ing from these five main categories, we found that “mothering is overwhelming” is the core experience of PPD symptoms for low-income women. The demands of parenting small children, along with mothers’ ambivalence, isolation, juggling, and real-life worries, converged to produce an understanding of PPD as feeling overwhelmed by both the material and emotional demands of mothering in the context ...

We examined the effectiveness and efficiency of 2 instructional arrangements using progressive prompt delay (PPD) with 3 young children with autism and 1 child with developmental delays. Specifically, we compared PPD with instructive feedback (IF) to PPD without IF in an adapted alternating treatment design. The results suggested that (a) children with autism and developmental delays can learn ...

The tuberculin skin test (TST) using purified protein derivative (PPD) of Mycobacterium tuberculosis is traditionally used to diagnose latent tuberculosis (TB) infection (LTBI). However, LTBI diagnosis by peripheral blood mononuclear cell (PBMC) interferon (IFN)-gamma responses to M. tuberculosis-specific antigens, early secreted antigenic target 6 kDa (ESAT-6) and culture filtrate protein (CFP...

BACKGROUND Cross-reactions and co-sensitizations are of great importance in understanding contact allergy and exposure sources. OBJECTIVES To investigate common cross-reactions and co-sensitizations in p-phenylenediamine (PPD)-sensitized and toluene-2,5-diamine (TDA)-sensitized individuals. METHODS From our patch test population, 8036 patients patch tested with the European baseline series ...

The production of a macrophage migration enhancement factor (MEF) has been achieved as a consequence of administering a desensitizing dose of purified protein derivative (PPD) to Mycobacterium bovis BCG-sensitized rabbits. The migration-enhancing effect was first demonstrated when alveolar macrophages (AM) harvested from desensitized rabbits exhibited marked migration stimulation; whereas maxim...

Because of a rise in postpartum depression (PPD), the U.S. Department of Health and Human Services recently indicated a need for more studies of possible risk factors for PPD. PPD can continue for months or years after birth and has consequences for the family as a whole. Past research has not investigated the relationships between abuse, whether physical, sexual, or emotional, and PPD. The aim...

We evaluated the performance of two homogeneous assays for quantifying HDL cholesterol (HDL-C) and compared them with the phosphotungstic acid (PTA)/ MgCl2 assay. Both homogeneous HDL-C assays were precise, having a within-run CV of < 1.20% and a between-run CV of < 4.07%. The HDL-C values (y) measured by the two homogeneous methods correlated well with those by the PTA/MgCl2 method (x): y = 1....

BACKGROUND Pigmented purpuric dermatoses (PPD) are a spectrum of disorders characterized by a distinct purpuric rash. Although PPD can be easily diagnosed, the disease entity remains an enigma and a therapeutic challenge. OBJECTIVE The purpose of this study was to investigate the characteristics and clinical manifestations of PPD and to elucidate the relationship between assumed etiologic fac...
