Objective: To present a case study of a 69-year-old woman with COVID-19 who developed neurological complications due to Extracorporeal Membrane Oxygenation (ECMO) therapy and highlight the importance of daily neurological examinations and rehabilitation in the early detection and management of ECMO-related neurological complications in an isolation ICU. Design: A case report Methods: The patient received ECMO therapy, followed by neurological monitoring and rehabilitation in an isolation ICU. Daily neurological examinations were conducted to monitor the patient's neurological symptoms. Computed tomography was performed to confirm the presence of a hematoma in the left hamstring, which was identified as the cause of the neurological complication. Ultrasound-guided aspiration was immediately performed, and sciatic neuropathy predominantly involving the peroneal division was identified after aspiration. Results: Successful recovery was made possible by the early detection of neurological complications and rehabilitation in an isolation ICU. Although electrodiagnostic tests were not performed due to limited access to the isolation ICU, the appropriate intervention time could be determined through daily neurological examinations and rehabilitation, thereby minimizing neurological sequelae. Conclusions: ECMO-related neurological complications are well known, and their recognition in the ICU can be challenging. The presented case highlights the importance of daily neurological examinations and rehabilitation in the early detection and management of ECMO-related neurological complications in an isolation ICU, which can minimize neurological sequelae.

In the l950s, under the legacy of traditional agriculture, Ascaris lumbricoides, spread epidemically in the war-bitten society of Korea. Consensus on the parasite control was drafted in the Parasite Disease Prevention Act, which passed a parliamentary agreement in 1966, and established safe disposal of feces and mass chemotherapy as control strategies. Biannual stool examinations and treating infected schoolchildren were basic scheme of the control activity through which revenue could be secured for organized business. In the 27 years following 1969, a maximum of 16 million stool examinations had been done every year. Cellophane thick smear enabled the task. The infection declined remarkably in the 1970s when industrialization and green revolution proceeded. A population study of A. lumbricoides in the late 1970s helped us better understand its epidemiology. The data also settled down the understandable protest of teachers against the repeated stool examinations. In the 9 years following 1987, the target population was gradually reduced when the egg positive rate was below 0.1%. An article in the Korean Law, stipulating obligatory stool examinations, was made optional. Although the long-term Korean effort of Ascaris control was a success, the effect of mass chemotherapy was not as succinct in terms of lowering reinfection. In the period of control, Korean agricultural technology changed, and the economy grew and supplied sanitary facilities by which the vicious cycle was disconnected. Reduction of morbidity was a benefit of mass chemotherapy, which is the only control method feasible in economically difficult countries. The most important hurdle of parasite control in the 1960s was poverty of general population and limited financial resources in Korea but the society formed a consensus on the priority of intestinal helminthiasis control during the ordeal period. The national consensus in the 1960s was the critical milestone for Ascaris control in Korea. Under the social agreement, application of timely technical and research advancements in parasitology achieved the success of ascariasis elimination. The successful experience of ascariasis elimination in Korea can be a benchmark for countries where neglected tropical diseases are endemically recycled.

Purpose: This study was conducted to investigate the safety of dental imaging in pregnant women with respect to fetal health. Materials and Methods: Searches were conducted of the PubMed, Scopus, and Web of Science databases in May 2023. The inclusion criteria encompassed cross-sectional and longitudinal studies that focused on the analysis of diagnostic dental imaging in pregnant women, as well as studies utilizing phantoms to simulate imaging examinations. The exclusion criteria consisted of reviews, letters to the editor, book chapters, and abstracts from scientific conferences and seminars. Results: A total of 3,913 articles were identified. Based on a review of the titles and abstracts, 3,892 articles were excluded, leaving 21 articles remaining for full-text review. Of these, 18 were excluded, and 4 additional articles were included as cross-references. Ultimately, 7 articles underwent quantitative-qualitative analysis. Three retrospective studies were focused on pregnant women who underwent dental imaging procedures. The remaining 4 studies utilized female phantoms to simulate imaging examinations and represent the radiation doses absorbed by the uterus or thyroid. Conclusion: Few dental radiology studies have been conducted to determine the safe radiation threshold for pregnant women. Additionally, the reviewed articles did not provide numbers of dental examinations, by type, corresponding to this dose. Dental imaging examinations of pregnant women should not be restricted if clinically indicated. Ultimately, practitioners must be able to justify the examination and should adhere to the "as low as diagnostically acceptable, being indication-oriented and patient-specific" (ALADAIP) principle of radioprotection.

Non-destruction examinations are required in medical sciences and various engineering now. We wish to emulate the examinations in very simplified experiments. It is an educational program. We show a neural network analysis to predict the locations of a sound-source or a body irradiated by sound-waves in audio-region. The sound is an interest flux, and it enables to clear local-structures in a non-transparent space. However, the sound-propagation equations are not solved easily, therefore, we consider to adopt multi-layer neural-networks instead of the direct solutions. We used detected intensities and coordinates for input data and teaching data. A neural network learned them. The neural-network analysis decomposed the distance of 50cm. The resolution is rather rough; however, it is caused by the limitation of our equipments. Since there is no problem in the neural network processing, if we could revise experiments, then, progress of the resolution would be got. Thus, the proposed method functioned as an educational and simplified non-destruction examination.

We report the case of a 14-year-old girl who visited the emergency room because of suprapubic discomfort and sudden acute urinary retention. She did not have any significant medical and surgical history, and her neurological examinations were all normal. Urinary catheterization led to the passage of 500 mL urine. Abdominal ultrasonography showed a hematocolpos that was compressing the urinary bladder. Gynecologic history taking revealed that the patient has not had menarche yet. Therefore, a cruciate incision was performed and her urination became normal. As the surgical outcome after adequate hymenotomy for imperforate hymen is usually good, the diagnosis of imperforate hymen is important. However, this condition is easily missed in the clinic because the first physician visited by the patient rarely takes a detailed gynecologic history or performs appropriate physical examinations. Although rare, imperforate hymen should be considered as a cause of acute urinary retention in the adolescence period. If an adolescent girl presents with abdominal pain and voiding dysfunction, a detailed gynecologic history and appropriate physical examinations of the genital introitus should be performed.

Background: Nurses play an important role in preventive medicine because they represent the largest sector of health professionals. This role is very crucial in developing countries, which are going through rapid societal and economic changes, associated with a rising burden of cancers due to different risk factors. The current study aimed to compare health awareness between nurses and healthy women regarding preventive gynecological examinations and to answer the question - can nurses make a difference in women's health? Materials and Methods: This cross sectional research included a total of 150 women, 70 nurses and 80 healthy women, randomly selected. Data were collected in 2014 in Vlora city through a self-administered questionnaire that assessed different variables about preventive gynecological examinations. Results: Cervical screening rates were 20.3% and 41.8%, respectively, for nurses and healthy women, despite the former having a statistical significant greater knowledge of risk factors and symptoms. Conclusions: Even if the health awareness of nurse participants can be considered good, they need themselves to increase participation rates in cervical screening if they are to provide role models for health education/promotion addressing misconceptions and barriers.
