Fulminant endogenous panophthalmitis caused by Clostridium septicum infection / Panoftalmite endógena fulminante por infecção por Clostridium septicum

ABSTRACT We report an unusual case of fulminant endogenous Clostridium septicum panophthalmitis. A 74-year-old male patient presented with sudden amaurosis in the right eye, which in a few hours, evolved into an orbital cellulitis, endophthalmitis, anterior segment ischemia, and secondary perforation of the eye. A complete diagnostic study, which included cranial and orbital contrast-enhanced computed tomography scan, contrast-enhanced magnetic resonance imaging, blood cultures, and complete blood work, were performed. No causal agent was identified. Clostridium septicum infection caused fulminant gaseous panophthalmitis. Despite broad-spectrum antibiotic treatment, evisceration of the eyeball was necessary. The extension study showed a colon adenocarcinoma as the origin of the infection. Clostridium septicum panophthalmitis is a rare but aggressive orbital infection. This infection warrants the identification of a neoplastic process in the gastrointestinal tract in many cases not previously described.

RESUMO Este é o relato de um caso incomum de panoftalmite endógena fulminante por Clostridium septicum. Um paciente do sexo masculino, 74 anos, apresentou amaurose súbita no olho direito, que em poucas horas evoluiu para celulite orbitária, endoftalmite, isquemia do segmento anterior e perfuração secundária do olho. Foi realizado um estudo diagnóstico completo, que incluiu uma tomografia computadorizada com contraste cranial e orbital, um exame de ressonância magnética, hemocultura e hemograma completo. Nenhum agente causal foi identificado. A infecção por Clostridium septicum causou uma panoftalmite gasosa fulminante. Apesar do tratamento com antibióticos de amplo espectro, foi necessário eviscerar o globo ocular. O estudo de seguimento mostrou um adenocarcinoma de cólon como a origem da infecção. A panoftalmite por Clostridium septicum é um tipo raro, mas muito agressivo de infecção orbitária. Essa infecção deve sugerir a busca por um processo neoplásico no trato gastrointestinal, em muitos casos não diagnosticado anteriormente.

Versatilidad del colgajo microvascularizado antebraquial radial en la reconstrucción de cabeza y cuello. Una serie de 58 casos / Versatility of the radial forearm free flap in head and neck reconstruction. A study of 58 case

INTRODUCCIÓN: El colgajo microvascularizado antebraquial radial (CMAR) es una herramienta ampliamente utilizada en la cirugía reconstructiva de cabeza y cuello. Destaca por ser un colgajo relativamente sencillo de obtener, versátil y con características que permiten la reconstrucción de defectos complejos de la cabeza y el cuello. El objetivo del estudio es presentar nuestros resultados en la reconstrucción con CMAR de defectos que asentaban en el área de la cabeza y el cuello. MATERIAL Y MÉTODOS: Estudio retrospectivo, observacional y analítico en el que se incluyen 58 casos de intervenciones con CMAR realizadas entre enero de 2002 y julio de 2019. Los datos estudiados fueron la edad y el sexo del paciente, la localización del tumor, el tipo histológico, la radioterapia previa, el número de anastomosis venosas realizadas en la cirugía y la temperatura corporal en el postoperatorio inmediato, a las 24 y a las 48 h de la cirugía. RESULTADOS: El porcentaje de CMAR viables fue del 82,8%. Ninguna de las variables analizadas parece ser un factor de riesgo para el fallo del colgajo. La causa más frecuente de fallo del colgajo es la trombosis venosa. CONCLUSIONES: Los colgajos microvascularizados tienen un papel destacado en la cirugía reconstructiva, siendo el CMAR uno de los más interesantes para la reconstrucción de cabeza y cuello. Constituye una herramienta muy versátil que permite la reconstrucción de gran cantidad de localizaciones en las que trabaja el cirujano de cabeza y cuello

INTRODUCTION: The radial forearm free flap (RFFF) is a widely used tool in head and neck reconstructive surgery. It stands out as a relatively simple flap to achieve; it is versatile and has features that enable the reconstruction of complex head and neck defects. The aim of the study was to present our results using the RFFF in the reconstruction of seated defects in the head and neck area. MATERIAL AND METHODS: A retrospective, observational and analytical study that included 58 cases of RFFF interventions, performed between January 2002 and July 2019. The data studied were the age and sex of the patients, location of the tumour, histological type, previous radiation therapy, number of venous anastomoses performed in the surgery and body temperature in the immediate postoperative period, at 24 and 48hours following surgery. RESULTS: The percentage of viable RFFF was 82.8%. None of the variables analysed appear to be a risk factor for flap failure. The most frequent cause of flap failure was venous thrombosis. CONCLUSIONS: Microvascularised flaps play an important role in reconstructive surgery, being the RFFF one of the most interesting for head and neck reconstruction. It is a very versatile tool that allows the reconstruction of many of the sites where the head and neck surgeon operates

The contribution of telemedicine to hepatitis C elimination in a correctional facility

Background: micro-elimination has been recently proposed as an efficient strategy to achieve global hepatitis C virus (HCV) elimination. The Spanish Health Ministry Strategic Plan for hepatitis C infection highlighted intervention in prisons as a priority action. However, there are important barriers associated with the specialized care provision to the penitentiary population. Aims: to assess the contribution of telemedicine for HCV elimination in a correctional facility in Spain. Methods: an open label program of HCV elimination via telemedicine was started on February 3rd, 2015 in a large penitentiary of 1,200 inmates, as an alternative to referring patients to specialists. An anonymous satisfaction survey was performed among a random sample of inmates and all participating doctors. Results: the prevalence of HCV viremia prior to program initiation was 12.4%. One hundred and thirty-one patients received DAA HCV treatment during the period 2015-2018; 42.74% had a HCV-HIV co-infection. Overall, 97% achieved a sustained virological response (SVR). A second regime of DAA successfully rescued non-responder patients and the HCV prevalence was zero at the end of the program. Satisfaction was high or very high according to 67% of inmates and all participating doctors. Conclusion: telemedicine is an effective tool for HCV elimination in penitentiary correctional facilities where referral to specialists is difficult. The extensive use of this technology should be recommended in this setting in order to facilitate equitable access to specialized care

Lopinavir/ritonavir as single-drug therapy for maintenance of HIV-1 viral suppression: 48-week results of a randomized, controlled, open-label, proof-of-concept pilot clinical trial (OK Study).

OBJECTIVE: This study evaluated maintenance with lopinavir/ritonavir monotherapy vs. continuing lopinavir/ritonavir and 2 nucleosides in HIV-infected patients with suppressed HIV replication. DESIGN: Randomized, controlled, open-label, multicenter, pilot clinical trial. METHODS: Adult patients were eligible if they had no history of virologic failure while receiving a protease inhibitor, were receiving 2 nucleosides + lopinavir/ritonavir (400/100 mg b.i.d.) for >1 month and had maintained serum HIV RNA <50 copies/mL for >6 months prior to enrollment. RESULTS: Forty-two patients were randomly assigned 1:1 to continue or stop the nucleosides. At baseline there were no significant differences between groups in median CD4 cells/muL (baseline or nadir), pre-HAART (highly active antiretroviral therapy) HIV log10 viremia, or time with HIV RNA <50 copies/mL prior to enrollment. After 48 weeks of follow-up, percentage of patients remaining at <50 HIV RNA copies/mL (intention to treat, M = F) was 81% for the monotherapy group (95% CI: 64% to 98%) vs. 95% for the triple-therapy group (95% CI: 86% to 100%); P = 0.34. Patients in whom monotherapy failed had significantly worse adherence than patients who remained virally suppressed on monotherapy. Monotherapy failures did not show primary resistance mutations in the protease gene and were successfully reinduced with prerandomization nucleosides. Mean change in CD4 cells/microL: +70 (monotherapy) and +8 (triple) (P = 0.27). Mean serum fasting lipids remained stable in both groups. No serious adverse events were observed. CONCLUSION: Most of the patients maintained with lopinavir/ritonavir monotherapy remain with undetectable viral load after 48 weeks. Failures of lopinavir/ritonavir monotherapy were not associated with the development of primary resistance mutations in the protease gene and could be successfully reinduced adding back prior nucleosides.
