A 16-year old male patient visited the hospital complaining of inguinal pain and internal snapping of right hip joint. In physical examination, the patient was presumed to be diagnosed femoroacetabular impingement (FAI) and acetabular labral tear. In radiologic evaluation, FAI and acetabular labral tear were identified and bony tumor associated with internal snapping was found on the posteromedial portion of the femoral neck. Despite of conservative treatment, there was no symptomatic improvement. So arthroscopic labral repair, osteoplasty and resection of bony tumor were performed. The tumor was pathologically diagnosed as osteochondroma through biopsy and all symptoms improved after surgery. There was no recurrence, complication or abnormal finding during 1 year follow up. Osteochondroma located at posteromedial portion of femoral neck can be a cause of internal snapping hip and although technical demands are challenging, arthroscopic resection can be a good treatment option.

BACKGROUND: The inhibitory effects of nitric oxide(NO) on platelet adhesion and vascular smooth muscle cell(VSMC) proliferation may have a possible role inhibiting development of neointima following balloon catheter induced injury. We tested the hypothesis that L-arginine, the precursor of NO, would attenuate neointima formation following balloon catheter induced injury via regulation of antagonistic balance between proliferation and apoptosis of VSMC. METHODS: Adult, male Sprague-Dawley rats(300 to 400g) were anesthetized with ketamine (100mg/kg intraperitoneally). The left common and external carotid artery were exposed. For endothelial denudation, 2mm angioplasty catheter was introduced through the left external carotid artery into the left common carotid artery. The catheter was inflated at I atm. and withdrawn three times. Animals were randomized to receive 2.25% L-arginine in their drinking water(n=14) or placebo(n=16) from 2 days prior to and 9 days following denudation. VSMC proliferation was quantified by immunohistochemical staining with an antibody to the proliferating cell nuclear antigen(PCNA). The cells undergoing apoptosis were identified by terminal nucleotidyl transferase-mediated nick end labeling(TUNEL) method and morphologic changes by computerized planimetry and transmission electron microscopy. RESULTS: 1) The neointimal area in injured arteries were significantly reduced in L-arginine supplemented animals compared with placebo group(p<0.05). 2) L-arginine administration significantly reduced the number of PCNA positive cells in neointima when compared with placebo at 9 days(p<0.05). 3) Positive TUNEL cells were not influenced by L-arginine supplementation. 4) On transmission electron microscopy, there were no cells showing characteristics of apoptosis in neointima. CONCLUSION: These results suggested that the inhibitory effect of L-arginine on neointima formation is due to reduced VSMC proliferation, but is not due to increased VSMC apoptosis at the early time period after initmal injur .

Bilateral tubal pregnancy is the least common type of all extrauterine pregnancies, 1:725-1:1580 of pregnancies are bilateral. Simultaneous tubal pregnancies have been reported in natural cycles, recently, after ovulation induction, assisted reproductive techniques. The high incidence of ectopic pregnancy assisted with ovulation induction continues to be a problem. Bilateral tubal pregnancy associated with the ovulation induction has been reported few cases of 3.0% to 6.0% in frequency. This paper describes a case of simultaneous bilateral tubal pregnancy after ovulation induction and intrauterine insemination in a 27 year old patient. The diagnosis was confirmed by laparoscopy performed 30 days after intrauterine insemination, which revealed bilateral tubal pregnancy and mild hyperstimulated ovaries. Bilateral salpingectomy was performed. With a review of the literature on this topic, diagnostic aspect and incidence and treatment options are discussed.

PURPOSE: This study evaluated the usefulness of ultrasonography for a diagnosis of acetabular labral tear in femoroacetabular impingement (FAI). MATERIALS AND METHODS: From March 2010 to October 2011, an ultrasonographic examination was performed in 58 patients(58 hips: 26 men and 32 women) with acetabular labral tear. The sensitivity and positive predictive value of ultrasonography were evaluated for 58 cases with acetabular labral tear confirmed by hip arthroscopy. RESULTS: The sensitivity and positive predictive value for an acetabular labral tear using ultrasonography was 89.6% and 100%, respectively. The concordance rate of an acetabular labral tear between arthroscopy and ultrasonography was 84.6%. CONCLUSION: Hip ultrasonography can make a significant contribution to a pathologic diagnosis and isa useful diagnostic tool for acetabular labral tears.

PURPOSE: A hypoechoic lesion is the most common finding of prostate cancer, but its diagnostic value is still an area of debate. The diagnostic significance of a hypoechoic lesion and the increased blood flow observed on transrectal ultrasonography (TRUS) were evaluated for the detection of prostate cancer. MATERIALS AND METHODS: The records of 266 patient's, between January 2003 and December 2005, were retrospectively reviewed. The cancer detection rates were compared according to the presence of a hypoechoic lesion in TRUS, and estimated with respect to stratification of the prostate- specific antigen (PSA) value and digital rectal examination (DRE) findings. RESULTS: The overall cancer detection rate was higher in the hypoechoic (40 of 101 cases, 39.6%) than in the isoechoic group (30 of 157 cases, 19.1%) (p<0.05). When the cases were divided into three groups, according to their PSA level (<4, 4-10 and >10), the cancer detection rate apparently increased in those with a hypoechoic lesion in TRUS (10.3 vs. 0%, 25 vs. 13.6% and 68.2 vs. 31% respectively) (p<0.001). Furthermore, the cancer detection rate was further increased in patients with a hypoechoic lesion than in those with an isoechoic lesion after division into two groups according to the presence of a hard nodule on DRE (with hard nodule, 56.9 vs. 46.7%; without hard nodule, 20 vs. 8.1%, respectively) (p<0.05). However, hypoechoic lesions with an increased blood flow did not improve the detection rate compared to those without (p>0.05). CONCLISIONS: The hypoechoic finding on TRUS not only supports the detection of prostate cancer, but also has independent diagnostic value. However, the findings of color Doppler are not helpful in the detection of prostate cancer.

The purpose of this study is to assess the usefulness of digital infrared thermographic image(DITI) in patients with surgically treated lumbar disc disease. A series of 480 patients with lumbar herniated disc was studied. The mean age of the patients was 37 years, with a range of 18 to 64 years. Of which 126 cases of chemonucleolysis. 18 cases of percutaneous endoscopic laser discectomy, and 336 cases of laminectomy with discectomy were performed. Among these patients, 336 cases of laminectomy were assessed by DITI preoperatively. The thermal differences(delta T) between the symptomatic and asymptomatic limbs were evaluated. We have categorized the types of herniations into 3 classes: 200 protruded, 99 extruded, and 37 sequestered. The thermal differences were classified into 3 groups: 177 patients had delta T < 0.5 degrees C, 74 patients had 0.5 degrees C < or = delta T < 0.8 degrees C and 85 patients had delta T > or = 0.8 degrees C. Among the group of patients with the sequestered disc, 30(i.e. 80%) had delta T > or = 0.8 degrees C. Among the surgically treated 336 patients, non-visualization of a part of the sciatic limb on preoperative DITI was the condition used to coin the term amputation sign by the authors. In the sequestered group, the "amputation sign" was observed in 28 cases(75%). We conclude that DITI can predict a sequestered disc disease, and it allows more precise indication regarding open surgery.

BACKGROUND: During coronary angiography, some electrocardiographic changes occured due to contrast media, which do life threatening influences. METHODS: We compared the electrocardiographic changes which were induced by injection of three radiopaque contrast media during selective coronary angiography in 49 patients with chest pain. One of the contrast media was high osmolar ionic(Urografin_76) and the another was low osmolar ionic(Hexabrix) and the last was non-ionic(Ioversol). Electrocardiograms were obtained before, during and after selective coronary angiography. RESULTS: The changes of S-T segment or T were decreased in non-ionic group rather than high osmolar or ionic group. And there was significant Q-Tc interval prolongation among all three groups except comparision of low osmolar ionic contrast dye and non-ionic contrast dye in left coronary angiography. CONCLUSION: Non-ionic low osmolar contrast media was safer than high osmolar or ionic contrast medial because of lesser change of Q-Tc interval during selective coronary angiography.

A paraurethral cyst is a rare congenital or acquired abnormality in females that is characterized by a round, yellow or orange-colored cystic mass on either side of the urethral meatus. We report a patient who presented with frequent, postvoiding dribbling. The important differential diagnostic considerations in infants and adults are an ectopic ureterocele, urethral diverticulum, cystocele and paraurethral tumors. Intravenous pyelography, voiding cystourethrogram, cystourethroscopy are essential for differentiating these lesions. This case of a paraurethral cyst was treated with complete excision.

The role of amino acids in culture media for IVF-ET was examined in a total of 76 cycles. Patients received clomiphene citrate (CC) followed by hMG or GnRH-a combined with gonadotropins (FSH/hMG) for controlled ovarian hyperstimulation. Severe male (<4 x10(6) motile sperm) or age factor (>39 y) patients were excluded in this study. Pregnancy was classified as clinical if a gestational sac or fetal cardiac activity was seen on ultrasound. No significant differences were found in age, duration of infertility, follicle size, the level of E2 on the day of hCG injection, the mean number of oocytes retrieved, total motile sperm count, fertilization rate and the mean number of embryos transferred between bHTF (without amino acids) and mHTF (with amino acids) groups. However, total ampules of gonadotropins were higher (p<0.01) in mHTF group than bHTF group. Significantly (p<0.05) more clinical pregnancies were recorded in mHTF group (13/30) compared with bHTF group (9/46). The multiple pregnancy rates were 11.1% in bHTF group and 77% in mHTF group. There were one ectopic pregnancy in mHTF group and one heterotopic pregnancy in bHTF group. Abortion rates were 22.2% in bHTF group and 7.7% in mHTF, respectively The ongoing pregnancy or livebirth .ate was significantly (p<0.05) higher in mHTF group (12/30) than bHTF group (7/46). These results suggest that the addition of amino acids in culture media is essential for culture of zygotes in vitro and adjustment of energy substrates in phosphate-free culture media appears to be beneficial for human IVF-ET procedure.
