Impact of Otorrhea and Positive Cultures on Tympanoplasty Outcomes.

BACKGROUND: Chronic suppurative otitis media is a long-standing middle ear infection with a perforated tympanic membrane. Tympanoplasty is the mainstay of treatment. Most surgeons prefer to operate on dry ears; however, this may be difficult to achieve. OBJECTIVES: To investigate the effect of otorrhea and positive cultures on the outcome of tympanoplasty. METHODS: This retrospective analysis reviewed patients with chronic suppurative otitis media who underwent tympanoplasty 2008-2015. Patients were divided into three groups: active discharge and bacterial growth, active discharge without bacterial growth, and no ear discharge. Surgical outcomes were compared among the groups. RESULTS: Among 101 patients included, 43 ears (42.6%) had discharge preoperatively, 58 (57.4%) were dry. Overall closure rate was 81.2% (82/101). Preoperative active discharge closure rate was 88.3% (38/43) and without discharge 75.9% (44/58). There were 38 positive cultures preoperatively and five negative cultures. Cultures were not obtained in 58 cases. Success rates were 89.5%, 80%, and 75.9%, respectively. No significant difference was found between patients who had positive or negative cultures before the procedure (P > 0.48) or among the three groups (P = 0.25). The most common bacteria were Pseudomonas aeruginosa (n=17), followed by Staphylococcus species (n=10). None was significantly associated with operative failure (P = 0.557). The postoperative air threshold difference was not affected by culture results (P = 0.3). CONCLUSIONS: Tympanoplasty success rates and postoperative air threshold differences were not affected by the presence of preoperative otorrhea or positive ear cultures. Surgery can be performed even when the ear is not dry.

[ACUTE OTITIS MEDIA BACTERIOLOGY IN CHILDREN YOUNGER THAN THREE MONTHS IN THE LAST 16 YEARS].

BACKGROUND: Only scant information is available regarding the bacteriology of acute otitis media (AOM) in neonates. OBJECTIVES: To investigate the bacteriology of AOM post the introduction of Pneumococcal Conjugate Vaccine (PCV13) in children younger than 3 months and its relation to the mode of delivery. METHODS: Retrospective bacteriological analysis of middle ear fluids taken from children younger than 60 months suffering from AOM. The effect of PCV13 and mode of delivery, caesarian section vs vaginal delivery, on AOM bacteriology was evaluated and compared between children younger than 3 months (group 1) and children aged 3-60 months (group 2). RESULTS: The prevalence of Streptococcus pneumoniae (S.pneumoniae) and Enterobacteriaceae (E.bact) was higher in group 1 compared to group 2, 47.1% vs 35.8% and 12.3% vs 4.3%, respectively (p<0.001), while that of Haemophilus influenza (H. influenzae) and Group A streptococcus (GAS) was higher in group 2 compared to group 1, 40.3% vs 30.1% and 17.5% vs 8.3% respectively (p<0.001). The mode of delivery did not affect AOM bacteriology. The introduction of PCV13 yielded in an increase in the prevalence of GAS (7% to 15%, P<0.001) in group 1. CONCLUSIONS: S. pneumoniae and E. bact are more common AOM pathogens in neonates. Also, the prevalence of GAS was increased in this age group following the introduction of PCV13. DISCUSSION: Our results are applicable towards the formulation AOM treatment guidelines in neonates. This study contributed additional information on a topic that has not been adequately researched so far - neonatal AOM.

A Comparison of Two Widely Used Risk Stratification Systems for Thyroid Nodule Sonographic Evaluation.

BACKGROUND: The 2015 American Thyroid Association (ATA2015) and the American College of Radiology Thyroid Imaging and Reporting Data System (ACR TI-RADS) are two widely used thyroid sonographic systems. OBJECTIVES: To compare the two systems for accuracy of cancer risk prediction. METHODS: Preoperative ultrasound images from 265 patients who underwent thyroidectomy at our hospital from January 2012 to March 2019 were retrospectively categorized by the ACR TI-RADS and ATA2015 systems. Diagnostic performances were compared. RESULTS: Of 238 nodules assessed, 115 were malignant. Malignancy risks for the five ACR TI-RADS categories were 0%, 7.5%, 11.4%, 59.6%, and 90.0%. Malignancy risks for the five ATA2015 categories were 0%, 6.8%, 17.0%, 55.5%, and 92.1%. The proportion of total nodules biopsied was higher with the ATA2015 system than the ACR TI-RADS system: 88.7% vs. 66.3%. Proportions of malignant nodules and benign nodules biopsied were higher with ATA2015 than with ACR TI-RADS: 93.3% vs. 87.8% and 84.4% vs. 46.3%, respectively. Specificity and sensitivity rates were 53.6% and 84.3%, respectively, for ACR TI-RADS, and 15.5% and 93.3%, respectively, for ATA2015. The two systems showed similarly accurate diagnostic performance (AUC > 0.88). False negative rates for ACR TI-RADS and ATA2015 were 15.6% and 6.6%, respectively. Rates of missed aggressive cancer were similar for the two systems: 3.4% and 3.7%, respectively. CONCLUSIONS: ACR TI-RADS was superior to ATA2015 in specificity and avoiding unnecessary biopsies. ATA2015 yielded better sensitivity and a lower false negative rate. Identification of aggressive cancers was identical in the two systems.

Barotrauma-Induced Perilymph Fistula: Video Head Impulse Test and High-Resolution Temporal Bones Computed Tomography Role in Evaluation and FollowUp.

We report a case of a woman presenting with unilateral right profound hearing loss accompanied by vertigo secondary to barotrauma-induced perilymph fistula during recreational skydiving. Video head impulse test demonstrated a reduced gain in both the right horizontal and right anterior semicircular canals accompanied by frequently gathered overt corrective saccades. High-resolution computed tomography revealed an enlarged vestibular aqueduct on the affected side, a predisposing factor for the development of perilymph fistula. An exploratory tympanotomy was performed during which a perilymph leak was visualized at the round window niche. Temporal fascia patches enforced by absorbable gelatin sponges were applied to both round and oval windows. During post-surgery follow-up, the patient remained free of vestibular symptoms. An audiogram displayed mild improvement in the right ear speech reception threshold, although her hearing remained non-serviceable. The video head impulse test showed a favorable dynamic with a stepwise return to normal gain values in all semicircular canals and the disappearance of overt corrective saccades. This is the first case in which video head impulse test was employed as a valuable diagnostic tool for the evaluation and post-surgery follow-up of vestibular function in a barotrauma-induced perilymph fistula. The demonstration of an enlarged vestibular aqueduct on high-resolution computed tomography and the risk of perilymph fistula recurrence are discussed.

Two decades of otitis media in northern Israel: Changing trends in the offending bacteria and antibiotic susceptibility.

OBJECTIVE: Bacteriology and antibiotic resistance trends changed considerably following introduction of the pneumococcal conjugate vaccines (PCV) 7 and 13, with differences between geographic regions. The objective of this study was to evaluate changes in acute otitis media (AOM) bacteriology and antibiotic susceptibility from the pre-vaccination period (2002-2008) to after the introduction of PCV13 (2010-2019) in northern Israel. METHODS: Data were collected from 3277 middle ear fluid (MEF) cultures and 4822 common AOM-generating pathogens of children aged <5 years with otitis media, taken during 2002-2019. Age of the child, bacteriology, and antibiotic resistance were compared between 2002 and 2008, the pre-vaccination period when no vaccination was available and 2010-2019 when PCV13 was introduced. RESULTS: The mean age of the children in the pre-vaccination and the vaccination periods was 18.7 ± 13.7 and 15.7 ± 12.5 months, respectively (p < 0.001); the mean age of those with group A streptococcus (GAS) positive cultures was older, p < 0.001.The prevalence of Streptococcus pneumoniae (S. pneumoniae) decreased between those periods, from 47% to 25.8%, p < 0.001, Haemophilus influenzae (H. influenza) increased from 38.4% to 47.1%, p < 0.001, GAS increased from 12.9% to 23.8%, p < 0.001, and Moraxella catarrhalis (M. cat) increased but not statistically significant from 1.7% to 3.1%. The yearly number of positive MEF cultures decreased from 395.1 to 205.6, p < 0.001. The antibiotic sensitivity rate of almost all antibiotics increased between the two study periods. CONCLUSION: The most common MEF bacteria in northern Israel today is H. influenzae. Comparing the pre-vaccination to the vaccination period, the incidence of S. pneumonia-positive cultures decreased while GAS and H. influenza cultures increased. The age of children with positive cultures increased, and the antibiotic sensitivity rate increased.

Is Postextracapsular Tonsillectomy Bleeding More Common on the Side of the Surgeon's Nondominant Hand?

OBJECTIVES: To determine the difference in bleeding when extracapsular tonsillectomy with electrocautery is performed on the dominant and nondominant side of the surgeon's hands. STUDY DESIGN: Retrospective cohort study. SETTING: Academic university hospital. METHODS: Medical record data of patients who were admitted with posttonsillectomy bleeding from January 1, 2000, to July 31, 2017, were reviewed. Included were age, sex, surgical indication, side of posttonsillectomy bleeding, and time of bleeding. Information on the surgeon's dominant hand was also collected. All patients underwent total extracapsular resection with electrocautery. RESULTS: Of 280 patients, 186 met the inclusion criteria, 116 (62.3%) males and 70 (37.7%) females. Ages ranged from 2 to 74 years (mean ± SD, 17 ± 13 years; median, 13 years). In 136 cases (73.1%), bleeding was on the side of the surgeon's nondominant hand (P < .0001). In 50 (26.9%) cases, bleeding was on the side of the surgeon's dominant hand. The odds ratio of bleeding on the side of the surgeon's nondominant hand compared to the dominant hand was 8.99. CONCLUSION: The risk of bleeding following extracapsular tonsillectomy with electrocautery on the side of the surgeon's nondominant hand is significantly higher than on the side of the dominant hand. Thus, additional caution is required when operating on the nondominant side of the oral cavity in extracapsular tonsillectomy using electrocautery. These findings raise questions regarding dexterity as a risk factor for posttonsillectomy bleeding.

Foreign body aspiration in children: the effects of delayed diagnosis.

BACKGROUND: Foreign body aspiration is common in children, but there are no clinical clues that can determine or rule out the diagnosis before entering the operating room for bronchoscopy. The purposes of our study were to define the clinical characteristics of foreign body aspiration in the pediatric population and to evaluate the significance of delay in its diagnosis and treatment. METHODS AND RESULTS: The study used a retrospective review of 136 charts of children up to the age of 16 who underwent bronchoscopy for foreign body removal for 10 years in Ha'Emek Medical Center (Afula, Israel). An adult witness of an aspiration episode (most frequent presenting symptom), a child younger than 2 years, and an abnormal plain chest radiography were found to be significant predictors of foreign body aspiration. Estimated risk for foreign body aspiration was significantly higher in children who were younger than 2 years with an eyewitness for the aspiration episode and abnormal chest radiography (odds ratio, 5.6, with confidence interval from 2.0 to 15.6). The rate of complication was 2-fold higher in patients who arrived at the hospital 2 days or more after the aspiration compared with patients who arrived earlier. The rate of complication was 2-fold higher in patients who underwent bronchoscopy 24 hours or more after arrival at the emergency department compared with patients who underwent bronchoscopy within the first 24 hours. CONCLUSION: Delayed arrival of a child with a suspected foreign body aspiration at the hospital and delayed bronchoscopy were found to be related to a higher rate of complication.

[Foreign body aspiration in children: ten-years experience at the Ha'Emek Medical Center].

INTRODUCTION: Foreign body aspiration is common in young children. Delay in treatment may lead to complications and an emergency bronchoscopy must be performed in suspicious cases. Prevention is the most critical element needed to reduce this morbidity. PURPOSE: To examine the demographic data of children at high risk of foreign body aspiration in order to develop precautionary measures oriented to this population. METHODS: A retrospective review was prepared of all the charts of children under 16 years old who underwent bronchoscopy for suspected foreign body aspiration in Ha'Emek Medical Center during the period 1994-2004. RESULTS: The review presented a total of 136 children who had undergone bronchoscopy. Foreign bodies were found in 73% of the cases. Two thirds of the patients were male and two thirds were children less then two years old. The incidence of bronchoscopies that were positive for foreign bodies was higher in children less then two years old (82.6%) compared with older children (57.1%), p = 0.001. The incidence of Arab children was higher when compared to Jewish children and significantly higher than their percentage in the general child population (p = 0.001). The rate of bronchoscopies was 11 procedures per 100,000 children per year. In the majority of cases food was aspirated (82%) especially nuts and seeds. CONCLUSIONS: We found that children under the age of two years, male children and Arab children were at the highest risk of foreign body aspiration. Nuts and seeds are particularly dangerous and it is recommended to prevent young children from eating them. Well-defined public education programs should achieve prevention.

Comparison of safety and efficacy of foam-based versus solution-based ciprofloxacin for acute otitis externa.

OBJECTIVE: To compare and evaluate the efficacy and safety of a foam-based antibiotic formulation in the treatment of acute otitis externa (AOE) with the more conventional solution-based formulation. STUDY DESIGN: Phase 2, open-label, randomized controlled trial. SETTING: Multicenter. SUBJECTS AND METHODS: Sixty-three eligible adult patients with unilateral AOE were randomly assigned to one of two treatment groups: an experimental 0.3 percent foam-based ciprofloxacin, (FoamOtic Cipro) or 0.3 percent solution-based ciprofloxacin (Ciloxan). All patients received the same dose regime (twice daily for 7 days). The primary efficacy variable was response to therapy (cure) in the test-of-cure visit. Secondary variables included improvement of the disease symptoms otalgia, tenderness, edema, and otorrhea. RESULTS: Sixty-four patients were enrolled in the study. Seven patients were excluded from the per-protocol analysis due to major deviations from the protocol. Per-protocol analysis (n = 57) showed that cure was achieved in all the patients (P = 1.000). No significant differences were found between groups for symptomatic relief, resolution of otic discharge, or onset of pain reduction. Both treatments were found to be highly efficacious and safe, demonstrating the noninferiority of the experimental drug. CONCLUSION: Foam-based ciprofloxacin is a safe and an effective new treatment for AOE.

Peripheral facial nerve paralysis after peritonsillar infiltration of bupivacaine: a case report.

Peritonsillar infiltration of a local anesthetic solution for reduction of posttonsillectomy pain is commonly used although the benefit and complications of this technique have not yet been well established. We report a case of a 4-year-old boy who developed peripheral facial nerve paralysis after perioperative infiltration of bupivacaine and uneventful tonsillectomy. The paralysis was noticed a few minutes after extubation and resolved completely after 8 hours. We assumed this to be caused by the direct action of the local anesthetic agent on the facial nerve.
