In this second part, we study 102 cases of epithelioma of the anterior margin of the larynx. The authors insist on the need for bilateral treatment of lymphatic areas on account of their frequent bilateral involvement, jumping from 9% for N0 to 80% for a fixed unilateral enlarged lymph node. Whatever the T stage, the best therapeutic results are provided by total or partial surgery of the lesion combined with surgical treatment of lymphatic areas completed by irradiation.

Purpose: To describe a technique involving combined endothelialectomy and trypan blue staining to allow for improved visualization and Descemet membrane (DM) removal during endothelial keratoplasty.
Methods: Endothelialectomy with 2 disposable endothelial irrigating cannulas (Vortex and Sterimedix) and an irrigation-aspiration handpiece are described. Several passes over the desired area are made to ensure adequate endothelialectomy treatment.

The pine leafhopper genus Viraktamath & Sohi was previously classified within the tribe Grypotini. In a recognized classification system, it has been categorized as the subtribe Grypotina of the tribe Koebeliini within Deltocephalinae, based on morphological characteristics such as a crown exhibiting few transverse fine striations along the anterior margin; short antennae measuring less than 1.5 times the head length but not extending to half or more of body length; ocelli positioned below the anterior margin of the crown and not visible from above, with a considerable distance from the eyes; and an anteclypeus that is narrow and tapered beyond the anterior margin of gena, alongside metatarsomere I presenting platellae on the plantar surface.

The lower limb is vascularized by the femoral artery, which continues as the popliteal artery. After the distal margin of the popliteus muscle, the popliteal artery divides into the anterior and posterior tibial arteries. Anatomical variations in the bifurcation of the popliteal artery are frequent.
