    Abdominal pain is among the most frequent ailments reported in the office setting and can account for up to 40% of ailments in the ambulatory practice. Also, it is in the top three symptoms of patients presenting to emergency departments (ED) and accounts for 5-10% of all ED primary presenting ailments. There are several common sources for acute abdominal pain and many for subacute and chronic abdominal pain. This article explores the history-taking, initial evaluation, and examination of the patient presenting with acute abdominal pain. The goal of this article is to help differentiate one source of pain from another. Discussion of acute cholecystitis, pancreatitis, appendicitis, ectopic pregnancy, diverticulitis, gastritis, and gastroenteritis are undertaken. Additionally, there is discussion of common laboratory studies, diagnostic studies, and treatment of the patient with the above entities.

    Acute abdominal pain is a common clinical condition. Clinical signs and symptoms can be difficult to interpret, and diagnostic imaging may help to identify intra-abdominal disease. Conventional X-ray, ultrasound (US) and computed tomography (CT) of the abdomen vary in usability between common surgical causes of acute abdominal pain. Overall, conventional X-ray cannot confidently diagnose or rule out disease. US and CT are equally trustworthy for most diseases. US with subsequent CT may enhance diagnostic precision. Magnetic resonance seems promising for future use in acute abdominal imaging.

  3. Can C-reactive protein and white blood cell count alone rule out an urgent condition in acute abdominal pain?

    PubMed

    2016-02-01

    Up to 10% of all patients at the Emergency Department present for acute abdominal pain. The C-reactive protein (CRP) and white blood cell (WBC) are routinely determined as part of the workup of patients with abdominal pain. Three large prospective cohort studies comprising a total of 2961 adult patients with acute abdominal pain were selected. CRP levels and WBC counts were compared between patients with urgent and nonurgent final diagnoses. These studies conclude that the laboratory values individually are weak discriminators and cannot be used as a triage instrument in the selection of patients with acute abdominal pain requiring additional diagnostic tests.

    External abdominal hernia occurs when abdominal organs or tissues leave their normal anatomic site and protrude outside the skin through the congenital or acquired weakness, defects or holes on the abdominal wall, including inguinal hernia, umbilical hernia, femoral hernia and so on. Acute incarcerated hernia is a common surgical emergency. With advances in minimally invasive devices and techniques, the diagnosis and treatment have witnessed major changes, such as the use of laparoscopic surgery in some cases to achieve minimally invasive treatment. However, strict adherence to the indications and contraindications is still required. PMID:25489584

  5. Omental infarction and its mimics: imaging features of acute abdominal conditions presenting with fat stranding greater than the degree of bowel wall thickening.

    The segmental omental infarction is a rare self-limited disorder presenting with aspecific clinical symptoms that may mimic several acute abdominal conditions. Therefore, a correct noninvasive diagnosis is important because treatment approaches range from monitoring to surgery. As omental infarction results in an important fat stranding that is much greater than the degree of bowel wall thickening, it suggests a narrower differential diagnosis: appendicitis, diverticulitis, epiploic appendagitis, and mesenteric panniculitis. In this pictorial essay, we point out the importance of imaging in identifying this typical sign allowing alternate diagnoses such as segmental omental infarction that can be conservatively managed.

    Despite of significant development of modern surgery results of treatment of acute diffused peritonitis and acute intestinal obstruction are still unsatisfactory. Successful treatment of these conditions depends considerably on timely and adequate diagnosing as it gives a choice of optimal treatment tactics. Measuring of a human body heat flow in areas of organs affected by pathology in cases of acute diffused peritonitis and acute intestinal obstruction provides a possibility to improve the principles of early differential diagnosing, to form new approaches to treatment tactics and monitoring of general health status of a patient during early postoperative treatment. 47 patient suffering from acute diffused peritonitis and 42 patients suffering from acute intestinal obstruction have been examined; the patients were divided into groups based on abdominal cavity exudates character, intestinal obstruction type and intra-abdominal hypertension grade. Measurement of abdominal cavity heat flow was performed by a contact method with use of thermoelectric medical thermometer. Intra-abdominal hypertension was measured by generally used transvesical method. It has been established that abdominal cavity heat flow correlates with character of abdominal cavity exudates; this is also confirmed by reliable difference between serous peritonitis and fibrinopurulent peritonitis indices. Indices in case of acute intestinal obstruction are lower than ones in case of acute diffused peritonitis as there are no inflammatory changes of peritoneum. Development of intra-abdominal hypertension of grades 3-4 directly influences the heat flow extent; this is explained by accelerated and aggravated pathological changes of inner organs cased by the main disease. Thus, abdominal cavity heat flow fully reflects degree of purulent and inflammatory processes of abdominal cavity organs and can be used for additional diagnosing and clinical course monitoring.

    Abstract Introduction: Abdominal compartment syndrome (ACS) after endovascular repair (EVAR) of rupture abdominal aortic aneurysm (rAAA) is a rare emergency situation, which has a high mortality. However, the progression of ACS is rapid and the diagnosis is usually been delayed, which increase the difficulties in treatment and affect the prognosis. We describe a case of a sever complication (acute intestinal necrosis) resulting from ACS after endovascular repair of rAAA. Clinical Finding: An elderly man, 81 years old, complained a sudden lower abdominal and back pain without any predisposing cause. He had a history of hypertension for 20 years without any regular anti-hypertensive therapy. Physical Examination revealed that the blood pressure was 89/54 mmHg, pulse was 120/min, oxygen saturation was 91%. The abdominal ultrasound and the CTA (computed tomography angiography) scan revealed a rAAA. Emergency EVAR under general anesthesia was performed for this patient. Diagnosis: Fourteen hours after endovascular repair, sudden decreased of blood pressure (70/50 mmHg) and oxygen saturation (70%) was observed. ACS or bleeding of retroperitoneal space was diagnosed. Interventions: Abdominal laparotomy was immediately performed. ACS was verified and a severe complication (acute intestinal necrosis) was observed, intestinal resection was performed for this patient. Outcomes: Unfortunately, this patient died after operation because of multi-organ failure in a very short period, which is very rare regarding to this condition. Surgical pathology, diagnosis and management were discussed. Conclusion: ACS was occurred with a severe complication (acute intestinal necrosis) in a very short period, which is very rare regarding to this condition after EVAR, it reminds us the severe result of ACS and more methods to prevent it happened after surgical management.

    Acute intermittent porphyria (AIP) is a rare condition characterized by abdominal pain and a wide range of nonspecific symptoms. We report the case of a woman with abdominal pain and syndrome of inappropriate antidiuretic hormone secretion (SIADH) as clinical presentation of AIP. The diagnosis was achieved through the etiologic study of the SIADH.

    Intracardiac masses are detected more frequently due to the availability of echocardiography. Right atrial thrombosis is rare comparatively with that of the left atrium. The clinical presentation of the patient with right atrial thrombosis is linked with a misleading association between cardiovascular signs and digestive signs (acute abdominal pain, vomiting and marmorated skin of flanks). Initial clinical suspicions of acute pancreatitis, entero-mesenteric infarction and complicated gastro-duodenal ulcer were invalidated by imagistic investigations -- echocardiography and CT. The massive thrombus located in the right atrium, prolapsing during diastole through the tricuspid valve, was associated with the increase in plasmatic D-dimers and new ECG modifications type right bundle block (hemodynamic straining of the right ventricle). The evolution was favorable, after heparin-therapy by infusing pump, with relief of cardiovascular and digestive symptoms after the first 6 hours; after 36 h from the beginning of the treatment the thrombus was lysed. Sudden death likelihood through complete obstruction of the tricuspid ostium was prevented due to the early diagnosis offered by imagistic methods.

    Acute abdominal pain is a common presentation in the outpatient setting and can represent conditions ranging from benign to life-threatening. If the patient history, physical examination, and laboratory testing do not identify an underlying cause of pain and if serious pathology remains a clinical concern, diagnostic imaging is indicated. The American College of Radiology has developed clinical guidelines, the Appropriateness Criteria, based on the location of abdominal pain to help physicians choose the most appropriate imaging study. Ultrasonography is the initial imaging test of choice for patients presenting with right upper quadrant pain. Computed tomography (CT) is recommended for evaluating right or left lower quadrant pain. Conventional radiography has limited diagnostic value in the assessment of most patients with abdominal pain. The widespread use of CT raises concerns about patient exposure to ionizing radiation. Strategies to reduce exposure are currently being studied, such as using ultrasonography as an initial study for suspected appendicitis before obtaining CT and using low-dose CT rather than standard-dose CT. Magnetic resonance imaging is another emerging technique for the evaluation of abdominal pain that avoids ionizing radiation.

    Introduction: Tuberculosis is an important cause of morbidity in India. Abdominal Tuberculosis is a great mimicker and is difficult to diagnose. This prospective observational study is based on those patients who were diagnosed to be suffering from Abdominal Tuberculosis only after they presented with an acute abdomen. This study aims to document the nature of different types of acute presentation in Abdominal Tuberculosis according to involved sites and surgical pathology. The study also discusses the indications and extent of surgical intervention. Materials and Methods: Seventy new cases of Abdominal Tuberculosis (out of 718 cases of acute abdomen) were diagnosed and treated over a period of three years in the surgical ward of Calcutta National Medical College. Macroscopic appearance of abdominal tissues during surgery suggested the diagnosis of tuberculosis. The diagnosis was confirmed by histopathology and tissue culture. All patients were subsequently treated with a full course of antitubercular drugs (ATD). Results: The clinical presentations of acute abdomen included acute intestinal obstruction, perforative peritonitis and acute appendicitis etc. Terminal ileum and ileocaecal region were predominantly involved. The most common pathology was intestinal stricture with or without perforation. Most of the patients (approx 78.5%) required emergency surgery as a therapeutic intervention. A two-stage procedure was preferred in peritonitis and sepsis. Most of the remaining patients (12.8%) required surgery after initial conservative treatment for the first few days. Undiagnosed Abdominal Tuberculosis represents a notable percentage (10%) of patients who present with an acute abdomen as a surgical emergency. Conclusion: Abdominal Tuberculosis is very difficult to diagnose and diagnosis is often delayed till an acute abdomen is presented with. Almost all patients needed surgical intervention. Irrespective of surgery, all patients of abdominal tuberculosis require a

    Dengue fever is an acute febrile viral disease caused by the bite of Aedes aegypti mosquito. It is a major health problem especially in tropical and subtropical areas including South East Asia and Pakistan. In the past few years, dengue fever has been endemic in Northern Punjab. Physicians managing dengue fever come across varied and uncommon complications of dengue fever. We report a case of dengue fever that developed severe right upper quadrant abdominal pain and induration after extreme retching and vomiting for 2 days. A rectus sheath hematoma was confirmed on noncontrast computed tomography (CT). Rectus sheath hematoma as a complication of dengue fever has rarely been reported before and never from this part of the world. Rectus sheath hematoma is an uncommon and often clinically misdiagnosed cause of abdominal pain. It is the result of bleeding into the rectus sheath from damage to the superior or inferior epigastric artery or their branches or from a direct tear of the rectus muscle. It can mimic almost any abdominal condition (See Fig.) (See Table).

    Although uncommon, lead poisoning should be considered as a differential diagnosis in cases of unexplained acute abdominal pain in both adults and children. We present the case of a 35-year-old Asian male who presented with abdominal pain and constipation secondary to lead poisoning. Initially, the source of lead exposure was not apparent; this was later found to be due to ingestion of an Ayurvedic herbal medicine for the treatment of infertility. Lead poisoning due to the ingestion of Ayurvedic remedies is well described. We discuss the diagnosis, pathophysiology and treatment of lead poisoning. This case illustrates one of the rarer medical causes of acute abdominal pain and emphasizes the need to take a thorough history (including specific questioning regarding the use of over-the-counter and traditional/ herbal remedies) in cases of suspected poisoning or drug toxicity.

    Appendicitis in the neonatal period is extremely rare. Its low incidence together with non-specific clinical symptoms often mean the diagnosis is delayed, leading to increased rates of peritonitis and mortality. We report the case of a 33-week premature infant, small for gestational age (1180 g at birth), clinically stable and receiving exclusive enteral feeding, who presented clinical manifestations of necrotizing enterocolitis at 14 days of life. Acute phase reactants were elevated and abdominal radiography showed pneumoperitoneum. Laparotomy revealed acute perforated appendicitis without intestinal involvement and purulent fluid in the peritoneum, for which appendectomy was performed. Neonatal acute appendicitis should be considered in the differential diagnosis of abdominal sepsis since early diagnosis and treatment significantly reduce associated morbidity and mortality.

    In this paper we analyze the results of diagnosis and treatment of 130 patients with acute surgical diseases of the abdominal cavity, complicated by peritonitis. We proposed the method of estimating the severity of the patients using a coefficient of status severity (C(SS)), developed a scale for prediction of complicated outcomes of acute surgical pathology of the abdominal cavity and abdominal sepsis, which is adapted to the working conditions of local clinics. Using the C(SS) and the scale prediction, allowed timely identification of patients' risk group with possible complicated course, assign adequate treatment, reduce postoperative complications by 5%, relaparotomies by 4.4%, decrease postoperative mortality by 3.9%.

    OBJECTIVE: Analysis of a staged management scheme for initial and definitive management of acute abdominal wall defects is provided. METHODS: A four-staged scheme for managing acute abdominal wall defects consists of the following stages: stage I--prosthetic insertion; stage II--2 to 3 weeks after prosthetic insertion and wound granulation, the prosthesis is removed; stage III--2 to 3 days later, planned ventral hernia (split thickness skin graft [STSG] or full-thickness skin and subcutaneous fat); stage IV--6 to 12 months later, definitive reconstruction. Cases were evaluated retrospectively for benefits and risks of the techniques employed. RESULTS: Eighty-eight cases (39 visceral edema, 27 abdominal sepsis, 22 abdominal wall resection) were managed during 8.5 years. Prostheses included polypropylene mesh in 45 cases, polyglactin 910 mesh in 27, polytetrafluorethylene in 10, and plastic in 6. Twenty-four patients died from their initial disease. The fistula rates associated with prosthetic management was 9%; no wound-related mortality occurred. Most wounds had split thickness skin graft applied after prosthetic removal. Definitive reconstruction was undertaken in 21 patients in the authors' institution (prosthetic mesh in 12 and modified components separation in 9). Recurrent hernias developed in 33% of mesh reconstructions and 11% of the components separation technique. CONCLUSIONS: The authors concluded that 1) this staged approach was associated with low morbidity and no technique-related mortality; 2) prostheses placed for edema were removed with fascial approximation accomplished in half of those cases; 3) absorbable mesh provided the advantages of reasonable durability, ease of removal, and relatively low cost--it has become the prosthesis of choice; and 4) the modified components separation technique of reconstruction provided good results in patients with moderate sized defects.

    Ultrasonography was performed as the first imaging procedure in 100 patients who presented with acute right upper quadrant pain suggestive of cholecystitis or cholelithiasis. In the final analysis 46 patients were found to have gallbladder disease (40 patients with cholelithiasis, 5 with acalculous cholecystitis, and 1 with a cholesterol polyp in the gallbladder). In 22 of 54 patients with a normal gallbladder, other abdominal disease was found. The error rate for ultrasound was 5%, and in 4 patients ultrasound was not the suitable procedure for the diagnosis. In 91 patients the ultrasonographic diagnosis was correct.

    A non-sequential Bayesian analysis was deemed a suitable approach to the important clinical problem of analysis of acute abdominal pain in the Emergency Room. Using series reported in the literature as a data source complemented by expert clinical estimates of probabilities of clinical data a program has been established in St. Boniface, Canada. Prior to implementing the program as an online, quickly available diagnostic aid, a prospective preliminary study has shown that the performance of computer plus clinician is significantly better than either clinician or computer alone. A major emphasis has been developing the acceptability of the program in real-life diagnoses in the Emergency Room.

    Acute thrombotic or embolic occlusion of the abdominal aorta is a rare vascular emergency associated with high morbidity and mortality rates. Classically, the clinical presentation is a severe peripheral ischemia with bilateral leg pain as the predominant feature. Aortic occlusion presenting as an isolated acute onset of paraplegia due to spinal cord ischemia is very rare and requires improved awareness to prevent adverse outcomes associated with delayed diagnosis. We report the case of a 54-year-old man who presented with sudden paraplegia due to the thrombotic occlusion of the infrarenal aorta involving the first segment of the common iliac arteries on both sides; emergent transperitoneal aorto iliac thrombectomy combined with the endovascular iliac kissing-stent technique were performed achieving perioperative complete regression of the symptoms.

    "Acute abdomen" includes spectrum of medical and surgical conditions ranging from a less severe to life-threatening conditions in a patient presenting with severe abdominal pain that develops over a period of hours. Accurate and rapid diagnosis of these conditions helps in reducing related complications. Clinical assessment is often difficult due to availability of over-the-counter analgesics, leading to less specific physical findings. The key clinical decision is to determine whether surgical intervention is required. Laboratory and conventional radiographic findings are often non-specific. Thus, cross-sectional imaging plays a pivotal role for helping direct management of acute abdomen. Computed tomography is the primary imaging modality used for these cases due to fast image acquisition, although US is more specific for conditions such as acute cholecystitis. Magnetic resonance imaging or ultrasound is very helpful in patients who are particularly sensitive to radiation exposure, such as pregnant women and pediatric patients. In addition, MRI is an excellent problem-solving modality in certain conditions such as assessment for choledocholithiasis in patients with right upper quadrant pain. In this review, we discuss a multimodality approach for the usual causes of non-traumatic acute abdomen including acute appendicitis, diverticulitis, cholecystitis, and small bowel obstruction. A brief review of other relatively less frequent but important causes of acute abdomen, such as perforated viscus and bowel ischemia, is also included.

    Acute alcohol intoxication is a common cause of emergency visits worldwide. Although moderate alcohol consumption is protective against coronary artery disease, binge drinking is associated with adverse cardiovascular and neurological outcomes and may even cause sudden death. Although, few past accounts of venous thrombosis with alcohol binge drinking are available, arterial thrombosis with the condition has never been reported in the literature. We present the unusual case of a young Afghan male, who presented to us with painful, tender and swollen legs three days after a heavy alcohol binge on a Saturday night. He was diagnosed as a case of acute limb ischemia secondary to massive abdominal aorta and bilateral femoral artery thrombosis. He also had acute renal failure secondary to rhabdomyolysis. Cardiac workup revealed new onset paroxysmal atrial fibrillation and a large thrombus in the left ventricular cavity. His blood ethanol level was high. He was treated by a multidisciplinary team; urgent surgical thrombectomy for thrombotic complications, intravenous fluid hydration and later renal replacement therapy for acute renal failure. To the best of our knowledge, such a constellation of clinical features in association with severe acute alcohol intoxication has not been reported in the literature. We believe, the procoagulant nature of high blood ethanol levels and the onset of atrial fibrillation after the heavy alcohol binge, known as the holiday heart syndrome, precipitated the thrombotic events leading to rhabdomyolysis and acute renal failure. Through this case, we conclude that a very heavy alcohol binge may cause thrombotic occlusion of the abdominal aorta and femoral arteries resulting in ischemic rhabdomyolysis and acute renal failure. A high index of suspicion must be kept, especially for a patient presenting with tender, swollen lower limbs and acute renal failure after an alcohol binge. PMID:28083449

    Lipocalin proteins are small regulatory peptides implicated in metabolism, inflammation, and immunity. Although lipocalin proteins have been linked to various clinical conditions, their role in the acute inflammatory setting, such as acute pancreatitis (AP), has only been sparsely investigated. Two members of the lipocalin family, lipocalin-2 (LCN-2) and retinol binding protein -4 (RBP-4), play an important role in obesity and insulin resistance. In this study, we analysed circulating levels of LCN-2 and RBP-4 in 92 individuals after AP, of whom 41 individuals had abdominal obesity and 51 did not. Binary logistic regression analyses were performed to determine whether abdominal obesity was associated with the two lipocalin proteins. Lipocalin-2 was significantly associated with abdominal obesity in the unadjusted model (Odds ratio (OR)=1.014 [95% confidence interval (CI): 1.000, 1.028], P=0.05) and after adjusting for patient related (age, ethnicity, and diabetes mellitus) and pancreatitis related (aetiology, severity, recurrence, and duration of AP) characteristics (OR=1.018 [95% CI: 1.001, 1.036], p=0.04). Further, the association of LCN-2 with waist circumference was significant in individuals with alcohol aetiology of AP (β=1.082 [95% CI: 1.011, 1.158], p=0.02]. The association between RBP-4 and abdominal obesity was not significant in both unadjusted and adjusted models. These findings indicate that circulating levels of LCN-2 in patients after AP may play a role in chronic low grade inflammation associated with abdominal adiposity and that alcohol consumption may further exacerbate adipose tissue dysfunction.

    The accurate diagnosis of pediatric acute abdominal pain is one of the most challenging tasks in the emergency department (ED) due to its unclear clinical presentation and non-specific findings in physical examinations, laboratory data, and plain radiographs. The objective of this study was to evaluate the impact of abdominal multidetector computed tomography (MDCT) performed in the ED on pediatric patients presenting with acute abdominal pain. A retrospective chart review of children aged <18 years with acute abdominal pain who visited the emergency department and underwent MDCT between September 2004 and June 2007 was conducted. Patients with a history of trauma were excluded. A total of 156 patients with acute abdominal pain (85 males and 71 females, age 1-17 years; mean age 10.9 ± 4.6 years) who underwent abdominal MDCT in the pediatric ED during this 3-year period were enrolled in the study. One hundred and eighteen patients with suspected appendicitis underwent abdominal MDCT. Sixty four (54.2%) of them had appendicitis, which was proven by histopathology. The sensitivity of abdominal MDCT for appendicitis was found to be 98.5% and the specificity was 84.9%. In this study, the other two common causes of nontraumatic abdominal emergencies were gastrointestinal tract (GI) infections and ovarian cysts. The most common etiology of abdominal pain in children that requires imaging with abdominal MDCT is appendicitis. MDCT has become a preferred and invaluable imaging modality in evaluating uncertain cases of pediatric acute abdominal pain in ED, in particular for suspected appendicitis, neoplasms, and gastrointestinal abnormalities.

    The use of diagnostic laparoscopy in acute abdominal pain, especially when patients have been admitted for acute pain in the lower abdominal quadrants, improves the accuracy of diagnosis and leads to improvements in treatment procedures. A case is reported of a 24-year-old woman admitted under suspicion of appendicitis. The appendix was found to be normal, and a perforation caused by a fishbone was discovered in a Meckel's diverticulum. The diverticulum was resected by a combined laparoscopic and open procedure. Diagnostic laparoscopy should be performed routinely in cases of acute abdominal pain in the lower quadrants of suspected appendiceal origin to avoid overlooking other causes of the symptoms.

    Acute abdomen is one of the most common clinical conditions requiring a radiological investigation. Ultrasound is the primary modality of choice which can diagnose some of the common causes of acute abdomen. However, sometimes the underlying cause for the pain is far more complicated than expected mandating a high degree of suspicion to suggest further investigation with contrast enhanced computed tomography or magnetic resonance imaging. Here, we have compiled a comprehensive series of selected cases to highlight the conditions which can be easily overlooked unless carefully sought for. This article also emphasizes the importance of multimodality approach to arrive at the final diagnosis with an increased overall diagnostic accuracy which in turn improves patient management and prognosis.

    General surgeons are often asked to evaluate acute abdominal pain which has an expanded differential diagnosis in women of childbearing age. Acute appendicitis accounts for many surgical emergencies as a common cause of nongynecologic pelvic pain. In some rare instances, acute appendicitis has been shown to occur simultaneously with a variety of gynecologic diseases. We report a case of concurrent acute appendicitis and ruptured ovarian endometrioma. PMID:28097032

    Introducción: la presión intraabdominal es el estado de equilibrio de la presión de la cavidad abdominal en reposo y puede presentar cambios durante la ventilación mecánica o espontánea. El objetivo fue determinar la presión intraabdominal como predictor de cirugía en el paciente con dolor abdominal agudo. Métodos: se llevó a cabo un estudio de casos y controles anidado en una cohorte de pacientes con dolor abdominal agudo en el servicio de urgencias de un hospital de segundo nivel, en el periodo comprendido entre abril y diciembre de 2013. Se incluyeron 37 pacientes, todos fueron intervenidos quirúrgicamente con previa toma de la presión intraabdominal. Se formaron los grupos con el resultado del estudio anatomopatológico: con evidencia de proceso inflamatorio abdominal agudo (n = 28) y sin evidencia de proceso inflamatorio abdominal agudo (n = 9). Resultados: en los casos el 100 % presentó presión intraabdominal alta con una p = 0.01, RM: 5 (IC 95 %: 2.578-9.699). En los casos la media de la presión intraabdominal fue de 11.46 y en los controles de 9.2 (p = 0.183). Conclusiones: el dolor abdominal que requiere cirugía para su resolución tiene relación directa con una presión intraabdominal > 5 mmHg.

    The efficacy and merit of testicular imaging, utilizing Tc-99m pertechnetate, were studied prospectively in a group of patients who presented with acute onset of scrotal pain. Consecutive admissions were studied. All were managed according to the likelihood of the problem being testicular torsion, which was determined from the clinical history, physical examination and the routine laboratory data. The final diagnostic outcome, whether by surgical exploration or clinical progress with conservative treatment, is collated with the preoperative scintigraphic interpretations, made with respect to predefined criteria. Analysis of the pretreatment images obtained in 57 patients shows that the radionuclide study is highly reliable in cases of testicular torsion and epididymo-orchitis. It appears to be much less dependable, however, in the other acute scrotal conditions. Torsions that are intermittent in nature or corrected manually apparently can have variable presentations. Certain difficulties and potential pitfalls encountered in interpreting the scintigraphic studies are discussed.

    Background: Acute abdominal pain is a common symptom of emergency patients. The severity was always evaluated based on physicians’ clinical experience. The aim of this study was to establish an early risk stratification method (ERSM) for addressing adults with acute abdominal pain, which would guide physicians to take appropriate and timely measures following the established health-care policies. Methods: In Cohort 1, the records of 490 patients with acute abdominal pain that developed within the past 72 h were enrolled in this study. Measurement data and numeration data were compared with analysis of variance and Chi-square test, respectively. Multiple regression analysis calculated odd ratio (OR) value. P and OR values showed the impacts of factors. ERSM was established by clinical experts and statistical experts according to Youden index. In Cohort 2, data from 305 patients with acute abdominal pain were enrolled to validate the accuracy of the ERSM. Then, ERSM was prospectively used in clinical practice. Results: The ERSM was established based on the scores of the patient's clinical characteristics: right lower abdominal pain + 3 × diffuse abdominal pain + 3 × cutting abdominal pain + 3 × pain frequency + 3 × pain duration + fever + 2 × vomiting + 5 × stop defecation + 3 × history of abdominal surgery + hypertension history + diabetes history + hyperlipidemia history + pulse + 2 × skin yellowing + 2 × sclera yellowing + 2 × double lung rale + 10 × unconsciousness + 2 × right lower abdominal tenderness + 5 × diffuse abdominal tenderness + 4 × peritoneal irritation + 4 × bowel sounds abnormal + 10 × suspicious diagnosis + white blood cell count + hematocrit + glucose + 2 × blood urea nitrogen + 3 × creatine + 4 × serum albumin + alanine aminotransferase + total bilirubin + 3 × conjugated bilirubin + amylase. When the score was <18, the patient did not need hospitalization. A score of ≥18 and <38 indicated that the patient should be under

    AIM: To study the effect of combined indwelling catheter, hemofiltration, respiration support and traditional Chinese medicine (e.g. Dahuang) in treating abdominal compartment syndrome of fulminant acute pancreatitis. METHODS: Patients with fulminant acute pancreatitis were divided randomly into 2 groups of combined indwelling catheter celiac drainage and intra-abdominal pressure monitoring and routine conservative measures group (group 1) and control group (group 2). Routine non-operative conservative treatments including hemofiltration, respiration support, gastrointestinal TCM ablution were also applied in control group patients. Effectiveness of the two groups was observed, and APACHE II scores were applied for analysis. RESULTS: On the second and fifth days after treatment, APACHE II scores of group 1 and 2 patients were significantly different. Comparison of effectiveness (abdominalgia and burbulence relief time, hospitalization time) between groups 1 and 2 showed significant difference, as well as incidence rates of cysts formation. Mortality rates of groups 1 and 2 were 10.0% and 20.7%, respectively. For patients in group 1, celiac drainage quantity and intra-abdominal pressure, and hospitalization time were positively correlated (r = 0.552, 0.748, 0.923, P < 0.01) with APACHE II scores. CONCLUSION: Combined indwelling catheter celiac drainage and intra-abdominal pressure monitoring, short veno-venous hemofiltration (SVVH), gastrointestinal TCM ablution, respiration support have preventive and treatment effects on abdominal compartment syndrome of fulminant acute pancreatitis.

    Fat stranding adjacent to thickened bowel wall seen at computed tomography (CT) in patients with acute abdominal pain suggests an acute process of the gastrointestinal tract, but the differential diagnosis is wide. The authors observed "disproportionate" fat stranding (ie, stranding more severe than expected for the degree of bowel wall thickening present) and explored how this finding suggests a narrower differential diagnosis, one that is centered in the mesentery: diverticulitis, epiploic appendagitis, omental infarction, and appendicitis. The characteristic CT findings (in addition to fat stranding) of each of these entities often lead to a final diagnosis. Diverticulitis manifests with mild, smooth bowel wall thickening and no lymphadenopathy. Epiploic appendagitis manifests with central areas of high attenuation and a hyperattenuated rim, in addition to its characteristic location adjacent to the colon. In contrast, omental infarction is always centered in the omentum. The most specific finding of appendicitis is a dilated, fluid-filled appendix. Correct noninvasive diagnosis is important because treatment approaches for these conditions range from monitoring to surgery.

    Surgery on the reason of the "acute abdomen" in children often reveals the persisting vaginal peritoneal defects, which further lead to hernia formation. 23 children (aged 4-15 years) were operated on the acute uncomplicated appendicitis (n=10), acute mesadenitis (n=3), appendicular local and pelvioperitonitis (n=9) and ovary apoplexia (n=1). Inguinal hernia was revealed in all patients during laparoscopy. After videoendoscopic sanation of the abdomen and appendectomy (if it was necessary) the extraperitoneal ligation herniorraphy in author's modification was performed. The were no cases of abdominal complications as well as hernia recurrence among the treated patients.

    Cytomegalovirus infections are widely distributed with a seroprevalence of up to 100%. The majority of the cases take a silent course or deal with unspecific clinical symptoms. Complications in immunocompetent patients are rare but may affect the liver and lead up to an acute organ failure. In this case report, we describe a 35-year-old immunocompetent female with an acute cytomegalovirus infection presenting as acute hepatitis with ongoing upper right abdominal pain after cholecystectomy. Upper right abdominal pain is a common symptom with a wide range of differential diagnoses. If common reasons can be excluded, we want to sensitize for cytomegalovirus infection as a minor differential diagnosis even in immunocompetent patients. PMID:27403100

    Background. Acute intestinal obstruction during pregnancy is a very challenging and unusual nonobstetric surgical entity often linked with considerable fetomaternal morbidity and mortality. When it is synchronous with abdominal pregnancy, it is even rarer. Case Presentation. A 28-year-old lady in her second pregnancy was referred to Nnamdi Azikiwe University Teaching Hospital, Nnewi, Nigeria, at 27 weeks of gestation due to vomiting, constipation, and abdominal pain. Examination and ultrasound scan revealed a single live intra-abdominal extrauterine fetus. Plain abdominal X-ray was diagnostic of intestinal obstruction. Conservative treatment was successful till the 34-week gestational age when she had exploratory laparotomy. At surgery, the amniotic sac was intact and the placenta was found to be adherent to the gut. There was also a live female baby with birth weight of 2.3 kg and Apgar scores of 9 and 10 in the 1st and 5th minutes, respectively, with the baby having right clubbed foot. Adhesiolysis and right adnexectomy were done. The mother and her baby were well and were discharged home nine days postoperatively. Conclusion. To the best of our knowledge, this is the first report of abdominal pregnancy as the cause of acute intestinal obstruction in the published literature. Management approach is multidisciplinary.

    2013-02-01

    Abdominal compartment syndrome is an under-recognized cause of acute kidney injury in critically ill patients. We report a case of a patient with severe obstructive lung disease who, while intubated for respiratory failure, developed abdominal compartment syndrome and oliguric acute kidney injury due to air-trapping and excessive auto-positive end-expiratory pressure (auto-PEEP; also known as intrinsic PEEP). When chemical paralysis was initiated and the auto-PEEP resolved, the patient's intra-abdominal hypertension rapidly improved and kidney function recovered immediately. Abdominal compartment syndrome secondary to excessive auto-PEEP appears to be unreported in the literature; however, any process that significantly increases intrathoracic pressure conceivably could cause increased pressure to be transmitted to the abdominal compartment, resulting in organ failure. Patients undergoing mechanical ventilation, which puts them at risk of airflow obstruction and the development of intra-abdominal hypertension, should be evaluated for air-trapping and excessive auto-PEEP.

    2015-12-01

    The susceptibility of the undescended testis to malignant transformation is well documented. The most common location of the undescended testis is within the inguinal canal, with only a minority located within the abdominal cavity. When a testicular mass develops, the risk of torsion increases. We describe a large intra-abdominal testicular seminoma that had undergone torsion, rupture and haemorrhage, presenting as an acute abdomen. A 30 year old man presented to the emergency department with right iliac fossa pain. Computed tomography in the emergency department showed haemoperitoneum and a torted large left testicular mass, likely malignant. The patient underwent laparotomy and excision of the mass. Histologic examination revealed a grossly enlarged seminomatous testis which had torted and ruptured. While pre-operative imaging diagnosis of an intra-abdominal testicular seminoma has been published, reports are few. To the best of the author's knowledge pre-operative imaging diagnosis of a malignant testicular mass with torsion and intra-abdominal haemorrhage presenting as an acute abdomen has not been described before.

    Adipocytokines are strongly associated with abdominal adiposity during the course of acute pancreatitis (AP). This study investigated associations between a panel of adipocytokines and abdominal adiposity in AP patients after hospital discharge, as well as the effect of several covariates. Fasting venous blood samples were collected to measure adiponectin, interleukin 6, leptin, monocyte chemoattractant protein 1, tumour necrosis factor α (TNFα), resistin, and retinol-binding protein 4. Waist circumference (WC), waist-hip ratio, and waist-height ratio (WheightR) were used as measures of abdominal adiposity. Generalised linear models were built, adjusting for age, sex, ethnicity, diabetes status, aetiology, duration since admission for AP, recurrence, and severity of AP. A total of 93 patients were studied, on average at 22 months after AP. Interleukin 6, TNFα, and leptin were significantly associated with WC in both the unadjusted and all the three adjusted models. Also, they were significantly associated with WheightR in both the unadjusted and the three adjusted models. Other studied adipocytokines did not show a consistent association or were not significantly associated with the abdominal adiposity indices. The results suggest that excess abdominal adiposity favours pro-inflammatory milieu in AP patients after hospital discharge, independent of diabetes and effect of other covariates.

    Endovascular aortic repair (EVAR) was relatively safe, and became a widely performed procedure. If aortic dissection (AD) occurred in patient with previous EVAR, it could cause fatal complications like endograft collapse. Surgical treatment was limited in this situation for comorbidities and complex anatomies.

    Kaempferol (KF) is the most abundant polyphenol in tea, fruits, vegetables, and beans. However, little is known about its in vivo anti-inflammatory efficacy and mechanisms of action. To study these, several acute mouse inflammatory and nociceptive models, including gastritis, pancreatitis, and abdominal pain were employed. Kaempferol was shown to attenuate the expansion of inflammatory lesions seen in ethanol (EtOH)/HCl- and aspirin-induced gastritis, LPS/caerulein (CA) triggered pancreatitis, and acetic acid-induced writhing.

    Abdominal varices consisting of a caput medusae and dilated mesenteric veins resulted in pooling of Tc-99m tagged red blood cells (RBC) within these dilated vessels in a 57-year-old man with severe Laennec's cirrhosis. The atypical radiotracer localization within the abdomen mimicked an acute gastrointestinal hemorrhage. Clinical suspicion and careful evaluation of scintigraphic gastrointestinal bleeding studies will avoid false-positive interpretations.

    Objectives Intra-abdominal fungal infections (AFI) complicating acute pancreatitis arise in the context of pancreatic necrosis. Our goal was to determine which risk factors contribute to AFI in patients with acute pancreatitis. Methods Records were reviewed from 479 non-transfer patients admitted to our medical center with acute pancreatitis from 1985–2009. Using multivariable regression models, risk factors for AFI were identified. Results Out of 479 patients admitted with acute pancreatitis, 17 patients were subsequently found to have an AFI and 3 of these patients expired. The mean length of stay for patients with an AFI was 24 days and 76% were admitted to the intensive care unit. Patients with AFI were more likely to have received prophylactic antibiotics on admission (OR 1.7, 95% C.I. 1.2–2.3), TPN within 7 days of admission (OR 1.4, 95% C.I. 1.1–1.7) or to have necrosis on CT scan within 7 days of admission (OR 1.4, 95% C.I. 1.1–1.7). Multivariable regression models identified admission antibiotic use (OR 1.6, 95% C.I. 1.4–1.8) as the strongest predictor of AFI. Conclusion Admission antibiotics are the biggest risk factor for the development of intra-abdominal fungal infections in acute pancreatitis. Prophylactic antibiotics to prevent infected necrosis should therefore be discouraged. PMID:25872170

    Acute gastric dilation is a rare but recognised complication in patients with bulimia and anorexia following binge episodes owing to decreased bowel motility. We present a rare case of acute gastric dilation secondary to bulimia in an otherwise healthy 18-year-old female patient that resulted in compression and complete occlusion of the abdominal aorta, leading to acute mesenteric and bilateral lower limb ischaemia. This resolved immediately following a laparotomy and gastric decompression. Management of these patients is very challenging owing to the lack of a successful precedent. To our knowledge, such a catastrophic complication has only ever been reported once in the literature and the outcome was fatal. Our case is of additional importance as it offers a successful management strategy for these patients.

The course of disease, however, may be complicated by multiorgan dysfunction such as in Weil's disease. We present a case of Weil's disease with pancreatitis in a young Caucasian man residing in Hawai‘i. Although leptospirosis is common in Hawai‘i, few patients present with pancreatitis. This report of leptospirosis-induced pancreatitis should help raise awareness of clinicians to assess for pancreatitis when evaluating a patient with leptospirosis and acute abdominal pain.

    Background Tears of the abdominal obliques have previously been reported in the vicinity of the lower ribs but they have not been reported in the vicinity of the iliac crest. The purpose of this case report is to describe the mechanism of injury and diagnosis of a distal abdominal oblique tear and subsequent rehabilitation programming. Case Description A 21-year-old male Australian football player experienced acute right-sided abdominal pain during a game while performing a commonly executed rotation skill. He was assessed clinically before being further examined with ultrasound and magnetic resonance imaging which revealed a rupture of the abdominal oblique wall at its insertion onto the iliac crest. The player then underwent a structured and graduated rehabilitation program with clear key performance indicators to optimize return to play and prevent recurrence. Outcomes The player was able to return to play at 35 days post injury and had no recurrence or complications at 12 month follow up post injury. Discussion This is the first time an abdominal oblique wall rupture at its insertion onto the iliac crest has been reported. In players with acute abdominal pain following twisting an insertional oblique tear should be considered as a differential diagnosis. A structured rehabilitation program may also help optimize an athlete's return to play after distal abdominal oblique rupture. PMID:27999726

    Introduction Acute appendicitis in children is a clinical diagnosis, which often requires preoperative confirmation with either ultrasound (US) or computed tomography (CT) studies. CTs expose children to radiation, which may increase the lifetime risk of developing malignancy. US in the pediatric population with appropriate clinical follow up and serial exam may be an effective diagnostic modality for many children without incurring the risk of radiation. The objective of the study was to compare the rate of appendiceal rupture and negative appendectomies between children with and without abdominal CTs; and to evaluate the same outcomes for children with and without USs to determine if there were any associations between imaging modalities and outcomes. Methods We conducted a retrospective chart review including emergency department (ED) and inpatient records from 1/1/2009–2/31/2010 and included patients with suspected acute appendicitis. Results 1,493 children, aged less than one year to 20 years, were identified in the ED with suspected appendicitis. These patients presented with abdominal pain who had either a surgical consult or an abdominal imaging study to evaluate for appendicitis, or were transferred from an outside hospital or primary care physician office with the stated suspicion of acute appendicitis. Of these patients, 739 were sent home following evaluation in the ED and did not return within the subsequent two weeks and were therefore presumed not to have appendicitis. A total of 754 were admitted and form the study population, of which 20% received a CT, 53% US, and 8% received both. Of these 57%, 95% CI [53.5,60.5] had pathology-proven appendicitis. Appendicitis rates were similar for children with a CT (57%, 95% CI [49.6,64.4]) compared to those without (57%, 95% CI [52.9,61.0]). Children with perforation were similar between those with a CT (18%, 95% CI [12.3,23.7]) and those without (13%, 95% CI [10.3,15.7]). The proportion of children with a

    Caustic ingestion is a common cause of life-threatening upper gastrointestinal tract injuries. It mostly happens in children as accidental exposure, but may occur in adults as a result of suicide attempt. We present a case of an acute abdomen that occurred after a peculiar way of self-administration of sulfuric acid as a suicide attempt in an adult psychiatric male patient, already known for self-harm with caustic agents in the previous years. In a few hours, the patient developed diffuse peritonitis, pneumoperitoneum, and a rapid hemodynamic deterioration, as a consequence of ileum and sigmoid necrosis, requiring an emergency surgery with the application of a damage control strategy. The patient was then transferred to intensive care unit for hemodynamic stabilization, and definitive surgical correction of the abdominal lesions was performed after 3 days with Hartmann procedure. Thirty-nine days after hospital admission, the patient was discharged. In conclusion, to our knowledge, never has been reported in the literature a case of intra-abdominal self-administration of caustic substance causing a rapid evolution of clinical conditions and requiring the application of damage control strategy.

    2015-01-01

    Background Severe impairment of the major respiratory muscles resulting from tetraplegia reduces respiratory function, causing many people with tetraplegia to require mechanical ventilation during the acute stage of injury. Abdominal Functional Electrical Stimulation (AFES) can improve respiratory function in non-ventilated patients with sub-acute and chronic tetraplegia. The aim of this study was to investigate the clinical feasibility of using an AFES training program to improve respiratory function and assist ventilator weaning in acute tetraplegia. Methods AFES was applied for between 20 and 40 minutes per day, five times per week on four alternate weeks, with 10 acute ventilator dependent tetraplegic participants. Each participant was matched retrospectively with a ventilator dependent tetraplegic control, based on injury level, age and sex. Tidal Volume (VT) and Vital Capacity (VC) were measured weekly, with weaning progress compared to the controls. Results Compliance to training sessions was 96.7%. Stimulated VT was significantly greater than unstimulated VT. VT and VC increased throughout the study, with mean VC increasing significantly (VT: 6.2 mL/kg to 7.8 mL/kg VC: 12.6 mL/kg to 18.7 mL/kg). Intervention participants weaned from mechanical ventilation on average 11 (sd: ± 23) days faster than their matched controls. Conclusion The results of this study indicate that AFES is a clinically feasible technique for acute ventilator dependent tetraplegic patients and that this intervention may improve respiratory function and enable faster weaning from mechanical ventilation.

    An 82-year-old woman without any previous medical history arrived in the emergency department with severe pain in the entire abdomen since 5 h. Blood tests showed, apart from a CRP of 28 mg/l, no abnormalities. We decided to perform an abdominal ultrasound, which showed an easily compressible gallbladder, containing a small, mobile gallstone and free fluid in the abdomen. During ultrasound-guided punction of this fluid, bile is aspirated. We performed laparoscopy and confirmed a large amount of intraperitoneal bile. Upon inspecting the gallbladder a perforation is seen in the anti-hepatic side of the gallbladder. After performing a cholecystectomy, we opened the gallbladder and detected a dissection-like lesion, which provided access to the peritoneal cavity. The confirmed diagnosis was acute onset free perforation of the gallbladder. The perforation was probably caused by the small obstructing gallstone seen on ultrasound or by another small stone, which could not be visualized.

    Introduction Abdominal compartment syndrome (ACS) and intra abdominal hypertension(IAH) are common clinical findings in patients with severe acute pancreatitis(SAP). It is thought that an increased intra abdominal pressure(IAP) is associated with poor prognosis in SAP patients. But the detailed effect of IAH/ACS on different organ system is not clear. The aim of this study was to assess the effect of SAP combined with IAH on hemodynamics, systemic oxygenation, and organ damage in a 12 h lasting porcine model. Measurements and Methods Following baseline registrations, a total of 30 animals were divided into 5 groups (6 animals in each group): SAP+IAP30 group, SAP+IAP20 group, SAP group, IAP30 group(sham-operated but without SAP) and sham-operated group. We used a N2 pneumoperitoneum to induce different levels of IAH and retrograde intra-ductal infusion of sodium taurocholate to induce SAP. The investigation period was 12 h. Hemodynamic parameters (CO, HR, MAP, CVP), urine output, oxygenation parameters(e.g., SvO2, PO2, PaCO2), peak inspiratory pressure, as well as serum parameters (e.g., ALT, amylase, lactate, creatinine) were recorded. Histological examination of liver, intestine, pancreas, and lung was performed. Main Results Cardiac output significantly decreased in the SAP+IAH animals compared with other groups. Furthermore, AST, creatinine, SUN and lactate showed similar increasing tendency paralleled with profoundly decrease in SvO2. The histopathological analyses also revealed higher grade injury of liver, intestine, pancreas and lung in the SAP+IAH groups. However, few differences were found between the two SAP+IAH groups with different levels of IAP. Conclusions Our newly developed porcine SAP+IAH model demonstrated that there were remarkable effects on global hemodynamics, oxygenation and organ function in response to sustained IAH of 12 h combined with SAP. Moreover, our model should be helpful to study the mechanisms of IAH/ACS-induced exacerbation and

    Initial examination and therapy, and the avoidance of maltreatment are emphasized. Gastric decompression is of prime importance, after which no compound should be administered via stomach tube. Where large amounts of high starch grains are fed, primary acute gastric dilatation must be differentiated from that secondary to small bowel dilatation, by immediate gastric intubation and irrigation of the cardia with lidocaine. If cessation of pain and improvement of peristalsis and general attitude follow, the former state may be assumed. If pain persists and peristalsis does not improve markedly, one should assume small bowel displacement. Rectal examination is helpful in initial evaluation: impactions, inguinal herniation and ileocaecal intussusception may be diagnosed and small bowel displacement suspected. Palpation of one or more distended loops of bowel in the ventral middle third of the abdomen indicates small bowel displacement or ileus and flaccid distension. Distinction by rectal palpation alone is difficult. Palpation of the gas-distended apex of the caecum in the middle third of the abdomen is virtually pathognomonic for 180 degrees rotation of the large bowel. Abdominal paracentesis yielding true sanguineous effusion indicates a necrotizing segment of the bowel. If negative, such a segment is absent, or there is an infarcted segment, not yet damaged to the point of leaching whole blood, or the necrotizing segment is outside the peritoneal cavity, i.e., in the thorax, intussuscepted into the caecum, or herniated into the inguinal canal. Recurrent colics frequently may be due to verminous arteritis but the relationship to diet should be investigated. Recurrent colics after grain ingestion with occult blood in the faeces may be due to ulcers; such cases respond well to grain withdrawal. The advantages and disadvantages of phenothiazine-derived tranquillizers are discussed. They are contra-indicated if there is any evidence of circulating volume insufficiency

In 26 patients the diagnosis was confirmed, basing on serologic analysis data. The presence of intraabdominal catastrophe, caused by abdominal tuberculosis complications on inactive pulmonary tuberculosis background witnesses with 85.3% probability the HIV-infectioning of the patient.

    Intra-abdominal hypertension (IAH) is a common and serious complication in critically ill patients for which there is no well-defined treatment strategy. Here, we explored the effect of IAH on multiple intestinal barriers and discussed whether the alteration in microflora provides clues to guide the rational therapeutic treatment of intestinal barriers during IAH. Using a rat model, we analysed the expression of tight junction proteins (TJs), mucins, chemotactic factors, and Toll-like receptor 4 (TLR4) by immunohistochemistry. We also analysed the microflora populations using 16S rRNA sequencing. We found that, in addition to enhanced permeability, acute IAH (20 mmHg for 90 min) resulted in significant disturbances to mucosal barriers. Dysbiosis of the intestinal microbiota was also induced, as represented by decreased Firmicutes (relative abundance), increased Proteobacteria and migration of Bacteroidetes from the colon to the jejunum. At the genus level, Lactobacillus species and Peptostreptococcaceae incertae sedis were decreased, whereas levels of lactococci remained unchanged. Our findings outline the characteristics of IAH-induced barrier changes, indicating that intestinal barriers might be treated to alleviate IAH, and the microflora may be an especially relevant target.

    The objectives of this study were to document the utilization of MRI compared with CT in pregnant patients presenting with acute nontraumatic abdominal pain at our institution and to compare the diagnostic performance of the two modalities. A retrospective review identified all pregnant patients at our institution who had MRI or CT exams of the abdomen and/or pelvis for acute nontraumatic abdominal pain over a 3-year period from January 2008 through December 2010. The imaging diagnoses were compared with pathologic data or operative findings as the primary reference standard or with clinical follow-up and laboratory data as the secondary reference standard. Patients without surgically proven diagnoses were followed clinically until delivery, when possible. Ninety-four pregnant patients were included in this study: 61 MRI exams were performed in 57 patients, 44 CT exams were performed in 43 patients (including six patients who had both), and 72 patients (77 %) had ultrasound prior to cross-sectional imaging, with the appendix specifically assessed in 25 patients but visualized in only two of them. Of 61 MRI exams, 24 were considered positive for imaging diagnoses, 33 were negative, and 4 were equivocal. Of 44 CT exams, 24 were positive and 20 were negative. The test characteristics for MRI and CT in the diagnosis of acute abdominal pain were as follows: sensitivity 91 and 88 %, specificity 85 and 90 %, positive predictive value 81 and 91 %, negative predictive value 94 and 8 5 %, and diagnostic accuracy 88 and 88 %, respectively. Differences were not statistically significant (p value = 1). The majority of MRIs (34/61 = 56 %) were read by emergency radiologists. MRI and CT performed equally well in the evaluation of acute nontraumatic abdominal pain during pregnancy. Given its lack of ionizing radiation, MRI may be preferable. Given that the majority of MRIs were read by radiologists specializing in emergency imaging, this is a technique that emergency

    A 112-amino-acid protein irisin (IRI) is widely expressed in many organs, but we currently do not know whether appendix tissue and blood cells express it. If appendix tissue and neutrophil cells express IRI, measuring its concentration in biological fluids might be helpful in the diagnosis of acute appendicitis (AA), since neutrophil cells are the currently gold-standard laboratory parameters for the diagnosis of AA. Therefore, the purpose of this study was to investigate the suitability of enzyme-linked immunosorbent assay-based measurements of the proposed myokine IRI for the discrimination of patients with AA from those with acute abdominal pain (AP) and healthy controls. Moreover, immunoreactivity to IRI was investigated in appendix tissues and blood cells. Samples were collected on admission (T1), 24 hours (T2), and 72 hours (T3) postoperatively from patients with suspected AA and from patients with AP corresponding to T1–T3, whereas control subject blood was once corresponding to T1. IRI was measured in serum, saliva, and urine by using enzyme-linked immunosorbent assay, whereas in appendix tissue and blood cells, IRI was detected by immunohistohcemistry. Appendix tissue and blood cells (except for erythrocytes) are new sources of IRI. Basal saliva, urine, and serum levels were higher in children with AA compared with postoperative levels (T2) that start to decline after surgery. This is in line with the finding that IRI levels are higher in children with AA when compared with those with AP or control subject levels, most likely due to a large infiltration of neutrophil cells in AA that release its IRI into body fluids. Measurement of IRI in children with AA parallels the increase or decrease in the neutrophil count. This new finding shows that the measurement of IRI and neutrophil count can together improve the diagnosis of AA, and it can distinguish it from AP. IRI can be a candidate marker for the diagnosis of AA and offers an additional parameter to

    Background Acute abdominal pain (AAP) accounts for 7–10% of all Emergency Department (ED) visits. Nevertheless, the epidemiology of AAP in the ED is scarcely known. The aim of this study was to investigate the epidemiology and the outcomes of AAP in an adult population admitted to an urban ED. Methods We made a retrospective analysis of all records of ED visits for AAP during the year 2014. All the patients with repeated ED admissions for AAP within 5 and 30 days were scrutinized. Five thousand three hundred and forty cases of AAP were analyzed. Results The mean age was 49 years. The most frequent causes were nonspecific abdominal pain (NSAP) (31.46%), and renal colic (31.18%). Biliary colic/cholecystitis, and diverticulitis were more prevalent in patients aged >65 years (13.17% vs. 5.95%, and 7.28% vs. 2.47%, respectively). Appendicitis (i.e., 4.54% vs. 1.47%) and renal colic (34.48% vs. 20.84%) were more frequent in patients aged <65 years. NSAP was the most common cause in both age classes. Renal colic was the most frequent cause of ED admission in men, whereas NSAP was more prevalent in women. Urinary tract infection was higher in women. Overall, 885 patients (16.57%) were hospitalized. Four hundred and eighty-five patients had repeated ED visits throughout the study period. Among these, 302 patients (6.46%) were readmitted within 30 days, whereas 187 patients (3.82%) were readmitted within 5 days. Renal colic was the first cause for ED readmission, followed by NSAP. In 13 cases readmitted to the ED within 5 days, and in 16 cases readmitted between 5–30 days the diagnosis was changed. Conclusions Our study showed that AAP represented 5.76% of total ED visits. Two conditions (i.e., NSAP and renal colic) represented >60% of all causes. A large use of active clinical observations during ED stay (52% of our patients) lead to a negligible percentage of changing diagnosis at the second visit. PMID:27826565

    Complete congenital absence of the omentum is very rare with only one previously reported case. We present a unique case of the management of a pregnant woman with a large pelvic pseudocyst caused by complications related to congenital absence of omentum, resulting in acute kidney injury, likely secondary to acute compartment syndrome. This case highlights the importance of considering acute compartment syndrome in critically unwell pregnant women and reiterates the need to measure intra-abdominal pressure when clinically indicated. Given that pregnancy is in itself a state of intra-abdominal hypertension, obstetricians should maintain a high index of suspicion in the context of additional risk factors.

    A 16-y-old girl presented with abdominal pain in the lower right quadrant, ranging in intensity from 2 to 10 on a visual analog scale (VAS) that prevented her from attending school. The pain was not associated with reflux, a fever, or blood in her stools. Eosinophilic esophagitis (EE) had been previously diagnosed, but treatment with a proton pump inhibitor (PPI) was not successful. The patient's medical history was significant for allergies to fruit; trees, including birch; weeds; and pollen. She had also suffered an anaphylactic reaction to a raw apple. The treatment approach commonly used for EE is suppression of inflammation with steroid therapy with short-term removal of offending foods. However, an attempt to reduce allergic bias and inflammation and treat intestinal permeability is not a part of the standard approach and may explain the high rate of relapse with the condition. Treatment included an elimination diet paired with a supplement regimen designed to reduce inflammation, support healing of the gut and reduce type 2 helper T (Th2) bias of her allergic response. As a result of treatment, the patient's severe pain episodes abated and she was thereafter able to resume attendance at school.

    We present a case of acute postoperative abdominal pain after proctosigmoidectomy and colorectal anastomosis that was treated by bilateral continuous quadratus lumborum block. The block was performed in the lateral position under ultrasound guidance with a 15-mL bolus of 0.5% bupivacaine injected anterior to the quadratus lumborum muscle followed by bilateral catheter placement. Each catheter received a continuous infusion of 0.1% bupivacaine at 8 mL/h and an on-demand bolus 5 mL every 30 minutes. Sensory level was confirmed by insensitivity to cold from T7 through T12. The block was devoid of hemodynamic side effects or motor weakness. This case demonstrates that bilateral continuous quadratus lumborum catheters can provide extended postoperative pain control.

    Aim: The aim of this study was to investigate a relationship between seasonal variation and incidence of type A acute aortic dissection (AAD) and spontaneous abdominal aneurysm rupture (rAAA) in Canton Tuzla, Bosnia and Herzegovina. Patients and methods: A total of 81 cases, 41 AAD and 40 of ruptured AAA were identified from one center over a 6-year, from 2008 till 2013. In 2012 were admitted (45.6% or 36 patients). Results: Seasonal analysis showed that 19(23.4%) patients were admitted in spring, 15(18.5) in summer, 26(32%) in autumn and 21(25.9) in winter. The most frequent period was autumn/winter with 47 or 58% patients. A causal link between atmospheric pressure (AP) and incidence of rAAA and AAD on seasonal and monthly basis was found.

    Background Current abdominal aortic aneurysm (AAA) screening in men age 65 might have limited impact on overall AAA death rates if incidence is moving to older ages. Up-to-date population-based studies of age-specific incidence, risk factors, and outcome of acute AAA are needed to inform screening policy. Methods and Results In a prospective, population-based study (Oxfordshire, UK, 2002–2014), the incidence and outcome of acute AAA events were determined. Based on population projections and current incidence trends, the impact of screening strategies in the UK was estimated. Over the 12-year period, 103 incident acute AAA events occurred in the study population of 92 728. Incidence/100 000/year was 55 in men ages 65 to 74 years, but increased to 112 at 75 to 85 and 298 at ≥85, with 66.0% of all events occurring at age ≥75 years. Incidence at ages 65 to 74 was highest in male smokers (274), with 96.4% of events in men <75 years occurring in ever-smokers. Extrapolating rates to the UK population, using trial evidence of screening efficacy, the current UK screening program would prevent 5.6% of aneurysm-related deaths (315 200 scans/year: 1426/death prevented, 121/year-of-life saved). Screening only male smokers age 65 and then all men at age 75 would prevent 21.1% of deaths (247 900 scans/year; 297/death prevented, 34/year-of-life saved). By 2030, 91.0% of deaths will occur at age ≥75, 61.6% at ≥85, and 28.6% in women. Conclusions Given that two thirds of acute AAA occurred at ≥75 years of age, screening older age groups should be considered. Screening nonsmokers at age 65 is likely to have very little impact on AAA event rates. PMID:26289347

    To assess the diagnostic value of ultrasound compared to CT in evaluating acute abdominal pain of different causes in children 10 years of age and under, hospital records and imaging files of 4052 patients under age of 10 who had imaging for abdominal pain were reviewed. One-hundred-thirty-two patients (3 %), (74 males/58 females) who underwent ultrasound and CT within 24 h were divided by age: group I, ages 0-48 months (25 patients); group II, 49-84 months (53 patients); and group III, 85-120 months (54 patients). Diagnoses at ultrasound, CT, and discharge were compared. Cases of a change in diagnosis following CT and impact of the changed diagnosis on patient management were assessed. Non-diagnostic ultrasound or a diagnostic conundrum was present in a small percentage (3 %) of our patients. In the group of patients imaged with two modalities, CT changed the diagnosis in 73/132 patients (55.3 %). Patient management changed in 63/132 patients (47.7 %). CT changed the diagnosis in 46/64 patients with surgical conditions (71.8 %, p < 0.001). Among patients with surgical conditions, the difference between ultrasonography (US) and CT diagnoses was significant in groups 2 (p = 0.046) and 3 (p =  .001). The impact of the change in diagnosis in surgical patients imaged with two modalities was significant in the group as a whole and in each age group separately. Non-diagnostic or equivocal US in a small percentage of patients is probably sufficient to justify the additional radiation burden.

    Abdominal bleeding is a lethal complication in acute pancreatitis (AP) and it is commonly described as a late event. However, spontaneous intra-abdominal bleeding could occur very early but no study focusing on this phenomenon was published yet. In this study, 1137 AP patients were retrospectively screened and 24 subjects suffering early spontaneous bleeding (ESB) were selected. Meanwhile, a 1:1 well-balanced cohort of non-bleeding patients was generated by propensity score match. The clinical characteristics of these patients were compared and a multiple regression analysis was performed to assess the risk factors for ESB. Besides, patients with massive post-intervention bleeding (PIB) were collected for additional comparison. ESB patients suffered significantly worse outcome than the matched cohort evidenced by dramatically higher mortality than the non-bleeding patients and even the PIB group (54.2% versus 20.8%, P = 0.017; 54.2% versus 31.0%, P = 0.049). The regression analysis demonstrated computer tomography severity index (CTSI; OR, 3.34; 95% CI, 1.995–5.59, P < 0.001) and creatinine (OR, 1.008; 95% CI, 1.004–1.012, P < 0.001) were associated with the occurrence of ESB. In conclusion, ESB is a rare but dangerous complication of moderate-to-severe AP and may result in high mortality. CTSI and creatinine are independent risk factors for the development of ESB.

    Background Acute kidney injury (AKI) is frequent during hospitalization and may contribute to adverse consequences. We aimed to evaluate long-term adverse renal function and mortality after postoperative AKI in a cohort of patients undergoing major abdominal surgery. Methods We performed a retrospective analysis of adult patients who underwent major non-vascular abdominal surgery between January 2010 and February 2011 at the Department of Surgery II of Hospital de Santa Maria–Centro Hospitalar Lisboa Norte, Portugal. Exclusion criteria were as follows: chronic kidney disease on renal replacement therapy, undergoing renal replacement therapy the week before surgery, death before discharge and loss to follow-up through January 2014. Patients were categorized according to the development of postoperative AKI in the first 48 h after surgery using the Kidney Disease: Improving Global Outcomes classification. AKI was defined by an increase in absolute serum creatinine (SCr) ≥0.3 mg/dL or by a percentage increase in SCr ≥50% and/or by a decrease in urine output to <0.5 mL/kg/h for >6 h. Adverse renal outcomes (need for long-term dialysis and/or a 25% decrease in estimated glomerular filtration rate after hospital discharge) and mortality after discharge were evaluated. Cumulative mortality was analysed with the Kaplan–Meier method and log-rank test and outcome predictive factors with the Cox regression. Significance was set at P < 0.05. Results Of 390 selected patients, 72 (18.5%) developed postoperative AKI. The median follow-up was 38 months. Adverse renal outcomes and death after hospital discharge were more frequent among AKI patients (47.2 versus 22.0%, P < 0.0001; and 47.2 versus 20.5%, P < 0.0001, respectively). The 4 year cumulative probability of death was 44.4% for AKI patients, while it was 19.8% for patients with no AKI (log-rank test, P < 0.0001). In multivariate analysis, AKI was a risk factor for adverse renal outcomes (adjusted hazard ratio 1.6, P

    Neutrophils form neutrophil extracellular traps (NETs) of decondensed DNA and histones that trap and immobilize particulate matter and microbial pathogens like bacteria. NET aggregates reportedly surround and isolate large objects like monosodium urate crystals, which cannot be sufficiently cleared from tissues. In the setting of acute necrotizing pancreatitis, massive tissue necrosis occurs, which is organized as pancreatic pseudocysts (1). In contrast to regular cysts, these pseudocysts are not surrounded by epithelial layers. We hypothesize that, instead, the necrotic areas observed in necrotizing pancreatitis are isolated from the surrounding healthy tissues by aggregated NETs. These may form an alternative, putatively transient barrier, separating necrotic areas from viable tissue. To test this hypothesis, we investigated histological samples from the necropsy material of internal organs of two patients with necrotizing pancreatitis and peritonitis accompanied by multiple organ failure. Tissues including the inflammatory zone were stained with hematoxylin and eosin and evaluated for signs of inflammation. Infiltrating neutrophils and NETs were detected by immunohistochemistry for DNA, neutrophil elastase (NE), and citrullinated histone H3. Interestingly, in severely affected areas of pancreatic necrosis or peritonitis, chromatin stained positive for NE and citrullinated histone H3, and may, therefore, be considered NET-derived. These NET structures formed a layer, which separated the necrotic core from the areas of viable tissue remains. A condensed layer of aggregated NETs, thus, spatially shields and isolates the site of necrosis, thereby limiting the spread of necrosis-associated proinflammatory mediators. We propose that necrotic debris may initiate and/or facilitate the formation of the NET-based surrogate barrier. PMID:27777576

    Acute intensive care (IC) triage involves a challenging decision-making process. Physicians are required to make life or death decisions about an unfamiliar patient within a short time frame. An 84-year-old female was admitted to the stroke unit following an extensive cerebral infarction. The intensive care unit (ICU) physician was consulted because of a suspected severe abdominal sepsis even though ICU treatment had never previously been discussed. A 77-year-old female with a previous history of myocardial infarction and severe COPD developed acute respiratory failure on the ward, and was admitted to the ICU for support by a mechanical ventilator. The family felt this was an inappropriate course of treatment, considering her former poor quality of life. When physicians are confronted with sudden deterioration of the patient's clinical condition without advanced care planning a limited-time IC treatment trial is often initiated, possibly leading to inappropriate ICU admissions. ICU treatment options should preferably be discussed beforehand; preliminary background information regarding the patient's wishes is essential for adequate decision-making.

    Epiploic appendagitis (EA) is an uncommon cause of abdominal pain. It is a benign condition but may mimic other serious causes of acute abdomen such as appendicitis, diverticulitis, and gynecological emergency in severe cases. Knowledge of this condition in the differential diagnosis of abdominal pain can save unnecessary hospital admission, antibiotics, and surgery. In this article, we present the case of a 43-year-old female who presented to our hospital with a 2-day history of right lower quadrant abdominal pain and diarrhea. She was diagnosed with EA with computed tomography of abdomen with contrast and was managed conservatively with good outcome. PMID:27987280

    During the immediate postoperative course after upper abdominal surgery, pulmonary complications often occur, caused, inter alia, by reduced regional ventilation and by atelectases as a result of: (1) narrowing of the small peripheral bronchi, and (2) impaired respiratory function. Based on these pathophysiological mechanisms, an instrument (Bartlett-Edwards Incentive Spirometer) has been devised, which aims at giving the patient an opportunity of sustained maximal inspiration under standardized and controlled conditions. The use of this instrument has been followed by reports of a considerable reduction in postoperative pulmonary complications. In a controlled clinical investigation of the pre- and postoperative condition of the lungs, we were unable to show any beneficial effect of the instrument. In general, we have a low frequency of severe postoperative pulmonary complications, as compared with the results reported in the literature. We ascribe this to our very effective pre- and postoperative respiratory therapy.

    Echinococcus multilocularis is an important pathogenic zoonotic parasite of health concern, though absent in the United Kingdom. Eurasian beavers (Castor fiber) may act as a rare intermediate host, and so unscreened wild caught individuals may pose a potential risk of introducing this parasite to disease-free countries through translocation programs. There is currently no single definitive ante-mortem diagnostic test in intermediate hosts. An effective non-lethal diagnostic, feasible under field condition would be helpful to minimise parasite establishment risk, where indiscriminate culling is to be avoided. This study screened live beavers (captive, n = 18 or wild-trapped in Scotland, n = 12) and beaver cadavers (wild Scotland, n = 4 or Bavaria, n = 11), for the presence of E. multilocularis. Ultrasonography in combination with minimally invasive surgical examination of the abdomen by laparoscopy was viable under field conditions for real-time evaluation in beavers. Laparoscopy alone does not allow the operator to visualize the parenchyma of organs such as the liver, or inside the lumen of the gastrointestinal tract, hence the advantage of its combination with abdominal ultrasonography. All live beavers and Scottish cadavers were largely unremarkable in their haematology and serum biochemistry with no values suspicious for liver pathology or potentially indicative of E. multilocularis infection. This correlated well with ultrasound, laparoscopy, and immunoblotting, which were unremarkable in these individuals. Two wild Bavarian individuals were suspected E. multilocularis positive at post-mortem, through the presence of hepatic cysts. Sensitivity and specificity of a combination of laparoscopy and abdominal ultrasonography in the detection of parasitic liver cyst lesions was 100% in the subset of cadavers (95%Confidence Intervals 34.24-100%, and 86.7-100% respectively).

  12. Targeted endothelial nanomedicine for common acute pathological conditions.

    Endothelium, a thin monolayer of specialized cells lining the lumen of blood vessels is the key regulatory interface between blood and tissues. Endothelial abnormalities are implicated in many diseases, including common acute conditions with high morbidity and mortality lacking therapy, in part because drugs and drug carriers have no natural endothelial affinity. Precise endothelial drug delivery may improve management of these conditions. Using ligands of molecules exposed to the bloodstream on the endothelial surface enables design of diverse targeted endothelial nanomedicine agents. Target molecules and binding epitopes must be accessible to drug carriers, carriers must be free of harmful effects, and targeting should provide desirable sub-cellular addressing of the drug cargo. The roster of current candidate target molecules for endothelial nanomedicine includes peptidases and other enzymes, cell adhesion molecules and integrins, localized in different domains of the endothelial plasmalemma and differentially distributed throughout the vasculature. Endowing carriers with an affinity to specific endothelial epitopes enables an unprecedented level of precision of control of drug delivery: binding to selected endothelial cell phenotypes, cellular addressing and duration of therapeutic effects. Features of nanocarrier design such as choice of epitope and ligand control delivery and effect of targeted endothelial nanomedicine agents. Pathological factors modulate endothelial targeting and uptake of nanocarriers. Selection of optimal binding sites and design features of nanocarriers are key controllable factors that can be iteratively engineered based on their performance from in vitro to pre-clinical in vivo experimental models. Targeted endothelial nanomedicine agents provide antioxidant, anti-inflammatory and other therapeutic effects unattainable by non-targeted counterparts in animal models of common acute severe human disease conditions.

    Investigation of indices of lactate dehydrogenase (LDG) and creatine phosphokinase (CPK) in a group of patients with extensive necrotic alterations in organs of the abdominal cavity and in a group of patients without extensive necroses has shown that in the first group there were higher levels of LDG and CPK. It shows that the LDG and CPK indices may be used as markers of tissue necrosis of the abdominal organs. In addition, in patients who died against the background of growing polyorganic insufficiency the LDG and CPK level by the end of treatment was statistically reliably higher than on admission of the same patients that may be an indicator of growing phenomena of dystrophy and micronecroses in vitals, so the indices of LDG and CPK may show the degree of severity of polyorganic insufficiency and determine its prognosis.

    Severe water deficit (SD) severely limited the photo-assimilate supply during the grain-filling stages. Although the ethylene and polyamines (PAs) have been identified as important signaling molecules involved in stress tolerance, it is yet unclear how 1-Aminocylopropane-1-carboxylic acid (ACC) and PA biosynthesis involving wheat abdominal phloem characters mitigate SD-induced filling inhibition. The results obtained indicated that the SD down-regulated the TaSUT1 expression and decreased the activities of sucrose synthase (SuSase, EC2.4.1.13), ADP glucose pyrophosphorylase (AGPase, EC2.7.7.27), soluble starch synthase (SSSase, EC2.4.1.21), then substantially limited grain filling. As a result, increased ACC and putrescine (Put) concentrations and their biosynthesis-related gene expression reduced spermidine (Spd) biosynthesis under SD condition. And, the ACC and PA biosynthesis in inferior grains was more sensitive to SD than that in superior grains. Intermediary cells (ICs) of caryopsis emerged prematurely under SD to compensate for the weakened photo-assimilate transport functions of sieve elements (SEs). Finally, plasmolysis and nuclear chromatin condensation of phloem parenchyma cells (PPC) and membrane degradation of SEs, as well as the decreased ATPase activity on plasma membranes of ICs and PPC at the later filling stage under SD were responsible for the considerably decreased weight of inferior grains.

    Hereditary angioedema (HAE) is a potentially fatal genetic disorder typified by a deficiency (type I) or dysfunction (type II) of the C1-inhibitor (C1-INH) and characterized by swelling of the extremities, face, trunk, abdominal viscera, and upper airway. Type III is normal estrogen-sensitive C1-INH HAE. Bradykinin, the main mediator of HAE, binds to endothelial B2 receptors, increasing vascular permeability and resulting in edema. HAE management includes short- and long-term prophylaxis. For treating acute episodes, C1-INH concentrate is recommended with regression of symptoms achieved in 30–90 min. Infusions of 500–1000 U have been used in Europe for years. Two plasma-derived C1-INH concentrates have been licensed recently in the United States: Berinert® for treating acute attacks and Cinryze® for prophylaxis in adolescent/adult patients. A recombinant C1-INH that is being considered for approval (conestat alfa) exhibited significant superiority versus placebo. Ecallantide (Kalbitor®) is a selective kallikrein inhibitor recently licensed in the United States for treating acute attacks in patients aged >16 years. It is administered in three 10-mg subcutaneous injections with the risk of anaphylactic reactions. Icatibant (Firazyr®) is a bradykinin B2 receptor competitor. It is administered subcutaneously as a 30-mg injection and approved in Europe but not in the United States. PMID:23776358

    Abdominal catastrophe is a serious clinical condition, usually being a complication arising during treatment of intraabdominal nontraumatic disorders or abdominal injuries. Most commonly, inflamation- secondary peritonitis, is concerned. Abdominal catastrophe also includes secondary signs of sepsis, abdominal compartment syndrome and enterocutaneous fistules. Most septic abdominal disorders which show signs of abdominal catastrophy, require surgical intervention and reinterventions--planned or "on demand" laparotomies. During the postoperative period, the patient requires intensive care management, including steps taken to stabilize his/hers condition, management of sepsis and metabolic and nutritional support measures, as well as adequate indication for reoperations. New technologies aimed at prevention of complications in laparostomies and to improve conditions for final laparotomy closure are used in phase procedures for surgical management of intraabdominal infections. Despite the new technologies, abdominal catastrophe has higher morbidity and lethality risk rates.

    Abdominal pregnancy is a rare entity, which has been classified as primary or secondary by Studiford criteria. A retrospective study, between January 1989 and December 1994, realized at Instituto Nacional de Perinatología, found 35,080 pregnancies, from which 149 happened to be ectopic, and 6 of them were abdominal. All patients belonged to a low income society class, age between 24 and 35 years, and average of gestations in 2.6. Gestational age varied from 15 weeks to 32.2 weeks having only one delivery at term with satisfactory postnatal evolution. One patient had a recurrent abdominal pregnancy, with genital Tb as a conditional factor. Time of hospitalization varied from 4 to 5 days, and no further patient complications were reported. Fetal loss was estimated in 83.4%. Abdominal pregnancy is often the sequence of a tubarian ectopic pregnancy an when present, it has a very high maternal mortality reported in world literature, not found in this study. The stated frequency of abdominal pregnancy is from 1 of each 3372, up to 1 in every 10,200 deliveries, reporting in the study 1 abdominal pregnancy in 5846 deliveries. The study had two characteristic entities one, the recurrence and two, the delivery at term of one newborn. Abdominal pregnancy accounts for 4% of all ectopic pregnancies. Clinical findings in abdominal pregnancies are pain, transvaginal bleeding and amenorrea, being the cardinal signs of ectopic pregnancy.

    New findings and diagnostic advances warrant revisiting key features of acute non-obstetric abdominal pain in pregnancy. Four of the most frequently seen conditions warranting surgical intervention are: appendicitis, cholecystitis, pancreatitis, and bowel obstruction. Because pregnancy often masks abdominal complaints, effectively assessing and triaging abdominal pain in pregnant women can be difficult. Working in obstetric triage settings and triaging obstetric phone calls demand continual updating of abdominal assessment knowledge and clinical skills.

    Sepsis is characterized by a severe systemic inflammatory response to infection that is associated with high morbidity and mortality despite optimal care. Invariant natural killer T (iNK T) cells are potent regulatory lymphocytes that can produce pro- and/or anti-inflammatory cytokines, thus shaping the course and nature of immune responses; however, little is known about their role in sepsis. We demonstrate here that patients with sepsis/severe sepsis have significantly elevated proportions of iNK T cells in their peripheral blood (as a percentage of their circulating T cells) compared to non-septic patients. We therefore investigated the role of iNK T cells in a mouse model of intra-abdominal sepsis (IAS). Our data show that iNK T cells are pathogenic in IAS, and that T helper type 2 (Th2) polarization of iNK T cells using the synthetic glycolipid OCH significantly reduces mortality from IAS. This reduction in mortality is associated with the systemic elevation of the anti-inflammatory cytokine interleukin (IL)-13 and reduction of several proinflammatory cytokines within the spleen, notably interleukin (IL)-17. Finally, we show that treatment of sepsis with OCH in mice is accompanied by significantly reduced apoptosis of splenic T and B lymphocytes and macrophages, but not natural killer cells. We propose that modulation of iNK T cell responses towards a Th2 phenotype may be an effective therapeutic strategy in early sepsis.

    In a patient with hypovolemic shock class 1, the vital signs and biochemical properties are almost normal. The alteration of hemodynamic parameters and biochemical values occurs mainly in advanced hypovolemia state (neuroendocrine response). The availability of ultrasound machine at healthcare centers makes the measurement of vascular calibre feasible and possible. Inspiration and expiration inferior vena cava diameter changes predict hypovolemic shock class 1 but in acute emergencies this method is impractical. The purpose of this study is to develop a new approach in identifying hypovolemic shock at early phase by measuring the inferior vena cava and aorta diameter ratio using bedside ultrasound machine.

    Background The effect of decompressive laparotomy on outcomes in patients with abdominal compartment syndrome has been poorly investigated. The aim of this prospective cohort study was to describe the effect of decompressive laparotomy for abdominal compartment syndrome on organ function and outcomes. Methods This was a prospective cohort study in adult patients who underwent decompressive laparotomy for abdominal compartment syndrome. The primary endpoints were 28‐day and 1‐year all‐cause mortality. Changes in intra‐abdominal pressure (IAP) and organ function, and laparotomy‐related morbidity were secondary endpoints. Results Thirty‐three patients were included in the study (20 men). Twenty‐seven patients were surgical admissions treated for abdominal conditions. The median (i.q.r.) Acute Physiology And Chronic Health Evaluation (APACHE) II score was 26 (20–32). Median IAP was 23 (21–27) mmHg before decompressive laparotomy, decreasing to 12 (9–15), 13 (8–17), 12 (9–15) and 12 (9–14) mmHg after 2, 6, 24 and 72 h. Decompressive laparotomy significantly improved oxygenation and urinary output. Survivors showed improvement in organ function scores, but non‐survivors did not. Fourteen complications related to the procedure developed in eight of the 33 patients. The abdomen could be closed primarily in 18 patients. The overall 28‐day mortality rate was 36 per cent (12 of 33), which increased to 55 per cent (18 patients) at 1 year. Non‐survivors were no different from survivors, except that they tended to be older and on mechanical ventilation. Conclusion Decompressive laparotomy reduced IAP and had an immediate effect on organ function. It should be considered in patients with abdominal compartment syndrome. PMID:26891380

The CT showed abnormal spleen 20 × 11 cm with free fluid in the abdomen and enlarged retroperitoneal LNs. The patient underwent a splenectomy after initial resuscitation and the operative finding was that of a massively enlarged spleen with areas of tumor extruding through the splenic capsule. Result and conclusion Although the spleen is often involved in hematological malignancies, splenic rupture is an infrequent occurrence. In a recent literature review 136 cases were of splenic rupture secondary to hematological malignancy were identified. Acute leukemia and non Hodgkin lymphoma were the frequent causes followed by chronic myelogeneous leukemia. Male sex, adulthood, severe splenomegaly and cytoreductive chemotherapy were factors more often associated with splenic rupture. Emergency splenectomy remains the cornerstone treatment for splenic rupture. We present a case report of a "spontaneous splenic rupture" and discuss the presentation, etiology and treatment options along with discussion of relevant literature PMID:17129392

    Abdominal emergencies during pregnancy (excluding obstetrical emergencies) occur in one out of 500-700 pregnancies and may involve gastrointestinal, gynecologic, urologic, vascular and traumatic etiologies; surgery is necessary in 0.2-2% of cases. Since these emergencies are relatively rare, patients should be referred to specialized centers where surgical, obstetrical and neonatal cares are available, particularly because surgical intervention increases the risk of premature labor. Clinical presentations may be atypical and misleading because of pregnancy-associated anatomical and physiologic alterations, which often result in diagnostic uncertainty and therapeutic delay with increased risks of maternal and infant morbidity. The most common abdominal emergencies are acute appendicitis (best treated by laparoscopic appendectomy), acute calculous cholecystitis (best treated by laparoscopic cholecystectomy from the first trimester through the early part of the third trimester) and intestinal obstruction (where medical treatment is the first-line approach, just as in the non-pregnant patient). Acute pancreatitis is rare, usually resulting from trans-ampullary passage of gallstones; it usually resolves with medical treatment but an elevated risk of recurrent episodes justifies laparoscopic cholecystectomy in the 2nd trimester and endoscopic sphincterotomy in the 3rd trimester. The aim of the present work is to review pregnancy-induced anatomical and physiological modifications, to describe the main abdominal emergencies during pregnancy, their specific features and their diagnostic and therapeutic management.

    Abdominal pain can result from a variety of different intra- and extra-abdominal disorders. Given the wide variety of etiological triggers for this pain, the primary task during the first stage of the diagnostic work-up is to determine as soon as possible the underlying cause and the degree of emergency. The aim of this evaluation is to adapt the therapeutic measures which are necessary for a causal treatment to the individual situation. Contrary to somatic causes of abdominal pain, the availability of such a causal therapy for functional bowel disorders is still very limited. Given this dilemma, the therapeutic focus of abdominal pain associated with these functional syndromes has to be placed on symptom-oriented treatment.

  13. Inflammatory abdominal aortic aneurysm.

    Between January 1976 and December 1982, 181 patients with abdominal aortic aneurysms were treated surgically, and in 13 patients the aneurysms were found to be inflammatory. Inflammatory aneurysms of the abdominal aorta (IAAA) share important characteristics with typical atherosclerotic abdominal aortic aneurysms. Diagnosis and surgical management of IAAA are distinctive which suggests that IAAA should be considered separately, as a varient of typical abdominal aortic aneurysms. IAAA occur predominantly in males. The presenting symptoms are often idiosyncratic and include severe abdominal or back pain, or both, and ureteral obstruction; the diagnosis of IAAA should be considered when these symptoms are present. Although grossly and microscopically, the perianeurysmal fibrosis resembles idiopathic retroperitoneal fibrosis, the two conditions can be differentiated. At the present time, ultrasonography and computed tomography appear to offer reliable means for diagnosing IAAA. The presence of IAAA, whether established preoperatively or discovered unexpectedly at operation, necessitate certain modifications in the surgical approach, in order to avoid injuring the duodenum and the venous structures. Most patients can be successfully treated by resection and graft replacement. Rupture of the aneurysm in IAAA appears to be less frequent than in typical atherosclerotic abdominal aortic aneurysm.

    Abdominal symptoms are among the most common reasons for pediatric emergency department visits, and abdominal pain is the most frequently reported symptom. Thorough history taking and physical examination can often reach the correct diagnosis. Knowing the abdominal conditions that are most common in each age group can help radiologists narrow the differential diagnosis. When imaging tests are indicated, ultrasonography is usually the first-line technique, enabling the diagnosis or adding relevant information with the well-known advantages of this technique. Nowadays, plain-film X-ray studies are reserved for cases in which perforation, bowel obstruction, or foreign body ingestion is suspected. It is also important to remember that abdominal pain can also occur secondary to basal pneumonia. CT is reserved for specific indications and in individual cases, for example, in patients with high clinical suspicion of abdominal disease and inconclusive findings at ultrasonography. We review some of the most common conditions in pediatric emergencies, the different imaging tests indicated in each case, and the imaging signs in each condition.

    Abdominal infections are an important challenge for the intensive care physician. In an era of increasing antimicrobial resistance, selecting the appropriate regimen is important and, with new drugs coming to the market, correct use is important more than ever before and abdominal infections are an excellent target for antimicrobial stewardship programs. Biomarkers may be helpful, but their exact role in managing abdominal infections remains incompletely understood. Source control also remains an ongoing conundrum, and evidence is increasing that its importance supersedes the impact of antibiotic therapy. New strategies such as open abdomen management may offer added benefit in severely ill patients, but more data are needed to identify its exact role. The role of fungi and the need for antifungal coverage, on the other hand, have been investigated extensively in recent years, but at this point, it remains unclear who requires empirical as well as directed therapy.

    Appropriate access to the abdominal cavity is the first and crucial step for successful abdominal surgical intervention. In planning the incision, several variables have to be considered, such as anatomy of the abdominal wall, localization of the target organ, and individual conditions (previous incisions, minimal access surgery, etc). Medial laparotomy is the preferred incision for emergency cases and ill-defined pathologies, allowing access and hence exploration to all quadrants. Transverse laparotomies give superior access to the dorsal and right aspects of the liver and cause less pain in patients unfit for regional anesthetic procedures. Draining of the abdominal cavity is used after various resective and reconstructive procedures, but there is little evidence for its use in a number of operations such as gastric, hepatic, and colorectal resections. Advantages and disadvantages of different abdominal wall incisions and drainages are discussed.

    90 patients with acute pancreatitis were observed, in 60 of them laparoscopic drainage was performed. The procedure by sterile pancreatonecrosis is indicated only in presence of extent amount of exudate in abdominal cavity. Duration of draining the abdominal cavity should be strictly limited because of the high risk of septic complications. Contraindications for the abdominal drainage by acute necrotic pancreatitis are not only adhesions in the abdomen and shock state of the patient at the moment of procedure necessity, but also unstable hemodynamics in anamnesis and even by the arterial pressure downtrend.

    Objectives Maintaining the constant exposure to hydrophobic organic compouds in acute toxicity tests is one of the most difficult issues in the evaluation of their toxicity and corresponding risks. Passive dosing is an emerging tool to keep constant aqueous concentration because of the overwhelming mass loaded in the dosing phase. The primary objectives of this study were to develop the constant exposure condition for an acute mortality test and to compare the performance of the passive dosing method with the conventional spiking with co-solvent. Methods A custom cut polydimethylsiloxane (PDMS) tubing loaded with benzyl butyl phthalate (BBP) was placed in each well of a 24-well plate containing assay medium. The rate of the release of BBP from PDMS was evaluated by measuring the change in the concentration of BBP in the assay medium. The efficiency of maintaining constant exposure condition was also evaluated using a simple two-compartment mass transport model employing a film-diffusion theory. An acute mortality test using 10 C. elegans in each well was conducted for the evaluation of the validity of passive dosing and the comparative evaluation of the passive dosing method and the conventional spiking method. Results Free concentration in the assay medium reached 95% steady state value within 2.2 hours without test organisms, indicating that this passive dosing method is useful for an acute toxicity test in 24 hours. The measured concentration after the mortality test agreed well with the estimated values from partitioning between PDMS and the assay medium. However, the difference between the nominal and the free concentration became larger as the spiked concentration approached water solubility, indicating the instability of the conventional spiking with a co-solvent. Conclusions The results in this study support that passive dosing provides a stable exposure condition for an acute toxicity test. Thus, it is likely that more reliable toxicity assessment can be

    Purpose/Background: Some physical therapists (PTs) provide services at sporting events, but there are limited studies investigating whether PTs are properly prepared to provide such services. The purpose of this study was to assess acute sports injury and medical condition management decision-making skills of PTs. Methods: A Web-based survey presented 17 case scenarios related to acute medical conditions and sport injuries. PTs from the Sports Physical Therapy Section of The American Physical Therapy Association were e-mailed a cover letter/Web link to the survey and invited to participate over a 30-day period. Data were analyzed using SPSS 18.0. Results: A total of 411 of 5158 PTs who were members of the Sports Physical Therapy Association in 2009 and had valid e-mail addresses completed the survey, of which 389 (7.5%) were appropriate for analysis. Over 75.0% of respondents felt “prepared” or “somewhat prepared” to provide immediate care for 13 out of 16 medical conditions, with seizures, spinal cord injuries, and internal organ injuries having the lowest percentages. Over 75.0% of the respondents made “appropriate” or “overly cautious” decisions for 11 of the 17 acute injury or medical condition cases. Conclusions: Results of the current study indicate that PTs felt more “prepared” and tended to make “appropriate” return to play decisions on the acute sports injury and medical condition case studies more often than coaches who participated in a similar study, regardless of level of importance of the game or whether the athlete was a starter vs. non-starter. However, for PTs who plan on assisting at sporting events, additional preparation/education may be recommended, such as what is taught in an emergency responder course. PMID:21904695

    Tuberculosis has staged a global comeback and forms a dangerous combination with AIDS. The abdomen is one of the common sites of extrapulmonary involvement. Patients with abdominal tuberculosis have a wide range and spectrum of symptoms and signs; the disease is therefore a great mimic. Diagnosis, mainly radiological and supported by endoscopy, is difficult to make and laparotomy is required in a large number of patient. Management involves judicious combination of antitubercular therapy and surgery which may be required to treat complications such as intestinal obstruction and perforation. The disease, though potentially curable, carries a significant morbidity and mortality.

We herein report a case of a previously undiagnosed AAA and a presenting complaint consistent with acute cholecystitis. Following cholecystectomy, this was noted to be a rare form of chronic cholecystitis: xanthogranulomatous cholecystitis. There is a known possible association of this uncommon condition with gallbladder cancer. The management of concomitant pathologies can present a real challenge to the multidisciplinary team, especially with large aneurysms.

    Kinases, which number > 500 in humans, are a class of enzymes that participate in an array of important functions within normal cellular physiology and during various pathological conditions. Due to the key role of kinases in the regulation of all aspects of cellular signaling and the well established contribution of kinase dysregulation to the etiology of many human pathologies, the development of kinase inhibitors has emerged as a therapeutic strategy for the treatment of human disease, including most notably oncology. Difficulties generating selective inhibitors have hampered their use in other therapeutic areas with less tolerance for off-target effects. However, with an increasing understanding of kinase structures and with the advent of newer inhibitor design strategies more highly selective inhibitors are beginning to emerge. This has prompted interest in utilizing kinase inhibitors in therapeutic areas beyond oncology, including acute and chronic neurodegenerative conditions for which disease modify therapies are lacking. This review provides a background in acute (i.e. brain ischemia and traumatic brain injury) and chronic (i.e. Alzheimer's, Parkinson's, Huntington's disease, amyotrophic lateral sclerosis and multiple sclerosis) neurodegenerative conditions. Then, the role of several kinase (i.e. JNK3, p38 MAPK, ERK, PKC, ROCKII, GSK3, Cdk5, MLK, EphB3 kinase, RIP1 kinase, LRRK2, TTBK1, ASK1, CK, DAPK, and PKN1) that could serve as potential therapeutic targets for these maladies are reviewed.

    Prone ventilation (PV) is a ventilatory strategy that frequently improves oxygenation and lung mechanics in critical illness, yet does not consistently improve survival. While the exact physiologic mechanisms related to these benefits remain unproven, one major theoretical mechanism relates to reducing the abdominal encroachment upon the lungs. Concurrent to this experience is increasing recognition of the ubiquitous role of intra-abdominal hypertension (IAH) in critical illness, of the relationship between IAH and intra-abdominal volume or thus the compliance of the abdominal wall, and of the potential difference in the abdominal influences between the extrapulmonary and pulmonary forms of acute respiratory distress syndrome. The present paper reviews reported data concerning intra-abdominal pressure (IAP) in association with the use of PV to explore the potential influence of IAH. While early authors stressed the importance of gravitationally unloading the abdominal cavity to unencumber the lung bases, this admonition has not been consistently acknowledged when PV has been utilized. Basic data required to understand the role of IAP/IAH in the physiology of PV have generally not been collected and/or reported. No randomized controlled trials or meta-analyses considered IAH in design or outcome. While the act of proning itself has a variable reported effect on IAP, abundant clinical and laboratory data confirm that the thoracoabdominal cavities are intimately linked and that IAH is consistently transmitted across the diaphragm--although the transmission ratio is variable and is possibly related to the compliance of the abdominal wall. Any proning-related intervention that secondarily influences IAP/IAH is likely to greatly influence respiratory mechanics and outcomes. Further study of the role of IAP/IAH in the physiology and outcomes of PV in hypoxemic respiratory failure is thus required. Theories relating inter-relations between prone positioning and the

    Acute abdominal compartment syndrome is most commonly associated with blunt abdominal trauma, although it has been seen after ruptured abdominal aortic aneurysm, liver transplantation, pancreatitis, and massive volume resuscitation. Acute abdominal compartment syndrome develops once the intra-abdominal pressure increases to 20-25 mmHg and is characterized by an increase in airway pressures, inadequate ventilation and oxygenation, altered renal function, and hemodynamic instability. This case report details the development of acute abdominal compartment syndrome during transurethral resection of the prostate with extra- and intraperitoneal bladder rupture under general anesthesia. The first signs of acute abdominal compartment syndrome in this patient were high peak airway pressures and difficulty delivering tidal volumes. Management of the compartment syndrome included re-intubation, emergent exploratory laparotomy, and drainage of irrigation fluid. Difficulty with ventilation should alert the anesthesiologist to consider abdominal compartment syndrome high in the list of differential diagnoses during any endoscopic bladder or bowel case.

    Mammals have four hypaxial muscle layers that wrap around the abdomen between the pelvis, ribcage, and spine. However, the marsupials have epipubic bones extending anteriorly into the ventral hypaxial layers with two additional muscles extending to the ventral midline and femur. Comparisons of South American marsupials to basal eutherians have shown that all of the abdominal hypaxials are active bilaterally in resting ventilation. However, during locomotion marsupials employ an asymmetrical pattern of activity as the hypaxial muscles form a crosscouplet linkage that uses the epipubic bone as a lever to provide long-axis support of the body between diagonal limb couplets during each step. In basal eutherians, this system shifts off the femur and epipubic bones (which are lost) resulting in a shoulder to pelvis linkage associated with shifts in both the positions and activity patterns of the pectineus and rectus abdominis muscles during locomotion. In this study, we present data on hypaxial function in two species (Pseudocheirus peregrinus and Trichosurus vulpecula) representing the two major radiations of possums in Australia: the Pseudocheiridae (within the Petauroidea) and the Phalangeridae. Patterns of gait, motor activity, and morphology in these two Australian species were compared with previous work to examine the generality of 1) the crosscouplet lever system as the basal condition for the Marsupialia and 2) several traits hypothesized to be common to all mammals (hypaxial tonus during resting ventilation, ventilation to step synchrony during locomotion, and bilateral transversus abdominis activity during locomotor expiration). Our results validate the presence of the crosscouplet pattern and basic epipubic bone lever system in Australian possums and confirm the generality of basal mammalian patterns. However, several novelties discovered in Trichosurus, reveal that it exhibits an evolutionary transition to intermediate eutherian-like morphological and motor

    The application of myeloablative Allo-SCT is limited by its associated morbidity and mortality. Reduced-intensity conditioning regimens attempt to diminish these, but are associated with a higher risk of disease relapse. Given the evidence of activity of clofarabine and cytarabine in myelodysplastic syndrome/acute myeloid leukemia (MDS/AML), we explored a novel reduced-intensity conditioning regimen based on this backbone. Patients received clofarabine 40 mg/m(2) i.v. on days -6 to -2, cytarabine 1 g/m(2) i.v. on days -6 to -2 and anti-thymocyte globulin (ATG) 1 mg/kg on day -4 and 2.5 mg/kg x 2 days on days -3 and -2. Seven patients were enrolled. Their median age was 54 years; three were with MDS and four with AML. The median duration of neutropenia was 14 days and that of thrombocytopenia was 22 days. Toxicities included hand-foot syndrome (57% grade 2), elevated alanine aminotransferase (ALT) (57% grade 3), elevated aspartate aminotransferase (AST) (86% grade 3) and hyperbilirubinemia (29% grade 3-5). No acute GVHD was observed. Enrollment to the trial was halted after three of the first seven patients expired on days +15, +26 and +32. Three of the four surviving patients have relapsed with a median TTP of 152 days. This regimen was not sufficiently immunosuppressive to ensure engraftment, and was associated with substantial morbidity and mortality.

    To present a case of torsion of a nonneoplastic intra-abdominal testis with an unusual clinical presentation.A 26-year-old active duty Navy Petty Officer presented to the emergency department on 3 occasions over a 5-day period with lower abdominal pain. Physical examination demonstrated acute tenderness in the left lower quadrant with sugestion of a normal spermatic cord and atrophic testis in the left scrotum. Computed tomography scan demonstrated an intra-abdominal lesion near the internal inguinal ring. The patient underwent surgical exploration through an inguinal incision. Torsion of a nonviable intra-abdominal testis was present. The scrotum contained only the vas deferens and cremasteric muscle. An orchiectomy was performed with removal of the vas deferens and other cord structures.The unusual clinical finding of acute torsion of an intra-abdominal testis, associated with an apparent atrophic scrotal testis, presented a confusing clinical picture. Computed tomography scan did not clarify the issue sufficiently to establish a definite preoperative diagnosis. Clinical suspicion prompted early surgical intervention. Review of the current literature produced 60 reported cases of torsion of an intra-abdominal testis. Two thirds of these involved testicular neoplasm, usually seminoma. Although the clinical presentation varied, most patients had recent onset of lower abdominal pain associated with tenderness and, in half the cases, a mass. Patients almost always presented with an absent scrotal testis on the involved side, and not infrequently reported previous surgery thought to be an orchiectomy.Diagnosis of an intra-abdominal testicular torsion is rare, particularly when no neoplasm is present. A high index of suspicion must be maintained whenever there is abdominal pain and undescended testis. The surgical history and imaging studies may not clarify a confusing clinical picture.

    Introduction The growing belief that endocrine abnormalities may underlie many mental conditions has led to increased use of imaging and hormonal assays in patients attending to psychiatric OPDs. People who are in an acute phase of a psychiatric disorder show Hypothalamic Pituitary Adrenal (HPA) axis hyperactivity, but the precise underlying central mechanisms are unclear. Aim To assess the pituitary gland volume variations in patients presenting with new onset acute psychiatric illness in comparison with age and gender matched controls by using MRI. Materials and Methods The study included 50 patients, with symptoms of acute psychiatric illness presenting within one month of onset of illness and 50 age and gender matched healthy controls. Both patients and controls were made to undergo MRI of the Brain. A 0.9 mm slices of entire brain were obtained by 3 dimensional T1 weighted sequence. Pituitary gland was traced in all sagittal slices. Anterior pituitary and posterior pituitary bright spot were measured separately in each slice. Volume of the pituitary (in cubic centimetre- cm3) was calculated by summing areas. Significance of variations in pituitary gland volumes was compared between the cases and controls using Analysis of Covariance (ANOVA). Results There were significantly larger pituitary gland volumes in the cases than the controls, irrespective of psychiatric diagnosis (ANOVA, f=15.56; p=0.0002). Pituitary volumes in cases were 15.36% (0.73 cm3) higher than in controls. Conclusion There is a strong likelihood of HPA axis overactivity during initial phase of all mental disorders along with increased pituitary gland volumes. Further studies including hormonal assays and correlation with imaging are likely to provide further insight into neuroanatomical and pathological basis of psychiatric disorders. PMID:28384955

    The aim of this study is to quantify the association between bioclimatic conditions and daily counts of admissions for non-fatal acute cardiovascular (acute coronary syndrome, arrhythmia, decompensation of heart failure) syndromes (ACS) registered by the two main hospitals in Heraklion, Crete Island, during a five-year period 2008-2012. The bioclimatic conditions analyzed are based on human thermal bioclimatic indices such as the Physiological Equivalent Temperature (PET) and the Universal Thermal Climate Index (UTCI). Mean daily meteorological parameters, such as air temperature, relative humidity, wind speed and cloudiness, were acquired from the meteorological station of Heraklion (Hellenic National Meteorological Service). These parameters were used as input variables in modeling the aforementioned thermal indices, in order to interpret the grade of the thermo-physiological stress. The PET and UTCI analysis was performed by the use of the radiation and bioclimate model, "RayMan", which is well-suited to calculate radiation fluxes and human biometeorological indices. Generalized linear models (GLM) were applied to time series of daily numbers of outpatients with ACS against bioclimatic variations, after controlling for possible confounders and adjustment for season and trends. The interpretation of the results of this analysis suggests a significant association between cold weather and increased coronary heart disease incidence, especially in the elderly and males. Additionally, heat stress plays an important role in the configuration of daily ACS outpatients, even in temperate climate, as that in Crete Island. In this point it is worth mentioning that Crete Island is frequently affected by Saharan outbreaks, which are associated in many cases with miscellaneous phenomena, such as Föhn winds - hot and dry winds - causing extreme bioclimatic conditions (strong heat stress). Taking into consideration the projected increased ambient temperature in the future, ACS

    Wandering spleen is a rare condition that can lead to splenic infarction or rupture if torsion persists. Early diagnosis and intervention are necessary, and abdominal ultrasonography and abdominal computed tomography are well accepted as the diagnostic imaging modalities. In this study, we present a boy with nic infarction due to acute torsion of a wandering spleen, after initial failure to demonstrate an ectopic spleen. Instead, acute torsion of the wandering spleen with spontaneous partial detorsion was incidentally found by multi-detector row CT with angiography. The patient was managed by splenectomy instead of splenopexy, because poor reperfusion after Laparoscopic detorsion.

    Objective: Scalloping of visceral organs is described in pseudomyxoma peritonei, malignant ascites, among other conditions, but not tuberculosis. Methods: We report findings from a retrospective study of patients with abdominal tuberculosis who had visceral scalloping on abdominal computed tomography (CT). Diagnosis of abdominal tuberculosis was made on the basis of combination of clinical, biochemical, radiological and microbiological criteria. The clinical data, hematological and biochemical parameters, and findings of chest X-ray, CT, Mantoux test, and HIV serology were recorded. Results: Of 72 patients with abdominal tuberculosis whose CT scans were included, seven patients had visceral scalloping. The mean age of these patients was 32.14 ± 8.43 years and four were men. While six patients had scalloping of liver, one had splenic scalloping. The patients presented with abdominal pain (all), abdominal distension (five patients), loss of weight or appetite (all), and fever (four patients). Mantoux test was positive in five, while none had HIV infection. The diagnosis was based on fluid (ascitic or collections) evaluation in four patients, ileo-cecal biopsy in one patient, fine needle aspiration from omental thickening in one patient, and sputum positivity for acid fast bacilli (AFB) in one patient. On CT examination, four patients had ascites, five had collections, one had lymphadenopathy, four had peritoneal involvement, three had pleural effusion, and two had ileo-cecal thickening. All except one patient received standard ATT for 6 months or 9 months (one patient). Pigtail drainage for collections was needed for two patients. Discussion: This report is the first description of visceral scalloping of liver and spleen in patients with abdominal tuberculosis. Previously, this finding has been reported primarily with pseudomyxoma peritonei and peritoneal carcinomatosis. Conclusion: Visceral scalloping may not conclusively distinguish peritoneal

    Misdiagnosis and under-detection of delirium may occur in many medical settings. This is important to address as delirium clearly increases risk of morbidity and mortality in such settings. This study assessed whether Veterans who screened positive on a delirium severity measure (Memorial Delirium Assessment Scale; MDAS) differed from those with and without corresponding medical documentation of delirium in terms of cognitive functioning, psychiatric/medical history, and medication use. A medical record review of 266 inpatients at a VA post-acute rehabilitation unit found that 10.9% were identified as delirious according to the MDAS and/or medical records. Of the Veterans who screened positive on the MDAS (N = 19), 68.4% went undetected by medical screening. Undetected cases had a higher number of comorbid medical conditions as measured by the Age-Adjusted Charlson Index (AACI) scores (median = 9, SD = 3.15; U = 5.5, p = .003) than medically documented cases. For Veterans with a score of 7 or greater on the AACI, the general relative risk for delirium was 4.46. Delirium is frequently under-detected in a post-acute rehabilitation unit, particularly for Veterans with high comorbid illness. The relative risk of delirium is up to 4.46 for those with high medical burden, suggesting the need for more comprehensive delirium screening in these patients. PMID:27902744

    2014-01-01

    Fear learning and regulation is a prominent model for describing the pathogenesis of anxiety disorders and stress-related psychopathology. Fear expression can be modulated using a number of regulatory strategies, including extinction, cognitive emotion regulation, avoidance strategies and reconsolidation. In this review, we examine research investigating the effects of acute stress and stress hormones on these regulatory techniques. We focus on what is known about the impact of stress on the ability to flexibly regulate fear responses that are acquired through Pavlovian fear conditioning. Our primary aim is to explore the impact of stress on fear regulation in humans. Given this, we focus on techniques where stress has been linked to alterations of fear regulation in humans (extinction and emotion regulation), and briefly discuss other techniques (avoidance and reconsolidation) where the impact of stress or stress hormones have been mainly explored in animal models. These investigations reveal that acute stress may impair the persistent inhibition of fear, presumably by altering prefrontal cortex function. Characterizing the effects of stress on fear regulation is critical for understanding the boundaries within which existing regulation strategies are viable in everyday life and can better inform treatment options for those who suffer from anxiety and stress-related psychopathology.

    Electronic Health Records (EHRs) hold great promise for secondary data reuse but have been reported to contain severe biases. The temporal characteristics of coding biases remain unclear. This study used a survival analysis approach to reveal temporal bias trends for coding acute diabetic conditions among 268 diabetes patients. For glucose-controlled ketoacidosis patients we found it took an average of 7.5 months for the incorrect code to be removed, while for glucose-controlled hypoglycemic patients it took an average of 9 months. We also examined blood glucose lab values and performed a case review to confirm the validity of our findings. We discuss the implications of our findings and propose future work. PMID:26958300

  5. The process of informed consent for urgent abdominal surgery

    2001-01-01

    Objectives—To assess perceptions of the informed consent process in patients undergoing urgent abdominal surgery. Design—A prospective observational study was carried out using structured questionnaire-based interviews. Patients who had undergone urgent abdominal surgery were interviewed in the postoperative period to ascertain their perceptions of the informed consent process. Replies were compared to responses obtained from a control group undergoing elective surgery, to identify factors common to the surgical process and those specific to urgent surgery. Patients' perceptions of received information were also compared to the information perceived to have been provided by the consent obtainers. Setting—Gastrointestinal surgical service of a university teaching hospital. Patients—Seventy-four consecutive patients undergoing urgent abdominal surgery and 80 control patients undergoing elective surgery. Main measurements—Principal outcome measures were patients' perceptions of factors interfering with the ability to give informed consent, assessment of the quality of informed consent and the degree of discussion of the expected outcomes. Results—Forty-nine of the seventy-four (66%) patients undergoing urgent surgery perceived that pain did not affect their ability to give informed consent. Twenty-seven reported an adverse effect of analgesia on the ability to give informed consent. Only 22% of patients undergoing urgent surgery perceived that there had been any discussion of potential side effects and complications of surgery. Conclusion–The majority of patients in this series with acute intra-abdominal surgical conditions perceive that they retain the ability to give informed consent for surgery. There is a need for improved discussion of therapeutic options and likely outcomes. Key Words: Informed consent • urgent abdominal surgery PMID:11417021

    Background and Aims: Considering the paucity of regional data, this study was designed to investigate the prevalence of post-operative pain and determine if there exists any correlation between the intensity of post-operative pain and patient's level of satisfaction with their pain management after inpatient abdominal surgery at an academic tertiary care government centre. Methods: Pain intensity was measured in 120 patients with numeric rating scale at the fifth post-operative hour, second and third post-operative day. A questionnaire was used to measure the level of satisfaction with nurse's and doctor's response to their pain and overall pain management. Results: The prevalence of post-operative pain was 84.17%, 92.5% and 96.66% at the fifth post-operative hour, second and third post-operative day, respectively. Less number of patients experienced severe intensity pain on the third post-operative day (P = 0.00046), whereas the number of patients experiencing mild pain increased (P < 0.000) compared to the fifth post-operative hour. The number of patients with complete analgesia decreased on the third post-operative day (P = 0.001 compared to fifth post-operative day). The Spearman correlation coefficient between pain score on the third post-operative day and level of satisfaction with nurse's response, doctor's response to pain and the overall pain management was − 0.0218 (P = 0.8107), 0.1307 (P = 0.1553) and 0.0743 (P = 0.4195), respectively. Conclusion: There is a high prevalence of acute post-operative pain in patients undergoing inpatient abdominal surgery at our institute. There is a weak correlation between the intensity of pain and level of satisfaction with pain management. PMID:27761037

    2016-09-01

    The authors report the case of 14-year-old girl with a history of myelomeningocele and previously shunt-treated hydrocephalus who presented with right-sided abdominal pain and subcutaneous emphysema that developed over a 1-week period. A CT scan of the patient's abdomen revealed a retained distal ventriculoperitoneal (VP) catheter with air tracking from the catheter to the upper chest wall. Given the high suspicion of the catheter being intraluminal, an exploratory laparotomy was performed and revealed multiple jejunal perforations. The patient required a partial small-bowel resection and reanastomosis for complete removal of the retained catheter. Six other similar cases of bowel perforation occurring in patients with abandoned VP and subdural-peritoneal shunts have been reported. The authors analyzed these cases with regard to age of presentation, symptomatic presentation, management, morbidity, and mortality. While there was 0% mortality associated with bowel perforation secondary to a retained distal VP catheter, the morbidity was significantly high and included peritonitis and small bowel resection.

  9. Impact of conditioning intensity and TBI on acute GVHD after hematopoietic cell transplantation.

    The impact of the conditioning intensity and TBI on acute GVHD (aGVHD) is still a matter of debate. We analyzed 6848 adult recipients who received allogeneic hematopoietic cell transplants (HCT) between 2006 and 2011 in Japan. The subjects were divided into groups who had received myeloablative conditioning (MAC) or reduced-intensity conditioning (RIC), either with or without TBI. There was a significant difference in the incidence of aGVHD 2-4 among the different conditioning types: 39% in TBI-MAC, 35% in TBI-RIC and 32% in both no-TBI MAC and no-TBI-RIC (P<0.001). In a multivariate analysis, TBI-MAC, but not no-TBI MAC, was significantly associated with an increased risk of aGVHD 2-4 (hazard ratio (HR) 1.33, P<0.01), whereas TBI-RIC was associated with an increased risk of GVHD 3-4 (HR 1.36, P=0.048). TBI-MAC and TBI-RIC were significantly associated with skin and gastrointestinal aGVHD. Subgroup analyses demonstrated that not only TBI-MAC, but also TBI-RIC, was significantly associated with aGVHD 2-4 in older patients. Furthermore, high-dose TBI only had an adverse impact on aGVHD 2-4 in HLA-matched HCT. Impacts of intensity and TBI on aGVHD differ by patient backgrounds, and this difference should be considered to establish a risk-adapted strategy for the prevention of aGVHD.

    This study compared the acute effect of strength, plyometric, and complex exercises (combined strength and plyometric exercise) in the countermovement jump (CMJ) and frequency speed of kick test (FSKT) and attempted to establish the best rest interval to maximize performance in the CMJ, number of kicks, and impact generated during FSKT. Eleven taekwondo athletes (mean ± SD; age: 20.3 ± 5.2 years; body mass: 71.8 ± 15.3 kg; height: 177 ± 7.2 cm) participated. One control and 9 experimental conditions were randomly applied. Each condition was composed of warm-up, conditioning activity (half-squat: 3 × 1 at 95% 1RM; jumps: 3 × 10 vertical jumps above 40-cm barrier; or complex exercise: half-squat 3 × 2 at 95% 1RM + 4 vertical jumps above 40-cm barrier), followed by different rest intervals (5-, 10-minute, and self-selected) before CMJ and FSKT. The conditions were compared using an analysis of variance with repeated measures, followed by Bonferroni's post hoc test. The alpha level was set at 5%. Significant difference was found in the number of kicks (F9,90 = 1.32; p = 0.239; and η2 = 0.116 [small]). The complex method with a 10-minute rest interval (23 ± 5 repetitions) was superior (p = 0.026) to the control (19 ± 3 repetitions), maximum strength with a self-selected rest interval (328 ± 139 seconds; 18 ± 2 repetitions) (p = 0.015), and plyometric with a 5-minute rest interval (18 ± 3 repetitions) (p < 0.001). Our results indicate that taekwondo athletes increased the number of kicks in a specific test by using the complex method when 10-minute rest interval was used.

    Number of cases of filariasis have been recently reported in the Hungarian medical literature, most of them caused by Dirofilaria repens . Dirofilaria repens is a mosquito-transmitted filarioid worm in the subcutaneous tissue of dogs and cats. Human infection manifests as either subcutaneous nodules or lung parenchymal disease, which may even be asymptomatic. The authors report a human Dirofilaria repens infection of the abdominal cavity in a 61-year-old man,who underwent laparotomy for acute abdomen. Intraoperatively, local peritonitis was detected caused by a white nemathhelminth, measured 8 cm in size. Histocytology confirmed that the infection was caused by Dirofilaria repens.

    These experiments were conducted to examine extinction and retention of a classically conditioned response in acute spinal cats. Conditioning was obtained by pairing a mild electrical stimulus to the superficial peroneal sensory nerve (CS) with a stronger electrical stimulus to the ankle skin (US) of the same leg. Subsequent extinction was produced by presenting CS-alone trials. In the first experiment, animals given massed extinction trials showed response decrements to base levels. Response decrements were not found in animals that received distributed extinction trials. In the second experiment, .5-, 1-, 2-, 3-, or 4-hr intervals between acquisition and extinction produced no significant differences in the extinction data. In the third experiment, animals received extinction trials immediately or 30 min after acquisition trials, followed by 20 additional extinction trials 30 min later. Analyses of these data indicated significant acquisition and extinction in the 10- and 20- acquisition trial groups. As in Experiment 2, varying the interval between acquisition and extinction did not produce any group differences in the extinction data. The results of these experiments demonstrate that response increases produced by paired trials in the spinal preparation do not decay spontaneously over time and are not caused by sensitization effects.

    Elderly patients (>60 years) with acute myeloid leukemia have a poor prognosis with a chemotherapy-alone approach. Allogeneic hematopoietic-cell transplantation (HCT) can improve overall survival (OS). However, myeloablative regimens can have unacceptably high transplant-related mortality (TRM) in an unselected group of older patients. Reduced-intensity conditioning (RIC) or nonmyeloablative (NMA) conditioning regimens preserve the graft-versus-leukemia effects but reduce TRM. NMA regimens result in minimal cytopenia and may not require stem cell support for restoring hematopoiesis. RIC regimens, intermediate in intensity between NMA and myeloablative regimens, can cause prolonged myelosuppresion and usually require stem cell support. A few retrospective and prospective studies suggest a possibility of lower risk of relapse with myeloablative HCT in fit older patients with lower HCT comorbidity index; however, RIC and NMA HCTs have an important role in less-fit patients and those with significant comorbidities because of lower TRM. Whether early tapering of immunosuppression, monitoring of minimal residual disease, and post-transplant maintenance therapy can improve the outcomes of RIC and NMA HCT in elderly patients will require prospective trials.

    The study examined whether or not acute exposure to unfamiliar hot or cold conditions impairs performance of highly skilled coordinative activities and whether prior physical self-efficacy beliefs were associated with task completion. Nineteen volunteers completed both Guitar Hero and Archery activities as a test battery using the Nintendo Wii console in cold (2 degrees C), neutral (20 degrees C), and hot (38 degrees C) conditions. Participants all completed physical self-efficacy questionnaires following experimental familiarization. Performances of both Guitar Hero and Archery significantly decreased in the cold compared with the neutral condition. The cold trial was also perceived as the condition requiring both greater concentration and effort. There was no association between performance and physical self-efficacy. Performance of these coordinative tasks was compromised by acute (nonhypothermic) exposure to cold; the most likely explanation is that the cold condition presented a greater challenge to attentional processes as a form of environmental distraction.

    Animal models of hematopoietic and gastrointestinal acute radiation syndromes (ARS) have been characterized to develop medical countermeasures. Acute radiation-induced decrease of intestinal absorptive function has been correlated to a decrease in the number of intestinal crypt cells resulting from apoptosis and enterocyte mass reduction. Citrulline, a noncoded amino acid, is produced almost exclusively by the enterocytes of the small intestine. Citrullinemia has been identified as a simple, sensitive and suitable biomarker for radiation-induced injury associated with gastrointestinal ARS (GI-ARS). Here we discuss the effect of radiation on plasma citrulline levels in three different species, C57BL/6 mice, Göttingen minipigs and rhesus nonhuman primates (NHPs), measured by liquid chromatography tandem mass spectrometry (LC-MS/MS). The effects of experimental study conditions such as feeding and anesthesia were also examined on plasma citrulline levels in the NHPs. Both the mice and Göttingen minipigs were partial-body irradiated (PBI) with doses from 13-17 Gy and 8-16 Gy, respectively, whereas NHPs were total-body irradiated (TBI) with doses from 6.72-13 Gy. Blood samples were taken at different time points and plasma citrulline levels were measured in the three species at baseline and after irradiation. Basal plasma citrulline concentrations (mean ± SEM) in mice and minipigs were 57.8 ± 2.8 μM and 63.1 ± 2.1 μM, respectively. NHPs showed a basal plasma citrulline concentration of 32.6 ± 0.7 μM, very similar to that of humans (∼40 μM). Plasma citrulline progressively decreased after irradiation, reaching nadir values between day 3.5 and 7. The onset of citrulline recovery was observed earlier at lower radiation doses, while only partial citrulline recovery was noted at higher radiation doses in minipigs and NHPs, complete recovery was noted in mice at all doses. Plasma citrulline levels in NHPs anesthetized with ketamine and acepromazine significantly

    Aortocaval fistula (ACF) is a rare complication of abdominal aortic aneurysm (AAA). We report the endovascular repair of an AAA rupture into the inferior vena cava. A 78-year-old woman was admitted to our hospital for acute hypotension. She presented with a pulsatile abdominal mass and became rapidly anuric. Abdominal computed tomography (CT) showed an AAA rupture into the inferior vena cava. The features of the AAA made it suitable for endovascular repair. To prevent pulmonary embolism caused by the presence of sac thrombosis near the vena cava lumen, a temporary vena cava filter was deployed before the procedure. A bifurcated stent-graft was placed with the patient under local anaesthesia, and the AAA was successfully treated. A transient type II endoleak was detected on CT 3 days after endograft placement. At routine follow-up 6 and 12 months after the procedure, the patient was in good clinical condition, and the type II endoleak had sealed completely. Endovascular treatment offers an attractive therapeutic alternative to open repair in case of ACF; however, only small numbers of patients have been treated, and long-term follow-up interval is lacking.

  17. Acute Degradation of Surface-Bound Unsaturated Polyolefins in Common Solvents under Ambient Conditions

    2009-01-01

    We describe the detachment of covalently grafted polybutadiene and polynorbornenechains – which were prepared by surface-initiated ring-opening metathesis polymerization (SiROMP) – from Si/SiO2 substrates upon brief exposure to common solvents in air. Degradation and disappearance of grafted polybutadiene films after successive rinses with dichloromethane was monitored by ellipsometry. Changes in surface topography were analyzed by atomic force microscopy. The rapid auto-oxidation of allylic carbon-hydrogen bonds renders these thin films extremely susceptible to degradation under ambient conditions. Polymers in the tethered state suffer more acute degradation (on the time scale of seconds) compared to those dissolved in solution (not detectable after days). To prevent degradation, unsaturated polymersprepared by SiROMP and the subsequent conversion (of unsaturated groups) need to be carriedout under inert atmosphere. For example, smooth polybutadiene thin films of ~ 100 Å thick were covalently attached to silicon substrates via SiROMP of cyclooctadiene in the vapor phase. Solvent rinsing to remove unreacted monomers and free oligomers/polymers was carried out prior to the conversion of double bonds to epoxide groups. When these steps were carried out under nitrogen, negligible film loss was observed and surface topography of the thin film was preserved. Once the unsaturation was removed from polybutadiene, the epoxidized and hydroxylated polybutadiene films were stable toward solvent exposure in air. PMID:19788207

    Metabolic acidosis is associated with most severe malaria deaths in African children, and most deaths occur before maximum antimalarial action is achieved. Thus, specific acidosis treatment may reduce mortality. However, the underlying mechanisms remain poorly understood and no specific interventions have been developed. A detailed characterisation of this acidosis is critical in treatment development. We used the traditional and Stewart's approach to characterise acidosis in consecutive paediatric admissions for malaria and other acute non-surgical conditions to Kilifi District Hospital in Kenya. The overall acidosis prevalence was 21%. Gastroenteritis had the highest prevalence (61%). Both the mean albumin-corrected anion gap and the strong ion gap were high (>13 mmol/l and >0 mmol/l, respectively) in malaria, gastroenteritis, lower respiratory tract infection and malnutrition. Presence of salicylate in plasma was not associated with acidosis but was associated with signs of severe illness (odds ratio 2.11, 95% CI 1.1-4.2). In malaria, mean (95% CI) strong ion gap was 15 (14-7) mmol/l, and lactate, creatinine and inorganic phosphorous explained only approximately 40% of the variability in base excess (adjusted R2 = 0.397). Acidosis may be more common than previously recognised amongst paediatric admissions in Africa and is characterised by the presence of currently unidentified strong anions. In malaria, lactate and ketones, but not salicylate, are associated with acidosis. However, unidentified anions may be more important.

    Background: Remote ischemic conditioning (RIC) has been shown to be a practical method for protecting the heart from ischemic/reperfusion (I/R) injury. In the present study, we investigated whether or not the combination of RIC and Astragaloside IV (AS-IV) could improve cardioprotection against acute myocardial infarction (AMI)-induced heart failure (HF) when compared with individual treatments. Material and Methods: A rat model of AMI was established via permanent ligation of the left anterior descending coronary artery (LAD). Postoperatively, the rats were randomly grouped into a sham group (n=10), a model group (n=15), an AS-IV alone group (n=15), an RIC alone group (n=15) and a combined treatment group (AS-IV+RIC; n=15). All treatments were administered for 2 weeks. Results: After treatment for 2 weeks, the survival rate was improved, the cardiac function was preserved and the infarcted size was limited in AS-IV alone and RIC alone treatment groups compared to the model group, whereas the combined treatment yielded the most optimal protective effects. Additional studies suggested that AS-IV enhanced the cardioprotective effects of RIC by alleviating myocardial fibrosis, suppressing inflammation, attenuating apoptosis and ameliorating impairment of the myocardial ultrastructural. Conclusion: AS-IV enhances the cardioprotective effects of RIC against AMI-induced HF and ventricular remodeling, which represents a potential therapeutic approach for preserving cardiac function and improving the prognosis of AMI.

    Women and female rodents are more responsive to the subjective effects of psychostimulant drugs of abuse compared to males. A growing body of literature supports a role for estradiol as a mechanism underlying these sex differences. However, little is known about the influence of acute elevations in levels of estradiol on drug conditioned behaviors. The aim of the present study was to evaluate the influence of an acute increase in systemic estradiol levels on the expression of cocaine conditioned place preference (CPP). Using a six day conditioning procedure, ovariectomized (OVX) female rats were conditioned with one of four doses of cocaine (2.5, 5, 10, or 15mg/kg) to associate one of two large chambers of a CPP apparatus with cocaine or saline. Thirty minutes prior to the start of the CPP preference test, rats were pretreated with either 5μg estradiol benzoate (EB) or peanut oil (PO). PO-treated rats expressed a significant preference for only the mid-range conditioning doses of cocaine (5 and 10mg/kg). However, acute EB treatment resulted in a rightward shift in the cocaine dose-response curve; rats demonstrated a significant preference at only the moderate and high conditioning doses of cocaine (10 and 15mg/kg). These findings demonstrate that acute elevations in estradiol may dampen the expression of conditioned responses to cocaine's secondary rewards at lower conditioning doses of the drug and facilitate CPP at higher doses while estradiol deficiency decreases the threshold dose of cocaine necessary to induce CPP.

    The infrequent occurrence of herpes simplex virus (HSV) hepatitis in healthy women in comparison with the high prevalence of HSV infections suggests that, in addition to deranged immunity, an underlying condition in the liver might be necessary to develop HSV hepatitis. We report the case of a 28-year-old pregnant woman in the 28 (th) week of gestation. Following HSV type 2 infection of the uterine cervix, acute liver failure developed, necessitating urgent liver transplantation. In addition to fulminant HSV type 2 hepatitis, the explanted liver also showed the histological features of acute fatty liver of pregnancy. The presented case suggests a possible pathogenetic role of acute fatty liver of pregnancy in the development of fulminant HSV hepatitis following recurrent infection with HSV in healthy pregnant women. We believe that early histopathological diagnosis, followed by specific antiviral treatment and liver transplantation in selected patients may improve the clinical outcome of otherwise almost uniformly fatal HSV hepatitis.

    Rationale Remote ischemic per-conditioning-causing transient limb ischemia to induce ischemic tolerance in other organs-reduces final infarct size in animal stroke models. Aim To evaluate whether remote ischemic per-conditioning during acute ischemic stroke (<6 h) reduces brain infarct size at 24 h. Methods and design This study is being performed in five French hospitals using a prospective randomized open blinded end-point design. Adults with magnetic resonance imaging confirmed ischemic stroke within 6 h of symptom onset and clinical deficit of 5-25 according to National Institutes of Health Stroke Scale will be randomized 1:1 to remote ischemic per-conditioning or control (stratified by center and intravenous fibrinolysis use). Remote ischemic per-conditioning will consist of four cycles of electronic tourniquet inflation (5 min) and deflation (5 min) to a thigh within 6 h of symptom onset. Magnetic resonance imaging is repeated 24 h after stroke onset. Sample size estimates For a difference of 15 cm(3) in brain infarct growth between groups, 200 patients will be included for 5% significance and 80% power. Study outcomes The primary outcome will be the difference in brain infarct growth from baseline to 24 h in the intervention versus control groups (by diffusion-weighted image magnetic resonance imaging). Secondary outcomes include: National Institutes of Health Stroke Scale score absolute difference between baseline and 24 h, three-month modified Rankin score and daily living activities, mortality, and tolerance and side effects of remote ischemic per-conditioning. Discussion The only remote ischemic per-conditioning trial in humans with stroke did not show remote ischemic per-conditioning to be effective. REmote iSchemic Conditioning in acUtE BRAin INfarction, which has important design differences, should provide more information on the use of this intervention in patients with acute ischemic stroke.

    Acute appendicitis is a common surgical condition that is usually managed with early surgery, and is associated with low morbidity and mortality. However, some patients may have atypical symptoms and physical findings that may lead to a delay in diagnosis and increased complications. Atypical presentation may be related to the position of the appendix. Ascending retrocecal appendicitis presenting with right upper abdominal pain may be clinically indistinguishable from acute pathology in the gallbladder, liver, biliary tree, right kidney and right urinary tract. We report a series of four patients with retrocecal appendicitis who presented with acute right upper abdominal pain. The clinical diagnoses at presentation were acute cholecystitis in two patients, pyelonephritis in one, and ureteric colic in one. Ultrasound examination of the abdomen at presentation showed subhepatic collections in two patients and normal findings in the other two. Computed tomography (CT) identified correctly retrocecal appendicitis and inflammation in the retroperitoneum in all cases. In addition, abscesses in the retrocecal space (n = 2) and subhepatic collections (n = 2) were also demonstrated. Emergency appendectomy was performed in two patients, interval appendectomy in one, and hemicolectomy in another. Surgical findings confirmed the presence of appendicitis and its retroperitoneal extensions. Our case series illustrates the usefulness of CT in diagnosing ascending retrocecal appendicitis and its extension, and excluding other inflammatory conditions that mimic appendicitis. PMID:19630119

    Abdominal incisional hernia is a common complication after open abdominal operations. Laparoscopic procedures have obvious mini-invasive advantages for surgical treatment of abdominal incisional hernia, especially to cases with big hernia defect. Laparoscopic repair of incisional hernia has routine mode but the actual operations will be various according to the condition of every hernia. Key points of these operations include design of the position of trocars, closure of defects and fixation of meshes. The details of these issues and experiences of perioperative evaluation and treatment will be talked about in this article. PMID:27761446

    Effects of remote ischemic conditioning (RIC) in acute myocardial infarction (AMI) patients remain conflicting. We performed this meta-analysis of randomized clinical trials (RCTs) to evaluate the benefits of the RIC in patients with AMI. Potentially relevant RCTs were identified by searching PubMed, Embase, Cochrane Library, VIP, CNKI, and Wanfang database until November 2016. RCTs evaluating RIC using intermittent limb ischemia-reperfusion in AMI patients were included. Thirteen RCTs were identified and analyzed. Meta-analysis showed that RIC significantly reduced the area under the curve (AUC) of creatine kinase-myocardial band (CK-MB) (standardized mean difference [SMD] −0.29; 95% confidence intervals [CI] −0.44 to −0.14; P = 0.0002) and AUC of troponin T (SMD −0.22; 95% CI −0.37 to −0.08; P = 0.003). Risk ratio (RR) for ≥70% ST-segment resolution favored RIC group than the control group (RR 1.39; 95% CI 1.03–1.86; P = 0.03). RIC also significantly reduced all-cause mortality (RR 0.33; 95%CI 0.17–0.64; P = 0.001). Subgroup analyses on the CK-MB AUC and ST-segment resolution ≥70% rate showed that the effects of RIC appeared to be affected by the limb used, duration of RIC, and clinical setting. RIC may offer cardioprotective effects by improving ST-segment resolution and reducing the infarct size in AMI patients. PMID:28272470

    The aim of this study was to evaluate the relationship between weather conditions and daily emergency ambulance calls for acute coronary syndromes (ACS). The study included data on 3631 patients who called the ambulance for chest pain and were admitted to the department of cardiology as patients with ACS. We investigated the effect of daily air temperature ( T), barometric pressure (BP), relative humidity, and wind speed (WS) to detect the risk areas for low and high daily volume (DV) of emergency calls. We used the classification and regression tree method as well as cluster analysis. The clusters were created by applying the k-means cluster algorithm using the standardized daily weather variables. The analysis was performed separately during cold (October-April) and warm (May-September) seasons. During the cold period, the greatest DV was observed on days of low T during the 3-day sequence, on cold and windy days, and on days of low BP and high WS during the 3-day sequence; low DV was associated with high BP and decreased WS on the previous day. During June-September, a lower DV was associated with low BP, windless days, and high BP and low WS during the 3-day sequence. During the warm period, the greatest DV was associated with increased BP and changing WS during the 3-day sequence. These results suggest that daily T, BP, and WS on the day of the ambulance call and on the two previous days may be prognostic variables for the risk of ACS.

    The aim of this study was to determine acute toxicity in the post larvae of the white shrimp Litopenaeus vannamei after 96 h of exposure to dissolved arsenic under three different temperatures and salinity conditions. Recent reports have shown an increase in the presence of this metalloid in coastal waters, estuaries, and lagoons along the Mexican coast. The white shrimp stands out for its adaptability to temperature and salinity changes and for being the main product for many commercial fisheries; it has the highest volume of oceanic capture and production in Mexican shrimp farms. Lethal concentrations (LC50-96 h) were obtained at nine different combinations (3 × 3 combinations in total) of temperature (20, 25, and 30 °C) and salinity (17, 25, and 33) showing mean LC50-96 h values (±standard error) of 9.13 ± 0.76, 9.17 ± 0.56, and 6.23 ± 0.57 mgAs L(-1)(at 20 °C and 17, 25, and 33 salinity); 12.29 ± 2.09, 8.70 ± 0.82, and 8.03 ± 0.59 mgAs L(-1) (at 25 °C and 17, 25, and 33 salinity); and 7.84 ± 1.30, 8.49 ± 1.40, and 7.54 ± 0.51 mgAs L(-1) (at 30 °C and 17, 25, and 33 salinity), respectively. No significant differences were observed for the optimal temperature and isosmotic point of maintenance (25 °C-S 25) for the species, with respect to the other experimental conditions tested, except for at 20 °C-S 33, which was the most toxic. Toxicity under 20 °C-S 33 conditions was also higher than 25 °C-S 17 and 20 °C (S 17 or 25). The least toxic condition was 25 °C-S 17. All this suggests that the toxic effect of arsenic is not affected by temperature changes; it depends on the osmoregulatory pattern developed by the shrimp, either hyperosmotic at low salinity or hiposmotic at high salinity, as observed at least on the extreme salinity conditions here tested (17 and 33). However, further studies testing salinities near the isosmotic point (between 20 and 30 salinities) are needed to

    Duodenal perforation after a blunt abdominal trauma is a rare emergency situation that can result in life-threatening complications. We report on a woman who had a perforation of the duodenum after a supposed mild blunt abdominal trauma. Unremarkable at the initial presentation, the patient presented with acute abdominal pain and a retroperitoneal abscess five days after the initial trauma. The duodenal repair was performed with a Roux-Y anastomosis. Difficulties in diagnosis are very common, but the early recognition of the rupture is essential. The contrast-enhanced CT scan is the gold standard for diagnosis. Surgical management depends on the severity of the trauma and must be chosen on an individual basis.

    Abdominal apoplexy is a rare hemorrhagic condition involving the small arteries or veins within the abdominal cavity. A high degree of clinical suspicion, followed by appropriate diagnostic workup and therapeutic intervention, is critical, as nonoperative mortality approaches 100%. Contrary to most previously reported cases, which were associated with hemoperitoneum, we present a patient in which gastroduodenal artery dissection resulted in an organized retroperitoneal hematoma with local compression of the duodenum and subsequent bowel obstruction, resulting in vomiting, aspiration, and death.

    Presented are the results of experimental research on 144 animals (the rats Wistar), on whom was carried out resection of a part of large intestine and a intestinal anastamosis was formed in the presents of acute intestinal obstruction and peritonitis. The sanitation of abdominal cavity in the basic group of animals (74) was performed using sodium hypochlorite solution and dissolved ozone. The intestinal lavage was carried out by dissolved ozone with the subsequent introduction of ozonized oil Ozonide in the area of intestinal anastamosis. The combined application of ozone and sodium produces an expressed samative effect which leads to healing of intestinal anastamosis and decreases unstability of intestinal sutures and mortality.

    Appendiceal intussusception is a rare condition that can occur at any age. Only a few cases have been reported, and most are found during surgery. The therapeutic approach is usually surgical, ranging from an appendectomy to a hemicolectomy, primarily for biopsy and to rule out possible malignancy. Three cases of children under 14 years who underwent surgery for acute abdominal pain located in the right iliac fossa are presented; one with preoperative diagnosis by ultrasound, and the other two with positive intraoperative findings of intussusception of the cecal appendix, with acute appendicitis being histologically confirmed.

    There is evidence that pain can impact cognitive function in people. The present study evaluated whether Pavlovian fear conditioning in rats would be reduced if conditioning were followed by persistent inflammatory pain induced by a subcutaneous injection of dilute formalin or complete Freund's adjuvant (CFA) on the dorsal lumbar surface of the back. Formalin-induced pain specifically impaired contextual fear conditioning but not auditory cue conditioning (Experiment 1A). Moreover, formalin pain only impaired contextual fear conditioning if it was initiated within 1h of conditioning and did not have a significant effect if initiated 2, 8 or 32 h after (Experiments 1A and 1B). Experiment 2 showed that formalin pain initiated after a session of context pre-exposure reduced the ability of that pre-exposure to facilitate contextual fear when the rat was limited to a brief exposure to the context during conditioning. Similar impairments in context- but not CS-fear conditioning were also observed if the rats received an immediate post-conditioning injection with CFA (Experiment 3). Finally, we confirmed that formalin and CFA injected s.c. on the back induced pain-indicative behaviours, hyperalgesia and allodynia with a similar timecourse to intraplantar injections (Experiment 4). These results suggest that persistent pain impairs learning in a hippocampus-dependent task, and may disrupt processes that encode experiences into long-term memory.

    AIMS—To determine the clinical course of childhood abdominal migraine, seven to 10 years after the diagnosis.
METHODS—A total of 54 children with abdominal migraine were studied; 35 were identified from a population survey carried out on Aberdeen schoolchildren between 1991 and 1993, and 19 from outpatient records of children in the same age group who had attended the Royal Aberdeen Children's Hospital. Controls were 54 children who did not have abdominal pain in childhood, matched for age and sex, obtained from either the population survey or the patient administration system. Main outcome measures were presence or resolution of abdominal migraine and past or present history of headache fulfilling the International Headache Society (IHS) criteria for the diagnosis of migraine.
RESULTS—Abdominal migraine had resolved in 31 cases (61%). Seventy per cent of cases with abdominal migraine were either current (52%) or previous (18%) sufferers from headaches that fulfilled the IHS criteria for migraine, compared to 20% of the controls.
CONCLUSIONS—These results support the concept of abdominal migraine as a migraine prodrome, and suggest that our diagnostic criteria for the condition are robust.

    Renal artery thrombosis is a rare, but serious and often under-diagnosed condition. We report a case of bilateral renal artery thrombosis secondary to acute necrotizing pancreatitis. A 66-year-old female presented with abdominal pain and acute kidney injury (AKI). A renal biopsy showed organized intraluminal thrombi and a computer tomography scan of the abdomen showed bilateral renal artery thrombosis. Emergent laprotomy showed necrosed pancreas. Doppler studies showed deep vein thrombosis of the lower extremities and internal jugular vein thrombosis. Workup for hypercoagulability was unremarkable. The final diagnosis was AKI secondary to bilateral renal artery thrombosis probably due to hypercoagulability of acute necrotizing pancreatitis. PMID:26064514

    The reported incidence of inflammatory abdominal aortic aneurysm (IAAA) is from 2% to 14% of patients with abdominal aortic aneurysm and the etiology of this disease is still discussed--according to the literature several pathogenic theories have been proposed. From 1992 to 1997 32 patients with IAAA were operated on. The patients were mostly symptomatic--abdominal pain was present in 68.75% cases, back pain in 31.25%, fever in 12.5% and weight loss in 6.25% of the operated patients. In all the patients ultrasound examination was performed, in 4 patients CT and in 3 cases urography. All the patients were operated on and characteristic signs of inflammatory abdominal aortic aneurysm like: thickened aortic wall, perianeurysmal infiltration or retroperitoneal fibrosis with involvement of retroperitoneal structures were found. In all cases surgery was performed using transperitoneal approach; in three cases intraoperatively contiguous abdominal organs were injured, which was connected with their involvement into periaortic inflammation. In 4 cases clamping of the aorta was done at the level of the diaphragmatic hiatus. 3 patients (9.37%) died (one patient with ruptured abdominal aortic aneurysm). Authors present diagnostic procedures and the differences in the surgical tactic, emphasizing the necessity of the surgical therapy in patients with inflammatory abdominal aortic aneurysm.

    In anesthetized male rats the arterial blood pressure in femoral artery and electrocardiogram in standard leads were recorded uninterruptedly for 1-1.5 h under conditions of acute nitrite intoxication produced by a subcutaneous injection of water solution of sodium nitrite (donor of nitric oxide) at concentrations of 10, 30, and 50 mg/kg body mass. Results of the study have shown dose-dependent changes of arterial pressure as well as of time and amplitude characteristics of electrocardiogram under effect of NaNO2. At the threshold hypoxic dose, an increase of amplitude of R and S waves was observed by the 30-45th min, while at the maximal NaNO2 dose, amplitude of all waves rose by the 15th min of intoxication. High nitric doses often caused an increase of the ST segment above the isoelectric line and a rise of the amplitude of the T wave, on which a notch appeared in some cases. The change of the ECG time parameters was expressed in the dose-dependent development of bradycardia for the first 4-7 min; its level correlated with the progressively decreasing arterial pressure in the beginning (the 2-4th min) of nitrite intoxication. Variation analysis of heart rate spectral characteristics by Baevskii has revealed a rise of the total spectral power of pulse oscillations. Under effect of nitrite, in the spectrum of cardiointervals, quent recovery of the normal ECG spectrum in the end of the experimental period. The maximal nitrite dose produced more pronounced shifts of the heart rate spectrum towards the LF and VLF diapasons that were not restored for 1 h of experiment. Transitory processes of readjustment of the cardiac rhythm had discrete character. The nitrite dose of 50 mg/kg body mass increased the RR-interval after 4-7 min with amplitude steps of 3-5 imp/s and the time constant of 20-40 s. The revealed ECG changes had the reflex (enhancement of parasympathetic tonus) and metabolic (the hypoxic and histotoxic damage of myocardium) nature.

    Acute phase proteins (APPs) are a group of circulating plasma proteins which undergo changes quantitatively or qualitatively at the time of inflammation. Many of these APPs are glycosylated, and it has been shown that alterations in glycosylation may occur in inflammatory and malignant conditions. Changes in glycosylation have been studied as potential biomarkers in cancer and also in chronic inflammatory conditions and have been shown to correlate with disease severity in certain conditions. Serine protease inhibitors (serpins), many of which are also APPs, are proteins involved in the control of proteases in numerous pathways. Alpha-1 Antitrypsin (AAT) is the most abundant serpin within the circulation and is an APP which has been shown to increase in response to inflammation. The primary role of AAT is maintaining the protease/antiprotease balance in the lung, but it also possesses important anti-inflammatory and immune-modulating properties. Several glycoforms of AAT exist, and they possess differing properties in regard to plasma half-life and stability. Glycosylation may also be important in determining the immune modulatory properties of AAT. The review will focus on the role and importance of glycosylation in acute phase proteins with particular attention to AAT and its use as a biomarker of disease. The review describes the processes involved in glycosylation, how glycosylation changes in differing disease states, and the alterations that occur to glycans of APPs with disease and inflammation. Finally, the review explores the importance of changes in glycosylation of AAT at times of inflammation and in malignant conditions and how this may impact upon the functions of AAT.

    ABSTRACT There is a growing request for measuring intra-abdominal pressure in critically ill patients with acute abdominal pain to be clarified. Summarizing the research results on measurement of vesical intra-abdominal pressure and analyzing the level of evidence were the purposes of this integrative literature review, carried out based on the databases LILACS, MEDLINE and PubMed, from 2005 to July 2012. Twenty articles were identified, in that, 12 literature reviews, 4 descriptive and exploratory studies, 2 expert opinions, one prospective cohort study and one was an experience report. The vesical intra-abdominal pressure measurement was considered gold standard. There are variations in the technique however, but some common points were identified: complete supine position, in absence of abdominal contracture, in the end of expiration and expressed in mmHg. Most research results indicate keeping the transducer zeroed at the level of the mid-axillary line at the iliac crest level, and instill 25mL of sterile saline. Strong evidence must be developed.

    A diagnostic approach based on clinical and radiographic examinations for evaluation of young foals and small ponies with acute abdominal discomfort is presented. Standing right to left lateral abdominal radiographs were taken of 54 foals and 6 ponies using a previously described technique. Interpretation of the radiographs was in conjunction with all clinical and laboratory findings and patient management. Using this approach, the site and cause of acute abdominal discomfort could be diagnosed accurately in 55 of 60 (91%) patients as confirmed by clinical, surgical or necropsy findings. Typical radiographs and photographs taken at surgery or at necropsy are presented. Typical radiographic findings, their interpretation and possible underlying gastrointestinal diseases are listed. The incorporation of standing lateral abdominal radiography in the clinical evaluation of foals and ponies with acute abdominal diseases gives findings of high diagnostic significance and should contribute to clinical decision-making. Abdominal radiography can replace data from rectal palpation in foals and ponies.

    Background Allogeneic hematopoietic stem cell transplantation with HLA-identical donors has been established for the treatment of acute myeloid leukemia patients for over 30 years with a cure rate of 50% to 60%. Objectives To analyze the overall survival of patients and identify factors that influence the outcomes of this type of transplant in patients in 1st complete remission who received a busulfan and melphalan combination as conditioning regimen. Methods Twenty-five consecutive patients with acute myeloid leukemia were enrolled between 2003 and 2008. The median age was 34 years old (Range: 16 - 57 years). All patients received cyclosporine and methotrexate for prophylaxis against graft-versus-host disease. Median neutrophil engraftment time was 16 days (Range: 7 - 22 days) and 17 days (Range: 7 - 46 days) for platelets. Sinusoidal obstructive syndrome was observed in three patients, seven had grade II acute graft-versus-host disease and one extensive chronic graft-versus-host disease. Results The overall survival by the Kaplan-Meier method was 48% after 36 months with a plateau at 36 months after transplantation. Intensive consolidation with high-dose arabinoside resulted in an improved survival (p-value = 0.0001), as did grade II acute graft-versus-host disease (p-value = 0.0377) and mild chronic graft-versus-host disease (p-value < 0.0001). Thirteen patients died, five due to infection within 100 days of transplant, two due to hemorrhages, one to infection and graftversus-host disease and three relapses followed by renal failure (one) and infection (two). The cause of death could not be determined for two patients. Conclusion The busulfan and melphalan conditioning regimen is as good as other conditioning regimens providing an excellent survival rate.

  4. Mechanical ventilation in abdominal surgery.

    One of the key challenges in perioperative care is to reduce postoperative morbidity and mortality. Patients who develop postoperative morbidity but survive to leave hospital have often reduced functional independence and long-term survival. Mechanical ventilation provides a specific example that may help us to shift thinking from treatment to prevention of postoperative complications. Mechanical ventilation in patients undergoing surgery has long been considered only as a modality to ensure gas exchange while allowing maintenance of anesthesia with delivery of inhaled anesthetics. Evidence is accumulating, however, suggesting an association between intraoperative mechanical ventilation strategy and postoperative pulmonary function and clinical outcome in patients undergoing abdominal surgery. Non-protective ventilator settings, especially high tidal volume (VT) (>10-12mL/kg) and the use of very low level of positive end-expiratory pressure (PEEP) (PEEP<5cmH2O) or no PEEP, may cause alveolar overdistension and repetitive tidal recruitment leading to ventilator-associated lung injury in patients with healthy lungs. Stimulated by previous findings in patients with acute respiratory distress syndrome, the use of lower tidal volume ventilation is becoming increasingly more common in the operating room. However, lowering tidal volume, though important, is only part of the overall multifaceted approach of lung protective mechanical ventilation. In this review, we aimed at providing the most recent and relevant clinical evidence regarding the use of mechanical ventilation in patients undergoing abdominal surgery.

  5. Acute and chronic effects of selective serotonin reuptake inhibitor treatment on fear conditioning: implications for underlying fear circuits.

    PubMed

    Burghardt, N S; Bauer, E P

    2013-09-05

    Selective serotonin reuptake inhibitors (SSRIs) are widely used for the treatment of a spectrum of anxiety disorders, yet paradoxically they may increase symptoms of anxiety when treatment is first initiated. Despite extensive research over the past 30 years focused on SSRI treatment, the precise mechanisms by which SSRIs exert these opposing acute and chronic effects on anxiety remain unknown. By testing the behavioral effects of SSRI treatment on Pavlovian fear conditioning, a well characterized model of emotional learning, we have the opportunity to identify how SSRIs affect the functioning of specific brain regions, including the amygdala, bed nucleus of the stria terminalis (BNST) and hippocampus. In this review, we first define different stages of learning involved in cued and context fear conditioning and describe the neural circuits underlying these processes. We examine the results of numerous rodent studies investigating how acute SSRI treatment modulates fear learning and relate these effects to the known functions of serotonin in specific brain regions. With these findings, we propose a model by which acute SSRI administration, by altering neural activity in the extended amygdala and hippocampus, enhances both acquisition and expression of cued fear conditioning, but impairs the expression of contextual fear conditioning. Finally, we review the literature examining the effects of chronic SSRI treatment on fear conditioning in rodents and describe how downregulation of N-methyl-d-aspartate (NMDA) receptors in the amygdala and hippocampus may mediate the impairments in fear learning and memory that are reported. While long-term SSRI treatment effectively reduces symptoms of anxiety, their disruptive effects on fear learning should be kept in mind when combining chronic SSRI treatment and learning-based therapies, such as cognitive behavioral therapy.

    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.

    Rising incidence of disseminated and extrapulmonary tuberculosis (TB), especially in immunocompromised hosts and patients with multi-drug-resistant tuberculosis, has resulted in an increase of unusual clinical and radiographic presentations of TB. With CT being a common part of emergency room (ER) evaluation of abdominal pain, it is imperative that radiologists be able to recognize abdominal presentations of TB. We discuss and illustrate typical and less common CT manifestations of tuberculosis in the abdomen to help ER radiologists in this task.

    Abdominoplasty is among the most commonly performed aesthetic procedures in plastic surgery. Despite high complication rate, abdominal contouring procedures are expected to rise in popularity with the advent of bariatric surgery. Patients with a history of gastric bypass surgery have an elevated incidence of small bowel obstruction from internal herniation, which is associated with non-specific upper abdominal pain, nausea, and a decrease in appetite. Internal hernias, when subjected to elevated intra-abdominal pressures, have a high-risk of developing ischemic bowel. We present a case report of patient with previous laparoscopic Roux-en-y gastric bypass who developed acute ischemic bowel leading to abdominal compartment syndrome following abdominoplasty. To the best of our knowledge, this is the first reported case in the literature. We herein emphasise on the subtle symptoms and signs that warrant further investigations in prospective patients for an abdominal contouring procedure with a prior history of gastric bypass surgery.

    2008-11-01

    Although the Heimlich maneuver is considered the best intervention for relieving acute upper airway obstruction, several complications have been reported in the literature. These complications can occur as a result of an increase in abdominal pressure leading to a variety of well-documented visceral injuries, including the great vessels. Acute abdominal aortic thrombosis after the Heimlich maneuver is a rare but recognized event; however, to date no case of traumatic dissection and rupture of the abdominal aorta has been described. We report the first known case, to our knowledge, of a traumatic dissection and rupture of the abdominal aorta after a forcefully applied Heimlich maneuver.

    Pyometra is an uncommon and potentially lethal disease that occurs mainly in postmenopausal women. Spontaneous perforation of pyometra presenting as acute abdomen is an extremely rare complication of pyometra, and the patients are always admitted to the emergency department. An additional case is reported herein. In addition, a literature review was performed between 1949 and 2015. A correct preoperative diagnosis was made in 21.05% of all the cases. Of all cases, 25.71% were associated with malignant disease. The mortality rate of spontaneous perforation of pyometra is 31.88%. Thus, it should be considered in the differential diagnosis of acute abdomen in elderly women. Total hysterectomy along with bilateral salpingo-oophorectomy is the preferred treatment. Administration of broad-spectrum antibiotics and postoperative intensive care support are essential to reduce the high mortality.

A 39-year-old patient with descending colon, high-grade adenocarcinoma and coexisting liver and lymph node metastases received two courses of chemotherapy. The patient developed sudden acute abdominal symptoms accompanied by septic shock parameters. The imaging findings on computed tomography were characteristic for abdominal gas gangrene, involving liver metastases, portal vein and lymph nodes with associated pneumoperitoneum. The patient succumbed to the disease within hours following the onset of symptoms.

    We report 2 cases of necrotizing fasciitis of the perineum, perianal area, and male genitalia (Fournier's gangrene) that arose secondary to intra-abdominal infectious processes (ruptured appendicitis and diverticulitis). Management consisted of immediate debridement of necrotic tissue, exploratory laparotomy, and diverting colostomy. The presence of an acute abdominal process was not immediately evident on initial evaluation of either patient. This demonstrates the critical importance of considering intra-abdominal infection in patients with Fournier's gangrene when the more commonly seen urinary tract, perirectal, and traumatic causes are not readily apparent.

    There is a growing request for measuring intra-abdominal pressure in critically ill patients with acute abdominal pain to be clarified. Summarizing the research results on measurement of vesical intra-abdominal pressure and analyzing the level of evidence were the purposes of this integrative literature review, carried out based on the databases LILACS, MEDLINE and PubMed, from 2005 to July 2012. Twenty articles were identified, in that, 12 literature reviews, 4 descriptive and exploratory studies, 2 expert opinions, one prospective cohort study and one was an experience report. The vesical intra-abdominal pressure measurement was considered gold standard. There are variations in the technique however, but some common points were identified: complete supine position, in absence of abdominal contracture, in the end of expiration and expressed in mmHg. Most research results indicate keeping the transducer zeroed at the level of the mid-axillary line at the iliac crest level, and instill 25mL of sterile saline. Strong evidence must be developed.

  20. [Intraabdominal hypertension and abdominal compartment syndrome].

    PubMed

    Sonne, Morten; Hillingsø, Jens

    2008-02-11

    Intraabdominal hypertension (IAH) and abdominal compartment syndrome (ACS) are rare conditions with high mortality. IAH is an intraabdominal pressure (IAP) above 12 mmHg and ACS an IAP above 20 mmHg with evidence of organ dysfunction. IAP is measured indirectly via the bladder or stomach. Various medical and surgical conditions increase the intraabdominal volume. When the content exceeds the compliance of the abdominal wall, the IAP rises. Increased IAP affects the functioning of the brain, lungs, circulation, kidneys, and bowel. The treatment of ACS is a reduction of IAP.

    Background Secondary increase in intra-abdominal pressure (IAP) may result from extra-abdominal pathology, such as massive fluid resuscitation, capillary leak or sepsis. All these conditions increase the extravascular water content. The aim of this study was to analyze the relationship between IAP and body water volume. Material and Methods Adult patients treated for sepsis or septic shock with acute kidney injury (AKI) and patients undergoing elective pharyngolaryngeal or orthopedic surgery were enrolled. IAP was measured in the urinary bladder. Total body water (TBW), extracellular water content (ECW) and volume excess (VE) were measured by whole body bioimpedance. Among critically ill patients, all parameters were analyzed over three consecutive days, and parameters were evaluated perioperatively in surgical patients. Results One hundred twenty patients were studied. Taken together, the correlations between IAP and VE, TBW, and ECW were measured at 408 time points. In all participants, IAP strongly correlated with ECW and VE. In critically ill patients, IAP correlated with ECW and VE. In surgical patients, IAP correlated with ECW and TBW. IAP strongly correlated with ECW and VE in the mixed population. IAP also correlated with VE in critically ill patients. ROC curve analysis showed that ECW and VE might be discriminative parameters of risk for increased IAP. Conclusion IAP strongly correlates with ECW. PMID:25849102

    Inflammatory abdominal aortic aneurysm (IAAA) is a distinct clinicopathological entity, characterized by: (1) clinical presentation, such as back pain, weight loss, and increased ESR, (2) patchy and/or diffuse lymphoplasmacytic infiltration, and (3) marked periaortic fibrosis resulting in thickening of the aneurysmal wall and occasional retroperitoneal fibrosis. Its pathogenesis is unknown, but some authors support the theory that IAAA is a subtype of atherosclerotic abdominal aortic aneurysm because of close relationship between IAAA and atherosclerotic change. In this article, we describe clinical and histological features of IAAA on the basis of the literature and our review of 6 cases of IAAA, emphasizing the similarity and difference between IAAA and atherosclerotic abdominal aortic aneurysm. Our review supports that marked lamellar fibrosis completely replacing the media and adventitia, patchy lymphocytic infiltration (mostly B cells) and endarteritis obliterans are characteristic features of IAAA.

    2008-01-01

    Abstract Recent advances in transplantation, oncology and AIDS therapy have greatly increased life expectancies of patients diagnosed with malignancy, auto-immune disorders and organ failure. However, as this immune compromised population grows, complications of such therapies have become a major source of morbidity and mortality. Classical clinical and laboratory evidence of intra-abdominal pathology may be absent in the immune compromised host. Consequently, the radiologist is increasingly called upon to diagnose acute intra-abdominal complications associated with immunodeficiency. This review explores the aetiology of the acute abdomen in the immune compromised host. The typical radiological appearances of the commonest conditions are illustrated. The challenges and limitations in the radiological diagnosis of these conditions are discussed. PMID:18442955

    Summary Background Wandering spleen is a rare condition which if uncorrected, can result in torsion and infarction. Clinical presentation of a wandering spleen can vary from asymptomatic abdominal mass to acute abdominal pain. Radiological investigations play a pivotal role in diagnosis as the clinical diagnosis is usually impossible. Case Report We present a case of wandering spleen with torsion and complete infarction that occurred in a 32-year-old multiparous female. The diagnosis was established preoperatively on colour Doppler and CT of the abdomen with subsequent confirmation on surgery. Conclusions Wandering spleen is a rare clinical condition which can present as acute abdomen. An increased awareness of this entity together with the timely use of ultrasound and CT of the abdomen can play an important role in preoperative diagnosis and surgical management. PMID:27057261

    Current conditioning regimens provide insufficient disease control in relapsed/refractory acute leukemia patients undergoing hematopoietic stem cell transplantation (HSCT) with active disease. Intensification of chemotherapy and/or total body irradiation (TBI) is not feasible because of excessive toxicity. Total marrow and lymphoid irradiation (TMLI) allows for precise delivery and increased intensity treatment via sculpting radiation to sites with high disease burden or high risk for disease involvement, while sparing normal tissue. We conducted a phase I trial in 51 patients (age range, 16 to 57 years) with relapsed/refractory acute leukemia undergoing HSCT (matched related, matched unrelated, or 1-allele mismatched unrelated) with active disease, combining escalating doses of TMLI (range, 1200 to 2000 cGy) with cyclophosphamide (CY) and etoposide (VP16). The maximum tolerated dose was declared at 2000 cGy, as TMLI simulation studies indicated that >2000 cGy might deliver doses toxic for normal organs at or exceeding those delivered by standard TBI. The post-transplantation nonrelapse mortality (NRM) rate was only 3.9% (95% confidence interval [CI], .7 to 12.0) at day +100 and 8.1% (95% CI, 2.5 to 18.0) at 1 year. The cumulative incidence of grades II to IV acute graft-versus-host disease (GVHD) was 43.1% (95% CI, 29.2 to 56.3) and for grade III and IV, it was 13.7% (95% CI, 6.9 to 27.3). The day +30 complete remission rate for all patients was 88% and was 100% for those treated at 2000 cGy. The overall 1-year survival was 55.5% (95% CI, 40.7 to 68.1). The TMLI/CY/VP16 conditioning regimen is well tolerated at TMLI doses up to 2000 cGy with a low 100-day and 1-year NRM rate and no increased risk of GVHD with higher doses of radiation.

    Stressful experiences modify activity in areas of the brain involved in the rewarding effects of psychostimulants. In the present study we evaluated the influence of acute social defeat (ASD) on the conditioned rewarding effects of cocaine in adolescent (PND 29-32) and adult (PND 50-53) male mice in the conditioned place preference (CPP) paradigm. Experimental mice were exposed to social defeat in an agonistic encounter before each session of conditioning with 1mg/kg or 25mg/kg of cocaine. The effects of social defeat on corticosterone levels were also evaluated. Adult mice exposed to ASD showed an increase in the conditioned reinforcing effects of cocaine. Only these mice developed cocaine-induced CPP with the subthreshold dose of cocaine, and they needed a higher number of extinction sessions for the 25mg/kg cocaine-induced CPP to be extinguished. In adolescent mice, on the other hand, ASD reduced the conditioned reinforcing effects of cocaine, since CPP was not produced with the lower dose of cocaine and was extinguished faster when they were conditioned with 25mg/kg. Adult mice exposed to social defeat displayed higher levels of corticosterone than their controls and adolescent mice. Our results confirm that the effect of social defeat stress on the acquisition and reinstatement of the CPP induced by cocaine varies depending on the age at which this stress is experienced.

The most important finding was a tuboovarialabscess at the left pelvic side with involvement of the serosa of the jejunum, ileum, sigma, and omentum majus. Intraoperative exploration showed a solid retroperitoneal infiltration between the pelvic side wall and sigma. Another infiltration was found on the left side of the abdominal wall. The diagnosis was confirmed by histopathological examination and the patient was treated by a combination of Aminopenicillin and Metronidazol. After a period of three months we observed a complete regression of the clinical and the MRI findings.

    2004-01-01

    The prune belly syndrome (OMIM 100100) is an association of bladder dilation with hypoplasia of the abdominal wall muscles. This malformation sequence is due to early urethral obstruction. We report a family with abdominal wall muscular hypoplasia as an isolated defect, not associated with the urethral obstruction sequence. The proband is a q3-year-old male who presented with abdominal wall laxity and severe constipation. His mother, maternal grandmother and younger brother had varying degrees of abdominal wall muscular deficiency and constipation. His mother's condition was aggravated by her 2 pregnancies. This family shows vertical transmission (compatible with autosomal dominant or mitochondrial inheritance) of the abdominal phenotype of prune belly sequence without any evidence of urinary tract or renal pathology. The expression in the sons may remain incomplete because abdominal distention due to pregnancy will not occur.

    Stensby, J Derek; Baker, Jonathan C; Fox, Michael G

    2016-02-01

    The lateral abdominal wall is comprised of three muscles, each with a different function and orientation. The transversus abdominus, internal oblique, and external oblique muscles span the abdominal cavity between the iliocostalis lumborum and quadratus lumborum posteriorly and the rectus abdominis anteriorly. The lateral abdominal wall is bound superiorly by the lower ribs and costal cartilages and inferiorly by the iliac crest and inguinal ligament. The lateral abdominal wall may be acutely or chronically injured in a variety of athletic endeavors, with occasional acute injuries in the setting of high-energy trauma such as motor vehicle collisions. Injuries to the lateral abdominal wall may result in lumbar hernia formation, unique for its high incarceration rate, and also Spigelian hernias. This article will review the anatomy, the magnetic resonance (MR) imaging approach, and the features and complications of lateral abdominal wall injuries.

    A gnotobiotic isolation system based on those developed in veterinary research has been constructed for hospital use. Fifteen patients with leukaemia and neutropenia spent a total of 110 weeks in plastic isolators, and none acquired any infection. Endogenous flora was effectively suppressed by topical antiseptics and gastrointestinal decontamination effected with nonabsorbable antibiotics. The isolator system was acceptable to patients and staff and much cheaper than the use of sterile rooms. Other advantages of the system are portability, easy storage, and use on ordinary open wards without prejudice to the microbiological protection afforded. It is as yet uncertain whether protective environments of this type will substantially improve the outcome of treatment for the acute leukaemias. PMID:1203666

    2016-04-01

    Acute kidney injury (AKI) is a common complication associated with high morbidity and mortality in hospitalized patients. One potential mechanism underlying renal injury is ischaemia/reperfusion injury (IRI), which attributed the organ damage to the inflammatory and oxidative stress responses induced by a period of renal ischaemia and subsequent reperfusion. Therapeutic strategies that aim at minimizing the effect of IRI on the kidneys may prevent AKI and improve clinical outcomes significantly. In this review, we examine the technique of remote ischaemic preconditioning (rIPC), which has been shown by several trials to confer organ protection by applying transient, brief episodes of ischaemia at a distant site before a larger ischaemic insult. We provide an overview of the current clinical evidence regarding the renoprotective effect of rIPC in the key clinical settings of cardiac or vascular surgery, contrast-induced AKI, pre-existing chronic kidney disease (CKD) and renal transplantation, and discuss key areas for future research.

    Even though exercise hemorheology at hypoxic condition has been considered as a good tool to understand clinical hemorheology, there have been limited studies reported. Previous researches showed that hemorheological variables are closely correlated with oxygen delivery capacity during exercise. The present study investigated hypoxic responses including RBC deformability and aggregation, metabolic parameters and complete blood cell counts at various hypoxic conditions during cycling exercise and recovery. Eleven Korean healthy male subjects performed submaximal bike exercise at sea level (20.9% O2) and under various hypoxic conditions (16.5% O2, 14.5% O2, 12.8% O2, and 11.2% O2) in a random order. The submaximal bike exercise intensity of the subjects was 70% maximum heart rate at sea level. All variables were measured at rest, during exercise and recovery 30-minute, respectively. As oxygen partial pressure decreased, arterial blood oxygen saturation decreased but oxygen uptake did not change much. Heart rate and lactate concentration during exercise increased when oxygen partial pressure is less than or equal to 14.5% O2 condition. Red blood cell (RBC) counts, hemoglobin counts, and hematocrit level were not apparently altered with hypoxic conditions. RBC deformability showed significant alterations at 11.2% O2 conditions compared with other hypoxic conditions during exercise or recovery, except at 10 minutes recovery. However, decreases in oxygen partial pressure did not affect red blood cell aggregation. Therefore, we conclude that alterations in RBC deformability may reduce aerobic capabilities at hypoxic condition.

    Strongyloides stercolaris infestation is rather rare in Iraq. Individuals with infection confined to the intestinal tract are often asymptomatic. Symptoms include abdominal pain, diarrhea, weight loss and other non-specific complaints. The diagnosis depends upon repeated examination of stool and duodenal aspirate. Two cases presenting as sub-acute intestinal obstruction and mimicking primary intestinal lymphoma (PIL) on presentation are presented. Differentiation between the two conditions regarding presenting features, barium studies and pathology are discussed.

    Little information is available about the development of abdominal abscesses in adolescents with Crohn's disease. We report the clinical presentation of five adolescents with Crohn's disease who developed this complication. The mean time from diagnosis until development of an abdominal abscess was 1.7 years. The admitting diagnosis was an acute abdomen in two patients and recurrent Crohn's disease in the other three. No features of the clinical presentation or laboratory data distinguished this group from other adolescents with Crohn's disease. The use of ultrasound and CT scanning was helpful in making this diagnosis preoperatively. Those patients with active Crohn's disease who do not respond promptly to medical therapy should be evaluated for the development of this complication.

In order to improve such patients’ outcome, we conducted a phase 2, prospective, multicenter trial to test the feasibility of a new sequential regimen, combining a short course of intensive chemotherapy and a reduced intensity-conditioning regimen, before allogeneic stem-cell transplantation. Twenty-four patients (median age, 47 years) with acute myeloid leukemia in primary treatment failure were included. Cytogenetic risk was poor in 15 patients (62%) and intermediate in nine (38%). The sequential regimen consisted of clofarabine (30 mg/m2/day) and cytosine arabinoside (1 g/m2/day) for 5 days, followed, after a 3-day rest, by reduced-intensity conditioning and allogeneic stem-cell transplantation combining cyclophosphamide (60 mg/kg), intravenous busulfan (3.2 mg/kg/day) for 2 days and anti-thymocyte globulin (2.5 mg/kg/day) for 2 days. Patients in complete remission at day +120 received prophylactic donor lymphocyte infusion. Eighteen patients (75%) achieved complete remission. With a median follow-up of 24.6 months, the Kaplan-Meier estimate of overall survival was 54% (95% CI: 33–71) at 1 year and 38% (95% CI: 18–46) at 2 years. The Kaplan-Meier estimate of leukemia-free survival was 46% (95% CI: 26–64) at 1 year and 29% (95% CI: 13–48) at 2 years. The cumulative incidence of non-relapse mortality was 8% (95% CI: 1–24) at 1 year and 12% (95% CI: 3–19) at 2 years. Results from this phase 2 prospective multicenter trial endorsed the safety and efficacy of a clofarabine-based sequential reduced-toxicity conditioning regimen, which warrants further investigation.

    The spatial and temporal changes of weather factors depend on geographical location, seasons and the time of the day. Our study examines the relationships of meteorological factors and the incidence of acute myocardial infarction (AMI). A retrospective analysis of patients diagnosed with AMI between 2000 and 2004 in Hungary (n = 81,956 patients) was carried out. Data were collected by the National Health Insurance Fund Administration (OEP) and the National Meteorology Service (OMSZ). A peak period of the occurrence of AMI was found during spring, while minimum number of events were recorded during summer. Significant difference was observed between the number of events each season (F = 34.741; p < 0.001; N = 81,956). A medium level negative correlation was found between the monthly average temperature and the occurrence of AMI (r = -0.404) during the period examined. A positive correlation was shown between front movements and the number of events per season (r = 0.053). Average barometric pressure changes, the number of front movements and the number of AMI events also showed a nearly similar seasonal deviation. Our findings show that certain meteorological factors may be related to the onset of AMI, however other factors also play an important role.

    Recent advances in neuronal culturing techniques have supplied a new set of tools for studying neural tissue, providing effective means to study molecular aspects of regulatory elements in the supraoptic nucleus of the hypothalamus (SON). To combine molecular biology techniques with electrophysiological recording, we modified an organotypic culture protocol to permit transfection and whole cell patch-clamp recordings from SON cells. Neonatal mouse brain coronal sections containing the SON were dissected out, placed on a filter insert in culture medium, and incubated for at least 4 days to allow attachment to the insert. The SON was identifiable using gross anatomical landmarks, which remained intact throughout the culturing period. Immunohistochemical staining identified both vasopressinergic and oxytocinergic cells present in the cultures, typically appearing in well-defined clusters. Whole cell recordings from these cultures demonstrated that certain properties of the neonatal mouse SON were comparable to adult mouse magnocellular neurons. SON neurons in both neonatal cultures and acute adult slices showed similar sustained outward rectification above -60 mV and action potential broadening during evoked activity. Membrane potential, input resistance, and rapidly inactivating potassium current density (IA) were reduced in the cultures, whereas whole cell capacitance and spontaneous synaptic excitation were increased, perhaps reflecting developmental changes in cell physiology that warrant further study. The use of the outlined organotypic culturing procedures will allow the study of such electrophysiological properties of mouse SON using whole cell patch-clamp, in addition to various molecular, techniques that require longer incubation times.

    The present study aimed to analyze and compare the effects of classical and remote ischemic postconditioning (POC) on rat renal ischemia/reperfusion (IR)-induced acute kidney injury. After right nephrectomy, male rats were randomly assigned into four groups (n = 8). In the IR group, 45 min of left renal artery occlusion was induced followed by 24 h of reperfusion. In the classical POC group, after induction of 45 min ischemia, 4 cycles of 10 s of intermittent ischemia and reperfusion were applied to the kidney before complete restoring of renal blood. In the remote POC group, 4 cycles of 5 min ischemia and reperfusion of left femoral artery were applied after 45 min renal ischemia and right at the time of renal reperfusion. There was a reduction in renal function (increase in blood urea and creatinine) in the IR group. Application of both forms of POC prevented the IR-induced reduction in renal function and histology. There were also significant improvements in kidney oxidative stress status in both POC groups demonstrated by a reduction in malondialdehyde (MDA) formation and preservation of antioxidant levels comparing to the IR group. We concluded that both methods of POC have protective effects on renal function and histology possibly by a reduction in IR-induced oxidative stress.

    This was a cross-sectional study within Brazil's Project for the Expansion and Consolidation of Family Health, 2005, with the objective of universal and free access to the medication prescribed in the last medical appointment for acute health problems and to estimate the degree to which access may have improved with inclusion of the medicines in prevailing policies and programs. The sample included 4,060 adults living in the area of primary health care units in 41 municipalities in South and Northeast Brazil. Access was greater in the South (83.2%) than in the Northeast (71%), and free access was similar (37%), with a greater share by the Family Health Program (FHP) when compared to the traditional model, especially in the Northeast. Some 60% of prescribed medicines and 50% of those on the National List of Essential Medicines (RENAME) were paid for. No variation was observed in the proportion of medicines present on the prevailing RENAME list and access. However, 40% of the medicines that were paid for can currently be obtained through the Popular Pharmacy Program. The latter program appears to emerge as a new way to guarantee access to medicines prescribed in the health system.

    Diagnostic imaging is often not indicated in chronic abdominal pain. In particular, undifferentiated abdominal pain is rarely an indication for a CT scan. CT scanning is overused even when imaging is required. Other modalities may be preferable. A normal CT scan does not rule out cancer. Alarm symptoms, including anaemia, blood in the stool, waking at night with gastrointestinal symptoms, and weight loss, should be investigated. The most appropriate modality depends on the symptoms. Clinical information on request forms for CT scans should be specific and include the suspected condition as this helps the radiologist to determine an appropriate imaging protocol.

    Penetrating abdominal wounds are frequent and serious. 330 cases have been treated in the Department of Emergencies and visceral Surgery at Averroes Hospital of Casablanca from 1980 to 1990. The predominance of male sex is noted, and these wounds are always the result of aggression by white arm. All patients have been operated, the white laparotomy rate is of 36%. The classic interventionist attitude is still recommended in spite of this high rate, because our present conditions can't permit us a rigorous watching. According to abdominal lesions, the different interventions are reviewed, and their indications are detailed.

    Psychostimulant-induced locomotor sensitization and disrupted latent inhibition (LI) of a classically conditioned association are two paradigms that have been widely studied as animal behavioural models of psychosis. In this study we assessed the effects of withdrawal from the repeated intermittent administration of cocaine on LI of a conditioned fear response. Animals which were either preexposed (PE) to a tone conditioned stimulus (CS) or naive to the tone (i.e. non-preexposed: NPE) subsequently experienced 10 pairings of the tone CS with footshock. Afterwards, both groups received five daily injections of cocaine (20 mg/kg, i.p.) or saline. After 3 days of withdrawal from drug treatment, animals were tested for conditioned freezing to the context of the footshock chamber, and 1 day later, for conditioned freezing to the tone CS. Cocaine-sensitized animals exhibited markedly enhanced LI compared to saline-treated animals, due to the fact that NPE-cocaine animals spent more time freezing during the tone CS than NPE-saline animals, whereas PE-cocaine animals showed a tendency toward reduced freezing compared to the saline groups. While these results suggest the presence of increased anxiety in cocaine-withdrawn NPE animals, the absence of this effect in cocaine-withdrawn PE rats indicates that cocaine withdrawal also influences the retrieval of previously learned information.

    The prevalence of prasugrel contraindications and specific conditions requiring precaution for its use in a real world acute coronary syndrome (ACS) population is not known. We performed a prospective descriptive study in 1016 consecutive moderate to high risk ACS patients. In 646 patients (63.6%) subjected to percutaneous coronary intervention, analysis of absolute contraindications (history of stroke/transient ischemic attack or active bleeding), relative contraindications and specific conditions (age ≥ 75 years and/or weight < 60 kg) for prasugrel theoretical administration was performed. In 242 (37.5%) patients there was at least one absolute or relative contraindication or specific condition requiring attention for its use. Overall, 23.1% of patients in our cohort had a prior stroke/transient ischemic attack and/or specific condition to be considered for prasugrel administration. Specifically, the prevalence of stroke/TIA was 3.6%, the prevalence of patients ≥75 years 20% and the prevalence of patients weighing <60 kg 2.2%. Among patients ≥75 years old, 63 (9.8%) had diabetes mellitus or previous myocardial infarction, consisting a high risk subgroup that might benefit from prasugrel administration. In a real world ACS population a relatively high proportion of patients have a potential contraindication for prasugrel administration or necessitate special attention for its use.

    Abdominal and thoracic surgical procedures can result in significant acute postoperative pain. Present evidence shows that postoperative pain management remains inadequate especially after "minor" surgical procedures. Various therapeutic options including regional anesthesia techniques and systemic pharmacotherapy are available for effective treatment of postoperative pain. This work summarizes the pathophysiological background of postoperative pain after abdominal and thoracic surgery and discusses the indication, effectiveness, risks, and benefits of the different therapeutic options. Special focus is given to the controversial debate about the indication for epidural analgesia, as well as various alternative therapeutic options, including transversus abdominis plane (TAP) block, paravertebral block (PVB), wound infiltration with local anesthetics, and intravenous lidocaine. In additional, indications and contraindications of nonopioid analgesics after abdominal and thoracic surgery are discussed and recommendations based on scientific evidence and individual risk and benefit analysis are made. All therapeutic options discussed are eligible for clinical use and may contribute to improve postoperative pain outcome after abdominal and thoracic surgical procedures.

    Following previous research on human tissue in conditions of acute and massive hypoxia, in the present work the authors compared the cellular enzymic response to oxidative stress in normoxic (perifocal) and hypoxic (focal) areas in human brain affected by regional acute vasculopathies. Two homogeneous groups of patients were selected following strict clinical inclusion/exclusion criteria. The groups of patients were treated with a placebo or acetyl-carnitine at same doses and following randomized, double-blind procedures. The focal areas showed a significant functional damage in lactate, pyruvate and succinate dehydrogenases and in the cytochrome oxidase activity when compared with the enzymic capacities of perifocal areas (normoxic as controls). The pretreatment with acetyl-carnitine antagonized the above-mentioned enzymic damage by a protective action linked to the endocellular energy restoration. In accordance with these data, the therapeutic role played by acetyl-carnitine in the cerebral focal hypoxia appeared to be a determinant for the cell survival mainly in the reversible phase of oxidative damage.

    Introduction Abdominal organ injury in a primary blast type is always challenging for diagnosis. Air containing abdominal viscera is most vulnerable to effects of primary blast injury. In any patient exposed to a primary blast wave who presents with an acute abdomen, an abdominal organ injury is to be kept in a clinical suspicion. Aim Study various abdominal organ injuries occurring in a primary type of blast injury. Material and methods: All those who had exploratory laparotomy for abdominal organ injuries after a primary blast injury for a period of 10 years from January 1998 - January 2008 were included in this retrospective study. Results Total 154 patients had laparotomy for abdominal organ injuries with a primary blast type of injury. Small intestine was damaged in 48 patients (31.1%) followed by spleen in 22.7% cases. 54 patients (35.06%) had more than one organ injured. Liver laceration was present in 30 patients (19.48%). Multiple small gut perforations were present in 37 patients (77.08%). Negative laparotomy was found in 5 patients (3.24%) whereas 3 (1.94%) had re-exploration. Mortality was present in 6 patients (3.89%). Conclusions Primary blast injury causes varied abdominal organ injuries. Single or multiple organ damage can be there. Small intestine is commonest viscera injured. Laparotomy gives final diagnosis. PMID:20025766

  11. Acute exposure to selenium disrupts associative conditioning and long-term memory recall in honey bees (Apis mellifera).

    A plethora of toxic compounds - including pesticides, heavy metals, and metalloids - have been detected in honey bees (Apis mellifera) and their colonies. One such compound is selenium, which bees are exposed to by consuming nectar and pollen from flowers grown in contaminated areas. Though selenium is lethal at high concentrations, sublethal exposure may also impair honey bees' ability to function normally. Examining the effect of selenium exposure on learning and memory provides a sensitive assay with which to identify sublethal effects on honey bee health and behavior. To determine whether sublethal selenium exposure causes learning and memory deficits, we used proboscis extension reflex conditioning coupled with recall tests 30min and 24h post-conditioning. We exposed forager honey bees to a single sublethal dose of selenium, and 3h later we used an olfactory conditioning assay to train the bees to discriminate between one odor associated with sucrose-reinforcement and a second unreinforced odor. Following conditioning we tested short- and long-term recall of the task. Acute exposure to as little as 1.8ng of an inorganic form of selenium (sodium selenate) before conditioning caused a reduction in behavioral performance during conditioning. And, exposure to 18ng of either an inorganic form (sodium selenate) or an organic form (methylseleno-l-cysteine) of selenium caused a reduction in the bees' performance during the long-term recall test. These concentrations of selenium are lower than those found in the nectar of plants grown in selenium-contaminated soil, indicating that even low-grade selenium toxicity produces significant learning and memory impairments. This may reduce foragers' ability to effectively gather resources for the colony or nurse bees' ability to care for and maintain a healthy colony.

    D-cycloserine, the glutamate N-methyl-D-aspartate receptor partial agonist, has been reported to facilitate the extinction of learned fears acquired in both naturalistic and laboratory settings. The current study extended this literature by evaluating the ability of either chronic or acute administrations of DCS to modulate the extinction and spontaneous recovery of a conditioned taste aversion (CTA). Twenty-three hour fluid-deprived Sprague-Dawley rats acquired a strong CTA following 3 pairings of a conditioned stimulus (CS; 0.3% oral saccharin)+unconditioned stimulus [US; 81 mg/kg (i.p.) lithium chloride (LiCl)]. In separate groups of rats, we then employed 2 different extinction paradigms: (1) CS-only (CSO-EXT) in which saccharin was presented every-other day, or (2) Explicitly Unpaired (EU-EXT) in which both saccharin and LiCl were presented but on alternate days. Previous studies have indicated that the EU-EXT procedure speeds up the extinction process. Further, spontaneous recovery of a CTA emerges following CSO-EXT but the EU-EXT paradigm causes a suppression of spontaneous recovery. DCS (15 mg/kg, i.p.) was administered immediately after daily liquid presentations (saccharin or water, alternate days) during the extinction period. In an acute drug manipulation, DCS (15 mg/kg, i.p.) or saline control injections were administered for 4 days only. This was done during one of 3 different phases of extinction [i.e., static (2-5%), early dynamic (8-16%), or middle dynamic (20-40%) saccharin reacceptance]. Other animals assigned to the chronic DCS condition received daily DCS (15 mg/kg, i.p.) throughout extinction. Changes in saccharin drinking in these animals were compared to the data from rats that received no drug (saline controls). Once rats met our criterion for asymptotic extinction (90% reacceptance of the CS) they entered a 30-day latency period during which they received water for 1 h/day. The day after the completion of the latency period, a final

    Antibodies to the pan-leukocyte adhesion-GPCR CD97 efficiently block neutrophil recruitment in mice, thereby reducing antibacterial host defense, inflammatory disease, and hematopoietic stem cell mobilization. Here, we investigated the working mechanism of the CD97 antibody 1B2. Applying sterile models of inflammation, intravital microscopy, and mice deficient for the CD97L CD55, the complement component C3, or the FcR common γ-chain, we show that 1B2 acts in vivo independent of ligand-binding interference by depleting PMN granulocytes in bone marrow and blood. Granulocyte depletion with 1B2 involved FcR but not complement activation and was associated with increased serum levels of TNF and other proinflammatory cytokines. Notably, depletion of granulocytes by CD97 antibody required acute inflammation, suggesting a mechanism of conditional, antibody-mediated granulocytopenia.

    Postoperative acute cholecystitis is a rare complication of orthopaedic surgery and is unrelated to the biliary tract. In particular, in the case of immediate postoperative state after surgery such as kyphoplasty at the thoracic vertebra, symptoms related to inflammation mimic those of abdominal origin, so the diagnosis and the treatment of acute cholecystitis can be delayed leading to a fatal outcome. It is important that physicians should be aware of the postoperative patient's condition in order to make an early diagnosis and determine treatment. PMID:23060986

    Although acute appendicitis is the most frequent cause of the acute abdomen in the United States, its accurate diagnosis in reproductive-age women remains difficult. Problems in making the diagnosis are evidenced by negative appendectomy rates in this group of 20 per cent to 45 per cent. Abdominal CT scanning has been used in diagnosing acute appendicitis, but its reliability and usefulness remains controversial. There is concern that the use of CT scanning to make this diagnosis leads to increased and unwarranted healthcare charges and costs. The purpose of our study is to determine if abdominal CT scanning is an effective test in making the diagnosis of acute appendicitis in reproductive-age women (age, 16-49 years) with right lower quadrant abdominal pain and to determine if its use is cost-effective. From January 2003 to December 2006, 439 patients were identified from our academic surgical database and confirmed by chart review as undergoing an appendectomy with a pre- or postoperative diagnosis of acute appendicitis. Data, including age, presence and results of preoperative abdominal CT scans, operative findings, and pathology reports were reviewed. Comparison of patients receiving a preoperative CT scan with those who did not was performed using chi-squared analysis. In the subgroup of reproductive-age women, there was a significant difference in negative appendectomy rates of 17 per cent in the group that received abdominal CT scans versus 42 per cent in the group that did not (P < 0.038). After accounting for the patient and insurance company costs, abdominal CT scan savings averaged $1412 per patient. Abdominal CT scanning is a reliable, useful, and cost-effective test for evaluating right lower quadrant abdominal pain and making the diagnosis of acute appendicitis in reproductive-age women.

    Mechanical obstruction by hematocolpos can result in acute urinary retention.(1) Imperforate hymen is a rare condition that presents mainly with primary amenorrhea, cyclic abdominal pain and rarely, urine retention in pubertal girls.(2) This is a 23-year old female who presented with acute urine retention. She had history of previous vaginal repair of imperforate hymen. On examination patient was found to have imperforate hymen. After fixing a catheter, an US scan showed hematocolpos that was confirmed CT. She was eventually underwent hymenectomy. We conclude that in peripubertal female with acute urinary retention, hematocolpos should be considered.

    Blood in the splanchnic vasculature can be transferred to the extremities. We quantified such blood shifts in normal subjects by measuring trunk volume by optoelectronic plethysmography, simultaneously with changes in body volume by whole body plethysmography during contractions of the diaphragm and abdominal muscles. Trunk volume changes with blood shifts, but body volume does not so that the blood volume shifted between trunk and extremities (Vbs) is the difference between changes in trunk and body volume. This is so because both trunk and body volume change identically with breathing and gas expansion or compression. During tidal breathing Vbs was 50–75 ml with an ejection fraction of 4–6% and an output of 750–1500 ml/min. Step increases in abdominal pressure resulted in rapid emptying presumably from the liver with a time constant of 0.61±0.1SE sec. followed by slower flow from non-hepatic viscera. The filling time constant was 0.57±0.09SE sec. Splanchnic emptying shifted up to 650 ml blood. With emptying, the increased hepatic vein flow increases the blood pressure at its entry into the inferior vena cava (IVC) and abolishes the pressure gradient producing flow between the femoral vein and the IVC inducing blood pooling in the legs. The findings are important for exercise because the larger the Vbs the greater the perfusion of locomotor muscles. During asystolic cardiac arrest we calculate that appropriate timing of abdominal compression could produce an output of 6 L/min. so that the abdominal circulatory pump might act as an auxiliary heart.

    Lateral abdominal wall (LAW) defects can manifest as a flank hernias, myofascial laxity/bulges, or full-thickness defects. These defects are quite different from those in the anterior abdominal wall defects and the complexity and limited surgical options make repairing the LAW a challenge for the reconstructive surgeon. LAW reconstruction requires an understanding of the anatomy, physiologic forces, and the impact of deinnervation injury to design and perform successful reconstructions of hernia, bulge, and full-thickness defects. Reconstructive strategies must be tailored to address the inguinal ligament, retroperitoneum, chest wall, and diaphragm. Operative technique must focus on stabilization of the LAW to nonyielding points of fixation at the anatomic borders of the LAW far beyond the musculofascial borders of the defect itself. Thus, hernias, bulges, and full-thickness defects are approached in a similar fashion. Mesh reinforcement is uniformly required in lateral abdominal wall reconstruction. Inlay mesh placement with overlying myofascial coverage is preferred as a first-line option as is the case in anterior abdominal wall reconstruction. However, interposition bridging repairs are often performed as the surrounding myofascial tissue precludes a dual layered closure. The decision to place bioprosthetic or prosthetic mesh depends on surgeon preference, patient comorbidities, and clinical factors of the repair. Regardless of mesh type, the overlying soft tissue must provide stable cutaneous coverage and obliteration of dead space. In cases where the fasciocutaneous flaps surrounding the defect are inadequate for closure, regional pedicled flaps or free flaps are recruited to achieve stable soft tissue coverage. PMID:23372458

    The impact of pretransplant (hematopoietic cell transplantation [HCT]) cytarabine consolidation therapy on post-HCT outcomes has yet to be evaluated after reduced-intensity or nonmyeloablative conditioning. We analyzed 604 adults with acute myeloid leukemia in first complete remission (CR1) reported to the Center for International Blood and Marrow Transplant Research who received a reduced-intensity or nonmyeloablative conditioning HCT from an HLA-identical sibling, HLA-matched unrelated donor, or umbilical cord blood donor from 2000 to 2010. We compared transplant outcomes based on exposure to cytarabine postremission consolidation. Three-year survival rates were 36% (95% confidence interval [CI], 29% to 43%) in the no consolidation arm and 42% (95% CI, 37% to 47%) in the cytarabine consolidation arm (P = .16). Disease-free survival was 34% (95% CI, 27% to 41%) and 41% (95% CI, 35% to 46%; P = .15), respectively. Three-year cumulative incidences of relapse were 37% (95% CI, 30% to 44%) and 38% (95% CI, 33% to 43%), respectively (P = .80). Multivariate regression confirmed no effect of consolidation on relapse, disease-free survival, and survival. Before reduced-intensity or nonmyeloablative conditioning HCT, these data suggest pre-HCT consolidation cytarabine does not significantly alter outcomes and support prompt transition to transplant as soon as morphologic CR1 is attained. If HCT is delayed while identifying a donor, our data suggest that consolidation does not increase transplant treatment-related mortality and is reasonable if required.

    Background Identification of acute kidney injury (AKI) can be challenging in patients with underlying chronic disease, and biomarkers often perform poorly in this population. In this study we examined the performance characteristics of the novel biomarker panel of urinary tissue inhibitor of metalloproteinases-2 (TIMP2) and insulin-like growth factor-binding protein 7 ([IGFBP7]) in patients with a variety of comorbid conditions. Methods We analyzed data from two multicenter studies of critically ill patients in which [TIMP2]•[IGFBP7] was validated for prediction of Kidney Disease: Improving Global Outcomes (KDIGO) Stage 2 or 3 AKI within 12 h. We constructed receiver operating characteristic (ROC) curves for AKI prediction both overall and by comorbid conditions common among patients with AKI, including diabetes mellitus, congestive heart failure (CHF) and chronic kidney disease (CKD). Results In the overall cohort of 1131 patients, 139 (12.3%) developed KDIGO Stage 2 or 3 AKI. [TIMP2]•[IGFBP7] was significantly higher in AKI versus non-AKI patients, both overall and within each comorbidity subgroup. The AUC for [TIMP2]•[IGFBP7] in predicting AKI was 0.81 overall. Higher AUC was noted in patients with versus without CHF (0.89 versus 0.79; P = 0.026) and CKD (0.91 versus 0.80; P = 0.024). Conclusions We observed no significant impairment in the performance of cell cycle arrest biomarkers due to the presence of chronic comorbid conditions. PMID:27342582

    Over the past several years, abdominal single photon emission computed tomography (SPECT) imaging has evolved from a research tool to an important clinical imaging modality that is helpful in the diagnostic assessment of a wide variety of disorders involving the abdominal viscera. Although liver-spleen imaging is the most popular of the abdominal SPECT procedures, blood pool imaging is becoming much more widely utilized for the evaluation of cavernous hemangiomas of the liver as well as other vascular abnormalities in the abdomen. Adjunctive indium leukocyte and gallium SPECT studies are also proving to be of value in the assessment of a variety of infectious and neoplastic diseases. As more experience is acquired in this area, SPECT should become the primary imaging modality for both gallium and indium white blood cells in many institutions. Renal SPECT, on the other hand, has only recently been used as a clinical imaging modality for the assessment of such parameters as renal depth and volume. The exact role of renal SPECT as a clinical tool is, therefore, yet to be determined. 79 references.

  3. Functional abdominal pain

    Functional abdominal pain or functional abdominal pain syndrome (FAPS) is an uncommon functional gut disorder characterised by chronic or recurrent abdominal pain attributed to the gut but poorly related to gut function. It is associated with abnormal illness behaviour and patients show psychological morbidity that is often minimised or denied in an attempt to discover an organic cause for symptoms. Thus the conventional biomedical approach to the management of such patients is unhelpful and a person's symptom experience is more usefully investigated using a biopsychosocial evaluation, which necessarily entails a multidisciplinary system of healthcare provision. Currently the pathophysiology of the disorder is poorly understood but is most likely to involve a dysfunction of central pain mechanisms either in terms of attentional bias, for example, hypervigilance or a failure of central pain modulation/inhibition. Although modern neurophysiological investigation of patients is promising and may provide important insights into the pathophysiology of FAPS, current clinical management relies on an effective physician-patient relationship in which limits on clinical investigation are set and achievable treatment goals tailored to the patient's needs are pursued.

    Abstract The use of minimally invasive surgery (MIS) in pediatric patients has been steadily increasing in recent years. However, its use for diagnosing and treating abdominal tumors in children is still limited compared with adults, especially when malignancy is a matter of debate. Here, we describe the experience at our center with pediatric abdominal tumors to show the safety and feasibility of MIS. Based on a retrospective review of patient records, we selected for study those pediatric patients who had undergone diagnostic exploration or curative resection for abdominal tumors at a single center from January 2010 through August 2015. Diagnostic exploration for abdominal tumors was performed in 32 cases and curative resection in 173 cases (205 operations). MIS was performed in 11 cases of diagnostic exploration (34.4%) and 38 cases of curative resection (21.9%). The mean age of the children who underwent MIS was 6.09 ± 5.2 years. With regard to diagnostic exploration, patient characteristics and surgical outcomes were found to be similar for MIS and open surgery. With regard to curative resection, however, the mean age was significantly lower among the patients who underwent open surgery (4.21 ± 4.20 vs 6.02 ± 4.99 for MIS, P = 0.047), and the proportion of malignancies was significantly higher (80% vs 39.4% for MIS, P < 0.001). MIS compared favorably with open surgery with respect to the rate of recurrence (6.7% vs 35.1%, P = 0.035), the rate of intraoperative transfusions (34.2% vs 58.5%, P = 0.01), the median amount of blood transfused (14 vs 22 mL/kg, P = 0.001), and the mean number of hospital days (4.66 ± 2.36 vs 7.21 ± 5.09, P < 0.001). Complication rates did not differ significantly between the MIS and open surgery groups. The operation was converted to open surgery in 3 cases (27.2%) of diagnostic MIS and in 5 cases (13.1%) of curative MIS. MIS was found to be both feasible and effective for the

    Hepatic portal venous gas (HPVG) is induced by various abdominal diseases. Since HPVG is accompanied by bowel ischemia, intestinal infection and hypovolemia, various modes of critical management are needed to treat the underlying conditions. HPVG associated with abdominal complications after surgery has rarely been reported. We present 4 patients with HPVG after abdominal surgery: 2 of the 4 patients died of multiple organ failure, and the other 2 recovered with solely conservative therapy. Although postoperative HPVG is a severe and life-threatening condition, early detection and systemic treatment lead to a better patient outcome. PMID:27403110

  6. Physical activity and abdominal obesity in youth.

    2009-08-01

    Childhood obesity continues to escalate despite considerable efforts to reverse the current trends. Childhood obesity is a leading public health concern because overweight-obese youth suffer from comorbidities such as type 2 diabetes mellitus, nonalcoholic fatty liver disease, metabolic syndrome, and cardiovascular disease, conditions once considered limited to adults. This increasing prevalence of chronic health conditions in youth closely parallels the dramatic increase in obesity, in particular abdominal adiposity, in youth. Although mounting evidence in adults demonstrates the benefits of regular physical activity as a treatment strategy for abdominal obesity, the independent role of regular physical activity alone (e.g., without calorie restriction) on abdominal obesity, and in particular visceral fat, is largely unclear in youth. There is some evidence to suggest that, independent of sedentary activity levels (e.g., television watching or playing video games), engaging in higher-intensity physical activity is associated with a lower waist circumference and less visceral fat. Several randomized controlled studies have shown that aerobic types of exercise are protective against age-related increases in visceral adiposity in growing children and adolescents. However, evidence regarding the effect of resistance training alone as a strategy for the treatment of abdominal obesity is lacking and warrants further investigation.

    2015-01-01

    Abdominal aortic aneurysm (AAA) has long been recognized as a condition predominantly afflicting males, with sex-associated differences described for almost every aspect of the disease from pathophysiology and epidemiology to morbidity and mortality. Women are generally spared from AAA formation by the immunomodulating effects of estrogen but once they develop, the natural history of AAAs in women appears to be more aggressive, with more rapid expansion, a higher tendency to rupture at smaller diameters, and higher mortality following rupture. However, simply repairing AAA at smaller diameters in women is a debatable solution, as even elective endovascular AAA repair (EVAR) is fraught with higher morbidity and mortality in women compared to men. The goal of this review is to summarize what is currently known about the effect of gender on AAA presentation, treatment, and outcomes. Additionally, we aim to review current controversies over screening recommendations and threshold for repair in women. PMID:26747679

    Recurrent acute pancreatic attacks is a rare clinical condition (2-5% of all acute pancreatis) in children and is mainly idiopathic in most cases. Sometimes it may be associated with congenital anomalies, metabolic diseases or hereditary conditions. Isovaleric acidemia (IVA) is a rare autosomal recessive amino acid metabolism disorder associated with isovaleryl coenzyme A dehydrogenase deficiency presenting the clinical findings such metabolic acidosis with increased anion gap, hyperammonemia, ketonemia, hypoglycemia, “the odor of sweaty feet,” abdominal pain, vomiting, feeding intolerance, shock and coma. Recurrent acute pancreatitis associated with IVA have been rarely reported. Herein; we report a child who admitted with recurrent acute pancreatic attacks and had the final diagnosis of IVA. Mutation analysis revealed a novel homozygous mutation of (p.E117K [c.349G>A]) in the IVA gene. Organic acidemias must kept in mind in the differential diagnosis of recurrent acute pancreatic attacks in children.

The acute effects of static stretching on speed and agility performance depend on stretch duration and conditioning level. J Strength Cond Res 30(10): 2767-2773, 2016-Although static stretching (SS) is an integral part of physical preparation before training and competition, its usefulness in regards to power performance improvement has been questioned. The aim of this study was to investigate the effect of 6 SS durations on speed and agility performance. According to a cross-over design, 34 trained men (age, 20.5 ± 1.4 years; height, 1.81 ± 0.2 m; weight, 77.2 ± 2.6 kg; body fat, 8.2 ± 2.6%) participated in a control session (no stretch) and 6 experimental conditions (10, 15, 20, 30, 40, and 60 seconds) performed in a randomized order. Performance in speed (10 and 20 m) and agility (T-test) was measured after the control and experimental conditions. Static stretching, consisting of stretches for hip extensors, hip adductors, knee extensors, knee flexors, and ankle sole flexors, was performed after light cardiovascular exercise (8 minutes). A 1-way repeated-measures analysis of variance showed that speed was improved only by SS of short duration (15/20 seconds), whereas agility remained unaffected by all SS trials. When participants' speed and agility level was taken into account, it was revealed that only those of moderate performance demonstrated an improved speed (in 15- and 20-second trials) and agility (in 10- and 15-second trials) performance. These results suggest that short-duration SS protocols induce an acute improvement of speed and agility performance, whereas longer-duration SS protocols have neither positive nor negative effect. Furthermore, it seems that individuals of lower speed and agility performance level are more likely to benefit by a short-duration SS protocol.

    Mortality and morbidity of acute lung injury and acute respiratory distress syndrome remain high because of the lack of pharmacological therapies to prevent injury or promote repair. Mesenchymal stem cells (MSCs) prevent lung injury in various experimental models, despite a low proportion of donor-derived cell engraftment, suggesting that MSCs exert their beneficial effects via paracrine mechanisms. We hypothesized that soluble factors secreted by MSCs promote the resolution of lung injury in part by modulating alveolar macrophage (AM) function. We tested the therapeutic effect of MSC-derived conditioned medium (CdM) compared with whole MSCs, lung fibroblasts, and fibroblast-CdM. Intratracheal MSCs and MSC-CdM significantly attenuated lipopolysaccharide (LPS)-induced lung neutrophil influx, lung edema, and lung injury as assessed by an established lung injury score. MSC-CdM increased arginase-1 activity and Ym1 expression in LPS-exposed AMs. In vivo, AMs from LPS-MSC and LPS-MSC CdM lungs had enhanced expression of Ym1 and decreased expression of inducible nitric oxide synthase compared with untreated LPS mice. This suggests that MSC-CdM promotes alternative macrophage activation to an M2 “healer” phenotype. Comparative multiplex analysis of MSC- and fibroblast-CdM demonstrated that MSC-CdM contained several factors that may confer therapeutic benefit, including insulin-like growth factor I (IGF-I). Recombinant IGF-I partially reproduced the lung protective effect of MSC-CdM. In summary, MSCs act through a paracrine activity. MSC-CdM promotes the resolution of LPS-induced lung injury by attenuating lung inflammation and promoting a wound healing/anti-inflammatory M2 macrophage phenotype in part via IGF-I. PMID:23023971

We searched for systematic reviews in 10 online databases, bibliographic references, and hand-searches in yoga-related journals. Included reviews satisfy Oxman criteria and specify yoga as a primary intervention in one or more randomized controlled trials for treatment in adults. The AMSTAR tool and GRADE approach evaluated the methodological quality of reviews and quality of evidence. Results. We identified 2202 titles, of which 41 full-text articles were assessed for eligibility and 26 systematic reviews satisfied inclusion criteria. Thirteen systematic reviews include quantitative data and six papers include meta-analysis. The quality of evidence is generally low. Sixteen different types of health conditions are included. Eleven reviews show tendency towards positive effects of yoga intervention, 15 reviews report unclear results, and no, reviews report adverse effects of yoga. Yoga appears most effective for reducing symptoms in anxiety, depression, and pain. Conclusion. Although the quality of systematic reviews is high, the quality of supporting evidence is low. Significant heterogeneity and variability in reporting interventions by type of yoga, settings, and population characteristics limit the generalizability of results.

    Overcoming resistance to chemotherapy is the main therapeutic challenge in the treatment of acute lymphocytic leukemia (ALL). Interactions between leukemia cells and the microenvironment promote leukemia cell survival and confer resistance to chemotherapy. Hypoxia is an integral component of bone marrow (BM) microenvironment. Hypoxia-inducible factor-1α (HIF-1), a key regulator of the cellular response to hypoxia, regulates cell growth and metabolic adaptation to hypoxia. HIF-1α expression, analyzed by Reverse Phase Protein Arrays in 92 specimens from newly diagnosed patients with pre-B-ALL, had a negative prognostic impact on survival (p = 0.0025). Inhibition of HIF-1α expression by locked mRNA antagonist (LNA) promoted chemosensitivity under hypoxic conditions, while pharmacological or genetic stabilization of HIF-1α under normoxia inhibited cell growth and reduced apoptosis induction by chemotherapeutic agents. Co-culture of pre-B ALL or REH cells with BM-derived mesenchymal stem cells (MSC) under hypoxia resulted in further induction of HIF-1α protein and acquisition of the glycolytic phenotype, in part via stroma-induced AKT/mTOR signaling. mTOR blockade with everolimus reduced HIF-1α expression, diminished glucose uptake and glycolytic rate and partially restored the chemosensitivity of ALL cells under hypoxia/stroma co-cultures. Hence, mTOR inhibition or blockade of HIF-1α-mediated signaling may play an important role in chemosensitization of ALL cells under hypoxic conditions of the BM microenvironment. PMID:22785211

  14. Ultrasound Screening for Abdominal Aortic Aneurysm

    PubMed Central

    2006-01-01

    Executive Summary Objective The aim of this review was to assess the effectiveness of ultrasound screening for asymptomatic abdominal aortic aneurysm (AAA). Clinical Need Abdominal aortic aneurysm is a localized abnormal dilatation of the aorta greater than 3 cm. In community surveys, the prevalence of AAA is reported to be between 2% and 5.4%. Abdominal aortic aneurysms are found in 4% to 8% of older men and in 0.5% to 1.5% of women aged 65 years and older. Abdominal aortic aneurysms are largely asymptomatic. If left untreated, the continuing extension and thinning of the vessel wall may eventually result in rupture of the AAA. Often rupture may occur without warning, causing acute pain. Rupture is always life threatening and requires emergency surgical repair of the ruptured aorta. The risk of death from ruptured AAA is 80% to 90%. Over one-half of all deaths attributed to a ruptured aneurysm take place before the patient reaches hospital. In comparison, the rate of death in people undergoing elective surgery is 5% to 7%; however, symptoms of AAA rarely occur before rupture. Given that ultrasound can reliably visualize the aorta in 99% of the population, and its sensitivity and specificity for diagnosing AAA approaches 100%, screening for aneurysms is worth considering as it may reduce the incidence of ruptured aneurysms and hence reduce unnecessary deaths caused by AAA-attributable mortality. Review Strategy The Medical Advisory Secretariat used its standard search strategy to retrieve international health technology assessments and English-language journal articles from selected databases to determine the effectiveness of ultrasound screening for abdominal aortic aneurysms. Case reports, letters, editorials, nonsystematic reviews, non-human studies, and comments were excluded. Questions asked: Is population-based AAA screening effective in improving health outcomes in asymptomatic populations? Is AAA screening acceptable to the population? Does this affect the

    To examine the effects of heat and noise individually and jointly on certain physiological responses and cognitive and neuromotor based functions, 12 male participants were tested under 6 experimental conditions which resulted by combining 3 levels of heat (25 degrees, 30 degrees and 35 degrees C) and 2 levels of white noise (70 and 100 dB). The experiment was carried out in a controlled climatic chamber following two 6 x 6 latin square designs. The results indicated elevations in heart rate, oxygen uptake and body temperature due to the independent effect of heat or the combined effects of heat and noise. The independent action of noise was found to be depressive on the first two responses. On the neuropsychological effects, the heat adversely affected the speed in card sorting (by design configuration) and digit symbol tests, and also the accuracy and error rate in the reasoning ability test. The noise caused performance improvements in critical flicker frequency (simultaneous) and in error rates in card sorting (by design configuration). The combined effects of heat and noise indicated higher error rates in card sorting (by face value), decreased accuracy in reasoning ability and improvements in performance in accuracy scores and error rates in digit symbol test.

    A 44-year-old Hispanic woman presented to the emergency room with a 2-day history of sudden onset of severe cramping left lower quadrant abdominal pain associated with ∼20 episodes diarrhoea. Abdominal CT scan exhibited bowel wall oedema and acute extensive colitis. On the basis of the preliminary diagnosis of acute abdomen, the patient was admitted under the surgical team and treated for acute colitis. Since her family history was significant for hereditary angioedema (HAE), complement studies were performed which revealed low complement C4 levels and abnormally low values of C1q esterase inhibitor. Thus, the diagnosis of HAE type I was established. This case report summarises that the symptoms of HAE are often non-specific, hence making the underlying cause difficult to diagnose.

    PubMed Central

    1986-01-01

    Human hepatoma cells mimic the acute phase response after treatment with monocyte-conditioned medium. Levels of secreted fibrinogen, alpha- 1 acid glycoprotein, C-reactive protein, haptoglobin, and the third component of complement were elevated compared with control levels after 48 h of incubation with conditioned supernatant medium from an enriched fraction of normal peripheral monocytes. Albumin levels declined and alpha-1 antitrypsin remained unchanged. Levels of specific mRNA were measured by hybridization to slot blots and Northern blots and changed in correspondence with protein alterations. Interleukin-1 and tumor necrosis factor stimulated the third component of complement, but did not elevate any other member of the acute phase group and were therefore only partially active in this system. The identification of an in vitro model of the human acute phase response will permit analysis of the molecular basis for coordinate regulation of this group of facultative genes. PMID:3017995

    Abdominal wall reconstruction is a highly complex procedure that may requires a multiple stages surgical operations. The aim of a such reconstruction is to close the abdominal wall defect and to create a support for the internal organs. It's a challenge for both general and reconstructive surgery. An incomplete thickness defects of the abdominal wall are so much easier to challenge than complete ones. Also the size of the primary defect determines the way and stages of the operation. Such defects can occur in necrotizing fasciitis of the abdominal wall, after abdominal walls tumors removal, in traffic accidents or after "open abdomen" procedures (acute severe pancreatitis). In this paper the authors present a case of 62-yo patient which was operated because of large intestine perforation with various complications of which the most serious was the abdominal wall defect.

    It is often difficult to differentiate acute pancreatitis (A.P.) from some other acute abdominal diseases, when there is an elevated serum amylase. In contrast, the renal clearance of amylase, expressed as a percentage of creatinine clearance, can separate patients with A.P. from patients with acute colecistitis, common duct stone without pancreatitis, hyperamylasemia after biliary surgery, acute peptic ulcer and acute salivary diseases.

    348 cases of abdominal aortic aneurysm were reviewed for typical features of inflammatory aneurysm (IAAA) (marked thickening of aneurysm wall, retroperitoneal fibrosis and rigid adherence of adjacent structures). IAAA was present in 15 cases (14 male, 1 female). When compared with patients who had ordinary aneurysms, significantly more patients complained of back or abdominal pain (p less than 0.01). Erythrocyte sedimentation rate was highly elevated. Diagnosis was established in 7 of 10 computed tomographies. 2 patients underwent emergency repair for ruptured aneurysm. Unilateral ureteral obstruction was present in 4 cases and bilateral in 1. Repair of IAAA was performed by a modified technique. Histological examination revealed thickening of the aortic wall, mainly of the adventitial layer, infiltrated by plasma cells and lymphocytes. One 71-year-old patient operated on for rupture of IAAA died early, and another 78-year-old patient after 5 1/2 months. Control computed tomographies revealed spontaneous regression of inflammatory infiltration after repair. Equally, hydronephrosis due to ureteral obstruction could be shown to disappear or at least to decrease. IAAA can be diagnosed by computed tomography with high sensitivity. Repair involves low risk, but modification of technique is necessary. The etiology of IAAA remains unclear.

    This study aimed to evaluate the morbidity and pregnancy outcome of myomectomy in infertile women with uterine fibroids. This was a cross-sectional study. Records were reviewed for 100 consecutive women in the Rotunda Hospital who underwent myomectomy in the years 1995-1996. A questionnaire regarding subsequent fertility was sent. The study was carried out in the infertility unit at the Rotunda Hospital, Dublin, Ireland. Seventy-five women responded. Multiple myomectomy was performed in 52 (70%). Mean fibroid size was 6.8 cm (range 2-14.5 cm). Nine women (12%) developed complications; five had menstrual problems, two had wound discomfort and two had abdominal discomfort. Twenty-five women (33%) became pregnant. Seven (28%) were IVF pregnancies. Overall six (24%) miscarried. In 19 of 25, pregnancy occurred where fibroids were the only identifiable cause of infertility. We conclude that abdominal myomectomy is associated with a favourable outcome in infertile women particularly if no other confounding variable is present.

    The incidence of invasive mycoses in patients undergoing abdominal surgery amounts to approximately 8% and shows an upward trend in epidemiological studies. The lethality of these systemic mycoses, which are mostly based on Candida infections constitutes up to 60%. The development of a sytemic mycosis is marked by exogenic, endogenic and iatrogenic risk factors and typically displays tissue invasion after an initial fungal contamination or systemic dissemination via fungal sepsis. Fungal peritonitis is generally a monoinfection with Candida spp., where Candida albicans outweighs in 70% of cases. Aspergillus spp. are only detected abdominally in rare cases. The histological verification of a fungal invasion is regarded as proof of the existence of an invasive mycosis, but typical macroscopic findings with corresponding cultural findings can also confirm the diagnosis. Systemic mycosis requires an early initiation of a consistent antimycotic therapy as well as definitive surgical eradication of the focus in order to reduce high lethal rate. Resistances or incorrect dosages can be validated objectively by means of histological monitoring of the antimycotic therapy, thus affording early recognition of the need to change the substance class.

    Objective We aimed to evaluate the safety and efficacy of a fixed-dose combination (FDC) of tramadol and diclofenac versus a standard approved FDC of tramadol and paracetamol, in patients with acute moderate to severe pain. Methods A total of 204 patients with moderate to severe pain due to acute musculoskeletal conditions (n=52), acute flare of osteoarthritis (n=52), acute flare of rheumatoid arthritis (n=50), or postoperative pain (n=50) were enrolled in the study at baseline. Each disease category was then randomized to receive either of two treatments for 5 days: group A received an FDC of immediate-release tramadol hydrochloride (50 mg) and sustained-release diclofenac sodium (75 mg) (one tablet, twice daily), and group B received an FDC of tramadol hydrochloride (37.5 mg) and paracetamol (325 mg) (two tablets every 4–6 hours, up to a maximum of eight tablets daily). The primary efficacy end points were reductions in pain intensity from baseline at day 3 and day 5 as assessed by a Visual Analog Scale (VAS) score. Results Group A showed a significant reduction in the VAS score for overall pain from baseline on day 3 (P=0.001) and day 5 (P<0.0001) as compared with group B. The combination of tramadol-diclofenac resulted in few mild to moderate adverse events (nausea, vomiting, epigastric pain, and gastritis), which required minimal management, without any treatment discontinuation. The number of adverse events in group A was nine (8.82%) compared with 22 (21.78%) in group B, after 5 days of treatment. Conclusion An FDC of tramadol-diclofenac showed a significantly greater reduction in pain intensity and was well tolerated compared with tramadol-paracetamol, resulting in better analgesia in patients suffering from moderate to severe pain due to acute musculoskeletal conditions, postoperative pain following orthopedic surgery, or acute flare of osteoarthritis and rheumatoid arthritis.

    Acute pancreatitis is a common emergency within abdominal disease. It is accepted that two of three conditions must be fulfilled for its diagnosis: characteristic clinical presentation, characteristic laboratory findings, and/or characteristic diagnostic imaging findings. The first two conditions are the most often used, probably for reasons of efficiency and frequency. Nevertheless, the need for imaging studies is sometimes a source of conflict. For this reason, we decided to review the current evidence regarding the indication of urgent imaging tests in the management of acute pancreatitis.

    Reduced-intensity conditioning (RIC) regimens extend the therapeutic use of allogeneic hematopoietic cell transplantation (HCT) to older patients. The survival trend in 2325 patients aged >50 years presenting with de novo acute myeloid leukemia (AML) who underwent first reduced-intensity HCT (RIC-HCT) was assessed by retrospectively analyzing outcomes between 2000 and 2013. The annual number of RIC-HCTs in Japan was higher in the 2008-2013 period (n = 205/year [1229/6 years]) than in the 2000-2007 period (n = 137/year [1096/8 years]). Overall and disease-free survival were higher in the 2008-2013 period (P < 0.001) because of the improvement in transplant-related mortality (TRM). Survival regarding RIC-HCT for AML has improved over time, with an increased number of RIC-HCTs in patients with a Karnofsky performance status (KPS) ≥80. However, TRM remains high and the relapse rate has not improved over time. Multivariate analyses showed that a KPS ≥80 and complete remission at HCT were associated with less TRM and relapse, and better survival regardless of age ≥65 years. Accurate timing and prospective identification of patients at risk of TRM may aid the development of risk-adapted strategies for RIC-HCT in AML patients regardless of age.

    The impact of pre transplant (HCT) cytarabine consolidation therapy on post HCT outcomes has yet to be evaluated after reduced intensity or non-myeloablative conditioning. We analyzed 604 adults with acute myeloid leukemia (AML) in first complete remission (CR1) reported to the CIBMTR who received a RIC or NMA HCT from an HLA-identical sibling, HLA-matched unrelated donor (URD), or umbilical cord blood (UCB) donor in 2000–2010. We compared transplant outcomes based on exposure to cytarabine post remission consolidation. Three year survival rates were 36% (29–43%, 95% CI) in the no consolidation arm and 42% (37–47%, 95% CI) in the cytarabine consolidation arm (p=0.16). Disease free survival was 34% (27–41%, 95% CI) and 41% (35–46%, 95% CI) (p=0.15), respectively. Three year cumulative incidences of relapse were 37% (30–44%, 95% CI) and 38% (33–43%, 95% CI), respectively (p=0.80). Multivariate regression confirmed no effect of consolidation on relapse, DFS and survival. Prior to RIC/NMA HCT, these data suggest pre-HCT consolidation cytarabine does not significantly alter outcomes and support prompt transition to transplant as soon as morphologic CR1 is attained. If HCT is delayed while identifying a donor, our data suggest that consolidation does not increase transplant TRM and is reasonable if required. PMID:24184335

    In this study, we examined whether functional subunits of the ATP-dependent K+ channel (KATP) are expressed in trigeminal ganglia (TG), which contains sensory neurons that innervate oral and facial structures. We also investigated whether direct activation of the KATP effectively attenuates mechanical hypersensitivity in the context of an acute orofacial muscle pain condition. The KATP expression in TG and behavioral studies were conducted in age matched male and female Sprague Dawley rats. RT-PCR experiments showed that the mRNAs for the inwardly rectifying pore-forming subunits, Kir6.1 and Kir6.2, as well as the regulatory sulphonylurea subunits, SUR1 and SUR2, were reliably detected in TG. Subsequent western blot analysis confirmed that proteins for all 4 subunits are expressed in TG, and showed that Kir6.2 is expressed at a significantly higher level in male TG compared to that of female rats. This observation was confirmed by the immunohistochemical demonstration of higher percentages of Kir6 positive masseter afferents in female rats. Masseteric injection of capsaicin evokes a time dependent increase in masseter sensitivity to noxious mechanical stimulation. A specific KATP agonist, pinacidil, dose-dependently attenuated the capsaicin-induced mechanical hypersensitivity in male rats. The dose of pinacidil (20µg) that completely blocked the capsaicin responses in male rats was ineffective in female rats regardless of their estrus phases. Only at the highest dose (300µg) we used, pinacidil was partially effective in female rats. Similarly, another KATP agonist, diazoxide which targets different KATP subunits also showed sex specific responses in attenuating capsaicin-induced masseter hypersensitivity. These data suggested that sex differences in functional KATP expression in TG may underlie sex specific responses to KATP agonists. The present study provided novel information on sex differences in KATP expression in TG and its contribution under an orofacial

    Objectives Depression is associated with increased morbidity and mortality rates among cardiovascular patients. Depressed patients have three times higher risk of death than those who are not. We sought to determine the presence of depressive symptoms, and whether gender and age are associated with depression among Arab patients hospitalised with cardiac conditions in a Middle Eastern country. Setting Using a non-probability convenient sampling technique, a cross-sectional survey was conducted with 1000 Arab patients ≥20 years who were admitted to cardiology units between 2013 and 2014 at the Heart Hospital in Qatar. Patients were interviewed 3 days after admission following the cardiac event. Surveys included demographic and clinical characteristics, and the Arabic version of the Beck Depression Inventory Second Edition (BDI-II). Depression was assessed by BDI-II clinical classification scale. Results 15% of the patients had mild mood disturbance and 5% had symptoms of clinical depression. Twice as many females than males suffered from mild mood disturbance and clinical depression symptoms, the majority of females were in the age group 50 years and above, whereas males were in the age group 40–49 years. χ2 Tests and multivariate logistic regression analyses indicated that gender and age were statistically significantly related to depression (p<0.001 for all). Conclusions Older Arab women are more likely to develop mood disturbance and depression after being hospitalised with acute cardiac condition. Gender and age differences approach, and routine screening for depression should be conducted with all cardiovascular patients, especially for females in the older age groups. Mental health counselling should be available for all cardiovascular patients who exhibit depressive symptoms. PMID:27388362

    The decision to operate for abdominal pain in patients with leukopenia can be exceedingly difficult. Surgical exploration may be the only effective way to differentiate acute appendicitis from other causes, but it involves considerable risk of infectious complications due to immunesuppression. Leukemic patients, who presented significant RLQ pain, had been indicated for operation, despite having advanced disease or having had received chemotherapy or steroids. Four adult leukemia patients, complicated by acute appendictis, were reviewed. Two patients were in induction chemotherapy, one receiving salvage chemotheapy due to relapse and the other was in conservative treatment. Two patients were acute myelocytic leukemia (AML), one had acute lymphocytic leukemia (ALL), and the other had aleukemic leukemia. All patients underwent appendectomy and recovered without complication. Our experience supports the theory that the surgical management of appendicitis in acute leukemia is the most effective way, in spite of leukopenia. PMID:8268146

    The optimal conditioning regimen for allogeneic hematopoietic stem cell transplantation (allo-HSCT) in acute leukemia remains undefined. We evaluated the outcomes in 30 patients with acute leukemia who underwent allo-HSCT from human leukocyte antigen-matched donors after conditioning with busulfan and fludarabine (BuFlu). The regimen comprised injection of busulfan 3.2 mg/kg daily on 4 consecutive days and fludarabine 30 mg/m2 daily for 4 doses. All 30 patients achieved hematopoiesis reconstitution with full donor chimerism confirmed by short tandem repeat DNA analysis. The most common regimen-related toxicity was mucositis (86.7%), followed by cytomegalovirus infection (80%). Serious regimen-related toxicities were rare. Acute graft vs. host disease (aGVHD) was detected in 46.7% of the patients; 33.4% had grade I–II aGVHD and 13.3% had grade III–IV aGVHD. Chronic GVHD (cGVHD) was noted in 20% of the patients. The overall survival and disease-free survival rates were 66.7 and 53%, respectively, with a median follow-up of 25 months for surviving patients. Therefore, BuFlu was an effective conditioning regimen with a low rate of transplant-related adverse effects and increased antileukemic effects in patients with acute leukemia undergoing allo-HSCT.

    Intraabdominal tuberculosis (TB) presents with a wide variety of clinical and radiologic features. Besides the reported computed tomographic (CT) finding of high-density ascites in tuberculous peritonitis, this report describes additional CT features highly suggestive of abdominal tuberculosis in eight cases: (1) irregular soft-tissue densities in the omental area; (2) low-density masses surrounded by thick solid rims; (3) a disorganized appearance of soft-tissue densities, fluid, and bowel loops forming a poorly defined mass; (4) low-density lymph nodes with a multilocular appearance after intravenous contrast administration; and (5) possibly high-density ascites. The differential diagnosis of these features include lymphoma, various forms of peritonitis, peritoneal carcinomatosis, and peritoneal mesothelioma. It is important that the CT features of intraabdominal tuberculosis be recognized in order that laparotomy be avoided and less invasive procedures (e.g., laparoscopy, biopsy, or a trial of antituberculous therapy) be instituted.

    Abdominal emergencies can also be operated on through the laparoscopic approach: the approach can be diagnostic laparoscopy, surgery assisted by laparoscopy or laparotomy directed according to the findings of the laparoscopy. The general contraindications refer above all to the state of haemodynamic instability of the patient and to seriously ill patients (ASA IV). In the absence of any specific counter-indications for the specific laparoscopic procedure to be carried out, many abdominal diseases requiring emergency surgery can be performed with the laparoscopic approach. The most frequent indications are appendicitis, acute colecistitis, gastroduodenal perforation, occlusion of the small intestine, and some abdominal traumas. With a correct selection of patients and the appropriate experience of the surgeon, the results are excellent and better than open surgery (less infection of the wound, complications, hospital stay and postoperative pain). A detailed explanation is given of the basic aspects of the surgical technique in the most frequent procedures of emergency laparoscopy.

    Abstract Surgery-induced acute postoperative pain may lead to prolonged convalescence. The present study was designed to investigate the effects of intraoperative dexmedetomidine on postoperative analgesia following abdominal colectomy surgeries. Eighty patients scheduled for abdominal colectomy surgery under general anesthesia were divided into 2 groups, which were maintained using propofol/remifentanil/dexmedetomidine (PRD) or propofol/remifentanil/saline (PRS). During surgery, patients in the PRD group had a lower bispectral index (BIS) value, which indicated a deeper anesthetic state, and a higher sedation score right after extubation than patients in the PRS group. During the first 24 hours post surgery, PRD patients consumed less morphine in patient-controlled analgesia (PCA) and had a lower score in the visual analog scale (VAS) testing than their controls from the PRS group. Intraoperative administration of dexmedetomidine appears to promote the analgesic property of morphine-based PCA in patients after abdominal colectomy. PMID:26376397

    We report the relative efficacy of co-infusing 2 umbilical cord blood units (dUCB) compared with peripheral blood progenitor cells (PBPCs) from 8 of 8 or 7 of 8 HLA-matched unrelated donors. All patients received reduced-intensity conditioning (RIC) regimens. Four treatment groups were evaluated: 4-6 of 6 matched dUCB-TCF (n = 120; TCF = total body irradiation [TBI] 200 cGy + cyclophos-phamide + fludarabine), 4-6 of 6 matched dUCB-other (n = 40; alkylating agent + fludarabine ± TBI), and 8 of 8 (n = 313) and 7 of 8 HLA-matched PBPCs (n = 111). Compared with matched 8 of 8 PBPC transplantations, transplantation-related mortality (TRM), and overall mortality were similar after dUCB-TCF (relative risk [RR] 0.72, P = .72; RR 0.93, P = .60) but higher after dUCB-other RIC (hazard ratio [HR] 2.70, P = .0001; 1.79 P = .004). Compared with 7 of 8 PBPC transplantations, TRM (but not overall mortality) was lower after dUCB-TCF (RR 0.57, P = .04; RR 0.87 P = .41). The probabilities of survival after dUCB-TCF, dUCB-other RIC, and 8 of 8 PBPC and 7 of 8 PBPC transplantations were 38%, 19%, 44%, and 37%, respectively. With similar survival after 8 of 8, 7 of 8 matched PBPCs, and dUCB-TCF, these data support use of dUCB-TCF transplantation in adults with acute leukemia who may benefit from RIC transplantation urgently or lack a 7-8 of 8 unrelated donor.

    Selective serotonin and noradrenalin reuptake inhibitors such as fluoxetine and desipramine, respectively, are efficacious in the treatment of depression and chronic stress. Although they inhibit the reuptake of the biogenic monoamines soon after administration, therapeutic improvements occur only after 2 or 3 weeks. Freezing response and potentiated startle are common responses to moderate fear contextual conditioning. However, freezing but not startle is increased in rats that undergo intense fear conditioning. In this study, we evaluated the effects of acute and subchronic administration of fluoxetine and desipramine on these responses in testing sessions, as indices of fear in moderate and high fear conditioning. Fluoxetine did not show any significant effect on the moderate fear conditioning but reduced freezing and restored the startle response in rats under intense fear conditioning. In comparison, desipramine had no effect on the startle response when administered acutely or subchronically while freezing of the intense fear conditioning was reduced. Our findings indicate that intense contextual fear conditioning is sensitive to subchronic treatment with fluoxetine and resistant to desipramine. Fluoxetine appears to restore the serotoninergic function in brain areas recruited by intense contextual fear conditioning. These effects of fluoxetine may underlie its reported efficacy in the pharmacotherapy of panic disorders.

    We evaluated the effect of acute and chronic graft-versus-host disease (GVHD) on relapse and survival after allogeneic haematopoietic stem cell transplantation (HSCT) for multiple myeloma (MM) using non-myeloablative conditioning (NMA) and reduced-intensity conditioning (RIC). The outcomes of 177 HLA-identical sibling HSCT recipients between 1997 and 2005 following NMA (n=98) or RIC (n=79) were analyzed. In 105 patients, autografting was followed by planned NMA/RIC allogeneic transplantation. The impact of GVHD was assessed as a time-dependent covariate using Cox models. The incidence of acute GVHD (grades I–IV) was 42% (95% confidence interval (CI) 35 – 49%) and of chronic GVHD at five years was 59% (95% CI 49 – 69%), with 70% developing extensive chronic GVHD. In multivariate analysis, acute GVHD (≥ grade I) was associated with an increased risk of TRM (relative risk (RR)=2.42; p=0.016), whereas limited chronic GVHD significantly decreased the risk of myeloma relapse (RR=0.35, p=0.035) and was associated with superior event-free survival (RR=0.40, p=0.027). Acute GVHD had a detrimental effect on survival, especially in those receiving autologous followed by allogeneic HSCT (RR=3.52; p=0.001). The reduction in relapse risk associated with chronic GVHD is consistent with a beneficial graft-versus-myeloma effect, but this did not translate into a survival advantage. PMID:21946381

    This is a multivariate analysis of the data recorded in assessing 1158 consecutive admissions presenting to a children's surgical ward with acute abdominal pain. There were 56 binary variables available for entry into the analysis. A statistical software package was used to perform a stepwise discriminant analysis on the data. The program selected 18 variables as having discriminating power in assigning patients to the six diagnostic groups. In order of discriminating power these were, mainly, a positive urine culture, the bowel history, the findings on rectal examination, the location of abdominal tenderness, the presence of a mass, and the white cell count. Lesser discriminating potential was assigned to the presence of dehydration; fluid levels on erect abdominal films, a rise in temperature, an increased pulse rate, the presence of urinary symptoms, and the general appearance of the child. Use of these data led to an overall correct classification of 80.7% of cases. It is concluded that these variables should be included in the assessment of children with acute abdominal pain.

    To carry out an abdominal ultrasound examination with the highest degree of accuracy and thoroughness, it is essential to have a good knowledge of the anatomy and the normal measurements of the different organs. In this way, we can determine their normal condition and identify the pathology and its location more easily. It is very important to adopt a correct examination procedure, systematically sweeping the scan in the same direction and not leaving any organ unexamined. We suggest a procedure consisting of longitudinal, cross-sectional and oblique scans to view all the abdominal organs, starting the examination in the epigastric region, scanning first the right upper quadrant, then the left upper quadrant, both iliac fossa, and lastly the hypogastric region.

    The economic aspects of abdominal wall reconstruction are frequently overlooked, although understandings of the financial implications are essential in providing cost-efficient health care. Ventral hernia repairs are frequently performed surgical procedures with significant economic ramifications for employers, insurers, providers, and patients because of the volume of procedures, complication rates, the significant rate of recurrence, and escalating costs. Because biological mesh materials add significant expense to the costs of treating complex abdominal wall hernias, the role of such costly materials needs to be better defined to ensure the most cost-efficient and effective treatments for ventral abdominal wall hernias.

    In spite of careful intraoperative precautions and gauze counts, mistakes can still occur during surgery. In the case reported, a retained gauze leaved during a surgical approach for removing a solid-cystic papillary tumor localized in the pancreatic tail, caused both persistent abdominal discomfort and the presence of an abdominal cystic lesion at imaging techniques. When a previous operative history is present, a foreign body should be taken into account in the differential diagnosis of a patient with an intra-abdominal cystic mass. Finally, radio-opaque marker should be routinely used by surgeons in order to reach a correct diagnosis in operated patients having retained gauze.

    We report herein a case of an incorrectly applied Heimlich maneuver--to the best of our knowledge, the first reported fatal complication associated with a Heimlich maneuver, acute thrombosis of an abdominal aortic aneurysm, and the distal aorta. While the Heimlich maneuver is effective for the relief of foreign body-induced upper airway obstruction, increased efforts should be directed toward instructing the public in correctly recognizing and optimally treating airway obstruction.

  10. Flow topology in patient-specific abdominal aortic aneurysms during rest and exercise

    Abdominal aortic aneurysm (AAA) is a permanent, localized widening of the abdominal aorta. Flow in AAA is dominated by recirculation, transitional turbulence and low wall shear stress. Image-based CFD has recently enabled high resolution flow data in patient-specific AAA. This study aims to characterize transport in different AAAs, and understand flow topology changes from rest to exercise, which has been a hypothesized therapy due to potential acute changes in flow. Velocity data in 6 patients with different AAA morphology were obtained using image-based CFD under rest and exercise conditions. Finite-time Lyapunov exponent (FTLE) fields were computed from integration of the velocity data to identify dominant Lagrangian coherent structures. The flow topology was compared between rest and exercise conditions. For all patients, the systolic inflow jet resulted in coherent vortex formation. The evolution of this vortex varied greatly between patients and was a major determinant of transport inside the AAA during diastole. During exercise, previously observed stagnant regions were either replaced with undisturbed flow, regions of uniform high mixing, or persisted relatively unchanged. A mix norm measure provided a quantitative assessment of mixing. This work was supported by the National Institutes of Health, grant number 5R21HL108272.

    We have reviewed the medical records of 111 patients treated for abdominal stab wounds during the period 1980-87. Our two hospitals serve a catchment area of about 450,000 people. Exploratory laparotomy was performed in 89 patients with suspected peritoneal penetration. In 16 patients the laparotomy was negative, and in 15 patients only minor injuries were noted. There were no serious complications in these 31 patients. Twenty-seven patients had thoracic wounds below the fourth intercostal space, 15 with intraabdominal injuries. The most common injuries were lacerations of the liver, the small bowel and the diaphragm. The mortality in the series was 2%. Stab wounds are infrequent in Norway, and most surgeons have limited experience of such injuries. We discuss whether to employ immediate exploratory laparotomy or selective management when the peritoneum has been penetrated. When there is no evidence of evisceration or omental protrusion, local exploration of the wound should be performed in order to confirm or exclude peritoneal penetration. Injury to the diaphragm and intraabdominal viscera should always be suspected in thoracic stab wounds below the fourth intercostal space.

    A 79-year-old woman presented to a private medical practice 2 years previously for an elective ultrasound screening scan. This imaging provided the evidence for a diagnosis of an abdominal aortic aneurysm (AAA) to be made. Despite having a number of recognised risk factors for an AAA, her general practitioner at the time did not follow the guidance set out by the private medical professional, that is, to refer the patient to a vascular specialist to be entered into a surveillance programme and surgically evaluated. The patient became symptomatic with her AAA, was admitted to hospital and found to have a tender, symptomatic, 6 cm leaking AAA. She consented for an emergency open AAA repair within a few hours of being admitted to hospital, despite the 50% perioperative mortality risk. The patient spent 4 days in intensive care where she recovered well. She was discharged after a 12 day hospital stay but unfortunately passed away shortly after her discharge from a previously undiagnosed gastric cancer.

    Arteriosclerotic abdominal aortic aneurysms are present in a least 2% of the elderly population of the Western world and their number is increasing. Without treatment 30% of patients with asymptomatic aneurysms live for 5 years, although the risk of rupture becomes greater as the size of the aneurysm increases. Of those with untreated symptomatic aneurysms 80% are dead within a year. Elective repair of aneurysms has a low mortality, and 50% of the patients live for at least 5 years. Symptomatic aneurysms all cause pain and may produce other symptoms from pressure on adjacent structures, distal embolism, acute thrombosis or rupture. In 88% of cases an aneurysm can be diagnosed by physical examination alone; confirmatory tests include soft-tissue roentgenography of the abdomen, ultrasonography, computer-assisted tomography and aortography. Repair is indicated for symptomatic or ruptured aortic aneurysms and for asymptomatic aneurysms over 5 cm in diameter. Early diagnosis and referral for repair is essential for optimum treatment of this common condition. PMID:7004617

    Consecutive patients undergoing emergency appendectomy (283) or urgent cholecystectomy (51) were prospectively studied for the development of post-operative incisional or peritoneal sepsis. Severity of the original peritoneal infection was carefully recorded, while use of a Penrose dam to drain the peritoneum was randomized according to pre-assigned hospital number. Both aerobic and anaerobic cultures were taken from the abdomen at the time of operation as well as from all postoperative infectious foci. Results demonstrated no essential differences in incidence of wound and peritoneal infection following appendectomy for simple or suppurative appendicitis (187) or following cholecystectomy for acute cholecystitis (51). However, with gangrenous or perforative appendicitis (94), incisional and intra-abdominal infection rates were 43% and 45%, respectively, when a drain was used; yet only 29 and 13%, respectively, without a drain. These latter differences were significant (p < 0.001). In addition, intra-abdominal abscesses were three times as likely to drain through the incision than along any tract provided by the rubber conduit. Cultures revealed that hospital pathogens accounted for a greater proportion of wound and peritoneal sepsis after cholecystectomy and appendectomy for simple or suppurative appendicitis if a drain had been inserted than if managed otherwise. By contrast, a mixed bacterial flora was responsible for most infections following appendectomy for gangrenous or perforated appendicitis, irrespective as to use of a drain. PMID:646499

We report a case of thigh emphysema in an 88-year-old patient with diabetes. Prior to admission the patient reported a vague 4-week history of left thigh pain and an inability to fully weight bear. She presented to our emergency department with sepsis and acute kidney impairment. An X-ray of her left femur revealed widespread gas between muscular planes. A retroperitoneal abscess involving the left renal fossa, psoas, iliacus and upper thigh muscles was revealed on an urgent CT scan. The patient was transferred to intensive care unit (ICU) and underwent an emergency drainage. Despite ICU the patient died 2 days after admission. PMID:25576509

    Acute acetaminophen (ACT) ingestion has been reported to reduce thermal strain during cycling in the heat. In this study, nine active participants ingested 20 mg of ACT per kg of total body mass (ACT) or a placebo (PLA), 60 min prior to cycling at a fixed rate of metabolic heat production (ACT: 8.3 ± 0.3 W/kg; PLA: 8.5 ± 0.5 W/kg), which was equivalent to 55 ± 6% VO2max , for 60 min at 34.5 ± 0.1 °C, 52 ± 1% relative humidity. Resting rectal temperature (Tre ; ACT: 36.70 ± 0.17 °C; PLA: 36.80 ± 0.16 °C, P = 0.24), esophageal temperature (Tes ; ACT: 36.54 ± 0.22 °C; PLA: 36.61 ± 0.17 °C, P = 0.50) and mean skin temperature (Tsk ; ACT: 34.00 ± 0.14 °C; PLA: 33.96 ± 0.20 °C, P = 0.70) were all similar among conditions. At end-exercise, no differences in ΔTre (ACT: 1.12 ± 0.15 °C; PLA: 1.11 ± 0.21 °C, P = 0.92), ΔTes (ACT: 0.90 ± 0.28 °C; PLA: 0.88 ± 0.23 °C, P = 0.84), ΔTsk (ACT: 0.80 ± 0.39 °C; PLA: 0.70 ± 0.46 °C, P = 0.63), mean local sweat rate (ACT: 1.02 ± 0.15 mg/cm(2) /min; PLA: 1.02 ± 0.13 mg/cm(2) /min, P = 0.98) and whole-body sweat loss (ACT: 663 ± 83 g; PLA: 663 ± 77 g, P = 0.995) were evident. Furthermore, ratings of perceived exertion and thermal sensation and thermal comfort were not different between ACT and PLA conditions. In conclusion, ACT ingested 60 min prior to moderate intensity exercise in hot-humid conditions does not alter physiologic thermoregulatory control nor perceived strain.

    The incidence of acute bleeding is reported to be 13.5% in patients with acute necrotizing pancreatitis. However, of all the bleeding events, intra-abdominal bleeding was less studied in the literature and its risk factors have not been well defined yet. The purpose of the present study was to investigate the risk factors for massive intra-abdominal bleeding among the patients with infected necrotizing pancreatitis and assessed the outcome of these patients. Both univariate and multivariate logistic regression models were applied for evaluating risk factors for intra-abdominal bleeding using 33 indices, including age, sex, etiology of acute pancreatitis (AP), APACHE II score, etc. Outcome assessments such as mortality, hospital and intensive care unit (ICU) durations, and cost were also compared between patients with or without intra-abdominal bleeding. Acute kidney injury (AKI) (odds ratio [OR]: 7.54, 95% confidence interval [CI]: 2.53-22.52, P < 0.001) and number of operation (OR: 8.84, 95% CI: 2.01-38.86, P = 0.004) were 2 predictors for massive intra-abdominal bleeding in the patients with infected necrotizing pancreatitis. In addition, AP patients with intra-abdominal bleeding also showed significantly higher mortality rate, prolonged hospital and ICU durations, more complications and invasive treatments, as well as increased cost. Our study revealed that AKI and multiple operations were 2 critical factors increasing the risk of intra-abdominal bleeding among patients with infected necrotizing pancreatitis. Additionally, massive intra-abdominal bleeding was also associated with poor prognosis.

    Abdominal pain is very common in the pediatric population (<18 years of age). Sonography is a safe modality that can often differentiate the frequently encountered causes of abdominal pain in children. This pictorial essay will discuss the sonographic findings of acute appendicitis, including the imaging appearance of a perforated appendicitis. It will also present the sonographic features of the relatively common mimics of appendicitis, such as mesenteric adenitis/gastroenteritis, intussusception, Meckel diverticulum, and ovarian torsion.

    Because young children often present to EDs with abdominal complaints, emergency physicians must have a high index of suspicion for the common abdominal emergencies that have serious sequelae. At the same time, they must realize that less serious causes of abdominal symptoms (e.g., constipation or gastroenteritis) are also seen. A gentle yet thorough and complete history and physical examination are the most important diagnostic tools for the emergency physician. Repeated examinations and observation are useful tools. Physicians should listen carefully to parents and their children, respect their concerns, and honor their complaints. Ancillary tests are inconsistent in their value in assessing these complaints. Abdominal radiographs can be normal in children with intussusception and even malrotation and early volvulus. Unlike the classic symptoms seen in adults, young children can display only lethargy or poor feeding in cases of appendicitis or can appear happy and playful between paroxysmal bouts of intussusception. The emergency physician therefore, must maintain a high index of suspicion for serious pathology in pediatric patients with abdominal complaints. Eventually, all significant abdominal emergencies reveal their true nature, and if one can be patient with the child and repeat the examinations when the child is quiet, one will be rewarded with the correct diagnosis.

    INTRODUCTION Pulmonary sequestration (PS) is an extremely rare malformation defined as a portion of lung tissue isolated from the pulmonary system. PSs are classified into intralobar type and intra-abdominal PS that represents only 2.5% of cases. There are 20 cases of PS reported in adults and only two were managed by laparoscopic approach. We report a case of intra-abdominal PS mimicking a gastroesophageal duplication cyst in an adult. Besides its rarity, this is the first intra-abdominal PS in an adult managed by an anterior laparoscopic approach. PRESENTATION OF CASE A 60-year-old female patient had had epigastric and left upper quadrant pain for several days. Physical examination was normal. Image test were consistent with a gastroesophageal duplication. The patient was taken to the operating room for laparoscopic exploration and resection. The pathological diagnosis was extralobar pulmonary sequestration. DISCUSSION Less than 20 cases of PS have been reported in adults and only two cases were managed by a lateral laparoscopic approach. In contrast to these reports, we used an anterior approach due to the GEJ suspected origin of the mass. CONCLUSION Extralobar intra-abdominal PS is an extremely rare condition during adulthood but this diagnosis should be included in the differential diagnosis of a left-sided suprarenal mass. Due to the difficulty in achieving a definitive preoperative diagnosis, surgery is recommended. Laparoscopic resection is safe and effective but careful preoperative imaging studies are recommended in order to plan the most suitable approach. PMID:24091075

    Acute pancreatitis can manifest as a benign condition with minimal abdominal pain and hyperamylasemia or can have a fulminant course, which can be life-threatening usually due to the development of infected pancreatic necrosis, and multisystem organ failure. Fortunately, 70-80% of patients with acute pancreatitis have a benign self-limiting course. The initial 24-48 hours after the initial diagnosis is usually the period that determines the subsequent course, and for many of the 20-30% of patients who subsequently have a fulminant course, this becomes apparent within this time frame. With reference to long-term outcome following acute pancreatitis, most cases recover without long-term sequelae with only a minority of cases progressing to chronic pancreatitis. In the initial management of acute pancreatitis, assessment of metabolic disturbances and systemic organ dysfunction is critical. However, the advent and continued refinement of cross-sectional imaging modalities over the past two decades has led to a prominent role for diagnostic imaging in assessing acute pancreatitis. Furthermore, these cross-sectional imaging modalities have enabled the development of diagnostic and therapeutic interventional techniques in the hands of radiologists. In this article we review the diagnostic features of acute pancreatitis, the clinical staging systems, complications and the role of imaging. The role of interventional radiology techniques in the management of acute pancreatitis will be discussed as well as potential complications associated with these treatments.

    A 65-year old man presented with acute abdominal pain and fever. The initial diagnosis was small bowel gangrene. Pathology revealed small to large abdominal vessels obliterated by cells of intravascular B-cell-lymphoma (IVL). Visceral IVL involvement is common at autopsy but rarely reported in patients with acute abdomen. The subtype of diffuse large B-cell lymphoma is a rare and aggressive malignancy, which in typical cases is characterized by cephalic or cutaneous manifestation. Few cases showed involvement of large vessels which in combination to fibrin thrombi may lead to infarction of the organ involved. Thus IVL should be considered in cases of ischemic diseases with fever of unknown origin.

    Background and Objectives: Cervical insufficiency is a difficult condition to diagnose and can lead to preterm birth, miscarriage, or perinatal infant morbidity and mortality. We conducted this retrospective case study and literature review to evaluate the safety and efficacy of robot-assisted abdominal cerclage during pregnancy. Methods: We conducted a case series and a systematic review that included patients who underwent robot-assisted abdominal cerclage during pregnancy from January 2010 through March 2016. Results: Six patients met the criteria for the case series. Median age was 34 years (range, 28–37) at the time of the procedure. In 5 cases, the indication for transabdominal cerclage was a failed vaginal cerclage in a previous pregnancy, whereas a scarred and shortened cervix caused by a previous dilatation and curettage–induced cervical laceration was the indication in the remaining case. Median operating time was 159.5 minutes (range, 124–204), and median estimated blood loss was 25 mL (range, 10–25). No surgeries were converted to laparotomies; all patients were discharged on postoperative day 1. The median gestational age at delivery was 37.5 weeks (range, 22–39). Five patients delivered between 36 and 39 weeks. No patients had chorioamnionitis or preterm premature rupture of membranes. One patient went into preterm labor at 22 weeks, and the cerclage was removed via minilaparotomy. Eight articles met the criteria for systematic review. Sixteen patients underwent robot-assisted abdominal cerclage during pregnancy. Median age was 31.5 years (range, 25–37). The major indication in most articles was previous failed transvaginal cerclage. The median gestational ages at time of procedure and delivery were 12 weeks (range, 10–15) and 37 weeks (range, 33–39), respectively. Conclusion: Robot-assisted abdominal cerclage is safe and effective during pregnancy. PMID:27904309

    Abdominal wall abscess due to Crohn's Disease used to be one of the definitive indications for operative treatment. The advent of interventional radiology, the accessibility to percutaneous drainage, and the availability of new medications raised the possibility of nonoperative treatment of this condition. The clinical presentation, treatment, and follow-up of 13 patients with abdominal wall abscesses secondary to Crohn's Disease were retrospectively reviewed. During a 10-year period (1993-2003), 13 patients with abdominal wall abscess were treated. Five patients had an anterolateral abdominal wall abscess and eight had a posterior abscess (psoas). In 11 patients, 17 drainage procedures were performed: 12 percutaneous and 5 operative. Despite initial adequate drainage and resolution of the abscess, all 13 patients eventually needed resection of the offending bowel segment, which was undertaken in 12 patients. The mean time between abscess presentation and definitive operation was 2 months. Percutaneous drainage is an attractive option in most cases of abdominal abscesses. However, in Crohn's Disease patients with an abdominal wall abscess, we found a high failure rate despite initial adequate drainage. We suggest that surgical resection of the diseased bowel segment should be the definitive therapy.

    Isolated abdominal aortic dissection is a rare clinical disease representing only 1.3% of all dissections. There are a few case series reported in the literature. The causes of this pathology can be spontaneous, iatrogenic, or traumatic. Most patients are asymptomatic and symptoms are usually abdominal or back pain, while claudication and lower limb ischemia are rare. Surgical and endovascular treatment are two valid options with acceptable results. We herein describe nine cases of symptomatic spontaneous isolated abdominal aortic dissection, out of which four successfully were treated with an endovascular approach between July 2003 and July 2013. All patients were men, smokers, symptomatic (either abdominal or back pain or lower limb ischemia), with a history of high blood pressure, with a medical history negative for concomitant aneurysmatic dilatation or previous endovascular intervention. Diagnosis of isolated abdominal aortic dissection were established by contrast-enhanced computed tomography angiography (CTA) of the thoracic and abdominal aorta. All nine patients initially underwent medical treatment. In four symptomatic cases, non-responsive to medical therapy, bare-metal stents or stent grafts were successfully positioned. All patients completed a CTA follow-up of at least 12 months, during which they remained symptom-free. Endovascular management of this condition is associated with a high rate of technical success and a low mortality; therefore, it can be considered the treatment of choice when it is feasible.

    Currently, the indications to perform reduced-intensity conditioning allogeneic hematopoietic stem cell transplant (RIC-HCT) are based on data derived mainly from large registry and single-centre retrospective studies. Thus, at the present time, there is limited direct evidence supporting the current practice in selecting patients with acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL) for RIC versus myeloablative conditioning (MAC) transplants. To determine the relationship between dose intensity of conditioning regimen and survival outcomes after allografting in AML/ALL patients, we performed a meta-analysis of 23 clinical trials reported between 1990 and 2013 involving 15,258 adult patients that compare survival outcomes after RIC-HCT versus MAC-HCT. RIC-HCT resulted in comparable <2-year and 2–6 year overall survival (OS) rates post-transplantation even though the RIC-HCT recipients were older and had more active disease than MAC-HCT recipients. The 2–6 year progression-free survival (PFS), nonrelapse mortality, acute graft-versus-host disease (GvHD) and chronic GvHD rates were reduced after RIC-HCT, but relapse rate was increased. Similar outcomes were observed regardless of disease type and status at transplantation. Odds ratio for all outcomes remained comparable with or without performing separate analyses for the year of HCT and for retrospective versus prospective studies. Among RIC-HCT recipients, survival rates were superior if patients were in CR at transplantation. Significant inter-study heterogeneity for aGvHD data and publication bias for PFS data were observed. This meta-analysis showed no OS benefit of MAC-HCT over RIC-HCT across the entire cohort of patients suggesting that RIC-HCT could be an effective therapeutic option for AML/ALL patients who are ineligible for MAC-HCT and CR status is preferred before RIC-HCT.

    Clinical palpation of a pulsating abdominal mass alerts the clinician to the presence of a possible abdominal aortic aneurysm (AAA). Generally an arterial aneurysm is defined as a localized arterial dilatation ≥50% greater than the normal diameter. Imaging studies are important in diagnosing the cause of a pulsatile abdominal mass and, if an AAA is found, in determining its size and involvement of abdominal branches. Ultrasound (US) is the initial imaging modality of choice when a pulsatile abdominal mass is present. Noncontrast computed tomography (CT) may be substituted in patients for whom US is not suitable. When aneurysms have reached the size threshold for intervention or are clinically symptomatic, contrast-enhanced multidetector CT angiography (CTA) is the best diagnostic and preintervention planning study, accurately delineating the location, size, and extent of aneurysm and the involvement of branch vessels. Magnetic resonance angiography (MRA) may be substituted if CT cannot be performed. Catheter arteriography has some utility in patients with significant contraindications to both CTA and MRA. The American College of Radiology Appropriateness Criteria(®) are evidence-based guidelines for specific clinical conditions that are reviewed every 2 years by a multidisciplinary expert panel. The guideline development and review include an extensive analysis of current medical literature from peer reviewed journals and the application of a well-established consensus methodology (modified Delphi) to rate the appropriateness of imaging and treatment procedures by the panel. In those instances where evidence is lacking or not definitive, expert opinion may be used to recommend imaging or treatment.

    It is shown, that tactics of treatment of acute marrow failure of radiant etiology is based, first of all, on measures of supporting, replaceable and stimulating therapy. The modern means, used for prophylactic and treatment of infectious complications, are resulted. Opportunities and restrictions of transfusion of donor thrombocytes and granulocytes, erythrocytes and chilled plasma are described. Therapeutic efficiency of transplantation of a bone marrow, cells of embryonic liver and stem cells of peripheral or umbilical cord blood is analyzed. It is shown, that the greatest prospects in perfection of the specialized medical aid at acute radiation syndrome are connected to complex application of interleukin-1beta, interleukin-3, granulocyte or granulocyte/macrophage colony stimulated factor, thrombopoietin and others cytokines.

    Abdominal pregnancies are the implantation of gestation in some of the abdominal structures. This kind of pregnancies represents sevenfold maternal death risk than tubarian ectopic pregnancies, and 90-fold death risk than normal ones. Previous cases have erroneously reported as abscess in Douglas punch, and frequently result in obitus or postnatal deaths. We report a case of a patient with 27 years old, and diagnosis of 25.2 weeks of pregnancy, prior placenta and anhidramnios, referred due to difficult in uterine contour delimitation, easy palpation of fetal parts, cephalic pole in left hypochondrious and presence of mass in hypogastria, no delimitations, pain with mobilization, no transvaginal bleed and fetal movements. Interruption of pregnancy is decided by virtue of severe oligohidramnios, retardation in fetal intrabdominal growth, and recurrent maternal abdominal pain. Surgical intervention was carried out for resolution of the obstetrical event, in which was found ectopic abdominal pregnancy with bed placental in right uterine horn that corresponded to a pregnancy of 30 weeks of gestation. Abdominal pregnancy is still a challenge for obstetrics due to its diagnosis and treatment. Early diagnosis is oriented to prevent an intrabdominal hemorrhage that is the main maternal cause of mortality.

    Objective To evaluate the clinical course and respiratory parameters of mechanically ventilated children with cancer suffering from sepsis-related acute respiratory distress syndrome. Methods This 2-year prospective, longitudinal, observational cohort study enrolled 29 children and adolescents. Clinical data, measurements of blood gases and ventilation parameters were collected at four different time points. Fluctuations between measurements as well as differences in estimated means were analyzed by linear mixed models in which death within 28 days from the onset of acute respiratory distress syndrome was the primary endpoint. Results There were 17 deaths within 28 days of acute respiratory distress syndrome onset and another 7 between 29 - 60 days. Only 5 patients survived for more than 60 days. Nine (31%) patients died as a direct consequence of refractory hypoxemia, and the others died of multiple organ failure and catecholamine-refractory shock. In 66% of the measurements, the tidal volume required to obtain oxygen saturation equal to or above 90% was greater than 7mL/kg. The estimated means of dynamic compliance were low and were similar for survivors and non-survivors but with a negative slope between the first and final measurements, accompanied by a negative slope of the tidal volume for non-survivors. Non-survivors were significantly more hypoxemic, with PaO2/FiO2 ratios showing lower estimated means and a negative slope along the four measurements. Peak, expiratory and mean airway pressures showed positive slopes in the non-survivors, who also had more metabolic acidosis. Conclusions In most of our children with cancer, sepsis and acute respiratory distress syndrome progressed with deteriorating ventilation indexes and escalating organic dysfunction, making this triad nearly fatal in children.

    Purpose: Hematopoietic stem cell transplantation (HSCT) is the mainstay of treatment for adults with acute leukemia. Total body irradiation (TBI) remains an important part of the conditioning regimen for HCST. For those patients unable to tolerate myeloablative TBI (mTBI), reduced intensity TBI (riTBI) is commonly used. In this study we compared outcomes of patients undergoing mTBI with those of patients undergoing riTBI in our institution. Methods and Materials: We performed a retrospective review of all patients with acute leukemia who underwent TBI-based conditioning, using a prospectively acquired database of HSCT patients treated at our institution. Patient data including details of the transplantation procedure, disease status, Karnofsky performance status (KPS), response rates, toxicity, survival time, and time to progression were extracted. Patient outcomes for various radiation therapy regimens were examined. Descriptive statistical analysis was performed. Results: Between June 1985 and July 2012, 226 patients with acute leukemia underwent TBI as conditioning for HSCT. Of those patients, 180 had full radiation therapy data available; 83 had acute lymphoblastic leukemia and 94 had acute myelogenous leukemia; 45 patients received riTBI, and 135 received mTBI. Median overall survival (OS) was 13.7 months. Median relapse-free survival (RFS) for all patients was 10.2 months. Controlling for age, sex, KPS, disease status, and diagnosis, there were no significant differences in OS or RFS between patients who underwent riTBI and those who underwent mTBI (P=.402, P=.499, respectively). Median length of hospital stay was shorter for patients who received riTBI than for those who received mTBI (16 days vs 23 days, respectively; P<.001), and intensive care unit admissions were less frequent following riTBI than mTBI (2.22% vs 12.69%, respectively, P=.043). Nonrelapse survival rates were also similar (P=.186). Conclusions: No differences in OS or RFS were seen between

    Experience-produced deficits in trace conditioning and context conditioning have been useful tools for examining the role of the hippocampus in learning. It has also been suggested that learning in these tasks is especially vulnerable to neurotoxic effects of alcohol during key developmental periods such as adolescence. In five experiments we systematically examined the presence and source of age-dependent vulnerability to the memory-disrupting effects of acute ethanol in trace conditioning and contextual fear conditioning. In Experiment 1a pre-training ethanol disrupted trace conditioning more strongly in adolescent (postnatal day, PD30-35) than adult rats (PD65-75). In Experiment 1b when pre-training ethanol was accompanied by pre-test ethanol no deficit in trace conditioning was observed in adolescents, suggesting that state-dependent retrieval failure mediated ethanol's disruption of trace conditioning at this age. Experiment 2a and b examined the effect of ethanol pretreatment on context conditioning. Here, adult but not adolescent rats were impaired in conditioned freezing to context cues. Experiment 2c explored state-dependency of this effect. Pre-training ethanol continued to disrupt context conditioning in adults even when ethanol was also administered prior to test. Collectively these findings reveal clear age-dependent and task-dependent vulnerabilities in ethanol's disruptive effects on hippocampus-dependent memory. Adolescents were more disrupted by ethanol in trace conditioning than adults, and adults were more disrupted by ethanol in context conditioning than adolescents. We suggest that adolescents may be more susceptible to changes in internal state (state-dependent retrieval failure) than adults and that ethanol disrupted performance in trace and context conditioning through different mechanisms. Relevance of these findings to theories of hippocampus function is discussed.

    Gastric volvulus is a rare complication of diaphragmatic rupture. We report the case of an 82-year-old man who presented following an out-of-hospital cardiac arrest. Chest radiography and thoracic computed tomography revealed an acute gastric volvulus and a chronic diaphragmatic hernia containing transverse colon and abdominal viscera. He had complained of retching and associated epigastric pain prior to collapse, and had sustained a motorcycle accident approximately 60 years earlier. Insertion of a nasogastric tube was unsuccessful (completing Borchardt’s diagnostic triad) and his condition prevented both operative and endoscopic reduction of his volvulus. He died soon afterwards. PMID:25245717

    [Purpose] The aim of this study was to clarify physical parameters affecting the tidal volume during expiratory abdominal compression in patients with prolonged tracheostomy mechanical ventilation. [Methods] Eighteen patients with prolonged mechanical ventilation were included in this study. Expiratory abdominal compression was performed on patients lying in a supine position. The abdomen above the navel was vertically compressed in synchronization with expiration and released with inspiration. We measured the tidal volume during expiratory abdominal compression. [Results] The mean tidal volume during expiratory abdominal compression was higher than that at rest (430.6 ± 127.1 mL vs. 344.0 ± 94.3 mL). The tidal volume during expiratory abdominal compression was correlated with weight, days of ventilator support, dynamic compliance and abdominal expansion. Stepwise multiple regression analysis revealed that weight (β = 0.499), dynamic compliance (β = 0.387), and abdominal expansion (β = 0.365) were factors contributing to the tidal volume during expiratory abdominal compression. [Conclusion] Expiratory abdominal compression increased the tidal volume in patients with prolonged tracheostomy mechanical ventilation. The tidal volume during expiratory abdominal compression was influenced by each of the pulmonary conditions and the physical characteristics. PMID:26311947

    Obesity is associated with the metabolic syndrome. However, not all obese individuals have cardiovascular risk factors (CVRF). It is not clear how many abdominally obese individuals are free of CVRF and what distinguishes them from the group of obese individuals with CVRF. In this study, we aimed to assess the associated factors and prevalence of abdominal obesity without CVRF. In our cross-sectional analysis, we included n = 4244 subjects from the Study of Health in Pomerania (SHIP), a population-based study and n = 6671 subjects from the Diabetes Cardiovascular Risk-Evaluation: Targets and Essential Data for Commitment of Treatment (DETECT) study, a representative primary care study in Germany. We defined abdominal obesity by waist-to-height ratio (WHtR) of 0.5 or greater. We assessed how many subjects with abdominal obesity had CVRF based on the definition of the metabolic syndrome. We analysed which conditions were associated with the absence of CVRF in abdominal obesity. In SHIP and DETECT, 2652 (62.5%) and 5126 (76.8%) subjects had a WHtR ≥ 0.5. Among those with a WHtR ≥ 0.5, 9.0% and 13.8% were free of CVRF and 49.9% and 52.7% had at least two CVRF in SHIP and DETECT, respectively. In both studies, after backward elimination, age, male sex, body mass index and high liver enzymes and unemployment were consistently inversely associated with the absence of CVRF. Among abdominally obese subjects, the prevalence of metabolically healthy subjects is low. Conditions consistently associated with the absence of CVRF in abdominal obesity are younger age, female sex, low BMI, and normal liver enzymes, the latter likely reflecting the absence of steatohepatitis.

  7. Recovery after abdominal wall reconstruction.

    Incisional hernia is a common long-term complication to abdominal surgery, occurring in more than 20% of all patients. Some of these hernias become giant and affect patients in several ways. This patient group often experiences pain, decreased perceived body image, and loss of physical function, which results in a need for surgical repair of the giant hernia, known as abdominal wall reconstruction. In the current thesis, patients with a giant hernia were examined to achieve a better understanding of their physical and psychological function before and after abdominal wall reconstruction. Study I was a systematic review of the existing standardized methods for assessing quality of life after incisional hernia repair. After a systematic search in the electronic databases Embase and PubMed, a total of 26 studies using standardized measures for assessment of quality of life after incisional hernia repair were found. The most commonly used questionnaire was the generic Short-Form 36, which assesses overall health-related quality of life, addressing both physical and mental health. The second-most common questionnaire was the Carolinas Comfort Scale, which is a disease specific questionnaire addressing pain, movement limitation and mesh sensation in relation to a current or previous hernia. In total, eight different questionnaires were used at varying time points in the 26 studies. In conclusion, standardization of timing and method of quality of life assessment after incisional hernia repair was lacking. Study II was a case-control study of the effects of an enhanced recovery after surgery pathway for patients undergoing abdominal wall reconstruction for a giant hernia. Sixteen consecutive patients were included prospectively after the implementation of a new enhanced recovery after surgery pathway at the Digestive Disease Center, Bispebjerg Hospital, and compared to a control group of 16 patients included retrospectively in the period immediately prior to the

    The purpose of this study was to determine if a single dose of radiation to the rat abdomen leads to bacterial translocation into the mesenteric lymph nodes (MLN). A second issue addressed was whether translocation correlates with anatomic damage to the mucosa. The radiated group (1100 cGy) which received anesthesia also was compared with a control group and a third group which received anesthesia alone but no abdominal radiation. Abdominal radiation lead to 100% positive cultures of MLN between 12 hr and 4 days postradiation. Bacterial translocation was almost nonexistent in the control and anesthesia group. Signs of inflammation and ulceration of the intestinal mucosa were not seen until Day 3 postradiation. Mucosal damage was maximal by Day 4. Bacterial translocation onto the MLN after a single dose of abdominal radiation was not apparently dependent on anatomical, histologic damage of the mucosa.

    The bowel and the mesentery represent the third most frequently involved structures in blunt abdominal trauma after the liver and the spleen. Clinical assessment alone in patients with suspected intestinal and/or mesenteric injury from blunt abdominal trauma is associated with unacceptable diagnostic delays. Multi-detector computed tomography, thanks to its high spatial, time and contrast resolutions, allows a prompt identification and proper classification of such conditions. The radiologist, in fact, is asked not only to identify the signs of trauma but also to provide an indication of their clinical significance, suggesting the chance of conservative treatment in the cases of mild and moderate, non-complicated or self-limiting injuries and focusing on life-threatening conditions which may benefit from immediate surgical or interventional procedures. Specific and non-specific CT signs of bowel and mesenteric injuries from blunt abdominal trauma are reviewed in this paper.

    Abdominal bloating is a very common and troublesome symptom of all ages, but it has not been fully understood to date. Bloating is usually associated with functional gastrointestinal disorders or organic diseases, but it may also appear alone. The pathophysiology of bloating remains ambiguous, although some evidences support the potential mechanisms, including gut hypersensitivity, impaired gas handling, altered gut microbiota, and abnormal abdominal-phrenic reflexes. Owing to the insufficient understanding of these mechanisms, the available therapeutic options are limited. However, medical treatment with some prokinetics, rifaximin, lubiprostone and linaclotide could be considered in the treatment of bloating. In addition, dietary intervention is important in relieving symptom in patients with bloating. PMID:24199004

    The authors report the case of a 93-year old woman referred to the emergency department and presenting with an intestinal obstruction. Abdominal CT reveals a biliary ileus caused by the migration and the impaction of a 3 cm gallstone in the small bowel. Surgical treatment by enterolithotomy was successful. In over 90% of cases, gallstone ileus is a complication of cholelithiasis and accounts for 25% of intestinal obstruction in patients over 65 years. To reduce morbidity and mortality, early diagnosis and prompt treatment are essential. Abdominal CT-scan is the gold standard technique.

    Metabolic syndrome is associated with abdominal obesity, blood lipid disorders, inflammation, insulin resistance or full-blown diabetes, and increased risk of developing cardiovascular disease. Proposed criteria for identifying patients with metabolic syndrome have contributed greatly to preventive medicine, but the value of metabolic syndrome as a scientific concept remains controversial. The presence of metabolic syndrome alone cannot predict global cardiovascular disease risk. But abdominal obesity - the most prevalent manifestation of metabolic syndrome - is a marker of 'dysfunctional adipose tissue', and is of central importance in clinical diagnosis. Better risk assessment algorithms are needed to quantify diabetes and cardiovascular disease risk on a global scale.

    Abdominal surgery in foals under 30 days old has become more common with improved neonatal care. Early recognition of a foal at risk and better nursing care have increased the survival rates of foals that require neonatal care. The success of improved neonatal care also has increased the need for accurate diagnosis and treatment of gastrointestinal, umbilical, and bladder disorders in these foals. This chapter focuses on the early and accurate diagnosis of specific disorders that require abdominal exploratory surgery and the specific treatment considerations and prognosis for these disorders.

    The acute toxicity of physically and chemically dispersed crude oil and the dispersant Corexit 9500 were evaluated for key Arctic species. The copepod Calanus glacialis, juvenile Arctic cod (Boreogadus saida), and larval sculpin (Myoxocephalus sp.) were tested under conditions representative of the Beaufort and Chukchi Seas during the ice-free season. The toxicity of 3 water-accommodated fractions (WAF) of Alaska North Slope crude oil was examined with spiked, declining exposures. A dispersant-only test was conducted with the copepod C. glacialis. Each preparation with oil (WAF, breaking wave WAF [BWWAF], and chemically enhanced WAF [CEWAF]) produced distinct suites of hydrocarbon constituents; the total concentrations of oil were lowest in WAF and highest in CEWAF preparations. The relative sensitivity for the different species and age classes was similar within each WAF type. Median lethal concentration values based on total petroleum hydrocarbons ranged from 1.6 mg/L to 4.0 mg/L for WAF and BWWAF treatments and from 22 mg/L to 62 mg/L for CEWAF. For Corexit 9500 exposures, median lethal concentration values ranged from 17 mg/L to 50 mg/L. The differences in the relative toxicity among the accommodated fractions indicated that the majority of petroleum hydrocarbons in the CEWAF are in less acutely toxic forms than the components that dominate the WAF or BWWAF. Further evaluation showed that the parent polycyclic aromatic hydrocarbon compounds, specifically naphthalene, were highly correlated to acute toxicity.

    Aim: Brain-derived neurotrophic factor (BDNF) plays an important role in learning and memory in multiple brain areas. In the present study, we investigated the roles of BDNF in aversive memories associated with conditioned drug withdrawal in acute morphine-dependent rats. Methods: Conditioned place aversion (CPA) was induced in male SD rats exposed to a single dose of morphine (10 mg/kg, sc) followed by naloxone (0.3 mg/kg, sc). In some rats, BDNF receptor antagonist K252a (8.5 ng per side) or BDNF scavenger TrkB-FC (0.65 μg per side) was bilaterally microinjected into amygdala before naloxone injection. BDNF mRNA and protein expression levels in amygdala were detected after the behavior testing. Results: CPA behavior was induced in rats by the naloxone-precipitated morphine withdrawal, which was accompanied by significantly increased levels of BDNF mRNA and protein in the amygdala. Bilateral microinjection of TrkB-FC or K252a into the amygdala completely blocked CPA behavior in the rats. Conclusion: Formation of aversive memories associated with conditioned drug withdrawal in acute morphine-dependent rats requires BDNF expression in the amygdala. PMID:26567727

    Here, we report on a case of acute phlegmonous gastritis (PG) complicated by delayed perforation. A 51-year-old woman presented with severe abdominal pain and septic shock symptoms. A computed tomography scan showed diffuse thickening of the gastric wall and distention with peritoneal fluid. Although we did not find definite evidence of free air on the computed tomography (CT) scan, the patient's clinical condition suggested diffuse peritonitis requiring surgical intervention. Exploratory laparotomy revealed a thickened gastric wall with suppurative intraperitoneal fluid in which Streptococcus pyogenes grew. There was no evidence of gastric or duodenal perforation. No further operation was performed at that time. The patient was conservatively treated with antibiotics and proton pump inhibitor, and her condition improved. However, she experienced abdominal and flank pain again on postoperative day 10. CT and esophagogastroduodenoscopy showed a large gastric ulcer with perforation. Unfortunately, although the CT showed further improvement in the thickening of the stomach and the mucosal defect, the patient's condition did not recover until a week later, and an esophagogastroduodenoscopy taken on postoperative day 30 showed suspected gastric submucosal dissection. We performed total gastrectomy as a second operation, and the patient recovered without major complications. A pathological examination revealed a multifocal ulceration and necrosis from the mucosa to the serosa with perforation.

Racemic sotalol (40 mg kg−1) was administered to healthy, acutely (interferonα 2a-induced) and chronically (Mycobacterium butyricum-induced adjuvant arthritis) inflamed male Sprague-Dawley rats (n=4 – 6/group). Another group of interferon-treated rats received 3 mg kg−1 of anti-TNF antibody infliximab. Electrocardiogram (ECG) recorded and plasma sotalol concentration monitored for 6 h. The study was repeated in acutely inflamed rats following administration of stereochemically pure individual sotalol enantiomers [40 mg kg−1 S (potassium channel blocker) or 20 mg kg−1 R (β-adrenergic/potassium channel blocker)]. Chronic arthritis was readily evident. Acute arthritis was associated with elevated segmented neutrophils and increased plasma nitrite and tumour necrosis factor (TNF) concentrations. Sotalol affected ECG in all rats. In both inflamed groups, however, response to sotalol in prolongation of QT interval (potassium channel sensitivity) was reduced. The effect of PR interval (β-adrenergic activity) was also reduced following administration of the racemate and R-enantiomer. No significant differences in pharmacokinetics were observed between control and inflamed rats. Infliximab reduced nitrite and TNF concentrations and reversed the effect of acute inflammation on both PR and QT intervals. The reduced electrocardiographic responses to sotalol is likely due to the influence of inflammation on the action of the drug on both β-adrenergic and potassium channel receptors secondary to over-expression of pro-inflammatory cytokines and/or nitric oxide. Our observation may have therapeutic consequences in all conditions where inflammatory mediators are increased. PMID:11350865

    Objectives: To investigate the effect of non-elastic/elastic abdominal binders on intra-vesical pressure (IVP), physiological functions, and clinical outcomes in laparotomy patients at the perioperative stage. Methods: This prospective study was conducted from May to October 2014 at the Trauma Surgery Department, Daping Hospital, Chongqing, China. Laparotomy patients were randomly divided into non-elastic abdominal binder group (28 patients), and elastic abdominal binder group (29 patients). Binders were applied for 14 days following the operation, or until discharge. Demographic information, Sequential Organ Failure Assessment (SOFA) and Acute Physiology and Chronic Health Evaluation II (APACHE-II) scores (prior to the operation, on the first day after operation, the day IVP measurement was stopped, and one day before discharge), and outcomes were recorded. The IVP was measured before the operation to postoperative day 7. Results: There were no significant differences in the demographic information, outcomes, SOFA or APACHE-II scores between the 2 groups. Initial out-of-bed mobilization occurred earlier in the elastic binder group (3.2 ± 2.0 versus 5.0 ± 3.7 days, p=0.028). A greater increase in IVP was observed in the non-elastic binder group than in the elastic binder group (2.9 ± 1.1 versus 1.1 ± 0.7 mm Hg, p=0.000). Conclusion: Elastic binders have relatively little effect on IVP and are more helpful at promoting postoperative recovery than non-elastic binders. Therefore, elastic binders are more suitable for clinical use. PMID:26739977

    Current therapies for acute myeloid leukemia (AML), failing induction, are rarely effective. We report our experience in 4 patients with AML who received 16 Gy TBI prior to allogeneic hematopoietic cell transplantation (alloHCT), between June 2010 and May 2011. Patients were 20 to 55 years of age, 2 with relapsed disease and 2 with AML failing induction. An HLA-matched graft from related or unrelated donor was infused on day 0. All but one, who received a CD34+-selected graft, received methotrexate and tacrolimus +/− antithymocyte globulin, as GVHD prophylaxis. The other patient received tacrolimus alone. Neutrophil and platelet engraftment occurred at a median of 18 and 14 days, respectively. Patients were discharged at a median of 28 days. There were no unexpected toxicities in the first 30 days. One patient had cytomegalovirus (CMV) viremia and anorexia, at two months. One patient had grade 2 acute GVHD of the skin. One patient developed chronic GVHD of the eyes, mouth, skin, joints, and lung at 4 months. Two patients died from relapse of their leukemia at days 65 and 125. Two patients remain in remission beyond day 1500. 16 Gy TBI followed by an alloHCT for AML, failing induction, is feasible and tolerable. PMID:27957357

    The visceral insular cortex (VIC) has previously been shown to play a critical role during acute nausea-induced conditioned gaping in rats. Specifically, localized administration of the conventional anti-emetic, ondansetron or the synthetic cannabinoid, HU210, interferes with the establishment of conditioned gaping, likely by reducing the effects of an illness-inducing treatment. However the precise role of the VIC in endocannabinoid-suppression of nausea remains unknown; thus we investigated the potential of localized intra-VIC endocannabinoid administration to interfere with acute nausea-induced conditioned gaping behavior in male Sprague-Dawley rats. Animals received an intraoral infusion of saccharin (0.1%) followed by intra-VIC exogenous N-arachidonoylethanolamide (AEA; 0.4, 4 μg) or 2-arachidonoylglycerol (2-AG; 0.5, 1 μg), and were subsequently injected with nausea-inducing LiCl (0.15M) 15 min later. Bilateral intra-VIC infusions of 2-AG (1 μg, but not 0.5 μg) dose-dependently suppressed conditioned gaping, whereas exogenous AEA was without effect. Interestingly, 2-AG reduced conditioned gaping despite additional pretreatment with the selective cannabinoid receptor type 1 (CB1) antagonist, AM-251; however, concomitant pretreatment with the cyclooxygenase inhibitor, indomethacin (0.5 μg), blocked the suppressive effects of intra-VIC 2-AG. These findings suggest that the modulatory role of the endocannabinoid system during nausea is driven largely by the endocannabinoid, 2-AG, and that its anti-nausea effects may be partly independent of CB1-receptor signaling through metabolic products of the endocannabinoid system.

    This article discusses the range of manifestations of tuberculosis (TB) of the abdomen, including involvement of the gastrointestinal tract, the peritoneum, mesentery, omentum, abdominal lymph nodes, solid abdominal organs, the genital system and the abdominal aorta. Abdominal TB is a diagnostic challenge, particularly when pulmonary TB is absent. It may mimic many other abdominal diseases, both clinically and radiologically. An early correct diagnosis, however, is important in order to ensure proper treatment and a favorable outcome. Modern imaging is a cornerstone in the early diagnosis of abdominal TB and may prevent unnecessary morbidity and mortality. Generally, CT appears to be the imaging modality of choice in the detection and assessment of abdominal tuberculosis, other than gastrointestinal TB. Barium studies remain superior for demonstrating mucosal intestinal lesions. Ultrasound may be used for follow-up to monitor therapy response. The diagnosis of abdominal TB should be considered if suggestive imaging findings are found in patients with a high index of suspicion.

    This study analysed the outcome of 267 patients with relapse/refractory acute myeloid leukaemia (AML) who received sequential chemotherapy including fludarabine, cytarabine and amsacrine followed by reduced-intensity conditioning (RIC) and allogeneic haematopoietic stem cell transplantation (HSCT). The transplants in 77 patients were from matched sibling donors (MSDs) and those in 190 patients were from matched unrelated donors. Most patients (94·3%) were given anti-T-cell antibodies. The incidence of acute graft-versus-host disease (GVHD) of grades II-IV was 32·1% and that of chronic GVHD was 30·2%. The 3-year probability of non-relapse mortality (NRM) was 25·9%, that of relapse was 48·5%, that of GVHD-free and relapse-free survival (GRFS) was 17·8% and that of leukaemia-free survival (LFS) was 25·6%. In multivariate analysis, unrelated donor recipients more frequently had acute GVHD of grades II-IV [hazard ratio (HR) = 1·98, P = 0·017] and suffered less relapses (HR = 0·62, P = 0·01) than MSD recipients. Treatment with anti-T-cell antibodies reduced NRM (HR = 0·35, P = 0·01) and improved survival (HR = 0·49, P = 0·01), GRFS (HR = 0·37, P = 0·0004) and LFS (HR = 0·46, P = 0·005). Thus, sequential chemotherapy followed by RIC HSCT and use of anti-T-cell antibodies seems promising in patients with refractory AML.

    Acute myeloid leukemia with monosomal karyotype (MK AML) carries a very poor prognosis, even after allogeneic stem cell transplantation (SCT). However, SCT remains the only curative option in this high-risk population. Because myeloablative conditioning regimen (MAC) is associated with less relapse, we hypothesized that more intensive conditioning regimen might be beneficial for MK AML patients. We reviewed 303 patients over age 45 diagnosed with either de novo or secondary MK AML. One hundred and five patients received a MAC and 198 a reduced-intensity conditioning (RIC). The median age at SCT was 57-year-old, significantly lower in the MAC (53-year-old) than in the RIC group (59-year-old). The median follow-up was 42 months (range, 3 - 156 months). The 3-year overall survival (OS), leukemia-free survival (LFS), and relapse rate (RR) were not significantly different between both groups with overall values of 34%, 29%, and 51%, respectively. On the contrary, the 3-year nonrelapse mortality (NRM) was significantly higher in MAC recipients (28%) compared with RIC patients (16%, P = 0.004). The incidence of Grades II to IV acute graft-versus-host disease (GvHD) was significantly higher after a MAC (30.5%) than after a RIC (19.3%, P = 0.02). That of chronic GvHD was comparable between both groups (35%) and did not impact on LFS. Interestingly, within our MK AML cohort, hypodiploidy was significantly associated with worse outcomes. Due to reduced toxicity and comparable OS, LFS, and RR, RIC appears as a good transplant option in the very high-risk population, including older patients, diagnosed with MK AML.

    The antineoplastic effect of allogeneic stem cell transplantation after reduced-intensity conditioning (RIC) relies on the graft-versus-tumour (GvT) reaction. GvT is closely linked to the development of graft-versus-host disease (GvHD). The incidence of acute GvHD after RIC seems lower than after myeloablative conditioning (MAC), whereas the incidence of chronic GvHD after RIC seems similar to after MAC. The results of RIC for acute myeloid leukaemia show a non-relapse mortality of approximately 15% at one year, a relapse incidence of approximately 40% after a median of 4-6 months, translating into overall and disease-free survival rates of 40-60%. The factors associated with improved outcome in most studies are the stage of the disease at transplantation, age and the development of chronic GvHD (and thus GvT). In a recent report, chronic GvHD was the most important factor associated with prolonged survival. Future efforts should be directed at aiming to decrease relapse rates. For this purpose, an adequate identification of high-risk patients, close monitoring of minimal residual disease after the procedure, and the use of antineoplastic drugs or immunotherapy may be of help.

    Superior Mesenteric Artery (SMA) syndrome is a condition in which the duodenum becomes compressed between the SMA and the aorta, resulting in bowel obstruction which subsequently compresses surrounding structures. Pressure on the inferior vena cava (IVC) and aorta decreases cardiac output which compromises distal blood flow, resulting in abdominal compartment syndrome with ischemia and renal failure. A 15-year-old male with SMA syndrome presented with 12 hours of pain, a distended, rigid abdomen, mottled skin below the waist, and decreased motor and sensory function in the lower extremities. Exploratory laparotomy revealed ischemic small bowel and stomach with abdominal compartment syndrome. Despite decompression, the patient arrested from hyperkalemia following reperfusion.

    The possible involvement of histone deacetylase (HDAC) in regulation of ROS content in the tissue culture of Arabidopsis thaliana under normal conditions and under development of acute osmotic stress was studied by using inhibition assay with application of trichostatin A (TSA). It was found that in the tissue culture grown under normal conditions a decrease in HDAC activity by means of TSA led to increase of the ROS content. Similar but more pronounced alterations occurred under stress. At the same time an increase in histone acetyltransferase (HAT) activity was also observed. The possible mechanisms of HDAC and HAT participation in regulation of ROS content by changes in expression of genes that are responsible for ROS production and antioxidant activity are discussed.

    The Okaloosa darter, Etheostoma okaloosae, is found exclusively in the Rocky and Boggy Bayou stream systems entering Choctawhatchee Bay, Florida. Due to its limited range and habitat degradation, E. okaloosae was added to the List of Endangered Species in 1973. The Air Force controls several active test areas situated near streams known to contain Okaloosa darters. The possible release and deposition of strong acids such as hydrochloric acid and hydrofluoric acid to stream surface water during some testing activities has raised concerns that the Okaloosa darter population may be adversely affected by episodic pH depression as a result of testing activities. To evaluate the sensitivity of the Okaloosa darter to pH depression, acute toxicity tests using a closely related species, E. edwini, were conducted. Ninety-six hour and 200 min acute pH depression flow-through toxicity tests were performed with surface water collected from the Rocky Bayou stream system. The 96 h test was conducted using six concentrations held at constant pH throughout the duration of the exposure. The 200 min test used an episodic exposure; pH in the exposure chambers were initially dropped and allowed to return to normal. Mortality data obtained during the studies were used to determine the pH depression necessary to cause 50% mortality (LC50) in each scenario. The 96 h and 200 min LC50 values are, respectively, 3.79 and 2.99 s.u. The 200 min LC50 calculations are based on the lowest achieved pH in each exposure during the test. The results of these tests are part of an effort by the Air Force to make risk-based management decision regarding testing activities.

    Marfan syndrome (MFS) is an autosomal dominant connective tissue disease associated with acute aortic dissection (AAD). We used 2 large registries that include patients with MFS to investigate possible trends in the chronobiology of AAD in MFS. We queried the International Registry of Acute Aortic Dissection (IRAD) and the Genetically Triggered Thoracic Aortic Aneurysms and Cardiovascular Conditions (GenTAC) registry to extract data on all patients with MFS who had suffered an AAD. The group included 257 patients with MFS who suffered an AAD from 1980 to 2012. The chi-square tests were used for statistical testing. Mean subject age at time of AAD was 38 years, and 61% of subjects were men. AAD was more likely in the winter/spring season (November to April) than the other half of the year (57% vs 43%, p = 0.05). Dissections were significantly more likely to occur during the daytime hours, with 65% of dissections occurring from 6 a.m. to 6 p.m. (p = 0.001). Men were more likely to dissect during the daytime hours (6 a.m. to 6 p.m.) than women (74% vs 51%, p = 0.01). These insights offer a glimpse of the times of greatest vulnerability for patients with MFS who suffer from this catastrophic event. In conclusion, the chronobiology of AAD in MFS reflects that of AAD in the general population.

    Computed tomographic (CT) angiography (CTA) has become the preferred imaging test of choice for various aortic conditions because of its excellent spatial resolution, rapid image acquisition, and its wide availability. CTA provides a robust tool for planning aortic interventions and diagnosing acute and chronic vascular diseases in the abdomen. CTA is the standard for imaging aneurysms before intervention and evaluating the aorta in the acute setting to assess traumatic injury, dissection, and aneurysm rupture. Knowledge of the imaging features of these disease processes, inflammatory vasculitides, and occlusive atherosclerotic disease is essential for guiding surgical and medical management of patients.

    Scrub typhus is a mite-borne infectious disease caused by Orientia tsutsugamushi, which presents as an acute febrile illness with headache, myalgia, breathlessness, and an eschar, a pathognomonic sign, in a varying proportion of patients. However, this illness can present unusually with fever and severe abdominal pain mimicking acute abdomen. A careful search for an eschar in all patients with an acute febrile illness would provide a valuable diagnostic clue and avoid unnecessary investigations and surgical exploration.

    In children with no prior history of abdominal surgery and no signs of intussusception or incarcerated inguinal hernia, mechanical ileus may have a congenital cause such as malrotation with volvulus or a persistent omphalomesenteric duct. Acquired causes include sigmoid volvulus. We present two cases of mechanical ileus in children. The first case involved a 6-year-old boy who presented with acute abdominal pain and vomiting. An emergency laparotomy was performed, with resection of the omphalomesenteric duct. Recovery was uneventful. The other case concerned a 9-year-old boy who presented with increasing abdominal pain, bilious vomiting and general clinical deterioration. An emergency laparotomy was performed, revealing malrotation with volvulus and intestinal ischaemia. Children with no prior abdominal history who present with symptoms that may be caused by mechanical obstruction should be managed with a view to surgery and without delay, in order to prevent a catastrophic outcome resulting from a congenital or acquired mechanical obstruction.

    Term, live abdominal pregnancy secondary to rupture of a uterine rudimentary horn is a rare condition. Pregnancies conceived in the rudimentary horn of the uterus usually rupture during early gestation and present as a catastrophic event. However, rarely, after rupture of the uterine horn the foetus may continue to grow in the abdominal cavity and reach term gestation. A primigravida with a term pregnancy was referred to our centre for caesarean section with ultrasonography findings of transverse lie and placenta previa. During surgery, a live baby was extracted from the abdominal cavity, revealing a bicornuate uterus with rupture of the rudimentary horn. The early peroperative diagnosis and prompt control of the bleeding with excision of the rudimentary horn and transfusion of multiple blood products saved the patient’s life. The case is presented for its rarity and to highlight the importance of a high index of suspicion in cases presenting with abnormal foetal presentation. PMID:27904431

    Purpose: To analyze the effectiveness of the American Red Cross Emergency Response Course (ARC ERC) in improving decision‐making skills of physical therapists (PTs) and third semester clinical doctorate student physical therapists (SPTs) when assessing acute sports injuries and medical conditions. Methods: An existing questionnaire was modified, with permission from the original authors of the instrument. The questionnaire was administered to PTs and SPTs before the start of and immediately after the completion of 5 different ARC ERCs. The overall percentages of “Appropriate” responses for the 17 case scenarios were calculated for each participant for the pre‐and post‐tests. Participants also rated their perceived level of preparedness for managing various conditions using a 5‐point Likert Scale (ranging from Prepared to Unprepared). The overall percentage of “Prepared/Somewhat Prepared” responses for the 16 medical conditions was calculated for each participant for the pre‐and post‐tests. In addition, mean Likert scale scores were calculated for level of perceived preparedness for each of the 16 medical conditions. Paired t‐tests, calculated with SPSS 20.0, were used to analyze the data. Results: 37 of 37 (100.0%) of eligible PTs and 45 of 48 (93.8%) of eligible SPTs completed the pre‐ and post‐test questionnaires. The percentage of “Appropriate” responses for all 17 cases in the aggregate (PTs: 76.8% pre‐test, 89.0% post‐test; SPTs: 68.5%, 84.3%), as well as the percentage of “Prepared/Somewhat Prepared” responses for all conditions in the aggregate (PTs: 67.5%, 96.5%; SPTs: 37.1%, 90.6%) were significantly different from pre‐test to post‐test (P = .000). There was also a significant difference (P < .05) in the mean overall preparedness Likert scale scores from pre‐test to post‐test for each medical condition for the SPT's, and 15 of the 16 medical conditions (muscle strains: P = .119) for the PTs.

  1. Mechanical ventilation and intra-abdominal hypertension: 'Beyond Good and Evil'

    PubMed Central

    2012-01-01

    Intra-abdominal hypertension is frequent in surgical and medical critically ill patients. Intra-abdominal hypertension has a serious impact on the function of respiratory as well as peripheral organs. In the presence of alveolar capillary damage, which occurs in acute respiratory distress syndrome (ARDS), intra-abdominal hypertension promotes lung injury as well as edema, impedes the pulmonary lymphatic drainage, and increases intra-thoracic pressures, leading to atelectasis, airway closure, and deterioration of respiratory mechanics and gas exchange. The optimal setting of mechanical ventilation and its impact on respiratory function and hemodynamics in ARDS associated with intra-abdominal hypertension are far from being assessed. We suggest that the optimal ventilator management of patients with ARDS and intra-abdominal hypertension would include the following: (a) intra-abdominal, esophageal pressure, and hemodynamic monitoring; (b) ventilation setting with protective tidal volume, recruitment maneuver, and level of positive end-expiratory pressure set according to the 'best' compliance of the respiratory system or the lung; (c) deep sedation with or without neuromuscular paralysis in severe ARDS; and (d) open abdomen in selected patients with severe abdominal compartment syndrome.

    The aim of this study was to determine possible relationships between farm climate conditions, recorded from day 0 to day 40 post-artificial insemination (AI), and late embryo/early fetal loss in high producing dairy cows. Pregnancy was diagnosed by rectal ultrasonography between 28 and 34 days post-AI. Fetal loss was registered when a further 80- to 86-day diagnosis proved negative. Climate variables such as air temperature and relative humidity (RH) were monitored in the cubicles area for each 30-min period. Temperature-humidity indices (THI); cumulative stressful values and episodes of acute change (defined as the mean daily value 1.2 times higher or lower than the mean daily values of the 10 previous days) of the climate variables were calculated. The data were derived from 759 cows in one herd. A total of 692 pregnancies (91.2%) carried singletons and 67 (8.8%) carried twins. No triplets were recorded. Pregnancy loss was recorded in 6.7% (51/759) of pregnancies: 5.6% (39/692) in single and 17.9% (12/67) in twin pregnancies. Using logistic regression procedures, a one-unit increase in the daily cumulative number of hours for the THI values higher than 85 during days 11-20 of gestation caused a 1.57-fold increase in the pregnancy loss, whereas the likelihood of fetal loss increased by a factor of 1.16 for each additional episode of acute variation for the maximum THI values during gestation days 0-40. THI values higher than 85 and episodes of acute variation for the maximum THI values were only recorded during the warm and cool periods, respectively. The presence of twins led to a 3.98-fold increase in pregnancy loss. In conclusion, our findings show that cumulative stressful and episodes of acute variation of climatic conditions can compromise the success of gestation during both the cool and warm periods of the year. Twin pregnancy was confirmed as a main factor associated with pregnancy loss.

    Abdominal bracing is often adopted in fitness and sports conditioning programs. However, there is little information on how muscular activities during the task differ among the muscle groups located in the trunk and from those during other trunk exercises. The present study aimed to quantify muscular activity levels during abdominal bracing with respect to muscle- and exercise-related differences. Ten healthy young adult men performed five static (abdominal bracing, abdominal hollowing, prone, side, and supine plank) and five dynamic (V- sits, curl-ups, sit-ups, and back extensions on the floor and on a bench) exercises. Surface electromyogram (EMG) activities of the rectus abdominis (RA), external oblique (EO), internal oblique (IO), and erector spinae (ES) muscles were recorded in each of the exercises. The EMG data were normalized to those obtained during maximal voluntary contraction of each muscle (% EMGmax). The % EMGmax value during abdominal bracing was significantly higher in IO (60%) than in the other muscles (RA: 18%, EO: 27%, ES: 19%). The % EMGmax values for RA, EO, and ES were significantly lower in the abdominal bracing than in some of the other exercises such as V-sits and sit-ups for RA and EO and back extensions for ES muscle. However, the % EMGmax value for IO during the abdominal bracing was significantly higher than those in most of the other exercises including dynamic ones such as curl-ups and sit-ups. These results suggest that abdominal bracing is one of the most effective techniques for inducing a higher activation in deep abdominal muscles, such as IO muscle, even compared to dynamic exercises involving trunk flexion/extension movements. Key Points Trunk muscle activities during abdominal bracing was examined with regard to muscle- and exercise-related differences. Abdominal bracing preferentially activates internal oblique muscles even compared to dynamic exercises involving trunk flexion/extension movements. Abdominal bracing should be

    Abdominal actinomycosis is a rare infectious disease, caused by gram positive anaerobic bacteria, that may appear as an abdominal mass and/or abscess (Wagenlehner et al. 2003). This paper presents an unusual case of a hemodynamically stable 80-year-old man who presented to the emergency department with 4 weeks of worsening abdominal pain and swelling. He also complains of a 20-bound weight loss in 2 months. A large tender palpable mass in the right upper quadrant was noted on physical exam. Laboratory studies showed a normal white blood cell count, slightly decreased hemoglobin and hematocrit, and mildly elevated total bilirubin and alkaline phosphatase. A CT with contrast was done and showed a liver mass. Radiology and general surgery suspected malignancy and recommended CT guided biopsy. The sample revealed abundant neutrophils and gram positive rods. Cytology was negative for malignancy and cultures eventually grew actinomyces. High dose IV penicillin therapy was given for 4 weeks and with appropriate response transitioned to oral antibiotic for 9 months with complete resolution of symptoms. PMID:28299215

    Abdominal exercises are often performed on roller or rocker mechanisms, which have been aggressively promoted through the television and print media. However, justifications are lacking as to why these devices are superior to traditional abdominal exercises such as crunches. This study sought to describe and compare the range of motion (ROM) of several joints during crunches performed on 4 different abdominal conditioning devices (2 roller and 2 pivot types) and a traditional crunch exercise. Ten men (29 +/- 5.87 years, 177.5 +/- 6.46 cm, 80.96 +/- 11.72 kg) and 10 women (33.4 +/- 10.16 years, 162.23 +/- 3.83 cm, 56.99 +/- 7.36 kg) subjects agreed to participate in the study. Subjects were videotaped in the sagittal plane (60 Hz) using standard kinematic methods. Reflective markers were placed on the right temple, auditory meatus, shoulder, hip, knee, ankle, heel, toe, and 2 sternum markers placed on a foam piece strapped to the subject's chest. The videotaped movements were automatically digitized (PEAK5 2-D) and the data smoothed using a Butterworth filter. Relative angular ROMs of the head (temple, auditory meatus, shoulder); neck (auditory meatus, shoulder, hip); trunk (near sternum, shoulder, hip); hip (shoulder, hip, knee); sternum/head (sternum near and sternum far with temple and auditory meatus); sternum/trunk (sternum near and sternum far with shoulder and hip); and a sum of 4 angles (head, neck, trunk, hip) were calculated. Sex by equipment repeated measures analyses of variance (ANOVAs) were calculated on the angles of the 5 exercises. When no main effect for sex was found, the data were collapsed across sex and a one-way ANOVA with repeated measures was calculated on the resulting data. Post hoc analyses of pairwise differences were calculated using Tukey's honestly significant difference statistic. Results showed that crunches performed with the abdominal devices resulted in less ROM in all angles measured when compared with a traditional crunch. The

    This study aims to review the imaging findings of distal (thoracic and abdominal) complications related to ventriculo-peritoneal (VP), ventriculo-pleural (VPL), and ventriculo-atrial (VA) cerebrospinal fluid (CSF) shunt catheter placement. Institution review board-approved single-center study of patients with thoracic and abdominal CSF catheter-related complications on cross-sectional imaging examinations over a 14-year period was performed. Clinical presentation, patient demographics, prior medical history, and subsequent surgical treatment were recorded. The presence or absence of CSF catheter-related infection and/or acute hydrocephalus on cross-sectional imaging was also recorded. There were 81 distal CSF catheter-related complications identified on 47 thoracic or abdominal imaging examinations in 30 patients (age 5-80 years, mean 39.3 years), most often on CT (CT = 42, MRI = 1, US = 4). Complications included 38 intraperitoneal and 11 extraperitoneal fluid collections. Extraperitoneal collections included nine abdominal wall subcutaneous (SC) pseudocysts associated with shunt migration and obesity, an intrapleural pseudocyst, and a breast pseudocyst. There were also two large VPL-related pleural effusions, a fractured catheter in the SC tissues, and a large VA shunt thrombus within the right atrium. Ten patients (33.3 %) had culture-positive infection from CSF or shunt catheter samples. Ten patients (33.3 %) had features of temporally related acute or worsening hydrocephalus on neuroimaging. In four of these patients, the detection of thoracic and abdominal complications on CT preceded and predicted the findings of acute hydrocephalus on cranial imaging. Thoracic and abdominal complications of CSF shunts, as can be identified on CT, include shunt infection and/or obstruction, may be both multiple and recurrent, and may be predictive of concurrent acute intracranial problems.

    Acute organophosphate poisoning (OP) shows several severe clinical symptoms due to its strong blocking effect on cholinesterase. Acute pancreatitis is one of the complications associated with acute OP, but this association still may not be widely recognized. We report here the case of a 73-year-old man who had repeated abdominal pain during and after the treatment of acute OP. Hyperamylasemia and a 7-cm pseudocyst in the pancreatic tail were noted on investigations. We diagnosed pancreatic pseudocyst that likely was secondary to an episode of acute pancreatitis following acute OP. He was initially treated with a long-term intravenous hyperalimentation, protease inhibitors and octerotide, but eventually required surgical intervention, a cystgastrostomy. Acute pancreatitis and hyperamylasemia are known to be possible complications of acute OP. It is necessary to examine and assess pancreatic damage in patients with acute OP.

    Various biliary pathologic conditions can lead to acute abdominal pain. Specific diagnosis is not always possible clinically because many biliary diseases have overlapping signs and symptoms. Imaging can help narrow the differential diagnosis and lead to a specific diagnosis. Although ultrasonography (US) is the most useful imaging modality for initial evaluation of the biliary system, multidetector computed tomography (CT) is helpful when US findings are equivocal or when biliary disease is suspected. Diagnostic accuracy can be increased by optimizing the CT protocol and using multiplanar reformations to localize biliary obstruction. CT can be used to diagnose and stage acute cholecystitis, including complications such as emphysematous, gangrenous, and hemorrhagic cholecystitis; gallbladder perforation; gallstone pancreatitis; gallstone ileus; and Mirizzi syndrome. CT also can be used to evaluate acute biliary diseases such as biliary stone disease, benign and malignant biliary obstruction, acute cholangitis, pyogenic hepatic abscess, hemobilia, and biliary necrosis and iatrogenic complications such as biliary leaks and malfunctioning biliary drains and stents. Treatment includes radiologic, endoscopic, or surgical intervention. Familiarity with CT imaging appearances of emergent biliary pathologic conditions is important for prompt diagnosis and appropriate clinical referral and treatment.

    The acute toxicity of physically and chemically dispersed crude oil and the dispersant Corexit 9500 were evaluated for key Arctic species. The copepod Calanus glacialis, juvenile Arctic cod (Boreogadus saida), and larval sculpin (Myoxocephalus sp.) were tested under conditions representative of the Beaufort and Chukchi Seas during the ice-free season. The toxicity of 3 water-accommodated fractions (WAF) of Alaska North Slope crude oil was examined with spiked, declining exposures. A dispersant-only test was conducted with the copepod C. glacialis. Each preparation with oil (WAF, breaking wave WAF [BWWAF], and chemically enhanced WAF [CEWAF]) produced distinct suites of hydrocarbon constituents; the total concentrations of oil were lowest in WAF and highest in CEWAF preparations. The relative sensitivity for the different species and age classes was similar within each WAF type. Median lethal concentration values based on total petroleum hydrocarbons ranged from 1.6 mg/L to 4.0 mg/L for WAF and BWWAF treatments and from 22 mg/L to 62 mg/L for CEWAF. For Corexit 9500 exposures, median lethal concentration values ranged from 17 mg/L to 50 mg/L. The differences in the relative toxicity among the accommodated fractions indicated that the majority of petroleum hydrocarbons in the CEWAF are in less acutely toxic forms than the components that dominate the WAF or BWWAF. Further evaluation showed that the parent polycyclic aromatic hydrocarbon compounds, specifically naphthalene, were highly correlated to acute toxicity. Environ Toxicol Chem 2013;32:2284–2300.

    INTRODUCTION The prevalence of hiatal hernias and para-oesophageal hernias (PEHs) is lower in Asian populations than in Western populations. Progressive herniation can result in giant PEHs, which are associated with significant morbidity. This article presents the experience of an Asian acute care tertiary hospital in the management of giant PEH and parahiatal hernia. METHODS Surgical records dated between January 2003 and January 2013 from the Department of Surgery, Changi General Hospital, Singapore, were retrospectively reviewed. RESULTS Ten patients underwent surgical repair for giant PEH or parahiatal hernia during the study period. Open surgery was performed for four patients with giant PEH who presented emergently, while elective laparoscopic repair was performed for six patients with either giant PEH or parahiatal hernia (which were preoperatively diagnosed as PEH). Anterior 180° partial fundoplication was performed in eight patients, and mesh reinforcement was used in six patients. The electively repaired patients had minimal or no symptoms during presentation. Gastric volvulus was observed in five patients. There were no cases of mortality. The median follow-up duration was 16.3 months. There were no cases of mesh erosion, complaints of dysphagia or recurrence of PEH in all patients. CONCLUSION Giant PEH and parahiatal hernia are underdiagnosed in Asia. Most patients with giant PEH or parahiatal hernia are asymptomatic; they often present emergently or are incidentally diagnosed. Although surgical outcomes are favourable even with a delayed diagnosis, there should be greater emphasis on early diagnosis and elective repair of these hernias. PMID:26778633

    Appendicular sarcoidosis is a very rare cause of acute abdominal pain, with only seven cases reported previously in the literature. A 45-year-old woman, known to have sarcoidosis, presented to the emergency department with a 1-week history of epigastric and right iliac fossa abdominal pain. At diagnostic laparoscopy, an acutely inflamed appendix was found and removed as well as an omental mass which was biopsied. Subsequent histopathological examination of the appendix demonstrated appendicular sarcoidosis without acute appendicitis and chronic inflammatory changes in the omental biopsy. The patients’ symptoms completely resolved postoperatively. It is important to undertake urgent operative intervention in patients with sarcoidosis who present with right iliac fossa pain, owing to the high risk of perforation. PMID:23162022

    Rectus sheath haematoma is a rare cause of abdominal pain. It can be easily confused for other causes of acute abdomen and may even lead to unnecessary laparotomies. Our patient has the rectus sheath haematoma because of violent coughing and on presentation had no obvious clinical sign pointing to the same. Diagnosis was made by a CT scan of the abdomen, and patient was treated conservatively. Rectus sheath haematomas are usually present on the posterior aspect of the rectus muscles and thus may not be clinically appreciable.

    An otherwise healthy 36-year-old man presented with sudden-onset right upper quadrant abdominal pain and vomiting. A bedside ultrasound, performed to evaluate hepatobiliary pathology, revealed a normal gallbladder but free intraperitoneal fluid. After an expedited CT and emergent explorative laparotomy, the patient was diagnosed with a small bowel obstruction with ischemia secondary to midgut volvulus. Though midgut volvulus is rare in adults, delays in definitive diagnosis and management can result in bowel necrosis. Importantly, an emergency physician must be able to recognize bedside ultrasound findings associated with acutely dangerous intrabdominal pathology. PMID:27625732

    The porphyrias comprise a set of diseases, each representing an individual defect in one of the eight enzymes mediating the pathway of heme synthesis. The diseases are genetically distinct but have in common the overproduction of heme precursors. In the case of the acute (neurologic) porphyrias, the cause of symptoms appears to be overproduction of a neurotoxic precursor. For the cutaneous porphyrias, it is photosensitizing porphyrins. Some types have both acute and cutaneous manifestations. The clinical presentation of acute porphyria consists of abdominal pain, nausea, and occasionally seizures. Only a small minority of those who carry a mutation for acute porphyria have pain attacks. The triggers for an acute attack encompass certain medications and severely decreased caloric intake. The propensity of females to acute attacks has been linked to internal changes in ovarian physiology. Symptoms are accompanied by large increases in delta-aminolevulinic acid and porphobilinogen in plasma and urine. Treatment of an acute attack centers initially on pain relief and elimination of inducing factors such as medications; glucose is administered to reverse the fasting state. The only specific treatment is administration of intravenous hemin. An important goal of treatment is preventing progression of the symptoms to a neurological crisis. Patients who progress despite hemin administration have undergone liver transplantation with complete resolution of symptoms. A current issue is the unavailability of a rapid test for urine porphobilinogen in the urgent-care setting. PMID:26357631

    Accurate, rapid, and noninvasive health assessments are required to establish more appropriate endpoints in mouse cancer models where tumor size is not easily measured. We evaluated potential endpoints in mice with experimentally induced peritoneal lymphoma, an abdominal tumor model, by comparing body weight, body condition, and behavior with those of a control group of mice not developing lymphoma. Our hypothesis was that body weight would increase or plateau, whereas body condition and behavioral scores would decrease, as disease progressed. Results indicated that body weight did not differ significantly between the control and experimental groups, but the experimental group experienced significant decreases in both body condition and behavioral scores. Our results support the use of body condition and behavioral scoring as adjunctive assessment methods for mice involved in abdominal lymphoma tumor studies in which health may decline despite an increase or plateau in body weight.

    Postpartum Ovarian Vein Thrombosis (POVT) is a rare, but serious condition that causes slow quadrant pain in the postpartum period. POVT must be considered in the differential diagnosis of postpartum acute abdomen. We hereby report a case on a 36-year-old Italian woman who developed an acute abdomen a week after spontaneous vaginal delivery. She had persistent fever and constipation. Diagnosis of POVT was made with an abdominal Computed Tomography (CT) and treatment with heparin and broad-spectrum antibiotics were started. After 72 hours, the patient was switched from low molecular weight heparin to oral anticoagulant treatment. After 5 months a complete recanalization was demonstrated by abdomen CT and the treatment was stopped 6 months after diagnosis. POVT is a diagnosis of exclusion in the puerperium. This case illustrated that POVT may also occur in low risk patient. PMID:27042537

    A young female presented with acute abdominal pain of two days duration consistent with acute pancreatitis. During her stay in the hospital she had a sudden drop in hemoglobin to 6 g/dl without any overt blood loss. On evaluation, it was evident that she had acute pancreatitis, in addition to displaying features of autoimmune hemolytic anemia. She had been a known case of systemic lupus erythematosus (SLE) and had discontinued her treatment. She was managed with methylprednisolone pulse therapy. Her clinical condition improved, and she has been regularly attending our clinic for the last 2 years. According to a literature search in Medline, it would appear that this is the first report of a case in which SLE with autoimmune hemolytic anemia has been associated with acute pancreatitis in a single case.

    Conditioning regimens used during stem cell transplant provide prolonged control or cure of the disease in patients with acute lymphoblastic leukemia (ALL). In this study, we present a comparison of treatment results for 95 patients with ALL who underwent allogeneic hematopoietic stem cell transplant (AHSCT) with total body irradiation plus cyclophosphamide (TBI + Cy) or busulfan plus cyclophosphamide (Bu + Cy) as conditioning regimen. Median age was 25 (range: 9-54) years. Median follow-up was 24 (range: 3-107) months. Median overall survival (OS) was found to be 29 months. Median event-free survival (EFS) was 9 months. Median OS was 37 months in the TBI + Cy arm, while it was 12 months in the Bu + Cy arm, suggesting a significant advantage favoring the TBI + Cy arm (p = 0.003). Median EFS was 13 months in the TBI + Cy arm, while it was 4 months in the Bu + Cy arm, indicating a significant difference (p = 0.006). In univariate and multivariate analysis, it was found that high OS and EFS were significantly correlated with TBI + Cy conditioning regimen and lack of transplant-related mortality (p < 0.05). The TBI + Cy conditioning regimen was found to be superior to the Bu + Cy regimen in patients with ALL undergoing AHSCT regarding both OS and EFS.

    In the myeloablative transplant setting, the early use of fluconazole prophylaxis provides a benefit in overall survival. Recent changes in transplantation practices, including the use of peripheral blood stem cells (PBSC) and/or reduced intensity conditioning (RIC) regimen may have favorably impacted the epidemiology of invasive fungal infections (IFI) after allogeneic stem cell transplantation (allo-SCT). Yet, the impact of removing fluconazole prophylaxis after RIC PBSC allotransplant is ill known. Here, a retrospective analysis was performed comparing patients who received fluconazole as antifungal prophylaxis (n = 53) or not (n = 56) after allo-SCT for acute leukemia or myelodysplastic/myeloproliferative syndrome. Sixteen IFI were documented (14 %) at a median time of 103 days after transplantation, including eight before day +100, at a similar rate, whether the patients received fluconazole prophylaxis (13 %) or not (16 %). IFI were due mainly to Aspergillus species (87 %), and only two Candida-related IFI (13 %) were documented in the non-fluconazole group before day +100. The incidences of IFI (overall, before or after day +100) as well as 3-year overall and disease-free survival, non-relapse mortality, or acute and chronic graft-versus-host disease (GVHD) were similar between both groups. In conclusion, this study suggests that fluconazole may not be required at the initial phase of RIC allo-SCT using PBSC. This result has to be confirmed prospectively while Aspergillus prophylaxis should be discussed in this particular setting.

    We report the results of a prospective study of a reduced-intensity conditioning (RIC) regimen followed by allogeneic peripheral blood stem cell transplantation (PBSCT) from an HLA-identical sibling in 37 patients with acute myeloid leukemia (AML; n = 17) or myelodysplastic syndrome (MDS; n = 20). The median age was 57 years, and 22 (59%) were beyond the early phase of their disease. The incidence of grade II to IV acute graft-versus-host disease (GVHD) was 19% (5% grade III-IV), and the 1-year incidence of chronic extensive GVHD was 46%. With a median follow-up of 297 days (355 days in 24 survivors), the 1-year probability of transplant-related mortality was 5%, and the 1-year progression-free survival was 66%. The 1-year incidence of disease progression in patients with and without GVHD was 13% (95% CI, 4%-34%) and 58% (95% CI, 36%-96%), respectively (P =.008). These results suggest that a graft-versus-leukemia effect plays a crucial role in reducing the risk of relapse after a RIC allograft in AML and MDS.

    Foot-and-mouth disease (FMD) is a highly contagious and economically important viral disease of cloven-hoofed animals, including domestic and wild host species. During recent FMD outbreaks in India, spontaneous abortions were reported amongst FMD-affected and asymptomatic cows. The current study was an opportunistic investigation of these naturally occurring bovine abortions to assess causality of abortion and vertical transmission of FMDV from infected cows to fetuses. For this purpose, fetal tissue samples of eight abortuses (heart, liver, kidney, spleen, palatine tonsil, umbilical cord, soft palate, tongue, lungs, and submandibular lymph node) were collected and screened by various detection methods, including viral genome detection, virus isolation, and immunomicroscopy. Amongst these cases, gross pathological changes were observed in 3 abortuses. Gross pathological findings included blood-tinged peritoneal and pleural effusions and myocarditis. Hearts of infected calves had mild to moderate degeneration and necrosis of the myocardium with moderate infiltration by mixed inflammatory cells. Localization of FMDV antigen was demonstrated in lungs and soft palate by immunomicroscopy. FMDV serotype O viral genome was recovered from 7 of 8 cases. Infectious FMDV serotype O was rescued by chemical transfection of the total RNA extracted from three soft palate samples and was sequenced to confirm 100% identity of the VP1 (capsid) coding region with isolates collected from infected cattle during the acute phase of infection. Based upon these findings, it may be concluded that FMDV-associated abortion occurred among the infected pregnant cows included within this study and FMDV was subsequently transmitted vertically to fetuses. This is the first documentation of FMDV-associated abortions in cattle. PMID:27977708

    It was analyzed the features of different forms of acute pancreatitis in 1001 patients including 324 cases with pancreatonecrosis and 245 patients with middle severity of disease. It was shown that monitoring of patients' condition and destructive process in pancreas by using of modified SOFA-scale and evaluation of sonographic signs of inflammation are advisable. Flow indicators including resistance index and the maximum flow velocity in celiac trunk and superior mesenteric artery represented severity of gland's destruction. Sonographic investigation revealed small-focal pancreonecrosis. It allows to differentiate medical tactics. Surgical treatment was performed in 582 patients. Efficiency of surgical treatment is determined by diagnostic methods, timely sanation of destructive focuses of pancreas, abdominal cavity, retroperitoneal fiber, adequate drainage and mini-invasive techniques using in case of purulent complications. The main prognostic factors of development of complications and adverse outcomes are determined.

    Acute vascular abdomen is a severe and life-threatening pathology due to arterial degeneration, leading to hemorrhage or arterial occlusion leading to ischemia. Differential diagnosis of patients with severe abdominal pain and/or shock include several vascular and traumatic diseases, the most common being rupture of abdominal aortic aneurysm (AAA), or less frequently rupture of visceral artery aneurysm. Also acute aortic dissection, iatrogenic injury and acute mesenteric ischemia may lead to acute vascular abdomen. Clinical evaluation of the haemodynamic status of the patient may be very difficult, and may require airway maintenance and ventilation with a rapid treatment of hemorrhagic shock. In the stable patient with an uncertain diagnosis, CT scan, NMR and selective angiography may be helpful in diagnosis before vascular repair. On the contrary, the unstable patient, after hemodynamic resuscitation, must be operated on expeditiously. We present our vascular algorithms, to assess timing of diagnosis and treatment of this severe acute disease.

    Small bowel ischemia is a disorder related to a variety of conditions resulting in interruption or reduction of the blood supply of the small intestine. It may present with various clinical and radiologic manifestations, and ranges pathologically from localized transient ischemia to catastrophic necrosis of the intestinal tract. The primary causes of insufficient blood flow to the small intestine are various and include thromboembolism (50% of cases), nonocclusive causes, bowel obstruction, neoplasms, vasculitis, abdominal inflammatory conditions, trauma, chemotherapy, radiation, and corrosive injury. Computed tomography (CT) can demonstrate changes because of ischemic bowel accurately, may be helpful in determining the primary cause of ischemia, and can demonstrate important coexistent findings or complications. However, common CT findings in acute small bowel ischemia are not specific and, therefore, it is often a combination of clinical, laboratory and radiologic signs that may lead to a correct diagnosis. Understanding the pathogenesis of various conditions leading to mesenteric ischemia and being familiar with the spectrum of diagnostic CT signs may help the radiologist recognize ischemic small bowel disease and avoid delayed diagnosis. The aim of this article is to provide a review of the pathogenesis and various causes of acute small bowel ischemia and to demonstrate the contribution of CT in the diagnosis of this complex disease.

    Cytokines are known to play pivotal roles in cancer initiation, progression and pathogenesis. Accumulating evidences suggest differences in basal and stress-induced cytokine profiles of cancers with diverse origin. However, a comprehensive investigation characterising the cytokine profile of various tumor types after acute and fractionated doses of gamma-irradiation, and its effect on survival of bystander cells is not well known in literature. In the present study, we have evaluated the cytokine secretion profile of human tumor cell lines (HT1080, U373MG, HT29, A549 and MCF-7) either before (basal) or after acute (2, 6 Gy) and fractionated doses (3×2 Gy) of gamma-irradiation in culture medium obtained from these cells by multiplex bead array/ELISA. Moreover, clonogenic assays were performed to evaluate the effect of conditioned medium (CM) on the survival and growth of respective cells. Based on the screening of 28 analytes, our results showed that the basal profiles of these cell lines varied considerably in terms of the number and magnitude of secreted factors, which was minimum in MCF-7. Interestingly, TNF-α, IL-1β, PDGF-AA, TGF-β1, fractalkine, IL-8, VEGF and GCSF were found in CM of all the cell lines. However, secretion of certain cytokines was cell line-specific. Moreover, CM caused increase in clonogenic survival of respective tumor cells (in the order HT1080>U373MG>HT29>A549>MCF-7), which was correlated with the levels of IL-1β, IL-6, IL-8, GMCSF and VEGF in their CM. After irradiation, the levels of most of the cytokines increased markedly in a dose dependent manner. The fold change in cytokine levels was lower in irradiated conditioned medium (ICM) of tumor cells collected after fractionated than respective acute dose, except in MCF-7. Interestingly, amongst these cell lines, the radiation-induced fold increase in cytokine levels was maximum in ICM of A549 cells. Moreover, bystander A549 cells treated with respective ICM showed dose dependent

    Acute lead poisoning is not a common pathology seen in the pediatrician's office. Lead poisoning symptoms can be digestive or neurological, and they can be confused with other pathologies. That is the reason why it should be considered and, in case of doubt, complementary studies to confirm lead poisoning should be requested. This is the case of a nine-year-old child that comes to the office with a strong abdominal pain and vomiting, and after a close physical examination and a detailed anamnesis, a suspicious diagnosis of "acute" lead poisoning is obtained. Therefore, the infant is hospitalized, and after taking a venous sampling to confirm the lead level, a chelation therapy is performed under the toxicology expert's supervision.

    2014-08-01

    Acute primary haemorrhagic omental torsion is an atypical and deceptive cause of acute abdomen that could closely mimic a myriad of intra-abdominal catastrophes, especially perforated appendicitis. The author reports a 30 years man who had presented with gradually worsening right-sided abdominal pain of 2 days duration. Laboratory work-up and abdominal radiographs were inconclusive. Abdominal sonography detected presence of free fluid in the pelvic cul-de-sac. Based on clinical and sonographic findings, presumptive diagnosis of perforated appendicitis was made and the patient was explored through extended Rockey-Davis incision. About 500 - 700 ml of dark-coloured blood (haemoperitoneum) was present in the peritoneal cavity and the pelvis secondary to acute haemorrhagic omental torsion. The appendix was grossly normal. Omentectomy and prophylactic appendicectomy resulted in uneventful recovery of the patient. Acute primary omental torsion is an uncommon pathology that must be kept in mind during differential diagnosis of acute abdomen, especially acute or perforated appendicitis.

    Abdominal wall emphysema is a common complication of laparoscopic surgery. This condition is usually harmless; however, if an infection occurs, it can develop into a serious condition such as necrotizing fasciitis. We report a case of a 51-year-old woman suffering from severe cellulitis that spread from an area of abdominal wall emphysema after laparoscopic surgery for sigmoid colon cancer. Recognizing this complication, early diagnosis, and prompt treatment are cornerstones for successful management of this potentially fatal disease.

    Small bowel perforation is an emergent medical condition for which the diagnosis is usually not made clinically but by CT, a common imaging modality used for the diagnosis of acute abdomen. Direct CT features that suggest perforation include extraluminal air and oral contrast, which are often associated with secondary CT signs of bowel pathology. This pictorial review illustrates the CT findings of small bowel perforation caused by various clinical entities.

    Varicella-zoster virus (VZV) is a type of herpes virus known to cause varicella, mainly in young children, and herpes zoster in adults. Although generally non-lethal, VZV infection can be associated with serious complications, particularly in adults. Acute pancreatitis caused by VZV infection is a rare event, with reports primarily concerning immunocompromised individuals. Here we report a 44-year-old immunocompetent female who developed acute pancreatitis associated with VZV infection. The patient presented with vomiting and persistent pain in the upper quadrant less than one week after diagnosis and treatment for a herpes zoster-related rash with stabbing pain on the abdomen and dorsal right trunk side. A diagnosis of acute pancreatitis was confirmed based on abdominal pain, elevated levels of urine and serum amylase, and findings of peri-pancreatic exudation and effusions by computed tomography and magnetic resonance cholangiopancreatography. This case highlights that, though rare, acute pancreatitis should be considered in VZV patients who complain of abdominal pain, especially in the epigastric area. Early detection and proper treatment are needed to prevent the condition from deteriorating further and to minimize mortality.

    This study determined the effectiveness of antioxidant supplementation on high-intensity exercise-heat stress. Six males completed a high-intensity running protocol twice in temperate conditions (TEMP; 20.4°C), and twice in hot conditions (HOT; 34.7°C). Trials were completed following7 days supplementation with 70 ml·day(-1) effective microorganism-X (EM-X; TEMPEMX or HOTEMX) or placebo (TEMPPLA or HOTPLA). Plasma extracellular Hsp72 (eHsp72) and superoxide dismutase (SOD) were measured by ELISA. eHsp72 and SOD increased pre-post exercise (p < 0.001), with greater eHsp72 (p < 0.001) increases observed in HOT (+1.5 ng·ml(-1)) compared to TEMP (+0.8 ng·ml(-1)). EM-X did not influence eHsp72 (p > 0.05). Greater (p < 0.001) SOD increases were observed in HOT (+0.22 U·ml(-1)) versus TEMP (+0.10 U·ml(-1)) with SOD reduced in HOTEMX versus HOTPLA (p = 0.001). Physiological and perceptual responses were all greater (p < 0.001) in HOT versus TEMP conditions, with no difference followed EM-X (p > 0.05). EM-X supplementation attenuated the SOD increases following HOT, potentiating its application as an ergogenic aid to ameliorate oxidative stress.

    The authors analyse 115 cases of acute fatty liver of pregnancy, proven histologically. Characteristics of the condition is the finding of central nuclei in the hepatocytes containing microvesicular droplets. The disease occurs more frequently in primiparous women (54 per cent) and usually occurs in the third trimester of the pregnancy. A pre-icteric phase usually precedes the jaundice and during that time there is usually vomiting and/or nausa with abdominal pain or anarexia. In 92 per cent of case there is transient loss of consciousness with hepatic encephalopathy. Further tests show that there is more defective liver function than would be expected from the extent of cell lysis; and there is defective renal function. The worst complications are intestinal haemorrhages (48 per cent of cases)--genital bleeding (43 per cent of cases)--shock--diffuse intravascular coagulation and complications associated with coma. Maternal mortality at present runs at 25 per cent and fetal mortality at 60 per cent. The condition does not recur. Early evacuation of the uterus is recommended by most authors and does probably improve the outlook. The various hypotheses concerning the aetiology are discussed.

    Continent urinary diversion has gained increasing popularity in the pediatric population during the last few decades. In adults, continent diversions are usually needed to replace a bladder after cystectomy for invasive carcinoma. Subsequently, the creation of functional and cosmetically hidden urinary and cecal abdominal stomas has become an integral part of many urinary reconstructive procedures. These techniques, originally developed for pediatric urinary reconstruction have gained increasing popularity for adult patients in need of a continence procedure. In the current manuscript, we review the technical aspects of site selection, mucocutaneous anastomosis, cosmetic appearance, and management of associated complications.

    This case presented challenging diagnostic and management issues in a young healthy man who presented with abdominal pain and new-onset hypertension. The differential diagnosis evolved over the course of the clinical presentation. The patient had severe vascular involvement of his renal and basal cerebral arteries that initially was assumed to be due to a vasculitic process or hypercoagulable state. Finally it became apparent that the patient did not have a systemic illness but rather a localized vascular disease most likely due to segmental arterial mediolysis, a rare, under-recognized condition that can potentially be fatal. This condition is often difficult to distinguish from fibromuscular dysplasia. It is important to recognize and correctly diagnose the condition, particularly in the acute phase of the disease, because delay in diagnosis can contribute to morbidity and mortality. PMID:25583291

    Acute bacterial parotitis (ABP) is a relatively uncommon condition that tends to occur in debilitated older patients. We report a case of an older woman that presented with an acute intracerebral hemorrhage who developed ABP. This morbidity led to endotracheal intubation, mechanical ventilation, tracheostomy and gastrostomy, all of which were not initially needed. We discuss the proposed physiopathology and etiopathogenesis of ABP in adults.

    INTRODUCTION Internal abdominal hernias are infrequent but an increasing cause of bowel obstruction still often underdiagnosed. Among adults its usual causes are congenital anomalies of intestinal rotation, postsurgical iatrogenic, trauma or infection diseases. PRESENTATION OF CASE We report the case of a 63-year-old woman with history of chronic constipation. The patient was hospitalized for two days with acute abdominal pain, abdominal distension and inability to eliminate flatus. The X-ray and abdominal computerized tomography scan (CT scan) showed signs of intestinal obstruction. Exploratory laparotomy performed revealed a trans-mesenteric hernia containing part of the transverse colon. The intestine was viable and resection was not necessary. Only the hernia was repaired. DISCUSSION Internal trans-mesenteric hernia constitutes a rare type of internal abdominal hernia, corresponding from 0.2 to 0.9% of bowel obstructions. This type carries a high risk of strangulation and even small hernias can be fatal. This complication is specially related to trans-mesenteric hernias as it tends to volvulize. Unfortunately, the clinical diagnosis is rather difficult. CONCLUSION Trans-mesenteric internal abdominal hernia may be asymptomatic for many years because of its nonspecific symptoms. The role of imaging test is relevant but still does not avoid the necessity of exploratory surgery when clinical features are uncertain. PMID:24880799

  6. Enhancement of acute ethanol hepatotoxicity under conditions of low oxygen supply and ischemia/reperfusion. The role of oxygen radicals.

    Younes, M; Wagner, H; Strubelt, O

    1989-10-15

    Using isolated hemoglobin-free perfused rat livers we studied the effect of low oxygen supply on ethanol hepatotoxicity in two models. In the first model resembling low blood supply, perfusion rate was lowered from 60 to 10 ml/min after a 30 min-equilibration phase and kept low for 60 min. As a consequence, oxygen consumption fell from 1.76 +/- 0.15 mumol/min/g to 0.51 +/- 0.02 mumol/min/g. In the second model, total ischemia was accomplished by interruption of the perfusion for 30 min and was followed by reperfusion at a perfusion rate of 60 ml/min for a further 30 min. In this model, oxygen consumption returned immediately to normal values upon reperfusion. In both models, low oxygen supply had no toxic effects of its own on livers from fed rats. While ethanol (3 g/l) given under normoxic conditions led to a moderate hepatotoxicity, its application in both models of partial as well as total ischemia and reperfusion resulted in a marked liver damage as evidenced by a strong release of sorbitol dehydrogenase, glutamate-pyruvate-transaminase, lactate dehydrogenase and glutathione, as well as by an increase in hepatic calcium content. Inhibition of ethanol metabolism by 4-methylpyrazol prevented liver damage in both models indicating that metabolism of ethanol is a prerequisite for its toxicity to occur. Also, hepatotoxicity was inhibited partially by catalase and superoxide dismutase and nearly totally by deferrioxamine and allopurinol. Thus, reactive oxygen species which are produced during ethanol metabolism as well as under conditions of low oxygen supply are mediators of hepatic damage in both models employed.

    Toxocariasis is an extensive helminthic infection that leads to visceral larva migrans in humans. A 2.5-year-old girl referred for abdominal mass. She had history of pharyngitis for two weeks. There were no other symptoms. Abdominal examination revealed an irregular solid mass in right lower quadrant (RLQ). Abdominal ultrasonography revealed an echohetrogenic large mass in RLQ, liver, and retroperitoneal area. Abdominal CT scan showed a huge mass. At laparotomy a large retroperitoneal mass that involved right liver lobe, bladder, ileocecal valve, small and large intestines was found. At histopathology diagnosis of toxocariasis was made.

    Over the past 9 years, ten patients have presented to the Thoracic Unit, Glasgow Royal Infirmary, with 12 empyemas secondary to intra-abdominal sepsis. In eight patients, the presenting signs and symptoms were wrongly attributed to primary intra-thoracic pathology. All were subsequently found to have intra-abdominal sepsis. The presence of empyema after recent abdominal surgery or abdominal pain strongly suggests a diagnosis of ipsilateral subphrenic abscess. Adequate surgical drainage is essential. In our experience, limited thoracotomy with subdiaphragmatic extension offers the best access to both pleural and subphrenic spaces and provides the greatest chance of eradicating infection on both sides of the diaphragm.

    Possible non-thermal effects of radio frequency electromagnetic fields (RF-EMF) on retinal ganglion cells were studied in vitro under conditions of constant temperature. Isolated mouse retinae were exposed to GSM-900, GSM-1800, and universal mobile telecommunication system (UMTS) RF-EMF applying specific absorption rates (SAR) of 0 (sham), 0.02, 0.2, 2, and 20 W/kg. Temperature was kept constant within ±0.5 to 1 °C for GSM-900 and ±0.5 °C for GSM-1800 and UMTS. Responses of retinal ganglion cells to light stimuli of three intensities (0.5, 16, and 445 lx) were recorded before, during, and up to 35 min after exposure. Experiments were performed under double-blind conditions. Changes in light responses during and after exposure were determined for each condition (RF-EMF; SAR value; light intensity) with respect to the responses before exposure, respectively. Changes were calculated using the Euclidian distance of the n-dimensional response vectors, respectively. Some changes already occurred during sham (0 W/kg) exposure, reflecting the intrinsic variability in retinal ganglion cell responses. Comparison of the distance values from sham exposure with those from actual exposure yielded no significant differences. In addition, linear regression analysis of the distance values versus SAR values yielded no consistent dependence of light response changes. From these results we conclude that RF-EMF exposure at three mobile phone frequencies (GSM-900, GSM-1800, UMTS) and SARs up to 20 W/kg has no acute effects on retinal ganglion cell responses under constant temperature conditions.

    Social stress modifies the activity of brain areas involved in the rewarding effects of psychostimulants, inducing neuroadaptations in the dopaminergic mesolimbic system and modifying the sensitivity of dopamine receptors. In the present study we evaluated the effect of the dopamine D1- and D2-like receptor antagonists (SCH23390 and raclopride, respectively) on the short-time effects of acute social defeat (ASD). Male OF1 mice were socially defeated before each conditioning session of the conditioned place preference (CPP) induced by 1mg/kg or 25mg/kg of cocaine plus the corresponding dopamine antagonist. A final experiment was designed to evaluate the effect of the dopamine antagonists on the CPP induced by 3mg/kg of cocaine with or without a stress experience. Mice exposed to ASD showed an increase in reinstatement of the conditioned reinforcing effects of cocaine that was blocked by all of the dopamine receptor antagonists. Blockade of dopamine D2-like receptors with raclopride specifically prevented the effects of stress without affecting the rewarding properties of cocaine. However, SCH23390 inhibited cocaine-induced preference in the control groups and even induced aversion in defeated mice conditioned with the lower dose of cocaine. Moreover, the lowest dose of SCH23390 blocked the rewarding effects of 3mg/kg of cocaine-induced CPP. Our results confirm that the dopamine D2 receptor is involved in the short-term effects of ASD on the rewarding effects of cocaine. The dopamine D1 receptor is clearly involved in the rewarding effects of cocaine, but its role in the effects of ASD remains to be demonstrated.

    Hemorrhagic cystitis (HC) is a common complication after allogeneic hematopoietic SCT (allo-HSCT). Several risk factors have been suggested including BU-containing myeloablative conditioning, unrelated donors and GVHD, but these have not been consistently reported. We conducted a retrospective study including 339 allo-HSCT recipients between 2009 and 2012. Of 339 patients, 79 (23.3%) developed HC with 2-year cumulative incidence of 24.0% (95% confidence interval, 19.4-28.9). The median onset time was 45 days (range, 16-430) after allo-HSCT. Sixty-two patients (84%) out of 74 evaluated for urine BK virus PCR testing showed a positive result (mean 2.0 × 10(10) copies of DNA per mL). In univariate analysis, myeloablative conditioning, HLA-mismatched donor, CMV viremia and acute GVHD (aGVHD) grade 3-4 were significantly associated with the risk of HC. Multivariate analysis confirmed all associating factors identified in univariate analysis except for HLA-mismatched donor: myeloablative conditioning (hazard ratio (HR) 2.63, P=0.003), CMV viremia (HR 1.88, P=0.014) and aGVHD grade 3-4 (HR 1.71, P=0.029). HC did not affect OS or non-relapse mortality. Symptomatic HC is a frequent complication following allo-HSCT, with a 2-year cumulative incidence of 24.0%. Three clinical factors associated with HC were identified including myeloablative conditioning, CMV viremia and severe aGVHD.

    Reduced-intensity conditioning/nonmyeloablative conditioning regimens are increasingly used in allogeneic hematopoietic cell transplantation (HCT). Reports have shown CD34(+) dose to be important for transplantation outcome using myeloablative conditioning. The role of CD34(+) dose of peripheral blood progenitor cells (PBPC) has not been previously analyzed in a large population undergoing reduced-intensity conditioning/nonmyeloablative HCT. We studied 1054 patients, ages 45 to 75 years, with acute myeloid leukemia or myelodysplastic syndrome who underwent transplantation between 2002 and 2011. Results of multivariate analysis showed that PBPC from HLA-matched siblings containing <4 × 10(6) CD34(+)/kg was associated with higher nonrelapse mortality (hazard ratio [HR], 2.03; P = .001), overall mortality (HR, 1.48; P = .008), and lower neutrophil (odds ratio [OR], .76; P = .03) and platelet (OR, .76; P = .03) recovery. PBPC from unrelated donors with CD34(+) dose < 6 × 10(6) CD34(+)/kg was also associated with higher nonrelapse (HR, 1.38; P = .02) and overall mortality (HR, 1.20; P = .05). In contrast to reports after myeloablative HCT, CD34(+) dose did not affect relapse or graft-versus-host disease with either donor type. An upper cell dose limit was not associated with adverse outcomes. These data suggest that PBPC CD34(+) doses >4 × 10(6) CD34(+)/kg and >6 × 10(6) CD34(+)/kg are optimal for HLA-matched sibling and unrelated donor HCT, respectively.

    Inflammatory abdominal aortic aneurysms (IAAA) represent 3% to 10% of all abdominal aortic aneurysms. Obstructive uropathy is a well-described feature of IAAAs, but venous complications are unusual secondary to IAAA. The authors report a patient presenting with acute renal failure and deep venous thrombosis secondary to an IAAA. We believe this represents the first case of an IAAA manifesting as combined inferior vena cava compression and associated obstructive uropathy. Successful operative repair was performed. With resolution of the retroperitoneal inflammation, long-term follow-up revealed spontaneous release of both ureteral and caval compression.

    Vascular disorders affecting the kidneys are either acquired or congenital. Included in this category are common multiplicity of renal arteries, the rare arteriovenous malformation, stresses due to fibromuscular disease or atherosclerosis including abdominal aortic aneurysms, arterial thrombosis, venous thrombosis, and infarction. In contrast to the group of cystic and neoplastic kidneys where scintigraphic or pathologic are not diagnostic, scintigraphic or pathologic anatomy in vascular disease is often diagnostic by nuclear medicine techniques. The authors present an interesting case of evaluation of acute renal failure in a patient abdominal aortic aneurysmectomy and axillo-bifemoral bypass graft.

    A prospective phase II multicenter trial was performed with the aim to obtain less than 25% nonrelapse mortality (NRM) after unrelated cord blood transplantation (UCBT) for adults with acute myeloid leukemia (AML) using a reduced-intensity conditioning regimen (RIC) consisting of total body irradiation (2 Gy), cyclophosphamide (50 mg/kg), and fludarabine (200 mg/m(2)). From 2007 to 2009, 79 UCBT recipients were enrolled. Patients who underwent transplantation in first complete remission (CR1) (n = 48) had a higher frequency of unfavorable cytogenetics and secondary AML and required more induction courses of chemotherapy to achieve CR1 compared with the others. The median infused total nucleated cells (TNC) was 3.4 × 10(7)/kg, 60% received double UCBT, 77% were HLA mismatched (4/6), and 40% had major ABO incompatibility. Cumulative incidence of neutrophil recovery at day 60 was 87% and the cumulative incidence of 100-day acute graft-versus-host disease (II to IV) was 50%. At 2 years, the cumulative incidence of NRM and relapse was 20% and 46%, respectively. In multivariate analysis, major ABO incompatibility (P = .001) and TNC (<3.4 × 10(7)/kg; P = .001) were associated with increased NRM, and use of 2 or more induction courses to obtain CR1 was associated with increased relapse incidence (P = .04). Leukemia-free survival (LFS) at 2 years was 35%, and the only factor associated with decreased LFS was secondary AML (P = .04). In conclusion, despite the decreased NRM observed, other RIC regimens with higher myelosuppression should be evaluated to decrease relapse in high-risk AML. (EUDRACT 2006-005901-67).

    Emphysematous pyelonephritis (EP) is a rare form of necrotizing pyelonephritis. It is a life-threatening condition that usually affects patients with diabetes, and a small percentage may be due to urinary tract obstruction. Here, we present the case of an EP caused by urinary tract obstruction without diabetes. A 45-year-old woman presented to the emergency department with fever, chills, and abdominal pain. There was no significant past history. Physical examination depicted bilateral lower abdominal and right flank knocking tenderness. Laboratory exams revealed leukocytosis, neutrophilia, a high C-reactive protein level, and pyuria. Abdominal computerized tomography (CT) showed diffuse gas in the right renal collecting system and dilatation of the right renal pelvis compared to the right side, in addition to multiple millimetric stones located in the right kidney and right ureter. After emergent placement of a percutaneous nephrostomy, she was admitted. Control abdominal CT without contrast revealed the absence of gas, hydronephrosis of the right renal pelvis, and the presence of nephrolithiasis. The patient was discharged 10 days of post-procedure with instructions for follow-up. Emergency physicians need to remain alert about this life-threatening disease and the typical CT findings of this disease to make a timely diagnosis and navigate management. PMID:28250980

    "Open abdomen" is a strategy used to avoid or treat abdominal compartment syndrome. It has reduced mortality both in trauma and non-trauma abdominal catastrophes but also has created a challenging clinical problem. Traditionally, open abdomen is closed in two phases; primarily with a free skin graft and later with a flap reconstruction. A modern trend is to close the abdomen within the initial hospitalization. This requires multi-professional co-operation. Temporary abdominal closure methods, e.g. negative pressure wound therapy alone or combined with mesh-mediated traction, have been developed to facilitate direct fascial closure. Components separation technique, mesh reinforcement or bridging of the fascial defect with mesh and perforator saving skin undermining can be utilized in the final closure if needed. These techniques can be combined. Choice of the treatment depends on the condition of the patient and size of the fascia and skin defect, and the state of the abdominal contents. In this paper we review the literature on the closure of an open abdomen and present the policy used in our institution in the open abdomen situations.

    Chronic abdominal wounds lead to prolonged hospital stays. However, no data exist that describe the experience of persons living with a chronic abdominal wound. The aim of this qualitative study was to explore the experience of persons living with chronic abdominal wounds and elicit their expectations in health professionals. Narrative interviews were conducted with five women and four men. Using content analysis techniques, five categories with one to four subcategories emerged from the data. "Returning to everyday life without a wound" represents the main goal of the participants and is driven by their hope to achieve this outcome. "Everyday life with the wound" illustrates the reality of participants' lives, which is affected by suffering. "The patients' work" demonstrates the component that patients contribute to managing their wound. "The work of primary support persons" shows the importance of the work of people close to the patient. "The work of professionals" includes the expectations that patients have in their caregivers. Teamwork between professionals, patients and primary support persons seems to be an essential condition for the successful healing of an abdominal wound.

    The ability to accurately measure subcutaneous adipose tissue (SAT) and visceral adipose tissue (VAT) from images is important for improved assessment and management of patients with various conditions such as obesity, diabetes mellitus, obstructive sleep apnea, cardiovascular disease, kidney disease, and degenerative disease. Although imaging and analysis methods to measure the volume of these tissue components have been developed [1, 2], in clinical practice, an estimate of the amount of fat is obtained from just one transverse abdominal CT slice typically acquired at the level of the L4-L5 vertebrae for various reasons including decreased radiation exposure and cost [3-5]. It is generally assumed that such an estimate reliably depicts the burden of fat in the body. This paper sets out to answer two questions related to this issue which have not been addressed in the literature. How does one ensure that the slices used for correlation calculation from different subjects are at the same anatomic location? At what anatomic location do the volumes of SAT and VAT correlate maximally with the corresponding single-slice area measures? To answer these questions, we propose two approaches for slice localization: linear mapping and non-linear mapping which is a novel learning based strategy for mapping slice locations to a standardized anatomic space so that same anatomic slice locations are identified in different subjects. We then study the volume-to-area correlations and determine where they become maximal. We demonstrate on 50 abdominal CT data sets that this mapping achieves significantly improved consistency of anatomic localization compared to current practice. Our results also indicate that maximum correlations are achieved at different anatomic locations for SAT and VAT which are both different from the L4-L5 junction commonly utilized.

    Ischemia-reperfusion (IR) injury comprises a significant portion of morbidity and mortality from heart and brain diseases worldwide. This enduring clinical problem has inspired myriad reports in the scientific literature of experimental interventions seeking to elucidate the pathology of IR injury. Elective cardiac surgery presents perhaps the most viable scenario for protecting the heart and brain from IR injury due to the opportunity to condition the organs prior to insult. The physiological parameters for the preconditioning of vital organs prior to insult through mechanical and pharmacological maneuvers have been heavily examined. These investigations have revealed new insights into how preconditioning alters cellular responses to IR injury. However, the promise of preconditioning remains unfulfilled at the clinical level, and research seeking to implicate cell signals essential to this protection continues. Recent discoveries in molecular biology have revealed that gene expression can be controlled through posttranslational modifications, without altering the chemical structure of the genetic code. In this scenario, gene expression is repressed by enzymes that cause chromatin compaction through catalytic removal of acetyl moieties from lysine residues on histones. These enzymes, called histone deacetylases (HDACs), can be inhibited pharmacologically, leading to the de-repression of protective genes. The discovery that HDACs can also alter the function of non-histone proteins through posttranslational deacetylation has expanded the potential impact of HDAC inhibitors for the treatment of human disease. HDAC inhibitors have been applied in a very small number of experimental models of IR. However, the scientific literature contains an increasing number of reports demonstrating that HDACs converge on preconditioning signals in the cell. This review will describe the influence of HDACs on major preconditioning signaling pathways in the heart and brain. PMID

    Acute esophageal necrosis (AEN), also called “black esophagus,” is a condition characterized by circumferential necrosis of the esophagus with universal distal involvement and variable proximal extension with clear demarcation at the gastroesophageal junction. It is an unusual cause of upper gastrointestinal bleeding and is recognized with distinct and striking mucosal findings on endoscopy. The patients are usually older and are critically ill with shared comorbidities, which include atherosclerotic cardiovascular disease, diabetes mellitus, hypertension, chronic renal insufficiency, and malnutrition. Alcoholism and substance abuse could be seen in younger patients. Patients usually have systemic hypotension along with upper abdominal pain in the background of clinical presentation of hematemesis and melena. The endoscopic findings confirm the diagnosis and biopsy is not always necessary unless clinically indicated in atypical presentations. Herein we present two cases with distinct clinical presentation and discuss the endoscopic findings along with a review of the published literature on the management of AEN. PMID:27642529

    A case report is presented of a 37-year-old active duty Navy petty officer with amebic abscess of the liver presenting as acute cholecystitis. He was admitted with severe right upper quadrant pain and a positive Murphy's sign, but sonogram and computed tomography (CT) scan demonstrated an abscess in the right lobe of the liver. "Anchovy paste" material was obtained on percutaneous drainage, and he was placed on metronidazole administration with a tentative diagnosis of amebic abscess. This was confirmed on enzyme-linked immunosorbent assay. Symptoms resolved within a few days, and the abscess progressively decreased in size. Amebic abscess of the liver is discussed, with emphasis on pathogenesis, diagnosis, and treatment. Although uncommon, the condition is still seen in various population groups including the United States military. Difficulty in diagnosis is not unusual, and as in the herein-reported case, amebic abscesses of the liver may be confused with acute cholecystitis and other intra-abdominal infections. Abdominal sonogram and CT examination will identify a process in the liver, but the presence of amebiasis must be confirmed by laboratory studies on serum or contents of the abscess. Amebicidal agents are effective in many cases, but there remain roles for aspiration of the abscess, percutaneous drainage, and even open surgical drainage. Failure to establish an early diagnosis may result in rupture of the abscess, with catastrophic results.

    Background Recruitment of macrophage precursors to the adventitia plays a key role in the pathogenesis of abdominal aortic aneurysms (AAAs), but molecular mechanisms remain undefined. The innate immune signaling molecule CD14 was reported to be upregulated in adventitial macrophages in a murine model of AAA and in monocytes cocultured with aortic adventitial fibroblasts (AoAf) in vitro, concurrent with increased interleukin‐6 (IL‐6) expression. We hypothesized that CD14 plays a crucial role in adventitial macrophage precursor recruitment early during AAA formation. Methods and Results CD14−/− mice were resistant to AAA formation induced by 2 different AAA induction models: aortic elastase infusion and systemic angiotensin II (AngII) infusion. CD14 gene deletion led to reduced aortic macrophage infiltration and diminished elastin degradation. Adventitial monocyte binding to AngII‐infused aorta in vitro was dependent on CD14, and incubation of human acute monocytic leukemia cell line‐1 (THP‐1) monocytes with IL‐6 or conditioned medium from perivascular adipose tissue (PVAT) upregulated CD14 expression. Conditioned medium from AoAf and PVAT induced CD14‐dependent monocyte chemotaxis, which was potentiated by IL‐6. CD14 expression in aorta and plasma CD14 levels were increased in AAA patients compared with controls. Conclusions These findings link CD14 innate immune signaling via a novel IL‐6 amplification loop to adventitial macrophage precursor recruitment in the pathogenesis of AAA. PMID:23537804

    Endoscopic ultrasound (EUS) is a major advance in gastrointestinal endoscopy. EUS, which is invaluable in the diagnosis and staging of gastrointestinal cancer, is now being used in the diagnosis of chronic upper abdominal pain. EUS combined with stimulated biliary drainage (EUS/SBD) aids in the diagnosis of choledocholithiasis, cholecystitis, microlithiasis, and various conditions of the upper gastrointestinal tract. This article describes the EUS/SBD procedure and nursing care. Two case histories illustrating potential benefits to patients are presented.

    Although the way for pain management associated with acute pancreatitis has been searched for, there are not enough medications available for it. The aim of the present study was to investigate the role of bradykinin (BK) in pain related to acute pancreatitis. After repeated injections of caerulein (50 μg/kg and 6 times), mice showed edema in the pancreas, and blood concentrations of pancreatic enzymes (amylase and lipase) were clearly elevated. A histopathological study demonstrated that caerulein caused tissue damage characterized by edema, acinar cell necrosis, interstitial hemorrhage, and inflammatory cell infiltrates. Furthermore, the mRNA levels of interleukin-1β and monocyte chemotactic protein (MCP)-1 were significantly increased in the pancreas of caerulein-treated mice. The sensitivity of abdominal organs as measured by abdominal balloon distension was enhanced in caerulein-injected mice, suggesting that caerulein caused pancreatic hyperalgesia. Moreover, repeated treatment with caerulein resulted in cutaneous tactile allodynia of the upper abdominal region as demonstrated by the use of von Frey filaments, indicating that caerulein-treated mice exhibited referred pain. Under this condition, the mRNA levels of bradykinin B1 receptor (BKB1R) and bradykinin B2 receptor (BKB2R) were significantly increased in the dorsal root ganglion (DRG). Finally, we found that des-Arg⁹-(Leu⁸)-bradykinin (BKB1R antagonist) and HOE-140 (BKB2R antagonist) attenuated the acute pancreatitis pain-like state in caerulein-treated mice. These findings suggest that the upregulation of BK receptors in the DRG may, at least in part, contribute to the development of the acute pancreatitis pain-like state in mice.

    Umbilical venous catheterization has become a widely accepted intravenous route for premature babies. These catheters allow administration of parenteral nutrition and medication and facilitate blood sampling. Besides these benefits, they also have significant potential complications like portal vein thrombosis, infection, vascular or hepatic injury, arrhythmia and sepsis. One of the rare but important complication is extravasation of the fluids due to misplacement of the catheter. The typical symptoms of this condition are sudden deterioration, hepatic enlargement, hematocrit drop, hypotension and abdominal distension. We herein present a premature newborn with unusual acute abdomen findings suggesting a surgical pathology after the extravasation of total parenteral nutrition into the abdomen.

    The Integrated Medical Model (IMM) is a decision support tool that is useful to spaceflight mission planners and medical system designers when assessing risks and optimizing medical systems. The IMM project maintains a database of medical conditions that could occur during a spaceflight. The IMM project is in the process of assigning an incidence rate, the associated functional impairment, and a best and a worst case end state for each condition. The purpose of this work was to develop the IMM Abdominal Injury Module (AIM). The AIM calculates an incidence rate of traumatic abdominal injury per person-year of spaceflight on the International Space Station (ISS). The AIM was built so that the probability of traumatic abdominal injury during one year on ISS could be predicted. This result will be incorporated into the IMM Abdominal Injury Clinical Finding Form and used within the parent IMM model.

    Irritable bowel syndrome (IBS) is a functional gastrointestinal (GI) disorder of unknown etiology. Although relatively common in children, how this condition affects brain structure and function in a pediatric population remains unclear. Here, we investigate brain changes in adolescents with IBS and healthy controls. Imaging was performed with a Siemens 3 Tesla Trio Tim MRI scanner equipped with a 32-channel head coil. A high-resolution T1-weighted anatomical scan was acquired followed by a T2-weighted functional scan. We used a surface-based morphometric approach along with a seed-based resting-state functional connectivity (RS-FC) analysis to determine if groups differed in cortical thickness and whether areas showing structural differences also showed abnormal RS-FC patterns. Patients completed the Abdominal Pain Index and the GI Module of the Pediatric Quality of Life Inventory to assess abdominal pain severity and impact of GI symptoms on health-related quality of life (HRQOL). Disease duration and pain intensity were also assessed. Pediatric IBS patients, relative to controls, showed cortical thickening in the posterior cingulate (PCC), whereas cortical thinning in posterior parietal and prefrontal areas were found, including the dorsolateral prefrontal cortex (DLPFC). In patients, abdominal pain severity was related to cortical thickening in the intra-abdominal area of the primary somatosensory cortex (SI), whereas HRQOL was associated with insular cortical thinning. Disease severity measures correlated with cortical thickness in bilateral DLPFC and orbitofrontal cortex. Patients also showed reduced anti-correlations between PCC and DLPFC compared to controls, a finding that may reflect aberrant connectivity between default mode and cognitive control networks. We are the first to demonstrate concomitant structural and functional brain changes associated with abdominal pain severity, HRQOL related to GI-specific symptoms, and disease-specific measures in

    Patient: Female, 43 Final Diagnosis: Myeloid sarcoma appendicitis Symptoms: Abdominal pain • chills • fever Medication: — Clinical Procedure: Laparoscopic appendectomy, bone marrow biopsy Specialty: Gastroenterology and Hepatology Objective: Rare disease Background: The gastrointestinal tract is a rare site for extramedullary involvement in acute promyelocytic leukemia (APL). Case Report: A 43-year-old female with no past medical history presented complaining of mild abdominal pain, fever, and chills for the past day. On examination, she was tachycardic and febrile, with mild tenderness of her right lower quadrant and without signs of peritoneal irritation. Laboratory examination revealed pancytopenia and DIC, with a fibrinogen level of 290 mg/dL. CT of the abdomen showed a thickened and hyperemic appendix without perforation or abscess, compatible with acute appendicitis. The patient was given IV broad-spectrum antibiotics and was transfused with packed red blood cells and platelets. She underwent uncomplicated laparoscopic appendectomy and bone marrow biopsy, which revealed neo-plastic cells of 90% of the total bone marrow cellularity. Flow cytometry indicated presence of 92.4% of immature myeloid cells with t (15: 17) and q (22: 12) mutations, and FISH analysis for PML-RARA demonstrated a long-form fusion transcript, positive for APL. Appendix pathology described leukemic infiltration with co-expression of myeloperoxidase and CD68, consistent with myeloid sarcoma of the appendix. The patient completed a course of daunorubicin, cytarabine, and all trans-retinoic acid. Repeat bone marrow biopsy demonstrated complete remission. She will follow up with her primary care physician and hematologist/oncologist. Conclusions: Myeloid sarcoma of the appendix in the setting of APL is very rare and it might play a role in the development of acute appendicitis.

    2015-01-01

    The abdominal wall is an integral component of the chest wall. Defects in the ventral abdominal wall alter respiratory mechanics and can impair diaphragm function. Congenital abdominal wall defects also are associated with abnormalities in lung growth and development that lead to pulmonary hypoplasia, pulmonary hypertension, and alterations in thoracic cage formation. Although infants with ventral abdominal wall defects can experience life-threatening pulmonary complications, older children typically experience a more benign respiratory course. Studies of lung and chest wall function in older children and adolescents with congenital abdominal wall defects are few; such investigations could provide strategies for improved respiratory performance, avoidance of respiratory morbidity, and enhanced exercise ability for these children.

    Acute appendicitis often presents as right lower quadrant (RLQ) pain, severe tenderness at the point of McBurny or Lanz, and Blumberg's sign. Scrotal events with appendicitis are very rare. In our case, a 63-year-old Japanese man presented with severe RLQ pain and high fever. Physical examination revealed severe tenderness (including both points of McBurny and Lanz) and Blumberg's sign. The scrotum was slightly swollen and showed local heat with severe testicular pain. Abdominal computed tomography revealed ascites in a pelvic space and the right side of the spermatic cord was swollen. Emergency operation was performed and the final diagnosis was catarrhal appendicitis and acute epididymitis. This is the first report of acute appendicitis concomitant with acute epididymitis.

    The development of new strategies to preserve renal function after acute kidney injury (AKI) is necessary due to limited clinical intervention options. The organ-protective effects of mesenchymal stromal/stem cells (MSCs) and their conditioned medium (CM) have been investigated demonstrating that both separately promoted tubular recovery and ameliorated the outcome of AKI. Nevertheless, strategies to optimise the regenerative potential of both are highly needed. Here we investigated the effects of CM from adipose-derived MSCs (ASCs) preincubated in a hypoxic environment (Hyp). Protective factors were investigated by PCR analysis and a protein array in vitro. The expression of 64 of the 308 proteins assayed was found to be more than two-fold increased after Hyp. CM of Hyp-pretreated ASCs (pCM) was used to enhance regeneration in a mouse model of cisplatin-induced AKI (cisAKI). Renal function was assessed by measurements of markers for AKI and serum cytokine levels. The pCM significantly ameliorated serum creatinine and neutrophil gelatinase-associated lipocalin values, and also the levels of inflammatory cytokines IL-1β and IL-6 in the serum of mice with AKI. Our work clearly showed that a Hyp preconditioning significantly increases the release of protective factors in ASCs and enhances the therapeutic effects of CM in cisAKI in mice.

    Conditional ligands have enabled the high-throughput production of human leukocyte antigen (HLA) libraries that present defined peptides. Immunomonitoring platforms typically concentrate on restriction elements associated with European ancestry, and such tools are scarce for Asian HLA variants. We report 30 novel irradiation-sensitive ligands, specifically targeting South East Asian populations, which provide 93, 63, and 79% coverage for HLA-A, -B, and -C, respectively. Unique ligands for all 16 HLA types were constructed to provide the desired soluble HLA product in sufficient yield. Peptide exchange was accomplished for all variants as demonstrated by an ELISA-based MHC stability assay. HLA tetramers with redirected specificity could detect antigen-specific CD8(+) T-cell responses against human cytomegalovirus, hepatitis B (HBV), dengue virus (DENV), and Epstein-Barr virus (EBV) infections. The potential of this population-centric HLA library was demonstrated with the characterization of seven novel T-cell epitopes from severe acute respiratory syndrome coronavirus, HBV, and DENV. Posthoc analysis revealed that the majority of responses would be more readily identified by our unbiased discovery approach than through the application of state-of-the-art epitope prediction. This flow cytometry-based technology therefore holds considerable promise for monitoring clinically relevant antigen-specific T-cell responses in populations of distinct ethnicity.

Method Semi-structured interviews were conducted with 15 PED clinicians (doctors, emergency nurse practitioners and registered nurses) with varying levels of experience in paediatric emergency medicine (PEM), emergency medicine or paediatrics. Audio-recorded interviews were transcribed and analysed thematically. Results There were clear differences in decision-making approaches between experienced clinicians and junior staff. The latter were more risk adverse, relying heavily on guidelines, set admission criteria, clinical theory and second opinions. This was particularly true for doctors. ‘Informal’ learning was apparent in accounts from less-experienced doctors and nurses, whereby tacit knowledge and risk management played an increasing role in the development of clinical intuition that permitted rapid assessment and treatment of young patients. Conclusions The emergence of intuition entwined with approaches to risk management and the role of these skills in clinical decision making, carry implications for the development of training programmes for clinicians working in PEM. Enhanced training for such groups to permit development of the supplementary skills described in this study could have the ability to improve care delivery and even reduce paediatric admissions.

    1. We studied abdominal muscle responses to positive pressure loads applied suddenly to the external airway while subjects held a constant lung volume against steady pressure. The pre-loading holding pressure was 6 cm H2O, and the loading pressures were 6 or 12 cm H2O lasting for 2 sec. 2. Surface electromyograms (e.m.g.) were recorded over the internal oblique, external oblique, and rectus abdominis muscles. The latency and pattern of the e.m.g. reactions were studied by measuring the raw record for each loading trial, and by averaging the rectified e.m.g. for many trials. 3. No responses were obtained if subjects were instructed not to respond to the loads. When instructed and trained to maintain their pre-load position in spite of the load, a two-phase compensatory response was found. The initial response (phase I) was 100-300 msec in duration; it was followed by a continuous e.m.g. discharge (phase II) which continued to the offset of the pressure load. Subjects were also trained to make a single respiratory effort as quickly as possible after the load onset or after just an auditory stimulus. These were simple reaction time tasks of a traditional kind and the e.m.g. responses elicited were single, brief bursts. 4. For all subjects and experimental conditions the e.m.g. response of the internal oblique occurred first, followed by the external oblique and then the rectus abdominis. For the `maintain position' task, phase I latencies (internal oblique) averaged 66-90 msec for individual subjects, but for single trials with optimal conditions of practice and preparatory intervals these ranged from 42 to 110 msec with a third of the reactions occurring within 50-60 msec. 5. The latencies for reaction time responses to loading were about 6 msec shorter than the phase I latencies. The latency distributions for the two types of responses were similar, and both were affected to the same degree by practice, and changing the length and variability of the preparatory

    Point-of-care abdominal ultrasound (US), which is performed by clinicians at bedside, is increasingly being used to evaluate clinical manifestations, to facilitate accurate diagnoses, and to assist procedures in emergency and critical care. Methods for the assessment of acute abdominal pain with point-of-care US must be developed according to accumulated evidence in each abdominal region. To detect hemoperitoneum, the methodology of a focused assessment with sonography for a trauma examination may also be an option in non-trauma patients. For the assessment of systemic hypoperfusion and renal dysfunction, point-of-care renal Doppler US may be an option. Utilization of point-of-care US is also considered in order to detect abdominal and pelvic lesions. It is particularly useful for the detection of gallstones and the diagnosis of acute cholecystitis. Point-of-case US is justified as the initial imaging modality for the diagnosis of ureterolithiasis and the assessment of pyelonephritis. It can be used with great accuracy to detect the presence of abdominal aortic aneurysm in symptomatic patients. It may also be useful for the diagnoses of digestive tract diseases such as appendicitis, small bowel obstruction, and gastrointestinal perforation. Additionally, point-of-care US can be a modality for assisting procedures. Paracentesis under US guidance has been shown to improve patient care. US appears to be a potential modality to verify the placement of the gastric tube. The estimation of the amount of urine with bladder US can lead to an increased success rate in small children. US-guided catheterization with transrectal pressure appears to be useful in some male patients in whom standard urethral catheterization is difficult. Although a greater accumulation of evidences is needed in some fields, point-of-care abdominal US is a promising modality to improve patient care in emergency and critical care settings.

    The effects of treadmill exercise on components of the cardiovascular (venous return, heart rate, arterial blood pressure) and respiratory systems (minute ventilation, tidal volume, breathing frequency, oxygen consumption, carbon dioxide production) and intra-abdominal pressure were investigated in the Savannah monitor lizard, Varanus exanthematicus B., at 35 degrees C. Compared with resting conditions, treadmill exercise significantly increased lung ventilation, gular pumping, intra-abdominal pressure, mean arterial blood pressure and venous return (blood flow in the post caval vein). However, venous return declines at high levels of activity, and mean arterial pressure and venous return did not attain peak values until the recovery period, immediately following activity. Elevating intra-abdominal pressure in resting lizards (via saline infusion) resulted in significant reductions in venous return when the transmural pressure of the post caval vein became negative (i.e. when intra-abdominal pressure exceeded central venous pressure). Together these results suggest that increments in intra-abdominal pressure compress the large abdominal veins and inhibit venous return. During locomotion, the physical compression of the large abdominal veins may represent a significant limitation to cardiac output and maximal oxygen consumption in lizards.

    Acute pancreatitis is a rare but life-threatening complication in patients with transplanted kidney. The incidence of acute pancreatitis after kidney transplantation ranges from 2% to 7%, with mortality rate between 50 and 100%. We report a case of a female patient aged 46 years, developing an interstitial acute pancreatitis 8 years following a renal transplantation. The specific aethiological factor was not clearly established, although possibility of biliary pancreatitis with spontaneous stone elimination and/or medication-induced pancreatitis remains the strongest. Every patient after renal transplantation with an acute onset of abdominal pain should be promptly evaluated for presence of pancreatitis with a careful application of the most appropriate diagnostic procedure for each individual patient.

    Objective: To describe an adolescent with pathologic aerophagia, a rare condition caused by excessive and inappropriate swallowing of air and to review its treatment and differential diagnoses. Case description: An 11-year-old mentally impaired blind girl presenting serious behavior problems and severe developmental delay with abdominal distension from the last 8 months. Her past history included a Nissen fundoplication. Abdominal CT and abdominal radiographs showed diffuse gas distension of the small bowel and colon. Hirschsprung's disease was excluded. The distention was minimal at the moment the child awoke and maximal at evening, and persisted after control of constipation. Audible repetitive and frequent movements of air swallowing were observed. The diagnosis of pathologic aerophagia associated to obsessive-compulsive disorder and developmental delay was made, but pharmacological treatment was unsuccessful. The patient was submitted to an endoscopic gastrostomy, permanently opened and elevated relative to the stomach. The distention was resolved, while maintaining oral nutrition. Comments: Pathologic aerophagia is a rare self-limiting condition in normal children exposed to high levels of stress and may be a persisting problem in children with psychiatric or neurologic disease. In this last group, the disease may cause serious complications. Pharmacological and behavioral treatments are ill-defined. Severe cases may demand surgical strategies, mainly decompressive gastrostomy. PMID:26100594

    The abdominal aortic aneurysm (AAA) is defined as increasing the diameter of the aorta in more than 50 % of its original size and the infra-renal location is the most common (90 %). AAA disease mainly affects older men and white smokers, and has a male: female ratio of 4:1, as well the diagnosis is rare in women under age 55. Aneurysm rupture is the most common complication and cause of death in the general population, its etiology is unclear, but is commonly associated with atherosclerosis. The AAA do not exhibit rupture and it is usually asymptomatic diagnosed incidentally, however, as the aneurysm grows, appears symptoms such as back pain, abdominal or groin pain, well as palpation of a pulse mass on umbilical and supra-umbilical region. Imaging study such as ultrasound and CT scan are the mainstay of diagnosis. We present a case of 52 years old patient with no history related to the diagnosis, who presented sudden and severe abdominal pain. She was admitted to the emergency room with a diagnosis of acute cholecystitis vs. acute pancreatitis. After ultrasound and CT studies, the diagnosis was a complicated abdominal aortic aneurysm.

  4. Intestinal injury mechanisms after blunt abdominal impact.

    1997-03-01

    Intestinal injury is frequent after non-penetrating abdominal trauma, particularly after modern, high-energy transfer impacts. Under these circumstances, delay in the diagnosis of perforation is a major contributor to morbidity and mortality. This study establishes patterns of intestinal injury after blunt trauma by non-penetrating projectiles and examines relationships between injury distribution and abdominal wall motion. Projectile impacts of variable momentum were produced in 31 anaesthetised pigs to cause abdominal wall motion of varying magnitude and velocity. No small bowel injury was observed at initial impact velocity of less than 40 m/s despite gross abdominal compression. At higher velocity, injury to the small bowel was frequent, irrespective of the degree of abdominal compression (P = 0.00044). Large bowel injury was observed at all impact velocities and at all degrees of abdominal compression. This study confirms the potential for intestinal injury in high velocity, low momentum impacts which do not greatly compress the abdominal cavity and demonstrates apparent differences in injury mechanisms for the small bowel and colon. Familiarity with injury mechanisms may reduce delays in the diagnosis of intestinal perforation in both military and civilian situations.

    Necrotizing fasciitis is a critical illness involving skin and soft tissues, which may develop after blunt abdominal trauma causing abdominal wall hernia and representing a great challenge for physicians. A 52-year-old man was brought to the emergency department after a road accident, presenting blunt abdominal trauma with a large non-reducible mass in the lower-right abdomen. A first, CT showed abdominal hernia without signs of complication. Three hours after ICU admission, he developed hemodynamic instability. Therefore, a new CT scan was requested, showing signs of hernia complication. He was moved to the operating room where a complete transversal section of an ileal loop was identified. Five hours after surgery, he presented a new episode of hemodynamic instability with signs of skin and soft tissue infection. Due to the high clinical suspicion of necrotizing fasciitis development, wide debridement was performed. Following traumatic abdominal wall hernia (TAWH), patients can present unsuspected injuries in abdominal organs. Helical CT can be falsely negative in the early moments, leading to misdiagnosis. Necrotizing fasciitis is a potentially fatal infection and, consequently, resuscitation measures, wide-spectrum antibiotics, and early surgical debridement are required. This type of fasciitis can develop after blunt abdominal trauma following wall hernia without skin disruption.

    This paper presents a method for 3-D segmentation of abdominal aortic aneurysm from computed tomography angiography images. The proposed method is automatic and requires minimal user assistance. Segmentation is performed in two steps. First inner and then outer aortic border is segmented. Those two steps are different due to different image conditions on two aortic borders. Outputs of these two segmentations give a complete 3-D model of abdominal aorta. Such a 3-D model is used in measurements of aneurysm area. The deformable model is implemented using the level-set algorithm due to its ability to describe complex shapes in natural manner which frequently occur in pathology. In segmentation of outer aortic boundary we introduced some knowledge based preprocessing to enhance and reconstruct low contrast aortic boundary. The method has been implemented in IDL and C languages. Experiments have been performed using real patient CTA images and have shown good results.

    Duodenal obstruction caused by abdominal aortic aneurysm was first described by Osler in 1905 and is named "aortoduodenal syndrome." This condition has always been treated by open surgical repair. We report the first case of aortoduodenal syndrome successfully treated by endovascular aneurysm repair. A 74-year-old male patient referred to our hospital complaining postprandial vomit, reporting a consistent weight loss in the latest weeks. Enhanced computed tomography scans showed a small saccular abdominal aortic aneurysm compressing duodenum and inferior vena cava without any other evident pathological finding. As the patient underwent a successful endovascular treatment of the abdominal aortic aneurysm, symptoms immediately resolved so that he started back to feed and progressively gained body weight. Despite aortoduodenal syndrome is generally caused by large abdominal aortic aneurysm, this condition has to be suspected also in case of small abdominal aortic aneurysm. Differently from what has been reported in literature, endovascular aneurysm repair could be effective in the treatment of aortoduodenal syndrome.

    Patients in the intensive care unit (ICU) are at risk of developing of intra abdominal hypertension (IAH) and abdominal compartment syndrome (ACS). Aim: This review seeks to define IAH and ACS, identify the aetiology and presentation of IAH and ACS, identify IAP measurement techniques, identify current management and discuss the implications of IAH and ACS for nursing practice. A search of the electronic databases was supervised by a health librarian. The electronic data bases Cumulative Index of Nursing and Allied Health Literature (CINAHL); Medline, EMBASE, and the World Wide Web was undertaken from 1996- January 2011 using MeSH and key words which included but not limited to: abdominal compartment syndrome, intra -abdominal hypertension, intra-abdominal pressure in adult populations met the search criteria and were reviewed by three authors using a critical appraisal tool. Data derived from the retrieved material are discussed under the following themes: (1) etiology of intra-abdominal hypertension; (2) strategies for measuring intra-abdominal pressure (3) the manifestation of abdominal compartment syndrome; and (4) the importance of nursing assessment, observation and interventions. Intra-abdominal pressure (IAP) and abdominal compartment syndrome (ACS) have the potential to alter organ perfusion and compromise organ function. PMID:24499574

    1998-01-01

    Major technical advances in MR imaging have led to its wider use in the evaluation of abdominal disease. The principle new pulse sequence is the RARE sequence for T2-weighted imaging. Multishot and breath-hold single-shot RARE techniques are now widely used, and both have performed as well as conventional spin-echo imaging with far shorter acquisition times. The most notable improvements have been in the detection and characterization of hepatic lesions. Two liver-specific contrast agents received FDA approval during 1997: SPIO particles or ferumoxide and mangafodipir trisodium, a hepatocyte-specific agent. Both of these agents provide considerable benefit in the detection and characterization of hepatic lesions. Manganese enhancement has also proved useful in MR imaging of the pancreas, although fat-suppressed T1-weighted imaging with dynamic gadolinium enhancement has also yielded results comparable with those of contrast-enhanced CT. MR hydrography, a generic term for static fluid imaging, is another derivative of RARE fast T2-weighted imaging. MRCP, the best known example of MR hydrography, has been rapidly and widely employed as a primary method for imaging the biliary and pancreatic ducts and has become competitive with ERCP. MR vascular imaging, especially portal venography, has been used for noninvasive imaging of portal venous disease in Budd Chiari disease, before placement of transjugular intrahepatic portosystemic shunts, and for pancreatic cancer staging. Finally, the development of conventional phased-array body coils and endorectal coils has enabled high-quality MR imaging of perirectal disease (including Crohn disease, fistula in ano, and postpartum sphincter dysfunction). Future abdominal applications of MR imaging will involve second-generation MR interventional techniques, including use of open systems, functional or diffusion-weighted imaging exploiting the molecular activity of tissues, and virtual MR endoscopy.

    Abdominal wall defects requiring soft tissue coverage can be either partial-thickness defects or full-thickness composite defects. Soft tissue flap reconstruction offers significant advantages in defects that cannot be closed primarily. Flap reconstruction is performed in a single-stage procedure obviating chronic wound management. If the defect size exceeds the availability of local soft tissue for coverage, regional pedicled flaps can be delivered into the abdominal wall while maintaining blood supply from their donor site. Microsurgical free tissue transfer increases the capacity to provide soft tissue coverage for abdominal wall defects that are not amenable to either local or regional flap coverage.

    A 34-year-old woman, gravida 6 with 10 weeks of gestation was admitted because of abdominal pain and fainting. On physical examination she had hypotension, was pale with abdominal tenderness and guarding. Culdocentesis yielded unclotted blood. Immediate laparotomy was performed, because a diagnosis of ectopic pregnancy was made. About 2,500 ml of fresh blood was found in the abdominal cavity. Appendicular artery tear caused active arterial bleeding. The torn appendicular artery was observed to be the consequence of perforated appendicitis, which, in turn, was caused by a faecalith. Appendectomy was performed and she made a good recovery.

  13. Automatic segmentation of abdominal vessels for improved pancreas localization

    Accurate automatic detection and segmentation of abdominal organs from CT images is important for quantitative and qualitative organ tissue analysis as well as computer-aided diagnosis. The large variability of organ locations, the spatial interaction between organs that appear similar in medical scans and orientation and size variations are among the major challenges making the task very difficult. The pancreas poses these challenges in addition to its flexibility which allows for the shape of the tissue to vastly change. Due to the close proximity of the pancreas to numerous surrounding organs within the abdominal cavity the organ shifts according to the conditions of the organs within the abdomen, as such the pancreas is constantly changing. Combining these challenges with typically found patient-to-patient variations and scanning conditions the pancreas becomes harder to localize. In this paper we focus on three abdominal vessels that almost always abut the pancreas tissue and as such useful landmarks to identify the relative location of the pancreas. The splenic and portal veins extend from the hila of the spleen and liver, respectively, travel through the abdominal cavity and join at a position close to the head of the pancreas known as the portal confluence. A third vein, the superior mesenteric vein, anastomoses with the other two veins at the portal confluence. An automatic segmentation framework for obtaining the splenic vein, portal confluence and superior mesenteric vein is proposed using 17 contrast enhanced computed-tomography datasets. The proposed method uses outputs from the multi-organ multi-atlas label fusion and Frangi vesselness filter to obtain automatic seed points for vessel tracking and generation of statistical models of the desired vessels. The approach shows ability to identify the vessels and improve localization of the pancreas within the abdomen.

    As an alternative to open aneurysm repair, emergency endovascular aortic repair (EVAR) has emerged as a promising technique for ruptured abdominal aortic aneurysm (rAAA) within the last decade. The aim of this retrospective study is to present early and late outcomes of patients treated with EVAR for rAAA. Twenty-two patients (5 women, 17 men; mean age, 74 years) underwent EVAR for rAAA between November 2000 and April 2006. Diagnostic multislice computed tomography angiography was performed prior to stent-graft repair to evaluate anatomical characteristics and for follow-up examinations. Periprocedural patient characteristics and technical settings were evaluated. Mortality rates, hospital stay, and early and late complications, within a mean follow-up time of 744 {+-} 480 days, were also assessed. Eight of 22 patients were hemodynamically unstable at admission. Stent-graft insertion was successful in all patients. The total early complication rate was 54%, resulting in a 30-day mortality rate of 23%. The median intensive care unit stay was 2 days (range, 2-48 days), and the median hospital stay was 16 days (range, 9-210 days). During the follow-up period, three patients suffered from stent-graft-related complications. The overall mortality rate in our study group was 36%. EVAR is an acceptable, minimally invasive treatment option in patients with acute rAAA, independent of the patient's general condition. Short- and long-term outcomes are definitely comparable to those with open surgical repair procedures.

    We treated patients under age 50 years with 131I-anti-CD45 antibody combined with fludarabine and 2 Gy total body irradiation to create an improved hematopoietic cell transplantation (HCT) strategy for advanced acute myeloid leukemia or high-risk myelodysplastic syndrome patients. Fifteen patients received 332–1,561 mCi of 131I, delivering an average of 27 Gy to bone marrow, 84 Gy to spleen, and 21 Gy to liver. Although a maximum dose of 28 Gy was delivered to the liver, no dose-limiting toxicity was observed. Marrow doses were arbitrarily capped at 43 Gy to avoid radiation-induced stromal damage; however no graft failure or evidence of stromal damage was observed. Twelve patients (80%) developed Grade II graft-versus-host disease (GVHD), one patient developed Grade III GVHD, and no patients developed Grade IV GVHD during the first 100 days after HCT. Of the 12 patients with chronic GVHD data, 10 developed chronic GVHD, generally involving the skin and mouth. Six patients (40%) are surviving after a median of 5.0 years (range, 4.2 to 8.3 years). The estimated survival at 1 year was 73% among the 15 treated patients. Eight patients relapsed, 7 of whom subsequently died. The median time to relapse among these 8 patients was 54 days (range, 26 to 1364 days). No cases of non-relapse mortality were observed in the first year after transplant. However, two patients died in remission from complications of chronic GVHD and cardiomyopathy, at 18 months and 14 months after transplant, respectively. This study suggests that patients may tolerate myeloablative doses >28 Gy delivered to the liver using 131I-anti-CD45 antibody in addition to standard reduced intensity conditioning. Moreover, the arbitrary limit of 43 Gy to the marrow may be unnecessarily conservative, and continued escalation of targeted radioimmunotherapy doses may be feasible to further reduce relapse.

    We retrospectively evaluated early and long-term complications of an intensified conditioning regimen consisting of busulfan and etoposide in combination with either nimustine hydrochloride (ACNU) (BVA regimen, n = 18) or melphalan (BVL regimen, n = 34) in 52 children with acute leukemia or non-Hodgkin's lymphoma. With a median follow-up of 13.2 years after the BVA regimen and 8.1 years after the BVL regimen, 61% and 76% of patients, respectively, are in continuous complete remission. Transplantation-related mortality was 17% and 6% after the BVA and BVL regimens, respectively, and the corresponding relapse rates were 17% and 15%. The most common and severe toxicity was pulmonary complication in the BVA regimen, which was seen in 67% of patients and was life-threatening in 20%. Thirty-three percent of patients after the BVA regimen and 24% after BVL died of relapse or disease progression (n = 9), interstitial pneumonia (n = 2), fungal pneumonia (n = 1), or chronic graft-versus-host disease (n = 2). One of the long-term survivors developed secondary leukemia. A significant decrease in the height standard deviation score of more than 2 SD from diagnosis to the last follow-up was seen in 17% of the patients, with hypothyroidism in 15%, and alopecia in 42%. Because our experience is limited to a small heterogeneous population of patients who mainly underwent transplantation in the first remission, we cannot draw conclusions on the treatment's effectiveness. The BVL regimen is tolerable, however, because no regimen-related death was observed, whereas the BVA regimen is not recommended because of the high incidence of pulmonary complications. The effectiveness of the BVL regimen requires further study.

    Mesenchymal stromal cells (MSCs) or their media (MSC-M) were reported to reverse acute lung injury (ALI)-induced decrease of alveolar fluid clearance. To determine the mechanisms by which MSC-M exert their beneficial effects, an in vitro model of alveolar epithelial injury was created by exposing primary rat alveolar epithelial cells (AECs) to hypoxia (3% O2) plus cytomix, a combination of IL-1β, TNF-α, and IFN-γ. MSC-M were collected from human MSCs exposed for 12 h to either normoxia (MSC-M) or to hypoxia plus cytomix (HCYT-MSC-M). This latter condition was used to model the effect of alveolar inflammation and hypoxia on paracrine secretion of MSCs in the injured lung. Comparison of paracrine soluble factors in MSC media showed that the IL-1 receptor antagonist and prostaglandin E2 were markedly increased while keratinocyte growth factor (KGF) was twofold lower in HCYT-MSC-M compared with MSC-M. In AECs, hypoxia plus cytomix increased protein permeability, reduced amiloride-sensitive short-circuit current (AS-Isc), and also decreased the number of α-epithelial sodium channel (α-ENaC) subunits in the apical membrane. To test the effects of MSC media, MSC-M and HCYT-MSC-M were added for an additional 12 h to AECs exposed to hypoxia plus cytomix. MSC-M and HCYT-MSC-M completely restored epithelial permeability to normal. MSC-M, but not HCYT-MSC-M, significantly prevented the hypoxia plus cytomix-induced decrease of ENaC activity and restored apical α-ENaC channels. Interestingly, KGF-deprived MSC-M were unable to restore amiloride-sensitive sodium transport, indicating a possible role for KGF in the beneficial effect of MSC-M. These results indicate that MSC-M may be a preferable therapeutic option for ALI.

    Hyperglycemia negatively affects cardiovascular variables that are also adversely affected by increased geomagnetic activity. It is likely that geomagnetic storms (GS) could have a stronger negative impact on these patients. We analyzed data on 1548 randomly selected patients with acute coronary syndrome (ACS) who were admitted inpatient treatment in Kaunas city, during 2000-2003. We evaluated the associations of GS, solar proton events (SPE), and high-speed solar wind (HSSW) (solar wind speed ≥600 km/s) with the risk of ACS in patients with diabetes mellitus (DM) and the metabolic syndrome (MS) by using logistic regression with categorical predictors. During days of HSSW, the risk of ACS in DM patients increased by 1.95 times (OR = 1.95, 95 % CI 1.36-2.79) as compared to days without either of these events or 2 days prior to or after them. In the multivariate model, the risk of ACS in DM patients was associated with days of HSSW and 1-2 days after (OR = 1.40, 95 % CI 1.01-1.93), with days of GS lasting >1 day and occurring on days of HSSW or 1-2 days after (OR = 2.31, 95 % CI 1.28-4.17), and with the onset of SPE (OR = 2.72 (1.09-6.83)). The risk of ACS in MS patients was associated with days of GS and 1-2 days prior or after GS (OR = 1.31 (1.00-1.73)); an additional impact was established if these days coincided with days of HSSW or 1-2 days before (OR = 2.16 (1.39-3.35)). These findings suggest that not only GS but also HSSW and changes in space weather conditions prior to SPE affect the human cardiovascular system.

    Acute hypocalcaemia is a medical emergency that can have catastrophic implications like tetany, seizures, cardiac arrythmias or laryngospasm if left untreated. We are presenting a case of a 30-year-old female patient undergoing total abdominal hysterectomy with bilateral salpingoopherectomy under spinal anaesthesia. She developed unexpected bilateral carpal spasm intraoperatively which was promptly diagnosed and successfully managed with intravenous calcium administration. We conclude that the anaesthetist should be aware of the clinical presentation of acute hypocalcaemia, its causes and emergency management in the perioperative period to prevent any adverse outcomes.

    Acute aortic syndromes, encompassing intramural hematoma, penetrating ulcer, and pseudoaneurysm, are best demonstrated by angiographic CT and magnetic resonance imaging. These imaging modalities provide an accurate evaluation and allow timely therapies of these frequently symptomatic lesions, thus reducing their morbidity and mortality. The inflammatory pathogenesis of these acute aortic syndromes may exhibit positive PET findings predictive of prognosis and outcomes of these vascular events. The authors present a case of PET/CT imaging showing asymptomatic intramural hematomas with penetrating ulcer and saccular pseudoaneurysm of the proximal abdominal aorta.

    The Abdominal gene is a member of the single homeotic complex of the beetle, Tribolium castaneum. An integrated developmental genetic and molecular analysis shows that Abdominal is homologous to the abdominal-A gene of the bithorax complex of Drosophila. abdominal-A mutant embryos display strong homeotic transformations of the anterior abdomen (parasegments 7-9) to PS6, whereas developmental commitments in the posterior abdomen depend primarily on Abdominal-B. In beetle embryos lacking Abdominal function, parasegments throughout the abdomen are transformed to PS6. This observation demonstrates the general functional significance of parasegmental expression among insects and shows that the control of determinative decisions in the posterior abdomen by homeotic selector genes has undergone considerable evolutionary modification.

    2014-01-01

    In this Topic Highlight, the causes, diagnosis, and treatment of acute pancreatitis in children are discussed. Acute pancreatitis should be considered during the differential diagnosis of abdominal pain in children and requires prompt treatment because it may become life-threatening. The etiology, clinical manifestations, and course of acute pancreatitis in children are often different than in adults. Therefore, the specific features of acute pancreatitis in children must be considered. The etiology of acute pancreatitis in children is often drugs, infections, trauma, or anatomic abnormalities. Diagnosis is based on clinical symptoms (such as abdominal pain and vomiting), serum pancreatic enzyme levels, and imaging studies. Several scoring systems have been proposed for the assessment of severity, which is useful for selecting treatments and predicting prognosis. The basic pathogenesis of acute pancreatitis does not greatly differ between adults and children, and the treatments for adults and children are similar. In large part, our understanding of the pathology, optimal treatment, assessment of severity, and outcome of acute pancreatitis in children is taken from the adult literature. However, we often find that the common management of adult pancreatitis is difficult to apply to children. With advances in diagnostic techniques and treatment methods, severe acute pancreatitis in children is becoming better understood and more controllable. PMID:25400985

    2016-01-01

    Eosinophilic gastroenteritis is a rare inflammatory disorder of the gastrointestinal tract with an estimated prevalence of one in 100,000. The typical presentation consists of vague gastrointestinal symptoms with the mucosal involvement of the digestive system. Rarely, it presents as eosinophilic ascites. We report the case of a 22-year-old female who presented with acute onset abdominal pain and ascites. The laboratory studies were remarkable for eosinophilia and the ascitic fluid demonstrated high eosinophilic counts. Push enteroscopy with biopsy supported the diagnosis of eosinophilic gastroenteritis, with likely serosal involvement. Other differential diagnoses were excluded. A prednisone taper along with dietary treatment was initiated. We report complete resolution of symptoms two weeks following the initiation of therapy. Nine months later, she remains asymptomatic without recurrence of ascites. PMID:27843730

    1995-01-01

    Postoperative necrotizing fasciitis of the anterior abdominal wall is a serious and life-endangering complication of an acute progressive synergistic infective process. There is an absolute increase in its incidence rate attributable to a number of situations in modern life. Morphological and clinical studies are carried out on personal case material of 28 patients, followed up over a 3-year period. The presence of aerobic-anaerobic mixed polyinfection, consisting of average 3.75 bacterial species of which 1.43 aerobes and 2.32 anaerobes, is demonstrated microbiologically. Of the latter non-spore-bearing obligate anaerobes predominate among which B fragillis is the most common. As shown by the study, the process is characterized by slow initial course with ensuring rapid spreading by neighbourhood. The process reveals all signs of a mixed aerobic-anaerobic polyinfection, thereby necessitating subordination of both antibiotic therapy and surgical tactics to the latter.

    1993-01-01

    Approximately 10 per cent of abdominal aneurysms have an excessively thick wall that sometimes involve duodenum, cava or colon by an inflammatory process. Between February 1986 and December 1992, 147 patients with abdominal aortic aneurysm (AAA) were treated surgically and in 13 (8.8%) the aneurysms were found to be inflammatory. Their mean age was 67.3 years (70.1 years in non inflammatory group) and all were symptomatics initially (abdominal pain in 53%, rupture in 23%, mass in 15%). The operative mortality for elective resection was 37% in patients with inflammatory abdominal aortic aneurysms (IAAA) decreasing to 9% in the AAA group without inflammatory involvement. We conclude that surgery is indicated in these patients to prevent rupture and to hasten the subsidense of inflammatory process ever with postoperative morbi-mortality increased.

    Abdominal migraines present with debilitating symptoms in adolescence. At our institution, the gastroenterology, neurology, and autonomic departments collaborated in treating patients with such presentations. This case series describes 6 patients who were given intravenous dihydroergotamine (DHE) for presumed abdominal migraines. DHE was only used when other agents like amitriptyline, verapamil, topiramate, or depakote had proved ineffective. DHE was started at 0.5 mg dose and on average 7 to 9 mg were given on each hospitalization. Patient ages ranged from 13 to 19 years with the majority being female. One patient did not respond to treatment. One patient was admitted 4 times for symptoms of abdominal migraines resolving with DHE. The average time between symptom relapse was about 5 to 12 months. Five of our 6 patients responded to the infusion without significant side effects. Based on these case series, DHE may be a treatment option in children with intractable abdominal migraine.

  12. A Review of the Predictive Role of Plasma D-Lactate Level in Acute Appendicitis: A Myth or Truth?

    PubMed Central

    Unverir, Pinar; Karcioglu, Ozgur

    2011-01-01

    Acute appendicitis (AA) is a common condition which warrants emergency surgery. Detailed history, physical exam, and laboratory findings are often nonspecific in suspected patients. There is substantial evidence to indicate that plasma levels of D-lactate were useful to establish a diagnosis of AA in the medical literature. It has been suggested that it is useful for patients with abdominal pain, especially patients with perforated AA. This paper is designed to highlight the value of D-lactate biomarker in establishing a diagnosis of AA. Based on the literature, it is not helpful for a decision of operation in patients with AA. According to the results of the studies, laboratory involvement was observed between plasma D-lactate level and the final diagnosis of AA, particularly in perforated appendices. It can be considered for routine use in patients with undifferentiated abdominal pain in the emergency department setting. PMID:23724288

  13. Acute cerebellar ataxia, acute cerebellitis, and opsoclonus-myoclonus syndrome.

    PubMed

    2012-11-01

    Acute cerebellar ataxia and acute cerebellitis represent a process characterized by parainfectious, postinfectious, or postvaccination cerebellar inflammation. There is considerable overlap between these entities. The mildest cases of acute cerebellar ataxia represent a benign condition that is characterized by acute truncal and gait ataxia, variably with appendicular ataxia, nystagmus, dysarthria, and hypotonia. It occurs mostly in young children, presents abruptly, and recovers over weeks. Neuroimaging is normal. Severe cases of cerebellitis represent the other end of the spectrum, presenting with acute cerebellar signs often overshadowed by alteration of consciousness, focal neurological deficits, raised intracranial pressure, hydrocephalus, and even herniation. Neuroimaging is abnormal and the prognosis is less favorable than in acute cerebellar ataxia. Acute disseminated encephalomyelitis may be confused with acute cerebellitis when the clinical findings are predominantly cerebellar, but lesions on neuroimaging are usually widespread. Paraneoplastic opsoclonus-myoclonus syndrome is often initially misdiagnosed as acute cerebellar ataxia, but has very specific features, course, and etiopathogensis.

    Stab wounds (SW) to the abdomen traditionally require urgent exploration when associated with shock, evisceration, or peritonitis. Hemodynamically stable patients without evisceration may benefit from serial exams even with peritonitis. We compared patients taken directly to the operating room with abdominal SWs (ED-OR) to those admitted for serial exams (ADMIT). We retrospectively reviewed hemodynamically stable patients presenting with any abdominal SW between January 2000 and December 2012. Exclusions included evidence of evisceration, systolic blood pressure ≤110 mm Hg, or blood transfusion. NON-THER was defined as abdominal exploration without identification of intra-abdominal injury requiring repair. Of 142 patients included, 104 were ED-OR and 38 were ADMIT. When ED-OR was compared with ADMIT, abdominal Abbreviated Injury Score was higher (2.4 vs 2.1; P = 0.01) and hospital length of stay was longer (4.8 vs 3.3 days; P = 0.04). Incidence of NON-THER was higher in ED-OR cohort (71% vs 13%; P ≤ 0.001). In a regression model, ED-OR was a predictor of NON-THER (adjusted odds ratio 16.6; P < 0.001). One patient from ED-OR expired after complications from NON-THER. There were no deaths in the ADMIT group. For those patients with abdominal SWs who present with systolic blood pressure ≥110 mm Hg, no blood product transfusion in the emergency department and lacking evisceration, admission for serial abdominal exams may be preferred regardless of abdominal exam.

    Summary Background: The acute abdomen accounts for up to 40% of all emergency surgical hospital admissions and a large proportion are secondary to gastrointestinal perforation. Studies have shown the superiority of the abdominal CT over upright chest radiographs in demonstrating free intraperitoneal air. Spontaneous perforated pyometra is a rare cause of the surgical acute abdomen with free intraperitoneal air. Only 38 cases have been reported worldwide. Case Report: We report 2 cases of spontaneously perforated pyometra in our hospital’s general surgery department. Both underwent exploratory laparotomy: one had a total hysterectomy and bilateral salpingo-oophorectomy, while the other had an evacuation of the uterine cavity, primary repair of uterine perforation and a peritoneal washout. A literature search was conducted and all reported cases reviewed in order to describe the clinical presentations and management of the condition. Of the 40 cases to date, including 2 of our cases, the most common presenting symptoms were abdominal pain (97.5%), fever (37.5%) and vomiting (25.0%). The main indication for exploratory laparotomy was pneumoperitoneum (97.5%). Conclusions: Pyometra is an unusual but serious condition in elderly women presenting with an acute abdomen. A high index of suspicion is needed to make the appropriate diagnosis. PMID:23569488

    Objective: To identify the association of dietary, socioeconomic factors, sedentary behaviors and maternal nutritional status with abdominal obesity in children. Methods: A cross-sectional study with household-based survey, in 36 randomly selected census tracts in the city of Santos, SP. 357 families were interviewed and questionnaires and anthropometric measurements were applied in mothers and their 3-10 years-old children. Assessment of abdominal obesity was made by maternal and child's waist circumference measurement; for classification used cut-off points proposed by World Health Organization (1998) and Taylor et al. (2000) were applied. The association between variables was performed by multiple logistic regression analysis. Results: 30.5% of children had abdominal obesity. Associations with children's and maternal nutritional status and high socioeconomic status were shown in the univariate analysis. In the regression model, children's body mass index for age (OR=93.7; 95%CI 39.3-223.3), female gender (OR=4.1; 95%CI 1.8-9.3) and maternal abdominal obesity (OR=2.7; 95%CI 1.2-6.0) were significantly associated with children's abdominal obesity, regardless of the socioeconomic status. Conclusions: Abdominal obesity in children seems to be associated with maternal nutritional status, other indicators of their own nutritional status and female gender. Intervention programs for control of childhood obesity and prevention of metabolic syndrome should consider the interaction of the nutritional status of mothers and their children. PMID:26298655

    2011-01-01

    An arterial aneurysm is defined as a focal dilation of a blood vessel with respect to the original artery. The risk of abdominal aortic aneurysms (AAAs) increases dramatically in the presence of the following factors: age older than 60 years, smoking, hypertension and Caucasian ethnicity. The likelihood that an aneurysm will rupture is influenced by the aneurysm size, expansion rate, continued smoking and persistent hypertension. The majority of AAAs are asymptomatic and are detected as an incidental finding on ultrasonography, abdominal computed tomography or magnetic resonance imaging performed for other purposes. It can also present with abdominal pain or complications such as thrombosis, embolization and rupture. Approximately 30% of asymptomatic AAAs are discovered as a pulsatile abdominal mass on routine physical examination. Abdominal ultrasonography is considered the screening modality of choice for detecting AAAs because of its high sensitivity and specificity, as well as its safety and relatively lower cost. The decision to screen for AAAs is challenging. The United States Preventive Services Task Force recommended that men between the age of 65 to 75 years who have ever smoked should be screened at least once for AAAs by abdominal ultrasonography. Management options for patients with an asymptomatic AAA include reduction of risk factors such as smoking, hypertension and dyslipidemia; medical therapy with beta-blockers; watchful waiting; endovascular stenting; and surgical repair depending on the size and expansion rate of the aneurysm and underlying comorbidities.

    PubMed

    Simon, Neil G; Herkes, Geoffrey K

    2011-09-01

    The porphyrias are diseases characterised by accumulation of porphyrins and porphyrin precursors owing to enzymatic deficiencies of the haem synthetic pathway. In the acute hepatic porphyrias accumulation of porphyrin precursors, in particular delta-aminolaevulinic acid (ALA), cause dysfunction of the central, peripheral and autonomic nervous systems. This leads to the characteristic clinical findings of abdominal pain, neuropsychiatric symptoms and neuropathy. The exact pathogenic mechanism is not clear but evidence to date suggests both direct toxic effects of ALA and intracellular metabolic derangement contribute to the neurologic disorders. This review explores the mechanisms of neural dysfunction in the acute porphyrias and the resultant clinical features of an acute attack.

    Introduction. Acute adrenal crisis in relation to nasal steroid overuse has been reported very scantly in English medical literature and remains an underdiagnosed condition. Case presentation. A 55 year-old male presented with altered mental status, retrograde amnesia, fluid refractory hypotension, abdominal pain, fever, and chest pain. Physical examination revealed amnesia, bradypsychia, tachycardia, decreased muscle tone and hyporeflexia. Overuse of nasal steroid was suspected by history. Random early morning cortisol level was < 0.2 mcg/dL. The patient was started on hydrocortisone and within 24 hours he had a full recovery. Conclusion. This one-of-a-kind case describes acute adrenal crisis secondary to withdrawal from inhaled nasal corticosteroids overuse in a patient with particular risk factors. Prevention and early recognition of this disorder can significantly reduce its morbidity and mortality.

    Gastric volvulus is a rare and life-threatening condition that involves the abnormal rotation of the stomach around its axis by more than 180°. The association between acute gastric volvulus and atrial fibrillation with rapid ventricular response is rare with only few cases that have been reported. Our patient was an 86-year-old female who presented with upper abdominal pain, distension, nausea, and shortness of breath. Clinical and laboratory workup revealed acute gastric volvulus with diaphragmatic hernia. On presentation, she was also in atrial fibrillation with rapid ventricular response. She was successfully treated by laparotomy with reduction of the gastric volvulus and repair of the diaphragmatic hernia, with significant improvement. PMID:28373916

    Chronic abdominal wall pain is a well-documented complication of abdominal surgery. However, abdominal wall complex regional pain syndrome (CRPS) is a rare medical condition. We present a case of abdominal wall CRPS and its treatment with peripheral nerve field stimulation (PNfS). A 34-year-old female presented with right periumbilical pain for 2 years. She developed burning, sharp and stabbing pain with allodynia (extremely sensitive to wind and light touch) and erythema or pallor 2 weeks after an exploratory appendectomy. The extensive evaluation ruled out the underlining pathology. After she failed conservative therapies, she underwent a 7-day trial of thoracic spinal cord stimulation (SCS) and abdominal wall PNfS. Thoracic SCS failed to provide pain relief; however, PNfS provided significant relief (>90%) of burning sensation. It has now been 5 years since the PNfS was implanted and she continues to demonstrate substantial pain relief. PMID:28044002

  5. Many faces of angioedema: focus on the diagnosis and management of abdominal manifestations of hereditary angioedema.

    PubMed

    Nzeako, Ugochukwu C; Longhurst, Hilary J

    2012-04-01

    Angioedema of the intestinal tract is an infrequent but well-described cause of abdominal pain that can occur because of inherited, acquired, allergic, or drug-induced causes. Hereditary angioedema (HAE) is a genetic disorder that causes recurrent attacks of severe edema of various body parts, including the intestinal tract. Moderate to severe abdominal pain occurs in 43-93% of such attacks due to intestinal edema. Laryngeal edema is a potentially life-threatening manifestation. Failure to recognize and diagnose HAE or other causes of intestinal angioedema can lead to years of delay in diagnosis, and in the case of HAE, often to unnecessary abdominal surgeries. Recognizing the typical history of recurrent attacks of abdominal pain, oropharyngeal/laryngeal angioedema or cutaneous angioedema, family history of similar symptoms, association of attacks with stress or menses, and exacerbation of attacks after administration of estrogens or angiotensin-converting enzyme inhibitors will increase diagnostic accuracy. Interdisciplinary treatment is often necessary after the diagnosis of HAE, first with acute management in the emergency room or the intensive care unit, followed by either drug prophylaxis against future attacks using a C1-esterase inhibitor concentrate or attenuated androgens and discontinuation of medications known to trigger attacks. Newer drugs approved for treatment of acute attacks may have future roles in the prevention of attacks if further studies support their efficacy. Gastroenterologists in particular should maintain a high index of suspicion for the possibility of HAE or other causes of intestinal angioedema in patients with a history of recurrent abdominal pain.

    We describe the case of a young man who presented with abdominal pain, vomiting and acute symmetric peripheral polyneuropathy. He was noted to have high anion gap metabolic acidosis with high lactate levels and persistently high arterial and venous pO2 values. The cerebrospinal fluid was acellular with a high protein and the nerve conduction study was consistent with axonal sensorimotor neuropathy. His clinical condition deteriorated rapidly despite full supportive care and he subsequently died of multiorgan failure. An extensive workup for various infectious, autoimmune and other possible aetiologies was carried out to identify the underlying cause for his fulminant illness. All diagnostic workup was non-conclusive except for a significantly elevated serum aluminium level. We have discussed the possibility of aluminium phosphide poisoning in view of the clinical presentation. PMID:24899008

  8. Reconstruction of complex abdominal wall defects.

    PubMed

    Leppäniemi, A; Tukiainen, E

    2013-01-01

    Complex abdominal wall defects refer to situations where simple ventral hernia repair is not feasible because the defect is very large, there is a concomitant infection or failed previous re-pair attempt, or if there is not enough original skin to cover the repair. Usually a complex abdominal wall repair is preceded by a period of temporary abdominal closure where the short-term aims include closure of the catabolic drain, protection of the viscera and preventing fistula formation, preventing bowel adherence to the abdominal wall, and enabling future fascial and skin closure. Currently the best way to achieve these goals is the vacuum- and mesh-mediated fascial traction method achieving close to 90% fascial closure rates. The long-term aims of an abdominal closure following a planned hernia strategy include intact skin cover, fascial closure at midline (if possible), good functional outcome with innervated abdominal musculature, no pain and good cosmetic result. The main methods of abdominal wall reconstruction include the use of prosthetic (mesh) or autologous material (tissue flaps). In patients with original skin cover over the fascial defect (simple ventral hernia), the most commonly used method is hernia repair with an artificial mesh. For more complex defects, our first choice of reconstruction is the component separation technique, sometimes combined with a mesh. In contaminated fields where component separation alone is not feasible, a combination with a biological mesh can be used. In large defects with grafted skin, a free TFL flap is the best option, sometimes reinforced with a mesh and enhanced with components separation.

    Teratoma-like formation addresses a critical safety concern for the potential utility of induced pluripotent stem cells (iPSCs). Therefore, therapy utilizing iPSC-derived conditioned medium (iPSC-CM) for acute kidney injury (AKI) has attracted substantial interest. A recent study showed that iPSC-CM effectively alleviated ventilator-induced lung injury in rats. It prompts us to assess the therapeutic effects of iPSC-CM on ischemic AKI. First, we assessed the changes in renal function and tubular cell apoptosis by intraperitoneal administration of iPSC-CM to ischemia-reperfusion (I/R) rats. Second, we explored the oxidative stress-related pathway in the apoptosis of renal tubular cells subjected to hypoxia-reoxygenation (H/R). Administration of iPSC-CM significantly improved renal function and protected tubular cells against apoptosis in rats with I/R-AKI, and the optimal effect was observed at the 50-fold concentrated iPSC-CM. iPSC-CM also mitigated the H/R-induced apoptosis of NRK-52E cells in vitro. Reactive oxygen species (ROS) production was augmented in kidneys following I/R and in NRK-52E cells subjected to H/R. Meanwhile, expressions of phosphorylated p38 MAPK, TNF-α, and cleaved caspase 3 and NF-κB activity were consistently increased in vivo and in vitro. Following administration of iPSC-CM, ROS production was abolished, and inflammatory cytokine expression was significantly suppressed. Annexin V-propidium iodide flow cytometry and in situ TUNEL assay further showed that iPSC-CM markedly attenuated H/R- or I/R-induced tubular cell apoptosis. Intriguingly, treatment with iPSC-CM significantly improved the survival of rats with I/R-induced AKI. iPSC-CM represents a favorable source of stem cell-based therapy and may serve as a potential therapeutic strategy for kidney repair in ischemic AKI.

    We treated patients under age 50 years with iodine-131 ((131)I)-anti-CD45 antibody combined with fludarabine and 2 Gy total body irradiation to create an improved hematopoietic cell transplantation (HCT) strategy for advanced acute myeloid leukemia or high-risk myelodysplastic syndrome patients. Fifteen patients received 332 to 1561 mCi of (131)I, delivering an average of 27 Gy to bone marrow, 84 Gy to spleen, and 21 Gy to liver. Although a maximum dose of 28 Gy was delivered to the liver, no dose-limiting toxicity was observed. Marrow doses were arbitrarily capped at 43 Gy to avoid radiation-induced stromal damage; however, no graft failure or evidence of stromal damage was observed. Twelve patients (80%) developed grade II graft-versus-host disease (GVHD), 1 patient developed grade III GVHD, and no patients developed grade IV GVHD during the first 100 days after HCT. Of the 12 patients with chronic GVHD data, 10 developed chronic GVHD, generally involving the skin and mouth. Six patients (40%) are surviving after a median of 5.0 years (range, 4.2 to 8.3 years). The estimated survival at 1 year was 73% among the 15 treated patients. Eight patients relapsed, 7 of whom subsequently died. The median time to relapse among these 8 patients was 54 days (range, 26 to 1364 days). No cases of nonrelapse mortality were observed in the first year after transplantation. However, 2 patients died in remission from complications of chronic GVHD and cardiomyopathy, at 18 months and 14 months after transplantation, respectively. This study suggests that patients may tolerate myeloablative doses >28 Gy delivered to the liver using (131)I-anti-CD45 antibody in addition to standard reduced-intensity conditioning. Moreover, the arbitrary limit of 43 Gy to the marrow may be unnecessarily conservative, and continued escalation of targeted radioimmunotherapy doses may be feasible to further reduce relapse.

  11. Are antibiotics a safe and effective treatment for acute uncomplicated appendicitis?

    Acute appendicitis is a common cause of acute abdominal pain and the most frequent cause of emergency abdominal surgery. In the last two decades, growing evidence has been published about the use of antibiotics as the exclusive treatment for acute appendicitis. Searching in Epistemonikos database, which is maintained by screening 30 databases, we identified only one systematic review including one pertinent randomized trial. We generated a summary of findings following the GRADE approach. We concluded the use of antibiotics to treat acute uncomplicated appendicitis may be less effective than appendectomy and probably increases major complications compared with appendectomy.

  12. Acute pancreatitis with saw palmetto use: a case report

    PubMed Central

    2011-01-01

    Introduction Saw palmetto is a phytotherapeutic agent commercially marketed for the treatment of benign prostatic hyperplasia. Evidence suggests that saw palmetto is a safe product, and mild gastrointestinal adverse effects have been reported with its use. We report a case of acute pancreatitis, possibly secondary to the use of saw palmetto. Case presentation A 61-year-old Caucasian man with a history of benign prostatic hyperplasia and gastroesophageal reflux disease developed epigastric pain associated with nausea 36 hours prior to presentation. He denied drinking alcohol prior to the development of his symptoms. His home medications included saw palmetto, lansoprazole and multivitamins. Laboratory results revealed elevated lipase and amylase levels. An abdominal ultrasound demonstrated a nondilated common bile duct, without choledocholithiasis. Computed tomography of his abdomen showed the pancreatic tail with peripancreatic inflammatory changes, consistent with acute pancreatitis. Our patient's condition improved with intravenous fluids and pain management. On the fourth day of hospitalization his pancreatic enzymes were within normal limits: he was discharged home and advised to avoid taking saw palmetto. Conclusion It is our opinion that a relationship between saw palmetto and the onset of acute pancreatitis is plausible, and prescribers and users of saw palmetto should be alert to the possibility of such adverse reactions.

    Mechanical assist devices are indicated for hemodynamic stabilization in acute circulatory arrest if conventional means of cardiopulmonary resuscitation are unable to re-establish adequate organ perfusion. Their temporary use facilitates further diagnostic and therapeutic options in selected patients, e.g. coronary angiography followed by revascularization.External thorax compression devices allow sufficient cardiac massage in case of preclinical or in-hospital circulatory arrest, especially under complex transfer conditions. These devices perform standardized thorax compressions at a rate of 80-100 per minute. Invasive mechanical support devices are used in the catheter laboratory or in the intensive care unit. Axial turbine pumps, e.g. the Impella, continuously pump blood from the left ventricle into the aortic root. The Impella can also provide right ventricle support by pumping blood from the vena cava into the pulmonary artery. So-called emergency systems or ECMO devices consist of a centrifugal pump and a membrane oxygenator allowing complete takeover of cardiac and pulmonary functions. Withdrawing blood from the right atrium and vena cava, oxygenated blood is returned to the abdominal aorta. Isolated centrifugal pumps provide left heart support without an oxygenator after transseptal insertion of a venous cannula into the left atrium.Mechanical assist devices are indicated for acute organ protection and hemodynamic stabilization for diagnostic and therapeutic measures as well as bridge to myocardial recovery. Future technical developments and better insights into the pathophysiology of mechanical circulatory support will broaden the spectrum of indications of such devices in acute circulatory arrest.

    The acute replacement of full-thickness abdominal wall has been facilitated by polypropylene mesh (Marlex) (PPM), allowing debridement of nonviable tissue and restoration of abdominal wall integrity without tension. However, no substantial long-term follow-up has been reported on the definitive wound coverage after the use of PPM in open wounds. Since 1976, we have placed PPM in 31 patients; 25 for infectious complication, three for massive bowel distension preventing abdominal closure, and three for shotgun wounds with extensive tissue loss. In 29 of 31 patients, the mesh was placed in heavily contaminated wounds; extensive fasciitis was present in 23 patients and 21 had intra-abdominal abscesses. Following mesh placement, 23 reoperations were required for continuing complications. No patients eviscerated, despite these multiple procedures. Polypropylene mesh was highly effective in restoring abdominal wall continuity. Despite advantages when PPM was used, significant long-term problems developed. Seven patients died from their primary illness in the postoperative period. Nine wounds were closed by granulation and subsequent split-thickness skin grafts. All nine developed mesh extrusion and/or enteric fistulae. Nine wounds healed by secondary intention, six developed enteric fistulae or continuing mesh extrusion. Full-thickness flap coverage after granulation provided the best means of wound closure. Polypropylene mesh had significant early advantages for providing abdominal wall integrity even in the presence of severe infection. However, long-term problems were common when wounds were closed to skin grafts or secondary intention. If the mesh cannot be completely removed, strong consideration should be given to myocutaneous flaps for coverage after the primary illness has resolved. Images Fig. 1. Fig. 2. Fig. 3. PMID:6455099

  15. Acute otitis media and acute bacterial sinusitis.

    PubMed

    Acute otitis media and acute bacterial sinusitis are 2 of the most common indications for antimicrobial agents in children. Together, they are responsible for billions of dollars of health care expenditures. The pathogenesis of the 2 conditions is identical. In the majority of children with each condition, a preceding viral upper respiratory tract infection predisposes to the development of the acute bacterial complication. It has been shown that viral upper respiratory tract infection predisposes to the development of acute otitis media in 37% of cases. Currently, precise microbiologic diagnosis of acute otitis media and acute bacterial sinusitis requires performance of tympanocentesis in the former and sinus aspiration in the latter. The identification of a virus from the nasopharynx in either case does not obviate the need for antimicrobial therapy. Furthermore, nasal and nasopharyngeal swabs are not useful in predicting the results of culture of the middle ear or paranasal sinus. However, it is possible that a combination of information regarding nasopharyngeal colonization with bacteria and infection with specific viruses may inform treatment decisions in the future.

    Open abdomen (OA) has been an effective treatment for abdominal catastrophes in traumatic and general surgery. However, management of patients with OA remains a formidable task for surgeons. The central goal of OA is closure of fascial defect as early as is clinically feasible without precipitating abdominal compartment syndrome. Historically, techniques such as packing, mesh, and vacuum-assisted closure have been developed to assist temporary abdominal closure, and techniques such as components separation, mesh-mediated traction, bridging fascial defect with permanent synthetic mesh, or biologic mesh have also been attempted to achieve early primary fascial closure, either alone or in combined use. The objective of this review is to present the challenges of these techniques for OA with a goal of early primary fascial closure, when the patient's physiological condition allows. PMID:26819597

    Cystic fibrosis (CF) is a multisystem disease with a range of abdominal manifestations including those involving the liver, pancreas, and kidneys. Recent advances in management of the respiratory complications of the disease has led to a greater life expectancy in patients with CF. Subsequently, there is increasing focus on the impact of abdominal disease on quality of life and survival. Liver cirrhosis is the most important extrapulmonary cause of death in CF, yet significant challenges remain in the diagnosis of CF related liver disease. The capacity to predict those patients at risk of developing cirrhosis remains a significant challenge. We review representative abdominal imaging findings in patients with CF selected from the records of two academic health centres, with a view to increasing familiarity with the abdominal manifestations of the disease. We review their presentation and expected imaging findings, with a focus on the challenges facing diagnosis of the hepatic manifestations of the disease. An increased familiarity with these abdominal manifestations will facilitate timely diagnosis and management, which is paramount to further improving outcomes for patients with cystic fibrosis.

    The Rome diagnostic criteria for the functional bowel disorders and functional abdominal pain are used widely in research and practice. A committee consensus approach, including criticism from multinational expert reviewers, was used to revise the diagnostic criteria and update diagnosis and treatment recommendations, based on research results. The terminology was clarified and the diagnostic criteria and management recommendations were revised. A functional bowel disorder (FBD) is diagnosed by characteristic symptoms for at least 12 weeks during the preceding 12 months in the absence of a structural or biochemical explanation. The irritable bowel syndrome, functional abdominal bloating, functional constipation, and functional diarrhea are distinguished by symptom-based diagnostic criteria. Unspecified FBD lacks criteria for the other FBDs. Diagnostic testing is individualized, depending on patient age, primary symptom characteristics, and other clinical and laboratory features. Functional abdominal pain (FAP) is defined as either the FAP syndrome, which requires at least six months of pain with poor relation to gut function and loss of daily activities, or unspecified FAP, which lacks criteria for the FAP syndrome. An organic cause for the pain must be excluded, but aspects of the patient's pain behavior are of primary importance. Treatment of the FBDs relies upon confident diagnosis, explanation, and reassurance. Diet alteration, drug treatment, and psychotherapy may be beneficial, depending on the symptoms and psychological features.

    Abdominal adhesions consist of fibrotic tissue that forms in the peritoneal space in response to an inflammatory insult, typically surgery or intraabdominal infection. The precise mechanisms underlying adhesion formation are poorly understood. Many compounds and physical barriers have been tested for their ability to prevent adhesions after surgery with varying levels of success. The mouse and rat are important models for the study of abdominal adhesions. Several different techniques for the creation of adhesions in the mouse and rat exist in the literature. Here we describe a protocol utilizing abrasion of the cecum with sandpaper and sutures placed in the right abdominal sidewall. The mouse is anesthetized and the abdomen is prepped. A midline laparotomy is created and the cecum is identified. Sandpaper is used to gently abrade the surface of the cecum. Next, several figure-of-eight sutures are placed into the peritoneum of the right abdominal sidewall. The abdominal cavity is irrigated, a small amount of starch is applied, and the incision is closed. We have found that this technique produces the most consistent adhesions with the lowest mortality rate.

    Sarcoidosis is a multisystem inflammatory disease of unknown etiology. The lungs and the lymphoid system are the most commonly involved organs. Extrapulmonary involvement is reported in 30% of patients, and the abdomen is the most common extrapulmonary site with a frequency of 50%–70%. Although intra-abdominal sarcoidosis is usually asymptomatic, its presence may affect the prognosis and treatment options. The lesions are less characteristic and may mimick neoplastic or infectious diseases such as lymphoma, diffuse metastasis, and granulomatous inflammation. The liver and spleen are the most common abdominal sites of involvement. Sarcoidosis of the gastrointestinal system, pancreas, and kidneys are extremely rare. Adenopathy which is most commonly found in the porta hepatis, exudative ascites, and multiple granulomatous nodules studding the peritoneum are the reported manifestations of abdominal sarcoidosis. Since abdominal sarcoidosis is less common and long-standing, unrecognized disease can result in significant morbidity and mortality. Imaging contributes to diagnosis and management of intra-abdominal sarcoidosis. In this report we reviewed the cross-sectional imaging findings of hepatobiliary, gastrointestinal, and genitourinary sarcoidosis. PMID:25512071
