Arthroscopic shoulder surgery has become a safe tool for evaluation and treatment of a wide range of shoulder problems with few complications. With ever-improving technology (and commitment to motor skill development among arthroscopists), we can expect to maintain this low rate despite increasing procedure complexity. Avoiding complications in arthroscopic shoulder surgery requires careful preoperative planning, judicious patient selection, a thorough understanding of arthroscopic anatomy, and facility with arthroscopic techniques. 相似文献

Over the last few decades the there has been a huge increase in the incidence of oesophageal adenocarcinoma, surpassing that of any other solid tumour. Barrett's oesophagus is recognised as a pre-malignant cursor. Surveillance programmes have evolved to monitor Barrett's oesophagus, with the intention to detect early malignant transformation. Using photosensitive agents photodiagnosis is developing to detect this transformation before it is visible endoscopically to allow early treatment. Photodynamic therapy is a non-thermal endoscopic ablative technique, which incorporates the same photosensitive agents to treat Barrett's oesophagus as well as malignant disease. In this article we review the present status of photodiagnosis and photodynamic therapy in the management of Barrett's oesophagus and early oesophageal carcinoma. 相似文献

This study analyzed the feasibility of fitting keratoconus-affected corneas with nonkeratoconus rigid gas-permeable (RGP)
contact lenses. We retrospectively studied patients with a diagnosis of keratoconus in the past 10 years who were fitted successfully
with nonkeratoconus RGP lenses by the same physician. Results confirmed nonkeratoconus RGP lenses as the first-line correction
tool. Additionally, we found a simple equation to speed the choice of the base curves of the lenses.

Urinary tract infections (UTI) are one of the most common and serious infections among pediatric patients in the emergency department. Detection of UTI requires a systematic approach to urine testing and an understanding of the limitations to common screening tests. Proper culturing techniques are essential to the diagnosis. Accurate diagnosis and prompt treatment can reduce morbidity associated with UTIs. 相似文献
