{"title":"Finasteride following balloon dilatation of the prostate.

After a 4-week placebo runin period, 64 patients with successful dilatation and over 50 % reduction in symptoms were randomized to receive either finasteride (33 pts.) at 5 mg/day or placebo (31 pts.) for 24 months. Altogether 12 patients dropped out at some stage, and the final analysis hence included 27 patients in the finasteride group and 25 patients in the placebo group.</p><p><strong>Results: </strong>The symptom scores increased by an average of 3.2 points in the finasteride group and 4.4 points in the placebo group during two years. The mean maximum flow in the finasteride group remained constant: 13.7 ml/s at baseline and 13.9 ml/s at 24 months. In the placebo group the mean maximum flow decreased from 13.3 ml/sec to 11.2 ml/s. During the two-year study period, neither of the groups displayed any changes in residual urine. The above mentioned changes were not statistically significant, however. Prostate volume and serum PSA were significantly lower in the finasteride group (p < 0.001). The groups did not differ with regard to side-effects.</p><p><strong>Conclusions: </strong>On the basis of the findings, BPH patients with moderate to severe symptoms can be treated with balloon dilatation. The effect of balloon dilatation is quick, and it alleviates the patients' symptoms immediately. Finasteride treatment maintains the positive effect of balloon dilatation. This combination of treatment is tolerated well and side-effects are rare. The favourable effect of balloon dilatation was maintained for at least two years. Finasteride treatment diminished significantly both prostate volume and serum prostate-specific antigen after balloon dilatation compared to placebo treatment.</p>","PeriodicalId":75495,"journal":{"name":"Annales chirurgiae et gynaecologiae","volume":"88 4","pages":"299-303"},"PeriodicalIF":0.0,"publicationDate":"1999-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21516788","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We have succeeded to construct the in vitro cultured bone on the porous framework of hydroxyapatite ceramics (HA). After 2 weeks of the culture, the construct showed the existence of mineralized collagen fibers on the surface of HA determined by Scanning Electron Microscopy. The construct also demonstrated high alkaline phosphatase (ALP) activity together with noticeable level of osteocalcin. The results indicate that the construct consisted of thin layer of bone matrix covered hydroxyapatite surface and abundant bone forming active osteoblasts. After the in vivo implantation of the construct, volume of the matrix increased and obvious bone tissue was detected by ordinal microscopy even one-week after implantation and its high osteogenic activity was maintained for a long term (one year). The in vivo bone is biologically active tissue evidenced by Northern blot analysis of the implanted construct which showed ALP and osteocalcin mRNA expression comparable to those of normal cancellous bone. These results demonstrate that the in vitro fabricated cultured bone/HA construct can possess new bone forming capability in in vivo situations. We have also succeeded to fabricate the construct using aged human marrow cells and the construct showed thick lamellar bone formation after the in vivo implantation. Based on these findings, we propose alternative approach for bone reconstruction surgery using the autogenous cultured bone/HA construct. Importantly, we can fabricate the implantable autogenous bone tissue derived from patient's marrow cells and the cells can be obtained by needle aspiration without damaging the patient's normal tissue.</p>","PeriodicalId":75495,"journal":{"name":"Annales chirurgiae et gynaecologiae","volume":"88 3","pages":"186-92"},"PeriodicalIF":0.0,"publicationDate":"1999-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"21395085","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
