Clear Aligner

Background. The composite attachment loss during orthodontic clear aligner therapy is an adverse event that commonly happens in our daily practice. However, there is a lack of related statistical analysis and studies analyzing the related risk factors. Therefore, the aim of this study is to assess the incidence of attachment loss during orthodontic clear aligner therapy and to identify rick factors that may predict such event. Materials and Methods. The demographics and clinical variables of 94 patients undergoing clear aligner therapy (27 males and 67 females; average age: 27.60 ± 0.86   years ) were recorded. Both patient-related and tooth-related attachment loss was recorded. The chi-squared test and logistic regressive analysis were applied to identify the potential risk factors. SPSS for Mac (version 23.0, IBM, USA) was used for statistical analyses. P < 0.05 was considered statistically significant. Results. Our study suggested that the risk factors for attachment loss include frequent aligner removal (≥ 5 times a day) ( losing   rate = 60.0 % , P = 0.005 ), aligner wear time less than 18 hours a day ( losing   rate = 50.8 % , P = 0.014 ), eating without aligners inserted ( losing   rate = 47.9 % , P = 0.034 ), utilizing aligner tray seaters ( losing   rate = 48.2 % , P = 0.006 ), and unilateral mastication ( losing   rate = 52.1 % , P = 0.002 ). The multivariable logistic regression analysis indicates that aligner wear time less than 18 hours a day ( P = 0.020 , B = 0.925 ), using aligner tray seaters ( P = 0.007 , B = 1.168 ), and unilateral mastication ( P = 0.034 , B = − 0.458 ) were considered independent factors that can predict the composite attachment loss in orthodontic clear aligner therapy. Conclusion. Wearing aligner less than 18 hours a day, using aligner tray seaters, and unilateral mastication may contribute to increased incidence of composite attachment loss during orthodontic clear aligner therapy.

Tooth Extractions

Background: The aim of this study was to evaluate oral status, the reasons for tooth extractions and related risk factors in adult patients attending a hospital dental practice. Methods: 120 consecutive patients ranging from 23 to 91 years in age (mean age of 63.3 ± 15.8) having a total of 554 teeth extracted were included. Surveys about general health status were conducted and potential risk factors such as smoking, diabetes and age were investigated. Results: a total of 1795 teeth were missing after extraction procedures and the mean number of remaining teeth after the extraction process was 16.8 ± 9.1 per patient. Caries (52.2%) was the most common reason for extraction along with periodontal disease (35.7%). Males were more prone to extractions, with 394 of the teeth extracted out of the total of 554 (71.1%). Male sex (β = 2.89; 95% CI 1.26, 4.53; p = 0.001) and smoking habit (β = 2.95; 95% CI 1.12, 4.79; p = 0.002) were related to a higher number of teeth extracted. Age (β = −0.24; 95% CI −0.31, −0.16; p < 0.001) and diabetes (β = −4.47; 95% CI −7.61, −1.33; p = 0.006) were related to a higher number of missing teeth at evaluation time. Moreover, periodontal disease was more common as a reason of extraction among diabetic patients than among non-diabetic ones (p = 0.04). Conclusions: caries and periodontal disease were the most common causes of extraction in a relatively old study population: further screening strategies might be required for the early interception of caries and periodontal disease.

Syncope Episode

Syncope in a worker undertaking risky tasks may result in fatalities for the individual or for third parties. We aimed at assessing the rate of syncope recurrence and the risk factors underlying the likelihood of syncope relapse in a working-age population. A prospective cohort of all patients aged 18–65 years consecutively admitted to the Emergency Department for syncope was enrolled. Risk of syncope relapse was assessed at a six-month, 1-year, and 5-year follow-up. Predictors of syncope recurrence have been evaluated at six months and 1 year from the syncope index by a multivariable logistic regression analysis. 348 patients were enrolled. Risk of syncope relapse was 9.2% at 6 months, 11.8% at 1 year, and 23.4% at 5 years. At 6-month follow-up, predictor of syncope recurrence was ≥3 prior lifetime syncope episodes. At 1-year, ≥3 prior lifetime syncope episodes, diabetes mellitus, and anaemia were risk factors for syncope relapse. There was an exceeding risk of recurrence in the first 6 months and a reduced risk of 3.5% per year after the first year. Anaemia, diabetes mellitus, and prior lifetime syncope burden are of importance when giving advice about the resumption of “high risk” jobs following a syncope episode.

167 Background: We have previously shown that consolidation pembrolizumab after chemoradiation is safe in a 93 patient-clinical trial of unresectable stage III NSCLC patients (Durm, ASCO 2016). However 15 patients (16%) developed grade ≥2 pneumonitis. There is limited data on risk factors for developing pneumonitis in this population. We conducted a retrospective review of these patients to identify potential clinical, biologic, radiographic and radiation treatment related risk factors for developing pneumonitis. Methods: We evaluated ECOG PS, age, gender, smoking status, stage, histology, chemo regimen, consolidation chemotherapy, TILs, PDL-1 status, PFTs, PET SUVs, grade of pre-existing ILD, COPD and Radiation dosimetry plans. Logistic regression and fisher’s-exact test were used for the odds ratio and p-values. Results: See Table. [1] [1] Age, histology, stage, chemo, PFTs, SUVs and PDL1 were not significant [2] n = sample size p = pneumonitis [3] Moderate/severe COPD was not seen in any patients with pneumonitis despite 94% of participants being smokers. Conclusions: This preliminary report highlights the utility of a multi-disciplinary approach to develop risk-stratification models for pneumonitis in an at-risk patient population. However larger prospective studies are needed to validate their meaningful use in the clinical setting.[Table: see text]

Sphincter Mechanism

Urinary incontinence, an uncontrolled urine leakage during the storage phase of micturition, is a common condition in female dogs. In intact bitches, the reported prevalence is only 0.2-0.3%, but in spayed bitches it varies between 3.1-20.1%. Most commonly, dogs with acquired urinary incontinence suffer from urethral sphincter mechanism incompetence. This condition seems tobe multifactorial, and although the exact pathophysiology remains unclear, potential risk factors include gender, gonadectomy, breed, body weight, urethral length and bladder neck position. In daily practice, the diagnosis of urethral sphincter mechanism incompetence is usually made after eliminating other potential causes of urinary incontinence. Incontinent bitches are primarily treated with medications, such as alpha-adrenergic drugs, e.g. phenylpropanolamine and oestrogens. Surgery is recommended when patients become refractory to medical treatment.

A Prospective Study

Background: Peripheral Intravenous Catheterization (PIVC) related complication is a common and significant problem in clinical practices. The aim of the study was to see the pattern of complication developed by PIVC and to find out the associated risk factors. Materials & methods: A prospective study was conducted amongst 300 patients and 420 PIVCs were observed. Results: 76 (18.09%) patients developed phlebitis and among the phlebitis patients 55.26% were grade 2 and 22.37% grade 3. Hypertonic fluid infusion and some antibiotics were found as risk factors for phlebitis. Amongst the antibiotics flucloxacilin (60%), amikacin (50%), amoxicillin + clavulanic acid were most common antibiotics responsible for development of phlebitis. Conclusions: Catheterization site and use of antibiotics and potassium chloride with associated co-morbidities are predisposing factors for phlebitis. Better insertion technique may be sought to lower the incidence of PIVC related complications. J MEDICINE JUL 2019; 20 (1) : 29-33

Aim: The aim of this study was to identify variables related to deep periodontal pockets and clinical attachment loss. Materials and methods: The study population consisted of 575 Greek adults, 259 males and 316 females aged 35 to 69 years who referred in a private practice for periodontal treatment. Participants completed a self-administered questionnaire which included several epidemiological variables and underwent an oral clinical examination. The analyses performed by multinomial logistic regression model to estimate the possible associations among the variables examined. Results: 31.3% of the participants showed a mean probing pocket depth of >6.00 mm, and 67.1% showed a mean clinical attachment loss of ≥5.0 mm. Male gender, lower socio-economic status, smoking; irregular dental follow-up and a diabetes mellitus history were consistent statistically significant potential risk factors for probing pocket depth of ≥4.00 mm and clinical attachment loss of ≥3.00 mm. Conclusion: These results confirm previous findings regarding the principal role of cigarette smoking and various epidemiological variables in the etiology of deep periodontal pockets and periodontal loss of attachment.

Low Prevalence

The majority of the almost 400 confirmed cases of infant botulism in the United States have occurred in California, Pennsylvania, and Utah. In Pennsyvania, 44 of 53 (83%) cases occurred within a geographic area of Southeastern Pennsylvania which represents one tenth of the Commonwealth's area and one third of the population at risk for infant botulism. In Southeastern Pennsylvania, a map of the residences of cases circumscribes a discrete ring around Philadelphia. A case-control study performed to seek host-related risk factors, identifies the significant associations of botulism with infants who are white, breast-fed, and born at term into two-parent families with hospitalization insurance. County control studies were performed to identify differences in host-related factors between areas of high and low prevalence of botulism. Although some "protection" could be afforded Philadelphia infants by their feeding and family characteristics, the differences in case rates between Philadelphia and the botulism "ring counties" cannot be explained entirely by host-related factors. Further, the absence of botulism in counties just outside of the botulism "ring," where infants were found to have identical potential risk factors, suggests that an uneven distribution of botulinal spores in the environment is the most significant determinant of case rate.
