Randomized comparative study of 0.5 and 1 g of cefodizime (HR 221) versus 1 g of cefotaxime for acute uncomplicated urogenital gonorrhea.

Uncomplicated urogenital and concomitant oropharyngeal gonorrhea in 424 male and female patients was treated in a randomized comparative study with 0.5 g of cefodizime (89 men and 54 women), 1 g of cefodizime (87 men and 52 women), or 1 g of cefotaxime (86 men and 56 women). The cure rates were 100% for men and women in the group given 0.5 g of cefodizime, 100% for men and women in the group given 1 g of cefodizime, and 99% for men and 100% for women in the group given 1 g of cefotaxime. The MICs of cefodizime and cefotaxime for the isolate of Neisseria gonorrhoeae ranged from 0.004 to 0.06 micrograms/ml. Chlamydia trachomatis was isolated before treatment in 15% and after treatment in 13% of all patients. Side effects, such as nausea, diarrhea, abdominal pain, genital candidiasis, and pain at the site of injection, developed in 4% of the patients given cefodizime. Side effects, such as vertigo, genital candidiasis, fatigability, and diarrhea, developed in 4% of the patients treated with cefotaxime. In both groups of patients, the side effects were mild and transient. Cefodizime and cefotaxime are safe and effective agents in the treatment of uncomplicated urogenital gonorrhea.

Congenital syphilis in The Netherlands: cause and parental characteristics.

During 1982-5 the 19S (IgM) fluorescent treponemal antibody absorption (19S (IgM) FTA-ABS) test gave positive results in 19 children. The parental histories were analysed. As five of the children were adopted, 14 pregnancies were evaluated. Mothers of foreign origin and extramarital pregnancies were found to be over-represented. Of 13 women who attended for pregnancy checkup, three were not serologically screened for syphilis. In four the infection had developed late in the course of pregnancy. In at least four treatment had not been given or had been inadequate or too late. At least two had positive 19S (IgM) FTA-ABS test results that did not indicate congenital syphilis. The possibility of false positive 19S (IgM) FTA-ABS test results is pointed out. As the male sexual partners of four of the 14 mothers had presented elsewhere with early syphilis at the time of their partner's pregnancy, adequate contact tracing appears to be important to prevent congenital syphilis in future.

Quinolones in the treatment of gonorrhoea and Chlamydia trachomatis infections.

The results of two therapeutic trials in female patients with uncomplicated urogenital gonorrhoea (A) and in male patients with uncomplicated urethral gonorrhoea (B) treated with either 200 mg and 400 mg enoxacin orally, of one therapeutic trial in male patients with uncomplicated urogenital gonorrhoea treated with either 250 mg or 500 mg ciprofloxacin orally (C) and of one therapeutic trial in male patients with non-gonococcal urethritis (NGU) treated with ciprofloxacin 1 g daily during seven days (D) are presented and compared with the results of other investigators. The cure rate in study A was 100% (n = 40) in the 400 mg group and 95.7% (n = 46) in the 200 mg group. The cure rate in study B was 92% (n = 78) in the 400 mg group and 90% (n = 77) in the 200 mg group. In both studies no antichlamydial effect of enoxacin was observed. The cure rates in study C were 100% with 250 and 500 mg. An antichlamydial effect seemed to be present. In studies A, B and C side effects were minor and rare and were mainly nausea and headache. In study D (100 patients suffering from NGU) disappearance of Chlamydia trachomatis and Ureaplasma urealyticum one day after the end of treatment was observed in 29 of 32 (91%) and 28 of 32 (88%) cases, respectively. Pyuria disappeared in 44% and 74% of the patients showed clinical cure. However, two weeks after the end of treatment Chlamydia trachomatis and Ureaplasma urealyticum were observed in respectively six and eight cases. In 30% pyuria was still absent. Side effects were only minor.(ABSTRACT TRUNCATED AT 250 WORDS)

Evaluation of an enzyme immunoassay for detection of herpes simplex virus antigen in genital lesions.

To evaluate a non-marketed research prototype of a solid-phase enzyme immunoassay for detection of herpes simplex virus in genital lesions, 154 clinical specimens were collected from 127 men and 27 women with symptoms suggestive of herpes simplex virus infection (erythema, vesicles, ulcers and crustae). The samples were tested using the assay and cultures on four monolayers of human embryonic lung fibroblasts and Vero cells. When the culture was used as reference method, sensitivity was 76.9% and specificity 100% (prevalence 42.4%). Comparison of results by patient group showed that sensitivity was highest in material from patients with vesicles and ulcers. The highest sensitivity was obtained in specimens which developed a cytopathological effect within 48 h and in specimens with three or four positive cell cultures. These findings suggest that the assay is more successful in specimens with high virus titres. The enzyme immunoassay was found to be a rapid, moderately sensitive, highly specific test for detection of herpes simplex virus from genital lesions, but the usefulness of the assay is limited and culture methods should be preferred.

Enzyme-linked immunofiltration assay for rapid serodiagnosis of syphilis.

A new rapid technique for detection of serum treponemal antibodies is described which is based on an enzyme-linked immunoassay using nitrocellulose as solid phase. With this technique antigen-antibody binding is accelerated by the filtration of the antibody solution through the antigen-coated nitrocellulose filter instead of its remaining over the solid phase for incubation. Test results are available in less than 15 min. Serum specimens from 255 syphilitics and 829 non-infected subjects were investigated. The sensitivity and specificity of the Treponema pallidum enzyme-linked immunofiltration assay were comparable to those of the Treponema pallidum haemagglutination assay and the fluorescent treponemal antibody absorption test.

Treatment of clue cell-positive discharge with 200 mg povidone-iodine pessaries. A double-blind and placebo-controlled trial.

In a double-blind randomized study we evaluated the efficacy of povidone-iodine in the treatment of clue cell-positive discharge (CCPD). Vaginal pessaries (200 mg povidone-iodine or placebo) were taken twice daily for five consecutive days. Although the regimen was reasonably well accepted, 'messiness' was reported by 13 of 33 women (39%). Of 44 women enrolled, treatment efficacy was evaluated in 28 women who had both follow-up visits. There was no significant difference in the efficacy of povidone-iodine and placebo pessaries, at either the first or the second follow-up visit (p values 0.46 and 1 respectively). It is concluded that the use of povidone-iodine pessaries, at least in the regimen described, cannot be regarded as an effective therapy for CCPD.

Amoxycillin, amoxycillin-clavulanic acid and metronidazole in the treatment of clue cell-positive discharge. A comparative clinical and laboratory study.

In an open study, 30 women with clue cell-positive discharge (CCPD) were treated for seven days with either amoxycillin, amoxycillin-clavulanic acid or metronidazole (ten in each group). Patients were monitored on days 2, 4, 9 and 15. Clinical and microscopical parameters were used to assess treatment efficacy. Gas-liquid chromatography of vaginal secretions was also performed. The succinate-lactate ratio had good correlation with the clinical findings. All patients treated with metronidazole were cured by day 4, suggesting that a three-day course is as effective as the standard seven-day regimen. Treatment with amoxycillin-clavulanic acid was less effective resulting in the cure of seven patients by day 15. Amoxycillin established normal secretions in only four patients. Gastro-intestinal complaints, although common in patients treated with amoxycillin-clavulanic acid, were generally mild. We consider amoxycillin-clavulanic acid a possible alternative in the treatment of CCPD.

Replication characteristics and core size of intranuclear herpes simplex virus (HSV-1) in genital skin lesions: electronmicroscopy studies of a biopsy from a female patient.

Herpes simplex virus (HSV) type 1 genital infection, leading to ulcerating lesions in a female patient, was studied by electronmicroscopy. Infection had probably been recent, through oro-genital contact with a cold sore on the husband's lip. Cell-culture typing and serological tests indicated that the patient currently had an HSV-1 secondary infection. Aspects studied in a skin biopsy from an ulcerating labium majus were epidermal cell types infected, stages in virus genesis, virus core diameter in intranuclear capsids and extracellular appearance of virus. Different stages in virus genesis, in virus envelope formation and in nuclear and cytoplasmic degeneration were observed in the few remaining, rounded and swollen, epidermal (?) spinosum cells. Their nuclei, some with marginated chromatin, harboured besides dense-cored or empty capsids, electron-dense blobs possibly representing clones of immature virus and falling apart into aggregates of small granules. In other nuclei, large clusters of dense-cored capsids, some distinctly hexagonal in shape, had accumulated in wide gaps in the nuclear membrane whereas remaining nuclear membrane portions were quadruple and often engaged in viral envelope formation. Partially enveloped capsids and naked dense-cored capsids were seen extracellularly indicating their survival outside cells. An occasional virion was present in dermal blood vessel lumina. Measurements of the electron-dense core (nucleoid) of intranuclear capsids in electronmicrographs showed that the HSV-1 core diameter differs very significantly from the core of intranuclear HSV-2 capsids, thus allowing a clear distinction by electronmicroscopy between the two HSV subtypes in plastic-embedded biopsies.

Localized unilateral hyperhidrosis.

A case of unilateral hyperhidrosis of the face is described. Measurements of the rate of evaporative water loss from other areas of the body, showed a marked left-right difference in the sweating rate on the arms and on the legs which had not been suspected clinically. Unilateral hyperhidrosis is a rare and puzzling disorder. Possible neurological causes are discussed.
