Pathologic phimosis is a common problem throughout the world. In Europe, Asia, South America, and Central America neonatal circumcision is not routinely performed, thus childhood phimosis is not rare. In addition, in the United States and Canada the rates of neonatal circumcision, estimated to be 60% to 90%, 5 are declining. 9 Thus, even in the United States and Canada, phimosis is a commonly faced problem. Obviously, one of the difficulties that arises when studying phimosis is the lack of a clear definition and differentiation between a pathologic phimosis and a physiologic nonretractile foreskin. 10 In our study, nonretractable and pinpoint prepuces correspond to type II and type I of the classification by Kayaba et al. 11 The cases classified as ''retractable'' phimosis might not be considered pathologic by others because of a potential for spontaneous resolution with increasing age. However, all patients included in our study were originally referred for circumcision, they all had a constrictive ring for which they had sought medical attention, and they would have been considered candidates for circumcision if topical therapy had not been offered. [CIRP note: These doctors show the common inability to distinguish between normal in childhood developmentally narrow foreskin and a pathological condition called phimosis.]

Intravenously administered glucocorticoids , such as prednisone , are the standard of care in acute GvHD [7] and chronic GVHD. [24] The use of these glucocorticoids is designed to suppress the T-cell-mediated immune onslaught on the host tissues; however, in high doses, this immune-suppression raises the risk of infections and cancer relapse. Therefore, it is desirable to taper off the post-transplant high-level steroid doses to lower levels, at which point the appearance of mild GVHD may be welcome, especially in HLA mis-matched patients, as it is typically associated with a graft-versus-tumor effect.

Cyclosporin binds to the cytosolic protein Peptidyl-prolyl cis-trans isomerase A (known as cyclophilin), while tacrolimus binds to the cytosolic protein Peptidyl-prolyl cis-trans isomerase FKBP12. These complexes inhibit calcineurin, block dephosphorylation of the transcription factor NFAT of activated T-cells and its translocation into the nucleus [25] . Standard prophylaxis involves the use of cyclosporine for six months with methotrexate. Cyclosporin levels should be maintained above 200 ng/ml [26] . Other substances that have been studied for GvHD prophylaxis include, for example: sirolism, pentostatin and alemtuzamab [27] .
