OBJECTIVE: The aim of the study was to review all the cases of ameloblastoma seen at the Oral and Maxillofacial Surgery Clinic of the Lagos University Teaching Hospital, Nigeria, between 1980 and 2003. METHODS AND MATERIALS: In this retrospective study, case files and biopsy reports of new cases of ameloblastoma covering a 24-year period were retrieved and analyzed for sex, age on presentation, histologic type, and site distribution. RESULTS: A total of 207 cases of ameloblastoma were seen in the given period. One hundred and ninety-eight (95.7%) were benign, and 9 (4.3%) were malignant. A male-to-female ratio of 1.1:1 was found. The average ages on presentation for ameloblastoma and ameloblastic carcinoma were 31.67 and 46.44 years, respectively. The lesion was found to be more common in the premolar-molar region of the mandible. The most common histologic type was follicular ameloblastoma (25.1%). Nine (4.3%) cases of ameloblastic carcinoma were also reported. CONCLUSIONS: Ameloblastoma with a predilection for the posterior mandibular region is relatively common in our environment. Sex and site distributions are similar to previous reports in the literature. 相似文献

Acetaminophen (APAP) hepatotoxicity is the most frequent cause of acute liver failure in the US. The mechanisms of APAP-induced liver injury have been under extensive investigations for decades, and many key events of this necrotic cell death are known today. Initially, two opposing hypotheses for cell death were proposed: reactive metabolite and protein adduct formation versus reactive oxygen and lipid peroxidation (LPO). In the end, both mechanisms were reconciled, and it is now generally accepted that the toxicity starts with formation of reactive metabolites that, after glutathione depletion, bind to cellular proteins, especially on mitochondria. This results in a mitochondrial oxidant stress, which requires amplification through a mitogen-activated protein kinase cascade, leading ultimately to enough reactive oxygen and peroxynitrite formation to trigger the mitochondrial membrane permeability transition and cell death. However, the earlier rejected LPO hypothesis seems to make a comeback recently under a different name: ferroptosis. Therefore, the objective of this review was to critically evaluate the available information about intracellular signaling mechanisms of APAP-induced cell death and those of ferroptosis. Under pathophysiologically relevant conditions, there is no evidence for quantitatively enough LPO to cause cell death, and thus APAP hepatotoxicity is not caused by ferroptosis. However, the role of mitochondria-localized minor LPO remains to be further investigated.Key words: Acetaminophen hepatotoxicity, Oncotic necrosis, Apoptosis, Ferroptosis, Lipid peroxidation, Fenton reaction, Glutathione peroxidase 4 相似文献

The influence of social support, work overload, and parity on psychological well‐being of pregnant career women was investigated. Women executives (N200) attending antenatal clinics were selected. A 2 × 2 × 2 analysis of variance (ANOVA) revealed significant independent influence of social support (F(1, 199) = 26.51, p < 0.05) and work overload (F(1, 199) = 461.76, p < 0.05), and significant joint effect of social support and work overload. There was no significant effect of parity (F(1, 199) = 0.72, p > 0.05). Combinations of parity, social support, and work overload were also not significant (F(1, 199) = 0.80, p > 0.05). Social support and appropriate work incentives are helpful in assisting pregnant women executives in coping with psychological changes during pregnancy. 相似文献

The COVID‐19 pandemic continues to be a major public health threat globally and low‐ and middle‐income countries (LMICs) are not an exception. The impact of the COVID‐19 pandemic is far‐reaching on many areas including but not limited to global health security, economic and healthcare delivery with a potential impact on access to healthcare in LMICs. We evaluate the impact of the COVID‐19 pandemic on access to healthcare in LMICs, as well as plausible strategies that can be put in place to ensure that the delivery of healthcare is not halted. In order to mitigate the devastating effect of the COVID‐19 pandemic on the already weak health systems in LMICs, it is much necessary to reinforce and scale up interventions and proactive measures that will ensure that access to healthcare is not disrupted even in course of the pandemic. 相似文献

Existing studies have established several individual drivers of health facility delivery in many developing countries. However, the community characteristics that drive health facility delivery have been less studied across developing countries. This study thus examines the extent to which community characteristics drives health facility delivery among women who had recent live births in Nigeria based on data from the 2018 Nigeria Demographic and Health Survey (NDHS). A weighted sample size of 7,342 women was analysed. The outcome variable was health facility delivery. The explanatory variables were selected individual and community characteristics. Results show 39.7% prevalence of health facility delivery among the women. Findings further reveals that the community characteristics have significant effects on the variations in health facility delivery across the communities. Community characteristics significantly drive health facility delivery in Nigeria. More community-based priority actions are required to improve demand for health facility delivery in the country. 相似文献

BackgroundEpstein-Barr virus (EBV) is a member of the herpesvirus family that is known to ubiquitously infect people worldwide. However, the actual prevalence of EBV infection in diseased patients in Nigeria, remains unknown. This study was thus conducted to ascertain the true prevalence.MethodsA systematic review and meta-analysis of published data was conducted according to the guidelines of Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA). Electronic databases including PubMed, Scopus, ScienceDirect, and Google Scholar were searched for studies reporting the occurrence of EBV infection among patients with established diseases. Studies were included if they assessed EBV infection in diseased patients in Nigeria. Data were extracted and subsequently analysed using R software. Funnel plot and Egger's regression test was used to assess publication bias, while JBI prevalence tool was used to assess study quality.ResultsA total of 13 studies covering 228 cases of EBV infection among 1157 diseased patients were included. Summary estimates were computed using random-effects model. The pooled prevalence of EBV infection was 20.3% (95% CI: 10.8–34.9, I2 ?= ?92.26, p ?< ?0.001). When stratified according to the type of disease, higher estimates were obtained for patients suffering from Kaposi's sarcoma (98.7%, 95% CI: 82.2–99.9) and Nasopharyngeal malignancy (85.7%, 95% CI: 70.0–93.9). A prevalence of 13.4% (95% CI: 6.0–27.4) and 12.2% (95% CI: 4.8–27.8) was derived for the most reported patient populations, lymphoma and HIV, respectively.ConclusionThis first meta-analysis on the prevalence of EBV among Nigerian patients suffering from various diseases reveals a prevalence that emphasises the need to routinely monitor EBV infection in all EBV-associated diseases in Nigeria. 相似文献

Aim
To determine the association of carotid atherosclerosis and right ventricular diastolic dysfunction (DD) among treated hypertensive Nigerian patients.Methods
This was a single center cross-sectional study performed at the Cardiology Clinic of LAUTECH Teaching Hospital, Ogbomoso, Nigeria between January and December 2012. The study included 122 hypertensive Nigerians (mean age, 57.3 ± 14.7 years, 36.9% women). Patients’ clinical, demographic, and echocardiographic parameters were obtained. Diastolic dysfunction was assessed with the trans-tricuspid Doppler flow.Results
Patients with DD were significantly older than those with normal diastolic function. Mean and maximum carotid intima media thickness measurements were significantly higher among patients with right ventricular DD than in those with normal diastolic function. Mean systolic blood pressure (148.3 ± 31.9 vs 128.0 ± 2.8 mm Hg, P = 0.049) and interventricular septal thickness in diastole (12.8 ± 2.3 vs 11.6 ± 2.8mm, P = 0.048) were significantly higher and tricuspid annular pulmonary systolic excursion (33.6 ± 4.9 vs 23.0 ± 4.2 mm, P = 0.035) was significantly lower in patients with right ventricular DD than in those with normal diastolic function. Carotid intima media thickness measurements were correlated with early trans-tricuspid Doppler flow and early transtricuspid diastolic flow/late right atrial transtricupsid diastolic flow ratio.Conclusion
Right ventricular DD in hypertensive patients was significantly correlated with increased carotid atherosclerosis. Carotid intima media thickness measurements may therefore be a surrogate marker for DD in hypertensive subjects.Systemic hypertension has been shown to be associated with right ventricular abnormalities in both morphology and function. Right ventricular diastolic dysfunction (DD) may be an early indicator of hypertensive heart disease accompanying left ventricular DD (1-3). It can be diagnosed by various means including the ratio of early and late trans-tricuspid Doppler inflow velocities and tissue Doppler velocities.Atherosclerosis is the underlying factor for many cases of cardiovascular morbidity and mortality (4). A useful surrogate marker for carotid atherosclerosis is carotid intima media thickness (5). This parameter reflects the severity of thickening/atherosclerosis of the major arteries and is directly linked with the severity of hypertension and target organ damage associated with hypertension (2,4). DD is a typical part of the cardiovascular risk spectrum with increased risk for accelerating progressive cardiac dysfunction (6). However, it is still not known whether carotid intima media thickness, which has been shown to correlate with many conventional cardiovascular risk factors, is associated with right ventricular DD, especially among Africans (7). This study aims to determine the association between right ventricular DD and carotid intima media thickness in a sample of Nigerian hypertensive patients. 相似文献10.

Tropical pyomyositis (TP) is a life‐threatening bacterial infection of the skeletal muscle that occurs particularly among children, young adults and those with immunocompromised conditions. The appropriate diagnosis and treatment are often delayed due to its non‐specific signs, leading to fatal consequences. Staphylococcus aureus, especially methicillin‐susceptible S. aureus, is responsible for most TP cases. However, other bacteria (i.e. streptococci, Pseudomonas aeruginosa, Escherichia coli, Klebsiella spp., Candida spp., Mycobacterium spp.) have been reported. This narrative review provides an update on the epidemiology and clinical course of TP. A special focus is laid on the role of toxins (i.e. Panton‐Valentine Leucocidin and α‐toxin) in the pathogenesis of TP and their implication for the clinical management of infection. 相似文献
