Esophageal cancer is the seventh leading cause of cancer death worldwide. Traditional Chinese medicinal herbs are sometimes used as an adjunct to radiotherapy or chemotherapy for this type of cancer. ⋯ There was no evidence of effect of TCM in the treatment of esophageal cancer due to no any authentic RCT in this field yet. New trials should be large scaled, correctly randomised and results assessor blinded in the future.

ReviewWITHDRAWN: Physical therapies for prevention of urinary and faecal incontinence in adults.
Physical therapies, particularly pelvic floor muscle training, have been recommended for prevention of incontinence associated with childbearing, and prostate surgery. ⋯ There is insufficient evidence to determine whether physical therapies can prevent incontinence in childbearing women, or men following prostate surgery. Further, better quality research is needed.

ReviewDrugs for preventing red blood cell dehydration in people with sickle cell disease.
Sickle cell disease is an inherited disorder of haemoglobin, which results in abnormal red blood cells. These can deform and cause blockages in blood vessels, leading to acute crises such as pain; stroke and splenic sequestration; and chronic organ and tissue damage. Recently research has begun to focus on therapies which prevent the red blood cells deforming by reducing the loss of water and ions from the cells. However, little is known about the effectiveness and safety of such drugs. ⋯ While the results of zinc for reducing sickle-related crises are encouraging, larger and longer-term multicentre studies over a number of years are needed to evaluate the effectiveness of this therapy for people with sickle cell disease.

Endometriosis is defined as the presence of endometrial tissue (stromal and glandular) outside the normal uterine cavity. Conventional medical and surgical treatments for endometriosis aim to remove or decrease the deposits of ectopic endometrium. The observation that hyper androgenic states (an excess of male hormone) induce atrophy of the endometrium has led to the use of androgens in the treatment of endometriosis. Danazol is one of these treatments. The efficacy of danazol is based on its ability to produce a high androgen and low oestrogen environment (a pseudo menopause) which results in atrophy of the endometriotic implants and thus an improvement in painful symptoms. ⋯ Danazol is effective in treating the symptoms and signs of endometriosis. However, its use is limited by the occurrence of androgenic side effects.

Intermittent claudication (IC) is pain caused by chronic occlusive arterial disease, that develops in a limb during exercise and is relieved with rest. Buflomedil is a vasoactive agent used to treat peripheral vascular disease. However, its clinical efficacy for IC has not yet been critically examined. ⋯ There is little evidence available to evaluate the efficacy of buflomedil for IC. Most trials were excluded due to poor quality. The two included trials showed moderately positive results; these are undermined by publication bias since we know of at least another four unpublished, irretrievable, and inconclusive studies.Buflomedil's benefit is small in relation to safety issues and its narrow therapeutic range.
