Physicians' Experiences as Patients with Statin Side Effects: A Case Series.
Physicians are among those prescribed statins and therefore, subject to potential statin adverse effects (AEs). There is little information on the impact of statin AEs on physicians affected by them. We sought to assess the character and impact of statin AEs occurring in physicians and retired physicians, and to ascertain whether/how personal experience of AEs moderated physicians' attitude toward statin use. Seven active or retired physicians from the United States communicated with the Statin Effects Study group regarding their personal experience of statin AEs. AE characteristics, experience with (their own) physicians, and impact of AE was ascertained. We inquired whether or how their experience altered their own attitude toward statins or statin AEs. Patient A: Atorvastatin 40 then 80 mg was followed by cognitive problems, neuropathy, and glucose intolerance in a Radiologist in his 50s (Naranjo criteria: probable causality). Patient B: Atorvastatin 10 mg was followed in 2 months by muscle weakness and myalgia in an Internist in his 40s (probable causality). Patient C: Atorvastatin, ezetimibe/simvastatin, rosuvastatin at varying doses was followed shortly after by irritability, myalgia, and fatigue in a Cardiac Surgeon in his 40s (probable causality). Patient D: Simvastatin 20 then 40 mg was followed in 4 years by mitochondriopathy, myopathy, neuropathy, and exercise intolerance in an Emergency Medicine physician in his 50s (definite causality). Patient E: Simvastatin 20 mg and niacin 1000 mg was followed in one month by muscle weakness and myalgia in a Physical Medicine and Rehabilitation physician in his 50s (probable causality). Patient F: Lovastatin 20 mg then simvastatin 20 mg, atorvastatin 20 mg, rosuvastatin 5 mg, niacin 20 mg and ezetimbe 10 mg was followed by muscle weakness and myalgia in an Obstetrician/Gynecologist in his 70s (definite causality). Patient G: Ezetimibe/simvastatin and atorvastatin (dose unavailable) was followed shortly after by cognitive problems in a Radiologist in her 80s (probable causality). Thus AEs affected multiple quality-of-life relevant domains, often in combination, encompassing muscle (N = 5), fatigue (N = 2), peripheral neuropathy (N = 2), cognitive (N = 2), dysglycemia (N = 1) and behavioral manifestations (N = 1). In five, the AEs affected the physician professionally. Five physicians experienced dismissive attitudes in some of their own healthcare encounters. One noted that his experience helped not only his own attention to statin AEs, but that of other physicians in his community. Several stated that their experience altered their understanding of and/or attitude toward statin AEs, and/or their view of settings in which statin use is warranted. Statin AEs can have profound impact in high functioning professionals with implications to the individual, their professional life, and those whom they serve professionally
EgoCor: an R package to fit exponential semi-variograms to model the local spatial correlation structure of health outcomes
As an alternative to using administrative areas for the evaluation of
small-area health inequalities, Sauzet et al suggested to take an ego-centred
approach and model the spatial correlation structure of health outcomes at
individual level. Existing tools for the analysis of spatial data in R may
appear too complex to non-specialists which may limit the use of the approach.
We present the R package EgoCor which offers a user-friendly interface
displaying in one function a range of graphics and tables of parameters to
facilitate the decision making about which exponential parameters fit best
either raw data or residuals. This function is based on the functions of the R
package gstat. Moreover, we implemented a function providing the measure of
uncertainty proposed by Dyck and Sauzet. With the R package EgoCor the
modelling of spatial correlation structure of health outcomes with a measure of
uncertainty is made available to non specialists.Comment: Keywords: R package, semi-variogram, exponential models, small-area

Recent research on Gulf War illness and other health problems in veterans of the 1991 Gulf War: Effects of toxicant exposures during deployment
Veterans of Operation Desert Storm/Desert Shield - the 1991 Gulf War (GW) - are a unique population who returned from theater with multiple health complaints and disorders. Studies in the U.S. and elsewhere have consistently concluded that approximately 25-32% of this population suffers from a disorder characterized by symptoms that vary somewhat among individuals and include fatigue, headaches, cognitive dysfunction, musculoskeletal pain, and respiratory, gastrointestinal and dermatologic complaints. Gulf War illness (GWI) is the term used to describe this disorder. In addition, brain cancer occurs at increased rates in subgroups of GW veterans, as do neuropsychological and brain imaging abnormalities. Chemical exposures have become the focus of etiologic GWI research because nervous system symptoms are prominent and many neurotoxicants were present in theater, including organophosphates (OPs), carbamates, and other pesticides; sarin/cyclosarin nerve agents, and pyridostigmine bromide (PB) medications used as prophylaxis against chemical warfare attacks. Psychiatric etiologies have been ruled out. This paper reviews the recent literature on the health of 1991 GW veterans, focusing particularly on the central nervous system and on effects of toxicant exposures. In addition, it emphasizes research published since 2008, following on an exhaustive review that was published in that year that summarizes the prior literature (RACGWI, 2008). We conclude that exposure to pesticides and/or to PB are causally associated with GWI and the neurological dysfunction in GW veterans. Exposure to sarin and cyclosarin and to oil well fire emissions are also associated with neurologically based health effects, though their contribution to development of the disorder known as GWI is less clear. Gene-environment interactions are likely to have contributed to development of GWI in deployed veterans. The health consequences of chemical exposures in the GW and other conflicts have been called "toxic wounds" by veterans. This type of injury requires further study and concentrated treatment research efforts that may also benefit other occupational groups with similar exposure-related illnesses
