In China, traditional treatment based on the causes suggested by cultural beliefs are administrated to the patient. Praying to gods and asking Taoist priests to perform exorcism is common. If a fox spirit is believed to be involved, people may hit gongs or beat the person to drive it out. The person will receive a yang- or yin-augmenting Chinese medicine potion, usually including herbs, pilose antler (stag of deer) or deer tail, and tiger penis, deer penis, or fur seal penis. Other foods for therapy are pepper soup, ginger soup and liquor.
In historical culture-bound cases, reassurance and talks on sexual anatomy are given. Patients are treated with psychotherapy distributed according to symptoms and to etiologically significant points in the past. Prognosis appears to be better in cases with a previously functional personality, a short history and low frequency of attacks, and a relatively uncomplicated sexual life.
For sporadic Western cases, careful diagnostic workup including searching for underlying sexual conflict is common. The choice of psychotherapeutic treatment is based on the psychiatric pathology found.
Some drugs such as trazodone may cause priapism as a side effect, in which case discontinuing the medication may give relief. Additionally, the condition can sometimes start only after the discontinuation of SSRIs. In some recorded cases, the syndrome was caused by or can cause a pelvic arterial-venous malformation with arterial branches to the penis or clitoris; surgical treatment was effective in this case.
In other situations where the cause is unknown or less easily treatable, the symptoms can sometimes be reduced by the use of antidepressants, antiandrogenic agents, and anaesthetising gels. Psychotherapy with cognitive reframing of the arousal as a healthy response may also be used.
More recently, the symptoms of the condition have also been linked with pudendal nerve entrapment. Regional nerve blocks and less common surgical intervention have demonstrated varying degrees of success in most cases. There is, however, no evidence for the long-term efficacy of surgical intervention.
In one recent case, serendipitous relief of symptoms was noted from treatment with varenicline, a treatment for nicotine addiction.
Just as with erectile dysfunction in men, lack of sexual function in women may be treated with hormonal patches or tablets to correct hormonal imbalances, clitoral vacuum pump devices and medication to improve blood flow, sexual sensation and arousal.
Many practitioners today treat both men and women who have SSRI-induced anorgasmia with sildenafil, more commonly known as Viagra. While this approach is known to work well in men with sexual dysfunction, it is only recently that the effectiveness of sildenafil in women with sexual dysfunction is coming to light. A recent study by H. G. Nurnberg et al. showed a complete or very significant reversal of their sexual dysfunction upon taking sildenafil one hour prior to sexual activity. In this study, eight out of the nine women required 50 mg of sildenafil while the 9th woman required 100 mg of sildenafil.
Another option for women who have SSRI-induced anorgasmia is the use of vardenafil. Vardenafil is a type 5 phosphodiesterase (PDE5) inhibitor that facilitates muscle relaxation and improves penile erection in men. However, there is much controversy about the efficiency of the drug used in the reversal of female sexual dysfunction. Vardenafil is similar to sildenafil, but vardenafil is less expensive and may be covered under some insurance plans. A study by A.K. Ashton M.D. has shown that in the case of one particular woman, the effects of vardenafil as opposed to sildenafil have not only been comparable in the effectiveness, but that vardenafil is cheaper and reversal of sexual dysfunction requires a smaller dose. So far, vardenafil has been approved by the Food and Drug administration only for use in men.
The NIH states that yohimbine hydrochloride has been shown in human studies to be possibly effective in the treatment of male impotence resulting from erectile dysfunction or SSRI usage (e.g., anorgasmia). Published reports have shown it to be effective in the treatment of orgasmic dysfunction in men.
Cabergoline, an agonist of dopamine D₂ receptors which inhibits prolactin production, was found in a small study to fully restore orgasm in one third of anorgasmic subjects, and partially restore orgasm in another third. Limited data has shown that the drug amantadine may help to relieve SSRI-induced sexual dysfunction. Cyproheptadine, buspirone, stimulants such as amphetamines (including the antidepressant bupropion), nefazodone and yohimbine have been used to treat SSRI-induced anorgasmia. Reducing the SSRI dosage may also resolve anorgasmia problems.
Testosterone has been used to successfully treat undervirilization in some but not all men with PAIS, despite having supraphysiological levels of testosterone to start with. Treatment options include transdermal gels or patches, oral or injectable testosterone undecanoate, other injectable testosterone esters, testosterone pellets, or buccal testosterone systems. Supraphysiological doses may be required to achieve the desired physiological effect, which may be difficult to achieve using non-injectable testosterone preparations. Exogenous testosterone supplementation in unaffected men can produce various unwanted side effects, including prostatic hypertrophy, polycythemia, gynecomastia, hair loss, acne, and the suppression of the hypothalamic-pituitary-gonadal axis, resulting in the reduction of gonadotropins (i.e., luteinizing hormone and follicle-stimulating hormone) and spermatogenic defect. These effects may not manifest at all in men with AIS, or might only manifest at a much higher concentration of testosterone, depending on the degree of androgen insensitivity. Those undergoing high dose androgen therapy should be monitored for safety and efficacy of treatment, possibly including regular breast and prostate examinations. Some individuals with PAIS have a sufficiently high sperm count to father children; at least one case report has been published that describes fertile men who fit the criteria for grade 2 PAIS (micropenis, penile hypospadias, and gynecomastia). Several publications have indicated that testosterone treatment can correct low sperm counts in men with MAIS. At least one case report has been published that documents the efficacy of treating a low sperm-count with tamoxifen in an individual with PAIS.
XX males are sterile due to low or no sperm content and there is currently no treatment to address this infertility. Genital ambiguities, while not necessary to treat for medical reasons, can be treated through the use of hormonal therapy, surgery, or both. Since XX male syndrome is variable in its presentation, the specifics of treatment varies widely as well. In some cases gonadal surgery can be performed to remove partial or whole female genitalia. This may be followed by plastic and reconstructive surgery to make the individual appear more externally male. Conversely, the individual may wish to become more feminine and feminizing genitoplasty can be performed to make the ambiguous genitalia appear more female. Hormonal therapy may also aid in making an individual appear more male or female.
The condition may be treated with surgery. There are several different techniques to treat this condition. Threading a suture through the lower membrane, and then tying a tight knot around the frenulum itself is a procedure that minimises invasive action. After a few days the frenulum will weaken and eventually break apart to allow the prepuce to fully retract. Other procedures involve the cutting of the skin and require the use of sutures to help in the healing process. Stretching exercises and steroid creams may also be helpful. Alternatively, it may be treated by a reparative plastic surgery operation called a frenuloplasty, or by complete circumcision including resection of the frenulum (frenectomy).
Surgical methods range from the complete removal of the foreskin to more minor operations to relieve foreskin tightness:
- Dorsal slit (superincision) is a single incision along the upper length of the foreskin from the tip to the corona, exposing the glans without removing any tissue.
- Ventral slit (subincision) is an incision along the lower length of the foreskin from the tip of the frenulum to the base of the glans, removing the frenulum in the process. Often used when frenulum breve occurs alongside the phimosis.
- Preputioplasty, in which a limited dorsal slit with transverse closure is made along the constricting band of skin, can be an effective alternative to circumcision. It has the advantage of only limited pain and a short time of healing relative to circumcision, and avoids cosmetic effects.
- Circumcision is sometimes performed for phimosis, and is effective, but this was becoming less common as of 2012.
While circumcision prevents phimosis, studies of the incidence of healthy infants circumcised for each prevented case of phimosis are inconsistent.
Genitoplasty, unlike gender assignment, can be irreversible, and there is no guarantee that adult gender identity will develop as assigned despite surgical intervention. Some aspects of genitoplasty are still being debated; a variety of different opinions have been presented by professionals, self-help groups, and patients over the last few decades. Points of consideration include what conditions justify genitoplasty, the extent and type of genitoplasty that should be employed, when genitoplasty should be performed, and what the goals of genitoplasty should be. Gender assignment itself does not predicate the need for immediate genitoplasty; in some cases, surgical intervention can be delayed to allow the affected child to reach an age and maturity sufficient to have a role in such decisions. Some studies suggest that early surgeries can still produce satisfactory outcomes, while others suggest it to be unlikely. Even surgeries that are planned as one-stage procedures often require further major surgery. Scarring and tissue loss that result from repeated surgical procedures are of particular concern, due to the presumed negative impact on sexual function.
While it is thought that feminizing genitoplasty typically requires fewer surgeries to achieve an acceptable result and results in fewer urologic difficulties, there is no evidence that feminizing surgery results in a better psychosocial outcome. In one study, individuals with grade 3 PAIS who were raised male rated their body image and sexual function similarly to those who were raised female, even though they were more likely to have genitalia that were abnormal in size and appearance; more than half of the male participants had a stretched penile length that was below 2.5 standard deviations of the mean, while only 6% of female participants presented with a short vagina in adulthood, and participating physicians gave a lower cosmetic rating to the surgical results of the men than the women. Both male and female participants cited the appearance of their genitalia as being the greatest contributing factor to their dissatisfaction with their body image. In two larger studies, the common predictor of gender reassignment was stigmatization related to having an intersex condition.
The outcome of masculinizing genitoplasty is dependent on the amount of erectile tissue and the extent of hypospadias. Procedures include correction of penile curvature and chordee, reconstruction of the urethra, hypospadias correction, orchidopexy, and Müllerian remnant removal to prevent infection and pseudo-incontinence. Erectile prosthesis may be inserted in cases of successful neophalloplasty in adulthood, although it has a high morbidity. Additional surgeries may be required to correct postsurgical complications such as stenosis of the anastomosis between the native urethra and the graft, urethral fistulas, and posterior displacement of the balanic meatus. Successful masculinizing genitoplasty performed on individuals with grade 3 PAIS often requires multiple surgeries.
If feminizing genitoplasty is performed in infancy, the result will need to be refined at puberty through additional surgery. Procedures include clitoral reduction / recession, labiaplasty, repair of the common urogenital sinus, vaginoplasty, and vaginal dilation through non-surgical pressure methods. Clitoral reduction / recession surgery carries with it the risk of necrosis as well as the risk of impairing the sexual function of the genitalia, and thus should not be performed for less severe clitoromegaly. Clitoral surgery should be focused on function rather than appearance, with care being taken to spare the erectile function and innervation of the clitoris. If PAIS presents with a common urogenital sinus, the American Academy of Pediatrics currently recommends that surgery to separate the urethra from the vagina be performed at an early age. As is the case for CAIS, vaginal dilation using pressure dilation methods should be attempted before the surgical creation of a neovagina is considered, and neither should be performed before puberty. Complications of feminizing genitoplasty can include vaginal stenosis, meatal stenosis, vaginourethral fistula, female hypospadias, urinary tract injuries, and recurrent clitoromegaly. Successful feminizing genitoplasty performed on individuals with grade 3 PAIS often requires multiple surgeries, although more surgeries are typically required for successful masculinizing genitoplasty in this population.
Many surgical procedures have been developed to create a neovagina, as none of them is ideal. Surgical intervention should be considered only after non-surgical pressure dilation methods have failed to produce a satisfactory result. Neovaginoplasty can be performed using skin grafts, a segment of bowel, ileum, peritoneum, , buccal mucosa, amnion, or dura mater. Success of such methods should be determined by sexual function, and not by vaginal length alone, as has been done in the past. Ileal or cecal segments may be problematic because of a shorter mesentery, which may produce tension on the neovagina, leading to stenosis. The sigmoid neovagina is thought to be self-lubricating, without the excess mucus production associated with segments of small bowel. Vaginoplasty may create scarring at the introitus (the vaginal opening), requiring additional surgery to correct. Vaginal dilators are required postoperatively to prevent vaginal stenosis from scarring. Other complications include bladder and bowel injuries. Yearly exams are required, as neovaginoplasty carries a risk of carcinoma, although carcinoma of the neovagina is uncommon. Neither neovaginoplasty nor vaginal dilation should be performed before puberty.
Physiologic phimosis, common in males 10 years of age and younger, is normal, and does not require intervention. Non-retractile foreskin usually becomes retractable during the course of puberty.
If phimosis in older children or adults is not causing acute and severe problems, nonsurgical measures may be effective. Choice of treatment is often determined by whether circumcision is viewed as an option of last resort to be avoided or as the preferred course.
Treatment depends on the proximate cause. In one study, it was reported that 9 of 13 men who underwent vasectomy reversal in an attempt to relieve post-vasectomy pain syndrome became pain-free, though the followup was only one month in some cases. Another study found that 24 of 32 men had relief after vasectomy reversal.
Nerve entrapment is treated with surgery to free the nerve from the scar tissue, or to cut the nerve. One study reported that denervation of the spermatic cord provided complete relief at the first follow-up visit in 13 of 17 cases, and that the other four patients reported improvement. As nerves may regrow, long-term studies are needed.
One study found that epididymectomy provided relief for 50% of patients with post-vasectomy pain syndrome.
Orchiectomy is recommended usually only after other surgeries have failed.
Autistic enterocolitis is the name of a nonexistent medical condition proposed by discredited British gastroenterologist Andrew Wakefield when he suggested a link between a number of common clinical symptoms and signs which he contended were distinctive to autism. The existence of such an enterocolitis has been dismissed by experts as having "not been established". Wakefield's now-retracted and fraudulent report used inadequate controls and suppressed negative findings, and multiple attempts to replicate his results have been unsuccessful.
Reviews in the medical literature have found no link between the MMR vaccine and autism or with bowel disease.
Most of Wakefield's coauthors later retracted the conclusions of the original paper proposing the hypothesis, and the General Medical Council found Wakefield guilty of manipulating patient data and misreporting results. His work has been exposed as falsified and described as an "elaborate fraud".
Due to its mild presentation, MAIS often goes unnoticed and untreated. Management of MAIS is currently limited to symptomatic management; methods to correct a malfunctioning androgen receptor protein that result from an AR gene mutation are not currently available. Treatment includes surgical correction of mild gynecomastia, minor hypospadias repair, and testosterone supplementation. Supraphysiological doses of testosterone have been shown to correct diminished secondary sexual characteristics in men with MAIS, as well as to reverse infertility due to low sperm count. As is the case with PAIS, men with MAIS will experience side effects from androgen therapy (such as the suppression of the hypothalamic-pituitary-gonadal axis) at a higher dosage than unaffected men. Careful monitoring is required to ensure the safety and efficacy of treatment. Regular breast and prostate examinations may be necessary due to comorbid association with breast and prostate cancers.
There are no treatment to return to its normal functions. However, there are treatments for the different symptoms.
For the Developmental symptoms, Educational intervention and speech therapy beginning in infancy could help to reduce the high risk for motor, cognitive, speech, and language delay
For theSkeletal features, referral to an orthopedist for consideration of surgical release of contractures. In addition,early referral to physical therapy could help increase joint mobility.
Lastly, Thyroid hormone replacement could help out the thyroid dysfunction
Management of AIS is currently limited to symptomatic management; no method is currently available to correct the malfunctioning androgen receptor proteins produced by "AR" gene mutations. Areas of management include sex assignment, genitoplasty, gonadectomy in relation to tumor risk, hormone replacement therapy, genetic counseling, and psychological counseling.
Persistent genital arousal disorder (PGAD), originally called persistent sexual arousal syndrome (PSAS), Weiss Disease, and also known as restless genital syndrome (ReGS or RGS), results in a spontaneous, persistent, and uncontrollable genital arousal, with or without orgasm or genital engorgement, unrelated to any feelings of sexual desire. It was only recently characterized as a distinct syndrome in medical literature with a comparable counterpart increasingly reported by men. It was studied as far back as 1986 and in the 90s was researched by the Dutch.
Some physicians use the term "persistent sexual arousal syndrome" to refer to the condition in women; others consider the syndrome of priapism in men to be the same disorder. Priapism was a recognized, diagnosable medical condition in the "Diagnostic and Statistical Manual of Mental Disorders" IV, whereas PGAD was not. With the release of the DSM-5 in 2013, PGAD was again not included as a listed condition.
In particular, it is not related to hypersexuality, sometimes known as nymphomania or satyriasis. (Hypersexuality, nymphomania, and satyriasis are also not recognized diagnosable medical conditions by the DSM-IV).
The condition is usually self-limiting, and thus not indicated for surgery.
There is no definitive cure for LS. Behavior change is part of treatment. The patient should minimize or preferably stop scratching LS-affected skin. Any scratching, stress or damage to the skin can worsen the disease. Scratching has been theorized to increase cancer risks. Furthermore the patient should wear comfortable clothes and avoid tight clothing, as it is a major factor in the severity of symptoms in some cases.
Topically applied corticosteroids to the LS-affected skin are the first-line treatment for lichen sclerosus in women and men, with strong evidence showing that they are "safe and effective" when appropriately applied, even over long courses of treatment, rarely causing serious adverse effects. They improve or suppress all symptoms for some time, which highly varies across patients, until it is required to use them again. Methylprednisolone aceponate has been used as a safe and effective corticosteroid for mild and moderate cases. For severe cases, it has been theorized that mometasone furoate might be safer and more effective than clobetasol.
Continuous usage of appropriate doses of topical corticosteroids is required to ensure symptoms stay relieved over the patient's life time. If continuously used, corticosteroids have been suggested to minimize the risk of cancer in various studies. In a prospective longitudinal cohort study of 507 women throughout 6 years, cancer occurred for 4.7% of patients who were only "partially compliant" with corticosteroid treatment, while it occurred in 0% of cases where they were "fully compliant". In a second study, of 129 patients, cancer occurred in 11% of patients, none of which were fully compliant with corticosteroid treatment. Both these studies however also said that a corticosteroid as powerful as clobetasol isn't necessary in most cases. In a prospective study of 83 patients, throughout 20 years, 8 patients developed cancer. 6 already had cancer at presentation and had not had treatment, while the other 2 weren't taking corticosteroids often enough. In all three studies, every single cancer case observed occurred in patients who weren't taking corticosteroids as often as the study recommended.
Continuous, abundant usage of emollients topically applied to the LS-affected skin is recommended to improve symptoms. They can supplement but not replace corticosteroid therapy. They can be used much more frequently than corticosteroids due to the extreme rarity of serious adverse effects. Appropriate lubrication should be used every time before and during sex in genital LS in order to avoid pain and worsening the disease. Some oils such as olive oil and coconut oil can be used to accomplish both the emollient and sexual lubrication function.
Recent studies have shown that topical calcineurin inhibitors such as tacrolimus can have an effect similar to corticosteroids, but its effects on cancer risks in LS are not conclusively known.
In males, it has been reported that circumcision can have positive effects, but does not necessarily prevent against further flares of the disease and does not protect against the possibility of cancer. Circumcision does not prevent or cure LS; in fact, "balanitis xerotica obliterans" in men was first reported as a condition affecting a set of circumcised men, by Stühmer in 1928.
A number of features found with Nasodigitoacoustic syndrome can be managed or treated. Sensorineural hearing loss in humans may be caused by a loss of hair cells (sensory receptors in the inner ear that are associated with hearing). This can be hereditary and/or within a syndrome, as is the case with nasodigitoacoustic syndrome, or attributed to infections such as viruses. For the management of sensorineural hearing loss, hearing aids have been used. Treatments, depending upon the cause and severity, may include a pharmacological approach (i.e., the use of certain steroids), or surgical intervention, like a cochlear implant.
Pulmonary, or pulmonic stenosis is an often congenital narrowing of the pulmonary valve; it can be present in nasodigitoacoustic-affected infants. Treatment of this cardiac abnormality can require surgery, or non-surgical procedures like balloon valvuloplasty (widening the valve with a balloon catheter).
There are many treatments and procedures associated with wart removal. A review of clinical trials of various cutaneous wart treatments concluded that topical treatments containing salicylic acid were more effective than placebo. Cryotherapy appears to be as effective as salicylic acid, but there have been fewer trials.
Typically, treatment for this condition requires a team of specialists and surgery. Below are the treatments based on the symptom.
Another product available over-the-counter that can aid in wart removal is silver nitrate in the form of a caustic pencil, which is also available at drug stores. In a placebo-controlled study of 70 patients, silver nitrate given over nine days resulted in clearance of all warts in 43% and improvement in warts in 26% one month after treatment compared to 11% and 14%, respectively, in the placebo group. The instructions must be followed to minimize staining of skin and clothing. Occasionally pigmented scars may develop.
Several randomized, controlled trials have found that zinc sulfate, consumed orally, often reduces or eliminates warts. The zinc sulfate dosage used in medical trials for treatment of warts was between 5 and 10 mg/kg/day. For elemental zinc, a lower dosage of 2.5 mg/kg/day may be appropriate as large amounts of zinc may cause a copper deficiency. Other trials have found that topical zinc sulfate solution or zinc oxide are also effective.
A 2014 study indicates that lopinavir is effective against the human papilloma virus (HPV). The study used the equivalent of one tablet twice a day applied topically to the cervices of women with high-grade and low-grade precancerous conditions. After three months of treatment, 82.6% of the women who had high-grade disease had normal cervical conditions, confirmed by smears and biopsies.
Studies of fat-soluble garlic extracts have shown clearing in greater than 90% of cases. The extract is applied twice daily and covered with an adhesive bandage. Improvements show within 2–4 weeks and total clearing in an average of 6–9 weeks.
Children with CHARGE syndrome may have a number of life-threatening medical conditions; with advances in medical care, these children can survive and can thrive with the support of a multidisciplinary team of medical professionals. Therapies and education must take into consideration hearing impairment, vision problems, and any others. Early intervention, such as occupational, speech-language, and physical therapy, to improve static posture, ambulation, and self-care skills is important. The intelligence of children with multiple health impairments, such as combined deafblindness, can be underestimated in the absence of early intervention.
Anorgasmia, or Coughlan's syndrome, is a type of sexual dysfunction in which a person cannot achieve orgasm despite adequate stimulation. In males, it is most closely associated with delayed ejaculation. Anorgasmia can often cause sexual frustration. Anorgasmia is far more common in females (4.7 percent) than in males and is especially rare in younger men. The problem is greater in women who are post-menopause.
Until the 1970s, autism was rarely accepted to be a distinctive diagnosis, but, following changes to the Diagnostic and Statistical Manual of the American Psychiatric Association it is diagnosed much more often. How much of this increase is due to greater diagnostic vigilance by doctors, changes in diagnostic categories, or an actual increase in prevalence, remains unclear. Late-onset autism cases are estimated at 25% and reported by sources including the "British Medical Journal" as not having changed in recent years.
Despite others describing common bowel features, there have been no peer reviewed studies yet published, as of 2006, corroborating the existence of "autistic enterocolitis"; other studies have explicitly refuted its existence. Thus, it is not generally accepted that the types of colitis diagnosed in autistic individuals are either unique to autism, or more common in autistic people than in the general population.
