OBJECTIVE: To evaluate the effect of a gonadotropin-releasing hormone (GnRH) antagonist protocol using corifollitropin alfa in women undergoing assisted reproduction. METHODS: Six hundred and eighty-six in vitro fertilization-embryo transfer (IVF)/intracytoplasmic sperm injection (ICSI) cycles were analyzed. In 113 cycles, folliculogenesis was induced with corifollitropin alfa and recombinant follicle stimulating hormone (rFSH), and premature luteinizing hormone (LH) surges were prevented with a GnRH antagonist. In the control group (573 cycles), premature LH surges were prevented with GnRH agonist injection from the midluteal phase of the preceding cycle, and ovarian stimulation was started with rFSH. The treatment duration, quality of oocytes and embryos, number of embryo transfer (ET) cancelled cycles, risk of ovarian hyperstimulation syndrome (OHSS), and the chemical pregnancy rate were evaluated in the two ovarian stimulation protocols. RESULTS: There were no significant differences in age and infertility factors between treatment groups. The treatment duration was shorter in the corifollitropin alfa group than in the control group. Although not statistically significant, the mean numbers of matured (86.8% vs. 85.1%) and fertilized oocytes (84.2% vs. 83.1%), good embryos (62.4% vs. 60.3%), and chemical pregnancy rates (47.2% vs. 46.8%) were slightly higher in the corifollitropin alfa group than in the control group. In contrast, rates of ET cancelled cycles and the OHSS risk were slightly lower in the corifollitropin alfa group (6.2% and 2.7%) than in the control group (8.2% and 3.5%), although these differences were also not statistically significant. CONCLUSION: Although no significant differences were observed, the use of corifollitropin alfa seems to offer some advantages to patients because of its short treatment duration, safety, lower ET cancellation rate and reduced risk of OHSS.

BACKGROUND: Naringin, one of the flavonoids in citrus fruit peels, is known to have antioxidant and hepatotonic effects in animal studies. We evaluated the effect of naringin on 1) blood lipid profiles, 2) regression of fatty streak of aorta, and 3) liver toxicity in diet-induced hypercholesterolemic rabbits. METHODS: New Zealand White Rabbits (2.0 - 2.5 Kg) were divided to three groups; group without treatment, group treated with 100 mg/kg/d or 500 mg/kg/d naringin, and group treated with 1 mg/kg/d or 20 mg/kg/d lovastatin. They were fed on 0.25% or 1.0% cholesterol-containing diet for 8 weeks and then sacrificed. Blood samples were collected for measurement of total cholesterol, HDL-cholesterol, triglyceride, serum GOT and GPT. Aortas and livers were harvested for evaluation of fatty streak and pathologic examination. RESULTS: 1)Feeding of 1% cholesterol diet for eight weeks significantly increased the cholesterol level upto 20 folds. Neither lovastatin nor naringin did lower these marked hypercholesterolemia. But both naringin (500 mg/kg/d) and lovastatin (1 mg/kg/d) significantly reduced the area of fatty streak by 75% and 58%, respectively. Naringin was more effective in inhibition of fat infiltration into liver than lovastatin which showed hepatotoxicity as increase of serum GPT level (p=0.01). 2)Feeding of 0.25% cholesterol diet for eight weeks significantly increased the cholesterol level upto 17 folds. Total cholesterol and triglyceride levels tended to decrease by treatment with naringin (500 mg/kg/d) and lovastatin (20 mg/kg/d), but this decreases were not statistically significant. However, areas of fatty streak significantly decreased by treatment with naringin and lovastatin by 64 and 82%, respectively (p<0.05). Microscopic analysis revealed that foam cell infiltration into intima was significantly reduced by naringin and lovastatin. In contrast to lovastatin, naringin significantly reduced the level of serum GPT (p<0.05). CONCLUSION: Like lovastatin, naringin has strong antiatherogenic action which may not be associated with its very mild lipid lowering action. In contrast to lovastatin, naringin does have hepatoprotective effect.

PURPOSE: Current evidence indicates that ultrasonography of the breast is an important adjunct to mammography and clinical examination in the diagnosis of palpable breast abnormalities. An assessment of the value of office-based ultrasonography of a palpable breast mass performed by a breast surgeon was the aim of this work. METHODS: A 7.5 MHz linear probe was used to perform office-based ultrasonography in 109 consecutive female patients having a palpable solid breast mass between August 1998 and December 1999. Breast masses diagnosed histologically as fibroadenomas or breast cancer were included in this study. The clinical impression from the physical examination (PE), the result of officed-based ultrasonography done by a surgeon (OUSG), and comprehensive judgement engaging both PE and OUSG (PEUSG) were recorded in each patient's hospital record as benign or malignant at the first visit. The diagnostic values of PE, OUSG, PEUSG, mammography (MMG), and ultrasonography done by a radiologist (USG) were compared. RESULTS: Of 109 masses, a fibroadenoma was diagnosed in 73 patients while a carcinoma was established in 36 patients. The sensitivity, the specificity, the accuracy rate, and the kappa coefficient were 91.7%, 89.0%, 89.9%, and 0.780 for PE; 100%, 90.4%, 93.6%, and 0.862 for OUSG; 97.2%, 97.3%, 97.2%, and 0.938 for PEUSG; 90.4%, 89.4%, 90%, and 0.630 for MMG; and 88.9%, 90.9%, 90% and 0.798 for USG. The diagnostic accuracy of PEUSG was significantly higher than those of PE and MG (p<0.05). CONCLUSION: These data suggest that office-based ultrasonography of the breast performed by a surgeon is a useful adjunct to clinical evaluation of the breast mass and permits timely and cost-effective patient care.

PURPOSE: Gastric emptying after a gastric resection has been studied in early gastric cancer. Most reports are retrospective and show that gastric emptying after gastroduodenal reconstruction is faster than normal. This study was designed to evaluate the gastric-emptying pattern after a gastroduodenal reconstruction with preservation of the truncal vagus nerve had been performed on a patient whose preoperative gastric-emptying time had been normal. METHODS: From July 1996 to February 1998, we performed a distal gastrectomy with gastroduodenal reconstruction with preservation of the truncal vagus nerve in 11 patients (9 patients with early gastric cancer, 1 patient with advanced gastric cancer, and 1 patient with high-grade dysplasia) whose preoperative gastric-emptying times was normal. To evaluate the gastric emptying after the gastrectomy and gastroduodenal reconstruction, we analyzed the lag time (when 10% of food is delivered to the duodenum), T1/2 (when 50% of food is delivered to the duodenum), and the residual food in the stomach after 100 minutes (%) by means of radionuclide scintigraphy using a single-head gamma camera after ingestion of an 99mTc-tin-colloid steamed egg. We defined the delayed gastric emptying as T1/2 longer than the mean of the preoperative value by 2 standard deviation. RESULTS: Among the 11 patients with gastroduodenal reconstruction, gastric emptying was normal in 4 patients and delayed in 7 patients; only one of the delayed cases has GI symptoms such as early satiety. There were no rapid gastric emptying cases. CONCLUSION: Rapid gastric emptying after gastroduodenal recon struction with preservation of the truncal vagus nerve was rare.

PURPOSE: To evaluate the clinical outcome, patient's satisfaction and complications of inside-out tension-free transobturator suburethral tape (inside-out TVT-O) procedure for the surgical treatment of female stress urinary incontinence during the follow-up 2 years. MATERIALS AND METHODS: From August 2004 to August 2006, 86 women with stress urinary incontinence underwent inside-out TVT-O procedures. We analyzed parameters incuding history taking, physical examination and urodynamic study. Postoperative clinical outcome, patient's satisfaction, complications and success rates for Stamey grade were evaluated after 12 months and 24 months. RESULTS: The success rates were 97.6% (cured 90.7%, improved 6.9%) and 97.6% (cured 88%, improved 9.6%) at 1 and 2 years follow-up. The satisfaction rates were 95.2% at 1 year and 91.6% at 2 years. There was no significant difference of success rate between pure stress urinary incontinence and mixed urinary incontinence (p>0.05). There were no serious or long-term complications related to the procedure. CONCLUSIONS: We considered that inside-out TVT-O procedure was a safe and effective procedure for female stress urinary incontinence for 2 years, although longer follow-up is necessary to determine long-term effect.
