To study the morphology of the adrenal glands of patients with Addison's disease an ultrasound and a computed tomographic scan of the adrenal glands were performed in 28 patients with Addison's disease. Thirteen patients had bilateral, asymmetric adrenal enlargement. In six of these patients, areas of necrosis and calcification were also seen. Six patients had atrophic glands with calcification and nine patients had normal/atrophic glands without calcification. After instituting appropriate treatment, computed tomography (CT) was repeated between 6 months and 3 years later in 10 of the 13 patients with adrenal enlargement. A reduction in gland size was noted in all patients and one had functional recovery. We conclude that the appearance of the adrenal glands on CT depends not only on the nature of the underlying disease but also on the duration of the illness and the type of treatment.
A significant number of patients after initial recovery from COVID-19 continue to experience lingering symptoms of the disease that may last for weeks or even months. Lungs being the most commonly affected organ by COVID-19, bear the major brunt of the disease and thus it is imperative to be aware of the evolution of the pulmonary parenchymal changes over time. CT chest is the imaging modality of choice to evaluate post-COVID lungs. Persistent ground-glass opacities, septal thickening and parenchymal bands, crazy-paving, traction bronchiectasis and consolidation constitute the commonly encountered imaging patterns seen on CT in post COVID-19 lungs. Few vulnerable patients can develop lung fibrosis and show honeycombing on CT. Additionally, many complications like superadded infections (bacterial and fungal), pulmonary thromboembolism and pseudoaneurysm formation are also being reported. In the present pictorial review, we have tried to show the entire CT spectrum of sequelae of COVID-19 pneumonia and commonly associated infections and vascular complications.
Sugarcane (Saccharum spp.) successive planting causes 25-30% yield reduction in comparison to fallow or rice rotation planting in a three-year production cycle on Florida Histosols. Field experiments were established to manage the yield losses associated with successive planting through nitrogen fertilization and seed piece application of fungicides in plant and first ratoon crops each at two sites. Nitrogen fertilization treatments included 0 (N 0 ), 50 (N 50 ), and 100 (N 100 ) kg ha −1 applied in furrows at the time of planting, and one split application (N 50+50 ) with 50 kg ha −1 applied at planting and 50 kg ha −1 applied at 90 days after planting as side-dress. Fungicides treatments were mancozeb at 2.5 kg a.i. (active ingredient) ha −1 , mefenoxam at 0.57 kg a.i. ha −1 , and azoxystrobin at 0.30 kg a.i. ha −1 applied to seed cane pieces laid in the furrows at planting. Nitrogen fertilization showed increasing trends of the tiller and millable stalks production in plant and ratoon crops. N response varied with the time of ratooning. Overall, N 50+50 produced greater tons of cane per hectare (TCH) and tons of sucrose per hectare (TSH) compared to other N treatments in plant crop and late season ratoon crop (ratooned in March). N 100 treatment enhanced tillering and TCH in December ratooned crop. In 2016 plant crop, mefenoxam produced higher TCH than others, but no carryover effects were observed in ratoon crops. Both nitrogen fertilization and fungicides seem to be promising cultural practices to minimize yield losses in successive sugarcane planting in Histosols.
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.
