Introduction: Technological advances have greatly influenced the healthcare sector. The ability to transmit information and deliver services using telecommunication tools continues to transform the way healthcare is delivered around the world. The aim of this study was to highlight the epidemiological, clinical and therapeutic profile of oral and maxillofacial surgery patients consulted using the WhatsApp application. Methodology: This was a three-year descriptive study with a retrospective data collection, from 2021 to 2023, of WhatsApp communications between our team and oral and maxillofacial surgeons in Cameroon. In this study, the type/content of messages received, the epidemiological data of practitioners and patients, the various pathologies diagnosed and the procedures performed were evaluated. Results: 319 communications were received for a total of 146 cases. Written messages associated with images (photographs and/or X-rays) were the most frequently received, at 85.62%. Hospitals in urban areas were the most represented at 93.84%. Oral health professionals in the private sector sent more messages (65.75%). In terms of diagnoses, tumour and cystic pathologies were the most common (28.08%), followed by impacted/retained teeth (22.6%). Patients were referred to our hospital for treatment in 62.33% of cases. Conclusion: The WhatsApp application is an easy-to-use telecommunications tool. It facilitates exchanges between practitioners and improves patient care in oral and maxillofacial surgery.

Background: Ectopic pregnancy is a major cause of maternal morbidity and mortality, estimated to occur in 1% - 2% of pregnancies worldwide. This condition also has an adverse effect on the fertility prospects of women who experience it. Objective: To determine the outcomes of subsequent spontaneous fertility after medical treatment of patients with methotrexate (MTX) in patients with ectopic pregnancy at two university teaching hospitals of Yaounde. Methodology: We carried out a cross-sectional study with retrospective data collection in two university teaching hospitals of Yaounde during a six years period from 1st January 2015 to 31st May 2021. Seventy records of patients who had medical treatment for ectopic pregnancy were included in this study. Statistical analysis was performed using SPSS. 23. The Chi-2 statistical test was used to compare qualitative variables. Binary logistic regression method was performed to identify independent risk factors associated with infertility after medical treatment of tubal ectopic pregnancy (TEP). The significance level was set at 0.05. Results: The mean age in our study population was 27.8 ± 3.8 years. According to the past medical history, 52.9% had a pelvic inflammatory disease (PID) and the most frequently germ found was C. trachomatis (47.1%). Almost 15% of our study population had previous surgery for EP. The median Fernandez score was 11 with a minimum score of 4 and a maximum score of 13. The route of administration of methotrexate was intramuscular in all our patients, and the single-dose protocol was used most frequently (58.6%). After medical treatment of the EP, we found a spontaneous conception rate of 58.6%. After multivariate analysis, we were unable to confirm that there was an association between a history of sexually transmitted infections (STIs) and fertility prognosis. Conclusion: The spontaneous fertility rate after medical management of EP was 58.6%, of which 73.2% were term pregnanci

本文重新解读了中古英语文学作品中手稿变体对句法和意义产生的效果。论文借用“事后性”(弗洛伊德称之为“延迟性”)这一心理分析概念,以《巴斯妇人的开场语》为个案,将变体视为一个双向时间结构。伯纳德·塞尔奎利尼在《对变体的赞美》(1989)中将变体描述为一种产生新句法结构的活动。异文追溯、重构了它嵌入其中的话语的句法。异文不是嵌入固定句法结构的替代词汇选择;它们应被视为动态组合,当它们在话语中出现时,会改变每个话语的结构,往前往后都起作用。因此,意义永远不会准时到达,而是总会延迟。

Comparative Study of Neurosurgical Complications of Thalassemia and Sickle Cell Disease

引用

Open Journal of Modern Neurosurgery 2024年第3期14卷 190-202页

Introduction: Sickle cell disease and thalassemia are the most frequent hemoglobinopathies. During their evolution, they present certain complications, among which are two neurosurgical emergencies, namely spontaneous cranial epidural hematoma and non traumatic radiculo-medullary compression, with some particularities for each. Method: In order to highlight these particularities, we compared the characteristics of these two complications, from a number of publications reported between 2000 and 2021. Results: Sickle cell disease was complicated by spontaneous cranial epidural hematoma. Forty-two cases were reported, the mean age was 14.7 years (2 - 21 years) and the sex ratio was 6.4. The clinical presentation combined, in a non-traumatic context, signs of intracranial hypertension with those of neurological focalization. Neuroimaging showed epidural-type collection, often frontal and parietal in location. The incriminating mechanisms were ischemia, hemorrhage and extra medullary hematopoiesis. The treatment was surgical. Non traumatic radiculo-medullary was the complication of thalassemia. Of the 77 cases reported, the mean age was 27.5 years (9 - 66 years) and the sex ratio was 4.1. The lesions were epidural with a clear thoracic predominance and resulted from extra marrow hematopoiesis. Treatment included: hypertransfusion, radiotherapy, hydroxyurea and surgery. Vital and functional prognosis were globally satisfactory when the management was rapid. Conclusion: Cranial and spinal epidural lesions, respective complications of sickle cell disease and thalassemia, result from similar mechanisms. Their prognosis depends on the rapidity of management. .

Synchronous waving in fiddler crabs: a review

引用

Current Zoology 2019年第1期65卷 83-88页

作者： Patricia ruth Yvonne Backwell Research School of Biology The Australian National University Canberra ACT 2601 Australia

Many animals that use acoustic communication synchronize their mate attract!on signals: individuals precisely time their calls to overlap those of their neighbors. In contrast, synchrony in the mate attraction displays of species with visual/motion-based signals is rare. It has only been documented in five species of fiddler crabs. In all of them, small groups of males wave their single large claw in close synchrony. Here, I review what we know about synchrony in fiddler crabs, comparing the five species with each other to determine whether similar mechanisms and functions are comm on to all. I also propose future research questions that, if answered, would shed light on synchronous behavior in both visual and acoustic signallers.
