The impact of eustachian tube function on intra-tympanic steroid administration.

OBJECTIVES: This study investigated the impact of eustachian tube (ET) function (ETF) on therapeutic success on candidates for intra-tympanic administration of steroids (ITAoS), due to idiopathic sudden sensorineural hearing loss (ISSNHL). METHODS: Medical chart review in two university-affiliated medical centers was performed. Included were consecutive adult patients diagnosed with unilateral ISSNHL between 2012 and 2019 who were treated with ITAoS due to incomplete or no recovery following systemic steroidal therapy. ETF was assessed by means tympanometry, before the initiation of ITAoS. The cohort was divided into an ET dysfunction group (ETD(+)) and a functioning ET group (control: ETD(-)). The audiologic response to treatment was recorded at the last follow-up. RESULTS: A total of 64 suitable patients [median (interquartile, IQR) age 49 (38-63) years] were enrolled. The ETD(+) group included 20 patients and the remaining 44 patients served as controls. Demographic and clinical parameters were not significantly different between the two groups at presentation. Hearing thresholds were improved significantly better, at frequencies 250, 500, 1, 2, 4, and 8 kHz (p = 0.001-0.040) in the ETD(+) group. CONCLUSION: ETD(+) is associated with better efficacy of ITAoS.

Prevalence of temporal bone tegmen defects among patients with Marfan syndrome.

BACKGROUND: Marfan syndrome (MFS) is a genetic disorder affecting connective tissue. The composition of the dura can change. Consequently, lumbo-sacral dural herniations and cerebrospinal fluid (CSF) leaks are encountered, however, they have yet to been described in the temporal bone. AIMS/OBJECTIVES: To define the prevalence of temporal bone meningocele or encephalocele among patients with MFS. MATERIALS AND METHODS: Reviewed medical records of all adult patients, diagnosed with MFS, who were treated between 1993 and 2018 at a single academic referral institute. Head targeted CT scans were analyzed. The presence of an anterior or lateral skull base defect was recorded. RESULTS: One-hundred and one patients diagnosed with MFS were identified. Twelve of which had suitable CT scans and were enrolled in the study. The median age of patients with defects was 65 years (range 41-71). Five of the twelve patients (41.6%) had tegmen defect. Of the seven defects found, the median size of the defects was 3 mm (range 2-5 mm). All defects were in the temporal bone, none in the anterior skull base. CONCLUSIONS AND SIGNIFICANCE: The prevalence of radiological evidence of a temporal bone defect among patients with MFS is high. This is a new, important, and potentially life-threatening association with the syndrome.

Perinatal outcome of pregnancies complicated with extreme birth weights at term.

OBJECTIVE: The objective of this study is to investigate whether an abnormal birthweight at term, either small for gestational age (SGA, < 5th centile for gestational age) or large for gestational age (LGA, > 95th centile for gestational age), is a risk factor for perinatal complications as compared with birthweight appropriate for gestational age (AGA). METHODS: A population-based retrospective cohort analysis of all singleton pregnancies delivered between 1991 and 2014 at Soroka Medical Center. Congenital malformations and multiple pregnancies were excluded. A multivariable generalized estimating equation regression model was used to control for maternal clusters and other confounders. RESULTS: During the study period, 228,242 births met the inclusion criteria, of them 91% were AGA (n = 207,652), 4.7% SGA, and 4.3% LGA. SGA significantly increased the risk for perinatal mortality (aOR 5.6, 95%CI 4.5-6.8) and low 5-min Apgar scores (aOR 2.2, 95%CI 2.0-2.4), while LGA did not. SGA and LGA were both significant risk factors for cesarean delivery. LGA was significantly associated with shoulder dystocia and post-partum hemorrhage (aOR =13.6, 95%CI 10.9-17.0, and aOR 1.7, 95%CI 1.2-2.6, respectively). CONCLUSIONS: Extreme birthweights at term are significantly associated with adverse maternal and neonatal outcomes. As opposed to SGA, LGA is not independently associated with perinatal mortality.

Epistaxis in the setting of antithrombotic therapy: A comparison between factor Xa inhibitors, warfarin, and antiplatelet agents.

OBJECTIVES/HYPOTHESIS: To describe the characteristics and severity of epistaxis in patients taking factor Xa inhibitors novel anticoagulants. STUDY DESIGN: Retrospective cohort study. METHODS: A study of adult patients hospitalized due to spontaneous epistaxis under the treatment of warfarin, rivaroxaban, or apixaban between the years 2011 and 2017 was performed. A control group of patients under antiplatelet therapy (acetylsalicylic acid, clopidogrel) was included. The mean follow-up periods in the warfarin, rivaroxaban, apixaban, and antiplatelet groups were 18, 14.5, 13.5, and 18.2 months, respectively. We compared demographics, location and severity of bleeding, treatment methods, and outcome between the groups. RESULTS: The study included 109 patients (35 under factor Xa inhibitors), the majority of whom presented with anterior epistaxis (68%). The antiplatelet group had more episodes of epistaxis prior to admission, and required endoscopic surgical control of bleeding more often, in comparison with anticoagulants (2.23 vs. 1.44, P < .05 and 23% vs. 6%, respectively, P < .05). Among anticoagulants, combined therapy (cauterization and packing) was required more frequently in the apixaban group compared to the rivaroxaban and warfarin groups (64% vs. 25% and 33%, respectively, P < .05). The rate of readmissions due to epistaxis, within 1 year of follow-up was lower in the factor Xa inhibitor groups compared with the warfarin and antiplatelet groups (16% vs. 9% and 4%, respectively, P < .05). Cessation of factor Xa inhibitor therapy was effective and uneventful with no further epistaxis events. CONCLUSIONS: Epistaxis under factor Xa inhibitors was effectively treated with no worse and perhaps even a better outcome when compared to other anticlotting medications.
