Digital thoracic drainage: a new system to monitor air leaks in pediatric population

Introduction

New digital thoracic drainage systems allow an objective measurement of air leakage. They have proven their usefulness in the postoperative thoracic surgery in adults, but there is little experience with its use in the pediatric population. The objective of our study is to analyze their safety and effectiveness in the postoperative period of the pediatric patients.

Denosumab‐induced cutaneous hypersensitivity reaction with distinct clinical and histopathologic findings

Cutaneous reactions from targeted biologics are increasingly common. We describe a case of a cutaneous lichenoid drug eruption from the RANK inhibitor denosumab and a previously unreported lymphohistiocytic reaction pattern. The clinical and histopathological details of this case will aid in recognition, diagnosis, and treatment of drug rashes from denosumab.     

Abnormal electrocardiogram in a patient with amyotrophic lateral sclerosis mimicking myocardial ischaemia

Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disorder that almost exclusively involves motor neurons although autonomic dysfunction has also been reported. We present an 84-year-old female with no documented history of heart disease, who was admitted with negative T waves in the electrocardiogram precordial leads mimicking myocardial ischaemia. No other abnormalities were shown in the rest of the cardiologic evaluation, suggesting autonomic nervous system dysfunction. A neurophysiological study demonstrated acute and chronic denervation in multiple muscles with normal nerve conduction studies, confirming ALS diagnosis. Previous studies have shown that subclinical sympathetic hyperfunction and parasympathetic hypofunction might result in cardiovascular dysfunction in ALS patients. It is important to detect disturbances of autonomic cardiac control because this dysfunction may influence survival and quality of life, leading to a decrease in life expectancy in ALS patients. This Case Report may support the impairment of cardiac autonomic control in patients with ALS.
