Thiele massage as a therapeutic option for women with chronic pelvic pain caused by tenderness of pelvic floor muscles

Aims and objectives Musculoskeletal system has been found to be involved in genesis and perpetuation of chronic pelvic pain (CPP) and has strong evidences that up to 80% of women with CPP present dysfunction of the musculoskeletal system. In this study, we report a series of women with CPP caused by tenderness of pelvic floor muscles successfully treated with Thiele massage. Methods Were included in this study six women with CPP caused by tenderness of the levator ani muscle that underwent transvaginal massage using the Thiele technique, over a period of 5 minutes repeated once a week for 4 weeks. After 1 month, the women returned for follow-up. Results The median tenderness score for the six women evaluated was 3 at the first evaluation and 0 after 1 month of follow-up (P < 0.01). The mean Visual Analogue Scale and McGill Pain Index scores were 8.1 and 34, respectively, at the first evaluation, and 1.5 and 16.6 at follow-up (P < 0.01). Conclusion Thiele massage appears to be very helpful for women with CPP caused by tenderness of the levator ani muscle. However, these results are preliminary and a larger number of women are necessary to obtain more conclusive results.

Diabetes and Vascular Disease: Basic Concepts of Nitric Oxide Physiology, Endothelial Dysfunction, Oxidative Stress and Therapeutic Possibilities

The vascular manifestations associated with diabetes mellitus (DM) result from the dysfunction of several vascular physiology components mainly involving the endothelium, vascular smooth muscle and platelets. It is also known that hyperglycemia-induced oxidative stress plays a role in the development of this dysfunction. This review considers the basic physiology of the endothelium, especially related to the synthesis and function of nitric oxide. We also discuss the pathophysiology of vascular disease associated with DM. This includes the role of hyperglycemia in the induction of oxidative stress and the role of advanced glycation end-products. We also consider therapeutic strategies.

Metalloproteinase inhibition protects against cardiomyocyte injury during experimental acute pulmonary thromboembolism

Objectives: Up-regulated matrix metalloproteinases may be involved in the development of cardiomyocyte injury and the degradation of troponin associated with acute pulmonary thromboembolism. We examined whether pretreatment with doxycycline (a nonspecific matrix metalloproteinase inhibitor) protects against cardiomyocyte injury associated with acute pulmonary thromboembolism. Design: Controlled animal study. Setting: University research laboratory. Subjects: Mongrel dogs. Interventions: Anesthetized animals received doxycycline (10 mg/kg intravenously) or saline and acute pulmonary thromboembolism was induced with autologous blood clots injected into the right atrium. Control animals received doxycycline (or saline). Measurements and Main Results: Hemodynamic measurements were performed, and acute pulmonary thromboembolism increased baseline mean pulmonary arterial pressure and pulmonary vascular resistance by approximately 160% and 362%, respectively (both p<.05), 120 mins after acute pulmonary thromboembolism. Pretreatment with doxycycline attenuated these increases (to 125% and 232%, respectively; both p<.05). Although acute pulmonary thromboembolism tended to increase the right ventricle maximum rate of isovolumic pressure development and the maximum rate of isovolumic pressure decay, doxycycline produced no effects on these parameters. Gelatin zymograms of right ventricle showed that acute pulmonary thromboembolism marginally increased matrix metalloproteinase-9 (but not matrix metalloproteinase-2) levels in the right ventricle. A fluorometric assay to assess net matrix metalloproteinase activities showed that acute pulmonary thromboembolism increased matrix metalloproteinase activities in the right ventricle by >100% (p<.05), and this finding was confirmed by in situ zymography of the right ventricle. Doxycycline attenuated acute pulmonary thromboembolism-induced increases in right ventricle matrix metalloproteinase activities. Acute pulmonary thromboembolism induced neutrophil accumulation in the right ventricle, as estimated by myeloperoxidase activity, and doxycycline blunted this effect (p<.05). Serum cardiac troponin I concentrations, which reflect cardiomyocyte injury, increased after acute pulmonary thromboembolism, and this increase was attenuated by pretreatment with doxycycline (p<.05). Conclusions: We found evidence supporting the idea that acute pulmonary thromboembolism is associated with increased matrix metalloproteinase activities in the right ventricle, which may lead to degradation of sarcomeric proteins, including cardiac troponin I. Inhibition of matrix metalloproteinases may be an effective therapeutic intervention in the management of acute pulmonary thromboembolism. (Crit Care Med 2011; 39: 349-356)

Pulmonary vascular remodeling: a target for therapeutic intervention in pulmonary hypertension

Pulmonary vascular remodeling is an important pathological feature of pulmonary hypertension, leading to increased pulmonary vascular resistance and reduced compliance. It involves thickening of all three layers of the blood vessel wall (due to hypertrophy and/or hyperplasia of the predominant cell type within each layer), as well as extracellular matrix deposition. Neomuscularisation of non-muscular arteries and formation of plexiform and neointimal lesions also occur. Stimuli responsible for remodeling involve transmural pressure, stretch, shear stress, hypoxia, various mediators [angiotensin II, endothelin (ET)-1, 5-hydroxytryptamine, growth factors, and inflammatory cytokines], increased serine elastase activity, and tenascin-C. In addition, there are reductions in the endothelium-derived antimitogenic substances, nitric oxide, and prostacyclin. Intracellular signalling mechanisms involved in pulmonary vascular remodeling include elevations in intracellular Ca2+ and activation of the phosphatidylinositol pathway, protein kinase C, and mitogen-activated protein kinase. In animal models of pulmonary hypertension, various drugs have been shown to attenuate pulmonary vascular remodeling. These include angiotensin-converting enzyme inhibitors, angiotensin receptor antagonists, ET receptor antagonists, ET-converting enzyme inhibitors, nitric oxide, phosphodiesterase 5 inhibitors, prostacyclin, Ca2+-channel antagonists, heparin, and serine elastase inhibitors. Inhibition of remodeling is generally accompanied by reductions in pulmonary artery pressure. The efficacy of some of the drugs varies, depending on the animal model of the disease. In view of the complexity of the remodeling process and the diverse aetiology of pulmonary hypertension in humans, it is to be anticipated that successful anti-remodeling therapy in the clinic will require a range of different drug options.

Rehabilitation outcomes following percutaneous coronary interventions (PCI)

This prospective study evaluated the effect of an individualized, comprehensive, home-based cardiac rehabilitation program combining exercise training with risk factor modification and psychosocial counseling on risk factors, psychological wellbeing, functional capacity, and work resumption in 99 post-percutaneous coronary interventions (PCI) patients randomized to control (standard care plus telephone follow-up, n = 49) or intervention (individualized, comprehensive, home-based cardiac rehabilitation, n = 50) groups. Data were collected at time 1 (T-1) during hospital admission, time 2 (T-2) approximately 2 months post-PCI, and time 3 (T-3) approximately 12 months post-PCI. Results suggest that the allocation to an individualized, comprehensive, home-based cardiac rehabilitation program provided more advantageous outcomes. At both follow-ups, the intervention group showed within-group improvement in serum cholesterol levels (P < 0.02; P < 0.01) and exercise participation (P < 0.001; P < 0.001) with differences in exercise participation favoring the intervention group (P < 0.01) at T-2 Repeated measures ANOVA showed significant improvements over time in body mass index (BMI) (P < 0.01), psychological well-being (P < 0.001), and functional capacity (P < 0.001) for both groups. More patients in the intervention group had returned to work at T-2 (P < 0.001) and did so more quickly (P < 0.01). These findings suggest that an individualized, comprehensive, home-based cardiac rehabilitation program improves risk factor profiles and work resumption patterns for patients following PCI.

Drug use evaluation of ipratropium bromide at two tertiary referral hospitals in Brisbane.

Objective: To assess the appropriateness of ipratropium bromide prescribing in two tertiary referral hospitals. Method: Criteria for optimal use were developed based on current literature and modified after consultation with respiratory physicians and clinical pharmacists. A prospective review of prescribing was performed over a 2-month period to assess conformity to these criteria. Results: Information was collected from 84 patients; 5% were receiving inhalers and 96% nebuliser therapy (one patient used both). 77% of patients (n = 65) had a principal diagnosis of chronic obstructive pulmonary disease, 14% (n = 12) asthma and 8% (n = 7) had neither diagnosis. 75% of patients were using ipratropium outside the guidelines. The major areas where the guidelines were not met were a lack of therapeutic justification, use of inappropriate doses, and use of an inappropriate delivery device. Feedback and educational interventions were designed and delivered based on the data obtained. Conclusions: There was widespread use of ipratropium outside the developed guidelines. Interventions in specific areas could lead to significant improvements in the use of this high cost drug
