Lymphoproliferative disease of the ocular adnexa: A clinical and pathologic study with statistical analysis of 69 patients

Purpose: To evaluate the clinical features, treatment, and outcomes of a cohort of patients with ocular adnexal lymphoproliferative disease classified according to the World Health Organization modification of the Revised European-American Classification of Lymphoid neoplasms and to perform a robust statistical analysis of these data. Methods: Sixty-nine cases of ocular adnexal lymphoproliferative disease, seen in a tertiary referral center from 1992 to 2003, were included in the study. Lesions were classified by using the World Health Organization modification of the Revised European-American Classification of Lymphoid neoplasms classification. Outcome variables included disease-specific Survival, relapse-free survival, local control, and distant control. Results: Stage IV disease at presentation, aggressive lymphoma histology, the presence of prior or concurrent systemic lymphoma at presentation, and bilateral adnexal disease were significant predictors for reduced disease-specific survival, local control, and distant control. Multivariate analysis found that aggressive histology and bilateral adnexal disease had significantly reduced disease-specific Survival. Conclusions: The typical presentation of adnexal lymphoproliferative disease is with a painless mass, swelling, or proptosis; however, pain and inflammation occurred in 20% and 30% of patients, respectively. Stage at presentation, tumor histology, primary or secondary status, and whether the process was unilateral or bilateral were significant variables for disease outcome. In this study, distant spread of lymphoma was lower in patients who received greater than 20 Gy of orbital radiotherapy.

Genetic uniformity of international isolates of Leifsonia xyli subsp xyli, causal agent of ratoon stunting disease of sugarcane

An international collection of the sugarcane ratoon stunting disease pathogen, Leifsonia xyli subsp. xyli, was analysed to assess genetic diversity. DNA fingerprinting using BOX primers was performed on 105 isolates, comprising 65 Australian isolates and an additional 40 isolates from Indonesia (n = 8), Japan (n = 1), USA (n = 3), Brazil (n = 2), Mali (n = 2), Zimbabwe (n = 13), South Africa (n = 9) and Reunion (n = 2). Sixty-two of these isolates were also screened using ERIC primers. No variation was found among any of the isolates. The intergenic spacer (IGS) region of the ribosomal RNA genes from 54 isolates was screened for sequence variation using single-stranded conformational polymorphism (SSCP), but none was observed. Direct sequencing of the IGS from a subset of nine isolates, representing all of the countries sampled in this study, confirmed the results of the SSCP analysis. Likewise, no sequence variation was found in the 16S ribosomal RNA genes of the same subset. Four Colombian isolates from sugarcane, morphologically similar to L. xyli subsp. xyli, were putatively shown to be an undescribed Agrococcus species of unknown pathogenicity. The lack of genetic variation among L. xyli subsp. xyli isolates, independent of time of sampling, cultivar of isolation, or country of origin, suggests the worldwide spread of a single pathogenic clone, and further suggests that sugarcane cultivars resistant to ratoon stunting disease in one area should retain this property in other regions.

Application of mint and cinamon against Fusarium disease of winter wheat

In our study the application of mint species (spearmint, peppermint ‘Mitcham’ and peppermint ‘Mexian’) and cinnamon was investigated against Fusarium head blight of winter wheat in vitro and in vivo. The effect of crude drugs and the aqueous extract of mint, and the effect of essential oils of mint and cinnamon on mycelial growth were evaluated in lab. On artificial media the crude drug showed higher inhibition than aqueous plant extracts. Cinnamon and spearmint oils e.ectively inhibited mycelia growth. In field trial artificially inoculated winter wheat was treated with the in vitro effective oils under small-plot conditions. The disease incidence was most inhibited by cinnamon oil, applied curative. According to our results the essential oil of cinnamon can be an appropriate candidate for the research of alternative disease control.

Black band disease of corals: Ecology and physiology of Phormidium corallyticum

Black band disease of corals consists of a microbial community dominated by the cyanobacteriurn Phormidium corallyticum. The disease primarily affects reef-framework coral species, Active black band disease continually opens up new substrate in reef environments by destroying coral tissue as the disease line advances across the surface of infected colonies. A field study was carried out to determine the abundance and distribution of black band disease on the reef building corals in the Florida Keys. During July of 1992 and 1993, up to 0.72% of coral colonies were infected with black band disease. Analysis of the distribution showed that the disease was clumped. Seasonal patters varied, with some coral colonies infected year round, others exhibiting reinfection from summer 1992 to summer 1993, and some colonies infected for one year only. Statistical analysis of black band disease incidence in relation to various environmental parameters revealed that black band disease was associated with relatively shallow water depths, higher temperatures, elevated nitrite levels, and decreased ortho-phosphate levels. Additional field studies determined recovery of scleractinian coral colonies damaged or killed through the activities of black band disease over a five-year period. These studies determined if the newly exposed substrate was recolonized through scleractinian recruitment, if there was overgrowth of the damaged areas by the formerly diseased colony, or if coral tissue destruction continued after the cessation of black band disease activity. Tissue loss continued on all coral colonies with only one colony exhibiting new tissue growth. The majority of recolonization was by non-reef-framework corals and octocorallians, limited recruitment by framework species was observed. Physiological studies of P. corallyticum were carried out to investigate the photosynthetic capacity of this cyanobacterium, and to determine if this species has the ability to fix dinitrogen. The results of this research demonstrated that P. corallyticum reaches maximum photosynthetic rates at very low light intensities (27.9 μE/m/sec), and that P. corallyticum is able to carry out oxygenic photosynthesis in the presence of sulfide, an ability that is uncommon in prokaryotic organisms. ^

Prevalence and Incidence of Black Band Disease of Scleractinian Corals in the Kepulauan Seribu Region of Indonesia

Black band disease (BBD) is the oldest recognised disease associated with scleractinian corals. However, despite this, few BBD surveys have been conducted in the Indonesian archipelago, one of the world’s hot spots for coral diversity. In this study, we show that BBD was recorded in the reefs of Kepulauan Seribu, Indonesia, at the time of surveying. The disease was found to mainly infect corals of the genus Montipora. In some instances, upwards of 177 colonies (31.64%) were found to be infected at specific sites. Prevalence of the disease ranged from 0.31% to 31.64% of Montipora sp. colonies throughout the archipelago. Although BBD was found at all sites, lower frequencies were
associated with sites closest to the mainland (17.99 km), as well as those that were furthest away (63.65 km). Despite there being no linear relationship between distance from major population centers and BBD incidence, high incidences of this disease were associated with sites characterized by higher
levels of light intensity. Furthermore, surveys revealed that outbreaks peaked during the transitional period between the dry and rainy seasons. Therefore, we suggest that future surveys for disease prevalence in this region of Indonesia should focus on these transitory periods.
