| • | Urgent Cardiac Surgery in a Patient with a Remote History of Heparin-Induced Thrombocytopenia: Use of the Anti-PF4/Heparin ELISA Confirmatory Test |
|
The use of established heparin protocols when heparin-induced thrombocytopenia (HIT) antibodies are negative is currently recommended for the management of patients with previous HIT who require cardiac surgery. Routine preoperative testing for HIT antibodies using an anti-PF4/heparin enzyme-linked immunosorbent assay (ELISA) introduces the problem of detecting nonpathogenic HIT antibodies, which can lead to a false diagnosis of the presence of platelet-activating antibodies. Our case report demonstrates the clinical utility of a newer confirmatory procedure performed using high dose heparin. We use this procedure in situations in which pretest probability is low (remote HIT) and the anti-PF4/heparin ELISA test results are weak to moderately positive (absorbance 0.4-1.0). |

| • | Effect of Enhanced UV-B Radiation on Reniform Nematode(Rotylenchus reniformis Linford and Oliveira) Populations in Cotton (Gossypium hirsutum L.) |
| To understand the effects of increased UV-B radiation on reniform nematode (Rotylenchus reniformis Linford and Oliveira) populations, cotton (Gossypium hirsutum L.) plants were exposed to three levels of UV-B radiation [0 (control), 6 and 12 kJ m-2 day-1] in a glasshouse from emergence to early square stage. At each UV-B treatment, four populations [0 (N0), 2500 (N2500), 5000 (N5000) and 7500 (N7500)] of reniform nematodes were incorporated into the sterilized rooting medium. Plant growth, development, photosynthetic parameters, pigments, phenolics and the number of eggs and nematode numbers in the rooting medium were recorded at the end of the experiment, 40 DAS. Even though, UV-B radiation did not significantly affect plant growth and development, it did significantly increase leaf and root phenolic concentrations. UV-B treatments significantly decreased both the egg and nematode numbers in all the nematode population treatments. Significant negative correlation was found between cotton leaf phenolic concentration and egg (slope = -69.4; R2 = 0.72) and nematode (slope = 103; R2 = 0.53) numbers. Similarly, root phenolics also showed negative correlation with egg (slope = -3184; R2 = 0.26) and nematode numbers (slope = -5857; R2 = 0.30). Therefore, current and projected UV-B radiation levels may have an important regulatory influence on nematode populations. | |
