ObjectiveLaparoscopic uterine artery ligation may be performed during myomectomy or other uterine invasive procedures to reduce the amount of blood loss during surgery. In this video, the authors describe 3 different laparoscopic techniques to approach the uterine artery.DesignStep-by-step video demonstration of 3 different surgical techniques.SettingPrivate hospital in Curitiba, Paraná, Brazil.InterventionsThe main steps of uterine artery ligation are described in detail as well as different laparoscopic variants to this procedure.Anterior ApproachThe impression of the uterine vessels can usually be seen anteriorly and laterally to the uterine cervix. After identification of the path of the uterine arteries, the peritoneum of the anterior cul-de-sac is opened over the vessels and the uterine artery is carefully dissected next to the lateral border of the uterine cervix. This dissection must be performed with extreme caution because the uterine veins are very close to the artery. Venous bleeding at this point of the dissection can be very difficult to control without ligating the vessels. After circumferential dissection of the artery, temporary occlusion is conducted using 2-0 polyester suture.Posterior Approach, Lateral to the Infundibulopelvic LigamentFor ligation of the uterine artery posteriorly to the uterus and laterally to the pelvic infundibulum, opening of the peritoneum of the broad ligament should start immediately below the round ligament, parallel and medial to the external iliac vessels toward the base of the pelvic infundibulum. The avascular space is dissected by blunt dissection (traction and countertraction), identifying the lateral (external iliac vessels) and medial (pelvic infundibulum and the ureter attached to the peritoneum of the ovarian fossa) landmarks. The external iliac artery is dissected cranially to find the bifurcation of the common iliac artery and the internal iliac artery. The first medial branch of the anterior division of the internal iliac usually is the uterine artery. After circumferential dissection of the uterine artery, it may be ligated according to the same technique described above.Medial ApproachFor the medial approach, the peritoneum should be opened medial to the infundibulopelvic ligament. The assistant grasps the infundibulopelvic ligament, creating a peritoneal tent. Immediately after broad ligament opening, anatomic landmarks are identified. First, the ureter is identified and medialized. For the identification of vascular anatomy, movement of the obliterated umbilical artery is made active, which reduces the risk of error to ligate the uterine artery. After circumferential dissection of the artery, it may be ligated according to the same technique described above.ConclusionLaparoscopic uterine artery ligation may be performed during laparoscopic myomectomy to reduce intraoperative blood loss. According to the position of the myomas within the uterus as well as the uterine volume, the surgeon may choose among 1 of the above-mentioned techniques to perform. This technique could also be applied to other types of invasive uterine procedures to reduce blood loss. Standardization of these techniques could help to reduce the laparoscopic learning curve. 相似文献

Study ObjectiveTo evaluate the clinical parameters of hospitalized patients with pelvic inflammatory disease (PID) for the presence of tubo-ovarian abscess (TOA) and predict the need for intervention.DesignA prospective cohort study.SettingA tertiary care university medical center.PatientsNinety-four patients were diagnosed with complicated PID and hospitalized between 2015 and 2017.InterventionsPatients with PID were treated with parenteral antibiotics according to Centers for Disease Control guidelines. Demographic, clinical, sonographic, and laboratory data for patients with PID were analyzed. Inflammatory markers including C-reactive protein (CRP), white blood cells (WBCs), erythrocyte sedimentation rate (ESR), and clinical parameters were collected at admission and during hospitalization.Measurements and Main ResultsForty-eight of 94 patients (51.1%) hospitalized with complicated PID were diagnosed with TOA sonographically. CRP levels were the strongest predictor of TOA, followed by WBC count, ESR, and fever on admission. The areas under the receiver operating characteristic (ROC) curve for CRP, WBC, ESR, and fever were .92, .75, .73 and .62, respectively. CRP specificity was 93.4% and sensitivity was 85.4% for predicting TOA, with cutoff value of 49.3 mg/L. Twelve patients (25%) failed conservative management and underwent surgical intervention including laparoscopy (n = 7), computed tomography (CT)-guided drainage (n = 4), and laparotomy (n = 1). In this group, CRP levels significantly increased from admission to day 1 and day 2 during hospitalization (128.26, 173.75, and 214.66 mg/L, respectively; p < .05 for both). In the conservative management group, CRP levels showed a plateau from admission to day 1 and then a decrease until day 3 (110, 120.49, 97.52, and 78.45 mg/L, respectively).ConclusionCRP is a sensitive, specific inflammatory marker for predicting TOA in patients with complicated PID, and levels >49.3 mg/L suggest the presence of TOA. In the TOA group, CRP level trends correlated well with success or failure of conservative management. Increasing CRP levels during treatment may be used as an indicator of the need for invasive intervention, and daily CRP measurements can help predict the need for invasive intervention. 相似文献

Elizabethkingia anophelis, recently discovered from mosquito gut, is an emerging bacterium associated with neonatal meningitis and nosocomial outbreaks. However, its transmission route remains unknown. We use rapid genome sequencing to investigate 3 cases of E. anophelis sepsis involving 2 neonates who had meningitis and 1 neonate’s mother who had chorioamnionitis. Comparative genomics revealed evidence for perinatal vertical transmission from a mother to her neonate; the 2 isolates from these patients, HKU37 and HKU38, shared essentially identical genome sequences. In contrast, the strain from another neonate (HKU36) was genetically divergent, showing only 78.6% genome sequence identity to HKU37 and HKU38, thus excluding a clonal outbreak. Comparison to genomes from mosquito strains revealed potential metabolic adaptations in E. anophelis under different environments. Maternal infection, not mosquitoes, is most likely the source of neonatal E. anophelis infections. Our findings highlight the power of genome sequencing in gaining rapid insights on transmission and pathogenesis of emerging pathogens. 相似文献

In 2011, a large community outbreak of human adenovirus (HAdV) in Taiwan was detected by a nationwide surveillance system. The epidemic lasted from week 11 through week 41 of 2011 (March 14–October 16, 2011). Although HAdV-3 was the predominant strain detected (74%), an abrupt increase in the percentage of infections caused by HAdV-7 occurred, from 0.3% in 2008–2010 to 10% in 2011. Clinical information was collected for 202 inpatients infected with HAdV; 31 (15.2%) had severe infection that required intensive care, and 7 of those patients died. HAdV-7 accounted for 10%, 12%, and 41% of infections among outpatients, inpatients with nonsevere infection, and inpatients with severe infection, respectively (p<0.01). The HAdV-7 strain detected in this outbreak is identical to a strain recently reported in the People’s Republic of China (HAdV7-HZ/SHX/CHN/2009). Absence of circulating HAdV-7 in previous years and introduction of an emerging strain are 2 factors that caused this outbreak. 相似文献

Levofloxacin resistance in Haemophilus influenzae has increased significantly in Taiwan, from 2.0% in 2004 to 24.3% in 2010 (p<0.001). Clinical and molecular investigations of 182 levofloxacin-resistant isolates revealed that the increase was mainly the result of the spread of several clones in the elderly population in different regions. 相似文献

We developed an assay that detects minus-strand RNA as a surrogate for actively replicating severe acute respiratory syndrome coronavirus 2. We detected minus-strand RNA in 41 persons with coronavirus disease up to 30 days after symptom onset. This assay might inform clinical decision-making about patient infectiousness. 相似文献

ObjectiveWeight bias can influence medical care but has not been studied in the pediatric inpatient setting. We will quantify implicit and explicit weight bias of pediatric inpatient providers and qualitatively explore providers’ attitudes toward children with obesity and patient/family perceptions of weight bias in the hospital.MethodsWe performed a mixed-methods study including semistructured key informant interviews and validated tests for implicit (Implicit Association Test) and explicit (Crandall's Anti-Fat Attitudes Questionnaire) bias with pediatric hospitalists, residents, and acute care nurses. We performed semistructured key informant interviews with pediatric inpatients aged 7 to 17 years and the patient's parent(s) or guardian(s). Interviews were coded using an inductive approach to identify recurrent themes.ResultsWe enrolled 28 pediatric providers, 12 patients, and 12 parents/guardians. In total, 71% of providers exhibited moderate or strong implicit weight bias, with generally lower scores for explicit bias. Qualitative analysis identified seven themes: the existence of weight bias, shared responsibility for a child's obesity, a potential for provider bias toward the parents of pediatric patients with obesity, possible effects of patient weight on inpatient care, importance of terminology in addressing obesity, and the possibility of addressing obesity inpatient but a preference for obesity to be addressed in the outpatient setting.ConclusionsHealth care providers, patients, and families in the pediatric inpatient setting identified multiple ways that obesity could impact care, including provider weight bias. 相似文献

Human penicilliosis marneffei is an emerging infectious disease caused by the fungus Penicillium marneffei. High prevalence of infection among bamboo rats of the genera Rhizomys and Cannomys suggest that these rodents are a key facet of the P. marneffei life cycle. We trapped bamboo rats during June 2004-July 2005 across Guangxi Province, China, and demonstrated 100% prevalence of infection. Multilocus genotypes show that P. marneffei isolates from humans are similar to those infecting rats and are in some cases identical. Comparison of our dataset with genotypes recovered from sites across Southeast Asia shows that the overriding component of genetic structure in P. marneffei is spatial, with humans containing a greater diversity of genotypes than rodents. Humans and bamboo rats are sampling an as-yet undiscovered common reservoir of infection, or bamboo rats are a vector for human infections by acting as amplifiers of infectious dispersal stages. 相似文献
