Los cambios producidos durante el estado de alarma debido a la COVID-19 en un Servicio de Urología de un Hospital Universitario Terciario en Portugal / What has changed during the state of emergency due to COVID-19 on an Academic Urology Department of a Tertiary Hospital in Portugal

OBJETIVO: Comparar la actividad del Servicio de Urología de un Hospital Universitario Portugués durante el estado de alarma y el periodo equivalente del año anterior. Comparamos el número de consultas electivas y pruebas diagnósticas urológicas, el número y el tipo de cirugías electivas, así como las características demográficas de los pacientes y las principales causas de ingreso al Servicio de Urgencias (SU) de Urología durante los dos periodos mencionados. MATERIALES Y MÉTODOS: Los datos de 691 pacientes que acudieron a urgencias desde el 18 de marzo de 2020 hasta el 2 de mayo de 2020 -y del mismo periodo del año anterior- se recogieron del software medico institucional. Los datos recopilados fueron edad, sexo, fecha de visita al servicio de urgencias, derivación desde otros hospitales, color del triaje, causa del ingreso, diagnóstico al alta y la necesidad de cirugía de urgencia u hospitalización. Con la intención de identificar las asociaciones entre las variables demográficas y clínicas con el hecho de haber sido sometido a una cirugía de urgencia (variable), se aplicaron modelos de regresión logística. RESULTADOS: El análisis multivariante mostró asociación entre el sexo del paciente con el hecho de ser sometido a una cirugía, con una disminución del 65,6% en las probabilidades para el género masculino. El periodo (COVID versus sin-COVID) no mostró una asociación significativa con la cirugía. CONCLUSIÓN: Nuestro departamento experimentó una reducción importante en la actividad. También observamos una reducción de las causas urgentes para acudir a los servicios de urgencias considerados menos graves. El porcentaje de casos que requirieron cirugía de urgencia y hospitalización fue mayor durante el periodo COVID

OBJECTIVE: To compare the activity the Urology Department of a Portuguese Academic Hospital during the state of emergency and the equivalent period at the previous year. We compared the number of elective consultations and diagnostic urologic examinations, number and type of elective surgeries, as well as patients’ demographic characteristics and main causes of presentation to Urology Emergency Department (ED) during the two mentioned periods MATERIALS AND METHODS: Data from 691 patients coming to emergency department were collected from institutional clinical software from March 18 th 2020 to May 2 nd 2020 - and from the same period the previous year. Data collected were age, sex, day of the presentation to Emergency Department, referral from other hospitals, triage color, reason of admission, diagnosis of discharge, and the need for emergency surgery or hospitalization. In order to identify associations between demographic and clinical variables with having been submitted to an emergency surgery (outcome), logistic regression models were applied. RESULTS: Multivariable analysis showed an association of sex with being submitted to surgery, 65.6% decrease in the odds for the male gender. The period (COVID versus non-COVID) did not show a significant association with surgery. CONCLUSION: Our department experienced a noticeable activity reduction. We also observe a reduction in urgent causes to attend the ED considered less serious. The percentage of cases requiring emergency surgery and hospitalization was higher during COVID-period

Fungi in the respiratory tract of horses with recurrent airway obstruction / Presença de fungos no trato respiratório de equinos e sua associação com obstrução recorrente das vias aéreas

This study aims to compare the concentration of viable fungi, especially those of the genus Aspergillus in the respiratory tract of stabled horses with and without Recurrent Airway Obstruction (RAO). Thirty two housed horses from four equestrian centers in Brazil were included in the study. These animals were submitted to clinical examination and to a respiratory sample collection. They were categorized into two groups: healthy and RAO-affected horses. Samples obtained by tracheobronchial washes were evaluated for fungal microscopy, quantitative culture and Aspergillus spp. quantification. Eighteen healthy and 14 RAO-affected horses were studied. Fungi were more frequently recovered in the RAO group, in comparison to controls, for both fungal microscopy (P<0.0001), fungal culture (P<0.0001) and Aspergillus spp. quantitative culture (p=0.001). In conclusion, horses with RAO have significantly higher fungal load in the respiratory tract in comparison to healthy horses. The implications of these findings in terms of the pathogenesis of RAO deserve additional investigation...

Este estudo objetivou comparar a concentração de fungos viáveis, especialmente do gênero Aspergillus, no trato respiratório de equinos estabulados com e sem obstrução recorrente das vias aéreas (ORVA). Trinta e dois equinos provenientes de quatro centros de treinamento equestre do Brasil foram incluídos no estudo. Os animais foram submetidos a exame clínico e coleta de amostra respiratória, sendo categorizados em dois grupos: sadios e ORVA. Os lavados traqueobrônquicos obtidos foram avaliados por exame micológico direto e cultivo quantitativo. Ao todo, 18 equinos saudáveis e 14 com ORVA foram estudados. Fungos foram mais frequentemente detectados em amostras do grupo ORVA em comparação com o grupo controle, tanto no exame micológico direto (P<0,0001) e cultivo quantitativo (P<0,0001) quanto na concentração de unidades formadoras de colônias (UFC) de Aspergillus spp. isolada em cultivo (p=0,001). Equinos com ORVA têm maior concentração de propágulos fúngicos no trato respiratório em comparação com animais sadios. As implicações desses achados na patogenia da ORVA merecem maior atenção e investigação...

Different risk factors for candidemia occur for Candida species belonging to the C. parapsilosis complex.

Previous studies have demonstrated reduced virulence in the species that comprise the Candida parapsilosis complex. We investigated a cohort of 93 patients with candidemia caused by this complex. Most infections were caused by C. parapsilosis (80.6%), followed by C. orthopsilosis (18.3%) and C. metapsilosis (1.1%). Renal failure (P < 0.001) and chronic liver diseases (P = 0.019) were more frequently encountered with infections caused by the C. orthopsilosis group, suggesting an association with patients who had a greater state of immune suppression in comparison with infections caused by C. parapsilosis sensu stricto.

Cryptococcuria as manifestation of disseminated cryptococcosis: Staib agar as a selective identification medium.

We conducted a retrospective study of 58 cases of cryptococcosis (1986-2008) with urine test positive for Cryptococcus sp, in Mycology Laboratory, Santa Casa-Hospital Complex, Porto Alegre, RS, Brazil. The diagnosis of cryptococcuria was based on microscopic examination and culture of urinary sediment. Cryptococcus was isolated from other clinical specimens such as blood, cerebrospinal fluid, ascitic and pleural fluids, respiratory secretions, biopsies of skin, nasal and bone marrow. Cryptocccus neoformans was present in 55 cases and Cryptocccus gattii in three cases. Males predominated (79.3%); age ranged from 12 to 86 years. Acquired Immune Deficiency Syndrome (AIDS) were present in 60.3%, 31.1% did not have AIDS and 5.2% were apparently immunocompetent patients. The most frequent signs and symptoms were headache (53.4%) and fever (51.7%). The most widely used medication was the amphotericin B (43 patients). The mortality rate was 45%. We conclude that the mycological examination of the urine can be an alternative simple, non-invasive and useful in diagnosis of disseminated cryptococcosis, especially when used in conjunction with techniques for demonstration of the capsule (nigrosine) and/or production of melanin in special culture media (Staib agar).

Brain death epidemiology in Uruguay and utilization of the Glasgow coma score in acute brain injured patients as a predictor of brain death.

OBJECTIVE: The knowledge of brain death (BD) epidemiology and the acute brain injury (ABI) progression profile are relevant to improve public health programs, organ procurement strategies, as well as intensive care unit (ICU) protocols aiming to increase the detection of potential donors. The aim of this study was to analyze the BD epidemiology and the ABI progression profile among subjects admitted to ICUs with a Glasgow Coma Score (GCS) < or = 8. MATERIALS AND METHODS: This was a prospective, observational study of BD reported to the National Institute of Donation and Transplantation from 2000-2006. The patients with ABI and GCS < or = 8 who were admitted to 5 ICUs with In-hospital Transplant Coordination were analyzed over the period of 2005-2007. RESULTS: The BD detection increased from 28.7 in 2000 to 58.5 BD pmp in 2006. The real donor global rate increased from 10 to 24.6 pmp from 2000 to 2006. The ABI patients with GCS < or = 8 had a global mortality rate of 56%, including 23.4% who evolved to BD. CONCLUSIONS: This study showed a 200% increment of detected BD and 150% of real donors, although these results are still below the international figures. GCS follow-up appeared to be a good tool to predict the BD outcome. The follow-up of patients with ABI allowed us to improve our BD detection strategy.

The importance of central venous catheter removal in patients with candidaemia: time to rethink our practice?

The issue of central venous catheter (CVC) removal in adult patients with candidaemia remains controversial. Although removal of CVCs has been advocated as an adjunctive strategy for treating patients with candidaemia, most studies have failed to control for important variables, e.g., the severity of illness and persistence of neutropenia. Multivariate analysis has failed to identify a significant effect of CVC removal on the prognosis for patients with candidaemia. A properly designed randomised trial that controls for confounding variables is necessary to clarify the importance of CVC removal in such patients. Until this evidence is available, systematic removal of all CVCs in these patients seems not to be justified.

Infección nosocomial por Trichosporon asahii: revisión clínica de 22 casos / Nosocomial infection due to Trichosporon asahii: clinical revision of 22 cases

Presentamos una serie de 22 casos de infección nosocomial por Trichosporon asahii, detectados en un periodo de seis años (1999-2005). Los pacientes presentaron edades entre 6 y 72 años, con un promedio de 47,3 años y con leve predominio de hombres. Las enfermedades subyacentes, fueron insuficiencia respiratoria, cáncer, diabetes, insuficiencia renal crónica, cirrosis y sida. Las condiciones predisponentes fueron antibioterapia,ventilación mecánica, sonda vesical, catéter, corticoides, trasplantes, inmunosupresores, quimioterapia, granulocitopenia, procedimiento quirúrgico y diálisis peritoneal ambulatoria continua. Los antifúngicos más utilizados fueron el fluconazol y la anfotericina B. Algunos pacientes recibieron varios antifúngicos. Cinco pacientes no fueron tratados con antifúngicos y un paciente recibió factor de estimulación de colonias granulocíticas (G-CSF). De los 22 pacientes, nueve presentaron mejoría clínica, otros nueve pacientes fallecieron y de cuatro pacientes de desconoce su evolución(AU)

Twenty two cases of nosocomial infection caused by Trichosporon asahii, detected during a period of six years (1999-2005) is described. The patients were predominantly males with an average age of 47.3 years-old. The predominant diseases in the study group were respiratory insufficiency, cancer, diabetes, chronic renal insufficiency, cirrhosis and AIDS. The main predisposing conditions were antibiotic therapy, mechanical ventilation, urethral catheterization, catheter, corticoids, transplant, immunosuppressive therapy, chemotherapy, granulocytopenia, surgical procedures and continuous ambulatory peritoneal dialysis. The most used antifungal drugs were fluconazole and amphotericin B. In some cases several antifungals were administered. Five patients did not receive antifungal treatment, and one patient received granulocyte colony stimulating factor (G-CSF). Nine patients showed clinical improvement, nine died and the progress of four patients is unknown. T. asahii is an emergent pathogen in patients with immunodeficiency and its presence in these type hosts can not be considered colonization, as there is an important risk of invasive infection. So, in susceptible patients to develop trichosporonosis it is advisable to take into consideration this disease especially in intensive clinical care units(AU)

Risk factors and outcome for nosocomial breakthrough candidaemia.

OBJECTIVES: To describe all cases of nosocomial candidaemia that occurred in patients in use of anti-fungals. METHODS: Retrospective cohort study (1995-2003). Breakthrough candidaemia was defined as the occurrence of candidaemia in a patient receiving at least 3 days of systemic anti-fungal therapy. Patients with breakthrough candidaemia were compared to patients with non-breakthrough candidaemia. RESULTS: During the period of study, 20 patients had breakthrough candidaemia, and 40% of them had cancer. While most of these episodes occurred with amphotericin B, some patients received low-dose regimens of fluconazole or ketoconazole in association with ranitidine. Non-Candida albicans species caused 75% of these infections, mainly Candida parapsilosis (30%). When compared to controls (n=171), the breakthrough group had more frequently mucositis, longer stay in the intensive care unit, and longer periods of hyperalimentation, mechanical ventilation, urinary catheter and broad-spectrum antibiotics. Candida isolation from sites other than blood occurred more frequently in the breakthrough group. Mortality rate and Candida species distribution were similar among groups. CONCLUSIONS: C. parapsilosis was the main aetiology of breakthrough candidaemia. Common risk factors included mucositis, isolation of Candida from sites other than blood, use of broad-spectrum antibiotics, and invasive medical procedures. No difference in the mortality rate was observed.

A 9-year study comparing risk factors and the outcome of paediatric and adults with nosocomial candidaemia.

Although there are numerous studies of candidaemia in adults, data on paediatrics are still limited. The aim of this study was to compare risk factors, aetiology, therapy, and the outcome of nosocomial candidaemia among paediatric and adult patients in a large Brazilian tertiary hospital (1995-2003). During this period, 78 paediatrics and 113 adults were studied. Species other than Candida albicans caused 78.2% of episodes of candidaemia in paediatrics. Compared to adults, paediatrics received more frequently broad-spectrum antibiotics, vasopressors, blood transfusions, arterial catheter, chest tube, cardiothoracic surgery, mechanical ventilation, and parenteral nutrition. Candidaemia caused by Candida parapsilosis was more common in paediatrics, as was the isolation of Candida spp. from catheters. Amphotericin B treatment was more common in paediatrics. Mortality rate was higher in adults than in paediatrics with nosocomial candidaemia. We reinforce the necessity of continuous epidemiologic surveillance to follow the dynamics of candidaemia.

A comparative study of risk factors and outcome among outpatient-acquired and nosocomial candidaemia.

Candidaemia is perceived as a nosocomial infection. The aim of this study was to describe all cases of candidaemia that occurred in the outpatient setting, and to compare risk factors and outcome among patients with outpatient-acquired and nosocomial candidaemia. During 1995 and 2003, 210 patients developed candidaemia at our institution, and 9.0% were outpatient acquired. Major underlying diseases were cancer (47.4%) and chronic renal failure (36.8%). Most occurred within 24 h of hospitalization (63.2%), and 83.7% were caused by species other than Candida albicans, mainly Candida parapsilosis (36.8%). Candida spp. were isolated from catheters in 21% of cases, and 52.6% of patients had been admitted to hospital in the 60 days preceding candidaemia. Compared with patients with nosocomial candidaemia, chronic renal failure was more frequent in the outpatient group, who were also more commonly exposed to haemodialysis. Ileus, gastrointestinal bleeding, previous bacteraemia, use of proton pump inhibitors, previous stay in the intensive care unit and requirement for antibiotics, blood transfusion, vasopressors and invasive medical procedures were more frequent in the nosocomial group. Overall mortality was high in both groups. Candidaemia must be considered as a potential cause of sepsis in the community, and it is associated with a high mortality rate.

Chronic pulmonary paracoccidioidomycosis in the state of Rio Grande do Sul, Brazil.

Since 1942, when paracoccidioidomycosis was first identified in the state of Rio Grande do Sul, paracoccidioidal pulmonary lesions became a great concern to physicians. The present study focuses on 53 patients diagnosed over a seven-year period who presented paracoccidioidal lesions circumscribed to the lungs. These patients presented clinical and radiological features that simulated several pulmonary infectious and non-infectious conditions. Four unusual cases are briefly discussed. A sequence of laboratorial tests should be established for the diagnosis of pulmonary paracoccidioidomycosis.

Peritonitis by scedosporium apiospermum in a patient undergoing continuous ambulatory peritoneal dialysis.

A case of peritonitis due to Scedosporium apiospermum in a boy undergoing continuous ambulatory peritoneal dialysis is reported. The finding of suggestive tissual form of the fungus in the effluent hastened the diagnosis of the infection.
