Primary Cytomegalovirus (CMV) infection is often not suspected as a cause of fever of unknown origin (FUO) in immune-competent adults. We present a case-series of symptomatic primary CMV infection in immunocompetent adults presenting as fever of unknown origin (FUO). All patients with CMV serology tested between November 2008 and June 2016 underwent chart review. Cases were defined as those between 18 and 65 years of age with documented fever and elevated serum anti-CMV IgM. Exclusion criteria were organ specific CMV disease, positive serum anti-EBV IgM, or presence of any immunocompromising condition. Sixteen patients (69% male, mean age 42.2 ± 11.7 years) met criteria. Mean duration of illness was 4.6 ± 3.3 weeks. Common symptoms other than fever included fatigue (94%), night sweats (81%), malaise (75%), myalgias (63%), and headache (56%). Eleven patients (68.8%) had contact with young children; six (35.3%) patients had children in daycare. Twelve (75%) patients had extensive testing and multiple visits or hospitalizations prior to consulting with an infectious disease specialist. Peripheral smear was done in twelve (75%) patients and all had atypical lymphocytes. Five patients (31.3%) had a leukocytosis. Peak serum transaminases were: AST 115.25 ± 50.5 IU/L and ALT 168.38 ± 92.0 IU/L. One patient had splenic infarcts. In addition, two cases of hydrops fetalis were attributed to primary CMV infection. In summary, primary CMV infection can present as FUO in immunocompetent adults. Contact with young children in daycare may be a risk factor. Heightened clinical suspicion will promote earlier diagnosis and avoid unnecessary testing.

Herbaspirillum spp. are Gram-negative bacteria that inhabit soil and water. Infections caused by these organisms have been reported in immunocompromised hosts. We describe severe community-acquired pneumonia and bacteremia caused by Herbaspirillum aquaticum or H. huttiense in an immunocompetent adult male.

A lack of research on pain management among seriously ill South Asians reveals a critical gap in the knowledge base regarding culturally responsive end-of-life care. This qualitative descriptive study investigated the perspectives of health care providers that have cared for seriously ill older South Asians, on the attitudes of US South Asians toward the management of pain experienced at end of life and the factors that influenced these attitudes. Thematic analysis of interviews and focus group discussions with 57 health care providers indicated that providers perceive South Asian patients and families to be generally reluctant to use medications to treat pain experienced at end of life. Detailed description of patient-related and culturally based reasons for this reluctance is provided along with implications for hospice and palliative care.

Background: Calciphylaxis is a rare but severe complication mostly affecting patients with end-stage renal disease (ESRD) and is associated with high morbidity and mortality. The natural history, concomitant factors, pathogenesis, and treatment for calciphylaxis remain equivocal. Methods: We conducted a retrospective study on patients diagnosed with calciphylaxis in a tertiary care center between January 1, 2012, and December 31, 2017. We describe demographics, co-morbidities, laboratory parameters, effectiveness of sodium thiosulfate treatment and outcomes. Results: Of the 30 patients (age 65.6 ± 12.79 years, male:female = 8:22), 23 (76.67%) had ESRD and were either on hemodialysis (15 [65.22%], median duration 22.5 months [range 0.2– 96 months]) or peritoneal dialysis (8 [34.78%], duration 29± 10 months). Predisposing home medications: 8 (28%) had calcium supplements, 10 (36%) had warfarin, 16 (57%) had vitamin D and 5 (18%) had iron supplements. The median parathyroid hormone (PTH) level was 239.8 pg/mL (range 4.7– 2922). Calciphylaxis was found on extremities in 21 (70%) and on torso in 6 (20%) patients. Sodium thiosulfate (STS) was given for treatment in 20 (67%) patients and 3 were cured in < 2.25 months. One-year survival for all patients with calciphylaxis was 26% (29% for STS group and 20% for those that did not receive STS) and following any surgical treatment regardless of STS use was 14%. Limitations: Retrospective design, absence of a control group and low power. Conclusion: Calciphylaxis was more common among females with a predilection for extremities over the torso. Elevations in PTH and inflammatory markers were common. Treatment with STS did not show a statistically significant improvement in survival. Those who were cured, were treated with STS up to three months.
