RESUMEN

The separation of the two rectus abdominis muscles along the linea alba is termed diastasis of recti abdominis muscles (DRAM). DRAM is a common health problem in people that are both pregnant and postpartum. With a 100% frequency at gestational week 35, it is extremely frequent during pregnancy. Control and function of the trunk are greatly influenced by the musculature of the abdomen. The existence, extent, and duration of DRAM have been connected to low back and pelvic discomfort however the relationship is not conclusive. It has been proven to weaken abdominal muscles and impair their functioning in lumbo-pelvic stability. Additionally, DRAM has been linked to pelvic floor dysfunction. The mechanical control and function of the abdomen can be compromised by diastasis recti, which compromises the abdominal muscles. This study examined the impact of abdominal exercises and neuromuscular electrical stimulation on the DRAM in postnatal females who underwent Caesarean section. A total of 208 individuals, aged between 20 and 34, who had recti diastasis measuring more than 2.5 cm, underwent screening. They were split into two groups at random. Group B only received abdominal exercises, whereas Group A received NMES in addition to their activities. For a period of 12 weeks, the intervention was given to both groups three times a week. Changes have been recorded before and after the intervention. The pressure biofeedback unit, measuring tape, and vernier caliper were employed to evaluate the outcome measures of inter-recti distance, abdominal muscle strength, and waist-hip ratio, respectively. In every outcome, both groups had a highly significant (p<0.05) improvement. Furthermore, after 12 weeks, group A had improved in all measures with highly significant (p<0.05) intergroup comparisons. In comparison to MNES alone, NMES can have a more significant effect on reducing DRAM in postpartum women when paired with abdominal Exercise.

RESUMEN

OBJECTIVES: To develop guidelines describing a standardised approach to patient preparation and acquisition protocols for magnetic resonance imaging (MRI), computed tomography (CT) and ultrasound (US) of the small bowel and colon, with an emphasis on imaging inflammatory bowel disease. METHODS: An expert consensus committee of 13 members from the European Society of Gastrointestinal and Abdominal Radiology (ESGAR) and European Society of Paediatric Radiology (ESPR) undertook a six-stage modified Delphi process, including a detailed literature review, to create a series of consensus statements concerning patient preparation, imaging hardware and image acquisition protocols. RESULTS: One hundred and fifty-seven statements were scored for agreement by the panel of which 129 statements (82 %) achieved immediate consensus with a further 19 (12 %) achieving consensus after appropriate modification. Nine (6 %) statements were rejected as consensus could not be reached. CONCLUSIONS: These expert consensus recommendations can be used to help guide cross-sectional radiological practice for imaging the small bowel and colon. KEY POINTS: • Cross-sectional imaging is increasingly used to evaluate the bowel • Image quality is paramount to achieving high diagnostic accuracy • Guidelines concerning patient preparation and image acquisition protocols are provided.

RESUMEN

PURPOSE: To evaluate whether the extent of enteric diffusion-weighted imaging (DWI) signal abnormality reflects inflammatory burden in Crohn's disease (CD), and to compare qualitative and quantitative grading. METHODS: 69 CD patients (35 male, age 16-78) undergoing MR enterography with DWI (MRE-D) and the same-day faecal calprotectin (cohort 1) were supplemented by 29 patients (19 male, age 16-70) undergoing MRE-D and terminal ileal biopsy (cohort 2). Global (cohort 1) and terminal ileal (cohort 2) DWI signal was graded (0 to 3) by 2 radiologists and segmental apparent diffusion coefficient (ADC) calculated. Data were compared to calprotectin and a validated MRI activity score [MEGS] (cohort 1), and a histopathological activity score (eAIS) (cohort 2) using nonparametric testing and rank correlation. RESULTS: Patients with normal (grades 0 and 1) DWI signal had lower calprotectin and MEGS than those with abnormal signal (grades 2 and 3) (160 vs. 492 µg/l, p = 0.0004, and 3.3 vs. 21, p < 0.0001), respectively. Calprotectin was lower if abnormal DWI affected <10 cm of small bowel compared to diffuse small and large bowel abnormality (236 vs. 571 µg, p = 0.009). The sensitivity and specificity for active disease (calprotectin > 120 µg/l) were 83% and 52%, respectively. There was a negative correlation between ileal MEGS and ADC (r = -0.41, p = 0.017). There was no significant difference in eAIS between qualitative DWI scores (p = 0.42). Mean ADC was not different in those with and without histological inflammation (2077 vs. 1622 × 10-6mm2/s, p = 0.10) CONCLUSIONS: Qualitative grading of DWI signal has utility in defining the burden of CD activity. Quantitative ADC measurements have poor discriminatory ability for segmental disease activity.

RESUMEN

BACKGROUND: Magnetic resonance enterography (MRE) can measure small bowel motility, reduction in which reflects inflammatory burden in Crohn's Disease (CD). However, it is unknown if motility improves with successful treatment. AIM: To determine if changes in segmental small bowel motility reflect response to anti-TNFα therapy after induction and longer term. METHODS: A total of 46 patients (median 29 years, 19 females) underwent MRE before anti-TNFα treatment; 35 identified retrospectively underwent repeat MRE after median 55 weeks of treatment and 11 recruited prospectively after median 12 weeks. Therapeutic response was defined by physician global assessment (retrospective group) or a ≥3 point drop in the Harvey-Bradshaw Index (prospective group), C-reactive protein (CRP) and the MaRIA score. Two independent radiologists measured motility using an MRE image-registration algorithm. We compared motility changes in responders and nonresponders using the Mann-Whitney test. RESULTS: Anti-TNFα responders had significantly greater improvements in motility (median = 73.4% increase from baseline) than nonresponders (median = 25% reduction, P < 0.001). Improved MRI-measured motility was 93.1% sensitive (95%CI: 78.0-98.1%) and 76.5% specific (95% CI: 52.7-90.4%) for anti-TNFα response. Patients with CRP normalisation (<5 mg/L) had significantly greater improvements in motility (median = 73.4% increase) than those with persistently elevated CRP (median = 5.1%, P = 0.035). Individuals with post-treatment MaRIA scores of <11 had greater motility improvements (median = 94.7% increase) than those with post-treatment MaRIA score >11 (median 15.2% increase, P = 0.017). CONCLUSIONS: Improved MRI-measured small bowel motility accurately detects response to anti-TNFα therapy for Crohn's disease, even as early as 12 weeks. Motility MRI may permit early identification of nonresponse to anti-TNFα agents, allowing personalised treatment.

RESUMEN

AIM: To describe our experience using a 5 year audit of computed tomography colonography (CTC) practice and identify factors that influence diagnostic performance to guide implementation in other centres. MATERIAL AND METHODS: Consecutive patients referred for CTC at a single institution over a 5 year period were identified, and reporting rates and positive predictive value (PPV) calculated for small polyps, large polyps, and colorectal cancer. Diagnostic performance was compared using the Chi-squared test, and trends over time were examined with logistic regression. The effect of faecal tagging and an intravenous spasmolytic were investigated using Fisher's exact test. RESULTS: In total, 4355 CTC examinations were performed. Overall reporting rates and PPV were 17% and 92%, respectively. Negative predictive value (NPV) for cancer was 99.9%. A significant decrease in reporting rate (p < 0.001) was accompanied by an increase in PPV for small polyps (p = 0.02) following the introduction of faecal tagging. Adequacy rates for CTC improved over time (96% to 99%), with improved adequacy rates when using a spasmolytic, 98% versus 96% without. A significant difference in reporting rates, but not PPV, was found between radiologists. CONCLUSION: Accurate colonic investigation using CTC can be delivered safely to a high-risk patient population at a single centre. Faecal tagging and an intravenous spasmolytic improve diagnostic performance.

RESUMEN

There have been numerous advances in the field of cardiac imaging. The advent of multidetector computed tomography coronary angiography (MDCT-CA) and in particular electrocardiographic (ECG)-gated acquisition has revolutionized the investigation of the complete spectrum of complications of common cardiothoracic surgical procedures. Generic complications, such as mediastinitis, pericardial effusion, sternal osteomyelitis, and mediastinal fibrosis, are discussed with illustrative examples of multiplanar and volume-rendered three-dimensional reconstructions. Graft-related complications of both coronary artery bypass grafts and aortic root grafts are reviewed. The role of MDCT-CA in the investigation of prosthetic valve endocarditis and root abscesses is outlined. We present a complete illustration of the detailed images that are obtained when investigating a full range of graft-related complications from both aortic and coronary surgery using ECG-gated MDCT-CA. MDCT-CA has the potential to become established as the optimal technique with which to image a multitude of complications post-cardiac surgery.

RESUMEN

Pancreatic and biliary disease continues to have a significant impact on the workload of the National Health Service (NHS), for which there exists a multimodality approach to investigation and diagnosis. Endoscopic ultrasound (EUS) is fast becoming a fundamental tool in this cohort of patients, not only because of its ability to provide superior visualization of a difficult anatomical region, but also because of its valuable role as a problem-solving tool and ever-improving ability in an interventional capacity. We provide a comprehensive review of the benefits of EUS in everyday clinical practice.

RESUMEN

OBJECTIVE: oral sedation is the simplest and most convenient sedation method for managing uncooperative child patients because it is easy to administer and there is no need for nasal hood or injection. Oral midazolam is the most commonly used preanesthetic medication for children. When given in amounts between 0.5 and 0.75 mg/kg of body weight, oral midazolam has been found to be an effective sedative agent for pediatric outpatients. Tramadol is a synthetic, centrally acting analgesic indicated for moderate to severe pain. Chloral hydrate is one of the sedatives most commonly used, has excellent absorption, fast induction, and exert minimal effects on respiration. zolpidem is the most commonly prescribed hypnotic due to its clinical efficacy, safety, and ability to be well tolerated with patients. MATERIALS AND METHODS: 60 anxious and fearful children who reported to the department were treated under conscious sedation for the accomplishment of dental treatment. Patients were randomly assigned to four groups. Statistical analysis was done using Kruskal Wallis Test and decision criterion was to reject the null hypothesis if the P-value is less than 0.05. RESULTS: it was observed that there is a statistically significant difference in median scores recorded for the level of sedation between the different groups (P < 0.001). CONCLUSION: this study concluded that midazolam is the best drug for producing conscious sedation followed by tramadol and triclofos. Zolpidem was not able to produce a sufficient level of sedation and it cannot be supported as a sedative agent at the present dosage.

RESUMEN

Renal Cell Carcinoma (RCC) is a malignant tumor occurring in 5th-6th decade of life with an increasing incidence reported in the US but stable in Europe. The metastasis of RCC to head and neck region is infrequent and very rarely seen in larynx. Very few cases of RCC metastasizing to larynx are reported in literature. We report a case of RCC in a middle aged male with metastasis to larynx, 7 years after initial diagnosis and nephrectomy. These unusual tumor metastases have unique pathobiology and route of metastasis, and there can be a long interval from initial diagnosis of primary tumor. The diagnosis of metastatic RCC in unusual locations is often not easy. Treatment options include metastasectomy, radiotherapy and systemic chemotherapy but with a poor outcome. A differential diagnosis should always be considered in metastatic head and neck tumors. The need for prompt accurate diagnosis, risk stratification at initial primary diagnosis, surveillance, and long term regular follow up is emphasized.

RESUMEN

Focal fat infiltration and focal fat sparing of the liver are less common than diffuse fat infiltration but present a greater diagnostic conundrum. Although typical features of these conditions are well described, there is a wide variety of different appearances. These atypical patterns present significant difficulty in differentiation from other pathological processes and often require additional investigation. We present an innovative diagnostic algorithm and illustrate its effectiveness in diagnosing focal fatty liver disease with typical and atypical examples.

RESUMEN

Although, the diagnosis and evaluation of sarcoidosis has traditionally remained confined to the chest, its multi-system nature has been widely recognized. Radiological features of pulmonary sarcoidosis are well known but extra-pulmonary manifestations can produce a plethora of non-specific imaging findings that can affect subcutaneous tissue, and the neurological, cardiac, gastrointestinal, urological, liver, spleen, and skeletal systems. In the literature, there are various case reports and specific system reviews but there are few reviews that encompass all the extra-pulmonary manifestations. In this paper, we comprehensively review the imaging features of extra-pulmonary sarcoidosis with characteristic features as well as atypical presentations. In addition, we discuss the emerging role of nuclear medicine in sarcoidosis.

RESUMEN

AIM: To examine the productivity (both economic and otherwise) of trainees within a radiology department at our institution. MATERIALS AND METHODS: Productivity was measured in three ways: (1) independent workload contribution, (2) impact on on-call services, and (3) impact on day-to-day practice as perceived by consultant radiologists. Data were collected using retrospective searches on computerized radiology information system (CRIS), analysis of trainees and consultant rotas, and a questionnaire to consultants and trainees. Where possible, productivity was quantified in terms of number of programmed activities (PAs). RESULTS: The contribution of independent work by trainees in a single week was 52.75 PAs (or 1.45 PAs per trainee per week). In addition, the on-call contribution was 23.1 PAs per week (or 0.93 PAs per trainee per week). When both trainees and consultants report independently, productivity in a single list in most cases increased and can be as much as 197%. On calculating the economic impact, this amounts to significant savings of around £1.2million per year at our institution. CONCLUSION: Based upon objectively measurable areas of service provision, the employment of trainees yields considerable economic benefit. Furthermore, based upon qualitative methods we have shown that trainees contribute positively in those areas, which are much harder to quantifiably evaluate. These are benefits in addition to fundamental requirement to train future competent radiologists.

RESUMEN

The authors present an unusual cause of pneumocephalus in a previously fit and well female octogenarian who presented with acute onset altered level of consciousness and generalised weakness. Radiological imaging demonstrated widespread cerebritis with pneumocephalus and gas within the superior sagittal sinus. Blood culture grew Clostridium septicum, a virulent but rare organism that can infect normal tissues. The close association between C septicum and both haematological and bowel malignancies must be considered if this organism is cultured.

RESUMEN

Primary benign tumours of the heart are rare, with myxomas being the commonest. They are neoplasms of endocardial origin and generally appear to grow rapidly. The presence of connective tissue fibers encrusted with iron and calcium known as Gamna Gandy bodies may indicate a longer duration of tumor. We present a case of cardiac myxoma with Gamna Gandy bodies, which is an infrequent finding, and briefly review relevant literature.

RESUMEN

BACKGROUND: Off-pump coronary artery bypass (OPCAB) surgery has been successfully used in diverse patient populations and has been postulated to be safer than conventional coronary artery bypass (CCAB) surgery in some high-risk patients, including the elderly. OBJECTIVE: To compare the safety of OPCAB surgery versus CCAB surgery in the octogenarian population of two large southwestern Ontario cardiac surgical units. RESULTS: Two hundred thirty-six consecutive octogenarians underwent primary isolated coronary artery bypass surgery from November 2000 to March 2005. Patients undergoing OPCAB surgery tended to have higher Parsonnet scores, while patients undergoing CCAB surgery had a greater number of emergent operations. The Canadian Cardiovascular Network predicted that mortality risk was similar in both groups. In-hospital mortality was similar between groups, as was postoperative myocardial infarction and new onset of renal dysfunction. However, in the OPCAB group, there was a decreased incidence of postoperative neurological dysfunction (2.3% in the OPCAB group versus 10.5% in the CCAB group, P=0.01), in particular cerebrovascular accidents (1.5% in the OPCAB group versus 7.6% in the CCAB group, P=0.05), and a decreased incidence of prolonged intubation (5.3% in the OPCAB group versus 13.3% in the CCAB group, P=0.04). Multivariable analysis found that cardiopulmonary bypass had no significant impact on mortality or length of stay. CONCLUSIONS: In octogenarian patients, OPCAB surgery is as safe as CCAB surgery in terms of mortality and major morbidity. Furthermore, a significant reduction in neurological dysfunction and prolonged intubation was seen in the OPCAB group compared with the CCAB group.

RESUMEN

BACKGROUND: Although use of the internal thoracic artery has been shown to improve outcomes after coronary artery bypass grafting, the same cannot be said of alternative arterial conduits. To determine the benefit of radial artery (RA) grafting, a case-matched review was undertaken. METHODS: Between March 1994 and March 1999, 2,847 patients underwent isolated coronary artery bypass grafting with a left internal thoracic artery graft, plus saphenous vein grafts (SVGs). Of these patients, 478 also received an RA graft (RA group). The RA patients were matched at a ratio of 1:2 with patients receiving only SVGs and a left internal thoracic artery graft (SVG group; n = 956) using six prognostic risk factors: age, sex, Canadian Cardiovascular Society class, left ventricular grade, number of diseased vessels, and timing of operation. Target vessels were graded according to quality and graftability and were similar between groups. Outcomes were evaluated by univariate and multivariate analyses. RESULTS: There was a significantly higher prevalence of diabetes, hypertension, and peripheral vascular disease in the RA group (p < 0.05). Although stay in the intensive care unit was shorter in the RA group (RA, 30 +/- 2 hours, and SVG, 37 +/- 2 hours; p = 0.0002), total hospital stay was similar between groups. The incidence of perioperative myocardial infarction was higher in the SVG group (SVG, 31 of 956 or 3.2%, and RA, 6 of 478 or 1.3%; p = 0.02). Multivariate analysis revealed RA grafting to be protective against early mortality and morbidity (odds ratio = 0.58; 95% confidence interval, 0.37 to 0.90; p = 0.015) and late mortality and morbidity including late reintervention (risk ratio = 0.60; 95% confidence interval, 0.37 to 0.93; p = 0.02). Actuarial freedom from events at 36 months postoperatively was greater in the RA group (RA, 95% +/- 2%, and SVG, 86% +/- 4%; p = 0.01). CONCLUSIONS: Despite a higher prevalence of preoperative comorbidity, patients in the RA group demonstrated improved outcomes after coronary artery bypass grafting. The RA is a viable and beneficial conduit for this operation.

RESUMEN

Malakoplakia is a rare disease expressed as a special type of inflammatory reaction to infection with various bacteria and fungi. We present a case of renal malakoplakia in a 30-year-old female patient. The symptoms were not characteristic enough for making the ture diagnosis preoperatively. A preoperative diagnosis of renal cell carcinoma was made in this case.

RESUMEN

BACKGROUND: To assess the impact of gender as an independent risk factor for early and late morbidity and mortality following coronary artery bypass surgery. METHODS: Perioperative and long-term data on all 4,823 patients undergoing isolated coronary bypass operations from November 1989 to July 1998 were analyzed. Of these patients, 932 (19.3%) were females. RESULTS: During the years 1989 to 1998 there was a progressive increase in the percentage of women undergoing coronary artery bypass surgery. The following preoperative risk factors were more prevalent among women than men: age above 70, angina class 3 or 4, urgent operation, preoperative intraaortic balloon pump usage, congestive heart failure, previous percutaneous transluminal coronary angioplasty, diabetes, hypertension, and peripheral vascular disease (all p < 0.05). Men were more likely to have an ejection fraction less than 35%, three-vessel disease, repeat operations, and a recent history of smoking. Women had a statistically significant smaller mean body surface area than men (1.72+/-0.18 versus 1.96%+/-0.26% m2). On average, women had fewer bypass grafts constructed than men (2.9%+/-0.8% versus 3.2%+/-0.9%) and were less likely to have internal mammary artery grafting (76.2% versus 86.1%), multiple arterial conduits (10.1% versus 19.8%), or coronary endarterectomy performed (4.9% versus 8.6%). The early mortality rate in women was 2.7% versus 1.8% in men (p = 0.09). Women were more prone to perioperative myocardial infarction (4.5% versus 3.1% p < 0.05). After adjustment for other risk variables, female gender was not an independent predictor of early mortality but was a weak independent predictor for the prespecified composite endpoint of death, perioperative myocardial infarction, intraaortic balloon counterpulsation pump insertion, or stroke (8.55 versus 5.9%; odds ratio, 1.30; 95% confidence interval, 0.99 to 1.68; p = 0.05) Recurrent angina class 3 or 4 was more frequent in female patients (15.2%+/-4.0% versus 8.5%+/-2.0% at 60 months, p = 0.001) but not repeat revascularization procedures (percutaneous transluminal coronary angioplasty, redo) (0.6%+/-0.3% versus 4.1%+/-0.8% at 60 months). Actuarial survival at 60 months was greater in women then men (93.1%+/-1.7% versus 90.0%+/-1.0%), and after adjustment for other risk variables, female gender was protective for late survival (risk ratio, 0.40; 95% confidence interval, 0.16-0.74; p < 0.005). CONCLUSIONS: Perioperative complications were increased and recurrent angina more frequent in women. Despite this, late survival was increased in women compared with men after adjustment for other risk variables

RESUMEN

BACKGROUND: The demographics of patients undergoing coronary artery bypass grafting (CABG) have changed over time and may contribute to differing operative mortality and the combination of mortality and morbidity (M + M). In this study, the trends in results are analyzed and causes are suggested. METHODS: Prospectively collected data concerning 4,839 CABG operations was divided into three time cohorts (1990 to 1992, 1993 to 1995, 1996 to 1998) and analyzed by univariate and multivariate techniques. RESULTS: Mean age and female gender frequency increased in the later time cohorts (60.7 +/- 9.0 to 63.4 +/- 9.9 years and 16.5% to 21.4%, respectively). The following comorbidities were more prevalent in the later time cohorts: diabetes (26.7% versus 18.6%), renal failure (8.5% versus 2.2%), peripheral vascular disease (20.7% versus 11.0%), previous cerebrovascular accident (6.7% versus 5.0%), urgent procedures (41.5% versus 26.9%), unstable angina (47.8% versus 31.7%), urgent CABG following myocardial infarction (17.1% versus 7.3%), previous percutaneous transluminal coronary angioplasty (8.0% versus 4.5%), ejection fraction less than 35% (20.5% versus 10.4%), (all p < 0.05). Procedurally, increased utilization of the left internal mammary artery, multiple arterial conduits, and warm blood cardioplegia occurred in the later cohorts (91.2%, 22.2%, and 80.4% versus 78.7%, 3.4%, and 38.0%, respectively). The mortality rate was 2.0% and the M + M rate was 15.6% in all 4,839 patients. The mortality and M + M for the three cohorts were 1.6%, 2.0%, and 2.3% and 18.4%, 17.2% and 12.5%, respectively. The risk-adjusted mortality and M + M decreased from 2.4% and 15.9%, respectively, in 1990 to 1992 to 1.8% and 8.4% in 1996 to 1998 (p < 0.001). The difference in adjusted event rates was minimized when the surgical factors were entered into the model. CONCLUSIONS: Over time, there has been a trend toward operating on older patients with more comorbidities. Though hospital mortality has been stable, risk-adjusted M + M has been in a constant decline. This decline was associated with an increased use of left internal mammary artery grafts, multiple arterial conduits, and warm blood cardioplegia during the later years of the study.
