Clermont-Ferrand versus Vectec uterine manipulator for total laparoscopic hysterectomy

Objective: To compare the operation time and performance of two uterine manipulators used for total laparoscopic hysterectomy (TLH).

Material and methods: Design: Retrospective cohort analysis. Design classification: Canadian Task Force Classification II-2. Setting: Tertiary-care university-based teaching hospital and academic affiliated private hospital. Patients: All consecutive patients who underwent for TLH between January 2014 and June 2017. All operations were performed by two expert endoscopic surgeons using one of the following uterine manipulators depending on surgeon preferences: Clermont-Ferrand (CF) or Vectec (VT) MAUT60. Patients were excluded if additional surgeries such as urogynecological procedures were performed, TLH was converted to laparotomy prior to colpotomy, and when their operation records could not be obtained. A total of 169 patients were added to final analysis. Operation time, colpotomy time and the subjective performance of manipulators such as movement of the uterus, visualization of the vaginal fornices, and maintenance of pneumoperitoneum were evaluated by watching un-edited operation videos.

Results: A total of 169 patients (83 patients in CF group; 86 patients in VT group) were included in the final analysis. Patients’ baseline characteristics were comparable between groups. Operation time and time required for colpotomy were significantly shorter in the VT group. Lateral movements of the manipulators and elevation of the uterus were better with VT compared to CF (p?=?.001 for both). Compared to the CF, VT was superior for visualization of the vaginal fornices (p?=?.004) and maintenance of pneumoperitoneum (p?<?.001). Both surgeons had perfect agreement on the performance grading of manipulators (p?<?.001, Kappa values were between 0.86–0.92). There was no difference between groups in estimated blood loss and duration of hospital stay. Reinsertion or the need to change the manipulator was not required in either group. No pelvic or vaginal abscess, cuff cellulitis, dehiscence, or hematoma formations were noted.

Conclusion: Laparoscopic hysterectomy assisted with the VT uterine manipulator is associated with shorter operation and colpotomy time. Furthermore, the movements of uterus, visualization of the vaginal fornices, and maintenance of pneumoperitoneum were significantly better with VT compared to the CF manipulator.     

Symptômes négatifs de la schizophrénie : une revue des instruments d’évaluation

IntroductionNegative symptoms are a fundamental dimension of schizophrenia despite their limited role in the international diagnostic classification. Although a consensual definition seems to be attempted regarding the main negative dimensions (anhedonia, alogia, social withdrawal, blunted affect, avolition), several standardized assessment scales have been created.ObjectivesThe objective of this study was to identify a set of unidimensional instruments which allows an assessment of negative symptoms in schizophrenia and also to identify their general characteristics and the items included.MethodsInclusion criteria were: (a) the unidimensional assessment scales of negative symptoms of schizophrenia; (b) instruments in English (with French versions if possible); (c) all assessment instruments, the oldest and the most recent. The investigation ended in February 2013.ResultsTwelve unidimensional instruments were identified with only one of them based on a self-administered survey (MAP-SR). The number of items included is from 6 (SDS) to 25 (SANS). The fastest instrument is the HEN (5–10 min) and the longest is the SANS (30 min). The MASS needs an evaluation by another person (family or care-giver). Most instruments need to be handled and take place during a semi-structured or structured psychiatric interview. The SANS allows an assessment of the most important number of negative domains (11 domains). On the other side, we have the MAP-SR (3 domains). The most frequently evaluated domains are emotional blunting, alogia, social withdrawal, anhedonia and avolition. On the other side, we have mood and thought disorders. Only SDS allows to distinguish the primary and secondary negative symptoms.DiscussionThe oldest instruments (SANS, NSA-16, SDS) are more complicated to handle and to use. The SANS is the most complete instrument but there are more recent instruments which are easier to use and handle (BNSS, CAINS). Using a self-evaluation survey, MAP-SR is judicious as this type of evaluation is reliable. However, in this case, the assessment covers only a limited part of the negative symptoms.ConclusionDespite some progress in the definition, assessment and treatment of negative symptoms and despite new scales further instruments which are easy to use in clinical practice and integrating the patient's self-report are needed.     

Oral Communications

In this article, the knee instruments and rating scales that are designed to measure outcomes are revised. Although the International Knee Documentation Committee Subjective Knee Form can be used as a general knee measure, no instrument is currently universally applicable across the spectrum of knee disorders and patient groups. Clinicians and researchers looking to use a patient-based score for measurement of outcomes must consider the specific patient population in which it has been evaluated. The Western Ontario and McMaster Universities Osteoarthritis Index is recommended for the evaluation of treatment effect in persons with osteoarthritis (OA). This is a generic health status questionnaire that contains 36 items, is widely used, and easy to complete. The Knee Injury and Osteoarthritis Outcome Score (KOOS) questionnaire evaluates the functional status and quality of life (QoL) of patients with any type of knee injury who are at increased risk of developing OA; i.e., patients with anterior cruciate ligament (ACL) injury, meniscus injury, or chondral injury. So far, the KOOS questionnaire has been validated for several orthopedic procedures such as total knee arthroplasty, ACL reconstruction, and meniscectomy. The utilization of QoL questionnaires is crucial to the adequate assessment of a number of orthopedic procedures of the knee. The questionnaires are generally well accepted by the patients and open up new perspectives in the analysis of prognostic factors for optimal QoL of patients undergoing knee surgery.     

Robotic high para-aortic lymph node dissection with high port placement using same port for pelvic surgery in gynecologic cancer patients

ObjectiveThis study reports our initial experience of robotic high para-aortic lymph node dissection (PALND) with high port placement using same port for pelvic surgery in cervical and endometrial cancer patients.MethodsBetween July 2013 and January 2014, we performed robotic high PALND up to the left renal vein during staging surgeries. With high port placement and same port usage for pelvic surgery, high PALND was successfully performed without repositioning the robotic column. All data were registered consecutively and analyzed retrospectively.ResultsAll patients successfully underwent robotic high PALND, followed by hysterectomy and pelvic lymph node dissection. Median age was 45 years (range, 39 to 51 years) and median body mass index was 22 kg/m² (range, 19.3 to 23.1 kg/m²). Median operative time for right PALND and left PALND was 37 minutes (range, 22 to 65 minutes) and 44 minutes (range, 36 to 50 minutes), respectively. Median number of right and left para-aortic lymph node by pathologic report was 12 (range, 8 to 15) and 13 (range, 5 to 26).ConclusionWith high port placement and one assistant port, robotic high PALND with the same port used in pelvic surgery is feasible to non-obese patients.     

Reliability and validity of the Japanese version of the Biological Rhythms Interview of assessment in neuropsychiatry-self report for delayed sleep-wake phase disorder

ObjectiveThe Biological Rhythms Interview of Assessment in Neuropsychiatry (BRIAN) might be applicable for assessing delayed sleep-wake phase disorder (DSWPD). We aimed to investigate the reliability and validity of the Japanese version of the BRIAN self-report (J-BRIAN-SR) in DSWPD patients and determine a cutoff score to identify the presence of the disorder.MethodsWe enrolled 60 newly diagnosed DSWPD outpatients and 64 age-matched healthy controls. We used Cronbach's alpha for internal reliability to evaluate J-BRIAN-SR. We confirmed the reliability of the A test and re-test using Pearson's correlation coefficient in the controls. We used confirmatory factor analysis to evaluate the factor structure of J-BRIAN-SR and referenced the Morningness-Eveningness Questionnaire (MEQ) to check concurrent validity. We analyzed the receiver operating characteristic curve (ROC) to determine the J-BRIAN-SR cutoff point for the presence of DSWPD.ResultsThe 18-component scores of the J-BRIAN-SR had an overall reliability coefficient (Cronbach's alpha) of 0.82. We confirmed a high test-retest reliability using an intraclass correlation coefficient (r = 0.84). The correlation between J-BRIAN-SR and MEQ was 0.38 (p = 0.003). The J-BRIAN-SR that we extracted by exploratory factor analysis consisted of three factors. A score of 40 points provided a sensitivity of 80.0% and a specificity of 75.6% for the positivity of DSWPD.ConclusionsThe results of the present study revealed that J-BRIAN-SR is a valid and reliable instrument for screening and evaluating the severity of DSWPD. Our findings will be useful to physicians and patients in Japan and those in clinical settings.     

Translation and validation of the clinical learning environment,supervision and nurse teacher scale (CLES + T) in Croatian language

Clinical practice is essential to nursing education as it provides experience with patients and work environments that prepare students for future work as nurses. The aim of this study was to translate the “Clinical Learning Environment, Supervision and Nurse Teacher” questionnaire in Croatian language and test its validity and reliability in practice. The study was performed at the Faculty of medicine, Josip Juraj Strossmayer University of Osijek, Croatia in April 2014. The translated questionnaire was submitted to 136 nursing students: 20 males and 116 females. Our results reflected a slightly different factor structure, consisting of four factors. All translated items of the original constructs “Supervisory relationship”, “Role of nurse teacher” and “Leadership style of the ward manager” loaded on factor 1. Items of “Pedagogical atmosphere on the ward” are distributed on two factors (3 and 4). The items of “Premises of nursing on the ward” loaded on factor 2. Three items were identified as problematic and iteratively removed from the analysis. The translated version of the aforementioned questionnaire has properties suitable for the evaluation of clinical practice for nursing students within a Croatian context and reflects the specifics of the nursing clinical education in this country.
