This report deals with the geographical distribution, prevalence, epidemiology, etiology, serological, clinical, and histopathological features, and treatment of mal del pinto, or pinta, in Mexico.Repository penicillin preparations (PAM and Panbiotic) have been found highly effective in the treatment of this endemic, non-venereal treponematosis. (+info)ON THE ORIGIN OF THE HUMAN TREPONEMATOSES (PINTA, YAWS, ENDEMIC SYPHILIS AND VENEREAL SYPHILIS). (2/5)
A close relationship between the four human treponematoses is suggested by their clinical and epidemiological characteristics and by such limited knowledge of the treponemes as there is at present. No treponeme of this group (except for that of the rabbit) is known other than in man, but the human treponemes probably arose long ago from an animal infection. The long period of infectiousness of pinta suggests that it may have been the earliest human treponematosis. It may have been spread throughout the world by about 15 000 B.C., being subsequently isolated in the Americas when the Bering Strait was flooded. About 10 000 B.C. in the Afro-Asian land mass environmental conditions might have favoured treponeme mutants leading to yaws; from these, about 7000 B.C., endemic syphilis perhaps developed, to give rise to venereal syphilis about 3000 B.C. in south-west Asia as big cities developed there. Towards the end of the fifteenth century A.D. a further mutation may have resulted in a more severe venereal syphilis in Europe which, with European exploration and geographical expansion, was subsequently carried throughout the then treponemally uncommitted world. These suggestions find some tentative support in climatic changes which might have influenced the selection of those treponemes which still survive in humid or arid climates. Venereal transmission would presumably remove the treponeme from the direct influence of climate. The author makes a plea for further investigation of many aspects of this subject while this is still possible. (+info)On the origin of the treponematoses: a phylogenetic approach. (3/5)

Between 1983 and 1987, 62 out of 76519 pregnancies in 51 mothers had a positive miniaturised Treponema pallidum haemagglutination assay (TPHA) test--1 in 1234, or 0.81 per 1000 births. About two thirds of these mothers had syphilis and the remainder non-venereal treponematoses such as yaws or pinta. Antenatal screening identified 13 patients with previously unknown acquired syphilis, 11 of whom were given antibiotics during pregnancy. There were six fetal losses among the 62 TPHA positive pregnancies, but none had evidence of congenital syphilis. No live born child in this study group showed stigmata of congenital syphilis. It is concluded that despite the current low incidence of syphilis in the United Kingdom it is imperative to continue antenatal serological screening and to emphasise the importance of early adequate treatment of the infection. (+info)Pinta is a mild form of cutaneous leishmaniasis, a tropical infection caused by the Leishmania parasite. It is transmitted to humans through the bite of an infected sandfly.
The disease primarily affects the skin and mucous membranes, causing lesions that can vary in size and appearance. In the case of pinta, these lesions are typically characterized by their red, blue or brown discoloration.
Pinta is endemic in certain parts of Central and South America, but it's relatively rare compared to other forms of leishmaniasis. Early diagnosis and treatment can prevent complications and the development of severe, disfiguring lesions.
Yaws is a chronic, infectious disease caused by the spirochete bacterium Treponema pallidum pertenue. It primarily affects the skin, bones, and cartilage. The initial symptom is a small, hard bump (called a papule or mother yaw) that develops into an ulcer with a raised, red border and a yellow-crusted center. This lesion can be painful and pruritic (itchy). Yaws is usually contracted through direct contact with an infected person's lesion, typically during childhood. The disease is common in rural areas of tropical regions with poor sanitation and limited access to healthcare, particularly in West and Central Africa, the Pacific Islands, and parts of South America and Asia.
Yaws is treatable with antibiotics, such as penicillin, which can kill the bacteria and halt the progression of the disease. In most cases, a single injection of long-acting penicillin is sufficient to cure the infection. However, it's essential to identify and treat yaws early to prevent severe complications, including disfigurement and disability.
It's important to note that yaws should not be confused with other treponemal diseases, such as syphilis (caused by Treponema pallidum subspecies pallidum) or pinta (caused by Treponema carateum). While these conditions share some similarities in their clinical presentation and transmission, they are distinct diseases with different geographic distributions and treatment approaches.
In the context of medical terminology, "history" refers to the detailed narrative of the patient's symptoms, illnesses, treatments, and other related information gathered during a medical consultation or examination. This is usually obtained by asking the patient a series of questions about their past medical conditions, current health status, family medical history, lifestyle habits, and any medications they are taking. The information collected in the medical history helps healthcare professionals to diagnose, treat, and manage the patient's health concerns more effectively. It is also an essential part of continuity of care, as it provides valuable insights into the patient's health over time.
Treponemal infections are a group of diseases caused by the spirochete bacterium Treponema pallidum. This includes syphilis, yaws, bejel, and pinta. These infections can affect various organ systems in the body and can have serious consequences if left untreated.
1. Syphilis: A sexually transmitted infection that can also be passed from mother to fetus during pregnancy or childbirth. It is characterized by sores (chancres) on the genitals, anus, or mouth, followed by a rash and flu-like symptoms. If left untreated, it can lead to serious complications such as damage to the heart, brain, and nervous system.
2. Yaws: A tropical infection that is spread through direct contact with infected skin lesions. It primarily affects children in rural areas of Africa, Asia, and South America. The initial symptom is a painless bump on the skin that eventually ulcerates and heals, leaving a scar. If left untreated, it can lead to disfigurement and destruction of bone and cartilage.
3. Bejel: Also known as endemic syphilis, this infection is spread through direct contact with infected saliva or mucous membranes. It primarily affects children in dry and arid regions of Africa, the Middle East, and Asia. The initial symptom is a painless sore on the mouth or skin, followed by a rash and other symptoms similar to syphilis.
4. Pinta: A tropical infection that is spread through direct contact with infected skin lesions. It primarily affects people in rural areas of Central and South America. The initial symptom is a red or brown spot on the skin, which eventually turns into a scaly rash. If left untreated, it can lead to disfigurement and destruction of pigmentation in the skin.
Treponemal infections can be diagnosed through blood tests that detect antibodies against Treponema pallidum. Treatment typically involves antibiotics such as penicillin, which can cure the infection if caught early enough. However, untreated treponemal infections can lead to serious health complications and even death.
