Extramammary Paget disease with underlying hidradenoma papilliferum: guilt by association?

Extramammary Paget disease (EMPD) is a heterogenous entity representing either an intraepidermal adenocarcinoma in situ with apocrine differentiation or an expression of underlying malignancy of the skin or of the intestinal or genitourinary tract. The coexistence of EMPD with a benign underlying hidradenoma papilliferumn (HP) is, however, exceptional. We present the case of a 79-year-old woman with diffuse and patchy gray-white lesions involving her left vulva as well as an underlying 0.7-cm asymptomatic firm nodule. Histologically, the epidermis and dermis showed features characteristic of EMPD and HP, respectively. Malignant transformation in HP giving rise to EMPD in the overlying epithelium has been reported. In our case, however, failure to demonstrate continuity between the two lesions together with the lack of cytologic atypia, mitoses, and necrosis in the HP lends additional support to the possibility that the HP is "innocent" and that its association with EMPD is thus coincidental. A common histogenetic derivation of these two lesions from the mammary-like glands or from related germinative cells in the epidermis is suggested to explain this rare presentation.

Guilt, fear, stigma and knowledge gaps: ethical issues in public health communication interventions.

Public health communication campaigns have been credited with helping raise awareness of risk from chronic illness and new infectious diseases and with helping promote the adoption of recommended treatment regimens. Yet many aspects of public health communication interventions have escaped the scrutiny of ethical discussions. With the transference of successful commercial marketing communication tactics to the realm of public health, consideration of ethical issues becomes an essential component in the development and application of public health strategies. Ethical issues in public health communication are explored as they relate to eight topics: 'targeting' and 'tailoring' public health messages to particular population segments; obtaining the equivalence of informed consent; the use of persuasive communication tactics; messages on responsibility and culpability; messages that apply to harm reduction; and three types of unintended adverse effects associated with public health communication activities that may label and stigmatise, expand social gaps, and promote health as a value. We suggest that an ethical analysis should be applied to each phase of the public health communication process in order to identify ethical dilemmas that may appear subtle, yet reflect important concerns regarding potential effects of public health communication interventions on individuals and society as a whole.

Genomics. Microarrays--guilt by association.

DNA microarray analysis has provided a wealth of data on global patterns of gene expression but has yet to deliver on its early promise of identifying networks of interacting gene products. In his Perspective, Quackenbush discusses new work (Stuart et al.) that uses evolutionary conservation of gene expression patterns in yeast, worm, fruit fly, and human in an attempt to identify functionally related groups of genes.

Development. p73--guilt by association?

It has been assumed that the new members of the p53 protein family, p63 and p73, would have the same job as p53, namely, forcing cells to die if they or their DNA is damaged. Now, as Morrison and Kinoshita explain in their Perspective, one particular form of p73 has been found to be a survival factor rather than a death factor for sympathetic neurons during development (Pozniak et al.).

Ataxia, peripheral neuropathy, and anti-gliadin antibody. Guilt by association?

Some authors contend that patients with idiopathic neurological disease who are also anti-gliadin antibody seropositive are gluten sensitive. However, anti-gliadin antibodies lack disease specificity being found in 10% of healthy blood donors. We report a study comparing anti-gliadin antibody with other food antibodies in patients with idiopathic ataxia (20), hereditary ataxias (seven), or idiopathic peripheral neuropathy (32). Patients were HLA typed. IgA anti-tissue transglutaminase antibodies (tTG) were measured. No case was positive for IgA anti-tTG making occult coeliac disease unlikely. HLA DQ2 and HLA DQ8 were found distributed equally across all patient groups and unrelated to gliadin antibody status. HLA DQ2 expressing, anti-gliadin antibody positive cases (so called "gluten ataxia") were rare in our clinics (four cases in 2 years from a population of 2 million). We conclude that coeliac disease per se is not commonly associated with either idiopathic ataxia or idiopathic peripheral neuropathy. Our study also casts doubt on the nosological status of "gluten ataxia" as a discreet disease entity. All food antibodies tested, particularly IgG, were a common finding in both ataxia and peripheral neuropathy groups. No particular food antibody was associated with any patient group. Food antibodies were equally common in hereditary ataxias. We conclude they are a non-specific finding.
