The presentation and long-term therapeutic responses of PRL-secreting pituitary tumors in men have been only partially studied. Gender-specific differences in tumor size at clinical presentation and possible differences in tumor biology in men compared to women make it important to determine treatment outcomes of male patients with prolactinomas. We performed a retrospective review of men with prolactinomas medically managed at Massachusetts General Hospital between 1980 and 1997. We identified 46 male patients with prolactinomas managed with medical therapy alone. Twelve patients had microadenomas, defined as a serum PRL level greater than 15 ng/mL and a normal pituitary scan or a tumor smaller than 1 cm. Thirty-four patients had macroprolactinomas, defined by a serum PRL greater than 200 ng/mL and pituitary adenoma larger than 1 cm. Bromocriptine, quinagolide, and/or cabergoline were administered as medical therapy. All patients had at least one follow-up visit, and the most recent serum PRL measurement after initiating dopamine agonist therapy was reported. Baseline clinical characteristics for patients with macroprolactinomas and microprolactinomas showed a larger proportion of patients with macroprolactinomas reporting a history of headache (74% vs. 0%), whereas the prevalence of sexual dysfunction and testosterone deficiency was similar between the two groups. Median serum PRL at presentation was 99 ng/mL (range, 16-385 ng/mL) vs. 1,415 ng/mL (range, 387-67,900 ng/mL), in the microprolactinoma and macroprolactinoma groups, respectively. A normal PRL level was achieved in a similar percentage of men with microprolactinomas vs. macroprolactinomas (83% vs. 79%, respectively). Although the majority of patients in both groups were treated with bromocriptine, a comparable number of patients with microprolactinomas vs. macroprolactinomas achieved a normal PRL level with cabergoline therapy. The response rates for bromocriptine and cabergoline were similar in both groups. No patient with a microprolactinoma required hormone replacement therapy, in contrast to patients with macroprolactinomas, who required thyroid, testosterone, and/or glucocorticoid replacement therapy. No patient had evidence of an increase in tumor size during therapy. In summary, we investigated the clinical presentation and treatment outcome in men with prolactinomas. We found that normalization of serum PRL levels occurs in approximately 80% of men with prolactinomas. Of importance, dopamine agonist administration yielded similar biochemical remission rates in men with microprolactinomas and macroprolactinomas.

Paroxetine is a selective serotonin reuptake inhibitor (SSRI), with antidepressant and anxiolytic activity. In 6- to 24-week well designed trials, oral paroxetine 10 to 50 mg/day was significantly more effective than placebo, at least as effective as tricyclic antidepressants (TCAs) and as effective as other SSRIs and other antidepressants in the treatment of major depressive disorder. Relapse or recurrence over 1 year after the initial response was significantly lower with paroxetine 10 to 50 mg/day than with placebo and similar to that with imipramine 50 to 275 mg/day. The efficacy of paroxetine 10 to 40 mg/day was similar to that of TCAs and fluoxetine 20 to 60 mg/day in 6- to 12-week trials in patients aged > or =60 years with major depression. Paroxetine 10 to 40 mg/day improved depressive symptoms to an extent similar to that of TCAs in patients with comorbid illness, and was more effective than placebo in the treatment of dysthymia and minor depression. Paroxetine 20 to 60 mg/day was more effective than placebo after 8 to 12 weeks' treatment of obsessive-compulsive disorder (OCD), panic disorder, social anxiety disorder (social phobia), generalised anxiety disorder (GAD) and post-traumatic stress disorder (PTSD). Improvement was maintained or relapse was prevented for 24 weeks to 1 year in patients with OCD, panic disorder, social anxiety disorder or GAD. The efficacy of paroxetine was similar to that of other SSRIs in patients with OCD and panic disorder and similar to that of imipramine but greater than that of 2'chlordesmethyldiazepam in patients with GAD. Paroxetine is generally well tolerated in adults, elderly individuals and patients with comorbid illness, with a tolerability profile similar to that of other SSRIs. The most common adverse events with paroxetine were nausea, sexual dysfunction, somnolence, asthenia, headache, constipation, dizziness, sweating, tremor and decreased appetite. In conclusion, paroxetine, in common with other SSRIs, is generally better tolerated than TCAs and is a first-line treatment option for major depressive disorder, dysthymia or minor depression. Like other SSRIs, paroxetine is also an appropriate first-line therapy for OCD, panic disorder, social anxiety disorder, GAD and PTSD. Notably, paroxetine is the only SSRI currently approved for the treatment of social anxiety disorder and GAD, which makes it the only drug of its class indicated for all five anxiety disorders in addition to major depressive disorder. Thus, given the high degree of psychiatric comorbidity of depression and anxiety, paroxetine is an important first-line option for the treatment of major depressive disorder, OCD, panic disorder, social anxiety disorder, GAD and PTSD.

A critical evaluation of hormonal contraceptives is presented. The pills have been used for more than 100 million women all over the world. During the 25 years of their commercialization, there has been an improvement in their composition, today being considered almost perfect. The side effects can be summarized in 3 groups: endocrine-sexual such as vomiting, headaches, menstrual irregularity; systemic such as thromboembolism, sodium retention, hypertension; and general such as irritability and sexual dysfunction. The pills have some protective effects in the endometrium against cancer, and also against pelvic inflammations. They also can be used to treat uterine bleeding and endometriosis.

Of late, regional anesthesia has enjoyed unprecedented popularity; this increase in cases has brought a higher frequency of instances of neurological deficit and arachnoiditis that may appear as transient nerve root irritation, cauda equina, and conus medullaris syndromes, and later as radiculitis, clumped nerve roots, fibrosis, scarring dural sac deformities, pachymeningitis, pseudomeningocele, and syringomyelia, etc., all associated with arachnoiditis. Arachnoiditis may be caused by infections, myelograms (mostly from oil-based dyes), blood in the intrathecal space, neuroirritant, neurotoxic and/or neurolytic substances, surgical interventions in the spine, intrathecal corticosteroids, and trauma. Regarding regional anesthesia in the neuroaxis, arachnoiditis has resulted from epidural abscesses, traumatic punctures (blood), local anesthetics, detergents, antiseptics or other substances unintentionally injected into the spinal canal. Direct trauma to nerve roots or the spinal cord may be manifested as paraesthesia that has not been considered an injurious event; however, it usually implies dural penetration, as there are no nerve roots in the epidural space posteriorly. Sudden severe headache while or shortly after an epidural block using the loss of resistance to air approach usually suggests pneumocephalus from an intradural injection of air. Burning severe pain in the lower back and lower extremities, dysesthesia and numbness not following the usual dermatome distribution, along with bladder, bowel and/or sexual dysfunction, are the most common symptoms of direct trauma to the spinal cord. Such patients should be subjected to a neurological examination followed by an MRI of the effected area. Further spinal procedures are best avoided and the prompt administration of IV corticosteroids and NSAIDs need to be considered in the hope of preventing the inflammatory response from evolving into the proliferative phase of arachnoiditis.

Tricyclic antidepressants have been used to manage pain for several decades, and are superior treatments for some patients suffering from neuropathic pain. Unfortunately, older antidepressants have dose-limiting side effects that can lead to drug intolerance. The most common are anticholinergic side effects, although some patients experience sexual dysfunction. Cognitive impairment, sedation, and orthostatic hypotension also are relatively common. Taking an overdose of tricyclic antidepressants can be lethal in overdose. Several weeks of therapy may be required before antinociception occurs, but tricyclic antidepressants in optimal doses appear to be the most effective treatment for neuropathic pain; this is supported by systematic reviews comparing them with other agents. Newer medications such as atypical antidepressants and anticonvulsants may be overtaking older antidepressants, but they should not be overlooked as important options for the management of pain.

Premenstrual dysphoric disorder (PMDD) is considered a severe form of premenstrual syndrome. Symptoms of PMDD occur during the last week of the luteal phase of the menstrual cycle and usually abate at the onset of menses. About 3-8% of all menstruating women experience PMDD, which can lead to significant functional impairment. Several randomized, controlled trials have assessed the efficacy of selective serotonin reuptake inhibitors (SSRIs) in the treatment of PMDD. The SSRIs were found to significantly improve symptoms, particularly psychological or behavioral symptoms, during the luteal phase in women with PMDD. Also, SSRIs were found to improve the quality of life in women with PMDD. Headache, fatigue, insomnia, and anxiety were often reported as adverse effects. A decrease in libido or sexual dysfunction also was reported. In recent studies, intermittent SSRI therapy was found to be effective treatment for PMDD and allows a woman to take the drug for only 14 days each month. Intermittent SSRI therapy should be recommended before continuous daily dosing of SSRIs in the treatment of PMDD.

Three wharf workers were acutely exposed to toluene diisocyanate (TDI) during an accidental chemical spill. Toluene is neurotoxic as a solvent, while cyanates can cause nervous tissue injury or death by hypoxia. Chronic symptoms which occurred following the incident included headache, fatigue, concentration problems, irritability, depression, sleep disturbance, memory and sexual dysfunction. Compared with two months post-exposure, at 16 months post-exposure Full Scale IQ dropped an average of 23 points. Results from additional neuropsychological testing at 16 months post-exposure indicated severe deficits in all three subjects in memory, manual dexterity, visuomotor tracking, mental flexibility, ability to detect figure-ground relationships, and word fluency. Nerve conduction velocity testing indicated abnormal peripheral nervous system function in two of the three workers; however, its etiology is not certain. These results may be relevant to the neurotoxicity of methyl isocyanate exposure, such as occurred in Bhopal, India, where an increasing magnitude of depression, anxiety, fatigue, restlessness, and headaches 18 months post-exposure have been reported. In general, continuing decrement in mental function without concomitant environmental exposure should be considered in neuropsychological assessment of chemical toxicity.

Metoprolol has not yet been systematically studied in terms of quality of life and incidence of adverse drug reactions (ADRs). Metoprolol is metabolized by polymorphic CYP2D6, therefore poor CYP2D6 metabolizers may be at higher risk of ADRs. Therefore, it is to be proven whether genotyping is useful to guide initial dose selection. In the ongoing UNAMET study, nonrandomized out-patients start treatment with metoprolol for various disorders. With the use of standard questionnaires, the patients are prospectively evaluated for common ADRs (headache, dizziness, tiredness, sleep disturbances, dyspnea, cold extremities, sexual dysfunction) and quality of life. The questionnaires are filled out before and until 6 weeks after initiating therapy; blood pressure and heart rate are also measured. The acquired data are then related to the patients' metoprolol dose and plasma concentrations, as well as to their metabolic ratio of metoprolol/alpha-OH-metoprolol and CYP2D6 genotype.

Neuromodulation in one form or another has been studied for decades for various disease states. Although its mechanism of action remains un-explained, numerous clinical success stories suggest it is a therapy with efficacy and durability. Controlled studies have led to the approval of sacral neuromodulation for urinary urgency and frequency, urinary retention, and urinary urge incontinence. The future holds hopeful possibilities for the application of neuromodulation, namely in the areas of interstitial cystitis, in-tractable pain syndromes, fecal incontinence and constipation, spinal cord injury, and erectile dysfunction. Neuromodulators have also been used in nonurologic conditions, including chronic headaches and intractable chest pain. In adults and children, in the neurologically intact and neurologically impaired, neuromodulation has been shown to improve the quality of life of those suffering chronic disease states. Neuromodulation is changing the future of urology. Treatment of voiding dysfunction and likely other disorders, such as pelvic pain, sexual dysfunction, and bowel disorders, will no longer rely only on medications that are "OK" or destructive-reconstructive procedures that suffer from significant complications. Rather, by modulating the nerves, the urologists will treat these disorders in a minimally invasive fashion and neuromodulation will become the first-line therapy before any major surgery is undertaken.
