Vaginal cuff dehiscence after vaginal cuff brachytherapy for uterine cancer. A case report  

PubMed Central

Vaginal cuff dehiscence is a rare, but potentially serious complication after total hysterectomy. We report a case of vaginal cuff dehiscence after vaginal cuff brachytherapy. A 62 year old female underwent a robotic-assisted laparoscopic hysterectomy with bilateral salpingo-oophorectomy, and was found to have International Federation of Gynecology and Obstetrics (FIGO) 2009 stage IB endometrioid adenocarcinoma of the uterus. The patient was referred for adjuvant vaginal cuff brachytherapy. During the radiation treatment simulation, a computerized tomography (CT) of the pelvis showed abnormal position of the vaginal cylinder. She was found to have vaginal cuff dehiscence that required immediate surgical repair. Vaginal cuff dehiscence triggered by vaginal cuff brachytherapy is very rare with only one case report in the literature.

Optimisation techniques in vaginal cuff brachytherapy.  

PubMed

The aim of this study was to explore whether an in-house dosimetry protocol and optimisation method are able to produce a homogeneous dose distribution in the target volume, and how often optimisation is required in vaginal cuff brachytherapy. Treatment planning was carried out for 109 fractions in 33 patients who underwent high dose rate iridium-192 (Ir(192)) brachytherapy using Fletcher ovoids. Dose prescription and normalisation were performed to catheter-oriented lateral dose points (dps) within a range of 90-110% of the prescribed dose. The in-house vaginal apex point (Vk), alternative vaginal apex point (Vk'), International Commission on Radiation Units and Measurements (ICRU) rectal point (Rg) and bladder point (Bl) doses were calculated. Time-position optimisations were made considering dps, Vk and Rg doses. Keeping the Vk dose higher than 95% and the Rg dose less than 85% of the prescribed dose was intended. Target dose homogeneity, optimisation frequency and the relationship between prescribed dose, Vk, Vk', Rg and ovoid diameter were investigated. The mean target dose was 99+/-7.4% of the prescription dose. Optimisation was required in 92 out of 109 (83%) fractions. Ovoid diameter had a significant effect on Rg (p = 0.002), Vk (p = 0.018), Vk' (p = 0.034), minimum dps (p = 0.021) and maximum dps (p<0.001). Rg, Vk and Vk' doses with 2.5 cm diameter ovoids were significantly higher than with 2 cm and 1.5 cm ovoids. Catheter-oriented dose point normalisation provided a homogeneous dose distribution with a 99+/-7.4% mean dose within the target volume, requiring time-position optimisation. PMID:19470571

Vaginal cuff dehiscence after intracavitary brachytherapy for endometrial cancer  

PubMed Central

We describe 2 unusual cases of vaginal dehiscence after intracavitary brachytherapy performed following robotic laparoscopic hysterectomy (RLH) along with their management. This unusual complication, which may be more common because of the robotic procedures, can be prevented by careful examination and possible delay of the onset of brachytherapy, if indicated. Our report reviews techniques of avoiding this complication and suggests that these complications should be discussed with the patients.

Magnitude of Interfractional Vaginal Cuff Movement: Implications for External Irradiation  

SciTech Connect

Purpose: To quantify the extent of interfractional vaginal cuff movement in patients receiving postoperative irradiation for cervical or endometrial cancer in the absence of bowel/bladder instruction. Methods and Materials: Eleven consecutive patients with cervical or endometrial cancer underwent placement of three gold seed fiducial markers in the vaginal cuff apex as part of standard of care before simulation. Patients subsequently underwent external irradiation and brachytherapy treatment based on institutional guidelines. Daily megavoltage CT imaging was performed during each external radiation treatment fraction. The daily positions of the vaginal apex fiducial markers were subsequently compared with the original position of the fiducial markers on the simulation CT. Composite dose-volume histograms were also created by summing daily target positions. Results: The average ({+-} standard deviation) vaginal cuff movement throughout daily pelvic external radiotherapy when referenced to the simulation position was 16.2 {+-} 8.3 mm. The maximum vaginal cuff movement for any patient during treatment was 34.5 mm. In the axial plane the mean vaginal cuff movement was 12.9 {+-} 6.7 mm. The maximum vaginal cuff axial movement was 30.7 mm. In the craniocaudal axis the mean movement was 10.3 {+-} 7.6 mm, with a maximum movement of 27.0 mm. Probability of cuff excursion outside of the clinical target volume steadily dropped as margin size increased (53%, 26%, 4.2%, and 1.4% for 1.0, 1.5, 2.0, and 2.5 cm, respectively.) However, rectal and bladder doses steadily increased with larger margin sizes. Conclusions: The magnitude of vaginal cuff movement is highly patient specific and can impact target coverage in patients without bowel/bladder instructions at simulation. The use of vaginal cuff fiducials can help identify patients at risk for target volume excursion.

Vaginal cuff dehiscence with adnexal mass evisceration after abdominal hysterectomy  

PubMed Central

INTRODUCTION More commonly, a vaginal cuff dehiscence is a complication of robotic or laparoscopic hysterectomy while dehiscence is less commonly observed following total abdominal or vaginal hysterectomies. PRESENTATION OF CASE Three years after an uncomplicated total abdominal hysterectomy for fibroid uterus, a 50 year old female with a known, large adnexal mass presented with vaginal cuff dehiscence and prolapse of the adnexal mass through the vaginal cuff. DISCUSSION We discuss surgical risk factors including route of hysterectomy, method of colpotomy and vaginal cuff closure as contributing factors for vaginal cuff dehiscence in our patient. CONCLUSION Any large pelvic mass that may potentially exert pressure necrosis on the vaginal cuff, even remote from hysterectomy may result a vaginal cuff dehiscence. Emergent surgical intervention is warranted.

Effects of Electrosurgery and Vaginal Closure Technique on Postoperative Vaginal Cuff Dehiscence  

PubMed Central

Background and Objectives: The aim of our study is to evaluate the role of electrosurgery and vaginal closure technique in the development of postoperative vaginal cuff dehiscence. Methods: From prospective surgical databases, we identified 463 patients who underwent total laparoscopic hysterectomy (TLH) for benign disease and 147 patients who underwent laparoscopic-assisted vaginal hysterectomy (LAVH) for cancer. All TLHs and LAVHs were performed entirely by use of electrosurgery, including colpotomy. Colpotomy in the TLH group was performed with Harmonic Ace Curved Shears (Ethicon Endo-Surgery, Cincinnati, OH, USA), and in the LAVH group, it was performed with a monopolar electrosurgical pencil. The main surgical difference was vaginal cuff closure—laparoscopically in the TLH group and vaginally in the LAVH group. Results: Although patients in the LAVH group were at increased risk for poor healing (significantly older, higher body mass index, more medical comorbidities, higher blood loss, and longer operative time), there were no vaginal cuff dehiscences in the LAVH group compared with 17 vaginal cuff dehiscences (4%) in the TLH group (P = .02). Conclusion: It does not appear that the increased vaginal cuff dehiscence rate associated with TLH is due to electrosurgery; rather, it is due to the vaginal closure technique.

Two cases of post-coital vaginal cuff dehiscence with small bowel evisceration after robotic-assisted laparoscopic hysterectomy  

PubMed Central

INTRODUCTION Vaginal cuff dehiscence following robotic surgery is uncommon. Published reports of vaginal cuff dehiscence following robotic surgery are increasing, but the true incidence is unknown. PRESENTATION OF CASE Case 1. A 45 year old female had sexual intercourse and presented with a vaginal cuff dehiscence complicated by small bowel evisceration 4 months after RA-TLH. Case 2. A 44 year old female had sexual intercourse and presented with a vaginal cuff dehiscence with small bowel evisceration 6 weeks after RA-TLH. DISCUSSION We discuss the rate of vaginal cuff dehiscence by mode of hysterectomy, surgical and non-surgical risk factors that may contribute to vaginal cuff dehiscence, and proposed preventative methods at the time of RA-TLH to reduce this complication. CONCLUSION Vaginal cuff dehiscence with associated evisceration of intraabdominal contents is a potentially severe complication of hysterectomy. We recommend counseling patients who undergo RA-TLH to abstain from vaginal intercourse for a minimum of 8–12 weeks.

Image-Based 3D Treatment Planning for Vaginal Cylinder Brachytherapy: Dosimetric Effects of Bladder Filling on Organs at Risk  

SciTech Connect

Purpose: To investigate the dosimetric effects of bladder filling on organs at risk (OARs) using three-dimensional image-based treatment planning for vaginal cylinder brachytherapy. Methods and Materials: Twelve patients with endometrial or cervical cancer underwent postoperative high-dose rate vaginal cylinder brachytherapy. For three-dimensional planning, patients were simulated by computed tomography with an indwelling catheter in place (empty bladder) and with 180 mL of sterile water instilled into the bladder (full bladder). The bladder, rectum, sigmoid, and small bowel (OARs) were contoured, and a prescription dose was generated for 10 to 35 Gy in 2 to 5 fractions at the surface or at 5 mm depth. For each OAR, the volume dose was defined by use of two different criteria: the minimum dose value in a 2.0-cc volume receiving the highest dose (D{sub 2cc}) and the dose received by 50% of the OAR volume (D{sub 50%}). International Commission on Radiation Units and Measurements (ICRU) bladder and rectum point doses were calculated for comparison. The cylinder-to-bowel distance was measured using the shortest distance from the cylinder apex to the contoured sigmoid or small bowel. Statistical analyses were performed with paired t tests. Results: Mean bladder and rectum D{sub 2cc} values were lower than their respective ICRU doses. However, differences between D{sub 2cc} and ICRU doses were small. Empty vs. full bladder did not significantly affect the mean cylinder-to-bowel distance (0.72 vs. 0.92 cm, p = 0.08). In contrast, bladder distention had appreciable effects on bladder and small bowel volume dosimetry. With a full bladder, the mean small bowel D{sub 2cc} significantly decreased from 677 to 408 cGy (p = 0.004); the mean bladder D{sub 2cc} did not increase significantly (1,179 cGy vs. 1,246 cGy, p = 0.11). Bladder distention decreased the mean D{sub 50%} for both the bladder (441 vs. 279 cGy, p = 0.001) and the small bowel (168 vs. 132 cGy, p = 0.001). Rectum and sigmoid volume doses were not affected by bladder filling. Conclusions: In high-dose rate vaginal cylinder brachytherapy, treatment with a distended bladder preferentially reduces high dose to the small bowel around the vaginal cuff without a significant change in dose to the bladder, rectum, or sigmoid.

Vaginal brachytherapy alone is sufficient adjuvant treatment of surgical stage I endometrial cancer  

SciTech Connect

Purpose To determine the efficacy and complications of adjuvant vaginal high-dose-rate brachytherapy alone for patients with Stage I endometrial cancer in whom complete surgical staging had been performed. Methods and Materials Between April 1998 and March 2004, 100 patients with Stage I endometrial cancer underwent surgical staging (total abdominal hysterectomy and bilateral salpingo-oophorectomy with pelvic {+-} paraaortic nodal sampling) and postoperative vaginal high-dose-rate brachytherapy at our institution. The total dose was 2100 cGy in three fractions. Results With a median follow-up of 23 months (range 2-62), no pelvic or vaginal recurrences developed. All patients underwent pelvic dissection, and 42% underwent paraaortic nodal dissection. A median of 29.5 pelvic nodes (range 1-67) was removed (84% had >10 pelvic nodes removed). Most patients (73%) had endometrioid (or unspecified) adenocarcinoma, 16% had papillary serous carcinoma, and 11% had other histologic types. The International Federation of Gynecology and Obstetrics stage and grade was Stage IA, grade III in 5; Stage IB, grade I, II, or III in 6, 27, or 20, respectively; and Stage IC, grade I, II, or III in 13, 17, or 10, respectively. The Common Toxicity Criteria (version 2.0) complications were mild (Grade 1-2) and consisted primarily of vaginal mucosal changes, temporary urinary irritation, and temporary diarrhea. Conclusion Adjuvant vaginal high-dose-rate brachytherapy alone may be a safe and effective alternative to pelvic external beam radiotherapy for surgical Stage I endometrial cancer.

Adjuvant vaginal brachytherapy as a part of management in early endometrial cancer  

PubMed Central

Endometrial cancer is the most frequent cancer of female genital tract. Metro- and menorrhagia or postmenopausal bleeding results in its early presentation. It allows radical treatment. However, controversies remain on surgery coverage or adjuvant therapies in early endometrial women cancer. Optimal management should minimize intervention instead of aggressive approach, as showed by recent studies. There is a role for brachytherapy as an adjuvant irradiation. Crucial publications including PORTEC-1, GOG 99, MRC ASTEC, ASTEC/EN.5, PORTEC-2 or Italian lymphadenectomy trial are discussed. Moreover, there is attention paid on adjuvant vaginal brachytherapy analyses for the past fifteen years.

A Novel Low Dose Fractionation Regimen for Adjuvant Vaginal Brachytherapy in Early Stage Endometrial Cancer  

PubMed Central

Purpose To evaluate local control, survival and toxicity in patients with early-stage endometrioid adenocarcinoma of the uterus treated with adjuvant high-dose-rate (HDR) vaginal brachytherapy (VB) alone using a novel low dose regimen Methods We reviewed records of 414 patients with stage IA to stage II endometrial adenocarcinoma treated with VB alone from 2005 to 2011. Of these, 157 patients with endometrioid histology received 24 Gy in 6 fractions of HDR vaginal cylinder brachytherapy and constitute the study population. Dose was prescribed at the cylinder surface and delivered twice weekly in the post-operative setting. Local control and survival rates were calculated by the Kaplan-Meier method. Results All 157 patients completed the prescribed course of VB. Median follow-up time was 22.8 months (range, 1.5–76.5). Two patients developed vaginal recurrence, one in the periurethral region below the field and one in the fornix after treatment with a 2.5-cm cylinder. Three patients developed regional recurrence in the para-aortic region. Two patients developed distant metastasis (lung and carcinomatosis). The 2-year rate of vaginal control was 98.6%, locoregional control was 97.9% and disease-free survival was 96.8%. The 2-year overall survival rate was 98.7%. No Grade 2 or higher vaginal, gastrointestinal, genitourinary or skin long-term toxicity was reported for any patient. Conclusion Vaginal brachytherapy alone in early-stage endometrial cancer provides excellent results in terms of locoregional control and disease-free survival. The fractionation scheme of 24 Gy in 6 fractions prescribed to the cylinder surface was well-tolerated with minimal late toxicity.

A novel method for vaginal cylinder treatment planning: a seamless transition to 3D brachytherapy  

PubMed Central

Purpose Standard treatment plan libraries are often used to ensure a quick turn-around time for vaginal cylinder treatments. Recently there is increasing interest in transitioning from conventional 2D radiograph based brachytherapy to 3D image based brachytherapy, which has resulted in a substantial increase in treatment planning time and decrease in patient through-put. We describe a novel technique that significantly reduces the treatment planning time for CT-based vaginal cylinder brachytherapy. Material and methods Oncentra MasterPlan TPS allows multiple sets of data points to be classified as applicator points which has been harnessed in this method. The method relies on two hard anchor points: the first dwell position in a catheter and an applicator configuration specific dwell position as the plan origin and a soft anchor point beyond the last active dwell position to define the axis of the catheter. The spatial location of various data points on the applicator's surface and at 5 mm depth are stored in an Excel file that can easily be transferred into a patient CT data set using window operations and then used for treatment planning. The remainder of the treatment planning process remains unaffected. Results The treatment plans generated on the Oncentra MasterPlan TPS using this novel method yielded results comparable to those generated on the Plato TPS using a standard treatment plan library in terms of treatment times, dwell weights and dwell times for a given optimization method and normalization points. Less than 2% difference was noticed between the treatment times generated between both systems. Using the above method, the entire planning process, including CT importing, catheter reconstruction, multiple data point definition, optimization and dose prescription, can be completed in ~5–10 minutes. Conclusion The proposed method allows a smooth and efficient transition to 3D CT based vaginal cylinder brachytherapy planning.

Vulval and Vaginal Rhabdomyosarcoma in Children: Update and Reappraisal of Institut Gustave Roussy Brachytherapy Experience  

SciTech Connect

Purpose: To report the Institut Gustave Roussy brachytherapy (BT) experience in the management of vulval and vaginal rhabdomyosarcoma with special emphasis on long-term outcome. Patients and Methods: Between 1971 and 2005, the data concerning 39 girls who had undergone BT as a part of their treatment were retrospectively analyzed. Of the 39 girls, 20 had been treated before 1990, when the BT volume encompassed the initial tumor extension. After 1990, only residual disease was included in the BT volume. Side effects were classified using the Common Terminology Criteria for Adverse Events, version 3.0. Results: The median age was 16.3 months at diagnosis. Vaginal or vulvar rhabdomyosarcoma was diagnosed in 26 and 6 patients, respectively. The median follow-up was 8.4 years. The 5-year overall survival rate was 91%. Of the 39 patients, 6 developed a relapse. Of the 20 patients treated before 1990, 6 experienced Grade 1-2 renal/genitourinary function symptoms and 75% developed sequelae, in the form of vaginal or urethral sclerosis or stenosis. Four patients received follow-up treatment for psychological disorders. Of the 19 patients treated after 1990, 2 developed acute side effects, with maximal Grade 1-2 renal/genitourinary function symptoms, and 20% developed vaginal or urethral sclerosis or stenosis. Two cases of psychological disturbances were also documented. Conclusion: Reducing the BT volume coverage, better indications for surgery, and more efficient chemotherapy, all combined within a multidisciplinary approach, tended to improve results in terms of both survival and long-term sequelae.

High Dose-Rate Intracavitary Brachytherapy for Cervical Carcinomas With Lower Vaginal Infiltration  

SciTech Connect

Purpose: This report presents the clinical applications of an automated treatment-planning program of high-dose-rate intracavitary brachytherapy (HDR-ICBT) for advanced uterine cervical cancer infiltrating the parametrium and the lower vagina. Methods and Materials: We adopted HDR-ICBT under optimized dose distribution for 22 cervical cancer patients with tumor infiltration of the lower half of the vagina. All patients had squamous cell carcinoma with International Federation of Gynecology and Obstetrics clinical stages IIB-IVA. After whole pelvic external beam irradiation with a median dose of 30.6 Gy, a conventional ICBT was applied as 'pear-shaped' isodose curve. Then 3-4 more sessions per week of this new method of ICBT were performed. With a simple determination of the treatment volume, the cervix-parametrium, and the lower vagina were covered automatically and simultaneously by this program, that was designated as 'utero-vaginal brachytherapy'. The mean follow-up period was 87.4 months (range, 51.8-147.9 months). Results: Isodose curve for this program was 'galaxy-shaped'. Five-year local-progression-free survival and overall survival rates were 90.7% and 81.8%, respectively. Among those patients with late complications higher than Grade 2 Radiation Therapy Oncology Group/European Organization for Research and Treatment of Cancer morbidity score, only one (4.5%) developed severe proctitis. Conclusions: Because of the favorable treatment outcomes, this treatment-planning program with a simplified target-volume based dosimetry was proposed for cervical cancer with lower vaginal infiltration.

Modified Fletcher's 3-channel brachytherapy system with vaginal line source loading versus uterine tandem and vaginal cylinder system in Stage IIIA cervical cancer  

PubMed Central

Purpose The uterine tandem with open-ended vaginal cylinder is the most commonly used brachytherapy system for Federation Internationale de Gynecologie et d'Obstetrique (FIGO) Stage IIIA cervix cancer at the National Cancer Centre, Singapore. Without the 3-channel ovoid system, the dose to the parametrium is often compromised. In this study, a vaginal cylinder that could potentially be incorporated with the 3-channel system was developed, hence addressing the problem of treating both the vaginal disease extension and the parametrium. Methods and materials A hollow cylinder of 3 cm in diameter was incorporated with the Fletcher's 3-channel tandem and ovoid system. Treatment plans were generated with the single tandem line source with a vaginal cylinder applicator and the modified Fletcher's system using the Abacus version 3 brachytherapy treatment planning software. A nominal dose of 5 Gy was prescribed to point H for both plans. The perpendicular distance of the 5 Gy isodose line from the uterine tandem plane at the centre of the ovoid and the vaginal cylinder plane 1 cm below the os guard were then compared. Results The 5 Gy isodose line was 1.7 cm from the uterine tandem source at the location lateral through the centre of the ovoids on the plan with the uterine tandem and vaginal cylinder system as compared to a distance of 3.3 cm using the modified 3-channel Fletcher system. The 5 Gy isodose line was 2 cm lateral to the central source at the vaginal cylinder plane 1 cm below the os guard on the uterine tandem and vaginal cylinder system as compared to a distance of 2.5 cm on the Modified-Fletcher system. This corresponds to an increase of 1.6 cm and 0.5 cm depth of treated parametrium on the uterine tandem plane and vaginal cylinder plane respectively with the modified Fletcher's applicator as compared with the single line source cylinder system. Conclusion As compared with the single uterine tandem and open-ended vaginal cylinder system, an addition of 1.6 cm of the parametrium was covered within the 5Gy isodose on the uterine tandem plane and 0.5 cm on the vaginal cylinder plane with the modified Fletcher's applicator. A feasibility study was started to address the ease of insertion of this modified Fletcher system into patients.

Sexual Function After Intracavitary Vaginal Brachytherapy for Early-Stage Endometrial Carcinoma  

PubMed Central

Objective To describe the effects of intracavitary brachytherapy (IVB) on sexual function and quality of life of women with early-stage endometrial cancer. Methods Women with International Federation of Gynecology and Obstetrics stage I to stage II endometrial cancer treated surgically with or without IVB were identified and mailed questionnaires. Quality of life and sexual function were measured using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 and the cervical cancer disease-specific module. Pertinent data from prior surgery and radiation treatments were abstracted retrospectively. Linear transformation of the survey subscale scores was conducted per European Organization for Research and Treatment of Cancer guidelines. Results Sixteen women in the IVB arm and 53 in the surgery-alone group completed the survey. Of the sexually active patients, 33% of the IVB patients and 42% of the surgery-alone patients felt their vagina was dry during sexual activity (P = 0.804) and 17% versus 20% felt their vagina was short (P = 0.884). Seventeen percent of patients in the IVB group felt their vagina was tight compared to 29% in the surgery-alone group (P = 0.891) and 0% versus 14% of patients reported pain during intercourse (P = 0.808). There was no statistically significant difference in sexual/vaginal functioning, sexual worry, or sexual enjoyment between the 2 groups. Conclusions Although both groups report vaginal changes that may affect sexual function, the patients treated with IVB reported similar outcomes on a sexual function questionnaire compared to patients treated with surgery alone.

Uncertainties in Assesment of the Vaginal Dose for Intracavitary Brachytherapy of Cervical Cancer using a Tandem-ring Applicator  

SciTech Connect

Purpose: The vagina has not been widely recognized as organ at risk in brachytherapy for cervical cancer. No widely accepted dose parameters are available. This study analyzes the uncertainties in dose reporting for the vaginal wall using tandem-ring applicators. Methods and Materials: Organ wall contours were delineated on axial magnetic resonance (MR) slices to perform dose-volume histogram (DVH) analysis. Different DVH parameters were used in a feasibility study based on 40 magnetic resonance imaging (MRI)-based treatment plans of different cervical cancer patients. Dose to the most irradiated, 0.1 cm{sup 3}, 1 cm{sup 3}, 2 cm{sup 3}, and at defined points on the ring surface and at 5-mm tissue depth were reported. Treatment-planning systems allow different methods of dose point definition. Film dosimetry was used to verify the maximum dose at the surface of the ring applicator in an experimental setup. Results: Dose reporting for the vagina is extremely sensitive to geometrical uncertainties with variations of 25% for 1 mm shifts. Accurate delineation of the vaginal wall is limited by the finite pixel size of MRI and available treatment-planning systems. No significant correlation was found between dose-point and dose-volume parameters. The DVH parameters were often related to noncontiguous volumes and were not able to detect very different situations of spatial dose distributions inside the vaginal wall. Deviations between measured and calculated doses were up to 21%. Conclusions: Reporting either point dose values or DVH parameters for the vaginal wall is based on high inaccuracies because of contouring and geometric positioning. Therefore, the use of prospective dose constraints for individual treatment plans is not to be recommended at present. However, for large patient groups treated within one protocol correlation with vaginal morbidity can be evaluated.

Dose Reduction Study in Vaginal Balloon Packing Filled With Contrast for HDR Brachytherapy Treatment;HDR; Uterine cervix cancer; Vaginal balloon packing; Contrast; Monte Carlo  

SciTech Connect

Purpose: Vaginal balloon packing is a means to displace organs at risk during high dose rate brachytherapy of the uterine cervix. We tested the hypothesis that contrast-filled vaginal balloon packing reduces radiation dose to organs at risk, such as the bladder and rectum, in comparison to water- or air-filled balloons. Methods and Materials: In a phantom study, semispherical vaginal packing balloons were filled with air, saline solution, and contrast agents. A high dose rate iridium-192 source was placed on the anterior surface of the balloon, and the diode detector was placed on the posterior surface. Dose ratios were taken with each material in the balloon. Monte Carlo (MC) simulations, by use of the MC computer program DOSXYZnrc, were performed to study dose reduction vs. balloon size and contrast material, including commercially available iodine- and gadolinium-based contrast agents. Results: Measured dose ratios on the phantom with the balloon radius of 3.4 cm were 0.922 {+-} 0.002 for contrast/saline solution and 0.808 {+-} 0.001 for contrast/air. The corresponding ratios by MC simulations were 0.895 {+-} 0.010 and 0.781 {+-} 0.010. The iodine concentration in the contrast was 23.3% by weight. The dose reduction of contrast-filled balloon ranges from 6% to 15% compared with water-filled balloon and 11% to 26% compared with air-filled balloon, with a balloon size range between 1.4 and 3.8 cm, and iodine concentration in contrast of 24.9%. The dose reduction was proportional to the contrast agent concentration. The gadolinium-based contrast agents showed less dose reduction because of much lower concentrations in their solutions. Conclusions: The dose to the posterior wall of the bladder and the anterior wall of the rectum can be reduced if the vaginal balloon is filled with contrast agent in comparison to vaginal balloons filled with saline solution or air.

The dosimetric impact of vaginal balloon-packing on intracavitary high-dose-rate brachytherapy for gynecological cancer  

PubMed Central

Purpose We perform a clinical retrospective study to determine whether a vaginal balloon-packing system provides a dosimetric reduction to organs at risk (OARs) versus traditional gauze packing for gynecological high-dose-rate brachytherapy (HDR-BT). We also test various balloon filling materials for optimizing imaging quality. Material and methods Filling materials for balloon-packing were evaluated based on imaging quality with X-ray, computerized tomography, and magnetic resonance imaging modalities. We then retrospectively reviewed 45 HDR-BT plans of 18 patients performed with gauze packing and 39 plans of 16 patients performed with balloon-packing. Twelve patients received both gauze and balloon-packing. HDR-BT was delivered with an iridium-192 afterloader and a Fletcher-Suit-Declos-style T&O applicator. At each fraction, 3D imaging was obtained. The D2cc values of OARs were calculated, as well as ICRU-defined point doses. Results In the 84 HDR fractions reviewed, vaginal balloon-packing provides statistically equivalent doses to rectum, bladder, and sigmoid compared to gauze packing. On average balloon-packing produced average reductions of 3.3% and 6.9% in the rectal and sigmoid D2cc doses and an increase of 3.2% to the bladder D2cc dose (normalized to prescription dose), although none of these values were statistically significant for the twelve patients who received both gauze and balloon-packing (32 and 40 total fractions, respectively). Conclusions In the 84 HDR fractions analyzed, vaginal balloon-packing is as effective as gauze packing for dose sparing to the rectum, bladder, and sigmoid. A 1: 1 solution of saline and contrast for filling material enables easy contouring for image-guided HDR with minimal artefacts.

A Monte Carlo dosimetry study of vaginal {sup 192}Ir brachytherapy applications with a shielded cylindrical applicator set  

SciTech Connect

A durable recommendation for brachytherapy treatment planning systems to account for the effect of tissue, applicator and shielding material heterogeneities exists. As different proposed approaches have not been integrated in clinical treatment planning routine yet, currently utilized systems disregard or, most commonly, do not fully account for the aforementioned effects. Therefore, it is of interest to evaluate the efficacy of current treatment planning in clinical applications susceptible to errors due to heterogeneities. In this work the effect of the internal structure as well as the shielding used with a commercially available cylindrical shielded applicator set (Nucletron part no. 084.320) for vaginal and rectum treatments is studied using three-dimensional Monte Carlo simulation for a clinical treatment plan involving seven source dwell positions of the classic microSelectron HDR {sup 192}Ir source. Results are compared to calculations of a treatment planning system (Plato BPS v.14.2.7), which assumes homogeneous water medium and applies a constant, multiplicative transmission factor only at points lying in the shadow of the shield. It is found that the internal structure of the applicator (which includes stainless steel, air and plastic materials) with no shield loaded does not affect the dose distribution relative to homogeneous water. In the unshielded side of the applicator with a 90 deg., 180 deg., or 270 deg. tungsten alloy shield loaded, an overestimation of treatment planning system calculations relative to Monte Carlo results was observed which is both shield and position dependent. While significant (up to 15%) at increased distances, which are not of major clinical importance, this overestimation does not affect dose prescription distances by more than 3%. The inverse effect of approx. 3% dose increase at dose prescription distances is observed for stainless steel shields. Regarding the shielded side of the applicator, it is shown that the default treatment planning system transmission factors for tungsten alloy result in a consistent dose overestimation thus constituting a safe approach given the nature of associated clinical applications. Stainless steel is shown to be an ineffective shielding material with transmission factors reaching up to 0.68 at increased distances irrespective of shield geometry.

Effects of prescription depth, cylinder size, treatment length, tip space, and curved end on doses in high-dose-rate vaginal brachytherapy  

SciTech Connect

Purpose: To determine the effects of the prescription depth, cylinder size, treatment length, tip space, and curved end on high-dose-rate vaginal brachytherapy (HDR-VBT) of endometrial cancer. Methods and Materials: Treatment plans were prescribed and optimized based on points at the cylinder surface or at 0.5-cm depth. Cylinder sizes ranging from 2 to 4 cm in diameter, and treatment lengths ranging from 3 to 8 cm were used. Dose points in various depths were precisely defined along the cylinder dome. The given dose and dose uniformity to a depth of interest were measured by the mean dose (MD) and standard deviation (SD), respectively, among the dose points belonging to the depth. Dose fall-off beyond the 0.5 cm treatment depth was determined by the ratio of MD at 0.75-cm depth to MD at 0.5-cm depth. Results: Dose distribution varies significantly with different prescriptions. The surface prescription provides more uniform doses at all depths in the target volume, whereas the 0.5-cm depth prescription creates larger dose variations at the cylinder surface. Dosimetric uncertainty increases significantly (>30%) with shorter tip space. Extreme hot (>150%) and cold spots (<60%) occur if no optimization points were placed at the curved end. Conclusions: Instead of prescribing to a depth of 0.5 cm, increasing the dose per fraction and prescribing to the surface with the exact surface points around the cylinder dome appears to be the optimal approach.

Comparison of high-dose-rate and low-dose-rate brachytherapy in the treatment of endometrial carcinoma  

SciTech Connect

Purpose: To compare the outcomes for endometrial carcinoma patients treated with either high-dose-rate (HDR) or low-dose-rate (LDR) brachytherapy. Methods and Materials: This study included 1,179 patients divided into LDR (1,004) and HDR groups (175). Patients with International Federation of Gynecology and Obstetrics (FIGO) surgical Stages I-III were included. All patients were treated with postoperative irradiation. In the LDR group, the postoperative dose applied to the vaginal cuff was 60-70 Gy surface doses to the vaginal mucosa. The HDR brachytherapy prescription was 6 fractions of 2 Gy each to a depth of 0.5 cm from the surface of the vaginal mucosa. Overall survival, disease-free survival, local control, and complications were endpoints. Results: For all stages combined, the overall survival, disease-free survival, and local control at 5 years in the LDR group were 70%, 69%, and 81%, respectively. For all stages combined, the overall survival, disease-free survival, and local control at 5 years in the HDR group were 68%, 62%, and 78%, respectively. There were no significant differences in early or late Grade III and IV complications in the HDR or LDR groups. Conclusion: Survival outcomes, pelvic tumor control, and Grade III and IV complications were not significantly different in the LDR brachytherapy group compared with the HDR group.

Optimized Dose Distribution of Gammamed Plus Vaginal Cylinders  

SciTech Connect

Endometrial carcinoma is the most common malignancy arising in the female genital tract. Intracavitary vaginal cuff irradiation may be given alone or with external beam irradiation in patients determined to be at risk for locoregional recurrence. Vaginal cylinders are often used to deliver a brachytherapy dose to the vaginal apex and upper vagina or the entire vaginal surface in the management of postoperative endometrial cancer or cervical cancer. The dose distributions of HDR vaginal cylinders must be evaluated carefully, so that clinical experiences with LDR techniques can be used in guiding optimal use of HDR techniques. The aim of this study was to optimize dose distribution for Gammamed plus vaginal cylinders. Placement of dose optimization points was evaluated for its effect on optimized dose distributions. Two different dose optimization point models were used in this study, namely non-apex (dose optimization points only on periphery of cylinder) and apex (dose optimization points on periphery and along the curvature including the apex points). Thirteen dwell positions were used for the HDR dosimetry to obtain a 6-cm active length. Thus 13 optimization points were available at the periphery of the cylinder. The coordinates of the points along the curvature depended on the cylinder diameters and were chosen for each cylinder so that four points were distributed evenly in the curvature portion of the cylinder. Diameter of vaginal cylinders varied from 2.0 to 4.0 cm. Iterative optimization routine was utilized for all optimizations. The effects of various optimization routines (iterative, geometric, equal times) was studied for the 3.0-cm diameter vaginal cylinder. The effect of source travel step size on the optimized dose distributions for vaginal cylinders was also evaluated. All optimizations in this study were carried for dose of 6 Gy at dose optimization points. For both non-apex and apex models of vaginal cylinders, doses for apex point and three dome points were higher for the apex model compared with the non-apex model. Mean doses to the optimization points for both the cylinder models and all the cylinder diameters were 6 Gy, matching with the prescription dose of 6 Gy. Iterative optimization routine resulted in the highest dose to apex point and dome points. The mean dose for optimization point was 6.01 Gy for iterative optimization and was much higher than 5.74 Gy for geometric and equal times routines. Step size of 1 cm gave the highest dose to the apex point. This step size was superior in terms of mean dose to optimization points. Selection of dose optimization points for the derivation of optimized dose distributions for vaginal cylinders affects the dose distributions.

Comparative dosimetric and radiobiological assessment among a nonstandard RapidArc, standard RapidArc, classical intensity-modulated radiotherapy, and 3D brachytherapy for the treatment of the vaginal vault in patients affected by gynecologic cancer  

SciTech Connect

To evaluate a nonstandard RapidArc (RA) modality as alternative to high-dose-rate brachytherapy (HDR-BRT) or IMRT treatments of the vaginal vault in patients with gynecological cancer (GC). Nonstandard (with vaginal applicator) and standard (without vaginal applicator) RapidArc plans for 27 women with GC were developed to compare with HDR-BRT and IMRT. Dosimetric and radiobiological comparison were performed by means of dose-volume histogram and equivalent uniform dose (EUD) for planning target volume (PTV) and organs at risk (OARs). In addition, the integral dose and the overall treatment times were evaluated. RA, as well as IMRT, results in a high uniform dose on PTV compared with HDR-BRT. However, the average of EUD for HDR-BRT was significantly higher than those with RA and IMRT. With respect to the OARs, standard RA was equivalent of IMRT but inferior to HDR-BRT. Furthermore, nonstandard RA was comparable with IMRT for bladder and sigmoid and better than HDR-BRT for the rectum because of a significant reduction of d{sub 2cc}, d{sub 1cc}, and d{sub max} (p < 0.01). Integral doses were always higher than HDR-BRT, although the values were very low. Delivery times were about the same and more than double for HDR-BRT compared with IMRT and RA, respectively. In conclusion, the boost of dose on vaginal vault in patients affected by GC delivered by a nonstandard RA technique was a reasonable alternative to the conventional HDR-BRT because of a reduction of delivery time and rectal dose at substantial comparable doses for the bladder and sigmoid. However HDR-BRT provides better performance in terms of PTV coverage as evidenced by a greater EUD.

Radiation therapy for primary vaginal carcinoma  

PubMed Central

Brachytherapy plays a significant role in the management of cervical cancer, but the clinical significance of brachytherapy in the management of vaginal cancer remains to be defined. Thus, a single institutional experience in the treatment of primary invasive vaginal carcinoma was reviewed to define the role of brachytherapy. We retrospectively reviewed the charts of 36 patients with primary vaginal carcinoma who received definitive radiotherapy between 1992 and 2010. The treatment modalities included high-dose-rate intracavitary brachytherapy alone (HDR-ICBT; two patients), external beam radiation therapy alone (EBRT; 14 patients), a combination of EBRT and HDR-ICBT (10 patients), or high-dose-rate interstitial brachytherapy (HDR-ISBT; 10 patients). The median follow-up was 35.2 months. The 2-year local control rate (LCR), disease-free survival (DFS), and overall survival (OS) were 68.8%, 55.3% and 73.9%, respectively. The 2-year LCR for Stage I, II, III and IV was 100%, 87.5%, 51.5% and 0%, respectively (P = 0.007). In subgroup analysis consisting only of T2–T3 disease, the use of HDR-ISBT showed marginal significance for favorable 5-year LCR (88.9% vs 46.9%, P = 0.064). One patient each developed Grade 2 proctitis, Grade 2 cystitis, and a vaginal ulcer. We conclude that brachytherapy can play a central role in radiation therapy for primary vaginal cancer. Combining EBRT and HDR-ISBT for T2–T3 disease resulted in good local control.

Endobronchial cuff pressures.  

PubMed

In 20 adult patients (18 male) who presented for thoracotomy, the trachea was intubated using Mallinckrodt disposable double-lumen tubes (18 large and two medium). The endobronchial cuff was inflated by a trained operating department assistant using an air-filled syringe. The volume of air and the initial endobronchial cuff pressure were measured. The minimum cuff pressure required to prevent respiratory gas leakage from the isolated lung was measured also and maintained using the Cardiff Cuff Controller. Mean initial cuff pressure was 69.3 (SEM 6.0) mm Hg, whereas the mean minimum cuff pressure was 29.5 (4.0) mm Hg (P < 0.0001). The results suggest that the method described of inflating the endobronchial cuff may lead to overinflation and subsequent excessive pressure on the endobronchial wall. PMID:8318334

Treatment technique training needs theoretical and practical knowledge allowing proposing the right treatment for the right patient, but also allowing performing the technical gesture in the best conditions for an optimal result with a maximal security. The evolution of the brachytherapy techniques needs the set up of specific theoretical and practical training sessions. The present article focuses on the importance of the brachytherapy training as well as the different means currently available for the young radiation oncologist community for perfecting their education. National and international trainings are presented. The role of the simulation principle in the frame of brachytherapy is also discussed. Even if brachytherapy is not always an easy technique, its efficacy and its medico-economical impact need to be passed down to motivated students with the implementation of relevant educational means.

The surgical treatments--vented, open rotator cuff interval, reconstruction, and coracoacromial ligament transfer--had an effect compared to the intact shoulders on the inferior stiffness (P = .00002) and on the anteroposterior stiffness (P = .00031). The difference between the stiffness of the reconstructed rotator cuff interval compared to the coracoacromial ligament transfer was significant for loading in the AP direction (P = .006) and for loading in the inferior direction (P = .005).

Peritonitis due to a peritoneal vaginal fistula.  

PubMed

Development of a peritoneal vaginal fistula is rare and presents a unique clinical scenario, since the fistula wall is less likely to spontaneously heal because of the increased intra-abdominal pressure in the abdomen from the peritoneal fluid. Catheter removal and surgical repair of the fistula are required. Early catheter removal contributes to peritoneal membrane preservation. In the case of M.T., the most likely explanation was that the peritoneal fluid was leaking through the vaginal cuff created during the surgical procedure in 2004. Early identification of this problem may have prevented the numerous complications and lengthy hospitalization. Suspicion should be raised in any patient who complains of vaginal leakage or if the passage of "urine" in a previously anuric patient is noted. Early assessment and evaluation along with prompt catheter removal can help reduce complications and preserve the peritoneal membrane. This case also emphasizes that prompt catheter removal is very important in cases of fungal peritonitis. PMID:20462078

Histopathology of rotator cuff tears.  

PubMed

The pathogenesis of rotator cuff tears is multifactorial. Tendon abnormalities of the rotator cuff include alteration of collagen fiber structure, tenocytes, cellularity, and vascularity. Ruptured tendons show marked collagen degeneration and disordered arrangement of collagen fibers. Fibroblast population decreases as the size of the tear in the rotator cuff increases. The larger fibroblast population seen in the smaller tears is also actively proliferating and is part of an active reparative process. Inflammatory cell infiltrate correlates inversely to rotator cuff tear size in the torn supraspinatus tendon samples, with larger tears showing a marked reduction in all cell types. As tear size increase, there is also a progressive decrease in the number of blood vessels. Whether rotator cuff tear heals spontaneously is an important pathologic and clinical question. Histologic changes indicative of repair and inflammation lead to consider biological options in addition to biomechanical treatment of the rotator cuff tears. PMID:21822106

Vaginal agenesis is not rare. Many ingenious procedures have been devised for its correction; some are simple, and some are complicated. Not enough emphasis has been placed on the emotional aspects when patients with this problem are treated. Proper timing of the operation and selection of the best procedure are discussed. We feel that procedure of choice is the simplest, least dangerous one which will give good results in the individual patient. Rather than using the same routine procedure in each patient, we fitted the treatment to each patient. Our experience, particularly with the simple vulvovaginoplasty technique, is given. Postoperative support and encouragement are needed to have a successful outcome. PMID:1244753

Revision rotator cuff repair.  

PubMed

The management of patients with a failed rotator cuff repair is challenging. Revision arthroscopic repairs can be entertained in select patients when realistic outcomes are understood. Complete evaluation of the shoulder is needed to identify and treat potential confounding pain generators. The ability to determine if a recurrent tear is repairable is difficult, because there are no established criteria to make this determination. If a recurrent tear is found to be repairable, the results of the surgery are encouraging, although persistent limitations in shoulder function are common. Strategies to improve the rates of tendon healing should be used and include the use of stronger repair constructs, when possible, and implementation of a slower rehabilitation progression.

Vaginal-Assisted Laparoscopic Radical Hysterectomy: Rationale, Technique, Results

Objective: Total laparoscopic radical hysterectomy (TLRH) makes it difficult to resect adequate vaginal cuff according to tumor size and to avoid tumor spread after opening the vagina. Laparoscopic-assisted radical vaginal hysterectomy (LARVH) is associated with higher risk for urologic complications. Methods: The vaginal-assisted laparoscopic radical hysterectomy (VALRH) technique comprises 3 steps: (1) comprehensive laparoscopic staging, (2) creation of a tumor-adapted vaginal cuff, and (3) laparoscopic transsection of parametria. We retrospectively analyzed data of 122 patients who underwent VALRH for early stage cervical cancer (n=110) or stage II endometrial cancer (n=12) between January 2007 and December 2009 at Charité University Berlin. Results: All patients underwent VALRH without conversion. Mean operating time was 300 minutes, and mean blood loss was 123cc. On average, 36 lymph nodes were harvested. Intra- and postoperative complication rates were 0% and 13.1%, respectively. Resection was in sound margins in all patients. After median follow-up of 19 months, disease-free survival and overall survival for all 110 cervical cancer patients was 94% and 98%, and for the subgroup of patients (n=90) with tumors ?pT1b1 N0 V0 L0/1 R0, 97% and 98%, respectively. Conclusion: VALRH is a valid alternative to abdominal radical hysterectomy and LARVH in patients with early-stage cervical cancer and endometrial cancer stage II with minimal intraoperative complications and identical oncologic outcomes.

PubMed

Bacteria are the most frequently detected agents in women, clinically complaining of vaginal discharge. The studies have shown that the vaginal microflora of women with bacterial vaginitis have altered from Lactobacillus spp. to various anaerobic bacteria. Gardnerella vaginalis is found in vaginal flora of women with bacterial vaginitis as well as in healthy women, while anaerobic bacteria such as Mobiluncus and Prevotella are the causative agents for bacterial vaginosis. For the laboratory diagnosis of bacterial vaginitis, direct microscopy is one of the most commonly used methods, and for this purpose cervicovaginal smears are examined by staining Papanicolaou and Gram stains. Because of the demonstration of bacterial vaginitis in association with the obstetric diseases such as preterm labor and postpartum endometritis, is a risk factor, its importance has increased recently. In this review article, the microorganisms that cause bacterial vaginitis, their biological characteristics, and the diagnostic laboratory methods of infection, have been discussed. PMID:12838684

[Rupture of the rotator cuff].  

PubMed

Reconstructive surgery of rotator cuff tears tries to restore a stable center of rotation in the shoulder joint. Both the classic technique of open surgery and the arthroscopic technique are employed to reconstruct the rotator cuff. This review tries to answer the question which of both surgical techniques is superior by a review of the literature. The recent literature demonstrates a shorter follow-up period for publications concerning arthroscopic reconstruction (mean 3 years) in comparison to open surgery, where follow-up is in mean 6.2 years. Overall arthroscopic surgery achieves good and excellent results between 68 to 96%, open reconstruction between 77 and 91%. Longevity of reconstructed rotator cuffs especially in large tears seems to be significantly shorter if an arthroscopic technique was used. Several authors mentioned size of tear as a major factor influencing longevity. However in patients treated arthroscopically despite rerupture of the rotor cuff patient's satisfaction and clinical outcome is still very good in short-term follow-up. In case of a complete tear of one tendon of the rotator cuff the arthroscopic technique seems to be superior. If large tears occur (two or three tendons) the open surgical technique may be more reliable with regard to longevity of the repair. For the future it seems necessary to obtain long-term results to be able to compare both principles of reconstruction of the rotator cuff. Furthermore these future studies should include quality of life scores as measurements tools besides the already employed parameters as size of the tear, age at surgery, patient satisfaction and outcome scores.

A Novel Device for Intravaginal Electronic Brachytherapy  

SciTech Connect

Purpose: Postoperative intravaginal brachytherapy for endometrial carcinoma is usually performed with {sup 192}Ir high-dose rate (HDR) afterloading. A potential alternative is treatment with a broadband 50kV X-ray point source, the advantage being its low energy and the consequential steep dose gradient. The aim of this study was to create and evaluate a homogeneous cylindrical energy deposition around a newly designed vaginal applicator. Methods and Materials: To create constant isodose layers along the cylindrical plastic vaginal applicator, the source (INTRABEAM system) was moved in steps of 17-19.5 mm outward from the tip of the applicator. Irradiation for a predetermined time was performed at each position. The axial shift was established by a stepping mechanism that was mounted on a table support. The total dose/dose distribution was determined using film dosimetry (Gafchromic EBT) in a 'solid water' phantom. The films were evaluated with Mathematica 5.2 and OmniPro-I'mRT 1.6. The results (dose D0/D5/D10 in 0/5/10 mm tissue depth) were compared with an {sup 192}Ir HDR afterloading plan for multiple sampling points around the applicator. Results: Three different dose distributions with lengths of 3.9-7.3 cm were created. The irradiation time based on the delivery of 5/7 Gy to a 5 mm tissue depth was 19/26 min to 27/38 min. D0/D5/D10 was 150%/100%/67% for electronic brachytherapy and 140%/100%/74% for the afterloading technique. The deviation for repeated measurements in the phantom was <7%. Conclusions: It is possible to create a homogeneous cylindrical dose distribution, similar to {sup 192}Ir HDR afterloading, through the superimposition of multiple spherical dose distributions by stepping a kilovolt point source.

Vaginal evisceration after a pelvic operation is a rare gynecological emergency. When intercourse is the cause, most cases occur within 1 year of surgery. A 53-year-old woman presented to the emergency room for vaginal evisceration half a day after the first postoperative occurrence of intercourse 3 years after an abdominal hysterectomy and bilateral salpingo-oophorectomy. In an emergency laparotomy, the protruding small bowel was replaced within the abdominal cavity. The avulsed vaginal cuff, which measured 6 cm in length and had atrophic but non-necrotic margins, was sutured. Women who go for long periods without intercourse after a hysterectomy, especially post-menopausal women, should be made aware of unrecognized vaginal atrophy that could, in some cases, lead to rupture and evisceration during the next occurrence of intercourse.

INTRODUCTION: The cuff-leak test has been proposed as a simple method to predict the occurrence of post-extubation stridor. The test is performed by cuff deflation and measuring the expired tidal volume a few breaths later (VT). The leak is calculated as the difference between VT with and without a deflated cuff. However, because the cuff remains deflated throughout the respiratory

Prospective multi-center trial utilizing electronic brachytherapy for the treatment of endometrial cancer  

PubMed Central

Background A modified form of high dose rate (HDR) brachytherapy has been developed called Axxent Electronic Brachytherapy (EBT). EBT uses a kilovolt X-ray source and does not require treatment in a shielded vault or a HDR afterloader unit. A multi-center clinical study was carried out to evaluate the success of treatment delivery, safety and toxicity of EBT in patients with endometrial cancer. Methods A total of 15 patients with stage I or II endometrial cancer were enrolled at 5 sites. Patients were treated with vaginal EBT alone or in combination with external beam radiation. Results The prescribed doses of EBT were successfully delivered in all 15 patients. From the first fraction through 3 months follow-up, there were 4 CTC Grade 1 adverse events and 2 CTC Grade II adverse events reported that were EBT related. The mild events reported were dysuria, vaginal dryness, mucosal atrophy, and rectal bleeding. The moderate treatment related adverse events included dysuria, and vaginal pain. No Grade III or IV adverse events were reported. The EBT system performed well and was associated with limited acute toxicities. Conclusions EBT shows acute results similar to HDR brachytherapy. Additional research is needed to further assess the clinical efficacy and safety of EBT in the treatment of endometrial cancer.

Current biomechanical concepts for rotator cuff repair.  

PubMed

For the past few decades, the repair of rotator cuff tears has evolved significantly with advances in arthroscopy techniques, suture anchors and instrumentation. From the biomechanical perspective, the focus in arthroscopic repair has been on increasing fixation strength and restoration of the footprint contact characteristics to provide early rehabilitation and improve healing. To accomplish these objectives, various repair strategies and construct configurations have been developed for rotator cuff repair with the understanding that many factors contribute to the structural integrity of the repaired construct. These include repaired rotator cuff tendon-footprint motion, increased tendon-footprint contact area and pressure, and tissue quality of tendon and bone. In addition, the healing response may be compromised by intrinsic factors such as decreased vascularity, hypoxia, and fibrocartilaginous changes or aforementioned extrinsic compression factors. Furthermore, it is well documented that torn rotator cuff muscles have a tendency to atrophy and become subject to fatty infiltration which may affect the longevity of the repair. Despite all the aforementioned factors, initial fixation strength is an essential consideration in optimizing rotator cuff repair. Therefore, numerous biomechanical studies have focused on elucidating the strongest devices, knots, and repair configurations to improve contact characteristics for rotator cuff repair. In this review, the biomechanical concepts behind current rotator cuff repair techniques will be reviewed and discussed. PMID:23730471

Biologically enhanced healing of the rotator cuff.  

PubMed

Failure of rotator cuff repair is a well-documented problem. Successful repair is impeded by muscle atrophy, fat infiltration, devascularization, and scar tissue formation throughout the fibrocartilagenous transition zone. This case study exemplifies a technique to biologically augment rotator cuff healing. Clinically, pain and function improved. Postoperative magnetic resonance imaging evaluation confirmed construct integrity. Biological enhancement of the healing process and physiologically based alterations in rehabilitation protocols can successfully treat complicated rotator cuff tears. Prospective studies with larger sample sizes and continued follow-up are necessary to assess the definitive efficacy of this treatment modality. PMID:22691639

Ranking among the most prevalent of shoulder disorders, lesions involving shoulder rotator cuff strike million of patients in the United States at different points in their lives. Despite the fact that rotator cuff disease is a very common cause of pain and disability of the upper arm, a high proportion of patients is asymptomatic and unaware of performing daily living activities despite of a shoulder lesion. Given these drawbacks, surgeons are trying exploring whether conservative treatment is a viable option for the management of these injuries.

Of the 31 recommendations made by the work group, 19 were determined to be inconclusive because of the absence of definitive evidence. Of the remaining recommendations, four were classified as moderate grade, six as weak, and two as consensus statements of expert opinion. The four moderate-grade recommendations include suggestions that exercise and nonsteroidal anti-inflammatory drugs be used to manage rotator cuff symptoms in the absence of a full-thickness tear, that routine acromioplasty is not required at the time of rotator cuff repair, that non-cross-linked, porcine small intestine submucosal xenograft patches not be used to manage rotator cuff tears, and that surgeons can advise patients that workers' compensation status correlates with less favorable outcomes after rotator cuff surgery.

Rotator cuff tear measurement by arthropneumotomography  

SciTech Connect

Five years of experience with a method of shoulder arthrography using upright tomography in cases of suspected or known rotator cuff tears has demonstrated its effectiveness. The value of the procedure lies in its ability to demonstrate the size of the cuff tear and the thickness of the remaining cuff tissue. This information provides the surgeon with a preoperative estimate of the difficulty of the repair and the prognosis for a good functional recovery. In 33 cases, there was good correlation between the upright thin-section tomogram findings and the surgical results. The tomograms provided better information about the size of the tear and the quality of the remaining cuff than did plain arthrograms.

Management of vaginal agenesis.  

PubMed

Rokitansky syndrome and complete androgen insensitivity syndrome are the most common causes of vaginal agenesis. Treatment should be deferred until adolescence to allow informed consent and compliance. The best treatment for vaginal agenesis remains controversial although vaginal dilation therapy is still widely considered the first line treatment because success rates are high and associated risks are low. A variety of surgical options are also available, each with enthusiastic proponents. Long-term outcome studies on most surgical techniques, however, are still lacking and until recently most studies have reported on success rate in terms of anatomical success only, without including sexual function. Moreover, the medical literature lacks prospective comparative outcome studies, meaning that current choice of surgical procedure relies greatly on the surgeon's preference and experience.

Clinical examination of the rotator cuff.  

PubMed

Rotator cuff tears are the leading cause of shoulder pain and shoulder-related disability and account for 4.5 million physician visits in the United States annually. A careful history and structured physical examination are often sufficient for diagnosing rotator cuff disorders. We are not aware of a clinical review article that presents a structured physical examination protocol of the rotator cuff for the interested clinician. To fill this void, we present a physical examination protocol developed on the basis of review of prior literature and our clinical experience from dedicated shoulder practices. Our protocol includes range of motion testing by using a goniometer, strength testing by using a dynamometer, and select special tests. Among the many tests for rotator cuff disorders that have been described, we chose ones that have been more thoroughly assessed for sensitivity and specificity. This protocol can be used to isolate the specific rotator cuff tendon involved. The protocol can typically be completed in 15 minutes. We also discuss the clinical implications and limitations of the physical examination maneuvers described in our protocol. This protocol is thorough yet time efficient for a busy clinical practice. It is useful in the diagnosis of rotator cuff tears, impingement syndrome, and biceps pathology. PMID:23332909

Rotator cuff tears: pathology and repair.  

PubMed

By virtue of its anatomy and function, the rotator cuff is vulnerable to considerable morbidity, often necessitating surgical intervention. The factors contributing to cuff disease can be divided into those extrinsic to the rotator cuff (most notably impingement) and those intrinsic to the cuff (age-related degeneration, hypovascularity and inflammation amongst others). In an era of emerging biologic interventions, our interventions are increasingly being modulated by our understanding of these core processes, many of which remain uncertain today. When we do intervene surgically, the techniques we employ are particularly challenging in the context of the tremendous pace of advancement. Several recent studies have shown that arthroscopic repair gives similar functional results to that of mini-open and open procedures, with all the benefits of minimally invasive surgery. However, the 'best' repair construct remains unknown, with wide variations in surgeon preference. Here we present a literature review encompassing recent developments in our understanding of basic science in rotator cuff disease as well as an up-to-date evidence-based comparison of different techniques available to the surgeon for cuff repair.

Medial rotator cuff failure after arthroscopic double-row rotator cuff repair.

Persistent tendon defects after rotator cuff repair are not uncommon. Recently, the senior author has identified a subset of 5 patients (mean age, 52 years; range, 42 to 59 years) after arthroscopic double-row rotator cuff repair who showed an unusual mechanism of tendon failure. In these patients the tendon footprint appears well fixed to the greater tuberosity with normal thickness. However, medial to the intact footprint, the tendon is torn with full-thickness defects through the rotator cuff. All patients were involved in Workers' Compensation claims. Magnetic resonance arthrography showed an intact cuff footprint but dye leakage in all patients. Revision surgery was performed at a mean of 8.6 months after the index procedure and showed an intact rotator cuff footprint but cuff failure medial to the footprint. Four patients had repair of the defects by tendon-to-tendon side-to-side sutures, whereas one did not undergo repair. Medial-row failure of the rotator cuff is a previously unreported mechanism of failure after double-row rotator cuff repair. Given the small number of patients in this study, it is unclear whether these defects are symptomatic. However, repair of these defects resulted in improvement in pain in 4 of 5 patients.

Adjuvant and definitive radiation therapy for primary carcinoma of the vagina using brachytherapy and external beam radiation therapy  

PubMed Central

Purpose To report the outcomes of patients receiving vaginal brachytherapy and/or external beam radiation therapy (EBRT) for primary vaginal cancer. Material and methods Between 1983 and 2009, 63 patients received brachytherapy and/or EBRT for primary tumors of the vagina at a single tertiary center. Patient data was collected via chart review. The Kaplan-Meier method was used to calculate actuarial pelvic local control (LC), disease-free survival (DFS), overall survival (OS), and severe late toxicity rates. Acute and late toxicities were scored according to the Common Terminology Criteria for Adverse Events version 3 (CTCAE v3.0). Results Median follow up was 44.2 months. Patients with early stage disease (stages I and II) had significantly improved 5-year OS when compared to patients with locally advanced disease (stages III and IVA) (73.3 vs. 34.4%, p = 0.032). Patients with greater than 1/3 vaginal involvement had significantly worse prognosis than patients with tumors involving 1/3 or less of the vagina, with the later having superior DFS (84.0 vs. 52.4%, p = 0.007) and LC (86.9 vs. 60.4%, p = 0.018) at 5-years. Age, histology, and brachytherapy technique did not impact treatment outcomes. The 5-year actuarial grade 3 or higher toxicity rate was 23.1% (95% CI: 10.6-35.6%). Concurrent chemotherapy had no impact on outcomes or toxicity in this analysis. Conclusions Success of treatment for vaginal cancer depends primarily on disease stage, but other contributing factors such as extent of vaginal involvement and tumor location significantly impact outcomes. Treatment of vaginal cancer with primary radiotherapy yields acceptable results with reasonable toxicity rates. Management of this rare malignancy requires a multidisciplinary approach to appropriately optimize therapy.

Failed Operative Vaginal Delivery  

PubMed Central

Objective To compare maternal and neonatal outcomes in women undergoing a second stage cesarean after a trial of operative vaginal delivery with women undergoing a second stage cesarean without such an attempt. Methods This study is a secondary analysis of the women who underwent second stage cesarean. .The maternal outcomes examined included blood transfusion, endometritis, wound complication, anesthesia use, and maternal death. Infant outcomes examined included umbilical artery pH < 7.0, Apgar of 3 or less at 5 minutes, seizures within 24 hours of birth, hypoxic ischemic encephalopathy (HIE), stillbirth, skull fracture, and neonatal death. Results Of 3189 women who underwent second stage cesarean, operative vaginal delivery was attempted in 640. Labor characteristics were similar in the two groups with the exception of the admission to delivery time and cesarean indication. Those with an attempted operative vaginal delivery were more likely to undergo cesarean delivery for a non-reassuring fetal heart rate tracing (18.0% vs 13.9%, p=.01), have a wound complication (2.7% vs 1.0%; OR 2.65 95% CI 1.43–4.91), and require general anesthesia (8.0% vs 4.1%, OR 2.05 95% CI 1.44–2.91). Neonatal outcomes including umbilical artery pH less than 7.0, Apgar at or below 3 at 5 minutes, and hypoxic ischemic encephalopathy were more common for those with an attempted operative vaginal delivery. This was not significant when cases with a non-reassuring fetal heart rate tracing were removed. Conclusion Cesarean delivery after an attempt at operative vaginal delivery was not associated with adverse neonatal outcomes in the absence of a non-reassuring fetal heart rate tracing.

Brachytherapy and pancreatic cancer.  

PubMed

Advances in diagnostic and therapeutic technology have not appreciably changed the outlook of patients with pancreatic cancer. While those patients presenting with localized resectable disease have the best prognosis, local control and intra-abdominal metastases remain significant obstacles to survival. Localized chemoradiation has modestly improved median survival in localized and locally advanced disease. Patients presenting with locally advanced disease at diagnosis benefit from surgical palliation which includes biliary and gastric bypass. Intraoperative interstitial brachytherapy has been effective when utilized at laparotomy to improve local control in locally advanced disease. Advances in laparoscopic techniques have provided the ability to more accurately stage patients prior to laparotomy and perform palliative procedures without the need for laparotomy. The utilization of high-dose-rate brachytherapy has proven effective in palliating obstructive symptoms with minimal morbidity on an outpatient basis. Recent efforts have focused on preoperative chemoradiation to improve resectability in selected patients and prophylactic hepatic irradiation to reduce metastases for patients with locally advanced disease.

Fatty infiltration and rotator cuff atrophy.  

PubMed

Moderate to severe fatty infiltration and rotator cuff atrophy are commonly associated with poor clinical outcomes and failed rotator cuff repair. Numerous animal and human studies have attempted to elucidate the etiology of fatty infiltration and rotator cuff atrophy. Mechanical detachment of the tendon in rotator cuff tears is primarily responsible. Suprascapular nerve injury may also play a role. CT, MRI, and ultrasonography are used to evaluate severity. The Goutallier staging system is most commonly used to evaluate fatty infiltration, and rotator cuff atrophy is measured using multiple techniques. The presence and severity of fatty infiltration have been associated with increasing age, tear size, degree of tendon retraction, number of tendons involved (ie, massive tears), suprascapular neuropathy, and traumatic tears. Fatty infiltration is irreversible and progressive if left untreated. Slight reversal of muscle atrophy has been noted after repair in some studies. Novel therapies are currently being evaluated that may eventually allow clinicians to alter the natural history and improve patient outcomes. PMID:24084435

We have used a self-curling nerve cuff electrode to record sensory information from a cutaneous nerve. This type of cuffs has previously been used only for stimulation, but its mechanical properties could make it very suitable for recording also, since it can be fitted closer to the nerve than traditional cuffs without compromising the nerve. In this study we show

Vaginal leiomyoma in pregnancy presenting as a prolapsed vaginal mass.  

PubMed

Vaginal leiomyomas are rare benign solid tumours of the vagina. They can cause mechanical dystocia, which is a common problem in obstetrics leading to serious maternal and perinatal complications. Here we describe a patient with a vaginal leiomyoma diagnosed during the mid-trimester that could have caused dystocia. This 22-year-old woman presented with a vaginal mass and leaking vaginal fluid during pregnancy. On examination, a prolapsed, pedunculated mass, measuring 5 × 3 × 4 cm was detected in the anterior vaginal wall. Via a midline incision, the mass was easily enucleated and removed. Transvaginal surgical enucleation of the vaginal leiomyoma is usually curative and recommended as the initial treatment of choice to prevent for dystocia. Such treatment is indicated when the tumour is a potential obstacle to normal labour. PMID:23223657

Tendon transfers for irreparable rotator cuff tears.  

PubMed

Tendon transfer is one treatment option for patients with massive irreparable rotator cuff tears. Although surgical indications are not clearly defined, the traditional thought is that the ideal candidate is young and lacks significant glenohumeral arthritis. The proposed benefits of tendon transfers are pain relief and potential increase in strength. The biomechanical rationale for the procedure is to restore the glenohumeral joint force couple and possibly to restore normal shoulder kinematics. The selection of donor tendon depends on the location of the rotator cuff deficiency. Transfers of latissimus dorsi and pectoralis major tendons have been shown to consistently improve pain; however, functional benefits are unpredictable. Trapezius tendon transfer may be an alternative in patients with massive posterosuperior rotator cuff tears, although longer-term follow-up is required. PMID:23908255

Role of metalloproteinases in rotator cuff tear.  

PubMed

The role of matrix metalloproteinases (MMPs) and their inhibitors (TIMPS) in the pathophysiology of rotator cuff tears has not been established yet. Recent advances empathize about the role of MMPs and TIMPS in extracellular matrix (ECM) remodeling and degradation in rotator cuff tears pathogenesis and healing after surgical repair. An increase in MMPs synthesis and the resulting MMPs mediated alterations in the ECM of tendons have been implicated in the etiopathogenesis of tendinopathy, and there is an increase in the expression of MMPs and a decrease in TIMP messenger ribonucleic acid expression in tenocytes from degenerative or ruptured tendons. Importantly, MMPs are amenable to inhibition by cheap, safe, and widely available drugs such as the tetracycline antibiotics and bisphosphonates. A better understanding of relationship and activity of these molecules could provide better strategies to optimize outcomes of rotator cuff therapy. PMID:21822103

[Arthroscopic reconstruction of the rotor cuff].  

PubMed

Over the last years treatment of rotator cuff tears is evolving gradually from open to complete arthroscopic repair. There had been fast developments in arthroscopic techniques and instruments and there is a better understanding of biomechanical backgrounds. For a good clinical outcome it is not necessary to obtain a watertight closure in all cases but to balance the force couples in the coronal and transverse plane. There is recent discussion regarding the optimum techniques and stitches for cuff reconstruction and resulting developments in this field. To determine the individual reconstruction technique it is crucial to recognize the different tear categories. Based on these findings we are now able to treat nearly every cuff tear arthroscopically, even a retracted massive lesion. PMID:16897022

Clinical and biological aspects of rotator cuff tears.  

PubMed

Rotator cuff tears are common and are a frequent source of shoulder pain and disability. A wide variation in the prevalence of rotator cuff tears has been reported. The etiology of rotator cuff tear remains multifactorial and attempts to unify intrinsic and extrinsic theories tried to explain the etiopathogenesis of rotator cuff tears. Knowledge of the etiopathogenesis of rotator cuff tears is important to improve our therapies, surgical techniques and promote tendon repair. Several strategies have been proposed to enhance tendon healing and recently research has focused on regenerative therapies, such as Growth Factors (GFs) and Plasma Rich Platelet (PRP), with high expectations of success.

Optimization of brachytherapy dose distributions by simulated annealing.  

PubMed

An algorithm based on the method of simulated annealing is presented for optimizing brachy-therapy dose distributions. The algorithm accommodates either static configurations of multiple sources or single stepping sources, hence in principle can be used to optimize both low- and high-dose rate treatments delivered with remote afterloading equipment. Required inputs include the specification of target dose rates and dose rate limits, expressed in absolute or relative terms, at operator selected points near the treatment site. The influence of the dose rate limits can be adjusted continuously through the use of one or more penalty factors. The algorithm generates a set of integer weights, one for each available source position, which are interpreted in terms of configuration occupancy numbers for static source arrangements and relative dwell times for stepping sources. Application is made to several variations of a hypothetical low-dose rate vaginal vault planning problem involving one rectal and six applicator calculation points. The algorithm's performance for different source strengths, annealing schedules, target dose rates, dose rate limits, and values of a single penalty factor lambda was examined. With a simple annealing schedule and value of lambda = 25, the algorithm found solutions of high quality for all problem variants. The CPU time required for optimization on a Vax 11/750 computer ranged from 2 min for a single configuration to 25 min for a solution consisting of four configurations. These results support the use of simulated annealing for clinical planning of low dose rate vaginal treatments, and encourage investigation of other applications in brachytherapy. PMID:1518484

Conformal Brachytherapy Planning for Cervical Cancer Using Transabdominal Ultrasound  

SciTech Connect

Purpose: To determine if transabdominal ultrasound (US) can be used for conformal brachytherapy in cervical cancer patients. Materials and Methods: Seventy-one patients with locoregionally advanced cervix cancer treated with chemoradiation and brachytherapy were included in this study. The protocol consisted of US-assisted tandem insertion and conformal US-based planning. Orthogonal films for applicator reconstruction were also taken. A standard plan was modified to suit the US-based volume and treatment was delivered. The patient then underwent a magnetic resonance imaging (MRI) scan with the applicators in situ. Retrospectively, individual standard (STD), US, and MRI plans were extrapolated for five fractions and superimposed onto the two-dimensional sagittal MRI images for comparison. Doses to Point A, target volume, International Commission on Radiation Units and Measurements (ICRU) 38 bladder and rectal points, and individualized bowel points were calculated on original implant geometry on Plato for each planning method. Results: STD (high-dose-rate) plans reported higher doses to Point A, target volume, ICRU 38 bladder and rectal points, and individualized bowel point compared with US and MRI plans. There was a statistically significant difference between standard plans and image-based plans-STD vs. US, STD vs. MRI, and STD vs. Final-having consistent (p {<=} 0.001) respectively for target volume, Point A, ICRU 38 bladder, and bowel point. US plan assessed on two-dimensional MRI image was comparable for target volume (p = 0.11), rectal point (p = 0.8), and vaginal mucosa (p = 0.19). Local control was 90%. Late bowel morbidity (G3, G4) was <2%. Conclusions: Transabdominal ultrasound offers an accurate, quick, accessible, and cost-effective method of conformal brachytherapy planning.

[Diagnosis and treatment of rotator cuff tears].  

PubMed

A rotator cuff tear is a highly prevalent disorder, occurring in 25% of people over 60 years of age. In two thirds of patients the tear is small and asymptomatic. Acute, symptomatic cuff tears may occur in active sportsmen and women aged 30-50. There is often a considerable delay in diagnosis in this group, due to a lack of recognition by either the patient or the doctor. Recently identified risk factors for the development of cuff tear are nicotine abuse, hypercholesterolaemia, contralateral cuff tear and genetic predisposition. Conservative treatment can be very successful and consists of physical therapy and effective analgesics. Repeated steroid injections are harmful to the tendinous tissue and should be avoided. The aim of surgery is anatomical reinsertion of the ruptured tendon using an open or arthroscopic procedure. The arthroscopic procedure enables the surgeon to perform a more extensive evaluation and treatment of the joint. The arthroscopic procedure is technically more demanding than the open procedure, but seems to have a shorter rehabilitation period. PMID:21871139

[Symptomatic rotator cuff tear of the shoulder].  

PubMed

Rotator cuff tears of the shoulder are common in the middle age and elderly population and can cause chronic pain. The prevalence of rotator cuff tears in people in their 50s, 60s, 70s, and 80s is 12.8%, 25.6%, 45.8% and 50% respectively. Etiological theories for tear evolvement are divided into intrinsic (e.g. recurrent microtrauma) and extrinsic (e.g. subacromial impingement). The subacromial bursa is probably the source of pain in symptomatic patients with rotator cuff tear. It is uncertain whether the tear itself can produce pain because of the high prevalence of asymptomatic tears. The symptoms are of gradual increase in shoulder pain and weakness, however, it can happen acutely due to an injury. Difficulties in overhead activities and night pain are common. Evaluation of shoulder muscle strength can imply on cuff tear. Shoulder radiograph is essential specifically to rule out other diagnosis. Imaging such as ultrasound and magnetic resonance can further define the tear, however they should be used only if they will affect the management of the condition. Common indications for surgical repair are acute tear in a relatively young and active patient or when the treatment of symptomatic patient with chronic tear had failed. Most repairs are currently performed in an all arthroscopic technique which is minimally invasive with easier rehabilitation and less pain. PMID:22741212

Biological strategies to enhance rotator cuff healing.  

PubMed

Rotator cuff tear causes a high rate of morbidity. After surgical repair, the presence of a scar tissue reduces tendon biomechanical properties. Emerging strategies for enhancing tendon healing are growth factors, cytokines, gene therapy and tissue engineering. However their efficacy has to be proved. Growth factors help the process of tendon healing by aiding cells chemotaxis, differentiation and proliferation. Numerous growth factors, including the bone morphogenetic proteins and platelet-derived growth factor can be found during the early healing process of a rotator cuff repair. Growth factors are delivered to the repair site using tissue-engineered scaffolding, coated sutures, or dissolved in a fibrin sealant. Platelet-rich plasma is an autologous concentration of platelets and contains an high density of growth factors. There is some evidence that platelet-rich plasma may improve pain and recovery of function in a short time period, but it does not improve healing rates in rotator cuff. Thus the routine use of platelet-rich plasma in rotator cuff repair is not recommended. The addition of mesenchymal stem cells to scaffolds can lead to the production of a better quality healing tissue. Gene therapy is a gene transfer from a cell into another, in order to over-express the gene required. In this way, cultures of stem cells can over-express growth factors. Better understanding of the mechanisms of physiological tendon healing can promote the correct use of these new biological therapies for a better healing tissue. PMID:24059330

Partial-Thickness Rotator Cuff Tears  

PubMed Central

Although the incidence of partial-thickness rotator cuff tears (PTRCTs) was reported to be from 13% to 32% in cadaveric studies, the actual incidence is not yet known. The causes of PTRCTs can be explained by either extrinsic or intrinsic theories. Studies suggest that intrinsic degeneration within the rotator cuff is the principal factor in the pathogenesis of rotator cuff tears. Extrinsic causes include subacromial impingement, acute traumatic events, and repetitive microtrauma. However, acromially initiated rotator cuff pathology does not occur and extrinsic impingement does not cause pathology on the articular side of the tendon. An arthroscopic classification system has been developed based on the location and depth of the tear. These include the articular, bursal, and intratendinous areas. Both ultrasound and magnetic resonance image are reported with a high accuracy of 87%. Conservative treatment, such as subacromial or intra-articular injections and suprascapular nerve block with or without block of the articular branches of the circumflex nerve, should be considered prior to operative treatment for PTRCTs.

Heterogeneity of Vaginal Microbial Communities within Individuals? #  

PubMed Central

Recent culture-independent studies have revealed that a healthy vaginal ecosystem harbors a surprisingly complex assemblage of microorganisms. However, the spatial distribution and composition of vaginal microbial populations have not been investigated using molecular methods. Here, we evaluated site-specific microbial composition within the vaginal ecosystem and examined the influence of sampling technique in detection of the vaginal microbiota. 16S rRNA gene clone libraries were prepared from samples obtained from different locations (cervix, fornix, outer vaginal canal) and by different methods (swabbing, scraping, lavaging) from the vaginal tracts of eight clinically healthy, asymptomatic women. The data reveal that the vaginal microbiota is not homogenous throughout the vaginal tract but differs significantly within an individual with regard to anatomical site and sampling method used. Thus, this study illuminates the complex structure of the vaginal ecosystem and calls for the consideration of microenvironments when sampling vaginal microbiota as a clinical predictor of vaginal health.

The modified massive cuff stitch: functional and structural outcome in massive cuff tears  

PubMed Central

Background The massive cuff stitch (MCS) is known to be a strong suture, suitable for rotator cuff repair. We modified this technique for massive cuff tears by employing a horizontal medial mattress suture from an anchor as well as a vertically crossing transosseous suture. Methods We included 42 patients with massive cuff tears suitable for repair: 22 were treated with the modified MCS (MCS group), and 20 with a simple transosseous suture (STS group). The range of motion (ROM), muscle strength, visual analog scale, and the Japanese Orthopaedic Association (JOA) scores were evaluated pre-operatively and 12 and 24 months post-operatively. The incidence of post-operative re-tears was examined at least 1 year post-operatively using Sugaya's classification. Results The ROM, muscle strength, degree of pain, and the JOA scores were much improved after surgery in both groups, and there was no significant intergroup difference throughout the pre- and post-operative periods. In contrast, post-operative MRI revealed a significantly lower re-tear rate in the MCS group than in the STS group (9.1% vs. 40%, P = 0.0296). Conclusions The techniques tested were comparable in terms of functional outcome after surgical repair of massive cuff tears; however, the modified MCS repair technique produced superior structural outcomes with a significantly lower re-tear rate.

Multicatheter Device for Brachytherapy Treatment  

NASA Astrophysics Data System (ADS)

Low dose rate brachytherapy treatment for prostate cancer encompasses the delivery of capsules containing radioactive material into the prostate's cancerous tissue via injection through needles. High dose rate brachytherapy treatment for prostate cancer follows the same concept with the difference that the radioactive source has a higher activity and it is placed temporarily into the patient. For this reason, the source is driven by an afterloading device that moves the source into the catheters and back into a shielded container. From both HDR and LDR brachytherapy, two issues remain unaddressed: homogeneity and localization. Sources not being homogeneous result in a delivered dose that does not correspond to the treatment plan. In the case of HDR, the afterloader not always places the source where it should within the catheter. This results in undertreatment of the cancerous tissue as well as damage to healthy tissue. To address both issues we have placed scintillating fiber into brachytherapy needles. If placed geometrically around the radioactive seeds we are able to check for homogeneity in the sources. At the same time, by analyzing the detected signals we are trying to determine the exact physical position of the seeds within the catheter. Using a radioactive source, we have taken measurements to calibrate the device and measurements under water to simulate living tissue environment. Results are discussed.

Vaginal oxytetracycline concentrations.

Although tetracycline preparations are widely used in departments of genitourinary medicine, or sexually transmitted diseases clinics, little is known of the concentrations of these preparations in genital secretions. For this reason a microbiological method was used for estimating oxytetracycline concentrations in vaginal secretions. These concentrations varied from 0.6 to 6.5 microgram/ml in 19 women who had had sexual contact with a man with non-specific urethritis and who were taking oxytetracycline dihydrate 250 mg four times daily. They were well in excess of the minimum inhibitory concentration of oxytetracycline (0.2 microgram/ml) for the strains of Chlamydia trachomatis isolated from the patients with positive culture results. Thus, oxytetracycline 250 mg four times daily appears to be a satisfactory regimen for the treatment of chlamydial genital infection in women. PMID:509190

Injuries of the musculotendinous cuff are frequent and often cause long periods of disability. The cuff is subject to progressive degenerative changes which are visible microscopically in most persons past 30 years of age, and visible grossly in those past 40. The cuff ruptures through areas of degeneration. A great majority of patients recover good shoulder function under conservative treatment. Operation is not urgent. Accurate diagnosis of a complete tear of the cuff cannot be made until the acute phase of injury has passed, and delay in operating does not decrease chances of good results.

Role of biomechanics in rotator cuff pathology: North American perspective.  

PubMed

The biomechanical properties of, and mechanical environment surrounding, the rotator cuff continue to be a research area of great interest as injury and failure of these tendons are among the most common of shoulder pathologies, with incidence increasing in older populations. Recent literature has refined our knowledge of the anatomy, the role of the various tendons in movement and shoulder stability, and structural and material properties of the human rotator cuff. Furthermore, animal models have characterized the effects of mechanical loading on rotator cuff properties, the biomechanical interactions among cuff tendons in uninjured and deficient rotator cuffs have been described, and more recent imaging studies have provided novel insights into the function of the rotator cuff in vivo. Research to advance our understanding of the biomechanical factors contributing to rotator cuff disease is needed, as the etiology, prognostic indicators, and reasons for treatment failure are poorly understood. We summarize published biomechanical literature on the rotator cuff to provide a current perspective on potential mechanisms involved in cuff pathology. PMID:21986042

Conservative treatment and rotator cuff tear progression.  

PubMed

There is no definite consensus on the best management for patients with rotator cuff tears. No randomized controlled studies have compared the outcome of surgical versus conservative treatment. The described successful rate of conservative treatment varies widely, from 33 to 92%. Even though current evidence is not sufficient to allow definitive conclusions on conservative treatment of rotator cuff tears, non-operative management is often recommended in such patients. Prognostic factors seem to be clinical presentation, duration of symptoms and tear size. The best programme for conservative treatment is not defined. Physical therapy consists of stretching and strengthening exercises. The characteristics of exercise programmes are not standardized. In clinical practice, intra-articular injections are commonly used for treatment of shoulder pain. Systemic pharmacotherapy for patients with shoulder pain consists of non-steroidal anti-inflammatory drugs. Recently, cyclo-oxygenase-2-selective inhibitors have been introduced for management of shoulder pain.

Biological Augmentation of Rotator Cuff Tendon Repair  

PubMed Central

A histologically normal insertion site does not regenerate following rotator cuff tendon-to-bone repair, which is likely due to abnormal or insufficient gene expression and/or cell differentiation at the repair site. Techniques to manipulate the biologic events following tendon repair may improve healing. We used a sheep infraspinatus repair model to evaluate the effect of osteoinductive growth factors and BMP-12 on tendon-to-bone healing. Magnetic resonance imaging and histology showed increased formation of new bone and fibrocartilage at the healing tendon attachment site in the treated animals, and biomechanical testing showed improved load-to-failure. Other techniques with potential to augment repair site biology include use of platelets isolated from autologous blood to deliver growth factors to a tendon repair site. Modalities that improve local vascularity, such as pulsed ultrasound, have the potential to augment rotator cuff healing. Important information about the biology of tendon healing can also be gained from studies of substances that inhibit healing, such as nicotine and antiinflammatory medications. Future approaches may include the use of stem cells and transcription factors to induce formation of the native tendon-bone insertion site after rotator cuff repair surgery.

Brachytherapy for advanced prostate cancer bleeding.  

PubMed

Advanced prostate cancer patients frequently deal with intractable prostatic bleeding which is a difficult problem to manage. Intraurethral high-dose rate (HDR) brachytherapy may palliate this condition. Advanced prostate cancer patients with intractable prostatic bleeding were offered brachytherapy with Iridium-192 using a Micro-selectron HDR machine. During a 5-year period, analysis was performed in 23 patients with a median age and Gleason score of 78 years and 9, respectively. Following brachytherapy, haematuria resolved in 19 of the 23 patients and was recurrence free at 6 months. Intraurethral HDR brachytherapy is a potentially effective modality for treating haematuria in patients with advanced prostate cancer. PMID:18391938

Desquamative inflammatory vaginitis. A review.  

PubMed Central

Desquamative inflammatory vaginitis is an uncommon cause of an intractable vaginitis often accompanied by serious dyspareunia, which can occur at any stage of reproductive life and after the menopause. The cytological changes are identical with those seen in atrophic vaginitis yet the disorder often occurs in the presence of apparently normal ovarian function. Vaginal synechiae and stenosis develop in an appreciable number of patients. Treatment is unsatisfactory though there is some response to either local or systemic steroid therapy. The literature is reviewed and the association of some cases with lichen planus of the mouth and genitals discussed. Its causation and natural history remain largely unknown and there is as yet, insufficient evidence to regard it as a single entity. It is likely that the incidence of the disorder is underestimated.

Arthroscopic repair techniques for massive rotator cuff tears.  

PubMed

Patients with massive rotator cuff tears present with pain, weakness, and loss of function. Candidates for arthroscopic repair include symptomatic, young, active patients; those with an acute tear or tears with early changes of atrophy; and patients willing to comply with recovery and rehabilitation processes after surgery. As massive rotator cuff tears extend, the glenohumeral articulation is destabilized, allowing superior migration. Repair of the force couples and reinforcement of the anterosuperior rotator cuff cable can restore functional elevation via the deltoid. Muscle changes, including rotator cuff atrophy and fatty infiltration, will affect shoulder strength and function. As chronic changes become more extensive (such as the absence of the acromiohumeral interval and degenerative joint changes), other repair options may be more durable. Other arthroscopic options, including partial rotator cuff closure, graft to augment the repair, and use of the long head of the biceps tendon, have been helpful in pain relief and functional gains.

Impact of vaginal ascorbic acid on abnormal vaginal microflora.  

PubMed

PURPOSE: To evaluate the impact of vaginal ascorbic acid (vitamin C) as a treatment/maintenance regimen on increased vaginal pH and abnormal microflora on wet mounts in premenopausal women. METHODS: A randomized study of 140 asymptomatic, low-risk pregnant and non-pregnant premenopausal women with vaginal pH ? 4.5 and a variety of partly/completely disrupted Lactobacillus microflora patterns on wet mounts in five outpatient clinics was carried out. Participants were randomized to the intervention group [250 mg vitamin C tablets vaginally at bedtime once a day for 6 days (treatment phase), followed by a one tablet per week, for 12 weeks (maintenance phase)] or the control group (no treatment). Outcomes were evaluated 4 months after randomizing, i.e., 2-3 weeks after the last vitamin C tablet insertion. RESULTS: Normalization to normal flora was observed in 51.4 % of all ascorbic acid and in 24.3 % of control group patients (difference 27.1 %, 95 % CI 11.7-42.6, p < 0.05, ITT population). In the per protocol population, normalization was confirmed in 53.5 % of the intervention and 22.4 % of the control group (difference 31 %, 95 % CI 14.3-47.8, p < 0.05). Results of pregnant subgroup analysis showed better outcomes for the subgroup: difference of normalization rate between ascorbic acid and control group was 41.2 % (95 % CI 21.8-60.1, p < 0.05). Itching occurred in 19 %; 23 % of women reported irritation and 10 % stopped the treatment because of side effects. CONCLUSIONS: Vaginal ascorbic acid improves abnormal vaginal pH and microflora, especially in pregnant women, but is not well tolerated by all women. PMID:23677418

[Multipurpose treatment of vaginal infections].

Untreated bacterial vaginosis is related with many complications for non-pregnant women in reproductive age, most common from them are vaginal discharge and postoperative infections. The aim of our investigation was to compare the effectiveness of two therapeutic regimes which consist in Macmiror/Macmiror Complex alone and in combination with Feminella Vagi C for treatment of bacterial vaginosis (BV) and/or mycotic infection. 117 non-pregnant women with symptoms of vaginal infection were prospectively enrolled into two groups according their treatment. First group consist 66 women treated with Macmiror tablets and vaginal capsules followed with local application of Feminella Vagi C, the second group consist 54 women treated with Macmiror tablets and vaginal capsules only. The impact of treatment on clinical symptoms was observed at the end of medication and 20 days after it. Microbiological testing was repeated 20 days after treatment. Over than 80% (78.6 divided by 86.7%) of the cases with vaginal infection (BV and mycotic one) were successfully treated with Macmiror/Macmiror Complex. Supplement treatment with Feminella Vagi C lead to higher percentage of clinically recovery (86.7% vs 84.6%), better microbiological cleaning (86.7% vs 82.1%) and longer effect of treatment. Used medication showed higher efficacy against BV than to fungal infection. According obtained results we may conclude that bacterial vaginosis was better treated with multipurpose treatment (Nifuratel, Nistatin and vit. C) than with Macmiror alone. PMID:23234030

Outcomes after arthroscopic rotator cuff repairs.  

PubMed

Recently, advances in arthroscopic techniques have allowed shoulder surgeons to perform fully arthroscopic repair of full-thickness tears. Outcome data have shown that improvement is inconsistent between studies. We performed a retrospective review of 105 consecutive patients who underwent arthroscopic rotator cuff repair from 1999 to 2002. Preoperative and postoperative evaluation consisted of a history, questionnaire, and examination to determine American Shoulder and Elbow Surgeons, Constant, and visual analog pain scores. Complete data were available for a minimum of 12 months (range, 12-45 months) for 71 patients. Increases in range of motion and outcome scores and associated reductions in visual analog scores were all significant. With massive tears, scores and pain were significantly improved. Arthroscopic rotator cuff repair reliably improves functional deficits and pain regardless of tear size. Smaller tears yield significant improvement in American Shoulder and Elbow Surgeons, Constant, and pain scores. Functional improvement was seen with massive tears, but gains in strength and motion were less dramatic. PMID:17011216

Xoft Axxent electronic brachytherapy: a new device for delivering brachytherapy to the breast.  

PubMed

Balloon-based brachytherapy was developed to simplify the brachytherapy technique and make accelerated partial breast irradiation more accessible to patients with breast cancer who are suitable candidates for this technique. Xoft Axxent (Xoft, Inc., Sunnyvale, CA) electronic brachytherapy is a novel method of accelerated partial breast irradiation that uses an electronic source to produce X-rays. Xoft Axxent treatment does not require a high-dose-rate afterloader unit or a shielded vault, unlike other brachytherapy techniques that use iridium-192, such as MammoSite brachytherapy. Xoft Axxent is associated with the delivery of less radiation to normal tissues, and increased high radiation dose regions or 'hot spots' to the target volume compared with treatment with the MammoSite device. Further research will be needed to determine subgroups of patients who might benefit from treatment with Xoft Axxent electronic brachytherapy. PMID:19174776

Use of electronic brachytherapy to deliver postsurgical adjuvant radiation therapy for endometrial cancer: a retrospective multicenter study  

PubMed Central

Background: This retrospective, multicenter study evaluated the feasibility and safety of high-dose rate electronic brachytherapy (EBT) as a postsurgical adjuvant radiation therapy for endometrial cancer. Methods: Medical records were reviewed from 41 patients (age 40–89 years) with endometrial cancer (Federation of International Gynecology and Obstetrics stages IA–IIIC) treated at nine centers between April 2008 and October 2009. Treatment included intracavitary vaginal EBT alone (n = l6) at doses of 18.0–24.0 Gy in 3–4 fractions and EBT in combination with external beam radiation therapy (EBRT, n = 25) at a total radiation dose range of 40.0–80.4 Gy. Doses were prescribed to a depth of 5 mm from the applicator surface and to the upper third (n = 15) and the upper half (n = 26) of the vagina. Results: Median follow-up was 3.8 (range 0.5–12.0) months. All 41 patients received the intended dose of radiation as prescribed. Adverse events occurred in 13 of 41 patients and were mild to moderate (Grade 1–2), consisting primarily of vaginal mucositis, rectal mucosal irritation and discomfort, and temporary dysuria and diarrhea. There were no Grade 3 adverse events in the EBT-only treatment group. One patient, who was being treated with the combination of EBT and EBRT for recurrent endometrial cancer, had a Grade 3 adverse event. No recurrences have been reported to date. Conclusion: Electronic brachytherapy provides a feasible treatment option for postoperative adjuvant vaginal brachytherapy as sole radiation therapy and in combination with EBRT for primary endometrial cancer. Early and late toxicities were mild to moderate.

Evaluation of cartilage degeneration in a rat model of rotator cuff tear arthropathy.  

PubMed

BACKGROUND AND HYPOTHESIS: Rotator cuff tears are the most common injury seen by shoulder surgeons. Glenohumeral osteoarthritis develops in many late-stage rotator cuff tear patients as a result of torn cuff tendons, termed "cuff tear arthropathy." However, the mechanisms of cuff tear arthropathy have not been fully established. It has been hypothesized that a combination of synovial and mechanical factors contribute equally to the development of cuff tear arthropathy. The goal of this study was to assess the utility of this model in investigating cuff tear arthropathy. MATERIALS AND METHODS: We used a rat model that accurately reflects rotator cuff muscle degradation after massive rotator cuff tears through either infraspinatus and supraspinatus tenotomy or suprascapular nerve transection. Using a modified Mankin scoring system, we found significant glenohumeral cartilage damage after both rotator cuff tenotomy and suprascapular nerve transection after only 12 weeks. RESULTS: Cartilage degeneration was similar between groups and was present on both the humeral head and the glenoid. Denervation of the supraspinatus and infraspinatus muscles without opening the joint capsule caused cartilage degeneration similar to that found in the tendon transection group. CONCLUSIONS: Our results suggest that altered mechanical loading after rotator cuff tears is the primary factor in cartilage degeneration after rotator cuff tears. Clinically, understanding the process of cartilage degeneration after rotator cuff injury will help guide treatment decisions in the setting of rotator cuff tears. PMID:23664745

Massive Rotator Cuff Tear in an Adolescent Athlete  

PubMed Central

Full-thickness rotator cuff tears in the young athlete are a rare injury. These injuries typically result from an acute traumatic event in a contact athlete, as opposed to overuse injuries more commonly seen in throwing athletes. Acute tears may be initially overlooked, with the symptoms attributed to other, more common causes, such as cuff contusion or brachial plexus neuropraxia (“stinger” or “burner”). If undiagnosed, the tear may progress to an irreparable state at the time of eventual diagnosis. Therefore, rotator cuff tear must be included in the differential for acute shoulder injuries in the young athlete. This article presents a case of an adolescent athlete with a traumatic, massive rotator cuff tear that was diagnosed and managed promptly with excellent outcome.

The role of the endotracheal tube cuff in microaspiration.  

PubMed

The cuff of the endotracheal tube (ETT) is designed to provide a seal within the airway, allowing airflow through the ETT but preventing passage of air or fluids around the ETT. Deliberate or inadvertent movement of the ETT may affect cuff pressure or shift folds in the cuff, mobilizing pooled secretions. When this seal is compromised, microaspirations contaminated with gastric contents or bacterially colonized oral secretions can occur that leave the patient susceptible to a host of problems, such as hypoxia, pneumonitis, and respiratory infections. These complications are costly in terms of morbidity and mortality, as well as hospital expense. We will discuss the role of the ETT cuff in microaspiration and identify potential directions for future research to improve outcomes in mechanically ventilated patients. PMID:22209048

Endotracheal tube cuff pressure monitoring: a review of the evidence.  

PubMed

Tracheal intubation constitutes a routine part of anaesthetic practice both in the operating theatre as well as in the care of critically ill patients. The procedure is estimated to be performed 13-20 million times annually in the United States alone. There has been a recent renewal of interest in the morbidity associated with endotracheal tube cuff overinflation, particularly regarding the rationale and requirement for endotracheal tube cuff monitoring intra-operatively.

Endotracheal tube cuff leak with mysterious laryngotracheal pathology.  

PubMed

A 63 year-old obese man with gastroesophageal reflux disease, hiatal hernia, and no known history of airway pathology was to undergo a total knee arthroplasty. After intubation, however, repeated cuff leaks, decreasing tidal volumes, and desaturations prompted five additional endotracheal tube placements. Findings on radiography, computed tomography, and fiberoptic laryngoscopy and tracheoscopy were equivocal. Factors contributing to this challenge of persistent and repeated cuff leaks in the absence of known airway pathology could include various laryngotracheal abnormalities. PMID:23634577

Mechanics of the occlusive arm cuff and its application as a volume sensor.  

PubMed

Although a common medical instrument, the mechanical function of an occlusive arm cuff has not been fully described in an engineering sense. The occlusive arm cuff is examined here using a mathematical mechanics model and experimental measurements. Cuff stretch was modeled by a nonlinear pressure-volume function. Air compression was represented by Boyle's law. An apparatus was developed to measure pressure due to the air volume pumped into the cuff for fixed arm volume. Data were obtained for two different cuff designs, and reveal a nonlinear cuff pressure-volume relationship that could be represented accurately by the mathematical model. Calibration constants are provided for the two types of occlusive cuff. Thus, the cuff pressure was found to consist of a balance between that produced by stretch of the elastic cuff bladder and that of the compression of the air contained within the bladder. The use of the gas law alone was found to be inadequate to represent the cuff mechanics. When applying the cuff to measure change in arm volume, such as during plethysmography or oscillometry, it cannot be assumed that the cuff sensitivity is constant. More precisely, it was found that the occlusive cuff is a transducer with a volume sensitivity that increases with cuff pressure and volume until it becomes nearly constant at high levels of cuff pressure (150 mmHg). A hypothetical case of a linear elastic artery with constant pulse pressure was used as input to the cuff model to illustrate the change in cuff pressure oscillations that occurs while cuff pressure is released.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:8244431

Suprascapular Nerve: Is It Important in Cuff Pathology?  

PubMed Central

Suprascapular nerve and rotator cuff function are intimately connected. The incidence of suprascapular neuropathy has been increasing due to improved understanding of the disease entity and detection methods. The nerve dysfunction often results from a traction injury or compression, and a common cause is increased tension on the nerve from retracted rotator cuff tears. Suprascapular neuropathy should be considered as a diagnosis if patients exhibit posterosuperior shoulder pain, atrophy or weakness of supraspinatus and infraspinatus without rotator cuff tear, or massive rotator cuff with retraction. Magnetic resonance imaging and electromyography studies are indicated to evaluate the rotator cuff and function of the nerve. Fluoroscopically guided injections to the suprascapular notch can also be considered as a diagnostic option. Nonoperative treatment of suprascapular neuropathy can be successful, but in the recent decade there is increasing evidence espousing the success of surgical treatment, in particular arthroscopic suprascapular nerve decompression. There is often reliable improvement in shoulder pain, but muscle atrophy recovery is less predictable. More clinical data are needed to determine the role of rotator cuff repair and nerve decompression in the same setting.

Primary Vaginal Cancer Treated With Concurrent Chemoradiation Using Cis-Platinum  

SciTech Connect

Purpose: To evaluate the feasibility of concurrent weekly Cis-platinum chemoradiation (CRT) in the curative treatment of primary vaginal cancer. Methods: A retrospective review was performed of all primary vaginal cancer patients treated with curative intent at the Ottawa Hospital Regional Cancer Centre between 1999 and 2004 using concurrent Cis-platinum CRT. Results: Twelve patients were treated with concurrent weekly CRT. The median age at diagnosis was 56 years (range, 34-69 years), and the median follow-up was 50 months (range, 11-75 months). Ten patients (83%) were diagnosed with squamous cell carcinoma and 2 patients (17%) with adenocarcinoma. The distribution according to stage was as follows: 6 (50%) Stage II, 4 (33%) Stage III, and 2 (17%) Stage IVA. All patients received pelvic external beam radiotherapy (EBRT) concurrently with weekly intravenous Cis-platinum chemotherapy (40 mg/m{sup 2}) followed by brachytherapy (BT). The median dose of EBRT was 4500 cGy given in 25 fractions over 5 weeks. Ten patients received interstitial BT, and 2 patients received intracavitary BT, with the median dose being 3000 cGy. The 5-year overall survival, progression-free survival, and locoregional progression-free survival rates were 66%, 75%, and 92%, respectively. Late toxicity requiring surgery occurred in 2 patients (17%). Conclusions: For the treatment of primary vaginal cancer, it is feasible to deliver concurrent weekly Cis-platinum chemotherapy with high-dose radiation, leading to excellent local control and an acceptable toxicity profile.

Is sealing cuff pressure, easy, reliable and safe technique for endotracheal tube cuff inflation?: A comparative study  

PubMed Central

Objective: To compare the three common methods of endotracheal tube cuff inflation (sealing pressure, precise standard pressure or finger estimation) regarding the effective tracheal seal and the incidence of post-intubation airway complications. Methods: Seventy-five adult patients scheduled for N2 O free general anesthesia were enrolled in this study. After induction of anesthesia, endotracheal tubes size 7.5 mm for female and 8.0 mm for male were used. Patients were randomly assigned into one of three groups. Control group (n=25), the cuff was inflated to a pressure of 25 cm H2O; sealing group (n=25), the cuff was inflated to prevent air leaks at airway pressure of 20 cm H2O and finger group (n=25), the cuff was inflated using finger estimation. Tracheal leaks, incidence of sore throat, hoarseness and dysphagia were tested. Results: Although cuff pressure was significantly low in the sealing group compared to the control group (P<0.001), the incidence of sore throat was similar in both groups. On the other hand, cuff pressure as well as the incidence of sore throat were significantly higher in the finger group compared to both the control and the sealing group (P<0.001 and P=0.008). The incidence of dysphagia and hoarseness were similar in the three groups. None of the patients in the three groups developed air leak around the endotracheal tube cuff.. Conclusions: In N2O, free anesthesia sealing cuff pressure is an easy, undemanding and safe alternative to the standard technique, regarding effective sealing and low incidence of sore throat.

Antigonococcal effects of vaginal tampons.  

PubMed Central

Different brands of vaginal tampons varied significantly (p less than 0.0001) in their anti-bacterial effects when tested with 46 strains of Neisseria gonorrhoeae. Gonococcal strains recovered from patients with disseminated infections were substantially more sensitive to the anti-bacterial effects of tampons than were strains from patients with uncomplicated genital infections. Strains from patients with pelvic inflammatory disease were moderately sensitive. Tampons showing strong in-vitro antigonococcal effects were also generally effective in vivo in eliminating gonococcal infections from subcutaneous chambers in mice. Extracts of the Rely tampon showed no in-vitro antigonococcal effect, however, but did induce antibacterial activity when injected into subcutaneous chambers in mice. These results emphasise the importance of both in-vitro as well as in-vivo testing of tampon materials to elucidate more fully the nature of their antibacterial effects and their potential for affecting vaginal pathogens and disease processes.

This article reviews in detail the indications, contraindications, patient selection criteria, choice of instrument, and technique for vacuum-assisted vaginal delivery. The use of vacuum extraction at the time of cesarean delivery will also be discussed. With vacuum extraction becoming increasingly popular, it is important that obstetric care providers are aware of the maternal and neonatal risks associated with such deliveries and of the options available to effect a safe and expedient delivery.

A simple method of partial inflation of the LMA cuff before insertion in children to allow cuff pressure without adjustment after insertion  

PubMed Central

Background The cuff of the laryngeal mask airway (LMA) is preferred to be partially inflated before insertion in pediatric cases. However, it is not known how much inflation is appropriate. In addition, intra-cuff pressure is not routinely monitored in many institutions despite the fact that a neglected high cuff pressure could cause several complications. This study was conducted to determine whether the cuff inflated with its resting volume before insertion could have a clinically tolerable intra-cuff pressure after insertion. Methods One hundred fifty unpremedicated children aged 0 to 9 yrs were enrolled. The pilot balloon valve was connected to a piston-free syringe to keep the valve open to the atmosphere and allowing the pressure within the cuff of to LMA to equalize to atmospheric pressure. Anesthesia was induced with 6 vol% of sevoflurane in oxygen. After insertion and final positioning of the LMA, the intra-cuff pressure was measured using a cuff pressure manometer. Results The mean intra-cuff pressure was 50 ± 12.9 cmH2O; intra-cuff pressures were 39.1 ± 9.3, 51.6 ± 11.2, and 64.6 ± 12.5 cmH2O for LMAs of sizes 1.5, 2, and 2.5, respectively. Intra-cuff pressure of more than 60 cmH2O was measured in 26 patients, and the median value was 70 cmH2O. There was weak statistical correlation among age, height, and weight with intra-cuff pressure. Conclusions The cuff inflated by the resting volume before insertion may be a simple method for guaranteeing tolerable cuff pressure after insertion.

Dosimetric Characteristics for Brachytherapy Sources  

NASA Astrophysics Data System (ADS)

Brachytherapy sources are characterized by the dosimetric parameters in a protocol such as the American Association of Physicists in Medicine Task Group 43. The air-kerma strength is measured and traceable to a primary standard. Then the parameters such as dose-rate constant, radial dose function, and anisotropy function are measured and related back to the primary standard. This is normally accomplished with thermoluminescent dosimeters (TLDs). Since radial dose function and anisotropy function are relative parameters, some of the dosimetric corrections are negligible. For the dose-rate constant, parameters such as the energy dependence compared with a calibration beam such as 60Co need to be accounted for. A description of the primary standard measurements and TLD measurements will be discussed.

The vaginal microbiome: rethinking health and diseases  

PubMed Central

Vaginal microbiota form a mutually beneficial relationship with their host and have major impact on health and disease. In recent years our understanding of vaginal bacterial community composition and structure has significantly broadened as a result of investigators using cultivation-independent methods based on the analysis of 16S ribosomal RNA (rRNA) gene sequences. In asymptomatic, otherwise healthy women, several kinds of vaginal microbiota exist, the majority often dominated by species of Lactobacillus, while others comprise a diverse array of anaerobic microorganisms. Bacterial vaginosis is the most common vaginal conditions and is vaguely characterized as the disruption of the equilibrium of the ‘normal’ vaginal microbiots. A better understanding of ‘normal’ and ‘healthy’ vaginal ecosystems that is based on its ‘true’ function and not simply on its composition would help better define health and further improve disease diagnostics as well as the development of more personalized regimens to promote health and treat diseases.

Purpose: To evaluate the efficacy of {sup 106}Ru plaque brachytherapy for the treatment of retinoblastoma. Methods and Materials: We reviewed a retrospective, noncomparative case series of 39 children with retinoblastoma treated with {sup 106}Ru plaques at the Jules-Gonin Eye Hospital between October 1992 and July 2006, with 12 months of follow-up. Results: A total of 63 tumors were treated with {sup 106}Ru brachytherapy in 41 eyes. The median patient age was 27 months. {sup 106}Ru brachytherapy was the first-line treatment for 3 tumors (4.8%), second-line treatment for 13 (20.6%), and salvage treatment for 47 tumors (74.6%) resistant to other treatment modalities. Overall tumor control was achieved in 73% at 1 year. Tumor recurrence at 12 months was observed in 2 (12.5%) of 16 tumors for which {sup 106}Ru brachytherapy was used as the first- or second-line treatment and in 15 (31.9%) of 47 tumors for which {sup 106}Ru brachytherapy was used as salvage treatment. Eye retention was achieved in 76% of cases (31 of 41 eyes). Univariate and multivariate analyses revealed no statistically significant risk factors for tumor recurrence. Radiation complications included retinal detachment in 7 (17.1%), proliferative retinopathy in 1 (2.4%), and subcapsular cataract in 4 (9.7%) of 41 eyes. Conclusion: {sup 106}Ru brachytherapy is an effective treatment for retinoblastoma, with few secondary complications. Local vitreous seeding can be successfully treated with {sup 106}Ru brachytherapy.

Experimental study on rotator cuff repair.  

PubMed

It was the purpose of the experimental study to use laboratory experience to verify the effectiveness of different methods used to repair the rotator cuff. The sheep was used as an animal model because its infraspinous tendon is the most similar to that in the human. Three static trials were conducted using Instron machines, comparing the repair systems used most by the same authors in their clinical work, the hold of the suturing wires with two different threading procedures in the bone tunnels and two types of knotting, and the breakage loading of the suturing wires in the two different miniplate systems. The authors conclude that tendinous anchoring must be entrusted to reinforced suturing systems (modified SCOI and Mason Allen), the threading of wires in pairs in a single bone tunnel makes surgery easier and shortens the amount of time required, with threading of wires similar to or better than threading with a single wire. There are no differences in breakage loading of the wire at the level of the holes in the two miniplates considered in this study. PMID:12056246

Subdeltoid lipoma arborescens combined with rotator cuff tears.  

PubMed

Lipoma arborescens, a rare benign intra-articular lesion, is characterized by lipomatous proliferation of the synovium in which the subsynovial tissue is replaced by mature adipocytes. Subdeltoid bursa is a rare location for lipoma arborescens, and only a few cases have been reported in the literature. This article reports 2 cases of subdeltoid lipoma arborescens combined with rotator cuff tears, and the possible relationships between subdeltoid lipoma arborescens and rotator cuff tears are discussed. The intra-articular villous proliferations on fat-suppressed T2-weighted magnetic resonance imaging appeared as yellowish-white lipomatous villous proliferations on arthroscopy, and finger-like lipomatous proliferation of the synovium, where the subsynovial connective tissue is replaced by mature adipocytes, on histology. Although further evidence would be necessary, the bony proliferations, in addition to bone-to-bone abrasion and inflammatory processes, may contribute to the relationship between subdeltoid lipoma arborescens and rotator cuff tears. Because this is a rare disease in a rare location, no established treatment guidelines are available for lipoma arborescens in subdeltoid bursa. For the current patients, arthroscopic excision of the lipoma arborescens and concomitant rotator cuff repair were prescribed after more than 6 months of conservative management. All patients had symptom relief and were satisfied with their results. Paying special attention to the radiologic and arthroscopic characteristics of the lipoma arborescens will help physicians and surgeons to achieve a more accurate diagnosis and effective treatment strategy, especially in patients with concomitant rotator cuff tears.

The incidence of rotator cuff tear increases with age. Degenerative rotator cuff tears are commonly seen in athletes above 40 years. These athletes are commonly involved in overhead activities. Repetitive microtrauma is a more important factor in rotator cuff degeneration than acute trauma. Conservative treatment is the mainstay treatment for these injuries.

Brachytherapy for Prostate Cancer: A Systematic Review  

PubMed Central

Low-dose rate brachytherapy has become a mainstream treatment option for men diagnosed with prostate cancer because of excellent long-term treatment outcomes in low-, intermediate-, and high-risk patients. To a great extend due to patient lead advocacy for minimally invasive treatment options, high-quality prostate implants have become widely available in the US, Europe, and Japan. High-dose-rate (HDR) afterloading brachytherapy in the management of localised prostate cancer has practical, physical, and biological advantages over low-dose-rate seed brachytherapy. There are no free live sources used, no risk of source loss, and since the implant is a temporary procedure following discharge no issues with regard to radioprotection use of existing facilities exist. Patients with localized prostate cancer may benefit from high-dose-rate brachytherapy, which may be used alone in certain circumstances or in combination with external-beam radiotherapy in other settings. The purpose of this paper is to present the essentials of brachytherapies techniques along with the most important studies that support their effectiveness in the treatment of prostate cancer.

Glycosaminoglycans of human rotator cuff tendons: changes with age and in chronic rotator cuff tendinitis.  

PubMed Central

OBJECTIVES--To analyse the glycosaminoglycans of the adult human rotator cuff tendon matrix, to characterise changes in the glycosaminoglycan composition with age and in chronic rotator cuff tendinitis. METHODS--Rotator cuff (supraspinatus) tendons (n = 84) and common biceps tendons (n = 26) were obtained from cadavers with no history of tendon pathology (age range 11-95 years). Biopsies of rotator cuff tendons (supraspinatus and subscapularis tendons, n = 53) were obtained during open shoulder surgery to repair shoulder lesions (age range 38-80 years). Glycosaminoglycans were extracted by papain digestion and analysed by cellulose acetate electrophoresis, the carbazole assay for uronic acid and the dimethylmethylene blue dye-binding assay for sulphated glycosaminoglycans. Some digests were analysed for keratan sulphate by 5D4 monoclonal antibody ELISA. Soluble proteoglycans were extracted in 4M guanidine hydrochloride and analysed by 4-15% SDS PAGE. RESULTS--The mean (SD) sulphated glycosaminoglycan (GAG) content of the normal cadaver supraspinatus tendon was 12.3 (4.3) micrograms/mg dry weight, between three and ten times greater than in the common biceps tendon [1.2 (0.6) micrograms/mg dry weight]. The major GAG was chondroitin sulphate [6.9 (2.6) micrograms/mg dry weight], with a smaller proportion of dermatan sulphate [2.5 (1.2) micrograms/mg dry weight]. In contrast, the common biceps tendon contained predominantly dermatan sulphate [0.8 (0.2) microgram/mg dry weight] with less chondroitin sulphate [0.2 (0.2) microgram/mg dry weight]. There was no difference in the concentration of hyaluronan in these tendons [9.3 (2.8) micrograms/mg dry weight and 10.8 (4.3) micrograms/mg dry weight respectively] and there was no significant change of hyaluronan with age. Keratan sulphate was a small but significant component of the supraspinatus tendon [0.43 (0.33) microgram/mg dry weight, n = 25], whereas there was little or none in the common biceps tendon [0.04 (0.05) microgram/mg dry weight, n = 8] and there was no significant change across the age range. In the supraspinatus tendon, there was a significant decrease in total glycosaminoglycan, chondroitin sulphate and dermatan sulphate with age (p < 0.001), whether expressed relative to the tendon dry weight or total collagen content, and no change in the relative proportion of the different GAG types. There was, however, a large degree of variation within the samples. Supraspinatus tendons from patients with chronic tendinitis had a significantly increased concentration of hyaluronan [30.4 (10.1) micrograms/mg dry weight, p < 0.001], chondroitin sulphate [8.4 (1.8) micrograms/mg dry weight, p < 0.05] and dermatan sulphate [3.8 (1.1) micrograms/mg dry weight, p < 0.001] compared with normal cadaver supraspinatus tendons, although the keratan sulphate content was not significantly different [0.18 (0.05) microgram/mg dry weight]. CONCLUSIONS--The normal supraspinatus tendon has the proteoglycan/glycosaminoglycan of tendon fibrocartilage, which it is suggested is an adaptation to mechanical forces (tension, compression and shear) which act on the rotator cuff tendons in the shoulder, although other factors such as reduced vascularity, low oxygen tension and the influence of local growth factors may also be important. This functional adaptation may have important consequences for the structural strength of the supraspinatus tendon and to influence the ability of the tendon to repair after injury. The glycosaminoglycan composition of tendon specimens from patients with chronic tendinitis is consistent with acute inflammation and new matrix proteoglycan synthesis, even in relatively old tendon specimens and after at least one injection of corticosteroid.

Outcomes of term vaginal breech delivery.  

PubMed

In December 2001, the American College of Obstetricians and Gynecologists revised their recommendations for breech delivery. These recommendations acknowledge that although a planned vaginal delivery may no longer be appropriate, there are instances in which vaginal breech delivery is inevitable. Moreover, there continues to be patients who for any number of reasons will choose vaginal over cesarean delivery when faced with a fetus in the breech presentation. We sought to review maternal and fetal outcomes in such circumstances when vaginal breech delivery occurs, and compare these outcomes to elective cesarean deliveries for breech presentation. We performed a retrospective review of all singleton breech deliveries at our county hospital from January 2002 through June 2003. We reviewed maternal age, ethnicity, gestational age, gravity, parity, birthweight, mode of delivery, Apgar scores, umbilical arterial blood gases, and maternal and infant complications of both cesarean deliveries and vaginal breech deliveries. Univariate and logistic regression statistical analyses were performed with NCSS software. We had a total of 150 term breech deliveries with gestational ages between 37 and 42 weeks. Of these, 41 were vaginal breech and 109 were cesarean deliveries. Greater than 95% of patients are of Hispanic origin. There were no statistically significant differences in maternal age, ethnicity, gravity, or gestational age. Mean birthweight was significantly lower and parity was significantly higher in the vaginal delivery group. There was also a higher proportion of patients who underwent labor induction/augmentation in the vaginal group. We found no differences in the outcomes of 5-minute Apgar scores, umbilical arterial blood gas values, neonatal intensive care unit admissions, deaths or maternal/fetal complications reported between the two groups. Mean umbilical arterial blood gas values were greater than 7.18 in both groups. Vaginal breech delivery cannot always be avoided. Moreover, at our county hospital several patients continue to choose vaginal breech delivery. Our data would suggest that vaginal breech delivery remains a viable option in selected patients.

Development of Fatty Atrophy After Neurologic and Rotator Cuff Injuries in an Animal Model of Rotator Cuff Pathology  

PubMed Central

Background: Detachment of a tendon from its osseous insertion, as can be the case with severe rotator cuff injuries, leads to atrophy of and increased fat in the corresponding muscle. We sought to validate a rotator cuff injury model in the rabbit and to test the hypothesis that tenotomy of a rotator cuff tendon would consistently create muscle atrophy and fatty degeneration analogous to the changes that occur after injury to a nerve innervating the same muscle. Methods: New Zealand white rabbits were divided into three groups: (1) partial rotator cuff tear without retraction of the muscle, (2) complete rotator cuff tear with retraction of the muscle, and (3) nerve transection of the subscapular nerve. Animals were killed at two or six weeks after injury, and the muscles were analyzed for weight, cross-sectional area, myosin fiber-type composition, and fat content. In addition, the subscapular nerve was harvested at two weeks and evaluated for neuronal injury. Results: At six weeks after injury, the rabbit muscles in the complete tenotomy and nerve transection groups had significant decreases in wet mass and increases in fat content relative to the control groups. Fat accumulation had a similar spatial pattern at six weeks in both the nerve transection and complete tenotomy groups. Such changes were not seen in the partial tenotomy group. No change was found in muscle myosin fiber-type composition. At two weeks after injury, subscapular nerves in the complete tenotomy group showed gross evidence of neuronal injury. Conclusions: This study establishes the rabbit subscapularis muscle as a valid model to study the muscular changes associated with rotator cuff tears. Our data suggest that the muscular changes associated with complete tenotomy are comparable with those seen with denervation of the muscle and suggest that chronic rotator cuff tears may induce a neurologic injury. Clinical Relevance: Chronic rotator cuff injuries are associated with neuronal injury of the affected muscle. As such, neuronal injury may explain the histopathologic changes that have been observed following chronic rotator cuff tears.

Vaginitis: Its Diagnosis and Treatment  

PubMed Central

Ninety-nine patients with a variety of specific and non-specific vaginitis were treated initially with a broad spectrum anti-microbial agent (AVC cream) in an effort to alleviate the acute symptoms of these problems even before specific organisms could be isolated. Diagnostic methods are discussed for Candida albicans and trichomonas vaginalis which could be employed in routine office practice. This agents advantage in being effective against almost all known pathogens, is offset by its some-what limited effectiveness against trichomoniasis. It has been shown in this study to be well tolerated, and it offers an overall cure rate of 66 percent against the more common pathogens.

Normal isometric strength of rotator cuff muscles in adults  

PubMed Central

Objectives The most prevalent disorders of the shoulder are related to the muscles of rotator cuff. In order to develop a mechanical method for the evaluation of the rotator cuff muscles, we created a database of isometric force generation by the rotator cuff muscles in normal adult population. We hypothesised the existence of variations according to age, gender and dominancy of limb. Methods A total of 400 healthy adult volunteers were tested, classified into groups of 50 men and women for each decade of life. Maximal isometric force was measured at standardised positions for supraspinatus, infraspinatus and subscapularis muscles in both shoulders in every person. Torque of the force was calculated and normalised to lean body mass. The profiles of mean torque-time curves for each age and gender group were compared. Results Our data showed that men gradually gained maximal strength in the fifth decade, and showed decreased strength in the sixth. In women the maximal strength was gained in the fourth decade with gradual decline to the sixth decade of life. The dominant arm was stronger in most of the tested groups. The torque profiles of the rotator cuff muscles in men at all ages were significantly higher than that in women. Conclusions We found previously unrecognised variations of rotator cuff muscles’ isometric strength according to age, gender and dominancy in a normal population. The presented data may serve as a basis for the future studies for identification of the abnormal patterns of muscle isometric strength in patients with pathology of the rotator cuff muscles.

Rotator Cuff Tear Pain and Tear Size and Scapulohumeral Rhythm  

PubMed Central

Context: The body of knowledge concerning shoulder kinematics in patients with rotator cuff tears is increasing. However, the level of understanding regarding how pain and tear size affect these kinematic patterns is minimal. Objective: To identify relationships between pain associated with a full-thickness rotator cuff tear, tear size, and scapulohumeral rhythm (SHR) and to determine whether pain and tear size serve as predictors of SHR. Design: A test-retest design was used to quantify pain and SHR before and after a subacromial lidocaine injection. Correlation and multivariate analyses were used to identify relationships among pain, tear size, and SHR. Setting: Orthopaedic biomechanics research laboratory. Patients or Other Participants: Fifteen patients (age range, 40–75 years) with diagnosed full-thickness rotator cuff tears participated. They were experiencing pain at the time of testing. Intervention(s): Shoulder kinematic data were collected with an electromagnetic tracking system before and after the patient received a lidocaine injection. Main Outcome Measure(s): Pain was rated using a visual analog scale. Three-dimensional scapular kinematics and glenohumeral elevation were assessed. Scapular kinematics included anterior-posterior tilt, medial-lateral tilt, and upward-downward rotation. A regression model was used to calculate SHR (scapular kinematics to glenohumeral elevation) for phases of humeral elevation and lowering. Results: Linear relationships were identified between initial pain scores and SHR and between tear size and SHR, representing an increased reliance on scapular motion with increasing pain and tear size. Pain was identified as an independent predictor of SHR, whereas significant findings for the effect of tear size on SHR and the interaction between pain and tear size were limited. Conclusions: We noted an increased reliance on scapular contributions to overall humeral elevation with increasing levels of pain and rotator cuff tear size. Pain associated with a rotator cuff tear serves as a primary contributor to the kinematic patterns exhibited in patients with rotator cuff tears.

Perivascular fluid cuffs decrease lung compliance by increasing tissue resistance  

PubMed Central

Objective Lung inflammation causes perivascular fluid cuffs to form around extra-alveolar blood vessels; however, the physiologic consequences of such cuffs remain poorly understood. Herein, we tested the hypothesis that perivascular fluid cuffs, without concomitant alveolar edema, are sufficient to decrease lung compliance. Design Prospective, randomized, controlled study. Setting Research laboratory. Subjects One hundred twenty male CD40 rats. Interventions To test this hypothesis, the plant alkaloid thapsigargin was used to activate store-operated calcium entry and increase cytosolic calcium in endothelium. Thapsigargin was infused into a central venous catheter of intact, sedated, and mechanically ventilated rats. Measurements Static and dynamic lung mechanics and hemodynamics were measured continuously. Main Results Thapsigargin produced perivascular fluid cuffs along extra-alveolar vessels but did not cause alveolar flooding or blood gas abnormalities. Lung compliance dose-dependently decreased after thapsigargin infusion, attributable to an increase in tissue resistance that was attributed to increased tissue damping and tissue elastance. Airway resistance was not changed. Neither central venous pressure nor left ventricular end diastolic pressure was altered by thapsigargin. Heart rate did not change, although thapsigargin decreased pressure over time sufficient to reduce cardiac output by 50%. Infusion of the type 4 phosphodiesterase inhibitor, rolipram, prevented thapsigargin from inducing perivascular cuffs and decreasing lung compliance. Rolipram also normalized pressure over time and corrected the deficit in cardiac output. Conclusions Our findings resolve for the first time that perivascular cuff formation negatively impacts mechanical coupling between the bronchovascular bundle and the lung parenchyma, decreasing lung compliance without impacting central venous pressure.

External Pelvic and Vaginal Irradiation Versus Vaginal Irradiation Alone as Postoperative Therapy in Medium-Risk Endometrial Carcinoma-A Prospective Randomized Study  

SciTech Connect

Purpose: To evaluate the value of adjuvant external beam pelvic radiotherapy as adjunct to vaginal brachytherapy (VBT) in medium-risk endometrial carcinoma, with regard to locoregional tumor control, recurrences, survival, and toxicity. Methods and Materials: Consecutive series of 527 evaluable patients were included in this randomized trial. Median follow-up for patients alive was 62 months. The primary study endpoints were locoregional recurrences and overall survival. Secondary endpoints were recurrence-free survival, recurrence-free interval, cancer-specific survival, and toxicity. Results: Five-year locoregional relapse rates were 1.5% after external beam radiotherapy (EBRT) plus VBT and 5% after vaginal irradiation alone (p = 0.013), and 5-year overall survival rates were 89% and 90%, respectively (p = 0.548). Endometrial cancer-related death rates were 3.8% after EBRT plus VBT and 6.8% after VBT (p = 0.118). Pelvic recurrences (exclusively vaginal recurrence) were reduced by 93% by the addition of EBRT to VBT. Deep myometrial infiltration was a significant prognostic factor in this medium-risk group of endometrioid carcinomas but not International Federation of Gynecology and Obstetrics grade or DNA ploidy. Combined radiotherapy was well tolerated, with serious (Grade 3) late side effects of less than 2%. However, there was a significant difference in favor of VBT alone. Conclusions: Despite a significant locoregional control benefit with combined radiotherapy, no survival improvement was recorded, but increased late toxicity was noted in the intestine, bladder, and vagina. Combined RT should probably be reserved for high-risk cases with two or more high-risk factors. VBT alone should be the adjuvant treatment option for purely medium-risk cases.

Impact of point A asymmetry on local control and survival for low dose-rate (LDR) brachytherapy in cervical cancer  

PubMed Central

Purpose To evaluate whether Point A asymmetry in low dose-rate (LDR) brachytherapy is associated with local control (LC), disease-free survival (DFS) and/or overall survival (OS). Material and methods A retrospective analysis of disease control and survival outcomes was conducted for patients who underwent LDR brachytherapy for advanced cervical cancer. Institutional protocol entailed concurrent chemotherapy and whole pelvis radiotherapy (WPRT) over 5 weeks, followed by placement of Fletcher-Suit tandem and colpostat applicators at weeks 6 and 8. Objective Point A doses, 80-85 Gy, were accomplished by placement of Cesium-137 (Cs-137) sources. Cox proportional hazards regression models were used to assess associations between disease control and survival endpoints with variables of interest. Results The records of 50 patients with FIGO stage IB1-IVA cervical cancer undergoing LDR brachytherapy at our institution were identified. Thirty of these patients had asymmetry > 2.5%, and 11 patients had asymmetry > 5%. At a median survivor follow-up of 20.25 months, 15 patients had experienced disease failure (including 5 cervical/vaginal apex only failures and 2 failures encompassing the local site). Right/left dose asymmetry at Point A was associated with statistically significantly inferior LC (p = 0.035) and inferior DFS (p = 0.011) for patients with mean Point A dose of > 80 Gy. Insufficient evidence existed to conclude an association with OS. Conclusions LDR brachytherapy may be associated with clinically significant dose asymmetry. The present study demonstrates that patients with Point A asymmetry have a higher risk of failure for DFS and LC.

Metal markers for radiographic visualization of rotator cuff margins: A new technique for radiographic assessment of cuff repair integrity  

PubMed Central

Surgically repaired rotator cuff repairs may re-tear in the post-operative follow-up phase, and periodic imaging is useful for early detection. The authors describe a simple surgical technique that provides a visible clue to the tendon edge on an anteroposterior radiograph of the shoulder. The technique involves arthroscopic or mini-open radio-opaque tagging of the tendon edge using a metal marker, and followed by a double-row rotator cuff repair using suture anchors. Serial post-operative radiographs may then be used to monitor the position of the marker. Progressive or marked displacement of the marker suggests a failure of cuff repair integrity and should be evaluated further.

Protection against rat vaginal candidiasis by adoptive transfer of vaginal B lymphocytes.  

PubMed

Vulvovaginal candidiasis is a mucosal infection affecting many women, but the immune mechanisms operating against Candida albicans at the mucosal level remain unknown. A rat model was employed to further characterize the contribution of B and T cells to anti-Candida vaginal protection. Particularly, the protective role of vaginal B cells was studied by means of adoptive transfer of vaginal CD3(-) CD5(+) IgM(+) cells from Candida-immunized rats to naïve animals. This passive transfer of B cells resulted into a number of vaginal C. albicans CFU approximately 50% lower than their controls. Sorted CD3(-) CD5(+) IgM(+) vaginal B lymphocytes from Candida-infected rats proliferated in response to stimulation with an immunodominant mannoprotein (MP) antigen of the fungus. Importantly, anti-MP antibodies and antibody-secreting B cells were detected in the supernatant and cell cultures, respectively, of vaginal B lymphocytes from infected rats incubated in vitro with vaginal T cells and stimulated with MP. No such specific antibodies were found when using vaginal B cells from uninfected rats. Furthermore, inflammatory and anti-inflammatory cytokines, such as interleukin-2 (IL-2), IL-6 and IL-10, were found in the supernatant of vaginal B cells from infected rats. These data are evidence of a partial anti-Candida protective role of CD3(-) CD5(+) IgM(+) vaginal B lymphocytes in our experimental model. PMID:20402794

Endotracheal tube cuff pressure before, during, and after fixed-wing air medical retrieval.  

PubMed

Abstract Background. Increased endotracheal tube (ETT) cuff pressure is associated with compromised tracheal mucosal perfusion and injuries. No published data are available for Australia on pressures in the fixed-wing air medical retrieval setting. Objective. After introduction of a cuff pressure manometer (Mallinckrodt, Hennef, Germany) at the Royal Flying Doctor Service (RFDS) Base in Dubbo, New South Wales (NSW), Australia, we assessed the prevalence of increased cuff pressures before, during, and after air medical retrieval. Methods. This was a retrospective audit in 35 ventilated patients during fixed-wing retrievals by the RFDS in NSW, Australia. Explicit chart review of ventilated patients was performed for cuff pressures and changes during medical retrievals with pressurized aircrafts. Pearson correlation was calculated to determine the relation of ascent and ETT cuff pressure change from ground to flight level. Results. The mean (± standard deviation) of the first ETT cuff pressure measurement on the ground was 44 ± 20 cmH2O. Prior to retrieval in 11 patients, the ETT cuff pressure was >30 cmH2O and in 11 patients >50 cmH2O. After ascent to cruising altitude, the cuff pressure was >30 cmH2O in 22 patients and >50 cmH2O in eight patients. The cuff pressure was reduced 1) in 72% of cases prior to take off and 2) in 85% of cases during flight, and 3) after landing, the cuff pressure increased in 85% of cases. The correlation between ascent in cabin altitude and ETT cuff pressure was r = 0.3901, p = 0.0205. Conclusions. The high prevalence of excessive cuff pressures during air medical retrieval can be avoided by the use of cuff pressure manometers. Key words: cuff pressure; air medical retrieval; prehospital.

The American Brachytherapy Society Treatment Recommendations for Locally Advanced Carcinoma of the Cervix Part II: High Dose-Rate Brachytherapy  

PubMed Central

Purpose This report presents the 2011 update to the American Brachytherapy Society (ABS) high-dose-rate (HDR) brachytherapy guidelines for locally advanced cervical cancer. Methods Members of the American Brachytherapy Society (ABS) with expertise in cervical cancer brachytherapy formulated updated guidelines for HDR brachytherapy using tandem and ring, ovoids, cylinder or interstitial applicators for locally advanced cervical cancer were revised based on medical evidence in the literature and input of clinical experts in gynecologic brachytherapy. Results The Cervical Cancer Committee for Guideline Development affirms the essential curative role of tandem-based brachytherapy in the management of locally advanced cervical cancer. Proper applicator selection, insertion, and imaging are fundamental aspects of the procedure. Three-dimensional imaging with magnetic resonance or computed tomography or radiographic imaging may be used for treatment planning. Dosimetry must be performed after each insertion prior to treatment delivery. Applicator placement, dose specification and dose fractionation must be documented, quality assurance measures must be performed, and follow-up information must be obtained. A variety of dose/fractionation schedules and methods for integrating brachytherapy with external-beam radiation exist. The recommended tumor dose in 2 Gray (Gy) per fraction radiobiologic equivalence (EQD2) is 80–90 Gy, depending on tumor size at the time of brachytherapy. Dose limits for normal tissues are discussed. Conclusion These guidelines update those of 2000 and provide a comprehensive description of HDR cervical cancer brachytherapy in 2011.

High-Dose Rate Brachytherapy Using Inverse Planning Simulated Annealing for Locoregionally Advanced Cervical Cancer: A Clinical Report With 2-Year Follow-Up  

SciTech Connect

Purpose: We present clinical outcomes of image-guided brachytherapy using inverse planning simulated annealing (IPSA) planned high-dose rate (HDR) brachytherapy boost for locoregionally advanced cervical cancer. Methods and Materials: From February 2004 through December 2006, 51 patients were treated at the University of California, San Francisco with HDR brachytherapy boost as part of definitive radiation for International Federation of Gynecology and Obstetrics Stage IB1 to Stage IVA cervical cancer. Of the patients, 46 received concurrent chemotherapy, 43 with cisplatin alone and 3 with cisplatin/5-fluorouracil. All patients had IPSA-planned HDR brachytherapy boost after whole-pelvis external radiation to a total tumor dose of 85 Gy or greater (for alpha/beta = 10). Toxicities are reported according to National Cancer Institute CTCAE v3.0 (Common Terminology Criteria for Adverse Events version 3.0) guidelines. Results: At a median follow-up of 24.3 months, there were no toxicities of Grade 4 or greater and the frequencies of Grade 3 acute and late toxicities were 4% and 2%, respectively. The proportion of patients having Grade 1 or 2 gastrointestinal and genitourinary acute toxicities was 48% and 52%, respectively. Low-grade late toxicities included Grade 1 or 2 vaginal, gastrointestinal, and hormonal toxicities in 31%, 18%, and 4% of patients, respectively. During the follow-up period, local recurrence developed in 2 patients, regional recurrence developed in 2, and new distant metastases developed in 15. The rates of locoregional control of disease and overall survival at 24 months were 91% and 86%, respectively. Conclusions: Definitive radiation by use of inverse planned HDR brachytherapy boost for locoregionally advanced cervical cancer is well tolerated and achieves excellent local control of disease.

Automated intraoperative calibration for prostate cancer brachytherapy  

SciTech Connect

Purpose: Prostate cancer brachytherapy relies on an accurate spatial registration between the implant needles and the TRUS image, called ''calibration''. The authors propose a new device and a fast, automatic method to calibrate the brachytherapy system in the operating room, with instant error feedback. Methods: A device was CAD-designed and precision-engineered, which mechanically couples a calibration phantom with an exact replica of the standard brachytherapy template. From real-time TRUS images acquired from the calibration device and processed by the calibration system, the coordinate transformation between the brachytherapy template and the TRUS images was computed automatically. The system instantly generated a report of the target reconstruction accuracy based on the current calibration outcome. Results: Four types of validation tests were conducted. First, 50 independent, real-time calibration trials yielded an average of 0.57 {+-} 0.13 mm line reconstruction error (LRE) relative to ground truth. Second, the averaged LRE was 0.37 {+-} 0.25 mm relative to ground truth in tests with six different commercial TRUS scanners operating at similar imaging settings. Furthermore, testing with five different commercial stepper systems yielded an average of 0.29 {+-} 0.16 mm LRE relative to ground truth. Finally, the system achieved an average of 0.56 {+-} 0.27 mm target registration error (TRE) relative to ground truth in needle insertion tests through the template in a water tank. Conclusions: The proposed automatic, intraoperative calibration system for prostate cancer brachytherapy has achieved high accuracy, precision, and robustness.

Nursing considerations in patients with vaginitis.  

PubMed

Vaginitis is defined as an inflammation of the vagina. It can result in symptoms of any or all of the following: discharge, itching and pain, and often irritation or infection of the vulva. There is no specific cause for vaginitis, and many other conditions can cause the symptoms. Vaginitis is a distressing condition that affects many women of reproductive age and beyond, and encompasses candidiasis (also known as thrush), bacterial vaginosis, and trichomoniasis. It can occur in a single episode, or recur throughout a woman's lifetime. Some women will seek medical help, but many more self-treat with over-the-counter medications, suspecting the recurrence of Candida in particular. This article aims to explore the causes, signs and symptoms, and treatments of vaginitis to provide nurses with the necessary background information to feel more confident in dealing with women's health issues.

Vaginal childbirth and pelvic floor disorders.  

PubMed

Childbirth is an important event in a woman's life. Vaginal childbirth is the most common mode of delivery and it has been associated with increased incidence of pelvic floor disorders later in life. In this article, the authors review and summarize current literature associating pelvic floor disorders with vaginal childbirth. Stress urinary incontinence and pelvic organ prolapse are strongly associated with vaginal childbirth and parity. The exact mechanism of injury associating vaginal delivery with pelvic floor disorders is not known, but is likely multifactorial, potentially including mechanical and neurovascular injury to the pelvic floor. Observational studies have identified certain obstetrical exposures as risk factors for pelvic floor disorders. These factors often coexist in clusters; hence, the isolated effect of these variables on the pelvic floor is difficult to study. PMID:23638782

Comparison of prophylactic effects of polyurethane cylindrical or tapered cuff and polyvinyl chloride cuff endotracheal tubes on ventilator-associated pneumonia.  

PubMed

Because microaspiration of contaminated supraglottic secretions past the endotracheal tube cuff is considered to be central in the pathogenesis of pneumonia, improved design of tracheal tubes with new cuff material and shape have reduced the size and number of folds, which together with the addition of suction ports above the cuff to drain pooled subglottic secretions leads to reduced aspiration of oropharyngeal secretions. So we conducted a study to compare the prophylactic effects of polyurethane-cylindrical or tapered cuff and polyvinyl chloride cuff endotracheal tubes (ETT) on ventilator-associated pneumonia. This randomized clinical trial was carried out in a 12 bed surgical intensive care unit. 96 patients expected to require mechanical ventilation more than 96 hours were randomly allocated to one of three following groups: Polyvinyl chloride cuff (PCV) ETT, Polyurethane (PU) cylindrical Sealguard ETT and PU Taperguard ETT. Cuff pressure monitored every three hours 3 days in all patients. Mean cuff pressure didn't have significant difference between three groups during 72 hours. Pneumonia was seen in 11 patients (34%) in group PVC, 8 (25%) in Sealguard and 7 (21%) in Taperguard group. Changes in mean cuff pressure between Sealguard and PVC tubes and also between Taperguard and PVC tubes did not show any significant difference. There was no significant difference in overinflation between three groups. The use of ETT with PU material results in reducing ventilator-associated pneumonia compared to ETT with PVC cuff. In PU tubes Taperguard has less incidence of ventilator-associated pneumonia compared to Sealguard tubes. PMID:23945890

Desflurane analgesia for vaginal delivery.  

PubMed

The use of subanaesthetic concentration of inhalational anaesthetic for vaginal delivery offers many advantages to the mother and newborn. Desflurane, with the characteristics of rapid onset and minimal metabolism, may provide better analgesia and safety for labour pain control. Eighty healthy parturients were randomly assigned to receive either desflurane 1.0-4.5% and oxygen (n = 40) or nitrous oxide 30-60% in oxygen (n = 40). Analgesia was assessed using a score from 0 (no relief) to 4+ (excellent analgesia), amnesia for the delivery, blood loss were recorded. Neonates were evaluated by Apgar scores and neurologic and adaptive capacity scores (NACS). Data were analyzed for statistical significance using Student's t-test or Chi-square when appropriate. Analgesia scores were similar for both groups with more amnesia in desflurane group (23% vs 0% P < 0.05). Blood loss did not differ significantly, 364 ml for the desflurane group and 335 ml for the nitrous oxide group. There were no significant differences for neonatal Apgar score at 1 min or at 5 min or the NACS at 2 hr or 24 hr between the two groups. We conclude that desflurane in subanaesthetic doses is safe and effective inhalation agent for normal delivery but might be associated with amnesia. PMID:7793195

The evolution of brachytherapy treatment planning  

SciTech Connect

Brachytherapy is a mature treatment modality that has benefited from technological advances. Treatment planning has advanced from simple lookup tables to complex, computer-based dose-calculation algorithms. The current approach is based on the AAPM TG-43 formalism with recent advances in acquiring single-source dose distributions. However, this formalism has clinically relevant limitations for calculating patient dose. Dose-calculation algorithms are being developed based on Monte Carlo methods, collapsed cone, and solving the linear Boltzmann transport equation. In addition to improved dose-calculation tools, planning systems and brachytherapy treatment planning will account for material heterogeneities, scatter conditions, radiobiology, and image guidance. The AAPM, ESTRO, and other professional societies are working to coordinate clinical integration of these advancements. This Vision 20/20 article provides insight into these endeavors.

Latissimus dorsi transfer for treatment of irreparable rotator cuff tears.  

PubMed

Massive rotator cuff tendon ruptures are not uncommon in older patients. We propose the transfer of the latissimus dorsi muscle for treatment of irreparable ruptures associated with functional impairment and chronic pain. Five women and 11 men were so treated and reviewed with an average follow-up of 26 months. The mean age was 60 years. Four patients also had subscapularis deficiency. Results were assessed with the Constant score and the Oxford shoulder score. Humeral head position was analysed. Statistical analysis was performed by the Wilcoxon non-parametrical test. The Constant score increased by 24.2% (p?=?0.001) with all parameters showing improvement. Nine patients showed improved humeral head positioning in internal rotation. Three of four patients with a deficient subscapularis had unfavourable results. Latissimus dorsi transfer for the treatment of irreparable massive rotator cuff tears leads to a substantial clinical improvement. An intact subscapularis tendon is mandatory. PMID:20155494

Anterior superior instability with rotator cuff tearing: SLAC lesion.  

PubMed

Anterosuperior instability of the shoulder may occur from a variety of pathologic lesions. We describe a specific entity, the SLAC (superior labrum, anterior cuff) lesion that involves an association of anterior-superior labral tear with a partial supraspinatus tear. We retrospectively isolated a group of 40 patients with this lesion. The presenting complaints, physical examination findings, surgical findings, and results were isolated. Overhead activities were the most common etiology; load and shift instability testing and whipple rotator cuff testing were the most common physical examination findings. Surgical repair was successful in 37 of the 40 patients. The SLAC lesion is a definable clinical entity with predictable history, examination, surgical pathology, and satisfactory results from surgery. PMID:11888140

Biologically based strategies to augment rotator cuff tears  

PubMed Central

Lesions of the rotator cuff (RC) are among the most frequent tendon injuries. In spite of the developments in both open and arthroscopic surgery, RC repair still very often fails. In order to reduce the failure rate after surgery, several experimental in vitro and in vivo therapy methods have been developed for biological improvement of the reinsertion. This article provides an overview of the current evidence for augmentation of RC reconstruction with growth factors. Furthermore, potential future therapeutic approaches are discussed. We performed a comprehensive search of the PubMed database using various combinations of the keywords “tendon,” “rotator cuff,” “augmentation,” “growth factor,” “platelet-rich fibrin,” and “platelet-rich plasma” for publications up to 2011. Given the linguistic capabilities of the research team, we considered publications in English, German, French, and Spanish. We excluded literature reviews, case reports, and letters to the editor.

Wearable PWV technologies to measure Blood Pressure: eliminating brachial cuffs.  

PubMed

The clinical demand for technologies to monitor Blood Pressure (BP) in ambulatory scenarios with minimal use of inflation cuffs is strong: new generation of BP monitors are expected to be not only accurate, but also non-occlusive. In this paper we review recent advances on the use of the so-called Pulse Wave Velocity (PWV) technologies to estimate BP in a beat-by-beat basis. After introducing the working principle and underlying methodological limitations, two implementation examples are provided. Pilot studies have demonstrated that novel PWV-based BP monitors depict accuracy scores falling within the limits of the British Hypertensive Society (BHS) Grade A standard. The reported techniques pave the way towards ambulatory-compliant, continuous and non-occlusive BP monitoring devices, where the use of inflation cuffs is drastically reduced. PMID:24110633

Nonarthroplasty options for the management of massive and irreparable rotator cuff tears.  

PubMed

Massive, irreparable rotator cuff tears remain a clinical challenge. In low-demand patients, debridement of the tear may relieve pain. Partial repair using the technique of margin convergence decreases the size of the tear gap and reduces strain. Biceps tenotomy or tenodesis has a role in providing pain relief in massive rotator cuff tears. Tendon transfers offer good results in patients with massive, irreparable rotator cuff tears. The treatment modality specifically chosen for the massive, irreparable rotator cuff tear must be tailored to the individual patient, their needs and expectations, and their ability to comply with intensive rehabilitation.

Erectile Function Durability Following Permanent Prostate Brachytherapy  

SciTech Connect

Purpose: To evaluate long-term changes in erectile function following prostate brachytherapy. Methods and Materials: This study included 226 patients with prostate cancer and preimplant erectile function assessed by the International Index of Erectile Function-6 (IIEF-6) who underwent brachytherapy in two prospective randomized trials between February 2001 and January 2003. Median follow-up was 6.4 years. Pre- and postbrachytherapy potency was defined as IIEF-6 >= 13 without pharmacologic or mechanical support. The relationship among clinical, treatment, and dosimetric parameters and erectile function was examined. Results: The 7-year actuarial rate of potency preservation was 55.6% with median postimplant IIEF of 22 in potent patients. Potent patients were statistically younger (p = 0.014), had a higher preimplant IIEF (p < 0.001), were less likely to be diabetic (p = 0.002), and were more likely to report nocturnal erections (p = 0.008). Potency preservation in men with baseline IIEF scores of 29-30, 24-28, 18-23, and 13-17 were 75.5% vs. 73.6%, 51.7% vs. 44.8%, 48.0% vs. 40.0%, and 23.5% vs. 23.5% in 2004 vs. 2008. In multivariate Cox regression analysis, preimplant IIEF, hypertension, diabetes, prostate size, and brachytherapy dose to proximal penis strongly predicted for potency preservation. Impact of proximal penile dose was most pronounced for men with IIEF of 18-23 and aged 60-69. A significant minority of men who developed postimplant impotence ultimately regained erectile function. Conclusion: Potency preservation and median IIEF scores following brachytherapy are durable. Thoughtful dose sparing of proximal penile structures and early penile rehabilitation may further improve these results.

Design and optimization of a brachytherapy robot  

NASA Astrophysics Data System (ADS)

Trans-rectal ultrasound guided (TRUS) low dose rate (LDR) interstitial brachytherapy has become a popular procedure for the treatment of prostate cancer, the most common type of non-skin cancer among men. The current TRUS technique of LDR implantation may result in less than ideal coverage of the tumor with increased risk of negative response such as rectal toxicity and urinary retention. This technique is limited by the skill of the physician performing the implant, the accuracy of needle localization, and the inherent weaknesses of the procedure itself. The treatment may require 100 or more sources and 25 needles, compounding the inaccuracy of the needle localization procedure. A robot designed for prostate brachytherapy may increase the accuracy of needle placement while minimizing the effect of physician technique in the TRUS procedure. Furthermore, a robot may improve associated toxicities by utilizing angled insertions and freeing implantations from constraints applied by the 0.5 cm-spaced template used in the TRUS method. Within our group, Lin et al. have designed a new type of LDR source. The "directional" source is a seed designed to be partially shielded. Thus, a directional, or anisotropic, source does not emit radiation in all directions. The source can be oriented to irradiate cancerous tissues while sparing normal ones. This type of source necessitates a new, highly accurate method for localization in 6 degrees of freedom. A robot is the best way to accomplish this task accurately. The following presentation of work describes the invention and optimization of a new prostate brachytherapy robot that fulfills these goals. Furthermore, some research has been dedicated to the use of the robot to perform needle insertion tasks (brachytherapy, biopsy, RF ablation, etc.) in nearly any other soft tissue in the body. This can be accomplished with the robot combined with automatic, magnetic tracking.

Brachytherapy needle deflection evaluation and correction  

SciTech Connect

In prostate brachytherapy, an 18-gauge needle is used to implant radioactive seeds. This thin needle can be deflected from the preplanned trajectory in the prostate, potentially resulting in a suboptimum dose pattern and at times requiring repeated needle insertion to achieve optimal dosimetry. In this paper, we report on the evaluation of brachytherapy needle deflection and bending in test phantoms and two approaches to overcome the problem. First we tested the relationship between needle deflection and insertion depth as well as whether needle bending occurred. Targeting accuracy was tested by inserting a brachytherapy needle to target 16 points in chicken tissue phantoms. By implanting dummy seeds into chicken tissue phantoms under 3D ultrasound guidance, the overall accuracy of seed implantation was determined. We evaluated methods to overcome brachytherapy needle deflection with three different insertion methods: constant orientation, constant rotation, and orientation reversal at half of the insertion depth. Our results showed that needle deflection is linear with needle insertion depth, and that no noticeable bending occurs with needle insertion into the tissue and agar phantoms. A 3D principal component analysis was performed to obtain the population distribution of needle tip and seed position relative to the target positions. Our results showed that with the constant orientation insertion method, the mean needle targeting error was 2.8 mm and the mean seed implantation error was 2.9 mm. Using the constant rotation and orientation reversal at half insertion depth methods, the deflection error was reduced. The mean needle targeting errors were 0.8 and 1.2 mm for the constant rotation and orientation reversal methods, respectively, and the seed implantation errors were 0.9 and 1.5 mm for constant rotation insertion and orientation reversal methods, respectively.

Repetitive throwing or other overhead activity places great stress on the shoulder. As a result, the shoulder is a common site of injury in athletes. Addressing throwing-related injuries requires an understanding of throwing biomechanics and pathology. Nonoperative treatment is directed at restoring strength, flexibility, and neuromuscular control to the entire kinetic chain. Surgery is indicated when nonoperative treatment fails, and is directed at correcting labral, capsular, and rotator cuff pathology. PMID:20497808

Paraspinal tumors: Techniques and results of brachytherapy  

SciTech Connect

Because of their proximity to nerve roots and the spinal cord, it is frequently difficult to achieve complete resection of paraspinal tumors. We have used brachytherapy in an attempt to prevent local recurrence and its associated neurological sequelae. This report analyzes our experience with 35 patients to determine the feasibility, optimal techniques, and efficacy of this approach. The tumor types were non small-cell lung cancer (18), sarcomas (9), and other tumor types (8). Temporary, single plane implants using Ir-192 (median minimum peripheral dose 3000 cGy) were used in 21 patients, and permanent I-125 implants were used in 14 cases (median matched peripheral dose 12,500 cGy). Local control was achieved in 51% (18/35). However, local control was poor when lung cancers were implanted and in cases where the dura was exposed. Radiation myelitis did not occur despite the combined effects of previous external beam radiotherapy (N = 21) and brachytherapy. Our experience demonstrates that combined surgery and paraspinal brachytherapy can be performed with acceptable toxicity and is reasonably effective in preventing local relapse and its neurologic sequelae, particularly for tumors other than lung cancers.

Postanesthesia patients with large upper arm circumference: is use of an "extra-long" adult cuff or forearm cuff placement accurate?  

PubMed

The purpose of this study was to determine if blood pressure (BP) measured in the forearm or with an extra-long BP cuff in the upper arm accurately reflects BP measured in the upper arm with an appropriately sized BP cuff in patients with large upper arm circumference. A method-comparison design was used with a convenience sample of 49 PACU patients. Noninvasive blood pressures were obtained in two different locations (forearm; upper arm) and in the upper arm with an extra-long adult and recommended large adult cuff sizes. Data were analyzed by calculating bias and precision for the BP cuff size and location and Student's t-tests, with P < .0125 considered significant. Significantly higher forearm systolic (P < .0001) and diastolic (P < .0002) BP measurements were found compared to BP obtained in the upper arm with the reference standard BP cuff. Significantly higher systolic (t(48df) = 5.38, P < .0001), but not diastolic (t(48df) = 4.11, P < .019), BP differences were found for BP measured with the extra-long cuff at the upper arm site compared to the upper arm, reference standard BP. Findings suggest that the clinical practice of using the forearm or an extra-long cuff in the upper arm for BP measurement in post anesthesia patients with large upper arm circumferences may result in inaccurate BP values.

[How to prepare the brachytherapy of the future].  

PubMed

For more than a century, brachytherapy has been a treatment of choice for delivering a high dose in a small volume. However, over the past 15 years, this irradiation technique has stalled. Even so, brachytherapy allows the delivery of the right dose at the right place by dispensing with target volume motion and repositioning. The evolution of brachytherapy can be based on a road-map including at least the following three points: the acquisition of clinical evidence, teaching and valuation of the procedures. The evolution of brachytherapy will be also impacted by technological considerations (end of the production of low dose rate 192 iridium wires). Regarding the evolution toward a personalized treatment, brachytherapy of the future should take its place as a partner of other modern external beam radiation techniques, be performed by experimented actors (physicians, physicists, technicians, etc.) who received adequate training, and be valued in proportion to the delivered medical service.

In pediatric gynecology, inflammatory vulvo-vaginitis are very common. Their diagnosis cannot be based either on the symptoms (itching or pain) or on the signs (leucoxanthorrhea) for these classifications are "non-specific". At the Consulting Room of pediatric gynecology of the Vittore Buzzi Hospital, 215 "non-specific" vulvo-vaginitis cases have been analyzed through bacteriological and microscopical examinations of vaginal secretions. The vaginal tampon resulted negative in 53% of the cases and positive in the remaining 47%. Comparing these results with microscopical examinations we obtain: 81.8% of sensibility, 77.4% of specificity, 87.8% of negative predictive value and 62.2% of positive predictive value. In particular, this last figure is influenced by the high number of false positives of the vaginal tampons, due to the growth "in vitro" of opportunist germs momentarily quiescent "in vivo". Thus it is useful to associated the microscopical examination (that will indicate all the cases in need of treatment) and the bacteriological examination (that will indicate the right cure).

Breech vaginal delivery at or near term.  

PubMed

Three percent to 4% of term fetuses will be breech at delivery. Evidence from randomized controlled trials has found a policy of planned cesarean section to be significantly better for the singleton fetus in breech presentation at term compared to a policy of planned vaginal birth. However, some women may wish to avoid cesarean section and for others, cesarean section may not be possible. We undertook this review to identify factors associated with higher and lower risk of adverse fetal or neonatal outcome at term during vaginal breech delivery. We searched MEDLINE from 1966 to 2002 using the search terms vaginal breech delivery and breech presentation and retrieved all relevant articles. We also reviewed personal references and reference lists of articles retrieved. Women who are older or who have a fetus that is either in footling presentation, has a hyperextended head or is estimated to weigh <2500 g or >4000 g may be at higher risk of adverse fetal outcome. Prolonged labor or not having an experienced clinician at vaginal breech birth may also increase the risk. Women with a fetus in breech presentation at term should be offered the option of delivery by planned cesarean section and should be informed that this will reduce their risk of adverse fetal or neonatal outcome. Practitioners should develop and maintain skills at vaginal breech delivery for those women not wishing or not able to be delivered by cesarean section. PMID:12641301

Effect of Vaginal Lubricants on Natural Fertility  

PubMed Central

Objective Over-the-counter vaginal lubricants have been shown to negatively affect in vitro sperm motility. The objective of this study was to estimate the effect of vaginal lubricant use during procreative intercourse on natural fertility. Methods Women aged 30–44 years with no history of infertility who had been trying to conceive for less than 3 months completed a baseline questionnaire on vaginal lubricant use. Subsequently, women kept a diary to record menstrual bleeding, intercourse, and vaginal lubricant use and conducted standardized pregnancy testing for up to 6 months. Diary data were used to determine the fertile window and delineate lubricant use during the fertile window. A proportional hazards model was used to estimate fecundability ratios with any lubricant use in the fertile window considered as a time-varying exposure. Results Of the 296 participants, 75 (25%) stated in their baseline questionnaire that they use vaginal lubricants while attempting to conceive. Based on daily diary data, 57% of women never used a lubricant, 29% occasionally used a lubricant, and 14% used a lubricant frequently. Women who used lubricants during the fertile window had similar fecundability to those women who did not use lubricants (fecundability ratio 1.05, 95% CI: 0.59, 1.85) after adjusting for age, partner race, and intercourse frequency in the fertile window. Conclusion Lubricants are commonly used by couples during procreative intercourse. Lubricant use during procreative intercourse does not appear to reduce the probability of conceiving.

AV, bacterial vaginosis (BV), vulvovaginal candidiasis (VVC), trichomonal vaginitis (TV), and cytolytic vaginosis (CV) were diagnosed based on symptoms, sign and vaginal discharge examination. RESULTS: Among 516 cases, AV cases were found in 14.7% (76/516), and AV was common vaginal infection. AV mixed infections was diagnosed in 58% (44/76), including mixed with BV (45%, 20/44), mixed with VVC (30%, 13/44), and mixed with TV (25%, 11/44). Those common symptom of AV were yellow vaginal discharge (63%, 20/32), more vaginal discharge (44%, 14/32). Vaginal pH value was usually more than 4.5 (84%, 27/32). Vaginal cleanliness mainly was grade III - IV (88%, 28/32). Six cases with enterococcus faecium and 4 cases with streptococci were frequently isolated. The symptom and sign of mixed AV infection was atypical. CONCLUSIONS: Aerobic vaginitis is a common lower vaginal infection and easily mixed with other pathogens, especially with BV, VVC or TV. When patients were diagnosed with AV or other vaginal infection, it should be mentioned whether those patients have mixed vaginal infection or AV. PMID:21211421

Penile brachytherapy: Results for 49 patients  

SciTech Connect

Purpose: To report results for 49 men with squamous cell carcinoma (SCC) of the penis treated with primary penile interstitial brachytherapy at one of two institutions: the Ottawa Regional Cancer Center, Ottawa, and the Princess Margaret Hospital, Toronto, Ontario, Canada. Methods and Materials: From September 1989 to September 2003, 49 men (mean age, 58 years; range, 22-93 years) had brachytherapy for penile SCC. Fifty-one percent of tumors were T1, 33% T2, and 8% T3; 4% were in situ and 4% Tx. Grade was well differentiated in 31%, moderate in 45%, and poor in 2%; grade was unspecified for 20%. One tumor was verrucous. All tumors in Toronto had pulsed dose rate (PDR) brachytherapy (n = 23), whereas those in Ottawa had either Iridium wire (n 22) or seeds (n = 4). Four patients had a single plane implant with a plastic tube technique, and all others had a volume implant with predrilled acrylic templates and two or three parallel planes of needles (median, six needles). Mean needle spacing was 13.5 mm (range, 10-18 mm), mean dose rate was 65 cGy/h (range, 33-160 cGy/h), and mean duration was 98.8 h (range, 36-188 h). Dose rates for PDR brachytherapy were 50-61.2 cGy/h, with no correction in total dose, which was 60 Gy in all cases. Results: Median follow-up was 33.4 months (range, 4-140 months). At 5 years, actuarial overall survival was 78.3% and cause-specific survival 90.0%. Four men died of penile cancer, and 6 died of other causes with no evidence of recurrence. The cumulative incidence rate for never having experienced any type of failure at 5 years was 64.4% and for local failure was 85.3%. All 5 patients with local failure were successfully salvaged by surgery; 2 other men required penectomy for necrosis. The soft tissue necrosis rate was 16% and the urethral stenosis rate 12%. Of 8 men with regional failure, 5 were salvaged by lymph node dissection with or without external radiation. All 4 men with distant failure died of disease. Of 49 men, 42 had an intact and tumor-free penis at last follow-up or death. The actuarial penile preservation rate at 5 years was 86.5%. Conclusions: Brachytherapy is an effective treatment for T1, T2, and selected T3 SCC of the penis. Close follow-up is mandatory because local failures and many regional failures can be salvaged by surgery.

Vaginal T lymphocyte population kinetics during experimental vaginal candidosis: evidence for a possible role of CD8+ T cells in protection against vaginal candidosis  

PubMed Central

Vaginal candidosis represents a significant health problem to women of childbearing age worldwide. It has been postulated that localized T cells play a role in protection against vaginal candidosis. In an attempt to evaluate the role of vaginal T cells in protection against vaginal candidosis, T cell population kinetics was evaluated using an oestrogen-dependent vaginal candidosis murine model. Vaginal T lymphocytes were isolated at different time points post C. albicans inoculation, viable cells were enumerated, phenotypically analysed for the expression of CD3, CD4 and CD8 T cell markers and absolute numbers of T cell subsets were calculated. Oestrogen-induced persistence of vaginal candidosis resulted in a significant increase in the total number of vaginal lymphocytes within 24–48 h post infection; increased vaginal lymphocyte numbers persisted throughout the infection period. The number of CD3+ T cells dramatically increased following C. albicans administration and was maintained at high levels throughout the infection period. The majority of CD3+ T cells were of the CD8+ type; however, considerable numbers of both CD4+ T cells and CD4+CD8+ T cells were also observed throughout the infection period. The considerable and persistent increase in vaginal T cell numbers in general and that of CD8+ T cells in particular are evidence of the possible role played by localized T cells in protection against vaginal candidosis.

SU-GG-T-49: Real Time Dose Verification for Novel Shielded Balloon Brachytherapy  

SciTech Connect

Purpose: The validation of a novel approach for reducing skindoses to an acceptable level during Accelerated Partial Breast Irradiation (APBI) when the balloon-to-skin distance is inadequate (less than 7 mm) is reported. The study uses a real time dose verification method for a metallic shielded balloon applicator using scintillation fiber technology. Method and Materials: Partial shielding of the radiationdose to the skin using iron or other ferrous powder could enable the extension of APBI to some patients. With small external and pre-determined magnetic fields (Brachytherapy treatments with relatively weak magnetic fields. Additional measurements provided negligible corrections (< few %) on the saline water density from the suspended ironpowder.Conclusion: This project opens the possibility to increasing the survival expectancy and minimizing negative side effects during brachytherapy treatments, as well as improving cosmetic outcome for all APBI patients. The proposed method may also be used in other procedures for brain, heart, rectal, or vaginal cancers.

A Novel Technique for Anterior Vaginal Wall Prolapse Repair: Anterior Vaginal Wall Darn  

PubMed Central

Aim. The aim of this study is to introduce a new technique, anterior vaginal wall darn (AVWD), which has not been used before to repair the anterior vaginal wall prolapse, a common problem among women. Materials and Methods. Forty-five women suffering from anterior vaginal wall prolapse were operated on with a new technique. The anterior vaginal wall was detached by sharp and blunt dissection via an incision beginning from the 1?cm proximal aspect of the external meatus extending to the vaginal apex, and the space between the tissues that attach the lateral walls of the vagina to the arcus tendineus fascia pelvis (ATFP) was then darned. Preoperation and early postoperation evaluations of the patients were conducted and summarized. Results. Data were collected six months after operation. Cough stress test (CST), Pelvic Organ Prolapse Quantification (POP-Q) evaluation, Incontinence Impact Questionnaire (IIQ-7), and Urogenital Distress Inventory (UDI-6) scores indicated recovery. According to the early postoperation results, all patients were satisfied with the operation. No vaginal mucosal erosion or any other complications were detected. Conclusion. In this initial series, our short-term results suggested that patients with grade II-III anterior vaginal wall prolapsus might be treated successfully with the AVWD method.

Vaginal delivery through annular placenta -- case report.  

PubMed

Annular placenta is an extremely rare morphological type of human placenta. It is commonly related to placental vessel abnormalities frequently causing antenatal and postnatal hemorrhage and operative delivery. Gravida 4 para 1 had an uneventful course of pregnancy and normal vaginal delivery followed by moderate postpartum hemorrhage. Hemorrhage was found to be local in origin but the placenta was annular in shape and the newborn was delivered through one of the openings. Annular placenta was not recognized before delivery. Its implantation site was in the lower uterine segment but high enough to allow the passage of the fetus through its annular defect and vaginal birth. To our knowledge, this is a first report of annular placenta ending in normal vaginal delivery. PMID:23630149

Operative vaginal delivery: current trends in obstetrics.  

PubMed

After centuries of use in obstetrics, have forceps and vacuum deliveries become a dying art? Contemporary trends in operative vaginal delivery show increasing numbers of vacuum deliveries and decreasing numbers of forceps deliveries worldwide. Primary drivers of such trends include concerns over neonatal and maternal safety as well as fewer clinicians skilled in forcep use. Current literature reports a comparable efficacy rate for the two instruments, as well as a decrease in maternal morbidity compared with cesarean section. It has also been suggested that the neonatal morbidity once associated with operative vaginal delivery may actually be a function of an abnormal labor process itself, rather than a consequence of an operative vaginal intervention. Both the American College and the Royal College of Obstetricians and Gynecologists continue to support the use of both vacuum and forceps and strongly encourage residency programs to incorporate the teaching of these skills into their curricula.

Efficacy and Tolerability of Fitostimoline (Vaginal Cream, Ovules, and Vaginal Washing) and of Benzydamine Hydrochloride (Tantum Rosa Vaginal Cream and Vaginal Washing) in the Topical Treatment of Symptoms of Bacterial Vaginosis  

PubMed Central

Two hundred and 91 patients showing signs and symptoms of bacterial vaginosis (BV) were randomized to receive topical treatment with Fitostimoline (vaginal cream and vaginal ovules + vaginal washing) or benzydamine hydrochloride (vaginal cream + vaginal washing) for 7 days. Signs (leucorrhoea, erythema, oedema, and erosion) and symptoms (burning, pain, itching, vaginal dryness, dyspareunia, and dysuria) (scored 0–3) were evaluated at baseline and at the end of treatment; the total symptoms score (TSS) was also calculated. In 125 patients, a bacterial vaginosis was confirmed by vaginal swab test. The primary efficacy variable analysis, that is, the percentage of patients with therapeutic success (almost complete disappearance of signs and symptoms), demonstrated that Fitostimoline ovules and vaginal cream were therapeutically equivalent and that pooled Fitostimoline treatment was not inferior to benzydamine hydrochloride. All the treatments were well tolerated, with only minor local adverse events infrequently reported. The results of this study confirmed that gynaecological Fitostimoline is a safe and effective topical treatment for BV.

The role of the biceps tendon in massive rotator cuff tears.  

PubMed

Tendinopathy of the long head of the biceps (LHB) tendon commonly occurs in patients with rotator cuff tears, and the inflammation of one head tends to lead to inflammation of the other. Many theories have been proposed regarding the function of the LHB tendon; however, its exact purpose is poorly understood. It has been described as an important stabilizer of the glenohumeral joint, a depressor of the humeral head, and as a vestigial structure. The LHB tendon can be a significant source of pain in patients with rotator cuff tears. The appropriate treatment depends on the patient's age, comorbidities, activity level, extent of disability, the presence of rotator cuff arthropathy, and the quality of the rotator cuff tissue. Conservative treatment is usually attempted first, with modalities such as nonsteroidal anti-inflammatory drugs, corticosteroid injections, physical therapy, and activity modification. If symptoms persist, biceps tenotomy or tenodesis may be combined with rotator cuff repair, depending on the quality of the rotator cuff tissue, the severity of rotator cuff arthropathy, and the willingness of the patient to comply with postoperative immobilization and rehabilitation. Even when rotator cuff repair is not possible, isolated tenotomy or tenodesis of the LHB tendon can provide substantial pain relief. PMID:22301226

Indications for Surgery in Clinical Outcome Studies of Rotator Cuff Repair  

PubMed Central

Full-thickness tears of the rotator cuff are common, but there is no clear consensus regarding indications for rotator cuff surgery. Because some patients with full-thickness rotator cuff tears who are asymptomatic or symptomatic can be successfully treated nonoperatively, clinical outcome studies of rotator cuff repair should describe the subjects in detail to allow appropriate interpretation of the results. However, we hypothesized the indications for surgery are poorly described in outcome studies of rotator cuff surgery. We undertook a detailed literature review over 11 years of six major orthopaedic journals to assess whether the indications for surgery were described adequately in studies of rotator cuff repair. Eighty-six papers fit the criteria for the study and were reviewed. Limitations of activities of daily living (31%), failure of nonoperative treatment (52%), duration of nonoperative treatment (26%), and history of nocturnal pain (16%) were reported in a minority of papers overall. The patients’ characteristics and indications for surgery were not described in a majority of clinical outcome studies of rotator cuff repair. It is important for these factors to be considered and reported because, without this information, the reasons for and results of rotator cuff repair are difficult to interpret. Level of Evidence: Level III, prognostic study. See the Guidelines for Authors for a complete description of levels of evidence.

The current state of intraoperative interstitial brachytherapy in lung cancer.  

PubMed

Low dose-rate intraoperative brachytherapy allows for a more precise tumor localization of the delivered radiation and its easier adaptation to the tumor shape than it is possible with external radiation. As a result a higher dose is usually delivered to the tumor volume and the damage to the normal lung is less. In an attempt to determine the value of lung brachytherapy we provide in this article a complete review of the evolution of brachytherapy in lung cancer at Memorial Sloan-Kettering Cancer Center, an experience which exceeds 1,000 patients. The use of encapsulated sources of I-125, greatly reduced radiation outside the treatment volume and simplified medical and nursing staff radiation protection. Lung brachytherapy in combination with surgery and postoperative external radiation, improved local tumor control in advanced tumors (from 63% to 76%) with no increase in late pulmonary morbidity, but only a modest survival advantage. The results of brachytherapy in patients with early lung cancer who had limited pulmonary reserve, suggest that intraoperative brachytherapy is an effective alternative treatment option. The limited experience with interstitial brachytherapy under fluoroscopic and CT guidance is encouraging, but needs more investigation. PMID:2848787

The shoulder is a common source of disability resulting from traumatic and degenerate tears of the rotator cuff, subacromial impingement, and osteoarthritis. Nonoperative management has focused on treatment of the predisposing factors, the use of analgesics and anti-inflammatory medication usually in association with local anesthetic and steroid injections. Surgical intervention allows debridement of the degenerate cuff and partial thickness cuff tears, subacromial bursitis, impinging bone spurs and osteophytes together with rotator cuff repairs. Repairs of degenerate and torn tissue are often prone to failure due to many intrinsic and extrinsic factors. It is assumed that some biological therapies might improve clinical, mechanical, and histologic outcomes. Injections of platelet-rich plasma (PRP) have led to reduced pain and improved recovery in other degenerate pathologies areas together with the restoration of function. This study reviews the current literature on PRP and in particular discusses its relevance in the treatment of rotator cuff tears. PMID:21822108

[Contribution of MRI to the preoperative evaluation of rotator cuff tears].  

PubMed

The authors report a series of 38 patients who had been examined by MRI and then operated for a rotator cuff syndrome. The correlation between the description of the cuff lesions after MRI and the surgical observations were excellent for 37 patients. In one case MRI showed a false image of tear of the supra spinatus m. on its anterior edge. This was due to a bad knowledge of the anatomy of the muscle and tendon and to a poor orientation of the frontal cut plane. This study was completed with MRI and anatomic study of 12 non embalmed cadaveric shoulders. The results showed that MRI was very sensitive (0.93) and specific (0.94) for the diagnosis of rotator cuff tears. MRI allowed also to show partial tears of the tendons of the rotator cuff. The authors propose a MRI classification of cuff lesions which permits to establish a good surgical planning. PMID:1812516

A Novel MRI Marker for Prostate Brachytherapy  

SciTech Connect

Purpose: Magnetic resonance imaging (MRI) is the optimal imaging modality for the prostate and surrounding critical organ structures. However, on MRI, the titanium radioactive seeds used for brachytherapy appear as black holes (negative contrast) and cannot be accurately localized. We sought to develop an encapsulated contrast agent marker (ECAM) with high-signal intensity on MRI to permit accurate localization of radioactive seeds with MRI during and after prostate brachytherapy. Methods and Materials: We investigated several agents with paramagnetic and superparamagnetic properties. The agents were injected into titanium, acrylic, and glass seeds, which were linked together in various combinations and imaged with MRI. The agent with the greatest T1-weighted signal was tested further in a canine prostate and agarose phantom. Studies were performed on a 1.5-T clinical MRI scanner. Results: The cobalt-chloride complex contrast (C4) agent with stoichiometry (CoCl{sub 2}){sub 0.8}(C{sub 2}H{sub 5}NO{sub 2}){sub 0.2} had the greatest T1-weighted signal (positive contrast) with a relaxivity ratio >1 (r{sub 2}/r{sub 1} = 1.21 {+-} 0.29). Acrylic-titanium and glass-titanium seed strands were clearly visualized with the encapsulated contrast agent marker. Conclusion: We have developed a novel ECAM that permits positive identification of the radioactive seeds used for prostate brachytherapy on MRI. Preclinical in vitro phantom studies and in vivo canine studies are needed to further optimize MRI sequencing techniques to facilitate MRI-based dosimetry.

Neovascularization Prevalence in the Supraspinatus of Patients With Rotator Cuff Tendinopathy.  

PubMed

OBJECTIVE:: A high prevalence of neovascularity in lower extremity tendinopathies has been reported. Neovascularity in those with rotator cuff tendinopathy exclusively has not been examined. The objective was to determine the prevalence of neovascularization in patients with rotator cuff tendinopathy compared with asymptomatic controls. DESIGN:: Single-blind cross-sectional study. SETTING:: Research laboratory. PARTICIPANTS:: Participants (n = 40; age = 44.9 years, 23-62 years; 20 females) with rotator cuff tendinopathy (n = 20) but without full-thickness rotator cuff tears, and asymptomatic controls that were age, gender, and hand dominance matched (n = 20) to the patients. INTERVENTIONS:: The participants laying in supine had their shoulder positioned in internal rotation and extension. Ultrasound images were collected of the supraspinatus tendon and subacromial bursae in the transverse and longitudinal planes using a linear transducer in color Doppler mode. MAIN OUTCOME MEASURES:: Images were assessed for neovascularization by 2 trained raters who were blinded to group (rotator cuff tendinopathy or asymptomatic group). RESULTS:: No statistically significant difference in neovascularization was identified between participants with and without rotator cuff tendinopathy (? = 0.13, df = 1, P = 0.72). Neovascularization was identified in 6 of 20 patients with rotator cuff tendinopathy (30%) and 5 of 20 asymptomatic control participants (25%). CONCLUSIONS:: The authors found no differences in neovascularization rate in patients with rotator cuff tendinopathy (30%) and asymptomatic controls (25%). The study indicates that neovascularization is not related to presence of symptomatic tendinopathy in those with rotator cuff tendinopathy. Neovascularization may not be a relevant sonographic finding to aid the clinical assessment of those with rotator cuff tendinopathy. PMID:23732364

Interstitial brachytherapy using virtual planning and Doppler transrectal ultrasonography guidance for internal iliac lymph node metastasis.  

PubMed

To expand the indications for high-dose-rate interstitial brachytherapy (HDR-ISBT) for deep-seated pelvic tumors, we investigated the usefulness of Doppler transrectal ultrasonography (TRUS) guidance and virtual planning. The patient was a 36-year-old female. She had right internal iliac lymph node oligometastasis of vaginal cancer 12 months after radical radiotherapy. The tumor could not be found by gray-scale TRUS and physical examination. Virtual planning was performed using computed tomography with template and vaginal cylinder insertion. We uploaded the images to our treatment planning software and reconstructed the contours of the clinical target volume (CTV) and right internal iliac vessel. Virtual needle applicators were plotted using the template holes for virtual planning. At the time of implantation, Doppler TRUS was used to prevent vessel injury by needle applicators. Applicators were implanted in accordance with virtual planning and Doppler TRUS could detect the right iliac vessel. The percentage of CTV covered by the prescribed dose was 99.8%. The minimum dose received by the maximally irradiated 0.1-cc volume for the right internal iliac vessel was 95% prescribed dose. Complete response was achieved, however, radiological findings showed marginal recurrence at 15 months after HDR-ISBT. Post-radiation neuropathy occurred as a late complication four months after treatment; however, the pain was well controlled by medication. We consider that virtual planning and Doppler TRUS are effective methods in cases where it is difficult to detect the tumor by physical examination and gray-scale TRUS, thereby expanding the indications for ISBT.

Protocols for vaginal inoculation and sample collection in the experimental mouse model of Candida vaginitis.  

PubMed

Vulvovaginal candidiasis (VVC), caused by Candida species, is a fungal infection of the lower female genital tract that affects approximately 75% of otherwise healthy women during their reproductive years. Predisposing factors include antibiotic usage, uncontrolled diabetes and disturbance in reproductive hormone levels due to pregnancy, oral contraceptives or hormone replacement therapies. Recurrent VVC (RVVC), defined as three or more episodes per year, affects a separate 5 to 8% of women with no predisposing factors. An experimental mouse model of VVC has been established and used to study the pathogenesis and mucosal host response to Candida. This model has also been employed to test potential antifungal therapies in vivo. The model requires that the animals be maintained in a state of pseudoestrus for optimal Candida colonization/infection. Under such conditions, inoculated animals will have detectable vaginal fungal burden for weeks to months. Past studies show an extremely high parallel between the animal model and human infection relative to immunological and physiological properties. Differences, however, include a lack of Candida as normal vaginal flora and a neutral vaginal pH in the mice. Here, we demonstrate a series of key methods in the mouse vaginitis model that include vaginal inoculation, rapid collection of vaginal specimens, assessment of vaginal fungal burden, and tissue preparations for cellular extraction/isolation. This is followed by representative results for constituents of vaginal lavage fluid, fungal burden, and draining lymph node leukocyte yields. With the use of anesthetics, lavage samples can be collected at multiple time points on the same mice for longitudinal evaluation of infection/colonization. Furthermore, this model requires no immunosuppressive agents to initiate infection, allowing immunological studies under defined host conditions. Finally, the model and each technique introduced here could potentially give rise to use of the methodologies to examine other infectious diseases of the lower female genital tract (bacterial, parasitic, viral) and respective local or systemic host defenses.

Liposomal gels for vaginal drug delivery.  

PubMed

The aim of our study was to develop a liposomal drug carrier system, able to provide sustained and controlled release of appropriate drug for local vaginal therapy. To optimise the preparation of liposomes with regards to size and entrapment efficiency, liposomes containing calcein were prepared by five different methods. Two optimal liposomal preparations (proliposomes and polyol dilution liposomes) were tested for their in vitro stability in media that simulate human vaginal conditions (buffer, pH 4.5). To be closer to in vivo application of liposomes and to achieve further improvement of their stability, liposomes were incorporated in vehicles suitable for vaginal self-administration. Gels of polyacrylate were chosen as vehicles for liposomal preparations. Due to their hydrophilic nature and bioadhesive properties, it was possible to achieve an adequate pH value corresponding to physiological conditions as well as desirable viscosity. In vitro release studies of liposomes incorporated in these gels (Carbopol 974P NF or Carbopol 980 NF) confirmed their applicability as a novel drug carrier system in vaginal delivery. Regardless of the gel used, even 24 h after the incubation of liposomal gel in the buffer pH 4.5 more than 80% of the originally entrapped substance was still retained. PMID:11337174

Will Preoperative Atrophy and Fatty Degeneration of the Shoulder Muscles Improve after Rotator Cuff Repair in Patients with Massive Rotator Cuff Tears?  

PubMed Central

Recently, retear rate after repair for massive cuff tear have been improved through devised suture techniques. However, reported retear rate is relevant to preoperative atrophy and fatty degeneration. The purpose of this study was to investigate whether preoperative atrophy and fatty degeneration of rotator cuff muscles improve by successful repair. Twenty-four patients with massive rotator cuff tear were evaluated on the recovery of atrophy and fatty degeneration of supraspinatus and infraspinatus muscle after surgery. Atrophy was classified by the occupation ratio and fatty degeneration by modified Goutallier's classification. Both were assessed on magnetic resonance imaging (MRI) before and after the operation. When the cuff was well repaired, improvement of the atrophy and fatty degeneration were observed in a half and a one-fourth of the cases, respectively. In retear cases, however, atrophy and fatty degeneration became worse. Improvement of atrophy and fatty degeneration of the rotator cuff muscles may be expected in the cases with successful achievement of rotator cuff repair for large and massive tear.

Contractile dysfunction of the shoulder (rotator cuff tendinopathy): an overview  

PubMed Central

It is now over a decade since the features defining a contractile dysfunction of the shoulder were first reported. Since this time, some progress has been made to better understand this mechanical syndrome. In response to these developments, this narrative review will explore current understanding in relation to pathology, diagnosis, treatment, and prognosis of this syndrome with reference to literature specifically relating to contractile dysfunction but also literature relating to rotator cuff tendinopathy where necessary. The review not only identifies the strengths of the mechanical diagnosis and therapy approach with reference to a contractile dysfunction of the shoulder but also identifies where further progress needs to be made.

Pulmonary Embolism after Arthroscopic Rotator Cuff Repair: A Case Report

Total hip/knee arthroplasty may cause venous thromboembolism (VTE) as a postoperative complication. However, there are few reports on VTE after arthroscopic shoulder surgery. We report a patient who developed pulmonary embolism (PE) 6 days after arthroscopic rotator cuff repair but recovered without sequelae. In this case, the possibility of DVT of the lower limbs was denied by contrast-enhanced CT. Most possibly, the source of PE was deep vein thrombosis (DVT) of the upper limb under Desault fixation which showed arthroscopic surgery-related swelling postoperatively.

Epidemiology, natural history, and indications for treatment of rotator cuff tears.  

PubMed

The etiology of rotator cuff disease is likely multifactorial, including age-related degeneration and microtrauma and macrotrauma. The incidence of rotator cuff tears increases with aging with more than half of individuals in their 80s having a rotator cuff tear. Smoking, hypercholesterolemia, and genetics have all been shown to influence the development of rotator cuff tearing. Substantial full-thickness rotator cuff tears, in general, progress and enlarge with time. Pain, or worsening pain, usually signals tear progression in both asymptomatic and symptomatic tears and should warrant further investigation if the tear is treated conservatively. Larger (>1-1.5 cm) symptomatic full-thickness cuff tears have a high rate of tear progression and, therefore, should be considered for earlier surgical repair in younger patients if the tear is reparable and there is limited muscle degeneration to avoid irreversible changes to the cuff, including tear enlargement and degenerative muscle changes. Smaller symptomatic full-thickness tears have been shown to have a slower rate of progression, similar to partial-thickness tears, and can be considered for initial nonoperative treatment due to the limited risk for rapid tear progression. In both small full-thickness tears and partial-thickness tears, increasing pain should alert physicians to obtain further imaging as it can signal tear progression. Natural history data, along with information on factors affecting healing after rotator cuff repair, can help guide surgeons in making appropriate decisions regarding the treatment of rotator cuff tears. The management of rotator cuff tears should be considered in the context of the risks and benefits of operative versus nonoperative treatment. Tear size and acuity, the presence of irreparable changes to the rotator cuff or glenohumeral joint, and patient age should all be considered in making this decision. Initial nonoperative care can be safely undertaken in older patients (>70 years old) with chronic tears; in patients with irreparable rotator cuff tears with irreversible changes, including significant atrophy and fatty infiltration, humeral head migration, and arthritis; in patients of any age with small (<1 cm) full-thickness tears; or in patients without a full-thickness tear. Early surgical treatment can be considered in significant (>1 cm-1.5 cm) acute tears or young patients with full-thickness tears who have a significant risk for the development of irreparable rotator cuff changes.

Benign vaginal polyp: a histological, histochemical and immunohistochemical study of 20 polyps with comparison to normal vaginal subepithelial layer.  

PubMed

Twenty benign vaginal polyps from 18 patients, together with sections from normal vaginal epithelium, were studied histologically, histochemically using elastic van Gieson stain and immunohistochemically using monoclonal antibodies against vimentin, desmin and actin. The striking finding was the similarity, both histologically and immunohistochemically, of the stroma of vaginal polyps to that of the loose subepithelial layer found in normal vagina. The important difference was the marked degeneration of the elastic tissue, increased number of stellate and giant fibroblasts and subepithelial condensation of fibroblasts in the polyps. These findings support the hypothesis that vaginal polyps may represent a reactive hyperplasia of the loose subepithelial zone of the vaginal wall. PMID:1302457

Improving photoacoustic imaging contrast of brachytherapy seeds  

NASA Astrophysics Data System (ADS)

Prostate brachytherapy is a form of radiotherapy for treating prostate cancer where the radiation sources are seeds inserted into the prostate. Accurate localization of seeds during prostate brachytherapy is essential to the success of intraoperative treatment planning. The current standard modality used in intraoperative seeds localization is transrectal ultrasound. Transrectal ultrasound, however, suffers in image quality due to several factors such speckle, shadowing, and off-axis seed orientation. Photoacoustic imaging, based on the photoacoustic phenomenon, is an emerging imaging modality. The contrast generating mechanism in photoacoustic imaging is optical absorption that is fundamentally different from conventional B-mode ultrasound which depicts changes in acoustic impedance. A photoacoustic imaging system is developed using a commercial ultrasound system. To improve imaging contrast and depth penetration, absorption enhancing coating is applied to the seeds. In comparison to bare seeds, approximately 18.5 dB increase in signal-to-noise ratio as well as a doubling of imaging depth are achieved. Our results demonstrate that the coating of the seeds can further improve the discernibility of the seeds.

Contemporary brachytherapy approaches in non-small-cell lung cancer.  

PubMed

Brachytherapy has the ability to deliver a higher tumor dose compared to external beam irradiation, while sparing normal tissue outside the tumor; it is the most effective means of delivering conformal radiation and can be tailored to clinical circumstances, either at open surgery or in an ambulatory setting, which is currently the preferred method. Intraoperative lung and/or endobronchial brachytherapy in the management of non-small-cell lung cancer offers a good curative potential in patients with accessible localized tumors, well defined and small to moderate in size, that have not metastasized to the lymph nodes and are technically or medically inoperable. Effective palliation can be frequently obtained by endobronchial brachytherapy on an outpatient procedure basis. Brachytherapy administered simultaneously with chemotherapy is better tolerated than a course of external beam irradiation and chemotherapy. PMID:9881944

Coregistered photoacoustic-ultrasound imaging applied to brachytherapy  

NASA Astrophysics Data System (ADS)

Brachytherapy is a form of radiation therapy commonly used in the treatment of prostate cancer wherein sustained radiation doses can be precisely targeted to the tumor area by the implantation of small radioactive seeds around the treatment area. Ultrasound is a popular imaging mode for seed implantation, but the seeds are difficult to distinguish from the tissue structure. In this work, we demonstrate the feasibility of photoacoustic imaging for identifying brachytherapy seeds in a tissue phantom, comparing the received intensity to endogenous contrast. We have found that photoacoustic imaging at 1064 nm can identify brachytherapy seeds uniquely at laser penetration depths of 5 cm in biological tissue at the ANSI limit for human exposure with a contrast-to-noise ratio of 26.5 dB. Our realtime combined photoacoustic-ultrasound imaging approach may be suitable for brachytherapy seed placement and post-placement verification, potentially allowing for realtime dosimetry assessment during implantation.

Interrater reproducibility of clinical tests for rotator cuff lesions  

PubMed Central

Background: Rotator cuff lesions are common in the community but reproducibility of tests for shoulder assessment has not been adequately appraised and there is no uniform approach to their use. Objective: To study interrater reproducibility of standard tests for shoulder evaluation among a rheumatology specialist, rheumatology trainee, and research nurse. Methods: 136 patients were reviewed over 12 months at a major teaching hospital. The three assessors examined each patient in random order and were unaware of each other's evaluation. Each shoulder was examined in a standard manner by recognised tests for specific lesions and a diagnostic algorithm was used. Between-observer agreement was determined by calculating Cohen's ? coefficients (measuring agreement beyond that expected by chance). Results: Fair to substantial agreement was obtained for the observations of tenderness, painful arc, and external rotation. Tests for supraspinatus and subscapularis also showed at least fair agreement between observers. 40/55 (73%) ? coefficient assessments were rated at >0.2, indicating at least fair concordance between observers; 21/55 (38%) were rated at >0.4, indicating at least moderate concordance between observers. Conclusion: The reproducibility of certain tests, employed by observers of varying experience, in the assessment of the rotator cuff and general shoulder disease was determined. This has implications for delegation of shoulder assessment to nurse specialists, the development of a simplified evaluation schedule for general practitioners, and uniformity in epidemiological research studies.

Surgical treatment of tears of the rotator cuff in athletes.  

PubMed

Forty-five athletes with either a partial or a complete tear of the rotator cuff were treated with anterior acromioplasty and repair of the tear. The minimum duration of follow-up was twenty-four months (average, forty-two months). Thirty patients had an incomplete tear and fifteen had a complete tear. Postoperatively, thirty-nine (87 per cent) of the patients stated that they were improved compared with their preoperative status, although only thirty-four patients (76 per cent) felt that they had a significant reduction of pain postoperatively. Objectively, twenty-five (56 per cent) of the patients were rated as having a good result, which allowed them to return to their former competitive level without significant pain. Twelve (41 per cent) of the twenty-nine athletes who had been involved in pitching and throwing returned to their former competitive status. Seven (32 per cent) of the twenty-two pitchers and throwers who had been active at a professional or collegiate level returned to the same competitive level. In our experience, a repair of the rotator cuff combined with an acromioplasty in a young athletic population provides satisfactory relief of pain but does not guarantee that the patient will be able to return to his or her former competitive status in all sports.

Rotator cuff injuries in baseball. Prevention and rehabilitation.  

PubMed

Rotator cuff and ligamentous capsule injuries are common in the young baseball player. In order to understand these injuries, it is important to first appreciate the delicate balance between shoulder mobility and stability as well as the biomechanics of throwing. This background information makes it easy to see how shoulder injuries are really part of a progressive continuum beginning with instability leading to subluxation, and later impingement which can result in a rotator cuff tear. A detailed and precise history and physical is crucial in determining where a patient might be on the continuum. An accurate evaluation will also help appropriately place a patient in one of the following 4 groups: pure impingement, anterior instability due to trauma with secondary impingement, anterior stability due to a hyperelasticity with secondary impingement, and pure anterior instability. A kinesiological repair is the initial treatment of choice. It is the best preventative or early treatment available, and consists of a specific strengthening programme. If this fails (as in only 5 to 10% of the cases), an anatomical repair is instituted. There are 4 basic guidelines when doing this surgery: (a) maintain muscle attachments and proprioceptive fibres; (b) do not shorten the capsule significantly; (c) build up the anterior labrum; and (d) regain full range of motion quickly through abduction splinting and rehabilitation. A postoperative rehabilitation programme is then diligently adhered to, as it is at least as important as the surgery itself. PMID:3231953

Effect of rotator cuff pathology on shoulder rhythm.  

PubMed

The purpose of this study was to test the hypothesis that shoulder rhythm is affected by rotator cuff pathology during arm elevation. We divided 42 subjects into 3 groups: those with full-thickness rotator cuff tears (RCTs) (n = 14), those with tendinopathy (n = 13), and control subjects (n = 15). Shoulder kinematics was recorded while subjects performed elevation in the sagittal and scapular planes. Euler angles were computed for scapular and humeral elevation. Data were divided into 3 equal phases. Lines were fit and the slope determined for each phase. Significant differences in slopes ( P < .05) were found between experimental groups for both motions. The RCT group had higher slopes in the initial and middle phases for sagittal elevation and in the middle phase for scapular abduction. The scapula was elevated more in the RCT group in the initial two thirds of movement. This motion may change the length of remaining muscles so that they operate on a more effective part of their length-tension curve. PMID:15726088

Bipolar hemiarthroplasty for chronic rotator cuff tear arthropathy.  

PubMed

Massive rotator cuff tears associated with glenohumeral arthritis are currently an unsolvable clinical entity. We review our series of 14 patients with rotator cuff tear arthropathy (RCTA) who underwent a bipolar prosthesis of the shoulder. The average follow up was 27.8 months (range, 24-48 months), and the average age was 71 years (range, 57-84 years). Of these 14 patients, 9 were men and 5 women. None of these patients had undergone previous shoulder surgery, and all patients underwent conservative treatment that failed to improve their symptoms or range of motion. Preoperatively, the average active forward flexion was 30 degrees, active external rotation was 10 degrees, and the American Shoulder and Elbow Society (ASES) score was 25 points. Postoperatively, the average active forward flexion improved to 88 degrees, active external rotation increased to 37 degrees, and the ASES score improved to 80 points. Of the 14 patients, 12 stated that they had no pain with activities of daily living. Two patients continued to have moderate pain in everyday activity. PMID:12629606

Robotic-Assisted Laparoscopic Nephroureterectomy and Bladder Cuff Excision  

PubMed Central

Background and Objectives: Our aim was to show that bladder cuff excision and distal ureterectomy can be safely performed by using the LigaSure device during robotic-assisted laparoscopic nephroureterectomy. Methods: A 60-year-old man presented with gross hematuria. He was diagnosed with upper urinary tract transitional cell carcinoma (TCC) on the left side and was scheduled for robot-assisted laparoscopic surgery. Without changing the patient's position, sealing with the LigaSure atlas for bladder cuff excision and distal ureterectomy was performed. Results: The operating time was 140 minutes from the initial incision to skin closure of all incisions. The estimated blood loss during the surgery was 120mL. There were no intraoperative or postoperative complications. The Foley drain was removed on day 3 after normal cystographic findings, and the patient was discharged from the hospital on the fourth postoperative day. Conclusion: Robot-assisted nephroureterectomy with distal ureterectomy in the same position using a LigaSure device is a safe alternative for upper tract transitional cell carcinoma.

Arthroscopic technique for patch augmentation of rotator cuff repairs.  

PubMed

The patient is placed in the lateral position, and an arthroscopic cuff repair is performed according to standard techniques. The line of repair is usually in the shape of a "T" or an "L." The repair is viewed through the lateral portal, with fluid inflow through the scope. Mattress sutures are placed in the anterior and posterior portions of the cuff, with respect to the line of repair, just medial to the most medial point of the tear. The sutures are placed in accordance with margin convergence suture passing methods. Next, 2 double-stranded suture anchors are placed into the lateral aspect of the greater tuberosity, which can be used to secure the anterior and posterior portions of the rotator cuff as well as the patch. The cuff sutures are tied first; then, the patch is addressed. The graft is sized by placement of a ruled probe or similar device into the subacromial space. The length of each side of the "rectangle" is measured to obtain the dimensions of the patch. The patch is then cut to fit the measurements. If the patch material is elastic, a slightly smaller than measured graft is cut to provide tension on the repair. The arthroscope is then moved to the posterior portal, and a large (8 mm) cannula, with a dam, is placed into the lateral portal. All sutures are brought out of the lateral cannula, and corresponding ends of each suture are held together in a clamp. The sutures are placed in their respective orientations once outside the cannula (e.g., anterior-medial, anterior-lateral), covering all 4 quadrants. Care is taken to ensure that the sutures have no twists and are not wrapped around one another. The sutures are passed through the graft, in mattress fashion, with a free needle, in their respective corners and clamped again. The graft is then grasped with a small locking grasper on its medial edge and is passed through the cannula into the subacromial space. The clamps holding the sutures are then gently pulled to remove the slack. A smaller (5 mm) cannula is placed through 1 of the anchor incisions into the subacromial space. The medial 2 sutures are retrieved, a pair at a time, through the small cannula and are tied according to standard arthroscopic techniques; then, the lateral 2 sutures are retrieved from the anchor. The graft should cover the area of repair completely and should be under slight tension. Additional sutures may be placed to further secure or tension the graft as necessary, with the use of standard suture passing techniques, similar to those used when margin convergence is performed. Passive shoulder motion, pendulum exercises, and active elbow and wrist motion begin 2 days after surgery when the dressing is removed. Active assisted motion and active motion begin at 6 weeks, with integrated periscapular stabilization exercises. Formal cuff strengthening begins no sooner than 12 weeks after surgery for large and massive tears. PMID:17027416

HDR intraluminal brachytherapy in the treatment of malignant bronchial obstructions.  

PubMed

Symptomatology of malignant intrabronchial obstructions has a serious negative effect on the quality of patients' life. Intrabronchial brachytherapy can play an important role in the palliation of these symptoms. Between December 1996 and September 1998 48 patients suffering from malignant intrabronchial obstructions were treated with intraluminal brachytherapy in the Dept. of Radiation Oncology at the University Maternity Hospital in Brno. Gammamed HDR automatical afterloading equipment was used to treat all patients. The first group (23 patients) was treated with a combination of intraluminal brachytherapy and external radiotherapy. The second group (18 patients who had relapsed after previous external radiotherapy) was given intraluminal radiotherapy only. A third group (7 patients) underwent intraluminal brachytherapy only. In the first group 17 patients (77%) showed symptomatic relief with tumor regression on X-ray in 16 patients and with bronchoscopic regression in 19 patients. Seven patients died before October 1998 having survived 1-6 months after the first brachytherapy application. Sixteen patients are still alive (1-14 months). In the second group, 10 patients (56%) reported significant improvement of symptoms, with endoscopic regression in 12 patients. Twelve patients died before October 1998 surviving 1-6 months after the first brachytherapy session, 6 patients are still alive 1-5 months after the first brachytherapy fraction. In the third group, bronchoscopy confirmed a complete disappearance of intrabronchial lesion in two cases with early intrabronchial tumor. Five patients reported symptomatic improvement with endoscopic regression of the tumor. There was only one complication recorded: bronchospasm in one patient. The short follow up and limited number of patients does not allow comment on the late effects and survival, yet. In conclusion, intraluminal brachytherapy is an effective and safe approach for palliation of malignant bronchial obstructions. PMID:10870688

[Radiotherapy of primary vaginal carcinoma and effects of histological and clinical factors on the prognosis].  

PubMed

434 cases of primary vaginal carcinoma were treated from 1950 to 1984 at the Irradiation Department of the University Clinic for Obstetrics and Gynecology, Vienna. The five-year survival rate for various clinical stages is as follows: Stage I 76.7%, stage II 44.5%, stage III 31%, stage IV 18.2%. In this retrospective study 110 patients seen from 1975 to 1984 were reviewed in detail and evaluated with a view toward their clinical and morphological aspects and survival rates. Patients up to the age of 60 have a five-year survival rate of 50%, those over 75 years of age reach only 34.3%. If the carcinoma was discovered in a routine check up the survival rate is 61.1%, whereas in cases with symptoms the rate decreases to 36.9%. Survival differences were also observed for patients with a carcinoma in the upper third of the vagina (61.1%) versus patients with a carcinoma in the lower third (33.3%); for patients with well-differentiated tumours (62.5%) versus patients with grades II and III (41.5% and 34.9%). It can be seen, that with brachytherapy local control of the carcinoma can be achieved with excellent results in early stages. Treatment of patients with more advanced carcinomas should include external beam therapy. The importance of gynecological screening especially for older women is emphasized. PMID:1992537

Association between atopy and recurrent vaginal candidiasis  

PubMed Central

To determine whether there is an association between atopy and recurrent vaginal candidiasis (RVC) and to evaluate the type-2 immune response in patients with RVC. Evaluation of immediate hypersensitivity skin tests to aeroallergens, measurement of total IgE and Candida albicans specific IgE and levels of IL-5 in 44 women with RVC and 26 with sporadic vaginal candidiasis (SVC). Statistical analyses were performed by Mann–Whitney test and ?2 test with Yates correction. History of atopy (68%) and positive skin test (42%) were higher (P < 0·05) in RVC than in patients with SVC. No significant difference was found in total IgE, C. albicans specific IgE and IL-5 levels. There was a strong association between atopy and RVC, but type-2 immune response to C. albicans antigen was absent or similar in the two groups of patients.

Cytolytic vaginosis: misdiagnosed as candidal vaginitis.  

PubMed Central

OBJECTIVES: In this study, 210 women with vaginal discharge and other symptoms/signs of genital pathology suggestive of vulvovaginal candidiasis (VVC) were involved in order to distinguish true WC and cytolytic vaginosis (CV) cases. METHODS: Fungal cultures, 10% potassium hydroxide (KOH) and Gram stained preparations and pH measurements were performed on the vaginal discharge material of each patient. RESULTS: Fifteen patients (7.1%) were diagnosed with cytolytic vaginosis according to their clinical and microbiological findings, including abundant lactobacilli, fragmented epithelial cells and/or free nuclei due to cytolysis, seen in their discharge materials on microscopic examination, but no fungal growth. CONCLUSIONS: The results of this study may contribute to the reports in the literature indicating the importance of such disorders, which are generally misdiagnosed as candidiasis.

Murine Models of Vaginal Trichomonad Infections  

PubMed Central

Trichomonas vaginalis and Tritrichomonas foetus cause common sexually transmitted infections in humans and cattle, respectively. Mouse models of trichomoniasis are important for pathogenic and therapeutic studies. Here, we compared murine genital infections with T. vaginalis and T. foetus. Persistent vaginal infection with T. foetus was established with 100 parasites but T. vaginalis infection required doses of 106, perhaps because of greater susceptibility to killing by mouse vaginal polymorphonuclear leukocytes. Infection with T. vaginalis persisted longest after combined treatment of mice with estrogen and dexamethasone, whereas infection was only short-lived when mice were given estrogen or dexamethasone alone, co-infected with Lactobacillus acidophilus, and/or pretreated with antibiotics. Infection rates were similar with metronidazole-resistant (MR) and metronidazole-sensitive (MS) T. vaginalis. High dose but not low dose metronidazole treatment controlled infection with MS better than MR T. vaginalis. These murine models will be valuable for investigating the pathogenesis and treatment of trichomoniasis.

Probiotic and prebiotic applications for vaginal health.  

PubMed

Infections of the urogenital tract in women are extremely common, and there is no evidence of a reduction in incidence. Treatment and preventive strategies have been relatively unchanged for 50 years. The concept of using probiotic lactobacilli or prebiotics that stimulate the growth of protective organisms emerged in the mid-1980s and has led to several strains being tested successfully in women. With the advent of genomic profiling of the healthy vaginal microbiota, an improved understanding of metabolic systems within lactobacilli, and the ability to deliver products in food and supplement forms, the future should see new ways for women to restore and maintain their vaginal health, without the side effects of pharmaceutical agents. Indeed, studies indicate that probiotics can be taken in conjunction with the antibiotics and antifungal agents used to eradicate infections. In the future, probiotics and prebiotics will represent an important adjunct to pharmaceutical and other approaches used to care for feminine health. PMID:22468339

Trial of vaginal breech delivery: current role.  

PubMed

Breech presentation occurs at term in approximately 3% to 4% of singleton gestations. This presentation is associated with a variety of maternal and fetal conditions including preterm labor, abnormal amniotic fluid volume, hydrocephaly, anencephaly, mullerian anomalies, abnormal placentation, and multifetal gestation. Cesarean delivery has been associated with increased risk of subsequent accreta, placenta previa, hemorrhage, and hysterectomy. The Term Breech Trial initially suggested that planned vaginal breech delivery is associated with increased neonatal morbidity and mortality compared with planned cesarean delivery. Long-term follow-up of these vaginally delivered infants contradict the initial findings. Current debate surrounds the dilemma of whether the untoward complications of cesarean delivery are warranted given uncertain minimal increases in neonatal survival and improvement in neurologic outcome with planned cesarean.

Four cases of vaginal metastases of renal carcinoma are reported. This is an incidence of 1.3% in 313 operated patients (from 1/1/70 to 12/31/76). A surgical treatment of primary renal carcinoma and vaginal metastasis seems to be reasonable in there cases. Since in accordance with the literature metastatic involvement of vagina and vulva seems not to be a very rare finding, the diagnostic in renal carcinoma should imply a gynecologic examination. Although in carcinoma of the left kidney metastatic spreading into the external female genitalia most probably occurs by a retrograde venous pathway (left ovarian vein), the way of dissemination in carcinoma of the right side is unclear.

Can group B streptococci cause symptomatic vaginitis?  

PubMed Central

BACKGROUND: Maternal cervicovaginal colonization with Lancefield group B streptococci (GBS) is an important risk factor for neonatal morbidity and mortality. About 15% of women are carriers of GBS. Usually, they are asymptomatic. CASES: We describe two patients with symptomatic vaginitis for which no apparent cause was found. Both patients were heavily colonized with GBS. After antibiotic treatment, both became asymptomatic and culture negative, but after recolonization with GBS, symptoms resumed. This phenomenon was repeatedly observed. After emergence of resistance to antibiotics, local application of chlorhexidine appeared to be the only useful treatment. CONCLUSION: We hypothesize that GBS-vaginitis may be a possible disease entity. Although at present it is not clear why some patients become symptomatic, we speculate that the immunologic response is somehow selectively hampered in such patients.

Purpose To understand racial/ethnic minority adolescent females’ experiences with the vaginal ring. Methods We conducted in-depth interviews with a clinic-based sample of 32 young women aged 15–24 years who had used the vaginal ring. Results Qualitative analysis using grounded theory revealed that adolescents undergo a multi-stage process when trying the ring and adopting ring use. These stages include hearing about the ring, initial reactions, first experiences with insertion and removal, and first sexual experiences. Adolescents subsequently enter an assessment and adjustment stage in which they decide whether to adopt or discontinue ring use. Ultimately they share their experiences with friends. Conclusions The model developed provides a context within which providers may advise adolescents as they begin use of the ring. Some specific recommendations are offered.

Development and evaluation of acid-buffering bioadhesive vaginal tablet for mixed vaginal infections.  

PubMed

An acid-buffering bioadhesive vaginal tablet was developed for the treatment of genitourinary tract infections. From the bioadhesion experiment and release studies it was found that polycarbophil and sodium carboxymethylcellulose is a good combination for an acid-buffering bioadhesive vaginal tablet. Sodium monocitrate was used as a buffering agent to provide acidic pH (4.4), which is an attribute of a healthy vagina. The effervescent mixture (citric acid and sodium bicarbonate) along with a superdisintegrant (Ac-Di-sol) was used to enhance the swellability of the bioadhesive tablet. The drugs clotrimazole (antifungal) and metronidazole (antiprotozoal as well as an antibacterial) were used in the formulation along with Lactobacillus acidophilus spores to treat mixed vaginal infections. From the ex vivo retention study it was found that the bioadhesive polymers hold the tablet for more than 24 hours inside the vaginal tube. The hardness of the acid-buffering bioadhesive vaginal tablet was optimized, at 4 to 5 kg hardness the swelling was found to be good and the cumulative release profile of the developed tablet was matched with a marketed conventional tablet (Infa-V). The in vitro spreadability of the swelled tablet was comparable to the marketed gel. In the in vitro antimicrobial study it was found that the acid-buffering bioadhesive tablet produces better antimicrobial action than marketed intravaginal drug delivery systems (Infa-V, Candid-V and Canesten 1).

Predictors of Metastatic Disease After Prostate Brachytherapy  

SciTech Connect

Purpose: To identify predictors of metastatic disease after brachytherapy treatment for prostate cancer. Methods and Materials: All patients who received either brachytherapy alone (implant) or brachytherapy in combination with external beam radiation therapy for treatment of localized prostate cancer at The Mount Sinai Hospital between June 1990 and March 2007 with a minimum follow-up of 2 years were included. Univariate and multivariable analyses were performed on the following variables: risk group, Gleason score (GS), clinical T stage, pretreatment prostate-specific antigen level, post-treatment prostate-specific antigen doubling time (PSA-DT), treatment type (implant vs. implant plus external beam radiation therapy), treatment era, total biological effective dose, use of androgen deprivation therapy, age at diagnosis, and race. PSA-DT was analyzed in the following ordinate groups: 0 to 90 days, 91 to 180 days, 180 to 360 days, and greater than 360 days. Results: We included 1,887 patients in this study. Metastases developed in 47 of these patients. The 10-year freedom from distant metastasis (FFDM) rate for the entire population was 95.1%. Median follow-up was 6 years (range, 2-15 years). The only two significant predictors of metastatic disease by multivariable analyses were GS and PSA-DT (p < 0.001 for both variables). Estimated 10-year FFDM rates for GS of 6 or less, GS of 7, and GS of 8 or greater were 97.9%, 94.3%, and 76.1%, respectively (p < 0.001). Estimated FFDM rates for PSA-DT of 0 to 90 days, 91 to 180 days, 181 to 360 days, and greater than 360 days were 17.5%, 67.9%, 74%, and 94.8%, respectively (p < 0.001). Estimated 10-year FFDM rates for the low-, intermediate-, and high-risk groups were 98.6%, 96.2%, and 86.7%, respectively. A demographic shift to patients presenting with higher-grade disease in more recent years was observed. Conclusions: GS and post-treatment PSA-DT are both statistically significant independent predictors of metastatic disease. Patients with a high GS and/or short PSA-DT have a higher likelihood of developing metastatic disease and should be considered for systemic therapy.

VARIATION AND PREDICTORS OF VAGINAL DOUCHING BEHAVIOR  

PubMed Central

Introduction Vaginal douching is a widespread practice among American women. Little research has been done examining variation in the practice or identifying risk factors. Methods We collected data on douching, as well as hypothesized predictors of vaginal douching, as part of a cohort study on preterm birth. African-American women residing in Baltimore City, Maryland, were enrolled if they received prenatal care or delivered at The Johns Hopkins Medical Institution. Interview data were collected on 872 women between March 2001 and July 2004, with a response rate of 68%. Logistic regression analysis was selected to identify factors associated with douching in the 6 months prior to pregnancy. Results Almost two thirds of women reported ever douching and more than two thirds of those women reported douching in the 6 months prior to pregnancy. Variation was seen in the practice of douching with regard to frequency as well as technique. After adjusting for several confounders, prenatal enrollment (odds ratio [OR], 1.80; 95% confidence interval [CI], 1.29, 2.53), more unmet needs for time for “nonessentials” (OR, 1.83; 95% CI, 1.27, 2.63), smoking in the year prior to the birth (OR, 1.78; 95% CI, 1.22, 2.60), and age > 19 years (OR, 2.60; 95% CI, 1.36, 4.97) were significant predictors of douching in the 6 months prior to pregnancy. Discussion We identified considerable heterogeneity in the practice of vaginal douching in a cohort of low income African-American women. Conclusions Future studies should incorporate measures of the predictors of douching and detailed exposure information to determine the independent contribution of vaginal douching to health outcomes.

Vernix Caseosa Peritonitis After Vaginal Delivery  

PubMed Central

Introduction Vernix caseosa peritonitis (VCP) is a very unusual complication caused by inflammatory response to amniotic fluid spilled into the maternal peritoneal cavity. Twenty-seven cases have been reported, and all occurred after cesarean section. Case presentation We present a case of VCP following vaginal delivery; this may be the first case reported after vaginal delivery. Mrs. A, 28 years old, gravida 3, para 2, with one previous cesarean section, was admitted at 41 weeks gestation in active labor. Vacuum extraction was performed to deliver a healthy male baby, 4.410 kg, Apgar scores 7, 8. She developed fever, acute abdominal pain, and distension about 3 hours after delivery. A diagnosis of acute abdomen was made. Laparotomy was performed and it revealed neither uterine scar rupture nor other surgical emergencies, but 500 mL of turbid fluid and some cheesy material on the serosal surface of all viscera. Biopsies were taken. She had a course of antibiotics and her recovery was complete. Histology of the peritoneal fluid and tissue biopsy resulted in a diagnosis of VCP. Conclusion Clinical diagnosis of peritonitis due to vernix caseosa should be considered in patients presenting postpartum with an acute abdomen after vaginal delivery.

Strength after surgical repair of the rotator cuff.  

PubMed

Forty-two consecutive patients (20 men and 22 women, age range 39 to 78 years) with full-thickness rotator cuff tears underwent a comprehensive isokinetic strength assessment before and at 3-month intervals for 1 year after surgery. All patients underwent acromioplasty and rotator cuff repair and were treated with a standardized postoperative rehabilitation program. Isokinetic strength testing was performed in flexion/extension, abduction/adduction, and external/internal rotation at 60 degrees/sec. The unaffected contralateral shoulder was tested for comparison. Clinical outcomes were assessed with the University of California Los Angeles Shoulder Rating Scale (maximum = 35 points). The average University of California Los Angeles score was 31.2 by 1 year after operation. Patients with small and medium tears had an average rating of 33.5, whereas those with large and massive tears had an average score of 28.3. Strength increased gradually during the first postoperative year. The preoperative mean peak torque was 54%, 45%, and 64% of the uninvolved shoulder in flexion, abduction, and external rotation, respectively; after operation it increased to 78%, 80%, and 79% by 6 months and 84%, 90%, and 91% by 12 months. The greatest improvement in strength consistently occurred during the first 6 months after surgery. Patients also showed marked increases in both work and power. By 12 months after operation mean work had increased to 70% in flexion and abduction and 90% in external rotation of the uninvolved shoulder. Similarly, mean power had increased to 68%, 79%, and 90% of the uninvolved shoulder in flexion, abduction, and external rotation, respectively, by 12 months after operation. Recovery of strength correlated primarily with the size of the tear: for small and medium tears recovery of strength was almost complete during the first year, and for large and massive tears it was much slower and less consistent. By using isokinetic strength evaluation we found that recovery of strength after rotator cuff repair requires at least 1 year of rehabilitation. PMID:8919437

Vaginal route: a gynaecological route for much more than hysterectomy.  

PubMed

Vaginal hysterectomy is the method of choice for gynaecologists who carry out hysterectomies. Undertaking this procedure regularly will enhance the gynaecologist's level of skill and enable conditions such as ovarian cysts, broad ligament fibroids and other adnexal pathology to be dealt with vaginally during hysterectomy surgery without abdominal invasion. It is also important as the vaginal route allows access to the posterior cul-de-sac, which can facilitate surgery or offer an alternative route to achieving the desired outcome. In this chapter, we look at the main indications for vaginal surgery, and also at other conditions in which vaginal surgery may be suitable (e.g. benign and malignant conditions). We believe that gynaecologists who include vaginal surgery in their armamentarium are better equipped to serve their patients. PMID:21349773

Harmony search optimization for HDR prostate brachytherapy  

NASA Astrophysics Data System (ADS)

In high dose-rate (HDR) prostate brachytherapy, multiple catheters are inserted interstitially into the target volume. The process of treating the prostate involves calculating and determining the best dose distribution to the target and organs-at-risk by means of optimizing the time that the radioactive source dwells at specified positions within the catheters. It is the goal of this work to investigate the use of a new optimization algorithm, known as Harmony Search, in order to optimize dwell times for HDR prostate brachytherapy. The new algorithm was tested on 9 different patients and also compared with the genetic algorithm. Simulations were performed to determine the optimal value of the Harmony Search parameters. Finally, multithreading of the simulation was examined to determine potential benefits. First, a simulation environment was created using the Python programming language and the wxPython graphical interface toolkit, which was necessary to run repeated optimizations. DICOM RT data from Varian BrachyVision was parsed and used to obtain patient anatomy and HDR catheter information. Once the structures were indexed, the volume of each structure was determined and compared to the original volume calculated in BrachyVision for validation. Dose was calculated using the AAPM TG-43 point source model of the GammaMed 192Ir HDR source and was validated against Varian BrachyVision. A DVH-based objective function was created and used for the optimization simulation. Harmony Search and the genetic algorithm were implemented as optimization algorithms for the simulation and were compared against each other. The optimal values for Harmony Search parameters (Harmony Memory Size [HMS], Harmony Memory Considering Rate [HMCR], and Pitch Adjusting Rate [PAR]) were also determined. Lastly, the simulation was modified to use multiple threads of execution in order to achieve faster computational times. Experimental results show that the volume calculation that was implemented in this thesis was within 2% of the values computed by Varian BrachyVision for the prostate, within 3% for the rectum and bladder and 6% for the urethra. The calculation of dose compared to BrachyVision was determined to be different by only 0.38%. Isodose curves were also generated and were found to be similar to BrachyVision. The comparison between Harmony Search and genetic algorithm showed that Harmony Search was over 4 times faster when compared over multiple data sets. The optimal Harmony Memory Size was found to be 5 or lower; the Harmony Memory Considering Rate was determined to be 0.95, and the Pitch Adjusting Rate was found to be 0.9. Ultimately, the effect of multithreading showed that as intensive computations such as optimization and dose calculation are involved, the threads of execution scale with the number of processors, achieving a speed increase proportional to the number of processor cores. In conclusion, this work showed that Harmony Search is a viable alternative to existing algorithms for use in HDR prostate brachytherapy optimization. Coupled with the optimal parameters for the algorithm and a multithreaded simulation, this combination has the capability to significantly decrease the time spent on minimizing optimization problems in the clinic that are time intensive, such as brachytherapy, IMRT and beam angle optimization.

A dynamic dosimetry system for prostate brachytherapy  

NASA Astrophysics Data System (ADS)

The lack of dynamic dosimetry tools for permanent prostate brachytherapy causes otherwise avoidable problems in prostate cancer patient care. The goal of this work is to satisfy this need in a readily adoptable manner. Using the ubiquitous ultrasound scanner and mobile non-isocentric C-arm, we show that dynamic dosimetry is now possible with only the addition of an arbitrarily configured marker-based fiducial. Not only is the system easily configured from accessible hardware, but it is also simple and convenient, requiring little training from technicians. Furthermore, the proposed system is built upon robust algorithms of seed segmentation, fiducial detection, seed reconstruction, and image registration. All individual steps of the pipeline have been thoroughly tested, and the system as a whole has been validated on a study of 25 patients. The system has shown excellent results of accurately computing dose, and does so with minimal manual intervention, therefore showing promise for widespread adoption of dynamic dosimetry.

Automatic Brachytherapy Seed Placement Under MRI Guidance  

PubMed Central

The paper presents a robotic method of performing low dose rate prostate brachytherapy under magnetic resonance imaging (MRI) guidance. The design and operation of a fully automated MR compatible seed injector is presented. This is used with the MrBot robot for transperineal percutaneous prostate access. A new image-registration marker and algorithms are also presented. The system is integrated and tested with a 3T MRI scanner. Tests compare three different registration methods, assess the precision of performing automated seed deployment, and use the seeds to assess the accuracy of needle targeting under image guidance. Under the ideal conditions of the in vitro experiments, results show outstanding image-guided needle and seed placement accuracy.

Photoacoustic imaging of prostate brachytherapy seeds  

PubMed Central

Brachytherapy seed therapy is an increasingly common way to treat prostate cancer through localized radiation. The current standard of care relies on transrectal ultrasound (TRUS) for imaging guidance during the seed placement procedure. As visualization of individual metallic seeds tends to be difficult or inaccurate under TRUS guidance, guide needles are generally tracked to infer seed placement. In an effort to improve seed visualization and placement accuracy, the use of photoacoustic (PA) imaging, which is highly sensitive to metallic objects in soft tissue, was investigated for this clinical application. The PA imaging properties of bare (i.e., embedded in pure gelatin) and tissue-embedded (at depths of up to 13 mm) seeds were investigated with a multi-wavelength (750 to 1090 nm) PA imaging technique. Results indicate that, much like ultrasonic (US) imaging, an angular dependence (i.e., seed orientation relative to imaging transducer) of the PA signal exists. Despite this shortcoming, however, PA imaging offers improved contrast, over US imaging, of a seed in prostate tissue if sufficient local fluence is achieved. Additionally, although the PA signal of a bare seed is greatest for lower laser wavelengths (e.g., 750 nm), the scattering that results from tissue tends to favor the use of higher wavelengths (e.g., 1064 nm, which is the primary wavelength of Nd:YAG lasers) when the seed is located in tissue. A combined PA and US imaging approach (i.e., PAUS imaging) shows strong potential to visualize both the seed and the surrounding anatomical environment of the prostate during brachytherapy seed placement procedures.

Calibration of Photon Sources for Brachytherapy  

NASA Astrophysics Data System (ADS)

Source calibration has to be considered an essential part of the quality assurance program in a brachytherapy department. Not only it will ensure that the source strength value used for dose calculation agrees within some predetermined limits to the value stated on the source certificate, but also it will ensure traceability to international standards. At present calibration is most often still given in terms of reference air kerma rate, although calibration in terms of absorbed dose to water would be closer to the users interest. It can be expected that in a near future several standard laboratories will be able to offer this latter service, and dosimetry protocols will have to be adapted in this way. In-air measurement using ionization chambers (e.g. a Baldwin—Farmer ionization chamber for 192Ir high dose rate HDR or pulsed dose rate PDR sources) is still considered the method of choice for high energy source calibration, but because of their ease of use and reliability well type chambers are becoming more popular and are nowadays often recommended as the standard equipment. For low energy sources well type chambers are in practice the only equipment available for calibration. Care should be taken that the chamber is calibrated at the standard laboratory for the same source type and model as used in the clinic, and using the same measurement conditions and setup. Several standard laboratories have difficulties to provide these calibration facilities, especially for the low energy seed sources (125I and 103Pd). Should a user not be able to obtain properly calibrated equipment to verify the brachytherapy sources used in his department, then at least for sources that are replaced on a regular basis, a consistency check program should be set up to ensure a minimal level of quality control before these sources are used for patient treatment.

Management of degenerative rotator cuff tears: a review and treatment strategy  

PubMed Central

The aim of this review was to present an over view of degenerative rotator cuff tears and a suggested management protocol based upon current evidence. Degenerative rotator cuff tears are common and are a major cause of pain and shoulder dysfunction. The management of these tears is controversial, as to whether they should be managed non-operatively or operatively. In addition when operative intervention is undertaken, there is question as to what technique of repair should be used. This review describes the epidemiology and natural history of degenerative rotator cuff tears. The management options, and the evidence to support these, are reviewed. We also present our preferred management protocol and method, if applicable, for surgical fixation of degenerative rotator cuff tears.

Relationship between lactobacilli and opportunistic bacterial pathogens associated with vaginitis  

PubMed Central

Background: Vaginitis, is an infectious inflammation of the vaginal mucosa, which sometimes involves the vulva. The balance of the vaginal flora is maintained by the Lactobacilli and its protective and probiotic role in treating and preventing vaginal infection by producing antagonizing compounds which are regarded as safe for humans. Aim: The aim of this study was to evaluate the protective role of Lactobacilli against common bacterial opportunistic pathogens in vaginitis and study the effects of some antibiotics on Lactobacilli isolates. Materials and Methods: In this study (110) vaginal swabs were obtained from women suffering from vaginitis who admitted to Babylon Hospital of Maternity and Paediatrics in Babylon province, Iraq. The study involved the role of intrauterine device among married women with vaginitis and also involved isolation of opportunistic bacterial isolates among pregnant and non pregnant women. This study also involved studying probiotic role of Lactobacilli by production of some defense factors like hydrogen peroxide, bacteriocin, and lactic acid. Results: Results revealed that a total of 130 bacterial isolates were obtained. Intrauterine device was a predisposing factor for vaginitis. The most common opportunistic bacterial isolates were Staphylococcus aureus, Escherichia coli, Streptococcus agalactiae, and Klebsiella pneumoniae. All Lactobacilli were hydrogen peroxide producers while some isolates were bacteriocin producers that inhibited some of opportunistic pathogens (S. aureus, E. coli). Lactobacilli were sensitive to erythromycin while 93.3% of them were resistant to ciprofloxacin and (40%, 53.3%) of them were resistant to amoxicillin and gentamycin respectively. Results revealed that there was an inverse relationship between Lactobacilli presence and organisms causing vaginitis. This may be attributed to the production of defense factors by Lactobacilli. Conclusion: The types of antibiotics used to treat vaginitis must be very selective in order not to kill the beneficial bacteria (Lactobacilli) that help in preservation of vaginal health and ecosystem as being one of the probiotic bacteria.

Recovery of neural activity from nerve cuff electrodes.  

PubMed

The ability to recover signals from the peripheral nerves would provide natural and physiological signals for controlling artificial limbs and neural prosthetic devices. Current cuff electrode systems can provide multiple channels but the signals have low signal to noise ratio and are difficult to recover. Previous work has shown that beamforming algorithms provide a method to extract such signals from peripheral nerve activiy [1]. This paper describes in-silico and in vivo experiments done to validate that method in a more realistic case. A modified beam forming algorithm capable of significantly decrease cross talk between channels is described and the results of the a 16-channel Flat Interface Nerve Electrode used to recover signals from the sciatic nerve in rabbit while the distal tibial and peroneal branches were stimulated The beamforming spatial filters were able to distinguish which branch was being stimulated, and in many cases how strongly, over a large range of stimulation intensities.

Factors that impact rehabilitation strategies after rotator cuff repair.  

PubMed

Multiple factors influence rehabilitation strategies after rotator cuff repair. These variables may also impact the overall success of the surgical intervention. Physicians and rehabilitation specialists should be aware of prognostic indicators that can provide therapeutic guidance and offer insights into eventual clinical outcomes. The success of surgical and rehabilitative interventions is often evaluated in terms of patient-reported outcome measures, return to activity, and pain. Although these factors are somewhat interdependent, each of them independently influences the final result. This article presents a comprehensive overview of the recent literature in this area to provide insight as to the short- and long-term outcomes that patients should expect based on their unique presentations. This article examines both intrinsic and extrinsic patient factors to help therapists develop customized rehabilitation programs that optimize surgical outcomes. PMID:23306420
