A 37-year-old man was admitted to hospital with fever, muscle tenderness, headache and mild exanthema on the right thigh. During his hospital stay, the headache worsened and aseptic meningitis was diagnosed. A bilateral iritis developed, and the exanthema developed into an atypical erythema nodosum. In liver function tests, pathological results were recorded. Vasculitis was suspected but could not be confirmed. All serological tests proved negative except for a fourfold titre rise to Chlamydia pneumoniae. We concluded that the meningitis, hepatitis, iritis and atypical erythema nodosum were most probably due to a C. pneumoniae infection.

Sexually transmitted diseases (STD) cause lower genital tract infections (cervicitis, vaginitis) or ascending infections of the fallopian tubes, and, possibly, pelvic inflammatory disease (PID). The syphilis bacterium, human immunodeficiency virus (HIV), and the hepatitis virus cause systematic disease. Although oral contraceptives (OCs) are the most reliable contraceptive method, they have limited anti-STD properties and their relationship with STDs remain unclear. Various mechanisms explain a protective role of OCs against STDs; however, in no way can OCs be considered a safe anti-STD contraceptive method, when compared to specific barrier methods, which provide both contraception and anti-STD protection. The above has been confirmed by a recent study performed in our institution where 10.3% and 6.9% of OC users presented a prevalence of Chlamydia trachomatis and Mycoplasma, respectively, when compared to 0% and 4.5% infection rates found among condom users. It is concluded that although OCs possess some anti-STD properties, mainly in the prevention of PID, they should be used in combination with a barrier method.

Different kinds of infectious agents seem to be implied in the atherosclerotic process. Indeed, some bacteria and viruses have been identified in atherosclerotic lesions: Chlamydia pneumoniae, Helicobacter pylori, Streptococcus sanguis, Porphyromonas gingivalis, herpes simplex viruses type 1 and 2, coxsakievirus B and hepatitis virus A. By their ability to induce antigenic and functional changes in the cells of the vascular wall (endothelial cells, smooth muscle cells, monocytes/macrophages, and fibroblasts) and to stimulate immune response as well as oxidative stress, it is more and more tempting to speculate that infectious agents probably play key roles in the initiation and in the formation of atherosclerotic plaques in certain patients.

The Fitz-Hugh-Curtis syndrome is a peri-hepatitis following a genital infection. It usually occurs in young women. Chlamydia trachomatis is the most frequent causal agent. Clinical signs include acute or recurrent pain in the right hypochondria. Liver tests are not modified and the sonographic examination is normal. Diagnosis can be suspected on the basis of serology, and formally established by laparoscopy showing violin string-like adhesions. Prolonged antibiotic treatment is effective.

A 26-year-old woman presented with a high-grade fever and chills of 2 days' duration. She complained of associated joint pain, especially in the wrists and knees. One day before admission, tender skin lesions began to develop on the fingers, and subsequently spread to the more proximal extremities. The patient recalled having a sore throat and a nonproductive cough before the onset of the fever and eruption. The past medical history was significant for Gardnerella vaginitis and several urinary tract infections. The patient was taking oral contraceptive pills; her most recent menstruation was 3 weeks before admission. She reported having sexual intercourse with her boyfriend 2 weeks before admission. The patient's temperature was 40 degrees C. Dermatologic examination revealed a 6-mm, hemorrhagic pustule on an ill-defined pink base, overlying the volar aspect of the left second proximal interphalangeal joint (Fig. 1a). Scattered on the upper and lower extremities were occasional round, ill-defined pink macules with central pinpoint vesiculation (Fig. 1b). A skin biopsy of the digit revealed a dense neutrophilic infiltrate with leukocytoclasis and marked fibrin deposition in the superficial and deep dermal vessels (Fig. 2a). Gram stains demonstrated the presence of Gram-negative diplococci (Fig. 2b). Laboratory findings included leukocytosis (leukocyte count of 20 x 109/L, with 81% neutrophils). Analysis of an endocervical specimen by polymerase chain reaction was positive for Neisseria gonorrhoeae and negative for Chlamydia trachomatis. Throat and blood cultures grew N. gonorrhoeae. Specimen cultures obtained by skin biopsy yielded no growth. Results of serologic analysis for human immunodeficiency virus, hepatitis, syphilis, and pregnancy were negative. Beginning on admission, intravenous ceftriaxone, 2 g, was administered every 24 h for 6 days, followed by oral cefixime, 400 mg twice daily for 4 days. Oral azithromycin, 1 g, was administered to treat possible coinfection with C. trachomatis. By treatment day 4, the patient was afebrile, with the resolution of leukocytosis and symptomatic improvement of arthralgias.

Fitz-Hugh-Curtis syndrome (FHCS) is a condition with right upper quadrant pain in association with pelvic inflammatory disease. Invasive procedures such as laparoscopy or laparotomy were indispensable to definite diagnosis of FHCS, and no more useful methods in radiological diagnosis of FHCS has been reported until now. In this present study abdominal enhanced-CT findings were analysed retrospectively in eight cases diagnosed clinically as FHCS. We focused on hepatic capsular enhancement, which was identified on early phase in all cases and on delayed phase in five. Moreover, hepatic capsular enhancement was detected at the anterior surface of medial segment and the lateral aspect of right lobe in all cases, while at the anterior surface of lateral segment in five cases. These findings, which disappeared on follow-up CT after treatment, were thought to reflect "acute" peri-hepatitis. Abdominal enhanced CT, especially on early phase, is suggested to be a non-invasive, useful modality for the diagnosis of FHCS. When hepatic capsular enhancement is identified in the interpretation of abdominal enhanced CT images in sexually active women who have right upper abdominal pain, we should suspect the possibility of FHCS and examine gynecological findings or the value of IgA and IgG antibodies for Chlamydia trachomatis.

There is much evidence to suggest the existence of racial differences between blacks and whites in the behaviour of endothelial function. Infective state, sustained by viral or bacterial agents, may injure the endothelial surface favouring the onset and progression of atherosclerotic process, mainly by an inflammatory mechanism. The aim of the study was to investigate endothelial function, expressed as brachial flow-mediated vasodilation (FMV), in black and white healthy subjects, along with antibody titer to cytomegalovirus, hepatitis virus (B, C), herpes virus-1 and 2, Epstein-Barr, Chlamydia pneumoniae and the expression of adhesion molecules. We enrolled 22 young (mean age 27+/-8 years) healthy subjects of black race (10 males) and 20 healthy young subjects (10 males, mean age 28+/-9 years) of white race. Total infectious burden (TIB) was defined as the number of serological positive infections. Black subjects have a reduced brachial FMV (6.9+/-3.5% versus 11.6+/-3.0%, p<0.01) and increased values of hsCRP (0.35+/-0.15 mg/dL versus 0.07+/-0.08 mg/dL, p<0.05), white cells (8578+/-1041/mmc versus 5833+/-998/mmc, p<0.01) and adhesion molecules (respectively: sVCAM-1 945+/-142 versus 779+/-93, sICAM-1 534+/-107 ng/mL versus 325+/-80 ng/mL; both p<0.01) in comparison to white subjects. The total infectious burden in black race was significantly higher than in white race (5+/-1 versus 2+/-1, p<0.01). At the univariate analysis, brachial FMV was significantly related to the levels of adhesion molecules (respectively: sVCAM-1 r=-0.49; sICAM-1 r=-0.50, both p<0.05), hsCRP (r=-0.47, p<0.05) and white blood cells (r=-0.43, p<0.05). TIB was associated with brachial FMV (r=-0.64, p<0.05), sVCAM-1 (r=0.55, p<0.05) and hsCRP (r=0.47, p<0.05). At the multivariate analysis the only predictive variables for brachial FMV were hsCRP, TIB and brachial diameter (respectively: beta=-0.49, -0.19, -0.54, all p<0.05). This study confirms that endothelial reactivity is impaired in young African black patients; moreover its behavior is strictly related to the inflammatory state and to the total infectious burden.

The XXth century is marked by the substantial increase in human life expectancy. Historically, main reasons for that are four achievements of medicine: (1) improvements in common hygiene, such as waste disposal and water purification which led to the significant reduction of communicable diseases; (2) common recognition of Pasteur's Germ Theory followed by improvements in occupational and personal hygiene as well as introduction of antiseptic and aseptic measures; (3) decrease in childhood mortality due to the discovery and widespread application of vaccination; and (4) the discovery and clinical application of antibiotics. An epidemiological transition took place, i.e. the shift from communicable infectious diseases, as a main cause of morbidity and mortality, to chronic degenerative diseases, mainly considered non-infectious. Experimental evidence has been accumulated on a significant number of microorganisms, including viruses (such as a group of herpes viruses, hepatitis viruses, etc.), bacteria (Chlamydia, Helicobacter, periodontal pathogens, etc.), fungi and parasites, as an underlying reason for many of diseases, such as atherosclerosis, various cancers, type 1 and 2 diabetes, neurodegenerative and some psychiatric diseases, osteoporosis, autoimmune diseases and others. On the other hand, most of these diseases have been traditionally associated with age, together with other "age-related" disorders, such as immune system suppression, thymus involution, pathologic calcification, etc. Taken together, these facts suggest that aging, among others, has infectious origins, and that burden of infections may lead to enhanced senescence and premature death. In fact, infections may serve as a trigger of senescence, presumably via the mechanisms of chronic oxidative stress, low-grade inflammation, telomere shortening, and autoimmune processes due to the molecular mimicry. We believe that next step in human longevity increase can be possible by common appreciation of the role of infections as the main trigger of age-related diseases and disorders, and by efforts to cure and/or eradicate these infections.

Atherosclerosis is caused by multiple factors. Infectious disease has been proposed to be one of the causative factors, and several bacteria and viruses have been studied for their correlations with atherosclerotic diseases; these organisms include Chlamydia pneumoniae, Helicobacter pylori, HIV, CMV, HSV and hepatitis viruses. Many underlying mechanisms that infectious diseases cause atherosclerosis have been proposed; most of them suggested that inflammatory process provoked by infectious diseases led to atherosclerosis. Several clinical studies were also performed to examine whether treatment for infectious diseases could protect against atherosclerosis. However, the relationship between infectious diseases and atherosclerotic diseases and the effects of treatment for infectious diseases on atherosclerosis are still controversial; there are both positive and negative reports. Thus, further studies are needed to clarify the correlation.

The adult film industry nowadays represents a legal multi-billion dollar business. The main health risks of adult performers are well known. They mainly include the transmission of sexually transmitted diseases such as HIV, hepatitis, gonorrhoea, Chlamydia, herpes and papillomavirus. However, despite regular follow-up, the frequency of STD remains significant in this high-risk population since a large part of the industry continues to reject systematic use of condoms. Besides, performers are also exposed to other physical and mental health issues often not known to the public. This article provides a comprehensive review of what is known about STD and other risks among the community of performers in the adult film industry.
