Isolated Anisocoria as a Presenting Stroke Code Symptom is Unlikely to Result in Alteplase Administration

Background

Acute stroke codes may be activated for anisocoria, but how often these codes lead to a final stroke diagnosis or alteplase treatment is unknown. The purpose of this study was to assess the frequency of anisocoria in stroke codes that ultimately resulted in alteplase administration.

Familial homozygous hypercholesterolemia: clinical and cardiovascular features in 18 patients

Homozygous familial hypercholesterolemia (HFH) is a very rare autosomal dominant disease characterized by accelerated severe atherosclerosis. We examined 18 patients from 9 families with HFH. The age range was 6-30 years (mean = 16 years). Male to female ratio was equal. All patients had huge, multiple tuberous xanthomas on the skin and tendons. Mean +/- standard deviation of plasma cholesterol, triglycerides, low-density lipoproteins (LDL), and high-density lipoproteins (HDL) cholesterol levels were 608 +/- 89, 122 +/- 39, 550 +/- 88, and 26 +/- 8 mg/dl, respectively. Five patients (28%) had angina pectoris, two sustained a myocardial infarction, and one died at the age of 15 years. Two-dimensional echocardiography demonstrated supravalvular aortic stenosis in 3 of the 13 patients (23%). Coronary arteriography performed in 11 patients demonstrated significant obstruction in 6 patients, 2 each with single-, double-, and triple-vessel disease. Left main stenosis was present in 3 patients (27%). Supravalvular aortic narrowing was demonstrated in 6 patients (54%) and was associated with a gradient in 2 (25 and 35 mmHg, respectively). Segmental contraction abnormalities were detected in 2 of the 11 patients (18%). It is concluded that coronary artery disease is prevalent in patients with HFH and, based on the data presented, we recommend the performance of noninvasive technique, coronary arteriography and supravalvular aortography at an early age to detect and to follow the progression of the disease.     

L-肌肽对大鼠硒性白内障的影响

Objective To explore the effect of L-canosine in preventing and treating rat cataract induced by sodium selenite. Methods This was an experimental study. Cataract was induced in the rats by sodium selenite. Rats were divided into 3 groups and each group has 3 ones. L-canosine eye drops (50 g/L or 20 g/L) and 0.9% normal saline were respectively instilled to the rat eye for 3 weeks and examined. L-canosine was added to the medium of cultured rat cataract lens at 1.00, 0.10 and 0.01 g/L for 1 week and then examined. Cataract lens were studied by using two-dimensional eletrophoresis. Results One week after instillation of L-canosine, the scores of rat cataract were 2.22±0.65, 2.39±0.98 and 2.83±0.38 in 50 g/L, 20 g/L L-canosine and control groups, respectively. The lesion in 50 g/l, L-canosine group was lighter than that of the control group. There was significant difference between these two groups (P=0.013). On the 2nd and 3rd weeks, there was no difference among these three groups. After 1 week for culturing cataract lens, there was no difference between these three groups. The results of two-dimensional eletrophoresis showed that the protein number was 182 and 161 in the L-carnosine and control groups, respectively. High molecular weight protein decreased and low molecular weight protein increased in L-carnosine group. Conclusions L-carnosine at 50 g/L could restrain the development of early stage rat cataract. L-camosine could modulate the rat lens protein in vitro, but could not affect lens cataract scores.

神经系统疾病患者血小板参数的变化及临床意义

目的 探讨神经系统疾病患者血小板参数的变化。方法 测定神经系统疾病患者血小板数(PLT)和平均血小板体积(MPV)，并与对照组作比较。结果 与对照组比较，脑梗死、椎-基底动脉供血不足患者PLT明显减少，MPV明显增大；脑出血组MPV、PLT均减少。结论 血小板参数的变化对神经系统疾病的诊断、预防和治疗有重要的参考价值。     

Dysphagia,an unrecognized handicap

The aim of this study was to examine whether esophageal dysphagia can be described as a handicap and to grade the severity of handicap as the discrepancy between the subject's own eating goals and his or her eating disability. The severity of the disability-goal-handicap (DGH) regarding dysphagia was expressed on a scale ranging from 0 to 48 points. Nineteen patients with dysphagia of differing causes were selected from a patient register at a laboratory for diagnostic procedures of the esophagus. The severity of handicap for the 19 patients was, on average, 33 points (range, 20–44). The DGH score correlated significantly with the patients' own evaluation of the severity of their dysphagia (p=0.008). The DGH scores did not differ markedly based on patient's sex, age, or cause of dysphagia. Patients who were operated upon because of dysphagia had significantly more points on the DGH scale prior to operation than patients who were not (p=0.001). Denial of dysphagia (N=18), concealment of dysphagia (N=18), and lack of confirmation by the patient's physician (N=15) were common but did not influence the severity of handicap as assessed by the DGH scale. It was shown that dysphagia affects all aspects of life as expressed by reduction in self-esteem (N=13), security (N=16), work capacity (N=8), exercise (N=7), and leisure time (N=6). Esophageal dysphagia may therefore be regarded as a handicap when assessed using the DGH code described in this study.
