Summary Confirmation was obtained of the occurrence in Italy in 1976 of an epizootic of classical swine influenza in pigs. Confirmation was based on the isolation of influenza virus strains showing a close antigenic relationship with both classical influenza A/Swine/ Iowa/30 (Hsw 1 N1) virus and A / New Jersey / 8 / 76 virus; a rise in antibody titer in sera obtained during the acute and convalescent stages of illness; and a high incidence of HI antibodies in tests with A / New Jersey virus (Hsw 1 N1) and a very low incidence in tests with influenza A/Victoria/3/75 (H3 N2) virus on 1330 sera from 46 farms in the province of Mantova (North Italy). Zusammenfassung Bericht über das Auftreten klassischer Schweineinfluenza in Italien im Jahre 1976 Das epizootische Auftreten klassischer Schweineinfluenza in Schweinen wurde in Italien bestätigt. Diese Bestätigung basiert auf den folgenden Ergebnissen: a) Isolierung von Influenzastämmen mit naher antigenetischer Verwandtschaft zu den klassischen Influenzastämmen A/Swine/Iowa/30 (HSwl/ N1) und A / New Jersey J 8 / 76. b) Anstieg der Antikörpertiter in Schweineseren während der akuten Krankheitsphase und in der Konvaleszenzphase. c) Häufiger Nachweis von Antikörpern im HAH‐Test gegen das A / New Jersey‐Virus (HSw1/N1) sowie sehr seltener Nachweis von Antikörpern gegen Influenza A/Victoria/3/75 (H3/N2) in 1330 Seren von 46 Farmen der Provinz Mantua/Norditalien.

Twenty-seven percent of eyes with laser programming errors ultimately lost one or more lines of CDVA. Patients who underwent surgical revision had better outcomes than those who did not. Many of the mistakes identified were likely avoidable had preventive measures been taken, such as strict adherence to patient verification protocol or rigorous rechecking of treatment parameters.

Categories of reasons for recommending LASIK to others were similar to reasons given by patients for seeking LASIK. Some patients who reported dissatisfaction with their vision said they would recommend LASIK, suggesting that recommendation of LASIK to others is not necessarily a measurement of the quality of a patient's vision after LASIK.

A mycoplasma strain, isolated from natural synovitis of guinea-fowl, was identified as Mycoplasma synoviae. In experimental infection this agent showed clear pathogenicity for guinea-fowl, and to a lesser degree for chickens. In guinea-fowl the strain was more likely to result in synovitis and amyloidosis when inoculated by the intravenous route and to produce sinusitis after intrasinusal inoculation.
