Using health-related quality of life measures to predict cardiac function in survivors exposed to anthracyclines.

PURPOSE: As the number of pediatric cancer survivors increases, so does the number of survivors previously exposed to anthracyclines as part of their cancer therapy. Because screening is costly, some have suggested that health-related quality of life (HRQL) measures might be useful in focusing screening tests on those patients with cases most likely to display positive findings. This study reports on the predictive ability of HRQL measures to detect patients with abnormalities on serial cardiac testing. METHODS: Using 127 patients from the ACE-Inhibitor after Anthracycline (AAA) Trial, this study compared serial measures of the Short Form-36 (SF-36; for ages > 13 years) and Child Health Questionnaire-Child Form 87 (CHQ-CF87; for ages < or = 13 years) to serial cardiac performance tests including echocardiographic shortening fraction, left ventricular end systolic wall stress (LVESWS), LVESWS-index, and maximal cardiac index (MCI; a measure of cardiac output at peak exercise). RESULTS: Generally, there was no clinically or statistically significant correlation between any HRQL measure and any cardiac function measure except between MCI and vitality and physical functioning. For each of these measures, the correlation between MCI was statistically significant (P < .006), but each HRQL subscale could explain no more than 7% of the variation in MCI. HRQL measures were not predictive of any other cardiac function measure. CONCLUSION: HRQL measures should not be used in isolation as a screen for cardiac function abnormalities in patients exposed to anthracylines who already have a mild degree of ventricular dysfunction. Patient history appears to be no substitute for cardiac testing in this cohort.

Doppler‐guided haemorrhoidal artery ligation in patients with Crohn’s disease

Aim: The outcome of Doppler‐guided haemorrhoidal artery ligation (DGHAL) was assessed in patients with Crohn’s disease (CD) suffering from grade III haemorrhoids. Method: A retrospective study was carried out of patients with CD and symptomatic Grade III haemorrhoids treated by DGHAL. Perioperative and follow‐up data were retrieved from our database of patients undergoing DGHAL. Results: The study included seven men and six women. The mean age was 34 years old. All had CD without anorectal involvement. The median duration of haemorrhoidal symptoms was 6.3 years. There was no mortality, new incontinence, faecal impaction, urinary retention, abscess formation or persistent pain following the procedure. Mean pain score based on a visual analogue scale (VAS) decreased from 2.4 at 24 h postoperatively to 1.6 on the seventh postoperative day. All patients had completely recovered by the third postoperative day. At 18 months, three (77%) of the patients were asymptomatic and three had recurrent symptoms. Conclusion: Doppler‐guided haemorrhoidal artery ligation is safe and effective in treating Grade III haemorrhoids in patients with CD without rectal involvement.     

Exhaled nitric oxide and asthma in young children

Exhaled nitric oxide (eNO) has been used to diagnose asthma in adults and children using either the slow vital capacity method (SVCm) or, in younger children, the tidal breathing method (TBm). Adenosine 5'-monophosphate (AMP) challenge also has been found to be a sensitive and specific test for the diagnosis of asthma. In the present study, we used the AMP provocation concentration that caused wheezing (PCW) to confirm the diagnosis of asthma (PCW < or = 200 mg/mL). We studied 36 children (2-7 years) with mild intermittent asthma, 13 children (3-7 years) with moderate persistent asthma treated with inhaled steroids, 20 nonasthmatic children (2-7 years) with chronic cough and recurrent pneumonia, and 15 healthy children (4-6 years). Expired gas was collected in collection bags by the TBm, and eNO was measured. We evaluated the efficacy of eNO values in diagnosing asthma. The mean eNO level of the mild intermittent asthmatic children (5.6 +/- 0.4 ppb) not receiving inhaled corticosteroids was significantly higher (ANOVA P < 0.0001) than that of the moderate persistent asthmatics who were treated with inhaled steroids, the nonasthmatic children with chronic cough, and the group of healthy children (3.7 +/- 0.6 ppb, P < 0.05; 3.2 +/- 0.3 ppb, P < 0.001; 2.2 +/- 0.2 ppb, P < 0.001, respectively). The points of intersection for sensitivity and specificity curves of eNO to differentiate mild intermittent asthmatics from nonasthmatic children with chronic cough and from healthy children were 77% and 88% for eNO values of 3.8 ppb and 2.9 ppb, respectively. We conclude that eNO collected by the TBm can differentiate steroid-naive young children with intermittent asthma from healthy children, from nonasthmatic children with chronic cough, and from asthmatic children treated with inhaled steroids.     

Exhaled nitric oxide is age-dependent in asthma

We determined whether the exhaled nitric oxide (eNO) level in asthmatics is age-dependent. Eighty-seven asthmatic patients aged 2-41 years were studied. Hyperreactivity to adenosine 5'-monophosphate (AMP) was used to confirm asthma (相似文献   

Therapieergebnisse der Stapler-H?morrhoidopexie versus der H?morrhoidenarterienligatur bei H?morrhoiden 3.?Grades

Purpose

The aim of the study was to evaluate the long-term results, early and late complication rates and overall satisfaction of patients with grade III hemorrhoids treated by stapled hemorrhoidopexy (SH) or doppler-guided hemorrhoidal artery ligation (DGHAL).

Methods

Operative and follow-up patient data were prospectively collected for patients undergoing either SH or DGHAL by a single surgeon during a 2-year period. A retrospective comparison between patient outcomes after operations by one of the two methods was made based on these data. Clinical data on postoperative pain, analgesic requirements, time to first bowel movement and functional recovery were collected at five postoperative follow-up visits (1 and 6 weeks, 6, 12, and 18 months). Data on patient satisfaction, recurrence of hemorrhoidal symptoms and further treatment were obtained from a standardized questionnaire completed during the last visit 18 months postoperatively.

Results

A total of 63 patients underwent SH (average age 52?±?3.2 years) and 51 patients underwent DGHAL (average age 50?±?7.3 years). The DGHAL patients experienced less postoperative pain as scored by pain during bowel movement (2.1?±?1.4 vs. 5.5?±?1.9 for SH), and required less postoperative analgesics. Hospital stay, time to first bowel movement and complete functional recovery were also significantly shorter for the DGHAL patients. A total of 9 DGHAL patients (18%) suffered from persistent bleeding or prolapse and required additional treatment compared with 2 (3%) patients in the SH group. The SH patients reported greater satisfaction compared with DGHAL patients at 1 year postoperatively.

Conclusions

Both SH and DGHAL are safe procedures and have similar effectiveness for treating grade III hemorrhoid;s however DGHAL is less painful and provides earlier functional recovery but is associated with higher recurrence rates and lower satisfaction rates compared with SH.     

Grading of complications and risk factor evaluation in laparoscopic colorectal surgery

Background

A grading system for postoperative complications is important for quality control and comparison among investigations. The objective of the current study was to evaluate complications associated with laparoscopic colorectal surgery according to a standardized grading system, and to examine risk factors associated with different complication grades.

Methods

Data of all patients who underwent elective laparoscopic colorectal surgery at two medical centers between September 2003 and January 2011 were collected prospectively. Complications were graded retrospectively into five categories based on a previously proposed grading system for colorectal operations. Age, gender, BMI, Charlson comorbidity score, indication for surgery, pathology site, conversion rate, learning curve, operative times, previous abdominal surgery, concurrent surgical procedures performed, and length of hospital stay were evaluated as risk factors and outcome measures for complications.

Results

A total of 501 patients were included in the study. Of them, 30.5 % suffered at least one complication and 6.5 % more than one. Complications that were mainly medical or surgical site infections requiring minor intervention (grades 1 and 2) occurred in 22.9 % of patients. Surgical complications requiring invasive interference (grades 3 and 4) occurred in 7.4 % of patients and mortality (grade 5) occurred in 0.2 % (1 patient). Length of hospital stay was directly related to complication grade. Average hospital stay was 6.8 ± 3.5, 10.5 ± 5.1, and 20.2 ± 12.3 days for patients with no complications, grade 1–2 complications, and grade 3–4 complications, respectively (p < 0.01). Minor complications (grades 1–2) were associated with conversion (p < 0.01), high Charlson score (p = 0.004), and additional surgical procedures (p = 0.04). Major complications (grades 3–4) were associated solely with conversion (p < 0.01) and rectal pathology (p < 0.01).

Conclusion

This study demonstrates the use of a uniform grading system for complications in laparoscopic colorectal surgery. Conversion was found to be associated with all grades of complications.
