正确认识 合理对待:浅谈皮肤真菌病

近年来,常为人们关注的禽流感经全球不断研究证明是由早为人们熟悉的鸡瘟病病原——鸡瘟病毒的一个变种H5N1所引起,它不仅可引起鸡瘟病,还可引起人类禽流感。这种人禽共患的疾病统称“人兽(禽,畜)共患病(Zoonoses)”。随着SARS等突发公共卫生事件的出现,反生物恐怖已成为医学界参与的“无明确战线”项目。尤其是禽流感,因其高致病,高病死率更为人们所瞩目。很多真菌病     

子宫切除术患者的心理状态分析及干预

目的 分析子宫切除术患者的不同心理状态及实施护理干预的效果.方法 选择子宫切除术患者145例,随机分为对照组72例及干预组73例,干预组除行常规妇科腹部手术护理外,对患者不同心理状态进行调查分析及实施系统的护理干预;对照组则行常规护理.应用(SCL-90)进行问卷调查,国内常模调查作比较,数据处理采用t检验.比较2组心理负性情绪和生活质量.结果 干预组的心理负性情绪明显下降(P＜0.01).结论 医护人员应重视患者心理状态,积极进行护理干预能有效改变其负性心理,有利于患者的身心康复,提高生活质量.     

喉癌患者的健康教育需求调查分析

目的 了解喉癌患者对健康教育的需求并分析其原因.方法 采用自行设计的调查表对105例喉癌患者入院时、围手术期、出院前健康教育需求情况进行调查.结果 喉癌患者在入院时最希望了解自己目前病情及其治疗方案;围手术期时患者最关心的是:由自己决定是否手术,在术后能及时咨询和得到医护人员的指导;出院前费用情况及各项收费标准;患者出院后日常护理的健康需求具有多样性.结论 现有的健康教育模式需要不断改进,才能满足不同患者的健康需要.     

Relationship between effort–reward imbalance and hair cortisol concentration in female kindergarten teachers

Objective

The present study aims to investigate the relationship between effort–reward imbalance and hair cortisol concentration among teachers to examine whether hair cortisol can be a biomarker of chronic work stress.

Methods

Hair samples were collected from 39 female teachers from three kindergartens. Cortisol was extracted from the hair samples with methanol, and cortisol concentrations were measured with high performance liquid chromatography–tandem mass spectrometry. Work stress was measured using the effort–reward imbalance scale.

Results

The ratio of effort to reward showed significantly positive association with hair cortisol concentration.

Conclusion

The cortisol concentration in the system increases with the effort–reward imbalance. Measurement of hair cortisol can become a useful biomarker of chronic work stress.     

Primary alveolar soft part sarcoma arising from the cerebellopontine angle

Introduction

Alveolar soft part sarcoma (ASPS), a rare soft tissue malignant neoplasm, frequently metastasizes to the brain. However, primary intracranial ASPS is extremely rare. We present a case of primary intracranial ASPS arising from the cerebellopontine angle (CPA) without demonstrable systemic lesions.

Case report

An 11-year-old girl presented with a recurrent tumor in the right CPA after a partial resection and radiation therapy (RT). Near-total resection with a minimal tumor left in the jugular foramen was performed. The pathological diagnosis was ASPS. There was no evidence of primary extracranial tumors. She underwent adjuvant chemotherapy and gamma knife surgery. At 29 months after the second surgery, magnetic resonance imaging revealed multifocal enhancing lesions at the prepontine cistern, right CPA and medulla oblongata, despite intensive treatment. However, extracranial metastasis was not noted. This case suggested a poor outcome of primary intracranial ASPS, similar to extracranial ASPS.     

Usefulness of contrast enhanced FLAIR imaging for predicting the severity of meningitis

The aim of this study was to evaluate whether contrast enhanced fluid attenuated inversion recovery (CE-FLAIR) imaging can be used to predict the severity of meningitis based on leptomeningeal enhancement (LE) score and cerebrospinal fluid signal intensity (CSF-SI) on CE-FLAIR. We retrospectively analyzed data collected from 43 consecutive patients admitted to our hospital due to meningitis. Clinical factors including initial Glasgow Coma Scale (GCS) score, CSF glucose ratio, log CSF protein, log CSF WBC, and prognosis were evaluated. The LE score was semi-quantitatively scored, and we evaluated CSF-SI ratio at the interpeduncular or quadrigerminal cisterns on CE-FLAIR. We evaluated the differences in clinical variables, LE scores and CSF-SI ratios between the recovery and the complication group. We assessed the correlation between clinical variables, LE scores and CSF-SI ratios. The values of log CSF protein, CSF-SI ratio, and LE score were significantly higher in the complication group (p value <0.05). GCS score and CSF glucose ratio were significantly lower in the complication group (p value <0.01). The LE scores had significant negative correlation with GCS scores and CSF glucose ratios (p value <0.001). The LE score was significantly positively correlated with the value of log CSF protein and CSF-SI ratio (p value <0.01). The CSF-SI ratio was negatively correlated with GCS score and CSF glucose ratio (p value <0.01). The CSF-SI ratio was positively correlated with the value of log CSF protein (p value <0.05). Our results suggest that LE score and CSF-SI ratio are well correlated with clinical prognostic factors. We may predict the clinical severity of meningitis by using LE scores and CSF-SI ration on CE-FLAIR imaging.
