Fourteen patients with anaphylaxis to pork or beef kidney underwent prick tests to meat and ...

Acute cardiac arrest during pregnancy is a rare but devastating event. Major causes are haemorrhagic, septic or anaphylactic shock, trauma, pulmonary or amniotic fluid embolism, and congenital or acquired cardiac disease. We present a case of massive intrathoracic migration of viscera through a left diaphragmatic hernia in a pregnant multipara, ...

Today it is known that severe burns can be accompanied by the phenomenon of vasoplegic syndrome (VS), which is manifested by persistent and diffuse vasodilation, hypotension and low vascular resistance, resulting in circulatory and respiratory failure. The decrease in systemic vascular resistance observed in VS is associated with excessive production ...

Impressive advances in defining the properties of receptors for the Fc portion of immunoglobulins (FcR) have been made over the past several years. Ligand specificities were systematically analyzed for both human and mouse FcRs that revealed novel receptors for specific IgG subclasses. Expression patterns were redefined using novel specific anti-FcR ...

Acute pancreatitis (AP) is an inflammatory disease in which the regulatory pathways are not clearly elucidated. Activation of interleukin 1β (IL-1β) and immunomodulation via MyD88, the first signaling molecule in the ST2 pathway, seem to be involved. Because IL-33, the ST2 ligand, is an IL-1 family member and acts as ...

The constellation of advanced cardiac life support (ACLS) events, such as gas embolism, local anesthetic overdose, and spinal bradycardia, in the perioperative setting differs from events in the pre-hospital arena. As a result, modification of traditional ACLS protocols allows for more specific etiology-based resuscitation. Perioperative arrests are both uncommon and ...

Hypovolemia is the most common cause of circulatory failure in children and may lead to critical tissue perfusion and eventually multiple-organ failure. Administration of fluids to maintain or restore intravascular volume is a common intervention after hemorrhagic shock occurring during surgical procedures or in patients with trauma. Notwithstanding, there is ...

Symptoms typically start within minutes to one hour after exposure. Diagnosis is based on history, evidence of specific IgE antibodies and skin prick testing ...

Shock as reaction to life-threatening condition needs to be reclassified in a timely and more scientific synopsis. It is not possible or beneficial any longer to avoid a holistic approach in critical illness. Semantics of critical illness has often been unfriendly in the literature and a simplification with the elimination ...

In France, acute life-threatening situations are handled by the French Secours a Personne (assistance to persons) and emergency medical facilities. An unequivocal success, this early management of life-threatening emergency situations relies upon centralized call reception, medical dispatching, and immediate on-site emergency medical care. We describe the different emergency care providers ...

Many insects bite in order to obtain a blood meal and, in the process, inject the victim with saliva that may contain a number of substances, some of which can be immunogenic. The consequences of insect bites include local reactions, immune (allergic) reactions including anaphylaxis, and secondary bacterial infections (e.g. ...

Insect pests are responsible for human suffering and financial losses worldwide. New and environmentally safe insecticides are urgently needed to cope with these serious problems. Resistance to current insecticides has resulted in a resurgence of insect pests, and growing concerns about insecticide toxicity to humans discourage the use of insecticides ...

Diabetic retinopathy (DR) is a complication of diabetes mellitus that can cause blindness. As the prevalence of diabetes increases globally and patients live longer, the cases of DR are increasing. To address the visual disabilities due to DR, screening of all diabetics is suggested for early detection. The rationale and ...

Humans can be incidentally parasitized by third-stage larvae of Anisakis species following the ingestion of raw or undercooked seafood. Acute gastric anisakiasis is one of the most frequently encountered complaints in Korea. However, duodenal anisakiasis with duodenal ulcer had not been reported in Korea, despite the habit of eating raw ...

Th2 cells play an important role in intermittent allergic rhinitis (IAR). Interleukin (IL)-33 stimulates the production of Th2-associated cytokines. IL-33 binds to ST2 receptor which is highly expressed on mast cells and selectively on Th2 cells. IL-33 and ST2 might be involved in the Th2-mediated immune response. We analyzed the ...

   Mastocytosis is a broad term used for a group of disorders characterized by accumulation of mast cells in the skin with or without extracutaneous involvement. The clinical spectrum of the disease varies from only cutaneous lesions to highly aggressive systemic involvement such as mast cell leukemia. Mastocytosis can present ...

Aspirin and non-steroidal anti-inflammatory drugs (ASA/NSAIDs) are common causes of drug hypersensitivity. An oral provocation test is the only definitive diagnostic test. This study assessed the reliability of a flow cytometry-assisted basophil activation test (FAST) as a safe diagnostic method for ASA/NSAID-induced hypersensitivity, as its high sensitivity and specificity have ...

The molecular mechanisms that drive mucosal T helper type 2 (T(H)2) responses against parasitic helminths and allergens remain unclear. In this study, we demonstrate in mice that TFF2 (trefoil factor 2), an epithelial cell-derived repair molecule, is needed for the control of lung injury caused by the hookworm parasite Nippostrongylus ...

Methods. 45 fourth-year medical students were ...

The Food and Drug Administration's Mini-Sentinel pilot program initially aims to conduct active surveillance to refine safety signals that emerge for marketed medical products. A key facet of this surveillance is to develop and understand the validity of algorithms for identifying health outcomes of interest from administrative and claims data. ...

In our region, Anisakis allergy is responsible for 8% of acute urticarial reactions, 25% of which progress to anaphylactic shock. The poor specificity of skin tests and in vitro specific immunoglobulin (Ig) E means that Anisakis allergy is frequently overdiagnosed. We studied the diagnostic value of 2 Anisakis allergens: rAni ...

Specific immunotherapy involves certain drawbacks which could be minimized by the use of appropriate adjuvants, capable of amplifying the right immune response with minimal side effects. In this context, we review different types of immunotherapy vehicles and coadyuvants. We describe previous studies by our group in which we demonstrated the ...

Angioedema is a sudden, transient swelling of well-demarcated areas of the dermis, subcutaneous tissue, mucosa, and submucosal tissues that can occur with or without urticaria. Up to 25% of people in the US will experience an episode of urticaria or angioedema during their lifetime, and many will present to the ...
