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.

Importance of Pelvic Muscle Tenderness Evaluation in Women with Chronic Pelvic Pain

Objective. To determine the prevalence of pelvic muscle tenderness in women with chronic pelvic pain (CPP) and to assess the importance of evaluating muscle tenderness in such women. Design. Observational study of 48 healthy female volunteers and 108 women with CPP, who were clinically evaluated for pelvic muscle tenderness by two researchers blinded to all clinical data. Results. The frequency of clinically detected pelvic muscle tenderness was significantly higher in women with CPP than in healthy volunteers (58.3% vs 4.2%, P < 0.001). Among women with CPP, those with pelvic muscle tenderness had higher Beck Depression Index scores (22 [6-42] vs 13 [3-39], P = 0.02) and higher rates of dyspareunia (63.5% [40/63] vs 28.9% [13/45], P < 0.004) and constipation (46.0% [29/63] vs 26.7% [12/45], P = 0.05) than those without pelvic muscle tenderness. Conclusion. Tenderness of pelvic muscles was highly prevalent among women with CPP and was associated with higher BDI scores and higher rates of dyspareunia and constipation. Determination of pelvic muscle tenderness may help in identifying women who require more intense treatment for CPP.

Impact of Surgical Staging in Locally Advanced Cervical Cancer and Subsequent Chemotherapy

Background: Surgical staging (SS) is the gold standard for determination of the true extent of a patient`s disease and is an important prognostic factor in cervical cancer. We investigated whether lymph node dissection (LND) prior to chemotherapy (CT) followed by radical surgery (RS) could modified overall (OS) and disease-free survival (DFS). Methods: We performed a cohort analysis of 98 patients with cervical carcinoma. The experimental group consisted of 36 patients who underwent SS followed by neoadjuvant chemotherapy, and then by RS (objective response) or chemo-radiation therapy (with or without subsequent surgery when not possible). The control group consisted of 62 similarly treated patients without pretreatment SS. The value of this procedure as a diagnostic tool in defining the extent of disease was evaluated. Furthermore, LND/CT-associated treatment complications and the impacts on OS and DFS were also evaluated. Results: Fourteen (38.9%) patients had pelvic LN metastases and three (8.3%) patients had pelvic and para-aortic LN metastases. The 39-month OS and DFS rates for the current study were 90.6% for the staged group and 52% for non-staged treatment (P < 0.001). Conclusion: SS in cervical cancer is a feasible and safe pretreatment procedure, and when associated with CT, it improves OS and DFS. J. Surg. Oncol. 2009;100:505-510. (C) 2009 Wiley-Liss, Inc.

High levels of anxiety and depression have a negative effect on quality of life of women with chronic pelvic pain

Chronic pelvic pain (CPP) is a common and complex disease whose cause is often clinically inexplicable, with consequent difficulty in diagnosis and treatment. Patients with CPP have high levels of anxiety and depression, with a consequent impairment of their quality of life. The objective of this study was to determine the prevalence of anxiety and depression and their impact on the quality of life of women with CPP. A cross-sectional controlled study was conducted on 52 patients with CPP and 54 women without pain. Depression and anxiety were evaluated by the Hospital Anxiety and Depression Scale, and quality of life was evaluated by the World Health Organization Quality of life Whoqol-bref questionnaire. Data were analysed statistically by the Mann-Whitney U-test, the Fisher exact test, chi-square test and Spearman correlation test. The prevalence of anxiety was 73% and 37% in the CPP and control groups, respectively, and the prevalence of depression was 40% and 30% respectively. Significant differences between groups were observed in the physical, psychological and social domains. Patients with higher anxiety and depression scores present lower quality of life scores. The fact that DPC is a syndromic complex, many patients enter a chronic cycle of search for improvement of medical symptoms. The constant presence of pain may be responsible for affective changes in dynamics, family, social and sexual. Initially the person is facing the loss of a healthy body and active, to a state of dependence and limitations. In this study, patients with higher scores of anxiety and depression scores had lower quality of life and patients with lower scores of anxiety and depression had scores of quality of life. These results show that perhaps the depression and anxiety may be related to the negative impact on quality of life of these patients. In view of this association, we emphasise the importance of a specific approach to the treatment of anxiety and depression together with clinical treatment to improve the quality of life of these patients.

Increased Capsaicin Receptor TRPV1 in the Peritoneum of Women With Chronic Pelvic Pain

Objective: To investigate the expression of capsaicin receptor [transient receptor potential vanilloid type-1 (TRPV1)] in the peritoneum of women with chronic pelvic pain (CPP). Methods: A case-control study was conducted on 25 women with CPP and 10 controls. Samples of the rectouterine excavation (2 cm 2) were obtained by laparoscopy, fixed in 4% formaldehyde, and underwent immunohistochemistry analysis using rabbit anti-TRPV1 (1:400) polyclonal antibodies and anti-protein gene product 9.5 (PGP 9.5) (1:2000) as a neuronal marker. Ten sequential images of high magnification fields ( x 40) were captured from each slide and the area identified with the antibody was calculated with Kontron V2.0 software. Results: Immunoreactivity to TRPV1 was sparsely detected in the nervous tissue and epithelium of endometriotic lesions. The percent area of immunoreactivity for TRPV1 [expressed as median (range)] was greater in specimens from women with CPP, 1.02% (0.54 to 2.93), than from women without the disease, 0.14% (0.07 to 1.12) (P<0.0001). This greater expression was not secondary to an increase in neuronal fibers because there was also a significant difference in the percent area TRPV1:PGP 9.5 ratio between women with CPP, 1.18 (0.26 to 4.63), and controls, 0.15 (0.06 to 0.95) (P = 0.0003). Discussion: TRPV1 may play an important role in the maintenance and perpetuation of symptoms in women with CPP. In view of the immunoreactivity detected for TRPV1, the endometriotic lesion may have the ability to interfere with nociception or with the inflammatory peritoneal environment in women with CPP. Further Studies are needed to elucidate the participation of TRPV1 in CPP and its association with endometriosis.

Primary adenocarcinoma of the fallopian tube as an incidental finding during surgery in a postmenopausal patient with unspecific pelvic pain

Primary fallopian tube carcinoma (PFTC) is a rare gynecologic neoplasm and is usually diagnosed late and presents classically with a,characteristic group of symptoms. We describe a case of a 76-year-old woman who underwent TVS requested by the family physician due to unspecific pelvic pain. An adnexal mass was found with morphology associated with high levels of CA125 suggestive of a malignant tumor. During laparotomy, a mass located in the left tube was found. Histopathology confirmed PFTC. Total hysterectomy, salpingo-oophorectomy and adjuvant chemotherapy with carboplatin/paclitaxel were performed. The patient has not yet presented any signs of recurrence.

TRPV1 Expression on Peritoneal Endometriosis Foci is Associated With Chronic Pelvic Pain

Objective: To investigate the expression of capsaicin receptor (transient receptor potential vanilloid type 1 [TRPV1]) in the peritoneal endometriosis foci of women with and without chronic pelvic pain (CPP). Methods: A case-control study was conducted on 49 women with endometriosis who underwent laparoscopy, 28 of whom had CPP and 21 without CPP. Samples from peritoneum of the rectouterine excavation (2 cm(2)) were obtained by laparoscopy, fixed in 4% formaldehyde, and underwent immunohistochemistry analysis using rabbit anti-TRPV1 (1:400) polyclonal antibody. Results: Image analysis revealed that the immunoreactivity for TRPV1 was more frequent in specimens (endometriosis foci) from women with CPP (n = 15 of 28, 53.6%), compared to samples from the endometriosis foci of women without CPP (n = 6 of 21, 28.6%; P = .04). There was no correlation with duration, intensity of pain, or stage of the disease (endometriosis). Discussion: The present study shows that TRPV1 expression in peritoneal endometriosis foci is related to CPP in women. However, this association is not related to the endometriosis stage. In view of the immunoreactivity for TRPV1 observed here, we believe that some endometriotic lesions may provide a scenario for TRPV1 to be tonically active and this activity may contribute to the underlying pathology of CPP.

Comparison of pelvic floor muscle strength between women undergoing vaginal delivery, cesarean section, and nulliparae using a perineometer and digital palpation

Objectives. To compare pelvic floor muscle (PFM) strength between women undergoing vaginal delivery, cesarean section, and nulliparae, investigating the factors associated with PFM strength, and observing the correlation between vaginal digital palpation and use of a perineometer. Methods. A cross-sectional study was conducted, including 31 women following vaginal delivery, 30 women following cesarean section, and 30 nulliparous women. PFM strength was measured by vaginal digital palpation and use of a perineometer. Multiple linear regression analysis with adjustment for covariables was used to compare the mean PFM strength and identify its associated factors. Results. The mean PFM strength of women undergoing vaginal delivery and cesarean section was 25.6 +/- 14.5 cmH(2)O and 39.6 +/- 22.0 cmH(2)O (p < 0.01, adjusted for covariables), respectively. A correlation was observed between measurements of PFM strength obtained by vaginal digital palpation and use of a perineometer (tau = 0.82; p < 0.01). The non-white race/ethnicity was negatively associated with PFM strength (coefficient: -10.2424; p = 0.02). Conclusions. A lower PFM strength was observed in women with a history of vaginal delivery compared to those undergoing cesarean section. Non-white race/ethnicity negatively affected PFM strength. Our data suggest that vaginal digital palpation may be used in clinical practice because of its expressive correlation with use of a perineometer.

Pulp Vitality in Patients with Intraoral and Oropharyngeal Malignant Tumors Undergoing Radiation Therapy Assessed by Pulse Oximetry

Introduction: The aim of this study was to evaluate pulp oxygenation levels (%SpO(2)) in patients with malignant intraoral and oropharyngeal tumors treated by radiotherapy (RT). Methods: Pulp oxygenation levels were measured by pulse oximetry. Twenty patients were selected, and two teeth of each participant (n = 40) were analyzed, regardless of the quadrant and the area irradiated, at four different time points: TP1, before RI; TP2, at the beginning of RI with radiation doses between 30 and 35 Gy; TP3, at the end of RI with radiation dose! between 60 and 70 Gy; and TP4, 4 to 5 months after the beginning of cancer treatment. Results: Mean %SpO(2) at the different time points were 93% (TP1), 83% (TP2), 77% (TP3), and 85% (TP4). The Student`s t test showed statistically significant differences between TP1 and TP2 (P < .01), TP3 (P <.01), and TP4 (P <.01). TP3 was also statistically significantly different when compared with TP2 (P <.01) and TP4 (P <.01). No statistically significant difference could be observed between TP2 and TP4. Conclusion`s: Because the mean %SpO(2) before RI was greater than during and after therapy and values obtained 4 to 5 months after the beginning of RI were close to the initiation of RI, pulp tissue may be able to regain normal blood flow after RT. If the changes in the microcirculation of the dental pulp were indeed transitory, preventive endodontic treatment or extraction in patients who are currently undergoing or recently received RI and who show negative signs of pulp sensitivity may rot be necessary for pulpal reasons.

gamma-Radiation induces apoptosis via sarcoplasmatic reticulum in guinea pig ileum smooth muscle cells

We investigated the effects of gamma-radiation on cells isolated from the longitudinal smooth muscle layer of the guinea pig ileum, a relatively radioresistant tissue. Single doses (up to 50 Gy) reduced the amount of sarcoplasmatic reticulum and condensed the myofibrils, as shown by electron microscopy 3 days post-irradiation. After that, contractility of smooth muscle strips was reduced. Ca(2+) handling was altered after irradiation, as shown in fura-2 loaded cells, with elevated basal intracellular Ca(2+), reduced amount of intrareticular Ca(2+), and reduced capacitive Ca(2+) entry. Radiation also induced apoptosis, judged from flow cytometry of cells loaded with proprium iodide. Electron microscopy showed that radiation caused condensation of chromatin in dense masses around the nuclear envelope, the presence of apoptotic bodies, fragmentation of the nucleus, detachment of cells from their neighbors, and reductions in cell volume. Radiation also caused activation of caspase 12. Apoptosis was reduced by the administration of the caspase inhibitor Z-Val-Ala-Asp-fluoromethyl-ketone methyl ester (Z-VAD-FIVIK) during the 3 day period after irradiation, and by the chelator of intracellular Ca(2+), 1,2-bis(o-aminophenoxy)ethane-N,N,N`,N`-tetraacetic acid (BAPTA), from 1 h before until 2 h after irradiation. BAPTA also reduced the effects of radiation on contractility, basal intracellular Ca(2+), amount of intrareticular Ca(2+), capacitative Ca(2+) entry, and apoptosis. In conclusion, the effects of gamma radiation on contractility, Ca(2+) handling, and apoptosis appear due to a toxic action of intracellular Ca(2+). Ca(2+)-induced damage to the sarcoplasmatic reticulum seems a key event in impaired Ca(2+) handling and apoptosis induced by gamma-radiation. (c) 2008 Elsevier B.V. All rights reserved.

X-ray fluorescence with synchrotron radiation to elemental analysis of lead and calcium content of primary teeth

Primary teeth were analyzed by micro-SRXRF. The aim of this study was to determine the elemental distribution of lead and calcium in different regions of primary incisor of children living in a notoriously contaminated area (Santo Amaro da Purificacao, Bahia State, Brazil). The measurements were performed in standard geometry of 45 incidence, exciting with a white beam and using a conventional system collimation (orthogonal slits) in the XRF beamline at the Synchrotron Light National Laboratory (Campinas, Brazil).

Thermal characterization of copolymers obtained by radiation grafting of styrene onto poly(tetrafluoroethyleneperfluoropropylvinylether) substrates: thermal decomposition, melting behavior and low-temperature transitions

Differential scanning calorimetric (DSC) and thermogravimetric analysis (TGA) have been used to study the thermal decomposition, the melting behavior and low-temperature transitions of copolymers obtained by radiation-induced grafting of styrene onto poly (tetrafluoroethylene- perfluoropropylvinylether) (PFA) substrates. PFA with different contents of perfluoropropylvinylether (PPVE) as a comonomer have been investigated. A two step degradation pattern was observed from TGA thermograms of all the grafted copolymers, which was attributed to degradation of PSTY followed by the degradation of the PFA backbone at higher temperature. One broad melting peak can be identified for all copolymers, which has two components in the samples with higher PPVE content. The melting peak, crystal-crystal transition and the degree of crystallinity of the grafted copolymers increases with radiation grafting up to 50 kGy, followed by a decrease at higher doses. No such decrease was observed in the ungrafted PFA samples after irradiation. This indicated that the changes in the heats of transitions and crystallinity at low doses are due to the radiation effects on the microstructure of PFA (chain scission), whereas at higher doses the grafted PSTY is the driving force behind these changes.
