Pain relief by continuous intraperitoneal nebulization of ropivacaine during gynecologic laparoscopic surgery--a randomized study and review of the literature

STUDY OBJECTIVE: To evaluate the efficacy of intraperitoneal nebulization of ropivacaine on pain relief during and after gynecologic laparoscopic procedures including a review of the literature. DESIGN: Double-blinded, randomized, controlled, clinical trial (Canadian Task Force classification I). SETTING: University hospital ambulatory gynecoendoscopic department. PATIENTS: Forty patients (20 patients in each arm) undergoing elective gynecologic same-day outpatient laparoscopic surgery including unilateral/bilateral salpingo-oophorectomy or unilateral/bilateral ovarian cystectomy. INTERVENTIONS: The study group received 10 mL of 1% ropivacaine and the control group received 10 mL of sterile water by intraperitoneal nebulization. During surgery, vital signs were recorded and summarized. Postoperatively patients were followed up for 24 hours including visual analog scale scores and analgesic use. MEASUREMENTS AND MAIN RESULTS: No significant differences existed between the groups during surgery and at the recovery department in terms of arterial blood pressure (p = .42) or heart rate (p = .60). Regarding postoperative analgesia, no difference existed between the groups in terms of morphine consumption (p = .52) or other analgesics (p = .53). No significant difference existed between the groups in postoperative visual analog scale scores including visceral, abdominal wall, and shoulder pain during rest and during cough at the different time frames (30, 60, and 120 minutes and 6 and 24 hours after surgery). CONCLUSION: Our study is the first to examine the effects of intraperitoneal nebulization of ropivacaine throughout laparoscopic gynecologic procedures on patients undergoing general anesthesia. Nebulization of 100 mg of ropivacaine under our specific regimen of anesthesia does not improve patients' outcome in terms of intraoperative and postoperative pain along with consumption of analgesics. Further research with other regimens is required.     

Whole genome association studies for genes affecting alcohol dependence

We applied the transmission/disequilibrium test (TDT) for sibs (S-TDT) and for families with one parent (1-TDT), to the Collaborative Study on the Genetics of Alcoholism data set. The combined test is used to screen the whole genome to locate genes responsible for alcohol dependence. This analysis supports the previous finding that the region close to GABRB1 on chromosome 4 might be associated with alcohol dependence. The regions close to D6S474 and D11S1998 are also of particular interest. We found segregation distortion at the GR1K1 locus. The segregation distortion might be due to the binning method used in genotyping at this locus.     

Successful Topical Application of Botulinum Toxin After Microneedling Versus Microneedling Alone for the Treatment of Atrophic Post Acne Scars: A Prospective,Split-face,Controlled Study

BackgroundAcne scars are a source of cosmetic concern for most of the patients.ObjectiveWe sought to compare the clinical efficacy and safety of topical botulinum toxin A (BTX-A) application immediately after microneedling (Mn) versus Mn with saline in the treatment of atrophic acne scars.MethodsForty patients with atrophic acne scars (rolling, boxcar, and mixed types) were enrolled in a split-face study; microneedling was performed on both sides of the face followed by an application of topically diluted botulinum toxin on one side (Side A) and saline on the other (Side B) for two sessions both two weeks apart. Evaluation was done at baseline, two and four weeks after the session. Follow-up was performed after six months. The assessments included blinded clinical assessment and patient’s satisfaction.ResultsAfter the treatment, acne scars in (Side A) showed 70 percent overall improvement versus zero percent in Side B (P<0.0001). A statistically highly significant reduction of acne scars severity occurred in (Side A) (P=0.0008). Patient’s satisfaction was higher in (Side A) (P<0.0001). No serious side effects were reported.ConclusionMicroneedling delivery of BTX-A could be simple, safe, and innovative modality improving the appearance and decrease the depth of atrophic acne scars.     

Suicidality Over the First 5 Years of Psychosis: Does Extending Early Intervention Have Benefits?

Objective:We aimed to investigate whether individuals with first-episode psychosis (FEP) receiving extended early intervention (EI) were less likely to experience suicidal ideation and behaviors than those transferred to regular care after 2 years of EI. Another objective was to examine the 5-year course of suicidality in FEP.Methods:We conducted a secondary analysis of a randomized controlled trial where 220 patients were randomized after 2 years of EI to receive extended EI or regular care for the subsequent 3 years. Suicidality was rated using the Brief Psychiatric Rating Scale. Linear mixed model analysis was used to study time and group effects on suicidality.Results:Extended EI and regular care groups did not differ on suicidality. There was a small decrease in suicidality over time, F(7, 1038) = 1.84, P = 0.077, with an immediate sharp decline within a month of treatment, followed by stability over the remaining 5 years. Patients who endorsed suicidality at entry (46.6%) had higher baseline positive, negative, and depressive symptoms. The 5-year course fell in 3 groups: never endorsed suicidality (33.9%), endorsed suicidality at low-risk levels (43.1%), and endorsed high-risk levels (23.0%). The high-risk group had a higher proportion of affective versus nonaffective psychosis diagnosis; higher baseline positive and depressive symptoms; higher 5-year mean depression scores, and fewer weeks of positive symptom remission over the 5-year course.Conclusions:The first month of treatment is a critical period for suicide risk in FEP. Although early reductions in suicidality are often maintained, our findings make the case for sustained monitoring for suicide risk management.     

Modified technique to extract malpositioned or migrated self-expanding stents from the esophagus and stomach

Background and Aim:  Various methods have been used to remove self expandable stents (SES) because of either malposition or migration. The main difficulties encountered in such situations are the anatomic obstacle of the lower and upper esophageal sphincters as well as risk of mucosal injury during removal.
Methods:  We describe a modified approach using an esophagogastroduodenoscope (EGD) in combination with a foreign body hood protector, rat tooth forceps and snare allowing for successful SES removal from the upper gastrointestinal tract in four cases.
Results:  In all cases, the SES were successfully removed from upper gastrointestinal tract using this technique. No complications were noted after extraction.
Conclusion:  The foreign body hood protector combined with rat tooth forceps/snare technique is a safe and effective alternative to previously described methods for extraction of SES from the upper gastrointestinal tract. This method may be applicable for the removal of other such objects within the endoscope's reach.     

Laparoscopy following peritoneal entry during transanal endoscopic microsurgery may increase the safety and maximize the benefits of the transanal excision

Background

Peritoneal entry (PE) during transanal endoscopic microsurgery (TEM) for tumors of the upper rectum is not an uncommon complication. The suture line of the rectal defect performed for PE is not devoid of leaks. Diagnostic laparoscopy after PE enables visualization and testing of the suture line. Here, we report the outcome of patients undergoing laparoscopy for PE following TEM.

Methods

Data pertaining to patients undergoing laparoscopy for PE following TEM between 2004 and 2013 were retrospectively collected.

Results

One hundred and forty-one TEM procedures were performed, and 19 (13 %) with PE were included. The mean age was 68.1 ± 10.6 years, mean distance from the anal verge 12.5 ± 2 cm, and mean tumor size 2 cm. Lesions were located in the lateral wall (n = 14), anteriorly (n = 4), and posteriorly (n = 1). Indications for TEM were: adenoma (n = 13), indeterminate margins after polypectomy (n = 4, a submucosal lesion (n = 1), and a T1N0 adenocarcinoma (n = 1). In all patients, the rectal wall defect was closed primarily. Twelve patients underwent additional laparoscopy and suture line leak testing. In one patient, a small leak was detected which was repaired laparoscopically. In another, a hematoma of the suture line was observed and a drain was left in place. The mean operative time was 109 min (range 80–135 min) for TEM and 33 min (range 22–45 min) for laparoscopy. A diverting ileostomy was fashioned in one patient on postoperative day 3 after TEM without laparoscopy. No other major complications were observed.

Conclusions

Laparoscopy after PE during TEM permits visualization and testing of the suture line. It is not associated with increased morbidity, and it may increase the safety of TEM.

     

Critical study of echocardiography in mitral cardiopathies]

The importance of the echocardiogram in a study of mitral disorders has been analysed by examining 107 echocardiograms set against a clinical examination, an investigation of haemodynamic function (57), left-sided angiography (42), and/or examination at the time of operation (40). This study confirms the great diagnostic value of the echocardiographic findings in mitral stenosis (56 patients): the amplitude DE, the slope EF, the percentage of mid-diastolic closure, the echo from the valves, and the dimension of the left atria (P less than 0.001). This association remains valid if there is mitral incomptence as well as stenosis, or if there is also an aortic lesion, provided all the parameters are used. The degree of stenosis of the mitral orifice cannot be determined with sufficient certainty to allow surgical exploration to be undertaken solely on echocardiographic results, however the patients are selected (sinus rhythm, absence of calcification, mobile valve...). The echocardiographic diagnosis of the 17 cases of mitral incompetence was incomplete (except for rupture of the chords); the volume of the regurgitation is poorly appreciated.     

Management of high-grade squamous intraepithelial lesion patients with positive margin after LEEP conization: A retrospective study

To explore the optimal way to manage patients with high-grade squamous intraepithelial lesion (HSIL) and positive margin by identifying the risk factors for its recurrence and residue.A retrospective study was conducted on 267 cases of a pathologically confirmed HSIL with positive margin following conization by loop electrosurgical excisional procedure (LEEP) between January 2010 and December 2015. One hundred two cases were selected for regular follow-up every 6 months, and 165 cases were selected for a second surgery (repeat cervical conization or hysterectomy) within 3 months of initial LEEP. We analyzed the association between recurrent or residual diseases and these factors: age, menopausal status, ThinPrep cytologic test (TCT) results, high-risk human papillomavirus (HR-HPV) infection, pathological grades of the margin, number of involved margins, and glandular involvement.The recurrence rate among 102 cases who underwent follow-up was 17.6% (18/102). The factors: atypical squamous cells of undetermined significance cannot exclude HSIL (ASC-H) or higher lesions in the pre-LEEP TCT (P = .038), persistent HR-HPV infection at the 6th month post-LEEP (P = .03), HSIL-positive margin (P = .003), and multifocal-involved margin (P = .002) were significantly associated with recurrent disease, while age, menopause, and pre-LEEP HR-HPV infection were not associated with recurrent disease (P > .05). The residual rate among 165 patients who underwent a second surgery was 45.5% (75/165), of which 15 cases were residual cervical cancer. The factors: menopause (P = .02), ≥ASC-H in pre-LEEP TCT (P = .04), pre-LEEP HR-HPV infection (P = .04), ≥HSIL-positive margin (P < .001), and multifocal-involved margin (P < .001) significantly increased the risk of residual disease. No correlation existed between residual disease and age or glandular involvement (P > .05).For patients with a positive margin after LEEP, regular follow-up or second surgery should be selected according to fertility requirement and pathological characteristics of the positive margin, as well as TCT and HR-HPV infection condition.
