BACKGROUND
Conversion disorders comprise many clinical pictures, including hysterical mutism. Hysterical mutism has emerged as a clinical entity that remains difficult to diagnose, and whose treatment is poorly codified. Hysterical mutism is a disorder of the vocal function without changing the integrity of the body, resulting in loss of voice. Identified at all times, hysterical mutism entered the medical field in the late nineteenth century, under the direction of Jean-Martin Charcot (Salpêtrière School). Since then, although the disorder has emerged as a clinical entity, it remains little known.
METHOD
A systematic review of the literature. We performed electronic literatures search of relevant studies using Medline, SUDOC, and BIUM. Search terms used were mutism, functional aphonia, conversion disorder, hysteria.
RESULTS
The epidemiology of hysterical mutism is difficult to assess. The first limitation is the lack of consensensual diagnostic criteria. An estimate of its frequency may be advanced through registries consultation of otolaryngology-head and neck surgery. Through a literature review, emerges a rare disorder, about 5% of functional dysphonia. The sex-ratio is in favour of women. Regarding age of onset of disorder, functional aphonia mainly concerns adults with an average around the age of 30-40 years. The onset of the disorder typically involves a sudden onset and a recent stressful event. The duration of the disorder is difficult to specify. It appears that this dysfunction is rapidly reversible and that the majority of patients are in remission of this disorder within three months. The recurrence of dysfunction seems to be frequent. The existence of psychiatric comorbidity did not appear to be the rule. The natural history of this disorder is not known making it tricky to evaluate the efficiency of therapeutic approaches.
CONCLUSION
Today the term hysterical mutism does not appear as an entity in either international classification. It belongs to the category of conversion disorder in the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR). Identified as a medical entity described by the school of the Salpêtrière, this disorder has raised little interest. The medicalization of the condition remains difficult because of the importance of stigma associated with it, which contributes to the rejection rather than support of patients with mutism. To better understand this disorder and improve the care of patients who suffer, renewed interest is warranted.

Review
As a further step towards the modernization of acupuncture, the objective of this review was to figure out the frequency and severity of adverse complications and events in acupuncture treatment reported from 1980 to 2013 in China. All first-hand case reports of acupuncture-related complications and adverse events that could be identified in the scientific literature were reviewed and classified according to the type of complication and adverse event, circumstance of the event, and long-term patient outcome. The selected case reports were published between 1980 and 2013 in 3 databases. Relevant papers were collected and analyzed by 2 reviewers. Over the 33 years, 182 incidents were identified in 133 relevant papers. Internal organ, tissue, or nerve injury is the main complications of acupuncture especially for pneumothorax and central nervous system injury. Adverse effects also included syncope, infections, hemorrhage, allergy, burn, aphonia, hysteria, cough, thirst, fever, somnolence, and broken needles. Qualifying training of acupuncturists should be systemized and the clinical acupuncture operations should be standardized in order to effectively prevent the occurrence of acupuncture accidents, enhance the influence of acupuncture, and further popularize acupuncture to the rest of the world.
