The Role of Natural Extracts in the Management of Infantile Hemangiomas and Vascular Tumors

Hemangiomas are vascular tumors resulting from the proliferation of endothelial-like cells; they are the most common childhood tumors, affecting approximately 5-10% of newborns and infants. Besides hemangiomas, which are definitely benign tumors despite their overgrowth potential, there are other vascular tumors like hemangioendotheliomas, which may display intermediate characteristics between benign hemangiomas and highly malignant angiosarcomas. Standard therapy may be constricted by serious adverse effects, high cost, or traumatic influence. Diet is a major resource for health preservation, disease prevention, and treatment. The therapeutic property of edible berries, marine products, or medicinal plants have long been known and used in traditional medicine; a plant-based nutrition can prevent the development and progression of diseases associated with extensive neo-vascularization. The purpose of our review is to highlight those natural treatments that hemangioma and vascular tumor patients can receive in the future, both for their benefit and that of their families. We performed the review according to the Preferred Reporting Items for Systematic Reviews and Metanalysis Statement. We used the Web of Science, PubMed, and EMBASE engines for the study, and searched for the association of hemangioma with naturopathic treatment/plant extract/plants in published articles. We found that natural extracts from plants and fruits are cost-effective and safe treatments for hemangiomas and vascular tumors, as well as for other forms of cancer. In any case, more in vitro and in vivo studies are needed to confirm the proposed signaling pathways in tumors and validate the improvement parameters after natural products administration. The era of molecularly targeted therapy and personalized medicine is approaching and naturally occurring substances are very useful tools for tumor treatment and prevention. Plant extract substances have strong specificity and pertinence, are non- toxic and have few side effects, and may become an emerging cancer treatment.

Catching Cancer Early: The Importance of Dermato-Oncology Screening

The European Society for Medical Oncology experts have identified the main components of the long-term management of oncological patients. These include early diagnosis through population screening and periodic control of already diagnosed patients to identify relapses, recurrences, and other associated neoplasms. There are no generally accepted international guidelines for the long-term monitoring of patients with skin neoplasms (nonmelanoma skin cancer, malignant melanoma, precancerous-high-risk skin lesions). Still, depending on the experience of the attending physician and based on the data from the literature, one can establish monitoring intervals to supervise these high-risk population groups, educate the patient and monitor the general population.

Cross-Sectional Study to Evaluate Knowledge on Hand Hygiene in a Pandemic Context with SARS-CoV-2

Background and Objectives: The basis of any infection control program is hand hygiene (HH). The aim of this study was to investigate knowledge of HH among medical students. Materials and Methods: Students were randomly selected from two Romanian universities and a cross-sectional, questionnaire-based study was conducted between January and May 2021. The answers regarding demographic data and knowledge concerning the methods, the time and the antiseptics used for HH were collected. The selection of the study group was made according to selection criteria in accordance with ethical issues. A descriptive statistical analysis was performed, and a chi-square test was used for data comparison, with a cut-off point of 0.05 for statistical significance. Results: The results indicated that the attitude of the students towards the practice of HH improved significantly. Most students believe that simple HH can control infections. Significant differences were found by the year of study in terms of the hand surfaces included and recommended duration (p < 0.05). Conclusions: In conclusion, the study shows that most respondents have sufficient knowledge on HH, meaning that a higher compliance is required to control infections. The indicated reasons of non-compliance with HH are emergencies and other priorities.

[SEM comparative analysis of the composite diacrylic resin-enamel interface in laser and bur prepared cavities]

The aim of this study was to demonstrate that the size of the hybrid layer (HL) in the prepared enamel mechanic (M) and kinetic (K) with laser (WaterlaseMDBiolase), evaluated by scanning electron microscopy (SEM) restored with two types of resin composite is different.

MATERIAL AND METHOD

The study was realized in vitro on a sample of 40 extracted human premolar and molars teeth for orthodontic or periodontal reasons. The teeth were divided at random into equal four groups (Gr). There has been Class I cavities with a depth of 2 mm (M) at high and low speed with cylindrical diamond No.1 and globular carbide and (K) peaks MZ6-5, 5W+20 Hz 30% water 60% air. The teeth were restored using 3M Schotchbond Etch, 3M Single Bond Dental Adhesive System: Gr. 1: (K)(n = 10)-3M Filtekflow; Gr.2 : (K)(n = 10)3M FiltekZ250; Gr.3: (M)(n = 10)3M Filtekflow; Gr.4: (M)(n = 10)3M FiltekZ250. The materials were placed in a single layer and photoactivate source LED SmartLite (Dentsply), termocycling 500 cycles (5 degrees-55 degrees), stored (48h), cut lengthwise (diamond), polished, conditioned (H3PO4-37% -5s) analyzed by SEM (JEOLJSM 6390), SPSS 13.00 statistically analyzed (ANOVA, p = 0.05).

RESULTS

Analysis of the (HL) has highlighted differences between groups p = 0.05 average size (HL) being Gr.1;20.80 (+/- 0.72)microm, Gr.2;4.034 (+/- 0.0076)microm, Gr.3, 14.13 (+/- 0.63)microm, Gr.4, 1,43 (+/- 0.16)microm. Value size (HL) was influenced by the cavity preparation method for samples prepared by laser p = 0,005 in terms of size and in advantage of mechanical preparations in terms of quality (HL). Also the value of (HL) size was influenced by the type of material used in advance Gr.2 p = 0.0017.

CONCLUSIONS

The sealing of cavity depends more on the creep of materials and less on the type of preparation. Permission was obtained from a institutional ethical committee of "Gr.T. Popa" University of Medicine and Pharmacy Iaşi and that subjects gave written, informed consent).

[Comparative study on the periodontal health status trough plaque and gingival index]

Nowadays, people are becoming more aware of the importance of oral hygiene in maintaining the health of the entire body. It is well known that plaque is the main etiological factor in producing caries disease and periodontal disease. The purpose of this study was to evaluate the comparative value indices of plaque and gingival inflammation in a group of young adults.

MATERIAL AND METHOD

The study was conducted on a sample of 254 subjects. The study was clinical type. Data were collected after completion revelation plaque and clinical examination recorded the values calculated for each index in the observation sheet. The clinical evaluation of oral health status we used the API index (approximated Plaque Index) and BI indices for assessing periodontal status (bleeding index). All subjects included in the study were informed verbally about the purpose of the study noting the consent form. Patients were included in the database according to certain codes. Statistical data processing was done with the program for Windows SPSS14.00 setting a threshold of statistical significance of p = 0.05.

RESULTS

Comparative analysis of the presence of plaque and degree of gingival inflammation has revealed that there are differences statistically significant p < or = 0.05 for having a valoatre API index averaged 72.71 (+/- 23.48) compared with gingival index = BI has an average of 20.05 (+/- 18.32) and that influences the use of dental wire index periodontal inflammation.

CONCLUSIONS

Gingival inflammation is present in those with plaque and is subject to use wire but not the frequency of tooth brushing which demonstrates that the use of adjuvant means brushing helps remove plaque but not entirely.
