Differences in the risk factors for clinical benign prostatic hyperplasia between the Mongolian and the Han people / 中华男科学杂志

<p><b>OBJECTIVE</b>To define the differences in the risk factors for clinical benign prostatic hyperplasia (BPH) between the Mongolian and the Han people.</p><p><b>METHODS</b>Between January 2003 and June 2005, 63 Mongolian and 63 Han patients with BPH were interviewed using a questionnaire consisting of the risk factors for BPH.</p><p><b>RESULTS</b>The intake of alcohol and dairy products was higher in the Mongolians than in the Hans (P <0.05). The consumption of milk tea, dairy products and meat was significantly greater in the Mongolians ( >250 g per day) than in the Hans (P <0.01). And there were more smokers (the smoking index >300) with moderate to severe symptoms (IPSS > 7) in the Mongolians than in the Hans (85.71% vs 57. 14%, P <0.01). The incidence of intraprostatic chronic inflammation and calcification within the prostate gland was higher in the Mongolians (28% vs 11% , P < 0.05; 36.5% vs 15.87% , P < 0.01, respectively). No significant difference was observed between the two groups in body mass, blood pressure, marriage age, offspring number, physical activity, IPSS score and PSA level.</p><p><b>CONCLUSION</b>Compared with Han BPH patients, the Mongolian BPH patients had greater alcohol intake, higher protein diet and higher incidence of intraprostatic chronic inflammation, and those with the smoking index greater than 300 were more likely to receive surgical treatment.</p>

Testicular tumor in Mongolian men (report of 35 cases) / 中华男科学杂志

<p><b>OBJECTIVE</b>To improve the diagnosis, therapy and prognosis of testicular tumor in Mongolian men.</p><p><b>METHODS</b>A retrospective review of 35 cases of testicular tumors in Mongolian men from seven medical centers dated from 1990 to 2004 was performed.</p><p><b>RESULTS</b>The usual presentation of a testicular tumor was a nodular or painless swelling of one gonad. The mean delay in diagnosis was 40.03 +/- 53.45 weeks. For 16 patients, delay in diagnosis was more than or equal to six months. The histologic composition of this series was 21 (60%) seminoma, 10 (28.6%) nonseminoma, 2 (5.7%) lymphoma, 1 (2.35%) fibroneuroma and 1 (2.35%) leiomyoma. Regarding stage, 22, 2, and 5 of 29 germ cell tumors were seen initially as stage I, II, and III, respectively. Combined therapy, including radical orchiectomy, radiotherapy and chemotherapy, were taken. 29 cases have been followed for 2 months to 10 years, 4 out of them died of distant metastasis, one died of other disease, one lives with tumor, the others live without relapse and metastasis. Three and 5-year survival rates for Mongolian patients with seminoma and nonseminoma were 95.0%, 95.0%, 57.1% and 42.8%, respectively.</p><p><b>CONCLUSION</b>In this article, the rate of seminoma to germ cell tumors is higher than that of general population. There is an increased mean delay in diagnosis for Mongolian patients. Three and 5-year survival rates for nonseminoma are lower than that for seminoma. Better public awareness regarding testicular tumor in this population, advances in diagnosis and therapy will help to improve therapeutic effectiveness and prognosis.</p>
