Hmm weird - not sure what happened there! They're free open access links
Reposted with correct links (though many 'actual studies' are restricted to subscribers - it doesn't make them less robust

Though if its not the Mallon study you're referring to anyway, perhaps you could be a little less oblique?
Hi Cote
Do you mean this study?
archderm.jamanetwork.com/article.aspx?articleid=190052
It looks at both contagious and non-contagious penile disease.
If so you may be interested in the criticism it generated in terms of poor experimental design and lack of accountability of lifestyle factors

As we've said before there are benefits to circumcision in regions without access to regular washing facilities/healthcare but that argument is difficult to support in the modern-day UK - what we can say is that those facilities exist but that education/understanding of risks may be a barrier.
Interestingly the Mallon paper does not look at disease epidemiology or compare the number of non-circumcised diseased individuals with non-circumcised non-diseased individuals in the general population and so you cannot make any assertions as to the risks of not being circumcised.
For example: "All patients with Zoon balanitis, bowenoid papulosis, and nonspecific balanoposthitis were uncircumcised" is meaningless unless you know the prevalence of those diseases in the non-circumcised population - they may only occur in non-circumcised men, but if they only occur in (for example) one in a million non-circumcised men, then you'd be circumcising a million babies (who would have to undergo an unnecessary surgical procedure) to protect one of them from future disease. Is it a justifiable cost-benefit?
Assuming that circumcision is the best way of reducing risks is a flawed argument - it's the same 'precautionary mutilation' argument that is still used to try and justify tail docking in dogs - yet for spaniels for example, you'd have to dock over 300 tails as puppies to prevent one adult tail amputation due to injury.
Additionally the study does not account for significant risk factors such as number of sexual partners (which you may assume to be lower in religious communities where marriage is encouraged and circumcision is also practiced) so its impossible to separate the confounding factor of the number of sexual partners a person may have from the perceived 'benefits' of circumcision.
The study does also not look at educational attainment, hygiene practices or barrier contraception use, so you cannot assume that the non-circumcised men presenting with disease in this study were engaged in these protective practices despite living in modern Britain. If they weren't then that may account for the differences between the two populations.
Overall its not a particularly strong paper - you could just as easily conclude that religious belief confers protection by limiting the number of sexual encounters a person may have (if they had investigated this confounding factor)
