Abstract BACKGROUND When clinical presentation, laboratory studies, or imaging cannot diagnose cavernous sinus (CS) and/or Meckel's cave (MC) lesions, biopsy may be necessary. OBJECTIVE To review our institutional series of biopsies of indeterminate CS and MC lesions. METHODS Records from January 1994 to June 2016 were searched for biopsied indeterminate CS and MC lesions. We defined indeterminate as having an atypical imaging appearance or a broad differential and the need for tissue for definitive diagnosis. We defined primary tumors as originating from cells inherent or near the CS and MC. RESULTS Eighty-five patients were included (median age 59 [2-85] yr); 22 (28%) had a cancer history. Approaches included frontotemporal craniotomy (n = 48, 56%), endoscopic endonasal (n = 20, 24%), percutaneous transforamen ovale (n = 12, 14%), or retrosigmoid craniotomy (n = 5, 6%). Final diagnosis was metastatic in 27 (32%), primary in 21 (25%), inflammatory in 13 (15%), hematologic in 11 (13%), fungal in 5 (5%), and nondefinitive or nondiagnostic in 8 (10%) patients. Thirteen (59%) patients with a cancer history (n = 22) had a diagnosis consistent with their prior cancer; the remaining had a second pathology (n = 6, 27%) or nondiagnostic biopsy (n = 3, 14%). Two patients had surgical complications resulting in death. CONCLUSION In this patient cohort, metastatic tumors were the most likely pathology. The biopsy threshold should be lower in patients with a cancer history if clinical or radiographic diagnosis is uncertain as 27% had a second disease. However, we consider biopsy as a last resort because the risk of major morbidity/mortality, while low, is not zero.

We report single‐point and multipoint results from three statistical genetics software packages using a variance components approach for quantitative traits. When possible, we have shown the effects of covariates. Results from GENEHUNTER, SOLAR, and ACT software packages are compared for the quantitative trait immunoglobulin E (IgE) using chromosome 5 asthma familial data from Oxfordshire (England), Perth (Australia), and Freiburg (Germany), and using the genome‐wide German data. Although few differences among variance components results for GENEHUNTER, SOLAR, and ACT were detected on a limited region of chromosome 5, these packages showed larger disagreement in the German data for chromosomes 1, 9, and 14. © 2001 Wiley‐Liss, Inc.

Goals: The goal of this study is to evaluate the association between early life infections and subsequent adult onset irritable bowel syndrome (IBS). Background: Infections during adulthood are a known risk factor for adult-onset IBS. This investigation examined the role of childhood infections and infection risk factors in the development of IBS symptoms. Study: In total, 1010 subjects (509 outpatients with IBS, 501 matched controls) were mailed questionnaires regarding early-life infections during infancy (0 to 12 mo), toddler years (1 to 3 y), and child years (4 to 18 y). Comparisons between cases and controls were performed using logistic regression adjusting for age, gender, and somatization score. Results: Around 648 (64.2%) subjects responded. The median age was 51.3 years (range, 18.0 to 70.7 y) and 535 (83%) were female. Childhood (below 18 y) infections were common in cases and controls (98% vs. 98%; P=0.465), with no differences between cases and controls during infant, toddler, and child-age periods. For gastrointestinal infections experienced below 18 years, no differences were observed by infection type (bacterial, viral, or parasitic) or age group. Cases were more likely to report bronchitis by age 18 [43% vs. 25%; P=0.003; odds ratio, 1.73 (1.20-2.51)], but not other common infections. Regular antibiotic exposure was greater amongst cases (43%) than controls (30%) [P=0.09; odds ratio, 1.37 (0.96-1.96)]. The association between bronchitis and IBS case status remained significant after adjusting for antibiotic use (P=0.01). Conclusions: Greater early childhood gastrointestinal infections rates were not observed in adult individuals with IBS compared with adult controls. The study does not support a statistically significant link between early life infections and IBS aside from bronchitis.

LBA2 Background: We previously reported significant benefits in quality of life, patient satisfaction, and emergency room utilization outcomes from a large single-center randomized controlled trial comparing web-based symptom monitoring with patient-reported outcomes (PROs) vs. usual care in patients receiving chemotherapy for metastatic solid tumors (Clinicaltrials.gov: NCT00578006). We now present overall survival results from this trial. Methods: Patients receiving routine outpatient chemotherapy for metastatic solid tumors at Memorial Sloan Kettering Cancer Center were randomly assigned to self-report 12 common symptoms via tablet computers (“PRO intervention”), or to usual care. Treating physicians received symptom printouts at visits and nurses received email alerts when participants reported severe or worsening symptoms. Overall survival was tabulated based on medical records and Social Security Death Index data, estimated using the Kaplan-Meier method, and compared between arms using a log-rank test and Cox proportional hazards regression adjusting for age, sex, race, education level, and cancer type. Results: Between September 2007 and January 2011, 766 patients were randomized, with median age 61 (range 26-91), 86% white, 58% female, and 22% with less than high school education. Cancer types included genitourinary (32% of patients), gynecologic (23%), breast (19%), and lung cancer (26%). Survival results were assessed in June 2016 after a median follow up of 7 years and 517/766 (67%) of participants had died. Median overall survival in the PRO intervention arm was 5 months longer than the control arm (31.2 vs. 26.0 months, p = 0.03). In the multivariable model, results remained statistically significant with a hazard ratio of 0.832 (p = 0.04; 95% CI; 0.696, 0.995). Conclusions: Systematic symptom monitoring during outpatient chemotherapy using web-based patient-reported outcomes confers overall survival benefits. These single-center results are being further evaluated in a national multicenter implementation trial. Clinical trial information: NCT00578006.

Aims: The US National Cancer Institute recently developed the PRO-CTCAE (Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events). PRO-CTCAE is a library of questions for clinical trial participants to self-report symptomatic adverse events (e.g. nausea). The objective of this study is to inform evidence-based selection of a recall period when PRO-CTCAE is included in a trial. We evaluated differences between 1-, 2-, 3-, and 4-week recall periods, using daily reporting as the reference. Methods: English-speaking patients with cancer receiving chemotherapy and/or radiotherapy were enrolled at four US cancer centers and affiliated community clinics. Participants completed 27 PRO-CTCAE items electronically daily for 28 days, and then weekly over 4 weeks, using 1-, 2-, 3-, and 4-week recall periods. For each recall period, mean differences, effect sizes, and intraclass correlation coefficients were calculated to evaluate agreement between the maximum of daily ratings and the corresponding ratings obtained using longer recall periods (e.g. maximum of daily scores over 7 days vs 1-week recall). Analyses were repeated using the average of daily scores within each recall period rather than the maximum of daily scores. Results: A total of 127 subjects completed questionnaires (57% male; median age: 57). The median of the 27 mean differences in scores on the PRO-CTCAE 5-point response scale comparing the maximum daily versus the longer recall period (and corresponding effect size) was −0.20 (−0.20) for 1-week recall, −0.36 (−0.31) for 2-week recall, −0.45 (−0.39) for 3-week recall, and −0.47 (−0.40) for 4-week recall. The median intraclass correlation across 27 items between the maximum of daily ratings and the corresponding longer recall ratings for 1-week recall was 0.70 (range: 0.54–0.82), for 2-week recall was 0.74 (range: 0.58–0.83), for 3-week recall was 0.72 (range: 0.61–0.84), and for 4-week recall was 0.72 (range: 0.64–0.86). Similar results were observed for all analyses using the average of daily scores rather than the maximum of daily scores. Conclusion: A 1-week recall corresponds best to daily reporting. Although intraclass correlations remain stable over time, there are small but progressively larger differences between daily and longer recall periods at 2, 3, and 4 weeks, respectively. The preferred recall period for the PRO-CTCAE is the past 7 days, although investigators may opt for recall periods of 2, 3, or 4 weeks with an understanding that there may be some information loss.

AbstractBackground and AimPrimary sclerosing cholangitis (PSC) typically develops in middle‐age adults. Little is known about phenotypic differences when PSC is diagnosed at various ages. Therefore, we sought to compare the clinical characteristics of a large PSC cohort based on the age when PSC was diagnosed.MethodsWe performed a multicenter retrospective review to compare the features of PSC among those diagnosed between 1–19 (n = 95), 20–59 (n = 662), and 60–79 years (n = 102).ResultsThose with an early diagnosis (ED) of PSC were more likely to have small‐duct PSC (13%) than those with a middle‐age diagnosis (MD) (5%) and late diagnosis (LD) groups (2%), P < 0.01, and appeared to have a decrease risk of hepatobiliary malignancies: ED versus MD: hazard ratio (HR), 0.25; 95% confidence interval (CI) 0.06–1.03, and ED versus LD: HR, 0.07; 95% CI 0.01–0.62. Cholangiocarcinoma was diagnosed in 78 subjects (ED n = 0, MD n = 66, and LD n = 12) and was more likely to be diagnosed within a year after the PSC diagnosis among those found to have PSC late in life: ED 0% (0/95), MD 2% (14/662), and LD 6% (6/102), P = 0.02. Similarly, hepatic decompensation was more common among those with LD‐PSC versus younger individuals: LD versus MD: HR, 1.64; 95% CI 0.98–2.70, and LD versus ED: HR, 2.26; 95% CI 1.02–5.05.ConclusionsThose diagnosed with PSC early in life are more likely to have small‐duct PSC and less likely to have disease‐related complications. Clinicians should be vigilant for underlying cholangiocarcinoma among those with PSC diagnosed late in life.

Abstract OBJECTIVE Pulmonary complications challenge the medical management of patients who have sustained aneurysmal subarachnoid hemorrhage (SAH). We assessed the frequency and types of pulmonary complications after aneurysmal SAH and analyzed the impact of pulmonary complications on patient outcome. METHODS We reviewed the records of all patients with acute SAH treated at our institution between 1990 and 1997. Three hundred five consecutive patients with an aneurysmal hemorrhage source documented by angiography and treated within 7 days of ictus were analyzed. Outcomes at longest follow-up (mean, 16 mo) were measured by use of the Glasgow Outcome Scale. RESULTS Pulmonary complications were documented in 66 patients (22%). The pulmonary complications were nosocomial pneumonia in 26 patients (9%), congestive heart failure in 23 (8%), aspiration pneumonia in 17 (6%), neurogenic pulmonary edema in 5 (2%), pulmonary embolus in 2 (&lt;1%), and other pulmonary disorders in 4 (1%); 11 patients had two pulmonary complications. The incidence of symptomatic vasospasm was greater in patients with pulmonary complications (63%) than in patients without pulmonary complications (31%) (P= 0.001), and this association was independent of age and clinical grade at admission (odds ratio, 3.68; P&lt; 0.001). Overall clinical outcomes were worse in patients with pulmonary complications (mean Glasgow Outcome Scale score, 3.3) than in patients without pulmonary complications (mean Glasgow Outcome Scale score, 4.0; P= 0.0001), but pulmonary complications were not an independent predictor of worse outcome when adjusted for age and clinical grade at admission (odds ratio, 1.38; P= 0.315). CONCLUSION Patients who experience pulmonary complications after aneurysmal SAH have a higher incidence of symptomatic vasospasm than do patients without pulmonary complications. This most likely reflects both the failure to maintain aggressive hypervolemic and hyperdynamic therapy in patients with pulmonary compromise and the possible precipitation of congestive heart failure by hypervolemic therapy in patients with preexisting delayed ischemic neurological deficit. Although patients with pulmonary complications have worse overall clinical outcomes than do patients without pulmonary complications, this is attributable to older age and worse clinical grades at admission.

OBJECTIVENelson-Salassa syndrome (NSS) is a rare consequence of bilateral adrenalectomy (ADX) for refractory hypercortisolism due to Cushing disease (CD). Although classically defined by rapid growth of a large, invasive, adrenocorticotropin hormone (ACTH)–secreting pituitary tumor after bilateral ADX that causes cutaneous hyperpigmentation, visual disturbance, and high levels of ACTH, clinical experience suggests more variability.METHODSThe authors conducted a retrospective chart review of all patients 18 years and older with a history of bilateral ADX for CD, adequate pituitary MRI, and at least 2 years of clinical follow-up. Statistical tests included Student's t-test, chi-square test, Fisher's exact test, multivariate analysis, and derived receiver operating characteristic curves.RESULTSBetween 1956 and 2015, 302 patients underwent bilateral ADX for the treatment of hypercortisolism caused by CD; 88 had requisite imaging and follow-up (mean 16 years). Forty-seven patients (53%) had radiographic progression of pituitary disease and were diagnosed with NSS. Compared with patients who did not experience progression, those who developed NSS were significantly younger at the time of CD diagnosis (33 vs 44 years, p = 0.007) and at the time of bilateral ADX (35 vs 49 years, p = 0.007), had larger tumors at the time of CD diagnosis (6 mm vs 1 mm, p = 0.03), and were more likely to have undergone external-beam radiation therapy (EBRT, 43% vs 12%, p = 0.005). Among NSS patients, the mean tumor growth was 7 mm/yr (SE 6 mm/yr); the median tumor growth was 3 mm/yr. Prevalence of pathognomonic symptoms was low; the classic triad occurred in 9%, while hyperpigmentation without visual field deficit was observed in 23%, and 68% remained asymptomatic despite radiographic disease progression. NSS required treatment in 14 patients (30%).CONCLUSIONSNSS is a prevalent sequela of CD after bilateral ADX and affects more than 50% of patients. However, although radiological evidence of NSS is common, it is most often clinically indolent, with only a small minority of patients developing the more aggressive disease phenotype characterized by clinically meaningful symptoms and indications for treatment. Young age at the time of CD diagnosis or treatment with bilateral ADX, large tumor size at CD diagnosis, and EBRT are associated with progression to NSS and may be markers of aggressiveness.
