‘Too much for one day’: a case study of disclosure in the paediatric HIV/AIDS clinic

Background

Despite acknowledgement of the complexity and challenges of the process of disclosure of HIV status to adolescents, little work has been carried out on the communication features which facilitate or hinder the process. This qualitative case study reflects the interactional dynamics of an interaction between caregiver, physician and counsellor around the topic of disclosure in a South African clinic.

Methods

A 40‐minute encounter between a doctor, the grandmother of an adolescent with HIV/AIDS and a counsellor around the process of disclosure was transcribed and examined in detail in relation to its structure, topics, timing and sequence as well as its movement towards a collaborative ending. Analysis was based on elements of conversational and thematic analysis.

Results

The session was characterized by distinct stages and the emergence of multiple voices and perspectives from the participants. The negotiated management of the session sheds light on multiple barriers to care as well as the influence of contextual factors on the process. The important mediating role of the counsellor in the triad emerges. The analysis highlights both unique features of the consultation and common challenges to clinicians when disclosing.

Discussion and Conclusions

The task of disclosure is complex and intricate. Results suggest team processes are critical, as are temporal and contextual factors and the need for an understanding of communication. Implications for the clinic team are discussed and suggestions made for the development of collaborative partnership based on an understanding of roles and responsibilities, time factors and enhancement of features such as trust and communication.     

The Black Esophagus

A dark-pigmented (black) esophagus is a rare observation during the course of upper endnscopy. The differential diagnosis of a black esophagus includes acute necrotizing esophagitis, exogenous dye ingestion, lye in gestion, malignant melanoma, melanosis, and pseudomelanosis esophagi. Many of these conditions are suggested by the history and associated endoscopic findings. In most patients, a biopsy is needed to establish a definitive diagnosis and explanation for the black-appearing esophagus. We describe a patient with a black esophagus encountered during routine endoscopy. The clinical, endoscopic, and histopalhological features of this unusual finding are presented, along with a review of the literature.     

Increasing Endocannabinoid Levels in the Ventral Pallidum Restore Aberrant Dopamine Neuron Activity in the Subchronic PCP Rodent Model of Schizophrenia

Background:

Schizophrenia is a debilitating disorder that affects 1% of the US population. While the exogenous administration of cannabinoids such as tetrahydrocannabinol is reported to exacerbate psychosis in schizophrenia patients, augmenting the levels of endogenous cannabinoids has gained attention as a possible alternative therapy to schizophrenia due to clinical and preclinical observations. Thus, patients with schizophrenia demonstrate an inverse relationship between psychotic symptoms and levels of the endocannabinoid anandamide. In addition, increasing endocannabinoid levels (by blockade of enzymatic degradation) has been reported to attenuate social withdrawal in a preclinical model of schizophrenia. Here we examine the effects of increasing endogenous cannabinoids on dopamine neuron activity in the sub-chronic phencyclidine (PCP) model. Aberrant dopamine system function is thought to underlie the positive symptoms of schizophrenia.

Methods:

Using in vivo extracellular recordings in chloral hydrate–anesthetized rats, we now demonstrate an increase in dopamine neuron population activity in PCP-treated rats.

Results:

Interestingly, endocannabinoid upregulation, induced by URB-597, was able to normalize this aberrant dopamine neuron activity. Furthermore, we provide evidence that the ventral pallidum is the site where URB-597 acts to restore ventral tegmental area activity.

Conclusions:

Taken together, we provide preclinical evidence that augmenting endogenous cannabinoids may be an effective therapy for schizophrenia, acting in part to restore ventral pallidal activity.     

Beliefs about weight and breast cancer: an interview study with high risk women following a 12?month weight loss intervention

Background

Breast cancer is the most common cancer in the UK. Lifestyle factors including excess weight contribute to risk of developing the disease. Whilst the exact links between weight and breast cancer are still emerging, it is imperative to explore how women understand these links and if these beliefs impact on successful behaviour change.

Method

Overweight/obese premenopausal women (aged 35–45) with a family history of breast cancer (lifetime risk 17–40%) were invited to a semi-structured interview following their participation in a 12 month weight loss intervention aimed at reducing their risk of breast cancer. Interviews were carried out with 9 women who successfully achieved ≥5% weight loss and 11 who were unsuccessful. Data were transcribed verbatim and analysed using thematic analysis.

Results

Three themes were developed from the analysis. The first theme how women construct and understand links between weight and breast cancer risk is composed of two subthemes, the construction of weight and breast cancer risk and making sense of weight and breast cancer risk. This theme explores women’s understanding of what contributes to breast cancer risk and whether they believe that weight loss could reduce their breast cancer risk. The second theme motivation and adherence to weight loss interventions explains that breast cancer risk can be a motivating factor for adherence to a weight loss intervention. The final theme, acceptance of personal responsibility for health is composed of two subthemes responsibility for one’s own health and responsibility for family health through making sensible lifestyle choices.

Conclusion

Beliefs about weight and breast cancer risk were informed by social networks, media reports and personal experiences of significant others diagnosed with breast cancer. Our study has highlighted common doubts, anxieties and questions and the importance of providing a credible rationale for weight control and weight loss which addresses individual concerns. Counselling and health education material should be tailored to facilitate understanding of both genetic and modifiable risk factors and should do more help individuals to visualise the weight and breast cancer link.
