The effect of <Emphasis Type="Italic">Clostridium butyricum</Emphasis> MIYAIRI on the prevention of pouchitis and alteration of the microbiota profile in patients with ulcerative colitis

Purpose

Ulcerative colitis (UC) is a chronic, relapsing, and refractory disorder of the intestine. Total proctocolectomy with ileal pouch anal anastomosis (IPAA) is the preferred and standard surgical procedure for patients’ refractory to medical therapy. Pouchitis is one of the most common long-term complications after IPAA. In the present study, the safety and efficacy of Clostridium butyricum MIYAIRI (CBM) as a probiotic were examined.

Methods

A randomized and placebo-controlled study was performed. Seventeen patients were recruited from 2007 to 2013. Nine tablets of MIYA-BM^® or placebo were orally administered once daily. The cumulative pouchitis-free survival, pouch condition (using the modified pouch disease activity index), and blood parameters were evaluated. A fecal sample analysis was also performed.

Results

Subjects were randomly allocated to receive MIYA-BM or placebo (9 and 8 subjects, respectively). One subject in the MIYA-BM group and four subjects in the placebo group developed pouchitis. No side effects occurred in either group. Characteristic intestinal flora was observed in each group.

Conclusions

Our results suggest that probiotic therapy with CBM achieved favorable results with minimal side effects and might be a useful complementary therapy for the prevention of pouchitis in patients with UC who have undergone IPAA.

Early positive biomarker in relation to myocardial necrosis and impaired fatty acid metabolism in patients presenting with acute chest pain at an emergency room.

BACKGROUND: Measurement of circulating biomarkers has enabled early diagnosis and risk assessment of acute coronary syndrome. This study sought diagnostic values of the first single-point data of biomarkers obtained soon after patient arrival by comparing with scintigraphically quantified myocardial injury in patients presenting with acute chest pain at an emergency room. METHODS AND RESULTS: Serial blood samples were taken soon after arrival in an emergency department in 74 patients with suspected acute coronary syndrome to quantify blood levels of troponin-T (TnT), heart-type fatty acid-binding protein (H-FABP), myocardial-bound creatine kinase (CK-MB), and myoglobin. Myocardial perfusion and metabolic defects were scintigraphically quantified. The first single-point data had high positive predictive values for detecting the defects (80-100%) but low negative predictive values (15-41%). CK-MB and TnT had higher specificities (73-100%) but significantly lower positive rates (22-27%) than the others (61-68%), resulting in greater sensitivities of H-FABP and myoglobin (75-80%) than those of CK-MB and TnT (29-35%). Among biomarkers, TnT peak concentrations most closely correlated with scintigraphic abnormalities. CONCLUSION: H-FABP can contribute to early detection of myocardial injury and TnT is most likely to correlate with injured myocardial mass. The differential features of biomarkers are complementary in patients with acute chest pain presenting at an emergency room.     

Association of smoking with intraocular pressure in middle-aged and older Japanese residents

Objectives

To clarify whether smoking was associated with elevated intraocular pressure (IOP) and to evaluate the interrelationship among IOP, blood viscosity, and smoking.

Methods

This cross-sectional study analyzed health examination data obtained between 2001 and 2004 from 1113 individuals (829 men and 284 women), ranging in age from 28 to 79 years, who had not undergone any ocular surgery or medical treatment for hypertension, ocular hypertension, and glaucoma.

Results

Multiple-regression analysis showed that systolic blood pressure (SBP), diastolic blood pressure (DBP), body mass index (BMI), and number of cigarettes smoked per day had a significantly positive association with IOP in men (P < 0.05). In women also, SBP, DBP, and BMI were positively related to IOP (P < 0.05). On the contrary, age had a significant negative association with IOP in both sexes (P < 0.01). Analysis of covariance and multiple logistic regression analyses showed that the adjusted mean IOP and the multivariate odds ratios for IOP increased with increasing cigarette consumption in men (P for trend = 0.01 and 0.06, respectively). Analysis of covariance found that smoking was significantly associated with both high IOP and high hematocrit in men (P for trend <0.05); however, the adjusted mean IOP values were higher in smokers than in nonsmokers, regardless of the hematocrit level.

Conclusions

The results of this study suggested that the IOP level may be substantially affected by smoking habit in middle-aged and older Japanese men.     

Preoperative assessment of hemifacial spasm by the coronal heavily T2-weighted MR cisternography

Background

Microvascular decompression (MVD) has become a well-established surgical procedure for hemifacial spasm (HFS). Before surgery, it is essential to evaluate any possible deformity of the brainstem and establish the precise location of the offending vessels. In the present study of HFS patients we examined coronal sections taken by heavily T2-weighted MR cisternography in addition to routine axial sections, and assessed the usefulness of these images through comparison with intraoperative findings.

Methods

Eighty patients with HFS underwent preoperative coronal heavily T2-weighted MR cisternography before microvascular decompression surgery. Three neurosurgeons examined the preoperative axial and coronal MR images and evaluated vessel invagination into the brainstem. The usefulness of coronal sections was assessed statistically by the Mann-Whitney U test.

Results

Invagination of the offending vessel into the brainstem was observed in 24 cases (30.0%). In 19 patients, it was predicted preoperatively that compression of the flocculus and brainstem would be required in order to approach the offending vessels. Coronal MR cisternography was significantly more useful in cases with vessel invagination into the brainstem than in cases without invagination.

Conclusions

Coronal sections obtained by MR cisternography are able to demonstrate the severity of vessel invagination into the brainstem as well as revealing the presence of the offending vessel. This information is helpful for planning a suitable approach to the root exit zone.
