Objective To provide information about the clinical use of acupuncture at an academic medical centre in the USA. Methods A retrospective review of 904 patients (receiving 6070 treatments) who were referred for acupuncture treatment at the Mayo Clinic (Rochester, Minnesota, USA) between 1 January 2004 and 31 December 2008. Data gathered included age, sex, primary diagnosis, number of treatments per diagnosis and health insurance carrier. Results The mean (SD) age of the patients was 53.4 (16.2) years; 73.8% were female and 26.2% were male. The three most common diagnostic categories for which acupuncture was used were spinal pain (33.4%), pain (other) (25.1%) and joint pain (12.3%). About 42% of visits were not covered by health insurance carriers and hence patients had to pay themselves. For the remaining 58% of visits, health insurance carriers picked up all or part of the cost of the acupuncture treatments. Conclusion The results indicate that pain is the most common reason for use of acupuncture in an academic medical centre and that women use acupuncture more than men. This is one of the few reports of clinical use of acupuncture at academic medical centres in the USA.

Abstract Immunoglobulin free light chains (FLCs) are the precursors of amyloid fibrils in primary amyloidosis (AL). We studied the relationship between FLC levels and clinical features in 730 patients with newly diagnosed AL. The plasma cell clone was λ in 72% patients, and κ in 28% patients. κ-AL had more GI tract and liver involvement, where as renal involvement was more with λ-AL. While the overall survival (OS) was similar for κ and λ-AL, the median OS for those without an identifiable serum heavy chain was significantly shorter (12.6 vs 29.9 months; P = .02). The OS was shorter among those with a higher dFLC (involved FLC−uninvolved FLC; κ > 29.4 mg/dL or λ > 18.2 mg/dL using median for cutoff); 10.9 vs 37.1 months; P < .001. In multivariate analysis, dFLC was independent of other prognostic factors. The type of light chain impacts the spectrum of organ involvement and the FLC burden correlates with survival in AL.

External qigong as a pharmacotherapy adjunct was investigated in 50 subjects with chronic pain (pain lasting > 3 months with pain score of ≥ 3 on 0–10 numeric analog scale) who presented to a qigong healing center. Participants were randomized to receive either external qigong treatment (EQT) or equivalent attention time (EAT) in weekly 30-min sessions for four consecutive weeks. Outcomes were assessed before and after sessions. The primary outcome measure was intensity of pain by a 10-cm visual analog scale used to rate all pain severity measurements. At 8-week follow-up, participants were contacted by telephone and mailed a questionnaire. Most had experienced pain for > 5 years (66%); the rest, for > 3 to 5 years (8%), 1 to 3 years (10%), or < 1 year but > 3 months (10%). The most frequent concomitant diagnoses were multifactorial (26%), osteoarthritis (18%), and low back pain (12%). Most patients were also receiving other treatments (74%); none previously had EQT. Participants were randomly assigned to EQT ( n = 26) or EAT ( n = 24). These groups had no significant differences at baseline except for prior awareness of qigong (EQT 31% vs. EAT 63%; p = 0.025). Compared to the EAT group, EQT participants had a significant decrease in pain intensity in the 2nd ( p = 0.003), 3rd ( p < 0.001), and 4th weeks of treatment ( p = 0.003). At week 8, these differences in overall decreased pain intensity persisted but were not statistically significant.

Abstract Monoclonal gammopathy of undetermined significance (MGUS) is associated with a long-term risk of progression to multiple myeloma (MM) or related malignancy. To prevent serious myeloma-related complications, lifelong annual follow-up has been recommended, but its value is unknown. We reviewed all patients from southeastern Minnesota seen at Mayo Clinic between 1973 and 2004 with MGUS who subsequently progressed to MM. Of 116 patients, 69% had optimal follow-up of MGUS. Among these, abnormalities on serial follow-up laboratory testing led to the diagnosis of MM in 16%, whereas MM was diagnosed only after serious MM-related complications in 45%. In the remaining, workup of less serious symptoms (25%), incidental finding during workup of unrelated medical conditions (11%), and unknown (3%) were the mechanisms leading to MM diagnosis. High-risk MGUS patients (≥ 1.5 g/dL and/or non-IgG MGUS) were more likely to be optimally followed (81% vs 64%), and be diagnosed with MM secondary to serial follow-up testing (21% vs 7%). This retrospective study suggests that routine annual follow-up of MGUS may not be required in low-risk MGUS. Future studies are needed to replicate and expand our findings and to determine the optimal frequency of monitoring in higher-risk MGUS patients.

Abstract Obesity and black race have been associated with excess risk of multiple myeloma. The association of obesity with monoclonal gammopathy of undetermined significance (MGUS) is unknown. Further, it is not known whether the increased risk of multiple myeloma and MGUS in blacks is related to socioeconomic status, genetic susceptibility, or both. We screened 1000 black and 996 white women (range, 40-79 years) of similar socioeconomic status for MGUS; the aim of the study was to assess MGUS risk in relation to obesity and race. A total of 39 (3.9%) blacks and 21 (2.1%) whites had MGUS. On multivariate analysis, obesity (odds ratio [OR] = 1.8; P = .04), black race (OR = 1.8; P = .04), and increasing age (> 55 vs < 43 years; OR = 2.5; P = .03) were independently associated with an excess risk of MGUS. Our findings support the hypothesis that obesity is etiologically linked to myelomagenesis. The 2-fold excess of MGUS among blacks compared with whites of similar socioeconomic status supports a role for susceptibility genes in MGUS.

Abstract A diagnosis of composite lymphoma is typically prompted by the observation of morphologic discordance. We present a case of a spleen revealing histologic features of follicular lymphoma, without any indication of a second lymphoma. Immunohistochemical stains supported this diagnosis and showed the follicular lymphoma to be BCL2–. However, these studies revealed 2 additional unexpected findings: cyclin D1+ mantle zone cells surrounding neoplastic and reactive follicles (indicative of in situ mantle cell lymphoma) and BCL2-bright, histologically nonneoplastic follicles (indicative of in situ follicular lymphoma). ImmunoFISH and microdissection and polymerase chain reaction analysis documented the clonal nature of the cyclin D1+ mantle zones and illustrated clonal independence from the follicular lymphoma. This case illustrates an uncommon and unusual composite follicular and mantle cell lymphoma, with the follicular lymphoma accompanied by an in situ component, whereas the only manifestation of the mantle cell lymphoma was in situ.

Tumor lysis syndrome (TLS) presenting in absence of chemotherapy is a rare occurrence. One of the true oncological emergencies, it can lead to significant morbidity and mortality. TLS is a phenomena usually associated with tumor cell death after treatment. The etiology of the spontaneous TLS is not well understood, which complicates the diagnosis. TLS is well known to oncologists but physicians outside of this specialty have little or no experience with this condition. Early recognition and treatment are the keys to limiting the sequela of the condition. Spontaneous tumor lysis syndrome is rare but presents added risks to the patient because of the potential for delayed diagnosis and no benefit of pretreatment. Diagnosis may be further delayed because this may be the first symptom of underlying malignancy. Therefore, it is imperative that all clinicians are familiar with the syndrome to assure timely recognition.

Purpose To assess the impact of age on outcome and to analyze the projected years of life lost in patients with multiple myeloma. Patients and Methods Ten thousand five hundred forty-nine patients were evaluated; 6,996 patients were treated with conventional chemotherapy, and 3,553 patients were treated with high-dose therapy with autologous stem-cell transplantation. Results Mean observed and relative overall survival times in the entire cohort were 3.7 and 3.9 years, respectively. Observed survival decreased steadily from 6.4 years in patients younger than age 50 years to 2.5 years in patients ≥ age 80 years. A similar decrease was noted for relative survival. Higher age correlated significantly with higher International Staging System (ISS) stage. Relative excess risk of death differed significantly between 10-year age cohorts beginning from age 40 years (P < .001 for age 50 to 59 v age 40 to 49, P < .001 for age 60 to 69 v age 50 to 59, P < .001 for age 70 to 79 v age 60 to 69, and P = .009 for age ≥ 80 v 70 to 79). The average years of life lost per patient was 16.8 years in the entire patient cohort and decreased steadily from 36.1 years in patients younger than 40 years old to 4.6 years in patients ≥ age 80 years. Conclusion Age is associated with higher ISS stage and is an important risk factor for early mortality. Survival declined continuously by each decade from age 50 to age ≥ 80 from more than 6 to less than 3 years. The average of years of life lost in patients with myeloma is higher than in many other cancers and amounts to more than 30 years in patients younger than 40 years old but decreases to less than 5 years in patients age 80 years or older.
