This study aimed to evaluate the combined influence of cyclic loading, abutment angulation, and implant diameter on screw torque loss in dental implants. Material and Methods: A total of 80 bone-level implants, divided into standard and narrow diameters, underwent cyclic loading protocols. These implants were paired with straight and 15-degree angled abutments. The study assessed the reverse torque values (RTV) before and after loading, with a primary focus on the effects of cyclic loading, abutment angulation, and implant diameter on screw torque loss. Results: Cyclic loading protocols and screw diameter significantly influenced screw torque loss. Standard diameter implants exhibited higher RTV compared to narrow diameter implants. . While the role of abutment angulation was less definitive, narrow diameter implants with angled placements showed a pronounced decrease in RTV. The study also highlighted that even with optimal preload values, a percentage of the initial preload is lost, potentially leading to screw loosening Conclusion: Cyclic loading and screw diameter are pivotal determinants of screw torque loss in dental implants. The study underscores the need for careful consideration of implant diameter and abutment angulation, especially in narrow diameter implants with angled abutments, to ensure optimal implant stability.","PeriodicalId":18486,"journal":{"name":"Medical Science and Discovery","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136105772","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we have shaped the characteristic features of the tumor according to the 2010 classification rating of The World Health Organization (WHO) (surgical margin, invasion, grading, TNM stages) and also explored the disease-free survival in these patients. Material and Methods: This is the medical record of the patient with 7266 appendectomy retrospectively evaluated, and with these examples in histopathological analysis, a total of 43 patients were diagnosed with appendicitis NETs and included in the study. Age, gender, prediction of the surgical team during the operation, location of the tumor, WHO grade, depth of invasion, positive surgical margin, tumor size, TNM stage, and postoperative survival of these patients were analyzed retrospectively. Results: In this study, the incidence of appendiceal (NETs) was found to be 0.59% among 7,266 patients. Out of the 42 patients with appendiceal NETs, 27 were female and 16 were male. The mean age of the patients was 33.65 years (range: 11–78). The diagnosis was aided by clinical examination, ultrasound, and abdominal computerized tomography (CT) imaging. Most patients were initially diagnosed with appendicitis, and surgical interventions, including laparoscopic and conventional appendectomy, were performed. The pathological analysis confirmed appendicitis with NETs, classified according to the WHO 2010 recommendation. The majority of patients had well-differentiated NETs (G1 or G2). Surgical resection achieved negative radial margins, and no pathological signs were detected during follow-up colonoscopies. At a median follow-up of 70.2 months, all patients remained disease-free and alive. Conclusion: Appendiceal neuroendocrine tumors are rare but distinct entities that require a multidisciplinary approach for diagnosis and management. Surgical resection is the primary treatment, with systemic therapies reserved for advanced cases. The prognosis is generally favorable, with better outcomes seen in well-differentiated tumors. Long-term follow-up is crucial. Further research is needed to improve understanding and optimize treatment strategies for these tumors.","PeriodicalId":18486,"journal":{"name":"Medical Science and Discovery","volume":"101 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136019153","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thromboprophylaxis is commonly employed in the management of most cancer patients, with the most common side effect being bleeding. It is not uncommon for patients to experience a recurrence of VTE during their treatment, highlighting a notable gap in the available evidence on this issue. Case: A 67-year-old male patient, actively undergoing chemotherapy for lung adenocarcinoma and initiated on low molecular weight heparin (LMWH) due to the development of PE, presented to the emergency department with DVT as a consequence of irregular use of anticoagulant injections. The patient, after being re-administered heparin, subsequently presented with intracranial hemorrhage on the 5th day post-discharge, ultimately leading to a fatal outcome. Conclusion: Both cancer patients and the elderly are at a heightened risk of experiencing VTE recurrence. The initiation of anticoagulation treatment elevates the risk of bleeding, particularly within the first ten days. Despite the frequent presentation of VTE recurrence in cancer patients at emergency departments, it remains underreported.","PeriodicalId":18486,"journal":{"name":"Medical Science and Discovery","volume":"131 S2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136104934","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Panniculitis is an uncommon cutaneous manifestation of Sjögren's syndrome (SS), an autoimmune disease primarily known for causing dry eyes and mouth. Case: We report the case of a 56-year-old female initially diagnosed with rheumatoid arthritis, who later met the 2016 ACR-EULAR criteria for primary Sjögren’s syndrome. Following several treatments, she developed nodular lesions in the interscapular area, which were later diagnosed as septal panniculitis associated with SS. Panniculitis can sometimes precede the formal diagnosis of systemic diseases, such as SS. Therefore, it is essential to consider conditions like Sjögren syndrome in the differential diagnosis of unexplained panniculitis. Conclusion: This case underscores the potential link between Sjögren's syndrome and panniculitis. Panniculitis may manifest before the formal diagnosis of Sjögren's syndrome.

The objective is to identify patterns in mortality rates, investigate regional prevalence, and analyze demographic factors contributing to fatal outcomes. Additionally, we aim to critique existing data collection methodologies. Materials and Methods: Utilizing cross-sectional analysis, data were obtained from the Turkish Statistical Institute (TUIK). Mortality rates were calculated using population estimates from the TUIK, with age- and sex-specific rates, and age-standardized rates (ASRs) derived from the world standard population. Causes of death were classified according to the World Health Organization's International Classification of Diseases, Tenth Revision (ICD-10). Results: The data revealed distinct patterns in mortality rates for CNS and PNS disorders from 2018 to 2022, with significant variations between male and female populations. A prominent upward trend in deaths attributed to CNS and PNS diseases was observed after 2018, despite a decline in the population growth rate. The highest mortality rates were particularly notable in 2020 and 2021. Conclusion: This study identified a significant increase in deaths related to CNS and PNS disorders amid the backdrop of the COVID-19 pandemic. A potential correlation between COVID-19 and the prevalence of neurological disorders has been suggested. With potential underdiagnosis due to the absence of routine post-mortem diagnostic autopsies, this study underscores the need for improved diagnostic capabilities and medical practices.","PeriodicalId":18486,"journal":{"name":"Medical Science and Discovery","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136019296","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Congenital Cutis Laxa (CCL) is a rare disease characterized by loss of skin flexibility and laxity, and atypical facial appearance.
 Case Presentation: A 1290-gram female baby at 30+6 weeks of gestation was hospitalized due to premature birth and respiratory distress. During physical examination, an atypical facial appearance, wrinkles on the forehead, skin laxity, and philtrum were visible as well as a small chin and arachnodactyly in the fingers and toes. The patient displayed metabolic alkalosis in her blood gases. The patient, with an atypical face and current findings submitted her exome for genetic diagnosis. Genetic analysis revealed the presence of homozygous NM_001184832.2:c.2485+5G>A (rs749269268) in SLC12A1, and NBS Type 1 was diagnosed. A novel heterozygous NM_000501.4:c.352G>T, p.Val118Phe (rs781922544) variant was detected in ELN, and CCL syndrome with autosomal dominant inheritance was diagnosed.

This study aimed to assess the cynicism and burnout syndrome levels among hospital nurses. Material and Methods: The study employed a descriptive design and involved the administration of standardized scales and a questionnaire to voluntary participants, who were nurses at a designated tertiary hospital. The questionnaire, conducted through face-to-face interviews, aimed to collect socio-demographic information, address specific concerns relevant to nurses, and comprehensively evaluate their levels of cynicism and Burnout, thereby capturing crucial socio-demographic details. Results: A total of 327 nurses participated in the study. Findings indicated that 58.1% of the nurses had willingly chosen their profession, 48.6% expressed satisfaction with their profession, and 22.3% believed their profession was valued. The study revealed a positive correlation between sub-dimensions of the burnout scale, sub-dimensions of the organizational cynicism scale, total organizational cynicism scale scores, and general cynicism scale scores (p < 0.05). Conclusion: These results indicate that nurses are at risk of experiencing cynicism and burnout syndrome. It is, therefore, crucial to identify risk factors and implement preventive measures early on to minimize the risk.

The aim of our study is to explore the relationship between the number of MES and the extent of carotid stenosis as well as plaque morphology. Our goal is to provide a fresh perspective on the treatment of carotid stenosis. Materials and Methods: A total of 95 patients, who were admitted to the emergency department of Sultan 2.Abdülhamid Han Training and Research Hospital and were hospitalized with a diagnosis of stroke, were enrolled in the study. Patients with high-risk cardiac diseases were excluded from the study. Detailed medical histories, risk factors, and current medical treatments of the patients were documented, and microemboli detection was conducted using Transcranial Doppler (TCD). The number of microemboli in TCD was obtained by averaging the results of 2 consecutive half-hour follow-ups in a region. Carotid stenosis rates of the patients were determined by computed tomography angiography (CTA) according to the North American Symptomatic Endarterectomy Trial (NASCET) classification, and the plaque morphology was determined according to the Gray-Weale scale of carotid ultrasonography. Patients were categorized into symptomatic and asymptomatic carotid stenosis groups, and the number of microembolic signals (MES) was compared between these groups. Result: MES numbers of 95 patients with symptomatic carotid stenosis; while MES was not detected in 47.4% (n=45); 35.8% (n=34) had 1-2 MES, 8.4% (n=8) had 3-4 MES and 8.4% (n=8) 5 or more MES were detected. The relationship between the MES obtained and carotid stenosis was statistically significant (p<0.001). According to the type of plaque; while there is no MES in 68.2% (n=15) of Type-4 symptomatic stenosis, this rate is only 15% (n=3) in Type-1 stenosis. In addition, 20% (n=4) of Type-1 symptomatic stenosis had MES between 3-4 and 30% (n=6) of 5 or more MES. According to these results, the relationship between plaque type and the presence of MES is statistically significant. (p<0.001) Similar results were obtained in asymptomatic carotid stenosis. Conclusion: TCD is an easy-to-apply, non-invasive imaging technique, and MES detectable by TCD are risk factors for stroke.

This study aimed to assess the effects of different file systems on postoperative pain in root canal treatments performed on primary molar teeth. Material and Methods: The study included 100 patients aged 5-8 years. NiTi K-type hand files (NTK), rotary file systems ProTaper Next (PTN), AF Baby (AFB), EndoArt Niti Pedo Gold (EAN), and reciprocal file system WaveOne Gold (WOG) were employed in the canal treatment of mandibular primary molars. Postoperative pain was assessed using the Visual Analog Scale (VAS) at the 6th, 12th, 18th, 24th, 48th, 72nd hour, and 1st week following treatment, and the collected data were evaluated statistically. Results: When considering time as a factor, the postoperative pain values among the groups were compared using the Kruskal-Wallis H test, and no statistically significant differences were observed (p = 0.007). In numerical terms, the group using NTK, EAN, AFB, and PTN exhibited the highest average postoperative pain, while the group using WOG, a reciprocal system, had the lowest pain. Conclusion: In conclusion, the choice of file used impacts postoperative pain. There was no statistically significant difference in time-independent postoperative pain values between rotary files designed for primary teeth and those intended for permanent teeth. However, using files specifically designed for primary teeth is recommended, considering factors such as working comfort and suitability for working length.","PeriodicalId":18486,"journal":{"name":"Medical Science and Discovery","volume":"10 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134907016","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
