ABSTRACT
Context: Carbon monoxide (CO) concentrations in exhaled air may impart a quick, non-invasive method to determine smoking status. Haras is a nutraceutical medication, which is slowly gaining recognition for its antioxidant and anti-inflammatory activities. Aims: The effectiveness of the Haras therapy in smokers and non-smokers will be assessed by evaluating breath CO levels. Methods and Materials: The study included 101 test subjects with 76 subjects of smokers and 25 subjects of non-smokers. Both the test groups were given 10 mL of Haras juice in divided doses per day for 30 days. The CO levels were evaluated using a breath analyser before drug trial and then on the 8th, 15th, 22nd and after the conclusion of the drug trial. Statistical Analysis Used: The Wilcoxon signed-rank test was used to compare the CO and carboxyhemoglobin levels among smokers and non-smokers. Results: Smokers had higher mean percent carboxyhemoglobin and mean parts per million CO values than non-smokers, and the difference between the two was shown to be statistically significant (P < 0.001). It was also found to be statistically significant from the first day to the eighth day, the first day to the 15th day, the first day to the 20th second day, first day to the 30th day (P < 0.001). Conclusions: Haras can be used effectively as an alternative supportive treatment for the diminution of CO levels in smokers and non-smokers.
ABSTRACT
Ewing's sarcoma (ES) is a small blue round cell tumor, malignant in nature typically affecting long bones and pelvis. Occurrence of ES in the head and neck region is rare and is reported to be 2%-3%, of which the chances of having primary lesion are rare. In the head and neck region, it has been reported to strike skull, supraclavicular region, parotid region, orbital floor, nasal cavity, maxilla, mandible and zygoma. We present a case of primary ES of the mandible in a 22-year-old female who reported with a palpable swelling on the lower left part of the face; and intraorally, there was a growth in the molar region. Orthopantomogram showed multilocular radiolucency in the molar-ramus region. The diagnosis was made after surgical resection, histopathology and immunohistochemistry profiling. The patient was treated by cortical segmental resection of mandible combined with chemotherapy and a follow-up was done for 2 years.
ABSTRACT
CONTEXT: Odontogenic cysts are among the most common lesions to affect the oral and maxillofacial region. Cysts are capable of causing significant bony disfigurement, tooth displacement and pathological fractures. Several surgical approaches exist for the management of larger cysts of the jaws. These include enucleation, marsupialization and decompression. AIMS: 1. Analysis of histopathologic findings in odontogenic cysts before and after decompression2. Analysis of Ki-67 expression in odontogenic jaw cysts before and after decompression. SETTINGS AND DESIGN: Decompression technique was used for the treatment of 10 cases of odontogenic cysts in the study. Incisional biopsies of cystic lining (pretreatment) and corresponding excisional biopsies (posttreatment) were received for histopathologic and immunohistochemical examination. SUBJECTS AND METHODS: Hematoxylin and eosin stain was used for histopathologic findings, and Ki-67 was used for immunohistochemical findings using antibody Ki-67 in fresh tissue samples. RESULTS: Overall, radicular cysts, dentigerous cysts, and sialo-odontogenic cyst contained fewer Ki-67 + cells than odontogenic keratocysts. The average scores were found to be 2.2 and 1 for before and after decompression, respectively. A statistically significant difference was observed between the two groups. The two-tailed P value was found to be <0.0001. The confidence interval was found to be 95%. CONCLUSIONS: The proliferative activity evaluated by Ki-67 marker was greater in predecompression epithelial lining compared to postdecompression. Our study infers that proliferative rate of the cystic epithelial lining is significantly diminished after decompression.
