Ambulatory Flash Glucose Monitoring Device Detects Hypoglycemia and Time in Range in Children and Adolescents of Type 1 Diabetes Mellitus

Objective: The mainstay of diabetes control and management is glucose monitoring (GM). Improving glycemic control and decreasing glycemic variability is important to prevent microvascular complications of diabetes. Adherence to GM is a challenge in pediatric type 1 diabetes mellitus (T1DM) patients. Furthermore, nighttime hypoglycemia (NTH) is a common complication of diabetes management; prevention and treatment of which is essential to improve quality of life. We aim to study the impact of flash GM device (FGMD) in detecting NTH and time in range (TIR) in children and adolescents of T1DM. Materials and Methods: This was a prospective observational study. Twenty children and adolescents of T1DM from North India, with mean age (range) of 7.15 years (3–13), were enrolled and applied FGMD. Episodes of NTH and average TIR were analyzed during one sensor application, i.e., 14 days. Results: The proportion of patients developing NTH after 14 days of insertion of device was 15 (75%) and 5 (25%) patients did not. The mean (standard deviation) duration of NTH in 24 h was 101.35 (136.02) min. The mean (range) percentage of TIR of our study subjects was 32.03% (0–61). Conclusion: Flash monitoring is a useful tool to improve adherence to GM, detecting hypoglycemia (diurnal and nocturnal) and TIR in children and adolescents with T1DM.

Comparative study between misoprostol and lidocaine before intrauterine contraceptive device insertion

Background Intrauterine contraceptive device (IUCD) is a safe, extremely effective and long-acting reversible contraceptive method. Misoprostol has definite to be a very pliable and adequate drug because its composition as a tablet that is stable and may be delivered orally, rectally or vaginally, and through the sublingual route. Lidocaine is a common local anesthetic and antiarrhythmic drug. Aims The objective of the present study was to compare between sublingual administration of misoprostol and lidocaine spray prior to IUCD insertion. Patients and methods This randomized controlled clinical trial was conducted at Department of Family Planning at Tanta University Hospital from February 2021 to March 2022. The study included 150 women into three groups each of them had 50 women. Results The pain scores during IUCD insertion and during uterine sounding were lower in group A, B. There was nonhuge distinction between both groups regarding insertion result (failed, easy or difficult insertion). There was nonhuge distinction between sublingual misoprostol and lidocaine spray regarding Visual Analogue Scale during sounding the uterus and during IUCD insertion. There was nonhuge distinction between studied groups as regard of medication related side effect except misoprostol group significant increase abdominal cramps. Conclusions The study concluded that the use of sublingual misoprostol and lidocaine before IUCD insertion reduces Visual Analogue Scale scores (pain scores) during sounding the uterus and during IUCD insertion.

Increasing utilization of intrauterine device insertion at hysteroscopic endometrial evaluation for patients with endometrial hyperplasia

PurposeTo examine the utilization and characteristics related to the use of hysteroscopy at the time of endometrial evaluation for endometrial hyperplasia in the outpatient surgery setting.MethodsThis cross-sectional study queried the Healthcare Cost and Utilization Project’s Nationwide Ambulatory Surgery Sample. The study population was 3218 patients with endometrial hyperplasia who underwent endometrial evaluation from January 2016 to December 2019. Performance and clinical characteristics of hysteroscopic endometrial evaluation were assessed with multivariable binary logistic regression models.ResultsA total of 2654 (82.5%) patients had hysteroscopic endometrial tissue evaluation. Patients with postmenopausal bleeding, heavy menstrual bleeding, and polycystic ovary syndrome were more likely to undergo hysteroscopic endometrial evaluation in multivariable analysis (all, adjusted-P < 0.001). Uterine injury occurred in 4.9 per 1000 hysteroscopic endometrial evaluations; none had uterine injury in the non-hysteroscopy cohort. Among the 2654 patients who had hysteroscopic endometrial evaluation, 106 (4.0%) patients had intrauterine device insertion at surgery, and the utilization increased from 2.9 to 5.8% during the study period (P-trend < 0.001). Younger age, more recent year surgery, and obesity were independently associated with increased utilization of intrauterine device insertion at hysteroscopic endometrial evaluation (all, adjusted-P < 0.05). Among 2023 reproductive-age patients with endometrial hyperplasia, 1666 (82.4%) patients underwent hysteroscopic endometrial evaluation. On multivariable analysis, patients with heavy menstrual bleeding were more likely to have hysteroscopic endometrial evaluation (adjusted-P < 0.05). Intrauterine device insertion increased from 3.7% in 2016 to 8.0% in 2019 (P-trend = 0.007).ConclusionThis nationwide analysis suggests that the insertion of intrauterine devices at the time of hysteroscopic endometrial tissue evaluation for endometrial hyperplasia is increasing among reproductive-age population.

Cervical ripening balloon compared with vaginal dinoprostone for cervical ripening in obese women at term: A prospective cohort study.

To evaluate vaginal delivery in obese women who underwent cervical ripening at term using a dinoprostone vaginal insert or a cervical ripening balloon (CRB), and to assess maternal and neonatal morbidity according to the method. A prospective cohort study including obese women with a live singleton fetus in cephalic presentation who required cervical ripening at term (≥37 weeks) for maternal and/or fetal disease using a dinoprostone vaginal insert or a CRB. The primary outcome was vaginal delivery. Secondary outcomes were a favorable cervix (Bishop score >6) after 24 h, the time from device insertion to delivery, and composite maternal and neonatal morbidity. In total, 135 consecutive women were analyzed (107 CRB, 79.3%; 28 dinoprostone vaginal insert, 20.7%). Vaginal delivery (86 [80.4%] after CRB vs 19 [67.9%] after dinoprostone vaginal insert; P = 0.248), favorable cervix within 24 h after device placement (52 [48.6%] vs 17 [60.7%]; P = 0.264), and maternal morbidity (12 [11.2%] vs 4 [14.3%]; P = 0.646) were similar between the groups. The time from device insertion to delivery also did not differ between the groups. Neonatal morbidity was significantly higher after the dinoprostone vaginal insert (11 [39.3%] vs 20 [18.7%]; P = 0.030). Cervical ripening using the dinoprostone vaginal insert, compared with the CRB, was significantly associated with neonatal morbidity (adjusted odds ratio 4.00, 95% confidence interval 1.34-12.5), but not with maternal morbidity (adjusted odds ratio 1.23, 95% confidence interval 0.30-4.38). Vaginal delivery, a favorable cervix after 24 h, the time from device insertion to delivery, and maternal morbidity did not significantly differ between the CRB and the dinoprostone vaginal insert for cervical ripening in obese women at term. Nevertheless, neonatal morbidity was significantly associated with the dinoprostone vaginal insert, compared with the CRB, among obese women who required cervical ripening at term.

Prophylactic Antibiotics before Gynecologic Surgery: A Comprehensive Review of Guidelines.

Surgical site infections (SSIs) refer to infections in the incision, organ, or postoperative space. As common healthcare-associated infections, SSIs correlate with prolonged hospital stay, additional procedures, ICU stay, and higher mortality rates. Around 8-10% of gynecologic surgery patients may experience infectious complications, influenced by microbial contamination, surgical nature, and patient factors. The goal of this narrative review is to compare and merge recommendations from globally published guidelines concerning the utilization of antibiotics in the perioperative phase. A comparative descriptive/narrative review of the guidelines issued by the American College of Obstetrics and Gynecology (ACOG), Society of Obstetricians and Gynecologists of Canada (SOGC), Royal College of Obstetricians and Gynecologists (RCOG), National Institute for Health and Care Excellence (NICE), Royal Australian and New Zealand College of Obstetricians and Gynecologists (RANZCOG), European Society of Gynecologic Oncology (ESGO), Société Française d' Anésthesie et de Réanimation (SFAR), Spanish Society of Infectious Diseases and Clinical Microbiology (SEIMC), and Hellenic Society of Obstetrics and Gynecology (HSOG) was conducted. For hysterectomy, first/second-generation cephalosporins are suggested, with metronidazole as an option. Laparoscopy without entering the bowel or vagina typically does not require prophylaxis. Uterine evacuation and hysteroscopy may involve doxycycline or azithromycin based on risk factors, whereas, for vulvectomy, cefazolin is recommended. Urogynecology procedures may include cefazolin with metronidazole. In cases of penicillin allergy, cephalosporins are suggested, and, for obese patients, adjusted doses are advised. Additional doses may be needed for prolonged procedures or excessive blood loss. Timing recommendations are 15-60 min before incision, adjusting for specific antibiotics. Clear indications exist for certain surgeries like hysterectomy, termination of pregnancy, and urogynecologic procedures. Conversely, procedures such as intrauterine device insertion, hysteroscopy, and laparoscopy typically do not necessitate antibiotic prophylaxis. For several other procedures, the evidence is inconclusive, while considering dose, timing, and indications can mitigate infectious complications and provide benefits for the healthcare system.

Difficult mask ventilation: An objective criterion

Effective mask ventilation plays a critical role in safe management of airway before intubation or after failed intubation. Mask ventilation (MV) is the primary technique of ventilation before tracheal intubation or insertion of any airway device. Its most unique role however, is as a rescue technique for ventilation should tracheal intubation fail or prove difficult. The ability to establish adequate MV has, therefore, become a major branch point in any difficult airway algorithm. Despite it being an important skill, MV has received little attention in the extensive body of literature and book chapters addressing airway management when compared to laryngoscopy and intubation. At present, there is no standard definition for Difficult Mask Ventilation (DMV) that is based on precise and objective criterion. The authors propose a simple objective criterion to categorize difficult mask ventilation based on the best monitoring parameters.

A novel guide device for pedicle screw insertion using three-dimensional preoperative planning in open lumbar spinal surgery: a comparative retrospective study

ABSTRACT Objective Pedicle screw stabilization (PSS) surgeries for spinal instability are still the most effective treatment approach. The use of preoperative planning can minimize the complications related to transpedicular screw (TPS) misplacement. The study aimed to evaluate the surgical outcomes of a guide device developed to improve the accuracy of the free-hand technique using three-dimensional planning in PSS. Patients and methods Patients with degenerative spinal diseases who underwent open PSS between 2019 and 2022 were evaluated retrospectively. FG group included patients who were operated on using the fluoroscopy alone with preoperative two-dimensional planning. AFG group included patients who were operated on using a guide advice-assisted technique with preoperative 3DP. Between-group comparisons were performed. Results A total of 143 patients with a mean age of 59.6 years were included in the study. 71 patients were assessed in the FG group and 72 patients in the AFG group. Between-group comparisons regarding demographics, etiologies, radiation exposure, and functional improvements showed no significant differences (p > 0.05). Although the accuracy of TPSs positioning was 94.2% and 96.5% in the 2DG and 3DG, the difference between the groups was not statistically significant. The statistically significant differences regarding the upper-level facet joint violation and pedicle breach rates were lower in the AFG group (p < 0.0001; X2 = 19.57) and (p < 0.0001; X2 = 25.3), respectively. Conclusion Using a guide device associated with preoperative 3PD reduced the upper-level facet joint violation and pedicle breach rates in open PSS surgeries performed by free-hand technique for degenerative spinal diseases.

Differing Approaches to Pain Management for Intrauterine Device Insertion and Maintenance: A Scoping Review.

Intrauterine devices (IUDs) are considered a reliable contraceptive option for women,but they can come with side effects. There is a disconnect in standard guidelines for IUD insertion within and without the U.S. The objective of this review was to address a gap in the literature regarding official procedures for pain management during IUD implantation.This scoping review was initiated using keywords to extract relevant articles from multiple databases: U.S. National Library of Medicine National Institutes of Health (PubMed), MEDLINE (Ovid), and Excerpta Medica dataBASE (EMBASE, Ovid). Initially, 457 articles were identified and after a rigorous screening and selection process, 37 articles were chosen to be further assessed to ascertain if they met the study's inclusion criteria. Those 37 articles were further evaluated fully to check for relevancy. From that process, 19 articles were chosen for the review, and all passed quality assessment evaluations using the JB Appraisal Tools. To best address the research question, the data from the 19 articles were divided into three categories: 1) circumstantial factors, 2) non-pharmacological methods, and 3) pharmacological methods. Circumstantially, women with previous vaginal deliveries experienced the lowest pain during the procedure, and nulligravid (never pregnant) women experienced the most pain. Lower pain scores were reported by lactating women compared to non-lactating. Black women experienced the most anticipated pain compared to other races. Regarding non-pharmacological methods, different insertion techniques, tools, and the use of a cold compress were found to not affect the level of pain during IUD insertion. Lastly, it was shown that pharmacological methods such as lidocaine gel, lidocaine paracervical block, and lidocaine combined with either diclofenac or prilocaine decreased pain scores at different time stamps of the procedure. Also, oral ketorolac and a vaginal combination of misoprostol and dinoprostone helped reduce pain.Findings from this scoping review revealed a lack of uniformity across practices when performing IUD insertions, possibly due to differences in procedures across circumstantial factors, non-pharmacological methods, and pharmacological methods. More research is needed to investigate the intricacies of pain with IUD insertion. Moving forward, especially following a potential increase in the use of IUDs after the reversal of Roe v. Wade, establishing this gap may lead to a more refined standardized protocol to mitigate pain with IUD insertions.

Balloon endoscopy-assisted endoscopic retrograde cholangiopancreatography for hepatolithiasis in patients with hepaticojejunostomy.

Balloon endoscopy-assisted endoscopic retrograde cholangiopancreatography (BE-ERCP) is an emerging procedure for pancreatobiliary diseases in patients with surgically altered anatomy. However, data on BE-ERCP for hepatolithiasis after hepaticojejunostomy (HJS) are still limited. Stone removal success, adverse events and recurrence were retrospectively studied in consecutive patients who underwent BE-ERCP for hepatolithiasis after HJS between January 2011 and October 2022. Subgroup analysis was performed to compare clinical outcomes between patients who had undergone HJS over 10 years before (past HJS group) and within 10 years (recent HJS group). A total of 131 patients were included; 39% had undergone HJS for malignancy and 32% for congenital biliary dilation. Scope insertion and complete stone removal were successful in 89% and 73%, respectively. Early adverse events were observed in 9.9%. Four patients (3.1%) developed gastrointestinal perforation but could be managed conservatively. Hepatolithiasis recurrence rate was 17%, 20% and 31% in 1-year, 3-year, and 5-year after complete stone removal. The past HJS group was the only risk factor for failed stone removal (odds ratio 10.4, 95% confidence interval 2.99-36.5) in the multivariable analysis. Failed scope insertion (20%) and failed guidewire or device insertion to the bile duct (22%) were two major reasons for failed stone removal in the past HJS group. BE-ERCP for hepatolithiasis was effective and safe in cases with HJS but the complete stone removal rate was low in the past HJS group. Recurrent hepatolithiasis was common and careful follow up study is needed even after complete stone removal.

The effect of virtual reality glasses applied during intrauterine device insertion on pain, anxiety and satisfaction: Randomized controlled study.

This study was carried out to determine the effect of the use of "virtual reality glasses," on anxiety, pain, and satisfaction level in order to reduce anxiety and pain during intrauterine device (IUD) insertion, which is a painful and stressful procedure for women and to divert attention to increase satisfaction. This randomized controlled study in the gynecology clinic of a state hospital with 80 women who were accepted to participate in the study. Data were collected using structured patient information form, numerical pain rating scale, state-trait anxiety inventory, patient satisfaction evaluation form, and virtual reality glasses. Post-procedural pain scores in the control group after IUD application were higher than post-procedural pain in the virtual reality group. Measurements of post-procedure anxiety in the control group were higher than measurements of post-procedural in the virtual reality group. Satisfaction levels of women with virtual reality glasses during IUD insertion were also found to be high. It was determined that the use of virtual reality glasses, one of the methods of distraction during IUD insertion, was effective in reducing pain and anxiety and increasing patient satisfaction.

(163) Is There a Place for Immediate 3-Component Prosthesis Implantation Following Priapism?

Abstract Introduction One of the most difficult challenges in prosthetic urology is the insertion of penile implants into corpora scarred from an episode of priapism. In cases of scarred penile cavernosal bodies, surgery becomes challenging even for experienced surgeons, as it can be very difficult to dilate the corpora. Objective Usually, the initial insertion of a malleable device is used as a temporary measure, to maintain the penile length and simplify the subsequent insertion of an inflatable one. So our objective is to decrease the number of surgeries from 2 to 1. Methods In this case, we dilated the corpora cavernosa initially with Metzenbaum scissors thoroughly and carefully. We placed the tip of the scissors at the outer side of each cavernous body (away from the urethra) and advanced it to the tip of the corpus cavernosum. Then, we used the cavernotomes Results Till now the prostheses are functional. We do believe that in certain cases, with the right choice of the patient, the implant of the IPP after priapism is a viable solution Conclusions Cavernotomes are a good option for dilating the fibrotic corpora. And it is safe Disclosure No.

(040) Anterolateral Thigh Flap Phalloplasty: Outcomes Following Genital Gender Affirmation Surgery

Abstract Introduction Genital gender affirmation surgery (gGAS) is a key part of the management of patients with gender dysphoria. The anterolateral thigh (ALT) free flap was proposed as an alternative to the more common radial forearm free flap (RFFP) phalloplasty due to the twin advantages of a more easily hidden scar and improved flexibility in the length of the flap. A pedicled variant of the ALT flap offers greater security of vascular supply for suitable patients, and if suitable and desired the flap can be formed with an integrated urethra, facilitating voiding while standing. Objective The aim of the study is to report the contemporary surgical and functional outcomes of ALT phalloplasty. Methods All individuals undergoing ALT flap phalloplasty for genital gender affirmation surgery (GAS) between 2009 and 2023 nationwide were included. Individuals were managed in accordance with the World Professional Association for Transgender Health (WPATH) Standards of Care version 7. Data were extracted from a prospectively collected single surgeon database and medical records. Functional outcomes were assessed by non-validated questionnaire. Statistical analysis included Mann-Whitney, chi-squared, Fisher’s exact and unpaired T tests. Results Surgical outcomes: A total of 87 patients were included in the study. More than half (45, 51.7%) had an integrated urethra. The median length of stay following surgery was six days (IQR 6-7). Eleven patients (12.6%) had a 30-day Clavien-Dindo 3b complication or greater. Three patients (3.4%) experienced total flap loss. A further three patients (3.4%) had partial flap loss. Three patients (3.4%) required a salvage phalloplasty later. Thirteen patients (out of 42, 31.0%) without an integrated urethra went onto have a free flap urethroplasty. Functional outcomes: Thirty-nine individuals (44.8%) completed the patient reported outcomes questionnaire. Most patients (77%) were generally satisfied with their phalloplasty. More than half (56%) with an erectile device used their phallus for penetrative intercourse, while one in five reported experiencing orgasm using their phallus alone. Following urethral lengthening, all respondents were able to void standing. There was no significant difference in mean satisfaction scores for those with an integrated urethra compared to those without (4.18/5 vs 3.82/5, p=.45), as well as between those with or without an erectile device, respectively (3.78/5 vs 4.10/5, p=.26). Conclusions This study is one of the largest single centre cohorts of ALT flap phalloplasty reported to date. It further supports the use of the ALT flap as one of the main genital GAS options for transmen. Over half of the patients studied had an integrated urethra, the gold standard for urethral lengthening. Patient reported functional outcomes were promising, with similar scores regardless of urethral lengthening or erectile device insertion. Disclosure No.

Leveraging Compliance to Design a Minimally Invasive, Expandable Interbody Cage Capable of Customized Anatomical Fit for Spinal Fusion Surgery

Abstract As spinal fusion surgery continues to transition to less invasive techniques, there remains an unmet need for ever smaller and more complex interbody cages to meet the unique needs of this difficult surgery. This work focuses on the hypothesis that this need can be met using the inherent advantages of compliant mechanisms in a way no previous device has. Deployable Euler Spiral Connectors optimized using a gradient based optimization algorithm were used as the foundation for a device that can stow to a very small size for device insertion then bilaterally deploy to a substantially larger device footprint. Additionally, a continuously adjustable lordotic angle was achieved using the same device so as to result in a customized anatomical fit while potentially reducing hospital inventory requirements. Several tests including finite element analysis, compression testing, shear testing, and deployment in a cadaver were performed as initial verification and validation that the concept device performs reasonably well under typical testing paradigms used for interbody cages.

Hematoma Prevention Using Tachosil (Fibrin Sealant) Patch during Insertion of Cardiovascular Implantable Electronic Devices without Suspending Antithrombotics: Three Case Reports

Patients undergoing insertion of cardiac implantable electronic devices often exhibit perioperative hemorrhagic complications. Perioperative antithrombotic management, which balances the risk of acute thrombosis and postoperative bleeding, is therefore important for these patients. In this case report, we present three cases of cardiovascular implantable electronic device (CIED) insertion. While the three patients each had different reasons for not discontinuing antithrombotic medications, they all needed CIEDs. During the CIED implantation procedures, a small incision was made on the pectoralis muscle region to obtain a small subcutaneous pocket, and Tachosil, a fibrin sealant patch, was inserted below and above the inserted device. The patients showed no pocket hematoma formation or any hemorrhagic complications. We thus concluded the application of a fibrin sealant patch could be an option for perioperative anticoagulation management without interruption of anticoagulants and antiplatelets.

Non-pyrogenicity and biocompatibility of parylene-coated magnetic bead implants.

Clinical grade magnetic bead implants have important applications in interfacing with the human body, providing contactless mechanical attachment or wireless communication through human tissue. We recently developed a new strategy, magnetomicrometry, that uses magnetic bead implants as passive communication devices to wirelessly sense muscle tissue lengths. We manufactured clinical-grade magnetic bead implants and verified their biocompatibility via intramuscular implantation, cytotoxicity, sensitization, and intracutaneous irritation testing. In this work, we test the pyrogenicity of the magnetic bead implants via a lagomorph model, and we test the biocompatibility of the magnetic bead implants via a full chemical characterization and toxicological risk assessment. Further, we test the cleaning, sterilization, and dry time of the devices that are used to deploy these magnetic bead implants. We find that the magnetic bead implants are non-pyrogenic and biocompatible, with the insertion device determined to be safe to clean, sterilize, and dry in a healthcare setting. These results provide confidence for the safe use of these magnetic bead implants in humans.

A single-institutional experience with 36 children less than 5 kilograms supported with the Berlin Heart: Comparison of congenital versus acquired heart disease.

We reviewed outcomes in all 36 consecutive children <5 kg supported with the Berlin Heart pulsatile ventricular assist device at the University of Florida, comparing those with acquired heart disease (n = 8) to those with congenital heart disease (CHD) (n = 28). The primary outcome was mortality. The Kaplan-Meier method and log-rank tests were used to assess group differences in long-term survival after ventricular assist device insertion. T-tests using estimated survival proportions were used to compare groups at specific time points. Of 82 patients supported with the Berlin Heart at our institution, 49 (49/82 = 59.76%) weighed <10 kg and 36 (36/82 = 43.90%) weighed <5 kg. Of 36 patients <5 kg, 26 (26/36 = 72.22%) were successfully bridged to transplantation. (The duration of support with ventricular assist device for these 36 patients <5 kg was [days]: median = 109, range = 4-305.) Eight out of 36 patients <5 kg had acquired heart disease, and all eight [8/8 = 100%] were successfully bridged to transplantation. (The duration of support with ventricular assist device for these 8 patients <5 kg with acquired heart disease was [days]: median = 50, range = 9-130.) Twenty-eight of 36 patients <5 kg had congenital heart disease. Eighteen of these 28 [64.3%] were successfully bridged to transplantation. (The duration of support with ventricular assist device for these 28 patients <5 kg with congenital heart disease was [days]: median = 136, range = 4-305.) For all 36 patients who weighed <5 kg: 1-year survival estimate after ventricular assist device insertion = 62.7% (95% confidence interval = 48.5-81.2%) and 5-year survival estimate after ventricular assist device insertion = 58.5% (95% confidence interval = 43.8-78.3%). One-year survival after ventricular assist device insertion = 87.5% (95% confidence interval = 67.3-99.9%) in acquired heart disease and 55.6% (95% confidence interval = 39.5-78.2%) in CHD, P = 0.036. Five-year survival after ventricular assist device insertion = 87.5% (95% confidence interval = 67.3-99.9%) in acquired heart disease and 48.6% (95% confidence interval = 31.6-74.8%) in CHD, P = 0.014. Pulsatile ventricular assist device facilitates bridge to transplantation in neonates and infants weighing <5 kg; however, survival after ventricular assist device insertion in these small patients is less in those with CHD in comparison to those with acquired heart disease.
