Background And Objectives: Spider leg veins are telangiectasias located intracutaneously. This condition poses a cosmetic problem.
Study Design/patients And Methods: The purpose of this study was to determine what influence the KTP (532 nm) laser has on spider leg veins dependent on the vascular diameter and to what extent the skin has been affected. Seventy female patients were treated in three laser sessions. Analysis was done 30 weeks after the last laser treatment session.
Results: Fifty-six patients completed the study. In group 1 (vascular diameter < or = 0.6 mm), spider leg veins were no longer visible in 33%; in 40%, a decrease in vascular diameter could be observed; in 27%, no change in size occurred. In group 2 (vascular diameter 0.7-1.0 mm), laser-treated spider leg veins were visible in all patients. Hyperpigmentation occurred in 13 patients.
Conclusions: The KTP (532 nm) laser is an effective for treating spider leg veins having a vascular diameter under 0.7 mm.

Behavioral corroboration that Saitis barbipes jumping spiders cannot discriminate between males' red and black ornaments.

Physiological or genetic assays and computational modeling are valuable tools for understanding animals' visual discrimination capabilities. Yet sometimes, the results generated by these methods appear not to jive with other aspects of an animal's appearance or natural history, and behavioral confirmatory tests are warranted. Here we examine the peculiar case of a male jumping spider that displays red, black, white, and UV color patches during courtship despite the fact that, according to microspectrophotometry and color vision modeling, they are unlikely able to discriminate red from black.

Both veins experienced significant compression - OLCIV proximally and ILCIV medially - due to the overlying right common iliac artery (RCIA) and lumbar spine. The patient presented with bilateral spider veins, lower extremity swelling, pelvic discomfort, and bilateral leg cramping.

Background: Huber, 2005 contains 52 species distributed in Cambodia, China, Laos, Thailand and Vietnam, out of which about 34 species have been recorded from China. It can be distinguished from all other genera of Pholcidae by the male chelicerae with lateral ledges and the cheliceral apophyses with cuticular ridges or scales. The femur of the male palp features a retrolateral apophysis.

Article Synopsis
- Researchers have successfully applied spider silk fibers in nerve repair for the first time in humans, following previous successful sheep trials.
- Four patients with nerve defects greater than 20 cm were treated using spider silk conduits within their veins, showing promising results over a follow-up period of 2 to 10 years.
- All patients experienced primary healing without adverse effects, and many regained significant sensory and motor function, indicating spider silk conduits could be a viable option for complex nerve repairs.
