Between 1905 and 1910, Schaudinn and Hoffman known T basal ganglion because the explanation for sexually transmitted disease, and Wasserman delineate a diagnostic assay for the long-recognized infection. infective treponemes area unit related to the subsequent four diseases:
- Venereal Cupid's itch, caused by T basal ganglion basal ganglion
- Yaws, caused by T basal ganglion pertenue
- Endemic Cupid's itch (bejel), caused by T basal ganglion endemicum (Go to Endemic Cupid's itch for additional complete info on this subject.)
- Pinta, caused by T carateum
The treponemes to blame for these diseases can not be distinguished serologically, morphologically, or by ordination analysis, and that they haven't been with success cultivated on artificial media.
Children expertise two styles of Cupid's itch: nonheritable syphilis, that is sort of solely transmitted by sexual contact, and noninheritable Cupid's itch, which ends up from placental transmission of spirochetes (see Etiology).
Syphilis-especially in its later stages-can have various and complicated manifestations and will fit variety of alternative diseases. Syphilitic manifestations square measure classified as primary, secondary, and tertiary (see Clinical Presentation).
Serologic testing has the first role within the diagnosing (see Workup).
Penicillin remains the drug of option to treat all stages of Cupid's itch (see Treatment and Management, also as Medications).

Pathophysiology
When left untreated, social disease could be a womb-to-tomb infection that progresses in three clear characteristic stages. once initial invasion through secretion membranes or skin, the organism apace multiplies and wide disseminates. The organism spreads through the perivascular lymphatics so the circulation before clinical development of the first lesion. the first lesion, that contains infectious treponemes, arises among hours once infection and persists throughout primary and secondary illness.
Secondary lesions develop once spirochetal invasion of tissues of germ layer origin (eg, skin, secretion membranes, CNS) precipitates AN inflammatory response. These lesions develop 6-12 weeks once infection. This stage of speedy eubacteria multiplication and dissemination might bring invasion of the complete body. Thus, syphilis might involve any organ system.
Secondary infection becomes latent among 1-2 months once onset. Relapses with secondary manifestations will be seen throughout the primary year of latency, a amount remarked because the early latent amount. Early latent social disease (ie, length < one y) is once the repeated lesions of syph area unit presumably to occur. No relapses occur once the primary year; what follows is late social disease, which can be either symptomless (ie, late latent) or symptomatic (ie, tertiary). Late latent social disease is related to resistance to each reinfection and relapse.
Tertiary syphilis will manifest in numerous ways that. membrane social disease seldom happens and presents a couple of years once the initial infection. Late pox might gift as focal anemia of the CNS or stroke as a results of inflammation of little blood vessels of the brain. Meningovascular social disease will have an effect on any a part of the CNS. Actual destruction of the nerve cells within the cortex results in a mix of medicine manifestations and medicine findings.
Congenital social disease is caused by placental transmission of spirochetes; the transmission rate approaches ninetieth if the mother has untreated primary or syph. foetal infection will develop at any time throughout gestation. Manifestations area unit outlined as early if they seem within the initial two years of life and late if they develop once age two years. in line with a Centers for illness management and bar report, untreated social disease, particularly early social disease, throughout physiological state will cause hearing disorder, medicine impairment, bone deformities, stillbirth, and death.
Because inflammatory changes don't occur within the foetus till once the primary trimester of physiological state, organogenesis is unaffected. however, all organ systems is also concerned. With early-onset illness, manifestations result from placental spirochetemia and area unit analogous to the secondary stage of noninheritable social disease. inherent social disease doesn't have a primary stage. Late-onset illness is seen in patients older than two years and isn't thought-about contagious.

Etiology
Syphilis is caused by spirochete basal ganglion, that belongs to the family Spirochaetaceae family. Cupid's itch transmission typically happens transplacentally or by sexual contact. alternative modes of transmission embrace contact with contaminated blood or infected tissues.
Children expertise two sorts of Cupid's itch: noninheritable syphilis, that is nearly solely transmitted by sexual contact, and inherent Cupid's itch, which ends up from placental transmission of spirochetes. Vertical transmission of early Cupid's itch throughout maternity ends up in a inherent infection in a minimum of 50-80% of exposed neonates.

History
Most recognized syphilitic malady in kids is nonheritable. Medical professionals ought to assume that kids with nonheritable Cupid's disease are infected through sex offense, unless another mechanism of transmission is known.
Syphilis-especially in its later stages-can have varied and complicated manifestations and should fit variety of different diseases. Indeed, William Osler known as Cupid's disease "the nice Imitator."

Primary Cupid's disease
The primary lesion, known as a sore, is painless. it always develops at the location of the immunisation, at a mean of three weeks once exposure to T basal ganglion. Patients could ignore a lucid lesion as a result of it's painless unless it becomes secondarily infected. If the sore happens on the female genital organ or within the mouth, it's usually unnoticed by the patient and partner.
Secondary Cupid's itch
Because of the widespread dissemination of spirochetes, frequent constitutional symptoms embrace the following:
Because of the widespread dissemination of spirochetes, frequent constitutional symptoms embrace the following:
- Fever
- Malaise
- inflammatory disease
- Rash
- Anorexia
- Arthralgias
- Generalized painless pathology
Renal, hepatic, and ophthalmologic manifestations could also be gift.
Symptomatic antiseptic infectious disease happens in 1-2% of patients and is characterised by headache, stiff neck, nausea, and regurgitation.
Tertiary social disease
Tertiary syphilis presents with symptoms of infectious disease or with focal deficits per stroke. The mnemotechnical device "PARESIS" is associate aid to recall the subsequent symptoms and signs:
Tertiary syphilis presents with symptoms of infectious disease or with focal deficits per stroke. The mnemotechnical device "PARESIS" is associate aid to recall the subsequent symptoms and signs:
- P ersonality
- A ffect
- R eflexes (eg, hyperactive)
- E ye (eg, Argyll guard pupils)
- S ensorium (eg, illusions, delusions, hallucinations)
- I ntellect (eg, decreased recent memory, orientation, judgment, insight)
- S peech abnormalities
Syphilis at any stage will have an effect on ears and eyes. Such involvement is also the sole presentation, and, therefore, any patient with unexplained hearing disorder, proprioception abnormalities, or ocular inflammation ought to be tested for treponemal antibodies. social disease ought to be thought of within the medical diagnosis of inflammatory ocular high blood pressure syndrome. Patients might gift with inflammation and medical science proof of social disease.
Syphilis in HIV-exposed infants
Several studies have incontestible atypical options of congenial Cupid's disease in infants at the same time infected with HIV and spirochete. These options embody fever, cough, blister or nonblister rash, and sores round the corners of the mouth. One ought to have a high index of suspicion with any such findings in a very newborn that can't be explained by anybody entity.

Physical Examination
Primary sexually transmitted disease
Primary syphilis is characterised by a nontender hickey at the positioning of immunization that quickly erodes, exploit associate lesion (the chancre). the bottom of the lesion is swish, while not exudate, and therefore the borders square measure raised and firm. Painless bodily process enlargement of native humour nodes accompanies the sore and might persist for months.
Primary chancres ad libitum heal at intervals 3-6 weeks.
Secondary sexually transmitted disease
Mucocutaneous lesions square measure the foremost frequent signs of syph and powerfully counsel the identification. Discrete, macular, pink-to-red lesions square measure 3-10 millimeter in diameter and will unfold to involve the complete body, as well as the palms, soles, and alternative locations.
Unlike the first lesions, secondary lesions don't ulcerate. These lesions typically evolve from macules into red papules and, in a very few patients, finally make pustules. sac lesions square measure prominently absent.
Painless generalized pathology is found in eighty fifth of patients.
Broad grey plaques known as condyloma lata is also found in heat, moist, intertriginous areas. (See the pictures below.)
Abnormal bodily fluid (CSF) examination results occur in half-hour of patients with syph, however the patient is also well.
