Purpose: The purpose of the study is to evaluate the effects of osteoporosis (OP) using panoramic mandibular index (PMI) and mandibular cortical index (MCI) in panoramic radiographic and cone-beam computed tomographic (CBCT) images and to demonstrate any advantages of CBCT versus panoramic imaging in those indexes. Materials & Methods: 36 female patients (18 with osteoporosis and 18 with no systemic disease) who had panoramic radiographic and CBCT indication due to dental problems were involved in the study. PMI and MCI are evaluated on both panoramic and CBCT images. Differences between patient groups are analyzed by the Kruskal Wallis test, and differences between imaging techniques are analyzed by impaired t-tests ignoring patient groups in confidence interval 95%. Results: In CBCT images, PMIs were significantly lower in patients with osteoporosis than in the control group (p=0.004), and there was no significant difference between the patient and control group in panoramic images (p=0.085). In both imaging techniques, MCIs were significantly higher in the osteoporosis group than in the control group (p=0.000). CBCT showed a significant advantage on PMI to panoramic images (p=0.05). Conclusion: Systemic diseases affect bone tissue in different levels, and to evaluate these effects, cortical and trabecular bone parts must be investigated separately, and findings must be combined with patients’ clinical symptoms. CBCT has advantages in PMI evaluations to panoramic radiography.

Guiding Effect

Abstract Background: To evaluate the guiding effect of digital image based on cone-beam computed tomographic in improving the quality of single oval root canal preparation.Methods: A premolar was selected by CBCT and a 3D-printed root canal model was made. Twenty postgraduates from the Department of Stomatology of Shanghai Ninth People's Hospital were selected to perform root canal preparation on 3D printed oval root canal model teeth. They were randomly assigned to two groups(n=10) according to the guiding method received: CBCT original image (control group) and CBCT-based digital image (experimental group). CBCT scans were performed on the models before and after the guidance. The changes in root canal cleanliness, residual minimum thickness, transportation and over-preparation amount were analyzed.Results: The experimental group caused significantly more increased amount of cleanliness compared to control group(P<0.05)：6.0373% ±6.0766% in the control group and 13.7193%±6.7102% in the experimental group. There was no significant difference in the reduction of residual minimum wall thickness between the two groups (P>0.05)： 0.0154mm±0.2110mm in the control group and 0.0362±0.0444mm in the experimental group. In the control group, the transportation after second preparation was generally increased (increased 0.0084mm on average). In the experimental group, the transportation was generally reduced after second preparation (reduced 0.0081mm on average). But there was no significant difference in the transportation change between the two groups (P>0.05). After the second preparation, there was no significant difference in the amount of increased over-preparation between the two groups（P＞0.05）: 1.7029%±3.6622% in the control group and 3.5144%±4.8075% in the experimental group.Conclusions: Compared with traditional CBCT image guidance, the digital image method can significantly improve the cleaning effect of the oval root canal preparation. It didn’t result in more over-preparation and the amount of residual wall thickness was ensured. At the same time, it has a certain effect on reducing transportation after the guidance.

SummaryBackground/Aim: The aim of this study was to evaluate and compare the imaging characteristics of common, radiolucent, unilocular, intraosseous lesions of the jaws using both panoramic radiography and cone beam computed tomography (CBCT); also, to evaluate sufficiency of panoramic radiography in determining characteristic features of jaw lesions.Material and Methods: Retrospectively selected images of 57 patients with histopathology results were evaluated by two oral radiologists. The lesions were assessed based on shape, location, borders, relationship with the mandibular canal, presence of destruction of cortical bone, and expansion of cortical bone, and presence of an unerupted tooth related to the lesion. In addition, the widest areas of the lesions were measured. A total of 9 (15.8%) odontogenic keratocysts, 9 (15.8%) apical granulomas, 24 (42.1%) radicular cysts, 12 (21.0%) dentigerous cysts and 3 (5.2%) central giant cell granulomas in 57 patients (20 women, 37 men) with a mean age of 36.93 ± 17.96 years were included. Fifty-seven CBCT and 56 panoramic images of these patients were evaluated.Results: Twenty-nine (50.8%) lesions were in the mandible and 28 (49.2%) in the maxilla. A statistically significant difference was determined for the areas in CBCT images (p=0.007).Conclusions: Panoramic radiography is not as successful as CBCT in demonstrating some characteristics of the lesions, such as expansion and destruction. The area measurements may be beneficial in establishing the differential diagnosis of the lesion.

INTRODUCTION We observed that a number of patients presenting to our clinic with diverticular fistulation were taking nicorandil for angna. Recognised side effects of nicorandil include gastrointestinal and genital ulceration. The aim of our study was to determine whether nicorandil is an aetiological agent in diverticular fistulation. PATIENTS AND METHODS We conducted a case-control study of patients with diverticular disease related enteric fistulae. Two patient groups were identified: a study group of patients with diverticular fistulae, and a control group with uncomplicated diverticular disease. The proportion of patients who had ever used nicorandil was compared between the two groups. RESULTS A total of 153 case notes were analysed, 69 patients with fistulae and 84 control patients with uncomplicated diverticular disease. Female to male ratio in both groups was 2:1. The mean age was 71 years in the fistula group and 69 years in the control diverticular disease group (P = ns). Of those with colonic fistulae, 16% were taking nicorandil compared with 2% of the control group (odds ratio 7.8; 95% confidence interval 1.5–39.1; P = 0.008). There was no significant difference in rates of ischaemic heart disease between fistula and control groups. CONCLUSIONS Nicorandil is associated with fistula formation in diverticular disease.

ABSTRACT Objective: The aim of this study was to evaluate the skeletal and dental effects of rapid maxillary expansion (RME) in cleft patients using two types of expanders. Methods: Twenty unilateral cleft lip and palate patients were randomly divided into two groups, according to the type of expander used: (I) modified Hyrax and (II) inverted Mini-Hyrax. A pretreatment cone-beam computed tomographic image (T0) was taken as part of the initial orthodontic records and three months after RME, for bone graft planning (T1). Results: In general, there was no significant difference among groups (p > 0.05). Both showed a significant transverse maxillary expansion (p < 0.05) and no significant forward and/or downward movement of the maxilla (p > 0.05). There was greater dental crown than apical expansion. Maxillary posterior expansion tended to be larger than anterior opening (p < 0.05). Cleft and non-cleft sides were symmetrically expanded and there was no difference in dental tipping between both sides (p > 0.05). Conclusions: The appliances tested are effective in the transverse expansion of the maxilla. However, these appliances should be better indicated to cleft cases also presenting posterior transverse discrepancy, since there was greater expansion in the posterior maxillary region than in the anterior one.

Research objective. The study aimed to evaluate cone-beam computed tomography (CBCT) capabilities in diagnostics of cystic masses of the jaw.Methods. Over a period of 2015–2016 32 patients age 6 to 67 underwent both panoramic tomography and CBCT (using panoramic tomographic scanner STRATO 2000 and cone-beam computed tomographic scanner i-Cat respectively). 47% (n = 15) of the participants were women, 53% (n = 17) – men. Radiation exposure for a single procedure amounts to 0,05 mSv for panoramic tomography, 0,07 mSv for CBCT (FOV =13 cm), 0,06 mSv for CBCT (FOV =8 cm).Results. Comparative analysis of obtained results demonstrates that CBCT showed 54% (n = 27) more cystic masses of the jaws than panoramic radiography could. CBCT additionally showed the following pathologies: granulomas smaller than4 mm diameter – 85% (n = 23), 83% (n = 23) of said granulomas were found on maxilla, radicular cysts of maxilla – 11% (n = 3), incisive canal cyst – 4% (n = 1). Additionally panoramic tomography analysis misdiagnosed 5 granulomas (80% (n = 4) on mandibular premolar and molar areas) that were not found during CBCT analysis.Conclusion. The low effective dose and high informativity of CBCT enables the method to be used instead of intraoral radiography, panoramic tomography and MSCT as a screening procedure in diagnostics of dento-facial system pathologies, including cystic masses of the jaw.

Background: Amplification of inflammation in acute exacerbation of chronic obstructive pulmonary disease (COPD) increases inflammatory mediators and oxidative stress in the airways, pulmonary and systemic circulation that are characterized by increased plasma level of IL-6 and MDA, resulting in worsening of clinical symptoms. Xanthones in mangosteen pericarp have anti-inflammatory and antioxidant effects, potentially as an adjuntive therapy in acute exacerbations of COPD. Methods: The aim of this study was to determine the effect of mangosteen pericarp extract to clinical improvements, plasma level of IL-6 and MDA of acute exacerbation COPD patients. A clinical trial of experimental with pretest and posttest was conducted on 34 acute exacerbation of COPD patients in Dr. Moewardi Hospital Surakarta and Dr. Ario Wirawan Lung Hospital Salatiga from April until May 2016. The sample was taken by consecutive sampling. Subjects were divided by randomized double blind technique into the treatment group (n=17) received mangosteen pericarp extract 2x1100mg/day and control group (n = 17) received placebo. Clinical improvements were measured in CAT score and length of stay. CAT score, plasma level of IL-6 and MDA were measured on admission and at discharge. Length of stay based on the number of days of care in hospitals. Results: There was significant difference (p=0,011) towards decreased of IL-6 plasma level between treatment group (-2,17 ± 3,46 pg/ mL) and control group (+1,67 ± 6,81 pg/mL). There were no significant difference towards decreased of length of stay (p=0,34) between treatment group (4,12 ± 1,54 days) and control group (5,24 ± 2,49 days), towards decreased of CAT score (p=0,252) between treatment group (-19,18 ± 3,96) and control group (-18,24 ± 2,75), and towards decreased of MDA plasma level (p=0,986) between treatment group (+0,03 ± 0,36μmol/L) and control group (+0,35 ± 1,58). Conclusions: The addition of mangosteen pericarp extract 2x1100mg/day during hospitalization was significantly lowered plasma levels of IL-6, but were not significant in lowering the CAT score, shortening the length of stay, and reducing the increase in plasma level of MDA.

Background: Gingival crevicular fluid (GCF) is a biological fluid derived from the gingival sulcus and can be elevated in the inflammatory state of periodontal tissue, such as gingivitis. In previous studies, the number of GCF could also increase after panoramic radiographic exposure. Increase in GCF due to panoramic radiography is a sign of cell damage. Objective: To analyze the effects of panoramic radiography on the volume of GCF in wistar rats with gingivitis. Method: This type of research was true experimental with post test only and control group design. The sampling technique used was simple random sampling. A total of 25 wistar rats were classified into two control groups without exposure (state without gingivitis and gingivitis) and three groups treatment of exposure (state of gingivitis with 1 time, 2 times, and 3 times the exposure). GCF sampling using filter paper was carried out 10 minutes after panoramic radiographic exposure. The filter paper was stained by 2% ninhydrin solution, after that the GCF volume was calculated. Results: There was a significant difference in the number of GCF (p<0.05) in the group without gingivitis and exposure compared to all other groups, the gingivitis group without exposure compared to the gingivitis group with 3 times exposure, and the gingivitis group with 1 time exposure compared to the gingivitis group 3 times with exposure. Conclusion: Panoramic radiography can cause an increase in the volume of GCF in wistar rats with gingivitis. Keywords: GCF, gingivitis, panoramic radiography

 Objective: Investigate the effectiveness of nursing risk management in the care of critically ill patients in the respiratory unit. Methods: Among the critically ill respiratory patients admitted to our hospital between May 2019 and April 2020, 78 patients were randomly selected and divided into an observation group and a control group, each consisting of 39 patients. In the observation group, a nursing risk management model was implemented, i.e., patients' clinical symptoms were observed at any time to monitor their treatment satisfaction and the effectiveness of their care and routine care was implemented for the control group. Results: The heart rate, respiratory rate, and pH of patients in the observation group were more stable than those in the control group, and their respiratory status was better, with differences in data. There was also significant statistical significance (P<0.05). The incidence of patient-provider disputes, unplanned extubation, and unplanned events were lower in the observation group compared to the control group, and their data difference was statistically significant (P<0.05). The treatment satisfaction as well as the total effective rate of patients in the observation group was also much higher than that of the control group, and there was also a statistically significant difference in the data (P<0.05). Conclusion: The nursing risk management model has a significant therapeutic effect in the care of critically ill respiratory patients. Therefore, it is worth popularizing to use in the clinical nursing of respiratory critical patients.

Objective: to evaluate vasopressin (VP) concentration in patients with varying severity of chronic heart failure (CHF), intensity of clinical symptoms, and decreased level of left ventricular ejection fraction (LVEF). Materials and methods. In total, 120 patients (44 males, 76 females) with CHF of varying genesis (mean age 72.12 ± 10.18 years) and 30 clinically healthy individuals (18 males, 12 females) as a control group (mean age 33.4 ± 6.23 years) were examined. All patients underwent comprehensive clinical and instrumental examination in accordance with the standards for patients with CHF. The VP level was determined using ELISA. Statistical analysis was performed using the IBM SPSS Statistics v. 23 software.Results. The patients with CHF had significantly higher blood VP levels compared to the control group (72.91 ± 53.9 pg/ml versus 6.6 ± 3.2 pg/ml respectively; p <0.01). At the same time, patients with stage III CHF had significantly lower VP levels than patients with stages IIВ and IIА (35.61 ± 21.53 pg/ml versus 71.67 ± 48.31 pg/ml and 86.73 ± 59.78 pg/ml respectively; p<0.01). A similar picture was observed for the functional classes (FC). For instance, for CHF FC II and III, the VP level was 91.93 ± 67.13 pg/ml and 77.95 ± 54.01 pg/ml respectively, while for FC IV it decreased to 50.49 ± 28.18 pg/ml (p <0.01). The VP concentration in patients who subsequently perished was significantly lower than in patients who survived (48.79 ± 26.30 pg/ml versus 79.72 ± 57.73 pg/ml; p = 0.012). Moreover, in patients with LVEF <50 %, the VP level was significantly lower than in patients with LVEF >50 % (59.43 ± 42.51 pg/ml versus 86.43 ± 62.46 pg/ml respectively; p <0.05).Conclusion. The observed significant differences in VP in patients with stage III and IV CFH can indicate depletion of neurohumoral mediators in this patient category. However, a correlation between the VP level and the level of LVEF decrease can indicate a significant difference in the role of VP in CHF pathogenesis in patients with preserved and decreased LVEF. This observation requires further research.

Our objective was to investigate the concentrations of IgA and IgG antibodies to Saccharomyces cerevisiae in whole saliva and serum samples from HIV-infected patients and to compare them with the corresponding antibody values of healthy controls. A cross-sectional design was used. The test group consisted of 23 HIV-infected male individuals, aged 20-41 years old, free of any other systemic disease. Twenty healthy subjects aged 27-43 years old served as controls. Whole unstimulated saliva and blood were collected from all subjects. IgA concentrations in saliva and IgA and IgG concentrations in serum were measured by solid-phase enzyme-linked immunosorbent assay. Salivary antibody concentrations were calculated by reference to a pooled standard saliva obtained from 10 healthy males with high levels of anti- S. cerevisiae antibody activity. Total IgA and IgG concentrations were measured by nephelometry/tholocymetry assay. No significant difference was observed in salivary specific IgA and serum specific IgG levels to S. cerevisiae, while serum specific IgA were significantly lower in HIV infected patients compared to control group. Opportunistic infections due to S. cerevisiae, although rare, cannot be dismissed. This yeast can show a potential virulence in debilitated patients, therefore, further extensive investigation should be considered.
