ObjectivesProstate cancer is a prevalent disease with a high impact on patients’ morbidity and mortality. Despite efforts to profile prostate cancer, the genetic alterations and biological processes that correlate with disease progression remain partially elusive. The purpose of this study is to review the recent evidence relating to the initiation and progression of prostate cancer in relation to the familial correlation of the disease, the genetic aberrations resulting in prostate cancer and the new molecular biology data regarding prostate cancer.Materials and MethodsA Medline database search identified all the existing publications on the molecular events associated with the pathogenesis and evolution of prostate cancer. Particular emphasis was given on the specific genetic phenomena associated with prostate cancer.ResultsLike other cancers, prostate cancer is caused by an accumulation of genetic alterations in a cell that drives it to malignant growth. Specific genes and gene alterations have been suggested to play a role in its development and progression. Aneuploidy, loss of heterozygosity, gene mutations, hypermethylation and inactivation of specific tumour suppressor genes such as GSTpi, APC, MDR1, GPX3 and others have been detected in prostate cancers, but generally only at a low or moderate frequency. The androgen receptor (AR) signalling pathway may play a crucial role in the early development of prostate cancer, as well as in the development of androgen-independent disease that fails to respond to hormone deprivation therapies. Other alterations linked to the transition to hormone-independence include amplification of MYC and increased expression of ERBB2 and BCL2. Inflammatory changes may also contribute to the development of prostate cancer.ConclusionThe identification of specific molecular markers for prostate cancer may lead to its earliest detection and better prediction of its behavior. The better understanding of the molecular events affecting prostate cancer progression may result in the introduction of new drugs to target these events thus providing a potential cure and a tool for prevention of this very common disease.

The care of patients suffering from advanced cancer is not limited in the hospital setting. It continues at home where the burden of care is borne by specific individuals. The aim of the present study was to survey and record the various problems faced by those who care for cancer patients at home. The study was conducted in our hospital during the summer of 2007. All participants completed, during a personal interview, a questionnaire which covered pathologic, social, psychological, spiritual/religious and financial problems. Seventy-six carers returned fully completed questionnaires. The most frequent problems reported were: anxiety regarding the patient's future (61.8%), troublesome symptoms such as pain (54%), increased economic burden-financial difficulty (51.3%), problems with patient's feeding (50%), unhappiness or depression (48,7%), emotional upset (47.4%), worsening of the patient's behaviour and personality (38.2%), difficulty of establishing a positive attitude regarding their current status (34.2%), transport to hospital (32.9%), assistance from the wider family circle (25%). Taking care of cancer patients at home creates several problems among carers. Many of them remain undetected. The acknowledgement and recognition of these problems by health-care professionals might contribute to finding solutions in order to assist the difficult task of these individuals.

OBJECTIVES To present our experience with immediate surgical treatment of penile fractures, using a midline ventral incision, as the choice of either immediate surgical or conservative treatment in penile fractures, as well as the type of surgical incision, remains controversial. PATIENTS AND METHODS In a period of 5 years (2002–2006) eight patients were treated in our department for a penile fracture. The diagnosis was established by a history and clinical examination. In six patients ultrasonography before surgery located the fracture in the right corpus cavernosum, distally from the penoscrotal junction. All patients had immediate surgery using a midline ventral incision and were followed for a mean of 1 year. RESULTS All patients presented with a penile haematoma, while five and two had concomitant scrotal and perineal haematomas, respectively. Penile urethral rupture was associated with corporal cavernosal rupture in one patient. In all patients a 5‐cm midline ventral incision was made at the penile raphe. There was unilateral rupture of the corpus cavernosum in seven patients and bilateral rupture with concomitant urethral rupture in one. The fascial defect was sutured in all patients and an end‐to‐end anastomosis made if there was urethral rupture. The early and late periods after surgery were uneventful. Erectile function was unaffected during the follow‐up. CONCLUSION Immediate intervention for penile fractures, using a midline ventral incision, achieves good early and late results. Our technique has the advantage of direct access to both corpora cavernosa and the anterior urethra, with a minimal skin incision.

In our study, participants preferred an initial approach of the donor by the recipient. The relief as a result of the recipient's improved health was suggested as a very strong motive for donation. Proper donor follow-up was considered to be paramount for the further development of LDKT.

Objectives: To prospectively evaluate the outcome of using a two-suture technique for the vesicourethral anastomosis (VUA) during radical retropubic prostatectomy (RRP). Materials and Methods: Two groups of 50 patients each underwent nerve-sparing RRP for localized prostate cancer by one surgeon. In one group, the vesicourethral anastomosis was performed using 2 Vicryl 2-0 stitches placed at the 3-and 9-o'clock positions and in the other group 6 Vicryl 2-0 stitches were placed at the 2-, 4-, 6-, 8-, 10-and 12-o'clock positions. The intraoperative and perioperative parameters analyzed were time to perform the VUA, time to remove the drain and hospitalization. The rate of incontinence, anastomotic stricture and erectile function were included in the outcome analysis. Results: The anastomotic time differed statistically between the 2 groups (mean 3.3 minutes for the 2-suture group and 10.5 minutes for the 6-suture group, p < 0.0001) with similar periods of drain removal (mean 3.12 days for the 2-suture group and 3.45 days for the 6-suture group; p = 0.13) and hospitalization (mean 4.66 days for the 2-suture group and 5.3 days for the 6-suture group; p = 0.09). The functional outcome was excellent for the 2-suture group with no patient suffering from incontinence or anastomotic strictures 1 year postoperatively, while in the 6-suture group there were 2 patients (4%) suffering from incontinence (2 underwent sling procedure) and 1 patient suffered from anastomotic stricture. Conclusion: The low number of sutures in the 2-suture VUA technique reduces operating times, does not influence perioperative and intraoperative parameters and results in excellent functional outcome.

Participants believed that LDKT is safe for the donor, and the pathway to surgery and post-operative follow-up should be performed in a way that ensures lack of coercion and includes family support and an extensive post-operative follow-up.

ARTICLE INFO ______________________________________________________________ ______________________Introduction: To investigate and highlight the effect of formaldehyde induced weight reduction in transurethral resection of prostate (TURP) and radical robotically-assisted prostatectomy (RALP) specimen as a result of standard chemical fixation. Materials and Methods: 51 patients were recruited from January 2013 to June 2013 who either underwent a TURP (n=26) or RALP (n=25). Data was collected prospectively by the operating surgeon who measured the native, unfixed histology specimen directly after operation. The specimens were fixed in 10% Formaldehyde Solution BP and sent to the pathology laboratory where after sufficient fixation period was re-weighed.Results: Overall mean age 64.78 years, TURP mean age 68.31 years RALP mean age 61.12years. We found that the overall prostatic specimen (n=51) weight loss after fixation was a mean of 11.20% (3.78 grams) (p≤0.0001). Subgroup analysis of the native TURP chips mean weight was 16.15 grams and formalin treated mean weight was 14.00 grams (p≤0.0001). Therefore, TURP chips had a mean of 13.32 % (2.15 grams) weight loss during chemical fixation. RALP subgroup unfixed specimen mean weight was 52.08 grams and formalin treated mean weight was 42.60 grams (p≤0.0001), a 19.32 % (9.48grams) mean weight reduction. Conclusion: It has not been known that prostatic chips and whole human radical prostatectomy specimen undergo a significant weight reduction. The practical significance of the accurate prostate weight in patient management may be limited, however, it is agreed that this should be recorded correctly, as data is potential interest for research purposes and vital for precise documentation.
