Recurrent urinary tract infections: Evaluation of the prophylactic efficacy of urinary antiseptics methenamine and methylthioninium chloride

Introduction: Urinary tract infection (UTI) is a very common condition in clinical practice, affecting an estimated 50% of all adult women during a lifetime. The most common causative agent is E. coli; UTI may also be caused by S. saprophyticus, Enterobacteria (Klebsiella sp and Serratia sp.), Enterococcus sp., and P aeruginosa. Recurrent UTIs occur at least twice per semester or three times a year. Prophylactic measures to prevent recurrent UTIs include changes in contraception methods, cranberry products, increased fluid intake, urination after intercourse, vaginal estrogen therapy for post-menopausal women, antibiotics, and urinary tract antiseptic agents. Objectives: To evaluate the use of a combination of methenamine and methyl-thioninium chloride in the prophylaxis of recurrent uncomplicated lower UTIs, with respect to: • Signs and symptoms of UTI • Etiologic agent(s) • Recurrence rates • Need for antibiotic therapy in case of recurrence • Incidence of adverse events associated with the treatment, including any reported alterations of laboratory tests Materials & methods: A descriptive, analytic, restrospective study was performed at Hospital Universitário Constantino Otaviano - UNIFESO. Medical charts from patients presenting recurrent uncomplicated lower UTI attended from 2001-present were analyzed, including the following information: Demographic data (age, gender, weight, ethnicity, living conditions): medical history/signs and symptoms of UTI; identification of treatment and dosing regimens; treatment duration; recurrence rates and need for antibiotic therapy in case of recurrence; other medications prescribed; and records of adverse events. Results: E. coli was identified as etiologic agent in 80% of the patients. Following antibiotic therapy, all patients received prophylactic treatment with the combination of methenamine and methylthioninium chloride. Treatment duration ranged from three to six months. Adverse events were observed in 13/60 patients (21.7%). At the end of the respective treatment periods, a statistically significant (p<0.0001) number of patients showed no UTI recurrence. Conclusion: Based on the results from the collected data, we conclude that an orally administered combination of methenamine and methylthioninium chloride is safe and effective in the prophylactic treatment of recurrent uncomplicated lower urinary tract infection. © Copyright Morelra Jr. Editora.

Ki-67 and CD100 immunohistochemical expression is associated with local recurrence and poor prognosis in soft tissue sarcomas, respectively

Soft tissue sarcomas (STSs) are a heterogeneous group of mesenchymal tumors of >50 subtypes. However, STSs represent <1% of types of cancer. Despite this low frequency, the disease is aggressive and treatment, when possible, is based on traditional chemotherapies. A number of cases of resistance to adjuvant therapies have been reported. Metastases are commonly identified in STS patients during diagnosis and the development of effective clinical parameters is crucial for correct management of the disease. The use of biological markers in cancer is a useful tool to determine patient prognosis. Ki--67 is a protein marker for proliferation of somatic cells and is widely used in prognostic studies of various types of tumor, including STSs. Cluster of differentiation 100 (CD100) is a member of the semaphorin family. The family was initially described as axon guidance molecules important for angiogenesis, organogenesis, apoptosis and neoplasia. CD100 was previously utilized as a prognostic factor in tumors and also in STSs. In the present study, protein expression of Ki--67 and CD100 was analyzed by immunohistochemistry in samples of STS patients of the Barretos Cancer Hospital (Barretos, Brazil) to establish prognostic criteria of the disease. Results demonstrate a correlation between CD100 expression and poor prognosis, consistent with a previous study. Moreover, the expression of Ki-67 was identified to correlate with presence of local or locoregional recurrence. To the best of our knowledge, no large casuistic study has revealed this correlation between Ki--67 and local recurrence in STSs. The use of Ki--67 and CD100 as markers in clinical pathological analysis may be suitable as a prognostic criterion in disease progression.

Inclusión de la variable etnia en las fuentes de información sociodemográfica del Ecuador

Las crecientes demandas de participación en la vida social, política y económica de los pueblos y nacionalidades indígenas del Ecuador durante los últimos veinte años han incidido directamente en la visibilización de estos actores como parte constitutiva del país. Existen varias cifras sobre el número de habitantes indígenas en el Ecuador, lo que ha impulsado un debate sobre la validez de las diferentes metodologías de recolección de información que permita tener datos desagregados por condición étnica, y lo que es más importante sobre las condiciones de vida de los pueblos y nacionalidades indígenas y las brechas de equidad que se observan en cuanto a indicadores de desarrollo entre los distintos grupos de población. El presente documento es una síntesis de la revisión de los instrumentos de recolección de información que incluyen la variable “etnia” y las diferentes formas de capturar el dato. Revisión que involucró el análisis crítico de cada uno de los procesos por parte de los responsables técnicos de la producción de las estadísticas y también con los representantes de las nacionalidades y pueblos indígenas del Ecuador con la finalidad de identificar las limitaciones de los instrumentos y/o las dificultades del proceso que hace que los pueblos indígenas se sientan sub representados en las estadísticas oficiales.
