Her best corrected visual acuity (BCVA) was perception of light in her right eye and counting fingers close to face in her left eye. A slit lamp examination showed an anterior chamber (AC) reaction (1+) in both eyes with posterior synechia, a total cataract in her right eye, and pseudophakia in her left eye. The left fundus showed vitritis, vitreous membranes, chorioretinitis, multifocal areas of retinitis, and retinal vascular sheathing. A systemic examination showed extensive multifocal areas of tinea corporis on the hands and torso. Owing to the leukocytosis (22,000 cells/mm3), diagnostic vitrectomy was initially deferred and 100 mg of oral itraconazole was given twice a day for 3 months. The vitritis improved a little and her total white blood cell (WBC) count improved with treatment of the skin infection. Following a diagnostic vitrectomy later in her left eye, resolving areas of retinitis were seen. Complete resolution of eye inflammation was seen at the end of 6 weeks. At the 6-month follow-up, her BCVA was 6/18 in left eye and she was off oral steroids and methotrexate, with no recurrence of inflammation. We speculate a probable association between the ocular inflammation and extensive tinea corporis based on the therapeutic response to itraconazole.","PeriodicalId":19281,"journal":{"name":"Northern Journal of Applied Forestry","volume":"28 1","pages":"1174414"},"PeriodicalIF":0.0,"publicationDate":"2023-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11182326/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83437201","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigated silviculturally effective, operational solutions to implement early commercial thinning treatments. Comparisons between two wholetree (WT) and two cut-to-length (CTL) systems were made in terms of residual stem damage, retention of downed woody material, product utilization, and unit cost of production. Results show significantly more crop trees removed (P 0.030) and more high severity wound area per plot (P 0.011) for the WT systems. There was no difference in the number of stems wounded per plot at the high severity level between harvest methods (P 0.312). Harvest-generated and retained downed wood material volume averaged 511.9 and 205.6 ft/ac for CTL and WT plots, respectively. Round wood production was the same for CTL and WT plots (average 30 tons/ac), but more than four times more biomass was produced from the WT operations. Production costs were not significantly different between harvest methods due in part to high machine productivity and increased biomass production for the WT systems.","PeriodicalId":19281,"journal":{"name":"Northern Journal of Applied Forestry","volume":"30 1","pages":"149-155"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.5849/NJAF.13-016","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70978112","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An outbreak of shoot blight occurred in red pine sapling plantations across northern Wisconsin, northern Minnesota, and the Upper Peninsula of Michigan in 1993. We established monitoring plots in red pine sapling plantations severely affected by shoot blight in Michigan and Wisconsin to assess the influence of residual overstory red pine and the presence of Sirococcus and Diplodia shoot blights on disease severity and their long-term impact on tree survival and growth. Fourteen years after the initial outbreak, many red pine saplings had recovered from serious damage ( 1/3 of new shoots affected) that had occurred in a single outbreak year followed by lower levels of disease in subsequent years. However, the most severely affected trees sustained higher mortality and reduced growth. Forking or development of crooks of the main stem was common if terminal leaders were killed by shoot blight. Results from this study suggest that the impact of a shoot blight outbreak on red pine saplings largely depends on the presence or absence of an inoculum source in residual overstory trees, the species of pathogen present in the stand, and the initial disease severity.","PeriodicalId":19281,"journal":{"name":"Northern Journal of Applied Forestry","volume":"30 1","pages":"170-174"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.5849/NJAF.13-024","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70978161","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

First developed in Massachusetts, we report results of its application in New York. Administered to 496 randomly selected New York family forest landowners and 158 benchmark landowners who had received conservation training, results confirmed instrument validity and exposed low levels of awareness about conservation options among forest landowners in the study, especially concerning New York’s current-use tax program and conservation easements. Education level, ownership acreage, and location were associated with higher levels of conservation awareness. A comparative analysis between New York and Massachusetts forest landowners revealed significantly higher levels of conservation awareness for the New England state’s landowners. The CAI can be used to improve outreach efforts by targeting education toward the conservation options for which landowners have low levels of awareness. A high level of conservation awareness is the foundation for informed forest stewardship decisions.","PeriodicalId":19281,"journal":{"name":"Northern Journal of Applied Forestry","volume":"30 1","pages":"175-183"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.5849/NJAF.13-026","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70978171","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
