Objective To evaluate the treatment of surgery and high-dose corticosteroid relevant factors to prognosis in traumatic optic neuropathy. Methods Forty patients(40 eyes) with traumatic optic neuropathy were enrolled.Optic nerve decompression using transcranial approaches,sinus endoscopy and orbital-ethmoidal sinus rout were performed in 14 patients.Eleven patients were treated with high-dose corticosteroids (5 cases with 1 mg/kg dexamethasone,6 cases with 30 mg/kg methylprednisolone) and 15 patients received nonspecific management chose by themselves.The outcomes of visual acuity in short term and final stage were compared between surgery,high-dose corticosteroid and nonspecific treatment.Multiple variable analysis was done to determine the factors affecting the outcome of visual acuity. Results No light perception were found in 19 cases (19 out of 44 cases,47.5%),whereas visual acuity was light perception to 0.02 in 12 cases (30.0%) and 0.05 or better in 9 cases (22.5%).The odds ratio of high-dose corticosteroid to nonspecific therapy was 2.96 (P=0.0125).The final visual acuity in patients treated with high-dose corticosteroid were better than other two groups (P=0.005,P=0.023,respectively).The short term (within 3 days) effective rate was higher in corticosteroid therapy group than operated group (P=0.024).No light perception following optic nerve trauma appeared to be more danger as 2.14 folds (P=0.0349) than those with light perception or better in term of final visual acuity outcome. Conclusions High-dose corticosteroid may be benefit to traumatic optic neuropathy.The treatment in traumatic optic neuropathy using optic nerve decompression needs to be determined.No light perception at initial is an important risk factor in the outcome.

ObjectiveTo explore the influence of norepinephrine on the prediction of fluid responsiveness by passive leg raising (PLR) during septic shock. MethodsForty-six septic shock patients in intensive care unit of Nanjing Drum Tower Hospital were prospectively observed from September to November 2012. Among which 36 septic shock patients were enrolled with a positive PLR test (defined by an increase in stroke volume index ≥10%). A PLR test was performed at baseline (PLR1). A second PLR test (PLR2) was performed at returning to supine position for 10 min and the dose of norepinephrine was increased to maintain MAP ≥65 mmHg for 20 min. The changes of heart rate(HR),mean arterial pressure(MAP),central venous pressure(CVP),cardiac index(CI),stroke volume index(SVI),index of systemic vascular resistance(SVRI),global end-diastolic volume index(GEDVI),and cardiac function index(CFI) were monitored by transpulmonary thermodilution technique (PiCCO). ResultsPLR1 significantly increased SVI by (20.54±9.63)%,CI by (20.57±9.89)%,MAP by (7.64±5.77)%,and CVP by (25.83±23.39)%. As the dose of norepinephrine increased,SVI was increased by (16.97±9.06)%,CI by (16.78±8.39)%,GEDVI by (9.08±4.47)%,MAP by (28.07±12.48)%,and CVP by (7.86±8.52)%. PLR2 increased SVI by (13.74±8.79)%,CI by (13.79±9.08)%,MAP by (2.93±5.06)%,and CVP by (13.36±14.74)%. The PLR2 and the dose increase of norepinephrine augmented SVI to a significantly lesser extent than the PLR1 performed at baseline (both P<0.05). However,SVI increased by <10% in 6 patients while the baseline PLR was positive in these patients. ConclusionIn septic patients with a positive PLR at baseline,norepinephrine increases cardiac preload and cardiac output and influences the fluid responsiveness.
To report a case of a 1-year-old female child admitted to the hospital with recurrent convulsions and diagnosed as West syndrome, also known as infantile spasms (IS). The child had been experiencing convulsions for 4 months prior to admission, characterized by forward head tilt and flexion of the limbs, with 8 ~ 10 episodes per day. After admission, West syndrome was identified by EEG and imaging evaluation, and adrenocorticotropic hormone (ACTH) shock therapy was started on day 5 of admission, supplemented with peripherally inserted central catheter (PICC), gastric protection, calcium and potassium supplementation and other supportive measures. During the course of treatment, the nursing team implemented meticulous monitoring and assessment to ensure that the child's vital signs were stabilized, and potential side effects were detected and treated in a timely manner. After 14 days of treatment, the child had no further spasticity episodes during 3 ~ 14 days, and was discharged from the hospital with continued oral hormone intake and regular follow-up. During the nursing process, the nursing staff provided psychological support and education to the child and her family to help the family understand the disease and enhance their ability to manage it. In addition, personalized nutritional support and monitoring were provided to ensure the healthy growth of the child. The successful management of this case not only enhanced the quality of clinical care, but also provided useful reference and inspiration for similar cases.
Objective To investigate the relationship among rats′ stress ulcer and gastric acid, prostaglandin (PGs) and adrenocorticotropin (ACTH) and to probe the pathogenesis, prophylaxis and therapy. Methods Rats′ stress ulcer model was made by cold water soaking and was properly treated with drugs such as hyoscine, dexamethasone, ranitidine and losec. The amount and pH of gastric juice, change of gastric mucosa and PGs and ACTH of blood were determined. Results After rats were fasted for 24 hours a little gastric juice was aspirated. After cold water soaking of rats gastric juice was increased with the pH decreased, there was gastric mucosal bleeding, blood PGs was decreased and ACTH was increased. These suggest that on stress gastric mucosa bleeding is related with decreased gastric juice pH, decreased PGs and increase ACTH.Conclusion To control stress ulcer, pH of gastric juice and amount of PGs should be increased. Losec can increase gastric juice pH, so losec is the first choice to control stress ulcer.
ObjectiveTo summarize the clinical and imaging features of hepatic adrenal rest tumor and to explore its tissue source, diagnosis, differential diagnosis and treatment.MethodsThe clinical data of patient with hepatic adrenal rest tumor in the West China Hospital of Sichuan University were analyzed retrospectively. The diagnostic methods of liver adrenal junction were summarized by consulting relevant literatures.ResultsThe patient was admitted to the hospital with right hepatic lesions. The preoperative imaging examination showed that it was the imaging features of hepatocellular carcinoma. The right hemihepatectomy was proposed. During the operation, it was found that the lesions were not from the liver, but from the retroperitoneum (The possibility of adrenal origin was very high). Then, the retroperitoneal occupying lesions was completely resected via urology surgery consultation. The pathological results showed that the tumor was adrenocortical carcinoma.ConclusionsIt is very difficult to accurately diagnose nature of hepatic adrenal rest tumor before operation only by results of cross-sectional imaging, especially for some adrenal tumor. It needs to fully be evaluated and even to perform multidisciplinary discussion if necessary for patients who have hepatic adrenal rest tumor before operation, so as to avoid misdiagnosis to a certain extent.
