1/8. trichomonas vaginalis in a perinephric abscess. A case report.

    A patient with chronic vulvo-vaginitis due to trichomonas vaginalis, and obstructive uropathy associated with renal calculi, developed a perinephric abscess following trauma incurred in a motorcycle accident. T. vaginalis was seen on smear and cultured from the purulent drainage from the perinephric abscess. Although T. vaginalis is commonly pathogenic only to the lower genito-urinary system, the upper urinary tract may very rarely be involved by ascending infection. If this protozoan spreads to extraluminal sites the inflammatory potential is marked, as has been found in animals with experimental infection. Examination of a fresh smear of pus may be critically important in the diagnosis of closed-space infections of unknown etiology.

2/8. lymph node infection by Trichomonas tenax: report of a case with co-infection by mycobacterium tuberculosis.

    In an 82-year-old woman, presenting with fever and asthenia, cervical adenopathy was noted. Clinical and radiological investigations were fruitless. Laboratory examinations detected a refractory anemia. The lymph node was excised and showed numerous trichomonads on touch preparations. Histologically, the node showed caseous necrosis and macrophagic reaction. diagnosis of lymph node infection by Trichomonas tenax was made. Three weeks later, culture of the node showed mycobacterium tuberculosis and let us conclude co-infection. T tenax is usually regarded as a harmless saprophyte of the oral cavity. This exceptional observation shows for the first time an invasive potential of T tenax. It raises questions about links with tuberculosis and refractory anemia.

3/8. Neonatal pneumonia caused by trichomonas vaginalis.

    The authors present two cases of newborn babies infected by trichomonas vaginalis (hereafter referred to as T. vaginalis) and suffering from severe congenital breathing difficulties and needing artificial respiration. Microscopic examination of the tracheal discharge revealed characteristically moving, flagellated, pear-shaped unicellular organisms. Cultures on CPLM medium proved the presence of T. vaginalis. During pregnancy the mothers' clinical status was negative and both of them mentioned leukorrhoea of changing intensity. They were regularly involved in antenatal care. The infection caused by T. vaginalis could be detected in the two mothers later by culture procedures.

4/8. trichomonas infections in men.

    trichomonas vaginalis, a common pathogen in the female genital tract, produces a characteristic clinical picture in women. Less well recognized are the manifestations of Trichomonas infestations of the male genital tract, which include urethritis and chronic prostatitis. Multiple-glass urinalysis and selective use of Trichomonas cultures may improve recognition of this organism in the family practice setting.

5/8. trichomonas vaginalis infection of the median raphe of the penis.

    A case of trichomonas vaginalis infection involving the median raphe of the penis is presented. The infection was contracted after sexual exposure. The patient had no urethral discharge but had a penile swelling tht discharged pus. Microscopic examination and culture of the discharge showed the presence of T. vaginalis. Treatment with metronidazole (250 mg thrice daly for seven days) eradicated the infection, but the swelling remained and a cyst was excised. One month after the surgical procedure, the patient was clinically normal and cured of the infection.

6/8. colitis associated with metronidazole therapy.

    A 46-year-old woman was treated with oral metronidazole for trichomonal vaginitis and developed diarrhea, which persisted for five weeks. Tissue culture assay of stool supernatant showed a cytopathic toxin that was neutralized by clostridium sordellii antitoxin, and cultures yielded clostridium difficile, which produced a similar or identical cytotoxin in vitro. This isolate proved sensitive to metronidazole at 0.25 microgram/ml. Prior reports have indicated that metronidazole may also be used therapeutically in patients with antibiotic-associated colitis ascribed to other agents. The patient presented here shows the enigma that the same agent used for therapy of colitis may also cause this complication.

7/8. Sexually acquired metronidazole-resistant trichomoniasis in a lesbian couple.

    A lesbian couple in a monogamous relationship each presented with vaginal discharge demonstrable on culture to contain trichomonas vaginalis. Their symptoms had failed to respond to standard regimens of metronidazole, and subsequent microbiological sensitivities confirmed resistance of the trichomonads to metronidazole (minimum inhibitory concentrations in aerobic conditions > 8 mcg/ml). In addition, the couple denied use of penetrative sex toys or recent male partners, supporting the concept of transmission through mutual masturbation.

8/8. Trichomonas tenax empyema in an immunocompromised patient with advanced cancer.

    A 53-year-old male acromegalic patient with advanced rectal adenocarcinoma developed pleuritis in the course of cobalt irradiation, steroid treatment and chemotherapy. Examination of drained pleural fluid demonstrated numerous motile organisms, which were identified as Trichomonas tenax by Giemsa staining. peptostreptococcus micros was also detected in the cultures of pleural fluid and blood. Treatment with metronidazole successfully eliminated the protozoa and cured the pyothorax.
