Diphtheria is caused by Corynebacterium species, mostly by toxin-producing Corynebacterium diphtheriae and rarely by toxin-producing strains of C. ulcerans and C. pseudotuberculosis. The most common type of diphtheria is classic respiratory diphtheria, whereby the exotoxin produced characteristicall...y causes the formation of a pseudomembrane in the upper respiratory tract and damages other organs, usually the myocardium and peripheral nerves. Acute respiratory obstruction, acute systemic toxicity, myocarditis and neurologic complications are the usual causes of death. The infection can also affect the skin (cutaneous diphtheria). More rarely, it can affect mucous membranes at other non-respiratory sites, such as genitalia and conjunctiva.
C. diphtheriae is transmitted from person to person by intimate respiratory and direct contact; in contrast, C. ulcerans and C. pseudotuberculosis are zoonotic infections, not transmitted person-to-person. The incubation period of C. diphtheriae is two to five days (range 1– 10 days). A person is infectious as long as virulent bacteria are present in respiratory secretions, usually two weeks without antibiotics, and seldom more than six weeks. In rare cases, chronic carriers may shed organisms for six months or more. Skin lesions are often chronic and infectious for longer periods. Effective antibiotic therapy (penicillin or erythromycin) promptly terminates shedding in about one or two days.

About one fourth of the world’s population is estimated to have been infected with the tuberculosis (TB) bacilli, and about 5–10% of those infected develop TB disease in their lifetime. The risk for TB disease after infection depends on several factors, the most important being the person’s im...munological status. TB preventive treatment (TPT) given to people at highest risk of progressing from TB infection to disease remains a critical element to achieve the global targets of the End TB Strategy, as reiterated by the second UN High Level Meeting on TB in 2023. Delivering TPT effectively and safely necessitates a programmatic approach to implement a comprehensive package of interventions along a cascade of care: identifying individuals at highest risk, screening for TB and ruling out TB disease, testing for TB infection, and choosing the preventive treatment option that is best suited to an individual, managing adverse events, supporting medication adherence and monitoring programmatic performance

WHO estimates that in 2015, 257 million people were living with chronic hepatitis B virus (HBV) infection worldwide, and that 900 000 died from HBV infection, mostly through the development of cirrhosis and hepatocellular carcinoma. Worldwide, the majority of persons with chronic hepatitis B infecti...on and associated deaths in adulthood acquired their infection at birth through mother-to-child perinatal transmission or in early childhood.

Sexual abuse perpetrated against children is one of the most significant crises of our time. Child sexual abuse is a significant risk factor for children, in common with other forms of child maltreatment. Sexual abuse can have severe short- and long-term consequences on the physical, mental, social,... emotional and economic well-being of children, families and communities. In emergencies, the threat of all forms of child abuse and gender-based violence (GBV), including child sexual abuse, is acute and widespread.

There is a growing interest in the potential contribution the private sector can make towards increasing access to antiretroviral therapy (ART) in low‐ and middle‐income settings. This article describes a public–private partnership ...that was developed to expand HIV care capacity in Yangon, Myanmar. The partnership was between private sector general practitioners (GPs) and a community‐based non‐governmental organization (International HIV/AIDS Alliance).

In view of the ongoing political, peace and reconciliation, administrative and economic reforms as well as plans to establish the United Nations Development Assistance Framework (UNDAF) in 2018, WFP extended the current Protracted Relief and Recovery Operation (PRRO 200299), launched in January 2...013, by two years to include 2016 and 2017, with approved budget USD 343 million. To echo this extension and provide a more appropriate response to the country's rapid and multi-pronged transition, WFP adopted a transition strategy with gradually reduced emphasis on humanitarian assistance and greater focus on early recovery and development interventions. WFP's strategic engagement in-country was driven by the overarching goal to assist Myanmar to achieve the national Zero Hunger Challenge by 2025, and was guided by three priorities: emergency preparedness and response; nutrition; and provision of social safety nets.

Topics in Antiviral Medicine 25 Issue 2 May/June 2017
The guide is organized into the major types of toxicities, the associated symp-toms, possible offending medications, and the suggested nursing assessments and interventions. Some symptoms (e.g. nausea) may be associated with a num-ber of underlying causes and may be mild, or a symptom of... a more serious medical situation requiring urgent attention. The pathophysiology for medica-tion-related fatigue and hypersalivation are unclear and these symptoms are not grouped under a specific type of toxicity. Additional information (comments) are provided for each toxicity to highlight relevant clinical information that may assist in management of side effects. Medications more strongly associated with the side effect appear in bold text. The appendices include tools nurses can use to more thoroughly assess patient complaints of pain, depression and neuropathy.

It summarizes guidance on how to manage – and when to refer – children and adolescents presenting with common complaints and conditions. It includes information to enable primary health care providers to coordinate the continued care of children and adolescents with long-term conditions and dise...ases managed by specialists. Preventive and promotive measures from the newborn period to adolescence include advice on the timing and content of well-child visits, the promotion of early childhood development and health messages for adolescents.
This Pocket Book aims to improve the diagnosis and management of common conditions in children and adolescents that can be managed at the outpatient level. It helps to improve the use of laboratory and other diagnostic measures and the rational use of essential drugs and equipment.

Chagas disease, also known as American trypanosomiasis, is a neglected tropical disease transmitted by triatomine insects, first identified in 1909. Chagas disease affects approximately 6–7 million peop...le globally and is highly prevalent in Latin America where most cases are reported. However, there is increasing evidence that Chagas disease is now an important public health issue outside the “classical” endemic countries due to population migration. Our understanding of Chagas disease, including its pathologies and factors relating to progression, remains to date limited, and is also challenged by lack of diagnosis and highly effective treatment. This systematic review aims to describe studies with Chagas patients receiving antiparasitic treatment. Databases were searched for relevant studies published after 1997, and the results of these searches were screened.

This was a Phase 3, multi-center, randomized, open-label, parallel-group, active control study where 273 male and female patients with first stage Trypanosoma brucei gambiense HAT were treated at six sites: one trypanosomiasis reference center in Angola, one hospital in South Sudan, and four hospita...ls in the Democratic Republic of the Congo between August 2005 and September 2009 to support the registration of pafuramidine for treatment of first stage HAT in collaboration with the United States Food and Drug Administration. Patients were treated with either 100 mg of pafuramidine orally twice a day for 10 days or 4 mg/kg pentamidine intramuscularly once daily for 7 days to assess the efficacy and safety of pafuramidine versus pentamidine. Pregnant and lactating women as well as adolescents were included.

PLoS Negl Trop Dis 15(8): e0009697. Chagas disease (CD), caused by the parasite Trypanosoma cruzi, affects ~6–7 million people worldwide. Significant limitations still exist in our understanding of CD. Harnessing individual participant data (IPD) from studies could support more in-depth analyses t...o address the many outstanding research questions. This systematic review aims to describe the characteristics and treatment practices of clinical studies in CD and assess the breadth and availability of research data for the potential establishment of a data-sharing platform.
