“…Positive results of testing for specific IgE antibody to allergens must be correlated with history and physical findings to assess their clinical significance. 210,211 A positive immediate hypersensitivity skin test in the absence of symptoms has been shown to be a significant risk factor for the later development of seasonal allergic rhinitis. 4,14,15 Special diagnostic techniques [Summary Statement 42] Special diagnostic techniques may be useful in selected cases.…”

“…Skin test positivity must be combined with reported symptoms, increased symptom scores, or physical signs during a known pollen season, controlled laboratory, or environmental exposure unit challenges. 210,211 A careful history is the most important step toward the diagnosis of allergic disease. Skin testing to allergens is indicated to provide evidence of an allergic basis for the patient's symptoms, to confirm suspected causes of the patient's symptoms, or to assess the sensitivity to a specific allergen.…”

“…On the basis of this, we would expect similar female-determining regions in the other two genera within the Myricaceae family. Sex markers can be used in the early selection of female plants for ornamental use, eliminating most male plants that may cause pollen allergy (Jacinto et al, 1992).…”

Morella rubra, red bayberry, is an economically important fruit tree in south China. Here, we assembled the first high-quality genome for both a female and a male individual of red bayberry. The genome size was 313-Mb, and 90% sequences were assembled into eight pseudo chromosome molecules, with 32 493 predicted genes. By whole-genome comparison between the female and male and association analysis with sequences of bulked and individual DNA samples from female and male, a 59-Kb region determining female was identified and located on distal end of pseudochromosome 8, which contains abundant transposable element and seven putative genes, four of them are related to sex floral development. This 59-Kb female-specific region was likely to be derived from duplication and rearrangement of paralogous genes and retained non-recombinant in the female-specific region. Sex-specific molecular markers developed from candidate genes co-segregated with sex in a genetically diverse female and male germplasm. We propose sex determination follow the ZW model of female heterogamety. The genome sequence of red bayberry provides a valuable resource for plant sex chromosome evolution and also provides important insights for molecular biology, genetics and modern breeding in Myricaceae family.

“…Nevertheless, every positive result must be correlated with history and physical fi ndings since a positive skin reaction does not necessarily imply the diagnosis of allergy. 19 Interpretation of skin tests is highly dependent on the constitutive allergenicity, potency and stability of the allergen extract. For this reason, SPT sensitivity tends to be higher among aeroallergens, in particular pollens, house dust mite, fungi and certain epidermals.…”

Skin testing remains an essential diagnostic tool in modern allergy practice. A signifi cant variability has been reported regarding technical procedures, interpretation of results and documentation. This review has the aim of consolidating methodological recommendations through a critical analysis on past and recent data. This will allow a better understanding on skin prick test (SPT) history; technique; (contra-) indications; interpretation of results; diagnostic pitfalls; adverse reactions; and variability factors. Skin has an important physiological role in the internal balance homeostasis and constitutes a crucial barrier against external aggressions, with well-known immunological properties. 1 It has been used by allergists for decades as an easily assessed laboratory of the immunological status of the individual.The fi rst skin testing technique was developed by Charles H. Blackley in 1865, a Manchester homeopathic physician with allergic rhinitis. He abraded a quarter-inch area of his skin with a lancet and then applied grass pollen grains. 2 The so-called scratch test was later adopted by Schloss for the diagnosis of food allergy in children. 3 Epicutaneous tests can be divided into scratch tests and prick/puncture tests. The fi rst method, proposed by Blackley 2 , implied a linear scratch without drawing blood and could either be performed fi rst, with the extract then dropped on the abraded skin, or be made through a drop of extract. 4 Although it was used extensively in the past, this technique became progressively obsolete due to patient discomfort, poor reproducibility, possible residual lesions and newer and innocuous procedures. 4 Therefore, scratch test is mentioned here for historical purposes only. It was Sir Thomas Lewis who, in 1924, fi rst applied skin prick tests (SPT). 5 Nevertheless, their generalised use in clinical practice only became a reality about 30 years ago, as a result of technique modifi cations proposed by Pepys. 6 For the purpose of this review and for easier comprehension, skin testing will be referred interchangeably as SPT, whatever device is used for its application.In 1966, Ishizaka's work on immunoglobulin E (IgE) and immediate hypersensitivity reactions 7 established the scientifi c corpus to what was done till then on a strictly empiric basis.As written by Dr Walzer in 1974, "the fact that skin testing has not turned out to be a simple and completely reliable technique does not detract from the fact that, when it is intelligently and skilfully performed, it remains the most effective diagnostic procedure in reaginic allergic disorders". 8 The reliability of skin testing and proper documentation of test results are essential in allergy practice. A recent survey to all physician members and fellows of the American College of Allergy, Asthma and Immunology practicing in the
