[A case of acute purulent otitis media complicated by atypical mastoiditis on the background of an unverified HIV infection]. / Sluchai ostrogo gnoinogo srednego otita, oslozhnennogo atipichnym mastoiditom, na fone neverifitsirovannoi VICh-infektsii.

According to the literature, acute otitis media is complicated by mastoiditis in 0.15-1% of cases. In turn, mastoiditis can be complicated by meningitis, encephalitis, abscess of temporal lobe of brain and cerebellum, epidural and subdural abscesses, facial nerve paresis, labyrinthitis, phlegmon of soft tissues of neck, as well as subperiosteal abscess, which makes 7% in the structure of mastoiditis complications. Nowadays, when doctors have a wide range of antibacterial preparations at their disposal, a complicated course of acute otitis media and further mastoiditis is caused both by an aggressive atypical infectious agent and immunocompromised status of a patient. The article deals with a clinical case of a prolonged course of acute otitis media complicated by mastoiditis and subperiosteal abscess against the background of outpatient courses of antibacterial therapy. The examination revealed an atypical pathogen of otitis media Pseudomonas aeruginosa and HIV-positive status of the patient, previously unknown. Timely surgical intervention and the right combination of antibacterial drugs, meropenem and ciprofloxacin, prevented the development of intracranial and septic complications, despite the presence of multiple foci of bone destruction of the mastoid process and temporal bone pyramid, bordering the middle fossa and sigmoid sinus, according to multispiral head computed tomography. As a part of additional examination in the Center for AIDS and Infectious Diseases Prevention and Control, the patient was diagnosed with HIV infection, clinical stage 4C, progressing phase on the background of absence of antiretroviral therapy, and the necessary amount of treatment was prescribed.

[Clinical observation of a patient with bilateral tuberculous otitis media developing against the background of HIV infection]. / Klinicheskoe nablyudenie patsienta s dvustoronnim srednim tuberkuleznym otitom, razvivshimsya na fone VICh-infektsii.

The lesion of middle ear as a variant of clinical manifestation of secondary tuberculosis, according to international scientific literature, is a rare condition. However, in terms of real clinical practice, the proportion of this pathology should not be underestimated due to the wide spread of tuberculosis infection among the population of developing countries, including the Russian Federation. One of the risk factors for the systemic spread of mycobacterial flora is a concomitant HIV infection, which often acts as an opportunistic pathological agent for tuberculosis. The treatment of such a state is always challenging because of the high aggressiveness of bacteria and the low immunological resistance of the patient. This article presents a clinical case of bilateral tuberculosis otitis media, which was a manifestation of tuberculosis infection that developed on the background of HIV infection.

[The specific clinical features of otogenic intracranial complications: the current views].

The objective of the present study was to elucidate the specific clinical features of otogenic intracranial complications (ICC) encountered in the current otorhinolaryngological practice. The work is based on the results of the retrospective analysis of 106 adult patients presenting with otogenic intracranial complications admitted for the treatment to multidisciplinary clinics of Sankt-Peterburg and Krasnoyarsk. Forty six (42.5%) patients presented with acute otitis media. 90% of them had suppurative destructive mastoiditis. In sixty (56.6%) patients, chronic suppurative otitis media (epitympanophonia) was associated with the extensive destructive process spreading toward dura mater of the medial and posterior cranial fossae and onto the sigmoid sinus. The prevalence of intracranial complications among the adult patients suffering from suppurative otitis media and treated in the otorhinolaryngological clinics amounted to 3.17%. The overall structure of otogenic intracranial complications was as follows: meningitis 42.5%, brain and cerebellum abscess 24.5%, suppurative meningoencephalitis 19.8%, sinus thrombosis 5.7%, epidural and subdural empyemas 4.7%, the combined suppurative brain lesions 2.8%. Systemic inflammatory response syndrome (sepsis) was diagnosed in 33 (31%) patients with otogenic ICC. The high intrahospital mortality rate among the patients with this condition (20.8%) is emphasized. The main causes of the fatal outcome in the patients with otogenic intracranial complications are supposed to be brain oedema with the concomitant development of dyslocation syndrome and sepsis.
