Isolated central canal rupture of spinal dermoid: Report of two cases

We report two cases of lumbar spinal dermoid cysts with asymptomatic rupture and migration of free fat droplets into the central canal. No fatty droplets were seen within the lumbar subarachnoid space. The presence of fat droplets within the central canal is unusual because the central canal is rudimentary in adults. We suggest that hydromyelia secondary to tumour and specific tumour morphology might facilitate the selective rupture of dermoids into the central canal. We recommend a follow up of these patients to detect any possible intracranial migration of fat droplets and resultant complications.     

对陈香露白露片检验中有关问题的探讨

目的：探讨部颁标准陈香露片检验中存在的问题。方法：Ｅ和部颁标准和改进方法对陈香露片中的铋盐进行定性一定量、镁盐进行定性。结果：该片中的铋盐磺四鉴别反应。用稀硝酸代替盐酸做溶剂,呈正反应、镁盐氯化铵＝磷酸氢二钠鉴别反应,加氨试液后,析出的白色沉淀不足Ｍｇ（ＯＨ）２,而是Ｂｉ（ＯＨ）３,该深沉在氯化铵试液中不溶,干扰镁盐鉴别;铋盐含量测定项,用加抗坏血酸掩蔽剂的方法,排除了Ｆｅ＾３＋的干扰,使终点颜色     

Comparison of health‐related quality of life and emotional distress among Chinese cancer survivors

The purpose of this study is to compare health‐related quality of life (HRQoL) and emotional distress among diverse cancer survivors who had completed all treatment within the previous year. A convenience sample of 353 cancers survivors (lung, head and neck, breast and prostate cancers) were recruited to complete a survey, which consisted of (i) Hospital Anxiety and Depression Scales; (ii) Chinese version of the Functional Assessment of Cancer Therapy—General version; and (iii) demographic and clinical data. The HRQoL scores were similar among the four types of survivors. Mild anxiety and depression levels were reported, but no significant difference was noted. Younger females with financial burdens and uncertain prognosis were particularly associated with HRQoL and emotional distress. Further studies are essential to identify specific problems that cancer patients experience after cancer diagnosis that might lead to the early detection of those most at risk of ongoing problems.     

糖尿病的胃肠并发症

目前，随着糖尿病患者的增加，糖尿病胃肠并发症越来越常见，这些并发症及其症候通常是由胃肠运动异常引起，常与胃肠道神经病变相关。有研究表明，糖尿病自发神经病变与糖尿病的持续时间有关，但糖尿病控制及并发症的临床试验表明，1型糖尿病患者其神经和胃肠并发症与血糖控制不良有关，与患者持续时间并无必然联系。糖尿病引发的胃肠异常通常可见胃轻瘫、肠下垂（可导致腹泻、便秘和排便失禁）以及非酒精性脂肪肝。     

Migrating transient osteoporosis of the hip in a 30-year-old man

Transient osteoporosis of hip is a condition of unknown etiology, presenting as painful limping, and characterized by osteopenia of the involved joint without preexisting disease or immobilization. Most of the cases were reported in middle-aged men, and one-third of the cases develop in women in the third trimester of pregnancy. The hypothesis that this condition leads to avascular necrosis of the hip has been disproved by various reports and hence does not warrant any surgical interference. This is a self limiting condition, which needs regular follow-up. The authors report a case of migrating transient osteoporosis of the hip in a 30-year-old man successfully treated with antiresorptive treatment.
