Abstract Aim Maxillectomy often results in a high level of morbidity with significant psychological and functional implications for the patient. Such disabilities include inability to masticate, deglutition, and speech disturbance. Unfortunately, little is known about the nature of the speech disturbance and the influence of the class of surgical defects in this group of patients. The aims of the present study were to assess the effectiveness of the maxillary obturator as a speech rehabilitation aid and to examine the influence of the classes of surgical defects on speech intelligibility (SI). Materials and Methods Twelve patients aged between 18 and 60 years with surgically acquired partial maxillary defects were included in this study. The patients were given immediate surgical obturators six to ten days after surgery, which were then converted to interim obturators by relining with tissue conditioner. Interim prostheses were used for two to three months until healing and resorption were found satisfactory after which the definitive obturators were fabricated. The SI test described by Plank et al.1 and Wheeler et al.8 was employed in this study. There were significant improvements in the mean SI score from 59.8% without prosthetic obturation, to 89.2% following interim obturation, and 94.7% following definitive obturation (p<0.005). Nine patients (75%) had class I surgical defects, two patients (16.67%) had class II defects, while only one patient (8.33%) had a class VI surgical defect. None of the patients had class III, IV, or class V surgical defects. There was an improvement in the SI score from class I to class VI without obturation, after insertion of interim obturator, and after insertion of the definitive obturator. Conclusion Results support the widely held view that the maxillary obturator is a useful speech rehabilitation aid. It also shows immediate, interim, and definitive obturators are all important in the speech rehabilitation of patients with surgically acquired maxillary defects. Moreover SI is affected by the class of defect. Citation Arigbede AO, Dosumu OO, Shaba OP, Esan TA.

Background. Previous studies have shown that environmental cadmium exposure could disrupt salivary gland function and is associated with dental caries and reduced bone density. Therefore, this cross-sectional study attempted to determine whether tooth decay with tooth loss following cadmium exposure is associated with some dental or skeletal traits such as malocclusions, sagittal skeletal pattern, and tooth decay. Methods. Between August 2019 and June 2020, 60 orthodontic patients with no history of previous orthodontics, functional appliances, or surgical treatment were examined. The patients were stratified into two groups according to their urine cadmium concentrations: high (>1.06 µg/g creatinine, n = 28) or low (<1.06 µg/g creatinine, n = 32). Results. The patients were 25.07 ± 4.33 years old, and most were female (female/male: 51/9 or 85%). The skeletal relationship was mainly Class I (48.3%), followed by Class II (35.0%) and Class III (16.7%). Class I molar relationships were found in 46.7% of these patients, Class II molar relationships were found in 15%, and Class III molar relationships were found in 38.3%. The mean decayed, missing, and filled surface (DMFS) score was 8.05 ± 5.54, including 2.03 ± 3.11 for the decayed index, 0.58 ± 1.17 for the missing index, and 5.52 ± 3.92 for the filled index. The mean index of complexity outcome and need (ICON) score was 53.35 ± 9.01. The facial patterns of these patients were within the average low margin (26.65 ± 5.53 for Frankfort–mandibular plane angle (FMA)). There were no significant differences in the above-mentioned dental indices between patients with high urine cadmium concentrations and those with low urine cadmium concentrations. Patients were further stratified into low (<27, n = 34), average (27–34, n = 23), and high (>34, n = 3) FMA groups. There were no statistically significant differences in the urine cadmium concentration among the three groups. Nevertheless, a marginally significant p-value of 0.05 for urine cadmium concentration was noted between patients with low FMA and patients with high FMA. Conclusion. This analysis found no association between environmental cadmium exposure and dental indices in our orthodontic patients.

ABSTRACT The type IV pili of plasmid R64 belonging to the type IVB group are required only for liquid mating. They consist of the major and minor components PilS pilin and PilV adhesin, respectively. PilS pilin is first synthesized as a 22-kDa prepilin from the pilS gene and is then processed to a 19-kDa mature pilin by PilU prepilin peptidase. In a previous genetic analysis, we identified four classes of the pilS mutants (T. Horiuchi and T. Komano, J. Bacteriol. 180:4613-4620, 1998). The products of the class I pilS mutants were not processed by prepilin peptidase; the products of the class II mutants were not secreted; in the class III mutants type IV pili with reduced activities in liquid mating were produced; and in the class IV mutants type IV pili with normal activities were produced. Here, we describe a novel class, class V, of pilS mutants. Mutations in the pilS gene at Gly-56 or Tyr-57 produced type IV pili lacking PilV adhesin, which were inactive in liquid mating. Residues 56 and 57 of PilS pilin are suggested to function as an interface of PilS-PilV interactions.

ABSTRACT Introduction: Pubertal growth peak is closely associated with a rapid increase in mandibular length and offers a wide range of therapeutic modifiability. Objective: The aim of the present study was to determine and compare the mean ages of onset and duration of pubertal growth peak among three skeletal classes. Methods: A retrospective cross-sectional study was conducted using lateral cephalograms of 230 subjects with growth potential (110 males, 120 females). Subjects were categorized into three classes (Class I = 81, Class II = 82, Class III = 67), according to the sagittal relationship established between the maxilla and the mandible. The cervical vertebral maturation stage was recorded by means of Baccetti's method. The mean ages at CS3 and CS4 and the CS3-CS4 age interval were compared between boys and girls and among three skeletal classes. Results: Pubertal growth peak occurred on average four months earlier in girls than boys (p = 0.050). The average duration of pubertal growth peak was 11 months in Class I, seven months in Class II and 17 months in Class III subjects. Interclass differences were highly significant (Cohen's d > 0.08). However, no significant difference was found in the timing of pubertal growth peak onset among three skeletal classes (p = 0.126 in boys, p = 0.262 in girls). Conclusions: Girls enter pubertal growth peak on average four months earlier than boys. Moreover, the duration of pubertal growth peak is on average four months shorter in Class II and six months longer in Class III subjects as compared to Class I subjects.

e15530 Background: CTCs have been widely used in monitoring the efficacy and prognosis of lung cancer. However, CTCs number count alone cannot accurately predict the recurrent disease in patients. In this study, we investigate whether the morphology classification of CTCs could be as a prognostic marker for increased risk of recurrence after surgery. Methods: In this study, 105 lung cancer patients (median age 68y) who underwent surgery were prospectively enrolled in this study. Samples were obtained before, after, and serially up to 24 months after surgery. CTCs were collected and morphology classified by utilizing a CTC test workflow which uses negative enrichment and immunofluorescence methods to capture and identify CTCs from blood sample. Captured CTCs (epithelial type) were screened with a customized imaging analysis pipeline, a cytological profile of each CTC was created, including cell size, shape, fluorescent intensity and texture etc. Results: The CTC detection rate was 78.1% (78 of 105) prior to surgery, and a total of 726 CTCs were enumerated. Median CTC count number was 3. 5 classes of CTCs with distinct morphological features were observed in lung cancer patients’ CTC tests, briefly, CTC class I and class II possessed large nuclei but relatively lower epithelial expression level, CTC class III, IV, V possessed small nuclei but relatively higher epithelial expression level, CTC class III possessed irregular shaped nuclei, CTC class V possessed relatively lower nuclei/cytoplasm ratio. Class III accounted for the highest proportion of captured CTCs III, about 35.5% with Class I 14.8%, Class II 15.3%,Class IV 17.8% and Class 5 16.6%. Postoperative recurrence and metastasis were observed in 16 patients. CTCs positive were found in 14 patients (87.5%). 145 CTCs were collected, Median CTC count number was 3,Cluster III accounted for 47.3%, with Class I 11.8%,Class II 13.3%,Class IV 14.5% and Class V 11.8%; Patients with Cluster 3 dominant were associated with increased risk of local recurrence ( p < 0.05) and distant metastasis ( p < 0.05). Conclusions: Small and irregular nuclei CTC is significant associated with increased risk of recurrence disease. Morphology Classification of circulating tumor cells is feasible in monitoring the recurrence of disease and may potentially identify the patients who may benefit from further therapy.

ABSTRACT Objective: To assess the effectiveness of Class II subdivision Herbst nonextraction treatment and its short-term stability retrospectively. Materials and Methods: Twenty-two Class II subdivision (SUB: right-left molar difference ≥0.75 cusp width) and 22 symmetric Class II patients (SYM: ≥0.75 cusp width bilaterally) were matched according to gender and pretreatment handwrist radiographic stage. The mean treatment duration of the Herbst and subsequent multibracket phase was 8 months and 14 months, respectively. The mean retention period amounted to 36 months. Dental casts from before treatment (T1), after Herbst treatment (T2), after Multibracket treatment (T3), and after retention (T4) were evaluated. Results: A bilateral Class I or super Class I molar relationship was seen in 72.7% (SUB) and 77.3% (SYM) at T3. The corresponding values at T4 were 63.7% (SUB) and 72.7% (SYM). A unilateral or bilateral Class III molar relationship was more frequent in the SUB group (T3: +4.6%; T4: +13.6%). For overjet, similar mean values were seen in both groups after treatment (T3: SUB, 2.7 mm; SYM, 2.3 mm) and after retention (T4: SUB, 3.0 mm; SYM, 3.4 mm). This was also true for the midline shift (T3: SUB, −0.4 mm; SYM, 0.0 mm; T4: SUB, −0.3 mm; SYM, 0.0 mm). Conclusion: Class II subdivision Herbst treatment was successful similarly to symmetric Class II Herbst treatment. However, a slight overcompensation of the molar relationship (Class III tendency) was more frequent in the subdivision patients (original Class I side).

Construction of urban waterscape parks based on ecological concepts and functions is becoming the tendency of modern urban parks. Unfortunately, there are no suitable evaluation systems for these parks. This study establishes a comprehensive evaluation system for a landscape and its functions via the analytic hierarchy process and the comprehensive index method. The evaluation model consisted of 3 evaluation indexes and 23 evaluation indicators relevant to the landscape characteristics of Houtan Park of the World Exposition 2010 Shanghai, China. The evaluation indicators were monitored from 2006 to 2010, and the results of the investigation led to the following conclusions: the park fulfills a range of desirable functions, and ranks high in aesthetic, economic and societal values; ecological functions were applied well within the landscape, and following ecological restoration and the construction of a functional aquatic ecosystem, the water quality of Houtan River has been continuously purified from inferior class V~ class V to class III~ class I range, while the heavy metals in the sediment were improved from inferior class V~ class V to class I; the biodiversity was improved from 0.72 into 1.49; and the results for other indicators were improved overall. In general, the comprehensive score of the evaluation increased from 1.227 to 4.341. Although minor problems remain to be solved, the results indicate that the design concept and construction methods applied in Houtan Park are well applicable to sustainable landscapes, and the evaluation system as a whole can be extended and applied in similar cases.

The purpose of this study was to investigate some anthropometric variables of student candidates of the Institute of Sport Sciences and Physiotherapy, Faculty of Medicine, University of Tartu in 2017. All anthropometric measurements were made according to the recommendations of R. Martin [7]. Comparison of the height and weight data of the studied subjects with the height and weight norms of Estonia provided by Kaarma et al. [9] revealed that the entrants were taller in height but with the same average weight. In our study, the somatotypes recommended by Kaarma et al. [9] were used for the first time on entrants to the university. Our study found that male student candidates’ body somatotypes were divided into SD classes as follows: small 8.6%, medium 22.9%, large 18.6%; subtypes of pycnomorphic somatotypes: 7.1% in class I, 1.4% in class II, and 8.6% in class III; leptomorphic somatotypes were divided: 11.4% in class I, none in class II and 31.4% in class III. Based on the recommendations of several authors, we calculated the ideal body weight for all the entrants enrolled in the study. Comparison of the average body weight of entrants with the average weight calculated using the ideal weight method revealed an interesting situation. Namely, the mean values calculated using the Devine (1974) formula did not differ statistically significantly from the mean of the measured weights (t=0.101, p> 0.05). Neither did Devine’s (1974) ideal weight and BMI, Rohrer’s index and ponderal index calculated from it, and the body surface calculated according to the formulas of Dubois and Dubois and Mosteller differ from the actual figures.

Purpose of the Investigation To investigate, by questionnaire, the direct restorative materials used by a sample of practitioners from the Unite d Kingdom. Basic Procedures A postal questionnaire was distributed to a group of self-selected practitioners, who volunteered to participate in the study. In all 110 practitioners participated in the study. Main Findings The most used material for the restoration of occlusal (Class I) and approximal (Class II) lesions was amalgam with 61% and 73% of practitioners indicating that they used amalgam in this situation. Adhesive tooth-coloured materials, specifically composites and compomers, were preferred by the majority of practitioners for anterior approximal (Class III) and incisal (Class IV) restorations with compomer preferred for Class V restorations including non-carious cervical lesions and for the restoration of primary teeth. Principal Conclusions It is concluded that the general practitioners surveyed in this study tend to use amalgam for the restoration of Class I and II lesions as opposed to resin composite. The majority of practitioners in this study used compomers, a relatively new group of restorative materials, with little evidence of traditional glass-ionomer cements being used routinely.
