Dentigerous cyst (DCs) is the type of odontogenic cyst and is the one of the most common type of cyst occurring in the jaw. Dentigerous cyst is clinically asymptomatic and is found radiographically. It encloses the crown of impacted tooth. Histological evaluation is important in such cases as sometimes radiographically interpretated Dentigerous cyst is diagnosed as Unicystic ameloblastoma, dental follicle or an odontogenic keratocyst. In this case report, 18years old boy is reported with clinical diagnosis of pericoronitis and radiographic finding of Dentigerous cyst which on histopathological investigation revealed features of plexiform ameloblastoma on post-operative excisional biopsy.

Recent research has shown that Kiswahili is faced with lack of full implementation of language policy at various levels yet scholars have argued that language policy performs a substantial role in the enhancement of performance as well as the comprehension of the language. It is based on this thrust that this study was carried out to explore the challenges associated with enforcing school language policy in secondary schools. The study was conducted in 30 out of 300 public secondary schools found in Bungoma County. Stratified, purposive and simple random sampling techniques were used to sample the target groups. The questionnaire and focused group discussion guide and document analysis guide were used to collect data. The data was analyzed using descriptive statistics which included the use of frequencies, percentages and narrations. The study established that the challenges associated with the enforcement of school language policy were dependent on the type of school. In view of the above findings, it was recommended that day sub-county secondary school administrators, both in rural and urban areas should come up with stringent measures in enforcing the school language policies because of the nature of their schools. It is hoped the finding of this study would help MOEST, principals of schools and teachers in formulating school language policy that aim at enhancing students achievements in languages offered in the curriculum.

Maritime piracy and border crimes pose significant threats to Cameroon’s security and regional stability and this justifies why the Gulf of Guinea has emerged as a focal point of global concern in Africa. This tumultuous maritime environment has weathered ongoing challenges over time, necessitating a meticulous examination of its security landscape. The study argues that the ineffectiveness of Cameroon’s maritime security is largely due to weak legal framework, colonialism, inadequate enforcement mechanisms, corruption and lack of regional cooperation. It further highlights the fact that the country’s piracy laws are often ineffective, and enforcement agencies lack the capacity and resources to combat piracy and related crimes. In addition, Cameroon faces significant maritime security challenges in the Gulf of Guinea, including limited resources for maritime patrols, surveillance, and judicial capacity, inadequate ports and coastal infrastructures, corruption and the involvement of organized criminal networks in maritime crimes and the lack of trust between coastal communities and law enforcement agencies. The study that made use of primary and secondary data, reveals that poverty, unemployment, and lack of economic opportunities in coastal communities are the root causes of maritime insecurity, piracy, armed robbery and oil related crimes in the Gulf of Guinea. To address these threats, Gulf of Guinea countries need to strengthen their legal framework to ensure effective prosecution of maritime criminals and to align its laws with international standards and invest in maritime security capacity building, including training for coast guard personnel, intelligence gathering, and judicial personnel. The study makes necessary policy recommendations and concludes that, for peace to return in the Gulf of Guinea, the evolving nature of challenges necessitates continued efforts to address emerging threats in the dynamic maritime security landscape.

Background: Interprofessional rivalry marked by competition, a lack of collaboration, and role conflicts among healthcare professionals has become a major hurdle in health systems, especially in low- and middle-income areas like Abuja, Nigeria. These tensions can really undermine teamwork, the quality of care, and overall health outcomes. Even though there's increasing concern about this issue, we haven't fully explored how such rivalry impacts service delivery and the performance of the health system in Abuja. Objectives: The goal of this systematic review is twofold: first, to gather and synthesize existing evidence on how interprofessional rivalry shows up and what drives it within the health system; and second, to evaluate the effects of this rivalry on health services. Methodology: To do this, we conducted a thorough search across various databases, including PubMed, Scopus, Web of Science, African Journals Online (AJOL), and Google Scholar, looking for both peer-reviewed and grey literature. We included studies that examined interprofessional dynamics in health facilities. Two reviewers independently extracted data and assessed quality using PRISMA guidelines, and we applied thematic synthesis to bring together both qualitative and quantitative findings. Discussion: Our review revealed ongoing rivalry between key professional groups, particularly between doctors and allied health workers. This rivalry is often fueled by perceived inequalities in leadership, pay, and recognition. Such tensions lead to fragmented care, poor communication, high staff turnover, and resistance to collaborative policy efforts. The broader systemic effects include weakened governance, flawed referral systems, and compromised patient safety. Additionally, context-specific issues like weak regulatory oversight and the politicization of professional bodies make the situation even worse. Conclusion: Interprofessional rivalry in the health sector has significant systemic implications that jeopardize the quality, equity, and sustainability of health services. There’s an urgent need for targeted interventions to address these challenges.

Stray dog populations have significant ecological, social and health impacts on both human and wildlife populations. In urban areas, these feral pose challenges such as the spread of zoonotic diseases, aggressive encounters, and competition for resources, affecting public safety and sanitation. In wildlife habitats, stray dogs disrupt the ecosystem by preying on native species, transmitting diseases, and competing with the indigenous predators. Additionally, human activities, including improper waste disposal and habitat encroachment aggravate the issue by providing the feral dogs with sustenance and shelter. Effective management strategies that include sterilization programs, community engagement, and policy interventions, are essential to mitigate the negative consequences while fostering sustainable coexistence. This paper explores the complex interactions between stray dogs, humans and wildlife and outlines effective strategies for balanced management.

This study presents a comparative evaluation of Latent Semantic Analysis (LSA)-based extractive summarization against traditional statistical and neural approaches using cosine similarity as the principal evaluation metric. The methodology involves implementing an LSA summarizer on structured textual data, particularly a speech document, and analysing its performance relative to Naïve Bayes and Rank Net-based models. Key evaluation criteria include precision, recall, F1 score, and semantic similarity between original and summarized texts. Results show that while LSA marginally trails neural models in performance, it significantly outperforms traditional approaches and offers advantages in interpretability, computational efficiency, and adaptability. The study also explores how sentence scoring within the semantic space contributes to summary quality, as well as the effect of summary length on content retention. Visual data representations support these findings and highlight the model’s semantic focus. Recommendations suggest using LSA in low-resource settings or as part of hybrid systems. Future research directions include expanding to multi-document and multilingual summarization, as well as integrating sentence compression. Overall, LSA is reaffirmed as a viable, adaptable, and efficient summarization method suitable for various real-world applications.

Ergonomics is an interdisciplinary field that studies the relationship between people and various systems, aiming to improve human welfare and optimize system efficiency. In dentistry, ergonomics plays a critical role in sustaining clinicians' competence, efficiency, and ability to deliver high-quality treatment throughout their careers. Given the confined working field of the oral cavity, which demands precision within mere millimetres and careful force application, dental professionals are required to maintain static postures that involve prolonged muscle contraction, often engaging nearly 50% of their musculature. This physical strain, if unmanaged, can lead to various musculoskeletal disorders (MSDs), compromising both practitioner health and patient care. This review aims to consolidate current literature on dental ergonomics, risk factors, the development of MSDs and techniques to improve ergonomics.

In order to effectively address the long-standing issue of Chinese Cultural Aphasia among English learners in China, this paper builds a “Three Inclusions” model of the Integrated English Course for undergraduate English majors under the guidance of POA theory. Taking Xi Jinping: The Governance of China as a starting point and POA theory as a guide, the paper redesigns the Integrated English Course across the board to achieve multi-dimensional integrated teaching path that combines concepts, textbooks, strategies, and evaluation. The whole teaching design can make up for the lack of discussion on Chinese culture and social reality in English teaching, strengthening the national conditions awareness of English major students, and enhancing their ability to tell China's stories well and spread China's voice well. Finally, "Equal Opportunity, Our National Myth" written by Joseph Stiglitz is selected for case study to demonstrate the specific implementation path for POA’s three phases of motivating, enabling and assessing.

The purpose of this study was to assess the demographic, clinical, and haematological characteristics of women with hypertensive disorders of pregnancy (HDP) compared to normotensive pregnant individuals during their third trimester. It was a cross-sectional study involving 270 women with HDP and 270 normotensive individuals admitted to the maternity unit at Nelson Mandela Academic Hospital in South Africa. The definition of HDP followed the International Society for the Study of Hypertension in Pregnancy guidelines. Blood pressure was measured using an automated device and blood samples were collected for measurement of haemoglobin, platelet count, creatinine, alanine transaminase (ALT), aspartate transaminase (AST), and lactate dehydrogenase (LDH). The median age was 27 years while the youngest and oldest were 15 years and 46 years respectively. The unemployment rate was higher among women with HDP compared to normotensive individuals (p = 0.017). HIV prevalence showed no significant difference (p > 0.05). Hypertensive cases had higher median pulse rates [87(74-98) vs 82 (IQR:67-95) b/m, p = 0.023] and lower median platelet counts [(230 (IQR:159-281) vs 240 (IQR:192-293) x109/L, p = 0.009). Additionally, hypertensive cases had significantly (p < 0.0001) higher median levels of urea (3 vs 2 mmol/L), creatinine (60 vs 50 umol/L), AST (28 vs 21 u/L), ALT (14 vs 11 u/L), and LDH (383 vs 270 u/L).In conclusion, women with HDP exhibit distinct clinical and haematological differences compared to normotensive controls, highlighting the importance of careful monitoring for patients with HDP to mitigate potential complications.
