Human epididymis protein 4 (HE4) levels inversely correlate with lung function improvement (delta FEV1) in cystic fibrosis patients receiving ivacaftor treatment

Background

We have recently shown that human epididymis protein 4 (HE4) levels correlate with the severity of cystic fibrosis (CF) lung disease. However, there are no data on how HE4 levels alter in patients receiving CFTR modulating therapy.

Contribution of ambulatory EEG recording (Medilog 9000) in a population of epileptics

Thirty-four epileptic patients, aged 9 to 36, were submitted to A/EEG between May 1987 and July 1988. All patients had a thorough clinical and EEG work-up including long-term conventional EEG, afternoon polygraphic sleep recording and, in some cases, full-night EEG and video monitoring. Patients were divided into 2 groups: group I included 19 patients (18 with symptomatic partial epilepsy (SPE) and 1 with idiopathic generalized epilepsy (IGE) in whom no seizure had ever been recorded in spite of EEG recordings averaging a total of 16 hrs 10 min, awake and asleep); group II included 15 subjects (6 with SPE, 5 with IGE, 3 with symptomatic GE and 1 with undetermined epilepsy) in whom one or several seizures had been recorded. A/EEG was performed in order to: 1) obtain better clinical and EEG characterization of seizures, 2) study the circadian distribution of seizures, 3) verify the efficacy of drug treatment and, 4) establish the epileptic or non-epileptic nature of some ictal events. The results of A/EEG were considered positive in 52.63% of group I patients and in 93.33% of group II patients. The authors discuss the specific advantages of A/EEG vs conventional EEG: recording of seizures with random occurrence, of seizures accompanied by falls, checking the remission of seizures.     

Comparison of the detection of subtle changes in myocardial regional systolic function using qualitative and semi-quantitative techniques.

PURPOSE: To evaluate qualitative wall motion assessment vs. quantitative wall thickening for the assessment of subtle changes in myocardial systolic function using cine MRI. METHODS: Cine MR images were obtained in 5 canines with a significant coronary artery stenosis and in 2 controls on a 1.5T scanner. Qualitative results were obtained using a numerical scoring system; quantitative analysis was performed using a semi-automatic segmentation program. The techniques were matched and compared using Spearman correlations. RESULTS: All correlations in the experimental group revealed significant but weak to moderate relationships between the qualitative and quantitative results (e.g., at-risk tissue rho = 0.363, p < 0.0001; remote tissue rho = 0.275, p = 0.0002), with each identifying changes in regional function that ensued following creation of the stenosis. Intra-observer variability was reasonable in both methods when repeat analysis on a subset of the data was performed, with both techniques showing a significant correlation between the repeated measurements (quantitative - rho = 0.52, p < 0.0001; qualitative - rho = 0.54, p < 0.0001). CONCLUSION: Both methods were able to detect very limited wall motion abnormalities present in the canines with significant stenosis and either method gives comparable results.     

含吡嗪酰胺抗痨治疗方案的肝毒性临床观察

对203例结核病患者用含吡嗪酰胺(PZA)方案治疗产生肝脏毒性进行分析,发生率为16.7％,较国内外报告的1～5％为高。5种含PZA方案肝毒性反应的发生率无差异(P>0.05),91％肝毒性发生在开始治疗两个月内,绝大多数预后良好。肝功能的GPT100单位以下者多在4周内恢复,100单位及以上者大多需8周以上恢复正常。如伴有黄疸个别可出现严重肝功能损害。提示含PZA方案一般较安全,但应严格掌握含PZA方案的适应症;用药早期要注意作好肝功能监测。     

对一宗入境二级放射货包的监测结果分析

汕头卫生检疫局空港处对汕头航空口岸—宗入境二级货包的监测过程及对有关运输工作人员作了放射知识问卷调查。从中发现。运输单位货物存放设施落后。有关工作人员放射卫生知识欠缺，对放射污染可能造成的危害缺乏正确的认识。为此，笔者提出了自己的看法，以期对放射监测工作的进一步完善提供参考。     

复治矽肺结核化疗效果观察

我们自１９８０～１９８８年对７９例复治矽肺结核进行化疗。其中绝大多数为慢性纤维化空洞性病例，均经细菌学证实，并由尘肺诊断组认定为矽肺合并结核。本组病例分别以ＫＭ、ＩＮＨ、ＲＦＰ、ＰＺＡ，或ＳＭ、ＩＮＨ、ＲＦＰ、ＥＢ联合，分两阶段治疗１８个月，获痰菌阴转７９．２％，其中ＫＨＲＺ与ＳＨＲＥ组分别为９３．９％与６８．２％（Ｐ＜０．０５）。自疗程结束追踪２～８年，其细菌复阳率分别为６．４５％和１０．０％（Ｐ＞０．１）。并对影响其过去治疗失败的原因及对策进行了讨论。
