Cystic fibrosis (CF) related diabetes is an increasingly common comorbidity in CF patients, with scarce data on end-stage complications in the CF population. We report the case of a 32-year-old with poorly controlled diabetes presenting with sub-acute leg pain and focal quadriceps tenderness. Neuromuscular testing and extensive workup revealed diabetic myonecrosis. To our knowledge, this is the first reported case of diabetic myonecrosis in a patient with CF, and highlights the need for pulmonary physicians to recognize this diabetic complication in CF patients, which is associated with a poor long-term prognosis and existing microvascular complications.

Conventional sputum suctioning is a routine clinical practice, but complications may arise from the blind manipulation of the catheter. Recently, a visual sputum suctioning system (VSSS) was developed, and we tested this new system in a laboratory setting. ⋯ Sputum suctioning with the VSSS was feasible. Because of its real-time imaging guidance, the efficiency of the VSSS procedure was greater than that of the conventional single-lumen catheter. Therefore, this system may provide a new platform for sputum suctioning.

Hernia is defined as the protrusion of a totally or partially displaced organ from its normal visceral cavity. Most hernias occur at the level of the abdominal wall, because of a muscular defect. ⋯ We present a 64-year-old patient who developed a spontaneous pulmonary hernia after a severe coughing episode. We describe the clinical features, diagnosis, and successful treatment.

Most portable bi-level positive airway pressure devices are not equipped with air-oxygen blenders for precisely regulating oxygen concentrations, and supplemental oxygen must be added to increase the F(IO2). Very few studies have investigated the factors that affect F(IO2), and their conclusions have been inconsistent. We investigated in vitro noninvasive ventilation (NIV) parameters and their effects on F(IO2), particularly the effect of the oxygen injection site. ⋯ The oxygen injection site had the greatest effect on F(IO2) during NIV.
