Background: Cystic hygromas are primarily found in the cervicofacial, thoracic, and abdominal regions, with limited occurrences in other areas. Despite existing literature on this condition, comprehensive descriptions and MRI findings of cystic hygromas in the extremities are rare. Aim: This case report aims to present a unique instance of a cystic hygroma in the left thigh. The objective is to provide detailed insights into the characteristics of this atypical presentation. Case Presentation: The case involves a 2-year-10 month-old girl with a cystic hygroma in her left thigh. The report includes a comprehensive description of the lesion’s clinical features and diagnostic evaluation, emphasizing the MRI findings to enhance understanding of this rare occurrence. Conclusion: This case report highlights the rarity of cystic hygromas outside the cervicofacial, thoracic, and abdominal regions, explicitly focusing on the occurrence in the left thigh. By presenting detailed insights into the clinical features, MRI findings, histopathological findings, and the surgical approach employed, this report contributes to the existing knowledge on this condition in atypical locations and informs future treatment strategies.

Nipah virus (NiV) is a highly infectious zoonotic pathogen that poses a significant threat to human and animal health. First identified in Malaysia in 1998, NiV has since caused several outbreaks in Southeast Asia, with sporadic cases reported in Bangladesh and India. The virus is primarily transmitted to humans through direct contact with infected animals, primarily fruit bats, or through the consumption of contaminated fruits and their juices. NiV infection presents a wide spectrum of clinical features, ranging from mild respiratory illness to severe encephalitis, with a high case fatality rate. The incubation period typically ranges from 4 to 14 days, during which patients develop fever, headache, myalgia, and respiratory symptoms such as cough and sore throat. As the disease progresses, neurological signs become prominent, including altered consciousness, seizures, and focal deficits. Severe cases may exhibit acute respiratory distress syndrome and multi organ failure. Laboratory findings often include lymphocytopenia, thrombocytopenia, and elevated liver enzymes. Diagnosis of NiV infection requires specialized laboratory testing, including reverse transcription-polymerase chain reaction (RT-PCR) and serological assays. Currently, no specific antiviral treatment exists for NiV infection, and management primarily focuses on supportive care. Prevention and control strategies encompass public health interventions, surveillance, and raising awareness among healthcare providers and the general population. The emergence and re-emergence of NiV highlight the urgent need for continued research, improved diagnostic capabilities, and the development of effective vaccines and therapeutics to mitigate the impact of this deadly virus.

Background: Since the outbreak of the COVID-19 pandemic caused massive case fatalities across the world, people have been left with significant physical and mental disabilities, which has had an adverse impact on their quality of life. The objective of this study is to measure the short-term and long-term outcomes among COVID-19 survivors. Methods: This is a six-month-long multicentre prospective observational study, carried out in four specialized hospitals in the capital city Dhaka, where six hundred participants were enrolled by non-probability convenience sampling. Data were collected through three structured interviews, and follow-ups were done during discharge, at 1st month, and 6th month. An analytical study was done on demographic variables, socio-economic conditions, physical findings and outcomes. Data were analysed using Statistical Package for Social Sciences (SPSS). Results: A total of 600 participants were enrolled. The mean age was 49.83. Many participants belong to the age range of 31 to 40 years. More than two-thirds (72.7%) of participants were male, whereas 27.30% were female. Most patients admitted had mild and moderate COVID-19 symptoms (40% and 58%, respectively). Among short-term COVID complications, it was found that 43.3% of the participants complained of fatigue, 32.6% of depression, 24.7% of sleep disturbance, 19% of anxiety and, 5% memory loss. In long-term COVID complications the number reduced significantly: 5% of the participants complained of fatigue, 10% of depression, 2.7% of sleep disturbance, 7.3% of anxiety and, 2.7% memory loss. The severity of lung parenchymal disease also reduced in long term COVID symptoms. The study found a statistically significant relationship between age groups and CT severity index (χ2 = 9.458, p = 0.032). Most patients (29.2%) in the under-30 age group had a CT Severity Index score of 2 & 3 (29.2%). The important CT Severity Index scores for individuals aged 30 to 60 years were 3 and 4, accounting for 3

随着软件无线电技术在无线网络领域内的应用越来越广,传统的电子战干扰与新兴的无线网络赛博攻击之间的界线更加模糊。为了精确描述快速发展的无线安全领域内的这些新兴概念,文章提出了一种干扰机分类方法,以便对通信干扰机的理论行为和特点进行分类。与传统上根据干扰机所能干扰的信号类型进行分类相比,文章提出根据干扰机所拥有的信息及其利用信息的能力来分类。这些关键的干扰机能力包括干扰机是否具备时间相关性、协议感知能力、欺骗能力、学习能力。这些能力又可根据干扰机特性进行二级细分,包括干扰机的各种参数,如相对带宽、占空因数、调制方式、天线方向图以及该天线方向是否可控。最后,对当前相关文献中提出的干扰方法进行了抽样研究,并讨论如何将其归入本文提出的分类体系中。
