Th? main object of this paper is to put before the readers: (1) the various points of interest with regard to the life-history, pathogenicity of filaria bancrofti, and the etiology of elephantiasis, lymphangitis, etc., (2) the several problems, so far solved, and those yet to be solved, in connection with the above, (3) to discuss certain features that are peculiar to filarial diseases, and als...

How cells coordinate their spatial positioning through intercellular signaling events is poorly understood. Here we address this topic using Caenorhabditis elegans vulval patterning during which hypodermal vulval precursor cells (VPCs) adopt distinct cell fates determined by their relative positions to the gonadal anchor cell (AC). LIN-3/EGF signaling by the AC induces the central VPC, P6.p, to...

The Caenorhabditis elegans vulva develops from the progeny of three vulval precursor cells (VPCs) induced to divide and differentiate by a signal from the somatic gonad. Evolutionarily conserved Ras and Notch extracellular signaling pathways are known to function during this process. To identify novel loci acting in vulval development, we carried out a genetic screen for mutants having a protru...

Of 59 women referred with vulval warts whose cervices were assessed colposcopically for the presence of cervical intraepithelial neoplasia (CIN) before local treatment of the wart lesions, 17 had histologically proved CIN, 12 had histologically proved cervical wart virus infection, and 30 had abnormality on colposcopy or cytology. Seven of the 17 with CIN had no abnormality on cervical cytology...

Extrapulmonary involvement can occur in isolation or along with a pulmonary focus as in the case of patients with disseminated tuberculosis. Vulval TB is very rare and the presentation can be quite variable, and may be misdiagnosed as sexually transmitted disease. We herein report a young lady with disseminated TB presenting as Vulval TB.
