The observations of the following may indicate lower estrogen levels: little pubic hair, loss of the labial fat pad, thinning and resorption of the labia minora, and the narrowing of the vaginal opening. An internal exam will reveal the presence of low vaginal muscle tone, the lining of the vagina appears smooth, shiny, pale with loss of folds. The cervical fornices may have disappeared and the cervix can appear flush with the top of the vagina. Inflammation is apparent when the vaginal lining bleeds easily and appears swollen. The vaginal pH will be measured at 4.5 and higher. Treatment
Symptoms of genitourinary syndrome of menopause (GSM) will unlikely be resolved without treatment. Women may have many or a few symptoms so treatment is provided that best suits each woman. If other health problems are also present, these can be taken into account when determining the best course of treatment. For those who have symptoms related to sexual activities, a lubricant may be sufficient. If both urinary and genital symptoms exist, local, low-dose estrogen therapy can be effective. Those women who are survivors of hormone-sensitive cancer may need to be treated more cautiously. Some women can have symptoms that are widespread and may be at risk for osteoporosis. Estrogen and adjuvants may be best.Topical treatment with estrogen is effective when the symptoms are severe and relieves the disruption in pH to restore the microbiome of the vagina. When symptoms include those related to the urinary system, systematic treatment can be used.
Serotonin syndrome has occurred in patients receiving concurrent antidepressant therapy with selective serotonin reuptake inhibitors (SSRIs) or monoamine oxidase inhibitors, or other medication types (see Interactions below). Convulsive seizures sometimes observed in patients receiving parenteral pethidine on a chronic basis have been attributed to accumulation in plasma of the metabolite norpethidine (normeperidine). Fatalities have occurred following either oral or intravenous pethidine overdose. Interactions
Pethidine has serious interactions that can be dangerous with monoamine oxidase inhibitors (e.g., furazolidone, isocarboxazid, moclobemide, phenelzine, procarbazine, selegiline, tranylcypromine). Such patients may suffer agitation, delirium, headache, convulsions, and/or hyperthermia. Fatal interactions have been reported including the death of Libby Zion. Seizures may develop when tramadol is given intravenously following, or with, pethidine. It can interact as well with SSRIs and other antidepressants, antiparkinson agents, migraine therapy, stimulants and other agents causing serotonin syndrome. It is thought to be caused by an increase in cerebral serotonin concentrations. It is probable that pethidine can also interact with a number of other medications, including muscle relaxants, benzodiazepines, and ethanol. Mechanism of action
Like morphine, pethidine exerts its analgesic effects by acting as an agonist at the μ-opioid receptor.Pethidine is often employed in the treatment of postanesthetic shivering. The pharmacologic mechanism of this antishivering effect is not fully understood, but it may involve the stimulation of κ-opioid receptors.Pethidine has structural similarities to atropine and other tropane alkaloids and may have some of their effects and side effects. In addition to these opioidergic and anticholinergic effects, it has local anesthetic activity related to its interactions with sodium ion channels.
