This chapter covers cancer of the oral cavity and the oropharynx, which includes the base of the tongue, soft palate, tonsils, and back and side walls of the throat. Many important risk factors for oral and oropharyngeal cancer have been identified, and in 2007 the World Health Organization determined there was sufficient evidence to include human papilloma virus (HPV) type 16 as a cause of these cancers. Tobacco and alcohol remain important modifiable risk factors, but the increasing incidence of HPV-associated tumors is now evident. While these tumors are more amenable to treatment than HPV-negative tumors, they are still a source of considerable morbidity and mortality. Moreover, the lack of a precursor lesion and limited data on efficacy of the HPV vaccine in preventing oral HPV infection are barriers to primary and secondary prevention efforts. Dietary patterns high in fruits and vegetables and low in meats may confer some protection.

Abstract A lesser known reason of epidemic proportion of oral cancer in India is the rampant use of Areca nut chewing. Just like tobacco, areca nut or betel nut is a psychostimulant, an addictive substance and a carcinogen. The cancer causing properties of areca nut have been well-reported in animal, human and epidemiologic studies. The World Health Organization and International Agency for Research on cancer classified areca nut as a Group 1 human carcinogens with sufficient evidence of increased risk of submucus fibrosis (precancerous oral lesion) and cancers of the oral cavity, pharynx, and esophagus. This was based upon several studies from India, Bangladesh, Pakistan and Taiwan. Cancers caused by betel nut chewing also shows a strong dose–response relationship for frequency and duration of chewing. It is postulated that areca nut-specific N-nitroso compounds converted from alkaloids are responsible for oral and pharyngeal cancer. There are several other reports that have linked areca nut chewing (with or without tobacco) with hepatocellular carcinoma, cholangiocarcinoma, cancers of the larynx, stomach, lung and cervix in humans.

Oral and pharyngeal cancer is estimated by World Health Organization (WHO) to be the eighth most common cancer worldwide with signi�cant regional variation with increasing and decreasing incidence trend. The aim of the study was to evaluate the oral cancer epidemiological trend, incidence and mortality in Central and East Europe (CEE), and to compare the incidence of oral cancer with other regions from the world. The analyzed data was from NORDCAN and GLOBOCAN, using ASR (age- standardize rate) incidence and mortality overall and by sexes. The incidence of oral and pharyngeal cancer is higher in CEE than the global incidence. This is in accord with specific mortality from oral and pharyngeal cancer that is higher in CEE than the regions other submitted to the current evaluation. The incidence of oral cancer is very high at man, especially in Hungary, which is the most affected from oral cancer from CEE.

Abstract Introduction Cooking- and cookstove-related burns (CSBs) comprise a large proportion of burn injuries globally. A cookstove is any apparatus that provides heat and is used for cooking (e.g., three-stone fire, traditional or improved cookstove). There are limited data on patterns of cooking behaviors and CSBs to inform prevention initiatives and advocacy. We aimed to describe the epidemiology, risk factors and outcomes of cooking-related burns and CSBs, specifically. Methods Patients with cooking and non-cooking related burns from 2018 to 2020 were identified in the World Health Organization (WHO) Global Burn Registry (GBR). Patient demographics, cooking arrangement, injury characteristics [mechanism, total body surface area (TBSA), revised Baux score] and outcomes were described. Differences in proportions and medians were compared. Bivariate regression was performed to identify risk factors associated with occurrence of CSB. Results GBR contained data of 6,965 burn-injured patients from 17 countries; 88% were from middle-income countries. One quarter of burn injuries (1,723 burns) were cooking-related. More than half of cooking-related burns (55%) occurred in females. Median age for cooking-related burns was 11 years (IQR 2–35). Of cooking-related burns, 22% were cookstove-related burns (CSBs; 311 burns). The most common mechanism in CSB was flame (87%), whereas the most common mechanism in other cooking burns was scald (62%). Patients with CSBs were more often female (65% vs 53%; p< 0.001) and much older than patients with other cooking burns (32 years, IQR 22–47 vs 5 years, IQR 2–30). CSBs were significantly larger in TBSA size (30%, IQR 15–45% vs 15%, IQR 10–25%; p< 0.001), had higher revised Baux scores (70, IQR 46–95 vs 28, IQR 10–25; p< 0.001) and more often resulted in death (41 vs 11%; p< 0.001) than other cooking burns (Table1). Patients with CSBs were more likely to be burned by fires (OR 4.74; 95% CI 2.99–7.54) and explosions (OR 2.91, 95% CI 2.03–4.18) than other cooking injuries. Kerosene had the highest odds of CSB than all other cooking fuels (OR 2.37, 95% CI 1.52–3.69). Conclusions Cooking-related burns are common and have different epidemiology than CSBs, specifically (e.g., more often female, older, larger burn size, higher mortality). CSBs were more likely caused by structural factors (e.g., explosion, fire) than behavioral factors (e.g., accidental movements) when compared to other cooking burns.

Abstract The World Health Organization set a target of a 15% relative reduction in the prevalence of insufficient physical activity (IPA) by 2025 among adolescents and adults globally. In Bangladesh, there are no national estimates of the prevalence of IPA among adolescents. The aim of this study was to estimate the prevalence of and risk factors associated with IPA among adolescent girls and boys. Data for 4865 adolescent girls and 4907 adolescent boys, collected as a part of a National Nutrition Surveillance in 2018–19, were analysed for this study. A modified version of the Global Physical Activity Questionnaire (GPAQ) was used to collect physical activity data. The World Health Organization recommended cut-off points were used to estimate the prevalence of IPA. Bivariate and multivariable logistic regression was performed to identify factors associated with IPA. Prevalences of IPA among adolescent girls and boys were 50.3% and 29.0%, respectively, and the prevalence was significantly higher among early adolescents (10–14 years) than late adolescents (15–19 years) among both boys and girls. The IPA prevalence was highest among adolescents living in non-slum urban areas (girls: 77.7%; boys: 64.1%). For both boys and girls, younger age, non-slum urban residence, higher paternal education and increased television viewing time were significantly associated with IPA. Additionally, residing in slums was significantly associated with IPA only among the boys. Higher maternal education was associated with IPA only among the girls. This study identified several modifiable risk factors associated with IPA among adolescent boys and girls in Bangladesh. These factors should be addressed through comprehensive public health interventions to promote physical activity among adolescent girls and boys.

Urinary schistosomiasis is considered a major public health parasitic disease in African communities. Prior to this study, Nsugbe community was not considered endemic for the disease and as such was not involved in Praziquantel-Preventive Chemotherapy (PC). Longitudinal study of 281 consented pupils aged 5-16 years was carried out with aim of determining the status of urinary schistosomiasis. Urinalysis laboratory test strip, urine filtration technique and syndromic diagnosis were used for the confirmation of the presence of haematuria in urine samples, identification of Schistosoma haematobium ova and the confirmation of female genital schistosomiasis (FGS), respectively. Risk factors for urinary schistosomiasis infection were determined using pre-tested structured questionnaire. Data were analyzed using Minitab 17 software and intensity of infection categorized following World Health Organization (WHO) recommendations. Of the 281 pupils, 117 (42%) were males and 164 (58%) were females with mean age of 9 years. At baseline, an overall prevalence of 0.4% (1/281) which was of light intensity was established. At follow-up, an overall prevalence of 2.1% (6/281) which was of both light (16.7%) and heavy infection (83.3%) was established. The result of the clinical examination showed eggs of S. haematobium in and around the vaginal area indicating FGS of a female pupil aged 12 years. This was treated. Identified risk factors for S. haematobium infection in the community include water-contact activities, ignorance, source of water supply among others. The study revealed the need for an all inclusive mass administration of Praziquantel-PC in the study community for effective control and possible elimination.

OBJECTIVES: To determine the prevalence and associated risk factors of diabetes mellitus (DM) among the adult population in Bisha province, Saudi Arabia.METHODS: A cross sectional study was conducted during December, 2015 using the World Health Organization STEPS wise approach for data collection. Blood glucose level and anthropometric measurements of blood pressure, height, weight, and waist circumference were performed per standard methods.  Logistic regression analysis was used to assess the prevalence and risk of diabetes.RESULTS: Of 542 adult individuals included in the study, 13.3% (72) had diabetes, of which 8.1% were previously diagnosed and 5.2% represented new cases. The proportions of DM were 14.7% for men and 10.8% for women. Diabetes was significantly higher among married compared to unmarried individuals (19.3% vs 5.5 %; p<0.001) and among individuals aged ≥40 years old compared to those <40 years (31.3% vs 9.3%; p<0.001). The risk of diabetes was significantly increased with older age (Odds Ratio=4.470; 95% CI 2.264-7.614), married individuals (OR=4.097; 95% CI 2.188-7.672), weight/obesity (OR=2.827; 95% CI 1.567-5.072), hypertension (OR=4.383; 95% CI 2.085-9.214) and having a job (OR=2.327; 95% CI 1.347-4.02). The independent risk factors predicted diabetes were hypertension (Adjusted OR=2.897; 95% CI 1.269-66.13) and job patterns (Adjusted OR=2.793; 95% CI 1.064-7.329).CONCLUSION: Different risk factors alarming diabetes among adult population in Bisha province were detected.  Strategies aimed to improving a healthy lifestyle are necessary to reduce the burden of the disease.

On March 11, 2020, the World Health Organization (WHO) released a statement characterizing COVID-19 as a pandemic that has, as of October 2020, caused almost 36 million confirmed global cases and over 1 million deaths. One of the long-term complications suggested by researchers is fibrosis. It has been hypothesized that the combination of ongoing pulmonary injury caused by COVID-19 and the inability to promptly repair damage results in interstitial matrix widening and eventual compression and destruction of alveoli and capillaries. Here we focus on pathogenesis, risk factors, different infectious causes of fibrosis along with COVID-19, and potential treatment options that might reduce its effects. Key words: COVID-19, pulmonary fibrosis, mechanism, treatment

There is a scarcity of data regarding coronavirus disease 2019 (COVID-19) infection in children from southeast and south Asia. This study aims to identify risk factors for severe COVID-19 disease among children in the region. This is an observational study of children with COVID-19 infection in hospitals contributing data to the Pediatric Acute and Critical Care COVID-19 Registry of Asia. Laboratory-confirmed COVID-19 cases were included in this registry. The primary outcome was severity of COVID-19 infection as defined by the World Health Organization (WHO) (mild, moderate, severe, or critical). Epidemiology, clinical and laboratory features, and outcomes of children with COVID-19 are described. Univariate and multivariable logistic regression models were used to identify risk factors for severe/critical disease. A total of 260 COVID-19 cases from eight hospitals across seven countries (China, Japan, Singapore, Malaysia, Indonesia, India, and Pakistan) were included. The common clinical manifestations were similar across countries: fever (64%), cough (39%), and coryza (23%). Approximately 40% of children were asymptomatic, and overall mortality was 2.3%, with all deaths reported from India and Pakistan. Using the multivariable model, the infant age group, presence of comorbidities, and cough on presentation were associated with severe/critical COVID-19. This epidemiological study of pediatric COVID-19 infection demonstrated similar clinical presentations of COVID-19 in children across Asia. Risk factors for severe disease in children were age younger than 12 months, presence of comorbidities, and cough at presentation. Further studies are needed to determine whether differences in mortality are the result of genetic factors, cultural practices, or environmental exposures.

Objectives: Latent TB infection (LTBI) affects 25% of the world’s population. As long as this reservoir exists, the elimination of TB will not be feasible. The Assembly of the World Health Organization adopted the “Global End TB” strategy for the elimination of TB in 2014. The objective of this review is to present strategies for risk groups that are candidates for the detection and treatment of LTBI. Material and method: There is sufficient evidence of screening in: immunocompromised people (HIV-infected, biological therapies, alternative renal therapy, organ transplantation), recent immigrants, inmates in prison, people injecting drugs and homeless people, and workers from at-risk settings. Tests to diagnose LTBI include tuberculin skin test (TST) and gamma release assay interferon (IGRA). There is no reference test and the choice of one or the other will depend on logistical considerations, such as avoiding injection (TST) or not needing a second visit (IGRA). Treatment of LTBI is based on the use of isoniazide and rifampicin in short period of 3 or 4 months, using associations of rifampicin and isoniazide or rifampicin alone. Discussion: Given the estimated high prevalence of LTBI, renewed efforts are required to reduce the number of people with LTBI that includes a registration and monitoring system to observer progress, increased testing, and the use of short treatment guidelines.

In December 2019, the Chinese government alerted the world to a dangerous virus that spread rapidly in communities. In fact, another acute respiratory syndrome occurred in Wuhan, China, and then spread rapidly to other parts of the world. The World Health Organization (WHO) refers to this virus as nCoV-2019, where n stands for “new” and CoV stands for “coronavirus”. In general, the virus (COVID-19) is similar to acute respiratory syndrome (MERS-CoV), but they are by no means identical
