Endovascular suitability and outcome after open surgery for ruptured abdominal aortic aneurysm

Endovascular repair of ruptured abdominal aortic aneurysm (rAAA) has rapidly gained popularity, but superior results may be biased by patient selection. The aim was to investigate whether suitability for endovascular repair predicted survival, irrespective of technique of repair.

Burden of abdominal obesity in cardiac rehabilitation patients: Results from the Swiss CaRe study

BACKGROUND: The burden of abdominal obesity (AO) and its association with other cardiovascular risk factors is not known in coronary artery disease (CAD) patients attending cardiac rehabilitation (CR). The aim of this study was, therefore, to investigate the prevalence of AO and differences in cardiovascular risk factors between AO and non-AO patients. METHODS: 415 consecutive male CAD patients (mean age 58 ± 11 years) attending a three-month outpatient CR programme were assessed. Differences in cardiovascular risk profile, including blood lipids, psychosocial and socioeconomic status and exercise capacity, were compared in relation to AO and corrected for obesity measured by body-mass index (BMI) in a multivariate analysis. RESULTS: Mean waist circumference was 102 ± 11 cm. Patients of lower educational level had a higher prevalence of AO (p = 0.021) than patients with a higher educational level. AO was significantly associated with diabetes (p = 0.003) and hypertension (p <0.001). In AO patients, HDL-C levels were lower (p <0.001) and triglyceride levels higher (p = 0.006) than in non-AO patients. There was no difference in exercise capacity between AO and non-AO patients, but AO patients had a higher resting heart rate (p = 0.021). CONCLUSION: AO is highly prevalent in CAD patients attending CR. AO is, independently of BMI, associated with metabolic lipid disorders and autonomic cardiovascular dysregulation, suggesting an increased cardiovascular risk. AO patients therefore need particular attention during CR and follow-up care.

Spa-drain entrapment complicated by suspicions of nonaccidental trauma and epilepsy onset

We present here the case of an adolescent female near-drowning victim who was reportedly discovered submerged and unconscious by family members in a whirlpool spa. Physical examination revealed extensive posterior soft tissue bruising, which raised the suspicion of nonaccidental trauma. Detailed forensic evaluation of the injuries and the scene proved that the soft tissue findings represented an unusual manifestation of whirlpool-spa suction-vent injury. Medical evaluation indicated that epilepsy onset might have contributed to the near-drowning, although forensic evaluation of this possibility was less convincing. In this article we review these rare but important injuries, which have the potential to be confused with child abuse, and detail the atypical presentation and clinically presumed etiologic event in our case.

[Abdominal pain in the general doctor's practice]

Abdominal pain is a frequent symptom and in the majority of cases the underlying disease is not life threatening. The general practitioner's first task is to differentiate between inflammatory and other diseases. The patient's history, the clinical examination and laboratory tests form the basis for the differential diagnosis. A sonography is the first additional examination in the vast majority of the cases. Accidentally found gallstones usually do not require surgical intervention. Surgery in asymptomatic patients should be limited to gallbladder polyps and patients with calcifications in their gallbladder wall.

Ignoring non-specific abdominal pain in emergency department patients may be related to decreased quality of life. A follow up of an underestimated problem

Patients suffering from chronic pain have a high prevalence of depression, resulting in a significant impact on overall quality of life. Our aim was to investigate how long term acute non-specific abdominal pain (NSAP) affected overall physical and mental well-being in patients admitted to our emergency department (ED).

[Abdominal pain - differential diagnoses and diagnostic strategies in patients with chronic symptoms]

Abdominal pain is a very common complaint in a primary care consultation. The causes of abdominal pain are extremely diverse and range from conditions that require urgent surgical remedy to those without serious underlying pathology where the problem either settles spontaneously, or becomes chronic without any abnormalities on laboratory or clinical workup. While tests are helpful in confirming diagnoses, clinical judgement based on a careful history and physical examination remains extremely important in choosing from the extremely wide differential diagnoses and in the management of the condition. In this article, we will deal with chronically recurrent intermittent abdominal pain. Our aim is especially to provide guidance on the possibility that abdominal pain is a symptom of chronic inflammatory bowel disease (IBD) or an identifiable functional condition and when the diagnosis of irritable bowel syndrome should be made.

[Functional abdominal pain]

Functional abdominal pain is an inhomogeneous group of disorders concerning aetiology and clinical presentation. Support for classification is provided by the ROME-Foundation with its criteria catalogue, ROME-III being the most recent one. However, basic approach consists of exclusion of somatic or psychiatric as well as psychosomatic disorders that are sharply defined and readily diagnosable. This article outlines a pragmatic gastroenterological approach by exemplary means of dyspepsia and irritable bowel syndrome. Dyspepsia includes a broad complex of mainly epigastric located symptoms, whereas irritable bowel syndrome is symptomatic with altered bowel habits and mid-abdominal pain in the majority. Gastreoenterologic therapy modalities are mainly based on empirical and symptomatic grounds, more than on precisely explaining pathophysioligic understanding.

Brain infiltration of leukocytes contributes to the pathophysiology of temporal lobe epilepsy

Clinical and experimental evidence indicates that inflammatory processes contribute to the pathophysiology of epilepsy, but underlying mechanisms remain mostly unknown. Using immunohistochemistry for CD45 (common leukocyte antigen) and CD3 (T-lymphocytes), we show here microglial activation and infiltration of leukocytes in sclerotic tissue from patients with mesial temporal lobe epilepsy (TLE), as well as in a model of TLE (intrahippocampal kainic acid injection), characterized by spontaneous, nonconvulsive focal seizures. Using specific markers of lymphocytes, microglia, macrophages, and neutrophils in kainate-treated mice, we investigated with pharmacological and genetic approaches the contribution of innate and adaptive immunity to kainate-induced inflammation and neurodegeneration. Furthermore, we used EEG analysis in mutant mice lacking specific subsets of lymphocytes to explore the significance of inflammatory processes for epileptogenesis. Blood-brain barrier disruption and neurodegeneration in the kainate-lesioned hippocampus were accompanied by sustained ICAM-1 upregulation, microglial cell activation, and infiltration of CD3(+) T-cells. Moreover, macrophage infiltration was observed, selectively in the dentate gyrus where prominent granule cell dispersion was evident. Unexpectedly, depletion of peripheral macrophages by systemic clodronate liposome administration affected granule cell survival. Neurodegeneration was aggravated in kainate-lesioned mice lacking T- and B-cells (RAG1-knock-out), because of delayed invasion by Gr-1(+) neutrophils. Most strikingly, these mutant mice exhibited early onset of spontaneous recurrent seizures, suggesting a strong impact of immune-mediated responses on network excitability. Together, the concerted action of adaptive and innate immunity triggered locally by intrahippocampal kainate injection contributes seizure-suppressant and neuroprotective effects, shedding new light on neuroimmune interactions in temporal lobe epilepsy.

New-onset epilepsy: considerations for initial and follow-up MRI to detect brain tumor

Seizures are often the presenting symptoms of a cerebral tumor and may precede its diagnosis by many years. The article under evaluation searched two large English registries for patients admitted for new-onset epilepsy. The risk of subsequently being diagnosed with a malignant brain tumor was found to be 26-fold higher compared with controls, persisted over many years and was accentuated in young patients. Recently, surgical advances have led to a significant decrease in surgical morbidities, making surgery the first treatment option for gliomas, especially low-grade gliomas. This paradigm shift warrants a consequent diagnostic workup (MRI) in patients at risk for low-grade glioma - that is, patients with new-onset epilepsy. The study is discussed in the context of the ongoing debate on neuroimaging after new-onset epilepsy.

[Adhesions and abdominal pain]

Adhesions occur with a high incidence after intra-abdominal surgery but can also develop due to infections, radiation or for idiopathic reasons. The formation of adhesions is initiated by tissue damage and is the result of peritoneal tissue repair involving the activation of the inflammatory system and the coagulation cascade. Acute small bowel obstruction is one of the most common complications and should be diagnosed rapidly using clinical examination and radiological imaging. A complete obstruction is life threatening and in a high percentage of patients requires rapid surgical intervention by laparotomy or laparoscopy depending on the clinical situation and the patients history. Despite numerous investigations, there is no reliable, commonly used method to prevent intra-abdominal adhesions. Minimizing tissue damage and foreign body exposure, avoiding spillage of intestinal and biliary contents as well as a laparoscopic approach seem to have a beneficial effect on the formation of intra-abdominal adhesions.

[The abdominal catastrophe]

Patients with an abdominal catastrophe are in urgent need of early, interdisciplinary medical help. The treatment plan should be based on medical priorities and clear leadership. First priority should be given to achieve optimal oxygenation of blood and stabilization of circulation during all treatment-phases. The sicker the patient, the less invasive the (surgical) treatment should to be, which means "damage control only". This short article describes 7 important, pragmatic rules that will help to increase the survival of a patient with an abdominal catastrophe. Preexisting morbidity and risk factors must be included in the overall risk-evaluation for every therapeutic intervention. The challenge in patients with an abdominal catastrophe is to carefully balance the therapeutic stress and the existing resistance of the individual patient. The best way to avoid abdominal disaster, however, is its prevention.

Effects of Aerobic Versus Resistance Exercise Without Caloric Restriction on Abdominal Fat, Intrahepatic Lipid, and Insulin Sensitivity in Obese Adolescent Boys: A Randomized, Controlled Trial

The optimal exercise modality for reductions of abdominal obesity and risk factors for type 2 diabetes in youth is unknown. We examined the effects of aerobic exercise (AE) versus resistance exercise (RE) without caloric restriction on abdominal adiposity, ectopic fat, and insulin sensitivity and secretion in youth. Forty-five obese adolescent boys were randomly assigned to one of three 3-month interventions: AE, RE, or a nonexercising control. Abdominal fat was assessed by magnetic resonance imaging, and intrahepatic lipid and intramyocellular lipid were assessed by proton magnetic resonance spectroscopy. Insulin sensitivity and secretion were evaluated by a 3-h hyperinsulinemic-euglycemic clamp and a 2-h hyperglycemic clamp. Both AE and RE prevented the significant weight gain that was observed in controls. Compared with controls, significant reductions in total and visceral fat and intrahepatic lipid were observed in both exercise groups. Compared with controls, a significant improvement in insulin sensitivity (27%) was observed in the RE group. Collapsed across groups, changes in visceral fat were associated with changes in intrahepatic lipid (r = 0.72) and insulin sensitivity (r = -0.47). Both AE and RE alone are effective for reducing abdominal fat and intrahepatic lipid in obese adolescent boys. RE but not AE is also associated with significant improvements in insulin sensitivity.
