An outbreak of acute febrile illness was reported among Somali pastoralists in remote, arid Northeast Kenya, where drinking raw milk is common. Blood specimens from 12 patients, collected mostly in the late convalescent phase, were tested for viral, bacterial, and parasitic pathogens. All were negative for viral and typhoid serology. Nine patients had Brucella antibodies present by at least one of the tests, four of whom had evidence suggestive of acute infection by the reference serologic microscopic agglutination test. Three patients were positive for leptospiral antibody by immunoglobulin M enzyme-linked immunosorbent assay, and two were positive for malaria. Although sensitive and specific point-of-care testing methods will improve diagnosis of acute febrile illness in developing countries, challenges of interpretation still remain when the outbreaks are remote, specimens collected too late, and positive results for multiple diseases are obtained. Better diagnostics and tools that can decipher overlapping signs and symptoms in such settings are needed.

Delays in seeking appropriate healthcare can increase the case fatality of acute febrile illnesses, and circuitous routes of care-seeking can have a catastrophic financial impact upon patients in low-income settings. To investigate the relationship between poverty and pre-hospital delays for patients with acute febrile illnesses, we recruited a cross-sectional, convenience sample of 527 acutely ill adults and children aged over 6 months, with a documented fever ≥38.0°C and symptoms of up to 14 days’ duration, presenting to a tertiary referral hospital in Chittagong, Bangladesh, over the course of one year from September 2011 to September 2012. Participants were classified according to the socioeconomic status of their households, defined by the Oxford Poverty and Human Development Initiative’s multidimensional poverty index (MPI). 51% of participants were classified as multidimensionally poor (MPI>0.33). Median time from onset of any symptoms to arrival at hospital was 22 hours longer for MPI poor adults compared to non-poor adults (123 vs. 101 hours) rising to a difference of 26 hours with adjustment in a multivariate regression model (95% confidence interval 7 to 46 hours; P = 0.009). There was no difference in delays for children from poor and non-poor households (97 vs. 119 hours; P = 0.394). Case fatality was 5.9% vs. 0.8% in poor and non-poor individuals respectively (P = 0.001)—5.1% vs. 0.0% for poor and non-poor adults (P = 0.010) and 6.4% vs. 1.8% for poor and non-poor children (P = 0.083). Deaths were attributed to central nervous system infection (11), malaria (3), urinary tract infection (2), gastrointestinal infection (1) and undifferentiated sepsis (1). Both poor and non-poor households relied predominantly upon the (often informal) private sector for medical advice before reaching the referral hospital, but MPI poor participants were less likely to have consulted a qualified doctor.

Background Despite the fact that a large proportion of children with fever in Africa present at primary health care facilities, few studies have been designed to specifically study the causes of uncomplicated childhood febrile illness at this level of care, especially in areas like Zanzibar that has recently undergone a dramatic change from high to low malaria transmission. Methods We prospectively studied the aetiology of febrile illness in 677 children aged 2–59 months with acute uncomplicated fever managed by IMCI (Integrated Management of Childhood Illness) guidelines in Zanzibar, using point-of-care tests, urine culture, blood-PCR, chest X-ray (CXR) of IMCI-pneumonia classified patients, and multiple quantitative (q)PCR investigations of nasopharyngeal (NPH) (all patients) and rectal (GE) swabs (diarrhoea patients). For comparison, we also performed NPH and GE qPCR analyses in 167 healthy community controls. Final fever diagnoses were retrospectively established based on all clinical and laboratory data. Clinical outcome was assessed during a 14-day follow-up. The utility of IMCI for identifying infections presumed to require antibiotics was evaluated. Findings NPH-qPCR and GE-qPCR detected ≥1 pathogen in 657/672 (98%) and 153/164 (93%) of patients and 158/166 (95%) and 144/165 (87%) of controls, respectively. Overall, 57% (387/677) had IMCI-pneumonia, but only 12% (42/342) had CXR-confirmed pneumonia. Two patients were positive for Plasmodium falciparum. Respiratory syncytial virus (24.5%), influenza A/B (22.3%), rhinovirus (10.5%) and group-A streptococci (6.4%), CXR-confirmed pneumonia (6.2%), Shigella (4.3%) were the most common viral and bacterial fever diagnoses, respectively. Blood-PCR conducted in a sub-group of patients (n = 83) without defined fever diagnosis was negative for rickettsiae, chikungunya, dengue, Rift Valley fever and West Nile viruses. Antibiotics were prescribed to 500 (74%) patients, but only 152 (22%) had an infection

Febrile Illness with Skin Rashes

PubMed Central

2015-01-01

Skin rashes that appear during febrile illnesses are in fact caused by various infectious diseases. Since infectious exanthematous diseases range from mild infections that disappear naturally to severe infectious diseases, focus on and basic knowledge of these diseases is very important. But, these include non-infectious diseases, so that comprehensive knowledge of these other diseases is required. Usually, early diagnostic testing for a febrile illness with a rash is inefficient. For clinical diagnosis of diseases accompanied by skin rash and fever, a complete history must be taken, including recent travel, contact with animals, medications, and exposure to forests and other natural environments. In addition, time of onset of symptoms and the characteristics of the rash itself (morphology, location, distribution) could be helpful in the clinical diagnosis. It is also critical to understand the patient's history of specific underlying diseases. However, diagnostic basic tests could be helpful in diagnosis if they are repeated and the clinical course is monitored. Generally, skin rashes are nonspecific and self-limited. Therefore, it could be clinically meaningful as a characteristic diagnostic finding in a very small subset of specific diseases. PMID:26483989

In 2009, an increased proportion of suspected dengue cases reported to the surveillance system in Puerto Rico were laboratory negative. As a result, enhanced acute febrile illness (AFI) surveillance was initiated in a tertiary care hospital. Patients with fever of unknown origin for 2–7 days duration were tested for Leptospira, enteroviruses, influenza, and dengue virus. Among the 284 enrolled patients, 31 dengue, 136 influenza, and 3 enterovirus cases were confirmed. Nearly half (48%) of the confirmed dengue cases met clinical criteria for influenza. Dengue patients were more likely than influenza patients to have hemorrhage (81% versus 26%), rash (39% versus 9%), and a positive tourniquet test (52% versus 18%). Mean platelet and white blood cell count were lower among dengue patients. Clinical diagnosis can be particularly difficult when outbreaks of other AFI occur during dengue season. A complete blood count and tourniquet test may be useful to differentiate dengue from other AFIs. PMID:23382160

Introduction Although malaria has been the leading cause of fever for many years, with improved control regimes malaria transmission, morbidity and mortality have decreased. Recent studies have increasingly demonstrated the importance of non-malaria fevers, which have significantly improved our understanding of etiologies of febrile illnesses. A number of non-malaria febrile illnesses including Rift Valley Fever, dengue fever, Chikungunya virus infection, leptospirosis, tick-borne relapsing fever and Q-fever have been reported in Tanzania. This study aimed at assessing the awareness of communities and practices of health workers on non-malaria febrile illnesses. Methods Twelve focus group discussions with members of communities and 14 in-depth interviews with health workers were conducted in Kilosa district, Tanzania. Transcripts were coded into different groups using MaxQDA software and analyzed through thematic content analysis. Results The study revealed that the awareness of the study participants on non-malaria febrile illnesses was low and many community members believed that most instances of fever are due to malaria. In addition, the majority had inappropriate beliefs about the possible causes of fever. In most cases, non-malaria febrile illnesses were considered following a negative Malaria Rapid Diagnostic Test (mRDT) result or persistent fevers after completion of anti-malaria dosage. Therefore, in the absence of mRDTs, there is over diagnosis of malaria and under diagnosis of non-malaria illnesses. Shortages of diagnostic facilities for febrile illnesses including mRDTs were repeatedly reported as a major barrier to proper diagnosis and treatment of febrile patients. Conclusion Our results emphasize the need for creating community awareness on other causes of fever apart from malaria. Based on our study, appropriate treatment of febrile patients will require inputs geared towards strengthening of diagnostic facilities, drugs availability and optimal

Serum specimens from 114 patients hospitalized with a febrile illness were tested with an indirect immunofluorescence assay (IFA) using Bartonella antigens prepared from 6 species of sigmodontine rodents and 3 known human Bartonella pathogens: B. henselae, B. quintana, and B. elizabethae. Acute- and convalescent-phase serum samples from 5 of these patients showed seroconversion with an IFA titer >512 to rodent-associated Bartonella antigens. The highest titer was against antigen derived from the white-throated woodrat (Neotoma albigula), although this rodent is not necessarily implicated as the source of infection. Three of the 5 who seroconverted showed no cross-reaction to the 3 Bartonella human pathogens. Common clinical characteristics were fever, chills, myalgias, leukopenia, thrombocytopenia, and transaminasemia. Although antibodies to Bartonella are cross-reactive, high-titer seroconversions to rodent-associated Bartonella antigens in adults with common clinical characteristics should stimulate the search for additional Bartonella human pathogens.

Dengue often presents with non-specific clinical signs, and given the current paucity of accurate, rapid diagnostic laboratory tests, identifying easily obtainable bedside markers of dengue remains a priority. Previous studies in febrile Asian children have suggested that the combination of a positive tourniquet test (TT) and leucopenia can distinguish dengue from other febrile illnesses, but little data exists on the usefulness of these tests in adults or in the Americas. We evaluated the diagnostic accuracy of the TT and leucopenia (white blood cell count <5000/mm3) in identifying dengue as part of an acute febrile illness (AFI) surveillance study conducted in the Emergency Department of Saint Luke's Hospital in Ponce, Puerto Rico. From September to December 2009, 284 patients presenting to the ED with fever for 2–7 days and no identified source were enrolled. Participants were tested for influenza, dengue, leptospirosis and enteroviruses. Thirty-three (12%) patients were confirmed as having dengue; 2 had dengue co-infection with influenza and leptospirosis, respectively. An infectious etiology was determined for 141 others (136 influenza, 3 enterovirus, 2 urinary tract infections), and 110 patients had no infectious etiology identified. Fifty-two percent of laboratory-positive dengue cases had a positive TT versus 18% of patients without dengue (P<0.001), 87% of dengue cases compared to 28% of non-dengue cases had leucopenia (P<0.001). The presence of either a positive TT or leucopenia correctly identified 94% of dengue patients. The specificity and positive predictive values of these tests was significantly higher in the subset of patients without pandemic influenza A H1N1, suggesting improved discriminatory performance of these tests in the absence of concurrent dengue and influenza outbreaks. However, even during simultaneous AFI outbreaks, the absence of leucopenia combined with a negative tourniquet test may be useful to rule out dengue. PMID:22163057

Febrile infection-related epilepsy syndrome (FIRES) is a devastating epilepsy affecting normal children after a febrile illness. FIRES presents with an acute phase with super-refractory status epilepticus and all patients progress to a chronic phase with persistent refractory epilepsy. The typical outcome is severe encephalopathy or death. The authors present 7 children from 5 centers with FIRES who had not responded to antiepileptic drugs or other therapies who were given cannabadiol (Epidiolex, GW Pharma) on emergency or expanded investigational protocols in either the acute or chronic phase of illness. After starting cannabidiol, 6 of 7 patients' seizures improved in frequency and duration. One patient died due to multiorgan failure secondary to isoflourane. An average of 4 antiepileptic drugs were weaned. Currently 5 subjects are ambulatory, 1 walks with assistance, and 4 are verbal. While this is an open-label case series, the authors add cannabidiol as a possible treatment for FIRES.

Because the prevalence of dengue fever in urban settings in Papua New Guinea is unknown, we investigated the presence of dengue using the NS1 antigen test in an outpatient-based prospective observational study at Port Moresby General Hospital. Of 140 patients with acute febrile illnesses, dengue fever was diagnosed in 14.9% (20 of 134; 95% confidence interval [95% CI] = 9.6-22.4). Malaria (2 of 137; 1.5%; 95% CI = 0.3-5.7), chikungunya (3 of 140; 2.1%; 95% CI = 0.6-6.6), and bacterial bloodstream infections (0 of 80; 0%; 95% CI = 0-5.7) were uncommon. Dengue fever should no longer be considered rare in Papua New Guinea. © The American Society of Tropical Medicine and Hygiene.

We describe the management of a 4-year-old child with acute lymphoblastic leukaemia (ALL) who presented with febrile neutropenia, Cryptosporidium and subsequently developed refeeding syndrome. Febrile neutropenia is common and can be life-threatening and we highlight the identification of well low-risk neutropenic children with resolved febrile illnesses suitable for early discharge. We also discuss the potential management strategies for Cryptosporidium Refeeding syndrome is not common, but should be considered as a cause of acute inpatient deterioration and is a significant risk, with potential morbidity, in children who have undergone a period of catabolism.

Antibiotic resistance mechanisms originating in low- and middle- income countries are among the most common worldwide. Reducing unnecessary antibiotic use in India, the world's largest antibiotic consumer, is crucial to control antimicrobial resistance globally. Limited data describing factors influencing Indian clinicians to start or stop antibiotics are available. Febrile adults and children admitted to a public tertiary care hospital in Pune, India, were enrolled. Antibiotic usage and clinical history were recorded. Immunoassays for mosquito-borne disease and bacterial cultures were performed by protocol and clinician-directed testing. Clinical factors were assessed for association with empiric antibiotic initiation and discontinuation by day 5 using multivariable logistic regression and propensity score-matched Cox proportional hazard models. Among 1486 participants, 683 (82%) adults and 614 (94%) children received empiric antibiotics. Participants suspected of having mosquito-borne disease were less likely to receive empiric antibiotics (adjusted odds ratio [AOR], 0.5; 95% confidence interval [CI], .4-.8). Empiric antibiotics were discontinued in 450 (35%) participants by day 5. Dengue or malaria testing performed before day 4 was positive in 162 (12%) participants, and was associated with antibiotic discontinuation (AOR, 1.7; 95% CI, 1.2-2.4). In a propensity score-matched model accounting for admission suspicion of mosquito-borne disease, positive dengue or malaria tests increased hazard of antibiotic discontinuation (hazard ratio, 1.6; 95% CI, 1.2-2.0). Most patients with acute febrile illness in an Indian public hospital setting receive empiric antibiotics. Mosquito-borne disease identification is associated with reduced empiric antibiotic use and faster antibiotic discontinuation.

Abstract Background Acute febrile illness is a common reason for hospitalization in many developing countries, including Indonesia. While patients can often be categorized and managed based on clinical presentations, diagnostic capacity in these countries remains limited, leading to poor patient outcomes. For patients with central nervous system (CNS) infections, identifying the underlying etiologies is particularly important to prevent lifelong neurological complications and death. Methods As part of a study conducted at 8 top-referral hospitals across Indonesia from 2013 to 2016, 114 of 1,486 enrolled subjects presented with an acute fever and a CNS syndrome. To identify the etiologies and clinical manifestations of these infections, as well as the management of febrile patients at the hospitals, demographic and clinical data were collected at enrollment, and blood samples were collected for diagnostic testing at enrollment, once during days 14–28, and at 3 months after enrollment. Results Subject ages ranged from 1 to 63.2 years old (median of 4.9 years old), and underlying diseases were reported in 35 (30.7%) subjects. Standard-of-care, molecular, and serological testing identified pathogens in 56 (49.1%) cases, as detailed in the table. Of the 19 subjects who died, 18 presented with decreased consciousness and 5 were infected with Rickettsia typhi, which was clinically misdiagnosed in each case. Conclusion The findings from this study will improve the diagnosis and treatment of patients presenting with CNS syndromes in Indonesia. Additionally, the discovery of misdiagnosed, fatal etiologies highlights the general need for greater diagnostic testing capacity to aid clinicians and inform public health policy makers.

Sierra Leone in West Africa is in a Lassa fever–hyperendemic region that also includes Guinea and Liberia. Each year, suspected Lassa fever cases result in submission of ≈500–700 samples to the Kenema Government Hospital Lassa Diagnostic Laboratory in eastern Sierra Leone. Generally only 30%–40% of samples tested are positive for Lassa virus (LASV) antigen and/or LASV-specific IgM; thus, 60%–70% of these patients have acute diseases of unknown origin. To investigate what other arthropod-borne and hemorrhagic fever viral diseases might cause serious illness in this region and mimic Lassa fever, we tested patient serum samples that were negative for malaria parasites and LASV. Using IgM-capture ELISAs, we evaluated samples for antibodies to arthropod-borne and other hemorrhagic fever viruses. Approximately 25% of LASV-negative patients had IgM to dengue, West Nile, yellow fever, Rift Valley fever, chikungunya, Ebola, and Marburg viruses but not to Crimean-Congo hemorrhagic fever virus.

Q fever is an endemic disease in different parts of Iran. This study aimed to investigate the prevalence of acute Q fever disease among at-risk individuals in northwestern Iran. An etiological study was carried out in 2013 in Tabriz County. A total of 116 individuals who were in contact with livestock and had a nonspecific febrile illness were enrolled in the study. IgG phase II antibodies against Coxiella burnetii were detected using ELISA. The prevalence of acute Q fever was 13.8% (95% confidence interval [CI]: 8.0, 21.0%). Headache (87.5%) and fatigue and weakness (81.3%) were the dominant clinical characteristics among patients whit acute Q fever. Acute lower respiratory tract infection and chills were poorly associated with acute Q fever. Furthermore, 32% (95% CI: 24, 41%) of participants had a history of previous exposure to Q fever agent (past infection). Consumption of unpasteurized dairy products was a weak risk factor for previous exposure to C. burnetii. This study identified patients with acute Q fever in northwestern of Iran. The evidence from this study and previous studies conducted in different regions of Iran support this fact that Q fever is one of the important endemic zoonotic diseases in Iran and needs due attention by clinical physicians and health care system.

Aim: An important life-threatening complication of intensive chemotherapy administered in children with leukemia is febrile neutropenia. The objective of this study was to evaluate the clinical features and consequences of febrile neutropenia attacks in children who were treated for acute lymphoblastic leukemia. Material and Methods: Nighty-six children who received chemotherapy for acute lymphoblastic leukemia in our center between January 1995 and December 2010 were included in the study. The data related to demographic characteristics, treatment features, relapse and febrile neutropenia incidences, risk factors, culture results and prognosis were retrospectively evaluated from the patients’ files. Results: A total of two hundred-ninety nine febrile neutropenia attacks observed in the patients during initial treatment and relapse treatment were evaluated. When the incidence of febrile neutropenia was evaluated by years, it was observed that the patients treated after year 2000 had statistically significantly more febrile neutopenia attacks compared to the patients treated before year 2000. When the incidences of febrile neutropenia during initial treatment and during relapse treatment were compared, it was observed that more febrile neutropenia attacks occured during relapse treatment. Fifty-nine percent of all febrile neutropenia attacks were fever of unknown origin. Eighty microorganisms grew in cultures during febrile neutropenia throughout treatment in 75 patients; 86% were bacterial infections (50% gram positive and 50% gram negative), 8% were viral infections and 6% were fungal infections. Coagulase negative staphylococcus (n=17) was the most frequent gram positive pathogen; E. Coli (n=17) was the most commonly grown gram negative pathogen. Conclusions: In this study, it was found that an increase in the incidence of febrile neutropenia occured in years. Increments in treatment intensities increase the incidence of febrile neutropenia while improving

A single diagnostic test for acute undifferentiated febrile illnesses (AUFI) is elusive. This pilot study was undertaken on the premise that leucocytes, being the main cells of defence, undergo quantitative, structural and functional changes in AUFI. We evaluated the potential of volume, conductivity and scatter (VCS) parameters of leucocytes, generated with the haemogram report by the Coulter auto-analyzer, in differentiating the common etiologies of AUFI. The haematological and VCS data obtained from 800 controls and 200 cases of AUFI (50 cases each of acute malaria, dengue, scrub typhus and enteric fever) were retrieved for analysis. The cases and controls differed significantly with respect to relative numbers and the VCS parameters of neutrophils, lymphocytes and monocytes (p<0.05). The neutrophil and lymphocyte were significantly voluminous in acute malaria and scrub typhus as compared to dengue and enteric fevers (p<0.05). Enteric fever significantly enhanced the conductivity of neutrophils as compared to other subgroups while lymphocyte conductivity significantly differed from dengue and scrub typhus. Lymphocyte and neutrophil scatter values in malaria and scrub typhus were comparable but differed significantly from that in enteric fever. Etiology-specific changes occur in leucocytes, both in numbers and their VCS properties which can be identified without additional cost. © The Author 2016.

Understanding the epidemiology of current health threats to deployed U.S. troops is important for medical assessment and planning. As part of a 2004 study among U.S. military personnel deployed to Al Asad Air Base, in the western Anbar Province of Iraq, over 500 subjects were enrolled, provided a blood specimen, and completed a questionnaire regarding history of febrile illness during this deployment (average approximately 4 months in country). This mid-deployment serum was compared to pre-deployment samples (collected approximately 3 months prior to deployment) and evaluated for seroconversion to a select panel of regional arboviral pathogens. At least one episode of febrile illness was reported in 84/504 (17%) of the troops surveyed. Seroconversion was documented in nine (2%) of deployed forces tested, with no association to febrile illness. Self-reported febrile illness was uncommon although often debilitating, and the risk of illness due to arbovirus infections was relatively low.

Background Q fever is an endemic disease in different parts of Iran. This study aimed to investigate the prevalence of acute Q fever disease among at-risk individuals in northwestern Iran. Methodology An etiological study was carried out in 2013 in Tabriz County. A total of 116 individuals who were in contact with livestock and had a nonspecific febrile illness were enrolled in the study. IgG phase II antibodies against Coxiella burnetii were detected using ELISA. Principal findings The prevalence of acute Q fever was 13.8% (95% confidence interval [CI]: 8.0, 21.0%). Headache (87.5%) and fatigue and weakness (81.3%) were the dominant clinical characteristics among patients whit acute Q fever. Acute lower respiratory tract infection and chills were poorly associated with acute Q fever. Furthermore, 32% (95% CI: 24, 41%) of participants had a history of previous exposure to Q fever agent (past infection). Consumption of unpasteurized dairy products was a weak risk factor for previous exposure to C. burnetii. Conclusion This study identified patients with acute Q fever in northwestern of Iran. The evidence from this study and previous studies conducted in different regions of Iran support this fact that Q fever is one of the important endemic zoonotic diseases in Iran and needs due attention by clinical physicians and health care system.

Background With apparent declines in malaria worldwide during the last decade and more widespread use of malaria rapid diagnostic tests, healthcare workers in low-resource areas face a growing proportion of febrile patients without malaria. We sought to describe current knowledge and identify information gaps of the etiology severe febrile illness in low-and middle-income countries. Methods and Findings We conducted a systematic review of studies conducted in low-and-middle income countries 1980–2013 that prospectively assessed consecutive febrile patients admitted to hospital using rigorous laboratory-based case definitions. We found 45 eligible studies describing 54,578 patients; 9,771 (17.9%) had a positive result for ≥1 pathogen meeting diagnostic criteria. There were no eligible studies identified from Southern and Middle Africa, Eastern Asia, Oceania, Latin American and Caribbean regions, and the European region. The median (range) number of diagnostic tests meeting our confirmed laboratory case definitions was 2 (1 to 11) per study. Of diagnostic tests, 5,052 (10.3%) of 49,143 had confirmed bacterial or fungal bloodstream infection; 709 (3.8%) of 18,142 had bacterial zoonosis; 3,488 (28.5%) of 12,245 had malaria; and 1,804 (17.4%) of 10,389 had a viral infection. Conclusions We demonstrate a wide range of pathogens associated with severe febrile illness and highlight the substantial information gaps regarding the geographic distribution and role of common pathogens. High quality severe febrile illness etiology research that is comprehensive with respect to pathogens and geographically representative is needed. PMID:26126200

2013-10-01

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.

2014-02-01

Tropical febrile illnesses such as malaria and dengue are challenging to differentiate clinically. Automated cellular indices from hematology analyzers may afford a preliminary rapid distinction. Blood count and VCS parameters from 114 malaria patients, 105 dengue patients, and 105 febrile controls without dengue or malaria were analyzed. Statistical discriminant functions were generated, and their diagnostic performances were assessed by ROC curve analysis. Three statistical functions were generated: (i) malaria-vs.-controls factor incorporating platelet count and standard deviations of lymphocyte volume and conductivity that identified malaria with 90.4% sensitivity, 88.6% specificity; (ii) dengue-vs.-controls factor incorporating platelet count, lymphocyte percentage and standard deviation of lymphocyte conductivity that identified dengue with 81.0% sensitivity and 77.1% specificity; and (iii) febrile-controls-vs.-malaria/dengue factor incorporating mean corpuscular hemoglobin concentration, neutrophil percentage, mean lymphocyte and monocyte volumes, and standard deviation of monocyte volume that distinguished malaria and dengue from other febrile illnesses with 85.1% sensitivity and 91.4% specificity. Leukocyte abnormalities quantitated by automated analyzers successfully identified malaria and dengue and distinguished them from other fevers. These economic discriminant functions can be rapidly calculated by analyzer software programs to generate electronic flags to trigger-specific testing. They could potentially transform diagnostic approaches to tropical febrile illnesses in cost-constrained settings. © 2013 John Wiley & Sons Ltd.

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. © The American Society of Tropical Medicine and Hygiene.

We conducted a yearlong prospective study of febrile patients admitted to a tertiary referral hospital in Chittagong, Bangladesh, to assess the proportion of patients with rickettsial illnesses and identify the causative pathogens, strain genotypes, and associated seasonality patterns. We diagnosed scrub typhus in 16.8% (70/416) and murine typhus in 5.8% (24/416) of patients; 2 patients had infections attributable to undifferentiated Rickettsia spp. and 2 had DNA sequence–confirmed R. felis infection. Orientia tsutsugamushi genotypes included Karp, Gilliam, Kato, and TA763-like strains, with a prominence of Karp-like strains. Scrub typhus admissions peaked in a biphasic pattern before and after the rainy season, whereas murine typhus more frequently occurred before the rainy season. Death occurred in 4% (18/416) of cases; case-fatality rates were 4% each for scrub typhus (3/70) and murine typhus (1/28). Overall, 23.1% (96/416) of patients had evidence of treatable rickettsial illnesses, providing important evidence toward optimizing empirical treatment strategies. PMID:29553921

Identifying etiologies of acute febrile illnesses (AFI) is challenging due to non-specific presentation and limited availability of diagnostics. Prospective AFI studies provide a methodology to describe the syndrome by age and etiology, findings that can be used to develop case definitions and multiplexed diagnostics to optimize management. We conducted a 3-year prospective AFI study in Puerto Rico. Patients with fever ≤7 days were offered enrollment, and clinical data and specimens were collected at enrollment and upon discharge or follow-up. Blood and oro-nasopharyngeal specimens were tested by RT-PCR and immunodiagnostic methods for infection with dengue viruses (DENV) 1-4, chikungunya virus (CHIKV), influenza A and B viruses (FLU A/B), 12 other respiratory viruses (ORV), enterovirus, Leptospira spp., and Burkholderia pseudomallei. Clinical presentation and laboratory findings of participants infected with DENV were compared to those infected with CHIKV, FLU A/B, and ORV. Clinical predictors of laboratory-positive dengue compared to all other AFI etiologies were determined by age and day post-illness onset (DPO) at presentation. Of 8,996 participants enrolled from May 7, 2012 through May 6, 2015, more than half (54.8%, 4,930) had a pathogen detected. Pathogens most frequently detected were CHIKV (1,635, 18.2%), FLU A/B (1,074, 11.9%), DENV 1-4 (970, 10.8%), and ORV (904, 10.3%). Participants with DENV infection presented later and a higher proportion were hospitalized than those with other diagnoses (46.7% versus 27.3% with ORV, 18.8% with FLU A/B, and 11.2% with CHIKV). Predictors of dengue in participants presenting <3 DPO included leukopenia, thrombocytopenia, headache, eye pain, nausea, and dizziness, while negative predictors were irritability and rhinorrhea. Predictors of dengue in participants presenting 3-5 DPO were leukopenia, thrombocytopenia, facial/neck erythema, nausea, eye pain, signs of poor circulation, and diarrhea; presence of rhinorrhea

The ethnographic study was conducted in two communities in Oyo State in Southwestern Nigeria. The study sites consisted of a rural and an urban local government area located in the tropical rain forest zone of Nigeria. The study was designed to obtain information on febrile illnesses and herbal remedies for treatment with the aim of identifying potential antimalarial drugs. The study revealed that fever is a general term for describing illnesses associated with elevated body temperature. The indigenous Yoruba ethnic population has categorized fever based on symptoms and causes. The present communication is the result of focus group discussion and semi-structured questionnaire administered to traditional healers, herb sellers, elders and mothers. This was on types of fevers, symptoms and causes of febrile illnesses. The investigation also included use of traditional herbs in the prevention and treatment of the illnesses in the two communities.A total of 514 respondents were interviewed. This was made up of 266 (51.8%) from Atiba local government area (LGA), an urban centre while 248 (48.2%) respondents were interviewed from Itesiwaju LGA, a rural community. The LGAs are located in Oyo State of Nigeria. The respondents proffered 12 types of febrile illnesses in a multiple response answering system in Yoruba language. The most common ones (direct translation into English) were: yellow fever (39.1%), typhoid (34.8%), ordinary (28.8%), rainy season (20.8%) and headache (10.5%) fevers, respectively. Perceived causes of each of the febrile illnesses included stress, mosquito bites, unclean water, rains and over exposure to the sun. Methods of fever prevention were mainly with the use of herbal decoctions, powdered herbs, orthodox medications and maintenance of proper hygiene. Of a total of 112 different herbal remedies used in the treatment of the febrile illnesses compiled from the study, 25 recipes are presented. Recipes consisted of 2-7 ingredients.

Febrile proteinuria is functional proteinuria and is seen as a transitory phenomenon during acute febrile illness, mainly viral infections. It is a benign phenomenon and clears promptly with resolution of the infection. In this report, we present a patient who was thought to have febrile proteinuria. Persistence of significant proteinuria after resolution of the infection prompted biochemical and genetic work-up which lead to the diagnosis of Dent-2 disease. We recommend the use of sodium dodecyl sulphate electropheresis (SDS-PAGE) for the detection of low molecular weight proteinuria. ©2018The Author(s). Published by S. Karger AG, Basel.

Childhood febrile illness and the risk of myopia in UK Biobank participants.

Historical reports suggest febrile illness during childhood is a risk factor for myopia. The establishment of the UK Biobank provided a unique opportunity to investigate this relationship. We studied a sample of UK Biobank participants of White ethnicity aged 40-69 years old who underwent autorefraction (N=91 592) and were classified as myopic (≤-0.75 Dioptres (D)), highly myopic (≤-6.00 D), or non-myopic (>-0.75 D). Self-reported age at diagnosis of past medical conditions was ascertained during an interview with a nurse at a Biobank assessment centre. Logistic regression analysis was used to calculate the odds ratio (OR) for myopia or high myopia associated with a diagnosis before age 17 years of each of nine febrile illnesses, after adjusting for potential confounders (age, sex, highest educational qualification, and birth order). Rubella, mumps, and pertussis were associated with myopia: rubella, OR=1.38, 95% CI: 1.03-1.85, P=0.030; mumps, OR=1.32, 95% CI: 1.07-1.64, P=0.010; and pertussis, OR=1.39, 95% CI 1.03-1.87, P=0.029. Measles, rubella, and pertussis were associated with high myopia: measles, OR=1.48, 95% CI: 1.07-2.07, P=0.019; rubella, OR=1.94, 95% CI: 1.12-3.35, P=0.017; and pertussis, OR=2.15, 95% CI: 1.24-3.71, P=0.006. The evidence did not support an interaction between education and febrile illness in explaining the above risks. A history of childhood measles, rubella, or pertussis was associated with high myopia, whereas a history of childhood rubella, mumps, or pertussis was associated with any myopia. The reasons for these associations are unclear.

Leptospirosis is often mistaken for other acute febrile illnesses because of its nonspecific presentation. Bacteriologic, serologic, and molecular methods have several limitations for early diagnosis: technical complexity, low availability, low sensitivity in early disease, or high cost. This study aimed to validate a case definition, based on simple clinical and laboratory tests, that is intended for bedside diagnosis of leptospirosis among hospitalized patients. Adult patients, admitted to two reference hospitals in Recife, Brazil, with a febrile illness of less than 21 days and with a clinical suspicion of leptospirosis, were included to test a case definition comprising ten clinical and laboratory criteria. Leptospirosis was confirmed or excluded by a composite reference standard (microscopic agglutination test, ELISA, and blood culture). Test properties were determined for each cutoff number of the criteria from the case definition. Ninety seven patients were included; 75 had confirmed leptospirosis and 22 did not. Mean number of criteria from the case definition that were fulfilled was 7.8±1.2 for confirmed leptospirosis and 5.9±1.5 for non-leptospirosis patients (p<0.0001). Best sensitivity (85.3%) and specificity (68.2%) combination was found with a cutoff of 7 or more criteria, reaching positive and negative predictive values of 90.1% and 57.7%, respectively; accuracy was 81.4%. The case definition, for a cutoff of at least 7 criteria, reached average sensitivity and specificity, but with a high positive predictive value. Its simplicity and low cost make it useful for rapid bedside leptospirosis diagnosis in Brazilian hospitalized patients with acute severe febrile disease.

Acute diarrheal illness during deployment causes significant morbidity and loss of duty days. Effective and timely treatment is needed to reduce individual, unit, and health system performance impacts. This critical appraisal of the literature, as part of the development of expert consensus guidelines, asked several key questions related to self-care and healthcare-seeking behavior, antibiotics for self-treatment of travelers' diarrhea, what antibiotics/regimens should be considered for treatment of acute watery diarrhea and febrile diarrhea and/or dysentery, and when and what laboratory diagnostics should be used to support management of deployment-related travelers' diarrhea. Studies of acute diarrhea management in military and other travelers were assessed for relevance and quality. On the basis of this critical appraisal, guideline recommendations were developed and graded by the Expert Panel using good standards in clinical guideline development methodology. New definitions for defining the severity of diarrhea during deployment were established. A total of 13 graded recommendations on the topics of prophylaxis, therapy and diagnosis, and follow-up were developed. In addition, four non-graded consensus-based statements were adopted. Successful management of acute diarrheal illness during deployment requires action at the provider, population, and commander levels. Strong evidence supports that single-dose antimicrobial therapy is effective in most cases of moderate to severe acute diarrheal illness during deployment. Further studies are needed to address gaps in available knowledge regarding optimal therapies for treatment, prevention, and laboratory testing of acute diarrheal illness.

In sub-Saharan Africa, malaria is frequently overdiagnosed as the cause of an undifferentiated febrile illness, whereas arboviral illnesses are presumed to be underdiagnosed. Sera from 385 febrile Kenyan children, who presented to 1 of 4 clinical sites, were tested using microscopy and real-time molecular assays for dengue virus (DENV), chikungunya virus (CHIKV), malaria, and Leptospira . Malaria was the primary clinical diagnosis for 254 patients, and an arboviral infection (DENV or CHIKV) was the primary diagnosis for 93 patients. In total, 158 patients (41.0%) had malaria and 32 patients (8.3%) had CHIKV infections. Compared with real-time polymerase chain reaction, microscopy demonstrated a percent positive agreement of 49.7%. The percentage of malaria cases detected by microscopy varied significantly between clinical sites. Arboviral infections were the clinical diagnosis for patients on the Indian Ocean coast (91 of 238, 38.2%) significantly more often than patients in the Lake Victoria region (2 of 145, 1.4%; P < .001). However, detection of CHIKV infections was significantly higher in the Lake Victoria region (19 of 145 [13.1%] vs 13 of 239 [5.4%]; P = .012). The clinical diagnosis of patients with an acute febrile illness, even when aided by microscopy, remains inaccurate in malaria-endemic areas, contributing to inappropriate management decisions.

Consecutive febrile admissions were enrolled at two hospitals in Moshi, Tanzania. Confirmed acute Chikungunya virus (CHIKV), Dengue virus (DENV), and flavivirus infection were defined as a positive polymerase chain reaction (PCR) result. Presumptive acute DENV infection was defined as a positive anti-DENV immunoglobulin M (IgM) enzyme-linked immunsorbent assay (ELISA) result, and prior flavivirus exposure was defined as a positive anti-DENV IgG ELISA result. Among 870 participants, PCR testing was performed on 700 (80.5%). Of these, 55 (7.9%) had confirmed acute CHIKV infection, whereas no participants had confirmed acute DENV or flavivirus infection. Anti-DENV IgM serologic testing was performed for 747 (85.9%) participants, and of these 71 (9.5%) had presumptive acute DENV infection. Anti-DENV IgG serologic testing was performed for 751 (86.3%) participants, and of these 80 (10.7%) had prior flavivirus exposure. CHIKV infection was more common among infants and children than adults and adolescents (odds ratio [OR] 1.9, P = 0.026) and among HIV-infected patients with severe immunosuppression (OR 10.5, P = 0.007). CHIKV infection is an important but unrecognized cause of febrile illness in northern Tanzania. DENV or other closely related flaviviruses are likely also circulating.

Abstract Background Infectious diseases remain a significant healthcare burden in the developing world. In Indonesia, clinicians often manage and treat patients solely based on clinical presentations since the diagnostic testing capacities of hospitals are limited. Unfortunately, the most common infections in this tropical environment share highly similar manifestations, complicating the identification of etiologies and leading to the misdiagnosis of illness. When pathogen-specific testing is available, generally at top-tier specialist hospitals, the limited range of tests and slow turnaround times may never lead to a definitive diagnosis or improved patient outcomes. Methods To identify clinical parameters that can be used for differentiating the most common causes of fever in Indonesia, we evaluated clinical data from 1,486 acute febrile patients enrolled in a multi-site observational cohort study during 2013 to 2016. Results From the 66% of subjects with confirmed etiologies, the six most common infections were dengue virus (455), Salmonella spp. (124), Rickettsia spp. (109), influenza virus (64), Leptospira spp. (53), and chikungunya virus (37). The accompanying figure shows the clinical signs and symptoms (A) and hematology and blood chemistry results (B) for the color-coded pathogens. Comparing the profiles of all infected subjects reveals parameters that are uniquely associated with particular pathogens, such as leukopenia with dengue virus. Conclusion These observations will assist clinicians in healthcare systems with limited diagnostic testing capacities and may be useful in formulating diagnostic algorithms for Indonesia and other developing countries.

Treatment of acute lymphoblastic leukaemia (ALL) using intensive chemotherapy has resulted in high cure rates but also substantial morbidity. Infective complications represent a significant proportion of treatment-related toxicity. The objective of this study was to describe the microbiological aetiology and clinical outcome of episodes of chemotherapy-induced febrile neutropaenia in a cohort of children treated for ALL at our institution. Patients with ALL were treated with either the HKSGALL93 or the Malaysia-Singapore (Ma-Spore) 2003 chemotherapy protocols. The records of 197 patients who completed the intensive phase of treatment, defined as the period of treatment from induction, central nervous system (CNS)-directed therapy to reinduction from June 2000 to January 2010 were retrospectively reviewed. There were a total of 587 episodes of febrile neutropaenia in 197 patients, translating to an overall rate of 2.98 episodes per patient. A causative pathogen was isolated in 22.7% of episodes. An equal proportion of Gram-positive bacteria (36.4%) and Gram-negative bacteria (36.4%) were most frequently isolated followed by viral pathogens (17.4%), fungal pathogens (8.4%) and other bacteria (1.2%). Fungal organisms accounted for a higher proportion of clinically severe episodes of febrile neutropaenia requiring admission to the high-dependency or intensive care unit (23.1%). The overall mortality rate from all episodes was 1.5%. Febrile neutropaenia continues to be of concern in ALL patients undergoing intensive chemotherapy. The majority of episodes will not have an identifiable causative organism. Gram-positive bacteria and Gram-negative bacteria were the most common causative pathogens identified. With appropriate antimicrobial therapy and supportive management, the overall risk of mortality from febrile neutropaenia is extremely low.

The current roll-out of rapid diagnostic tests (RDTs) in many endemic countries has resulted in the reporting of fewer cases of malaria-attributed illnesses. However, lack of knowledge of the prevalence of other febrile illnesses and affordable diagnostic tests means that febrile patients are not managed optimally. This study assessed the prevalence of commonly treatable or preventable febrile illnesses in children between 6 months and 15 years using rapid diagnostic tests at the point-of-care. Febrile children were enrolled between February-April 2014 at a health facility after obtaining informed consent from parent. Eligible participants were aged 6 months-15 years with a history of fever in the last 24 h or axillary temperature ≥38 °C at consultation. All participants were tested using RDTs for malaria, typhoid, toxoplasmosis and rubella. Malaria parasites were further identified by microscopy and PCR. Clinical and household characteristics were recorded and association with pathogens determined. Of the 315 children enrolled, the mean age was 5.8 ± 3.8 years. Stomach pain (41.2 %) was the most reported symptom. Prior to attending the health facility, 70.8 % had taken antipyretics, 27.9 % antimalarials, 11.4 % antibiotics and 13.3 % antifungal drugs. Among 315 children with fever, based on RDTs, 56.8 % were infected with malaria, 4.4 % with typhoid, 3.2 % with acute toxoplasmosis, and 1.3 % with rubella (all positive for rubella were in the same family and not vaccinated). All non-malarial infections were co-infections and approximately 30 % of the fever cases went un-diagnosed. Malaria prevalence by microscopy and PCR was 43.4 and 70.2 % respectively. The sensitivity and specificity of RDTs for the diagnosis of malaria were 75.98 and 100 % respectively, with 0.73 measurement agreement between RDTs and microscopy while that of RDT and PCR were 81 and 100 % respectively with a K value of 0.72.

Public health facilities are usually the first to receive interventions compared to private facilities, yet majority of health seeking care is first done with the latter. This study compared the capacity to manage acute febrile illnesses in children below 5 years in private vs public health facilities in order to design interventions to improve quality of care. A survey was conducted within 57 geographical areas (parishes), from August to October 2014 in Mukono district, central Uganda. The survey comprised both facility and health worker assessment. Data were collected on drug stocks, availability of treatment guidelines, diagnostic equipment, and knowledge in management of malaria, pneumonia and diarrhoea, using a structured questionnaire. A total of 53 public and 241 private health facilities participated in the study. While similar proportions of private and public health facilities stocked Coartem, the first-line anti-malarial drug, (98 vs 95%, p = 0.22), significantly more private than public health facilities stocked quinine (85 vs 53%, p < 0.01). Stocks of obsolete anti-malarial drugs, such as chloroquine, were reported in few public and private facilities (3.7 vs 12.5%, p = 0.06). Stocks of antibiotics-amoxycillin and gentamycin were similar in both sectors (≥90% for amoxicillin; ≥50 for gentamycin). Training in malaria was reported by 65% of public health facilities vs 56% in the private sector, p = 0.25), while, only 21% in the public facility and 12% in the private facilities, p = 0.11, reported receiving training in pneumonia. Only 55% of public facilities had microscopes. Malaria treatment guidelines were significantly lacking in the private sector, p = 0.01. Knowledge about first-line management of uncomplicated malaria, pneumonia and diarrhoea was significantly better in the public facilities compared to the private ones, though still sub-optimal. Deficiencies of equipment, supplies and training exist even in public health

Acute febrile illness (AFI) is associated with substantial morbidity and mortality worldwide, yet an etiologic agent is often not identified. Convalescent-phase serology is impractical, blood culture is slow, and many pathogens are fastidious or impossible to cultivate. We developed a real-time PCR-based TaqMan array card (TAC) that can test six to eight samples within 2.5 h from sample to results and can simultaneously detect 26 AFI-associated organisms, including 15 viruses (chikungunya, Crimean-Congo hemorrhagic fever [CCHF] virus, dengue, Ebola virus, Bundibugyo virus, Sudan virus, hantaviruses [Hantaan and Seoul], hepatitis E, Marburg, Nipah virus, o'nyong-nyong virus, Rift Valley fever virus, West Nile virus, and yellow fever virus), 8 bacteria (Bartonella spp., Brucella spp., Coxiella burnetii, Leptospira spp., Rickettsia spp., Salmonella enterica and Salmonella enterica serovar Typhi, and Yersinia pestis), and 3 protozoa (Leishmania spp., Plasmodium spp., and Trypanosoma brucei). Two extrinsic controls (phocine herpesvirus 1 and bacteriophage MS2) were included to ensure extraction and amplification efficiency. Analytical validation was performed on spiked specimens for linearity, intra-assay precision, interassay precision, limit of detection, and specificity. The performance of the card on clinical specimens was evaluated with 1,050 blood samples by comparison to the individual real-time PCR assays, and the TAC exhibited an overall 88% (278/315; 95% confidence interval [CI], 84% to 92%) sensitivity and a 99% (5,261/5,326, 98% to 99%) specificity. This TaqMan array card can be used in field settings as a rapid screen for outbreak investigation or for the surveillance of pathogens, including Ebola virus.

We sought to assess the validity and short-term responsiveness of the Pediatric Quality of Life Inventory 4.0 Generic Core Scales (PedsQL) for febrile illnesses evaluated in the pediatric emergency department (ED). Prospective cohort study of children 2-18 years discharged after ED evaluation for fever (>or= 38 degrees C). Self-administered, parent-report of health-related quality of life (HRQOL) was assessed using the PedsQL Acute Version, a validated HRQOL instrument. HRQOL was measured on ED presentation and at 7-10 day follow-up. At follow-up, duration of fever, child functional impairment, missed daycare/school, and disrupted family unit functioning, were assessed. Of 160 subjects enrolled, 97 (61%) completed the study; mean follow-up was 8.7 days. Mean total HRQOL score on ED presentation was 76.4; mean follow-up score was 86.3. Compared to subjects that returned to baseline, statistically significant differences in HRQOL were noted for those with prolonged fever, child functional impairment, and relapse. Significant correlation was observed between HRQOL at follow-up and days of daycare/school missed (r = -0.35, p = .003) and days of family disruption (r = -0.43, p < .001). Mean change in HRQOL within subjects, from ED visit to follow-up, was +9.8 (95% CI: 5.6-14.6). Effect size was 0.53, indicating moderate responsiveness. The PedsQL appears to be a valid and responsive indicator of HRQOL for short-term febrile illnesses evaluated in the ED.

OBJECTIVES: This study identified possible dose-response relationships among bathers exposed to marine waters contaminated with domestic sewage and subsequent risk of nonenteric illness. METHODS: Four intervention follow-up studies were conducted within the United Kingdom. Healthy volunteers (n = 1273) were randomized into bather and nonbather groups. Intensive water-quality monitoring was used to assign five bacteriological indices of water quality to individual bathers. Illnesses studied were acute febrile respiratory illness, and eye, ear, and skin ailments. RESULTS: Fecal streptococci exposure was predictive of acute febrile respiratory illness, while fecal coliform exposure was predictive of ear ailments. Estimated thresholds of effect occurred at bather exposures above 60 fecal streptococci and 100 fecal coliform per 100 ml of water, respectively. Although no relationship was found between eye ailments and indicator organism exposure, compared with nonbathers, bathers were at higher risk for eye ailments. CONCLUSIONS: Nonenteric illness can be transmitted via recreational contact with marine waters contaminated with sewage. These results argue against the use of a single indicator to establish water quality standards. PMID:8806373

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.

Purpose We investigated whether C-reactive protein (CRP) levels, urine protein-creatinine ratio (uProt/Cr), and urine electrolytes can be useful for discriminating acute pyelonephritis (APN) from other febrile illnesses or the presence of a cortical defect on 99mTc dimercaptosuccinic acid (DMSA) scanning (true APN) from its absence in infants with febrile urinary tract infection (UTI). Materials and Methods We examined 150 infants experiencing their first febrile UTI and 100 controls with other febrile illnesses consecutively admitted to our hospital from January 2010 to December 2012. Blood (CRP, electrolytes, Cr) and urine tests [uProt/Cr, electrolytes, and sodium-potassium ratio (uNa/K)] were performed upon admission. All infants with UTI underwent DMSA scans during admission. All data were compared between infants with UTI and controls and between infants with or without a cortical defect on DMSA scans. Using multiple logistic regression analysis, the ability of the parameters to predict true APN was analyzed. Results CRP levels and uProt/Cr were significantly higher in infants with true APN than in controls. uNa levels and uNa/K were significantly lower in infants with true APN than in controls. CRP levels and uNa/K were relevant factors for predicting true APN. The method using CRP levels, u-Prot/Cr, u-Na levels, and uNa/K had a sensitivity of 94%, specificity of 65%, positive predictive value of 60%, and negative predictive value of 95% for predicting true APN. Conclusion We conclude that these parameters are useful for discriminating APN from other febrile illnesses or discriminating true APN in infants with febrile UTI. PMID:26632389

Malaria is a major contributor to the burden of febrile illnesses in Papua New Guinea (PNG). Dengue fever (DF) is likely to contribute; however, its epidemiology in PNG is poorly understood. 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.

Little is known about the prevalence and clinical course of dengue infection in elderly patients living in endemic areas; it is presumed that there is a lower prevalence but higher severity, complications and mortality.  To describe the prevalence and clinical course of dengue infection in elderly patients who were admitted to a referral care center for infectious diseases in an endemic region.  We conducted an observational and descriptive study between 2011 and 2014, using a cohort of elderly patients with serological diagnosis of dengue.  A total of 235 febrile elderly patients were assessed, of which 43 patients (18.3%) were found to have dengue. The median age was 71 years; 48.7% were female, and 89% of patients had at least one comorbid condition. According to the serological tests, 51.4% of cases were positive for NS1 Ag, 27% for IgM and 54.1% for IgG, while 64.8% were secondary infections. Dengue was diagnosed in 13 patients (35%), dengue with warning signs in 16 cases (43%), and severe dengue in 8 cases (22%). Nearly 56.7% of patients were admitted to hospital and 21.6%, to the intensive care unit. None died.  We found dengue infection to be more frequent than expected in this sample of elderly patients, due to acute febrile syndrome. Elderly patients also required higher rate of hospitalization and had more complications, however there were no deaths due to good management.

Revelation of Brugada electrocardiographic pattern during a febrile state associated with acute myocardial infarction.

PubMed

Patanè, Salvatore; Marte, Filippo

2010-09-24

The prevalence of the Brugada-type ECG and its natural history are still unclear. The Brugada syndrome is usually identified by a characteristic Brugada-type ECG that consists of ST elevation of a coved type in the precordial leads V1 to V3 and ventricular fibrillation that can lead to sudden cardiac death, although affected individuals may have a normal ECG. Mutations in the cardiac sodium channel gene SCN5A, which encodes the alpha-subunit of the human cardiac voltage-dependent Na+ channel (Na(v)1.5), are identified in 15-30% of patients with Brugada syndrome. Most SCN5A mutations lead to a 'loss-of-function' phenotype, reducing the Na+ current during the early phases of the action potential. Several nongenetic factors have been mentioned in the literature as possible inductors of the ECG pattern resembling Brugada syndrome. As such, a Brugada-type ECG may appear in some patients during febrile states and in those who are under the influence of cocaine and pharmaceutical drugs that have a sodium channel-blocking effect. It has been also reported chest pain and ST elevation Brugada pattern during febrile states. We present a case of revelation of Brugada pattern in a 69-year-old Italian man during a febrile state associated with acute myocardial infarction. Also this report confirms that Brugada pattern should be considered as one of differential diagnoses when we examine the patients during a febrile state. Copyright © 2008 Elsevier Ireland Ltd.

Leptospirosis is a worldwide zoonotic disease. Risk factors for the disease may vary among countries. This study was conducted to determine the risk factors of leptospirosis among febrile cases. A hospital-based cross-sectional study was conducted among 999 febrile patients admitted to 10 hospitals in northeastern Malaysia, from August 2010 to February 2011. An interviewer-guided proforma sheet on sociodemography, type of occupation and social history data was distributed to all adult patients with fever on admission. Serum sample for leptospirosis was screened by IgM Enzyme-linked Immunosorbent Assay (IgM ELISA) test and confirmed by Microscopic Agglutination Test (MAT). The cut-off point for positive MAT was ≥ 1:400 titer in single acute specimens. Seroprevalence of leptospirosis was 8.4% (95% CI: 6.8, 10.3) (n=84/999) by MAT. Multiple logistic regression analysis showed that the high risk occupation group (OR: 1.95, 95% CI: 1.22, 3.13) (p=0.005) and history of recent recreational activity (OR: 2.36, 95% CI: 1.46, 3.85) (p<0.001) were significant associated factors for leptospirosis. This study shows a relatively high seroprevalence of leptospirosis in northeastern Malaysia. Identification of high risk occupational group and history of recent recreational activity will help to increase the index of suspicion to diagnose leptospirosis among febrile inpatients due to its mimicking other common febrile illnesses in Malaysia.

Influenza-like illness (ILI) is often defined as fever (>38.0°C) with cough or sore throat. In this study, we tested the sensitivity, specificity, and positive and negative predictive values of this case definition in a Cambodia patient population. Passive clinic-based surveillance was established at nine healthcare centers to identify the causes of acute undifferentiated fever in patients aged two years and older seeking treatment. Fever was defined as tympanic membrane temperature >38°C lasting more than 24 hours and less than 10 days. Influenza virus infections were identified by polymerase chain reaction. From July 2008 to December 2008, 2,639 patients were enrolled. From 884 (33%) patients positive for influenza, 652 presented with ILI and 232 acute fever patients presented without ILI. Analysis by age group identified no significant differences between influenza positive patients from the two groups. Positive predictive values (PPVs) varied during the course of the influenza season and among age groups. The ILI case definition can be used to identify a significant percentage of patients with influenza infection during the influenza season in Cambodia, assisting healthcare providers in its diagnosis and treatment. However, testing samples based on the criteria of fever alone increased our case detection by 34%.

Febrile Infection-Related Epilepsy Syndrome (FIRES): An Overview of Treatment and Recent Patents.

2018-05-08

New-onset refractory status epilepticus (NORSE) refers to a clinical presentation in a patient without active epilepsy or other existing relevant neurological disorder, with new onset of refractory status epilepticus in the absence of a clear acute or active structural, metabolic, or toxic cause. Febrile infection-related epilepsy syndrome (FIRES) is a subset of NORSE that requires a febrile infection between 24 hours and 2 weeks prior to the onset of refractory status epilepticus, with or without fever at the onset of status epilepticus, and with no restriction to the age of the patient. The literature on FIRES is scarce. This article reviews the pathophysiology, clinical features, and various treatment modalities in the treatment of FIRES. A Medline/Pubmed search was conducted using Clinical Queries with the key terms "febrile infection-related epilepsy syndrome", "FIRES", "new-onset refractory status epilepticus" and "NORSE". The search strategy included meta-analyses, randomized controlled trials, clinical trials, reviews and pertinent references. Patents were searched using the key term "FIRES", "NORSE" and "febrile epilepsy syndrome" from www.google.com/patents, www.uspto.gov, and www.freepatentsonline.com. FIRES almost invariably begins with a mild nonspecific febrile illness in an otherwise healthy individual. Twenty four hours to two weeks later, seizures begin and quickly become very frequent and worsen, becoming status epilepticus. Seizures can be simple motor, complex partial or secondary generalized. The exact etiology is no known. It is possible that the syndrome is caused by an inflammatory or autoimmune mechanism. Seizures in FIRES are notoriously very difficult to treat. Treatment modalities include, among others, various antiepileptic drugs, ketogenic diet, intravenous corticosteroids, intravenous immunoglobulin, and burst-suppression coma. Outcome is poor; most children are left with significant cognitive disability

Dengue virus is an emerging infectious agent that infects an estimated 50–100 million people annually worldwide, yet current diagnostic practices cannot detect an etiologic pathogen in ∼40% of dengue-like illnesses. Metagenomic approaches to pathogen detection, such as viral microarrays and deep sequencing, are promising tools to address emerging and non-diagnosable disease challenges. In this study, we used the Virochip microarray and deep sequencing to characterize the spectrum of viruses present in human sera from 123 Nicaraguan patients presenting with dengue-like symptoms but testing negative for dengue virus. We utilized a barcoding strategy to simultaneously deep sequence multiple serum specimens, generating on average over 1 million reads per sample. We then implemented a stepwise bioinformatic filtering pipeline to remove the majority of human and low-quality sequences to improve the speed and accuracy of subsequent unbiased database searches. By deep sequencing, we were able to detect virus sequence in 37% (45/123) of previously negative cases. These included 13 cases with Human Herpesvirus 6 sequences. Other samples contained sequences with similarity to sequences from viruses in the Herpesviridae, Flaviviridae, Circoviridae, Anelloviridae, Asfarviridae, and Parvoviridae families. In some cases, the putative viral sequences were virtually identical to known viruses, and in others they diverged, suggesting that they may derive from novel viruses. These results demonstrate the utility of unbiased metagenomic approaches in the detection of known and divergent viruses in the study of tropical febrile illness. PMID:22347512

The burden of dengue in Africa is not well understood. A prospective study was conducted in Abidjan, Côte d'Ivoire from December 2011 to December 2012 to estimate the proportion of dengue and malaria cases among febrile patients during a period when dengue was not known to be circulating in the region, and to describe the clinical and virological characteristics of laboratory-diagnosed dengue cases. Blood samples were taken from febrile patients (body temperature ≥ 38°C) at two study sites. Patients with fever lasting more than 7 days, with fever of known origin and with jaundice were excluded. Thick blood film tests, ELISA for anti-dengue IgM and reverse transcription-PCR (RT-PCR) were performed. A total of 812 patients were enrolled (51.7% male [48.3% female]; 46.4% aged <10 years) of whom 796 (98.0%) provided IgM ELISA and RT-PCR data, and 807 (99.4%) had thick blood film results. Three (0.4%) patients had laboratory-diagnosed dengue (one with DENV-3 serotype), none of whom were diagnosed clinically, and 234 (28.8%) had confirmed malaria. This study suggests that dengue virus circulates in Abidjan outside an epidemic and that there should be an increase in awareness of dengue as a possible diagnosis in cases of undifferentiated fever. These results stress the importance of implementing laboratory capacity to assess dengue burden in Africa. © The Author 2015.

Dengue fever is endemic in many parts of the world but it has not been described as a cause of febrile neutropenia. We describe here clinical features, laboratory values and outcome in 10 children with acute lymphoblastic leukemia (ALL) and with dengue fever as a cause of febrile neutropenia. These data are compared to an age-matched control population of 22 children with proven dengue infection without ALL. Except for fever in all patients and plethoric face in one patient, typical symptoms of dengue such as abdominal pain, myalgias, and headaches, were absent. Mean duration of hospital stay was 6.3±2.0 days in ALL patients vs. 5.0±2.0 in controls (p=0.096). Median platelet count was 13,000/cmm (range 1000-28,000) in cases vs. 31,500 (range 13,000-150,000) in controls (p=0.018). Mean time for recovery for platelet was 6.0±1.3days in ALL patients vs. 2.5±0.9days in controls (p<0.001). All 10 patients survived. In endemic areas, high suspicion of dengue fever should be maintained in children with ALL and febrile neutropenia although typical symptoms may be lacking. Platelet recovery may be significantly delayed. Copyright © 2013 King Faisal Specialist Centre & Research Hospital. Published by Elsevier B.V. All rights reserved.

Working youths face many safety and health risks. Among these risks are those posed by disinfectant exposures. In this study we describe acute occupational disinfectant-related illness among youth. Data on U.S. children younger than 18 years with acute occupational disinfectant-related illnesses between 1993 and 1998 were collected from the Toxic Exposure Surveillance System and from the California Department of Pesticide Regulation. We analyzed data from persons with exposures who met the case definition for acute occupational disinfectant-related illness. The case definition required onset of new adverse health effects that were both temporally related to a disinfectant exposure and consistent with the known toxicology of the disinfectant. We calculated incidence rates of acute occupational disinfectant-related illness among youths 15-17 years old and incidence rate ratios to compare these rates with those of adults 25-44 years old. We found 307 children with disinfectant-related illnesses. The average annual incidence rate was 16.8/billion hours worked with a relative risk compared with adults of 4.14 (95% confidence interval, 3.66-4.68). Most illnesses were of mild severity (78%). There were no fatalities. Hypochlorites (e.g., bleach) were responsible for 45% of the illnesses. Among the 206 cases where the responsible disinfectant's U.S. Environmental Protection Agency toxicity category was known, 80% were in category I (highest toxicity level). These findings suggest the need for greater efforts to prevent adolescent acute occupational disinfectant-related illness. This may require strengthening regulations and enforcement as well as increased educational efforts directed at employers, youths, parents, school officials, and physicians. Better mechanisms for reporting and tracking chemical illnesses among working adolescents are also needed. PMID:14527846

The difficult coughing child: prolonged acute cough in children

PubMed Central

2013-01-01

Cough is one of the most common symptoms that patients bring to the attention of primary care clinicians. Cough can be designated as acute (<3 weeks in duration), prolonged acute cough (3 to 8 weeks in duration) or chronic (> 8 weeks in duration). The use of the term ‘prolonged acute cough’ in a cough guideline allows a period of natural resolution to occur before further investigations are warranted. The common causes are in children with post viral or pertussis like illnesses causing the cough. Persistent bacterial bronchitis typically occurs when an initial dry acute cough due to a viral infection becomes a prolonged wet cough remaining long after the febrile illness has resolved. This cough responds to a completed course of appropriate antibiotics. PMID:23574624

Illnesses Associated with Freshwater Recreation During International Travel.

2018-05-22

International travel, adventure travel, and eco-tourism are increasing over the past few decades. This review aims to summarize the spectrum of infections associated with recreational freshwater activities and international travel. Recreational water activities can be associated with a wide range of infections. Acute febrile illnesses due to leptospirosis and schistosomiasis are not uncommon in travelers following extensive freshwater exposure. Aeromonas and other water-associated pathogens are important to consider in a traveler presenting with a skin and soft tissue infection. Recreational water activities are often associated with diarrheal illnesses, especially in children, and the range of enteric pathogens includes bacterial pathogens such as Escherichia coli O157:H7 and Shigella species and the protozoan parasites Cryptosporidium and Giardia duodenalis. Infections due to free-living amebas though rare can lead to fulminant central nervous system infections. A diverse range of infections may be associated with freshwater exposure, and it is important that these entities are considered in a returning traveler presenting with an acute illness.

Brucellosis, Q fever and melioidosis are zoonoses, which can lead to pyrexia. These diseases are often under-ascertained and underreported because of their unspecific clinical signs and symptoms, insufficient awareness by physicians and public health officers and limited diagnostic capabilities, especially in low-resource countries. Therefore, the presence of Brucella spp., Coxiella burnetii and Burkholderia pseudomallei was investigated in Malagasy patients exhibiting febrile illness. In addition, we analyzed zebu cattle and their ticks as potential reservoirs for Brucella and C. burnetii, respectively. Specific quantitative real-time PCR assays (qPCRs) were performed on 1020 blood samples drawn from febrile patients. In total, 15 samples (1.5%) were Brucella-positive, mainly originating from patients without travel history, while DNA from C. burnetii and Bu. pseudomallei was not detected. Anti-C. burnetii antibodies were found in four out of 201 zebu serum samples (2%), whereas anti-Brucella antibodies could not be detected. Brucella DNA was detected in a single zebu sample. Three out of 330 ticks analyzed (1%) were positively tested for C. burnetii DNA but with high Ct values in the qPCR assay. Our data suggest that zebus as well as Amblyomma and Boophilus ticks have to be considered as a natural reservoir or vector for C. burnetii, but the risk of cattle-to-human transmission is low. Since bovine brucellosis does not seem to contribute to human infections in Madagascar, other transmission routes have to be assumed. Copyright © 2017 The Authors. Published by Elsevier B.V.

The goals were to describe the (1) frequency of sepsis evaluation and empiric antibiotic treatment, (2) clinical predictors of management, and (3) serious bacterial illness frequency for febrile infants with clinically diagnosed bronchiolitis seen in office settings. The Pediatric Research in Office Settings network conducted a prospective cohort study of 3066 febrile infants (<3 months of age with temperatures >or=38 degrees C) in 219 practices in 44 states. We compared the frequency of sepsis evaluation, parenteral antibiotic treatment, and serious bacterial illness in infants with and without clinically diagnosed bronchiolitis. We identified predictors of sepsis evaluation and parenteral antibiotic treatment in infants with bronchiolitis by using logistic regression models. Practitioners were less likely to perform a complete sepsis evaluation, urine testing, and cerebrospinal fluid culture and to administer parenteral antibiotic treatment for infants with bronchiolitis, compared with those without bronchiolitis. Significant predictors of sepsis evaluation in infants with bronchiolitis included younger age, higher maximal temperature, and respiratory syncytial virus testing. Predictors of parenteral antibiotic use included initial ill appearance, age of <30 days, higher maximal temperature, and general signs of infant distress. Among infants with bronchiolitis (N = 218), none had serious bacterial illness and those with respiratory distress signs were less likely to receive parenteral antibiotic treatment. Diagnoses among 2848 febrile infants without bronchiolitis included bacterial meningitis (n = 14), bacteremia (n = 49), and urinary tract infection (n = 167). In office settings, serious bacterial illness in young febrile infants with clinically diagnosed bronchiolitis is uncommon. Limited testing for bacterial infections seems to be an appropriate management strategy.

Clinicians in low resource settings in malaria endemic regions face many challenges in diagnosing and treating febrile illnesses in children. Given the change in WHO guidelines in 2010 that recommend malaria testing prior to treatment, clinicians are now required to expand the differential when malaria testing is negative. Prior studies have indicated that resource availability, need for additional training in differentiating non-malarial illnesses, and lack of understanding within the community of when to seek care play a role in effective diagnosis and treatment. The objective of this study was to examine the various factors that influence clinician behavior in diagnosing and managing children presenting with fever to health centres in Kenya. A total of 20 clinicians (2 paediatricians, 1 medical officer, 2 nurses, and 15 clinical officers) were interviewed, working at 5 different government-sponsored public clinic sites in two areas of Kenya where malaria is prevalent. Clinicians were interviewed one-on-one using a structured interview technique. Interviews were then analysed qualitatively for themes. The following five themes were identified: (1) Strong familiarity with diagnosis of malaria and testing for malaria; (2) Clinician concerns about community understanding of febrile illness, use of traditional medicine, delay in seeking care, and compliance; (3) Reliance on clinical guidelines, history, and physical examination to diagnose febrile illness and recognize danger signs; (4) Clinician discomfort with diagnosis of primary viral illness leading to increased use of empiric antibiotics; and (5) Lack of resources including diagnostic testing, necessary medications, and training modalities contributes to the difficulty clinicians face in assessing and treating febrile illness in children. These themes persisted across all sites, despite variation in levels of medical care. Within these themes, clinicians consistently expressed a need for reliable basic testing

Abstract Background Leptospirosis and human immunodeficiency virus (HIV) infection are prevalent in many areas, including northern Tanzania, yet little is known about their interaction. Methods We enrolled febrile inpatients at two hospitals in Moshi, Tanzania, over 1 year and performed HIV antibody testing and the microscopic agglutination test (MAT) for leptospirosis. Confirmed leptospirosis was defined as ≥four-fold rise in MAT titer between acute and convalescent serum samples, and probable leptospirosis was defined as any reciprocal MAT titer ≥800. Results Confirmed or probable leptospirosis was found in 70 (8.4%) of 831 participants with at least one serum sample tested. At total of 823 (99.0%) of 831 participants had HIV testing performed, and 203 (24.7%) were HIV infected. Among HIV-infected participants, 9 (4.4%) of 203 had confirmed or probable leptospirosis, whereas among HIV-uninfected participants 61 (9.8%) of 620 had leptospirosis. Leptospirosis was less prevalent among HIV-infected as compared to HIV-uninfected participants [odds ratio (OR) 0.43, p=0.019]. Among those with leptospirosis, HIV-infected patients more commonly presented with features of severe sepsis syndrome than HIV-uninfected patients, but differences were not statistically significant. Among HIV-infected patients, severe immunosuppression was not significantly different between those with and without leptospirosis (p=0.476). Among HIV-infected adolescents and adults, median CD4 percent and median CD4 count were higher among those with leptospirosis as compared to those with other etiologies of febrile illness, but differences in CD4 count did not reach statistical significance (p=0.015 and p=0.089, respectively). Conclusions Among febrile inpatients in northern Tanzania, leptospirosis was not more prevalent among HIV-infected patients. Although some indicators of leptospirosis severity were more common among HIV-infected patients, a statistically significant difference was not

To determine the effects of IV acetaminophen on core body temperature, blood pressure, and heart rate in febrile critically ill patients. Randomized, double-blind, placebo-controlled clinical trial. Three adult ICUs at a large, urban, academic medical center. Forty critically ill adults with fever (core temperature, ≥ 38.3°C). An infusion of acetaminophen 1 g or saline placebo over 15 minutes. Core temperature and vital signs were measured at baseline and at 5-15-minute intervals for 4 hours after infusion of study drug. The primary outcome was time-weighted average core temperature adjusted for baseline temperature. Secondary outcomes included adjusted time-weighted average heart rate, blood pressure, and respiratory rate, along with changes-over-time for each. Baseline patient characteristics were similar in those given acetaminophen and placebo. Patients given acetaminophen had an adjusted time-weighted average temperature that was 0.47°C less than those given placebo (95% CI, -0.76 to -0.18; p = 0.002). The acetaminophen group had significantly lower adjusted time-weighted average systolic blood pressure (-17 mm Hg; 95% CI, -25 to -8; p < 0.001), mean arterial pressure (-7 mm Hg; 95% CI, -12 to -1; p = 0.02), and heart rate (-6 beats/min; 95% CI, -10 to -1; p = 0.03). Changes-over-time temperature, blood pressure, and heart rate outcomes were also significantly lower at 2 hours, but not at 4 hours. Among febrile critically ill adults, treatment with acetaminophen decreased temperature, blood pressure, and heart rate. IV acetaminophen thus produces modest fever reduction in critical care patients, along with clinically important reductions in blood pressure.

Acute gastrointestinal illness is an important public-health issue worldwide. Burden-of-illness studies have not previously been conducted in Cuba. The objective of the study was to determine the magnitude, distribution, and burden of self-reported acute gastrointestinal illness in Cuba. A retrospective, cross-sectional survey was conducted in three sentinel sites during June-July 2005 (rainy season) and during November 2005–January 2006 (dry season). Households were randomly selected from a list maintained by the medical offices in each site. One individual per household was selected to complete a questionnaire in a face-to-face interview. The case definition was three or more bouts of loose stools in a 24-hour period within the last 30 days. In total, 97.3% of 6,576 interviews were completed. The overall prevalence of acute gastrointestinal illness was 10.6%. The risk of acute gastrointestinal illness was higher during the rainy season (odds ratio [OR]=3.85, 95% confidence interval [CI] 3.18-4.66) in children (OR=3.12, 95% CI 2.24-4.36) and teens (OR=2.27, 95% CI 1.51-3.41) compared to people aged 25-54 years, in males (OR=1.24, 95% CI 1.04-1.47), and in the municipality of Santiago de Cuba (OR=1.33, 95% CI 1.11-1.61). Of 680 cases, 17.1-38.1% visited a physician, depending on sentinel site. Of the cases who visited a physician, 33.3-53.9% were requested to submit a stool sample, and of those, 72.7-100.0% complied. Of the cases who sought medical care, 16.7- 61.5% and 0-31.6% were treated with antidiarrhoeals and antibiotics respectively. Acute gastrointestinal illness represented a substantial burden of health compared to developed countries. Targeting the identified risk factors when allocating resources for education, food safety, and infrastructure might lower the morbidity associated with acute gastrointestinal illness. PMID:19507750

Febrile neutropaenia is a common complication of chemotherapy in cancer patients. Empirical antibiotic regimes are based on the epidemiological characteristics of bacterial isolates globally and locally. This study retrospectively reviewed all cases of febrile neutropaenia in patients with confirmed cancer admitted at the University Hospital of the West Indies in the four-year period between, January 1, 2003 and December 31, 2006 and who received chemotherapy. Cases were identified from blood culture records and hospital charts which were reviewed to determine the aetiological agents causing bacteraemia, their antimicrobial susceptibilities and clinicalfeatures. These cases were compared with non-neutropaenic cancer patients admitted with fever. A total of 197 febrile episodes in cancer patients were reviewed. Thirty-seven per cent had febrile neutropaenia while 62% were non-neutropaenic. Acute myeloid leukaemia was the most common haematological malignancy and the most common solid tumour was breast cancer. Twenty-six per cent of patients had a positive blood culture. In febrile neutropaenic patients, Escherichia coli was the most common organism isolated followed by coagulase-negative staphylococci while in non-neutropaenic patients, coagulase-negative staphylococci was most common. Acinetobacter infections was prominent in non-neutropaenic patients but absent in neutropaenic patients. More than one organism was cultured in 9 neutropaenic and 18 non-neutropaenic patients. Mortality was 10.8% in neutropaenic and 24.4% in non-neutropaenic patients. Gram-negative organisms are the predominant isolates in febrile neutropaenic episodes in this cohort of patients. Non-neutropaenic patients had an increased mortality with an increase in Acinetobacter infections and multiple isolates.

Shivering in acutely ill vulnerable populations.

Holtzclaw, Barbara J

2004-01-01

The hazards of thermoregulatory shivering in the critically ill are often overlooked by caregivers. Shivering may accompany heat loss from bathing, dressing, transport, and many therapeutic activities. Febrile shivering is common during chills of fever, blood product transfusions, administration of antigenic drugs, and chemotherapy. Many patients are at risk for shivering and its negative consequences that increase oxygen expenditure and cardiorespiratory effort. Learning how underlying thermoregulatory mechanisms are involved in shivering clarifies how temperature gradients and environmental stimuli induce the shivering response. Knowledge of the anatomical progression of shivering equips the nurse to recognize or prevent this energy-consuming response. This article discusses measures to prevent shivering as well as evidence-based interventions to manage shivering during fever, aggressive cooling, and postoperative recovery. Detailed information is presented on assessment and documentation of the extent and severity of shivering.

The second year of the study is reported. Electoral ward of Sparkbrook, Birmingham. 99 Patients aged 16-65 with severe acute psychiatric illness. 65 Patients were managed by home treatment alone; 34 required admission to hospital. The location of treatment was significantly (all p less than 0.05) influenced by social characteristics of the patients (marital state, age (in men), ethnicity, and living alone) and by characteristics of the referral (occurring out of hours; assessment taking place at hospital or police station). DSM-III-R diagnosis was more weakly associated with outcome. Violence during the episode was significantly related to admission, although deliberate self harm was not. Home treatment is feasible for most patients with acute psychiatric illness. A 24 hour on call assessment service increases the likelihood of success because admission is determined more strongly by social characteristics of the patient and the referral than by illness factors. Admission will still be required for some patients. A locally based mental health resource centre, a 24 hour on call service, an open referral system, and an active follow up policy increase the effectiveness of a home treatment service.

2017-01-01

Introduction The clinical features of UTI in young children may not localize to the urinary tract and closely resemble other febrile illnesses. In malaria endemic areas, a child presenting with fever is often treated presumptively for malaria without investigation for UTI. Delayed or inadequate treatment of UTI increases the risk of bacteremia and renal scarring in young children and subsequently complications as hypertension and end stage renal disease in adulthood. Methods A cross-sectional study was carried out in a hospital in western Kenya. Inpatients and outpatients 2 months to five years with axillary temperature ≥37.5°C and no antibiotic use in the previous week were enrolled between September 2012 and April 2013. Urine dipstick tests, microscopy, and cultures were done and susceptibility patterns to commonly prescribed antibiotics established. UTI was defined as presence of pyuria (a positive urine dipstick or microscopy test) plus a positive urine culture. Results A total of 260 subjects were recruited; 45.8% were female and the median age was 25months (IQR: 13, 43.5). The overall prevalence of UTI was 11.9%. Inpatients had a higher prevalence compared to outpatients (17.9% v 7.8%, p = 0.027). UTI co-existed with malaria but the association was not significant (OR 0.80, p = 0.570). The most common organisms isolated were Escherichia coli (64.5%) and Staphylococcus aureus (12.9%) and were sensitive to ciproflaxin, cefuroxime, ceftriaxone, gentamycin and nitrofurantoin but largely resistant to more commonly used antibiotics such as ampicillin (0%), amoxicillin (16.7%), cotrimoxazole (16.7%) and amoxicillin-clavulinate (25%). Conclusion Our study demonstrates UTI contributes significantly to the burden of febrile illness in young children and often co-exists with other infections. Multi-drug resistant organisms are common therefore choice of antimicrobial therapy should be based on local sensitivity pattern. PMID:28323886

The most common organisms isolated were Escherichia coli (64.5%) and Staphylococcus aureus (12.9%) and were sensitive to ciproflaxin, cefuroxime, ceftriaxone, gentamycin and nitrofurantoin but largely resistant to more commonly used antibiotics such as ampicillin (0%), amoxicillin (16.7%), cotrimoxazole (16.7%) and amoxicillin-clavulinate (25%). Our study demonstrates UTI contributes significantly to the burden of febrile illness in young children and often co-exists with other infections. Multi-drug resistant organisms are common therefore choice of antimicrobial therapy should be based on local sensitivity pattern.

Kawasaki disease (KD) is an acute febrile illness of childhood associated with vasculitis of medium-sized arteries especially the coronary arteries. Typical clinical features involving the skin, mucous surfaces, etc., occur sequentially over a few days. We report a rare presentation of KD as a surgical abdomen in a 2-year-old boy. Awareness of this presentation is important as it can otherwise lead to a delay in starting potentially life-saving intervention like intravenous immunoglobulins for cardiac complications kept cryptic by the manifest acute abdomen.

Signals generating anorexia during acute illness.

PubMed

Langhans, Wolfgang

2007-08-01

Anorexia is part of the body's acute-phase response to illness. Microbial products such as lipopolysaccharides (LPS), which are also commonly used to model acute illness, trigger the acute-phase response and cause anorexia mainly through pro-inflammatory cytokines. LPS stimulate cytokine production through the cell-surface structural molecule CD14 and toll-like receptor-4. Cytokines ultimately change neural activity in brain areas controlling food intake and energy balance. The blood-brain barrier endothelial cells (BBB EC) are an important site of cytokine action in this context. BBB EC and perivascular cells (microglia and macrophages) form a complex regulatory interface that modulates neuronal activity by the release of messengers (e.g. PG, NO) in response to peripheral challenges. Serotonergic neurons originating in the raphe nuclei and glucagon-like peptide-1-expressing neurons in the hindbrain may be among the targets of these messengers, because serotonin (5-HT), acting through the 5-HT2C receptor, and glucagon-like peptide-1 have recently emerged as neurochemical mediators of LPS anorexia. The central melanocortin system, which is a downstream target of serotonergic neurons, also appears to be involved in mediation of LPS anorexia. Interestingly, LPS also reduce orexin expression and the activity of orexin neurons in the lateral hypothalamic area of fasted mice. As the eating-stimulatory properties of orexin are apparently related to arousal, the inhibitory effect of LPS on orexin neurons might be involved in LPS-induced inactivity and anorexia. In summary, the immune signalling pathways of LPS-induced, and presumably acute illness-induced, anorexia converge on central neural signalling systems that control food intake and energy balance in healthy individuals.

Empirical knowledge suggests that acute neurologic disorders are common in sub-Saharan Africa, but studies examining the true burden of these diseases in children are scarce. We performed this prospective, observational study to evaluate the prevalence, clinical characteristics, treatment approaches, and outcomes of children suffering acute neurologic illness or injury (ANI) in an urban and rural site in the Democratic Republic of the Congo. Over 12 months, 471 out of 6,563 children admitted met diagnostic criteria for ANI, giving a hospital-based prevalence of 72/1,000 admissions. Two hundred and seventy-two children had clinical findings consistent with central nervous system infection but lacked complete diagnostic evaluation for definitive classification. Another 151 children were confirmed to have cerebral malaria ( N = 109, 23% of admissions), bacterial meningitis ( N = 38, 8% of admissions), tuberculous meningitis ( N = 3, 0.6% of admissions), or herpes encephalitis ( N = 1, 0.21% of admissions). Febrile convulsions, traumatic brain injury, and epilepsy contributed less significantly to overall hospital prevalence of ANI (3.19/1,000, 1.37/1,000, and 1.06/1,000, respectively). Overall mortality for the cohort was 21% (97/471). Neurologic sequelae were seen in another 31% of participants, with only 45% completing the study with a normal neurologic examination. This type of data is imperative to help plan effective strategies for illness and injury prevention and control, and to allow optimal use of limited resources in terms of provision of acute care and rehabilitation for these children.

Acute febrile illnesses comprise the majority of the human disease burden in sub-Saharan Africa. We hypothesized that arboviruses comprised a considerable proportion of undiagnosed febrile illnesses in Guinea and sought to determine the frequency of arboviral disease in two hospitals there. Using a standard case definition, 47 suspected cases were detected in approximately 4 months. Immunoglobulin M antibody capture enzyme-linked immunosorbent assays and plaque-reduction neutralization assays revealed that 63% (30/47) of patients were infected with arboviruses, including 11 West Nile, 2 yellow fever, 1 dengue, 8 chikungunya, and 5 Tahyna infections. Except for yellow fever, these are the first reported cases of human disease from these viruses in Guinea and the first reported cases of symptomatic Tahyna infection in Africa. These results strongly suggest that arboviruses circulate and are common causes of disease in Guinea. Improving surveillance and laboratory capacity for arbovirus diagnoses will be integral to understanding the burden posed by these agents in the region.

To report a case of Purtscher-like retinopathy with paracentral acute middle maculopathy preceded by febrile illness after filler injection into the buttock muscles bilaterally for cosmesis to achieve a "Brazilian booty." Retrospective case report. A 35-year-old female presented with febrile illness and then decreased vision after repeat polymethyl methacrylate injections into her buttock muscles in Mexico. Examination was significant for retinal whitening, especially in the perifoveal areas, and intraretinal hemorrhages. Optical coherence tomography and fluorescein angiography imaging were consistent with small-vessel ischemic disease in the retina and choroid. Once systemic infection was ruled out, patient was treated with high-dose intravenous and then oral steroids. Vision recovery was good, with retinal atrophy on optical coherence tomography in the previous areas of retinal whitening. A Purtscher-like retinopathy with paracentral acute middle maculopathy and loss of vision may occur after filler injection below the neck, not just the face. This is the first report of vision loss caused by filler injected outside the face.

Alcohol-based hand sanitizer (HS) kills most organisms that cause acute illness, an important cause of lost duty time among aviation personnel. This preliminary study observed the impact on the acute illness rate when HS was made readily accessible to pilots. Wall-mounted HS dispensers were placed in two fighter squadron operations buildings during November 2005 and various media were used to alert all base personnel to the importance of hand hygiene and cough hygiene. Data were obtained for two groups of personnel on the same base: 1) pilots who worked in the two HS-equipped buildings (Squadron) (n = 56); and 2) pilots and air traffic controllers who worked at other locations (Non-Squadron) (n = 61). The incidence of acute illness and the cumulative number of duty days lost was determined in each group for the winters of 2004-05 (no HS) and 2005-06 (HS available). For the Squadron group, the acute illness rates were 2.4% in 2004-5 (210 duty days lost) (no HS) compared with 0.9% in 2005-6 (78 duty days lost) when HS was provided. No year-to-year difference was apparent for the Non-Squadron group, where the illness rates were 2.4% in 2004-5 (229 duty days lost) and 2.3% in 2005-6 (221 duty days lost). Making HS readily available at locations frequented by pilots together with educating them regarding hand hygiene may reduce the occurrence of acute illness and number of duty days lost.

Severe anaemia in children is a leading cause of hospital admission and a major cause of mortality in sub-Saharan Africa, yet there are limited published data on blood transfusion in this vulnerable group. We present data from a large controlled trial of fluid resuscitation (Fluid Expansion As Supportive Therapy (FEAST) trial) on the prevalence, clinical features, and transfusion management of anaemia in children presenting to hospitals in three East African countries with serious febrile illness (predominantly malaria and/or sepsis) and impaired peripheral perfusion. Of 3,170 children in the FEAST trial, 3,082 (97%) had baseline haemoglobin (Hb) measurement, 2,346/3,082 (76%) were anaemic (Hb <10 g/dL), and 33% severely anaemic (Hb <5 g/dL). Prevalence of severe anaemia varied from 12% in Kenya to 41% in eastern Uganda. 1,387/3,082 (45%) children were transfused (81% within 8 hours). Adherence to WHO transfusion guidelines was poor. Among severely anaemic children who were not transfused, 52% (54/103) died within 8 hours, and 90% of these deaths occurred within 2.5 hours of randomisation. By 24 hours, 128/1,002 (13%) severely anaemic children had died, compared to 36/501 (7%) and 71/843 (8%) of those with moderate and mild anaemia, respectively. Among children without severe hypotension who were randomised to receive fluid boluses of 0.9% saline or albumin, mortality was increased (10.6% and 10.5%, respectively) compared to controls (7.2%), regardless of admission Hb level. Repeat transfusion varied from ≤2% in Kenya/Tanzania to 6 to 13% at the four Ugandan centres. Adverse reactions to blood were rare (0.4%). Severe anaemia complicates one third of childhood admissions with serious febrile illness to hospitals in East Africa, and is associated with increased mortality. A high proportion of deaths occurred within 2.5 hours of admission, emphasizing the need for rapid recognition and prompt blood transfusion. Adherence to current WHO transfusion guidelines was

Aromatase Blockade Is Associated With Increased Mortality in Acute Illness in Male Mice.

PubMed

Connerney, Jeannette J; Spratt, Daniel I

The increase in circulating estrogen levels with acute illness in humans is accompanied by increased aromatase expression in adipose tissue and increased peripheral aromatization of estrogens to androgens. Animal studies indicate that estrogen may be beneficial in acute illness. We hypothesized that blockade of aromatase in acute illness would decrease survival. Prospective sham controlled. Maine Medical Center Research Institute animal facility. Six- to 8-week-old male black 6 mice. Mice underwent cecal ligation and puncture (CLP) to induce acute illness and were administered letrozole to block aromatase or saline. Mice undergoing sham surgery with or without letrozole served as controls. Adipose and cardiovascular tissue was harvested for preliminary evaluation of aromatase expression. Survival was the main outcome measurement. Evidence for aromatase expression in tissue samples was assessed using western blot and/or immunohistochemistry. With aromatase blockade, survival in CLP mice was decreased ( P = 0.04). The presence of aromatase in adipose tissue was observed by western blot in CLP but not control mice. Similarly, the presence of aromatase was observed in cardiac tissue of CLP but not in control mice. The decreased survival during sepsis with aromatase blockade suggests that this response to acute illness may be important both physiologically and clinically. The preliminary observation of aromatase expression in adipose and cardiovascular tissue during acute illness in this mouse model indicates that this model has parallels to human physiology and may be useful for further studying the aromatase response to acute illness.

Our genetic analyses of uncharacterized bunyaviruses isolated in Peru identified a possible reassortant virus containing small and large gene segment sequences closely related to the Caraparu virus and a medium gene segment sequence potentially derived from an unidentified group C orthobunyavirus. Neutralization tests confirmed serologic distinction among the newly identified virus and the prototype and Caraparu strains. This virus, named Itaya, was isolated in 1999 and 2006 from febrile patients in the cities of Iquitos and Yurimaguas in Peru. The geographic distance between the 2 cases suggests that the Itaya virus could be widely distributed throughout the Amazon basin in northeastern Peru. Identification of a new Orthobunyavirus species that causes febrile disease in humans reinforces the need to expand viral disease surveillance in tropical regions of South America.

A new look on brain mechanisms of acute illness anorexia.

PubMed

Asarian, Lori; Langhans, Wolfgang

2010-07-14

Bacterial lipopolysaccharide (LPS) and other microbial substances trigger the organism's acute phase response and cause acute illness anorexia. Pro-inflammatory cytokines are major endogenous mediators of acute illness anorexia, but how LPS or cytokines stimulate the brain to inhibit eating is not fully resolved. One emerging mechanism involves the activation of the enzyme cyclooxygenase-2 (COX-2) in blood-brain barrier endothelial cells and the subsequent release of prostaglandin E2 (PGE2). Serotonin neurons in the midbrain raphe are targets of PGE2, and serotonergic projections from the midbrain raphe to the hypothalamus appear to be crucial for LPS anorexia. That is, raphe projections activate (1) the corticotrophin-releasing hormone neurons in the paraventricular nucleus which then elicit the stress response and (2) the pro-opiomelanocortin neurons in the arcuate nucleus which then release alphaMSH and elicit anorexia. Here we review available data to support a role for this brain mechanism in acute illness anorexia by center staging PGE2 signaling pathways that converge on central neural circuits that control normal eating. In addition, we review interactions between gonadal hormones and immune function that lead to sex differences in acute illness anorexia.

Clinician assessment for acute chest syndrome in febrile patients with sickle cell disease: is it accurate enough?

To determine whether the use of empiric chest radiography (CXR) is of significant value in detecting clinically unsuspected acute chest syndrome (ACS) in febrile patients with sickle cell disease (SCD). Patients with SCD presenting to the emergency department and hematology clinic with temperature greater than or equal to 38 degrees C were prospectively evaluated using a physician-completed questionnaire. The questionnaire included inquiries into the patient's physical signs and symptoms and the physician's clinical impression for the presence of ACS. The questionnaire was completed before obtaining CXR results in all patients. Seventy-three patients with SCD with 96 febrile events were evaluated over a 1-year period. Twenty-four percent (23/96) of the patients had CXR evidence of ACS. On the basis of the questionnaire data, 61% (14/23) of ACS cases were not clinically suspected by the evaluating physician before obtaining CXR. Comparing the patients with and without ACS revealed that, with the exception of splinting (4/23 [17%] versus 0/73 [0%]), no symptom or physical examination finding helped to identify which patients had ACS. Fifty-seven percent of patients with ACS had completely normal findings on physical examination. The presentation of patients with clinically detected versus clinically unsuspected ACS also did not differ significantly. Length of hospitalization, oxygen use, and need for transfusion were the same in both the unsuspected and detected ACS groups. Overall physician sensitivity for predicting ACS was only 39%, and diagnostic accuracy did not improve significantly with increasing levels of pediatric training. ACS is common in patients with SCD who present with fever and was grossly underestimated by evaluating physicians. History and physical examination appear to be of little value in defining which febrile patients require CXR. In view of the mortality and morbidity associated with ACS, empiric CXR should be considered when evaluating a

Mexico and Central America are important travel destinations for North American and European travelers. There is limited information on regional differences in travel related morbidity. We describe the morbidity among 4779 ill travelers returned from Mexico and Central America who were evaluated at GeoSentinel network clinics during December 1996 to February 2010. The most frequent presenting syndromes included acute and chronic diarrhea, dermatologic diseases, febrile systemic illness, and respiratory disease. A higher proportion of ill travelers from the United States had acute diarrhea, compared with their Canadian and European counterparts (odds ratio, 1.9; P < .0001). During the 2009 H1N1 influenza outbreak from March 2009 through February 2010, the proportionate morbidity (PM) associated with respiratory illnesses in ill travelers increased among those returned from Mexico, compared with prior years (196.0 cases per 1000 ill returned travelers vs 53.7 cases per 1000 ill returned travelers; P < .0001); the PM remained constant in the rest of Central America (57.3 cases per 1000 ill returned travelers). We identified 50 travelers returned from Mexico and Central America who developed influenza, including infection due to 2009 H1N1 strains and influenza-like illness. The overall risk of malaria was low; only 4 cases of malaria were acquired in Mexico (PM, 2.2 cases per 1000 ill returned travelers) in 13 years, compared with 18 from Honduras (PM, 79.6 cases per 1000 ill returned travelers) and 14 from Guatemala (PM, 34.4 cases per 1000 ill returned travelers) during the same period. Plasmodium vivax malaria was the most frequent malaria diagnosis. Travel medicine practitioners advising and treating travelers visiting these regions should dedicate special attention to vaccine-preventable illnesses and should consider the uncommon occurrence of acute hepatitis A, leptospirosis, neurocysticercosis, acute Chagas disease, onchocerciasis, mucocutaneous leishmaniasis

Infections and infectious complications are the major cause of morbidity and mortality in febrile neutropenic patients after autologous stem cell transplantation. Laboratory biomarkers are helpful for early identification of critically ill patients and optimal therapy management. Several studies in adult non-neutropenic patients proposed sTREM-1 as a superior biomarker for identification of septic patients as well as a predictor for survival in these patients compared with procalcitonin (PCT), C-reactive protein (CRP), or interleukin-8 (IL-8). Here, to assess the utility of PCT, CRP, IL-8, and sTREM-1 in febrile neutropenia, 44 patients presenting with febrile neutropenia after autologous stem cell transplantation were recruited in a single-center prospective pilot study. We analyzed PCT and CRP as well as IL-8 and sTREM-1 levels pre- and post-transplantation at defined time points. In 20 of 44 patients, concentration of sTREM-1 was under the detection level at appearance of febrile neutropenia. Mean levels of PCT, IL-8, and CRP were significantly increased in infections of critically ill patients who by dysfunction or failure of one or more organs/system depend on survival from advanced instruments of monitoring and therapy. However, all tested biomarkers could not distinguish between presence and absence of bloodstream infection. The combination of the biomarkers PCT and IL-8 achieved a high sensitivity of 90% and specificity of 74% for the identification of serious complications in febrile neutropenia, whereas the combination of CRP and PCT or IL-8 achieved a high sensitivity of 100%, but with the addition of a low specificity of 47or 41%. In conclusion, we found that the measurement of sTREM-1 concentration at presentation of febrile neutropenia is not useful to identify bacterial bloodstream infections and critically ill patients. PCT and IL-8 are useful biomarkers for the early identification of critically ill patients, compared to CRP and sTREM-1 in febrile

We sought to characterize dengue virus (DENV) infections among febrile children enrolled in a pediatric cohort study who were clinically diagnosed with a non-dengue illness ("C cases"). DENV infections were detected and viral load quantitated by real-time reverse transcription-polymerase chain reaction in C cases presenting between January 2007 and January 2013. One hundred forty-one of 2892 C cases (4.88%) tested positive for DENV. Of all febrile cases in the study, DENV-positive C cases accounted for an estimated 52.0% of patients with DENV viremia at presentation. Compared with previously detected, symptomatic dengue cases, DENV-positive C cases were significantly less likely to develop long-lasting humoral immune responses to DENV, as measured in healthy annual serum samples (79.7% vs 47.8%; P < .001). Humoral immunity was associated with viral load at presentation: 40 of 43 patients (93.0%) with a viral load ≥7.0 log10 copies/mL serum developed the expected rise in anti-DENV antibodies in annual samples versus 13 of 68 (19.1%) patients with a viral load below this level (P < .001). Antibody responses to DENV-positive C cases differ from responses to classic symptomatic dengue. These findings have important implications for DENV transmission modeling, immunology, and epidemiologic surveillance. © The Author 2017.

Quibdó, a municipality in Chocó, has poor public services and weather and social conditions that favor dengue transmission. However, there are few studies about this problem in this district. To determine the frequency of dengue infection in patients with acute febrile syndrome and to compare clinical features among dengue infected patients with other febrile diseases. A cross-sectional study was conducted from January, 2008, to March, 2010. The study population comprised patients with febrile syndrome of seven or fewer days of evolution, recruited from hospitals in the town. Dengue diagnosis was made in serum samples by detection of IgM antibodies, NS1 antigen, reverse transcription polymerase chain reaction, and virus isolation. Clinical and laboratory information from the patients was obtained. During the study period, 469 patients with acute febrile syndrome were recruited, of whom 98.3% were Afro-descendant. Dengue fever was found in 28.4% of the cases. Four dengue serotypes were identified with DENV-1 predominance. The ages ranged from zero to 76 years. From all patients, 70.7% of cases were classified as dengue without warning signs. Nausea, vomiting, abdominal pain, cough, nasal congestion and sore throat were significantly more frequent in patients with another febrile disease. Active surveillance of the acute febrile syndrome allowed for the detection of undiagnosed cases of dengue; the observed frequency of this infection suggests that the study area has a high risk of dengue infection.

Shared Decision-Making with Parents of Acutely Ill Children: A Narrative Review.

PubMed

Aronson, Paul L; Shapiro, Eugene D; Niccolai, Linda M; Fraenkel, Liana

Shared decision-making (SDM) has mostly been used with adults and parents in the primary care setting, and there is limited knowledge on the use of SDM with parents of acutely ill children. The objective of this study was to review the literature on SDM with parents in the management of acutely ill children. We searched MEDLINE, SCOPUS, PsycINFO, the Cochrane Library, and ClinicalTrials.gov for English language studies published from the time of database inception to February, 2017. Study eligibility criterion was use of SDM with parents for children aged 18 years or younger with an acute medical problem. We identified 2 ongoing clinical trials and 10 published studies that met inclusion criteria: 2 using hypothetical SDM scenarios, 1 mixed methods study, and 7 intervention studies. Only 1 study compared an SDM intervention with usual care in a randomized controlled trial. The limited literature shows that parents of acutely ill children have differing preferences for testing and/or treatment, and that they generally want the opportunity to express those preferences through an SDM process. Use of SDM often results in acutely ill children undergoing fewer and/or less intensive testing or treatment, although the effect on outcomes is unclear. Parents welcome participation in SDM for management decisions with their acutely ill child. Further investigation is needed to determine how best to implement SDM with parents of acutely ill children and to assess the effect of SDM on outcomes.

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.

Sarcopenia in cases of chronic and acute illness. A mini-review.

2016-02-01

Loss of muscle mass and muscle weakness are often found in cases of acute or chronic illness in elderly patients. Sarcopenia is a risk factor for complications and higher mortality. Based on an exact diagnosis and knowledge of the risk factors for developing sarcopenia, it is now possible to improve the prognosis by providing effective treatment options. This review was carried out based on a PubMed search in the period from 1998 to 2015 using original articles and reviews and posting the terms "sarcopenia", "elderly" and "acute illness". Given the evidence from the current literature, in the case of acute illness it is feasible to identify patients at risk, diagnose sarcopenia and prescribe a multidimensional treatment program to prevent or treat sarcopenia even in the bustling environment of geriatric wards or institutions.

The purpose of this survey was to study the beliefs, expectations, and satisfaction of Canadian parents regarding fever and the treatment of their febrile children. A survey was developed exploring caregiver beliefs and treatment strategies, as well as expectations and satisfaction with medical care. Some items were modeled after previous studies to allow comparison. Caregivers with febrile children were recruited from 2005 to 2007 at 3 urgent care centers and emergency departments in Edmonton, Canada: a pediatric emergency department (n = 376), an urban urgent care center (n = 227), and a suburban urgent care clinic (n = 173). High and rapidly rising temperature, as well as physical symptoms associated with fever, caused concern in most parents surveyed. Seventy-four percent of parents felt that the elevated temperature from fever was dangerous and 90.3% always try to treat it. Forty degrees Celsius was the most commonly sited threshold for danger. Identifying the cause (80.6%) and seriousness (87.4%) of fever were the most com-mon stressors identified. Caregivers expected to receive information about the child's illness and appropriate treatment. The parents most often wanted information about febrile seizures and the potential dangers of febrile illness. Only 16.7% of caregivers expected anti-biotics. Nearly 92% of subjects were usually satisfied with medical care. Fever phobia continues to be a significant issue for Canadian parents. As a result, they treat fever aggressively and often seek medical attention. Good communication is important for medical staff caring for febrile children and typically leads to satisfied parents.

Viruses detected in patients with acute respiratory infections may be the cause of illness or asymptomatic shedding. To estimate the attributable fraction (AF) and the detection rate attributable to illness for each of the different respiratory viruses We compared the prevalence of 10 common respiratory viruses (influenza A and B viruses, parainfluenza virus 1-3; respiratory syncytial virus (RSV); adenovirus, rhinovirus, human metapneumovirus (hMPV) and enterovirus) in both HIV positive and negative patients hospitalized with severe acute respiratory illness (SARI), outpatients with influenza-like illness (ILI), and control subjects who did not report any febrile, respiratory or gastrointestinal illness during 2012-2015 in South Africa. We enrolled 1959 SARI, 3784 ILI and 1793 controls with a HIV sero-prevalence of 26%, 30% and 43%, respectively. Influenza virus (AF: 86.3%; 95%CI: 77.7-91.6%), hMPV (AF: 85.6%; 95%CI: 72.0-92.6%), and RSV (AF: 83.7%; 95%CI: 77.5-88.2%) infections were associated with severe disease., while rhinovirus (AF: 46.9%; 95%CI: 37.6-56.5%) and adenovirus (AF: 36.4%; 95%CI: 20.6-49.0%) were only moderately associated. Influenza, RSV and hMPV can be considered pathogens if detected in ILI and SARI while rhinovirus and adenovirus were commonly identified in controls suggesting that they may cause only a proportion of clinical disease observed in positive patients. Nonetheless, they may be important contributors to disease. Copyright © 2015 Elsevier B.V. All rights reserved.

Paraquat and diquat are among the most commonly used herbicides in the world. Determine the magnitude, characteristics, and root causes for acute paraquat- and diquat-related illnesses in the US METHODS: Illnesses associated with paraquat or diquat exposure occurring from 1998 through 2011 were identified from the Sentinel Event Notification System for Occupational Risks (SENSOR)-Pesticides Program, the California Department of Pesticide Regulation (CDPR) Pesticide Illness Surveillance Program (PISP), and the Incident Data System (IDS). Cases identified by the National Poison Data System (NPDS) were reviewed for the years 1998-2003 and 2006-2013. A total of 300 paraquat- and 144 diquat-related acute illnesses were identified by SENSOR, PISP, and IDS. NPDS identified 693 paraquat- and 2128 diquat-related acute illnesses. In SENSOR/PISP/IDS, illnesses were commonly low severity (paraquat=41%; diquat=81%); however, SENSOR/PISP/IDS identified 24 deaths caused by paraquat and 5 deaths associated with diquat. Nineteen paraquat-related deaths were due to ingestion, seven of which were unintentional, often due to improper storage in beverage bottles. In SENSOR/PISP/IDS, paraquat and diquat-related acute illnesses were work-related in 68% (n=203) and 29% (n=42) of cases, respectively. When herbicide application site was known, the vast majority of acute paraquat-related illnesses (81%) arose from agricultural applications. Common root causes of illness were failure to use adequate personal protective equipment (PPE), application equipment failure, and spill/splash of herbicide. Although the magnitude of acute paraquat/diquat-related illnesses was relatively low, several fatalities were identified. Many illnesses could be prevented through stricter compliance with label requirements (e.g. ensuring proper herbicide storage and PPE use), and through enhanced training of certified applicators.

Hypokalemia is not an isolated disease but an associated finding in a number of different diseases. It is also a commonly neglected condition among patients with acute acetaminophen overdose. This study intended to determine the prevalence of hypokalemia and its clinical correlates in acute psychiatric illness among hypokalemic and normokalemic patients after acetaminophen overdose. This is a retrospective cohort study of hospital admissions for acute acetaminophen overdose conducted over a period of 5 years from 1 January 2004 to 31 December 2008. Demographic data and different types of psychiatric illness were compared between hypokalemic and normokalemic patients. Hypokalemia was predefined by a serum concentration <3.5 mmol/L. Statistical Package for Social Sciences (SPSS) 15 was used for data analysis. Two hundred and eighty patients out of 305 admissions were studied. Hypokalemia was found in 63.6% of patients with a higher prevalence in the presence of psychiatric illness (67.7%). Hypokalemic patients were significantly associated with the presence of major depression (p = .04), adjustment disorder (p < .001), anxiety (p = .01), and suicidal attempts (p = .04). Hypokalemia was common among patients with psychiatric illness and acute acetaminophen overdose.

Evidence on the use of paracetamol in febrile children.

2003-01-01

Antipyretics, including acetaminophen (paracetamol), are prescribed commonly in children with pyrexia, despite minimal evidence of a clinical benefit. A literature review was performed by searching Medline and the Cochrane databases for research papers on the efficacy of paracetamol in febrile illnesses in children and adverse outcomes related to the use of paracetamol. No studies showed any clear benefit for the use of paracetamol in therapeutic doses in febrile children with viral or bacterial infections or with malaria. Some studies suggested that fever may have a beneficial role in infection, although no definitive prospective studies in children have been done to prove this. The use of paracetamol in therapeutic doses generally is safe, although hepatotoxicity has occurred with recommended dosages in children. In developing countries where malnutrition is common, data on the safety of paracetamol are lacking. The cost of paracetamol for poor families is substantial. No evidence shows that it is beneficial to treat febrile children with paracetamol. Treatment should be given only to children who are in obvious discomfort and those with conditions known to be painful. The role of paracetamol in children with severe malaria or sepsis and in malnourished, febrile children needs to be clarified. PMID:12856055

Mercury vapour has been shown to cause acute effects on the lung when inhaled in high concentrations. Four men, exposed to mercury inside a tank, developed, hours later, signs and symptoms of an acute febrile illness with severe pulmonary irritation, characterized by fever, rigors, cough, dyspnoea, and tightness in the chest. A review of the literature revealed that this syndrome had been described and investigated previously in fewer than 20 cases during the past 40 years, and is apparently little known. Fatalities have been described, particularly in children, and necropsy evidence has consistently revealed the pattern of an acute diffuse interstitial pneumonitis, accompanied by profuse fibrinous exudation and erosion of the bronchial and bronchiolar lining. The two common features in all reports are the heating of mercury or the entering into a confined space, or both. Adequate respiratory protection by an efficient air-supplied respirator is mandatory in industrial circumstances of the kind described in this report. PMID:5488692

Expatriates ill after travel: Results from the Geosentinel Surveillance Network

PubMed Central

2012-01-01

Background Expatriates are a distinct population at unique risk for health problems related to their travel exposure. Methods We analyzed GeoSentinel data comparing ill returned expatriates with other travelers for demographics, travel characteristics, and proportionate morbidity (PM) for travel-related illness. Results Our study included 2,883 expatriates and 11,910 non-expatriates who visited GeoSentinel clinics ill after travel. Expatriates were more likely to be male, do volunteer work, be long-stay travelers (>6 months), and have sought pre-travel advice. Compared to non-expatriates, expatriates returning from Africa had higher proportionate morbidity (PM) for malaria, filariasis, schistosomiasis, and hepatitis E; expatriates from the Asia-Pacific region had higher PM for strongyloidiasis, depression, and anxiety; expatriates returning from Latin America had higher PM for mononucleosis and ingestion-related infections (giardiasis, brucellosis). Expatriates returning from all three regions had higher PM for latent TB, amebiasis, and gastrointestinal infections (other than acute diarrhea) compared to non-expatriates. When the data were stratified by travel reason, business expatriates had higher PM for febrile systemic illness (malaria and dengue) and vaccine-preventable infections (hepatitis A), and volunteer expatriates had higher PM for parasitic infections. Expatriates overall had higher adjusted odds ratios for latent TB and lower odds ratios for acute diarrhea and dermatologic illness. Conclusions Ill returned expatriates differ from other travelers in travel characteristics and proportionate morbidity for specific diseases, based on the region of exposure and travel reason. They are more likely to present with more serious illness. PMID:23273048

Analysis of a potential trigger of an acute illness.

PubMed

Becker, Niels G; Salim, Agus; Kelman, Christopher W

2006-01-01

Sometimes certain short-term risk exposures are postulated to act as a trigger for the onset of a specific acute illness. When the incidence of the illness is low it is desirable to investigate this possible association using only data on cases detected during a specific observation period. Here we propose an analysis for such a study based on a model expressed in terms of the probability that the exposure triggers the illness and a random delay from a triggered illness until its diagnosis. Both the natural hazard rate for the illness and the probability that the exposure triggers the illness are assumed to be small and possibly dependent on age and covariates such as sex and duration or severity of the exposure. The method of analysis is illustrated with a study of the association between long flights and hospitalization for venous thromboembolism.

In malaria endemic areas, fever has been used as an entry point for presumptive treatment of malaria. At present, the decrease in malaria transmission in Africa implies an increase in febrile illnesses related to other causes among underfives. Moreover, it is estimated that more than half of the children presenting with fever to public clinics in Africa do not have a malaria infection. Thus, for a better management of all febrile illnesses among under-fives, it becomes relevant to understand the underlying aetiology of the illness. The present study was conducted to determine the relative prevalence and predictors of P. falciparum malaria, urinary tract infections and bacteremia among under-fives presenting with a febrile illness at the Makongoro Primary Health Centre, North-Western Tanzania. From February to June 2011, a cross-sectional analytical survey was conducted among febrile children less than five years of age. Demographic and clinical data were collected using a standardized pre-tested questionnaire. Blood and urine culture was done, followed by the identification of isolates using in-house biochemical methods. Susceptibility patterns to commonly used antibiotics were investigated using the disc diffusion method. Giemsa stained thin and thick blood smears were examined for any malaria parasites stages. A total of 231 febrile under-fives were enrolled in the study. Of all the children, 20.3% (47/231, 95%CI, 15.10-25.48), 9.5% (22/231, 95%CI, 5.72-13.28) and 7.4% (17/231, 95%CI, 4.00-10.8) had urinary tract infections, P. falciparum malaria and bacteremia respectively. In general, 11.5% (10/87, 95%CI, 8.10-14.90) of the children had two infections and only one child had all three infections. Predictors of urinary tract infections (UTI) were dysuria (OR = 12.51, 95% CI, 4.28-36.57, P < 0.001) and body temperature (40-41 C) (OR = 12.54, 95% CI, 4.28-36.73, P < 0.001). Predictors of P. falciparum severe malaria were pallor (OR = 4.66 95%CI, 1.21-17.8, P = 0

Febrile status epilepticus can have neurological sequelae. The type of sequelae, however, depend on the etiology, including infection due to viral agents such as the influenza virus. Respiratory syncytial virus (RSV) infection in childhood may also contribute to this. The aim of this study was therefore to characterize febrile status epilepticus associated with RSV infection, and to determine whether this type of infection is a risk factor for neurological sequelae in febrile status epilepticus. We reviewed the medical records of children aged ≤3 years with febrile status epilepticus who were admitted to a tertiary hospital between January 2007 and December 2011. The differences between the RSV-positive and RSV-negative groups were evaluated according to the demographic and clinical data. A total of 99 patients with febrile status epilepticus who had been tested for RSV infection were identified. Three patients in the RSV-positive group (n = 19) and four in the RSV-negative group (n = 80) presented with bronchiolitis. The incidence of intubation and anti-seizure drug treatment in the RSV-positive group was significantly higher than in the -negative group. While all of the patients in the RSV-negative group recovered completely, six patients in the RSV-positive group developed encephalopathy and profound neurological sequelae. In five of the six patients, diffusion-weighted magnetic resonance imaging showed subcortical white matter lesions. RSV infection in the absence of bronchiolitis can initially present as febrile status epilepticus and subsequently develop into acute encephalopathy with profound neurological sequelae. © 2017 Japan Pediatric Society.

The goal of this study was to examine preferences for shared decision-making (SDM) in parents of acutely ill versus chronically ill children in the inpatient setting. Additionally, we explored the effect of parental perception of illness severity and uncertainty in illness on decision-making preference. In this cross-sectional study, we surveyed parents of children admitted to pediatric inpatient units at an academic, tertiary-care hospital. Surveys were administered in person and used validated tools to assess SDM preferences and uncertainty in illness. Descriptive statistics evaluated associations stratified by acute versus chronic illness, and multivariable analyses were performed. Of the 200 parents who participated, the majority were women (78%), Hispanic (81.5%), English speaking (73%), between 30 and 39 years old (37.5%), and had an education achievement of less than a college degree (77%). The mean age of hospitalized children was 8.1 years, and half reported a chronic illness. Most parents preferred an active (43%) or collaborative (40%) role in SDM. There was no association with SDM preference by demographics, number of previous hospitalizations, perception of illness severity, or uncertainty. However, parents of chronically ill children significantly preferred a passive role in SDM when they perceived a high level of uncertainty in illness. Most parents of hospitalized children prefer to take an active or collaborative role in SDM. However, parents of chronically ill children who perceive high levels of uncertainty surrounding their children's illness prefer a passive role, thus illustrating the complexity in decision-making among this parent population.

The global euthanasia debate by health care professionals has raised important ethical issues concerning the professional duties and responsibilities of nurses caring for terminal patients. The purpose of this study was to examine the attitudes of acutely ill patients towards the practice of euthanasia in Hong Kong. A modified form of the 23-item Questionnaire for General Household Survey scale was used. This cross-sectional survey study was conducted with a stratified sample of in-patients recruited from a wide variety of departments in a regional, acute general hospital. Seventy-seven out of 129 patients responded (59.7%) and a high proportion of patients agreed with the use of euthanasia in the following circumstances: ‘where they were a third party’, if ‘someone they loved’ was affected, or if ‘they themselves were the patient’. Of the 77 patients, 54 agreed with active euthanasia (70.1%) and 65 with passive (84.4%). The results also indicated that a few socio-demographic characteristics (such as age, gender and household income) statistically significantly correlated with patients’ attitudes towards euthanasia. These findings highlight that Chinese patients with acute illness generally accept the use of euthanasia. Further research on the attitudes and perceptions of patients towards the use of euthanasia is recommended, particularly in diverse groups of Chinese and Asian patients with acute or terminal illness.

To determine patient preferences for information and for participation in decision-making, and the determinants of these preferences in patients recently admitted to an acute hospital. Prospective questionnaire-based study. Medical wards of an acute teaching hospital. One hundred and fifty-two consecutive acute medical inpatients, median age 74 years. Standardised assessment included abbreviated mental test and subjective measure of severity of illness. Patients' desire for information was assessed using a 5-point Likert scale, and their desire for a role in medical decision-making using the Degner Control of Preferences Scale. Of the 152 patients, 93 (61%) favoured a passive approach to decision-making (either "leave all decisions to the doctor" or "doctor makes final decision but seriously considers my opinion." In contrast, 101 (66%) patients sought "very extensive" or "a lot" of information about their condition. No significant effects of age, sex, socio-economic group or severity of acute illness on desire for information or the Degner scale result were found. There was no agreement between patients' preferences on the Degner scale and their doctors' predictions of those preferences. Acute medical inpatients want to receive a lot of information about their illness, but most prefer a relatively passive role in decision-making. The only way to determine individual patient preferences is to ask them; preferences cannot be predicted from clinical or sociodemographic data.

Children with care for acute illness available through the Health-e-Access telemedicine model at childcare and schools were previously found to have 22% less emergency department (ED) use than counterparts without this service, but they also had 24% greater acute care use overall. We assessed the hypothesis that increased utilization reflected improved access among impoverished inner-city children to a level experienced by more affluent suburban children. This observational study compared utilization among children without and with telemedicine access, beginning in 1993, ending in 2007, and based on 84,287 child-months of billing claims-based observation. Health-e-Access Telemedicine was initiated in stepwise manner over 187 study-months among 74 access sites (childcare, schools, community centers), beginning in month 105. Children dwelled in inner city, rest-of-city Rochester, NY, or in surrounding suburbs. Rate of total acute care visits (office, ED, telemedicine) was measured as visits per 100 child-years. Observed utilization rates were adjusted in multivariate analysis for age, sex, insurance type, and season of year. When both suburban and inner-city children lacked telemedicine access, overall acute illness visits were 75% greater among suburban than inner-city children (suburban:inner-city rate ratio 1.75, p < 0.0001). After telemedicine became available to inner-city children, their overall acute visits approximated those of suburban children (suburban:inner-city rate ratio 0.80, p = 0.07), whereas acute visits among suburban children remained at least (worst-case comparison) 56% greater than inner-city children without telemedicine (rate ratio 1.56, p < 0.0001). At baseline, overall acute illness utilization of suburban children exceeded that of inner-city children. Overall utilization for inner-city children increased with telemedicine to that of suburban children at baseline. Without telemedicine, however, inner-city use remained

Introduction Older adults use the emergency department (ED) at high rates, including for illnesses that could be managed by their primary care providers (PCP). Policymakers have implemented barriers and incentives, often financial, to try to modify use patterns but with limited success. This study aims to understand the factors that influence older adults’ decision to obtain acute illness care from the ED rather than from their PCPs. Methods We performed a qualitative study using a directed content analysis approach from February to October 2013. Fifteen community-dwelling older adults age≥65 years who presented to the ED of an academic medical center hospital for care and who were discharged home were enrolled. Semi-structured interviews were conducted initially in the ED and subsequently in patients’ homes over the following six weeks. All interviews were audio-recorded, transcribed, verified, and coded. The study team jointly analyzed the data and identified themes that emerged from the interviews. Results The average age of study participants was 74 years (standard deviation ±7.2 years); 53% were female; 80% were white. We found five themes that influenced participants’ decisions to obtain acute illness care from the ED: limited availability of PCP-based care, variable interactions with healthcare providers and systems, limited availability of transportation for illness care, desire to avoid burdening friends and family, and previous experiences with illnesses. Conclusion Community-dwelling older adults integrate multiple factors when deciding to obtain care from an ED rather than their PCPs. These factors relate to personal and social considerations, practical issues, and individual perceptions based on previous experiences. If these findings are validated in confirmatory studies, policymakers wishing to modify where older adults receive care should consider person-centered interventions at the system and individual level, such as decision support

Hyperthermia produces neural tube defects (NTDs) in a variety of animal species. Elevated maternal body temperatures may also place the developing human embryo at risk. We examined the relation between maternal hyperthermia and the development of NTDs in a high-risk Mexican-American population. Case-women were Mexican-American women with NTD-affected pregnancies who resided and delivered in any of the 14 Texas counties bordering Mexico, during 1995-2000. Control-women were randomly selected from study area residents delivering normal live births, frequency-matched to cases by hospital and year. Information on maternal fevers, febrile illnesses, exposures to heat generated from external sources, and hyperthermia-inducing activities was gathered through in-person interviews, conducted about six weeks postpartum. The risk effect (OR) associated with maternal fever in the first trimester, compared to no fever, was 2.9 (95% CI, 1.5-5.7). Women taking fever-reducing medications showed a lower risk effect (OR, 2.4; 95% CI, 1.0-5.6) than those who did not (OR, 3.8; 95% CI, 1.4-10.9). First-trimester maternal exposures to heat devices such as hot tubs, saunas, or electric blankets were associated with an OR of 3.6 (95% CI, 1.1-15.9). Small insignificant effects were observed for activities such as cooking in a hot kitchen (OR, 1.6; 95% CI, 1.0-2.6) and working or exercising in the sun (OR, 1.4; 95% CI, 0.9-2.2). Maternal hyperthermia increases the risk for NTD-affected offspring. Women intending to become pregnant should avoid intense heat exposures, carefully monitor and manage their febrile illnesses, and routinely consume folic acid supplements. (c) 2004 Wiley-Liss, Inc.

The Sentinel Event Theory provides a stepwise approach for building models to understand how negative events can spark health behavior change. This study tested a preliminary model using the Sentinel Events Method in a sample (N = 300) of smokers who sought care for acute cardiac symptoms. Patients completed measures on: smoking-related causal attribution, perceived severity of the acute illness event, illness-related fear, and intentions to quit smoking. Patients were followed up one week after the health event and a 7 day time line follow back (TLFB) was completed to determine abstinence from tobacco. Structural equation models were performed using average predictor scale scores at baseline, as well as three different time anchors for ratings of illness severity and illness-related fear. Quit intentions, actual illness severity, and age were consistent, positive, independent predictors of 7 day point prevalence abstinence. Additional research on the influences of perceptions and emotional reactions is warranted. PMID:25563437

Toxoplasmosis is one of the most common human zoonosis, and is generally benign in most of the individuals. Pulmonary involvement is common in immunocompromised subjects, but very rare in immunocompetents and there are scarce reports of tomographic findings in the literature. The aim of the study is to describe three immunocompetent patients diagnosed with acute pulmonary toxoplasmosis and their respective thoracic tomographic findings. Acute toxoplasmosis was diagnosed according to the results of serological tests suggestive of recent primary infection and the absence of an alternative etiology. From 2009 to 2013, three patients were diagnosed with acute respiratory failure secondary to acute toxoplasmosis. The patients were two female and one male, and were 38, 56 and 36 years old. Similarly they presented a two-week febrile illness and progressive dyspnea before admission. Laboratory tests demonstrated lymphocytosis, slight changes in liver enzymes and high inflammatory markers. Tomographic findings were bilateral smooth septal and peribronchovascular thickening (100%), ground-glass opacities (100%), atelectasis (33%), random nodules (33%), lymph node enlargement (33%) and pleural effusion (66%). All the patients improved their symptoms after treatment, and complete resolution of tomographic findings were found in the followup. These cases provide a unique description of the presentation and evolution of pulmonary tomographic manifestations of toxoplasmosis in immunocompetent patients. Toxoplasma pneumonia manifests with fever, dyspnea and a non-productive cough that may result in respiratory failure. In animal models, changes were described as interstitial pneumonitis with focal infiltrates of neutrophils that can finally evolve into a pattern of diffuse alveolar damage with focal necrosis. The tomographic findings are characterized as ground glass opacities, smooth septal and marked peribronchovascular thickening; and may mimic pulmonary congestion

Introduction: Given the complexity of biological systems, understanding their dynamic behaviors, such as the Acute Inflammatory Response (AIR), requires a formal synthetic process. Dynamic Mathematical Modeling (DMM) represents a suite of methods intended for inclusion within the required synthetic framework. DMM, however, is a relatively novel approach in the practice of biomedical research. The Society for Complexity in Acute Illness (SCAI) was formed in 2004 from the leading research groups utilizing DMM in the study of acute inflammation. This Society believes that it is important to offer guidelines for the design, development and utilization of DMM in the setting of AIR research to avoid the “garbage-in garbage-out” problem. Accordingly, SCAI identified a need for and carried out a critical appraisal of DMM as currently used in the setting of acute illness. Methods: The SCAI annual meeting in 2005, the 4th International Conference on Complexity in Acute Illness (ICCAI; Cologne, Germany), was structured with the intent of developing a consensus statement on the methods and execution of DMM in AIR research. The conference was organized to include a series of interactive breakout sessions that included thought leaders from both the DMM and acute illness fields, the results of which were then presented in summary form to the entire group for discussion and consensus. The information in this manuscript represents the concatenation of those presentations. Results: The output from the 4th ICCAI involved consensus statements for the following topics: 1) the need for DMM, 2) a suggested approach for the process of establishing a modeling project, 3) the type of “wet” lab experiments and data needed to establish a modeling project, 4) general quality measures for data to be input to a modeling project, and 5) a descriptive list of several types of DMM to provide guidance in selection of a method for a project. Conclusion: We believe that the complexity of

Prevalence and predictors of urinary tract infection and severe malaria among febrile children attending Makongoro health centre in Mwanza city, North-Western Tanzania

Background In malaria endemic areas, fever has been used as an entry point for presumptive treatment of malaria. At present, the decrease in malaria transmission in Africa implies an increase in febrile illnesses related to other causes among underfives. Moreover, it is estimated that more than half of the children presenting with fever to public clinics in Africa do not have a malaria infection. Thus, for a better management of all febrile illnesses among under-fives, it becomes relevant to understand the underlying aetiology of the illness. The present study was conducted to determine the relative prevalence and predictors of P. falciparum malaria, urinary tract infections and bacteremia among under-fives presenting with a febrile illness at the Makongoro Primary Health Centre, North-Western Tanzania. Methods From February to June 2011, a cross-sectional analytical survey was conducted among febrile children less than five years of age. Demographic and clinical data were collected using a standardized pre-tested questionnaire. Blood and urine culture was done, followed by the identification of isolates using in-house biochemical methods. Susceptibility patterns to commonly used antibiotics were investigated using the disc diffusion method. Giemsa stained thin and thick blood smears were examined for any malaria parasites stages. Results A total of 231 febrile under-fives were enrolled in the study. Of all the children, 20.3% (47/231, 95%CI, 15.10-25.48), 9.5% (22/231, 95%CI, 5.72-13.28) and 7.4% (17/231, 95%CI, 4.00-10.8) had urinary tract infections, P. falciparum malaria and bacteremia respectively. In general, 11.5% (10/87, 95%CI, 8.10-14.90) of the children had two infections and only one child had all three infections. Predictors of urinary tract infections (UTI) were dysuria (OR = 12.51, 95% CI, 4.28-36.57, P < 0.001) and body temperature (40-41 C) (OR = 12.54, 95% CI, 4.28-36.73, P < 0.001). Predictors of P. falciparum severe malaria were pallor (OR = 4

An 8-½ year old boy with glutaric aciduria type I (GA1) and chronic dystonia presented with severe rhabdomyolysis in association with a febrile illness. His clinical course was complicated by acute renal failure, cardiac arrest and hypoxic ischemic encephalopathy. As acute neurological decompensation is typically not seen in patients with GA1 beyond early childhood, this case report serves as an important reminder that patients with GA1 and status dystonicus may be at risk for acute life-threatening rhabdomyolysis, renal failure and further neurological injury at any age.

Investigating older acutely ill hospitalized patients' nursing needs and quality of care is paramount, given the growing pressure on nurses to provide increasingly intensive levels of care to a growing older population while at the same time working with reduced staffing levels. The aims of this study were to determine: (1) important aspects of nursing care as perceived by older patients, their family member/carer who observed care during hospitalization, and nurses; (2) satisfaction levels of patients, family/carers and nurses on nursing care received; and (3) mismatches between nursing care priorities and satisfaction with nursing care. Two hundred and thirty-two acutely ill patients aged over 65 years, 99 carers/family members and 90 nurses completed the Caregiving Activities Survey, which measures importance of and satisfaction with various aspects of nursing care. Qualitative data, which qualified responses to survey items, were also obtained from participants. Patients, carers and nurses perceived that carrying out doctors' orders was the most important aspect of nursing care, followed by physical care, psychosocial care and discharge planning. Nurses and carers rated physical care, psychosocial care and discharge planning more highly than patients. Physical care was rated highly by patients in terms of importance, but rated moderately in terms of satisfaction. Carers' and patients' ratings of satisfaction with physical care were lower than nurses' ratings of opportunities to provide it. The importance of discharge planning was rated highly by nurses but all groups were only moderately satisfied with this aspect of care. The findings do not apply to acutely ill older patients with confusion, mental illness or more than early stage dementia. Patients, nurses and family/carers were generally in agreement about the relative importance of particular aspects of nursing care. Nurses may need to communicate more effectively with older patients and their family

As part of a virus discovery investigation using a metagenomic approach, a highly divergent novel Human papillomavirus type was identified in pooled convenience nasal/oropharyngeal swab samples collected from patients with febrile respiratory illness. Phylogenetic analysis of the whole genome and the L1 gene reveals that the new HPV identified in this study clusters with previously described gamma papillomaviruses, sharing only 61.1% (whole genome) and 63.1% (L1) sequence identity with its closest relative in the Papillomavirus episteme (PAVE) database. This new virus was named HPV_SD2 pending official classification. The complete genome of HPV-SD2 is 7,299 bp long (36.3% G/C) and contains 7 open reading frames (L2, L1, E6, E7, E1, E2 and E4) and a non-coding long control region (LCR) between L1 and E6. The metagenomic procedures, coupled with the bioinformatic methods described herein are well suited to detect small circular genomes such as those of human papillomaviruses. PMID:23554892

Illness representation after acute myocardial infarction: impact on in-hospital recovery.

Despite significant progress in the treatment of coronary artery disease, myocardial infarction is still the leading cause of death in the United States. As suggested by Leventhal's Self-Regulation Model of Illness, the continued high morbidity and mortality may be due to a failure to address the role of psychosocial factors such as illness representation, depression, and anxiety in recovery. To determine the relationship between illness representation of myocardial infarction and the occurrence of in-hospital complications and if anxiety and depression mediate this relationship. A prospective correlational design was used to measure illness representation, depression, and anxiety 24 to 48 hours after admission for myocardial infarction in 49 patients and the frequency of complications during the acute event. Logistic regression was used to determine the likelihood of experiencing a complication. When demographic and clinical variables were controlled for, the more negative the representation of illness, the greater were the odds of experiencing a complication (chi2 = 16.9, df = 6, P =.01). The odds of experiencing a complication increased 5.1% for each 1 unit increase in the score on the Illness Preparation Questionnaire (B = 0.05, Wald = 4.442, Exp(B) = 1.051, 95% CI = 1.003-1.1010). Neither anxiety (chi2 = 3.0, df = 1, P =. 09) nor depression (chi2 = 2.5, df = 1, P = .11) were significant predictors of the occurrence of complications. In these patients, illness representation was predictive of the likelihood of experiencing a complication. Thus, illness representation appears to be an important psychosocial factor in acute recovery from myocardial infarction.

Q fever in Kenya is poorly reported and its surveillance is highly neglected. Standard empiric treatment for febrile patients admitted to hospitals is antimalarials or penicillin-based antibiotics, which have no activity against Coxiella burnetii. This study aimed to assess the seroprevalence and the predisposing risk factors for Q fever infection in febrile patients from a pastoralist population, and derive a model for clinical prediction of febrile patients with acute Q fever. Epidemiological and clinical data were obtained from 1067 patients from Northeastern Kenya and their sera tested for IgG antibodies against Coxiella burnetii antigens by enzyme-linked-immunosorbent assay (ELISA), indirect immunofluorescence assay (IFA) and quantitative real-time PCR (qPCR). Logit models were built for risk factor analysis, and diagnostic prediction score generated and validated in two separate cohorts of patients. Overall 204 (19.1 %, 95 % CI: 16.8-21.6) sera were positive for IgG antibodies against phase I and/or phase II antigens or Coxiella burnetii IS1111 by qPCR. Acute Q fever was established in 173 (16.2 %, 95 % CI: 14.1-18.7) patients. Q fever was not suspected by the treating clinicians in any of those patients, instead working diagnosis was fever of unknown origin or common tropical fevers. Exposure to cattle (adjusted odds ratio [aOR]: 2.09, 95 % CI: 1.73-5.98), goats (aOR: 3.74, 95 % CI: 2.52-9.40), and animal slaughter (aOR: 1.78, 95 % CI: 1.09-2.91) were significant risk factors. Consumption of unpasteurized cattle milk (aOR: 2.49, 95 % CI: 1.48-4.21) and locally fermented milk products (aOR: 1.66, 95 % CI: 1.19-4.37) were dietary factors associated with seropositivity. Based on regression coefficients, we calculated a diagnostic score with a sensitivity 93.1 % and specificity 76.1 % at cut off value of 2.90: fever >14 days (+3.6), abdominal pain (+0.8), respiratory tract infection (+1.0) and diarrhoea (-1.1).

We assessed the role of therapeutic delay time (TDT) in acute renal cortical scintigraphic lesion (ASL) and ultimate scar formation (USF) in children with first febrile UTI and whether it is affected by the presence of vesico-ureteral reflux (VUR). 230 children, 90 girls and 140 boys with first febrile UTI were included. Radiologic (USG, DMSA, and VCUG), clinical (age, gender, peak fever, therapeutic delay time) and laboratory (CBC with differential count, ANC (absolute neutrophil count), BUN, Creatinine, urine analysis, gram stain, culture, CRP and ESR) variables were analysed. DMSA was performed within 5 days and after six months. VCUG was performed after acute phase of UTI. The differences in TDT according to the presence of ASL, USF and VUR were assessed. And the correlation between ASL or USF with the duration of TDT was assessed. Of 230 patients enrolled, 142 patients had refluxing UTI and 88 patients had non-refluxing UTI. TDT was the risk factor associated with ASL and USF along with presence of VUR. TDT was longer in ASL positive group compared with the ASL negative group. Also USF group showed longer TDT compared with those without USF in both refluxing UTI and non refluxing UTI. The TDT was significantly shorter in USF group with the presence of VUR. Positive linear association was noted between prevalence of ASL and USF and duration of TDT. In conclusion, the impact of UTI on formation of USF may be enhanced by the presence of VUR with shorter duration of TDT.

Respiratory infections and acute lung injury in systemic illness.

We have discussed the relationship between systemic illness, infection, and lung disease. As we have seen, patients with a wide variety of disease states, including advanced age, diabetes mellitus, alcoholism, collagen vascular disease, cancer, heart failure, and organ transplantation are potentially at increased risk for pneumonia because of disease-related impairments in host defenses. In addition, two virtually ubiquitous conditions in hospitalized patients, malnutrition and therapeutic interventions (especially with common medications), frequently add to the risk of airway invasion by bacterial pathogens. Systemic illness not only makes lung infection more common, but may adversely affect outcome and resolution, as well as determine the clinical presentation of pneumonia. In one particular population, the intubated and mechanically ventilated patient, the risk of infection is particularly high, and nosocomial pneumonia is a major cause of mortality. To the extent that the host response itself leads to the symptoms and signs of infection, systemically ill individuals may have subtle clinical features when serious bacterial invasion is present. Many components of the host defense system can become abnormal with serious illness, but a common mechanism that ties many systemic diseases to pneumonia is an alteration in airway epithelial cell receptivity for bacteria, namely, bacterial adherence, a process that mediates airway colonization, the first pathogenetic step on the road to pneumonia. The impetus for understanding how serious illness promotes lung infection is that once these mechanisms are identified, potential preventative strategies to minimize infection risk in the individual with systemic disease may be developed. The relationship among systemic illness, the lung, and infection also exists in a different direction: infection of a systemic nature (the septic syndrome) can lead to disease in the lung (ARDS). We have described the features of the septic

To compare rapid diagnostic tests (RDTs) for malaria with routine microscopy in guiding treatment decisions for febrile patients. Randomised trial. Outpatient departments in northeast Tanzania at varying levels of malaria transmission. 2416 patients for whom a malaria test was requested. Staff received training on rapid diagnostic tests; patients sent for malaria tests were randomised to rapid diagnostic test or routine microscopy Proportion of patients with a negative test prescribed an antimalarial drug. Of 7589 outpatient consultations, 2425 (32%) had a malaria test requested. Of 1204 patients randomised to microscopy, 1030 (86%) tested negative for malaria; 523 (51%) of these were treated with an antimalarial drug. Of 1193 patients randomised to rapid diagnostic test, 1005 (84%) tested negative; 540 (54%) of these were treated for malaria (odds ratio 1.13, 95% confidence interval 0.95 to 1.34; P=0.18). Children aged under 5 with negative rapid diagnostic tests were more likely to be prescribed an antimalarial drug than were those with negative slides (P=0.003). Patients with a negative test by any method were more likely to be prescribed an antibiotic (odds ratio 6.42, 4.72 to 8.75; P<0.001). More than 90% of prescriptions for antimalarial drugs in low-moderate transmission settings were for patients for whom a test requested by a clinician was negative for malaria. Although many cases of malaria are missed outside the formal sector, within it malaria is massively over-diagnosed. This threatens the sustainability of deployment of artemisinin combination treatment, and treatable bacterial diseases are likely to be missed. Use of rapid diagnostic tests, with basic training for clinical staff, did not in itself lead to any reduction in over-treatment for malaria. Interventions to improve clinicians' management of febrile illness are essential but will not be easy. Clinical trials NCT00146796 [ClinicalTrials.gov].

Emergency department (ED) visits for acute alcohol intoxication are common, but this population is at risk for decompensation and occult critical illness. The purpose of this study is to describe the incidence and predictors of unsuspected critical illness among patients with acute alcohol intoxication. This was a retrospective observational study of ED patients from 2011 to 2016 with acute alcohol intoxication. The study cohort included patients presenting for alcohol intoxication, whose initial assessment was uncomplicated alcohol intoxication without any other active acute medical or traumatic complaints. The primary outcome was defined as the unanticipated subsequent use of critical care resources during the encounter or admission to an ICU. We investigated potential predictors for this outcome with generalized estimating equations. We identified 31,364 eligible patient encounters (median age 38 years; 71% men; median breath alcohol concentration 234 mg/dL); 325 encounters (1%) used critical care resources. The most common diagnoses per 1,000 ED encounters were acute hypoxic respiratory failure (3.1), alcohol withdrawal (1.7), sepsis or infection (1.1), and intracranial hemorrhage (1.0). Three patients sustained a cardiac arrest. Presence of the following had an increased adjusted odds ratio (aOR) of developing critical illness: hypoglycemia (aOR 9.2), hypotension (aOR 3.8), tachycardia (aOR 1.8), fever (aOR 7.6), hypoxia (aOR 3.8), hypothermia (aOR 4.2), and parenteral sedation (aOR 2.4). The initial blood alcohol concentration aOR was 1.0. Critical care resources were used for 1% of ED patients with alcohol intoxication who were initially assessed by physicians to have low risk. Abnormal vital signs, hypoglycemia, and chemical sedation were associated with increased odds of critical illness. Copyright © 2017 American College of Emergency Physicians.

In Africa, malaria is responsible for 25-40% of all outpatient visits and 20-50% of all hospitalizations. In malaria-endemic areas, individuals do not behave the same toward the outcome of clinical malaria. The aim of this study is to determine the prevalence of malaria in the locality among the different ethnic groups, evaluate the place of malaria among febrile illnesses, and assess the relationship between fever and parasite density of Plasmodium falciparum. Studies on susceptibility to malaria between the Fulani and Dogon groups in Mali were conducted in Mantéourou and the surrounding villages from 1998 to 2008. We carried out six cross-sectional studies during the malaria transmission and longitudinal surveys (July to December depending on the year) during the 10-year duration. In longitudinal studies, clinical data on malaria and other diseases frequently observed in the population were recorded. It appears from this work that malaria is the leading cause of febrile syndromes. We observed a significant reduction in malaria morbidity in the study population from 1998 to 2008. The pyrogenic threshold of parasitaemia was 1,000 parasites/mm(3) of blood in the Dogon and 5,000 parasites/mm(3) of blood in the Fulani.We have also found that high parasitical densities were not always associated with fever. Malaria morbidity was higher among the Dogon than in Fulani. The immunogenetic factors might account for this difference in susceptibility to malaria between Fulani and Dogon in the area under study. With regard to this study, it is important to take into account the ethnic origin of subjects when interpreting data of clinical and malarial vaccine trials.

Febrile neutropenia which is a common complication of cancer treatment, is one of the major causes of morbidity and mortality. Several gram-negative and gram-positive bacteria are responsible for infections in neutropenic patients, however the most common microorganisms are Escherichia coli and coagulase-negative staphylococci, in decreasing order. Although Brucella spp. infections are endemic in Turkey, brucellosis-related febrile neutropenia has only rarely been reported. In this report, a case of brucellosis-related febrile neutropenia in a patient with acute myeloblastic leukemia (AML) was presented. A 56-year-old male patient presenting with fever, petechiae/purpura, leukocytosis, thrombocytopenia, and anemia was admitted to our hospital. Laboratory studies revealed a hemoglobin level of 8.27 g/dl, leukocyte count of 77.100 k/ml, absolute neutrophil count of 200 k/ml, and platelets at 94.200 k/ml. The patient was diagnosed as AML-M1 and piperacillin/tazobactam was started as the first-line antibiotic therapy due to the febrile neutropenia. On admission, blood and urine cultures were negative. Once the fever was controlled, remission/induction chemotherapy was initiated. However, fever developed again on the eight day, and vancomycin was added to the therapy. Since the fever persisted, the antibiotic therapy was gradually replaced with meropenem and linezolid. However, fever continued and the patient's general condition deteriorated. Subsequently performed Brucella tube agglutination test revealed positivity at 1/320 titer and the microorganism grown in blood culture (Bactec 9050; BD, USA) was identified as B.melitensis by conventional methods. Rifampicin and doxycycline therapy was started immediately, however, the patient died due to septic shock. If the tests for brucellosis were performed earlier when response to second step antibiotic therapy lacked in this patient, it was assumed that mortality could be prevented by the prompt initiation of the

High-intensity regimes of chemotherapy have led to longer and more severe episodes of neutropenia with a resulting increase in morbidity and mortality due to infections. Which empiric antibiotic regimen to use in these cases is still under debate. We performed a randomized comparative study to evaluate the efficacy of cefepime versus ceftriaxone plus amikacin as the initial treatment in an escalating, empirical, antibiotic therapy regimen in febrile neutropenic patients. Both adults and children were included. All patients had less than 500 neutrophils/microl at the time of infection. Patients were randomized to receive either cefepime or ceftriaxone plus amikacin. If infection continued 72 h later, patients in both groups received vancomycin, and if infection had not disappeared 7 days after starting antibiotics, amphotericin B was started. Twenty patients were included in each group. Both treatment and control groups were comparable for age and sex, among other factors. There were 18 cures in the cefepime group and 17 in the ceftriaxone plus amikacin group (p = 0.9). No patient discontinued therapy because of toxicity. Cefepime is a safe and very effective therapy for patients with acute leukemia and febrile neutropenia; in addition, it is a cheaper regimen in our country, and lacks the potential toxicity of the aminoglycosides.

Pre-existing psychiatric illness, illicit drug use, and alcohol abuse adversely impact patients with orthopaedic trauma injuries. Obesity is an independent factor associated with poorer clinical outcomes and discharge disposition, and higher hospital resource use. It is not known whether interactions exist between pre-existing illness, illicit drug use and obesity on acute trauma care outcomes. This cohort study is from orthopaedic trauma patients prospectively measured over 10 years (N = 6353). Psychiatric illness, illicit drug use and alcohol were classified by presence or absence. Body mass index (BMI) was analyzed as both a continuous and categorical measure (<30 kg/m 2 [non-obese], 30-39.9 kg/m 2 [obese] and ≥40 kg/m 2 [morbidly obese]). Main outcomes were the number of acute care services provided, length of stay (LOS), discharge home, hospital readmissions, and mortality in the hospital. Statistically significant BMI by pre-existing condition (psychiatric illness, illicit drug use) interactions existed for LOS and number of acute care services provided (β values 0.012-0.098; all p < 0.05). The interaction between BMI and psychiatric illness was statistically significant for discharge to locations other than home (β = 0.023; p = 0.001). Obese patients with orthopaedic trauma, particularly with preexisting mental health conditions, will require more hospital resources and longer care than patients without psychiatric illness. Early identification of these patients through screening for psychiatric illness and history of illicit drug use at admission is imperative to mobilize the resources and provide psychosocial support to facilitate the recovery trajectory of affected obese patients.

Frequent infections contribute to childhood stunting in developing countries but the causal pathways are uncertain. We tested the hypothesis that intercurrent illnesses suppress the growth hormone axis through reductions in insulin-like growth factor 1 (IGF-1). In a birth cohort of 202 HIV-unexposed Zimbabwean infants, we analyzed data on 7-day illness recall and measured plasma interleukin-6, C-reactive protein, alpha-1-acid glycoprotein, and IGF-1 by enzyme-linked immunosorbent assay, at age 6 weeks, and then 3, 6, 12, and 18 months. Children with recent acute illness had lower IGF-1 concentrations than healthy children and IGF-1 correlated inversely (P < 0.05) with inflammatory biomarkers at most time points between 3 and 18 months. Using path analysis, we showed that cough and fever had a predominantly indirect effect on suppressing IGF-1, through the acute-phase response, whereas diarrhea had a predominantly direct effect on IGF-1. Acute illness may therefore impact the growth hormone axis through both direct and indirect pathways. PMID:25535308

Background Innovative strategies are needed to tackle childhood mortality in the rural tropics. Artesunate suppositories were developed to bring emergency treatment closer to severely ill children with malaria in rural areas where injectable treatment is not possible for several hours. Adding an antibacterial rectal drug would extend this strategy to treat non-malarial febrile illness as well. The objective of these studies was to assess acceptability of such a new pre-referral strategy by healthcare providers and likely uptake by the population. Methods Two qualitative studies were conducted between May and July 2009. Study 1 investigated the acceptability of introducing a combined antimalarial-antibacterial suppository by interviewing 27 representatives of the three administrative levels (central government, regional, local) of the health sector; Study 2 investigated treatment-seeking behaviour and acceptability of this intervention at community level by interviewing 74 mothers in 2 villages. Results and Conclusions Up to 92% of health representatives were in favour of introducing a new pre-referral strategy to tackle both malaria and non-malaria related severe illnesses in Guinea-Bissau, provided it was endorsed by international health authorities. The main obstacles to implementation were the very limited human and financial resources. In the two villages surveyed, 44% of the mothers associated severe illness with fever only, or fever plus one additional symptom. Mothers’ judgement of severity and ensuing decisions were not specific for serious illness, indicating that initial training to recognize signs of severe disease and treatment availability for non-severe, fever-associated symptoms will be required to prevent overuse of a new intervention designed as a pre-referral treatment for severely ill children. Level C health centres were the first resort in both villages (50% and 87% of respondents respectively). This information is encouraging for the

Acute kidney injury frequently complicates critical illness and is associated with high morbidity and mortality. Frailty is common in critical illness survivors, but little is known about the impact of acute kidney injury. We examined the association of acute kidney injury and frailty within a year of hospital discharge in survivors of critical illness. Secondary analysis of a prospective cohort study. Medical/surgical ICU of a U.S. tertiary care medical center. Three hundred seventeen participants with respiratory failure and/or shock. None. Acute kidney injury was determined using Kidney Disease Improving Global Outcomes stages. Clinical frailty status was determined using the Clinical Frailty Scale at 3 and 12 months following discharge. Covariates included mean ICU Sequential Organ Failure Assessment score and Acute Physiology and Chronic Health Evaluation II score as well as baseline comorbidity (i.e., Charlson Comorbidity Index), kidney function, and Clinical Frailty Scale score. Of 317 patients, 243 (77%) had acute kidney injury and one in four patients with acute kidney injury was frail at baseline. In adjusted models, acute kidney injury stages 1, 2, and 3 were associated with higher frailty scores at 3 months (odds ratio, 1.92; 95% CI, 1.14-3.24; odds ratio, 2.40; 95% CI, 1.31-4.42; and odds ratio, 4.41; 95% CI, 2.20-8.82, respectively). At 12 months, a similar association of acute kidney injury stages 1, 2, and 3 and higher Clinical Frailty Scale score was noted (odds ratio, 1.87; 95% CI, 1.11-3.14; odds ratio, 1.81; 95% CI, 0.94-3.48; and odds ratio, 2.76; 95% CI, 1.34-5.66, respectively). In supplemental and sensitivity analyses, analogous patterns of association were observed. Acute kidney injury in survivors of critical illness predicted worse frailty status 3 and 12 months postdischarge. These findings have important implications on clinical decision making among acute kidney injury survivors and underscore the need to understand the drivers of

Abstract Rainstorms increase levels of fecal indicator bacteria in urban coastal waters, but it is unknown whether exposure to seawater after rainstorms increases rates of acute illness. Our objective was to provide the first estimates of rates of acute illness after seawater exposure during both dry- and wet-weather periods and to determine the relationship between levels of indicator bacteria and illness among surfers, a population with a high potential for exposure after rain. We enrolled 654 surfers in San Diego, California, and followed them longitudinally during the 2013–2014 and 2014–2015 winters (33,377 days of observation, 10,081 surf sessions). We measured daily surf activities and illness symptoms (gastrointestinal illness, sinus infections, ear infections, infected wounds). Compared with no exposure, exposure to seawater during dry weather increased incidence rates of all outcomes (e.g., for earache or infection, adjusted incidence rate ratio (IRR) = 1.86, 95% confidence interval (CI): 1.27, 2.71; for infected wounds, IRR = 3.04, 95% CI: 1.54, 5.98); exposure during wet weather further increased rates (e.g., for earache or infection, IRR = 3.28, 95% CI: 1.95, 5.51; for infected wounds, IRR = 4.96, 95% CI: 2.18, 11.29). Fecal indicator bacteria measured in seawater (Enterococcus species, fecal coliforms, total coliforms) were strongly associated with incident illness only during wet weather. Urban coastal seawater exposure increases the incidence rates of many acute illnesses among surfers, with higher incidence rates after rainstorms. PMID:28498895

The management of childhood infections remains inadequate in resource-limited countries, resulting in high mortality and irrational use of antimicrobials. Current disease management tools, such as the Integrated Management of Childhood Illness (IMCI) algorithm, rely solely on clinical signs and have not made use of available point-of-care tests (POCTs) that can help to identify children with severe infections and children in need of antibiotic treatment. e-POCT is a novel electronic algorithm based on current evidence; it guides clinicians through the entire consultation and recommends treatment based on a few clinical signs and POCT results, some performed in all patients (malaria rapid diagnostic test, hemoglobin, oximeter) and others in selected subgroups only (C-reactive protein, procalcitonin, glucometer). The objective of this trial was to determine whether the clinical outcome of febrile children managed by the e-POCT tool was non-inferior to that of febrile children managed by a validated electronic algorithm derived from IMCI (ALMANACH), while reducing the proportion with antibiotic prescription. We performed a randomized (at patient level, blocks of 4), controlled non-inferiority study among children aged 2-59 months presenting with acute febrile illness to 9 outpatient clinics in Dar es Salaam, Tanzania. In parallel, routine care was documented in 2 health centers. The primary outcome was the proportion of clinical failures (development of severe symptoms, clinical pneumonia on/after day 3, or persistent symptoms at day 7) by day 7 of follow-up. Non-inferiority would be declared if the proportion of clinical failures with e-POCT was no worse than the proportion of clinical failures with ALMANACH, within statistical variability, by a margin of 3%. The secondary outcomes included the proportion with antibiotics prescribed on day 0, primary referrals, and severe adverse events by day 30 (secondary hospitalizations and deaths). We enrolled 3,192 patients

'Safety netting' advice allows general practitioners (GPs) to cope with diagnostic uncertainty in primary care. It informs patients on 'red flag' features and when and how to seek further help. There is, however, insufficient evidence to support useful choices regarding 'safety netting' procedures. To explore how GPs apply 'safety netting' in acutely ill children in Flanders. We designed a qualitative study consisting of semi-structured interviews with 37 GPs across Flanders. Two researchers performed qualitative analysis based on grounded theory components. Although unfamiliar with the term, GPs perform 'safety netting' in every acutely ill child, guided by their intuition without the use of specific guidelines. They communicate 'red flag' features, expected time course of illness and how and when to re-consult and try to tailor their advice to the context, patient and specific illness. Overall, GPs perceive 'safety netting' as an important element of the consultation, acknowledging personal and parental limitations, such as parents' interpretation of their advice. GPs do not feel a need for any form of support in the near future. GPs apply 'safety netting' intuitively and tailor the content. Further research should focus on the impact of 'safety netting' on morbidity and how the advice is conveyed to parents.

To examine the incidence, treatment, and consequences of febrile neutropenia across inpatient and outpatient care settings. Data were obtained from Humedica's National Electronic Health Record-Derived Longitudinal Patient-Level Database (2007-2010). The study population included adult patients who received myelosuppressive chemotherapy for a solid tumor or non-Hodgkin's lymphoma. For each patient, each chemotherapy regimen course and each cycle within each regimen course was characterized. Febrile neutropenia episodes were identified on a cycle-specific basis based on any of the following: (1) absolute neutrophil count <1.0 × 10(9)/L and evidence of infection or fever; (2) inpatient diagnosis of neutropenia, fever, or infection; (3) outpatient diagnosis of neutropenia and non-prophylactic antimicrobial use; or (4) mention of febrile neutropenia in physician notes. Febrile neutropenia episodes were categorized as inpatient or outpatient based on the initial setting of care (i.e. acute-care inpatient facility vs. ambulatory care facility). Febrile neutropenia consequences included hospital length of stay and mortality (inpatient cases only), as well as number of febrile neutropenia-related outpatient encounters. Among the 2131 patients in this study, 401 experienced a total of 458 febrile neutropenia episodes. Risk of febrile neutropenia during the chemotherapy regimen course was 16.8% (95% CI: 15.3, 18.4). In cycle 1 alone, risk of febrile neutropenia was 8.1% (7.1, 9.3). Most febrile neutropenia episodes (83.2%) were initially treated in the inpatient setting; the hospital mortality rate was 8.1% (5.8, 11.1), and mean hospital length of stay was 8.4 days (7.7, 9.1). Among febrile neutropenia episodes initially treated in the outpatient setting (16.8%), the mean number of outpatient management encounters was 2.6 (2.1, 3.1), most of which were in the physician's office (69.2%) or emergency department (26.9%). Febrile neutropenia remains a common occurrence among

We enrolled consecutive febrile admissions to two hospitals in Moshi, Tanzania. Confirmed leptospirosis was defined as a ≥ 4-fold increase in microscopic agglutination test (MAT) titer; probable leptospirosis as reciprocal MAT titer ≥ 800; and exposure to pathogenic leptospires as titer ≥ 100. Among 870 patients enrolled in the study, 453 (52.1%) had paired sera available, and 40 (8.8%) of these met the definition for confirmed leptospirosis. Of 832 patients with ≥ 1 serum sample available, 30 (3.6%) had probable leptospirosis and an additional 277 (33.3%) had evidence of exposure to pathogenic leptospires. Among those with leptospirosis the most common clinical diagnoses were malaria in 31 (44.3%) and pneumonia in 18 (25.7%). Leptospirosis was associated with living in a rural area (odds ratio [OR] 3.4, P < 0.001). Among those with confirmed leptospirosis, the predominant reactive serogroups were Mini and Australis. Leptospirosis is a major yet underdiagnosed cause of febrile illness in northern Tanzania, where it appears to be endemic. PMID:21813847

There are limited data on the negative effects of exercise in athletes with acute infective illness. The aim of this study was to determine whether a recently diagnosed prerace acute illness in runners affects the ability to finish a race. Runners were prospectively evaluated in the 3 days before the race for acute infective illness and then received participation advice using clinical criteria based on systemic or localised symptoms/signs. We compared the did-not-start and the did-not-finish frequencies of ill runners (Ill=172: localised=58.7%; systemic=41.3%) with that of a control group of runners (Con=53 734). Runners with a systemic illness were 10.4% more likely not to start compared with controls (29.6% vs 19.2%) (p=0.0073). The risk difference of not starting the race in runners who were advised not to run the race compared with controls was 37.3% (56.5% vs 19.2%, p<0.0001). Compared with controls, runners with illness had a significantly (p<0.05) greater risk (any illness (5.2% vs 1.6%), systemic illness (8.0% vs 1.6%), illness <24 hours before the race (11.1% vs 1.6%)) and relative risk (prevalence risk ratio) (any illness=3.4, systemic illness=4.9, systemic illness <24 hours before the race=7.0) of not finishing the race. Runners with prerace acute systemic illness, and particularly those diagnosed <24 hours before race day, are less likely to finish the race, indicating a reduction in race performance. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Intensive chemotherapy directed against acute myeloid leukemia of childhood is followed by profound neutropenia and high risk for bacterial and fungal infections, including viridans group streptococci as a common cause for gram-positive septicemia. Few retrospective studies have shown the efficacy of various antibiotic prophylactic regimens in children. We retrospectively studied 50 pediatric patients treated on the AML-BFM 2004 protocol between 2005 and 2015 at St. Anna Children's Hospital and assessed the effect of antibiotic prophylaxis on the frequency of febrile neutropenia and bacterial sepsis. Fifty pediatric patients underwent 199 evaluable chemotherapy cycles. Viridans sepsis occurred after none of 98 cycles with prophylactic administration of teicoplanin/vancomycin in comparison to 12 cases of viridans sepsis among 79 cycles without systemic antibacterial prophylaxis (0 vs. 15 %, p < 0.0001). In addition, there were significantly fewer episodes of febrile neutropenia in the teicoplanin/vancomycin group (44 % vs. no prophylaxis 82 %, p < 0.0001). Severity of infection seemed to be worse when no antibiotic prophylaxis had been administered with a higher rate of intensive care unit treatment (0/98, 0 %, vs. 4/79, 5 %, p = 0.038). So far, no increase of vancomycin-resistant enterococcus isolates in surveillance cultures was noticed. Antibiotic prophylaxis with teicoplanin (or vancomycin) appears safe and feasible and resulted in eradication of viridans sepsis and decreased incidence of febrile neutropenia in pediatric AML patients. The possibility to administer teicoplanin on alternate days on an outpatient basis or at home could contribute to patient's quality of life and decrease health care costs.

Rainstorms increase levels of fecal indicator bacteria in urban coastal waters, but it is unknown whether exposure to seawater after rainstorms increases rates of acute illness. Our objective was to provide the first estimates of rates of acute illness after seawater exposure during both dry- and wet-weather periods and to determine the relationship between levels of indicator bacteria and illness among surfers, a population with a high potential for exposure after rain. We enrolled 654 surfers in San Diego, California, and followed them longitudinally during the 2013-2014 and 2014-2015 winters (33,377 days of observation, 10,081 surf sessions). We measured daily surf activities and illness symptoms (gastrointestinal illness, sinus infections, ear infections, infected wounds). Compared with no exposure, exposure to seawater during dry weather increased incidence rates of all outcomes (e.g., for earache or infection, adjusted incidence rate ratio (IRR) = 1.86, 95% confidence interval (CI): 1.27, 2.71; for infected wounds, IRR = 3.04, 95% CI: 1.54, 5.98); exposure during wet weather further increased rates (e.g., for earache or infection, IRR = 3.28, 95% CI: 1.95, 5.51; for infected wounds, IRR = 4.96, 95% CI: 2.18, 11.29). Fecal indicator bacteria measured in seawater (Enterococcus species, fecal coliforms, total coliforms) were strongly associated with incident illness only during wet weather. Urban coastal seawater exposure increases the incidence rates of many acute illnesses among surfers, with higher incidence rates after rainstorms. © The Author(s) 2017.

De Rosa, Silvia; Samoni, Sara; Villa, Gianluca; Ronco, Claudio

2017-01-01

Patients with chronic kidney disease (CKD) are at high risk for developing critical illness and for admission to intensive care units (ICU). 'Critically ill CKD patients' frequently develop an acute worsening of renal function (i.e. acute-on-chronic, AoC) that contributes to long-term kidney dysfunction, potentially leading to end-stage kidney disease (ESKD). An integrated multidisciplinary effort is thus necessary to adequately manage the multi-organ damage of those kidney patients and contemporaneously reduce the progression of kidney dysfunction when they are critically ill. The aim of this review is to describe (1) the pathophysiological mechanisms underlying the development of AoC kidney dysfunction and its role in the progression toward ESKD; (2) the most common clinical presentations of critical illness among CKD/ESKD patients; and (3) the continuum of care for CKD/ESKD patients from maintenance hemodialysis/peritoneal dialysis to acute renal replacement therapy performed in ICU and, vice-versa, for AoC patients who develop ESKD. © 2017 S.

This study evaluated the controversial relationship between the duration of fever before treatment initiation (FBT) for a febrile urinary tract infection (UTI), with renal scarring based on dimercaptosuccinic acid scintigraphy (DMSA) findings. The inpatient records of 148 children under two years of age with a first episode of febrile UTI were analysed. Acute and repeat DMSA findings, and clinical and laboratory parameters were evaluated. Acute DMSA showed that 76 of the 148 children with a febrile UTI had renal lesions: 20 were mild, and 56 were moderate or severe. Repeat DMSA showed renal scarring in 34 patients. The only factors associated with the development of renal scars in the repeat DMSA were FBT of more than 72 hours, the presence and severity of vesicoureteral reflux and increased procalcitonin levels and absolute neutrophil counts. Multiple regression analysis showed that an FBT above 72 hours was the only significant factor that predicted renal scars. Delay in treatment initiation of 72 hours or more was a risk factor for permanent renal scars after the first episode of febrile UTI. Other associated factors were increased procalcitonin and absolute neutrophil count on admission and the presence and severity of vesicouretal reflux. ©2016 Foundation Acta Paediatrica.

Uncertainty and anxiety surround parents' decisions to seek medical help for an acutely ill child. Consultation rates for children are rising, yet little is known about factors that influence parents' help-seeking behaviours. We used focus groups and interviews to examine how 27 parents of children under five years, from a range of socioeconomic groups in the East Midlands of England, use information to make decisions during acute childhood illness at home. This article reports findings elucidating factors that influence help-seeking behaviours. Parents reported that decision-making during acute childhood illness was influenced by a range of personal, social and health service factors. Principal among these was parents' concern to do the right thing for their child. Their ability to assess the severity of the illness was influenced by knowledge and experience of childhood illness. When parents were unable to access their general practitioner (GP), feared criticism from or had lost trust in their GP, some parents reported using services elsewhere such as Accident and Emergency. These findings contribute to explanatory theory concerning parents' help-seeking behaviours. Professional and political solutions have not reduced demand; therefore, collaborative approaches involving the public and professionals are now needed to improve parents' access to information. © The Author(s) 2014.

Limited information exists on the epidemiology of acute febrile respiratory illnesses in tropical South American countries such as Venezuela. The objective of the present study was to examine the epidemiology of influenza-like illness (ILI) in two hospitals in Maracay, Venezuela. We performed a prospective surveillance study of persons with ILI who presented for care at two hospitals in Maracay, Venezuela, from October 2006 to December 2010. A respiratory specimen and clinical information were obtained from each participant. Viral isolation and identification with immunofluorescent antibodies and molecular methods were employed to detect respiratory viruses such as adenovirus, influenza A and B, parainfluenza, and respiratory sincytial virus, among others. There were 916 participants in the study (median age: 17 years; range: 1 month--86 years). Viruses were identified in 143 (15.6%) subjects, and one participant was found to have a co-infection with more than one virus. Influenza viruses, including pandemic H1N1 2009, were the most frequently detected pathogens, accounting for 67.4% (97/144) of the viruses detected. Adenovirus (15/144), parainfluenza virus (13/144), and respiratory syncytial virus (11/144) were also important causes of ILI in this study. Pandemic H1N1 2009 virus became the most commonly isolated influenza virus during its initial appearance in 2009. Two waves of the pandemic were observed: the first which peaked in August 2009 and the second--higher than the preceding - that peaked in October 2009. In 2010, influenza A/H3N2 re-emerged as the most predominant respiratory virus detected. Influenza viruses were the most commonly detected viral organisms among patients with acute febrile respiratory illnesses presenting at two hospitals in Maracay, Venezuela. Pandemic H1N1 2009 influenza virus did not completely replace other circulating influenza viruses during its initial appearance in 2009. Seasonal influenza A/H3N2 was the most common influenza

Undernutrition in hospitalised patients is likely to be contributed to by the dual action of the underlying disease and acute catabolism associated with it. The aim of this study was to measure the association between underlying disease and nutritional status in acutely ill older patients. Four hundred and forty-five randomly selected patients had their nutritional status assessed from anthropometric, haematological and biochemical data within 72h of admission, at 6 weeks and at 6 months. Data were also collected on age, disability, chronic illness, medications, smoking and acute-phase response. Patients admitted with chronic obstructive pulmonary disease (COPD), heart failure and falls had significantly lower anthropometric measurements compared with all study populations than for example those admitted with ischaemic heart disease (IHD), chest infections and for elective hip surgery. Nutritional status has deteriorated between admission and 6 weeks among those with COPD, heart failure and falls compared with all study populations. Over 6-months 33 (52%) COPD patients and 14 (39%) heart failure patients were readmitted to hospital compared with 137 (35%) patients of all study populations. Nutritional supplements lead to a limited but significant benefit in transferrin and red cell folate among patients with heart failure and IHD. In older patients, underlying diseases have variable contributions to the poor nutritional status associated with acute illness.

To validate serum neutrophil gelatinase-associated lipocalin (NGAL) as an early biomarker for acute kidney injury in critically ill children with septic shock. Observational cohort study. Fifteen North American pediatric intensive care units (PICUs). A total of 143 critically ill children with systemic inflammatory response syndrome (SIRS) or septic shock and 25 healthy controls. None. Serum NGAL was measured during the first 24 hrs of admission to the PICU. Acute kidney injury was defined as a blood urea nitrogen concentration >100 mg/dL, serum creatinine >2 mg/dL in the absence of preexisting renal disease, or the need for dialysis. There was a significant difference in serum NGAL between healthy children (median 80 ng/mL, interquartile ratio [IQR] 55.5-85.5 ng/mL), critically ill children with SIRS (median 107.5 ng/mL, IQR 89-178.5 ng/mL), and critically ill children with septic shock (median 302 ng/mL, IQR 151-570 ng/mL; p < .001). Acute kidney injury developed in 22 of 143 (15.4%) critically ill children. Serum NGAL was significantly increased in critically ill children with acute kidney injury (median 355 ng/mL, IQR 166-1322 ng/mL) compared with those without acute kidney injury (median 186 ng/mL, IQR 98-365 ng/mL; p = .009). Serum NGAL is a highly sensitive but nonspecific predictor of acute kidney injury in critically ill children with septic shock. Further validation of serum NGAL as a biomarker of acute kidney injury in this population is warranted.

 Existing information on acute idiopathic scrotal edema relies on small case series and textbooks.  We searched reports with no date limits on acute idiopathic scrotal edema.  Thirty-seven studies were included. Sixteen case series addressed the prevalence of acute idiopathic scrotal edema among males with acute scrotum: among 3,403 cases, the diagnosis of acute idiopathic scrotal edema was made in 413 cases (12%). Twenty-four reports addressed history, findings, management, and course of acute idiopathic scrotal edema in 311 patients. The patients mostly ranged in age from 5 to 8 years, presented with acute scrotal redness and swelling, associated or not with mild pain. Ninety percent or more of the cases developed in patients without atopic diathesis and were not preceded by inguinoscrotal surgery, acute febrile illnesses, or trauma. They were afebrile; in good general condition; and presented without pruritus, nausea or vomiting, or abdominal pain. The lesions were bilateral in two-thirds and unilateral in one-third of the cases. The condition resolved spontaneously within 2 to 3 days without sequelae. Approximately 10% of the cases experienced a recurrence.  Acute idiopathic scrotal edema is a self-limiting condition that accounts for ≥ 10% of cases of acute scrotum in children and adolescents.

To illustrate the histopathological features of acute acalculous cholecystitis (AAC) of critically ill patients and to compare them with those of acute calculous cholecystitis (ACC) and normal gallbladders. We studied 34 gallbladders with AAC and compared them with 28 cases of ACC and 14 normal gallbladders. Histological features were systematically evaluated. Typical features in AAC were bile infiltration, leucocyte margination of blood vessels and lymphatic dilation. Bile infiltration in the gallbladder wall was more common and extended wider and deeper into the muscle layer in AAC compared with ACC. Epithelial degeneration and defects and widespread occurrence of inflammatory cells were typical features in ACC. Necrosis in the muscle layer was also more common and extended wider and deeper in ACC. There were no differences in the occurrence of capillary thromboses, lymphatic follicles or Rokitansky-Aschoff sinuses between the AAC and ACC samples. There are characteristic differences in histopathology between AAC and ACC, although due to overlap, none appeared to be specific as such for either condition. These results suggest that AAC is largely a manifestation of systemic critical illness, whereas ACC is a local disease of the gallbladder.

Background Limited information exists on the epidemiology of acute febrile respiratory illnesses in tropical South American countries such as Venezuela. The objective of the present study was to examine the epidemiology of influenza-like illness (ILI) in two hospitals in Maracay, Venezuela. Methodology/Principal Findings We performed a prospective surveillance study of persons with ILI who presented for care at two hospitals in Maracay, Venezuela, from October 2006 to December 2010. A respiratory specimen and clinical information were obtained from each participant. Viral isolation and identification with immunofluorescent antibodies and molecular methods were employed to detect respiratory viruses such as adenovirus, influenza A and B, parainfluenza, and respiratory sincytial virus, among others. There were 916 participants in the study (median age: 17 years; range: 1 month – 86 years). Viruses were identified in 143 (15.6%) subjects, and one participant was found to have a co-infection with more than one virus. Influenza viruses, including pandemic H1N1 2009, were the most frequently detected pathogens, accounting for 67.4% (97/144) of the viruses detected. Adenovirus (15/144), parainfluenza virus (13/144), and respiratory syncytial virus (11/144) were also important causes of ILI in this study. Pandemic H1N1 2009 virus became the most commonly isolated influenza virus during its initial appearance in 2009. Two waves of the pandemic were observed: the first which peaked in August 2009 and the second - higher than the preceding - that peaked in October 2009. In 2010, influenza A/H3N2 re-emerged as the most predominant respiratory virus detected. Conclusions/Significance Influenza viruses were the most commonly detected viral organisms among patients with acute febrile respiratory illnesses presenting at two hospitals in Maracay, Venezuela. Pandemic H1N1 2009 influenza virus did not completely replace other circulating influenza viruses during its initial

Scrub typhus is becoming a clinically important cause of acute undifferentiated febrile illness in Taiwan. The incubation period is between 6 and 21 days after exposure. It is transmitted by chiggers (larva of trombiculid mite) in long grasses and in dirt-floor homes, with infection characterized by a flu-like illness of fever, headache, and myalgia lasting approximately 1 week. It has various systemic manifestations, including GI symptoms. In some, the illness progresses to multiorgan dysfunction syndrome and death. We report on a 13-year-old boy who lived in Taipei City and who had initially tentative diagnosis of acute pyrexia of unknown origin with high fever up to 40.3°C for 1 week, but later had thrombocytopenia and diffuse abdominal pain with peritoneal sign suspected acute appendicitis. During the clinical course, septic shock and disseminated intravascular coagulopathy (DIC) were noted. There were skin rash in his trunk and extremities and an eschar with black crust surrounded by a scaling erythematous rim on his right buttock. In addition, we got the information of his travel history in Green Island and Orchid Island for 10 days.With the correct antibiotics, vancomycin, meropenem, and doxycycline, the patient was getting better and corresponding with high level of granulysin and tumor necrosis factor-alpha. The diagnosis of scrub typhus was confirmed by the biopsy of eschar and high quantitative real-time polymerase chain reaction values of Orientia tsutsugamushi (16sRNA and 56 kDa) tested by Centers for Disease Control and Prevention, Taiwan. Histopathological findings of the eschar revealed the leukocytoclastic vasculitis, crust and thrombus formation with many gram-negative microorganisms, O. tsutsugamushi demonstrated by 47 kDa monoclonal antibody immunohistochemical stain and electromicroscopy. After the careful selection of appropriate antibiotics including meropenem, vancomycin, and doxycycline, he recovered and was subsequently discharged 7 days

Infusional β-lactam antibiotics in febrile neutropenia: has the time come?

PubMed

Abbott, Iain J; Roberts, Jason A

2012-12-01

Febrile neutropenia presents a clinical challenge in which timely and appropriate antibiotic exposure is crucial. In the context of altered pharmacokinetics and rising bacterial resistance, standard antibiotic doses are unlikely to be sufficient. This review explores the potential utility of altered dosing approaches of β-lactam antibiotics to optimize treatment in febrile neutropenia. There is a dynamic relationship between the antibiotic, the infecting pathogen, and the host. Great advancements have been made in the understanding of the pharmacokinetic changes in critical illness and the pharmacodynamic relationships of antibiotics in these settings. Antibiotic treatment in febrile neutropenia is becoming increasingly difficult. Patients are of higher acuity, receive more intensive chemotherapy regimens leading to prolonged neutropenia, and are often exposed to multiple antibiotic courses. These patients display significant variability in antibiotic clearances and increases in volume of distribution compared with standard ward-based patients. Rising antibiotic resistance and a lack of new antibiotics in production have prompted alternative dosing strategies based on pharmacokinetic/pharmacodynamic data, such as extended or continuous infusions of β-lactam antibiotics, to maximize the likelihood of treatment success. A definitive study that describes a mortality benefit of such dosing regimens remains elusive and the theoretical advantages require testing in well designed clinical trials.

Forearm and upper-arm oscillometric blood pressure comparison in acutely ill adults.

When patients' upper arms are not accessible and/or when cuffs do not fit large upper arms, the forearm site is often used for blood pressure (BP) measurement. The purpose of this study is to compare forearm and upper-arm BPs in 70 acutely ill adults, admitted to a community hospital's 14-bed ICU. Using Philips oscillometric monitors, three repeated measures of forearm and upper-arm BPs are obtained with head of bed flat and with head of bed elevated at 30 degrees. Arms are resting on the bed. Paired t tests show statistically significant differences in systolic BPs, diastolic BPs, and mean arterial pressures in the supine and head-elevated positions. Bland-Altman analyses indicate that forearm and upper-arm oscillometric BPs are not interchangeable in acutely ill adults.

Many critically ill patients experience moderate to severe acute pain that is frequently undetected and/or undertreated. Acute pain in this patient cohort not only derives from their injury and/or illness, but also as a consequence of delivering care whilst stabilising the patient. Emergency nurses are increasingly responsible for the safety and wellbeing of critically ill patients, which includes assessing, monitoring and managing acute pain. How emergency nurses manage acute pain in critically ill adult patients is unknown. The objective of this study is to explore how emergency nurses manage acute pain in critically ill patients in the Emergency Department. In this paper, we provide a detailed description of the methods and protocol for a multiphase sequential mixed methods study, exploring how emergency nurses assess, monitor and manage acute pain in critically ill adult patients. The objective, method, data collection and analysis of each phase are explained. Justification of each method and data integration is described. Synthesis of findings will generate a comprehensive picture of how emergency nurses' perceive and manage acute pain in critically ill adult patients. The results of this study will form a knowledge base to expand theory and inform research and practice.

To conduct a preliminary study of occupational respiratory complaints in farmers who have experienced organic dust toxic syndrome (ODTS) symptoms. Cross-sectional. An agricultural trade show. None. Two hundred ninety-seven people (204 men, 93 women) completed a questionnaire about agricultural practices, respiratory health (including history of febrile episodes while handling grain), and use of respirators. Spirometry was also performed. ODTS symptoms were described by 107 of the people (36%). A strong significant association was found between ODTS and cough or chest tightness after handling grain (odds ratio [OR], 7.5; 95% confidence ratio [CI], 4.2 to 13.5). People who experienced cough or chest tightness after handling grain were more likely to report handling grain sorghum than people who had not experienced cough or chest tightening after handling grain (OR, 2.1; 95% CI, 1.3 to 3.5). The strong association seen between ODTS and frequent use of a respirator while working in grain bins (OR, 3.9; 95% CI, 1.6 to 9.4) may indicate that farmers began using respirators after respiratory symptoms developed. Having a history consistent with ODTS exposure was very common in the farmers surveyed. Farmers who had a history consistent with ODTS were more likely to report cough or chest tightness with handling grain. Exposure to grain sorghum was more likely to be associated with respiratory symptoms than was exposure to other types of grain. There is a need for additional studies to further examine the relationship between ODTS and respiratory symptoms with grain dust exposure in farmers.

To evaluate the determinants of compliance with national policies recommending Artemisinin Combination Therapy (ACT) for the treatment of uncomplicated malaria in the community. We used data from Gambia, Ghana, Kenya, Nigeria, and Uganda national household surveys that were conducted with a standardized World Health Organization (WHO) methodology to measure access to and use of medicines. We analyzed all episodes of acute fever reported in the five surveys. We used logistic regression models accounting for the clustered design of the surveys to identify determinants of seeking care in public healthcare facilities, of being treated with antimalarials, and of receiving ACT. Overall, 92% of individuals with a febrile episode sought care outside the home, 96% received medicines, 67% were treated with antimalarials, and 16% received ACT. The choice of provider was influenced by perceptions about medicines availability and affordability. In addition, seeking care in a public healthcare facility was the single most important predictor of treatment with ACT [odds ratio (OR): 4.64, 95% confidence intervals (CI): 2.98-7.22, P < 0.001]. Children under 5 years old were more likely than adults to be treated with antimalarials [OR: 1.28, CI: 0.91-1.79, not significant (NS)] but less likely to receive ACT (OR: 0.80, CI: 0.57-1.13, NS). Our results confirm the high prevalence of presumptive antimalarial treatment for acute fever, especially in public healthcare facilities where poor people seek care. They show that perceptions about access to medicines shape behaviors by directing patients and caregivers to sources of care where they believe medicines are accessible. The success of national policies recommending ACT for the treatment of uncomplicated malaria depends not only on restricting ACT to confirmed malaria cases, but also on ensuring that ACT is available and affordable for those who need it.

Kawasaki syndrome, an acute systemic inflammatory illness of unknown origin usually affecting children, may develop into a serious illness complicated by coronary artery aneurysms or myocarditis. This report describes an adult with Kawasaki syndrome studied by right ventricular endomyocardial biopsy and cardiac catheterization during the acute and recovery phases of illness. The initial biopsy specimen showed acute myocarditis and was associated with hemodynamic evidence of biventricular dysfunction, a severely depressed left ventricular ejection fraction and global hypokinesia. With time, there was spontaneous and rapid resolution of the inflammatory cell infiltrate with concurrent return to normal myocardial function. Right ventricular endomyocardial biopsy studies early in the course of the cardiac disease associated with Kawasaki syndrome may correlate with ventricular function and may be useful for monitoring immunosuppressive therapy in patients with this syndrome.

Acute and convalescent serum samples were collected from febrile inpatients identified at two hospitals in Moshi, Tanzania. Confirmed brucellosis was defined as a positive blood culture or a ≥ 4-fold increase in microagglutination test titer, and probable brucellosis was defined as a single reciprocal titer ≥ 160. Among 870 participants enrolled in the study, 455 (52.3%) had paired sera available. Of these, 16 (3.5%) met criteria for confirmed brucellosis. Of 830 participants with ≥ 1 serum sample, 4 (0.5%) met criteria for probable brucellosis. Brucellosis was associated with increased median age (P = 0.024), leukopenia (odds ratio [OR] 7.8, P = 0.005), thrombocytopenia (OR 3.9, P = 0.018), and evidence of other zoonoses (OR 3.2, P = 0.026). Brucellosis was never diagnosed clinically, and although all participants with brucellosis received antibacterials or antimalarials in the hospital, no participant received standard brucellosis treatment. Brucellosis is an underdiagnosed and untreated cause of febrile disease among hospitalized adult and pediatric patients in northern Tanzania. PMID:23091197

Local understandings of malaria and use of preventive measures-are critical factors in sustained control of malaria. This study assessed caretakers' knowledge on malaria, use of Long Lasting Insecticide Treated Nets (LLINs) and care-seeking behavior for their children's illness in different malaria transmission settings of Ethiopia. Data were collected from 709 caretakers of children of 2-9 years of age during in 2016. A standard questionnaire was used to assess caretakers' perceptions of malaria, use of LLIN and care seeking behavior for febrile illness of children aged 2-9 years. The caretakers recognized malaria mostly by chills (70.4%, 499/709), fever (45.7%, 324/709) and headache (39.8%, 282/709). Overall, only 66.4% (471) of the caretakers knew that mosquito bite caused malaria and that it was quite heterogeneous by localities (ranging from 26.1% to 89.4%) and altitude (p < 0.05). Majority, 72.2% (512), of the caretakers knew that sleeping under LLIN could prevent malaria. Overall knowledge on malaria (mean = 51.2%) was very low with significant variations by localities, altitude and levels of malaria transmission, being low in high altitude and low in transmission areas (p < 0.05). Four hundred ninety-one (69.3%, 491/709) of the children slept under LLIN in the previous night. Of malaria related knowledge items, only knowledge of LLIN was associated with net use; non-use of LLN was higher among caretakers who did not know the role of LLIN (AOR = 0.47, 95%CI: 0.28-0.77, p = 0.003). Of course, attributing causation of malaria to stagnant water discouraged use of net (p = 0.021). Of febrile children (n = 122), only 50 (41.0%) sought care with only 17 (34.0%) seeking the care promptly. There was no significant link between knowledge of malaria and care seeking behavior (p > 0.05). However, knowledge of malaria had some level of influence on treatment source preference where caretakers with greater knowledge preferred pharmacy as

To evaluate the accuracy of an acute (99m)Tc-dimercaptosuccinic acid (DMSA) scan in predicting dilating vesicoureteral reflux (VUR) among young children with a febrile urinary tract infection (UTI). The medical records of children (≤ 2 years of age), presenting with febrile UTI between January 2000 and December 2011, were retrospectively reviewed. A total of 523 children were included in this study, of whom 397 children (75.9%) had abnormal DMSA results and 178 children (34.0%) were identified as VUR on micturating cystourethrography (MCU). Among all the patients, the number of children with dilating VUR was 151 (28.9%). The rate of abnormal results on DMSA for the dilating VUR group was significantly higher than the rates for the non-VUR and low-grade VUR groups (P < .01). In the <6 months age group and ≥ 6 months age group, the sensitivities of DMSA in predicting dilating VUR were 96.15% and 100.0%, respectively, the negative predictive values were 97.26% and 100.0%, respectively, and the negative likelihood ratios were 0.0911 and 0.0000, respectively. For children ≤ 2 years of age with a febrile UTI, an acute DMSA scan is valuable in the exclusion of dilating VUR. The likelihood of the presence of dilating VUR on MCU is rather low when the result of DMSA is negative. DMSA should be conducted to assess the need for an MCU.

Chronically critically ill patients have recurrent infections, organ dysfunction, and at least half die within 1 year. They are frequently cared for in long-term acute care hospitals, yet little is known about their experience in this setting. Our objective was to explore the understanding and expectations and goals of these patients and surrogates. We conducted semi-structured interviews with chronically critically ill long-term acute care hospital patients or surrogates. Conversations were recorded, transcribed, and analyzed. One long-term acute care hospital. Chronically critically ill patients, defined by tracheotomy for prolonged mechanical ventilation, or surrogates. Semi-structured conversation about quality of life, expectations, and planning for setbacks. A total of 50 subjects (30 patients and 20 surrogates) were enrolled. Thematic analyses demonstrated: 1) poor quality of life for patients; 2) surrogate stress and anxiety; 3) optimistic health expectations; 4) poor planning for medical setbacks; and 5) disruptive care transitions. Nearly 80% of patient and their surrogate decision makers identified going home as a goal; 38% were at home at 1 year. Our study describes the experience of chronically critically ill patients and surrogates in an long-term acute care hospital and the feasibility of patient-focused research in this setting. Our findings indicate overly optimistic expectations about return home and unmet palliative care needs, suggesting the need for integration of palliative care within the long-term acute care hospital. Further research is also needed to more fully understand the challenges of this growing population of ICU survivors.

Performance Requirements to Achieve Cost-Effectiveness of Point-of-Care Tests for Sepsis Among Patients with Febrile Illness in Low-Resource Settings.

Bacterial sepsis is an important cause of mortality in low- and middle-income countries, yet distinguishing patients with sepsis from those with other illnesses remains a challenge. Currently, management decisions are based on clinical assessment using algorithms such as Integrated Management of Adolescent and Adult Illness. Efforts to develop and evaluate point-of-care tests (POCTs) for sepsis to guide decisions on the use of antimicrobials are underway. To establish the minimum performance characteristics of such a test, we varied the characteristics of a hypothetical POCT for sepsis required for it to be cost-effective and applied a decision tree model to a population of febrile patients presenting at the district hospital level in a low-resource setting. We used a case fatality probability of 20% for appropriately treated sepsis and of 50% for inappropriately treated sepsis. On the basis of clinical assessment for sepsis with established sensitivity of 0.83 and specificity of 0.62, we found that a POCT for sepsis with a sensitivity of 0.83 and a specificity of 0.94 was cost-effective, resulting in parity in survival but costing $1.14 less per live saved. A POCT with accuracy equivalent to the best malaria rapid diagnostic test was cheaper and more effective than clinical assessment. © The American Society of Tropical Medicine and Hygiene.

To determine the seroprevalence of leptospirosis among febrile inpatient cases in northeastern Malaysia. A hospital-based cross-sectional study was conducted among 999 febrile cases admitted to 10 hospitals in northeastern Malaysia. A survey using a proforma sheet was used to obtain sociodemographic and occupational information. Serum samples were screened for leptospirosis by IgM enzyme-linked immunosorbent assay test (IgM ELISA) and confirmed by microscopic agglutination test (MAT). There was an equivalent distribution of males and females in the 999 respondents enrolled in the study. The majority were Malay (94.7%) and their mean age was 39.4 (standard deviation 17.6) years. The overall seroprevalence of leptospirosis was 8.4% (95% confidence interval (CI) 6.8-10.3) (n=84). The high-risk occupational group was found to have a higher seroprevalence, which was 56% (95% CI 45.3-66.1) (n=47). The predominant serogroup was Sejroe (82.1%, 95% CI 72.6-88.8) (n=69). This study revealed a possible high seroprevalence of leptospirosis among febrile cases, indicating the need to review the importance of adding leptospirosis to the case investigation of febrile illness, especially among high-risk occupational groups in Malaysia, as well as in other endemic countries.

Acute illness-induced behavioral alterations are similar to those observed during withdrawal from acute alcohol exposure

Exposure to an immunogen results in a constellation of behavioral changes collectively referred to as “sickness behaviors,” with alterations in cytokine expression previously shown to contribute to this sickness response. Since behaviors observed during ethanol withdrawal are strikingly similar to sickness behaviors, we hypothesized that behavioral manifestations of ethanol withdrawal might be an expression of sickness behaviors induced by ethanol-related changes in peripheral and/or central cytokine expression. Accordingly, behaviors exhibited during a modified social investigation test were first characterized in male rats following an acute injection of lipopolysaccharide (LPS; 100 μg/kg). Subsequently, behavioral changes after either a high (4-g/kg; Experiment 2) or low dose (0.5 g/kg; Experiment 3) of ethanol were also examined in the same social investigation test, as well as in the forced-swim test (FST; Experiment 4). Results from these experiments demonstrated similar reductions in both exploration and social investigatory behavior during acute illness and ethanol withdrawal, while a seemingly paradoxical decrease in immobility was observed in the FST during acute ethanol withdrawal. In follow-up studies, neither indomethacin (Experiment 5) nor interleukin-1 receptor antagonist (Experiment 6) pre-exposure reversed the ethanol withdrawal-induced behavioral changes observed in this social investigation test. Taken together, these studies demonstrate that the behavioral sequelae of acute illness and ethanol withdrawal are similar in nature, while antagonist studies suggest that these behavioral alterations are not reversed by blockade of IL-1 receptors or inhibition of prostaglandin synthesis. Though a direct mechanistic link between cytokines and the expression of acute ethanol withdrawal-related behaviors has yet to be found, future studies examining the involvement of brain cytokines as potential mediators of ethanol effects are greatly needed.

Chronically ill patients such as people with type 2 diabetes develop perceptions of their illness, which will influence their coping behaviour. Perceptions are formed once a health threat has been recognised. Many people with type 2 diabetes suffer from multimorbidity, for example the combination with cardiovascular disease. Perceptions of one illness may influence perceptions of the other condition. The aim of the current study was to evaluate the effect of an intervention in type 2 diabetes patients with a first acute coronary event on change in illness perceptions and whether this mediates the intervention effect on health status. The current study is a secondary data analysis of a RCT. Two hundred one participants were randomised (1:1 ratio) to the intervention (n = 101, three home visits) or control group (n = 100). Outcome variables were diabetes and acute coronary event perceptions, assessed with the two separate Brief Illness Perceptions Questionnaires (BIPQs); and health status (Euroqol Visual Analog Scale (EQ-VAS)). The intervention effect was analysed using ANCOVA. Linear regression analyses were used to assess whether illness perceptions mediated the intervention effect on health status. A positive intervention effect was found on the BIPQ diabetes items coherence and treatment control (F = 8.19, p = 0.005; F = 14.01, p < 0.001). No intervention effect was found on the other BIPQ diabetes items consequence, personal control, identity, illness concern and emotional representation. Regarding the acute coronary event, a positive intervention effect on treatment control was found (F = 7.81, p = 0.006). No intervention effect was found on the other items of the acute coronary event BIPQ. Better diabetes coherence was associated with improved health status, whereas perceiving more treatment control was not. The mediating effect of the diabetes perception 'coherence' on health status was not significant. Targeting illness

Although thromboprophylaxis reduces the incidence of venous thromboembolism in acutely ill medical patients, an associated reduction in the rate of death from any cause has not been shown. We conducted a double-blind, placebo-controlled, randomized trial to assess the effect of subcutaneous enoxaparin (40 mg daily) as compared with placebo--both administered for 10±4 days in patients who were wearing elastic stockings with graduated compression--on the rate of death from any cause among hospitalized, acutely ill medical patients at participating sites in China, India, Korea, Malaysia, Mexico, the Philippines, and Tunisia. Inclusion criteria were an age of at least 40 years and hospitalization for acute decompensated heart failure, severe systemic infection with at least one risk factor for venous thromboembolism, or active cancer. The primary efficacy outcome was the rate of death from any cause at 30 days after randomization. The primary safety outcome was the rate of major bleeding during and up to 48 hours after the treatment period. A total of 8307 patients were randomly assigned to receive enoxaparin plus elastic stockings with graduated compression (4171 patients) or placebo plus elastic stockings with graduated compression (4136 patients) and were included in the intention-to-treat population. The rate of death from any cause at day 30 was 4.9% in the enoxaparin group as compared with 4.8% in the placebo group (risk ratio, 1.0; 95% confidence interval [CI], 0.8 to 1.2; P=0.83). The rate of major bleeding was 0.4% in the enoxaparin group and 0.3% in the placebo group (risk ratio, 1.4; 95% CI, 0.7 to 3.1; P=0.35). The use of enoxaparin plus elastic stockings with graduated compression, as compared with elastic stockings with graduated compression alone, was not associated with a reduction in the rate of death from any cause among hospitalized, acutely ill medical patients.

Background Urinary tract infection (UTI) is an infection that affects part of the urinary tract. Ultrasound is a noninvasive test that can demonstrate the size and shape of kidneys, presence of dilatation of the ureters, and the existence of anatomic abnormalities. The aim of the study is to estimate the value of ultrasound in detecting urinary tract anomalies after first attack of UTI. Methods This study was conducted at the Nephrology Clinic, New Children's Hospital, Faculty of Medicine, Cairo University, from August 2012 to March 2013, and included 30 children who presented with first attack of acute febrile UTI. All patients were subjected to urine analysis, urine culture and sensitivity, serum creatinine, complete blood count, and imaging in the form of renal ultrasound, voiding cysto-urethrography, and renal scan. Results All the patients had fever with a mean of 38.96°C ± 0.44°C and the mean duration of illness was 6.23 ± 5.64 days. Nineteen patients (63.3%) had an ultrasound abnormality. The commonest abnormalities were kidney stones (15.8%). Only 2 patients who had abnormal ultrasound had also vesicoureteric reflux on cystourethrography. Sensitivity of ultrasound was 66.7%, specificity was 37.5%, positive predictive value was 21.1%, negative predictive value was 81.8%, and total accuracy was 43.33%. Conclusion We concluded that ultrasound alone was not of much value in diagnosing and putting a plan of first attack of febrile UTI. It is recommended that combined investigations are the best way to confirm diagnosis of urinary tract anomalies. © The Author(s) 2015.

Body temperature is a time-honored marker of serious bacterial infection, but there are few studies of its test performance. The aim of our study was to determine the accuracy of temperature measured on presentation to medical care for detecting serious bacterial infection. Febrile children 0-5 years of age presenting to the emergency department of a tertiary care pediatric hospital were sampled consecutively. The accuracy of the axillary temperature measured at presentation was evaluated using logistic regression models to generate receiver operating characteristic curves. Reference standard tests for serious bacterial infection were standard microbiologic/radiologic tests and clinical follow-up. Age, clinicians' impression of appearance of the child (well versus unwell) and duration of illness were assessed as possible effect modifiers. Of 15,781 illness episodes 1120 (7.1%) had serious bacterial infection. The area under the receiver operating characteristic curve for temperature was 0.60 [95% confidence intervals (CI): 0.58-0.62]. A threshold of ≥ 38°C had a sensitivity of 0.67 (95% CI: 0.64-0.70), specificity of 0.45 (95% CI: 0.44-0.46), positive likelihood ratio of 1.2 (95% CI: 1.2-1.3) and negative likelihood ratio of 0.7 (95% CI: 0.7-0.8). Age and illness duration had a small but significant effect on the accuracy of temperature increasing its "rule-in" potential. Measured temperature at presentation to hospital is not an accurate marker of serious bacterial infection in febrile children. Younger age and longer duration of illness increase the rule-in potential of temperature but without substantial overall change in its test accuracy.

Differentiating scrub typhus from other acute febrile illness is difficult due to non specificity of clinical symptoms and relative absence of eschar in Indian population. The diagnosis thus relies mainly on laboratory tests. Antibody based serological tests are mainstay of scrub typhus diagnosis. Here, we evaluated the diagnostic performance of IgM ELISA, IgM IFA and ICT to detect antibodies against O. tsutsugamushi in acute serum of febrile patients. The serum samples from 600 randomly selected patients suffering from acute undifferentiated fever were tested by all the three tests mentioned above. We used latent class analysis to generate unbiased results as all the tests for scrub typhus diagnosis are imperfect and none of them can be considered as reference standard. We found that IgM ELISA with cutoff titer 0.5 OD has high diagnostic accuracy (sensitivity 99.9% and specificity 99.15) than IgM IFA (sensitivity 96.8% and specificity 99.7%) for scrub typhus diagnosis. ICT used in our study had very high specificity 100% but low sensitivity (38%) which would limit its use for acute serum samples. ICT being a screening or point of care test, has to be more sensitive while some compromise with specificity is affordable. Hence, optimal cutoff for ICT should be evaluated under different settings. IgM ELISA being simple and affordable could be an alternative diagnostic test to IgM IFA which is subjective and costly.

Fever is a common cause of hospital admission in Bangladesh but causative agents, other than malaria, are not routinely investigated. Enteric fever is thought to be common. Adults and children admitted to Chittagong Medical College Hospital with a temperature of ≥38.0 °C were investigated using a blood smear for malaria, a blood culture, real-time PCR to detect Salmonella Typhi, S. Paratyphi A and other pathogens in blood and CSF and an NS1 antigen dengue ELISA. We enrolled 300 febrile patients with a negative malaria smear between January and June 2012: 156 children (aged ≤15 years) and 144 adults with a median (interquartile range) age of 13 (5-31) years and median (IQR) illness duration before admission of five (2-8) days. Clinical enteric fever was diagnosed in 52 patients (17.3 %), lower respiratory tract infection in 48 (16.0 %), non-specific febrile illness in 48 (16.0 %), a CNS infection in 37 patients (12.3 %), urinary sepsis in 23 patients (7.7 %), an upper respiratory tract infection in 21 patients (7.0 %), and diarrhea or dysentery in 21 patients (7.0 %). Malaria was still suspected in seven patients despite a negative microscopy test. S. Typhi was detected in blood by culture or PCR in 34 (11.3 %) of patients. Of note Rickettsia typhi and Orientia tsutsugamushi were detected by PCR in two and one patient respectively. Twenty-nine (9 %) patients died during their hospital admission (15/160 (9.4 %) of children and 14/144 (9.7 %) adults). Two of 52 (3.8 %) patients with enteric fever, 5/48 (10.4 %) patients with lower respiratory tract infections, and 12/37 (32.4 %) patients with CNS infection died. Enteric fever was confirmed in 11.3 % of patients admitted to this hospital in Bangladesh with non-malaria fever. Lower respiratory tract and CNS infections were also common. CNS infections in this location merit more detailed study due to the high mortality.

To compare the clinical outcomes (duration of signs and symptoms) and the microbiology in Mexican children with non-complicated febrile upper respiratory tract infections (URI), with and without the use of antibiotics. We conducted a prospective cohort study from September 2006 to July 2007. The study population consisted of 880 children aged 6 months to 5 years 11 months, attending four community daycare centers run by the Instituto Mexicano del Seguro Social (IMSS) and three non-IMSS daycare centers. Children with a febrile URI were enrolled before receiving any antimicrobials and were followed up for two weeks. Duration of the fever, cough, runny nose, stuffy nose, irritability, loss of appetite, tiredness, and diarrhea, and isolation of Haemophilus influenzae,Streptococcus pneumoniae, and Streptococcus pyogenes were compared in those children who received antibiotic treatment and those who did not receive antibiotics. During the study period, a total of 145 out of 880 children were enrolled, and among those enrolled, 85/145 (59%) children received antibiotics. There was no significant difference in the duration of the signs and symptoms evaluated in the two groups. Although the proportions of S. pneumoniae, H. influenzae, and S. pyogenes isolated in children with and without antibiotics were comparable, those in whom we isolated S. pneumoniae had both a significantly longer episode of URI, as well as longer lasting diarrhea. Similarly, children receiving trimethoprim-sulfamethoxazole treatment experienced significantly longer durations of fever and diarrhea. The mean duration of signs and symptoms and the microbiological isolates of children with febrile URI were comparable among children treated with or without antibiotics, with the exception of a longer duration of URI and diarrhea in those children with an S. pneumoniae isolate. Our findings suggest that in our population, most cases of febrile URI are caused by viral infections, and demonstrate that

Herpes simplex virus (HSV) encephalitis is associated with a high risk of mortality and sequelae, and early diagnosis and treatment in the emergency department are necessary. However, most patients present with non-specific febrile, acute neurologic impairment; this may lead clinicians to overlook the diagnosis of HSV encephalitis. We aimed to identify which data collected in the first hours in a medical setting were associated with the diagnosis of HSV encephalitis. We conducted a multicenter retrospective case-control study in four French public hospitals from 2007 to 2013. The cases were the adult patients who received a confirmed diagnosis of HSV encephalitis. The controls were all the patients who attended the emergency department of Grenoble hospital with a febrile acute neurologic impairment, without HSV detection by polymerase chain reaction (PCR) in the cerebrospinal fluid (CSF), in 2012 and 2013. A multivariable logistic model was elaborated to estimate factors significantly associated with HSV encephalitis. Finally, an HSV probability score was derived from the logistic model. We identified 36 cases and 103 controls. Factors independently associated with HSV encephalitis were the absence of past neurological history (odds ratio [OR] 6.25 [95 % confidence interval (CI): 2.22-16.7]), the occurrence of seizure (OR 8.09 [95 % CI: 2.73-23.94]), a systolic blood pressure ≥140 mmHg (OR 5.11 [95 % CI: 1.77-14.77]), and a C-reactive protein <10 mg/L (OR 9.27 [95 % CI: 2.98-28.88]). An HSV probability score was calculated summing the value attributed to each independent factor. HSV encephalitis diagnosis may benefit from the use of this score based upon some easily accessible data. However, diagnostic evocation and probabilistic treatment must remain the rule.

Local transmission of Chikungunya virus (CHIKV) was first documented in Trinidad and Tobago (T&T) in July 2014 preceding a large epidemic. At initial presentation, it is difficult to distinguish chikungunya fever (CHIKF) from other acute undifferentiated febrile illnesses (AUFIs), including life-threatening dengue disease. We characterised and compared dengue virus (DENV) and CHIKV infections in 158 patients presenting with suspected dengue fever (DF) and CHIKF at a major hospital in T&T, and performed phylogenetic analyses on CHIKV genomic sequences recovered from 8 individuals. The characteristics of patients with and without PCR-confirmed CHIKV were compared using Pearson’s χ2 and student’s t-tests, and adjusted odds ratios (aORs) and 95% confidence intervals (CIs) were determined using logistic regression. We then compared signs and symptoms of people with RT-qPCR-confirmed CHIKV and DENV infections using the Mann-Whitney U, Pearson’s χ2 and Fisher’s exact tests. Among the 158 persons there were 8 (6%) RT-qPCR-confirmed DENV and 30 (22%) RT-qPCR-confirmed CHIKV infections. Phylogenetic analyses showed that the CHIKV strains belonged to the Asian genotype and were most closely related to a British Virgin Islands strain isolated at the beginning of the 2013/14 outbreak in the Americas. Compared to persons who were RT-qPCR-negative for CHIKV, RT-qPCR-positive individuals were significantly more likely to have joint pain (aOR: 4.52 [95% CI: 1.28–16.00]), less likely to be interviewed at a later stage of illness (days post onset of fever—aOR: 0.56 [0.40–0.78]) and had a lower white blood cell count (aOR: 0.83 [0.71–0.96]). Among the 38 patients with RT-qPCR-confirmed CHIKV or DENV, there were no significant differences in symptomatic presentation. However when individuals with serological evidence of recent DENV or CHIKV infection were included in the analyses, there were key differences in clinical presentation between CHIKF and other AUFIs

Severe acute hypophosphatemia during renal replacement therapy adversely affects outcome of critically ill patients with acute kidney injury.

Hypophosphatemia during renal replacement therapy (RRT) is common in critically ill patients with acute kidney injury (AKI). The clinical consequences of RRT-induced phosphate depletion are not well defined in this patient population, and there is no evidence that intravenous sodium phosphate supplementation (PS) prevents the clinical sequelae of acute hypophosphatemia. The purpose of this retrospective analysis of the Acute Renal Support Registry of the University of Munich was to examine the association between severe hypophosphatemia and severity of and recovery from AKI. 289 ICU patients with AKI on intermittent hemodialysis (IHD) were included in the study. One hundred and forty-nine patients received PS during IHD. Outcomes were short-term (at discharge) and long-term (at 1 year) recovery of renal function and mortality. The two patient groups did not differ in demographics, clinical features, renal characteristics, and frequency of hypophosphatemia at initiation of IHD. Without PS, the frequency of hypophosphatemia increased from 20 to 35%. Severe hypophosphatemia was found in 50% of these patients. By comparison, PS was not associated with an increased frequency of hypophosphatemia. Compared with patients with acute phosphate depletion, patients receiving PS developed less oliguria during IHD, had shorter duration of AKI, higher incidence of complete renal recovery at discharge, and a lower risk of de novo chronic kidney disease. Hypophosphatemia was associated with higher all-cause in-hospital mortality and higher risk of long-term mortality. This multicenter study indicates for the first time that hypophosphatemia during IHD adversely affects short- and long-term outcome of critically-ill patients with AKI. The clinical consequences of the acute hypophosphatemic syndrome may be prevented by PS.

To evaluate the association between acute respiratory distress syndrome and acute kidney injury with respect to their contributions to mortality in critically ill patients. Retrospective analysis of consecutive adult burn patients requiring mechanical ventilation. A 16-bed burn ICU at tertiary military teaching hospital. Adult patients more than 18 years old requiring mechanical ventilation during their initial admission to our burn ICU from January 1, 2003, to December 31, 2011. None. A total 830 patients were included, of whom 48.2% had acute kidney injury (n = 400). These patients had a 73% increased risk of developing acute respiratory distress syndrome after controlling for age, gender, total body surface area burned, and inhalation injury (hazard ratio, 1.73; 95% CI, 1.18-2.54; p = 0.005). In a reciprocal multivariate analysis, acute respiratory distress syndrome (n = 299; 36%) demonstrated a strong trend toward developing acute kidney injury (hazard ratio, 1.39; 95% CI, 0.99-1.95; p = 0.05). There was a 24% overall in-hospital mortality (n = 198). After adjusting for the aforementioned confounders, both acute kidney injury (hazard ratio, 3.73; 95% CI, 2.39-5.82; p < 0.001) and acute respiratory distress syndrome (hazard ratio, 2.16; 95% CI, 1.58-2.94; p < 0.001) significantly contributed to mortality. Age, total body surface area burned, and inhalation injury were also significantly associated with increased mortality. Acute kidney injury increases the risk of acute respiratory distress syndrome in mechanically ventilated burn patients, whereas acute respiratory distress syndrome similarly demonstrates a strong trend toward the development of acute kidney injury. Acute kidney injury and acute respiratory distress syndrome are both independent risks for subsequent death. Future research should look at this interplay for possible early interventions.

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. PMID:25448236

Background. Parainfluenza virus (PIV) is a common cause of acute respiratory tract infections, but little is known about PIV infection in children and adults in Africa, especially in settings where human immunodeficiency virus (HIV) prevalence is high. Methods. We conducted active, prospective sentinel surveillance for children and adults hospitalized with severe acute respiratory illness (SARI) from 2009 to 2014 in South Africa. We enrolled controls (outpatients without febrile or respiratory illness) to calculate the attributable fraction for PIV infection. Respiratory specimens were tested by multiplex real-time reverse-transcription polymerase chain reaction assay for parainfluenza types 1, 2, and 3. Results. Of 18 282 SARI cases enrolled, 1188 (6.5%) tested positive for any PIV type: 230 (19.4%) were type 1; 168 (14.1%) were type 2; 762 (64.1%) were type 3; and 28 (2.4%) had coinfection with 2 PIV types. After adjusting for age, HIV serostatus, and respiratory viral coinfection, the attributable fraction for PIV was 65.6% (95% CI [confidence interval], 47.1–77.7); PIV contributed to SARI among HIV-infected and -uninfected children <5 years of age and among individuals infected with PIV types 1 and 3. The observed overall incidence of PIV-associated SARI was 38 (95% CI, 36–39) cases per 100 000 population and was highest in children <1 year of age (925 [95% CI, 864–989] cases per 100 000 population). Compared with persons without HIV, persons with HIV had an increased relative risk of PIV hospitalization (9.4; 95% CI, 8.5–10.3). Conclusions. Parainfluenza virus causes substantial severe respiratory disease in South Africa among children <5 years of age, especially those that are infected with HIV. PMID:26566534

To evaluate practice nurse (PN) and health visitor (HV) management of patients with acute minor illnesses, monitor the effect on general practitioner (GP) workload, and describe the range of conditions seen by nurses. Patients requesting 'urgent' appointments (within 24 hours) were offered consultations with a PN or HV trained in the management of acute minor illness. Comparative data were collected before and after the establishment of the acute minor illness service. A general practice in Nottingham, England. Patient satisfaction, consultation rate, prescriptions, investigations, referrals and urgent re-consultations for the same condition within 2 weeks. About 2056 urgent consultations were recorded in the study period, of which 332 (16.1%) were seen by PNs and 46 (2.2%) by a HV. High levels of patient satisfaction were reported for all health professionals. Patients seeing the HV reported higher levels of satisfaction than those consulting GPs (P=0.033) and PNs (P=0.010). There was no difference by health professional for prescription rates (P=0.76), re-consultations (P=0.14), or referrals to secondary care (P=0.07). General practitioners were more likely to initiate further investigations than the PNs or HV (P < 0.001). With suitable training, PNs and HVs can successfully manage patients with a range of conditions. General practitioner workload can be reduced while maintaining high patient satisfaction levels.

Acute febrile illness is common among those seeking medical care and is frequently treated empirically with the underlying illness remaining undiagnosed in resource-poor countries. A febrile illness study was conducted 2009-2010 to identify known and unknown pathogens circulating in Nepal. Study methods included diagnostic testing and preliminary ELISA screening of acute and convalescent samples for diseases both known and unknown to be circulating in Nepal, including West Nile virus (WNV). The molecular assays including Polymerase Chain Reaction (PCR), Sanger sequencing and ultra deep sequencing on MiSeq Illumina Platform were conducted to further confirm the presence of WNV. The study enrolled 2,046 patients presenting undifferentiated febrile illness with unknown etiology. Sera from 14 out of 2,046 patients were tested positive for west nile virus (WNV) by nested Reverse Transcription-Polymerase Chain Reaction (RT-PCR). Only two out of 14 cases were confirmed for the presence of WNV by sequencing and identified as WNV lineage 1 phylogentically. The two patients were adult males with fever and no neurological symptoms from Kathmandu and Bharatpur, Nepal. Two out of 2,046 serum samples contained fragments of WNV genome resembling WNV lineage 1, which is evidence of the continued spread of WNV which should be considered a possible illness cause in Nepal.

Evaluating the febrile patient with a rash.

PubMed

McKinnon, H D; Howard, T

2000-08-15

The differential diagnosis for febrile patients with a rash is extensive. Diseases that present with fever and rash are usually classified according to the morphology of the primary lesion. Rashes can be categorized as maculopapular (centrally and peripherally distributed), petechial, diffusely erythematous with desquamation, vesiculobullous-pustular and nodular. Potential causes include viruses, bacteria, spirochetes, rickettsiae, medications and rheumatologic diseases. A thorough history and a careful physical examination are essential to making a correct diagnosis. Although laboratory studies can be useful in confirming the diagnosis, test results often are not available immediately. Because the severity of these illnesses can vary from minor (roseola) to life-threatening (meningococcemia), the family physician must make prompt management decisions regarding empiric therapy. Hospitalization, isolation and antimicrobial therapy often must be considered when a patient presents with fever and a rash.

Pyroglutamic acid (PGA) is challenging to quantify in plasma and is a rare cause of metabolic acidosis that is associated with inherited disorders or acquired after exposure to drugs. We developed a hydrophilic interaction liquid chromatography tandem mass spectrometry method with a short analysis time. We established a reference interval and then measured PGA in acutely ill patients to investigate associations with clinical, pharmaceutical and laboratory parameters. The assay limit of the blank was 0.14μmol/L and was linear to 5000μmol/L with good precision. In-source formation of PGA from glutamate and glutamine was avoided by chromatographic separation. The PGA in controls had a reference interval of 22.6 to 47.8μmol/L. The median PGA concentration in acutely ill patients was similar (P=0.21), but 18 individuals were above the reference interval with concentrations up to 250μmol/L. We detected an association between PGA concentration and antibiotic and acetaminophen administration as well as renal impairment and severity of illness. Elevations of PGA in this unselected cohort were small compared to those reported in patients with pyroglutamic acidosis. The method is suitable for routine clinical use. We confirmed several expected associations with PGA in an acutely ill population. Crown Copyright © 2017. Published by Elsevier B.V. All rights reserved.

Patients with acute medical illnesses are at prolonged risk for venous thrombosis. However, the appropriate duration of thromboprophylaxis remains unknown. Patients who were hospitalized for acute medical illnesses were randomly assigned to receive subcutaneous enoxaparin (at a dose of 40 mg once daily) for 10±4 days plus oral betrixaban placebo for 35 to 42 days or subcutaneous enoxaparin placebo for 10±4 days plus oral betrixaban (at a dose of 80 mg once daily) for 35 to 42 days. We performed sequential analyses in three prespecified, progressively inclusive cohorts: patients with an elevated d-dimer level (cohort 1), patients with an elevated d-dimer level or an age of at least 75 years (cohort 2), and all the enrolled patients (overall population cohort). The statistical analysis plan specified that if the between-group difference in any analysis in this sequence was not significant, the other analyses would be considered exploratory. The primary efficacy outcome was a composite of asymptomatic proximal deep-vein thrombosis and symptomatic venous thromboembolism. The principal safety outcome was major bleeding. A total of 7513 patients underwent randomization. In cohort 1, the primary efficacy outcome occurred in 6.9% of patients receiving betrixaban and 8.5% receiving enoxaparin (relative risk in the betrixaban group, 0.81; 95% confidence interval [CI], 0.65 to 1.00; P=0.054). The rates were 5.6% and 7.1%, respectively (relative risk, 0.80; 95% CI, 0.66 to 0.98; P=0.03) in cohort 2 and 5.3% and 7.0% (relative risk, 0.76; 95% CI, 0.63 to 0.92; P=0.006) in the overall population. (The last two analyses were considered to be exploratory owing to the result in cohort 1.) In the overall population, major bleeding occurred in 0.7% of the betrixaban group and 0.6% of the enoxaparin group (relative risk, 1.19; 95% CI, 0.67 to 2.12; P=0.55). Among acutely ill medical patients with an elevated d-dimer level, there was no significant difference between extended

The objective of this study was to determine factors associated with ambulance requests for febrile seizures. This study retrospectively investigated medical records of patients who visited the Emergency Care Unit at Tokyo Metropolitan Toshima Hospital in the 5-year period after April 2001. Subjects' basic characteristics (e.g., age and sex), medical history of febrile seizures, sibling and parental medical history of febrile seizures, and distance from hospital were investigated. In total, 310 subjects used ambulances, and 106 came to the hospital without requesting ambulances. The results of binomial logistic analysis indicated that factors associated with ambulance requests included patient's and parents' medical history of febrile seizures. Increasing awareness of febrile seizures and provision of a general public educational campaign are possible strategies to help decrease unnecessary ambulance requests. However, a medical history of febrile seizures among siblings revealed no association, indicating the need to conduct repeated early-stage interventions.

To determine the prevalence of benign febrile seizures of childhood and describe the clinical and epidemiological profile of this population. This was a population-based, cross-sectional study, carried out in the city of Barra do Bugres, MT, Brazil, from August 2012 to August 2013. Data were collected in two phases. In the first phase, a questionnaire that was previously validated in another Brazilian study was used to identify suspected cases of seizures. In the second phase, a neurological evaluation was performed to confirm diagnosis. The prevalence was 6.4/1000 inhabitants (95% CI: 3.8-10.1). There was no difference between genders. Simple febrile seizures were found in 88.8% of cases. A family history of febrile seizures in first-degree relatives and history of epilepsy was present in 33.3% and 11.1% of patients, respectively. The prevalence of febrile seizures in Midwestern Brazil was lower than that found in other Brazilian regions, probably due to the inclusion only of febrile seizures with motor manifestations and differences in socioeconomic factors among the evaluated areas.

Acute necrotizing encephalopathy (ANE) is a rare but distinctive type of acute encephalopathy with global distribution. Occurrence of ANE is usually preceded by a virus-associated febrile illness and ensued by rapid deterioration. However, the causal relationship between viral infections and ANE and the exact pathogenesis of ANE remain unclear; both environmental and host factors might be involved. Most cases of ANE are sporadic and nonrecurrent, namely, isolated or sporadic ANE; however, few cases are recurrent and with familial episodes. The recurrent and familial forms of ANE were found to be incompletely autosomal-dominant. Further the missense mutations in the gene encoding the nuclear pore protein Ran Binding Protein 2 (RANBP2) were identified. Although the clinical course and the prognosis of ANE are diverse, the hallmark of neuroradiologic manifestation of ANE is multifocal symmetric brain lesions which are demonstrated by computed tomography (CT) or magnetic resonance imaging (MRI). The treatment of ANE is still under investigation. We summarize the up-to-date knowledge on ANE, with emphasis on prompt diagnosis and better treatment of this rare but fatal disease. PMID:25873770

Transportation of acutely or critically ill patients is a challenge for health care providers. Among the difficulties that providers face is the balance between adequate sedation and analgesia for the transportation event and maintaining acceptable respiratory and physiologic parameters of the patient. This article describes common challenges in providing sedation and analgesia during various phases of transport. Copyright © 2016 Elsevier Inc. All rights reserved.

Intensity of Renal Support in Critically Ill Patients with Acute Kidney Injury

PubMed Central

2008-01-01

BACKGROUND The optimal intensity of renal-replacement therapy in critically ill patients with acute kidney injury is controversial. METHODS We randomly assigned critically ill patients with acute kidney injury and failure of at least one nonrenal organ or sepsis to receive intensive or less intensive renal-replacement therapy. The primary end point was death from any cause by day 60. In both study groups, hemodynamically stable patients underwent intermittent hemodialysis, and hemodynamically unstable patients underwent continuous venovenous hemodiafiltration or sustained low-efficiency dialysis. Patients receiving the intensive treatment strategy underwent intermittent hemodialysis and sustained low-efficiency dialysis six times per week and continuous venovenous hemodiafiltration at 35 ml per kilogram of body weight per hour; for patients receiving the less-intensive treatment strategy, the corresponding treatments were provided thrice weekly and at 20 ml per kilogram per hour. RESULTS Baseline characteristics of the 1124 patients in the two groups were similar. The rate of death from any cause by day 60 was 53.6% with intensive therapy and 51.5% with less-intensive therapy (odds ratio, 1.09; 95% confidence interval, 0.86 to 1.40; P = 0.47). There was no significant difference between the two groups in the duration of renalreplacement therapy or the rate of recovery of kidney function or nonrenal organ failure. Hypotension during intermittent dialysis occurred in more patients randomly assigned to receive intensive therapy, although the frequency of hemodialysis sessions complicated by hypotension was similar in the two groups. CONCLUSIONS Intensive renal support in critically ill patients with acute kidney injury did not decrease mortality, improve recovery of kidney function, or reduce the rate of nonrenal organ failure as compared with less-intensive therapy involving a defined dose of intermittent hemodialysis three times per week and continuous renal

Introduction Unhealthy alcohol use predisposes to multiple conditions that frequently result in critical illness and is present in up to one-third of patients admitted to a medical intensive care unit (ICU). We sought to determine the baseline readiness to change in medical ICU patients with unhealthy alcohol use and hypothesized that the severity of acute illness would be independently associated with higher scores on readiness to change scales. We further sought to determine whether this effect is modified by the severity of unhealthy alcohol use. Materials and Methods We performed a cross-sectional observational study of current regular drinkers in three medical ICUs. The Alcohol Use Disorders Identification Test was used to differentiate low risk and unhealthy alcohol use and further categorize patients into risky alcohol use or an alcohol use disorder. The severity of a patient’s acute illness was assessed by calculating the Acute Physiology and Chronic Healthy Evaluation II score at the time of admission to the medical ICU. Readiness to change was assessed using standardized questionnaires. Results Of 101 medical ICU patients who were enrolled, 65 met the criteria for unhealthy alcohol use. The association between the severity of acute illness and readiness to change depended on the instrument used. A higher severity of illness measured by APACHEII score was an independent predictor of readiness to change as assessed by the Stages of Change Readiness and Treatment Eagerness Scale (Taking Action scale) (p< 0.01). When a visual analog scale was used to assess readiness to change, there was a significant association with severity of acute illness (p < 0.01) that was modified by the severity of unhealthy alcohol use (p = 0.04 for interaction term). Conclusion Medical ICU patients represent a population where brief interventions require further study. Studies of brief intervention should account for the severity of acute illness and the severity of unhealthy

Acute kidney injury may contribute to distant organ dysfunction. Few studies have examined kidney injury as a risk factor for delirium and coma. To examine whether acute kidney injury is associated with delirium and coma in critically ill adults. In a prospective cohort study of intensive care unit patients with respiratory failure and/or shock, we examined the association between acute kidney injury and daily mental status using multinomial transition models adjusting for demographics, nonrenal organ failure, sepsis, prior mental status, and sedative exposure. Acute kidney injury was characterized daily using the difference between baseline and peak serum creatinine and staged according to Kidney Disease Improving Global Outcomes criteria. Mental status (normal vs. delirium vs. coma) was assessed daily with the Confusion Assessment Method for the ICU and Richmond Agitation-Sedation Scale. Among 466 patients, stage 2 acute kidney injury was a risk factor for delirium (odds ratio [OR], 1.55; 95% confidence interval [CI], 1.07-2.26) and coma (OR, 2.04; 95% CI, 1.25-3.34) as was stage 3 injury (OR for delirium, 2.56; 95% CI, 1.57-4.16) (OR for coma, 3.34; 95% CI, 1.85-6.03). Daily peak serum creatinine (adjusted for baseline) values were also associated with delirium (OR, 1.35; 95% CI, 1.18-1.55) and coma (OR, 1.44; 95% CI, 1.20-1.74). Renal replacement therapy modified the association between stage 3 acute kidney injury and daily peak serum creatinine and both delirium and coma. Acute kidney injury is a risk factor for delirium and coma during critical illness.

Sudden unexplained death in toddlers has been associated with febrile seizures, family history of febrile seizures, and hippocampal anomalies. We investigated the mode of inheritance for febrile seizures in these families. A three-generation pedigree was obtained from families enrolled in the San Diego Sudden Unexplained Death in Childhood Research Project, involving toddlers with sudden unexplained death, febrile seizures, and family history of febrile seizures. In our six cases, death was unwitnessed and related to sleep. The interval from last witnessed febrile seizure to death ranged from 3 weeks to 6 months. Hippocampal abnormalities were identified in one of three cases with available autopsy sections. Autosomal dominant inheritance of febrile seizures was observed in three families. A fourth demonstrated autosomal dominant inheritance with incomplete penetrance or variable expressivity. In two families, the maternal and paternal sides manifested febrile seizures. In this series, the major pattern of inheritance in toddlers with sudden unexplained death and febrile seizures was autosomal dominant. Future studies should develop markers (including genetic) to identify which patients with febrile seizures are at risk for sudden unexplained death in childhood, and to provide guidance for families and physicians.

To summarize the current literature on racial and gender disparities in critical care and the mechanisms underlying these disparities in the course of acute critical illness. MEDLINE search on the published literature addressing racial, ethnic, or gender disparities in acute critical illness, such as sepsis, acute lung injury, pneumonia, venous thromboembolism, and cardiac arrest. Clinical studies that evaluated general critically ill patient populations in the United States as well as specific critical care conditions were reviewed with a focus on studies evaluating factors and contributors to health disparities. Study findings are presented according to their association with the prevalence, clinical presentation, management, and outcomes in acute critical illness. This review presents potential contributors for racial and gender disparities related to genetic susceptibility, comorbidities, preventive health services, socioeconomic factors, cultural differences, and access to care. The data are organized along the course of acute critical illness. The literature to date shows that disparities in critical care are most likely multifactorial involving individual, community, and hospital-level factors at several points in the continuum of acute critical illness. The data presented identify potential targets as interventions to reduce disparities in critical care and future avenues for research.

It is important that mental health nurses meet the safety, security and care needs of persons suffering from psychotic illness to enhance these persons' likelihood of feeling better during their time in acute psychiatric wards. Certain persons in care describe nurses' mental health care as positive, whereas others report negative experiences and express a desire for improvements. There is limited research on how persons with psychotic illness experience nurses' mental health care acts and how such acts help these persons feel better. Therefore, the aim of this study was to explore, describe and understand how the mental health nurses in acute psychiatric wards provide care that helps persons who experienced psychotic illness to feel better, as narrated by these persons. This study had a qualitative design; 12 persons participated in qualitative interviews. The interviews were transcribed, content analysed and interpreted using Martin Buber's concept of confirmation. The results of this study show three categories of confirming mental health care that describe what helped the participants to feel better step-by-step: first, being confirmed as a person experiencing psychotic illness in need of endurance; second, being confirmed as a person experiencing psychotic illness in need of decreased psychotic symptoms; and third, being confirmed as a person experiencing psychotic illness in need of support in daily life. The underlying meaning of the categories and of subcategories were interpreted and formulated as the theme; confirming mental health care to persons experiencing psychotic illness. Confirming mental health care acts seem to help persons to feel better in a step-wise manner during psychotic illness. Nurses' openness and sensitivity to the changing care needs of persons who suffer from psychotic illness create moments of confirmation within caring acts that concretely help the persons to feel better and that may enhance their health. The results show the

Recent studies have shown the prophylactic efficacy of fluoroquinolones against infections in patients with chemotherapy-induced neutropenia. However, little is known about the differences between fluoroquinolones, and there are some concerns about the emergence of resistant bacteria. In this retrospective study, we compared the prophylactic efficacy of moxifloxacin (MFLX) and tosufloxacin (TFLX) for chemotherapy-induced febrile neutropenia. The cumulative incidences of febrile neutropenia were 74.7% (59 of 79) in the MFLX group and 81.1% (219 of 270) in the TFLX group (log-rank test p = 0.044). Subgroup analysis revealed a more prominent prophylactic advantage of MFLX in patients with acute myeloid leukemia (AML) or long duration of neutropenia (p = 0.013 and 0.008, respectively). There were no significant differences in the incidences of adverse events and fluoroquinolone resistant bacteria in both groups. This study indicates that prophylaxis with MFLX is more beneficial to reduce febrile neutropenia episodes than TFLX, especially in patients with high-risk disease.

Background International travel continues to increase, particularly to Asia and Africa. Clinicians are increasingly likely to be consulted for advice before travel or by ill returned travelers. Objective To describe typical diseases in returned travelers according to region, travel reason, and patient demographic characteristics; describe the pattern of low-frequency travel-associated diseases; and refine key messages for care before and after travel. Design Descriptive, using GeoSentinel records. Setting 53 tropical or travel disease units in 24 countries. Patients 42 173 ill returned travelers seen between 2007 and 2011. Measurements Frequencies of demographic characteristics, regions visited, and illnesses reported. Results Asia (32.6%) and sub-Saharan Africa (26.7%) were the most common regions where illnesses were acquired. Three quarters of travel-related illness was due to gastrointestinal (34.0%), febrile (23.3%), and dermatologic (19.5%) diseases. Only 40.5% of all ill travelers reported pretravel medical visits. The relative frequency of many diseases varied with both travel destination and reason for travel, with travelers visiting friends and relatives in their country of origin having both a disproportionately high burden of serious febrile illness and very low rates of advice before travel (18.3%). Life-threatening diseases, such as Plasmodium falciparum malaria, melioidosis, and African trypanosomiasis, were reported. Limitations Sentinel surveillance data collected by specialist clinics do not reflect healthy returning travelers or those with mild or self-limited illness. Data cannot be used to infer quantitative risk for illness. Conclusion Many illnesses may have been preventable with appropriate advice, chemoprophylaxis, or vaccination. Clinicians can use these 5-year GeoSentinel data to help tailor more efficient pretravel preparation strategies and evaluate possible differential diagnoses of ill returned travelers according to destination and

Febrile neutropenia may be a sign of severe infection, and is associated with significant morbidity and mortality in high-risk patients with hematologic malignancies. Extended infusion of β-lactam antibiotics is associated with greater clinical response than is bolus infusion in non-neutropenic critically ill patients, but data are lacking for febrile neutropenic patients. We designed a single-center, non-blinded randomized trial comparing extended infusion (4 hours) and bolus infusion (30 minutes) of piperacillin-tazobactam or ceftazidime in high-risk patients with febrile neutropenia. The primary end-point was overall response on day 4, defined as the combination of resolution of fever, sterile blood cultures, resolution of clinical signs and symptoms, and no need for a change in the antibiotic regimen. Outcome was adjudicated by investigators blinded to treatment allocation. Of 123 enrolled patients, 105 had febrile neutropenia and were included in the intention-to-treat analysis: 47 in the extended infusion arm and 58 in the bolus infusion arm. Overall response occurred in 35 (74.4%) patients treated with extended infusion and 32 (55.1%) patients treated with bolus infusion (P=0.044). The superiority of extended infusion compared with bolus infusion was greatest for patients with clinically documented infections (overall response, 68.4% [13/19] versus 35.7% [10/28]; P=0.039), and specifically for those with pneumonia (80% [4/5] versus 0% [0/8]; P=0.007). Extended infusion of β-lactams is associated with superior treatment outcomes as compared with bolus infusion for high-risk patients with febrile neutropenia. The benefit of extended β-lactam infusion may be greatest for patients with pulmonary infections.

The drinking water infrastructure in the United States is ageing; extreme weather events place additional stress on water systems that can lead to interruptions in the delivery of safe drinking water. We investigated the association between household exposures to water service problems and acute gastrointestinal illness (AGI) and acute respiratory illness (ARI) in Alabama communities that experienced a freeze-related community-wide water emergency. Following the water emergency, investigators conducted a household survey. Logistic regression models were used to estimate adjusted prevalence ratios (aPR) and 95% confidence intervals (CI) for self-reported AGI and ARI by water exposures. AGI was higher in households that lost water service for ⩾7 days (aPR 2·4, 95% CI 1·1-5·2) and experienced low water pressure for ⩾7 days (aPR 3·6, 95% CI 1·4-9·0) compared to households that experienced normal service and pressure; prevalence of AGI increased with increasing duration of water service interruptions. Investments in the ageing drinking water infrastructure are needed to prevent future low-pressure events and to maintain uninterrupted access to the fundamental public health protection provided by safe water supplies. Households and communities need to increase their awareness of and preparedness for water emergencies to mitigate adverse health impacts.

Management of chemotherapy-associated febrile neutropenia.

PubMed

Cameron, D

2009-09-01

The development of febrile neutropenia during a course of chemotherapy is not only a life-threatening complication, it can also lead to a decision to reduce chemotherapy intensity in subsequent treatment cycles, thus putting patient outcomes at risk. Although there are strategies available for the primary prevention of febrile neutropenia, these are not widely used in the UK management of breast cancer. It is, therefore, paramount to have a well thought out and rigorously implemented care protocol for febrile neutropenia, involving patients, family/carers and health-care professionals in both primary and secondary care, to ensure early detection and effective management.

An epidemic of rash and fever illnesses suspected of hand, foot and mouth disease (HFMD) occurred in Gansu Province of China in 2008, laboratory tests were performed in order to identify the pathogen that caused this epidemic. Eight clinical specimens collected from the 4 patients (each patient has throat swab and herpes fluid specimens) with rash and febrile illness, were inoculated onto RD and HEp-2 cells for virus isolation, and the viral nucleic acid was then extracted with the positive virus isolates, the dual-channel real-time reverse transcript-polymerase chain reaction (RT-PCR) was performed to detect the nucleic acid of human enterovirus (HEV) in the viral isolates at the same time. For the viral isolates with the negative results of HEV, a sequence independent single primer amplification technique (SISPA) was used for "unknown pathogen" identification. Totally, 6 viral isolates were identified as herpes simplex virus type 1 (HSV-1). Comprehensive analyses results of the clinical manifestations of the patients, epidemiological findings and laboratory test indicated that this epidemic of rash and febrile illness was caused by HSV-1. The differences among the gG region of 6 HSV-1 isolates at nucleotide level and amino acid level were all small, and the identities were up to 98. 8% and 97.9%, respectively, showing that this outbreak was caused by only one viral transmission chain of HSV-1. HSV-1 and other viruses that cause rash and febrile illnesses need differential diagnosis with HFMD. The etiology of rash and febrile illness is sometimes difficult to distinguish from the clinical symptoms and epidemiological data, the laboratory diagnosis is therefore critical.

Hospitalists and others acute-care providers are limited by gaps in evidence addressing the needs of the acutely ill older adult population. The Society of Hospital Medicine sponsored the Acute Care of Older Patients Priority Setting Partnership to develop a research agenda focused on bridging this gap. Informed by the Patient-Centered Outcomes Research Institute framework for identification and prioritization of research areas, we adapted a methodology developed by the James Lind Alliance to engage diverse stakeholders in the research agenda setting process. The work of the Partnership proceeded through 4 steps: convening, consulting, collating, and prioritizing. First, the steering committee convened a partnership of 18 stakeholder organizations in May 2013. Next, stakeholder organizations surveyed members to identify important unanswered questions in the acute care of older persons, receiving 1299 responses from 580 individuals. Finally, an extensive and structured process of collation and prioritization resulted in a final list of 10 research questions in the following areas: advanced-care planning, care transitions, delirium, dementia, depression, medications, models of care, physical function, surgery, and training. With the changing demographics of the hospitalized population, a workforce with limited geriatrics training, and gaps in evidence to inform clinical decision making for acutely ill older patients, the identified research questions deserve the highest priority in directing future research efforts to improve care for the older hospitalized patient and enrich training. © 2015 Society of Hospital Medicine.

The ultimate therapy for acute cholecystitis is cholecystectomy. However, in critically ill elderly patients the mortality of emergency cholecystectomy may reach up to 30%. Open cholecystostomy performed under local anesthesia was considered to be the procedure of choice for treatment of acute cholecystitis in high-risk patients. In recent years, ultrasound- or computed tomography (CT)-guided percutaneous transhepatic cholecystostomy (PTHC) replaced open cholecystostomy for the treatment of acute cholecystitis in critically ill patients. The aim of the present study was to evaluate the results of a 5-year protocol using PTHC followed by delayed laparoscopic cholecystectomy for the treatment of acute cholecystitis in critically ill patients. We reviewed the charts of 55 patients who underwent PTHC at the Hadassah University Hospital Mount Scopus during the years 1994 to 1999. The main indications for PTHC among this group of severely sick and high-risk patients was biliary sepsis and septic shock in 23 patients (42%); and severe comorbidities in 32 patients (58%). The median age was 74 (32 to 98) years, 33 were female and 22 male. Successful biliary drainage by PTHC was achieved in 54 of 55 (98%) of the patients. The majority of the patients (31 of 55) were drained transhepaticlly under CT guidance. The rest, (24 of 55) were drained using ultrasound guidance followed by cholecystography for verification. Complications included hepatic bleeding that required surgical intervention in 1 patient and dislodgment of the catheter in 9 patients that was reinserted in 2 patients. Three patients died of multisystem organ failure 12 to 50 days following the procedure. The remaining 52 patients recovered well with a mean hospital stay of 15.5 plus minus 11.4 days. Thirty-one patients were able to undergo delayed surgery: 28 underwent laparoscopic cholecystectomy of whom 4 (14%) were converted to open cholecystectomy.

We reported a girl with HHV-6 infection associated with both acute encephalopathy with biphasic seizures and late reduced diffusion, and hemophagocytic syndrome. She had a prolonged convulsion after a one-day history of febrile illness. Cerebrospinal fluid or brain CT showed no abnormalities on admission and her consciousness was recovered on the next day. However, a prolonged seizure and deterioration of consciousness appeared on the sixth day of illness. Diffusion-weighted images revealed marked reduction of water diffusion in the bilateral frontal areas. HHV-6 infection was virologically proven by polymerase chain reaction. She was treated with gamma-globulin, steroid pulse therapy, and brain hypothermia. In addition, decrease in white blood cells and platelet counts, and elevation of liver enzymes and ferritin were noted on the fourth day of illness. Hemophagocytic macrophages were revealed by bone marrow aspiration on the sixth day. Her hematological and blood chemistry abnormalities recovered gradually after steroid pulse therapy. An elevation of interleukin-6, -8, and -10, and tumor necrosis factor in the serum and that of interleukin-4, -6, and-8 in the cerebrospinal fluid were observed at the onset of a late seizure. These facts suggested that hypercytokinemia will be related to the pathogenesis of acute encephalopathy of our patient. Copyright (c) 2009 Elsevier B.V. All rights reserved.

Purpose To determine prevalence and risk factors for renal scar in children referred for urologic assessment of febrile UTI and/or VUR. Methods Pre-determined risk factors for renal scar were prospectively recorded in consecutive patients referred for UTI/VUR. Age, gender, VUR grade, and reported number of febrile and non-febrile UTIs were analyzed with logistic regression to determine risk for focal cortical defects on non-acute DMSA. Results Of 565 consecutive children, 24 (4%) had congenital renal dysplasia and 84 (15.5%) had focal defect(s). VUR, especially grades IV–V, recurrent febrile UTI, and older age increased risk. For any age child with the same number of UTIs, VUR increased odds of renal defect 5.4-fold (OR = 5.4, 95% CI = 2.7–10.6, AUC = 0.759). Conclusions Focal DMSA defects were present in 15.5% of 565 consecutive children referred for febrile UTI and/or VUR; 4% had presumed congenital reflux nephropathy without cortical defect. All VUR grades increased risk for these defects, as did recurrent febrile UTIs and older age. However, 43% with grades IV–V VUR and 76% with recurrent UTI had normal DMSA. PMID:23465483

A simultaneous decline in pro- and anticoagulant drivers in patients with liver diseases results in a 'rebalanced' hemostatic system, even in acutely ill patients. Nevertheless, both bleeding and thrombotic events are common. Here, we explored efficacy of pro- and antihemostatic strategies in compensated and acutely ill cirrhotics which may be unpredictable given the profound hemostatic changes. We tested the effects in vitro of the addition of clinically relevant doses of commonly used pro- and antihemostatic strategies in plasma from healthy individuals (n=30) and patients with compensated (n=18) and acutely decompensated cirrhosis (n=18), and acute-on-chronic liver failure (n=10). We used thrombin generation tests and fibrin clot permeability assays to assess potency of various approaches. Fresh frozen plasma and recombinant factor VIIa modestly increased thrombin generation (10-20%). Prothrombin complex concentrate increased thrombin generation 2-fold in controls and 2-4-fold in patients. Clot permeability decreased after addition of fibrinogen concentrate by 51% in controls and by 50-60% in patients. Low molecular weight heparin decreased thrombin generation by 18% in controls and by 23-54% in patients. Similarly, dabigatran decreased thrombin generation by 33% in controls and by 47-100% in patients. In contrast, rivaroxaban decreased thrombin generation by 55% in controls, but only by 11-38% in patients. These in vitro data suggest little prohemostatic effect of fresh frozen plasma and recombinant factor VIIa in acutely ill cirrhotics, whereas prothrombin complex concentrate and fibrinogen concentrate clearly improved hemostasis. Furthermore, our data suggest the requirement for dose-adjustments of commonly used anticoagulants in these patients. This article is protected by copyright. All rights reserved.

Background For older adults, hospitalization frequently results in deterioration of mobility and function. Nevertheless, there are little data about how older adults exercise in the hospital and definitive studies are not yet available to determine what type of physical activity will prevent hospital related decline. Strengthening exercise may prevent deconditioning and Pilates exercise, which focuses on proper body mechanics and posture, may promote safety. Methods A hospital-based resistance exercise program, which incorporates principles of resistance training and Pilates exercise, was developed and administered to intervention subjects to determine whether acutely-ill older patients can perform resistance exercise while in the hospital. Exercises were designed to be reproducible and easily performed in bed. The primary outcome measures were adherence and participation. Results Thirty-nine ill patients, recently admitted to an acute care hospital, who were over age 70 [mean age of 82.0 (SD= 7.3)] and ambulatory prior to admission, were randomized to the resistance exercise group (19) or passive range of motion (ROM) group (20). For the resistance exercise group, participation was 71% (p = 0.004) and adherence was 63% (p = 0.020). Participation and adherence for ROM exercises was 96% and 95%, respectively. Conclusion Using a standardized and simple exercise regimen, selected, ill, older adults in the hospital are able to comply with resistance exercise. Further studies are needed to determine if resistance exercise can prevent or treat hospital-related deterioration in mobility and function. PMID:14531932

Objective To summarize the current literature on racial and gender disparities in critical care and the mechanisms underlying these disparities in the course of acute critical illness. Data Sources MEDLINE search on the published literature addressing racial, ethnic, or gender disparities in acute critical illness such as sepsis, acute lung injury, pneumonia, venous thromboembolism, and cardiac arrest. Study Selection Clinical studies that evaluated general critically ill patient populations in the United States as well as specific critical care conditions were reviewed with a focus on studies evaluating factors and contributors to health disparities. Data Extraction Study findings are presented according to their association with the incidence, clinical presentation, management, and outcomes in acute critical illness. Data Synthesis This review presents potential contributors for racial and gender disparities related to genetic susceptibility, comorbidities, preventive health services, socioeconomic factors, cultural differences, and access to care. The data is organized along the course of acute critical illness. Conclusions The literature to date shows that disparities in critical care are most likely multifactorial involving individual, community, and hospital-level factors at several points in the continuum of acute critical illness. The data presented identify potential targets as interventions to reduce disparities in critical care and future avenues for research. PMID:24121467

Extended thromboprophylaxis in the acutely ill medical patient after hospitalization - a paradigm shift in post-discharge thromboprophylaxis.

Mahan, Charles E; Burnett, Allison E; Fletcher, Meghan L; Spyropoulos, Alex C

2018-02-01

Venous thromboembolism (VTE) is a significant healthcare burden with approximately 900,000 events annually in the United States, over half of which are healthcare-associated. This number is anticipated to double by 2050. Group prophylaxis strategies confined to the inpatient setting appear to have minimal impact on the reduction of post-discharge VTE in medically ill patients due to shortened lengths of stay and a heterogenous population that includes patients at low risk for VTE. In accordance with current guideline recommendations, very few (<5%) medically ill patients are discharged with extended prophylaxis, which potentially creates a clinical gap for at-risk patients as VTE risk has been shown to persist for up to 90 days. Initial studies of extended thromboprophylaxis in acutely ill medical patients with enoxaparin, rivaroxaban and apixaban showed little to no benefit towards VTE reduction that was consistently outweighed by increased bleeding. The more recent APEX study that compared betrixaban to enoxaparin in an enriched patient population at high-risk for VTE was the first study of extended thromboprophylaxis that showed similar efficacy in VTE prevention without an increase in major bleeding. Based on the APEX results, betrixaban recently gained FDA approval for extended thromboprophylaxis in acutely ill medical patients. Recognition that up to half of medically ill patients are not at sufficient risk to warrant thromboprophylaxis has driven extensive research towards development of scientifically derived and validated VTE risk assessment models intended to identify patients who do not warrant prophylaxis, as well as those at high risk who may derive benefit from extended thromboprophylaxis. This article will review prior and ongoing extended thromboprophylaxis studies, VTE and bleed risk assessment models, incorporation of biomarkers in VTE risk assessment and key issues in the paradigm shift towards individualized VTE prophylaxis in acutely ill

Abraham Lincoln's Gettysburg illness.

PubMed

Goldman, Armond S; Schmalstieg, Frank C

2007-05-01

When Abraham Lincoln delivered the Gettysburg Address, he was weak and dizzy; his face had a ghastly colour. That evening on the train to Washington, DC, he was febrile and weak, and suffered severe headaches. The symptoms continued; back pains developed. On the fourth day of the illness, a widespread scarlet rash appeared that soon became vesicular. By the tenth day, the lesions itched and peeled. The illness lasted three weeks. The final diagnosis, a touch of varioloid, was an old name for smallpox that was later used in the 20th century to denote mild smallpox in a partially immune individual. It was unclear whether Lincoln had been immunized against smallpox. Indeed, this review suggests that Lincoln had unmodified smallpox and that Lincoln's physicians tried to reassure the public that Lincoln was not seriously ill. Indeed, the successful conclusion of the Civil War and reunification of the country were dependent upon Lincoln's presidency.

Outpatient management of febrile neutropenia: time to revise the present treatment strategy.

We reviewed medical literature on the efficacy and safety of outpatient versus hospital-based therapy of low-risk febrile neutropenia in adult cancer patients. A PubMed search for all studies evaluating the outpatient treatment of adults diagnosed with solid tumors who suffered from low-risk febrile neutropenia was completed; reference lists from identified articles also were used. In all, 10 trials were included in the analysis, which showed no significant difference in clinical failure rates and mortality for ambulatory regimens and standard hospital-based therapy. Subgroup analysis according to the type of fever episode showed no significant differences in clinical failure rates for fever of unknown origin and fever due to documented infections. Subgroup analyses in two independent trials identified an absolute neutrophil count < 100 cells/ mm3 as being predictive of outpatient treatment failure (P < 0.04). These findings need to be confirmed by further trials. Thus, outpatient management of adult cancer patients with low-risk febrile neutropenia is safe, effective, and comparable to standard hospital-based therapy. Patients at low risk are outpatients and are hemodynamically stable; they have no organ failure, they are able to take oral medications, and they do not suffer from acute leukemia. Low-risk prediction also may be based on the Multinational Association for Supportive Care in Cancer risk index.

On May 21, 1997, numerous cases of febrile gastrointestinal illness were reported among the students and staff of two primary schools in northern Italy, all of whom had eaten at cafeterias served by the same caterer. We interviewed people who ate at the cafeterias about symptoms and foods consumed on May 20. There were no samples of foods left at the cafeterias, but we tested routine samples taken on May 20 by the caterer and environmental specimens at the catering plant. The hospitalized patients were tested for common enteropathogens and toxins. Of the 2189 persons interviewed (82 percent of those exposed), 1566 (72 percent) reported symptoms; of these, 292 (19 percent) were hospitalized. Among samples obtained from hospitalized patients, all but two of the stool specimens and all blood specimens were negative for common enteropathogens. Listeria monocytogenes was isolated from one blood specimen and from 123 of the 141 stool specimens. Consumption of a cold salad of corn and tuna was associated with the development of symptoms (relative risk, 6.19; 95 percent confidence interval, 4.81 to 7.98; P<0.001). L. monocytogenes was isolated from the caterer's sample of the salad and from environmental specimens collected from the catering plant. All listeria isolates were serotype 4b and were found to be identical on DNA analysis. Experimental contamination of sterile samples of the implicated foods showed that L. monocytogenes grew on corn when kept for at least 10 hours at 25 degrees C. Food-borne infection with L. monocytogenes can cause febrile illness with gastroenteritis in immunocompetent persons.

Heterologous secondary infections are at increased risk of developing dengue hemorrhagic fever (DHF) because of antibody-dependent enhancement (ADE). IgG subclasses can fix and activate complement and bind to Fcɣ receptors. These factors may also play an important role in the development of ADE and thus in the pathogenesis of DHF. The aim of this study was to analyze the indices of anti-dengue IgG subclasses in adult patients with febrile and hemorrhagic dengue in the acute phase. In 2013, 129 patients with dengue fever (DF) and 57 with DHF in Veracruz, Mexico were recruited for this study and anti-dengue IgM and IgG determined by capture ELISA. Anti-dengue IgG subclasses were detected by indirect ELISA. Anti-dengue IgG2 and IgG3 subclasses were detected in patients with dengue. IgG1 increased significantly in the sera of patients with both primary and secondary infections and DHF, but was higher in patients with secondary infections. The IgG4 subclass index was significantly higher in the sera of patients with DHF than in that of those with DF, who were in the early and late acute phase of both primary and secondary infection. In conclusion, indices of subclasses IgG1 and IgG4 were higher in patients with DHF. © 2017 The Societies and John Wiley & Sons Australia, Ltd.

Acute encephalopathy has the possibility of sequelae. While early treatment is required to prevent the development of sequelae, differential diagnosis is of the utmost priority. The aim of this study was therefore to identify parameters that can facilitate early diagnosis and prediction of outcome of acute encephalopathy. We reviewed the medical charts of inpatients from 2005 to 2011 and identified 33 patients with febrile status epilepticus. Subjects were classified into an acute encephalopathy group (n = 20) and a febrile convulsion group (n = 13), and the parameters serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), lactate dehydrogenase (LDH), ammonia (NH 3 ), cerebrospinal fluid (CSF) tau protein, and CSF interleukin-6 compared between them. Furthermore, the relationship between each parameter and prognosis was investigated in the encephalopathy group. Significant differences in serum AST, ALT, and LDH were observed between the febrile convulsion and acute encephalopathy group. Moreover, a significant difference in serum LDH was noted between the patients with and without developmental regression at the time of hospital discharge in the encephalopathy group. In particular, CSF tau protein was found to be highly likely to indicate progress, with CSF tau protein >1000 pg/dL associated with poor prognosis leading to developmental regression. Serum AST, ALT and LDH may be related to early diagnosis and prognosis, and should be carefully investigated in patients with encephalopathy. CSF tau protein could also be used as an indicator of poor prognosis in acute encephalopathy. © 2016 Japan Pediatric Society.

Isotonic saline is recommended as maintenance intravenous fluid therapy (MIVFT) for most of the acutely ill hospitalized children. The aim of this study is to assess the current knowledge of paediatric residents regarding the selection of MIVFT in hospitalized children. We conducted a paper-based questionnaire survey to paediatric residents from ten centres asking selection of MIVFT in four common clinical scenarios in 6-month and 10-year old patients as well as monitoring of fluid balance and electrolyte. 445 responses were collected (>90% response rate). Majority [78.3% (n=348)] of them were FCPS-trainees. The 0.9%, 0.45% and 0.2% solution were selected by 45.8%, 43.98% and 10.92% respectively. The isotonic and hypotonic solution was prescribed in 6- mo (35.22% vs. 64.76% [p<0.001]) and 10-year (54.49% vs. 44.98%) in four different clinical scenarios respectively. 0.45% solution was most commonly prescribed MIVFT in pneumonia (50.22%) and meningitis (45.39%) and 0.9% solution was most commonly selected in acute gastroenteritis (55.05%) and post-operative patients (51.23%). Fluid balance and electrolyte monitoring were selected by 96.9% and 55.7% respondents respectively. Our survey reports that more than fifty percent of paediatric residents have inadequate knowledge about maintenance intravenous fluid therapy in acutely ill hospitalized children.

Febrile neutropenia (FN) is an important cause of morbidity and mortality in children with acute lymphoblastic leukemia (ALL). We aimed to look at complications in febrile neutropenia and to derive a risk model for developing complications from the variables predicting complications. Children on treatment for ALL, presenting with FN, were prospectively enrolled over a period of 1 year. Their clinical presentation, course during hospital stay, and outcomes were recorded. Complications recorded included septic shock, pneumonia requiring invasive or non-invasive ventilation, renal failure, neutropenic enterocolitis, encephalopathy, congestive heart failure, and bleeding manifestations. There were 320 episodes of FN among 176 patients. Complications occurred during 73 (22.8%) episodes. Time since last chemotherapy ≤7 days [OR 2.2 (1-4.5)], clinical focus of infection [OR 2.7 (1.3-5.5)], undernutrition [OR 2.5 (1.1-5.5)], absolute neutrophil count (ANC) ≤ 100/μL [OR 2.8 (1.3-5.9)], and C-reactive protein (CRP) > 60 mg/L at admission [OR 13.3 (5.2-33.8)] were independent predictors of complications. A risk model (total score = 13) was developed based on these predictors. Children with score of ≥7 had 17.2 (7.7-38.6) odds of developing complications as compared to those with score <7. Score of <7 predicted children at lower risk of complications [sensitivity 88% (78.2-93.8%), specificity 72.5% (65.7-78.4%), PPV 53.6% (44.3-62.6%), NPV 94.4% (89.3-97.1%)]. Complications during febrile neutropenia are high in a developing country setup. A risk score model based on identified risk factors can possibly help in recognizing low-risk febrile neutropenic children at admission.

Military personnel deployed in field actvities report on frequent tick bites. Therefore they may run the risk of exposure to rickettsial organisms. In order to assess the risk of exposure to rickettsial organisms, two groups of military personnel who were deployed in field activities of Nothern Sri Lanka were investigated. The first group was studied in order to assess the sero-prevalence of rickettsioses and consisted of soldiers who were admitted following injuries during field activities. The second group was studied to identify the incidence of acute rickettsioses during their acute febrile presentations. They were tested with IFA-IgG against spotted fever group rickettsioses (SFG), scrub typhus (ST) and murine typhus. In the first group, 48/57 (84%) military personnel had serological evidence of exposure to rickettsioses (in all, IFA-IgG titer ≥ 1:128): 33/50 (66%) to SFG rickettsioses, 1/50 (2%) to ST and 14/50 (28%) had mixed titers for both (in all, titers were higher for SFG). While all of them were in military uniform most of the time and frequently slept on scrub land, 35/57 (61.4%) had never used insect repellents and none were on doxycycline prophylaxis. 48/57 (84%) had experienced tick bites during field activity. In the second group, there were 49 who presented with acute febrile illness with a mean duration of 8.5 days (SD 3.2). 33/49 (67.3%) were serologically positive for acute rickettsioses (IgG ≥1:256); 26 (79%) due to ST and 7 (21%) due to SFG rickettsioses, Exposure to rickettsial disease was common among soldiers who were deployed in Northern Sri Lanka. Scrub typhus was the predominent species accounting for acute febrile illness. Further studies are needed to understand the reasons for very high sero-prevalence for SFG rickettsioses with no anticedent febrile illness. Use of preventive measures was not satisfactory. The high sero-prevelence of SFG rickettsioses is likely to interfere with serological diagnosis of acute SFG

This study compared acutely ill patients with schizophrenia with a history of self-harm (N=17) to those without a history of self-harm (N=16) on measures of depression, hopelessness, suicidal ideation, and demographic and psychiatric variables. A subgroup of these patients who experience auditory hallucinations, with and without a history of self-harm, were selected and compared on measures of depression, hopelessness, suicidal ideation and beliefs about voices. Employing a cross-sectional design, in-patients of two local psychiatric hospital, who met DSM-IV-TR criteria for schizophrenia and who were in an acute phase of the illness, were selected. Each patient was assessed using the Beck Depressions Inventory (BDI), Beck Hopelessness Scale (BHS) and the Beck Suicide Scale (BSS). Patients who experienced auditory verbal hallucinations completed the Beliefs About Voices Questionnaire Revised (BAVQ-R). Patients with a history of self-harm completed the Beck Suicide Intent Scale (BSI). Patients with a history of self-harm (N=17) had significantly greater symptoms of depression, greater suicidal thoughts, increased number of hospital admissions, greater duration of illness and were more likely to be married, compared to patients without a history of self-harm (N=16). Among the subgroup of patients who experience auditory hallucinations, those with a history of self-harm (N=9), believed their voice to be more malevolent, had a tendency to resist their voice and experienced significantly greater symptoms of depression and hopelessness compared to those without a history of self-harm (N=6). These findings highlight the importance for screening by clinicians during inpatient hospital stays and for monitoring to be ongoing following discharge. For the subgroup of patients who experience auditory hallucinations, future research should seek to explore the relationship between self-harm and beliefs about voices.

Introduction Albumin administration in the critically ill has been the subject of some controversy. We investigated the use of albumin solutions in European intensive care units (ICUs) and its relationship to outcome. Methods In a cohort, multicenter, observational study, all patients admitted to one of the participating ICUs between 1 May and 15 May 2002 were followed up until death, hospital discharge, or for 60 days. Patients were classified according to whether or not they received albumin at any time during their ICU stay. Results Of 3,147 admitted patients, 354 (11.2%) received albumin and 2,793 (88.8%) did not. Patients who received albumin were more likely to have cancer or liver cirrhosis, to be surgical admissions, and to have sepsis. They had a longer length of ICU stay and a higher mortality rate, but were also more severely ill, as manifested by higher simplified acute physiology score (SAPS) II and sequential organ failure assessment (SOFA) scores than the other patients. A Cox proportional hazard model indicated that albumin administration was significantly associated with decreased 30-day survival. Moreover, in 339 pairs matched according to a propensity score, ICU and hospital mortality rates were higher in the patients who had received albumin than in those who had not (34.8 versus 20.9% and 41.3 versus 27.7%, respectively, both p < 0.001). Conclusion Albumin administration was associated with decreased survival in this population of acutely ill patients. Further prospective randomized controlled trials are needed to examine the effects of albumin administration in sub-groups of acutely ill patients. PMID:16356223

Dengue is a mosquito-borne and neglected tropical viral disease that has been reported to be hyper-endemic in Nigeria. However, this is the first dengue study in Abuja. This hospital-based cross-sectional study investigated the prevalence of Dengue virus (DENV) non-structural protein-1 (NS1) antigenaemia, anti-Dengue virus IgG and their associated risk factors among febrile patients attending the University of Abuja Teaching Hospital (UATH), Nigeria. From May to August 2016, blood samples were individually collected from 171 consented participants. These samples were analyzed using DENV NS1 and anti-DENV IgG Enzyme Linked Immunosorbent Assay (ELISA) kits. Well-structured questionnaires was used to collect sociodemographic variables of participants. Out of the 171 participants, the prevalence of Dengue virus NS1 antigenaemia and IgG seropositivity were 8.8% and 43.3%, respectively. Three (1.8%) of the patients were NS1 (+) IgG (-), 12 (7.0%) had NS1 (+) IgG (+), 62 (36.3%) were NS1 (-) IgG (+), while 97 (56.7%) of the remaining patients were NS1 (-) IgG (-). There was statistical association between DENV NS1 antigenaemia with age of patients (p=0.034), residence in proximity to waste dumpsites (p<0.0001) but not with occupation of patients (p=0.166), use of indoor insecticide sprays (p=0.4910) and presence of household artificial water containers (p=0.3650). There was statistical association between the prevalence of anti-Dengue virus IgG with occupation (p=0.0034) and education level of patients (p<0.001). However, there was no statistical association between the prevalence of anti-Dengue virus IgG with gender (p=0.4060) and residential area of patients (p=0.3896). Findings from this study revealed that DENV infection is one of the etiological agents of acute febrile illnesses in Abuja. It's recommended that Dengue testing be considered during differential diagnosis of febrile patients. Copyright © 2016 Elsevier B.V. All rights reserved.

Acute kidney injury (AKI) is a common and serious complication in patients in the Pediatric Intensive Care Unit (PICU). We conducted this study to estimate the incidence and the mortality rate of AKI in critically ill children as well as to describe some other related factors. A retrospective study was conducted at PICU of Queen Rania Abdulla Children Hospital, Amman, Jordan for the period extending from May 2011 to June 2013. The medical records of all patients admitted during this period, and their demographic data were reviewed. Patients with AKI were identified, and management and outcomes were reviewed and analyzed. AKI was evaluated according to modified RIFLE criteria. Of the 372 patients admitted to PICU, 64 (17.2%) patients developed AKI. Of these 64 patients who had AKI, 28 (43.7%) patients reached RIFLE max of risk, 21 (32.8%) patients reached injury, and 15 (23.4%) reached failure. Mean Pediatric Risk of Mortality II score at admission was significantly higher in patients with AKI than those without P <0.001. The age ranged between one month and 14 years with the median age as 5.4 year. Thirty-five (54.7%) were males. Sepsis was the most common cause of AKI. The mortality rate in critically ill children without AKI was 58.7%, whereas increased in children with AKI to 73.4%. The mortality rate in patients who received renal replacement therapy was 71.4% and was higher (81.5%) in patients who received mechanical ventilation (95%, [confidence interval (CI)] 79.3-83.4%) and was significantly higher in patients with multi-organ system dysfunction 90.3% (95%, [CI] 88.7-92.5%). The incidence of AKI in critically ill children is high and increased their mortality rate and higher mortality seen in the younger age group, especially those below one year. High mortality rate was associated with multi-organ system dysfunction and the need for mechanical ventilation.

Antibiotics are commonly overused in adults seeking emergency department (ED) care for acute cough illness. To evaluate the effect of a point-of-care C-reactive protein (CRP) blood test on antibiotic treatment of acute cough illness in adults. A randomized controlled trial was conducted in a single urban ED in the United States. The participants were adults (age ≥ 18 years) seeking care for acute cough illness (≤ 21 days duration); 139 participants were enrolled, and 131 completed the ED visit. Between November 2005 and March 2006, study participants had attached to their medical charts a clinical algorithm with recommendations for chest X-ray study or antibiotic treatment. For CRP-tested patients, recommendations were based on the same algorithm plus the CRP level. There was no difference in antibiotic use between CRP-tested and control participants (37% [95% confidence interval (CI) 29-45%] vs. 31% [95% CI 23-39%], respectively; p = 0.46) or chest X-ray use (52% [95% CI 43-61%] vs. 48% [95% CI 39-57%], respectively; p = 0.67). Among CRP-tested participants, those with normal CRP levels received antibiotics much less frequently than those with indeterminate CRP levels (20% [95% CI 7-33%] vs. 50% [95% CI 32-68%], respectively; p = 0.01). Point-of-care CRP testing does not seem to provide any additional value beyond a point-of-care clinical decision support for reducing antibiotic use in adults with acute cough illness.

Co-infection with pathogens that cause acute febrile illness creates a diagnostic challenge as a result of overlapping clinical manifestations. Here, we describe four fatal cases of Leptospira species/dengue virus co-infection in Puerto Rico. Although all patients sought care early, antibiotic administration was delayed for most. Steroids were administered to all patients, in most cases before antibiotics. These cases show the need for clinicians evaluating patients in or recently returned from the tropics with acute febrile illness to consider both dengue and leptospirosis. Furthermore, they illustrate the need for nucleic acid- or antigen-based rapid diagnostic tests to enable timely patient diagnosis and management. In particular, antibiotic therapy should be initiated early for patients with suspected leptospirosis, and steroids should not be administered to patients with suspected dengue. PMID:25092820

With previous methods based on only age and location, there are many difficulties in identifying the etiology of acute abdominal pain in children. We sought to develop a new systematic classification of acute abdominal pain and to give some helps to physicians encountering difficulties in diagnoses. From March 2005 to May 2010, clinical data were collected retrospectively from 442 children hospitalized due to acute abdominal pain with no apparent underlying disease. According to the final diagnoses, diseases that caused acute abdominal pain were classified into nine groups. The nine groups were group I "catastrophic surgical abdomen" (7 patients, 1.6%), group II "acute appendicitis and mesenteric lymphadenitis" (56 patients, 12.7%), group III "intestinal obstruction" (57 patients, 12.9%), group IV "viral and bacterial acute gastroenteritis" (90 patients, 20.4%), group V "peptic ulcer and gastroduodenitis" (66 patients, 14.9%), group VI "hepatobiliary and pancreatic disease" (14 patients, 3.2%), group VII "febrile viral illness and extraintestinal infection" (69 patients, 15.6%), group VIII "functional gastrointestinal disorder (acute manifestation)" (20 patients, 4.5%), and group IX "unclassified acute abdominal pain" (63 patients, 14.3%). Four patients were enrolled in two disease groups each. Patients were distributed unevenly across the nine groups of acute abdominal pain. In particular, the "unclassified abdominal pain" only group was not uncommon. Considering a systemic classification for acute abdominal pain may be helpful in the diagnostic approach in children.

The central role of hypothalamic inflammation in the acute illness response and cachexia.

PubMed

Burfeind, Kevin G; Michaelis, Katherine A; Marks, Daniel L

2016-06-01

When challenged with a variety of inflammatory threats, multiple systems across the body undergo physiological responses to promote defense and survival. The constellation of fever, anorexia, and fatigue is known as the acute illness response, and represents an adaptive behavioral and physiological reaction to stimuli such as infection. On the other end of the spectrum, cachexia is a deadly and clinically challenging syndrome involving anorexia, fatigue, and muscle wasting. Both of these processes are governed by inflammatory mediators including cytokines, chemokines, and immune cells. Though the effects of cachexia can be partially explained by direct effects of disease processes on wasting tissues, a growing body of evidence shows the central nervous system (CNS) also plays an essential mechanistic role in cachexia. In the context of inflammatory stress, the hypothalamus integrates signals from peripheral systems, which it translates into neuroendocrine perturbations, altered neuronal signaling, and global metabolic derangements. Therefore, we will discuss how hypothalamic inflammation is an essential driver of both the acute illness response and cachexia, and why this organ is uniquely equipped to generate and maintain chronic inflammation. First, we will focus on the role of the hypothalamus in acute responses to dietary and infectious stimuli. Next, we will discuss the role of cytokines in driving homeostatic disequilibrium, resulting in muscle wasting, anorexia, and weight loss. Finally, we will address mechanisms and mediators of chronic hypothalamic inflammation, including endothelial cells, chemokines, and peripheral leukocytes. Copyright © 2015 Elsevier Ltd.

Background Although fever in children is often self-limiting, antibiotics are frequently prescribed for febrile illnesses. GPs may consider treating serious infections by prescribing antibiotics. Aim To examine whether alarm signs and/or symptoms for serious infections are related to antibiotic prescription in febrile children in primary care. Design and setting Observational cohort study involving five GP out-of-hours services. Method Clinical information was registered and manually recoded. Children (<16 years) with fever having a face-to-face contact with a GP were included. Children who were already using antibiotics or referred to secondary care were excluded. The relation between alarm signs and/or symptoms for serious infections and antibiotic prescription was tested using multivariate logistic regression. Results Of the 8676 included patients (median age 2.4 years), antibiotics were prescribed in 3167 contacts (36.5%). Patient characteristics and alarm signs and/or symptoms positively related to antibiotic prescription were: increasing age (odds ratio [OR] = 1.03; 95% confidence interval [95% CI] = 1.02 to 1.05), temperature measured by GP (OR = 1.72; 95% CI = 1.59 to 1.86), ill appearance (OR = 3.93; 95% CI = 2.85 to 5.42), being inconsolable (OR = 2.27; 95% CI = 1.58 to 3.22), shortness of breath (OR = 2.58; 95% CI = 1.88 to 3.56), duration of fever (OR = 1.31; 95% CI = 1.26 to 1.35). Negative associations were found for neurological signs (OR = 0.45; 95% CI = 0.27 to 0.76), signs of urinary tract infection (OR = 0.63; 95% CI = 0.49 to 0.82), and vomiting and diarrhoea (OR = 0.65; 95% CI = 0.57 to 0.74). These variables explained 19% of the antibiotic prescriptions. Conclusion Antibiotics are often prescribed for febrile children. These data suggest that treatment of a supposed serious bacterial infection is a consideration of GPs. However, the relatively low explained variation indicates that other considerations are also involved. PMID:23834880

The aim of this article was to assess the usefulness of procalcitonin (PCT) as a marker for predicting dilating (grades III-V) vesicoureteral reflux (VUR) in young children with a first febrile urinary tract infection. Children ≤2 years of age with a first febrile urinary tract infection were prospectively evaluated. Serum samples were tested for PCT at the time of admission to a tertiary hospital. All children underwent renal ultrasonography (US), Tc-dimercaptosuccinic acid renal scan, and voiding cystourethrography. The diagnostic characteristics of PCT test for acute pyelonephritis and dilating VUR were calculated. Of 272 children analyzed (168 boys and 104 girls; median age, 5 months), 169 (62.1%) had acute pyelonephritis. There was VUR demonstrated in 97 (35.7%), including 70 (25.7%) with dilating VUR. The median PCT value was significantly higher in children with VUR than in those without (P < 0.001). Using a PCT cutoff value of ≥1.0 ng/mL, the sensitivity and negative predictive value for predicting dilating VUR were 94.3% and 95.4%, respectively, for PCT, and 97.1% and 97.8%, respectively, for the combined PCT and US studies, whereas the positive and negative likelihood ratios were 2.03 and 0.107, respectively, for PCT, and 1.72 and 0.067, respectively, for the combined studies. By multivariate analysis, high PCT values and abnormalities on US were independent predictors of dilating VUR. PCT is useful for diagnosing acute pyelonephritis and predicting dilating VUR in young children with a first febrile urinary tract infection. A voiding cystourethrography is indicated only in children with high PCT values (≥1.0 ng/mL) and/or abnormalities found on a US.

Brazil will host the 2014 FIFA World Cup and the 2016 Olympic and Paralympic Games, events that are expected to attract hundreds of thousands of international travelers. Travelers to Brazil will encounter locally endemic infections as well as mass event-specific risks. We describe 1586 ill returned travelers who had visited Brazil and were seen at a GeoSentinel Clinic from July 1997 through May 2013. The most common travel-related illnesses were dermatologic conditions (40%), diarrheal syndromes (25%), and febrile systemic illness (19%). The most common specific dermatologic diagnoses were cutaneous larva migrans, myiasis, and tungiasis. Dengue and malaria, predominantly Plasmodium vivax, were the most frequently identified specific causes of fever and the most common reasons for hospitalization after travel. Dengue fever diagnoses displayed marked seasonality, although cases were seen throughout the year. Among the 28 ill returned travelers with human immunodeficiency virus (HIV) infection, 11 had newly diagnosed asymptomatic infection and 9 had acute symptomatic HIV. Our analysis primarily identified infectious diseases among travelers to Brazil. Knowledge of illness in travelers returning from Brazil can assist clinicians to advise prospective travelers and guide pretravel preparation, including itinerary-tailored advice, vaccines, and chemoprophylaxis; it can also help to focus posttravel evaluation of ill returned travelers. Travelers planning to attend mass events will encounter other risks that are not captured in our surveillance network.

Accurate diagnosis of febrile seizures in children presenting after paroxysmal episodes associated with fever, is hampered by the lack of objective postictal biomarkers. The aim of our study was to investigate whether FS are associated with increased levels of serum copeptin, a robust marker of arginine vasopressin secretion. This was a prospective emergency-setting cross-sectional study of 161 children between six months and five years of age. Of these, 83 were diagnosed with febrile seizures, 69 had a febrile infection without seizures and nine had epileptic seizures not triggered by infection. Serum copeptin and prolactin levels were measured in addition to standard clinical, neurophysiological, and laboratory assessment. NCT01884766. Circulating copeptin was significantly higher in children with febrile seizures (median [interquartile range] 18.9 pmol/L [8.5-36.6]) compared to febrile controls (5.6 pmol/L [4.1-9.4]; p < 0.001), with no differences between febrile and epileptic seizures (21.4 pmol/L [16.1-46.6]; p = 0.728). In a multivariable regression model, seizures were the major determinant of serum copeptin (beta 0.509; p < 0.001), independently of clinical and baseline laboratory indices. The area under the receiver operating curve for copeptin was 0.824 (95% CI 0.753-0.881), significantly higher compared to prolactin (0.667 [0.585-0.742]; p < 0.001). The diagnostic accuracy of copeptin increased with decreasing time elapsed since the convulsive event (at 120 min: 0.879 [0.806-0.932] and at <60 min: 0.975 [0.913-0.997]). Circulating copeptin has high diagnostic accuracy in febrile seizures and may be a useful adjunct for accurately diagnosing postictal states in the emergency setting.

To analyze the status of acute upper respiratory infection and influenza-like illness (ILI) among community residents in Jinan in 2015, and to make a understand of the patient's medical treatment behavior and influenza vaccination coverage status in 2014. Balloting method and convenient sampling method were used to launch a household survey. The residents who had been in Jinan for more than 3 months were selected, to investigate the residents' attack ratio of acute upper respiratory and influenza-like from Jan. 8 to Feb. 7, 2015. Totally, 1 300 persons from 410 families were involved in this survey which recovered 1 241 valid questionnaires with the efficiency of 95.5%. Based on the national age-urban demographic statistics in 2010, the attack rates of acute respiratory infections, influenza-like illness were estimated by the direct standardization method, and the influenza vaccination rates were also calculated in this study. χ(2)-test method was used to compare the different status of incidence and vaccination among residents with different features. The attack rate of acute upper respiratory infection and influenza-like illness in Jinan from January 8, 2015 to February 7, 2015 were 30.2% (375 cases), and 6.1% (76 cases), respectively, with a standardized rate of 29.1% and 5.4%. 5.3% (66 cases) of the residents have vaccinated with the influenza vaccine inoculation, with an adjusted rate of 3.8%. The attack rate difference of acute upper respiratory tract infections was statistically significant between each age group (χ(2)=17.121, P= 0.002). The 0-4 age group had a highest attack rate (45.4%) of acute respiratory infection, while the 15-24 age group got the lowest (26.5%). 38.9% (146 cases) of patients went for a treatment in hospital. Among them, 37.7% (55 cases) of them selected the county level hospitals for treatment, 37.7% (55 cases) selected the community level hospitals, and 24.6% (36 cases) selected the individual clinic.

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.

To determine the incidence of dengue infection, we established active surveillance of febrile episodes in a cohort of schoolchildren from three schools in Medellin, Colombia. We followed a cohort of 2,379 schoolchildren in 2010 and followed 1,840 of these children the following year. During the follow-up time, 264 schoolchildren displayed 297 febrile episodes; of these, 23 episodes (7.7%) were caused by acute dengue infection. All four dengue serotypes were found, and all of the cases were mild. The most common symptoms in the dengue cases compared with those in other febrile illness were asthenia (96% versus 87%), anorexia (78% versus 57%), rhinorrhea (65.2% versus 58%), abdominal pain (56.5% versus 47.8%), arthralgia (43% versus 33%), and positive tourniquet test (13% versus 3%). This difference was not statistically significant. Pulse was elevated, and systolic arterial pressure was lower in dengue cases compared with other febrile illness (P < 0.05). Mosquito indexes were determined in 8 children's houses and in the schools. Aedes aegypti adults were found in both households and in schools, whereas Aedes aegypti larvae were found only in schools. These results showed an elevated dengue frequency in children, with symptoms similar to those of other febrile illness and transmission risk in households and schools. PMID:23304167

Background. Influenza causes significant morbidity and mortality, with considerable economic costs, including lost work productivity. Influenza vaccines may reduce the economic burden through primary prevention of influenza and reduction in illness severity. Methods. We examined illness severity and work productivity loss among working adults with medically attended acute respiratory illnesses and compared outcomes for subjects with and without laboratory-confirmed influenza and by influenza vaccination status among subjects with influenza during the 2012–2013 influenza season. Results. Illnesses laboratory-confirmed as influenza (ie, cases) were subjectively assessed as more severe than illnesses not caused by influenza (ie, noncases) based on multiple measures, including current health status at study enrollment (≤7 days from illness onset) and current activity and sleep quality status relative to usual. Influenza cases reported missing 45% more work hours (20.5 vs 15.0; P < .001) than noncases and subjectively assessed their work productivity as impeded to a greater degree (6.0 vs 5.4; P < .001). Current health status and current activity relative to usual were subjectively assessed as modestly but significantly better for vaccinated cases compared with unvaccinated cases; however, no significant modifications of sleep quality, missed work hours, or work productivity loss were noted for vaccinated subjects. Conclusions. Influenza illnesses were more severe and resulted in more missed work hours and productivity loss than illnesses not confirmed as influenza. Modest reductions in illness severity for vaccinated cases were observed. These findings highlight the burden of influenza illnesses and illustrate the importance of laboratory confirmation of influenza outcomes in evaluations of vaccine effectiveness. PMID:26565004

The eight-item Brief Illness Perception Questionnaire is used as a screening instrument in physical therapy to assess mental defeat in patients with acute low back pain, besides patient perception might determine the course and risk for chronic low back pain. However, the psychometric properties of the Brief Illness Perception Questionnaire in common musculoskeletal disorders like acute low back pain have not been adequately studied. Patients' perceptions vary across different populations and affect coping styles. Thus, our aim was to determine the internal consistency, test-retest reliability and validity of the Dutch language version of the Brief Illness Perception Questionnaire in acute non-specific low back pain patients in primary care physical therapy. A non-experimental cross-sectional study with two measurements was performed. Eighty-four acute low back pain patients, in multidisciplinary health care center in Dutch primary care with a sample mean (SD) age of 42 (12) years, participated in the study. Internal consistency (Cronbach's α) and test-retest procedures (Intraclass Correlation Coefficients and limits of agreement) were evaluated at a one-week interval. The concurrent validity of the Brief Illness Perception Questionnaire was examined by using the Mental Health Component of the Short Form 36 Health Survey. The Cronbach's α for internal consistency was 0.73 (95% CI, 0.67 - 0.83); and the Intraclass Correlation Coefficient test-retest reliability was acceptable: 0.72 (95% CI, 0.53 - 0.82), however, the limits of agreement were large. The Intraclass Correlation Coefficient measuring concurrent validity 0.65 (95% CI, 0.46 - 0.80). The Dutch version of the Brief Illness Perception Questionnaire is an appropriate instrument for measuring patients' perceptions in acute low back pain patients, showing acceptable internal consistency and reliability. Concurrent validity is adequate, however, the instrument may be unsuitable for detecting changes in low

Clinical evidence suggests that febrile status epilepticus (SE) in children can lead to acute hippocampal injury and subsequent temporal lobe epilepsy. The contribution of febrile SE to the mechanisms underlying temporal lobe epilepsy are however poorly understood. A rat model of temporal lobe epilepsy following hyperthermic SE was previously established in our laboratory, wherein a focal cortical lesion induced at postnatal day 1 (P1), followed by a hyperthermic SE (more than 30 min) at P10, leads to hippocampal atrophy at P22 (dual pathology model) and spontaneous recurrent seizures (SRS) with mild visuospatial memory deficits in adult rats. The goal of this study was to identify the long term electrophysiological, anatomical and molecular changes in this model. Following hyperthermic SE, all cortically lesioned pups developed progressive SRS as adults, characterized by the onset of highly rhythmic activity in the hippocampus. A reduction of hippocampal volume on the side of the lesion preceded the SRS and was associated with a loss of hippocampal neurons, a marked decrease in pyramidal cell spine density, an increase in the hippocampal levels of NMDA receptor NR2A subunit, but no significant change in GABA receptors. These findings suggest that febrile SE in the abnormal brain leads to hippocampal injury that is followed by progressive network reorganization and molecular changes that contribute to the epileptogenesis as well as the observed memory deficits.

The disease pyramid of under-ascertainment for surveillance of acute gastrointestinal illness (AGI) in New Zealand has been estimated using 2005-2007 data on notifiable diseases, a community telephone survey, and a survey of diagnostic laboratories. For each notified case of AGI there were an estimated 222 cases in the community, about 49 of which visited a general practitioner. Faecal samples were requested from about 15 of these cases, and 13 samples were provided. Of the faecal samples, pathogens were detected in about three cases. These ratios are similar to those reported in other developed countries, and provide baseline measurements of the AGI burden in the New Zealand community.

Computerized morbidity registration networks might serve as early warning systems in a time where natural epidemics such as the H1N1 flu can easily spread from one region to another. In this contribution we examine whether general practice based broad-spectrum computerized morbidity registration networks have the potential to act as a valid surveillance instrument of frequently occurring diseases. We compare general practice based computerized data assessing the frequency of influenza-like illness (ILI) and acute respiratory infections (ARI) with data from a well established case-specific sentinel network, the European Influenza Surveillance Scheme (EISS). The overall frequency and trends of weekly ILI and ARI data are compared using both networks. Detection of influenza-like illness and acute respiratory illness occurs equally fast in EISS and the computerized network. The overall frequency data for ARI are the same for both networks, the overall trends are similar, but the increases and decreases in frequency do not occur in exactly the same weeks. For ILI, the overall rate was slightly higher for the computerized network population, especially before the increase of ILI, the overall trend was almost identical and the increases and decreases occur in the same weeks for both networks. Computerized morbidity registration networks are a valid tool for monitoring frequent occurring respiratory diseases and the detection of sudden outbreaks.

We examined the ability of a procalcitonin (PCT) protocol to detect vesicoureteral reflux (VUR) and renal scarring (RS), evaluated procedural costs and radiation burden, and compared four representative guidelines for children with their first febrile urinary tract infection (UTI). Children aged ≤2 years with their first febrile UTI who underwent renal ultrasonography (US), acute and late technetium-99m ((99m)Tc)-dimercaptosuccinic acid scan, and voiding cystourethrography were prospectively studied. The representative guidelines applied in a retrospective simulation included the American Academy of Pediatrics (AAP), National Institute of Clinical Excellence, top-down approach (TDA), and Italian Society of Pediatric Nephrology (ISPN). These were compared in terms of ability to detect abnormalities, procedural costs and radiation. Of 278 children analyzed, 172 (61.9%) had acute pyelonephritis. There was VUR in 101 (36.3%) children, including 73 (26.3%) with grades III-V VUR. RS was identified in 75 (27.0%) children. To detect VUR, TDA and PCT had the highest sensitivity for grades I-V VUR (80.2%) and III-V VUR (94.5%), respectively, whereas AAP had the highest specificity for I-V VUR (77.4%) and III-V VUR (78.0%), respectively. TDA and PCT had the highest sensitivity (100%) for detecting RS. The highest cost and radiation dose was associated with TDA, whereas AAP had the least expenditure and radiation exposure. By multivariate analysis, PCT and VUR, especially grades III-V, were independent predictors of RS. There is no perfect guideline for first febrile UTI children. The PCT protocol has good ability for detecting high-grade VUR and RS. If based on available imaging modalities and reducing cost and radiation burden, clinical suggestions in the AAP guidelines represent a considerable protocol.

Introduction Translational systems biology approaches can be distinguished from mainstream systems biology in that their goal is to drive novel therapies and streamline clinical trials in critical illness. One systems biology approach, dynamic mathematical modeling (DMM), is increasingly used in dealing with the complexity of the inflammatory response and organ dysfunction. The use of DMM often requires a broadening of research methods and a multidisciplinary team approach that includes bioscientists, mathematicians, engineers, and computer scientists. However, the development of these groups must overcome domain-specific barriers to communication and understanding. Methods We present four case studies of successful translational, interdisciplinary systems biology efforts, which differ by organizational level from an individual to an entire research community. Results Case 1 is a single investigator involved in DMM of the acute inflammatory response at Cook County Hospital, in which extensive translational progress was made using agent-based models of inflammation and organ damage. Case 2 is a community-level effort from the University of Witten-Herdecke in Cologne, whose efforts have led to the formation of the Society for Complexity in Acute Illness. Case 3 is an institution-based group, the Biosystems Group at the University of California, San Francisco, whose work has included a focus on a common lexicon for DMM. Case 4 is an institution-based, trans-disciplinary research group (the Center for Inflammation and Regenerative Modeling at the University of Pittsburgh, whose modeling work has led to internal education efforts, grant support, and commercialization. Conclusion A transdisciplinary approach, which involves team interaction in an iterative fashion to address ambiguity and is supported by educational initiatives, is likely to be necessary for DMM in acute illness. Community-wide organizations such as the Society of Complexity in Acute Illness (SCAI) must

Epilepsy, febrile seizures, and attention-deficit/hyperactivity disorder (ADHD) are disorders of the central nervous system and share common risk factors. Our goal was to examine the association in a nationwide cohort study with prospective follow-up and adjustment for selected confounders. We hypothesized that epilepsy and febrile seizures were associated with subsequent ADHD. A population-based cohort of all children born in Denmark from 1990 through 2007 was followed up until 2012. Incidence rate ratios (IRRs) and 95% confidence intervals (95% CIs) for ADHD were estimated by using Cox regression analysis, comparing children with epilepsy and febrile seizure with those without these disorders, adjusted for socioeconomic and perinatal risk factors, as well as family history of neurologic and psychiatric disorders. A total of 906 379 individuals were followed up for 22 years (∼10 million person-years of observation); 21 079 individuals developed ADHD. Children with epilepsy had a fully adjusted IRR of ADHD of 2.72 (95% CI, 2.53-2.91) compared with children without epilepsy. Similarly, in children with febrile seizure, the fully adjusted IRR of ADHD was 1.28 (95% CI, 1.20-1.35). In individuals with both epilepsy and febrile seizure, the fully adjusted IRR of ADHD was 3.22 (95% CI, 2.72-3.83). Our findings indicate a strong association between epilepsy in childhood and, to a lesser extent, febrile seizure and subsequent development of ADHD, even after adjusting for socioeconomic and perinatal risk factors, and family history of epilepsy, febrile seizures, or psychiatric disorders.

We conducted a retrospective study to compare the outcome of intravenous midazolam infusion without electroencephalography or targeted temperature management and barbiturate coma therapy with electroencephalography and targeted temperature management for treating convulsive refractory febrile status epilepticus. Of 49 consecutive convulsive refractory febrile status epilepticus patients admitted to the pediatric intensive care unit of our hospital, 29 were excluded because they received other treatments or because of various underlying illnesses. Thus, eight patients were treated with midazolam and 10 with barbiturate coma therapy using thiamylal. Midazolam-treated patients were intubated only when necessary, whereas barbiturate coma therapy patients were routinely intubated. Continuous electroencephalography monitoring was utilized only for the barbiturate coma group. The titration goal for anesthesia was clinical termination of status epilepticus in the midazolam group and suppression or burst-suppression patterns on electroencephalography in the barbiturate coma group. Normothermia was maintained using blankets and neuromuscular blockade in the barbiturate coma group and using antipyretics in the midazolam group. Prognoses were measured at 1 month after onset; children were classified into poor and good outcome groups. Good outcome was achieved in all the barbiturate coma group patients and 50% of the midazolam group patients (P = 0.02, Fisher's exact test). Although the sample size was small and our study could not determine which protocol element is essential for the neurological outcome, the findings suggest that clinical seizure control using midazolam without continuous electroencephalography monitoring or targeted temperature management is insufficient in preventing neurological damage in children with convulsive refractory febrile status epilepticus.

Ngari, Bunyamwera, Ilesha, and Germiston viruses are among the mosquito-borne human pathogens in the Orthobunyavirus genus, family Bunyaviridae, associated with febrile illness. Although the four orthobunyaviruses have been isolated from mosquito and/or tick vectors sampled from different geographic regions in Kenya, little is known of human exposure in such areas. We conducted a serologic investigation to determine whether orthobunyaviruses commonly infect humans in Kenya. Orthobunyavirus-specific antibodies were detected by plaque reduction neutralization tests in 89 (25.8%) of 345 persons tested. Multivariable analysis revealed age and residence in northeastern Kenya as risk factors. Implementation of acute febrile illness surveillance in northeastern Kenya will help to detect such infections.

India, home to almost 1.5 billion people, is in need of a country-specific, evidence-based, consensus approach for the emergency department (ED) evaluation and management of the febrile child. We held two consensus meetings, performed an exhaustive literature review, and held ongoing web-based discussions to arrive at a formal consensus on the proposed evaluation and management algorithm. The first meeting was held in Delhi in October 2015, under the auspices of Pediatric Emergency Medicine (PEM) Section of Academic College of Emergency Experts in India (ACEE-INDIA); and the second meeting was conducted at Pune during Emergency Medical Pediatrics and Recent Trends (EMPART 2016) in March 2016. The second meeting was followed with futher e-mail-based discussions to arrive at a formal consensus on the proposed algorithm. To develop an algorithmic approach for the evaluation and management of the febrile child that can be easily applied in the context of emergency care and modified based on local epidemiology and practice standards. We created an algorithm that can assist the clinician in the evaluation and management of the febrile child presenting to the ED, contextualized to health care in India. This guideline includes the following key components: triage and the timely assessment; evaluation; and patient disposition from the ED. We urge the development and creation of a robust data repository of minimal standard data elements. This would provide a systematic measurement of the care processes and patient outcomes, and a better understanding of various etiologies of febrile illnesses in India; both of which can be used to further modify the proposed approach and algorithm.

Background Leptospirosis is an emerging but neglected public health challenge in the Asia/Pacific Region with an annual incidence estimated at 10–100 per 100,000 population. No accurate data, however, are available for at-risk rural Cambodian communities. Method We conducted anonymous, unlinked testing for IgM antibodies to Leptospira spp. on paired sera of Cambodian patients <20 years of age between 2007–2009 collected through active, community-based surveillance for febrile illnesses in a convenience sample of 27 rural and semi-rural villages in four districts of Kampong Cham province, Cambodia. Leptospirosis testing was done on paired serological samples negative for Dengue, Japanese encephalitis and Chikungunya viruses after random selection. Convalescent samples found positive while initial samples were negative were considered as proof of acute infection. We then applied a mathematical model to estimate the risk of fever caused by leptospirosis, dengue or other causes in rural Cambodia. Results A total of 630 samples are coming from a randomly selected subset of 2358 samples. IgM positive were found on the convalescent serum sample, among which 100 (15.8%) samples were IgM negative on an earlier sample. Seventeen of these 100 seroconversions were confirmed using a Microagglutination Test. We estimated the probability of having a fever due to leptospirosis at 1. 03% (95% Credible Interval CI: 0. 95%–1. 22%) per semester. In comparison, this probability was 2. 61% (95% CI: 2. 55%, 2. 83%) for dengue and 17. 65% (95% CI: 17. 49%, 18. 08%) for other causes. Conclusion Our data from febrile cases aged below 20 years suggest that the burden of leptospirosis is high in rural Cambodian communities. This is especially true during the rainy season, even in the absence of identified epidemics. PMID:27043016

Thyroid hormone elevations during acute psychiatric illness: relationship to severity and distinction from hyperthyroidism.

Acute psychiatric illness may be accompanied by transient hyperthyroxinemia. The mechanism of this phenomenon was examined by determining the role of thyrotropin (TSH) in the genesis of this state. Serial measurements of TSH, thyroxine (T4), free T4 index (FT4I), triiodothyronine (T3), and free T3 index (FT3I) were performed in 45 acutely hospitalized patients with major psychiatric disorders. Twenty-two (49%) patients exhibited significant elevations (greater than or equal to 2 SD above mean value of controls) of one or more thyroid hormone (or index) levels. Among depressed patients with elevated FT4I, TSH was higher (p less than .05) on the day of the peak FT4I than on the day of the FT4I nadir. There were significant positive correlations between psychiatric symptom severity and levels of FT4I among both depressed (p less than .01) and schizophrenic (p less than .025) patients. These data show that elevations of T4, FT4I, T3, and FT3I are common among psychiatric inpatients, especially early in their hospitalization, and that levels of thyroid hormones are correlated with severity of psychiatric symptomatology. TSH is higher early in the acute phase of illness and is not suppressed in the face of elevated thyroid hormone levels, a finding that distinguishes this phenomenon from ordinary hyperthyroidism. Elevations of peripheral thyroid hormone levels, particularly among depressed patients, may result from a centrally-mediated hypersecretion of TSH.

We performed a descriptive analysis of acute and potentially life-threatening tropical diseases among 82,825 ill western travelers reported to GeoSentinel from June of 1996 to August of 2011. We identified 3,655 patients (4.4%) with a total of 3,666 diagnoses representing 13 diseases, including falciparum malaria (76.9%), enteric fever (18.1%), and leptospirosis (2.4%). Ninety-one percent of the patients had fever; the median time from travel to presentation was 16 days. Thirteen (0.4%) patients died: 10 with falciparum malaria, 2 with melioidosis, and 1 with severe dengue. Falciparum malaria was mainly acquired in West Africa, and enteric fever was largely contracted on the Indian subcontinent; leptospirosis, scrub typhus, and murine typhus were principally acquired in Southeast Asia. Western physicians seeing febrile and recently returned travelers from the tropics need to consider a wide profile of potentially life-threatening tropical illnesses, with a specific focus on the most likely diseases described in our large case series.

A 38 year old man with history of obstructive sleep apnea and polycythaemia presented with hypercapnic respiratory failure that required intubation. He developed fever with infiltrates on chest radiography that required empiric antifungal therapy with fluconazole along with broad spectrum antibiotics. He developed acute adrenal insufficiency that recovered after fluconazole was stopped. It is believed that this complication of adrenal suppression attributable to fluconazole is underrecognised and it may be prudent to monitor all critically ill patients who are given fluconazole for this complication.

A febrile seizure (FS) is the most common convulsive disorder in children. Activation of cytokine network is involved in FS pathogenesis. Adiponectin, leptin and IL-6 are the major adipocytokines secreted by fat cells. To date, only a few studies concerned the association of adipocytokines with febrile seizures. In this study, we tried to investigate serum and CSF levels of adiponectin, leptin, and interleukin-6 (IL-6); as adipocytokines, for the first time in Egyptian children with febrile seizures. This was a prospective cross-sectional study included one hundred patients with febrile seizure, and matched with age, gender, 100 children with febrile illness without seizures (febrile control, FC) and 100 healthy control group (HC). Serum and cerebrospinal fluid (CSF) levels of adiponectin, leptin, and (IL-6) were measured by enzyme-linked immunosorbent assay (ELISA) method. Serum adiponectin was significantly higher in children with FS (16.8 ± 3.7 ug/ml) and the FC group (18.3 ± 4.3 ug/ml) compared to the HC group (9.5 ± 2.2 ug/ml); P < 0.05, respectively. Serum leptin was significantly lower in children with FS (0.9 ± 0.3 ng/ml) compared to both the FC group (4.7 ± 1.2 ng/ml) and the HC group (1.8 ± 0.4 ng/ml); P < 0.01, respectively. Children with FS had significantly higher serum IL-6 levels (43.7 ± 11.7 ng/ml) than the FC group (21.9 ± 4.5 ng/ml) and the HC group (6.5 ± 1.8 ng/ml); P < 0.01, respectively. Patients with simple febrile seizures (SFS) had serum and CSF adiponectin levels similar to those with complex febrile seizures (CFS); (P > 0.05). Serum and CSF leptin levels were significantly lower in patients with CFS compared to the SFS group (P < 0.05). Serum and CSF IL-6 levels were significantly higher in patients with CFS compared to the SFS group (P < 0.01). On multivariate logistic regression analysis, the high serum IL-6 levels was the most significant risk factor associated with

Reducing Emergency Department Visits for Acute Gastrointestinal Illnesses in North Carolina (USA) by Extending Community Water Service

DeFelice, Nicholas B.; Johnston, Jill E.; Gibson, Jacqueline MacDonald

Background: Previous analyses have suggested that unregulated private drinking water wells carry a higher risk of exposure to microbial contamination than regulated community water systems. In North Carolina, ~35% of the state’s population relies on private wells, but the health impact associated with widespread reliance on such unregulated drinking water sources is unknown. Objectives: We estimated the total number of emergency department visits for acute gastrointestinal illness (AGI) attributable to microbial contamination in private wells in North Carolina per year, the costs of those visits, and the potential health benefits of extending regulated water service to households currently relying on private wells for their drinking water. Methods: We developed a population intervention model using 2007–2013 data from all 122 North Carolina emergency departments along with microbial contamination data for all 2,120 community water systems and for 16,138 private well water samples collected since 2008. Results: An estimated 29,400 (95% CI: 26,600, 32,200) emergency department visits per year for acute gastrointestinal illness were attributable to microbial contamination in drinking water, constituting approximately 7.3% (95% CI: 6.6, 7.9%) of all AGI-related visits. Of these attributable cases, 99% (29,200; 95% CI: 26,500, 31,900) were associated with private well contamination. The estimated statewide annual cost of emergency department visits attributable to microbiological contamination of drinking water is 40.2 million USD (95% CI: 2.58 million USD, 193 million USD), of which 39.9 million USD (95% CI: 2.56 million USD, 192 million USD) is estimated to arise from private well contamination. An estimated 2,920 (95% CI: 2,650, 3,190) annual emergency department visits could be prevented by extending community water service to 10% of the population currently relying on private wells. Conclusions: This research provides new evidence that extending regulated

Predictive factors for poor prognosis febrile neutropenia.

Most patients with chemotherapy-induced febrile neutropenia recover rapidly without serious complications. However, it still remains a life-threatening treatment-related toxicity, and is associated with dose reductions and delays of chemotherapeutic agents that may compromise treatment outcomes. Recent developments of risk stratification enabled early discharge with oral antibiotics for low-risk patients. However, even in low-risk patients, medical complications including bacteremia could happen. The authors reviewed recent literature to provide an update on research regarding predictive factors for poor prognosis in patients with febrile neutropenia. Various prognostic factors have been suggested with controversies. Hematological parameters, prophylactic measurements and patient-specific risk factors showed inconsistent results. MASCC risk-index score, which was originally developed to identify low-risk patients, in turn showed that the lower the MASCC score, the poorer the prognosis of febrile neutropenia, with very low levels (<15), the rate of complications was high. Patients with severe sepsis and septic shock commonly had procalcitonin concentration above 2.0 ng/ml, and this level should be considered at high risk of poor prognosis. Lower MASCC score and higher procalcitonin concentration can predict poor outcomes in febrile neutropenia. More research is required with regard to the other factors showing controversies.

To examine the contribution of the Healthcare Assistant (HCA) as the recogniser, responder and recorder of acutely ill patients within the general ward setting. Concerns have been highlighted regarding the recognition and management of the acutely ill patient within the general ward setting. The contribution of the HCA role to this process has been given limited attention. A postal survey of HCAs was piloted and conducted within two district general hospitals. Open and closed questions were used. Results suggest that on a regular basis HCAs are caring for acutely ill patients. Contextual issues and inaccuracies in some aspects of patient assessment were highlighted. It would appear normal communication channels and hierarchies were bypassed when patients' safety was of concern. Educational needs were identified including scenario-based learning and the importance of ensuring mandatory training is current. HCAs play a significant role in the detection and monitoring of acutely ill patients. Acknowledgement is needed of the contextual factors in the general ward setting which may influence the quality of this process. The educational needs identified by this study can assist managers to improve clinical supervision and educational input in order to improve the quality of care for acutely ill patients.

Dengue is an acute febrile illness caused by any of four mosquito-transmitted dengue virus (DENV) types. Dengue is endemic in Jamaica, where an epidemic occurred in 2012. An investigation was conducted by multiple agencies for 66 missionaries traveling from nine US states to Jamaica after 1 missionary from the group was confirmed to have dengue. Travelers were offered diagnostic testing, and a survey was administered to assess knowledge, behaviors, and illness. Of 42 survey respondents, 9 (21%) respondents reported an acute febrile illness during or after travel to Jamaica. Of 15 travelers that provided serum specimens, 4 (27%) travelers had detectable anti-DENV immunoglobulin M antibody, and 1 traveler also had DENV-1 detected by reverse transcriptase polymerase chain reaction. Recent or past infection with a DENV was evident in 93% (13 of 14) missionaries with available sera. No behavioral or demographic factors were significantly associated with DENV infection. This investigation shows that even trips of short duration to endemic areas present a risk of acquiring dengue. © The American Society of Tropical Medicine and Hygiene.

Post-intensive care syndrome (PICS), which encompasses profound psychological morbidity, affects many survivors of critical illness. We hypothesize that acute psychological stress during the intensive care unit (ICU) confinement likely contributes to PICS. In order to develop strategies that mitigate PICS associated psychological morbidity, it is paramount to first characterize acute ICU psychological stress and begin to understand its causative and protective factors. A structured interview study was administered to adult critical illness survivors who received ≥48h of mechanical ventilation in medical and surgical ICUs of a tertiary care center, and their families. Fifty patients and 44 family members were interviewed following ICU discharge. Patients reported a high level of psychological distress. The families' perception of patient's stress level correlated with the patient's self-estimated stress level both in daily life (rho=0.59; p<0.0001) and in ICU (rho=0.45; p=0.002). 70% of patients experienced fear of death, 38% had additional other fears, 48% had hallucinations. Concerns included inability to communicate (34%), environmental factors (30%), procedures and restraints (24%), and being intubated (12%). Emotional support of family/friend/staff/clergy (86%), and physical therapy/walking (14%) were perceived to be important mitigating factors. Clinicians' actions that were perceived to be very constructive included reassurance (54%), explanations (32%) and physical touch (8%). Fear, hallucinations, and the inability to communicate, are identified as central contributors to psychological stress during an ICU stay; the presence of family, and physician's attention are categorized as important mitigating factors. Patients and families identified several practical recommendations which may help assuage the psychological burden of the ICU stay. Copyright © 2017 Elsevier Inc. All rights reserved.

An outbreak of acute febrile illness occurred in the Republic of Korea Air Force boot camp from May to July 2011. An epidemiological investigation of the causative agent, which was of a highly infective nature, was conducted. Throat swabs were carried out and a multiplex reverse transcriptase-polymerase chain reaction (RT-PCR) assay was performed to identify possible causative factors. The mean age of patients who had febrile illness during the study period was 20.24 years. The multiplex RT-PCR assay identified respiratory syncytial virus (RSV) as the causative agent. The main symptoms were sore throat (76.0%), sputum (72.8%), cough (72.1%), tonsillar hypertrophy (67.9%), and rhinorrhea (55.9%). The mean temperature was 38.75°C and the attack rate among the recruits was 15.7% (588 out of 3750 recruits), while the mean duration of fever was 2.3 days. The prognosis was generally favorable with supportive care but recurrent fever occurred in 10.1% of the patients within a month. This is the first epidemiological study of an RSV outbreak that developed in a healthy young adult group. In the event of an outbreak of an acute febrile illness of a highly infective nature in facilities used by a young adult group, RSV should be considered among the possible causative agents.

Differentiating dengue patients from other acute febrile illness patients is a great challenge among physicians. Several dengue diagnosis methods are recommended by WHO. The application of specific laboratory tests is still limited due to high cost, lack of equipment, and uncertain validity. Therefore, clinical diagnosis remains a common practice especially in resource limited settings. Bayesian networks have been shown to be a useful tool for diagnostic decision support. This study aimed to construct Bayesian network models using basic demographic, clinical, and laboratory profiles of acute febrile illness patients to diagnose dengue. Data of 397 acute undifferentiated febrile illness patients who visited the fever clinic of the Bangkok Hospital for Tropical Diseases, Thailand, were used for model construction and validation. The two best final models were selected: one with and one without NS1 rapid test result. The diagnostic accuracy of the models was compared with that of physicians on the same set of patients. The Bayesian network models provided good diagnostic accuracy of dengue infection, with ROC AUC of 0.80 and 0.75 for models with and without NS1 rapid test result, respectively. The models had approximately 80% specificity and 70% sensitivity, similar to the diagnostic accuracy of the hospital's fellows in infectious disease. Including information on NS1 rapid test improved the specificity, but reduced the sensitivity, both in model and physician diagnoses. The Bayesian network model developed in this study could be useful to assist physicians in diagnosing dengue, particularly in regions where experienced physicians and laboratory confirmation tests are limited.

Oral versus intravenous antibiotics in treatment of paediatric febrile neutropenia.

2013-03-01

The purpose of this study is to determine whether, in low-risk febrile neutropenic paediatric populations, oral antibiotics are as effective as intravenous antibiotics in obtaining resolution of the febrile neutropenic episode. A comprehensive literature search of MEDLINE, EMBASE and CENTRAL identified prospective, randomised controlled trials comparing oral antibiotics with intravenous antibiotics in the treatment of febrile neutropenic episodes in low-risk paediatric oncology patients. Outcomes assessed were mortality, rate of treatment failure, length of the febrile neutropenic episode and adverse events. The random effects model was used to calculate risk ratios (RRs) for dichotomous data and mean difference with standard deviation for continuous data. Seven trials were included in the overall analysis, which included 934 episodes of febrile neutropenia in 676 patients aged between 9 months and 20 years. The overall treatment failure rates were not significantly different between oral and intravenous antibiotics (RR: 1.02, 95% confidence interval 0.78-1.32, P= 0.91). In carefully selected low-risk febrile neutropenic children, empiric treatment with oral antibiotics is a safe and effective alternative to intravenous antibiotics as they lower the cost of treatment as well as psychosocial burden on these children and their families. © 2011 The Authors.

Previous research has identified clinical predictors for urinary tract infection (UTI) to guide urine screening in febrile children <24 months of age. These studies have been limited to single centers, and few have focused on young infants who may be most at risk for complications if a UTI is missed. The objective of this study was to identify clinical and demographic factors associated with UTI in febrile infants who are < or =60 days of age using a prospective multicenter cohort. We conducted a multicenter, prospective, cross-sectional study during consecutive bronchiolitis seasons. All febrile (> or =38 degrees C) infants who were < or =60 days of age and seen at any of 8 pediatric emergency departments from October through March 1999-2001 were eligible. Clinical appearance was evaluated using the Yale Observation Scale. UTI was defined as growth of a known bacterial pathogen from a catheterized specimen at a level of (1) > or =50000 cfu/mL or (2) > or =10000 cfu/mL in association with a positive dipstick test or urinalysis. We used bivariate tests and multiple logistic regression to identify demographic and clinical factors that were associated with the likelihood of UTI. A total of 1025 (67%) of 1513 eligible patients were enrolled; 9.0% of enrolled infants received a diagnosis of UTI. Uncircumcised male infants had a higher rate of UTI (21.3%) compared with female (5.0%) and circumcised male (2.3%) infants. Infants with maximum recorded temperature of > or =39 degrees C had a higher rate of UTI (16.3%) than other infants (7.2%). After multivariable adjustment, UTI was associated with being uncircumcised (odds ratio: 10.4; bias-corrected 95% confidence interval: 4.7-31.4) and maximum temperature (odds ratio: 2.4 per degrees C; 95% confidence interval: 1.5-3.6).

Objective. Mannose-binding lectin (MBL) is important in the innate immune response. MBL2 gene polymorphisms affect MBL expression, and genotypes yielding low MBL levels have been associated with an elevated risk for infections in hematological cancer patients undergoing chemotherapy. However, these reported associations are inconsistent, and data on patients with solid tumors are lacking. Here, we investigated the effects of MBL2 genotypes on irinotecan-induced febrile neutropenia in patients with solid tumors. Patients and Methods. Irinotecan-treated patients were genotyped for the MBL2 gene. Two promoter (−550 H/L and −221 X/Y) and three exon polymorphisms (52 A/D, 54 A/B, and 57 A/C) were determined, together with known risk factors for irinotecan-induced toxicity. Neutropenia and febrile neutropenia were recorded during the first course. Results. Of the 133 patients, 28% experienced severe neutropenia and 10% experienced febrile neutropenia. No associations were found between exon polymorphisms and febrile neutropenia. However, patients with the H/H promoter genotype, associated with high MBL levels, experienced significantly more febrile neutropenia than patients with the H/L and L/L genotypes (20% versus 13% versus 5%). Moreover, patients with the HYA haplotype encountered significantly more febrile neutropenia than patients without this high MBL-producing haplotype (16% versus 4%). In the subgroup with wild-type exon polymorphisms (A/A), patients with the high MBL promoter phenotype had the highest incidence of febrile neutropenia, regardless of known risk factors. Conclusion. Patients with high MBL2 promoter genotypes and haplotypes seem more at risk for developing febrile neutropenia. If confirmed, these preliminary findings may contribute to more individualized approaches of irinotecan treatment. PMID:20930093

Aim Percutaneous Endoscopic Gastrostomy (PEG) tube is an important method of enteral feeding for patients who require temporary or long-term artificial nutritional support to prevent or correct disease-related malnutrition. However, there is paucity of data on the utility of short-term PEG tube placements in acute illnesses in cognitively intact elderly. Methods We present a series of seven, cognitively intact patients (age range = 72 to 93 years), who had PEG tubes placed for short periods. These patients were diagnosed with “failure to thrive” and were managed by placing a PEG tube temporarily for nutritional management. None of these patients had terminal illness or hospice eligibility and all of our patients were community dwellers. Results All our elderly patients experienced good outcomes in terms of their functional status and nutritional support. Conclusions Our series clearly supports the notion that short-term PEG tube placement in cognitively-intact elderly patients could be a successful strategy to support them during an episode of acute illness and to improve their nutritional deficits and survival.

To understand geographic variation in travel-related illness acquired in distinct African regions, we used the GeoSentinel Surveillance Network database to analyze records for 16,893 ill travelers returning from Africa over a 14-year period. Travelers to northern Africa most commonly reported gastrointestinal illnesses and dog bites. Febrile illnesses were more common in travelers returning from sub-Saharan countries. Eleven travelers died, 9 of malaria; these deaths occurred mainly among male business travelers to sub-Saharan Africa. The profile of illness varied substantially by region: malaria predominated in travelers returning from Central and Western Africa; schistosomiasis, strongyloidiasis, and dengue from Eastern and Western Africa; and loaisis from Central Africa. There were few reports of vaccine-preventable infections, HIV infection, and tuberculosis. Geographic profiling of illness acquired during travel to Africa guides targeted pretravel advice, expedites diagnosis in ill returning travelers, and may influence destination choices in tourism.

[Febrile neutropenia in cancer patients: management in the emergency room].

PubMed

Rivera-Salgado, Daniel; Valverde-Muñoz, Kathia; Ávila-Agüero, María L

Febrile neutropenia is a life-threatening condition that requires immediate attention, especially in patients with chemotherapy-related neutropenia. Patients with febrile neutropenia have a much greater risk of developing bacterial disease, and fever may be the only indicator of severe bacterial infection. Adequate management of febrile neutropenia emphasizes early recognition of patients, risk stratification, and antibiotic therapy administration during the first 60 minutes of admission to an emergency room. Not all children with febrile neutropenia carry the same risk of morbidity and mortality, so in recent years, efforts have been made to distinguish between high-risk patients where more aggressive hospital management is required. In children classified as low-risk, outpatient management may be considered initially or after 72 hours, whilst high-risk patients should be hospitalized and managed with parenteral antibiotics.

Advances in management of low-risk febrile neutropenia.

To describe and discuss the most recent advances in the management of low-risk febrile neutropenia in children with cancer. Several risk stratification tools for children with febrile neutropenia have been developed, although none of these tools have been directly compared and few have been validated in independent populations. However, there is good evidence that, for pediatric patients with febrile neutropenia at low risk for severe infection, outpatient management is a well tolerated and efficacious alternative to inpatient care. Moreover, major progress has been made in obtaining and understanding perceived quality of life and preferences for outpatient management in pediatric cancer patients. Many parents prefer inpatient management although child quality of life is, in general, anticipated to be higher with outpatient intravenous therapy. Finally, outpatient strategies are more cost-effective as compared with traditional management in hospital. Outpatient management is a well tolerated and cost-effective strategy for low-risk febrile neutropenia in children with cancer, although parental preferences are highly variable for outpatient versus inpatient management. Future research should examine the effectiveness of outpatient strategies through conduct of large cohort studies. Other future work could focus on development of decision aids and other tools to facilitate ambulatory approaches.

Bacterial lung sepsis in patients with febrile neutropenia.

2012-05-01

This review provides an update on microbiological and therapeutic data in febrile neutropenic patients in general and those with bacterial lung sepsis in particular. Although the Infectious Diseases Society of America updated its guidelines on febrile neutropenia in 2010, changing epidemiological factors and the spread of new drug resistance constitutes challenges for initial treatment of this condition. Lung sepsis stands out because of the frequent absence of microbiological identification. We review the use of newly available, novel, broad-spectrum antibiotics (linezolid, tigecycline, daptomycin, etc.) in this indication. Although the incidence of Gram-negative infections in neutropenic fever is leveling off, there is a worrying increase in resistance. New drugs are available but not well studied in febrile neutropenia; daptomycin and tigecycline should not be used in suspected lung sepsis in these patients. New diagnostic tools (such as the procalcitonin assay and the LightCycler SeptiFast assay, Roche Molecular Systems) appear to be unhelpful in febrile neutropenia, although more data on fungal sepsis are required. There are no specific features of the treatment of pneumonia or septic shock in neutropenic fever, but both conditions increase the mortality rate.

Currently, no dengue NS1 detection kit has regulatory approval for the diagnosis of acute dengue fever. Here we report the sensitivity and specificity of the InBios DEN Detect NS1 ELISA using a panel of well characterized human acute fever serum specimens. The InBios DENV Detect NS1 ELISA was tested using a panel composed of 334 serum specimens collected from acute febrile patients seeking care in a Bangkok hospital in 2010 and 2011. Of these patients, 314 were found to have acute dengue by either RT-PCR and/or anti-dengue IgM/IgG ELISA. Alongside the InBios NS1 ELISA kit, we compared the performance characteristics of the BioRad Platelia NS1 antigen kit. The InBios NS1 ELISA Ag kit had a higher overall sensitivity (86% vs 72.8%) but equal specificity (100%) compared to the BioRad Platelia kit. The serological status of the patient significantly influenced the outcome. In primary infections, the InBios NS1 kit demonstrated a higher sensitivity (98.8%) than in secondary infections (83.5%). We found significant variation in the sensitivity of the InBios NS1 ELISA kit depending on the serotype of the dengue virus and also found decreasing sensitivity the longer after the onset of illness, showing 100% sensitivity early during illness, but dropping below 50% by Day 7. The InBios NS1 ELISA kit demonstrated high accuracy when compared to the initial clinical diagnosis with greater than 85% agreement when patients were clinically diagnosed with dengue illness. Results presented here suggest the accurate detection of circulating dengue NS1 by the InBios DENV Detect NS1 ELISA can provide clinicians with a useful tool for diagnosis of early dengue infections.

This study compares the performance of urine dipstick alone with urine microscopy and with both tests combined as a screen for urinary tract infection (UTI) in febrile infants aged 1 to 90 days. We queried the Intermountain Healthcare data warehouse to identify febrile infants with urine dipstick, microscopy, and culture performed between 2004 and 2011. UTI was defined as >50 000 colony-forming units per milliliter of a urinary pathogen. We compared the performance of urine dipstick with unstained microscopy or both tests combined ("combined urinalysis") to identify UTI in infants aged 1 to 90 days. Of 13 030 febrile infants identified, 6394 (49%) had all tests performed and were included in the analysis. Of these, 770 (12%) had UTI. Urine culture results were positive within 24 hours in 83% of UTIs. The negative predictive value (NPV) was >98% for all tests. The combined urinalysis NPV was 99.2% (95% confidence interval: 99.1%-99.3%) and was significantly greater than the dipstick NPV of 98.7% (98.6%-98.8%). The dipstick positive predictive value was significantly greater than combined urinalysis (66.8% [66.2%-67.4%] vs 51.2% [50.6%-51.8%]). These data suggest 8 febrile infants would be predicted to have a false-positive combined urinalysis for every 1 infant with UTI initially missed by dipstick screening. Urine dipstick testing compares favorably with both microscopy and combined urinalysis in febrile infants aged 1 to 90 days. The urine dipstick test may be an adequate stand-alone screen for UTI in febrile infants while awaiting urine culture results. Copyright © 2014 by the American Academy of Pediatrics.

Background During late summer/fall 2014, pediatric cases of acute flaccid myelitis (AFM) occurred in the United States, coincident with a national outbreak of enterovirus D68 (EV-D68)–associated severe respiratory illness. Methods Clinicians and health departments reported standardized clinical, epidemiologic, and radiologic information on AFM cases to the Centers for Disease Control and Prevention (CDC), and submitted biological samples for testing. Cases were ≤21 years old, with acute onset of limb weakness 1 August–31 December 2014 and spinal magnetic resonance imaging (MRI) showing lesions predominantly restricted to gray matter. Results From August through December 2014, 120 AFM cases were reported from 34 states. Median age was 7.1 years (interquartile range, 4.8–12.1 years); 59% were male. Most experienced respiratory (81%) or febrile (64%) illness before limb weakness onset. MRI abnormalities were predominantly in the cervical spinal cord (103/118). All but 1 case was hospitalized; none died. Cerebrospinal fluid (CSF) pleocytosis (>5 white blood cells/μL) was common (81%). At CDC, 1 CSF specimen was positive for EV-D68 and Epstein-Barr virus by real-time polymerase chain reaction, although the specimen had >3000 red blood cells/μL. The most common virus detected in upper respiratory tract specimens was EV-D68 (from 20%, and 47% with specimen collected ≤7 days from respiratory illness/fever onset). Continued surveillance in 2015 identified 16 AFM cases reported from 13 states. Conclusions Epidemiologic data suggest this AFM cluster was likely associated with the large outbreak of EV-D68–associated respiratory illness, although direct laboratory evidence linking AFM with EV-D68 remains inconclusive. Continued surveillance will help define the incidence, epidemiology, and etiology of AFM. PMID:27318332

Specialist paediatric home-based nursing services have been proposed as a cost-effective means of reducing distress resulting from hospital admissions, while enhancing primary care and reducing length of hospital stay. This review is an update of our original review, which was published in 2006. To evaluate specialist home-based nursing services for children with acute and chronic illnesses. We searched the following databases in February 2012: the Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library 2012 Issue 2, Ovid MEDLINE, EMBASE, PsycINFO, CINAHL and Sociological Abstracts. We also searched ClinicalTrials.gov and the WHO International Clinical Trials Registry Platform. No language restrictions were applied. Randomised controlled trials (RCTs) of children from birth to age 18 years with acute or chronic illnesses allocated to specialist home-based nursing services compared with conventional health care. Outcomes included utilisation of health care, physical and mental health, satisfaction, adverse health outcomes and costs. Two review authors extracted data from the studies independently and resolved any discrepancies by recourse to a third author. Meta-analysis was not appropriate because of the clinical diversity of the studies and the lack of common outcome measures. We screened 4226 titles to yield seven RCTs with a total of 840 participants. Participants, interventions and outcomes were diverse. No significant differences were reported in health outcomes; two studies reported a reduction in the hospital stay with no difference in the hospital readmission rates. Three studies reported a reduction in parental anxiety and improvement in child behaviours was reported in three studies. Overall increased parental satisfaction was reported in three studies. Also, better parental coping and family functioning was reported in one study. By contrast, one study each reported no impact on parental burden of care or on functional status of

Saha, Shubhayu; Luber, George

Background: Patients with acute heat illness present primarily to emergency departments (EDs), yet little is known regarding these visits. Objective: We aimed to describe acute heat illness visits to U.S. EDs from 2006 through 2010 and identify factors associated with hospital admission or with death in the ED. Methods: We extracted ED case-level data from the Nationwide Emergency Department Sample (NEDS) for 2006–2010, defining cases as ED visits from May through September with any heat illness diagnosis (ICD-9-CM 992.0–992.9). We correlated visit rates and temperature anomalies, analyzed demographics and ED disposition, identified risk factors for adverse outcomes, and examined ED case fatality rates (CFR). Results: There were 326,497 (95% CI: 308,372, 344,658) cases, with 287,875 (88.2%) treated and released, 38,392 (11.8%) admitted, and 230 (0.07%) died in the ED. Heat illness diagnoses were first-listed in 68%. 74.7% had heat exhaustion, 5.4% heat stroke. Visit rates were highly correlated with annual temperature anomalies (Pearson correlation coefficient 0.882, p = 0.005). Treat-and-release rates were highest for younger adults (26.2/100,000/year), whereas hospitalization and death-in-the-ED rates were highest for older adults (6.7 and 0.03/100,000/year, respectively); all rates were highest in rural areas. Heat stroke had an ED CFR of 99.4/10,000 (95% CI: 78.7, 120.1) visits and was diagnosed in 77.0% of deaths. Adjusted odds of hospital admission or death in the ED were higher among elders, males, urban and low-income residents, and those with chronic conditions. Conclusions: Heat illness presented to the ED frequently, with highest rates in rural areas. Case definitions should include all diagnoses. Visit rates were correlated with temperature anomalies. Heat stroke had a high ED CFR. Males, elders, and the chronically ill were at greatest risk of admission or death in the ED. Chronic disease burden exponentially increased this risk.

Asymmetric dimethylarginine (ADMA) has been recognized as an independent prognostic factor for sepsis mortality in intensive care units. No data are available on kinetics or prognostic value of ADMA in hematological patients. We evaluated the ability of ADMA to act as a predictor for complicated course of febrile neutropenia, defined as bacteremia and/or septic shock in adult hematological patients receiving intensive chemotherapy. This prospective study included 87 adult hematological patients with febrile neutropenia after an intensive chemotherapy for acute myeloid leukemia (AML) or after an autologous stem cell transplantation (ASCT). Plasma ADMA and serum C-reactive protein (CRP) levels were measured from the onset of fever (d0) and for 2 days (d1-d2) thereafter. The levels of ADMA were stable or had only minimal changes during the study period. There was no difference between the levels at any time-point in patients having complicated course compared to those without it. On the other hand, CRP levels were significantly higher on d1 (p = 0.016) in patients with bacteremia and/or septic shock than in those without. ADMA was not able to differentiate hematological patients with a complicated course from those without complications. Elevated ADMA levels are probably associated with organ dysfunction, which is rare in this group of patients, of whom about 95% can be successfully managed at the hematology ward.

Fifty million people are estimated to travel from industrial countries to the tropics annually. In spite of exhaustive studies and widely different diagnosis among returned patients, some cases of febrile illnesses remain without an etiological diagnosis, suggesting that these cases could be due to viral respiratory tract infections. From August 2005 to October 2006, 118 febrile patients without a specific diagnosis in their first visit at the Center for International Health of the Hospital Clínic of Barcelona were included. In all of them, in order to study respiratory viruses, a nasopharyngeal swab was collected. Clinical and radiological features and epidemiological data, as well as other samples for microbiologic studies, were also collected during consultation. Based on the physician's judgment at the time of consultation, patients were classified into four groups: respiratory symptoms (62%), febrile syndrome with nonspecific symptoms (24%), digestive symptoms (10%), and patients presenting both respiratory and digestive symptoms (4%). A pathogen microorganism was detected in 61 patients (52%). Respiratory viruses were detected in 44 out of 118 (37%) travelers included in the study, representing 56% of the patients with respiratory symptoms. The most frequently viruses detected were influenza virus (38%), rhinovirus (23%), adenovirus (9%), and respiratory syncytial virus (9%). Respiratory viruses have been shown to play an important role in imported fever. In light of the fact that international tourism is an increasing phenomenon, new strategies to prevent the spread of respiratory viruses should be considered, specially for influenza when a vaccine is available.

Research has implicated that changes in zinc (Zn) metabolism may be associated with the biological underpinnings of eating disorders, in particular anorexia nervosa. However, to date research on the role of Zn in patients with bulimia nervosa (BN) is scarce. We aimed to explore serum Zn concentrations in young patients with BN, with a focus on the stage of the disorder, comparing acutely ill and recovered patients with BN with healthy controls. Serum Zn concentrations were obtained from healthy controls and from acutely ill and remitted young patients with BN. Mean duration of remission was 4.0±3.5 years. Remitted patients showed elevated serum Zn concentrations when compared to controls (Cohen's d=2.022), but concentrations were still in the normal range. Acutely ill patients also had higher serum Zn levels when compared to controls (all values still being within the reference range, Cohen's d=0.882). There was no difference between acutely ill and remitted patients with BN in serum Zn concentrations. Of note, remitted patients had a significantly higher body weight when compared to the other two groups. Overall, there were no significant differences in dietary preferences with regard to Zn containing foods between the groups. The present study provides preliminary evidence that the underlying factors for changes in Zn serum concentrations in young patients with BN do not vary with regard to the stage of illness (acute versus remitted BN). Further prospective research is needed in order to disentangle the possible interplay between serum Zn status and bulimic eating behaviors.

Many adult patients hospitalised with acute respiratory illness have viruses detected but the overall importance of viral infection compared to bacterial infection is unclear. Patients were recruited from two acute hospital sites in Leicester (UK) over 3 successive winters. Samples were taken for viral and bacterial testing. Of the 780 patients hospitalised with acute respiratory illness 345 (44%) had a respiratory virus detected. Picornaviruses were the most commonly isolated viruses (detected in 23% of all patients). Virus detection rates exceeded 50% in patients with exacerbation of asthma (58%), acute bronchitis and Influenza-like-illness (64%), and ranged from 30 to 50% in patients with an exacerbation of COPD (38%), community acquired pneumonia (36%) and congestive cardiac failure (31%). Bacterial detection was relatively frequent in patients with exacerbation of COPD and pneumonia (25% and 33% respectively) but was uncommon in all other groups. Antibiotic use was high across all clinical groups (76% overall) and only 21% of all antibiotic use occurred in patients with detectable bacteria. Respiratory viruses are the predominant detectable aetiological agents in most hospitalised adults with acute respiratory illness. Antibiotic usage in hospital remains excessive including in clinical conditions associated with low rates of bacterial detection. Efforts at reducing excess antibiotic use should focus on these groups as a priority. Registered International Standard Controlled Trial Number: 21521552.

2014-10-01

Dysphagia is a severe complication in critically ill patients and affects more than half the patients in an intensive care unit. Dysphagia also has a strong impact on morbidity and mortality. Risk factors for the development of dysphagia are neurological diseases, age >55-70 years, intubation >7 days and sepsis. With increasing numbers of long-term survivors chronic dysphagia is becoming an increasing problem. There is not much knowledge on the influence of specific diseases, including the direct impact of sepsis on the development of dysphagia. Fiberoptic evaluation of swallowing is a standardized tool for bedside evaluation, helping to plan swallowing training during the acute phase and to decrease the rate of chronic dysphagia. For evaluation of chronic dysphagia even more extensive diagnostic tools as well as several options of stepwise rehabilitation using restitution, compensation and adaption strategies for swallowing exist. Currently it seems that these options are not being sufficiently utilized. In general, there is a need for controlled clinical trials analyzing specific swallowing rehabilitation concepts for former critically ill patients and long-term survivors.

Emergency management of acute abdomen in children.

PubMed

Balachandran, Binesh; Singhi, Sunit; Lal, Sadhna

2013-03-01

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

Other than influenza, little is known about the consequences of viral acute respiratory illness (ARI) on pregnant women and fetuses. Our objectives were to determine the frequency of ARI due to respiratory viruses and the associated clinical outcomes during pregnancy. Pregnant women in their second or third trimester were enrolled if they reported having symptoms of ARI or were healthy within the preceding 2 weeks. Nasopharyngeal secretions were evaluated for respiratory viruses by molecular diagnostic assays. Clinical outcomes were evaluated at enrollment and via a follow-up telephone-based questionnaire 2 weeks later. There were 155 pregnant participants, with 81 ARI cases and 91 healthy controls. Acute lower respiratory tract illness (ALRTI) was identified in 29 cases (36%). Human rhinovirus (HRV), respiratory syncytial virus (RSV), and influenza virus accounted for 75% of virus-positive cases of ALRTI. Cases with ALRTI often reported a longer duration of illness, history of allergies, symptoms of wheezing, shortness of breath, or chest pain, and use of prescription medication. Two cases with ALRTI reported decreased fetal movement; a third case with ALRTI was hospitalized. In over one third of ARI cases, participants had symptoms consistent with ALRTI. Infection with HRV, RSV, or influenza virus was commonly detected in patients with ALRTI. Viral ALRTI during pregnancy appears to be common and is associated with significant morbidity.

Although the severe acute respiratory illness (SARI) case definition is increasingly used for inpatient influenza surveillance, pneumonia is a more familiar term to clinicians and policymakers. We evaluated WHO case definitions for severe acute respiratory illness (SARI) and pneumonia (Integrated Management of Childhood Illnesses (IMCI) for children aged <5 years and Integrated Management of Adolescent and Adult Illnesses (IMAI) for patients aged ≥13 years) for detecting laboratory-confirmed influenza among hospitalized ARI patients. Sensitivities were 84% for SARI and 69% for IMCI pneumonia in children aged <5 years and 60% for SARI and 57% for IMAI pneumonia in patients aged ≥13 years. Clinical pneumonia case definitions may be a useful complement to SARI for inpatient influenza surveillance. © 2016 The Authors.

Comorbid depression is highly prevalent in geriatric patients and associated with functional loss, frequent hospital re-admissions, and a higher mortality rate. Cognitive behavioral psychotherapy (CBT) has shown to be effective in older depressive patients living in the community. To date, CBT has not been applied to older patients with acute physical illness and comorbid depression. To evaluate the effectiveness of CBT in depressed geriatric patients, hospitalized for acute somatic illness. Randomized controlled trial with waiting list control group. Postdischarge intervention in a geriatric day clinic; follow-up evaluations at the patients' homes. A total of 155 randomized patients, hospitalized for acute somatic illness, aged 82 ± 6 years and suffering from depression [Hospital Anxiety and Depression Scale (HADS) scores >7]. Exclusion criteria were dementia, delirium, and terminal state of medical illness. Fifteen, weekly group sessions based on a CBT manual. Commencement of psychotherapy immediately after discharge in the intervention group and a 4-month waiting list interval with usual care in the control group. HADS depression total score after 4 months. Secondary endpoints were functional, cognitive, psychosocial and physical status, resource utilization, caregiver burden, and amount of contact with physician. The intervention group improved significantly in depression scores (HADS baseline 18.8; after 4 months 11.4), whereas the control group deteriorated (HADS baseline 18.1; after 4 months 21.6). Significant improvement in the intervention group, but not in the control group, was observed for most secondary outcome parameters such as the Barthel and Karnofsky indexes. Intervention effects were less pronounced in patients with cognitive impairment or acute fractures. CBT is feasible and highly effective in geriatric patients. The benefits extend beyond effective recovery and include improvement in physical and functional parameters. Early diagnosis

Bali, Indonesia presents significant infectious and non-infectious health risks for Australian travellers. Understanding this spectrum of illnesses has the potential to assist clinicians in evaluating unwell returning travellers and guide provision of pre-travel advice. To describe the spectrum of illnesses seen in returned travellers from Bali. Using a novel text mining approach, we performed a retrospective, observational study of all adult emergency department (ED) presentations to a metropolitan health service in Melbourne, from 2011-2015. Outcome measures included demographic, clinical and laboratory features of travel-related illnesses. A total of 464 patients met inclusion criteria. Gastroenteritis (119/464, 26%), systemic febrile illness (88/464, 19%) and respiratory tract infection (51/464, 11%) were the most common diagnoses. Dengue was the most common laboratory-confirmed diagnosis (25/464, 5%). No cases of malaria were identified. Common non-infectious presentations included traumatic injury (47/464, 10%) and animal bites requiring rabies post-exposure prophylaxis (29/464, 6%). 110 patients (24%) were admitted to hospital; those presenting with systemic febrile illness were more likely to be admitted compared to those presenting with other illnesses (OR 3.42, CI 2.02-5.75, p<0.001). This is the first study to use a text mining approach to identify and describe ED presentations related to diseases acquired in Bali by Australian travellers. While infections are important causes of illness, trauma and animal bites account for a significant number of hospital presentations. Our findings contribute to knowledge on the health risks for travellers to Bali, and will assist clinicians in relevant pre- and post-travel evaluations. This article is protected by copyright.

OSHA predicted the original chemical Hazard Communication Standard (HCS) would cumulatively reduce the lost workday acute injury/illness rate for exposure events by 20% over 20 years and reduce exposure to chemical carcinogens. JoinPoint trend software identified changes in the rate of change of BLS rates for days away from work for acute injuries/illnesses during 1992-2009 for manufacturing and nonmanufacturing industries for both chemical, noxious or allergenic injury exposure events and All other exposure events. The annual percent change in the rates was used to adjust observed numbers of cases to estimate their association with the standard. A case-control study of EPA's Toxic Release Inventory 1988-2009 data compared carcinogen and non-carcinogens' releases. The study estimates that the HCS was associated with a reduction in the number of acute injuries/illnesses due to chemical injury exposure events over the background rate in the range 107,569-459,395 (Hudson method/modified BIC model) depending on whether the HCS is treated as a marginal or sole factor in the decrease. Carcinogen releases have declined at a substantially faster rate than control non-carcinogens. The previous HCS standard was associated with significant reductions in chemical event acute injuries/illnesses and chemical carcinogen exposures. © 2013 Wiley Periodicals, Inc.

Background: Pesticides are widely used in agriculture, and off-target pesticide drift exposes workers and the public to harmful chemicals. Objective: We estimated the incidence of acute illnesses from pesticide drift from outdoor agricultural applications and characterized drift exposure and illnesses. Methods: Data were obtained from the National Institute for Occupational Safety and Health’s Sentinel Event Notification System for Occupational Risks–Pesticides program and the California Department of Pesticide Regulation. Drift included off-target movement of pesticide spray, volatiles, and contaminated dust. Acute illness cases were characterized by demographics, pesticide and application variables, health effects, and contributing factors. Results: From 1998 through 2006, we identified 2,945 cases associated with agricultural pesticide drift from 11 states. Our findings indicate that 47% were exposed at work, 92% experienced low-severity illness, and 14% were children (< 15 years). The annual incidence ranged from 1.39 to 5.32 per million persons over the 9-year period. The overall incidence (in million person-years) was 114.3 for agricultural workers, 0.79 for other workers, 1.56 for nonoccupational cases, and 42.2 for residents in five agriculture-intensive counties in California. Soil applications with fumigants were responsible for the largest percentage (45%) of cases. Aerial applications accounted for 24% of cases. Common factors contributing to drift cases included weather conditions, improper seal of the fumigation site, and applicator carelessness near nontarget areas. Conclusions: Agricultural workers and residents in agricultural regions had the highest rate of pesticide poisoning from drift exposure, and soil fumigations were a major hazard, causing large drift incidents. Our findings highlight areas where interventions to reduce off-target drift could be focused. PMID:21642048

We retrospectively evaluated the use of computed tomography abdomen and pelvis (CTAP) in febrile neutropenic autologous stem cell transplant (ASCT) and acute myeloid leukaemia (AML) patients. CTAP was more common in ASCT patients (59%) compared with AML (31%; P  < 0.001). Although abnormal findings were reported in 51%, only 10% resulted in therapy change (addition of anaerobic antibiotic/bowel rest), which would have otherwise been instituted based on clinical grounds. CTAP in these patients rarely provide useful information unsuspected clinically. © 2016 Royal Australasian College of Physicians.

Scrub typhus is a re-emerging mite-borne rickettsiosis, which continues to be underdiagnosed, with lethal consequences. The present study was conducted to determine the seasonality, clinical presentation and predictors of mortality in patients with scrub typhus at a tertiary care teaching hospital in northern India. Scrub typhus was suspected in patients attending the hospital as per the standard case definition and serological evidence was obtained by performing an IgM ELISA. A total of 284 patients with scrub typhus from urban and rural areas were seen, predominantly from July to November. The most common clinical presentation was a bilateral community-acquired pneumonia (CAP), which resembled pneumonia due to atypical pathogens and often progressed to acute respiratory distress syndrome (ARDS). An acute undifferentiated febrile illness (AUFI) or a febrile illness associated with altered sensorium, aseptic meningitis, shock, abdominal pain, gastrointestinal bleeding or jaundice was also seen. Eschars were seen in 17 per cent of patients, and thrombocytopenia, transaminitis and azotaemia were frequent. There were 24 deaths (8.5%) caused predominantly by ARDS and multi-organ dysfunction. The mortality in patients with ARDS was high (37%). ARDS [odds ratio (OR)=38.29, 95% confidence interval (CI): 9.93, 147.71] and acute kidney injury (OR=8.30, 95% CI: 2.21, 31.21) were the major predictors of death. The present findings indicate that scrub typhus may be considered a cause of CAP, ARDS, AUFI or a febrile illness with multisystem involvement, in Uttarakhand and Uttar Pradesh, especially from July to November. Empiric therapy of CAP may include doxycycline or azithromycin to ensure coverage of underlying unsuspected scrub typhus.

Information about the development of febrile neutropenia in patients with solid tumors remains insufficient. In this study, we tried to identify the risk factors for refractory febrile neutropenia in patients with lung cancer. A total of 59 neutropenic fever episodes associated with anti-tumor chemotherapy for lung cancer were retrospectively analyzed. We compared patient characteristics according to their initial response to treatment with antibiotics. For 34 of 59 (58%) episodes a response to initial antibiotics was obtained whereas 25 of 59 (42%) were refractory to treatment. Multivariate analysis demonstrated independent risk factors for refractory febrile neutropenia with lung cancer. These risk factors were the severity of febrile neutropenia (odds ratio (OR) 6.11; 95% confidence interval (CI) 1.85-20.14) and C-reactive protein more than 10 mg/dl (OR 4.39; 95% CI 1.22-15.74). These factors could predict outcome for patients with lung cancer who develop refractory febrile neutropenia.

The study was aimed to evaluate the malaria over/underdiagnosis and over/underprescription of antimalarial drugs. Between February and March 2007 blood samples were collected from 336 non-severe febrile outpatients attended in two peripheral Tanzanian hospitals. Microscopy and a rapid diagnostic test (RDT) were done locally and the accuracy evaluated by qualitative polymerase chain reaction (PCR) for Plasmodium spp. The testing was performed at National Institute for Infectious Diseases Lazzaro Spallanzani (INMI), Rome, Italy. As a result of PCR, we identified 26 malaria cases out of 336 (7.7%) patients. Microscopy and RDT accuracies were 93.5% and 97.6%, respectively. Overprescription and underdiagnosis rates were 29.3% and 30.8%, respectively. On-field training, clinical management of febrile illness, and malaria microscopy in remote settings should be considered.

Since Vi antigen is limited primarily to Salmonella typhi, it has been thought that detection of the antigen may be a useful method for diagnosing acute typhoid fever. The slide coagglutination method and enzyme-linked immunosorbent assay have recently been suggested as ways to detect small quantities of Vi antigen in urine. In Santiago, Chile, we compared the results of these two methods in patients with acute typhoid fever, paratyphoid fever, and other febrile illnesses and in afebrile control subjects. Using a cut-off value that maximally separated typhoid patients from controls, the enzyme-linked immunosorbent assay was positive in 62.4% of 141 patients with culture-proven typhoid infections and in 13.2% of 159 afebrile control subjects. The enzyme-linked immunosorbent assay was false positive in 64.7% of 34 culture-proven paratyphoid A or B patients and 47.1% of 21 patients with other nontyphoidal febrile illnesses. The coagglutination test was positive in 34% of typhoid patients, 14% of afebrile control subjects, and 46% of febrile control subjects. We conclude that these tests when performed with the Vi antibodies employed in this study are of little value for the diagnosis of typhoid fever in this setting. PMID:6630465

Septic acute kidney injury (AKI) accounts for more than half of all cases of AKI in critically ill children. The renal histology was found to alter the management in more than two-third of cases of adult acute renal failure. Better insight into the pathogenesis of pediatric septic AKI could be based on developing a clearer appreciation of the histopathological changes. No comprehensive study of the histopathological features of septic AKI in critically ill children has yet been performed. This retrospective observational study was conducted at a level-III pediatric intensive care unit (PICU) from June 2013 to July 2014. Children (<13 years of age) who had expired due to sepsis and AKI and had post-mortem renal biopsies were included. Sepsis and AKI were defined according to the International pediatric sepsis consensus conference and Acute Kidney Injury Network (AKIN) definition and classification system, respectively. A total of 708 patients were admitted to the PICU during the study period, with mortality of 24 % (n = 170) and 62 complete data of post-mortem renal biopsies were included. The median (IQR) age was 12 (4.8-36) months, pediatric risk of mortality score (PRISM) III was 14 (12-18) and the time to biopsy after death was 24 (18-26) minutes. Normal histology was the most common change 41.9 % (n = 26), followed by acute tubular necrosis (ATN) 30.6 % (n = 19). A combination of changes involving tubules, glomeruli, interstitium, and blood vessels was noted in 21 % (n = 13) of the specimens. Eight percent (n = 5) of the specimens had features consistent with thrombotic microangiopathy. Normal histology was noted in 15.4 % (n = 4/26), 50 % (n = 13/26), and 34.6 % (n = 9/26) of AKI stage-I, II, and III, respectively. The most common renal histopathological change in septic AKI in critically ill children was normal histology followed by ATN.

Diagnostic error and delay are critical impediments to the safety of critically ill patients. Checklist for early recognition and treatment of acute illness and injury (CERTAIN) has been developed as a tool that facilitates timely and error-free evaluation of critically ill patients. While the focused history is an essential part of the CERTAIN framework, it is not clear how best to choreograph this step in the process of evaluation and treatment of the acutely decompensating patient. An un-blinded crossover clinical simulation study was designed in which volunteer critical care clinicians (fellows and attendings) were randomly assigned to start with either obtaining a focused history choreographed in series (after) or in parallel to the primary survey. A focused history was obtained using the standardized SAMPLE model that is incorporated into American College of Trauma Life Support (ATLS) and Pediatric Advanced Life Support (PALS). Clinicians were asked to assess six acutely decompensating patients using pre - determined clinical scenarios (three in series choreography, three in parallel). Once the initial choreography was completed the clinician would crossover to the alternative choreography. The primary outcome was the cognitive burden assessed through the NASA task load index. Secondary outcome was time to completion of a focused history. A total of 84 simulated cases (42 in parallel, 42 in series) were tested on 14 clinicians. Both the overall cognitive load and time to completion improved with each successive practice scenario, however no difference was observed between the series versus parallel choreographies. The median (IQR) overall NASA TLX task load index for series was 39 (17 - 58) and for parallel 43 (27 - 52), p = 0.57. The median (IQR) time to completion of the tasks in series was 125 (112 - 158) seconds and in parallel 122 (108 - 158) seconds, p = 0.92. In this clinical simulation study assessing the incorporation of a focused history

To examine the independent contribution of individual, community and state-level factors to health care service utilization for children with acute childhood illnesses in Nigeria. The study was based on secondary analyses of cross-sectional population-based data from the 2013 Nigeria Demographic and Health Survey (DHS). Multilevel logistic regression models were applied to the data on 6,427 under-five children who used or did not use health care service when they were sick (level 1), nested within 896 communities (level 2) from 37 states (level 3). About one-quarter of the mothers were between 15 and 24 years old and almost half of them did not have formal education (47%). While only 30% of the children utilized health service when they were sick, close to 67% lived in the rural area. In the fully adjusted model, mothers with higher education attainment (Adjusted odds ratio [aOR] = 1.63; 95% credible interval [CrI] = 1.31-2.03), from rich households (aOR = 1.76; 95% CrI = 1.35-2.25), with access to media (radio, television or magazine) (aOR = 1.18; 95% CrI = 1.08-1.29), and engaging in employment (aOR = 1.18; 95% CrI = 1.02-1.37) were significantly more likely to have used healthcare services for acute childhood illnesses. On the other hand, women who experienced difficulty getting to health facilities (aOR = 0.87; 95% CrI = 0.75-0.99) were less likely to have used health service for their children. Our findings highlight that utilization of healthcare service for acute childhood illnesses was influenced by not only maternal factors but also community-level factors, suggesting that public health strategies should recognise this complex web of individual composition and contextual composition factors to guide provision of healthcare services. Such interventions could include: increase in female school enrolment, provision of interest-free loans for small and medium scale enterprises, introduction of mobile clinics and establishment of more primary health care

[Critical illness polyneuropathy and myopathy].

PubMed

Critical Illness Polyneuropathy (CIP) and Myopathy (CIM), either singly or in combination, are a common complication of critical illness. Both disorders may lead to severe weakness and require mechanical ventilation. CIP, as initially described by Bolton et al., in 1984, is a sensorimotor polyneuropathy that is often a complication of sepsis and multiorgan failure. In Japan, Horinouchi et al., first reported a case in 1994. CIM has been referred to by a number of different terms (acute quadriplegic myopathy, thick filament myopathy, acute necrotizing myopathy of intensive care, rapidly evolving myopathy with myosin-deficiency fibers) in the literature. A variety of serious problems (e.g., pneumonia, severe asthma, and lung or liver transplantation) and the concomitant use of high-dose intravenous corticosteroids and nondepolarizing neuromuscular blocking agents predispose to CIM. In Japan, Kawada et al., reported a first case as acute quadriplegic myopathy in 2000. There is no specific treatment for CIP and CIM. Minimizing the use of corticosteroids and nondepolarizing neuromuscular blocking agents in a critical illness setting may prove helpful in preventing the occurrence of these disorders. The prognosis is directly related to the age of the patient and the seriousness of the underlying illness.

Enteroviruses can cause outbreaks of severe acute respiratory illness (SARI) and EV-A, -B, -C, and -D species have different pathogenic profiles and circulation patterns. We aimed to characterize and determine the prevalence of enterovirus genotypes among South African patients with respiratory illness and controls during June 2012 to July 2014. Syndromic SARI and influenza-like illness (ILI) surveillance was performed at two sentinel sites. At each site nasopharyngeal/oropharyngeal specimens were collected from SARI and ILI patients as well as controls. Specimens were tested for enterovirus by real-time PCR. Positive specimens were further genotyped by sequencing a region of the VP1 gene. The prevalence of enterovirus was 5.8% (87/1494), 3.4% (103/3079), and 3.4% (46/1367) among SARI, ILI, and controls, respectively (SARI/controls, P = 0.002 and ILI/control, P = 0.973). Among the 101/236 (42.8%) enterovirus-positive specimens that could be genotyped, we observed a high diversity of circulating enterovirus genotypes (a total of 33 genotypes) from all four human enterovirus species with high prevalence of Enterovirus-B (60.4%; 61/101) and Enterovirus-A (21.8%; 22/101) compared to Enterovirus-C (10.9%; 11/101) and Enterovirus-D (6.9%; 7/101) (P = 0.477). Of the enterovirus genotypes identified, Echovirus 30 (9.9%, 10/101), Coxsackie virus B5 (7.9%, 8/101) and Enterovirus-D68 (6.9%, 7/101) were most prevalent. There was no difference in disease severity (SARI or ILI compared to controls) between the different enterovirus species (P = 0.167). We observed a high number of enterovirus genotypes in patients with respiratory illness and in controls from South Africa with no disease association of EV species with disease severity. © 2017 Wiley Periodicals, Inc.

This large population-based cohort study evaluated the association between certain critical illnesses and the incidence of newly diagnosed type 2 diabetes mellitus (T2DM) in Taiwan. Data were obtained from the Taiwan National Health Insurance Research Database. According to age, sex, and propensity score-matching, a cohort comprising 9528 patients with critical illness, including septicemia, septic shock, acute myocardial infarction (AMI), and stroke, and a control cohort of 9528 patients with no critical illness were identified. Cox proportional-hazard regression and competing-risk regression models were employed to evaluate the risk of developing T2DM. With the median follow-up periods (interquartile range) of 3.86 (1.64-6.93) and 5.12 (2.51-8.13) years for the patients in the critical illness and control cohorts, respectively, the risk of developing T2DM in the critical illness cohort was significantly higher than in the control cohort (adjusted hazard ratio, aHR = 1.32; 95% confidence interval, CI 1.16-1.50). In the multivariate competing-risk regression models, the aHR of T2DM was 1.58 (95% CI 1.45-1.72) in the critical illness cohort. Moreover, among the patients with these critical illnesses, those with septicemia or septic shock exhibited the highest risk of developing T2DM (aHR = 1.51, 95% CI 1.37-1.67), followed by AMI compared with the control cohort. Our results suggest that patients with certain critical illnesses are associated with a high risk of developing T2DM. Clinicians should be aware of this association and intensively screen for T2DM in patients following diagnosis of critical illness.

Background Research has implicated that changes in zinc (Zn) metabolism may be associated with the biological underpinnings of eating disorders, in particular anorexia nervosa. However, to date research on the role of Zn in patients with bulimia nervosa (BN) is scarce. Objective We aimed to explore serum Zn concentrations in young patients with BN, with a focus on the stage of the disorder, comparing acutely ill and recovered patients with BN with healthy controls. Methods Serum Zn concentrations were obtained from healthy controls and from acutely ill and remitted young patients with BN. Mean duration of remission was 4.0±3.5 years. Results Remitted patients showed elevated serum Zn concentrations when compared to controls (Cohen’s d=2.022), but concentrations were still in the normal range. Acutely ill patients also had higher serum Zn levels when compared to controls (all values still being within the reference range, Cohen’s d=0.882). There was no difference between acutely ill and remitted patients with BN in serum Zn concentrations. Of note, remitted patients had a significantly higher body weight when compared to the other two groups. Overall, there were no significant differences in dietary preferences with regard to Zn containing foods between the groups. Conclusion The present study provides preliminary evidence that the underlying factors for changes in Zn serum concentrations in young patients with BN do not vary with regard to the stage of illness (acute versus remitted BN). Further prospective research is needed in order to disentangle the possible interplay between serum Zn status and bulimic eating behaviors. PMID:29089768

Urinary tract infection (UTI) is one of the most common complications after radical cystectomy and orthotopic neobladder reconstruction. This study investigated the incidence and implicated pathogen of febrile UTI after ileal neobladder reconstruction and identify clinical and urodynamic parameters associated with febrile UTI. From January 2001 to May 2015, 236 patients who underwent radical cystectomy and ileal neobladder were included in this study. Fifty-five episodes of febrile UTI were identified in 46 patients (19.4%). The probability of febrile UTI was 17.6% and 19.8% at 6 months and 24 months after surgery, respectively. While, Escherichia coli was the most common implicated pathogen (22/55, 40.0%), Enterococcus spp. were the most common pathogen during the first month after surgery (18/33, 54.5%). In multivariate logistic regression analysis, ureteral stricture was an independent risk factor associated with febrile UTI (OR 5.93, P = 0.023). However, ureteral stricture accounted for only 6 episodes (10.9%, 6/55) of febrile UTI. Most episodes of febrile UTI occurred within 6 months after surgery. Thus, to identify risk factors associated with febrile UTI in the initial postoperative period, we assessed videourodynamics within 6 months after surgery in 38 patients. On videourodyamic examination, vesicoureteral reflux (VUR) was identified in 16 patients (42.1%). The rate of VUR presence in patients who had febrile UTI was not significantly different from those in patients without febrile UTI (50% vs. 39.3%, P = 0.556). Patients with febrile UTI had significantly larger residual urine volume (212.0 ± 193.7 vs. 90.5 ± 148.2, P = 0.048) than those without. E. coli and Enterococcus spp. are common pathogens and ureteral stricture and residual urine are risk factors for UTI after ileal neobladder reconstruction.

The early use of break-bone fever (Quebranta huesos, 1771) and dengue (1801) in Spanish.

The appellation of break-bone fever for dengue is attributed to the popular name given to the disease in the first described epidemic of an illness that is clinically compatible with dengue in Philadelphia in 1780. The origin of the word dengue as the name of an illness is currently attributed to the Swahili phrase Ka dinga pepo, thought to have crossed from Africa to the Caribbean in 1827; in Cuba this phrase was popularly identified with the Spanish word dengue. This article presents documents from Spanish archives that indicate the use of quebranta huesos (break-bone) by a physician in Puerto Rico to describe a febrile illness in 1771, and the use of the term dengue by the Queen of Spain in 1801 to describe an acute febrile illness with bone and joint pains, hemorrhage, and jaundice. These texts are evidence of a more generalized use of the term break-bone than previously recognized, and conversely, the specifically Spanish origin of dengue as the name for an illness.

Abstract Background. Hypophosphatemia in critically ill patients may be exacerbated by renal replacement therapy (RRT). We aimed to identify risk factors and adverse outcomes associated with hypophosphatemia in intensive care patients treated with RRT for acute kidney injury (AKI). Methods. This was a secondary analysis of data from a single-center prospective cohort study of medical and surgical intensive care patients with RRT for AKI between 18 December 2010 and 3 April 2013. Demographic, comorbidity, laboratory and RRT data were retrieved from patient case notes and electronic medical records. Outcomes assessed were hypophosphatemia (serum phosphate <0.94 mmol/L) during RRT, intensive care unit (ICU) mortality, and duration of mechanical ventilation and vasopressor support. Results. Among 96 patients who received acute RRT, 25 (26.0%) developed hypophosphatemia. On multivariate logistic regression, serum phosphate at RRT initiation [adjusted odds ratio (OR) 0.29, 95% confidence interval (CI) (0.09, 0.91), P = 0.03] was independently associated with hypophosphatemia during acute RRT. Patients with hypophosphatemia during RRT required longer ventilatory support [median 12 (interquartile range: 8, 17) days versus 5 (3, 9) days, P < 0.001] and vasopressor support [5 (4, 15) days versus 2 (2, 6) days, P = 0.003] compared with those without hypophosphatemia but there was no significant difference in ICU mortality [5 patients (20.0%) versus 24 patients (33.8%), P = 0.20]. Hypophosphatemia during RRT was independently associated with prolonged mechanical ventilation (≥7 days) [adjusted OR 14.0, 95% CI (1.37, 143.90), P = 0.03]. Conclusion. Hypophosphatemia is common during acute RRT for critically ill patients and was associated with adverse clinical outcomes. PMID:28616212

To examine the association between falls in hospital and new placement in a nursing home among older people hospitalized with acute illness. This prospective cohort study of 2,945 consecutive patients discharged alive from an acute geriatric medicine service used multivariate logistic regression to model the association between one or more falls and nursing home placement (primary analysis). Secondary analyses stratified falls by injury and occurrence of multiple falls. Demographic, medical, and frailty measures were considered in adjusted models. The mean age of all patients was 82.8±7.6 years and 94% were admitted through the emergency department. During a median length of stay (LOS) of 11 days, 257 (8.7%) patients had a fall. Of these, 66 (25.7%) sustained an injury and 53 (20.6%) had two or more falls. Compared with nonfallers, fallers were more likely to be placed in a nursing home (odds ratio [OR]: 2.03, 95% confidence interval [CI]: 1.37-3.00), after adjustment for age, sex, frailty, and selected medical variables (including dementia and delirium). Patients without injury (OR: 1.83, 95% CI: 1.17-2.85) and those with injury (OR: 2.35, 95% CI: 1.15-4.77) were also more likely to be placed. Patients who fell had a longer LOS (median 19 days vs 10 days; P<0.001). This study of older people in acute care shows that falls in the hospital are significantly associated with new placement in a nursing home. Given the predominantly negative experiences and the financial costs associated with placement in a nursing home, fall prevention should be a high priority in older people hospitalized with acute illness.

To review the available knowledge on epidemiology and diagnoses of acute infections in children aged 2 to 59 months in primary care setting and develop an electronic algorithm for the Integrated Management of Childhood Illness to reach optimal clinical outcome and rational use of medicines. A structured literature review in Medline, Embase and the Cochrane Database of Systematic Review (CDRS) looked for available estimations of diseases prevalence in outpatients aged 2-59 months, and for available evidence on i) accuracy of clinical predictors, and ii) performance of point-of-care tests for targeted diseases. A new algorithm for the management of childhood illness (ALMANACH) was designed based on evidence retrieved and results of a study on etiologies of fever in Tanzanian children outpatients. The major changes in ALMANACH compared to IMCI (2008 version) are the following: i) assessment of 10 danger signs, ii) classification of non-severe children into febrile and non-febrile illness, the latter receiving no antibiotics, iii) classification of pneumonia based on a respiratory rate threshold of 50 assessed twice for febrile children 12-59 months; iv) malaria rapid diagnostic test performed for all febrile children. In the absence of identified source of fever at the end of the assessment, v) urine dipstick performed for febrile children <2 years to consider urinary tract infection, vi) classification of 'possible typhoid' for febrile children >2 years with abdominal tenderness; and lastly vii) classification of 'likely viral infection' in case of negative results. This smartphone-run algorithm based on new evidence and two point-of-care tests should improve the quality of care of <5 year children and lead to more rational use of antimicrobials.

Acute eosinophilic pneumonia (AEP) is a rapid onset and severe respiratory illness characterized by acute febrile respiratory insufficiency, eosinophilic infiltration in the lungs and unique findings on chest imaging. Difficulty in differentiating from other respiratory distress caused by community-acquired pneumonia may result in a delayed diagnosis or treatment with empirical antibiotics. Sixteen-year-old boy who developed AEP with marked eosinophilia in bronchoalveolar lavage fluid (BALF, 36.6%), decreased diffusion capacity of the lung for carbon monoxide (62%) and unique radiological findings. Although he initially denied tobacco use, on repeated thorough clinical history questioning, he eventually admitted beginning smoking 19 days before the onset of symptoms with gradually increasing frequency. His symptoms resolved quickly without use of antibiotics after cessation of tobacco and treatment with corticosteroids. Careful clinical history taking regarding tobacco use combined with early examination of BALF and recognition of unique radiological findings are critical for proper management of AEP.

Microcirculatory alterations are associated with adverse outcome in subsets of critically ill patients. The prevalence and significance of microcirculatory alterations in the general ICU population are unknown. We studied the prevalence of microcirculatory alterations in a heterogeneous ICU population and its predictive value in an integrative model of macro- and microcirculatory variables. Multicenter observational point prevalence study. The Microcirculatory Shock Occurrence in Acutely ill Patients study was conducted in 36 ICUs worldwide. A heterogeneous ICU population consisting of 501 patients. None. Demographic, hemodynamic, and laboratory data were collected in all ICU patients who were 18 years old or older. Sublingual Sidestream Dark Field imaging was performed to determine the prevalence of an abnormal capillary microvascular flow index (< 2.6) and its additional value in predicting hospital mortality. In 501 patients with a median Acute Physiology and Chronic Health Evaluation II score of 15 (10-21), a Sequential Organ Failure Assessment score of 5 (2-8), and a hospital mortality of 28.4%, 17% exhibited an abnormal capillary microvascular flow index. Tachycardia (heart rate > 90 beats/min) (odds ratio, 2.71; 95% CI, 1.67-4.39; p < 0.001), mean arterial pressure (odds ratio, 0.979; 95% CI, 0.963-0.996; p = 0.013), vasopressor use (odds ratio, 1.84; 95% CI, 1.11-3.07; p = 0.019), and lactate level more than 1.5 mEq/L (odds ratio, 2.15; 95% CI, 1.28-3.62; p = 0.004) were independent risk factors for hospital mortality, but not abnormal microvascular flow index. In reference to microvascular flow index, a significant interaction was observed with tachycardia. In patients with tachycardia, the presence of an abnormal microvascular flow index was an independent, additive predictor for in-hospital mortality (odds ratio, 3.24; 95% CI, 1.30-8.06; p = 0.011). This was not true for nontachycardic patients nor for the total group of patients. In a heterogeneous ICU

Understanding healthcare-seeking patterns for respiratory illness can help improve estimations of disease burden and inform public health interventions to control acute respiratory disease in Indonesia. The objectives of this study were to describe healthcare-seeking behaviors for respiratory illnesses in one rural and one urban community in Western Java, and to explore the factors that affect care seeking. From February 8, 2012 to March 1, 2012, a survey was conducted in 2520 households in the East Jakarta and Bogor districts to identify reported recent respiratory illnesses, as well as all hospitalizations from the previous 12-month period. We found that 4% (10% of those less than 5 years) of people had respiratory disease resulting in a visit to a healthcare provider in the past 2 weeks; these episodes were most commonly treated at government (33%) or private (44%) clinics. Forty-five people (0.4% of those surveyed) had respiratory hospitalizations in the past year, and just over half of these (24/45, 53%) occurred at a public hospital. Public health programs targeting respiratory disease in this region should account for care at private hospitals and clinics, as well as illnesses that are treated at home, in order to capture the true burden of illness in these communities.

Background A wide range of childhood illnesses are accompanied by fever,, including malaria. Child mortality due to malaria has been attributed to poor health service delivery system and ignorance. An assessment of a mother's ability to recognize malaria in children under-five was carried out among the Bwatiye, a poorly-served minority ethnic group in north-eastern Nigeria. Methods A three-stage research design involving interviews, participatory observation and laboratory tests was used to seek information from 186 Bwatiye mothers about their illness-related experiences with childhood fevers. Results Mothers classified malaria into male (fever that persists for longer than three days) and female (fever that goes away within three days) and had a system of determining when febrile illness would not be regarded as malaria. Most often, malaria would be ignored in the first 2 days before seeking active treatment. Self-medication was the preferred option. Treatment practices and sources of help were influenced by local beliefs, the parity of the mother and previous experience with child mortality. Conclusion The need to educate mothers to suspect malaria in every case of febrile illness and take appropriate action in order to expose the underlying "evil" will be more acceptable than an insistence on replacing local knowledge with biological epidemiology of malaria. The challenge facing health workers is to identify and exploit local beliefs about aetiology in effecting management procedures among culturally different peoples, who may not accept the concept of biological epidemiology.

We evaluated the clinical significance of repeat blood cultures in persistent and recurrent fever during neutropenia in adult acute myeloid leukaemia (AML) and myelodysplastic syndrome (MDS) patients undergoing intensive chemotherapy. We retrospectively reviewed the chemotherapy cycles at our centre between January 2007 and December 2015. Blood cultures obtained within three days after initial febrile neutropenia (FN) were defined as initial blood cultures and those obtained on or after day 4 were defined as repeat blood cultures. Overall, 321 chemotherapy cycles in 89 patients were subjected to review. FN was identified in 276 (86.0%) chemotherapy cycles. In persistent FN (134 episodes), the causative pathogens were detected by repeat blood cultures in seven episodes (5.2%), including only three episodes (2.2%) of new infection. Shaking chills and high body temperature were identified as significant predictors for bloodstream infection (BSI). In recurrent FN (85 episodes), the causative pathogens were detected in seven episodes (8.2%), and all of these were new organisms. The frequency of detecting new pathogens by repeat blood cultures in recurrent FN (7/85) was higher than that in persistent FN (3/134) (p = .0491). A history of recent BSI was identified as a significant predictor for BSI in recurrent FN. The diagnostic yield of repeat blood cultures for persistent FN was low in intensive chemotherapy for AML and MDS. The frequency of repeat blood cultures for persistent FN could be reduced based on predictors. On the other hand, blood cultures were considered to be essential in cases with recurrent FN.

Little is known about psychiatric illness and utilization of end-of-life care. We hypothesized that preexisting psychiatric illness would increase hospital utilization at end of life among patients with chronic medical illness due to increased severity of illness and care fragmentation. We reviewed electronic health records to identify decedents with one or more of eight chronic medical conditions based on International Classification of Diseases-9 codes. We used International Classification of Diseases-9 codes and prescription information to identify preexisting psychiatric illness. Regression models compared hospital utilization among patients with and without psychiatric illness. Path analyses examined the effect of severity of illness and care fragmentation. Eleven percent of 16,214 patients with medical illness had preexisting psychiatric illness, which was associated with increased risk of death in nursing homes (P = 0.002) and decreased risk of death in hospitals (P < 0.001). In the last 30 days of life, psychiatric illness was associated with reduced inpatient and intensive care unit utilization but increased emergency department utilization. Path analyses confirmed an association between psychiatric illness and increased hospital utilization mediated by severity of illness and care fragmentation, but a stronger direct effect of psychiatric illness decreasing hospitalizations. Our findings differ from the increased hospital utilization for patients with psychiatric illness in circumstances other than end-of-life care. Path analyses confirmed hypothesized associations between psychiatric illness and increased utilization mediated by severity of illness and care fragmentation but identified more powerful direct effects decreasing hospital use. Further investigation should examine whether this effect represents a disparity in access to preferred care. Copyright © 2017 American Academy of Hospice and Palliative Medicine.

Although acute geriatric units have improved the outcomes of hospitalized seniors, it is uncertain as to whether hospitalist care by geriatricians outside of these units confers similar benefit. To determine whether hospitalist care by geriatricians reduces short-term mortality and readmission, and length of stay (LOS) for seniors aged 80 years and older with acute medical illnesses compared with care by other internists. Retrospective cohort study using administrative and chart review data on demographic, admission-related, and clinical information of hospital episodes. General internal medicine department of an acute-care hospital in Singapore from 2005 to 2008. Seniors aged 80 years and older with specific focus on 2 subgroups with premorbid functional impairment and acute geriatric syndromes. Hospitalist care by geriatricians compared with care by other internists. Hospital mortality, 30-day mortality or readmission, and LOS. For 1944 hospital episodes (intervention: 968, control: 976), there was a nonsignificant trend toward lower hospital mortality (15.5% vs 16.9%) but not 30-day mortality or readmission, or LOS for care by geriatricians compared with care by other internists. A marginally stronger trend toward lower hospital mortality for care by geriatricians among those with acute geriatric syndromes (20.2% vs 23.1%) was observed. Similar treatment effects were found after adjustment for demographic, admission-related, and clinical factors. For seniors aged 80 years and over with acute medical illness, hospitalist care by geriatricians did not significantly reduce short-term mortality, readmission, or LOS, compared with care by other internists. © 2014 Society of Hospital Medicine.

Patients receiving myelosuppressive chemotherapy with certain comorbidities are at increased risk of febrile neutropenia. A comprehensive evaluation of febrile neutropenia-related comorbidities across cancers is needed. This study compared comorbidity prevalence among patients with cancer who did and did not develop febrile neutropenia during the first chemotherapy cycle. This case-control study used administrative claims from adult patients with non-Hodgkin lymphoma or breast, lung, colorectal, ovarian, or gastric cancer who received chemotherapy between 2007 and 2012. Each patient who developed febrile neutropenia (case) was matched with up to four patients without febrile neutropenia (controls) by cancer type, metastasis, chemotherapy regimen, age group, and sex. For each comorbidity (identified in the year before chemotherapy began), the adjusted odds ratio (aOR) for febrile neutropenia by cancer type was evaluated using conditional logistic regression models adjusted for potential confounding factors. Of 31,331 eligible patients, 672 developed febrile neutropenia in the first chemotherapy cycle. A total of 3312 febrile neutropenia cases and matched controls were analyzed. Across tumor types, comorbidity prevalence was higher in patients who developed febrile neutropenia than in those without febrile neutropenia. Among patients with breast cancer, osteoarthritis was more prevalent in patients with febrile neutropenia (aOR, 1.85; 95% CI, 1.07 to 3.18). Among patients with non-Hodgkin lymphoma, renal disease was more prevalent in patients with febrile neutropenia (aOR, 2.25; 95% CI, 1.23 to 4.11). Patients who developed febrile neutropenia in the first chemotherapy cycle presented with comorbidities more often than otherwise similar patients who did not develop febrile neutropenia. These findings warrant further investigation and support the inclusion of comorbidities into febrile neutropenia risk models. © The Author(s) 2015.

In Georgia, most individuals reported with West Nile virus (WNV) disease have been diagnosed with West Nile neuroinvasive disease (WNND). Relatively few cases of West Nile Fever (WNF) are reported, and the burden of illness due to WNV is likely underestimated. From July through October 2003, WNV serologic testing was performed on enrolled patients>or=18 years of age with fever admitted to a large, urban hospital in Atlanta, Georgia through the emergency department (ED). Patients' history, clinical, and laboratory data were recorded. Residual blood drawn in the ED was tested to determine the presence of WNV IgG and IgM antibodies. Of 254 patients tested for WNV, four (1.6%) patients were positive for WNV IgM and IgG antibodies, and had a clinical illness compatible with WNV. None of the four positive patients were clinically suspected of having WNV infection; discharge diagnoses included pneumonia, migraine, stroke, and gout. These four patients accounted for 80% of all WNV diagnosed in this hospital, 44% of all cases in Fulton County, and 7% of all cases reported in Georgia in 2003. The occurrence of WNV disease may be substantially greater than currently reflected in disease statistics in Georgia and many other states. When indicators of WNV activity are present and patients are likely to have had intensive mosquito exposure, WNV should be considered in the differential diagnosis of seriously ill, febrile patients.

Clinical Manifestations and Outcomes of West Nile Virus Infection

Since the emergence of West Nile virus (WNV) in North America in 1999, understanding of the clinical features, spectrum of illness and eventual functional outcomes of human illness has increased tremendously. Most human infections with WNV remain clinically silent. Among those persons developing symptomatic illness, most develop a self-limited febrile illness. More severe illness with WNV (West Nile neuroinvasive disease, WNND) is manifested as meningitis, encephalitis or an acute anterior (polio) myelitis. These manifestations are generally more prevalent in older persons or those with immunosuppression. In the future, a more thorough understanding of the long-term physical, cognitive and functional outcomes of persons recovering from WNV illness will be important in understanding the overall illness burden.

Extended-duration low-molecular-weight heparin has been shown to prevent venous thromboembolism (VTE) in high-risk surgical patients. To evaluate the efficacy and safety of extended-duration enoxaparin thromboprophylaxis in acutely ill medical patients. Randomized, parallel, placebo-controlled trial. Randomization was computer-generated. Allocation was centralized. Patients, caregivers, and outcome assessors were blinded to group assignment. (ClinicalTrials.gov registration number: NCT00077753) SETTING: 370 sites in 20 countries across North and South America, Europe, and Asia. Acutely ill medical patients 40 years or older with recently reduced mobility (bed rest or sedentary without [level 1] or with [level 2] bathroom privileges). Eligibility criteria for patients with level 2 immobility were amended to include only those who had additional VTE risk factors (age >75 years, history of VTE, or active or previous cancer) after interim analyses suggested lower-than-expected VTE rates. Enoxaparin, 40 mg/d subcutaneously (2975 patients), or placebo (2988 patients), for 28 +/- 4 days after receiving open-label enoxaparin for an initial 10 +/- 4 days. Incidence of VTE up to day 28 and of major bleeding events up to 48 hours after the last study treatment dose. Extended-duration enoxaparin reduced VTE incidence compared with placebo (2.5% vs. 4%; absolute risk difference favoring enoxaparin, -1.53% [95.8% CI, -2.54% to -0.52%]). Enoxaparin increased major bleeding events (0.8% vs. 0.3%; absolute risk difference favoring placebo, 0.51% [95% CI, 0.12% to 0.89%]). The benefits of extended-duration enoxaparin seemed to be restricted to women, patients older than 75 years, and those with level 1 immobility. Estimates of efficacy and safety for the overall trial population are difficult to interpret because of the change in eligibility criteria during the trial. Use of extended-duration enoxaparin reduces VTE more than it increases major bleeding events in acutely ill medical

Enteroviruses can cause outbreaks of severe acute respiratory illness (SARI) and EV-A, -B, -C, and -D species have different pathogenic profiles and circulation patterns. We aimed to characterize and determine the prevalence of enterovirus genotypes among South African patients with respiratory illness and controls during June 2012 to July 2014. Syndromic SARI and influenza-like illness (ILI) surveillance was performed at two sentinel sites. At each site nasopharyngeal/oropharyngeal specimens were collected from SARI and ILI patients as well as controls. Specimens were tested for enterovirus by real-time PCR. Positive specimenswere further genotyped by sequencing a region of theVP1 gene. The prevalence of enterovirus was 5.8% (87/1494), 3.4% (103/3079), and 3.4% (46/1367) among SARI, ILI, and controls, respectively (SARI/controls, P=0.002 and ILI/control, P = 0.973). Among the 101/236 (42.8%) enterovirus-positive specimens that could be genotyped, we observed a high diversity of circulating enterovirus genotypes (a total of 33 genotypes) from all four human enterovirus species with high prevalence of Enterovirus-B (60.4%; 61/101) and Enterovirus-A (21.8%; 22/101) compared to Enterovirus-C (10.9%; 11/101) and Enterovirus-D (6.9%; 7/101) (P = 0.477). Of the enterovirus genotypes identified, Echovirus 30 (9.9%, 10/101), Coxsackie virus B5 (7.9%, 8/101) and Enterovirus-D68 (6.9%, 7/101) were most prevalent. There was no difference in disease severity (SARI or ILI compared to controls) between the different enterovirus species (P = 0.167).We observed a high number of enterovirus genotypes in patients with respiratory illness and in controls from South Africa with no disease association of EV species with disease severity.

Background To construct evidence-based guidelines for management of febrile illness, it is essential to identify clinical predictors for the main causes of fever, either to diagnose the disease when no laboratory test is available or to better target testing when a test is available. The objective was to investigate clinical predictors of several diseases in a cohort of febrile children attending outpatient clinics in Tanzania, whose diagnoses have been established after extensive clinical and laboratory workup. Method From April to December 2008, 1005 consecutive children aged 2 months to 10 years with temperature ≥38°C attending two outpatient clinics in Dar es Salaam were included. Demographic characteristics, symptoms and signs, comorbidities, full blood count and liver enzyme level were investigated by bi- and multi-variate analyses (Chan, et al., 2008). To evaluate accuracy of combined predictors to construct algorithms, classification and regression tree (CART) analyses were also performed. Results 62 variables were studied. Between 4 and 15 significant predictors to rule in (aLR+>1) or rule out (aLR+<1) the disease were found in the multivariate analysis for the 7 more frequent outcomes. For malaria, the strongest predictor was temperature ≥40°C (aLR+8.4, 95%CI 4.7–15), for typhoid abdominal tenderness (5.9,2.5–11), for urinary tract infection (UTI) age ≥3 years (0.20,0–0.50), for radiological pneumonia abnormal chest auscultation (4.3,2.8–6.1), for acute HHV6 infection dehydration (0.18,0–0.75), for bacterial disease (any type) chest indrawing (19,8.2–60) and for viral disease (any type) jaundice (0.28,0.16–0.41). Other clinically relevant and easy to assess predictors were also found: malaria could be ruled in by recent travel, typhoid by jaundice, radiological pneumonia by very fast breathing and UTI by fever duration of ≥4 days. The CART model for malaria included temperature, travel, jaundice and hepatomegaly (sensitivity 80

Background: Despite major advances in its prevention and treatment, febrile neutropenia remains a most concerning complication of cancer chemotherapy. Outside the oncology setting, however, only few data are currently available on febrile neutropenia related to non-chemotherapy drugs. We report here data on 76 patients with febrile neutropenia related to non-chemotherapy drugs, followed up in a referral center within a university hospital. Patients and methods: Data from 76 patients with idiosyncratic drug-induced febrile neutropenia were retrospectively reviewed. All cases were extracted from a cohort study on agranulocytosis conducted at the Strasbourg University Hospital (Strasbourg, France). Results: Mean patient age was 52.2 years old (range: 18–93) and gender ratio (F/M) 1.6, with several comorbidities present in 86.8% of patients. The most common causative drugs were: antibiotics (37.4%), antithyroid drugs (17.2%), neuroleptic and anti-epileptic agents (13.1%), non-steroidal anti-inflammatory agents and analgesics (8%), and platelet aggregation inhibitors (8%). Main clinical presentations upon hospitalization included isolated fever (30%), sore throat, acute tonsillitis and sinusitis (18.4%), documented pneumonia (18.4%), septicemia (14.5%), and septic shock (6.6%). Mean neutrophil count at nadir was 0.13 × 10(9)/L (range: 0–0.48). While in hospital, 22 patients (28.9%) worsened clinically and required intensive care unit placement. All patients were promptly treated with broad-spectrum antibiotics, and 45 (59.2%) with hematopoietic growth factors. Mean duration of hematological recovery (neutrophil count ≥1.5 × 10(9)/L) was 7.5 days (range: 2–21), which was reduced to 0.7 days (range: 2–16) (p = 0.089) with hematopoietic growth factors. Outcome was favorable in 89.5% of patients, whereas eight died. Conclusions: Like in oncology and myelosuppressive chemotherapy settings, idiosyncratic febrile neutropenia is typically serious, about 40% of

The renal histopathology of critically ill patients dying with acute kidney injury (AKI) in intensive care units of high income countries remains uncertain. Retrospective observational assessment of interobserver agreement in the reporting of renal post mortem histopathology, and the ability of pathologists blinded to the clinical context to independently identify the presence of pre-mortem AKI from digital images of histological sections from 34 critically ill patients dying in teaching hospitals in Australia and Canada. We identified a heterogeneous cohort with a median age of 65 years (interquartile range [IQR], 56.5-77), APACHE II score of 27 (IQR, 19-33), and sepsis as the most common admission diagnosis (12/34; 35%). The most common proximate causes of death were cardiovascular (19/34; 56%) and respiratory (7/34; 21%) failure. AKI was common, with 23 patients (68%) developing RIFLE-F AKI, and 21 patients (62%) receiving renal replacement therapy. Structured reporting for tubular inflammation showed excellent agreement (kappa = 1), but no other subdomain demonstrated better than moderate agreement (kappa < 0.6). Only fair agreement (55.9% of cases; kappa = 0.23) was demonstrated on the diagnosis of moderate to severe acute tubular necrosis (ATN). Pathologist A predicted RIFLE-I or worse AKI with the diagnosis of ATN, with an overall accuracy of 61.8%; pathologist B predicted AKI with an accuracy of 35.3%. Post mortem assessment of the renal histopathology in critically ill patients is neither robust nor reproducible; independent pathologists agree poorly on the diagnosis of ATN, and their structural assessment appears dissociated from ante-mortem renal function.

The neurobiology of the human febrile response.

Biddle, Chuck

Fever is a normal adaptation in response to a pyrogenic stimulus resulting in the generation of cytokines and prostaglandins. Fever differs from hyperpyrexia and hyperthermia associated with hot environs and pharmacological triggers. Typically, pyrogens are infectious organisms or their direct products (toxins). The body produces a wide array of pyrogenic cytokines such as interleukins (IL-1, IL-6), interferon, and tumor necrosis factor. Tissue trauma can trigger the febrile response, as can infectious organisms, certain medications, and blood products. The circumventricular organ system (CVOS) is neuronal tissues lying outside the blood-brain barrier that has a key role in initiating the communication sequence responsible for the synthesis of febrile prostaglandins. When pyrogenic cytokines are detected by the CVOS, prostaglandin synthesis, especially cyclooxygenase-dependent prostaglandin E2, is induced, activating the febrile response. Once the appropriate signal is received by the hypothalamus, autonomic, endocrine, and behavioral processes are activated until the hypothalamic set-point is reset downward as a consequence of a reduction in pyrogen content or antipyretic therapy, with subsequent heat loss. There is little evidence that fever facilitates recovery from disease or assists the immune system in mounting a response. Antipyretics are used commonly to decrease the distressing manifestations associated with fever.

The objectives of this study were to examine the clinical profile of critically ill patients with septic acute kidney injury (AKI) and to investigate clinical characteristics associated with the outcome of patients. Data from 582 critically ill patients were collected and retrospectively reviewed. Patients were divided into two groups: without AKI development and with AKI development. Baseline characteristics, laboratory, and other clinical data were compared between these two groups, and correlations between the characteristics and AKI development were examined. Patients with AKI development were further divided into two groups according to the survival outcome, and variables associated with the outcome were determined. AKI was developed in 54.12% (n = 315) of patients, and these patients had blood pressure, SOFA score, APACHE II score, GCS, and various blood chemistry and hematology characteristics significantly different from the patients without AKI. Demographic characteristics (e.g. age and weight) were comparable between the two groups of patients. Among the 315 patients with AKI, 136 of them died during the study period. Multivariate logistic regression analysis revealed that the outcome of patients was associated with lung infection, coagulation system dysfunction, staphylococcus aureus infection, and use of various treatments (epinephrine, norepinephrine, and the use of mechanical ventilation) after AKI development. AKI occurred in approximately half of the critically ill patients admitted to ICU. The site and type of infections, as well as the use of vasopressor agents, were associated with the outcome.

To compare baseline characteristics and those found during hospitalisation as predictors of functional decline at discharge (FDd) in elderly patients hospitalised due to acute illness. A review was made of the computerized records of patients admitted to a Geriatric Acute Unit of a tertiary hospital over a 10 year period. A record was made of demographic, clinical, functional and health-care variables. Functional decline at discharge (FDd) was defined by the difference between the previous Barthel Index (pBI) and the discharge Barthel Index (dBI). The percentage of FDd (%FDd=(pBI-dBI/pBI)×100) was calculated. The variables associated with greater %FDd in the bivariate analysis were included in multivariate logistic regression models. The predictive capacity of each model was assessed using the area under the ROC curve. The factors associated with greater %FDd were advanced age, female gender, to live in a nursing home, cognitive impairment, better baseline functional status and worse functional status at admission, number of diagnoses, and prolonged stay. The area under the ROC curve for the predictive models of %FDd was 0.638 (95% CI: 0.615-0.662) based on the previous situation, 0.756 (95% CI: 0.736-0.776) based on the situation during admission, and 0.952 (95% CI: 0.944-0.959) based on a combination of these factors. The overall assessment of patient characteristics, both during admission and baseline, may have greater value in prediction of FDd than analysis of factors separately in elderly patients hospitalised due to acute illness.

A lymph node biopsy obtained from a patient with human T-cell lymphocytotropic virus III/lymphadenopathy-associated virus (HTLV-III/LAV) antibody, presenting with an acute glandular fever-like illness, was examined by electron microscopy. Numerous pathological changes were present in the biopsy, including hypertrophy of smooth endoplasmic reticulum, intracytoplasmic rod-like inclusions within the cisternae of endoplasmic reticulum, multivesicular bodies, test-tube and ring-shaped forms, and tubulo-reticular structures. Intranuclear and intracytoplasmic viral-like particles measuring 105-120 nm in diameter and small cytoplasmic particles measuring 50-70 nm in diameter were found in some degenerating lymph node cells. These pathological findings may reflect a host cell response to various pathological and viral stimuli resulting from immune deficiency owing to infection with HTLV-III/LAV.

Febrile seizures occurring in the neonatal period, especially when prolonged, are thought to be involved in the later development of mesial temporal lobe epilepsy (mTLE) in children. The presence of an often undetected, underlying cortical malformation has also been reported to be implicated in the epileptogenesis process following febrile seizures. This paper highlights some of the various animal models of febrile seizures and of cortical malformation and portrays a two-hit model that efficiently mimics these two insults and leads to spontaneous recurrent seizures in adult rats. Potential mechanisms are further proposed to explain how these two insults may each, or together, contribute to network hyperexcitability and epileptogenesis. Finally the clinical relevance of the two-hit model is briefly discussed in light of a therapeutic and preventive approach to mTLE.

To compare how parents and physicians value potential clinical outcomes in young children who have a fever but no focus of bacterial infection. Cross-sectional study of 100 parents of well children aged 3 to 24 months, 61 parents of febrile children aged 3 to 24 months, and 56 attending staff physicians working in a children's hospital emergency department. A pretested visual analog scale was used to assess values on a 0-to-1 scale (where 0 is the value of the worst possible outcome, and 1 is the value for the best) for 22 scenarios, grouped in three categories according to severity. Based on the three or four common attributes comprising the scenarios in a given group, each respondent's value function was estimated statistically based on multiattribute utility theory. For outcomes in group 1 (rapidly resolving viral infection with one or more diagnostic tests), no significant group differences were observed. For outcomes in groups 2 (acute infections without long-term sequelae) and 3 (long-term sequelae of urinary tract infection or bacterial meningitis), parents of well children and parents of febrile children had values that were similar to each other but significantly lower than physicians' values for pneumonia with delayed diagnosis, false-positive diagnosis of urinary tract infection, viral meningitis, and unilateral hearing loss. For bacterial meningitis with or without delay, however, the reverse pattern was observed; physicians' values were lower than parents'. In arriving at their judgment for group 2 and 3 scenarios, parents gave significantly greater weight to attributes involving the pain and discomfort of diagnostic tests and to diagnostic error, whereas physicians gave significantly greater weight to attributes involving both short- and long-term morbidity and long-term worry and inconvenience. Parents were significantly more likely to be risk-seeking in the way they weighted the attributes comprising group 2 and 3 scenarios than physicians, ie, they

Complement reduction impairs the febrile response of guinea pigs to endotoxin.

Although it is generally believed that circulating exogenous pyrogens [e.g., lipopolysaccharides (LPS)] induce fever via the mediation of endogenous pyrogens (EP) such as cytokines, the first of these, tumor necrosis factor-alpha, is usually not detectable in blood until at least 30 min after intravenous administration of LPS, whereas the febrile rise begins within 15 min after its administration. Moreover, although abundant evidence indicates that circulating LPS is cleared primarily by liver macrophages [Kupffer cells (KC)], these do not secrete EP in immediate response. This would imply that other factors, presumably evoked earlier than EP, may mediate the onset of the febrile response to intravenous LPS. It is well known that blood-borne LPS very rapidly activates the intravascular complement (C) system, some components of which in turn stimulate the quick release into blood of various substances that have roles in the acute inflammatory reaction. KC contain receptors for C components and are in close contact with afferent vagal terminals in the liver; the involvement of hepatic vagal afferents in LPS-induced fever has recently been shown. In this study, we tested the hypothesis that the initiation of fever by intravenous LPS involves, sequentially, the C system and KC. To test this postulated mechanism, we measured directly the levels of prostaglandin E2 (PGE2) in the interstitial fluid of the preoptic anterior hypothalamus (POA), the presumptive site of the fever-producing controller, of conscious guinea pigs over their entire febrile course, before and after C depletion by cobra venom factor (CVF) and before and after elimination of KC by gadolinium chloride (GdCl3). CVF and GdCl3 pretreatment each individually attenuated the first of the biphasic core temperature (Tc) rises after intravenous LPS, inverted the second into a Tc fall, and greatly reduced the usual fever-associated increase in POA PGE2. We conclude, therefore, that C activation may indeed be

Dengue is an acute febrile illness caused by four mosquito-borne dengue viruses (DENV-1 to -4) that are endemic throughout the tropics. After returning from a 1-week missionary trip to Haiti in October of 2010, 5 of 28 (18%) travelers were hospitalized for dengue-like illness. All travelers were invited to submit serum specimens and complete questionnaires on pre-travel preparations, mosquito avoidance practices, and activities during travel. DENV infection was confirmed in seven (25%) travelers, including all travelers that were hospitalized. Viral sequencing revealed closest homology to a 2007 DENV-1 isolate from the Dominican Republic. Although most (88%) travelers had a pre-travel healthcare visit, only one-quarter knew that dengue is a risk in Haiti, and one-quarter regularly used insect repellent. This report confirms recent DENV transmission in Haiti. Travelers to DENV-endemic areas should receive dengue education during pre-travel health consultations, follow mosquito avoidance recommendations, and seek medical care for febrile illness during or after travel.

To describe parent preference for treatment of febrile neutropenia and the key drivers of parental decision making, structured face-to-face interviews were used to elicit parent preferences for inpatient versus outpatient management of pediatric febrile neutropenia. Parents were presented with 4 different scenarios and asked to indicate which treatment option they preferred and to describe reasons for this preference during the face-to-face interview. Comments were recorded in writing by research assistants. A consensus approach to thematic analysis was used to identify themes from the written comments of the research assistants. A total of 155 parents participated in the study. Of these, 80 (51.6%) parents identified hospital-based intravenous treatment as the most preferred treatment scenario for febrile neutropenia. The major themes identified included convenience/disruptiveness, physical health, emotional well-being, and modifiers of parental decision making. Most parents preferred hospital-based treatment for febrile neutropenia. An understanding of issues that influence parental decision making may assist health care workers in planning program implementation and further support families in their decision-making process.

Acute cholecystitis is a common diagnosis. However, the heterogeneity of presentation makes it difficult to standardize management. Although surgery is the mainstay of treatment, critically ill patients have been managed via percutaneous cholecystostomy. However, the role of percutaneous cholecystostomy in the management of such patients has not been clearly established. This systematic review will compare the outcomes of critically ill patients with acute cholecystitis managed with percutaneous cholecystostomy to those of similar patients managed with cholecystectomy. Systematic searches will be conducted across relevant health databases including the Cochrane Library, Cumulative Index of Nursing and Allied Health Literature (CINAHL), MEDLINE, Embase, and Scopus using the following keywords: (acute cholecystitis OR severe cholecystitis OR cholecystitis) AND (cholecystectomy OR laparoscopic cholecystectomy OR open cholecystectomy) AND (Cholecystostomy OR percutaneous cholecystectomy OR gallbladder drain OR gallbladder tube OR transhepatic gallbladder drain OR transhepatic gallbladder tube OR cholecystostomy tube). The reference lists of eligible articles will be hand searched. Articles from 2000-2014 will be identified using the key terms "acute cholecystitis, cholecystectomy, and percutaneous cholecystostomy". Studies including both interventions will be included. Relevant data will be extracted from eligible studies using a specially designed data extraction sheet. The Newcastle-Ottawa scale will be used to assess the quality of non-randomized studies. Central tendencies will be reported in terms of means and standard deviations where necessary, and risk ratios will be calculated where possible. All calculations will be performed with a 95 % confidence interval. Furthermore, the Fisher's exact test will be used for the calculation of significance, which will be set at p < 0.05. Pooled estimates will be presented after consideration of both clinical and

The aim of the study was to explore the association of dementia with in-hospital death in acutely ill medical patients. Thirty-four internal medicine and 4 geriatric wards in Italy participated in the Registro Politerapie SIMI-REPOSI-study during 2008. One thousand three hundred and thirty two in-patients aged 65 years or older were enrolled. Logistic regression models were used to evaluate the association of dementia with in-hospital death. Socio-demographic characteristics, morbidity (single diseases and the Charlson Index), number of drugs, and adverse clinical events during hospitalization were considered as potential confounders. One hundred and seventeen participants were diagnosed as being affected by dementia. Patients with dementia were more likely to be women, older, to have cerebrovascular diseases, pneumonia, and a higher number of adverse clinical events during hospitalization. The percentage of patients affected by dementia who died during hospitalization was higher than that of patients without dementia (9.4 versus 4.9%). After multiadjustment, the diagnosis of dementia was associated with in-hospital death (OR = 2.1; 95% CI = 1.0-4.5). Having dementia and at least one adverse clinical event during hospitalization showed an additive effect on in-hospital mortality (OR = 20.7; 95% CI = 6.9-61.9). Acutely ill elderly patients affected by dementia are more likely to die shortly after hospital admission. Having dementia and adverse clinical events during hospital stay increases the risk of death. Copyright © 2010 John Wiley & Sons, Ltd.

Objective To review the available knowledge on epidemiology and diagnoses of acute infections in children aged 2 to 59 months in primary care setting and develop an electronic algorithm for the Integrated Management of Childhood Illness to reach optimal clinical outcome and rational use of medicines. Methods A structured literature review in Medline, Embase and the Cochrane Database of Systematic Review (CDRS) looked for available estimations of diseases prevalence in outpatients aged 2-59 months, and for available evidence on i) accuracy of clinical predictors, and ii) performance of point-of-care tests for targeted diseases. A new algorithm for the management of childhood illness (ALMANACH) was designed based on evidence retrieved and results of a study on etiologies of fever in Tanzanian children outpatients. Findings The major changes in ALMANACH compared to IMCI (2008 version) are the following: i) assessment of 10 danger signs, ii) classification of non-severe children into febrile and non-febrile illness, the latter receiving no antibiotics, iii) classification of pneumonia based on a respiratory rate threshold of 50 assessed twice for febrile children 12-59 months; iv) malaria rapid diagnostic test performed for all febrile children. In the absence of identified source of fever at the end of the assessment, v) urine dipstick performed for febrile children <2years to consider urinary tract infection, vi) classification of ‘possible typhoid’ for febrile children >2 years with abdominal tenderness; and lastly vii) classification of ‘likely viral infection’ in case of negative results. Conclusion This smartphone-run algorithm based on new evidence and two point-of-care tests should improve the quality of care of <5 year children and lead to more rational use of antimicrobials.

Acrolein is an aquatic herbicide used in the western United States to prevent impaired water flow in irrigation canals. Despite its toxicity, few cases of acrolein-related illness have been reported in the literature. On August 15, 2012, an irrigation district notified the Washington State Department of Labor & Industries (L&I) of acrolein-related illness in one of its pesticide applicators. L&I inspected the site and interviewed the exposed worker, coworkers, and employer. The Washington State Department of Health assisted by obtaining medical records, interviewing the patient and hospital staff, and reviewing information obtained from L&I. To look for additional cases, CDC reviewed data from the SENSOR-Pesticides program* and the California Department of Pesticide Regulation for 1993-2009, the most recent years of data availability, and identified seven additional cases of acute acrolein-related illness.

Increased Nasopharyngeal Density and Concurrent Carriage of Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis Are Associated with Pneumonia in Febrile Children

2016-01-01

Background We assessed nasopharyngeal (NP) carriage of five pathogens in febrile children with and without acute respiratory infection (ARI) of the upper (URTI) or lower tract, attending health facilities in Tanzania. Methods NP swabs collected from children (N = 960) aged 2 months to 10 years, and with a temperature ≥38°C, were utilized to quantify bacterial density of S. pneumoniae (Sp), H. influenzae (Hi), M. catarrhalis (Mc), S. aureus (Sa), and N. meningitidis (Nm). We determined associations between presence of individual species, densities, or concurrent carriage of all species combination with respiratory diseases including clinical pneumonia, pneumonia with normal chest radiography (CXR) and endpoint pneumonia. Results Individual carriage, and NP density, of Sp, Hi, or Mc, but not Sa, or Nm, was significantly associated with febrile ARI and clinical pneumonia when compared to febrile non-ARI episodes. Density was also significantly increased in severe pneumonia when compared to mild URTI (Sp, p<0.002; Hi p<0.001; Mc, p = 0.014). Accordingly, concurrent carriage of Sp+, Hi+, and Mc+, in the absence of Sa- and Nm-, was significantly more prevalent in children with ARI (p = 0.03), or clinical pneumonia (p<0.001) than non-ARI, and in children with clinical pneumonia (p = 0.0007) than URTI. Furthermore, Sp+, Hi+, and Mc+ differentiated children with pneumonia with normal CXR, or endpoint pneumonia, from those with URTI, and non-ARI cases. Conclusions Concurrent NP carriage of Sp, Hi, and Mc was a predictor of clinical pneumonia and identified children with pneumonia with normal CXR and endpoint pneumonia from those with febrile URTI, or non-ARI episodes.

Monotherapy has tended to replace the combination therapy in emprical treatment of febrile neutropenia. There is no reported trial which compares the efficacy of cefoperazone-sulbactam (CS) and piperacillin-tazobactam (PIP/TAZO) monotherapies in the treatment of febrile neutropenia. In this prospective randomized study, we aimed to compare the safety and efficacy of CS versus PIP/TAZO as empirical monotherapies in febrile neutropenic children with cancer. The study included febrile, neutropenic children hospitalized at our center for cancer. They were randomly selected to receive CS 100 mg/kg/day or PIP/TAZO 360 mg/kg/day. Duration of fever and neutropenia, absolute neutrophil count, modification, and success rate were compared between the two groups. Resolution of fever without antibiotic change was defined as success and resolution of fever with antibiotic change or death of a patient was defined as failure. Modification was defined as changing the empirical antimicrobial agent during a febrile episode. One hundred and two febrile neutropenic episodes were documented in 55 patients with a median age of 4 years. In 50 episodes CS and in 52 episodes PIP/TAZO was used. Duration of fever and neutropenia, neutrophil count, age, sex, and primary disease were not different between two groups. Success rates in the CS and PIP/TAZO groups were respectively 56 and 62% (P > 0.05). Modification rate between two groups showed no significant difference (P > 0.05). No serious adverse effect occurred in either of the groups. CS and PIP/TAZO monotherapy are both safe and effective in the initial treatment of febrile neutropenia in children with cancer.

In October 2009, two–3 months after an outbreak of a febrile disease with joint pain on the eastern coast of Madagascar, we assessed serologic markers for chikungunya virus (CHIKV), dengue virus (DENV), and Rift Valley fever virus (RVFV) in 1,244 pregnant women at 6 locations. In 2 eastern coast towns, IgG seroprevalence against CHIKV was 45% and 23%; IgM seroprevalence was 28% and 5%. IgG seroprevalence against DENV was 17% and 11%. No anti-DENV IgM was detected. At 4 locations, 450–1,300 m high, IgG seroprevalence against CHIKV was 0%–3%, suggesting CHIKV had not spread to higher inland-altitudes. Four women had IgG against RVFV, probably antibodies from a 2008 epidemic. Most (78%) women from coastal locations with CHIKV-specific IgG reported joint pain and stiffness; 21% reported no symptoms. CHIKV infection was significantly associated with high bodyweight. The outbreak was an isolated CHIKV epidemic without relevant DENV co-transmission. PMID:23092548

Benefits of mobile phone deployment for children <5 in low-resource settings remain unproven. The target population of the current demonstration study in Bushenyi District, Uganda, presented with acute fever, pneumonia, or diarrhoea and were treated by community health workers (CHWs) providing integrated community case management (iCCM). An observational study was conducted in five parishes (47 villages) served by CHWs well versed in iCCM with supplemental training in mobile phone use. Impact was assessed by quantitative measures and qualitative evaluation through household surveys, focus group discussions, and key informant interviews. CHWs in targeted sites improved child healthcare through mobile phone use coupled with iCCM. Of acutely ill children, 92.6% were correctly managed. Significant improvements in clinical outcomes compared to those obtained by CHWs with enhanced iCCM training alone were unproven in this limited demonstration. Nonetheless, qualitative evaluation showed gains in treatment planning, supply management, and logistical efficiency. Provider confidence and communications were enhanced as was ease and accuracy of record keeping. Mobile phones appear synergistic with iCCM to bolster basic supportive care for acutely ill children provided by CHWs. The full impact of expanded mobile phone deployment warrants further evaluation prior to scaling up in low-resource settings.

In this study we sought to determine the contribution of microbial translocation to febrile episodes with no attributable microbiological cause (Fever of Unknown Origin, FUO) in an adult febrile neutropaenic cohort. Endotoxin concentrations were measured with the chromogenic Limulus Amoebocyte Assay and used as a direct measure of bacterial products whilst soluble CD14 (sCD14), measured with ELISA was selected as an indicator of the early host response to endotoxins. Endotoxin concentrations in this cohort were generally elevated but did not differ with the presentation of fever. Further stratification of the febrile episodes based on the microbiological findings revealed significantly (p = 0.0077) elevated endotoxin concentrations in FUO episodes compared with episodes with documented bacterial and viral findings. sCD14 concentrations were however, elevated in febrile episodes (p = 0.0066) and no association was observed between sCD14 concentration and microbiological findings. However, FUO episodes and episodes with Gram-negative bacteraemia were associated with higher median sCD14 concentrations than episodes with Gram-positive bacteraemia (p = 0.030). In conclusion, our findings suggest that in the absence of microbiological findings, microbial translocation could contribute to febrile episodes in an adult neutropaenic cohort. We further observed an association between prophylactic antibiotic use and increased plasma endotoxin concentrations (p = 0.0212).

Evidence for the beneficial effect of therapeutic burst-suppression coma in pediatric patients with febrile refractory status epilepticus is limited, and the clinical outcomes of this treatment strategy are largely unknown. Therefore, the aim of this study was to explore the outcomes of therapeutic burst-suppression coma in a series of children with febrile refractory status epilepticus. We retrospectively reviewed consecutive pediatric patients with febrile refractory status epilepticus admitted to our pediatric intensive care unit between January 2000 and December 2013. The clinical characteristics were analyzed. Thirty-five patients (23 boys; age range: 1-18years) were enrolled, of whom 28 (80%) developed super-refractory status epilepticus. All of the patients received the continuous administration of intravenous antiepileptic drugs for febrile refractory status epilepticus, and 26 (74.3%) achieved therapeutic burst-suppression coma. All of the patients received mechanical ventilatory support, and 26 (74.3%) received inotropic agents. Eight (22.9%) patients died within 1month. The neurologically functional outcomes at 6months were good in six (27.3%) of the 22 survivors, of whom two returned to clinical baseline. The patients with therapeutic burst-suppression coma were significantly associated with hemodynamic support than the patients with electrographic seizures control (p=0.03), and had a trend of higher 1-month mortality rate, worse 6months outcomes, and a longer duration of hospitalization. Our results suggest that therapeutic burst-suppression coma to treat febrile refractory status epilepticus may lead to an increased risk of hemodynamic instability and a trend of worse outcomes.

Febrile neutropenia is an important cause of fever in the cancer patient. When he/she is undergoing chemotherapy, the priority is to exclude that complication because it requires rapid administration of empiric broad-spectrum antibiotics. We have studied the rate and characteristics of febrile neutropenia in cancer patients consulting in a emergency department. We have conducted a retrospective study in the emergency department of a cancer hospital over the year 2008. Every patient with cancer and fever > or = 38 degrees C was included. Over 2.130 consultations, 408 were selected (313 patients) including 21.6% (88) for febrile neutropenia. A focal symptom or physical sign was present in the majority of the cases. 88% were assessed as low risk for severe complications and about half of them received oral antibiotics. There were only a few patients with a nude fever for which it was difficult to make a hypothetical diagnosis in order to administer a probabilistic treatment. The majority of the consultations lead to hospital admission. Over the 80 hospitalisations, 6 deaths occurred. There was no death among the patients who remained ambulatory. In conclusion, our study shows that febrile neutropenia is frequent in ambulatory cancer patients presenting with fever and that in the majority of the cases, it is associated with a low risk. In such a situation, ambulatory management is more and more often considered or, at least, a rapid discharge after a short admission in case of low risk febrile neutropenia. In that context, the role of the general practioner has to be emphasised and to facilitate the outpatient management, we propose an algorithm that requires validation.

Over 13 weeks during two periods in 1978 the diagnostic rate for acute otitis media was monitored among febrile children in the emergency room of a large children's hospital. Temporal variation in diagnostic rates by physicians was largely attributable to differences among individual providers and independent of level of training. (Author/MLW)

A dengue fever surveillance study was conducted at three medical facilities located in the low-income district of San Javier in Medellin, Colombia. During March 2008 to 2009, 781 patients with fever regardless of chief complaint were recruited for acute dengue virus infection testing. Of the 781 tested, 73 (9.3%) were positive for dengue infection. Serotypes DENV-2 (77%) and -3 (23%) were detected by PCR. One patient met the diagnostic criteria for dengue hemorrhagic fever. Only 3 out of 73 (4.1%) febrile subjects testing positive for dengue infection were diagnosed with dengue fever by the treating physician. This study confirms dengue virus as an important cause of acute febrile illness in Medellin, Colombia, but it is difficult to diagnose without dengue diagnostic testing. PMID:24987421

Summary Purpose Neuroimaging studies suggest a history of febrile seizures, and depression, are associated with hippocampal volume reductions in patients with temporal lobe epilepsy (TLE). Methods We used radial atrophy mapping (RAM), a three-dimensional (3D) surface modeling tool, to measure hippocampal atrophy in 40 patients with unilateral TLE, with or without a history of febrile seizures and symptoms of depression. Multiple linear regression was used to single out the effects of covariates on local atrophy. Key Findings Subjects with a history of febrile seizures (n = 15) had atrophy in regions corresponding to the CA1 and CA3 subfields of the hippocampus contralateral to seizure focus (CHC) compared to those without a history of febrile seizures (n = 25). Subjects with Beck Depression Inventory II (BDI-II) score ≥14 (n = 11) had atrophy in the superoanterior portion of the CHC compared to subjects with BDI-II <14 (n = 29). Significance Contralateral hippocampal atrophy in TLE may be related to febrile seizures or depression. PMID:21269286

Fever of unclear origin is a clinical challenge in medical practice. Infectious diseases, neoplasms, and collagen vascular illnesses are its main causes in adults and children. Acute splenic sequestration crises, a known potentially fatal complication of sickle cell disease and sickle beta-thalassemia, are uncommon in beta-heterozygosis. We describe a case of prolonged recurrent episodes of fever with spontaneous resolution, commencing at age 10 in a 15-year-old boy with a history of hypochromic microcytic anemia attributed to a thalassemic trait. He was admitted twice to our university hospital for continuous-remittent fever with a pruritic, macular evanescent Still's skin rash, severe splenomegaly, leucopenia, thrombocytopenia, and sudden aggravation of anemia. Infectious, rheumatologic, autoimmune, and hematologic illnesses were excluded. A genetic-based study revealed heterozygosis of the beta-globin gene for a A>C (Thr>Pro) substitution at position 87 called Hemoglobin Valletta (alpha 2 beta 2 87 PRO) with a C>G transition in homozygosis in beta-globin intronic polymorphism intervening sequence 2 at nucleotide 745. After a follow-up period of 1 year without treatment, the young patient remains apyretic and in good general clinical health with persistent microcythemia and hepatosplenomegaly. Acute splenic sequestration crisis and related cytopenia may be an unusual complication of fever of unclear origin in a beta-thalassemic carrier of a Hemoglobin Valletta mutation and polymorphism in homozygosis of intervening sequence 2 at nucleotide 745. This hemoglobinopathy may predispose to a clinical phenotype of minor or intermediate thalassemia and, during a febrile illness, to hemoglobin instability and splenic sequestration.

To develop the comprehensive prediction model of acute gastrointestinal injury (AGI) grades of critically ill patients. From April 2015 to November 2015, the binary channel gastrointestinal sounds (GIS) monitor system which has been developed and verified by the research group was used to gather and analyze the GIS of 60 consecutive critically ill patients who were admitted in Critical Care Medicine of Chinese PLA General Hospital. Also, the AGI grades (Grande I(-IIII(, the higher the level, the heavier the gastrointestinal dysfunction) were evaluated. Meanwhile, the clinical data and physiological and biochemical indexes of included patients were collected and recorded daily, including illness severity score (APACHE II( score, consisting of the acute physiology score, age grade and chronic health evaluation), sequential organ failure assessment (SOFA score, including respiration, coagulation, liver, cardioascular, central nervous system and kidney) and Glasgow coma scale (GCS); body mass index, blood lactate and glucose, and treatment details (including mechanical ventilation, sedatives, vasoactive drugs, enteral nutrition, etc.) Then principal component analysis was performed on the significantly correlated GIS (five indexes of gastrointestinal sounds were found to be negatively correlated with AGI grades, which included the number, percentage of time, mean power, maximum power and maximum time of GIS wave from the channel located at the stomach) and clinical factors after standardization. The top 5 post-normalized main components were selected for back-propagation (BP) neural network training, to establish comprehensive AGI grades models of critically ill patients based on the neural network model. The 60 patients aged 19 to 98 (mean 54.6) years and included 42 males (70.0%). There were 22 cases of multiple fractures, 15 cases of severe infection, 7 cases of cervical vertebral fracture, 7 cases of aortic repair, 5 cases of post-toxicosis and 4 cases of cerebral

Mapping chronic illness in the age of globalization: reclaiming the good for the chronically ill.

Until recently, infectious diseases were the main cause of death worldwide. New medical discoveries and the evolution of public health improved life expectancy and the ability to survive acute threats, thus changing the course of diseases from acute to chronic. Today, chronic illness is the most important health concern worldwide. Chronic illness increases existing poverty and pushes other people into it. As nurses, members of the healthcare system and members of this world, we cannot forget that our response toward globalization and chronic disease has to be centered in leadership through reorienting local and national healthcare systems. All actions must be grounded in the ethical treatment of the ill; we cannot close our eyes in hospitals or communities to what is happening now worldwide because our responsibility is to promote health, prevent disease, and care for human beings.

Data about the prevalence of sarcopenia among hospitalized patients is lacking and it is unclear whether the diagnostic criteria commonly used in community-dwellers is applicable in acutely ill subjects. The aims of this report are: (i) to assess the prevalence of sarcopenia among hospitalized patients; (ii) to assess whether the European Working Group on Sarcopenia in Older People (EWGSOP) criteria are applicable in an acute care setting; and (iii) to assess the mortality rate at 3 months. 103 patients admitted to the Acute Geriatric Clinic were enrolled. Inclusion criteria were: age ≥65 years and malnutrition or risk of malnutrition, according to the Mini Nutritional Assessment Short Form. Sarcopenia was diagnosed using the EWGSOP criteria by means of bioimpedance analysis, handgrip strength and gait speed, within 72 h of admission. Information on deaths was obtained by telephone interview at 3 months following discharge. Sarcopenia was diagnosed in 22 patients (21.4%). Twenty-three patients (22.3%) were not able to perform the gait speed and/or the handgrip strength because bedridden or requiring intensive treatments. In this group, a definite diagnosis of sarcopenia was not possible, lacking at least one EWGSOP criteria. Eleven (10.7%) patients died within the 3 months post-discharge period. Kaplan-Meier survival curves showed that sarcopenic patients died significantly more frequently than others (log-rank p ≤ 0.001). In a population of hospitalized elderly malnourished or at risk of malnutrition, sarcopenia is highly prevalent and associated with an increased risk to die in the short-term. Furthermore, the EWGSOP criteria cannot be satisfactorily applied in a relevant proportion of patients. Copyright © 2014 Elsevier Ltd and European Society for Clinical Nutrition and Metabolism.

Rocky Mountain spotted fever (RMSF) is an emerging public health issue on some American Indian reservations in Arizona. RMSF causes an acute febrile illness that, if untreated, can cause severe illness, permanent sequelae requiring lifelong medical support, and death. We describe costs associated with medical care, loss of productivity, and death among cases of RMSF on two American Indian reservations (estimated population 20,000) between 2002 and 2011. Acute medical costs totaled more than $1.3 million. This study further estimated $181,100 in acute productivity lost due to illness, and $11.6 million in lifetime productivity lost from premature death. Aggregate costs of RMSF cases in Arizona 2002–2011 amounted to $13.2 million. We believe this to be a significant underestimate of the cost of the epidemic, but it underlines the severity of the disease and need for a more comprehensive study. PMID:26033020

Acute Pesticide-Related Illness Among Farmworkers: Barriers to Reporting to Public Health Authorities

Prado, Joanne Bonnar; Mulay, Prakash R.; Kasner, Edward J.; Bojes, Heidi K.; Calvert, Geoffrey M.

2018-01-01

Farmworkers are at high risk of acute occupational pesticide-related illness (AOPI) and AOPI surveillance is vital to preventing these illnesses. Data on such illnesses are collected and analyzed to identify high-risk groups, high-risk pesticides, and root causes. Interventions to address these risks and root causes include farmworker outreach, education, and regulation. Unfortunately, it is well known that AOPI is underreported, meaning that the true burden of this condition remains unknown. This article reviews the barriers to reporting of farmworker AOPI to public health authorities and provides some practical solutions. Information is presented using the social-ecological model spheres of influence. Factors that contribute to farmworker AOPI underreporting include fear of job loss or deportation, limited English proficiency (LEP), limited access to health care, lack of clinician recognition of AOPI, farmworker ineligibility for workers’ compensation (WC) benefits in many states, insufficient resources to conduct AOPI surveillance, and constraints in coordinating AOPI investigations across state agencies. Solutions to address these barriers include: emphasizing that employers encourage farmworkers to report safety concerns; raising farmworker awareness of federally qualified health centers (FQHCs) and increasing the availability of these clinics; improving environmental toxicology training to health-care students and professionals; encouraging government agencies to investigate pesticide complaints and provide easy-to-read reports of investigation findings; fostering public health reporting from electronic medical records, poison control centers (PCCs), and WC; expanding and strengthening AOPI state-based surveillance programs; and developing interagency agreements to outline the roles and responsibilities of each state agency involved with pesticide safety.

Acute infection is the most common presentation of children in primary care with only few having a serious infection (eg, sepsis, meningitis, pneumonia). To avoid complications or death, early recognition and adequate referral are essential. Clinical prediction rules have the potential to improve diagnostic decision-making for rare but serious conditions. In this study, we aimed to validate a recently developed decision tree in a new but similar population. Diagnostic accuracy study validating a clinical prediction rule. Acutely ill children presenting to ambulatory care in Flanders, Belgium, consisting of general practice and paediatric assessment in outpatient clinics or the emergency department. Physicians were asked to score the decision tree in every child. The outcome of interest was hospital admission for at least 24 h with a serious infection within 5 days after initial presentation. We report the diagnostic accuracy of the decision tree in sensitivity, specificity, likelihood ratios and predictive values. In total, 8962 acute illness episodes were included, of which 283 lead to admission to hospital with a serious infection. Sensitivity of the decision tree was 100% (95% CI 71.5% to 100%) at a specificity of 83.6% (95% CI 82.3% to 84.9%) in the general practitioner setting with 17% of children testing positive. In the paediatric outpatient and emergency department setting, sensitivities were below 92%, with specificities below 44.8%. In an independent validation cohort, this clinical prediction rule has shown to be extremely sensitive to identify children at risk of hospital admission for a serious infection in general practice, making it suitable for ruling out.

We evaluated risk factors for neutropenic fever and febrile prolonged neutropenia during vincristine-including chemotherapy to treat HIV-related lymphoma to investigate whether protease inhibitor (PI) treatment is associated with infectious complications due to drug interactions with chemotherapeutic agents. We included all HIV patients who received chemotherapy including vincristine for lymphoma at a single referral center in 1999-2010. Neutropenic fever was defined as absolute neutrophil count < 500 cells/µL with body temperature over 38℃; and prolonged neutropenia was defined if it persisted over 7 days. CODOX-M/IVAC and Stanford regimens were considered high-risk regimens for prolonged neutropenia. We analyzed 48 cycles of chemotherapy in 17 HIV patients with lymphoma. There were 22 neutropenic fever and 12 febrile prolonged neutropenia events. In multivariate analysis, neutropenic fever was associated with old age and low CD4 cell count, but not with PI use or ritonavir-boosted PI use. Low CD4 cell count and high-risk regimens were associated with febrile prolonged neutropenia. Neutropenic fever and febrile prolonged neutropenia is associated with old age, low CD4 cell count, and high-risk regimens, but not PI use, in HIV patients undergoing chemotherapy including vincristine for lymphoma.

The most recent Confidential Enquiry into Maternal Deaths (CMACE, 2011) identified human errors, specifically those of midwives and obstetricians/doctors as a fundamental component in contributing to maternal death in the U.K. This paper discusses these findings and outlines a project to provide training in Maternal-Acute Illness Management (M-AIM) to final year student midwives. Contents of the program are designed to educate and simulate AIM skills and increase confidence and clinical ability in early recognition, management and referral of the acutely ill woman. An outline of the Maternal-AIM program delivered at the University of Salford (Greater Manchester, UK) is presented to illustrate how this particular institution has responded to a perceived need voiced by local midwifery leaders. It is proposed that developing this area of expertise in the education system will better prepare student midwives for contemporary midwifery practice. Crown Copyright © 2014.

The social practice of rescue: the safety implications of acute illness trajectories and patient categorisation in medical and maternity settings.

PubMed

Mackintosh, Nicola; Sandall, Jane

2016-02-01

The normative position in acute hospital care when a patient is seriously ill is to resuscitate and rescue. However, a number of UK and international reports have highlighted problems with the lack of timely recognition, treatment and referral of patients whose condition is deteriorating while being cared for on hospital wards. This article explores the social practice of rescue, and the structural and cultural influences that guide the categorisation and ordering of acutely ill patients in different hospital settings. We draw on Strauss et al.'s notion of the patient trajectory and link this with the impact of categorisation practices, thus extending insights beyond those gained from emergency department triage to care management processes further downstream on the hospital ward. Using ethnographic data collected from medical wards and maternity care settings in two UK inner city hospitals, we explore how differences in population, cultural norms, categorisation work and trajectories of clinical deterioration interlink and influence patient safety. An analysis of the variation in findings between care settings and patient groups enables us to consider socio-political influences and the specifics of how staff manage trade-offs linked to the enactment of core values such as safety and equity in practice. © 2015 The Authors.

To provide a current review of the clinical characteristics, predictors and outcomes in critically ill patients presenting to the ED with acute pancreatitis and subsequently admitted to an intensive care unit (ICU) of a tertiary referral centre in Australia. A retrospective single-centre study of adult patients admitted with pancreatitis. Severe acute pancreatitis defined by Bedside Index of Severity in Acute Pancreatitis (BISAP) score ≥2. Eighty-seven patients fulfilled criteria for inclusion during the study period, representing 0.9% of all ICU admissions. The median age of patients was 54. Survival was independent of patients' age, sex, aetiology and comorbidities. Mortality was 30.8% for both inpatient referrals to the ICU and for direct referrals via the ED. Higher mortality was identified among patients requiring mechanical ventilation (74.2 vs 24.6% in survivors; P < 0.0001), vasopressor support (85.7 vs 33.8% in survivors; P < 0.0001) or renal replacement therapy (60 vs 16.9% in survivors; P < 0.002). BISAP score surpasses Ranson's and Acute Physiological and Chronic Health Examination (APACHE) II scores in discriminating between survivors and non-survivors among unselected patients with acute pancreatitis admitted to ICU, whereas APACHE II discriminates better in the cohort admitted from ED. Severe acute pancreatitis is associated with high mortality. Aetiology and comorbidity did not predict adverse outcomes in this population. BISAP score is non-inferior to APACHE II score as a prognostic tool in critically ill patients with acute pancreatitis and could be used to triage admission. Evidence of persistent organ dysfunction and requirements for organ support reliably identify patients at high-risk of death. © 2017 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

PROTOCOL FOR REDUCING TIME TO ANTIBIOTICS IN FEBRILE NEONATES PRESENTING TO THE EMERGENCY DEPARTMENT: A QUALITY IMPROVEMENT INITIATIVE

PubMed Central

Boutin, A

2017-01-01

Abstract BACKGROUND: Febrile neonates are at high risk of morbidity and mortality from infectious causes. This risk further increases if antibiotics are not received in a timely manner. Current guidelines recommend early initiation (less than 1 hour) of antibiotics for patients with severe sepsis. Time-to-antibiotic administration (TAA) should also be targeted as a quality-of-care (QOC) measure for febrile neonates. A previous evaluation showed that most of these patients were not receiving antibiotics in the first hour at our emergency department (ED). OBJECTIVES: We evaluated whether a simple quality improvement protocol would improve the proportion of febrile neonates receiving antibiotics within 60 minutes of arrival to the ED. DESIGN/METHODS: This was a pre-post intervention study conducted in the ED of an academic pediatric tertiary care hospital with an annual volume of approximately 83,000 patients in 2014-2016. Participants were a random sample of all children younger than 28 days old visiting the ED for a febrile illness. The new protocol, which consisted for the nurses, after triage, to place the patients directly in the resuscitation room for immediate assessment by a physician, was implemented in February 2016. Previously, these children were triaged level 2 on the Canadian Triage and Acuity Scale (CTAS), flagged and placed in a regular examination room waiting for the physician assessment. With the new protocol, IV access, blood culture, urine analysis and culture were immediately obtained by the nurse in charge with the concomitant assessment by the attending physician. Forty charts prior to and 50 charts after protocol initiation were reviewed by an archivist using a standardized form between 2014-2015 and 2016, respectively. The primary outcome was TAA. This was defined as the time from initial ED registration to the beginning of antibiotics infusion. As a secondary outcome, all cases were reviewed individually to determine barriers to rapid

In this study, we evaluated the performance of a rapid test, the SD BIOLINE Dengue Duo (SD BDD) kit, with a panel of serum samples from 310 Mexican patients with diagnosis of dengue infection previously confirmed by reference enzyme-linked immunosorbent assay tests. Eighty-seven negative samples from other febrile illnesses were included as controls. The SD BDD showed an overall sensitivity of 90.65% and specificity of 89.66%. No statistically significant differences were found in the sensitivity of the SD BDD kit compared between primary or secondary infections (87.05% versus 93.57%, respectively, P = 0.0761) and dengue fever or dengue hemorrhagic fever cases (90.77% versus 89.74%, respectively, P = 0.7716). However, a higher sensitivity in the acute phase of dengue infection was found compared with the convalescent phase (93.03% versus 81.82%, respectively, P = 0.0089). These results indicate that the SD BDD kit is a useful tool to diagnose dengue infections, both in primary or secondary infections and mainly during the acute phase. Copyright © 2014 Elsevier Inc.

Introduction Query (Q) fever is an important zoonosis and a cause of concern for humans, due to the potential bioterrorism threat posed by the causative agent, Coxiella burnetii. Because of the danger of contracting the illness, isolation attempts are seldom made. Serological and molecular diagnostic tests are the main option. Aim To study the prevalence of acute Q fever in Puducherry and surrounding districts of Tamil Nadu, India, employing a new commercial Real-Time Polymerase Chain Reaction (RT-PCR) kit and confirming it by the gold standard Immunofluorescence Assay (IFA). Materials and Methods Acute phase blood samples from 72 consecutive febrile patients and 24 healthy individuals were included in this prospective study. DNA was extracted from the buffy coats and preserved at -80°C. Detection of C. burnetii was carried out employing a commercial Real-Time PCR kit. Serum samples were tested for IgM (Phase I+II) and IgG (Phase I+II) by QM-120 and QG-120, Coxiella burnetii IFA Fuller Laboratories, California, USA. Sensitivity, Specificity, Positive Predictive Value (PPV) and Negative Predictive Value (NPV) were calculated keeping IFA as the reference. Results Presumptive diagnosis of acute Q fever was made in two febrile patients by the Genesig Easy kit (2.78%). In addition to these two PCR positive cases, one more patient was positive for both Phase II IgM and Phase II IgG antibodies by the gold standard IFA. All 24 healthy controls were negative for Q fever by both PCR and IFA. The sensitivity, specificity, NPV and PPV for Genesig Easy kit PCR were: 66.67%, 100%, 100% and 98.57 % respectively against IFA as the reference. Conclusion The true prevalence of Q fever in India and other developing countries is poorly understood, owing to the difficulties in the diagnosis of this infection. Since molecular diagnostic tests have good specificity and are mandated for confirmation of single acute samples, validation of commercial Q fever PCR kits is the need of the

Critically ill patients with severe sepsis or septic shock may need relatively high colistin daily doses for efficacy against multidrug-resistant and extensively drug-resistant gram-negative rods. However, acute kidney injury (AKI) may represent a major dose-limiting adverse effect of colistin. We sought to determine AKI occurrence and to identify factors influencing AKI risk in severely ill patients receiving colistin according to a recently proposed dosing strategy. A prospective, observational, cohort study involving patients with severe sepsis or septic shock who received colistin was performed. AKI was defined according to Acute Kidney Injury Network criteria. Colistin administration was driven by a modified pharmacokinetics-pharmacodynamics (PK/PD)-based dosing approach. Of 70 patients who received colistin at a median daily dose of 9 million IU (MIU; interquartile range, 5.87-11.1 MIU), 31 (44%) developed AKI. In univariate analysis, age, Acute Physiology and Chronic Health Evaluation (APACHE) II score, Sequential Organ Failure Assessment (SOFA), score and baseline renal impairment were significantly associated with AKI. Moreover, patients with AKI were less frequently treated with adjuvant ascorbic acid (P = .003). In multivariate analysis, independent predictors of AKI were baseline renal impairment (adjusted hazard ratio, 4.15; 95% confidence interval, 1.9-9.2; P < .001) and age (1.03; 1.0-1.05; P = .028), whereas a strong independent renal-protective role emerged for ascorbic acid (0.27; .12-.57; P < .001). In severely ill patients receiving colistin according to a PK/PD-driven dosing approach, baseline renal impairment and older age strongly predict AKI occurrence, but concomitant administration of ascorbic acid markedly reduces AKI risk, allowing safer use of colistin. © The Author 2015.

Current imaging recommendations for investigating any infantile febrile urinary tract infection (UTI) are ultrasound scan (US), micturating cystourethrogram (MCUG) and dimercaptosuccinic acid (DMSA) scan. The aim of this retrospective cohort study was to determine the need and indications for MCUG in the investigation of a first febrile infantile UTI, as doubts have been raised over its benefit. Information on 427 infants who had undergone US, MCUG and DMSA following a first febrile UTI was prospectively recorded. The infants were divided into two groups: A (354) with normal renal US and B (73) with abnormal US. DMSA findings were correlated with findings on MCUG. Main outcome measures were incidence of recurrent UTIs, change in management or intervention as a result of MCUG, and outcome at discharge. Only 21/354 (6%) infants in Group A had both scarring on DMSA and vesicoureteric reflux (VUR), predominantly low-grade on MCUG. In Group B (abnormal US), 23/73 (32%) had scarring on DMSA and vesicoureteric reflux, predominantly high grade on MCUG. Of the infants with non-scarred kidneys, 73% had dilating reflux. Successful conservative treatment was performed in 423 infants, and 4 infants in Group B required surgery. We recommend US and DMSA in all infantile febrile UTI cases. Where US is normal, MCUG should be reserved for those cases with abnormal DMSA. Where US is abnormal, MCUG should be performed irrespective of findings on DMSA scan. A randomized prospective study is necessary to evaluate this further. Copyright © 2009 Journal of Pediatric Urology Company. Published by Elsevier Ltd. All rights reserved.

This study aimed at assessing the cut-off levels for pentraxin 3 (PTX3) in predicting complications of neutropenic fever (bacteraemia, septic shock) in haematological patients. A prospective study during 2006-2009 was performed at haematology ward in Kuopio University Hospital. A patient was eligible for the study if having neutropenic fever after intensive therapy for acute myeloid leukaemia (AML) (n = 32) or non-Hodgkin lymphoma (NHL) (n = 35). Blood cultures were taken, and maximal PTX3 and C-reactive protein (CRP) were evaluated during d0 to d3 from the beginning of fever onset. The level of PTX3 was associated with both the underlying malignancy and the presence of complications, with highest level in NHL patients with complicated course of febrile neutropenia and lowest in AML patients with non-complicated course. The cut-off level of PTX3 to predict complications was ten-fold in patients with NHL (115 μg/L) in comparison with patients with AML (11.5 μg/L). In combined analysis based on separate cut-offs, PTX3 predicted complications of febrile neutropenia with sensitivity of 0.86, specificity of 0.83, positive predictive value of 0.57 and negative predictive value of 0.96.   PTX3 was superior to CRP in predicting complicated course of febrile neutropenia, but only when the effect of the underlying malignancy had been taken into account. © 2011 John Wiley & Sons A/S.

To compare the costs associated with care by two community children's nursing teams (CCNT). A case study incorporating questionnaire survey, analysis of routinely collected data and analysis of costs in the north-west England. Children with acute illness referred for CCNT care. Two CCNT provided care for 273 children during acute illness in order to reduce the number and duration of hospital admissions. Costs of CCNT, other services and costs to families. The objectives of both CCNT included shortening and avoiding hospitalisations. Most (45 (58%) in case A and 150 (77%) in case B) children were referred for infections. There were differences in the proportion of children who had been hospitalised (45 (57.7%) and 78 (40%)), the mean number of services used before referral to CCNT (1.6 and 2.2) and the staffing profile of the CCNT. There was a statistically significant difference in the overall mean cost to the NHS of CCNT care (£146 and £238, 95% CI for difference of means 7 to 184), associated with higher proportions of children having telephone-only contact (two (3%) and 46 (24%)) and children using almost twice as many other health services during care by one CCNT (means 0.27 and 0.51). Costs of CCNT care can vary widely when all health service use is taken into account. Differences in the way CCNT are integrated with the urgent care system, and the way in which CCNT care is organised, could contribute to variations in costs.

Febrile neutropenia: outline of management.

Febrile neutropenia is a common emergency encountered in children receiving chemotherapy for a malignancy. Left untreated, it can lead to serious morbidity and mortality. Febrile neutropenia is suspected in any patient on chemotherapy who presents with fever. Prompt evaluation and management by the primary contact pediatrician is essential for a successful outcome. A detailed history and physical examination is warranted to identify source of infection, although two thirds of them may not have localizing symptoms or signs. Risk stratification is valuable in categorizing the severity and guiding therapy. Initial stabilization, prompt initiation of appropriate antibiotics and adequate supportive care are the cornerstone of treatment. Knowledge of the locally prevailing bacteriological profile and antimicrobial susceptibility data is crucial for each hospital/unit to frame and periodically modify guidelines for the choice of antimicrobials. Delay in initiating antimicrobials significantly worsens the outcome. Education of the family as well as the members of the treating unit is important in this regard. Pro-active steps must be taken to reduce incidence of hospital acquired sepsis. Diagnosis and management in relevance to the emergency room is reviewed and institutional practice is shared.

An acute disease is regularly associated with inflammation, decreased food intake, and low physical activity; the consequence is loss of muscle mass. However, the restoration of muscle tissue is problematic, especially in older patients. Loss of muscle mass leads to further decrease of physical activity which leads, together with recurring disease, to the progressive muscle mass loss accompanied by loss of self-sufficiency. Early nutrition support and physical activity could reverse this situation. Therefore, the aim of this study was to determine whether an active approach based on early nutritional therapy and exercise would influence the development of sarcopenia and impaired self-sufficiency during acute illness. Two hundred patients >78 y were admitted to a hospital internal medicine department and participated in a prospective, randomized controlled study. The patients were randomized to a control group receiving standard treatment (n = 100) or to an intervention group (n = 100). The intervention consisted of nutritional supplements (600 kcal, 20 g/d protein) added to a standard diet and a simultaneous intensive rehabilitation program. The tolerance of supplements and their influence on spontaneous food intake, self-sufficiency, muscle strength, and body composition were evaluated during the study period. The patients were then regularly monitored for 1 y post-discharge. The provision of nutritional supplements together with early rehabilitation led to increased total energy and protein intake while the intake of standard hospital food was not reduced. The loss of lean body mass and a decrease in self-sufficiency were apparent at discharge from the hospital and 3 mo thereafter in the control group. Nutritional supplementation and the rehabilitation program in the study group prevented these alterations. A positive effect of nutritional intervention and exercise during the hospital stay was apparent at 6 mo post-discharge. The early nutritional intervention

Febrile neutropenia (FN) causes significant morbidity and mortality in patients receiving cytotoxic chemotherapy and can lead to reduced chemotherapy dose intensity and increased overall treatment costs. Antibiotic prophylaxis reduces the incidence of FN. Recent research and meta-analyses confirm that prophylactic fluoroquinolones decrease FN and infection-related mortality in patients with acute leukaemia and those receiving high-dose chemotherapy. Fluoroquinolone prophylaxis also lowers the incidence of FN and all-cause mortality following the first cycle of myelosuppressive chemotherapy for solid tumours. Levofloxacin has been the agent studied most thoroughly in this context. Although there is no convincing evidence that colonisation of individuals with resistant organisms due to antibiotic prophylaxis increases FN or mortality, such concerns must be taken seriously and the use of prophylaxis should be limited responsibly for patients with the greatest chance of benefit. Fluoroquinolone prophylaxis is well tolerated and cost-effective and should be offered to patients receiving chemotherapy for haematological malignancies and high-dose chemotherapy for solid tumours in which prolonged (>7 days) neutropenia is expected. It should also be considered for those receiving chemotherapy for solid tumours and lymphomas during the first cycle of chemotherapy when grade 4 neutropenia is anticipated.

Epilepsy comprises several syndromes, amongst the most common being mesial temporal lobe epilepsy with hippocampal sclerosis. Seizures in mesial temporal lobe epilepsy with hippocampal sclerosis are typically drug-resistant, and mesial temporal lobe epilepsy with hippocampal sclerosis is frequently associated with important co-morbidities, mandating the search for better understanding and treatment. The cause of mesial temporal lobe epilepsy with hippocampal sclerosis is unknown, but there is an association with childhood febrile seizures. Several rarer epilepsies featuring febrile seizures are caused by mutations in SCN1A, which encodes a brain-expressed sodium channel subunit targeted by many anti-epileptic drugs. We undertook a genome-wide association study in 1018 people with mesial temporal lobe epilepsy with hippocampal sclerosis and 7552 control subjects, with validation in an independent sample set comprising 959 people with mesial temporal lobe epilepsy with hippocampal sclerosis and 3591 control subjects. To dissect out variants related to a history of febrile seizures, we tested cases with mesial temporal lobe epilepsy with hippocampal sclerosis with (overall n = 757) and without (overall n = 803) a history of febrile seizures. Meta-analysis revealed a genome-wide significant association for mesial temporal lobe epilepsy with hippocampal sclerosis with febrile seizures at the sodium channel gene cluster on chromosome 2q24.3 [rs7587026, within an intron of the SCN1A gene, P = 3.36 × 10−9, odds ratio (A) = 1.42, 95% confidence interval: 1.26–1.59]. In a cohort of 172 individuals with febrile seizures, who did not develop epilepsy during prospective follow-up to age 13 years, and 6456 controls, no association was found for rs7587026 and febrile seizures. These findings suggest SCN1A involvement in a common epilepsy syndrome, give new direction to biological understanding of mesial temporal lobe epilepsy with hippocampal sclerosis with febrile seizures

Point-of-care C-reactive protein (CRP) testing of adults with acute respiratory infection in primary care reduces antibiotic prescribing by 22%. The acceptability and impact of CRP testing in children is unknown To determine the acceptability and impact of CRP testing in acutely ill children. Mixed methods study comprising an observational cohort with a nested randomised controlled trial and embedded qualitative study. Children presenting with an acute illness to general practice out-of-hours services; children with a temperature ≥38°C were randomised in the nested trial; parents and clinical staff were invited to the qualitative study. Informed consent rates; parental and staff views on testing. Consent to involvement in the study was obtained for 200/297 children (67.3%, 95% CI 61.7% to 72.6%); the finger-prick test might have been a contributory factor for 63 of the 97 children declining participation but it was cited as a definite factor in only 10 cases. None of the parents or staff raised concerns about the acceptability of testing, describing the pain caused as minor and transient. General practitioner views on the utility of the CRP test were inconsistent. CRP point-of-care testing in children is feasible in primary care and is likely to be acceptable. However, it will not reduce antibiotic prescribing and hospital referrals until general practitioners accept its diagnostic value in children. ISRCTN 69736109.

Temporal lobe epilepsy (TLE) is accompanied by an abnormal location of granule cells in the dentate gyrus. Using a rat model of complex febrile seizures, which are thought to be a precipitating insult of TLE later in life, we report that aberrant migration of neonatal-generated granule cells results in granule cell ectopia that persists into adulthood. Febrile seizures induced an upregulation of GABA(A) receptors (GABA(A)-Rs) in neonatally generated granule cells, and hyperactivation of excitatory GABA(A)-Rs caused a reversal in the direction of granule cell migration. This abnormal migration was prevented by RNAi-mediated knockdown of the Na(+)K(+)2Cl(-) co-transporter (NKCC1), which regulates the excitatory action of GABA. NKCC1 inhibition with bumetanide after febrile seizures rescued the granule cell ectopia, susceptibility to limbic seizures and development of epilepsy. Thus, this work identifies a previously unknown pathogenic role of excitatory GABA(A)-R signaling and highlights NKCC1 as a potential therapeutic target for preventing granule cell ectopia and the development of epilepsy after febrile seizures.

With the increasing use of adjuvant chemotherapy for treating early breast cancer, febrile neutropenia management has become crucial. Guidelines for febrile neutropenia management are mostly based on a Caucasian population survey although ethnic differences are reported in terms of adverse events. We survey the current status of febrile neutropenia and risk factors in Japanese female breast cancer patients receiving neoadjuvant and adjuvant chemotherapy regimens potential for febrile neutropenia. Subsequently, we plan to conduct a multicenter prospective cohort study involving 1000 patients with operable breast cancer. With the current state of oral antibiotics being routinely prescribed without hematology tests, we survey febrile neutropenia based on two different definitions, namely, true febrile neutropenia: ≥37.5°C and Grade 4 neutropenia, and surrogate febrile neutropenia: ≥37.5°C and oral antibiotic and antipyretic intake. The comparison of true febrile neutropenia and surrogate febrile neutropenia incidences is anticipated to provide information on the safety and feasibility of chemotherapy management without performing blood tests. © The Author 2016.

The diagnostic value of troponin in critically ill.

Voga, Gorazd

2010-01-01

Troponin T and I are sensitive and specific markers of myocardial necrosis. They are used for the routine diagnosis of acute coronary syndrome. In critically ill patients they are basic diagnostic tool for diagnosis of myocardial necrosis due to myocardial ischemia. Moreover, the increase of troponin I and T is related with adverse outcome in many subgroups of critically ill patients. The new, high sensitivity tests which have been developed recently allow earlier and more accurate diagnosis of acute coronary syndrome. The use of the new tests has not been studied in critically ill patients, but they will probably replace the old tests and will be used on the routine basis.

Managing fever and febrile symptoms in HIV: evidence-based approaches.

Holtzclaw, Barbara J

2013-01-01

Fever remains a common symptom for persons living with HIV (PLWH) despite improving overall health and survival rates. Elevated body temperatures are among the classic symptoms of primary HIV infection and are later harbingers of opportunistic infections. Therapeutic agents, including antiretrovirals, antifungals, interleukins, interferon, and blood products, can produce fever. While research shows that fever holds immunological benefits, and outdated practices to cool febrile patients create distress and energy expenditure from shivering, "fever phobia" persists. This article discusses the evolution of understanding about fever and HIV infection, its influence on caregivers and PLWH, and the existing evidence surrounding (a) physiological threats and benefits of the febrile response for PLWH, (b) goals underpinning assessment and management of fever and related febrile symptoms, and (c) development and testing of fever-management interventions. This evidence is summarized with rationale for the need to educate both public and professionals about the complexities of fever. Copyright © 2013 Association of Nurses in AIDS Care.

2014-01-01

Purpose This study sought to evaluate factors associated with hospital length of stay in cancer patients with febrile neutropenia. Methods A prospective cohort study was performed at a single tertiary referral hospital in southern Brazil from October 2009 to August 2011. All adult cancer patients with febrile neutropenia admitted to the hematology ward were evaluated. Stepwise random-effects negative binomial regression was performed to identify risk factors for prolonged length of hospital stay. Results In total, 307 cases of febrile neutropenia were evaluated. The overall median length of hospital stay was 16 days (interquartile range 18 days). According to multiple negative binomial regression analysis, hematologic neoplasms (P = 0.003), high-dose chemotherapy regimens (P<0.001), duration of neutropenia (P<0.001), and bloodstream infection involving Gram-negative multi-drug-resistant bacteria (P = 0.003) were positively associated with prolonged hospital length of stay in patients with febrile neutropenia. The condition index showed no evidence of multi-collinearity effect among the independent variables. Conclusions Hematologic neoplasms, high-dose chemotherapy regimens, prolonged periods of neutropenia, and bloodstream infection with Gram-negative multi-drug-resistant bacteria are predictors of prolonged length hospital of stay among adult cancer patients with febrile neutropenia.

To investigate the incidence, clinical and microbiological features of febrile, and risk factors during neutropenia periods in patients with hematological diseases. From October 20, 2014 to March 20, 2015, consecutive patients who had hematological diseases and developed neutropenia during hospitalization were enrolled in the prospective, multicenter and observational study. A total of 784 episodes of febrile occurred in 1 139 neutropenic patients with hematological diseases. The cumulative incidence of febrile was 81.9% at 21 days after neutropenia. Multivariate analysis suggested that central venous catheterization (P<0.001, HR=3.407, 95% CI 2.276-4.496), gastrointestinal mucositis (P<0.001, HR=10.548, 95% CI 3.245-28.576), previous exposure to broad-spectrum antibiotics within 90 days (P<0.001, HR=3.582, 95% CI 2.387-5.770) and duration of neutropenia >7 days (P<0.001,HR=4.194, 95% CI 2.572-5.618) were correlated with higher incidence of febrile during neutropenia. With the increase of the risk factors, the incidence of febrile increased gradually (35.4%, 69.2%, 86.1%, 95.6%, P<0.001). Of 784 febrile cases, 253 (32.3%) were unknown origin, 429 (54.7% )of clinical documented infections and 102(13.0%) of microbiological documented infections. The most common sites of infection were pulmonary (49.5%), upper respiratory (16.0%), crissum (9.8%), blood stream (7.7%). The most common pathogens were gram-negative bacteria (44.54%), followed by gram-positive bacteria (37.99% ) and fungi (17.47% ). There was no significant difference in mortality rates between cases with febrile and cases without febrile (9.2% vs 4.8%, P=0.099). Multivariate analysis also suggested that >40 years old (P=0.047, HR=5.000, 95% CI 0.853-28.013), hemodynamic instability (P=0.001, HR=13.185, 95% CI 2.983-54.915), prior colonization or infection by resistant pathogens (P=0.005, HR=28.734, 95% CI 2.921-313.744), blood stream infection (P=0.038, HR=9.715, 95% CI 1.110-81.969) and pulmonary

Objectives Febrile neutropenia management guidelines recommend the use of vancomycin as part of an empiric antimicrobial regimen when specific criteria are met. Often, vancomycin use among patients with febrile neutropenia is not indicated and may be over utilized for this indication. We sought to evaluate the impact of implementing a febrile neutropenia clinical pathway on empiric vancomycin use for febrile neutropenia and to identify predictors of vancomycin use when not indicated. Methods Adult febrile neutropenia patients who received initial therapy with an anti-pseudomonal beta-lactam with or without vancomycin were identified before (June 2008 to November 2010) and after (June 2012 to June 2013) pathway implementation. Patients were assessed for appropriateness of therapy based on whether the patient received vancomycin consistent with guideline recommendations. Using a comorbidity index used for risk assessment in high risk hematology/oncology patients, we evaluated whether specific comorbidities are associated with inappropriate vancomycin use in the setting of febrile neutropenia. Results A total of 206 patients were included in the pre-pathway time period with 35.9% of patients receiving vancomycin therapy that was inconsistent with the pathway. A total of 131 patients were included in the post-pathway time period with 11.4% of patients receiving vancomycin inconsistent with the pathway ( p = 0.001). None of the comorbidities assessed, nor the comorbidity index score were found to be predictors of vancomycin use inconsistent with guideline recommendations. Conclusion Our study has demonstrated that implementation of a febrile neutropenia pathway can significantly improve adherence to national guideline recommendations with respect to empiric vancomycin utilization for febrile neutropenia.

The spectrum of the clinical presentation and severity of malaria infections is broad, ranging from uncomplicated febrile illness to severe forms of disease such as cerebral malaria (CM), acute lung injury (ALI), acute respiratory distress syndrome (ARDS), pregnancy-associated malaria (PAM) or severe anemia (SA). Rodent models that mimic human CM, PAM and SA syndromes have been established. Here, we show that DBA/2 mice infected with P. berghei ANKA constitute a new model for malaria-associated ALI. Up to 60% of the mice showed dyspnea, airway obstruction and hypoxemia and died between days 7 and 12 post-infection. The most common pathological findings were pleural effusion, pulmonary hemorrhage and edema, consistent with increased lung vessel permeability, while the blood-brain barrier was intact. Malaria-associated ALI correlated with high levels of circulating VEGF, produced de novo in the spleen, and its blockage led to protection of mice from this syndrome. In addition, either splenectomization or administration of the anti-inflammatory molecule carbon monoxide led to a significant reduction in the levels of sera VEGF and to protection from ALI. The similarities between the physiopathological lesions described here and the ones occurring in humans, as well as the demonstration that VEGF is a critical host factor in the onset of malaria-associated ALI in mice, not only offers important mechanistic insights into the processes underlying the pathology related with malaria but may also pave the way for interventional studies.

This Swedish study reviewed differences in clinical presentation and laboratory findings of acute bacterial meningitis in children aged one month to 17 years in Västerbotten County, Sweden. A register-based study was performed for the period 1986 to 2013 using the Västerbotten County Council's patient registration and laboratory records at the Department of Laboratory Medicine at Umeå University Hospital. The medical records were reviewed to extract data and confirm the diagnosis. We found 103 cases of acute bacterial meningitis, and Haemophilus influenzae was the most common pathogen, causing 40.8% of all cases, followed by Streptococcus pneumoniae at 30.1% and Neisseria meningitidis at 9.7%. Significant differences in clinical presentation and laboratory findings were found. Younger children were more unwell than older ones and had more diffuse symptoms on admission. In addition, important sex-related differences were found that might explain the higher case fatality rates for boys than girls. For example, boys tended to have a higher disturbance in the blood-brain barrier, which is known to be a negative prognostic factor. This study showed that clinical presentation for acute bacterial meningitis varied with age and sex and, to a lesser extent, on the duration of the illness. ©2015 Foundation Acta Paediatrica.

We evaluated risk factors for neutropenic fever and febrile prolonged neutropenia during vincristine-including chemotherapy to treat HIV-related lymphoma to investigate whether protease inhibitor (PI) treatment is associated with infectious complications due to drug interactions with chemotherapeutic agents. We included all HIV patients who received chemotherapy including vincristine for lymphoma at a single referral center in 1999-2010. Neutropenic fever was defined as absolute neutrophil count < 500 cells/µL with body temperature over 38℃; and prolonged neutropenia was defined if it persisted over 7 days. CODOX-M/IVAC and Stanford regimens were considered high-risk regimens for prolonged neutropenia. We analyzed 48 cycles of chemotherapy in 17 HIV patients with lymphoma. There were 22 neutropenic fever and 12 febrile prolonged neutropenia events. In multivariate analysis, neutropenic fever was associated with old age and low CD4 cell count, but not with PI use or ritonavir-boosted PI use. Low CD4 cell count and high-risk regimens were associated with febrile prolonged neutropenia. Neutropenic fever and febrile prolonged neutropenia is associated with old age, low CD4 cell count, and high-risk regimens, but not PI use, in HIV patients undergoing chemotherapy including vincristine for lymphoma.

To assess the attitudes of clinicians to temperature management in haematology patients with febrile neutropenia. An online scenario-based survey was circulated to consultant members of the New Zealand branch of the Haematology Society of Australia and New Zealand, to haematology advanced trainees, and to nursing representatives at each haematology department in New Zealand. Eighty-eight responses were obtained, from 34 doctors and 54 nurses. Most respondents would advise a neutropenic patient to take paracetamol as needed for pain. Median temperature intervention threshold for an asymptomatic patient with febrile neutropenia was higher for doctors than for nurses (38.5 versus 38.0 degrees Celcius), despite considerable heterogeneity. Both groups indicated they would intervene at a median 38.0 degrees Celcius for a patient with rigors. Paracetamol was the preferred first-line cooling measure, with physical methods second-line, and pethidine third-line. All respondents favoured oral over intravenous or rectal paracetamol. Most believed a clinical trial of antipyretic treatment for febrile neutropenia was warranted, and indicated willingness to enrol their patients in such a study. This survey documents clinicians' preferred temperature intervention thresholds and methods for haematology patients with neutropenic fever, and shows considerable variation in practice. Most respondents supported a trial of antipyretic management in febrile neutropenia.

To determine the predictors and results of urine testing of young febrile infants seen in office settings. Prospective cohort study. Offices of 573 pediatric practitioners from 219 practices in the American Academy of Pediatrics Pediatric Research in Office Settings' research network. A total of 3066 infants 3 months or younger with temperatures of 38 degrees C or higher were evaluated and treated according to the judgment of their practitioners. Urine testing results, early and late urinary tract infections (UTIs), and UTIs with bacteremia. Fifty-four percent of the infants initially had urine tested, of whom 10% had a UTI. The height of the fever was associated with urine testing and a UTI among those tested (adjusted odds ratio per degree Celsius, 2.2 for both). Younger age, ill appearance, and lack of a fever source were associated with urine testing but not with a UTI, whereas lack of circumcision (adjusted odds ratio, 11.6), female sex (adjusted odds ratio, 5.4), and longer duration of fever (adjusted odds ratio, 1.8 for fever lasting > or = 24 hours) were not associated with urine testing but were associated with a UTI. Bacteremia accompanied the UTI in 10% of the patients, including 17% of those younger than 1 month. Among 807 infants not initially tested or treated with antibiotics, only 2 had a subsequent documented UTI; both did well. Practitioners order urine tests selectively, focusing on younger and more ill-appearing infants and on those without an apparent fever source. Such selective urine testing, with close follow-up, was associated with few late UTIs in this large study. Urine testing should focus particularly on uncircumcised boys, girls, the youngest and sickest infants, and those with persistent fever.

Objective Care of critically-ill children includes sedation but current therapies are suboptimal. To describe dexmedetomidine (DEX) use in children supported on mechanical ventilation for acute respiratory failure. Design Secondary analysis of data from the RESTORE clinical trial. Setting Thirty-one pediatric ICUs. Patients Data from 2449 children; 2 weeks to 17 years old. Interventions Sedation practices were unrestrained in the usual care arm. Patients were categorized as receiving dexmedetomidine as a primary sedative (DEXp), secondary sedative (DEXs), periextubation agent (DEXe), or never prescribed. DEX exposure and sedation and clinical profiles are described. Measurements and Main Results Of 1224 usual care patients, 596 (49%) received DEX. DEXp patients (N=138; 11%) were less critically ill (PRISM III-12 score median 6 [IQR 3–11]) and when compared to all other cohorts, experienced more episodic agitation. In the intervention group, time in sedation target improved from 28% to 50% within one day of initiating DEXp. DEXs usual care patients (N=280; 23%) included more children with severe PARDS or organ failure. DEXs patients experienced more inadequate pain (22% vs 11%) and sedation (31% vs 16%) events. DEXe patients (N=178; 15%) were those known to not tolerate an awake, intubated state and experienced a shorter ventilator weaning process (2.1 vs 2.3 days). Conclusions Our data support the use of dexmedetomidine as a primary agent in low criticality patients offering the benefit of rapid achievement of targeted sedation levels. Dexmedetomidine as a secondary agent does not appear to add benefit. The use of dexmedetomidine to facilitate extubation in children intolerant of an awake, intubated state may abbreviate ventilator weaning. These data support a broader armamentarium of pediatric critical care sedation. PMID:27654816

Chronic obstructive pulmonary disease (COPD) is the third leading cause of death and is a substantial source of disability in the United States. Moderate-to-severe acute exacerbations of COPD (AECOPD) can progress to respiratory failure, necessitating ventilator assistance in patients in the intensive care unit (ICU). Patients in the ICU with AECOPD requiring ventilator support have higher morbidity and mortality rates as well as costs compared with hospitalized patients not in the ICU. The mainstay of management for patients with AECOPD in the ICU includes ventilator support (noninvasive or invasive), rapid-acting inhaled bronchodilators, systemic corticosteroids, and antibiotics. However, evidence supporting these interventions for the treatment of AECOPD in critically ill patients admitted to the ICU is scant. Corticosteroids have gained widespread acceptance in the management of patients with AECOPD necessitating ventilator assistance, despite their lack of evaluation in clinical trials as well as controversies surrounding optimal dosage regimens and duration of treatment. Recent studies evaluating the safety and efficacy of corticosteroids have found that higher doses are associated with increased adverse effects, which therefore support lower dosing strategies, particularly for patients admitted to the ICU for COPD exacerbations. This review highlights recent findings from the current body of evidence on nonpharmacologic and pharmacologic treatment and prevention of AECOPD in critically ill patients. In addition, the administration of bronchodilators using novel delivery devices in the ventilated patient and the conflicting evidence surrounding antibiotic use in AECOPD in the critically ill is explored. Further clinical trials, however, are warranted to clarify the optimal pharmacotherapy management for AECOPD, particularly in critically ill patients admitted to the ICU. © 2015 Pharmacotherapy Publications, Inc.

Previous pharmacokinetic trials suggested that 40 mg subcutaneous enoxaparin once daily provided inadequate thromboprophylaxis for intensive care unit patients. Critically ill patients with acute kidney injury are at increased risk of venous thromboembolism and yet are often excluded from these trials. We hypothesized that for critically ill patients with acute kidney injury receiving continuous renal replacement therapy, a dose of 1 mg/kg enoxaparin subcutaneously once daily would improve thromboprophylaxis without increasing the risk of bleeding. In addition, we seek to utilize urine output prior to discontinuing dialysis, and low neutrophil gelatinase-associated lipocalin in dialysis-free intervals, as markers of renal recovery. In a multicenter, double-blind randomized controlled trial in progress at three intensive care units across Denmark, we randomly assign eligible critically ill adults with acute kidney injury into a treatment (1 mg/kg enoxaparin subcutaneously once daily) or control arm (40 mg enoxaparin subcutaneously once daily) upon commencement of continuous renal replacement therapy.We calculated that with 133 patients in each group, the study would have 80% power to show a 40% reduction in the relative risk of venous thromboembolism with 1 mg/kg enoxaparin, at a two-sided alpha level of 0.05. An interim analysis will be conducted after the first 67 patients have been included in each group.Enrolment began in March 2013, and will continue for two years. The primary outcome is the occurrence of venous thromboembolism. Secondary outcomes include anti-factor Xa activity, bleeding, heparin-induced thrombocytopenia, filter lifespan, length of stay, ventilator free days, and mortality. We will also monitor neutrophil gelatinase-associated lipocalin and urine volume to determine whether they can be used as prognostic factors for renal recovery. Critically ill unit patients with acute kidney injury present a particular challenge in the provision of

Rocky Mountain spotted fever (RMSF) is an emerging public health issue on some American Indian reservations in Arizona. RMSF causes an acute febrile illness that, if untreated, can cause severe illness, permanent sequelae requiring lifelong medical support, and death. We describe costs associated with medical care, loss of productivity, and death among cases of RMSF on two American Indian reservations (estimated population 20,000) between 2002 and 2011. Acute medical costs totaled more than $1.3 million. This study further estimated $181,100 in acute productivity lost due to illness, and $11.6 million in lifetime productivity lost from premature death. Aggregate costs of RMSF cases in Arizona 2002-2011 amounted to $13.2 million. We believe this to be a significant underestimate of the cost of the epidemic, but it underlines the severity of the disease and need for a more comprehensive study. © The American Society of Tropical Medicine and Hygiene.

Background: At the onset of acute hypoxic respiratory failure, critically ill patients with acute lung injury (ALI) may be difficult to distinguish from those with cardiogenic pulmonary edema (CPE). No single clinical parameter provides satisfying prediction. We hypothesized that a combination of those will facilitate early differential diagnosis. Methods: In a population-based retrospective development cohort, validated electronic surveillance identified critically ill adult patients with acute pulmonary edema. Recursive partitioning and logistic regression were used to develop a decision support tool based on routine clinical information to differentiate ALI from CPE. Performance of the score was validated in an independent cohort of referral patients. Blinded post hoc expert review served as gold standard. Results: Of 332 patients in a development cohort, expert reviewers (κ, 0.86) classified 156 as having ALI and 176 as having CPE. The validation cohort had 161 patients (ALI = 113, CPE = 48). The score was based on risk factors for ALI and CPE, age, alcohol abuse, chemotherapy, and peripheral oxygen saturation/Fio2 ratio. It demonstrated good discrimination (area under curve [AUC] = 0.81; 95% CI, 0.77-0.86) and calibration (Hosmer-Lemeshow [HL] P = .16). Similar performance was obtained in the validation cohort (AUC = 0.80; 95% CI, 0.72-0.88; HL P = .13). Conclusions: A simple decision support tool accurately classifies acute pulmonary edema, reserving advanced testing for a subset of patients in whom satisfying prediction cannot be made. This novel tool may facilitate early inclusion of patients with ALI and CPE into research studies as well as improve and rationalize clinical management and resource use. PMID:22030803

We conducted a prospective, inpatient fever study in malaria-endemic Papua, Indonesia to determine non-malaria fever etiologies. Investigations included malaria blood films, blood culture, paired serologic samples analysis for dengue, Japanese encephalitis, leptospirosis, scrub typhus, murine typhus, and spotted fever group rickettsia. During 1997–2000, 226 patients (127 males and 99 females) 1–80 years of age (median age = 25 years) were enrolled. Positive blood cultures (n = 34, 15%) were obtained for Salmonella Typhi (n = 13), Escherichia coli (n = 8), Streptococcus pneumoniae (n = 6), Staphylococcus aureus (n = 5), Streptococcus pyogenes (n = 1), and Klebsiella pneumoniae (n = 1). Twenty (8.8%) patients were positive for leptospirosis by polymerase chain reaction. Eighty (35.4%) of 226 patients had ≥ 1 positive serology, diagnostic for 15 rickettsial and 9 dengue cases. Acid-fast bacilli–positive sputum was obtained from three patients. Most common confirmed (81 of 226, 35.8%)/suspected diagnoses were typhoid fever (n = 41), pneumonia (n = 29), leptospirosis (n = 28), urinary tract infections (n = 20), rickettsioses (n = 19), dengue (n = 17), and meningitis/encephalitis (n = 15). There were 17 deaths, 7 (46.7%) were caused by meningitis/encephalitis. Multiple positive serologic results and few confirmed diagnoses indicate the need for improved diagnostics. PMID:22232450

Bacteremia is an important clinical condition in febrile neutropenia that can cause clinical failure of antimicrobial therapy. The purpose of this study was to investigate the clinical factors predictive of bacteremia in low-risk febrile neutropenia at initial patient evaluation. We performed a retrospective cohort study in a university hospital in Seoul, Korea, between May 1995 and May 2007. Patients who met the criteria of low-risk febrile neutropenia at the time of visit to emergency department after anti-cancer chemotherapy were included in the analysis. During the study period, 102 episodes of bacteremia were documented among the 993 episodes of low-risk febrile neutropenia. Single gram-negative bacteremia was most frequent. In multivariate regression analysis, initial body temperature ≥39°C, initial hypotension, presence of clinical sites of infection, presence of central venous catheter, initial absolute neutrophil count <50/mm(3), and the CRP ≥10 mg/dL were statistically significant predictors for bacteremia. A scoring system using these variables was derived and the likelihood of bacteremia was well correlated with the score points with AUC under ROC curve of 0.785. Patients with low score points had low rate of bacteremia, thus, would be candidates for outpatient-based or oral antibiotic therapy. We identified major clinical factors that can predict bacteremia in low-risk febrile neutropenia.

Many risk factors for venous thromboembolism (VTE) in hospitalized medical patients are also present in medical outpatients. VTE prevention represents an important challenge for physicians treating patients at home. The AT-HOME study was a prospective cross-sectional observational study designed to assess awareness of the risk of VTE in immobilized acutely ill medical outpatients among German physicians, many of whom were participating in a national Continuing Medical Education (CME) program designed to raise awareness of VTE. The study involved 1210 medical patients who were acutely confined to bed at home. Physicians performed a subjective assessment of VTE risk, which was rated on a 10-point scale (1 = very low risk; 10 = very high risk). The risk of VTE was also assessed retrospectively by using a scorecard developed for use in hospitalized medical patients. Of the 1210 patients, 198 (16%) had risk scores of 0-4, 319 (26%) had scores of 5 or 6, and 693 (57%) had scores > or =7. Overall, 966 patients (80%) received thromboprophylaxis. The proportion of patients receiving thromboprophylaxis was 0% to 47% in risk score groups 0-4, 76% to 85% in groups 5 and 6, and 90% to 100% in risk score groups 7-10. In the retrospective assessment of VTE risk, 74% of patients were at high risk, 15% were at intermediate risk, and 11% were at low risk. The proportions of patients receiving thromboprophylaxis in these groups were 87%, 61%, and 55%, respectively. The involvement of physicians in educational activities focusing on VTE awareness appeared to create awareness of the risks of VTE in acutely ill medical outpatients.

The Checklist for Early Recognition and Treatment of Acute Illness (CERTAIN) is an international collaborative project with the overall objective of standardizing the approach to the evaluation and treatment of critically ill patients world-wide, in accordance with best-practice principles. One of CERTAIN's key features is clinical decision support providing point-of-care information about common acute illness syndromes, procedures, and medications in an index card format. This paper describes 1) the process of developing and validating the content for point-of-care decision support, and 2) the content management system that facilitates frequent peer-review and allows rapid updates of content across different platforms (CERTAIN software, mobile apps, pdf-booklet) and different languages. Content was created based on survey results of acute care providers and validated using an open peer-review process. Over a 3 year period, CERTAIN content expanded to include 67 syndrome cards, 30 procedure cards, and 117 medication cards. 127 (59 %) cards have been peer-reviewed so far. Initially MS Word® and Dropbox® were used to create, store, and share content for peer-review. Recently Google Docs® was used to make the peer-review process more efficient. However, neither of these approaches met our security requirements nor has the capacity to instantly update the different CERTAIN platforms. Although we were able to successfully develop and validate a large inventory of clinical decision support cards in a short period of time, commercially available software solutions for content management are suboptimal. Novel custom solutions are necessary for efficient global point of care content system management.

Early diagnosis of bacteremia and sepsis in pediatric oncology patients with febrile neutropenia still remains unresolved task due to lack of sensitive and specific laboratory markers particularly at the beginning of the infectious process. The objective of our study was to assess the potentiality of interleukin-10 (IL-10) to predict or exclude bacteremia or sepsis at the beginning of febrile episode in childhood oncology patients. A total of 36 febrile neutropenic episodes in 24 children were studied. Serum samples were collected after confirmation of febrile neutropenia and analyzed using automated random access analyzer. The sensitivity of IL-10 was 73% and specificity - 92% (cut-off=18pg/ml, area under the curve - 0.87, 95% CI for sensitivity 39-94%, 95% CI for specificity 74-99%) with negative predictive value (NPV) - 83%. IL-10 evaluation might be used as an additional diagnostic tool for clinicians in excluding bacteremia or clinical sepsis in oncology patients with febrile neutropenia because of high NPV and specificity.
