Preoperative Serum Carcinoembryonic Antigen Level as a Predictive Factor of Recurrence After Curative Resection of Colorectal Cancer

Background  We evaluated the prognostic value of the preoperative serum carcinoembryonic antigen (CEA) level in patients with colorectal cancer (CRC). Patients and Methods  The study group comprised 638 patients. The optimal cutoff value for the preoperative serum CEA level was determined. Predictive factors of recurrence were evaluated using multivariate analyses. The relapse-free time was investigated according to the CEA level. Results  All patients underwent potentially curative resection for CRC without distant metastasis, classified as stage I, II, or III. The optimal cutoff value for preoperative serum CEA level was 10 ng/ml. Elevated preoperative serum CEA level was observed in 92 patients. Multivariate analysis identified tumor–node–metastasis (TNM) stage and preoperative serum CEA level as independent predictive factors of recurrence. The relapse-free survival between CEA levels >10 ng/ml and <10 ng/ml significantly differed in patients with stage II and III. However, there was no significant difference in relapse-free survival between CEA levels >10 ng/ml and <10 ng/ml in patients with stage I. Conclusion  Preoperative serum CEA is a reliable predictive factor of recurrence after curative surgery in CRC patients and a useful indicator of the optimal treatment after resection, particularly for cases classified as stage II or stage III.     

Spirotoamides A and B, novel 6,6-spiroacetal polyketides isolated from a microbial metabolite fraction library

Two new 6,6-spiroacetal polyketides, spirotoamides A (1) and B (2), were isolated from a microbial metabolite fraction library of Streptomyces griseochromogenes JC82-1223 by screening of structurally unique compounds based on a search of spectral database. The fraction library was constructed using a systematic separation method to efficiently discover new metabolites from microbial sources such as actinomycetes and fungi. The structures of 1 and 2 were elucidated by 2D-NMR and mass spectrometric measurements. They belong to a class of polyketides, and contain a 6,6-spiroacetal core structure and a carboxamide group. The biosynthetic pathway of 1 and 2 is discussed in the text.     

Abnormal Axon Reflex-Mediated Sweating Correlates with High State of Anxiety in Atopic Dermatitis

BackgroundSweating plays a key role in skin homeostasis, including antimicrobial and moisturizing effects, and regulation of skin surface pH. Impaired axon reflex-mediated (AXR) sweating has been observed in patients with atopic dermatitis (AD). However, the mechanism of such abnormal sudomotor axon reflex remains to be revealed.MethodsTo investigate this mechanism, sudomotor function was analyzed using a quantitative sudomotor axon reflex test (acetylcholine iontophoresis) in patients with AD (n = 26) and healthy volunteers (n = 12). Correlation between sudomotor function and certain background factors, including Spielberger State Trait Anxiety Inventory score, Severity Scoring of Atopic Dermatitis (SCORAD) score, number of circulating eosinophils, and serum concentrations of thymus and activation-regulated chemokine and immunoglobulin E radioimmunosorbent test, was validated.ResultsLatency time was significantly prolonged in AD (p = 0.0352), and AXR sweating volume (mg/0-5 min) was significantly lower in AD patients than in healthy controls (p = 0.0441). Direct sweating volume (mg/0-5 min) was comparable in AD patients and healthy controls. A significant correlation between the evaluation results of quantitative sudomotor axon reflex tests and certain background factors was not observed. The latency time in non-lesioned and lesioned areas for AD patients versus continuous anxiety value in the Spielberger State Trait Anxiety Inventory and the AXR versus SCORAD showed significant correlations (p = 0.0424, p = 0.0169, and p = 0.0523, respectively).ConclusionsAlthough the number of study subjects was little, abnormal AXR sweating in patients with AD was observed. Correlative analysis suggests possible involvement of continuous anxiety and the immune system in such abnormal sudomotor function.     

An Analytical Model / Emotional Intelligence Quotient and QOL in Mothers with Infants in Japan

Objective: The purpose of this study was to examine the relationship betweenthe emotional intelligence quotient and health-related quality of life using structuralequation modeling.Methods: A self-administered questionnaire survey was conducted among 1,911mothers who visited the Health Center for an infant medical examination. A hypotheticalmodel was constructed using variables of the emotional intelligence quotient, socialsupport, coping, parenting stress, and perceived health competence.Result: There were a total of 1,104 valid responses (57.8%). Significantstandardized estimates were obtained, confirming the goodness of fit issues with themodel. The emotional intelligence quotient had a strong impact on physical andpsychological quality of life, and showed the greatest association with coping. This studydiffered from previous studies in that, due to the inclusion of social support andexplanatory variables in coping, an increase in coping strategies was more highlyassociated with emotional intelligence quotient levels than with social support.Conclusion: An enhanced emotional intelligence quotient should be considereda primary objective to promote the health of mothers with infant children.     

RE‐EPITHELIALIZATION OF SQUAMOUS EPITHELIUM FOR A RADIATION‐INDUCED RECTAL ULCER WHILE GIVING AN ECABET SODIUM ENEMA

The present patient developed a severe rectal ulcer more than 1 month after having received external beam radiation therapy for prostate cancer. Surveillance endoscopy every 3 months demonstrated healing of this rectal ulcer using a novel therapy. He was given enemas with ecabet sodium, which provides physical protection and promotes healing by increasing prostaglandin E₂, and this process induced squamous metaplasia that halted the progression of the ulcer of radiation proctitis as a late‐phase reaction. Intrapapillary capillary loops were visualized with magnified narrow band imaging at the healing ulcer site as seen via the esophagus and, moreover, demonstrated histologically.     

Comparison of endoscopic findings with symptom assessment systems (FSSG and QUEST) for gastroesophageal reflux disease in Japanese centres

Background and Aim: We compared endoscopic findings of the frequency scale for the symptoms of gastroesophageal reflux disease (FSSG), a written questionnaire developed in Japan, to that for the questionnaire for the diagnosis of reflux esophagitis (QUEST) for the diagnosis of reflux esophagitis. Methods: We registered 475 patients with untreated symptoms of upper abdominal pain (male/female: 252/223, average age 52.4 ± 17.8 years). Subjects were assessed first with the FSSG and QUEST questionnaires, then by endoscopy, before allocation to a gastric ulcer (GU), duodenal ulcer (DU), gastroesophageal reflux disease (GERD) or functional dyspepsia (FD) group. Results: On the basis of the endoscopic findings the diagnoses for the 475 subjects were as follows: FD 52.2%, DU 7.6%, GU 7.8%, and GERD 32.4% (Grade M 10.1%, Grade A + B 20.2%, Grade C + D 2.3%). There was no difference between the FSSG and QUEST in sensitivity, specificity or accuracy for any condition. The FSSG score rose with increasing endoscopic severity of GERD, but there was no correlation between the QUEST score and endoscopic severity. The FSSG total score was inferior to QUEST in terms of distinguishing GERD from other conditions, but when only the questions relating to reflux symptoms were used, the FSSG was able to distinguish GERD from other conditions as well as QUEST. Conclusions: The FSSG score reflects the severity of the endoscopic findings of GERD.
