Comparison of digital and conventional impression techniques: evaluation of patients’ perception, treatment comfort, effectiveness and clinical outcomes

Background: The purpose of this study was to compare two impression techniques from the perspective of patient preferences and treatment comfort.Methods: Twenty-four (12 male, 12 female) subjects who had no previous experience with either conventional or digital impression participated in this study. Conventional impressions of maxillary and mandibular dental arches were taken with a polyether impression material (Impregum, 3 M ESPE), and bite registrations were made with polysiloxane bite registration material (Futar D, Kettenbach). Two weeks later, digital impressions and bite scans were performed using an intra-oral scanner (CEREC Omnicam, Sirona). Immediately after the impressions were made, the subjects' attitudes, preferences and perceptions towards impression techniques were evaluated using a standardized questionnaire. The perceived source of stress was evaluated using the State-Trait Anxiety Scale. Processing steps of the impression techniques (tray selection, working time etc.) were recorded in seconds. Statistical analyses were performed with the Wilcoxon Rank test, and p < 0.05 was considered significant.Results: There were significant differences among the groups (p < 0.05) in terms of total working time and processing steps. Patients stated that digital impressions were more comfortable than conventional techniques.Conclusions: Digital impressions resulted in a more time-efficient technique than conventional impressions. Patients preferred the digital impression technique rather than conventional techniques

The study aims to measure depression, anxiety, and QoL prevalence among Jordanian patients with End Stage Renal Disease (ESRD) on hemodialysis and how all of these variables are correlated.Methods: This is a cross-sectional, interview-based study on patients at the Jordan University Hospital (JUH) dialysis unit. Sociodemographic factors were collected, and the prevalence of depression, anxiety disorder, and QOL was assessed using the Patient Health Questionnaire 9 (PHQ9), the Generalized Anxiety Disorder 7-item (GAD7), and the WHOQOL-BREF, respectively.Results: In a study of 66 patients, 92.4% had depression, and 83.3% had generalised anxiety disorder. Females had significantly higher depression scores than males (mean = 6.2 ± 3.77 vs 2.9 ± 2.8, p < 0.001), and single patients had significantly higher anxiety scores than married patients (mean = 6.1 ± 6 vs 2.9 ± 3.5, p = 0.03). Age was positively correlated with depression scores (rs= 0.269, p = 0.03), and QOL domains showed an indirect correlation with GAD7 and PHQ9 scores. Males had higher physical functioning scores than females (mean = 64.82 vs 58.87, p = 0.016), and patients who studied in universities had higher physical functioning scores than those with only school education (mean of College/University = 78.81 vs mean of School Education = 66.46, p = 0.046). Patients taking < 5 medications had higher scores in the environmental domain (p = 0.025).Conclusion: The high prevalence of depression, GAD, and low QOL in ESRD patients on dialysis highlights the need for caregivers to provide psychological support and counselling for these patients and their families. This can promote psychological health and prevent the onset of psychological disorders.Keywords: chronic kidney disease, end stage kidney disease, hemodialysis, quality of life, depression, generalized anxiety disorde

Mediastinal lymphoma-induced superior vena cava syndrome and chylopericardium in a pregnant lady: a case report

Mediastinal malignancies are a commonly identified etiology in superior vena cava syndrome (SVCS), and despite the known management of chemotherapy, radiotherapy, or a combination of both, this can prove to be a dilemma during pregnancy. Reported cases of SVCS management during pregnancy are scarce. Chylopericardium is a rare entity with a myriad of causes, the most common of which is a primary idiopathic origin. Initial management depends on the presence or absence of cardiac tamponade. Long-term therapy is a matter of serious debate, with some opting for conservative treatment, and others favoring a more invasive surgical approach. Cases reporting the occurrence of chylopericardium in association with pregnancy are also limited. In this report, we discuss the case of a 28-year-old pregnant woman who had both SVCS and chylopericardium as a result of a mediastinal lymphoma

Esophageal 99mTc-pertechnetate uptake mimicking an autonomous thyroid adenoma in a patient with subacute thyroiditis: a case report

Subacute thyroiditis (SAT) is one of the most common causes of thyrotoxicosis. Thyroid scans with radioiodine or technetium-99m pertechnetate (99mTc) are often performed in the workup of patients with thyrotoxicosis, particularly to differentiate between SAT and Graves’s disease. Although very helpful, thyroid scans are prone to pitfalls that may occasionally lead to misdiagnosis. These pitfalls are largely related to physiologic uptake of radioiodine or 99mTc in non-thyroidal tissue, such as salivary gland and stomach that may result in false-positive findings. We present herein a very rare case of SAT misdiagnosed as an autonomous thyroid adenoma most likely due to focal 99mTc uptake in the esophagus. This case may have implications for the management of patients with suspected SAT, who undergo a radioiodine or 99mTc thyroid scan

MTHFR gene polymorphisms in hypothyroidism and hyperthyroidism among Jordanian females

ABSTRACT Objective Methylenetetrahydrofolate reductase (MTHFR) is involved in DNA methylation that is associated with autoimmune pathology. We investigated the association between MTHFR genetic polymorphisms at g.677C>T and g.1298A>C and their haplotypes, and the risk of thyroid dysfunction among Jordanian females. Subjects and methods A case-control study involving 98 hypothyroidism cases, 66 hyperthyroidism cases and 100 controls was conducted. Polymerase chain reaction/restriction fragment length polymorphism technique was performed to determine genotypes. Statistical analysis using SPSS software was performed. Results Genetic analysis showed a significant difference in genotype frequency of g.1298A>C between cases, and controls [hypothyroidism: AA (45.9%), AC (37.8%), CC (16.3%); hyperthyroidism: AA (9.1%), AC (69.7%), CC (21.2%); controls: AA (37.8%), AC (29.6%), CC (32.7%); CChypo vs. AAhypo: 2.55, 95% CI: (1.18-5.52); OR at least on Chypo: 1.79, 95% CI: (1.07-2.99)]; CChyper vs. AAhyper: 4.01, 95% CI: (1.79-9.01); OR at least on Chyper: 0.18, 95% CI: (0.07-0.48)]. There was no significant difference in genotype frequency of g.677C>T between cases and controls [hypothyroidism: CC (50.0%), CT (32.7%), TT (17.3%); hyperthyroidism: CC (77.3%), CT (15.2%), TT (7.6%); controls: CC (55.6%), CT (32.3%), TT (12.1%)]. There was a significant difference of MTHFR haplotypes among hypothyroidism cases and controls. TA and CC had a lower hypothyroidism risk whereas; TC showed a higher risk. Conclusions g.1298A>C genetic polymorphism of MTHFR may modulate the risk of thyroid disease. CC, TA, and TC haplotypes affect the risk of hypothyroidism. Larger samples should be included in the future to verify the role of MTHFR polymorphisms in thyroid diseases

Hematologic markers of distant metastases and poor prognosis in gynecological cancers

Abstract Background Despite the recent progress in the development of anti-cancer drugs, the treatment of metastatic tumors is usually ineffective. The systemic inflammatory response performs key roles in different stages of the carcinogenesis process including metastasis. The high neutrophil-lymphocyte ratio (NLR), monocyte-lymphocyte ratio (MLR), and platelet-lymphocyte ratio (PLR) were found to be associated with poor survival rates in the majority of solid tumors. However, only a few studies were conducted to further investigate this association in patients with advanced gynecological cancers. Methods Clinical data from 264 patients with FIGO stage III and IV gynecological (endometrial, ovarian and cervical) cancers treated at King Hussein Cancer Center (Amman-Jordan) from 2006 to 2012 were retrospectively reviewed. We examined the association between absolute neutrophil count (ANC), absolute monocyte count (AMC), MLR, PLR, and NLR with distant metastases, overall survival and event-free survival in gynecological cancers. For survival analysis, Receiver Operating Characteristic (ROC) curve analysis was operated to determine the optimal cutoff values. Results Patients with high baseline NLR (≥4.1) had more baseline distant metastases than patients with low baseline NLR (< 4.1), (p-value 0.045). Patients with high baseline AMC (≥560) had more distant metastases in comparison to patients with low baseline AMC (< 560), (p-value 0.040). Furthermore, Patients with high baseline PLR (≥0.3) had more distant metastases in comparison to patients with low baseline PLR (< 0.3), (p-value 0.025). Additionally, patients with high baseline ANC (≥5700) had worse overall survival compared to the patients with low baseline ANC (< 5700), (p-value 0.015). Also, patients with high baseline AMC (≥490) had worse overall survival compared to the patients with low baseline AMC (< 490), (p-value 0.044). Conclusion Different hematologic markers obtained from a cheap test (CBC) could potentially be used to predict the presence of distant metastases thus used as prognostic indices in gynecological cancers
