Urethritis membranacea desquamativa

Non-specific urethritis.

Asymptomatic non-specific urethritis.

Non-specific urethritis is without doubt the commonest form of urethritis in men. The reported figures of cases of non-gonococcal urethritis for England and Wales, since they were first recorded separately in 1951, have steadily increased from 10,794 to 35,721 in 1968 (Department of Health and Social Security, 1969). The majority of these cases of non-gonococcal urethritis are non-specific in n...

Non-specific Urethritis*

The editorial of a recent number of the British Journal of Venereal Diseases (1953) stressed the problem of non-specific urethritis. The prevalence of the disease was noted, namely 10,794 new male cases in 1951 compared with 14,975 new male cases of gonorrhoea. Mention is then made of the possibility of a virus, and of organisms of the pleuropneumonia group being the cause. In conclusion it is ...

Arthritis and venereal urethritis.

The clinical course of arthritis associated with venereal urethritis was clearly defined before 1900. Brodie (1818, 1836), Fournier (1868-69), and Launois (1899) published excellent descriptions of the disease, noting the predilection of the arthritis for the joints of the lower extremities, the relapsing course, and the frequency of complications affecting the eyes. Launois gave an accurate ac...

Conserved traits of spiralian development in the bryozoan Membranipora membranacea

Background: Spiral cleavage is a remarkably conserved pattern of embryogenesis present in animals of the clade Spiralia, such as annelids, molluscs, flatworms and nemerteans. However, not all spiralians display spiral cleavage. Recent phylogenies suggest that the spiral arrangement of embryonic blastomeres is an ancestral trait for the Spiralia and that it was secondarily modified in several sp...
