Self-reported condom use is associated with reduced risk of chlamydia, gonorrhea, and trichomoniasis

OBJECTIVES: To evaluate the association between self-reported condom use and prevalent and incident chlamydia, gonorrhea, and trichomoniasis. STUDY DESIGN: Prospective study of 414 males attending a sexually transmitted infection (STI) clinic in Jamaica. Condom use and STI status were assessed at enrollment and at 4 follow-up visits. RESULTS: The analyses on condom use and prevalent STI included data from 414 men, while those on incident STI were based on 1111 intervals from 355 men. We diagnosed prevalent STI (chlamydia, gonorrhea, and/or trichomoniasis) in 54.6% (n = 226) of the participants at enrollment. About 14% (n = 51) of participants had at least 1 of the study STIs during follow-up. Follow-up visits in which participants reported consistent condom use (100% of acts) for the past 7 days had less incident STI (adjusted OR, 0.4; 95% CI, 0.2-0.9) compared with visits where no condom use was reported. Self-reported condom use was more closely correlated with incident than prevalent STI. For example, the adjusted OR for prevalent infection for participants reporting consistent versus no condom use in past 7 days was 0.7 (95% CI, 0.4-1.2). Classifications based on the number of unprotected acts yielded findings similar to those based on the proportion of acts protected. CONCLUSIONS: Consistent condom use was associated with reduced risk of incident urethral STI. Research on condom effectiveness should focus on incident STI outcomes, where the temporal relationship between condom use and infection is clearer.     

Does a choice of condoms impact sexually transmitted infection incidence? A randomized, controlled trial

OBJECTIVE: The objective of this study was to assess whether providing a choice of condoms would increase condom acceptability, increase self-reported use, and decrease incident sexually transmitted infection. STUDY: We randomized 414 men presenting with urethral discharge in Jamaica to receive either the "standard" clinic condom or a choice of 4 different types of condoms. Men were treated presumptively at enrollment and followed up at 1, 2, 4, and 6 months. RESULTS: Participants in the choice group had a strong preference (P <0.01) for the most popular condom available in Jamaica. This preference did not translate into higher condom use (P = 0.16). The 6-month cumulative probability of first incidence of gonorrhea, chlamydia, or trichomoniasis was slightly higher in the choice group (21%; 95% confidence interval [CI], 15-28%) versus the control group (17%; 95% CI, 11-23%); the difference in the survival curves was not significant (P = 0.35). CONCLUSION: A choice of condoms may increase perceived acceptability but not lead to increased condom use and subsequently lower sexually transmitted infection rates.     

Pulmonary Sporothrix schenckii infection in a HIV positive child

Sporothrix schenckii is a ubiquitous fungus, causing mostly non life-threatening localized infections of the skin and subcutaneous tissues that can be treated with oral antifungal agents. Meningeal, pulmonary and osteoarticular dissemination occur mainly in immunosuppressed patients. Pulmonary sporotrichosis is rare and responds poorly to treatment. Cases of disseminated sporotrichosis have most frequently been reported in patients residing in South America and Asia, and have increasingly been reported in AIDS patients. The distribution and pathogenicity of S. schenckii in Sub-Saharan Africa is not well known. We report a case of invasive pulmonary sporotrichosis in an eleven year old HIV-infected boy in Kinshasa, Democratic Republic of the Congo, successfully treated with oral fluconazole.     

Psychoanalytic Psychotherapy with Psychotics†

Objective: The frequent co-occurrence of posttraumatic stress disorder (PTSD) and chronic pain has received much attention in the literature. However, the extant literature is limited in that these investigations generally exclude patients with co-occurring substance use disorders (SUD). Thus, the present study investigated symptoms of PTSD and SUD in veterans with high and low pain symptoms. Method: Veterans (N = 136) seeking treatment for comorbid symptoms of PTSD and SUD were recruited as part of a larger study. All participants completed a baseline assessment, which included a series of diagnostic interviews and self-report questionnaires measuring symptoms of pain, PTSD and SUD. Results: Higher levels of self-reported pain were found to be associated with both self-reported and clinician-rated PTSD symptoms above and beyond the influence of the demographic variables. However, no reliable relations were demonstrated between substance use and pain. Conclusions: Although preliminary, the findings highlight the common occurrence of chronic pain among veterans with comorbid PTSD/SUD, and the potential impact of pain on clinical presentation. The findings may help inform special considerations for assessment and treatment practices for this high-risk population.     

Clinical Characteristics Associated with Mycoplasma genitalium among Female Sex Workers in Nairobi,Kenya

The prevalence of Mycoplasma genitalium is high in vulnerable populations of women in low-resource settings. However, the epidemiology of infection in these populations is not well established. To determine the prevalence of Mycoplasma genitalium and its association with cervical cytology and other correlates, we recruited 350 female sex workers (FSW) who were 18 to 50 years old in Nairobi, Kenya, for a cross-sectional study. A questionnaire was administered at baseline to obtain information on sociodemographics and sexual behaviors. Women underwent a pelvic exam, during which a physician collected cervical-exfoliation samples for conventional cytology and sexually transmitted infection (STI) testing. Samples were tested for M. genitalium and other STI organisms (Chlamydia trachomatis, Neisseria gonorrhoeae, Trichomonas vaginalis) and the E6/E7 mRNA of human papillomavirus (HPV) by Aptima nucleic amplification assays. The prevalence of M. genitalium was 12.9%. FSW who engaged in sexual intercourse during menses were less likely to have M. genitalium infection than those who did not (odds ratio [OR], 0.3; 95% confidence interval [95% CI], 0.1, 0.9). M. genitalium was also less prevalent among FSW who had worked in prostitution for >5 years (6.2%) than among those who had worked for <3 years (17.6%) (OR, 0.3; 95% CI, 0.1, 0.8). FSW who reported more frequent condom use were more likely to be infected with M. genitalium than those who reported less frequent use (OR, 3.8; 95% CI, 1.2, 11.6). These correlates differ from those found in M. genitalium studies conducted with FSW from West Africa and China. Further longitudinal analyses assessing associations with persistent M. genitalium infection are needed.     

Adults' perception and production of the English vowel /i/.

This study investigated the link between the perception and production of the English vowel /i/ by adult native speakers of English. Participants first produced the vowel /i/ using normal (citation) and careful (hyperarticulated) speech, then completed a method of adjustment task in which they selected their ideal exemplar of /i/. In this perceptual task, 24 of 35 participants had a prototype; the remaining 11 did not, but were retained for comparison. In keeping with the hyperspace effect (K. Johnson, E. Flemming, & R. Wright, 1993), all participants selected perceptual stimuli with F1 and F2 values that were more extreme (i.e., higher and further forward in the vowel space) than those of their normal, citation productions. An analysis of front-back and high-low qualities for the perceptual and production data in Euclidian space revealed that hyperarticulated speech was closer to the perceptual data than citation speech was, but only for participants with relatively clear-cut prototypes. The basis for such individual variation in perception-production links is discussed.     

Deficient helper cell function as a cause of diminished pokeweed mitogen blastogenic responses in patients with non-Hodgkin's lymphomas

An investigation has been made of immunoregulatory T-cell function in the non-Hodgkin's lymphomas by comparing immunoregulation of healthy control and patient peripheral blood lymphocyte blastogenic responses to pokeweed mitogen. Normal mononuclear leukocytes (MNL) had significantly higher responses than patient MNL. MNL were subsequently separated into T- and non-T-cell fractions by differential E-rosette sedimentation for co-culture experiments. When normal non-T-cells and autologous irradiated T-cells were recombined, the mitogenic response again exceeded the response of patient non-T-cells recombined with their own irradiated T-cells. However, when normal non-T-cells were co-cultured with patient irradiated T-cells, the mitogenic response was diminished. Moreover, when patient non-T-cells were co-cultured with normal irradiated T-cells, a normal proliferative response occurred. These differences in non-T-cell response are not simply a result of allogeneic effects, since normal non-T-cell responses were the same regardless of whether autologous or normal allogeneic irradiated T-cells were used as helpers. Furthermore, co-culture of normal non-T-cells simultaneously with autologous irradiated T-cells and patient irradiated T-cells revealed no diminution of blastogenic response compared with co-cultures of normal non-T-plus autologous irradiated T only, suggesting no net suppression by patient irradiated T-cells. Studies with monoclonal antibodies revealed that patient T-cells had normal to increased ratios of OK-T4+:OK-T8+ cells. These results suggest that peripheral blood T-cells from patients with non-Hodgkin's lymphomas, despite the presence of a normal to increased ratio of OK-T4+:OK-T8+ cells, are functionally deficient in their helper capacity for non-T-cell blastogenic response to pokeweed mitogen. Abnormal helper T-cell function may explain some of the immune deficits in patients with non-Hodgkin's lymphoma and may be important in the pathogenesis of these diseases.     

Effect of metergoline on the diurnal prolactin responses to insulin-induced hypoglycemia in normal men

(1) Insulin tolerance tests were performed at 0900 and 1800 hr on six young healthy men, under basal conditions and after metergoline pretreatment. (2) The hypoglycemia induced by insulin during the two tests was not significantly different. (3) Both morning and evening basal prolactin (PRL) levels were significantly lowered by metergoline. (4) Insulin hypoglycemia-induced PRL release was significantly inhibited by metergoline, both in the morning and in the evening. (5) Although dopaminergic mechanisms may account for these effects of metergoline, serotonergic mechanisms cannot be ruled out.     

The effect of upright tilt on the volume of the failing human left ventricle

The effect of a passive change from supine to 25-degree head-up tilted position on left ventricular volume was studied by echocardiography and other noninvasive techniques in 18 normal subjects, 6 patients with compensated LV volume overloading, and 12 patients with LV failure. In normal subjects and patients with compensated LV volume overloading, 10 minutes of head-up tilt resulted in a significant decrease in the echocardiographic LV internal dimension equivalent to a decrease in the calculated LV end-diastolic volume of 27 and 16 per cent, respectively. In contrast, no change in LV end-diastolic dimension and volume was noted during tilt in the patients with LV failure. The response of heart rate, blood pressure, and LV ejection fraction to this intervention was insignificant in all groups. These data indicate that volume preload is unresponsive to postural changes in patients with LV failure but not in normal subjects or in those with compensated LV volume overloading. It is suggested that the effect of posture on LV volume and output is primarily determined by the absence or presence of LV failure and the consequences of it on the peripheral circulation.
