Corneal collagen cross-linking with riboflavin, also known as collagen cross-linking (CXL), involves the application of riboflavin solution to the eye that is activated by illumination with ultraviolet A (UVA) light. We survey here the topographic corneal changes one year after CXL in patients with corneal keratoconus. ⋯ Our study showed a significant improvement in topographic corneal changes and refractive results in patients with corneal ectasia after CXL.

Methanol poisoning is one of the most important poisoning due to drinking of illegal and non-standard alcoholic beverage in some countries. Relatively limited studies have been carried out to identify the prognostic factors in methanol poisoning. ⋯ Regarding the results of this study, it can be suggested that coma, PaCO2 and hyperglycemia on admission time could be used as strong predictors of poor outcome.

Sulfur mustard (SM) is an incapacitating chemical warfare agent, which has been widely employed in particular regions including Iran. We investigated and reported delayed biochemical and hematological complications of SM in severely toxic Iranian veterans 23 years after exposure. ⋯ Results showed that SM can cause long-term effects on some biochemical factors of veterans. As many of the functional tests of liver and kidney between two groups were statistically unchanged, it seems that the observed biochemical changes may be secondary to delayed respiratory complications of the patients.

Fractures of distal radius are one of the most common fractures seen by physicians and account for 20% of all fractures seen in the emergency room. Various factors contribute in secondary displacement of fracture fragments after anatomic or near anatomic close reduction and cast immobilization in distal radius fractures. This study was designed to examine the correlation between radiographic outcomes in the closed treatment of unstable distal radius fractures and different risk factors. ⋯ Among the variables, the most important predictors of redisplacement after an acceptable closed reduction were loss of radial height, loss of radial inclination, and age.
