Patients with genital HPV lesion, as well as partners, usually present higher psychological stress, than the actual medical consequences of the lesion. Follow-up of these patients should be based on education and counseling. HPV molecular tests are not recommended as a follow-up test, or for screening partners. Development and implementation of protocols, by the centers or units, that follow these patients, are recommended.

The treatment of condyloma is generally a challenge in clinical practice. Although the spontaneous resolution rate is high, a significant proportion of patients seek treatment, not because of symptomatology, but mainly for aesthetic issues and concerns related to the transmission or worsening of existing lesions. The available treatments should be applied only for clinically evident macroscopic lesions. Ideally, available therapies should have rapid action onset and clearance, resolve symptoms, reduce recurrence rate and viral load, be effective in treating small lesions, and be well tolerated. However, none of the currently available treatments is clearly more effective than the others and there is no ideal treatment for all patients or for all condyloma. Therefore, the therapeutic decision should be based on the clinician's experience, available resources, lesion morphology, size, number and location, primary or recurrent lesions, disease severity, patient preference and expectations, patient's immune competence, convenience, tolerance, cost of treatment and results of previous therapies. The available treatments are divided into three groups: applied by the patient himself (imiquimod 3.75 or 5%, podophyllotoxin .5%, synecatekines 10% or 15%), applied by the health care provider (bi- and tricloacetic acids 80%-90%, intralesional interferon alpha, cryotherapy, surgical removal, electrofulguration, laser ablation) and experimental or alternative therapies (topical cidofovir, intralesional bleomycin, photodynamic therapy). Treatment methodologies can be further divided into their action - ablative or destructive treatment (cryotherapy, electrofulguration, laser ablation, surgical excision), cytotoxic or proapoptotic treatments (podophyllotoxin .5%, 5-fluoruracil, bleomycin) and immunomodulatory treatments (imiquimod 3.75% or 5%, synecatekines 10% or 15%, intralesional interferon alpha). The overall success rate of the various treatments available ranges from 23% to 94%. Only treatments that include cryotherapy or surgical excision are suitable in condyloma with any anatomical location and that have the highest success rate in monotherapy. Recurrences are common regardless of the treatment received. In contrast, immunomodulatory therapies despite having lower initial clearance rates appear to have higher probabilities of cure in the medium term, with low recurrence rates. Some treatments may be combined with each other and the effectiveness of combined therapies appears to be superior to monotherapy (proactive sequential treatment). The consensuses for the treatment of HPV also consider special situations: immunocompromised patients, meatus and intraurethral lesions and treatment of the partner.

[Recommendations in Male HPV from the Portuguese Society of Andrology, Sexual Medicine and Reproduction: Prevention]. / Recomendações em HPV Masculino da Sociedade Portuguesa de Andrologia, Medicina Sexual e Reprodução: Prevenção.

The prevention of HPV-related diseases is an important healthcare issue due to its increasing incidence. Primary prevention is most important in males as it avoids initial infection and includes the use of condom, circumcision and vaccination. Primary prevention with vaccination is effective in decreasing HPV-related lesions in women up to 45 years old and the existing data for men comes from the experience from vaccinating women. Although it is the only vaccine that prevents cancer, the worldwide rates of vaccination in males is very low due to lack of information related to efficacy and side effects, lack of recommendation from the treating doctor, price and concern about encouragement of sexual promiscuity.

[The consensus of the Portuguese Society of Andrology, Sexual Medicine and Reproduction on Male HPV: diagnosis]. / Consensos em HPV masculino da Sociedade Portuguesa de Andrologia, Medicina Sexual e Reprodução: diagnóstico.

HPV infection affects about 50% of sexually active individuals at least once in a lifetime. Diagnosis is made on careful inspection of the genital area and can be divided into benign lesions (genital warts or condyloma acuminatum) and pre-malignant lesions (intraepithelial neoplasia) that can lead to cancer (invasive neoplasia). Diagnostic recommendations are reviewed in Male, Female, Couple and in the immunocompromised host. Recent histological concepts are also discussed.

Biological principles and clinical application of positron emission tomography-tracers in prostate cancer: a review.

Prostate carcinoma is the most common malignancy in men and the second cause of death by cancer in the western world. Currently, prostate carcinoma's diagnosis is achieved by transrectal ultrasound-guided biopsy (gold-standard), usually requested after an elevation of prostate specific antigen (PSA) levels or an abnormal digital rectal exam or transrectal ultrasound. Nevertheless, this diagnosis sequence sometimes presents with significant limitations. Therefore, there is a need of a diagnosis modality that improves the tumor detection rates and that offers information for its accurate staging, allowing the treatment's planning and administration. Molecular imaging by the means of positron emission tomography uses radiopharmaceuticals labeled with positron-emitting radioisotopes to detect metabolic changes that might be suggestive of cancer tissue. Recently, this technique has suffered a huge dynamic development, and researchers have been working on novel radiotracers agents to improve accuracy in targeting and detecting prostate tumors. On this review, it is highlighted that the most promising positron emission tomography-tracers that will, in a near future, not only improve diagnostic abilities for prostate carcinoma but also open new possibilities for theranostic approaches to treat this malignancy at a world level.

Local Treatment of Metastatic Prostate Cancer: What is the Evidence So Far?

BACKGROUND: Advances in technological, laboratorial, and imaging studies and new treatments available in the last decades significantly improved prostate cancer survival rates. However, this did not occur in metastatic prostate cancer (mPCa) at diagnosis which, in young and fit patients, will become invariably resistant to the established treatments. Progression will lead to an impairment in patients' quality of life and disease-related death. METHODS: The authors intend to perform a literature review of the advantages of primary treatment of mPCa. Articles were retrieved and filtered for relevance from PubMed, SciELO, and ScienceDirect until March 2017. RESULTS: Primary treatment is currently indicated only in cases of nonmetastatic PCa. Nonetheless, there might be some benefits in doing local treatment in mPCa in order to control local disease, prevent new metastasis, and improve the efficacy of chemotherapy and hormonotherapy with similar complications rate when compared to locally confined cancer. Independent factors that have a negative influence are age above 70 years, cT4 stage or high-grade disease, PSA ≥ 20 ng/ml, and pelvic lymphadenopathies. The presence of 3 or more of these factors conditions CSS and OS is the same between patients who performed local treatment and those who did not. Metastasis degree and location number can also influence outcome. Meanwhile, patients with visceral metastases have worse results. CONCLUSIONS: There is growing evidence supporting local treatment in cases of metastatic prostate cancer at diagnosis in the context of a multimodal approach. However, it should be kept in mind that most of the existing studies are retrospective and it would be important to make consistent prospective studies with well-defined patient selection criteria in order to sustain the existing data and understand the main indications to select patients and perform primary treatment in mPCa.

New Therapeutic Perspectives in Premature Ejaculation.

OBJECTIVE: To review potential therapeutic targets and future therapeutic molecules in premature ejaculation (PE). PE is the most prevalent sexual dysfunction and affects about 23% of the male population. It is a universal disorder: it is independent of age and social or marital status. Men with PE typically refer associated comorbidities and report a significant impact not only on their quality of life but also on the satisfaction of the partner. Although common and treatable in most cases, the drugs currently available may affect sexual spontaneity and the cost can prove to be a hindrance. MATERIALS AND METHODS: A comprehensive literature revision was performed using PubMed and Scopus to identify relevant articles published in the fields of PE and its treatment until May 2015. RESULTS: The main central targets identified include serotonergic, dopaminergic, and oxytocinergic neurotransmitters, opioid receptors, and mechanisms involved in the control of the spinal ejaculatory generator, located at the T12-L1-2 spinal cord level. On the other hand, peripheral interventions at semen's transport may also delay ejaculation by decreasing sequential contractions of the epididymis, vas deferens, seminal vesicles, prostate, and bladder neck. CONCLUSION: There is a wide range of future options with regard to the treatment of PE. Molecules like DA-8031, Promescent, silodosin, Botulinum toxin-A, and resiniferatoxin may be near future treatments for this disorder.
