I briefly review CP violation in the B system, concentrating on B → πK decays. I discuss how to deal with electroweak-penguin contributions to these decays using flavour SU(3). With these, I show that the entire unitarity triangle can be extracted from measurements of B → πK decays. Finally, I examine the signals for new physics in these decays and the possibilities for measuring them. talk giv...

PURPOSE To report a peculiar curvilinear pigmentary lesion in the peripheral fundus in a rod-cone dystrophy. METHODS Observational case report. Fundus examination of a 57-year-old woman who was known to have a generalized rod-cone dystrophy since she was 8 years old. RESULTS The peripheral fundus examination revealed a curvilinear lesion which resembles a well-known finding associated with ...

Bardet-Biedl syndrome (BBS) is a rare autosomal recessive disorder with clinical and genetic heterogeneity. This syndrome was first described by Laurence and Moon in 1866 and additional cases were described by Bardet and Biedl between 1920 and 1922. The main features are obesity, polydactyly, pigmentary retinopathy, learning disabilities, various degrees of intellectual impairment, hypogonadism...

Pigmentary mosaicism is a term used to encompass all of these different types of pigmentary patterns. Among these mosaic patterns, there have been only a few reports of the phylloid presentation in the literature. On the other hand, autoimmune disorders can be associated with neurocutaneous markers and syndromes. A fifteen-year-old girl was presented for chronic diarrhea and abdominal pain. Her...
