Multirresistencia, resistencia extendida y panresistencia a antibacterianos en el norte de México.

OBJETIVO: Describir el perfil de multirresistencia (MDR), resistencia extendida (XDR) y panresistencia (PDR) a antibacterianos en aislados de muestras de pacientes de un hospital privado de tercer nivel en el norte de México. MÉTODO: Se realizó un estudio retrospectivo durante el periodo comprendido de febrero de 2016 a abril de 2019. A partir de 156 muestras clínicas de orina, heridas, sangre, expectoración y otros fluidos se aislaron 166 bacterias; 10 de las muestras incluyeron dos microorganismos. Los microrganismos aislados se clasificaron en MDR, XDR o PDR. RESULTADOS: El 78% de los aislados gramnegativos y el 69% de los aislados grampositivos mostraron MDR, XDR o PDR. Staphylococcus epidermidis fue la bacteria grampositiva con multirresistencia más frecuentemente aislada. Escherichia coli y Klebsiella sp. se encontraron entre los gramnegativos MDR más frecuentes. En dos casos, los aislados clínicos de Pseudomonas aeruginosa procedentes de la unidad de cuidados intensivos neonatales mostraron PDR. CONCLUSIÓN: Los servicios de terapia intensiva, cirugía y unidad de cuidados intensivos neonatales merecen especial atención por la alta proporción de aislados MDR y la presencia de PDR a causa de P. aeruginosa. OBJECTIVE: To describe the profile of multidrug-resistance (MDR), extensively resistance (XDR) and pandrug-resistance (PDR) to antibacterial drugs in isolates from patient samples from a third level private hospital in the North of Mexico. METHOD: A retrospective study was carried out during the period from February 2016 to April 2019. From 156 clinical samples of urine, wounds, blood, expectoration and other fluids, 166 bacteria were isolated; 10 samples included two microorganisms. Isolated microorganisms were classified into MDR, XDR or PDR. RESULTS: 78% of the Gram negative and 69% of the Gram positive isolates showed MDR, XDR or PDR. Staphylococcus epidermidis was the most frequently isolated MDR Gram positive bacteria. Escherichia coli and Klebsiella sp. were among the most frequent MDR Gram negative. In two cases, the clinical isolates of Pseudomonas aeruginosa from the neonatal intensive care unit showed PDR. CONCLUSIONS: The intensive care, surgery and neonatal intensive care unit services deserve special attention due to the high proportion of MDR isolates and the presence of PDR due to P. aeruginosa.

Zika Virus in Salivary Glands of Five Different Species of Wild-Caught Mosquitoes from Mexico.

Zika virus (ZIKV) is a mosquito-borne pathogen, and Aedes aegypti has been identified as the main vector of the disease. Other mosquito species in the Aedes and Culex genera have been suggested to have the potential for being competent vectors based on experimental exposition of mosquitoes to an infectious blood meal containing ZIKV. Here, we report the isolation in cell culture of ZIKV obtained from different body parts of wild-caught female mosquitoes (Ae. aegypti, Ae. vexans, Cx. quinquefasciatus, Cx. coronator, and Cx. tarsalis) and whole male mosquitoes (Ae. aegypti and Cx. quinquefasciatus) in Mexico. Importantly, this is the first report that shows the presence of the virus in the salivary glands of the wild-caught female mosquitoes species, Cx. coronator, Cx. tarsalis, and Ae. vexans. Our findings strongly suggest that all the species reported herein are potential vectors for ZIKV.

[Complaints for treatment of uterine myomatosis]. / Inconformidades por tratamiento de miomatosis uterina.

Complaints related to uterine myomatosis treatments received by the National Commission of Medical Arbitration (Conamed) between 2001 and 2005 were analyzed. Complaints were from patients affiliated to social security institutions (51.7 %), private providers (34.5 %) and public health care services (13.8 %). A medical doctor suggested to fill in the complaint in 10.3 % of cases. Perception of inadequate treatment was the most frequent cause (69 %), incomplete medical charts were 60.3 % and only 24 % included the informed consent form. Medical information given to patients and relatives was inadequate (48.2 %). Hysterectomy was performed to 84.5 % of patients. The most frequent surgical complications were hemorrhage (25.7 %), urologic injuries (25.7 %) and surgical infections (12.7 %). 36.4 % of cases had no surgical complication. Main sequelae were: elapsed length of hospital stay (15 %) and loss of an organ (other than uterus) or function (not reproductive) (13.8 %). There was one death (1.7 %). Medical malpractice was found in 29.3 % of cases. Principal deviations: communication problems (29.6 %), unjustified delayed surgery (29.4 %) and delayed diagnosis of complications due to poor post-surgical care or premature hospital discharge (29.4 %).

[Medical attitude regarding the negative of receiving blood transfusions by Jehovah's Witness patients]. / Actitud médica ante la negativa de recibir hemotransfusión por pacientes Testigos de Jehová.

BACKGROUND: Hemoderivative and blood transfusions without proper medical indication bring uncertain benefits, increase health risks and adverse effects. It is necessary to also consider the patient's values and preferences and the denial to receive transfusions. A deficient medical evaluation and an unnecessary transfusion can generate untoward effects regarding patients' health and safety. MATERIAL AND METHODS: A retrospective, observational, and transverse study of 767 complaints for alleged denial of medical attention presented by Jehovah's Witness patients was undertaken, coupled with their denial to receive blood transfusions and their perception of the problem. RESULTS: It was established that 95.6% of cases studied involved adult patients, while 4.4% involved underage patients, with a mean of 43 years. The majority of complaints appeared at the secondary level of medical attention, 64.5% came from social security institutions and 19% from private institutions. The motive for medical consultation was surgical in 91.9% cases. 98.7% of the complaints were due to a perceived denial of medical attention, associated to religious conviction. 1.3% of complaints were filed after having received blood transfusions, without proper patient consent. The major health problems were solved in different medical units from the beginning in 500 cases (65.2%). Medical care was provided in 450 cases, in private clinics, while 50 cases were cared for in public institutions without the need for transfusion. CONCLUSIONS: Several studies coincide on the high number of unnecessary or unjustified blood transfusions. To improve the quality of transfusion medicine steps should be taken to install specialized hospital committees, update the use of guidelines based on the best scientific evidence, as well as to respect patient autonomy.

[Clinical guides in Mexico, emission of the Academia Mexicana de Cirugia]. / Guías clínicas en México, emisión de la Academia Mexicana de Cirugía.

Today, these exist worldwide organizations related with the practice of medicine that are interested in marking recommendations and in formulating guidelines for better performance of physicians and health professionals. These organizations are headed by universities, associations, colleges, research center, and work groups and are made up of well-known physicians with academic prestige from the private and public sectors. This report presents a brief overview concerning the development of three clinical guides related with illnesses frequently observed in the physician's office: rhinosinusitis gastroesophageal reflux diseases (GERD), and prostate benign hyperplasia. These guides are issued by one of the most important academic institutions in the country. In the above-mentioned works, the efforts of specialist who are opinion leaders in these topics form different states of the country converge. Likewise, critical points to consider for producing clinical guides are provided mechanisms of diffusion, consultation, feedback and updating of these documents, have already been provided and focus on national medical practice quality of services, and the manner in which to carry out diagnosis and therapy at the different levels of medical care, with emphasis on preventing complications.
