  • Male Pattern baldness and its association with coronary heart disease: a meta-analysis: letter to the editor
    Pooja Arora

    Editor, The meta-analysis conducted by Yamada et al (2013) has established the association between baldness and coronary heart disease (CHD). The authors have concluded that vertex baldness among young men is closely related to atherosclerosis. Another factor that deserves mention in this context is smoking. We have many a times come across patients with severe arterial disease who have baldness and gray hair and on histo...

  • Students' attitude and smoking behaviour following the implementation of a university smoke-free policy: a cross-sectional study 1. Monique Chaaya1, 2. Maysam Alameddine1, 3. Rima Nakkash2, 4. Rima A Afifi2, 5. Joanna Khalil2, 6. Georges Nahhas1 + Author…
    Charles O. Gundo

    While I am pleased with the general research, its significance and findings in part, it is my humble concern that there may have been a systematic error in the sampling design. The researchers set out to measure both attitude towards and compliance with the smoking ban. In measuring attitudes, the researcher correctly identifies the school students as the population and randomly picks classes on which the instrument is...

  • Prevalence and predictors of delirium
    Niamh A. O'Regan

    Sir, we read with interest the recent response to our study of delirium point prevalence from Zieschang and colleagues, Heidelberg, Germany[1]. Zieschang et al have described a delirium prevalence of 15.6% in their study population of older hyponatraemic patients and normonatraemic controls admitted to a step-down facility, and note that our hospital-wide point prevalence was higher at almost 20%[2].

  • Androgens and the association of male pattern baldness with coronary heart disease
    C. Mary Schooling

    Yamada et al. present a fascinating meta-analysis showing that male pattern baldness is associated with coronary heart disease (CHD).1 Although the association is subject to the inevitable limitations of observational studies, it is an intriguing observation for which Yamada et al. provide several potential mechanisms, such as classical coronary risk factors, hyperinsulinaemia or chronic inflammation causing both baldness...

  • Blue but true?
    Michael Sharpe

    We read the report of this trial with interest. The topic of the management of comorbid depression in chronic illness is an important one. We acknowledge the considerable effort involved in mounting a trial such as the TrueBlue study. However, we also feel it is important to raise comment on the reported findings, to ensure they are not misinterpreted. Our comments are:

    First, the trial was not of depressive di...

  • Prevalence and predictors of delirium
    Tania Zieschang

    The point prevalence of delirium in an acute care facility in Ireland was described with 20% for the 280 patients enrolled in the study. Prevalence was the highest on the geriatric ward (8/15 patients, 53%) and in patients >80years of age (24/69 patients, 34.8%) [1]. Delirium prevalence appears to be very high when compared to our own data set (Clinical trial registration: DRKS00004280). In a case-control-study, which...

  • Cadmium and proteoglycans
    Heikki Savolainen

    Dear Editor,

    This excellent paper?s conclusions concur my earlier findings on the effects of cadmium on the urinary proteoglycan excretion (1). It seems that changes are e.g. related with proteinuria (2) and thus be considered as markers for more generalized vascular effects as predicted in the current investigation.
