The Rochester Epidemiology Project has laid the foundation for hundreds of research studies to try and answer questions about health care issues that affect our community. Listed below are some of the news articles discussing the results of publications from 2012 and 2013 using REP data.

Association of Asthma and Immunodeficiency
According to an international team of researchers, having selective IgA deficiency (sigAD) or common variable immunodeficiency (CVID) affects how much antibodies a person’s immune system can produce. Having either condition may result in recurrent infections. Using the Rochester Epidemiology Project’s linkage system, the team found that patients with a history of asthma had an increased chance of also having SigAD or CVID.

Description of Population-based Drug Utilization
Based on the Rochester Epidemiology Project’s linkage system, researchers found that nearly 70% of the Olmsted County population received at least one prescription in 2009. Over one-fifth of the population received prescriptions from 5 or more drug groups. Most commonly prescribed types of medication include antibiotics, anti-depressants, opiod analgesics (pain killers), lipid-lowering drugs, and vaccines. Differences in number and types of prescriptions were found based on sex and age; for example, women and the elderly receive more prescriptions in general.

Use of Procedure Saves Limbs from Amputation
Peripheral arterial disease – a common circulation condition – sometimes requires amputation of limbs. Surgeons can use other interventions such as stents and balloons. Using the Rochester Epidemiology Project, Dr. Peter Gloviczski and his team found that when these other treatments were used, overall rate of amputation decreased in the population.

Herpes Zoster and Eye Complications
A recent study by Dr. Barbara Yawn (REP community advisory group co-chair) and her colleagues found that patients who were diagnosed with herpes zoster were more likely to have serious or permanent eye complications. Reviewing linked records through the Rochester Epidemiology Project, they were able to find that 2.5% of patients with herpes had eye involvement. Some patients required corneal transplants and long-term treatment. Herpes zoster can be prevented by receiving the zoster vaccine.

No Link between Anesthesia and Dementia in Elderly
Dr. Sprung and his team used the Rochester Epidemiology Project and the Mayo Clinic Alzheimer’s Disease Patient Registry to look at 900, 45+ year-old, Olmsted County residents who had dementia between 1985 and 1994. These researchers note that while other factors may influence the development of dementia, receiving general anesthesia for surgery to not worsen or contribute to the development of dementia in elderly patients.

Risk of Oophorectomy after Hysterectomy
A recenty study presents findings around the risk of receiving an oophorectomy after undergoing a hysterectomy. The research team found that the incidence of such cases is under 10%, which is about 2% greater than for women who never received a hysterectomy.

Men with Fibromyalgia Often Go Undiagnosed
Researchers from Mayo Clinic’s Fibromyalgia and Chronic Fatigue Clinic published a new study that analyzed medical records and random surveys to find patients over age 21 that may have gone undiagnosed for fibromyalgia. The authors of the study found that there was a bigger difference in men reporting symptoms of fibromyalgia without a diagnosis than in women. Although this disease has numerous symptoms (like pain and insomnia) that often go untreated or are simply mistaken for symptoms other conditions, effective treatment is available for those who are diagnosed.

Incidence of Cutaneous Nontuberculous Mycobacterial Infection from 1980 to 2009
Cutaneous nontuberculous mycobacterial (NTM) infections may be found in patients after surgery, cosmetic procedures (getting a tattoo), or traumatic surgery and can result in ulcers and other skin conditions. Using data from the Rochester Epidemiology Project, researchers have found that the occurrence of this type of bacterial infection increased three-fold between 1980 and 2009. Based on these numbers, researchers recommend that other studies should look at assessing what is the most effective and appropriate treatment for patients with NTM infections.
