Coexistence of Syphilis and Psoriasis

Abstract

Psoriasis is a chronic inflammatory skin disease with various triggering factors. Here we report a case of psoriasis coexisti ng with secondary syphilis which could have been a possible trigger for exacerbation of psoriasis. KEYWORDSPsoriasis, Secondary Syphilis.

Spectroscopic and Radiative Properties of Several Nd3+ Ions in Borate Glass System

“…There is one material [28] shown that intensity parameters  2 < 2, this condition represent the high covalent bonding that means there was broadening asymmetry around the environments glass [18]. Table 2 showed generally was observed that  2 >  4,6 [2,20,30,31,31,33] indicate the higher covalency of the ion-ligand bond lower symmetry of the Nd 3+ ion site. This result also explained that the higher intensity of hypersensitive transition and the nephelauxetic effect possessed by these glass [22].…”

“…The higher values of  4 and  6 [20,22,28,32,34] for the glasses indicated their mechanics have higher rigidity. Then, the spectroscopic quality factor known from  = ( 4 / 6 for to find the channel through which the excited metastable state to the ground state [2].…”

“…The above related to Nd 3+ laser application such as optical amplifier, laser pumping, optical communication, optical waveguide, storage data optically, radar and medical instrumentation [1][2][3][4][5]. Medium gain laser characteristics for commercial laser required were must satisfied sharpness fluorescent lines, strong absorption bands and sensible for high quantum efficiency in accordance with the needed transition photon [6].The above requirements have been obtained by a small amount of concentration Nd 3+ ions-doped glass material, since Nd 3+ ions were able to produce population inversion for result stimulated emission in the visible range (such as emission transition at 4 G 7/2  4 I 9/2 , 4 G 7/2  4 I 11/2 , 4 G 7/2  4 I 13/2 ) [7] and the NIR range (lasing transition 4 F 3/2  4 I 9/2 , 4 F 3/2  4 I 11/2 , 4 F 3/2  4 I 13/2 ) [1].…”

“…Improved laser performance is strongly influenced by the composition of the host glass matrix and the concentration of doped ions, since the stimulated emission quality depends on host matrix in which the ions are incorporated [7,8]. Several types of commercial glass are generally used as a laser host matrix, i.e silicate, phosphate, borate glasses and several heavy metal oxide glasses [1,2,7,9]. Some of the results showed that the silicate glasses has its advantages as well as high chemical stability, high transparency for UV, low thermal expansion coefficient leading to strong thermal resistance, a small nonlinear refractive index, high surface damage threshold, large tensile fracture strength and good durability [10][11][12].…”

“…Phosphate glass appropriately used as a host matrix for Nd 3+ ions owned properties are low thermal-optical constants, low melting point, low glass transition temperature and high thermal expansion coefficient [14]. Moreover, the borate glass properties have been reported as well high transparency, high density, appropriate bandwidth, suitable for infrared transmission, high mechanical stability, corrosion resistivity and inexpensive [2,15]. In addition, the other types of glasses and crystals have been reported as well as a host of Nd 3+ ion laser such as Nd 3+ doped alkali niobium zinc tellurite glasses [16], Nd 3+ doped barium titanium silicate glasses [17], Nd 3+ ions in fluoro-phosphate glasses [18], Nd 3+ doped lanthanum calcium borate glasses [19] and Nd 3+ doped alkali boro germanate glasses [20].…”
