    We reported a case of acute pancreatitis as the complication of dengue hemorrhagic fever (DHF). This complication can cause more severe fatal condition, and difficulties in treatment, although it is rare. Dengue hemorrhagic fever (DHF) is one of the endemic diseases and often come as an outbreak event in South East Asia including Indonesia. Dengue hemorrhagic fever (DHF) is a global public health problem, because until now there has been no medicine to eradicate the dengue virus, no dengue vaccine and difficult to eradicate the mosquitoes as the contagious vector. Diagnosis and treatment of acute pancreatitis as early as possible is important to improve the patient's condition and survival. The patient was a 59 year old male and had been treated conservatively. The patient was admitted to the hospital, oral fasting until the fourth day, given parenteral nutrition, antibiotic and other intravenous medicines. Initial oral liquid diet was given on the fifth day of hospitalization and changed gradually according to the condition. The patient was then improved and discharged from the hospital.

    A 45-year-old woman was admitted to our hospital because of high fever and malaise. She also presented abnormal urine findings including macrohematuria and proteinuria with transient renal insufficiency. Salmonella Typhi was isolated from her blood and stool culture, and then she was diagnosed as having typhoid fever. Salmonella enterica serotype typhi infection can be complicated by renal involvement, although rare. In Japan, few cases have been reported about acute nephritic syndrome in typhoid fever. Here, we report a case of endemic acquired typhoid fever associated with acute renal failure probably due to acute nephritic syndrome successfully treated with levofloxacin.

    Dengue infection can have spectrum of manifestations, often with an unpredictable clinical progression and outcome. There have been increasing reports of atypical manifestations. Abdominal pain or tenderness and persistent vomiting (warning signs) are present in the majority of cases with severe dengue prior to clinical deterioration. We report a 10-year-old child who presented with fever, persistent vomiting, and abdominal pain. A diagnosis of acute pancreatitis was made. This is a very infrequently reported complication of dengue hemorrhagic fever.

    Full Text Available Dengue fever is a viral infection transmitted by the mosquito, Aedes aegypti. Cardiac rhythm disorders, such as atrioventricular blocks and ventricular ectopic beats, appear during infection and are attributed to viral myocarditis. However, supraventricular arrhythmias have not been reported. We present a case of acute atrial fibrillation, with a rapid ventricular rate, successfully treated with intravenous amiodarone, in a 62-year-old man with dengue hemorrhagic fever, who had no structural heart disease.

    Abstract Q fever is a neglected and potentially fatal disease. During acute Q fever, antiphospholipid antibodies are very prevalent and have been associated with fever, thrombocytopenia, acquired heart valve disease, and progression to chronic endocarditis. However, thrombosis, the main clinical criterion of the 2006 updated classification of the antiphospholipid syndrome, has not been assessed in this context. To test whether thrombosis is associated with antiphospholipid antibodies and whether the criteria for antiphospholipid syndrome can be met in patients with acute Q fever, we conducted a cross-sectional study at the French National Referral Center for Q fever. Patients included were diagnosed with acute Q fever in our Center between January 2007 and December 2015. Each patient's history and clinical characteristics were recorded with a standardized questionnaire. Predictive factors associated with thrombosis were assessed using a rare events logistic regression model. IgG anticardiolipin antibodies (IgG aCL) assessed by an enzyme-linked immunosorbent assay were tested on the Q fever diagnostic serum. A dose-dependent relationship between IgG aCL levels and thrombosis was tested using a receiver operating characteristic (ROC) analysis. Of the 664 patients identified for inclusion in the study, 313 (47.1%) had positive IgG aCL and 13 (1.9%) were diagnosed with thrombosis. Three patients fulfilled the antiphospholipid syndrome criteria. After multiple adjustments, only positive IgG aCL (relative risk, 14.46 [1.85–113.14], P = .011) were independently associated with thrombosis. ROC analysis identified a dose-dependent relationship between IgG aCL levels and occurrence of thrombosis (area under curve, 0.83, 95%CI [0.73–0.93], P antiphospholipid antibodies are associated with thrombosis, thrombocytopenia, and acquired valvular heart disease. Antiphospholipid antibodies should be systematically assessed in acute Q fever patients. Hydroxychloroquine

    Background: Clinical profile of acute rheumatic fever and rheumatic recurrence seems to have changed in countries where rheumatic fever is still endemic. The objectives of this study were to compare clinical profile and outcome of patients suffering initial and recurrent episodes of acute rheumatic fever in children. Methods: This prospective study was conducted in two tertiary care hospitals from January to June 2011. The diagnosis was based on the modified Jones criteria. Sixty children were included in the study, 15 having first episode of rheumatic fever and 45 with rheumatic recurrence. The severity of carditis was assessed by Clinical and echocardiography means. Results: Carditis was the commonest presentation in both first (80 percentage) and recurrent attacks (100 percentage). Arthritis was seen in 60 percentage of children with first episode and in 26.7 percentage with recurrence. The frequency of subcutaneous nodules, invariably associated with carditis, was very high (33.3 percentage in the first and 48.3 percentage in recurrent episodes). Carditis was generally mild during first episode (53.3 percentage) and severe with rheumatic recurrence (55.6 percentage). There was no death in either group. One patient with severe mitral regurgitation and rheumatic recurrence underwent mitral valve repair for intractable heart failure. Conclusion: Clinical profile of rheumatic recurrence and acute rheumatic fever has changed. Rheumatic recurrence is associated with severe carditis. Carditis is more common than arthritis even in the first attack. Sub-cutaneous nodules are a frequent finding invariably associated with carditis. (author)

    Chikungunya fever is a vector borne virus that typically causes a self-limiting systemic illness with fever, skin rash and joint aches 2 weeks after infection. We present the case of a 69-year-old woman presenting with an acute unilateral optic neuropathy as a delayed complication of Chikungunya virus (CHIKV) infection contracted during a recent trip to the West Indies. She presented to our ophthalmology department with acute painless visual field loss in the right eye and a recent flu-like illness. She was found to have a right relative afferent pupillary defect (RAPD) with unilateral optic disc swelling. Serology confirmed recent CHIKV infection. Treatment with intravenous methylprednisolone was delayed while awaiting MRI scans and serology results. At 5-month follow-up, there was a persistent right RAPD and marked optic atrophy with a corresponding inferior scotoma in the visual field. 2015 BMJ Publishing Group Ltd.

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

    Full Text Available Dengue fever is the world's most important viral hemorrhagic fever disease, the most geographically wide-spread of the arthropod-born viruses, and it causes a wide clinical spectrum of disease. We report a case of dengue hemorrhagic fever complicated by acute hepatitis. The initial picture of classical dengue fever was followed by painful liver enlargement, vomiting, hematemesis, epistaxis and diarrhea. Severe liver injury was detected by laboratory investigation, according to a syndromic surveillance protocol, expressed in a self-limiting pattern and the patient had a complete recovery. The serological tests for hepatitis and yellow fever viruses were negative. MAC-ELISA for dengue was positive.

    Dengue fever is an acute viral disease, which usually presents as a mild febrile illness. Patients with severe disease present with dengue haemorrhagic fever or dengue toxic shock syndrome. Rarely, it presents with abdominal symptoms mimicking acute appendicitis. We present a case of a male patient presenting with right iliac fossa pain and suspected acute appendicitis that was later diagnosed with dengue fever following a negative appendicectomy. A 13-year old male patient presented with fever, localized right-sided abdominal pain and vomiting. Abdominal ultrasound was not helpful and appendicectomy was performed due to worsening abdominal signs and an elevated temperature. A normal appendix with enlarged mesenteric nodes was found at surgery. Complete blood count showed thrombocytopenia with leucopenia. Dengue fever was now suspected and confirmed by IgM enzyme-linked immunosorbent assay against dengue virus. This unusual presentation of dengue fever mimicking acute appendicitis should be suspected during viral outbreaks and in patients with atypical symptoms and cytopenias on blood evaluation in order to prevent unnecessary surgery. This case highlights the occurrence of abdominal symptoms and complications that may accompany dengue fever. Early recognition of dengue fever mimicking acute appendicitis will avoid non-therapeutic operation and the diagnosis may be aided by blood investigations indicating a leucopenia, which is uncommon in patients with suppurative acute appendicitis.

    A 47-year-old man with recent travel to the Caribbean was admitted with acute febrileillness associated with arthralgia and skin rash followed by sudden onset of bilateral visual field defects. Funduscopy revealed subtle bilateral paracentral dark lesions nasal to the fovea best seen on near infrared imaging as hyporeflective, wedge-shaped, paracentral macular lesions. Spectral-domain optical coherence tomography (SD-OCT) through the lesions revealed hyperreflective bands at the level of the outer plexiform layer and outer nuclear layer (ONL), with concomitant attenuation of the underlying external limiting membrane (ELM), ellipsoid zone (EZ), and interdigitation zone (IZ). Neither fluorescein angiography nor speckle variance OCT angiography (sv-OCTA) showed any defects in retinal circulation. Work up revealed positive Immunoglobulin M for Chikungunya virus (CHIKV). Six months later, the patient had persistent scotomas, although reduced in size. SD-OCT showed subtle ONL thinning and restoration of the ELM, although EZ and IZ remained disrupted. Chikungunya fever may manifest as bilateral acute macular neuroretinopathy (AMN). Clinicians should be aware of possible systemic associations of AMN.

    Full Text Available Dengue fever (DF is an acute febrile illness that follows a self-limiting course. However, some patients suffer from complications, including myocarditis, due to the involvement of other organs. A child presented at the Aga Khan University Hospital in Karachi, Pakistan, in June 2013 with a high-grade fever, malaise and epigastric pain radiating to the chest. Positive DF antigen and immunoglobulin M assays confirmed the diagnosis of DF. Persistent bradycardia with low blood pressure led to further cardiac investigations which showed a decreased ejection fraction and raised serum cardiac enzymes, indicating myocardial damage. With supportive care and use of inotropes, the spontaneous normalisation of cardiac enzyme levels and ejection fraction was observed. The child was discharged five days after admission. This case highlights the importance of identifying myocarditis in DF patients suffering from cardiac symptoms that are not explained by other potential aetiologies. Awareness, early suspicion and supportive care are essential to ensure favourable outcomes.

    Coxiella burnetii endocarditis is considered to be a late complication of Q fever in patients with preexisting valvular heart disease (VHD). We observed a large transient aortic vegetation in a patient with acute Q fever and high levels of IgG anticardiolipin antibodies (IgG aCL). Therefore, we sought to determine how commonly acute Q fever could cause valvular vegetations associated with antiphospholipid antibody syndrome, which would be a new clinical entity. We performed a consecutive case series between January 2007 and April 2014 at the French National Referral Center for Q fever. Age, sex, history of VHD, immunosuppression, and IgG aCL assessed by enzyme-linked immunosorbent assay were tested as potential predictors. Of the 759 patients with acute Q fever and available echocardiographic results, 9 (1.2%) were considered to have acute Q fever endocarditis, none of whom had a previously known VHD. After multiple adjustment, very high IgG aCL levels (>100 immunoglobulin G-type phospholipid units; relative risk [RR], 24.9 [95% confidence interval {CI}, 4.5-140.2]; P = .002) and immunosuppression (RR, 10.1 [95% CI, 3.0-32.4]; P = .002) were independently associated with acute Q fever endocarditis. Antiphospholipid antibody syndrome with valvular vegetations in acute Q fever is a new clinical entity. This would suggest the value of systematically testing for C. burnetii in antiphospholipid-associated cardiac valve disease, and performing early echocardiography and antiphospholipid dosages in patients with acute Q fever. © The Author 2015.

  19. Acute rheumatic fever and rheumatic heart disease in indigenous populations.

    Science.gov (United States)

    Steer, Andrew C; Carapetis, Jonathan R

    2009-12-01

    Acute rheumatic fever and rheumatic heart disease are diseases of socioeconomic disadvantage. These diseases are common in developing countries and in Indigenous populations in industrialized countries. Clinicians who work with Indigenous populations need to maintain a high index of suspicion for the potential diagnosis of acute rheumatic fever, particularly in patients presenting with joint pain. Inexpensive medicines, such as aspirin, are the mainstay of symptomatic treatment of rheumatic fever; however, antiinflammatory treatment has no effect on the long-term rate of progression or severity of chronic valvular disease. The current focus of global efforts at prevention of rheumatic heart disease is on secondary prevention (regular administration of penicillin to prevent recurrent rheumatic fever), although primary prevention (timely treatment of streptococcal pharyngitis to prevent rheumatic fever) is also important in populations in which it is feasible.

    Introduction. Infectious diseases may present with atypical presentations in the geriatric patients. While fever is an important finding of infections, it may also be a sign of noninfectious etiology. Methods. Geriatric patients who were hospitalized for acute fever in our infectious diseases unit were included. Acute fever was defined as presentation within the first week of fever above 37.3°C. Results. 185 patients were included (82 males and 103 females). Mean age was 69.7 ± 7.5 years. The cause of fever was an infectious disease in 135 and noninfectious disease in 32 and unknown in 18 of the patients. The most common infectious etiologies were respiratory tract infections (n = 46), urinary tract infections (n = 26), and skin and soft tissue infections (n = 23). Noninfectious causes of fever were rheumatic diseases (n = 8), solid tumors (n = 7), hematological diseases (n = 10), and vasculitis (n = 7). A noninfectious cause of fever was present in one patient with no underlying diseases and in 31 of 130 patients with underlying diseases. Conclusion. Geriatric patients with no underlying diseases generally had infectious causes of fever while noninfectious causes were responsible from fever in an important proportion of patients with underlying diseases.

    2010-07-01

    This study aimed to determine the frequency, pattern and management of acute abdomen in patients with dengue fever. This descriptive case series is a prospective analysis of acute abdomen in dengue fever that was performed at three secondary care hospitals in Karachi, Pakistan from June 1, 2005 to December 31, 2008. The inclusion criterion was all patients with confirmed diagnosis of dengue fever. Patients with incomplete laboratory, ultrasound or histopathology data were excluded. Among 357 patients with dengue fever, 43 (12.04%) had acute abdomen. There were 15 men and 28 women, with a median age of 29 years. These included 26 cases of acute cholecystitis, 7 cases of acute appendicitis, 7 cases of nonspecific peritonitis, and 3 cases of acute pancreatitis. Dengue hemorrhagic fever/shock syndrome was found in acute pancreatitis, and two of these patients died. Emergency surgery was required in eight patients (5 appendectomy and 3 open cholecystectomy). Substantial transfusion of blood and its components was required in eight patients who underwent emergency surgery. Early diagnosis and prompt conservative management of dengue acute abdomen is necessary to avoid mortality and emergency surgery-related morbidity. However, if needed, surgery can be performed with acceptable morbidity. Copyright © 2010 Asian Surgical Association. Published by Elsevier B.V. All rights reserved.

    In rats synthesis of some acute phase reactants can be induced by a combination of corticosteroids and adrenaline. During fever both hormones show high plasma levels. We studied the effect of fever induced by intra-cerebroventricular (i.c.v.) injection of PGE2 on the acute phase response. Fever was continuously recorded and 24 h after induction acute phase reactant (APR) response was measured as indicated by the rise of alpha-macrofetoprotein (alpha M FP, alpha 2 macroglobulin of the rat). Controls received 0.9% saline i.c.v. Controls did not develop fever (dTmax less than or equal to 1 degree C) nor did they show significant APR response. The maximal rise in body temperature after PGE2 (2.6 +/- 0.7 degrees C) correlated significantly with the rise in alpha M FP concentration 24 h later. Adrenalectomy prevented the APR response completely but the magnitude of the fever reaction remained the same (2.1 +/- 0.3 degrees C). alpha-Blockade gave a smaller fever response but had no effect on the APR response. In alpha- and beta-blockade, fever response was normal but no APR response was obtained. Destroying the sympathetic nerve supply to the liver with 6-OH dopamine retarded the fever response but again APR response was not impeded. In order to differentiate between the role of fever as such and the effect of PGE2 on APR synthesis, we used heat exposure to induce hyperthermia in normal rats who showed an APR response comparable with that after i.c.v. PGE2. Pretreatment with sodium salicylate before inducing hyperthermia led to a variable rise in alpha M FP. Fever as such, without tissue injury, induces an APR response. The pathway to this effect probably involves circulating corticosterone and adrenaline, possibly via a beta-receptor mediated stimulation. PMID:2460123

    Rheumatic heart disease remains an important cause of acquired heart disease in developing countries. Although prevention of rheumatic fever and management of recurrences have been well established, optimal management of active rheumatic carditis remains unclear. This is an update of a review published in 2003, and previously updated in 2009 and 2012. To assess the effects, both harmful and beneficial, of anti-inflammatory agents such as aspirin, corticosteroids and other drugs in preventing or reducing further valvular damage in patients with acute rheumatic fever. We searched the Cochrane Central Register of Controlled Trials (2013, Issue 9 of 12), MEDLINE (Ovid, 1948 to 2013 October Week 1), EMBASE (Ovid, 1980 to 2013 Week 41) and Latin American Caribbean Health Sciences Literature (LILACS) (1982 to 17 October 2013). We last searched Index Medicus (1950 to April 2001) in 2001. We checked reference lists of identified studies and applied no language restrictions. Randomised controlled trials comparing anti-inflammatory agents (e.g. aspirin, steroids, immunoglobulins, pentoxifylline) versus placebo or controls, or comparing any of the anti-inflammatory agents versus one another, in adults and children with acute rheumatic fever diagnosed according to Jones, or modified Jones, criteria. The presence of cardiac disease one year after treatment was the major outcome criterion selected. Two review authors extracted data and assessed risk of bias using the methodology outlined in the Cochrane Handbook of Systematic Reviews of Interventions. Standard methodological procedures as expected by The Cochrane Collaboration were used. No new studies were included in this update. Eight randomised controlled trials involving 996 people were selected for inclusion in the review. Researchers compared several steroidal agents such as corticotrophin, cortisone, hydrocortisone, dexamethasone, prednisone and intravenous immunoglobulin versus aspirin, placebo or no treatment. Six

    The incidence of dengue fever is on the rise in tropical countries. In Sri Lanka, nearly 45,000 patients were reported in 2012. With the increasing numbers, rare manifestations of dengue are occasionally encountered. We report a patient who presented with bilateral cerebellar signs as the presenting feature of dengue. A 45-year-old previously healthy female from the suburbs of Colombo, Sri Lanka presented with an acute febrile illness associated with unsteadiness of gait. Clinical examination revealed a scanning dysarthria and marked horizontal nystagmus with bilateral dysmetria, dysdiadokokinesia and incordination more prominent on the right. Her gait was wide-based and ataxic with a tendency to fall to the right more than to the left. Dengue nonstructural protein antigen 1 test and IgM antibody testing both became positive indicating acute dengue infection. She recovered from the febrile episode within 9 days since the onset of fever but cerebellar symptoms outlasted the fever by one week. The magnetic resonance imaging of brain was normal and cerebellar signs resolved spontaneously by day 17 of the illness. Cerebellar syndrome in association with dengue fever has been reported in only four instances and our patient is the first reported case of dengue fever presenting with cerebellitis as the first manifestation of disease. This case report is intended to highlight the occurrence of acute cerebellitis as a presenting syndrome of the expanding list of unusual neurological manifestations of dengue infection.

    Q fever is a neglected and potentially fatal disease. During acute Q fever, antiphospholipid antibodies are very prevalent and have been associated with fever, thrombocytopenia, acquired heart valve disease, and progression to chronic endocarditis. However, thrombosis, the main clinical criterion of the 2006 updated classification of the antiphospholipid syndrome, has not been assessed in this context. To test whether thrombosis is associated with antiphospholipid antibodies and whether the criteria for antiphospholipid syndrome can be met in patients with acute Q fever, we conducted a cross-sectional study at the French National Referral Center for Q fever.Patients included were diagnosed with acute Q fever in our Center between January 2007 and December 2015. Each patient's history and clinical characteristics were recorded with a standardized questionnaire. Predictive factors associated with thrombosis were assessed using a rare events logistic regression model. IgG anticardiolipin antibodies (IgG aCL) assessed by an enzyme-linked immunosorbent assay were tested on the Q fever diagnostic serum. A dose-dependent relationship between IgG aCL levels and thrombosis was tested using a receiver operating characteristic (ROC) analysis.Of the 664 patients identified for inclusion in the study, 313 (47.1%) had positive IgG aCL and 13 (1.9%) were diagnosed with thrombosis. Three patients fulfilled the antiphospholipid syndrome criteria. After multiple adjustments, only positive IgG aCL (relative risk, 14.46 [1.85-113.14], P = .011) were independently associated with thrombosis. ROC analysis identified a dose-dependent relationship between IgG aCL levels and occurrence of thrombosis (area under curve, 0.83, 95%CI [0.73-0.93], P antiphospholipid antibodies are associated with thrombosis, thrombocytopenia, and acquired valvular heart disease. Antiphospholipid antibodies should be systematically assessed in acute Q fever patients. Hydroxychloroquine, which has been

    Typhoid fever is an enteric infection caused by Salmonella typhi. In Indonesia, typhoid fever is endemic with high incidence of the disease. In daily practice we frequently have patients with bronchial asthma, and it is becoming worse when these patients get typhoid fever. After oral ingestion, Salmonella typhi invades the the intestine mucosa after conducted by microbial binding to epithelial cells, destroying the microfold cells (M cell) then passed through the lamina propria and detected by dendritic cells (DC) which express a variety of pathogen recognition receptors on the surfaces, including Toll-Like Receptor (TLR). expressed on macrophages and on intestinal epithelial cells inducing degradation of IB, and translocation of NF-B (Nuclear Factor-Kappa Beta). This process initiates the induction of pro-inflammatory gene expression profile adhesion molecules, chemokines, adhesion molecules, and other proteins that induce and perpetuate the inflammation in host cells then will induce acute ant intractable attack of bronchial asthma. The role of typhoid fever in bronchial asthma, especially in persons with acute attack of bronchial asthma, is not well understood. In this article, we will discuss the role of typhoid fever in the bronchial asthma patients which may cause bronchial asthma significantly become more severe even triggering the acute and intractable attack of bronchial asthma. This fact makes an important point, to treat completely the typhoid fever in patients with bronchial asthma.

    Full Text Available To review the characteristics of reported outbreaks of acute rheumatic fever in the United States, and to determine if there is an increase in the incidence of acute rheumatic fever in the population served by the Hospital for Sick Children, Toronto, Ontario, the authors conducted a literature search and a retrospective review of inpatients and outpatients, satisfying the revised Jones criteria for the diagnosis of acute rheumatic fever, from 1972 to 1988. Patients satisfying the revised Jones criteria for the time period 1972–88 were included in the study. There have been eight articles reporting an increase in acute rheumatic fever in the United States. In three, the majority of children were white and from middle class suburban/rural communities in different geographic locations. Mucoid strains of group A streptococci were implicated but not confirmed as being associated with the outbreaks in three. The results of the chart review at the Hospital for Sick Children revealed that 83 cases satisfied the revised Jones criteria. The number of cases per 100,000 children (aged 18 years or less per year, decreased progressively over the study period. Polyarthritis was the most frequently seen major criterion occurring in 73% of patients (61 of 83. The most frequently affected ethnic groups were Italians 23%, Afro-Canadians 19% and Orientals 8%. The reported outbreaks in the United States are multifocal and predominantly confined to white middle class children residing in suburban/rural communities. There was no evidence of an increase in the number of cases of acute rheumatic fever seen in the population served by the Hospital for Sick Children; there was a progressive decline in number of cases over the study period. The results facilitate the characterization of acute rheumatic fever within North America into three different patterns of occurrence.

    Minimal information is available on the incidence of Crimean–Congo hemorrhagic fever (CCHF) virus and hantavirus infections in Georgia. From 2008 to 2011, 537 patients with fever ≥ 38°C for ≥ 48 hours without a diagnosis were enrolled into a sentinel surveillance study to investigate the incidence of nine pathogens, including CCHF virus and hantavirus. Of 14 patients with a hemorrhagic fever syndrome, 3 patients tested positive for CCHF virus immunoglobulin M (IgM) antibodies. Two of the patients enrolled in the study had acute renal failure. These 2 of 537 enrolled patients were the only patients in the study positive for hantavirus IgM antibodies. These results suggest that CCHF virus and hantavirus are contributing causes of acute febrile syndromes of infectious origin in Georgia. These findings support introduction of critical diagnostic approaches and confirm the need for additional surveillance in Georgia. PMID:24891463

    Dengue is the most important human viral disease transmitted by mosquitoes. It can be asymptomatic or it can present in any of its 3clinical forms: Dengue fever, dengue haemorrhagic fever and dengue shock syndrome. However, some atypical manifestations have been reported in surgical emergencies caused by acute appendicitis in patients with dengue fever. We report the case of an 18-year-old Mexican male who presented to the emergency department of the General Hospital of Culiacan, Sinaloa, with symptoms of dengue fever, accompanied by crampy abdominal pain with positive Rovsing and Dunphy signs. Dengue infection was confirmed by a positive NS1 antigen test performed by enzyme-linked immunosorbent assay. An abdominal ultrasound revealed an appendicular process; as the abdominal pain in the right side kept increasing, an open appendectomy was performed. Abundant inflammatory liquid was observed during the surgery, and the pathology laboratory reported an oedematous appendix with fibrinopurulent plaques, which agreed with acute ulcerative appendicitis. The patient was discharged fully recovered without complications during the follow-up period. Acute abdominal pain can be caused in some cases by dengue infection. This can be confusing, which can lead to unnecessary surgical interventions, creating additional morbidities and costs for the patient. This unusual and coincident acute appendicitis with dengue highlights the importance of performing careful clinical studies for appropriate decision making, especially in dengue endemic regions during an outbreak of this disease.

    Full Text Available Hemorrhagic complications of optic pathway diseases are extremely rare causes of acute visual loss associated with dengue fever. In this paper we report a patient presenting with dengue fever and bilateral acute visual loss caused by chiasmal compression due to Rathke's cleft cyst apoplexy. Considering the importance of early diagnosis and treatment to visual recovery, apoplexy of sellar and suprasellar tumors should be considered in the differential diagnosis of patients with acute visual loss and dengue fever.

    Rheumatic fever is an inflammatory disease that may develop after a Group A streptococcal infection and can involve the heart, joints, skin, and brain. A migrating polyarthritis after throat infection with group A β-haemolytic streptococci is classically attributed to acute rheumatic fever (ARF). Sterile non-migratory arthritis may occur as a separate entity, the so called post streptococcal reactive arthritis (PSRA). This study aimed to identify clinical and serological differences of patients with reactive arthritis after infection with Lance field group Aβ-haemolytic streptococci, compared with acute rheumatic fever. Hundred and twenty patients were recruited for the study , they were classified into two groups according to the diagnosis of ARF and PSRA patients consecutively seen in the Rheumatology and the Pediatric wards. Clinical and laboratory data were assessed through a questionnaire. The diagnosis of rheumatic fever was made based on revised modified Jones' criteria, while the diagnosis of post streptococcal reactive arthritis was made based on Deighton criteria; these associated with laboratory data, electrocardiography, chest X-ray, and bi-dimensional echocardiography. Results revealed no significant differences between both groups as regard age where ρ>0.05, while there were a significant difference regarding the date of antecedent upper respiratory tract infection (ρ 0.05). Regarding the cardio logical changes P-R interval by ECG was prolonged in 19 patients (31.67%)and Echo study showed changes in 12 patient (20%) of cases of ARF patient only. On the basis of simple laboratory variables and management, it ws possible to differentiate ARF from PSRA patients. So it could be concluded that these two conditions are actually distinct identities

    Assess clinical and serological data as parameters indicative of a possible evolution to endocarditis after an episode of acute Q fever. Retrospective cohort study of evolution to endocarditis after an acute Q fever episode, analyzing the clinical and serological evolution and the antibiotic treatment administered. Eighty patients were recruited, 20% of whom had phase i IgG antibody levels ≥ 1:1024 in the first 3 months. Only 44% of the patients underwent antibiotherapy in the acute phase; only 2 patients underwent extended antibiotherapy. Fifteen percent of the patients underwent an echocardiogram. None of the patients had symptoms suggestive of chronic infection or progressed to endocarditis after a median follow-up of 100 months, regardless of the early increase in phase i IgG antibodies. The early increase in phase i IgG antibodies in asymptomatic patients is not associated with progression to endocarditis despite not undergoing prolonged antibiotic treatment.

    Full Text Available Serological follow-up of acute Q-fever patients is important for detection of chronic infection but there is no consensus on its frequency and duration. The 2007-2009 Q-fever epidemic in the Netherlands allowed for long-term follow-up of a large cohort of acute Q-fever patients. The aim of this study was to validate the current follow-up strategy targeted to identify patients with chronic Q-fever.A cohort of adult acute Q-fever patients, diagnosed between 2007 and 2009, for whom a twelve-month follow-up sample was available, was invited to complete a questionnaire and provide a blood sample, four years after the acute episode. Antibody profiles, determined by immunofluorescence assay in serum, were investigated with a special focus on high titres of IgG antibodies against phase I of Coxiella burnetii, as these are considered indicative for possible chronic Q-fever.Of the invited 1,907 patients fulfilling inclusion criteria, 1,289 (67.6% were included in the analysis. At any time during the four-year follow-up period, 58 (4.5% patients were classified as possible, probable, or proven chronic Q-fever according to the Dutch Q-fever Consensus Group criteria (which uses IgG phase I ≥1:1,024 to as serologic criterion for chronic Q-fever. Fifty-two (89.7% of these were identified within the first year after the acute episode. Of the six patients that were detected for the first time at four-year follow-up, five had an IgG phase I titre of 1:512 at twelve months.A twelve-month follow-up check after acute Q-fever is recommended as it adequately detects chronic Q-fever in patients without known risk factors. Additional serological and clinical follow-up is recommended for patients with IgG phase I ≥1:512, as they showed the highest risk to progress to chronic Q-fever.

    Dengue infection is the most rapidly spreading mosquito-borne viral disease in the world and an estimated 50 million dengue infections reported annually. The pathogenesis of Thrombocytopenia in dengue fever (DF) is not clearly understood. Increased peripheral destruction of antibody coated platelets and acute bone marrow suppression were strongly suspected as the possible mechanism. This often leads to life threatening dengue hemorrhagic fever (DHF) and Dengue shock syndrome (DSS). Steroids are used in the treatment of Idiopathic thrombocytopenic purpura to increase the platelet count which is mediated by auto antibodies .This hypothesis would support the use of steroids in dengue fever. The objective of this study was to test whether an intravenous high dose dexamethasone was efficacious in increasing the platelet count in acute stage of dengue fever with thrombocytopenia. During the study period between June 2010 - 2011 in JSS Hospital Mysore, 127 patients were screened for dengue fever with thrombocytopenia (dengue fever.

    To describe an unusual retinal manifestation of dengue fever in an endemic region. A 35 year old male presenting with acute onset decreased vision in his right eye, was found to have a massive retinal pigment epithelial detachment (PED) extending up to the vascular arcades. He had been diagnosed with acute hypokalemic quadriparesis in dengue fever in the preceding week, which had resolved following treatment. The patient was managed conservatively. At three months follow up, there was spontaneous flattening of the PEDs with improvement in visual acuity. Dengue fever complicated by acute hypokalemic quadriparesis can be associated with PED, which can be large. The condition resolves spontaneously and bears a good prognosis.

    Hemorrhagic fever with renal syndrome (HFRS) and Crimean-Congo hemorrhagic fever (CCHF) are the 2 widespread viral hemorrhagic fevers occurring in Europe. HFRS is distributed throughout Europe, and CCHF has been reported mainly on the Balkan Peninsula and Russia. Both hemorrhagic fevers are endemic in Bulgaria. We investigated to what extent acute undifferentiated febrile illness in Bulgaria could be due to hantaviruses or to CCHF virus. Using enzyme-linked immunosorbent assays (ELISAs), we tested serum samples from 527 patients with acute febrile illness for antibodies against hantaviruses and CCHF virus. Immunoglobulin M (IgM) antibodies against hantaviruses were detected in 15 (2.8%) of the patients. Of the 15 hantavirus-positive patients, 8 (1.5%) were positive for Dobrava virus (DOBV), 5 (0.9%) were positive for Puumala virus (PUUV), and the remaining 2 were positive for both hantaviruses. A plaque reduction neutralization test (PRNT) confirmed 4 of the 10 DOBV-positive samples. PRNT was negative for all PUUV-positive samples. Serologic evidence of recent CCHF virus infection was found in 13 (2.5%) of the patients. Interestingly, HFRS and CCHF were not only detected in well-known endemic areas of Bulgaria but also in nonendemic regions. Our results suggested that in endemic countries, CCHF and/or HFRS might appear as a nonspecific febrile illness in a certain proportion of patients. Physicians must be aware of possible viral hemorrhagic fever cases, even if hemorrhages or renal impairment are not manifested.

    Rickettsial infections and Q fever present similarly to other acute febrile illnesses, but are infrequently diagnosed because of limited diagnostic tools. Despite sporadic reports, rickettsial infections and Q fever have not been prospectively studied in Central America. We enrolled consecutive patients presenting with undifferentiated fever in western Nicaragua and collected epidemiologic and clinical data and acute and convalescent sera. We used ELISA for screening and paired sera to confirm acute (≥4-fold rise in titer) spotted fever and typhus group rickettsial infections and Q fever as well as past (stable titer) infections. Characteristics associated with both acute and past infection were assessed. We enrolled 825 patients and identified acute rickettsial infections and acute Q fever in 0.9% and 1.3%, respectively. Clinical features were non-specific and neither rickettsial infections nor Q fever were considered or treated. Further study is warranted to define the burden of these infections in Central America.

    Scrub typhus usually presents as acute undifferentiated fever. This cross-sectional study included adult patients presenting with acute undifferentiated fever defined as any febrile illness for ≤ 14 days without evidence of localized infection. Scrub typhus cases were defined by an antibody titer of a ≥ fourfold increase in paired sera, a ≥ 1:160 in a single serum using indirect immunofluorescence assay, or a positive result of the immunochromatographic test. Multiple regression analysis identified predictors associated with scrub typhus to develop a prediction rule. Of 250 cases with known etiology of acute undifferentiated fever, influenza (28.0%), hepatitis A (25.2%), and scrub typhus (16.4%) were major causes. A prediction rule for identifying suspected cases of scrub typhus consisted of age ≥ 65 years (two points), recent fieldwork/outdoor activities (one point), onset of illness during an outbreak period (two points), myalgia (one point), and eschar (two points). The c statistic was 0.977 (95% confidence interval = 0.960-0.994). At a cutoff value ≥ 4, the sensitivity and specificity were 92.7% (79.0-98.1%) and 90.9% (86.0-94.3%), respectively. Scrub typhus, the third leading cause of acute undifferentiated fever in our region, can be identified early using the prediction rule. © The American Society of Tropical Medicine and Hygiene.

    Full Text Available Aim: to study clinical efficacy, tolerance and safety of a new pelleted ibuprofen form for children in treatment of fever in patients with acute respiratory tract infection. Patients and methods: children aged from 6 to 12 years old with clinical manifestation of respiratory tract infections and requiring antipyretic treatment were included into the study. Children (n = 50 were administered ibuprofen at a single dose of 5–10 mg/kg of body weight, not more than 3–4 times per day. The efficacy assessment included time needed for temperature decrease (assessment was performed in 15, 30 and 60 minutes and duration of the antipyretic effect (assessment in 6, 8 and 12 hours. Rapidity of analgesic effect in children with ear ache, headache and myalgias was performed in 15, 30, 60 minutes and 6, 8 and 12 hours after the drug intake. Results: antipyretic effect of pelleted ibuprofen for children begins in 15 minutes after its intake. Stable temperature decrease during the first 6 hours was observed in 58% of children (the mean temperature was 37,1 ± 0,3 and maintained up for 12 hours. Relief of pain intensity was established in 62,1% of patients during the first 3 hours, and in 37,9% the pain syndrome was arrested completely. Conclusions: the new pelleted form of ibuprofen for children was proved to have high clinical efficacy and safety in treatment of fever in children with acute respiratory tract infections.

    Full Text Available Q fever is serologically cross-reactive with other intracellular microorganisms. However, studies of the serological status of Mycoplasma pneumoniae and Chlamydophila pneumoniae during Q fever are rare. We conducted a retrospective serological study of M. pneumoniae and C. pneumoniae by enzyme-linked immunosorbent assay (ELISA, a method widely used in clinical practice, in 102 cases of acute Q fever, 39 cases of scrub typhus, and 14 cases of murine typhus. The seropositive (57.8%, 7.7%, and 0%, p<0.001 and seroconversion rates (50.6%, 8.8%, and 0%, p<0.001 of M. pneumoniae IgM, but not M. pneumoniae IgG and C. pneumoniae IgG/IgM, in acute Q fever were significantly higher than in scrub typhus and murine typhus. Another ELISA kit also revealed a high seropositivity (49.5% and seroconversion rate (33.3% of M. pneumoniae IgM in acute Q fever. The temporal and age distributions of patients with positive M. pneumoniae IgM were not typical of M. pneumoniae pneumonia. Comparing acute Q fever patients who were positive for M. pneumoniae IgM (59 cases with those who were negative (43 cases, the demographic characteristics and underlying diseases were not different. In addition, the clinical manifestations associated with atypical pneumonia, including headache (71.2% vs. 81.4%, p=0.255, sore throat (8.5% vs. 16.3%, p=0.351, cough (35.6% vs. 23.3%, p=0.199, and chest x-ray suggesting pneumonia (19.3% vs. 9.5%, p=0.258, were unchanged between the two groups. Clinicians should be aware of the high seroprevalence of M. pneumoniae IgM in acute Q fever, particularly with ELISA kits, which can lead to misdiagnosis, overestimations of the prevalence of M. pneumoniae pneumonia, and underestimations of the true prevalence of Q fever pneumonia.

    Chikungunya fever (CHIK) is an arboviral disease. Dengue fever (DENG) and CHIK are indistinguishable clinically and need to be differentiated by laboratory investigations. This study aimed at estimating the seroprevalence of CHIK mono-infection and CHIK and DENG dual infection in suspected patients. We also analyzed the age, sex distribution, joint involvement, and relation of joint movement restriction with visual analog scale (VAS). Two hundred patients clinically suspected with DENG and CHIK were enrolled from a Tertiary Care Hospital in Mumbai from April 2012 to October 2013. The detailed history and examination findings were recorded. Serum samples were subjected to DENG and CHIK immunoglobulin G (IgM) enzyme-linked immunosorbent assay (ELISA). The seroprevalence of CHIK was 12.5%. Mono-infection of CHIK was 3%, and CHIK and DENG dual infection was 9.5%. Most affected age group in CHIK cases was 46-60 years wherein female preponderance was seen. All 6 patients with CHIK mono-infection had fever and joint involvement; knee and elbow were the most commonly affected joints. All CHIK patients had VAS score of 6-10 with restricted joint movement. Of the patients with dual infection, the majorities were from 31 to 45 years with male preponderance; all had fever and joint pain mainly affecting knee and elbow. Of patients who had VAS score 6-10 in patients with dual infection, only 5.26% had restricted joint movement. IgM ELISA for Chikungunya infection should be included in the routine laboratory tests for acute febrile illness.

     The prevention of Q fever endocarditis through the use of systematic echocardiography and antibiotic prophylaxis in patients with acute Q fever and valvulopathy has never been validated in a cohort study.  From 2007 to 2012, all patients followed at the French National Referral Center for acute Q fever were included in a cohort study. The prevention of endocarditis included a systematic transthoracic echocardiography (TTE) and a 12-month course of doxycycline and hydroxychloroquine prophylaxis in patients with significant valvulopathy. Transesophageal echocardiography (TEE) was performed in patients with a negative TTE and a rapid rise of phase I immunoglobulin G titers.  Seventy-two patients were included with a median follow-up time of 22 months. A valvulopathy was identified in 31 patients (43%), being previously unknown in 24 (33%) and diagnosed only upon TEE or a second TTE in 7 (10%). The major determinants associated with endocarditis were age (hazard ratio [HR], 1.07; 95% confidence interval [CI], 1.006-1.13; P = .03), aortic regurgitation (HR, 10.2; 95% CI, 3.2-32.2; P valvulopathy.  Acute Q fever could be associated with an increased prevalence of valvulopathy. The evolution from acute Q fever to endocarditis is associated with age and valvulopathy and can be entirely prevented by antibiotic prophylaxis. Although the name "chronic Q fever" suggests otherwise, rapid evolution (<1 month) was observed.

    Full Text Available Introduction: Dengue haemorrhagic fever is known for its haemorrhagic and neurologic complications. Neurologic complications are caused by three mechanism namely neurotropism, systemic complications causing encephalopathy and postinfectious immune-mediated mechanisms. However acute compressive neuropathy due to haemorrhage is not frequent and we could find no literature describing this Case Report: We report a case of acute compressive ulnar neuropathy due to peri neural hematoma, following an attempt at intravenous cannulation in the cubital fossa in a patient of dengue haemorrhagic fever with thrombocytopenia. Immediate fasciotomy and removal of haematoma was performed to relieve the symptoms. Conclusion: Compression neuropathies can be seen in dengue hemorrhagic fever and removal of compressing hematoma relieves symptoms.

    Full Text Available Acute rheumatic fever remains a public health concern in developing countries as well as in poorer communities and among indigenous populations in some developed nations. It poses serious economic problem at individual, communal and national levels through direct and indirect health care costs. The objective of this article is to review acute rheumatic fever in the global context with some emphasis on the continuing burden of this disease in the developing settings. The Cochrane Database of Systematic Reviews, PubMed, EMBASE and AJOL were searched with focus on epidemiology, pathogenesis, diagnosis and treatment, and control of acute rheumatic fever. The review shows that acute rheumatic fever still occurs under conditions of impoverished overcrowding and poor sanitation and where access to healthcare services is limited. Since acute rheumatic fever is a preventable disease, improved housing and sanitation, access to effective healthcare services, early diagnosis, registration of cases and follow up remain the bedrock of the control of this disease [Archives Medical Review Journal 2013; 22(2.000: 153-169

    OBJECTIVES: Severe infection is a frequent cause of admission to an acute medical unit (AMU). However, not all infected patients present with fever. The aim was to assess differences in 30-day mortality among patients hospitalized with community-acquired severe infection presenting with hypo......-, normo- or fever. METHODS: A retrospective single-center follow-up at an AMU from August 1 2009 to August 31 2011. Patients were included the first time they presented with severe infection within the study period. Temperature was categorized into hypothermia (...), and fever (>38.0C). Severe infection was defined as a discharge diagnosis indicating infection combined with organ failure within the first 24 hours after arrival. Multivariable Cox regression analysis was computed to assess the association between temperature and 30-day mortality. RESULTS: A total of 2...

    Q fever is a widespread zoonotic infection caused by Coxiella burnetii (C. burnetii). Acute infection varies from a self-limited flu-like illness to pneumonia or hepatitis. A retrospective case study from March 2003 to December 2011 was conducted in the Hospital Son Llàtzer in Palma de Mallorca. Acute Q-fever was diagnosed in a patient with clinical suspicion and IgM in phase ii positive (≥ 1/40), with a positive IgG (≥1/80), or when IgG seroconversion was observed during convalescence. A total of 87 cases of acute Q fever were diagnosed. The median age was 50 years (range 21-89), and 69 (79.3%) were male. Fever and headache were the most common symptoms. Pneumonia was diagnosed in 39 (44.8%) patients, febrile episode in 21 (24.1%), and acute hepatitis in 23 (25.6%). Increased serum transaminases were observed in 19 (21.8%). Doxycycline was prescribed in 29 cases (33.4%). There were 30 (34.5%) patients lost to follow up after hospital discharge. A favorable outcome was observed in all other cases. Only one new case progressed to chronic Q fever. A total of 87 cases of acute Q fever were diagnosed. The median age was 50 years (range 21-89), and 69 (79.3%) were male. Fever and headache were the most common symptoms. Pneumonia was diagnosed in 39 (44.8%) patients, febrile episode in 21 (24.1%), and acute hepatitis in 23 (25.6%). Increased serum transaminases were observed in 19 (21.8%). Doxycycline was prescribed in 29 cases (33.4%). There were 30 (34.5%) patients lost to follow up after hospital discharge. A favorable outcome was observed in all other cases. Only one new case progressed to chronic Q fever. Acute Q fever acute is common our environment. Pneumonia was the most common clinical presentation. Even although doxycycline was prescribed in a small number of patients, a favorable outcome was observed in all cases.

    Acute rheumatic fever and rheumatic chronic valvular heart disease is an important preventable cause of morbidity and mortality in suburban and rural India. Its diagnosis is based on clinical criteria. These criteria need verification and revision in the Indian context. Furthermore, there are glaring differences in management protocols available in literature. These facts prompted Indian Academy of Pediatrics to review the management of rheumatic fever. Management of Rheumatic fever was reviewed and recommendation was formulated at national consultative meeting on 20th May 2007 at New Delhi. To formulate uniform guidelines on management of acute rheumatic fever and rheumatic heart disease in the Indian context. Guidelines were formulated for the management of streptococcal pharyngitis, acute rheumatic fever and its cardiac complication as well as secondary prophylaxis for recurrent episodes. (1) Streptococcal eradication with appropriate antibiotics (Benzathine penicillin single dose or penicillin V oral or azithromycin). (2) Diagnosis of rheumatic fever based on Jones criteria. (3) Control inflammatory process with aspirin with or without steroids (total duration of treatment of 12 weeks). (4) Treatment of chorea according to severity (therapy to continue for 2-3 weeks after clinical improvement). (5) Protocol for managing cardiac complication like valvular heart disease, congestive heart failure and atrial fibrillation. (6) Secondary prophylaxis with benzathine penicillin and management of anaphylaxis.

    Full Text Available OBJECTIVE: To study etiology, risk factors, various clinical and lab parameters and outcome of patients presenting with fever, jaundice and acute kidney injury. MATERIALS AND METHODS : An open prospective study was done on 100 patients presented with triad of fever, jaundice and acute kidney injury (AKI in the Depar tment of Medicine of G R Medical College and JA Group of Hospitals, Gwalior, MP from September 2011 to November 2012. Patients having temperature more than >100 0 F, serum creatinine ≥1.3 mg/dL or a 50 % increase from baseline or a reduction in urine output (documented oliguria of 6 hours, serum bilirubin >1.8 mg/dL were included in the study. A detailed history, clinical examination and investigations were done to find the cause of these derangements and all the patients were managed acc ordingly. RESULTS: A total 100 patients were included in study out of which 70% were males. Out of 100 patients, 50% were of septicemia, 34% were having malaria, 12% had acute pancreatitis and 4% patients were of dengue. Out of 50 septicemia patients, 35(7 0% were male, out of which 11(31.42% were of 56 - 65 years of age. Out of 17 deaths, 13(76% were males. Among total death, 11(22% were in septicemia followed by 5(14.70% in malaria patients. CONCLUSION: Many infectious and non - infectious diseases like malaria, septicemia, acute pancreatitis, dengue fever etc. can present with fever, jaundice and deranged renal functions. This triad of presentation is associated wi th high morbidity and mortality and the advanced age, male gender presences of anemia were the risk factors for high mortality. AKI occurs most commonly in association with P. falciparum malaria. Early diagnosis and prompt management including dialysis can reduce mortality and expedite recovery of renal function

    Acute rheumatic fever remains a serious healthcare concern for the majority of the world's population despite its decline in incidence in Europe and North America. The goal of this statement was to review the historic Jones criteria used to diagnose acute rheumatic fever in the context of the current epidemiology of the disease and to update those criteria to also take into account recent evidence supporting the use of Doppler echocardiography in the diagnosis of carditis as a major manifestation of acute rheumatic fever. To achieve this goal, the American Heart Association's Council on Cardiovascular Disease in the Young and its Rheumatic Fever, Endocarditis, and Kawasaki Disease Committee organized a writing group to comprehensively review and evaluate the impact of population-specific differences in acute rheumatic fever presentation and changes in presentation that can result from the now worldwide availability of nonsteroidal anti-inflammatory drugs. In addition, a methodological assessment of the numerous published studies that support the use of Doppler echocardiography as a means to diagnose cardiac involvement in acute rheumatic fever, even when overt clinical findings are not apparent, was undertaken to determine the evidence basis for defining subclinical carditis and including it as a major criterion of the Jones criteria. This effort has resulted in the first substantial revision to the Jones criteria by the American Heart Association since 1992 and the first application of the Classification of Recommendations and Levels of Evidence categories developed by the American College of Cardiology/American Heart Association to the Jones criteria. This revision of the Jones criteria now brings them into closer alignment with other international guidelines for the diagnosis of acute rheumatic fever by defining high-risk populations, recognizing variability in clinical presentation in these high-risk populations, and including Doppler echocardiography as a tool

    Full Text Available Occupational inhalation exposure to noxious agents is not uncommon. Herein, we present a 26-year-old male student who had accidental acute inhalation exposure to a large quantity of titanium ethanolate and hydrogen chloride in chemistry lab. He was referred to the emergency department of our hospital with low-grade fever, dyspnea, headache, fatigue and myalgia. After 24 hrs of symptomatic treatment (oxygen therapy and acetaminophen, the fever was subsided and the patient discharged home in a good clinical condition. The presented symptoms could be interpreted as a form of metal fume fever. It can therefore be concluded that organo-metallic compound of titanium metal may have the potential to produce metal fume fever in human.

    Full Text Available Background: Acute undifferentiated fever (AUF is a common cause for which the patients seek health care in India. It is region specific and has similar clinical presentation, with varied etiologies. Due to this it posses challenge to the diagnosis, treatment and public health. Majority of patients present with nondescript symptoms. Scrub typhus, Malaria, Enteric Fever, Dengue, Leptospirosis, Chikungunya, Spotted fever, Rickettsiosis, Hantavirus, Q fever, Brucellosis, Influenza and other bacterial infections are some of the common etiologies of AUF. The prevalence of local AUF etiologies helps to prioritize differential diagnosis and guide the treatment. The study aimed to find out the predominant AUF etiologies in the rural Konkan area of Maharashtra state in India. Materials and Methods: This prospective observational study was conducted at a tertiary care hospital on the samples received from District hospitals and Primary health centers from Sindhudurg District of Maharashtra state for the duration of October 2012 to January 2014. Patients with age 5years and with classical symptoms of febrile illness were included in the study. About 500 blood samples received were investigated for Malaria, Bacterial culture sensitivity, Leptospira culture, ELISA for scrub typhus, Brucella, Dengue and Leptospira and further evaluated for commonest region specific AUF etiology. Results: The study included 500 blood samples obtained from patients presenting with classical symptoms of AUF. Samples received from males showed highest number of positive cases amounting for 82.47% with majority of cases (83% cases in middle age group. The sero-positivity of samples accounted for 42.8%. Brucella was the most common cause of AUF (28.50% followed by Leptospira (27.10% and Scrub typhus (21.49%. Interestingly there were no positive cases of malaria and only 11.21% samples positive for Dengue which are considered as most common AUF etiologies and treated accordingly

    Dengue fever is the most important arbovirus illness with an estimated incidence of 50-100 million cases per year. The common symptoms of dengue include fever, rash, malaise, nausea, vomiting, and musculoskeletal pain. Dengue fever may present as acute abdomen leading to diagnostic dilemma. The acute surgical complications of dengue fever include acute pancreatitis, acute acalculous cholecystitis, nonspecific peritonitis, and acute appendicitis. We report a case of dengue fever that mimicked acute appendicitis leading to unnecessary appendectomy. A careful history examination for dengue-related signs, and serial hemogram over the first 3-4 days of disease may prevent unnecessary appendectomy.

    The incidence of in-hospital cases of acute rheumatic fever in residents of the San Fernando Valley section of Los Angeles (population 1,096,000) from 1971 through 1980 was 0.21 per 100,000 population for all ages and 0.63 per 100,000 for 5 to 17 year olds, both among the lowest ever reported in the world literature. Nevertheless, minority group patients had five times the risk of a white patient for acute rheumatic fever developing and a greater than 20-fold increase in the risk for the development of acute rheumatic fever with carditis. Unexpectedly, a low 30% of cases (8/27) had carditis either alone or with other major criteria, while a high 59% (16/27) had polyarthritis as the only major manifestation. This suggests the possibility of false-positive cases based on polyarthritis as the only major manifestation, and that an incidence of acute rheumatic fever may have been reached that is so low that “background” cases are a significant proportion of all cases.

    The objectives of this study were to determine the proportion of malaria, bacteraemia, scrub typhus, leptospirosis, chikungunya and dengue among hospitalized patients with acute undifferentiated fever in India, and to describe the performance of standard diagnostic methods. During April 2011-November 2012, 1564 patients aged ≥5 years with febrile illness for 2-14 days were consecutively included in an observational study at seven community hospitals in six states in India. Malaria microscopy, blood culture, Dengue rapid NS1 antigen and IgM Combo test, Leptospira IgM ELISA, Scrub typhus IgM ELISA and Chikungunya IgM ELISA were routinely performed at the hospitals. Second line testing, Dengue IgM capture ELISA (MAC-ELISA), Scrub typhus immunofluorescence (IFA), Leptospira Microscopic Agglutination Test (MAT), malaria PCR and malaria immunochromatographic rapid diagnostic test (RDT) Parahit Total™ were performed at the coordinating centre. Convalescence samples were not available. Case definitions were as follows: Leptospirosis: Positive ELISA and positive MAT. Scrub typhus: Positive ELISA and positive IFA. Dengue: Positive RDT and/or positive MAC-ELISA. Chikungunya: Positive ELISA. Bacteraemia: Growth in blood culture excluding those defined as contaminants. Malaria: Positive genus-specific PCR. Malaria was diagnosed in 17% (268/1564) and among these 54% had P. falciparum. Dengue was diagnosed in 16% (244/1564). Bacteraemia was found in 8% (124/1564), and among these Salmonella typhi or S. paratyphi constituted 35%. Scrub typhus was diagnosed in 10%, leptospirosis in 7% and chikungunya in 6%. Fulfilling more than one case definition was common, most frequent in chikungunya where 26% (25/98) also had positive dengue test. Malaria and dengue were the most common causes of fever in this study. A high overlap between case definitions probably reflects high prevalence of prior infections, cross reactivity and subclinical infections, rather than high prevalence of

    The role of prodromal fever in the clinical course of acute hepatitis B virus (HBV) infection is still largely unclear. This study was conducted to investigate the factors associated with prodromal fever and its role in the development of acute liver failure (ALF) in patients with acute hepatitis B (AHB). Inpatients with AHB diagnosed between January 2006 and December 2010 were evaluated and followed. Clinical manifestations, results of laboratory tests, and outcomes were compared between patients with and without prodromal fever. The diagnosis of AHB was based on the discrete onset of symptoms, jaundice, abnormal liver function tests, the detection of high-titer IgM antibody to hepatitis B core antigen (anti-HBc), and a compatible clinical history. A total of 618 AHB inpatients were identified during the study period, of whom 102 (16.5%) had prodromal fever and 41 (6.6%) developed ALF. Prodromal fever indicated more severe liver injury and was independently associated with hepatitis B e antigen (HBeAg) negativity. The occurrence of ALF was more common in febrile patients than in non-febrile patients (18.6% vs. 4.3%, pfever and temperature >38.0°C to be independently associated with the risk of ALF, with an odds ratio (95% confidence interval) of 3.5 (1.4-8.6) and 7.1 (2.6-19.7), respectively. AHB patients with prodromal fever, which is associated with a lack of HBeAg due to HBV mutation, are at high risk of ALF. Febrile patients with AHB should be managed with particular care.

    Ocular manifestations of the dengue fever virus include bilateral panuveitis that can occur after the acute systemic infection has resolved. In most reported cases, the inflammation resolves with topical or systemic steroid therapy. We report a case of chronic, refractory bilateral panuveitis and uveitic glaucoma that began during the acute phase of the systemic infection and required treatment with oral steroids, multiple steroid-sparing agents, and surgical therapy for glaucoma. A 22-year-old male with acute systemic dengue fever presented with bilateral pain and decreased vision. Clinical examination revealed bilateral panuveitis with elevated intraocular pressures. Management required oral steroids, mycophenolate mofetil, cyclosporine, and bilateral glaucoma valve implantation. This case highlights the fact that dengue-associated panuveitis can begin in the acute stage of systemic infection and persist long after convalescence with progression to chronic bilateral panuveitis and uveitic glaucoma. Dengue-associated chronic panuveitis with uveitic glaucoma may be effectively managed with a combination of steroid-sparing oral immunosuppression and glaucoma surgery. This is, to our knowledge, the first case of bilateral refractory dengue-associated panuveitis from the Caribbean treated with combination steroid-sparing oral immunosuppression and bilateral glaucoma valve implantation.

    Acute rheumatic fever (ARF) is an autoimmune, multi-system response secondary to molecular mimicry following Lancefield group A streptococcus (GAS) pharyngitis; it is now most commonly found in the pediatric populations of developing nations. The major source of morbidity and mortality of ARF stems from rheumatic heart disease (RHD), although the cardinal symptoms of the disease also include polyarthritis, Sydenham's chorea, subcutaneous nodules, and erythema marginatum. Therapy is aimed towards treating the initial GAS infection, using anti-inflammatory medications for acute symptoms and surgery to correct RHD. Secondary prevention is crucial, given the high risk of recurrence, and includes long-term antibiotic prophylaxis. However, vaccination towards GAS may soon be on the horizon, which may assist in both decreasing the risk of initial infection in naïve patients and helping to lower the risk of recurrence.

    Dengue fever (DF) is a relatively common infection in travelers, with about 100 cases being reported annually in Japan, and this number is increasing. We herein describe two patients who developed a fever after returning to Japan from Southeast Asia and who were serologically diagnosed with DF. Patient 1 was a 19-year-old man who spent 6 days in Thailand and developed diarrhea and a fever after returning to Japan. Virological studies showed dengue virus (DV) serotype 3 by reverse transcriptase PCR (RT-PCR), and anti-DV IgM and IgG antibodies were both positive by enzyme-linked immunosorbent assay (ELISA). Patient 2 was a 43-year-old man who spent time in various Asian countries and developed a fever and arthralgia after returning to Japan. Virological studies showed DV serotype 2 by RT-PCR, and anti-DV IgM and IgG antibodies were both positive by ELISA. DF and other febrile diseases, including Chikungunya fever, should be strongly suspected in patients who develop fever after returning to Japan from other Asian countries, irrespective of whether patients remember being bitten by mosquitoes.

    Ten of twelve men who participated in the cleaning of an electric power steam turbine condenser clogged with freshwater sponge experienced an acute febrile illness. Two similar outbreaks have been previously described, one of which has been attributed to the Legionnaires' Disease bacterium. Epidemiologic studies of this case showed a syndrome very similar to the two previously reported episodes. However, the exact etiology for this outbreak has not been identified. Environmental sampling was not initiated until after the cleaning was completed. Subsequent testing did not reveal any likely cause for the outbreak. The delayed onset of symptoms and the nature of the illness pointed to an infectious agent. In the absence of any suitable criteria for employee exposure evaluation, it is suggested that crews cleaning condensers under unusually dirty conditions, especially if eye or respiratory symptoms are reported, should be provided with respiratory protection.

    To describe new developments (2013-2014) in acute rheumatic fever (ARF) and rheumatic heart disease (RHD) relevant to developing countries. Improved opportunities for the primary prevention of ARF now exist, because of point-of-care antigen tests for Streptococcus pyogenes, and clinical decision rules which inform management of pharyngitis without requiring culture results. There is optimism that a vaccine, providing protection against many ARF-causing S. pyogenes strains, may be available in coming years. Collaborative approaches to RHD control, including World Heart Federation initiatives and the development of registers, offer promise for better control of this disease. New data on RHD-associated costs provide persuasive arguments for better government-level investment in primary and secondary prevention. There is expanding knowledge of potential biomarkers and immunological profiles which characterize ARF/RHD, and genetic mutations conferring ARF/RHD risk, but as yet no new diagnostic testing strategy is ready for clinical application. Reduction in the disease burden and national costs of ARF and RHD are major priorities. New initiatives in the primary and secondary prevention of ARF/RHD, novel developments in pathogenesis and biomarker research and steady progress in vaccine development, are all causes for optimism for improving control of ARF/RHD, which affect the poorest of the poor.

    Full Text Available Abstract Background Hyperglycaemia, fever, and swallowing dysfunction are poorly managed in the admission phase of acute stroke, and patient outcomes are compromised. Use of evidence-based guidelines could improve care but have not been effectively implemented. Our study aims to develop and trial an intervention based on multidisciplinary team-building to improve management of fever, hyperglycaemia, and swallowing dysfunction in patients following acute stroke. Methods and design Metropolitan acute stroke units (ASUs located in New South Wales, Australia will be stratified by service category (A or B and, within strata, by baseline patient recruitment numbers (high or low in this prospective, multicentre, single-blind, cluster randomised controlled trial (CRCT. ASUs then will be randomised independently to either intervention or control groups. ASUs allocated to the intervention group will receive: unit-based workshops to identify local barriers and enablers; a standardised core education program; evidence-based clinical treatment protocols; and ongoing engagement of local staff. Control group ASUs will receive only an abridged version of the National Clinical Guidelines for Acute Stroke Management. The following outcome measures will be collected at 90 days post-hospital admission: patient death, disability (modified Rankin Score; dependency (Barthel Index and Health Status (SF-36. Additional measures include: performance of swallowing screening within 24 hours of admission; glycaemic control and temperature control. Discussion This is a unique study of research transfer in acute stroke. Providing optimal inpatient care during the admission phase is essential if we are to combat the rising incidence of debilitating stroke. Our CRCT will also allow us to test interventions focussed on multidisciplinary ASU teams rather than individual disciplines, an imperative of modern hospital services.

    Full Text Available Dengue viral infections have become one of major emerging infectious diseases in the tropics. Acute abdomen occurring in dengue viral infection is not uncommon. The spectrums of acute surgical emergencies which raise suspicion of an abdominal catastrophe in patients presenting with dengue fever include acute pancreatitis, acute acalculous cholecystitis, non-specific peritonitis and very rarely acute appendicitis. The presence of low white cell count and platelet count can raise suspicion of a diagnosis of dengue in a patient presenting with acute abdominal pain, during a dengue epidemic. We herein report three patients with dengue fever who had appendicular perforation during the course of their viral fever.

  8. Review of the risks and benefits of yellow fever vaccination including some new analyses.

    The live, attenuated yellow fever (YF) 17D vaccine provides highly effective and durable immunity and is widely used for travelers to and residents of endemic areas of South America and Africa. Neurotropic and viscerotropic serious adverse events associated with these vaccines occur rarely, but YF 17D vaccine-associated viscerotropic disease (YEL-AVD) is notable for its lethality. There appear to be two distinct patterns of risk for YEL-AVD: the first in younger persons, particularly women, with defects in innate immunity, in whom the case-fatality rate is higher; and the second in elderly persons, particularly men with age-related immune senescence and a lower case-fatality rate. From 1990 to the present, the number of cases (n = 31) and deaths (n = 12) from YEL-AVD in travelers has exceeded the reports of YF (n = 6) acquired by natural infection, raising the question whether the risk of vaccination exceeds the benefit in travelers. To provide some guidance on this point, the rate of vaccine-related injury is compared with the rate of naturally acquired disease in a new analysis that estimates the immunologically susceptible denominator population in YF endemic and epidemic areas. For many years, the risk of vaccine-related illness and death was similar to the risk of illness and death from natural infection with YF in South America. Africa posed a substantially higher estimated risk of wild-type YF than vaccine-related injury. Multiple factors should be considered in making decisions about YF vaccination, including specific destination, season of the year, local evidence for YF transmission, likelihood of exposure to vector mosquitoes and individual risk factors for YEL-AVD, with the goal of increasing vaccine coverage for travel to high-risk areas and reducing unnecessary vaccination. Prospects for future, safer vaccines are also described.

    Dengue is a common arboviral infection with a clinically diverse spectrum of presentations. Although hepatic dysfunction is commonly identified in patients will dengue illness, acute liver failure is rare. The etiopathogenesis of hepatic dysfunction is multifactorial and related to direct viral invasion of hepatocytes, immunological factors and hypoxia particularly in cases of shock in dengue hemorrhagic fever. Ideal management of dengue-related hepatic dysfunction and acute liver failure is still debated. We report a 53-year-old Sri Lankan Sinhalese male with serologically confirmed dengue fever presenting with evidence of plasma leakage developing acute liver failure evidenced by deranged liver functions, coagulopathy and altered sensorium. In addition to the 'standard care', the patient was managed with intravenous N-acetyl cysteine and blood transfusions even in the absence of bleeding or dropping packed cell volume (PCV), targeting a higher PCV in anticipation of better oxygenation at tissue level. He made a full recovery with no sequential infections. N-acetyl cysteine and packed cell transfusion aiming at a higher PCV to maintain adequate tissue perfusion during shock may be beneficial in acute liver failure due to dengue virus. Large randomized trials should be carried out to establish the efficacy of these treatment strategies to support these observations and change the current practice.

    To evaluate the cerebral and hemodynamic effects of low-dose intramuscular diclofenac sodium (DCFS) administered for fever control in patients with acute brain injury in the intensive care unit. Inclusion criteria for this prospective clinical study were age ≥18 years; the ability to monitor intra-arterial blood pressure, core body temperature, and intracranial pressure; the placement of an indwelling jugular venous catheter for intermittent jugular venous oxygen saturation measurements; and a core body temperature ≥37.5°C. Exclusion criteria were hypovolemia, administration of drugs with hemodynamic effects during the study period, administration of antipyretics within 6 hours before the start of the study, acute heart failure, cerebral vasospasm, pregnancy, renal and gastric diseases, and allergy to DCFS. The study enrolled 30 patients with acute brain injury. Two We observed statistically significant decreases in core body temperature (P administration with respect to baseline (T0). The dosage of noradrenaline (norepinephrine) in subjects receiving treatment at the start of the study increased significantly from 0.14 μg/kg/minute ± 0.1 to 0.20 μg/kg/minute ± 0.1 (P = 0.0395). Low-dose intramuscular DCFS administration for fever control in patients with acute brain injury is effective but also exposes patients to potentially deleterious hypotensive episodes that must be diagnosed and treated expeditiously to prevent further damage to the injured brain.

    Full Text Available Serologic diagnosis is one of the most widely used diagnostic methods for Q fever, but the window period in antibody response of 2 to 3 weeks after symptom onset results in significant diagnostic delay. We investigated the diagnostic utility of Q fever PCR from formalin-fixed liver tissues in Q fever patients with acute hepatitis.We reviewed the clinical and laboratory data in patients with Q fever hepatitis who underwent liver biopsy during a 17-year period, and whose biopsied tissues were available. We also selected patients who revealed granuloma in liver biopsy and with no Q fever diagnosis within the last 3 years as control. Acute Q fever hepatitis was diagnosed if two or more of the following clinical, serologic, or histopathologic criteria were met: (1 an infectious hepatitis-like clinical feature such as fever (≥ 38°C with elevated hepatic transaminase levels; (2 exhibition of a phase II immunoglobulin G (IgG antibodies titer by IFA of ≥ 1:128 in single determination, or a four-fold or greater rise between two separate samples obtained two or more weeks apart; (3 histologic finding of biopsy tissue showing characteristic fibrin ring granuloma.A total of 11 patients with acute Q fever hepatitis were selected and analyzed. Of the 11 patients, 3 (27% had exposure to zoonotic risk factors and 7 (63% met the serologic criteria. Granulomas with either circumferential or radiating fibrin deposition were observed in 10 cases on liver biopsy and in 1 case on bone marrow biopsy. 8 (73% revealed positive Coxiella burnetii PCR from their formalin-fixed liver tissues. In contrast, none of 10 patients with alternative diagnosis who had hepatic granuloma revealed positive C. burnetii PCR from their formalin-fixed liver tissues.Q fever PCR from formalin-fixed liver tissues appears to be a useful adjunct for diagnosing Q fever hepatitis.

    Acute pancreatitis is one of the rare complications of hemorrhagic fever with renal syndrome (HFRS), which easy to be misdiagnosed as acute abdomen, usually critically ill, poor treatment effect, highly mortality. In this study, we retrospectively analyzed to explore the clinical characteristics, 12 cases of hemorrhagic fever with renal syndrome complicated with acute pancreatitis treatment methods and prognosis. We conducted a retrospective study of HFRS in patients complicated with acute pancreatitis. 12 cases were collected from Ningbo first hospital between January 2001 and December 2012. Clinical information and laboratory parameters were obtained by reviewing literature and records. Twelve from 156 cases (7.69%) HFRS complicated with acute pancreatitis. Men comprised more than half (75%) of the sample population, the mean age was (38 ± 19) years. Abdominal pain was the main clinical manifestations in all the patients, all of their serum amylase and serum lipase were increased, 10 patients were given the total abdomen CT examination, eight cases showed enlargement of the pancreas and surrounding leakage, two cases showed pancreatic necrosis and hemorrhage. Three cases complicated with pulmonary edema. In 12 cases, four of them received hemodialysis treatment, one gives surgical intervention. Eight cases were complete remission, three cases were partial remission and one case was death. Acute pancreatitis is one of rare of the serious complications of HFRS, whereas the correct diagnosis and clear the cause of disease is critical for improve the quality of life of patients and reduce the mortality, timely hemodialysis treatment is effective, early intervention can improve the prognosis.

    Full Text Available Acute renal failure (ARF is reported in some severe forms of malaria such as black water fever (BWF. It is associated with a high mortality rate and can be managed effectively with adequate renal replacement. A prospective survey of children with dark urine after a malarial infection with Plasmodium falciparum was coupled with a chart review study of patients managed in the past 11 years in the Pediatrics′ Kinshasa University Hospital. Eighty-nine cases of ARF were identified, but data from only 63 patients were available, of whom 44 (69.8% had severe malaria (39 with BWF and 5 with cerebral malaria. The mean age of the patients was 8.2 ± 1.73 years. Of the 39 cases of BWF, an association with quinine ingestion was observed in 32 children (82%. Urea and creatinine levels were elevated in all cases (135.4 ± 88.2 and 3.83 ± 2.81 mg/dL, respectively. Oligo-anuria was observed in 44.4%, severe metabolic acidosis (bicarbonate <15 mEq/L in 61.5% and hyponatremia (<130 mEq/L in 33.3%. Peritoneal dialysis was required in 36 patients, including 20 with BWF. The remaining patients were managed with conservative treatment. Twenty-eight children (44.4%, including 20 on dialysis, fully recovered and 14 died (22.2%, including eight cases of BWF. Our study suggests that ARF is commonly associated with BWF in Congolese children. Elevated urea and creatinine and severe metabolic acidosis were observed more often than other clinical/metabolic disturbances. Severe renal impairment remains a significant complication with a high mortality rate in low-resource settings.

    Fluoroquinolones reduce occurrence of fever in adult cancer patients who develop neutropenia, but there has been no randomized controlled trial in children, and there are only a few studies considering resistance in intestinal floral after ciprofloxacin has been used. Children younger than 18 years with acute lymphoblastic leukemia or lymphoma scheduled to undergo chemotherapy were randomized to receive oral ciprofloxacin 20mg/kg/day or placebo from the beginning of their chemotherapy. Rectal swab cultures were taken before and at 1 and/or 2 weeks after the intervention. Of the total of 95 patients, 45 and 50 patients received ciprofloxacin and placebo, respectively. Of the 71 patients who developed neutropenia, the proportion of children who developed fever was significantly lower in the ciprofloxacin group than in the placebo group (17/34 [50.0%] versus 27/37 [73.0%]; absolute difference in risk, -23.0%; 95% confidence interval: -45.0% to -0.9%; P = 0.046). Ciprofloxacin significantly reduced the occurrence of febrile episodes in patients with acute lymphoblastic leukemia in the induction phase of chemotherapy, but not in patients with lymphoma or in the consolidation phase of chemotherapy. Adverse effects were not different between the groups. After intervention, the percentages of Escherichia coli and Klebsiella pneumoniae susceptible to ciprofloxacin were significantly lower in the ciprofloxacin group. Ciprofloxacin can prevent fever in neutropenic patients with acute lymphoblastic leukemia during the induction phase of chemotherapy with good tolerance and no serious side effects. Due to the selective pressure of intestinal flora resistance to ciprofloxacin, the long-term effectiveness needs further investigation.

    Full Text Available Acute rheumatic fever (ARF is an inflammatory collagenous tissue disease which shows its cardinal signs in joints, heart, skin and nervous system while affecting whole connective tissue system more or less. This study was conducted in order to investigate the clinical pattern and severity of ARF, echocardiographic findings and the course of the patients with heart valve involvement by studying the clinical and laboratory aspects of the patients diagnosed with ARF according to updated Jones criteria. The study included 214 patients diagnosed with ARF for the first time between January 2005 and May 2008. All patients were scanned with doppler echocardiography (ECHO between certain intervals. Severity of carditis was grouped into 3 groups of mild, moderate and severe. The frequency of carditis was 57.9%, arthritis was 73.4%, chorea was 11.7% and erythema marginatum was 0.9% but no subcutaneous nodules. Recovery was observed in 22% of the cases of isolated aortic insufficiency (AI, 50% of the cases with isolated mitral insufficiency (MI and 80% of the cases with mitral and aortic insufficiencies together (MI+AI. Recovery in isolated MI was significantly much more than recovery in isolated AI. However, recovery in AI was significantly much more than in MI in cases of mitral and aortic insufficiencies together. In conclusion, ARF is a cause of acquired and preventable heart disease and it can be reversed through right diagnosis and appropriate treatment. Isolated mitral insufficiency, isolated aortic insufficiency and both mitral and aortic insufficiency are observed during a valvular disease. Remission among valvular diseases are most commonly in those with mitral insufficiency and remissions in both mitral and aortic insufficiency occur most commonly in aortic ones. Regular prophylaxis is the key element for long term prevention of patients with ARF.

  17. Acute Cholecystitis as a Cause of Fever in Aneurysmal Subarachnoid Hemorrhage

    Na Rae Yang

    2017-05-01

    Full Text Available Background Fever is a very common complication that has been related to poor outcomes after aneurysmal subarachnoid hemorrhage (aSAH. The incidence of acalculous cholecystitis is reportedly 0.5%–5% in critically ill patients, and cerebrovascular disease is a risk factor for acute cholecystitis (AC. However, abdominal evaluations are not typically performed for febrile patients who have recently undergone aSAH surgeries. In this study, we discuss our experiences with febrile aSAH patients who were eventually diagnosed with AC. Methods We retrospectively reviewed 192 consecutive patients who underwent aSAH from January 2009 to December 2012. We evaluated their characteristics, vital signs, laboratory findings, radiologic images, and pathological data from hospitalization. We defined fever as a body temperature of >38.3°C, according to the Society of Critical Care Medicine guidelines. We categorized the causes of fever and compared them between patients with and without AC. Results Of the 192 enrolled patients, two had a history of cholecystectomy, and eight (4.2% were eventually diagnosed with AC. Among them, six patients had undergone laparoscopic cholecystectomy. In their pathological findings, two patients showed findings consistent with coexistent chronic cholecystitis, and two showed necrotic changes to the gall bladder. Patients with AC tended to have higher white blood cell counts, aspartame aminotransferase levels, and C-reactive protein levels than patients with fevers from other causes. Predictors of AC in the aSAH group were diabetes mellitus (odds ratio [OR], 8.758; P = 0.033 and the initial consecutive fasting time (OR, 1.325; P = 0.024. Conclusions AC may cause fever in patients with aSAH. When patients with aSAH have a fever, diabetes mellitus and a long fasting time, AC should be suspected. A high degree of suspicion and a thorough abdominal examination of febrile aSAH patients allow for prompt diagnosis and treatment of this

    Joint pain and raised inflammatory markers are features of both acute rheumatic fever (ARF) and septic arthritis, often posing a diagnostic challenge to clinicians. Important differences in the presenting serological inflammatory marker profile may assist patient diagnosis, however, as clinical experience suggests that ARF is associated with a higher erythrocyte sedimentation rate (ESR), whereas other serological markers may be similarly elevated in these 2 conditions. The goal of this study was to determine the diagnostic value of serological inflammatory markers and white cell count (WCC) in children presenting with acute joint pain secondary to ARF or septic arthritis. Data were obtained from the Auckland regional rheumatic fever database and hospital computer records between 2005 and 2012. Records of all patients under the age of 16 years who were admitted with a new diagnosis of ARF or septic arthritis were analyzed. The diagnosis of ARF was defined on the basis of the New Zealand modification of the Jones Criteria, and the diagnosis of septic arthritis was defined on the basis of joint fluid cytology and culture. Baseline characteristics, serological inflammatory markers, and serum WCC were compared between the ARF and septic arthritis patient groups. Children with ARF displayed significantly higher ESR, higher serum C-reactive protein, and lower serum WCC than children with septic arthritis on presentation to hospital. In children presenting with monoarthritis, an ESR>64.5, serum WCCseptic arthritis. A significant proportion (30%) of children with the final diagnosis of ARF initially presented with monoarthritis; 14% of these children (5/34) had received nonsteroidal anti-inflammatory medication before hospital presentation, and 74% of these children (25/34) had abnormal echocardiograms on admission. ARF and septic arthritis are important diagnoses to consider in children presenting with acute joint pain in New Zealand. A significant proportion of patients

    To determine whether dental caries, as an indicator of cumulative exposure to sugar, is associated with the incidence of acute rheumatic fever and chronic rheumatic heart disease, in Māori and Pacific children aged 5 and 6 years at their first dental visit. A cohort study was undertaken which linked school dental service records of caries with national hospital discharge and mortality records. Cox models were used to investigate the strength of the association between dental caries and rheumatic fever incidence. A total of 20 333 children who were free of rheumatic heart disease at enrolment were available for analysis. During a mean follow-up time of 5 years, 96 children developed acute rheumatic fever or chronic rheumatic heart disease. After adjustment for potential confounders, children with five or more primary teeth affected by caries were 57% (95% CI: 20% to 106%) more likely to develop disease during follow-up, compared to children whose primary teeth were caries free. The population attributable to the risk for caries in this cohort was 22%. Dental caries is positively associated with the incidence of acute rheumatic fever and chronic rheumatic heart disease in Māori and Pacific children. Sugar intake, an important risk factor for dental caries, is also likely to influence the aetiology of rheumatic fever. Published by the BMJ Publishing Group Limited.

  2. The incidence of acute rheumatic fever in a suburban area of Los Angeles. A ten-year study.

    Science.gov (United States)

    Odio, A

    1986-02-01

    The incidence of in-hospital cases of acute rheumatic fever in residents of the San Fernando Valley section of Los Angeles (population 1,096,000) from 1971 through 1980 was 0.21 per 100,000 population for all ages and 0.63 per 100,000 for 5 to 17 year olds, both among the lowest ever reported in the world literature. Nevertheless, minority group patients had five times the risk of a white patient for acute rheumatic fever developing and a greater than 20-fold increase in the risk for the development of acute rheumatic fever with carditis. Unexpectedly, a low 30% of cases (8/27) had carditis either alone or with other major criteria, while a high 59% (16/27) had polyarthritis as the only major manifestation. This suggests the possibility of false-positive cases based on polyarthritis as the only major manifestation, and that an incidence of acute rheumatic fever may have been reached that is so low that "background" cases are a significant proportion of all cases.

    The indirect immunofluorescence assay (IFA) is considered the reference method for diagnosing Q fever, but serology is also performed by complement fixation assay (CFA) or enzyme-linked immunosorbent assay (ELISA). However, comparability between these assays is not clear, and therefore a quality assessment was performed. A total of 25 serum samples from negative controls, Q fever patients, and a serial diluted high-positive sample were analyzed in 10 Dutch laboratories. Six laboratories performed CFA, 5 performed IFA, and 5 performed ELISAs. Three international reference laboratories from Australia, France, and the USA also participated in this study. Qualitative values between laboratories using the same methods were within close range, and all 3 methods correctly identified acute Q fever patients. The IFA, ELISA, and CFA are all suitable serodiagnostic assays to diagnose acute Q fever, but the IFA remains an important tool in the follow-up of patients and in identifying patients at risk for developing chronic Q fever.

    Dengue fever is an acute febrile illness with a duration of 2-12 days. Our observational study observed the 24-h continuous tympanic temperature pattern of 15 patients with dengue fever and compared this with 26 others with fever due to a non-dengue aetiology. A tri-phasic fever pattern was seen among two-thirds of dengue fever patients, but in only one with an inflammatory disease. One-third of dengue fever patients exhibited a single peak temperature. Continuous temperature monitoring and temperature pattern analysis in clinical settings can aid in the early differentiation of dengue fever from non-dengue aetiology.

    Acute rheumatic fever (ARF), a sequelae of group A Streptococcus (GAS) infection, is the most common cause of preventable childhood heart disease worldwide. The molecular basis of ARF and the subsequent rheumatic heart disease are poorly understood. Serotype M18 GAS strains have been associated for decades with ARF outbreaks in the U.S. As a first step toward gaining new insight into ARF pathogenesis, we sequenced the genome of strain MGAS8232, a serotype M18 organism isolated from a patient with ARF. The genome is a circular chromosome of 1,895,017 bp, and it shares 1.7 Mb of closely related genetic material with strain SF370 (a sequenced serotype M1 strain). Strain MGAS8232 has 178 ORFs absent in SF370. Phages, phage-like elements, and insertion sequences are the major sources of variation between the genomes. The genomes of strain MGAS8232 and SF370 encode many of the same proven or putative virulence factors. Importantly, strain MGAS8232 has genes encoding many additional secreted proteins involved in human-GAS interactions, including streptococcal pyrogenic exotoxin A (scarlet fever toxin) and two uncharacterized pyrogenic exotoxin homologues, all phage-associated. DNA microarray analysis of 36 serotype M18 strains from diverse localities showed that most regions of variation were phages or phage-like elements. Two epidemics of ARF occurring 12 years apart in Salt Lake City, UT, were caused by serotype M18 strains that were genetically identical, or nearly so. Our analysis provides a critical foundation for accelerated research into ARF pathogenesis and a molecular framework to study the plasticity of GAS genomes.

    Acute renal failure (ARF) is reported in some severe forms of malaria such as black water fever (BWF). It is associated with a high mortality rate and can be managed effectively with adequate renal replacement. A prospective survey of children with dark urine after a malarial infection with Plasmodium falciparum was coupled with a chart review study of patients managed in the past 11 years in the Pediatrics' Kinshasa University Hospital. Eighty-nine cases of ARF were identified, but data from only 63 patients were available, of whom 44 (69.8%) had severe malaria (39 with BWF and 5 with cerebral malaria). The mean age of the patients was 8.2±1.73 years. Of the 39 cases of BWF, an association with quinine ingestion was observed in 32 children (82%). Urea and creatinine levels were elevated in all cases (135.4±88.2 and 3.83±2.81 mg/dL, respectively). Oligo-anuria was observed in 44.4%, severe metabolic acidosis (bicarbonatemetabolic acidosis were observed more often than other clinical/metabolic disturbances. Severe renal impairment remains a significant complication with a high mortality rate in low-resource settings.

  9. Serological Evidence of Immune Priming by Group A Streptococci in Patients with Acute Rheumatic Fever

    2016-07-01

    Full Text Available Acute rheumatic fever (ARF is an autoimmune response to Group A Streptococcus (GAS infection. Repeated GAS exposures are proposed to ‘prime’ the immune system for autoimmunity. This notion of immune-priming by multiple GAS infections was first postulated in the 1960s, but direct experimental evidence to support the hypothesis has been lacking. Here we present novel methodology, based on antibody responses to GAS T‑antigens, that enables previous GAS exposures to be mapped in patient sera. T-antigens are surface expressed, type specific antigens and GAS strains fall into 18 major clades or T-types. A panel of recombinant T-antigens was generated and immunoassays were performed in parallel with serum depletion experiments allowing type-specific T‑antigen antibodies to be distinguished from cross-reactive antibodies. At least two distinct GAS exposures were detected in each of the ARF sera tested. Furthermore, no two sera had the same T-antigen reactivity profile suggesting that each patient was exposed to a unique series of GAS T‑types prior to developing ARF. The methods have provided much-needed experimental evidence to substantiate the immune-priming hypothesis, and will facilitate further serological profiling studies that explore the multifaceted interactions between GAS and the host.

    This study sought to determine whether scabies infection is associated with acute rheumatic fever (ARF) or chronic rheumatic heart disease (CRHD). A cohort study was undertaken using health records of children aged 3-12 years attending an oral health service for the first time. Subjects were then linked to hospital diagnoses of scabies and ARF or CRHD. A total of 213 957 children free of rheumatic heart disease at baseline were available for analysis. During a mean follow-up time of 5.1 years, 440 children were diagnosed with ARF or CRHD in hospital records. Children diagnosed with scabies during follow-up were 23 times more likely to develop ARF or CRHD, compared with children who had no scabies diagnosis. After adjustment for confounders in a Cox model, the association reduced but remained strong (adjusted hazard ratio: 8.98; 95% confidence interval: 6.33-20.2). In an analysis restricted to children hospitalised at least once during follow-up, the adjusted hazard ratio for the same comparison was 3.43 (95% confidence interval: 1.85-6.37). A recent diagnosis of scabies from hospital records is strongly associated with a subsequent diagnosis of ARF. Further investigation of the role that scabies infestation may play in the aetiology of ARF is warranted. © 2018 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).

    The World Heart Federation criteria for the echocardiographic diagnosis of rheumatic heart disease (RHD) include a category "Borderline" RHD which may represent the earliest evidence of RHD. We aimed to determine the significance of minor heart valve abnormalities, including Borderline RHD, in predicting the future risk of acute rheumatic fever (ARF) or RHD. A prospective cohort study of Aboriginal and Torres Strait Islander children aged 8 to 18 years was conducted. Cases comprised children with Borderline RHD or other minor non-specific valvular abnormalities (NSVAs) detected on prior echocardiography. Controls were children with a prior normal echocardiogram. Participants underwent a follow-up echocardiogram 2.5 to 5 years later to assess for progression of valvular changes and development of Definite RHD. Interval diagnoses of ARF were ascertained. There were 442 participants. Cases with Borderline RHD were at significantly greater risk of ARF (incidence rate ratio 8.8, 95% CI 1.4-53.8) and any echocardiographic progression of valve lesions (relative risk 8.19, 95% CI 2.43-27.53) than their Matched Controls. Cases with Borderline RHD were at increased risk of progression to Definite RHD (1 in 6 progressed) as were Cases with NSVAs (1 in 10 progressed). Children with Borderline RHD had an increased risk of ARF, progression of valvular lesions, and development of Definite RHD. These findings provide support for considering secondary antibiotic prophylaxis or ongoing surveillance echocardiography in high-risk children with Borderline RHD.

    A total of 39 titles related to rheumatic fever or rheumatic heart disease in Malaysia were found with online literature search dating back to their inceptions and through 2014. Additional publications from conference journals were included. Nine papers were selected based on clinical relevance and future research implications. There were no population-based studies on the incidence or prevalence of ARF or RHD. In the 1980s, the incidence of admission due to ARF ranged from 2 to 21.1 per 100 000 paediatric admission per year. The burden of disease was significant in the adult population; 74.5% of patients with RHD were female, of which 77.1% were in the reproductive age group of 15-45 years old. Rheumatic mitral valve disease constituted almost half (46.7%) of all mitral valve repairs, ranging from 44.8 - 55.8 patients per year from 1997 - 2003. From 2010-2012, mitral valve interventions increased to 184 per year, of which 85.7% were mitral valve repair. In children with ARF, 25.4% - 41.7% had past history of rheumatic fever or RHD. In patients with rheumatic mitral valve disease undergoing surgical or medical interventions, only 6% reported history of ARF, none had history of GABHS pharyngitis or antibiotic prophylaxis. Only 44.7% of patients with RHD on follow-up were on intramuscular benzathine penicillin prophylaxis. Overall, there is scarcity of publications on ARF and RHD in Malaysia. Priority areas for research include determination of the incidence and prevalence of ARF and RHD, identification of high-risk populations, evaluation on the implementation and adherence of secondary preventive measures, identification of subclinical RHD especially amongst the high-risk population, and a surveillance system to monitor and evaluate preventive measures, disease progression and outcomes.

    Acute rheumatic fever (ARF) and its sequela chronic rheumatic heart disease remain significant causes of morbidity and mortality in New Zealand, particularly among Māori and Pacific peoples. Despite its importance, ARF epidemiology has not been reviewed recently. The aims of this study were to assess trends in ARF incidence rates between 1996 and 2005 and the extent to which ARF is concentrated in certain populations based on age, sex, ethnicity and geographical location. This descriptive epidemiological study examined ARF incidence rates using hospitalisation data (1996-2005) and population data from the 1996 and 2001 censuses. Rates were compared by using rate ratios and 95% confidence intervals. New Zealand's annual ARF rate was 3.4 per 100,000. ARF was concentrated in certain populations: 5- to 14-year-olds, Māori and Pacific peoples and upper North Island areas. From 1996 to 2005, the New Zealand European and Others ARF rate decreased significantly while Māori and Pacific peoples' rates increased. Compared with New Zealand European and Others, rate ratios were 10.0 for Māori and 20.7 for Pacific peoples. Of all cases, 59.5% were Māori or Pacific children aged 5-14 years, yet this group comprised only 4.7% of the New Zealand population. ARF rates in New Zealand have failed to decrease since the 1980s and remain some of the highest reported in a developed country. There are large, and now widening, ethnic disparities in ARF incidence. ARF is so concentrated by age group, ethnicity and geographical area that highly targeted interventions could be considered, based on these characteristics.

    Acute rheumatic fever (ARF) is an important public health problem in low- and middle-income countries and in certain populations in high-income countries. Indigenous Australians, and New Zealand Māori and Pacific people, have incidence rates among the highest in the world. We aimed to investigate ARF cases' housing conditions and sore throat treatment to identify opportunities for improving ARF prevention in New Zealand. Recently diagnosed cases and their care givers were interviewed. Information was obtained about the cases' demographics, housing circumstances and conditions, and sore throat treatment preceding ARF. We interviewed 55 cases. Most (75%) lived in rental housing and reported multiple measures of deprivation. Common exposures were household crowding (58%), bed-sharing (49%), dampness and mould (76%), cold (82%) and co-habiting with smokers (71%). Experiencing sore throat in the weeks before ARF was recalled by 62%, with 29% seeing a doctor or nurse and 13% of the total sample receiving antibiotics. The environmental conditions reported could contribute to high group A Streptococcus transmission and susceptibility to infection, thus increasing ARF risk. Sore throat treatment has important limitations as an intervention, particularly as 38% of participants did not recall sore throat preceding the diagnosis. The results support the need to improve rental housing. Interventions promoting minimum enforceable standards in social housing and private rental sectors (such as a housing warrant of fitness) could support these changes. A rigorous investigation, such as a case control study, is needed to explore risk factors further. © 2017 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).

    Chikungunya fever (CGF) and rickettsioses are known to cause acute onset febrile illnesses associated with severe arthritis. Rickettsial arthritis is curable with the use of appropriate anti-rickettsial antibiotics, however the arthritis of CGF tends to have a prolonged course leading to protracted disability. The aim of this study was to investigate the contribution of CGF and rickettsioses to cases of fever and arthritis during a presumed CGF outbreak in Sri Lanka. Fifty-eight consecutive patients with presumed CGF were further investigated to determine the occurrence of rickettsioses among them, and to identify differences in clinical, hematological, and biochemical parameters between the two diseases. Nearly a third of the patients had serological evidence of rickettsioses accounting for their illness. The presence of a late onset major joint arthropathy sparing the small joints of the hands and feet, and the occurrence of a late onset discrete maculopapular rash over the trunk and extremities, suggested rickettsioses over CGF. White blood cell count, erythrocyte sedimentation rate, C-reactive protein, and liver function tests were not helpful in differentiating rickettsioses from CGF. Patients with rickettsioses and arthritis who received an empirical course of doxycycline recovered faster than those who did not receive specific treatment. The establishment of rapid diagnostic methods able to differentiate the etiological agents of fever and arthritis, such as CGF and rickettsioses, would be beneficial in endemic settings.

    Implementation of nurse-initiated protocols to manage fever, hyperglycemia, and swallowing dysfunction decreased death and disability 90 days poststroke in the QASC trial (Quality in Acute Stroke Care) conducted in 19 Australian acute stroke units (2005-2010). We now examine long-term all-cause mortality. Mortality was ascertained using Australia's National Death Index. Cox proportional hazards regression compared time to death adjusting for correlation within stroke units using the cluster sandwich (Huber-White estimator) method. Primary analyses included treatment group only unadjusted for covariates. Secondary analysis adjusted for age, sex, marital status, education, and stroke severity using multiple imputation for missing covariates. One thousand and seventy-six participants (intervention n=600; control n=476) were followed for a median of 4.1 years (minimum 0.3 to maximum 70 months), of whom 264 (24.5%) had died. Baseline demographic and clinical characteristics were generally well balanced by group. The QASC intervention group had improved long-term survival (>20%), but this was only statistically significant in adjusted analyses (unadjusted hazard ratio [HR], 0.79; 95% confidence interval [CI], 0.58-1.07; P =0.13; adjusted HR, 0.77; 95% CI, 0.59-0.99; P =0.045). Older age (75-84 years; HR, 4.9; 95% CI, 2.8-8.7; P stroke severity (HR, 1.5; 95% CI, 1.3-1.9; P disease (including stroke) was listed either as the primary or secondary cause of death in 80% (211/264) of all deaths. Our results demonstrate the potential long-term and sustained benefit of nurse-initiated multidisciplinary protocols for management of fever, hyperglycemia, and swallowing dysfunction. These protocols should be a routine part of acute stroke care. URL: http://www.anzctr.org.au. Unique identifier: ACTRN12608000563369. © 2017 American Heart Association, Inc.

    Full Text Available Abstract Background Q fever is a zoonosis distributed worldwide that is caused by Coxiella burnetii infection and the defervescence usually occurs within few days of appropriate antibiotic therapy. Whether the changes of cytokine levels are associated with acute Q fever with persistent fever despite antibiotic therapy had not been investigated before. Case Presentation We report a rare case of acute Q fever granulomatous hepatitis remained pyrexia despite several antibiotic therapy and 6-day course of oral prednisolone. During the 18-month follow-up, the investigation of the serum cytokines profile and procalcitonin (PCT revealed that initially elevated levels of interleukin-2 (IL-2, IL-8, IL-10, and PCT decreased gradually, but the IL-6 remained in low titer. No evidence of chronic Q fever was identified by examinations of serum antibodies against C. burnetii and echocardiography. Conclusions The changes of cytokine levels may be associated with acute Q fever with poor response to treatment and PCT may be an indicator for monitoring the response to treatment.

    Arnebiaeuchroma (Royle) Johnst (Ruanzicao) is a traditional Chinese herbal medicine (TCM). It is extensively used in China and other countries for treatment of inflammatory diseases. It is known that hyper-activated complement system involves in the fever and acute lung injury (ALI) in rats. In our preliminary studies, anti-complementary activity of crude Arnebiaeuchroma polysaccharides (CAEP) had been demonstrated in vitro. This study aimed to investigate the role and mechanism of crude Arnebiaeuchroma polysaccharides (CAEP) using two animal models, which relate with inappropriate activation of complement system. In lipopolysaccharide (LPS)-induced fever model, the body temperature and leukocytes of peripheral blood in rats were significantly increased, while the complement levels of serum were remarkably decreased. CAEP administration alleviated the LPS-induced fever, reduced the number of leukocytes, and improved the levels of complement. Histological assay showed that there were severe damages and complement depositions in lung of the ALI rats. Further detection displayed that the oxidant stress was enhanced, and total hemolytic activity and C3/C4 levels in serum were decreased significantly in the ALI model group. Remarkably, CAEP not only attenuated the morphological injury, edema, and permeability in the lung but also significantly weakened the oxidant stress in bronchoalveolar lavage fluid (BALF) in the ALI rats. The levels of complement and complement depositions were improved by the CAEP treatment. In conclusion, the CAEP treatment ameliorated febrile response induced by LPS and acute lung injury induced by LPS plus ischemia-reperfusion. CAEP exerted beneficial effects on inflammatory disease potentially via inhibiting the inappropriate activation of complement system.

    Full Text Available Q fever is a bacterial infection affecting mainly the lungs, liver, and heart. It is found around the world and is caused by the bacteria Coxiella burnetii. The bacteria affects sheep, goats, cattle, dogs, cats, birds, rodents, and ticks. Infected animals shed this bacteria in birth products, feces, milk, and urine. Humans usually get Q fever by breathing in contaminated droplets released by infected animals and drinking raw milk. People at highest risk for this infection are farmers, laboratory workers, sheep and dairy workers, and veterinarians. Chronic Q fever develops in people who have been infected for more than 6 months. It usually takes about 20 days after exposure to the bacteria for symptoms to occur. Most cases are mild, yet some severe cases have been reported. Symptoms of acute Q fever may include: chest pain with breathing, cough, fever, headache, jaundice, muscle pains, and shortness of breath. Symptoms of chronic Q fever may include chills, fatigue, night sweats, prolonged fever, and shortness of breath. Q fever is diagnosed with a blood antibody test. The main treatment for the disease is with antibiotics. For acute Q fever, doxycycline is recommended. For chronic Q fever, a combination of doxycycline and hydroxychloroquine is often used long term. Complications are cirrhosis, hepatitis, encephalitis, endocarditis, pericarditis, myocarditis, interstitial pulmonary fibrosis, meningitis, and pneumonia. People at risk should always: carefully dispose of animal products that may be infected, disinfect any contaminated areas, and thoroughly wash their hands. Pasteurizing milk can also help prevent Q fever.

    Myanmar has a high burden of malaria with two-third of the population at risk of malaria. One of the basic elements of the Roll Back Malaria Initiative to fight against malaria is early diagnosis and treatment within 24 h of fever. Public awareness about malaria is a key factor in malaria prevention and control and in improving treatment-seeking behaviour. A large community-based survey was carried out in 27 townships of malaria endemic regions in Myanmar in 2015 which reported on the knowledge, behaviour and practices around malaria in the general population. We used the data already collected in this survey to assess (i) general public awareness of malaria and (ii) treatment-seeking behaviour and associated factors among persons with acute undifferentiated fever. A total of 6597 respondents from 6625 households were interviewed (response rate of 99.5%). About 85% of the respondents were aware that mosquito bite was the mode of transmission of malaria and 90% mentioned that malaria was preventable. However, only 16% of the respondents knew about anti-malaria drug resistance. There were certain misconceptions about the transmission of malaria such as dirty water, same blood group, sharing shelter, sleeping/eating together and poor hygiene. Health facility staff were the most common source of information about malaria (80%). Nearly one-fourth (23%) of the respondents with fever resorted to self-medication. Around 28% of the respondents with fever underwent blood testing, less than half of whom (44%) were tested within 24 h. Elderly age group, females, those with poor knowledge about malaria and those residing in non-Regional Artemisinin Resistance Initiative townships were associated with poor treatment-seeking behaviour in case of fever. Although there is fair knowledge on mosquito bite as a mode of transmission and prevention of malaria, there are some misconceptions about transmission of malaria. Those having poor knowledge about malaria have poor treatment

    In order to determine the role of levels of acute phase proteins (APPs) for the development of amyloidosis in familial Mediterranean fever (FMF) patients, the levels of serum amyloid A (SAA), C reactive protein (CRP), fibrinogen and erythrocyte sedimentation rate were measured in paired sera of 36 FMF patients during and in between acute attacks, 39 of their healthy parents (obligate heterozgotes), and 15 patients with FMF associated amyloidosis. To compare the levels of APPs, 39 patients with chronic infections or inflammatory diseases who may develop secondary amyloidosis, 20 patients with acute infections who are known to have elevated acute phase response but will never develop amyloidosis and 19 healthy controls were included. The median levels of all APPs are increased in the patients with FMF during attacks and a significant decrease was observed after the attack was over. The level of SAA was above reference range in all FMF patients during the attack free period and the level of at least one other APP was also above normal in 64% of the patients. Both CRP and SAA levels were found to be higher in obligate heterozygotes compared to controls. The levels of SAA in patients with FMF during the attack-free period, obligate heterozygotes and patients with FMF-amyloidosis were found to be similar. The levels in each group were found to be higher than SAA levels found in healthy controls yet lower than the levels measured in the patients with acute infections and patients with chronic inflammation or chronic infections. In conclusion, our results show that SAA level reflects subclinical inflammation with high sensitivity but its value for the prediction of amyloid formation process seems to be low.

    Twenty-nine classical swine fever virus (CSFv) strains were grown in the PK15 or SK6 cell lines. Antigenic differentiation studies were performed using monoclonal antibodies (McAbs), produced at Lelystad (CDI-DLO), The Netherlands. The monoclonals which were classified numerically as monoclonals 2-13. Epitope map patterns that resulted from the reactivity with McAbs were found to be unrelated to the pathogenicity of the viruses studied. Antigenic determinants were recognized by McAbs 5 and 8, were not detected in some Mexican strains; however, sites for McAb 6 were absent in all strains. The PAV-250 vaccine strain was recognized by all MAbs, except by MAb 6. Furthermore, the Chinese C-S vaccine strain was found to be very similar to the GPE(-) vaccine. None of the studied Mexican vaccines or field strains was found to be similar to the PAV-250 vaccine strain.

    2014-01-01

    Dengue fever, also known as breakbone fever, is a mosquito-borne infectious tropical disease caused by the dengue virus. Symptoms include fever, headache, muscle and joint pains, and a characteristic skin rash that is similar to measles. In a small proportion of cases, the disease develops into life-threatening dengue hemorrhagic fever, which results in bleeding, thrombocytopenia, and leakage of blood plasma, or into dengue shock syndrome, in which dangerously low blood pressure occurs. Treatment of acute dengue fever is supportive, with either oral or intravenous rehydration for mild or moderate disease and use of intravenous fluids and blood transfusion for more severe cases. Along with attempts to eliminate the mosquito vector, work is ongoing to develop a vaccine and medications targeted directly at the virus.

    2014-01-01

    Background Dengue fever is the most common identifiable cause of acute febrile illness among travelers returning from South America, South Central Asia, Southeast Asia, and the Caribbean. Although the characteristic exanthem of dengue fever occurs in up to 50% of patients, few descriptions of it are found in the dermatology literature, and discussions of how to distinguish the dengue exanthem from other infectious disease entities are rare. Chikungunya fever is an emerging infectious disease now seen in returning US tourists and should be considered in the differential diagnosis of dengue fever in the appropriate patient. Objective The purpose of our study was to report two cases of dengue fever among returning US tourists, provide a review of dengue fever, offer an extensive differential diagnosis of dengue fever, and raise awareness among dermatologists of chikungunya fever. Methods This study includes clinical findings of two returning travelers, one who traveled to Mexico and the other to Thailand, complemented by a discussion of both dengue fever and its differential diagnosis. Limitations Limited to 2 case reports. Conclusion Dengue fever should be considered in the differential diagnosis of fever and rash in the returning traveler. Dermatologists should be aware of the distinctive exanthem of dengue fever. Recognition of the dengue fever rash permits a rapid and early diagnosis, which is critical, as dengue fever can progress to life-threatening dengue hemorrhagic fever or dengue shock syndrome.

  14. Non-Steroid Anti-Inflammatory Drugs Are Better than Acetaminophen on Fever Control at Acute Stage of Fracture.

    Directory of Open Access Journals (Sweden)

    Kuang-Ting Yeh

    Full Text Available In addition to adequate surgical fixation and an aggressive rehabilitation program, pain relief is one of the most critical factors in the acute stage of fracture treatment. The most common analgesics are nonsteroid anti-inflammatory drugs and Acetaminophen, both of which relieve pain and reduce body temperature. In clinical experiences, they exhibit effective pain control; however, their influence on body temperature remains controversial. This study is aimed at determining the effects of analgesics at the acute stage of traumatic fracture by performing a clinical retrospective study of patients with fractures and a fracture animal model. The retrospective study revealed that, in the acetaminophen group, the mean value of postmedication body temperature (BT was significantly higher than that of the premedication BT. The change in BT was highly related with the medication rather than other risk factors. Forty eight 12-week-old male Wistar rats were divided into 6 groups: a control group, fracture group, fracture-Acetaminophen group, Acetaminophen group, fracture-Arcoxia group, and Arcoxia group. Fracture rats were prepared by breaking their unilateral tibia and fibula. Their inflammation conditions were evaluated by measuring their serum cytokine level and their physiological status was evaluated by estimating their central temperature, heart rate, and mean blood pressure. The hepatic adverse effects were assessed by measuring the serum levels of aspartate aminotransferase (sGOT and alanine aminotransferase (sGPT. The central temperature in the fracture-Acetaminophen group exceeded that in the groups fed normal saline water or Arcoxia. Accumulated hepatic injury was presented as steadily ascending curves of sGOT and sGPT. Inflammation-related cytokine levels were not higher in the Acetaminophen fracture group and were significantly lower in the fracture-Arcoxia group. Fever appeared to be aggravated by acetaminophen and more related to the

    2014-01-01

    Full Text Available Introduction. Neuroleptic malignant syndrome is rare, but potentially fatal idiosyncratic reaction to antipsychotic medications. It is sometimes difficult to diagnose some clinical cases as neuroleptic malignant syndrome and differentiate it from the acute viral encephalitis. Case report. We reported a patient diagnosed with acute psychotic reaction which appeared for the first time. The treatment started with typical antipsychotic, which led to febrility. The clinical presentation of the patient was characterised by the signs and symptoms that might have indicated the neuroleptic malignant syndrome as well as central nervous system viral disease. In order to make a detailed diagnosis additional procedures were performed: electroencephalogram, magnetic resonance imaging of the head, lumbar puncture and a serological test of the cerebrospinal fluid. Considering that after the tests viral encephalitis was ruled out and the diagnosis of neuroleptic malignant syndrome made, antipsychotic therapy was immediately stopped. The patient was initially treated with symptomatic therapy and after that with atypical antipsychotic and electroconvulsive therapy, which led to complete recovery. Conclusion. We present the difficulties of early diagnosis at the first episode of acute psychotic disorder associated with acute febrile condition. Concerning the differential diagnosis it is necessary to consider both neuroleptic malignant syndrome and viral encephalitis, i.e. it is necessary to make the neuroradiological diagnosis and conduct cerebrospinal fluid analysis and blood test. In neuroleptic malignant syndrome treatment a combined use of electroconvulsive therapy and low doses of atypical antipsychotic are confirmed to be successful.

    Fever is the most common symptom in children and can be classified as fever with or without focus. Fever without focus can be less than 7 d and is subclassified as fever without localizing signs and fever of unknown origin (FUO). FUO is defined as a temperature greater than 38.3 °C, for more than 3 wk or failure to reach a diagnosis after 1 wk of inpatient investigations. The most common causes of FUO in children are infections, connective tissue disorders and neoplasms. Infectious diseases most commonly implicated in children with FUO are salmonellosis, tuberculosis, malaria and rickettsial diseases. Juvenile rheumatic arthritis is the connective tissue disease frequently associated with FUO. Malignancy is the third largest group responsible for FUO in children. Diagnostic approach of FUO includes detailed history and examination supported with investigations. Age, history of contact, exposure to wild animals and medications should be noted. Examination should include, apart from general appearance, presence of sweating, rashes, tonsillitis, sinusitis and lymph node enlargement. Other signs such as abdominal tenderness and hepatosplenomegly should be looked for. The muscles and bones should be carefully examined for connective tissue disorders. Complete blood count, blood smear examination and level of acute phase reactants should be part of initial investigations. Radiological imaging is useful aid in diagnosing FUO. Trials of antimicrobial agents should not be given as they can obscure the diagnosis of the disease in FUO.

    Objective A fever is observed in approximately one-third of cases of acute aortic dissection (AAD); however, the causes remain unclear. We investigated the mechanism of a fever in AAD by measuring the serum concentrations of inflammatory markers, mediators of coagulation and fibrinolysis, and procalcitonin, a marker of bacterial infection. Methods We retrospectively studied 43 patients with medically treated AAD without apparent infection. Patients were divided into those with (Group A; n=19) and without (Group B; n=24) a maximum body temperature >38°C. We established which patients fulfilled the criteria for systemic inflammatory response syndrome (SIRS), and its relationship with a fever was examined. Mediators of inflammation, coagulation and fibrinolysis were compared by a univariate analysis. Factors independently associated with a fever were established by a multivariate analysis. Results The criteria for SIRS were fulfilled in a greater proportion of patients in Group A (79%) than in Group B (42%, p=0.001). There was no difference in the procalcitonin concentration between Groups A and B (0.15±0.17 ng/mL vs. 0.11±0.12 ng/mL, respectively; p=0.572). Serum procalcitonin concentrations lay within the normal range in all patients in whom it was measured, which showed that the fever was caused by endogenous mediators. On the multivariate analysis, there was a borderline significant relationship between a fever and the prothrombin time-International Normalized Ratio (p=0.065), likely reflecting the extrinsic pathway activity initiated by tissue factor. Conclusion Our findings suggest that a fever in AAD could be caused by SIRS, provoked by endogenous mediators that influence the extrinsic coagulation pathway without elevating the serum procalcitonin concentration.

    2005-08-01

    Full Text Available Abstract Mononuclear phagocytes are considered to be main targets for Dengue Virus (DENV replication. These cells are activated after infection, producing proinflammatory mediators, including tumour-necrosis factor-α, which has also been detected in vivo. Nitric oxide (NO, usually produced by activated mononuclear phagocytes, has antimicrobial and antiviral activities. Methods The expression of DENV antigens and inducible nitric oxide synthase (iNOS in human blood isolated monocytes were analysed by flow cytometry using cells either from patients with acute Dengue Fever or after DENV-1 in vitro infection. DENV-1 susceptibility to iNOS inhibition and NO production was investigated using NG-methyl L-Arginine (NGMLA as an iNOS inhibitor, which was added to DENV-1 infected human monocytes, and sodium nitroprussiate (SNP, a NO donor, added to infected C6/36 mosquito cell clone. Viral antigens after treatments were detected by flow cytometry analysis. Results INOS expression in activated monocytes was observed in 10 out of 21 patients with Dengue Fever and was absent in cells from ten healthy individuals. DENV antigens detected in 25 out of 35 patients, were observed early during in vitro infection (3 days, significantly diminished with time, indicating that virus replicated, however monocytes controlled the infection. On the other hand, the iNOS expression was detected at increasing frequency in in vitro infected monocytes from three to six days, exhibiting an inverse relationship to DENV antigen expression. We demonstrated that the detection of the DENV-1 antigen was enhanced during monocyte treatment with NGMLA. In the mosquito cell line C6/36, virus detection was significantly reduced in the presence of SNP, when compared to that of untreated cells. Conclusion This study is the first to reveal the activation of DENV infected monocytes based on induction of iNOS both in vivo and in vitro, as well as the susceptibility of DENV-1 to a NO production.

    Due to the risk of severe vaccine-associated adverse events, yellow fever vaccination in Brazil is only recommended in areas considered at risk for disease. From September 2008 through June 2009, two outbreaks of yellow fever in previously unvaccinated populations resulted in 21 confirmed cases with 9 deaths (case-fatality, 43%) in the southern state of Rio Grande do Sul and 28 cases with 11 deaths (39%) in Sao Paulo state. Epizootic deaths of non-human primates were reported before and during the outbreak. Over 5.5 million doses of yellow fever vaccine were administered in the two most affected states. Vaccine-associated adverse events were associated with six deaths due to acute viscerotropic disease (0.8 deaths per million doses administered) and 45 cases of acute neurotropic disease (5.6 per million doses administered). Yellow fever vaccine recommendations were revised to include areas in Brazil previously not considered at risk for yellow fever. PMID:24625634

    Full Text Available Abstract Background Liver injury due to dengue viral infection is not uncommon. Acute liver injury is a severe complicating factor in dengue, predisposing to life-threatening hemorrhage, Disseminated Intravascular Coagulation (DIC and encephalopathy. Therefore we sought to determine the frequency of hepatitis in dengue infection and to compare the outcome (length of stay, in hospital mortality, complications between patients of Dengue who have mild/moderate (ALT 23-300 IU/L v/s severe acute hepatitis (ALT > 300 IU/L. Methods A Cohort study of inpatients with dengue viral infection done at Aga Khan University Hospital Karachi. All patients (≥ 14 yrs age admitted with diagnosis of Dengue Fever (DF, Dengue Hemorrhagic Fever (DHF or Dengue Shock Syndrome (DSS were included. Chi square test was used to compare categorical variables and fischer exact test where applicable. Survival analysis (Cox regression and log rank for primary outcome was done. Student t test was used to compare continuous variables. A p value of less than or equal to 0.05 was taken as significant. Results Six hundred and ninety nine patients were enrolled, including 87% (605 patients with DF and 13% (94 patients with DHF or DSS. Liver functions tests showed median ALT of 88.50 IU/L; IQR 43.25-188 IU/L, median AST of 174 IU/L; IQR 87-371.5 IU/L and median T.Bil of 0.8 mg/dl; IQR 0.6-1.3 mg/dl. Seventy one percent (496 had mild to moderate hepatitis and 15% (103 had severe hepatitis. Mean length of stay (LOS in patients with mild/moderate hepatitis was 3.63 days v.s 4.3 days in those with severe hepatitis (P value 0.002. Overall mortality was 33.3% (n = 6 in mild/moderate hepatitis vs 66.7% (n = 12 in severe hepatitis group (p value Conclusion Severe hepatitis (SGPT>300IU in Dengue is associated with prolonged LOS, mortality, bleeding and RF.

    Full Text Available Dengue fever, also known as break bone fever, is a mosquito-borne infection that causes a severe flu-like illness. During the last few years, there had been increasing reports of dengue fever with unusual manifestations, primarily with neurological symptoms. Psychiatric morbidity during acute dengue infection has rarely been reported. There has not been any systemic study mentioning the prevalence and pattern of psychiatric sequelae. We report a 28-year-old male who after an acute dengue infection developed an episode of mania which was successfully treated.

    Full Text Available The erythrocyte sedimentation rate (ESR and C-reactive protein (CRP are employed in the evaluation of patients with suspected septic arthritis, osteomyelitis, and acute rheumatic fever. The purpose of this study is to determine if one test has greater sensitivity (rises earlier than the other. Laboratory data were retrieved for pediatric patients hospitalized with one of the above three conditions, who had both ESR and CRP tests done on or shortly prior to admission. Sensitivity calculations were performed for mild, moderate, and severe degrees of ESR and CRP elevation. Microcytic erythrocytes, as defined by mean corpuscular volume (MCV less than 80 μL, were identified to see if this affects the ESR. ESR or CRP sensitivities depend on the cutoff value (threshold chosen as a positive test. The sensitivities were similar for similar degrees of elevation. ESR and CRP discordance was not significantly related to MCV. We concluded that the CRP does not rise earlier than the ESR (their sensitivities are similar. Previously published conclusions are dependent on arbitrary thresholds. We could not find any evidence that MCV affects the ESR.

    2014-11-01

    Full Text Available Objective: In September 2012, there was an unexpected increase of acute febrile illness (AFI in Chuuk State of the Federated States of Micronesia. At the same time, dengue outbreaks were occurring in two of the Federated States of Micronesia’s other three states. The cause of AFI was suspected to be dengue; however, by the end of October, only one of 39 samples was positive for dengue. The objective of the investigation was to establish the cause of the outbreak. Methods: A line list was created and data analysed by time, place, person and clinical features. Reported symptoms were compared with the published symptoms of several diagnoses and laboratory testing undertaken. Results: Of the 168 suspected cases, 62% were less than 20 years of age and 60% were male. The clinical features of the cases were not typical for dengue but suggestive of respiratory illness. Nasopharyngeal swabs were subsequently collected and found to be positive for influenza. Public health measures were undertaken and the AFI returned to expected levels. Discussion: Clinical diagnosis of acute febrile illness (AFI can often be difficult and misleading. This can mean that opportunities for preventive measures early on in an outbreak are missed. In any outbreak, descriptive epidemiological analyses are valuable in helping to ascertain the cause of the outbreak.

  5. Microevolution of the chromosomal region of acute disease antigen A (adaA in the query (Q fever agent Coxiella burnetii.

    Directory of Open Access Journals (Sweden)

    Dimitrios Frangoulidis

    Full Text Available The acute disease antigen A (adaA gene is believed to be associated with Coxiella burnetii strains causing acute Q fever. The detailed analysis of the adaA genomic region of 23 human- and 86 animal-derived C. burnetii isolates presented in this study reveals a much more polymorphic appearance and distribution of the adaA gene, resulting in a classification of C. burnetii strains of better differentiation than previously anticipated. Three different genomic variants of the adaA gene were identified which could be detected in isolates from acute and chronic patients, rendering the association of adaA positive strains with acute Q fever disease disputable. In addition, all adaA positive strains in humans and animals showed the occurrence of the QpH1 plasmid. All adaA positive isolates of acute human patients except one showed a distinct SNP variation at position 431, also predominant in sheep strains, which correlates well with the observation that sheep are a major source of human infection. Furthermore, the phylogenetic analysis of the adaA gene revealed three deletion events and supported the hypothesis that strain Dugway 5J108-111 might be the ancestor of all known C. burnetii strains. Based on our findings, we could confirm the QpDV group and we were able to define a new genotypic cluster. The adaA gene polymorphisms shown here improve molecular typing of Q fever, and give new insights into microevolutionary adaption processes in C. burnetii.

    Differential diagnosis of acute abdomen in pregnant patients is one of the greatest challenges for the clinician. Occurrence of Familial Mediterranean Fever (FMF) paroxysm of peritonitis and acute cholecystitis during pregnancy is a unique clinical entity that leads to serious diagnostic and therapeutic dilemmas. We present the case of a 33-year-old Armenian patient at 16 weeks' gestational age with a history of FMF, who was admitted twice within 1 month with acute abdomen. The first episode was attributed to FMF and successfully treated conservatively with colchicine. The second episode was diagnosed as acute cholecystitis and led to emergent laparoscopic cholecystectomy and lysis of peritoneal adhesions from previous FMF attacks. The patient presented an uneventful postoperative clinical course and had a normal delivery of a healthy infant at the 39th week of gestation. Pregnant patients with acute abdomen should be evaluated with open mind. To the best of our knowledge, this is the first published report of the coexistence of 2 different causes of acute abdomen during pregnancy. Meticulous history and thorough physical, laboratory, and radiologic examination are the keys to reach a correct diagnosis. Treatment of pregnant patients with acute abdomen should be individualized. Administration of colchicine should be continued during conception, pregnancy, and lactation in patients with FMF history. Laparoscopic intervention in pregnant patients with surgical abdomen such as acute cholecystitis is the optimal method of treatment.

    The most dreaded complication of familial Mediterranean fever (FMF) is amyloidosis; controversy exists as to what acute phase reactant (APR) should be monitored in these patients. To analyze the best acute phase reactant for FMF follow-up to help guide physicians to decide on what APR parameter to use, we also attempted to define the best APR in predicting the complications of FMF, specifically the development of amyloidosis. Systematic review based on a sensitive search to capture studies that: (1) included FMF patients; (2) measured serum amyloid A (SAA), CRP (C-reactive protein), proteinuria, or ESR (erythrocyte sedimentation rate); (3) amyloidosis were the outcome measure; (4) sensitivity, specificity, predictive value, and other performance parameters could be calculated; and (5) had a longitudinal design. Of 1905 captured items, 26 were selected for detailed review, of which only two finally met the criteria, and the quality was only moderate; the articles did not analyzed the performance by means of sensitivity and specificity to predict, or even detect, amyloidosis, and thus had to be calculated based on text. The 26 screened studies were very heterogeneous in designs, parameters measured, and results, despite being set from research questions similar to ours. They were mainly descriptive, and it was very difficult to interpret the true performance of the tests. The correlation between the various APR is low. The evidence supporting the monitoring of FMF with any APR over the others is limited. Well designed longitudinal studies with a mixture of outcomes should be undertaken. Until them, recommending an APR over other would be based on expert opinion and indirect evidence.

    Fever is a common complaint in HIV-1 infected adults and may be a presenting sign of acute HIV-1 infection (AHI). We investigated the extent to which HIV-1 infection was considered in the diagnostic evaluation of febrile adults in sub-Saharan Africa (SSA) through a systematic review of published literature and guidelines in the period 2003-2014. We also performed a detailed audit of current practice for the evaluation of febrile young adults in coastal Kenya. Our review identified 43 studies investigating the aetiology of fever in adult outpatients in SSA. While the guidelines identified recommend testing for HIV-1 infection, none mentioned AHI. In our audit of current practice at nine health facilities, only 189 out of 1173 (16.1%) patients, aged 18-29 years, were tested for HIV-1. In a detailed record review, only 2 out of 39 (5.1%) young adults seeking care for fever were tested for HIV-1, and the possibility of AHI was not mentioned. Available literature on adult outpatients presenting with fever is heavily focused on diagnosing malaria and guidelines are poorly defined in terms of evaluating aetiologies other than malaria. Current practice in coastal Kenya shows poor uptake of provider-initiated HIV-1 testing and AHI is not currently considered in the differential diagnosis. © The Author 2014.

    Full Text Available Abstract Background Chikungunya virus (CHIKV is responsible for major epidemics worldwide. Autochthonous cases were recently reported in several European countries. Acute infection is thought to be monophasic. However reports on chronic pain related to CHIKV infection have been made. In particular, the fact that many of these patients do not respond well to usual analgesics suggests that the nature of chronic pain may be not only nociceptive but also neuropathic. Neuropathic pain syndromes require specific treatment and the identification of neuropathic characteristics (NC in a pain syndrome is a major step towards pain control. Methods We carried out a cross-sectional study at the end of the major two-wave outbreak lasting 17 months in Réunion Island. We assessed pain in 106 patients seeking general practitioners with confirmed infection with the CHIK virus, and evaluated its impact on quality of life (QoL. Results The mean intensity of pain on the visual-analogical scale (VAS was 5.8 ± 2.1, and its mean duration was 89 ± 2 days. Fifty-six patients fulfilled the definition of chronic pain. Pain had NC in 18.9% according to the DN4 questionnaire. Conversely, about two thirds (65% of patients with NC had chronic pain. The average pain intensity was similar between patients with or without NC (6.0 ± 1.7 vs 6.1 ± 2.0. However, the total score of the Short Form-McGill Pain Questionnaire (SF-MPQ(15.5 ± 5.2 vs 11.6 ± 5.2; p Conclusions There exists a specific chronic pain condition associated to CHIKV. Pain with NC seems to be associated with more aggressive clinical picture, more intense impact in QoL and more challenging pharmacological treatment.

    Doppler echocardiography has been demonstrated to be accurate in diagnosing valvular lesions in rheumatic heart disease (RHD) when compared to clinical evaluation alone. To perform Doppler echocardiography in children clinically diagnosed by the Jones criteria to have acute rheumatic fever (ARF), and to then compare the effectiveness of echo in detecting single/multi-valvular lesions with that of the initial clinical evaluation. We enrolled 93 children who were previously diagnosed with ARF by clinical examination. Presence of valvular lesions were enlisted, first by clinical auscultation, and then by performing Doppler echocardiography. We found that Doppler echocardiography was a sensitive technique, capable of detecting valvular lesions that were missed by clinical auscultation alone. Echocardiography of patients with carditis revealed mitral regurgitation to be the most common lesion present (53 patients, 56.98%), followed by aortic regurgitation in 21 patients (22.6%). The difference between clinical and echocardiographic diagnosis in ARF children with carditis was statistically significant for mitral regurgitation, aortic regurgitation and tricuspid regurgitation. Clinical auscultation alone revealed 4 cases of mitral stenosis, 39 mitral regurgitation, 14 aortic regurgitation, 9 tricuspid regurgitation; in contrast, echo revealed 5 cases of mitral stenosis, 53 mitral regurgitation, 21 aortic regurgitation, 18 tricuspid regurgitation. Doppler echocardiography is a more sensitive technique for detecting valvular lesions. In the setting of ARF, echo enables a 46.9% higher detection level of carditis, as compared to the clinical examination alone. Echo was very significant in detecting regurgitation lesions, especially for cases of tricuspid regurgitation in the setting of multivalvular involvement. The results of our study are in accordance with previous clinical studies, all of which clearly demonstrate the advantages of Doppler echocardiography, paving the way

    Streptococcus salivarius K12 (BLIS K12) is a probiotic strain strongly antagonistic to the growth of Streptococcus pyogenes, the most important bacterial cause of pharyngeal infections in humans. Shown to colonize the oral cavity and to be safe for human use, BLIS K12 has previously been reported to reduce pharyngo-tonsillitis episodes in children or adults known to have experienced recurrent streptococcal infection. The present study was focussed upon evaluating the role of BLIS K12 in the control of streptococcal disease and acute otitis media in children attending the first year of kindergarten. By randomization, 222 enrolled children attending the first year of kindergarten were divided into a treated group (N = 111) receiving for 6 months a daily treatment with BLIS K12 (Bactoblis®) and a control group (N = 111) who were monitored as untreated controls. During the 6 months of treatment and 3 months of follow-up, the children were evaluated for treatment tolerance, and for episodes of streptococcal pharyngo-tonsillitis, scarlet fever and acute otitis media. During the 6-month trial (N = 111 per group) the incidence of streptococcal pharyngo-tonsillitis, scarlet fever and acute otitis media was approximately 16%, 9% and 44% respectively in the treated group and 48%, 4% and 80% in the control group. During the 3-months follow-up (N = 29 per group) the corresponding rates of infection were 15%, 0% and 12% in the treated group and 26%, 6% and 36% in the controls. No apparent side effects were detected in the treated group either during treatment or follow-up. All of the enrolled children completed the study. The daily administration of BLIS K12 to children attending their first year of kindergarten was associated with a significant reduction in episodes of streptococcal pharyngitis and acute otitis media. No protection against scarlet fever was detected.

  15. Low frequency of acute hepatitis E virus (HEV) infections but high past HEV exposure in subjects from Cambodia with mild liver enzyme elevations, unexplained fever or immunodeficiency due to HIV-1 infection.

    In Cambodia, previous studies conducted on hepatitis E virus (HEV) infection are scant, sometimes old, and showed inconsistent results. Moreover, there is no data about HEV infection in Cambodian HIV-1-infected patients. To assess the occurrence of acute HEV infections and the level of past HEV exposure in one Mekong country. Using anti-HEV IgM and HEV RNA detection, we retrospectively investigated the presence of acute HEV infection in 825 individuals, including 350 subjects with or without fever, 300 subjects with or without liver enzyme elevations (LEE) and 175 antiretroviral treatment (ART)-naïve, severely immunocompromised HIV-1-infected patients. The detection of anti-HEV IgG was also performed to assess ancient HEV exposure. Nine individuals tested positive for anti-HEV IgM yielding an overall rate of 1.1% (95% confidence interval (CI), 0.5-2.0). We did not find significant differences for anti-HEV IgM rates between subjects with unexplained fevers (1.5%) and those with malaria or dengue-associated fever (1.7%) or non-febrile individuals (0%) (P=0.49), and between subjects with (1.5%) and without (2.0%) LEE (P=0.87). No HIV-infected patient tested positive for anti-HEV IgM. HEV RNA was not detected in all tested plasma specimens (n=578). Overall, the anti-HEV IgG prevalence rate was 30.1% (95% CI, 27.0-33.2). The scarcity of recent HEV infection contrasted with the high level of past HEV exposure. The role of HEV in liver disease is likely minor in Cambodia since no HEV RNA was detected in our studied populations, including HIV-positive patients with severe immunodepression.

    Each year, 1-4 % of people with known gallstones become symptomatic, either presenting with biliary colic or as acute cholecystitis. The distinction between both diagnoses remains challenging. To aid the proper diagnosis, the revised 2013 Tokyo Guidelines (TG 2013) were proposed with a self-acclaimed diagnostic accuracy of over 90 %. However, this accuracy has not been verified by others so far. To determine the accuracy of the TG 2013 guidelines in the diagnosis of acute cholecystitis both in its single components of fever, inflammatory markers and US features and of the combined application of the TG 2013 guidelines as a whole. A 5-year retrospective analysis equal to the TG 2013 validation process of all emergency cholecystectomies for acute cholecystitis or persistent biliary pain with an ultrasound performed during the same admission. Acute cholecystitis at histology was the golden standard. Inclusion criteria were met by 169 patients with a prevalence of acute cholecystitis of 52.7 %. The individual features of fever, gallbladder wall thickening and probe tenderness were not significant in univariate analysis. In multivariate analysis only, neutrophil count was an independent predictor. The combined application of the TG 2013 guidelines led to a better sensitivity of 83.1 % at the cost a reduced specificity of 37.5 % compared to neutrophil count alone. The accuracy was therefore only 60.3 %, which was well below the TG 2013 report. The 2013 Tokyo Guidelines were slightly better in predicting acute cholecystitis but over diagnosed two-thirds of normal gallbladders compared to neutrophil count alone.

    Full Text Available Pathogenesis of dengue involves suppression of immune system leading to development of characteristic presentation of haematological picture of thrombocytopenia and leucopenia. Sometimes, this suppression in immune response is responsible for deterioration in clinical status of the patient in spite of all specific and supportive therapy. Certain drugs like steroids are used for rescue therapy in conditions like sepsis. We present a novel use of filgrastim as a rescue therapy in a patient with dengue hemorrhagic fever (DHF with acute respiratory distress syndrome (ARDS, myocarditis, and febrile neutropenia and not responding to standard management.

    Rheumatic fever (RF) and its most severe sequela, chronic rheumatic heart disease (CRHD), are mediated by an abnormal immunological host response following a Streptococcus pyogenes oropharyngeal infection. Mannan-binding lectin (MBL), a collectin that activates complement, binds to N......-acetylglucosamine, a molecule present on the streptococcus cell wall and on human heart valves. As high levels of MBL and MBL2 associated genotypes have previously been seen to be associated with CRHD, we investigated the association between MBL2 polymorphisms and the presence of acute carditis and arthritis in patients...

    2014-05-01

    Full Text Available The spatial pattern and epidemiology of backyard pig farming and other low bio-security pig production systems and their role in the occurrence of classical swine fever (CSF is described and evaluated. A spatial Bayesian model was used to explore the risk factors, including human demographics, socioeconomic and environmental factors. The analyses were performed for Bulgaria, which has a large number of backyard farms (96% of all pig farms in the country are classified as backyard farms, and it is one of the countries for which both backyard pig and farm counts were available. Results reveal that the high-risk areas are typically concentrated in areas with small family farms, high numbers of outgoing pig shipments and low levels of personal consumption (i.e. economically deprived areas. Identification of risk factors and high-risk areas for CSF will allow to targeting risk-based surveillance strategies leading to prevention, control and, ultimately, elimination of the disease in Bulgaria and other countries with similar socio-epidemiological conditions.

    Yellow fever virus is a mosquito-borne flavivirus that causes yellow fever, an acute infectious disease that occurs in South America and sub-Saharan Africa. Most patients with yellow fever are asymptomatic, but among the 15% who develop severe illness, the case fatality rate is 20%-60%. Effective live-attenuated virus vaccines are available that protect against yellow fever (1). An outbreak of yellow fever began in Brazil in December 2016; since July 2017, cases in both humans and nonhuman primates have been reported from the states of São Paulo, Minas Gerais, and Rio de Janeiro, including cases occurring near large urban centers in these states (2). On January 16, 2018, the World Health Organization updated yellow fever vaccination recommendations for Brazil to include all persons traveling to or living in Espírito Santo, São Paulo, and Rio de Janeiro states, and certain cities in Bahia state, in addition to areas where vaccination had been recommended before the recent outbreak (3). Since January 2018, 10 travel-related cases of yellow fever, including four deaths, have been reported in international travelers returning from Brazil. None of the 10 travelers had received yellow fever vaccination.

    Carbohydrate overload models of equine acute laminitis are used to study the development of lameness. It is hypothesized that a diet-induced shift in cecal bacterial communities contributes to the development of the pro-inflammatory state that progresses to laminar failure. It is proposed that vasoactive amines, protease activators and endotoxin, all bacterial derived bioactive metabolites, play a role in disease development. Questions regarding the oral bioavailability of many of the bacterial derived bioactive metabolites remain. This study evaluates the possibility that a carbohydrate-induced overgrowth of potentially pathogenic cecal bacteria occurs and that bacterial translocation contributes toward the development of the pro-inflammatory state. Two groups of mixed-breed horses were used, those with laminitis induced by cornstarch (n=6) or oligofructan (n=6) and non-laminitic controls (n=8). Cecal fluid and tissue homogenates of extra-intestinal sites including the laminae were used to enumerate Gram-negative and -positive bacteria. Horses that developed Obel grade2 lameness, revealed a significant overgrowth of potentially pathogenic Gram-positive and Gram-negative intestinal bacteria within the cecal fluid. Although colonization of extra-intestinal sites with potentially pathogenic bacteria was not detected, results of this study indicate that cecal/colonic lymphadenopathy and eosinophilia develop in horses progressing to lameness. It is hypothesized that the pro-inflammatory state in carbohydrate overload models of equine acute laminitis is driven by an immune response to the rapid overgrowth of Gram-positive and Gram-negative cecal bacterial communities in the gut. Further equine research is indicated to study the immunological response, involving the lymphatic system that develops in the model. Copyright © 2012 Elsevier B.V. All rights reserved.

    Fever is a common presenting complaint among adult or pediatric patients in the emergency department setting. Although fever in healthy individuals does not necessarily indicate severe illness, fever in patients with neutropenia may herald a life-threatening infection. Therefore, prompt recognition of patients with neutropenic fever is imperative. Serious bacterial illness is a significant cause of morbidity and mortality for neutropenic patients. Neutropenic fever should trigger the initiation of a rapid work-up and the administration of empiric systemic antibiotic therapy to attenuate or avoid the progression along the spectrum of sepsis, severe sepsis, septic shock syndrome, and death.

    This study aims to (1) estimate the prevalence of acute respiratory infection (ARI) symptoms, diarrhoea and fever in the previous two weeks among 3-4 year old children who are/are not at-risk of intellectual disability in 24 low- and middle-income countries and (2) to investigate possible inequities in access to treatment among affected children. Cross-sectional survey. Secondary analysis of Rounds 4 and 5 UNICEF Multiple Indicator Cluster Surveys (MICS) from 24 low- and middle-income countries (n = 99,934 children). Pooled estimates indicated that young children at-risk of intellectual disability in low-income countries were significantly more likely than their peers to have reported symptoms of ARI and diarrhoea in the previous 2 weeks, and significantly less likely to have received appropriate treatment. Pooled estimates indicated that in middle-income countries children at-risk of intellectual disability were significantly more likely than their peers to have reported symptoms of ARI, diarrhoea and fever during the previous 2 weeks. Symptomatic children at-risk of intellectual disability were significantly less likely than their peers to have received antibiotics/antimotility medication for diarrhoea or antibiotics for ARI symptoms, but significantly more likely to be prescribed anti-malarials for fever. These results indicate the existence of significant inequalities and possible inequities in the exposure to and the treatment of three major infectious diseases among children who are/are not considered at-risk of intellectual disabilities in low- and middle-income countries.

    2017-04-01

    The definition of fever is flexible and depends on the clinical context. Fever is frequently observed in patients with cancer. Infectious and noninfectious causes of fever in patients with various oncological and hematological malignancies and the usefulness of biomarkers are discussed. To treat patients in a timely manner and to minimize morbidity and mortality, it is paramount that health care professionals determine the cause of fever. The usefulness of biomarkers in febrile patients with cancer continues to be controversial. Fever is frequently seen in patients with cancer and can be associated with a variety of infectious and noninfectious causes. The utility of acute-phase reactants, such as erythrocyte sedimentation rate, C-reactive protein, and procalcitonin, along with a nonsteroidal anti-inflammatory drug challenge should be further evaluated as adjunct tools for the workup of fever in patients with cancer.

    2010-01-01

    Full Text Available A middle-aged patient of Greenlandic origin was referred for skin infection of the leg. An initial minor trauma of the skin of the distal right lower extremity was complicated by bullous erysipelas which cultured positive for group A β-hemolytic streptococci (GABHS. The clinical condition deteriorated and necrotizing fasciitis developed despite relevant surgical and antibiotic treatment. Approximately 3 weeks later, the patient developed arthralgia, impaired renal function with azotemia, hypertension and severe nephrotic syndrome with periorbital and peripheral edema. A kidney biopsy demonstrated endocapillary glomerulonephritis. Concomitantly, carditis with chest pain, moderately reduced left ventricular ejection fraction and mitral regurgitation were noted. The patient had no signs of pharyngitis in the whole period. The patient thus contracted poststreptococ glomerulonephritis and furthermore she fulfilled the criteria of acute rheumatic fever following a GABHS skin infection. We suggest a possible relation between a virulent GABHS clone causing NF and ARF.

    Full Text Available Chikungunya fever, an emerging mosquito-borne viral disease, has affected Mauritius with two recent outbreaks in 2005 and 2006 respectively. A study was carried out in 2007 to describe the clinical complications post-Chikungunya infection. Ethical clearance was obtained for this study. Data collection was carried out in February and March 2007 on a sample of people who had suffered from Chikungunya fever by means of a comprehensive questionnaire. Participants comprised 77 people; there were 41 males and 36 females. Participants ranged from 6 to 69 years. 70 participants experienced persisting joint pains for at least 6 months following the acute phase. Of these, 35 had residual joint complaints after 6 months. 44 participants suffered from psychological sequelae. 10 participants had dermatological sequelae, 6 had iatrogenic complications due to non-steroidal anti-inflammatory drug (NSAID-induced gastritis, and 3 participants with serologically confirmed Chikungunya fever had neurological manifestations and changes on CT/MRI which could correspond to demyelination. Statistical analysis demonstrated that there was a weak linear relationship between the number of complications and increasing age; there was a significant difference in the number of complications according to gender, females being more affected than males; participants with co-morbidities had more complications and psychological sequelae than previously healthy participants. This study highlights that Chikungunya fever, which causes a significant impact on health in the acute phase, can have significant sequelae months afterwards and this includes psychological sequelae.

    Full Text Available Familial Mediterranean fever (FMF is a periodic autoinflammatory disease characterized by chronic inflammation. This study investigated the relationship between acute-phase reactants and gene mutations in attack-free periods of childhood FMF. Patients diagnosed with FMF were divided into four groups based on genetic features: no mutation, homozygous, heterozygous, and compound heterozygous. These groups were monitored for 2 years, and blood samples were collected every 6 months during attack-free periods. Erythrocyte sedimentation rate, C-reactive protein, fibrinogen, and white blood cell count were measured. A disease severity score was determined for each patient. Mean values for erythrocyte sedimentation rate and fibrinogen were significantly different in the homozygous group. White blood cell count and C-reactive protein were similar between the groups. Disease severity score was higher in patients with the M694V mutation than in individuals without the mutation, as well as in those with other mutation groups. Periodic follow-up of patients with FMF MEFV mutations in subjects with acute-phase reactants may be useful in the prevention of morbidity.

    Full Text Available The clinical characteristics of Q fever are poorly identified in the tropics. Fever with pneumonia or hepatitis are the dominant presentations of acute Q fever, which exhibits geographic variability. In southern Taiwan, which is located in a tropical region, the role of Q fever in community-acquired pneumonia (CAP has never been investigated.During the study period, May 2012 to April 2013, 166 cases of adult CAP and 15 cases of acute Q fever were prospectively investigated. Cultures of clinical specimens, urine antigen tests for Streptococcus pneumoniae and Legionella pneumophila, and paired serologic assessments for Mycoplasma pneumoniae, Chlamydophila pneumoniae, and Q fever (Coxiella burnetii were used for identifying pathogens associated with CAP. From April 2004 to April 2013 (the pre-study period, 122 cases of acute Q fever were also included retrospectively for analysis. The geographic distribution of Q fever and CAP cases was similar. Q fever cases were identified in warmer seasons and younger ages than CAP. Based on multivariate analysis, male gender, chills, thrombocytopenia, and elevated liver enzymes were independent characteristics associated with Q fever. In patients with Q fever, 95% and 13.5% of cases presented with hepatitis and pneumonia, respectively. Twelve (7.2% cases of CAP were seropositive for C. burnetii antibodies, but none of them had acute Q fever. Among CAP cases, 22.9% had a CURB-65 score ≧2, and 45.8% had identifiable pathogens. Haemophilus parainfluenzae (14.5%, S. pneumoniae (6.6%, Pseudomonas aeruginosa (4.8%, and Klebsiella pneumoniae (3.0% were the most common pathogens identified by cultures or urine antigen tests. Moreover, M. pneumoniae, C. pneumoniae, and co-infection with 2 pathogens accounted for 9.0%, 7.8%, and 1.8%, respectively.In southern Taiwan, Q fever is an endemic disease with hepatitis as the major presentation and is not a common etiology of CAP.

    Ischaemic stroke (IS), brain haemorrhage and cerebral venous thrombosis can occur as an early and late complication of cancer in the clinical course. Cancer patients are at increased risk for stroke from direct and indirect effects of their malignancy. The aim of our study was to evaluate the relationship between neoplastic disease and the long-term outcome, mortality and the presence of haemorrhagic complications in patients with acute IS treated with i.v. thrombolysis. We retrospectively evaluated the demographic and clinical data of 495 Caucasian patients with acute IS and 40 patients with IS and concomitant neoplastic disease who were consecutively treated from 2006 to 2013 in two experienced stroke centres. In analysed group, there were 7.8% of patients with cancer [50.0% male, mean age 72.3 ± 9.3; National Institutes of Health Stroke Scale - 13 (range 9.5-17)]. Cancer was diagnosed before i.v.-thrombolysis in 28 (70.0%) patients. After 3 months of follow up, 60% of patients were independent (mRS 0-2) compared with the group of patients without cancer - 55% (p = 0.54), 17.5% died (18.4%; p = 0.89), 12.4% suffered haemorrhagic transformation (HT) (17.6%; p = 0.41) and 2.5% experienced SICH (4.4%; p = 0.56, respectively). Other clinical complications were not found. A multivariate analysis showed no impact of neoplastic disease on unfavourable outcomes [modified Rankin scale 3-6)] after 3 months (p = 0.15). Intravenous thrombolysis performed in Caucasian stroke patients with past or current neoplastic diseases, but not in the course of chemo- and radiotherapy, can be a safe and effective method of treatment. In making decision on the thrombolytic treatment, the risk of bleeding complications and the life expectancy should be assessed. © 2015 John Wiley & Sons Ltd.

    Background Little is known about the development of chronic Q fever in occupational risk groups. The aim of this study was to perform long-term follow-up of Coxiella burnetii seropositive veterinarians and investigate the course of IgG phase I and phase II antibodies against C. burnetii antigens and to compare this course with that in patients previously diagnosed with acute Q fever. Methods Veterinarians with IgG phase I ≥1:256 (immunofluorescence assay) that participated in a previous seroprevalence study were asked to provide a second blood sample three years later. IgG antibody profiles were compared to a group of acute Q fever patients who had IgG phase I ≥1:256 twelve months after diagnosis. Results IgG phase I was detected in all veterinarians (n = 76) and in 85% of Q fever patients (n = 98) after three years (pveterinarians and 12% of patients (OR 3.95, 95% CI: 1.84–8.49). Conclusions IgG phase I persists among veterinarians presumably because of continuous exposure to C. burnetii during their work. Serological and clinical follow-up of occupationally exposed risk groups should be considered. PMID:25602602

    Coxiella burnetii causes Q fever, a zoonosis, which has acute and chronic manifestations. From 2007 to 2010, the Netherlands experienced a large Q fever outbreak, which has offered a unique opportunity to analyze chronic Q fever cases. In an observational cohort study, baseline characteristics and clinical characteristics, as well as mortality, of patients with proven, probable, or possible chronic Q fever in the Netherlands, were analyzed. In total, 284 chronic Q fever patients were identified, of which 151 (53.7%) had proven, 64 (22.5%) probable, and 69 (24.3%) possible chronic Q fever. Among proven and probable chronic Q fever patients, vascular infection focus (56.7%) was more prevalent than endocarditis (34.9%). An acute Q fever episode was recalled by 27.0% of the patients. The all-cause mortality rate was 19.1%, while the chronic Q fever-related mortality rate was 13.0%, with mortality rates of 9.3% among endocarditis patients and 18% among patients with a vascular focus of infection. Increasing age (P = 0.004 and 0.010), proven chronic Q fever (P = 0.020 and 0.002), vascular chronic Q fever (P = 0.024 and 0.005), acute presentation with chronic Q fever (P = 0.002 and P fever (P = 0.025 and P fever-related mortality, respectively.

    The purpose of this study is to determine erythrocyte sedimentation rate (ESR), C - reactive protein (CRP), serum amyloid-A (SAA) and cholesterol levels in patients with Crimean-Congo Hemorrhagic Fever (CCHF) and determine the relationship of these parameters with the severity of disease. By polymerase chain reaction and enzyme-linked immunosorbent assay (ELISA) method 40 patients were diagnosed as CCHF and 39 volunteer without any systemic disease whose blood were taken and their serum separated. SAA, CRP and ESR were measured with ELISA, nephelometry and Mix-Rate x100 vital diagnostic device, respectively, in serum samples. High density lipoprotein (HDL), low density lipoprotein (LDL) and total cholesterol levels were determined by using autoanalyzer HDL, LDL and total cholesterol kit (Syncron LX20). Statistically significant difference was determined between patients and controls in terms of the levels of SAA, CRP, HDL, LDL and total cholesterol (p0.05). Using of CRP and SAA together might increase the sensitivity of diagnosis of CCHF infection. However, none of the parameters investigated in this study were found to be a proper marker of the prognosis in CCHF. Cholesterol levels were significantly decreased in patients with CCHF, which was suggested to be associated with the increased serum levels of SAA in the patient group.

    Dengue fever is a tropical infection, which is mosquito-borne disease, caused by dengue virus and spread by Aedes mosquitoes. The incidence of dengue fever has risen rapidly over the past few years. About half of dengue infections are asymptomatic, and a great majority present with fever and body ache. However, the occurrence of complications is well known, including acute kidney injury (AKI). AKI in dengue is usually attributable to a pre-renal cause. Thrombotic microangiopathy is an extremely rare complication of dengue fever, with only a few published case reports in medical literature. This case intends to highlight the importance of recognizing dengue fever-induced thrombotic microangiopathy by physicians and pathologists, enabling better diagnosis and management of this life-threatening condition.

    We assessed patient outcomes 90 days after hospital admission for stroke following a multidisciplinary intervention targeting evidence-based management of fever, hyperglycaemia, and swallowing dysfunction in acute stroke units (ASUs). In the Quality in Acute Stroke Care (QASC) study, a single-blind cluster randomised controlled trial, we randomised ASUs (clusters) in New South Wales, Australia, with immediate access to CT and on-site high dependency units, to intervention or control group. Patients were eligible if they spoke English, were aged 18 years or older, had had an ischaemic stroke or intracerebral haemorrhage, and presented within 48 h of onset of symptoms. Intervention ASUs received treatment protocols to manage fever, hyperglycaemia, and swallowing dysfunction with multidisciplinary team building workshops to address implementation barriers. Control ASUs received only an abridged version of existing guidelines. We recruited pre-intervention and post-intervention patient cohorts to compare 90-day death or dependency (modified Rankin scale [mRS] ≥2), functional dependency (Barthel index), and SF-36 physical and mental component summary scores. Research assistants, the statistician, and patients were masked to trial groups. All analyses were done by intention to treat. This trial is registered at the Australia New Zealand Clinical Trial Registry (ANZCTR), number ACTRN12608000563369. 19 ASUs were randomly assigned to intervention (n=10) or control (n=9). Of 6564 assessed for eligibility, 1696 patients' data were obtained (687 pre-intervention; 1009 post-intervention). Results showed that, irrespective of stroke severity, intervention ASU patients were significantly less likely to be dead or dependent (mRS ≥2) at 90 days than control ASU patients (236 [42%] of 558 patients in the intervention group vs 259 [58%] of 449 in the control group, p=0·002; number needed to treat 6·4; adjusted absolute difference 15·7% [95% CI 5·8-25·4]).

    Dengue is an arboviral infection that classically presents with fever, joint pain, headaches, skin flush and morbilliform rashes. The incidence of neurological symptoms and complications in dengue varies from 1 to 25% that include encephalopathy, Guillain-Barre syndrome (GBS), acute motor weakness, seizures, neuritis, hypokalaemic paralysis, pyramidal tract signs, and a few more. Dengue fever as an antecedent infection in GBS is uncommon. A 34-years-old Sri Lankan Sinhalese male presented with fever, headache and myalgia of 3 days and developed leucopenia and thrombocytopenia without evidence of haemoconcentration. The diagnosis of dengue fever was confirmed as he had positive dengue NS1 antigen test on the third day of fever. He made full recovery and was discharged after 4 days of hospital stay. Six days later, he presented with history of acute flaccid weakness of both lower limbs and upper limbs which was of progressive ascending nature. The electromyography had evidence of demyelinating neuropathy and cerebrospinal fluid showed albuminocytological dissociation. Subsequently, IgM for dengue virus was positive. Dengue is endemic in Sri Lanka. Post dengue Guillain-Barre syndrome is a potential neurological complications of this infection.

    Radiation therapy to either mediastinum or pelvis causes a rapid decrease in circulating lymphocytes of both B and T types and in addition an impairment in the function of the remaining lymphocytes, as measured by their ability to proliferate in response to mitogens. The acute depression is short-lived. Substantial recovery is apparent within 3 wk after cessation of therapy; however, most patients show a modest, chronic depression in both numbers and functional capacities of circulating lymphocytes. T cells are somewhat more sensitive than B cells, but both are affected. Irradiation of the thymus per se seems to have little influence on the acute changes which occur, as patients receiving pelvic and mediastinal (including thymic) radiotherapy show a similar degree of lymphopenia and depression of lymphocyte responsiveness

    This study was undertaken to clarify the importance of nutritional status in patients with acute cholecystitis, and also evaluate whether they benefited from enteral nutrition supplementation, including medium-chain triglycerides (MCT), during the convalescent stage. Patients with acute cholecystitis admitted to our hospital between April 1994 and March 2002 were classified into a poor nutrition group (n=40; total serum proteinnutrition group (n=71; >5.0 g/dl). Patients with poor nutrition were significantly more elderly than those with fair nutrition, and had significantly higher serum C-reactive protein (CRP) concentrations. The two groups did not differ significantly with respect to other laboratory data, gender distribution, or medical treatment. We supplemented ordinary meals with enteral nutrition including MCT in 16 patients during the convalescent stage (MCT group). We compared their length of hospital stay and days required to recovery to pre-admission functional status for activities of daily living (ADL) with the same intervals in 16 patients without supplementation (non-MCT group) selected to match for age, gender, and fair or poor nutritional status from among 111 patients. Hospitalizations were significantly longer in the poor nutrition group (43.0+/-2.2 days) than in the fair nutrition group (27.0+/-8.2 days). Significantly more days were required to recover ADL status in the poor nutrition group (12.0+/-7.2 days) than in the fair group (9.4+/-5.2 days). Hospitalizations were significantly shorter in the MCT group (20.1+/-15 days) than in the non-MCT group (35.4+/-12.8 days). Significantly fewer days were required to recover ADL status in the MCT group (10.9+/-7 days) than in the non-MCT group (13.1+/-6.8 days). Administration of enteral nutrition including MCT during convalescence from acute cholecystitis thus appears to promote functional recovery shorten hospital stay.

    Children presenting with recurrent fever may represent a diagnostic challenge. After excluding the most common etiologies, which include the consecutive occurrence of independent uncomplicated infections, a wide range of possible causes are considered. This article summarizes infectious and noninfectious causes of recurrent fever in pediatric patients. We highlight that, when investigating recurrent fever, it is important to consider age at onset, family history, duration of febrile episodes, length of interval between episodes, associated symptoms and response to treatment. Additionally, information regarding travel history and exposure to animals is helpful, especially with regard to infections. With the exclusion of repeated independent uncomplicated infections, many infective causes of recurrent fever are relatively rare in Western countries; therefore, clinicians should be attuned to suggestive case history data. It is important to rule out the possibility of an infectious process or a malignancy, in particular, if steroid therapy is being considered. After excluding an infectious or neoplastic etiology, immune-mediated and autoinflammatory diseases should be taken into consideration. Together with case history data, a careful physical exam during and between febrile episodes may give useful clues and guide laboratory investigations. However, despite a thorough evaluation, a recurrent fever may remain unexplained. A watchful follow-up is thus mandatory because new signs and symptoms may appear over time.

    Dengue fever, also known as breakbone fever, is a mosquito-borne infectious tropical disease caused by the dengue virus. Symptoms include fever, headache, muscle and joint pains, and a characteristic skin rash that is similar to measles. In a small proportion of cases, the disease develops into life-threatening dengue hemorrhagic fever, which results in bleeding, thrombocytopenia, and leakage of blood plasma, or into dengue shock syndrome, in which dangerously low blood pressure occurs. Treat...

    In the majority of children with ALF, the etiology is unknown and liver transplantation is often needed for survival. A patient case prompted us to consider that immune dysregulation may be the cause of indeterminate acute hepatitis and liver failure in children. Our study includes nine pediatric patients treated under a multidisciplinary clinical protocol to identify and treat immune-mediated acute liver injury. Patients with evidence of inflammation and no active infection on biopsy received treatment with intravenous immune globulin and methylprednisolone. Seven patients had at least one positive immune marker before or after treatment. All patients had a CD8+ T-cell predominant liver injury that completely or partially responded to immune therapy. Five of the nine patients recovered liver function and did not require liver transplantation. Three of these patients subsequently developed bone marrow failure and were treated with either immunosuppression or stem cell transplant. This series highlights the importance of this tissue-based approach to diagnosis and treatment that may improve transplant-free survival. Further research is necessary to better characterize the immune injury and to predict the subset of patients at risk for bone marrow failure who may benefit from earlier and stronger immunosuppressive therapy. © 2014 John Wiley & Sons A/S.

    Infectious complications following delivery were, in the past, attributed to "milk fever": these were milk congestion, milk deposits, rancid milk, etc., that were held responsible. The milk was reabsorbed into the blood of the patient and settled in the peritoneum ("milk peritonitis"), in the broad ligaments (pelvic abscess), in the thighs (phlebitis) and also in the breasts (breast abscess). This belief, originated by Aristotle, was accepted by excellent authors like Andre Levret (1703-1780), one of the most famous French obstetricians and Nicolas Puzos, at the same time. More recently, authors alluded to it and blamed "milk fever" for being at the origin of dramatic pictures which they described in their novels, like Victor Hugo and Guy de Maupassant, for instance.

    Control of typhoid fever relies on clinical information, diagnosis, and an understanding for the epidemiology of the disease. Despite the breadth of work done so far, much is not known about the biology of this human-adapted bacterial pathogen and the complexity of the disease in endemic areas, especially those in Africa. The main barriers to control are vaccines that are not immunogenic in very young children and the development of multidrug resistance, which threatens efficacy of antimicrobial chemotherapy. Clinicians, microbiologists, and epidemiologists worldwide need to be familiar with shifting trends in enteric fever. This knowledge is crucial, both to control the disease and to manage cases. Additionally, salmonella serovars that cause human infection can change over time and location. In areas of Asia, multidrug-resistant Salmonella enterica serovar Typhi (S Typhi) has been the main cause of enteric fever, but now S Typhi is being displaced by infections with drug-resistant S enterica serovar Paratyphi A. New conjugate vaccines are imminent and new treatments have been promised, but the engagement of local medical and public health institutions in endemic areas is needed to allow surveillance and to implement control measures.

    Objective: Combining antidepressants (ADs) for therapy of acute depression is frequently employed, but randomized studies have yielded conflicting results. We conducted a systematic review and meta-analysis aimed at determining efficacy and tolerability of combination therapy. Methods: MEDLINE, Embase, PsycINFO, and CENTRAL databases were systematically searched through March 2014 for controlled studies comparing combinations of ADs with AD monotherapy in adult patients suffering from acute depression. The prespecified primary outcome was standardized mean difference (SMD), secondary outcomes were response, remission, and dropouts. Results: Among 8688 articles screened, 38 studies were eligible, including 4511 patients. Combination treatment was statistically, significantly superior to monotherapy (SMD 0.29; 95% CI 0.16 to 0.42). During monotherapy, slightly fewer patients dropped out due to adverse events (OR 0.90; 95% CI 0.53 to 1.53). Studies were heterogeneous (I2 = 63%), and there was indication of moderate publication bias (fail-safe N for an effect of 0.1:44), but results remained robust across prespecified secondary outcomes and subgroups, including analyses restricted to randomized controlled trials and low risk of bias studies. Meta-regression revealed an association of SMD with difference in imipramine-equivalent dose. Combining a reuptake inhibitor with an antagonist of presynaptic α2-autoreceptors was superior to other combinations. Conclusion: Combining ADs seems to be superior to monotherapy with only slightly more patients dropping out. Combining a reuptake inhibitor with an antagonist of presynaptic α2-autoreceptors seems to be significantly more effective than other combinations. Overall, our search revealed a dearth of well-designed studies. PMID:27582451

    Rift Valley fever is a potentially fatal disease of humans and domestic animals caused by Rift Valley fever virus (RVFV). Infection with RVFV in ruminants can cause near 100% abortion rates and recent outbreaks in naïve human populations have suggested case fatality rates of greater than thirty percent. To elucidate the roles that host proteins play during RVFV infection, proteomic analysis of RVFV virions was conducted using complementary analytical approaches, followed by functional validation studies of select identified host factors. Coupling the more traditional Gel LC/MS/MS approach (SDS PAGE followed by liquid chromatography tandem mass spectrometry) with an alternative technique that preserves protein complexes allowed the protein complement of these viral particles to be thoroughly examined. In addition to viral proteins present within the virions and virion-associated host proteins, multiple macromolecular complexes were identified. Bioinformatic analysis showed that host chaperones were among over-represented protein families associated with virions, and functional experiments using siRNA gene silencing and small molecule inhibitors identified several of these heat shock proteins, including heat shock protein 90 (HSP90), as important viral host factors. Further analysis indicated that HSP inhibition effects occur during the replication/transcription phase of the virus life cycle, leading to significant lowering of viral titers without compromising the functional capacity of released virions. Overall, these studies provide much needed further insight into interactions between RVFV and host cells, increasing our understanding of the infection process and suggesting novel strategies for anti-viral development. In particular, considering that several HSP90 inhibitors have been advancing through clinical trials for cancer treatment, these results also highlight the exciting potential of repurposing HSP90 inhibitors to treat RVF.

    Dengue fever is a common tropical infection. This acute febrile illness can be a deadly infection in cases of severe manifestation, causing dengue hemorrhagic shock. In this brief article, I will summarize and discuss the diagnosis and treatment of this disease. For diagnosis of dengue, most tropical doctors make use of presumptive diagnosis; however, the definite diagnosis should be based on immunodiagnosis or viral study. Focusing on treatment, symptomatic and supportive treatment is the main therapeutic approach. The role of antiviral drugs in the treatment of dengue fever has been limited, but is currently widely studied.

    Fever is common in patients with intracerebral hemorrhage (ICH). We sought to identify predictors of fever in patients hospitalized with ICH, and compare infectious fever with noninfectious fever. A retrospective review on consecutive spontaneous ICH patients from April 2009 to March 2010 was performed. Fever was defined as temperature 100.9°F or higher and attributed to infectious versus noninfectious etiology, based upon the National Healthcare Safety Network criteria. Univariate analysis and multivariable logistic regression model were used to determine factors associated with fever and with infection. Among the 351 ICH patients, 136 (39%) developed fever. Factors associated with fever included mean ICH volume, intraventricular hemorrhage (IVH), external ventricular drain (EVD) placement or surgical evacuation, positive microbial cultures, longer length of stay (LOS), and higher in-hospital mortality. Among patients with fever, 96 (71%) were noninfectious and 40 (29%) were infectious. Infectious fever was associated with higher LOS. Noninfectious fever was associated with higher in-hospital mortality. In multivariable analysis, ICH volume (OR = 1.01, P = .04), IVH (OR = 2.0, P = .03), EVD (OR = 3.7, P fever. Infectious fever (OR = 5.26, P = .004), EVD (OR = 4.86, P = .01), and surgical evacuation (OR = 4.77, P = .04) correlated with prolonged LOS when dichotomized using a median of 15 days. Fever is common in ICH patients and is not associated with a clear infectious etiology in the majority of patients. Patients with noninfectious fever have higher in-hospital mortality, but survivors have shorter LOS. Further studies are warranted to better understand fevers in ICH.

    Fever is one of the most common complaints in the emergency department (ED) and is more complex than generally appreciated. The broad differential diagnosis of fever includes numerous infectious and non-infectious etiologies. An essential skill in emergency medicine is recognizing the pitfalls in fever evaluation. This review provides an overview of the complaint of fever in the ED to assist the emergency physician with a structured approach to evaluation. Fever can be due to infectious or non-infectious etiology and results from the body's natural response to a pyrogen. Adjunctive testing including C-reactive protein, erythrocyte sedimentation rate, and procalcitonin has been evaluated in the literature, but these tests do not have the needed sensitivity and specificity to definitively rule in a bacterial cause of fever. Blood cultures should be obtained in septic shock or if the results will change clinical management. Fever may not be always present in true infection, especially in elderly and immunocompromised patients. Oral temperatures suffer from poor sensitivity to diagnose fever, and core temperatures should be utilized if concern for fever is present. Consideration of non-infectious causes of elevated temperature is needed based on the clinical situation. Any fever evaluation must rigorously maintain a broad differential to avoid pitfalls that can have patient care consequences. Fever is complex and due to a variety of etiologies. An understanding of the pathophysiology, causes, and assessment is important for emergency physicians. Published by Elsevier Inc.

    A 51-year-old woman diagnosed as having left breast cancer with axillary lymph node and liver metastases seven years earlier was seen in our office because of severe pancytopenia. She had received chemotherapy including several cycles of doxorubicin plus cyclophosphamide and docetaxel followed by hormone therapy containing leuprorelin and tamoxifen over four years. For management of bone pain due to metastasis, she had also undergone stereotaxic radiation therapy of the neck one and a half years earlier and unsealed internal radiation therapy with (89)Sr injection five months prior to the current presentation, Subsequently, myelosuppression progressively worsened and she finally required a blood transfusion. Although bone marrow examination showed severe hypoplasia, but neither blastic nor dysplastic, a test for PML-RARA fluorescence in situ hybridization was positive. After administration of all-trans retinoic acid, hematogenesis improved within three weeks. Neither disseminated intravascular coagulation nor retinoic acid syndrome was observed during the course of her illness. This is the first report describing acute promyelocytic leukemia after administration of (89)Sr, to our knowledge, and with an atypical onset and progression. As the number of cancer survivors increases due to improvements in medical intervention, clinicians must take more notice of special characteristics of therapy-related leukemia modified by previous treatments.

    Dengue fever is a frequent cause of morbidity in travellers. The objective was to describe the epidemiological and clinical characteristics of dengue fever in Czech travellers. This descriptive study includes patients with acute dengue fever diagnosed at Hospital Na Bulovce during 2004-2013. Data were collected and analysed retrospectively. A total of 132 patients (83 males and 49 females) of median age 33 years (IQR 29-40) were included. Diagnosis was established by NS1 antigen detection in 87/107 cases (81.3%) and/or RT-PCR in 50/72 (69.4%) and by serology in 25 cases (18.9%). Dengue was acquired in South-East Asia in 69 cases (52.3%), followed by South Asia (48 cases; 36.3%), Latin America (14; 10.6%) and Sub-Saharan Africa (1; 0.8%). The most frequent symptoms included fever, rash and headache. Initial leukocyte and lymphocyte counts were lower in patients who presented in the early phase (0-4 days), however, platelet count was lower and AST, ALT and LDH activity higher in patients with a longer symptoms duration (≥5 days). The clinical course was mostly uncomplicated. Dengue fever is becoming a frequent cause of fever in Czech travellers. Clinicians should be familiar with the typical clinical findings and novel diagnostic methods. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Dengue fever, also known as breakbone fever, is an infectious tropical disease caused by the Dengue virus. It is associated with a number of complications, which are well documented. However, Dengue fever associated with rectus sheath hematoma (RSH) is a very rare complication. Only one case report has been published prior supporting the association of Dengue fever with RSH. We report a case of Dengue fever who presented with RSH and was successfully treated conservatively. RSH is also an uncommon cause of acute abdominal pain. It is accumulation of blood in the sheath of the rectus abdominis, secondary to rupture of an epigastric vessel or muscle tear.

    Full Text Available Abstract Background 5,10-methylenetetrahydrofolate reductase (MTHFR variants, C677T and A1298C, have been reported to be associated with decreased risk of acute lymphoblastic leukemia (ALL. However, results derived from individually underpowered studies are conflicting. We carried out an updated meta-analysis on the association between MTHFR polymorphisms and ALL risk. Methods Relevant publications were searched through PUBMED and EMBASE databases. The associations between MTHFR C677T and A1298C polymorphisms and the risk of ALL were evaluated by odds ratios (ORs. The heterogeneity and publication bias were estimated. Meta-regression analysis was performed to evaluate the potential sources of heterogeneity. Results C677T polymorphism was associated with a reduced risk of ALL (allele contrast: ORRE = 0.91, 95% CI: 0.83-0.99. Subgroup analysis showed MTHFR C677T variant was associated with decreased susceptibility to ALL in children and Caucasians. Meta-regression showed the logOR for the association between T allele and ALL increased as sex ratio (M/F in the case group increased (P = 0.01. Regarding A1298C polymorphism, no significant association was observed (allele contrast: ORRE = 1.01, 95% CI: 0.91-1.11. There was no publication bias for C677T or A1298C polymorphism. Conclusions The present meta-analysis suggests that the C677T polymorphism, not A1298C, in MTHFR gene is associated with a decreased risk of ALL, particularly among children and Caucasians subjects. Our findings suggest that the influence of the C677T polymorphism on ALL susceptibility is modified by sex ratio in cases (M/F. Since folate intake may be a possible confounding factor, including this factor in future prospective studies is warranted. Further meta-analysis studies should be at least stratified for folate levels and gender to give more powerful and informative results.

    2013-01-01

    Full Text Available Viral hemorrhagic fevers (VHFs caused by arenaviruses are acute diseases characterized by fever, headache, general malaise, impaired cellular immunity, eventual neurologic involvement, and hemostatic alterations that may ultimately lead to shock and death. The causes of the bleeding are still poorly understood. However, it is generally accepted that these causes are associated to some degree with impaired hemostasis, endothelial cell dysfunction and low platelet counts or function. In this article, we present the current knowledge about the hematological alterations present in VHF induced by arenaviruses, including new aspects on the underlying pathogenic mechanisms.

    Between 2000 and 2015, 904 cases of acute Q fever were reported in England and Wales. The case dataset had a male to female ratio of 2.5:1, and a median age of 45 years. Two outbreaks were recognised during this time period, and the incidence of sporadic cases was highest across the southwest of England, and Wales. There are limitations in the surveillance system for Q fever, including possible geographical differences in reporting and limited epidemiological data collection. The surveillance system needs to be strengthened in order to improve the quality and completeness of the epidemiological dataset. The authors conclude with recommendations on how to achieve this.

We performed a prospective age-stratified study in outpatient clinics investigating the prevalence of DF; 578 patients were enrolled, and 317 patients with a negative rapid diagnostic test (RDT) for malaria were tested for dengue. Malaria was confirmed in 52% (301/578, 95% confidence interval [CI] = 48-56%), DF was diagnosed in 8% (46/578, 95% CI = 6-10%), and 40% (95% CI = 36-44%) had neither diagnosis. Among the 317 malaria RDT-negative patients, 14% (45/317, 95% CI = 10-18%) had DF. The seroprevalence of dengue immunoglobulin G (IgG) was 83% (204/247, 95% CI = 78-87%), and no dengue hemorrhagic fever was seen. This study provides good evidence for the first time that DF is common in PNG and is responsible for 8% of fever episodes. The common occurrence of DF in a population with presumed previous exposure to dengue is an important observation.

    Fever frequently occurs in stroke patients and worsens their prognosis. However, only few studies have assessed the determinants of fever in acute stroke, and no study has specifically addressed the possible prediction of the development of fever. This investigation included 536 patients with acute stroke and a body temperature =37.5°C starting after 24 h). Among the clinical variables available during the first 24 h from admission, those predictive of the subsequent appearance of fever were searched for. One hundred further patients had a temperature >37°C during the first 24 h. In univariate analysis, many variables were predictive of the subsequent development of fever, but in multivariate analysis, only the following four predictors remained significant (odds ratio [95% confidence interval], P value): nasogastric tube (4.0 [2.2-7.4], 37°C during the first 24 h were as follows: National Institutes of Health Stroke Scale (P nasogastric tube was the strongest and most significant one. © 2015 John Wiley & Sons A/S.

    To determine the frequency of dengue as a cause of fever and compare the clinical and haematological characteristics of Dengue-probable and Dengue-proven cases. All patients with age above 14 years, who were either hospitalized or treated in medical outdoor clinic due to acute febrile illness, were evaluated for clinical features of Dengue Fever (DF), Dengue haemorrhagic fever (DHF) and Dengue Shock Syndrome (DSS). Patients showing typical clinical features and haematological findings suggestive of Dengue fever (As per WHO criteria) were evaluated in detail for comparison of probable and confirmed cases of Dengue fever. All other cases of acute febrile illness, not showing clinical features or haematological abnormalities of Dengue fever, were excluded. The clinical and laboratory features were recorded on SPSS 11.0 programme and graded where required, for descriptive and statistical analysis. Out of 5200 patients with febrile illness, 107 (2%) presented with typical features of DF, 40/107 (37%) were Dengue-proven while 67/107 (63%) were Dengue-probable. Out of Dengue-proven cases, 38 were of DF and 2 were of DHF. Day 1 temperature ranged from 99-105 degreeC (mean 101 degree C). Chills and rigors were noticed in 86 (80%), myalgia in 67%, headache in 54%, pharyngitis in 35%, rash in 28%, and bleeding manifestations in 2% cases. Hepatomegaly in 1(0.5%), lymphadenopathy in 1 (0.5%) and splenomegaly in 12 (11.2%) cases. Leucopoenia (count 40 U/L in 57% cases. Frequency of clinically suspected dengue virus infection was 107 (2%), while confirmed dengue fever cases were 40 (0.8%) out of 5200 fever cases. Fever with chills and rigors, body aches, headache, myalgia, rash, haemorrhagic manifestations, platelet count, total leukocyte count, and ALT, are parameters to screen the cases of suspected dengue virus infection, the diagnosis cannot be confirmed unless supported by molecular studies or dengue specific IgM.

    The aim of the article is to discuss issues associated with the occurrence of febrile illnesses in leisure and business travellers, with a particular emphasis on fevers of unknown origin (FUO). FUO, apart from diarrhoeas, respiratory tract infections and skin lesions, are one of the most common health problems in travellers to tropical and subtropical countries. FUO are manifestations of various diseases, typically of infectious or invasive aetiology. In one out of 3 cases, the cause of a fever in travellers returning from the hot climate zone is malaria, and therefore diagnostic tests should first aim at ruling out this specific disease entity. Other illnesses with persistent fever include dengue, enteric fever, viral hepatitis A, bacterial diarrhoeas and rickettsioses. Fever may also occur in travellers suffering from diseases of non-tropical origin, e.g. cosmopolitan respiratory tract or urinary tract infections, also, fever may coexist with other illnesses or injuries (skin rashes, bites, burns).

    Objective: This study was designed to determine the frequency, pattern and management of surgical complications among patients with dengue fever. Design: Cross sectional study design was used. Settings: Hameed Latif Hospital, Lahore. Methods: From March - 2009 to December - 2011 total of 875 patients of dengue fever with positive anti-dengue immunoglobulin M (IgM) serology were included in this study. Complete blood count, liver function test, blood urea, serum creatinin, serum amylase were determined in all patients admitted with the diagnosis of dengue fever. All the patients were evaluated for the presence of surgical complications by physical examination and real time ultrasound abdomen. Patient had CT - abdomen and brain where it was required. Patients having surgical complications were managed in dengue ward and ICU with multidisciplinary approach. Data entry and analysis was done by using SPSS 16. Results: Among 875 patients with dengue fever, 491 (43.9%) patients were men and 384 (48.9%) were women with age range (18 - 70) years. Surgical complications were detected in 121 (13.8%) patients: acute cholecystitis in 46 (5.26%); acute pancreatitis in 19 (2.17%); injection abscess in 14 (1.6%); gastrointestinal bleed in 24 (2.74%); forearm compartment syndrome in 3 (0.34%); abdominal compartment syndrome in 2 (0.23%) and acute appendicitis, 4 (0.46%) patients. Cerebral bleed, retroperitoneal hematoma, abdominal wall hematoma and splenic rupture was seen among 3 (0.34%), 2 (0.23%), 3 (0.34%), and 1 (0.11%) patients, respectively. Out of 121 patients surgery was done in 20 (16.5%) patients while rest of 101 (83.5%) patients were managed conservatively. Two patients died. Conclusion: Surgical complications are common and should be suspected in every patient with dengue fever. Majority of surgical manifestations of dengue fever were managed conservatively however surgical intervention was done in certain cases with favorable outcome. (author)

    Introduction Viral etiologies of fever, including dengue, Chikungunya, influenza, rota and adeno viruses, cause major disease burden in tropical and subtropical countries. The lack of diagnostic facilities in developing countries leads to failure to estimate the true burden of such illnesses, and generally the diseases are underreported. These diseases may have similar symptoms with other causes of acute febrile illnesses including malaria and hence clinical diagnosis without laboratory tests...

    Viral hemorrhagic fevers (VHFs) typically manifest as rapidly progressing acute febrile syndromes with profound hemorrhagic manifestations and very high fatality rates. Lassa fever, an acute hemorrhagic fever characterized by fever, muscle aches, sore throat, nausea, vomiting, diarrhea and chest and abdominal pain. Rodents are important reservoirs of rodent-borne zoonosis worldwide. Transmission rodents to humans occur by aerosol spread, either from the genus Mastomys rodents' excreta (multimammate rat) or through the close contact with infected patients (nosocomial infection). Other rodents of the genera Rattus, Mus, Lemniscomys, and Praomys are incriminated rodents hosts. Now one may ask do the rodents' ectoparasites play a role in Lassa virus zoonotic transmission. This paper summarized the update knowledge on LHV; hopping it might be useful to the clinicians, nursing staff, laboratories' personals as well as those concerned zoonoses from rodents and rodent control.

    2016-12-15

    Chikungunya fever, an acute and often chronic arthralgic disease caused by the mosquito-borne chikungunya virus (CHIKV), has reemerged since 2004 to cause millions of cases. Because CHIKV exhibits limited antigenic diversity and is not known to be capable of reinfection, a vaccine could serve to both prevent disease and diminish human amplification during epidemic circulation. Here, we review the many promising vaccine platforms and candidates developed for CHIKV since the 1970s, including several in late preclinical or clinical development. We discuss the advantages and limitations of each, as well as the commercial and regulatory challenges to bringing a vaccine to market. © The Author 2016.

    Full Text Available The paper presents the clinical results of a double-blind, randomized, placebo-controlled multicenter phase III study evaluating the clinical efficacy and safety of Ingavirin® capsules 30 mg at a daily dose of 60 mg for the treatment of influenza and other acute respiratory viral infections (ARVI in 7–12-year-old children.The study included 310 children of both sexes. The study participants took Ingavirin® 60 mg/day or placebo for 5 days. The drug was shown to be effective in normalizing temperature and alleviating intoxication and catarrhal syndromes just at day 3 of therapy. Ingavirin® was demonstrated to considerably reduce the risk of bacterial complications of ARVI/influenza, which require antibiotic therapy, which is important for clinical use in children. This clinical trial has shown the high safety and tolerance of the drug. Ingavirin® contributes to accelerated virus elimination, shorter disease duration, and lower risk of complications.

    Full Text Available BACKGROUND: The bacterium Salmonella enterica serovar Typhi causes typhoid fever, which is typically associated with fever and abdominal pain. An outbreak of typhoid fever in Malawi-Mozambique in 2009 was notable for a high proportion of neurologic illness. OBJECTIVE: Describe neurologic features complicating typhoid fever during an outbreak in Malawi-Mozambique METHODS: Persons meeting a clinical case definition were identified through surveillance, with laboratory confirmation of typhoid by antibody testing or blood/stool culture. We gathered demographic and clinical information, examined patients, and evaluated a subset of patients 11 months after onset. A sample of persons with and without neurologic signs was tested for vitamin B6 and B12 levels and urinary thiocyanate. RESULTS: Between March - November 2009, 303 cases of typhoid fever were identified. Forty (13% persons had objective neurologic findings, including 14 confirmed by culture/serology; 27 (68% were hospitalized, and 5 (13% died. Seventeen (43% had a constellation of upper motor neuron findings, including hyperreflexia, spasticity, or sustained ankle clonus. Other neurologic features included ataxia (22, 55%, parkinsonism (8, 20%, and tremors (4, 10%. Brain MRI of 3 (ages 5, 7, and 18 years demonstrated cerebral atrophy but no other abnormalities. Of 13 patients re-evaluated 11 months later, 11 recovered completely, and 2 had persistent hyperreflexia and ataxia. Vitamin B6 levels were markedly low in typhoid fever patients both with and without neurologic signs. CONCLUSIONS: Neurologic signs may complicate typhoid fever, and the diagnosis should be considered in persons with acute febrile neurologic illness in endemic areas.

    2012-05-17

    We conducted a phase 2 study of ruxolitinib in patients with relapsed/refractory leukemias. Patients with acceptable performance status (0-2), adequate organ function, and no active infection, received ruxolitinib 25 mg orally twice a day for 4 weeks (1 cycle). Response was assessed after every 2 cycles of treatment, and patients who completed 2 cycles were allowed to continue treatment until disease progression. Dose escalation to 50 mg twice daily was permitted in patients demonstrating a benefit. Thirty-eight patients, with a median age of 69 years (range, 45-88), were treated. The median number of prior therapies was 2 (range, 1-6). Twelve patients had JAK2V617F mutation. Patients received a median of 2 cycles of therapy (range, 1-22). Three of 18 patients with postmyeloproliferative neoplasm (MPN) acute myeloid leukemia (AML) showed a significant response; 2 achieved complete remission (CR) and one achieved a CR with insufficient recovery of blood counts (CRi). The responding patients with palpable spleens also had significant reductions in spleen size. Overall, ruxolitinib was very well tolerated with only 4 patients having grade 3 or higher toxicity. Ruxolitinib has modest antileukemic activity as a single agent, particularly in patients with post-MPN AML. The study was registered at www.clinicaltrials.gov as NCT00674479.

    2017-08-31

    Familial Mediterranean fever is an autosomal recessive disease characterized by recurrent episodes of fever and polyserositis and by the onset of reactive amyloid-associated amyloidosis. Amyloidosis due to familial Mediterranean fever can lead to end-stage renal disease, culminating in kidney transplantation for some patients. In this study, we report the clinical outcome of two brothers with familial Mediterranean fever who were the inadvertent donor and recipient, respectively, of a kidney. Subsequently, they were diagnosed with renal amyloidosis secondary to familial Mediterranean fever and were successfully treated with anakinra and colchicine. Two brothers with familial Mediterranean fever and renal amyloidosis were the inadvertent donor and recipient, respectively, of a kidney. The recipient had presented recurrent acute febrile episodes of familial Mediterranean fever, developed nephrotic syndrome secondary to amyloidosis and needed bilateral nephrectomy and chronic dialysis. His elder brother, in apparent good health, donated his left kidney to his brother. Immediately after the kidney transplantation, both the donor and recipient presented massive proteinuria, impaired renal function and elevated serum amyloid A levels. Biopsies of the brothers' kidneys showed amyloidosis. Genetic studies thereafter revealed a homozygous variant for the MEFV gene (NM_000243.2.c.2082G > A; p.M694I) in both brothers. At this point, both the donor and recipient were treated with colchicine and anakinra, resulting in improved renal function, decreased proteinuria, undetectable serum amyloid A levels and stable renal function at 62 months of follow-up and no major adverse effects. In familial Mediterranean fever, analyses of the MEFV gene should be performed in potential live kidney donors from a direct family member (either between siblings or between parents and children). In addition, genetic studies are required when consanguinity is suspected between members involved in

    2004-12-01

    Crimean-Congo hemorrhagic fever (CCHF) is an acute infectious disease caused by CCHF virus (CCHFV), a member of the family Bunyaviridae, genus Nairovirus. The case fatality rate of CCHF ranges from 10-40%. Because CCHF is not present in Japan, many Japanese virologists and clinicians are not very familiar with this disease. However, there remains the possibility of an introduction of CCHFV or other hemorrhagic fever viruses into Japan from surrounding endemic areas. Development of diagnostic laboratory capacity for viral hemorrhagic fevers is necessary even in countries without these diseases. At the National Institute of Infectious Diseases, Tokyo, Japan, laboratory-based systems such as recombinant protein-based antibody detection, antigen-capture and pathological examination have been developed. In this review article, epidemiologic and clinical data on CCHF in the Xinjiang Uygur Autonomous Region, compiled through field investigations and diagnostic testing utilizing the aforementioned laboratory systems, are presented. CCHFV infections are closely associated with the environmental conditions, life styles, religion, occupation, and human economic activities. Based on these data, preventive measures for CCHFV infections are also discussed.

    2018-03-01

    Typhoid fever (enteric fever) remains a burden in developing countries and a major health problem in Southern and Southeastern Asia. Salmonella typhi (S. typhi), the causative agent of typhoid fever, is a gram-negative, motile, rod-shaped, facultative anaerobe and solely a human pathogen with no animal reservoir. Infection of S. typhi can cause fever, abdominal pain and many worsenonspecific symptoms, including gastrointestinal symptoms suchas nausea, vomiting, constipation, and diarrhea. Chloramphenicol, ampicillin,and cotrimoxazole were the first-recommended antibiotics in treating typhoid fever. In the last two decades though, these three traditional drugs started to show resistance and developed multidrug resistance (MDR) S. typhi strains. In many parts of the world, the changing modes ofpresentation and the development of MDR have made typhoid fever increasingly difficult to treat.The use of first-line antimicrobials had been recommended to be fluoroquinolone as a replacement. However, this wassoonfollowedbyreportsof isolates ofS. typhi showing resistancetofluoroquinolones as well. These antimicrobial resistance problems in typhoid fever have been an alarming situation ever since and need to be taken seriously or else typhoid fever will no longer be taken care completely by administering antibiotics.

    Yellow fever is an acute infectious disease caused by prototype virus of the genus Flavivirus. It is endemic in Africa and South America where it represents a serious public health problem causing epidemics of hemorrhagic fever with mortality rates ranging from 20% to 50%. There is no available antiviral therapy and vaccination is the primary method of disease control. Although the attenuated vaccines for yellow fever show safety and efficacy it became necessary to develop a new yellow fever vaccine due to the occurrence of rare serious adverse events, which include visceral and neurotropic diseases. The new inactivated vaccine should be safer and effective as the existing attenuated one. In the present study, the immunogenicity of an inactivated 17DD vaccine in C57BL/6 mice was evaluated. The yellow fever virus was produced by cultivation of Vero cells in bioreactors, inactivated with β-propiolactone, and adsorbed to aluminum hydroxide (alum). Mice were inoculated with inactivated 17DD vaccine containing alum adjuvant and followed by intracerebral challenge with 17DD virus. The results showed that animals receiving 3 doses of the inactivated vaccine (2 μg/dose) with alum adjuvant had neutralizing antibody titers above the cut-off of PRNT50 (Plaque Reduction Neutralization Test). In addition, animals immunized with inactivated vaccine showed survival rate of 100% after the challenge as well as animals immunized with commercial attenuated 17DD vaccine.

    Q fever is an ubiquitous zoonosis caused by Coxiella burnetii. Its tropism for the uterus is a potential source of obstetric complications. We describe the obstetric consequences of Q fever diagnosed during pregnancy from a series of cases. When an antenatal diagnosis was made, antibiotic therapy with roxithromycin (Rulid(®)) was started until delivery. Between 2007 and 2012, 30 patients were treated for Q fever diagnosed during pregnancy, i.e. 1.9 cases per 1000 people. The most common reasons for performing serology was intrauterine growth retardation, preterm labor and oligoamnios. Q fever was diagnosed as acute and chronic in 26 and 4 cases, respectively. Progression to chronic disease occurred in 8 % of acute forms of the diseases. The prevalence of obstetric complications was 66 %, including 10 % foetal deaths, 31 % preterm delivery and 27 % low birthweight pregnancy is responsible for severe obstetric complications. It must be diagnosed early and its clinical forms known in order to start appropriate antibiotic therapy.

    Familial Mediterranean Fever (FMF) is a hereditary autoinflammatory disorder characterised by acute attacks of fever and serosal inflammation. FMF primarily affects Jewish, Armenian, Turkish, and Arab populations. The disease is accompanied by a marked decrease in quality of life due to the effects of attacks and subclinical inflammation in the attack-free periods. Untreated or inadequately treated patients run the risk of amyloidosis, which is an important cause of morbidity and mortality. In this review, the current information available on FMF is summarised.

    3 months, in one instance, with a remittence during the 3rd to 5th weeks, to the acute high fever (106°F.) of 1 day's duration in the fatally infected monkey, No. 25. The more usual reaction, however, is an irregular course of moderate fever with one or more periods of high temperature (105°). Bartonella bacilliformis was constantly demonstrated, both microscopically and by culture tests, in the lymph glands of animals sacrificed 2 to 3 months after inoculation, and in two of three instances it was present also in the spleen, bone marrow, and heart blood. In the case of M. rhesus 6, which died 26 days after inoculation, the microorganism was obtained also in culture from the lymph glands, spleen, and heart blood taken at autopsy. In the other animal which died, a terminal bactelial infection, while not obscuring the effects of the Bartonella infection, made it impossible to isolate the parasite from either blood or tissues. The skin lesions, whether of the nodular type, induced by introduction of the virus intradermally or by application to the scarified skin, or of the miliary character occurring spontaneously as a result of systemic infection, always yielded cultures of Bartonella bacilliformis, and stained sections of such lesions revealed the parasites in large numbers in their characteristic situation in the endothelial cells. A chronic, systemic infection, in which the lymph glands are enlarged and Bartonella bacilliformis is present in the blood in high titer, may be induced by local inoculation, as shown in the case of M. rhesus 5. The local lesions induced in one instance by introduction of a passage strain, both intradermally and by scarification, attained within 2 months extraordinary size, the nodules arising at adjacent sites of inoculation on the right eyebrow having coalesced into a large pedunculated mass which overhung the eye. This type of reaction had not been observed hitherto in the course of the present study but has been described by earlier

    1. Saimiri sciureus has been infected with yellow fever virus, both by the inoculation of infectious blood and by the bites of infective mosquitoes. Some of the monkeys have died, showing lesions, including hepatic necrosis, suggesting yellow fever as seen in human beings and in rhesus monkeys. Virus has been transferred back to M. rhesus from infected Saimiri both by blood inoculation and by mosquito bites. The virus undoubtedly has been maintained through four direct passages in Saimiri. Reinoculations of infectious material into recovered monkeys have not given rise to invasion of the blood stream by virus. Sera from recovered animals have protected M. rhesus against the inoculation of virus. 2. It has been possible to pass the virus to and from Ateleus ater by the injection of blood or liver and by the bites of mosquitoes. The livers from two infected animals have shown no necrosis. The serum from one recovered monkey proved to be protective for M. rhesus. 3. Only three out of twelve Lagothrix lagotricha have reacted to yellow fever virus by a rise in temperature. Probably none have died as a result of the infection. In only one instance has the virus been transferred back to M. rhesus. The sera of recovered animals have had a protective action against yellow fever virus. PMID:19869721

    Dengue fever is caused by a flavivirus. This infection is endemic in the tropics and warm temperate regions of the world. Ocular manifestations of dengue fever include subconjunctival, vitreous, and retinal haemorrhages; posterior uveitis; optic neuritis; and maculopathies, haemorrhage, and oedema. However anterior ischemic optic neuropathy is a rare presentation. Optic nerve ischemia most frequently occurs at the optic nerve head, where structural crowding of nerve fibers and reduction of the vascular supply may combine to impair perfusion to a critical degree and produce optic disc oedema. Here we present a case of anterior ischemic optic neurapathy associated with dengue fever.

    Endothelial dysfunction has previously been reported in children with a history of Kawasaki disease, but the determinants of endothelial function in Kawasaki disease patients are still unknown. In this study, we investigated endothelial function in Kawasaki disease patients and attempted to identify risk factors for persistent endothelial dysfunction. Using high-resolution ultrasound, we measured the percent flow-mediated dilatation, an arterial response to reactive hyperemia, to evaluate endothelial function in 67 patients with a history of Kawasaki disease and 28 age- and sex-matched control subjects. We divided the Kawasaki disease patients into a group with impaired endothelial function (the percent flow-mediated dilatation below -2 standard deviations of the control group) and a group with normal endothelial function (the percent flow-mediated dilatation more than -2 standard deviations of control). Logistic multiple regression analysis was performed to identify independent predictors of impaired endothelial function. In Kawasaki disease patients, the percent flow-mediated dilatation was significantly lower than in the control subjects (9.8±3.6%, compared with 13.1±3.4%, pKawasaki disease patients (3 patients with coronary artery lesions and 10 patients without coronary artery lesions), the percent flow-mediated dilatation was below -2 standard deviations of control. Logistic multiple regression analysis showed that a febrile period of longer than 10 days during the acute phase was the significant risk factor for endothelial dysfunction (odds ratio: 8.562; 95% confidence interval: 1.366-53.68). Presence of coronary artery lesions was not a determinant of endothelial dysfunction. Systemic endothelial dysfunction exists in children with a history of Kawasaki disease, and a febrile period of longer than 10 days during the acute phase is an independent predictor of endothelial dysfunction irrespective of coronary artery involvement.

    Full Text Available African swine fever (ASF is a devastating disease of domestic pigs. It is a socioeconomically important disease, initially described from Kenya, but subsequently reported in most Sub-Saharan countries. ASF spread to Europe, South America and the Caribbean through multiple introductions which were initially eradicated—except for Sardinia—followed by re‑introduction into Europe in 2007. In this study of ASF within the Democratic Republic of the Congo, 62 domestic pig samples, collected between 2005–2012, were examined for viral DNA and sequencing at multiple loci: C-terminus of the B646L gene (p72 protein, central hypervariable region (CVR of the B602L gene, and the E183L gene (p54 protein. Phylogenetic analyses identified three circulating genotypes: I (64.5% of samples, IX (32.3%, and XIV (3.2%. This is the first evidence of genotypes IX and XIV within this country. Examination of the CVR revealed high levels of intra-genotypic variation, with 19 identified variants.

    Full Text Available Enteric fever is a common infectious disease of the tropical world, about 80% of these cases occur in Asian countries. Enteric fever presenting with isolated cerebellar ataxia or nephritis is rare. We report three cases of enteric fever that presented with these complications. Isolated cerebellar ataxia usually occurs in the second week, whereas in our cases it presented within first four days of fever. The common complications of enteric fever related to the urinary tract are cystitis, pyelitis, and pyelonephritis. Glomerulonephritis is uncommon. Most patients with enteric glomerulonephritis present with acute renal failure, hypertensive encephalopathy, or nephritic syndrome. In comparison, our case had milder manifestations. All three patients were treated with parenteral ceftriaxone and showed a prompt recovery.

    Aberrant epigenetics play a key role in the onset and progression of acute myeloid leukemia (AML). Herein we report in silico modelling based development of a novel, protein-vorinostat nanomedicine exhibiting selective and superior anti-leukemic activity against heterogeneous population of AML patient samples (n=9), including refractory and relapsed cases, and three representative cell lines expressing CD34(+)/CD38(-) stem cell phenotype (KG-1a), promyelocytic phenotype (HL-60) and FLT3-ITD mutation (MV4-11). Nano-vorinostat having ~100nm size exhibited enhanced cellular uptake rendering significantly lower IC50 in AML cell lines and patient samples, and induced enhanced HDAC inhibition, oxidative injury, cell cycle arrest and apoptosis compared to free vorinostat. Most importantly, nanomedicine showed exceptional single-agent activity against the clonogenic proliferative capability of bone marrow derived leukemic progenitors, while remaining non-toxic to healthy bone marrow cells. Collectively, this epigenetics targeted nanomedicine appears to be a promising therapeutic strategy against various French-American-British (FAB) classes of AML. Through the use of a protein-vorinostat agent, exceptional single-agent activity was demonstrated against the clonogenic proliferative capability of bone marrow derived leukemic progenitors, while remaining non-toxic to healthy bone marrow cells. The studied epigenetics targeted nanomedicine approach is a promising therapeutic strategy against various French-American-British classes of acute myeloid leukemia. © 2014 Elsevier Inc.

    Positive serology for dengue and/or scrub typhus infection with/without positive malarial smear (designated as mixed or co-infection) is being increasingly observed during epidemics of acute undifferentiated febrile illnesses (AUFIs). We planned to study the clinical and biochemical spectrum of co-infections with Plasmodium sp., dengue virus and scrub typhus and compare these with mono-infection by the same organisms. During the period from December 2012 to December 2013, all cases presenting with AUFIs to a single medical unit of a referral centre in Garhwal region of the north Indian state of Uttarakhand were retrospectively selected and categorised aetiologically as co-infections, malaria, dengue or scrub typhus. The groups thus created were compared in terms of demographic, clinical, biochemical and outcome parameters. The co-infection group (n = 49) was associated with milder clinical manifestations, fewer, milder and non-progressive organ dysfunction, and lesser need for intensive care, mechanical ventilation and dialysis as compared to mono-infections. When co-infections were sub-grouped and compared with the relevant mono-infections, there were differences in certain haematological and biochemical parameters; however, this difference did not translate into differential outcomes. Scrub typhus mono-infection was associated with severe disease in terms of both morbidity and mortality. Malaria, dengue and scrub typhus should be routinely tested in all patients with AUFIs. Co-infections, whether true or due to serological cross-reactivity, appear to be a separate entity so far as presentation and morbidity is concerned. Further insight is needed into the mechanism and identification of the protective infection.

    Although there are many postoperative febrile causes, surgical-site infection has always been considered as one of the major causes, but it should be excluded; we encountered many patients who showed delayed postoperative fever that was not related to wound infection after spinal surgery. We aimed to determine the incidence of delayed postoperative fever and its characteristics after spinal surgery, and to analyze the causal factors. A total of 250 patients who underwent any type of spinal surgery were analyzed. We determined febrile patients as those who did not show any fever until postoperative day 3, and those who showed a fever with an ear temperature of greater than 37.8°C at 4 days after surgery. We collected patient data including age, sex, coexistence of diabetes mellitus or hypertension, smoking history, location of surgical lesion (e.g., cervical, thoracic, lumbar spine), type of surgery, surgical approach, diagnosis, surgical level, presence of revision surgery, operative time, duration of administration of prophylactic antibiotics, and the presence of transfusion during the perioperative period, with a chart review. There were 33 febrile patients and 217 afebrile patients. Multivariate logistic regression showed that surgical approach (i.e., posterior approach with anterior body removal and mesh graft insertion), trauma and tumor surgery compared with degenerative disease, and long duration of surgery were statistically significant risk factors for postoperative nonpathologic fever. We suggest that most spinal surgeons should be aware that postoperative fever can be common without a wound infection, despite its appearance during the late acute or subacute period.

    Chikungunya fever, caused by “Chikungunya virus,” is an arbovirus disease transmitted by the bite of infected mosquitoes belonging to the genus Aedes. Chikungunya fever epidemics have been reported from several countries around the world. The disease that was silent for nearly 32 years re-emerged in the October 2005 outbreak in India that is still ongoing. The incubation period ranges from 3 to 12 days. The onset is usually abrupt and the acute stage is characterized by sudden onset with high-grade fever, severe arthralgias, myalgias, and skin rash. Swollen tender joints and crippling arthritis are usually evident. In the chronic stage, relapses that include sensation of fever, asthenia, exacerbation of arthralgias, inflammatory polyarthritis, and stiffness may be evident. Neurological, ocular, and mucocutaneous manifestations have also been described. Chronic arthritis may develop in about 15% of the patients. Viral culture is the gold standard for the diagnosis of Chikungunya fever. Reverse transcription polymerase chain reaction and real-time loop-mediated isothermal amplification have also been found to be useful. Serodiagnostic methods for the detection of immunoglobulin M and immunoglobulin G antibodies against Chikungunya virus are more frequently used. Chikungunya is a self-limiting disease; however, severe manifestations such as meningoencephalitis, fulminant hepatitis, and bleeding manifestations may sometimes be life-threatening. Treatment is symptomatic and supportive. Prevention by educating the community and public health officials, vector control measures appear to be the best approach at controlling Chikungunya fever as no commercially available vaccine is available for public use in India for this condition presently.

The incidence of dengue has multiplied many times over the last five decades at an alarming rate. In the endemic areas, waves of infection occur in epidemics, with thousands of individuals affected, creating a huge burden on the limited resources of a country's health care system. While the illness passes off as a simple febrile episode in many, a few have a severe illness marked by hypovolemic shock and bleeding. Iatrogenic fluid overload in the management may further complicate the picture. In this severe form dengue can be fatal. Tackling the burden of dengue is impeded by several issues, including a lack of understanding about the exact pathophysiology of the infection, inability to successfully control the vector population, lack of specific therapy against the virus, and the technical difficulties in developing a vaccine. This review provides an overview on the epidemiology, natural history, management strategies, and future directions for research on dengue, including the potential for development of a vaccine.Keywords: dengue, treatment, fluid resuscitation

    . Intermediate yellow fever--a term coined to define epidemia which do not correspond exactly to urban yellow fever. The cycle involves men and monkeys through wild vectors as Aedes furcifer but also through Aedes aegypti and the mortality rate is much lower than for urban epidemics. In urban yellow fever, man is the only vertebrate host involved in the circulation of the virus, the vector being generally Aedes aegypti. This vector maintains a selective pressure, increasing the transmission of virus capable of producing high viremia in man. In the selvatic cycles, two cycles can be distinguished: one of maintenance which does not increase the quantity of virus in circulation and one of amplification which does increase this quantity. As we shall see, it develops into an epizootic form but also in an epidemic form in man. When the decrease in yellow fevers across Africa is considered, it appears that all major epidemics occur in West Africa inspite of the presence of wild cycles of the yellow fever virus in Central and East Africa. For the rare epidemics that have occurred there, the vector has never been Aedes aegypti. In a recent outbreak in Kenya, the vector was Aedes bromeliae. The examination of part of the gene encoding for envelope protein showed the presence of two geographical types corresponding to West-Africa and Central East-Africa. Clinically speaking, yellow fever is an haemorrhagic fever with hepatitis similar to other haemorrhagic fevers such as Rift Valley fever. When, in 1987, an outbreak of haemorrhagic fever occurred in southern Mauritania, for several days it was thought to be yellow fever. Four days later, the diagnosis was corrected by isolating and identifying the virus as that of Rift Valley fever (RVFV). RVFV causes several pathogenic syndromes in human beings: acute febrile illness, haemorrhagic fever, haemorrhagic fever with hepatitis, nervous syndromes or ocular disease. Mortality rate was high for haemorrhagic fever with hepatitis, reaching 36

    under regular penicillin prophylaxis. The levels of ASO in ARF were also significantly higher than in patients with isolated chorea, recurrent oropharyngeal infections or juvenile idiopathic arthritis (P = 0.0025, when age-matched samples of these groups were compared. The test’s sensitivity was 73.3% and the specificity was 57.6%, and it was calculated taking into account the upper limit of normality at 320 IU/ml, as well as the established diagnosis of ARF. The test’s specificity and positive predictive value increased with rising or higher titers, being higher with titers above 960 UI/ml. CONCLUSION: this reappraisal of ASO profile in ARF patients indicates a remarkable response during the acute phase, and that points to the extent to which ASO levels may differentiate ARF from other diseases with high levels of ASO antibodies, as coincidental but unrelated streptococcal infection or chronic arthritis flareup.

    Full Text Available Introduction: Dengue, an acute viral disease transmitted by Aedes mosquitoes, is highly endemic in many tropical and subtropical areas of the world. Neurological complications of dengue infection have been observed more frequently in the recent past and some studies highlighted varied neurological complications arising in the course of dengue illness. In this retrospective study, we report various neurological complications observed during the last 2 years in patients of dengue fever. Materials and Methods: The patients presenting with neurological complications with positive serology (IgM antibody for dengue infection were consecutively recruited from the Department of Neurology/Medicine from a tertiary center of Lucknow, India. These patients were subjected to a detailed clinical evaluation, laboratory assessment including blood count, hematocrit, coagulation parameters, biochemical assays, serology for dengue fever, enzyme-linked immunosorbent assay for human immunodeficiency virus and other relevant investigations. Results: Twenty-six patients with neurological complications associated with confirmed dengue infection were observed during the last 2 years. Eighteen of these patients were male. Of the 26 patients, 10 patients were suffering from brachial neuritis, four patients had encephalopathy, three patients were consistent with the diagnosis of Guillain Barre syndrome, three patients had hypokalemic paralysis associated with dengue fever and two patients had acute viral myositis. Opsoclonus-myoclonus syndrome was diagnosed in two patients, myelitis in one patient and acute disseminated encephalo-myelitis also in one patient. Conclusion: Dengue fever was associated with widespread neurological complications. Brachial neuritis and opsoclonus-myoclonus syndrome were observed for the first time in this study.

    Background Investigations were conducted by the authors to explore an outbreak of viral hemorrhagic fever (VHF) reported in 2010 from Al-Mukalla city, the capital of Hadramout in Yemen. Methods From 15–17 June 2010, the outbreak investigation period, specimens were obtained within 7 days after onset of illness of 18 acutely ill patients hospitalized with VHF and 15 household asymptomatic contacts of 6 acute cases. Additionally, 189 stored sera taken from acutely ill patients with suspected VHF hospitalized in the preceding 12 months were obtained from the Ministry of Health of Yemen. Thus, a total of 222 human specimens were collected; 207 specimens from acute cases and 15 specimens from contacts. All samples were tested with RT-PCR for dengue (DENV), Alkhumra (ALKV), Rift Valley Fever (RVFV), Yellow Fever (YFV), and Chikungunya (CHIKV) viruses. Samples were also tested for DENV IgM, IgG, and NS1-antigen. Medical records of patients were reviewed and demographic, clinical, and laboratory data was collected. Results Of 207 patients tested, 181 (87.4%) patients were confirmed to have acute dengue with positive dengue NS1-antigen (97 patients, 46.9%) and/or IgM (163 patients, 78.7%). Of the 181 patients with confirmed dengue, 100 (55.2%) patients were IgG-positive. DENV RNA was detected in 2 (1%) patients with acute symptoms; both samples were molecularly typed as DENV type 3. No other VHF viruses were detected. For the 15 contacts tested, RT-PCR tests for the five viruses were negative, one contact was dengue IgM positive, and another one was dengue IgG positive. Of the 181 confirmed dengue patients, 120 (66.3%) patients were males and the median age was 24 years. The most common manifestations included fever (100%), headache (94.5%), backache (93.4%), malaise (88.4%), arthralgia (85.1%), myalgia (82.3%), bone pain (77.9%), and leukopenia (76.2%).

Of the 181 confirmed dengue patients, 120 (66.3%) patients were males and the median age was 24 years. The most common manifestations included fever (100%), headache (94.5%), backache (93.4%), malaise (88.4%), arthralgia (85.1%), myalgia (82.3%), bone pain (77.9%), and leukopenia (76.2%). Two (1.1%) patients died. DENV-3 was confirmed to be the cause of an outbreak of VHF in Al-Mukalla. It is important to use both IgM and NS1-antigen

    Full Text Available Abstract Background Classical swine fever virus (CSFV belongs to the genus Pestivirus within the family Flaviviridae. Virulent strains of classical swine fever virus (CSFV cause severe disease in pigs characterized by immunosuppression, thrombocytopenia and disseminated intravascular coagulation, which causes significant economic losses to the pig industry worldwide. Methods To reveal proteomic changes in swine serum during the acute stage of lethal CSFV infection, 5 of 10 pigs were inoculated with the virulent CSFV Shimen strain, the remainder serving as uninfected controls. A serum sample was taken at 3 days post-infection from each swine, at a stage when there were no clinical symptoms other than increased rectal temperatures (≥40°C. The samples were treated to remove serum albumin and immunoglobulin (IgG, and then subjected to two-dimension differential gel electrophoresis. Results Quantitative intensity analysis revealed 17 protein spots showing at least 1.5-fold quantitative alteration in expression. Ten spots were successfully identified by MALDI-TOF MS or LTQ MS. Expression of 4 proteins was increased and 6 decreased in CSFV-infected pigs. Functions of these proteins included blood coagulation, anti-inflammatory activity and angiogenesis. Conclusion These proteins with altered expression may have important implications in the pathogenesis of classical swine fever and provide a clue for identification of biomarkers for classical swine fever early diagnosis.

    Rift Valley fever virus is an emerging mosquito-borne virus that causes infections in animals and human beings in Africa and the Arabian Peninsula. Outbreaks of Rift Valley fever lead to mass abortions in livestock, but such abortions have not been identified in human beings. Our aim was to investigate the cause of miscarriages in febrile pregnant women in an area endemic for Rift Valley fever. Pregnant women with fever of unknown origin who attended the governmental hospital of Port Sudan, Sudan, between June 30, 2011, and Nov 17, 2012, were sampled at admission and included in this cross-sectional study. Medical records were retrieved and haematological tests were done on patient samples. Presence of viral RNA as well as antibodies against a variety of viruses were analysed. Any association of viral infections, symptoms, and laboratory parameters to pregnancy outcome was investigated using Pearson's χ 2 test. Of 130 pregnant women with febrile disease, 28 were infected with Rift Valley fever virus and 31 with chikungunya virus, with typical clinical and laboratory findings for the infection in question. 15 (54%) of 28 women with an acute Rift Valley fever virus infection had miscarriages compared with 12 (12%) of 102 women negative for Rift Valley fever virus (pInternational Development Cooperation Agency, the County Council of Västerbotten, and the Faculty of Medicine, Umeå University.

    Full Text Available 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.

    Dengue fever, rickettsial diseases, and Q fever are acute febrile illnesses with similar manifestations in tropical areas. Early differential diagnosis of scrub typhus, murine typhus, and Q fever from dengue fever may be made by understanding the distinguishing clinical characteristics and the significance of demographic and weather factors. We conducted a retrospective study to identify clinical, demographic, and meteorological characteristics of 454 dengue fever, 178 scrub typhus, 143 Q fever, and 81 murine typhus cases in three Taiwan hospitals. Case numbers of murine typhus and Q fever correlated significantly with temperature and rainfall; the scrub typhus case number was only significantly related with temperature. Neither temperature nor rainfall correlated with the case number of dengue fever. The rarity of dengue fever cases from January to June in Taiwan may be a helpful clue for diagnosis in the area. A male predominance was observed, as the male-to-female rate was 2.1 for murine typhus and 7.4 for Q fever. Multivariate analysis revealed the following six important factors for differentiating the rickettsial diseases and Q fever group from the dengue fever group: fever ≥8 days, alanine aminotransferase > aspartate aminotransferase, platelets >63,000/mL, C-reactive protein >31.9 mg/L, absence of bone pain, and absence of a bleeding syndrome. Understanding the rarity of dengue in the first half of a year in Taiwan and the six differentiating factors may help facilitate the early differential diagnosis of rickettsial diseases and Q fever from dengue fever, permitting early antibiotic treatment.

    Acute undifferentiated fever (AUF) poses a diagnostic challenge due to the variety of possible aetiologies. While the majority of AUFs resolve spontaneously, some cases become prolonged and cause significant morbidity and mortality, necessitating improved diagnostic methods. This study evaluated the utility of deep sequencing in fever investigation. DNA and RNA were isolated from plasma/sera of AUF cases being investigated at Cairns Hospital in northern Australia, including eight control samples from patients with a confirmed diagnosis. Following isolation, DNA and RNA were bulk amplified and RNA was reverse transcribed to cDNA. The resulting DNA and cDNA amplicons were subjected to deep sequencing on an Illumina HiSeq 2000 platform. Bioinformatics analysis was performed using the program Kraken and the CLC assembly-alignment pipeline. The results were compared with the outcomes of clinical tests. We generated between 4 and 20 million reads per sample. The results of Kraken and CLC analyses concurred with diagnoses obtained by other means in 87.5 % (7/8) and 25 % (2/8) of control samples, respectively. Some plausible causes of fever were identified in ten patients who remained undiagnosed following routine hospital investigations, including Escherichia coli bacteraemia and scrub typhus that eluded conventional tests. Achromobacter xylosoxidans, Alteromonas macleodii and Enterobacteria phage were prevalent in all samples. A deep sequencing approach of patient plasma/serum samples led to the identification of aetiological agents putatively implicated in AUFs and enabled the study of microbial diversity in human blood. The application of this approach in hospital practice is currently limited by sequencing input requirements and complicated data analysis.

    Dengue is a flavivirus of the genus arbovirus with four serotypes, from DEN 1 to DEN 4. There has been an increase in incidence of dengue infection in children in the tropics and subtropics. Dengue has a variable clinical presentation, with many patients being asymptomatic. Its clinical manifestations in children vary from fever and arthralgia to life-threatening dengue hemorrhagic fever and dengue shock syndrome. We describe MRI findings in children with neurological involvement including dengue encephalopathy, acute hypoxic injury and dengue encephalitis. Dengue encephalopathy is usually secondary to multisystem derangement such as shock, hepatitis, coagulopathy and concurrent bacterial infection and is relatively common. Dengue encephalitis from direct neuronal invasion is rare. Nonspecific changes are seen on brain MRI in dengue infection. Clinical and laboratory findings as well as outcome do not necessarily correspond with brain MRI findings.

    Fever of unknown origin (FUO) was originally defined as recurrent fever of 38.2 C or higher, lasting 2-3 weeks or longer, and undiagnosed after 1 week of hospital evaluation. The last criterion has undergone modification and is now generally interpreted as no diagnosis after appropriate inpatient or outpatient evaluation. The three major categories that account for the majority of fever of unknown origin (FUO) are infections, malignancies and non infectious inflammatory diseases. In this respect FOU in its original definition is clearly separated from nosocomial, post-operative and neutropenic fever, where acute infection is more common. Although in-vitro- or in-vivo-labelled white blood cells (WBCs) have a high diagnostic accuracy in the detection and exclusion of granulocytic pathology, these methods are only of limited value in patients with 'classic' FUO in establishing the final diagnosis due to the low prevalence of acute infection in this group. Labelled WBCs therefore seem to be more useful in patients with nosocomial, post-operative and neutropenic fever. 67 Ga citrate is the only commercially available gamma emitter in imaging acute, chronic, granulomatous and autoimmune inflammation and also various malignant diseases. Therefore 67 Ga citrate was for a long time considered to be the tracer of choice in the diagnostic work-up of FUO. The number of 67 Ga scans contributing to the final diagnosis was found to be higher than it has been reported for labelled WBCs. The positron emitter [ 18 F]-2-fluoro-2'-deoxy-D-glucose (FDG) have been systematically evaluated in the context of classic FUO by several groups within last 5 years. This data, although limited, indicate that FDG-imaging should considered as the most promising procedure in patients with undetermined fever. FDG-PT seems to be more sensitive than other techniques, offers a more rapid diagnosis without an increase of the patients radioactive burden. It is expected that the PET/CT technology will

    Dengue fever is a global disease with a spectrum of clinical manifestation ranging from mild febrile disease to a severe disease in the form of dengue hemorrhagic fever and dengue shock syndrome. Dengue virus is one viral hemorrhagic fever that exists in the Kingdom of Saudi Arabia in addition to Alkhurma (Alkhurma) Hemorrhagic Fever, Chikungunya virus, Crimean-Congo Hemorrhagic Fever, and Rift Valley Fever. The disease is limited to the Western and South-western regions of Saudi Arabia, where Aedes aegypti exists. The majority of the cases in Saudi Arabia had mild disease and is related to serotypes 1-3 but not 4. The prospect for Dengue virus control relies on vector control, health education, and possibly vaccine use. Despite extensive collaborative efforts between multiple governmental sectors, including Ministry of Health, Ministry of Municipalities and Rural Affairs, and Ministry of Water, dengue remains a major public health concern in the regions affected.

    Full Text Available Familial Mediterranean Fever is an autosomal recessive inherited disease with a course of autoinflammation, which is characterized by the episodes of fever and serositis. It affects the populations from Mediterranean basin. Genetic mutation of the disease is on MEFV gene located on short arm of Chromosome 16. The disease is diagnosed based on clinical evaluation. Amyloidosis is the most important complication. The only agent that decreases the development of amyloidosis and the frequency and severity of the episodes is colchicine, which has been used for about 40 years. In this review, we aimed to discuss especially the most recent advances about Familial Mediterranean Fever which is commonly seen in our population.

    The life and works of Dr Robert Robertson are reviewed set against the background of the extant British management of fevers during the latter 18th-century. Commencing in 1769, using the febrifuge Peruvian bark (cortex Peruvianus; Jesuit's Powder), he experimented and tested Peruvian bark mono-therapy protocols in the tropics in the cure and prevention of intermittent fever (predominantly malaria). His later work also showed the benefit of the bark in the acute care of developed continuous fevers (largely Ship Fever due to Epidemic Louse-borne Typhus Fever) in both the Temperate and Torrid Zones. In the realm of comparative statistics Robertson first demonstrated the safety and effectiveness of bark therapy against the dangerous depleting processes of the antiphlogistic regimen. He was the first to alert the Admiralty to the efficacy of bark in both the cure of acute fevers as well as a prophylactic in the tropics, and signalled the dangers of bloodletting in treating fevers of the tropics. He authored 13 books devoted to fevers outlining his theory of Febrile Infection and its treatment. The essay concludes with his role as the Physician-in-Charge of the Royal Hospital, Greenwich over a 28-year period, as an acknowledged expert in the small British group of 18th-century fever specialists.

    Viral etiologies of fever, including dengue, Chikungunya, influenza, rota and adeno viruses, cause major disease burden in tropical and subtropical countries. The lack of diagnostic facilities in developing countries leads to failure to estimate the true burden of such illnesses, and generally the diseases are underreported. These diseases may have similar symptoms with other causes of acute febrile illnesses including malaria and hence clinical diagnosis without laboratory tests can be difficult. This study aimed to identify viral etiologies as a cause of fever in children and their co-infections with malaria. A cross sectional study was conducted for 6 months at Kilosa district hospital, Tanzania. The participants were febrile children aged 2-13 years presented at the outpatient department. Diagnostic tests such as IgM and IgG ELISA, and PCR were used. A total of 364 patients were enrolled, of these 83(22.8%) had malaria parasites, 76 (20.9%) had presumptive acute dengue infection and among those, 29(38.2%) were confirmed cases. Dengue was more likely to occur in children ≥ 5 years than in Chikungunya infection was identified in 17(4.7%) of patients. We observed no presenting symptoms that distinguished patients with Chikungunya infection from those with dengue infection or malaria. Co-infections between malaria and Chikungunya, malaria and dengue fever as well as Chikungunya and dengue were detected. Most patients with Chikungunya and dengue infections were treated with antibacterials. Furthermore, our results revealed that 5(5.2%) of patients had influenza virus while 5(12.8%) had rotavirus and 2(5.1%) had adenovirus. Our results suggest that even though viral diseases are a major public health concern, they are not given due recognition as a cause of fever in febrile patients. Emphasis on laboratory diagnostic tests for proper diagnosis and management of febrile patients is recommended.

    This study documented whether patients diagnosed with acute rheumatic fever (ARF) in North Queensland, Australia, conformed to the 1992 Revised Jones Criteria (RJC). The authors aimed to determine whether inclusion of subclinical carditis (SCC) and monarthritis as major manifestations and a low-grade temperature as a minor manifestation in the RJC are justified in this population. A retrospective review of patients in whom the diagnosis of ARF relied on the experience of clinicians and who were admitted to the Townsville and Cairns Base Hospitals between 1997 and 2007 was undertaken. Of the 98 cases reviewed, 71.4% satisfied the RJC. Modification of the RJC increased the rate of criteria satisfaction to 91.8%. On presentation, 27 patients had SCC. Of the patients with SCC followed up, 70.5% had long-term valvular consequences. In populations endemic for ARF, monarthritis, SCC and a low-grade temperature should be included in the RJC.

    Viral hemorrhagic fevers (VHFs) caused by Ebola, Marburg and Lassa viruses often manifest as multiple organ dysfunction and hemorrhagic shock with high mortality. These viruses target numerous cell types, including monocytes and dendritic cells, which are primary early targets that mediate critical pathogenetic processes. This review focuses on fibroblastic reticular cells (FRCs), another prevalent infected cell type that is known as a key regulator of circulatory and immune functions. Viral infection of FRCs could have debilitating effects in secondary lymphoid organs and various other tissues. FRCs may also contribute to the spread of these deadly viruses throughout the body. Here, we review the salient features of these VHFs and the biology of FRCs, emphasizing the potential role of these cells in VHFs and the rapid deterioration of immune and hemovascular sytems that are characteristic of such acute infections.

    To observe the pattern and mortality of Congo-Crimean Hemorrhagic Fever (CCHF) in Balochistan. Two hundred and twenty-six febrile patients with bleeding of sudden onset, with initial signs and symptoms including headache, high fever, back pain, joint pain, stomach pain, vomiting, red eyes, flushed face, red throat and petechiae on the palate of both sexes were screened for CCHF over a period of 10 years. Clinical criteria for initial diagnosis directed the subsequent diagnostic work-up. The ages of these patients ranged from 7 years to 74 years. Sixty-three percent of these patients were positive for CCHF. Males were 68% of the total patients. Over the years, CCHF showed a gradual increase ranging from 43% to 80%. Total mortality was 15%, all being secondary cases. Death was not observed in primary CCHF cases. In this study, suspicion of viral hemorrhagic fever was raised in 62% cases at the time of admission and the patients were immediately isolated, noninvasive procedures were instigated and barrier nursing was implemented. None of the family and hospital staff members who had close contact with the patient became ill, while those who were not suspected initially (38%) infected the health care workers and the family members. Although CCHF is rare, this study stresses the need for proper health facilities in Pakistan and to include VHF (viral hemorrhagic fevers) in the differential diagnosis of unexplained fever with hemorrhagic tendencies of sudden onset.

    The majority of patients with acute febrile jaundice (>95%) identified through a yellow fever surveillance program in the Democratic Republic of Congo (DRC) test negative for antibodies against yellow fever virus. However, no etiological investigation has ever been carried out on these patients. Here, we tested for hepatitis A (HAV), hepatitis B (HBV), hepatitis C (HCV), hepatitis D (HDV), and hepatitis E (HEV) viruses, all of which can cause acute febrile jaundice, in patients included in the yellow fever surveillance program in the DRC. On a total of 498 serum samples collected from suspected cases of yellow fever from January 2003 to January 2012, enzyme-linked immunosorbent assay (ELISA) techniques were used to screen for antibodies against HAV (IgM) and HEV (IgM) and for antigens and antibodies against HBV (HBsAg and anti-hepatitis B core protein [HBc] IgM, respectively), HCV, and HDV. Viral loads and genotypes were determined for HBV and HVD. Viral hepatitis serological markers were diagnosed in 218 (43.7%) patients. The seroprevalences were 16.7% for HAV, 24.6% for HBV, 2.3% for HCV, and 10.4% for HEV, and 26.1% of HBV-positive patients were also infected with HDV. Median viral loads were 4.19 × 10 5 IU/ml for HBV (range, 769 to 9.82 × 10 9 IU/ml) and 1.4 × 10 6 IU/ml for HDV (range, 3.1 × 10 2 to 2.9 × 10 8 IU/ml). Genotypes A, E, and D of HBV and genotype 1 of HDV were detected. These high hepatitis prevalence rates highlight the necessity to include screening for hepatitis viruses in the yellow fever surveillance program in the DRC. Copyright © 2017 Makiala-Mandanda et al.

    Dengue viruses (DENV) cause 50-100 million cases of acute febrile disease every year, including 500,000 reported cases of dengue hemorrhagic fever (DHF) and dengue shock syndrome (DSS). Viral factors have been proposed to influence the severity of the disease, but markers of virulence have never been identified on DENV. Three DENV serotype-1 isolates from the 2007 epidemic in Cambodia that are derived from patients experiencing the various clinical forms of dengue were characterized both phenotypically and genetically. Phenotypic characteristics in vitro, based on replication kinetics in different cell lines and apoptosis response, grouped isolates from DF and DHF patients together, whereas the virus isolate from a DSS patient showed unique features: a lower level of replication in mammalian cells and extensive apoptosis in mosquito cells. Genomic comparison of viruses revealed six unique amino acid residues in the membrane, envelope, and in non-structural genes in the virus isolated from the DSS patient.

    Dengue infection demonstrates a wide spectrum of clinical manifestations from mild disease (dengue fever) to severe dengue hemorrhagic fever, but the immunopathogenic mechanisms involved in disease severity are not clear. Differentially expressed genes associated to immune response were identified from peripheral blood mononuclear cells of Colombian children with dengue fever and dengue hemorrhagic fever. Microarray analysis was used as a tool to establish and compare transcriptional profiles of peripheral blood mononuclear cells of six children in acute phase of dengue fever and dengue hemorrhagic fever. The commercial gene chip used was Affymnetrix GeneChip HG_U133_Plus_2. Dengue hemorrhagic fever patients expressed interleukin 6, chemokines, complement proteins and pentraxin 3, along with the lymphocyte inhibitors lymphocyte-activation gene 3 and cathepsin L1. An interaction model for these genes showed tissue factor playing a central role in the network generated. In contrast, dengue fever patients expressed cytokines, complement and the leukotrienes inhibitors lactotransferrin, C1 inhibitor, and leukotriene-B (4-omega-hydroxylase 2). These results indicate that in dengue fever, cytokine and complement inhibitors are able to limit endothelial damage and prevent increases in vascular permeability, whereas dengue- hemorrhagic fever patients have immune cell dysfunction and unregulated complement and cytokine action. This leads to "hypercoagulation" and endothelial damage, thereby increasing disease severity. Verification of the pathogenic role of the identified molecules will contribute to understanding of dengue pathogenesis and lead to rational development of therapeutic drugs.

    Early studies on prolonged fever date back to the 1960s. Fifty years later, prolonged unexplained fever remains a diagnostic challenge to the general internists. Although the aetiologies of prolonged fevers have not changed much in the general population, the distribution between the various causes is not the same anymore. A regular decrease in infectious and neoplastic causes is noticed whatever the age. Prolonged fevers related to inflammatory disorders and fevers that remain of unknown origin still represent approximately 30 to 50% of the cases. In the young adult population, as in the older patients, prolonged fevers can be attributed to four groups: infection, inflammation, neoplasic and other aetiologies (including drug-related fevers). In the young adult population, the management of prolonged fever presents some specific issues that are the purpose of this review coupled with our own experience. The prognosis of undiagnosed prolonged fever is usually favourable, as a life-threatening aetiology is exceptionally diagnosed during the follow-up if the initial management was complete and accurate.

    Vitamin D could modulate pathways leading to dengue hemorrhagic fever/dengue shock syndrome (DHF/DSS). We examined the associations of serum total 25-hydroxy vitamin D [25(OH)D] and vitamin D binding protein (VDBP) concentrations in patients with uncomplicated dengue fever (DF) with risk of progression to DHF/DSS. In a case-control study nested in a cohort of DF patients who were followed during the acute episode in Bucaramanga, Colombia, we compared 25(OH)D and VDBP at onset of fever between 110 cases who progressed to DHF/DSS and 235 DF controls who did not progress. 25(OH)D concentrations were also compared between the acute sample and a sample collected >1 year post-convalescence in a subgroup. Compared with 25(OH)D ⩾75 nmol/l, adjusted odds ratios (95% CI) for progression were 0·44 (0·22-0·88) and 0·13 (0·02-1·05) for 50 to 75 nmol/l (vitamin D insufficiency) and <50 nmol/l (vitamin D deficiency), respectively (P, trend = 0·003). Mean 25(OH)D concentrations were much lower post-convalescence compared with the acute episode, regardless of case status. Compared with controls, mean VDBP was non-significantly lower in cases. We conclude that low serum 25(OH)D concentrations in DF patients predict decreased odds of progression to DHF/DSS.

    The role of acute arterial hypertension in acute pulmonary edema (APE) as an associated or triggering phenomenon has been poorly investigated and is relevant to patient management. This was a prospective observational study of clinical, electrocardiographic, and echocardiographic characteristics of patients with APE. Potential triggers, including acute coronary syndrome (ACS), rapid atrial fibrillation (AF) (≥ 120 bpm in AF), fever > 38°C or volume overload, isolated acute hypertension (systolic blood pressure ≥ 170 mm Hg), and unknown factors were investigated. There were 742 patients, 578 with coronary artery disease (78%), 116 with valvular heart disease or cardiomyopathy (16%), and 47 without identifiable heart disease (6%). ACS was present in 482 (65%) patients (silent in 154 of them), AF was present in 76 (10%) patients, fever/volume overload was present in 62 (8%) patients, acute hypertension was present in 50 (7%) patients, and no apparent trigger was seen in 72 (10%) patients. Admission hypertension occurred in 260 patients (35%): 155 (60%) with ACS (silent in 49 [32%]), 36 (14%) with AF, 19 (7%) with fever/volume overload, and 59 (19%) as an isolated trigger. Similar results were obtained when analyzing patients using coronary angiography (467 patients [63%]). Acute hypertension was present more frequently in patients with severe hypoventilation (arterial Pco 2 > 60 mm Hg) than in those without (57% vs 29%; P acute hypertension is often present but mainly as an associated/reactive phenomenon and seems favoured by severe hypoventilation. Silent myocardial ischemia/necrosis deserves systematic investigation because it is not rare that it may be the underlying cause of APE. Copyright © 2016 Canadian Cardiovascular Society.

    Fever is strongly associated with poor outcome after traumatic brain injury (TBI). We hypothesized that early fever is a direct result of brain injury and thus would be more common in TBI than in patients without brain injury and associated with inflammation. We prospectively enrolled patients with major trauma with and without TBI from a busy Level I trauma center intensive care unit (ICU). Patients were assigned to one of four groups based on their presenting Head Abbreviated Injury Severity Scale scores: multiple injuries: head Abbreviated Injury Scale (AIS) score greater than 2, one other region greater than 2; isolated head: head AIS score greater than 2, all other regions less than 3; isolated body: one region greater than 2, excluding head/face; minor injury: no region with AIS greater than 2. Early fever was defined as at least one recorded temperature greater than 38.3°C in the first 48 hours after admission. Outcome measures included neurologic deterioration, length of stay in the ICU, hospital mortality, discharge Glasgow Outcome Scale-Extended, and plasma levels of seven key cytokines at admission and 24 hours (exploratory). Two hundred sixty-eight patients were enrolled, including subjects with multiple injuries (n = 59), isolated head (n = 97), isolated body (n = 100), and minor trauma (n = 12). The incidence of fever was similar in all groups irrespective of injury (11-24%). In all groups, there was a significant association between the presence of early fever and death in the hospital (6-18% vs. 0-3%), as well as longer median ICU stays (3-7 days vs. 2-3 days). Fever was significantly associated with elevated IL-6 at admission (50.7 pg/dL vs. 16.9 pg/dL, p = 0.0067) and at 24 hours (83.1 pg/dL vs. 17.1 pg/dL, p = 0.0025) in the isolated head injury group. Contrary to our hypothesis, early fever was not more common in patients with brain injury, though fever was associated with longer ICU stays and death in all groups. Additionally, fever was

    Pathogenic mechanism of acute and chronic inflammation is connected to the increased production of superoxide anion, hydrogen peroxide, and other free radicals. Clinical role of lipid peroxidation (LPO) processes was studied in 38 patients in the age from 3 to 15 years old with different variants of Rheumatic Fever (RF). We have investigated the relationship between malonidialdehide (MDA) and RF. We measured the levels of MDA in the plasma in patients with acute rheumatic fever (ARF) and chronic rheumatic heart disease (CRHD). Our study revealed that the levels of MDA in patients with ARF are significantly higher than in patients with CRHD. These levels were also significantly higher in patients with history of disease for up to 2 years, than in patients with history longer than 2 years. Thus, the measurement of MDA in the plasma could be used as a laboratory test for relation of active state of rheumatic fever.

    Dengue is a leading public health problem with an expanding global burden. Dengue virus is also a significant cause of illness in international travelers with an increasing number of cases of dengue fever identified in travelers returning from dengue-endemic countries. This review focuses on the clinical illness of dengue infection in international travelers and provides a summary of the risk of infection for travelers, clinical features of infection, and an overview of dengue vaccines and their potential applicability to travelers. Four prospective studies of travelers to dengue-endemic destinations have shown that the dengue infection incidence ranges from 10.2 to 30 per 1,000 person-months. This varies according to travel destination and duration and season of travel. Dengue is also a common cause of fever in returned travelers, accounting for up to 16% of all febrile illnesses in returned travelers. Although the majority of infections are asymptomatic, a small proportion of travelers develop dengue hemorrhagic fever. The diagnosis of dengue in travelers requires a combination of serological testing for IgG and IgM together with either nucleic acid or NS1 antigen testing. Several vaccine candidates have now entered into clinical trials including ChimeriVax Dengue, which is currently in phase 3 trials, live-attenuated chimeric vaccines (DENV-DENV Chimera, Inviragen), live-attenuated viral vaccines, recombinant protein subunit vaccines, and DNA vaccines. Dengue infection in international travelers is not infrequent and may be associated with substantial morbidity. Furthermore, an accurate diagnosis of dengue in travelers requires the use of a combination of diagnostic tests. Although a vaccine is not yet available a number of promising candidates are under clinical evaluation. For now travelers should be provided with accurate advice regarding preventive measures when visiting dengue-endemic areas. © 2013 International Society of Travel Medicine.

    Full Text Available Chikungunya fever is a tropical vector-borne disease that has been spreading rapidly around the world during the last 10 years, and which has been usually misdiagnosed as dengue. Nowadays, this disease is increasing in Mexico, mainly in the southern and central zones of the country, being significantly more common in women, children and young adults (28% in < 20 years of age. The classical presentation includes fever, arthralgia, polyarthritis, back-pain, and skin rashes. Although symptoms and treatment are similar to those for dengue, there are key clinical features to differentiate these two diseases.

    There can be considerable overlap in the clinical presentation and laboratory features of dengue, malaria, and enteric fever, three important causes of fever in returned travelers. Routine laboratory tests including full blood examination (FBE), liver function tests (LFTs), and C-reactive protein (CRP) are frequently ordered on febrile patients, and may help differentiate between these possible diagnoses. Adult travelers returning to Australia who presented to the Royal Melbourne Hospital with confirmed diagnosis of dengue, malaria, or enteric fever between January 1, 2000 and March 1, 2013 were included in this retrospective study. Laboratory results for routine initial investigations performed within the first 2 days were extracted and analyzed. There were 304 presentations including 58 with dengue fever, 187 with malaria, and 59 with enteric fever, comprising 56% of all returned travelers with a febrile systemic illness during the study period. Significant findings included 9-fold and 21-fold odds of a normal CRP in dengue compared with malaria and enteric fever, respectively. The odds of an abnormally low white cell count (WCC) were also significantly greater in dengue versus malaria or enteric fever. Approximately one third of dengue presentations and almost half of the malaria presentations had platelet counts fever presentations. There is a wide differential diagnosis for imported fever, but the non-specific findings of a normal CRP with a low WCC and/or low platelet count may provide useful information in addition to clinical clues to suggest dengue over malaria or enteric fever. Further systematic prospective studies among travelers could help define the potential clinical utility of these results in assisting the clinician when deciding for or against commencement of empiric antimicrobial therapy while awaiting confirmatory tests. © 2014 International Society of Travel Medicine.

    2012-01-01

    Ebola viruses are the causative agents of a severe form of viral haemorrhagic fever in man, designated Ebola haemorrhagic fever, and are endemic in regions of central Africa. The exception is the species Reston Ebola virus, which has not been associated with human disease and is found in the Philippines. Ebola virus constitutes an important local public health threat in Africa, with a worldwide effect through imported infections and through the fear of misuse for biological terrorism. Ebola virus is thought to also have a detrimental effect on the great ape population in Africa. Case-fatality rates of the African species in man are as high as 90%, with no prophylaxis or treatment available. Ebola virus infections are characterised by immune suppression and a systemic inflammatory response that causes impairment of the vascular, coagulation, and immune systems, leading to multiorgan failure and shock, and thus, in some ways, resembling septic shock.

Diagnosis of acute acalculous cholecystitis remains difficult during neutropenic period. We present two acute myeloblastic leukemia patients that developed acute acalculous cholecystitis during chemotherapy-induced neutropenia. They suffered from fever, vomiting and acute pain in the epigastrium. Ultrasound demonstrated an acalculous gallbladder. Surgical management was required in one patient and conservative treatment was attempted in the other patient. None treatment measures were effective and two patients died. Acute acalculous cholecystitis is a serious complication in neutropenic patients. Earlier diagnosis could have expedited the management of these patients.

    Lassa fever is a viral haemorrhagic disease endemic to west Africa. No large-scale studies exist from Nigeria, where the Lassa virus (LASV) is most diverse. LASV diversity, coupled with host genetic and environmental factors, might cause differences in disease pathophysiology. Small-scale studies in Nigeria suggest that acute kidney injury is an important clinical feature and might be a determinant of survival. We aimed to establish the demographic, clinical, and laboratory factors associated with mortality in Nigerian patients with Lassa fever, and hypothesised that LASV was the direct cause of intrinsic renal damage for a subset of the patients with Lassa fever. We did a retrospective, observational cohort study of consecutive patients in Nigeria with Lassa fever, who tested positive for LASV with RT-PCR, and were treated in Irrua Specialist Teaching Hospital. We did univariate and multivariate statistical analyses, including logistic regression, of all demographic, clinical, and laboratory variables available at presentation to identify the factors associated with patient mortality. Of 291 patients treated in Irrua Specialist Teaching Hospital between Jan 3, 2011, and Dec 11, 2015, 284 (98%) had known outcomes (died or survived) and seven (2%) were discharged against medical advice. Overall case-fatality rate was 24% (68 of 284 patients), with a 1·4 times increase in mortality risk for each 10 years of age (p=0·00017), reaching 39% (22 of 57) for patients older than 50 years. Of 284 patients, 81 (28%) had acute kidney injury and 104 (37%) had CNS manifestations and thus both were considered important complications of acute Lassa fever in Nigeria. Acute kidney injury was strongly associated with poor outcome (case-fatality rate of 60% [49 of 81 patients]; odds ratio [OR] 15, p<0·00001). Compared with patients without acute kidney injury, those with acute kidney injury had higher incidence of proteinuria (32 [82%] of 39 patients) and haematuria (29 [76%] of 38

  1. Scarlet fever in Poland in 2014

    Staszewska-Jakubik, Ewa; Czarkowski, Mirosław P; Kondej, Barbara

    Assessment of the epidemiological situation of scarlet fever in Poland in 2014. The evaluation was performed by reviewing surveillance data published in the bulletin “Infectious diseases and poisonings in Poland in 2014” as well as in previous bulletins, and unpublished data collected under Statistical survey program of official statistics. These data relate to cases of scarlet fever registered by health sanitary inspection on the basis of statutory notification of scarlet fever reported by physicians. In 2014, annual, incidence rate of scarlet fever in Poland was about 9% lower in comparison to previous year. There were 22 855 cases all over the country and the incidence was 59.5 per 100,000 population; depending on the voivodeship ranged from 19.5 in podkarpackie to 93.2 in pomorskie. The highest incidence was noted among 4-year-old children (981.4) and 5-year-old children (971.0). However the incidence among children and young people up to 15 years accounted for 95.7% of all cases. The incidence among men (67.2) was higher by 28.5% than incidence among women (52.3). Incidence rate in urban areas, in any size town, was higher than in rural areas. Overall incidence in urban areas was 66.4; in rural areas - 49.0. 1,11% of patients were hospitalized. There were no reported deaths related to scarlet fever. In the surveillance of scarlet fever it is necessary to ensure that the collected data will be valid and reliable. Very low specificity of this surveillance may not only impinge on the assessment of epidemiological situation of this disease in Poland but also overshadow the situation of other diseases, including diseases under elimination program (rubella, measles). This is one of the greatest challenges facing sanitary inspection in the coming years.

    This research investigated effectiveness of temporal artery thermometry (TAT) to detect high rectal fever in children ≥ 91 days and ≤ 4 years old. Rectal temperature was initially evaluated immediately followed by TAT. As expected, the difference between mean rectal (38.05 ± .99 °C) and mean TA (37.55 ± .8 °C) temperatures in subjects (N = 239) was significant (p thermometry with greater frequency at higher temperatures. This observation provides probable explanation for the disparity between these thermometry methods. A TAT sensitivity of 75% and specificity of 85% were determined for detecting high fever (39 °C)-a finding clinically unacceptable. In contrast, among the small number of injured subjects enrolled, TAT detected high rectal fever with 100% sensitivity and specificity. This finding, if confirmed, suggests TAT screening for well and injured children has potential for clinical practice by diminishing rectal measurements and their associated risks in the acute care and/or ambulatory practice setting. © The Author(s) 2014.

    Sandfly fever group viruses in the genus Phlebovirus (family Bunyaviridae) are widely distributed across the globe and are a cause of disease in military troops and indigenous peoples. We assessed the laboratory sensitivity and specificity of the Sand Fly Fever Virus Antigen Assay, a rapid dipstick assay designed to detect sandfly fever Naples virus (SFNV) and Toscana virus (TOSV) against a panel of phleboviruses. The assay detected SFNV and TOSV, as well as other phleboviruses including Aguacate, Anahanga, Arumowot, Chagres, and Punta Toro viruses. It did not detect sandfly fever Sicilian, Heartland, Rio Grande, or Rift Valley fever viruses. It did not produce false positive results in the presence of uninfected sand flies (Lutzomyia longipalpis) or Cache Valley virus, a distantly related bunyavirus. Results from this laboratory evaluation suggest that this assay may be used as a rapid field-deployable assay to detect sand flies infected with TOSV and SFNV, as well as an assortment of other phleboviruses.

    Many papers on the MR features of acute disseminated encephalomyelitis (ADEM) have been published, but only a few described contrast-enhanced MRI for this disease. In this study, we analyzed serial changes in MR features and the contrast-enhancing effect on lesions in five patients (5 men, 4-19 years old) discharged with the final diagnosis of ADEM. Hyperintense lesions in brain/spinal cord were demonstrated on T2-weighted MR images in all cases, but not all lesions were enhanced by Gd-DTPA. In the follow-up study many lesions disappeared, but some lesions were enlarged and some new lesions were found. These findings suggest that, although ADEM is clinically monophasic, some cases may progress with the coexistence of reducing, vanishing, and new lesions. Some clinically acute lesions were not enhanced. This might be explained by the following reasons; lesions on various phases coexist, the damage to the blood-brain barrier in the lesions is of different degrees even if it is on the same phase, and the duration of acute phase activity is short. Additionally, some hyperintense lesions remained for a long time on T2-weighted images in spite of the absence of clinical manifestation. That hyperintense area might reflect edema caused by incomplete repair of the blood-brain barrier. From our evaluation of these five cases, MRI is not useful for the diagnosis and follow-up study of ADEM. (author).

    As the incidence of malaria diminishes, a better understanding of nonmalarial fever is important for effective management of illness in children. In this study, we explored the spectrum of causes of fever in African children. We recruited children younger than 10 years of age with a temperature of 38°C or higher at two outpatient clinics--one rural and one urban--in Tanzania. Medical histories were obtained and clinical examinations conducted by means of systematic procedures. Blood and nasopharyngeal specimens were collected to perform rapid diagnostic tests, serologic tests, culture, and molecular tests for potential pathogens causing acute fever. Final diagnoses were determined with the use of algorithms and a set of prespecified criteria. Analyses of data derived from clinical presentation and from 25,743 laboratory investigations yielded 1232 diagnoses. Of 1005 children (22.6% of whom had multiple diagnoses), 62.2% had an acute respiratory infection; 5.0% of these infections were radiologically confirmed pneumonia. A systemic bacterial, viral, or parasitic infection other than malaria or typhoid fever was found in 13.3% of children, nasopharyngeal viral infection (without respiratory symptoms or signs) in 11.9%, malaria in 10.5%, gastroenteritis in 10.3%, urinary tract infection in 5.9%, typhoid fever in 3.7%, skin or mucosal infection in 1.5%, and meningitis in 0.2%. The cause of fever was undetermined in 3.2% of the children. A total of 70.5% of the children had viral disease, 22.0% had bacterial disease, and 10.9% had parasitic disease. These results provide a description of the numerous causes of fever in African children in two representative settings. Evidence of a viral process was found more commonly than evidence of a bacterial or parasitic process. (Funded by the Swiss National Science Foundation and others.).

    Full Text Available Acute intestinal infections are quite common among children. Their clinical presentations include intoxication syndrome (drowsiness, low appetite, fever etc, infectious toxic syndrome (toxicosis with exicosis, neurotoxicosi, hypovolemic or infectious-toxic shockand diarrhea syndrome. Sometimes intestinal infections can be quite severe and even lethal. However disease duration and outcome depend on timelines and adequacy of prescribed treatment. Main guidelines of intestinal infections treatment include probiotics. That is why the right choice of probiotics is important for a pediatrician. The article contains basic information upon etiopathogenesis, classification, diagnostic criteria and acute pediatric intestinal infections treatment guidelines.Key words: acute intestinal infections, etiopathogenesis, diagnostic criteria, treatment, probiotics, children.

    2000-09-01

    To analyse clinical presentation of rheumatic fever (RF), with special emphasis on cardiac involvement, electrocardiographic and echocardiographic findings and the outcome of the cases referred to Maria Pia Children's Hospital from January 1990 to September 1999. We retrospectively analyzed the clinical files of all cases referred to pediatric cardiology clinics with the suspicion of acute RF (Group 1) or with rheumatic valvular disease and heart failure (Group 2). In group 1 we studied the following: age and sex distribution, year of diagnosis, presence of Jones criteria treatment and outcome. In group 2 we analysed provenance, age of initial onset of RF, age of cardiology referral, treatment and outcome. Thirteen cases were identified, 8 in groups 1 and 5 in group 2. Group 1 included 3 girls and 2 boys, mean age of 10 years. The diagnosis of RF was based in the presence of 2 major and 1 minor manifestation (4/8), 1 major and 2 minor manifestations (1/8) and chorea in 3 cases associated with clinical carditis in one and subclinical carditis in another. Colour Doppler echocardiography showed pathological mitral regurgitation jet in 6 cases, associated with aortic regurgitation in 2 and dilatation of left ventricle in 3. All were treated with penicillin associated with anti-inflammatory drugs in 5 and haloperidol in 3. Group 2 included 3 girls and 2 boys, mean age 9.56 years. Four were from African countries (Angola and Guinea), and one came from the north of Portugal. The elapsed time between the initial acute attack and cardiology referral varied from 5 months to 3 years. All presented severe mitral insufficiency associated with aortic and/or tricuspid valve lesions, and heart failure. All five underwent valve surgery. The secondary prophylaxis was recommended in every patient. There was a recurrence in a child who had interrupted chemoprophylaxis. The patients from African countries were lost for follow-up. RF still remains a problem in present times, with

  9. Milk Fever Control Principles: A Review

    2002-03-01

    Full Text Available Three main preventive principles against milk fever were evaluated in this literature review, and the efficacy of each principle was estimated from the results of controlled investigations. Oral calcium drenching around calving apparently has a mean efficacy of 50%–60% in terms of milk fever prevention as well as prevention of milk fever relapse after intravenous treatment with calcium solutions. However, some drenches have been shown to cause lesions in the forestomacs. When using the DCAD (dietary cation-anion difference principle, feeding rations with a negative DCAD (measured as (Na + K – (Cl + S significantly reduce the milk fever incidence. Calculating the relative risk (RR of developing milk fever from controlled experiments results in a mean RR between 0.19 and 0.35 when rations with a negative versus positive DCAD are compared. The main drawback from the DCAD principle is a palatability problem. The principle of feeding rations low in calcium is highly efficient in milk fever prevention provided the calcium intake in the dry period is kept below 20 g per day. Calculating the relative risk (RR of developing milk fever from controlled experiments results in a very low mean RR (between 0 and 0.20 (daily calcium intake below versus above 20 g/d. The main problem in implementing the low-Ca principle is difficulties in formulating rations sufficiently low in calcium when using commonly available feeds. The use of large doses of vitamin D metabolites and analogues for milk fever prevention is controversial. Due to toxicity problems and an almost total lack of recent studies on the subject this principle is not described in detail. A few management related issues were discussed briefly, and the following conclusions were made: It is important to supply the periparturient cow with sufficient magnesium to fulfil its needs, and to prevent the dry cows from being too fat.

    Yellow fever (YF) is a mosquito-borne viral hemorrhagic fever, which is a serious and potentially fatal disease with no specific antiviral treatment that can be effectively prevented by an attenuated vaccine (YEL). Despite the long history of safe and efficacious YF vaccination, sporadic case reports of serious adverse events (SAEs) have been reported, including yellow fever vaccine-associated neurotropic disease (YEL-AND). YEL-AND usually appears within one month of YF vaccination, manifesting as meningoencephalitis, Guillain-Barré syndrome (GBS) or acute disseminated encephalomyelitis (ADEM). We report a case of YEL-AND with meningitis presentation in a 39-year-old Caucasian man without evidence of significant risk factors, which was confirmed by the presence of the YF virus and specific immunoglobulin G (IgG) antibodies in the cerebrospinal fluid (CSF). In conclusion, we should stress the importance of balancing the risk of SAEs associated with the vaccine and the benefits of YF vaccination for each patient individually.

    Full Text Available Dengue fever is gaining importance in Singapore with an increase in the number of cases and mortality in recent years. Although prolonged and saddleback fever have been reported in dengue fever, there are no specific studies on their significance in dengue. This study aims to examine the prevalence of prolonged and saddleback fever in dengue as well as their associations with dengue severity. A total of 2843 polymerase-chain reaction (PCR confirmed dengue patients admitted to Tan Tock Seng Hospital from 2004 to 2008 were included in the study.

    Acute septicemic spirochetosis was diagnosed in an adult male northern spotted owl (Strix occidentalis caurina) found dead in Kittitas County, Washington, USA. Gross necropsy findings included marked enlargement of the liver and spleen and serofibrinous deposits on the serous membranes lining the body cavities and the pericardial and perihepatic sacs. Microscopic observations included macrophage infiltration in the liver and spleen with mild thrombosis and multifocal necrosis, as well as hemorrhage and acute inflammation in the choroid plexus of the brain. No viruses or pathogenic bacteria were isolated from brain, liver, or spleen, and no parasites were found in blood smears or impression smears of the liver. Chlamydial culture attempts were unsuccessful and no chlamydial antibodies were detected in serum. In silver-stained microscopic sections and by transmission electron microscopy of liver, numerous long, thin, spiral-shaped bacteria were seen in the liver, spleen, cerebral ventricles, and within blood vessels in many organs. The organism was identified as a member of the Borrelia genus by sequence analysis of the PCR-amplified 16S rRNA gene. The most closely related species is B. hermsii, an agent of relapsing fever in humans in the western United States. This is the first report of a relapsing fever-related Borrelia in a wild bird.

    DENV infection can induce different clinical manifestations varying from mild forms to dengue fever (DF) or the severe hemorrhagic fever (DHF). Several factors are involved in the progression from DF to DHF. No marker is available to predict this progression. Such biomarker could allow a suitable medical care at the beginning of the infection, improving patient prognosis. The aim of this study was to compare the serum expression levels of acute phase proteins in a well-established cohort of dengue fever (DF) and dengue hemorrhagic fever (DHF) patients, in order to individuate a prognostic marker of diseases severity. The serum levels of 36 cytokines, chemokines and acute phase proteins were determined in DF and DHF patients and compared to healthy volunteers using a multiplex protein array and near-infrared (NIR) fluorescence detection. Serum levels of IL-1ra, IL-23, MIF, sCD40 ligand, IP-10 and GRO-α were also determined by ELISA. At the early stages of infection, GRO-α and IP-10 expression levels were different in DF compared to DHF patients. Besides, GRO-α was positively correlated with platelet counts and IP-10 was negatively correlated with total protein levels. These findings suggest that high levels of GRO-α during acute DENV infection may be associated with a good prognosis, while high levels of IP-10 may be a warning sign of infection severity.

    Full Text Available Bioelectrical impedance analysis (BIA is a widely used technique to assess body composition and nutritional status. While bioelectrical values are affected by diverse variables, there has been little research on validation of BIA in acute illness, especially to understand prognostic significance. Here we report the use of BIA in acute febrile states induced by influenza.Bioimpedance studies were conducted during an H1N1 influenza A outbreak in Venezuelan Amerindian villages from the Amazonas. Measurements were performed on 52 subjects between 1 and 40 years of age, and 7 children were re-examined after starting Oseltamivir treatment. Bioelectrical Impedance Vector Analysis (BIVA and permutation tests were applied.For the entire sample, febrile individuals showed a tendency toward greater reactance (p=0.058 and phase angle (p=0.037 than afebrile individuals, while resistance and impedance were similar in the two groups. Individuals with repeated measurements showed significant differences in bioimpedance values associated with fever, including increased reactance (p<0.001 and phase angle (p=0.007, and decreased resistance (p=0.007 and impedance (p<0.001.There are bioelectrical variations induced by influenza that can be related to dehydration, with lower extracellular to intracellular water ratio in febrile individuals, or a direct thermal effect. Caution is recommended when interpreting bioimpedance results in febrile states.

    2014-12-01

    OBJECTIVE To assess the validity of dengue fever reports and how they relate to the definition of case and severity. METHODS Diagnostic test assessment was conducted using cross-sectional sampling from a universe of 13,873 patients treated during the fifth epidemiological period in health institutions from 11 Colombian departments in 2013. The test under analyses was the reporting to the National Public Health Surveillance System, and the reference standard was the review of histories identified by active institutional search. We reviewed all histories of patients diagnosed with dengue fever, as well as a random sample of patients with febrile syndromes. The specificity and sensitivity of reports were estimated for this purpose, considering the inverse of the probability of being selected for weighting. The concordance between reporting and the findings of the active institutional search was calculated using Kappa statistics. RESULTS We included 4,359 febrile patients, and 31.7% were classified as compatible with dengue fever (17 with severe dengue fever; 461 with dengue fever and warning signs; 904 with dengue fever and no warning signs). The global sensitivity of reports was 13.2% (95%CI 10.9;15.4) and specificity was 98.4% (95%CI 97.9;98.9). Sensitivity varied according to severity: 12.1% (95%CI 9.3;14.8) for patients presenting dengue fever with no warning signs; 14.5% (95%CI 10.6;18.4) for those presenting dengue fever with warning signs, and 40.0% (95%CI 9.6;70.4) for those with severe dengue fever. Concordance between reporting and the findings of the active institutional search resulted in a Kappa of 10.1%. CONCLUSIONS Low concordance was observed between reporting and the review of clinical histories, which was associated with the low reporting of dengue fever compatible cases, especially milder cases.

    2015-12-04

    Dengue fever is endemic in developing nations worldwide with as many as 500,000 annual cases of dengue hemorrhagic fever (DHF) and dengue shock syndrome (DSS). A prompt and accurate diagnosis early in the disease course is essential for prompt identification and treatment of severe complications of the dengue virus infection (DVI). We identified cross-reactivity of a rapid IgM test for typhoid fever in patients with febrile illnesses that were determined to be due to dengue virus. All patients with documented DVI during a recent epidemic in Pakistan also underwent diagnostic testing for Salmonella enterica serovar Typhi. The diagnosis of DVI was made based on clinical findings and the positive results for dengue non-structural protein 1 antigen (NS1Ag) and/or dengue IgM antibody (anti-D IgM) during the acute phase of febrile illness. Patients with positive test results for Salmonella typhi (S. Typhi) IgM also had their blood cultures done. In the group of 322 patients with clinical and serological evidence of DVI, 107 also tested positive for S. Typhi IgM. Blood cultures were negative for S. Typhi bacteria in all patients. Principal disease features included fever, headache, myalgia, retro-orbital pain, and a rash accompanied by thrombocytopenia and leukopenia. Comparisons of clinical and routine laboratory findings between the S. Typhi-positive and negative groups showed no significant differences. Patients testing positive for both NS1Ag and anti-D IgM were significantly more likely to test positive for S. Typhi IgM, even in the absence of typhoid fever. No routine antibiotics were used and all patients survived. One-third of a large group of patients with primary DVI also demonstrated false positive results for typhoid fever. Cross-reactivity of a rapid immunoassay for typhoid fever has not been previously reported in DVI or any other flavivirus infections. Until these findings can be further evaluated, clinicians should be cautious in

    To describe the clinical and laboratory features of benign acute childhood myositis. 40 children of BACM were seen during October 2001 to February 2002, 22 (52%) were male with mean age of 5.3 years. Duration of illness was 3.97 days. Preceding symptoms included fever, leg pain, vomiting and inability to walk. A provisional diagnosis of viral myositis was made in 26 (66%). Guillian Barre Syndrome was the most common referral diagnosis. 11 (27.5%) children had leucopenia with lymphocytic response and 16 (40%) had thrombocytopenia. CRP was negative in 32 (80%). CPK was markedly elevated (more than 1000 IU/l) in 18 (45%) and more than 500 IU/l in 11 (27.5%) remaining between 200 to 500 IU/l. Associated features were hepatitis (elevated SGOT & SGPT) in 28 (70%) and shock in 5 (12.5%). Serological test were indicative of dengue virus (Elisa PAN BIO) in 20 (50%) of which 8 (25%) were primary dengue and 12 (30%) were secondary dengue. The outcome of therapy mainly supportive were excellent. Benign acute myositis occurs often in association with viral infection. In the present study, Dengue virus was positive in 20 (50%) children. Benign acute myositis can be differentiated from more serious causes of walking difficulty by presence of calf and thigh muscle tenderness on stretching, normal power and deep tendon reflex and elevated CPK.

    This study was undertaken to analyze the characteristics of fever after cancer chemotherapy in order to reduce unnecessary medical care. Retrospectively, 1016 consecutive cycles of cancer chemotherapy were analyzed. Fever was defined as a temperature of ≥ 37.5 °C lasting for 1 h. Age, sex, tumor histology, the treatment regimen, the timing of fever onset, the number of days for which the fever persisted, the cause of the fever, the presence or absence of radiotherapy, and the use of granulocyte colony-stimulating factor (G-CSF) were examined. The patients included 748 males and 268 females (median age = 68, range = 29-88), of whom 949, 52, and 15 were suffering from lung cancer, malignant pleural mesothelioma, and other diseases, respectively. Fever was observed in 367 cycles (36 %), including 280 cycles (37 %) involving males and 87 cycles (32 %) involving females. Fever occurred most commonly in the first cycles and was higher than later cycles (41 vs. 30 %, p Fever occurred most frequently on posttreatment days 4 (8 %), 3 (7 %), and 12 (7 %), and the distribution of fever episodes exhibited two peaks on posttreatment days 3 and 4 and 10-14. Fever on posttreatment days 3 and 4 was most commonly observed in patients treated with gemcitabine (20 %) or docetaxel (18 %). The causes of fever included infection (47 %; including febrile neutropenia [24 %]), adverse drug effects (24 %), unknown causes (19 %), and tumors (7 %). Radiotherapy led to a significant increase in the frequency of fever (46 vs. 34 %, p fever in patients who received G-CSF were higher than those who did not receive G-CSF (44 vs. 31 %, p fever and avoid unnecessary examination and treatments including prescribing antibiotics.

    Dengue fever and dengue hemorrhagic fever are re-emerging diseases that are endemic in the Tropics. The global prevalence of dengue cases has increased in South-East Asia, Africa, the Western Pacific, and the Americas. The increasingly widespread distribution and the rising incidence of dengue virus infections are related to increased distribution of Aedes aegypti, an increasingly urban population, and increasing air travel. Several Southeast Asian countries show that the age of the reported dengue cases has increased from 5-9 years, to older children and young adults. Dengue infection in adolescents and adults has also been recognized as a potential hazard to international travelers returning from endemic areas, especially SoutheastAsia. Dengue is one disease entity with different clinical presentations; often with unpredictable clinical evolutions and outcomes. Bleeding manifestations in adult patients, including petechiae and menorrhagia were also frequently found; however, massive hematemesis may occur in adult patients because of peptic ulcer disease and may not be associated with profound shock as previously reported in children. Although shock and plasma leakage seem to be more prevalent as age decreases, the frequency of internal hemorrhage rises as age increases. Increase in liver enzymes found in both children and adults indicated liver involvement during dengue infections. Pre-existing liver diseases in adults such as chronic hepatitis, alcoholic cirrhosis, and hemoglobinopathies may aggravate the liver impairment in dengue infection. Fulminant hepatitis is a rare but well described problem in adult patients with dengue infection. Currently, no specific therapeutic agent exists for dengue. The early recognition of dengue infection, bleeding tendency, and signs of circulatory collapse would reduce mortality rates in adult patients with dengue infection.

    Full Text Available Viral etiologies of fever, including dengue, Chikungunya, influenza, rota and adeno viruses, cause major disease burden in tropical and subtropical countries. The lack of diagnostic facilities in developing countries leads to failure to estimate the true burden of such illnesses, and generally the diseases are underreported. These diseases may have similar symptoms with other causes of acute febrile illnesses including malaria and hence clinical diagnosis without laboratory tests can be difficult. This study aimed to identify viral etiologies as a cause of fever in children and their co-infections with malaria.A cross sectional study was conducted for 6 months at Kilosa district hospital, Tanzania. The participants were febrile children aged 2-13 years presented at the outpatient department. Diagnostic tests such as IgM and IgG ELISA, and PCR were used.A total of 364 patients were enrolled, of these 83(22.8% had malaria parasites, 76 (20.9% had presumptive acute dengue infection and among those, 29(38.2% were confirmed cases. Dengue was more likely to occur in children ≥ 5 years than in <5 years (OR 2.28, 95% CI: 1.35-3.86. Presumptive acute Chikungunya infection was identified in 17(4.7% of patients. We observed no presenting symptoms that distinguished patients with Chikungunya infection from those with dengue infection or malaria. Co-infections between malaria and Chikungunya, malaria and dengue fever as well as Chikungunya and dengue were detected. Most patients with Chikungunya and dengue infections were treated with antibacterials. Furthermore, our results revealed that 5(5.2% of patients had influenza virus while 5(12.8% had rotavirus and 2(5.1% had adenovirus.Our results suggest that even though viral diseases are a major public health concern, they are not given due recognition as a cause of fever in febrile patients. Emphasis on laboratory diagnostic tests for proper diagnosis and management of febrile patients is recommended.

    Full Text Available A febre amarela é doenca infecciosa não-contagiosa causada por um arbovírus mantido em ciclos silvestres em que macacos atuam como hospedeiros amplificadores e mosquitos dos gêneros Aedes na África, e Haemagogus e Sabethes na América, são os transmissores. Cerca de 90% dos casos da doença apresentam-se com formas clínicas benignas que evoluem para a cura, enquanto 10% desenvolvem quadros dramáticos com mortalidade em torno de 50%. O problema mostra-se mais grave em África onde ainda há casos urbanos. Nas Américas, no período de 1970-2001, descreveram-se 4.543 casos. Os países que mais diagnosticaram a doença foram o Peru (51,5%, a Bolívia (20,1% e o Brasil (18,7%. Os métodos diagnósticos utilizados incluem a sorologia (IgM, isolamento viral, imunohistoquímica e RT-PCR. A zoonose não pode ser erradicada, mas, a doença humana é prevenível mediante a vacinação com a amostra 17D do vírus amarílico. A OMS recomenda nova vacinação a cada 10 anos.

    2004-03-01

    Alexander the Great had a profound effect on world history. His conquests covered the entire known world at the time, and he was responsible for the spread of Greek culture throughout the ancient world. In Babylon in 323 BC, Alexander died when he was nearly 33 years old. Possible explanations for his death have included alcoholic liver disease and strychnine poisoning, but little data support either condition as the cause of his death. Alexander most likely died from malaria or typhoid fever, which were rampant in ancient Babylon. The description of his final illness from the royal diaries is consistent with typhoid fever or malaria but is most characteristic of typhoid fever.

  14. Incidental histological diagnosis of acute rheumatic carditis: case report and review of the literature.

    Guilherme S. Spina

    2014-11-01

    Full Text Available Rheumatic fever remains endemic in many countries and frequently causes heart failure due to severe chronic rheumatic valvular heart disease, which requires surgical treatment. Here, we report on a patient who underwent an elective surgical correction for mitral and aortic valvular heart disease and had a post-operative diagnosis of acute rheumatic carditis. The incidental finding of Aschoff bodies in myocardial biopsies is frequently reported in the nineteenth-century literature, with prevalences as high as 35%, but no clinical or prognostic data on the patients is included. The high frequency of this finding after cardiac surgery in classical reports suggests that these patients were not using secondary prophylaxis for rheumatic fever. We discuss the clinical diagnosis of acute rheumatic myocarditis in asymptomatic patients and the laboratorial and imaging methods for the diagnosis of acute rheumatic carditis. We also discuss the prognostic implications of this finding and review the related literature.

  15. Paracetamol in fever in critically ill patients-an update.

    Science.gov (United States)

    Chiumello, D; Gotti, M; Vergani, G

    2017-04-01

    Fever, which is arbitrary defined as an increase in body temperature above 38.3°C, can affect up to 90% of patients admitted in intensive care unit. Induction of fever is mediated by the release of pyrogenic cytokines (tumor necrosis factor α, interleukin 1, interleukin 6, and interferons). Fever is associated with increased length of stay in intensive care unit and with a worse outcome in some subgroups of patients (mainly neurocritically ill patients). Although fever can increase oxygen consumption in unstable patients, on the contrary, it can activate physiologic systems that are involved in pathogens clearance. Treatments to reduce fever include the use of antipyretics. Thus, the reduction of fever might reduce the ability to develop an efficient host response. This balance, between harms and benefits, has to be taken into account every time we decide to treat or not to treat fever in a given patient. Among the antipyretics, paracetamol is one of the most common used. Paracetamol is a synthetic, nonopioid, centrally acting analgesic, and antipyretic drug. Its antipyretic effect occurs because it inhibits cyclooxygenase-3 and the prostaglandin synthesis, within the central nervous system, resetting the hypothalamic heat-regulation center. In this clinical review, we will summarize the use of paracetamol as antipyretic in critically ill patients (sepsis, trauma, neurological, and medical). Copyright © 2016 Elsevier Inc.

    Chikungunya fever occurred in an epidemic form in the state of Maharashtra after a gap of about 32 years. Many cases with symptoms which were suggestive of Chikungunya fever were reported from the village Kasegaon, Dist Sangli, Maharashtra, India. Hence, this study was done to assess the magnitude of the outbreak and to identify the possible socio-environmental factors which are responsible for Chikungunya fever. This cross sectional study was carried out at Kasegaon by a team from the Krishna Institute of Medical Sciences, Karad, Maharashtra, in collaboration with the Primary Health Centre, Kasegaon, Distt. Sangli. The Chikungunya prevalence was 9.6%. There were 154 clinically suspected Chikungunya fever cases. Of these, 54.5% were males and 45.5% were females. About 72.7% of the cases were in the age range of 11-50 years, which is the active age group. The main symptoms were an acute onset of fever with joint pain (100%). Multiple joints were involved in (89.6%) cases. The mean duration of the fever was 3 days (range 1-10 days). About 40.3% people preferred to consult a government health facility. In the affected area, 83.1% people were aware of Chikungunya fever. Only few (1.1%) knew the vectors which were responsible for the Chikungunya transmission. Among the people in the affected area, 33.1% had knowledge on insecticide spraying, 23.2% had knowledge on the use of mosquito nets and repellents, 12.5% had knowledge on source reduction and 0.8% had knowledge on larvicides.

    To prevent relapse, high risk paediatric acute lymphoblastic leukaemia (ALL) is treated very intensively. However, most patients who eventually relapse have standard or medium risk ALL with low minimal residual disease (MRD) levels. We analysed recurrent microdeletions and other clinical prognostic factors in a cohort of 475 uniformly treated non-high risk precursor B-cell ALL patients with the aim of better predicting relapse and refining risk stratification. Lower relapse-free survival at 7 years (RFS) was associated with IKZF1 intragenic deletions (P 5 × 10 -5 (P < 0·0001) and High National Cancer Institute (NCI) risk (P < 0·0001). We created a predictive model based on a risk score (RS) for deletions, MRD and NCI risk, extending from an RS of 0 (RS0) for patients with no unfavourable factors to RS2 +  for patients with 2 or 3 high risk factors. RS0, RS1, and RS2 +  groups had RFS of 93%, 78% and 49%, respectively, and overall survival (OS) of 99%, 91% and 71%. The RS provided greater discrimination than MRD-based risk stratification into standard (89% RFS, 96% OS) and medium risk groups (79% RFS, 91% OS). We conclude that this RS may enable better early therapeutic stratification and thus improve cure rates for childhood ALL. © 2017 John Wiley & Sons Ltd.

    Dengue hemorrhagic fever is caused by dengue virus infection. The classical manifestations consist of fever, thrombocytopenia, and hemoconcentration. However, its unusual complications may be fatal, such as prolong shock, massive bleeding, volume overload, and unusual manifestations, for example, severe rhabdomyolysis. Here we report a case of 17-year old Thai man who was referred to our hospital because of 7-day fever with thrombocytopenia, hemoconcentration and right pleural effusion. The serology tests confirmed to be dengue infection. He developed various complications: severe hepatitis, coagulopathy, and heavy proteinuria; encephalopathy that needed a respiratory ventilator. On day 12 of fever, he had myalgia and passed dark urine. Serum creatinine and serum creatinine phosphokinase (CPK) were found abnormally high. He was diagnosed as severe rhabdomyolysis with acute kidney injury, and immediate hemodialysis was performed. He did not respond to treatment and expired within three hours. Although the mechanism of severe rhabdomyolysis in dengue fever is not clearly known, it may theoretically be proposed such as direct muscle cell injury leading to myositis by dengue virus, myotoxic cytokines which are produced in response to viral infection, dehydration or hypophosphatemia.

    Intentional self-poisonings with seeds from the yellow oleander tree (Thevetia peruviana) are widely reported. Activated charcoal has been suggested to benefit patients with yellow oleander poisoning by reducing absorption and/or facilitating elimination. Two recent randomized controlled trials (RCTs) assessing the efficacy of activated charcoal yielded conflicting outcomes in terms of mortality. The effect of activated charcoal on the pharmacokinetics of Thevetia cardenolides has not been assessed. This information may be useful for determining whether further studies are necessary. Serial blood samples were obtained from patients enrolled in an RCT assessing the relative efficacy of single-dose and multiple-dose activated charcoal (SDAC and MDAC, respectively) compared with no activated charcoal (NoAC). The concentration of Thevetia cardenolides was estimated with a digoxin immunoassay. The effect of activated charcoal on cardenolide pharmacokinetics was compared between treatment groups by determining the area under the curve for each patient in the 24 hours following admission, the 24-hour mean residence time, and regression lines obtained from serial concentration points, adjusted for exposure. Erratic and prolonged absorption patterns were noted in each patient group. The apparent terminal half-life was highly variable, with a median time of 42.9 hours. There was a reduction in 24-hour mean residence time and in the apparent terminal half-life estimated from linear regression in patients administered activated charcoal, versus the control group (NoAC). This effect was approximately equal in patients administered MDAC or SDAC. Activated charcoal appears to favorably influence the pharmacokinetic profile of Thevetia cardenolides in patients with acute self-poisoning and may have clinical benefits. Given the conflicting clinical outcomes noted in previous RCTs, these mechanistic data support the need for further studies to determine whether a particular subgroup

    Although body temperature is one of four key vital signs routinely monitored and treated in clinical practice, relatively little is known about the symptoms associated with febrile states. The purpose of this study was to assess the validity, reliability and feasibility of the Fever Assessment Tool (FAST) in an acute care research setting. Qualitative: To assess content validity and finalize the FAST instrument, 12 adults from an inpatient medical-surgical unit at the National Institutes of Health (NIH) Clinical Center participated in cognitive interviews within approximately 12 h of a febrile state (tympanic temperature ≥ 38° Celsius). Quantitative: To test reliability, validity and feasibility, 56 new adult inpatients completed the 21-item FAST. The cognitive interviews clarified and validated the content of the final 21-item FAST. Fifty-six patients completed the FAST from two to 133 times during routine vital sign assessment, yielding 1,699 temperature time points. Thirty-four percent of the patients (N = 19) experienced fever at one or more time points, with a total of 125 febrile time points. Kuder-Richardson 20 (KR-20) reliability of the FAST was 0.70. Four nonspecific symptom categories, Tired or Run-Down (12), Sleepy (13), Weak or Lacking Energy (11), and Thirsty (9) were among the most frequently reported symptoms in all participants. Using Generalized Estimating Equations (GEE), the odds of reporting eight symptoms, Warm (4), Sweating (5), Thirsty (9), General Body Aches (10), Weak or Lacking Energy (11), Tired or Run Down (12) and Difficulty Breathing (17), were increased when patients had a fever (Fever Now), compared to the two other subgroups-patients who had a fever, but not at that particular time point, (Fever Not Now) and patients who never had a fever (Fever Never). Many, but not all, of the comparisons were significant in both groups. Results suggest the FAST is reliable, valid and easy to administer. In addition to symptoms usually

    Dengue fever is a common mosquito-borne viral illness with a clinical spectrum ranging from a simple febrile illness to potentially life-threatening complications such as dengue hemorrhagic fever and dengue shock syndrome. Dengue infection can affect many organs, including the central nervous system. The neurological manifestations reported in dengue infections are meningitis, encephalitis, stroke, acute disseminated encephalomyelitis, and Guillain-Barré syndrome. We report the cases of two interesting patients with confirmed dengue infection who presented with complications of possible central nervous system vasculitis and cranial nerve palsy. The first patient was a 53-year-old previously healthy Singhalese woman who developed acute-onset slurring of speech and ataxia with altered sensorium 1 day after recovery from a critical period of dengue hemorrhagic fever. Subsequent investigations revealed evidence of encephalopathy with brainstem ischemic infarctions. Her clinical picture was compatible with central nervous system vasculitis. She was treated successfully with intravenous steroids and had a full functional recovery. The second patient was a middle-aged Singhalese woman who had otherwise uncomplicated dengue infection. She developed binocular diplopia on day 4 of fever. An ocular examination revealed a convergent squint in the left eye with lateral rectus palsy but no other neurological manifestation. Central nervous system vasculitis due to dengue infection is a very rare phenomenon, and to the best of our knowledge, only one case of central nervous system vasculitis has been reported to date, in a patient of pediatric age. Cranial nerve palsy related to dengue infection is also rare, and only a few cases of isolated abducens nerve palsy have been reported to date. The two cases described in this report illustrate the rare but important central nervous system manifestations of dengue fever and support the fact that the central nervous system is one of the

    The objective of this study is to present epidemiological characteristics and clinical symptoms of dengue fever cases in Czech workers who acquired the infection while working on the island of Fushivelavaru, Maldives. Furthermore, the study compares the sensitivity of novel direct detection assays, i.e. Real-Time Polymerase Chain Reaction (RT-PCR) and detection of Dengue NS1 antigen. The retrospective study evaluated the clinical course of dengue fever cases in Czech workers returning from a job in the Maldives who were diagnosed with dengue virus infection from September 1 to October 31, 2012. The laboratory diagnosis of dengue fever was based on the serological detection of IgM and IgG antibodies, detection of dengue NS1 antigen by enzyme-linked immunosobent assay (ELISA), and detection of dengue virus DNA by RT-PCR. The infection with dengue virus was confirmed in 18 males with a median age of 40 years (IQR 36-47) who returned from a job in the Maldives. Only one patient required admission to the hospital while the others were treated on an outpatient basis. The most frequently observed symptoms were fever (18), headache (9), muscle and joint pain (8 and 7, respectively), and rash (9). Typical laboratory findings were leukocytopenia and thrombocytopenia, a low CRP level, and elevated aminotransferase activity. The clinical course was uncomplicated in all patients. The dengue NS1 antigen detection (positive in all 10 patients with acute dengue fever) showed significantly higher sensitivity than the detection of viral RNA using RT-PCR (positive in 4 patients), p = 0.011. Although the vast majority of dengue fever cases are diagnosed among travellers returning from the tropics, the presented study points out the risks posed by dengue fever to long-term workers in endemic areas. The infection in the serologically naïve hosts is usually uncomplicated; however, infected persons are at significant risk of developing a severe complicated clinical course if challenged

    To study the clinical profile and outcome of the atypical manifestations of dengue fever in children. All children (0-12 y of age) diagnosed and confirmed as dengue fever at a tertiary care hospital at Puducherry, between the 1st of August 2012 and January 31st 2015 were reviewed retrospectively from hospital case records as per the revised World Health Organization (WHO) guidelines 2011 for dengue fever. The diagnosis was confirmed by NS1 antigen-based ELISA test or dengue serology for IgM and IgG antibodies and the data was analyzed using SPSS 16.0 statistical software. Out of 254 children admitted with dengue fever, non-severe dengue and severe dengue were seen in 62.6 % and 37.4 % respectively. Atypical manifestations were seen in 106 cases (41.7 %). Mean age of presentation was 6.9(3.3) y. M: F ratio was 1.2:1. The common manifestations of severe dengue infection were shock (37.4 %), bleeding (20.1 %) and multi-organ dysfunction (2.4 %). The most common atypical manifestations of dengue fever were lymphadenopathy (41.7 %), splenomegaly (21.2 %), biphasic fever (18.1 %), hepatitis (11.4 %), febrile diarrhea (6.3 %), refractory shock (2.4 %) and impaired consciousness (1.9 %). The other atypical manifestations present were portal hypertension, acalculous cholecystitis, appendicitis, acute respiratory distress syndrome (ARDS), myocarditis, pericardial effusion, paroxysmal supraventricular tachycardia (PSVT), myositis, acute kidney injury (AKI), hemophagocytic syndrome and disseminated intravascular coagulopathy (DIC). Platelet count did not always correlate well with the severity of bleeding. There were six deaths (2.4 %) and out of them four presented with impaired consciousness (66.6 %). The common causes for poor outcome were multiorgan failure, encephalopathy and refractory shock. The atypical manifestations of dengue fever are no more a rare entity. Clinicians should have a high index of suspicion and vigilance for atypical manifestations of

    Chikungunya fever is a tropical vector-borne disease that has been spreading rapidly around the world during the last 10 years, and which has been usually misdiagnosed as dengue. Nowadays, this disease is increasing in Mexico, mainly in the southern and central zones of the country, being significantly more common in women, children and young adults (28% in<20 years of age). The classical presentation includes fever, arthralgia, polyarthritis, back-pain, and skin rashes. Although symptoms and treatment are similar to those for dengue, there are key clinical features to differentiate these two diseases. Copyright © 2016 Hospital Infantil de México Federico Gómez.

    MRC Symposium (1977).Thorax, 32, 653-663. Humidifier fever. In enclosed environments, it may be necessary to regulate temperature, ventilation, and humidity to maintain comfortable working conditions. Several systems can be used although in terms of installation and running costs a simple radiator system is far more economical than air conditioning with complete temperature and humidity control. Humidity control requires the introduction of water into a moving current of air, and in such a system baffle plates are often used to eliminate large droplets; also any unused water is usually recirculated. Organic dust drawn into the system and settling on the baffle plates and in the mixing chamber may be utilised by micro-organisms introduced from the atmosphere and from the water supply, and a biomass builds up. Microbial material is then voided into the working atmosphere by the ventilation system. Under appropriate exposure conditions susceptible individuals may succumb to an episode of humidifier fever, an influenza-like illness with pyrexia and malaise as the main symptoms, but cough, chest tightness, dyspnoea and weight loss may also be seen. The episodes usually occur after absence from work for a few days and have been termed `Monday sickness'. Individuals are often able to return to work the next day and appear refractory to further exposure. The disease is of the winter months probably due to the larger amount (up to 90%) of fresh air drawn into the humidifier during the summer. In the blood of exposed subjects precipitins are usually present to extracts of baffle plate material and recirculating water although they are not necessarily indicative of disease. Skin tests may be positive and inhalation challenge has reproduced the disease in susceptible individuals. Many organisms may be isolated from baffle plates and recirculating water but only amoeba extracts have produced consistently positive reactions with sera from affected individuals. Remedial actions

    Typhoid and paratyphoid are febrile illnesses, due to a bacterial infection, which remain common in many low- and middle-income countries. The World Health Organization (WHO) currently recommends the fluoroquinolone antibiotics in areas with known resistance to the older first-line antibiotics. To evaluate fluoroquinolone antibiotics for treating children and adults with enteric fever. We searched The Cochrane Infectious Disease Group Specialized Register (February 2011); Cochrane Central Register of Controlled Trials (CENTRAL), published in The Cochrane Library (2011, Issue 2); MEDLINE (1966 to February 2011); EMBASE (1974 to February 2011); and LILACS (1982 to February 2011). We also searched the metaRegister of Controlled Trials (mRCT) in February 2011. Randomized controlled trials examining fluoroquinolone antibiotics, in people with blood, stool or bone marrow culture-confirmed enteric fever. Two authors independently assessed the trial's methodological quality and extracted data. We calculated risk ratios (RR) for dichotomous data and mean difference for continuous data with 95% confidence intervals (CI).Comparative effectiveness has been interpreted in the context of; length of treatment, dose, year of study, known levels of antibiotic resistance, or proxy measures of resistance such as the failure rate in the comparator arm. Twenty-six studies, involving 3033 patients, are included in this review.Fluoroquinolones versus older antibiotics (chloramphenicol, co-trimoxazole, amoxicillin and ampicillin)In one study from Pakistan in 2003-04, high clinical failure rates were seen with both chloramphenicol and co-trimoxazole, although resistance was not confirmed microbiologically. A seven-day course of either ciprofloxacin or ofloxacin were found to be superior. Older studies of these comparisons failed to show a difference (six trials, 361 participants).In small studies conducted almost two decades ago, the fluoroquinolones were demonstrated to have fewer

    Self-reported symptoms including urinary, bowel and sexual side effects were investigated prospectively at multiple assessment points before and after combined radiotherapy of prostate cancer including HDR brachytherapy and neoadjuvant androgen deprivation therapy. Between April 2000 and June 2003, patients with predominantly advanced localized prostate tumours subjected to this treatment were asked before treatment and on follow-up visits to complete a questionnaire covering urinary, bowel and sexual problems. The mainly descriptive analyses included 525 patients, responding to at least one questionnaire before or during the period 2-34 months after radiotherapy. Adding androgen deprivation before radiotherapy significantly worsened sexual function. During radiotherapy, urinary, bowel and sexual problems increased and were reported at higher levels up to 34 months, although there seemed to be a general tendency to less pronounced irritative bowel and urinary tract symptoms over time. No side effects requiring surgery were reported. Classic late irradiation effects such as mucosal bleeding were demonstrated mainly during the second year after therapy, but appear less pronounced in comparison with dose escalated EBRT series. In conclusion, despite the high radiation dose given, the toxicity seemed comparable with that of other series but long term (5-10 years) symptom outcome has to be determined

    We describe a case of Guillain-Barre syndrome (GBS) associated with hemorrhagic fever with renal syndrome. To our knowledge, only five cases of GBS associated with Hantavirus infection have been reported so far. A 62-year-old man presented intermittent fever, chill and oliguria. According to remarkable leukocytosis, atypical lymphocytes, thrombocytopenia and former dwelling in hemorrhagic fever-endemic area, he was suspected as hemorrhagic fever with renal syndromeand certified with positive Hantavirus IgG. Later, the patient had symmetrical flaccid paralysis of all extremities. Electromyography showed peripheral nerve injury (mainly in axon). The patient was diagnosed as having acute motor sensory axonal neuropathy (AMSAN). After immunoglobulin infusion, patient showed progressive recovery and was transferred 3 weeks after his first admission to a rehabilitation center. Our case was the 6th reported case of GBS associated with hemorrhagic fever with renal syndrome. Moreover, we for the first time classified the subtype of GBS (AMSAN) based on the electrophysiology characteristics. GBS should be suspected in patients who are already diagnosed as hemorrhagic fever with renal syndrome when delayed symmetrical limb paralysis occurs. Until recent now, GBS was only reported in hemorrhagic fever patients in Europe and Asia, which termed as hemorrhagic fever with renal syndrome.

    To investigate the clinical characteristics of the inpatients suffering from dengue fever in order to provide references for better diagnosis and treatment. The clinical data of 158 dengue fever patients admitted to the First Affiliated Hospital of Sun Yat-Sen University from July 23rd to October 31st, 2014 during the 2014 epidemic in Guangzhou area were retrospectively analyzed, including general clinical manifestations, conventional examinations, pathogenesis, and prognosis. The mean age of the 158 patients was ( 56 ± 20 ) years, with half of them over 60 years old (79 cases). Among them, 94 (59.49%) were male. (1) The common manifestations included fever (100%), headache (70.89%), myalgia/bone soreness (62.03%), and skin rash (54.43%). Bleeding and plasma leakage were found in 25.95% and 14.56% of the patients respectively. (2) Laboratory examination: leucopenia (75.32%) and thrombocytopenia (77.85%) were found, and alanine aminotransferase (ALT) and aspartate aminotransferase ( AST ) were elevated in 57.59% and 77.85% of the patients respectively. However, elevation of blood hematocrit was rare (1.27% ). (3) It was found that in the acute phase (0 - 5 days of the onset), serum dengue virus antibody IgM (DF-IgM) was positive in 63.54% of the patients (61/96), and 92.62% (113/122) of patients were dengue virus RNA ( DENA-RNA ) positive. (4) The rate of comorbidity in this study was 55.06% ( 87/158 ), including hypertension (27.22%) and type 2 diabetes (15.82%), which were the two most common co-morbidities. (5) All the patients were given supportive therapy to prevent complications. They were also isolated for more than 5 days after onset, and at least for 24 hours after subsidence of fever in addition. (6) The criteria for the diagnosis of severe dengue were fulfilled in 18 patients (11.39%). One patient died of massive hemorrhage from gastro-intestinal tract, and 1 patient voluntarily left hospital with untreated multiple organ dysfunction syndrome (MODS

    The objective of this study was to identify patterns of fever and neutropenia in pediatric patients undergoing initial hospitalization for hematopoietic stem cell transplantation. A retrospective review of 75 HSCTs over a 4-year period at a single institution was performed, of which 68% were allogeneic and 32% were autologous. Stem cell sources included bone marrow (29%), PBSC (52%) and umbilical cord blood (16%). Fever occurred in 74 (98%) of the episodes. Unexplained fever (FUO) occurred in 43%. Bacteremia without an anatomic focus occurred in 29%, while CVC associated infections occurred in 17%. In 49% of transplants at least one blood culture was positive. The incidence of bacteremia was higher in allogeneic HSCTs (58%) than in autologous transplants (29%). Gram-positive bacteria accounted for 71% of the isolates. Lower rates of bacteremia were observed in patients receiving oral fluoroquinolone prophylaxis. The median duration of fever was 12.5 days and time to engraftment 14 days. Regression analysis demonstrated that duration of fever was strongly associated with time to engraftment, and that time to engraftment was associated with source of cells and number of CD34+ cells/kg administered. Recipients of autologous PBSC had the shortest durations of fever and time to engraftment, while recipients of allogeneic umbilical cord blood had the longest.

    The variations in meteorological conditions induced by climate change causes the diffusion pattern of infectious disease and serious epidemic situation. The objective of this study is to investigate the impact of meteorological variables to the temporal variation of dengue fever epidemic in weekly basis in south Taiwan. Several extreme and average index of meteorological variables, i.e. temperature and humidity, were used for this analysis, including averaged, maximum and minimum temperature, and average rainfall, maximum 1-hr rainfall, and maximum 24-hr rainfall. This study applies the distributed lag nonlinear model (DLNM) to reveal the significant meteorological variables and their temporal lag effects to the dengue fever epidemic by analyzing the dengue fever records from 1998-2011. Results show that the weekly minimum temperature (minT) and 1-hr maximum rainfall (maxR) are significantly important to the dengue fever spread. Among them, once minT is higher than 20°C, the relative risk of dengue fever of nine-fourteen week later will be significantly elevated. On the other hand, the incidences of maxR higher than 80mm can also increase the relative risk of dengue fever occurrences around nine-fourteen weeks afterwards.

    To describe the parental knowledge and care of fever in children under 2years. Relate this data with socio-demographic with characteristics. Cross-sectional and correlation multicenter study. Five teams of Primary Care in Barcelona. Parents of children under 2years attended to administer a vaccine included in the pediatric systematic calendar. A total of 311 subjects participated. The main variables are 9 items of knowledge and 8 of care or management of fever obtained with the adaptation of the questionnaire by Chiappini et al. (2012). 69.8% had a correct care/management of fever. 3.9% matched all items of knowledge. The knowledge score is lower in people with no education (p=0.03); higher in Europe and South America and lowest in Asia and Africa (P<.001). 100% of patients that had chronic problems answered correctly all items of fever care (P=.03). It is important to note that the correlation between the scores of knowledge and management is positive (rho=0.15, P=.008). A correct care of fever is observed despite the low knowledge. A good strategy to promote a correct care of febrile child is to do sanitary education with update information and adapted it to parents, focusing on the differences between ethnic groups because they seem to have inaccurate beliefs about fever.

    Typhoid vaccination is an important component of typhoid fever prevention and control, and is recommended for public health programmatic use in both endemic and outbreak settings. We reviewed experiences with various vaccination strategies using the currently available typhoid vaccines (injectable Vi polysaccharide vaccine [ViPS], oral Ty21a vaccine, and injectable typhoid conjugate vaccine [TCV]). We assessed the rationale, acceptability, effectiveness, impact and implementation lessons of these strategies to inform effective typhoid vaccination strategies for the future. Vaccination strategies were categorized by vaccine disease control strategy (preemptive use for endemic disease or to prevent an outbreak, and reactive use for outbreak control) and vaccine delivery strategy (community-based routine, community-based campaign and school-based). Almost all public health typhoid vaccination programs used ViPS vaccine and have been in countries of Asia, with one example in the Pacific and one experience using the Ty21a vaccine in South America. All vaccination strategies were found to be acceptable, feasible and effective in the settings evaluated; evidence of impact, where available, was strongest in endemic settings and in the short- to medium-term. Vaccination was cost-effective in high-incidence but not low-incidence settings. Experience in disaster and outbreak settings remains limited. TCVs have recently become available and none are WHO-prequalified yet; no program experience with TCVs was found in published literature. Despite the demonstrated success of several typhoid vaccination strategies, typhoid vaccines remain underused. Implementation lessons should be applied to design optimal vaccination strategies using TCVs which have several anticipated advantages, such as potential for use in infant immunization programs and longer duration of protection, over the ViPS and Ty21a vaccines for typhoid prevention and control.

    The purpose of this research was to compare the effects of a warm-up with static vs. dynamic stretching on countermovement jump (CMJ) height, reaction time, and low-back and hamstring flexibility and to determine whether any observed performance deficits would persist throughout a series of CMJs. Twenty-one recreationally active men (24.4 ± 4.5 years) completed 3 data collection sessions. Each session included a 5-minute treadmill jog followed by 1 of the stretch treatments: no stretching (NS), static stretching (SS), or dynamic stretching (DS). After the jog and stretch treatment, the participant performed a sit-and-reach test. Next, the participant completed a series of 10 maximal-effort CMJs, during which he was asked to jump as quickly as possible after seeing a visual stimulus (light). The CMJ height and reaction time were determined from measured ground reaction forces. A treatment × jump repeated-measures analysis of variance for CMJ height revealed a significant main effect of treatment (p = 0.004). The CMJ height was greater for DS (43.0 cm) than for NS (41.4 cm) and SS (41.9 cm) and was not less for SS than for NS. Analysis also revealed a significant main effect of jump (p = 0.005) on CMJ height: Jump height decreased from the early to the late jumps. The analysis of reaction time showed no significant effect of treatment. Treatment had a main effect (p flexibility, however. Flexibility was greater after both SS and DS compared to after NS, with no difference in flexibility between SS and DS. Athletes in sports requiring lower-extremity power should use DS techniques in warm-up to enhance flexibility while improving performance.

    Full Text Available Chloramphenicol inhibits protein synthesis in bacteria and is usually bacteriostatic but is bactericidal against Haemophilus influenzae, Streptococcus pneumoniae, and Neisseria meningitis. Chloramphenicol penetrates all body tissues well. The cerebrospinal fluid concentration averages 60% of the serum level, while brain levels are 9 times higher because of high lipid solubility of this drug. Chloramphenicol acts primarily by binding reversibly to the 50S ribosomal subunit. This antibiotic is the drug of choice for the treatment of typhoid and paratyphoid fevers and bacterial meningitis. Chloramphenicol possesses a broad-spectrum of antimicrobial activity. Strains are considered sensitive if they are inhibited by chloramphenicol concentrations of ≤ 8 µg/ml. Neisseria gonorrhea, Brucella species, Bordetella pertussis, gram-positive cocci, Clostridium species, and gram-negative rods including Bacillus fragilis are inhibited by chloramphenicol. Most anaerobic bacteria including Mycoplasma, Chlamydia, Rickettsiae, Vibrio cholera, Escherichia coli and Klebsiella pneumoniae are inhibited by this antibiotic. The doses of chloramphenicol are 40.5 mg/kg/day for neonates and 75.5 mg/kg/day for older children. The therapeutic concentrations of chloramphenicol are 10-25 µg/ml. Peak therapeutic concentrations are obtained in 60% and therapeutic trough concentrations are found in 42% of children. Children affected by typhoid fever are cu red by chloramphenicol and the sensitivity to this antibiotic is 100%. Acute bacterial meningitis is the most dangerous infections disease in children. The causative organisms are gram-positive and gram-negative bacteria, and chloramphenicol is effective in killing these microorganisms. The aim of this study is to review the management of typhoid fever and bacterial meningitis in infants and children by chloramphenicol.

    Full Text Available BACKGROUND Sickle Cell Disease (SCD poses a considerable health burden in India. The sickle gene is widespread among many tribal population groups in India with prevalence of heterozygotes varying from 1-40 percent. The disease has multiple acute and chronic complications, including haemolytic crises, severe pain, renal complications, thromboembolic phenomenon and overwhelming infections; some complications of SCD generate high mortality. MATERIALS AND METHODS This is a cross-sectional, hospital inpatient based, observational study. Convenience sampling technique was used to include 74 consecutively diagnosed cases of sickle cell disease children less than 14 years of age and suffering from fever. A blood culture was performed in each case prior to starting of antibiotics. RESULTS The present study comprised of 74 children with confirmed sickle cell disease admitted to ward with fever. The largest numbers of cases were between 1 to 3 years age group. Febrile episodes decreased as the age advanced. Around 30% of febrile patients presented with cough followed by 24% with pain in limbs. Anaemia was the most common physical finding (92% followed by splenomegaly in 86% cases. URTI being most common aetiology. Most common organism isolated by blood culture was Staph. aureus in 8 samples. CONCLUSION As because fever is a consistent finding in severe bacterial infections, extensive evaluation, early intervention in febrile SCD children may reduce the morbidity and mortality rates. Although, the greatest concern has traditionally been S. pneumoniae, effective vaccination has reduced its incidence. It is probably wise to treat all highly febrile children with sickle cell disease with antibiotics pending the results of blood culture. Strengthening of routine immunisation programme is needed.

    Ebola zoonotic RNA filovirus represents human most virulent and lethal pathogens, which induces acute hemorrhagic fever and death within few days in a range of 60-90% of symptomatic individuals. Last outbreak in 2014 in West Africa caused panic that Ebola epidemic can be spread to other continents. Number of deaths in late December reached almost 8,000 individuals out of more than 20,000 symptomatic patients. It seems that only a coordinated international response could counteract the further spread of Ebola. Major innate immunity mechanisms against Ebola are associated with the production of interferons, that are inhibited by viral proteins. Activation of host NK cells was recognized as a leading immune function responsible for recovery of infected people. Uncontrolled cell infection by Ebola leads to an impairment of immunity with cytokine storm, coagulopathy, systemic bleeding, multi-organ failure and death. Tested prevention strategies to induce antiviral immunity include: i. recombinant virus formulations (vaccines); ii. cocktail of monoclonal antibodies (serotherapy); iii. alternative RNA-interference-based antiviral methods. Maintaining the highest standards of aseptic and antiseptic precautions is equally important. Present brief review summarizes a current knowledge concerning pathogenesis of Ebola hemorrhagic disease and the virus interaction with the immune system and discusses recent advances in prevention of Ebola infection by vaccination and serotherapy.

    Acute rheumatic fever and its sequels, rheumatic heart diseases, remain major unsolved preventable health problems in Kosovo population, particularly among the disadvantages indigenous Albanian and Egyptians people. In Kosovo, despite of performing secondary prophylaxis with benzathine penicillin, acute rheumatic fever hospitalization rates have remained essentially unchanged for the last 20 years. The role of echocardiography in the diagnosis of acute rheumatic carditis was established over the last 20 years. In this study we aimed to determine the prevalence of rheumatic heart disease in children from Kosovo population with first attack of acute rheumatic fever. Also, we presented that echocardiography examination detects a greater prevalence of rheumatic heart disease than other diagnostic procedures. We aimed to compare the sensitivity and specificity of cardiac auscultation, ECG record, lab analysis to echocardiography and to determine the feasibility of specific age in this setting. To optimize accurate diagnosis of rheumatic fever and rheumatic heart disease, we utilized two group models. In the first group of 388 children, hospitalized and treated before 1999, diagnosis of rheumatic fever was decided basing on the clinical and laboratory findings whereas in second group (221 children treated from1999 to 2010) clinical and lab diagnosis were amplified also on the detection by echocardiography. In second group, using echocardiography as a method of diagnosis and assessment children with rheumatic fever, we found high rates of undetected rheumatic heart disease in this high-risk group population. Echocardiographic examination of children with rheumatic fever for rheumatic heart disease may over diagnose rheumatic heart disease unless congenital mitral valve anomalies and physiological regurgitation are excluded.

    Fever and leukocytosis have many possible etiologies in injection drug users. We present a case of a 22-year-old woman with fever and leukocytosis that were presumed secondary to cotton fever, a rarely recognized complication of injection drug use, after an extensive workup. Cotton fever is a benign, self-limited febrile syndrome characterized by fevers, leukocytosis, myalgias, nausea and vomiting, occurring in injection drug users who filter their drug suspensions through cotton balls. While this syndrome is commonly recognized amongst the injection drug user population, there is a paucity of data in the medical literature. We review the case presentation and available literature related to cotton fever.

    Objective: To verify if the Bio-Manguinhos 17DD yellow fever vaccine (17DD-YFV) used in lower doses is as immunogenic and safe as the current formulation. Results: Doses from 27,476 IU to 587 IU induced similar seroconversion rates and neutralizing antibodies geometric mean titers (GMTs). Immunity of those who seroconverted to YF was maintained for 10 mo. Reactogenicity was low for all groups. Methods: Young and healthy adult males (n = 900) were recruited and randomized into 6 groups, to receive de-escalating doses of 17DD-YFV, from 27,476 IU to 31 IU. Blood samples were collected before vaccination (for neutralization tests to yellow fever, serology for dengue and clinical chemistry), 3 to 7 d after vaccination (for viremia and clinical chemistry) and 30 d after vaccination (for new yellow fever serology and clinical chemistry). Adverse events diaries were filled out by volunteers during 10 d after vaccination. Volunteers were retested for yellow fever and dengue antibodies 10 mo later. Seropositivity for dengue was found in 87.6% of volunteers before vaccination, but this had no significant influence on conclusions. Conclusion: In young healthy adults Bio-Manguinhos/Fiocruz yellow fever vaccine can be used in much lower doses than usual. International Register ISRCTN 38082350. PMID:23364472

    Dengue hemorrhagic fever is a more serious form of disease characterised by plasma leakage syndrome, thrombocytopenia and disseminated intravascular coagulation. We present a 51 year old male who presented with fever, petechiae and acute onset of breathlessness. Emergency chest rhoentogram showed a massive right sided pleural effusion. On insertion of intercostal drain, there was a sudden gush of blood tinged fluid suggestive of hemothorax. There was no history of trauma or bleeding tendencies. Laboratory investigations revealed a raised hematocrit and severe thrombocytopenia. Dengue IgM was surprisingly positive. After aggressive supportive management the patient gradually improved and was discharged. While bilateral pleural effusion is a known occurrence in dengue hemorrhagic fever, massive hemothorax is unheard of. We report the first case in literature of dengue hemorrhagic fever presenting as unilateral massive hemothorax. A suspicion of dengue must also be borne in mind in cases of non-traumatic hemothorax especially in endemic areas. Copyright © 2012 Hainan Medical College. Published by Elsevier B.V.

    Lassa fever is a potentially fatal acute viral illness caused by Lassa virus which is carried by rodents and is endemic in some West African countries. Importation of emerging infections such as Lassa fever, Ebola Virus Disease and other viral hemorrhagic fevers into non endemic regions is a growing threat particularly as international travel and commitments in resolving conflicts in endemic countries in the West Africa sub-region continue. We report the first two recorded imported cases of Lassa fever among Ghanaian Peace keepers in rural Liberia, who became ill while on Peace keeping mission. They were subsequently evacuated to the UN level IV hospital in Accra, where their illnesses were laboratory confirmed. One of the patients recovered with ribavirin treatment and supportive therapy. No secondary clinical cases occurred in Ghana. Healthcare providers at all levels of care should thus have a high index of suspicion for these infectious diseases and adopt standard infection control measures when treating patients in endemic regions or returning travelers from an endemic region with a febrile illness even of a known etiology.

    The pharmacological specificities of the rectal formulation of acetaminophen led to a debate on its appropriateness for managing fever in children, but few data are available on the formulation's current use and determinants of use. In a national cross-sectional study between 2007 and 2008, healthcare professionals were asked to include five consecutive patients with acute fever. Among the 6255 children (mean age 4.0 years ± 2.8 SD) who received acetaminophen given by parents or prescribed/recommended by healthcare professionals, determinants of suppository use were studied by multilevel models. A suppository was given by 27 % of parents and prescribed/recommended by 19 % of healthcare professionals, by 24 and 16 %, respectively, for children 2 to 5 years old, and by 13 and 8 %, respectively, for those 6 to 12 years old. Among children who received suppositories from parents and healthcare professionals, 83 and 84 %, respectively, did not vomit. Suppository use was independently associated with several patient- and healthcare professional-level characteristics: young age of children, presence of vomiting, or lack of diarrhea. We report an enduring large use of suppositories in France for the symptomatic management of fever in children, including in non-vomiting and/or older children. The rational for such use should be questioned. • The pharmacological specificities of the rectal formulation of acetaminophen have led to a debate on its appropriateness for managing fever in children. Few data are available on the formulation's current use and determinants of the use. What is New: • In a national cross-sectional study, we observed a large use of suppositories in France for symptomatic management of fever in children. Suppositories were frequently used for the youngest children but also for older and/or non-vomiting children.

    Detailed ultrastructural studies of Rift Valley fever virus (RVFV) in the mouse model are needed to develop and characterize a small animal model of RVF for the evaluation of potential vaccines and therapeutics. In this study, the ultrastructural features of RVFV infection in the mouse model were analyzed. The main changes in the liver included the presence of viral particles in hepatocytes and hepatic stem cells accompanied by hepatocyte apoptosis. However, viral particles were observed rarely in the liver; in contrast, particles were extremely abundant in the CNS. Despite extensive lymphocytolysis, direct evidence of viral replication was not observed in the lymphoid tissue. These results correlate with the acute-onset hepatitis and delayed-onset encephalitis that are dominant features of severe human RVF, but suggest that host immune-mediated mechanisms contribute significantly to pathology. The results of this study expand our knowledge of RVFV–host interactions and further characterize the mouse model of RVF.

    Meticulous fluid management is the mainstay of treatment in dengue fever that is currently governed by consensus guidelines rather than by strong research evidence. To examine this issue we audited the fluid requirement of a cohort of adult patients with dengue fever (DF) and dengue haemorrhagic fever (DHF) in a tertiary care clinical setting. This retrospective cohort study was conducted from July 2012 to January 2013 in Teaching Hospital, Peradeniya, Sri Lanka. Adult patients with confirmed dengue infection managed according to the national and WHO guidelines were included. Their fluid requirement was audited once data collection was over in both DF and DHF groups. Out of 302 patients, 209 (69%) had serological confirmation of dengue infection, comprising 62 (30%) patients gone into critical phase of DHF. Mean age of the DHF group was 30 years (range 12-63 years) and included more males (n = 42, 68%, p fever on admission and total duration of fever were 4 days and 6 days respectively. DHF group had high incidence of vomiting, abdominal pain and flushing, lowest platelet counts and highest haematocrit values compared to DF group. In DHF group, the mean total daily requirements of fluid from 2(nd) to 7(th) day were 2123, 2733, 2846, 2981, 3139 and 3154 milliliters respectively to maintain a safe haematocrit value and the vital parameters. However, in DF group the fluid requirement was lowest on 3(rd) day (2158 milliliters). DHF group had significantly high fluid requirement on 5(th) -7(th) day compared to DF group (p fever and again on 5(th) to 7(th) day of fever. Despite being an audit, these finding could be useful in future updates of guidelines and designing research.

  6. Use of optical coherence tomography to evaluate visual acuity and visual field changes in dengue fever.

    Rhee, Taek Kwan; Han, Jung Il

    2014-02-01

    Dengue fever is a viral disease that is transmitted by mosquitoes and affects humans. In rare cases, dengue fever can cause visual impairment, which usually occurs within 1 month after contracting dengue fever and ranges from mild blurring of vision to severe blindness. Visual impairment due to dengue fever can be detected through angiography, retinography, optical coherence tomography (OCT) imaging, electroretinography, event electroencephalography (visually evoked potentials), and visual field analysis. The purpose of this study is to report changes in the eye captured using fluorescein angiography, indocyanine green, and OCT in 3 cases of dengue fever visual impairment associated with consistent visual symptoms and similar retinochoroidopathic changes. The OCT results of the three patients with dengue fever showed thinning of the outer retinal layer and disruption of the inner segment/outer segment (IS/OS) junction. While thinning of the retina outer layer is an irreversible process, disruption of IS/OS junction is reported to be reversible. Follow-up examination of individuals with dengue fever and associated visual impairment should involve the use of OCT to evaluate visual acuity and visual field changes in patients with acute choroidal ischemia.

    Herein we have described the case of a male renal transplant recipient who developed drug fever apparently related to sirolimus. He had been stable under an immunosuppressive regimen of tacrolimus and mycophenolate mofetil, but developed acute cellular rejection at 5 years after transplantation due to noncompliance. Renal biopsy showed marked interstitial fibrosis, and immunosuppression was switched from mycophenolate to sirolimus, maintaining low tacrolimus levels. One month later he was admitted to our hospital for investigation of intermittently high fever, fatigue, myalgias, and diarrhea. Physical examination was unremarkable and drug levels were not increased. Lactic dehydrogenase and C-reactive protein were increased. The blood cell count and chest radiographic findings were normal. After extensive cultures, he was started on broad-spectrum antibiotics. Inflammatory markers and fever worsened, but diarrhea resolved. All serologic and imaging tests excluded infection, immune-mediated diseases, and malignancy. After 12 days antibiotics were stopped as no clinical improvement was achieved. Drug fever was suspected; sirolimus was replaced by mycophenolate mofetil. Fever and other symptoms disappeared after 24 hours; inflammatory markers normalized in a few days. After 1 month the patient was in good health with stable renal function. Although infrequent, the recognition of drug fever as a potential side effect of sirolimus may avoid unnecessary invasive diagnostic procedures. Nevertheless, exclusion of other common causes of fever is essential.

    Dengue fever, a tropical disease once confined mostly to endemic areas in developing countries, is becoming more prevalent. Globalization has led to an increased incidence of the virus both in foreign travelers returning home and local outbreaks in traditionally nonendemic areas, such as the southern United States and southern Europe. Advances in diagnostic tests, therapies, and vaccines for dengue virus have been limited, but research is ongoing. To review the current literature regarding the diagnosis and management of dengue fever. This case report describes a young woman returning from Central America with many of the common signs and symptoms who was misdiagnosed both abroad and at home. We explore the epidemiology, disease course, complications, and treatment of dengue fever. Emergency physicians should consider dengue fever in patients with acute febrile illnesses, especially among those with recent travel. Copyright © 2013 Elsevier Inc. All rights reserved.

    We report the case of a 33-year-old woman returning from Haiti, presenting to our emergency department (ED) with fever, rash and arthralgia. Following a broad workup that included laboratory testing for dengue and malaria, our patient was diagnosed with Chikungunya virus, which was then reported to the Centers for Disease Control and Prevention for initiation of infection control. This case demonstrates the importance of the ED for infectious disease case identification and initiation of public health measures. This case also addresses public health implications of Chikungunya virus within the United States, and issues related to the potential for local spread and autochthonous cases.

    Acute hemorrhagic edema of infancy is a rare but benign vasculitis occurring in infants aged from 4 to 24 months. Skin lesions can take various forms, including extensive hemorrhagic purpura, and can therefore be mistaken for purpura fulminans if associated with fever, which leads to initiating broad-spectrum antibiotic treatment. In the present case, we describe a 7-month-old boy with acute hemorrhagic edema of infancy and rapidly extensive purpura lesions that led to intravenous cefotaxime and amikacin treatment. Diagnosis was made on the next day by a dermatologist, based on the typical aspect of skin lesions, hemodynamic stability, and negative bacteriological samples. Coxsackie virus B5, a pathogenic enterovirus, was found by specific PCR in cerebrospinal fluid. The outcome was spontaneously favorable after discontinuation of antibiotics on day 2. We discuss the imputability of the enterovirus in triggering this case of acute hemorrhagic edema of infancy. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

    Fever is common in malignant tumors. We report an exceptional case of psychogenic fever in a patient with small cell lung cancer. This is the first case report of psychogenic fever in a patient with small cell lung cancer. A 61-year-old Chinese man diagnosed with small cell carcinoma on June 30, 2012, came to our department with a complaint of fever lasting more than 1 month. He had undergone chemoradiotherapy for lung cancer 6 months previously. After admission, his body temperature fluctuated in the range of 37 °C to 39 °C. Somatic symptoms associated with anxiety were obvious. A 24-item Hamilton Anxiety Scale was used to assess the patient’s condition. A score of 32 confirmed a diagnosis of severe anxiety. After a week of antianxiety treatment, the patient’s temperature returned to normal. Psychogenic fever is common in cancer patients and deserves more attention. Patients with psychogenic fever must be distinguished from patients with infectious fever (including neutropenic fever), and tumor fever. Additionally, antianxiety or antidepression treatment should be provided. A concern is that continual anxiety may adversely affect anticancer therapy

The disease is usually diagnosed before 20 years of age. Symptoms related to FMF are noted when children become more verbal, usually after 2 years of age. In this case report, the youngest patient with the diagnosis of FMF is presented. She was consulted to pediatric rheumatology for the high acute phase response and fever. It was learned that her mother had recurrent swelling of her ankle joints. Mutation analysis was performed and two homozygous mutations (M694V and R202Q were identified. She was diagnosed as FMF at 3 months of age and colchicine was started. She responded to colchicine. Her uncontrolled acute phase response declined gradually. This case was reported to point out the importance of early remembrance of autoinflammatory diseases even at very early ages especially at endemic countries.

    Dengue Fever is caused by arthropod born viruses. According to World Health Organization approximately 50-100 million infections of dengue fever occur yearly. Objective of this study was to determine the frequency of splenomegaly in dengue fever in children. This cross sectional study was conducted at the Department of Paediatrics, Allied Hospital, Faisalabad, during a period from June 2012 to May 2013 by including 93 Children, aged 4-14 years presenting with fever of less than 14 days with thrombocytopenia and positive IM or IgM and IgG dengue antibodies by ELISA. Patients were thoroughly evaluated by detailed history and clinical examination. Ultrasonography of the patients was performed to confirm the splenomegaly. The data was analysed to determine the frequency and percentage of disease. Out of 93 children, 51 (54.8%) were male and 42 (45.2%) were female. The most common clinical presentation was noted is chills and rigors in 80 (86.02%). Unusual clinical features were encephalopathy in 3T (39.78%) followed by bleeding manifestations and upper respiratory tract infection (upper RTI). Splenomegaly was seen in 45 (48.4%) children. Dengue fever is increasingly presenting with atypical presentation like splenomegaly, encephalopathy, bleeding manifestations and upper RTI.

    Full Text Available Abstract Background Malaria remains a major public health problem in Sub Saharan Africa, where widespread poverty also contribute to the burden of the disease. This study was designed to investigate the relationship between the prevalence of childhood fever and socioeconomic factors including poverty in Nigeria, and to examine these effects at the regional levels. Methods Determinants of fever in the last two weeks among children under five years were examined from the 25004 children records extracted from the Nigeria Demographic and Health Survey 2008 data set. A two-level random effects logistic model was fitted. Results About 16% of children reported having fever in the two weeks preceding the survey. The prevalence of fever was highest among children from the poorest households (17%, compared to 15.8% among the middle households and lowest among the wealthiest (13% (p6months, whereas the effect of wealth no longer reached statistical significance. Conclusion While, overall bednet possession was low, less fever was reported in households that possessed bednets. Malaria control strategies and interventions should be designed that will target the poor and make an impact on poverty. The mechanism through which wealth may affect malaria occurrence needs further investigation.

    Objective: This pilot study examined the laboratory responses of patients with laboratory-documented typhoid fever who were treated with Biomagnetic Pair Therapy (BPT; medical biomagnetism), a specific application of pairs of magnets for various ailments that are infectious and otherwise. Materials and Methods: This study was an assessment of patients' response to treatment with only BPT for Salmonella typhi infections (typhoid fever) using standard conventional laboratory techniques. The research was conducted in an outpatient village clinic in Kenya. There were 52 participants who were evaluated for possible systemic illness, including typhoid fever, from an open-label study. Participants who felt sick and requested testing for possible typhoid fever were tested with a standard Widal test by a certified laboratory technician. Participants who tested positive (13 patients) were then treated with BPT (a "First Aid" approach) only. These participants then returned for follow-up laboratory and clinical evaluations after 2 days. Results: Most of the participants (10 of 13) retested as negative, and all patients reported symptomatic clinical improvement. Conclusions: As a significant majority of participants demonstrated clearing of their S. typhi after BPT, this technique should be studied further in larger trials for its efficacy in treating typhoid fever.

    Full Text Available Abhinay Sharma, D Patric Nitsche-SchmitzDepartment of Medical Microbiology, Helmholtz Center for Infection Research, Braunschweig, GermanyAbstract: Acute rheumatic fever is a sequela of Streptococcus pyogenes and potentially of Streptococcus dysgalactiae subsp. equisimilis infections. Acute rheumatic fever is caused by destructive autoimmunity and inflammation in the extracellular matrix and can lead to rheumatic heart disease, which is the most frequent cardiologic disease that is acquired in youth. Although effective treatments are available, acute rheumatic fever and rheumatic heart disease remain serious threats to human health, which affect millions and cause high economic losses. This has motivated the search for a vaccine that prevents the causative streptococcal infections. A variety of potential vaccine candidates have been identified and investigated in the past. Today, new approaches are applied to find alternative candidates. Nevertheless, several obstacles lie in the way of an approved S. pyogenes vaccine for use in humans. Herein, a subjective selection of promising vaccine candidates with respect to the prevention of acute rheumatic fever/rheumatic heart disease and safety regarding immunological side effects is discussed.Keywords: autoimmune disease, side effects, M protein vaccine, molecular mimicry, coiled-coil, collagen binding, PARF

    Chikungunya fever is an emerging disease caused by an alphavirus belonging to the Togaviridae family, transmitted by the bite of Aedes genus species: Aedesaegypti and Aedesalbopictus. In 2013, PAHO/WHO received confirmation of the first cases of indigenous transmission of chikungunya in the Americas. This disease may be acute, subacute and chronic, affecting all age groups. Following an incubation period from three to seven days, the patient usually begins with a high fever (greater than 39 °C), arthralgia, back pain, headache, nausea, vomiting, arthritis, rash, and conjunctivitis (acute phase: 3-10 days). Most patients recover fully, but in some cases, joint involvement may persist chronically and cause discapacity and affect life quality. Serious complications are rare, however, attention must be focused on vulnerable populations (the elderly, children and pregnant women). So far, there is no specific antiviral treatment or effective vaccine, so it is giving priority symptomatic and supportive treatment for the acute phase and make an early diagnosis of atypical and severe forms, and to implement effective prevention and control measures. Given the eco-epidemiological conditions and distribution of vectors in the region of the Americas, the spread of the virus to other countries is likely, so that health professionals should be aware of and identify risk factors and major clinical manifestations, allow timely prevention and safe and effective treatment of this disease.

    Recognition that the live yellow fever vaccine may rarely be associated with viscerotropic disease (YEL-AVD) has diminished its safety status. However, the vaccine remains the principal tool for limiting the occurrence of yellow fever, making large portions of Africa and South America more habitable. The subject has previously been exhaustively reviewed. Novel concepts in the current report include the description of a systematic method for deciding whom to vaccinate, recommendations for obtaining data helpful in making that decision, and suggestions for additional study. The vaccine is indeed a worthy friend, but its adverse reactions need to be recognized.

    Fever is one of the most common adverse events of vaccines. The detailed mechanisms of fever and vaccine-associated gene interaction networks are not fully understood. In the present study, we employed a genome-wide, Centrality and Ontology-based Network Discovery using Literature data (CONDL) approach to analyse the genes and gene interaction networks associated with fever or vaccine-related fever responses. Over 170,000 fever-related articles from PubMed abstracts and titles were retrieved and analysed at the sentence level using natural language processing techniques to identify genes and vaccines (including 186 Vaccine Ontology terms) as well as their interactions. This resulted in a generic fever network consisting of 403 genes and 577 gene interactions. A vaccine-specific fever sub-network consisting of 29 genes and 28 gene interactions was extracted from articles that are related to both fever and vaccines. In addition, gene-vaccine interactions were identified. Vaccines (including 4 specific vaccine names) were found to directly interact with 26 genes. Gene set enrichment analysis was performed using the genes in the generated interaction networks. Moreover, the genes in these networks were prioritized using network centrality metrics. Making scientific discoveries and generating new hypotheses were possible by using network centrality and gene set enrichment analyses. For example, our study found that the genes in the generic fever network were more enriched in cell death and responses to wounding, and the vaccine sub-network had more gene enrichment in leukocyte activation and phosphorylation regulation. The most central genes in the vaccine-specific fever network are predicted to be highly relevant to vaccine-induced fever, whereas genes that are central only in the generic fever network are likely to be highly relevant to generic fever responses. Interestingly, no Toll-like receptors (TLRs) were found in the gene-vaccine interaction network. Since

    Full Text Available Arboviruses are maintained in a natural cycle that requires blood-sucking arthropod and vertebrate hosts. Arboviruses are believed to persistently infect their arthropod host without overt pathology and cause acute infection with viremia in their vertebrate host. We have focused on elucidating how a specific arbovirus, Rift Valley fever (RVF virus, causes cytopathic effect in cells derived from vertebrates and non-cytopathic infection in cells derived from arthropods. We demonstrate that the vertebrate virulence factor, NSs, is functional in arthropod cells but is expressed at significantly lower levels in infected arthropod versus infected vertebrate cells.

    Chikungunya fever is an acute febrile illness associated with severe, often debilitating polyarthralgias. The disease is caused by the Chikungunya virus (CHIKV), an arthropod-borne virus that is transmitted to humans primarily via the bite of an infected mosquito. Since a re-emergence of CHIKV in 2004 in the Indian Ocean islands, the virus has spread into novel locations such as Europe. In Italy, an outbreak occurred in 2007. A mutation in CHIKV (E1-A226V) appears to improve virus survival in Ae. albopictus and also increase its virulence. Further attention should be given the disease since it is emerging in Europe.

    On April 23, 2016, the Democratic Republic of the Congo's (DRC's) Ministry of Health declared a yellow fever outbreak. As of May 24, 2016, approximately 90% of suspected yellow fever cases (n = 459) and deaths (45) were reported in a single province, Kongo Central Province, that borders Angola, where a large yellow fever outbreak had begun in December 2015. Two yellow fever mass vaccination campaigns were conducted in Kongo Central Province during May 25-June 7, 2016 and August 17-28, 2016. In June 2016, the DRC Ministry of Health requested assistance from CDC to control the outbreak. As of August 18, 2016, a total of 410 suspected yellow fever cases and 42 deaths were reported in Kongo Central Province. Thirty seven of the 393 specimens tested in the laboratory were confirmed as positive for yellow fever virus (local outbreak threshold is one laboratory-confirmed case of yellow fever). Although not well-documented for this outbreak, malaria, viral hepatitis, and typhoid fever are common differential diagnoses among suspected yellow fever cases in this region. Other possible diagnoses include Zika, West Nile, or dengue viruses; however, no laboratory-confirmed cases of these viruses were reported. Thirty five of the 37 cases of yellow fever were imported from Angola. Two-thirds of confirmed cases occurred in persons who crossed the DRC-Angola border at one market city on the DRC side, where ≤40,000 travelers cross the border each week on market day. Strategies to improve coordination between health surveillance and cross-border trade activities at land borders and to enhance laboratory and case-based surveillance and health border screening capacity are needed to prevent and control future yellow fever outbreaks.

    A number of viruses in the family Flaviviridae are the focus of efforts to develop effective antiviral therapies. Success has been achieved with inhibitors for the treatment of hepatitis C, and there is interest in clinical trials of drugs against dengue fever. Antiviral therapies have also been evaluated in patients with Japanese encephalitis and West Nile encephalitis. However, no treatment has been developed against the prototype flavivirus, yellow fever virus (YFV). Despite the availability of the live, attenuated 17D vaccine, thousands of cases of YF continue to occur each year in Africa and South America, with a significant mortality rate. In addition, a small number of vaccinees develop severe systemic infections with the 17D virus. This paper reviews current efforts to develop antiviral therapies, either directly targeting the virus or blocking detrimental host responses to infection. PMID:23237991

    2016-01-01

    Full Text Available Dengue is a highly endemic infectious disease of the tropical countries and is rapidly becoming a global burden. It is caused by any of the 4 serotypes of dengue virus and is transmitted within humans through female Aedes mosquitoes. Dengue disease varies from mild fever to severe conditions of dengue hemorrhagic fever and shock syndrome. Globalization, increased air travel, and unplanned urbanization have led to increase in the rate of infection and helped dengue to expand its geographic and demographic distribution. Dengue vaccine development has been a challenging task due to the existence of four antigenically distinct dengue virus serotypes, each capable of eliciting cross-reactive and disease-enhancing antibody response against the remaining three serotypes.

    Dengue is a highly endemic infectious disease of the tropical countries and is rapidly becoming a global burden. It is caused by any of the 4 serotypes of dengue virus and is transmitted within humans through female Aedes mosquitoes. Dengue disease varies from mild fever to severe conditions of dengue hemorrhagic fever and shock syndrome. Globalization, increased air travel, and unplanned urbanization have led to increase in the rate of infection and helped dengue to expand its geographic and demographic distribution. Dengue vaccine development has been a challenging task due to the existence of four antigenically distinct dengue virus serotypes, each capable of eliciting cross-reactive and disease-enhancing antibody response against the remaining three serotypes.

    The country of Fiji, with a population of approximately 870 000 people, faces a growing burden of several communicable diseases including the bacterial infection typhoid fever. Surveillance data suggest that typhoid has become increasingly common in rural areas of Fiji and is more frequent amongst young adults. Transmission of the organisms that cause typhoid is facilitated by faecal contamination of food or water and may be influenced by local behavioural practices in Fiji. The Fijian Ministry of Health, with support from Australian Aid, hosted a meeting in August 2012 to develop comprehensive control and prevention strategies for typhoid fever in Fiji. International and local specialists were invited to share relevant data and discuss typhoid control options. The resultant recommendations focused on generating a clearer sense of the epidemiology of typhoid in Fiji and exploring the contribution of potential transmission pathways. Additionally, the panel suggested steps such as ensuring that recommended ciprofloxacin doses are appropriate to reduce the potential for relapse and reinfection in clinical cases, encouraging proper hand hygiene of food and drink handlers, working with water and sanitation agencies to review current sanitation practices and considering a vaccination policy targeting epidemiologically relevant populations. © 2014 The Authors.

    Full Text Available Children bear a large burden of typhoid fever caused by Salmonella enterica serotype Typhi (S. Typhi in endemic areas. However, immune responses and clinical findings in children are not well defined. Here, we describe clinical and immunological characteristics of young children with S. Typhi bacteremia, and antimicrobial susceptibility patterns of isolated strains.As a marker of recent infection, we have previously characterized antibody-in-lymphocyte secretion (TPTest during acute typhoid fever in adults. We similarly assessed membrane preparation (MP IgA responses in young children at clinical presentation, and then 7-10 days and 21-28 days later. We also assessed plasma IgA, IgG and IgM responses and T cell proliferation responses to MP at these time points. We compared responses in young children (1-5 years with those seen in older children (6-17 years, adults (18-59 years, and age-matched healthy controls.We found that, compared to age-matched controls patients in all age cohorts had significantly more MP-IgA responses in lymphocyte secretion at clinical presentation, and the values fell in all groups by late convalescence. Similarly, plasma IgA responses in patients were elevated at presentation compared to controls, with acute and convalescent IgA and IgG responses being highest in adults. T cell proliferative responses increased in all age cohorts by late convalescence. Clinical characteristics were similar in all age cohorts, although younger children were more likely to present with loss of appetite, less likely to complain of headache compared to older cohorts, and adults were more likely to have ingested antibiotics. Multi-drug resistant strains were present in approximately 15% of each age cohort, and 97% strains had resistance to nalidixic acid.This study demonstrates that S. Typhi bacteremia is associated with comparable clinical courses, immunologic responses in various age cohorts, including in young children, and that TPTest

    Full Text Available Mosquito-borne Rift Valley fever virus (RVFV causes acute, often severe, disease in livestock and humans. To determine the exposure factors and range of symptoms associated with human RVF, we performed a population-based cross-sectional survey in six villages across a 40 km transect in northeastern Kenya.A systematic survey of the total populations of six Northeastern Kenyan villages was performed. Among 1082 residents tested via anti-RVFV IgG ELISA, seroprevalence was 15% (CI95%, 13-17%. Prevalence did not vary significantly among villages. Subject age was a significant factor, with 31% (154/498 of adults seropositive vs. only 2% of children ≤15 years (12/583. Seroprevalence was higher among men (18% than women (13%. Factors associated with seropositivity included a history of animal exposure, non-focal fever symptoms, symptoms related to meningoencephalitis, and eye symptoms. Using cluster analysis in RVFV positive participants, a more severe symptom phenotype was empirically defined as having somatic symptoms of acute fever plus eye symptoms, and possibly one or more meningoencephalitic or hemorrhagic symptoms. Associated with this more severe disease phenotype were older age, village, recent illness, and loss of a family member during the last outbreak. In multivariate analysis, sheltering livestock (aOR = 3.5 CI95% 0.93-13.61, P = 0.065, disposing of livestock abortus (aOR = 4.11, CI95% 0.63-26.79, P = 0.14, and village location (P = 0.009 were independently associated with the severe disease phenotype.Our results demonstrate that a significant proportion of the population in northeastern Kenya has been infected with RVFV. Village and certain animal husbandry activities were associated with more severe disease. Older age, male gender, herder occupation, killing and butchering livestock, and poor visual acuity were useful markers for increased RVFV infection. Formal vision testing may therefore prove to be a helpful, low-technology tool

    The Chikungunya is an arbovirus first described during a 1952 outbreak of febrile exantematic disease in southern Tanganyika (now Tanzania). It is a virus within the alphavirus genus of the Togaviridae family, it is usually transmitted to humans by Aedes mosquitoes. Typically, the disease manifests as acute onset of fever and joint pains. This study describes the clinical characteristics the first imported case infected with chikungunya fever (CHIK) in Hermosillo, Sonora, Mexico. We report the case of a 30 years old man seen in our emergency department due to fever, polyarthralgia, rash and headache. This patient has been in Tapachula, Chiapas, a jungle area in southern México, and he returned from a 45 days trip before the onset his symptoms. The chikungunya viral infection (CHIK) was diagnosed by RT-PCR procedure. Paracetamol therapy was administered and his clinical course was self-limited. We concluded that with the increase of mosquito´s habitat by global warming and frequent traveling, CHIK reemerged and showed global distribution recently. This disease must be suspected in patients with compatible clinical symptoms returning from epidemic/endemic areas. CHIK must be diagnosed on the basis of clinical, epidemiological and laboratory criteria.

    Chikungunya virus (CHIKV) is the aetiological agent of the mosquito-borne disease chikungunya fever, a debilitating arthritic disease that, during the past 7years, has caused immeasurable morbidity and some mortality in humans, including newborn babies, following its emergence and dispersal out of Africa to the Indian Ocean islands and Asia. Since the first reports of its existence in Africa in the 1950s, more than 1500 scientific publications on the different aspects of the disease and its causative agent have been produced. Analysis of these publications shows that, following a number of studies in the 1960s and 1970s, and in the absence of autochthonous cases in developed countries, the interest of the scientific community remained low. However, in 2005 chikungunya fever unexpectedly re-emerged in the form of devastating epidemics in and around the Indian Ocean. These outbreaks were associated with mutations in the viral genome that facilitated the replication of the virus in Aedes albopictus mosquitoes. Since then, nearly 1000 publications on chikungunya fever have been referenced in the PubMed database. This article provides a comprehensive review of chikungunya fever and CHIKV, including clinical data, epidemiological reports, therapeutic aspects and data relating to animal models for in vivo laboratory studies. It includes Supplementary Tables of all WHO outbreak bulletins, ProMED Mail alerts, viral sequences available on GenBank, and PubMed reports of clinical cases and seroprevalence studies.

    Severe fever with thrombocytopenia syndrome (SFTS) associated with severe fever with thrombocytopenia syndrome virus (SFTSV) is an emerging infectious disease. 12 patients with severe fever with thrombocytopenia syndrome in our study were presented mainly with fever and severe malaise. The clinical manifestations typically became worse on the 6th or 7th day. The average fever time is 9.11 ± 1.54 days. Most of them had multiorgan dysfunction, and part of them had hemophagocytic lymphohistiocytosis histiocytosis (HLH). The characteristic laboratory findings in the early stage were the drop of white blood cells (WBC), platelets (PLT) and serum Ca++, while increase of aspartate amino transferase (AST), creatine kinase (CK), and lactate dehydrogenase (LDH). CD3+CD4+ were significantly decreased, while CD3-CD56+ were significantly increased, whereas CD3+CD8+ were constantly elevated throughout the disease course. Ten to 14 days after illness onset, symptoms were improved, accompanied by resolution of laboratory abnormalities. These results indicate that severe fever with thrombocytopenia syndrome has an acute onset and self-limited course. It is a systemic infection. The host immune response caused tissues and organs injury. The improvement of symptoms and laboratory tests is consistent with the elimination of the virus and recover of immune response. Further investigation should be done in order to better understand this disease and guide the clinical treatment. Copyright © 2013 Elsevier Editora Ltda. All rights reserved.

    Yellow fever is an important and potentially fatal infection in tropical regions of Africa, South America, eastern Panama in Central America and Trinidad in the Caribbean. Yellow fever vaccination is not only crucial to reduce the disease risk and mortality in individuals travelling to these areas, but also an important public health measure to prevent the spread of the disease. Despite generally considered as a safe vaccine, yellow fever vaccine can rarely be associated with severe adverse reactions including yellow fever vaccine-associated viscerotropic disease (YEL-AVD). Here, we report the first case of YEL-AVD in Hong Kong. Clinicians should alert to the possibility of YEL-AVD in vaccinees presenting with compatible symptoms after yellow fever vaccination, particularly in people at higher risk of adverse events. © International Society of Travel Medicine, 2016.

    2015-01-01

    Dengue virus is transmitted between humans and mosquitoes of the genus Aedes and causes approximately 96 million cases of disease (dengue fever) each year (Bhatet al. 2013). Symptoms of dengue fever include fever, headache, nausea, vomiting, and eye, muscle and joint pain (CDC). More sever manifestations such as abdominal pain, bleeding from nose and gums, vomiting of blood, and clammy skin occur in rare cases of dengue hemorrhagic fever (CDC). Dengue fever occurs throughout tropical and sub-tropical regions worldwide, however, the geographical range and size of epidemics is increasing. Weather and climate are drivers of dengue virus transmission dynamics (Morin et al. 2013) by affecting mosquito proliferation and the virus extrinsic incubation period (i.e. required time for the virus to replicate and disseminate within the mosquito before it can retransmit the virus).

    Full Text Available Case histories of 2 renal transplant recipients are reported who had presenting features of fever, leukocytosis and pain/tenderness over right iliac fossa and were diagnosed to be due to acute appendicitis rather than more commonly suspected acute rejection episode which has very similar features. Diagnosis of acute appendicitis was suspected on the basis of rectal examination and later confirmed by laparotomy. The purpose of this communication is to emphasize the need for proper diagnosis in patient with such presentation; otherwise wrong treatment may be received.

  6. Fever in the critically ill medical patient.

    Laupland, Kevin B

    2009-07-01

    Fever, commonly defined by a temperature of >or=38.3 degrees C (101 degrees F), occurs in approximately one half of patients admitted to intensive care units. Fever may be attributed to both infectious and noninfectious causes, and its development in critically ill adult medical patients is associated with an increased risk for death. Although it is widespread and clinically accepted practice to therapeutically lower temperature in patients with hyperthermic syndromes, patients with marked hyperpyrexia, and selected populations such as those with neurologic impairment, it is controversial whether most medical patients with moderate degrees of fever should be treated with antipyretic or direct cooling therapies. Although treatment of fever may improve patient comfort and reduce metabolic demand, fever is a normal adaptive response to infection and its suppression is potentially harmful. Clinical trials specifically comparing fever management strategies in neurologically intact critically ill medical patients are needed.

  7. Clinical features and patient management of Lujo hemorrhagic fever.

    Nivesh H Sewlall

    Full Text Available In 2008 a nosocomial outbreak of five cases of viral hemorrhagic fever due to a novel arenavirus, Lujo virus, occurred in Johannesburg, South Africa. Lujo virus is only the second pathogenic arenavirus, after Lassa virus, to be recognized in Africa and the first in over 40 years. Because of the remote, resource-poor, and often politically unstable regions where Lassa fever and other viral hemorrhagic fevers typically occur, there have been few opportunities to undertake in-depth study of their clinical manifestations, transmission dynamics, pathogenesis, or response to treatment options typically available in industrialized countries.We describe the clinical features of five cases of Lujo hemorrhagic fever and summarize their clinical management, as well as providing additional epidemiologic detail regarding the 2008 outbreak. Illness typically began with the abrupt onset of fever, malaise, headache, and myalgias followed successively by sore throat, chest pain, gastrointestinal symptoms, rash, minor hemorrhage, subconjunctival injection, and neck and facial swelling over the first week of illness. No major hemorrhage was noted. Neurological signs were sometimes seen in the late stages. Shock and multi-organ system failure, often with evidence of disseminated intravascular coagulopathy, ensued in the second week, with death in four of the five cases. Distinctive treatment components of the one surviving patient included rapid commencement of the antiviral drug ribavirin and administration of HMG-CoA reductase inhibitors (statins, N-acetylcysteine, and recombinant factor VIIa.Lujo virus causes a clinical syndrome remarkably similar to Lassa fever. Considering the high case-fatality and significant logistical impediments to controlled treatment efficacy trials for viral hemorrhagic fever, it is both logical and ethical to explore the use of the various compounds used in the treatment of the surviving case reported here in future outbreaks

    The results of CT in 100 patients with acute hemiplegia in childhood are reported here. The etiology was various: 2 patients had infratentorial brain tumors, 56 had cerebral vascular diseases, 3 had head injuries, 16 had intracranial infectious diseases, one had postinfectious encephalomyelitis, one had multiple sclerosis, 2 had epilepsy, and the diagnosis of 19 were unknown. Eleven patients had a normal CT and a good prognosis. As for the type of onset, there were patients of type 1 with fever and 42 with convulsions and unconsciousness; those of type 2 with convulsions and unconsciousness were 12, and those of type 3 without fever and convulsions were 46. This classification is assumed to be useful, as the type of onset is characteristic of the etiology. Six patients were diagnosed correctly by repeated examinations, although the first CT did not reveal any remarkable findings. Capsular infarction, occlusion of the posterior cerebral artery in acute hemiplegia in childhood, abnormal findings of the internal capsule, thalamus, and midbrain in a patient with postinfectious encephalomyelitis, and a diffuse low density in the CT of the unilateral hemisphere in the patients with acute encephalopathy and acute hemiplegia of an obscure origin have been found after the introduction of computerized tomography.

    Dengue fever (DF) is associated with significant morbidity and mortality in the tropical and sub-tropical regions of the world. Since there are no effective antiviral drugs for treatment, clinicians often rely on the accurate diagnosis of dengue fever to begin supportive therapy at early stages of the illness. The objective of this study was to develop an in-house dengue virus serotype 2 (DENV-2) non-structural protein- 5 (NS5) based indirect ELISA. DENV-2 was raised in Vero cells and the viral proteins were separated and subsequently the NS5 protein was eluted. Serum samples from primary and secondary dengue fever patients; and acute and convalescent samples from Japanese encephalitis (JE) and West Nile virus (WNV) cases were used to validate the ELISA. The assay was found to be 100 per cent specific in detecting DENV-2 specific antibodies from patient's serum. However, in terms of sensitivity, the assay could detect IgM antibodies only from 90 per cent of the primary dengue samples. The IgM/IgG ratio of the primary and secondary samples was 7.24 and 0.64, respectively. The results indicate that the DENV-2 NS5 ELISA is dengue group specific and can be used to differentiate dengue infection from other circulating Flavivirus infections. This NS5 ELISA can also be used to distinguish between primary and secondary dengue fever on the basis of IgM/IgG ratios. Further studies with larger sample sizes and different DENV serotypes are required to validate the ELISA.

    Full Text Available Crimean Congo hemorrhagic fever is a potentially fatal disease that is reported from Asia, Africa and Europe. In May, 2016 a 42 year-old female is admitted to Buali-Sina hospital with epistaxis and within a few hours got loss of consciousness and shock. The patient was put on supportive care and oral Ribavirin. From the sixth admission day, the general condition of the patient improved and on the eleventh day she was discharged without an important sequela. Consequently, it is necessary to consider this disease in the differential diagnosis of all patients presented with fever and acute bleeding diathesis.

    Rickettsia species are increasingly being recognized as a cause of infection among returning travelers. Murine typhus (MT) was mistakenly thought to have disappeared in the 1970s in Tunisia, yet recent serological data show that Rickettsia typhi, the causative agent of MT, still circulates in the Tunisian population. We report here a case of MT in a woman returning from Tunisia and hospitalized in France. Her presentation was nonspecific, with acute noneruptive fever. Diagnosis was confirmed by cross-adsorption and immunoblotting. Clinicians taking care of returning travelers with fever should be aware of MT, and know how to diagnose and treat it. © 2014 International Society of Travel Medicine.

    2015-01-01

    Background Ontologies represent powerful tools in information technology because they enhance interoperability and facilitate, among other things, the construction of optimized search engines. To address the need to expand the toolbox available for the control and prevention of vector-borne diseases we embarked on the construction of specific ontologies. We present here IDODEN, an ontology that describes dengue fever, one of the globally most important diseases that are transmitted by mosquitoes. Methodology/Principal Findings We constructed IDODEN using open source software, and modeled it on IDOMAL, the malaria ontology developed previously. IDODEN covers all aspects of dengue fever, such as disease biology, epidemiology and clinical features. Moreover, it covers all facets of dengue entomology. IDODEN, which is freely available, can now be used for the annotation of dengue-related data and, in addition to its use for modeling, it can be utilized for the construction of other dedicated IT tools such as decision support systems. Conclusions/Significance The availability of the dengue ontology will enable databases hosting dengue-associated data and decision-support systems for that disease to perform most efficiently and to link their own data to those stored in other independent repositories, in an architecture- and software-independent manner.

  16. Dengue fever and dengue haemorrhagic fever in adolescents and adults.

    Science.gov (United States)

    2012-05-01

    Dengue fever (DF) is endemic in tropical and subtropical zones and the prevalence is increasing across South-east Asia, Africa, the Western Pacific and the Americas. In recent years, the spread of unplanned urbanisation, with associated substandard housing, overcrowding and deterioration in water, sewage and waste management systems, has created ideal conditions for increased transmission of the dengue virus in tropical urban centres. While dengue infection has traditionally been considered a paediatric disease, the age distribution of dengue has been rising and more cases have been observed in adolescents and adults. Furthermore, the development of tourism in the tropics has led to an increase in the number of tourists who become infected, most of whom are adults. Symptoms and risk factors for dengue haemorrhagic fever (DHF) and severe dengue differ between children and adults, with co-morbidities and incidence in more elderly patients associated with greater risk of mortality. Treatment options for DF and DHF in adults, as for children, centre round fluid replacement (either orally or intravenously, depending on severity) and antipyretics. Further data are needed on the optimal treatment of adult patients.

    to describe acute brachial diplegia as the initial manifestation of Lyme disease. bilateral, predominantly motor, cervical radiculoplexus neuropathy, the "dangling arm syndrome," has not been reported as a complication of acute Lyme infection. retrospective series of 5 patients from 2 tertiary neuromuscular centers. there were 4 men and 1 woman with an average age of 69 years. One recalled a tick bite, and preceding constitutional symptoms included headache (2) and fever, arthralgias, and fatigue in 1 patient each. Proximal arm weakness and acute pain developed within 3 weeks from onset; pain was bilateral in 3 patients and unilateral in 2 patients, and was described as severe throbbing. Arm weakness was bilateral at onset in 3 patients, and right sided in 2 patients followed by spread to the left arm within days. All the patients had weakness in the deltoid and biceps that was 3/5 or less (Medical Research Council scale), with variable weakness of the triceps and wrist extensors; 1 patient had a flail right arm and moderate (4/5) weakness of the proximal left arm muscles. Light touch was normal in the regions of weakness, and 1 patient had mildly reduced pin sensation over the forearm. Serum IgM Lyme titers were elevated in all the patients and were detected in the cerebrospinal fluid in 4 tested patients. The cerebrospinal fluid protein ranged between 135 and 176 mg/dL with lymphocytic pleocytosis (range, 42 to 270 cells). Electrodiagnostic studies showed normal median and ulnar motor potentials with asymmetrically reduced sensory amplitudes in the median (4), ulnar (3), and radial, and lateral antebrachial cutaneous potentials in 1 patient each. Two patients had acute denervation in the cervical or proximal arm muscles. There was full recovery after antibiotic therapy in 4 patients and considerable improvement in 1 patient after 2 months. acute brachial diplegia is a rare manifestation of acute Lyme infection and responds promptly to antibiotic therapy.

To study this problem, we prospectively collected patients who developed fever after spine surgery during the academic year 2007-2008 for whom the internist's consultation was requested. Eighty-five (85) patients were identified, of which 17 had an identifiable infectious cause for their febrile reaction (20%) - fever was attributed to urinary tract infection in 8 cases, pneumonia in 5 cases, wound infection in 3 cases (all lumbar), and cholecystitis in 1 case. The remaining 68 patients (80%) had no definitive diagnosis and fever was attributed to a peripheral venous line which, in this case, was replaced or discontinued. In 32 (37.6%) of the patients, the fever developed on postoperative day (POD) 2 or later. There was no statistically significant relationship between day of fever appearance and whether the fever was due to definite infection (P = 0.737). Comparing the basic group with another group of 456 spine surgery patients from 2006-2007 who might or might not have developed fever postoperatively using ANOVA, we found a significant difference in age (P = 0.011) and a very significant difference in hemoglobin level (P = 0.000) and HbA1c level (P = 0.000), but not in body mass index (BMI) (P = 0.289). Thus, most of the postoperative fever cases after spine surgery have no identifiable infectious focus and develop mainly in older patients with anemia and inadequately controlled HbA1c. A meticulous investigation of the source of fever including laboratory and radiological studies remains essential. Early mobilization is recommended for individuals undergoing lower spine surgery in order to decrease bacterial contamination from the gluteal cleavage.
