Health implications to the staff incharged was studied by measuring mass density (N) of two types of particulate matter (PM1.0 and PM10.0) concentration produced during laser paint removal process over three different types of car coated substrate samples A, B and C. The lowest PM1.0 and PM10.0 concentrations detected for those substrate samples during 10 minute laser irradiation were 0.693 mg/m3 and 1.586 mg/m3, which was far exceed compared to the recommendation suggested by World Health Organization (WHO). However, laser paint removal techniques was considered safe compared than chemical paint stripping technique if smooth air ventilation in workplace was properly set-up and inhalation to PM1.0 and PM10.0 was greatly prevented by using protective mask.

This report is an overview of enterovirus (EV) detection in Tunisian polio-suspected paralytic cases (acute flaccid paralysis (AFP) cases), healthy contacts and patients with primary immunodeficiencies (PID) during an 11-year period. A total of 2735 clinical samples were analyzed for EV isolation and type identification, according to the recommended protocols of the World Health Organization. Three poliovirus (PV) serotypes and 28 different nonpolio enteroviruses (NPEVs) were detected. The NPEV detection rate was 4.3%, 2.8% and 12.4% in AFP cases, healthy contacts and PID patients, respectively. The predominant species was EV-B, and the circulation of viruses from species EV-A was noted since 2011. All PVs detected were of Sabin origin. The PV detection rate was higher in PID patients compared to AFP cases and contacts (6.8%, 1.5% and 1.3% respectively). PV2 was not detected since 2015. Using nucleotide sequencing of the entire VP1 region, 61 strains were characterized as Sabin-like. Among them, six strains of types 1 and 3 PV were identified as pre-vaccine-derived polioviruses (VDPVs). Five type 2 PV, four strains belonging to type 1 PV and two strains belonging to type 3 PV, were classified as iVDPVs. The data presented provide a comprehensive picture of EVs circulating in Tunisia over an 11-year period, reveal changes in their epidemiology as compared to previous studies and highlight the need to set up a warning system to avoid unnoticed PVs.

Background: Male medical circumcision (MMC) has been shown to reduce the risk of HIV transmission in circumcised men by up to 60%. Following recommendations from the World Health Organization, South Africa adopted MMC as a preventative strategy against HIV in 2010 and set up circumcision camps across the country. Concerns have been raised about condom avoidance following MMC because of a mistaken belief about the benefits of MMC.Aim and setting: The aim of this study was to describe the profile and knowledge about HIV and circumcision amongst men presenting for MMC in an urban area in KwaZulu-Natal.Methods: This was a cross-sectional descriptive study of 394 clients over the age of 18 years who presented to two MMC sites in Durban between November 2012 and March 2013. A validated questionnaire was used to collect data.Results: The mean age of clients presenting for MMC was 28 years. Most clients were black, single, unemployed and sexually active. The majority presented for MMC because they believed that MMC would reduce their risk of acquiring HIV infection. Knowledge about HIV transmission was very good and 86.3% of clients were aware that risky sexual behaviour suchas condom avoidance could reverse the benefits of MMC.Conclusion: The knowledge of HIV and benefits of MMC was very good amongst those presenting for MMC. However as MMC is primarily a preventative strategy, innovative methods to promote MMC prior to first sexual encounter need to be explored. Further research is needed to determine whether the benefits of MMC on the reduction of HIV transmission aresustained in routine practice. [Full text article to follow]

The annual military bill is now approaching 450 billion US dollars, while official development aid accounts for less than 5 per cent of this figure. Four examples: 1. The military expenditure of only half a day would suffice to finance the whole malaria eradication programme of the World Health Organization, and less would be needed to conquer river-blindness, which is still the scourge of millions. 2. A modern tank costs about one million dollars; that amount could improve storage facilities for 100,000 tons of rice and thus save 4000 tons or more annually; one person can live on just over a pound of rice a day. The same sum of money could provide 1000 classrooms for 30,000 children. 3. For the price of one jet fighter (20 million dollars) one could set up about 40,000 village pharmacies. 4. One-half of one per cent of one year's world military expenditure would pay for all the farm equipment needed to increase food production and approach self-sufficiency in food-deficit low-income countries by 1990.

Objective: Antibiotics are the almost usually specified or authorized medication in hospitals, and antibiotics were found to be the almost bothersome classes of drugs providing or endowing to adverse drug reactions (ADRs). Therefore, the present study was conducted to check or regulate the precautions (ADRs) of antibiotics usually specified or authorized in the pediatrics unit. Methods: A potential, experimental, non-interventionist study was conducted or executed in the Department of Pediatrics for a time of 6 months to analyze the ADRs reported spontaneously from the hospital using patient statistics, objective and medication information, data of ADRs, onset time, causal drug details, outcome, and severity. Results: Among 72 ADRs observed, beta-lactams and quinolones were set up to be contributing the highest number of ADRs. The duct or abdominal system was the almost commonly affected organ, followed by respiratory system and the cardiovascular system. The assessment by the World Health Organization causation estimation scale demonstrated that 5.56% ADRs were certain, 55.56% were possible, 30.56% were probable, and 8.33% were unlikely. Conclusion: Thus, the pattern of ADRs occurring in the pediatric population was observed and assessed. Early recognition and management of ADRs are essential to reduce the burden of ADRs

The International Health Conference, convened by the United Nations in New York in the summer of 1946, adopted a Constitution for a World Health Organization. It set up an Interim Commission of persons designated by eighteen named states to prepare for the First World Health Assembly and to carry on tasks inherited from previous international organizations. Unexpected delays in ratifications of the Constitution obliged the Interim Commission to operate for two years. WHO has thus been free to shape its destiny only from the time of the First World Health Assembly in the summer of 1948; it began its work formally as of September 1, 1948. The activities from 1946 to 1948 were largely determined by heritages from earner organizations; these, indeed, dominated the first program of WHO. The intervening three years have witnessed new trends, which some observers applaud and others view with doubt, if not alarm. It may be fruitful at this time to record some of these trends, to note the pressures which caused them and their implications for WHO's program and work-plan.

The world health organization declared the outbreak of Corona virus as a public health emergency of international concern on 30th January 2020. The disease is transmitted by inhalation or contact with infected droplets and the incubation period ranges from 2 to 14 days. This mode of transmission has led to a concern for dentists worldwide. Due to the characteristics of dental settings, the risk of cross infection can be high between patients and dental practitioners. Various modifications in treatment options have been investigated to reduce the release of aerosols and minimize patient and dentist exposure. These modifications in the dental set up are incorporated to protect the practitioner and the patient from cross contamination. One such treatment modality in reducing aerosol production is the use of Ozone. Ozone is an allotropic form of oxygen and has been used successfully in the treatment of various diseases for over a hundred years. It has a high oxidation potential and is 1.5 times greater than chlorine when it is used as an antimicrobial agent. It has also shown to stimulate remineralization and has hence led to its increasing popularity and demand in the dental field. Its unique properties include analgesic, antimicrobial and antihypnotic actions. Its atraumatic, painless, non-invasive, and relative absence of discomfort and side effects has led to its use in dentistry with increased patient’s acceptability and compliance thus making it an ideal choice for various treatment options in dentistry which would eventually lead to reduced aerosol exposure. This review is an attempt to highlight various treatment modalities of Ozone therapy during post Covid-19 scenario in dental practices and its possible clinical applications in future.

BACKGROUND For the World Health Organization, electronic health (eHealth) is seen as an effective way to improve therapeutic practices and disease prevention in health. Digital tools lead to major changes in the field of mental medicine, but specific analyses are required to understand and accompany these changes. OBJECTIVE Our objective was to highlight the positions of the different stakeholders of the mental health care system on eHealth services and tools, as well as to establish professional and user group profiles of these positions and the uses of these services. METHODS In order to acquire the opinions and expectations of different categories of people, we carried out a qualitative study based on 10 focus groups (n=70, from 3-12 people per group) composed of: general practitioners, psychiatrists, psychologists, social workers, occupational therapists, nurses, caregivers, mental health services users, user representatives, and the general public. The analyses of focus group discussions were performed independently by four investigators through a common analysis grid. The constant comparative method was adopted within this framework. RESULTS The interviewees expressed different problems that new technologies engender in the field of mental health. What was previously strictly under the jurisdiction of physicians now tends to be fragmented and distributed over different groups and locations. New technologies reposition care in the field of domestic, rather than therapeutic, activities, and thus the conception of care as an autonomous activity in the subject’s life is questioned. The ideal of social autonomy through technology is part of the new logic of health democracy and empowerment, which is linked to a strong, contemporary aspiration to perform. Participants emphasized that there was the potential risk of a decrease in autonomy for the digitally engaged patient, while personal empowerment could become a set of obligations. CONCLUSIONS This qualitative research highlights the heterogeneity of opinions among the groups and within each group. It suggests that opinions on electronic mental health devices are still far from being stabilized, and that a change management process should be set up to both regulate the development and facilitate the use of these tools.

Malaria, a disease which was under control in the beginning of Juscelino Kubitschek government, became the most important endemic disease in 1958, when Brazil made a commitment with the World Health Organization to convert its control programs into eradication programs. For this purpose a Malaria Control and Eradication Group was set up under the leadership of the malaria specialist Mário Pinotti. Malaria would become an important bargaining chip in the context of the development policies of Kubitschek. This article focuses on path of the Malaria Control and Eradication Working Group in Brazil, in its varying relationships with the arguments and guidelines established at international level

Educational institutions (schools, colleges, and universities) in India are currently based only on traditional methods of learning, that is, they follow the traditional set up of face-to-face lectures in a classroom. Although many academic units have also started blended learning, still a lot of them are stuck with old procedures. The sudden outbreak of a deadly disease called Covid-19 caused by a Corona Virus (SARS-CoV-2) shook the entire world. The World Health Organization declared it as a pandemic. This situation challenged the education system across the world and forced educators to shift to an online mode of teaching overnight. Many academic institutions that were earlier reluctant to change their traditional pedagogical approach had no option but to shift entirely to online teaching–learning. The article includes the importance of online learning and Strengths, Weaknesses, Opportunities, & Challenges (SWOC) analysis of e-learning modes in the time of crisis. This article also put some light on the growth of EdTech Start-ups during the time of pandemic and natural disasters and includes suggestions for academic institutions of how to deal with challenges associated with online learning.
