Topical application of a sandal wood oil and turmeric based cream prevents radiodermatitis in head and neck cancer patients undergoing external beam radiotherapy: a pilot study.

OBJECTIVE: The study objective was to assess the effectiveness of a turmeric- and sandal wood oil-containing cream [Vicco(®) turmeric cream (VTC); Vicco Laboratories, Parel, India] on radiodermatitis in patients with head and neck cancer undergoing radiotherapy. METHODS: A total of 50 patients with head and neck cancer requiring >60 Gy of curative radiotherapy/chemoradiotherapy were enrolled in the study. The volunteers were randomly divided into two groups of 25 patients. Group 1 was assigned to a topical application of Johnson's(®) baby oil (Johnson & Johnson Ltd, Baddi, India) and Group 2 for VTC. Prophylactic application of the cream was initiated on Day 1 and continued every day until 2 weeks after the end of treatment. Both agents were symmetrically applied within the irradiated field five times a day, and the acute skin reactions were assessed twice weekly in accordance with the Radiation Therapy Oncology Group scores by an investigator who was unaware of the details. RESULTS: The incidence of radiodermatitis increased with the exposure to radiation and was the highest in both groups at Week 7. However, a significant reduction in grades of dermatitis were seen in cohorts applying VTC at all time points, including 2 weeks post radiotherapy (p < 0.015 to p < 0.001). The occurrence of Grade 3 dermatitis was lower in the cohorts using VTC and was statistically significant (p < 0.01). Additionally, follow-up observations 2 weeks after the completion of radiotherapy also showed a reduced degree of radiodermatitis in cohorts applying VTC, which was significant (p = 0.015). CONCLUSION: VTC is shown to be effective in preventing radiodermatitis and needs to be validated in larger double-blind trials. ADVANCES IN KNOWLEDGE: For the first time, this study shows that the turmeric- and sandal oil-based cream was effective in preventing radiation-induced dermatitis.

Statistical analysis was carried out to compare the antimicrobial effectiveness between materials tested with each of the bacterial groupings. CONCLUSION: Aloevera + Sterile Water was found to have superior antimicrobial activity against most of the microorganisms followed by ZOE + Aloevera, calcium hydroxide + Aloevera, ZOE, calcium hydroxide, Metapex in the descending order and Vaseline showed no inhibition.

Clinical guidelines and management of ankyloglossia with 1-year followup: report of 3 cases.

The tongue is an important oral structure that affects speech, position of teeth, periodontal tissue, nutrition, swallowing, nursing, and certain social activities. Ankyloglossia (tongue tie) is a congenital anomaly characterized by an abnormally short, thick lingual frenulum which affects movement of tongue. Though the effect of ankyloglossia in general appears to be a minor condition, but a major difference exists concerning the guidelines for tongue-tie division. There are no accepted practical criteria for the management of such condition, and hence this paper aims at bringing all the compilation in examination, diagnosis, treatment, and management of tongue tie together for better clinical approach.

Fibrolipoma of buccal mucosa.

The lipoma is a very common benign tumor of adipose tissue, but its presence in the oral and oropharyngeal region is relatively uncommon. Fibrolipoma, a histological variant of lipoma, mostly affect the buccal mucosa and causes functional and cosmetic disabilities. Hence, accurate histopathological examination of lipomas is important for a correct treatment plan. This article describes a case of 10 year old girl with fibrolipoma of the buccal mucosa with a relevant review of tumors.

Anticancer activity of Berberis aristata in Ehrlich ascites carcinoma-bearing mice: a preliminary study.

CONTEXT: Berberis aristata DC (Berberidaceae) is an important medicinal plant with claims of widespread medicinal value in indigenous medicine. It is used by herbal healers to treat oral cancers. OBJECTIVE: To evaluate the antineoplastic activity of the extracts of Berberis aristata in Ehrlich ascites carcinoma (EAC)-bearing mice with cisplatin as positive control in the advanced stage of tumorigenesis. MATERIALS AND METHODS: Brine shrimp lethality bioassay (BSL) of extracts and effect on the tumor cell viability in vitro were carried out. EAC was induced in Swiss albino mice by injecting 10(6) cell/mL of tumor cell suspension i.p. Antineoplastic activity of the aqueous and ethanol extracts (100 and 6.5 mg/kg i.p., respectively) was compared with that of cisplatin (3.5 mg/kg i.p.) on the parameters such as percentage increase in weight, median survival time, and hematology. RESULTS: Ethanol extract attenuated percentage increase in weight gain (-6.86 ± 1.50) due to tumor cell proliferation and increased the survival time (19.5 days) when compared to control group (19.10 ± 2.31 and 16 days, respectively). However, the effect was less than that of cisplatin. In vitro cytotoxicity assay as well as BSL test showed the cytotoxic effect of the extracts. Cisplatin and the extracts reversed the tumor-induced alterations in total white blood cell count, differential leukocyte counts, total red blood cell count, and hemoglobin contents. DISCUSSION AND CONCLUSION: Of the two extracts, the ethanol extract was observed to be more efficient and the presence of alkaloids and flavonoids may be responsible for the observed anticancer effects.

Zingiber officinale Roscoe (ginger) as an adjuvant in cancer treatment: a review.

Despite acquiring a strong understanding of the molecular basis and advances in treatment, cancer is the second major cause of death in the world. In clinics, the stagedependent treatment strategies may include surgery, radiotherapy and systemic treatments like hormonotherapy and chemotherapy, which are associated with side effects. The use of traditional herbal medicine in cancer patients is on a rise, as it is believed that these medications are non toxic and alleviate the symptoms of cancer, boost the immune system, or may tackle the cancer itself. Since antiquity the rhizome of Zingiber officinale Roscoe commonly known as ginger (family Zingiberaceae) have widely been used as a spice and condiment in different societies. Additionally, ginger also has a long history of medicinal use in various cultures for treating common colds, fever, to aid digestion, treat stomach upset, diarrhoea, nausea, rheumatic disorders, gastrointestinal complications and dizziness. Preclinical studies have also shown that ginger possesses chemopreventive and antineoplastic properties. It is also reported to be effective in ameliorating the side effects of γ-radiation and of doxorubicin and cisplatin; to inhibit the efflux of anticancer drugs by P-glycoprotein (P-gp) and to possess chemosensitizing effects in certain neoplastic cells in vitro and in vivo. The objective of this review is to address observations on the role of ginger as adjuvant to treatment modalities of cancer. Emphasis is also placed on the drawbacks and on future directions for research that will have a consequential effect on cancer treatment and cure.

Protective role of Trigonella foenum graceum extract against oxidative stress in hyperglycemic rats.

BACKGROUND AND OBJECTIVES: "In all things of nature there is something of the marvelous". In the present study the anti-hyperglycemic and anti-oxidative potential of aqueous extract of Trigonella foenum graceum (TFG), a traditional medicinal herb was assessed in liver and WBC of alloxan induced diabetic rats. Free radicals can cause oxidative damage, which is balanced by the antioxidants. This has been implicated in aging, and diseases such as diabetes and other chronic conditions. MATERIAL AND METHODS: TFG extract was administered orally [500 (LM) and 1000 mg/kg body weight (HM)] for six weeks. The effect of TFG on blood glucose were studied and the levels of lipid peroxidation [MDA (Malondialdehyde)] and antioxidant enzymes [SOD (Superoxide dismutase), GPx (Reduced Glutathione peroxidase)] were estimated and compared with standard drugs glibenclamide and insulin. RESULTS: Treatment with TFG, insulin and glibenclamide resulted in significantly reduced blood glucose in LM (8.71%) and HM (3.87%) in comparison with normal controls. There was a significant decrease in lipid peroxidation in liver and white blood cells (WBC) in both low and high doses [liver LM (49%), HM (57.25%)], [WBC LM (54.28%), HM (62.5%)] and increase in antioxidant enzymes SOD [liver LM (33.59%), HM (58.7%)] [WBC LM (44.9%)] HM (58.7%) and GPx [Liver LM (58.55%), HM (40.20%)], [WBC LM (55.46%), HM (56.4%)] when compared to diabetic controls. DISCUSSION: Potency of TFG in restoring several parameters to normal values is comparable to glibenclamide, though not as efficient as insulin, an indication of its antihyperglycemic and antioxidant effect.

Decreasing cariogenic bacteria with a natural, alternative prevention therapy utilizing phytochemistry (plant extracts).

The association between the oral microbiota and oral diseases is well established. Various antimicrobial agents including antibiotics are commercially available against oral pathogenic bacteria. For the reasons of antibiotic resistance, their adverse effects and financial considerations in the developing countries, there is a need for alternate preventive and curative treatment options that are also safe, effective and economical. Traditional medicines have been used since ancient times for the treatment of oral diseases including dental caries, periodontal diseases that affect the majority of the population and can affect a person's overall health. Natural phytochemicals are certain organic components isolated from plants and some of these extracts are considered to be beneficial to health. They serve as antioxidants, enhance immune response, provide protection against oral cancer and other diseases and also repair DNA damage caused by smoking and other toxic exposure, and detoxify carcinogens. The natural products derived from medicinal plants have proven to be an abundant source of biologically active compounds, many of which have been the basis for the development of new lead chemicals for pharmaceuticals. They are considered to be good alternatives to synthetic chemicals. This article presents a review of natural alternatives derived from plants and plant products that can serve as a prevention and treatment option against cariogenic bacteria.

Effect of topical honey on limitation of radiation-induced oral mucositis: an intervention study.

Radiation therapy for oral carcinoma is therapeutically useful in dose of at least 6000 cGy but causes mucositis that severely interferes with oral function. The literature indicates that honey appears to promote wound healing, so the authors investigated whether its anti-inflammatory properties might limit the severity of radiation-induced oral mucositis. A single-blinded, randomized, controlled clinical trial was carried out to compare the mucositis-limiting qualities of honey with lignocaine. A visual assessment scale permitted scoring of degrees of mucositis and statistical evaluation of the results was performed using the χ(2) test. Only 1 of 20 patients in the honey group developed intolerable oral mucositis compared with the lignocaine group, indicating that honey is strongly protective (RR=0.067) against the development of mucositis. The proportion of patients with intolerable oral mucositis was lower in the honey group and this was statistically significant (p=0.000). Honey applied topically to the oral mucosa of patients undergoing radiation therapy appears to provide a distinct benefit by limiting the severity of mucositis. Honey is readily available, affordable and well accepted by patients making it useful for improving the quality of life in irradiated patients.

Effect of fluorides from various restorative materials on remineralization of adjacent tooth: an in vitro study.

The aim of the study was to evaluate the extent of surface zone remineralization and the effect of fluoride at the inter-proximal adjacent tooth surface, using restorative materials FusionAlloy, Ketac-Fil and Heliomolar. Ninety extracted molar teeth were used of which 45 were placed in artificial caries for 10 weeks. The remaining 45 teeth were filled with the respective restorative materials, mounted with the artificial carious teeth in proximal contact with plaster and placed in artificial saliva for a period of 28 days. Finally, sectioning of artificially carious teeth was done mesio-distally and observed under the optical microscope and scanning electron microscope. Comparison among the groups was done by one-way analysis of variance [ANOVA] and Fischer's F test. Intercomparison between the groups was done by using Dunnett's t-test. Results obtained from transmitted electron microscopic and scanning electron microscopic observations were almost similar with the Ketac-Fil and Heliomolar showing better results in surface zone remineralization compared to FusionAlloy. Also, Ketac-Fil is a good material in releasing fluoride to remineralize enamel when compared to Heliomolar and FusionAlloy. Thus, it can be used mainly in class II cavity restorations of primary and permanent dentitions due to the potential ability of fluoride containing glass ionomer cements and composite resins to remineralize incipient carious lesions on adjacent teeth.

Assessing patient readiness for the clinical adoption of personalized medicine.

BACKGROUND/AIMS: Although pharmacogenomics-based diagnostics and therapeutics are increasingly being translated into personalized medicine applications, relatively little evidence exists about how novel pharmacogenomics-based technologies will be accepted and adopted by patients. It is important to understand the characteristics of genomic diagnostics and targeted therapeutics that might impact utilization or serve as barriers to adoption of these novel technologies in order to formulate appropriate policies and procedures. The objective of this study was to investigate patients' understanding and knowledge of personalized medicine and the process of decision-making regarding pharmacogenomics testing and targeted therapeutics and to better understand how patients value receiving pharmacogenomics-based care. METHODS: We conducted 4 focus groups with 8-10 individuals in each group with patients recruited from out-patient clinics at The Methodist Hospital in Houston, Tex., USA. RESULTS: The use of genomic diagnostics and targeted therapeutics to facilitate personalized medicine has considerable support from patients. However, our data revealed that participants were concerned with issues surrounding privacy and confidentiality of genetic test results, particularly with respect to access of information by insurers, with potential costs of testing and issues related to accuracy of test results. Questions regarding willingness to pay revealed that patients would be more willing to pay out-of-pocket if the disease associated with pharmacogenomic testing for treatment was perceived to be high risk (e.g., colorectal cancer) versus a chronic condition that was perceived as lower risk (e.g., high cholesterol). CONCLUSION: As the personalized medicine approach is increasingly incorporated into health care, understanding patients' needs and their readiness to adopt these novel technologies will become progressively more important for the development of appropriate health policies.

Crouzons syndrome: a case report.

Human skull is made up of many bone joints connected by sutures. The sutures fuse in later life after the complete growth of the brain. If any of these sutures closes early, it may interfere with the normal growth of the brain. The developing brain may exert pressure on the skull and may grow in the direction of the other open sutures. Premature sutural fusion may occur alone or together with other anomalies, making up various syndromes. Crouzons syndrome is an example of such a syndrome that is associated with premature synostosis of the sutures of the skull. Presented in this article is a case of Crouzons syndrome seen in a boy aged 9 years.

Crossed hemifacial hyperplasia: a diagnostic dilemma.

Crossed hemifacial hyperplasia is a rare condition producing facial asymmetry and overgrowth of the extremities of the opposite side. Very few cases are reported in literature. A case of an 11-year-old female is presented here to supplement existing clinical knowledge with many of the reported clinical and orofacial findings. Emphasis is placed on diagnosis of the condition by thoughtful elimination and the necessity of a multi-disciplinary approach to its management.

Is povidone-iodine a hemostyptic? A clinical study.

Povidone-iodine (PVP-I) is an antiseptic agent commonly used on intact skin in preparation for surgery and on open wounds. In oral surgery it is used for irrigating alveolar sockets following extraction. The present authors found by chance that irrigation of extraction sockets with povidone-iodine led to cessation of bleeding in patients without recurrence. Fifty patients were selected and divided equally into treatment and control groups. Povidone-iodine (1%, w/v) was used for irrigation of extraction sockets in the treatment group and saline was used in the control group. In the treatment group, 19 patients showed cessation of bleeding compared to only 5 in the control group. Povidone-iodine significantly (P<0.01) controlled bleeding as compared to saline. Iodine is corrosive due to its oxidizing potential while povidone is a thickening and granulating agent; together they may have a chemocauterizing effect that could be the reason for the cessation of bleeding. These results suggest that povidone-iodine may act as a hemostyptic as well as an antiseptic.
