Analysis of 1,620 basal cell carcinomas treated at the Cleveland Clinic Foundation from 1981 to 1983 confirms that the majority of basal cell carcinomas occur on the face and that the relative risk for recurrent tumor is high in certain locations, especially the nose. Alternately, tumors found on the neck/scalp, trunk, and arms have a low relative risk of recurrence when compared to all other anatomic locations. More primary and fewer recurrent tumors now presenting to our unit have been referred for Mohs surgery as primary therapy. This results in higher cure rates for treatment of all basal cell carcinoma.
SUMMARYThe mastitis caused by P. zopfii alga is a disease of highproducing, machine-milked dairy cows. It occurs worldwide in tropical and temperate climatic areas, and mostly appears sporadically in a therapy-resistant form. However, in poorly managed dairy herds it may be endemic, causing serious economic losses as a result of decreased milk quality and quantity and culling of infected animals. The biological properties of this pathogenic alga, the laboratory methods available for its isolation and identification, the pathological and clinical features of this form of mastitis, and the principles of its control are reviewed in this paper.
In the southeast of Hungary a sparrow hawk (Accipiter nisus) and several goshawk (Accipiter gentilis) fledglings succumbed to encephalitis manifesting as an acute neurological disease during the summers of 2004 and 2005. Both years the causative agent was identified as a lineage 2 West Nile virus. This is the first description of clinical, pathological and immunohistochemical findings of infection caused by a neuroinvasive, lineage 2 West Nile virus and the first evidence of its circulation in continental Europe.
In the last 2 years 223 cases of bovine mastitis caused by Prototheca zopfii infection were identified in 32 large-scale dairy herds. All of these farms were in Hungary, which has a continental type, temperate zone climate. Both the sporadic and epidemic forms of P. zopfii mastitis were observed. All the herds affected by the epidemic form had poor hygienic conditions and suffered from several managerial faults, but no specific predisposing factors could be identified. In almost all of the cases, the type II variant of this pathogen was isolated; however, the type III variant was isolated from three cows. The cows had a higher chance of new infection in the early weeks of lactation and in the summer. The P. zopfii infection usually resulted in a chronic subclinical, or mild clinical, inflammatory process in the udder, and was followed by a dramatic loss in milk production and a permanent increase in somatic cell count. The histopathological findings could be characterized as a progressive interstitial mastitis associated with alveolar atrophy. The self-recovery rate was very low.
Cutaneous benign neurofibromas are the most common skin manifestation of Von Recklinghausen neurofibromatosis (NF). An autosomal dominant disorder, NF has extraordinary clinical variability and multisystem involvement; many patients develop hundreds of cutaneous neurofibromas in a lifetime. This problem can easily and rapidly be treated using the CO2 laser with results equal to or better than excision. The procedure is very helpful for patients with large numbers of small- or medium-sized cutaneous neurofibromas.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
