Water and wastewater CFD and validation: are we losing the balance?

A literature screening on computational fluid dynamics (CFD) modelling in water treatment applications showed a vast range of validation ranging from no validation at all, over residence time distribution (RTD) and tracer testing, to velocity field, species concentration and, finally, turbulence properties measurements. The validation level also differs depending on process scale (laboratory, pilot, full) and type of system (rheology, single phase vs. multiphase). Given the fact that CFD is in more widespread use, a discussion on the extent and need of validation needs to be initiated. This paper serves as a discussion starter on the topic.

Conventional versus Rosemont endoscopic ultrasound criteria for chronic pancreatitis: interobserver agreement in same day back-to-back procedures.

BACKGROUND AND STUDY AIMS: Endoscopic ultrasound (EUS) is a commonly used and fairly sensitive method of assessing changes of chronic pancreatitis (CP) when routine noninvasive imaging has not shown overt features of CP. The aim of this study is to evaluate the interobserver agreement (IOA) for the classic (MSC) and the Rosemont (RC) criteria for the diagnosis of chronic pancreatitis on the basis of clinical practice. PATIENTS AND METHODS: Two experienced endosonographers evaluated on the same day patients referred for EUS in a blinded fashion. Data from the sonographic criteria of both MSC and RC were collected. Agreement was calculated using k statistics. RESULTS: A total of 69 patients were evaluated. The study population included mainly patients without pancreatic diseases, resulting in a low number of sonographic findings. Agreement for the final diagnosis was moderate for both classification systems of chronic pancreatitis (k = 0.53 for conventional and k = 0.46 for Rosemont). CONCLUSIONS: The IOA of EUS in the diagnosis of CP is moderate. The concordance values obtained in clinical practice are similar to those obtained in multicenter studies. The RC does not seem to improve the IOA of MSC.

Clinical impact of high-definition endoscopic ultrasonography (EUS) in a district hospital.

OBJECTIVES: Evaluation of the impact of EUS in clinical practice. METHODS: All exploration performed during the first 18 months of implementation of the technique were analyzed. Agreement was assessed by radiographic techniques or surgical specimens in those cases allowed. RESULTS: 277 exploration were performed. There have been only 2 complications and they were related to sedation in both cases. The demand increased gradually, reaching 70 scans per 100,000 inhabitants. Main indications were bile (34.3%) and pancreatic processes. No pathology was found in 10% of cases; 29 cases had choledocholithiasis (93% confirmed and treated endoscopically). Chronic pancreatitis was diagnosed in 19 cases (only 15.78% of the cases were diagnosed by computed tomography). 32 patients with idiopathic acute pancreatitis were evaluated: 20 of them had evidence of microlithiasis (80% cholecystectomized and asymptomatic after a mean follow-up of 21.5 months), two cases of choledocholithiasis, 1 with chronic pancreatitis and 9 cases remained free of filial etiology. We performed 56 punctures: 39 samples of pancreas in 33 patients (81.1% of the samples were diagnostic; adenocarcinoma and serous cystadenoma were the most common diagnoses), 13 enlarged nodes and 4 abdominal masses. CONCLUSIONS: EUS is a growing demand technique that has low risks and leads to better decision-making in a significant number of patients with different diseases. Therefore, its inclusion in routine clinical practice must be considered.

[Evolution and treatment response in microscopic colitis]. / Curso evolutivo y respuesta al tratamiento de las colitis microscópicas.

AIM: To study the clinical characteristics, treatment response and evolution in patients with microscopic colitis. MATERIAL AND METHODS: We performed a retrospective analysis of 24 patients (15 with collagenous colitis and 9 with lymphocytic colitis). Clinical and diagnostic features, treatment response and evolution according to the presence of maintenance therapy were evaluated. RESULTS: The mean age of the patients was 59.7 years and most were male. Nine patients took non-steroidal anti-inflammatory drugs (NSAID). No significant association was found with other drugs. Four patients presented associated rheumatological disease. Most patients presented insidious-onset diarrhea without pathological products, which was frequently associated with other symptoms (abdominal pain, bloating, weight loss, asthenia, tenesmus, and incontinence). Seven patients showed a slight increase in globular sedimentation rate. Fat in stools and radiological investigations (transit and opaque enema) were normal in patients who underwent these tests. Endoscopy revealed non-specific alterations in 42% of the patients while results were normal in the remaining patients. One patient showed clinical improvement on withdrawal of NSAIDs and 4 patients improved spontaneously. Clinical response was achieved in 7 of 13 patients treated with antimotility drugs, in 8 of 9 patients treated with salicylates, in 3 treated with oral corticoids, in 1 treated with cholestyramine and in 1 treated with topical budesonide. Nineteen patients required no maintenance therapy, 4 were administered salicylates and 1 was administered cholestyramine. After a mean follow-up of 42 months, evolution was chronic and intermittent in 14 patients and chronic and continuous in 1; 9 patients presented a single episode. No significant differences were found between patients administered maintenance therapy and those who were not or between collagenous colitis and lymphocytic colitis in the parameters analyzed. CONCLUSIONS: Microscopic colitis constitutes a group of diseases characterized by chronic diarrhea, few systemic effects and minimal radiological and/or endoscopic alterations. Evolution is characterized by recurrent episodes, with good response to treatment with cholestyramine, salicylates or corticoids when required.

[Autoimmune hepatitis with prolonged IGM antibodies to HAV. Are serological markers reliable in ruling out a diagnosis of autoimmune hepatitis?]. / Hepatitis autoinmune con positividad mantenida al IgM VHA. Son los marcadores serológicos fiables para descartar el diagnóstico de la hepatitis autoinmune?

We present the case of a 44-year-old woman who was referred to us for jaundice, choluria and acholia. Review of the patient's clinical history revealed that tests for hepatitis A virus (HAV) IgM antibody had been positive 4 and 2 years previously and continued to be so. The patient showed a score of 16 in the International Autoimmune Hepatitis Group's system when the HAV marker was not taken into account and a score of 13 when this marker was taken into account. The persistence of this viral marker for so many years in such patients is probably associated with polyclonal hypergammaglobulinemia. Consequently, we believe that the inclusion of this antibody as a negative datum in the diagnosis of autoimmune virus should be viewed with caution.

[Collagenous colitis: an entity with diverse therapeutic options]. / Colitis colágena: una entidad con diversas opciones terapéuticas.

Collagenous colitis is a disorder which has been diagnosed with increasing frequency in the last few years, probably due to the routine obtention of colon biopsy specimens in the study of patients with chronic diarrhoea. Good responses have been reported with a number of therapies, although only a scarce number of clinical trials have been performed, partly because of the small number of patients studied. Two cases of collagenous colitis with different therapeutic approaches are here reported. All medical therapy options for this interesting disorder are reviewed.

[Idiopathic chronic pancreatitis (with diffuse stenosis of Wirsung's duct) in ulcerative colitis]. / Pancreatitis crónica idiopática (con estenosis difusa del Wirsung) en la colitis ulcerosa.

We describe a case of chronic idiopathic pancreatitis associated with ulcerative colitis. Pancreatitis is a rare extra-intestinal manifestations of inflammatory bowel disease. Chronic idiopathic pancreatitis associated with ulcerative colitis are usually painless, without calcification, with stricture of the main pancreatic duct and with severe exocrine pancreatic insufficiency.

Epidural anesthesia in a patient with single ventricle.

BACKGROUND AND OBJECTIVES: Single ventricle is a complex congenital cardiopathy characterized by a unit ventricular chamber. Changes of the cardiovascular system in response to epidural anesthesia in these patients have yet to be clearly elucidated. METHODS: A 26-year-old man with single ventricle underwent an orchiopexy under lumbar epidural anesthesia with intravenous sedation. RESULTS: Orchiopexy was successfully performed and the patient was discharged from hospital 4 days later. CONCLUSION: This case report emphasizes the issues of importance to anesthesiologists in regard to this cardiopathy and describes a successful technique of caring for a patient with a complex problem in an emergency situation.

Post-traumatic transient cortical blindness.

Five patients: three children, one adolescent, and one young adult, examined in an emergency room setting were diagnosed with post-traumatic transient cortical blindness. This syndrome is characterized by transient visual loss, normal pupillary response and normal funduscopic examination following minor head trauma. In each case, vision returned to normal within minutes to hours following injury, leaving no neurological sequelae. Headache, confusion, irritability, anxiety, nausea and vomiting were the most common related symptoms. While the mechanism responsible for the transient blindness is unknown, most authors propose an abnormal vascular response to trauma with resultant transient hypoxia and cerebral dysfunction. The similarity between the symptoms accompanying this syndrome and those seen during a classic migraine attack has led many investigators to suggest a common underlying pathophysiology. The purpose of this report is to highlight the salient clinical features and diagnostic approaches to this syndrome, thereby providing ophthalmologists and emergency room physicians a heightened awareness of this entity and the means to detect it.
