There is notable variation in such estimates based on how one defines the problem, in particular whether one studies people presenting with symptoms vs. measurable median neuropathy (IMNCT) whether or not people are seeking care. It accounts for about 90% of all nerve compression syndromes. The best data regarding IMNCT and CTS comes from population-based studies, which demonstrate no relationship to gender, and increasing prevalence (accumulation) with age. Symptoms
The characteristic symptom of CTS is numbness, tingling, or burning sensations in the thumb, index, middle, and radial half of the ring finger. These areas process sensation through the median nerve. Numbness or tingling is usually worse with sleep. People tend to sleep with their wrists flexed, which increases pressure on the nerve. Ache and discomfort may be reported in the forearm or even the upper arm, but its relationship to IMNCT is uncertain. Symptoms that are not characteristic of CTS include pain in the wrists or hands, loss of grip strength, minor loss of sleep, and loss of manual dexterity.Median nerve symptoms may arise from compression at the level of the thoracic outlet or the area where the median nerve passes between the two heads of the pronator teres in the forearm, although this is debated. Signs
Severe IMNCT is associated with measurable loss of sensibility. Diminished threshold sensibility (the ability to distinguish different amounts of pressure) can be measured using Semmes-Weinstein monofilament testing.
A vaginal septum is a vaginal anomaly that is partition within the vagina; such a septum could be either longitudinal or transverse. In some affected women, the septum is partial or does not extend the length or width of the vagina. Pain during intercourse can be a symptom. A longitudinal vaginal septum develops during embryogenesis when there is an incomplete fusion of the lower parts of the two Müllerian ducts. As a result, there may appear to be two openings to the vagina. There may be associated duplications of the more cranial parts of the Müllerian derivatives, a double cervix, and either a uterine septum or uterus didelphys (double uterus). A transverse septum forms during embryogenesis when the Müllerian ducts do not fuse to the urogenital sinus. A complete transverse septum can occur across the vagina at different levels. Menstrual flow can be blocked, and is a cause of primary amenorrhea. The accumulation of menstrual debris behind the septum is termed cryptomenorrhea. Some transverse septa are incomplete and may lead to dyspareunia or obstruction in labour. See also
