[Hansen's disease. Case report of tuberculoid leprosy in Chile]. / Enfermedad de Hansen. Comunicación de un caso de lepra tuberculoide en Chile.

Hansen's disease or leprosy is a chronic infectious disease caused by Mycobacterium leprae, mainly affecting the skin and peripheral nerves. In recent years, a better control of the disease has been achieved globally. However, in Chile the incidence of leprosy has continued to increase. We present a case of a 40-year-old patient Haitian nationality with lesions and histopathology compatible with tuberculoid leprosy. We discuss the importance of education on less prevalent diseases in Chile, in conjunction with a review of the pathophysiology, clinic, and classification of Hansen's disease.

Enfermedad de Hansen: comunicación de un caso de lepra tuberculoide en Chile / Hansen's disease: case report of tuberculoid leprosy in Chile

Resumen La enfermedad de Hansen o lepra es una enfermedad infecciosa crónica causada por Mycobacterium leprae, y que afecta principalmente la piel y nervios periféricos. En los últimos años, se ha logrado un mejor control de la enfermedad en forma global. Sin embargo, en Chile la incidencia de la lepra ha ido en aumento. Presentamos el caso clínico de un paciente de 40 años, haitiano, con lesiones e histopatología compatibles con una lepra tuberculoide. Se discute la importancia en la educación sobre enfermedades menos prevalentes en Chile y se hace una revisión sobre la fisiopatología, clínica y clasificación de la enfermedad de Hansen.

Inventory of the epidemiological situation of leprosy in Haiti (2013-2017) for the Five-Year Plan: A first stage toward the implementation of the international strategy to combat leprosy, 2016-2020.

Leprosy is endemic in Haiti and remains a disease misunderstood by the population. In 2018, the national program to fight tuberculosis and leprosy (PNLTL) produced its first strategic plan against leprosy to implement the international strategy of the World Health Organization (WHO). The objective of this study was to describe the epidemiological situation of leprosy in Haiti, to assess its prevalence and morbidity, and to guide the strategies of the national plan. A retrospective study of all cases of leprosy diagnosed in the three centers providing care for this disease in Haiti reviewed the new cases at these centers from January 2013 through December 2017. In all, 232 new patients were recorded, or 49 new cases a year. Multibacillary leprosy was predominant: 86%, compared with the international mean of 60 %. Children accounted for 14 % of the new cases (7.5 % internationally), a finding that is evidence of active community transmission. Of the new cases in 2017, 8 %, including one child, had grade 2 impairments. Nearly all the leprosy cases - 94 % (218/232) - came from the two districts with treatment centers (West and Artibonite). Efforts must continue to implement the international strategy to fight leprosy to ensure a reduction by 2020 in the rate of grade 2 impairments among new cases and the number of new cases among children.

[Update of knowledge on Neglected Diseases in Haiti: Mansonelliasis, Tungiasis, Leprosy, and Anthrax]. / Mise à jour des connaissances concernant quatre maladies délaissées en Haïti : mansonellose, tungose, lèpre, charbon.

Haiti, like most limited-resources countries in the world, faces numerous neglected infectious diseases. They represent a real public health issue with lethal consequences especially in children. We are reviewing here the available literature on four neglected infectious diseases, mansonelliasis, tungiasis, leprosy and anthrax. Filariasis, due to Mansonella ozzardi, has been totally neglected since its discovery in 1920 in Haiti; it persists in coastal homes with a high prevalence in adults when an effective treatment is available. The skin lesions caused by Tunga penetrans have existed since the pre-Columbian period in Haiti. They persist in the most retreated and hard-to-reach areas where the population lives in precarious conditions and in extreme poverty. New available research data show the importance of the problem with very high prevalence rates in some rural communities far away from any healthcare center. Cases of leprosy are recently reemerging as no monitoring program has been in place since 2004. Finally, anthrax is still endemic; small epidemics resurfacing periodically in families in rural areas. Screening of people for these diseases and managing the cases are necessary to improve health and reduce morbidity and mortality in Haiti.

Comme dans la plupart des pays pauvres de la planète, les maladies infectieuses négligées sont nombreuses en Haïti où elles représentent un réel problème de santé publique avec des conséquences létales, surtout pour les enfants. Nous faisons le point des données accessibles pour quatre d'entre elles. Totalement délaissée depuis la découverte de sa présence en Haïti en 1920, la filariose due à Mansonella ozzardi persiste en foyers côtiers avec une prévalence élevée chez les adultes alors qu'un traitement efficace est disponible. Connues depuis la période précolombienne dans l'île d'Hispaniola, les lésions cutanées dues à Tunga penetrans persistent dans les régions les plus reculées et difficiles d'accès où la population vit dans des conditions précaires et dans une très grande pauvreté. Nous rapportons les données d'enquêtes récentes qui montrent l'importance de cette ectoparasitose en Haïti où les taux de prévalence sont très élevés dans certaines communautés rurales isolées. Des cas de lèpre resurgissent en Haïti alors qu'aucun programme de surveillance n'est effectif depuis 2004. Enfin, la maladie du charbon est endémique dans les régions d'élevage où des épidémies familiales resurgissent périodiquement en milieu rural. Le dépistage des personnes atteintes de ces maladies et leur prise en charge sont nécessaires pour une amélioration de la santé et une baisse de la mortalité en Haïti.

Type 1 leprosy reversal reaction treated with topical tacrolimus along with systemic corticosteroids.

An 11-year-old black Haitian boy presented with borderline lepromatous leprosy and was treated with rifampicin, dapsone, and clofazimine. After 4 months he developed a severe type 1 reversal reaction without nerve involvement. He was started on prednisolone (1 mg/kg daily). After 4 weeks of treatment with corticosteroids, his condition did not improve and the lesions remained painful. The patient was given a therapeutic trial with twice daily application of topical tacrolimus 0.1% ointment. The result was a dramatic improvement in the skin lesions. The patient's condition was maintained by topical tacrolimus therapy, with healing of all skin lesions. The prednisolone dose was then tapered to zero over a period of 12 weeks. To the best of our knowledge, this is the first report of the efficacy of topical tacrolimus in the treatment of type 1 leprosy reaction.

[Leprosy in Haiti]. / Aspects de la lèpre á Haïti.

Leprosy has yet a great impact on public health in Haiti. A study was carried out in Haiti from 1977 to 1999. On 2,160 registered cases, mostly are paucibacillaries: 412 cases are under 15 year old patients and 1,306 more than 15 year old. Multibacillaries cases are 85 in under 15 year old patients and 357 in more than 15 year old. By the improvement of sanitary conditions, detecting cases and multidrug therapy, leprosy had decreased during these last years, with an incidence from 0.1 to 0.2%. However, with the increasing poverty and political disorders, the control of leprosy remains difficult in Haiti.

Yellow fever, malaria and development: Atlantic Africa and the New World, 1647 to 1928

Malaria and yellow fever in the Atlantic world (Africa, the Caribbean, mainland America) are treated. In the evolution of these diseases, Development (involving the involuntary migration of millions of potential laborers from East to West) is found to be a principal motor force. As with leprosy in the nineteenth century, disease Constructs were important on shaping dominant peoples` attitutes. Construct yellow fever held that black Africans were immune to the disease. This mischievous understanding was taken to demonstrate that the Christian God had specially created them to serve as slaves in North, Meso- and South America. In Africa and Liverpool in the 1890s, British medical personnel further marginalized blacks by creating a malaria Construct.(AU)

Human T cell lymphotropic virus (HTLV-1): cutaneous manifestations

Skin manifestations are a common feature of HTLV-1 associated disorders and of HTLV-1 infection itself. These include the lymphomatous skin infiltrates in adult T-cell lymphoma/leukaemia, most commonly manifesting as persistent, generalised papules, nodules and plaques with later ulceration, acquired ichthyosis and xeroderma in HAM/TSP, infective dermatitis of children, dermatomyositis, crusted (Norwegian) scabies, psoriasiform rashes which may precede one of the more serious disease associations, and possibly also seborrhoeic dermatitis. Disorders typically associated with immunosuppression such as disseminated herpes zoster, and ulcerative non-healing herpes simplex may also be seen occasionally both in ATK as well as in other wise asymptomatic HTLV-1 infection (AU)
