A Very Long-term Longitudinal Study on the Evolution and Clinical Outcomes of Persistent Iatrogenic Atrial Septal Defect After Cryoballoon Ablation

Background

Persistent iatrogenic atrial septal defect (iASD) is a common but poorly characterized complication after cryoballoon (CB) pulmonary vein isolation (PVI) procedures. We therefore investigate its prevalence, evolution, risk factors, and clinical outcomes in a prospective longitudinal study.

Features of pediatric head injury in Hong Kong

Head injury in children causes special concern in most communities. From 1989 to 1994, 2,785 children younger than 16 years old were admitted to our neurosurgical service because of head injury. Fall from a height was the major cause of head injury leading to admission in infants and children in preschool age groups, whereas traffic-related or bicycle-related accidents were more likely to be the cause of head injury for those aged 11–15 years. In all age groups there was a male preponderance. The overall mortality was 0.6%. Traffic-ralated accidents caused more severe injury and accounted for 67% of all fatalities. For patients under 6 years old, about 40% of head injuries occurred at home. Preventive measures for pediatric head injury in Hong Kong are suggested.     

Attitudes towards mental illness: testing the contact hypothesis among Chinese student nurses in Hong Kong

This study investigated whether previous contact with mental illness affected the attitudes to mental illness (AMI) of general student nurses in Hong Kong — the contact hypothesis. We employed a quasi-experimental design. We compared the attitudes to mental illness of students who had previous contact with mental illness through having taken a psychiatric secondment with those who had not taken a psychiatric secondment. Also, we compared the AMI of: students who had taken other courses related to mental illness with those who had not; those who had a family history of mental illness with those who had not; and those who lived with a mentally ill relative with those who did not. We found that previous contact with mental illness had no significant effect on the attitudes to mental illness of the students. In other words our findings do not support the contact hypothesis. Our sample expressed positive general attitudes to mental illness when presented with general issues about mental illness. However, their attitudes were less positive when presented with specific issues about mental illness that might impinge upon their daily lives. We discuss the implications of these findings for mental health nursing practice, education and research.     

Practice of orthokeratology by a group of contact lens practitioners in Hong Kong

Purpose: The aim of the study was to provide information about the characteristics of three main types of orthokeratology (ortho‐k) lenses used in Hong Kong and to report on their performance based on the clinical impressions of a group of ortho‐k practitioners. Method: Twelve ortho‐k practitioners were interviewed between 1 March and 30 June 2001. Results: Most ortho‐k lenses were ordered from three manufacturers: DreimLens, Fargo and Contex. The median maximum myopia reduction reported for DreimLens, Contex and Fargo lenses were 6.25 D, 6.00 D and 4.50 D respectively. The time to reduce myopia by up to 4.00 D could be up to three weeks for Contex and DreimLens and up to four weeks for Fargo. For reduction of myopia by up to 4.00 D, the treatment usually required only one or two lenses per eye for all three types of lenses. The incidence of lens binding and lens tightening after achieving the optimal reduction was reported to be higher with the DreimLens design. Good centration, less lens binding, relatively lower incidence of complications and lens tightening after achieving the optimal reduction were reported with the Fargo lenses. Conclusions: DreimLens tended to be more effective for myopia reduction. However, some practitioners were concerned with the aggressiveness of myopia reduction using this lens design and the higher potential for ocular complications. Selection of the lens design is dependent on various factors, in particular, practitioners need to be comfortable with the design they choose and to consider the needs of their patients and the final goal of the treatment.     

废弃物处理——一个刻不容缓的问题

介绍了香港环保署通过１０年努力的完整的固体废弃物收运，处理及处置系统，以及他们为实现废弃物减量化和资源化所采取的策略与行动。由此提出上海浦东新区在固体废弃物管理和环卫设施建设上应加强关注；逐步按规划实施；采用多种形式设计，建造，营运环卫设施以及开展全方位宣传教育活动的建议。     

千捶膏配合生肌玉红膏治疗感染性伤面的临床观察

我院多年来应用千捶膏和生肌玉红膏治疗感染性伤面。千捶膏用于去腐,生肌玉红膏用于生新。据我们观察二药有较强的抗感染作用,尤其有抗绿脓感染作用。应用千捶膏可以较快地达到脱腐作用,应用生肌玉红膏可以促进肉芽增生,达到伤面早期愈合,值得推广。     

香港与澳门中小学学校辅导发展的比较

目的 探讨香港与澳门两地中小学学校辅导的发展，就辅导工作的内容、开展情况、辅导人员在建设上的差别以及发展速度相异的原因等方面作分析。方法 本研究以香港及澳门中小学的学校辅导员／社工为调查对象，利用自编问卷方式进行调查．结果 （1）两地的辅导员都一致认为，通过学校辅导服务可以帮助中学生建立良好的社交行为及人际关系，（2）两地的中小学都在帮助学生更好地接纳他人及尊重他人这个项目上都做得较好；（3）两地的中小学校辅导的目标不再是以处理学生的偏差行为为主，转而注重学生的个人潜能发展；（4）就课堂辅导活动开展的情况来看，香港在班级辅导、全年级辅导及全校性辅导方面都做得比较好，而澳门的全校性辅导通有待加强。至于课堂以外的辅导活动，两地均以个别晤谈，团体辅导、心理卫生讲座以及工作坊等方式开展辅导活动为多。（5）在持介制度上，香港中小学都做得比较完善；（6）咨询服务方面，香港小学做得较多，而澳门则是中学做得较多；（7）新生适应服务方面，香港较澳门做得较多；（8）香港的学校比澳门学校更多地与其它机构共同合辩小区教育；（9）香港及澳门的中学辅导员主要是学校自聘／校内编制，两地的中学社工主要是由政府资助民间志愿机构派驻。香港的小学导员以学校自聘／校内编制和政府派驻为主，香港的小学社工以政府直接派驻为多；澳门的小学辅导员为政府派驻，小学社工则由政府资助民间志愿机构派驻为多。（10）对于两地学校辅导人员学历的比较，香港中学及小学专职辅导贝、专职社工的学历均较澳门为高．结论 两地在学校辅导目标上比较一致；两地均建立了发展辅导为主，预防辅导及治疗辅导并重的辅导模式；家庭问题及人际关系问题为两地中小学生的困扰问题；两地的学校辅导活动呈现一个多元化的局面，但香港较澳门丰富；澳门需要建立完善的转介机构。     

Wheezing in Chinese schoolchildren: disease severity distribution and management practices, a community-based study in Hong Kong and Guangzhou

BACKGROUND: Asthma is a common chronic disease and information on its management practices at the community level is helpful in identifying problems and improving asthma care. OBJECTIVE: To assess the severity status and management of the asthma symptom of wheeze of children at the community level in Hong Kong (HK) and Guangzhou (GZ). METHODS: Cross-sectional study of children aged 10 years using the International Study of Asthma and Allergic disease in Childhood (ISAAC Phase II protocol). Asthma management and lung function were assessed in 178 (98 from HK and 80 from GZ) randomly selected children with wheeze over the past 12 months. RESULTS: Eighty-three percent, 11%, 6% and 0% of children suffered from intermittent, mild persistent, moderate persistent and severe persistent asthma, respectively, according to the frequency of their symptoms. Addition of spirometric parameter only changed the asthma severity classification in 2.8% of children. Medications were used by 30.6% and 71.3% of children for wheeze in HK and GZ, respectively. In HK, inhaled beta(2)-agonist (73.3% among the drug users) was the commonest medication used followed by inhaled corticosteroid (ICS) (23.3%). In GZ, inhaled beta(2)-agonist was used by 75.4% of children, but use of ICS (26.3%), oral beta(2)-agonist (26.3%), oral theophylline (45.6%), oral ketotifen (36.8%) and oral steroid (35.1%) were also common. ICS was only used by 11.4% of children with persistent asthma. Ten percent and 18.7% of children in HK and GZ, respectively, had emergency department visits, while 16.3% and 11.6% of children in HK and GZ, respectively, had missed school secondary to asthma over the past 1 year. CONCLUSIONS: Most children in the community had intermittent asthma and addition of lung function to symptoms did not significantly affect classification of asthma severity. Significant morbidity was seen even in this group of children with mostly intermittent and mild persistent asthma.
