Acute otitis media is a widespread disease affecting all ages. The introduction of antibiotics has led to a reduction in the incidence of complications from approx. 17% to 1%. Nevertheless, life-threatening complications still occur. The present paper describes the course and treatment of mastoiditis, petrositis and sepsis, as well as intracranial complications, i.e. meningitis, sigmoid sinus thrombosis, extradural abscess, subdural empyema, brain abscess and otitic hydrocephalus. The importance of antibiotic treatment for acute otitis media and the need to assess treatment outcomes are emphasised.

Brain abscess is a rare complication of staphylococcal bacteremia in infants. Here we present a case of a premature infant who developed multiple brain abscesses 12 weeks following an episode of inadequately treated Staphylococcus aureus sepsis. The abscess developed in the absence of trauma, prior surgery, cyanotic heart disease, or immune defect. The initial staphylococcal isolate exhibited identical pulsed-field gel electrophoresis pattern with that of the isolate cultured from abscess aspirate. The infant was successfully treated by surgical drainage and administration of antibiotics for 12 weeks, initially teicoplanin and meropenem followed by trimethoprim/sulfamethoxazole, without neurological or developmental sequelae. Staphylococcal bacteremia in neonates should be vigorously treated to prevent life-threatening complications.

Serious infections can result from wounds that are caused by bites from animals and humans. Organisms recovered from bite wounds generally originate from the oral cavity of the biting animal, as well as from the patient's skin flora. Anaerobes have been isolated from animal and human bite wound infections, especially those associated with abscess formation. In addition to local wound infections, common complications, such as lymphangitis, septic arthritis, tenosynovitis, and osteomyelitis, and uncommon complications, such as endocarditis, meningitis, brain abscess, and sepsis, may occur. Wound management includes proper local care and, when needed, antimicrobial therapy.

154 patients, who were hospitalized in M. Iashvili Children's central hospital in 1998-2005 were investigated. In 70 cases the diagnosis was neonatal bacterial meningitis, in 62 cases -- bacterial sepsis and neonatal meningitis and 22 cases patients were in control group with the diagnosis of neonatal bacterial sepsis. From base investigation group -132 patients were divided in two group, in which patients were united by the starting point of disease from the birth: first group included newborns with signs of disease on earlier stage (sings of the disease showed up during 24-72 hours from the birth); second group included newborns with later signs of disease (after 72 hours from the birth). Our conclusion is- outcome of bacterial meningitis depends on the starting point of disease. Meningitis which began earlier than 72 hours of life, characterized by severe prognosis. Mother's chronic infection diseases and brain injury of newborn are predictors of severe complications of neonatal bacterial meningitis. Such complications of bacterial meningitis as are: brain abscess, ventriculitis, neonatal seizures, coma and neutropenia, become predictors of severe latest outcome.

Melioidosis which is infection with Burkholderia pseudomallei, is an important cause of sepsis in India, southeast Asia and northern Australia. Mortality is high and treatment is problematic. Neurological melioidosis is unusual but meningoencephalitis, encephalomyelitis and brain microabscess can occur Dural sinus thrombosis is not an uncommon cerebrovascular disorder with various etiologies. Hypercoagulable state, pregnancy, dehydration, certain blood dyscrasia and contraceptive pills are common causes however meningitis and local head & neck infections may lead to this condition. Dural sinus thrombosis complicating septicemic melioidosis has never been reported. The authors report a 42-year-old Thai man suffering from septicemic melioidosis with dural sinus thrombosis. He had high fever, headache, left hemiparesis, focal seizure and increased intracranial pressure. Diabetes and mild alcoholic cirrhosis were diagnosed in this admission. CT scan, MRI brain and MRV revealed superior saggital sinus thrombosis with complicating venous infarction over right posterior parietal lobe. Hemoculture demonstrated Burkholderia pseudomallei and CSF was acellular Investigations for causes of dural sinus thrombosis were all negative. This patient gradually improved after treatment with ceftazidime, antiepileptic drug and heparin without clinical recurrence. Neuromelioidosis is a rare syndrome that may present as brain abscess, encephalitis or meningoencephalitis. The authors report dural sinus thrombosis associated with septicemic melioidosis. The authors' hypothesis of venous thrombosis in the presented case is sepsis induced hypercoagulable state. Physicians should be aware of cerebral venous thrombosis in case of suspicious melioidosis with neurological involvement. Prompt treatment with intravenous heparin and antibiotic is potentially effective.

Purulent fluid collections, including brain abscess and subdural empyema, are exceedingly rare in association with meningococcal meningitis. We present a 5-month-old infant with meningococcal meningitis and sepsis complicated by an intracerebral abscess.

Brain abscess results from local or metastatic septic spread to the brain. The primary infectious site is often undetected, more commonly so when it is distant. Unlike pediatric congenital heart disease, minor intracardiac right-to-left shunting due to patent foramen ovale has not been appreciated as a cause of brain abscess in adults. Here we present a case of brain abscess associated with a patent foramen ovale in a 53-year old man with dental-gingival sepsis treated in the intensive care unit. Based on this case and the relevant literature we suggest a link between a silent patent foramen ovale, paradoxic pathogen dissemination to the brain, and development of brain abscess.

Enterobacter sakazakii is an opportunistic pathogen associated with contaminated powdered infant formula and a rare cause of Gram-negative sepsis that can develop into meningitis and brain abscess formation in neonates. Bacterial pathogenesis remains to be fully elucidated. In this study, the host inflammatory response was evaluated following intracranial inoculation of Ent. sakazakii into infant rats. Infiltrating macrophages and neutrophils composed multiple inflammatory foci and contained phagocytosed bacteria. Several genotypically distinct Ent. sakazakii strains (16S cluster groups 1-4) were shown to invade rat capillary endothelial brain cells (rBCEC4) in vitro. Further, the persistence of Ent. sakazakii in macrophages varied between strains. The presence of putative sod genes and SOD activity may influence the survival of acidic conditions and macrophage oxidase and contribute to Ent. sakazakii intracellular persistence. The influence of macrophage uptake of Ent. sakazakii on immunoregulatory cytokine expression was assessed by ELISA. This demonstrated that the IL-10/IL-12 ratio is high after 24 h. This is suggestive of a type 2 immune response which is inefficient in fighting intracellular infections. These findings may help explain how the diversity in virulence traits among Ent. sakazakii isolates and an unsuccessful immune response contribute to the opportunistic nature of this infection.

Capnocytophaga canimorsus has been recognized as an opportunistic pathogen causing systemic infections in immunocompromised individuals. It is part of the normal oral flora of the dog, and can be responsible for localized wound infections in humans in consequence of bites. This microorganism causes also septicemia, meningitis, endocarditis, ocular infections and rarely brain abscess. We describe the case of an immunocompetent 28-year-old male with temporal brain abscess from Capnocytophaga canimorsus secondary to dog's bite.

Brain abscess is a rare but very dangerous neurosurgical lesion. Prompt diagnosis and emergency surgical evacuation are the hallmarks of therapy. Brain abscess following ischemic and hemorrhagic stroke is a rare entity. These cases are often preceded by episodes of bacteremia, sepsis, and local infection. The authors report the case of a 30-year-old woman who presented with a cerebral abscess at the site of a recent intraparenchymal hemorrhage.
