Implant therapy is a commonly based method of replacing missing teeth. A range of physical, chemical, and biological modifications have been applied to the surface of titanium implants to improve their biological performance and osseointegration outcomes. Implant surface characteristics play an important function in several peri-implant cellular and molecular mechanisms. Clinicians are commonly placing dental implants with various surface roughness and modifications including plasma-sprayed, acid-etched, blasted, oxidized, hydroxyapatite-coated, or combinations of these procedures. Surface modifications are to facilitate early osseointegration and to ensure a long-term bone-to-implant contact without substantial marginal bone loss can be accomplished. It is apparent that different modifications have a range of beneficial effects, it is essential to consider at what time point and in what conditions these effects occur. This article reviews existing surface modification technologies of mainstream dental implants and the correlation between implant surface coatings and their performance of osseointegration or anti-bacterial ability it needs to be evaluated.
Objective: To evaluate the potential use of digital and reconstructed three-dimensional printed models as an alternative to conventional plaster models by assessing the accuracy of their linear measurements.
Methodology: Pre-treatment plaster models of 45 patients were selected from the archives of the Department of Orthodontics. Each physical plaster model was scanned and digitized using a three-dimensional (3D) laser surface scanning system (inEOS X5, Dentsply Sirona, Bensheim, Germany). The scanned STL files were later used to reconstruct models by 3D printing using Figure4® standalone 3D printer (3D systems, Rock Hill, South Carolina). Measurements of teeth 11 and 16, the transverse width of the upper jaw between the first molars (MM – intermolar width) and canines (CC – intercanine width) were done manually using a digital vernier caliper (Mitutoyo, Kawasaki, Japan), and the CAD Assistant software (Open cascade, Guyancourt, France). Intra examiner data, Intraobserver variability, and measurement accuracy were evaluated using Intraclass Correlation Coefficient (ICC) analysis was done using SPSS 20.0.
Results: The intraclass correlation coefficients were >0.8 indicating high reproducibility and reliability. Significant differences were found between the physical and the digital models but to a small proportion which were deemed not clinically relevant.
Conclusion: Both the digital models and reconstructed three-dimensional printed models using Figure4® technology were clinically permissible in terms of accuracy and reproducibility. The digital storage, transmission, and treatment planning in an environmentally friendly manner should promote digital over conventional records.
Introduction: Psoriasis is a chronic, common immune inflammatory condition of the skin, affecting 2-3% of the population, with regional variability. Classically, psoriasis presents as one of the following types: plaque, guttate, inverse, pustular or erythrodermic psoriasis. Typically, the patient will present with several symmetric psoriatic plaques on typical areas of the body, leading the clinician towards the diagnosis of psoriasis.
Case report: The present case report series focuses on an atypical presentation of psoriasis noted in 2 patients who presented to our office with a single large, erythematous plaque located on the lower leg. Due to poor response to previous treatment, a biopsy was performed and upon analysis, revealed a diagnosis of psoriasis. The lesions showed significant improvement under local therapy.
Conclusion: In spite of significant research on such a common and seemingly well-understood dermatosis, the present case reports plead for further study with regards to atypical presentations of psoriasis.
Objective: During the COVID-19 pandemic, laboratories have used various extraction and amplification kits, associated with different auxiliary materials. This study aims to investigate how different types of plates may affect RT-PCR performance.
Methods: Data on the positive controls (PCs) of RT-PCR runs for SARS-CoV-2 detection between December 2020 and April 2022 was collected retrospectively in the Molecular biology department of the County Emergency Clinical Hospital of Târgu Mureș’s clinical laboratory. The materials used consisted in MOLgen SARS-CoV-2 (Adaltis) and EliGene COVID19 CONFIRM 500 R amplification kits, 96-well full-skirted white and clear plates, and clear films. Microsoft Excel was used for the database and it included information about Cycle threshold (Ct) and maximum fluorescence. Statistical analysis, performed in MedCalc, consisted of Grubbs test, Kolmogorov–Smirnov Test, F test, T student test, and Mann-Whitney test to compare central tendencies. The significance threshold was set at p<0.05.
Results: The Ct comparison for MOLgen kit white plates vs clear plates: FAM channel- U=1052.5, Z=2.07, p=0.038, medians for white plates and clear plates were 22.80 and 23.25, respectively; ROX channel- U=784, Z=3.21, p=0.001, medians 21.93 and 21.43, respectively; Cy5 channel- U=1028.5, Z=1.95, p=0.518, medians 22.12, 21.75, respectively. For EliGene kit: U=848.5, Z=3.27, p=0.001, medians 28.26 (white plates) and 28.0 (clear plates). Comparison of the maximum fluorescence reached on both kits with white and clear plates computed p values <0.0001.
Conclusions: Between white and clear plates there are statistically significant differences considering Ct values and maximum read fluorescence, but with no impact on test outcome.
The trauma of anterior teeth is a frequent occurrence in young patients. Reattachment of fractured fragments is one of the various treatment modalities proposed in anterior tooth coronal fractures. The reattachment of fractured fragments grants the advantage of immediate aesthetic rehabilitation and restoration of function, which is a relatively rapid and less arduous procedure. The manuscript presents a case report depicting the management of a complicated crown root fracture of anterior maxillary teeth first treated endodontically, followed by reattachment of the same fragment with a cast post-reinforcement. Reattachment of fractured coronal tooth fragments is a feasible restorative option, rapidly restoring the function and aesthetics of the tooth by a conservative and inexpensive approach.
Introduction: Pheochromocytomas are catecholamine-secreting tumors arising from the chromaffin cells of the adrenal medulla. We describe an unusual case of pheochromocytoma located in the infrarenal area and associated with bilateral adrenal hyperplasia.
Case presentation: A 70-year-old patient was admitted for syncope, diaphoresis, and high blood pressure. Computed tomography showed a 73x70x72 mm retroperitoneal mass of the left infrarenal area. High levels of metanephrine and noradrenaline were found in the urine. A tumor resection was performed. A few days after surgery, the blood pressure suddenly decreased and could not be restored, resulting in the death of the patient. Histopathological examination of the surgical specimen revealed a proliferation of monotonous cells, with eosinophilic cytoplasm, round nuclei with prominent nucleoli arranged in clusters, and capsular and vascular invasion. The tumor cells expressed synaptophysin and chromogranin, without positivity for inhibin A or S100 protein. At the autopsy, both adrenal glands showed hyperplasia but unrelated to the tumor mass. The histological aspect, location, and immunophenotype indicated an ectopic infrarenal pheochromocytoma.
Conclusions: In patients with pheochromocytoma developed on ectopic adrenal tissue, clinical management might be difficult, and diagnosis can be sometimes established only based on post-mortem histopathological examination. Autopsy can be extremely useful in such cases with unexplained evolution.
Introduction: Acute pancreatitis is a condition that leads to multiple organ failure syndromes if not diagnosed and treated correctly. The most frequent causes of acute pancreatitis are gallstones, alcohol consumption, and elevated triglyceride serum level.
Case Presentation: A 21-year-old female presented to the emergency department with epigastric pain, nausea, vomiting, and diaphoresis. The patient had a non-complicated vaginal birth four months prior, had no personal history of illness, reported no alcohol consumption, and had a slender body constitution. Laboratory tests outlined a white blood cell count of 22.000/µL, elevated neutrophil count, lactate dehydrogenase 294 U/L, and lipemic serum sample reported for chemistry laboratory test. In addition, the contrast-enhanced computed tomography scan revealed severe pancreatitis, with an intraabdominal fluid collection.
Conclusions: This case report highlights the importance of correct early diagnosis in the postpartum and late postpartum period and raises awareness concerning the possibility of acute pancreatitis in a postpartum woman even if she does not have the two most common risk factors: gallstones or alcohol consumption.
Aim: Most pregnant women can achieve their caloric and nutritional needs by careful food choices during pregnancy, but there are fairly common situations when pregnant women develop anaemia, which needs to be managed properly to avoid maternal-foetal complications. The main objective of the study was to identify the nutritional factors favoring the occurrence of iron deficiency anaemia in pregnant women.
Methods: Data collection for the cross-sectional study was carried out using a questionnaire that provided information on nutrition and risk factors during pregnancy in a group of patients from Suceava. The questionnaire was given to pregnant women admitted to the Emergency County Hospital „Sfântul Ioan cel Nou” Suceava, Romania, between March and May 2017.
Results: The anaemia occured in 46.3% of pregnant women. Although 22.2% of pregnant women received oral iron supplementation, effects on anaemia correction were not observed (p=0.02). We found that weight status did not influence anaemic status (p=0.51), and the presence of anaemia in pregnancy was independent of risk factors for pregnancy (smoking, p=0.05; alcohol consumption, p=0.66), iron absorption inhibitors in the diet (coffee, p=0.33; tea, p=0.53), water intake (p=0.52) or night eating (p=0.27).
Conclusions: The results of dietary survey showed no direct link between the prevalence of anaemia and nutritional factors. Lower pre-pregnancy BMI was not associated with higher risk of iron deficiency anaemia, and daily iron supplementation during pregnancy did not meet the needs to counteract the anaemic syndrome. Nutrition education is particularly important for the prophylaxis of iron deficiency anaemia in pregnant women.
Objective: The purpose of this retrospective study is to describe clinical, epidemiological and bacteriological findings on the Ear, Nose and Throat infections from patients admitted in a tertiary hospital from Romania, which might bring supportive data for the management of the ENT patients.
Methods: Clinical data from 146 patients admitted in a clinic from Romania, between February 2016 and April 2018 were collected from the official registries of the Microbiology Laboratory, where the collected samples were processed by classical microbiological methods.
Results: From 164 analyzed biological samples, 45.1% were suggestive for infection. Methicillin-sensitive Staphylococcus aureus was the most prevalent bacterial isolate (28.72%), followed by Pseudomonas aeruginosa (12.77%). There were 26 different species of microbes. Out of a total of 77 bacterial isolates, 62.33% were Gram positive and 37.66% Gram negative. The study showed that 11 ear discharge samples were positive in female and male patients. Upper respiratory tract exudates were positive on 3 females (21.4%) and on 17 males (28.8%). There were 7 positive pus samples from females, and from 25 males.
Conclusions: Men were more affected by Ear Nose and Throat infections, caused by bacteria mostly from the genus Staphylococcus and Pseudomonas. More attention at the samples collection and a rigorous clinical examination should reduce the load on bacteriology laboratory. In specific cases, a negative bacteriological result can prove as an exclusion diagnostic.
