Are we able to correctly identify prostate cancer patients who could be adequately treated by focal therapy?

Introduction and Objective: Because of the improvements on detection of early stage prostate cancer over the last decade, focal therapy for localized prostate cancer (PC) has been proposed for patients with low-risk disease. Such treatment would allow the control of cancer, thereby diminishing side effects, such as urinary incontinence and sexual dysfunction, which have an enormous impact on quality of life. The critical issue is whether it is possible to preoperatively predict clinically significant unifocal or unilateral prostate cancer with sufficient accuracy. Our aim is to determine whether there is any preoperative feature that can help select the ideal patient for focal therapy. Material and methods: A total of 599 patients who underwent transrectal ultrasound, (TRUS)-guided prostate biopsy followed by radical prostatectomy to treat PC were examined in our laboratory between 2001 and 2009. We established very restricted criteria to select patients with very-low-risk disease for whom focal therapy would be suitable (only I biopsy core positive, tumor no larger than 80% of a single core, no perineural invasion, PSA serum level < 10 ng/ml, Gleason score < 7 and clinical stage T1c, T2a-b). We defined 2 groups of patients who would be either adequately treated or not treated by focal therapy. The primary endpoint was the evaluation of preoperative features in order to identify which parameters should be considered when choosing good candidates for focal therapy. Results: Fifty-six out of 599 patients met our criteria. The mean age was 59 years, and the mean number of biopsy cores was 14.4. Forty-seven (83.9%) were staged T1c, and 9 (16.1%) were staged T2a-b. Forty-four (78.6%) patients could be considered to have been adequately treated by focal therapy, and 12 (21.4%) could not. There was no statistical difference between the 2 groups considering age, clinical stage, PSA levels, Gleason score, and tumor volume in the biopsy. All 12 patients who could be considered inadequately treated had a bilateral, significant secondary tumor, 58.3% had Gleason >= 7, and 25% were staged pT3. Conclusion: Although focal therapy might be a good option for patients with localized prostate cancer, we are so far unable to select which of them would benefit from it based on preoperative data, even using very restricted criteria, and a considerable proportion of men would still be left undertreated.

Internal iliac artery embolization before endovascular repair of aortoiliac aneurysms with a nitinol vascular occlusion plug

PURPOSE: To evaluate the acute and midterm effectiveness of a novel vascular occlusion device for embolization of the internal iliac artery (IIA) before endovascular repair of aortoiliac aneurysms. MATERIALS AND METHODS: Between March 2005 and April 2006, nine men (mean age, 75 years +/- 5; range, 66-83 y) with aortoiliac aneurysms underwent bifurcated endovascular stent-graft procedures. All these patients were referred specifically for embolization. Pre- and perioperatively, eight patients underwent unilateral embolization and one underwent bilateral embolization of the IIA to prevent type II endoleak. Via a contralateral femoral approach with a 6-F or 8-F sheath, the embolization procedure was performed with an Amplatzer Vascular Plug, a self-expandable cylindrical device consisting of a nitinol-based wire mesh. Technical success, clinical outcome, and complications were evaluated. Follow-up at 3, 6, and 12 months was performed with clinical and radiologic examinations. RESULTS: IIA embolization was technically successful in all cases and no procedure-related complications occurred. Imaging at discharge and at 3-, 6-, or 12-month follow-up was accomplished in all nine patients. Control computed tomography and magnetic resonance angiography did not reveal retrograde perfusion of the aneurysmal sac, ie, type II endoleak. Three of nine patients (33.3%) reported symptoms of buttock claudication that did not resolve completely. Clinical symptoms such as bowel ischemia or sexual dysfunction were not observed. CONCLUSIONS: The midterm results of this study suggest that preoperative IIA embolization with a nitinol vascular occlusion plug during endovascular treatment of aortoiliac aneurysms is safe and effective.

Evaluation of a pilot diabetes educational intervention using the American Diabetes Association's Risk Assessment form with the patrons of The Health Museum, Houston Texas

Diabetes Mellitus is not a disease, but a group of diseases. Common to all types of diabetes is high levels of blood glucose produced from a variety of causes. In 2006, the American Diabetes Association ranked diabetes as the fifth leading cause of death in the United States. The complications and consequences are serious and include nephropathy, retinopathy, neuropathy, heart disease, amputations, pregnancy complications, sexual dysfunction, biochemical imbalances, susceptibility and sensitivity to many other diseases and in some cases death. ^ The serious nature of diabetes mellitus and its complications has compelled researchers to devise new strategies to reach population segments at high risk. Various avenues of outreach have been attempted. This pilot program is not unique in using a health museum as a point of outreach. However health museums have not been a major source of interventions, either. Little information was available regarding health museum visitor demographics, visitation patterns, companion status and museum trust levels prior to this pilot intervention. This visitor information will improve planning for further interventions and studies. ^ This thesis also examined prevalence data in a temporal context, the populations at risk for diabetes, the collecting agencies, and other relevant collected data. The prevalence of diabetes has been rapidly increasing. The increase is partially explained by refinement of the definition of diabetes as the etiology has become better understood. Increasing obesity and sedentary lifestyles have contributed to the increase, as well as the burdensome increase on minority populations. ^ Treatment options are complex and have had limited effectiveness. This would lead one to conclude that prevention and early diagnosis are preferable. However, the general public has insufficient awareness and education regarding diabetes symptoms and the serious risks and complications the disease can cause. Reaching high risk, high prevalence, populations is challenging for any intervention. During its “free family Thursdays” The Health Museum (Houston, Texas) has attracted a variety of ethnic patrons; similar to the Houston and Harris County demographics. This research project explored the effectiveness of a pilot diabetes educational intervention in a health museum setting where people chose to visit. ^

Sexualidad en el personal de Salud

La práctica de profesiones relacionadas con la salud se asocia a agotamiento físico y psicológico capaz de producir alteraciones en el plano de la sexualidad. Mediante una encuesta estructurada y anónima se valoró el grado de satisfacción respecto a la calidad de vida sexual y los factores relacionados con esta en médicos, residentes y enfermeros. El 62% afirmó que desde el inicio de la actividad laboral disminuyó la frecuencia y calidad de las relaciones sexuales, primordialmente en residentes (69.3%) (p<0.05) y mujeres (61%), el 33.1% refirió mayor atracción por otras personas y 15% infidelidad. El 71.8% consideró que la frecuencia no era óptima, el 48.6% no estaba satisfecho y el 37.3% que la pareja no estaba conforme con su desempeño sexual. Las mujeres utilizan más pretextos para evitar la relación sexual (22.6 vs. 6.1%), consideran que satisfacen menos a sus parejas (45 vs. 22%) y tienen orgasmos menos frecuentemente (22 vs. 8%) que los hombres (p< 0.05) y estos son más infieles (24.5 vs. 9.7%) (p< 0.05). Los residentes refieren que la frecuencia y calidad sexual disminuyó más con el inicio del trabajo (71.8 vs. 46.7%) (p<0.05), atribuido principalmente al cansancio extremo y se sienten más atraídos por compañeros de trabajo que los médicos de planta (24 vs. 2%) (p<0.05). El cuidado de la salud es un determinante de riesgo de disfunción sexual causado por las demandas y condiciones laborales, que genera un alto grado de estrés y desgaste psicofísico, que conducen a un deterioro de la salud sexual.

Conclusión: Se ha evidenciado que las esferas vaginales son eficaces en el tratamiento de mujeres con incontinencia urinaria de esfuerzo e igualmente efectivas, en el entrenamiento muscular del suelo pélvico.

Quality of life compared during pharmacological treatments and clinical monitoring for non-localized prostate cancer: a randomized controlled trial

To investigate the effects of different management strategies for non-localized prostate cancer on men's quality of life and cognitive functioning. Men with prostate cancer were randomly assigned to one of four treatment arms: leuprorelin, goserelin, cyproterone acetate (CPA), or close clinical monitoring. In a repeated-measures design, men were assessed before treatment (baseline) and after 6 and 12 months of treatment. A community comparison group of men of the same age with no prostate cancer participated for the same length of time. The men were recruited from public and private urology departments from university teaching hospitals. All those with prostate cancer who were eligible for hormonal therapy had no symptoms requiring immediate therapy. In all, 82 patients were randomized and 62 completed the 1-year study, and of the 20 community participants, 15 completed the study. The main outcome measures were obtained from questionnaires on emotional distress, existential satisfaction, physical function and symptoms, social and role function, subjective cognitive function, and sexual function, combined with standard neuropsychological tests of memory, attention, and executive functions. Sexual dysfunction increased for patients on androgen-suppressing therapies, and emotional distress increased in those assigned to CPA or close clinical monitoring. Compared with before treatment there was evidence of an adverse effect of leuprorelin, goserelin, and CPA on cognitive function. In deciding the timing of androgen suppression therapy for prostate cancer, consideration should be given to potential adverse effects on quality of life and cognitive function.

Candidaemia or Candidasis: Controversy of Staphylococcus Sexually Transmitted Infection?

Herbal medications are becoming increasingly popular but a most-extraordinary claim by traditional/herbal medical practitioners relates to a Gram-positive bacterium, Staphylococcus , which has been depicted as a deadly sexually transmitted disease that manifest in the form of worms and other symptoms; with contributory roles including infertility, sexual dysfunction and impotency. They further boasted that they are the only ones that possessed the remedy (herbal) for the Staphylococcus sexually transmitted scourge. In the absence of distinguishing phenotypic taxonomic tools, Staphylococcus and Candida spp. may be confused for each other. However, Staphylococcus is a bacterium and not an infection; therefore, there must be more to the traditional medical practitioners’ boasts in ability to cure an infection that was not an infection in the first place. In conclusion, the common sense is that candiaemia or candidiasis is most likely the misdiagnosed sexually transmitted Staphylococcus disease, which is of significant human clinical health issue.

The effects of acute administration of Chinese aphrodisiacs sold in Blantyre City on sperm characteristics and fertility profile in guinea pigs

Background Chinese aphrodisiacs have become popular remedy for sexual dysfunction and improvement of libido in men in Malawi. However, selling of these drugs seems not to be well regulated. Probably the aphrodisiacs that are currently on the market have unknown efficacy, potency and safety profiles. The aim of this study was to assess the efficacy of imported Chinese aphrodisiacs using guinea pigs as a model. Materials and Methods Two types of drugs were purchased from vendors in Blantyre City. Tonic tea, which was purported to improve erectile function and libido, and sperm multiplier tablets which were claimed to increase the sperm count. The tonic tea was prepared by soaking one tea bag in 100ml boiling water. The tea was cooled and administered to eight male experimental animals in varying doses. Each animal was introduced into a separate cage with a female guinea pig. Sexual behaviour such as mounting, sniffing behind the female were observed and recorded. Each sperm multiplier tablet was dissolved in distilled water and administered to the experimental animals in the morning and evening for seven days. At the end of the treatment, the experimental and control animals were sacrificed, their semen collected and analysed sperm motility, concentration and morphology. Results For the tonic tea, there were no statistical differences between the experimental and the control animals in terms of the number of mountings and sniffing behind the female. The sperm multiplier drug showed statistically significant differences between the experimental and the control animals in terms of the sperm motility (78.24 ± 1.35 vs. 86.54 ± 1.88, p< 0.05), and concentration (54.28 ± 1.24 vs. 67.59 ± 2.12, p<0.05). Conclusion The tonic tea did not show any efficacy in improving erection and libido. The sperm multiplier tablets, purported to increase sperm production, significantly increased the sperm motility, sperm concentration in the treated animals.

Miomatosis uterina, sintomatología urinaria y alteraciones sexuales en mujeres con indicación de tratamiento quirúrgico

Introducción Las pacientes con miomas uterinos pueden llegar a sufrir de síntomas urinarios y de disfunción sexual. Es para nosotros importante conocer la frecuencia de estas patologías en pacientes con miomas con indicación de cirugía atendidos en el Hospital Universitario Mayor Méderi y la relación entre estas tres entidades. Metodología Estudio cuasi experimental de antes-después. El estudio se encuentra dividido en dos fases, en esta primera fase a las pacientes se les aplicó los cuestionarios FSFI, IIQ-7 y UDI-6 antes de realizar el procedimiento quirúrgico. En una segunda fase se realizará un nuevo abordaje a los 6 y 12 meses donde se aplicarán los mismos instrumentos. Se utilizó coeficiente de Spearman y Kruskall-Wallis para evaluar la relación. Resultados En esta primera fase se incluyeron 81 participantes, con una mediana de años de 46 (RIQ=42-49) mínimo 33 y máximo 71 años. La mediana de miomas fue de 1 (RIQ1-2) máximo 5 miomas. El resultado total de la FSFI fue de 21(RIQ=18,5-25,5). La mediana de la escala UDI -6 fue de 50,4 (RIQ=0-31,2) y la mediana de IIQ-7 fue de 4,75 (RIQ=0-23,7). Se presentó una correlación negativa débil entre los puntajes de FSFI y los cuestionarios UDI-6 (-0.3604) e IIQ 7 (-0.3530), con una prevalencia de riesgo de disfunción sexual de 61%. Conclusiones En esta primera fase de la investigación se pudo observar una existencia de correlación entre la función sexual y la sintomatología urinaria. La prevalencia de disfunción sexual es mayor que en población de mujeres sin patología de miomas uterino.

Sexual desire, erectile dysfunction and the biomedicalization of sex in older heterosexual men

Aim To examine sexual desire in older age and the use of pharmaceuticals for sexual enhancement in the context of erectile dysfunction. Background The ability of the older person to fulfil sexual desire has not been well supported in Western society. Design The paper draws on themes that emerged during a phenomenological study of sexual desire in older age. Method Narratives were collected between 2008–2010 from in-depth interviews with six men and two women aged 65–84 years who were part of a larger Australian study of sexual desire in older age. Findings Emergent themes reveal that for some older people, the biomedicalization of sex can be a disappointing experience. Conclusion The findings illuminate the need for nurses who are at the front line of health care, health policy makers and educators, to consider sexual desire experienced in older age in the context of sexual health and healthy ageing. This study will contribute to a growing body of knowledge about sexual desire in older age

Psychological and interpersonal dimensions of sexual function and dysfunction.

To highlight the salient psychological and interpersonal issues contributing to sexual health and dysfunction; to offer a four-tiered paradigm for understanding the evolution and maintenance of sexual symptoms; and to offer recommendations for clinical management and research.

Integrating partners into erectile dysfunction treatment: improving the sexual experience for the couple

Introduction: Erectile dysfunction (ED) is a common condition estimated to affect more than 150 million men worldwide. ED should be regarded as a shared sexual problem which has significant detrimental effects both on the men who experience this condition and on their partners.
Evidence to support partner involvement in ED therapy: Evidence shows that the partner plays a key supportive role in the man's ED treatment and in successful long-term ED therapy. Including the partner in consultations may highlight discordant attitudes and communication problems between couple members which may indicate treatment acceptance or rejection, or realistic or unrealistic treatment expectations.
Options for partner involvement in ED therapy: Most patients with ED consult their physician in the absence of their partner. Therefore, involving the partner in therapy can be challenging. Two options which physicians should consider are: encouraging the patient to bring the partner into the office and, often more realistically, seeking information about, and providing information to, the partner, via the patient.
Objectives: The objective of these recommendations is to provide practical guidance on treating couples affected by ED, and suggest techniques that may be helpful in integrating the partner into the process of ED treatment.

Satisfaction with the treatment, confidence and 'naturalness' in engaging in sexual activity in men with psychogenic erectile dysfunction: preliminary results of a randomized controlled trial of three therapeutic approaches

OBJECTIVE To assess the efficacy of group psychotherapy (GTP) and/or sildenafil for psychogenic erectile dysfunction (ED). PATIENTS AND METHODS A randomized controlled single-blind trial was performed at the Institute of Psychiatry of the Medical School of at Universidade de Sao Paulo, Sao Paulo, Brazil. In all, 30 men with mild and moderate psychogenic ED were randomized to receive for 6 months: GPT plus 50 mg sildenafil on-demand, or 50 mg sildenafil on-demand exclusively, or GPT exclusively. Changes in score from baseline for three questions of the Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS) were evaluated at endpoint and after 3-months follow-up. RESULTS Satisfaction with the treatment, confidence and 'naturalness' increased in the GPT plus sildenafil and GPT exclusively groups (P = 0.001) from baseline to endpoint. The treatment-by-time comparison was not significant at endpoint vs the 3-month follow-up, in the three groups. There was no difference in the sildenafil group in the three study periods (P > 0.05) CONCLUSION Men with mild and moderate psychogenic ED had higher treatment satisfaction, confidence and naturalness in engaging in sexual activity when receiving GPT plus sildenafil or GP exclusively, when compared with sildenafil exclusively, as assessed by these three EDITS questions after 6-months treatment.

Does post-caesarean dyspareunia reflect sexual malfunction, pelvic floor and perineal dysfunction?

The aim was to define post-caesarean dyspareunia as a sexual and pelvic-perineal symptom. Post-caesarean (80 elective, 104 emergency) and 100 vaginally delivered primiparae had domiciliary interviews at 10 months postpartum. A total of 50 (28% and 27%) post-caesarean and 46 (46%) vaginally delivered, reported dyspareunia. Severely impaired general sexual health occurred in 82 (24% elective, 25% emergency, 35% vaginally delivered) as category 3 (dyspareunia with sexual symptoms) and 27 (10% elective, 7% emergency, 12% vaginally delivered) as category 4 (reduced frequency <6). The risk of dyspareunia (RR 1.14, CI 0.73, 1.77) or impaired general sexual health (RR 0.93, CI 0.32, 2.74) was similar among those with or without perineal trauma. Both caesarean and perineal scars were associated with sexual malfunction. Primiparae with new incontinence had a lower risk of dyspareunia than impaired general sexual health. Awareness of the associations of post-caesarean dyspareunia and impaired general sexual health with incontinence would facilitate appropriate obstetric decision-making.
