Seventeen children presenting with leucocoria were subjected to complete investigations. Careful A and B mode ultrasonography allowed us to make the correct diagnosis of retinoblastoma in 11 eyes of 9 patients, which was confirmed by histopathology or by response to radiotherapy. The diagnosis of retinoblastoma was not missed ultrasonographically in any of the eyes studied. The "V/W" configuration and absence of vascular pulsations on A mode; the "mixed" pattern and absence of choroidal excavation and orbital shadowing on B mode were found to be essential echographic features in characterizing the tumor and in differentiating it from other conditions including vitreous hemorrhage. The ultrasonographic features of early extraocular extension of retinoblastoma are discussed. Careful ultrasonic evaluation of leucocoria would seem to be invaluable in obviating the possibility of misdiagnosis in such problematic cases. 相似文献

Burkholderia pseudomallei in Environment of Adolescent Siblings with Melioidosis,Kerala, India, 2019

In 2019, Burkholderia pseudomallei was isolated from the backyard of 2 siblings with melioidosis in Kerala, India. This finding highlights the value of healthcare providers being aware of risk for melioidosis in febrile patients, of residents taking precautions when outside, and of increasing environmental surveillance for B. pseudomallei in this region. 相似文献

Background Two important limitations of the data regarding the outcomes of catheter ablation of atrial fibrillation (AF) are the short-term follow-up used in most published studies and the lack of single-procedure outcomes.Objective The objective was to report the long-term single-procedure outcomes at our center.Materials and methods The patient population was comprised of 200 consecutive patients who underwent ablation (133 men; age 56 ± 11 years). Atrial fibrillation was paroxysmal in 92 (46%). Success was defined as absence of symptomatic AF, off antiarrhythmic drug (AAD) after a single procedure.Results After a follow-up of 26 ± 11 months, the single-procedure long-term success rate was 28% with an additional 7% of patients demonstrating improvement. After including repeat procedures in 64 patients, the overall long-term success rate was 41% with 11% demonstrating improvement. Further subgroup analysis of 48 paroxysmal AF patients considered to be optimal candidates for the procedure, revealed a long-term success rate of 69% with an additional 4% demonstrating improvement. A major complication occurred in 7.9% of patients.Conclusion The results reveal that the long-term single-procedure success rate of catheter ablation of AF in a cohort of patients with predominantly non-paroxysmal AF is less than 40%. The inclusion of redo procedures resulted in an improvement in outcomes. A much higher success rate of 69% was achieved in patients with paroxysmal AF considered to be optimal candidates for this procedure. These results make it clear that further advances in the technique of catheter ablation of AF are needed to improve the safety and efficacy of this procedure. In order to be able to compare outcomes of various techniques in differing patient populations, we urge investigators to report long-term single procedure outcomes.This study was supported by The Norbert and Louise Grunwald Cardiac Arrhythmia Research Fund. 相似文献

AIM: To determine the risk factors for acute endophthalmitis after cataract extraction in a tertiary care centre in India.
METHODS: We performed a nested case control study within a retrospective cohort. The surgical records of all patients with clinically diagnosed endophthalmitis within one month after cataract surgery, performed between January 2006 and December 2009, were reviewed. These were compared with randomly selected age and gender-matched controls, from patients having routine cataract surgery within ±1wk of the endophthalmitis case. Univariable and multivariable analysis were performed to identify risk factors for endophthalmitis.
RESULTS: Of the total 33 856 cataract surgeries performed during this period, there were 57 cases of postoperative acute endophthalmitis that met our study criteria. Thus, the overall incidence of endophthalmitis in our cohort was 1.6 per 1000 cataract extractions performed. Mean age of cases was 55.9y (SD: 10.9y) and for controls was 55.6y (SD: 9.8y). Thirty-five cases (61.4%) and 133 controls (59.6%) were males. Median time of onset of endophthalmitis was 4d (IQR 2-9d; range: 1-30d). Thirty-nine cases (68.4%) presented within 7d and 27 cases (47.4%) were culture positive. Two hundred and twenty-three age and gender matched controls were selected. In multivariate analysis, endophthalmitis was associated with posterior capsular rupture (PCR) during surgery (OR 6.98, 95%CI: 2.22-21.98), phacoemulsification via scleral incision with a foldable intraocular lens (IOL) implantation (OR 3.02, 95%CI: 1.13-8.04) and ocular co-morbidity (OR 2.32, 95%CI: 1.11-4.87).
CONCLUSION: PCR, presence of ocular co-morbidity, and phacoemulsification via scleral incision with foldable-IOL were found to be independent risk factors for acute endophthalmitis. 相似文献

Metabolic syndrome is a cluster of risk factors for cardiovascular disease that include obesity, atherogenic dyslipidemia, raised blood pressure, and insulin resistance. The growing trend of obesity is associated with increased prevalence of metabolic syndrome. Optimizing diet and exercise are still the leading therapy for controlling the metabolic syndrome. Based on the current evidence, further emphasis should be placed on aggressive management of other metabolic risk factors such as high blood pressure and dyslipidemia. 相似文献

We report three cases of Vitamin B12 deficiency with symmetrical posterior spinal cord lesions and discuss the differential diagnosis, some of which are not well known. Because the degree of resolution of the clinical symptoms in subacute combined degeneration depends on early detection, MRI findings should not be missed. 相似文献
