A naturalistic philosophy. Secular humanism is philosophically naturalistic. It holds that nature (the world of everyday physical experience) is all there is, and that reliable knowledge is best obtained when we query nature using the scientific method.
Cerebrospinal fluid rhinorrhea (CSF leaking out of the nose) following a traumatic injury is classified as immediate (within 48 hours) or delayed. Of patients with delayed CSF leaks, 95% present within 3 months after the injury. Most patients with an injury causing CSF leaks are identified within 48 hours.
The inner lining of the nose consists of mucus membrane that contains mucus-secreting glands. Mucus is a thin secretion made up of water, antibodies and proteins. The mucus helps to keep the nasal passages moist and prevent dust or infective particles suspended in the air from reaching the lungs. In some conditions, the mucus production increases and manifests in the form of a running nose.
