Abstract
Objective: Carcinosarcomas (malignant mixed mullerian tumor) of the female genital tract are rare tumors associated with poor outcome. Previous studies have demonstrated that even tumors of similar histology originating in organs that are in proximity may be biologically distinct entities by virtue of their occurrence through different molecular pathways. The objective of this study was to identify site specific differences in the clinical behavior and survival outcome of carcinosarcomas originating in female genital tract by comparing carcinosarcomas arising in the uterus and ovaries. Methods: Data on patients with uterine carcinosarcoma and ovarian carcinosarcoma were extracted from the Surveillance, Epidemiology, and End Results database between 1988 and 2005. Kaplan-Meier log rank and Cox proportional hazards models were used for survival analysis and to identify possible predictors for survival. Results: The identified cohort included 3,683 women, with 2,759 (75%) uterine carcinosarcomas and 924 (25%) ovarian carcinosarcomas. Uterine carcinosarcoma patients were older than patients with ovarian carcinosarcoma (median age 67.61 vs. 65.83 years, p<0.001). Women with uterine carcinosarcomas compared with ovarian carcinosarcoma were more often African American (17.3% versus 6%; P<0.001) and presented more often with early stage disease (Stage I/II 56.6% compared with 24.6%; P <0.001). Uterine compared to ovarian carcinosarcomas differed significantly with regards to the performance of salpingo-oopherectomy (96 % versus 99.4 %; P = 0.001), lymphadenectomy (62.6% versus 41.2%; P <0.001), and administration of radiotherapy (38.2% versus 4.8%; P <0.001). No difference was found in survival between patients with uterine and ovarian carcinosarcoma on stage- stratified Kaplan- Meier survival analysis or multivariate analysis using Cox model. Although, age (p<0.001), race (p<0.001), marital status (p<0.001), stage (p<0.001), lymphadenectomy (p<0.001), and radiation (p=0.005) were all significant prognostic factors in uterine carcinosarcoma, only age (p=0.001), stage (p<0.001), and lymphadenectomy(p<0.001) reached statistical significance in ovarian carcinosarcoma on multivariate analysis. Conclusion: Ovarian carcinosarcomas present at a more advanced stage and have a comparable prognosis at each stage with uterine carcinosarcomas. Improved survival observed in lymphadenectomy group argues in favor of routinely performing lymph node dissection in patients with uterine and ovarian carcinosarcoma.

Abstract
PURPOSE The goal of this study was to evaluate the outcomes and response in a cohort of patients with presumed platinum-sensitive disease who were subsequently retreated with platinum after receiving weekly bolus topotecan at the time of initial recurrence. METHODS A retrospective review of our institutional databases identified a cohort of platinum-sensitive women with recurrent ovarian and peritoneal carcinoma. Antitumor responses and toxicities were assessed for patients retreated with platinum-based chemotherapy following weekly bolus topotecan (4 mg/m²). RESULTS Twenty-six patients (median age 63 years, range 45-80 years) were identified. Advanced stage (III/IV) ovarian carcinoma was most common (96%). Residual disease after primary cytoreductive surgery was less than 1 cm in 65% of the cohort. Platinum retreatment was well tolerated. Grade 3 neutropenia occurred most commonly (8%) without any episodes of grade 4 myelotoxicity. Fatigue (12%) and hypersensitivity reaction (15%) were the most common non-hematologic toxicities during platinum retreatment. Of the 26 patients, 5 (19%) had a complete response, 5 (19%) had a partial response, 10 (39%) had stable disease, and 6 (23%) had progressive disease. Thirty-nine percent of patients with stable or progressive disease during weekly bolus topotecan responded to subsequent platinum retreatment. Response to platinum retreatment, treatment-free interval, and platinum-free interval was significant prognosticators for survival (P < 0.05). CONCLUSION(S) The results of this retrospective analysis suggest that weekly bolus topotecan, as intervening non-platinum, may result in acceptable toxicities and response rates during platinum retreatment in platinum-sensitive relapsed ovarian or peritoneal carcinoma.

Abstract
BACKGROUND Treatment of the multiligament-injured knee remains controversial. PURPOSE To compare clinical and functional outcomes of a consecutive series of multiligament-injured knees that underwent repair of the fibular collateral ligament (FCL) and posterolateral corner (PLC), followed by delayed cruciate ligament reconstructions, with those that had single-stage multiligament reconstruction. STUDY DESIGN Cohort study; Level of evidence, 3. Methods Patients with multiligament knee injury treated by a single surgeon were identified in our prospective database. Between February 2004 and May 2005, patients underwent repair of medial- and lateral-sided injuries, followed by delayed cruciate ligament reconstructions. Between May 2005 and February 2007, patients underwent single-stage multiligament knee reconstruction. All patients followed a standard rehabilitation protocol. Inclusion criteria were minimum 2-year follow-up and multiligament knee injury including the FCL/PLC. International Knee Documentation Committee subjective and Lysholm scores and objective clinical data were documented. RESULTS We identified 45 knees (42 patients); 17 knees (14 patients) were excluded, leaving 28 knees (28 patients) in the study. The repair/staged group (10 knees in 10 patients) had a mean follow-up of 34 months (range, 24-49 months). The reconstruction group (18 knees in 18 patients) had a mean follow-up of 28 months (range, 24-41 months). Four of the 10 FCL/PLC repairs (40%) and 1 of the 18 FCL/PLC reconstructions (6%) failed (P = .04). After revision reconstructions, there were no statistically significant differences between mean International Knee Documentation Committee subjective scores (79 vs. 77, P = .92) and mean Lysholm scores (85 vs 88, P = .92). Regression analysis showed no effect on failure based on age, sex, injury mechanism, time to surgery, interval between stages, total number of ligaments injured, or location of tear. CONCLUSION Our series demonstrated a statistically significant higher rate of failure for repair compared with reconstruction of the FCL/PLC. Reconstruction of the FCL/PLC structures is a more reliable option than repair alone in the setting of a multiligament knee injury.

Abstract
OBJECTIVE To apply ultrasound (US) imaging techniques to better describe the characteristics of myofascial trigger points (MTrPs) and the immediately adjacent soft tissue. DESIGN Four sites in each patient were labeled based on physical examination as active myofascial trigger points (A-MTrPs; spontaneously painful), latent myofascial trigger points (L-MTrPs; nonpainful), or normal myofascial tissue. US examination was performed on each subject by a team blinded to the physical findings. A 12 approximately 5MHz US transducer was used. Vibration sonoelastography (VSE) was performed by color Doppler variance imaging while simultaneously inducing vibrations (approximately 92Hz) with a handheld massage vibrator. Each site was assigned a tissue imaging score as follows: 0, uniform echogenicity and stiffness; 1, focal hypoechoic region with stiff nodule; 2, multiple hypoechoic regions with stiff nodules. Blood flow in the neighborhood of MTrPs was assessed using Doppler imaging. Each site was assigned a blood flow waveform score as follows: 0, normal arterial flow in muscle; 1, elevated diastolic flow; 2, high-resistance flow waveform with retrograde diastolic flow. SETTING Biomedical research center. PARTICIPANTS Subjects (N=9) meeting Travell and Simons' criteria for MTrPs in a taut band in the upper trapezius. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES MTrPs were evaluated by (1) physical examination, (2) pressure algometry, and (3) three types of US imaging including gray-scale (2-dimensional [2D] US), VSE, and Doppler. RESULTS MTrPs appeared as focal, hypoechoic regions on 2D US, indicating local changes in tissue echogenicity, and as focal regions of reduced vibration amplitude on VSE, indicating a localized, stiff nodule. MTrPs were elliptical, with a size of .16+/-.11 cm(2). There were no significant differences in size between A-MTrPs and L-MTrPs. Sites containing MTrPs were more likely to have a higher tissue imaging score compared with normal myofascial tissue (P<.002). Small arteries (or enlarged arterioles) near A-MTrPs showed retrograde flow in diastole, indicating a highly resistive vascular bed. A-MTrP sites were more likely to have a higher blood flow score compared with L-MTrPs (P<.021). CONCLUSIONS Preliminary findings show that, under the conditions of this investigation, US imaging techniques can be used to distinguish myofascial tissue containing MTrPs from normal myofascial tissue (lacking trigger points). US enables visualization and some characterization of MTrPs and adjacent soft tissue.

Abstract
BACKGROUND Golf provides an opportunity for relatively low-impact exercise for nearly all age groups and is considered a recommended activity for patients after total knee arthroplasty. HYPOTHESIS We hypothesized that total knee arthroplasty would afford patients increased ability to participate in and enjoy golf, allowing a large percentage of these patients to walk the golf course. STUDY DESIGN Case series; Level of evidence, 4. METHODS Surveys were sent to 151 golfers who had undergone primary total knee arthroplasty from 1995 to 2000. The detailed survey included 33 questions specific to the patients' golf performance, enjoyment of golf, frequency of participation, timing of return to play, presence of pain, use of a cart, and related golf-specific issues. RESULTS We received and evaluated 93 responses (62%). Fifty-seven percent reported they had returned to golf within 6 months after total knee arthroplasty. Eighty-one percent of respondents reported golfing as frequently, or more frequently, than before knee replacement. Notably, golfers reported less pain while golfing after total knee arthroplasty than before (13% vs 83%; P < .0001), and 94% of respondents reported currently enjoying golf as much as or more than before surgery. Twenty-eight percent of respondents stated that they walked the course, rather than using a motorized golf cart, before surgery, while only 14% walked the course after surgery (P = .02). CONCLUSION In this population of golfers, total knee arthroplasty reliably relieved pain that had been previously experienced while golfing, and increased or maintained this group's enjoyment of playing golf. However, 86% of these patients reported using a cart while golfing. Further patient education is needed regarding the potential health benefits of walking during golf after total knee arthroplasty.

Abstract
While it is generally accepted that most partial and isolated medial collateral ligament (MCL) injuries can be treated non-operatively, ideal treatment of the MCL in multi-ligament knee injuries remains controversial. High failure rates with repair of the posterolateral corner in the multi-ligament injured knee have been recently reported, favoring reconstruction instead. The same maybe true for MCL injuries, however evidence-based treatment recommendations are lacking in the current orthopedic literature. The purpose of this study was to perform an evidence-based systematic review of the operative management (repair and/or reconstruction) of the MCL in the setting of multi-ligament knee injuries. A comprehensive search of MEDLINE and the Cochrane databases for all relevant articles published in English from 1978 to 2008 on the outcomes of surgical management (repair and/or reconstruction) of the MCL in the setting of combined ligament injuries was performed. Inclusion criteria included articles published in (1) English, (2) on human subjects, (3) between the years of 1978 and 2008, (4) had minimum 12-month follow-up, with a mean of at least 24 months, (5) on surgical management of MCL injuries, (6) associated with multi-ligament injuries (three or more ligaments) and/or knee dislocation, and (7) reported objective outcome data on the respective patient cohorts. Exclusion criteria consisted of technique papers, case reports, studies that included fractures associated with MCL injury and those that included pediatric patients. The review identified eight relevant studies. Five articles focused on MCL repair, while three articles focused on MCL reconstruction. No prospective studies compared MCL repair or reconstruction with non-operative treatment or directly compared MCL reconstruction with MCL repair. Currently there is a paucity of objective data on the outcomes regarding surgical management of MCL tears in the combined ligament injured knee. This systematic review demonstrated satisfactory results in both repair and reconstruction groups. Future objective outcome-based studies as well as comparative studies are needed to further evaluate the optimal treatment modality before evidence-based recommendations can be made. Therefore, individual treatment decisions for each patient should be based on the characteristics and nature of the injury.

Abstract
OBJECTIVE(S) To compare the survival of African American (AA) and white (W) patients with malignant germ cell tumors of the ovary (OGCT). METHODS Patients with a diagnosis of OGCT were identified from Surveillance, Epidemiology, and End Results Program (SEER) from 1988 to 2004, and were divided into African American (AA) and white (W) subgroups. Only surgically treated patients were included. Histology was grouped into dysgerminoma (D), malignant teratoma (MT), and mixed germ cell tumors with pure non-dysgerminoma cell tumors (MGCT/PNDCT). Statistical analysis using Chi-square, Fisher's Exact Test, Kaplan-Meier survival methods, and Cox regression proportional hazards were performed. RESULTS In 1110 patients with OGCT, 970 (87.4%) were W and 140 (12.6%) were AA. MGCT/PNDCT histology was equally represented in AA and W. However, W were twice as likely to present with D (W 34% vs. AA 16%, p<0.01) and 1.5 times less likely to present with MT (W 41% vs. AA 59%, p<0.01). The majority (W 64%, AA 64%) of OGCT were stage I. Advanced stage (FIGO III and IV) tumors were more prominent in AA (24% vs. 18%, p>0.05). Complete surgical staging effort was utilized more frequently in W (49%) as compared to AA (38%; p=0.001). Overall 5-year survival was 92% for W and 86% for AA (p=0.02). In multivariate analysis race was not an independent predictor of survival when histology, stage and surgical staging were controlled. CONCLUSION(S) In our study, a higher prevalence of complete surgical staging and a favorable distribution of low risk histologic types may explain the improved survival observed in white patients with OGCT. However, race was not an independent predictor of survival.

Abstract
Myofascial trigger points (MTrPs) are palpable hyperirritable nodules in skeletal muscle that are associated with chronic musculoskeletal pain. The goal of this study was to image MTrPs in the upper trapezius muscle using 2D gray scale ultrasound (US) and vibration sonoelastography (VSE) for differentiating the soft tissue characteristics of MTrPs compared to surrounding muscle. MTrPs appeared as hypoechoeic elliptically-shaped focal regions within the trapezius muscle on 2D US. Audio-frequency vibrations (100-250 Hz) were induced in the trapezius muscle of four volunteers with clinically identifiable MTrPs, and the induced vibration amplitudes were imaged using the color Doppler variance mode, and were further quantified using spectral Doppler analysis. Spectral Doppler analysis showed that vibration amplitudes were 27% lower on average within the MTrP compared to surrounding tissue (p0.05). Color variance imaging consistently detected a focal region of reduced vibration amplitude, which correlated with the hypoechoeic region identified as an MTrP (r =0.76 for area). Real-time 2D US identifies MTrPs, and VSE is feasible for differentiating MTrPs from surrounding tissue. Preliminary findings show that MTrPs are hypoechoeic on 2D US and the relative stiffness of MTrPs can be quantified using VSE. Ultrasound offers a convenient, accessible and low-risk approach for identifying MTrPs and for evaluating clinical observations of palpable, painful nodules.

Abstract
OBJECTIVE The purpose of this study was to compare the prognostic variables and survival of younger (< 50 years) to that of older (> or = 50 years) women with vulvar cancer. STUDY DESIGN Subjects with invasive squamous cell carcinoma of the vulva were identified from the limited use Surveillance, Epidemiology, and End Results (SEER) Program 1988-2005. Comparisons between younger and older women were accomplished with chi(2) and t-tests. Survival analysis was accomplished with Kaplan-Meier for univariate analysis and Cox proportional hazards model for multivariate analysis. RESULTS A total of 6965 patients met inclusion criteria, of whom 1345 patients (19.3%) were younger and 5620 patients (80.7%) were older. The 5-year survival was 87.5% for younger women and 52.5% for older women (P < .001). After data were controlled for race, stage, grade, and surgical treatment, older patients had a hazard ratio of 3.9 (95% CI, 3.2-4.7) for death. CONCLUSION A striking survival difference exists between younger and older women with squamous cell vulvar cancer, which supports the view that etiopathogenesis of this disease may vary between age groups.

Abstract
BACKGROUND Psammocarcinoma is a rare form of low grade serous carcinoma of the ovary or peritoneum. Although limited to case reports and small series, psammocarcinoma appears to have an indolent course. CASE A 27-year-old, nulliparous female presented with an adnexal mass. Following fertility-sparing surgery and adjuvant chemotherapy, she was able to achieve a successful pregnancy. Fifteen years after initial conservative treatment, she remains without pathologic evidence of cancer. CONCLUSION Psammocarcinoma are rare neoplasms that appear to have an indolent clinical course. Pregnancy after the diagnosis and treatment of psammocarcinoma may not alter the clinical course of the disease.

Abstract
PURPOSE The purpose of this study was to investigate the functional and clinical outcomes of a consecutive series of patients who underwent fibular collateral ligament (FCL) and posterolateral corner (PLC) reconstruction by use of a single Achilles tendon allograft construct. METHODS Patients were identified through prospective sports medicine databases at 2 academic institutions. Only patients who had undergone FCL and PLC reconstruction (as opposed to repair) were included. All patients followed a standard postoperative rehabilitation protocol. Various patterns of combined ligament injuries were included and divided into 2 groups (2 ligament v multiligament). Functional and clinical outcomes were assessed by clinical examination, Lysholm scores, and International Knee Documentation Committee subjective scores. Statistical analysis was performed by use of Wilcoxon paired rank-sum tests and multivariate regression. RESULTS We identified 16 knees in 16 patients, with a minimum of 2 years' follow-up. There were 13 men and 3 women. The mean age was 30 years (range, 19 to 61 years). The mean length of clinical follow-up was 30 months (range, 24 to 75 months). The mean International Knee Documentation Committee subjective scores were 80 points and 80 points (P = .79) in the 2-ligament and multiligament groups, respectively, and the mean Lysholm scores were 90 points and 89 points (P = .96), respectively. Age (P = .41), gender (P = .84), and interval between injury and surgery (P = .72) did not affect the clinical and functional outcomes between the 2 groups. Arthrofibrosis requiring manipulation developed in 1 patient. Residual varus laxity (1+) was noted in 4 patients, none of whom displayed functional instability. No patient has required revision reconstruction to date. CONCLUSIONS We describe a novel technique that takes into account the main static PLC stabilizers (FCL, popliteofibular ligament, and posterolateral capsule) that has not been previously reported. Our series showed no significant differences in clinical and functional outcomes between 2-ligament and multiligament PLC-based reconstructions. However, given the heterogeneity and small sample size of our study group, it is difficult to draw qualitative conclusions. LEVEL OF EVIDENCE Level IV, therapeutic case series.

Abstract
Anatomic variations in the insertion of the long head of the biceps tendon and superior labral complex have been described (Erickson et al. [1992] AJR Am. J. Roentgenol. 158:1091-1096; Kreitner et al. [1998] AJR Am. J. Roentgenol. 170:599-605; Mariani et al. [1997] Arthroscopy 13:499-501; Vangsness Jr. et al. [1994] J. Bone Joint Surg. Br. 76:951-954). To the authors' knowledge, there have been only five reported cases of congenital absence of the long head of the biceps tendon. Three of these cases were associated with anterior shoulder instability, one with a superior labral anterior posterior lesion and one simply with shoulder pain. This is the first reported case of congenital absence of the biceps tendon associated with glenoid dysplasia and a posterior labral tear.

Abstract
Yolk sac tumors (YST) are a rare and aggressive germ cell tumor. The objective of this study is to compare the patient characteristics and survival of YST in males and females. Demographic and clinicopathologic information were obtained from the Surveillance, Epidemiology, and End Results Program from 1973 to 2003. Statistical analysis was performed using Independent-sample t-test, chi(2) test, Kaplan-Meier methods and Cox proportional hazards regression. Seven hundred eighty-eight patients were identified, 451 (57%) were males and 337 (43%) were females. The mean age at diagnosis was similar in males and females. The age at diagnosis showed a bimodal distribution with an increased incidence in the first 4 years of life and during the 2nd to 4th decade of life. The most common site of the primary tumor was gonadal, namely testis 336 (42.6%) and ovary 257 (32.6%). Among the extragonadal sites, tumor site of origin differed in males and females. The 5-year survival of extragonadal YST (66%) was worse than gonadal YST (86%) (p < 0.05). The overall median survival for the cohort was 87 months. This was similar in males (81 months) and females (91 months) (p > 0.05). As the year of diagnosis progressed from 1973 to 2003, survival of both males and females with YST consistently improved. The bimodal age distribution of YST generates the hypothesis that sex steroids may play a role in selected YST. Although the overall survival in all YST patients has improved over the past few decades, the primary sites of origin differ in males and females and impact prognosis.

Abstract
BACKGROUND The purpose of this study is to report the prevalence and prognostic importance of lymph node metastasis in malignant germ cell tumors of the ovary (OGCT). METHODS Demographic and clinicopathologic information were abstracted from the Surveillance, Epidemiology, and End Results Program (SEER) from 1988 to 2004. Patients with a histologic diagnosis of OGCT after surgical resection were included. The study population was divided into Cohort A (lymph node metastasis absent) and Cohort B (lymph node metastasis present). Statistical analysis using Fisher's Exact Test, Kaplan-Meier survival methods, and Cox regression proportional hazards were performed. RESULTS In 613 patients with lymphadenectomy, the prevalence of lymphnode metastasis was 18.1% (111/613). In dysgerminoma, malignant teratoma and mixed germ cell tumors including pure non-dysgerminoma histology, the lymphnode metastasis was present in 28%, 8% and 16% patients respectively (p<0.05). Age, race, grade and extent of lymph node dissection influenced lymph node involvement but this was statistically not significant. Five year survival in Cohort A was 95.7% compared to 82.8% in Cohort B (p<0.001). After controlling for age, race, stage, grade and histology, multivariate analysis revealed the presence of lymph node involvement as an independent predictor of poor survival with a hazards ratio of 2.87 (95% CI 1.439-5.725; p<0.05). CONCLUSIONS Prevalence of lymph node metastasis varies according to histology in OGCT and is an independent predictor of poor survival in these patients. These findings highlight the value of lymphadenectomy and may be helpful in creating risk stratification models for individualization of adjuvant therapies.

Abstract
BACKGROUND Acute hypoxemic respiratory failure (AHRF) is an important cause of mortality and morbidity in children. Positive pressure ventilation is currently the standard care, however, it does have complications. Continuous negative extrathoracic pressure ventilation (CNEP) or continuous positive airway pressure (CPAP) ventilation delivered via non-invasive approaches (Ni-CPAP) have shown certain beneficial effects in animal and uncontrolled human studies. OBJECTIVES The primary objective was to assess the effectiveness of CNEP or Ni-CPAP in pediatric patients with AHRF from non-cardiogenic causes. SEARCH STRATEGY We searched the Cochrane Central Register of Controlled Trials (The Cochrane Library 2007, Issue 3); MEDLINE (January 1966 to July 2007); EMBASE (1980 to July 2007); CINAHL (1982 to July 2007); and published abstracts from the meetings of the American Thoracic Society and Pediatric Critical Care Meetings (1992 to 2007). SELECTION CRITERIA Randomized or quasi-randomized clinical trials of either CNEP or Ni-CPAP versus standard therapy (including positive pressure ventilation) involving children (at least 1 month old and less than 18 years of age at the time of randomization) who met the criteria for diagnosis of AHRF with at least one of the outcomes reported were included. DATA COLLECTION AND ANALYSIS Risks of bias of the included study was assessed using: concealment of allocation, blinding of intervention, completeness of follow up and blinding of outcome measurements. Data on relevant outcomes were abstracted and the effect size was estimated by calculating relative risk (RR) with 95% confidence intervals (CI) and risk difference (RD). MAIN RESULTS One eligible study published in an abstract format was identified. It studied 33 infants (18 controls, 15 receiving CNEP) with a clinical diagnosis of bronchiolitis and fraction of inspired oxygen (FiO(2)) > 40% were studied. This allowed a reduction in the FiO(2) (< 30% within one hour of initiation of therapy) in four patients in the CNEP group compared to none in the control group (RR 10.7, 95% CI 0.6 to 183.9). One infant required CPAP and one infant required nasal CPAP in the control group while all infants in the CNEP group were managed without intubation (RR for both outcomes 0.40, 95% CI 0.02 to 9.06). AUTHORS' CONCLUSIONS There is a lack of well designed, controlled experiments of non-invasive modes of respiratory support in children with AHRF. Reduction of in-hospital mortality is an important outcome and even a small reduction would be beneficial. Studies assessing other outcomes such as avoidance of intubation and its associated complications, reduction in hospital stay and improvement in patient comfort are also valuable in gauging the overall impact of these strategies.
