Eyelid Myeloid Sarcoma: Ominous Presentation of Acute Myelogenous Leukemia

A 19 year-old African American man presented to our clinic for a second opinion about a right upper eyelid mass which had been recalcitrant to treatment for nonspecific orbital inflammation by an outside facility. Examination for systemic causes of the patients eyelid lesion led to a diagnosis of acute myelogenous leukemia (AML) FAB subtype M1. A subsequent biopsy of the eyelid tumor confirmed the diagnosis of a myeloid sarcoma. The patient succumbed to complications from his leukemia within 13 months of presentation. This case report is the first, to our knowledge, of an eyelid myeloid sarcoma as the presenting sign of AML and demonstrates the poor prognosis of this lesion.     

Dietary Bioactives: Establishing a Scientific Framework for Recommended Intakes

In the United States, dietary reference intakes describe the relations between nutrient intakes and indicators of adequacy, prevention of disease, and avoidance of excessive intakes among healthy populations for essential nutrients but not dietary bioactive components (DBCs), whose absence from the diet is presumably not deleterious to health (i.e., does not cause a deficiency syndrome). An appropriate framework is needed for establishing recommended intakes for which public health messages and food labeling for DBCs can be derived, because their putative health benefits may not be readily defined in the context of nutritional essentiality. In addition, a myriad of factors make determining their intake and status and investigating their discrete contributions to health particularly challenging. Therefore, the ASN Dietary Bioactive Components Research Interest Section felt it worthwhile to convene a special “hot topic” session at the 2014 Experimental Biology meeting to discuss this issue and serve as a call for future scientific dialogue on establishing a framework for recommended intakes of DBCs. This session summary captures the discussions and presentations that transpired during this session.     

Simulation Study of the Effect of Influenza and Influenza Vaccination on Risk of Acquiring Guillain-Barré Syndrome

It is unclear whether seasonal influenza vaccination results in a net increase or decrease in the risk for Guillain-Barré syndrome (GBS). To assess the effect of seasonal influenza vaccination on the absolute risk of acquiring GBS, we used simulation models and published estimates of age- and sex-specific risks for GBS, influenza incidence, and vaccine effectiveness. For a hypothetical 45-year-old woman and 75-year-old man, excess GBS risk for influenza vaccination versus no vaccination was −0.36/1 million vaccinations (95% credible interval −1.22 to 0.28) and −0.42/1 million vaccinations (95% credible interval, –3.68 to 2.44), respectively. These numbers represent a small absolute reduction in GBS risk with vaccination. Under typical conditions (e.g. influenza incidence rates >5% and vaccine effectiveness >60%), vaccination reduced GBS risk. These findings should strengthen confidence in the safety of influenza vaccine and allow health professionals to better put GBS risk in context when discussing influenza vaccination with patients.     

Macrolide-Resistant Mycoplasma pneumoniae,United States

Macrolide-resistant Mycoplasma pneumoniae (MRMP) is highly prevalent in Asia and is now being reported from Europe. Few data on MRMP are available in the United States. Using genotypic and phenotypic methods, we detected high-level MRMP in 13.2% of 91 M. pneumoniae­–positive specimens from 6 US locations.     

Multidisciplinary diabetes team care: the experiences of young adults with Type 1 diabetes

Background

This research examined whether young adults with Type 1 diabetes engage with the multidisciplinary consultation process and if not, then why.

Methods

We designed a web‐based self‐reported survey, available online from February to May 2011, for Australian adults 18–35 years with Type 1 diabetes. Respondents were asked about which clinicians they consulted to assist with self‐management. To expand on the results of the survey, we interviewed 33 respondents.

Results

Survey: Respondents (n = 150) consulted with the following clinicians: endocrinologist and diabetes educators: 23.3%; endocrinologist only: 18.0%; endocrinologist, diabetes educators and dieticians: 14.6%; endocrinologist, diabetes educators, dietician and general practitioners (GP): 11.3%; endocrinologist and GP: 10.6%; GP only: 4.6%; all clinicians recommended to assist with self‐management: 1.3%; 2.7% did not consult any clinician. Interview: Participants (n = 33) reported eight key disincentives to consultation with multidisciplinary clinicians. These were time constraints; provision of conflicting advice; inaccessibility of health services; variation in service standards; cost constraints; failure of clinicians to refer to other clinicians; lack of opportunity to build a therapeutic relationship; and failure of clinicians to engage in shared decision making.

Conclusion

Our results indicate that high attrition rates of young adults with Type 1 diabetes from recommended diabetes health services is linked to the failure of those services to meet the needs and preferences of their patients. The identified needs and preferences included joint consultation with multi‐disciplinary team clinicians; flexible access to advice by email or telephone consultation; and shared decision making. Patient engagement in health‐service re‐design has implications for improved health‐service delivery and enhanced treatment outcomes.
