Ichthyosis in two dogs.

Ichthyosis in 2 dogs was characterized by extreme hyperkeratosis on all or part of the skin and by extreme thickening of the digital and metapodial pads. The skin disorder closely resembled human lamellar ichthyosis, in which the histologic features include a thickened granular layer, mitotic figures, and dense collections of coarse keratohyaline granules. The disease was believed to be inherited, probably autosomal recessive, inasmuch as none of the parents was affected. Treatment of 1 dog with 5% lactic acid in hydrophilic ointment reduced the hyperkeratosis and decreased the shedding of scales.

Phaeohyphomycosis caused by Drechslera spicifera in a cat.

A slowly evolving subcutaneous mycosis in a 10-year-old domestic shorthair cat was found to be caused by Drechslera spicifera, the imperfect state of ascomycete Cochliobolus spicifer. The cat had circular, nodular, granulomatous lesions over its sternum. Scattered individual and small groups of septate hyphae and chlamydospores were found in histologic sections. Many of the hyphae also had bizarre dilatations. Most of the fungal elements were hyaline; a few, however, were dematiacious. Because the fungus was not organized into granules in tissue, the disease could not be classified as a mycetoma. The preferred name for infections of this type is phaeohyphomycosis.

Endoscopic forehead lift: the subperiosteal pulling stitch.

The endoscopic-assisted forehead lift has overtaken the coronal approach since 1992. One of the controversial points was the fixation of the flap in the elevated position. This article presents a simple pulling stitch using resorbable thread, subperiosteally. The mobile forehead after muscle resection is tracted up and back and fixed to the attached periosteum of the occipital bone. This fixation is strong for 3-4 months until the thread has melt. Long-term results of 3 years confirm the strength and longlasting of this subperiosteal pulling stitch (SPPS).
