Congenital CMV associated with diaphragm dysfunction: a rare cause of tachypnoea.

A late preterm infant with intrauterine growth restriction developed respiratory distress, tachypnoea and hypoxia after birth, requiring supplemental oxygen. Chest radiographs demonstrated persistent elevation of the right hemidiaphragm. Chest ultrasound initially demonstrated symmetrical bilateral diaphragm motion, but subsequent ultrasounds showed asymmetrical excursion with weaker movement of the right hemidiaphragm. Placental pathology demonstrated chronic infectious villitis secondary to cytomegalovirus (CMV), and subsequent CMV testing on the infant was positive. The infant was microcephalic and head imaging revealed intracranial calcifications, consistent with congenital CMV infection.CMV is the most common congenital infection and has a wide array of clinical manifestations. This report highlights the rarely described association between congenital CMV infection and respiratory distress due to underlying diaphragm dysfunction. In neonates with respiratory distress and features of congenital CMV infection, clinicians should have a high index of suspicion for diaphragm dysfunction.

Heart rate and respiratory rate in predicting risk of serious bacterial infection in febrile children given antipyretics: prospective observational study.

Clinical algorithms used in the assessment of febrile children in the Paediatric Emergency Departments are commonly based on threshold values for vital signs, which in children with fever are often outside the normal range. Our aim was to assess the diagnostic value of heart and respiratory rate for serious bacterial infection (SBI) in children after temperature lowering following administration of antipyretics. A prospective cohort of children presenting with fever between June 2014 and March 2015 at the Paediatric Emergency Department of a large teaching hospital in London, UK, was performed. Seven hundred forty children aged 1 month-16 years presenting with a fever and ≥ 1 warning signs of SBI given antipyretics were included. Tachycardia or tachypnoea were defined by different threshold values: (a) APLS threshold values, (b) age-specific and temperature-adjusted centiles charts and (c) relative difference in z-score. SBI was defined by a composite reference standard (cultures from a sterile site, microbiology and virology results, radiological abnormalities, expert panel). Persistent tachypnoea after body temperature lowering was an important predictor of SBI (OR 1.92, 95% CI 1.15, 3.30). This effect was only observed for pneumonia but not other SBIs. Threshold values for tachypnoea > 97th centile at repeat measurement achieved high specificity (0.95 (0.93, 0.96)) and positive likelihood ratios (LR + 3.25 (1.73, 6.11)) and may be useful for ruling in SBI, specifically pneumonia. Persistent tachycardia was not an independent predictor of SBI and had limited value as a diagnostic test.  Conclusion: Among children given antipyretics, tachypnoea at repeat measurement had some value in predicting SBI and was useful to rule in pneumonia. The diagnostic value of tachycardia was poor. Overreliance on heart rate as a diagnostic feature following body temperature lowering may not be justified to facilitate safe discharge. What is Known: • Abnormal vital signs at triage have limited value as a diagnostic test to identify children with SBI, and fever alters the specificity of commonly used threshold values for vital signs. • The observed temperature response after antipyretics is not a clinically useful indicator to differentiate the cause of febrile illness. What is New: • Persistent tachycardia following reduction in body temperature was not associated with an increased risk of SBI and of poor value as a diagnostic test, whilst persistent tachypnoea may indicate the presence of pneumonia.

Impact of precipitous labor on the onset of transient tachypnea in vaginal deliveries at term.

OBJECTIVE: The objective of the present research was to study the association between precipitous labor (less than 3 h) and the onset of transient tachypnea in singleton fetuses in cephalic presentation with term vaginal deliveries. METHODS: This cohort study included women delivered from 2013 through 2017 in our French tertiary university hospital maternity unit. Inclusion criteria were vaginal delivery of liveborn singleton fetus in cephalic presentation and at term. We compared women with precipitous labor and those with longer labor. The principal endpoint was the rate of transient tachypnea of the newborn (TTN). We investigated risk factors for TTN besides duration of labor. RESULTS: Comparison of 2644 women with precipitous labor and 7571 with longer labor showed a lower TTN rate in the precipitous labor group (1.6 vs 2.7%; P = 0.003). The association was no longer significant after adjustment for the risk factors identified in the univariate analysis (adjusted OR 0.99, 95% CI 0.64-1.54). Risk factors identified for TTN were non-clear amniotic fluid, shoulder dystocia, umbilical cord encirclement, birth weight less than 2500 g, use of cervical ripening and operative vaginal delivery. CONCLUSION: Precipitous labor, lasting less than 3 h, is not associated with a higher risk of transient tachypnea in term newborns after vaginal delivery.

The role of body temperature on respiratory rate in children with acute respiratory infections.

BACKGROUND: The World Health Organization (WHO) recommends the use of tachypnea as a proxy to the diagnosis of pneumonia. OBJECTIVE: The purpose of this study was to examine the relationship between body temperature alterations and respiratory rate (RR) difference (RRD) in children with acute respiratory infections(ARI). METHODS: This cross-sectional study included 297 children with age 2-60 months who presented with cough and fever at the pediatric emergency and outpatient clinics in the Department of Pediatrics, Baskent University Hospital, from January 2016 through June 2018. Each parent completed a structured questionnaire to collect background data. Weight and height were taken. Body temperature, respiratory rate, presence of the chest indrawing, rales, wheezing and laryngeal stridor were also recorded. RRD was defined as the differences in RR at admission and after 3 days of treatment. RESULTS: Both respiratory rate and RRD were moderately correlated with body temperature (r=0.71, p<0.001 and r=0.65, p<0.001; respectively). For every 1°C increase in temperature, RRD increased by 5.7/minutes in overall, 7.2/minute in the patients under 12 months of age, 6.4/minute in the female. The relationship between body temperature and RRD wasn't statistically significant in patients with rhonchi, chest indrawing, and low oxygen saturation. CONCLUSION: Respiratory rate should be evaluated according to the degree of body temperature in children with ARI. However, the interaction between body temperature and respiratory rate could not be observed in cases with rhonchi and severe pneumonia.

Hipertensión arterial por hiperactividad simpática tras traumatismo craneoencefálico grave / Hypertension due to sympathetic hyperactivity after severe head injury

Presentamos el caso de un paciente de 34 años que sufre un traumatismo craneoencefálico grave con afectación cerebral severa. Evoluciona de manera tórpida precisando varias reintervenciones por sangrado y herniación de masa encefálica. Nos interconsultan desde Neurocirugía por irregular control de cifras de presión arterial a pesar de tratamiento con calcioantagonistas. El paciente asocia diaforesis, taquipnea y taquicardia, junto a fiebre de alto grado de forma persistente sin evidencia microbiológica. Analítica con función renal normal, sin proteinuria y sin datos de hipertrofia de ventrículo izquierdo que sugieran hipertensión arterial previa. Esto nos hace plantearnos como primera posibilidad diagnóstica un síndrome de hiperactividad simpática debido al daño neurológico severo. Se inicia terapia antihipertensiva orientada a esta sospecha, entre los que se incluyen betabloqueantes no cardioselectivos, alfa-2-agonistas, benzodiacepinas y agonistas de los receptores GABA. Así se consigue mejorar la labilidad de las cifras de presión arterial, lo que apoya el diagnóstico

We present the case of a 34-year-old patient with severe head trauma and severe brain involvement. The patient deteriorated progressively and required several reinterventions for bleeding and brain herniation. We were consulted by neurosurgery due to irregular blood pressure control despite treatment with calcium antagonists. The patient had associated diaphoresis, tachypnoea and tachycardia, together with persistent high-grade fever with no microbiological evidence. Laboratory tests showed normal kidney function, with no proteinuria and no signs of left ventricular hypertrophy to suggest previous arterial hypertension. This led us to consider sympathetic hyperactivity syndrome as a first possible diagnosis due to severe neurological damage. In line with this suspicion, antihypertensive therapy was initiated which included non-cardioselective beta-blockers, alpha-2 agonists, benzodiazepines and GABA receptor agonists. Thus, we were able to improve the labile blood pressure levels, which supports the diagnosis

Risk factors for early mortality in patients with pulmonary tuberculosis admitted to the emergency room.

BACKGROUND AND OBJECTIVES: Mortality of patients with pulmonary tuberculosis (TB) admitted to emergency departments is high. This study was aimed at analysing the risk factors associated with early mortality and designing a risk score based on simple parameters. METHODS: This prospective case-control study enrolled patients admitted to the emergency department of a referral TB hospital. Clinical, radiological, biochemical and microbiological risk factors associated with death were compared among patients dying within one week from admission (cases) and those surviving (controls). RESULTS: Forty-nine of 250 patients (19.6%) experienced early mortality. Multiple logistic regression analysis showed that oxygen saturation (SaO2) ≤90%, severe malnutrition, tachypnoea, tachycardia, hypotension, advanced disease at chest radiography, severe anaemia, hyponatremia, hypoproteinemia and hypercapnia were independently and significantly associated with early mortality. A clinical scoring system was further designed to stratify the risk of death by selecting five simple parameters (SpO2 ≤ 90%, tachypnoea, hypotension, advanced disease at chest radiography and tachycardia). This model predicted early mortality with a positive predictive value of 94.88% and a negative predictive value of 19.90%. CONCLUSIONS: The scoring system based on simple parameters may help to refer severely ill patients early to a higher level to reduce mortality, improve success rates, minimise the need for pulmonary rehabilitation and prevent post-treatment sequelae.

Clinical Predictors Influencing the Length of Stay in Emergency Department Patients Presenting with Acute Heart Failure.

Background and objectives: Acute heart failure is a common problem encountered in the emergency department (ED). More than 80% of the patients with the condition subsequently require lengthy and repeated hospitalization. In a setting with limited in-patient capacity, the patient flow is often obstructed. Appropriate disposition decisions must be made by emergency physicians to deliver effective care and alleviate ED overcrowding. This study aimed to explore clinical predictors influencing the length of stay (LOS) in patients with acute heart failure who present to the ED. Materials and Methods: We conducted prognostic factor research with a retrospective cohort design. Medical records of patients with acute heart failure who presented to the ED of Ramathibodi Hospital from January to December 2015 were assessed for eligibility. Thirteen potential clinical predictors were selected as candidates for statistical modeling based on previous reports. Multivariable Poisson regression was used to estimate the difference in LOS between patients with and without potential predictors. Results: A total of 207 patients were included in the analysis. Most patients were male with a mean age of 74.2 ± 12.5 years. The median LOS was 54.6 h (Interquartile range 17.5, 149.3 h). From the multivariable analysis, four clinical characteristics were identified as independent predictors with an increase in LOS. These were patients with New York Heart Association (NYHA) functional class III/IV (+72.9 h, 95%Confidence interval (CI) 23.9, 121.8, p = 0.004), respiratory rate >24 per minute (+80.7 h, 95%CI 28.0, 133.3, p = 0.003), hemoglobin level <10 mg/dL (+60.4 h, 95%CI 8.6, 112.3, p = 0.022), and serum albumin <3.5 g/dL (+52.8 h, 95%CI 3.6, 102.0, p = 0.035). Conclusions: Poor NYHA functional class, tachypnea, anemia, and hypoalbuminemia are significant clinical predictors of patients with acute heart failure who required longer LOS.

Does recombinant human erythropoietin administration in critically ill COVID-19 patients have miraculous therapeutic effects?

An 80-year-old man with multiple comorbidities presented to the emergency department with tachypnea, tachycardia, fever, and critically low O2 saturation and definitive chest computerized tomography scan findings in favor of COVID-19 and positive PCR results in 48 hours. He received antiviral treatment plus recombinant human erythropoietin (rhEPO) due to his severe anemia. After 7 days of treatment, he was discharged with miraculous improvement in his symptoms and hemoglobin level. We concluded that rhEPO could attenuate respiratory distress syndrome and confront the severe acute respiratory syndrome coronavirus 2 virus through multiple mechanisms including cytokine modulation, antiapoptotic effects, leukocyte release from bone marrow, and iron redistribution away from the intracellular virus.

Inflammatory signs and epileptic crisis in patients admitted in an emergency unit.

OBJECTIVE: To evaluate inflammatory signs presented in medical records of patients with a main diagnosis of epileptic seizures, admitted in an emergency unit. METHOD: Cross-sectional and retrospective study. The sample was composed of 191 medical records, from children, adolescents, adults, and elders, with a clinical diagnosis of epileptic seizures, admitted between June 2016 and June 2017 at the emergency unit of a hospital in Porto Alegre/RS. RESULTS: The prevalent inflammatory signs were tachypnea (33.5%) and/or fever (27.2%) associated with leukocytosis (P=0.030). Children/adolescents had seizures less frequently (P=0.010) and these were due to fever (P=0.000). Adults presented seizures more frequently (P=0.006), which were related to medication/intoxication (P=0.000). In elders, seizures occurred due to metabolic or circulatory abnormalities (P=0.000), less often due to fever (P=0.005). CONCLUSION: Seizures are related to fever and tachypnea, being caused by different etiologies according to age, being more frequent in adults. Fever is related to leukocytosis, regardless of age.
