[Septic shock originating from a pulmonary focus caused by Pasteurella multocida. Report of one case]. / Shock séptico de foco respiratorio por Pasteurella multocida en un paciente inmunocompetente. Caso Clínico.

Pasteurella multocida is a gram-negative coccobacillus bacterium found as a commensal in the oropharynx of domestic animals such as cats and dogs and some farm animals. Soft tissue infections and occasionally bacteremia in immunocompromised patients with direct contact with animals are described. We report a 61 year old male with a history of scratches and close contact with domestic cats, with a septic shock originating from a pulmonary focus, requiring mechanical ventilation and vasopressors. Blood cultures disclosed the presence of Pasteurella multocida. He responded successfully to antimicrobials.

Immunohistochemical Expression of Ki-67, Dopamine D1 and Dopamine D2 Receptors in Meningiomas in a Tertiary Institution in Mexico.

Objectives Meningiomas (MNGs) are the most common intracranial tumors found in the adult population. While most intracranial MNGs may be surgically removed, a subset of patients remains ineligible for conventional treatment. This is either because of a lack of surgical access or due to atypical, anaplastic or invasive characteristics of the tumors. These patients may benefit from targeted therapies that focus on cell receptor expression. The aim of this study was to assess dopamine receptor (DR) and Ki-67 expression in the MGNs of patients treated with surgery in the Instituto Nacional de Neurología y Neurocirugía, Mexico. Materials and methods This study analyzed 23 patients with confirmed MNG diagnoses (10 female and 13 male (mean age: 44.5 years)) who had undergone surgical resection between 2010 and 2014 at our institution. In the collected samples, we performed analyses for Ki-67, Dopamine 1 and Dopamine 2 receptors' expression. Results For the markers Ki-67, DR-D1 and DR-D2, the mean percentual expressions were 18.9%, 23.02% and 8.33%. No significant correlation was found between the expressions of these receptors and the studied MNG characteristics. The expression index of Ki-67 showed a significant relation with mean age (p = 0.03) and prolactin levels (p = 0.02). Conclusions Samples showed varied expressions of the studied receptors. Despite the difference in expressions between the markers, more studies are needed to confirm the findings. In contrast to previous studies, we could not find any relationship between D2-R and tumor characteristics.

Clinical and anatomic description of patients with arteriovenous malformation treated with endovascular therapy in a Mexican population.

OBJECTIVE: Arteriovenous malformations (AVMs) are benign congenital lesions. The estimated prevalence is 10-18 per 100,000 individuals, with an incidence rate of 1.1-1.4 per 100,000 person-year; only 12% of AVMs present symptoms during life. It is important to study different characteristics associated with AVMs because these patients require multidisciplinary treatment. METHODS: A descriptive, observational, longitudinal, and retrospective study was carried out from January 15, 2016 to October 19, 2021. Convenience sampling was used on patients diagnosed with arteriovenous malformation. Sociodemographic data was obtained, such as: sex, age, site, predominant symptoms, clinical debut, type of malformation, data associated with post therapy evolution, type of embolizing agent used, associated complications, Rankin scale, and death. RESULTS: Data from 535 procedures was collected, we calculated an incidence of 4.4 cases per million inhabitants. Ninety procedures in 56 patients that used endovascular therapy were obtained with a female-male ratio of 0.75 and an age distribution of 35±14 (SD). A 36.3±11.5 (SD) mm diameter was registered. There was a 33% success rate for endovascular surgery. CONCLUSIONS: The multidisciplinary treatment of AVMs is made up of three pillar techniques: microsurgical resection, embolization, and radio-neurosurgery. It is extremely important to make an appropriate decision, with an emphasis on achieving better functional outcomes for the patient. Although neurological endovascular therapy was initially used as an adjuvant treatment for neurosurgery and radio-neurosurgery, it has been used more and more frequently as the first line of treatment.

Sistema hospitalario en situación de crisis: implementación de sistema de comando de incidentes para enfrentar pandemia SARS-CoV-2 en Clínica Las Condes, Chile / Implementation of incident command system to deal with SARS-CoV-2 pandemic in Clínica Las Condes, Chile

La pandemia en Chile generó un desafío de modernización y gestión de los Cuidados Intensivos, haciendo necesario que las unidades de pacientes críticos realizaran un aumento de su capacidad hospitalaria, lo que requiere preparar una infraestructura, un equipamiento mínimo, protocolos y un equipo humano preparado y alineado, para garantizar la seguridad y calidad de atención a los pacientes. Una forma de lograrlo es la incorporación de la estrategia militar de Sistema de Comando de Incidentes, utilizado para enfrentar distintos tipos de desastres, con una estructura modular de comando y sus seccionales de trabajo, con diferentes equipos y líderes para hacer frentes a los variados desafíos. El objetivo de este artículo es describir la instauración del sistema de comando de incidentes en un hospital privado, detallando su conformación y los resultados logrados.

The pandemic in Chile has been a real challenge in terms of modernization and management of intensive care. Critical care units have been forced to increase their hospital capacity in terms of infrastructure, equipment, protocols and human team, while guaranteeing safety and high-quality patient care.One approach to achieve this objective is to develop the army strategy called incident command system that has been used to face different types of disaster. A modular command structure is developed based on the creation of teams each lead by an expert in different areas in order to cope with a variety of upcoming challenges.The objective of this article is to describe the setting up of a successful incident command system in a private hospital, detailing its formation and results obtained.

Use of whey as a culture medium for Bacillus clausii for the production of protein hydrolysates with antimicrobial and antioxidant activity.

The use of whey as a natural culture medium to produce hydrolysates with antimicrobial from Bacillus clausii is the objective of this research. The fermentation process was carried out at 25 ℃ for five days, where proteolytic activity, soluble peptides quantification, and antimicrobial activity using the disc diffusion method were determined every day. The fermented whey reached values ​​of proteolytic activity between 90 and 260 U ml-1 and a production of soluble peptides between 100 and 2070 µg ml-1. The maximum values ​​were reached after three days of fermentation to all determinations. In addition, the inhibition zone of fermented whey against Salmonella Typhimurium, Escherichia coli, Shigella flexneri, Staphylococcus aureus, Listeria monocytogenes, and Enterococcus faecalis strains were 13.7, 13.2, 14.4, 14.6, 9.8, 15.7 mm, respectively. The hydrolysates inhibited the 2, 2'-azinobis (3-ethylbenzothiazoline- 6-sulfonic acid) (ABTS) and 2, 2-diphenyl-1-picrylhydrazyl (DPPH) radicals by 85 and 80%, respectively. The whey was used to allow the growth of B. clausii and to generate peptides with antioxidant and antimicrobial activity through the hydrolysis of proteins present in the natural culture medium. This process could be used for the development of new dairy products added with probiotics.

Prevention of Crush Syndrome through Aggressive Early Resuscitation: Clinical Case in a Buried Worker.

UNLABELLED: Introduction Crush syndrome, of which little is known, occurs as a result of compression injury to the muscles. This syndrome is characterized by systemic manifestations such as acute kidney injury (AKI), hypovolemic shock, and hydroelectrolytic variations. This pathology presents high morbidity and mortality if not managed aggressively by prehospital care. Clinical Case A 40-year-old worker was rescued after being buried underground in a ditch for 19 hours. The patient was administered early resuscitation with isotonic solutions and monitored during the entire rescue operation. Despite having increased plasma levels of total creatine kinase (CK), the patient did not develop AKI or hydroelectrolytic variations. CONCLUSION: Aggressive early management with isotonic solutions before hospital arrival is an effective option for nephron-protection and prevention of crush syndrome.
