ICI discussed a versatile foam technology based on MDI that reportedly can be tailored to meet car makers' requirements - from durable, low-density foams for North America, to high-density comfort foams for thinner seat cushions in Europe, and high-resilience foams specified in Japan.
Pain arising from other organs may be felt in the back. This is called referred pain. Many intra-abdominal disorders-such as appendicitis, aneurysms, kidney diseases, bladder infections, pelvic infections and ovarian disorders, amongst others-can cause pain referred to the back. Other skeletal causes of lower back pain include osteomyelitis, sacroiliitis, and osteoporosis vertebral fractures. 2  This pain is often worse at night and when sitting or standing for a long time. 3  Tumours, possibly cancerous, can be a source of skeletal pain in the back.
Mid-abdominal pain has many causes. Mid-abdominal pain may arise for a variety of reasons. Many organs and bodily systems are contained within or near the abdomen, so pinpointing the exact cause of pain can be challenging. The American Academy of Family Physicians outlines causes of mid-abdominal pain that include dysfunction within the heart, gallbladder, pancreas, stomach, blood vessels, colon, reproductive organs or kidneys. Some abdominal pain-causing conditions may resolve on their own.
