Odor Masking, Stability and Sensoriality: Researching Background agents in Complex Systems for Infinite Solutions

Consumers are increasingly aware and threatened by skin-related concerns. They face an increasingly hectic lifestyle and harsh environmental conditions, so they pay more attention to their state of health and increase their level of awareness. The available literature is full of examples using cosmeceuticals and pharmaceuticals that demonstrate multiple beneficial activities. However, this trend creates obstacles in the formulation due to the need to manage the organoleptic properties of the finished products, for example the emission of "unpleasant" odours. The emission of unpleasant odours inevitably tends to directly or indirectly compromise the entire formulation and its "sensory pleasantness". In fact, it is of fundamental importance to take into account that cosmetics, unlike drugs, are not intended to cure, but are characterized by a complex interaction between psyche, skin and product. The analysis of the social context and the context of use of the product is growing strongly to ensure the growth of this sector. Cosmetic products are designed to offer pleasant sensory experiences and meet different human needs. In cosmetics the sensory experience is given through the cosmetic "vehicle" transmitting a unique sensation to the skin thanks to its ingredients

Differentiation of Inflammatory from Fibrotic Ileal Strictures Among Patients with Crohn’s Disease through Analysis of Time-intensity Curves Obtained after Microbubble Contrast Agent Injection

The aim was to assess whether the analysis of time-intensity curves obtained after microbubble contrast agent injection could differentiate inflammatory from fibrotic ileal strictures among patients with Crohn\u2019s disease (CD). Sixty-five consecutive patients (40 male and 25 female; mean age \ub1 SD, 42.2 years \ub1 12.22) with stricture of the terminal ileal loop from CD were scanned after microbubble injection. Time-intensity curves were obtained from quantitative analysis and peak enhancement, rise time, time to peak, area under the time-intensity curve (AUC), AUC during wash-in (AUCWI), and AUC during wash-out (AUCWO) were compared between patients with inflammatory vs patients with fibrotic strictures. Inflammatory (n=40) vs fibrotic strictures (n=25) differed (P<.05) in the peak enhancement, the wash-in rate, the wash-in perfusion index, AUC, AUCWI, AUCWO. The quantitative analysis of small bowel wall contrast enhancement after microbubble contrast agent injection may differentiate inflammatory from fibrotic ileal strictures in patients with CD

Time-intensity curves obtained after microbubble injection can be used to differentiate responders from nonresponders among patients with clinically active Crohn disease after 6 weeks of pharmacologic treatment

Purpose: To assess whether contrast material-enhanced ultrasonography (US) can be used to differentiate responders from nonresponders among patients with clinically active Crohn disease after\ub1weeks of pharmacologic treatment. Materials and Methods: This prospective study was approved by our ethics committee, and written informed consent was obtained from all patients. Fifty consecutive patients (26 men and 24 women; mean age, 34.76 years\ub19) with a proved diagnosis of active Crohn disease who were scheduled to begin therapy with biologics (infliximab or adalimumab) were included, with enrollment from June 1, 2013, to June 1, 2015. In each patient, the terminal ileal loop was imaged with contrast-enhanced US before the beginning and at the end of week\ub1of pharmacologic treatment. Time-intensity curves obtained in responders (those with a decrease in the Crohn disease endoscopic index of severity score of 25-44 before treatment to 10-15 after treatment, an inflammatory score ,7, and/or a decrease 6570 in the Crohn disease activity index score compared with baseline) and nonresponders were compared with Mann-Whitney test. Results: Responders (n = 31) and nonresponders (n = 19) differed (P , .05) in the percent change of peak enhancement (240.78\ub162.85 vs 53.21\ub172.5; P = .0001), wash-in (234.8\ub167.72 vs 89.44\ub1145.32; P = .001) and washout (25.64\ub1130.71 vs 166.83\ub1204.44; P = .002) rate, wash-in perfusion index (242.29\ub159.21 vs 50.96\ub171.13; P = .001), area under the time-intensity curve (AUC; 246.17\ub148.42 vs 41.78\ub187.64; P = .001), AUC during wash-in (243.93\ub154.29 vs 39.79\ub170.85; P = .001), and AUC during washout (249.36\ub147.42 vs 42.65\ub197.09; P = .001). Responders and nonresponders did not differ in the percent change of rise time (5.09\ub149.13 vs 6.24\ub148.06; P = .93) and time to peak enhancement (8.82\ub154.5 vs 10.21\ub143.25; P = .3). Conclusion: Analysis of time-intensity curves obtained after injection of microbubble contrast material\ub1weeks after beginning pharmacologic treatment can be used to differentiate responders from nonresponders among patients with clinically active Crohn disease

Laser interstitial thermal therapy in pediatric cerebellar epilepsy

Cerebellar lesional epilepsy is rare, commonly manifesting in early life and posing diagnostic and treatment challenges. Seizure semiology may be subtle, with repetitive eye blinking, face twitching, and irregular breathing, while EEG commonly remains unremarkable. Pharmacoresistance is the rule, and surgical intervention is the only treatment with the potential for cure. Novel minimally invasive techniques, such as laser interstitial thermal therapy (LITT), are emerging for surgically less accessible, deep-seated epileptogenic lesions. We report the case of a patient who presented with peculiar eye and face movements occurring episodically and stereotypically since the first weeks of life and was later diagnosed with cerebellar epilepsy related to a hamartoma. Refractory daily seizures, unresponsive to antiseizure medication, were followed by increasingly prominent gait ataxia and delayed speech development. Staged LITT was performed in two consecutive sessions at 3 and 4 years, leading to seizure cessation, neurological improvement, and developmental gains over a postsurgical follow-up period of 8 months. Our case highlights cerebellar lesional epilepsy as a rare but important differential diagnosis in children with paroxysmal disorders predominantly involving the face. Furthermore, we illustrate the radiological correlates of neurocognitive deficit related to the cerebellar lesion, manifesting as cerebello-cerebral diaschisis. Most importantly, our observations showcase LITT as a safe and effective therapeutic approach in cerebellar lesional epilepsy and an attractive alternative to open brain surgery, especially for deep-seated lesions in the pediatric population

Lesion Extent Negatively Impacts Intellectual Skills in Pediatric Focal Epilepsy

BACKGROUND Cognitive development in children and adolescents with focal lesional epilepsy is determined by the underlying epileptogenic lesion, in addition to epilepsy itself. However, the impact of lesion-related variables on intelligence quotient (IQ) and developmental quotient (DQ) remains largely unexplored. Here, we aimed to determine the effect of lesion-related predictors and their relation with epilepsy-related predictors of intellectual functioning. METHODS We retrospectively analyzed data from children with focal lesional epilepsy who underwent standardized cognitive evaluation yielding IQ/DQ in our institution. RESULTS We included 50 consecutive patients aged 0.5 to 17.5 years (mean, 9.3; S.D., 4.9) at cognitive assessment. Epilepsy duration was 0 to 15.5 years (mean, 3.8; S.D., 4.1). Of the total cohort, 30 (60%) patients had unilobar lesions, seven (14%) multilobar, 10 (20%) hemispheric, and three (6%) bilateral. Etiology was congenital in 32 (64%) cases, acquired in 14 (28%), and progressive in four (8%). For patients with unilobar lesions, the mean IQ/DQ was 97.1 ± 15.7, for multilobar 98.9 ± 20.2, for hemispheric 76.1 ± 20.5, and for bilateral 76.3 ± 4.5. Larger lesion extent, earlier epilepsy onset, and longer epilepsy duration correlated with lower IQ/DQ in the univariate analysis, whereas only lesion extent and epilepsy duration contributed significantly to the explanatory model in the multivariable analysis. CONCLUSIONS The present study demonstrates that lesion extent and epilepsy duration are important risk factors for intellectual impairment in pediatric patients with focal lesional epilepsy. These findings are useful for family counseling and the early consideration of interventions that may limit the duration of epilepsy

Out of Place: Gallstone Ileus

PRESENTATION Infrequently, a gallstone can travel into the small intestine and lodge there, causing bowel blockage. This was the case for a 70-year-old man who was referred to us with abdominal pain, persistent nausea, and vomiting. He also reported dyspepsia of 3 months\u2019 duration. His medical history included hypertension, chronic ischemic heart disease, and type 2 diabetes mellitu

Colorectal Cancer Stage at Diagnosis Before vs During the COVID-19 Pandemic in Italy

IMPORTANCE Delays in screening programs and the reluctance of patients to seek medical attention because of the outbreak of SARS-CoV-2 could be associated with the risk of more advanced colorectal cancers at diagnosis. OBJECTIVE To evaluate whether the SARS-CoV-2 pandemic was associated with more advanced oncologic stage and change in clinical presentation for patients with colorectal cancer. DESIGN, SETTING, AND PARTICIPANTS This retrospective, multicenter cohort study included all 17 938 adult patients who underwent surgery for colorectal cancer from March 1, 2020, to December 31, 2021 (pandemic period), and from January 1, 2018, to February 29, 2020 (prepandemic period), in 81 participating centers in Italy, including tertiary centers and community hospitals. Follow-up was 30 days from surgery. EXPOSURES Any type of surgical procedure for colorectal cancer, including explorative surgery, palliative procedures, and atypical or segmental resections. MAIN OUTCOMES AND MEASURES The primary outcome was advanced stage of colorectal cancer at diagnosis. Secondary outcomes were distant metastasis, T4 stage, aggressive biology (defined as cancer with at least 1 of the following characteristics: signet ring cells, mucinous tumor, budding, lymphovascular invasion, perineural invasion, and lymphangitis), stenotic lesion, emergency surgery, and palliative surgery. The independent association between the pandemic period and the outcomes was assessed using multivariate random-effects logistic regression, with hospital as the cluster variable. RESULTS A total of 17 938 patients (10 007 men [55.8%]; mean [SD] age, 70.6 [12.2] years) underwent surgery for colorectal cancer: 7796 (43.5%) during the pandemic period and 10 142 (56.5%) during the prepandemic period. Logistic regression indicated that the pandemic period was significantly associated with an increased rate of advanced-stage colorectal cancer (odds ratio [OR], 1.07; 95%CI, 1.01-1.13; P = .03), aggressive biology (OR, 1.32; 95%CI, 1.15-1.53; P &lt; .001), and stenotic lesions (OR, 1.15; 95%CI, 1.01-1.31; P = .03). CONCLUSIONS AND RELEVANCE This cohort study suggests a significant association between the SARS-CoV-2 pandemic and the risk of a more advanced oncologic stage at diagnosis among patients undergoing surgery for colorectal cancer and might indicate a potential reduction of survival for these patients

The most appropriate time delay after microbubble contrast agent intravenous injection to maximize liver metastasis conspicuity on contrast-enhanced ultrasound

Purpose: To identify the most appropriate time delay after microbubble contrast agent injection to maximize liver metastasis conspicuity on contrast-enhanced ultrasound (CEUS). Methods: Twenty-five consecutive patients (12 male and 13 female; age: 50 ± 13 years) with a known primary tumor and evidence of liver metastases on unenhanced ultrasound (US) underwent CEUS. CEUS consisted of continuous liver parenchyma scanning during arterial (15–35 s after microbubble injection), portal venous (40–120 s), and late phase (from 120 s up to microbubble disappearance). Subjective conspicuity index (ranging from 1 to 5) and objective conspicuity index (Ilesion–Iliver/Iliver, I = signal intensity) were calculated on reference frames selected on arterial phase and every 20 s on portal venous and late phase. Results: A total number of 40 liver metastases were identified after microbubble injection. The highest liver metastasis conspicuity was observed on early portal venous phase (40–60 s after microbubble injection) both on visual (mean subjective conspicuity index ± standard deviation [SD] = 4.36 ± 0.75, reader 1; 4.25 ± 0.65, reader 2) and quantitative analysis (mean objective conspicuity index ± SD = −0.99 ± 0.001). Conclusion: The early portal venous phase (40–60 s after microbubble injection) provides the best liver metastases' conspicuity after microbubble contrast agent injection
