Does the Difference in Fascial Closure Technique Affect Postoperative Pain?

STUDY OBJECTIVE: To compare postoperative incisional pain on postoperative days (PODs) 1 and 14 when using a fascial closure device (FCD) versus a traditional fascial closure (TFC) of the 12-mm upper quadrant port during robotic surgery. Time required to close the incision was also compared. DESIGN: Randomized controlled trial (Canadian Task Force classification I). SETTING: Two academic affiliated hospitals, The Hospital of Central Connecticut and The University of Connecticut. PATIENTS: Women undergoing robotic surgery for benign indications by minimally invasive gynecologists at our institutions between November 2012 and October 2014 were enrolled in the study at their preoperative visit. INTERVENTIONS: Patients were randomized to either an FCD or TFC immediately before closure of the fascial incision. Pain score using a 10-point analog pain scale was recorded on POD 1 and POD 14. Time to close the fascial incision, length of surgery, and body mass index were also recorded. MEASUREMENTS AND MAIN RESULTS: Sixty-seven patients were enrolled, and 65 were randomized at the time of the fascial closure, whereas 2 enrolled patients converted to laparotomy. Statistical analysis demonstrated that pain scores differed by fascial closure technique. Mean pain scores on POD 1 were 3.43 ± 2.48 and 2.06 ± 2.03 for the FCD and TFC, respectively (p = .028). On POD 14 the mean pain scores were 1.97 ± 2.48 and .83 ± 1.42 for the FCD and TFC, respectively (p = .102). Times to close fascia were 106.5 ± 102.28 seconds and 141.97 ± 102.85 seconds for the FCD and TFC, respectively (p = .138). CONCLUSION: Our study demonstrates that at POD 1 the use of the fascia closure device results in higher pain scores without a significant difference in closure time.

Incidence of Septate Uterus in Reproductive-Aged Women With and Without Endometriosis.

STUDY OBJECTIVE: To compare the incidence of a uterine septum in women with and without endometriosis and if such incidence correlates with the stage of endometriosis Although a correlation between obstructive Mullerian anomalies and endometriosis has been well established, its link with non-obstructive anomalies remains controversial. To elucidate whether there is a correlation between endometriosis and non-obstructive Mullerian anomalies, we conducted this prospective study on all patients admitted to our Reproductive Endocrinology and Infertility surgical service from February 1, 2010 through June 30, 2012. All patients underwent both hysteroscopy and laparoscopy. Surgical indications included: infertility, pain, and/or menorrhagia. The presence or absence of endometriosis and uterine anomalies were recorded immediately after each surgery and subsequently analyzed. Endometriosis was staged according to the r-ASRM Classification and treated by resection and ablation of deep and superficial lesions, respectively. Since uterine septum is the most common Mullerian anomaly, we considered only this anomaly to test the hypothesis that uterine septum may be associated with an increased incidence of endometriosis. DESIGN: Prospective Study. Evidence from a well-designed case-control study (Canadian Task Force classification II-2). SETTING: University-affiliated tertiary care center. PATIENTS: Reproductive aged women admitted to our service for treatment of pelvic pain, abnormal uterine bleeding, and/or infertility. INTERVENTION: All patients underwent both hysteroscopy and laparoscopy as part of their evaluation and treatment of pelvic pain, abnormal uterine bleeding, and/or infertility. MEASUREMENTS AND MAIN RESULTS: 343 patients were included in the study. The diagnosis of each patient included infertility - 52, pain - 215, both - 30 and other - 46. The diagnosis of septate uterus was made at hysteroscopy when the endometrial cavity was separated by an avascular septum that obscured visualization of both cornua when the hysteroscope was advanced to the mid-uterine segment. The septum was lysed sharply from cornua to cornua restoring normal fundal configuration. In all cases, the septolysis was bloodless, confirming its avascular nature. The overall incidence of uterine septum was 33% in our patient population. In patients with a histologically confirmed diagnosis of endometriosis, the incidence of septum was 37% versus 27% in patients without endometriosis (P = .046). In patients with advanced endometriosis, Stage IV disease, the incidence of septate uterus was 41% (P = .022). The odds ratio of Stage IV endometriosis with a uterine septum was 1.94 (CI 1.09-3.44). CONCLUSION: The incidence of septate uterus in our population of women with infertility and/or pelvic pain ranges from 27% to 37%, being significantly higher in women with endometriosis and mores so with Stage IV disease. Our data suggests that the presence of a uterine septum may predispose to more advanced disease.

Three-dimensional ultrasound in diagnosis of adenomyosis: histologic correlation with ultrasound targeted biopsies of the uterus.

STUDY OBJECTIVE: To evaluate the accuracy of 3-dimensional transvaginal sonography (3D TVS) in the diagnosis of adenomyosis by correlating adenomyosis-induced morphologic alterations in the myometrium and the junctional zone (JZ) with histopathologic features of targeted biopsy specimens of the uterus. DESIGN: Prospective study (Canadian Task force classification II-2). SETTING: Private practice associated with a university program. PATIENTS: Symptomatic premenopausal women scheduled to undergo hysterectomy because of benign conditions. INTERVENTIONS: Patients underwent preoperative 3D TVS of the uterus to evaluate alterations to the JZ, to measure the smallest (JZ(min)) and largest (JZ(max)) JZ thickness, and to assess for the presence of myometrial heterogeneous and cystic areas, hyperechoic striations, and asymmetry of the myometrial wall. Localization and position of the lesions in the myometrial wall were accurately recorded. Results of the sonographic features were correlated with the histopathologic findings of the ultrasound-based targeted biopsy specimens of the uterus. MEASUREMENTS AND MAIN RESULTS: The study included 54 symptomatic premenopausal women with a mean age of 42.1 years. Of these, 12 had previously undergone endometrial ablation and 10 were receiving medical therapy, and these patients were considered separately for the statistical analysis. The prevalence of adenomyosis at histology was 66.6% (36/54). Of 32 patients who had received no previous treatment, 26 had adenomyosis on the targeted biopsy specimens of the myometrium. 3D TVS features of adenomyosis with the best specificity (83%) and positive predictive values were JZ(max) ≥8 mm, myometrial asymmetry, and hypoechoic striation. When we considered the presence of at least 2 of the described ultrasound features for the diagnosis of adenomyosis, accuracy was 90% (sensitivity, 92%; specificity, 83%; positive predictive value, 99%; and negative predictive value, 71%). Diagnostic accuracy was decreased to 50% in patients who had previously undergone endometrial ablation, and to 60% in patients receiving medical therapy. CONCLUSION: 3D TVS demonstrates high diagnostic accuracy in detection of site and position of adenomyosis in the uterine walls. Endometrial ablation and medical therapy alter the appearance of the JZ, compromising the accuracy of 3D US in enabling the diagnosis of adenomyosis.

Hantavirus pulmonary syndrome-associated hantaviruses contain conserved and functional ITAM signaling elements.

Hantaviruses infect human endothelial and immune cells, causing two human diseases, hemorrhagic fever with renal syndrome (HFRS) and hantavirus pulmonary syndrome (HPS). We have identified key signaling elements termed immunoreceptor tyrosine-based activation motifs (ITAMs) within the G1 cytoplasmic tail of all HPS-causing hantaviruses. ITAMs direct receptor signaling within immune and endothelial cells and the presence of ITAMs in all HPS-causing hantaviruses provides a means for altering normal cellular responses which maintain vascular integrity. The NY-1 G1 ITAM was shown to coprecipitate a complex of phosphoproteins from cells, and the G1 ITAM is a substrate for the Src family kinase Fyn. The hantavirus ITAM coprecipitated Lyn, Syk, and ZAP-70 kinases from T or B cells, while mutagenesis of the ITAM abolished these interactions. In addition, G1 ITAM tyrosines directed intracellular interactions with Syk by mammalian two-hybrid analysis. These findings demonstrate that G1 ITAMs bind key cellular kinases that regulate immune and endothelial cell functions. There is currently no means for establishing the role of the G1 ITAM in hantavirus pathogenesis. However, the conservation of G1 ITAMs in all HPS-causing hantaviruses and the role of these signaling elements in immune and endothelial cells suggest that functional G1 ITAMs are likely to dysregulate normal immune and endothelial cell responses and contribute to hantavirus pathogenesis.
