Postoperative bleeding is common in patients undergoing cardiac surgery with cardiopulmonary bypass. Most cases of severe postoperative bleeding not due to incomplete surgical hemostasis are related to acquired transient platelet dysfunction mediated by platelet activation during contact with the synthetic surfaces of the cardiopulmonary bypass equipment. Antihypertensive agents nitroglycerin and sodium nitroprusside have been shown to have platelet inhibitory properties, yet the clinical consequence in terms of postoperative bleeding has been little studied. Knowing that cardiopulmonary bypass causes platelet dysfunction, it is prudent for physicians to be aware of the additional platelet inhibition caused by these commonly used antihypertensive agents.

A technique is described for the intermittent collection of blood from the rat tail. By using commonly available equipment, blood samples can easily be obtained from rats without the need for anaesthesia. The development of this technique makes the rat more readily available as an animal model for repeated withdrawals of small blood samples for pharmacokinetic or bioavailability evaluations.

The authors’ previous papers demonstrated that an air-separator is the most effective equipment among various different types for the improvement of unstable characteristics of an axial-flow rotor. Further experiments revealed that this equipment could eliminate the unstable characteristics thoroughly even for a build which originally accompanied a heavy rotating stall. This paper describes the geometric conditions to realize this and discusses its performance mechanism on the basis of the experiments showing the discharge distribution of the bleeding flow from the blade tip to separator passage as well as the pressure distribution in a blade passage at the tip section of the rotor. It is suggested that the equipment is equally useful at any stage of a multistage rotor.

Background: Uncontrolled bleeding is the leading cause of preventable death from trauma. The Stop the Bleed (STB) initiative provides basic education about bleeding to potential immediate responders. The present study aimed to assess the perceptions of self-efficacy and school preparedness related to responding to a life-threatening bleeding emergency in school personnel at an urban high school. Methods: High school personnel from an urban high school ( N = 156) completed a 1-hour STB course that included a didactic and hands-on component. Participants rated their agreement with statements about self-efficacy and school preparedness on a 5-point Likert-type scale, responded to items regarding how school personnel could be better prepared for life-threatening emergencies, and had the option to provide written responses pre- and post-course. Findings: Independent samples t tests revealed that perceptions of self-efficacy and school preparedness increased after the course ( p < .001). Before the course, 87% of participants felt they needed training, 80% felt the school needed clearer procedures, and 74% felt the school required more equipment for a life-threatening bleeding incident compared with 63%, 69%, and 78% post-course, respectively. Thematic analysis of written responses revealed that participants desired higher frequencies of STB training, more equipment, clearer school procedures, and realistic training scenarios with students. Conclusions/Application to Practice: The STB course increased both perceptions of self-efficacy and school preparedness in a sample of high school personnel. Qualitative analyses provided insight to personnel’s opinion of STB’s effectiveness and what is necessary to maintain or follow through with this knowledge after completion of the course.

Currently, endoscopic hemostasis is the «gold» standard in the treatment of patients suffering from ulcerative gastroduodenal bleeding. General mortality in ulcerative gastroduodenal bleeding according to the Department of ambulance organization of the research Institute of emergency care. I.I. Dzhanelidze in St. Petersburg in 2016 was 5%, and postoperative8,5%. Transcatheter arterial embolization, due to the development of endovascular hemostasis techniques, is an alternative to palliative surgery in the failure of conservative treatment of ulcerative gastroduodenal bleeding using endoscopic hemostasis techniques, especially in the group of patients with high risk of surgery and adverse outcome. It was found that the reduction in mortality in patients with gastric ulcer bleeding can be achieved by reducing the number of palliative interventions, wider use of angiographic embolization for the prevention and treatment of recurrent bleeding and expanding indications for urgent radical operations outside the recurrence of hemorrhage. The use of transcatheter arterial embolization in elderly patients with severe somatic pathology and recurrent gastric ulcer bleeding can prevent the recurrence of bleeding and perform hemostasis. The success of the transcatheter arterial embolization procedure depends on many factors. Primarily from the anatomical features of the patient. In one case, the patient had a 60% stenosis of the proximal segment of the gastrointestinal splenic trunk, which did not allow the procedure to be performed. Important is the choice of agents for embolization depending on the location and diameter of the source of bleeding. Success also depends on the technical equipment of the hospital and the experience of the surgeon. The absence of significant differences in mortality between the main and control groups, in our opinion, is due to the severity of the General somatic condition of patients included in the study. The obtained results determine the need for further studies to optimize the indications and methods of transcatheter arterial embolization in emergency surgery of gastroduodenal bleeding.

The purpose of the study was an index assessment of the state of the gums in children in whom fixed equipment was used for the treatment of orthodontic pathology. Materials and methods. 89 children aged 14 to 17 years old with a fully formed permanent occlusion were examined. Group 1 included 31 children (34.8% of the total number) with occlusion pathology; group 2 – 36 children (40.4%) with occlusion pathology in combination with crowding of teeth; children of these groups were treated with the use of fixed orthodontic equipment; group 3 consisted of 22 children (24.7%) without orthodontic pathology. Rational oral hygiene was taught to all children. The assessment of the state of the gums was carried out according to the papillary-marginal-alveolar index in the modifications of M. Masser (1948) and C. Parma (1960) in points and percentages, and in accordance with the papillary bleeding index by U. Saxer and H. Műhlemann (1975). The initial index values were determined after 1 and 3 months. Results and discussion. In children of group 1, the papillary-marginal-alveolar index increased significantly from the initial values of 0.47 ± 0.03 points and 15.81 ± 1.09% (р˂0.05) to 0.80 ± 0.05 points and 26.77 ± 1.62% within 1 month and further decreased insignificantly (р˃0.05) to 0.73 ± 0.03 points and 24.19 ± 1.10% within 3 months. In the same period, the same dynamics was established in children of group 2, the corresponding indicators were 0.76 ± 0.03 points and 25.49 ± 1.11%; 1.18 ± 0.03 points and 39.31 ± 0.93% and 1.11 ± 0.04 points and 36.96 ± 1.32%. Children of group 3 had different dynamics with a gradual decrease in values – 0.31 ± 0.03 points and 10.30 ± 1.14%; 0.22 ± 0.02 points and 7.42 ± 0.66% and 0.20 ± 0.02 points and 6.52 ± 0.81%. Bleeding gums according to the papillary bleeding index in children of group 1 in the corresponding periods first increased significantly (р˂0.05) from 0.53 ± 0.03 points to 1.12 ± 0.04 points, then decreased significantly (р˂0.05) to 0.89 ± 0.03 points. In children of group 2, the indicators were significantly (р˂0.05) the highest in all terms with the same dynamics – 0.84 ± 0.03 points; 1.26 ± 0.03 points and 1.09 ± 0.03 points, respectively. A gradual and unreliable (р˃0.05) decrease in indicators from 0.25 ± 0.04 points to 0.24 ± 0.03 points and 0.19 ± 0.03 points was registered in the children of group 3. Conclusion. In the presence of occlusion pathology in children, as well as such pathology in combination with crowding of teeth during orthodontic treatment with the use of fixed equipment, the papillary-marginal-alveolar and papillary bleeding indices during one and three months of treatment increase significantly (р˂0.05) in comparison with the initial level, which can be justified by the aggravating effect of fixed orthodontic equipment and deterioration of the hygienic condition of the oral cavity in these children associated with it

Today, the veterinarian is increasingly in veterinary practice began to use new modern technologies for the treatment of small pets, using modern equipment for medical manipulations. At present, a modern operating room can no longer be imagined without a ventilator and a device for giving inhalation anesthesia. But, even new modern equipment and modern drugs for performing anesthesia cannot protect against medical errors. One of the most important manipulations is the ability to correctly place the endotracheal tube to perform resuscitation or give inhalation anesthesia. The percentage of iatrogenic injuries during this procedure reaches 2.5 % and is complicated by bleeding and blood aspiration, which requires emergency assistance, primarily with the use of endosoepic technologies.

A case of successful clinical endovascular treatment for rupture of a splenic artery aneurysm with intraperitoneal bleeding is presented. An emergency open surgery, urgent endovascular aneurysm embolization and planned relaparotomy with the removal of gauze swabs and drains were performed. The staging of surgical treatment was determined by the location of the patient at the time of the complication and the equipment of medical institutions that provided medical care. Regarding the dangerous condition with rupture of the splenic artery aneurysm minimally invasive high-tech surgical care is possible only under certain conditions and depends on the qualifications of doctors, a multidisciplinary approach and the level of equipment of a medical institution. Endovascular embolization of the splenic artery aneurysm when it ruptures is a modern, highly effective and reliable minimally invasive surgical method.

Eighty-seven cases of cardiac arrest from the first 2000 incidents reported to the Australian Incident Monitoring Study were reviewed. “Cardiac arrest” was taken to include patients who were either pulseless or had electrocardiographic asystole or ventricular fibrillation. Cases were grouped by primary cause—drug administration (19), vagal stimulation (16), hypoventilation (15), bleeding (13), anaphylaxis (6), direct cardiac stimulation (4) and miscellaneous (14). Overall, 20 patients died (23% of the 87 cases); all of these were in the hypoventilation, bleeding, or miscellaneous groups (4, 9 and 7 patients, respectively). Cardiac compression was performed in 66% of patients; 20% were defibrillated; adrenaline was given to 42% and bicarbonate to 3%. There was a clear anaesthetic cause for 46% of this series of arrests, and with hindsight, a preventable factor was present in over half (58%) of these. Preventative strategies regarding staffing, equipment, policy and procedures are suggested.

Abstract: The bone is a major component of the human body. Bone provides the ability to move the body. The bone fractures are common in the human body. The doctors use the X-ray image to diagnose the fractured bone. Therefore, an automated system needs to develop to diagnose the fractured bone The Deep Neural Network (DNN) is widely used for the modelling of the power electronic devices. This study showed that a deep learning model can be trained to detect fractures in radiographs with diagnostic accuracy similar to that of senior subspecialized orthopaedic surgeons. The aim of this study is to perform fracture detection by use of deep-learning on X-ray images to support physicians in the diagnosis of these fractures, particularly in the emergency Services. Hospitals, especially their emergency services, receive a high number of fracture cases. For correct diagnosis and proper treatment of these, images obtained from various medical equipment must be viewed by physicians, along with the patient’s medical records and physical examination. Recent advancement in image processing and deep learning create some hopes in devising more enhanced applications. Therefore, data augmentation techniques have been used to increase the size of the data set

Abstract A novel immunochemical test, "Hemolex," is characterized and compared with three guaiac tests: "Hemoccult" (Smith-Kline, U.S.A.), "Hemofec" (Boehringer Mannheim, F.R.G.), and "Fecatwin Sensitive" (Labsystems, Finland). We tested 191 stool specimens from patients, 144 from healthy persons. The sensitivity of Hemolex was 0.6 mL of blood per 100 g of stool. It reacts with neither animal hemoglobin nor human myoglobin, unlike the guaiac tests, nor does it react with the stool of healthy persons under no dietary restrictions, while the guaiac tests react variably. As a rule, Hemolex is insensitive to bleeding in the upper gastrointestinal tract, unlike the guaiac tests. However, Hemolex seems to be more sensitive to bleeding in the lower gastrointestinal canal than are the other tests, and we show it to be suitable for screening for occult blood originating there. It is unaffected by diet. It is simple to perform, requires no special equipment, and stool specimens, stored in the test diluent, are stable for testing for two weeks.

Introduction: Trauma is a problem faced everyday in the emergency room of the hospital where the researcher works. The degree of trauma from the mildest to life threatening can be found in sufferers. The cause of death in trauma sufferers is hypovolemic shock due to bleeding. The amount of blood loss volume from the patient can be estimated by looking at the clinical signs of the patient. Literature Review: In the condition of tissue hypoperfusion, it will cause a chain process which will eventually lead to cell death. Hypoperfusion causes anaerobic metabolism, lactic acidosis (coagulopathy, enzyme dysfunction), Na-K pump malfunction (cellular swelling and cell death), there is hypothermia (increase of oxygen demand, coagulopathy). Hypoperfusion will cause a vicious circle, in which processes that aggravate one another will occur. With the administration of fluids (crystalloid, colloid, transfusion) will improve the hypoperfusion that occurs in the body. Conclusion: The management of hypovolemic shock due to bleeding requires an understanding of the physiology and pathophysiology that occurs due to bleeding. To get maximum results and improve outcome from sufferers, it needs solid team work. Treatment can be different depending on the conditions, equipment and facilities of the hospital / emergency room as well as the policies of each place.

Optimal regimens using recent radiotherapy (RT) equipment for bleeding gastric cancer (GC) have not been fully investigated yet. We retrospectively reviewed the clinical data of 20 patients who received RT for bleeding GC in our institution between 2016 and 2021. Three-dimensional conformal RT was performed. The effectiveness of RT was evaluated by the mean serum hemoglobin (Hb) level and the number of transfused red blood cell (RBC) units 1 month before and after RT. The median first radiation dose was a BED of 39.9 Gy. The treatment success rate was 95% and the rebleeding rate was 10.5%. There was a significant increase in the mean Hb level (8.0 ± 1.1 vs. 9.8 ± 1.3 g/dL, p = 0.01), and a significant decrease in the mean number of transfused RBC units (6.8 ± 3.3 vs. 0.6 ± 1.5 units, p < 0.01). Severe toxicity was observed in two patients (anorexia [n = 1] and gastrointestinal [GI] perforation [n = 1]). Reirradiation was attempted in three patients (for hemostasis [n = 2] and for mass reduction [n = 1]). The retreatment success rate for rebleeding was 100%. GI perforation occurred in two patients who had received hemostatic reirradiation. Palliative RT for bleeding GC using recent technology had excellent efficacy. However, it may be associated with a risk of GI perforation.

The graphs of the time dependence of the temperature change of the control points of the laboratory sample of TEC for stopping bleeding by the method of local freezing of the blood flow zone at various supply currents of the thermoelectric battery (TEB) were obtained. The control points were cold and hot junctions of TEB, a simulator of a biological object. Conclusion. The data obtained show that with an increase in the area of blood flow, it takes more time to stop it. An increase in the diameter of the hole with blood flow by an average of 1 mm increases the duration of thrombus formation, which stops bleeding by an average of 20 s. During the experiment, it was found that to ensure the efficient operation of the TEU, it is sufficient to use the commercially available TEB brand ICE- 71.

Endoscopic ultrasound fine-needle aspiration (EUS-FNA) is used to make a cytopathologic diagnosis of suspicious lesions located around the gastrointestinal tract. It is a safe technique with few complications. The most common complications of EUS-FNA are related to pancreatic lesions (pancreatitis, bleeding, and abdominal pain). Rare complications have been noted such as stent malfunction, air embolism, infection, neural and vascular injuries, and tumor cell seeding. There are very few studies examining equipment malfunctions. We report a case of needle fracture during the EUS-FNA of suspicious thoracic lymph nodes in a 79-year-old man investigated for unexplained weight loss.

Image-enhanced endoscopy (IEE) allows real-time high-contrast imaging of a targeted lesion without any special equipment. Among various IEE technologies, narrow-band imaging, in which a light of shorter wavelength is used, emphasizes the surface and blood vessel patterns on the mucosal surface. This technology has been widely used in endoscopic diagnosis in the gastrointestinal tract. Red dichromatic imaging (RDI) was recently developed; it utilizes lights of longer wavelengths (520–550, 595–610, and 620–640 nm), which have weak light scattering characteristics in contrast to narrow-band imaging. RDI was designed to enhance the visibility of deep-lying blood vessels and areas of bleeding, and it has been installed in the latest Olympus endoscopy system, EVIS X1, as an advanced version of the optical-digital method that was originally developed. Improving the visibility of deep blood vessels allows more accurate evaluation of esophageal varices and the degree of inflammation in ulcerative colitis. Easier identification of a bleeding source makes hemostasis quicker and easier to accomplish during endoscopic resection procedures such as endoscopic submucosal dissection and peroral endoscopic myotomy as well as during treatment of gastrointestinal bleeding from a peptide ulcer or colon diverticulum. The authors herein review the technological development and principles, review the existing literature on RDI, and discuss the utility and effectiveness of this unique IEE technology in gastrointestinal endoscopy.

Development of regulatory energy characteristics of TPP equipment is a mandatory and resource-intensive proce-dure. A mathematical model of the turbine plant (the turbine plant itself and its regenerative feed water heating system) was developed earlier based on the matrix formalization of calculations of the energy and mass exchange installations. The analysis of the modeling results has shown that the model adequately de-scribes the real characteristics of a turbine plant only at low bleeding load. At higher load, the accuracy of description is much lower and the model cannot be used for practical analysis of real equipment. All this means that the turbine model needs to be refined by introducing stage-dependent efficiency indicators for more accurate determination of the equipment energy characteristics and, based on them, developing of computer aided methods for optimizing regimes of technological systems and sub-systems of thermal power plants. Methods of mathematical programming were used to investigate the multi-flow heat and mass exchange systems and sub-systems of thermal power plants on the basis of heat and mass balance equations. The energy characteristics and efficiency indicators of TPP equipment were determined in accordance with the existing normative approach. The turbine plant model has been refined by the matrix formalization method by introducing stage-dependent efficiency indicators. Model solutions have been obtained and analysed in order to calculate energy characteristics of the combined cycle turbine plant. The calculaiton results have been compared with the energy characteristics of a turbine unit in operation. It has been shown that the proposed approach is reliable and reasonable. The obtained results can be used for increasing the validity degree of equipment energy characteristics calculation, creating computer simulators and software tools for optimizing modes of technological systems and subsystems of heat power plants.

Objective Recent evidence suggests that multilevel sleep surgery improves outcomes when compared with palate surgery alone for most patients. The study objective was to compare demographic and outcomes data for palate surgery (uvulopalatopharyngoplasty [UPPP]) alone versus multilevel surgery through a national insurance claims database. Study Design Retrospective cohort study. Setting National insurance claims database. Subjects and Methods An adult cohort undergoing single-level UPPP versus UPPP with nasal and/or tongue/hypopharyngeal surgery was identified in the Truven Health Analytics MarketScan Research Databases for the years 2010 through 2012. Demographic and outcomes data were assessed at short-term (≤14 days), intermediate (15-60 days), and long-term (61-183 days) intervals via a multivariate regression model adjusted for age, sex, geographic region, insurance type, and the Charlson-Deyo comorbidity score. The primary long-term complication considered was positive airway pressure (PAP) equipment supply, implying possible treatment failure. Results The cohort included 14,633 patients: 7559 (51.6%), UPPP alone; 5219 (35.7%), UPPP + nasal surgery; 1164 (7.95%), UPPP + tongue/hypopharyngeal surgery; and 691 (4.7%), UPPP + nasal + tongue/hypopharyngeal surgery. Demographic data were similar among the groups. UPPP alone had lower rates of postoperative bleeding than UPPP + tongue/hypopharyngeal surgery (4.31% vs 6.19%, P = .004). Multivariate modeling indicated that the addition of either nasal surgery (odds ratio = 1.21, 95% CI = 1.10-1.34, P < .001) or tongue/hypopharyngeal surgery (odds ratio = 1.15, 95% CI = 1.00-1.32, P = .048) to UPPP was associated with increased odds of postoperative continuous positive airway pressure. Conclusions UPPP alone is currently the predominant form of sleep surgery in the United States. Multilevel surgery had greater odds of postoperative bleeding and positive airway pressure equipment supply than UPPP alone. Dedicated studies formally evaluating single- versus multilevel sleep surgery and the impact of possible surgeon/patient selection bias should be a priority.

The article discusses the issue of automating the serial process of bleeding and control of the pitot- static system of passenger airplanes. A functional diagram and basic design of some parts of the combined equipment are proposed. This equipment makes it possible to alternate the above-mentioned operations with great effectiveness. At the system control stage, the pressure or vacuum in it is created by a pressure-vacuum pneumatic unit. This pneumatic unit consists of a compressor and a set of electromagnetic valves that allow the compressor to be connected to the pumping or scavenging line. The value of the generated pressure is regulated by the flow rate in the pressure/scavenging channel and in the venting channel. Simulation of changes in ambient temperature is achieved due to blowing heated or cooled air over the temperature sensors of the aircraft. Pressure or vacuum in the controlled system is created in turn, in each of its lines. At the expulsion stage, a compressed-nitrogen cylinder acts as the pressure source. The pressurized gas passes through the pitot and is released into the atmosphere, cleaning out the contaminations. No manual operations are required for installing and removing connection hoses after connecting the proposed combined equipment to the pitot-static system. Remote-controlled electromagnetic valves connect the channels of the controlled system to the pressure-vacuum pneumatic unit and the source of compressed nitrogen. This reduces the duration of successive operations for the systems maintenance.

The aim of the study is the evaluation of results of endoscopic tunnel interventions in submucosal tumors and achalasia.Material and methods. Endoscopic tunnel interventions during 2017–2020 years were performed in 80 patients (34-men, 46-women). The duration of the age ranged from 15 to 72 years. The indications for interventions were: achalasia in 53, subepithelial tumors in 27.Results. During the intervention, complications occurred in 22 patients. Among the complications: carboxyperitoneum in 16 cases, carboxytorax in 2, esophageal mucosa perforation in 2, bleeding moderate intensity bleeding in 2. Most of the complications (20) were in patients with esophageal achalasia. Postoperative complications were observed in two patients operated for esophageal achalasia (bleeding and hematoma, esophageal mucosa necrosis). All patients were treated by using conservative methods. The results of the interventions were assessed in terms of 1 month to 3 years. There were no violations of food or liquid the passage through the cardia. Patients after operation for submucous tumors of the esophagus had no complaints. The main complaint of patients after myotomy was heartburn. Endoscopic examination revealed erosive reflux esophagitis (A-C) in 18 patients.Conclusion. Tunnel endoscopic interventions in patients with esophageal achalasia and submucous tumors are highly effective and low-traumatic, allowing relatively safe restoration of the patency of the cardia and removal of the subepithelial neoplasm. The problem of gastroesophageal reflux after oral endoscopic myotomy requires further accumulation of data in order to develop optimal tactics. The limiting factor for the these operations performance is the material and technical equipment of medical institutions and the lack of trained specialists.

Objectives. Differentiating gastrointestinal stromal tumor (GIST) from other submucosal tumors (SMTs) is important in diagnosing SMT. GIST is an immunohistological diagnosis that cannot be made from images alone. Tissue sampling of tumor sites is thus becoming increasingly important. In this study, the utility and associated complications of mucosal cutting biopsy (MCB) for gastric SMTs were investigated. Methods. This was a case series study. The subjects were patients aged ≥20 years old in whom an SMT was seen on esophagogastroduodenography and who underwent MCB between January 2012 and December 2016. Patient information, endoscopy findings, gastric SMT size, pathological diagnosis, and other information were gathered from medical records. The SMT size was the maximum diameter that could be visualized on EUS. The pathological diagnosis was made with hematoxylin-eosin staining, with immunostaining added to diagnose GIST. The endpoint was the histopathological diagnostic yield. Risk assessment using the Miettinen classification and modified Fletcher classification was also done for GISTs treated with surgery. Results. The mean tumor diameter was 15.4 mm. The tumor diameter was ≥20 mm in seven patients and <20 mm in 23 patients. The tissue-acquiring rate was 93.3%. A histological diagnosis could not be made in two patients. The only complication was that bleeding required endoscopic hemostasis during the procedure in one patient, but no subsequent bleeding or no postoperative bleeding was seen. Conclusions. MCB is an appropriate and safe procedure in the diagnosis of gastric SMTs. Many hospitals will be able to perform MCB if they have the environment, including skills and equipment, to perform endoscopic submucosal dissection.

Ankyloglossia, commonly known as tongue-tie, is the most common disorder of tongue morphology characterized by aberrant attachment of the lingual frenum. This study aimed to provide a comprehensive literature review and evaluate the effectiveness of various laser wavelengths in the surgical treatment of patients with ankyloglossia. An electronic screening of PubMed and the Cochrane Central Register of Controlled Trials (CENTRAL) databases was conducted on 8 November 2021. The following search terms were used to review the available data on the subject of interest: (ankyloglossia OR tongue tie OR short lingual frenulum OR lingual frenectomy OR lingual frenulectomy OR lingual frenotomy OR lingual frenulotomy) AND laser. The use of lasers in ankyloglossia treatment resulted in shorter procedure time, reduced indications for general anesthesia, reduced administration of postoperative analgesics, fewer sutures or none needed, reduced postoperative bleeding, and improved healing. Despite many advantages, this method has its clinical limitations: it requires the use of expensive equipment; well-trained personnel familiar with lasers; and personal protective equipment for the patient, caregiver, operator, and assistant. The laser procedure does not eliminate the need for myofunctional exercises and work with a speech therapist.

Objective. Many surgical approaches have been defined and implemented in the last few decades for thoracic disc herniations. The endoscopic foraminal approach in foraminal, lateral, and far lateral disc hernias is a contemporary minimal invasive approach. This study was performed to show that the approach is possible using the microscope without an endoscope, and even the intervention on the discs within the spinal canal is possible by having access through the foramen.Methods.Forty-two cases with disc hernias in the medial of the pedicle were included in this study; surgeries were performed with transforaminal approach and microsurgically. Extraforaminal disc hernias were not included in the study. Access was made through the Kambin triangle, foramen was enlarged, and spinal canal was entered.Results.The procedure took 65 minutes in the average, and the mean bleeding amount was about 100cc. They were mobilized within the same day postoperatively. No complications were seen. Follow-up periods range between 5 and 84 months, and the mean follow-up period is 30.2 months.Conclusion.Transforaminal microdiscectomy is a method that can be performed in any clinic with standard spinal surgery equipment. It does not require additional equipment or high costs.

The utilization of rescue blankets in pre-hospital emergency medicine exceeds protection from hypothermia and enhanced visibility by far. In this narrative review, we focus on emphasizing the alternative applications of these fascinating multifunctional tools in the pre-hospital setting. A literature search in PubMed® and Web of ScienceTM yielded 100 results (last update was on 8 July 2022), a total number of 26 of which were included in this narrative review. Nine articles assessing alternative functions of rescue blanket were further evaluated and described in more detail. In addition, we performed various experimental and observational trials to test the functionality of rescue practice in mountain emergency medicine. Newly fabricated rescue blankets proved to possess impressive robustness. We evaluated rescue blankets in their applicability to not only protect from hypothermia, but also as practical tools to treat catastrophic hemorrhage and bleeding limbs, to perform open pneumothorax chest seals in sucking chest wounds, to prevent damage to unprotected eyes on the glacier and as alternative instruments for transportation in the inaccessible areas. Rescue blankets are important rescue equipment in alpine and wilderness emergencies with multifunctional applications, and must be part of every personal medical kit.

Abstract Epistaxis represents a commonly encountered manifestation in the ENT Emergency Department. Healthcare providers working in the ENT Emergency Department are at high risk of COVID-19 infection both because of the high viral load in the upper airways and because of the asymptomatic presentation of COVID-19 disease. Special focus is needed for managing the balance between appropriate patient care and ensuring the safety of healthcare workers. Adequate preparation and modification of the procedures for bleeding control to minimize risk of spread is necessary. While managing, attention should be kept on less invasive methods with avoidance of aerosol-generating activities. Nonetheless, proper use and disposal of personal protective equipment is of utmost importance in stopping the spread of COVID-19.

AbstractEighty-seven patients who were treated by laser mucotomy (L-mucotomy) of the inferior turbinates were followed-up for one year. Patients presented for laser surgery because of one of the three following symptoms: sneezing, rhinorrhoea, or nasal obstruction. All of them had had prior conservative or surgical treatments for their symptoms without improvement in their complaints and/or quality of life. L-mucotomy is a simple procedure performed under local anaesthesia on an ambulatory basis. A controlled amount of tissue from the inferior turbinates is ablated with improvement in the symptoms, as reported by the patients one year after laser surgery.The procedure is easy to perform, there is no bleeding, it is painless and without complications, but it requires rather expensive surgical equipment.

Inherited bleeding disorders (IBDs) are the most frequent congenital diseases in the Colombian population; three of them are hemophilia A (HA), hemophilia B (HB), and von Willebrand Disease (VWD). Currently, diagnosis relies on multiple clinical laboratory assays to assign a phenotype. Due to the lack of accessibility to these tests, patients can receive an incomplete diagnosis. In these cases, genetic studies reinforce the clinical diagnosis. The present study characterized the molecular genetic basis of 11 HA, three HB, and five VWD patients by sequencing the F8, F9, or the VWF gene. Twelve variations were found in HA patients, four in HB patients, and 19 in WVD patients. From these variations a total of 25 novel variations were found. Disease-causing variations were used as positive controls for validation of the high-resolution melting (HRM) variant-scanning technique. This approach is a low-cost genetic diagnostic method proposed to be incorporated in developing countries. For the data analysis, we developed an accessible open-source code in Python that improves HRM data analysis with better sensitivity of 95% and without bias when using different HRM equipment and software. Analysis of amplicons with a length greater than 300 bp can be performed by implementing an analysis by denaturation domains.

Background: Current national guidelines for the use of ultrasound in early pregnancy state that the embryonic heartbeat should be identified when the embryo measures 6 mm in length (RCOG/RCR 1995). Failure to visualise heart pulsations in embryos measuring 6 mm or less requires patients to wait 7 days for a repeat scan. Anecdotally, there is evidence to suggest that it is usually possible to see embryonic heart pulsation much earlier using modern ultrasound equipment. The aim of this study was to identify the smallest length of embryo when it is possible to always visualise heart pulsations during an ultrasound examination. Method: This was a prospective observational study of women attending the early pregnancy unit of a large teaching hospital. Women were invited to participate when a clinically indicated ultrasound examination revealed an intrauterine pregnancy with an embryo measuring 6 mm or less. All women were symptomatic, i.e. they presented with pain and/or bleeding in early pregnancy. The presence or absence of discernible embryonic cardiac activity was recorded at the initial ultrasound examination, and any follow-up ultrasound examination, along with the crown rump length (CRL) of the embryo. Results: The study sample consisted of 95 embryos with CRL range 1·2–6 mm. Visible heart pulsations were seen in 80 (84%) embryos at the initial examination. In 15 embryos, no discernible heart pulsation was noted; in all 15 cases, these pregnancies went on to miscarry: this was confirmed at a follow-up examination 7 days later. Conclusion: In early pregnancy ultrasound, cardiac activity should be visualized in all live embryos as soon as the embryo can be identified reliably. The absence of heart pulsations in very small embryos is indicative of pregnancy demise, regardless of the actual size of the embryo.

This paper introduces development and application of ultra-high strength/high performance concrete in construction of the Xita tower high-rise building at Zhujiang New City of Guangzhou, China. The goal of the concrete construction in the Xita Tower project will be realized via research of mix proportion and optimization of pumping equipment. In regard to mix proportion of concrete, low water/cement (W/C) ratio, low water content lower than 150 kg/m3 and employment of superplasticizer are essential to acquire high strength. A series of parameters have been measured to research workability of concrete from C70 to C90, such slump, slump flow, flow time from inverted cone, L-box flow, and bleeding under pressure et al. Properties of hardened concrete should also be considered, including durability, autogenous shrinkage caused cracking, and fire resistance.

Objectives: The systematic review objective was designed to assess the effects of local interventions used for the prevention and treatment of pain associated with orthodontic treatments. Methods: A digital literature search was carried out between 2000 and 2022 in the following databases, Scopus, Google Scholar, PubMed, and the Cochrane Library of Systematic Reviews. Results: Orthodontic patients' quality of life was significantly impacted negatively by the discomfort associated with fixed orthodontic equipment. There were poor dental hygiene, slurred speech, difficulty chewing, movable teeth, decreased taste, halitosis, and gingival bleeding which were frequently the main indicators of pain. Conclusion: Patients might, to some extent, prevent pain and suffering with the support of effective orthodontist- patient dialogue and targeted dietary guidance. However, analgesics continue to be a trusted and widely used method for subsiding painful sensations.

Introduction: Traumatic vascular injury is caused by explosions and projectiles which may affect arteries and veins of the limbs, and is common in wartime and RTA, triggering bleeding and ischemia. The increasing use of high-energy weapons in modern warfare is associated with severe vascular injuries. The peripheral arteries and veins of the extremities are among the most commonly injured vessels in both civilian and military vascular trauma. Vascular injuries are classified as contusion, intimal disruption, puncture, lateral disruption, transections with hemorrhage or occlusion, arteriovenous fistula, spasm, and pseudoaneurysms. Any kind of bleeding whether inside or outside of the body is a sign of vascular trauma. Symptoms of vascular trauma include bleeding, swelling and/or pain, bruising, and a lump beneath the skin (haematoma). Patients with emergency peripheral vascular injury are usually diagnosed clinically. Non-invasive tests may confirm the diagnosis and are useful in-patient follow-up. Invasive tests can document the lesion and extent of disease if angiogram, angioplasty, local fibrinolytic therapy, or surgical bypass is contemplated. With the change of time background, the treatment of vascular injury is also changing. Nowadays advanced medical equipment provides benefits to patients with vascular injuries. Meanwhile, traditional treatments are still playing an important role. If vascular trauma has not been treated in time, it may cause disability or even death, especially for limb vascular injury. There are several management options for traumatic peripheral vascular injury including some interventional and non-interventional therapies. The study aimed to analyze the Success Rate of different management options for traumatic peripheral vascular injury. Methods: This retrospective study was carried out among fifty cases who attended in the vascular surgery department at the National Institute of Cardiovascular Disease (NICVD) and casualty block, .....

Pseudoaneurysm of the uterine arteries is a rare cause of secondary postpartum haemorrhage (PPH), following caesarean section or vaginal delivery. Whilst uterine artery embolization serves as an important and effective treatment for most cases of symptomatic uterine artery pseudoaneurysm, it is not without the risk of failing. Herein, we report a case of a near missed uterine artery pseudoaneurysm with nidus measuring about 1.7 x 2.7 x 2.8 cm. presenting as secondary postpartum haemorrhage 19 days post lower segment caesarean section, who underwent bilateral uterine arteries embolisation using Polyvinyl Alcohol (PVA) particles and gel foam until near stasis. Immediate check angiogram post uterine artery embolization (UAE) in our case reveals no residual pseudoaneurysm, however our patient had recurrent bleeding 2 days following the procedure. Repeated transabdominal ultrasound following recurrent bleeding showed similar size of colour doppler uptake at uterine fundus which indicates reperfusion of the pseudoaneurysm. Block the roads and lock the doors, the recurrent bleeding was managed successfully with prolonged Bakri Balloon tamponade. This case report was written with the objective of identifying the role of balloon tamponade as a method in the treatment of secondary PPH secondary to uterine arteries pseudoaneurysm. We also aim to show that with colour doppler ultrasounds as a basic imaging equipment in obstetric hospitals, we can spare the repercussion of a missed diagnosis of uterine artery pseudoaneurysm. Bakri Balloon used as uterine tamponade may be a treatment of choice with single lesion pseudoaneurysm which protrudes into the uterine cavity and not involving the lower segment of the uterus. Further studies however are needed to determine the size of pseudoaneurysm suitable for obliteration using prolonged balloon tamponade.International Journal of Human and Health Sciences Supplementary Issue-2: 2021 Page: S6

The aim of the study was to evaluate the release of the lingual frenulum through frenectomy in newborns zero to 90 days of age who breastfed and had diagnosis of ankyloglossia with an indication for surgery, comparing two methods: electrocautery and a high-power diode laser. Fifty-seven patients were randomly allocated to two groups (23 submitted to electrocautery and 34 submitted to a high power diode laser). Tongue movements were evaluated based on a clinical assessment and using the Bristol Tongue Assessment Tool (BTAT) before and 15 days after the surgical procedures. The visual analog scale was administered to the mothers on the same occasions for the measurement of pain during breastfeeding. Both groups had an increased BTAT score (favorable outcome) at the post-surgical evaluation, but the anterior third of the tongue was not always free to enable the movements necessary for lingual functions. It is fundamental for surgeons to have skill and in-depth knowledge of the equipment used to avoid accidents and complications in the region of important structures. Both techniques employed in this study were safe and effective, causing little bleeding and few postoperative complications. The group submitted to a high-power diode laser exhibited less post-surgical bleeding compared to the group submitted to electrocautery and no inflammation at the edges of the surgical cut.

BackgroundTrauma is a major public health issue. In 2015, the White House launched the “Stop the Bleed” (STB) campaign, which aims to equip would-be bystanders with the ability and equipment to assist in bleeding emergencies. This study sought to estimate the number of patients who might benefit from STB intervention, in an everyday setting, and their spatial injury profile.MethodsThis is a retrospective analysis of trauma registry and medical examiners’ data, collected between 2013 and 2017. The majority of patients were male. The median age was 32 years. Incidents were geocoded by ZIP code, and mapped using Quantum Geographic Information System (QGIS).ResultsWe identified 139 patients from medical examiner records and UAB’s trauma registry who might have benefitted from STB intervention. The number of incidents per year ranged from 22 to 35, averaging 2.3 incidents per month. There was no evidence of geographical clustering, although the small number of incidents precluded a formal geostatistical analysis.ConclusionThe number of patients who might benefit from STB interventions on a daily basis is small, and incident locations are difficult to predict. Educating the public in how to stop bleeding is appealing, but providing easy and widespread access to STB kits may be difficult. Although there are parallels to the provision of cardiopulmonary resuscitation and defibrillation for cardiac arrest, there are also differences, which should not be overlooked.

A disproportionate burden of gynecologic malignancies occurs in low- and middle-income countries. Radiation therapy is an integral component of treatment for gynecologic malignancies both from a curative (locally advanced cervical cancer) and palliative (bleeding cervical or pelvic mass) standpoint. Critical to understanding how better to serve patients in this regard is understanding both the extent of disease epidemiology and the radiotherapy infrastructure to treat these diseases. In this review, we explore various geographic regions and how they address a unique set of challenges specific to the peoples and culture of the region. We identify common threads across regions, including sparse distribution of radiation equipment, geographic access, and specialized training. We also highlight examples of success in the use of telemedicine and cross-cultural partnerships to help bolster access to training to ensure increased access to adequate and appropriate treatment of gynecologic malignancies.

John Gibbon conceived cardiopulmonary bypass (CPB) and performed the first intracardiac repair using extracorporeal perfusion in 1953. This achievement stimulated rapid development of the knowledge base and equipment necessary for accurate diagnoses and successful intracardiac operations. In the early 60s increasing evidence indicated that exposure of blood to nonendothelial cell surfaces produced bleeding and thrombotic complications and a massive inflammatory response. Early efforts to discover a synthetic, nonthrombogenic surface gave way to efforts to control the ‘whole-body inflammatory response’ by pharmacological means. These efforts are ongoing; progress is slow; and heparin is still required for most applications of extracorporeal perfusion technology. Nevertheless, CPB now enables over one million cardiac surgical operations each year. Future progress and the development of artificial internal organs that process blood depend upon control of the blood -surface interface without anticoagulants.

Background. A meta-analysis was performed to evaluate the effectiveness and safety of ultrasonic osteotomes in spine surgery to standard spinal surgery procedures. Methods. Using the search keywords “bone curette”, “cutter”, “scalpel”, “bone shaver”, “aspirator”, “osteotome”, “ultrasonic”, “piezosurgery”, and “ dent ∗ ” in the databases of PubMed (1966-2021.12), Cochrane Library, Embase (1986-2018.12), Web of Science (1978-2021.12), and China Academic Journals Full-Text Database (CNKI, 1979-2021.12). Two researchers reviewed the literature, extracted and extensively assessed the data, and included information on the study quality. RevMan v5.3.5.0 was used for the meta-analysis. Results. A total of 10 trials with a total of 911 patients were included. The meta-analysis findings revealed that, when compared to traditional methods, ultrasonic osteotomes could save operation time ( OR = − 18.83 , 95 percent CI (-22.76, -14.99), P = 0.03 ) and reduce intraoperative bleeding ( OR = − 66.73 , 95 percent CI (-75.70, -57.76), P = 0.04 ) and postoperative complications ( OR = 0.38 , 95 percent CI (0.21, 0.69), P = 0.001 ). There was, however, no significant difference in the hospital stay ( OR = − 1.34 , 95 percent CI (-1.90, -0.77), P = 0.23 ) and symptom improvement rate ( OR = 1.03 , 95 percent CI (0.73, 1.45), P = 0.86 ). Conclusion. There is evidence that using an ultrasonic osteotome in spine surgery is safe and effective and may minimize intraoperative bleeding and save time. However, there is no significant difference in symptom improvement rate, hospital stay length, or postoperative complications compared to standard surgical equipment. Therefore, more high-quality investigations are needed to corroborate the initial results.

Introduction: Previously, the laparoscopic approach was not considered for obese people, because of the increased risk of operative and postoperative complications. In recent years, however, the approach has changed in favor of minimally invasive procedures that avoid laparotomy, which, in obese people, is the most common cause of complications, in the form of slower and aggravated wound healing, bleeding, and infections at the laparotomy site. In emergency situations, extreme obesity accompanied by multiple comorbidities still remains a real challenge for endoscopic surgery, the surgeon and the entire surgical and anesthesiology team. Case report: We present a case of a 61-year-old, extremely obese patient, who was admitted to hospital as an emergency case, due to prolonged vaginal bleeding and anemia. After preoperative preparation, the patient underwent surgery - laparoscopic total hysterectomy with bilateral salpingo-oophorectomy. Conclusion: Obesity is a major problem in modern society. In addition to directly affecting health, excessive body weight in a patient makes it very difficult to perform surgical procedures. The thickness of the abdominal wall and accompanying health problems are a contraindication for laparoscopic operations. In such cases, performing surgery, especially laparoscopic procedures, requires a trained team of professionals and appropriate equipment. Laparoscopic surgery is more and more present, even in the most difficult cases. In presenting this case, we aimed to demonstrate that it is possible to successfully perform total laparoscopic hysterectomy in extremely obese patients with associated health problems, even in emergency situations.
