In the past, we showed that large electrolytic lesions of the dorsomedial hypothalamus (DMH) promoted hypothermia in cold-exposed restrained rats, but attenuated hypothermia in rats challenged with a high dose of bacterial lipopolysaccharide (LPS) in a thermogradient apparatus. The goal of this study was to identify the thermoeffector mechanisms and DMH representation of the two phenomena and, hence, understand how the same lesion could produce two opposite effects on body temperature. We found that the permissive effect of large electrolytic DMH lesions on cold-induced hypothermia was due to suppressed thermogenesis...

Neuroblastoma amplified sequence (NBAS) gene mutation or infantile liver failure syndrome type 2 (ILFS type 2) is an extremely rare disease characterized by episodic liver failure precipitated by intercurrent febrile illness, and liver function recovering completely. Here, we report a 4-year-old girl with recurrent hepatitis. A diagnosis of ILFS type 2 was made based on NBAS mutation gene found by whole-exome sequencing. Our case provides a new insight toward considering NBAS mutation as a part of the differential diagnoses of any infant presenting with recurrent liver failure or hepatitis...

Cytomegalovirus (CMV) infection is a well-recognised complication of immunodeficiency, although the burden of CMV disease in immunocompetent adults is still unknown. We present the case of a 54-year-old male patient admitted due to severe diarrhoea, epigastric pain and fever. Initial diagnostic workup revealed pericardial and pleural effusion, enlarged abdominal lymph nodes and mild elevation of liver enzymes. CMV serology was IgM positive, and upper endoscopy revealed proximal enteritis. Histology and immunohistochemistry of duodenal samples confirmed CMV disease...

OBJECTIVE: Restless legs syndrome (RLS) is a common sensory motor disorder. RLS an urge to move the extremities that may be accompanied by dysesthesias, and significantly affects quality of life of affected patients. The frequency of RLS is higher in different systemic inflammatory diseases. Familial Mediterranean fever (FMF) is an inherited inflammatory disease characterized by attacks of polyserositis, arthritis, and fever. The prevalence of RLS in patients with FMF is unknown. This study aimed to evaluate the prevalence rate of RLS in a sample of patients with FMF and compare this prevalence with that of a matched normal population...

Zoledronic acid is an established agent used in the management of metastatic bone disease. The administration of zoledronic acid improves overall survival (OS) of lung cancer patients with bone metastases receiving chemotherapy. However, it is currently unknown whether zoledronic acid-induced fever is associated with OS. The purpose of this study was to examine the association between zoledronic acid-induced fever and prognosis in lung cancer patients with bone metastases. We retrospectively analyzed 98 lung cancer patients with bone metastases who had received zoledronic acid...

Myocardial Abscess (MA) is a rare life threatening condition mostly occurring secondary to underlying infective endocarditis. But it can also be found secondary to septicemia with some unknown focus of sepsis in the body. Development of MA as a consequence of left ventricular aneurysm (LVA) secondary to myocardial infarction is very rare. We report the case of 56 year old male, who presented with high grade fever and leukocytosis. On detailed evaluation, he was found to have a myocardial abscess with underlying LVA...

Steve Turner
Asthma is a common condition, which is associated with atopy and allergic conditions including hay fever, eczema, and food allergies. Asthma and atopy are both complex conditions where genetic and environmental factors are implicated in causation. Interactions between genetic and environmental factors, likely via epigenetic mechanisms, are widely thought to be important in determining the risk for developing asthma and atopy. The nature of the relationship between asthma and atopy is unclear and the answer to the question "does atopy cause asthma?" remains unknown...

FDG is a tracer for visualizing glucose metabolism. PET/CT using FDG is widely used for the diagnosis of cancer, because glycolysis is elevated in cancer cells. Similarly, active inflammatory tissue also exhibits elevated glucose metabolism because of glycolysis in activated macrophages and proliferating fibroblasts. Elevated FDG uptake by active inflammatory tissues, such as those affected by arthritis, vasculitis, lymphadenitis, and chondritis, has enabled the diagnosis of inflammatory diseases using FDG-PET/CT...

Antineutrophil cytoplasmic antibody (ANCA) has been known to cause pauci-immune crescentic glomerulonephritis. In addition, several reports described membranous glomerulonephritis (MN) concurrent with ANCA-associated glomerulonephritis. Because the two glomerular diseases simultaneously appear in an ANCA-positive patient, the mechanisms whereby ANCA causes the two different glomerular diseases remain ambiguous. Herein, we report a case of 19-year-old man who presented with hematuria, pre-nephrotic proteinuria, and high titer of myeloperoxidase (MPO)-ANCA...

Hantavirus infection is an acute zoonosis that clinically manifests in two primary forms, hemorrhagic fever with renal syndrome (HFRS) and hantavirus pulmonary syndrome (HPS). HFRS is endemic in Europe and Russia, where the mild form of the disease is prevalent in the Tatarstan region. HPS is endemic in Argentina, as well as other countries of North and South American. HFRS and HPS are usually acquired via the upper respiratory tract by inhalation of virus-contaminated aerosol. Although the pathogenesis of HFRS and HPS remains largely unknown, postmortem tissue studies have identified endothelial cells as the primary target of infection...

Encephalitis is a severe neurological syndrome associated with high morbidity and mortality as well as long-term neurological sequelae. Despite being an important public health problem, very few extensive population-based studies were conducted so far in the world and none in Central Europe. Altogether 114 consecutive patients meeting the initial criteria for encephalitis were enrolled at the Warsaw Hospital for Infectious Diseases between June 2012 and July 2015. Eighteen patients were secondarily excluded from the analysis due to incomplete data or noinfectious cause...

A 59-year-old woman suffered from fever and upper abdominal pain. The computed tomography (CT) scan revealed a liver lesion. Conventional imaging techniques (CT, magnetic resonance imaging, contrast-enhanced ultrasonography) did not allow for a consistent diagnosis. Fine needle biopsy of the liver lesion was performed. Histologically, fibrotic inflammation was found and an inflammatory pseudotumor (IPT) diagnosed. Despite treatment with steroids and antibiotics, the size of the IPT increased; thus, surgical resection was necessary...

BACKGROUND: Based on the traditional application of traditional Chinese Medicines (TCMs), Ephedra Herba (EH) is used to cure cold fever by inducing sweating, whereas Ephedra Radix (ER) is used to treat hyperhidrosis. Although they come from the same plant, Ephedra sinica Stapf, but have play opposing roles in clinical applications. EH is known to contain ephedrine alkaloids, which is the driver of the physiological changes in sweating, heart rate and blood pressure. However, the active pharmacological ingredients (APIs) of ER and the mechanisms by which it restricts sweating remain unknown...
