In order to consider the ethical issues around vaccine distribution during an influenza pandemic, it is critical to have an understanding of the role of influenza vaccine in a pandemic, the rate at which vaccine is likely to be come available, who will likely produce and "own" the vaccine, how vaccine distribution and administration might be accomplished, and which are the groups that might be deemed highest priority to be vaccinated against influenza. The United States and Connecticut have been considering the more challenging of these issues and have learned from Canada, which previously discussed and made decisions on the challenges related to vaccine distribution. Although there is still some critical advance thinking that needs to be done, planning for the response to an influenza pandemic is now at an advanced stage. The keys to preparedness at this stage are to be aware of the vaccine distribution options, to know the benefits and limitations of each option, and to be flexible but nimble in dealing with a real pandemic.

The specialty of colon and rectal surgery: its impact on patient care and role in academic medicine.
The specialty of colon and rectal surgery, a specialty of general surgery, has evolved from the field of proctology. Clinical care has demonstrated decreased number of patients requiring intestinal stomas, improved quality of life in patients with benign anorectal disorders, and more favorable results in patients afflicted with primary and recurrent colorectal cancer. Basic science investigations have spawned from clinical questions such as the molecular biology of colorectal cancer, use of cyclooxygenase inhibitors and polyp regression, and novel cytokine antagonists in inflammatory bowel disease. ⋯ Surgical residents benefit by having a colorectal surgeon on the faculty by repetitive exposure to anorectal surgery, low pelvic anastomoses, stoma creation and closure, and surgery involving the small intestine. Senior colorectal surgeons will develop critical pathways for the healthcare delivery of patients afflicted with colorectal disease. The specialty of colorectal surgery will continue to translate into improved patient care and positively impact in academic medicine by providing expertise into student and resident training and generate highly sophisticated clinical and basic science investigations.

The physical examination has a historically prominent role in medical practice, being an important tool in diagnosis and in developing rapport with patients. Yet, physicians have lost bedside skills in recent years, with increasing use of technology at the expense of time spent with the patient. ⋯ Approaches to improve bedside diagnosis skills include increased emphasis on instruction in physical examination during medical school and postgraduate training, and careful scrutiny of physical examination techniques, with formal evaluation of their accuracy and reproducibility. Only through education and research will the physical examination recover its central role in the clinical encounter.

The increased number of vaginal yeast infections in the past few years has been a disturbing trend, and the scientific community has been searching for its etiology. Several theories have been put forth to explain the apparent increase. First, the recent widespread availability of low-dosage, azole-based over-the-counter antifungal medications for vaginal yeast infections encourages women to self-diagnose and treat, and women may be misdiagnosing themselves. ⋯ Second, medical technology has increased the life span of seriously immune compromised individuals, yet these individuals are frequently plagued by opportunistic fungal infections. Long-term and intense azole-based antifungal treatment has been linked to an increase in resistant Candida and non-Candida species. Thus, the future of limiting antifungal resistance lies in identifying the factors promoting resistance and implementing policies to prevent it.

Sepsis, manifested by systemic inflammatory response syndrome (SIRS), septic shock and multiple organ dysfunction syndrome (MODS), remains the leading cause of morbidity and mortality in critically ill patients. Despite advances and our knowledge of sepsis, there remain clinical dilemmas that impact how we treat patients. ⋯ As we improve our understanding of sepsis, there is increased recognition that improvement in morbidity and survival will come not only from treating the manifestations of sepsis but also the endogenous mediators responsible for the development of these clinically important conditions. This manuscript discusses the clinical dilemmas associated with sepsis, current therapy and future directions for managing sepsis.
