Chromoblastomycosis (CMB) is a chronic fungal infection of the skin and the subcutaneous tissue caused by a transcutaneous traumatic inoculation of a specific group of dematiaceous fungi occurring mainly in tropical and subtropical zones worldwide. If not diagnosed at early stages, patients with CBM... require long term therapy with systemic antifungals, sometimes associated with physical methods. Unlike other neglected endemic mycoses, comparative clinical trials have not been performed for this disease. Nowadays, therapy is based on a few open trials and on expert opinion. Itraconazole either as monotherapy or associated with other drugs, or with physical methods, is widely used. Recently, photodynamic therapy has been successfully employed in combination with antifungals in patients presenting with CBM. In the present revision the most used therapeutic options against CBM are reviewed as well as the several factors that may have impact on the patient's outcome.

Buruli ulcer is a chronic, progressive skin disease caused by infection with Mycobacterium ulcerans. It is currently considered to be one of the neglected tropical diseases; less common than tuberculosis but more common than leprosy. The initial lesion is a painless subcutaneous nodule, usually less... than 5 cm diameter and adherent to skin. The nodule typically breaks down centrally after days to weeks forming an ulcer with undermined edges. Thus, the external appearance of the ulcer underestimates the true size of the affected area. The patient remains well and there is no pain unless secondary bacterial infection occurs. Other forms of M. ulcerans disease include a firm plaque lesions that behaves in the same way as the nodule or an oedematous lesion that is more aggressive and extends rapidly resulting in a very large ulcer.
Any age group can be affected by Buruli ulcer diseases, but the incidence peaks at 5 to 15 years. Ulcers are most frequently on the limbs but can be on the trunk or head, sometimes with catastrophic consequences such as loss of sight or loss of breast or genital tissue. Healing close to a joint can result in contracture, and sometimes there is so much tissue destruction on a limb that amputation is unavoidable. Occasionally osteomyelitis occurs in bone adjacent to a skin lesion but involvement of other organs is rare. Disseminated disease with HIV has been reported.

Buruli ulcer (BU) is a bacterial skin infection that is caused by Mycobacterium ulcerans and mainly affects people who reside in the rural areas of Africa and in suburban and beach resort communities in Australia.
Injury to the skin and underlying tissues from acute exposure to
a large external dose of radiation is referred to as cutaneous
radiation injury (CRI). Acute radiation syndrome (ARS) 1 will
usually be accompanied by some skin damage; however, CRI
can ...occur without symptoms of ARS. This is especially true with
acute exposures to beta radiation or low-energy x-rays, because
beta radiation and low-energy x-rays are less penetrating and less
likely to damage internal organs than gamma radiation is. CRI can
occur with radiation doses as low as 2 Gray (Gy) or 200 rads 2 and
the severity of CRI symptoms will increase with increasing doses.
Most cases of CRI have occurred when people inadvertently came
in contact with unsecured radiation sources from food irradiators,
radiotherapy equipment, or well depth gauges. In addition, cases of
CRI have occurred in people who were overexposed to x-radiation
from fluoroscopy units.

Mothers and healthcare workers who support them have many questions and concerns about whether it is safe for mothers with confirmed or suspected COVID-19 to be close to and breastfeed their babies during the pandemic.
To address their questions, WHO has released a list of Frequently asked question...s: Breastfeeding and COVID-19. The FAQ complements the WHO interim guidance: Clinical management of severe acute respiratory infection when COVID-19 is suspected and draws upon other WHO recommendations on infant and young child feeding.
The FAQs aim to provide information to healthcare workers supporting mothers and families in maternity services and community settings, and communicate how the interim guidance should be implemented. Additionally, the FAQs provide information about the protective effects of breastfeeding and skin-to-skin contact, and the harmful effects of inappropriate use of infant formula milk.

Female Genital Schistosomiasis (FGS) is a gynaecological disease caused by Schistosoma haematobium, a parasitic worm that is acquired by skin contact with freshwater contaminated by schistosome cerceriae. Communities in which the infection is most endemic have limited access to clean water and healt...hcare services. Up to 150 million adolescent girls and women are estimated to be at risk of FGS and about 16–56 milion womens are living with FGS, with the majority of these in sub-Saharan Africa. The variability of these estimates points to the fact that this neglected tropical disease is not well studied and frequently not prioritized by local, regional, and global health policy makers.

Nat Commun 9, 5370 (2018). https://doi.org/10.1038/s41467-018-07804-8. Mycobacterium ulcerans is the causative agent of Buruli ulcer, a neglected tropical skin disease that is most commonly found in children from West and Central Africa. Despite the severity of the infection, therapeutic options are... limited to antibiotics with severe side effects. Here, we show that M. ulcerans is susceptible to the anti-tubercular drug Q203 and related compounds targeting the respiratory cytochrome bc1:aa3. While the cytochrome bc1:aa3 is the primary terminal oxidase in Mycobacterium tuberculosis, the presence of an alternate bd-type terminal oxidase limits the bactericidal and sterilizing potency of Q203 against this bacterium. M. ulcerans strains found in Buruli ulcer patients from Africa and Australia lost all alternate terminal electron acceptors and rely exclusively on the cytochrome bc1:aa3 to respire. As a result, Q203 is bactericidal at low dose against M. ulcerans replicating in vitro and in mice, making the drug a promising candidate for Buruli ulcer treatment.

Buruli ulcer caused by Mycobacterium ulcerans is a neglected tropical disease characterized by extensive ulceration involving predominantly the upper and lower limbs of patients. The disease is common in rural tropical communities in West and Central Africa, where access to proper health care is lim...ited. Pathogenesis of the characteristic painless ulcers is linked to the elaboration by M. ulcerans of a lipid toxin called mycolactone that has potent cytopathic, immunosuppressive, and analgesic effects on a host of cells in cutaneous tissues. Mycolactone is known to profoundly inhibit secretion of a plethora of proteins that are essential for wound healing. Even though a combination antibacterial therapy of streptomycin and rifampicin for 8 weeks is effective for treatment, it relies on good and appropriate wound management to prevent secondary bacterial infections and improve healing. Evidence-based interventions for wound care in Buruli ulcer disease are often lacking and have relied on expert advice and recommendations. Surgical interventions are limited to debridement of necrotic tissue and grafting of extensive ulcers, usually after antibiotic therapy. Patients’ rehabilitation is an important component of care to reduce disabilities associated with the disease and proper integration into the community after treatment.

Mpox is an emerging zoonotic disease caused by the mpox virus, a member of the Orthopoxvirus genus closely related to the variola virus that causes smallpox. Mpox was first discovered in 1958 when outbreaks of a pox-like disease occurred in monkeys kept for research. The first human case was recorde...d in 1970 in the Democratic Republic of the Congo (DRC) during a period of intensified effort to eliminate smallpox and since then the infection has been reported in a number of African countries. Mpox can spread in humans through close contact, usually skin-to-skin contact, including sexual contact, with an infected person or animal, as well as with materials contaminated with the virus such as clothing, beddings and towels, and respiratory droplets in prolonged face to face contact. People remain infectious from the onset of symptoms until all the lesions have scabbed and healed. The virus may spread from infected animals through handling infected meat or through bites or scratches. Diagnosis is confirmed by polymerase chain reaction (PCR) testing of material from a lesion for the virus’s DNA. Two separate clades of the mpox virus are currently circulating in Africa: Clade I, which includes subclades Ia and Ib, and Clade II, comprising subclades IIa and IIb. Clade Ia and Clade Ib have been associated with ongoing human-to-human transmission and are presently responsible for outbreaks in the Democratic Republic of the Congo (DRC), while Clade Ib is also contributing to outbreaks in Burundi and other countries.
In 2022‒2023 mpox caused a global outbreak in over 110 countries, most of which had no previous history of the disease, primarily driven by human-to-human transmission of clade II through sexual contact. In just over a year, over 90,000 cases and 150 deaths were reported to the WHO. For the second time since 2022, mpox has been declared a global health emergency as the virus spreads rapidly across the African continent. On 13 Aug 2024, Africa CDC declared the ongoing mpox outbreak a Public Health Emergency of Continental Security (PHECS), marking the first such declaration by the agency since its inception in 2017.7 This declaration empowered the Africa CDC to lead and coordinate responses to the mpox outbreak across affected African countries. On August 14, 2024, the WHO declared the resurgence of mpox a Public Health Emergency of International Concern (PHEIC) emphasizing the need for coordinated international response.
As of August 2024, Mpox has expanded beyond its traditional endemic regions, with new cases reported in countries including Sweden, Thailand, the Philippines, and Pakistan. Sweden has confirmed its first case of Clade 1 variant, which has been rapidly spreading in Africa, particularly in DRC. The emergence of this new variant raises concerns about its potential for higher lethality and transmission rates outside Africa.
