  • Glaucoma from PC usage
    Michael -

    Dear Editor

    As a PC user this article interests me greatly, as I have noticed my eyesight deteriorating since working 11 hour a day shifts in front of 4 monitors and sometimes also using the computer again after work at home.

    From a lay man's perspective I would like to know more about how different types of screen affect the eyes, and indeed whether the problem may stem simply from levels of artificial...

  • Response to the article on diabetes prevalence 1996-2005 (Masso-Gonzalez et al)
    Greg Fearn

    Dear Editor

    I'm unclear as to why the issue of screening / recording in primary care has been so readily dismissed as a cause of the increase in prevalence of diabetes. Having worked in this area from 1997 onwards I have seen the evoloution of data quality in primary care have a profound effect on prevalence levels for diabetes. The additional focus of the QoF indicators for the general practitioner contract and th...

  • Fundamental Bias About Relation HPV and Cervical Cancer.
    Sergio Stagnaro

    Editors

    As I illustrated earlier, all researches on the relation between type 16 and 18 HPV and cervical cancer, as well as its primary prevention with anti HPV vaccine, although honestly performed in a worthy manner, are fundamentally biased (1-14. In fact, I have underscored a fundamental bias, overlooked distressingly and suspiciously, in all researches on the relation between papillomavirus (especially 16, 18...

  • The World Health Organization and global smallpox eradication
    Christian T. K.-H. Stadtländer, PhD, MPH, MBA

    Dear Editor

    I read with interest the article by Bhattacharya [1] about the role of the World Health Organization (WHO) in the development of the smallpox eradication program. The author provides information about the inner workings of the WHO in the 1960s and 1970s and described the various political, economic, and social conditions under which WHO officials, field managers, and public health workers attempted to...

  • Impact of Maternal depression on child heatlh
    Rajan R Patil

    Dear Editor

    Some forms of maternal morbidity may not kill mothers, but have the ability to incapacitate them, enough to make them vertually non-existent, as far as their infant is concerned e.g. Post Partum psychosis/depression is one such, which is quite commonly observed in many mothers following delivery, understood to be triggered by interplay of hormones due to pregnancy related physiology during and immediat...

  • This could be due to increased testosterone.
    James M. Howard

    Dear Editor

    It is my hypothesis that human evolution occurred because of increases in testosterone (Rivista di Biologia / Biology Forum 2001; 94: 345-362). Testosterone is highest in humans and testosterone levels of the great apes directly parallel relatedness to humans. According to my explanation of human evolution, testosterone will periodically increase within populations and periodically decrease. I suggest...

  • Inheriting behaviour or biology?
    M Justin S Zaman

    Most data on ethnic inequalities in health will have studied ‘first- generation’ migrants from South Asia, as even the oldest second-generation South Asians are only now in 2009 beginning to enter their 40s.

    Smith et al’s[1] pertinent question is to ask whether the sons and daughters of first-generation South Asians will be at equal risk of poor health. The case of coronary disease is of particular importance con...

  • Body mass index threshold for obesity using self-reported data among Australian population.
    Zumin Shi

    Dear Editor

    Under-reporting of weight and over-reporting of height are problems in estimating the prevalence of obesity. [1] However, many studies rely on self-report methods. Dauphinot et al. suggested using BMI≥ 29.2 kg/m2 for the definition of obesity based on self-report height and weight in Swiss population. [2]

    Using data from North West Adelaide Health Study in Australia, [3, 4] we as...

  • Tobacco retail provision and smoking
    Frank J van Lenthe

    Editor - An improved understanding of the role of place for health is one of the main challenges in social epidemiology [1]. To contribute to this challenge, many studies are concerned with the identification of environmental characteristics related to health. As a consequence of the early phase of research in this field, a majority of these studies employ a cross-sectional design. Recent papers in the Journal have descri...

  • Authors' reply
    Virginie Dauphinot

    We are grateful to Faeh and al. for having applied the reduced obesity threshold that we proposed on their data. Our purpose was not to define an universal cut-off of 29.2 kg/m2 as a new definition of obesity, but rather to demonstrate that using the simplest correction method i.e. reducing the obesity threshold, was effective in estimating the true obesity prevalence in our population samples, rather than usi...
