Neurostimulation methods for control of chronic neuropathic pain have recently gained in popularity. The reasons for this are multifactorial. As opposed to nerve ablation, these methods are minimally invasive and reversible. The improvements in hardware design simplified implantation techniques and prolonged equipment longevity. Stimulation trials have become less invasive, allowing patients to test its effects before final implantation. Finally, the scientific evidence has shown good outcomes of neurostimulation methods for chronic neuropathic pain control. Recent research efforts have revealed new potential mechanisms of action of neurostimulation. Whereas its action was widely explained by gate control theory in the past, it seems that neuromodulation acts also by modulation of neurotransmitters in the central nervous system. Three neurostimulation methods are currently used in clinical practice: spinal cord stimulation (SCS), peripheral nerve stimulation (PNS), and deep brain stimulation (DBS). The SCS and PNS are excellent treatment choices for certain forms of neuropathic pain. The new indications for SCS are end-stage peripheral vascular disease and ischemic heart disease, whereas PNS is used for the treatment of occipital neuralgia and chronic pelvic pain. DBS is reserved for carefully selected patients in whom the other treatment modalities have failed. In a minority of patients the "tolerance" to neurostimulation develops after long-term use. Further research is needed to establish better outcome predictors to neurostimulation and possibly improve patient selection criteria.

Spinal cord stimulation (SCS) is a reversible treatment for chronic pain that is gaining favor as a first-line therapy for many disease states. Because there are no addictive issues and no side effects systemically, the treatment is moving up the treatment continuum ladder. First used clinically in 1967, the procedure was used exclusively for failed back surgery syndrome. Over the past 30 years selection criteria, psychologic screening, and technology have improved. These advances have broadened the treatment options for many patients in pain. This review focuses on the selection, indications, techniques, new advances, complications, and outcomes involved with SCS. A review is provided for the treatment of radiculitis, failed back surgery syndrome, complex regional pain syndrome, peripheral neuropathies, pelvic pain, occipital neuralgia, angina, ischemic extremity pain, and spasticity. Technologic advances such as multi-lead and multi-electrode arrays are also discussed in regard to the impact these developments have on the clinical application of the therapy.

Primary dysmenorrhea is a syndrome characterized by painful uterine contractility caused by a hypersecretion of endometrial prostaglandins; non-steroidal anti-inflammatory drugs are the first choice for its treatment. However, in vivo and in vitro studies have demonstrated that myometrial cells are also targets of the relaxant effects of nitric oxide (NO). The aim of the present study was to determine the efficacy of glyceryl trinitrate (GTN), an NO donor, in the resolution of primary dysmenorrhea in comparison with diclofenac (DCF). A total of 24 patients with the diagnosis of severe primary dysmenorrhea were studied during two consecutive menstrual cycles. In an open, cross-over, controlled design, patients were randomized to receive either DCF per os or GTN patches the first days of menses, when menstrual cramps became unendurable. In the subsequent cycle the other treatment was used. Patients received up to 3 doses/day of 50 mg DCF or 2.5 mg/24 h transdermal GTN for the first 3 days of the cycle, according to their needs. The participants recorded menstrual symptoms and possible side-effects at different times (0, 30, 60, 120 minutes) after the first dose of medication on the first day of the cycle, with both drugs. The difference in pain intensity score (DPI) was the main outcome variable. Both treatments significantly reduced DPI by the 30th minute (GTN, -12.8 +/- 17.9; DCF, -18.9 +/- 16.6). However, DCF continued to be effective in reducing pelvic pain for two hours, whereas GTN scores remained more or less stable after 30 min and significantly higher than those for DFC (after one hour: GTN, -12.8 +/- 17.9; DFC, -18.9 +/- 16.6 and after two hours: GTN, -23.7 +/- 20.5; DFC, -59.7 +/- 17.9, p = 0.0001). Low back pain was also relieved by both drugs. Headache was significantly increased by GTN but not by DCF. Eight patients stopped using GTN because headache--attributed to its use--became intolerable. These findings indicate that GTN has a reduced efficacy and tolerability by comparison with DCF in the treatment of primary dysmenorrhea.

Violence against women has recently drawn attention in the medical community as a leading cause of preventable morbidity and mortality. Specific algorithms designed to identify women at risk can be applied to create an opportunity for screening, diagnosis and treatment during medical care initiated for common conditions. This study investigated the incidence and history of battering among women seeking general medical care, and looked for potential risk factors and associations with presenting symptoms. We used a self-administered, anonymous survey to question 1780 adult female outpatients visiting a tertiary care internal medicine teaching hospital in Mexico City. We calculated current abuse (physical and/or sexual abuse by a partner within the past year), abuse during pregnancy, childhood abuse, and lifetime abuse. We found levels of violence against women in Mexico comparable to those reported from other countries. 152 women (9%) reported current physical and/or sexual abuse. An identical number also reported abuse during pregnancy. Lifetime prevalence was 41%. Women currently or previously abused reported more physical symptoms in the last six months than did non-abused participants. Pelvic pain, depression, headache and substance abuse were frequent among abused women. Currently abused women also scored higher (p<0.01) on indicators of depression. Current abuse correlated strongly with a childhood history of physical and/or sexual abuse, with low educational level of the victim, with substance abuse by the partner or by the woman herself, and with higher parity.

Preliminary results of side effects are reported by 66 physicians of the M.F.P.F. (Mouvement Francais de Planning Familial) on 2026 women taking Stediril, 610 taking Aconcept, and 824 taking Ov 28 for at least 6 months (less for dropouts) since 1969. There were no pregnancies or severe complications except 1 case of jaundice and 2 of thrombosed hemorrhoids. Blood pressure was unchanged in 60-70% of cases, and the graph of these changes, except for a slight increase at "up to 10 mm Hg," was a symmetrical bell curve. Stediril and Ov 28 had identical effects on blood pressure, but the curve for Aconcept was flatter. Weight gain of 1 kg or more was reported in 37% of Stediril users and 42% of Ov 28 users (p less than .05). Other side effects showing significant differences between products were: nausea greater with Ov 28, depression greater with Aconcept, metrorragia greater with Stediril, pelvic pain less with Stediril, headaches less with Ov 28, amenorrhea less with Stediril. This absence of serious side effects was considered the most significant French statisitc published to date on oral contraceptives.

Health workers in Malaysia randomly assigned either a low-dose triphasic or a low-dose monophasic oral contraceptive (Triquilar and Marvelon, respectively) to 198 women to examine discontinuation rates and reasons for discontinuation. 15.3% of Triquilar women and 9.1% of Marvelon women forgot to take 1 pill at some time during the study while 6.1% and 3% forgot to take at least 3 consecutive pills. There were more complaints and/or complications among Triquilar women than among Marvelon women. The most serious complication was severe headaches (only 1 woman from each group). 2 women in the Marvelon group complained of either generalized itchiness or digestion impairment. Complaints of women in the Triquilar group included localized and generalized itchiness, weight gain, digestion impairment, dryness of vagina, and numbness of extremities. Women in the Triquilar group were more likely to have menstrual complaints than those in the Marvelon group (14.3% vs. 9.1%). The leading menstrual complaint in both groups was spotting (6.1% vs. 4%). No Marvelon women reported menorrhagia, scanty menses, or intermenstrual pelvic pain or discomfort while at least 1 woman did from the Triquilar group. The percentage of women with changes in complaints since admission were the same for both groups. Total discontinuation rates which included lost to follow ups were 46.9% and 40%, respectively. The most common reason for discontinuation for both groups was desired method change (11.2% Triquilar and 14.1% Marvelon). Method unrelated reasons (unable to return to clinic, moving/travel, and not interested in the study) were the next most common reason for discontinuation. 3 women conceived while taking Triquilar. These pregnancies were attributed to method failure, perhaps due to incomplete pituitary suppression. There were no accidental pregnancies in the Marvelon group.

Primary dysmenorrhoea is the most frequent gynaecological condition, with a prevalence of 40 - 90% in women within the reproductive age. It is characterised by cyclic pelvic pain related to menstrual period, vomiting and headache. As prostaglandins and leukotrienes appear to be a major causative factor in this condition, NSAIDs are the first choice for treatment. Acetaminophen is an over-the-counter analgesic/antipyretic agent widely used in primary dysmenorrhoea as monotherapy or in combination. It has a weak inhibitory action on peripheral prostaglandin synthesis. Acetaminophen displays good gastrointestinal tolerance without any effect on haemostasis. Its combination with pamabrom, a mild diuretic agent, (Women s Tylenol Menstrual Relief Caplets, Midol Teen) was approved by the FDA for use in this indication. Nevertheless, the available information concerning the efficacy of acetaminophen in primary dysmenorrhoea is limited and not conclusive with respect to other NSAIDs or even placebo. The clinical evidence regarding the association with pamabrom is even more scarce. Well-designed, randomised, controlled trials are required to demonstrate the efficacy of the combination of acetaminophen plus pamabrom in the treatment of primary dysmenorrhoea.

Treatment of pain of urogenital origin, chronic pelvic pain syndrome, can be frustrating for patients and physicians. The usual approaches do not always produce the desired results. Visceral pain from pelvic organs and myofascial pain from muscle trigger points share common characteristics. Referred pain from myofascial trigger points can mimic visceral pain syndromes and visceral pain syndromes can induce trigger point development and myofascial pain and dysfunction. The referred pain syndrome can long outlast the initial event, making diagnosis difficult.

Chronic pelvic pain is a potentially devastating condition that affects many women with severe consequences. A multifaceted condition, chronic pelvic pain enjoys a diverse etiology, a myriad of treatments, and a correspondingly irregular response to therapy. The condition can be associated with severe physical dysfunction in relation to voiding, defecation, and sexual function. Although emphasis has been placed on surgical approaches to therapy, there is increasing interest in alternative therapies, particularly using the principles of the treatment of myofascial dysfunction.

Although menopause is a normal developmental milestone through which all women pass, the transition has been long associated with chronic pain conditions that may be more accurately viewed as secondary to aging. Clinicians need to understand management of pain problems women may experience. This article examines pain syndromes including headache, back pain, osteoarthritis, pelvic pain, vulvo-vaginal pain, and burning mouth syndrome.
