ABSTRACT
Se realizó un estudio descriptivo de serie de casos, de 42 pacientes con otitis externa maligna, atendidos en el Servicio de Otorrinolaringología del Hospital Provincial Docente Clinicoquirúrgico Saturnino Lora de la provincia de Santiago de Cuba desde enero de 2002 hasta diciembre de 2014 y tratados básicamente con ciprofloxacina, a fin de caracterizarles clínica, epidemiológica y terapéuticamente, así como determinar su evolución clínica con el tratamiento indicado. También se incluyó un segundo grupo de 29 integrantes con la misma afección, quienes durante esos 12 años recibieron otros antibióticos y no la citada quinolona, tratados igualmente en dicho Servicio durante el período señalado. Entre los principales resultados sobresalió el predominio del grupo etario de 55-64 años (30,6 por ciento) en los que se utilizó ciprofloxacino y de 75 y más (74,8 por ciento) en los que se indicaron otros antimicrobianos; del tiempo de evolución de la diabetes mellitus de 0-10 años en 24 (57,1 por ciento) de quienes recibieron ciprofloxacino y en 14 (48,2 por ciento) de aquellos que no la consumieron y de la Pseudomonas aeruginosa como el germen más frecuentemente aislado. La evolución de los pacientes fue favorable, independientemente del tratamiento antimicrobiano prescrito, pero todos los tratados con ciprofloxacina egresaron en menos de 30 días mejorados o curados. Se concluyó que la edad avanzada favorece la aparición de la otitis externa maligna, sin importar el tiempo de evolución de la diabetes mellitus
A descriptive, serial cases study, of 42 patients with malignant external otitis was carried out. They were assisted in the Otolaryngology Service of Saturnino Lora Torres Teaching Clinical Surgical Provincial Hospital in Santiago de Cuba from January, 2002 to December, 2014 and treated basically with ciprofloxacin, in order to characterize them clinical, epidemiological and therapeutically, as well as to determine their clinical course with the suitable treatment. A second group of 29 members with the same disorder was also included who received other antibiotics during those 12 years, treated in this Service during that period. Among the main results there was a prevalence of the 55-64 years age group (30.6 percent) in which ciprofloxacin was used and over 75 years (74.8 percent) in which other antimicrobians were indicated; of the time in the diabetes mellitus course 0-10 years in 24 (57.1 percent) of those who received ciprofloxacin and in 14 (48.2 percent) of those that didn't consume it and of the Pseudomonas aeruginosa as the most frequently isolated germ. The patients had a favorable clinical course, no matter the antimicrobian prescribed treatment, but all the patients treated with ciprofloxacin got better or were cured and were discharged in less than 30 days. It was concluded that the advanced age favors the emergence of the malignant external otitis, no matter the time of the diabetes mellitus course

Skull-base osteomyelitis is a rare disease affecting the medulla of the temporal, sphenoid, and occipital bones. In general, it occurs due to external ear canal infections caused by malignant external otitis. Skull-base osteomyelitis usually affects elderly diabetic patients. The patient, a 58-year-old man, was referred for evaluation and management of the left jaw. Clinical examination of the patient revealed pain in the left jaw and mouth-opening deflection to the left. The maximum active mouth opening was measured to about 27 mm. Panoramic, CT, and CBCT revealed bone resorption patterns in the left condyle. Through control of diabetes, continued pharmacological treatment, arthrocentesis, and occlusal stabilization appliance therapy were carried out. The extent of active mouth opening was increased to 45 mm, and pain in the left jaw joint was alleviated. This was a case wherein complications caused by failure to control diabetes induced skull-base osteomyelitis. There is a need for continued discussion about the advantages and disadvantages of arthrocentesis with lavage for patients with skull-base osteomyelitis and other treatment options.

Objective To explore the value of computed tomography (CT)and magnetic resonance imaging (MRI)in the diagno-sis and delineation of the extent of malignant external otitis (MEO).Methods Clinical manifestations and imaging features of 10 pa-tients with definite diagnosis of MEO were collected and analyzed.Plain and contrast-enhanced CT of the ear were performed on all 10 patients,of which 6 patients also received MRI scans.Results Abnormal soft tissue opacity within the external auditory canal and involvement of surrounding structures were found in all 10 patients.Bone erosion of the external auditory canal was showed in 7 pa-tients.Other CT findings included bone erosion of skull base and intracranial involvement.Abnormal soft tissue of the external audi-tory canal,effusion in the mastoid cavity and medullary abnormalities were showed very well on MR images in 6 patients while the cortical bone erosion was not well showed.Conclusion Imaging features of the lesions in the external auditory canal,bone erosion of skull base and intracranial involvement play crucial roles in the diagnosis and delineation of the extent of the lesion in patients with MEO.
ABSTRACT
Pichia ohmeri is a rare fungal pathogen for human infection. To date, only 5 cases of P. ohmeri infection have been reported including fungemia, disseminated infection and peritonitis. We report the first case of malignant external otitis and mastoid osteomyelitis caused by P. ohmeri. The patient had a long history of diabetes, hypertension and arrrhythmia. The patient was admitted to the hospital because of otorrhea, otalgia and hearing difficulty for 3 months. Internal auditory canal MRI showed osteomyelitis of left mastoid bone and skull base. Culture of ear discharge and bone biopsy specimen grew P. ohmeri. The patient had been treated with amphotericin-B followed by fluconazole.
