Public knowledge and attitudes towards cardiopulmonary resuscitation in Hong Kong: telephone survey.
To investigate the public's knowledge and attitudes about cardiopulmonary resuscitation in Hong Kong. ⋯ Knowledge of cardiopulmonary resuscitation was still poor among the public in Hong Kong and the percentage of population trained to perform it was also relatively low. Efforts are needed to promote educational activities and explore other approaches to skill reinforcement and refreshment. Besides, we suggest enacting laws to protect bystanders who offer cardiopulmonary resuscitation, and incorporation of relevant training course into secondary school and college curricula.

The pathogenesis and management of lateral epicondylalgia, or tennis elbow, a common ailment affecting middle-aged subjects of both genders continue to provoke controversy. Currently it is thought to be due to local tendon pathology, pain system changes, and motor system impairment. Its diagnosis is usually clinical, based on a classical history, as well as symptoms and signs. ⋯ Different treatment modalities have been described, including the use of orthotics, non-steroidal anti-inflammatory drugs, steroid injections, topical glyceryl trinitrate, exercise therapy, manual therapy, ultrasound therapy, laser therapy, extracorporeal shockwave therapy, acupuncture, taping, platelet-rich plasma injections, hyaluronan gel injections, botulinum toxin injections, and surgery. Nevertheless, evidence to select the best treatment is lacking and the choice of therapy depends on the experience of the management team, availability of the equipment and expertise, and patient response. This article provides a snapshot of current medical practice for lateral epicondylalgia management.

Randomized Controlled Trial Comparative Study
Elective unilateral total knee replacement using continuous femoral nerve blockade versus conventional patient-controlled analgesia: perioperative patient management based on a multidisciplinary pathway.
OBJECTIVES. To evaluate the effectiveness of our new multidisciplinary pathway for total knee replacement patients and compare outcomes after continuous femoral nerve blockade versus conventional patient-controlled analgesia for postoperative pain. DESIGN. ⋯ CONCLUSION. Continuous femoral nerve blockade proved to be a feasible and better alternative mode of postoperative analgesia than our conventional patient-controlled analgesia. Our new multidisciplinary management pathway and multimodal analgesic regimen featuring the continuous femoral nerve blockade appeared beneficial to patients and effective in our clinical setting.

Comparative Study
Intensive care unit admission of obstetric cases: a single centre experience with contemporary update.
OBJECTIVES. To review the characteristics of a series of obstetric patients admitted to the intensive care unit in a regional hospital in 2006-2010, to compare them with those of a similar series reported from the same hospital in 1989-1995 and a series reported from another regional hospital in 1998-2007. DESIGN. ⋯ There was an increasing trend of intensive care unit admissions following elective caesarean section for placenta praevia and for early aggressive intervention of pre-eclampsia. Maternal mortality remained low but had not decreased. The intensive care unit admission rate by itself might not be a helpful indicator of obstetric performance.

Comparative Study
Benchtop study of leakages across the Portex, TaperGuard, and Microcuff endotracheal tubes under simulated clinical conditions.
OBJECTIVES. To compare three endotracheal tubes for leakage across the cuff (microaspiration) under a comprehensive set of simulated clinical situations. These were the Mallinckrodt TaperGuard (Covidien, US) with a tapered polyvinyl chloride cuff; the KimVent Microcuff (Kimberly-Clark Health Care, US) with a cylindrical polyurethane cuff; and a conventional Portex (Smiths Medical International Ltd, UK) with a globular polyvinyl chloride cuff. ⋯ Clinical scenarios associated with the greatest leakage were mechanical ventilation with zero positive end-expiratory pressure, circuit disconnection with spontaneous breathing efforts, application of suction, and a low cuff pressure. CONCLUSIONS. Microcuff endotracheal tubes outperformed TaperGuard and Portex endotracheal tubes in preventing microaspiration, which is one of the major mechanisms for ventilator-associated pneumonia.
