Syphilis, a chronic, sexually transmitted disease caused by the extracellular spirochete Treponema pallidum, has exhibited a remarkable resurgence in recent years. Despite the existence of inexpensive, easily administered, and highly effective antibiotic treatments, maternal and neonatal syphilis infections continue to be a major global public health problem. In addition to its potential to cause morbidity in the mother, untreated gestational syphilis (GS) can lead to serious adverse outcomes in the offspring, including stillbirth, prematurity, low birth weight, and neonatal death. Congenital syphilis (CS) is regarded as a missed opportunity during the antenatal care of the mother, resulting from socioeconomic, demographic, and behavioral factors that promote mother-to-child transmission (MTCT) of syphilis. This chapter emphasizes emerging concepts about screening aimed at controlling the ongoing epidemic, including serological screening of mother and infant, newer paradigms of “reverse screening,” clinical presentation, therapy, and long-term neurodevelopmental disabilities that must be a component of follow-up care.

Abstract Background and Aims Chronic kidney disease (CKD) and chronic obstructive pulmonary disease (COPD) represent a global public health problem worldwide. As such, both conditions are associated with high disease-related morbidity and mortality. However, it is unclear whether the presence of CKD aggravates the clinical course of COPD and vice versa. Method In a novel murine model of cigarette smoke (CS)-induced lung injury combined with an adenine nephropathy model, kidney and lung inflammation, and fibrosis were studied. Moreover, in 2,314 patients with stable COPD enrolled in the prospective, multi-centre COSYCONET study, urinary Dickkopf-3 (DKK3), a biomarker of kidney injury and CKD progression was quantified. The association between urinary DKK3 and trajectories of forced expiratory pressure in 1 second (FEV1) and estimated glomerular filtration rate (eGFR) during a median follow-up of 37.1 months, exercise capacity, risk of exacerbation, and mortality was determined. Results In the CKD-COPD animal model, the presence of kidney injury was associated with increased systemic and pulmonary inflammation, impaired pulmonary function, as well as more severe damage of the lung architecture. Moreover, CS enhanced kidney fibrosis. Accordingly, in the COPD patients from the COSYCONET study, higher urinary DKK3 was associated with declining FEV1 during follow-up (OR 3.36, 95% CI 2.22-5.08). Moreover, high urinary DKK3 was associated with higher risk for exacerbation (OR 1.24, 95% CI 1.03-1.50), lower 6-minute walking distance, and higher all-cause mortality (HR 1.49, 95% CI 1.08-2.05). Importantly, high urinary DKK3 was associated with declining eGFR during follow-up (OR 2.23, 95% CI 1.22-4.07) independently from baseline kidney function and proteinuria, which was confirmed by a machine learning approach. Conclusion These data uncover a novel pathophysiological link between CKD and COPD. Patient with COPD and concomitant CKD are at high risk for worsening pulmonary function and adverse outcomes. Elevated urinary DKK3 allows identification of COPD patients with progressive CKD. Measurement of urinary DKK3 in patients with COPD may therefore represent a novel tool for risk stratification and the identification of patients, who might in particular benefit from preventive therapeutic strategies to prevent progression of COPD and CKD as well.

Introduction: This study aimed to document the prevalence of syphilis among pregnant women in Turkey. Methodology: In this retrospective cohort study, a total of 63,276 sera obtained between January 2007 and June 2014 from women who were routinely screened for syphilis as a part of antenatal care at a tertiary referral hospital in Turkey were analyzed. Serological screening was done with the rapid plasma reagin (RPR) test on venous blood samples. Treponema pallidum hemagglutination assay (TPHA) was the confirmation test for the diagnosis of syphilis in patients who had positive results in the screening test. Results: Between 2007 and the first six months of 2014, 41 RPR+ and only five confirmed syphilis-positive patients were determined. The syphilis seroprevalence rate was 0.0648%. Within these years, there was no case of congenital syphilis detected in the hospital. Conclusion: As there is evidence of effective screening of syphilis contributing to the effective treatment and prevention of adverse outcomes, routine antenatal screening of syphilis is recommended. The rationale depends on the consideration of the serious results of not treating the disease and the cost effectiveness of screening.

ABSTRACTInvestigation ofTreponema pallidumsubsp.pallidum, the spirochete that causes syphilis, has been hindered by an inability to culture the organism continuouslyin vitrodespite more than a century of effort. In this study, long-term logarithmic multiplication ofT. pallidumwas attained through subculture every 6 to 7 days and periodic feeding using a modified medium (T. pallidumculture medium 2 [TpCM-2]) with a previously described microaerobic, rabbit epithelial cell coincubation system. Currently, cultures have maintained continuous growth for over 6 months with full retention of viability as measured by motility and rabbit infectivity. This system has been applied successfully to the well-studied Nichols strain ofT. pallidum, as well as to two recent syphilis isolates, UW231B and UW249B. Light microscopy and cryo-electron microscopy showed thatin vitro-culturedT. pallidumretains wild-type morphology. Further refinement of this long-term subculture system is expected to facilitate study of the physiological, genetic, pathological, immunologic, and antimicrobial susceptibility properties ofT. pallidumsubsp.pallidumand closely related pathogenicTreponemaspecies and subspecies.IMPORTANCESyphilis, a sexually transmitted disease with a global distribution, is caused by a spiral-shaped bacterium calledTreponema pallidumsubspeciespallidum. Previously,T. pallidumwas one of the few major bacterial pathogens that had not been cultured long-termin vitro(in a test tube), greatly hindering efforts to better understand this organism and the disease that it causes. In this article, we report the successful long-term cultivation ofT. pallidumin a tissue culture system, a finding that is likely to enhance our ability to obtain new information applicable to the diagnosis, treatment, and prevention of syphilis.

Abstract Background Hidradenoma papilliferum is a rare benign neoplasm arising from apocrine glands. It occurs commonly on the anogenital region of middle-aged women. It usually presents as a slow growing, solitary asymptomatic, skin colored or red nodule less than 1 cm in diameter. Case presentation The case is a 38-year-old, white woman who presented with a painful nodule occurring within a month in the himenal region of the posterior vaginal introitus. The nodule was excisied and the histology revealed a hidradenoma papilliferum. The diagnosis and treatment of hidradenoma papilliferum is possible with surgical removal and histopathological evaluation of nodules. Conclusion When an adult woman presents with a noduler lesion in the anogenital area, sexually transmitted diseases and other benign and malignant vulvar lesions, as well as malignant transformation is very rare but,should be kept in mind; however because it has been reported and long-term clinical follow-up is suggested

Abnormal liver function tests (LFTs) are known to be associated with impaired clinical outcomes in heart failure (HF) patients. However, this implication varies with each single LFT panel. We aim to evaluate the long-term outcomes of acute HF (AHF) patients by assessing multiple LFT panels in combination. From a prospective multicenter registry in Japan, 1158 AHF patients who were successfully discharged were analyzed (mean age, 73.9 ± 13.5 years; men, 58%). LFTs (i.e., total bilirubin, aspartate aminotransferase or alanine aminotransferase, and alkaline phosphatase) at discharge were assessed; borderline and abnormal LFTs were defined as 1 and ≥2 parameter values above the normal range, respectively. The primary endpoint was composite of all-cause death or HF readmission. At the time of discharge, 28.7% and 8.6% of patients showed borderline and abnormal LFTs, respectively. There were 196 (16.9%) deaths and 298 (25.7%) HF readmissions during a median 12.4-month follow-up period. The abnormal LFTs group had a significantly higher risk of experiencing the composite outcome (adjusted hazard ratio: 1.51, 95% confidence interval: 1.08–2.12, p = 0.017), whereas the borderline LFTs group was not associated with higher risk of adverse events when referenced to the normal LFTs group. Among AHF patients, the combined elevation of ≥2 LFT panels at discharge was associated with long-term adverse outcomes.

Tuberculosis is a global public health problem and is among the top ten causes of mortality in the world. We present the unusual case of a 37-year-old woman, referred for fever, progressive headache, nausea, vomiting and change in mental status. Brain imaging studies. showed a left frontal brain abscess with subfalcin herniation. As an urgent procedure, surgical drainage of the brain abscess was performed, and in the culture of pus there was growth of an anaerobic Streptococcus. The histopathological study of the abscess wall showed data on tuberculosis. The patient was pregnant at surgery, for about five weeks and received anti-tuberculous medications with close maternal fetal follow-up. Pregnancy came to term and was resolved by an elective cesarean section, both mother and child had a favorable evolution.

Abstract Introduction. Syphilis is an infectious disease caused by Treponema pallidum spirochete and is mainly transmitted by sexual contact. Syphilis has the potential to cause serious complications and is closely related to human immunodeficiency virus (HIV) infection thus making syphilis still a major public health problem. In Indonesia, surveys of high-risk populations in 2007 and 2011 reported an increase in the prevalence of syphilis, especially in men who have sexual relationships with other men (MSM). Moreover, studies have described risk factors for HIV transmission including MSM, heterosexual contacts, Intravenous (IV) drug use, and infected partners. Objectives. To assess the epidemiological aspects and risk factors for syphilis in Makassar, as well as the correlation with a coinfection of other sexually transmitted infections. Material and Methods. This study is a multi-centre cross-sectional descriptive study with consecutive sampling. We evaluated cases for eligibility by confirming the diagnosis based on the serological result using rapid plasma reagin assay (RPR), Treponema pallidum haemagglutination (TPHA), and HIV screening kit. The cases were analyzed based on epidemiological features, risk factors and clinical findings, co-infection with other sexually transmitted infection (ST), and stadium of the disease. Results. A total of 79 serologically confirmed syphilis cases were collected between January 2017 and December 2018 in Makassar, the capital city of South Sulawesi province in Indonesia. Of the 63 male subjects (79.7%), 38 (48.1%) were homosexual/MSM, and in 41 cases of HIV-infected subjects, 25 (60.9%) of them were also MSM. Conclusion. Our study showed there was a significant correlation between syphilis and an increased risk of HIV transmission in MSM groups. The higher number of cases of syphilis and HIV co-infection among MSM can increase transmission of both infections and should be considered a major risk factor for syphilis in Makassar.

Abstract Syphilis is a bacterial sexually transmitted disease (STD), whose main route of infection is through sexual contact. In order to diagnose syphilis, Treponema pallidum must be detected in the material sampled from a lesion and a blood test must be performed in order to detect serological response to syphilis. Since 1946, a statutory obligation to report all cases of syphilis has been in force in Poland, which is why data concerning the incidence is available. The aim of this paper is to analyse trends in syphilis incidence in the years 1950–2017 using Joinpoint Regression and to present the impact of prophylaxis and education of society on syphilis prevention. The Joinpoint Regression method indicated the splitting time points of the trend corresponding to real changes in incidence, which corroborates the purpose of using the method in question in epidemiological studies.

Background: Guidelines recommend assessing orthostatic hypotension (OH) 3 minutes after rising from supine to standing positions. Hypothesis: Measurements performed immediately after standing will be as informative as measurements performed closer to 3 minutes after standing with regards to symptoms of dizziness or risk of adverse outcomes. Methods: OH, defined as a drop in blood pressure (systolic ≥20 mm Hg or diastolic ≥10 mm Hg) from the supine to standing position, was measured up to five times at 25 seconds intervals in middle-aged (range 44 to 66 years) ARIC participants (1987-1989). Associations between each measurement and history of dizziness upon standing were examined via logistic regression. We used Cox models to examine the association between each of five measurements with risk of fall, fracture, syncope, and all-cause mortality over a median follow-up of 23 years. Results: In 11,449 participants (mean age 54 years, 54% women, 26% black) 10% reported a history of dizziness upon standing. OH assessed at measurement 1 (performed at a mean of 28 seconds after standing) was associated with risk of fall ( P = 0.03), fracture ( P = 0.05), syncope ( P <0.001), and mortality ( P < 0.001) ( Table ). Furthermore, measurement 1 was the only measurement associated with higher odds of dizziness upon standing (OR: 1.5; P = 0.001). Measurement 2 (performed on average 53 seconds after standing) was associated with all long-term outcomes. Measurements 4 and 5 (mean 100 and 116 seconds after standing) were generally less informative with regards to prospective outcomes than earlier measurements and were not statistically associated with history of dizziness. Conclusions: OH measurements obtained, on average, within the first 30 seconds of standing were predictive of long-term adverse health outcomes and were the most strongly related to symptoms of dizziness compared to later measurements. These findings suggest that BP measurements for determining orthostatic hypotension should be performed immediately after standing.

Food insecurity is a significant public health problem in the United States leading to substantial social, economic, and health care–related burdens. While studies continue to estimate the prevalence of food insecurity, the long-term outcomes are not extensively explored. The purpose of this study was to assess the impact of food insecurity on mortality. We analyzed data on adults (≥ 20 years) from the 1999–2010 National Health and Nutrition Examination Survey, with mortality data obtained through 2015. Among the total study participants (n = 25,247), 17.6% reported food insecurity. Food-insecure individuals were more likely to be younger in age, minorities, poorer, with lesser education, obese, smokers, and with diabetes compared to food-secure counterparts. During a 10.2-year follow-up, among the food insecure, 821 individuals died (11%). The hazard ratio (HR) for mortality among the food insecure compared with the food secure, with adjustment for age and gender only, was 1.58; 95% confidence interval [CI: 1.25, 2.01]. The adjusted HRs for all-cause mortality, HR = 1.46, CI [1.23, 1.72], p < .001, and cardiovascular mortality, HR = 1.75, CI [1.19, 2.57], p < .01, were statistically significantly higher among food-insecure individuals, after adjustment for multiple demographic and health risk factors. Individuals who are food-insecure have a significantly higher probability of death from any cause or cardiovascular disease in long-term follow-up. Comprehensive and interdisciplinary approaches to reducing food insecurity–related disparities and health risks should be implemented. Including food insecurity in health risk assessments and addressing food insecurity as a determinant of long-term outcomes may contribute to lower premature death rates.
