Improved cardiac survival, freedom from MACE and angina-related quality of life after successful percutaneous recanalization of coronary artery chronic total occlusions.

Background: Most percutaneous recanalizations of coronary artery chronic total occlusion (CTO) are not attempted because of the skepticism on their long-term clinical benefit. We assessed the effect of percutaneous CTO recanalization procedures on long-term cardiac survival, freedom from MACE and angina-related quality of life (AQL).

Methods: All consecutive patients who underwent attempt of percutaneous native coronary artery CTO recanalization between 2003 and 2009 were included in the study.

Perceived musculoskeletal symptoms among dental students in the clinic work environment.

Musculoskeletal symptoms are a major concern among dental practitioners. Dental students perform the same clinical tasks as dentists in private practice, yet only recently has scientific evidence suggested a relationship between the tasks and musculoskeletal symptoms. This study investigates the clinical tasks that place students at physical risk and the relationship between the tasks and musculoskeletal symptoms.

Desmoplastic small round cell tumour: a review of literature and treatment options.

Introduction: Desmoplastic Small Round Cell Tumour (DSRCT) is a rare but aggressive malignancy with poor outcome.

Aims: To review the clinico-pathological features and radiological, histological and tumour markers of the disease and to evaluate the evidence for treatment options available.

Methods: We report a clinical case from our centre and have conducted a review of the literature from Medline (Pubmed) database from 1989 to 2007.

Physical and psychosocial stress exposures in US dental schools: the need for expanded ergonomics training.

Dental students train in an environment similar to dentists in private practice. The literature reveals that physical and psychosocial stressors in dental schools are associated with adverse health outcomes. While dental educators have provided resources to address psychosocial factors and ergonomics training at the didactic level, the reinforcement of biomechanics at the clinic level has been overlooked.

The development and role of the Read Codes.

Produced and maintained by Britain's National Health Service, the Read Codes are a comprehensive, controlled clinical vocabulary. Here's a look at how the codes evolved, their use in the NHS, and the continual process of aligning the system with the needs of its users.
