Introduction During the novel coronavirus disease 2019 pandemic, health care workers experienced facial problems from prolonged use of N95 masks, including skin irritation, pigmentation changes, and contact dermatitis. We assessed the use of hydrocolloid dressing versus dimethicone cream to prevent skin breakdown among military health care workers while wearing an N95. Materials and Methods Participants were recruited using convenience and snowball sampling in this nonblinded, randomized, cross-over study with 2 active treatments, hydrocolloid dressing and dimethicone cream, across 3 time points. The skin was assessed using photographs and subepidermal moisture scanner (SEM). N95 seal integrity was assessed using qualitative fit test. Institutional review board approval was obtained from the Madigan Army Medical Center Institutional Review Board. Results Among the 73 participants, wearing an N95 alone versus with dimethicone cream or hydrocolloid dressing caused more adverse skin reactions. There were no significant differences in qualitative fit test failure rate between groups. Participants experienced minimal to no dizziness, loss of energy/tiredness/fatigue, claustrophobia, shortness of breath, difficulty breathing, and dry or itchy eyes. For all interventions, wearing an N95 did not interfere with participants' concentration, verbal communication, hearing, vision, and, importantly, delivery of care. Conclusions Using a skin protectant with an N95 may prevent adverse skin reactions while preserving health care workers' ability to safely and competently care for patients in routine and pandemic conditions.

Background and Aim: Diagnostic performance of esophagogastroduodenoscopy (EGD) may be compromized due to adherent mucus and foam. In this study, we aimed at assessing the impact of premedication on mucosal visibility during endoscopy. Methods: This is a double-blinded (patient and investigator), randomized trial conducted at a tertiary care centre. Patients were randomized into four groups: A (water), B (simethicone [S]), C (N-acetyl cysteine [NAC]), D (S + NAC). Premedication solutions were administered 10-30 minutes before endoscopy and mucosal visibility graded from 1 (best) to 4 (worst) (1 best, 4 worst). Total mucosal visibility scores (TMVS) from six sites ranged from 6 (best) to 24 (worst) points. The primary outcome of study was comparison of TMVS between simethicone and combination (S + NAC) premedication groups. Secondary outcomes were adverse events and impact of endoscopy timing on TMVS. Results: Total 800 patients (39 years, 68.8% males) were randomized into four groups. Median TMVS were significantly lower in groups B (7 [6-8]) and D (8 [6-9]) as compared to A (11 [9-13]) and C (10 [8-12]). Proportion of cases with adequate gastric mucosal visibility (score < 7) was 26% in group A, 71% in group B, 36% in group C and 79% in group D. There was no difference in TMVS in groups A and C (p = 0.137). TMVS were significantly lower in late (> 20-30 minutes) vs. early (10–20 minutes) endoscopy sub-group (8 [7–11] vs, 9 ([7–11], p = 0.001). However, TMVS were similar between group B and group D in early endoscopy group (p = 0.451). There was no significant difference in the lesion detection rate among the different premedication drugs (p > 0.05). Conclusions: Premedication with simethicone or combination (simethicone and NAC) significantly improves mucosal visibility during EGD. If early endoscopy is indicated, simethicone provides similar mucosal visibility and may be an effective alternative to combined premedication. Trial registration: NCT05951712.

Abstract This study aimed to assess the impact of adding pancreatin (a pancreatic enzyme derivative) to standard treatment on patients diagnosed with Irritable Bowel Syndrome (IBS) and Type 2 Diabetes Mellitus (T2DM). IBS and T2DM frequently coexist, leading to significant gastrointestinal symptoms and a decrease in quality of life. Gastrointestinal symptoms arising in T2DM patients present challenges in management for both clinicians and patients. Standard treatments may not fully address these symptoms. Recent studies suggest that pancreatic enzyme replacement therapy may offer additional benefits. This study investigates whether adding pancreatin to standard treatment can improve gastrointestinal outcomes in this patient population. Conducted as a prospective observational study, the research involved patients diagnosed with IBS according to Rome IV criteria and having concomitant T2DM. The patients were divided into two groups: one receiving standard dual treatment (otilinium bromide + simethicone) and the other receiving a triple therapy including a pancreatin derivative in addition to the standard treatment. Various clinical scores and measurements, including Visual Analog Scale (VAS), Bristol Stool Chart (BSC), Irritable Bowel Syndrome-Severity Scoring System (IBS-SSS), and Irritable Bowel Syndrome Quality of Life Instrument (IBS-QOL), were assessed before and after treatment. The study comprised 121 patients, with a median age of 41 years (interquartile range [IQR] 38–48), of whom approximately 70.2% were female. Fifty-eight patients (47.9%) received dual therapy, while sixty-three patients (52.1%) received triple therapy. Before treatment, both groups exhibited similar pre-treatment Bristol stool scale results: normal (39.7% and 49.2%) and constipation (37.9% and 31.7%) in the dual and triple therapy subgroups, respectively (p > 0.05). Post-treatment, the triple therapy group showed a significantly higher proportion of normal cases on the Bristol stool scale (82.5%) compared to the dual therapy group (44.8%) (p 0.05 for all parameters). The findings suggest that adding pancreatin to standard therapies significantly enhanced the quality of life for patients with both IBS and T2DM, demonstrating improvements across various symptom measurements and indicating the potential benefits of this supplementary therapy in managing gastrointestinal symptoms in this population. Further studies are warranted to explore its broader clinical implications and mechanisms of action.

Objective: In this retrospective study, we assessed the efficacy of oral lactase in infants with lactose intolerance in terms of sex, birth weight, and interference by other medications. Methods: The study was conducted on patients aged 0–6 months who had been diagnosed with lactose intolerance on admission to the Department of Social Pediatrics at Dokuz Eylul University. Demographic data, the onset of symptoms, and medications used were recorded. Results: We found that 86.7% of the infants responded to lactase, with no significant differences based on sex, birth weight, or age at symptom presentation. We observed, however, that the efficacy of treatment did improve over time, thereby deriving benefits from intestinal development and adaptation. Interestingly, the response to lactase was reduced in infants receiving concomitant simethicone for colic symptoms, suggesting a potential drug interaction, while probiotics had no impact on treatment outcomes. Conclusions: We advise against using additional medications with oral lactase, pointing out a possible interaction with simethicone that might decrease the effectiveness of treatment.

Abstract Objective To investigate whether simethicone expediates the remission of abdominal distension after laparoscopic cholecystectomy (LC). Methods This retrospective study involved LC patients who either received perioperative simethicone treatment or not. Propensity score matching (PSM) was employed to minimize bias. The primary endpoint was the remission rate of abdominal distension within 24 h after LC. Univariable and multivariable logistic regression analyses were conducted to identify independent risk factors affecting the early remission of abdominal distension after LC. Subsequently, a prediction model was established and validated. Results A total of 1,286 patients were divided into simethicone (n = 811) and non-simethicone groups (n = 475) as 2:1 PSM. The patients receiving simethicone had better remission rates of abdominal distension at both 24 h and 48 h after LC (49.2% vs. 34.7%, 83.9% vs. 74.8%, respectively), along with shorter time to the first flatus (14.6 ± 11.1 h vs. 17.2 ± 9.1 h, P

Abstract Colonoscopy is the standard procedure for screening, and surveillance of colorectal cancer, including the treatment for colonic lesions. Colonic spasm is an important problem from colonoscopy that affects both surgeons and patients. The spasm also might be the cause of longer cecal intubation time, difficulty of the procedure, and increased pain. Previous reports indicated that antispasmodic agents can decrease such symptoms. Therefore, we conducted this study to investigate the cecal intubation time of antispasmodic agents. A single blinded randomized controlled trial was conducted from 01/11/2020 to 31/08/2021. One hundred four patients were allocated to antispasmodic agent group and control group, in 1:1 ratio. The efficacy of median (range) cecal intubation time showed similar results of 5 (2, 14) and 5 (2, 15) minutes with no statistically significant difference. The mean scores of all domains i.e., pain, spasm, cleanliness, and difficulty were better in the antispasmodic agent group about 2.6 (1.4), 1.8 (0.8), 2.4 (0.9), and 2.0 (0.9), respectively, than control group but there were spasm and cleanliness showed statistically significant difference. Moreover, the satisfaction scores showed better efficacy in decreased spasm, decreased difficulty, and increased cleanliness than control group. Prescribing of antispasmodic drugs before colonoscopy might be the choice of treatment for the patients. The antispasmodic drugs will be beneficial to both of the patient and the doctor.

Multiple logistic regression identified gallstone (OR = 0.33, P = 0.001), cholecystic polyp (OR = 0.53, P = 0.050), preoperative abdominal distention (OR = 0.63, P = 0.002) and simethicone use (OR = 1.89, P < 0.001) as independent factors contributing to the early remission of abdominal distension following LC. The prognosis model developed for predicting remission rates of abdominal distension within 24 h after LC yielded an area under the curve of 0.643 and internal validation a value of 0.644. Conclusions: Simethicone administration significantly enhanced the early remission of post-LC abdominal distension, particularly for patients who had gallstones, cholecystic polyp, prolonged anesthesia or preoperative abdominal distention.

Purpose: To assess the effect of simethicone, a defoaming agent, on improving visibility during drug-induced sleep endoscopy (DISE) in obstructive sleep apnea (OSA). Methods: The study was a retrospective case-series study on patients with OSA who failed positive airway pressure (PAP) treatment. Patient parameters were recorded including age, BMI, neck and abdominal circumference, and apnea–hypopnea index (AHI). Comparisons were made between DISE procedures performed with and without the administration of simethicone. Visibility during DISE was independently graded by two surgeons, and inter-rater reliability was assessed. Results: Simethicone significantly improved DISE visibility (p = 0.03). "Best visibility" was achieved in 55% of cases with simethicone compared to 27% without simethicone (p = 0.02). Sub-analysis showed that only simethicone administration had a significant effect on visibility (p = 0.02). Inter-rater reliability between the grading surgeons was strong (Cohen-Kappa score 0.7, p < 0.001). Conclusion: The findings suggest that simethicone enhances DISE visibility for OSA surgical planning. Further research should explore optimizing simethicone administration timing and the potential clinical implications for surgical outcomes and patient care. [ABSTRACT FROM AUTHOR]

Abstract The indications for liver stereotactic body radiation therapy (SBRT) continue to expand in the management of liver cancer due to the improved rates of local control with acceptable normal tissue toxicity. Changes in internal anatomy, such as the bowel, may negatively impact the precision of treatment delivery of SBRT liver treatment by influencing daily image matching. Institutions have developed various approaches to promoting bowel volume consistency. One such strategy is the administration of pharmaceuticals. The administration of pharmaceuticals, such as Simethicone, has been adopted by the Princess Alexandra Hospital Radiation Oncology Department (ROPAIR) as a method to promote consistency in the amount of bowel gas observed in liver cancer patients. This case series examines a group of patients treated at ROPAIR with liver SBRT to determine whether current practices effectively reduce the impact of bowel volume variations for liver cancer patients. Initial observations from this hypothesis generating research suggest potential improved consistency of the small bowel's anatomical position for liver SBRT patients who were administered Simethicone (Bowel bag dice similarity coefficient – Simethicone group = 0.79–0.92, Standard group = 0.24–0.93). However, it appeared that this strategy alone may not be entirely effective achieving consistency in the amount of bowel gas present throughout the duration of treatment. Further investigation into the refinement of liver SBRT pre‐treatment preparation is therefore recommended.

Background: Functional Abdominal Bloating and Distension (FABD) is a multifaceted condition related in part to trapped gas, with changes in the intestinal barrier and small intestinal bacterial overgrowth (SIBO), which lead to gas production. Currently, there are no treatments targeting the etiology of FABD. Methods: This double-blind, multicenter, randomized study evaluated the safety and efficacy of a product containing xyloglucan and pea proteins (XG + PP) compared with simethicone, both administered orally (three times daily) for 20 consecutive days. Eighty-eight patients with FABD were randomly assigned to the two groups in a 1:1 ratio. Primary outcome was safety; secondary outcomes were (i) efficacy in alleviating the symptoms of FABD and (ii) efficacy in reducing SIBO, as assessed by hydrogen breath test (HBT). Results: No Adverse Events or Serious Unexpected Adverse Reactions were reported during the study. XG + PP showed a faster onset of action and a significant reduction in bloating and abdominal pain compared with simethicone. At Day 20, XG + PP drastically reduced abdominal girth when compared with simethicone, with an average reduction of 4.7 cm versus 1.8 cm. At Day 20, the XG + PP arm showed a significant reduction in HBT compared to baseline. Conclusions: This study supports the evidence that FABD patients may benefit from a XG + PP-based treatment that acts on etiology and not just the symptoms. [ABSTRACT FROM AUTHOR]

Simethicone is an antiflatulent medication exclusively administered orally, thus its systemic effects remain unknown. We present a case of an inadvertent intravenous administration of simethicone to a 4-year-old patient, precipitating respiratory difficulty, cyanosis, and altered mental status. The patient’s condition improved rapidly with appropriate interventions, leading to discharge in a fully recovered state. To date, only one documented instance of intravenous simethicone administration exists in medical literature.

Introduction: Current guidelines suggest adding oral simethicone to bowel preparation for colonoscopy. However, its effect on key quality indicators for screening colonoscopy remains unclear. The primary aim was to assess the rate of adequate bowel preparation in split-dose high-volume polyethylene glycol (PEG), with or without simethicone. Methods: This is an endoscopist-blinded, randomized controlled trial, including patients scheduled for colonoscopy after a positive faecal immunochemical test. Patients were randomly assigned to 4 L of PEG split dose (PEG) or 4 L of PEG split dose plus 500 mg oral simethicone (PEG + simethicone). The Boston Bowel Preparation Scale (BBPS) score, the preparation quality regarding bubbles using the Colon Endoscopic Bubble Scale (CEBuS), ADR, CIR, and the intraprocedural use of simethicone were recorded. Results: We included 191 and 197 patients in the PEG + simethicone group and the PEG group, respectively. When comparing the PEG + simethicone group versus the PEG group, no significant differences in adequate bowel preparation rates (97% vs. 93%; p = 0.11) were found. However, the bubble scale score was significantly lower in the PEG + simethicone group (0 [0] versus 2 [5], p < 0.01), as well as intraprocedural use of simethicone (7% vs. 37%; p < 0.01). ADR (62% vs. 61%; p = 0.86) and CIR (98% vs. 96%, p = 0.14) did not differ between both groups. Conclusion: Adding oral simethicone to a split-bowel preparation resulted in a lower incidence of bubbles and a lower intraprocedural use of simethicone but no further improvement on the preparation quality or ADR.

Goals: To explore factors associated with inadequate gastric preparation for MCE. Background: Factors associated with inadequate gastric preparation for magnetically controlled capsule endoscopy (MCE) remains unclear. Study: Data of patients who underwent MCE from June 2021 to July 2022 were prospectively collected. The gastric cleanliness score (GCS) of the six stomach regions (gastric cardia, fundus, body, angulus, antrum, and pylorus) was recorded. Patients with GCS score ≥18 were defined as the adequate preparation. Factors related to inadequate gastric preparation were analyzed using a logistic regression model with estimated odds ratios (OR). Results: The mean GCS score of 211 patients was 17.01 ± 2.82. In the multivariable analysis, proton pump inhibitor (PPI) use (OR 3.57; 95% CI 1.69–7.95; p < 0.01) and premedication time after administering simethicone <30 min (OR 2.86; 95% CI 1.10–7.39; p = 0.03) were independent risk factors for inadequate gastric preparation. Comparing the gastric cleanliness of different locations, the median GCS of the lower stomach [10.00, IQR (9.50, 11.00)] was significantly higher than that of the upper stomach [7.00, IQR (6.00, 8.00)] (p <0.001). Conclusion: PPI use and inadequate premedication time (<30 min) may reduce the quality of gastric preparation for MCE. The type, dose, duration of medication, and discontinuation time of PPIs was well worth further exploration. Appropriate control of the type and time of premedication may be the key to improving overall gastric cleanliness. [ABSTRACT FROM AUTHOR]

Flexible endoscopes allow surgeons and proceduralists to view patients' internal organs through small incisions or natural orifices. These devices may be difficult to clean and dry adequately, and the formation of biofilm can further complicate effective cleaning. The updated AORN "Guideline for processing flexible endoscopes" provides perioperative personnel with evidence‐based best practice recommendations on a variety of concepts associated with this topic. This article provides an overview of the guideline and discusses recommendations for point‐of‐use treatment, transport, cleaning (including verification and drying), and storage of flexible endoscopes. It also includes a scenario that illustrates the importance of adequately drying and storing flexible endoscopes. When processing flexible endoscopes, personnel should adhere to the endoscope and processing equipment manufacturers' instructions for use. Perioperative nurses should review the guideline in its entirety and implement recommendations in practice settings where flexible endoscopes are used. [ABSTRACT FROM AUTHOR]

Continuous manufacturing is becoming the new technological standard in the pharmaceutical industry. In this work, a twin-screw processor was employed for the continuous production of liquisolid tablets containing either simethicone or a combination of simethicone with loperamide hydrochloride. Both active ingredients present major technological challenges, as simethicone is a liquid, oily substance, and loperamide hydrochloride was used in a very small amount (0.27% w/w). Despite these difficulties, the use of porous tribasic calcium phosphate as a carrier and the adjustment of the settings of the twin-screw processor enabled the optimization of the characteristics of the liquid-loaded powders and made it possible to efficiently produce liquisolid tablets with advantages in physical and functional properties. The application of chemical imaging by means of Raman spectroscopy allowed for the visualization of differences in the distribution of individual components of the formulations. This proved to be a very effective tool for identifying the optimum technology to produce a drug product. [ABSTRACT FROM AUTHOR]

Irritable Bowel Syndrome (IBS) is a common disease characterized by alternate symptoms (diarrhea and constipation) and intestinal gas overproduction. A new medical device (Fibergone®), containing Partially Hydrolyzed Guar Gum (PHGG) and Simethicone (SM) has been proposed for managing patients with bowel disorders. PHGG acts also as a prebiotic so increasing the Short-Chain Fatty Acid (SCFA) production, useful for intestinal physiology. This in vitro study investigated the effects exerted by PHGG+SM on SCFA production and their intestinal absorption following in vitro digestive process and fermentation model. An in vitro model evaluated the digestive process and fermentation using simulated digestive fluids and a human intestinal epithelium in vitro model derived from based on intestinal adenocarcinoma Caco-2 cells (ATCC, HTB-37TM) and organized as a functional monolayer on Transwell® inserts. PHGG+SM was added in experiments and compared with a control (non-treated). SCFA production and absorption were assessed. Viability and barrier integrity of the of the intestinal epithelium model were also evaluated. PHGG+SM significantly (p
