Abstract

Figure 1: Blue sclera in osteogenesis imperfecta (OI), a rare, genetically inherited syndrome involving connective tissue, resulting in anatomic and physiologic abnormalities. ¹

^{Figure 2: Double row of upper incisors may cause difficult intubation2}

^{Figure 3: ‘Love-sign’ hernia; bilateral inguinal hernia, associated in this child with diaphragmatic hernia. One congenital anomaly; you must search for other associated anomalies}

Figure 4: Endotest by Portex; for checking endotracheal tube cuff pressure. Permissible upper limit is around 30 cmH₂O, which is capillary pressure in tracheal mucosa. Excessive pressure may be a source of postextubation cough, but it is definitely linked to subglottic stenosis due to ischemic changes.
