Sepsis represents a clinical syndrome following an infection and it is characterized by classical signs of systemic inflammatory response syndrome (SIRS): fever or ipothermia, tachycardia, tachipnea, leucocytosis or leucopenia. There may also be symptoms related to a specific infection such as a cough in pneumonia or burning with urination in a kidney infection, and abdominal pain in an intraabdominal sepsis. Common locations for the primary infection include lungs, brain, urinary tract, skin and soft tissues, and mainly abdominal organs...

The nociceptin system comprises the nociceptin receptor (NOP) and the ligand nociceptin/orphanin FQ (N/OFQ) that binds to the receptor. The archetypal role of the system is in pain processing but the NOP receptor is also expressed on immune cells. Activation of the NOP receptor is known to modulate inflammatory responses, such as mast-cell degranulation, neutrophil rolling, vasodilation, increased vascular permeability, adhesion molecule regulation and leucocyte recruitment. As there is a loss of regulation of inflammatory responses during sepsis, the nociceptin system could be a target for therapies aimed at modulating sepsis...

Bacterial infections are common in patients with nephrotic syndrome, including peritonitis, sepsis, meningitis, urinary tract infection, and cellulitis. An 8-year-old boy presented with colicky abdominal pain, vomiting, swollen and painful erythematous lesions around the umbilicus and in anterior surface of left thigh (cellulitis), mild generalized edema, and ascites. The microorganism isolated from peritoneal fluid and blood cultures was Pneumococcus. Association of pneumococcal sepsis, peritonitis, and cellulitis has been rarely reported in nephrotic syndrome...

OBJECTIVE: To present an atypical manifestation in a patient with pheochromocytoma. CLINICAL PRESENTATION AND INTERVENTION: A 48-year-old man presented with chest pain, fever and leukocytosis. Elevated cardiac biomarkers and diffuse ST-T abnormalities on electrocardiography suggested myocardial infarction. However, coronary angiography showed normal coronary arteries. Abdominal computed tomography revealed a left adrenal tumor of 6.7 × 6.8 cm. Paroxysmal fluctuation of blood pressure raised the suspicion of pheochromocytoma, which was further supported by elevated urine catecholamine levels...

Acute mesenteric ischemia is commonly seen in old patients. This study was undertaken to show that mesenteric ischemia might be seen in individuals under 40 years of age and that its diagnosis is challenging. Twenty-six patients with acute mesenteric ischemia under the age of 40 were studied. The main symptom on admission was abdominal pain. Symptom duration varied between 12 h and 5 days. The medical history of the patients revealed that 9 had no previous diseases. Other 17 had predisposing factors in the first evaluation...

Patients with burns less than 40% TBSA do not have catabolism unless sepsis develops. Those with burns more than 40% TBSA always experience catabolism, which causes metabolic derangements that persist for at least 1 year after the injury in most body tissues. The accomplishments of the past decade have placed us in the midst of an exciting paradigm shift from what used to be a primary concern (ie, mortality) to areas that are more likely to enhance the quality of life of burn survivors. Modulating postburn hypermetabolism for the burned patient is of overwhelming importance in both the immediate care stage and the rehabilitative stage...

The brain and the immune system are the two major adaptive systems of the body. During an immune response the brain and the immune system "talk to each other" and this process is essential for maintaining homeostasis. Two major pathway systems are involved in this cross-talk: the hypothalamic-pituitary-adrenal (HPA) axis and the sympathetic nervous system (SNS). This overview focuses on the role of SNS in neuroimmune interactions, an area that has received much less attention than the role of HPA axis...
