Abstract: Objective: CBCT and Mimics software were performed to investigate the incisor root resorption after camouflaged orthodontic treatment of adult skeletal class III malocclusion. Methods: Thirty permanent dentition adult patients with skeletal class III malocclusion were included in orthodontic department. CBCT data of each patient at pretreatment and posttreatment were acquired and three-dimensional (3D) digital models were reconstructed. Image registration was performed of each incisor 3D model before and after camouflaged treatment. Observation, classification and statistics of 3D model overlap were performed, as well as the morphological changes of root resorption were described. Results: (1) Either the upper or lower incisors, slope form resorption had the most percentage (49.17%, 46.67%; 51.67%, 49.16%), followed by cone-shaped form resorption, and flat form resorption had the less percentage. In the upper incisors, the root resorption was mainly in the lingual-labial direction (46.67%, 41.67%), while in the lower incisors, it was in the labial-lingual direction. (2) The result of Kappa consistency test is good (K=0.471, 0.441). Conclusions: The root of the upper and lower incisors showed various morphological changes after camouflaged treatment of adult skeletal class III malocclusion. The absorption was mainly manifested as slope form and cone-shaped form, and flat form resorption can be seen. 3D model registration can be used as a reliable auxiliary method for the morphological study of root absorption.

Abstract: Objective To explore the rationality of Simple Pulmonary Apex Pleural Hypertrophy and Adhered (sPAPHA) in Multi-slice Computed Tomography (MSCT) chest examination of young people (18 – 40 years). Materials and methods Of the 6710 pieces of the chest MSCT data collected from healthy subjects aged 18 to 40 years, 152 were diagnosed with sPAPHA and were divided into two groups (group A and B). Among them, 51 cases showing radiologic pleuroparenchymal fibroelastosis (radio-PPFE) were classified as group A, the remaining 101 cases group B. The image of lung apex, the inclination angle of the median rib (IAR), the anteroposterior to transverse diameter ratio (R) and the shape of cupula pleurae were compared between the two groups. 37 cases of spontaneous pneumothorax were also taken into consideration to observe the pleural cavity adhesions attached to the rough surface. Results The diagnostic rate of sPAPHA was 2.27% and radio-PPFE was 0.76%, accounting for 33.55% of sPAPHA. The pleural thickness of lung apex was 4.69±2.56 mm in group A, greater than 2.86±1.47 mm in group B; the displayed rate of apex line was 76.47% in group A, higher than 3.96% in group B; the size of IAR was (51.42±7.23) in group A, smaller than (59.25±9.37) in group B; the R value was 2.89±1.65 in group A, greater than 2.21±1.02 in group B; and the proportions of arc type and depressed pleural apices were 21.57% and 78.43% in group A, 88.12% and 11.88% in group B. The differences above were of statistical significance (P<0.05). In 37 cases of spontaneous pneumothorax, there were 74 cases of inflated pleural cavity on the rough pleural surface with striated shadow, and 7 cases of pleural cavity adhesion (9.46%). Conclusion The diagnosis of early mild PPFE may be reasonable, as sPAPHA partially presents as radio-PPFE and has flat chest features. Rough pleural surfaces with pleural cavity at the striated shadow could not be used as evidence for the diagnosis of pleural adhesion.

Abstract: Back ground: cholecystectomy for an acutely inflamed gall bladder is accompanied with significant perioperative complications Conservative (non operative management) is considered to be the standard of care mainly in the developed world. Non operative management is still widely practiced in many developing countries including Ethiopia. This study aimed to assess the outcome of such a conservative management in teaching hospitals Addis Ababa, Ethiopia. Method: Hospital based cross-sectional study design was conducted. Data was entered and analyzed by SPSS version 20. Chi-square, binary logistic regression, at 95% CI and P-value <0.05 were used to examine relationship between dependent and independent variables. Results: A total of 134 cases were admitted. In this study the mean age is 41.67, (95% CI 39.5 to 43.9) and M: F ratio is 1:2.2 and Age of the patients ranged between 15-80 years and majority of them were in the age group of 35-44 (32.1%) years. Conservative treatment during index admission was successful in 96.27% of the cases but mean duration of hospital stay 5.54 days, 95% CI (5.03, 6.05). Duration of illness before (OR = 3.47: 1.26-9.55) and Duration of hospital stay (OR = 1.92: 1.28-2.87) were determinant factors for index admission. 19% of patients encountered complication while waiting for cholecystectomy. Comorbidity (AOR = 4.06: 1.49 - 11.07; value = 0.006). GB stone impacted at the neck (AOR = 3.39: (1.259-9.13); value = 0.016) were associated factors identified. In this study out of 131 cases treated and discharged improved and appointed for interval- cholecystectomy only 71.7% of them had interval -cholecystectomy in two-year period. The rest 13 (9.7%) patients did not show up follow up after admission booked (registered under waiting list for bed). 3 patients died with complications directly or indirectly related to conservative management cholecystitis. Conclusion and Recommendations: this study revealed patients arrival to hospital is delayed and also stayed prolonged time in the hospital. significant number of patients also developed complications while waiting for interval cholecystectomy and also significant Number of patients did not get cholecystectomy service. Nationwide introduction of emergency laparoscopic cholecystectomy and Patient referral system, admission, discharge and follow up system needs revision.
