Prevención de la infección neonatal precoz por estreptococo del grupo B

El estreptococo del grupo B (EGB) constituye la principal causa de morbimortalidad neonatal y de morbilidad materna durante el embarazo y el posparto. Coloniza el aparato digestivo y el genitourinario en un 10-30% de las gestantes, con una tasa de transmisión vertical del 50%. De entre los recién nacidos colonizados, un 1-2% desarrollará una sepsis grave precoz. Se ha realizado una revisión bibliográfica con el objetivo de conocer las estrategias de prevención de la infección neonatal por EGB. Los resultados ponen de manifiesto que las recomendaciones para su prevención consisten en el cribado universal prenatal de colonización por EGB mediante cultivo vaginorrectal a las 35-37 semanas, y la administración de profilaxis antibiótica intraparto a todas las embarazadas portadoras.

Percutaneous access versus standard femoral exposure for endovascular abdominal aortic aneurysm repair: a randomized, controlled trial

The treatment of abdominal aortic aneurysm (AAA) has shifted from the exposure of the aorta artery in an open repair technique to a small groin cut in an endovascular repair. Recently, a percutaneous access for endovascular repair has appeared. This new technique aims to minimize the complications of the common femoral artery exposure, the patient discomfort and the length of hospitalizationObjectives: To compare the proportion of discharged patients within the first 48 postoperative hours of two common femoral artery accesses for endovascular repair of AAA: the open exposure technique and the percutaneous technique. Secondary objectives include to evaluate the total procedure time, the femoral access complications, the need for extra analgesia and the patient satisfaction and groin discomfort of the two techniquesDesign: Randomized controlled trial conducted between 2014 and 2017Participants: Patients diagnosed with abdominal aortic aneurysm with elective endovascular repair indication

Five years of sleep apnea treatment with a mandibular advancement device. Side effects and technical complications

Objective: To determine the variation in prevalence of temporomandibular disorders (TMD), other side effects, and technical complications during 5 years of sleep apnea treatment with a mandibular advancement device. Materials and Methods: Forty patients diagnosed with obstructive sleep apnea received an adjustable appliance at 70% of the maximum protrusion. The protrusion was then progressively increased. TMD (diagnosed according to the Research Diagnostic Criteria for TMD), overjet, overbite, occlusal contacts, subjective side effects, and technical complications were recorded before and a mean of 14, 21, and 58 months after treatment and analyzed by the Wilcoxon test (P Less-than .05). Results: Fifteen patients still used the oral appliance at the 5-year follow-up, and no significant variation in TMD prevalence was observed. Subjective side effects were common, and a significant reduction was found in overjet, overbite, and in the number of occlusal contacts. Furthermore, the patients made a mean of 2.5 unscheduled dental visits per year and a mean of 0.8 appliance repairs/relines per year by a dental technician. The most frequent unscheduled visits were needed during the first year and were a result of acrylic breakage on the lateral telescopic attachment, poor retention, and other adjustments to improve comfort. Conclusions: Five-year oral appliance treatment does not affect TMD prevalence but is associated with permanent occlusal changes in most sleep apnea patients during the first 2 years. Patients seek several unscheduled visits, mainly because of technical complications.

Complications following an accidental sodium hypochlorite extrusion: A report of two cases

Sodium hypochlorite (NaOCl) is the most commonly used solution in root canal treatments, as it is a low-cost method that displays a very effective antimicrobial activity against microbiota of infected root canals. However, this solution can cause complications especially due to its cytotoxic features. When this solution is injected into the adjacent tissues, the patient usually experiences intense pain, and an urgent treatment should be implemented in order to prevent a long-term sequelae. This paper describes the clinical features of two patients that experienced an accidental extrusion of NaOCl after endodontic treatment of varying severity and with different treatments. Furthermore, it shows the long-term neurologic injuries that this type of accidents may cause and a treatment protocol for these situations will be suggested.
