Gastric syphilis: polymerase chain reaction detection of treponemal DNA in pseudolymphomatous lesions

Syphilis is an unexpected diagnosis in the stomach. To establish the diagnosis, evidence of Treponema pallidum in the gastric lesion is necessary. However, it is sometimes difficult to prove the presence of the organisms by conventional methods. The authors describe two cases of early gastric syphilis with pseudolymphomatous histology in which T pallidum gene was detected by the polymerase chain reaction (PCR) using paraffin biopsy sections. The gastric lesion of each case endoscopically and histologically simulated that of malignant lymphoma. However, no clonality was proved by immunohistochemistry or PCR gene rearrangement analysis. No spirochetal organisms were detected with certainty by Warthin-Starry silver stain, whereas the organisms were shown by immunofluorescent stain in one patient. A PCR study showed the treponemal DNA in both patients, and its validity was supported by a direct sequencing and a restriction enzyme digestion. Positive results of serological tests for syphilis and regression of the lesions after antisyphilitic treatment were confirmatory of the diagnosis. Gastric syphilis should be considered as a differential diagnosis when an atypical lymphoid infiltrate fails to show monoclonality. The present PCR method would be helpful in showing T pallidum using routinely processed small biopsy specimens as the tissue source.     

Ocular syphilis and neurosyphilis in a patient with human immunodeficiency virus infection

A patient who presented with severely decreased bilateral vision was found to have syphilis and neurosyphilis that responded well to a 14-day course of penicillin and prednisone. The patient tested positive for HIV, which can alter the natural course of syphilis, often making the diagnosis and treatment difficult. Conventional therapy for syphilis may not be effective in patients with HIV. Any patient with syphilis who is in a high-risk group should be tested for HIV; conversely, any patient with HIV should be tested for syphilis if signs or suspicions exist.     

A new look at the serology of treponemal disease

The serology of treponemal disease has become simpler and more rational in recent years, mainly as a result of the widespread adoption of specific antibody tests and the use of monospecific fluorescent antibody procedures which give information about the immunoglobulin class of antibodies. A set of tests which has proved particularly useful in routine diagnosis is the following: quantitative TPHA test, quantitative VDRL test, and monospecific (IgG and IgM) FTA-ABS tests. This combination is especially valuable in the assessment of new patients with positive results to serological tests and in the management of patients with treated syphilis.     

Human immunodeficiency virus seropositivity in adolescents with syphilis

OBJECTIVE: The purpose of this study was to assess the relationship between syphilis and human immunodeficiency virus (HIV) infection among inner-city, minority group adolescents. METHODS: From August 1989 through June 1990, serum from all positive serologic tests for syphilis, obtained from patients attending a comprehensive adolescent health center in an acquired immunodeficiency syndrome epicenter and its two school-based clinics, were frozen without patient identifiers and were subsequently screened for HIV by enzyme-linked immunosorbent assay with confirmatory Western blot for positives. In addition, a retrospective chart review was performed for all patients with a positive serologic test for syphilis during the study period. RESULTS: Of the 59 specimens with a positive syphilis serologic test, 9 (15.3%) were HIV seropositive. Of the patients with syphilis, 57.4% were black and 42.6% were Hispanic; 16.4% were male (mean age 18.1) and 83.6% were female (mean age 17.8). Only 1 subject (female) was an injection drug user; 4 of the male subjects self-identified as having had sex with other males. Of the subjects, 27.8% had primary, 19.7% had secondary, and 52.5% had latent syphilis at the time of diagnosis. A prior or concurrent sexually transmitted disease was present in 90% of the males and 80% of the females; gonorrhea was the most prevalent sexually transmitted disease in the males (89%) and chlamydia was most prevalent in the females (35%). A history of chancroid and/or herpes was present in 16.4% of the subjects. CONCLUSIONS: It is concluded that the diagnosis of syphilis in an adolescent is a risk factor for HIV infection. All sexually active adolescents should be routinely screened for syphilis, regardless of sexual practices. Those with syphilis should be specifically counseled about their increased risk for HIV infection and the importance of consistent condom use, and they should be referred for formal HIV pretest counseling.     

Problems in physician's classification and reporting of congenital syphilis

The diagnosis of congenital syphilis (CS) in newborns can only be made through a review of the mothers' testing and treatment history and through the infants' clinical and laboratory findings. We describe difficulties in the classification of CS by physicians and the health department during a recent syphilis epidemic. The records of infants identified as potential cases of CS by laboratory testing, discharge diagnosis, or health department records were reviewed by epidemiologists. The reasons for concordance and discordance in classification between the physician and the epidemiologist were determined. Congenital syphilis was identified in 126 infants. Seventeen cases were discordant and 12 cases concordant but the physician's classification was for incorrect reasons. Misclassification occurred because physicians lacked data known to the health department (n=7), health departments lacked data known to the physician (n=1), and physicians misinterpreted the case definition for CS (n=21). Suggestions for improving the diagnosis and reporting of CS are included.     

Cerebral gumma showing linear dural enhancement on magnetic resonance imaging--Case report

A 51-year-old male presented with a rare cerebral gumma accompanied by abducens nerve paresis and cerebellar infarction. Magnetic resonance (MR) imaging demonstrated a homogeneous enhance mass lesion and adjacent linearly enhanced dura mater. Histological examination of the mass revealed a caseating granuloma. Serological studies were positive for active syphilis. Although linear dural enhancement adjacent to the mass lesion on MR imaging is characteristic of meningioma, this finding is also demonstrated in cerebral gumma. Therefore, cerebral gummas should also be included in the differential diagnosis. Immunological tests for syphilis (serum, cerebrospinal fluid) can confirm the diagnosis.     

Early syphilis

Given the transmission of Treponema pallidum during human sexual contact, syphilis now occurs in France only in sexually high-risk, disadvantaged populations. The English-language terminology of "early syphilis" has progressively replaced that of "primary" and "secondary" in French usage. Induration of the chancre and the papular nature of secondary skin rashes remain the best criteria for clinical diagnosis. Serological tests associate test specific for treponematoses (Treponema pallidum haemagglutination assay, TPHA) and a nonspecific screening test (Venereal diseases research laboratory, VDRL) to confirm clinically suspected disease. Routine use of long-acting penicillin (benzathine penicillin) is consistently effective. The continuing risk of active syphilis in a pregnant woman and the possibility of severe syphilis in HIV patients require vigilance.     

Long-term trends of the incidence of syphilis and gonorrhoea in the Slovak Republic during 1947-1994, with special regard to young age groups

During the Second World War and after the War venereal diseases (Syphilis and Gonorrhoea) were wide-spread. By a single census in October 1947 were notified 2960 syphilitic patients. In the years 1949-1951 intensive and effective preventive measures were introduced as compulsatory notification system of venereal diseases, sexual contact-tracing investigations, correct and rapid diagnosis of venereal diseases, rapid and efficient therapy of patients with syphilis, followup (post-treatment observations) for all patients, routine serological tests for syphilis, in expectant mothers at ante-natal clinics, periodical screening of high-risk groups, patients in each calendar year at their hospitalization, to taking up a post and a special drive against syphilis ("PN-action"). The results of these measures are manifested by substantial fall in the number of cases of syphilis and gonorrhoea. In the years 1948-1955 18,151 patients suffering from syphilis were notified. The changes of the incidence of syphilis and gonorrhoea are illustrated by statistical data (Tab. 1-9). Syphilis congenita occurs sporadicly, there is a substantial fall in the number of syphilitic pregnant. After 1989 there has been a greater group mobility and a substantial rise in active and passive tourisms and occupational travel activity, especially abroad. Changes of the sexual behaviour were expressed, especially a greater tolerance whether heterosexual or homosexual, sexual freedom, sexual promiscuity and especially prostitution.     

The erythrocyte sedimentation rate in syphilis

The erythrocyte sedimentation rate was studied in 520 men and 202 women with syphilis. It was raised in 66-6 per cent. of sero-negative primary cases, 80 per cent. of sero-positive cases, 100 per cent. of secondary cases, 80 per cent. of early latent cases, and 73-9 per cent. of late latent cases. It was also raised in sixteen out of seventeen cases of neurosyphilis and in all eleven cases of cardiovascular syphilis. It was concluded that the ESR had little place in the management of syphilis in general, but could be helpful in the post-treatment follow-up of late syphilis.     

Maternal and congenital syphilis

Testing for syphilis during pregnancy reveals a positive serologic status in 0.02% of cases. However, a 66% rate of stillbirths is noted in women who are infected and who have not benefited from any treatment. Routine screening is at present performed during the early stages of pregnancy but a second serologic test during the third trimester is useful in the diagnosis of a late infection especially in drug users or HIV (human immunodeficiency virus) positive patients. Congenital syphilis is diagnosed in utero when a positive maternal serologic status is associated with ultrasound images showing fetal abnormalities; these include hepatosplenomegaly, hyperechogenic bowel, signs of bowel obstruction or fetal hydrops. Maternal syphilis is treated by delayed action penicillin and is indicated even for patients allergic to the antibiotic which in this particular case is delivered after desensitization. First line therapy by intravenous penicillin is indicated when confronted with the following high risk factors of congenital syphilis: an elevated titre of VDRL (venereal disease research laboratory) at the time of diagnosis or delivery, unknown date of the precise onset of the infection, the appearance of a rash or of a chancre during pregnancy, ultrasound fetal abnormalities or late therapy during the third trimester. Treatment of the new-born child will depend on the results of clinical, serologic and X-ray evaluation. Long term follow-up for at least a year is mandatory.     

Adhesive interaction between lymphocytes and sinusoidal liver cells

Despite an effective vaccine for rubella and reliable serological methods for detecting syphilis, these pathogens remain important potential causes of congenital infections. This article describes the epidemiological factors that have contributed to the reemergence of these disorders and summarizes the clinical features, microbiological diagnosis, and strategies for treatment or prevention of congenital rubella and congenital syphilis.     

Bone and joint manifestations of systemic infectious diseases

Bone and joint infections can occur as the consequence of a wide variety of systemic diseases. Disseminated fungal and mycobacterial infections, hepatitis, syphilis, gonorrhea, Lyme disease, and AIDS can all have osteoarticular manifestations. A thorough knowledge of the wide range of potential pathogens is key to establishing a correct diagnosis and instituting appropriate treatment.     

Gastric ulcers: a rare manifestation of secondary syphilis

Gastric lesions in the progression of syphilis are very rare and they have several forms of presentation resembling lesions of different nature. We describe a case of secondary syphilis in an heterosexual patient, with persistent gastric ulcers and hepatic affection, in which the evolution and the observations with laparotomy suggested neoplasia. In the gastric biopsy, an infiltration of plasmatic and neutrophil cells was observed and in the hepatic biopsy, necrotic nodules and granulomas. The spirochaeta-specific tinction, although not indispensable, confirms the diagnosis of gastric syphilis. The previous presence of a syphilitic chancre and typical cutaneous lesions are of great help in suspecting a luetic process.     

Plasma levels of clonidine following epidural bolus injection in children

PURPOSE: To describe dense vitritis as the primary manifestation of ocular syphilis in three human immunodeficiency virus (HIV)-positive patients and to determine the response of these patients to the established regimen for neurosyphilis. METHODS: Anti-Toxoplasma gondii IgM and IgG antibody titers, tuberculin skin test, chest radiograph, and serum angiotensin-converting enzyme level were obtained because tuberculosis, sarcoidosis, and toxoplasmosis were in the differential diagnosis. Two of the three patients were not known to have HIV infection at the time of initial examination and consented to HIV testing. Treponemal and nontreponemal tests were performed on serum and cerebrospinal fluid to establish a definitive diagnosis. Treatment for neurosyphilis was initiated, and daily ophthalmic examinations were performed, with careful attention to signs commonly associated with syphilitic eye disease. RESULTS: All three patients exhibited improvement in visual acuity and resolution of vitreous haze. There was no evidence of other signs of posterior uveitis. The one patient for whom there has been a 6-month follow-up showed no sequelae of his eye disease. CONCLUSIONS: Human immunodeficiency virus-positive patients with syphilis may present atypically dense vitritis. In these patients, vitritis may be the first manifestation of syphilis. The regimen for neurosyphilis provides effective therapy. Moreover, in some patients, syphilitic vitritis may be the initial manifestation of HIV disease.     

Syphilis in pregnancy: a medical audit in a rural district

A medical audit was performed in Umzingwane District, Zimbabwe, to assess the quality of antenatal care in 1991 regarding detection and management of syphilis. Two thousand one hundred and sixty one women booked for antenatal care, 1433 (66 pc) received a RPR test result, 197 (14 pc) tests were positive. In 32 (16 pc) of the 197 RPR positive women the outcome of the pregnancy could not be established. Of 165 women 111 (67 pc) received adequate treatment for syphilis. A perinatal mortality rate (PNMR) of 173/1,000 was associated with inadequately or not treated RPR positive mothers and a PNMR of 21/1,000 with RPR negative and untested mothers (odd's ratio = 9.9; 95 pc confidence interval 3.8-24.9, p < 0.001). It is estimated that only 42 pc of all pregnant women and 24 pc of the couples with syphilis in 1991 were treated adequately. Recommendations are made to improve the quality of surveillance of syphilis in pregnancy in a rural district.     

Interesting case no. 15. Double median neck cyst

The aim of this study was to assess which patients are referred from general practice, in order to target areas in which our service could be improved. An anonymous postal questionnaire was sent to 433 local general practitioners (GPs), 72.3% (313) of whom replied. The majority of GPs indicated that they would always send patients with a diagnosis of either gonorrhoea or syphilis to the department, while most would send less than 50% of patients with Chlamydia trachomatis infection. Viral infections (i.e. warts and herpes) were referred more frequently than chlamydia. Referral of trichomoniasis was uncommon, as was advice about contacts in all conditions except gonorrhoea and syphilis.     

100 years of dermatovenereology in Bosnia-Herzegovina

The beginnings of dermatovenerology in Bosnia and Herzegovina are described in the paper in the chronological order. The first written documents, in an official health institution, date from the year 1846, when the Vakuf's Hospital was built in Sarajevo. In the national pathology the treatment of syphilis was priority, fungus diseases, pioderm, skin diseases and leprosy. In 1894 a modern (at that time) Regional Hospital was built up, opened in Sarajevo, 1894 with a Dermatovenerologic Department (60 beds). VIIIth German Dermatovenerology Congress took place in Sarajevo. The main subjects were: leprosy, pelagra, syphilis. In 1897 the first leprosium was built up here being the only one on the Balkans and this part of Europe. The post World War 2, 15 years were characterized by the prevention of syphilis, fungus diseases, pioderm and parasites. The scientific work started, publications came to existence, the authors originating from Bosnia. Later, the dermatovenerology departments in other towns were established (Mostar, Zenica, Biha?, Foca, Travnik, Bugojno), while Banjaluka and Tuzla, established clinics of their medical faculties, which had been opened in the towns. In 1992, the Dermatovenerology Clinic became one of the units of the Clinical Centre in Sarajevo.     

Correlation of cyanogenic glycosides with content of benzyl alcohol in cherry brandies (author''s transl)

The case is described of a patient suffering from gummata of the testes and of the penis, and asymptomatic neurosyphilis. The diagnosis was made on the clinical findings and the strongly positive serological tests for syphilis. It was further supported by the response to penicillin.     

Monitoring effectiveness of controlling hospital acquired infections by prevalence surveys

BACKGROUND: Although congenital syphilis usually occurs as a result of a failure to detect and treat syphilis in pregnant women, failures of the currently recommended regimen to prevent congenital syphilis have been reported. CASE: This report describes an infant with congenital syphilis despite maternal treatment with a regimen exceeding current CDC guidelines. CONCLUSION: Regardless of the regimen used to treat syphilis during pregnancy, clinicians should recognize the possibility of occasional treatment failures and the importance of adequate follow-up of infants at risk for congenital syphilis.
