Optimal antero-posterior position of the maxillary central incisors and its relationship to the forehead in adult African American females

ABSTRACT Objectives: To determine an optimal anteroposterior (AP) position of the maxillary central incisors and their relationship to the forehead in adult African American (AA) females. Materials and Methods: Smile profile photographs of 150 AA females were acquired and divided into an optimal control group (N = 48) and a study group (N = 102) based on the position of the maxillary central incisors, as judged by a panel of orthodontists and orthodontic residents. The AP position of the maxillary central incisors and the forehead inclination (FI) were measured relative to Glabella vertical (GV). A two-sample t-test was used to compare the incisor AP position and the FI between the two groups. Linear regression was used to quantify the relationship between the incisor AP position and the FI. Results: In all groups, the maxillary incisors were anterior to GV. However, a significant difference was found in the incisor AP position between the groups (8.58 ± 3.96 mm for the control group and 11.2 ± 4.48 mm for the study group; P = .001). Furthermore, the control group demonstrated a positive association between the optimal AP position of the maxillary central incisors and FI (P < .0001). Conclusions: GV is a reliable landmark with which to access the AP maxillary incisor position in AA females. The optimal AP position of the maxillary central incisors is significantly associated with FI; the greater the FI, the more anterior the optimal maxillary incisor position. A prediction equation to determine the optimal position of the maxillary incisors relative to GV for AA females is proposed.

ABSTRACT Objective To investigate the efficiency of platelet-rich fibrin (PRF) injection on maxillary incisor retraction rate. Materials and Methods The study included 40 patients (23 women and 17 men; mean age; 20.7 ± 1.45) with Class II Division 1 malocclusion. The treatment plan for all patients was extraction of the maxillary first premolars and canine distalization, followed by retraction of the maxillary incisors. Patients were randomly divided into two groups. The study group received injectable platelet-rich fibrin (i-PRF) two times with an interval of 2 weeks; the control group did not receive i-PRF. In both groups, the measurements were bilaterally assessed as the distances between the lateral and canine teeth on the plaster models at five time points. The rate of incisor movement was evaluated by Student's t-test, analysis of variance, and Tukey honestly significant difference tests. Statistical significance was set as P < .05. Results The average movements of incisors were significantly higher in the study group than the control group at all time points (P < .05). According to the within-group comparison, none of the measurements showed any significant differences between the right and left sides in both groups at all time points (P > .05). While the movement of incisors was significantly higher in the study group in the week following the PRF injection compared to the other weeks (P < .05), there were no significant differences in the control group at all-time points (P > .05). Conclusions Applying i-PRF significantly increased the rate of maxillary incisor retraction at all time intervals. Platelet-rich fibrin injection can be an effective method for shortening treatment duration.

Objective Investigation

Objective. Investigation of the relationship between the first trimester complete blood count parameters and miscarriage. Materials and Methods. The study group consisted of 39 patients who admitted to the hospital with the diagnosis of abortus imminens between January 2016 and December 2019, and whose pregnancy ended as miscarriage before the 20th week. The control group consisted of 200 randomly selected healthy pregnant women, with follow-up and delivery in our hospital. Patient information was obtained retrospectively from the hospital records. Results. Age and BMI of both groups were similar. There was no significant difference between the two groups in terms of basophil, neutrophil, eosinophil, lymphocyte, monocyte, platelets, RBC, hemoglobin, hematocrit, MCV, MCH, MCHC, RDW, MPV, Pct and PDW, while leukocyte and neutrophil counts was statistically significantly higher in the miscarriage group (p=0,002, p=0,001, respectively). NLR was statistically higher in the miscarriage group (p=0,005), PLR was also higher in the miscarriage group, but this did not reach statistical significance (p=0,056). Both groups were similar in terms of MLR. Conclusions. High NLR levels obtained from the hemogram results in the first trimester seems to be associated with miscarriage. NLR can be an easy, cheap and useful tool for predicting pregnancy prognosis in patients with abortus imminens.

ABSTRACT Objective: To examine the effect of maxillary incisor proclination due to orthodontic treatment upon the sagittal position of point A and evaluate the effect of this possible movement of point A on sella-nasion-point A (SNA) angle. Materials and Methods: A study group was formed from 25 subjects (12 male and 13 female) who had Class II division 2 malocclusion with retroclined upper incisors, and a control group was formed from 25 subjects (12 male and 13 female) who had minor crowding in the beginning of the treatment and required no or minimal maxillary anterior tooth movement. Treatment changes in maxillary incisor inclination, sagittal position of point A, SNA angle, and movement of incisor root apex and incisal edge were calculated on pretreatment and posttreatment lateral cephalographs. Results: Maxillary incisors were significantly proclined (17.33°) in the study group and not significantly proclined (1.81°) in the control group. This proclination resulted in 2.12-mm backward movement of the root apex and 5.76-mm forward movement of the incisal edge of maxillary incisors. Point A moved 1.04 mm backward (P = .582) and 0.48 mm (P = .811) forward in the study and control groups, respectively. Incisor root apex and incisal edge almost remained stable in the control group. No significant change was observed in the value of the SNA angle in both the study and control groups. Conclusions: Proclination of maxillary incisors accompanied by backward movement of incisor root apex caused posterior movement of point A. However, this posterior movement does not significantly affect the SNA angle.

Abstract Introduction Good hearing in pilots, including central auditory skills, is critical for flight safety and the prevention of aircraft accidents. Pure tone audiometry alone may not be enough to assess hearing in the members of this population who, in addition to high noise levels, routinely face speech recognition tasks in non-ideal conditions. Objective To characterize the frequency-following response (FFR) of a group of military pilots compared with a control group. Methods Twenty military pilots in the Study Group and 20 non-pilot military personnel, not exposed to noise in their work, in the Control Group, all with normal hearing, aged between 30 and 40 years old, completed a questionnaire to assess their hearing habits, and their FFRs were measured with a /da/ syllable (duration 40 milliseconds, speed 10.9/s), at 80 dB NA in the right ear. All procedures were approved by the ethical committee of the institution. Statistical analysis was performed using the t-Student or Mann-Whitney tests for quantitative variables, and the Fisher or chi-squared tests for qualitative variables, and a value of p < 0.05 was considered to be statistically significant. Results There was no significant difference between the groups regarding auditory habits. In the FFR, wave amplitudes A (p = 0.01) and C (p = 0.04) were significantly lower in the Study Group. Conclusion Working as a military pilot can be a crucial factor in determining an individual's typical FFR pattern, demonstrated in the present study by statistically significant reductions in the amplitudes of the A and C waves.

Background and Purpose: Lactobacilli play a vital role in protecting the vagina against pathogens. Cytokines are vital components of defense against infections in women. The genital mycoplasmas, Mycoplasma genitalium and Ureaplasma urealyticum, are associated with various infectious diseases in adults and infants. The objective of our study is to identify differences in cytokine profile and Lactobacillus species dominance between a study group of non-pregnant pre-menopausal women with genital M. genitalium or U. urealyticum colonization and a control group of non-pregnant pre-menopausal women without genital M. genitalium or U. urealyticum colonization. Methods: A real-time polymerase chain reaction was performed to measure Lactobacillus species in vaginal swab samples. Cytokine analysis was performed using multiplex immunoassay techniques. Analysis of variance confirmed a significant difference in cytokine profiles between patient groups, with t-tests identifying the most significantly different cytokines. Categorical data analysis identified significant patterns of relative Lactobacillus species dominance in the study group. Results: Lactobacillus iners was the predominant Lactobacillus species in the control group ( p = 0.005). There were no dominant Lactobacillus species observed in the study group. Vascular endothelial growth factor A ( p = 0.002), interleukin-8 ( p = 0.001), and interleukin-1β ( p = 0.049) were expressed significantly higher in the study group, whereas interleukin-1 receptor antagonist ( p < 0.001), interleukin-10 ( p = 0.001), interleukin-12 ( p = 0.002), and interferon-γ ( p = 0.022) were expressed higher in the control group. Association matrices for cytokines were significantly different between two groups ( p < 0.001), with mostly negative associations in the control group and mostly positive associations in the study group. Conclusion: Cytokine levels, their associations, and the patterns of Lactobacillus species dominance are observed to significantly diverge on the basis of M. genitalium and U. urealyticum colonization among non-pregnant pre-menopausal women.

Margin Cytology

Purpose: To evaluate the tear parameters, meibomian glands and lid margin and tarsal conjunctival impression cytology in patients with conjunctivochalasis (CCH). Methods: The study included 57 patients diagnosed with CCH and 35 healthy volunteers. Tear break-up time (TBUT) was measured and Schirmer test was performed. Meibomian gland morphologies, dropout rates, and meiboscores were evaluated using meibography. Finally, impression cytology samples were taken by pressing the impression filters on the lower lid margin and lower tarsal conjunctiva. The samples were evaluated according to the Nelson grading system. Results: Schirmer test was longer and TBUT was shorter in the study group ( p = 0.035 and p < 0.001, respectively). The median of meibomian gland dropout rate was 33.45% (Interquartile range [IQR]; 23.17%–49.75%) and 18.80% (IQR; 12.35%–26.50%) in the study and control groups, respectively ( p < 0.001). There was no significant difference in terms of lid-margin cytology between the two groups ( p = 0.481). In tarsal conjunctiva cytology, the median value of Nelson grade of the study group was 2 (IQR; 1–2) and that of the control group was 1 (IQR; 1–2) ( p = 0.040). When Nelson grade-2 and above was accepted as the pathological limit, it was found that 27.5% of the study group and 15.2% of the control group showed pathological findings ( p = 0.204). Conclusions: In patients with CCH, damage occurs in the tarsal conjunctiva with the effects of redundant conjunctival folds. In these patients, atrophy occurs in the meibomian glands and tear stability is impaired. Therefore, CCH should not be overlooked in clinical practice.

Abstract Objective: The unprecedented occurrence of a global pandemic is accompanied by both physical and psychological burdens that may impair quality of life. Research relating to COVID-19 aims to determine the effects of the pandemic on vulnerable populations who are at high risk of developing negative health or psychosocial outcomes. Having an ongoing medical condition during a pandemic may lead to greater psychological distress. Increased psychological distress may be due to preventative public health measures (e.g. lockdown), having an ongoing medical condition, or a combination of these factors. Methods: This study analyses data from an online cross-sectional national survey of adults in Ireland and investigates the relationship between comorbidity and psychological distress. Those with a medical condition (n128) were compared to a control group without a medical condition (n128) and matched according to age, gender, annual income, education, and work status during COVID-19. Participants and data were obtained during the first public lockdown in Ireland (27.03.202008.06.2020). Results: Individuals with existing medical conditions reported significantly higher levels of anxiety (p<.01) and felt less gratitude (p.001). Exploratory analysis indicates that anxiety levels were significantly associated with illness perceptions specific to COVID-19. Post-hoc analysis reveal no significant difference between the number of comorbidities and condition type (e.g. respiratory disorders). Conclusion: This research supports individualised supports for people with ongoing medical conditions through the COVID-19 pandemic, and has implications for the consideration of follow-up care specifically for mental health. Findings may also inform future public health policies and post-vaccine support strategies for vulnerable populations.

To investigate the effect of aerosol inhalation of budesonide suspension on clinical efficacy, remission time of asthma and disappearance time of rales in children with mycoplasma pneumoniae pneumonia. Methods: 100 cases of mycoplasma pneumoniae pneumonia in our hospital from February 2019 to February 2021 were randomly divided into study group (n = 50) and control group (n = 50). The control group was given azithromycin intravenous drip followed by oral treatment, and the study group was given aerosol inhalation of budesonide suspension on the basis of the control group. Results: Compared with the control group, disappearance time of rales in the study group, remission time of cough, remission time of asthma and time of hospitalization in the study group were relatively short (P<0.05), and the efficacy in the study group was relatively high (P<0.05). There was no significant difference in the incidence of nausea, vomiting, abdominal pain, diarrhea and hoarseness between the two groups (P>0.05). The improvement of FVCS FEV1 and PEF and other indexes was relatively high in the study group by comparing with the control group (P<0.05). Conclusion: Aerosol inhalation of budesonide suspension in children with mycoplasma pneumoniae pneumonia can effectively enhance the therapeutic effect, promote the improvement of lung function, and reduce the disappearance time of rales and remission time of asthma, so it can be popularized.

Respiratory Exercises

Background/aims Workers engaged in vehicle spray painting are at a risk of developing respiratory problems because of the solvents in the spray paints. Changes in respiratory functions and functional capacities caused by spray painting can be improved with respiratory exercises. The aim of this study was to examine the effects of respiratory exercises on the respiratory functions, functional capacity and quality of life in vehicle spray painters. Methods A total of 70 volunteers with similar characteristics participated in the study. The groups were divided into two groups randomly (35 study group, 35 control group). Respiratory functions (value of forced expiratory volume percentage in 1 second [FEV1]), forced vital capacity percentage [FVC], FEV1/FVC percentage, peak expiratory flow percentage [PEF (%)] and maximum voluntary ventilation percentage [MVV (%)]), functional capacity (6-Minute Walk Test) and quality of life (Short Form Health Survey [SF-36]) were evaluated. The study group undertook supervised breathing exercises 3 days a week for 6 weeks. The same exercises were given to the control group as a home programme. Home programmes were followed up by telephone calls. Evaluations were performed again after 6 weeks. Results In the study group, FEV1 (%) increased more than in the control group (P<0.05). The increase in PEF (%) was similar in both groups (P>0.05). In the study group, FEV1/FVC (%) and MVV (%) were significantly different before and after the intervention (P<0.05), but there was no difference in the control group (P>0.05). There was a greater increase in the study group than in the control group (P<0.05). 6-Minute Walk Test distance (m) before and after the intervention in both groups were similar (P>0.05). Before and after the intervention, a significant difference was found in the vitality and the social function domains of the SF-36 in the study group. In the comparisons of groups, a significant difference was found in the study group in the role-emotional, social function and bodily pain domains of the SF-36 after the intervention (P<0.05). Conclusions Breathing exercises can be recommended for vehicle spray painters to avoid an increase in respiratory resistance and to improve their quality of life.
