Underwater versus conventional EMR of large nonpedunculated colorectal lesions: a multicenter randomized controlled trial.

Background And Aims: Underwater EMR (UEMR) is an alternative procedure to conventional EMR (CEMR) to treat large, nonpedunculated colorectal lesions (LNPCLs). In this multicenter, randomized controlled clinical trial, we aimed to compare the efficacy and safety of UEMR versus CEMR on LNPCLs.

Methods: We conducted a multicenter, randomized controlled clinical trial from February 2018 to February 2020 in 11 hospitals in Spain.

Laryngotracheal separation in neonatal brainstem dysfunction.

Introduction: Neonatal brainstem dysfunction (NBD) associates four symptoms of variable presence and intensity: suction-swallowing dysfunction, abnormal laryngeal sensitivity and motility, gastroesophageal reflux, and cardiac vagal overactivity.

Materials And Methods: We report three cases of severe NBD with chronic aspiration which required surgical management. Successive failures and clinical deterioration led us to perform laryngotracheal separation.

[Clinic-pathologic pattern and survival range in resectable gastric carcinoma].

The present retrospective study evaluated 180 patients with resectable (Group I ) and 128 patients with unresectable (Group II) gastric carcinoma at Belen Hospital, Trujillo, Peru, from 1966 to 1998, with the aim to identify the clinical and pathological features, actuarial survival rate and surgical morbidity and mortality rates of both groups. The mean age of the total series was of 58.3 + 14.

[Prospective etiologic survey on apparently primary nonobstructive myocardiopathies in adults. 57 cases, excluding ischemic cardiopathies].

A prospective study into the aetiology of presumed primary non-obstructive cardiomyopathy was carried out in 57 patients who had no lesions of the trunk of the coronary artery; one case of haemochromatosis and one of amyloidosis were found. Excluding these two cases of cardiomyopathy which were in fact secondary, most of the others were associated with manifestations or with complications of myocardial diseases (two pulmonary emboli and one case of jaundice) or pathology associated with it. Investigation into possible infection, biochemical abnormalities and dietary indiscretion (alcohol, colza oil), were unfruitful.
