It is often suggested that military service members are at an increased risk for contracting Lyme disease, given that they frequently work outdoors in tick-habitats, surrounded by tall grass, brush, weeds and leaf litter. But what about their family members? Are they “safer”?
A new study examines the risk of tick-borne diseases (TBDs) in Canada in response to global warming and other environmental changes. Researchers already recognize that tick populations are spreading into new regions. Now, with temperatures rising the season for tick activity is lengthening, putting people at a greater risk.
Does an individual with a compromised immune system have a greater chance of developing disseminated Lyme disease? Studies are limited in this area. But the authors of “Erythema Migrans: Course and Outcome in Patients Treated With Rituximab” have published a limited case review, examining patients diagnosed with Lyme borreliosis (LB), who were also receiving Rituximab, a medication known to impair immunity.
In their article “Lyme Arthritis in a Military Dependent Child transferred from Japan,” Soloria and colleagues discuss the case of a 17-year-old male who relocated with his family from a U.S. military base in Japan to Virginia. 
After reading an article entitled “Assessment of Patient Nondisclosures to Clinicians of Experiencing Imminent Threats,” by Levy and colleagues, I began to wonder why some patients might not disclose they have Lyme disease to their primary care physician.
A 6-year-old child presented to her pediatrician with a circular rash on the left side of her face. The pediatrician initially assumed the rash was allergic dermatitis and prescribed topical steroids. But the rash did not improve, explains Banadyha and colleagues in their case report.
A new study by Jutras and colleagues describes a persistent antigen called peptidoglycan (PG) as a contributing factor in Lyme arthritis. “We show that B. burgdorferi has a chemically atypical PG (PGBb) that is not recycled during cell-wall turnover,” the authors write.
In their article “Malaria and Lyme disease - the largest vector-borne US epidemics in the last 100 years: success and failure of public health,” Rochlin et al.  compare various intervention strategies used to eradicate malaria with current initiatives to control the increasing incidence of tick-borne diseases.
The authors of this case series suggest that children with chronic Lyme disease symptoms be re-evaluated and diagnosed with somatic symptom disorder (SSD). Their article “Somatic symptom disorder should be suspected in children with alleged chronic Lyme disease” appears in the European Journal of Pediatrics. 
Dr. Daniel Cameron, MD, MPH, is a nationally recognized leader for his expertise in the diagnosis and treatment of Lyme disease and other tick-borne illnesses. For more than 30 years, he has been treating adolescents and adults suffering from Lyme disease.
