This paper reviews hypertrophic osteopathy and describes one case report. Hypertrophic osteopathy is a rare pathologic disease process and is observed secondary to a mass in the thorax. In response to the presence of a mass(es), nonoedematous soft tissue swellings and a diffuse periosteal new bone formation develop in all four limbs. The result is mild to severe lameness. A twelve-year-old sexually intact female Cocker spaniel had undergone radical mastectomy on both sides in another veterinary hospital about two years before presentation in our hospital with lameness of both hind limbs. Pain and soft tissue swelling on the distal parts of extremities were determined in clinical examinations. Radiographs revealed periosteal new bone formation on all the long bones of all four limbs, pelvis and sternum; additionally, intrathoracic masses were observed. Euthanasia was performed five months later. Macroscopic examinations of the lungs revealed diffuse and exuberant masses with grizzled whitish cross-sectional colour and with necrotic and haemorrhagic foci. The radius-ulna, tibia, metacarpal and metatarsal bones of both limbs were examined and collected after the necropsy examination. Bone specimens were thicker and the outer surfaces seemed to be rough. At the histopathologic examination of the lung tissue, ovoid or round shaped and hyperchromatic nucleated diffuse anaplastic mammary gland epithelial cells were observed. According to these findings, these masses were diagnosed as the metastasis of malignant mixed tumours.

We investigated the effect of prostatic inflammation on prostate-specific antigen (PSA) and per cent-free PSA levels changing after antibacterial therapy. We evaluated 48 patients whose PSA levels were between 4 and 10 ng/ml, without any suspicious findings on digital rectal examination, with no infection findings in urine analysis. Prostatic inflammation was assessed with prostatic massage. All the patients were given antibiotic therapy for 3 weeks. Patients were re-evaluated 3 weeks after antibacterial therapy with PSA (free/total) and urinalysis. Ten core biopsies were taken with transrectal ultrasound. No differences were found in terms of age, pre-and post-treatment PSA, and PSA varying between patients with and without inflammation in the prostatic massage. In 18 patients, PSA decreased below 4 ng/ml. Prostate cancer was found in 10.8% of the patients with PSA between 4 and 10 ng/ml and none of the patients with PSA values below 4 ng/ml. We suggest an antibiotic therapy for 3 weeks without regarding inflammation findings when PSA is in the gray zone, for biopsy decision.

Aim The association of 5-alpha reductase inhibitor (5ARI) therapy and sexual dysfunction has been reported. Some patients claim persistent erectile dysfunction despite long-term discontinuation of 5ARI treatment. The aim of this study was to assess erectile function after cessation of 5ARI therapy using a rat model. Methods Twenty-six adult male Sprague-Dawley rats were randomized into three groups: (i) control (N = 10); (ii) 8-week dutasteride treatment (0.5 mg/rat/day, in drinking water, N = 8); and (iii) 6-week dutasteride treatment followed by a 2-week washout period (N = 8). The experiments were performed after 8 weeks from the initiation of treatment in all groups. In vivo erectile activity and in vitro contractile and relaxant responses of cavernosal smooth muscle were investigated. Results In vivo erectile activity (intracavernosal pressure [ICP]/mean arterial pressure [MAP] and total ICP) in treatment groups were significantly decreased compared with controls (ICP/MAP: P < 0.001 for 2.5 v, 5 v, and 7.5 v; total ICP: P < 0.001 for 5 v and P < 0.01 for 7.5 v). Acetylcholine-induced relaxations were diminished in treatment groups (P < 0.05). Relaxant responses to electrical field stimulation (EFS) were decreased in the 8-week treatment group (P < 0.05) but were similar to controls in the washout group. Sodium nitroprusside (SNP)-induced endothelium-independent relaxations were reduced in the 8-week dutasteride treatment group (P < 0.01), while these responses were restored in the washout group. The contractile responses to the alpha1-adrenergic agonist phenylephrine were decreased in treatment groups compared with controls (P < 0.01). Direct neurogenic contractile responses in the dutasteride groups were significantly lower than controls between 1 and 15 Hz frequencies (but not at 20 Hz) and washout partially restored the responses at 10 and 15 Hz. Conclusion Discontinuation of dutasteride improved the relaxant responses to EFS and SNP, while cholinergic and adrenergic responses remained depressed. Our findings suggest a time-dependent detriment of dutasteride on erectile function. The withdrawal/washout effect of 5ARIs on parameters of human sexual function warrants further investigation.

We aimed to evaluate the effect of acetylsalicylic acid (ASA) treatment on diabetes-induced erectile dysfunction. Adult male Sprague-Dawley rats were divided into four groups as follows: (i) control (C), (ii) diabetic (D), (iii) ASA-treated control (C+ASA) and (iv) ASA-treated diabetic (D+ASA) groups. In groups 2 and 4, diabetes was induced by injection of 35 mg kg(-1) streptozotocin. ASA (100 mg kg(-1) day(-1) , orally) was administrated to rats in groups 3 and 4 for 8 weeks. Both intracavernosal pressure (ICP) and mean arterial blood pressure (MAP) were measured in in vivo studies. In organ bath, the relaxation responses to acetylcholine (ACh), electrical field stimulation (EFS) and sodium nitroprusside were tested in corpus cavernosum (CC) strips. The mRNA expression for neuronal nitric oxide synthase (nNOS) was calculated using reverse transcription polymerase chain reaction technique. In in vivo experiments, diabetic rats displayed reduced ICP/MAP values, which were normalised with ASA treatment. The relaxant response to high-dose ACh and EFS at low frequencies (1-8 Hz) in CC strips from the D+ASA group were significantly higher when compared to the D group. Treatment with ASA normalised the raised mRNA expressions of nNOS in diabetic penile tissues. ASA may be involved in mRNA of protein synthesis of NO released from nonadrenergic and noncholinergic cavernosal nerve in diabetes.
