A 23-year-old woman presented to the emergency department with severe occipital headache, nausea and fever. She was treated with intravenous antibiotics for suspected meningitis. After a brief period of response, her symptoms relapsed and remained refractory despite continuing intravenous antibiotics for 10 days leading to referral to our centre. Physical examination was significant for tender right cervical lymph node. Initial tests included pancytopenia, elevated C reactive protein, lactate dehydrogenase and unremarkable cerebrospinal fluid. Extensive infectious and rheumatology work-up was negative. Massive posterior cervical, axillary and inguinal lymphadenopathy was revealed on imaging. Excisional biopsy of the deep cervical lymph node showed histiocytic necrotising lymphadenitis suggesting a diagnosis of Kikuchi disease. Her course was complicated by acute renal failure. Her symptoms resolved in about a week with supportive treatment along with improvement in pancytopenia and renal function. She had two additional self-limited recurrences in the next 3 months and remains symptom free thereafter.

Consensus abstract Background The management of primary rectal cancer beyond total mesorectal excision planes (PRC-bTME) and recurrent rectal cancer (RRC) is challenging. There is global variation in standards and no guidelines exist. To achieve cure most patients require extended, multivisceral, exenterative surgery, beyond conventional total mesorectal excision planes. The aim of the Beyond TME Group was to achieve consensus on the definitions and principles of management, and to identify areas of research priority. Methods Delphi methodology was used to achieve consensus. The Group consisted of invited experts from surgery, radiology, oncology and pathology. The process included two international dedicated discussion conferences, formal feedback, three rounds of editing and two rounds of anonymized web-based voting. Consensus was achieved with more than 80 per cent agreement; less than 80 per cent agreement indicated low consensus. During conferences held in September 2011 and March 2012, open discussion took place on areas in which there is a low level of consensus. Results The final consensus document included 51 voted statements, making recommendations on ten key areas of PRC-bTME and RRC. Consensus agreement was achieved on the recommendations of 49 statements, with 34 achieving consensus in over 95 per cent. The lowest level of consensus obtained was 76 per cent. There was clear identification of the need for referral to a specialist multidisciplinary team for diagnosis, assessment and further management. Conclusion The consensus process has provided guidance for the management of patients with PRC-bTME or RRC, taking into account global variations in surgical techniques and technology. It has further identified areas of research priority.

Genetic College Many genomic elements in humans are associated with behavior, including educational attainment. In a genome-wide association study including more than 100,000 samples, Rietveld et al. (p. 1467 , published online 30 May; see the Perspective by Flint and Munafò ) looked for genes related to educational attainment in Caucasians. Small genetic effects at three loci appeared to impact educational attainment.

We hypothesized that demographic/anthropometric parameters can be used to estimate effective reflecting distance (EfRD), required to derive aortic pulse wave velocity (APWV), a prognostic marker of cardiovascular risk, from peripheral waveforms and that such estimates can discriminate differences in APWV and EfRD with aging and habitual endurance exercise in healthy adults. Ascending aortic pressure waveforms were derived from peripheral waveforms (brachial artery pressure, n = 25; and finger volume pulse, n = 15) via a transfer function and then used to determine the time delay between forward- and backward-traveling waves (Δ tf-b). True EfRDs were computed as directly measured carotid-femoral pulse wave velocity (CFPWV) × ½Δ tf-b and then used in regression analysis to establish an equation for EfRD based on demographic/anthropometric data (EfRD = 0.173·age + 0.661·BMI + 34.548 cm, where BMI is body mass index). We found good agreement between true and estimated APWV (Pearson's R2 = 0.43; intraclass correlation = 0.64; both P < 0.05) and EfRD ( R2 = 0.24; intraclass correlation = 0.40; both P < 0.05). In young sedentary (22 ± 2 years, n = 6), older sedentary (62 ± 1 years, n = 24), and older endurance-trained (61 ± 2 years, n = 14) subjects, EfRD (from demographic/anthropometric parameters), APWV, and ½Δ tf-b (from brachial artery pressure waveforms) were 52.0 ± 0.5, 61.8 ± 0.4, and 60.6 ± 0.5 cm; 6.4 ± 0.3, 9.6 ± 0.2, and 8.1 ± 0.2 m/s; and 82 ± 3, 65 ± 1 and 76 ± 2 ms (all P < 0.05), respectively. Our results demonstrate that APWV derived from peripheral waveforms using age and BMI to estimate EfRD correlates with CFPWV in healthy adults. This method can reliably detect the distal shift of the reflecting site with age and the increase in APWV with sedentary aging that is attenuated with habitual endurance exercise.

AbstractBackgroundFactors associated with abdominal pain in gastroparesis are incompletely evaluated and comparisons of pain vs other symptoms are limited. This study related pain to clinical factors in gastroparesis and contrasted pain/discomfort‐ with nausea/vomiting‐predominant disease.MethodsClinical and scintigraphy data were compared in 393 patients from seven centers of the NIDDK Gastroparesis Clinical Research Consortium with moderate‐severe (Patient Assessment of Upper Gastrointestinal Disorders Symptoms [PAGI‐SYM] score ≥3) vs none‐mild (PAGI‐SYM < 3) upper abdominal pain and predominant pain/discomfort vs nausea/vomiting.Key ResultsUpper abdominal pain was moderate‐severe in 261 (66%). Pain/discomfort was predominant in 81 (21%); nausea/vomiting was predominant in 172 (44%). Moderate‐severe pain was more prevalent with idiopathic gastroparesis and with lack of infectious prodrome (P ≤ 0.05) and correlated with scores for nausea/vomiting, bloating, lower abdominal pain/discomfort, bowel disturbances, and opiate and antiemetic use (P < 0.05), but not gastric emptying or diabetic neuropathy or control. Gastroparesis severity, quality of life, and depression and anxiety were worse with moderate‐severe pain (P ≤ 0.008). Factors associated with moderate‐severe pain were similar in diabetic and idiopathic gastroparesis. Compared to predominant nausea/vomiting, predominant pain/discomfort was associated with impaired quality of life, greater opiate, and less antiemetic use (P < 0.01), but similar severity and gastric retention.Conclusions & InferencesModerate‐severe abdominal pain is prevalent in gastroparesis, impairs quality of life, and is associated with idiopathic etiology, lack of infectious prodrome, and opiate use. Pain is predominant in one fifth of gastroparetics. Predominant pain has at least as great an impact on disease severity and quality of life as predominant nausea/vomiting.

The objective of this study is to characterize the outcomes of primary antifungal prophylaxis with voriconazole in patients receiving intensive chemotherapy for acute myelogenous leukemia (AML) or myelodysplastic syndromes (MDS). We conducted a single center, retrospective, cohort study of consecutive adult patients with AML or MDS at Mayo Clinic between January 1, 2006 and July 1, 2010. The study included patients undergoing induction or first relapse combination chemotherapy who received voriconazole 200 mg orally twice daily as prophylaxis during the neutropenic phase. Patient records were evaluated until 30 days after neutrophil recovery for development of invasive fungal infection (IFI) as defined per EORTC/MSG 2008 criteria with computed tomography scans independently reviewed by a radiologist. Therapeutic drug monitoring and reasons for voriconazole discontinuation were documented. Twenty four episodes of IFI were detected among 165 consecutive patients for an overall incidence of 145 per 1000 patients. The incidence of IFI was 24, 42, and 78 per 1000 patients for proven, probable, and possible infection, respectively. Four patients developed proven IFI (n = 2 Aspergillus spp., n = 2 Rhizopus spp.). Serum voriconazole trough concentrations were available in 39 patients, and no statistically significant difference in voriconazole trough level was observed between those with versus without an IFI. Voriconazole prophylaxis was discontinued in 81 patients due to suspected IFI (n = 24), fever of unknown origin (n = 19), adverse events (n = 23), and other causes (n = 17). Voriconazole as primary IFI prophylaxis is safe and may be beneficial in AML/MDS patients receiving intensive chemotherapy. Am. J. Hematol. 88:283–288, 2013. © 2013 Wiley Periodicals, Inc.
