ABSTRACT
Objective To explore the clinical features,primary lesions and prognosis of optic nerve metastases.Methods Seven patients (11 eyes) with optic nerve metastatic tumor diagnosed by the examinations of ophthalmology,laboratory and pathology in Chinese PLA General Hospital from April 2015 to September 2017 were included in this study.All patients underwent BCVA,flash VEP,OCT,orbital MRI,serum tumor marker,cerebral spinal fluid detection and PET-CT.Histopathological examination of primary or near superficial metastases was performed.The follow-up period was ranged from 16 to 44 months,with the mean of 23.0 ± 10.9 months.The clinical characteristics,primary tumor,imaging features,treatment and clinical prognosis in the patients were analyzed.Results Among 7 patients,there were 5 males and 2 females,with the mean age of 53.90± 14.99 years;3 patients with unilateral optic nerve involvement,4 patients with bilateral optic nerve involvement;5 patients (71.4％) first diagnosed in ophthalmology.Five patients (45.5％) were misdiagnosed as optic neuritis,optic disc edema in 6 eyes (54.5％).All of them appear loss of visual acuity,including 8 eyes (72.7％) with BCVA＜ 0.1,2 eyes (18.2％) with BCVA 0.1-0.5,1 eye (9.1％) with BCVA ＞ 0.5.MRI results show that 1 patient with intraorbital segment,1 patient with internal segment of optic canal,4patients with intracranial segment,1 patient with intracranial segment and optic chiasma involved simultaneously,4 patients involving surrounding tissue.There were 4 patients (57.1％) with lung cancer,2 patients (28.6％) with kidney cancer,1 patient (14.3％) with gastric cance;6 patients (85.7％) with metastasis from other sites,2 patients with brain metastasis (1 patient with meningitis carcinomatosa).There were 2 patients (28.6％) with previous primary cancer surgery.After diagnosis,1 patient received chemotherapy,1 patient received radiotherapy,5 patients gave up treatment.At the end of follow-up,1 patient (1 eye) of chemotherapy with BCVA increased by 2 line;1 patient (2 eyes) of radiotherapy with no change in BCVA;of the 5 patients who gave up treatment,1 patient died of disease,1 patient lost follow-up,and 3 patients (4 eyes) had no change in BCVA.Conclusions With atypically clinical manifestations,the optic nerve metastases easily misdiagnosed as optic neuritis,and with poor therapeutic effect.Primary lesions are mostly found in lung cancer.
ABSTRACT
Objective To explore the effect of continuing care on the intermittent catheterization compliance of patients with neurogenic bladder. Methods From January to December, 2015, 60 patients with neurogenic bladder after spinal cord injury receiving intermittent cathe-terization were randomly assigned to control group (n=30) and intervention group (n=30). The control group received routine discharge in-struction, while the intervention group received continuing care in addition. The intermittent catheterization compliance, residual urine vol-ume, urinary tract infection and quality of life were assessed at discharge and three months after intervention. Results After intervention, the intermittent catheterization compliance was better in the intervention group than in the control group (χ2=7.500, P=0.006). The residual urine volume significantly decreased in both groups (t>12.040, P4.572, P5.505, P<0.001). Con-clusion Continuing care could improve the intermittent catheterization compliance, reduce the residual urine volume and the urinary tract in-fection rate, and improve the quality of life in patients with neurogenic bladder after discharge.
