A 2016 systematic review suggests better evidence among those with frequent tension headaches, but concludes that further trials comparing acupuncture with other treatment options are needed.People with tension-type headache often use spinal manipulation, soft tissue therapy, and myofascial trigger point treatment. Studies of effectiveness are mixed. A 2006 systematic review found no rigorous evidence supporting manual therapies for tension headache. A 2005 structured review found only weak evidence for the effectiveness of chiropractic manipulation for tension headache, and that it was probably more effective for tension headache than for migraine. A 2004 Cochrane review found that spinal manipulation may be effective for migraine and tension headache, and that spinal manipulation and neck exercises may be effective for cervicogenic headache. Two other systematic reviews published between 2000 and May 2005 did not find conclusive evidence in favor of spinal manipulation. A 2012 systematic review of manual therapy found that hands-on work may reduce both the frequency and the intensity of chronic tension-type headaches. More current literature also appears to be mixed however, CTTH patients may benefit from massage and physiotherapy as suggested by a systemic review examining these modalities via RCTs specifically for this patient population Despite being helpful, the review also makes a point to note that there is no difference in effectiveness long term (6 months) between those CTTH patients utilizing TCAs and physiotherapy. Another systemic review comparing manual therapy to pharmacologic therapy also supports little long term difference in outcome regarding TTH frequency, duration, and intensity.
Mayer-Rokitansky-Küster-Hauser syndrome (MRKH syndrome), also known as Müllerian agenesis, Müllerian aplasia, or vaginal agenesis is a congenital malformation characterized by a failure of the Müllerian duct to develop, resulting in a missing uterus and variable degrees of vaginal hypoplasia of its upper portion. Müllerian agenesis (including absence of the uterus, cervix and/or vagina) is the cause in 15% of cases of primary amenorrhoea. Because most of the vagina does not develop from the Müllerian duct, instead developing from the urogenital sinus, along with the bladder and urethra, it is present even when the Müllerian duct is completely absent. Because ovaries do not develop from the Müllerian ducts, affected people might have normal secondary sexual characteristics but are infertile due to the lack of a functional uterus. However, parenthood is possible through use of gestational surrogates. Mayer–Rokitansky–Küster–Hauser syndrome is hypothesized to be a result of autosomal dominant inheritance with incomplete penetrance and variable expressivity, which contributes to the complexity involved in identifying of the underlying mechanisms causing the condition. Because of the variance in inheritance, penetrance and expressivity patterns, MRKH is subdivided into two types: type 1, in which only the structures developing from the Müllerian duct are affected (the upper vagina, cervix, and uterus), and type 2, where the same structures are affected, but is characterized by the additional malformations of other body systems most often including the renal and skeletal systems. MRKH type 2 includes MURCS (Müllerian Renal Cervical Somite).
