Oncoplastic breast reduction using the short scar periareolar inferior pedicle reduction technique

After a partial mastectomy, large or ptotic breasts can be reconstructed using breast reduction techniques. Wise-pattern reduction is typically used to remove masses in any quadrant of the breast, but this technique leaves a large inverted T-shaped scar. Instead, the short scar periareolar inferior pedicle reduction (SPAIR) technique involves a periareolar line and does not result in a scar along the inframammary fold (IMF). A 49-year-old patient with macromastia and severely ptotic breasts was diagnosed with invasive cancer of the left breast. Her large breasts caused pain in her back, shoulders, and neck. She also expressed concern about postsurgical scarring along the IMF. In light of this concern, we chose the SPAIR technique, and we designed and performed the procedure as described by Hammond. During surgery, we removed 36 g of breast tumor and 380 g of breast parenchyma from the left breast. To establish symmetry, we also removed 410 g of tissue from the right breast. Postoperatively, the patient reported satisfaction regarding the reduction mammaplasty and, in particular, noted decreased back, shoulder, and neck pain. In summary, we used the SPAIR technique to achieve oncologic and aesthetic success in a patient with macromastia and a tumor located lateral to the nipple-areolar complex.

The Change of Prostate-specific Antigen and Prostate-specific Antigen Density in Patients with Benign Prostatic Hyperplasia after Dutasteride Treatment / 대한비뇨기과학회지

PURPOSE: Dihydrotestosterone(DHT) is key to the initiation and maintenance of abnormal prostatic growth in benign prostatic hyperplasia (BPH). Five alpha-reductase inhibitor reduces prostatic growth and serum prostate-specific antigen(PSA) by blocking the conversion of testosterone to DHT. Dutasteride is a dual(type 1 and 2) 5alpha-reductase inhibitor. We evaluated the effects of dutasteride on prostate volume, PSA, and PSA density in men with BPH. MATERIALS AND METHODS: A total of 83 men with a clinical diagnosis of BPH were treated with dutasteride and an alpha-blocker. We investigated the change in prostate volume, PSA, and PSA density 6 and 12 months after initiation of dutasteride therapy. RESULTS: After 6 months of dutasteride therapy, the total prostate volume was reduced from baseline by a mean of 15.46%, the PSA was reduced by a mean of 48.24%, and the PSA density was reduced by a mean of 37.97%(p<0.001). After 12 months of dutasteride therapy, the total prostate volume was reduced from baseline by a mean of 23.3%, the PSA was reduced by a mean of 52.57%, and the PSA density was reduced by a mean of 36.2%(p<0.001). There were no differences in the regression rate of PSA and PSA density, in contrast to prostate volume, between 6 and 12 months of dutasteride therapy by repeated measures ANOVA. CONCLUSIONS: The findings in this study demonstrate that the actual PSA in men receiving dutasteride would be multiplied by 2 considering the PSA regression rate after 12 months.

The Prevalence and Risk Factors of Nocturia for Males Participating in a Prostate Examination Survey / 대한비뇨기과학회지

PURPOSE: Elderly men are often troubled by lower urinary tract symptoms (LUTS), including frequency, urgency, incontinence and nocturia. Especially, nocturia is one of the frequently complained about urologic symptoms and this can be combined with sleep disorders. We investigated the prevalence and risk factors for nocturia in males who participated in a prostate examination survey. MATERIALS AND METHODS: A total of 7,299 men participated in a prostate examination survey from March 2003 to December 2006; these men were given an International Prostate Symptom Score(IPSS) and they underwent transrectal ultrasonography of the prostate. The prevalence of nocturia and its associated factors, which included age, the IPSS severity, the prostate volume and the place of residence, were evaluated. RESULTS: Among the men who were evaluated, 23.4% reported voiding once per night and 68% reported voiding twice or more per night. The severe IPSS group revealed a significantly higher nocturia score compared to the mild and moderate IPSS group. While the nocturia score and the other LUTS score increased significantly with age, only the nocturia score increased significantly with age in each of the IPSS severity groups. The nocturia score increased significantly with a prostate volume >or=30g. Men living in Seoul showed a significantly lower nocturia score than that for men living in other areas. Multiple logistic regression analysis also indicated that an older age, a severe IPSS score, the country of residence were the independent risk factors. Multiple regression analysis revealed the nocturia score to have the highest correlation with the quality of life. CONCLUSIONS: For Korean males, the prevalence of nocturia >or=2 is 68% and the incidence of nocturia increased significantly according to age, the IPSS severity, the prostate volume and the place of residence.

Pelvic Schwannoma Causing Recurrent Acute Urinary Retention / 대한비뇨기과학회지

Schwannoma is a tumor that arises from neural sheath Schwann cells of peripheral nerves. Schwannoma is mostly solitary, except when it occurs in association with Von Recklinghausen's disease. Solitary schwannoma can occur in association with a nerve anywhere within the body, but rarely occurs in the pelvis. Microscopically, the tumors can be divided into hypercellular bundles of spindle-shaped cells (Antoni A area) and areas of lower cellularity, with loose myxomatous arrangement of cells and fibers (Antoni B area). Complete resection of pelvic schwannoma is a curative treatment. We report a case of benign presacral cystic schwannoma that caused recurrent acute urinary retention in a 79-year-old woman, along with a review of the literature.
