Changes in sensation can start as pins and needles leading to numbness. Changes in bladder function may be changes to stream or inability to fully empty the bladder. If a person progresses to full retention intervention is less likely to be successful. Management
The management of true cauda equina syndrome frequently involves surgical decompression. When cauda equina syndrome is caused by a herniated disk early surgical decompression is recommended.Sudden onset cauda equina syndrome is regarded as a medical/surgical emergency. Surgical decompression by means of laminectomy or other approaches may be undertaken within 6, 24 or 48 hours of symptoms developing if a compressive lesion (e.g., ruptured disc, epidural abscess, tumor or hematoma) is demonstrated. Early treatment may significantly improve the chance that long-term neurological damage will be avoided.Surgery may be required to remove blood, bone fragments, a tumor or tumors, a herniated disc or an abnormal bone growth. If the tumor cannot be removed surgically and is malignant then radiotherapy may be used as an alternative to relieve pressure. Chemotherapy can also be used for spinal neoplasms. If the syndrome is due to an inflammatory condition e.g., ankylosing spondylitis, anti-inflammatory, including steroids can be used as an effective treatment. If a bacterial infection is the cause then an appropriate course of antibiotics can be used to treat it.Cauda equina syndrome can occur during pregnancy due to lumbar disc herniation. The risk of cauda equina syndrome during pregnancy increases with age of the mother. Surgery can still be performed and pregnancy does not adversely affect treatment.
Hairy leukoplakia  is a white patch on the side of the tongue with a corrugated or hairy appearance. It is caused by Epstein-Barr virus (EBV) and occurs usually in persons who are immunocompromised, especially those with human immunodeficiency virus infection/acquired immunodeficiency syndrome (HIV/AIDS). The white lesion, which cannot be scraped off, is benign and does not require any treatment, although its appearance may have diagnostic and prognostic implications for the underlying condition. Depending upon what definition of leukoplakia is used, hairy leukoplakia is sometimes considered a subtype of leukoplakia, or a distinct diagnosis. Signs and symptoms
There are no symptoms associated with the lesion itself, although many and varied symptoms and signs may be associated with the underlying cause of immunosuppression. The lesion is a white patch, which almost exclusively occurs on the lateral surfaces of the tongue, although rarely it may occur on the buccal mucosa, soft palate, pharynx or esophagus. The lesion may grow to involve the dorsal surface of the tongue. The texture is vertically corrugated ("hairy") or thickly furrowed and shaggy in appearance. Causes
The white appearance is created by hyperkeratosis (overproduction of keratin) and epithelial hyperplasia. The causative agent implicated is Epstein-Barr virus, the same virus that causes infectious mononucleosis (glandular fever). After the primary EBV infection has been overcome, the virus will persist for the rest of the hosts life and "hides" from the immune system by latent infection of B lymphocytes.
