[source] Primary care health issues among men who have sex with menJOURNAL OF THE AMERICAN ACADEMY OF NURSE PRACTITIONERS, Issue 4 2006Royal Gee MSN Abstract Purpose: The purpose of the article is to examine "appropriate" health care for men who have sex with men (MSM), which is not to suggest "special" health care. As a group, MSM are at increased risk for sexually transmitted infections, anal cancer, and mental health disorders. Focus areas in this article will address health issues that the primary care nurse practitioner (NP) may encounter in clinical practice: anal carcinoma, sexually transmitted diseases (STDs), high-risk sexual practices, depression, and substance abuse were topics chosen for inclusion in this article. These topics were among those highlighted in the Healthy People 2010 Companion Document for LGBT Health, which served to examine the healthcare disparities and lack of access to needed services related to sexual orientation. Data source: Extensive literature review of research articles, journals, clinical practice guidelines, books, and public health department Internet Web sites. Conclusions: There are unique health disparities that exist for MSM related to social, emotional, and mental health factors, in addition to physical issues such as STDs. There is an increasing need for primary care providers to be aware of these disparities, as well as the factors that influence these disparities, in order to provide multidimensional care and health counseling that is unique to NP practice. Implications for practice: Both the primary care NP and the patient should be aware of the unique healthcare issues among MSM that should be incorporated into the patient's routine health maintenance program. As primary care providers, it is within the standards of practice for NPs to provide culturally competent care, along with health promotion and disease prevention for MSM. [source] Epidermoid anal cancer prognosis comparison among HIV+ and HIV, patientsALIMENTARY PHARMACOLOGY & THERAPEUTICS, Issue 4 2009L. ABRAMOWITZ Summary Background, Previous studies suggest a poor prognosis of epidermoid anal cancer in HIV+ patients. Aim, To investigate the long-term outcome of epidermoid anal cancer in HIV+ and HIV, patients in the highly active antiretroviral treatment (HAART) era. Methods, We included all patients with epidermoid anal cancer referred to six hospitals from 1998 to 2004. Results, In all, 151 patients (44 HIV+, 107 HIV,) were reviewed retrospectively for 27 (median of 16,44) months. HIV+ patients were male (100% vs. 27%, P < 0.001) and younger (45 vs. 62 years old, P < 0.001) than HIV, patients. No significant differences were observed in the tumour stage, pelvic radiotherapy dose or concomitant chemotherapy, according to the HIV status. After chemoradiotherapy, similar numbers of HIV+ and HIV, patients had grade III-IV toxicity. A complete response was obtained in 82% and 75% (N.S.) of cases, respectively. The disease-free survival rates were 77% and 67% (N.S.) and the overall survival rates were 85% and 84% (N.S.), respectively, after 3 years of follow-up. Duration of HIV infection, viral load and CD4 count had no effect on the survival rate of HIV+ patients with EAC. Conclusions, The clinical outcome of HIV+ patients with epidermoid anal cancer is similar to that of HIV, patients. Therefore, the same therapeutic guidelines should be applied to both populations.

The report suggests that the expansion of primary-care centres and the increasing complexity of care they offer mean that community pharmacists will increasingly need to take on some GP roles. It foresees an increase in shared premises and calls for closer interdisciplinary working between GPs, pharmacists and nurses. Variation in PCT commissioning of enhanced services from pharmacies has resulted in ,a fragmented system of postcode pharmaceutical care rationing'. Full read-write access to patients' records will be essential if the benefits of electronic prescribing are to be realised. How pharmacists can support commissioners The NHS Alliance and Primary Care Pharmacists' Association have published a guide for practice-based commissioners on making the most of primary-care pharmacists. Prescribing Support and Prescribing Advice for Practice Based Commissioners , A Guide for Commissioning Groups and GPs illustrates how pharmacists can support commissioners at all levels of medicines use.

Directory website aids diabetes management The National Diabetes Support Team is developing a website that brings together different datasets and tools for diabetes management. The Diabetes Data Directory (www.yhpho.org.uk/diabetesdatadirectory/introddd.asp) summarises what other online databases can provide and lists the tools that can be used to answer specific questions. The first edition is now online, providing direct links to the appropriate sites. Flu vaccine efficacy in older people challenged US reviewers have questioned the effectiveness of flu vaccine in older people (Lancet Infect Dis online: 24 September; doi: 10.1016/ S1473-3099(07)70236-0). They were unable to confirm a reduction in flu mortality since 1980, concluding that biased patient selection and nonspecific end-points such as all-cause mortality may have exaggerated the benefits of vaccination in clinical trials. The Department of Health is encouraging younger people in at-risk groups to be vaccinated against flu this winter; last year, 58 per cent of under-65s at risk were not vaccinated. OC cervical cancer risk probably overestimated Recent evidence that oral contraceptives may be associated with a small increase in the incidence of cervical cancer probably overestimates the risk, says the Clinical Effectiveness Unit of the Faculty of Family Planning and Reproductive Health Care (www.ffprhc.org.uk). A recent study in the BMJ reported a 12 per cent reduced overall risk of cancer associated with oral contraceptives but an increased risk of cervical cancer of 38 per 100 000 woman-years after at least eight years' use. The FFPRHC says this study was conducted before the UK cervical screening programme was established, and at a time when the average Inhaled insulin ,unlikely to be cost effective' Inhaled insulin (Exubera) is safe and effective but costs so much more than injected insulin that it is unlikely to be cost effective, according to a new Health Technology Assessment (2007;11:No.33.www.hta.nhsweb.nhs.uk). The review included nine trials (seven of Exubera), in which the only significant difference between inhaled and injected soluble insulin was in patient preference. However, most of the trials used syringes for insulin injection rather than pens. The extra cost of inhaled insulin is put at between £600 and £1000 per year. New topics for NICE The Secretary of State for Health has referred the novel antihypertensive aliskiren (Rasilez) for appraisal by NICE; aliskiren is the first direct renin inhibitor to be introduced. Other referrals to NICE include five clinical guidelines (multiple pregnancy, transient loss of consciousness, lower UTI in men, post-ITU rehabilitation and colorectal and anal cancer). Topics for technology appraisals include cetuximab (Erbitux) for colorectal and head and neck cancers. QOF statistics for 06/07 GPs in England averaged 96.3 per cent of the maximum points available for the clinical domain of the Quality and Outcomes Framework in 2006/07 compared with 97.1 per cent previously, official statistics show. Mean practice scores for most clinical areas were in the mid-90 per cent range, but highest for obesity (100 per cent) and lowest for depression (81 per cent), palliative care (90 per cent), mental health and epilepsy (<95 per cent). NICE consulting on type 2 diabetes guideline NICE is consulting on its draft clinical guideline for the management of type 2 diabetes. Comments should be submitted online by 22 November; publication is scheduled for April 2008. The drug of first choice for glycaemic control is metformin, which should be considered even for patients who are not overweight; a sulphonylurea is an alternative or adjunctive agent if glycaemic control is not achieved with metformin alone. If these regimens fail, a glitazone may be added. Exenatide (Byetta) is recommended only for obese patients for whom other oral treatments have failed. The guidance will update and replace clinical guidelines E, F, G and H, and technology appraisals 53, 60 and 63. Glitazones increase risk of HF but not CV death A new meta-analysis , this time of seven trials involving a total of 20 191 patients with type 2 diabetes or impaired glucose tolerance treated with a glitazone , has concluded that these agents are associated with an increased risk of heart failure but not cardiovascular death (Lancet 2007;370:1129,36). Compared with comparator drugs, glitazones were associated with an increased risk of congestive heart failure (2.3 vs 1.4 per cent; relative risk, RR, 1.72; number needed to harm over 30 months, 107). There was no heterogeneity between studies, showing that this is a class effect. However, the risk of cardiovascular death was not increased for either rosiglitazone (Avandia) or pioglitazone (Actos).

Collett An increased incidence of malignancy is an established complication of organ transplantation and the associated immunosuppression. In this study on cancer incidence in solid organ transplant recipients in Britain, we describe the incidence of de novo cancers in the allograft recipient, and compare these incidences following the transplantation of different organs. Data in the UK Transplant Registry held by NHS Blood and Transplant (NHSBT) were linked with data made available by the cancer registries in England, Scotland and Wales. Incidence rates in the transplanted population were then compared with the general population, using standardized incidence ratios matched for age, gender and time period. The 10-year incidence of de novo cancer in transplant recipients is twice that of the general population, with the incidence of nonmelanoma skin cancer being 13 times greater. Nonmelanoma skin cancer, cancer of the lip, posttransplant lymphoproliferative disease and anal cancer have the largest standardized incidence ratios, but the incidence of different types of malignancy differs according to the organ transplanted. Patterns in standardized incidence ratios over time since transplantation are different for different types of transplant recipient, as well as for different malignancies. These results have implications for a national screening program. [source] MALIGNANT PROGRESSION OF ANAL INTRA-EPITHELIAL NEOPLASIAANZ JOURNAL OF SURGERY, Issue 8 2006Angus J. M. Watson Background: Anal intra-epithelial neoplasia (AIN) is believed to be a precursor to squamous cell carcinoma of the anus. The risk of developing anal cancer in patients with AIN, although known to occur, has been thought to be relatively low. This study reviews our experience with AIN, reviewing the incidence and risk factors for development of invasive malignancy and the outcome of present management strategies. Methods: This study examined a cohort of 72 patients identified from a prospective database with AIN from a single institution between January 1996 and December 2004. A single pathologist examined all pathological specimens. Results: There were 72 patients (52 women) and the median age was 49 years (range, 18,81 years). We identified progression of AIN to invasive malignancy in eight patients despite undergoing surveillance. Regression following treatment or biopsy was seen in 25 patients. Four patients required stomas for incontinence following treatment. Conclusion: This study has shown a high rate of progression to invasive malignancy (11%) with AIN despite surveillance. The patients at risk of developing squamous cell carcinoma were the immunocompromised and those with genital intra-epithelial field change. Treatment of AIN has significant complications and despite treatment, invasive cancers do occur. Decisions made for treatment of AIN can affect treatment choices if invasive malignancy develops. [source] Anal intraepithelial neoplasia and anal cancer in dermatological practiceAUSTRALASIAN JOURNAL OF DERMATOLOGY, Issue 3 2007Asoka Herat SUMMARY Anal intraepithelial neoplasia is considered to be a precursor lesion of invasive anal cancer. It is now increasingly recognized in high-risk groups, such as men who have sex with men and HIV-infected patients. Human papillomaviruses are considered to be an important aetiological agent in both anal intraepithelial neoplasia and anal cancer. Dermatologists are likely to encounter these conditions among the differential diagnoses to be considered in high-risk patients presenting with perianal and anal lesions. Anal cancer rates are also increasing among the HIV-infected and HIV-non-infected population. The successful treatment of anal intraepithelial neoplasia may reduce the risk of subsequent development of anal cancer. However, current therapies for anal intraepithelial neoplasia may be associated with treatment-related morbidity and are not well validated. It is currently not proven that they reduce the likelihood of the development of anal cancer. Nevertheless, screening for anal intraepithelial neoplasia is being advocated for high-risk groups and may become standard dermatological care for these patients. In view of recent developments in the understanding of this condition, this article reviews the current understanding of anal intraepithelial neoplasia and its treatment from a dermatological perspective. [source] Primary rectus abdominis myocutaneous flap for repair of perineal and vaginal defects after extended abdominoperineal resectionBRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 4 2005S. W. Bell Background: Significant morbidity can result from perineal wounds, particularly after radiotherapy and extensive resection for cancer. Myocutaneous flaps have been used to improve healing. The purpose of this study was to evaluate the morbidity and results of primary rectus abdominis myocutaneous flap reconstruction of the vagina and perineum after extended abdominoperineal resection. Methods: Thirty-one consecutive patients undergoing one-stage rectus abdominis myocutaneous flap reconstruction of extensive perineal wounds were studied prospectively. Twenty-six patients had surgery for recurrent or persistent epidermoid anal cancer or low rectal cancer, and 21 had high-dose preoperative radiotherapy. Results: Three weeks after the operation, complete healing of the perineal wound was seen in 27 of the 31 patients. There were nine flap-related complications including three patients with partial flap necrosis, two with vaginal stenosis, one with vaginal scarring, one with small flap disunion and two with weakness of the anterior abdominal wall. There were no unhealed wounds at the completion of follow-up (median 9 months). Conclusion: The transpelvic rectus abdominis myocutaneous flap for the reconstruction of large perineal and vaginal wounds achieves wound healing with only moderate morbidity in the majority of patients after extensive abdominoperineal resection with or without radiotherapy.

[source] Prognostic factors derived from a prospective database dictate clinical biology of anal cancerCANCER, Issue 17 2010The intergroup trial (RTOG 98-11) Abstract BACKGROUND: Only 4 prospective randomized phase 3 trials have been reported for anal cancer. A prognostic factor analysis for anal cancer from a prospective database has been published from only 1 study (N = 110). To confirm and uncover new prognostic factors, we analyzed the prospective database of intergroup RTOG 98-11. METHODS: Univariate and multivariate analyses of the baseline characteristics for 5-year overall survival (OS) and disease-free survival (DFS) were carried out. Various combinations of tumor diameter and clinically positive nodes (N+) were analyzed to identify subgroups. RESULTS: A total of 644 were assessable and analyzed. Tumor diameter >5 cm was associated with poorer 5-year DFS (P = .0003) and poorer 5-year OS (P = .0031), and N+ was associated with poorer 5-year DFS (P , .0001) and poorer 5-year OS (P = , .0001) in the multivariate analysis. In stratified analyses, N+ had more adverse influence on DFS and OS than did tumor diameter. Patients with >5-cm tumor and N+ had the worst DFS (only 30% at 3 years compared with 74% for the best group; <5 cm primary and N0) and OS (only 48% at 4 years compared with 81% for the best group; <5 cm primary and N0). Men had worse DFS (P = .02) and OS (P = .016). These factors maintained their influence in each treatment arm. CONCLUSIONS: This prospective prognostic factor analysis establishes tumor diameter as an independent prognosticator of poorer 5-year DFS and OS and confirms N+ and male sex as poor prognostic factors. This analysis also uncovers novel subgroups (derived from combining prognostic factors) with incremental worsening of DFS and OS. Cancer 2010. © 2010 American Cancer Society. [source] Examining the association between socioeconomic status and potential human papillomavirus-associated cancers,,§CANCER, Issue S10 2008Vicki B. Benard PhD Abstract BACKGROUND. This study examined the association between county-level measures of socioeconomic status (SES) and the incidence rate of human papillomavirus(HPV)-associated cancers, including cervical, vulvar, vaginal, anal, penile, and oral cavity and oropharyngeal cancers. METHODS. The authors collected data from cancer registries for site-specific invasive cancer diagnoses between 1998 and 2003, inclusive, among adults aged >20 years at the time of diagnosis. County-level variables that included education, income, and poverty status were used as factors for socioeconomic status. Measures of rural-urban status, the percentage of the population that currently smoked, and the percentage of women who reported having ever had a Papanicolaou (Pap) test were also studied. RESULTS. Lower education and higher poverty were found to be associated with increased penile, cervical, and vaginal invasive cancer incidence rates. Higher education was associated with increased incidence of vulvar cancer, male and female anal cancer, and male and female oral cavity and oropharyngeal cancers. Race was an independent predictor of the development of these potentially HPV-associated cancers. CONCLUSIONS. These findings illustrate the association between SES variables and the development of HPV-associated cancers. The findings also highlight the importance of considering SES factors when developing policies to increase access to medical care and reduce cancer disparities in the United States.
