Allergic rhinitis (AR) is rarely found in isolation and needs to be considered in the context of systemic allergic disease associated with numerous comorbid disorders, including asthma, chronic middle ear effusions, sinusitis, and lymphoid hypertrophy with obstructive sleep apnea, disordered sleep, and consequent behavioral and educational effects. The coexistence of allergic rhinitis and asthma is complex. First, the diagnosis of asthma may be confused by symptoms of cough caused by rhinitis and postnasal drip. ⋯ Prospective cohort studies are required to assess the disease burden caused by allergic rhinitis in childhood, its consequences due to delay in diagnosis and treatment, and to further assess the potential educational impairment that may result. Because allergic rhinitis is part of a systemic disease process, its diagnosis and management require a coordinated approach by the specialist in allergy-immunology-rhinology rather than a fragmented, organ based approach. There are other clinical presentations such as recurrent infections of the upper respiratory tract, as well as pharyngeal and laryngeal disorders.

The skin prick test is used to diagnose the allergic sensitization. Its results depend upon several factors, such as the lancet type. In Cuba, the most frequently used are: ALK lancet and blood lancet. ⋯ The ALK lancet showed more precision, sensitivity and specificity and it was preferred by the patients.

H. pylori is considered one of the major etiological agents for chronic idiopathic urticaria; it infects 15 percent of the world's population and induces an inflammatory process in the gastric mucosa. In some cases it is related to chronic urticaria, even in the absence of digestive symptoms. ⋯ We found a correlation between the disappearance of the symptoms and a negative urea breath test in 45 percent of the patients who were studied. We must consider the possibility of H. pylori infection, which can be present even without gastric symptoms.

To determine the time course of the expression of five toll-like receptors (TLRs 1-5) in mixed blood mononuclear cells and their relationship to pro-inflammatory and anti-inflammatory cytokines during acute respiratory distress syndrome (ARDS). ⋯ Thus, TLRs gene dysregulation and cytokine profiles are probably important prognostic factors for patient outcome and survival after ARDS.

Allergy to local anesthetics in dentistry. Myth or reality?
Local anesthetics are drugs frequently used in dentistry. Although they are usually well-tolerated drugs, sometimes, they can cause adverse reactions of different kinds and severity. True incidence of local anesthetics' allergic reactions is unknown. ⋯ The allergic reactions to the local anesthetics are very rare and most of the adverse reactions are psychogenic/vasovagal. These facts should be known by the physician and by the dentist in order to minimize the frequent fears and "myths" about the use of local anesthetics at the dentist office.
