RESUMO

Objetivo: Comparar las lesiones ureterales intraoperatorias ocasionadas durante la CRIR con inserción de VAU con la tasa de infecciones postoperatorias tras la CRIR sin inserción de VAU.Pacientes y métodosEn este ensayo aleatorizado los pacientes que recibieron una indicación de una CRIR entre enero de 2017 y diciembre de 2017 se dividieron en 2 grupos. En el grupo A no se utilizó VAU y en el grupo B sí se utilizó VAU. Se realizó la clasificación de la escala Post-Ureteroscopic Lesion Scale (PULS) tras retirar la VAU o el ureteroscopio flexible. Las lesiones del uréter proximal, medio y distal se evaluaron y compararon según la escala PULS. Además, los pacientes de ambos grupos recibieron seguimiento postoperatorio para evaluar el desarrollo de cualquier enfermedad infecciosa.ResultadosEl estudio incluyó a 181 pacientes, 89 del grupo A y 92 del grupo B. La tasa de ausencia de cálculos global, los fragmentos residuales clínicamente insignificantes y la tasa de ausencia de cálculos final fueron del 41,4%, 53,5% y 95%, respectivamente. Hubo 33 (37,1%) pacientes con lesiones ureterales en el grupo A y 42 (45,6%) pacientes con lesiones ureterales en el grupo B, sin diferencias estadísticamente significativas. Por otra parte, la tasa de infección postoperatoria fue mucho mayor en el grupo A (37,1% frente a 16,3% p=0,03).ConclusionesNo se ha visto un mayor número de lesiones ureterales tras la inserción de la VAU. La inserción de una VAU durante la CRIR resulta en una tasa menor de infecciones postoperatorias. (AU)


Objective: To compare intraoperative ureteral injuries in RIRS with UAS insertion with the rate of postoperative infections after RIRS without UAS insertion.Patients and methodsIn this randomized trial, patients who received an indication for RIRS between January 2017 and December 2017 were divided into two groups. Group A had no UAS insertion and Group B had UAS insertion. Post-Ureteroscopic Lesion Scale (PULS) grading was performed after UAS or flexible ureteroscope removal. Proximal, middle and distal ureteral lesions were evaluated and compared according to the PULS scale. Additionally, patients in both groups were followed postoperatively to assess any infective complication.ResultsThe evaluation comprised 181 patients, 89 for group A and 92 for group B. Overall stone-free rate, clinically insignificant residual fragments, and final stone-free rate were 41.4%, 53.5%, and 95%, respectively. There were 33 (37.1%) patients with ureteral lesions in group A while 42 (45.6%) patients had ureteral lesions in group B, with no significant difference. On the other hand, the overall presence of postoperative infection rate was much higher for Group A (37.1% vs 16.3% P=.03).ConclusionsUAS insertion does not result in a higher number of ureteral injuries. UAS insertion during RIRS allows a lower rate of postoperative infections. (AU)

RESUMO

We investigated the effects of short-term oxygenation changes upon the neuromuscular respiratory drive (airway occlusion pressure [P0.1]), minute ventilation (VE), and respiratory rate (RR) in 12 acute lung injury patients undergoing pressure support ventilation. We ventilated the patients first at a high level (H1) of oxygenation, then at intermediate (I), at low, and again at the high (H2) level. The H1 and H2 periods showed no differences. In the H1, I, and L periods, PaO2 was 158 +/- 68, 75 +/- 12, and 55 +/- 6 mm Hg, respectively. Decreasing oxygenation caused very significant increases in VE, RR, and P0.1. Differences in RR, VE, and rapid shallow breathing index were significant at step H1 versus I. Changes in P0.1 appeared to be higher when the H1 value was higher than normal. An arterial oxygenation target higher than the generally accepted 60 mm Hg level may decrease both RR and VE.

RESUMO

The importance of non-malignant pleural fibrosis in asbestosis in relation to respiratory function is still open to debate because of the differing results obtained in studies of different population groups. In the present study we selected 50 subjects with occupational exposure to asbestos presenting mono- or bilateral pleural fibrosis at X-ray but without lung impairment. Each subject underwent bronchial lavage and ventilatory function tests. The subjects were divided into 4 groups on the basis of the degree of pleural alterations according to the ILO Classification of Pneumoconioses. The results revealed that the mean values of CV and FEV1 in each group were within physiological limits. Moreover, analysis of the type of lung function showed a normal situation in 64% and restricted function in 28% of the cases. The prevalence of the latter finding was not correlated to the severity of pleural fibrosis in the various groups. Also, comparison between severity of pleural fibrosis and number of asbestos bodies/ml of BAL liquid on the one hand and frequency of alveolitis on the other did not reveal any relationship. Therefore, the onset of pleural fibrosis appears to be independent of the quantity of inhaled asbestos fibres and due to different mechanisms from those leading to lung fibrosis. In practice, a correct interpretation of the presence of pleural fibrosis from a clinical and prognostic viewpoint also requires other investigations such as BAL and a complete respiratory function study.

RESUMO

The authors discuss the feasibility of using ultrasonography in the early diagnosis of congenital dysplasia of the hip. Having used the methods of Graf and Harcke, they devised a new scan which always reveals the state of the limbus in neonatal congenital dysplasia. This has been used for two years as an additional technique in neonates with a positive Ortolani click to demonstrate the presence of an inverted limbus, which is not revealed in the Graf and Harcke scans although they give a very good overall picture of the femoral head and acetabulum. The disclosure of an inverted limbus at this early stage is of crucial importance in determining the correct treatment to be adopted.
