This study examined the growth of herb plants in response to irrigation on a green rooftop area in order to select herb plants that can be used for rooftop greening. Apple Mint (Mentha suaveolens), Lemon balm (Melissa officinalis), Spearmint (Mentha spicata), Pineapple sage (Salvia elegans), Choco Mint (Mentha × piperita 'Choco Mint'), Ox-eye Daisy (Chrysanthemum leucanthemum), Roman Chamomile (Anthemis nobilis) and Thyme (Thymus vulgaris) showed increased growth when irrigated. Conversely, Lavender (Lavendula angustifolia), Peppermint (Mentha × piperita), Vicks Plant (Plectranthus tomentosa), Feverfew (Tanacetum parthenium), Rosemary (Rosmarinus officinalis), Tansy (Tanacetum vulgare), Lemon Verbena (Aloysia triphylla), Heliotrope (Heliotropium arborescens), Soapwort (Saponaria officinalis) and Lady's mantle (Alchemilla vulgaris) demonstrated satisfactory growth regardless of irrigation. Peppermint, Tansy, Lemon Verbena, Soapwort, and Lady's mantle seem to be suitable for green rooftop because of their overwintering ability and drought hardiness. Pineapple sage, Apple Mint and Thyme would seem to be inappropriate for rooftop greening because they showed negative growth response to drought and failed overwintering. Although Spearmint, Lemon balm, Choco Mint, Ox-eye Daisy and Roman Chamomile had reduced growth during dry conditions, they were able to overwinter satisfactorily and can be used as rooftop plants with irrigation.
Purpose: The objective of this retrospective study is to evaluate the factors affecting the spread of odontogenic infection. Furthermore, this study was performed to apply to future treatments. Methods: A total of 65 patients, who had received treatment for odontogenic infections from 2010 to 2012 for 3 years, were enrolled in this study. The causes of infection, presence of systemic disease, and complications, durations of treatment, treatment methods, and inflammation levels were compared with the data. Results: Patients over 70 years with systemic disease required immediate drainage, systemic antibiotic therapy and hospitalization. We can determine the direction of the early diagnosis and treatment through blood tests (white blood cells, neutrophil, C-reactive protein [CRP]) and computed tomography. Patients over 70 years with systemic disease had the highest percentage. In addition, these patients showed high levels of inflammation index, such as CRP average of 24.8 and needed for a long-term treatment period and a wide range of surgical incision & drainage several times. Systemic diseases, particularly diabetes mellitus and hypertension, accelerate the spread of infection and had a negative effect that delays healing. Eventually, five of the 65 patients showed serious systemic complications. Conclusion: When evaluating cervico-facial infected patients due to odontogenic infection, the most important thing is deciding the appropriate diagnosis and degree of disease. Considering the patient's systemic status and age, we need to decide the treatment plan. Especially, those patients over 70 years with systemic disease should be treated with rapid surgical approach, and the use of a wide range of antibiotics and intensive care. If proper treatment principle does not apply, severe life-threatening complications will result, such as necrotizing fascitis, acute airway obstruction, mediastinitis, and others.
Multiple segment osteotomy orthognathic surgery serves to combine the total or segmental maxillary and mandibular correction of the dentofacial deformities with concurrent procedures to provide immediate repositioning to the dento-osseous elements. In addition, splitting the palate may often be necessary to correct a functionally poor relationship of the maxilla to the mandible or the facial skeleton by realigning the maxillary arch. In this case, the discrepancy in a bimaxillary horizontal relationship and the space between the 2nd premolar and 2nd molar was retained after lengthy preoperative orthodontic treatment. However, we could correct these dento-osseous discrepancies immediately by performing midpalatal expansion, anterior segmental osteotomy and symphyseal osteotomy with bimaxillary osteotomies. If the blood supply to each segment segments was maintained and primary closure of the operation site was feasible, multiple segment osteotomy was considered as a very effective technique for treating dentofacial deformities in vertical, transverse, and sagittal dimensions with differential repositioning of all segments.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
