TRICHOMONAL VAGINITIS—The Problem of Chronic or Recurring Infection

In general practice and in gynecology, vaginal trichomoniasis is a frequent and troublesome problem. However, the trichomonas vaginalis organism is frequently found in an apparently healthy vagina, indicating that symptoms, recurrences, or exacerbations may depend on local changes in secretions, probably due in part to emotional stress. Therapy must, therefore, include not only the topical use of an effective trichomonacidal drug, but also sympathetic and considerate listening by the physician.The combination of furazolidone and nifuroxime in vaginal suppositories and vaginal insufflation powder was found to be an effective trichomonacidal compound. A total of 56 patients with trichomonal, monilial and nonspecific bacterial vaginitis was treated with this nitrofuran combination with good results.In topical therapy, powders seem more effective, probably because a dry environment is unfavorable to the flagellates. The patient should be instructed to insert two vaginal suppositories daily for the first week, then to decrease the dosage gradually as indicated by the physician after clinical examination and microscopic examination of vaginal secretions each week. Of great importance is the fact that some patients may need long-term maintenance therapy—one or two suppositories weekly—especially if the emotional difficulties appear to be insurmountable.     

Vaginally administered 16, 16-dimethyl-prostaglandin E2 as an agent for pre-operative cervical dilatation.

Twenty-one women in the 10th-12th week of pregnancy were treated prior to vacuum aspiration with vaginal suppositories containing 16, 16-dimethyl-PGE2 (free acid). An average total dose of 3.4 mg led to abortion or adequate cervical dilatation in all patients. Based upon previous experience with the compound, no prophylactic anti-emetic or anti-diarrhetic medication was given. Gastrointestinal side effects were minimal. Excessive bleeding was not observed. In two cases, slight temperature elevation was noted prior to abortion. The low incidence of side effects in combination with the effectiveness of the compound help to make this method an attractive therapeutic adjunct to vacuum aspiration beyond the 10th week of gestation. Under the experimental conditions of this study, the results suggest that vaginally administered 16, 16-dimethyl-PGE2 can be a safe and effective method for cervical dilatation before vacuum aspiration.

Eficacia del econazol en embarazadas con candidiasis vulvo-vaginal

Among the female patients attending the out patient clinic of the Obstetric Service of the University Hospital of Caracas, Venezuela a hundred were chosen who presented vaginal discharge and itching. The presence of C. albicans and the existence of candidiasis in the vulvo-vagina of the 100 pregnant women was investigated. Those patients where candidiasis was found, were also investigated as to the simultaneous presence of C. albicans in the mouth and the anal skin. Gyno-Pevaryl therapy was performed by administering one 150 mg ovule daily for three consecutive days. At the same time, their partners were treated with Pevaryl 1% cream. The post-therapy control was made 36 hours after conclusion of treatment and further check-up were made one week and two weeks later. Only those patients who attended the post-treatment controls were taken into account for the evaluation of the results. C. albicans was identified in 60 cases by nascent culture of the vulvar secretions, using a bile-agar medium. Of these, 50 had vulvo-vaginal candidiasis (hyphae and blastospores on direct examination). 92% of the women with vulvo-vaginal candidiasis complained about pruritus at the moment of the examination. No significant differences were observed with respect to the age, the period of gestation and parity of the positive and negative patients. Of the 40 patients who attended only the first control, 23 were cured (57.5%), 9 improved (22.5%) and 8 (20%) were not cured. The cure rate increased to 70% and 72.5% taking into account those patients, who also attended the second and the third consecutive treatment sessions, respectively. In those patients suffering from vulvo-vaginal candidiasis, 37.5% were found to be carriers of C. albicans in the mouth and 70% also in the anal region. This seems to indicate that the mouth and the anal region can constitute the source of re-infection in the majority of the cases following topical vaginal treatment.

Controlled trial of induction of labor by vaginal suppositories containing prostaglandin E2.

A group of 84 women at 39-43 weeks of pregnancy were randomly allocated to a blind trial of induction of labor with vaginal suppositories containing inert material or either 0.2 mg or 0.4 mg of prostaglandin E2. The suppositories were self-administered every two hours during waking hours on two successive days until labor started or 15 had been used. Side-effects were absent. Labor was established within 48 hr of insertion of the first suppository in 9.3% of control patients, 65.4% of those treated with 0.2 mg PGE2 and 85.7% of those treated with 0.4 mg PGE2. The mean Apgar scores in the three groups were the same. The mean total dose of PGE2 were 2.0 mg (0.2 mg group) and 2.3 mg (0.4 mg group). It is concluded that vaginal PGE2 is an effective and acceptable method of inducing labor at term.

Midtrimester abortion induced by serial intravaginal administration of prostaglandin E2 suppositories in conjunction with a contraceptive diaphragm.

Midtrimester abortion was successfully induced in 68 of 69 patients with serial intravaginal administration of prostaglandin E2 suppositories behind a contraceptive diaphragm. The mean abortion time for the successful inductions was 13.07 hours; multiparous patients aborted somewhat faster, mean 12.72 hours, as compared to nulliparous patients, mean 14.22 hours. In 36 patients the PGE2 suppositories were placed behind an intact diaphragm and the mean abortion time was 14.89 hours. In 33 patients the PGE2 suppositories were placed behind a diaphragm modified by having an opening incised in the center, the mean time in these patients was 11.96 hours. Of the 68 successful abortions 59% of the patients aborted in 12 hours or less and 88% aborted within 24 hours. The most frequently encountered side effect was temperature elevation of 2 degrees F or higher which occurred in 68% of the patients. Temperatures returned to normal levels within 4 to 6 hours after the last adminstration of PGE2. Gastrointestinal side effects occurred in 45% of patients, but these side effects were well tolerated and did not require termination of drug administration in any of the patients. Intravaginal administration of PGE2 suppositories is a very effective abortifacient technque during the midtrimester, however the use of PGE2 in conjunction with a diaphragm did not appreciabley improve the technique although the amount of drug administered and the incidence of side effects was somewhat lower than when the PGE2 suppositories are used alone. If a diaphragm is to be used, a modified diaphragm is indicated since it simplifies the clinical management of the abortion, eases administration of the suppositories and permits a more accurate estimation of cervical changes, vaginal bleeding and abortion.     

Factors of the local immune defence of the reproductive tract in pregnant women with vaginosis

Clinico-immunological examination of 99 pregnant women with diagnosed vaginosis and 132 pregnant women without genital infection as a control group, was carried out. The immunological factors of cervical and vaginal secretions in pregnant women before and after local treatment were studied. The conclusion was made that the established changes in the cell-mediated and humoral factors of the immune resistance of the reproductive system could probably play some pathogenetic role in the development of vaginosis and its relapses in pregnant women. As found in this study, more pronounced changes in the local factors of immune protection (the signs of the functional irritation of neutrophils in combination with the prevalence of sIgA and lysozyme simultaneously with a decrease in the level of IgM and IgG in cervical slime) developed in patients with subsequent relapses of vaginosis, these changes remaining after local treatment. The defects of cell-mediated and humoral factors of cervical and humoral secretions, together with some clinical parameters, were shown to be prognostically unfavorable with respect to the relapses of vaginosis in pregnant women.

Maturation of social reward in adult male Syrian hamsters does not depend on organizational effects of pubertal testosterone

The rewarding value of female sexual stimuli develops across puberty, as sexually-naïve adult, but not prepubertal, male hamsters show a conditioned place preference (CPP) for both vaginal secretions and a receptive female. Similarly, only adults show an endogenous testosterone surge when they encounter vaginal secretions. Testosterone by itself can condition a place preference in male rodents. Therefore, Experiment 1 assessed whether the endogenous testosterone surge elicited by vaginal secretions is necessary to show a CPP. Both gonad-intact and gonadectomized, testosterone-treated adult males showed a CPP for vaginal secretions, indicating that the rewarding value of this social cue is independent of an endogenous testosterone surge. However, organizational effects of pubertal testosterone could be necessary for adolescent development of social reward, as pubertal testosterone organizes adult-typical expression of sexual behavior. To investigate this possibility, in Experiment 2, sexually-naïve prepubertal and adult male hamsters were gonadectomized and received testosterone-filled capsules four weeks later. Testing began after two weeks of testosterone replacement. Adult males showed a CPP for both vaginal secretions and a receptive female, whether or not they experienced pubertal testosterone. Thus, the acquisition of positive valence of sexual stimuli is not organized by pubertal testosterone. Taken together, the ability of female sexual stimuli to serve as an unconditioned reward to adult male hamsters is independent of the chemosensory-induced endogenous testosterone surge and also organizational effects of pubertal testosterone. Instead, sexual reward may be dependent either on activational effects of testosterone or gonadal hormone-independent mechanisms.     

Anti-trichomonal IgA antibodies in trichomoniasis before and after treatment

Anti-trichomonal IgA antibodies were estimated by enzyme-linked immunosorbent assay (ELISA) in serum and vaginal secretions of 25 symptomatic and 25 asymptomaticTrichomonas vaginalis positive patients before and after treatment and in 25 age-matched controls. Significantly higher levels of antitrichomonad IgA antibodies were found inT. vaginalis positive patients when compared to control subjects, especially in vaginal secretions. In addition, a significant decrease in these antibodies was observed after treatment, which was more pronounced in vaginal secretions. It seems that anti-trichomonal IgA antibodies in serum and more so in vaginal secretions are directly related to and specific to the presence ofT. vaginalis in the urogenital tract.     

Biomarkers of leukocyte traffic and activation in the vaginal mucosa

Development of novel vaginal spermicides and anti-human immunodeficiency virus (HIV) microbicides requires careful assessment of their potential to recruit and activate CD4+ HIV-1 host cells in the female genital tract mucosa, two events that facilitate HIV-1 infection. Leukocyte traffic and activation are mediated by proinflammatory cytokines and chemokines, e.g. interleukin (IL)-1, IL-6 and IL-8, which have been detected in vaginal secretions in association with epithelial damage and infections. These proinflammatory mediators, however, have bidirectional, destructive as well as beneficial, effects on the mucosal barrier, and may be counterbalanced by endogenous inhibitors. Here we propose additional biomarkers for the evaluation of compound-induced cervicovaginal mucosal inflammation. Displaying different temporal patterns of detection, the levels of soluble E-selectin, vascular adhesion molecule-1, CD14 and myeloperoxidase in vaginal secretions reflected the mucosal leukocyte reaction to proinflammatory compounds being evaluated for safety in an improved rabbit vaginal irritation model. These biomarkers, which were also detected in human vaginal secretions, may be used to enhance the characterization of mucosal safety of vaginally applied compounds, both in animal as well as clinical studies.

Gonorrhea—The Office Management of Acute Infections

Gonorrhea has recently increased to epidemic proportions and is poorly controlled. The principal causes are probably increasing resistance of Neisseria gonorrheae to penicillin, the difficulty of establishing the diagnosis and proving the cure in female patients and the inadequacy of resources devoted to the eradication of the disease by public health agencies.While examination of smears is adequate for diagnosis of the disease in males, in females cultures of vaginal exudate are necessary. Gonorrhea can usually be successfully treated with large doses of short-acting penicillins. Intramuscular administration of aqueous procaine penicillin will bring about cure in most cases. Female patients should have cultures for several weeks to make sure they are cured.The physician should report all cases to the local health department so that contacts can be traced and treated.

Medical Assistance to the Aged

Aerosol therapy has three principal objectives: Mobilization of bronchial secretions, relief of bronchospasm and topical chemotherapy. It has become an important tool in the treatment of bronchopulmonary diseases. The equipment for inhalation therapy, however, should be adequate. Both large-capacity and small-capacity nebulizers must be available, and they must be the kind that will produce a mist with most of its particles only 0.5 to 2.5 micra in diameter. These nebulizers may be used alone or in conjunction with a variety of appliances that will deliver the aerosols to the respiratory tract. The use of humidifying agents as aerosols is extremely helpful in patients with retained bronchopulmonary secretions. In some patients who have particularly thick or gelatinous secretions and in patients with mucoviscidosis, ordinary water or saline solution is often not enough. Hypertonic saline may be of value in these cases, and it is suggested that half-molar (2.9 per cent) saline be administered in 10 per cent propylene glycol. In these cases, preparations containing detergents (tyloxypal) or other preparations containing enzymes (desoxyribonuclease or trypsin) may be given by the aerosol technique, with care not to cause irritation.The bronchodilator aerosol agents are of proved benefit in the treatment of bronchospastic disorders and are indicated in most cases of asthma and in those cases of emphysema in which there is definite evidence of associated bronchospasm.The value of the aerosol method of administering chemotherapeutic and antibiotic drugs has probably been overrated, and it is suspected that much of the benefit previously attributed to the therapeutic agent was actually a result of humidification and liquefaction.
