Varicella mimicking complications of acute rhinosinusitis in an infant.

Varicella is the manifestation of primary infection with the varicella-zoster virus, mainly affecting preschool and school-aged children. The children suffer from a generalised, vesicular rash and fever. Despite the infection's typically non-threatening course, a variety of severe complications have been described.The authors present the case of a female infant suffering from varicella and developing preseptal cellulitis with a frontal abscess while being treated with intravenous antibiotics. Otorhinolaryngology consultation was sought since the clinical image was highly suggestive for sinusitis complications, namely orbital cellulitis and frontal bone osteomyelitis (Pott's puffy tumour). However, the child was below the age of frontal sinus development and there was no other apparent sign of sinonasal involvement. Ultrasonography revealed a mid-frontal collection without signs of abscess formation preseptally or postseptally, leading to the diagnosis of cutaneous superinfection of varicella lesions. The frontal abscess was drained, and the child fully recovered under antibiotic treatment.

Case Report: Petrous Apicitis and Otogenic Thrombosis of the Cavernous Sinus in a 10-Year-Old Boy.

Background: Petrous apicitis and cavernous sinus thrombosis are exceedingly rare complications of acute otitis media with only few reported cases in the post-antibiotic era. Especially in children, the appropriate management is a subject of controversy. Case Presentation: We report the case of a 10-year-old boy who presented to the emergency department with left-sided otalgia, otorrhea, and hearing loss, accompanied by somnolence and high spiking fevers. CT and MRI revealed partially obstructed mastoid air cells including a pneumatized petrous apex. Furthermore, thrombosis of the cavernous sinus and vasculitis of the internal carotid artery on the left side were present. The patient was treated with antibiotics for 6 weeks and anticoagulant therapy for 3 months. Follow-up carried out 3 months post-admission showed complete recanalization of the cavernous sinus on MRI and fatigue as the only remaining symptom. Conclusion: A complicated otitis media with petrous apicitis and cavernous sinus thrombosis in a child can in some cases be managed without a surgical intervention.

Association of epistaxis with atherosclerotic cardiovascular disease.

OBJECTIVES/HYPOTHESIS: To investigate the association between epistaxis and atherosclerotic cardiovascular disease. STUDY DESIGN: Case-control cohort study. METHODS: This study included patients from the tertiary-care ear, nose, and throat department at the University Hospital of Zurich between December 1, 2016 and June 1, 2017. We assessed the cardiovascular risk profiles in a group of 41 patients presenting with epistaxis, and a group of 41 matched controls, focusing on a surrogate parameter for atherosclerosis: the carotid intima-media thickness (CIMT). RESULTS: With a mean of 1.06 mm (standard deviation [SD] = 0.17), CIMT values were on average 26% higher in epistaxis patients than in their controls, with a mean of 0.84 mm (SD = 0.14; P < .001). Occurrence of severe epistaxis was also associated with lower ankle-brachial index values at 0.96 (SD = 0.12) versus 1.05 (SD = 0.17) (P < .001) and significantly higher QRISK2 relative risks (an algorithm for predicting cardiovascular risk) than found in the control group (1.81, SD = 0.97 vs. 1.35, SD = 0.28; P = .028). A binary logistic regression model, adjusted for possible confounders, showed an odds ratio of 2.5 for the occurrence of epistaxis per increase in CIMT of 0.1 mm in the study population (95% confidence interval: 1.56-4.11; P < .001). CONCLUSIONS: The occurrence of severe epistaxis was shown to be closely associated with the prevalence of atherosclerotic cardiovascular disease. Accordingly, patients affected by epistaxis should be regarded as at an elevated cardiovascular risk, which indicates the need for appropriate further medical assessment and preventive measures.

Factors independently associated with cardiac troponin I levels in young and healthy adults from the general population.

BACKGROUND: Determinants of cardiomyocyte injury as quantified by high-sensitivity cardiac troponin I (cTnI) in young and healthy individuals, and sex-specific 99th percentiles are largely unknown. METHODS: Our study included 2077 adults from the general population aged 25-41 years without cardiovascular disease. cTnI was measured using a high-sensitivity assay. We performed stepwise backward linear regression analyses to identify variables independently associated with hs-cTnI levels, and calculated narrow-sense heritability from 1638-genotyped participants. RESULTS: Median age was 37 years. cTnI was quantifiable in all but 11 participants (99.5 %). Median (interquartile range) cTnI was significantly higher in men than in women [0.99 (0.71; 1.65) versus 0.47 (0.33; 0.71) ng/L, p < 0.0001]. The 99th percentile of cTnI was 15.79 ng/L in men and 5.11 ng/L in women. Out of 46 variables, 22 independent determinants for cTnI were identified. The strongest associations were observed with sex, age, systolic blood pressure, heart rate, left ventricular mass, N-terminal pro B-type natriuretic peptide, and creatine kinase (all p < 0.0001). The final model explained 36 % of the overall cTnI variability. Heritability of cTnI was estimated to be 29 % (p = 0.005), but became non-significant when the residuals of the multivariable model were used for analysis (5 %, p = 0.36). CONCLUSIONS: Sex, age, and systolic blood pressure belong to the strongest determinants of hs-cTnI in healthy adults. The 99th percentile was three times higher in men compared to women. Hence, sex-specific cut-off values may be preferable when applying hs-cTnI for screening purposes. Our results may also improve the interpretation of cTn levels in daily clinical practice.
