[New diagnostic and therapeutic directions in so-called essential anorectal pain].

The authors report a study of 40 patients affected with "essential" ano-rectal neuralgia. It manifests itself by frequent urinary disorders discovered most of the time at the interview of the patient and emphasizes in many cases the presence of psychosomatic disorders. This study has also demonstrated frequent abnormalities of laboratory tests including: chlamydiae serology, urethral samplings and cyto-bacteriological examination of urine looking for: chlamydiae, ureaplasma urealyticum, mycoplasma hominis and common urinary infections. Results of the treatment seemed completely favorable but should be confirmed by a long-term analysis.

[Male genital lesions caused by papillomaviruses. Importance of colposcopy].

Ten years after the description of cervical flat condyloma, it is now admitted that Human Papillomaviruses (HPVs) type 6 and 11 are responsible for condylomata acuminata and typical flat condyloma of the uterine cervix. HPV DNA type 16 and, less frequently, 18, 33 and other as yet uncharacterized HPV types (G. Orth, personal communication), are found in the majority of Cervical Intraepithelial Neoplasia (CIN), Vulvar Intraepithelial Neoplasia (VIN) and cervical and vulvar invasive cancers. Since HPVs are sexually transmissible, recent interest has focused on the "male factor". Clinically detectable lesions of male genitalia are condylomata acuminata, bowenoid papulosis and flat condyloma-like papules. The aim of our study was the colposcopical screening, recently suggested, of different groups of male patients in order to detect HPV-related lesions and the description of the colposcopical features of subclinical HPV-related lesions, since most of them have never been reported, to our knowledge, in the literature. A total of 114 men were examined. Among them, 18 presented clinically detected recalcitrant condylomata acuminata, 28 had been treated for the same pathology 1 to 5 days earlier and were clinically free of lesions, 46 were sexual partners of women with cervical atypia (flat condyloma and/or CIN) and 22 had a clinical diagnosis of genital infection without HPV-related lesions. A careful examination of external genitalia was performed. Then all patients underwent penile colposcopy before and after application of 5 p. 100 acetic acid. Selected biopsies were performed in all lesions which were clinically and colposcopically different from classic warts. Colpophotographs were taken in all cases.(ABSTRACT TRUNCATED AT 250 WORDS)

The prevalence of Chlamydia trachomatis in women with genitourinary symptoms.

Two studies were conducted to determine the prevalence of Chlamydia trachomatis in the urine and cervical exudates of women with genitourinary symptoms. In the first study, 873 women attending the World Health Organization-Sexually Transmitted Disease Center of the Alfred Fournier Institute, in Paris, were examined. In 7% of these women, culture results were positive for the presence of C trachomatis. Women with C trachomatis in the urethra had more polymorphonuclear cells in the urine than did those with C trachomatis in the cervix (P less than 0.001). The second study at the same center involved 180 women with vaginal or urethral signs and symptoms. Positive cultures for C trachomatis were found in 12% of the 140 women reporting vaginal problems and in 22% of the 40 women reporting urinary symptoms. Cell cultures from both the cervix and urethra were positive for C trachomatis in 1.4% of the women with vaginal signs and symptoms and in 2.5% of the women with urinary symptoms. These data support the value of urethral cultures for detecting C trachomatis in women with genitourinary symptoms.

[Contribution of recent methods to the diagnosis of Chlamydia infections].

Chlamydia trachomatis is the most common cause of non- and/or post-gonococcal urethritis in men. The infection is often silent in women, but may be complicated by salpingitis followed by tubal sterility. The direct diagnosis: Since the availability of monoclonal antibodies, the microscopic examination of a smear of the sample is once again a current technique. By using an immuno-fluorescent technique, it is possible to demonstrate the elementary corpuscules in the form of free extracellular particles. This methods is rapid and easy to perform. Culture: Nevertheless, culture remains the reference technique despite the fact that it only reveals "inclusions": clumps of reticulated particles. The technique is simplified by using microculture in flat bottomed microtitration plates, which enables a large number of isolations to be performed in one step. The visualisation by means of monoclonal antibodies is in perfect agreement with classical staining techniques. The serological diagnosis: Micro-immuno-fluorescence (MIF) is still the reference technique. ELISA occasionally fails to correlate with MIF. These discordances can be explained by the different antigens used: protein extracts bound to a support, in the case of ELISA, and whole live particles, in the case of MIF.

[Current methods in the diagnosis of Chlamydia infections].

The pathogenicity of Chlamydia species is no longer questioned and most figures indicate that these organisms are the leading cause of sexually transmitted diseases. Diagnosis by direct examination of a stained slide is not acceptable due to inadequate sensitivity. The use of monoclonal antibodies conjugated to ITCF, however, is a good method to detect chlamydial particles. Cultures are made from specimens of heavily infected cells, centrifuged with cells from the McCoy cell line treated with cycloheximide. The inclusions are visualized using immunological techniques (immunofluorescence or staining with a peroxidase-antiperoxidase reaction). By using wells of microplates, this method is less expensive and can also be used for antimicrobial susceptibility testing. Serology (by MIF or ELISA) is very helpful, especially to investigate complications originating from a lower genital tract infection. Both techniques are useful in routine screening.

[Chlamydia and sexually transmitted germs. Description and bacteriological diagnosis].

In this article, the author emphasizes the articular complications of genital infections caused by gonococci, mycoplasma and Chlamydia. He describes the laboratory techniques used to isolate, identify on appropriate media and, if need be, assay the serum or joint antibodies for each of these micro-organisms. If it is difficult to determine the aetiology of a particular case of joint pain, one should keep in mind the possibility that an old or recent genital infection may be responsible.

Chlamydia trachomatis associated with chronic inflammation in abdominal specimens from women selected for tuboplasty.

Chronic inflammation is a frequent cause of tuboplasty failure. Therefore, it would be useful for one to know the microbiologic agent of infection and to treat it before the tuboplasty. By laparoscopy, a search for Chlamydia trachomatis, Ureaplasma urealyticum, and other microbiologic agents was carried out in the peritoneum and tubes of 118 women divided into 3 groups. Sixty-nine had a checkup before tuboplasty, of which 30 were found to have a chronic inflammatory condition discovered during laparoscopy (group 1) and 39 to have no sign of inflammation (group 2). Forty-nine women with a completely normal pelvis, being followed for possible sterility, were used as a control group. Cultures and serodiagnosis show a significant difference for C. trachomatis between the pathologic groups and the control group. They show no noticeable difference for U. urealyticum. These findings, compared with those by other authors, indicate that C. trachomatis could be an important microbiologic agent in tubal sterility, strongly connected with a low-grade chronic inflammatory condition, and their presence at the time of tuboplasty is to be considered.

Microbiology of specimens obtained by laparoscopy from controls and from patients with pelvic inflammatory disease or infertility with tubal obstruction: Chlamydia trachomatis and Ureaplasma urealyticum.

We cultured for Chlamydia trachomatis, Ureaplasma urealyticum, and Mycoplasma hominis and performed chlamydial serologic studies in 99 women undergoing laparoscopy. These women included patients with acute salpingitis, infertile women with and without mild pelvic inflammatory disease, and controls. C. trachomatis infection was significantly more common in patients than in controls. We also identified low-grade "silent" PID among women with infertility resulting from tubal obstruction and suggest this may be caused by chlamydiae.

[A microbiological study of swabs taken laparoscopically in cases of salpingitis and tubal sterility. Research for Chlamydia trachomatis and for mycoplasmas (author's transl)].

Research was made for chlamydia trachomatis and ureaplasma urealyticum in the peritoneum and the tubes of 99 women divided into 4 groups: 17 of them were being investigated because of acute salpingitis (Group A), 17 were being investigated for tubal sterility with chronic inflammation diagnosed laparoscopically (Group B), 29 were being investigated for tubal sterility without any laparoscopic evidence of inflammation (Group C) and 36 women had absolutely normal pelves and were being investigated for sterility. These were the control group (D). Swabs were also taken from the lower genital tracts as well as serological tests for chlamydia trachomatis and cytological samplings of the fluid from the Pouch of Douglas and the histology of the tubes. In the 17 women who had acute salpingitis the swabs 4 cases of C.T. and 4 of U.U. In the 46 women who had tubal sterility the laparoscopic swabs showed cases of C.T. and 7 of U.U. The swabs were most often positive in Group B. This group is characterised by a special appearence of the inflammation, with fluid present and viscous adhesions as well as peritoneal inflammatory cysts. These altogether help to make a presumptive diagnosis of C.T. infection on laparoscopy. In the control group of 36 cases there was no sign of C.T. in any case, although 2 swabs from the peritoneum showed U.U. So there is a statistically significant difference between the groups that were suspicious and the control group whether the results were obtained by cultures or by serological diagnosis. On the other hand there is no definitive difference as far as U.U. is concerned. These observations, which are similar to those published by other authors, lead us to think that micro-organisms and especially chlamydia trachomatis could be the bacteriological agent responsible for chronic inflammatory states found so frequently in women with tubal sterility.

Secnidazole. A 5-nitroimidazole derivative with a long half-life.

The therapeutic activity of a single 2 g dose of secnidazole was studied in patients with urogenital trichomoniasis. In 140 patients, 97% were cured and the drug was well tolerated. In the laboratory, tests on sensitivity were made and the minimal inhibitory concentration (MIC) and the minimal trichomonacidal concentration (MTC) were determined on cultures that had recently been isolated at the clinic, and the pharmacokinetic properties of secnidazole in man were compared with those of tinidazole. The therapeutic efficacy of all the metronidazole derivatives was reviewed and a single-dose treatment is recommended. Therapeutic and prophylactic treatment is achieved by products with a long half-life. Secnidazole, with a half-life of 14.3 +/- 1.3 h (women) and 20.2 +/- 3.1 h (men), is particularly suitable for this type of treatment.

[New "chlamydia" isolation methods applied to the current medical practice and epidemiology (author's transl)].

From 935 men attending a consultation for veneral diseases and 117 women suffering from vaginal discharge, 1 052 genito urinary tract specimens were inoculated on monolayers of McCoy cells which were irradiated or treated with either cytochalasin B or 5-iodo-2-deoxyuridine. The value of these technics was estimated in routine diagnostic procedures according to the number of positive cultures, regardless of the number of inclusions per culture and also by comparison of the number of inclusions seen in cells inoculated with reference strains of lymphogranuloma venereum, trachoma and human urethral Chlamydia. The best method seems to consist of the use of McCoy cells treated with cytochalasin B for routine isolation and of acridine orange for the staining of inclusions.

[Irradiated cell cultures applied to group A "chlamydiae" isolation (author's transl)].

The irradiated Mc Coy cell cultures method modified by Darougar et al. has been used to investigate the frequency of Chlamydiae in non-specific genital tract disease, in Reiter's disease and in patients suffering from conjonctivits associated with non-specific urethritis. Isolates were obtained from 104 men of the 660 suffering from acute urethritis, and from 18 men of the 67 suffering from conjonctivitis associated with urethritis. Fourteen female sexual contacts of these men were tested: Chlamydiae was isolated from 9. Seven patients suffering from acute Reiter's disease were tested: Chlamydiae was isolated from 4. These patients were tested by complement fixation and titers of 1/8 or more were only obtained in the 4 isolated positive cases, the three other cases remaining negative. Isolates of Chlamydiae were obtained from 10 women of the 67 women suffering from exocervicitis. No isolate was obtained, from 27 control patients.
