Testosterone administration in female-to-male transsexual subjects aims to develop and maintain the characteristics of the desired sex. Very little data exists on its effects on sexuality of female-to-male transsexuals. The aim of this study was to evaluate sexual function and mood of female-to-male transsexuals from their first visit, throughout testosterone administration and after sex reassignment surgery. Participants were 50 female-to-male transsexual subjects who completed questionnaires assessing sexual parameters and mood. The authors measured reproductive hormones and hematological parameters. The results suggest a positive effect of testosterone treatment on sexual function and mood in female-to-male transsexual subjects.

Cleft lip with or without cleft palate (CL/P) is the most common inborn craniofacial anomaly. Affected individuals require extensive medical and psychosocial support. Although CL/P has a complex and poorly understood etiology, increasing evidence of folate pathway involvement has been collected. So far, only the MTHFR gene has been extensively investigated as a risk factor for CL/P, while little has been done to test genetic variations in the folate biosynthetic pathways that may influence the infant's susceptibility to these birth defects. To date, this paper presents the first attempt to verify the involvement of four genes belonging to the folate pathway in nonsyndromic cleft onset. We used a case-parent triad design to test for linkage disequilibrium in the case of seven SNPs mapping on four different genes: transcobalamin 1 and 2 (TCN1 and TCN2), methionine synthase (MTR), and MTR reductase (MTRR). Our finding suggests that TCN2 is involved in causing CL/P. Indeed, significant overtransmission of the C allele was observed at the polymorphism c.776C>G (p.Pro259Arg) to the affected offspring (P=0.01). Results obtained with additional TCN2 polymorphisms suggest that c.776C>G may be functionally related to CL/P. However, because conflicting data exist with regard to the effect of the polymorphism in transcobalamin 2 function or in perturbing plasma levels of key molecules in the folate pathway, further investigation is warranted to confirm our data.

Three patients affected by carcinoma cuniculatum involving the nail apparatus are reported. The toes were affected in 2 cases, the thumb in 1 case. In the first patient the tumour developed in the subungual area and resulted in loss of the toe-nail. In the second patient the tumour originated on the dorsum of the toe and subsequently involved the proximal nail fold. In the third patient the tumour developed in the nail bed resulting in loss of the lateral part of the nail plate. The pathology showed in all cases invaginating strands of well-differentiated keratinocytes, some of which had central crypts containing keratinous debris. Radical excision of the tumour required disarticulation of the digit in 2 cases, whereas Mohs micrographic surgery was performed in the third case.

The authors can assume that, similar to the alar cartilage, the septum can be repositioned during the primary surgery, without causing growth anomaly, improving the morphologic/functional results.
