A careful air management strategy successfully prevented pupil block in eyes that developed full air fill. DMEK-only procedures were more likely to require air removal than those combined with cataract surgery, which suggests that decreased zonular flexibility may prevent the air bubble from taking a more spherical shape and more easily allow occlusion of iridotomy.
This study demonstrates the substantial rate of rejection episodes that can be induced by corneal stroma in DALK and suggests that postoperative topical corticosteroids should be continued longer than the study's 7-week median and that young African Americans need higher-dose, longer-duration topical corticosteroids. The association between the side-cut method and rejection risk merits further investigation.
Donor-derived infections (DDIs) are a very rare but potentially devastating complication of solid organ transplantation. Here we present a cluster of proven donor-derived cryptococcal infection in the kidney, liver, and lung recipients from a single donor. Remarkably, the onset of illness in the kidney and liver recipients occurred more than 8-12 weeks after transplantation, which is beyond the incubation period previously reported for donor-derived cryptococcosis. DDI should always be considered in the differential diagnosis of transplant recipients admitted with febrile illness, even when presenting beyond the first month post-transplant. Communication between reference laboratories, transplant centers, and organ procurement organizations is critical to improve outcomes.
Prevalencia y factores asociados a sobrepeso y obesidad infantil en escuelas públicas y privadas de Tegucigalpa, Honduras Prevalence of pediatric overweight and obesity and associated factors in public and private schools in Tegucigalpa, Honduras ABSTRACT Objective: To compare the factors associated with overweight and obesity in children from public and private schools in the Kennedy colony, Tegucigalpa, Honduras. Materials and methods. We studied 357 schoolchildren between 6 and 11 years old. A survey was used to assess nutrition, food frequency, eating habits and practices, and physical activity. Students with overweight and obesity secondary to a basic pathology were excluded. The information was analyzed using Epi-info. We conducted a univariate and multivariate analyzes. Results: We found that 18% of the students were obese and 18% were overweight. Students from private schools were more frequently overweight and obese (46.3%) than those in public schools (33.2%). Fifty-three percent of public school students and 36.3% of private schools consumed homemade snacks. Over half (58.5%) of public school students and 68.7% of private schools reported doing some kind of outdoor physical activity. Conclusion: Childhood overweight and obesity are prevalent health problems. Private school students, in our sample, were more overweight and obese than public school students. Physical activity performed by school children in public and private schools was adequate in most cases.
In the era of PCV7, the incidence of pneumonia in infants younger than 36 months with high FWS and WBC count greater than 20 x 10(9)/L seems to be lower than that previously reported. However, this is not a uniform group because the incidence of pneumonia increases in infants older than 12 months and with higher ANC and serum CRP level.
Purpose. To describe a case of postoperative scleritis caused by a novel strain of Nocardia resistant to linezolid and trimethoprim-sulfamethoxazole (TMP-SMX).
Methods. Case report of a patient with microbiologically proven scleritis due to Nocardia asteroides. Results. The patient presented with pain, redness, and nodules on the sclera three months following pterygium excision with mitomycin C and amniotic membrane placement. As no response was noted with empiric treatment for bacterial scleritis, debridement was performed. The cytopathology report showed gram positive filamentous bacteria. A presumptive diagnosis of Nocardia scleritis was made and therapy was initiated based on a literature review on treatments for Nocardia infections. Cultures returned growing Nocardia asteroides. Antibiotic sensitivity testing revealed resistance to linezolid and TMP-SMX which are the traditional drugs of choice for Nocardia. The patient was treated with amikacin and imipenem as well as extensive debridement with pedicle grafts. The patient's scleritis resolved with a good visual outcome. Conclusions. Cultures should be obtained in all cases of necrotizing scleritis in patients with a recent history of conjunctival surgery to rule out unusual organisms such as Nocardia. Although literature states that resistance to linezolid and TMP-SMX is rare in Nocardia, sensitivity testing can be useful in unresponsive cases.
The effect of ultraviolet light irradiation (254 nm) on both the viability and the aflatoxin-producing ability of the fungus Aspergillus parasiticus NRRL 2999, a good aflatoxin-producing strain, was studied. This strain showed noticeable resistance and irradiation for more than 10 min was necessary to reduce survival to under 10%, while the white mutants were more susceptible (5 min of irradiation reduced survival to under 1%). Induction of mutants with complete loss of aflatoxigenicity was rare and only 3 of the 1463 survivors tested were aflatoxinless.
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.
