    2015-11-01

    Acute disorders of the abdominal aorta are potentially lethal conditions that require prompt evaluation and treatment. Computed tomography (CT) is the primary imaging method for evaluating these conditions because of its availability and speed. Volumetric CT acquisition with multiplanar reconstruction and three-dimensional analysis is now the standard technique for evaluating the aorta. MR imaging may be useful for select applications in stable patients in whom rupture has been excluded. Imaging is indispensable for diagnosis and treatment planning, because management has shifted toward endoluminal repair. Acute abdominal aortic conditions most commonly are complications of aneurysms and atherosclerosis. PMID:26526434

  2. Acute incarcerated external abdominal hernia

    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

  3. Acute Abdominal Pain in Children.

    Acute abdominal pain accounts for approximately 9% of childhood primary care office visits. Symptoms and signs that increase the likelihood of a surgical cause for pain include fever, bilious vomiting, bloody diarrhea, absent bowel sounds, voluntary guarding, rigidity, and rebound tenderness. The age of the child can help focus the differential diagnosis. In infants and toddlers, clinicians should consider congenital anomalies and other causes, including malrotation, hernias, Meckel diverticulum, or intussusception. In school-aged children, constipation and infectious causes of pain, such as gastroenteritis, colitis, respiratory infections, and urinary tract infections, are more common. In female adolescents, clinicians should consider pelvic inflammatory disease, pregnancy, ruptured ovarian cysts, or ovarian torsion. Initial laboratory tests include complete blood count, erythrocyte sedimentation rate or C-reactive protein, urinalysis, and a pregnancy test. Abdominal radiography can be used to diagnose constipation or obstruction. Ultrasonography is the initial choice in children for the diagnosis of cholecystitis, pancreatitis, ovarian cyst, ovarian or testicular torsion, pelvic inflammatory disease, pregnancy-related pathology, and appendicitis. Appendicitis is the most common cause of acute abdominal pain requiring surgery, with a peak incidence during adolescence. When the appendix is not clearly visible on ultrasonography, computed tomography or magnetic resonance imaging can be used to confirm the diagnosis. PMID:27175718

  4. CT of acute abdominal aortic disorders.

    2003-11-01

    Aortic aneurysm rupture, aortic dissection, PAU, acute aortic occlusion, traumatic aortic injury, and aortic fistula represent acute abdominal aortic conditions. Because of its speed and proximity to the emergency department, helical CT is the imaging test of choice for these conditions. MR imaging also plays an important role in the imaging of aortic dissection and PAU, particularly when the patient is unable to receive intravenous contrast material. In this era of MDCT, conventional angiography is used as a secondary diagnostic tool to clarify equivocal findings on cross-sectional imaging. Ultrasound is helpful when CT is not readily available and the patient is unable or too unstable to undergo MR imaging. PMID:14661663

  5. Abdominal migraine in the differential diagnosis of acute abdominal pain.

    PubMed

    2015-06-01

    Although traditionally regarded as a specific pediatric disease, abdominal migraine may also be observed in adults. Unfortunately, however, this condition is frequently overlooked in the differential diagnosis of abdominal pain in the emergency department (ED). A 30-year-old woman presented to our ED complaining of abdominal pain and vomiting, lasting for 12 hours. The pain was periumbilical, continuous, and not associated with fever or diarrhea. The physical examination and the results of conventional blood tests were normal. The patient was treated with intravenous ketoprofen, metoclopramide, and ranitidine, obtaining a prompt relief of symptoms. She had a history of similar episodes in the last 15 years, with several ED visits, blood test examinations, ultrasonography of the abdomen, and upper gastrointestinal endoscopies. Celiac disease, porphyry, sickle cell disease, and inflammatory bowel disease were all excluded. In July 2012, she became pregnant, and she delivered a healthy baby on April 2013. Until November 2014, she has remained asymptomatic. Based on the clinical characteristics of the abdominal pain episodes, the exclusion of any alternative diagnosis, and the relief of symptoms during and after pregnancy, a final diagnosis of abdominal migraine could be established. A skilled emergency physician should always consider abdominal migraine in the differential diagnosis of patients admitted to the ED with abdominal pain, especially when the attacks are recurrent and no alternative diagnosis can be clearly established.

    2014-01-01

    Hip surgeries are some of the most common and successful orthopedic procedures. Although rarely, abdominal complications do occur and are associated with unfavorable outcomes.We aimed to identify and describe the severe abdominal complications that appear in patients under-going elective or traumatic hip surgery. A four year retrospective electronic database research identified 408 elective primary hip replacements,51 hip revisions and 1040 intra and extracapsular proximal femur fractures. Out of these, three males and 4 females between 64 - 84 years old were identified to have developed acute abdominal complications: perforated acute ulcer (3),acute cholecystitis (2), volvulus (1), toxic megacolon with peritonitis (1) and acute colonic pseudo-obstruction (1).Complications debuted 3 - 10 days after index orthopedic surgery. Acute perioperative abdominal complications are rarely encountered during orthopedic surgery. When these do occur, they do so almost exclusively in patients with hippathology, comorbidities and most often lead to life threatening situations. We thus emphasize the need for early identification and appropriate management by both orthopedic and general surgery doctors in order to improve patient safety. PMID:24742414

    Introduction Mondor disease (MD), a superficial thrombophlebitis of the thoraco-epigastric veins and their confluents is rarely reported in the literature. The superior epigastric vein is the most affected vessel but involvement of the inferior epigastric vessels or their branches have also been described. There is no universal consensus on treatment in the literature but most authors suggest symptomatic treatment with non-steroid anti-inflammatory drugs (NSAIDs). Case report We report the case of a marathon runner who presented with right iliac fossa pain mimicking the clinical symptomatology of an acute appendicitis. The history and the calculated Alvarado score were not in favor of an acute appendicitis. This situation motivated multiple investigations and we finally arrived at the diagnosis of MD. Discussion Acute appendicitis (AA) is the most common cause of surgical emergencies and one of the most frequent indications for an urgent abdominal surgical procedure around the world. In some cases, right lower quadrant pain remains unclear in spite of US, CT scan, and exclusion of urological and gynecological causes, thus we need to think of some rare pathologies like MD. Conclusion MD is often mentioned in the differential diagnosis of breast pathologies but rarely in abdominal pain assessment. It should be mentioned in the differential diagnosis of the right lower quadrant pain when the clinical presentation is unclear and when acute appendicitis has been excluded. Awareness of MD can avoid misdiagnosis and decrease extra costs by sparing unnecessary imaging. PMID:26803533

  8. Intra-abdominal hypertension and acute pancreatitis.

    Intra-abdominal hypertension (IAH) contributes to organ dysfunction and leads to the development of the abdominal compartment syndrome (ACS). IAH and ACS are relatively frequent findings in patiens with severe acute pancreatitis (SAP) and are associated with deterioration in organ functions. The most affected are cardiovascular, respiratory and renal functions. The incidence of IAH in patients with SAP is approximately 60-80%. There is an accumulating evidence in human and animal studies that changes of perfusion, particularly to the microvasculature, are crucial events in the progression of acute pancreatitis (AP). The perfusion of the small and large intestine is impaired due to reduced arterial pressure, increased vascular resistence and diminished portal blood flow. Bacterial translocation has been described in patients with ACS, and this may apply to patients with SAP. Approximately 30-40% of SAP patients develop ACS because of pancreatic (retroperitoneal) inflammation, peripancreatic tissue edema, formation of fluid collections or abdominal distension. Surgical debridement was the preferred treatment to control necrotizing pancreatitis in the past. However, the management of necrotizing pancreatitis has changed over the last decade. The main objective of this article is to describe the association between IAH and AP and to emphasize this situation in clinical praxis as well (Fig. 1, Ref. 38). PMID:23406186

  9. Diagnosis of acute abdominal pain in older patients.

    PubMed

    Lyon, Corey; Clark, Dwayne C

    2006-11-01

    Acute abdominal pain is a common presenting complaint in older patients. Presentation may differ from that of the younger patient and is often complicated by coexistent disease, delays in presentation, and physical and social barriers. The physical examination can be misleadingly benign, even with catastrophic conditions such as abdominal aortic aneurysm rupture and mesenteric ischemia. Changes that occur in the biliary system because of aging make older patients vulnerable to acute cholecystitis, the most common indication for surgery in this population. In older patients with appendicitis, the initial diagnosis is correct only one half of the time, and there are increased rates of perforation and mortality when compared with younger patients. Medication use, gallstones, and alcohol use increase the risk of pancreatitis, and advanced age is an indicator of poor prognosis for this disease. Diverticulitis is a common cause of abdominal pain in the older patient; in appropriately selected patients, it may be treated on an outpatient basis with oral antibiotics. Small and large bowel obstructions, usually caused by adhesive disease or malignancy, are more common in the aged and often require surgery. Morbidity and mortality among older patients presenting with acute abdominal pain are high, and these patients often require hospitalization with prompt surgical consultation. PMID:17111893

    Acute abdominal aortic thrombosis is a rare and potential fatal event, which occurs in adult subjects. We present the case of a 72-year-old-man, who referred to the emergency Department of our hospital because of persistent severe abdominal and perineal pain. Doppler ultrasounds and computerized tomography angiography revealed the acute thrombosis of the abdominal aorta. Immediate revascularization through aortic thrombo-endoarterectomy resolved the disease. PMID:23830410

    Acute abdominal pain in pregnancy presents diagnostic and therapeutic challenges. Standard imaging techniques need to be adapted to reduce harm to the fetus from X-rays due to their teratogenic and carcinogenic potential. Ultrasound remains the primary imaging investigation of the pregnant abdomen. Magnetic resonance imaging (MRI) has been shown to be useful in the diagnosis of gynaecological and obstetric problems during pregnancy and in the setting of acute abdomen during pregnancy. MRI overcomes some of the limitations of ultrasound, mainly the size of the gravid uterus. MRI poses theoretical risks to the fetus and care must be taken to minimise these with the avoidance of contrast agents. This article reviews the evolving imaging and clinical literature on appropriate investigation of acute abdominal and pelvic pain during established intrauterine pregnancy, addressing its common causes. Guidelines based on the current literature and on the accumulated clinico-radiological experience of the European Society of Urogenital Radiology (ESUR) working group are proposed for imaging these suspected conditions.

    2008-01-01

    Colorectal carcinoma (KCR) is the commonest malignancy in male patients and the second commonest in female patients in the Czech Republic. During 1990-2006, 1162 patients with colorectal carcinomas were operated in the FTNsP (Faculty Thomayer Hospital) Surgical Clinic. 212 patients aged between 39 to 94 y.o.a.(the median of 70 y.o.a) were managed urgently for acute abdominal illness. In this group of urgently managed patients, the mortality rate was 17% and the morbidity rate was 38%. Future prospects of any colorectal carcinoma patient with acute abdominal illness depend on the procedure's radicality, which is limited by the overall patient's condition. The preoperative care aims to improve the patient's overall condition to such a degree, to allow for surgery fulfilling principles of oncosurgical radicality. According to this report's data, such urgent surgical procedures do not result in increased mortality or morbidity rates, compared to these in planned procedures, and show the best results in this patient group.

    2013-01-01

    Chilaiditi syndrome is a rare condition occurring in 0.025% to 0.28% of the population. In these patients, the colon is displaced and caught between the liver and the right hemidiaphragm. Patients' symptoms can range from asymptomatic to acute intermittent bowel obstruction. Diagnosis is best achieved with CT imaging. Identification of Chilaiditi syndrome is clinically significant as it can lead to many significant complications such as volvulus, perforation, and bowel obstruction. If the patient is symptomatic, treatment is usually conservative. Surgery is rarely indicated with indications including ischemia and failure of resolution with conservative management.

    In the pediatric patient, computed tomography (CT) scan as an imaging modality for evaluation of the abdomen is to be used judiciously. The use of correct scanning protocols, single phase scanning, scanning only when required are key factors to minimize radiation doses to the child, while providing diagnostic quality. CT is the preferred modality in the evaluation of trauma, to assess extent of solid organ or bowel injury. It is also useful in several inflammatory conditions such as inflammatory bowel diseases and acute pancreatitis. CT also has an important role in evaluating intra-abdominal tumors, although magnetic resonance imaging (MRI) can be used as an alternative to CT. PMID:26964550

    Evaluation of the emergency department patient with acute abdominal pain is sometimes difficult. Various factors can obscure the presentation, delaying or preventing the correct diagnosis, with subsequent adverse patient outcomes. Clinicians must consider multiple diagnoses, especially those life-threatening conditions that require timely intervention to limit morbidity and mortality. This article will review general information on abdominal pain and discuss the clinical approach by review of the history and the physical examination. Additionally, this article will discuss the approach to unstable patients with abdominal pain. PMID:23055768

    This study explores the feasibility of a decision-support system for patients seeking care for acute abdominal pain, and, specifically the diagnosis of acute diverticulitis. We used a linear support vector machine (SVM) to separate diverticulitis from all other reported cases of abdominal pain and from the important differential diagnosis non-specific abdominal pain (NSAP). On a database containing 3337 patients, the SVM obtained results comparable to those of the doctors in separating diverticulitis or NSAP from the remaining diseases. The distinction between diverticulitis and NSAP was, however, substantially improved by the SVM. For this patient group, the doctors achieved a sensitivity of 0.714 and a specificity of 0.963. When adjusted to the physicians' results, the SVM sensitivity/specificity was higher at 0.714/0.985 and 0.786/0.963 respectively. Age was found as the most important discriminative variable, closely followed by C-reactive protein level and lower left side pain.

    Evaluation of acute abdominal and pelvic pain in pregnancy presents a diagnostic challenge for clinicians and radiologists alike. The differential diagnosis includes obstetric and nonobstetric conditions unique to pregnancy, in addition to causes of acute abdominal and pelvic pain unrelated to the pregnancy. The clinical presentation and course of disease may be altered in pregnancy, and several pathologies are exacerbated by pregnancy. Discriminating clinical features in the diagnosis of abdominal and pelvic pain are often confounded by expected anatomic and physiologic changes in pregnancy. Moreover, while diagnostic pathways may be altered in pregnancy, the necessity for a timely and accurate diagnosis must be underscored, as delay in treatment may result in an undesirable increase in morbidity and/or mortality for both the patient and fetus. Advances in magnetic resonance imaging (MRI) through faster acquisition and motion-insensitive techniques, coupled with increased awareness and education regarding the value of MRI in diagnosing a wide range of pathology, have established MRI as a valuable strategy in the investigation of acute abdominal and pelvic pain in the pregnant patient. This review presents a practical approach to common obstetric and nonobstetric causes of acute abdominal and pelvic pain during pregnancy, as well as safety considerations for performing MRI in this patient population.

    1975-06-01

    A study was performed to determine the value of peritoneal lavage in the acute abdomen not related to trauma. Lavage was performed in 33 patients in the evaluation of abdominal pain of sufficient degree to warrant consideration for surgical intervention. Peritoneal lavage was truly positive or truly negative in 64% of the cases. It showed false negative results in 28% and false positive results in 8%. The lavage was most accurate in the evaluation of appendicitis, colonic disease, and intra abdominal bleeding. It was highly inaccurate in the evaluation of cholecystitis and peptic ulcer disease. It was concluded that the peritoneal lavage can be a useful adjunct in the evaluation of patients with abdominal pain and should be considered in difficult diagnostic problems but not routinely employed.

    Background: To highlight the problems of diagnosis and management of acute abdomen in patients with lassa fever. And to also highlight the need for high index of suspicion of lassa fever in patients presenting with acute abdominal pain in order to avoid surgical intervention with unfavourable prognosis and nosocomial transmission of infections, especially in Lassa fever-endemic regions. Materials and Methods: A review of experiences of the authors in the management of lassa fever over a 4-year period (2004-2008). Literature on lassa fever, available in the internet and other local sources, was studied in November 2010 and reviewed. Results: Normal plain chest radiographic picture can change rapidly due to pulmonary oedema, pulmonary haemorrhage and acute respiratory distress syndrome. Plain abdominal radiograph may show dilated bowels with signs of paralytic ileus or dynamic intestinal obstruction due to bowel wall haemorrhage or inflamed and enlarged Peyer's patches. Ultrasound may show free intra-peritoneal fluid due to peritonitis and intra-peritoneal haemorrhage. Bleeding into the gall bladder wall may erroneously suggest infective cholecystitis. Pericardial effusion with or without pericarditis causing abdominal pain may be seen using echocardiography. High index of suspicion, antibody testing for lassa fever and viral isolation in a reference laboratory are critical for accurate diagnosis. Conclusion: Patients from lassa fever-endemic regions may present with features that suggest acute abdomen. Radiological studies may show findings that suggest acute abdomen but these should be interpreted in the light of the general clinical condition of the patient. It is necessary to know that acute abdominal pain and vomiting in lassa fever-endemic areas could be caused by lassa fever, which is a medical condition. Surgical option should be undertaken with restraint as it increases the morbidity, may worsen the prognosis and increase the risk of nosocomial transmission

    Acute cerebrovascular disorders were found in 4.78% of the patients operated on for acute abdominal diseases. Such disorders were revealed during the first 3 days of the postoperative period in 86.9% and appeared as transitory ischemic attacks (21.9%), acute hypertensive encephalopathy (12.4%), ischemic stroke with reversible neurological deficit (27.6%), ischemic stroke with stable neurological deficit (20%), hemorrhagic stroke (2.9%), mixed stroke (2.9%). The pathogenesis of vascular disorder in examined cases included systemic and cerebral hemodynamic disorders, acid-alkaline imbalance, impaired blood gas composition and biochemical and physicochemical blood properties, altered cranial great arteries, cerebrovascular emboli, endogenous intoxication and age-related changes. In the first 24 postoperative hours, actovegin and instenon therapy accelerated neurological deficit regression and recovered cerebral hemodynamics in postoperative strokes. PMID:10957794

    To assess prospectively the usefulness of hepatobiliary imaging in acute abdominal pain (72 hr or less), 36 patients were scintigraphed. Before the procedure, the referring physician completed Part I of a questionnaire indicating his differential diagnosis, diagnostic confidence (expressed as a percentage), and therapeutic plan. Immediately after the test, the same physician with knowledge of the results, completed Part II of the questionnaire indicating again his differential diagnosis, diagnostic confidence, and therapeutic plan. The impact of the imaging on the physician's diagnostic confidence was expressed as a log-likelihood-ratio (LLR).

    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.

    Whether intestinal toxicity of preferential or selective COX-2 inhibitors is reduced compared with that of standard NSAIDs is controversial. A 26-year-old woman presented with acute abdominal pain and bloody diarrhoea a few days after beginning meloxicam treatment. Endoscopic examination of the colon showed erythematous and ulcerative lesions involving 15 cm of the left colon. No aetiology has been found for colitis. Diarrhea disappeared 1 week after meloxicam was stopped. Total colonoscopy 3 months and 2 years later was normal. The role of meloxicam in the etiology of colitis was considered plausible. This report and a few other cases in the literature suggest that cyclooxygenase-2 selective non-steroidal anti-inflammatory drug inhibitor toxicity should be investigated in case of unexplained acute colitis.

    Herlyn-Werner-Wunderlich (HWW) syndrome is a rare müllerian duct anomaly with uterus didelphys, unilateral obstructed hemivagina, and ipsilateral renal agenesis. Patients with this syndrome generally present after menarche with pelvic pain and mass and, rarely, primary infertility in later years. Strong suspicion and knowledge of this syndrome are mandatory for an accurate diagnosis. A 14-year-old female patient presented with acute retention of urine and abdominopelvic pain. Her condition was diagnosed with the use ultrasonography and magnetic resonance imaging as a case of HWW syndrome. She was treated with vaginal hemiseptal resection. The HWW syndrome should be considered among the differential diagnoses in girls with renal anomalies presenting with pelvic mass, symptoms of acute abdominal pain, and acute urinary retention.

    Acute abdominal pain represents the cardinal symptom behind a vast number of possible under-lying causes including several ones that re-quire surgical treatment. It is the most common sur-gical emergency, the most common cause for a surgical consultation in the emergency department and the most common cause for non-trauma related hospital admissions. The golden mis-sion statement is to rapidly identify whether the underlying cause requires an urgent or even immediate surgical intervention. However, behind the same cardinal symptom one may encounter harmless or non-urgent problems. By employing diagnostic means cost effectively and with the aim to avoid unnecessary exposure of the patient to X-rays in mind, the challenge remains to identify patients with an indication for emergency surgery from those who suffer from a less serious condition and thus can be treated conservatively and without any pressure of time. Dealing with such a highly complex decision-making process calls for a clinical algorithm. Many publications are available that have scrutinised the different aspects of the initial assessment and the emergency management of acute abdominal pain. How-ever, the large body of evidence seems to miss articles that describe a formally correct priority- and problem-based approach. Clinical algorithms apply to complex disease states such as acute abdominal pain and translate them into one clearly laid out, logically coordinated and systematic overall process. Our intention is to devel-op such an algorithm to approach acute abdominal pain from the surgeon's point of view. Based on daily practice and with reference to available literature, it is the aim of this study to define a work flow that simply summarises all steps in-volved and defines the required decision process in order to form the intellectual basis for an evidence-based clinical algorithm. The result is illustrated as a first draft of such an evidence-based algorithm to allow emergency evaluation of

    Varicella zoster is an acute viral infection that results from reactivation of a latent varicella zoster virus. It usually occurs in adult population and immune compromised patients. It rarely occurs in healthy children. Here we present a 14 years old male with varicella zoster that had abdominal pain mimicking acute abdomen to alert others who are consulted for the differentiation of acute abdomen and others who may be consulted for pain management.

    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.

    Multidetector CT (MDCT) is an imaging technique that provides otherwise unobtainable information in the diagnostic work-up of patients presenting with acute abdominal pain. A correct working diagnosis depends essentially on understanding the individual patient's clinical data and laboratory findings. In haemodynamically stable patients with acute severe and generalized abdominal pain, MDCT is now the preferred imaging test and gives invaluable diagnostic information, also in unstable patients after stabilization. In this descriptive review, we focus our attention on acute, severe and generalized or undifferentiated non-traumatic abdominal pain. The main differential diagnoses are acute pancreatitis, gastrointestinal perforation, ruptured abdominal aneurysm and acute mesenteric ischaemia. We will provide radiologist readers with a technical guide to optimize MDCT imaging protocols and list the major CT signs essential to reach a correct diagnosis and guide the best treatment.

    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.

    2010-01-01

    INTRODUCTION Acute appendicitis commonly presents as an acute abdomen. Cases of acute appendicitis caused by blunt abdominal trauma are rare. We present a systematic review of appendicitis following blunt abdominal trauma. The aim of this review was to collate and report the clinical presentations and experience of such cases. SUBJECTS AND METHODS A literature review was performed using PubMed, Embase and Medline and the keywords ‘appendicitis’, ‘abdominal’ and ‘trauma’. RESULTS The initial search returned 381 papers, of which 17 articles were included. We found 28 cases of acute appendicitis secondary to blunt abdominal trauma reported in the literature between 1991 and 2009. Mechanisms of injury included road-traffic accidents, falls, assaults and accidents. Presenting symptoms invariably included abdominal pain, but also nausea, vomiting and anorexia. Only 12 patients had computed tomography scans and 10 patients had ultrasonography. All reported treatment was surgical and positive for appendicitis. CONCLUSIONS Although rare, the diagnosis of acute appendicitis must be considered following direct abdominal trauma especially if the patient complains of abdominal right lower quadrant pain, nausea and anorexia. Haemodynamically stable patients who present shortly after blunt abdominal trauma with right lower quadrant pain and tenderness should undergo urgent imaging with a plan to proceed to appendicectomy if the imaging suggested an inflammatory process within the right iliac fossa.

    Abdominal compartment syndrome (ACS) in patients with severe acute pancreatitis (SAP) is a marker of severe disease. It occurs as combination of inflammation of retroperitoneum, visceral edema, ascites, acute peripancreatic fluid collections, paralytic ileus, and aggressive fluid resuscitation. The frequency of ACS in SAP may be rising due to more aggressive fluid resuscitation, a trend towards conservative treatment, and attempts to use a minimally invasive approach. There remains uncertainty about the most appropriate surgical technique for the treatment of ACS in SAP. Some unresolved questions remain including medical treatment, indications, timing, and interventional techniques. This review will focus on interventional treatment of this serious condition. First line therapy is conservative treatment aiming to decrease IAP and to restore organ dysfunction. If nonoperative measures are not effective, early abdominal decompression is mandatory. Midline laparostomy seems to be method of choice. Since it carries significant morbidity we need randomized studies to establish firm advantages over other described techniques. After ACS resolves efforts should be made to achieve early primary fascia closure. Additional data are necessary to resolve uncertainties regarding ideal timing and indication for operative treatment. PMID:26839539

    Acute intermittent porphyria (AIP) is an inherited deficiency in the haem biosynthesis pathway. AIP is rare, affecting around 1 in 75 000 people. Acute attacks are characterised by abdominal pain associated with autonomic, neurological and psychiatric symptoms. AIP is rarely associated with posterior reversible encephalopathy syndrome (PRES). PRES is a clinicoradiological condition caused by the failure of the posterior circulation to autoregulate, resulting in cerebral oedema, headaches, nausea and seizures. This association is important because drugs used in the management of seizures may worsen an attack of AIP. This article describes a case of AIP and PRES in a young woman. PMID:27277587

    Abdominal pain in elderly patients leads to challenge due to diagnostic difficulty and high incidence of complications. This case report presents an elderly patient with acute and severe abdominal pain, who did not respond to Western treatments. The patient was diagnosed to have abdominal pain by Yang deficiency of spleen (脾陽虛). Acupuncture (mainly at LI4 and LR3), indirect moxibustion (CV4 and CV8), and a herbal drug [DaehwangBuja-Tang (大黃附子湯)] were given to the patient; the abdominal pain and related symptoms disappeared completely within 3 days. This study proved the potential use of traditional Korean medicine for treating abdominal pain in elderly patients. PMID:25441951

    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.

    The presence of a tumour, poor general condition, features of anaemia, increased erythrocyte sedimentation rates and imaging suggesting malignancy were the common features in 4 different tumour-like abdominal conditions that are extremely rare in childhood. These conditions included: extensive retroperitoneal tumour with rib involvement that turned out to be an inflammatory lesion caused by Actinomyces in a 12-year-old girl; multi-loculated tumour of the mesentery/ovary caused by mesenteric lymphadenopathy in the course of a Salmonella enteritidis infection in a 2.5-year-old girl; tumour of the VII - VIII hepatic segments that turned out to be the focus of granuloma in the course of lambliasis in a 5.5-year-old boy with a history of purulent neck lymphadenopathy and a final suspicion of immunocompromise; and a multi-loculated tumour of the small pelvis and inguinal area that turned out to be an abscess of the iliopsoas muscle in a 16-year-old boy. Apart from the imaging, the lesions required cytological examination of the material harvested by fine-needle biopsies (liver tumour) or histopathological investigations (retroperitoneal tumour, mesenteric/ovarian tumour, liver tumour and--on second surgery--the pelvic tumour) and/or bacteriological examination (all cases), serological examination (liver tumour and mesenteric/ovarian tumour), protozoal investigation (liver tumour), and measurement of AFP levels (mesenteric/ovarian tumour). Surgical treatment (retroperitoneal tumour, mesenteric/ovarian tumour and tumour of the small pelvis) and guided antibiotic therapy (all cases including 15 weeks of antibiotics in the first case) allowed complete recovery in 3 patients (actinomycosis, mesenteric lymphadenopathy, abscess of the iliopsoas muscle). Antibiotic and antiprotozoal therapy cured the granulomatous hepatitis; however this patient tended to develop severe right-sided pleural/pulmonary changes (the child was referred for further diagnosis with suspicion of

    Hysterectomy is the most common major gynecologic procedure. Although alternatives to hysterectomy result in fewer procedures performed annually, and the use of endoscopic techniques and vaginal hysterectomy have resulted in a lower percentage performed by the open abdominal route, certain pelvic disorders require abdominal hysterectomy. Preoperative evaluation with informed consent and surgical planning are essential to select appropriate candidates. Prophylactic antibiotics, thromboprophylaxis, attention to surgical technique, and enhanced recovery protocols should be used to provide optimal outcomes. PMID:27521877

    Background: Abdominal pain is one of the most common reasons for presenting to the emergency depatment (ED) and the etiology is varied. Materials and Methods: This prospective observational study was conducted in a large ED of a tertiary care center in India. All patients older than 15 years and presenting with non-traumatic abdominal pain to the ED from May 2012 to October 2012 were recruited and the demographic characteristics, diagnosis and outcome were analyzed. Results: The study cohort included 264 patients over a 6 month period. More than half (55.6%) were aged between 15 and 40 years. There was a male predominance (56.8%). Majority of the patients (76.9%) presented with abdominal pain of less than 72 hour duration. The pain was sudden in onset in 54.9% of patients. Dull type was the most common character of pain (36%) followed by colicky type (22.3%). The most common site of pain was the lower abdomen (45.8%). Upper abdominal pain was seen in 26.9% and the pain was generalized in 27.3% of patients. The common causes were uretericcolic (16.3%), urinary tract infection (12.5%), acute pancreatitis (11%), acute appendicitis (10.6%) and acute gastritis (8%). More than half (51.9%) discharged from ED and 37% of cases were managed by the emergency physicians. Surgical intervention was required in 25.8% of patients. The mortality rate was 2.3%. Conclusions: Abdominal pain is a common ED symptom and clinicians must consider multiple diagnoses, especially those that require immediate intervention to limit morbidity and mortality.

    An 86-year-old man presented with severe pain in the upper abdomen along with fever. On physical examination, we found an arterial blood pressure of 84/43 mm Hg, a heart rate of 80 bpm and a temperature of 38.3°C. The abdomen was painful and peristalsis was absent. Empiric antibiotic therapy for sepsis was started with amoxicillin/clavulanate and gentamicin. CT scan of the abdomen revealed an emphysematous cholecystitis. Percutaneous ultrasound-guided cholecystostomy was applied. Bile cultures revealed Clostridium perfringens. Emphysematous cholecystitis is a life-threatening form of acute cholecystitis that occurs as a consequence of ischaemic injury to the gallbladder, followed by translocation of gas-forming bacteria (ie, C. perfringens, Escherichia coli, Klebsiella and Streptococci). The mortality associated with emphysematous cholecystitis is higher than in non-emphysematous cholecystitis (15% vs 4%). Therefore, early diagnosis with radiological imaging is of vital importance.

    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.

    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

  15. Acute Abdominal Pain after Intercourse: Adrenal Hemorrhage as the First Sign of Metastatic Lung Cancer

    PubMed Central

    2014-01-01

    Although the adrenal glands are a common site of cancer metastases, they are often asymptomatic and discovered incidentally on CT scan or autopsy. Spontaneous adrenal hemorrhage associated with metastatic lung cancer is an exceedingly rare phenomenon, and diagnosis can be difficult due to its nonspecific symptoms and ability to mimic other intra-abdominal pathologies. We report a case of a 65-year-old man with a history of right upper lobectomy seven months earlier for stage IB non-small cell lung cancer who presented with acute abdominal pain after intercourse. CT scan revealed a new right adrenal mass with surrounding hemorrhage, and subsequent FDG-PET scan confirmed new metabolic adrenal metastases. The patient's presentation of abdominal pain and adrenal hemorrhage immediately after sexual intercourse suggests that exertion, straining, or increased intra-abdominal pressure might be risk factors for precipitation of hemorrhage in patients with adrenal metastases. Management includes pain control and supportive treatment in mild cases, with arterial embolization or adrenalectomy being reserved for cases of severe hemorrhage. PMID:25126096

    Most cases of acute rheumatic fever (ARF) present with arthritis, carditis or choreiform movements. However, a variety of clinical manifestations which are not included in the modified Jones criteria can be the presenting symptoms of the disease. We describe a case of a 10-year-old boy with ARF who presented with recurrent episodes of abdominal and cervical pain who later developed an active carditis which established the diagnosis of ARF. A high degree of suspicion and an awareness of the less common manifestations of ARF are necessary to make an early diagnosis and initiate appropriate treatment in certain cases of ARF. PMID:3583777

    In a small number of patients with pancreas divisum (with stenotic minor papilla) a relative obstruction to pancreatic exocrine secretory flow results in pancreatitis. We report a 2-year-old boy presenting with recurrent bouts of abdominal pain. The diagnosis of acute pancreatitis was made based on blood biochemistry results. Ultrasound, computed tomography and magnetic resonance imaging showed several abdominal pseudocysts, peritoneal exsudate and confirmed pancreatitis but initially failed to reveal the aetiology. Ascites and cysts contained pancreatic enzymes. After weeks of combined conservative and surgical treatment, a magnetic resonance cholangiopancreaticography with secretin, showed a pancreas divisum with a cyst between the ducts of Santorini and Wirsung. Based on these findings, two endoscopic papillotomies (minor and major papilla) were performed. Three years follow-up was uneventful. In a child with recurrent pancreatitis or pancreatitis with chronic recurrent abdominal pain it is crucial to search aggressively for congenital abnormalities, including pancreas divisum. Secretin-enhanced magnetic resonance cholangiopancreaticography or diffusion-weighted magnetic resonance imaging is a valuable diagnostic tool for visualizing pancreatic duct anatomy. PMID:21299165

    AIM: To systematically review evidence on pathophysiology of intra-abdominal pressure (IAP) in acute pancreatitis (AP) with its clinical correlates. METHODS: Systematic review of available evidence in English literature with relevant medical subject heading terms on PubMed, Medline and Scopus with further search from open access sources on internet as suggested by articles retrieved. RESULTS: Intra-abdominal hypertension (IAH) is increasingly gaining recognition as a point of specific intervention with potential to alter disease outcome and improve mortality in AP. IAH can be expected in at least 17% of patients presenting with diagnosis of AP to a typical tertiary care hospital (prevalence increasing to 50% in those with severe disease). Abdominal compartment syndrome can be expected in at least 15% patients with severe disease. Recent guidelines on management of AP do not acknowledge utility of surveillance for IAP other than those by Japanese Society of Hepato-Biliary-Pancreatic Surgery. We further outline pathophysiologic mechanisms of IAH; understanding of which advances our knowledge and helps to coherently align common observed variations in management related conundrums (such as fluid therapy, nutrition and antibiotic prophylaxis) with potential to further individualize treatment in AP. CONCLUSION: We suggest that IAP be given its due place in future practice guidelines and that recommendations be formed with help of a broader panel with inclusion of clinicians experienced in management of IAH.

    Miano, Danielle I.; Silvis, Renee M.; Popp, Jill M.; Culbertson, Marvin C.; Campbell, Brendan; Smith, Sharon R.

    2015-01-01

    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

    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.

    AIM: To investigate whether seasonal changes had an effect on the incidence of acute appendicitis (AA) or nonspecific abdominal pain (NSAP). METHODS: We carried out a national register study of all patients with a hospital discharge diagnosis of AA and acute NSAP in Finland. Data were analyzed for the whole country and correlated to seasonal and weather parameters (temperature, humidity). Moreover, additional sub-analyses were performed for five geographically different area of Finland. RESULTS: The observation period spanned 21 years, with 186558 appendectomies, of which 137528 (74%) cases were reported as AA. The incidence of AA declined for 32% over the study period. The average incidence of the NSAP was 34/10000 per year. The mean annual temperature, but not relative humidity, showed clear geographical variations. The incidence of AA decreased significantly during the cold months of the year. No correlation was detected between temperature and incidence of NSAP. Humidity had a statistically significant impact on NSAP. CONCLUSION: The incidence of acute appendicitis is declining in Finland. We detected a clear seasonality in the incidence of AA and NSAP.

    Bacterial infections of the lungs and abdomen are among the most common causes of sepsis. Abdominal peritonitis often results in acute lung injury (ALI). Recent reports demonstrate a potential benefit of parenteral vitamin C [ascorbic acid (AscA)] in the pathogenesis of sepsis. Therefore we examined the mechanisms of vitamin C supplementation in the setting of abdominal peritonitis-mediated ALI. We hypothesized that vitamin C supplementation would protect lungs by restoring alveolar epithelial barrier integrity and preventing sepsis-associated coagulopathy. Male C57BL/6 mice were intraperitoneally injected with a fecal stem solution to induce abdominal peritonitis (FIP) 30 min prior to receiving either AscA (200 mg/kg) or dehydroascorbic acid (200 mg/kg). Variables examined included survival, extent of ALI, pulmonary inflammatory markers (myeloperoxidase, chemokines), bronchoalveolar epithelial permeability, alveolar fluid clearance, epithelial ion channel, and pump expression (aquaporin 5, cystic fibrosis transmembrane conductance regulator, epithelial sodium channel, and Na(+)-K(+)-ATPase), tight junction protein expression (claudins, occludins, zona occludens), cytoskeletal rearrangements (F-actin polymerization), and coagulation parameters (thromboelastography, pro- and anticoagulants, fibrinolysis mediators) of septic blood. FIP-mediated ALI was characterized by compromised lung epithelial permeability, reduced alveolar fluid clearance, pulmonary inflammation and neutrophil sequestration, coagulation abnormalities, and increased mortality. Parenteral vitamin C infusion protected mice from the deleterious consequences of sepsis by multiple mechanisms, including attenuation of the proinflammatory response, enhancement of epithelial barrier function, increasing alveolar fluid clearance, and prevention of sepsis-associated coagulation abnormalities. Parenteral vitamin C may potentially have a role in the management of sepsis and ALI associated with sepsis. PMID

    Even today, the diagnosis of acute abdominal pain represents a serious clinical problem. The medical knowledge in this field is characterized by uncertainty, imprecision and vagueness. This situation lends itself especially to be solved by the application of fuzzy logic. A fuzzy logic-based expert system for diagnostic decision support is presented (MEDUSA). The representation and application of uncertain and imprecise knowledge is realized by fuzzy sets and fuzzy relations. The hybrid concept of the system enables the integration of rule-based, heuristic and case-based reasoning on the basis of imprecise information. The central idea of the integration is to use case-based reasoning for the management of special cases, and rule-based reasoning for the representation of normal cases. The heuristic principle is ideally suited for making uncertain, hypothetical inferences on the basis of fuzzy data and fuzzy relations. PMID:7869951

    Introduction The incidence of acute gastrointestinal injury (AGI) after colorectal surgery is low when laparoscopic techniques are used. While elevated intra-abdominal pressure (IAP) and intra-abdominal hypertension (IAH) are associated with AGI grade II, little is known about the relation between increased IAP during laparoscopy and subsequent AGI. Aim To assess the impact of increased IAP during laparoscopic colorectal surgery on the incidence of postoperative AGI. Material and methods Sixty-six patients (41 men and 25 women) with colorectal cancer undergoing elective laparoscopic colorectal surgery were randomized into 3 groups, according to different IAP levels during CO2 pneumoperitoneum (10 mm Hg, 12 mm Hg and 15 mm Hg). We recorded the incidence of AGI after surgery by assessing the following parameters: time to first flatus/defecation, time to first bowel movement, time to tolerance of semi-liquid food and the occurrence of vomiting/diarrhea. Moreover, inflammatory mediators were measured before the induction of CO2 pneumoperitoneum and on postoperative day 1. Results Acute gastrointestinal injury occurred in 15 (27.3%) patients. In all 3 study groups, the elevation of IAP during CO2 pneumoperitoneum did not significantly increase the occurrence of symptoms of AGI, vomiting or diarrhea. Lower IAP levels did not significantly accelerate recovery of gastrointestinal function or shorten postoperative hospital stay. The changes in serum IL-6 after surgery did not correlate with the value of IAP. Conclusions The level of IAP elevation during laparoscopic colorectal surgery does not increase the occurrence of AGI after surgery. PMID:26240615

    Objective It has proved that muscle paralysis was more protective for injured lung in severe acute respiratory distress syndrome (ARDS), but the precise mechanism is not clear. The purpose of this study was to test the hypothesis that abdominal muscle activity during mechanically ventilation increases lung injury in severe ARDS. Methods Eighteen male Beagles were studied under mechanical ventilation with anesthesia. Severe ARDS was induced by repetitive oleic acid infusion. After lung injury, Beagles were randomly assigned into spontaneous breathing group (BIPAPSB) and abdominal muscle paralysis group (BIPAPAP). All groups were ventilated with BIPAP model for 8h, and the high pressure titrated to reached a tidal volume of 6ml/kg, the low pressure was set at 10 cmH2O, with I:E ratio 1:1, and respiratory rate adjusted to a PaCO2 of 35–60 mmHg. Six Beagles without ventilator support comprised the control group. Respiratory variables, end-expiratory volume (EELV) and gas exchange were assessed during mechanical ventilation. The levels of Interleukin (IL)-6, IL-8 in lung tissue and plasma were measured by qRT-PCR and ELISA respectively. Lung injury scores were determined at end of the experiment. Results For the comparable ventilator setting, as compared with BIPAPSB group, the BIPAPAP group presented higher EELV (427±47 vs. 366±38 ml) and oxygenation index (293±36 vs. 226±31 mmHg), lower levels of IL-6(216.6±48.0 vs. 297.5±71.2 pg/ml) and IL-8(246.8±78.2 vs. 357.5±69.3 pg/ml) in plasma, and lower express levels of IL-6 mRNA (15.0±3.8 vs. 21.2±3.7) and IL-8 mRNA (18.9±6.8 vs. 29.5±7.9) in lung tissues. In addition, less lung histopathology injury were revealed in the BIPAPAP group (22.5±2.0 vs. 25.2±2.1). Conclusion Abdominal muscle activity during mechanically ventilation is one of the injurious factors in severe ARDS, so abdominal muscle paralysis might be an effective strategy to minimize ventilator-induce lung injury.

    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.

    A 13-year-old boy with a history of bicycle handlebar injury to the left side of his abdomen was brought to the Emergency Department of our center. On admission, his vital signs were stable and abdominal examination revealed ecchymosis and tenderness of the injured areas. Mild to moderate free fluid and two small foci of free air in the anterior aspect of the abdomen, in favor of pneumoperitoneum, were detected in abdominopelvic sonography and CT-scan, respectively. In less than 6 hours, the patient developed generalized peritonitis. Therefore, exploratory laparotomy was promptly performed, which revealed appendiceal transection and rupture of the small bowel mesentery. Appendectomy and small bowel mesoplasty were done, with pathological diagnosis of acute appendicitis and periappendicitis. After surgery, the patient had a non-complicated hospital course. This rare case highlights the significance of the early management of appendiceal traumatic injuries in order to prevent further complicated events, especially in patients who are much more exposed to this risk due to their traumatic background.

    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

    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. PMID:26807068

    [Purpose] This study was conducted to investigate ultrasonically determined changes in the thickness of the transversus abdominis and internal oblique muscles during different sitting conditions. [Subjects and Methods] Twenty healthy men volunteered to participate in this study. Four different sitting conditions including (A) sitting, (B) sitting with left hip flexion, (C) sitting with an abdominal hollowing maneuver (AHM), and (D) sitting with an AHM and left hip flexion, were used. Subjective exercise difficulty was evaluated. [Results] Transversus abdominis and internal oblique muscle thicknesses significantly differed between conditions, with significantly greater thickness between positions from (A) to (D). Stability of the surface when sitting had no effect on the muscle thickness of the transversus abdominis. By contrast, sitting on an unstable surface caused an increase in muscle thickness of the internal oblique in each condition. The subjects reported progressively increasing difficulty in performing each exercise in a stable position from (A) to (D), while the difficulty in an unstable position was significantly different between (A) and (B), and between (C) and (D). [Conclusion] Our findings suggest that task (B) on a stable surface should be chosen for maximal activation of transversus abdominis without inducing overactivation of the internal oblique muscle.

    The regulation of ob gene expression in abdominal subcutaneous adipose tissue was investigated using a reverse transcription-competitive PCR method to quantify the mRNA level of leptin. Leptin mRNA level was highly correlated with the body mass index of 26 subjects (12 lean, 7 non-insulin-dependent diabetic, and 7 obese patients). The effect of fasting on ob gene expression was investigated in 10 subjects maintained on a hypocaloric diet (1045 KJ/d) for 5 d. While their metabolic parameters significantly changed (decrease in insulinemia, glycemia, and resting metabolic rate and increase in plasma ketone bodies), the caloric restriction did not modify the leptin mRNA level in the adipose tissue. To verify whether insulin regulates ob gene expression, six lean subjects underwent a 3-h euglycemic hyperinsulinemic (846 +/- 138 pmol/liter) clamp. Leptin and Glut 4 mRNA levels were quantified in adipose tissue biopsies taken before and at the end of the clamp. Insulin infusion produced a significant threefold increase in Glut 4 mRNA while leptin mRNA was not affected. It is concluded that ob gene expression is not acutely regulated by insulin or by metabolic factors related to fasting in human abdominal subcutaneous adipose tissue. PMID:8755631

    Objective Higher body mass index (BMI) is associated with increased risk of acute kidney injury (AKI) after major trauma. Since BMI is non-specific, reflecting lean, fluid, and adipose mass, we evaluated the use of computed tomography (CT) to determine if abdominal adiposity underlies the BMI-AKI association. Design Prospective cohort study. Setting Level I Trauma Center of a university hospital. Patients Patients older than 13 years with an Injury Severity Score ≥16 admitted to the trauma intensive care unit were followed for development of AKI over five days. Those with isolated severe head injury or on chronic dialysis were excluded. Interventions None Measurements and Main Results Clinical, anthropometric, and demographic variables were collected prospectively. CT images at the level of the L4-5 intervertebral disc space were extracted from the medical record and used by two operators to quantitate visceral and subcutaneous adipose tissue (VAT and SAT, respectively) areas. AKI was defined by Acute Kidney Injury Network (AKIN) creatinine and dialysis criteria. Of 400 subjects, 327 (81.8%) had CT scans suitable for analysis: 264/285 (92.6%) blunt trauma subjects, 63/115 (54.8%) penetrating trauma subjects. VAT and SAT areas were highly correlated between operators (ICC>0.999, p<0.001 for each) and within operator (ICC>0.999, p<0.001 for each). In multivariable analysis, the standardized risk of AKI was 15.1% (95% CI 10.6%,19.6%), 18.1% (14%,22.2%), and 23.1% (18.3%,27.9%) at the 25th, 50th, and 75th percentiles of VAT area, respectively (p=0.001), with similar findings when using SAT area as the adiposity measure. Conclusions Quantitation of abdominal adiposity using CT scans obtained for clinical reasons is feasible and highly reliable in critically ill trauma patients. Abdominal adiposity is independently associated with AKI in this population, confirming that excess adipose tissue contributes to the BMI-AKI association. Further studies of the potential

    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. PMID:26453370

    Diverticulum of the caecum is a rare lesion. From a clinical point of view, the inflammation it causes can mimic symptoms of acute appendicitis, causing difficulties in diagnosis and thus prescription of appropriate treatment. It is almost impossible to differentiate this disease from acute appendicitis through physical examination alone, and radiological imaging may also prove insufficient.

    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

    One hundred eighty-six patients with suspected acute cholecystitis (AC) underwent radionuclide hepatobiliary imaging with technetium Tc 99m-iprofenin to assess the ability of this tracer to detect AC. After intravenous injection of 5 to 10 mCi of this agent, 500,000 count anterior images were obtained at ten-minute intervals for 60 minutes. An abnormal hepatobiliary scan (HBS) diagnostic of AC was defined as one in which the common bile duct, but not the gallbladder, visualized within one hour of tracer administration. In this series, the sensitivity and specificity for HBS in the detection of AC were 97 and 87%, respectively. The hepatobiliary scan should be the procedure of choice for the rapid detection of AC. It is simple, rapid, and safe to perform, enabling a diagnosis to be established within one hour.

    Objectives: Temporary abdominal closure methods allow for management of open abdomens where immediate primary closure is not possible and/or where repeat abdominal entries are necessary. We assessed pressure mapping and fluid extraction efficiency of three open abdomen dressing systems: ABThera™ Active Abdominal Therapy System, V.A.C.® Abdominal Dressing System, and Barker’s vacuum packing technique. Methods: An in vitro test model was designed to simulate physical conditions present in an open abdomen. The model consisted of a rigid rest platform with elevated central region and a flexible outer layer with centrally located incision. Constant −125 mmHg negative pressure was applied according to the type of system, under simulated dynamic conditions, using albumin-based solution with a viscosity of 14 cP. Data were collected by pressure sensors located circumferentially into three concentric zones: Zone 1 (closest to negative pressure source), Zone 2 (immediately outside of manifolding material edge), and Zone 3 (area most distal from negative pressure source). Each value was the result of approximately 100 pressure readings/zone/experiment with a total of three experiments for each system. Results: Pressure distribution of ABThera Therapy was significantly (p < 0.05) superior to Barker’s vacuum packing technique in all three evaluated zones. Similarly, V.A.C. Abdominal Dressing System pressure distribution was significantly (p < 0.05) improved compared to Barker’s vacuum packing technique in all zones. There were no pressure distribution differences in Zone 1 between ABThera Therapy and V.A.C. Abdominal Dressing System; however, in Zones 2 and 3, ABThera Therapy was significantly (p < 0.05) superior to V.A.C. Abdominal Dressing System. Conclusions: These data suggest that all approaches to negative pressure therapy for open abdomen treatment are not equal. Additional research should be conducted to elucidate clinical implications of data

  12. Acute abdominal compartment syndrome as a complication of Holmium laser enucleation of the prostate: a case report

    PubMed Central

    2014-01-01

    Background In 1996, Holmium laser enucleation of the prostate was introduced and has been shown to be safe and highly effective. Case presentation We report a case of a rare complication that resulted in intra-abdominal compartment syndrome with prolonged intubation and intensive care, involving an 74-year-old male after holmium laser enucleation of prostate, with a massive irrigant fluid leakage into the retroperitoneal space. The elevated abdominal pressure was reduced by forced diuresis. The tracheal tube was removed 18 hours after the patient’s transfer to the ICU. The patient was discharged to home one week after the operation. Conclusion In rare cases when no obvious ruptures of the prostate capsule or the bladder occur during laser enucleation of prostate, knowledge regarding possible emersion of massive amounts of irrigant fluid into the retroperitoneal space leading to intra-abdominal compartment syndrome aids in the diagnosis and subsequent successful therapy of intra-abdominal hypertension.

    Poor condition subarachnoid hemorrhage (SAH) patients present a high mortality and morbidity. In this study, we reviewed the acute interventional (surgical and endovascular) management of 109 SAH-poor condition patients, who were treated as early as logistically possible after confirming stable circulation parameters. Patients over the age of 70 years, without clinical response to painful stimulation were excluded. We recognized at least 3 different postinterventional therapeutic approaches: (1) Norm- or hypovolemic, normotensive hemodilution in 30 patients with space-occupying intracranial hematomas as well as in 31 cases with acute cerebro-spinal-fluid obstruction. (2) Normovolemic, hypertensive hemodilution after unilateral decompressive craniotomy in 23 surgical- and 2 endovascular-treated patients with focalized space occupying lesions and reduced cerebral perfusion. (3) Hypovolemic, normo-, or hypertensive hemodilution after bilateral decompressive craniotomy in 23 cases with massive brain-swelling. We observed a reduced mortality (21%). The overall late outcome was favorable in 56% and unfavorable in 23%. Selective aggressive treatment adapted to increase the cerebral perfusion, seems to be an effective therapy to improve the survival and outcome of several poor condition SAH-patients. PMID:18200827

    Older adults presenting with acute coronary syndromes (ACSs) often have multiple chronic conditions (MCCs). In addition to traditional cardiovascular (CV) risk factors (ie, hypertension, hyperlipidemia, and diabetes), common CV comorbidities include heart failure, stroke, and atrial fibrillation, whereas prevalent non-CV comorbidities include chronic kidney disease, anemia, depression, and chronic obstructive pulmonary disease. The presence of MCCs affects the presentation (eg, increased frequency of type 2 myocardial infarctions [MIs]), clinical course, and prognosis of ACS in older adults. In general, higher comorbidity burden increases mortality following MI, reduces utilization of ACS treatments, and increases the importance of developing individualized treatment plans.

    Appendicitis (APP) and gall bladder diseases (GBD) are the most frequent non-obstetric indications for urgent surgery among pregnant women. The aim was to present the diagnosis, treatment and potential complications of APP and symptomatic GBD. We searched the literature for APP and GBD during pregnancy and presented the results in the form of a review article. APP symptoms among pregnant women are comparable to these in the general population. Typical clinical symptoms are present in 50-75% of cases. Laboratory tests are useful for a differential diagnosis. The imaging of choice is an ultrasonography scan, but magnetic resonance is of the highest accuracy The final diagnosis is difficult. When the surgery is delayed, the risk of appendix perforation increases and thus complications are more frequent. GBD symptoms and signs are comparable to those in the general population. The best imaging is an ultrasonography scan, and laboratory tests are important in a jaundice differential diagnosis. In cases with symptomatic GBD, a delay in surgery is associated with an increased risk of complications (pancreatitis, abortion, intrauterine death). The treatment method of choice for APP and symptomatic GBD is surgery both laparotomy and laparoscopy (preferred), which are considered relatively safe, though laparoscopy compared to laparotomy for APP can be associated with a higher risk of abortion. Untreated or delayed APP and symptomatic GBD treatment during pregnancy increases the risk of complications, both for the woman and the fetus. Diagnosis is difficult and should be based on a multidisciplinary approach to the patient. Surgery by laparotomy or laparoscopy is relatively safe. PMID:24505953

    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). For abdominal ultrasonography alone sensitivity was only 50% (95%CI 9.5–90.6%), with

    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.

    A 21-year-old female presented at an emergency department with abdominal pain and nausea. Computed tomography (CT) of the chest and abdomen revealed a small amount of mediastinal emphysema in the precardiac area, but the underlying cause could not be identified. On admission, her plasma glucose was 371 mg/dl, glycated hemoglobin (HbA1c) was 14.0%, and blood pH was 6.91. These findings supported a diagnosis of Hamman's syndrome associated with diabetic ketoacidosis. Her diabetic ketoacidosis was managed with insulin and fluid therapy, and the mediastinal emphysema disappeared spontaneously by the time of discharge. Presence of free air of the chest and abdominal cavity must warrant a differential diagnosis of gastrointestinal perforation; however, when the free air is accompanied by diabetic ketoacidosis, it is not necessary to perform urgent endoscopy.

    Acute epiploic appendagitis most commonly manifests with acute lower quadrant pain. Its clinical features are similar to those of acute diverticulitis or, less commonly, acute appendicitis. The conditions that may mimic acute epiploic appendagitis at computed tomography (CT) include acute omental infarction, mesenteric panniculitis, fat-containing tumor, and primary and secondary acute inflammatory processes in the large bowel (eg, diverticulitis and appendicitis). Whereas the location of acute epiploic appendagitis is most commonly adjacent to the sigmoid colon, acute omental infarction is typically located in the right lower quadrant and often is mistaken for acute appendicitis. It is important to correctly diagnose acute epiploic appendagitis and acute omental infarction on CT images because these conditions may be mistaken for acute abdomen, and the mistake may lead to unnecessary surgery. The CT features of acute epiploic appendagitis include an oval lesion 1.5-3.5 cm in diameter, with attenuation similar to that of fat and with surrounding inflammatory changes, that abuts the anterior sigmoid colon wall. The CT features of acute omental infarction include a well-circumscribed triangular or oval heterogeneous fatty mass with a whorled pattern of concentric linear fat stranding between the anterior abdominal wall and the transverse or ascending colon. As CT increasingly is used for the evaluation of acute abdomen, radiologists are likely to see acute epiploic appendagitis and its mimics more often. Recognition of these conditions on CT images will allow appropriate management of acute abdominal pain and may help to prevent unnecessary surgery. PMID:16284132

    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

    A 60-year-old woman was transfer-red to the emergency department of our medical center with worsening chest and back pain. Computed tomography revealed Stanford type B aortic dissection. There was a false lumen from the distal arch to the abdominal aorta just above the celiac artery. Although she was at 1st treated conservatively, she abruptly developed acute renal failure and lower limb ischemia because of an enlarged false lumen, and emergency axillo-femoral bypass surgery was performed with an 8 mm tube graft. However, renal failure gradually worsened, which necessitated continuous hemodiafiltration was performed. Thoracic endovascular aortic repair was then performed, and her renal function recovered.

    Objectives To evaluate the feasibility of dose-modulated retrospective ECG-gated thoracoabdominal aorta CT angiography (CTA) assessing abdominal aortic intimal flap motion and investigate the motion characteristics of intimal flap in acute aortic dissection (AAD). Materials and Methods 49 patients who had thoracoabdominal aorta retrospective ECG-gated CTA scan were enrolled. 20 datasets were reconstructed in 5% steps between 0 and 95% of the R-R interval in each case. The aortic intimal flap motion was assessed by measuring the short axis diameters of the true lumen and false lumen 2 cm above of celiac trunk ostium in different R-R intervals. Intimal flap motion and configuration was assessed by two independent observers. Results In these 49 patients, 37 had AAD, 7 had intramural hematoma, and 5 had negative result for acute aortic disorder. 620 datasets of 31 patients who showed double lumens in abdominal aorta were enrolled in evaluating intimal flap motion. The maximum and minimum true lumen diameter were 12.2±4.1 mm (range 2.6∼17.4) and 6.7±4.1 mm (range 0∼15.3) respectively. The range of intimal flap motion in all patients was 5.5±2.6 mm (range 1.8∼10.2). The extent of maximum true lumen diameter decreased during a cardiac cycle was 49.5%±23.5% (range 12%∼100%). The maximum motion phase of true lumen diameter was in systolic phase (5%∼40% of R-R interval). Maximum and minimum intimal flap motion was at 15% and 75% of the R-R interval respectively. Intimal flap configuration had correlation with the phase of cardiac cycle. Conclusions Abdominal intimal flap position and configuration varied greatly during a cardiac cycle. Retrospective ECG-gated thoracoabdominal aorta CTA can reflect the actual status of the true lumen and provide more information about true lumen collapse. This information may be helpful to diagnosis and differential diagnosis of dynamic abstraction. PMID:24503676

    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. PMID:9737070

    Despite the frequency of functional abdominal pain, potentially dangerous causes of abdominal pain need to be excluded. Medical history and clinical examination must focus on red flags and signs for imflammatory or malignant diseases. See the patient twice in the case of severe and acute abdominal pain if lab parameters or radiological examinations are normal. Avoid repeated and useless X-ray exposure whenever possible. In the case of subacute or chronic abdominal pain, lab tests such as fecal calprotectin, helicobacter stool antigen and serological tests for celiac disease are very useful. Elderly patients may show atypical or missing clinical signs. Take care of red herrings and be skeptical whether your initial diagnosis is really correct. Abdominal pain can frequently be an abdominal wall pain. PMID:26331201

    Objective Rupture of abdominal aortic aneurysm (AAA), a major cause of death in the aged population, is characterized by vascular inflammation and matrix degradation. Serum amyloid A (SAA), an acute phase reactant linked to inflammation and matrix metalloproteinase induction, correlates with aortic dimensions before aneurysm formation in humans. We investigated whether SAA deficiency in mice impacts AAA formation during angiotensin II (AngII) infusion. Approach and Results Plasma SAA increased ~60-fold in apoE−/− mice 24 hours after i.p. AngII injection (100 μg/kg; n = 4) and ~15-fold after chronic 28-day AngII infusion (1,000 ng/kg/min; n = 9). AAA incidence and severity after 28-day AngII infusion was significantly reduced in apoE−/− mice lacking both acute phase SAA isoforms (SAAKO; n = 20) compared to apoE−/− mice (SAAWT; n = 20) as assessed by in vivo ultrasound and ex vivo morphometric analyses, despite a significant increase in systolic blood pressure in SAAKO mice compared to SAAWT mice after AngII infusion. Atherosclerotic lesion area of the aortic arch was similar in SAAKO and SAAWT mice after 28-day AngII infusion. Immunostaining detected SAA in AAA tissues of AngII-infused SAAWT mice that co-localized with macrophages, elastin breaks, and enhanced matrix metalloproteinase (MMP) activity. MMP-2 activity was significantly lower in aortas of SAAKO mice compared to SAAWT mice after 10-day AngII infusion. Conclusion Lack of endogenous acute phase SAA protects against experimental AAA through a mechanism that may involve reduced MMP-2 activity. PMID:25745063

    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.

    The aim of this study was to assess the efficacy and safety of postoperative pain relief using tramadol and ketorolac in continuous intravenous infusion. The 585 patients included in the study underwent major surgery according to a protocol involving the parenteral administration of 100 mg tramadol approximately 40 min before the end of surgery. This was followed by the continuous intravenous infusion of 600 mg tramadol and 180 mg ketorolac diluted with physiological solution to a total volume of 96 ml. Delivery was carried out using an elastomeric pump or a syringe pump and administered over a 48-hour period at a constant rate of 2 ml/h. Any further doses consisted of 100 mg tramadol up to a maximum of 300 mg over a 24-h period. Pain was assessed on a verbal numeric scale (VNS). For each patient the intensity of pain was assessed both at rest and on movement (coughing, deep breathing, movement of lower limbs). At the scheduled times (T0-T72, every 6 h), the following parameters were evaluated: hemodynamic stability; respiratory function; the appearance of any side effects; the level of sedation; and the need for any further doses of analgesic. The analysis of the data obtained showed the good quality of postoperative pain relief achieved: pain intensity at rest was, on average, always below VNS level 3, while during movement it always had an average VNS level of 3-4. The only side effects found with any frequency were nausea (22.6%) and vomiting (8.5%); hemodynamic and respiratory parameters remained stable. The method adopted was of limited cost and was well accepted by both patients and staff. On the basis of the data obtained, it is possible to affirm that the post-operative pain protocol proposed is effective, safe, without significant side effects, and of limited cost. Therefore, it is the first choice protocol for our operating unit after major abdominal surgery. PMID:12224377

    When should a patient with abdominal pain be referred to the emergency ward? The following goals must be achieved upon managing patients with acute abdominal pain: 1) identify vital emergency situations; 2) detect surgical conditions that require emergency referral without further diagnostic procedures; 3) in "non surgical acute abdomen patients" perform appropriate diagnostic procedures, or in selected cases delay tests and reevaluate the patient after an observation period, after which a referral decision is made. Clues from the history and physical examination are critical to perform this evaluation. A good knowledge of the most frequent acute abdominal conditions, and identifying potential severity criteria allow an appropriate management and decision about emergency referral. PMID:20873434

    Chronic abdominal pain is a common pediatric condition affecting 20% of the pediatric population worldwide. Most children with this disorder are found to have no specific organic etiology and are given the diagnosis of functional abdominal pain. Well-designed clinical trials have found hypnotherapy and guided imagery to be the most efficacious treatments for this condition. Hypnotic techniques used for other somatic symptoms are easily adaptable for use with functional abdominal pain. The author discusses 2 contrasting hypnotic approaches to functional abdominal pain and provides implications for further research. These approaches may provide new insights into this common and complex disorder. PMID:21922712

    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.

    Introduction We present the case of a 37-year old woman diagnosed with intravenous leiomyomatosis (IVL) that was managed uneventfully with multiple-step management. Presentation of case A 37-year-old woman was admitted because of acute abdominal pain. Emergency Computed Tomography demonstrated a big pelvic mass 5 × 15 cm of heterogenous composition intaking the contrast agent. Total hysterectomy with salpingoophorectomy was proposed to patient, however, patient expressed her will for fertility preservation and gave consent only for the resection of a single ovary. Laparotomy revealed the presence of myoma, multiple lesions of potential adenomyosis and cordon-shaped formations arising from uterus and extending mainly to left ovary. Final histological diagnosis was intravenous leiomyomatosis (IVL). MRI angiography revealed the presence of residual lesions in inferior vena cava. Laparoscopic resection was performed one month after laparotomy and left ovary was resected without complications. Venovenous bypass was finally performed three months later from initial surgery. The process was significantly labored, resulted in the successful resection of intravenous lesions but was complicated intraoperatively by right kidney rupture. After a follow-up of 33 months, case remains uncomplicated without signs or symptoms of potential recurrence. Discussion Intravenous leiomyomatosis represents a rare clinical entity histologically bening but clinically aggressive. No consensus exists regarding the optimal management, especially in cases with initial will for fertility preservation. Conclusion IVL represents a rare clinical entity often presenting difficulties in diagnosis and optimal treatment. Large case-series studies should be encouraged to assess the optimal management.

  17. The biological effects of higher and lower positive end-expiratory pressure in pulmonary and extrapulmonary acute lung injury with intra-abdominal hypertension

    PubMed Central

    2014-01-01

    Introduction Mechanical ventilation with high positive end-expiratory pressure (PEEP) has been used in patients with acute respiratory distress syndrome (ARDS) and intra-abdominal hypertension (IAH), but the role of PEEP in minimizing lung injury remains controversial. We hypothesized that in the presence of acute lung injury (ALI) with IAH: 1) higher PEEP levels improve pulmonary morphofunction and minimize lung injury; and 2) the biological effects of higher PEEP are more effective in extrapulmonary (exp) than pulmonary (p) ALI. Methods In 48 adult male Wistar rats, ALIp and ALIexp were induced by Escherichia coli lipopolysaccharide intratracheally and intraperitoneally, respectively. After 24 hours, animals were anesthetized and mechanically ventilated (tidal volume of 6 mL/kg). IAH (15 mmHg) was induced and rats randomly assigned to PEEP of 5 (PEEP5), 7 (PEEP7) or 10 (PEEP10) cmH2O for 1 hour. Results In both ALIp and ALIexp, higher PEEP levels improved oxygenation. PEEP10 increased alveolar hyperinflation and epithelial cell damage compared to PEEP5, independent of ALI etiology. In ALIp, PEEP7 and PEEP10 increased lung elastance compared to PEEP5 (4.3 ± 0.7 and 4.3 ± 0.9 versus 3.1 ± 0.3 cmH2O/mL, respectively, P <0.01), without changes in alveolar collapse, interleukin-6, caspase-3, type III procollagen, receptor for advanced glycation end-products, and vascular cell adhesion molecule-1 expressions. Moreover, PEEP10 increased diaphragmatic injury compared to PEEP5. In ALIexp, PEEP7 decreased lung elastance and alveolar collapse compared to PEEP5 (2.3 ± 0.5 versus 3.6 ± 0.7 cmH2O/mL, P <0.02, and 27.2 (24.7 to 36.8) versus 44.2 (39.7 to 56.9)%, P <0.05, respectively), while PEEP7 and PEEP10 increased interleukin-6 and type III procollagen expressions, as well as type II epithelial cell damage compared to PEEP5. Conclusions In the current models of ALI with IAH, in contrast to our primary hypothesis, higher PEEP is more effective in

    Introduction Ostriches typically avoid humans in the wild, since they correctly assess humans as potential predators, and, if approached, often run away. However, ostriches may turn aggressive rather than run when threatened, especially when cornered, and may also attack when they feel the need to defend their offspring or territories. Presentation of case A 71-year-old male patient presented with intra abdominal injury sustained from being kicked in the abdominal wall by an ostrich. During laparotomy, were found free peritoneal effusion and perforation of the small intestine. Discussion The clinical history and physical examination are extremely important for diagnostic and therapeutic decision making. CT-scan is the most accurate exam for making diagnosis. Surgery is the treatment of choice, and is always indicated when there is injury to the hollow viscera. In general it is possible to suture the defect. Conclusion In cases of blunt abdominal trauma by animals is necessary to have a low threshold of suspicion for acute abdomen. PMID:25685344

    We present the case of a 43-year-old gentleman who presented to the emergency room with acute abdominal distension, confusion and vascular collapse. The emergent radiologic imaging obtained showed massive bilateral adrenal enlargement, but despite the initial clinical suspicion of possible overwhelming sepsis and/or massive abdominal/intralesional hemorrhage, lab tests based obtained rapidly confirmed the diagnosis of acute Addisonian crisis which responded dramatically to adrenocorticoid hormone replacement therapy and aggressive fluid resuscitation. The patient's established history of metastatic lung cancer confirmed this as a case of metastatic massive bilateral adrenal metastases with an initial presentation of acute adrenal insufficiency which is uncommon in the setting of metastatic carcinomatosis but more typically associated with lymphomas. Recognition of this clinical possibility is vital to enable rapid diagnosis and consequent life saving therapy. PMID:27328473

  4. Remote ischemic conditioning for acute ischemic stroke: dawn in the darkness.

    2016-07-01

    Stroke is a leading cause of disability with high morbidity and mortality worldwide. Of all strokes, 87% are ischemic. The only approved treatments for acute ischemic stroke are intravenous thrombolysis with alteplase within 4.5 h and thrombectomy within 8 h after symptom onset, which can be applied to just a few patients. During the past decades, ischemic preconditioning has been widely studied to confirm its neuroprotection against subsequent ischemia/reperfusion injury in the brain, including preconditioning in situ or in a remote organ (such as a limb) before onset of brain ischemia, the latter of which is termed as remote ischemic preconditioning. Because acute stroke is unpredicted, ischemic preconditioning is actually not suitable for clinical application. So remote ischemic conditioning performed during or after the ischemic duration of the brain was then designed to study its neuroprotection alone or in combination with alteplase in animals and patients, which is named as remote ischemic perconditioning or remote ischemic postconditioning. As expected, animal experiments and clinical trials both showed exciting results, indicating that an evolution in the treatment for acute ischemic stroke may not be far away. However, some problems or disputes still exist. This review summarizes the research progress and unresolved issues of remote ischemic conditioning (pre-, per-, and post-conditioning) in treating acute ischemic stroke, with the hope of advancing our understanding of this promising neuroprotective strategy for ischemic stroke in the near future.

    The aim of this study was to carry out a comparative study of water balance and water protein composition of the blood during exposure to acute (abrupt restriction of motor activity) and ordinary rigorous bed rest of 7 days. The studies were performed on 30 long distance runners aged 22-25 years old who had a VO 2 max of 66 ml kg -1·min -1 on the average. The volunteers were divided into three equal groups: the volunteers in the 1st group were under a normal ambulatory life conditions (control subjects), the volunteers of the 2nd group subjected to an acute bed rest (abrupt restriction of motor activity) regime (acute bed rested subjects) and the volunteers of the 3rd group were submitted to ordinary and rigorous bed rest (rigorous bed rested subjects). All volunteers were on an average of 13.8 km/day before taking part in this investigation. The 2nd and 3rd groups of volunteers were kept under a rigorous bed rest regime for 7 days. During the prebed rest period and actual bed rest period plasma volume (PV), total protein and protein fractions (albumins and globulins) and hematocrit were measured. Exposure to acute bed rest conditions induced a significant increase in hematocrit, hemoglobin concentration, protein fractions and marked decrease in (PV) and water balance which were significantly more pronounced than during exposure to ordinary rigorous bed rest. It was concluded that exposure to acute bed rest conditions induces significantly greater changes in water balance and water-protein concentration of the blood of endurance trained volunteers than exposure to ordinary rigorous bed rest conditions.

    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

    Acute acalculous cholecystitis and acute hemorrhagic cystitis due to Salmonella Typhi are a rare condition. A 24-year-old female patient was admitted to our clinic with abdominal pain, nausea, fever, headache, urinary burning, and bloody urine. Based on clinical, laboratory, and radiological evaluations, the patient was diagnosed with acute acalculous cholecystitis and acute hemorrhagic cystitis due to Salmonella Typhi. The patient was treated with intravenous ceftriaxone for two weeks. After the treatment, the patient's clinical and laboratory findings improved. Acute acalculous cholecystitis due to Salmonella Typhi concomitant with acute hemorrhagic cystitis is very rare and might be difficult to diagnose. Infectious agents such as Salmonella Typhi should be considered when acute acalculous cholecystitis and acute hemorrhagic cystitis are detected in adult patients with no underlying diseases.

    Background Opiates affect blood factors as well as pain and inflammation in a gender-dependent manner. The aim of the present study was to evaluate the effects of morphine on serum glucose, cholesterol, triglycerides, and urea in gonadectomized and inflammation conditions. Methods Animals were divided as follows: control group, carrageenan and chronic morphine recipients, acute morphine recipients, chronic morphine recipients, carrageenan recipients, acute morphine and carrageenan recipients, gonadectomized group, gonadectomized recipients of carrageenan, gonadectomized recipients of morphine, gonadectomized recipients of chronic morphine, gonadectomized recipients of carrageenan and chronic morphine, gonadectomized recipients of acute morphine and carrageenan. Findings Our results have shown that acute and chronic morphine elevates blood glucose level in the acute and chronic morphine group. Cholesterol level has shown to be increasing in the morphine and carrageenan recipient group compared with a group which merely received morphine. Triglyceride has shown to be decreasing in acute and chronic morphine recipient group compared with control group. A significant increase in serum urea was observed in acute and chronic morphine recipients compared with the carrageenan recipient group. Conclusion Morphine alters the serum glucose, cholesterol, triglyceride, and urea in the normal and inflammatory conditions differently, hence, this finding should be considered in the patients who use morphine as a relief of pain, especially in an inflammatory condition.

    2011-01-01

    Background: Endometriosis is a common condition in women that affects up to 45% of patients in the reproductive age group by causing pelvic pain. It is characterized by the presence of endometrial tissue outside the uterine cavity and is rarely found subcutaneously or in abdominal incisions, causing it to be overlooked in patients with abdominal pain. Methods: A 45-year-old woman presented with lower abdominal pain 2 years following a laparoscopic supracervical hysterectomy. She was found to have incidental cholelithiasis and a large abdominal mass suggestive of a significant ventral hernia on CT scan. Results: Due to the peculiar presentation, surgical intervention took place that revealed a large 9cm×7.6cm×6.2cm abdominal wall endometrioma. Conclusion: Although extrapelvic endometriosis is rare, it should be entertained in the differential diagnosis for the female patient who presents with an abdominal mass and pain and has a previous surgical history.

    The current definitive treatment for acute or chronic liver condition, that is, cirrhosis, is liver transplantation from a limited number of donors, which might cause complications after donation. Hence, bone marrow stem cell transplantation has been developed, but the risk of carcinogenesis remains. We have recently developed a protocol for hepatic differentiation of CD117(+) stem cells from human exfoliated deciduous teeth (SHED). In the present study, we examine whether SHED hepatically differentiated (hd) in vitro could be used to treat acute liver injury (ALI) and secondary biliary cirrhosis. The CD117(+) cell fraction was magnetically separated from SHED and then differentiated into hepatocyte-like cells in vitro. The cells were transplanted into rats with either ALI or induced secondary biliary cirrhosis. Engraftment of human liver cells was determined immunohistochemically and by in situ hybridization. Recovery of liver function was examined by means of histochemical and serological tests. Livers of transplanted animals were strongly positive for human immunohistochemical factors, and in situ hybridization confirmed engraftment of human hepatocytes. The tests for recovery of liver function confirmed the presence of human hepatic markers in the animals' blood serum and lack of fibrosis and functional integration of transplanted human cells into livers. No evidence of malignancy was found. We show that in vitro hdSHED engraft morphologically and functionally into the livers of rats having acute injury or secondary biliary cirrhosis. SHED are readily accessible adult stem cells, capable of proliferating in large numbers before differentiating in vitro. This makes SHED an appropriate and safe stem cell source for regenerative medicine. PMID:25234861

    First cause of secondary hypertension is renovascular hypertension which presents abdominal bruit in 16 to 20% of cases. This clinical sign is also associated with other vascular disease of the abdomen such as celiac trunk stenosis and/or aneurysms located on the pancreaticoduodenal or gastroduodenal arcs level, with little representation among aneurysm. They usually appear on a context of digestive complications like neoplasias, chronic pancreatitis or gastric obstructions possibly with obstructive icterus, hemorrhage and acute abdomen episodes. Its presentation in other contexts is rare and constitutes a diagnostic challenge. Diagnosis is made by abdominal arteriography which is the best method because you can locate the problem as well as intervene therapeutically with embolization of the aneurysme. We would like to emphasize the importance of a quick diagnosis due to the risk of rupture and the high morbi-mortality associated. PMID:15219082

    2013-04-01

    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

    Abstract Objective To investigate potential differences in the availability of medicines for chronic and acute conditions in low- and middle-income countries. Methods Data on the availability of 30 commonly-surveyed medicines – 15 for acute and 15 for chronic conditions – were obtained from facility-based surveys conducted in 40 developing countries. Results were aggregated by World Bank country income group and World Health Organization region. Findings The availability of medicines for both acute and chronic conditions was suboptimal across countries, particularly in the public sector. Generic medicines for chronic conditions were significantly less available than generic medicines for acute conditions in both the public sector (36.0% availability versus 53.5%; P = 0.001) and the private sector (54.7% versus 66.2%; P = 0.007). Antiasthmatics, antiepileptics and antidepressants, followed by antihypertensives, were the drivers of the observed differences. An inverse association was found between country income level and the availability gap between groups of medicines, particularly in the public sector. In low- and lower-middle income countries, drugs for acute conditions were 33.9% and 12.9% more available, respectively, in the public sector than medicines for chronic conditions. Differences in availability were smaller in the private sector than in the public sector in all country income groups. Conclusion Current disease patterns do not explain the significant gaps observed in the availability of medicines for chronic and acute conditions. Measures are needed to better respond to the epidemiological transition towards chronic conditions in developing countries alongside current efforts to scale up treatment for communicable diseases.

    The aim of the present study is, to describe the morbidity and mortality of 196 patients with an acute abdominal condition who underwent surgery at the Department of Gynecology and Obstetrics of the TU Munich between 1982 and 1986. This is a percentage of 2.7 of all 7,167 operations carried out during this period. 118 of these patients had an extrauterine pregnancy and were therefore excluded from the study. The second group of 79 patients, mostly with inflammatory diseases, were analyzed. In most of these cases the acute abdominal condition was caused by a tuboovarian abscess (48.1%), followed by peritonitis because of a bowel-disease (11.4%). 6 patients suffered from an abscessing endometritis due to a caesarean section with sepsis in 5 cases. A generalized peritonitis occurred in 5 cases and was treated with a planned relaparatomy with lavage. 63% of the patients had no complications within 28 days after operation, 13% developed a subileus; in 7% a relaparatomy was necessary. 6% of the patients had problems of wound-healing. One patient with stomach-cancer died 3 weeks after the operation because of a fulminant lung-embolism. Thus the mortality rate was 1.5%. A further 27% were treated at the intensive care-unit and 18% needed artificial respiration. The average postoperative period of hospitalisation was 15 days. In comparison, patients with elective operations remained 13 days. The morbidity and mortality of patients due to surgery of an acute abdominal condition was relatively small; postoperative complications could be well treated in all cases and is probably the result of a positive and early indication for surgical intervention.

    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.

    Reduced intensity conditioning (RIC) regimens have been used extensively in adults with hematological malignancies. To address whether this is a feasible approach for children with acute lymphoblastic leukemia (ALL), we evaluated transplant outcomes in 38 recipients transplanted from 1995–2005 for whom this was their first transplant. The median age at transplant was 12 years and 47% had performance scores <90%. Disease status was first complete remission (CR) in 13%, ≥CR2 in 60% of patients and 22% had active disease at transplantation. Matched related donors were available for a third of patients and about half of whom received bone marrow (BM) and the others, peripheral blood progenitor cells (PBPC). Sixty percent of unrelated donor transplant recipients received PBPC. The day-100 probability of grade 2–4 acute GVHD was 37% and the 3-year probability of chronic GVHD, 26%. At 3-years, the probability of transplant related mortality was 40%, relapse, 37% and disease-free survival (DFS), 30%. These data indicate long-term DFS can be achieved using RIC regimens in children with ALL. Given the relatively small cohort, these findings must be validated in a larger population. PMID:20302960

    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

    Intra-abdominal hypertension (IAH) and abdominal compartment syndrome (ACS) are rare but potentially morbid diagnoses. Clinical index of suspicion for these disorders should be raised following massive resuscitation, abdominal wall reconstruction/injury, and in those with space-occupying disorders in the abdomen. Gold standard for diagnosis involves measurement of bladder pressure, with a pressure greater than 12 mm Hg being consistent with IAH and greater than 25 mm Hg being consistent with ACS. Decompressive laparotomy is definitive therapy but paracentesis can be equally therapeutic in properly selected patients. Left untreated, ACS can lead to multisystem organ failure and death.

    The abdominal compartment is separated from the thoracic compartment by the diaphragm. Under normal circumstances, a large portion of the venous return crosses the splanchnic and nonsplanchnic abdominal regions before entering the thorax and the right side of the heart. Mechanical ventilation may affect abdominal venous return independent of its interactions at the thoracic level. Changes in pressure in the intra-abdominal compartment may have important implications for organ function within the thorax, particularly if there is a sustained rise in intra-abdominal pressure. It is important to understand the consequences of abdominal pressure changes on respiratory and circulatory physiology. This article elucidates important abdominal-respiratory-circulatory interactions and their clinical effects. PMID:27016167

    Intra-abdominal hypertension (IAH) is an important contributor to early organ dysfunction in trauma and sepsis. However, relatively little is known about the impact of intra-abdominal pressure (IAP) in general internal medicine, pregnant patients, and those with obesity or burns. The aim of this paper is to review the pathophysiologic implications and treatment options for IAH in these specific situations. A MEDLINE and PubMed search was performed and the resulting body-of-evidence included in the current review on the basis of relevance and scientific merit. There is increasing awareness of the role of IAH in different clinical situations. Specifically, IAH will develop in most (if not all) severely burned patients, and may contribute to early mortality. One should avoid over-resuscitation of these patients with large volumes of fluids, especially crystalloids. Acute elevations in IAP have similar effects in obese patients compared to non-obese patients, but the threshold IAP associated with organ dysfunction may be higher. Chronic elevations in IAP may, in part, be responsible for the pathogenesis of obesity-related co-morbid conditions such as hypertension, pseudotumor cerebri, pulmonary dysfunction, gastroesophageal reflux disease, and abdominal wall hernias. At the bedside, measuring IAP and considering IAH in all critical maternal conditions is essential, especially in preeclampsia/eclampsia where some have hypothesized that IAH may have an additional role. IAH in pregnancy must take into account the precautions for aorto-caval compression and has been associated with ovarian hyperstimulation syndrome. Recently, IAP has been associated with the cardiorenal dilemma and hepatorenal syndrome, and this has led to the recognition of the polycompartment syndrome. In conclusion, IAH and ACS have been associated with several patient populations beyond the classical ICU, surgical, and trauma patients. In all at risk conditions the focus should be on the early

  5. Repeated Exposure to Conditioned Fear Stress Increases Anxiety and Delays Sleep Recovery Following Exposure to an Acute Traumatic Stressor

    Repeated stressor exposure can sensitize physiological responses to novel stressors and facilitate the development of stress-related psychiatric disorders including anxiety. Disruptions in diurnal rhythms of sleep–wake behavior accompany stress-related psychiatric disorders and could contribute to their development. Complex stressors that include fear-eliciting stimuli can be a component of repeated stress experienced by human beings, but whether exposure to repeated fear can prime the development of anxiety and sleep disturbances is unknown. In the current study, adult male F344 rats were exposed to either control conditions or repeated contextual fear conditioning for 22 days followed by exposure to no, mild (10), or severe (100) acute uncontrollable tail shock stress. Exposure to acute stress produced anxiety-like behavior as measured by a reduction in juvenile social exploration and exaggerated shock-elicited freezing in a novel context. Prior exposure to repeated fear enhanced anxiety-like behavior as measured by shock-elicited freezing, but did not alter social exploratory behavior. The potentiation of anxiety produced by prior repeated fear was temporary; exaggerated fear was present 1 day but not 4 days following acute stress. Interestingly, exposure to acute stress reduced rapid eye movement (REM) and non-REM (NREM) sleep during the hours immediately following acute stress. This initial reduction in sleep was followed by robust REM rebound and diurnal rhythm flattening of sleep/wake behavior. Prior repeated fear extended the acute stress-induced REM and NREM sleep loss, impaired REM rebound, and prolonged the flattening of the diurnal rhythm of NREM sleep following acute stressor exposure. These data suggest that impaired recovery of sleep/wake behavior following acute stress could contribute to the mechanisms by which a history of prior repeated stress increases vulnerability to subsequent novel stressors and stress-related disorders.

    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.

    Abdominal pain in the elderly can be a challenging and difficult condition to diagnose and treat. The geriatric population has significant comorbidities and often takes polypharmacy that can mask symptoms. The presentation of common conditions can be different than that in the younger population, often lacking the traditional indicators of disease, making it of pivotal importance for the clinician to consider a wide differential during their workup. It is also important to consider extra-abdominal abnormality that may manifest as abdominal pain. PMID:27133249

    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.

    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

    Five years of the annual Health Interview Survey, conducted by the National Center for Health Statistics, are used to estimate the effects of air pollution, smoking, and environmental tobacco smoke on respiratory restrictions in activity for adults, and bed disability for children. After adjusting for several socioeconomic factors, the multiple regression estimates indicate that an independent and statistically significant association exists between these three forms of air pollution and respiratory morbidity. The comparative risks of these exposures are computed and the plausibility of the relative risks is examined by comparing the equivalent doses with actual measurements of exposure taken in the homes of smokers. The results indicate that: (1) smokers will have a 55-75% excess in days with respiratory conditions severe enough to cause reductions in normal activity; (2) a 1 microgram increase in fine particulate matter air pollution is associated with a 3% excess in acute respiratory disease; and (3) a pack-a-day smoker will increase respiratory restricted days for a nonsmoking spouse by 20% and increase the number of bed disability days for young children living in the household by 20%. The results also indicate that the estimates of the effects of secondhand smoking on children are improved when the mother's work status is known and incorporated into the exposure estimate.

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

    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

    The purpose of this study was to examine (a) the acute change in bat velocity (BV) following three types of warm-up procedures for baseball hitting (experiment 1), and (b) the effect of an 8-week training program of isometric contraction conditioning (ISO) on BV (experiment 2). In experiment 1, the BV of 24 collegiate baseball players was measured before and after one of the three warm-up procedures; five standard bat (mass = 850.5 g) dry swings (SBS), five weighted bat (mass = 850.5 g + 680.4 g) dry swings (WBS), and four sets of 5-second maximal voluntary isometric contractions mimicking the bat swing movement pattern (ISO). BV was measured just before ball-bat impact. Experiment 2 followed experiment 1 and used only the ISO warm-up. Twelve of the 24 subjects formed the experimental group and underwent an 8-week training program (3 days per week) of ISO training. Results of experiment 1 indicated (a) no significant change in post-SBS BV (-0.33 m·s-¹), (b) a significant decrease in post-WBS BV (-0.89 m·s-¹; p < 0.05), and (c) a significant increase in post-ISO BV (+0.39 m·s-¹; p < 0.05). In experiment 2, there was a significant increase in baseline BV after the 8-week training period (30.21 ± 1.83 m·s -¹ to 31.15 ± 1.57 m·s-¹). A comparison of BV before and after ISO warm-up revealed that change was significantly greater after the training period (100.17 ± 3.18% vs. 103.75 ± 1.91%). Our results suggest that warm-up with WBS does not increase BV and that using the ISO has both acute and chronic positive effects on BV as a warm-up procedure to improve BV. PMID:23254491

    Abdominal aortic aneurysm refers to abdominal aortic dilation of 3.0 cm or greater. The main risk factors are age older than 65 years, male sex, and smoking history. Other risk factors include a family history of abdominal aortic aneurysm, coronary artery disease, hypertension, peripheral artery disease, and previous myocardial infarction. Diagnosis may be made by physical examination, an incidental finding on imaging, or ultrasonography. The U.S. Preventive Services Task Force released updated recommendations for abdominal aortic aneurysm screening in 2014. Men 65 to 75 years of age with a history of smoking should undergo one-time screening with ultrasonography based on evidence that screening will improve abdominal aortic aneurysm-related mortality in this population. Men in this age group without a history of smoking may benefit if they have other risk factors (e.g., family history of abdominal aortic aneurysm, other vascular aneurysms, coronary artery disease). There is inconclusive evidence to recommend screening for abdominal aortic aneurysm in women 65 to 75 years of age with a smoking history. Women without a smoking history should not undergo screening because the harms likely outweigh the benefits. Persons who have a stable abdominal aortic aneurysm should undergo regular surveillance or operative intervention depending on aneurysm size. Surgical intervention by open or endovascular repair is the primary option and is typically reserved for aneurysms 5.5 cm in diameter or greater. There are limited options for medical treatment beyond risk factor modification. Ruptured abdominal aortic aneurysm is a medical emergency presenting with hypotension, shooting abdominal or back pain, and a pulsatile abdominal mass. It is associated with high prehospitalization mortality. Emergent surgical intervention is indicated for a rupture but has a high operative mortality rate. PMID:25884861

    19 children were diagnosed with abdominal cysts of different origin in the Surgical Unit of the Department of Pediatrics, Medical University of Pécs, Hungary between 2010 and 2013. The authors discuss the details of representative cases of a parovarial cyst, an intestinal duplication, and an omental cyst with emphasis on the clinical symptoms, diagnostic tools, and surgical interventions. The authors conclude that abdominal cysts often cause mild symptoms only, and they are discovered accidentally by ultrasound imaging performed for other reasons. In some cases, the cyst can cause severe complaints or even acute abdomen requiring emergency surgery. Laporoscopy may be a valuable method both in diagnosis and surgical therapy. Abdominal CT or MRI are not required in the majority of the patients. PMID:26552027

    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.

This 79-year-old man was presented to emergency room with acute abdominal pain and an acute lower limb ischemia. Computed tomography scan showed an acute type B aortic dissection feeding the aneurysmal sac of the EVAR. The aneurysm rupture occurred during imaging. Type B aortic dissection is a rare cause of aneurysmal rupture after EVAR. The first postoperative computed tomography scan should maybe include the arch and the descending thoracic aorta to rule out an iatrogenic dissection after EVAR. PMID:26902937

    Recent technological advances in the diagnosis and therapy of abdominal aortic aneurysm and renovascular disease are continuing to bring about changes in the way patients suffering from these conditions are treated. The prevalence of both these conditions is increasing. This is due to greater life-expectancy in patients with arteriosclerosis, a pathogenetic factor underlying both conditions. The application of diagnostic imaging techniques to non-vascular conditions has led to the early diagnosis of abdominal aortic aneurysm. Clinical suspicion of reno-vascular disease can be confirmed easily using high-resolution diagnostic imaging modalities such as CT angiography and magnetic resonance angiography. Endovascular intervention is successfully replacing conventional surgical repair techniques, with the result that it may be possible to improve outcome in both conditions using effective and minimally invasive approaches. Future technological developments will enable these endovascular techniques to be applied in the large majority of patients with abdominal aortic aneurysm or renovascular disease. PMID:17580053

    An intra-abdominal hypertension (IAH) defined as a pathological increase in intra-abdominal pressure (IAP) is commonly found on ICU admission or during the ICU stay. Several studies confirmed that an IAH is an independent predictor for mortality of critically ill patients. The abdominal compartment syndrome (ACS) which is defined as a sustained IAP>20 mmHg (with or without an abdominal perfusion pressure [APP]<60mmHg) that is associated with new organ dysfunction or failure has a mortality of up to 60%. In general, an IAH may be induced by several intra-abdominal as well as extra-abdominal conditions. Reduced abdominal wall compliance, intra-abdominal pathologies (either of the peritoneal space or parenchymateous organs) may lead to an IAH. Most commonly, intra-abdominal infections and/or sepsis and severe trauma or burns are predisposing for an IAH. An early sign may be a decrease in urinary output. The effects of an increased IAP on cardiovascular function are well recognized and include negative effects on preload, afterload and contractility. However, all other compartments of the body may be affected by an IAH. Thus, by an increase of the respective compartment pressure, e.g. intracranial pressure, a poly-compartment syndrome may result. Adequate prevention, a forward-looking strategy, and objective techniques for measurement of IAP are required to avoid or early detect an IAH or ACS. Finally, an immediate and consequent interdisciplinary management using conservative, interventional and operative options are necessary to solve an IAH or ACS. PMID:26863642

    Outcome of children with acute lymphoblastic leukemia (ALL) has improved over the years, but not for those with multiple recurrences because of high therapy resistance and heavily pretreated history that potentially cause physical damages. We describe the case of an 11-year-old boy with a third relapse of ALL and a history of 2 allogeneic bone marrow transplantations. He was successfully treated with clofarabine combination chemotherapy and achieved a fourth remission at 16 months following haploidentical bone marrow transplantation with conditioning regimen of clofarabine and busulfan. Clofarabine/busulfan conditioning might be a preferable option for children with multiple recurrent ALL, and warrants further investigation. PMID:26523380

    We report a case of acute chylous ascites formation presenting as peritonitis (acute chylous peritonitis) in a patient suffering from acute pancreatitis due to hypertriglyceridemia and alcohol abuse. The development of chylous ascites is usually a chronic process mostly involving malignancy, trauma or surgery, and symptoms arise as a result of progressive abdominal distention. However, when accumulation of "chyle" occurs rapidly, the patient may present with signs of peritonitis. Preoperative diagnosis is difficult since the clinical picture usually suggests hollow organ perforation, appendicitis or visceral ischemia. Less than 100 cases of acute chylous peritonitis have been reported. Pancreatitis is a rare cause of chyloperitoneum and in almost all of the cases chylous ascites is discovered some days (or even weeks) after the onset of symptoms of pancreatitis. This is the second case in the literature where the patient presented with acute chylous peritonitis due to acute pancreatitis, and the presence of chyle within the abdominal cavity was discovered simultaneously with the establishment of the diagnosis of pancreatitis. The patient underwent an exploratory laparotomy for suspected perforated duodenal ulcer, since, due to hypertriglyceridemia, serum amylase values appeared within the normal range. Moreover, abdominal computed tomography imaging was not diagnostic for pancreatitis. Following abdominal lavage and drainage, the patient was successfully treated with total parenteral nutrition and octreotide. PMID:22563182

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

    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.

    A functional impairment of the bladder and heart in a decompensated state caused by a pressure overload is accompanied by a decrease in the sarcoplasmic reticulum Ca(2+)-ATPase (SERCA2). The beneficial effects of SERCA2 overexpression in preserving cardiac functions have been previously reported. The aim of the present study was to investigate the effects of overexpressed SERCA2 on bladder functions under physiological and pathological conditions using partial bladder outlet obstruction (BOO) in SERCA2a transgenic Wistar rats (TG). Bladder cystometry and western blot analysis were performed using the wild-type Wistar rats (WT), TG, and BOO models (WTBOO and TGBOO). Persistent overexpression of SERCA2 induces reduced bladder compliance without hypertrophy in TG. BOO induces reduced bladder compliance and hypertrophy in WT and TG in the sub-acute phase, but persistent overexpression of SERCA2a in TG does not aggravate the bladder compliance and hypertrophy. In conclusion, SERCA2a overexpression affects bladder functions under physiological conditions, but not in BOO-induced sub-acute pathological conditions. PMID:24037709

    Ascariasis is the most common helminthic infection in developing countries. It may cause chronic abdominal pain, tenderness and bloating. Our aim is to report a case of acute episodic abdominal pain and pancreatitis associated with ascariasis. We report a 59-year-old female patient who was admitted for acute abdominal pain, having had several previous similar events before one of them was diagnosed as acute idiopathic pancreatitis. On admission, her physical exam was normal. Laboratory results showed hemoglobin 12.2 g/dL, white blood cell count 11 900 cells/mm(3), eosinophils 420 cells/mm(3), serum amylase 84 IU/mL, lipase 22 IU/mL and normal liver function tests. Abdominal ultrasound and a plain abdominal X-ray were also normal. An upper endoscopy showed round white worms in the duodenum and the stomach, some of them with bile in their intestines. The intestinal parasites were diagnosed as Ascaris lumbricoides, and the patient was started on albendazole, with full recovery within a week. We believe that ascariasis should be considered in patients with recurrent abdominal pain and idiopathic pancreatitis. PMID:20447214

    The study evaluated acute impact of tetracycline on the biodegradation of acetate by microbial cultures acclimated to different growth conditions. Two fill/draw reactors were operated to obtain acclimated cultures at sludge ages of 2 and 10 days. Acclimated biomass seeding was used in two series of batch experiments. The first run served as control and others were started with tetracycline doses of 100mg/L and 400mg/L. Parallel batch reactors were also operated for oxygen uptake rate (OUR) measurements. Acute impact was evaluated by model calibration of OUR, chemical oxygen demand (COD) and intracellular storage profiles. Exposure to tetracycline did not impair COD removal but induced a shift in acetate utilization toward polyhydroxybutyrate (PHB) storage. This shift was more pronounced for fast growing biomass; it identified itself both in related process kinetics and the modified stoichiometry between the magnitude of acetate directly used for microbial growth and converted to PHB.

    Cystic fibrosis (CF) is the most common lethal autosomal recessive disease in the white population. Mutation of the CF transmembrane conductance regulator gene on chromosome 7 results in production of abnormally viscous mucus and secretions in the lungs of patients with CF. A similar pathologic process occurs in the gastrointestinal tract, pancreas, and hepatobiliary system. Inspissated mucus causes luminal obstruction and resultant clinical and radiologic complications associated with the disease process. Pancreatic involvement can result in exocrine and endocrine insufficiency, pancreatic atrophy, fatty replacement, or lipomatous pseudohypertrophy. Acute and chronic pancreatitis, pancreatic calcification, cysts, and cystosis also occur. Hepatic manifestations include hepatic steatosis, focal biliary and multilobular cirrhosis, and portal hypertension. Biliary complications include cholelithiasis, microgallbladder, and sclerosing cholangitis. The entire digestive tract can be involved. Distal ileal obstruction syndrome, intussusception, appendicitis, chronic constipation, colonic wall thickening, fibrosing colonopathy, pneumatosis intestinalis, gastroesophageal reflux, and peptic ulcer disease have been described. Renal manifestations include nephrolithiasis and secondary amyloidosis. The educational objectives of this review are to reveal the abdominal manifestations of CF to facilitate focused analysis of cross-sectional imaging in adult patients. Life expectancy in patients with CF continues to improve because of a combination of aggressive antibiotic treatment, improved emphasis on nutrition and physiotherapy, and development of promising new CF transmembrane conductance regulator modulators. As lung function and survival improve, extrapulmonary conditions, including hepatic and gastrointestinal malignancy, will be an increasing cause of morbidity and mortality. Awareness of the expected abdominal manifestations of CF may assist radiologists in identifying

    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. PMID:26365324

    This study investigated varieties and incidence of abnormal physiological conditions in acute schizophrenic patients on emergency. Laboratory data obtained prior to treatment from patients, admitted on an emergency basis during an 18-month period, were evaluated retrospectively, as well as demographics and clinical characteristics. Of 259 male acute schizophrenic patients (ICD-10: F2), 6.9% revealed dehydration, a third had hypokalemia and leukocytosis, and two thirds showed elevated serum muscle enzymes. These percentages were statistically significant compared with those of outpatients. In addition, the former three of these conditions in the F2 group were as frequent as those in alcohol and/or psychoactive substance abusers (ICD-10: F1) on emergency admission, although elevated serum muscle enzymes in the F2 group was less frequent than that in the F1 group. In order to prevent these abnormal physiological conditions from worsening and becoming life-threatening, one fourth of the F2 group [dehydration, 6.9%, severe hypokalemia (< 3.0 mEq/l), 2.3%, and markedly elevated serum muscle enzymes (creatine phosphokinase > 1000 IU/l), 16.5%] required medical management such as fluid therapy and various types of monitoring. In cases of a behavioral emergency, laboratory screening and monitoring of urinary output were essential. Due to their lack of cooperation, case history, physical examination, and initial vital signs did not contribute to detection of their medical condition. PMID:9810481

  19. A focus on intra-abdominal infections

    PubMed Central

    2010-01-01

    Complicated intra-abdominal infections are an important cause of morbidity and are frequently associated with poor prognosis, particularly in higher risk patients. Well defined evidence-based recommendations for intra-abdominal infections treatment are partially lacking because of the limited number of randomized-controlled trials. Factors consistently associated with poor outcomes in patients with intra-abdominal infections include increased illness severity, failed source control, inadequate empiric antimicrobial therapy and healthcare-acquired infection. Early prognostic evaluation of complicated intra-abdominal infections is important to select high-risk patients for more aggressive therapeutic procedures. The cornerstones in the management of complicated intra-abdominal infections are both source control and antibiotic therapy. The timing and the adequacy of source control are the most important issues in the management of intra-abdominal infections, because inadequate and late control of septic source may have a negative effect on the outcomes. Recent advances in interventional and more aggressive techniques could significantly decrease the morbidity and mortality of physiologically severe complicated intra-abdominal infections, even if these are still being debated and are yet not validated by limited prospective trials. Empiric antimicrobial therapy is nevertheless important in the overall management of intra-abdominal infections. Inappropriate antibiotic therapy may result in poor patient outcomes and in the appearance of bacterial resistance. Antimicrobial management is generally standardised and many regimens, either with monotherapy or combination therapy, have proven their efficacy. Routine coverage especially against Enterococci and candida spp is not always recommended, but can be useful in particular clinical conditions. A de escalation approach may be recommended in patients with specific risk factors for multidrug resistant infections such as

    Abdominal aortic aneurysm (AAA) is a condition whereby the terminal aorta permanently dilates to dangerous proportions, risking rupture. The biomechanics of AAA has been studied with great interest since aneurysm rupture is a mechanical failure of the degenerated aortic wall and is a significant cause of death in developed countries. In this review article, the importance of considering the biomechanics of AAA is discussed, and then the history and the state-of-the-art of this field is reviewed - including investigations into the biomechanical behavior of AAA tissues, modeling AAA wall stress and factors which influence it, and the potential clinical utility of these estimates in predicting AAA rupture.

    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

    Surfactant depletion is most often used to study acute respiratory failure in animal models. Because model stability is often criticized, the authors tested the following hypotheses: Repeated pulmonary lavage with normal saline provides stable experimental conditions for 24 hours with a PaO2/FiO2 ratio < 300 mm Hg. Lung injury was induced by bilateral pulmonary lavages in 8 female pigs (51.5 +/- 4.8 kg). The animals were ventilated for 24 hours (PEEP: 5 cm H2O; tidal volume: 6 mL/kg; respiratory rate: 30/min). After 24 hours the animals were euthanized. For histopathology slides from all pulmonary lobes were obtained. Supernatant of the bronchoalveolar fluid collected before induction of acute respiratory distress syndrome (ARDS) and after 24 hours was analyzed. A total of 19 +/- 6 lavages were needed to induce ARDS. PaO2/FiO2 ratio and pulmonary shunt fraction remained significantly deteriorated compared to baseline values after 24 hours (P < .01). Slight to moderate histopathologic changes were detected. Significant increases of tumor necrosis factor (TNF)-alpha, interleukin (IL)-1beta, and IL-6 were observed after 24 hours (P < .01). The presented surfactant depletion-based lung injury model was associated with increased pulmonary inflammation and fulfilled the criteria of acute ling injury (ALI) for 24 hours. PMID:19337905

The results demonstrate that changes in the amount of cloudiness and air temperature are the most representative weather predictors among the studied parameters. A discrimination surface was developed for the prediction of AAD events 6 h ahead, and it is found that, under a specific amount of cloudiness and air temperature, the risk of AAD events in Berlin increases about 20 %.

    Dual energy scanned projection radiography of the abdomen has been performed using an experimental line-scanned radiographic system. Digital images simultaneously obtained at 85 and 135 kVp are combined, using photoelectric/Compton decomposition algorithms to create images from which selected materials are cancelled. Soft tissue cancellation images have proved most useful in various abdominal imaging applications, largely due to the elimination of obscuring high-contrast bowel gas shadows. These techniques have been successfully applied to intravenous pyelography, oral cholecystography, intravenous abdominal arteriog-raphy and the imaging of renal calculi.

    Abdominal vascular catastrophes are among the most challenging and time sensitive for emergency practitioners to recognize. Mesenteric ischemia remains a highly lethal entity for which the history and physical examination can be misleading. Laboratory tests are often unhelpful, and appropriate imaging must be quickly obtained. A multidisciplinary approach is required to have a positive impact on mortality rates. Ruptured abdominal aortic aneurysm likewise may present in a cryptic fashion. A specific type of ruptured aneurysm, the aortoenteric fistula, often masquerades as the more common routine gastrointestinal bleed. The astute clinician recognizes that this is a more lethal variant of gastrointestinal hemorrhage. PMID:27133247

    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. PMID:26450606

    Patient satisfaction is a complex construct and is regarded as an important component in the assessment of care quality. Investigations into patient satisfaction with care have steadily increased across a range of specialties over the last three decades, but there has been a paucity of studies into satisfaction with physiotherapy. The limitations of previous instruments used to examine satisfaction with outpatient (OP) physiotherapy suggested the need for a new tool. The aim of the survey was to examine the level of satisfaction that patients with acute and chronic musculoskeletal conditions have with their physiotherapy outpatient treatment within the NHS system of care in the UK. Questionnaires were mailed to 420 patients with acute and chronic musculoskeletal conditions who had recently completed a course of OP physiotherapy. The 38-item self-completion questionnaire comprised six subscales; Expectation, Communication, Therapist, Organisation, Outcome, and Satisfaction, scored on a five-point Likert scale. Data were analysed by using SPSS Release 10 for Windows for frequency distribution of scores and regression analysis for factors predictive of satisfaction. The response rate was 66%. Results showed that patients were generally satisfied with the interpersonal, technical, and organisational aspects of care, although there was lower satisfaction with the clinical outcome in both groups. Organisational issues were the key determinants of satisfaction for the whole sample and the chronic group, with the therapist as key determinant for the acute group. Patient satisfaction surveys conducted as part of a continuous quality improvement programme are particularly important in providing therapists with feedback from patients about their experiences of physiotherapy services. This study has successfully used a new questionnaire to examine patients' satisfaction with outpatient physiotherapy in the United Kingdom. Further studies are now needed to validate the new

    The effective diuretic dose of 5-HT3 receptor blocker RU-63 (1 mg/kg) was found in experiments on white rats. It is established that the diuretic and saluretic effects of compound RU-63 increase on the background of impact of the gravitational factor. Compound RU-63 (1 mg/kg, subcutaneously) administered daily under hypergravity conditions (3 g in the direction of centrifugal force toward the kidneys) in animals with model ischemic acute renal failure increased excretory function of kidneys, glomerular filtration rate, and creatininuresis (on average by 180%; p < 0.05), and decreased serum creatinine, urinary excretion of protein, lactate dehydrogenase, and g-glutamyl transferase (on average by 49%; p < 0.05) as compared to the untreated control. Under similar conditions, the diuretic hydrochlorothiazide (in a dose of 20 mg/kg, intragastric) produced a more pronounced creatininuretic action than that of RU-63 (by 358%; p < 0.05).

    PubMed

    Sawchuck, Diane J; Wittmann, Bernd K

    2014-11-01

    This hypothesis proposes pre-eclampsia is caused by intra-abdominal hypertension in pregnancy. Sustained or increasing intra-abdominal pressure ⩾12mmHg causes impaired venous return to the heart, systemic vascular resistance, ischemia reperfusion injury, intestinal permeability, translocation of lipopolysaccharide endotoxin to the liver, cytotoxic immune response, systemic inflammatory response, pressure transmission to thoracic and intra-cranial compartments, and multi-organ dysfunction. This hypothesis is predicated on Pascal's law, evidence founded in the intra-abdominal hypertension literature, and the adapted equation ΔIAP-P=ΔIAVF/Cab, where ΔIAP-P=change in intra-abdominal pressure in pregnancy, ΔIAVF=change in intra-abdominal vector force (volume and force direction) and Cab=abdominal compliance. Factors causing increased intra-abdominal pressure in pregnancy include: progressive uterine expansion, obstetrical factors that increase intra-uterine volume excessively or acutely, maternal anthropometric measurements that affect intra-abdominal pressure thresholds, maternal postures that increase abdominal force direction, abdominal compliance that is decreased, diminished with advancing gestation, or has reached maximum expansion, habitation at high altitude, and rapid drops in barometric pressure. We postulate that the threshold for lipopolysaccharide translocation depends on the magnitude of intra-abdominal pressure, the intestinal microbiome complex, and the degree of intestinal permeability. We advance that delivery cures pre-eclampsia through the mechanism of abdominal decompression. PMID:25189485

    Acute abdomen can be defined as a medical emergency in which there is sudden and severe pain in abdomen with accompanying signs and symptoms that focus on an abdominal involvement. It accounts for about 8 % of all children attending the emergency department. The goal of emergency management is to identify and treat any life-threatening medical or surgical disease condition and relief from pain. In mild cases often the cause is gastritis or gastroenteritis, colic, constipation, pharyngo-tonsilitis, viral syndromes or acute febrile illnesses. The common surgical causes are malrotation and Volvulus (in early infancy), intussusception, acute appendicitis, and typhoid and ischemic enteritis with perforation. Lower lobe pneumonia, diabetic ketoacidosis and acute porphyria should be considered in patients with moderate-severe pain with little localizing findings in abdomen. The approach to management in ED should include, in order of priority, a rapid cardiopulmonary assessment to ensure hemodynamic stability, focused history and examination, surgical consult and radiologic examination to exclude life threatening surgical conditions, pain relief and specific diagnosis. In a sick patient the initial steps include rapid IV access and normal saline 20 ml/kg (in the presence of shock/hypovolemia), adequate analgesia, nothing per oral/IV fluids, Ryle's tube aspiration and surgical consultation. An ultrasound abdomen is the first investigation in almost all cases with moderate and severe pain with localizing abdominal findings. In patients with significant abdominal trauma or features of pancreatitis, a Contrast enhanced computerized tomography (CECT) abdomen will be a better initial modality. Continuous monitoring and repeated physical examinations should be done in all cases. Specific management varies according to the specific etiology. PMID:23456644

    A review of all cases of abdominal aortic aneurysm presenting to Addenbrooke's Hospital, Cambridge, in a 4-year period revealed that there were 118 such patients and confirmed the relatively low operative mortality for elective aneurysmal surgery (6.6%) compared with the high mortality (66.6%) for ruptured or leaking abdominal aneurysm. In only 50% of the cases was the correct diagnosis made during the lifetime of the patient; nor was the correct diagnosis always made after admission to hospital. The need for an early and accurate diagnosis of abdominal aneurysms is stressed and an increased awareness of this condition, based on well established clinical features, would undoubtedly reduce the overall mortality.

    Brain functions are known to consume high levels of energy, thus, the integrity of cognitive performance can be drastically impacted by acute caloric restriction. In this study, we tested the impact of a 40% caloric restriction on the cognitive abilities of the grey mouse lemur (Microcebus murinus). Twenty-three male mouse lemurs were divided into two groups: 13 control animals (CTL) that were fed with 105kJ/day and 10calorie restricted (CR) animals that received 40% less food (63kJ/day) than the CTL animals. The animals were fed according to their group for 19days. Before treatment, we assessed baseline associative learning capacities, resting metabolic rates and locomotor performance of both animal groups. After treatment, we tested the same functions as well as long-term memory. Our results showed that CR animals had lower learning performance following caloric restriction. The effects of caloric restriction on memory recall varied and depended on the metabolism of the individual animal. Body mass loss was linked to memory test performance in the CR group, and lower performance was observed in individuals losing the most weight. While CR was observed to negatively impact learning, locomotor capacities were preserved in CR animals, and there were higher resting metabolic rates in the CR group. Our data reinforce the strong link between energy allocation and brain function, and suggest that in the context of food shortage, learning capacities could be a limiting parameter in the adaptation to a changing environment.

    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. PMID:27096295

    Component separation is established for complex hernia repairs. This case presents early component separation and release of the anterior and posterior sheath to facilitate closure of the abdominal wall following emergency laparotomy, reinforcing the repair with a biological mesh. On Day 11 following an emergency laparotomy for penetrating trauma, this patient underwent component separation and release of the anterior and posterior sheath. An intra-abdominal biological mesh was secured, and the fascia and skin closed successfully. Primary abdominal closure can be achieved in patients with penetrating abdominal trauma with the use of component separation and insertion of intra-abdominal biological mesh, where standard closure is not possible.

    This study was undertaken to identify subgroups of the population susceptible to the effects of ambient air particles. Fixed-site air pollution monitors in Montreal, Quebec, Canada, provided daily mean levels of various measures of particulates and gaseous pollutants. Total sulfates were also measured daily (1986-1993) at a monitoring station 150 km southeast of the city (Sutton, Quebec, Canada). We used coefficient of haze (COH), extinction coefficient, and Sutton sulfates to predict fine particles and sulfates from a fine particles model for days that were missing. We used the universal Quebec medicare system to obtain billings and prescriptions for each Montreal resident who died in the city from 1984 to 1993. These data were then used to define cardiovascular and respiratory conditions that subjects had before death. Using standard Poisson regression time-series analyses, we estimated the association between daily nonaccidental mortality and daily concentrations of particles in the ambient air among persons with cardiovascular and respiratory conditions diagnosed before death. We found no persuasive evidence that daily mortality increased when ambient air particles were elevated for subgroups of persons with chronic upper respiratory diseases, airways disease, cerebrovascular diseases, acute coronary artery disease, and hypertension. However, we found that daily mortality increased linearly as concentrations of particles increased for persons who had acute lower respiratory diseases, chronic coronary artery diseases (especially in the elderly), and congestive heart failure. For this latter set of conditions, the mean percent increase in daily mortality (MPC) for an increase in the COH across its interquartile range (18.5 COH units per 327.8 linear meters), averaged over the day of death and the 2 preceding days, was MPC = 5.09% [95% confidence interval (CI) 2.47-7.79%], MPC = 2.62 (95% CI 0.53-4.75%), and MPC = 4.99 (95% CI 2.44-7.60%), respectively

    Tetrabromobisphenol A (TBBPA) is a well-known brominated flame retardant. It has been detected in the environment and shows high acute toxicity to different organisms at high concentrations. In this work, the effects of pH and dimethyl sulfoxide (DMSO) on the acute toxicity of TBBPA to Daphnia magna and Limnodrilus hoffmeisteri were tested, and the oxidative stress induced by TBBPA in livers of Carassius auratus was assessed using four biomarkers. The integrated biomarker response (IBR) was applied to assess the overall antioxidant status in fish livers. Moreover, fish tissues (gills and livers) were also studied histologically. The results showed that low pH and DMSO enhanced the toxicity of TBBPA. Furthermore, changes in the activity of antioxidant enzymes and glutathione level suggested that TBBPA generates oxidative stress in fish livers. The IBR index revealed that fish exposed to 3mg/L TBBPA experienced more serious oxidative stress than exposed to acidic or alkaline conditions. The histopathological analysis revealed lesions caused by TBBPA. This study provides valuable toxicological information of TBBPA and will facilitate a deeper understanding on its potential toxicity in realistic aquatic environments. PMID:25980965

    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. PMID:26802564

    OBJECTIVE: To investigate comorbid conditions with prognostic influence in non–ST-segment elevation acute coronary syndrome (NSTEACS). PATIENTS AND METHODS: The study group consisted of a derivation cohort of 1017 patients (admitted from October 1, 2002, through October 1, 2008) and an external validation cohort of 652 patients (admitted from February 1, 2006, through September 30, 2009). Comorbid conditions, including risk factors and components of the Charlson comorbidity index (ChCI) and coronary artery disease–specific index, were recorded. The main outcome was one-year mortality. RESULTS: During follow-up, 103 patients died. After adjusting for variables associated with NSTEACS characteristics (base model), 5 comorbid conditions predicted mortality: severe or mild renal failure (hazard ratio [HR], 2.9 and HR, 1.6, respectively), dementia (HR, 3.1), peripheral artery disease (HR, 2.0), previous heart failure (HR, 2.6), and previous myocardial infarction (HR, 1.4). A simple comorbidity index (SCI) was developed using these variables, (per point: HR, 1.6; 95% confidence interval, 1.4-1.8; P=.0001). Adding the SCI, Charlson comorbidity index, or coronary artery disease–specific index to the base model resulted in a gain of 6.58%, 5.00%, and 4.04%, respectively, in discriminative ability (P=.001), without significant differences among the 3 indices. In patients with comorbid conditions, the highest risk period was in the first weeks after NSTEACS. The strength of the association between SCI and mortality rate was similar in the external validation cohort (HR, 1.3; 95% confidence interval, 1.1-1.6; P=.001). CONCLUSION: Renal dysfunction, dementia, peripheral artery disease, previous heart failure, and previous myocardial infarction are the comorbid conditions that predict mortality in NSTEACS. A simple index using these variables proved to be as accurate as the more complex comorbidity indices for risk stratification. In-hospital management of patients with

    The reproduction of many species is determined by seasonally-driven resource supply. But it is difficult to quantify whether the fecundity is sensitive to short- or long-term exposure to environmental conditions such as rainfall that drive resource supply. Using 25 years of data on individual fecundity of European female rabbits, Oryctolagus cuniculus, from semiarid Australia, we investigate the role of individual body condition, rainfall and temperature as drivers of seasonal and long-term and population-level changes in fecundity (breeding probability, ovulation rate, embryo survival). We built distributed lag models in a hierarchical Bayesian framework to account for both immediate and time-lagged effects of climate and other environmental drivers, and possible shifts in reproduction over consecutive seasons. We show that rainfall during summer, when rabbits typically breed only rarely, increased breeding probability immediately and with time lags of up to 10 weeks. However, an earlier onset of the yearly breeding period did not result in more overall reproductive output. Better body condition was associated with an earlier onset of breeding and higher embryo survival. Breeding probability in the main breeding season declined with increased breeding activity in the preceding season and only individuals in good body condition were able to breed late in the season. Higher temperatures reduce breeding success across seasons. We conclude that a better understanding of seasonal dynamics and plasticity (and their interplay) in reproduction will provide crucial insights into how lagomorphs are likely to respond and potentially adapt to the influence of future climate and other environmental change.

    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

    The aim of this study was to review the literature regarding the rupture of hydatid cysts into the abdominal cavity after trauma. We present both a new case of hydatid cyst rupture that occurred after blunt abdominal trauma and a literature review of studies published in the English language about hydatid cyst rupture after trauma; studies were accessed from PubMed, Google Scholar, EBSCO, EMBASE, and MEDLINE databases. We identified 22 articles published between 2000 and 2011 about hydatid cyst rupture after trauma. Of these, 5 articles were excluded because of insufficient data, duplication, or absence of intra-abdominal dissemination. The other 17 studies included 68 patients (38 males and 30 females) aged 8 to 76 years who had a ruptured hydatid cyst detected after trauma. The most common trauma included traffic accidents and falls. Despite optimal surgical and antihelmintic therapy, 7 patients developed recurrence. Complications included biliary fistula in 5 patients, incisional hernia in 2 patients, and gastrocutaneous fistula in 1 patient. Death occurred from intraoperative anaphylactic shock in 1 patient and gastrointestinal bleeding and pulmonary failure in 1 patient. Rupture of a hydatid cyst into the peritoneal cavity is rare and challenging for the surgeon. This condition is included in the differential diagnosis of the acute abdomen in endemic areas, especially in young patients. PMID:23113853

    Neuromyelitis Optica (NMO), previously regarded as a form of multiple sclerosis, is defined by Gault and Devic, as a retrobulbar neuritis or papillitis accompanied by acute myelitis and occasionally other neurological symptom or signs not restricted to the spinal cord or optic nerves. With the diagnosis of specific antibodies, probable role of humoral immunity supports its pathogenesis. Only a few cases of NMO have been reported in association with pulmonary tuberculosis (TB). Here we report a case of young girl with acute onset paraplegia diagnosed to have NMO, who later on during hospital stay developed ascites which cultured positive for Mycobacterium tuberculosis. This association of abdominal TB with NMO is under-reported in literature. PMID:26522188

    Neprilysin (NEP) is a key cell surface peptidase in the maintenance of airway homeostasis and the development of pulmonary disorders. However, little information is available about the effect of particulate matter (PM) on airway NEP. In this controlled human exposure study, changes in induced sputum were measured in eleven subjects at baseline, overshot (OS) mucking, and diesel exhaust (DE) exposure days. Neither OS condition nor DE exposure was found to induce significant changes in total protein, but DE induced significant increases in cell numbers of macrophages and epithelium. Moreover, significant increases in soluble NEP were observed following OS mining dust particulates (0.43 ± 0.06, p = 0.023) and DE exposure (0.30 ± 0.04, p = 0.035) when compared with the baseline control (0.40 ± 0.03), with 42% and 31% average net increase, respectively. Pearson’s correlation analyses indicated that sputum NEP activity were significantly associated with personal exposure product [Elemental carbon concentration, mg/m3 X time, min. (C X T)]. Data suggest that the changes in NEP activity may be an early, accurate endpoint for airway epithelial injury and provided a new insight into the mechanism of the airway effects in these exposure conditions.

    Acute Human Cytomegalovirus (HCMV) infection is an unusual cause of venous thromboembolism, a potentially life-threatening condition. Thrombus formation can occur at the onset of the disease or later during the recovery and may also occur in the absence of acute HCMV hepatitis. It is likely due to both vascular endothelium damage caused by HCMV and impairment of the clotting balance caused by the virus itself. Here we report on two immunocompetent women with splanchnic thrombosis that occurred during the course of acute HCMV infection. Although the prevalence of venous thrombosis in patients with acute HCMV infection is unknown, physicians should be aware of its occurrence, particularly in immunocompetent patients presenting with fever and unexplained abdominal pain.

    Objective To investigate the performance of monaural and binaural beamforming technology with an additional noise reduction algorithm, in cochlear implant recipients. Method This experimental study was conducted as a single subject repeated measures design within a large German cochlear implant centre. Twelve experienced users of an Advanced Bionics HiRes90K or CII implant with a Harmony speech processor were enrolled. The cochlear implant processor of each subject was connected to one of two bilaterally placed state-of-the-art hearing aids (Phonak Ambra) providing three alternative directional processing options: an omnidirectional setting, an adaptive monaural beamformer, and a binaural beamformer. A further noise reduction algorithm (ClearVoice) was applied to the signal on the cochlear implant processor itself. The speech signal was presented from 0° and speech shaped noise presented from loudspeakers placed at ±70°, ±135° and 180°. The Oldenburg sentence test was used to determine the signal-to-noise ratio at which subjects scored 50% correct. Results Both the adaptive and binaural beamformer were significantly better than the omnidirectional condition (5.3 dB±1.2 dB and 7.1 dB±1.6 dB (p<0.001) respectively). The best score was achieved with the binaural beamformer in combination with the ClearVoice noise reduction algorithm, with a significant improvement in SRT of 7.9 dB±2.4 dB (p<0.001) over the omnidirectional alone condition. Conclusions The study showed that the binaural beamformer implemented in the Phonak Ambra hearing aid could be used in conjunction with a Harmony speech processor to produce substantial average improvements in SRT of 7.1 dB. The monaural, adaptive beamformer provided an averaged SRT improvement of 5.3 dB. PMID:24755864

    This nine-chapter book gives an overview of the integrated approach to abdominal imaging. Chapter 1 provides an introduction to the physics used in medical imaging; chapter 2 is on the selection of imaging modalities. These are followed by four chapters that deal, respectively, with plain radiography, computed tomographic scanning, sonography, and nuclear imaging, as applied to the abdomen. Two chapters then cover contrast material-enhanced studies of the gastrointestinal (GI) tract: one focusing on technical considerations; the other, on radiologic study of disease processes. The final chapter is a brief account of different interventional procedures.

    Although most frequently presenting with lower abdominal pain, appendicitis, colitis, and diverticulitis can cause pain throughout the abdomen and can cause peritoneal and retroperitoneal symptoms. Evaluation and management of lower intestinal disease requires a nuanced approach by the emergency physician, sometimes requiring computed tomography, ultrasonography, MRI, layered imaging, shared decision making, serial examination, and/or close follow-up. Once a presumed or confirmed diagnosis is made, appropriate treatment is initiated, and may include surgery, antibiotics, and/or steroids. Appendicitis patients should be admitted. Diverticulitis and inflammatory bowel disease can frequently be managed on an outpatient basis, but may require admission and surgical consultation. PMID:27133242

    Abstract We evaluated the acute (up to 24 h) pathophysiological response to primary blast using a rat model and helium driven shock tube. The shock tube generates animal loadings with controlled pure primary blast parameters over a wide range and field-relevant conditions. We studied the biomechanical loading with a set of pressure gauges mounted on the surface of the nose, in the cranial space, and in the thoracic cavity of cadaver rats. Anesthetized rats were exposed to a single blast at precisely controlled five peak overpressures over a wide range (130, 190, 230, 250, and 290 kPa). We observed 0% mortality rates in 130 and 230 kPa groups, and 30%, 24%, and 100% mortality rates in 190, 250, and 290 kPa groups, respectively. The body weight loss was statistically significant in 190 and 250 kPa groups 24 h after exposure. The data analysis showed the magnitude of peak-to-peak amplitude of intracranial pressure (ICP) fluctuations correlates well with mortality rates. The ICP oscillations recorded for 190, 250, and 290 kPa are characterized by higher frequency (10–20 kHz) than in other two groups (7–8 kHz). We noted acute bradycardia and lung hemorrhage in all groups of rats subjected to the blast. We established the onset of both corresponds to 110 kPa peak overpressure. The immunostaining against immunoglobulin G (IgG) of brain sections of rats sacrificed 24-h post-exposure indicated the diffuse blood-brain barrier breakdown in the brain parenchyma. At high blast intensities (peak overpressure of 190 kPa or more), the IgG uptake by neurons was evident, but there was no evidence of neurodegeneration after 24 h post-exposure, as indicated by cupric silver staining. We observed that the acute response as well as mortality is a non-linear function over the peak overpressure and impulse ranges explored in this work. PMID:23362798

    The hypothalamus (HYP) and hippocampus (HIP) are important regions involved in stress responses. These areas are also associated with reward processing. In this study, the effects of acute and subchronic stress on the changes in apoptotic factors (Bax/Bcl-2 ratio, caspase-3 activation and PARP degradation) in the HYP and HIP during conditioned place preference (CPP) paradigm were evaluated. Male Wistar rats were divided into two saline- and morphine-treated supergroups. Each supergroup contained control, acute stress (AS) and subchronic stress (SS) groups. In all groups, CPP paradigm was done and thereinafter alterations of apoptotic factors were measured by western blot. The results revealed that in the HYP, all mentioned factors increased significantly in saline- or morphine-treated animals during AS and SS. On the other hand, in the HIP, Bax/Bcl-2 ratio in saline-treated animals increased significantly during AS and SS, while in morphine-treated animals this ratio did not have any significant alteration during AS and was decreased during SS compared with morphine-control group. Caspase-3 and PARP increased during AS and SS in saline- or morphine-treated animals. For example, caspase-3 increased during AS and SS in morphine-treated animals by 2.4 folds and PARP (89 KDa) increased by 3.1 and 3.5 folds, respectively. Interestingly, the increase of apoptotic factors in morphine-treated animals was more considerable than that of saline-treated animals. These results strongly implied that AS and SS trigger apoptotic events in the HYP and HIP of saline- and/or morphine-treated animals as well as morphine reinforces the effect of stress on the induction of apoptosis.

    While allogeneic hematopoietic cell transplantation (HCT) may offer the best chance of cure for patients suffering from aggressive hematological malignancies such as acute myeloid leukemia, acute lymphoblastic leukemia, and myelodysplastic syndrome, successful outcomes for the subgroup of patients with high-risk disease remain disappointing and lag behind those of lower-risk patients. Because relatively high rates of relapse are an important contributor to these poor outcomes, efforts have explored approaches to increase the cytotoxic effects of treatment. Relapse rates have been shown to improve with the addition of increased doses of total body irradiation (TBI) and/or the introduction of additional chemotherapy to a HCT conditioning regimen. However, the increase in TBI dose and/or additional chemotherapy has also been associated with a significant increase in life-threatening toxicities, resulting in no change in overall survival. Radioimmunotherapy (RIT) has been employed as an adjunct to HCT where targeted delivery of radiation may allow for further escalation of therapy to reduce relapse with minimal toxicity. In this review we describe these efforts, including the benefits of escalating the dose of radiation to sites of hematologic disease prior to HCT, the various cellular targets for antibody-mediated delivery of radiation, as well as the rationale for incorporation of various radionuclides such as alpha emitters and beta emitters into the preparative regimen prior to HCT. Lastly, newer novel approaches such as pretargeted RIT (PRIT) are described as a method to further increase delivery of targeted radiation to hematological tissues while sparing noninvolved organs.

    Conditioning-related gut toxicity can result in a protein-losing enteropathy manifesting as a decline in serum albumin in the peritransplant period. Inspired by the pathogenesis of acute graft-versus-host disease (aGVHD), we hypothesized that the magnitude of decline in serum albumin from the day of conditioning initiation until its nadir in the first 2 weeks after hematopoietic cell transplantation HCT (DeltaAlb) predicts the risk for subsequent severe aGVHD. We reviewed the medical records of all 88 patients with acute myeloid leukemia or myelodysplastic syndrome who underwent highly mucotoxic myeloablative (busulfan/cyclophosphamide or cyclophosphamide/total body irradiation) allogeneic HCT from a matched related donor (MRD) or matched unrelated donor (MUD) at our institution between January 1, 2012 and January 1, 2015. Severe aGVHD was associated with MUD (47% versus 14% with MRD; P = .001) and DeltaAlb, which was significantly greater among patients who developed versus did not develop severe aGVHD (1.2 ± .5 versus .8 ± .4 g/dL, respectively; P < .001). In multivariate analysis DeltaAlb remained a significant predictor of severe aGVHD (odds ratio, 5.68; 95% CI, 1.65 to 19.64; P = .006; area under the ROC curve, .74; 95% CI, .63 to .86; P < .001). The best cutoff for DeltaAlb to predict severe aGVHD was .9, with a sensitivity, specificity, and overall classification accuracy of 77%, 66%, and 69%, respectively. The model was validated using the bootstrap technique, with no significant change in its performance. These results were not generalizable to a cohort of 30 patients who received less mucotoxic myeloablative or reduced-intensity conditioning. In conclusion, with mucotoxic myeloablative HCT, each .1-g/dL increase in DeltaAlb was associated with an approximately 23% increase in the odds of developing severe aGVHD. As an early biomarker of gut damage, DeltaAlb can be incorporated in composite risk models for aGVHD prediction, with hopes for

    Objectives. Overview the quality, direction, and characteristics of yoga interventions for treatment of acute and chronic health conditions in adult populations. Methods. 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. PMID:23762174

    Early management of rapid massive hemorrhage requires early administration of blood products and rapid surgical control of bleeding. Professionals in peripheral hospitals with limited resources often work under conditions similar to those in the military. Described in the present report are 3 cases in which warm fresh whole blood (WFWB) was used in patients with massive bleeding who presented to a peripheral hospital that had no blood products suitable for emergency conditions. Described first is the case of a 16-year-old female patient who underwent emergency cesarean section. The patient had massive bleeding from the uterus due to atony. Her hemoglobin (Hb) dropped to 3.5 g/dL. Six units of WFWB were transfused during surgery. Hemodynamic parameters and complete blood count (CBC) stabilized. She was transferred from the intensive care unit (ICU) to obstetrics on day 2 and was discharged on day 7. Described second is the case of a 35-year-old female patient who also underwent emergency cesarean section, and for whom massive bleeding was due to uterine atony. Hb dropped to 2 g/dL and hematocrit (HCT) to 5.4%. Nine units of WFWB were transfused, after which hemodynamic and laboratory parameters stabilized. The patient was extubated the following day, transferred from the ICU to obstetrics on day 3, and was discharged on day 8. Described third is the case of a 36-year-old male patient with stab injuries and hemorrhagic shock who underwent emergency surgery. The patient had injuries to the right renal artery and kidney. Nine units of WFWB were transfused due to continued hemorrhage during surgery. Following surgical control of bleeding and transfusion, hemodynamic parameters improved. The patient was transferred from the ICU on day 5 and discharged on day 10. WFWB transfusion nearly disappeared from civilian medicine after blood was separated into components, and whole blood is not usually available at blood banks. In massive transfusions, WFWB effectively replaces

    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.

    Chronic abdominal pain is one of the most common clinical syndromes encountered in day to day clinical paediatric practice. Although common, its definition is confusing, predisposing factors are poorly understood and the pathophysiological mechanisms are not clear. The prevailing viewpoint in the pathogenesis involves the inter-relationship between changes in hypersensitivity and altered motility, to which several risk factors have been linked. Making a diagnosis of functional abdominal pain can be a challenge, as it is unclear which further diagnostic tests are necessary to exclude an organic cause. Moreover, large, well-performed, high-quality clinical trials for effective agents are lacking, which undermines evidence-based treatment. This Review summarizes current knowledge regarding the epidemiology, pathophysiology, risk factors and diagnostic work-up of functional abdominal pain. Finally, management options for children with functional abdominal pain are discussed including medications, dietary interventions, probiotics and psychological and complementary therapies, to improve understanding and to maximize the quality of care for children with this condition.

    Patient satisfaction is generally regarded as an important component in quality health care. However, there has been little satisfaction research in physiotherapy compared with that in other clinical fields with few qualitative studies that have explored patients' perceptions and attitudes toward physiotherapy. We report on the use of focus groups, as part of a multimethod approach of qualitative data collection into patients' satisfaction with their outpatient physiotherapy within the NHS system of care in the United Kingdom. We explored the factors that affect patients' satisfaction with musculoskeletal outpatient physiotherapy. A purposeful sample of patients with acute and chronic musculoskeletal patients who had been discharged from physiotherapy within the previous 4 months was drawn from both an inner city and suburban hospital. Two acute groups (n = 4, n = 10) and two chronic groups (n = 5, n = 11) were convened. A topic guide drew on themes that had emerged from the earlier qualitative phases of the study and guided the discussion in relation to pretreatment, treatment, and outcome stages of physiotherapy care. Sessions were tape-recorded, transcribed, and content was analyzed to code and categorise the primary patterns in the data. Although subjects in both the acute and chronic groups expected that treatment would improve their symptoms and function, they differed in the degree to which they perceived that this was achieved. Both satisfactory and unsatisfactory aspects of care emerged under the principal themes of expectations, communication, perceptions of the therapist, treatment process, and outcome. Those in the acute group were optimistic of a good result, whereas those with chronic degenerative conditions were either doubtful of improvement or unrealistic in their hopes for complete resolution of their symptoms. It was also apparent that subjects could be further divided into one of three groups (positive, negative, ambivalent), depending on the

    Summary Background Adult intussusception is a rare phenomenon, acute appendicitis accompanying multiple transient intussusceptions are much more uncommon. Satisfaction and quiting imaging studies after finding an intussusception on ultrasound, may lead diagnostic errors. Radiologists should raise their awareness of imaging findings in intussusception and keep in their mind coexistent troubles in the belly. This unique case presents unusual imaging findings of a rare dual abdominal emergency condition, particularly highlighting the value of abdominal computed tomography. Case Report 32-year-old female was admitted to Emergency Department with complaints of epigastric abdominal pain and vomiting. US identified ‘target’ appereance on left paramedian location at umbilical level. Contrast enhanced abdominal CT not only confirmed the enteric intussusception that was demonstrated on previos US, but also showed additional concomitant intussusceptions and inflamed appendix. Conclusions Adult intussusception is a rare phenomenon, multiple transient intussusceptions are even more uncommon. This unique report adds, precious clinical and imaging findings of acute appendicitis coexisting with multiple spontaneously resolving intussusceptions, to the literature. Physicians should be alerted for accompanying multiple abdominal pathologies and use justification essentials to make their decisions about the selection of the appropriate imaging modality.

    Background Acute bacterial cholangitis for the most part owing to common bile duct stones is common in gastroenterology practice and represents a potentially life-threatening condition often characterized by fever, abdominal pain, and jaundice (Charcot's triad) as well as confusion and septic shock (Reynolds' pentad). Methods This review is based on a systematic literature review in PubMed with the search items ‘cholangitis’, ‘choledocholithiasis’, ‘gallstone disease’, ‘biliary infection’, and ‘biliary sepsis’. Results Although most patients respond to empiric broad-spectrum antibiotic treatment, timely endoscopic biliary drainage depending on the severity of the disease is required to eliminate the underlying obstruction. Specific recommendations have been derived from the Tokyo guideline working group consensus 2006 and its update in 2013, albeit poorly evidence-based, providing a comprehensive overview of diagnosis, classification, risk stratification, and treatment algorithms in acute bacterial cholangitis. Conclusion Prompt clinical recognition and accurate diagnostic workup including adequate laboratory assessment and (aetiology-oriented) imaging are critical steps in the management of cholangitis. Treatment is directed at the two major interrelated pathophysiologic components, i.e. bacterial infection (immediate antimicrobial therapy) and bile duct obstruction (biliary drainage). As for the latter, transpapillary endoscopic drainage by stent or nasobiliary drain and/or same-session bile duct clearance, depending on individual disease severity, represent first-line treatment approaches.

    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. PMID:26655802

    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.

    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

    Acute flank and abdominal pain are common presenting complaints in the emergency department. With increasing access to point-of-care ultrasound (PoCUS), emergency physicians have an added tool to help identify renal problems as a cause of a patient's pain. PoCUS for hydronephrosis has a sensitivity of 72-83.3% and a varying specificity, similar to radiology-performed ultrasonography. In addition to assessment for hydronephrosis, PoCUS can help emergency physicians to exclude other serious causes of flank and abdominal pain such as the presence of an abdominal aortic aneurysm, or free fluid in the intraperitoneal space, which could represent hemorrhage. Use of PoCUS for the assessment of flank pain has resulted in more rapid diagnosis, decreased use of computed tomography, and shorter emergency department length of stay. PMID:27433264

    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

    IMPORTANCE Thousands of physicians attend scientific meetings annually. Although hospital physician staffing and composition may be affected by meetings, patient outcomes and treatment patterns during meeting dates are unknown. OBJECTIVE To analyze mortality and treatment differences among patients admitted with acute cardiovascular conditions during dates of national cardiology meetings compared with nonmeeting dates. DESIGN, SETTING, AND PARTICIPANTS Retrospective analysis of 30-day mortality among Medicare beneficiaries hospitalized with acute myocardial infarction (AMI), heart failure, or cardiac arrest from 2002 through 2011 during dates of 2 national cardiology meetings compared with identical nonmeeting days in the 3 weeks before and after conferences (AMI, 8570 hospitalizations during 82 meeting days and 57 471 during 492 nonmeeting days; heart failure, 19 282 during meeting days and 11 4591 during nonmeeting days; cardiac arrest, 1564 during meeting days and 9580 during nonmeeting days). Multivariable analyses were conducted separately for major teaching hospitals and nonteaching hospitals and for low-and high-risk patients. Differences in treatment utilization were assessed. EXPOSURES Hospitalization during cardiology meeting dates. MAIN OUTCOMES AND MEASURES Thirty-day mortality, procedure rates, charges, length of stay. RESULTS Patient characteristics were similar between meeting and nonmeeting dates. In teaching hospitals, adjusted 30-day mortality was lower among high-risk patients with heart failure or cardiac arrest admitted during meeting vs nonmeeting dates (heart failure, 17.5% [95% CI, 13.7%–21.2%] vs 24.8% [95% CI, 22.9%–26.6%]; P < .001; cardiac arrest, 59.1% [95% CI, 51.4%–66.8%] vs 69.4% [95% CI, 66.2%–72.6%]; P = .01). Adjusted mortality for high-risk AMI in teaching hospitals was similar between meeting and nonmeeting dates (39.2% [95% CI, 31.8%–46.6%] vs 38.5% [95% CI, 35.0%–42.0%]; P = .86), although adjusted percutaneous

    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.

    Abdominal cocoon syndrome (ACS) is a rare cause of intestinal obstruction due to total or partial encapsulation of the small intestine by a fibrocollagenous membrane. Idiopathic ACS with abdominal cryptorchidism and greater omentum hypoplasia is even rarer clinically. We successfully treated a 26-year-old male case of small bowel obstruction with acute peritonitis. He was finally diagnosed with idiopathic ACS with unilateral abdominal cryptorchidism and greater omentum hypoplasia during exploratory laparotomy. He then underwent enterolysis, cryptorchidectomy, and appendectomy. He recovered gradually from the operations and early postoperative inflammatory ileus. There has been no recurrence of intestinal obstruction since the operation, and he is still in follow-up. We analyzed his clinical data and retrospectively reviewed the literature, and our findings may be helpful for the clinical diagnosis and treatment on ACS. PMID:27239122

Idiopathic ACS with abdominal cryptorchidism and greater omentum hypoplasia is even rarer clinically. We successfully treated a 26-year-old male case of small bowel obstruction with acute peritonitis. He was finally diagnosed with idiopathic ACS with unilateral abdominal cryptorchidism and greater omentum hypoplasia during exploratory laparotomy. He then underwent enterolysis, cryptorchidectomy, and appendectomy. He recovered gradually from the operations and early postoperative inflammatory ileus. There has been no recurrence of intestinal obstruction since the operation, and he is still in follow-up. We analyzed his clinical data and retrospectively reviewed the literature, and our findings may be helpful for the clinical diagnosis and treatment on ACS. PMID:27239122

    Acute malocclusion can result from disturbances in the maxillary/mandibular tooth relationship. These alterations in the occlusal position can result from high fillings, sinus problems, abscesses, periodontal disease, and moving or erupting teeth. Conditions seen less frequently include acute malocclusions secondary to an event (such as trauma) that make a stable dental relationship an unstable one. Patients can demonstrate any of a number of clinical conditions that interfere with their comfort and ability to function. This article provides information on some of the less familiar causes of acute malocclusion. PMID:16689064

    Clofarabine has potent antileukemia activity and its inclusion in reduced-intensity conditioning (RIC) allogeneic hematopoietic stem cell transplantation (HSCT) for acute leukemia could potentially improve outcomes. We conducted a phase II study of busulfan (.8 mg/kg i.v. twice daily on days -5, -4, -3, and -2) with clofarabine (40 mg/m(2) i.v. daily on days -5, -4, -3, and -2) conditioning before allogeneic 8/8 HLA-matched related or unrelated HSCT. The primary endpoint was donor neutrophil engraftment by day +40. Secondary endpoints included nonrelapse mortality (NRM), acute and chronic graft-versus-host disease (GVHD), progression-free survival (PFS), and overall survival (OS). Thirty-four patients (acute myeloid leukemia [AML], n = 25; myelodysplastic syndromes, n = 5; and acute lymphoid leukemia, n = 4) were enrolled. Day 40+ engraftment with donor chimerism was achieved in 33 of 34 patients with 1 patient dying before count recovery. Day 100 and 1-year NRM were 5.9% (95% confidence interval [CI], 1.0 to 17.4) and 24% (95% CI, 11 to 39), respectively. The 2-year relapse rate was 26% (95% CI, 13 to 42). Cumulative incidences of acute and chronic GVHD were 21% and 44%, respectively. The 2-year PFS was 50% (95% CI, 32 to 65) and OS was 56% (95% CI, 38 to 71). For patients with AML in first complete remission, 2-year PFS and OS were both 82% (95% CI, 55 to 94). RIC with busulfan and clofarabine leads to successful engraftment with acceptable rates of NRM and GVHD. PMID:26260679

    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 management of patients with penetrating abdominal trauma is outlined in Figure 1. Patients with hemodynamic instability, evisceration, significant gastrointestinal bleeding, peritoneal signs, gunshot wounds with peritoneal violation, and type 2 and 3 shotgun wounds should undergo emergency laparotomy. The initial ED management of these patients includes airway management, monitoring of cardiac rhythm and vital signs, history, physical examination, and placement of intravenous lines. Blood should be obtained for initial hematocrit, type and cross-matching, electrolytes, and an alcohol level or drug screen as needed. Initial resuscitation should utilize crystalloid fluid replacement. If more than 2 liters of crystalloid are needed to stabilize an adult (less in a child), blood should be given. Group O Rh-negative packed red blood cells should be immediately available for a patient in impending arrest or massive hemorrhage. Type-specific blood should be available within 15 minutes. A patient with penetrating thoracic and high abdominal trauma should receive a portable chest x-ray, and a hemo- or pneumothorax should be treated with tube thoracostomy. An unstable patient with clinical signs consistent with a pneumothorax, however, should receive a tube thoracostomy prior to obtaining roentgenographic confirmation. If time permits, a nasogastric tube and Foley catheter should be placed, and the urine evaluated for blood (these procedures can be performed in the operating room). If kidney involvement is suspected because of hematuria or penetrating trauma in the area of a kidney or ureter in a patient requiring surgery, a single-shot IVP should be performed either in the ED or the operating room. An ECG is important in patients with possible cardiac involvement and in patients over the age of 40 going to the operating room. Tetanus status should be updated, and appropriate antibiotics covering bowel flora should be given. Operative management should rarely be delayed

    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.

    Human and animal studies on physiological factors in resistance to acute hypoxia are elaborated. Results show that tolerance of acute hypoxia depends on gas composition and temperature in a sealed cabin, on the length of the stay and motive regime, and on the kind of operator and professional activity. After preliminary adaptation to hypoxia, resistance of the body increases not only to insufficiency of oxygen in inspired air, but also to the effects of other extremum factors of manned space flight.

    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

    The contribution of abdominal aortic aneurysm (AAA) disease to human morbidity and mortality has increased in the aging, industrialized world. In response, extraordinary efforts have been launched to determine the molecular and pathophysiological characteristics of the diseased aorta. This work aims to develop novel diagnostic and therapeutic strategies to limit AAA expansion and, ultimately, rupture. Contributions from multiple research groups have uncovered a complex transcriptional and post-transcriptional regulatory milieu, which is believed to be essential for maintaining aortic vascular homeostasis. Recently, novel small noncoding RNAs, called microRNAs, have been identified as important transcriptional and post-transcriptional inhibitors of gene expression. MicroRNAs are thought to "fine tune" the translational output of their target messenger RNAs (mRNAs) by promoting mRNA degradation or inhibiting translation. With the discovery that microRNAs act as powerful regulators in the context of a wide variety of diseases, it is only logical that microRNAs be thoroughly explored as potential therapeutic entities. This current review summarizes interesting findings regarding the intriguing roles and benefits of microRNA expression modulation during AAA initiation and propagation. These studies utilize disease-relevant murine models, as well as human tissue from patients undergoing surgical aortic aneurysm repair. Furthermore, we critically examine future therapeutic strategies with regard to their clinical and translational feasibility. PMID:23852016

    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. PMID:25398912

    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.

    2016-08-01

    Although abdominal pain is a symptom of several structural gastrointestinal disorders (eg, peptic ulcer disease), this comprehensive review will focus on the 4 most common nonstructural, or functional, disorders associated with abdominal pain: functional dyspepsia, constipation-predominant and diarrhea-predominant irritable bowel syndrome, and functional abdominal pain syndrome. Together, these conditions affect approximately 1 in 4 people in the United States. They are associated with comorbid conditions (eg, fibromyalgia and depression), impaired quality of life, and increased health care utilization. Symptoms are explained by disordered gastrointestinal motility and sensation, which are implicated in various peripheral (eg, postinfectious inflammation and luminal irritants) and/or central (eg, stress and anxiety) factors. These disorders are defined and can generally be diagnosed by symptoms alone. Often prompted by alarm features, selected testing is useful to exclude structural disease. Identifying the specific diagnosis (eg, differentiating between functional abdominal pain and irritable bowel syndrome) and establishing an effective patient-physician relationship are the cornerstones of therapy. Many patients with mild symptoms can be effectively managed with limited tests, sensible dietary modifications, and over-the-counter medications tailored to symptoms. If these measures are not sufficient, pharmacotherapy should be considered for bowel symptoms (constipation or diarrhea) and/or abdominal pain; opioids should not be used. Behavioral and psychological approaches (eg, cognitive behavioral therapy) can be helpful, particularly in patients with chronic abdominal pain who require a multidisciplinary pain management program without opioids.

    Hiatal hernia (HH) is the herniation of elements of the abdominal cavity through the esophageal hiatus of the diaphragm. A giant HH with pancreatic prolapse is very rare and its causing pancreatitis is an even more extraordinary condition. We describe a case of a 65-year-old man diagnosed with acute pancreatitis secondary to pancreatic herniation. In these cases, acute pancreatitis may be caused by the diaphragmatic crura impinging upon the pancreas and leading to repetitive trauma as it crosses the hernia; intermittent folding of the main pancreatic duct; ischemia associated with stretching at its vascular pedicle; or total pancreatic incarceration. Asymptomatic hernia may not require any treatment, while multiple studies have supported the recommendation of early elective repair as a safer route in symptomatic patients. In summary, though rare, pancreatic herniation should be considered as a cause of acute pancreatitis. A high index of suspicion for complications is warranted in cases like these. PMID:27066077

    Aim: To evaluate the role of glutamate receptors in the dorsal hippocampus (DH) in the motivational component of morphine withdrawal. Methods: NMDA receptor antagonist D-AP5 (5 μg/0.5 μL per side) or AMPA receptor antagonist NBQX (2 μg/0.5 μL per side) was microinjected into DH of rats. Conditioned place aversion (CPA) induced by naloxone-precipitated morphine withdrawal were assessed. Results: Preconditioning microinjection of D-AP5 or NBQX into the DH impaired the acquisition of CPA in acute morphine-dependent rats. However, intra-DH microinjection of D-AP5 or NBQX after conditioning but before the testing session had no effect on the expression of CPA. Conclusion: Our results suggest that NMDA and AMPA receptors in the dorsal hippocampus are involved in the acquisition, but not in the expression, of the negative motivational components of acute morphine withdrawal in rats.

    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.

    Urinalysis is a routine and cheap laboratory test that provides clinically useful information in patients with acute abdominal conditions, including acute pancreatitis. The aim of the study was to assess the relationships between the results of urinalysis and the course of the disease among 65 patients with acute pancreatitis (34 men and 31 women, mean age 61 ± 19 years) at the early phase of the disease, i.e. during the first 72 hours from the onset of symptoms. Mild acute pancreatitis was diagnosed in 47 patients, moderately severe in 13 and severe in 5. The most prevalent abnormalities were proteinuria (43% of patients), high urinary bilirubin (20%), erythrocytes (18%), glucose (18%) and leukocytes (17%). High urinary protein and low specific gravity were associated with more severe acute disease and with acute kidney injury. The severity of bilirubinuria and proteinuria were positively correlated with urine concentrations of neutrophil gelatinase associated lipocalin (NGAL). Urinalysis should be routinely performed in patients with acute pancreatitis. PMID:27197429

    Evaluating and "cleaning" of the uterine cavity is probably the most performed operation in women. It is done for several reasons: abortion, evaluation of irregular bleeding in premenopausal period, and postmenopausal bleeding. Abortion is undoubtedly the number one procedure with more than 44 million pregnancies terminated every year. This procedure should not be underestimated and a careful preoperative evaluation is needed. Ideally a sensitive pregnancy test should be done together with an ultrasound in order to confirm a uterine pregnancy, excluding extra-uterine pregnancy, and to detect genital and/or uterine malformations. Three out of four abortions are performed by surgical methods. Surgical methods include a sharp, blunt, and suction curettage. Suction curettage or vacuum aspiration is the preferred method. Despite the fact that it is a relative safe procedure with major complications in less than one percent of cases, it is still responsible for 13% of all maternal deaths. All the figures have not declined in the last decade. Trauma, perforation, and bleeding are a danger triage. When there is a perforation, a laparoscopy should be performed immediately, in order to detect intra-abdominal lacerations and bleeding. The bleeding should be stopped as soon as possible in order to not destabilize the patient. When there is a perforation in the uterus, this "entrance" can be used to perform the curettage. This is particularly useful if there is trauma of the isthmus and uterine wall, and it is difficult to identify the uterine canal. A curettage is a frequent performed procedure, which should not be underestimated. If there is a perforation in the uterus, then this opening can safely be used for vacuum aspiration. PMID:25134300

    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 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. PMID:25943660

    With the introduction of the use of seatbelts in cars, mortality following motor vehicle crashes has decreased significantly. However, two patterns of injuries, the ‘seatbelt sign’ and ‘seatbelt syndrome’ have emerged. Injuries may consist of traumatic abdominal wall disruption. We present two cases of severe abdominal wall disruption caused by a seatbelt injury and treated with primary repair. A review of the literature is provided. Two patients were brought in after a high velocity Motor Vehicle Collision. Both presented with an acute abdomen and a seatbelt sign upon which the decision was made to perform emergency laparotomies. Both patients had an abdominal wall disruption along the seatbelt sign. These disruptions were primarily closed and during six months of follow-up no complications occurred. A disruption of the abdominal wall is a rare complication. However, it is a diagnosis that may not be missed as patients have a higher risk of morbidity and mortality. CT-scanning is an accurate method to detect disruptions. Closure of blunt traumatic abdominal wall disruption can be done primarily with sutures or addition of a mesh. In both cases of the severe abdominal wall disruption, primary repair without mesh in the acute phase was successful. When a laparotomy is not indicated, the abdominal wall must be assessed for disruption. If there is a disruption primary repair is a good option. PMID:27331068

    Macroamylasemia is a condition of persistent, elevated serum amylase activity with no apparent clinical symptoms of a pancreatic disorder. In Korea, however, no such case has been reported to date. We report a case of a 17-year-old female diagnosed with macroamylasemia and acute appendicitis. One day earlier, she developed epigastric and right lower quadrant abdominal pain. She was characterized by high level of serum amylase, but normal lipase. Amylase isoenzyme analysis demonstrated increased fraction of salivary type and follow-up amylase level was persistently increased. Immunofixation disclosed the macroamylase binding with an immunoglobulin, consisting of IgA and kappa chain. The patient was treated by appendectomy, and the abdominal pain subsided. PMID:10642949

    A 43-year-old man, who received total gastrectomy five years ago for advanced gastric cancer, underwent a screening colonoscopy and abdominal CT scan. Abdominal CT scan revealed no abnormal findings. Colonoscopy revealed polyps at the rectum, which were removed by polypectomy. The patient did not complain of abdominal pain or discomfort throughout the procedure. But, he developed right upper quadrant abdominal pain on the next day after colonoscopy. Abdominal CT scan revealed the distended gallbladder with mild wall thickening and suspicious sandy stones or sludge in the gallbladder. The patient underwent an open cholecystectomy. Pathology was compatible with acute cholecystitis. We should be aware of and consider cholecystitis in the differential diagnosis for patients with abdominal pain after colonoscopy. PMID:23354349

    Fifty-eight patients with mild to moderately severe acute pancreatitis were randomly allocated to treatment with or without nasogastric suction (27 and 31 patients respectively). Intravenous fluids and pethidine hydrochloride were also given. The two groups were comparable clinically at the start of the study. There were no differences between the two groups in the mean duration of the following features: abdominal pain or tenderness; absence of bowel movements; raised serum amylase concentration; time to resumption of oral feeding; and days in hospital. Prolonged hyperamylasaemia (serum amylase greater than 0.33 mU/l) occurred in one patient in the suction group and in three patients in the non-suction group. A mild recurrence of abdominal pain after resumption of oral feeding occurred in three patients in the suction group and in two patients in the non-suction group. Two patients in the suction group developed overt consumption coagulopathy and two others pulmonary complications. No patient in the non-suction group had complications. The findings suggest that most patients with mild to moderately severe acute pancreatitis do not benefit from nasogastric suction. The procedure should be elective rather than mandatory in treating this condition. PMID:698650

    PubMed

    Thomas, A; Andrianne, R

    2004-04-01

    The classic presentation of acute renal colic is the sudden onset of very severe pain in the flank primarily caused by the acute ureteral obstruction. The diagnosis is often made on clinical symptoms only, although confirmatory exams are generally performed because many others significant disorders may present with symptom of flank pain that mimics renal colic. Life threatening emergency such as abdominal aortic aneurysm must be ruled out. While non contrast CT has become the standard imaging modality, in some situations, a plain abdominal radiograph associated with a renal ultrasound or a contrast study such as intravenous pyelogram may be preferred. Hematuria is frequently present on urine analysis. The usual therapy represented by analgesic and nonsteroidal anti-inflammatory drugs should be started as soon as possible. Size and location of the stone are the most important predictors of spontaneous passage. Uncontrolled pain by medical therapy, fever, oligo-anuria suggest complicated stone disease. Such conditions require emergency treatment by drainage or stone extraction. Although recurrent stone rate is important, extensive metabolic explorations are not recommended after an uncomplicated first episode. Nevertheless fluid intake is encouraged and a stone chemical analysis should be performed whenever possible. PMID:15182032

    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.

    Two patients developed chylous complications following abdominal aortic aneurysm repair. One patient had chylous ascitis and was successfully treated by a peritoneo-caval shunt. The other patient developed a lymph cyst, which gradually resorbed after puncture. Chylous complications following aortic surgery are rare. Patients in bad a general condition should be treated by initial paracentesis and total parenteral nutrition, supplemented by medium-chain triglyceride and low-fat diet. If no improvement is observed on this regimen, the next step should be implementation of a peritoneo-venous shunt, whereas direct ligation of the leak should be reserved for those who are not responding to this treatment.

    The outcome of patients undergoing HLA-matched unrelated donor allogeneic hematopoietic cell transplantation following reduced-intensity conditioning or myeloablative regimens is reported to be equivalent; however, it is not known if the intensity of the conditioning impacts outcomes after mismatched unrelated donor transplantation for acute myeloid leukemia. Eight hundred and eighty three patients receiving reduced-intensity conditioning were compared with 1041 myeloablative conditioning regimen recipients in the setting of mismatched unrelated donor transplantation. The donor graft was HLA-matched at 9/10 in 872 (83.8%) and at 8/10 in 169 (16.2%) myeloablative conditioning recipients, while in the reduced-intensity conditioning cohort, 754 (85.4%) and 129 (14.6%) were matched at 9/10 and 8/10 loci, respectively. Myeloablative conditioning regimen recipients were younger, 70% being <50 years of age compared to only 30% in the reduced-intensity conditioning group (P=0.0001). Significantly, more patients had secondary acute myeloid leukemia (P=0.04) and Karnofsky Performance Status score <90% (P=0.02) in the reduced-intensity conditioning group. Patients <50 and ≥50 years were analyzed separately. On multivariate analysis and after adjusting for differences between the two groups, reduced-intensity conditioning in patients age ≥50 years was associated with higher overall survival (HR 0.78; P=0.01), leukemia-free survival (HR 0.82; P=0.05), and decreased non-relapse mortality (HR 0.73; P=0.03). Relapse incidence (HR 0.91; P=0.51) and chronic graft-versus-host disease (HR 1.31; P=0.11) were, however, not significantly different. In patients <50 years old, there were no statistically significant differences in overall survival, leukemia-free survival, relapse incidence, non-relapse mortality, and chronic graft-versus-host-disease between the groups.

    When evaluating the abdomen in the emergency setting, CT and ultrasound are the imaging modalities of choice, mainly because of accessibility, speed and lower relative cost. CT has the added benefit of assessing the whole abdomen for a wide spectrum of gastrointestinal disease, whereas ultrasound has the benefit of avoiding ionizing radiation. MRI is another tool that has demonstrated increasing utility in the emergency setting and also avoids the use of ionizing radiation. MRI also has the additional advantage of excellent soft-tissue contrast. However, widespread use of MRI in the emergency setting is limited by availability and relative cost. Despite such limitations, advances in MRI technology, including improved pulse sequences and coil technology and increasing clinician awareness of MRI, have led to an increased demand in abdominal MRI in the emergency setting. This is particularly true in the evaluation of acute pancreatitis; choledocholithiasis with or without cholecystitis; acute appendicitis, particularly in pregnant patients; and, in some cases, Crohn's disease. In cases of pancreatitis and Crohn's disease, MRI also plays a role in subsequent follow-up examinations. PMID:26514590

A retrospective review of 5 children with cancer who had appendicitis while receiving chemotherapy was performed. Case Descriptions: Three had acute lymphoblastic leukemia, and 1 each had T-cell lymphoblastic lymphoma and rhabdomyosarcoma. Two of the patients had a Pediatric Appendectomy Score of 6, and 1 each had a score of 7, 5, and 2. All had evidence of appendicitis on computed tomography. Laparoscopic appendectomy was performed without any perioperative complication. Discussion: Appendicitis is an important diagnosis in children with cancer, and laparoscopic appendectomy is safe and the procedure of choice. PMID:26390529

    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.

    Between July 2000 and June 2003 a total of 21 patients with high-risk acute myeloid leukemia (AML; n = 14), AML after myelodysplastic syndrome (MDS; n = 6) or advanced MDS (n = 1) were treated with an 188-Re labelled anti-CD66 antibody in the conditioning regimen for allogeneic stem cell transplantation. Radioimmunotherapy (RIT) was followed by standard full-dose conditioning with busulfan and high-dose cyclophosphamide in 11 patients and reduced intensity conditioning regimen in 10 patients. All patients received an unmanipulated allogeneic graft from alternative donors (n = 15) or a HLA-identical familiy donor (n = 6). With a median follow up of 42 months (23-60) disease free survival for all patients was 43%. Nine patients are still alive and in ongoing complete hematological remission. The treatment related mortality was 28.6% (n = 6) and an equal number of patients died of relapsing disease within 30-385 days after transplantation. Late organ toxicity, monitored for more than 1 year, was mild and not clinically relevant. The combination of RIT with chemotherapeutic conditioning seems to be a therapy with an acceptable risk of treatment related morbidity and mortality as well as occurrence of severe acute GvHD.

    Malignant schwannoma of the anterior abdominal wall nerves is extremely rare. Malignant peripheral nerve sheath tumors (MPNST) represent approximately 10% of all soft tissue sarcomas and it is found in 4% of patients with neurofibromatosis 1. We present a case of malignant schwannoma in a 28-year-old female patient with neurofibromatosis 1. She presented with a painful mass in the right upper quadrant of her abdomen. The tumor location was in the abdominal wall in explorative laparatomy and malignant schwannoma was diagnosed in pathologic assessment. The tumor recurred in 3 months and computed tomography showed two masses in the right side of abdominopelvic cavity. Thereafter, second complete surgical resection was performed and pathologic finding was the same. In spite of administering chemotherapy after second surgery,the tumor recurred and magnetic resonance imaging finding showed a huge heterogeneously enhancing mass with adhesion to the inner side of the abdominal wall. The patient died because of acute respiratory failure due to multiple bilateral pulmonary metastases. Tumor location and rapid recurrence was unique in our patient.

    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

    Malrotation in children is due to either an incomplete or non-rotation of the foetal mid-gut during perinatal development. Presentation is usually in the first few weeks of life, often with life-threatening volvulus and ischaemia. However, it can be a rare cause of abdominal pain in older children and young adults. We present such a case, as a reminder to emergency physicians that malrotation should be considered in the differential diagnosis of recurrent or chronic abdominal pain not only in children but also in adolescents.

    Although the case fatality rate for ectopic pregnancies has decreased to 0.08% in industrialized countries, it still represents 3.8% of maternal mortality in the United States alone. In developing countries, the case fatality rate varies from 3% to 27%. Laparoscopic management of tubal pregnancies is now the standard form of treatment where this technology is available. Abdominal pregnancies are rare, and secondary implantation of tubal ectopic pregnancies is the most common cause of abdominal gestations.

It is especially prevalent in activities that involve repetitive torso movement with the torso in an extended position, such as running and horse riding. Approximately 70% of runners report experiencing the pain in the past year and in a single running event approximately one in five participants can be expected to suffer the condition. ETAP is a localized pain that is most common in the lateral aspects of the mid abdomen along the costal border, although it may occur in any region of the abdomen. It may also be related to shoulder tip pain, which is the referred site from tissue innervated by the phrenic nerve. ETAP tends to be sharp or stabbing when severe, and cramping, aching, or pulling when less intense. The condition is exacerbated by the postprandial state, with hypertonic beverages being particularly provocative. ETAP is most common in the young but is unrelated to sex or body type. Well trained athletes are not immune from the condition, although they may experience it less frequently. Several theories have been presented to explain the mechanism responsible for the pain, including ischemia of the diaphragm; stress on the supportive visceral ligaments that attach the abdominal organs to the diaphragm; gastrointestinal ischemia or distension; cramping of the abdominal musculature; ischemic pain resulting from compression of the celiac artery by the median arcuate ligament; aggravation of the spinal nerves; and irritation of the parietal peritoneum. Of these theories, irritation of the parietal peritoneum best explains the features of ETAP; however, further investigations are required. Strategies for managing the pain are largely anecdotal, especially given that its etiology remains to be fully elucidated. Commonly purported prevention strategies include avoiding large volumes of food and beverages for at least 2 hours

    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

    Acute salpingitis is an uncommon cause of an acute surgical abdomen, especially in an adolescent who is not sexually active. The following is a case of a 12-year-old girl who denied sexual activity, had a remote history of an appendectomy, and a recent diagnosis of a large, right-sided ovarian cyst, who presented with acute abdominal pain, urinary symptoms, and fever. The patient was ill-appearing and progressed to uncompensated septic shock in the emergency department despite aggressive fluid resuscitation and empiric antibiotics. She ultimately underwent an exploratory laparotomy and was diagnosed with acute bilateral salpingitis. This case highlights the diagnostic dilemmas facing those caring for an adolescent girl with abdominal pain and presents an extremely rare etiology for abdominal pain in a nonsexually active adolescent.

    Background Caregiver compliance with referrals for child health services is essential to child health outcomes. Many studies in sub-Saharan Africa have examined compliance patterns for children referred for acute, life-threatening conditions but few for children referred for non-acute conditions. The aims of this analysis were to determine the rate of referral compliance and investigate factors associated with referral compliance in KwaZulu Natal, South Africa. Methods From September 2008–2010, a door-to-door household survey was conducted to identify children aged 4–6 years in outer-west eThekwini District, KwaZulu-Natal, South Africa. Of 2,049 identified, informed consent was obtained for 1787 (89%) children who were then invited for baseline assessments. 1581 children received standardized medical and developmental assessments at the study facility (Phase 1). Children with anemia, suspected disorders of vision, hearing, behavior and/or development and positive HIV testing were referred to local health facilities. Caregiver-reported compliance with referrals was assessed 18–24 months later (Phase 2). Relationships between socio-demographic factors and referral compliance were evaluated using chi-square tests. Results Of 1581 children, 516 received referrals for ≥1 non-acute conditions. At the time of analysis, 68% (1078 /1581) returned for Phase 2. Analysis was limited to children assessed in Phase 2 who received a referral in Phase 1 (n = 303). Common referral reasons were suspected disorders of hearing/middle ear (22%), visual acuity (12%) and anemia (14%). Additionally, children testing positive for HIV (6.6%) were also referred. Of 303 children referred, only 45% completed referrals. Referral compliance was low for suspected disorders of vision, hearing and development. Referral compliance was significantly lower for children with younger caregivers, those living in households with low educational attainment and for those with unstable caregiving

    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. PMID:26192910

    [Purpose] The leg angles that are the most effective for abdominal muscle activation were investigated by performing abdominal drawing-in exercises at different leg angles with a biofeedback pressure unit. [Methods] Subjects were asked to adopt a supine position, and the tip of the biofeedback pressure unit was placed under the posterior superior iliac spine. Then, the pressure was adjusted to 40 mmHg while referring to the pressure gauge connected to the biofeedback pressure unit. Subjects were instructed to increase the pressure by 10 mmHg using the drawing-in technique upon the oral instruction, “Start,” and to maintain the drawn-in state. The time during which the pressure was maintained within an error range of ±1–2mmHg was measured in seconds. [Result] During the abdominal drawing-in exercises, the activity of the rectus abdominis, the internal and external obliques, and the transverse abdominis increased as the knee joint flexion angle increased from 45° to 120°. [Conclusion] When trunk stabilization exercises are performed at the same pressure to reduce damage after the acute phase of low back pain, trunk muscle strength can be efficiently increased by increasing the knee joint angle gradually, while performing abdominal drawing-in exercises with a biofeedback pressure unit.

    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

  4. 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

    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

    Purpose The use of abdominal computed tomography (ACT) utilization is increasing to a remarkable extent in the pediatric Emergency Department (ED), but the clinical benefit of increased use of ACT for pediatric surgical patients remains uncertain. Methods A retrospective review was conducted to investigate if, for patients who had visited pediatric ED during the last 5 years, increasing utilization of ACT would increase the detection rate of acute appendicitis, increase the detection rate of surgical conditions other than appendicitis, and decrease the hospital admission rate for surgical conditions. Results During the study period, there were 37,918 ED visits; of these, 3,274 (8.6%) were for abdominal pain, 844 (2.2%) had ACT performed. The annual proportional increase of the ACT was statistically significant (1.56% to 2.46%, P = 0.00), but the detection rate of acute appendicitis (3.3% to 5.1%) or other surgical conditions (1.7% to 2.8%) showed no statistically significant changes. Hospital admission rates (5.6% to 6.8%) also showed no significant changes during the study period. Conclusion Increasing utilization of ACT does not lead to the improved outcomes in caring for pediatric surgical patients visiting the pediatric ED. Careful evaluation for the indication for ACT is needed in the pediatric ED. PMID:25368849

  10. Intra-visceral insular cortex 2-arachidonoylglycerol, but not N-arachidonoylethanolamide, suppresses acute nausea-induced conditioned gaping in rats.

    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.

    A 47-year-old man with acute abdominal pain in the right lower quadrant underwent an appendectomy via McBurney's incision. Postoperative histology revealed a moderately differentiated adenocarcinoma in the appendix that invaded the submucosa along with lymphatic involvement. Forty-three days later, an ileocecal resection with radical lymph node dissection was performed through a midline incision. Three of the 30 resected lymph nodes were found to have adenocarcinoma metastasis. Five years later, an isolated abdominal wall recurrence occurred within the wound scar of the midline incision. A complete excision of the tumor and the invaded portion of the ileum was performed. To date, the patient has been well, with no evidence of recurrence for 5 years since the resection. The mechanism of abdominal wound recurrence is considered the leakage of carcinoma cells from transected lymph vessels during lymph node dissection, followed by the implantation of these cells into the abdominal wound.

    Abdominal pregnancy is a rare form of ectopic pregnancy which occurs due to ruptured uterine or tubal pregnancy into the abdomen. Fetal loss is a common complication of these pregnancies and patient presents with acute abdominal pain which is a surgical emergency. Another rare but established complication of this ectopic pregnancy is fetal demise with the dead fetus being retained in the abdomen. It gets macerated and mummified over a period of time and is mostly detected incidentally during imaging. Radiological imaging has hallmark appearances of such a macerated fetus showing multiple fetal parts embedded in a calcified sac termed as lithopedion or stone baby. We report a unique case of retained abdominal pregnancy for 36 years in a 60-year-old postmenopausal female presented with abdominal pain and difficulty in micturition. Computed tomography showed multiple fetal bones in the abdomen surrounded by a membrane which was surprisingly not calcified. PMID:26539374

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

    PubMed

    Pelosi, Paolo; Vargas, Maria

    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.

    Rectal prolapse is rare in children and usually benign. However, there are various diseases that can be associated with it, such as cystic fibrosis or other causes of increased abdominal pressure. Here, we review the various underlying conditions that pediatricians or pediatric gastroenterologists should consider in the case of rectal prolapse. We report on three cases of children with a rectal prolapse and intra-abdominal tumors. Current recommendations and practice do not include a systematic check via abdominal imaging in cases of rectal prolapse. However, in some situations, imaging is indicated to detect a possible expansive process. Thus, in the presence of recurrent prolapse or of associated urinary or neurological signs, imaging is justified so as to allow for an early diagnosis and treatment of these neoplasms. Given its lack of radiation exposure and good sensitivity in children, ultrasound imaging is the first choice. PMID:27265581

    The effect of ACTH-(4-7)-PGP (semax) intraperitoneal injection at doses of 5, 50, 150 and 450 μg/kg b.w. on the free-radical oxidation and the activity of serum transaminases in Wistar male rats subjected to acute and chronic immobilization stress has been studied. It was found that the peptide administration in the entire dose range studied produced antioxidant effect in hepatocytes and significantly increased the activity of serum ALT and AST at a dose of 450 μg/kg under chronic stress conditions. On the contrary, prooxidant effects were observed at a drug dose of 150 mg/kg under acute stress conditions, and the direction of changes in the ALT and AST values activity depended on the semax dose. The ALT activity was decreased at doses of 5 and 50 μg/kg, but increased at a dose of 450 μg/kg. The AST activity was already reliably increased at a dose of 5 μg/kg. PMID:26591577

    Increasing numbers of patients are receiving reduced intensity conditioning regimen allogeneic hematopoietic stem cell transplantation. We hypothesized that the use of bone marrow graft might decrease the risk of graft-versus-host disease compared to peripheral blood after reduced intensity conditioning regimens without compromising graft-versus-leukemia effects. Patients who underwent reduced intensity conditioning regimen allogeneic hematopoietic stem cell transplantation from 2000 to 2012 for acute leukemia, and who were reported to the Acute Leukemia Working Party of the European Group for Blood and Marrow Transplantation were included in the study. Eight hundred and thirty-seven patients receiving bone marrow grafts were compared with 9011 peripheral blood transplant recipients after reduced intensity conditioning regimen. Median follow up of surviving patients was 27 months. Cumulative incidence of engraftment (neutrophil ≥0.5×10(9)/L at day 60) was lower in bone marrow recipients: 88% versus 95% (P<0.0001). Grade II to IV acute graft-versus-host disease was lower in bone marrow recipients: 19% versus 24% for peripheral blood (P=0.005). In multivariate analysis, after adjusting for differences between both groups, overall survival [Hazard Ratio (HR) 0.90; P=0.05] and leukemia-free survival (HR 0.88; P=0.01) were higher in patients transplanted with peripheral blood compared to bone marrow grafts. Furthermore, peripheral blood graft was also associated with decreased risk of relapse (HR 0.78; P=0.0001). There was no significant difference in non-relapse mortality between recipients of bone marrow and peripheral blood grafts, and chronic graft-versus-host disease was significantly higher after peripheral blood grafts (HR 1.38; P<0.0001). Despite the limitation of a retrospective registry-based study, we found that peripheral blood grafts after reduced intensity conditioning regimens had better overall and leukemia-free survival than bone marrow grafts

Grade II to IV acute graft-versus-host disease was lower in bone marrow recipients: 19% versus 24% for peripheral blood (P=0.005). In multivariate analysis, after adjusting for differences between both groups, overall survival [Hazard Ratio (HR) 0.90; P=0.05] and leukemia-free survival (HR 0.88; P=0.01) were higher in patients transplanted with peripheral blood compared to bone marrow grafts. Furthermore, peripheral blood graft was also associated with decreased risk of relapse (HR 0.78; P=0.0001). There was no significant difference in non-relapse mortality between recipients of bone marrow and peripheral blood grafts, and chronic graft-versus-host disease was significantly higher after peripheral blood grafts (HR 1.38; P<0.0001). Despite the limitation of a retrospective registry-based study, we found that peripheral blood grafts after reduced intensity conditioning regimens had better overall and leukemia-free survival than bone marrow grafts.

    A random retrospective review of hepatobiliary scans on 86 adult patients with abdominal pain revealed four distinct imaging patterns: normal, cystic duct obstruction, obstructive, and sick liver pattern. A normal pattern was found to exclude acute cholecystitis and was the pattern most frequently observed.

    We developed a technology of creating computer models of acute surgical diseases of abdominal cavity organs on the basis of the pattern recognition theory and multifactor analysis of traditional symptomatology. We employed an algorithm consisting of the method of evaluating vectors and method of patterns that rests on special rules of extended production for solving medicinal problems.

    Diagnostics of inflammatory-destructive diseases of the abdominal cavity organs is performed by the determined spectra of luminescence of venous blood plasma. The shift of the photoluminescence maximum beginning with the wavelength 474 nm into short-wave zone proves the presence of the acute inflammatory-destructive diseases and exacerbation of the pathological process.

    Periphyton communities are an integral component of freshwater ecosystems and the desire to include data from toxicity testing with these organisms for ecological risk assessment is growing. This study developed sampling, storage, and exposure methods for the consistent and effective characterization of acute response and recovery of field-derived periphyton to photosystem II (PSII) inhibiting herbicides, particularly atrazine. Pulse amplitude modulated fluorometry was used to assess PSII quantum yield. For the method development phase, periphyton samples were collected from lotic and lentic systems in the Guelph, Ontario, Canada area during the summer of 2011. Following method development, native periphyton communities from three agricultural streams from the midwestern U.S. were sampled and exposed to atrazine (10-320 μg/L) and assessed for inhibition of PSII quantum yield (from 2 up to 24 h) and subsequent recovery upon cessation of exposure (up to 48 h post-exposure). Sensitivity to atrazine (EC10 and EC50 values) varied slightly (typically less than twofold difference) by site, date of sampling, and exposure interval. Only the highest initial test concentrations (160 or 320 μg/L) demonstrated greater than ~5% inhibition at 48 h post-exposure; however all other test concentrations recovered to within 5% of control levels, typically within 24 h. The rapid physiological recovery of periphyton communities upon atrazine removal supports the conclusion that acute exposure will not likely result in significant or sustained impacts on either structure or function of periphyton in lotic ecosystems. For ecological risk assessment, this suggests the current approach of relying on direct effects data for the most sensitive single species alone may result in overly conservative estimates of potential effects, especially for complex communities of primary producers.

    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.

    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

    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 obesity and metabolic syndrome (MS) are multifactorial conditions associated with increased risk of cardiovascular disease and type II diabetes mellitus. Previous work has demonstrated that the hemorheological profile is altered in patients with abdominal obesity and MS, as evidenced for example by increased whole blood viscosity. To date, however, no studies have examined red blood cell (RBC) deformability of blood from individuals with obesity or metabolic abnormalities under typical physiological flow conditions. In this study, we pumped RBCs through a constriction in a microfluidic device and used high speed video to visualize and track the mechanical behavior of ~8,000 RBCs obtained from either healthy individuals (n = 5) or obese participants with metabolic abnormalities (OMA) (n = 4). We demonstrate that the OMA+ cells stretched on average about 25% less than the healthy controls. Furthermore, we examined the effects of ingesting a high-fat meal on RBC mechanical dynamics, and found that the postprandial period has only a weak effect on the stretching dynamics exhibited by OMA+ cells. The results suggest that chronic rigidification of RBCs plays a key role in the increased blood pressure and increased whole blood viscosity observed in OMA individuals and was independent of an acute response triggered by consumption of a high-fat meal.

    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

    Incisional hernia is one of the classic complications after abdominal surgery. The chronic, gradual increase in size of some of these hernias is such that the hernia ring widens to a point where there is a loss of substance in the abdominal wall, herniated organs can become incarcerated or strangulated while poor abdominal motility can alter respiratory function. The surgical treatment of small (<5 cm) incisional hernias is safe and straightforward, by either laparotomy or laparoscopy. For large hernias, surgical repair is often difficult. After reintegration of herniated viscera into the abdominal cavity, the abdominal wall defect must be closed anatomically in order to restore the function to the abdominal wall. Prosthetic reinforcement of the abdominal wall is mandatory for long-term successful repair. There are multiple techniques for prosthetic hernia repair, but placement of Dacron mesh in the retromuscular plane is our preference. PMID:23137643

    Actinomycosis is a chronic suppurative granulomatous infectious disease caused by actinomyces species that is characterized by formation of characteristic clumps called as sulfur granules. Abdominal actinomycosis is a rare disease and is often difficult to diagnose before operation. Abdominal actinomycosis infiltrating into the abdominal wall and adhering to the colon is even rarer. Most abdominal actinomycosis develops after operation, trauma or inflammatory bowel disease, and is also considered as an opportunistic infection in immunocompromised patient with underlying malignancy, diabetes mellitus, human immunodeficiency virus infection, etc. Actinomycosis is diagnosed based on histologic demonstration of sulfur granules in surgically resected specimen or pus, and treatment consists of long-term penicillin based antibiotics therapy with or without surgical resection. Herein, we report an unusual case of abdominal wall actinomycosis which developed in a patient after acupuncture and presented as abdominal wall mass that was first mistaken for abdominal wall invasion of diverticulum perforation.

    Cytomegalovirus (CMV) reactivation after allogeneic hematopoietic cell transplant (allo-HCT) has been associated with a reduced risk of relapse in patients with acute myeloid leukemia (AML). However, the influence of the conditioning regimen on this protective effect of CMV reactivation after allo-HCT is relatively unexplored. To address this, we evaluated the risk of relapse in 264 AML patients who received T cell-replete, 6/6 HLA matched sibling or 10/10 HLA matched unrelated donor transplantation at a single institution between 2006 and 2011. Of these 264 patients, 206 received myeloablative (MA) and 58 received reduced-intensity conditioning (RIC) regimens. CMV reactivation was observed in 88 patients with MA conditioning and 37 patients with RIC. At a median follow-up of 299 days, CMV reactivation was associated with significantly lower risk of relapse in patients who received MA conditioning both in univariate (P = .01) and multivariate analyses (hazard ratio, .5246; P = .006); however, CMV reactivation did not significantly affect the risk of relapse in our RIC cohort. These results confirm the protective effect of CMV reactivation on relapse in AML patients after allo-HCT reported by previous studies but suggest this protective effect of CMV reactivation on relapse is influenced by the conditioning regimen used with the transplant.

    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

    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.

    A 38-year-old African American woman presenting with acute abdominal pain and nonobstructive renal failure was found to have an enlarged fibroid uterus. A differential for sepsis was considered. Lab evaluation revealed an elevated creatinine and myoglobin level at 3.9 mg/dL and 2140 ng/mL, respectively. Ongoing hemodynamic instability mandated surgery for acute abdomen. A 25 cm fibroid uterus was extirpated through a total abdominal hysterectomy. Immediate improvement of acute nephropathy mirrored the postoperative decline in serum myoglobin levels. Myoglobinemia from a massive degenerating fibroid is associated with nonobstructive acute renal failure. PMID:27375910

    One of the most feared complications following a massive ventral hernia repair is abdominal compartment syndrome (ACS). ACS is caused by an acute increase in intra-abdominal pressure (IAP), which can lead to multi-organ dysfunction and ultimately result in death. Component separation repair (CST) has been successful for most large hernia repairs in reducing the risk of ACS by increasing abdominal volume and reducing abdominal wall tension during a tight closure. However, reduction of a large hernia can lead to elevated IAP and possible progression to ACS. Here, we describe the detailed intra-operative and post-operative course of a patient who developed abdominal compartment syndrome following CST repair. PMID:25739715

    Acute pancreatitis is probably commoner in children than was previously thought. In children it is most commonly associated with trauma or viral infection. The presentation may be subtler than in adults, requiring a high index of suspicion in the clinician. In three children, two boys aged 4 and 10 and a girl of 15 years, acute pancreatitis was suspected because of the findings at ultrasonography and endoscopic retrograde cholangiopancreatography performed when the disease recurred (the boy aged 4), apathy and immobility without dehydration or other obvious causes (the boy aged 10), and severe abdominal pain in combination with vomiting (the girl). All three patients had severely increased (urinary) amylase levels. Most often, acute pancreatitis in children tends to be a self-limiting disease which responds well to conservative 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.

    During adolescence, some individuals with autism spectrum disorder (ASD) engage in severe challenging behaviors, such as aggression, self-injury, disruption, agitation and tantrums. We aimed to assess risk factors associated with very acute behavioral crises in adolescents with ASD admitted to a dedicated neurobehavioral unit. We included retrospectively in 2008 and 2009 29 adolescents and young adults with ASD hospitalized for severe challenging behaviors and proposed a guideline (Perisse et al., 2010) that we applied prospectively for 29 patients recruited for the same indications between 2010 and 2012. In total, 58 patients were admitted (n=70 hospitalizations, mean age=15.66 (±4.07) years, 76% male). We systematically collected data describing socio-demographic characteristics, clinical variables (severity, presence of language, cognitive level), comorbid organic conditions, etiologic diagnosis of the episode, and treatments. We explored predictors of Global Assessment Functioning Scale (GAFS) score and duration of hospitalization at discharge. All but 2 patients exhibited severe autistic symptoms and intellectual disability (ID), and two-thirds had no functional verbal language. During the inpatient stay (mean=84.3 (±94.9) days), patients doubled on average their GAFS scores (mean=17.66 (±9.05) at admission vs. mean=31.4 (±9.48) at discharge). Most common etiologies for acute behavioral crises were organic causes [n=20 (28%), including epilepsy: n=10 (14%) and painful medical conditions: n=10 (14%)], environmental causes [n=17 (25%) including lack of treatment: n=11 (16%) and adjustment disorder: n=6 (9%)], and non-ASD psychiatric condition [n=33 (48%) including catatonia: n=5 (7%), major depressive episode: n=6 (9%), bipolar disorder: n=4 (6%), schizophrenia: n=6 (9%), other/unknown diagnosis: n=12 (17%)]. We found no influence of age, gender, socio-economic status, migration, level of ID, or history of seizure on improvement of GAFS score at discharge

    Introduction Although intra-abdominal hypertension (IAH) and abdominal compartment syndrome (ACS) are associated with substantial morbidity and mortality among critically ill adults, it remains unknown if prevention or treatment of these conditions improves patient outcomes. We sought to identify evidence-based risk factors for IAH and ACS in order to guide identification of the source population for future IAH/ACS treatment trials and to stratify patients into risk groups based on prognosis. Methods We searched electronic bibliographic databases (MEDLINE, EMBASE, PubMed, and the Cochrane Database from 1950 until January 21, 2013) and reference lists of included articles for observational studies reporting risk factors for IAH or ACS among adult ICU patients. Identified risk factors were summarized using formal narrative synthesis techniques alongside a random effects meta-analysis. Results Among 1,224 citations identified, 14 studies enrolling 2,500 patients were included. The 38 identified risk factors for IAH and 24 for ACS could be clustered into three themes and eight subthemes. Large volume crystalloid resuscitation, the respiratory status of the patient, and shock/hypotension were common risk factors for IAH and ACS that transcended across presenting patient populations. Risk factors with pooled evidence supporting an increased risk for IAH among mixed ICU patients included obesity (four studies; odds ratio (OR) 5.10; 95% confidence interval (CI), 1.92 to 13.58), sepsis (two studies; OR 2.38; 95% CI, 1.34 to 4.23), abdominal surgery (four studies; OR 1.93; 95% CI, 1.30 to 2.85), ileus (two studies; OR 2.05; 95% CI, 1.40 to 2.98), and large volume fluid resuscitation (two studies; OR 2.17; 95% CI, 1.30 to 3.63). Among trauma and surgical patients, large volume crystalloid resuscitation and markers of shock/hypotension and metabolic derangement/organ failure were risk factors for IAH and ACS while increased disease severity scores and elevated creatinine were

    2013-01-01

    Introduction Advanced abdominal (extrauterine) pregnancy is a rare condition with high maternal and fetal morbidity and mortality. Because the placentation in advanced abdominal pregnancy is presumed to be inadequate, advanced abdominal pregnancy can be complicated by pre-eclampsia, which is another condition with high maternal and perinatal morbidity and mortality. Diagnosis and management of advanced abdominal pregnancy is difficult. Case presentation We present the case of a 33-year-old African woman in her first pregnancy who had a full-term advanced abdominal pregnancy and developed gross ascites post-operatively. The patient was successfully managed; both the patient and her baby are apparently doing well. Conclusion Because most diagnoses of advanced abdominal pregnancy are missed pre-operatively, even with the use of sonography, the cornerstones of successful management seem to be quick intra-operative recognition, surgical skill, ready access to blood products, meticulous post-operative care and thorough assessment of the newborn.

    Acute Fulminant Necrotizing Amoebic Colitis is a rare complication of amoebiasis that is associated with high mortality. Only one to four such cases are seen per year in large hospitals of India, and only few such cases have been reported in the literature. The condition requires early diagnosis and surgical intervention. We recently cared for a patient who presented with acute abdomen with history of intermittent abdominal pain and diarrhea. Before presenting to our institution he was misdiagnosed as a case of inflammatory bowel disease and had been treated with steroids. On emergency exploration, extensive necrosis and multiple perforations in retroperitoneum involving entire colon were seen. Total colectomy with ileostomy was performed. Postoperative course was marked by septicaemia and multi-organ failure followed by death. This case report emphasizes the importance of early diagnosis and treatment of acute FAC, and associated high mortality. PMID:19918532

The serum creatinine and urea nitrogen on admission were 4.59 and 42.5 mg/dl and rose to 13.5 and 72.4 mg/dl, respectively, at the 6th hospital day. Oliguria lasted only 48 hours. Dialysis was not used, since the patient was in good general condition and uremic symptoms were absent. On the 7th day, azotemia began to subside and at the 14th day, serum creatinine was 1.0 mg/dl. Before hospital discharge, she confessed the ingestion of 2.000 mg of phenazopyridine, during a nervous breakdown, aiming to sleep deeply. Remarkable was the persistence of the orange color of her urine during several days and the dissociation between the rate of increase of serum creatinine with respect to urea nitrogen. This is an unusual case of acute renal failure caused by an overdose of a drug, commonly prescribed for urinary tract infections. PMID:12879816

    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

    Arterial thrombosis or emboli have rarely been reported in Cushing syndrome (CS). Here we describe the first case of mesenteric ischaemia secondary to ventricular emboli in a patient with CS. Laboratory evaluation showed increased fibrinogen and factor VIII. Previous studies showed that venous thromboembolism (VTE) increases in CS. This case for the first time described arterial system thrombosis and emboli in a patient with adrenocorticotropin (ACTH)-dependent CS. PMID:25943108

    The growing popularity of nonoperative treatment of children with splenic injuries has seduced some physicians into a false sense of security regarding care of the injured child. Although it has been established that hemodynamically stable children with splenic, hepatic, and even renal injuries can safely be treated "expectantly," this concept cannot be applied indiscriminately. Accurate diagnosis and effective care of the child with blunt abdominal trauma is an exercise of clinical precision that demands attention to detail and thorough evaluation. This review addresses this process in light of recent advances in diagnostic imaging and in consideration of recent reports analyzing different protocols for therapeutic decision making.

    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

    Background Attacks of neuropathic pain, usually abdominal, are characteristic of the acute porphyrias and are accompanied by overproduction of heme-precursor molecules, specifically delta-aminolevulinic acid and porphobilinogen. The basis for the acute symptoms in these diseases has been speculative. Methods We review genetic acute porphyria, hereditary tyrosinemia, and an acquired condition, lead poisoning. All perturb heme synthesis and present with a very similar pain syndrome. Results While each of these conditions has characteristic urine biochemistry, all exhibit excess delta-aminolevulinic acid. Moreover, in all, treatment with hemin reduces delta-aminolevulinic acid and relieves symptoms. In contrast, use of recombinant porphobilinogen deaminase to knock down porphobilinogen in acute porphyria was ineffective. Conclusion There is now convincing evidence that delta-aminolevulinic acid is the cause of pain in the acute porphyrias. The efficacy of hemin infusion is due mainly, if not entirely, to its inhibition of hepatic delta-aminolevulinic acid synthase-1, the enzyme that catalyzes delta-aminolevulinic acid formation. Delta-aminolevulinic acid synthase-1 is a rational target for additional therapies to control symptoms in acute porphyria. PMID:25446301

    Abdominal compartment syndrome is a surgical emergency caused by a raised intra-abdominal pressure, which may lead to respiratory, cardiovascular and renal compromise. It is most commonly seen in post-operative and trauma patients and it has a variety of causes. Tension pneumoperitoneum (TP) is a rare cause of abdominal compartment syndrome most often seen after gastrointestinal endoscopy with perforation. We present the case of a fit 52-year-old experienced female diver who developed TP and shock following a routine training dive to 27m. Following accidental inhalation of water, she had an unstaged ascent and, on reaching the surface, developed severe acute abdominal pain and distension. She was brought to our emergency department by air ambulance for assessment. Clinical and radiological examination revealed a shocked patient with dramatic free intra-abdominal gas and signs of abdominal compartment syndrome, which was treated with needle decompression. Symptoms and signs resolved quickly with no need for further surgical intervention. TP is a surgical emergency where surgery can be avoided with prompt diagnosis and treatment. PMID:23131212

    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

    Introduction a Meckel’s diverticulum is one of the most common congenital anomalies of the digestive tract. The reported lifetime complication rate is 4%, mostly due to hemorrhage, obstruction, perforation or inflammation. A symptomatic Meckel’s diverticulum due to rupture after blunt abdominal trauma is very rare. We believe this case report is the first reporting a rupture of a Meckel’s diverticulum after a low velocity blunt abdominal trauma and outlining the importance of a thorough and complete examination of the patient after blunt abdominal trauma. Presentation of case a 17-year-old male presented with abdominal pain after blunt abdominal trauma during a soccer game. Physical examination showed signs of peritonitis in all quadrants of the abdomen. During admission the patient deteriorated with decreasing blood pressure and raising pulse rate. A CT-scan showed free abdominal fluid. Our patient was scheduled for an emergent laparotomy where a perforated Meckel’s diverticulum with fecal spill was found. A segmental ileal resection was performed. Post-operative, patient developed a pneumonia and also intra-abdominal abscesses treated with percutaneous drainage. After an admission period of 17-days the patient was discharged. Conclusion perforation of a Meckel’s diverticulum is rarely suspected as a cause of acute deterioration following blunt abdominal trauma. This case shows the importance of awareness of this kind of injury especially in male patients. PMID:26701844

    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.

    Solid organ abdominal ischemia commonly presents with acute pain prompting radiologic evaluation and often requires urgent treatment. Despite different risk factors and anatomic differences, most solid organ ischemia is due to arterial or venous occlusion and, less frequently, a low-flow state. Radiologic diagnosis is critical, as clinical presentations are often nonspecific. Contrast-enhanced computed tomography (CT) is the modality of choice (except in adnexal torsion) with magnetic resonance imaging (MRI) useful in equivocal cases or follow-up of ischemic disease. This article will provide a pictorial review of the CT and MRI features of solid abdominal organ ischemia while highlighting key clinical features, etiology, and management. PMID:27317217

    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. PMID:27031165

    Acute cholecystitis is a rare complication of scrub typhus. Although a few such cases have been reported in patients with scrub typhus, the clinical course is not well described. Of 12 patients, acute cholecystitis developed in 66.7% (8/12) of patients older than 60 yr. The scrub typhus group with acute cholecystitis had marginal significant longer hospital stay and higher cost than the group without cholecystitis according to propensity score matching. Scrub typhus should be kept in mind as a rare etiology of acute cholecystitis in endemic areas because the typical signs of scrub typhus such as skin rash and eschar can present after the abdominal pain.

    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.

  19. Involvement of Glutamate NMDA Receptors in the Acute, Long-Term, and Conditioned Effects of Amphetamine on Rat 50kHz Ultrasonic Vocalizations

    PubMed Central

    Costa, Giulia; Morelli, Micaela

    2015-01-01

    Background: Rats emit 50kHz ultrasonic vocalizations (USVs) in response to either natural or pharmacological pleasurable stimuli, and these USVs have emerged as a new behavioral measure for investigating the motivational properties of drugs. Earlier studies have indicated that activation of the dopaminergic system is critically involved in 50kHz USV emissions. However, evidence also exists that non-dopaminergic neurotransmitters participate in this behavioral response. Methods: To ascertain whether glutamate transmission plays a role in 50kHz USV emissions stimulated by amphetamine, rats received five amphetamine (1–2mg/kg, i.p.) administrations on alternate days in a test cage, either alone or combined with the glutamate N-methyl-D-aspartate receptor antagonist MK-801 (0.1–0.5mg/kg, i.p.). Seven days after treatment discontinuation, rats were re-exposed to the test cage to assess drug conditioning, and afterwards received a drug challenge. USVs and locomotor activity were evaluated, along with immunofluorescence for Zif-268 in various brain regions and spontaneous alternation in a Y maze. Results: Amphetamine-treated rats displayed higher 50kHz USV emissions and locomotor activity than vehicle-treated rats, and emitted conditioned vocalizations on test cage re-exposure. Rats co-administered amphetamine and MK-801 displayed lower and dose-dependent 50kHz USV emissions, but not lower locomotor activity, during repeated treatment and challenge, and scarce conditioned vocalization compared with amphetamine-treated rats. These effects were associated with lower levels of Zif-268 after amphetamine challenge and spontaneous alternation deficits. Conclusions: These results indicate that glutamate transmission participates in the acute, long-term, and conditioned effects of amphetamine on 50kHz USVs, possibly by influencing amphetamine-induced long-term neuronal changes and/or amphetamine-associated memories.

    Reduced intensity conditioning/non-myeloablative conditioning regimens are increasingly used in allogeneic hematopoietic cell transplantation (HCT). Reports have shown CD34+ dose to be important for transplant-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/non-myeloablative HCT. We studied 1,054 patients aged 45–75 years, with acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS) transplanted between 2002 and 2011. Results of multivariate analysis showed that PBPC from HLA-matched siblings containing <4 × 106 CD34+/kg were associated with higher non-relapse mortality (HR 2.03, p=0.001), overall mortality (HR 1.48, p=0.008), and lower neutrophil (OR 0.76, p=0.03) and platelet (OR 0.76, p=0.03) recovery. PBPC from unrelated donors with CD34+ dose <6 × 106 CD34+/kg were also associated with higher non-relapse (HR 1.38, p=0.02) and overall mortality (HR 1.20, p=0.05). 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+ dose >4 × 106 CD34+/kg and >6 × 106 CD34+/kg are optimal for HLA-matched sibling and unrelated donor HCT, respectively. PMID:24892261

In the absence of consensus definitions and treatment guidelines, the diagnosis and management of intra-abdominal hypertension and abdominal compartment syndrome remains variable from institution to institution. Case presentation We report the occurrence of the extravasation of fluid into the abdomen during arthroscopic treatment of femoroacetabular impingement combined with resection of trochanteric bursa and our management of the condition in a 55-year old Caucasian woman. Conclusions We present an algorithm of treatment of abdominal compartment syndrome, as a hip arthroscopy complication, according to the consensus definitions and recommendations of the World Society of the Abdominal Compartment Syndrome. In the algorithm options, we have included paracentesis and percutaneous catheter decompression as the main point of treatment. Our algorithm will have a broader clinical impact on orthopedic surgery, anesthesiology and emergency medicine. PMID:25394557

    Summary Graft-versus-host disease (GVHD) is partly mediated by host antigen presenting cells (APCs) that activate donor T-cells. Extracorporeal photopheresis (ECP) can modulate APC function and benefit some patients with GVHD. We report the results of a study using ECP administered prior to a standard myeloablative preparative regimen intended to prevent GVHD. Grade II-IV aGVHD developed in 9 (30%) of 30 recipients of HLA-matched related transplants and 13 (42%) of 31 recipients of HLA-matched unrelated or HLA-mismatched related donor transplants. Actuarial estimates of overall survival (OS) at day 100 and 1 year post transplant were 89% (95% CI, 78%-94%) and 77% (95% CI, 64%-86%), respectively. There were no unexpected adverse effects of ECP. Historical controls receiving similar conditioning and GVHD prophylaxis regimens but no ECP were identified from the database of the Center for International Blood and Marrow Transplant Research and multivariate analysis indicated a lower risk of grade II-IV aGVHD in patients receiving ECP (p=0.04). Adjusted OS at one year was 83% in the ECP study group and 67% in the historical control group (relative risk 0.44, 95% CI, 0.24-0.80) (p= 0.007). These preliminary data may indicate a potential survival advantage with ECP for transplant recipients undergoing standard myeloablative hematopoietic cell transplantation. PMID:19915634

    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.

    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

    Our purpose was to examine the influence of steady-state changes in chemical stimuli, as well as discrete peripheral chemoreceptor stimulation, on abdominal expiratory motor activity. In decerebrate, paralyzed, vagotomized, and ventilated cats that had bilateral pneumothoraces, we recorded efferent activity from a phrenic nerve and from an abdominal nerve (cranial iliohypogastric nerve, L1). All cats showed phasic expiratory abdominal nerve discharge at normocapnia [end-tidal PCO2 38 +/- 2 Torr], but small doses (2-6 mg/kg) of pentobarbital sodium markedly depressed this activity. Hyperoxic hypercapnia consistently enhanced abdominal expiratory activity and shortened the burst duration. Isocapnic hypoxia caused inhibition of abdominal nerve discharge in 11 of 13 cats. Carotid sinus nerve denervation (3 cats) exacerbated the hypoxic depression of abdominal nerve activity and depressed phrenic motor output. Stimulation of peripheral chemoreceptors with NaCN increased abdominal nerve discharge in 7 of 10 cats, although 2 cats exhibited marked inhibition. Four cats with intact neuraxis, but anesthetized with ketamine, yielded qualitatively similar results. We conclude that when cats are subjected to steady-state chemical stimuli in isolation (no interference from proprioceptive inputs), hypercapnia potentiates, but hypoxia attenuates, abdominal expiratory nerve activity. Mechanisms to explain the selective inhibition of expiratory motor activity by hypoxia are proposed, and physiological implications are discussed. PMID:3624126

    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.

    The purpose of this review is to investigate the utility of autotransfusion in trauma patients in the past 3 years. A retrospective review was conducted of the charts for whom the Haemonetics Cell Saver autotransfusion device (Haemonetics Corp., Natick, MA) was utilized between January 1, 1993, and December 31, 1995. The estimated blood loss and quantity of blood transfused were noted for abdominal trauma patients. Costs of autotransfusion were then compared to estimated blood bank costs for this group. The Haemonetics Cell Saver autotransfusion device was requested for 592 cases from January 1, 1993, to December 31, 1995. Nonorthopedic trauma cases comprised 25 per cent of all autotransfusion cases. One hundred twenty-six patients had isolated abdominal trauma and had a mean estimated blood loss of 4864 +/- 6070 cc. The average volume of intraoperatively salvaged autologous blood transfused (autotransfusion) per patient was 1547 +/- 2359 cc, or a bank blood equivalent of 6.9 units of packed red blood cells. The total cost of autotransfusion in these patients was $63,252.00. Had bank blood been used instead of salvaged autologous blood, the cost would have been $114,523.00; thus, autotransfusion resulted in a savings of $51,271.00. The use of salvaged autologous blood comprised 45 per cent of total blood transfused. On a case-by-case basis, 75 per cent of cases were cost-effective compared to blood bank costs for an equivalent transfusion. Transfusion of intraoperatively salvaged autologous blood (autotransfusion) is a cost-effective, efficient way to provide blood products to operative trauma patients. PMID:8985070

    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.

    Intramural gas in stomach is a rare finding, but differential diagnosis of this condition into gastric emphysema and emphysematous gastritis is clinically important because of vastly different aetiologies and prognosis. Emphysematous gastritis is caused by gas producing micro-organisms inside the stomach wall and is a potentially fatal condition, while, on the other hand, gas enters stomach wall through mucosal breach in the case of gastric emphysema and prognosis is usually good with complete resolution. To date, no case has been reported in the literature showing gas in the stomach wall in a patient with acute calculus cholecystitis. We present a case of a young man with upper abdominal pain, and who, upon diagnostic work up was diagnosed with acute calculus cholecystitis with associated intramural gas in the stomach with no known aetiological factors to be positive. Conservative management with close observation resulted in complete symptomatic resolution. PMID:23645637

    A 46-year-old female patient developed severe abdominal pain shortly after taking levofloxacin, 1000 mg for acute bacterial sinusitis. The pain started after taking the first dose of levofloxacin and became worse after the second dose. The patient was unable to do daily physical activities. The pain resolved upon discontinuation of levofloxacin and symptomatic therapy. Other factors that may cause abdominal pain were ruled out. This case is of interest as it documents severe abdominal pain due to levofloxacin requiring discontinuation of therapy and describes its appropriate management. In addition, it highlights the vital role that community pharmacists could play in managing adverse drug reactions (ADRs) and preventing potential Drug Related Problems (DRPs). PMID:23960849

    2013-01-01

    Coarctation of the abdominal aorta is extremely rare. It generally involves a long segment of the descending aorta and causes uncontrolled and unexplainable hypertension in children. The therapeutic choice is very challenging because acute and chronic complications are reported for both the surgical and the percutaneous approaches. The two reported cases of abdominal coarctation were treated primarily and successfully through the use of covered stents. Three covered stents were implanted in two children. No complication occurred with either procedure. At this writing, an 18-month follow-up assessment has found the patients in good health with no restenosis at the coarctation site. Covered stent implantation in children with abdominal coarctation is a feasible, safe, and effective procedure. It provides adequate relief of symptoms and reduces the risk of aneurysm formation. To avoid covering important side branches with polytetrafluoroethylene, this type of procedure must be preceded by precise study of the aorta and its branches. PMID:23515761

    Epiploic appendagitis is a rare cause of focal abdominal pain which, depending on its localisation, can mimic a variety of abdominal diseases. We report a case of 36-year-old woman who presented with a classic signs of acute appendicitis. On examination, the obese, afebrile, and had very strong right iliac fossa tenderness and guarding. The white cell count was 12.82 x 10(9)/L, and C reactive protein count was 15.13MG/DL. She underwent emergency laparoscopic procedure after the acute appendicitis diagnosis has been established. Laparoscopic exploration of the abdominal cavity showed vermiform, no inflamed, appendix and necrotic appendix epiploica of the caecum. The treatment consisted of typical laparoscopic appendectomy and laparoscopic resection of the necrotic appendix epiploica. The patient made rapid recovery and was discharged from the hospital on second day after the operation. Histological investigation of the appendix epiploica revealed gangrenous epiploic appendage.

    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. PMID:26992633

    PURPOSE To validate serum neutrophil gelatinase-associated lipocalin (NGAL) as an early biomarker for acute kidney injury (AKI) in sepsis-related conditions and its predictive and prognostic values. PATIENTS AND METHODS This study included 65 patients, who were clinically evaluated for sepsis, severe sepsis, or septic shock, and 20 apparently healthy served as controls. Patients were divided into two groups: Group I (AKI-sepsis): 65 newly admitted patients diagnosed as sepsis, who were further divided into three subgroups according to the severity: systemic inflammatory response syndrome, severe sepsis, and septic shock, and Group II (control group): 20 apparently healthy subjects matched for age and sex, serum creatinine and serum NGAL concentrations were estimated initially within 24 hours of admission and after 72 hours of admission in all patients and control groups. RESULTS Serum NGAL increased significantly with increasing severity of renal impairment. Receiver-operating characteristic analysis suggested that serum NGAL cutoff value of 40 ng/mL within the first 24 hours of admission is highly specific and sensitive for predicting AKI, with sensitivity of 90.9% and specificity of 75.8%. CONCLUSION We concluded that early measurement of serum NGAL level in sepsis can serve as a clinically useful marker for early prediction of AKI and for grading of its severity. PMID:27547045

    Blunt abdominal aortic trauma is a rare occurrence in children with only a few patients having been reported in the literature. Most such cases have been described in the context of lap belt injuries. We report a 9-year-old boy who suffered lap belt trauma to the abdomen during a high-speed road traffic accident resulting to the well-recognized pattern of blunt abdominal injury, that is, the triad of intestinal perforation, fractures of the lumbar spine, and abdominal aortic injury. The latter presented with lower limb ischemia due to dissection of the infrarenal aorta and right common iliac artery. Revascularization was achieved by endovascular means using 2 self-expanding stents in the infrarenal aorta and the right common iliac artery. This case is one of the few reports of lap belt-related acute traumatic abdominal aortic dissection in a young child and highlights the feasibility of endovascular management in the pediatric population.

    This study prospectively analyzed outcomes in 49 consecutive patients undergoing temporary abdominal closure (TAC) between 1993 and 1996 at a single university hospital. There were 37 males and 12 females, mean age was 57 years (range, 25-79 years), mean Acute Physiology and Chronic Health Evaluation score was 27 (+7.8 SD), and mean Simplified Acute Physiology II score was 53.0 (+/-15.4). The reason for TAC was decompression in 22 patients, inability to close the abdomen in 10 patients, to facilitate reexploration for sepsis in 8 patients, and multifactorial in 9 patients. After TAC, there was a significant reduction in intra-abdominal pressure from 24.2+/-9.3 to 14.1+/-5.5 mm Hg and improvement in lung dynamic compliance from 24.1+/-7.9 to 27.6+/-9.4 mL/cm H2O (p < 0.05). Although 10 patients experienced brisk diuresis, there was no significant improvement in renal function; in fact, serum creatinine increased. The median length of stay was 35 days (range, 1-232 days). The mean number of abdominal operations after mesh insertion was 2.6+/-2.4. There were 21 deaths, for a standardized mortality rate of 0.80. Although it achieved significant reductions in abdominal pressures and improved lung dynamic compliance, TAC did not result in improved renal function or patient oxygenation. PMID:9820703

    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.

    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

    Background Mesenchymal stromal cells (MSC) are shown to have a great therapeutic potential in many immunological disorders. Currently the therapeutic effect of MSCs is considered to be mediated via paracrine interactions with immune cells. Umbilical cord blood is an attractive but still less studied source of MSCs. We investigated the production of extracellular membrane vesicles (MVs) from human umbilical cord blood derived MSCs (hUCBMSC) in the presence (MVstim) or absence (MVctrl) of inflammatory stimulus. Methods hUCBMSCs were cultured in serum free media with or without IFN-γ and MVs were collected from conditioned media by ultracentrifugation. The protein content of MVs were analyzed by mass spectrometry. Hypoxia induced acute kidney injury rat model was used to analyze the in vivo therapeutic potential of MVs and T-cell proliferation and induction of regulatory T cells were analyzed by co-culture assays. Results Both MVstim and MVctrl showed similar T-cell modulation activity in vitro, but only MVctrls were able to protect rat kidneys from reperfusion injury in vivo. To clarify this difference in functionality we made a comparative mass spectrometric analysis of the MV protein contents. The IFN-γ stimulation induced dramatic changes in the protein content of the MVs. Complement factors (C3, C4A, C5) and lipid binding proteins (i.e apolipoproteins) were only found in the MVctrls, whereas the MVstim contained tetraspanins (CD9, CD63, CD81) and more complete proteasome complex accompanied with MHCI. We further discovered that differently produced MV pools contained specific Rab proteins suggesting that same cells, depending on external signals, produce vesicles originating from different intracellular locations. Conclusions We demonstrate by both in vitro and in vivo models accompanied with a detailed analysis of molecular characteristics that inflammatory conditioning of MSCs influence on the protein content and functional properties of MVs revealing the

    The tail and paws in rodents are heat exchangers involved in the maintenance of core body temperature (T(core)). They are also the most widely used target organs to study acute or chronic "models" of pain. We describe the fluctuations of vasomotor tone in the tail and paws in conditions of thermal neutrality and the constraints of these physiological processes on the responses to thermal nociceptive stimuli, commonly used as an index of pain. Skin temperatures were recorded with a calibrated thermal camera to monitor changes of vasomotor tone in the tail and paws of awake and anesthetized rats. In thermoneutral conditions, the sympathetic tone fluctuated at a rate of two to seven cycles/h. Increased mean arterial blood pressure (MAP; ∼46 mmHg) was followed by increased heart rate (HR; ∼45 beats/min) within 30 s, vasoconstriction of extremities (3.5-7°C range) within 3-5 min, and increased T(core) (∼0.7°C) within 6 min. Decreased MAP was followed by opposite events. There was a high correlation between HR and T(core) recorded 5-6 min later. The reaction time of the animal's response to a radiant thermal stimulus-heat ramp (6°C/s, 20 mm(2) spot) generated by a CO2 laser-directed to the tail depends on these variations. Consequently, the fluctuations in tail and paw temperature thus represent a serious confound for thermal nociceptive tests, particularly when they are conducted at thermal neutrality. PMID:25008410

    Solitary cecum diverticulum is a benign formation, but it can be complicated with inflammation, perforation and bleeding. Cecum diverticulitis (CD) is the most common complication of caecal diverticulum and it has the highest incidence among Asians, but it is a rare condition in the western world. The incidence of colonic diverticular disease can vary according to national origin, cultural structure and nutritional habits. CD is not common in our country, but it is an important situation because of its clinical similarity with the commonly seen acute right side abdominal diseases like acute appendicitis. Preoperative diagnosis is difficult, and hence, the actual frequency is not known. The treatment of CD can vary from medical therapy to right hemi colectomy. In this study, we presented ten CD cases on whom surgical resection was performed in our surgery unit during the last 8 years. Our purpose was to increase the awareness of surgeons about this situation, and so, make them pay attention for not having their first experience in the operating room. PMID:27054646

    Acute pelvic pain may be the manifestation of various gynecologic and non-gynecologic disorders from less alarming rupture of the follicular cyst to life threatening conditions such as rupture of ectopic pregnancy or perforation of inflamed appendix. In order to construct an algorithm for differential diagnosis we divide acute pelvic pain into gynecologic and non-gynecologic etiology, which is than subdivided into gastrointestinal and urinary causes. Appendicitis is the most common surgical emergency and should always be considered in differential diagnosis if appendix has not been removed. Apart of clinical examination and laboratory tests, an ultrasound examination is sensitive up to 90% and specific up to 95% if graded compression technique is used. Still it is user-depended and requires considerable experience in order to perform it reliably. Meckel's diverticulitis, acute terminal ileitis, mesenteric lymphadenitis and functional bowel disease are conditions that should be differentiated from other causes of low abdominal pain by clinical presentation, laboratory and imaging tests. Dilatation of renal pelvis and ureter are typical signs of obstructive uropathy and may be efficiently detected by ultrasound. Additional thinning of renal parenchyma suggests long-term obstructive uropathy. Ruptured ectopic pregnancy, salpingitis and hemorrhagic ovarian cysts are three most commonly diagnosed gynecologic conditions presenting as an acute abdomen. Degenerating leiomyomas and adnexal torsion occur less frequently. For better systematization, gynecologic causes of acute pelvic pain could be divided into conditions with negative pregnancy test and conditions with positive pregnancy test. Pelvic inflammatory disease may be ultrasonically presented with numerous signs such as thickening of the tubal wall, incomplete septa within the dilated tube, demonstration of hyperechoic mural nodules, free fluid in the "cul-de-sac" etc. Color Doppler ultrasound contributes to more

    To improve the diagnosis of closed abdominal trauma since 1966 the authors have been widely employing laparocentesis. The results of using abdominal punctures an 260 patients are reported. The method proved to be reliable in 97.7%. The use of laparocentesis enabled the authors to reduce the number of errors by 7.3 times, to shorten the terms of establishing the diagnosis by 4 times as compared with the control group of patients (190 subjects in whom the recognition of abdominal injuries is based on common clinical symptoms).

    We report a case of combined subcutaneous, intrathoracic, and abdominal splenosis who presented with attacks of flushing, tachycardia and vague abdominal pain. The patient's past medical history included a splenectomy due to abdominal trauma and years later, a lung lobectomy due to recurrent pneumonia. An enhancing solid mass adjacent to the upper pole of the left kidney and nodular pleural based lesions in the left hemi-thorax along with nodular lesions in subcutaneous tissue of the left chest wall suggested possible adrenal malignancy with multiple metastases. Histopathologic examination demonstrated benign lesions of ectopic splenic tissue. PMID:20804314

    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.

    Given the high rate of morbidity and mortality associated with abdominal aortic aneurysms (AAAs), accurate diagnosis and preoperative evaluation are essential for improved patient outcomes. Ultrasonography is the standard method of screening and monitoring AAAs that have not ruptured. In the past, aortography was commonly used for preoperative planning in the repair of AAAs. More recently, computed tomography (CT) has largely replaced older, more invasive methods. Recent advances in CT imaging technology, such as helical CT and CT angiography, offer significant advantages over traditional CT. These methods allow for more rapid scans and can produce three-dimensional images of the AAA and important adjacent vascular structures. Use of endovascular stent grafts has increased recently and is less invasive for the repair of AAAs in selected cases. Aortography and CT angiography can precisely determine the size and surrounding anatomy of the AAA to identify appropriate candidates for the use of endovascular stent grafts. Helical CT and CT angiography represent an exciting future in the preoperative evaluation of AAAs. However, this technology is not the standard of care because of the lack of widespread availability, the cost associated with obtaining new equipment, and the lack of universal protocols necessary for acquisition and reconstruction of these images.

    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

    Aetiologic factors (gallstones, hyperlipidemia I-IV, hypertriglyceridaemia) make their occurrence, mainly, in the third trimester of gestation. Two cases of acute pancreatitis in pregnancy are described; in both cases patients referred healthy diet, no habit to smoke and no previous episode of pancreatitis. An obstructive pathology of biliary tract was the aetiologic factor. Vomiting, upper abdominal pain are aspecific symptoms that impose a differential diagnosis with acute appendicitis, cholecystitis and obstructive intestinal pathology. Laboratory data (elevated serum amylase and lipase levels) and ultrasonography carry out an accurate diagnosis. The management of acute pancreatitis is based on the use of symptomatic drugs, a low fat diet alternated to the parenteral nutrition when triglycerides levels are more than 28 mmol/L. Surgical therapy, used only in case of obstructive pathology of biliary tract, is optimally collected in the third trimester or immediately after postpartum. Our patients, treated only medically, delivered respectively at 38th and 40th week of gestation. Tempestivity of diagnosis and appropriate therapy permit to improve prognosis of a pathology that, although really associated with pregnancy, presents high maternal mortality (37%) cause of complications (shock, coagulopathy, acute respiratory insufficiency) and fetal (37.9%) by occurrence of preterm delivery.

    In Korea, the use of herbal remedies is a common cause of drug-induced liver injury. However, the occurrence of both acute pancreatitis and acute hepatitis after taking herbal remedies has rarely been reported. Herein, we report a case of concurrent acute pancreatitis and acute hepatitis associated with Ceramium kondoi ingestion. A 58-year-old woman was diagnosed with advanced gastric cancer 7 months ago. Total gastrectomy and adjuvant chemotherapy was performed without complications. The patient had been well until recently, when she presented with severe abdominal pain after ingestion of Ceramium kondoifor 4 weeks. The laboratory findings demonstrated elevated liver enzymes and lipase, and abdominal computed tomography revealed pancreas swelling with fat infiltration. The diagnosis was made based on the diagnostic criteria for drug induced pancreatitis and the Russel Uclaf Causality Assessment Method scale for drug-induced liver injury. After cessation of Ceramium kondoi, she showed clinical and biochemical improvement. PMID:24262598

We present the case of a 16-year-old Hispanic male patient, in remission induction therapy for acute lymphoblastic leukemia on treatment with mitoxantrone, vincristine, prednisone, and L-asparaginase. He was hospitalized complaining of abdominal pain, nausea, and vomiting. Hyperglycemia, acidosis, ketonuria, low bicarbonate levels, hyperamylasemia, and hyperlipasemia were documented, and the diagnosis of diabetic ketoacidosis was made. Because of uncertainty of the additional diagnosis of acute pancreatitis as the cause of abdominal pain, a contrast-enhanced computed tomography was performed resulting in a Balthazar C pancreatitis classification.

    Acute hollow organ ischemia commonly presents with acute pain prompting radiologic evaluation and almost always requires urgent treatment. Despite different risk factors and anatomic differences, ischemia is commonly due to low flow states but can also be due to arterial and venous occlusion. Radiologic diagnosis is critical as many present with nonspecific symptoms. Contrast-enhanced computed tomography (CT) is the modality of choice. Magnetic resonance imaging (MRI) is preferred in suspected appendicitis in pregnant patients and is superior in biliary necrosis. This article provides a pictorial review of the CT/MRI features of hollow abdominal organ ischemia while highlighting key clinical features, pathogenesis, and management. PMID:27317221

    Introduction Internal hernia is a pathological condition resulting from abnormal protrusion of abdominal viscera through an opening in the intraperitoneal recesses of the abdominal cavity. Small bowel obstruction due to internal hernia is not common (0.25–0.9% of cases). The most common group is that of paraduodenal hernias (53%), of which the left-sided one is the most common type (75%). Presentation of case We report a case of a 43 year-old man with a history of recurrent abdominal pain, who was hospitalized because of an episode of acute small bowel obstruction. He had no previous surgery. Computed tomography revealed an encapsulated circumscribed cluster of jejunal loops in the left upper quadrant, near the ligament of Treitz, and the hernia orifice was adjacent to the left side of the inferior mesenteric vessels. Emergency laparoscopic surgery was performed: the small bowel was found completely herniated under the inferior mesenteric vessels. It was gradually reduced and the hernia space was closed with a running suture. The patient was discharged on the fourth day without complications. Conclusion Left paraduodenal hernia is a rare cause of small bowel obstruction that should be taken into account in a patient with a history of recurrent abdominal pain or intestinal obstruction, and no previous surgery. Computed tomography is the standard for a correct diagnosis. Surgery is treatment of choice, because it reduces the risk of emergency and complications associated to hernia. Laparoscopic approach is feasible and effective, also in emergency situation. PMID:26826933

    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.

    Acute otitis media is a common infection in children. Most acute otitis media episodes can be treated at an outpatient setting with antimicrobials, or only expectant observation. Hospital treatment with parenteral medication, and myringotomy or tympanostomy, may be needed to treat those with severe, prolonged symptoms, or with complications. The most common intratemporal complication of acute otitis media is acute mastoiditis. If a child with acute mastoiditis does not respond to this treatment, or if complications develop, further examinations and other surgical procedures, including mastoidectomy, are considered. Since the treatment of complicated acute otitis media and complicated acute mastoiditis differs, it is important to differentiate these two conditions. This article focuses on the differential diagnostics of acute otitis media and acute mastoiditis in children. PMID:27613655

    Septic arthritis of the pubic symphysis is a rare infection mostly caused by Staphylococcus aureus, and is traditionally associated with risk factors (sports, female incontinence surgery). Typical features of pubic symphysis infection include abdominal, pelvic, or groin pain that increases upon standing and walking, causing limping to occur. Acute onset of fever is often associated. It is important to distinguish septic arthritis of the pubic symphysis from its aseptic homologue, improperly called 'osteitis pubis' in English literature. This general term is mostly used to designate a mechanical pubic pain and has several aetiological meanings (joint stress, postoperative pain, rheumatic diseases). However, some authors consider the infection of the pubic symphysis as a variant of osteitis pubis, placing the two diseases in the continuum of the same entity. This confusion in pubic pathology related to its rarity and its atypical presentation, may in some cases lead to diagnostic and therapeutic delay. In this article, we would like to make practitioners aware of this uncommon and often ignored anatomical site, so that it can recover its place in the differential diagnosis of abdominal pain.

    Abdominal pain is a commonplace reason for surgical consultation in the emergency department and is the the most common symptom which the digestive surgeon on-call must evaluate. He must understand the pathophysiologic basis of visceral pain and referred pain in order to appreciate its diverse manifestations. Abdominal pain can stem from many causes intestinal and non-intestinal, medical and surgical. Evaluation and management in the emergency department must be rapid and pragmatic; clinical history and physical examination should define the gravity of the case, direct the first diagnostic procedures and complementary examinations, and guide the therapeutic direction. Ultrasonography is a quick and effective diagnostic procedure in the diagnosis of biliary, urologic, and gynecologic pathologies; it can be useful for other digestive problems as well. The new generation spiral CT scanner gives excellent definition of digestive and vascular pathologies. The initial evaluation and management of the acute abdomen may determine the prognosis of the patient; it should lead to prompt symptomatic relief and to a well-directed treatment appropriate to the diagnosis.

    Abdominal aortic aneurysms (AAAs), which commonly occur among elderly individuals, are accompanied by a risk of rupture and subsequent high mortality. Establishment of medical therapies for the prevention of AAAs requires further understanding of the molecular pathogenesis of this condition. This report details the possible involvement of Osteoprotegerin (OPG) in the prevention of AAAs through inhibition of Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL). In CaCl2-induced AAA models, both internal and external diameters were significantly increased with destruction of elastic fibers in the media in Opg knockout (KO) mice, as compared to wild-type mice. Moreover, up-regulation of TRAIL expression was observed in the media by immunohistochemical analyses. Using a culture system, both the TRAIL-induced expression of matrix metalloproteinase-9 in smooth muscle cells (SMCs) and the chemoattractive effect of TRAIL on SMCs were inhibited by OPG. These data suggest that Opg may play a preventive role in the development of AAA through its antagonistic effect on Trail. PMID:26783750

    Steady flow in abdominal aortic aneurysm models has been examined for four aneurysm sizes over Reynolds numbers from 500 to 2600. The Reynolds number is based on entrance tube diameter, and the inlet condition is fully developed flow. Experimental and numerical methods have been used to determine: (i) the overall features of the flow, (ii) the stresses on the aneurysm walls in laminar flow, and (iii) the onset and characteristics of turbulent flow. The laminar flow field is characterized by a jet of fluid (passing directly through the aneurysm) surrounded by a recirculating vortex. The wall shear stress magnitude in the recirculation zone is about ten times less than in the entrance tube. Both wall shear stress and wall normal stress profiles exhibit large magnitude peaks near the reattachment point at the distal end of the aneurysm. The onset of turbulence in the model is intermittent for 2000 < Re < 2500. The results demonstrate that a slug of turbulence in the entrance tube grows much more rapidly in the aneurysm than in a corresponding length of uniform cross section pipe. When turbulence is present in the aneurysm the recirculation zone breaks down and the wall shear stress returns to a magnitude comparable to that in the entrance tube. PMID:8309237

    In cases of acute fatal child abuse, certain injuries, including cutaneous blunt force trauma, skull fractures, subdural hematomas, intra-abdominal hemorrhage, and retinal hemorrhages are common and well described in the pediatric and forensic literature. These gross findings at autopsy, when taken into consideration with scene investigation and interviews with caregivers, may indicate both a clear manner and cause of death. In such cases, the discovery of additional pathologic changes attributable to older abusive injuries helps support a conclusion of death due to inflicted trauma. We discuss four cases of fatal child abuse in which acute blunt force abdominal trauma was the cause of death. In each of these cases, careful examination with proper sectioning and microscopy of select abdominal tissues revealed that the acute tissue trauma was superimposed on a background of older, healing injury. This older trauma was characterized by classic histologic elements of tissue repair, including fibroblast proliferation, early scar formation, increased vascularity, and hemosiderin-laden macrophages. Iron and trichrome stains were used to confirm the presence of hemosiderin and fibrosis in all four cases, but the recognition of fibroblast proliferation and a reactive vascular pattern was best seen on routine hematoxylin and eosin stains. The gross and microscopic autopsy findings, along with available investigative information, established the diagnosis of chronic physical abuse. PMID:18808370

    Excess fat in the abdomen can be classified generally as visceral and subcutaneous adiposity. Evidence suggests that visceral adiposity has greater implications for diabetes than other fat depots. The purpose of this study is to explore the disparities in the distribution of abdominal adiposity in diabetic/prediabetic and nondiabetic populations and to identify moderators that influence the pattern of central obesity via a meta-analysis technique. The Hedges' g was used as a measure of effect size and 95% confidence interval was computed. A total of 41 relevant studies with 101 effect sizes were retrieved. Pooled effect sizes for visceral and subcutaneous adiposity were 0.69 and 0.42, respectively. Diabetic/prediabetic populations exhibited greater visceral and subcutaneous adiposity compared to nondiabetic populations (Z = 10.35, P < 0.05). Significant moderator effects of gender (Z = −2.90) and assessment method of abdominal adiposity (Z = −2.17) were found for visceral fat (P < 0.05), but not for subcutaneous fat. Type of health condition influenced both visceral (Z = −5.10) and subcutaneous (Z = −7.09) abdominal adiposity volumes (P < 0.05). Abdominal adiposity distributions were significantly altered in the diabetic/prediabetic population compared to the nondiabetic population. Gender, assessment method of abdominal adiposity, and type of health conditions (diabetic/prediabetics) were identified as crucial moderators that influence the degree of abdominal adiposity.

First, the patient presented to a regional hospital reporting abdominal pain, vomiting and liquid stool. She was admitted with the diagnosis of acute surgical abdomen and underwent surgery. Upon admission in our department, laboratory findings showed high values for total lipids = 2600 mg/dL and triglycerides 1200 mg/dL. Abdominal ultrasound revealed a pancreas with a small enlargement of the head (19 mm), and with a heterogeneous structure of the parenchyma. Abdominal computed tomography showed small left pleural collection and a high-dimensioned pancreas, particularly at the head, with heterogeneous structure, and peripancreatic collections. The patient was treated by fasting, gastric decompression by nasogastric tube, and intravenous antibiotherapy followed by antialgic and antispasticity treatment. Time of the patient’s first feeding was after the 7th day of hospitalization. The patient was discharged in a very good condition after 22 days of hospitalization. PMID:23599811

Conventional investigations and treatments failed to prove and improve her condition. ERCP was done on the twelfth day after admission. 3 caudal ends of living round worms were noted protruding from the papillary orifice during endoscopy. Cholangiography revealed impacted multiple round worms in the common bile duct and both intrahepatic ducts. Endoscopic extraction of the worms was done by using dormia basket and removed with endoscope. Repeated procedure was done 21 times in two and a half hours, obtaining 26 live, mature Ascaris lumbricoides varying from 13 to 24 cm in length. Repeated cholangiogram confirmed complete removal of the worms. The patient was relieved from abdominal pain immediately after the procedure, and given oral albendazole 400 mg daily for 7 days. She was discharged asymptomatic 8 days after Ascaris removal. PMID:10443103

    OBJECTIVE: Patients undergoing abdominal surgery are at risk for pulmonary complications. The principal cause of postoperative pulmonary complications is a significant reduction in pulmonary volumes (FEV1 and FVC) to approximately 65-70% of the predicted value. Another frequent occurrence after abdominal surgery is increased intra-abdominal pressure. The aim of this study was to correlate changes in pulmonary volumes with the values of intra-abdominal pressure after abdominal surgery, according to the surgical incision in the abdomen (superior or inferior). METHODS: We prospectively evaluated 60 patients who underwent elective open abdominal surgery with a surgical time greater than 240 minutes. Patients were evaluated before surgery and on the 3rd postoperative day. Spirometry was assessed by maximal respiratory maneuvers and flow-volume curves. Intra-abdominal pressure was measured in the postoperative period using the bladder technique. RESULTS: The mean age of the patients was 56±13 years, and 41.6% 25 were female; 50 patients (83.3%) had malignant disease. The patients were divided into two groups according to the surgical incision (superior or inferior). The lung volumes in the preoperative period showed no abnormalities. After surgery, there was a significant reduction in both FEV1 (1.6±0.6 L) and FVC (2.0±0.7 L) with maintenance of FEV1/FVC of 0.8±0.2 in both groups. The maximum intra-abdominal pressure values were similar (p = 0.59) for the two groups. There was no association between pulmonary volumes and intra-abdominal pressure measured in any of the groups analyzed. CONCLUSIONS: Our results show that superior and inferior abdominal surgery determines hypoventilation, unrelated to increased intra-abdominal pressure. Patients at high risk of pulmonary complications should receive respiratory care even if undergoing inferior abdominal surgery. PMID:25029580

    OBJECTIVE Automated analysis of abdominal CT has advanced markedly over just the last few years. Fully automated assessment of organs, lymph nodes, adipose tissue, muscle, bowel, spine, and tumors are some examples where tremendous progress has been made. Computer-aided detection of lesions has also improved dramatically. CONCLUSION This article reviews the progress and provides insights into what is in store in the near future for automated analysis for abdominal CT, ultimately leading to fully automated interpretation.

    This article describes the introduction of abdominal massage techniques by a community team as part of a total bowel management programme for people with learning disabilities. A trust-wide audit of prescribed laxative use by this client group raised concerns, and led to a more systematic approach to managing constipation in people with learning disabilities. An education programme for carers proved to be successful. Some reported that adopting abdominal massage provided further opportunity to develop the therapeutic relationship. PMID:25005415

    A traumatic pseudoaneurysm of the abdominal aorta is a rare entity, occurring as the result of a missed aortic lesion at the time of the initial injury. Therefore, clinical suspicion and careful abdominal exploration at first laparotomy is mandatory to prevent aortic pseudoaneurysm formation and its risk of delayed rupture. We present a case of successful surgical treatment of a suprarenal aortic false aneurysm, presenting 4 weeks after a life-threatening gunshot wound in a 13-year-old child. PMID:10499389

    Acute cholecystitis can develop without gallstones in critically ill or injured patients. However, the development of acute acalculous cholecystitis is not limited to surgical or injured patients, or even to the intensive care unit. Diabetes, malignant disease, abdominal vasculitis, congestive heart failure, cholesterol embolization, and shock or cardiac arrest have been associated with acute acalculous cholecystitis. Children may also be affected, especially after a viral illness. The pathogenesis of acute acalculous cholecystitis is a paradigm of complexity. Ischemia and reperfusion injury, or the effects of eicosanoid proinflammatory mediators, appear to be the central mechanisms, but bile stasis, opioid therapy, positive-pressure ventilation, and total parenteral nutrition have all been implicated. Ultrasound of the gallbladder is the most accurate diagnostic modality in the critically ill patient, with gallbladder wall thickness of 3.5 mm or greater and pericholecystic fluid being the two most reliable criteria. The historical treatment of choice for acute acalculous cholecystitis has been cholecystectomy, but percutaneous cholecystostomy is now the mainstay of therapy, controlling the disease in about 85% of patients. Rapid improvement can be expected when the procedure is performed properly. The mortality rates (historically about 30%) for percutaneous and open cholecystostomy appear to be similar, reflecting the severity of illness, but improved resuscitation and critical care may portend a decreased risk of death. Interval cholecystectomy is usually not indicated after acute acalculous cholecystitis in survivors; if the absence of gallstones is confirmed and the precipitating disorder has been controlled, the cholecystostomy tube can be pulled out after the patient has recovered.

    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

    Previous studies have repeatedly reported that increasing age is a significant risk factor for worse outcomes after allogeneic hematopoietic stem cell transplantation (allo-HSCT) among patients with acute myeloid leukemia (AML). However, more recent studies reported conflicting results regarding the association between age and outcomes in elderly patients. Therefore, we conducted a large-scale, nationwide retrospective study to examine the impact of age on outcomes of allo-HSCT with reduced intensity conditioning (RIC) for AML patients who were older than 50 years. Of the 757 patients, 89 patients (11.8%) were 50-54, 249 patients (32.9%) were 55-59, 301 patients (39.8%) were 60-64 and 118 patients (15.6%) were ≥65 years old. The 3-year overall survival (OS) (47.8, 45.2, 37.9, and 36.6% for patients aged 50-54, 55-59, 60-64, and ≥65 years, respectively, P = 0.24) and nonrelapse mortality (NRM) (24.0, 22.8, 29.2, and 27.6% for patients aged 50-54, 55-59, 60-64, and ≥65 years, respectively, P = 0.49) were not significantly different among the four age groups. Multivariate analysis revealed that increased age had no significant effect on OS or NRM after adjusting for covariates. These results suggested that advanced patient age is not a contraindication for RIC allo-HSCT in elderly AML patients. PMID:26663096

    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.

    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.

    2010-01-01

    Abdominal aortic aneurysm (AAA) is a multifactorial disease with a strong genetic component. Since first candidate gene studies were published 20 years ago, nearly 100 genetic association studies using single nucleotide polymorphisms (SNPs) in biologically relevant genes have been reported on AAA. The studies investigated SNPs in genes of the extracellular matrix, the cardiovascular system, the immune system, and signaling pathways. Very few studies were large enough to draw firm conclusions and very few results could be replicated in another sample set. The more recent unbiased approaches are family-based DNA linkage studies and genome-wide genetic association studies, which have the potential of identifying the genetic basis for AAA, if appropriately powered and well-characterized large AAA cohorts are used. SNPs associated with AAA have already been identified in these large multicenter studies. One significant association was of a variant in a gene called CNTN3 which is located on chromosome 3p12.3. Two follow-up studies, however, could not replicate the association. Two other SNPs, which are located on chromosome 9p21 and 9q33 were replicated in other samples. The two genes with the strongest supporting evidence of contribution to the genetic risk for AAA are the CDKN2BAS gene, also known as ANRIL, which encodes an antisense RNA that regulates expression of the cyclin-dependent kinase inhibitors CDKN2A and CDKN2B, and DAB2IP, which encodes an inhibitor of cell growth and survival. Functional studies are now needed to establish the mechanisms by which these genes contribute to AAA pathogenesis. PMID:21146954

    Takayasu’s arteritis affects most commonly young women, often causing stenotic and occasionally dilated lesions of the medium-to-large-sized arteries with an acute inflammatory signs and symptoms. Here, we report a rare case of Takayasu’s arteritis with total occlusion of the abdominal aorta, which was successfully treated with medication alone and asymptomatic over 40 years. Magnetic resonance imaging revealed total occlusion of the abdominal aorta and stenosis of the right carotid artery. This is the first report of a very rare case of Takayasu’s arteritis, in which medical treatment only was successful against total occlusion of the abdominal aorta. PMID:26131036

    Pathologic splenic rupture is a rare and life-threatening complication of acute leukemia. It is even more uncommon as the initial manifestation, and only a few cases has been reported in the literature. Early recognition of this complication is vital because the prognosis is fatal without immediate treatment by splenectomy. We report the case of a spontaneous spleen rupture irreversibly complicating the onset of acute lymphoblastic leukemia in a 19-year-old man, in spite of splenectomy. In our case abdominal ultrasound was a good, non-invasive diagnostic test. Therefore, we believe that the course of the underlying disease and the physical condition of the patient dramatically influenced the disease evolution. PMID:9793269

    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.

    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

    We examined the efficacy of reduced-intensity conditioning (RIC) and compared outcomes of 93 patients older than 16 years after RIC with 1428 patients receiving full-intensity conditioning for allografts using sibling and unrelated donors for Philadelphia-negative acute lymphoblastic leukemia (ALL) in first or second complete remission. RIC conditioning included busulfan 9 mg/kg or less (27), melphalan 150 mg/m2 or less (23), low-dose total body irradiation (TBI; 36), and others (7). The RIC group was older (median 45 vs 28 years, P < .001) and more received peripheral blood grafts (73% vs 43%, P < .001) but had similar other prognostic factors. The RIC versus full-intensity conditioning groups had slightly, but not significantly, less acute grade II-IV graft-versus-host disease (39% vs 46%) and chronic graft-versus-host disease (34% vs 42%), yet similar transplantation-related mortality. RIC led to slightly more relapse (35% vs 26%, P = .08) yet similar age-adjusted survival (38% vs 43%, P = .39). Multivariate analysis showed that conditioning intensity did not affect transplantation-related mortality (P = .92) or relapse risk (P = .14). Multivariate analysis demonstrated significantly improved overall survival with: Karnofsky performance status more than 80, first complete remission, lower white blood count, well-matched unrelated or sibling donors, transplantation since 2001, age younger than 30 years, and conditioning with TBI, but no independent impact of conditioning intensity. RIC merits further investigation in prospective trials of adult ALL. PMID:20404137

    Postherpetic pseudohernia causes an abdominal bulge as well as an abdominal wall herniation. This disease is one of the neurological complications of herpes zoster and essentially consists of paresis of ipsilateral abdominal muscles. Postherpetic pseudohernia may be mistaken for abdominal wall herniation because it is not well known. We describe two cases presenting an abdominal bulge. The ipsilateral abdominal bulge appeared after recovery from abdominal zoster. Abdominal CT showed no evidence of a herniation or mass. We diagnosed a postherpetic pseudohernia. One of the patients recovered spontaneously 4 months after the onset, and the other partially recovered after 2 months. This disease can be expected to disappear spontaneously, unlike abdominal herniation requiring surgery. It has been reported that 79.3% of patients eventually recovered spontaneously. For surgeons and general practitioners, it is beneficial to keep this disease in mind when examining a patient presenting an abdominal bulge. PMID:27229900

    2016-03-01

    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.

    Postoperative cognitive dysfunction (POCD) is a debilitating surgical complication, with cardiac surgery patients at particular risk. To gain insight in the mechanisms underlying the higher incidence of POCD after cardiac versus non-cardiac surgery, systemic and central inflammatory changes, alterations in intraneuronal pathways, and cognitive performance were studied after cardiac and abdominal surgery in rats. Male Wistar rats were subjected to ischemia reperfusion of the upper mesenteric artery (abdominal surgery) or the left coronary artery (cardiac surgery). Control rats remained naïve, received anesthesia only, or received thoracic sham surgery. Rats were subjected to affective and cognitive behavioral tests in postoperative week 2. Plasma concentrations of inflammatory factors, and markers for neuroinflammation (NGAL and microglial activity) and the BDNF pathway (BDNF, p38MAPK and DCX) were determined. Spatial memory was impaired after both abdominal and cardiac surgery, but only cardiac surgery impaired spatial learning and object recognition. While all surgical procedures elicited a pronounced acute systemic inflammatory response, NGAL and TNFα levels were particularly increased after abdominal surgery. Conversely, NGAL in plasma and the paraventricular nucleus of the hypothalamus and microglial activity in hippocampus and prefrontal cortex on postoperative day 14 were increased after cardiac, but not abdominal surgery. Both surgery types induced hippocampal alterations in BDNF signaling. These results suggest that POCD after cardiac surgery, compared to non-cardiac surgery, affects different cognitive domains and hence may be more extended rather than more severe. Moreover, while abdominal surgery effects seem limited to hippocampal brain regions, cardiac surgery seems associated with more wide spread alterations in the brain. PMID:26867718

    1999-01-01

    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.

    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

    The potential involvement of the endocrine/paracrine mechanisms in the mesenchymal stromal cells (MSCs) therapy for acute kidney injury (AKI) has been increasingly studied. The aim of the present meta-analysis was to systematically review the therapeutic role of MSC-conditioned medium (CM) or MSCs released by extracellular vesicles (Evs) for the treatment of AKI in rodent models. Studies were identified using PubMed and Scopus databases using a custom search strategy and eligibility criteria. Data regarding serum creatinine (SCr) concentration, CM or Evs, measurement time point, AKI model (toxic or non-toxic) and other parameters, including delivery route, animal type and animal numbers, were extracted. Pooled analysis and subgroup analysis as well as multivariable meta-regression were performed. Heterogeneity and publication bias were also investigated. A total of 13 studies were included and analyzed. Pooled analysis showed reduced SCr (0.93 [0.67, 1.20], mg/dl) in rodent models of AKI after CM/Evs therapy. The results of the subgroup analysis suggested that Evs induced an increased therapeutic effect, in the form of SCr reduction, as compared with CM (P=0.05). There were also other significant influential factors for SCr reduction including measurement time point (P=0.0004) and therapeutic time point (P<0.0001) after surgery. By contrast, parameters such as delivery route, injury type and cell type were not significant influential factors. Multivariable meta-regression analysis showed that measurement time point (P=0.041), therapeutic time point (P=0.03), Evs or CM (P=0.0003) and cell type (P<0.0001) were influential factors in the reduction of SCr. The present meta-analysis indicates that CM or Evs derived from MSCs are able to improve the impaired renal function in rodents modelling AKI. Compared with CM, Evs may produce a more marked therapeutic effect in recovery from renal failure. In addition, CM or Evs administration in early stages of AKI may result in

    Acute porphyrias are often misdiagnosed and most commonly present as atypical neuropsychiatric symptoms or acute abdominal pain. Clinicians should suspect acute porphyrias in patients presenting with variable neuropsychiatric symptoms and unexplained pain. Proper identification can lead to less iatrogenicity associated with porphyrinogenic agents, appropriate management, and a better patient outcome. The case of a patient with hereditary coproporphyria, one of the acute porphyrias, is presented to illustrate the broad manifestations, unsuspected diagnosis, and difficulties in management.

    Abdominal crises are common in critically ill patients who are admitted to the intensive care unit for problems unrelated to the abdomen. General surgeons may be asked to assess these patients for such reasons as pain, distension, possible sepsis, radiologic or laboratory abnormalities. Since many of the diagnostic signs and symptoms of acute abdomen are blunted or absent in critically ill patients who may be comatose or have been given analgesics or steroids, frequent thorough physical examination and close cooperation with the service admitting the patient are necessary to ensure early diagnosis and aggressive treatment of the abdominal crisis.

    Systemic lupus erythematosus (SLE) is an autoimmune disease characterized with multiple organ involvements. Acute acalculous cholecystitis(AAC) is an extremely rare manifestation of digestive system involvement in SLE. We reported a case of 32-year-old woman who complained skin rashes for two weeks and stomachache and oliguria for one day. She had rashes at onset, and developed fever, stomachache, hypotension and headache. Physical examination at admission indicated blood pressure 76/47 mmHg(1 mmHg=0.133 kPa), heart rate 107 beats/min, warm acra. Murphy's sign was positive. Ultrasound suggested the enlarged gallbladder with surrounding hypoecho band yet no biliary calculi were found. A diagnosis of SLE was made, characteristic with distributive shock at the onset and AAC, complicated with neuropsychiatric lupus and lupus nephritis. She had an acute and severe course of disease, which had been relieved after treatment of high dose glucocorticoid and immunosuppressants. This case arouses clinicians to pay more attention to AAC as a rare form of disease flare in SLE. Early diagnosis of AAC is crucial to a favorable prognosis and in avoid of abdominal surgery.

    This paper investigates the effect of developing arterial blockage at the abdominal aorta on the blood pressure waves at an externally accessible location suitable for invasive measurements such as the brachial and the femoral arteries. Arterial blockages are created surgically within the abdominal aorta of healthy Wistar rats to create narrowing resemblance conditions. Blood pressure is measured using a catheter inserted into the right femoral artery. Measurements are taken at the baseline healthy condition as well as at four different severities (20, 50, 80 and 100 %) of arterial blockage. In vivo and in vitro measurements of the lumen diameter and wall thickness are taken using magnetic resonance imaging and microscopic techniques, respectively. These data are used to validate a 3D computational fluid dynamics model which is developed to generalize the outcomes of this work and to determine the arterial stress and strain under the blockage conditions. This work indicates that an arterial blockage in excess of 20 % of the lumen diameter significantly influences the pressure wave and reduces the systolic blood pressure at the right femoral artery. High wall shear stresses and low circumferential strains are also generated at the blockage site. PMID:26319006

    A 5-year-old Quarter Horse mare was examined because of lethargy, fever, and weight loss of 1 month's duration. Thoracic auscultation revealed decreased lung sounds cranioventrally. Thoracic ultrasonography revealed bilateral anechoic areas with hyperechoic strands, consistent with pleural effusion and fibrin tags. A large amount of free fluid was evident during abdominal ultrasonography. Abnormalities included anemia, hyperproteinemia, hyperglobulinemia, hyperfibrinogenemia, and hypoalbuminemia. Thoracic radiography revealed alveolar infiltrates in the cranial and caudoventral lung fields. A cavitary mass, consistent with an abscess, could be seen caudodorsal to the crura of the diaphragm. Ultrasonographic evaluation of this area revealed a hypoechoic mass with septations. Bilateral thoracocentesis was performed. Bacterial culture of the pleural fluid did not yield growth, but Blastomyces dermatitidis was isolated from pleural fluid, abdominal fluid, and an aspirate of the abscess. The mare was euthanatized, and a diagnosis of thoracic and abdominal blastomycosis was confirmed at necropsy. PMID:10319179

    Splenosis is defined as the heterotopic autotransplantation of splenic tissue because of a ruptured spleen due to trauma or surgery. It is a benign and incidental finding, although imaging tests may sometimes orient toward malignancy simulating renal tumors, abdominal lymphomas, endometriosis, among other. We report the case of a 42-year old male in whom a MRI was performed after a study due to abdominal pain. Multiple enlarged lymph nodes were observed in the abdomen, suggestive of lymphoproliferative disease. As an important background, splenectomy was carried out due to abdominal trauma at age 9. After several studies, it was decided to perform a (99m)Tc-labeled heat-damaged red blood cell scintigraphy that showed multiple pathological deposits distributed throughout the abdomen, and even the pelvis, being consistent with splenosis.

    Mesh materials have undergone a considerable evolution over the last several decades. There has been enhancement of biomechanical properties, improvement in manufacturing processes, and development of antiadhesive laminate synthetic meshes. The evolution of bioprosthetic mesh materials has markedly changed our indications and methods for complex abdominal wall reconstruction. The authors review the optimal properties of bioprosthetic mesh materials, their evolution over time, and their indications for use. The techniques to optimize outcomes are described using bioprosthetic mesh for complex abdominal wall reconstruction. Bioprosthetic mesh materials clearly have certain advantages over other implantable mesh materials in select indications. Appropriate patient selection and surgical technique are critical to the successful use of bioprosthetic materials for abdominal wall repair. PMID:23372454

    Reconstruction of complex defects of the anterior abdomen is both challenging and technically demanding for reconstructive surgeons. Advancements in the use of pedicle and free tissue transfer along with the use of bioprosthetic and synthetic meshes have provided for novel approaches to these complex defects. Accordingly, detailed knowledge of abdominal wall and lower extremity anatomy in combination with insight into the design, implementation, and limitations of various flaps is essential to solve these complex clinical problems. Although these defects can be attributed to a myriad of etiologic factors, the objectives in abdominal wall reconstruction are consistent and include the restoration of abdominal wall integrity, protection of intraabdominal viscera, and the prevention of herniation. In this article, the authors review pertinent anatomy and the various local, regional, and distant flaps that can be utilized in the reconstruction of these complex clinical cases of the anterior abdomen.

    Abdominal pain is a very common pediatric complaint. In the majority of cases there is no life-threatening pathology behind this symptom, but a functional disease. However, all-day activities of children and adolescents are often limited, frequent absences from school, and general physician/ pediatrician office visits with often unnecessary diagnostic and therapies are registered. Once an organic etiology of the abdominal pain is excluded by a thoroughly medical history taking and physical examination, the first steps for a successful alleviation of the pain is the reassurance of the patients and their family that there is no life-threatening pathology. There is evidence that cognitive-behavioral therapy may be useful in improving pain and disability outcome in the short term. There is no evidence for pharmacological, dietetic, or complementary intervention in the treatment of chronic functional abdominal pain. PMID:27120211

    Abbreviated laparotomy is a recent technique for management of patients with severe abdominal trauma. It is based on a unified approach taking into account the overall extent of injury and the victim's physiologic potential to respond to hemorrhage. It is the first step in a multi-modal strategy. The second step is the critical care phase. The third step consists of "second-look" laparotomy that should ideally be performed on an elective basis within 48 hours and is aimed at definitive treatment of lesions. The goal of abbreviated laparotomy is damage control using temporary quick-fix procedures limited to conspicuous lesions and rapid hemostasis and/or viscerostasis procedures so that the patient can survive the acute critical period. Tension-free closure of the abdominal wall, if necessary using laparostomy, is essential to avoid abdominal compartment syndrome. With reported survival rates of about 50% in Europe and the United States, this simple life-saving technique that requires limited resources should be introduced in Africa where severe abdominal trauma often involves young patients.

    This paper reports the result of the MEDAN project that analyzes a multicenter septic shock patient data collection. The mortality prognosis based on 4 scores that are often used is compared with the prognosis of a trained neural network. We built an alarm system using the network classification results. Method. We analyzed the data of 382 patients with abdominal septic shock who were admitted to the intensive care unit (ICU) from 1998 to 2002. The analysis includes the calculation of daily sepsis-related organ failure assessment (SOFA), Acute Physiological and Chronic Health Evaluation (APACHE) II, simplified acute physiology score (SAPS) II, multiple-organ dysfunction score (MODS) scores for each patient and the training and testing of an appropriate neural network. Results. For our patients with abdominal septic shock, the analysis shows that it is not possible to predict their individual fate correctly on the day of admission to the ICU on the basis of any current score. However, when the trained network computes a score value below the threshold during the ICU stay, there is a high probability that the patient will die within 3 days. The trained neural network obtains the same outcome prediction performance as the best score, the SOFA score, using narrower confidence intervals and considering three variables only: systolic blood pressure, diastolic blood pressure and the number of thrombocytes. We conclude that the currently best available score for abdominal septic shock may be replaced by the output of a trained neural network with only 3 input variables. PMID:21262751

    AIM: To investigate the role of laparoscopy in diagnosis and treatment of intra abdominal infections. METHODS: A systematic review of the literature was performed including studies where intra abdominal infections were treated laparoscopically. RESULTS: Early laparoscopic approaches have become the standard surgical technique for treating acute cholecystitis. The laparoscopic appendectomy has been demonstrated to be superior to open surgery in acute appendicitis. In the event of diverticulitis, laparoscopic resections have proven to be safe and effective procedures for experienced laparoscopic surgeons and may be performed without adversely affecting morbidity and mortality rates. However laparoscopic resection has not been accepted by the medical community as the primary treatment of choice. In high-risk patients, laparoscopic approach may be used for exploration or peritoneal lavage and drainage. The successful laparoscopic repair of perforated peptic ulcers for experienced surgeons, is demonstrated to be safe and effective. Regarding small bowel perforations, comparative studies contrasting open and laparoscopic surgeries have not yet been conducted. Successful laparoscopic resections addressing iatrogenic colonic perforation have been reported despite a lack of literature-based evidence supporting such procedures. In post-operative infections, laparoscopic approaches may be useful in preventing diagnostic delay and controlling the source. CONCLUSION: Laparoscopy has a good diagnostic accuracy and enables to better identify the causative pathology; laparoscopy may be recommended for the treatment of many intra-abdominal infections.

    Abdominal migraine is a rarely recognized functional intestinal disorder, manifesting as recurrent paroxysmal abdominal pain of neurogenic origin. The authors describe the 9-years old girl referred to the hospital because of chronic paroxysmal abdominal pain. She did not improve after medication used commonly in functional abdominal disorders (drotaverine, mebeverine, trimebutine). On the ground of various investigations organic causes of abdominal pain were excluded. Carefully completed anamnesis, as well as precise description of the clinical picture of abdominal pain attacks, has lead to the diagnosis of abdominal migraine. According to advice of neurologist the treatment with amitriptyline was introduced. Thereafter a significant improvement was observed. Abdominal migraine has to be taken in to account when diagnosing chronic abdominal pain in children. PMID:16245431

    Acute intermittent porphyria (AIP) is a congenital disease which as its name suggests, runs intermittently. Biochemically it is characterised by over-production of hepatic ALA synthetase (ALA-s), inducible mitochondrial enzyme and an increase in prophyrinic precursors (PBG, ac S-ALA). Clinically it is characterised by an abdominal nervous symptomatology. The primary metabolic error has been identified as a deficiency in enzyme activity which partially blocks haem biosynthesis. During the appearance of clinical manifestations, certain factors are present which have the capacity of inducing hepatic ALA-s production in vitro. Apart from some preventive measures treatment is mainly of symptomatology and complications. More recently the use of ALA-s inhibitors has been introduced. PMID:6657112

    The objective of this review is to assess the incidence of postoperative acute renal failure that necessitates the application of hemofiltration and to determine the factors that influence the outcome in patients undergoing surgical repair of abdominal aortic aneurysm. In addition, the review aims to assess the outcomes of postoperative early hemofiltration as compared to late intensive hemofiltration. Different forms of renal replacement therapies for use in abdominal aortic aneurysm surgery patients are discussed. Electronic literature searches were performed using Pubmed, Medline, Embase, Sumsearch, Cinahil, The Cochrane Central Register of Controlled Trials and Excerpta Medica. The search identified 419 potentially eligible studies, of which 119 were excluded based on the title and abstract. Of the remaining 300 studies, full articles were collected and re-evaluated. Forty-five articles satisfied our inclusion criteria, of which only 12 were of the IA Level of evidence. The search results indicated that the underlying disease, its severity and stage, the etiology of acute renal failure, clinical and hemodynamic status of the patient, the resources available, and different costs of therapy might all influence the choice of the renal replacement therapy strategy. However, clear guidelines on renal replacement therapy duration are still lacking. Moreover, it is not known whether in acute renal failure patients undergoing abdominal aortic aneurysm surgery, renal replacement therapy modalities can eliminate significant amounts of clinically relevant inflammatory mediators. This review gives current information available in the literature on the possible mechanisms underlying acute renal failure and recent developments in continuous renal replacement treatment modalities.

    Radionuclide hepatobiliary imaging with Tc-99m IDA is a useful procedure for the diagnosis of acute cholecystitis. Visualization of the gallbladder essentially rules out acute cholecystitis. Nonvisualization suggest acute cholecystitis but may also be associated with chronic gallbladder disease or other conditions. The authors recently observed five patients in whom a rim of increased parenchymal liver activity was seen adjacent to the gallbladder fossa. All five patients had acute gangrenous cholecystitis. The rim of increased activity appears to be a useful secondary sign of acute cholecystitis.

    Pregabalin is thought to exert its therapeutic effect in neuropathic pain via binding to α2δ-1 subunits of voltage-gated calcium (Ca(2+)) channels. However, the exact analgesic mechanism after its binding to α2δ-1 subunits remains largely unknown. Whether a clinical concentration of pregabalin (≈10μM) can cause acute inhibition of dorsal horn neurons in the spinal cord is controversial. To address this issue, we undertook intracellular Ca(2+)-imaging studies using spinal cord slices with an intact attached L5 dorsal root, and examined if pregabalin acutely inhibits the primary afferent stimulation-evoked excitation of dorsal horn neurons in normal rats and in rats with streptozotocin-induced painful diabetic neuropathy. Under normal conditions, stimulation of a dorsal root evoked Ca(2+) signals predominantly in the superficial dorsal horn. Clinically relevant (10μM) and a very high concentration of pregabalin (100μM) did not affect the intensity or spread of dorsal root stimulation-evoked Ca(2+) signals, whereas an extremely high dose of pregabalin (300μM) slightly but significantly attenuated Ca(2+) signals in normal rats and in diabetic neuropathic (DN) rats. There was no difference between normal rats and DN rats with regard to the extent of signal attenuation at all concentrations tested. These results suggest that the activity of dorsal horn neurons in the spinal cord is not inhibited acutely by clinical doses of pregabalin under normal or DN conditions. It is very unlikely that an acute inhibitory action in the dorsal horn is the main analgesic mechanism of pregabalin in neuropathic pain states. PMID:27543338

    Objective Endovascular repair (EVAR) of ruptured abdominal aortic aneurysm (rAAA) has become first-line therapy at our institution and is performed under a standardized protocol. We compare perioperative mortality, midterm survival, and morbidity after EVAR and open surgical repair (OSR). Methods Records were retrospectively reviewed from May 2000 to September 2010 for repair of infrarenal rAAAs. Primary end points included perioperative mortality and midterm survival. Secondary end points included acute limb ischemia, length of stay, ventilator-dependent respiratory failure, myocardial infarction, renal failure, abdominal compartment syndrome, and secondary intervention. Statistical analysis was performed using the t-test,X2 test, the Fisher exact test, and logistic regression calculations. Midterm survival was assessed with Kaplan-Meier analysis and Cox proportional hazard models. Results Seventy-four infrarenal rAAAs were repaired, 19 by EVAR and 55 by OSR. Despite increased age and comorbidity in the EVAR patients, perioperative mortality was 15.7% for EVAR, which was significantly lower than the 49% for OSR (odds ratio, 0.19; 95% CI, 0.05-0.74; P = .008). Midterm survival also favored EVAR (hazard ratio, 0.40; 95% CI, 0.21-0.77; P = .028, adjusted for age and sex). Mean follow-up was 20 months, and 1-year survival was 60% for EVAR vs 45% for OSR. Mean length of stay for patients surviving >1 day was 10 days for EVAR and 21 days for OSR (P = .004). Ventilator-dependent respiratory failure was 5% in the EVAR group vs 42% for OSR (odds ratio, 0.08; 95% CI, 0.01-0.62; P = .001). Conclusions EVAR of rAAA has a superior perioperative survival advantage and decreased morbidity vs OSR. Although not statistically significant, overall survival favors EVAR. We recommend that EVAR be considered as the first-line treatment of rAAAs and practiced as the standard of care. PMID:22626871

    The objective of the work was to study morphometric and cytological indexes of the spleen in mature and old laboratory animals after acute blood loss on the background of allogenic transplantation of placenta MMSC and GSC. The study proved that 5 days after acute blood loss on the background of stem cells transplantations to the mature animals there was a reduction of lymphoid follicles area due to reduction in thymus independent area. There were no immunosuppressive effects to the white pulp of the spleen in old animals. The increase of leucocytes' and erythrocytes' elements in red pulp in the mature animals was noted. In old animals, the increase of cells' density in red pulp is mainly due to increased number of erythroid cells. PMID:26856082

    2011-07-01

    Cardiopulmonary dysfunction and failure are commonly encountered in the patient with intra-abdominal hypertension (IAH) or abdominal compartment syndrome. Accurate assessment and optimization of preload, contractility, and afterload in conjunction with appropriate goal-directed resuscitation and assessment of fluid responsiveness are essential to restore end-organ perfusion. In patients with IAH, the traditional "barometric" preload indicators such as pulmonary artery occlusion pressure and central venous pressure are erroneously increased. Volumetric monitoring techniques have been proven to be superior in directing the appropriate resuscitation together with targeted abdominal perfusion pressure. If such limitations are not recognized, misinterpretation of the patient's cardiac status is likely, resulting in inappropriate and potentially detrimental therapy. IAH also markedly affects the mechanical properties of the chest wall and consequently also the respiratory function. Altered mechanical properties of the chest wall may limit ventilation, influence the work of breathing, affect the interaction between the respiratory muscles, hasten the development of respiratory failure, and interfere with gas exchange. Pulmonary monitoring is important to understand the relationships between intra-abdominal pressure and chest wall mechanics and the impact of IAH on ventilator-induced lung injury, lung distention, recruitment, and lung edema.

    One hundred and thirty hepatic resections performed over an 8-year period were reviewed for evidence of postoperative intra-abdominal sepsis. Of 126 patients who survived for more than 24 hours after operation, 36 developed culture positive intra-abdominal collections (28.6%). Significant independent variables associated with the development of intra-abdominal sepsis were diagnoses of trauma or cholangiocarcinoma, and the need for reoperation to control hemorrhage during the postoperative period. Before 1984, infected fluid collections were treated predominantly by operative drainage, but this has largely been replaced by percutaneous methods, which have proven effective in most cases. Eighteen (50%) of the infections were caused by a mixed bacterial culture, with Streptococcus faecalis, Staphylococcus epidermidis, Staphylococcus aureus and Escherichia coli being the most common isolates. Six patients with clinical signs of sepsis had a sterile fluid collection drained with complete relief of symptoms. This review suggests that intra-abdominal sepsis is a frequent complication after hepatic resection, and can often be managed successfully by nonoperative percutaneous drainage. PMID:2493775

    Diagnosis of abuse in children with internal abdominal injury is difficult because of limited published work. We aimed to ascertain the incidence of abdominal injury due to abuse in children age 0-14 years. 20 children (identified via the British Paediatric Surveillance Unit) had abdominal injuries due to abuse and 164 (identified via the Trauma Audit and Research Network) had injuries to the abdomen due to accident (112 by road-traffic accidents, 52 by falls). 16 abused children were younger than 5 years. Incidence of abdominal injury due to abuse was 2.33 cases per million children per year (95% CI 1.43-3.78) in children younger than 5 years. Six abused children died. 11 abused children had an injury to the gut (ten small bowel) compared with five (all age >5 years) who were injured by a fall (relative risk 5.72 [95% CI 2.27-14.4]; p=0.0002). We have shown that small-bowel injuries can arise accidentally as a result of falls and road-traffic accidents but they are significantly more common in abused children. Therefore, injuries to the small bowel in young children need special consideration, particularly if a minor fall is the explanation. PMID:16023514

    Imaging of pregnant patients with non-obstetric abdominal pain is reviewed, with an accompanying pictorial essay of cases with concentration on magnetic resonance imaging. Non-obstetric causes of abdominal pain during pregnancy are similar to those of non-pregnant patients. The most common causes are appendicitis and cholecystitis. Other causes are myriad and include biliary, gastrointestinal, infectious, inflammatory, and malignant etiologies, among others. The approach to imaging in pregnant patient is unique, as it is imperative to minimize potentially harmful radiation exposures to the fetus. Ultrasound and MRI are the primary modalities for evaluation of the pregnant patient with abdominal pain. The use of intravenous contrast is discouraged, except in highly-selected patients where there is no other way to obtain vital diagnostic information. CT is still used as the mainstay of evaluation of blunt abdominal trauma and is commonly used for diagnosis of small bowel obstruction, stone disease, and work-up of malignancy during pregnancy. A discussion of test selection and underlying rationale is presented. PMID:22160283

    An obese lady of 51 year with Type 2 Diabetes Mellitus for 13 years was prescribed Liraglutide, a glucagon like peptide (GLP-1) analogue (Victoza) for glycaemic control and reduction of weight. She was on gliclazide and Insulin prior to initiation of Liraglutide. Eight weeks after initiation of GLP -1 analogue, she developed severe abdominal pain, nausea and vomiting. She was admitted to a private hospital and evaluated. Biochemical tests and CT scan revealed presence of pancreatitis and she was treated for acute pancreatitis. Liraglutide was withdrawn and symptoms subsided. Subsequent follow-up showed that pancreatic enzyme levels were normal. PMID:25327099

    We describe a case of a 62-year-old woman with a history of chronic obstructive pulmonary disease and gastro-oesophageal reflux disease who presented to the emergency department with left lower quadrant abdominal pain, flank pain with nausea and no history of preceding trauma. The patient had finished a course of azithromycin and oral methylprednisolone 1 day prior to presentation. Abdominal and pelvic CT scan identified changes suggestive of bilateral adrenal haemorrhage. The patient did not show signs of acute adrenal insufficiency but was started on steroid replacement therapy because of concerns about possible disease progression. All recognised causes of adrenal haemorrhage were excluded suggesting this was a case of spontaneous idiopathic bilateral adrenal haemorrhage, a rarely reported phenomenon in the literature. The patient was discharged after clinical improvement following 6 days in hospital, taking oral steroid replacement. PMID:27166002

    Introduction Negative pressure wound therapy (NPWT) for abdominal surgical site infection (SSI) is becoming increasingly common, although enterocutaneous fistula (ECF) has been reported as a complication. To avoid ECF, we used computed tomography (CT) woundgraphy to evaluate the relationship between the wound and the intestine, and then safely treated the abdominal SSI with NPWT. Case presentation Following a laparoscopic intersphincteric resection for low rectal neuroendocrine tumor and covering ileostomy, a 59-year-old woman underwent stoma closure. Six days after surgery, we diagnosed SSI. We suspected ECF, because the wound was deep and the pus resembled enteric fluid. However, CT woundgraphy showed that the wound was separated from the abdominal cavity and the intestine by the abdominal rectus muscle. Accordingly, we performed NPWT. SSI was cured and the wound was well granulated. Twenty-three days after surgery, the patient was discharged. Eventually, the wound was completely epithelialized. Discussion Although successful NPWT has been reported for open abdominal wounds, ECF is a common complication. ECF can be prevented by separating the wound from the intestine by the omentum or muscle fascia, protecting the intestinal serosa during surgery, and applying low vacuum pressure. The relationships among the wound, the fascia, and the intestine must be evaluated before abdominal SSI treatment. One good method is CT woundgraphy, which evaluates wound extent and depth, closure of muscle fascia, and the relationship between the wound and the intestine. Conclusion We report a case of CT woundgraphy before NPWT for abdominal SSI. CT woundgraphy is a good candidate for evaluating wound condition. PMID:27002290

    Context/objective: Abdominal lipectomy is performed by plastic surgeons to provide symptomatic, functional, and cosmetic relief for patients with excess abdominal tissue. However, there are few clinical outcome studies looking at the utility of this procedure: this is the first prospective oucomes study. Design: Patients who underwent abdominal lipectomy at the Bellflower Medical Center during a 12-month period (September 2004 through September 2005) were prospectively studied. Data were collected at the preoperative visit, during surgery, and at the one-week, one-month, and six-month postoperative visits. Outcome measures: Complications, both major (requiring rehospitalization or reoperation) and minor (requiring local outpatient care) were identified. To evaluate the impact on our patients' perceived health and well-being as well as body image, we administered the Short Form–36 Health Survey (SF-36) and the Multidimensional Body-Self Relations Questionnaire (MBSRQ) to participants at their preoperative and six-month postoperative visits. Results: For the 72 patients enrolled in the study, the postoperative major complication rate was 5.6% (four patients) and the minor complication rate was 27.8% (20 patients); 98.3% were happy to have had the surgery. Two components of the MBSRQ, feelings of attractiveness and body area satisfaction, showed significant improvement (p < 0.0001 for each) at six-month postoperative testing. No component of the SF-36 reached statistical significance between pre- and postoperative testing. Conclusion: Because the complication rate for cosmetic abdominoplasty in our study did not significantly differ from rates reported for other studies, and given our data on perceived patient satisfaction and improvement in outcomes, our study validates the utility of abdominal lipectomy for patients with symptomatic lower abdominal pannus.

    Lateral abdominal wall muscles in children and adolescents have not been characterised to date. In the present report, we examined the reliability of the ultrasound measurement and thickness of the oblique external muscle (OE), oblique internal muscle (OI) and transverse abdominal muscle (TrA) at rest and during abdominal drawing-in manoeuvre (ADIM) on both sides of the body in healthy adolescents. We also determined possible differences between boys and girls and defined any factors-such as body mass, height and BMI-that may affect the thickness of the abdominal muscles. B-mode ultrasound was used to assess OE, OI and TrA on both sides of the body in the supine position. Ultrasound measurements at rest and during ADIM were reliable in this age group (ICC3,3 > 0.92). OI was always the thickest and TrA the thinnest muscle on both sides of the body. In this group, an identical pattern of the contribution of the individual muscles to the structure of the lateral abdominal wall (OI > OE > TrA) was observed. At rest and during ADIM, no statistically significant side-to-side differences were demonstrated in either gender. The body mass constitutes between 30% and <50% of the thickness differences in all muscles under examination at rest and during ADIM. The structure of lateral abdominal wall in adolescents is similar to that of adults. During ADIM, the abdominal muscles in adolescents react similarly to those in adults. This study provided extensive information regarding the structure of the lateral abdominal wall in healthy adolescents. PMID:25088309

    Mycotic aneurysms of the abdominal aorta are uncommon, but potentially lethal problems. Clinical subtleties may suggest their presence, but in the past, definitive diagnosis has been dependent on surgical exploration or autopsy findings. A case is presented in which 67-gallium citrate abdominal scanning localized the site of sepsis in an abdominal aortic aneurysm and allowed for prompt and successful surgical therapy. This noninvasive technique is recommended as a adjunct in the diagnosis of mycotic abdominal aortic aneurysms.

    Acute intermittent porphyria (AIP), the most common and the most severe form of acute hepatic porphyria, is an autosomal dominant condition. It results from lower-than-normal levels (less than 50%) of porphobilinogen (PBG) deaminase. Patients may present commonly with gastrointestinal complaints and neuropsychiatric manifestations. Diagnosis may be confirmed with the presence of intermediary metabolites of haem synthesis, amino levulinic acid (ALA) and PBG in urine or with specific enzyme assays. Abdominal pain is the most common symptom (90%). Peripheral polyneuropathy, primarily motor with flaccid paresis of proximal musculature, with or without autonomic involvement, is characteristic. Respiratory failure necessitates ventilator and intensive care support. Avoidance of precipitating factors and the use of haem preparations and intravenous dextrose form the basis of management. Gabapentin and propofol, rather than the conventional antiepileptics appear to be the appropriate choice for seizure control. Here, we present intensive care management of four cases of AIP with varying clinical presentation. PMID:20859493

    Intra-abdominal pressure (IAP) and abdominal perfusion pressure (APP) have shown clinical relevance in monitoring critically ill human beings submitted to abdominal surgery. Only a few studies have been performed in veterinary medicine. The aim of this study was to assess how pregnancy and abdominal surgery may affect IAP and APP in healthy cats. For this purpose, pregnant (n=10) and non-pregnant (n=11) queens undergoing elective spaying, and tomcats (n=20, used as controls) presented for neutering by scrotal orchidectomy were included in the study. IAP, mean arterial blood pressure (MAP), APP, heart rate and rectal temperature (RT) were determined before, immediately after, and four hours after surgery. IAP increased significantly immediately after abdominal surgery in both female groups when compared with baseline (P<0.05) and male (P<0.05) values, and returned to initial perioperative readings four hours after surgery. Tomcats and pregnant females (P<0.05) showed an increase in MAP and APP immediately after surgery decreasing back to initial perioperative values four hours later. A significant decrease in RT was appreciated immediately after laparotomy in both pregnant and non-pregnant queens. IAP was affected by abdominal surgery in this study, due likely to factors, such as postoperative pain and hypothermia. Pregnancy did not seem to affect IAP in this population of cats, possibly due to subjects being in early stages of pregnancy. PMID:23118052

    2012-01-01

    Intra-abdominal hypertension (IAH) and abdominal compartment syndrome (ACS) are common complications of ruptured abdominal aortoiliac aneurysms (rAAAs) and other abdominal vascular catastrophes even in the age of endovascular therapy. Morbidity and mortality due to systemic inflammatory response syndrome (SIRS) and multiple organ failure (MOF) are significant. Recognition and management of IAH are key critical care measures which may decrease morbidity and improve survival in these vascular patients. Two strategies have been utilized: expectant management with prompt decompressive laparotomy upon diagnosis of threshold levels of IAH versus prophylactic, delayed abdominal closure based upon clinical parameters at the time of initial repair. Competent management of the abdominal wound with preservation of abdominal domain is also an important component of the care of these patients. In this review, we describe published experience with IAH and ACS complicating abdominal vascular catastrophes, experience with ACS complicating endovascular repair of rAAAs, and techniques for management of the abdominal wound. Vigilance and appropriate management of IAH and ACS remains critically important in decreasing morbidity and optimizing survival following catastrophic intra-abdominal vascular events. PMID:22454763

    Pazopanib is an oral angiogenesis inhibitor targeting vascular endothelial growth factor receptors, platelet-derived growth factor receptors, and c-Kit approved for the treatment of renal cell carcinoma and soft tissue sarcoma. Nonselective kinase inhibitors, such as sunitinib and sorafenib, are known to be associated with acute pancreatitis. There are few case reports of severe acute pancreatitis induced by pazopanib treatment. We present a case of severe acute pancreatitis caused by pazopanib treatment for cutaneous angiosarcoma. The patient was an 82-year-old female diagnosed with cutaneous angiosarcoma. She had been refractory to docetaxel treatment and began pazopanib therapy. Three months after pazopanib treatment, CT imaging of the abdomen showed the swelling of the pancreas and surrounding soft tissue inflammation without abdominal pain. After she continued pazopanib treatment for 2 months, she presented with nausea and appetite loss. Abdominal CT showed the worsening of the surrounding soft tissue inflammation of the pancreas. Serum amylase and lipase levels were 296 and 177 IU/l, respectively. She was diagnosed with acute pancreatitis induced by pazopanib treatment and was managed conservatively with discontinuation of pazopanib, but the symptoms did not improve. Subsequently, an abdominal CT scan demonstrated the appearance of a pancreatic pseudocyst. She underwent endoscopic ultrasound-guided pseudocyst drainage using a flared-end fully covered self-expandable metallic stent. Then, the symptoms resolved without recurrence. Due to the remarkable progress of molecular targeted therapy, the oncologist should know that acute pancreatitis was recognized as a potential adverse event of pazopanib treatment and could proceed to severe acute pancreatitis.

    Abstract Renal enlargement at time of diagnosis of acute leukemia is very unusual. We here in report 2 pediatric cases of acute leukemia who had their renal affection as the first presenting symptom with no evidences of blast cells in blood smear and none of classical presentation of acute leukemia. The first case is a 4-year-old girl who presented with pallor and abdominal enlargement. Magnetic resonance imaging showed bilateral symmetrical homogenous enlarged kidneys suggestive of infiltration. Complete blood picture (CBC) revealed white blood count 11 × 109/L, hemoglobin 8.7 g/dL and platelet count 197 × 109/L. Bone marrow aspiration was performed, and diagnosed precursor B-cell ALL was made. The child had an excellent response to modified CCG 1991 standard risk protocol of chemotherapy with sustained remission, but unfortunately relapsed 11 month after the end of therapy. The second child was 13-month old, presented with pallor, vomiting, abdominal enlargement, and oliguria 2 days before admission. Initial CBC showed bicytopenia, elevated blood urea, creatinine, and serum uric acid, while abdominal ultrasonography revealed bilateral renal enlargement. Bone marrow examination was done and showed 92% blast of biphenotypic nature. So, biphynotypic leukemia with bilateral renal enlargement and acute renal failure was subsequently diagnosed. The patients admitted to ICU and received supportive care and prednisolone. Renal function normalized and chemotherapy was started. The child achieved complete remission with marked reduction of kidney size but, unfortunately she died from sepsis in consolidation phase of therapy. This case demonstrates an unusual early renal enlargement in childhood acute leukemia. Renal involvement of acute leukemia should be considered in child presenting with unexplained bilateral renal enlargement with or without renal function abnormalities and bone marrow examination should be included in the workup.

    INTRODUCTION Transmesenteric mesocolic hernias are a rare cause of acute abdomen in adults with few reported cases in published literature. PRESENTATION OF CASE We report a rare case of a 30-year-old male with right-sided transmesenteric hernia of ileum due to a congenital mesocolic defect resulting in acute abdomen, presenting as acute abdomen. The hernia was reduced, small bowel inspected for gangrene and mesenteric hernia repaired, following which the patient made a good recovery and was discharged 5 days later. DISCUSSION The insidious onset of transmesenteric herniae and lack of specific radiological or laboratory investigations reaffirms the importance of surgeons maintaining a high index of suspicion for this surgical emergency. CONCLUSION Transmesentric hernia though rare can present as a case of acute abdomen in an emergency. The diagnosis is purely by a CT scan and close monitoring of the patient's general condition in cases of non-specific abdominal pain is essential to identify the rare deteriorating patient for early surgical intervention and optimal outcome.

    Acute pancreatitis is rare in pregnancy, with an estimated incidence of approximately 1 in 1000 to 1 in 10,000 pregnancies. Acute pancreatitis in pregnancy usually occurs in the third trimester. Here, we report a case of acute pancreatitis in the first trimester. A 36-year-old primigravida at 11 weeks of gestation complained of severe lower abdominal pain. The pain gradually worsened and migrated toward the epigastric region. She had no history of chronic alcoholism. Blood investigations showed elevated level of C-reactive protein (9.58 mg/dL), pancreatic amylase (170 IU/L), and lipase (332 IU/L). There was no gallstone and no abnormality in the pancreatic and biliary ducts on ultrasonography. Antinuclear antibody and IgG4 were negative and no evidence of hyperlipidemia or diabetes was found. There was also no evidence of viral infection. On the third day of hospitalization, she was diagnosed with severe acute pancreatitis on magnetic resonance imaging. Medical interventions were initiated with nafamostat mesilate and ulinastatin, and parenteral nutrition was administered through a central venous catheter. On the eighth day of hospitalization, her condition gradually improved with a decreased level of pancreatic amylase and the pain subsided. After conservative management, she did not have any recurrence during her pregnancy. PMID:26843995

    Introduction Intestinal obstruction following abdominal trauma has previously been described. However, in most reported cases pathological finding was intestinal stenosis. Presentation of the case A 51-year-old male was admitted after a motor vehicle accident. Initial focused abdominal sonogram for trauma and enhanced computerized tomography were normal, however there was a fracture of the tibia. Three days later, he complained of abdominal pain, constipation, and vomiting. An exploratory laparotomy showed bleeding from the omentum and mechanical small bowel obstruction due to a fibrous band. Discussion The patient had prior abdominal surgery, but clinical and radiological findings indicate that the impact of the motor vehicle accident initiated his condition either by causing rotation of a bowel segment around the fibrous band, or by formation of a fibrous band secondary to minimal bleeding from the omentum. Conclusion High index of suspicion of intestinal obstruction is mandatory in trauma patients presenting with complaints of abdominal pain, vomiting, and constipation despite uneventful CT scan.

    Acute abdomen is a medical emergency, in which there is sudden and severe pain in abdomen of recent onset with accompanying signs and symptoms that focus on an abdominal involvement. It can represent a wide spectrum of conditions, ranging from a benign and self-limiting disease to a surgical emergency. Nevertheless, only one quarter of patients who have previously been classified with an acute abdomen actually receive surgical treatment, so the clinical dilemma is if the patients need surgical treatment or not and, furthermore, in which cases the surgical option needs to be urgently adopted. Due to this reason a thorough and logical approach to the diagnosis of abdominal pain is necessary. Some Authors assert that the location of pain is a useful starting point and will guide a further evaluation. However some causes are more frequent in the paediatric population (like appendicitis or adenomesenteritis) or are strictly related to the gender (i.e. gynaechologic causes). It is also important to consider special populations such as the elderly or oncologic patients, who may present with atypical symptoms of a disease. These considerations also reflect a different diagnostic approach. Today, surely the integrated imaging, and in particular the use of multidetector Computed Tomography (MDCT) has revolutionised the clinical approach to this condition, simplyfing the diagnosis but burdening the radiologists with the problems related to the clinical management. However although CT emerging as a modality of choice for evaluation of the acute abdomen, ultrasonography (US) remains the primary imaging technique in the majority of cases, especially in young and female patients, when the limitation of the radiation exposure should be mandatory, limiting the use of CT in cases of nondiagnostic US and in all cases where there is a discrepancy between the clinical symptoms and negative imaging at US.

    Sclerosing encapsulating peritonitis (SEP) or abdominal cocoon is a rare acquired condition with an unknown aetiology. It is characterized by encapsulation of the small bowel by a fibrous membrane and can lead to intestinal obstruction. We present the case of a 42-year-old gentleman with a history of hepatitis C, tuberculosis, and previous abdominal surgery, who presented with subacute intestinal obstruction. Surgical exploration of the abdomen revealed that the entire contents were enclosed into three distinct sacs by a dense fibrous membrane. Excision of the sacs was performed followed by adhesiolysis. This is believed to be the first reported case of multiple cocoons within the abdominal cavity. The case is discussed with reference to the literature. PMID:25893128
