CITIUS: an infrared-extreme ultraviolet light source for fundamental and applied ultrafast science.

We present the main features of CITIUS, a new light source for ultrafast science, generating tunable, intense, femtosecond pulses in the spectral range from infrared to extreme ultraviolet (XUV). The XUV pulses (about 10(5)-10(8) photons/pulse in the range 14-80 eV) are produced by laser-induced high-order harmonic generation in gas. This radiation is monochromatized by a time-preserving monochromator, also allowing one to work with high-resolution bandwidth selection.

Thyrotoxic hypokalemic periodic paralysis case report and review of the literature.

A rare complication of hyperthyroidism consists of sudden diffuse muscle weakness associated with severe hypokalemia. The clinical presentation is similar in most respects to familial periodic paralysis; however, the therapies proven to be effective differ in the two syndromes. A case of thyrotoxic hypokalemic periodic paralysis is presented and the literature is reviewed.

Juvenile Paget disease: life-long features of a mildly affected young woman.

Unusually mild Juvenile Paget Disease (JPD) was extensively investigated in a mentally retarded 21-year-old white woman. Progressive bowing deformitity of her lower limbs began at age 1 1/2 years. Nontraumatic fractures of both femora and both tibias occurred between ages 9 and 14 years.

Potential side effects of timolol therapy in the treatment of glaucoma.

The literature concerning the clinical and pharmacologic studies of systemically administered timolol in 2233 patients was reviewed. Side effects reported were correlated with dosage levels and estimated plasma levels. Most adverse effects occurred with levels much higher than would be expected after the topical use of timolol to control glaucoma.
