Purpose: A laparoscopic radical nephrectomy is known to cause less morbidity than a traditional open radical nephrectomy. In our institution, the laparoscopic approach, with intact specimen removal, has become the standard technique for radical nephrectomies. Herein, we report the results and oncological outcome of the experience of a single center. Materials and Methods: We reviewed 68 transperitoneal laparoscopic radical nephrectomies, performed for suspected renal cell carcinoma between December 1999 and June 2006. All data were collected from the patient's medical records. Results: The mean tumor size, surgical time and estimated blood loss were 4.82cm (1.7-14), 228.5 min (120-480) and 409.1cc (32-1,312), respectively. Conversion to open surgery was required in one case due to Endo-GIA malfunction, and conversion to hand-assisted surgery was performed in one case. The histological findings were pT1, pT2 and pT3 in 40 (59.7%), 9 (13.4%) and 18 patients (26.9%), respectively. In one case, the histology confirmed a non-malignant disease. The follow-up period was from 3 to 80 months (median 18). Distant metastasis was observed in 2 cases, but there was no local recurrence or port metastasis. Conclusions: A laparoscopic radical nephrectomy is a safe and feasible treatment for localized renal cell carcinomas. Longer follow-up and large scale studies are necessary to evaluate the long-term survival and disease- free rates, and confirm the effectiveness of performing a radical laparoscopic nephrectomy.

PURPOSE: To evaluate the usefulness and effectiveness of endoscopic management for recurrent hematospermia, we performed transurethral endoscopy of the seminal vesicles in patients with recurrent hematospermia, despite the administration of oral medication. MATERIALS AND METHODS: Sixteen patients were enrolled this study. Initially, all patients were treated with oral antibiotics for 6-8 weeks. Transrectal ultrasound (TRUS) and/or MRI were performed to find the anatomic abnormality and its relation with pelvic organs. The mean patient age and duration of symptoms were 43.9 years (range 24-64 years) and 21.3 months (range 1-108), respectively. We used a 6.5Fr. rigid ureteroscope and/or 14Fr. endoureterotomy instruments for the seminal vesiculoscopic examination. Patients were followed for more than 12 months after the procedures. RESULTS: An endoscopic seminal vesicle examination was able to be successfully performed in all patients. A midline cyst was found at 10 cases, which were fulgurated. Endoscopic incisions or dilation of the ejaculatory duct were performed in all patients. An ejaculatory duct stone was found at 5 cases, and removed endoscopically. All patients reported improvement of hematospermia after the procedure, and 3 with perineal discomfort became symptom free. Postoperative complications, such as epididymitis, orchitis and ejaculatory abnormalities, were not observed in any patient. CONCLUSIONS: Transurethral endoscopic interventions of the seminal vesicles can be performed easily with a conventional 6.5Fr. rigid ureteroscope and/or 14Fr. endoureterotomy instruments. Transurethral endoscopic managements were effective and safe treatment options in recurrent hematospermia patients.

PURPOSE: The aim of this study was to assess the usefulness of growth velocity at 3 months after gonadotropinreleasing hormone (GnRH) agonist treatment as a predictive value of 1 year growth velocity after treatment in girls with precocious puberty. METHODS: We studied 30 Korean girls with precocious puberty whose chronologic and bone age were less than 9 years and 11 years old, respectively at diagnosis. They treated with a 4 week interval GnRH agonist subcutaneous injections for at least more than 1 year. The patients who were treated with growth hormone simultaneously excluded for this study. Data were collected from chart review retrospectively. We measured heights and calculated growth velocities of the subjects at 3 months and 1 year after GnRH agonist treatment. RESULTS: The mean chronologic age and bone age of the subjects were 8.3 +/- 0.8 year and 10.4 +/- 0.6 years, respectively. The growth velocity at 3 months, 6 months, 9 months and 1 year after GnRH agonist treatment were 7.1 +/- 2.6, 6.6 +/- 2.1, 5.7 +/- 1.3 and 5.8 +/- 0.9 cm/yr, respectively. The positive correlation between the growth velocity at 3 months and 6 months, 9 months, 1 year after GnRH agonist treatment were shown(P < 0.001, P < 0.001, P = 0.002, respectively). CONCLUSION: In this study, the growth velocity at 1 year after GnRH agonist treatment may be predicted by the growth velocity at 3 months after treatment. The patient whose growth velocity at 3 months after GnRH agnoist treatment was low would be needed to observe the growth pattern carefully and to consider combined growth hormone treatment, if needed. It may be deserve further studies to improve final height in patients with central precocious puberty in various conditions.

Objective: Although serum ferritin is considered the best measure of total body iron, with low levels indicating iron deficiency, recent studies have shown that high levels are associated with gestational diabetes, premature birth, and low birth weight. This study aimed to analyze the association between serum ferritin levels in the third trimester of pregnancy and low birth weight and preterm birth. Methods: This study included pregnant women who delivered a single fetus at Kangwon National University Hospital between January 2009 and December 2013 and in whom serum ferritin levels were measured between 28 and 34 weeks of gestation. The association between serum ferritin levels measured in the early third trimester of pregnancy and preterm birth and low birth weight infants was analyzed. Results: A total of 1,079 women fulfilled the study criteria and had their serum ferritin level measured during the third trimester (28–33.9 weeks of gestation) and later delivered at Kangwon National University Hospital. Comparison of the group with serum ferritin levels above the 75th percentile and those below the 25th percentile at the beginning of the third trimester revealed that the incidence of preterm births (<34 weeks of gestation, <37 weeks of gestation) and low birth weight were significantly higher in the group with serum ferritin levels above the 75th percentile than those below the 25th percentile (p<0.05). When variable factors were controlled through multiple regression analysis, the group whose serum ferritin levels were above the 75th percentile at 30–31.9 weeks of gestation had the highest risk of preterm birth before 34 weeks of gestation (adjusted odds ratio [OR], 7.85; 95% confidence interval [CI], 1.32–29.9) and low birth weight (adjusted OR, 6.49; 95% CI, 2.10–20.0). Conclusion In this study, when serum ferritin was high in the third trimester of pregnancy, it was significantly increased with preterm birth (<34 and 37 weeks) and low birth weight. In particular, when serum ferritin levels were high at 30–31.9 weeks of gestation, the risk of premature birth before 34 weeks and low birth weight was statistically highest.

BACKGROUND: Anesthesiologist must be aware of the common problems that occur in pediatric anesthesia. The purpose of this survey was to collect information to help improve the quality of pediatric anesthesia by comparing the opinions of anesthesiologists that treat children and those that do not treat children. METHODS: A questionnaire surveying the attitudes of 103 anesthesiologists with regard to pediatric problems was analyzed. The questionnaire inquired about the number of years worked in field, the form of work and the responsibilities with regard to the pediatric anesthesia. Each question was rated from 1 (very infrequent) to 5 (very common) for the frequency of problems and from 1 (not importance) to 5 (very important) for the importance of the problem. Then we calculated the average of each item and combined the scores to obtain an average frequency and an average importance. RESULTS: The list of problems had high combined scores for preoperative anxiety (10.62), incision pain (9.59), postoperative agitation (9.53), hypothermia (9.40), and vomiting (9.30) for the pediatric anesthesiologist group. In addition, the problem list had high combined scores for propofol injection pain (11.25), preoperative anxiety (10.92), vomiting (10.17), hypothermia (9.44), and postoperative agitation (9.42) for the non-pediatric anesthesiologist group. CONCLUSIONS: The results of this study showed a difference in the pediatric and non pediatric anesthesiologist groups for propofol injection pain. Differences were noted for the average importance (2.34 : 2.80) compared to the average frequency (3.93 : 4.01). The pediatric anesthesiologists regarded propofol injection pain to be less of a problem than did the anesthesiologists who did not care for pediatric patients.

Fat embolism syndrome is a rare and potentially lethal complication most commonly seen in long bone fractures and intramedullary manipulation. The clinical triad of fat embolism syndrome consists of mental confusion, respiratory distress, and petechiae. This study reports a case of cerebral fat embolism syndrome following elective bilateral total knee replacement. After an uneventful anesthesia and initial recovery, the patient developed neurologic symptoms nine hours postoperatively.
