An application of the concept of the therapeutic alliance to sadomasochistic pathology.

This paper traces the history of the therapeutic alliance concept, examining how it has been used and misused, at times elevated to a central position and at others rejected altogether. The loss of this concept created a vacuum in classical psychoanalysis that has been filled by rival theories. The continuing usefulness of looking at the treatment process through the lens of the therapeutic alliance, particularly in relation to the manifold difficulties of working with sadomasochistic pathology, is suggested. To this end, revisions of the theory of the therapeutic alliance are suggested to address some of the difficulties that have arisen in conceptualizing this aspect of the therapeutic relationship, and to provide an integrated dynamic model for working with patients at each phase of treatment. This revised model acknowledges the complexity of the domain and encompasses the multiple tasks, functions, partners, and treatment phases involved. The utility of the revised theory is illustrated in application to understanding the sadomasochistic, omnipotent resistances of a female patient through the phases of her analysis.

Mutational analysis of Smad3, a candidate tumor suppressor implicated in TGF-beta and menin pathways, in parathyroid adenomas and enteropancreatic endocrine tumors.

Based upon molecular allelotyping and comparative genomic hybridization studies, chromosome 15q is the likely location of a tumor suppressor gene important in the pathogeneses of sporadic enteropancreatic endocrine tumors and parathyroid adenomas. Interest has focused on Smad3 as a candidate endocrine tumor suppressor gene because 1) it is localized to 15q and 2) it encodes a TGF beta signaling molecule that has been identified as a binding partner of the multiple endocrine neoplasm type 1 gene product menin, itself involved in enteropancreatic and parathyroid neoplasia. To determine whether Smad3 plays a primary role in development of these tumors, 20 enteropancreatic tumors and 67 parathyroid adenomas were investigated for loss of heterozygosity at DNA markers surrounding Smad3. Twenty percent of enteropancreatic tumors and 24% of parathyroid adenomas showed loss. All 9 coding exons and intron-exon boundaries of the Smad3 gene were then sequenced in genomic DNA from all 20 enteropancreatic and 25 parathyroid tumors, including every case with loss of heterozygosity. No acquired clonal mutations, insertions, or microdeletions in Smad3 were detected in any tumors. Because inactivating somatic mutation is the hallmark of an authentic tumor suppressor, Smad3 is unlikely to function as a classical tumor suppressor gene in the pathogenesis of sporadic parathyroid or enteropancreatic endocrine tumors.

Factors associated with female condom use among HIV-seropositive women.

Female condoms are an effective option for preventing sexually transmitted diseases (STDs), including HIV transmission. Little is known, however, about female condom use in women living with HIV/AIDS. Ninety HIV-positive women completed measures of demographic characteristics, exposure and use of female condoms, attitudes toward female and male condoms, sexual behaviours, and substance use. Most women (77%) had been exposed to female condoms, however only 30% reported lifetime use, 16% reported recent use, and only 6% of the sample used female condoms as much or more than they used male condoms. The only factors consistently associated with female condom use were positive attitudes toward female condoms. Women who recently used female condoms were also more likely to have multiple male sex partners and reported fewer unprotected intercourse occasions. Female condoms are therefore used by a small number of HIV-infected women, particularly those with more than one male sex partner. Female condom use may be enhanced by removing barriers to their use, increasing cooperation of male partners, and enhancing proficiency of use.

Variables influencing condom use in a cohort of gay and bisexual men.

Nine hundred fifty-five of 1,384 (69 per cent) gay and bisexual men enrolled in a prospective study of the natural history of human immunodeficiency virus (HIV) infection who reported engaging in anal intercourse in the past six months were surveyed about condom use practices for both insertive (IAI) and receptive anal intercourse (RAI). The following results were obtained: 23 per cent of the men reported that they always used condoms for IAI and 21 per cent for RAI; 32 per cent sometimes used condoms for IAI; 28 per cent sometimes used condoms for RAI; 45 per cent never used condoms for IAI; and 50 per cent never used condoms for RAI. Multiple logistic regression analysis revealed that the following variables were associated with both insertive and receptive condom use: condom acceptability; a history of multiple and/or anonymous partners in the past six months, and the number of partners with whom one is "high" (drugs/alcohol) during sex. Knowledge of positive HIV serostatus was more strongly associated with receptive than with insertive use. Condom use is a relatively complex health-related behavior, and condom promotion programs should not limit themselves to stressing the dangers of unprotected intercourse.

GRID: a novel Grb-2-related adapter protein that interacts with the activated T cell costimulatory receptor CD28.

Adapter proteins such as Grb2 play a central role in the formation of signaling complexes through their association with multiple protein binding partners. These interactions are mediated by specialized domains such as the well-characterized Src homology SH2 and SH3 motifs. Using yeast three-hybrid technology, we have identified a novel adapter protein, expressed predominantly in T lymphocytes, that associates with the activated form of the costimulatory receptor, CD28. The protein is a member of the Grb2 family of adapter proteins and contains an SH3-SH2-SH3 domain structure. A unique glutamine/proline-rich domain (insert domain) of unknown function is situated between the SH2 and N-terminal SH3 domains. We term this protein GRID for Grb2-related protein with insert domain. GRID coimmunoprecipitates with CD28 from Jurkat cell lysates following activation of CD28. Using mutants of CD28 and GRID, we demonstrate that interaction between the proteins is dependent on phosphorylation of CD28 at tyrosine 173 and integrity of the GRID SH2 domain, although there are also subsidiary stabilizing contacts between the PXXP motifs of CD28 and the GRID C-terminal SH3 domain. In addition to CD28, GRID interacts with a number of other T cell signaling proteins, including SLP-76 (SH2 domain-containing leukocyte protein of 76 kDa), p62dok, and RACK-1 (receptor for activated protein kinase C-1). These findings suggest that GRID functions as an adapter protein in the CD28-mediated costimulatory pathway in T cells.

p53 transcriptional activation domain: a molecular chameleon?

The recent structure of human replication protein A (RPA) bound to residues 38-58 of tumor suppressor p53 exemplifies several important features of protein-protein interactions involved in transcription and DNA repair. First, the N-terminal transcriptional activation domain (TAD) of p53 is multifunctional and dynamic, showing multiple interactions with partner proteins some of which are modulated by phosphorylation. Second, the binding of partner proteins is coupled with a disorder-to-order transition common to many other transcriptional activation domains. Third, the molecular features of p53 residues 47-58 imitate those of single stranded DNA in their interaction with the oligonucleotide oliogsaccharide-binding (OB) fold of the N-terminal domain of RPA70. This regulated association is implicated in transmitting the DNA damage signal to the p53 pathway of stress response. Here we review the recently reported crystal structure of the p53/RPA70N complex and the mechanism by which ssDNA can provide positive feedback to dissociate p53/RPA complexes. The binding mode and regulatory mechanisms of the p53/RPA70N interaction may represent a general paradigm for regulation of the OB folds involved in DNA repair and metabolism.

Risk behaviours associated with urethritis in prison inmates, Sindh.

OBJECTIVE: To identify sexual risk behaviours associated with lifetime risk of urethritis in prison inmates. DESIGN: A cross-sectional study using a pre-designed questionnaire. SETTING: Fourteen prisons throughout the Sindh Province, Pakistan. SUBJECTS: Three thousand three hundred ninety-five prison inmates incarcerated during July, 1994. MAIN OUTCOME MEASURE: Lifetime risk of urethritis occurrence (whether or not the subject was ever affected with urethritis up to his present age) RESULTS: Lifetime risk of urethritis occurrence in the study population was 20.8% (706/3395). The final multivariate logistic regression model indicated that risk behaviours associated with lifetime risk of urethritis in this population were 'sexual intercourse with a female' (adjusted OR = 2.18; 95% CI 1.60, 2.95), 'multiple female sexual partners' (adjusted OR = 1.67; 95% CI 1.28, 2.18) and 'sexual intercourse with man' (adjusted OR = 2.75; 95% CI 2.29, 3.31). CONCLUSION: The prevalence of urethritis in this population was very high. High prevalence of various risky sexual behaviours among inmates indicates, their unawareness as to what precautions they might take to avoid risk of acquiring STDs including HIV. The study subjects meet the characteristics of a core group of STDs transmitters and provides short window of opportunity for STD/HIV control programs to intervene, while they are in detention to reduce the risk not only for this group but also for general population.

Adapting the CAUSN accreditation process for emerging models of nursing education in Canada.

This paper highlights the accreditation issues raised by new and emerging models of baccalaureate nursing education and program delivery in Canada. It suggests ways of adapting the accreditation process to address recent changes. Nursing degree programs now offered by universities include programs at several sites, collaborative programs with partner institutions at multiple sites, and programs offered primarily through distance education. The accreditation program developed by the Canadian Association of University Schools of Nursing (CAUSN) provides a mechanism for monitoring the quality of a nursing education program and promoting the growth of the school that offers the program. Since the decision to undergo accreditation signifies a major commitment on the part of a nursing program, it is essential that the accreditation process be adaptable to meet the needs of evolving nursing education and program delivery models, and that it be fair, equitable, and credible.

Is sexual abuse in childhood or adolescence a predisposing factor for HIV infection during adolescence?

This exploratory study was conducted to determine whether sexual abuse might be a risk factor or marker for other risk factors for Human Immunodeficiency Virus (HIV) infection. Twenty-five HIV-positive adolescents were assessed for a variety of possible risk factors for HIV infection, including prior history of sexual abuse. Fifteen (60%) had a history of sexual abuse. A history of sexual abuse may be a risk factor for HIV infection directly, or it may be associated with or predispose one to other risk factors. The latter mechanism may be related to the long-term negative outcomes of some individuals with a history of sexual abuse. These may include same-sex sexual experiences as an adolescent, re-victimization with additional episodes of abuse, multiple consensual sexual partners, and drug and/or alcohol abuse. Preventive interventions aimed at reducing the risk of HIV infection must take a history of sexual abuse into account. Patients with such a history deserve intensive psychological counseling to help prevent adverse behavioral outcomes that can result in HIV infection.

Genital HPV: links to cervical cancer, treatment, and prevention.

Human papillomavirus is one of the most prevalent sexually transmitted viruses. It consists of over 230 different subtypes and infects the squamous epithelial cells in humans producing cutaneous, mucosal, and epidermodysplasia verruciformis type infections. There are several risk factors for human papillomavirus infections. These include a sexually active life-style beginning at a young age, having multiple lifetime sex partners, having sex with a partner with genital warts, and long term oral contraceptive use. Approximately 80% of sexually active individuals acquire the virus in their lifetime. Clinical and laboratory detection of the virus consists of macroscopic, serologic, and molecular techniques. Although removal of the lesions is preferable, treatment of human papillomavirus infections may include cryotherapy, loop electrosurgical excision procedure, laser surgery, and drug therapy. Certain human papillomavirus subtypes, particularly human papillomavirus 16, have been linked to cervical cancer, therefore, prophylactic and therapeutic vaccines are currently being developed to prevent or fight the virus.

Implementing recommendations for the early detection of breast and cervical cancer among low-income women.

SCOPE OF THE PROBLEM: Among U.S. women, breast cancer is the most commonly diagnosed cancer and remains second only to lung cancer as a cause of cancer-related mortality. The American Cancer Society (ACS) estimates that 182,800 new cases of female breast cancer and 41,200 deaths from breast cancer will occur in 2000. Since the 1950s, the incidence of invasive cervical cancer and mortality from this disease have decreased substantially; much of the decline is attributed to widespread use of the Papanicolaou (Pap) test. ACS estimates that 12,800 new cases of invasive cervical cancer will be diagnosed, and 4,600 deaths from this disease will occur in the United States in 2000. ETIOLOGIC FACTORS: The risk for breast cancer increases with advancing age; other risk factors include personal or family history of breast cancer, certain benign breast diseases, early age at menarche, late age at menopause, white race, nulliparity, and igher socioeconomic status. Risk factors for cervical cancer include certain human papilloma virus infections, early age at first intercourse, multiple male sex partners, a history of sexually transmitted diseases, and low socioeconomic status. Black, Hispanic, or American Indian racial/ethnic background is considered a risk factor because cervical cancer detection and death rates are higher among these women. RECOMMENDATIONS FOR PREVENTION: Because studies of the etiology of breast cancer have failed to identify feasible primary prevention strategies suitable for use in the general population, reducing mortality from breast cancer through early detection has become a high priority. The potential for reducing death rates from breast cancer is contingent on increasing mammography screening rates and subsequently detecting the disease at an early stage--when more treatment options are available and survival rates are higher. Effective control of cervical cancer depends primarily on early detection of precancerous lesions through use of the Papanicolaou test, followed by timely evaluation and treatment. Thus, the intended outcome of cervical cancer screening differs from that of breast cancer screening. In 1991, the National Breast and Cervical Cancer Early Detection Program (NBCCEDP) was implemented to increase breast and cervical cancer screening among uninsured, low-income women. RESEARCH AGENDA: To support recommended priority activities for NBCCEDP, CDC has developed a research agenda comprising six priorities. These six priorities are a) determining effective strategies to communicate changes in NBCCEDP policy to cancer screening providers and women enrolled in the program; b) identifying effective strategies to increase the proportion of enrolled women who complete routine breast and cervical cancer rescreening according to NBCCEDP policy; c) identifying effective strategies to increase NBCCEDP enrollment among eligible women who have never received breast or cervical cancerscreening; d) evaluating variations in clinical practice patterns among providers of NBCCEDP screening services; e) determining optimal models for providing case-management services to women in NBCCEDP who have an abnormal screening result, precancerous breast or cervical lesion, or a diagnosis of cancer; and f) conducting economic analyses to determine costs of providing screening services in NBCCEDP. CONCLUSION: The NBCCEDP, through federal, state, territorial, and tribal governments, in collaboration with national and community-based organizations, has increased access to breast and cervical cancer screening among low-income and uninsured women. This initiative enabled the United States to make substantial progress toward achieving the Healthy People 2000 objectives for breast and cervical cancer control among racial/ethnic minorities and persons who are medically underserved. A continuing challenge for the future is to increase national commitment to providing screening services for all eligible uninsured women to ultimately reduce morbidity and mortality from breast and cervical cancer.

Pap testing and direct immunofluorescence for Chlamydia trachomatis infection in pregnant women.

The aim of the study was to determine the potential for both Pap testing and direct immunofluorescence assay for detection of chlamydia trachomatis infection in pregnant women. A total of 351 pregnant women (first to second trimesters; age range: 15-30 years) were recruited. The background data relating to social and marital status, age, anamnestic data were recorded. Serum samples were tested for IgM antibodies specific to Chlamydia trachomatis by ELISA. Cervical Pap smears were stained by Papanicolaou and direct immunofluorescence. In the present study the overall rate of C. trachomatis infections in pregnant women was 33%. Pap testing suggested a diagnosis of chlamydia trachomatis infection in 8.5% of cases only, direct fluorescence showed positivity in all patients. The highest incidence of unmarried status was recorded in the patients with mixed chlamydial infection and trichomoniasis, also with chlamydial monoinfection, rare visits to the gynecologists were common in patients with mixed chlamydial infection and trichomoniasis, mixed chlamydial and HPV infections, also with chlamydial monoinfection, multiple lifetime sex partners were reported by the patients with combined chlamydial infection and trichomoniasis, also with chlamydial monoinfection. The prevalence of asymptomatic C. trachomatis infection was lower in women with mixed non-viral infections. The incidence of pelvic inflammatory disease was higher in the patients with mixed chlamydial infection and trichomoniasis, mixed chlamydial and HPV infections, and chlamydial monoinfection, incidence of spontaneous abortions was higher in the patients with mixed chlamydial and HSV infections, also with chlamydial monoinfection, incidence of ectopic pregnancy was higher in the patients with mixed chlamydial infection and trichomoniasis, also with mixed chlamydial and HPV infections. Chlamydial infection including cervicitis was frequently diagnosed in women with mixed chlamydial and HSV infections, also with chlamydial monoinfection.

[Properties and transmission of the AIDS virus].

The acquired immunodeficiency syndrome (AIDS) is caused by a retrovirus. LAV/HTLV-III is mainly transmitted by blood and sperm. More than 90% of the newly infected persons belong to four risk groups: male homosexuals, drug addicts, persons with multiple changing sex partners, and bisexuals. Infected individuals carry the virus and antiviral antibodies simultaneously in their blood. The antibodies can be demonstrated by the ELISA and immunofluorescence tests, but positive and questionable test results must be confirmed by the immunoblot. Not all of the persons carrying the virus will develop clinical symptoms, but the percentage of those suffering from severe illnesses rises with time and reaches 40% after 8 years. At present, there is no effective therapy and no vaccine will be ready in the near future. Therefore, it is necessary to take all precautions possible to prevent new infections.

Determinants of human papillomavirus types 16 and 18 infections in the lower female genital tract in an Italian population.

The prevalences of Human Papillomavirus (HPV) types 16 and 18 infection were determined by a non isotopic molecular hybridization assay on cervical scrapes from 738 women affected by gynaecological lesions different from malignancies. The correlation with known epidemiological risk factors for cervical neoplasia, such as sexual habits, smoking and pill use, was investigated. The overall HPV prevalence rate was 29.8% (220/738). Viral DNA sequences were detected in 26.9% (122/452) of morphologically normal cervices, in 75 of 224 HPV lesions (32.5%), in 1 case of 3 HSV2 lesions and in 22 of 59 dysplastic lesions (37.3%), and the frequency was increasing with the severity of CIN from 22.7% of CIN I to 57.1% of CIN III. The most relevant factor as relative risk for the presence of HPV 16/18 was the multiple lifetime sexual partners, whereas the other investigated factors were mainly associated with the clinically manifested HPV infection.

HIV-1 and HTLV-I in sexually transmitted disease clinics in the Dominican Republic.

A cross-sectional seroprevalence study of human immunodeficiency virus type 1 (HIV-1) and human T-cell lymphotropic virus type I (HTLV-I) was undertaken among 494 attendees in two Santo Domingo sexually transmitted disease clinics in 1989. All participants were evaluated for Neisseria gonorrhoeae, Chlamydia trachomatis, syphilis, and genital ulcers. Of the 494 participants, 15 (3.0%) were positive for HIV-1 and 14 (2.8%) were positive for HTLV-I. Twelve of 371 (3.2%) men were HIV-1 seropositive: 0 of 68 homosexual/bisexual and 12 (4.0%) of 302 heterosexual men (one seronegative male could not be classified). Three (2.4%) of 123 women were HIV-1 seropositive. One (1.5%) homosexual/bisexual man, five (1.7%) heterosexual men, and eight (6.5%) women were HTLV-I seropositive. Among heterosexual men, HIV-1 was associated with multiple lifetime sex partners (O.R. = 5.9; 95% C.I. = 1.4, 23; p = 0.007). HIV-1 was associated with genital ulcer disease among women (p = 0.004). Among women, HTLV-I was associated with professional sex work (O.R. = 18; 95% C.I. = 2.1, > 100; p = 0.001). These findings suggest the need for control of sexually transmitted diseases and targeted educational programs for prevention of HIV-1 and HTLV-I among individuals with high-risk behaviors in the Dominican Republic.

[Epidemiology of cervical and endometrial cancer].

In 1995, in France, the estimation of the cervix cancer incidence, with 3,300 new cases, is of 10.3 per 100,000, and the incidence of the endometrial cancer with 3,268 new cases, is of 13.8 per 100,000. The decrease of the incidence of the cervical cancer is of more than 50%, in 1975, the incidence was of 22.4 per 100,000. For the endometrial cancer, the decrease is insignificant, as in 1975, the incidence was of 14.4 per 100,000. This phenomenon has been observed in most european countries. The incidence of the adenocarcinoma of the cervix remains stable. The relative survival at 5 years, at all ages in the French cancer registry of Bas-Rhin is of 65% for the cervical cancer and of 73% for the corpus uteri cancer. However, no improvement has been observed since 1975. The risk factors are quite well-known concerning the cervical cancer, there is a strong correlation with the sexual activities, age at first intercourse, the multiplicity of the partners, which clearly shows that the cervical cancer is a sexually transmitted disease. Concerning the endometrial cancer, the risk factors are mostly linked with the reproductive life: age at menarche, parity, age at first birth, menstrual irregularities, infertility and menopause.

Contribution of variants in the small heterodimer partner gene to birthweight, adiposity, and insulin levels: mutational analysis and association studies in multiple populations.

Loss of function mutations in the small heterodimer partner (SHP) gene have been reported to cause obesity and increased birth weight. We examined the relation between genetic variation in SHP and birth weight, adiposity, and insulin levels in three independent populations. The coding regions and 562 bases of the SHP promoter were screened for mutations in 329 subjects with severe early-onset obesity. Two novel missense mutations, R34G and R36C, were identified; these were not found in control subjects and did not cosegregate with obesity in family studies. Two common polymorphisms, G171A and -195CTGAdel, were found in 12 and 16% of subjects, respectively. Within the obese cohort, G171A and -195CTGAdel carriers had higher and lower birth weights, respectively, than wild-type subjects, the rare homozygotes for G171A being particularly large at birth. In a U.K. population-based cohort of 1,079 children, the 171A allele was associated with higher BMI (P < 0.05) and waist circumference (P = 0.001). Children carrying the G171A variant had higher 30-min insulin responses to a glucose load (P = 0.03). In conclusion, although mutations in SHP are not a common cause of severe human obesity, genetic variation in the SHP locus may influence birth weight and have effects on BMI, possibly through effects on insulin secretion.
