The Difference

Middle ear infection occurs when fluid accumulate in middle ear as a result of inflammatory response to viral or bacterial infection. Infections may spread from the middle ear, resulting in a subperiosteal collection beneath the temporal muscle. Luc abscess is a rare complication of otitis media. The difference of this complication with other extracranial abscesses relating to otitis media is, it may not be associated with mastoid bone involvement. Therefore, it is defined as benign complication of otitis media. Here, we report a case of 10-month-old baby boy diagnosed with Luc abscess with mastoid involvement.

The Difference

Introduction. Middle ear infection affects mostly infants and children, associated with elevatedlevel of S. mutans, which increases the chances of developing caries.Aim. To evaluate the difference in level of Streptococcus mutans between normal children & children affected by middle ear infection.Method. This descriptive study was carried out on 120 children aged 5 years and younger. They were selected randomly from schools and medical hospitals. S. mutans was counted from saliva sample and a questionnaire was given to be filled by their parents about the feeding method, pattern and specific childhood illness.Result. Out of 120 children examined, 62 were boys and 58 were girls. Mean CFU in middle ear infection group was 5.60+9.53, whereas in children with no middle ear infection it was 1.70+3.34. Unpaired ‘t’ test revealed statistically significant difference among the two groups (p value = 0.001).Conclusion. S. mutans count was comparatively higher in children having middle ear infection rather than non-infected children, which may cause dental caries in the future.

Objectives:     To present a case of vocal cord paralysis and dysphagia developing in Gradenigo syndrome and to discuss its clinical presentation, differential diagnosis and therapeutic approach.   Methods:             Design: Case Report             Setting:  Tertiary Government Hospital             Patient: One   Results:  A 54-year-old lady was admitted with a six month history of left-sided otorrhea, cheek and jaw pain, three months otalgia, and recent-onset hoarseness, dysphagia and diplopia on a background of mastoidectomy at age 6. Otoscopy revealed granulation tissue and chlolesteatoma occupying the left external auditory canal. There was left vocal cord paralysis with pooling of saliva in the pyriform sinus, left lateral gaze paralysis, and left facial nerve paralysis. CT scan revealed sclerosis of the left petrous apex and leptomeningeal enhancement on the left temporal lobe. Chronic suppurative otitis media with cholesteatoma and Gradenigo syndrome was diagnosed, and canal wall down mastoidectomy was performed Postoperatively, the otalgia and pain over the left jaw diminished in intensity while hoarseness and left lateral gaze palsy remained.   Conclusion: Gradenigo syndrome is known for its triad of retro-orbital pain, lateral gaze paralysis, and chronic middle ear infection due to petrous apicitis. Although rare, vocal cord paralysis and dysphagia may develop when infection traverses and encroaches on the jugular foramen where cranial nerves IX, X, and XI are lodged.  Knowledge of the syndrome should not be limited or confined to the classic triad.  Practicing ear specialists should be vigilant and cognizant of the clinical manifestations and sequelae of chronic middle ear infection. Prompt surgical intervention is crucial while resolution of the disease may vary for different individuals.   Keywords: Chronic otitis media, Gradenigo syndrome, vocal cord paralysis, petrous apicitis

The seal of the implanted round window membrane to resist Streptococcus pyogenes invasion from the middle ear was investigated in 12 cats. Results showed that the implanted round window membrane is able to form a barrier for S pyogenes starting 1 week postimplantation. Under normal conditions S pyogenes did not pass through the round window membrane, nor through the gap that existed between the membrane and the prosthesis. Mechanical disruption of the round window seal, however, and severe inflammatory response to S pyogenes caused the infection to extend into the inner ear.

Patient Morbidity

Middle ear infection, or acute otitis media (AOM), is a common condition encountered in primary care. Unfortunately, the diagnosis and sequelae of AOM can be overlooked, leading to significant patient morbidity. This article aims to raise awareness of AOM and highlights the relevant anatomy, epidemiology and aetiology. We discuss prevention, diagnosis and management of AOM in primary care, the recognition of complications and when to refer to secondary care.

Middle Ear Infection

ABSTRACT Treatment of acute otitis media (AOM) with azithromycin results in apparent clinical success, but tympanocentesis performed 4 to 6 days after initiation of therapy in children with nontypeable Haemophilus influenzae (NTHI) recovered from initial middle ear cultures demonstrates persistence of infection in more than 50% of episodes. We sought to determine the effect of azithromycin at different doses on the density of middle ear infection due to NTHI to provide additional understanding of this dichotomy between clinical and microbiologic outcome measures in AOM. In a chinchilla model of experimental otitis media (EOM), animals treated with placebo were compared to animals receiving a single daily dose 30 or 120 mg of azithromycin per kg of body weight per day for 5 days. Microbiologic outcome was assessed by obtaining quantitative cultures from the middle ear during a 5-day course and for 1 week following therapy. Azithromycin concentrations were measured to ascertain whether a concentration-dependent effect was present. Azithromycin at 30 and 120 mg/kg/day demonstrated a dose-dependent effect on the quantitative assessment of middle ear infection due to NTHI. A 30-mg/kg dose of azithromycin daily resulted in levels in serum and areas under the serum concentration-time curve at 24 h comparable to published data obtained with children given azithromycin at 5 to 10 mg/kg in multiday regimens. Increased doses of azithromycin (120 mg/kg) achieved 2.5- to 4-fold-higher levels in serum and 3- to 6-fold-higher total levels and levels in extracellular middle ear fluid as well as more rapid reduction in bacterial density and a greater proportion of middle ears with complete sterilization than either placebo or the 30-mg/kg/day regimen.
