This study aimed to investigate and classify the occurrence of waterborne diseases in Florianópolis city, Santa Catarina State, Southern Brazil and to correlate these diseases with the following social-environmental indicators of the local population: type of water supply, adequate collection and sewage treatment, areas of flooding and domestic water tank cleaning. Reports of outpatients were analyzed for surveillance of waterborne diseases during the period of 2002 to 2009. Waterborne diseases were classified into four groups: Group A: diarrheal diseases; Group B: parasitological diseases; Group C: skin diseases and Group D: eye diseases. The diarrheal, parasitological and skin diseases were the most frequently reported. Waterborne diseases belonging to Group A in all sites were correlated with other waterborne diseases groups, which can be an indicator of the circulation of other waterborne diseases. Regarding the social-environmental indicators assessed, the most correlated with waterborne diseases were the origin and quality of the water supply, followed by inadequate collection and treatment of sewage, frequent flooding, and finally the lack of cleanliness of the water reservoir. The results highlight the need for policies aiming for improvement of the sanitation service in the maintenance of human, animal and environmental health.

Background: Scabies is one of the most common skin diseases in our country. It is caused by the mite Sarcoptes scabiei var hominis, which is an ecto-parasite infesting the epidermis. Scabies is highly contagious. Prevalence is high in congested or densely populated areas. Individuals with close contact with an affected person should be treated with scabicidal which is available in both oral and topical formulations. The only oral but highly effective scabicidal known to date is Ivermectin. Amongst topical preparations, Permethrin 5 % cream is the treatment of choice. Objective: To evaluate the efficacy & safety of oral Ivermectin compared to topical Permethrin in the treatment of scabies. Methodology: This prospective, non-randomized study was conducted at the out-patient department of Dermatology and Venereology of Shaheed Suhrawardy Medical College & Hospital over a period of 6 months, from August 2016 to January 2017. The study population consisted of one hundred patients having scabies, enrolled according to inclusion criteria. They were divided into two groups. group A was subjected to oral Ivermectin and the group B to Permethrin 5% cream. Patients were followed up on day 7 and 14 for assessment of efficacy and safety. Result: The mean scoring with SD in group A (Ivermectin) and group B (Permethrin) were 8.26 ± 2.22 and 7.59 ± 2.01 respectively at the time of observation. The difference between the mean score of the two group is not significant (p=0.117) the mean scoring with SD in group A and group B were 4.54 ± 2.05 and 1.64 ± 1.84 respectively at 7thdays. The difference between the mean score of the two group is significant (p<0.001). The mean scoring with SD in group A and group B were 2.68± 2.35 and .36± 1.10 respectively at 14th day difference between the mean score of the group is significant (p<0.001). Conclusion: Topical application of permethrin 5% cream is more effective and safer than oral Ivermectin in the treatment of scabies. TAJ 2020; 33(1): 41-47

Currently, one of the priority medical and social problems is the optimization of treatment methods for pyoderma associated with Streptococcus pyogenes — group A streptococcus (GAS). To date, the proportion of pyoderma, the etiological factor of which is Streptococcus pyogenes, is about 6 % of all skin diseases and is in the range from 17.9 to 43.9 % of all dermatoses. Role of the bacterial factor in the development of streptococcal pyoderma is obvious. Traditional treatment complex includes antibacterial drugs selected individually, taking into account the antibiotic sensitivity of pathognomonic bacteria, and it is not always effective. Currently implemented immunocorrection methods often do not take into account specific immunological features of the disease, the individual, and the fact that the skin performs the function of not only a mechanical barrier, but it is also an immunocompetent organ. Such an approach makes it necessary to conduct additional studies clarifying the role of factors of innate and adaptive immunity, intercellular mediators and antioxidant defense system, that allow to optimize the treatment of this pathology.

Current assessments of sustainability are based on traditional indicators and need to be adjusted. The article analyzes the factors of environmental management efficiency and shows the interdependence of ecosystems’ state and economic development on example of the Baikal natural area. The development of economic activity in the region largely dependson the ability to use the water resources of the lake Baikal, which is experiencing a significant anthropogenic load, and the basis for the regulation of natural resources are prohibitive and restrictive mechanisms that do not take into account the interests of the local population. The article proposes approaches to improving the assessment of development, taking into account the socio-economic and environmental indicators of the Baikal natural area.

Life, health and hygiene all depend on access to a plentiful supply of safe drinking water. Piped water supplies in rural Egypt are insufficient to meet the demands of the existing population. This situation is worsening due to the rapid population growth and failure of existing water supply systems. There are already areas of the country with severe piped water shortages. If corrective action is not taken soon densely populated villages will become vulnerable to outbreaks of waterborne diseases. Immediate action is needed to reverse the deterioration of water supply systems and to improve the benefits gained from capital works investments in the sector. This paper promotes the concept that sustainable water systems in rural Egypt depends on a central government and local unit partnership. Also needed are consumer bodies to determine user needs; local units to be given powers to manage the revenue and expenditure accounts; and the central government to concentrate on setting policies and guidelines, and assisting with the implementation of major capital works.

Abstract Background Streptococcus pyogenes, or Group A Strep (GAS), is not considered a typical cause of infective endocarditis (IE), but has anecdotally been observed in unexpectedly high rates in people who inject drugs (PWID) at our institution. Methods All cases of possible or definite GAS IE per Modified Duke Criteria in adults at an academic hospital between 11/15/2015 and 11/15/2020 were identified. Medical records were reviewed for demographics, comorbidities, treatment, and outcomes related to GAS IE. Literature on cases of GAS IE was reviewed. Results 18 cases of probable (11) or definite (7) GAS IE were identified; mean age was 38 years, and the population was predominantly female (56%) and Caucasian (67%), which is inconsistent with local population demographics. Sixteen cases were in people who inject drugs (PWID) (89%), 14 were also homeless, six were also living with HIV (33%), and two were also pregnant. Antibiotic regimens were variable due to polymicrobial bacteremia (39%). One patient underwent surgical valve replacement. Four patients (22%) died due to complications of infection. Literature review revealed 42 adult cases of GAS IE, only 17 of which were in PWID (24%). Conclusions The 16 cases of possible and definite GAS IE in PWID over a five-year period in a single institution reported nearly doubles the number of cases in PWID from all previous reports. This suggests a potential increase in GAS IE particularly in PWID and PLWH, which warrants further epidemiologic investigation.

The essential requirement for human life to exist is water. After to the air, the other It has in various sources such as canals, ponds, rivers, lake, streams, reservoirs and etc. human settlers on the banks of major river systems at the earliest and has need water for drinking, bathing, cooking, laundering, and many more. But with the advancement of civilization the demand of water supply grately increased and now has such a stage to come that without well organized public water supply scheme, it is not possible to move the present human life and the develop the towns. Earlier has importance on quantity. And now today importance of quality comes to be recognized gradually in the later days. In this present study, numbers of water samples were collected various water supply schemes from 20 villages of bhimavaram region, West Godavari district, Andhra Pradesh. The drinking water samples are analyze its biological quality and it was found that some of the samples in the study area are exceeds or above the standard limit or permissible limit. On over all based on biological quality few drinking water sources located in and around different areas of Bhimavaram was seriously polluted by harmful bacteria and must need few treatment methods. So that need of attention not to use of supplied water and need to give suggestions and remedial measures to concerned local authorities of various disinfection treatment technologies or control measure to make supplied water free from pathogenic Bactria. Quality Assessment of drinking water from various sources (S Malhotra, S.K., Sndhu (2015), especially bacteriological quality should be periodically planned regularly to avoid and control waterborne diseases

Previous research about the exposure of Mozart music and noise and the effects towards the feeding, growth rate and the stress level of the broilers were explored.Music has the ability to have a relaxing and antidepressant effect on humans, mammals and birds. Reports that music calms animals and improves productivity appear in commercial journals. The present study investigated the growth rate comparisons between the experimented broilers (Group A: water supply modification group; Group B: sound exposure group) and the control broilers (Group C: control group) in terms of weight and raw meat texture measured by shear force. The water supply modification group was given 12 litres of Yasin water twice per day while the sound exposure group were broadcasted with sound of Quran verses. Twenty-seven broilers were randomly selected from each group on Day 24 and weight measurement was carried out every week until the harvest day (Day 39). Group B showed a higher mean weight on Day 24 (1.441 ± 0.013 kg) than Group A and C. Significant difference in the weight on Day 39 existed for both Group A and B compared to Group C (p < 0.05). However, there was no significant (p > 0.05) difference of shear force in the same muscles (breast and drumstick raw meat) of the three groups but the shear force of the breast meat for Group A, B and C broilers was lower (p < 0.05) than that of their drumstick meat. Broadcasting the sound of the Quran verses in the coop and adding Yasin water to the broilers’ drink can be applied to improve the growth rate of broilers for producing better quality poultry.

Heat pump water heaters are increasing in popularity due to their increased energy efficiency and low environmental impact. This paper describes the experimental testing of a transcritical CO2 heat pump water heater at Queen’s University. A modified 4.5 kW Eco-Cute unit was studied. It sourced heat from a constant temperature water supply and rejected the heat to a 273 litre hot water tank through a gas-cooler. The high temperatures that occur in the gas-cooler of this unit make it ideally suited for natural convection, (i.e., thermosyphon) circulation on the potable water side. This has the potential to reduce pumping power, simplify system operation and design, and increase thermal stratification in the hot water storage tank. This configuration, however, is susceptible to the accumulation of sediments, scale and mineral deposits (i.e., fouling) in geographic regions where high mineral deposits may be present in the water supply. To counteract fouling in these cases, a passive back-flushing system was proposed to prevent the accumulation of deposits on the heat transfer surfaces of the gas-cooler. As hot water is drawn from the system, the cold “mains” supply water is directed through the gas-cooler in the reverse direction of normal operation, scouring the heat transfer surfaces and dissolving deposits of inverse-soluble salts which are a major contributor to fouling on hot heat transfer surfaces. The gas-cooler used was a specially designed unit that, although offering high performance in a compact unit, may be susceptible to the fouling and blockage of the heat transfer passages when used at thermosyphon flow rates. Experiments were conducted to evaluate the effects of the back-flush operation on heat pump performance (i.e., COP) and operation. These were conducted under controlled laboratory conditions, at a range of draw flow rates and temperatures, and are summarized in this paper.
