BackgroundA Memorial Sloan Kettering (MSKCC) nomogram predicts disease specific survival (DSS) for gastric adenocarcinoma. The goal of this study is to use a cancer registry to compare nomogram predicted survival with actual survival in the general population.MethodsAll patients undergoing surgery for gastric adenocarcinoma from the Surveillance, Epidemiology, and End Results (SEER) database (1988–2012) were studied.Results6954 patients were identified. Majority of cancers were in the antrum (30.2%), and had intestinal histology (73.7%). Median follow‐up was 8.2 years. Five year DSS for nomogram risk groups (0–25%, 26–50%, 51–75%, and 76–100%) was 23%, 48%, 57%, and 81% respectively. Actual DSS was 7–15% lower than nomogram predicted DSS. Relative to patients in the 76–100% 5‐year DSS risk group, patients in the 0–25%, 26–50%, and 51–75% groups had significantly higher risks of death with hazard ratios of 6.84 (95%CI 6.12–7.65), 3.30 (95%CI 2.83–3.86), and 2.64 (95%CI 2.30–3.03), respectively (all P < 0.001). The concordance index for 5‐year nomogram predicted DSS was 0.68 (95%CI 0.67–0.69).ConclusionsThe MSKCC gastric cancer nomogram over‐estimates DSS from gastric cancer in the general population and has a moderate concordance index. Predictive tools generated at specialized institutions may not perform as well in the general population. J. Surg. Oncol. 2015; 112:377–380. © 2015 Wiley Periodicals, Inc.

BACKGROUND: Poliomyelitis is a viral infectious disease caused by 1 of the 3 strains of poliovirus. The World Health Organization launched an eradication campaign in 1988. Although the number of cases of poliomyelitis has drastically declined, eradication has not yet been achieved, and there are a substantial number of survivors of the disease. Survivors of poliomyelitis present a unique set of challenges to the anesthesiologist. The scientific literature regarding the anesthetic management of survivors of poliomyelitis, however, is limited and primarily experiential in nature. Using a retrospective, matched cohort study, we sought to more precisely characterize the anesthetic implications of poliomyelitis and to determine what risks, if any, may be present for patients with a history of the disease. METHODS: Using the Mayo Clinic Life Sciences System Data Discovery and Query Builder, study subjects were identified as those with a history of paralytic poliomyelitis who had undergone major surgery at Mayo Clinic Rochester between 2005 and 2009. For each case, 2 sex- and age-matched controls that underwent the same surgical procedure during the study period were randomly selected from a pool of possible controls. Medical records were manually interrogated with respect to demographic variables, comorbid conditions, operative and anesthetic course, and postoperative course. RESULTS: We analyzed 100 cases with 2:1 matched controls and found that the peri- and postoperative courses were very similar for both groups of patients. Pain scores, postanesthesia care unit admission, length of postanesthesia care unit stay, intensive care unit admission, length of intensive care unit stay, and initial extubation location were not significantly different between the 2 groups. Looking at pulmonary complications in our primary outcome, there was no significant difference between the 2 groups (17% vs 14% for polio versus control, respectively; conditional logistic regression odds ratio = 1.5; 95% confidence interval, 0.7–3.3; P = 0.33). In addition, no difference was noted in those requiring a code or rapid response team intervention (4% vs 3% for polio versus control; P = 0.46) and the 30-day mortality rate was also not significantly different, with 2% of polio patients dying compared with 3% of controls ( P = 0.79). The analysis of the primary outcome was repeated for the subset of patients with a history of poliomyelitis who had persistent neurologic deficits preoperatively ( n = 36) and their matched controls ( n = 72). In this subset analysis, there were 4 (11%) polio patients and 8 (11%) control patients who experienced pulmonary complications (conditional logistic regression odds ratio = 1.00; 95% confidence interval, 0.27–3.72; P = 1.00). The percentage of patients experiencing specific pulmonary complications of interest was similar between groups (postoperative mechanical ventilation: 6% vs 8% for polio and control patients, respectively; prolonged mechanical ventilation: 0% vs 1%; reintubation: 8% vs 4%; pulmonary infection: 6% vs 6%; and aspiration: 0% vs 1%). CONCLUSIONS: This study suggests that patients with a history of poliomyelitis do not seem to have an increased risk of pulmonary complications in the perioperative period. However, an odds ratio as great as 3.3-fold may be present.

Alternative splices capable of generating proteins with altered functions were found (by PCR) in isoform 2 of the rat plasma membrane Ca2+ pump. These splices were concentrated in two hypervariable regions. One of these regions, near the N-terminus and the lipid-binding region, could be altered by the insertion of either or both of inserts x and y. Insertion of both x and y would add 45 amino acids to the molecule. The y insert causes the appearance of a rather hydrophobic stretch of amino acids in the middle of a highly polar region. The second variable region begins in the middle of the calmodulin-binding domain. Insertion of 229 nucleotides at this point of the message converts the b form to the a form, which has an altered (and shorter) C-terminus. The calmodulin-binding domain of this shortened form has a less basic character, which would decrease the affinity for calmodulin. The b form of isoenzyme 2 contains relatively weak protein kinase A substrate sequences, such as KQNSS and KNNS. These sequences are eliminated in form a, and a strongly activated kinase substrate sequence, RRQSS, appears in a different place. Different tissues use different combinations of alternative splices, with heart and brain showing the greatest diversity.

Abstract A case is presented of sudden death during physical activity in a 15-year-old boy with clinically inactive mucocutaneous lymph node syndrome (Kawasaki disease). At autopsy, the coronary arteries were involved by multiple aneurysms and obstructive thrombi, and the left ventricular myocardium was extensively scarred. Although Kawasaki disease most commonly occurs in infants and young children, it may be a cause of sudden death in adolescents.

Abstract Psychiatric and psychological assessment of criminal defendants is often complicated by the retrospective nature requiring (1) an overreliance on self-reported data and (2) the need to achieve a high degree of certainty in formulating the diagnosis and subsequent expert opinion within the context of an adversarial evaluation. The Multiple Schedule of Affective Disorders and Schizophrenia (SADS) evaluation involves the application of an extensive diagnostic interview that has demonstrated a high degree of reliability and satisfactory validity in making current and lifetime diagnoses. The multiple SADS entails sequential administrations of the SADS, first to the defendant and later to significant others regarding the defendant's functioning during the time period in question. This comprehensive approach allows for the systematic examination of individual symptoms and the clear delineation of disparities and areas of agreement. Usefulness of the multiple SADS evaluation is exemplified in a case study involving criminal responsibility.

Abstract Background. The salivary gland is one of the most common sites involved by nongastric, extranodal marginal zone lymphomas of mucosa-associated lymphoid tissue (MALT). A large series of patients with long-term follow-up has not been documented. This multicenter, international study sought to characterize the clinical characteristics, treatment, and natural history of salivary gland MALT lymphoma. Methods. Patients with biopsy-confirmed salivary gland MALT lymphoma were identified from multiple international sites. Risk factors, treatment, and long-term outcomes were evaluated. Results. A total of 247 patients were evaluated; 76% presented with limited-stage disease. There was a history of autoimmune disorder in 41%, with Sjögren disease being the most common (83%). Fifty-seven percent of patients were initially treated with local therapy with surgery, radiation, or both; 37 of patients were treated with systemic therapy initially, with 47% of those receiving rituximab; and 6% of patients were observed. The median overall survival (OS) was 18.3 years. The median progression-free survival (PFS) following primary therapy was 9.3 years. There was no difference in the outcomes between patients receiving local or systemic therapy in first-line management. On multivariate analysis, age &lt;60 years and low to intermediate international prognostic index were associated with improved OS and PFS; Sjögren disease was associated with improved OS. Conclusion. Salivary gland MALT lymphoma has an excellent prognosis regardless of initial treatment, and patients with Sjögren disease have improved survival. Risks for long-term complications must be weighed when determining initial therapy. Implications for Practice: Patients with salivary gland extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT) have an excellent prognosis, particularly those with associated Sjögren's disease. A wide range of available therapies may provide similar durable rates of disease control and survival. Therefore, an important goal in selection of therapy should be to minimize morbidity from treatment. When determining initial therapy for these patients, practitioners should consider the potential side effects and long-term toxicities of treatment.
