The presence of pan-resistant bacteria worldwide possesses a threat to global health. It is difficult to evaluate the extent of carriage of resistant bacteria in the population. Sewage sampling is a possible way to monitor populations. We evaluated the presence of pan-resistant bacteria in Israeli sewage collected from all over Israel, by modifying the pour plate method for heterotrophic plate count technique using commercial selective agar plates. This method enables convenient and fast sewage sampling and detection...

Severe cutaneous adverse reactions (SCAR) are known for a high morbidity and mortality. They may be life-threatening for the affected patient and difficult to accomplish for the patient's family and the treating physician. Such conditions include not only bullous reactions like toxic epidermal necrolysis (TEN) and Stevens-Johnson syndrome (SJS), but also acute generalized exanthematous pustulosis (AGEP) and drug reaction with eosinophilia and systemic symptoms (DRESS). Since clinical pattern, etiology, prognosis and treatment differ among these severe skin reactions, a clear diagnosis based on a comprehensive clinical examination, skin biopsy, and specific laboratory tests is necessary...

Granulocyte colony-stimulating factor (G-CSF)-producing tumor is one of the rare types of cancer clinically characterized by an elevated fever and white blood cell (WBC) increment. Although G-CSF producing tumors have been reported in several types of cancer including those of the lungs, cervix and bladder, G-CSF producing hepatocellular carcinoma is extremely rare. Here, we report the case of a rapidly growing and poorly differentiated hepatocellular carcinoma producing G-CSF. The patient showed symptoms of continuous high fever, stomach pain and cough, and high serum WBC counts, C-reactive protein (CRP) and G-CSF levels were found in laboratory tests...

Kikuchi-Fujimoto disease (KFD) is a benign cause of self-limiting subacute necrotizing lymphadenitis. KFD is rarely complicated with reactive hemophagocytic lymphohistiocytosis (HLH), and the clinical features of the simultaneous occurrence of these conditions are uncertain. A 30-year-old Japanese man with a persistent fever and sore throat presented to our hospital for treatment. Laboratory analysis showed bicytopenia, and radiological studies showed systemic lymphadenopathy accompanied by splenomegaly. A bone marrow examination showed hemophagocytic macrophages, suggesting HLH...

Human biomonitoring reference values are statistical estimates that indicate the upper margin of background exposure to a given chemical at a given time. Nationally representative human biomonitoring data on 176 chemicals, including several metals and trace elements, are available in Canada from 2007 to 2013 through the Canadian Health Measures Survey (CHMS). In this work, we used a systematic approach based on the reference interval concept proposed by the International Federation of Clinical Chemistry and Laboratory Medicine and the International Union of Pure and Applied Chemistry to derive reference values (RV95s) for metals and trace elements...
