    The association of maternal uniparental disomy of human chromosome 7 (upd(7) mat) and the growth retardation disorder Silver-Russell syndrome (SRS) is well established, but the causative gene or region is currently unknown. However, several observations indicate that molecular alterations of the genomically imprinted MEST region in 7q32.2 are associated with growth retardation and a phenotype reminiscent to SRS. We now report on a second patient with a similar phenotype and a de novo 7q32.2 microdeletion including MEST affecting the paternal allele. This confirms the central role of imprinted genes in 7q32.2 in the etiology of a growth retardation phenotype associated with SRS features. PMID:26663145

    An important gene involved in the pathogenesis of obesity is the product of the human homologue of the murine obese gene (gene symbol OBS). Using fluorescence in situ hybridization (FISH), we have localized the human OB gene to human chromosome 7, specifically to region 7q32.1. The FISH data of human OBS provide a gene-associated marker for genetic mapping. 8 refs., 1 fig.

    We have developed a strategy for the isolation of terminal deletion breakpoints from any chromosome that has been healed by de novo addition of a telomere repeat array. Breakpoints at 7q32 and 22q13.3 have been isolated and characterized in two patients (patients FB336R and AJ). Both truncated chromosomes have been healed by the addition of a novel telomere, with such an addition possibly mediated by the enzyme telomerase. The breakpoint at 7q32 in patient FB336R shows a structure similar to that of breakpoints on other chromosomes that have been healed in this way. However, the breakpoint at 22q13.3 in patient AJ has 10 nucleotides of unknown origin inserted between the sequence unique to chromosome 22q and the start of the telomere repeat array. This unusual structure is suggestive of a multistep healing event resulting in de novo telomere addition at this breakpoint, and possible mechanisms are discussed. PMID:10924407

  4. Smith-Lemli-Opitz syndrome in a female with a de novo, balanced translocation involving 7q32: Probable disruption of an SLOS gene

    A 3-month-old infant girl had manifestations of the Smith-Lemli-Opitz syndrome (SLOS) including typical positional anomalies of the limbs, apparent Hirschsprung disease, cataracts, ptosis, anteverted nares, cleft of the posterior palate, small tongue, broad maxillary alveolar ridges, and abnormally low serum cholesterol levels. Chromosomal analysis showed a de novo balanced translocation interpreted as 46,XX,t(7;20)(q32.1;q13.2). We hypothesize that the translocation breakpoint in this case interrupts one SLOS allele and that the other allele at the same locus has a more subtle mutation that was inherited from the other parent. This case, as well as cytogenetic observations in other SLOS cases, suggests that SLOS could be due to autosomal recessive mutation at a gene in 7q32. 33 refs., 3 figs., 1 tab.

    To further characterize the genetic basis of primary biliary cirrhosis (PBC), we genotyped 2426 PBC patients and 5731 unaffected controls from three independent cohorts using a single nucleotide polymorphism (SNP) array (Immunochip) enriched for autoimmune disease risk loci. Meta-analysis of the genotype data sets identified a novel disease-associated locus near the TNFSF11 gene at 13q14, provided evidence for association at six additional immune-related loci not previously implicated in PBC and confirmed associations at 19 of 22 established risk loci. Results of conditional analyses also provided evidence for multiple independent association signals at four risk loci, with haplotype analyses suggesting independent SNP effects at the 2q32 and 16p13 loci, but complex haplotype driven effects at the 3q25 and 6p21 loci. By imputing classical HLA alleles from this data set, four class II alleles independently contributing to the association signal from this region were identified. Imputation of genotypes at the non-HLA loci also provided additional associations, but none with stronger effects than the genotyped variants. An epistatic interaction between the IL12RB2 risk locus at 1p31and the IRF5 risk locus at 7q32 was also identified and suggests a complementary effect of these loci in predisposing to disease. These data expand the repertoire of genes with potential roles in PBC pathogenesis that need to be explored by follow-up biological studies. PMID:22936693

    Chromosomal deletions associated with human diseases, such as cancer are common, but synteny issues complicate modeling of these deletions in mice. We use cellular reprogramming and genome engineering to functionally dissect the loss of chromosome 7q [del(7q)], a somatic cytogenetic abnormality present in myelodysplastic syndromes (MDS). We derive del(7q)- and isogenic karyotypically normal induced pluripotent stem cells (iPSCs) from hematopoietic cells of MDS patients and show that the del(7q) iPSCs recapitulate disease-associated phenotypes, including impaired hematopoietic differentiation. These disease phenotypes are rescued by spontaneous dosage correction and can be reproduced in karyotypically normal cells by engineering hemizygosity of defined chr7q segments, in a 20 Mb region. We use a phenotype-rescue screen to identify candidate haploinsufficient genes that might mediate the del(7q)- hematopoietic defect. Our approach highlights the utility of human iPSCs both for functional mapping of disease-associated large-scale chromosomal deletions and for discovery of haploinsufficient genes. PMID:25798938

    Nuclear respiratory factors 1 and 2 (NRF-1 and NRF-2) were first recognized as transcriptional activators of several genes involved in oxidative phosphorylation (OYPHOS). Cis-acting functional NRF-1 and NRF-2 sites are present in the gene encoding cytochrome c and in nuclear genes encoding different subunits of respiratory complexes III, IV, and V. NRF-1 and NRF-2 binding sites have also been found in genes encoding the RNA subunit of MRP endonuclease and the gene for mitochondrial transcription factor A (TCF6). MRP endonuclease is a ribonucleoprotein enzyme possibly involved in cleavage of the light-strand transcripts serving as primers for heavy-strand replication; the product of TCF6 stimulates transcription initiation, and, by controlling light-strand transcription, it is thought to modulate mtDNA replication as well. Furthermore, NRF-1 is required for expression of the gene encoding 5-aminolevulinate synthase, the rate-limiting enzyme in the biosynthesis of heme for respiratory cytochromes. Therefore, NRF-1 plays a major integrative role in controlling numerous nuclear-mitochondrial interactions in higher organisms. 12 refs., 1 fig.

    Smith-Lemli-Opitz syndrome (SLOS) is a mental retardation/multiple congenital anomaly syndrome. The gene(s) involved has not been mapped or cloned, but, recently, a biochemical abnormality in cholesterol biosynthesis has been shown to occur in most SLOS patients. The defect is suspected to occur in the penultimate step of the cholesterol pathway, involving the enzyme 7-dehydrocholesterol reductase, which has not been isolated. On the basis of the hypothesis that a de novo balanced translocation [t(7;20)(q32.1;q13.2)] in an SLOS patient directly interrupts the SLOS gene, positional cloning techniques are being employed to localize and identify the SLOS gene. We report the identification of a chromosome 7-specific YAC that spans the translocation breakpoint, as detected by FISH. This is the first study narrowing a candidate SLOS region and placing it on physical and genetic maps of the human genome. Images Figure 1 PMID:7762564

    The purpose of this study was to review the data on the etiology, risk factors, clinical presentations, and diagnosis of acute sacroiliitis. A Pubmed search utilizing the indexing term "acute sacroiliitis" was conducted and the data pertinent to the aim of the review was extracted and organized in accordance with the preplanned structure of the manuscript. The diagnosis of acute sacroiliitis is often challenging because of both the relative rarity of this presentation and diverse character of acute sacroiliac pain, frequently mimicking other, more prevalent disorders. Technetium bone scintigraphy can localize the disease process to the sacroiliac joint, while computed tomography or magnetic resonance imaging can be used for the detailed characterization and the extent of the disease as well as the diagnosis of complications. Pyogenic sacroiliitis is by far the most common cause of acute sacroiliitis. Brucellosis, acute sacroiliitis in the course of reactive arthritis, and crystalline-induced sacroiliitis frequently imitate pyogenic sacroiliitis. Acute sacroiliitis can rarely be also related to hematological malignancies or treatment with isotretinoin. Awareness to the possibility of acute sacroiliitis and a thorough physical examination are the necessary prerequisites to its timely diagnosis, while the appropriate laboratory and imaging studies should confirm the precise diagnosis and direct the appropriate treatment strategy.

    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

    Acute pneumonia is an active infection of the lungs that results when an individual at risk gets exposed to a particular microbiological pathogen. Acute pneumonia is the leading cause of death in the United States that is attributable to an infection. The risk factors, pathogenesis, and microbiological organisms involved differ if the pneumonia develops in the community versus health care-associated environment. The development of concise and comprehensive guidelines has led to an improvement in the management of the problem. However, the emergence of multidrug-resistant organisms and the increase in the percentage of elderly population keep mortality risk very substantial. PMID:26919676

    For many decades two types of acute pancreatitis have been recognized: the edematous or interstitial and the hemorrhagic or necrotic. In most cases acute pancreatitis is associated with alcoholism or biliary tract disease. Elevated serum or urinary α-amylase is the most important finding in diagnosis. The presence of methemalbumin in serum and in peritoneal or pleural fluid supports the diagnosis of the hemorrhagic form of the disease in patients with a history and enzyme studies suggestive of pancreatitis. There is no characteristic clinical picture in acute pancreatitis, and its complications are legion. Pancreatic pseudocyst is probably the most common and pancreatic abscess is the most serious complication. The pathogenetic principle is autodigestion, but the precise sequence of biochemical events is unclear, especially the mode of trypsinogen activation and the role of lysosomal hydrolases. A host of metabolic derangements have been identified in acute pancreatitis, involving lipid, glucose, calcium and magnesium metabolism and changes of the blood clotting mechanism, to name but a few. Medical treatment includes intestinal decompression, analgesics, correction of hypovolemia and other supportive and protective measures. Surgical exploration is advisable in selected cases, when the diagnosis is in doubt, and is considered imperative in the presence of certain complications, especially pancreatic abscess.

    Acute diarrhea in adults is a common problem encountered by family physicians. The most common etiology is viral gastroenteritis, a self-limited disease. Increases in travel, comorbidities, and foodborne illness lead to more bacteria-related cases of acute diarrhea. A history and physical examination evaluating for risk factors and signs of inflammatory diarrhea and/or severe dehydration can direct any needed testing and treatment. Most patients do not require laboratory workup, and routine stool cultures are not recommended. Treatment focuses on preventing and treating dehydration. Diagnostic investigation should be reserved for patients with severe dehydration or illness, persistent fever, bloody stool, or immunosuppression, and for cases of suspected nosocomial infection or outbreak. Oral rehydration therapy with early refeeding is the preferred treatment for dehydration. Antimotility agents should be avoided in patients with bloody diarrhea, but loperamide/simethicone may improve symptoms in patients with watery diarrhea. Probiotic use may shorten the duration of illness. When used appropriately, antibiotics are effective in the treatment of shigellosis, campylobacteriosis, Clostridium difficile, traveler's diarrhea, and protozoal infections. Prevention of acute diarrhea is promoted through adequate hand washing, safe food preparation, access to clean water, and vaccinations. PMID:24506120

    2000-09-01

    Acute glomerulonephritis (AGN) is a representative disease of acute nephritic syndrome characterized by the sudden appearance of edema, hematuria, proteinuria, and hypertension. The prototype of AGN is acute poststreptococcal glomerulonephritis (APSGN). "Nephritogenic streptococci" are defined as organisms that are cultured from a patient who develops AGN. Although only a limited number of M-types of streptococci have been recognized as "nephritogenic streptococci", all M-types of streptococci may have nephritogenic potential because the genes for major putative nephritogenic antigens such as SPEB and NAPIr are found to be present in all group A streptococci thus far examined. Pathogenic mechanisms for APSGN involving both humoral and cell-mediated immunity have been recently proposed. The role of humoral immunity is presumed to be mediated by the in situ formation of nephritogenic streptococcal antigen-antibody complexes and circulating immune complexes. While in the cellular immune component a role for delayed-type hypersensitivity has been suggested to contribute to the pathogenesis of APSGN. PMID:10969898

    Myocarditis is defined as inflammation of the myocardium accompanied by myocellular necrosis. Acute myocarditis must be considered in patients who present with recent-onset of cardiac failure or arrhythmia. Fulminant myocarditis is a distinct entity characterized by sudden onset of severe congestive heart failure or cardiogenic shock, usually following a flu-like illness, parvovirus B19, human herpesvirus 6, coxsackievirus and adenovirus being the most frequently viruses responsible for the disease. Treatment of myocarditis remains largely supportive, since immunosuppression has not been proven to be beneficial for acute lymphocytic myocarditis. Trials of antiviral therapies, or immunostimulants such as interferons, suggest a potential therapeutic role but require further investigation. Lastly, early recognition of patients rapidly progressing to refractory cardiac failure and their immediate transfer to a medical-surgical center experienced in mechanical circulatory support is warranted. In this setting, ECMO should be the first-line mechanical assistance. For highly unstable patients, a Mobile Cardiac Assistance Unit, that rapidly travels to primary care hospitals with a portable ECMO system and hooks it up before refractory multiorgan failure takes hold, is the preferred option.

    1999-01-01

    The review of acute pain describes the problem of unresolved pain and its effects on the neural, autonomic, and immune systems. Conceptualizations and mechanisms of pain are reviewed as well as theories of pain management. Descriptive studies of patient and nurse factors that inhibit effective pain management are discussed, followed by studies of pharmacological and nonpharmacological interventions. Critical analysis reveals that most studies were atheoretical, and therefore, this proliferation of information lacked conceptual coherence and organization. Furthermore, the nature and extent of barriers to pain management were described, but few intervention studies have been devised, as yet, to modify the knowledge, beliefs, and attitudes of nurses and patients that are barriers to pain management. Although some of the complementary therapies have sufficient research support to be used in clinical pain management, the physiological mechanisms and outcomes need to be studied. It is critical at this time to design studies of interventions to improve assessment, decision making, attentive care, and patient teaching. PMID:10418655

    Intragenic ERG deletions occur in 3–5% of B-cell precursor acute lymphoblastic leukemia, specifically in B-other subtype lacking the classifying genetic lesions. They represent the only genetic lesion described so far present in the majority of cases clustering into a subgroup of B-other subtype characterized by a unique gene expression profile, probably sharing a common, however, not yet fully described, biological background. We aimed to elucidate whether ERG deletions could drive the specific biology of this ERG-related leukemia subgroup through expression of aberrant or decreased expression of wild type ERG isoforms. We showed that leukemic cells with endogenous ERG deletion express an aberrant transcript translated into two proteins in transfected cell lines and that one of these proteins colocalizes with wild type ERG. However, we did not confirm expression of the proteins in acute lymphoblastic leukemia cases with endogenous ERG deletion. ERG deletions resulted in significantly lower expression of wild type ERG transcripts compared to B-other cases without ERG deletion. However, cases with subclonal ERG deletion, clustering to the same ERG deletion associated subgroup, presented similar levels of wild type ERG as cases without ERG deletion. In conclusion, our data suggest that neither the expression of aberrant proteins from internally deleted allele nor the reduced expression of wild type ERG seem to provide a plausible explanation of the specific biology of ERG -related leukemia subgroup.

    Acute pancreatitis is an acute inflammation of the pancreas. Several classification systems have been used in the past but were considered unsatisfactory. A revised Atlanta classification of acute pancreatitis was published that assessed the clinical course and severity of disease; divided acute pancreatitis into interstitial edematous pancreatitis and necrotizing pancreatitis; discerned an early phase (first week) from a late phase (after the first week); and focused on systemic inflammatory response syndrome and organ failure. This article focuses on the revised classification of acute pancreatitis, with emphasis on imaging features, particularly on newly-termed fluid collections and implications for the radiologist.

    Acute loss of consciousness poses a fascinating scenario for theoretical and clinical research. This chapter introduces a simple yet powerful framework to investigate altered states of consciousness. We then explore the different disorders of consciousness that result from acute brain injury, and techniques used in the acute phase to predict clinical outcome in different patient populations in light of models of acute loss of consciousness. We further delve into post-traumatic amnesia as a model for predicting cognitive sequels following acute loss of consciousness. We approach the study of acute loss of consciousness from a theoretical and clinical perspective to conclude that clinicians in acute care centers must incorporate new measurements and techniques besides the classic coma scales in order to assess their patients with loss of consciousness.

    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

    The response of the primary care physician in the initial assessment and management of acute arterial injuries will often be the deciding factor in survival of life, limb or organ system. Most arterial emergencies occur as a result of trauma, disruption of vessel wall and/or occlusion of flow. The common clinical syndromes of acute arterial emergencies are injuries to and beyond the aorta, acute aortic dissection, ruptured aortic aneurysm, and thromboembolic occlusive arterial disease. The role of arteriography and the urgency of definitive surgical repair in acute arterial emergencies is summarized. PMID:21283323

    A review of the systemic acute phase reaction with major cytokines involved, and the hepatic metabolic changes, negative and positive acute phase proteins (APPs) with function and associated pathology is given. It appears that APPs represent appropriate analytes for assessment of animal health. Whereas they represent non-specific markers as biological effect reactants, they can be used for assessing nutritional deficits and reactive processes, especially when positive and negative acute phase variables are combined in an index. When such acute phase index is applied to separate healthy animals from animals with some disease, much better results are obtained than with single analytes and statistically acceptable results for culling individual animals may be reached. Unfortunately at present no cheap, comprehensive and easy to use system is available for assessing various acute phase proteins in serum or blood samples at the same time. Protein microarray or fluid phase microchip technology may satisfy this need; and permit simultaneous analysis of numerous analytes in the same small volume sample and enable integration of information derived from systemic reactivity and nutrition with disease specific variables. Applying such technology may help to solve health problems in various countries not only in animal husbandry but also in human populations. PMID:16252337

    2015-01-01

    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

    Acute genital ulcers, also known as acute vulvar ulcers, ulcus vulvae acutum or Lipschütz ulcers, refer to an ulceration of the vulva or lower vagina of non-venereal origin that usually presents in young women, predominantly virgins. Although its incidence is unknown, it seems a rare entity, with few cases reported in the literature. Their aetiology and pathogenesis are still unknown. The disease is characterised by an acute onset of flu-like symptoms with single or multiple painful ulcers on the vulva. Diagnosis is mainly clinical, after exclusion of other causes of vulvar ulcers. The treatment is mainly symptomatic, with spontaneous resolution in 2 weeks and without recurrences in most cases. We present a case report of a 13-year-old girl with two episodes of acute ulcers that fit the clinical criteria for Lipschütz ulcers. PMID:24473429

    Acute intermittent porphyria (AIP) is an autosomal dominant genetic defect in heme synthesis. Patients with this illness can have episodic life-threatening attacks characterized by abdominal pain, neurological deficits, and psychiatric symptoms. Feigning this illness has not been reported in the English language literature to date. Here, we report on a patient who presented to the hospital with an acute attack of porphyria requesting opiates. Diligent assessment of extensive prior treatment records revealed thirteen negative tests for AIP. PMID:25525547

    2016-10-01

    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

    Acute asthma is the third commonest cause of pediatric emergency visits at PGIMER. Typically, it presents with acute onset respiratory distress and wheeze in a patient with past or family history of similar episodes. The severity of the acute episode of asthma is judged clinically and categorized as mild, moderate and severe. The initial therapy consists of oxygen, inhaled beta-2 agonists (salbutamol or terbutaline), inhaled budesonide (three doses over 1 h, at 20 min interval) in all and ipratropium bromide and systemic steroids (hydrocortisone or methylprednisolone) in acute severe asthma. Other causes of acute onset wheeze and breathing difficulty such as pneumonia, foreign body, cardiac failure etc. should be ruled out with help of chest radiography and appropriate laboratory investigations in first time wheezers and those not responding to 1 h of inhaled therapy. In case of inadequate response or worsening, intravenous infusion of magnesium sulphate, terbutaline or aminophylline may be used. Magnesium sulphate is the safest and most effective alternative among these. Severe cases may need ICU care and rarely, ventilatory support. PMID:21769523

    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. Urgent management, including bone marrow biopsy for definitive diagnosis and urgent surgical intervention

    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.

    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.

With the help of computed tomography, the diagnosis was later revised to acute prevertebral calcific tendinitis, a self-limiting condition caused by abnormal calcium hydroxyapatite deposition in the longus colli muscles. It is critical to differentiate between these two disease entities due to dramatic differences in management.

    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

    Sixty-eight patients with acute acalculous cholecystitis were reviewed. The results of history and physical examinations were usually nondiagnostic. IDA cholescintigraphy (93 per cent accuracy rate) was the only reliable diagnostic modality. The results of oral cholecystography, intravenous cholangiography and ultrasonography were considerably less reliable. One-half of the patients had gangrenous cholecystitis. Cholecystectomy was the preferred operation with an over-all mortality of 9 per cent. IDA cholescintigraphy is an important new modality for the diagnosis of acute acalculous cholecystitis which, in the past, has often been difficult to diagnose.

    Premenopausal women with acute pelvic pain comprise a significant percentage of patients who present to the emergency room. Etiologies can be gynecologic, urologic, gastrointestinal, or vascular. Signs and symptoms are often nonspecific and overlapping. The choice of imaging modality is determined by the clinically suspected differential diagnosis. Ultrasound (US) is the preferred imaging modality for suspected obstetric or gynecologic disorders. CT is more useful when gastrointestinal or urinary tract pathology is likely. MR imaging is rarely used in the emergent setting, except to exclude appendicitis in pregnant women. This article presents a comprehensive review of imaging of acute gynecologic disorders.

    Accurate diagnosis of acute oral ulcers can be challenging. Important historic details include the pattern of recurrence, anatomic areas of involvement within the mouth and elsewhere on the mucocutaneous surface, associated medical symptoms or comorbidities, and symptomology. Careful mucocutaneous examination is essential. When necessary, biopsy at an active site without ulceration is generally optimal. Depending on the clinical scenario, supplemental studies that may be useful include cultures; perilesional biopsy for direct immunofluorescence testing; and evaluation for infectious diseases, gluten sensitivity, inflammatory bowel disease, human immunodeficiency virus infection, connective tissue diseases, or hematinic deficiencies. Clinicians should maintain a broad differential diagnosis when evaluating patients with acute oral ulcers. PMID:27343961

    2002-01-01

    Acute septic arthritis may develop as a result of hematogenous seeding, direct introduction, or extension from a contiguous focus of infection. The pathogenesis of acute septic arthritis is multifactorial and depends on the interaction of the host immune response and the adherence factors, toxins, and immunoavoidance strategies of the invading pathogen. Neisseria gonorrhoeae and Staphylococcus aureus are used in discussing the host-pathogen interaction in the pathogenesis of acute septic arthritis. While diagnosis rests on isolation of the bacterial species from synovial fluid samples, patient history, clinical presentation, laboratory findings, and imaging studies are also important. Acute nongonococcal septic arthritis is a medical emergency that can lead to significant morbidity and mortality. Therefore, prompt recognition, rapid and aggressive antimicrobial therapy, and surgical treatment are critical to ensuring a good prognosis. Even with prompt diagnosis and treatment, high mortality and morbidity rates still occur. In contrast, gonococcal arthritis is often successfully treated with antimicrobial therapy alone and demonstrates a very low rate of complications and an excellent prognosis for full return of normal joint function. In the case of prosthetic joint infections, the hardware must be eventually removed by a two-stage revision in order to cure the infection. PMID:12364368

  12. Acute radiation risk models

    NASA Astrophysics Data System (ADS)

    Smirnova, Olga

    Biologically motivated mathematical models, which describe the dynamics of the major hematopoietic lineages (the thrombocytopoietic, lymphocytopoietic, granulocytopoietic, and erythropoietic systems) in acutely/chronically irradiated humans are developed. These models are implemented as systems of nonlinear differential equations, which variables and constant parameters have clear biological meaning. It is shown that the developed models are capable of reproducing clinical data on the dynamics of these systems in humans exposed to acute radiation in the result of incidents and accidents, as well as in humans exposed to low-level chronic radiation. Moreover, the averaged value of the "lethal" dose rates of chronic irradiation evaluated within models of these four major hematopoietic lineages coincides with the real minimal dose rate of lethal chronic irradiation. The demonstrated ability of the models of the human thrombocytopoietic, lymphocytopoietic, granulocytopoietic, and erythropoietic systems to predict the dynamical response of these systems to acute/chronic irradiation in wide ranges of doses and dose rates implies that these mathematical models form an universal tool for the investigation and prediction of the dynamics of the major human hematopoietic lineages for a vast pattern of irradiation scenarios. In particular, these models could be applied for the radiation risk assessment for health of astronauts exposed to space radiation during long-term space missions, such as voyages to Mars or Lunar colonies, as well as for health of people exposed to acute/chronic irradiation due to environmental radiological events.

    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.

    Blood pressure (BP) elevations may correspond to different clinical situations. Hypertensives emergencies are situations that require immediate reduction in BP because of acute or rapidly progressing target organ damage: accelerated malignant hypertension, hypertensive encephalopathy, acute myocardial infarction, acute aortic dissection, acute left ventricular failure, and eclampsia. Hypertensive urgencies are those with marked elevated BP in which it is desirable to reduce BP progressively within few hours, such as severe hypertension, progressive target organ damage, perioperative hypertension. Cerebrovascular accidents have to be individualized. In most patients in the immediate post-stroke period, BP should not be lowered. Caution is advised in lowering BP in these patients because excessive falls may precipitate cerebral ischemia. In situations without symptoms or progressive target organ it is necessary to exclude proximate causes of elevated BP such as pain and elevated BP alone rarely requires antihypertensive treatment. Among parenteral antihypertensive (AH) drugs labetalol, nicardipine, urapidil, and nitroprussiate are generally used, and the choice of AH drug depends on the clinical situation. It is not required to normalize BP immediately but to reduce mean BP no more than 25%, then toward 160/100 mmHg as recommended by JNC VI, in order to avoid an impairment of renal, cerebral or coronary ischemia. Oral long-acting dihydropyridines are often subsequently administrated, except in myocardial ischemia. Therapeutic attitudes vary considerably according to the clinical situation: abstention, immediate decrease or progressive decrease in BP have to be decided. PMID:11190294

    We report this rare case of a 27-year-old man who presented with acute hepatitis E and went on to develop acute epigastric pain. He was diagnosed to have acute severe pancreatitis with shock and acute renal failure due to hepatitis E. Such a phenomenon has rarely been reported in the literature, with patients following a benign course and complete recovery after conservative management and analgesia. Awareness of this potentially life-threatening complication, especially in young men from endemic areas with acute hepatitis E presenting with abdomen pain has been highlighted. PMID:24899005

    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.

    This is a case of a pregnant lady at 8 weeks of gestation, who presented with acute abdomen. She was initially diagnosed with ruptured ectopic pregnancy and ruptured corpus luteal cyst as the differential diagnosis. However she then, was finally diagnosed as acute hemorrhagic pancreatitis with spontaneous complete miscarriage. This is followed by review of literature on this topic. Acute pancreatitis in pregnancy is not uncommon. The emphasis on high index of suspicion of acute pancreatitis in women who presented with acute abdomen in pregnancy is highlighted. Early diagnosis and good supportive care by multidisciplinary team are crucial to ensure good maternal and fetal outcomes. PMID:25628906

    Dyspnea is the predominant symptom for patients with acute heart failure and initial treatment is largely directed towards the alleviation of this. Contrary to conventional belief, not all patients present with fluid overload and the approach to management is rapidly evolving from a solitary focus on diuresis to one that more accurately reflects the complex interplay of underlying cardiac dysfunction and acute precipitant. Effective treatment thus requires an understanding of divergent patient profiles and an appreciation of various therapeutic options for targeted patient stabilization. The key principle within this paradigm is directed management that aims to diminish the work of breathing through situation appropriate ventillatory support, volume reduction and hemodynamic improvement. With such an approach, clinicians can more efficiently address respiratory discomfort while reducing the likelihood of avoidable harm. PMID:24223323

  1. Acute Biliary Septic Shock

    PubMed Central

    1990-01-01

    Forty-seven cases of biliary tract infection with septic shock are presented. The sepsis was caused by empyema of the gallbladder in 23 cases and by cholangitis in the remainder. Gallstones were most frequently the cause of the sepsis. An appropriate diagnostic description of the syndrome of biliary tract infection and septic shock should therefore include a description of the underlying biliary disease as well as the term acute biliary shock. In this series, emergency surgical management by removal of gallstones and drainage of suppuration was felt to be the most appropriate treatment. There was a high incidence of gallbladder rupture (10.6%) and intrahepatic stones (53.2%). Of the 13 patients who died, 8 might have survived if early operation had been performed after the diagnosis of acute biliary septic shock was established. PMID:2278914

    2016-01-01

    Acute aortic syndrome (AAS) is a term used to describe a constellation of life-threatening aortic diseases that have similar presentation, but appear to have distinct demographic, clinical, pathological and survival characteristics. Many believe that the three major entities that comprise AAS: aortic dissection (AD), intramural hematoma (IMH) and penetrating aortic ulcer (PAU), make up a spectrum of aortic disease in which one entity may evolve into or coexist with another. Much of the confusion in accurately classifying an AAS is that they present with similar symptoms: typically acute onset of severe chest or back pain, and may have similar radiographic features, since the disease entities all involve injury or disruption of the medial layer of the aortic wall. The accurate diagnosis of an AAS is often made at operation. This manuscript will attempt to clarify the similarities and differences between AD, IMH and PAU of the ascending aorta and describe the challenges in distinguishing them from one another.

    Acute aortic syndrome is the common denominator for acute events to the aortic wall and encompasses dissection of the aorta, intramural hematoma, formation of aortic ulcers and trauma to the aorta with an annual incidence of up to 35 cases/100.000 between 65 and 75 years of age. Both, inflammation and/or microtrauma at the level of the aortic media layer, and a genetic disposition are promoting elements of AAS, while the extent and anatomic involvement of the ascending aorta call for either surgical resection/repair in the proximal part of the aorta, or an endovascular solution for pathologies in the distal aorta; in all cases of dissection (regardless of location) reconstruction/realignment has been proven to portend better long-term outcomes (in addition to medical management of blood pressure).

    Acute ischemic stroke (AIS) is the leading cause of disability worldwide and among the leading causes of mortality. Although intravenous tissue plasminogen activator (IV-rtPA) was approved nearly 2 decades ago for treatment of AIS, only a minority of patients receive it due to a narrow time window for administration and several contraindications to its use. Endovascular approaches to recanalization in AIS developed in the 1980s, and recently, 5 major randomized trials showed an overwhelming superior benefit of combining endovascular mechanical thrombectomy with IV-rtPA over IV-rtPA alone. In this paper, we discuss the evolution of catheter-based treatment from first-generation thrombectomy devices to the game-changing stent retrievers, results from recent trials, and the evolving stroke systems of care to provide timely access to acute stroke intervention to patients in the United States.

    Acute pharyngitis/tonsillitis, which is characterized by inflammation of the posterior pharynx and tonsils, is a common disease. Several viruses and bacteria can cause acute pharyngitis; however, Streptococcus pyogenes (also known as Lancefield group A β-hemolytic streptococci) is the only agent that requires an etiologic diagnosis and specific treatment. S. pyogenes is of major clinical importance because it can trigger post-infection systemic complications, acute rheumatic fever, and post-streptococcal glomerulonephritis. Symptom onset in streptococcal infection is usually abrupt and includes intense sore throat, fever, chills, malaise, headache, tender enlarged anterior cervical lymph nodes, and pharyngeal or tonsillar exudate. Cough, coryza, conjunctivitis, and diarrhea are uncommon, and their presence suggests a viral cause. A diagnosis of pharyngitis is supported by the patient's history and by the physical examination. Throat culture is the gold standard for diagnosing streptococcus pharyngitis. However, it has been underused in public health services because of its low availability and because of the 1- to 2-day delay in obtaining results. Rapid antigen detection tests have been used to detect S. pyogenes directly from throat swabs within minutes. Clinical scoring systems have been developed to predict the risk of S. pyogenes infection. The most commonly used scoring system is the modified Centor score. Acute S. pyogenes pharyngitis is often a self-limiting disease. Penicillins are the first-choice treatment. For patients with penicillin allergy, cephalosporins can be an acceptable alternative, although primary hypersensitivity to cephalosporins can occur. Another drug option is the macrolides. Future perspectives to prevent streptococcal pharyngitis and post-infection systemic complications include the development of an anti-Streptococcus pyogenes vaccine. PMID:25229278

    Acute tubulointerstitial nephritis (TIN) is a frequent cause of acute renal failure, characterised by the presence of inflammatory cell infiltrate in the interstitium of the kidney. Immuno-allergic reaction to certain medications, mainly non-steroidal anti-inflammatory drugs and antibiotics are by far the most important etiology for TIN today, but other situations such as infections, toxins, and vasculitis are known to induce TIN. Incidence of TIN is increasing, probably due to prescription habits and NSAID overuse, representing 3-7% of acute kidney injury in biopsies in children. Avoidance of the causal substance and rapid steroid therapy are hallmarks for patient care, but spontaneous initial recovery is very frequent and the general prognosis seems satisfactory. However, development of chronic TIN, without response to steroid or other immunosuppressive treatment, is possible. As the largest part of TIN is secondary to certain drugs, clear indications in particular for NSAID or antibiotics should be respected to reduce the number of TIN cases. PMID:21638156

    The first report of acute respiratory distress syndrome (ARDS) was published in 1967, and even now acute lung injury (ALI) and ARDS are severe forms of diffuse lung disease that impose a substantial health burden all over the world. Recent estimates indicate approximately 190,000 cases per year of ALI in the United States each year, with an associated 74,500 deaths per year. Common causes of ALI/ARDS are sepsis, pneumonia, trauma, aspiration pneumonia, pancreatitis, and so on. Several pathologic stages of ALI/ARDS have been described: acute inflammation with neutrophil infiltration, fibroproliferative phase with hyaline membranes, with varying degrees of interstitial fibrosis, and resolution phase. There has been intense investigation into the pathophysiologic events relevant to each stage of ALI/ARDS, and much has been learned in the alveolar epithelial, endobronchial homeostasis, and alveolar cell immune responses, especially neutrophils and alveolar macrophages in an animal model. However, these effective results in the animal models are not equally adoptive to those in randomized, controlled trials. The clinical course of ALI/ARDS is variable with the likely pathophysiologic complexity of human ALI/ARDS. In 1994, the definition was recommended by the American-European Consensus Conference Committee, which facilitated easy nomination of patients with ALI/ARDS for a randomized, clinical trial. Here, we review the recent randomized, clinical trials of ALI/ARDS. PMID:19420806

    Epispadias and exstrophy of the cloaca, also known as OEIS complex (omphalocele, exstrophy, imperforate anus, spinal defects), respectively constitute the most benign and severe ends of the bladder exstrophy-epispadias complex (BEEC) spectrum. In 2009, El-Hattab et al. reported the first patient with OEIS complex associated with a chromosome 1p36 deletion. Here we report a second patient with 1p36 deletion who also has classic bladder exstrophy, supporting the possible role of genes in this region in the development of BEEC. The absence of omphalocele and imperforate anus in our patient places him toward classic bladder exstrophy while presence of spina bifida and the absence of coccyx suggest an overlap with OEIS complex. An additional differential diagnosis is the pentalogy of Cantrell in our patient as he also has a diaphragmatic hernia and an incomplete sternum. This is the second observation of a ventral midline birth defect in association with 1p36 deletion syndrome, following El-Hattab et al.'s report [2009]. The three genes (NOCL2, DVL1, and MMP23B) discussed as possible candidates are also among the deleted ones in our patient, supporting the possible role of these genes in BEEC spectrum. © 2016 Wiley Periodicals, Inc.

    AIM: To develop a novel non-sequencing method for the detection of hepatitis B virus (HBV) pre-S deletion mutants in HBV carriers. METHODS: The entire region of HBV pre-S1 and pre-S2 was amplified by polymerase chain reaction (PCR). The size of PCR products was subsequently determined by capillary gel electrophoresis (CGE). CGE were carried out in a PACE-MDQ instrument equipped with a UV detector set at 254 nm. The samples were separated in 50 μm ID eCAP Neutral Coated Capillaries using a voltage of 6 kV for 30 min. Data acquisition and analysis were performed using the 32 Karat Software. A total of 114 DNA clones containing different sizes of the HBV pre-S gene were used to determine the accuracy of the CGE method. One hundred and fifty seven hepatocellular carcinoma (HCC) and 160 non-HCC patients were recruited into the study to assess the association between HBV pre-S deletion and HCC by using the newly-established CGE method. Nine HCC cases with HBV pre-S deletion at the diagnosis year were selected to conduct a longitudinal observation using serial serum samples collected 2-9 years prior to HCC diagnosis. RESULTS: CGE allowed the separation of PCR products differing in size > 3 bp and was able to identify 10% of the deleted DNA in a background of wild-type DNA. The accuracy rate of CGE-based analysis was 99.1% compared with the clone sequencing results. Using this assay, pre-S deletion was more frequently found in HCC patients than in non-HCC controls (47.1% vs 28.1%, P < 0.001). Interestingly, the increased risk of HCC was mainly contributed by the short deletion of pre-S. While the deletion ≤ 99 bp was associated with a 2.971-fold increased risk of HCC (95%CI: 1.723-5.122, P < 0.001), large deletion (> 99 bp) did not show any association with HCC (P = 0.918, OR = 0.966, 95%CI: 0.501-1.863). Of the 9 patients who carried pre-S deletions at the stage of HCC, 88.9% (8/9) had deletions 2-5 years prior to HCC, while only 44.4%4 (4/9) contained such deletions 6-9 years prior to HCC. CONCLUSION: CGE is a sensitive approach for HBV pre-S deletion analysis. Pre-S deletion, especially for short DNA fragment deletion, is a useful predictive marker for HCC. PMID:25309088

    Objective: To identify a causative variant(s) that may contribute to Alzheimer disease (AD) in African Americans (AA) in the ATP-binding cassette, subfamily A (ABC1), member 7 (ABCA7) gene, a known risk factor for late-onset AD. Methods: Custom capture sequencing was performed on ∼150 kb encompassing ABCA7 in 40 AA cases and 37 AA controls carrying the AA risk allele (rs115550680). Association testing was performed for an ABCA7 deletion identified in large AA data sets (discovery n = 1,068; replication n = 1,749) and whole exome sequencing of Caribbean Hispanic (CH) AD families. Results: A 44-base pair deletion (rs142076058) was identified in all 77 risk genotype carriers, which shows that the deletion is in high linkage disequilibrium with the risk allele. The deletion was assessed in a large data set (531 cases and 527 controls) and, after adjustments for age, sex, and APOE status, was significantly associated with disease (p = 0.0002, odds ratio [OR] = 2.13 [95% confidence interval (CI): 1.42–3.20]). An independent data set replicated the association (447 cases and 880 controls, p = 0.0117, OR = 1.65 [95% CI: 1.12–2.44]), and joint analysis increased the significance (p = 1.414 × 10−5, OR = 1.81 [95% CI: 1.38–2.37]). The deletion is common in AA cases (15.2%) and AA controls (9.74%), but in only 0.12% of our non-Hispanic white cohort. Whole exome sequencing of multiplex, CH families identified the deletion cosegregating with disease in a large sibship. The deleted allele produces a stable, detectable RNA strand and is predicted to result in a frameshift mutation (p.Arg578Alafs) that could interfere with protein function. Conclusions: This common ABCA7 deletion could represent an ethnic-specific pathogenic alteration in AD. PMID:27231719

    Approximately 6% of school-aged children have math difficulties (MD). A neurogenetic etiology has been suggested due to the presence of MD in some genetic syndromes such as 22q11.2DS. However, the contribution of 22q11.2DS to the MD phenotype has not yet been investigated. This is the first population-based study measuring the frequency of 22q11.2DS among school children with MD. Children (1,564) were identified in the schools through a screening test for language and math. Of these children, 152 (82 with MD and 70 controls) were selected for intelligence, general neuropsychological, and math cognitive assessments and for 22q11.2 microdeletion screening using MLPA. One child in the MD group had a 22q11.2 deletion spanning the LCR22-4 to LCR22-5 interval. This child was an 11-year-old girl with subtle anomalies, normal intelligence, MD attributable to number sense deficit, and difficulties in social interactions. Only 19 patients have been reported with this deletion. Upon reviewing these reports, we were able to characterize a new syndrome, 22q11.2 DS (LCR22-4 to LCR22-5), characterized by prematurity; pre- and postnatal growth restriction; apparent hypotelorism, short/upslanting palpebral fissures; hypoplastic nasal alae; pointed chin and nose; posteriorly rotated ears; congenital heart defects; skeletal abnormalities; developmental delay, particularly compromising the speech; learning disability (including MD, in one child); intellectual disability; and behavioral problems. These results suggest that 22q11.2 DS (LCR22-4 to LCR22-5) may be one of the genetic causes of MD. PMID:24989330

    Patients with 2q37 deletions manifest brachydactyly mental retardation syndrome (BDMR). Recent advances in human molecular research have revealed that alterations in the histone deacetylase 4 gene (HDAC4) are responsible for the clinical manifestations of BDMR. Here, we report two male patients with 2q37.3 deletions. One of the patients showed a typical BDMR phenotype, and HDAC4 was included in the deletion region. HDAC4 was preserved in the other patient, and he showed a normal intelligence level with the delayed learning of complex motor skills. Detailed neuropsychological examinations revealed similar neuropsychological profiles in these two patients (visuo-spatial dyspraxia) that suggested developmental dyspraxia. These observations suggested that some other candidate genes for neuronal development exist in the telomeric region of HDAC4. PMID:25329715

    Copy number variation (CNV) has been associated with a variety of neuropsychiatric disorders, including intellectual disability/developmental delay (ID/DD), autism spectrum disorder (ASD), and schizophrenia (SCZ). Often, individuals carrying the same pathogenic CNV display high clinical variability. By array-CGH analysis, we identified a novel familial 3q29 deletion (1.36 Mb), centromeric to the 3q29 deletion region, which manifests with variable expressivity. The deletion was identified in a 3-year-old girl diagnosed with ID/DD and autism and segregated in six family members, all affected by severe psychiatric disorders including schizophrenia, major depression, anxiety disorder, and personality disorder. All individuals carrying the deletion were overweight or obese, and anomalies compatible with optic atrophy were observed in three out of four cases examined. Amongst the 10 genes encompassed by the deletion, the haploinsufficiency of Optic Atrophy 1 (OPA1), associated with autosomal dominant optic atrophy, is likely responsible for the ophthalmological anomalies. We hypothesize that the haploinsufficiency of ATPase type 13A4 (ATP13A4) and/or Hairy/Enhancer of Split Drosophila homolog 1 (HES1) contribute to the neuropsychiatric phenotype, while HES1 deletion might underlie the overweight/obesity. In conclusion, we propose a novel contiguous gene syndrome due to a proximal 3q29 deletion variably associated with autism, ID/DD, psychiatric traits and overweight/obesity. PMID:26620927

    Acute acalculous cholecystitis is a relatively rare but potentially lethal condition if not treated promptly. Since stones are not present, diagnostic procedures such as ultrasound or other radiological procedures are frequently not helpful. Tc-99m iminodiacetic acid scan results were analyzed in 11 proven cases of acute acalculous cholecystitis. All had positive tests with nonvisualization of the gallbladder giving a sensitivity of 100%. Tc-99m iminodiacetic acid cholescintigraphy is a highly reliable test and is easily performed even in acutely ill patients and should be the test of choice in all patients predisposed to and suspected of acute acalculous cholecystitis.

    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.

    The nature and extent of the acute injury due to toxic inhalants depend on the inhalant's solubility in water pH and chemical reactivity, on the aerodynamic diameter of particles (when the inhalant is an aerosol), and on the degree of exposure. Initial signs and symptoms indicate upper airways and bronchial irritation. Laryngeal oedema and (or) severe bronchospasm may be rapidly lethal. After cessation of exposure a transient improvement is generally observed; however a delayed pulmonary oedema may occur within the first 48 hours. On the following days, bacterial surinfection is a common complication. Possible long-term sequelae are reactive airways dysfunction syndrome and bronchiolitis obliterans. PMID:9781191

    Acute compartment syndrome (ACS) is a well-known pathophysiologic complication of trauma or tissue ischemia. ACS affects the appearance, function, and even the viability of the involved limb, and demands immediate diagnosis and treatment. However, ACS is difficult to diagnose and the only effective treatment is decompressive surgical fasciotomy. The clinical signs and symptoms may easily be attributed to other aspects of the injury, which further complicates the diagnosis. This article highlights the latest information regarding the diagnosis of ACS, how to perform fasciotomies, how to manage fasciotomy wounds, and also reviews complications and outcomes of ACS.

    Acute interstitial pneumonia (AIP) of feedlot cattle is a sporadically occurring respiratory condition that is often fatal. Affected cattle have a sudden onset of labored breathing. There is no confirmed effective treatment of feedlot AIP; however, administration of antibiotics effective against common bacterial respiratory pathogens and nonsteroidal anti-inflammatory drugs, especially aspirin, has been recommended. Protective strategies are not well defined, but efforts to limit dust exposure and heat stress; to ensure consistent formulation, mixing, and delivery of feed; and to identify and treat infectious respiratory disease in a timely manner may decrease rates of feedlot AIP.

    Alcoholic hepatitis (AH) causes great morbidity and mortality in the United States and throughout the world. Advances in therapy have proven difficult. In part, this reflects challenges in diagnosis, including the distinction between AH and acute-on-chronic liver failure. Liver biopsy is the best method to clarify the cause in circumstances whereby conflicting clinical data confound the diagnosis. All treatment of AH begins with abstinence from alcohol. All patients with AH should be given sufficient nutrition. Prednisolone has become the principal agent for treating patients with severe AH. PMID:27373613

    Acute kidney injury (AKI) is a global public health concern associated with high morbidity, mortality, and healthcare costs. Other than dialysis, no therapeutic interventions reliably improve survival, limit injury, or speed recovery. Despite recognized shortcomings of in vivo animal models, the underlying pathophysiology of AKI and its consequence, chronic kidney disease (CKD), is rich with biological targets. We review recent findings relating to the renal vasculature and cellular stress responses, primarily the intersection of the unfolded protein response, mitochondrial dysfunction, autophagy, and the innate immune response. Maladaptive repair mechanisms that persist following the acute phase promote inflammation and fibrosis in the chronic phase. Here macrophages, growth-arrested tubular epithelial cells, the endothelium, and surrounding pericytes are key players in the progression to chronic disease. Better understanding of these complex interacting pathophysiological mechanisms, their relative importance in humans, and the utility of biomarkers will lead to therapeutic strategies to prevent and treat AKI or impede progression to CKD or end-stage renal disease (ESRD).

    2015-02-01

    Inaugural traumatic patellar dislocation is most often due to trauma sustained during physical or sports activity. Two-thirds of acute patellar dislocations occur in young active patients (less than 20 years old). Non-contact knee sprain in flexion and valgus is the leading mechanism in patellar dislocation, accounting for as many as 93% of all cases. The strong displacement of the patella tears the medial stabilizing structures, and notably the medial patellofemoral ligament (MPFL), which is almost always injured in acute patellar dislocation, most frequently at its femoral attachment. Lateral patellar glide can be assessed with the knee in extension or 20° flexion. Displacement by more than 50% of the patellar width is considered abnormal and may induce apprehension. Plain X-ray and CT are mandatory to diagnose bony risk factors for patellar dislocation, such as trochlear dysplasia or increased tibial tubercle-trochlear groove distance (TT-TG), and plan correction. MRI gives information on cartilage and capsulo-ligamentous status for treatment planning: free bodies or osteochondral fracture have to be treated surgically. If patellar dislocation occurs in an anatomically normal knee and osteochondral fracture is ruled out on MRI, non-operative treatment is usually recommended. PMID:25592052

    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 ischemic stroke is common and often treatable, but treatment requires reliable information on the state of the brain that may be provided by modern neuroimaging. Critical information includes: the presence of hemorrhage; the site of arterial occlusion; the size of the early infarct "core"; and the size of underperfused, potentially threatened brain parenchyma, commonly referred to as the "penumbra." In this chapter we review the major determinants of outcomes in ischemic stroke patients, and the clinical value of various advanced computed tomography and magnetic resonance imaging methods that may provide key physiologic information in these patients. The focus is on major strokes due to occlusions of large arteries of the anterior circulation, the most common cause of a severe stroke syndrome. The current evidence-based approach to imaging the acute stroke patient at the Massachusetts General Hospital is presented, which is applicable for all stroke types. We conclude with new information on time and stroke evolution that imaging has revealed, and how it may open the possibilities of treating many more patients. PMID:27432672

    Acute promyelocytic leukemia (APL) is a subtype of acute myelogenous leukemia frequently associated with disseminated intravascular coagulation (DIC). Data on 11 patients with APL treated at our institution were analyzed and compared with those of 147 published cases. Most had a bleeding diathesis at presentation and evidence of DIC eventually developed in all. Seven patients (64%) showed the t(15;17)(q22;q21) karyotype or a similar translocation. Using a chemotherapy induction regimen containing an anthracycline, complete remission, requiring a total of 14 courses of treatment, was achieved in six patients (55%). The median duration of response and median survival for complete responders were 10 and 15 months, respectively. Three patients (27%) died of bleeding complications during induction therapy. The tritiated-thymidine labeling index of leukemia cells predicted which patients would achieve a complete remission. Review of six studies of 147 patients with APL from the past 12 years supports the use of a chemotherapy induction regimen containing anthracycline or amsacrine and heparin for the treatment of DIC.

    Acute pyelonephritis is one of the most serious bacterial illnesses during childhood. Escherichia coli is responsible in most cases, however other organisms including Klebsiella, Enterococcus, Enterobacter, Proteus, and Pseudomonas species are being more frequently isolated. In infants, who are at major risk of complications such as sepsis and meningitis, symptoms are ambiguous and fever is not always useful in identifying those at high risk. A diagnosis of acute pyelonephritis is initially made on the basis of urinalysis; dipstick tests for nitrites and/or leukocyte esterase are the most accurate indicators of infection. Collecting a viable urine sample for urine culture using clean voided methods is feasible, even in young children. No gold standard antibiotic treatment exists. In children appearing well, oral therapy and outpatient care is possible. New guidelines suggest less aggressive imaging strategies after a first infection, reducing radiation exposure and costs. The efficacy of antibiotic prophylaxis in preventing recurrence is still a matter of debate and the risk of antibiotic resistance is a warning against its widespread use. Well-performed randomized controlled trials are required in order to better define both the imaging strategies and medical options aimed at preserving long-term renal function. PMID:26238274

    Appendiceal disease can be acute, acute recurrent, or chronic. Acute appendicitis is the most common form. Acute recurrent appendicitis is more common than chronic appendicitis. In children the clinical manifestations of appendicitis are variable. Patients who have an appendicolith usually develop appendicitis, often with perforation. A case is presented of 3-year follow-up of a patient with an appendicolith and acute recurrent appendicitis. The literature about appendicoliths is reviewed. In the appropriate clinical setting, a history of prior episodes of similar right lower quadrant pain does not preclude the diagnosis of appendiceal disease. Awareness of the less common forms of appendicitis is important so that appropriate treatment is not delayed. PMID:3052484

    Introduction Acute chikungunya (CHIKV) is predominantly an acute onset of excruciatingly painful, self-limiting musculoskeletal (MSK) arbovirus illness and this was further reported by us during the 2006 Indian epidemic [Chopra et al. Epidemiol Infect 2012]. Selected serum cytokines profile in subjects within one month of onset of illness is being presented. Methods Out of 509 clinical CHIKV cases (43% population) identified during a rural population survey, 225 subjects consented blood investigations. 132 examined within 30 days of febrile onset are the study cohort. Anti-CHIKV IgM and IgG antibodies tested by immunochromatography and indirect immunofluorescence respectively. Interferons (IFN)-α, -β and -γ, Interferon Gamma-Induced Protein-10 (CXCL-10/IP-10), Tumor Necrosis Factor-α (TNF-α), Interleukin-1β (IL-1β), Interleukin-6 (IL-6), Interleukin-13 (IL-13), Monocyte Chemoattractant Protein-1 (MCP-1), Interleukin–4 (IL-4) and Interleukin–10 (IL-10) performed by ELISA. Samples collected from neighboring community a year prior to the epidemic used as healthy controls. Results Seropositivity for anti-CHIKV IgM and IgG was 65% and 52% respectively. IFN-α, IFN-β, IFN-γ, CXCL10/IP-10 and IL-1β showed intense response in early acute phase. Cytokines (particularly TNF-α, MCP-1, IL-4, IL-6 and IL-10) was maximum in extended symptomatic phase and remained elevated in recovered subjects. Higher (p<0.05) IFN and IL-4 seen in patients seropositive for anti-CHIKV IgG. Elderly cases (≥65 years) showed elevated cytokines (except IFN) and anti-CHIKV antibodies near similar to younger subjects. Significant correlations (p<0.05) found between cytokines and clinical features (fatigue, low back ache, myalgia) and anti-CHIKV antibodies. Conclusion An intense cytokine milieu was evident in the early and immediate persistent symptomatic phase and in recovered subjects. Early persistent IgM and lower IgG to anti-CHKV and intense Th2 cytokine phenotype seem to be

    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

    2009-12-01

    Socially disadvantaged Indigenous infants and children living in western industrialized countries experience high rates of infectious diarrhea, no more so than Aboriginal children from remote and rural regions of Northern Australia. Diarrheal disease, poor nutrition, and intestinal enteropathy reflect household crowding, inadequate water and poor sanitation and hygiene. Acute episodes of watery diarrhea are often best managed by oral glucose-electrolyte solutions with continuation of breastfeeding and early reintroduction of feeding. Selective use of lactose-free milk formula, short-term zinc supplementation and antibiotics may be necessary for ill children with poor nutrition, persistent symptoms, or dysentery. Education, high standards of environmental hygiene, breastfeeding, and immunization with newly licensed rotavirus vaccines are all needed to reduce the unacceptably high burden of diarrheal disease encountered in young children from Indigenous communities.

    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

    Summary Acute lymphoblastic leukaemia (ALL) is seen in both children and adults, but its incidence peaks between ages 2 and 5 years. The causation of ALL is considered to be multi-factorial, including exogenous or endogenous exposures, genetic susceptibility, and chance. The survival rate of paediatric ALL has improved to approximately 90% in recent trials with risk stratification by biologic features of leukaemic cells and response to therapy, therapy modification based on patient pharmacodynamics and pharmacogenomics, and improved supportive care. However, innovative approaches are needed to further improve survival while reducing adverse effects. While most children can be cured, the prognosis of infants and adults with ALL remains poor. Recent genome-wide profiling of germline and leukaemic cell DNA has identified novel submicroscopic structural genetic alterations and sequence mutations that contribute to leukaemogenesis, define new ALL subtypes, influence responsiveness to treatment, and may provide novel prognostic markers and therapeutic targets for personalized medicine.

    Inhaled substances may cause injury in pulmonary epithelium at various levels of respiratory tract, leading from simple symptoms to severe disease. Acute inhalation injury (AII) is not uncommon condition. There are certain high risk groups but AII may occur at various places including home or workplace. Environmental exposure is also possible. In addition to individual susceptibility, the characteristics of inhaled substances such as water solubility, size of substances and chemical properties may affect disease severity as well as its location. Although AII cases may recover in a few days but AII may cause long-term complications, even death. We aimed to discuss the effects of short-term exposures (minutes to hours) to toxic substances on the lungs. PMID:25610115

    Arsenic poisonings are still important in the field of toxicology, though they are not as frequent as about 20-30 years ago. In this paper, the arsenic concentrations in ante- and post-mortem materials, and also forensic and anatomo-pathological aspects in three cases of massive acute poisoning with arsenic(III) oxide (two of them with unexplained criminalistic background, in which arsenic was taken for amphetamine and one suicide), are presented. Ante-mortem blood and urine arsenic concentrations ranged from 2.3 to 6.7 microg/ml, respectively. Post-mortem tissue total arsenic concentrations were also detected in large concentrations. In case 3, the contents of the duodenum contained as much as 30.1% arsenic(III) oxide. The high concentrations of arsenic detected in blood and tissues in all presented cases are particularly noteworthy in that they are very rarely detected at these concentrations in fatal arsenic poisonings.

    Acute upper gastrointestinal bleeding (AUGIB) is a frequently encountered medical emergency with an incidence of 84-160/100000 and associated with mortality of approximately 10%. Guidelines from the National Institute for Care and Care Excellence outline key features in the management of AUGIB. Patients require prompt resuscitation and risk assessment using validated tools. Upper gastrointestinal endoscopy provides accurate diagnosis, aids in estimating prognosis and allows therapeutic intervention. Endoscopy should be undertaken immediately after resuscitation in unstable patients and within 24 hours in all other patients. Interventional radiology may be required for bleeding unresponsive to endoscopic intervention. Drug therapy depends on the cause of bleeding. Intravenous proton pump inhibitors should be used in patients with high-risk ulcers. Terlipressin and broad-spectrum antibiotics should be used following variceal haemorrhage. Hospitals admitting patients with AUGIB need to provide well organised services and ensure access to relevant services for all patients, and particularly to out of hours endoscopy. PMID:26430191

    The authors report on three patients with acute retinal necrosis who were treated with the virostatic agent Acyclovir and who underwent vitreoretinal surgery with silicone oil filling for total retinal detachment. In two eyes the retina was reattached, but useful vision was only preserved in one patient. Titers from blood and the vitreous, as well as microscopic findings in retinal biopsies, support the view that the necrosis is caused by a herpes simplex virus infection. After therapy with Acyclovir was instituted no further progression on the necrosis was observed. However, the development of retinal detachment could not be prevented. Early diagnosis and antiviral therapy are essential to improve the otherwise poor prognosis in this rare syndrome. PMID:3221657

    The author presents the clinical history of 14 patients, from 21 to 48 years of age, 10 men and 4 women, with a final diagnosis of acute epiglottitis who were hospitalized at Gorgas Army Hospital or at the San Fernando Clinic. All the patients had pharyngitis and dysphagia, a few with nasal voice, stridor and difficulty breathing, as the chief complaint. All the patients were initially intubated orally for diagnostic purposes and immediately after nasotracheal intubation was done until the patient improved in 2 or 3 days (one patient remained intubated for 5 days). All patients were kept in the Intensive Care Unit and were treated with Ampicillin and Chloramphenicol IV and lately with a second generation cephalosporin (Cefamandole). The patients allergic to Penicillin were treated with Clindamycin and Chloramphenicol. Corticosteroids were not used in any of the patients. There were no sequelae and none of the patients expired.

    The objective of this study was to characterize the acute clinical effects, laboratory findings, complications, and disposition of patients presenting to the hospital after abusing synthetic cathinone. We conducted a retrospective multicenter case series of patients with synthetic cathinone abuse by searching for the terms bath salts, MDPV, methylenedioxypyrovalerone, mephedrone, methcathinone, methylone, methedrone, and cathinone within the "agent" field of a national clinical toxicology database (ToxIC). The medical records of these patients were obtained and abstracted by investigators at each study site. Patients with confirmatory testing that identified a synthetic cathinone in either blood or urine were included in the series. Patients who had either an undetectable synthetic cathinone test or no confirmatory testing were excluded. A data abstraction sheet was used to obtain information on each patient. We entered data into an Excel spreadsheet and calculated descriptive statistics. We identified 23 patients with confirmed synthetic cathinone exposure--all were positive for methylenedioxyprovalerone (MDPV). Eighty-three percent were male and 74 % had recreational intent. The most common reported clinical effects were tachycardia (74 %), agitation (65 %), and sympathomimetic syndrome (65 %). Acidosis was the most common laboratory abnormality (43 %). Seventy-eight percent of patients were treated with benzodiazepines and 30 % were intubated. Ninety-six percent of patients were hospitalized and 87 % were admitted to the ICU. The majority (61 %) of patients was discharged home but 30 % required inpatient psychiatric care. There was one death in our series. The majority of patients presenting to the hospital after abusing MDPV have severe sympathomimetic findings requiring hospitalization. A number of these patients require inpatient psychiatric care after their acute presentation. PMID:25468313

    2011-01-01

    Introduction About 10% of adults have suffered an attack of asthma, and up to 5% of these have severe disease that responds poorly to treatment. Patients with severe disease have an increased risk of death, but patients with mild to moderate disease are also at risk of exacerbations. Most guidelines about the management of asthma follow stepwise protocols. This review does not endorse or follow any particular protocol, but presents the evidence about specific interventions. Methods and outcomes We conducted a systematic review and aimed to answer the following clinical question: What are the effects of treatments for acute asthma? We searched: Medline, Embase, The Cochrane Library, and other important databases up to April 2010 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). Results We found 100 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. Conclusions In this systematic review we present information relating to the effectiveness and safety of the following interventions: beta2 agonists (plus ipratropium bromide, pressured metered-dose inhalers, short-acting continuous nebulised, short-acting intermittent nebulised, short-acting iv, and inhaled formoterol); corticosteroids (inhaled); corticosteroids (single oral, combined inhaled, and short courses); education about acute asthma; generalist care; helium–oxygen mixture (heliox); magnesium sulphate (iv and adding isotonic nebulised magnesium to inhaled beta2 agonists); mechanical ventilation; oxygen supplementation (controlled 28% oxygen and controlled 100% oxygen); and specialist care.

    Acromioclavicular dislocations represent over 10% of acute traumatic injuries to the shoulder girdle. The mechanism is usually a direct impact on the shoulder with the arm in adduction, producing rupture of the acromioclavicular (AC) ligaments, then of the coracoclavicular (CC) ligament, with displacement of the lateral end of the clavicle. Rockwood described 6 grades of injury. Physical examination usually provides the diagnosis, which is confirmed by radiological examination. X-rays centered on the AC joint, if necessary with forceful adduction of both shoulders or under traction, are useful to evaluate the severity of the lesion. Grade I and II lesions are usually treated conservatively by simply immobilizing the arm for 3 to 4 weeks. Surgical treatment is usually advocated for grade IV, V and VI lesions: AC or CC fixation, sometimes associated with ligament repair, depending on the surgeons. AC pinning or C-C screw fixation are the techniques most often used. Management of grade III lesions remains controversial. Some authors advocate immediate surgical treatment in young, active patients, in heavy laborers and even in slender individuals. The choice of the operative technique is controversial, as no single technique has clearly proved to be superior to others. Other authors advocate conservative treatment, which gives functional results which patients consider quite acceptable, with faster recovery; patients should be informed that results are essentially similar, whatever the treatment. The possibility of performing secondary operations with good results in cases with failure of conservative management is a further argument in favor of applying conservative therapy first in acute injuries.

    Acute respiratory distress syndrome (ARDS) is an acute respiratory failure produced by an inflammatory edema secondary to increased lung capillary permeability. This causes alveolar flooding and subsequently deep hypoxemia, with intrapulmonary shunt as its most important underlying mechanism. Characteristically, this alteration is unresponsive to high FIO2 and only reverses with end-expiratory positive pressure (PEEP). Pulmonary infiltrates on CXR and CT are the hallmark, together with decreased lung compliance. ARDS always occurs within a week of exposition to a precipitating factor; most frequently pneumonia, shock, aspiration of gastric contents, sepsis, and trauma. In CT scan, the disease is frequently inhomogeneous, with gravitational infiltrates coexisting with normal-density areas and also with hyperaerated parenchyma. Mortality is high (30-60%) especially in ARDS associated with septic shock and neurocritical diseases. The cornerstone of therapy lies in the treatment of the underlying cause and in the use mechanical ventilation which, if inappropriately administered, can lead to ventilator-induced lung injury. Tidal volume = 6 ml/kg of ideal body weight to maintain an end-inspiratory (plateau) pressure = 30 cm H2O ("protective ventilation") is the only variable consistently associated with decreased mortality. Moderate-to-high PEEP levels are frequently required to treat hypoxemia, yet no specific level or titration strategy has improved outcomes. Recently, the use of early prone positioning in patients with PaO2/FIO2 = 150 was associated with increased survival. In severely hypoxemic patients, it may be necessary to use adjuvants of mechanical ventilation as recruitment maneuvers, pressure-controlled modes, neuromuscular blocking agents, and extracorporeal-membrane oxygenation. Fluid restriction appears beneficial. PMID:27576283

    Migraine is a brain disease whose principal symptom is episodic intense throbbing pain in the head which is often accompanied by photophobia, phonophobia, nausea and vomiting. Primary objectives of migraine treatment are to abort the acute attacks, treat associated symptoms and prevent future attacks. With a majority of migraine patients being young, they will need a treatment plan to suit their professional work, leisure and reproductive concerns. Non specific anti-migraine drugs like non-steroidal anti-inflammatory drugs, anti-emetics, narcotics, and sympathomimetics are usually helpful in mild to moderate attacks. Specific drugs like triptans and ergots are useful for moderate to severe attacks. In step care approach, the patients are started with the simplest options like simple analgesics first followed by non-steroidal agents, then ergot preparations and eventually triptans if they do not respond. In stratified care approach, the attacks and the patients are stratified according to the severity and therapeutic response. Those with severe disabling episodes are given specific anti-migraine medications like triptans whereas patients with mild or low disability are treated with simple analgesics. Currently, the most favored acute anti-migraine medication is a triptan. At marketed doses all triptans are effective as compared to placebos and generally well tolerated. Amongst them however, rizatriptan 10 mg, eletriptan 80 mg and almotriptan 12.5 mg provide the highest likelihood of consistent success. Triptan related adverse events are usually short lived, mild and clinically insignificant. Ergots are slowly being replaced by triptans. This is because of their adverse side-effects, low bioavailability and high potential for abuse that can lead to overuse headache. PMID:21049703

    Doxylamine succinate is an antihistaminic drugwith additional hypnotic, anticholinergic and local anesthetic effects first described in 1948. In Korea and many other countries, it is a common-over-the counter medication frequently involved in overdoses. Clinical symtomatology of doxylamine succinate overdose includes somnolence, coma, seizures, mydriasis, tachycardia, psychosis, and rhabdomyolysis. A serious complication may be rhabdomyolysis with subsequent impairment of renal function and acute renal failure. We report a case of acute renal failure and acute pancreatitis complicating a doxylamine succinate intoxication. PMID:12046971

    The present article analyses the main presentations on acute pancreatitis at Digestive Disease Week 2015. Arterial pseudoaneurysm is an uncommon complication of acute pancreatitis (incidence 0.7%) and mortality from this cause is currently anecdotal. Diabetes mellitus has little impact on the clinical course of acute pancreatitis, unlike cirrhosis, which doubles the risk of mortality. Intake of unsaturated fat could be associated with an increased severity of acute pancreatitis and is a confounding factor in studies evaluating the relationship between obesity and morbidity and mortality. PET-CT (positron emission tomography-computed tomography) could be a non-invasive tool to detect infection of collections in acute pancreatitis. Peripancreatic fat necrosis is less frequent than pancreatic fat necrosis and is associated with a better clinical course. If the clinical course is poor, increasing the calibre of the percutaneous drains used in the treatment of infected necrosis can avoid surgery in 20% of patients. The use of low molecular-weight heparin in moderate or severe pancreatitis could be associated with a better clinical course, specifically with a lower incidence of necrosis. In acute recurrent pancreatitis, simvastatin is a promising drug for prophylaxis of new episodes of acute pancreatitis. Nutritional support through a nasogastric tube does not improve clinical course compared with oral nutrition. PMID:26520203

    The care of patients with acutely decompensated heart failure is being reshaped by the availability and understanding of several novel and emerging heart failure biomarkers. The gold standard biomarkers in heart failure are B-type natriuretic peptide and N-terminal pro-B-type natriuretic peptide, which play an important role in the diagnosis, prognosis, and management of acute decompensated heart failure. Novel biomarkers that are increasingly involved in the processes of myocardial injury, neurohormonal activation, and ventricular remodeling are showing promise in improving diagnosis and prognosis among patients with acute decompensated heart failure. These include midregional proatrial natriuretic peptide, soluble ST2, galectin-3, highly-sensitive troponin, and midregional proadrenomedullin. There has also been an emergence of biomarkers for evaluation of acute decompensated heart failure that assist in the differential diagnosis of dyspnea, such as procalcitonin (for identification of acute pneumonia), as well as markers that predict complications of acute decompensated heart failure, such as renal injury markers. In this article, we will review the pathophysiology and usefulness of established and emerging biomarkers for the clinical diagnosis, prognosis, and management of acute decompensated heart failure.

    The review discusses existing evidence of benefits and risks of cerebrolysin--a mixture of low-molecular-weight peptides and amino acids derived from pigs' brain tissue with proposed neuroprotective and neurotrophic properties, for acute ischemic stroke. The review presents results of systematic search and analysis of randomised clinical trials comparing cerebrolysin with placebo in patients with acute ischemic stroke. Only one trial was selected as meeting quality criteria. No difference in death and adverse events between cerebrolysin and placebo was established. The authors conclude about insufficiency of evidence to evaluate the effect of cerebrolysin on survival and dependency in people with acute ischemic stroke. PMID:23805635

    A middle-aged man had deteriorated rapidly in hospital after being misdiagnosed with acute alcoholic hepatitis. Acute Legionnaires disease (Legionellosis) was subsequently diagnosed on rapid antigen urinary testing and further confirmed serologically. This led to appropriate antibiotic treatment and complete clinical resolution. Physicians caring for patients with alcohol-related liver disease should consider Legionella pneumophila in their differential diagnosis even with a paucity of respiratory symptoms. PMID:23355576

    2014-03-01

    Acute cardiogenic pulmonary edema and cardiogenic shock are two of the main forms of presentation of acute heart failure. Both entities are serious, with high mortality, and require early diagnosis and prompt and aggressive management. Acute pulmonary edema is due to the passage of fluid through the alveolarcapillary membrane and is usually the result of an acute cardiac episode. Correct evaluation and clinical identification of the process is essential in the management of acute pulmonary edema. The initial aim of treatment is to ensure hemodynamic stability and to correct hypoxemia. Other measures that can be used are vasodilators such as nitroglycerin, loop diuretics and, in specific instances, opioids. Cardiogenic shock is characterized by sustained hypoperfusion, pulmonary wedge pressure > 18 mmHg and a cardiac index < 2.2l/min/m(2). The process typically presents with hypotension (systolic blood pressure < 90 mmHg or a decrease in mean arterial pressure > 30 mmHg) and absent or reduced diuresis (< 0.5 ml/kg/h). The most common cause is left ventricular failure due to acute myocardial infarction. Treatment consists of general measures to reverse acidosis and hypoxemia, as well as the use of vasopressors and inotropic drugs. Early coronary revascularization has been demonstrated to improve survival in shock associated with ischaemic heart disease. PMID:24930078

    OBJECTIVE To assess the quality of care of acute myocardial infarction (AMI) in a rural health region. DESIGN Clinical audit employing multiple explicit criteria of care elements for emergency department and in-hospital AMI management. The audit was conducted using retrospective chart review. SETTING Twelve acute care health centres and hospitals in the East Central Health Region, a rural health region in Alberta, where medical and surgical services are provided almost entirely by family physicians. PARTICIPANTS Hospital inpatients with a confirmed discharge diagnosis of AMI (ICD-9-CM codes 410.xx) during the period April 1, 2001, to March 31, 2002, were included (177 confirmed cases). MAIN OUTCOME MEASURES Quality of AMI care was assessed using guidelines from the American College of Cardiology and the American Heart Association and the Canadian Cardiovascular Outcomes Research Team and Canadian Cardiovascular Society. Quality of care indicators at three stages of patient care were assessed: at initial recognition and AMI management in the emergency department, during in-hospital AMI management, and at preparation for discharge from hospital. RESULTS In the emergency department, the quality of care was high for most procedural and therapeutic audit elements, with the exception of rapid electrocardiography, urinalysis, and provision of nitroglycerin and morphine. Average door-to-needle time for thrombolysis was 102.5 minutes. The quality of in-hospital care was high for most elements, but low for nitroglycerin and angiotensin-converting enzyme (ACE) inhibitors, daily electrocardiography, and counseling regarding smoking cessation and diet. Few patients received counseling for lifestyle changes at hospital discharge. Male and younger patients were treated more aggressively than female and older patients. Sites that used care protocols achieved better results in initial AMI management than sites that did not. Stress testing was not readily available in the rural

    The files of patients with acute cholecystitis from two large university hospitals from the years 1978-1985 were employed to find the cases with acute gallbladder perforation for this study. Only those patients (n = 9) were selected for the analysis of sonographic signs of acute gallbladder perforation who had less than 48 hours of symptoms before sonography, and were operated upon within 24 hours of the sonography. Patients (n = 10) with non-complicated acute cholecystitis and identical in regard to the duration of the symptoms and the timing of the sonography and the operation formed a control group. The sonographic findings in patients with gallbladder perforation were pericholecystic fluid collections, free peritoneal fluid, disappearance of the gallbladder wall echoes, focal highly echogenic areas with acoustic shadows in the gallbladder, and an inhomogeneous, generally echo-poor gallbladder wall.

    Ascites is the most common complication of cirrhosis. Ascites develops as a consequence of an abnormal splanchnic vasodilation with reduction of effecting circulating volume and activation of endogenous vasoconstrictors system causing salt and water retention. Patients with ascites have a high risk to develop further complications of cirrhosis such as hyponatremia, spontaneous bacterial peritonitis and acute kidney injury resulting in a poor survival. In recent years, new studies helped a better understanding of the pathophysiology of ascites and acute kidney injury in cirrhosis. Furthermore, new diagnostic criteria have been proposed for acute kidney injury and hepatorenal syndrome and a new algorithm for their management has been recommended with the aim of an early diagnosis and treatment. Herein we will review the current knowledge on the pathophysiology, diagnosis and treatment of ascites and acute kidney injury in patients with cirrhosis and we will identify the unmet needs that should be clarified in the next years.

    Acute gastrointestinal bleeding is a common major emergency (Internal medical or gastroenterological or medical), approximately 85 % of which occur in the upper GI tract. It is estimated that about a half of upper GI bleeds are caused by peptic ulcers. Upper GI bleeds are associated with more severe bleeding and poorer outcomes when compared to middle or lower GI bleeds. Prognostic determinants include bleeding intensity, patient age, comorbid conditions and the concomitant use of anticoagulants. A focused medical history can offer insight into the bleeding intensity, location and potential cause (along with early risk stratification). Initial measures should focus on rapid assessment and resuscitation of unstable patients. The oesophagogastroduodenoscopy (OGD) is the gold standard method for localizing the source of bleeding and for interventional therapy. Bleeding as a result of peptic ulcers is treated endoscopically with mechanical and / or thermal techniques in combination with proton pump inhibitor (PPI) therapy. When variceal bleeding is suspected, pre-interventional use of vasopressin analogues and antibiotic therapies are recommended. Endoscopically, the first line treatment of esophageal varices is endoscopic ligature therapy, whereas that for gastric varices is the use of Histoacryl injection sclerotherapy. When persistent and continued massive hemorrhage occurs in a patient with known or suspected aortic disease the possibility of an aorto-enteric fistula must be considered. PMID:27078246

    Acute myeloid leukaemia (AML) is a disorder characterized by a clonal proliferation derived from primitive haematopoietic stem cells or progenitor cells. Abnormal differentiation of myeloid cells results in a high level of immature malignant cells and fewer differentiated red blood cells, platelets and white blood cells. The disease occurs at all ages, but predominantly occurs in older people (>60 years of age). AML typically presents with a rapid onset of symptoms that are attributable to bone marrow failure and may be fatal within weeks or months when left untreated. The genomic landscape of AML has been determined and genetic instability is infrequent with a relatively small number of driver mutations. Mutations in genes involved in epigenetic regulation are common and are early events in leukaemogenesis. The subclassification of AML has been dependent on the morphology and cytogenetics of blood and bone marrow cells, but specific mutational analysis is now being incorporated. Improvements in treatment in younger patients over the past 35 years has largely been due to dose escalation and better supportive care. Allogeneic haematopoietic stem cell transplantation may be used to consolidate remission in those patients who are deemed to be at high risk of relapse. A plethora of new agents - including those targeted at specific biochemical pathways and immunotherapeutic approaches - are now in trial based on improved understanding of disease pathophysiology. These advances provide good grounds for optimism, although mortality remains high especially in older patients. PMID:27159408

    Acute respiratory distress syndrome (ARDS) is a serious inflammatory disorder with high mortality. Its main pathologic mechanism seems to result from increased alveolar permeability. Its definition has also changed since first being described according to the Berlin definition, which now classifies ARDS on a severity scale based on PaO2 (partial pressure of oxygen, arterial)/FIO2 (fraction of inspired oxygen) ratio. The cornerstone of therapy was found to be a low tidal volume strategy featuring volumes of 6 to 8 mL per kg of ideal body weight that has been shown to have decreased mortality as proven by the ARDSnet trials. There are other areas of treatment right now that include extracorporeal membrane oxygenation, as well for severe refractory hypoxemia. Other methods that include prone positioning for ventilation have also shown improvements in oxygenation. Positive end-expiratory pressure with lung recruitment maneuvers has also been found to be helpful. Other therapies that include vasodilators and neuromuscular agents are still being explored and need further studies to define their role in ARDS. PMID:26919679

    Acute kidney injury is a frequent and serious complication in hospitalized patients. Mortality rates have not substantially been decreased during the last 20 years. In most patients AKI results from transient renal hypoperfusion or ischemia. The consequences include tubular cell dysfunction/damage, inflammation of the organ, and post-ischemic microvasculopathy. The two latter events perpetuate kidney damage in AKI. Clinical manifestations result from diminished excretion of water, electrolytes, and endogenous / exogenous waste products. Patients are endangered by cardiovascular complications such as hypertension, heart failure, and arrhythmia. In addition, the whole organism may be affected by systemic toxification (uremia). The diagnostic approach in AKI involves several steps with renal biopsy inevitable in some patients. The current therapy focuses on preventing further kidney damage and on treatment of complications. Different pharmacological strategies have failed to significantly improve prognosis in AKI. If dialysis treatment becomes mandatory, intermittent and continuous renal replacement therapies are equally effective. Thus, new therapies are urgently needed in order to reduce short- and long-term outcome in AKI. In this respect, stem cell-based regimens may offer promising perspectives. PMID:25618438

    A 34-year-old woman with a diagnosis of hemophagocytic lymphohistocytosis (HLH) received a double umbilical cord blood transplantation following a myeloablative chemotherapy preparative regimen with busulfan and cyclophosphamide. HLH is a rare, potentially fatal hematologic disorder characterized by the overactivation of histocytes and T lymphocytes, leading to organ infiltration and acute illness. On day 25 post-transplantation, the patient required a platelet transfusion for a platelet count of 6,000 per ml (normal range = 150,000-450,000 per ml). The patient's blood type prior to the cord blood transplantation was B positive and, although both umbilical cord blood donors were O positive, the patient was still B positive per blood bank testing on that day. Although the recipient of an allogenic stem cell transplantation will eventually become the blood type of the donor, the time for this process to occur varies for each person. That process must be monitored by the blood bank for the purpose of cross-matching blood products to decrease hemolysis as much as possible. The patient was premedicated with the facility's standard for platelet transfusions: acetaminophen 650 mg and diphenhydramine 25 mg about 30 minutes prior to the platelet transfusion. PMID:24161631

On arrival the patient looked peri-arrest. His O2 saturations were 84% on 15 L of oxygen. He had gasping breathing with a completely silent chest and the GCS was 6/15 (E=1, V=1, M=4). The blood gas revealed type-2 respiratory failure. The chest X-ray was unremarkable and ECG was not indicative for cardiac catheterisation lab activation. Bedside shock scan was done which showed global hypokinesia of the left ventricle. In spite of unconvincing ECG and chest X-ray, an acute cardiac event was diagnosed in view of an abnormal bedside echo. The patient was transferred to the cardiac catheterisation lab for urgent percutaneous coronary intervention which revealed critical stenosis of the left main stem coronary artery, which was successfully stented. The patient had a good recovery from the life-threatening event. PMID:24913081

    Acute diarrhea (AD) is the most frequent gastroenterological disorder, and the main cause of dehydration in childhood. It is manifested by a sudden occurrence of three or more watery or loose stools per day lasting for seven to 10 days, 14 days at most. It mainly occurs in children until five years of age and particularly in neonates in the second half-year and children until the age of three years. Its primary causes are gastrointestinal infections, viral and bacterial, and more rarely alimentary intoxications and other factors. As dehydration and negative nutritive balance are the main complications of AD, it is clear that the compensation of lost body fluids and adequate diet form the basis of the child's treatment. Other therapeutic measures, except antipyretics in high febrility, antiparasitic drugs for intestinal lambliasis, anti-amebiasis and probiotics are rarely necessary. This primarily regards uncritical use of antibiotics and intestinal antiseptics in the therapy of bacterial diarrhea.The use of antiemetics, antidiarrhetics and spasmolytics is unnecessary and potentially risky, so that it is not recommended for children with AD.

    Introduction Anterior uveitis is rare, with an annual incidence of 12/100,000 population, although it is more common in Finland (annual incidence of 23/100,000), probably because of genetic factors, such as high frequency of HLA–B27 in the population. It is often self-limiting, but can, in some cases, lead to complications such as posterior synechiae, cataract, glaucoma, and chronic uveitis. Methods and outcomes We conducted a systematic review and aimed to answer the following clinical question: What are the effects of anti-inflammatory eye drops on acute anterior uveitis? We searched: Medline, Embase, The Cochrane Library and other important databases up to November 2009 (Clinical Evidence reviews are updated periodically, please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). Results We found six systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. Conclusions In this systematic review we present information relating to the effectiveness and safety of the following interventions: corticosteroids, mydriatics, and non-steroidal anti-inflammatory drug eye drops.

    Idiopathic demyelinating optic neuritis (ON) most commonly presents as acute unilateral vision loss and eye pain and is frequently associated with multiple sclerosis. Although emphasis is often placed on the good recovery of high-contrast visual acuity, persistent deficits are frequently observed in other aspects of vision, including contrast sensitivity, visual field testing, color vision, motion perception, and vision-related quality of life. Persistent and profound structural and functional changes are often revealed by imaging and electrophysiologic techniques, including optical coherence tomography, visual-evoked potentials, and nonconventional MRI. These abnormalities can impair patients' abilities to perform daily activities (e.g., driving, working) so they have important implications for patients' quality of life. In this article, we review the sequelae from ON, including clinical, structural, and functional changes and their interrelationships. The unmet needs in each of these areas are considered and the progress made toward meeting those needs is examined. Finally, we provide an overview of past and present investigational approaches for disease modification in ON. PMID:26236761

We describe a patient who developed moderately severe acute pancreatitis as an untoward consequence after being initiated on this drug. To the best of our knowledge, this is the first reported case of canagliflozin-associated acute pancreatitis in clinical literature. PMID:25187092

    Over a two-month period 30 patients were admitted to hospital following stings of the scorpion of Trinidad, the Tityus trinitatis. In 24 cases acute pancreatitis developed soon after the sting, but in nine of these no abdominal pain occurred. All the patients made an uneventful recovery. Although such complications have been reported no pseudocyst formations or acute haemorrhagic pancreatitis occurred in this series. PMID:5443968

    Amebiasis presenting as acute appendicitis is extremely rare. The case of a 38-year-old Hispanic man who presented to the hospital with symptoms and signs suggestive of acute appendicitis is reported. He underwent laparoscopic appendectomy and the pathologic examination of the appendix revealed multiple trophozoites of Entamoeba histolytica. The patient was treated postoperatively with metronidazole for amebiasis, and follow-up stool studies showed no sign of residual infection. The patient has remained asymptomatic. PMID:17984748

    Abstract Acute acquired concomitant esotropia (AACE) is a rare, distinct subtype of esotropia. The purpose of this retrospective study was to describe the clinical characteristics and discuss the classification and etiology of AACE. Charts from 47 patients with AACE referred to our institute between October 2010 and November 2014 were reviewed. All participants underwent a complete medical history, ophthalmologic and orthoptic examinations, and brain and orbital imaging. Mean age at onset was 26.6 ± 12.2 years. Of the 18 cases with deviations ≤ 20 PD, 16 presented with diplopia at distance and fusion at near vision at the onset of deviation; differences between distance and near deviations were < 8 PD; all cases except one were treated with prism and diplopia resolved. Of the 29 cases with deviations > 20 PD, 5 were mild hypermetropic with age at onset between 5 and 19 years, 16 were myopic, and 8 were emmetropic with age at onset > 12 years; 24 were surgically treated and 5 cases remained under observation; all 24 cases achieved normal retinal correspondence or fusion or stereopsis on postoperative day 1 in synoptophore; in 23 cases diplopia or visual confusion resolved postoperatively. Of the 47 cases, brain and orbital imaging in 2 cases revealed a tumor in the cerebellopontine angle and 1 case involved spinocerebellar ataxia as revealed by genetic testing. AACE in this study was characterized by a sudden onset of concomitant nonaccommodative esotropia with diplopia or visual confusion at 5 years of age or older and the potential for normal binocular vision. We suggest that AACE can be divided into 2 subgroups consisting of patients with relatively small versus large angle deviations. Coexisting or underlying neurological diseases were infrequent in AACE. PMID:26705210

    Prolonged breathing of very high FIO2 (FIO2 ≥ 0.9) uniformly causes severe hyperoxic acute lung injury (HALI) and, without a reduction of FIO2, is usually fatal. The severity of HALI is directly proportional to PO2 (particularly above 450 mm Hg, or an FIO2 of 0.6) and exposure duration. Hyperoxia produces extraordinary amounts of reactive O2 species that overwhelms natural antioxidant defenses and destroys cellular structures through several pathways. Genetic predisposition has been shown to play an important role in HALI among animals, and some genetics-based epidemiologic research suggests that this may be true for humans as well. Clinically, the risk of HALI likely occurs when FIO2exceeds 0.7, and may become problematic when FIO2 exceeds 0.8 for an extended period of time. Both high-stretch mechanical ventilation and hyperoxia potentiate lung injury and may promote pulmonary infection. During the 1960s, confusion regarding the incidence and relevance of HALI largely reflected such issues as the primitive control of FIO2, the absence of PEEP, and the fact that at the time both ALI and ventilator-induced lung injury were unknown. The advent of PEEP and precise control over FIO2, as well as lung-protective ventilation, and other adjunctive therapies for severe hypoxemia, has greatly reduced the risk of HALI for the vast majority of patients requiring mechanical ventilation in the 21st century. However, a subset of patients with very severe ARDS requiring hyperoxic therapy is at substantial risk for developing HALI, therefore justifying the use of such adjunctive therapies. PMID:23271823

    2001-01-01

    Through the hard work of a large number of investigators, the biology of acute myeloid leukemia (AML) is becoming increasingly well understood, and as a consequence, new therapeutic targets have been identified and new model systems have been developed for testing novel therapies. How these new therapies can be most effectively studied in the clinic and whether they will ultimately improve cure rates are questions of enormous importance. In this article, Dr. Jacob Rowe presents a summary of the current state-of-the-art therapy for adult AML. His contribution emphasizes the fact that AML is not a single disease, but a number of related diseases each distinguished by unique cytogenetic markers which in turn help determine the most appropriate treatment. Dr. Jerald Radich continues on this theme, emphasizing how these cytogenetic abnormalities, as well as other mutations, give rise to abnormal signal transduction and how these abnormal pathways may represent ideal targets for the development of new therapeutics. A third contribution by Dr. Frederick Appelbaum describes how AML might be made the target of immunologic attack. Specifically, strategies using antibody-based or cell-based immunotherapies are described including the use of unmodified antibodies, drug conjugates, radioimmunoconjugates, non-ablative allogeneic transplantation, T cell adoptive immunotherapy and AML vaccines. Finally, Dr. John Dick provides a review of the development of the NOD/SCID mouse model of human AML emphasizing both what it has taught us about the biology of the disease as well as how it can be used to test new therapies. Taken together, these reviews are meant to help us understand more about where we are in the treatment of AML, where we can go and how we might get there. PMID:11722979

    There are many options for acute migraine attack treatment, but none is ideal for all patients. This study aims to review current medical office-based acute migraine therapy in adults and provides readers with an organized approach to this important facet of migraine treatment. A general literature review includes a review of several recent published guidelines. Acetaminophen, 4 nonsteroidal anti-inflammatory drugs (NSAIDs) (ibuprofen, acetylsalicylic acid [ASA], naproxen sodium, and diclofenac potassium), and 7 triptans (almotriptan, eletriptan, frovatriptan, naratriptan, rizatriptan, sumatriptan, and zolmitriptan) have good evidence for efficacy and form the core of acute migraine treatment. NSAID-triptan combinations, dihydroergotamine, non-opioid combination analgesics (acetaminophen, ASA, and caffeine), and several anti-emetics (metoclopramide, domperidone, and prochlorperazine) are additional evidence-based options. Opioid containing combination analgesics may be helpful in specific patients, but should not be used routinely. Clinical features to be considered when choosing an acute migraine medication include usual headache intensity, usual rapidity of pain intensity increase, nausea, vomiting, degree of disability, patient response to previously used medications, history of headache recurrence with previous attacks, and the presence of contraindications to specific acute medications. Available acute medications can be organized into 4 treatment strategies, including a strategy for attacks of mild to moderate severity (strategy one: acetaminophen and/or NSAIDs), a triptan strategy for patients with severe attacks and for attacks not responding to strategy one, a refractory attack strategy, and a strategy for patients with contraindications to vasoconstricting drugs. Acute treatment of migraine attacks during pregnancy, lactation, and for patients with chronic migraine is also discussed. In chronic migraine, it is particularly important that medication

    Acute or subacute chemical-induced lung injury is rarely compound specific and is most often caused by an accidental occupational, domestic or environmental exposure to an inhaled chemical agent. The industrial disaster that happened in Bhopal in 1984, accidental poisoning with chlorine and petroleum hydrocarbons and also vesicant gases used during conflicts, are specific examples. Rarely, a chemical agent can cause lung damage by being ingested and reaching the lung through the systemic circulation (for example accidental or deliberate paraquat ingestion). Household accidents should not be underestimated. An important cause of household accidents is chlorine inhalation resulting from mixing bleach with acids such as the scale removers used to clean toilets. Chemical agents can provoke direct and/or indirect damage to the respiratory tract. The acute or subacute clinical manifestations resulting from inhalation of chemical agents are very varied and include inhalation fevers, acute non-cardiogenic pulmonary oedema, adult respiratory distress syndrome, reactive airways dysfunction syndrome and acute or subacute pneumonitis. The site and the severity of chemical-induced respiratory damage caused by inhaled chemical agents depend mainly on the nature and the amount of the agent inhaled. The immediate and long-term prognosis and possible sequelae are also variable. This review excludes infectious or immunologically induced acute respiratory diseases. PMID:19953031

    This is a report of nine patients who experienced sudden, severe, unilateral central vision loss following a flulike illness. Each patient had an exudative detachment of the macula. All patients experienced a spontaneous resolution of the acute macular manifestations with near-complete recovery of vision. A characteristic "bull's-eye" appearance in the macula persisted. The acute manifestations of the disorder did not recur in any of the patients during the period of follow-up. The constellation of findings was suggestive of an inflammatory disease of the retinal pigment epithelium, but a specific causative agent could not be identified. The acute clinical and angiographic features, the natural course, and the residual pigment epithelial derangement were not consistent with any previously described disorder. PMID:22451959

    2016-08-01

    Autophagy is an evolutionarily ancient mechanism that ensures the lysosomal degradation of old, supernumerary or ectopic cytoplasmic entities. Most eukaryotic cells, including neurons, rely on proficient autophagic responses for the maintenance of homeostasis in response to stress. Accordingly, autophagy mediates neuroprotective effects following some forms of acute brain damage, including methamphetamine intoxication, spinal cord injury and subarachnoid haemorrhage. In some other circumstances, however, the autophagic machinery precipitates a peculiar form of cell death (known as autosis) that contributes to the aetiology of other types of acute brain damage, such as neonatal asphyxia. Here, we dissect the context-specific impact of autophagy on non-infectious acute brain injury, emphasizing the possible therapeutic application of pharmacological activators and inhibitors of this catabolic process for neuroprotection.

    Acute hepatitis is a very rare, but potentially fatal, adverse effect of intravenous amiodarone. We present a case of an 88-year-old man with history of ischemic dilated cardiomyopathy and severely depressed left ventricular function that was admitted to our coronary care unit with diagnosis of decompensated heart failure and non-sustained ventricular tachycardia. A few hours after the beginning of intravenous amiodarone he developed an acute hepatitis. There was a completely recovery within the next days after amiodarone withdrawn and other causes of acute hepatitis have been ruled out. This case highlights the need for close monitoring of hepatic function during amiodarone infusion in order to identify any potential hepatotoxicity and prevent a fatal outcome. Oral amiodarone is, apparently, a safe option in these patients. PMID:26488027

    The acute respiratory distress syndrome (ARDS) is a major cause of acute respiratory failure. Its development leads to high rates of mortality, as well as short- and long-term complications, such as physical and cognitive impairment. Therefore, early recognition of this syndrome and application of demonstrated therapeutic interventions are essential to change the natural course of this devastating entity. In this review article, we describe updated concepts in ARDS. Specifically, we discuss the new definition of ARDS, its risk factors and pathophysiology, and current evidence regarding ventilation management, adjunctive therapies, and intervention required in refractory hypoxemia.

    Acute kidney injury (AKI) is a frequent complication of end-stage liver disease, especially in those with acute-on-chronic liver failure, occurring in up to 50% of hospitalized patients with cirrhosis. There is no specific blood or urine biomarker that can reliably identify the cause of AKI in cirrhotic patients. This review examines studies used to assess renal dysfunction in cirrhotic patients including new diagnostic criteria and potential novel biomarkers. Although biomarker development to differentiate the cause of AKI in cirrhosis has promise, the utility of biomarkers to determine irreversible renal dysfunction with liver transplant remains lacking, warranting further investigation.

    Acute scrotum is a urologic condition defined by scrotal pain, swelling, and redness of acute onset. Prompt diagnosis and treatment are necessary to preserve testicular viability. The history and clinical symptoms reported are key to diagnosis and proper treatment, but are not always readily obtained in children, in whom common causes of acute scrotum include testicular torsion, torsion of the appendix testis, and epididymitis. These acute conditions have different causal pathology that mandate specific treatment, hence the importance of early and accurate diagnosis.

    2010-04-01

    Optimum acute treatment of migraine requires prevention of headache as a top priority. Recognition of the multitude of migraine presentations, the frequency of total headache attacks, and number of days of headache disability are critical. Successful treatment requires excellent patient-clinician communication enhancing confidence and mutual trust based on patient needs and preferences. Optimum management of acute migraine nearly always requires pharmacologic treatment for rapid resolution. Migraine-specific triptans, dihydroergotamine, and several antiinflammatories have substantial empirical clinical efficacy. Older nonspecific drugs, particularly butalbital and opioids, contribute to medication overuse headache and are to be avoided. Clinicians should utilize evidence-based acute migraine-specific therapy stressing the imperative acute treatment goal of early intervention, but not too often with the correct drug, formulation, and dose. This therapy needs to provide cost-effective fast results, meaningful to the patient while minimizing the need for additional drugs. Migraine-ACT evaluates 2-hour pain freedom with return to normal function, comfort with treatment, and consistency of response. Employ a thoroughly educated patient, formulary, testimonials, stratification, and rational cotherapy against the race to central sensitization for optimum outcomes. PMID:20352584

    2014-01-01

    While conservative management such as fluid, bowel rest, and antibiotics is the mainstay of current acute pancreatitis management, there is a lot of promise in pharmacologic therapies that target various aspects of the pathogenesis of pancreatitis. Extensive review of preclinical studies, which include assessment of therapies such as anti-secretory agents, protease inhibitors, anti-inflammatory agents, and anti-oxidants are discussed. Many of these studies have shown therapeutic benefit and improved survival in experimental models. Based on available preclinical studies, we discuss potential novel targeted pharmacologic approaches that may offer promise in the treatment of acute pancreatitis. To date a variety of clinical studies have assessed the translational potential of animal model effective experimental therapies and have shown either failure or mixed results in human studies. Despite these discouraging clinical studies, there is a great clinical need and there exist several preclinical effective therapies that await investigation in patients. Better understanding of acute pancreatitis pathophysiology and lessons learned from past clinical studies are likely to offer a great foundation upon which to expand future therapies in acute pancreatitis.

    Psychotic disorders with acute onset, a dramatic and polymorphous symptomatology and rapid resolution have been described in different countries and by different psychiatric schools. They have been called cycloid psychosis, bouffée délirante, psychogenic psychosis or good prognosis schizophrenia. ICD-10 has given an operational definition under the name "acute and transient psychotic disorders" (F23). Their nosological status is unclear. The Halle-Study of acute and transient psychotic disorders (ATPD) has investigated in a prospective manner clinical, para-clinical features and course of illness in 42 patients with ATPD and matched controls with positive schizophrenia, bipolar schizoaffective disorders as well as mentally healthy patients with acute surgical conditions. First results of our study show that ATPD amount to 4% of psychotic in-patients, prefer female sex, show short prodromi, marked affective disturbances within the episode and much better outcome as schizophrenic psychoses according to psychopathological, social, psychological and biographical criteria. Though ATPD may still be an inhomogeneous group, their clinical delineation from schizophrenia seems justified. PMID:10907609

    2015-01-01

    Acute interstitial nephritis (AIN) is characterized by inflammation of the renal interstitium and usually occurs in a temporal relationship with the medication. We present a case of an Asian male who had nephrotic range proteinuria and presented with acute kidney injury. The patient reported an acute change in physical appearance and symptomatology after the ingestion of a single dose of sildenafil. Renal biopsy was notable for minimal change disease (MCD) with acute and chronic interstitial nephritis. Renal replacement and glucocorticoid therapy were initiated. Renal recovery within six weeks permitted discontinuation of dialysis. AIN superimposed on MCD is a known association of NSAID induced nephropathy. The temporal association and the absence of any new drugs suggest that the AIN was most likely due to the sildenafil. NSAIDs are less likely to have caused the AIN given their remote use. The ease of steroid responsiveness would also suggest another cause as NSAID induced AIN is often steroid resistant. The MCD was most likely idiopathic given the lack of temporal association with a secondary cause. As the number of sildenafil prescriptions increases, more cases of AIN may be identified and physician awareness for this potential drug disease association is necessary. PMID:26491581

    2015-01-01

    Acute pancreatitis is an inflammatory process of the pancreatic gland that eventually may lead to a severe systemic inflammatory response. A key event in pancreatic damage is the intracellular activation of NF-κB and zymogens, involving also calcium, cathepsins, pH disorders, autophagy, and cell death, particularly necrosis. This review focuses on the new role of redox signaling in acute pancreatitis. Oxidative stress and redox status are involved in the onset of acute pancreatitis and also in the development of the systemic inflammatory response, being glutathione depletion, xanthine oxidase activation, and thiol oxidation in proteins critical features of the disease in the pancreas. On the other hand, the release of extracellular hemoglobin into the circulation from the ascitic fluid in severe necrotizing pancreatitis enhances lipid peroxidation in plasma and the inflammatory infiltrate into the lung and up-regulates the HIF–VEGF pathway, contributing to the systemic inflammatory response. Therefore, redox signaling and oxidative stress contribute to the local and systemic inflammatory response during acute pancreatitis. PMID:25778551

    Nephroscintigraphy using a 67Ga-citrate complex and 99mTc-pyrophosphate was performed in 88 patients with acute pyelonephritis. Nuclide hyperfixation was revealed in 97.8% of the cases. Three groups of patients were singled out on the basis of the intensity of incorporation and nature of the distribution of the radiopharmaceuticals (RP) in the kidneys. In the 1st group the RP incorporation was insignificant but higher than normal values; the RP distribution in the affected kidney was diffuse-inhomogenous. These changes were considered to be typical of acute serous pyelonephritis. In the 2nd and 3rd groups a sharp rise of the RP accumulation was noted, being typical of acute purulent pyelonephritis. One could distinguish between diffuse and focal lesions by the picture of the RP distribution in the renal parenchyma. Diuresis stimulation made it possible to differentiate an actual nuclide fixation during inflammation from nuclide mechanical retention as a result of urine outflow disorder. According to the authors, both radiopharmaceuticals could be applied for the diagnosis of acute pyelonephritis as well as for differential diagnosis of various forms of the disease. PMID:3001474

  1. Acute treatment of atrial fibrillation.

    Atrial fibrillation (AFib) is a common clinical entity, responsible for significant morbidity and mortality, but it also accounts for a large percentage of healthcare dollar expenditures. Efforts to treat this arrhythmia in the past have focused on subacute antithrombotic therapy and eventually use of antiarrhythmic drugs for maintenance of sinus rhythm. However, there has been a growing interest in the concept of acute electrical and pharmacologic conversion. This treatment strategy has a number of benefits, including immediate alleviation of patient symptoms, avoidance of antithrombotic therapy, and prevention of electrophysiologic remodeling, which is thought to contribute to the perpetuation of the arrhythmia. There is also increasing evidence that this is a cost-effective strategy in that it may obviate admission to the hospital and the cost of long-term therapy. This article represents a summary of the treatments that may be used acutely to control the ventricular response to AFib, prevent thromboembolic events, and provide for acute conversion either pharmacologically or electrically. It includes information on modalities that are currently available and those that are under active development. We anticipate that an active, acute treatment approach to AFib and atrial flutter will become the therapeutic norm in the next few years, especially as the benefits of these interventions are demonstrated in clinical trials.

    Summary Background Identifying patients at risk for acute respiratory distress syndrome (ARDS) before their admission to intensive care is crucial to prevention and treatment. The objective of this study is to determine the performance of an automated algorithm for identifying selected ARDS predisposing conditions at the time of hospital admission. Methods This secondary analysis of a prospective cohort study included 3,005 patients admitted to hospital between January 1 and December 31, 2010. The automated algorithm for five ARDS predisposing conditions (sepsis, pneumonia, aspiration, acute pancreatitis, and shock) was developed through a series of queries applied to institutional electronic medical record databases. The automated algorithm was derived and refined in a derivation cohort of 1,562 patients and subsequently validated in an independent cohort of 1,443 patients. The sensitivity, specificity, and positive and negative predictive values of an automated algorithm to identify ARDS risk factors were compared with another two independent data extraction strategies, including manual data extraction and ICD-9 code search. The reference standard was defined as the agreement between the ICD-9 code, automated and manual data extraction. Results Compared to the reference standard, the automated algorithm had higher sensitivity than manual data extraction for identifying a case of sepsis (95% vs. 56%), aspiration (63% vs. 42%), acute pancreatitis (100% vs. 70%), pneumonia (93% vs. 62%) and shock (77% vs. 41%) with similar specificity except for sepsis and pneumonia (90% vs. 98% for sepsis and 95% vs. 99% for pneumonia). The PPV for identifying these five acute conditions using the automated algorithm ranged from 65% for pneumonia to 91 % for acute pancreatitis, whereas the NPV for the automated algorithm ranged from 99% to 100%. Conclusion A rule-based electronic data extraction can reliably and accurately identify patients at risk of ARDS at the time of hospital

    Neuromuscular diseases can affect all respiratory muscles, leading to acute respiratory failure, which is the most common cause of morbidity and mortality in those patients. Two situations must be distinguished. 1) Acute respiratory failure as part of a neuromuscular disorder of acute onset and possibly reversible (Guillain-Barre syndrome, myasthenic crisis...). 2) Acute respiratory failure occurring in a patient with an already advanced neuromuscular disease (amyotrophic lateral sclerosis, Duchenne muscular dystrophy...). This article describes the neuromuscular acute respiratory failure in these different aspects, discusses its initial management in the emergency department and identifies the parameters that have to be monitored.

    Acute kidney injury (AKI) is increasingly being seen in patients with acute coronary syndromes (ACSs). This condition has a complex pathogenesis, an incidence that can reach 30% and it is associated with higher short-term and long-term morbidity and mortality. Nevertheless, AKI is still characterised by lack of a single accepted definition, unclear pathophysiology understanding and insensitive diagnostic tools that make its detection difficult, particularly in the setting of ACS. Recent data suggested that patients with AKI during ACS, even those in whom renal function seems to fully recover, face an increased, persisting risk of future AKI and may develop chronic kidney disease. Thus, in these patients, nephrology follow-up, after hospital discharge, and secondary preventive measures should possibly be implemented. In this review, we aim at providing a framework of knowledge to increase cardiologists' awareness of AKI, with the goal of improving the outcome of patients with ACS. PMID:26243789

    Rhabdomyolysis is a rare complication that emerges in a variety of infectious diseases, such as tsutsugamushi infection. In this study, we report a 71-year-old female patient with tsutsugamushi infection who exhibiting rhabdomyolysis and acute renal failure. On admission, an eschar, which is characteristic of tsutsugamushi infection, was found on her right flank area. Moreover, her tsutsugamushi antibody titer was 1:40960. The elevated values of serum creatinine phosphokinase (CPK), aldolase, creatinine and dark brown urine secondary to myoglobinuria are consistent with indications of rhabdomyolysis and acute renal failure due to tsutsugamushi infection. Her health improved without any residual effects after treatment with doxycyclin and hydration with normal saline. PMID:14717236

    Acute unilateral vestibulopathy (AUV) is characterized by acute vertigo, nausea, and imbalance without neurological deficits or auditory symptomatology. Here, we explore the effect of glucocorticoid treatment on the degree of canal paresis in patients with AUV, and critically, establish its relationship with dizziness symptom recovery. We recruited consecutive patients who were retrospectively assigned to one of the two groups according to whether they received glucocorticoid treatment (n = 32) or not (n = 44). All patients underwent pure-tone audiometry, bithermal caloric testing, MRI brain imaging, and were asked to complete a dizziness handicap inventory on admission to hospital and just prior to hospital discharge. In the treatment group, the canal paresis at discharge was significantly lower than in the control group (mean ± SD % 38.04 ± 21.57 versus 82.79 ± 21.51, p < 0.001). We also observed a significant reduction in the intensity of nystagmus in patients receiving glucocorticoid treatment compared to the non-treatment group (p = 0.03). DHI test score was significantly lower at discharge in the treatment group (mean ± SD % 23.15 ± 12.40 versus 64.07 ± 12.87, p < 0.001), as was the length of hospital stay (2.18 ± 1.5 days versus 3.6 ± 1.7 days, p = 0.002). Glucocorticoid treatment leads to acute symptomatic improvement, with a reduced hospital stay and reduction in the intensity of acute nystagmus. Our findings suggest that glucocorticoids may accelerate vestibular compensation via a restoration of peripheral vestibular function, and therefore has important clinical implications for the treatment of AUV.

    Urinary tract infection (UTI) may predominantly involve the lower urinary tract, i.e. acute cystitis, or upper urinary tract consisting of the renal pelvis and kidney,, i.e. acute pyelonephritis The incidence of acute pyelonephritis is higher in young women than in men but the incidence in men over 65 is similar to that in older women. Women have up to a 10% risk of recurrent acute pyelonephritis in the year following a first acute episode. The equivalent risk in men is 6%. Acute pyelonephritis may be uncomplicated and resolve without serious sequelae. A minority of episodes may be complicated by acute kidney injury, papillary necrosis, renal or perinephric abscess or the development of emphysematous pyelonephritis. Acute pyelonephritis is generally caused by microorganisms ascending from the urethra via the bladder into the upper urinary tract. Rarely the kidney may be seeded by blood-borne infection. Ecoli is the most common uropathogen causing pyelonephritis accounting for 70-90% of infections. Species of Enterococci, Klebsiella, Pseudomonas, Proteus and Staphylococci are responsible for the remaining infections. There is a rising incidence in the community of UTI with bacteria that produce extended spectrum beta-lactamase (ESBL) enzymes. These ESBL bacteria have developed resistance to antibiotics such as penicillin, cephalosporins and increasingly to quinolones. Risk factors for uncomplicated acute pyelonephritis include recent sexual intercourse, acute cystitis, stress incontinence and diabetes and for complicated acute pyelonephritis include pregnancy, diabetes, anatomical abnormalities of the urinary tract and renal calculi.

    Acute respiratory distress is one of the most common reason for emergency visits in children under 5 y of age. An accurate understanding of the epidemiology of these diseases, identification of risk factors and etiology is critical for successful treatment and prevention of related mortality. The cause of acute respiratory distress varies in etiology, and hence is amenable to different treatment modalities. Depending on the predominant symptoms and signs, a child presenting to the clinician can be divided into six groups, viz., stridor; cough, fever and difficulty in breathing or fast breathing; wheezing; mediastinal shift with severe respiratory distress; slow or irregular breathing in absence of any pulmonary sign; and respiratory distress with cardiac findings. A detailed history followed by a thorough clinical examination and laboratory evaluation assisted by imaging modalities if indicated, helps to establish the exact cause of respiratory distress in the child. Early recognition and prompt institution of appropriate management or referral can significantly improve the outcome of this illness. This article offers clinicians a brief update on the general management guidelines of respiratory distress in pediatric patients. Specific treatment depends on the exact cause, however croup and acute severe asthma have been discussed in this article. PMID:25257964

    The approach of the Joint Meeting on Pesticide Residues to the establishment of the acute reference dose for pesticides is presented and related issues are discussed. Three main points seem relevant when discussing the acute reference dose: (1) what compounds should have an acute reference dose, (2) what toxicological database is required for the establishment of an acute reference dose; (3) what safety factors are to be used. It is concluded that (1) groups of compounds that need an acute reference dose can be identified, whereas general rules for identifying groups not requiring an acute reference dose cannot be easily given; (2) studies from the standard toxicological database can often be used to allocate an acute reference dose and the usefulness of refinements (by requesting specific studies) should be evaluated after intake assessment; general rules on study requirements cannot be easily given; (3) more thought should be given to what safety factors apply in certain circumstances.

    Summary Acute graft-versus-host disease (GVHD) is a leading cause of non-relapse mortality following allogeneic haematopoietic cell transplantation. Attempts to improve treatment response in clinically-established GVHD have not improved overall survival, often due to the increased risk of infectious complications. Alternative approaches to decrease GVHD-related morbidity and mortality have focused on the ability to predict GVHD prior to clinical manifestation in an effort to provide an opportunity to abort GVHD development, and to gain new insights into GVHD pathophysiology. This review outlines the research efforts to date that have identified clinical and laboratory-based factors that are predictive of acute GVHD and describes future directions in developing algorithms that will improve the ability to predict the development of clinically relevant GVHD.

    Exenatide is an incretin mimetic. It was approved by the federal drug authority in 2005 for the treatment of type-2 diabetes. Since it is a relatively new medicine clinicians have limited experience with regards to its side effects and safety profile. We report a 47 year old lady who presented with exenatide associated acute kidney injury. She had type-2 diabetes for 10 years with mild micro albuminuria and normal renal functions. She was also taking a stable dose of metformin, gliclazide, angiotensin converting enzyme inhibitor and diuretic for over a year and there was no history of any recent use of non-steroid anti-inflammatory medications. One week after starting exenatide, she developed severe vomiting, followed by hypotension. She presented with acute renal insufficiency and severe lactic acidosis and had to be dialyzed on emergency basis. To our knowledge this is probably the first case reported in the local United Arab Emirate (U.A.E) population. PMID:25672206

    Syringohydromyelia is a frequent finding in cases of tethered cord syndrome. The classical teaching is that the development and progression of a syrinx is a chronic process. We present a case report of an acute onset syringomyelia in an infant, who underwent an excision of a lumbosacral transitional lipoma and detethering of the cord. Immediately after recovery, the infant was found to have flaccid paraplegia. An emergency magnetic resonance imaging revealed a large acute onset syringomyelia for which he underwent an emergency midline myelotomy and release of fluid from the syrinx. Though the eventual recovery was good, this made us re-visit our understanding of the concept of syringohydromyelia. The case details and a plausible hypothesis for the rapid development of the syrinx are presented. PMID:26557165

    Over 2.5 million accidental and intentional drug-related poisonings are reported annually in the United States. Early diagnosis and management of patients who present with acute intoxication can significantly reduce both morbidity and mortality. The initial evaluation of patients with suspected or proven intoxications should focus on hemodynamic stability, mental status, and respiratory function. However, early recognition of toxic ingestion is paramount to implementing life-saving treatments. Important historical clues are often found in a social history that considers intravenous drug use, alcohol use, and any access or exposure to illicit substances. A patient's medication list should also be scrutinized for psychoactive or sedative medications, such as tricyclic antidepressants or opioids. In this article we present case-based discussions of the specific diagnosis and management of 5 commonly occurring acute intoxication syndromes. PMID:20877175

    A significant amount of clinicians' time is spent managing patients with complications arising from the use of sympatheticomimetic drugs such as cocaine and ecstasy, or MDMA. This article examines one of these complications, namely acute hyponatraemia, which can have life-threatening neurological consequences. Although there are few signs or symptoms of this condition, emergency clinicians should be able to recognise when it may have occurred, and should have a basic understanding of the role of sodium in autoregulation of cellular function, the different fluid compartments in the human body and the pathology of cerebral oedema. The article describes the importance of early recognition and swift treatment of acute hyponatraemia, as well as the methods for calculating fluid replacement to optimise chances of full recovery.

Management is primarily supportive, with care taken to anticipate the known complications of hepatic failure. Few "curative" therapies are known, although attempts at stimulating hepatic regeneration may be helpful. Images FIG. 1 FIG. 3 FIG. 4 PMID:6433587

    We present a case of acute suprachoroidal hemorrhage that developed during routine phacoemulsification in an 85-year-old patient after uneventful administration of periocular anesthesia. Pre-existing risk factors included advanced age, glaucoma, myopia, and hypertension. The scleral tunnel prevented major expulsion of intraocular contents; however, raised intraocular pressure prevented intraocular lens implantation. The rarity of this condition raises questions regarding the further management and precautions related to it. PMID:10889443

    Neuroimaging, particularly MR imaging, plays a major role for the diagnosis of many acute toxic encephalopathies. Toxic disorders are related to drugs (immunosuppressive agents, chemotherapeutic agents, anti-epileptic drugs, heroin...), to metals (lead, manganese, mercury...), and to industrial and environmental chemicals (solvent, carbon monoxide...). MR imaging with diffusion and perfusion imaging provides information regarding brain lesions induced by the toxic agents (vasogenic edema, cytotoxic edema, infarction, hemorrhage, demyelination...).

    Four cases, including three adults and one child, suffering from acute poisoning with Tricholoma equestre were described. The patients had eaten from 100 to 400 grams of the mushroom within a few consecutive meals. After consuming about 1000 grams of Tricholoma equestre for 3-4 days, the subjects developed fatigue, muscle weakness, myalgia, and in two cases acute respiratory failure with the need of respiratorotherapy. Maximal serum CK was 48136 U/L in the adults and 306 U/L in children. Maximal serum levels of AST and ALT were 802 U/L and 446 U/L in adults and 39 U/L, and 56 U/L in a child. All routine biochemical tests were within normal range. No other causes of rhabdomyolysis such as parasitic or viral infections, immune diseases, trauma or exposure to medications were found. Patient, aged 72 yrs., who developed acute respiratory failure, died in the second day of hospitalization. In other patients all the above mentioned symptoms and biochemical abnormalities disappeared from 2 to 3 weeks of hospitalization. Physicians should be aware of the possibility of appearance of rhabdo-myolysis after repeated consumption of large quantities of Tricholoma equestre. PMID:19788144

  15. Management of Acute Variceal Bleeding

    PubMed Central

    2014-01-01

    Acute variceal bleeding could be a fatal complication in patients with liver cirrhosis. In patients with decompensated liver cirrhosis accompanied by ascites or hepatic encephalopathy, acute variceal bleeding is associated with a high mortality rate. Therefore, timely endoscopic hemostasis and prevention of relapse of bleeding are most important. The treatment goals for acute variceal bleeding are to correct hypovolemia; achieve rapid hemostasis; and prevent early rebleeding, complications related to bleeding, and deterioration of liver function. If variceal bleeding is suspected, treatment with vasopressors and antibiotics should be initiated immediately on arrival to the hospital. Furthermore, to obtain hemodynamic stability, the hemoglobin level should be maintained at >8 g/dL, systolic blood pressure >90 to 100 mm Hg, heart rate <100/min, and the central venous pressure from 1 to 5 mm Hg. When the patient becomes hemodynamically stable, hemostasis should be achieved by performing endoscopy as soon as possible. For esophageal variceal bleeding, endoscopic variceal ligation is usually performed, and for gastric variceal bleeding, endoscopic variceal obturation is performed primarily. If it is considered difficult to achieve hemostasis through endoscopy, salvage therapy may be carried out while keeping the patient hemodynamically stable. PMID:25133116

    In the majority (80%) of patients with acute pancreatitis, the disease is self limiting and, after a few days of withholding feeding and intravenous administration of fluids, patients can again be normally fed orally. In a small percentage of patients, the disease progresses to severe necrotic pancreatitis, with an intense systemic inflammatory response and often with multiple organ dysfunction syndrome. As mortality is high in patients with severe disease and as mortality and morbidity rates are directly related to the failure of establishing a positive nitrogen balance, it is assumed that feeding will improve survival in patients with severe disease. The aim of nutritional support is to cover the elevated metabolic demands as much as possible, without stimulating pancreatic secretion and maximizing self-digestion. The administration of either total parenteral nutrition or jejunal nutrition does not stimulate pancreatic secretion. Recently, a series of controlled clinical studies has been conducted in order to evaluate the effectiveness of enteral nutrition with jejunal administration of the nutritional solution. The results have shown that enteral nutrition, as compared to total parenteral nutrition, was cheaper, safer and more effective as regards the suppression of the immunoinflammatory response, the decrease of septic complications, the need for surgery for the management of the complications of acute pancreatitis and the reduction of the total hospitalization period. It did not seem to affect mortality or the rate of non-septic complications. In conclusion, enteral nutrition should be the preferred route of nutritional support in patients with acute pancreatitis.

    Ecallantide, a recombinant protein that is a selective, highly potent and reversible inhibitor of human plasma kallikrein, is indicated for the treatment of acute attacks of hereditary angioedema (HAE) in patients aged >or=16 years. In the randomized, double-blind, placebo-controlled, multicentre, phase III trial EDEMA3, mean symptom response to treatment at 4 hours (assessed using the Treatment Outcome Score [TOS]; primary endpoint) was significantly greater with a single subcutaneous dose of ecallantide 30 mg than with placebo in patients with acute, moderate to severe attacks of HAE. In addition, the mean change from baseline in symptom severity at 4 hours (assessed using the Mean Symptom Complex Severity [MSCS] scale) was significantly greater with ecallantide than with placebo. At 4 hours in the similarly designed EDEMA4 trial, the mean change from baseline in MSCS score (primary endpoint) and mean TOS were both significantly greater in recipients of a single subcutaneous dose of ecallantide 30 mg than in placebo recipients. Subcutaneous ecallantide 30 mg was generally well tolerated in patients with acute attacks of HAE in the EDEMA3 and EDEMA4 trials. Adverse events were mostly of mild to moderate severity, and no event that was more common in ecallantide than placebo recipients occurred in >10% of patients. PMID:20614949

    Joint injury has been recognized as a potent risk factor for the onset of osteoarthritis. The vast majority of studies using imaging technology for longitudinal assessment of patients following joint injury have focused on the injured knee joint, specifically in patients with anterior cruciate ligament injury and meniscus tears where a high risk for rapid onset of post-traumatic osteoarthritis is well known. Although there are many imaging modalities under constant development, magnetic resonance (MR) imaging is the most important instrument for longitudinal monitoring after joint injury. MR imaging is sensitive for detecting early cartilage degeneration and can evaluate other joint structures including the menisci, bone marrow, tendons, and ligaments which can be sources of pain following acute injury. In this review, focusing on imaging following acute knee trauma, several studies were identified with promising short-term results of osseous and soft tissue changes after joint injury. However, studies connecting these promising short-term results to the development of osteoarthritis were limited which is likely due to the long follow-up periods needed to document the radiographic and clinical onset of the disease. Thus, it is recommended that additional high quality longitudinal studies with extended follow-up periods be performed to further investigate the long-term consequences of the early osseous and soft tissue changes identified on MR imaging after acute knee trauma.

    Severe acute pancreatitis (SAP) develops in about 25% of patients with acute pancreatitis. Severity of acute pancreatitis is linked to the presence of systemic organ dysfunctions and/or necrotizing pancreatitis. Risk factors independently determining the outcome of SAP are early multiorgan failure (MOF), infection of necrosis, and extended necrosis (>50%). Morbidity of SAP is biphasic, in the first week it is strongly related to systemic inflammatory response syndrome while, sepsis due to infected pancreatic necrosis leading to MOF syndrome occurs in the later course after the first week. Contrast-enhanced computed tomography provides the highest diagnostic accuracy for necrotizing pancreatitis when performed after the first week of disease. Patients who suffer early organ dysfunctions or are at risk for developing a severe disease require early intensive care treatment. Antibiotic prophylaxis has not been shown as an effective preventive treatment. Early enteral feeding is based on a high level of evidence, resulting in a reduction of local and systemic infection. Patients suffering infected necrosis causing clinical sepsis are candidates for intervention. Hospital mortality of SAP after interventional or surgical debridement has decreased to below 20% in high-volume centers. PMID:23372306

    Thirty patients with acute myocardial infarction which occurred during sport were investigated to identify the type of sport, prodromata, situations at the onset of disease, habit of exercise, preceding medical evaluation, coronary risk factors, and coronary angiographic findings. Infarction occurred during golf in 12 patients, bowling in 4, gateball in 4, jogging or running in 5, baseball in 2, and tennis or table tennis in 3. The majority of the patients were playing ball games. Twenty-seven patients were men (90%) and 3 were women (10%). All patients had played the same kind of sport for several years. Twenty-four patients had one or more coronary risk factors, and especially 18 patients smoked cigarettes. Nine patients had experienced anterior chest pain but only two patients had received medical evaluation. Coronary angiography was performed in 25 patients (83.3%), revealing single-vessel disease in 14, two-vessel disease in 6, three-vessel disease in 4, and disease of all left main coronary trunks in 1. The acute episode of infarction occurred mainly in spring or fall. Many patients with acute myocardial infarction occurring during sport participate in sports of low or moderate dynamic and low static exercises which are generally regarded safe. Many patients had enjoyed their sports regularly for a long time. Though many patients had coronary risk factors, only a few had received a medical check before their heart attack. PMID:7500263

    Perioperative period is very likely to lead to acute renal failure because of anesthesia (general or perimedullary) and/or surgery which can cause acute kidney injury. Characterization of acute renal failure is based on serum creatinine level which is imprecise during and following surgery. Studies are based on various definitions of acute renal failure with different thresholds which skewed their comparisons. The RIFLE classification (risk, injury, failure, loss, end stage kidney disease) allows clinicians to distinguish in a similar manner between different stages of acute kidney injury rather than using a unique definition of acute renal failure. Acute renal failure during the perioperative period can mainly be explained by iatrogenic, hemodynamic or surgical causes and can result in an increased morbi-mortality. Prevention of this complication requires hemodynamic optimization (venous return, cardiac output, vascular resistance), discontinuation of nephrotoxic drugs but also knowledge of the different steps of the surgery to avoid further degradation of renal perfusion. Diuretics do not prevent acute renal failure and may even push it forward especially during the perioperative period when venous retourn is already reduced. Edema or weight gain following surgery are not correlated with the vascular compartment volume, much less with renal perfusion. Treatment of perioperative acute renal failure is similar to other acute renal failure. Renal replacement therapy must be mastered to prevent any additional risk of hemodynamic instability or hydro-electrolytic imbalance. PMID:24656890

    Background Hordeolum is a common, painful inflammation of the eyelid margin that is usually caused by bacterial infection. The infection affects oil glands of the eyelid and can be internal or external. In many cases, the lesion drains spontaneously and resolves untreated; however, the inflammation can spread to other ocular glands or tissues, and recurrences are common. If unresolved, acute internal hordeolum can become chronic or can develop into a chalazion. External hordeola, also known as styes, were not included in the scope of this review. Objectives The objective of this review was to investigate the effectiveness and safety of nonsurgical treatments for acute internal hordeolum compared with observation or placebo. Search methods We searched CENTRAL (which contains the Cochrane Eyes and Vision Group Trials Register) (The Cochrane Library 2012, Issue 7), Ovid MEDLINE, Ovid MEDLINE In-Process and Other Non-Indexed Citations, Ovid MEDLINE Daily, Ovid OLDMEDLINE, (January 1950 to July 2012), EMBASE (January 1980 to July 2012), Latin American and Caribbean Literature on Health Sciences (LILACS) (January 1982 to July 2012), the metaRegister of Controlled Trials (mRCT) (www.controlled-trials.com), ClinicalTrials.gov (www.clinicaltrials.gov) and the WHO International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en). We did not use any date or language restrictions in the electronic searches for trials. We last searched the electronic databases on 26 July 2012. Selection criteria The selection criteria for this review included randomized or quasi-randomized clinical trials of participants diagnosed with acute internal hordeolum. Studies of participants with external hordeolum (stye), chronic hordeolum, or chalazion were excluded. Nonsurgical interventions of interest included the use of hot or warm compresses, lid scrubs, antibiotics, or steroids compared with observation, placebo, or other active interventions.

    The natural history of idiopathic pulmonary fibrosis (IPF) has been characterized as a steady, predictable decline in lung function over time. Recent evidence suggests that some patients may experience a more precipitous course, with periods of relative stability followed by acute deteriorations in respiratory status. Many of these acute deteriorations are of unknown etiology and have been termed acute exacerbations of IPF. This perspective is the result of an international effort to summarize the current state of knowledge regarding acute exacerbations of IPF. Acute exacerbations of IPF are defined as acute, clinically significant deteriorations of unidentifiable cause in patients with underlying IPF. Proposed diagnostic criteria include subjective worsening over 30 days or less, new bilateral radiographic opacities, and the absence of infection or another identifiable etiology. The potential pathobiological roles of infection, disordered cell biology, coagulation, and genetics are discussed, and future research directions are proposed. PMID:17585107

    In a retrospective analysis of 218 hepatobiliary studies in patients clinically suspected of acute cholecystitis, a rim of increased hepatic activity adjacent to the gallbladder fossa (the rim sign) has been evaluated as a scintigraphic predictor of confirmed acute cholecystitis. Of 28 cases with pathologic confirmation of acute cholecystitis in this series, 17 (60%) demonstrated this sign. When associated with nonvisualization of the gallbladder at 1 hr, the positive predictive value of this photon-intense rim for acute cholecystitis was 94%. When the rim sign was absent, the positive predictive value of nonvisualization of the gallbladder at 1 hr for acute cholecystitis was only 36%. As this sign was always seen during the first hour postinjection, it can, when associated with nonvisualization, reduce the time required for completion of an hepatobiliary examination in suspected acute cholecystitis.

    In a prospective study of 91 patients with acute pancreatitis, computed tomographic (CT) findings were correlated with the clinical type of acute pancreatitis. In acute edematous pancreatitis (63 patients; 16 with repeat CT), CT was normal (28%) or showed inflammation limited to the pancreas (61%). Phlegmonous changes were present in 11%, including one patient with focal pancreatic hemorrhage, indicating that clinically unsuspected hemorrhagic pancreatitis can occur. In acute necrotizing (hemorrhagic, suppurative) pancreatitis (nine patients; eight with repeat CT), no patient had a normal CT scan and 89% had phlegmonous changes. One patient had hemorrhagic pancreatitis and three had abscesses. In acute exacerbation of chronic pancreatitis (10 patients; three with repeat CT), there were pancreatic calcifications (70%), a focal mass (40%), and pancreatic ductal dilation (30%). On follow-up CT, the findings of acute pancreatitis did not always disappear with resolution of the clinical symptons. This was especialy true of phlegmonous pancreatitis, where the CT findings could persist for months.

    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

    Management of critical limb ischemia of acute onset includes surgical embolectomy, bypass grafting, aspiration thrombectomy, thrombolysis, and mechanical thrombectomy followed by treatment of the underlying cause. We present our experience with the use of stents to treat acute embolic/thrombotic occlusions in one iliac and three femoropopliteal arteries. Although this is a small case series, excellent immediate and midterm results suggest that stenting of acute occlusions of the iliac, superficial femoral, and popliteal arteries is a safe and effective treatment option.

    The Atlanta classification of acute pancreatitis was introduced in 1992 and divides patients into mild and severe groups based on clinical and biochemical criteria. Recently, the terminology and classification scheme proposed at the initial Atlanta Symposium have been reviewed and a new consensus statement has been proposed by the Acute Pancreatitis Classification Working Group. Major changes include subdividing acute fluid collections into "acute peripancreatic fluid collection" and "acute post-necrotic pancreatic/peripancreatic fluid collection (acute necrotic collection)" based on the presence of necrotic debris. Delayed fluid collections have been similarly subdivided into "pseudocyst" and "walled of pancreatic necrosis". Appropriate use of the new terms describing the fluid collections is important for management decision-making in patients with acute pancreatitis. The purpose of this review article is to present an overview of complications of the acute pancreatitis with emphasis on their prognostic significance and impact on clinical management and to clarify confusing terminology for pancreatic fluid collections.

    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.

    As the incidence of acute pancreatitis continues to rise, establishing the etiology in order to prevent recurrence is important. Although the etiology of acute pancreatitis is not difficult in the majority of patients, almost a quarter of patients are initially labeled as having idiopathic acute pancreatitis. When confronted with a patient with acute pancreatitis and no clear etiology defined as an absence alcoholism, gallstones (ultrasound and/or MRI), a normal triglyceride level, and absence of tumor, it often appears reasonable to consider a drug as the cause of acute pancreatitis. Over 100 drugs have been implicated by case reports as causing acute pancreatitis. While some of these case reports are well written, many case reports represent poorly written experiences of the clinician simply implicating a drug without a careful evaluation. Over-reliance on case reports while ignoring randomized clinical trials and large pharmacoepidemiologic surveys has led to confusion about drug induced acute pancreatitis. This review will explain that drug induced acute pancreatitis does occur, but it is rare, and over diagnosis leads to misconceptions about the disease resulting in inappropriate patient care, increased litigation and a failure to address the true entity: idiopathic acute pancreatitis.

    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.

Interstitial lung diseases (ILDs) including connective tissue disease (CTD) associated ILD, hypersensitivity pneumonitis, acute eosinophilic pneumonia, drug-induced lung disease and diffuse alveolar haemorrhage need to be differentiated from acute and subacute IIPs. Despite the severe lack of randomized controlled trials for the treatment of acute and subacute IIPs, the mainstream treatment remains corticosteroid therapy. Other potential therapies reported in the literature include corticosteroids and immunosuppression, antibiotics, anticoagulants, neutrophil elastase inhibitor, autoantibody-targeted treatment, antifibrotics and hemoperfusion therapy. With regard to mechanical ventilation, patients in recent studies with acute and subacute IIPs have shown better survival than those in previous studies. Therefore, a careful value-laden decision about the indications for endotracheal intubation should be made for each patient. Noninvasive ventilation may be beneficial to reduce ventilator associated pneumonia. PMID:27123874

  20. Acute Type A Aortic Dissection Missed as Acute Coronary Syndrome

    Although the aortic dissection is not common, its outcome is frequently fatal, and many patients with aortic dissection die before referral to the hospital or any diagnostic testing. The symptoms of aortic dissection can be similar to myocardial ischemia. A 66-year-old male was referred to our hospital with suspicion of aortic dissection after echocardiography done for evaluating his high blood pressure. He had symptoms of acute coronary syndrome two years before and had done coronary angiography. On presentation to our hospital he had a high blood pressure. On reviewing his past medical history and examining, in the film of coronary angiography, the dissection flap in ascending aorta was identified. Although type A aortic dissection is a catastrophic condition with high mortality and requires prompt surgical treatment but in some cases it may be misdiagnosed as acute coronary syndrome. Sometimes against its high mortality when left untreated, patients survive and are diagnosed later in life incidentally. So it is of great importance to have great clinical suspicion for aortic dissection in patients referring to the hospital with chest pain and the predisposing factors. PMID:27437290

  1. Focus on acute diarrhoeal disease

    Diarrhoea is an alteration of normal bowel movement characterized by an increase in the water content, volume, or frequency of stools. Diarrhoea needs to be classified according to the trends over time (acute or chronic) and to the characteristics of the stools (watery, fatty, inflammatory). Secretory diarrhoeas, mostly acute and of viral aetiology in more than 70% of cases, are by far the most important subtype of diarrhoeas in terms of frequency, incidence and mortality (over 2.5 million deaths/year in developing countries). Natural and synthetic opiates such as morphine, codeine, and loperamide which react with endogenous opiates (enkephalins, beta-endorphins, dynorphins) mainly act on intestinal motility and slow down transit. An antidiarrhoeal drug developed in recent years, racecadotril, acts as an enkephalinase inhibitor. Clinical studies have shown that it is just as effective as loperamide in resolving acute diarrhoea but with greater reduction in pain and abdominal distension. Some studies have explored the prevalence of diarrhoea in old age. An epidemiological study carried out in Italy by 133 General Practitioners on 5515 elderly outpatients reported a prevalence of diarrhoea, defined according to the Rome criteria, of 9.1%. Infectious diseases (19%) and drug use (16%) were the most common causes of diarrhoea in old age. Regardless of the cause, the treatment of elderly patients with diarrhoea must include rehydration and nutritional support. Every year, more than 50 million tourists travel from industrialized countries to places where hygiene levels are poor. At least 75% of those travelling for short periods mention health problems, and in particular traveller’s diarrhoea. PMID:19610134

    Acute kidney injury (AKI) is a clinical condition considered to be the consequence of a sudden decrease (> 25%) or discontinuation of renal function. The term AKI is used instead of the previous term acute renal failure, because it has been demonstrated that even minor renal lesions may cause far-reaching consequences on human health. Contemporary classifications of AKI (RIFLE and AKIN) are based on the change of serum creatinine and urinary output. In the developed countries, AKI is most often caused by renal ischemia, nephrotoxins and sepsis, rather than a (primary) diffuse renal disease, such as glomerulonephritis, interstitial nephritis, renovascular disorder and thrombotic microangiopathy. The main risk factors for hospital AKI are mechanical ventilation, use of vasoactive drugs, stem cell transplantation and diuretic-resistant hypervolemia. Prerenal and parenchymal AKI (previously known as acute tubular necrosis) jointly account for 2/3 of all AKI causes. Diuresis and serum creatinine concentration are not early diagnostic markers of AKI. Potential early biomarkers of AKI are neutrophil gelatinase-associated lipocalin (NGAL), cystatin C, kidney injury molecule-1 (KIM-1), interleukins 6, 8 and 18, and liver-type fatty acid-binding protein (L-FABP). Early detection of kidney impairment, before the increase of serum creatinine, is important for timely initiated therapy and recovery. The goal of AKI treatment is to normalize the fluid and electrolyte status, as well as the correction of acidosis and blood pressure. Since a severe fluid overload resistant to diuretics and inotropic agents is associated with a poor outcome, the initiation of dialysis should not be delayed. The mortality rate of AKI is highest in critically ill children with multiple organ failure and hemodynamically unstable patients. PMID:25033598

    Acute shoulder injuries in adults are often initially managed by family physicians. Common acute shoulder injuries include acromioclavicular joint injuries, clavicle fractures, glenohumeral dislocations, proximal humerus fractures, and rotator cuff tears. Acromioclavicular joint injuries and clavicle fractures mostly occur in young adults as the result of a sports injury or direct trauma. Most nondisplaced or minimally displaced injuries can be treated conservatively. Treatment includes pain management, short-term use of a sling for comfort, and physical therapy as needed. Glenohumeral dislocations can result from contact sports, falls, bicycle accidents, and similar high-impact trauma. Patients will usually hold the affected arm in their contralateral hand and have pain with motion and decreased motion at the shoulder. Physical findings may include a palpable humeral head in the axilla or a dimple inferior to the acromion laterally. Reduction maneuvers usually require intra-articular lidocaine or intravenous analgesia. Proximal humerus fractures often occur in older patients after a low-energy fall. Radiography of the shoulder should include a true anteroposterior view of the glenoid, scapular Y view, and axillary view. Most of these fractures can be managed nonoperatively, using a sling, early range-of-motion exercises, and strength training. Rotator cuff tears can cause difficulty with overhead activities or pain that awakens the patient from sleep. On physical examination, patients may be unable to hold the affected arm in an elevated position. It is important to recognize the sometimes subtle signs and symptoms of acute shoulder injuries to ensure proper management and timely referral if necessary. PMID:27419328

    Acute ischemia of the rectum or anal canal resulting in necrosis is extremely uncommon because both the rectum and the anal canal have excellent blood supplies. We present a case with spontaneous necrosis of the anal canal without rectal involvement. Surgical debridement was accomplished, and the recovery was uneventful. The patient was elderly, with probable atherosclerotic arterial disease, and presented with hypotension. Due to the lack of other precipitating factors, the hypoperfusion hypothesis seems to be the most suitable in this case. To the best of our knowledge, no similar cases have been reported in the literature on this subject.

  5. [Etiological factors of acute pancreatitis].

    PubMed

    Spicák, J

    2002-09-01

    Acute pancreatitis develops immediately after the causative impulse, while chronic pancreatitis develops after the long-term action of the noxious agent. A typical representative of acute pancreatitis is biliary pancreatitis, chronic pancreatitis develops in alcoholism and has a long latency. As alcoholic pancreatitis is manifested at first as a rule by a potent attack, it is classified in this stage as acute pancreatitis. The most frequent etiological factors in our civilization are thus cholelithiasis and alcoholism (both account for 20-50% in different studies). The assumed pathogenetic principles in acute biliary pancreatitis are the common canal of both efferent ducts above the obturated papilla, duodenopancreatic reflux and intrapancreatic hypertension. A detailed interpretation is however lacking. The pathogenesis of alcoholic pancreatitis is more complicated. Among others some part is played by changes in the calcium concentration and fusion of cellular membranes. Idiopathic pancreatitis occurs in up to 10%, part of the are due to undiagnosed alcoholism and cholelithiasis. Other etiologies are exceptional. Similarly as in cholelithiasis pancreatitis develops also during other pathological processes in the area of the papilla of Vater such as dysfunction of the sphincter of Oddi, ampulloma and juxtapapillary diverticulum, it is however usually mild. The incidence of postoperative pancreatitis is declining. Its lethality is 30% and the diagnosis is difficult. In the pathogenesis changes of the ion concentration are involved, hypoxia and mechanical disorders of the integrity of the gland. Pancreatitis develops in association with other infections--frequently in mumps, rarely in hepatitis, tuberculosis, typhoid and mycoses. Viral pancreatitis is usually mild. In parasitoses pancreatitis develops due to a block of the papilla Vateri. In hyperparathyroidism chronic pancreatitis is more likely to develop, recent data are lacking. As to dyslipoproteinaemias

    Acute decompensated heart failure may occur de novo, but it most often occurs as an exacerbation of underlying chronic heart failure. Hospitalization for heart failure is usually a harbinger of a chronic disease that will require long-term, ongoing medical management. Leaders in the field generally agree that repeated inpatient admissions for treatment reflect a failure of the health care delivery system to manage the disease optimally. Newer management strategies focus on ameliorating symptoms by optimizing the hemodynamics, restoring neurohormonal balance, and making frequent outpatient adjustments when needed. PMID:24286585

    This article discusses the most common organisms associated with acute hematogenous osteomyelitis in children. Magnetic resonance imaging is extremely important in evaluating the extent of the disease process. Osteomyelitis due to methicillin-resistant Staphylococcus aureus can be extremely difficult to treat and eradicate. It spreads quickly and causes local tissue necrosis. It is also associated with other serious sequelae such as deep venous thrombosis and septic pulmonary emboli. A multidisciplinary approach is needed to treat these infections. Hospital stays are often lengthy, complications are frequent, and patients are often critically ill. [Pediatr Ann. 2016;45(6):e204-e208.]. PMID:27294494

    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

    Drug-induced pancreatitis has been reported rarely. Bortezomib is a selective and reversible proteasome inhibitor used for the treatment of patients with multiple myeloma (MM). Recently, one case report about acute pancreatitis (AP) caused by bortezomib was published in the international literature. Herein we report a case of AP in a 67-year-old male on bortezomib therapy. On the fourth day after the first administration of bortezomib, the patient admitted to the hospital with symptoms of AP. The common etiological factors for AP were all excluded.

    Colloids have been used in varying capacities throughout the history of formula-based burn resuscitation. There is sound experimental evidence that demonstrates colloids' ability to improve intravascular colloid osmotic pressure, expand intravascular volume, reduce resuscitation requirements, and limit edema in unburned tissue following a major burn. Fresh frozen plasma appears to be a useful and effective immediate burn resuscitation fluid but its benefits must be weighed against its costs, and risks of viral transmission and acute lung injury. Albumin, in contrast, is less expensive and safer and has demonstrated ability to reduce resuscitation requirements and possibly limit edema-related morbidity. PMID:27600123

Pancreatitis was established functionally and histomorphologically. The control group of animals did not reveal deviations from the norm after infusion of duodenal content. The authors suggested the presence of pathogenic substances in the duodenal content of animals and sick persons, and these components damaged the pancreas, liver and kidneys by means of blood and lymph ways.

    This article reviews the current knowledge base related to the pharmacological treatments for acute bronchiolitis. Bronchiolitis is a common lower respiratory illness affecting infants worldwide. The mainstays of therapy include airway support, supplemental oxygen, and support of fluids and nutrition. Frequently tried pharmacological interventions, such as ribavirin, nebulized bronchodilators, and systemic corticosteroids, have not been proven to benefit patients with bronchiolitis. Antibiotics do not improve the clinical course of patients with bronchiolitis, and should be used only in those patients with proven concurrent bacterial infection. Exogenous surfactant and heliox therapy also cannot be recommended for routine use, but surfactant replacement holds promise and should be further studied. PMID:19209271

    The current review has summarized current data relevant to the nutritional support of patients with acute pancreatitis. Selection of the most appropriate form of nutritional support for patients with acute pancreatitis is intimately linked to a thorough understanding of the effects of various forms of enteral and parenteral nutrition on physiologic exocrine secretory mechanisms. Two basic concepts have emerged from the multiple studies that have addressed these issues to date: 1, enteral feeds should have low fat composition and be delivered distal to the ligament of Treitz to minimize exocrine pancreatic secretion and 2, parenteral substrate infusions, alone or in combinations similar to those administered during TPN, do not stimulate exocrine pancreatic secretion. From a practical standpoint, most patients with acute pancreatitis are diagnosed by nonoperative means and will manifest some degree of paralytic ileus during the early phase of the disease. Therefore, jejunal feeds are usually not a therapeutic option early in the course of this disease. On the basis of the clinical studies reviewed herein we propose general guidelines for the nutritional support of patients with acute pancreatitis: 1, most patients with mild uncomplicated pancreatitis (one to two prognostic signs) do not benefit from nutritional support; 2, nutritional support should begin early in the course of patients with moderate to severe disease (as soon as hemodynamic and cardiorespiratory stability permit); 3, initial nutritional support should be through the parenteral route and include fat emulsion in amounts sufficient to prevent essential fatty acid deficiency (no objective data exist to recommend specific amino acid formulations); 4, patients requiring operation for diagnosis or complications of the disease should have a feeding jejunostomy placed at the time of operation for subsequent enteral nutrition using a low fat formula, such as Precision HN (Sandoz, 1.3 percent calories as fat

    Kidneys' imaging provides useful information in acute kidney injury (AKI) diagnosis and management. Today, several imaging techniques give information on kidneys anatomy, urinary obstruction, differential diagnosis between AKI and chronic kidney disease (CKD), renal blood flow and glomerular filtration rate. Ultrasound is a safe, non-invasive and repeatable imaging technique so it is widely used in the first level work-up of AKI. The utility of contrast-enhanced computed tomography and magnetic resonance imaging in AKI or in AKI during CKD is limited because of renal toxicity associated with contrast agents used.

    The leading genetic cause of infant mortality is spinal muscular atrophy (SMA), a clinically and genetically heterogeneous group of disorders. Previously we described a domestic cat model of autosomal recessive, juvenile-onset SMA similar to human SMA type III. Here we report results of a whole-genome scan for linkage in the feline SMA pedigree using recently developed species-specific and comparative mapping resources. We identified a novel SMA gene candidate, LIX1, in an ~140-kb deletion on feline chromosome A1q in a region of conserved synteny to human chromosome 5q15. Though LIX1 function is unknown, the predicted secondary structure is compatible with a role in RNA metabolism. LIX1 expression is largely restricted to the central nervous system, primarily in spinal motor neurons, thus offering explanation of the tissue restriction of pathology in feline SMA. An exon sequence screen of 25 human SMA cases, not otherwise explicable by mutations at the SMN1 locus, failed to identify comparable LIX1 mutations. Nonetheless, a LIX1-associated etiology in feline SMA implicates a previously undetected mechanism of motor neuron maintenance and mandates consideration of LIX1 as a candidate gene in human SMA when SMN1 mutations are not found.

    Abstract Few data are present in the literature on the relationship between atorvastatin use and acute pancreatitis. The aim of this study was to explore this issue in Taiwan. Using representative claims data established from the Taiwan National Health Insurance Program, this case–control study consisted of 5810 cases aged 20 to 84 years with a first-time diagnosis of acute pancreatitis during the period 1998 to 2011and 5733 randomly selected controls without acute pancreatitis. Both cases and controls were matched by sex, age, comorbidities, and index year of diagnosing acute pancreatitis. Subjects who at least received 1 prescription for other statins or nonstatin lipid-lowering drugs were excluded from the study. If subjects never had 1 prescription for atorvastatin, they were defined as never use of atorvastatin. Current use of atorvastatin was defined as subjects whose last remaining 1 tablet of atorvastatin was noted ≤7 days before the date of diagnosing acute pancreatitis. Late use of atorvastatin was defined as subjects whose last remaining 1 tablet of atorvastatin was noted >7 days before the date of diagnosing acute pancreatitis. The odds ratio with 95% confidence interval of acute pancreatitis associated with atorvastatin use was calculated by using the logistic regression analysis. The logistic regression analysis revealed that the odds ratio of acute pancreatitis was 1.67 for subjects with current use of atorvastatin (95% confidence interval 1.18, 2.38), when compared with subjects with never use of atorvastatin. The odds ratio decreased to 1.15 for those with late use of atorvastatin (95% confidence interval 0.87, 1.52), but without statistical significance. Current use of atorvastatin is associated with the diagnosis of acute pancreatitis. Clinically, clinicians should consider the possibility of atorvastatin-associated acute pancreatitis when patients present with a diagnosis of acute pancreatitis without a definite etiology but are taking

    Background. Plasmablastic lymphoma (PBL) is a rare B-cell neoplasm. It predominantly occurs in the oral cavity of human immunodeficiency virus (HIV)-positive patients and exhibits a highly aggressive clinical behavior. Case Presentation. We describe an unusual case of a 37-year-old HIV-positive male who presented with acute pancreatitis secondary to multiple peripancreatic masses compressing the pancreas. Histopathological examination of the lesions showed diffuse and cohesive pattern of large B-cells resembling immunoblasts or plasmablasts. The neoplastic cells were positive for BOB1 and MUM1, partially positive for CD79a, and negative for CD20, CD56, CD138, CD3, CD5, AE1/AE3, and HHV8. Epstein-Barr virus-encoded RNA in situ hybridization was positive. These features were consistent with PBL. The patient was initiated on cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) chemotherapy, demonstrating a striking response. Conclusion. To our research, this is the first report of PBL with the initial presentation of acute pancreatitis. The findings in this case suggest that PBL should be included in the differential diagnosis of pancreatic and peripancreatic tumors. PMID:27034868

    2010-01-01

    The greatest advance in pediatric pain medicine is the recognition that untreated pain is a significant cause of morbidity and even mortality after surgical trauma. Accurate assessment of pain in different age groups and the effective treatment of postoperative pain is constantly being refined; with newer drugs being used alone or in combination with other drugs continues to be explored. Several advances in developmental neurobiology and pharmacology, knowledge of new analgesics and newer applications of old analgesics in the last two decades have helped the pediatric anesthesiologist in managing pain in children more efficiently. The latter include administering opioids via the skin and nasal mucosa and their addition into the neuraxial local anesthetics. Systemic opioids, nonsteroidal anti-inflammatory agents and regional analgesics alone or combined with additives are currently used to provide effective postoperative analgesia. These modalities are best utilized when combined as a multimodal approach to treat acute pain in the perioperative setting. The development of receptor specific drugs that can produce pain relief without the untoward side effects of respiratory depression will hasten the recovery and discharge of children after surgery. This review focuses on the overview of acute pain management in children, with an emphasis on pharmacological and regional anesthesia in achieving this goal. PMID:21197314

Recognition of important patterns in age-specific mortality rates has suggested that events early in life, perhaps even prenatally, may have an influence on developing leukemia in childhood. The racial differences evident in mortality, incidence, and immunologic subtype of ALL suggest either differences in exposures to certain factors or differences in responses to those factors by white children. Hereditary factors appear to play a role. Familial and hereditary conditions exist that have high incidences of acute leukemia. Chromosomal anomalies are common in these conditions. Viral infections may play a role by contributing to alteration in genetic material through incorporation of the viral genome. How that virus is dealt with after primary infection seems important. The presence of immunodeficiency may allow wider dissemination or enhanced replication of such viruses, thereby increasing the likelihood of cellular transformation to an abnormal cell. Proliferation of that malignant cell to a clone may depend on other cofactors. Perhaps prolonged exposure to substances like benzene or alkylating agents may enhance these interactions between virus and genetic material. Does this change DNA repair mechanisms. Are viral infections handled differently. Is viral genomic information more easily integrated into host cells. Ionizing radiation has multiple effects. Alteration in genetic material occurs both at the molecular and chromosomal levels. DNA may be altered, lost, or added in the cell's attempt to recover from the injury.

  8. 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

    Immunotherapeutic strategies have become part of standard cancer treatment. Chimeric and humanized antibodies have demonstrated activity against a variety of tumors. Although the humanized anti-CD33 antibody HuM195 has only modest activity against overt acute myeloid leukemia (AML), it can eliminate minimal residual disease in acute promyelocytic leukemia. High-dose radioimmunotherapy with b-particle-emitting isotopes targeting CD33, CD45, and CD66 can potentially allow intensification of antileukemic therapy before hematopoietic stem cell transplantation. Conversely, a-particle immunotherapy with isotopes such as bismuth-213 or actinium-225 offers the possibility of selective tumor cell kill while sparing surrounding normal tissues. Targeted chemotherapy with the anti-CD33- calicheamicin construct gemtuzumab ozogamicin has produced remissions in relapsed AML and appears promising when used in combination with standard chemotherapy for newly diagnosed AML. T-cell recognition of peptide antigens presented on the cell surface in combination with major histocompatibility complex antigen provides another potentially promising approach for the treatment of AML.

  10. Acute ankle sprain: an update.

    PubMed

    Acute ankle injury, a common musculoskeletal injury, can cause ankle sprains. Some evidence suggests that previous injuries or limited joint flexibility may contribute to ankle sprains. The initial assessment of an acute ankle injury should include questions about the timing and mechanism of the injury. The Ottawa Ankle and Foot Rules provide clinical guidelines for excluding a fracture in adults and children and determining if radiography is indicated at the time of injury. Reexamination three to five days after injury, when pain and swelling have improved, may help with the diagnosis. Therapy for ankle sprains focuses on controlling pain and swelling. PRICE (Protection, Rest, Ice, Compression, and Elevation) is a well-established protocol for the treatment of ankle injury. There is some evidence that applying ice and using nonsteroidal antiinflammatory drugs improves healing and speeds recovery. Functional rehabilitation (e.g., motion restoration and strengthening exercises) is preferred over immobilization. Superiority of surgical repair versus functional rehabilitation for severe lateral ligament rupture is controversial. Treatment using semirigid supports is superior to using elastic bandages. Support devices provide some protection against future ankle sprains, particularly in persons with a history of recurrent sprains. Ankle disk or proprioceptive neuromuscular facilitation exercise regimens also may be helpful, although the literature supporting this is limited. PMID:17137000

    Severe pre-eclampsia is a state of acute afterload increase where compensation may be total by use of the Frank-Starling mechanism and/or increased adrenergic drive, or may be uncompensated in a patient with limited or exhausted preload reserve. As such, we are presented with a diverse group of patients and antihypertensive therapy ideally should be individualized. In reality we are dealing with a complex situation because of the presence of the fetus raising concerns about direct effects on the fetus as well as on uteroplacental blood flow. This limits our choice of agents to those with extensive use in pregnancy except in complicated or resistant cases. For these reasons, hydralazine is the antihypertensive agent of choice for treatment of acute hypertensive emergencies in pregnancy. In the complicated case other agents such as sodium nitroprusside or nitroglycerin may be more appropriate and, in these cases, hemodynamic monitoring should be performed to allow not only greater safety, but also to tailor therapy to the individual hemodynamic profile.

    2016-05-01

    Acute kidney injury (AKI) refers to any acute decrease in glomerular filtration rate, regardless of etiology. Staging of AKI has been recommended to stratify AKI patients according to severity of the condition, based on serum creatinine level and urine output. Classification of AKI into prerenal, intrinsic renal, and postrenal etiologies is helpful in differential diagnosis and management. AKI in hospitalized patients typically occurs due to decreased renal perfusion. Drug-induced, contrast-associated, postoperative, and sepsis-associated AKI also can occur. Clinical assessment of a patient with AKI involves a medical record review, thorough history and physical examination, urinary and blood tests, renal imaging, and, in some instances, renal biopsy. Contrast-induced nephropathy is a common iatrogenic etiology of AKI associated with administration of intravenous iodinated contrast media. Measures to prevent AKI should be taken before administration of intravenous iodinated contrast. AKI can result in many short- and long-term complications, including chronic kidney disease and end-stage renal disease. Appropriate treatment of AKI patients involves management of the underlying etiology, when possible, and use of nondialytic and dialytic therapies. PMID:27163760

    Background. Plasmablastic lymphoma (PBL) is a rare B-cell neoplasm. It predominantly occurs in the oral cavity of human immunodeficiency virus (HIV)-positive patients and exhibits a highly aggressive clinical behavior. Case Presentation. We describe an unusual case of a 37-year-old HIV-positive male who presented with acute pancreatitis secondary to multiple peripancreatic masses compressing the pancreas. Histopathological examination of the lesions showed diffuse and cohesive pattern of large B-cells resembling immunoblasts or plasmablasts. The neoplastic cells were positive for BOB1 and MUM1, partially positive for CD79a, and negative for CD20, CD56, CD138, CD3, CD5, AE1/AE3, and HHV8. Epstein-Barr virus-encoded RNA in situ hybridization was positive. These features were consistent with PBL. The patient was initiated on cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) chemotherapy, demonstrating a striking response. Conclusion. To our research, this is the first report of PBL with the initial presentation of acute pancreatitis. The findings in this case suggest that PBL should be included in the differential diagnosis of pancreatic and peripancreatic tumors. PMID:27034868

    Swallowing dysfunction is common after stroke. More than 50% of the 665 thousand stroke survivors will experience dysphagia acutely of which approximately 80 thousand will experience persistent dysphagia at 6 months. The physiologic impairments that result in post-stroke dysphagia are varied. This review focuses primarily on well-established dysphagia treatments in the context of the physiologic impairments they treat. Traditional dysphagia therapies including volume and texture modifications, strategies such as chin tuck, head tilt, head turn, effortful swallow, supraglottic swallow, super-supraglottic swallow, Mendelsohn maneuver and exercises such as the Shaker exercise and Masako (tongue hold) maneuver are discussed. Other more recent treatment interventions are discussed in the context of the evidence available. PMID:26484001

    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

    Acute-on-chronic liver failure is a clinical entity with high risk of mortality. These patients can have severe liver dysfunction complicated with multiple organ failure. Liver transplantation is the definitive treatment for these patients. Literature regarding management of acute liver failure with special emphasis on liver transplantation was reviewed. Lessons learnt from the management of patients with acute liver failure which could be extrapolated to the management of patients with acute-on-chronic liver failure are discussed. Significant improvement in outcomes of acute liver failure has been reported across the world. Several aspects in transplantation for acute liver failure were found to be relevant to the management of acute-on-chronic liver failure. These include defining criteria to identify patients needing early liver transplantation, prioritizing patients with acute liver failure on the waiting list, defining when to abandon transplantation in acute liver failure, emphasis on graft quality and the need for a multi-disciplinary approach to manage multiple organ dysfunction. Useful lessons can be learnt from the progress made in the management of acute liver failure and these can be extrapolated to the management of patients with acute-on-chronic liver failure.

    2016-01-01

    Acute kidney injury (AKI) is a common complication after acute stroke and is an independent predictor of both early and long-term mortality after acute stroke. Acute kidney injury is associated with increased mortality in haemorrhagic stroke patients. This cross sectional observational study was conducted in Nephrology, Neuromedicine and Medicine department of Mymensingh Medical College & Hospital, Mymensingh from July 2012 to June 2014. A total of 240 patients with newly detected acute stroke confirmed by CT scan of brain were included in this study. According to this study, 15.42% of acute stroke patients developed AKI. Among the patients with haemorrhagic stroke 21.87% developed AKI while only 13.07% patients with ischaemic stroke developed AKI. So, early diagnosis and management of AKI in patients with acute stroke especially in haemorrhagic stroke is very important to reduce the morbidity and mortality of these patients. PMID:26931240

    Renal dysfunction in cholestatic liver disease is multifactorial. Acute kidney injury may develop secondary to renal vasoconstriction in the setting of peripheral vasodilation and relative hypovolemia, tubular obstruction by bile casts, and direct tubular toxicity from bile. Anabolic steroids are frequently used by athletes to boost endurance and increase muscle mass. These agents are a recently recognized cause of hepatotoxicity and jaundice and may lead to acute kidney injury. To increase awareness about this growing problem and to characterize the pathology of acute kidney injury in this setting, we report on a young male who developed acute kidney injury in the setting of severe cholestatic jaundice related to ingestion of anabolic steroids used for bodybuilding. Kidney biopsy showed bile casts within distal tubular lumina, filamentous bile inclusions within tubular cells, and signs of acute tubular injury. This report supports the recently re-emerged concept of bile nephropathy cholemic nephrosis. PMID:26587777

    The Institute of Medicine, in its 2001 Crossing the Quality Chasm report, recommended greater integration and coordination as a component of a transformed health care system, yet relationships between acute and post-acute providers have remained weak. With payment reforms that hold hospitals and health systems accountable for the total costs of care and readmissions, the dynamic between acute and post-acute providers is changing. In this article, we outline the internal and market factors that will drive health systems’ decisions about whether and how they integrate with post-acute providers. Enhanced integration between acute and post-acute providers should reduce variation in post-acute spending. PMID:27148428

    Acute decompensated heart failure (ADHF) continues to increase in prevalence and is associated with substantial mortality and morbidity including frequent hospitalizations. The American Heart Association is predicting that more than eight million Americans will have heart failure by 2030 and that the total direct costs associated with the disease will rise from $21 billion in 2012 to $70 billion in 2030. The increase in the prevalence and cost of HF is primarily the result of shifting demographics and a growing population. Although many large, randomized, controlled clinical trials have been conducted in patients with chronic heart failure, it was not until recently that a growing number of studies began to address the management of ADHF. It is the intent of this review to update the clinician regarding the evaluation and optimal management of ADHF. PMID:24251454

This review focuses on key management issues including giving appropriate oxygen therapy, treatment of the underlying aetiology as well as any precipitant factors and provision of assisted ventilation if required. Ventilatory assistance can be provided both invasively and non‐invasively and the indications for either or both forms of assisted ventilation are discussed. Further emphasis is needed regarding advanced directives of care and clinicians should be aware of ethical issues regarding assisted ventilation. PMID:16822920

    Alberta initiated the Acute Care Funding Project (ACFP) in 1988, a new hospital funding system that institutes case mix budgeting adjustments to the global budget so that hospitals can be treated more equitably. The initiative is a significant departure in principle from the former method of funding. The ACFP is summarized and critiqued, and focuses on the inpatient side of the picture. The various elements of the project are discussed, such as the hospital performance index, the hospital performance measure, the Refined Diagnostic Related Group, case weights, typical and outlier cases, and the costing mechanisms. Since its implementation, the ACFP has undergone substantial changes; these are discussed, as well as some of the problems that still need to be addressed. Overall, the system offers incentives to reduce length of stay and to increase the efficiency with which inpatient care is provided. PMID:10121446

    2015-01-01

    In acute stroke, the major factor for recovery is the early use of thrombolysis aimed at arterial recanalization and reperfusion of ischemic brain tissue. Subsequently, neurorehabilitative training critically improves clinical recovery due to augmention of postlesional plasticity. Neuroimaging and electrophysiology studies have revealed that the location and volume of the stroke lesion, the affection of nerve fiber tracts, as well as functional and structural changes in the perilesional tissue and in large-scale bihemispheric networks are relevant biomarkers of post-stroke recovery. However, associated disorders, such as mood disorders, epilepsy, and neurodegenerative diseases, may induce secondary cerebral changes or aggravate the functional deficits and, thereby, compromise the potential for recovery.

    Nine children over 20 months of age had acute osteomyelitis of the epiphysis of a long bone. The clinical features varied, but all of the patients had pain at the infected site and an elevated erythrocyte sedimentation rate. The distal femur was involved in seven cases, the proximal tibian in two, and the proximal humerus in one. In two patients there was a contiguous metaphyseal lesion, while the other seven patients (eight sites) had lesions limited to the epiphysis. Bone scintigraphy clearly identified the infected sites in all seven patients in whom it was performed, and allowed an early diagnosis in four cases. Radiographs showed a lytic lesion of the epiphysis that corresponded to the scintigraphic findings in all cases. The epiphysis of the child should be recognized as another site of hematogenous osteomyelitis.

    New diagnostic and therapeutic developments have led to an innovative approach to stroke therapy. The slogan "time is brain" emphasizes that stroke is a medical emergency comparable to myocardial infarction. The stroke unit conception is an evidence based therapy for all stroke patients and improves outcome significantly. The monitoring of vital signs and the management of stroke specific complications are highly effective. Early secondary prophylaxis reduces the risk of recurrence. The effect of CT based thrombolysis within the time window of 4,5 h has been substantiated by current data. Stroke MRI holds the promise for an improved therapy by patient stratification and by opening the time window. Interventional recanalisation, vascular interventions and hemicraniectomy complement the therapeutic options in the acute phase of stroke. PMID:19838656

    2015-01-01

    Summary The diagnosis of acute pancreatitis requires the presence of at least two of the three diagnostic criteria – characteristic abdominal pain, elevated serum amylase or lipase, and radiological evidence of pancreatitis. Serum concentrations of amylase and lipase rise within hours of the pancreatic injury. A threshold concentration 2–4 times the upper limit of normal is recommended for diagnosis. Serum lipase is now the preferred test due to its improved sensitivity, particularly in alcohol-induced pancreatitis. Its prolonged elevation creates a wider diagnostic window than amylase. Neither enzyme is useful in monitoring or predicting the severity of an episode of pancreatitis in adults. New biomarkers including trypsinogen and elastase have no significant advantage over amylase or lipase. PMID:26648641

    Propionic Acidemia or aciduria is an intoxication-type disorder of organic metabolism. Patients deteriorate in times of increased metabolic demand and subsequent catabolism. Metabolic decompensation can manifest with lethargy, vomiting, coma and death if not appropriately treated. On January 28-30, 2011 in Washington, D.C., Children's National Medical Center hosted a group of clinicians, scientists and parental group representatives to design recommendations for acute management of individuals with Propionic Acidemia. Although many of the recommendations are geared towards the previously undiagnosed neonate, the recommendations for a severely metabolically decompensated individual are applicable to any known patient as well. Initial management is critical for prevention of morbidity and mortality. The following manuscript provides recommendations for initial treatment and evaluation, a discussion of issues concerning transport to a metabolic center (if patient presents to a non-metabolic center), acceleration of management and preparation for discharge.

    2015-01-01

    Purpose of review Recent advances in epigenetics indicate the involvement of several epigenetic modifications in the pathogenesis of acute kidney injury (AKI). The purpose of this review is to summarize our understanding of recent advances in epigenetic regulation of AKI and provide mechanistic insight into the role of acetylation, methylation, and microRNA expression in the pathological processes of AKI. Recent findings Enhancement of protein acetylation by pharmacological inhibition of histone deacetylases (HDACs) leads to more severe tubular injury and impairment of renal structural and functional recovery. The changes in promoter DNA methylation occur in the kidney with ischemia/reperfusion. microRNA expression is associated with regulation of both renal injury and regeneration after AKI. Summary Recent studies on epigenetic regulation indicate that acetylation, methylation, and microRNA expression are critically implicated in the pathogenesis of AKI. Strategies targeting epigenetic processes may hold a therapeutic potential for patients with AKI. PMID:26050122

    2009-01-01

    Acute kidney injury (AKI) is a common condition with a high risk of death. The standard metrics used to define and monitor the progression of AKI, such as serum creatinine and blood urea nitrogen levels, are insensitive, nonspecific, and change significantly only after significant kidney injury and then with a substantial time delay. This delay in diagnosis not only prevents timely patient management decisions, including administration of putative therapeutic agents, but also significantly affects the preclinical evaluation of toxicity thereby allowing potentially nephrotoxic drug candidates to pass the preclinical safety criteria only to be found to be clinically nephrotoxic with great human costs. Studies to establish effective therapies for AKI will be greatly facilitated by two factors: (a) development of sensitive, specific, and reliable biomarkers for early diagnosis/prognosis of AKI in preclinical and clinical studies, and (b) development and validation of high-throughput innovative technologies that allow rapid multiplexed detection of multiple markers at the bedside.

    Severe acute malnutrition (SAM) is associated with increased severity of common infectious diseases, and death amongst children with SAM is almost always as a result of infection. The diagnosis and management of infection are often different in malnourished versus well-nourished children. The objectives of this brief are to outline the evidence underpinning important practical questions relating to the management of infectious diseases in children with SAM and to highlight research gaps. Overall, the evidence base for many aspects covered in this brief is very poor. The brief addresses antimicrobials; antipyretics; tuberculosis; HIV; malaria; pneumonia; diarrhoea; sepsis; measles; urinary tract infection; nosocomial Infections; soil transmitted helminths; skin infections and pharmacology in the context of SAM. The brief is structured into sets of clinical questions, which we hope will maximise the relevance to contemporary practice. PMID:25475887

    Intranasal drug administration is an easy, well-tolerated, noninvasive transmucosal route that avoids first-pass metabolism in the liver. The nasal mucosa provides an extensive, highly vascularized surface of pseudostratified ciliated epithelium. It secretes mucus that is subjected to mucociliary movement that can affect the time of contact between the drug and the surface. Absorption is influenced by anatomical and physiological factors as well as by properties of the drug and the delivery system. We review the literature on intranasal administration of fentanyl, meperidine, diamorphine, and butorphanol to treat acute pain. The adverse systemic effects are similar to those described for intravenous administration, the most common being drowsiness, nausea, and vomiting. Local effects reported are a burning sensation with meperidine and a bad taste. PMID:17302079

    The initial section deals with basic sciences; among the various topics briefly discussed are the anatomical features of ophthalmic, central retinal and cilioretinal arteries which may play a role in acute retinal arterial ischemic disorders. Crucial information required in the management of central retinal artery occlusion (CRAO) is the length of time the retina can survive following that. An experimental study shows that CRAO for 97 minutes produces no detectable permanent retinal damage but there is a progressive ischemic damage thereafter, and by 4 hours the retina has suffered irreversible damage. In the clinical section, I discuss at length various controversies on acute retinal arterial ischemic disorders. Classification of acute retinal arterial ischemic disorders These are of 4 types: CRAO, branch retinal artery occlusion (BRAO), cotton wools spots and amaurosis fugax. Both CRAO and BRAO further comprise multiple clinical entities. Contrary to the universal belief, pathogenetically, clinically and for management, CRAO is not one clinical entity but 4 distinct clinical entities – non-arteritic CRAO, non-arteritic CRAO with cilioretinal artery sparing, arteritic CRAO associated with giant cell arteritis (GCA) and transient non-arteritic CRAO. Similarly, BRAO comprises permanent BRAO, transient BRAO and cilioretinal artery occlusion (CLRAO), and the latter further consists of 3 distinct clinical entities - non-arteritic CLRAO alone, non-arteritic CLRAO associated with central retinal vein occlusion and arteritic CLRAO associated with GCA. Understanding these classifications is essential to comprehend fully various aspects of these disorders. Central retinal artery occlusion The pathogeneses, clinical features and management of the various types of CRAO are discussed in detail. Contrary to the prevalent belief, spontaneous improvement in both visual acuity and visual fields does occur, mainly during the first 7 days. The incidence of spontaneous visual

    Summary A major change is needed in the entrenched culture of routinely administering high-concentration oxygen to acutely ill patients regardless of need. Oxygen is a drug that should be prescribed for specific indications. There should be a documented target range for oxygen saturation, and regular monitoring of the patient’s response. There are risks from unrelieved hypoxaemia due to insufficient oxygen therapy, and from provoked hyperoxaemia due to excessive oxygen therapy. Oxygen therapy should therefore be titrated so that the saturation is within a range that avoids these risks. If oxygen requirements are increasing, the clinician should review the patient and consider transfer to a higher level of care. If oxygen requirements are decreasing, consider reducing or discontinuing oxygen therapy. PMID:26648631

    Despite modern intensive care management, acute mediastinitis is still associated with a high morbidity and mortality (up to approximately 40 %). Effective antibiotic therapy, intensive care management, elimination of the causative sources of infection and drainage of the affected mediastinal compartments are the cornerstones of therapy in a multidisciplinary treatment concept. Early diagnosis, prompt and uncompromising initial therapy and planned computed tomography (CT) control after the first stages of therapy in order to decide on the necessity for surgical re-interventions are essential for achieving optimal results. Knowledge of the specific anatomical characteristics is crucial for the understanding of this disease and its treatment; therefore, the current knowledge on fascial layers and interstitial spaces from the neck to the mediastinum is described and discussed. A possible foudroyant spread of the infection, especially within the posterior mediastinum, has to be anticipated. The approach to the mediastinum depends on the mediastinal compartments affected, on the causative disease and on the patient's clinical situation. The surgical approach should be adapted to the particular clinical situation of the individual patient and to the surgical experience of the surgeon. When in doubt, the more invasive approach to the mediastinum, such as bilateral thoracotomy, is recommended. An ascending mediastinitis due to pancreatitis is a very rare condition; however, as chest pains are often the main clinical sign surgeons should be aware of this differential diagnosis. An intraoperative brown-black serous fluid in the mediastinal tissue is virtually pathognomonic. The treatment results of esophageal perforation as the most frequent cause of mediastinitis have been improved by integration of various interventional procedures. Hyperbaric oxygen therapy or immunoglobulin treatment can play an auxiliary role in selected patients with acute mediastinitis. PMID

    Fibrinolysis has opened up a new avenue in the treatment of acute myocardial infarction (AMI). In principle, the rate of reperfusion depends on the type of compound used, the mode of administration and the time between onset of symptoms and the beginning of treatment. With intracoronary streptokinase the reperfusion rate is of the order of 85%. Intravenous urokinase administered as a bolus results in a reopening rate of 50-60%; a similar rate of reperfusion is achieved with rt-PA as infusion, while i.v. streptokinase produces about 50% reopened coronary vessels. The final infarct size is decreased in 70% of patients if fibrinolysis is initiated within 2.5 hours after the onset of symptoms and followed by reopening of the occluded vessel. This results in a lowering of in-hospital mortality, which in various studies is of the order of 45-60%.- Bearing in mind the contraindications, fibrinolysis should be initiated within 3 hours. Hemodynamic improvement by a decrease of infarct size may also be achieved beyond 3 hours in large anterior myocardial infarctions and in posterior infarctions with cardiogenic shock. Early initiation of thrombolysis is of major importance in improving left ventricular function and lowering mortality following acute myocardial infarction. Therefore, prehospital thrombolytic therapy should be considered. - In the postinfarction phase coronary angiography is indicated in patients with angina at rest, stable angina of ECG signs of ischemia. In this situation transfer to a specialized cardiology division for possible percutaneous transluminal angioplasty is indicated. - Reocclusion after successful thrombolysis occurs in 20-30%, and it is therefore important to avoid reinfarction to improve the long term prognosis after AMI.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:3321420

  8. The dynamics of acute inflammation

    NASA Astrophysics Data System (ADS)

    Kumar, Rukmini

    The acute inflammatory response is the non-specific and immediate reaction of the body to pathogenic organisms, tissue trauma and unregulated cell growth. An imbalance in this response could lead to a condition commonly known as "shock" or "sepsis". This thesis is an attempt to elucidate the dynamics of acute inflammatory response to infection and contribute to its systemic understanding through mathematical modeling and analysis. The models of immunity discussed use Ordinary Differential Equations (ODEs) to model the variation of concentration in time of the various interacting species. Chapter 2 discusses three such models of increasing complexity. Sections 2.1 and 2.2 discuss smaller models that capture the core features of inflammation and offer general predictions concerning the design of the system. Phase-space and bifurcation analyses have been used to examine the behavior at various parameter regimes. Section 2.3 discusses a global physiological model that includes several equations modeling the concentration (or numbers) of cells, cytokines and other mediators. The conclusions drawn from the reduced and detailed models about the qualitative effects of the parameters are very similar and these similarities have also been discussed. In Chapter 3, the specific applications of the biologically detailed model are discussed in greater detail. These include a simulation of anthrax infection and an in silico simulation of a clinical trial. Such simulations are very useful to biologists and could prove to be invaluable tools in drug design. Finally, Chapter 4 discusses the general problem of extinction of populations modeled as continuous variables in ODES is discussed. The average time to extinction and threshold are estimated based on analyzing the equivalent stochastic processes.

    Black patients receiving dialysis for end-stage renal disease in the United States have lower mortality rates than white patients. Whether racial differences exist in mortality after acute renal failure is not known. We studied acute renal failure in patients hospitalized between 2000 and 2003 using the Nationwide Inpatient Sample and found that black patients had an 18% (95% confidence interval [CI] 16 to 21%) lower odds of death than white patients after adjusting for age, sex, comorbidity, and the need for mechanical ventilation. Similarly, among those with acute renal failure requiring dialysis, black patients had a 16% (95% CI 10 to 22%) lower odds of death than white patients. In stratified analyses of patients with acute renal failure, black patients had significantly lower adjusted odds of death than white patients in settings of coronary artery bypass grafting, cardiac catheterization, acute myocardial infarction, congestive heart failure, pneumonia, sepsis, and gastrointestinal hemorrhage. Black patients were more likely than white patients to be treated in hospitals that care for a larger number of patients with acute renal failure, and black patients had lower in-hospital mortality than white patients in all four quartiles of hospital volume. In conclusion, in-hospital mortality is lower for black patients with acute renal failure than white patients. Future studies should assess the reasons for this difference. PMID:17855647

    Since the introduction of /sup 99m/Tc-labeled cholescintigraphic agents in the mid-1970s, there has been extensive investigation of their role in the evaluation of biliary tract disorders. These agents accurately assess the patency of the cystic and common bile ducts, and to date, their greatest impact has been on the diagnostic evaluation of suspected acute cholecystitis. This article reviews the use of /sup 99m/Tc-iminodiacetic acid (IDA) derivatives in acute and chronic cholecystitis. Since acute cholecystitis is characterized by cystic duct obstruction, failure of the gallbladder to visualize following /sup 99m/Tc-IDA administration is indicative of cystic duct obstruction and acute cholecystitis. Using this approach, cholescintigraphy has been shown to be highly sensitive, specific, and efficacious in the diagnosis of acute cholecystitis. Cholescintigraphy is now the procedure of choice for the detection of acute cholecystitis. Unlike its successful applications in acute cholecystitis, cholescintigraphy appears of limited value in chronic cholecystitis. Certain circumstances where cholescintigraphy is of value in chronic cholecystitis are discussed. Whether or not cholescintigraphy may play a greater role in the future in elucidating the pathogenesis of chronic cholecystitis by assessment of biliary kinetics remains unanswered.

    Acute kidney injury (AKI) activates pathways of cell death and cell proliferation. Although seemingly discrete and unrelated mechanisms, these pathways can now be shown to be connected and even to be controlled by similar pathways. The dependence of the severity of renal-cell injury on cell cycle pathways can be used to control and perhaps to prevent acute kidney injury. This review is written to address the correlation between cellular life and death in kidney tubules, especially in acute kidney injury. PMID:19536080

    Acute treatment of scapholunate instability is important to prevent future complications of dorsal intercalated segment instability and scapholunate advanced collapse. An understanding of the fundamental normal and abnormal mechanics of this problem is vital. Diagnosis in the acute phase is based on clinical and radiographic findings and treatment focuses on primary scapholunate interosseous ligament repair with a reinforcing dorsal capsulodesis. Suture anchor repair with a modified "double-dorsal" capsulodesis is described. Current data show that open repair is a viable option in the acute setting with most patients demonstrating good to excellent functional, clinical, and radiographic results. PMID:26205704

    This article reviews advances in the management of acute pancreatitis. Medical treatment has been primarily supportive for this diagnosis, and despite extensive research efforts, there are no pharmacologic therapies that improve prognosis. The current mainstay of management, notwithstanding the ongoing debate regarding the volume, fluid type, and rate of administration, is aggressive intravenous fluid resuscitation. Although antibiotics were used consistently for prophylaxis in severe acute pancreatitis to prevent infection, they are no longer used unless infection is documented. Enteral nutrition, especially in patients with severe acute pancreatitis, is considered a cornerstone in management of this disease. PMID:26895677

    Iron is an essential metal involved in several major cellular processes required to maintain life. Because of iron's ability to cause oxidative damage, its transport, metabolism, and storage is strictly controlled in the body, especially in the small intestine, liver, and kidney. Iron plays a major role in acute kidney injury and has been a target for therapeutic intervention. However, the therapies that have been effective in animal models of acute kidney injury have not been successful in human beings. Targeting iron trafficking via ferritin, ferroportin, or hepcidin may offer new insights. This review focuses on the biology of iron, particularly in the kidney, and its implications in acute kidney injury. PMID:27085736

    Malignancy is a common cause of disseminated intravascular coagulation and usually presents as a chronic disorder in solid organ tumours. We present a rare case of recurrent acute disseminated intravascular coagulation in neuroendocrine carcinoma after manipulation, firstly, by core biopsy and, later, by cytotoxic therapy causing a release of procoagulants and cytokines from lysed tumour cells. This is reminiscent of tumour lysis syndrome where massive quantities of intracellular electrolytes and nucleic acid are released, causing acute metabolic imbalance and renal failure. This case highlights the potential complication of acute disseminated intravascular coagulation after trauma to malignant cells. PMID:23139666

These patients experienced a variety of problems: acute gastrointestinal symptoms, central and peripheral neurotoxicity, bone marrow suppression, hepatic toxicity, and mild mucous membrane and cutaneous changes. Although located adjacent to an abandoned mine, the well water had been tested for microorganisms only and was found to be safe. Regulations for testing of water from private wells for fitness to drink are frequently nonexistent, or only mandate biologic tests for microorganisms. Well water, particularly in areas near mining activity, should be tested for metals.

    We report a 57-year old man with diabetes mellitus and hypertension who presented with acute HIV infection. Routine blood tests showed an elevated blood urea nitrogen and creatinine. Renal biopsy showed acute tubular nephropathy, which has not been reported to occur during acute HIV infection, in the absence of rhabdomyolysis or multiple organ system failure. Antiretroviral therapy was initiated. His renal failure gradually resolved without further intervention. At one year of follow-up his HIV RNA was undetectable, and his renal function was normal. The case illustrates a rare manifestation of acute HIV infection - acute renal failure - in an older man with diabetes and hypertension. In this setting acute kidney injury might mistakenly have been attributed to his chronic comorbidities, and this case supports early HIV-1 testing in the setting of a high index of suspicion.

    The role of liver transplantation (LT) in acute liver failure (ALF) complicated by severe acute pancreatitis is still unclear. We here report a case of deceased-donor LT for idiopathic ALF accompanied by severe acute pancreatitis. A 58-year-old man with no history of liver disease presented with idiopathic ALF and acute pancreatitis. After careful consideration, he received a liver from a deceased donor. Following surgery, the patient's liver function rapidly reverted to normal level and the acute pancreatitis simultaneously subsided. The patient later developed a pancreatic pseudocyst, which was treated successfully with combination interventional radiology. LT can be considered for ALF associated with severe acute pancreatitis if there is no clinical evidence of an absolute contraindication for organ transplantation, such as systemic or local infection. Moreover, we recommend a close follow-up by ultrasonography to allow early detection and treatment of pancreatic pseudocysts following surgery. PMID:27600056

    Diagnosis of acute leukemia during pregnancy presents significant medical challenges. Pancytopenia, caused by bone marrow substitution with leukemic cells, impairs maternal and fetal health. Chemotherapeutic agents required to be immediately used to save the mother's life are likely to adversely affect fetal development and outcome, especially if administered at an early gestational stage. Patients diagnosed with acute leukemia during the first trimester are, therefore, recommended to undergo pregnancy termination. At later gestational stages, antileukemic therapy can be administered, although in this case, fetal outcome is still associated with increased incidence of growth restriction and loss. Special attention to the issue of future reproduction, adopting a personalized fertility preservation approach, is required.

    2014-06-01

    Acute macular neuroretinopathy (AMNR) is a rare disorder characterised by acute onset of unilateral or bilateral visual impairment associated with reddish-brown wedge-shaped outer macular lesions. It is more frequently reported in young females and though the pathophysiology remains unclear, factors reported in association with its onset include post-viral illness and vasoconstrictor use. We report a case of AMNR in an 18-year old female patient presenting with a 2-day history of acute painless blurring of central vision bilaterally, following 1 month of preceding flu-like illness. For 1 week prior to presentation, the patient had taken large doses of oral preparations containing phenylephrine hydrochloride. In addition to demonstrating characteristic optical coherence tomography findings seen in AMNR, we illustrate some rarely seen acute ophthalmoscopic features. Based on associations from this case, we add further insight into the pathophysiology of this condition which remains poorly understood. PMID:24037593

    Drugs, toxins, and infections are known to cause acute eosinophilic pneumonia. Daptomycin and minocycline are the commonly reported antibiotics associated with acute eosinophilic pneumonia. In this study, we present a case of imipenem/cilastatin-induced acute eosinophilic pneumonia. The patient presented with fever, acute hypoxic respiratory distress, and diffuse ground-glass opacities on the chest CT a day after the initiation of imipenem/cilastatin. Patient also developed peripheral eosinophilia. A reinstitution of imipenem/cilastatin resulted in recurrence of the signs and symptoms. A bronchoscopy with bronchoalveolar lavage showed 780 nucleated cells/mm(3) with 15% eosinophil. The patient's clinical condition improved significantly after the discontinuation of imipenem/cilastatin therapy and the treatment with corticosteroid. PMID:26944380

    Background: Acute appendicitis is the most common cause of acute abdomen. Approximately 7% of the population will be affected by this condition during full life. The development of AIR score may contribute to diagnosis associating easy clinical criteria and two simple laboratory tests. Aim: To evaluate the score AIR (Appendicitis Inflammatory Response score) as a tool for the diagnosis and prediction of severity of acute appendicitis. Method: Were evaluated all patients undergoing surgical appendectomy. From 273 patients, 126 were excluded due to exclusion criteria. All patients were submitted o AIR score. Results: The value of the C-reactive protein and the percentage of leukocytes segmented blood count showed a direct relationship with the phase of acute appendicitis. Conclusion: As for the laboratory criteria, serum C-reactive protein and assessment of the percentage of the polymorphonuclear leukocytes count were important to diagnosis and disease stratification.

    2011-01-01

    MR perfusion imaging offers the potential for measuring brain perfusion in acute stroke patients, at a time when treatment decisions based upon these measurements may affect outcomes dramatically. Rapid advancements in both acute stroke therapy and perfusion imaging techniques have resulted in continuing redefinition of the role that perfusion imaging should play in patient management. This review first discusses the basic pathophysiology of acute stroke, with specific attention to alterations in the various perfusion-related parameters that can be studied by MR perfusion imaging. Although these parameters are sometimes treated as somewhat interchangeable, they reveal greatly different information about brain perfusion. Therefore, subsequent discussion of the utility of different kinds of perfusion images focuses on the differences between them, as well as important artifacts that can complicate their interpretation. Finally, research on the continually evolving role of MR perfusion imaging in acute stroke care is summarized. PMID:21640299

    Treatment of acute stroke is changing, as endovascular intervention becomes an important adjunct to tissue plasminogen activator. An increasing number of sophisticated physiologic imaging techniques have unique advantages and applications in the evaluation, diagnosis, and treatment-decision making of acute ischemic stroke. In this review, we first highlight the strengths, weaknesses, and possible indications for various stroke imaging techniques. How acute imaging findings in each modality have been used to predict functional outcome is discussed. Furthermore, there is an increasing emphasis on using these state-of-the-art imaging modalities to offer maximal patient benefit through IV therapy, endovascular thrombolytics, and clot retrieval. We review the burgeoning literature in the determination of stroke treatment based on acute, physiologic imaging findings. PMID:26063695

    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.

    2015-08-01

    Acute heart failure is globally one of most frequent reasons for hospitalization and still represents a challenge for the choice of the best treatment to improve patient outcome. According to current international guidelines, as soon as patients with acute heart failure arrive at the emergency department, the common therapeutic approach aims to improve their signs and symptoms, correct volume overload, and ameliorate cardiac hemodynamics by increasing vital organ perfusion. Recommended treatment for the early management of acute heart failure is characterized by the use of intravenous diuretics, oxygen, and vasodilators. Although these measures ameliorate the patient's symptoms, they do not favorably impact on short- and long-term mortality. Consequently, there is a pressing need for novel agents in acute heart failure treatment with the result that research in this field is increasing worldwide. PMID:26088867

    Acute pelvic pain in pregnancy presents diagnostic and therapeutic challenges. Standard imaging techniques need to be adapted to reduce harm to the foetus from X-rays because of 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 foetus and care must be taken to minimise these with the avoidance of contrast agents. Teaching Points • Ultrasound and MRI are the preferred investigations for acute pelvic pain during pregnancy. • Ultrasound remains the primary imaging investigation because of availability and portability. • MRI helps differentiate causes of acute pelvic pain when ultrasound is inconclusive.

    A 67-year-old male known to be hypertensive and diabetic had a sudden onset of severe low back pain and flaccid paraplegia with no sensory level or bladder affection and the distal pulsations were felt. Acute compressive myelopathy was excluded by MRI of the dorsal and lumbar spines. The nerve conduction study and CSF analysis was suggestive of acute demyelinating polyneuropathy. The patient developed ischemic changes of the lower limb and CT angiography revealed severe stenosis of the abdominal aorta and both common iliac arteries. We emphasize the importance of including acute aortic occlusion in the differential diagnosis of acute flaccid paraplegia especially in the presence of severe back pain even if the distal pulsations were felt.

    While acute heart failure (AHF) is often regarded as a single disorder, an evolving understanding recognises the existence of multiple phenotypes with varied pathophysiological alterations. Herein we discuss hypertensive AHF and provide insight into a mechanism where acute fluid redistribution is caused by a disturbance in the ventricular-vascular coupling relationship. In this relationship, acute alterations in vascular elasticity, vasoconstriction and reflected pulse waves lead to increases in cardiac work and contribute to decompensated LV function with associated subendocardial ischaemia and end-organ damage. Chronic predisposing factors (neurohormonal activity, nitric oxide insensitivity, arterial stiffening) and physiological stressors (sympathetic surge, volume overload, physical exertion) that are causally linked to acute symptom onset are discussed. Lastly, we review treatment options including both nitrovasodilators and promising novel therapeutics, and discuss future directions in the management of this phenotypic variant. PMID:26123135

    Ischemic stroke is a medical emergency and must be treated as quickly as possible according to the "time-is-brain" concept. At present, intravenous administration of recombinant tissue plasminogen activator (rt-PA) within the first 4.5 h from stroke onset is the only effective treatment but is currently still only approved within the first 3 h from onset of symptoms (0.9 mg/kg body weight, maximum dose 90 mg, 10% of the cumulative dose as bolus, remaining 90% subsequently infused within 60 min). The therapeutic effect of magnetic resonance imaging (MRI) based thrombolytic therapy beyond the 4.5 h time window remains to be proven. Proximal occlusions of the middle cerebral artery can be treated successfully within the first 6 h from stroke onset by catheter-based intra-arterial administration of plasminogen activator leading to a significant improvement of outcome. Acute basilar artery occlusion should be treated in specialized centres using intra-arterial application of urokinase, rt-PA or mechanical recanalization but intravenous thrombolysis beyond the 3 h window is an acceptable alternative.

  17. The Coagulopathy of Acute Sepsis

    Simmons, Jeff; Pittet, Jean-Francois

    2015-01-01

    Purpose of Review Sepsis, defined by the presence of infection and host inflammation, is a lethal clinical syndrome with an increasing mortality rate worldwide. In severe disease, the coagulation system becomes diffusely activated, with consumption of multiple clotting factors resulting in Disseminated Intravascular Coagulation (DIC). When present, DIC portends a higher mortality rate. Understanding the mechanisms that tie inflammation and diffuse thrombosis will allow therapeutic interventions to be developed. The Coagulopathy of Acute Sepsis is a dynamic process that is time and disease burden specific. Whole blood testing of coagulation may provide more clinically useful information than classical tests. Natural anticoagulants that regulate thrombosis are down regulated in sepsis. Patients may benefit from modulation of the coagulation system when systemic inflammation and hypercoagulopathy exist. Proper timing of anticoagulant therapy may ultimately lead to decreased incidence of multisystem organ dysfunction (MODS). Recent Findings The pathogenesis of coagulopathy in sepsis is driven by an up-regulation of procoagulant mechanisms and simultaneous down-regulation of natural anticoagulants. Inflammation caused by the invading organism is a natural host defense than cannot be eliminated during treatment. Successful strategies to prevent MODS center on stratifying patients at high risk for DIC and restoring the balance of inflammation and coagulation. Summary The prevention of DIC in septic patients is a key therapeutic target in preventing death from multisystem organ failure. Stratifying patients for therapy using thromboelastometry, specific markers for DIC, and composite scoring systems is an area of growing research. PMID:25590467

    2015-01-01

    Acute liver failure (ALF) is a rare, potentially fatal complication of severe hepatic illness resulting from various causes. In a clinical setting, severe hepatic injury is usually recognised by the appearance of jaundice, encephalopathy and coagulopathy. The central and most important clinical event in ALF is occurrence of hepatic encephalopathy (HE) and cerebral edema which is responsible for most of the fatalities in this serious clinical syndrome. The pathogenesis of encephalopathy and cerebral edema in ALF is unique and multifactorial. Ammonia plays a central role in the pathogenesis. The role of newer ammonia lowering agents is still evolving. Liver transplant is the only effective therapy that has been identified to be of promise in those with poor prognostic factors, whereas in the others, aggressive intensive medical management has been documented to salvage a substantial proportion of patients. A small fraction of patients undergo liver transplant and the remaining are usually treated with medical therapy. Therefore, identification of the complications and causes of death in such patients, and use of appropriate prognostic models to identify those who need liver transplant and those who can be managed with medical treatment is a vital component of therapeutic strategy. In this review, we discuss the various pathogenetic mechanisms and treatment options available. PMID:26041950

    PubMed Central

    Basile, David P.; Anderson, Melissa D.; Sutton, Timothy A.

    2014-01-01

    Acute kidney injury (AKI) is the leading cause of nephrology consultation and is associated with high mortality rates. The primary causes of AKI include ischemia, hypoxia or nephrotoxicity. An underlying feature is a rapid decline in GFR usually associated with decreases in renal blood flow. Inflammation represents an important additional component of AKI leading to the extension phase of injury, which may be associated with insensitivity to vasodilator therapy. It is suggested that targeting the extension phase represents an area potential of treatment with the greatest possible impact. The underlying basis of renal injury appears to be impaired energetics of the highly metabolically active nephron segments (i.e., proximal tubules and thick ascending limb) in the renal outer medulla, which can trigger conversion from transient hypoxia to intrinsic renal failure. Injury to kidney cells can be lethal or sublethal. Sublethal injury represents an important component in AKI, as it may profoundly influence GFR and renal blood flow. The nature of the recovery response is mediated by the degree to which sublethal cells can restore normal function and promote regeneration. The successful recovery from AKI depends on the degree to which these repair processes ensue and these may be compromised in elderly or CKD patients. Recent data suggest that AKI represents a potential link to CKD in surviving patients. Finally, earlier diagnosis of AKI represents an important area in treating patients with AKI that has spawned increased awareness of the potential that biomarkers of AKI may play in the future.

    The toxicity, toxicokinetics, and progressive pathological changes produced by sodium selenite in sheep following parenteral administration were evaluated. In the intramuscular study, the LD/sub 50/ for sodium selenite was 0.7 mg selenium/kg body weight. In the continuous intravenous infusion study, a gradient of tissue selenium/kg body weight with a standard error of 0.035 over a 192 hour observation period. The most evident clinical signs were dyspnea and depression . At necropsy, the most consistent lesions were edematous lungs and pale mottled hearts. Highest tissue selenium concentrations in declining order were found in the liver, kidney, and heart. Four sheep injected intravenously with 0.7 mg selenium/kg body weight survived the 192 hour post-injection observation period. Semilogarithmic plots of blood selenium concentration versus time were triphasic. The ..cap alpha.. and ..gamma.. rate constants of sheep administered a single dose of selenium intravenously were significantly greater than those obtained when sheep were injected intramuscularly with 0.7 mg selenium concentrations was attained with 4, 8, and 12 hour infusions at steady state concentrations of 2500, 3000, and 3500 ppb selenium in the blood. The heart was the target organ of acute selenium toxicosis. A dose-response relationship was observed in the heart with degeneration evident in all hearts and necrosis present in the 2 hearts with the highest concentrations of selenium.

    1994-06-01

    Following a brief introduction regarding the epidemiology of diverticular disease, the authors report a rare case of diverticulitis of the cecum which had developed into an abscess. The patient was a 37-year-old man who was referred to the authors' attention with classic symptoms of acute appendicitis and it was therefore decided to operate. During laparotomy a small paracecal abscess involving a diverticulum with suppurating infection was found on the anterior wall of the cecum, whereas the appendix appeared to be completely unaffected. The diverticulum was removed together with a small area of the surrounding healthy tissue using a double-layer suture of the cecal wall. In the discussion the authors analyse the similarities and rarities of the case and compare it with national and international findings. Special attention is drawn to the problems of differential diagnosis raised by this rare pathology. In conclusion, the authors state that it is difficult to make a preoperative diagnosis and that therefore the decision to operate must be extemporary. PMID:7970067

    A total of 773 admissions to Massachusetts General Hospital between 1962 and 1975 were due to acute overdosage with one or more psychotropic drugs. Benzodiazepine overdosage, particularly with diazepam, increased relative to other psychotropic drugs over the years. Only 12 admissions were due to benzodiazepine overdosage alone, and none of these patients were seriously ill or had significant complications. Multiple drugs were ingested in the other 87 cases, and the frequency and severity of complications among these individuals depended upon the type and quantity of other nonbenzodiazepines taken. For example, 21 of 31 patients who ingested benzodiazepines together with barbiturates experienced severe central nervous system (CNS) depression, and 14 of 31 required assisted ventilation. However, the frequency of such complications was nearly identical in a group of patients who ingested barbiturates alone. This report and a review of the literature suggest that serious intoxication following overdosage with a benzodiazepine derivative alone is unusual. Ingestion of benzodiazepines together with other drugs appears to be considerably more common than benzodiazepine overdosage alone as a cause of intoxication. The severity of intoxication in such cases of multiple drug ingestion probably depends largely on the type and quantity of nonbenzodiazepines. PMID:14802

    Two patients with anorexia nervosa were treated on a general surgical unit for acute gastric dilatation. In both cases the dilatation rapidly followed an increase in the usual low dietary intake of the patients, and the ingestion of extra food may have initiated the acute episode.

    Eleven patients with suspected acute cholecystitis underwent sequential {sup 99}mTc-iminodiacetic derivative (IDA) and {sup 111}In-white blood cell (WBC) imaging to determine if {sup 111}In-WBCs accumulate within an acutely inflamed hemorrhagic gallbladder wall and, thus, could be employed as a reasonable alternative to {sup 99}mTc-IDA scintigraphy in detecting acute cholecystitis. Seven patients had surgically confirmed acute cholecystitis. Of these cases, five had a true-positive {sup 99}mTc-IDA and {sup 111}In-WBC, one an indeterminate {sup 111}In-WBC and true-positive {sup 99}mTc-IDA, and one a true-positive {sup 111}In-WBC and false-negative {sup 99}mTc-IDA scan. The remaining four patients did not have acute cholecystitis. All visualized their gallbladder within 1 hr after {sup 99}mTc-IDA administration and none had {sup 111}In-WBC gallbladder wall uptake. Both {sup 111}In-WBC and {sup 99}mTc-IDA scintigraphy accurately detected acute cholecystitis: hepatobiliary scintigraphy demonstrated a cystic duct obstruction and {sup 111}In-WBC imaging detected the inflammatory infiltrate within the gallbladder wall. The sensitivity and specificity of each was 86% and 100%, respectively.

METHODS Retrospective study on 100 patients who presented to the ophthalmic plastic clinic of a tertiary eye care center from May 2011 and April 2013 with acute and chronic dacryocystitis was reviewed for demographic and microbiological profile. The culture results and organisms isolated were recorded. RESULTS Sixty patients had acute onset and the remaining 40 patients had chronic onset dacryocystitis. The female to male ratio was 1.78. The mean age of patients was 44y. Gram-positive organisms were the most commonly isolated accounting for 54%, and the commonest species isolated was S. aureus in 26%. Percentage of gram positive cultures was higher in chronic dacryocystitis than acute ones (82% vs 48% of positive cultures; P=0.003). Also in culture positive acute dacryocystitis, gram negative species were found in 52% of eyes but only in 18% of chronic dacryocystitis. CONCLUSION Gram negative bacteria, culture negative samples, unusual and more virulent organisms are more common in acute dacryocystitis than chronic ones. The results of this study have significant bearing on the treatment of patients with dacrocystitis. PMID:25349808

    Acute pulmonary oedema in pregnant women is an uncommon but life-threatening event. The aims of this review are to address why pulmonary oedema occurs in pregnant women and to discuss immediate management. We performed a systematic literature search of electronic databases including MEDLINE, EMBASE and the Cochrane Library, using the key words obstetrics, pregnancy, acute pulmonary oedema, pregnancy complications, maternal, cardiac function and haemodynamics. We present a simple clinical classification of acute pulmonary oedema in pregnancy into pulmonary oedema occurring in normotensive or hypotensive women (i.e. without hypertension), and acute pulmonary oedema occurring in hypertensive women, which allows focused management. Pre-eclampsia remains an important cause of hypertensive acute pulmonary oedema in pregnancy and preventive strategies include close clinical monitoring and restricted fluid administration. Immediate management of acute pulmonary oedema includes oxygenation, ventilation and circulation control with venodilators. Pregnancy-specific issues include consideration of the physiological changes of pregnancy, the risk of aspiration and difficult airway, reduced respiratory and metabolic reserve, avoidance of aortocaval compression and delivery of the fetus.

    Acute pulmonary embolism (PE) is a frequent life-threatening condition in emergency departments. Careful diagnosis is important, and different diagnostic tests such as electrocardiogram (ECG), biochemical markers, echocardiogram, and computed tomography are required. Although ECG is a cheap and rapid diagnostic test for pulmonary embolism, it has some limitations in the differential diagnosis of acute coronary syndrome and acute PE. Herein, we report ECG results of a patient diagnosed with acute PE mimicking acute coronary syndrome. PMID:27092202

  13. Acute cough: a diagnostic and therapeutic challenge

    PubMed Central

    2009-01-01

    Background Acute cough is one of the most common complaints prompting patient visits to healthcare professionals. Despite the broad repercussions of acute cough on patient quality of life, school and work productivity, and public health resources, research on this condition is minimal, as are the available treatment options. Many patients use over-the-counter medicines, which are often ineffective for symptom relief. Some therapies may achieve antitussive activity, but at the expense of unpleasant or intolerable side effects. Unmet needs When considering the treatments currently available for the management of acute cough, the multiple limitations of such treatments are quite apparent. Most of these treatments lack clinically proven efficacy and reliability to support their use. This reinforces the need for the generation of quality scientific data from well-performed clinical trials. Hopefully, the result will be the development of safer, more effective and more reliable therapeutic options in the management of acute cough. Cough assessment and management Acute cough can be due to a variety of causes, and it is worthwhile to consider these pathogenic factors in some detail. It is also important to be familiar with the effects that acute cough has on patients' quality of life, work productivity, and the healthcare system; proper awareness of these effects may contribute to better understanding of the social impact of cough. In reference to the available treatments for the management of acute cough, adequate knowledge of the type of over-the-counter and prescription products in the market, as well as their mode of action and advantages/disadvantages, may provide expanded pharmacotherapeutic opportunities and facilitate better clinical decisions. However, due to the drawbacks of current treatment options, ideas for future cough management and newer products need to be considered and tested. Conclusion In view of the socio-economic impact of acute cough and the

    Inflammatory bowel diseases (IBD), such as ulcerative colitis and Crohn's disease, are an important cause of morbidity and impact significantly on quality of life. Overall, current treatments do not sustain a long-term clinical remission and are associated with adverse effects, which highlight the need for new treatment options. Fucoidans are complex sulphated, fucose-rich polysaccharides, found in edible brown algae and are described as having multiple bioactivities including potent anti-inflammatory effects. Therefore, the therapeutic potential of two different fucoidan preparations, fucoidan-polyphenol complex (Maritech Synergy) and depyrogenated fucoidan (DPF) was evaluated in the dextran sulphate sodium (DSS) mouse model of acute colitis. Mice were treated once daily over 7 days with fucoidans via oral (Synergy or DPF) or intraperitoneal administration (DPF). Signs and severity of colitis were monitored daily before colons and spleens were collected for macroscopic evaluation, cytokine measurements and histology. Orally administered Synergy and DPF, but not intraperitoneal DPF treatment, significantly ameliorated symptoms of colitis based on retention of body weight, as well as reduced diarrhoea and faecal blood loss, compared to the untreated colitis group. Colon and spleen weight in mice treated with oral fucoidan was also significantly lower, indicating reduced inflammation and oedema. Histological examination of untreated colitis mice confirmed a massive loss of crypt architecture and goblet cells, infiltration of immune cells and oedema, while all aspects of this pathology were alleviated by oral fucoidan. Importantly, in this model, the macroscopic changes induced by oral fucoidan correlated significantly with substantially decreased production of at least 15 pro-inflammatory cytokines by the colon tissue. Overall, oral fucoidan preparations significantly reduce the inflammatory pathology associated with DSS-induced colitis and could therefore represent

    Severe acute respiratory syndrome (SARS) is a viral disease, observed primarily in Southern China in November 2002, with variable flu-like symptoms and pneumonia, in approx. 5% leading to death from respiratory distress syndrome (RDS). The disease was spread over more than 30 states all over the globe by SARS-virus-infected travelers. WHO and CDC received first information about a new syndrome by the end of February 2003, after the first cases outside the Republic of China had been observed. A case in Hanoi, Vietnam, led to the first precise information about the new disease entity to WHO, by Dr. Carlo Urbani, a co-worker of WHO/Doctors without Borders, who had been called by local colleagues to assist in the management of a patient with an unknown severe disease by the end of February 2003. Dr. Urbani died from SARS, as did many other health care workers. In the meantime, more than 7,000 cases have been observed worldwide, predominantly in China and Hong Kong, but also in Taiwan, Canada, Singapore, and the USA, and many other countries, and more than 600 of these patients died from RDS. Since the beginning of March 2003, when WHO and CDC started their activities, in close collaboration with a group of international experts, including the Bernhard-Nocht-Institute in Hamburg and the Department of Virology in Frankfurt/Main, a previously impossible success in the disclosure of the disease was achieved. Within only 8 weeks of research it was possible to describe the infectious agent, a genetically modified coronavirus, including the genetic sequence, to establish specific diagnostic PCR methods and to find possible mechanisms for promising therapeutic approaches. In addition, intensifying classical quarantine and hospital hygiene measures, it was possible to limit SARS in many countries to sporadic cases, and to reduce the disease in countries such as Canada and Vietnam.

    Tiemstra, Jeffrey D

    2012-06-15

    Ankle sprains are a common problem seen by primary care physicians, especially among teenagers and young adults. Most ankle sprains are inversion injuries to the lateral ankle ligaments, although high sprains representing damage to the tibiofibular syndesmosis are becoming increasingly recognized. Physicians should apply the Ottawa ankle rules to determine whether radiography is needed. According to the Ottawa criteria, radiography is indicated if there is pain in the malleolar or midfoot zone, and either bone tenderness over an area of potential fracture (i.e., lateral malleolus, medial malleolus, base of fifth metatarsal, or navicular bone) or an inability to bear weight for four steps immediately after the injury and in the emergency department or physician's office. Patients with ankle sprain should use cryotherapy for the first three to seven days to reduce pain and improve recovery time. Patients should wear a lace-up ankle support or an air stirrup brace combined with an elastic compression wrap to reduce swelling and pain, speed recovery, and protect the injured ligaments as they become more mobile. Early mobilization speeds healing and reduces pain more effectively than prolonged rest. Pain control options for patients with ankle sprain include nonsteroidal anti-inflammatory drugs, acetaminophen, and mild opioids. Because a previous ankle sprain is the greatest risk factor for an acute ankle sprain, recovering patients should be counseled on prevention strategies. Ankle braces and supports, ankle taping, a focused neuromuscular training program, and regular sport-specific warm-up exercises can protect against ankle injuries, and should be considered for patients returning to sports or other high-risk activities.

    Acute promyelocytic leukemia (APL) represents a medical emergency with a high rate of early mortality. As a consequence, as soon as the diagnosis is suspected based upon cytologic criteria, it is necessary to start all- trans retinoic acid (ATRA) treatment without delay. For patients with newly diagnosed APL, induction therapy with ATRA plus anthracycline based chemotherapy is recommended. At present the combination of arsenic trioxide plus ATRA should be considered for patients who are not candidates for anthracycline-based therapy. For pediatric and adult patients with APL aged < 60 years who achieve a CR with induction, I recommend 3 intensive courses of consolidation chemotherapy associated to ATRA, targeted on the basis of the risk group at diagnosis. In patients treated with a very intensive consolidation chemotherapy maintenance treatment can be omitted. However If a maintenance treatment has to be adopted I suggest the use of intermittent ATRA for 15 days every 3 months for a period of 2 years, rather than ATRA associated to chemotherapy. Moreover, taking into account the medical literature, a reduced dosage of ATRA ( 25 mg/m2) in pediatric patients and a consolidation chemotherapy of reduced intensity in elderly patients is recommended. Furthermore, in order to maximize survival, careful attention should be reserved to the coagulopathy and to the appearance of the differentiation syndrome. Finally, PCR for the PML/RARA fusion gene on a bone marrow specimen every three months for two years, and then every six months for additional three years are needed during the follow-up.

    The acute handling hazards of several alkylalkanolamines were determined by investigating their potential acute toxicity and primary irritancy. Materials studied were N-methylethanolamine (MEA), N, N, -dimethylethanolamine (DMEA), N, N, -dimethylisopropanolamine (DMIPA), N-methyldiethanolamine (MDEA), and tertbutyldiethanolamine (BDEA). All these alkylalkanolamines were of comparable acute peroral toxicity in the rat (LD50 range 1.48-2.83 ml/kg). By 24 h occluded epicutaneous contact in the rabbit, MEA, DMEA and DMIPA were of moderate acute percutaneous toxicity (LD50 range 1.13-2.0 ml/kg), MDEA was of slight acute percutaneous toxicity (LD50 male 9.85 ml/kg, female 10.90 ml/kg), and BDEA of intermediate toxicity (LD50 6.4 ml/kg). Due to differences in vapor pressure the acute vapor exposure toxicity of the alkylalkanolamines to rats varied; MEA, MDEA and BDEA were of a low order of acute toxicity, and DMIPA was moderately toxic with an LT50 of 3.2 h for a saturated vapor atmosphere exposure. A 4 h-LC50 (rat combined sex) of 1461 ppm was determined for DMEA. All alkylalkanolamines studied, except MDEA, were moderately to markedly irritating and caused variable degrees of skin corrosivity; MDEA caused only transient minor skin irritation. In accord with the skin irritancy results, the eye irritancy from 0.005 ml MEA, DMEA, DMIPA and BDEA was severe, and that from MDEA was slight. Exposure to these compounds has implications for occupational health procedures. PMID:8948072

    The unique characteristics of pulmonary circulation and alveolar-epithelial capillary-endothelial barrier allow for maintenance of the air-filled, fluid-free status of the alveoli essential for facilitating gas exchange, maintaining alveolar stability, and defending the lung against inhaled pathogens. The hallmark of pathophysiology in acute respiratory distress syndrome is the loss of the alveolar capillary permeability barrier and the presence of protein-rich edema fluid in the alveoli. This alteration in permeability and accumulation of fluid in the alveoli accompanies damage to the lung epithelium and vascular endothelium along with dysregulated inflammation and inappropriate activity of leukocytes and platelets. In addition, there is uncontrolled activation of coagulation along with suppression of fibrinolysis and loss of surfactant. These pathophysiological changes result in the clinical manifestations of acute respiratory distress syndrome, which include hypoxemia, radiographic opacities, decreased functional residual capacity, increased physiologic deadspace, and decreased lung compliance. Resolution of acute respiratory distress syndrome involves the migration of cells to the site of injury and re-establishment of the epithelium and endothelium with or without the development of fibrosis. Most of the data related to acute respiratory distress syndrome, however, originate from studies in adults or in mature animals with very few studies performed in children or juvenile animals. The lack of studies in children is particularly problematic because the lungs and immune system are still developing during childhood and consequently the pathophysiology of pediatric acute respiratory distress syndrome may differ in significant ways from that seen in acute respiratory distress syndrome in adults. This article describes what is known of the pathophysiologic processes of pediatric acute respiratory distress syndrome as we know it today while also presenting the much

    A number of cases of acute myopericarditis mimicking acute myocardial infarction (AMI) have previously been reported in the literature. However, to the best of our knowledge, such a case resulting from Mycobacterium tuberculosis infection has not previously been described. The present study reports the case of a 21-year-old male patient presenting with acute chest pain, in whom focal ST-segment elevation and elevated cardiac enzymes mimicked a diagnosis of AMI. However, acute tuberculous myopericarditis was diagnosed on the basis of a variety of imaging examinations, laboratory tests, as well as the changes observed in electrocardiograms (ECGs) and in the cardiac enzyme levels. The case highlights the importance of a detailed collection of medical history, comprehensive explanations of serial ECGs, thoracic computed tomography, echocardiogram and coronary angiography in the diagnosis and differentiation of acute tuberculous myopericarditis mimicking AMI.

    Acute apical abscess is the most common form of dental abscess and is caused by infection of the root canal of the tooth. It is usually localized intraorally, but in some cases the apical abscess may spread and result in severe complications or even mortality. The reasons why dental root canal infections can become symptomatic and evolve to severe spreading and sometimes life-threatening abscesses remain elusive. Studies using culture and advanced molecular microbiology methods for microbial identification in apical abscesses have demonstrated a multispecies community conspicuously dominated by anaerobic bacteria. Species/phylotypes commonly found in these infections belong to the genera Fusobacterium, Parvimonas, Prevotella, Porphyromonas, Dialister, Streptococcus, and Treponema. Advances in DNA sequencing technologies and computational biology have substantially enhanced the knowledge of the microbiota associated with acute apical abscesses and shed some light on the etiopathogeny of this disease. Species richness and abundance and the resulting network of interactions among community members may affect the collective pathogenicity and contribute to the development of acute infections. Disease modifiers, including transient or permanent host-related factors, may also influence the development and severity of acute abscesses. This review focuses on the current evidence about the etiology and treatment of acute apical abscesses and how the process is influenced by host-related factors and proposes future directions in research, diagnosis, and therapeutic approaches to deal with this disease.

    Acute disseminated encephalomyelitis is a demyelinating disease, typically occurring in children following a febrile infection or a vaccination. Primary and secondary immune responses contribute to inflammation and subsequent demyelination, but the exact pathogenesis is still unknown. Diagnosis of acute disseminated encephalomyelitis is strongly suggested by temporal relationship between an infection or an immunization and the onset of neurological symptoms. Biopsy is definitive. In general, the disease is self-limiting and the prognostic outcome is favorable with anti-inflammatory and immunosuppressive agents. Locked-in syndrome describes patients who are awake and conscious but have no means of producing limb, speech, or facial movements. Locked-in syndrome is a rare complication of acute disseminated encephalomyelitis. We present a case of incomplete locked-in syndrome occurring in a 34-year-old male secondary to acute disseminated encephalomyelitis. Our case is unique, as acute disseminated encephalomyelitis occurred in a 34-year-old which was poorly responsive to immunosuppression resulting in severe disability. PMID:24977089

    Zygomycosis is a rare invasive opportunistic fungal infection that occurs in the setting of hematologic malignancies, chemotherapy-induced neutropenia, and immunosuppressive therapies. We report the first case of disseminated appendiceal zygomycosis due to Absidia spp. in a neutropenic patient who initially presented as acute appendicitis. A 63-year-old woman with acute myeloid leukemia presented as acute appendicitis while receiving induction chemotherapy and ultimately succumbed to overwhelming disseminated zygomycosis. Initial symptoms included loose stools and right lower abdominal pain unresponsive to broad-spectrum antibiotics. Clinical examination and cross-sectional imaging suggested acute appendicitis. The final diagnosis was established by histological evaluations of the ileocecectomy specimen, which showed angioinvasive fungal organisms within the necrotic appendiceal wall with characteristics typical of zygomycetes. Fungal cultures demonstrated Absidia spp. The patient was treated with amphotericin B but expired in the setting of fungal sepsis. A diagnosis of a fungal infection, including zygomycosis, should be considered in all chemotherapy-induced neutropenic patients who present with symptoms of acute appendicitis. A high index of clinical suspicion with prompt histologic and culture diagnosis of zygomycosis may reduce the high mortality and morbidity associated with zygomycosis of the gastrointestinal tract.

    Acute cardiovascular exercise effects on cognitive function were examined using an executive control task by comparing neuroelectric and behavioral performance at baseline with post-exercise in 20 undergraduates. A within-subjects design was used to assess the P3 component of an event-related brain potential (ERP) and behavioral performance using a task that varied the amount of executive control required. The baseline session involved participation on the Eriksen flankers task followed by a graded maximal exercise test to measure cardiovascular fitness. The exercise session consisted of a 30-min acute bout of exercise on a treadmill followed by the Eriksen flankers task after heart rate returned to within 10% of pre-exercise levels. Across midline recordings sites, results indicated larger P3 amplitude following acute exercise compared to baseline. Shorter P3 latency was observed during the baseline Eriksen flankers task for the neutral compared to the incompatible condition; an effect not found following the acute bout of exercise. These findings suggest that acute bouts of cardiovascular exercise affect neuroelectric processes underlying executive control through the increased allocation of neuroelectric resources and through changes in cognitive processing and stimulus classification speed.

    Acute leukemias are characterized by accumulation of immature cells (blasts) and reduced production of healthy hematopoietic elements. According to the lineage origin, two major leukemias can be distinguished: acute myeloid leukemia (AML) and acute lymphoid leukemia (ALL). Although the survival rate for pediatric ALL is close to 90%, half of the young adults with AML or ALL and approximately 90% of older patients with AML or ALL still die of their disease, raising the need for innovative therapeutic approaches. As almost all leukemic blasts express specific surface antigens, targeted immunotherapy appears to be particularly promising. However, published results of immunotherapy alone are generally modest. Radioimmunotherapy (RIT) brings additional therapeutic mechanisms using radiolabeled monoclonal antibodies (mAbs) directed to tumor antigens, thus adding radiobiological cytotoxicity to immunologic cytotoxicity. Because of the high radiosensitivity of tumor cells and the diffuse widespread nature of the disease, making it rapidly accessible to circulating radiolabeled mAbs, acute leukemias represent relevant indications for RIT. With the development of recombinant and humanized mAbs, innovative radionuclides, and more efficient radiolabeling and pretargeting techniques, RIT has significantly improved over the last 10 years. Different approaches of α and β RIT targeting CD22, CD33, CD45, or CD66 antigens have already been evaluated or are currently being developed in the treatment of acute leukemia. This review summarizes the preclinical and clinical studies demonstrating the potential of RIT in treatment of AML and ALL. PMID:26897718

    Background The aim of this article is to present the most recent suggestions for the therapy of acute cholangitis and cholecystitis based on a review of the current literature. Methods We performed a systematic literature search in the Medline, PubMed, and Google Scholar databases using the keywords mentioned above. This article is strongly influenced by the publication of the Tokyo Guidelines for the management of acute cholangitis and cholecystitis (TG07, TG13) in 2007 and 2013. These were the first practical guidelines targeting diagnosis and treatment of acute cholangitis and cholecystitis. These guidelines are based on the best published evidence and a consensus conference of international experts in the field. Results and Conclusion Acute cholangitis and acute cholecystitis are common conditions that may result in progressively severe infection and death when not treated appropriately. Beside supportive therapy and antiobstructive measures, therapy with antimicrobial agents is an important component in the management of affected patients. Here, we discuss the use of antimicrobial agents that are suitable for the first-line management of these infections. Empirical therapy depends upon the knowledge of local microbial epidemiology and patient-specific factors affecting the selection of appropriate agents. PMID:26535043

    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

There are many patients suffering from acute respiratory failure caused by nosocomial pneumonia, septic syndrome, aspiration, interstitial or alveolar lung edema, thromboembolism of a. pulmonalis, polytrauma and lung contusion, acute respiratory distress syndrome, long-term mechanical ventilation of the lungs, acute lung injury, status asthmaticus, rather massive transfusions of blood products, and lipid embolism in the intensive care unit. There are actually three processes involved: the transfer of oxygen across the alveolus, the transport to the tissues (by cardiac output), and the removal of carbon dioxide from blood into the alveolus with subsequent exhalation into the environment. Failure of any step in this process can lead to respiratory failure. Long-term hypoxia causes ischemic changes and dysfunction of brain, heart, kidney, lungs and can worsen the course of disease or cause higher mortality. It is important to determine the pathogenetic mechanisms of acute respiratory failure, estimate the main parameters and their interrelations and prescribe proper treatment. PMID:15064552

  12. Management of acute upside-down stomach

    PubMed Central

    2013-01-01

    Background Upside-down stomach (UDS) is characterized by herniation of the entire stomach or most gastric portions into the posterior mediastinum. Symptoms may vary heavily as they are related to reflux and mechanically impaired gastric emptying. UDS is associated with a risk of incarceration and volvulus development which both might be complicated by acute gastric outlet obstruction, advanced ischemia, gastric bleeding and perforation. Case presentation A 32-year-old male presented with acute intolerant epigastralgia and anterior chest pain associated with acute onset of nausea and vomiting. He reported on a previous surgical intervention due to a hiatal hernia. Chest radiography and computer tomography showed an incarcerated UDS. After immediate esophago-gastroscopy, urgent laparoscopic reduction, repair with a 360° floppy Nissen fundoplication and insertion of a gradually absorbable GORE® BIO-A®-mesh was performed. Conclusion Given the high risk of life-threatening complications of an incarcerated UDS as ischemia, gastric perforation or severe bleeding, emergent surgery is indicated. In stable patients with acute presentation of large paraesophageal hernia or UDS exhibiting acute mechanical gastric outlet obstruction, after esophago-gastroscopy laparoscopic reduction and hernia repair followed by an anti-reflux procedure is suggested. However, in cases of unstable patients open repair is the surgical method of choice. Here, we present an exceptionally challenging case of a young patient with a giant recurrent hiatal hernia becoming clinically manifest in an incarcerated UDS. PMID:24228771

    Asthma is a prevalent chronic disease of the respiratory system and acute asthma exacerbations are among the most common causes of presentation to the emergency department (ED) and admission to hospital particularly in children. Bronchial airways inflammation is the most prominent pathological feature of asthma. Inhaled corticosteroids (ICS), through their anti-inflammatory effects have been the mainstay of treatment of asthma for many years. Systemic and ICS are also used in the treatment of acute asthma exacerbations. Several international asthma management guidelines recommend the use of systemic corticosteroids in the management of moderate to severe acute asthma early upon presentation to the ED. On the other hand, ICS use in the management acute asthma has been studied in different contexts with encouraging results in some and negative in others. This review sheds some light on the role of systemic and ICS in the management of acute asthma and discusses the current evidence behind their different ways of application particularly in relation to new developments in the field.

  14. Acute Bacterial Prostatitis: Diagnosis and Management.

    PubMed

    Coker, Timothy J; Dierfeldt, Daniel M

    2016-01-15

    Acute bacterial prostatitis is an acute infection of the prostate gland that causes pelvic pain and urinary tract symptoms, such as dysuria, urinary frequency, and urinary retention, and may lead to systemic symptoms, such as fevers, chills, nausea, emesis, and malaise. Although the true incidence is unknown, acute bacterial prostatitis is estimated to comprise approximately 10% of all cases of prostatitis. Most acute bacterial prostatitis infections are community acquired, but some occur after transurethral manipulation procedures, such as urethral catheterization and cystoscopy, or after transrectal prostate biopsy. The physical examination should include abdominal, genital, and digital rectal examination to assess for a tender, enlarged, or boggy prostate. Diagnosis is predominantly made based on history and physical examination, but may be aided by urinalysis. Urine cultures should be obtained in all patients who are suspected of having acute bacterial prostatitis to determine the responsible bacteria and its antibiotic sensitivity pattern. Additional laboratory studies can be obtained based on risk factors and severity of illness. Radiography is typically unnecessary. Most patients can be treated as outpatients with oral antibiotics and supportive measures. Hospitalization and broad-spectrum intravenous antibiotics should be considered in patients who are systemically ill, unable to voluntarily urinate, unable to tolerate oral intake, or have risk factors for antibiotic resistance. Typical antibiotic regimens include ceftriaxone and doxycycline, ciprofloxacin, and piperacillin/tazobactam. The risk of nosocomial bacterial prostatitis can be reduced by using antibiotics, such as ciprofloxacin, before transrectal prostate biopsy. PMID:26926407

    A better understanding of coronary syndromes allow physicians to appreciate UAP and AMI as part of a continuum of ACI. ACI is a life-threatening condition whose identification can have major economic and therapeutic importance as far as threatening dysrhythmias and preventing or limiting myocardial infarction size. The identification of ACI continues to challenge the skill of even experienced clinicians, yet physicians continue (appropriately) to admit the overwhelming majority of patients with ACI; in the process, they admit many patients without acute ischemia [2], overestimating the likelihood of ischemia in low-risk patients because of magnified concern for this diagnosis for prognostic and therapeutic reasons. Studies of admitting practices from a decade ago have yielded useful clinical information but have shown that neither clinical symptoms nor the ECG could reliably distinguish most patients with ACI from those with other conditions. Most studies have evaluated the accuracy of various technologies for diagnosing ACI, yet only a few have evaluated the clinical impact of routine use. The prehospital 12-lead ECG has moderate sensitivity and specificity for the diagnosis of ACI. It has demonstrated a reduction of the mean time to thrombolysis by 33 minutes and short-term overall mortality in randomized trials. In the general ED setting, only the ACI-TIPI has demonstrated, in a large-scale multicenter clinical trial, a reduction in unnecessary hospitalizations without decreasing the rate of appropriate admission for patients with ACI. The Goldman chest pain protocol has good sensitivity for AMI but was not shown to result in any differences in hospitalization rate, length of stay, or estimated costs in the single clinical impact study performed. The protocol's applicability to patients with UAP has not been evaluated. Single measurement of biomarkers at presentation to the ED has poor sensitivity for AMI, although most biomarkers have high specificity. Serial

    Recently it has been suggested that cholescintigraphy is unreliable in the detection of acute cholecystitis when acute pancreatitis is present. During a recent 17 month interval, twenty-one patients with a firmly established diagnosis of acute pancreatitis underwent cholescintigraphy in our laboratory. The gallbladder failed to visualize in only five cases, all of whom had acute cholecystitis. These data, and those available in the literature, lead us to conclude that cholescintigraphy is useful in the diagnosis of acute cholecystitis whether or not acute pancreatitis is present.

    1975-01-01

    Two boys with Down's syndrome, recognized at birth, developed acute myelogibrosis at the ages of 19 and 21 months. The disorder presented with anaemia and splenomegaly, and clinically resembled acute leukaemia, but bone marrow histology showed a bizarre pattern with generalized fibrosis, markedly increased reticulin, large reticulum cells, and giant cells resembling megakaryocytes. The children survived 6 and 11 months from diagnosis. A third case is quoted (Hillman and Forrester, 1968) which was also studied at this hospital; the features of all 3 cases are similar. There appears to be an increased incidence of acute myelofibrosis in children with Down's syndrome, which may be a further example of the instability of the haemopoietic system in the disease. In children with Down's syndrome and unusual leukaemia-like illness, histological examination of the bone marrow may be diagnostic. Images FIG. 1. FIG. 2. FIG.3. PMID:125073

    This study develops data on the acute aquatic toxicity of selected biodiesel fuels which may become subject to environmental effects test regulations under the US Toxic Substances Control Act (TSCA). The test substances are Rape Methyl Ester (RME), Rape Ethyl Ester (REE), Methyl Soyate (MS), a biodiesel mixture of 20% REE and 80% Diesel, a biodiesel mixture of 50% REE and diesel, and a reference substance of Phillips D-2 Reference Diesel. The test procedure follows the Daphnid Acute Toxicity Test outlined in 40 CFR {section} 797.1300 of the TSCA regulations. Daphnia Magna are exposed to the test substance in a flow-through system consisting of a mixing chamber, a proportional diluter, and duplicate test chambers. Novel system modifications are described that accommodate the testing of oil-based test substances with Daphnia. The acute aquatic toxicity is estimated by an EC50, an effective concentration producing immobility in 50% of the test specimen.

    Terrorist use of organophosphorus-based nerve agents and toxic industrial chemicals against civilian populations constitutes a real threat, as demonstrated by the terrorist attacks in Japan in the 1990 s or, even more recently, in the Syrian civil war. Thus, development of more effective countermeasures against acute organophosphorus poisoning is urgently needed. Here, we have generated and validated zebrafish models for mild, moderate and severe acute organophosphorus poisoning by exposing zebrafish larvae to different concentrations of the prototypic organophosphorus compound chlorpyrifos-oxon. Our results show that zebrafish models mimic most of the pathophysiological mechanisms behind this toxidrome in humans, including acetylcholinesterase inhibition, N-methyl-D-aspartate receptor activation, and calcium dysregulation as well as inflammatory and immune responses. The suitability of the zebrafish larvae to in vivo high-throughput screenings of small molecule libraries makes these models a valuable tool for identifying new drugs for multifunctional drug therapy against acute organophosphorus poisoning.

    Acute inflammation in the lung is essential to health. So too is its resolution. In response to invading microbes, noxious stimuli or tissue injury, an acute inflammatory response is mounted to protect the host. To limit inflammation and prevent collateral injury of healthy, uninvolved tissue, the lung orchestrates the formation of specialized pro-resolving mediators, specifically lipoxins, resolvins, protectins and maresins. These immunoresolvents are agonists for resolution that interact with specific receptors on leukocytes and structural cells to blunt further inflammation and promote catabasis. This process appears to be defective in several common lung diseases that are characterized by excess or chronic inflammation. Here, we review the molecular and cellular effectors of resolution of acute inflammation in the lung. PMID:24313723

    In the management of acute severe asthma it is very important to start the treatment as soon as possible, by appropriate evaluation of the physical status and signs of airflow obstruction. We propose a guideline to be used by patients with asthma, emergency car crews, physicians and nurses to evaluate the severity and to choose the appropriate management of acute asthma, including intubation and mechanical ventilation, by the assessment of clinical features, as well as blood gas analysis and pulmonary function test. Several researchers have demonstrated that the additional administration of aminophylline to inhaled or subcutaneous beta 2-agonist bronchodilator during the first 4 hours of an attack provides no additional benefit compared to the administration of beta 2-agonist alone. In our retrospective study of 68 episodes of acute severe asthma in the last 5 years at our institute, however, the additional administration of aminophylline with beta 2-agonists was clearly shown to be effective with infrequent minor side effects.

    Background Physicians treating acute pulmonary embolism (PE) are faced with difficult management decisions while specific guidance from recent guidelines may be absent. Methods Fourteen clinical dilemmas were identified by physicians and haematologists with specific interests in acute and chronic PE. Current evidence was reviewed and a practical approach suggested. Results Management dilemmas discussed include: sub-massive PE, PE following recent stroke or surgery, thrombolysis dosing and use in cardiac arrest, surgical or catheter-based therapy, failure to respond to initial thrombolysis, PE in pregnancy, right atrial thrombus, role of caval filter insertion, incidental and sub-segmental PE, differentiating acute from chronic PE, early discharge and novel oral anticoagulants. Conclusion The suggested approaches are based on a review of the available evidence and guidelines and on our clinical experience. Management in an individual patient requires clinical assessment of risks and benefits and also depends on local availability of therapeutic interventions. PMID:24343784

    Although dipeptidyl peptidase-4 (DPP-4) inhibitors have been implicated in the development of acute pancreatitis, the causality of this phenomenon is not well established. We herein report the case of an 85-year-old woman who presented with epigastric pain after taking saxagliptin for five months. A high serum lipase level with characteristic computed tomography findings confirmed the diagnosis of acute pancreatitis. The patient's symptoms rapidly resolved after admission, although they recurred when she resumed treatment with saxagliptin for 18 days after discharge. In the absence of any identifiable causes of pancreatitis and considering the temporal sequence of events, the saxagliptin therapy was highly suspected to be the triggering factor. Although drug-induced pancreatitis is rare, treatment with DPP-4 inhibitors should be included as a potential etiology of acute pancreatitis. PMID:24930656

    Acute aortic dissection occurring during pregnancy represents a lethal risk to both the mother and fetus. Management of parturient with acute aortic dissection is complex. We report our experience of two pregnancies with type A acute aortic dissection. One patient is a 31-year-old pregnant woman (33rd gestational week) with a bicuspid aortic valve and the other is a 32-year-old pregnant woman (30th gestational week) with the Marfan syndrome. In both cases, a combined emergency operation consisting of Cesarean section, total hysterectomy prior to corrective surgery for aortic dissection was successfully performed within a relatively short period of time after the onset. Both patients' postoperative recovery was uneventful, and we achieved a favorable maternal and fetal outcome. PMID:25085319

    Context: Novel psychoactive substances, including synthetic cannabinoids, are becoming increasingly popular, with more patients being seen in the emergency room following acute ingestion. These substances have been associated with a wide range of adverse effects. However, identification of complications, clinical toxicity, and management remain challenging. Case Report: We present the case of a young African-American male who developed severe agitation and bizarre behavior following acute K2 ingestion. Laboratory studies revealed markedly elevated serum creatine phosphokinase (CPK) with normal renal function. The patient was managed with aggressive intravenous (IV) fluid hydration and treatment of underlying psychiatric illness. Conclusion: We recommend the routine evaluation of renal function and CPK levels with early initiation of IV hydration among patients who present to the emergency department following acute ingestion of synthetic cannabinoids to identify potential complications early as well as institute early supportive therapy.

    Although corticosteroids have immunosuppressive, anti-inflammatory, and anti-allergic effects, allergic reactions are rare. We report a case involving a 52-year-old-female with acute urticaria caused by oral methylprednisolone. The patient had experienced aspirin-exacerbated respiratory disease (AERD) for 13 years with frequent asthma exacerbations. Symptoms of asthma exacerbations improved with short-term treatments of systemic steroids, including methylprednisolone or deflazacort, which had been well tolerated. However, the current admission was prompted by the development of acute generalized urticaria following the oral ingestion of methylprednisolone (8 mg) for relief of symptoms. An oral provocation test with 4 mg oral methylprednisolone led to generalized urticaria 20 minutes later, confirming the causal association. This is the first report of acute urticaria caused by oral methylprednisolone in a patient with AERD. PMID:21966609

    The acute toxicity of gasoline; its components benzene, toluene, and xylene; and the additives ethanol, methanol, and methyl tertiary butyl ether are reviewed. All of these chemicals are only moderately to mildly toxic at acute doses. Because of their volatility, these compounds are not extensively absorbed dermally unless the exposed skin is occluded. Absorption through the lungs and the gastrointestinal tract is quite efficient. After ingestion, the principal danger for a number of these chemicals, particularly gasoline, is aspiration pneumonia, which occurs mainly in children. It is currently not clear whether aspiration pneumonia would still be a problem if gasoline were diluted with ethanol or methanol. During the normal use of gasoline or mixtures of gasoline and the other solvents as a fuel, exposures would be much lower than the doses that have resulted in poisoning. No acute toxic health effects would occur during the normal course of using automotive fuels. 128 refs., 7 tabs.

    To evaluate the effect of graft irradiation in the treatment of acute rejection of renal transplants, a randomized study was conducted from 1978 to 1981. Patients with acute rejection were given standard medical management in the form of intravenous methylprednisolone, and were chosen randomly to receive either graft irradiation (175 rads every other day, to a total of 525 rads) or simulated (sham) irradiation. Eighty-three rejections occurring in 64 grafts were randomized to the protocol. Rejection reversal was recorded in 84.5% of control grafts and 75% of the irradiated grafts. Recurrent rejections were more frequent and graft survival was significantly lower in the irradiated group (22%) than in the control group (54%). Graft irradiation does not appear to be beneficial in the treatment of acute rejection of renal transplants when used in conjunction with high-dose steroids.

    Acute pulmonary embolism is a frequent cause of hospitalization and is associated with a wide range of symptom severity. Anticoagulants are the mainstay of treatment for acute pulmonary embolism; however, in patients with massive or submassive pulmonary embolism, advanced therapy with thrombolytics may be considered. The decision to use thrombolytic therapy for acute pulmonary embolism should be based on careful risk-benefit analysis for each patient, including risk of morbidity and mortality associated with the embolism and risk of bleeding associated with the thrombolytic. Alteplase is currently the thrombolytic agent most studied and with the most clinical experience for this indication, although the most appropriate dose remains controversial, especially in patients with low body weight. When considering thrombolysis, unfractionated heparin is the preferred initial anticoagulant due to its short duration of action and its reversibility should bleeding occur. PMID:25559613

    An otherwise healthy young man was transferred to our hospital after a diving incident. He had made an uncontrolled ascent from 10 m. On arrival he appeared well. No hypotensive episodes occurred during the transfer. He denied having arthralgias, back pain, dyspnoea or neurological symptoms. Laboratory investigations revealed acutely elevated creatinine (170 µmol/L) and creatine kinase (909 U/L). Radiology was consistent with a focus of pulmonary barotrauma and intrinsic renal disease. Creatine kinase is a marker of arterial gas embolism (AGE). We determined that our patient suffered acute kidney injury as a result of gas embolisation to his renal vasculature from an area of pulmonary barotrauma. Creatinine fell the following day in response to aggressive intravenous fluids. This is the first reported case of acute kidney injury secondary to AGE. Biochemical studies should be part of the routine assessment of patients involved in diving incidents. PMID:25948841

    The acutely obstructed airway is a medical emergency that can potentially result in serious morbidity and mortality. Apart from the latest advancements in anaesthetic techniques, equipment and drugs, publications relevant to our topic, including the United Kingdom’s 4th National Audit Project on major airway complications in 2011 and the updated American Society of Anesthesiologists’ difficult airway algorithm of 2013, have recently been published. The former contained many reports of adverse events associated with the management of acute airway obstruction. By analysing the data and concepts from these two publications, this review article provides an update on management techniques for the acutely obstructed airway. We discuss the principles and factors relevant to the decision-making process in formulating a logical management plan. PMID:26996162

    Unlike chronic heart failure (HF), the treatment for acute HF has not changed over the last decade. The drugs employed have shown their ability to control symptoms but have not achieved organ protection or managed to reduce medium to long-term morbidity and mortality. Advances in our understanding of the pathophysiology of acute HF suggest that treatment should be directed not only towards correcting the haemodynamic disorders and achieving symptomatic relief but also towards preventing organ damage, thereby counteracting myocardial remodelling and cardiac and extracardiac disorders. Compounds that exert vasodilatory and anti-inflammatory action in the acute phase of HF and can stop cell death, thereby boosting repair mechanisms, could have an essential role in organ protection.

    Severe acute pancreatitis poses unique nutritional challenges. The optimal nutritional support in patients with severe acute pancreatitis has been a subject of debate for decades. This review provides a critical review of the available literature. According to current literature, enteral nutrition is superior to parenteral nutrition, although several limitations should be taken into account. The optimal route of enteral nutrition remains unclear, but normal or nasogastric tube feeding seems safe when tolerated. In patients with predicted severe acute pancreatitis an on-demand feeding strategy is advised and when patients do not tolerate an oral diet after 72 hours, enteral nutrition can be started. The use of supplements, both parenteral as enteral, are not recommended. Optimal nutritional support in severe cases often requires a tailor-made approach with day-to-day evaluation of its effectiveness. PMID:26823272

    The acute phase response is characterised by the following sequence of principle phenomena: (1) an early local inflammatory reaction, (2) formation of inflammatory humoral factors inducing a systemic reaction, (3) stimulation of glycoprotein synthesis predominantly in the hepatocytes, and (4) an increase in the plasma concentration of acute phase proteins, when the rate of biosynthesis exceeds the degradation rate. Inflammatory mediators (lysosomal enzymes, oxygen derived radicals, prostaglandins) are mainly released during phagocytosis by granulocytes and macrophages. The signal reaching the hepatocytes is not yet clearly identified. A leukocyte endogenous mediator (LEM) released by macrophages is described. There is evidence that prostaglandins and probably proteinase alpha 2-macroglobulin complexes are also involved. The hepatic acute phase protein synthesis is modulated by hormones (insulin, cortisol, somatotropin). The biochemical events in the hepatocyte include an increase in protein synthesis and the regulatory control of the glycosylation of polypeptide precursors. The secreted glycoproteins serve variously as inhibitors or mediators of the inflammatory processes. PMID:6208159

    The acutely obstructed airway is a medical emergency that can potentially result in serious morbidity and mortality. Apart from the latest advancements in anaesthetic techniques, equipment and drugs, publications relevant to our topic, including the United Kingdom's 4th National Audit Project on major airway complications in 2011 and the updated American Society of Anesthesiologists' difficult airway algorithm of 2013, have recently been published. The former contained many reports of adverse events associated with the management of acute airway obstruction. By analysing the data and concepts from these two publications, this review article provides an update on management techniques for the acutely obstructed airway. We discuss the principles and factors relevant to the decision-making process in formulating a logical management plan. PMID:26996162

    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.

  2. Acute stress may induce ovulation in women

    PubMed Central

    2010-01-01

    Background This study aims to gather information either supporting or rejecting the hypothesis that acute stress may induce ovulation in women. The formulation of this hypothesis is based on 2 facts: 1) estrogen-primed postmenopausal or ovariectomized women display an adrenal-progesterone-induced ovulatory-like luteinizing hormone (LH) surge in response to exogenous adrenocorticotropic hormone (ACTH) administration; and 2) women display multiple follicular waves during an interovulatory interval, and likely during pregnancy and lactation. Thus, acute stress may induce ovulation in women displaying appropriate serum levels of estradiol and one or more follicles large enough to respond to a non-midcycle LH surge. Methods A literature search using the PubMed database was performed to identify articles up to January 2010 focusing mainly on women as well as on rats and rhesus monkeys as animal models of interaction between the hypothalamic-pituitary-adrenal (HPA) and hypothalamic-pituitary-gonadal (HPG) axes. Results Whereas the HPA axis exhibits positive responses in practically all phases of the ovarian cycle, acute-stress-induced release of LH is found under relatively high plasma levels of estradiol. However, there are studies suggesting that several types of acute stress may exert different effects on pituitary LH release and the steroid environment may modulate in a different way (inhibiting or stimulating) the pattern of response of the HPG axis elicited by acute stressors. Conclusion Women may be induced to ovulate at any point of the menstrual cycle or even during periods of amenorrhea associated with pregnancy and lactation if exposed to an appropriate acute stressor under a right estradiol environment.

    After the institution of positive-pressure ventilation, the use of noninvasive ventilation (NIV) through an interface substantially increased. The first technique was continuous positive airway pressure; but, after the introduction of pressure support ventilation at the end of the 20th century, this became the main modality. Both techniques, and some others that have been recently introduced and which integrate some technological innovations, have extensively demonstrated a faster improvement of acute respiratory failure in different patient populations, avoiding endotracheal intubation and facilitating the release of conventional invasive mechanical ventilation. In acute settings, NIV is currently the first-line treatment for moderate-to-severe chronic obstructive pulmonary disease exacerbation as well as for acute cardiogenic pulmonary edema and should be considered in immunocompromised patients with acute respiratory insufficiency, in difficult weaning, and in the prevention of postextubation failure. Alternatively, it can also be used in the postoperative period and in cases of pneumonia and asthma or as a palliative treatment. NIV is currently used in a wide range of acute settings, such as critical care and emergency departments, hospital wards, palliative or pediatric units, and in pre-hospital care. It is also used as a home care therapy in patients with chronic pulmonary or sleep disorders. The appropriate selection of patients and the adaptation to the technique are the keys to success. This review essentially analyzes the evidence of benefits of NIV in different populations with acute respiratory failure and describes the main modalities, new devices, and some practical aspects of the use of this technique.

    This study sought to compare the antimicrobial susceptibility rates between acute uncomplicated cystitis patients with failed initial antimicrobial treatment, who were considered unresolved cases, and newly presenting acute uncomplicated cystitis patients without recent antimicrobial use within 3 months and to determine whether different treatment strategies should be applied according to recent antimicrobial exposure (RAE). Female acute uncomplicated cystitis patients with Escherichia coli growth, who visited our hospital's urology department from 2010 to 2014, were divided according to RAE. The antimicrobial susceptibility of E. coli was compared between the group with RAE and the group with no antimicrobial exposure (NAE) within 3 months. The total number of acute uncomplicated cystitis patients with E. coli growth was 259: 40 patients comprised the RAE group and 219 patients formed the NAE group. The mean age was significantly older and previous recurrent cystitis history was higher in the RAE group (p < 0.05). Furthermore, the antimicrobial susceptibility of E. coli to amoxicillin-clavulanic acid, cefotaxime, cefoxitin, ciprofloxacin, and trimethoprim-sulfamethoxazole was significantly lower in the RAE group, with susceptibility results of 64.7%/88.0% (RAE/NAE), 77.5%/89.0%, 79.4%/95.3%, 31.3%/64.2%, and 42.5%/70.6%, respectively. RAE was an independent factor for antimicrobial resistance. This study showed that antimicrobial susceptibilities were significantly lower in acute uncomplicated cystitis patients with failed initial antimicrobial treatment, who are defined as unresolved cases. Our results suggest that first-line antimicrobials might show poor efficacy in cases of unresolved, acute uncomplicated cystitis and alternative or secondary antimicrobials should be considered in these cases.

    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.

    There have been conflicting results regarding a correlation between CD133 expression and disease outcome. To assess CD133 expression in patients with acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL) and to evaluate its correlation with the different clinical and laboratory data as well as its relation to disease outcome, the present study included 60 newly diagnosed acute leukemic patients; 30 ALL patients with a male to female ratio of 1.5:1 and their ages ranged from 9 months to 48 years, and 30 AML patients with a male to female ratio of 1:1 and their ages ranged from 17 to 66 years. Flow cytometric assessment of CD133 expression was performed on blast cells. In ALL, no correlations were elicited between CD133 expression and some monoclonal antibodies, but in AML group, there was a significant positive correlation between CD133 and HLA-DR, CD3, CD7 and TDT, CD13 and CD34. In ALL group, patients with negative CD133 expression achieved complete remission more than patients with positive CD133 expression. In AML group, there was no statistically significant association found between positive CD133 expression and treatment outcome. The Kaplan-Meier curve illustrated a high significant negative correlation between CD133 expression and the overall survival of the AML patients. CD133 expression is an independent prognostic factor in acute leukemia, especially ALL patients and its expression could characterize a group of acute leukemic patients with higher resistance to standard chemotherapy and relapse. CD133 expression was highly associated with poor prognosis in acute leukemic patients. PMID:23532815

    Decompression illness is a rare but serious complication of diving caused by intravascular or extravascular gas bubble formation. We report the first case of acute kidney injury in a 27-year-old diver following three rapid ascents. He presented with transient neurological symptoms and abdominal pain followed by rapidly progressive acute kidney injury (creatinine peak 1210 µmol/L) due to arterial air emboli. He received supportive care and 100% oxygen followed by hyperbaric therapy and recovered fully. Arterial air emboli caused by rapid decompression can affect multiple organs including the kidneys. Early transfer to a hyperbaric unit is important as complications may present delayed. PMID:25852912

    A 61-year-old man developed double vision subsequent to diarrheal illness. Mixed horizontal-vertical gaze palsy in both eyes, diminution of tendon reflexes, and gaze nystagmus were noted. His horizontal gaze palsy was accompanied by gaze nystagmus in the abducent direction, indicative of the disturbance in central nervous system. Neither limb weakness nor ataxia was noted. Serum anti-GQ1b antibody was detected. Brain magnetic resonance imaging (MRI) findings were normal. The patient was diagnosed as having acute ophthalmoparesis. The ophthalmoparesis and nystagmus gradually disappeared in 3 months. The accompanying nystagmus suggests that central nervous system disturbance may also be present with acute ophthalmoparesis.

    Trichloroethylene (TCE) is a chlorinated aliphatic hydrocarbon primarily utilized for vapor-phase degreasing in the fabricated metals industry. Other applications include cold-metal cleaning and use in the manufacture of organic chemicals. TCE enters the environment as a result of volatilization during its production and through its industrial uses. TCE has been detected in aquatic environments and organisms at part-per-trillion (pptr) concentrations. Although TCE is indicated to be widely distributed, relatively limited data exist on the acute effects of TCE on aquatic organisms, especially saltwater species. Results of static acute tests of TCE with a saltwater alga, invertebrate, and fish are reported here to enhance the data base.

    Atherosclerosis is a chronic inflammatory disease of the vessel wall and a major cause of death worldwide. One of atherosclerosis' most dreadful complications are acute coronary syndromes that comprise ST-segment elevation myocardial infarction, non-ST-segment elevation myocardial infarction, and unstable angina. We now understand that inflammation substantially contributes to the initiation, progression, and destabilization of atherosclerosis. In this review, we will focus on the role of inflammatory leukocytes, which are the cellular protagonists of vascular inflammation, in triggering disease progression and, ultimately, the destabilization that causes acute coronary syndromes.

    Acute pelvic pain in women is a routine situation in any emergency unit. The radiologist should know how to explore the patient with regards to the history and clinical findings. Ultrasonography is the primary and sometimes the only necessary imaging tool in the assessment of acute pelvic pain in women. MRI is the preferred technique in pregnant or young women. CT is more valuable for assessing nongynecologic disorders or post-partum and post-operative infections. This article reviews the contribution of each imaging technique in this clinical situation. Emphasis is put on the importance of age and clinical findings in the diagnostic strategy. PMID:18288036

    Accidental exposure to uranium is a matter of concern, as U(VI) is nephrotoxic in both human and animal models, and its toxicity is associated to chemical toxicity instead of radioactivity. We synthesized different PAMAM G4 and G5 derivatives in order to prove their interaction with uranium and their effect on the viability of red blood cells in vitro. Furthermore, we prove the effectiveness of the selected dendrimers in an animal model of acute uranium intoxication. The dendrimer PAMAM G4-Lys-Fmoc-Cbz demonstrated the ability to chelate the uranyl ion in vivo, improving the biochemical and histopathologic features caused by acute intoxication with uranium.

    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

    Neuroimaging plays a critical role in the management of patients with acute stroke syndrome, with diagnostic, therapeutic, and prognostic implications. A multiparametric magnetic resonance (MR) imaging protocol in the emergency setting can address both primary goals of neuroimaging (ie, detection of infarction and exclusion of hemorrhage) and secondary goals of neuroimaging (ie, identifying the site of arterial occlusion, tissue characterization for defining infarct core and penumbra, and determining stroke cause/mechanism). MR imaging provides accurate diagnosis of acute ischemic stroke (AIS) and can differentiate AIS from other potential differential diagnoses. PMID:27150320

    Acute megakaryoblastic leukemia (AMKL) comprises between 4% and 15% of newly diagnosed pediatric acute myeloid leukemia patients. AMKL in children with Down syndrome (DS) is characterized by a founding GATA1 mutation that cooperates with trisomy 21, followed by the acquisition of additional somatic mutations. In contrast, non–DS-AMKL is characterized by chimeric oncogenes consisting of genes known to play a role in normal hematopoiesis. CBFA2T3-GLIS2 is the most frequent chimeric oncogene identified to date in this subset of patients and confers a poor prognosis. PMID:26186939

    Diverticulitis is the most common clinical complication of diverticular disease, affecting 10-25% of the patients with diverticula. The prevalences of diverticulitis and colon cancer tend to increase with age and are higher in industrialized countries. Consequently, diverticulitis and colon cancer have been reported to have similar epidemiological characteristics. However, the relationship between these diseases remains controversial, as is the performance of routine colonoscopy after an episode of diverticulitis to exclude colon cancer. Recently, we experienced three cases of colon cancer after treating acute diverticulitis, based on which we suggest the importance of follow-up colonoscopy after acute diverticulitis. PMID:24032118

  1. Beta blocker eye drops for treatment of acute migraine.

    PubMed

    Migliazzo, Carl V; Hagan, John C

    2014-01-01

    We report seven cases of successful treatment of acute migraine symptoms using beta blocker eye drops. The literature on beta blockers for acute migraine is reviewed. Oral beta blocker medication is not effective for acute migraine treatment. This is likely due to a relatively slow rate of achieving therapeutic plasma levels when taken orally. Topical beta blocker eye drops achieve therapeutic plasma levels within minutes of ocular administration which may explain their apparent effectiveness in relief of acute migraine symptoms.

    The high mortality and morbidity can be significantly reduced by three cardinal steps: 1. Early diagnosis of intrinsic renal failure 2. Early institution of fluid restriction and dialysis 3. The identification of patients who are likely to be at high risk from acute renal failure, and the careful planning and institution of available therapeutic measures to prevent it. PMID:9155748

  4. Significance of Phi bodies in acute leukaemia.

    PubMed Central

    Cardullo, L de S; Morilla, R; Catovsky, D

    1981-01-01

    Material from 39 patients with acute leukaemia was investigated with the peroxidase cytochemical reaction using 3,3'diaminobenzidine (DAB) and other substrates in order to test their sensitivity in detecting myeloid differentiation. The proportion of positive blasts and of cases with Auer rods in acute myeloid leukaemia (AML) was significantly greater with DAB than with benzidine. In addition, Phi bodies were demonstrated in AML blasts only when DAB was used; Phi bodies were also observed in two out of seven cases of chronic granulocytic leukaemia in "myeloid" blast crisis but were not seen in any case of acute lymphoblastic leukaemia. Phi bodies were more numerous when the reaction was carried out at pH 9.7, and their number was significantly reduced in the presence of 3-amino 1,2,4-triazole. Both findings suggest that the Phi bodies derive from catalase-containing granules (microperoxisomes) and are distinct from Auer rods, which derive from peroxidase-containing (primary) granules. Like Auer rods, Phi bodies appear to be characteristics of immature myeloid cells in leukaemia but are seen with a higher frequency than Auer rods in acute myeloid leukemia.

    2010-03-01

    We investigated the efficacy of orally and topically applied Pycnogenol for the management of acute hemorrhoidal attacks in a controlled, randomized study with 84 subjects. Within less than 48 h of onset of an acute attack, patients were enrolled and signs and symptoms were scored. This evaluation was repeated after seven days' treatment and again seven days following treatment cessation. The decrease in scores was significantly more pronounced in the Pycnogenol-treated groups than in the control group given placebo (p < 0.05), showing the efficacy of Pycnogenol for relieving signs and symptoms of acute external hemorrhoids. In a group of patients given topical (0.5%) Pycnogenol in addition to oral Pycnogenol the improvement in symptoms set in significantly faster and was more pronounced. The most prominent symptom, hemorrhoidal bleeding, was completely absent in all patients treated with Pycnogenol for seven days and also at the 14 days follow-up. In contrast, bleedings were still observed in the control group during the two weeks follow-up. This study indicates that Pycnogenol, both in oral and in topical form, is effective for controlling this common, disabling health problem. The application of Pycnogenol eases the management of acute hemorrhoidal attacks and help avoid bleedings. PMID:20041428

    An intriguing and increasingly understood facet of immune responses is the ability of a recipient to destroy a foreign tissue or organ graft. The phenomenon of acute rejection of an allograft involves a series of complex and inter-related cellular and humoral events, culminating in graft death. Some of the current thinking surrounding this phenomenon is reviewed. PMID:1867525
