Morbidity and mortality associated with tobacco use re-main a major public health problem. Unfortunately, mo-dern pharmacotherapy for smoking cessation have limited effectiveness, and most smokers repeatedly stop smoking. The better understanding of the neurobiological and neu-rophysiological mechanisms that contribute to the relapse of smoking is necessary for new drugs for the nicotine ad-diction treatment. The review examined preclinical studies aimed at identifying neurotransmitter and neuromodula-tory systems that provide a relapse of nicotine consump-tion. In preclinical studies, the efficacy of regulating extra-cellular neurotransmitters or neurotransmitter receptor activity using antagonists or receptor agonists (both full and partial) has been demonstrated. In particular, it was shown that a drug that selectively binds to acetylcholine receptors containing three α4- and two β2-subunits reduc-es the search for nicotine in rats. It was shown that new pharmacological approaches to reduce the craving for ni-cotine in animal models can be used in the future to re-duce the risks of relapse of nicotine addiction in smokers.

AbstractDuring the colonial period sexually transmitted infections (STIs) came to be recognised as a major public health problem in African cities. Thus, STI control and urban modernisation became deeply entangled as authorities redrew spatial and social boundaries to manage populations and their cross-cultural interaction. Public health measures, urban planning and policing were part of a coordinated effort to neutralise the potential impact of rapidly growing African urban migration on the Belgian Congo’s ‘model’ capital Leopoldville. While STI control was facilitated by new drugs (arsenicals, sulfonamides and antibiotics) to treat syphilis, chancroid, gonorrhoea and chlamydia (bacterial STIs), the effects of the 1929 economic crisis and urban social change illustrated the limits of colonial authority. Redesigning urban spaces and repressive measures to curb polygyny and prostitution operated in a parallel fashion with the expansion of health coverage, new treatments and awareness campaigns. To gain a better understanding of the evolution of STI incidence among African urban populations during the colonial period between 1910 and 1960, extensive archival records and secondary literature were consulted to assess the interplay between improved screening, diagnostic and therapeutic methods with demographic and social change. They show that STI rates, probably peaked during the pre-1929 period and apart from a short period in the early 1930s associated with mass screening, declined until becoming residual in the 1950s. Reflecting upon sanitary interventions and their broader dimensions, the article analyses the evolution of treatment regimes and their impact in the changing urban organisation and environment of the colony’s capital.

Tuberculosis remains endemic and major public-health problem in most part of the world. Despite the reduction in the prevalence of the tuberculosis and the advent of new drugs for tuberculosis, the incidence of extra pulmonary tuberculosis continues to increase at world level.

The high mortality rate among drug users, which is partly due to the HIV epidemic and partly due to drug-related accidental deaths and suicides, presents a major public health problem. Knowing more about prevalence, incidence, and risk factors is important for the development of rational preventive and therapeutic programs. This article attempts to give an overview of studies of the relations between substance abuse, suicidal ideation, suicide, and drug-related death. Research in this field is hampered by the absence of clear definitions, and results of studies are rarely comparable. There is, however, consensus about suicidal ideation being a risk factor for suicide attempts and suicide. Suicidal ideation is also a predictor of suicide, especially among drug users. It is correlated with an absence of family support, with the severity of the psychosocial dysfunctioning, and with multi-drug abuse, but also with requests for treatment. Every clinical examination of a drug user, not only of those who are depressed, should address the possible presence of suicidal ideation, as well as its intensity and duration.

The emergence in China of 2019 of severe acute respiratory syndrome coronavirus2 (SARS-CoV-2) previously provisionally names 2019-nCoV disease (COVID19) caused major global outbreak and is a major public health problem. On 30 January 2020, the WHO declared COVID19 to be the sixth international public health emergency. This present pandemic has engrossed the globe with a high rate of mortality. As a front line practitioner, physiotherapists are expected to be getting in direct contact with patients infected with the virus. That’s why it is necessary for understanding the many aspects of their role in the identification, contains, reduces and treats the symptoms of this disease. The main presentation is the involvement of respiratory system with symptoms like fever, cough, sore throat, sneezing and characteristics of pneumonia leads to ARDS(Acute respiratory distress syndrome) also land up in multiorgan dysfunction syndrome. This text describes and suggests physiotherapy management of acute COVID-19 patients. It also includes recommendations and guidelines for physiotherapy planning and management. It also covers the guidelines regarding personal care and equipment used for treatment which can be used in the treatment of acute adult patients with suspected or confirmed COVID-19.

We aimed to estimate the nationwide prevalence of anaemia among adolescents in Egypt and to study possible risk factors. A cross-sectional approach was used. Blood samples were collected from 1980 adolescents for haemoglobin estimation. The overall prevalence of anaemia was 46.6%, most of which was mild or moderate, with severe cases in less than 1.0% of the sample. Gender difference was almost nonexistent. A significant inverse relationship was observed between the level of anaemia and age [especially among boys], socioeconomic level and educational level. Anaemia was more prevalent in rural areas and in Upper [southern] Egypt. Anaemia is a major public health problem among Egyptian adolescents and wide-scale public health education is warranted.

Introduction: Multidrug-resistant typhoid fever (MDRTF) is defined as typhoid fever caused by Salmonella enterica serovar Typhi strains (S. Typhi), which are resistant to the first-line recommended drugs for treatment such as chloramphenicol, ampicillin and trimethoprim-sulfamethoxazole. Since the mid-1980s, MDRTF has caused outbreaks in several countries in the developing world, resulting in increased morbidity and mortality, especially in affected children below five years of age and those who are malnourished. Methodology: Two methods were used to gather the information presented in this article. First PubMed was searched for English language references to published relevant articles. Secondly, chapters on typhoid fever in standard textbooks of paediatric infectious diseases and preventive and social medicine were reviewed. Results: Although there are no pathognomonic clinical features of MDRTF at the onset of the illness, high fever ( > 104°F), toxaemia, abdominal distension, abdominal tenderness, hepatomegaly and splenomegaly are often reported. The gold standard for the diagnosis of MDRTF is bacterial isolation of the organism in blood cultures. Ciprofloxacin and ceftriaxone are the drugs most commonly used for treatment of MDRTF and produce good clinical results. Conclusion: MDRTF remains a major public health problem, particularly in developing countries. Mass immunization in endemic areas with either the oral live attenuated Typhi 21a or the injectable unconjugated Vi typhoid vaccine, rational use of antibiotics, improvement in public sanitation facilities, availability of clean drinking water, promotion of safe food handling practices and public health education are vital in the prevention of MDRTF.

Two cases of New World cutaneous leishmaniasis acquired by Russian tourists in Peru and possibly in Bolivia are presented. L. viannia ( L.braziliensis complex) was identified in Liverpool School of Tropical medicine in the patient travelled to Bolivia. The present study aimed to investigate Balsamum peruvianum one of the product of folk medicine of Indians of Amazon region against local species of Leishmania resulted in healing the ulcers. Leishmaniasis is a major public health problem, and the alarming spread of parasite resistance has increased the importance of discovering new therapeutic products.
