El manejo de la vía aérea en el paciente crítico se realiza con frecuencia bajo una situación de urgencia. La probabilidad de que se presenten complicaciones y dificultades no previstas es mayor en la UCI que en el quirófano. El abordaje de la vía aérea en este entorno ha ganado interés en los últimos años, especialmente tras el cuarto trabajo de auditoría NAP4 del que se obtuvieron varias conclusiones importantes1. La primera y más interesante fue la escasa valoración de la vía aérea que se realiza en las unidades de críticos y que no permite anticiparnos a una vía aérea difícil, derivando en una planificación pobre. En segundo lugar se determinó que, en el contexto de una vía aérea difícil inesperada, la escasa capacidad de modificar el plan establecido puede derivar en un fallo en la resolución de la situación.

Resumen: La queratodermia acuagénica (QA) es una afectación dermatológica adquirida poco frecuente que se caracteriza por la aparición de edema y pápulas blanquecinas-translúcidas desencadenado por la inmersión o contacto con el agua. Se han descrito casos asociados a fármacos, hiperhidrosis y a fibrosis quística. Los objetivos del estudio son evaluar la efectividad de los distintos tratamientos existentes para la QA. Realizamos una revisión de la literatura existente al respecto hasta el momento, incluyendo series de casos y reportes de caso. El tratamiento de la QA es efectivo en las formas asociadas a hiperhidrosis. La iontoforesis del agua del grifo, la simpatectomía torácica endoscópica, las inyecciones de toxina botulínica y la oxibutinina son efectivas en las formas refractarias. La aplicación tópica de ácido salicílico o sales de aluminio es efectiva, pero resulta poco eficaz como tratamiento de mantenimiento. Probablemente la mejor alternativa para el tratamiento de la QA sea la oxibutinina 5 mg/día vo. Se ha observado que los efectos fisiopatológicos de los antiinflamatorios no esteroideos en la QA podrían justificar el uso de las prostaglandinas como un tratamiento dirigido de la enfermedad. Se necesitan estudios adicionales para fortalecer estas deducciones y abordar las incertidumbres restantes. Abstract: Aquagenic keratoderma is an uncommon acquired dermatosis characterized by edema and whitish-translucent papules triggered by immersion or contact with water. Cases have been described in association with certain medications, hyperhidrosis, and cystic fibrosis. The aim of this review is to evaluate the effectiveness of different treatments for aquagenic keratoderma. We reviewed the literature and analyzed treatments for aquagenic keratoderma described in case series and reports. Aquagenic keratoderma associated with hyperhidrosis can be treated effectively. Tap water iontophoresis, endoscopic thoracic sympathectomy, botulinum toxin injections, and oxybutynin are effective against refractory forms. Topical salicylic acid and aluminum salts are effective, but of little value as maintenance therapy. Oral oxybutynin 5 mg/d is probably the best option for treating aquagenic keratoderma. The reported pathophysiological effects of nonsteroidal anti inflammatory drugs in this setting suggest that the use of prostaglandins might be justified. Additional studies are needed to investigate these hypotheses and resolve other questions.

La patología del hormigón armado y su reparación, no cabe duda que es un tema de actualidad a nivel mundial. En este informe se expone la problemática planteada en el hormigón armado de una presa de contrafuertes, en los Pirineos de Lérida, que ocasionaba una pérdida de agua de 60 I/segundo, la solución técnica dada y su proceso de ejecución a temperaturas del orden de O °C. Una parte de la reparación fue llevada a cabo en la primavera de 1984 y, el resto, a principios de 1985. Los años transcurridos están confirmando la eficacia del tratamiento.

Objective: To define the types of overactive bladder (OAB) patient enuresis and study daytime bladder treatment response., Materials and Methods: A prospective, multi-center study of OAB patients with enuresis treated with anticholinergics or neuromodulation over 3 months from 2019 to 2021 was carried out. Variables achieved from the voiding calendar and PLUTSS (Pediatric Lower Urinary Tract Score System), as well as enuresis-related variables, were collected. Two study groups were created -primary enuresis (PE) and secondary enuresis (SE). Partial enuretic response (PER) was defined as a >  50% reduction in baseline enuresis, and complete enuretic response (CER) as a 100% reduction. A multivariate analysis was eventually conducted to detect CER independent predictive factors., Results: 152 OAB patients were included. 109 of them (71.7%) had enuresis -29 (26.7%) SE and 80 (73.3%) PE. PLUTSS score was higher in PE patients than in SE patients (20.8 vs. 17.2; p= 0.001). PER and CER were significantly higher in the SE group (55.2% vs. 15%; p= 0.000 in PER, and 48.3% vs. 5%; p= 0.000 in CER). In the multivariate analysis, SE patients demonstrated to have a 50-fold increased probability of responding to daytime bladder treatment than PE patients (OR: 49.79; 95%CI: 6.73-36.8)., Conclusions: Most OAB children have PE and not SE, which explains why enuresis does not typically respond to daytime bladder treatment. Characterizing the type of enuresis in OAB children is important to adequately approach treatment.

Objective: To determine whether sacral transcutaneous electrical nerve stimulation (S-TENS) is an effective treatment in patients refractory to anticholinergic drugs (Achs)., Materials and Methods: A prospective multi-center study of patients with overactive bladder (OB) refractory to Achs treated with S-TENS from 2018 to 2021 was carried out. S-TENS was applied over 3 months. Symptom progression was assessed using the voiding calendar and the Pediatric Lower Urinary Tract Symptoms Score (PLUTSS), excluding questions 3 and 4 -referring to enuresis- so that progression of daytime symptoms only (LUTS variable) was analyzed., Results: 66 patients -50% of whom were female- were included, with a mean age of 9.5 years (range: 5-15). S-TENS significantly lowered PLUTSS (19.1 baseline vs. 9.5 final, p< 0.001) and LUTS (13.1 baseline vs. 4.8 final, p< 0.001). It also reduced the number of mictions (8.5 baseline vs. 6.4 final, p< 0.001), while increasing urine volume in the voiding records (214 ml baseline vs. 258 ml final, p< 0.001). Enuresis was the only variable refractory to S-TENS. Complication rate was 3% (2 patients with dermatitis in the S-TENS application area)., Conclusions: S-TENS is effective and safe in the short-term in patients with OB refractory to Achs. Further studies assessing long-term efficacy and potential relapses are required.

The aim of this study was to assess a technique for serum ferritin determination by means of chemoluminiscence (Magic Lite, Ciba Corning) in a series of unselected patients. A group of 100 healthy blood donors (50 men and 50 women), in whom iron deficiency had been previously excluded, was used as control. The results were validate according to the Societé Francaise de Biologie Clinique guidances. The characteristics of the method and its comparison with IRMA and ELISA techniques are described here. Its major advantages are related with simplicity and sensitivity; the main disadvantage is the necessity to repeat every step in samples with ferritin levels over 1,500 ng/dl.
