    This paper will focus on electroencephalogram (EEG) signal analysis with an emphasis on common feature extraction techniques mentioned in the research literature, as well as a variety of applications that this can be applied to. In this review, we cover single and multi-dimensional EEG signal processing and feature extraction techniques in the time domain, frequency domain, decomposition domain, time-frequency domain, and spatial domain. We also provide pseudocode for the methods discussed so that they can be replicated by practitioners and researchers in their specific areas of biomedical work. Furthermore, we discuss artificial intelligence applications such as assistive technology, neurological disease classification, brain-computer interface systems, as well as their machine learning integration counterparts, to complete the overall pipeline design for EEG signal analysis. Finally, we discuss future work that can be innovated in the feature extraction domain for EEG signal analysis

    Introduction: The Coronavirus Disease-2019 (COVID19), caused by the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), is a global public health crisis. Pregnant women are known to be disproportionately affected by respiratory illnesses, which are associated with increased infectious morbidity and high maternal mortality rates. Aim: To study the management of COVID-19 in pregnancy and its perinatal outcome. Materials and Methods: This prospective observational study was conducted in the Obstetrics and Gynaecology Department from March 2020 to September 2020. To evaluate the effects of COVID-19 in pregnancy and to determine the maternal and fetal outcomes in COVID-19 positive patients. In order to evaluate the pattern of caesarean and vaginal deliveries in COVID-19 and non COVID-19 patients, chisquare test was done. Results: A total of 150 COVID-19 positive patients were admitted to the COVID-19 labour room and out of them 142 (94.67%) were antenatal and 8 (5.33%) were postnatal. Total number of the deliveries in this period was 80 (53.33%) and out of them vaginal deliveries were 35 (23.33%) and caesarean section were 45 (30%). A 6 (7.50%) babies with poor Appearance, Pulse, Grimace, Activity, Respiration (APGAR) score were admitted to the Neonatal Intensive Care Unit (NICU) and 70 (87.50%) had good APGAR after delivery, four had Intrauterine Death (IUD). Conclusion: The pregnant women with suspected COVID-19 who need medical care should be transferred to a hospital equipped with sufficient health facilities and fully trained clinicians to take proper care of critically ill obstetric patients for effective management

    X-linked ichthyosis along with epidermolysis bullosa

    Ichthyoses are a heterogenous group of hereditary keratinization disorders that share in common the accumulation & shedding of large amounts of hyperkeratotic epidermis. Early reports of ichthyosis in the Indian and Chinese literature date back to several hundred years. X-linked recessive ichthyosis (XLI) is a common disorder of keratinization and affects males who inherit an X-chromosome having a steroid sulphatase genetic mutation. In the present communication we report a case of XLI and dystrophic epidermolysis bullosa in the same patient. To the best of our knowledge it has been reported only once before

    Oral cavity and leprosy

    Although leprosy involves the oral cavity in up to 60% of the patients, examination of the oral cavity in leprosy clinics or oral health science clinics is often neglected. Oral involvement in leprosy can broadly be divided into non-specific and specific lesions. In this review, we discuss various oral manifestations in leprosy patients so as to increase the awareness about this aspect among dermatologists and dental surgeons

    Feasibility of C-arm guided closed intramedullary pinning for the stabilization of canine long bone fractures

    Aim: To evaluate the feasibility of C-arm guided closed intramedullary pinning (simple Steinmann and end threaded) techniques for the stabilization of various canine long bone fractures. Materials and Methods: The present study was conducted on 19 dogs with long bone fractures which were stabilized using simple Steinmann (Group I; n=6) and end threaded (Group II; n=13) pinning under C-arm guidance. Signalment, history of trauma, clinical examination, and hematobiochemical findings were recorded at the time of presentation. Radiography of the affected limb was carried out in two views to determine type and site of the fracture. Treatment of all the fractures was attempted using simple Steinman and end threaded pinning under the C-arm guidance. The success and failure of the closed technique were correlated with age, site, and type of fractures. Results: The mean body weight and age of the dogs were 18.53±2.18 kg and 21.58±5.85 months, respectively. Early presented cases at a mean day of 2.84±0.54 were included. Out of 19 cases, it was possible to place implant successfully in 10 cases (success rate 52.63%) only. The remaining 9 cases had serious intraoperative complications like a misdirection of the pin after engaging the proximal fragment (n=3), missing the proximal fragment completely, and formation of the false tract (n=6). The majority of these complications were associated with younger age and proximal or distal third oblique fractures. High success rate of C-arm guided closed pinning was observed in midshaft fractures (75%) and transverse fractures (77.78%) in dogs of more than 1 year of age (77.78%). Simple Steinmann pinning was better feasible in a closed manner with a high success rate (66.70%) but also had implant related complications. Although, C-arm guided end threaded pinning was less (46.15%) successful, slightly tedious and time-consuming but had better implant stability than that of simple intramedullary pinning. Conclusions: From the present study, it was concluded that C-arm guided closed pinning is recommended in transverse and midshaft fractures of the long bones in dogs older than 1 year of age. Furthermore, there is need to improve traction devices for enhancing the success of C-arm guided intramedullary pinning in dogs
