Filoviruses, consisting of Ebola virus, Marburg virus and Cuevavirus, cause severe hemorrhagic fevers in humans with high mortality rates up to 90%. Currently, there is no approved vaccine or therapy available for the prevention and treatment of filovirus infection in humans. The recent 2013-2015 West African Ebola epidemic underscores the urgency to develop antiviral therapeutics against these infectious diseases. Our previous study showed that GPCR antagonists, particularly histamine receptor antagonists (antihistamines) inhibit Ebola and Marburg virus entry...

Nausea is a common symptom among patients affected by chronic diseases or undergoing various treatments. Because nausea can result from many origins, there is a large differential diagnosis to explore. Its pathophysiology relies on numerous neurotransmitters, on which 5 types of antiemetic antagonists are effective (NK-1 receptor antagonists, antiserotoninergic, antidopaminergic, antihistaminic and anticholinergic agents). Glucocorticoids and benzodiazepines are also used to treat some types of nausea. Choosing the appropriate antiemetic can improve quality of life and treatment compliance...

BACKGROUND: Several species of jellyfish native to the western Indian Ocean have entered the Mediterranean Sea through the Suez Canal. Since the late 1980s, each summer Rhopilema nomadica forms swarms as long as 100 km in the southeastern Levant and since the millennium aggregations of additional nonnative jellyfish have been sighted. The aim of this study was to evaluate children seen in the emergency department after jellyfish envenomations and to establish patterns of toxicity associated with this organism...

PURPOSE OF REVIEW: This review aims to update the information available on the prevalence, clinical picture, diagnostic methods, and treatment of urticarias induced by external physical stimuli. RECENT FINDINGS: Physical urticarias are present in up to 5% of the general population, and in 10 to 50% of patients with chronic urticaria. Recent investigations have provided evidence that the presence of physical urticaria alone or when comorbid with chronic spontaneous urticaria is associated with a worse prognosis and duration...

The mastocytoses comprise a group of proliferative stem cell disorders defined by the abnormal accumulation of mast cells (MCs) in the skin or other body tissues including the bone marrow, gastrointestinal tract, and liver. Systemic mastocytosis is defined by the presence of one major and one minor criterion or 3 minor criteria delineated by the World Health Organization (WHO). We present the case of a 57-year-old woman with a 10-year history of red-brown pruritic maculopapular lesions on the upper and lower extremities and trunk who was originally diagnosed with cutaneous mastocytosis...

Histamine is a mediator of many physiological processes. It plays an important role in modulating allergy reactions and immune system responses. H1 receptor is a therapeutic target for drugs applied in allergic diseases such as allergic rhinoconjunctivitis, urticarial, or atopic dermatitis. H1-antihistamines display different chemical structures, pharmacokinetics and a potential for drug-drug and drug-food interactions. Drug-food interactions are known to reduce therapeutic effects of the medicine, as well as to induce a potent adverse drug reactions...

BACKGROUND: Antacids, anticholinergic drugs, histamine H2- receptor antagonists and irreversible proton pump inhibitors have been used for the treatment of gastric ulcers. However, prolonged use of these drugs may lead to series of adverse effects such as diarrhea, headache, rash, hypertension, muscular and joint pain. Therefore, there is an urgent need of more effective and safer treatments with fewer side effects. The aim of the present study was to scientifically evaluate the gastroprotective activity of fractions of the hot water extract of Trichosanthes cucumerina Linn (Family: Cucurbitaceae) aerial parts with a view to identifying the fraction with the best gastroprotective activity and the possible mechanism/s by which this fraction exert gastroprotection...

PURPOSE OF REVIEW: Cough is a common and distressing symptom. It has a marked decrement on quality-of-life particularly in the arena of palliative care where coexisting symptoms such as pain may be exacerbated. Whilst local definitive treatment may alleviate coughing it usually requires general measures. The purpose of the review is to assess the current evidence relating to the pharmacological management of cough. RECENT FINDINGS: Key to understanding cough is the realization that most cough is because of a hypersensitivity of the afferent vagus nerve...

BACKGROUND: Allergic rhinitis affects 10 to 40% of the population. It reduces quality of life, school and work performance, and is a frequent reason for office visits in general practice. Medical costs are large but avoidable costs associated with lost work productivity are even larger than those incurred by asthma. New evidence has accumulated since the last revision of the Allergic Rhinitis and its Impact on Asthma - ARIA guidelines in 2010 prompting its update. OBJECTIVE: To provide a targeted update of the ARIA guidelines...

Over the past decades, mass spectrometry technologies have been developed to obtain mass accuracies of one ppm or less. Of the newly developed technologies, quadrupole time-of-flight mass spectrometry (Q-TOF-MS) has emerged as being well suited to routine and high-throughput analyses of pharmaceuticals. Dietary supplements and functional foods have frequently been found to be contaminated with pharmaceuticals. In our continuous efforts to develop methodologies to protect public health against adulterated dietary supplements, we have constructed a mass spectral database for 21 H1-antihistamines encountered as adulterants by using liquid chromatography-electrospray ionization (LC-ESI)/Q-TOF-MS, and have proposed their possible collision-induced dissociation pathways...

There is a crosstalk between mood disorders and oxidative stress. Chlorpheniramine (CPA), a first generation antihistamine, is hypothesized to have an anxiolytic role at high doses; however, its antidepressant and antioxidant roles have not previously been investigated. The aim of the current study was to evaluate the antidepressant and anxiolytic effects of CPA treatment in association with nitric oxide (NO) and super oxide dismutase (SOD) activity in a mouse model of anxiety. BALB/c mice were divided into unstressed (naïve), control, and CPA- (0...

REVIEW
Nanette B Silverberg, Carola Durán-McKinster
Atopic dermatitis is the leading cause of pediatric dermatology visits in developed nations. Recurrent, itchy rashes in typical locations and a family/personal history of atopy helps to identify children with disease. Most cases (85%) are diagnosed by age 5 years. Some comorbidities are age-based and may affect disease course. Topical corticosteroids are the mainstay of therapy; corticosteroidphobia and side effects complicate use. Topical calcineurin inhibitors are alternatives to corticosteroids, especially in sensitive locations...
