Oral Rehabilitation of an Adult Cleft Palate Patient with Zygomatic Implant-supported Obturator Prosthesis: A Case Report

alwin shared this article with you from Inoreader Oral Rehabilitation of an Adult Cleft Palate Patient with Zygomatic Implant-supported Obturator Prosthesis: A Case Report Via Journal of Oral and Maxillofacial Surgery With advancement in medical services and their accessibility across the country, as well as growing awareness among the patient population, it is rare to find an adult with an untreated cleft lip and/or palate nowadays. Treatment of these patients to restore form and function can be challenging, often yielding less-than-satisfactory outcomes. In current literature, there have been case reports of patients with atrophic maxilla or severe maxillary defects after oncologic resections, where zygomatic implants have been utilized for fabrication of a fixed maxillary prosthesis.

Modified Lip Revision Surgery For The Severe Whistle Lip Deformity In Bilateral Cleft Lip

alwin shared this article with you from Inoreader Modified Lip Revision Surgery For The Severe Whistle Lip Deformity In Bilateral Cleft Lip Via Journal of Oral and Maxillofacial Surgery Whistle deformity is a sequela of primary surgical repair of the bilateral cleft lip that leads to a vertical tissue deficiency and a non-functional orbicularis oris muscle in the medial portion of the upper lip. This sequel is significantly limiting functionally and esthetically. We propose a complete labial revision with a secondary cheiloplasty of Mulliken and a submucosal inferiorly based flap in the central tubercle to increase the volume at this usually deficient area.

Intraoperative flap warming: The novel use of a sterile cardiac forced warm air blanket for maintaining optimal flap perfusion.

alwin shared this article with you from Inoreader Intraoperative flap warming: The novel use of a sterile cardiac forced warm air blanket for maintaining optimal flap perfusion. Via Journal of Oral and Maxillofacial Surgery The two-team approach in major head and neck/reconstructive surgery can occasionally lead to delays between flap harvest and detachment, due to the complexity and length of the ablative procedure. In order to minimize the potential for flap cooling and the adverse impact on microcirculation, active warming can be beneficial.(1) Intraoperative flap warming to either maintain or improve circulation during free flap harvesting has been performed with a variety of passive and active techniques,(2) however limitations such as a lack of consistent temperature regulation, lack of sterility, inability to directly visualise the flap or the need for acquisition of new equipment for a niche area meant that an ideal solution was lacking.

Cellular fibroadenoma versus phyllodes tumors: A pre‐operative diagnostic approach based on radiological and cytological features

alwin shared this article with you from Inoreader Cellular fibroadenoma versus phyllodes tumors: A pre‐operative diagnostic approach based on radiological and cytological features Via Diagnostic Cytopathology Abstract Objective This study has been designed in an effort to identify the clinico-radiological and cytological features that could effectively help in differentiating cellular fibroadenoma (CFA) and phyllodes tumors (PT), which have several overlapping characteristics. Method Histologically proven cases of CFA and PT were reviewed. Cytological features were assessed and categorized. Clinical and radiological details were also evaluated and he the two groups were compared statistically. Results A total of 43 FA and 52 PT were specimens were reviewed. Mean age and tumor size for CFA and PT were 26.05 and 36.94 years, and 3.7 and 6.4 cm, respectively. Univariate analysis and regression models revealed that age >30 years, BIRADS grade of 4 or more, marked cellularity of stromal fragments, more than 30% spindle cells in background cell population and presence of traversing blood vessels in stromal fragments increased the odds of a tumor being phyllodes. The binary logistic regression model was able to predict PT accurately in 87.2% cases (p <  .001). Conclusion PT and CFA could be differentiated if cytological findings are cautiously correlated clinically and radiologically. Age, BIRADS category along with assessment of stromal fragments and background population can effectively distinguish between CFA and PT. View on the web Inoreader.

SEARCH FOR EXPERIMENTAL EVIDENCE OF DOSE-RATE AND WALL SCATTERING EFFECTS IN THE THERMOLUMINESCENCE RESPONSE OF LIF:MG,TI (TLD-100)

alwin shared this article with you from Inoreader SEARCH FOR EXPERIMENTAL EVIDENCE OF DOSE-RATE AND WALL SCATTERING EFFECTS IN THE THERMOLUMINESCENCE RESPONSE OF LIF:MG,TI (TLD-100) Via Radiation Protection Dosimetry Abstract An experimental investigation into the possibility of dose-rate effects and wall scatter in the thermoluminescent response of LiF:Mg,Ti (TLD-100) was carried out. The investigation was motivated by theoretical simulations predicting the possible presence of dose-rate effects coupled with the lack of detailed experimental studies. The dose rate was varied by changing the source to sample distance, by the use of attenuators, sources of 137Cs of various activities, filtration and the construction of identical geometrical irradiators of Teflon and stainless steel. Four levels of dose in the linear dose response region were studied at 10−2 Gy, 1.5 × 10−2 Gy, 0.1 Gy and 0.5 Gy to avoid complications in interpretation due to supralinearity above 1 Gy. At the dose of 1.5 × 10−2 Gy, the dose rate was varied by five orders of magnitude from 4.9 × 10−3 Gy s−1 to 4.9 × 10− 8 Gy s−1. At the other levels of dose, a one to two orders of magnitude in dose rate was achieved. Within the measurement uncertainty of 5–10%, no dose-rate effects were observed in any of the experimental measurements and no changes in the shape of the glow curve were observed. The maximum wall scatter effect (Teflon to stainless steel) was measured at ~8% within the experimental uncertainty and well below expectations. The results are encouraging with respect to the accurate and reproducible use of LiF:Mg,Ti under various experimental conditions of irradiation. View on the web Inoreader.

THE INFLUENCE OF LOW-DOSE OCCUPATIONAL RADIATION EXPOSURE ON PERIPHERAL BLOOD CELLS IN A COHORT OF CHINESE MEDICAL RADIATION WORKERS

alwin shared this article with you from Inoreader THE INFLUENCE OF LOW-DOSE OCCUPATIONAL RADIATION EXPOSURE ON PERIPHERAL BLOOD CELLS IN A COHORT OF CHINESE MEDICAL RADIATION WORKERS Via Radiation Protection Dosimetry Abstract Objectives The study aims to assess the change of peripheral blood cell numbers following protracted low-dose radiation exposure among medical radiation workers. Methods A cohort of 375 Chinese medical workers were followed for 5 years (2015–19) and recorded the changes in blood cells and cumulative doses. T-test, least significant difference-T test, variance analysis and correlation analysis were utilized in this study. Results Compared with the control group, the white blood cells, hemoglobin counts and the ratio of eosinophils in the study group showed a downward trend. The differences in blood cells between groups were mainly found in the number of red blood cells. In a short cumulative time, such as 1 or 3 years, a correlation between the cumulative dose and the quantity of blood cells was detected, but not at 5 years. Conclusions There is no significant difference in the blood cell count s between different types of work, and the long-term cumulative dose has not been statistically correlated with the number of blood cells. So that the number of peripheral blood cells can no longer be used as a good indicator of radiation damage. View on the web Inoreader. Take back control of your news feed.

DESIGN AND FABRICATION OF A PEDIATRIC THYROID PHANTOM FOR USE IN RADIO-IODINE UPTAKE MEASUREMENT, IMAGE QUALITY CONTROL AND DOSIMETRY

alwin shared this article with you from Inoreader DESIGN AND FABRICATION OF A PEDIATRIC THYROID PHANTOM FOR USE IN RADIO-IODINE UPTAKE MEASUREMENT, IMAGE QUALITY CONTROL AND DOSIMETRY Via Radiation Protection Dosimetry Abstract Estimating internal contamination from 131I for children in nuclear accidents is a crucial subject in the radiation protection field. Throughout this paper, an urgent and simple method was proposed for measuring 131I inside the pediatric thyroid gland by constructing a neck and thyroid phantom. For this purpose, CT scan images of healthy child's thyroids were obtained, and the sizes of different parts were determined by a 3D slicer image processing software. Girls with the body surface area between 0.95 and 1.05 were involved in this study. The fabricated phantom is composed of 5 cylindrical slabs of 2-cm thickness, and several small holes were constructed for TLD dosemeters near the thyroid gland and all other parts of the neck. The phantom was constructed utilizing a 3D printer with acrylonitrile butadiene styrene plastic. The thyroid phantom was filled with radioiodine-131, and calibration curves were plotted for contam ination estimation. A nodular thyroid phantom was also constructed. The nodular phantom or the resolution phantom has 4 removable parts containing cylindrical holes with diameters of 3, 6, 9 and 12 mm. These holes on the thyroid glands can be filled with different activities of radionuclides to serve as hot and cold spots for quality control of nuclear medicine images. The results show that the designed phantom is applicable in different fields such as nuclear image quality and resolution tests, dosimetry and iodine thyroid uptake estimation in nuclear medicine departments, and nuclear emergency monitoring.
