RESUMO

Aim: Preventing unnecessarily long durations of antibiotic therapy is a key opportunity to reduce antibiotic overuse in children 2 years of age and older with acute otitis media (AOM). Pragmatic interventions to reduce durations of therapy that can be effectively scaled and sustained are urgently needed. This study aims to fill this gap by evaluating the effectiveness and implementation outcomes of two low-cost interventions of differing intensities to increase guideline-concordant antibiotic durations in children with AOM. Methods: The higher intensity intervention will consist of clinician education regarding guideline-recommended short durations of antibiotic therapy; electronic health record (EHR) prescription field changes to promote prescribing of recommended short durations; and individualized clinician audit and feedback on adherence to recommended short durations of therapy in comparison to peers, while the lower intensity intervention will consist only of clinician education and EHR changes. We will explore the differences in implementation effectiveness by patient population served, clinician type, clinical setting and organization as well as intervention type. The fidelity, feasibility, acceptability and perceived appropriateness of the interventions among different clinician types, patient populations, clinical settings and intervention type will be compared. We will also conduct formative qualitative interviews with clinicians and administrators and focus groups with parents of patients to further inform the interventions and study. The formative evaluation will take place over 1.5 years, the interventions will be implemented over 2 years and evaluation of the interventions will take place over 1.5 years. Discussion: The results of this study will provide a framework for other healthcare systems to address the widespread problem of excessive durations of therapy for AOM and inform national antibiotic stewardship policy development. Clinical Trial Registration: NCT05608993 (ClinicalTrials.gov).

RESUMO

OBJECTIVES: To determine the aetiological pathogens causing ear infections and their antimicrobial susceptibility patterns among patients with ear complaints at a tertiary hospital in Dar es Salaam. DESIGN: Hospital-based cross-sectional study. SETTINGS: Otorhinolaryngology clinic at Muhimbili National Hospital, Dar es Salaam, Tanzania. PARTICIPANTS: Patients presenting with signs and symptoms of ear infection. MAIN OUTCOME MEASURE: Bacteria and fungi isolated from ear swab specimens of patients presenting with signs and symptoms of ear infection; and antimicrobial susceptibility patterns of isolated bacteria. RESULTS: Two hundred and fifty-five participants were enrolled, with a median age of 31 years and an IQR of 15-49. Otitis externa was the predominant type of ear infection, accounting for 45.1%. We observed positive bacteria culture in 53.3% of study participants, in which 41% of isolates were obtained from patients with chronic suppurative otitis media. Moreover, Staphylococcus aureus (27.3%) and Pseudomonas aeruginosa (24.2%) were the most frequently isolated bacteria, while Candida spp, 12 (63.8%) and Aspergillus spp, 9 (36.2%) were the only isolated fungi. Furthermore, we report that 93% of isolated Enterobacterales were resistant to amoxicillin/clavulanic acid, and 73% were resistant to ceftazidime. In addition, we detected 34.4% extended-spectrum beta-lactamase-producing Enterobacterales (ESBL-PE) and 44.4% methicillin-resistance S. aureus (MRSA). We also found that 22% of the bacteria isolates were resistant to ciprofloxacin, a primary topical antibiotic used in managing ear infections. CONCLUSIONS: The findings from this study reveal that the leading aetiological agent of ear infection is bacteria. Furthermore, our findings show a significant proportion of ESBL-PE and MRSA-causing ear infections. Hence, detecting multidrug-resistant bacteria is crucial to improving ear infection management.

RESUMO

Introduction/Rationale: Tuberculosis remains a major public health issue. It is an opportunistic pathology, very common in HIV-immunocompromised persons, classifying it at the WHO stage 4. Ear tuberculosis remains a rare and under-diagnosed clinical form. We report here a case of ear tuberculosis concomitant with pulmonary localization in an HIV-immunosuppressed person on triple antiretroviral therapy aged 32 years hospitalized in Bamako (Mali) to discuss the diagnostic and therapeutic difficulties posed by this rare localization. Description of the case: The patient had a chronic productive cough, otalgia and right chronic purulent otorrhea. The search for acid-resistant bacilli was positive for direct examination in gastric casing fluid and swabbing of the ear pus, confirming the diagnosis of tuberculosis. Anti-tuberculosis treatment instituted for 6 months associated with adjuvants resulted in complete healing of the patient. Discussion/conclusion: Although rare, ear localization must be actively sought. Etiological treatment must be instituted upon confirmation of the diagnosis to avoid complications and sequelae.

RESUMO

OBJECTIVE: Hearing loss occurring in temporal association with the topical application of otic medications is regularly reported to the Federal Office of Consumer Protection and Food Safety (Bundesamt für Verbraucherschutz und Lebensmittelsicherheit - BVL) in the form of adverse event (AE) reports. Although deafness or impaired hearing are listed as possible adverse reactions in the Summary of Product Characteristics of the otic medications approved in Germany little information about the underlying causes is available to date. MATERIAL AND METHODS: A search for cases reporting impaired hearing following the use of otic medication was conducted in the national AE database. Subsequently, descriptive analysis was performed. Due to their small number, cases involving cats were excluded. Possible risk factors and causes of hearing loss were considered against the background of current literature. RESULTS: While dogs of all age groups were affected, the majority of reports referred to dogs older than 10 years of age. Besides crossbreds, dogs of the breeds West Highland White Terrier, Dalmatian, Miniature Poodle and French Bulldog were most frequently involved. The analysis of the available data does not point to specific products or active substances that could be associated with a more frequent occurrence of hearing loss. CONCLUSION AND CLINICAL RELEVANCE: In addition to possible ototoxicity of a product, other causes of hearing loss should be considered. These include the underlying otitis itself, age-related hearing loss, previously undetected unilateral congenital deafness, or conductive deafness due to obstruction of the ear canal. Treatment options include discontinuation of potentially ototoxic substances or treatment of conductive deafness, e. g. by removal of drug residues and exudate or treatment of otitis media. In the case of hearing loss subsequent to the use of otic medication, the BVL should be notified of this event in as much detail as possible in order to further improve the data situation concerning this topic.

RESUMO

Pseudomonas aeruginosa (P. aeruginosa) can cause otitis in dogs that is nonresponsive to empirical therapy. This study evaluated P. aeruginosa isolates (N = 216) from canine ear swabs submitted to the Kansas State Veterinary Diagnostic Laboratory from 2018-2020 to create an antibiogram and minimum inhibitory concentration distributions using Clinical Laboratory Standards Institutes breakpoints. Multidrug resistance was defined as non-susceptibility to ≥1 drug from ≥3 antimicrobial classes. Submitting veterinarians (N = 83) were invited to complete a survey about antimicrobial use and otitis management. Susceptibility was higher for aminoglycosides [gentamicin (82%, 177/216) and amikacin (81%, 175/216)] than fluoroquinolones [marbofloxacin (67%, 145/216), enrofloxacin (32%, 70/216), and orbifloxacin (18%, 39/216)]. Most responding veterinarians (54%, 15/28) prescribe topical aminoglycosides as first-line therapy for canine otitis, but 71% (15/21) prescribe fluoroquinolones if rods are seen cytologically. Ceftazidime, imipenem, and piperacillin-tazobactam showed high susceptibility and are used rarely. Multidrug resistance was present in 13% (28/216) of isolates. Based on in vitro susceptibility, topical aminoglycosides might be more effective than fluoroquinolones for P. aeruginosa otitis, but efficacy studies are required. Susceptibility testing is encouraged for cases not responding to empirical therapy but has limitations because topical preparations have high concentrations and otic breakpoints are not available.

RESUMO

Within this study, new materials were synthesized and characterized based on polysiloxane modified with different ratios of N-acetyl-l-cysteine (NAC) and crosslinked via UV-assisted thiol-ene addition, in order to obtain efficient membranes able to resist bacterial adherence and biofilm formation. These membranes were subjected to in vitro testing for microbial adherence against S. pneumoniae using standardized tests. WISTAR rats were implanted for 4 weeks with crosslinked siloxane samples without and with NAC. A set of physical characterization methods was employed to assess the chemical structure and morphological aspects of the new synthetized materials before and after contact with the microbiological medium.

RESUMO

BACKGROUND: The chemical composition and biological activity of Eucalyptus essential oils have been studied extensively (EOs). A few of them were tested for antibacterial effectiveness against otitis strains. The chemical composition and antibacterial activity of the EOs of eight Tunisian Eucalyptus species were assessed in the present study. METHODS: Hydrodistillation was used to extract EOs from the dried leaves of eight Eucalyptus species: Eucalyptus accedens, Eucalyptus punctata, Eucalyptus robusta, Eucalyptus bosistoana, Eucalyptus cladocalyx, Eucalyptus lesouefii, Eucalyptus melliodora and Eucalyptus wandoo. They are assessed by GC/MS and GC/FID and evaluated for antibacterial activity using agar diffusion and broth microdilution techniques against three bacterial isolates (Haemophilus influenzae, Haemophilus parainfluenzae, Klebsiella pneumoniae) and three reference bacteria strains (Pseudomonas aeruginosa, ATTC 9027; Staphylococcus aureus, ATCC 6538; and Escherichia coli, ATCC 8739). Furthermore, the selected twenty-one major compounds and all values of the inhibition zone diameters were subjected to further statistical analysis using PCA and HCA. RESULTS: The EO yields of the studied Eucalyptus species range from 1.4 ± 0.4% to 5.2 ± 0.3%. Among all the species studied, E. lesouefii had the greatest mean percentage of EOs. The identification of 128 components by GC (RI) and GC/MS allowed for 93.6% - 97.7% of the total oil to be identified. 1,8-cineole was the most abundant component found, followed by α-pinene, p-cymene, and globulol. The chemical components of the eight EOs, extracted from the leaves of Eucalyptus species, were clustered into seven groups using PCA and HCA analyses, with each group forming a chemotype. The PCA and HCA analyses of antibacterial activity, on the other hand, identified five groups. CONCLUSION: The oils of E. melliodora, E. bosistoana, and E. robusta show promise as antibiotic alternatives in the treatment of otitis media.

RESUMO

A 10-year-old canine with chronic unilateral otitis and a history of unsuccessful systemic and topical antibiotic treatments was referred. A computer tomography scan (CT scan) revealed unilateral chronic otitis with calcification of the ear canal, abscessation and fistula. On bacterial culture a Staphylococcus pseudintermedius sensitive to pradofloxacin was isolated. Systemic treatment with pradofloxacin, 3 mg/kg per os once daily, improved the infection and the dog had total ear canal ablation and bulla osteotomy performed. After one month, despite antibiotic treatment new fistulas developed in the same area. Bacterial culture revealed an drug-resistant S. pseudintermedius sensitive only to rifampicin. Under general anesthesia, the area was cleaned with 0.5% saline solution and 1 mL of indocyanine green (Emundo®, A.R.C.) was injected into the fistulas. A treatment with diode laser (A.R.C. Laser 810 nm, GmbH, Nurnberg, Germany) of four cycles 500 mw for 30 s, with a dosage of 50 J/cm2 in the effected area was performed. No antibiotic was administered and one week later, 50% of the fistulas were closed with a significant improvement of the patient's clinical condition. Cytology and bacterial culture were negative 72 h after the treatment. Total recovery occurred after two weeks. Photodynamic Therapy(PDT) is a promising antibacterial technique in case of localized refractory bacterial infections.

RESUMO

BACKGROUND: The increasing threat of bacterial resistance promotes the need for antibiotic stewardship programs to foster responsible antimicrobial use. Therefore, guidelines for prudent use supported by an online stewardship tool (AntibioticScout.ch) were introduced in Switzerland in December 2016. They recommend (with decreasing preference) a first, second or third line antimicrobial for treatment. The objective of this study was to evaluate antimicrobial prescriptions for Swiss calves before (2016) and after (2018) the launch of these guidelines. Cases of calves with pneumonia, diarrhea and otitis from a university hospital and eight private practices in Switzerland were included. Data on anamnesis, clinical findings, diagnostic work-up and treatment were collected. Type and percentages [95% confidence interval] of antimicrobial prescriptions were compared between 2016 and 2018. RESULTS: Of the total number of calves, 88.2% [85.4-90.6] in 2016 (n = 625) and 88.4% [85.7-90.7] in 2018 (n = 655) were treated with antibiotics. The use of highest priority critically important antimicrobials (HPCIAs) decreased from 52.7% [48.6-56.9] in 2016 to 38.0% [34.2-41.9] in 2018; this decrease was found at the university hospital and in private practice and in cases with pneumonia and diarrhea. Particularly the use of fluoroquinolones decreased (2016: 43.1% [39.2-47.2]; 2018: 31.1% [27.6-34.8]). Overall, the number of first line treatments increased from 12.8% [10.4-15.6] in 2016 to 20.2% [17.3-23.4] in 2018. In cases of pneumonia, first line treatments increased (2016: 15.3% [11.6-19.9]; 2018: 26.5% [21.8-31.9]) and third line treatments decreased (2016: 43.5% [38.0-49.3]; 2018: 27.9% [23.1-33.3]); this was seen at the university hospital, whereas in private practice only a decrease of third line treatments was observed. In cases of diarrhea, more second line at the expense of unlisted antimicrobials were prescribed at the university hospital in 2018. Antimicrobial treatment of calves with otitis did not change from 2016 to 2018. CONCLUSIONS: After the introduction of AntibioticScout.ch, more prudent use was observed in the treatment of calves with pneumonia and diarrhea as less HPCIAs, particularly fluoroquinolones, and more first line antimicrobials were prescribed. However, the overall frequency of antimicrobial treatment did not change and the use of HPCIAs was still common in 2018, especially in private practices. Therefore, further antimicrobial stewardship activities are necessary.

RESUMO

ETHNOPHARMACOLOGICAL RELEVANCE: Nymphaea hybrida Peck is used as a traditional medicinal herb for treating pain and inflammatory diseases, and known for its ornamental value and as a hot drink. However, the effects of N. hybrida polar fractions on lipopolysaccharide (LPS)-induced in vitro inflammation model and acute inflammation murine models have yet to be evaluated. AIM OF THE STUDY: The aim of this study was to elucidate the anti-inflammatory effects of N. hybrida ethanol extract (NHE) and its polar fractions: petroleum ether (PE), methylene chloride (MC), ethyl acetate (EA), methanol (ME), and water (WA). The underlying molecular mechanisms of active fraction in LPS-stimulated RAW 264.7 murine macrophages were further investigated. MATERIAL AND METHODS: Fractions with potential anti-inflammatory effects were screened using direct nitric oxide (NO) radical scavenging and cyclooxygenase (COX)-2 inhibition assays in vitro. The anti-inflammatory properties of potential fraction were evaluated in LPS-stimulated RAW264.7 cells, xylene-induced ear edema, carrageenan-induced paw edema and xylene-induced Evans blue exudation of acute inflammation murine models. The regulation of nuclear factor-κB (NF-κB) and mitogen-activated protein kinase (MAPK) signaling pathways were investigated using western blotting and immunofluorescence. RESULTS: Compared to other polar fractions, NHE-EA displayed higher phenol and flavonoid content, and exerted greater activity in direct NO radical scavenging and COX-2 inhibition assay in vitro. NHE-EA markedly decreased the levels of inflammatory mediators, NO and prostaglandin E2 (PGE2), by suppressing the over-expression of inducible nitric oxide synthase (iNOS) and COX-2 in LPS-stimulated RAW264.7 cells. The NHE-EA fraction dose-dependently alleviated over-elevation of LPS-associated intracellular calcium and decreased the abnormal secretion of pro-inflammatory cytokines, tumor necrosis factor-α (TNF-α), interleukin-1ß (IL-1ß), IL-6, and interferon-γ (IFN-γ). The combination with NHE-EA effectively attenuated the activation and nuclear translocation of NF-κB p65, and the phosphorylation of extracellular signal-regulated kinases (ERK), c-Jun N-terminal kinases (JNK), and p38 kinases of MAPK pathways. NHE-EA could significantly ameliorate the degree of swelling of the mice ear and paw, the skin exudation of Evans blue and the excessive secretion of inflammatory cytokines. CONCLUSION: Our results demonstrated that NHE-EA was the most active polar fraction of N. hybrida extracts. It inhibited the LPS-associated inflammatory response by blocking the activation of NF-κB and MAPKs pathways in RAW264.7 cells. It also effectively alleviated the inflammatory response of acute inflammation. These results indicated the role of NHE-EA as adjuvants and their potential role in alternative strategy for the treatment of inflammatory diseases.

RESUMO

BACKGROUND: Antibiotic resistant bacteria particularly extended-spectrum beta lactamase (ESBL) producing are of major concern for management of outpatients. They can spread rapidly and are associated with poor patient outcome. However, there is scarcity of information on ear infection with ESBL producing bacteria in Ethiopia. Therefore, this study investigates the prevalence of ear infection with ESBL producing bacteria among outpatients attending Felegehiwot Referral Hospital, Northwest Ethiopia. METHODS: A hospital based cross-sectional study was conducted from May, 2018 to January, 2019. Demographic and clinical data were collected with face to face interview and were complemented with patient card review. Ear discharge specimens were collected from study participants using swab technique. All ear swab specimens were cultured using standard microbiological techniques. The ESBL producing bacteria were detected by double disc synergy test and interpreted based on Clinical and laboratory Standards Institute Guidelines. Chi-square and fisher's exact tests were calculated to check association between variables. RESULTS: A total of 236 patients (male = 138 and female = 98) with ear infection took part in the study. The median age of the participants was 20years. Overall, 10 (4.23%, 95%CI; 2.3-7.6%) of patients had ear infection with ESBL producing bacteria. Other chronic illnesses (p = 0.003), history of hospital visit and treatment (p = 0.006) and history of antibiotic use without physician's prescription (p<0.001) had significant association with prevalence of ESBL producing bacteria in ear infection. The proportion of ear infection with ESBL producing P.mirabilis, P.aeruginosa and K.pneumoniae were 4 (1.7%), 3 (1.3%) and 2 (0.8%), respectively. All ESBL producing isolates were MDR (100%). Overall, 58 (43%) species were MDR. P.aeruginosa was the leading MDR isolate 29 (53.7%).For all bacterial isolates of ear infection, ampicillin(93.3%) and amoxicillin-clavulanic acid (58.5%) revealed high level of resistance whereas low resistance rates were observed for ciprofloxacin (5.2%), third generation cephalosporin (11.9-20%) and aztreonam (16.3%). CONCLUSIONS: Ear infection due to ESBL producing bacteria coupled with high levels of MDR is becoming a growing concern for outpatients in the study area. Regular detection of these bacteria and wise use of antibiotics are needed to stop the spread of this form of resistance.

RESUMO

Sea cucumber body wall contains several naturally occurring bioactive components that possess health-promoting properties. Isostichopus badionotus from Yucatan, Mexico is heavily fished, but little is known about its bioactive constituents. We previously established that I. badionotus meal had potent anti-inflammatory properties in vivo. We have now screened some of its constituents for anti-inflammatory activity in vitro. Glycosaminoglycan and soluble protein preparations reduced 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced inflammatory responses in HaCaT cells while an ethanol extract had a limited effect. The primary glycosaminoglycan (fucosylated chondroitin sulfate; FCS) was purified and tested for anti-inflammatory activity in vivo. FCS modulated the expression of critical genes, including NF-ĸB, TNFα, iNOS, and COX-2, and attenuated inflammation and tissue damage caused by TPA in a mouse ear inflammation model. It also mitigated colonic colitis caused in mice by dextran sodium sulfate. FCS from I. badionotus of the Yucatan Peninsula thus had strong anti-inflammatory properties in vivo.

RESUMO

OBJECTIVES: Staphylococcus epidermidis is the most common coagulase-negative Staphylococcus colonising the human skin and mucous membranes and is a major cause of nosocomial infections. Antimicrobial resistance (AMR) in S. epidermidis has increased significantly in the last few decades, threatening human health globally. METHODS: This study explored the AMR status in an S. epidermidis isolate (AK-612) from an ear infection of an Iraqi student who had undergone treatment for the same. Whole-genome sequence analysis was also performed. RESULTS: Strain AK-612 is a methicillin-resistant S. epidermidis (MRSE) isolate possessing an SCCmec type V element. Strain AK-612 belongs to sequence type 35 (ST35), clonal complex 2 (CC2), which to the best of our knowledge has not been reported previously in Iraq, having been previously reported only in Portugal and Germany. In Portugal, S. epidermidis ST35 was reported to colonise the nasal area of a bird of prey (Buteo buteo) that undergoes a migratory period extending its range from Europe to Asia. The plasmid of S. epidermidis AK-612 showed greatest identity with plasmid 1 of S. epidermidis strain PM221, which was isolated in Finland from an intramammary bovine infection. This ST35 strain may have crossed continental boundaries and expanded its occurrence in animals and humans. CONCLUSION: This is a matter of serious concern as the dissemination of multidrug-resistant S. epidermidis in human infections is a major hindrance for the treatment of these infections. Transmission of this isolate across continental boundaries will make infection control a difficult task.

RESUMO

In recent years, new progress has been made regarding the diagnosis, treatment and prevention of acute otitis media (AOM). The Italian Pediatric Society therefore decided to issue an update to the previous guidelines published in 2010. Literature searches were conducted on MEDLINE by Pubmed, including studies in children, in English or Italian, published between January 1, 2010, and December 31, 2018. The quality of the included studies was assessed using the grading of recommendations, assessment, development and evaluations (GRADE) methodology. In particular, the quality of the systematic reviews was evaluated using the AMSTAR 2 appraisal tool. The guidelines were formulated using the GRADE methodology by a multidisciplinary panel of experts. The diagnosis of AOM is based on acute clinical symptoms and otoscopic evidence; alternatively, the presence of otorrhea associated with spontaneous tympanic membrane perforation allows the AOM diagnosis. The diagnosis of AOM must be certain and the use of a pneumatic otoscope is of fundamental importance. As an alternative to the pneumatic otoscope, pediatricians can use a static otoscope and a tympanometer. To objectively establish the severity of the episode for the formulation of a correct treatment program, an AOM severity scoring system taking into account clinical signs and otoscopic findings was developed.The diagnosis of AOM is clinical and requires the introduction of specific medical training programs. The use of pneumatic otoscopes must be promoted, as they are not sufficiently commonly used in routine practice in Italy.

RESUMO

OBJECTIVES: To present the guidelines of the French Society of Otolaryngology-Head and Neck Surgery concerning the use of non-steroidal anti-inflammatory drugs (NSAIDs) in pediatric ENT infections. METHODS: Based on a critical analysis of the medical literature up to November 2016, a multidisciplinary workgroup of 11 practitioners wrote clinical practice guidelines. Levels of evidence were classified according to the GRADE (Grades of Recommendation, Assessment, Development and Evaluation) system: GRADE A, B, C or "expert opinion". The first version of the text was reworked by the workgroup following comments by the 22 members of the reading group. RESULTS: The main recommendations are: NSAIDs are indicated at analgesic doses (e.g. 20-30 mg/kg/day for ibuprofen) in combination with paracetamol (acetaminophen) in uncomplicated pediatric ENT infections (acute otitis media, tonsillitis, upper respiratory infections, and maxillary sinusitis) if: o pain is of medium intensity (visual analogue scale (VAS) score 3-5 or "Evaluation Enfant Douleur" (EVENDOL) child pain score 4-7) and insufficiently relieved by first-line paracetamol (residual VAS≥3 or EVENDOL≥4); o pain is moderate to intense (VAS 5-7 or EVENDOL 7-10). When combined, paracetamol and ibuprofen are ideally taken simultaneously every 6h. It is recommended: (1) o not to prescribe NSAIDs in severe or complicated pediatric ENT infections; (2) o to suspend NSAIDs treatment in case of unusual clinical presentation of the infection (duration or symptoms); (3) o not to prescribe NSAIDs for more than 72h.

RESUMO

Maslinic acid is a pentacyclic triterpene with a plethora of biological activities, including anti-inflammatory, antioxidant, antimicrobial, cardioprotective, and antitumor effects. New derivatives with improved properties and broad-spectrum activity can be obtained following structural changes of the compound. The present study was aimed to characterize a benzylamide derivative of maslinic acid-benzyl (2α, 3ß) 2,3-diacetoxy-olean-12-en-28-amide (EM2)-with respect to the anti-angiogenic and anti-inflammatory effects in two in vivo experimental models. Consequently, the compound showed good tolerability and lack of irritation in the chorioallantoic membrane assay with no impairment of the normal angiogenic process during the tested stages of development. In the acute ear inflammation murine model, application of EM2 induced a mild anti-inflammatory effect that was potentiated by the association with zinc chloride (ZnCl2). A decrease in dermal thickness of mice ears was observed when EM2 and ZnCl2 were applied separately or in combination. Moreover, hyalinization of the dermis appeared only when EM2 was associated with ZnCl2, strongly suggesting the role of their combination in wound healing.

RESUMO

BACKGROUND: Unilateral total facial palsy is a debilitating condition that can affect an individual's physical, social and emotional wellbeing. When this occurs bilaterally, the severity of impact is extreme, with significant cosmetic disfigurement and functional morbidity. A variety of facial reanimation techniques have been used for unilateral facial weakness of varying House-Brackmann grades, and these are also applicable in bilateral cases. In bilateral cases, it is difficult to gauge successful improvement in comparison to the contralateral side, which also is afflicted.Case reportThis paper presents our experience with a bilateral facial paralysis patient who had a complex otological history. The patient, who presented with bilateral debilitating grade VI facial palsy, achieved a good result from bilateral facial reanimation with sequential hypoglossal-facial anastomosis. This is considered a reasonable option in cases of bilateral facial paralysis.

RESUMO

OBJECTIVE: Ciprofloxacin resistance has been reported in 4.5% of patients with otorrhea and is increasing in prevalence. Due to ototoxicity, only fluoroquinolones are Food and Drug Administration approved for topical therapy in the middle ear. Furthermore, there is an assumption that antibiotic resistance is less relevant to topical therapy due to in vivo concentrations much higher than the minimum inhibitory concentration used to determine resistance. This study investigates ciprofloxacin-resistant infections and seeks to develop a better understanding of treatment options and outcomes. STUDY DESIGN: Retrospective review of 141 ciprofloxacin-resistant otologic infections. SETTING: Tertiary-care hospital. PATIENTS: Patients with culture-proven ciprofloxacin-resistant infections from 2008 to 2017. INTERVENTION(S): Antibiotic treatment with ciprofloxacin topical drops, ciprofloxacin plus oral antibiotics, and nonciprofloxacin therapy. MAIN OUTCOME MEASURE(S): Bacteriology for ciprofloxacin-resistant infections and treatment effectiveness of various therapies. RESULTS: Methicillin-resistant Staphylococcus aureus (33%), Corynebacterium striatum (19%), and non-Methicillin-resistant Staphylococcus aureus (11%) are the most frequent causes of ciprofloxacin-resistant infections. Topical ciprofloxacin monotherapy was successful in 2.7% of infections compared with a 64.7% success rate with the addition of an oral antibiotic (p < 0.001). Nonciprofloxacin drops are more effective with a 70% cure rate compared with the 2.7% of the ciprofloxacin drops p < 0.001. There was no difference in treatment efficacy when comparing nonciprofloxacin topical therapy (70% cure) to nonciprofloxacin topical therapy plus oral antibiotic (83% cure, p = 0.17). CONCLUSIONS: Using ciprofloxacin drops to treat ciprofloxacin-resistant bacteria is ineffective and patients do significantly better with alternative therapy. This finding supports the conclusion that high concentrations achieved in topical applications are not sufficient to overcome antibiotic resistance.
