Anterior Uveitis Due to Intracameral Moxifloxacin: A Case Report.

Purpose: To report a case of a drug-induced anterior uveitis secondary to the use ofintracameral moxifloxacin.Case report: A 64-year-old Colombian male patient presented with severe ocular pain and photophobia in his left eye 15 days after cataract surgery. In the ophthalmology and glaucoma specialist evaluation, pigment dispersion in the anterior chamber and camerular angle, severe anterior segment inflammation, and elevated intraocular pressure were observed. Poor response to treatment for a suspected viral origin and exclusion of other possible etiologies, led to the conclusion of intracameral moxifloxacin induced anterior uveitis.Conclusion and importance: We present the second published case worldwide about anterior uveitis secondary to intracameral moxifloxacin, which may rarely cause hypertensive uveitis that may be confused with viral uveitis. This provides evidence on the importance of postoperative follow-up by the surgeon for an early referral and treatment of these cases.

Factores relacionados con el control exitoso de un brote por Klebsiella pneumoniae productora de KPC-2 en una unidad de cuidado intensivo en Bogotá, Colombia / Factors related to successful control of an outbreak by Klebsiella pneumonia -producing KPC-2 in an intensive care unit in Bogotá, Colombia

La resistencia a carbapenémicos en Klebsiella pneumoniae ha aumentado de manera considerable, incrementando las tasas de morbimortalidad. El objetivo de este trabajo fue describir las características epidemiológicas, microbiológicas y las medidas de intervención que permitieron el control exitoso de un brote de Klebsiella pneumoniae productora de KPC-2. Métodos: El estudio se realizó en 2 periodos: el primero durante el brote, con instauración de un protocolo de medidas de intervención; y el segundo, de seguimiento posbrote. Se realizaron pruebas de identificación y susceptibilidad por sistema automatizado, tamización de carbapenemasas por test de Hodge modificado, PCR para detección de los genes bla KPC, bla KPC-2, NDM-1 y estudio de clonalidad por electroforesis de campos pulsados. Resultados: Durante el brote, se identificaron 18 aislamientos de Klebsiella pneumoniae productora de KPC en 11 pacientes. Tres casos fueron confirmados como infección intrahospitalaria. La técnica de PCR reveló la presencia del gen bla KPC en 21 de 22 aislamientos (pacientes y medio ambiente) y se identificó la presencia de un clon con una similitud superior al 75%. En el periodo posbrote los cultivos ambientales y de búsqueda de colonizados fueron negativos. Discusión: Se evidenció un control exitoso del brote producido por un clon. La implementación de un protocolo de intervención y la monitorización de su cumplimiento, la comunicación efectiva y el trabajo en equipo fueron indispensables para evitar su propagación y evitar un comportamiento endémico posbrote.

The considerable increase in carbapenem-resistant Klebsiella pneumoniae has caused an increase in mortality and morbidity rates. The aim of this study was to describe its epidemiological and microbiological characteristics and the intervention measures that controlled an outbreak caused by K. pneumoniae- producing KPC-2 B-lactamase. Methods: The study was divided into 2 periods: the first during the outbreak with the implementation of a bundle and the second a post-outbreak surveillance. We performed tests for identification and susceptibility by using an automated system, screening carbapenemases by the Modified-Hodge test, bla KPC, bla KPC-2 and NDM-1 identification by PCR and clonal relationship characterisation by PFGE. Results: During the outbreak, there were 18 isolates of Klebsiella pneumoniae -producing KPC- 2 in 11 patients. Three cases were confirmed as hospital-acquired infection. Of 22 isolates, 21 were positive to bla KPC by PCR (samples from patients and environment) and a clone was identified with a similarity of greater than 75%. During the post-outbreak surveillance, we did not find any new positive cultures from surfaces and there were no new colonisations. Discussion: This was a successful control of an outbreak produced by a clone. The implementation of a bundle and a subsequent surveillance to monitor its fulfilment, effective communication and teamwork were crucial to inhibit propagation of the infection and to prevent an endemic behaviour post-outbreak.

Cytokine gene polymorphisms in Colombian patients with different clinical presentations of tuberculosis.

Tuberculosis (TB) has different clinical presentations. Pulmonary TB affects only the lungs and exhibits variable anti-mycobacterial immune responses. Pleural TB is a localized disease with a strong immune response. Miliary TB is a disseminated form with poor immune response. Cytokines play a pivotal role in anti-mycobacterial response and may determine the type of TB. Thus, gene polymorphisms associated with cytokine production may be associated with clinical presentations of TB. In this study, 54 tuberculin-negative healthy controls, 81 tuberculin-positive healthy controls, 140 patients with pulmonary TB, 30 with pleural TB and 20 with miliary TB were studied. Single nucleotide polymorphisms were typed for tumour necrosis factor-alpha, interferon-gamma (IFN-gamma), transforming growth factor-beta1, interleukin-10 (IL-10) and interleukin-6 by sequence-specific primer polymerase chain reaction (SSP-PCR). Allelic, genotypic and haplotypic associations with clinical forms of TB were evaluated. IL-10 -1082 A/A genotype and IFNgamma+874 T allele were associated with pleural TB. Seventy-five extended genotypes were found; two differed between patients and controls, and two between groups of patients. Results suggest that IL-10 low-producer polymorphism and IFN-gamma high-producer polymorphism are associated with pleural TB.

Drug resistance has become a major problem in the treatment of tuberculosis. Pulmonary resection in combination with chemotherapy appears to be an effective measure for the treatment of multi-drug resistant pulmonary tuberculosis. A retrospective review was performed of the medical and laboratory findings of 28 patients with multi-drug resistant tuberculosis who underwent pulmonary resection for pulmonary tuberculosis between January 1990 and December 2000 at La Maria Hospital, Medellín. Twenty-one of them had medical therapy before surgery; 14 patients underwent upper lobectomy and 10 patients pneumonectomy). The AFB negative sputum conversion rate was 88.9% (25/27) after surgery, during an average of 6 weeks. Bacteriological relapses were confirmed in 6 of 27, 4 of these 6 had AFB negative sputum. Twenty-eight patients had medical therapy after surgery. For selected patients, pulmonary resection in combination with chemotherapy should be considered an effective measure for treatment of multi-drug resistant pulmonary tuberculosis.

Cirugía en tuberculosis pulmonar multirresistente

La aparición de Mycobacterium tuberculosis multirresistente constituye un serio problema para el control de la tuberculosis, por lo que se ha considerado que la resección quirúrgica del tejido pulmonar afectado, junto con el tratamiento médico adecuado, podría proporcionar la curación en algunos pacientes con tuberculosis pulmonar multiresistente. En este estudio de tipo descriptivo, retrospectivo, se evaluaron los resultados clínicos y bacteriológicos de la resección quirúrgica en un grupo seleccionado de pacientes con tuberculosis pulmonar multirresistente. Se revisaron las historias clínicas del Hospital La María de Medellín de 1990 a 2000, y se encontró que se habían sometido a cirugía 73 pacientes con diagnóstico de tuberculosis durante este periodo, 28 de los cuales tenían como indicación quirúrgica tuberculosis multirresistente (resistencia a isoniacida y rifampicina), 21 de los cuales habían recibido tratamiento prequirúrgico. En 14 (50%) se había practicado lobectomía superior y en 10 (36,7%), neumonectomía. Todos recibieron tratamiento posquirúrgico por un periodo promedio de 12,5 meses. En 88,9% (25/27) de los casos, la baciloscopia fue negativa después de 6 semanas de la cirugía y hasta finalizar el tratamiento antituberculoso; 6 pacientes presentaron nuevamente baciloscopia positiva, aunque 4 tuvieron baciloscopia negativa después de un nuevo esquema de tratamiento. Los pacientes, de acuerdo con las normas del ministerio, fueron seguidos con baciloscopia mensual y no con cultivo como es lo indicado en los casos de multirresistencia. La cirugía junto con el tratamiento médico adecuado constituye una buena alternativa de curación para algunos pacientes con tuberculosis pulmonar multirresistente.
