopathy, coma, myoclonus, nonconvulsive status epilepticus, and seizures have been described with the use of cephalosporins. We presented ...

Five 25-yr-old crocodiles (Crocodylus johnstoni and Crocodylus porosus) were diagnosed with Aeromonas hydrophila-associated septicemia accelerated by improper thermoregulation. At necropsy, pulmonary congestion and pleural effusion were the main lesions in the thorax. Necrotizing enteritis, intestinal hemorrhage, fibrinous serositis, hepatitis, and pancreatitis were observed in the abdominal cavities of all five ...

Helicobacter pylori infections are closely associated with peptic ulcers, gastric malignancy and iron deficiency anemia. Iron is essential for almost all living organisms and the investigation of iron uptake and trafficking system is thus important to understand the pathological roles of H. pylori. Up to now, the iron trafficking system ...

Development of the pathologies associated with Helicobacter pylori infection, most seriously gastric adenocarcinoma, are a consequence of chronic inflammation, which both host and pathogen go to some lengths to minimize. Recently, we presented evidence that H. pylori can suppress the development of inflammation in its immediate microenvironment in the gastric ...

Background:Methotrexate is a mainstay of treatment for autoimmune conditions such as rheumatoid arthritis and psoriasis. Methotrexate has numerous potential side effects and, in rare circumstances, can lead to cutaneous ulceration. Methotrexate can cause skin ulceration, and stopping this medication can lead to complete healing of the ulcerated lesion.Observations:A 67-year-old man ...

Moisture-associated skin damage (MASD) occurs when excessive moisture in urine, stool, and wound exudate leads to inflammation of the skin, with or without erosion or secondary cutaneous infection.

BACKGROUND: Despite recent advances and better understanding of the etiology and the pathogenesis of gastrointestinal ulcer diseases, e.g., duodenal ulcer, the molecular events leading to ulcer development, delayed healing, and recurrence remain poorly elucidated. AIMS: After we found that duodenal ulcers did not heal despite increased levels of vascular endothelial ...

Urinary diversion is indicated for the management of the neurogenic bladder. However, there is a risk for developing pyocystitis in this type of patients. We present a case of young female who presented with a history of frequent urinary tract infection (UTI) post urinary diversion for neurogenic bladder. Ever since ...

The opportunistic fungal pathogen Aspergillus fumigatus adapts to iron limitation by upregulation of iron uptake mechanisms including siderophore biosynthesis and downregulation of iron-consuming pathways to spare iron. These metabolic changes depend mainly on the transcription factor HapX. Consistent with the crucial role of iron in pathophysiology, genetic inactivation of either ...

It is important in treatment of gastric ulcers to not only prevent further ulcer formation but also enhance ulcer healing. When cells are exposed to gastric irritants, expression of heat shock proteins (HSPs) is induced, making the cells resistant to the irritants. We recently reported direct evidence that HSPs, especially ...

Reactive arthritis belongs to the group of arthritidies known as the spondyloarthritides. There are two main types of reactive arthritis: post-venereal and post-enteric. Chlamydia trachomatis is felt to be the most common cause of reactive arthritis, in general. Until recently, even the terminology for the condition itself was unclear as ...

Hemotrophic mycoplasmas (HM) are uncultivable bacteria found on and in the red blood cells (RBCs). The main clinical sign of HM infections is the hemolytic anemia. However, anemia-inducing pathogenesis has not been totally clarified. In this work we used the splenectomized pig as animal model and Mycoplasma suis as a ...

Ulceration corresponds to tissue loss, breaching the muscularis mucosae. When ulcers develop in the acid-peptic environment of the gastroduodenum, they are traditionally called peptic ulcer (PUD). Ulcers never develop spontaneously in a healthy gastroduodenal mucosa. Ulceration is the ultimate consequence of a disequilibrium between aggressive injurious factors and defensive mucosa-protective ...

Helicobacter pylori induces an inflammatory immune response in the gastric mucosa. The degree of gastric mucosal inflammation and its topographic distribution are key factors in the diversity of H. pylori-related complications. Here we summarize substantial evidence reported in the literature concerning the impact of H. pylori density on gastric inflammation, ...
