    This project focused on formulation and investigation of interplay effects of ethosomes, ethanol and microwave for enhanced skin drug retention with minimal systemic absorption. The microwave was used to modify the skin barrier properties to enhance ethosomes and/or drug penetration/and drug retention which is detrimental to treat local malignant melanoma and to enhance patient compliance. Ethosomes are known to fuse with skin to enable local drug retention. Pre-treatment of skin with microwave and applying liquified medicine is deemed to “cement” the skin thereby raising skin drug deposition. 5-fluorouracil loaded ethosomes were prepared and subjected physicochemical characterization. The molecular characteristics of untreated, microwave and/or ethosomes and/or ethanol-treated skins were examined by ATR-FTIR and raman spectroscopy, DSC and SEM techniques. The skin drug retention was promoted using larger ethosomes with negative zeta potentials that repelled anionic lipids of skin and hindered vesicle and/or anionic drug penetration into deep layers. Due to low ethanol, they were less able to fluidize the lipid and defluidize the protein domains at epidermis to enlarge aqueous pores for drug permeation. Pre-treatment of skin by 2450 MHz microwave for 2.5 min further increased skin drug penetration and retention of E5 ethosomes and provided lower drug permeation than cases treated for 1.15 min and 5 min. Pre-treating skin with microwave fluidized lipid and defluidized protein domains of skin that promoted transdermal drug penetration

    ABSTRACT The benefits of using a laser in soft tissue treatment include less oedema, reduced inflammation, and quicker recovery. Nowadays, soft-tissue interventions, including periodontal recontouring, operculectomy, or frenectomy, are possible thanks to the introduction of diode lasers that are strongly absorbable melanin and haemoglobin. In this case, a 17-year-old patient at the near end of her orthodontic treatment was concerned about her gummy smile. She also had a gingival swelling in the lower anterior segment. Furthermore, she had a high labial frenum attachment. It was decided to go for a gingivectomy and frenectomy with the help of a laser (Diode Lasotronix 980nm).

    The recent research in Body Area Networks (BAN) is focused on making its communication more reliable, energy efficient, secure, and to better utilize system resources. In this paper we propose a novel BAN network architecture for indoor hospital environments, and a new mechanism of peer discovery with routing table construction that helps to reduce network traffic load, energy consumption, and improves BAN reliability. We have performed extensive simulations in the Castalia simulation environment to show that our proposed protocol has better performance in terms of reduced BAN traffic load, increased number of successful packets received by nodes, reduced number of packets forwarded by intermediate nodes, and overall lower energy consumption compared to other protocols

    OBJECTIVES: To assess the impact of sociodemographic factors with the trends of self-medication practice and its hazard perception among patients METHODOLOGY: A cross sectional descriptive study was conducted on the patients visiting Sharif Medical and Dental College from June 2019 to June 2020. Data was collected using a validated questionnaire from 142 patients. Chi-square and fisher exact tests were used to find the association of trends of self-medication practice and hazard perception with sociodemographic factors. RESULTS: The patients in the age range of 18 to 29 years practiced self-medication the most. The triggering factor for use of medication was toothache among all ages. The most commonly used drug was reported to be analgesics. The main reason for self-medication was lack of time to visit the doctor. The females practiced self-medication more than the males. The triggering factor for both the genders was toothache and analgesics were mostly used. The patients with tertiary level education and those who were unemployed practiced self- medication the most. The triggering factor was toothache across all levels of education and employed as well as unemployed patients. Drug resistance was stated the main hazard. CONCLUSION: The triggering factor for use of medication was toothache, most commonly used drugs were analgesics and the main reason for self-medication was lack of time across all ages, both the gender, married and unmarried patients, levels of education and employment. Un-employed patients and those with tertiary level of education-practiced self- medicated themselves the most. The highest percentage of patients considered drug resistance to be the biggest hazard

      To assess the knowledge and practices of dental practitioners regarding informed consent. METHODOLOGY: A descriptive cross-sectional study was conducted on 150 dentists at the College of Dentistry, Sharif Medical and Dental College, Lahore from June 2019 to June 2020. A pre-validated questionnaire was used. Mann Whitney U test was performed to find the statistical difference in the knowledge and practice scores across the gender and place of practice of dentists and the Kruskal Wallis test for scores across the years of clinical experience and qualification of dentists. RESULTS: The mean practice score was significantly different across levels of qualification (p=0.032) but not across years of practice (0.366). There was no significant difference in the mean knowledge score across years of practice (p=0.744) and levels of qualification (p=0.366). The highest mean score among knowledge questions was seen for the questions which inquired if informed consent should be taken before treatment. The highest mean score among practice questions was seen for the question which inquired if dentists obtained informed consent from parents before treating children.   CONCLUSION: The mean knowledge score for females was higher in comparison to males and was the highest in dentists with an experience of greater than 10 years. Most dentists were aware of the concepts, types and processes of informed consent and the importance of taking the patient`s consent before treatment. Taking informed consent from patients before treatment, keeping it as part of their record and taking parents’ consent before treating children were practiced

    Get PDF
    OBJECTIVES Lasers are used in almost every aspect of dentistry, be it surgeries, restorations, periodontal procedures, and even aesthetic dentistry. One certain area that requires extra emphasis and importance is the laser-assisted frenectomy. Frenectomy, as the name suggests, is the excision of frenum attachment to the underlying bone. Frenectomy is carried out in the mandible as well as the maxilla. This is a case of a patient undergoing orthodontic treatment who also required a frenectomy, and to minimize the postoperative pain and swelling, the procedure was carried out using a diode laser rather than the conventional surgical procedure
