Piriformis Syndrome. Piriformis syndrome causes pain in the buttock which may radiate down the leg. It is due to the sciatic nerve being impinged by a tight piriformis muscle deep in the buttocks.he piriformis muscle is one of the small muscles deep in the buttocks that rotates the leg outwards. It runs from the sacrum bone at the bottom of the spine and attaches to the thigh bone or femur roughly near the outside crease of the buttocks.
A pneumothorax occurs when some of the tiny air sacs (alveoli) in a baby's lung become overinflated and burst. This causes air to leak into the space between the lung and chest wall (pleural space). The most common cause of pneumothorax is respiratory distress syndrome. This is a condition that occurs in babies who are born too early (premature). The baby's lungs lack the slippery substance (surfactant) that helps them stay open. Therefore, the tiny air sacs are not able to expand as easily.
