SUMMARY One of the necessary steps in understanding behavior is to adequately classify the existing patterns associated with that behavior. The literature contains evidence for at least three common subtypes of inhalant users: (a) young inhalant users, (b) adolescent polydrug users who frequently use inhalants and (c) adult users. Several national and regional data sources are examined for the presence of these types and the categorization is generally upheld.

Two reports suggested that vitamin D2 is less effective than vitamin D3 in maintaining vitamin D status.Our objective was to determine whether vitamin D2 was less effective than vitamin D3 in maintaining serum 25-hydroxyvitamin D levels or increased the catabolism of 25-hydroxyvitamin D3.This was a randomized, placebo-controlled, double-blinded study of healthy adults ages 18-84 yr who received placebo, 1000 IU vitamin D3, 1000 IU vitamin D2, or 500 IU vitamin D2 plus 500 IU vitamin D3 daily for 11 wk at the end of the winter.Sixty percent of the healthy adults were vitamin D deficient at the start of the study. The circulating levels of 25-hydroxyvitamin D (mean+/-sd) increased to the same extent in the groups that received 1000 IU daily as vitamin D2 (baseline 16.9+/-10.5 ng/ml; 11 wk 26.8+/-9.6 ng/ml), vitamin D3 (baseline 19.6+/-11.1 ng/ml; 11 wk 28.9+/-11.0 ng/ml), or a combination of 500 IU vitamin D2 and 500 IU vitamin D3 (baseline 20.2+/-10.4 ng/ml; 11 wk 28.4+/-7.7 ng/ml). The 25-hydroxyvitamin D3 levels did not change in the group that received 1000 IU vitamin D2 daily. The 1000 IU dose of vitamin D2 or vitamin D3 did not raise 25-hydroxyvitamin D levels in vitamin D-deficient subjects above 30 ng/ml.A 1000 IU dose of vitamin D2 daily was as effective as 1000 IU vitamin D3 in maintaining serum 25-hydroxyvitamin D levels and did not negatively influence serum 25-hydroxyvitamin D3 levels. Therefore, vitamin D2 is equally as effective as vitamin D3 in maintaining 25-hydroxyvitamin D status.

The diagnosis of inhalant allergy can be elusive, with symptoms resembling viral or bacterial infection, as well as immunologic deficiency. In this study an inhalant allergy immunoassay was investigated as a possible screen to rule in or out respiratory inhalant allergy in patients with allergic-type symptoms. The results of this screen were compared in 192 serum specimens submitted to our laboratory for specific IgE allergy testing and 73 blood bank samples. When the discrepant results of the inhalant allergy immunoassay were resolved by Western blot, a final sensitivity of 94.7% and specificity of 97.5% was calculated. We have found this inhalant allergy immunoassay to be an effective screen for detecting inhalant allergies, and believe it to be ausefultool for the primary care physician or non-allergist trying to differentiate inhalant allergens from chronic sinusitis or other causes of sinopulmonary congestion.

The use of Phadiatop® in mass‐screening programmes of inhalant allergies: advantages and limitations
Summary The validity of Phadiatop® as a tool in the mass screening for inhalant allergies was investigated. Seventy‐nine out of 600 recruits (13.2%) were classified as allergic to inhalant allergens (68 oculorhinitis; 11 asthma) on the basis of positive history, confirmed by skin testing and/or RAST for the seven most common aero‐allergens in Italy. Another 74 subjects had positive RAST and/or skin tests, yet had never experienced allergic symptoms. Phadiatop was positive in 145/600: in 78 out of 79 allergies and in 67 RAST‐positive non‐allergies. Correlation between Phadiatop and RAST was statistically significant, though higher for grass pollens ( r = 0.85, P < 0.001) than for Dermatophagoides pteronyssinus ( r = 0.68, P < 0.01). PRIST (cut‐off 220IU/ml) identified 36/79 allergies (45.6% sensitivity, whereas that of Phadiatop was 98.7%). As the high percentage of cases in the unselected population had specific serum IgE against inhalant allergens and no allergic symptomatology, the Phadialop‐positive predictive value falls to 53.7%, thus creating the need for Phadiatop‐positive subjects to undergo further investigation for an appropriate diagnosis. Given this limitation, Phadiatop appears to be an important step forward in the field of mass‐screening programmes for inhalant allergies.

While the rate of inhalant abuse continues to rise in this country, it remains one of the least studied or discussed groups of abused substances. This review focuses on the current knowledge of the epidemiology, pharmacology, and sequela of inhalant abuse. We will discuss three groups of inhalants: volatile solvents, nitrous oxide, and nitrites. We will then conclude by proposing means by which inhalant abuse may be prevented and treated.
