RESUMEN

ABSTRACT We describe an unusual case of Nocardia spp scleritis in a health girl resistant to topical fourth-generation fluoroquinolones. Clinically, there was only partial response of the scleritis to initial therapy. Treatment was changed to meropenem intravenously and topical amikacin. Following several weeks of antibiotic treatment, the patient's infection resolved but her vision was reduced to no light perception. Nocardia asteroides must be considered as a possible agent in cases of necrotizing scleritis in patients without a clear source. Antibiotic sensitivity testing has a definitive role in view of the resistance to these new medications.


RESUMO Nós descrevemos um raro caso de esclerite por Nocardia spp em uma criança sadia resistente a utilização tópica de fluorquinolona de quarta-geração. Clinicamente, a paciente apresentou apenas uma resposta parcial do quadro de esclerite a terapêutica inicial. O tratamento foi então modificado para meropenem intravenoso e amicacina tópica. Após várias semanas de tratamento com antibiótico, o quadro infeccioso regrediu porém a visao da pacientes evoluiu para perda da percepção luminosa. Em casos de esclerite necrotizante em pacientes sem fatores de risco aparente é necessário considerer a Nocardia Asteroides como possível agente causador. Os testes de sensibilidade medicamentosa apresentam importância significativa em virtude do aparecimento de resistência aos novos medicamentos.

RESUMEN

Infectious scleritis by Pseudomonas aeruginosa is a well-known vision-threatening disease. In particular, scleral trauma following pterygium surgery may increase the risk of sclera inflammation. Surgical debridement and repair is necessary in patients who do not respond to medical treatments, such as topical and intravenous antibiotics. We reports herein the effectiveness of an autologous perichondrium conchal cartilage graft for infectious scleritis caused by Pseudomonas aeruginosa. This procedure was performed on four eyes of four patients with infectious scleritis who had previously undergone pterygium surgery at Gyeongsang National University Hospital (GNUH), Jinju, Korea from December 2011 to May 2012. Pseudomonas aeruginosa was identified in cultures of necrotic scleral lesion before surgery. The conchal cartilage perichondrium graft was transplanted, and a conjunctival flap was created on the scleral lesion. The autologous perichondrium conchal cartilage graft was successful and visual outcome was stable in all patients, with no reports of graft failure or infection recurrence. In conclusion, autologous perichondrium conchal cartilage graft may be effective in surgical management of Pseudomonal infectious scleritis when non-surgical medical treatment is ineffective. Further studies in larger, diverse populations are warranted to establish the effectiveness of the procedure.

RESUMEN

Mycobacteria other than tuberculosis (MOTT) have a low incidence as pathogens in human pathology. The most frequent clinical expression is the disseminated disease in subjects with compromised cellular immunity. Bacteriological characteristics in culture can generate confusion with other pathogens, which delays the appropriate diagnosis and treatment. We present a case of a disseminated infection due to Mycobacterium chelonae with scleritis, spondylodiscitis and spinal epidural abscess in a man with a medical background of cellular immunity deficit induced by therapeutic drugs. The antibiotic scheme of twenty-one weeks, during the follow-up period, controlled the infection, however, the optimum duration of treatment has not been established.

RESUMEN

We report the history and clinical presentation of an 88-year-old female with Fuchs dystrophy who developed an acute anterior necrotizing scleritis in her left eye 23 months after an uncomplicated combined penetrating keratoplasty and phacoemulsification with intraocular lens implantation which progressed to slceral perforation with uveal prolapses. The patient underwent a complete systemic work-up for both autoimmune and infectious causes of scleritis. Surgical specimens of the area of scleral perforation were sent for histology and microbiologic studies. Analysis of surgical specimens revealed the presence of culture-proven Nocardia asteroides as a causative agent for the patient's scleral perforation. Results of her systemic autoimmune work-up were not conclusive. Successful treatment with tectonic scleral reinforcement with donor corneal tissue and preserved pericardium, oral and topical trimethoprim-sulfamethoxazole and topical amikacin salvaged the globe and increased vision. The patient's final best-corrected visual acuity sixteen months after her last operation remains 20/70. Prompt surgical intervention with submission of appropriate specimens for pathological diagnosis and microbiology, along with consultation with rheumatologic and infectious disease specialists, are mandatory to minimize visual loss in cases of suspected infectious necrotizing scleritis.


Relato de caso de esclerite necrosante aguda, evoluindo para perfuração escleral com prolapso uveal, 23 meses após procedimento de ceratoplastia penetrante e facoemulsificação com implante de lente intra-ocular no olho esquerdo sem intercorrências.A paciente foi submetida à avaliação completa auto-imune para esclerite. Biópsia da área de perfuração escleral foi encaminhada para avaliação patológica e microbiológica. Análise de material cirúrgico revelou presença de cultura proveniente de Nocardia asteroides como agente causal da perfuração escleral. Resultados de exames do sistema auto-imune não foram conclusivos. Tratamento foi um sucesso com reforço escleral tectônico do tecido corneano doador, utilização de pericárdio preservado, associado ao uso sistêmico e tópico de sulfametoxazol-trimetropina e amicacina colírio. Apresentou melhora visual após o tratamento e a melhor correção visual final, 16 meses após o último procedimento cirúrgico foi de 20/70. Intervenção cirúrgica precoce, análise patológica e microbiológica do material, associados a consulta a especialistas na área de doenças infecciosas e reumatologia, são primordiais para minimizar perda visual em casos de suspeitas de esclerite infecciosa necrosante.
