Anterior crossbite is a malocclusion frequently found in deciduous and mixed dentitions, it can be classified as dental, skeletal or functional. This last one has a favorable prognosis when the treatment occurs in early stages. Considering this, Planas direct tracks have been showing to be an effective and less invasive alternative when few dental elements are involved. This paper presents a clinical case of a 6-year-old patient with functional unilateral anterior crossbite whose differentiated diagnosis and early intervention allowed a successful treatment. By manipulating the jaw and positioning the condyles in centric relation (CR), the presence of occlusal interference between the upper and lower deciduous canines on the right side was noticed, which are the causes of mandible anterior displacement with occlusion in MIH. For correction, Planas direct track therapy was used on the upper right canine with composite resin followed by slight wear on the lower right canine. The premature contacts were eliminated, creating an inclined plane of approximately 45 degrees on the palatal face of the upper canine and a slight occlusal adjustment on the incisal surface of the lower right canine. The use of this technique allowed the correction of the functional anterior crossbite immediately after the removal of the occlusal interference. This case shows that the early treatment of crossbites increases the chances of a successful rehabilitation of stomatognathic system. The use of Planas direct tracks proved to be an effective, low-cost, and easy to implement alternative for functional crossbites correction.

Background. In recent years, various methods of combined anesthesia during abdominal surgery have been introduced into clinical practice.Aim. To demonstrate the possibilities of a combination of high prolonged spinal anesthesia and endotracheal anesthesia during abdominal surgery.Materials and methods. A clinical case of combined use of high prolonged spinal anesthesia and endotracheal anesthesia in a 48-year-old patient with a tumor in the right half of the ascending part of the right half of the colon is presented.Results. The patient received a puncture of the spinal space at a standard point and was installed a spinal catheter in the cranial direction for 3 cm. An isobaric solution of marcaine in the initial dose of 20 mg was injected into the catheter. The regulation of the development of the block was regulated by the inclination of the head end of the table by 60°. After that endotracheal anesthesia was performed on the basis of fentanyl and propofol. This combination allowed to expand the scope of surgical intervention, provided adequate pain relief intraoperatively and in the postoperative period, without the use of narcotic analgesics. With the appearance of signs of recovery of pain sensitivity, intraoperatively or in the postoperative period, re-introduction of the anesthetic into the spinal catheter was performed in half of the initial dose with liquor barbotage. In the early postoperative period, the patient was on strict bed rest with a head end of the bed raised at 30–45°. The method provides complete segmental blockade and muscle relaxation in the area of operation, stability of central hemodynamics during surgery and in the postoperative period.Conclusion. This type of anesthesia is more easily tolerated by patients, accompanied by early awakening and extubation, characterized by stability of central hemodynamics, reduced risk of complications, the possibility of prolonging anesthesia with lower doses of narcotic analgesics in the intraoperative period, providing high-quality anesthesia in the postoperative period without resorting to the use of narcotic analgesics.

Abstract: Intracranial aneurysm is one of the most common neurovascular complications. During the recent years the accepted treatment of enraptured cranial aneurysm is noninvasive endovascular coiling. This technique is modern but it is not without complications which can be serious and life-threatening. A clinical case of a patient admitted to the ICU of Military Medical Academy - Sofia with sub arachnoid hemorrhage is described. After a positive clinical course, the check-up magnetic resonance showed intracranial aneurism of the right carotid artery. The patient underwent angiographic endovascular treatment. Vasospasm of the middle and right brain artery and thrombosis were detected during the procedure. Attempt of thromboaspiration was made without success. This article reviews published data on broad-spectrum researches concerning complications of endovascular coiling of intracranial aneurysms and the ways to prevent and reduce them.

With the rapid growth of wearable computing and increasing demand for mobile authentication scenarios, voiceprint-based authentication has become one of the prevalent technologies and has already presented tremendous potentials to the public. However, it is vulnerable to voice spoofing attacks (e.g., replay attacks and synthetic voice attacks). To address this threat, we propose a new biometric authentication approach, named EarPrint, which aims to extend voiceprint and build a hidden and secure user authentication scheme on earphones. EarPrint builds on the speaking-induced body sound transmission from the throat to the ear canal, i.e., different users will have different body sound conduction patterns on both sides of ears. As the first exploratory study, extensive experiments on 23 subjects show the EarPrint is robust against ambient noises and body motions. EarPrint achieves an Equal Error Rate (EER) of 3.64% with 75 seconds enrollment data. We also evaluate the resilience of EarPrint against replay attacks. A major contribution of EarPrint is that it leverages two-level uniqueness, including the body sound conduction from the throat to the ear canal and the body asymmetry between the left and the right ears, taking advantage of earphones' paring form-factor. Compared with other mobile and wearable biometric modalities, EarPrint is a low-cost, accurate, and secure authentication solution for earphone users.

Abstract Background During COVID-19 pandemic, optimization of the diagnostic resources is essential. Lung Ultrasound (LUS) is a rapid, easy-to-perform, low cost tool which allows bedside investigation of patients with COVID-19 pneumonia. We aimed to investigate the typical ultrasound patterns of COVID-19 pneumonia and their evolution at different stages of the disease. Methods We performed LUS in twenty-eight consecutive COVID-19 patients at both admission to and discharge from one of the Padua University Hospital Intensive Care Units (ICU). LUS was performed using a low frequency probe on six different areas per each hemithorax. A specific pattern for each area was assigned, depending on the prevalence of A-lines (A), non-coalescent B-lines (B1), coalescent B-lines (B2), consolidations (C). A LUS score (LUSS) was calculated after assigning to each area a defined pattern. Results Out of 28 patients, 18 survived, were stabilized and then referred to other units. The prevalence of C pattern was 58.9% on admission and 61.3% at discharge. Type B2 (19.3%) and B1 (6.5%) patterns were found in 25.8% of the videos recorded on admission and 27.1% (17.3% B2; 9.8% B1) on discharge. The A pattern was prevalent in the anterosuperior regions and was present in 15.2% of videos on admission and 11.6% at discharge. The median LUSS on admission was 27.5 [21–32.25], while on discharge was 31 [17.5–32.75] and 30.5 [27–32.75] in respectively survived and non-survived patients. On admission the median LUSS was equally distributed on the right hemithorax (13; 10.75–16) and the left hemithorax (15; 10.75–17). Conclusions LUS collected in COVID-19 patients with acute respiratory failure at ICU admission and discharge appears to be characterized by predominantly lateral and posterior non-translobar C pattern and B2 pattern. The calculated LUSS remained elevated at discharge without significant difference from admission in both groups of survived and non-survived patients.

An optical fiber solution-concentration sensor based on whispering gallery mode (WGM) is proposed in this paper. The WGM solution-concentration sensors were used to measure salt solutions, in which the concentrations ranged from 1% to 25% and the wavelength drifted from the left to the right. The experimental results showed an average sensitivity of approximately 0.372 nm/% and anR2linearity of 0.8835. The proposed WGM sensors are of low cost, feasible for mass production, and durable for solution-concentration sensing.

Abstract Measuring the motion of human hand joints is a challenging task due to the high number of DOFs. In this study, we proposed a low-cost hand tracking system built on action cameras and ArUco markers to measure finger joint rotation angles. The lens distortion of each camera was corrected first via intra-calibration and the videos of different cameras were aligned to the reference camera using a dynamic time warping based method. Two methods were proposed and implemented for extracting the rotation angles of finger joints: one is based on the 3D positions of the markers via inter-calibration between cameras, named pos-based method; the other one is based on the relative marker orientation information from individual cameras, named rot-based method. An experiment was conducted to evaluate the effectiveness of the proposed system. The right hand of a volunteer was included in this practical study, where the movement of the fingers was recorded and the finger rotation angles were calculated with the two proposed methods, respectively. The results indicated that although using the rot-based method may collect less data than using the pos-based method, it was more stable and reliable. Therefore, the rot-based method is recommended for measuring finger joint rotation in practical setups.

Hemifacial Microsomia (HFM) is a term used to identify facial deformities associated with the development ofthe first and second pairs of branchial arches, characterized by underdevelopment of one half of the face. One typeof hemifacial microsomia is oculo-auriculo-vertebral dysplasia or Goldenhar syndrome.The incidence of HFM is 1:3500-1:7000 of live births and occurs in 1 case per 1000 children with congenitaldeafness. The ratio of boys to girls is 3:2. The etiology and type of inheritance is studied insufficiently. There are threepossible pathogenetic models: vascular abnormalities and hemorrhages in the craniofacial region, damage of Meckel'scartilage, and abnormal cell development of the cranial nerve crest. Environmental factors, maternal internal factors,and genetic factors (OTX2, PLCD3, and MYT1 mutations) may also cause the development of hemifacial microsomia.The article demonstrates a clinical case of hemifacial microsomia in a newborn boy from a mother with Z-21 inthe form of deformation of the left auricle with atresia of the auditory canal and "false" ears on the right, combinedwith congenital anomaly of heart (atrial septal defect) and brain (hypoplasia of the corpus callosum).Emphasis is placed on the need of involving a multidisciplinary team of specialists in the management of thispatient both in the neonatal period and in the system of subsequent follow-up.
