Coronary disease morphology and distribution determined by quantitative angiography and intravascular ultrasound--re-evaluation in a cooperative multicenter intravascular ultrasound study (COMIUS).

Although previous studies have demonstrated that even quantitative coronary angiography (QCA) can not provide accurate disease morphology, there has not been a systematic comparison of disease morphology determined by QCA and intravascular ultrasound (IVUS), particularly in Japanese patients. Therefore, the present study prospectively examined patients in a multicenter cooperative study. A total of 491 coronary sites from 562 patients (446 men, 116 women; mean age, 64+/-11 years) who underwent coronary interventions were enrolled. The target lesions (>50% diameter stenosis) were evaluated pre-operatively by both QCA and IVUS operating at 30-40 MHz and the percent area stenosis, eccentricity index (EI) and lesion length were determined. The minimal (min) and maximal (max) distances from the center of the stenotic lesion to the outline of the vessel wall were measured, and the EI was calculated by the formula: [(max - min)/max]. By QCA, lesion length was determined by measuring the distance between the proximal and distal shoulders of the lesion. When the lesions were observed by IVUS with a motorized pull-back system, the length was calculated by multiplying the time for observation of the disease and 0.5 or 1 mm/s. Although the severity of the stenosis determined by QCA (86+/-10%, mean +/- SD) did not differ from that by IVUS (83+/-13%), there was no correlation between them (r=0.32, y=0.25x+65) and the correlation did not improve when lesions with remodeling, enlargement (n=176) or shrinkage (n=79) were omitted from the calculation. The EIs by QCA and IVUS were 0.51+/-0.26 and 0.52+/-0.22, respectively (NS), and there was no correlation between them (r=0.30, y=0.36x+33). However, when the lesions with remodeling were excluded, the correlation greatly improved (r=0.80, y=0.84x+10.6, p<0.05). Lesion length determined by QCA (12.4+/-6.1 mm) was significantly shorter than that by IVUS (16.3+/-8.9 mm, p<0.01). These results demonstrate that coronary angiography significantly misinterprets disease morphology in terms of severity, eccentricity and length, in part because of vessel remodeling that can be accurately determined only by IVUS.     

Ulcerative Colitis and Immunoglobulin G4

Background/Aims

Ulcerative colitis (UC) is sometimes associated with autoimmune pancreatitis (AIP). Infiltration of immunoglobulin G4 (IgG4)-positive plasma cells is sometimes detected in the colonic mucosa of AIP or UC patients. This study aimed to clarify the relation between UC and IgG4.

Methods

Associations with UC were reviewed in 85 AIP patients. IgG4 immunostaining was performed on biopsy specimens from the colonic mucosa of 14 AIP and 32 UC patients.

Results

UC was confirmed in two cases (type 1 AIP, n=1; suspected type 2 AIP, n=1). Abundant infiltration of IgG4-positive plasma cells in the colonic mucosa was detected in the case of suspected type 2 AIP with UC and two cases of type 1 AIP without colitis. Abundant infiltration of IgG4-positive plasma cells was detected in 10 UC cases (IgG4-present, 31%). Although 72% of IgG4-absent UC patients showed mild disease activity, 70% of IgG4-present patients showed moderate to severe disease activity (p<0.05).

Conclusions

UC is sometimes associated with AIP, but it seems that UC is not a manifestation of IgG4-related disease. Infiltration of IgG4-positive plasma cells is sometimes detectable in the colonic mucosa of UC patients and is associated with disease activity.     

Retrospective analysis of concurrent chemoradiation with the combination of bleomycin, ifosfamide and cisplatin (BIP) for uterine cervical cancer

Combination chemotherapy consisting of bleomycin, ifosfamide, and ciplatin (BIP) is recognized as one of the most effective chemotherapies for uterine cervical cancer. However, there have been no reports that evaluate concurrent use of radiation with BIP. The objective of this study was to evaluate the toxicity and response of the combination of BIP concurrent with radiation in patients with squamous cell carcinoma of the uterine cervix. Eligibility criteria included patients who underwent radical hysterectomy (Type III hysterectomy) as a primary treatment and revealed lymph node metastases or deep myometrial invasion (stage IB and IIA) and patients who were previously untreated (stage IIB-IV). All of the patients had biopsy-proven squamous cell carcinoma of the uterine cervix. The patients received three courses of BIP chemoradiation, and the response and toxicity were evaluated. From January 2000 to December 2003, 30 patients met study eligibility criteria. All but three patients completed 3 courses of planned chemotherapy. The frequency of severe (grade 3 and 4) toxicity was as follows: anemia, 46.7%; neutrocytopenia, 73.3%; thrombocytopenia, 16.7%; and nausea and vomiting, 23.3%. Among 30 patients, 22 cases were evaluated for response. Complete response was achieved in 16 (72.7%) of patients, with a response rate of 90.9%. In conclusion, BIP chemoradiation seems to be superior to previously reported chemoradiation regimens, and has a potential as an optimal combination chemotherapy concurrent with radiation.     

Physical Functioning,Mental Health,and Quality of Life in Different Congenital Heart Defects: Comparative Analysis in 3538 Patients From 15 Countries

BackgroundWe compared physical functioning, mental health, and quality of life (QoL) of patients with different subtypes of congenital heart disease (CHD) in a large international sample and investigated the role of functional class in explaining the variance in outcomes across heart defects.MethodsIn the cross-sectional Assessment of Patterns of Patient-Reported Outcome in Adults with Congenital Heart Disease-International Study (APPROACH-IS), we enrolled 4028 adult patients with CHD from 15 countries. Diagnostic groups with at least 50 patients were included in these analyses, yielding a sample of 3538 patients (median age: 32 years; 52% women). Physical functioning, mental health, and QoL were measured with the SF-12 health status survey, Hospital Anxiety and Depression Scale (HADS), linear analog scale (LAS) and Satisfaction with Life Scale, respectively. Functional class was assessed using the patient-reported New York Heart Association (NYHA) class. Multivariable general linear mixed models were applied to assess the relationship between the type of CHD and patient-reported outcomes, adjusted for patient characteristics, and with country as random effect.ResultsPatients with coarctation of the aorta and those with isolated aortic valve disease reported the best physical functioning, mental health, and QoL. Patients with cyanotic heart disease or Eisenmenger syndrome had worst outcomes. The differences were statistically significant, above and beyond other patient characteristics. However, the explained variances were small (0.6% to 4.1%) and decreased further when functional status was added to the models (0.4% to 0.9%).ConclusionsSome types of CHD predict worse patient-reported outcomes. However, it appears that it is the functional status associated with the heart defect rather than the heart defect itself that shapes the outcomes.     

Effect of conventional risk factors for excess cardiovascular death in men: NIPPON DATA80.

BACKGROUND: The present study examined how sex differences in conventional risk factors for cardiovascular disease (CVD), especially smoking, account for excess male mortality from CVD in Japan. METHODS AND RESULTS: In a 14-year follow-up study, causes of death were ascertained among 10,546 Japanese aged 30 years or older at the baseline. The proportion of the excess male risk of CVD explained by the differences in risk factors was estimated as (HR0-HR1)/(HR0-1), where HR0 is the age-adjusted hazard ratio (men vs women) and HR1 is the age and risk factor-adjusted hazard ratio. The age-adjusted male:female ratios were 1.60 (95% confidence interval (CI), 1.32-1.94) for CVD, 1.75 (95% CI, 1.33-2.30) for stroke, and 1.55 (95% CI, 0.97-2.49) for coronary heart disease. The proportion of excess male risk of CVD explained by smoking was 46% and excess risk explained by all risk factors including smoking was 36%. In men, drinking habits decreased the excess risk of CVD. Except for the association between drinking habits and CVD, the impact of the hazard ratios of conventional risk factors had no sex difference. CONCLUSIONS: Smoking contributes substantially to excess male mortality from CVD when the smoking rates vary substantially by sex.     

A case of rectal Dieulafoy's ulcer and successful endoscopic band ligation.

Dieulafoy's ulcer is a rare cause of gastrointestinal bleeding. The lesion is usually located in the stomach, although it may occur anywhere in the gastrointestinal tract. A 44-year-old man was admitted to hospital due to cerebral infarction. On the 23rd day of hospitalization, he showed massive hematochezia. He underwent an urgent colonoscopy. There was a visible protuberant vessel without significant ulceration at the fundus of the rectum, consistent with a Dieulafoy's ulcer. It was treated by endoscopic hemoclipping. However, rebleeding occurred three times despite repeated hemoclipping. Finally, endoscopic band ligation was successfully performed to achieve permanent hemostasis. Endoscopic band ligation is an effective treatment for bleeding rectal Dieulafoy's ulcer.
