OBJECTIVE AND METHODS: To determine correlations among ambulatory renin activity, ambulatory blood pressure and microalbumin excretion rate, 66 Korean essential hypertensives were studied after 4 week wash-out period. The ambulatory blood pressure was monitored every 30 minutes and mean BP were calculated automatically. Urinary microalbumin excretion rate(UAER) and ambulatory plasma renin activity(aPRA) collected at mid-day were measured by radioimmunoassays. Subjectives were divided into 2 groups by aPRA value(2ng/ml/hr). RESULT: 14 cases were high renin group and 52 cases low renin group. The mean BP were 148.83/94.69mmHg in low renin group, and 146.57/98.07mmHg in high-renin group without difference. UAER were not different also between both groups. 23.07%(4/14) of non-dippers were included in high renin group and 25.58%(12/52) in low renin group without statistical difference. The aPRA was significantly related to UAER and systolic and diastolic mean blood pressure. Also UAER was related significantly to day mean blood pressures. CONCLUSION: Thus aPRA is thought to be a meaningful indicator to predict hypertensive renal target organ damage as well as blood pressure measured with 24-hr ABPM.

PURPOSE: The aim of this study was to review the outcome of local control after the local excision for T1/T2 rectal cancers and, thus, to assess its effectiveness as an alternative to a more radical resection. METHODS: This retrospective study analyzed 23 patients with T1/T2 rectal cancer treated by local excision (LE), and their results were compared with the results for 22 patients with rectal cancer of the same stage treated by a radical resection (RR). All patients with pT2 lesions in the LE group received postoperative adjuvant chemoradiation. The outcomes were defined as 5-year local-recurrence-free survival (LRFS). The median follow-up was 72 (range, 40~92) months. RESULTS: Recurrence occurred in 4 patients (pT1, 1; pT2, 3) in the LE group and in 3 patients (all pT2) in the the RR group. One patient with vascular invasion (T2N1M0) in the RR group showed multiple liver metastases at 23 months postoperatively. The difference in 5-year LRFS was not statistically significant between the two groups. In the LE group, the 5-year LRFS for pT2 lesions was significantly less favorable than that for pT1 lesions (40% vs. 94%; P= 0.005). The 5-year LRFS for pT2 in the RR group was more favorable than that in the LE group, although the difference was not statistically significant (76.9% vs. 40%, P=0.138). CONSLUSIONS: Local excision provides a favorable local control for pT1 rectal cancers. A more radical resection, however, remains an effective surgical option for pT2 lesions because local excision, even combined with adjuvant chemoradiation, showed substantial local recurrences.

High-resolution (HR) ultrasound, which has been progressing continuously in technology, has improved in aspect of spatial and contrast resolution. The HR ultrasonography is a noninvasive, readily applicable imaging technique, which could get static and dynamic image in real-time for various neuromuscular disorders, especially in entrapment neuropathy. It is also a reliable tool to detect dynamic muscle movements such as fasciculation as well as muscle atrophy in chronic myopathies or neuropathies. Although reliability of the HR ultrasonography has not been investigated in large series of patients, different neuromuscular disorders tend to show specific changes on the ultrasound, which can be helpful in differential diagnosis. The HR ultrasonography is an ideal tool for the clinical and research investigation of neuromuscular system complementary to electrodiagnostic studies. This review briefly describes applicability for various neuromuscular disorders with previous study results and the technical aspects of ultrasound and its physical principles.

Primary intracranial choriocarcinoma is a extremely rare neoplasm since the case was reported by Askanasy, in 1906, there have been 35 reported, even if germinal neoplasms containing chorocarcinoma-like tissue are added. But pure choriocarcinoma was rarely reported. The purpose of this paper is to report a case of 18-year-old boy with tumor in subependymal region around left frontal horn, which was present with high level of serum beta chain of chorionic gonadotropin(B-HCG) and was verified as germine choriocarcinoma by biopay.

PURPOSE: Necrotizing enterocolitis (NEC) is one of the most common surgical emergencies during the neonatal period. The aim of this study was to identify and assess the factors affecting the postoperative mortality in infants with NEC that require surgical treatment. METHODS: The authors retrospectively reviewed 37 infants surgically treated, at the Department of Surgery, Pusan National University Hospital, between Jan. 2000 and Dec. 2004. The patients were divided two groups according to the clinical outcomes; the survival and non-survival groups. Eight variables, i.e., sex, gestational age, weight at birth and at the time of the first operation, weight change between birth and the time of the first operation, degree of clinical manifestations (as a modified Bell's stage), interval between the onset of symptoms and the time of the first operation, the extent of necrotic intestine and associated anomalies, were analyzed. RESULTS: Among 37 infants, 6 expired (a mortality rate of 16.2%). The postoperative mortality was not affected by sex, gestational age, and the weight at birth and at the time of the first operation, weight change between birth and at the time of the first operation, degree of clinical manifestations and the interval between the onset of symptoms and the time of the first operation. However, the extent of necrotic intestine was associated with a significantly increased mortality (P=0.046). CONCLUSION: These data suggest that the extent of necrotic intestine is the only statistically significant factor affecting the postoperative mortality in infants with NEC that require surgical treatment.

PURPOSE: Obese patients are generally believed to be at increased risk for surgery compared to those who are not obese. It was the purpose of this study to compare the short-term outcomes of a laparoscopic low anterior resection (LAR) in obese and non-obese patients. METHODS: We retrospectively reviewed 79 patients who had undergone a laparoscopic LAR for rectal cancer between September 2002 and January 2008. The degree of obesity was based on the Body Mass Index (BMI, kg/m2). We divided the 79 patients into two groups: the high BMI (BMI> or =25) and the low BMI (BMI <25) groups. The parameters analyzed included age, gender, American Society of Anesthesiologists classification score, operative time, estimated blood loss, conversion rate, postoperative complications, hospital stay, and oncologic characteristics. Statistics included the t-test and Fisher's exact test. Statistical significance was assessed at the 5% level (P<0.05 being statistically significant). RESULTS: There were no significant differences between the low BMI (n=55) and the high BMI (n=24) groups in age and gender. The high BMI group had significantly more conversion to an open procedure (20.8% vs. 3.6%, P=0.0244). The high BMI group and the low BMI group had no differences in blood loss, complications, hospital stay, and oncologic characteristics, but the high BMI group had a longer operative time (244.2 min vs. 212.0 min, P=0.0035). CONCLUSION: A laparoscopic LAR in obese patients had a higher conversion rate and a longer operative time, but there were no differences in postoperative complications and oncologic characteristics. A further study based on many experiences is needed to clarify the influence of the surgeon's experience on the operative time and the conversion rate, and long-term follow-up is necessary to evaluate the oncologic safety of a laparoscopic LAR in obese patients.

PURPOSE: In the management of Hirschsprung's disease (HD), conventional Duhamel's, Swenson's or Soave's procedures have generally been performed. The author tried a new procedure, a transanal one-stage pull-through procedure (TOP). The aim of this study is to compare functional outcome of TOP with the conventional procedures that are generally used in treating HD. METHODS: Thirty-one cases received TOP procedure from November 2000 to December 2003. The postoperative results were evaluated by performing a retrospective medical record review, and by using as questionnaire. These results were then compared with reports' on patients after using one of the conventional procedures. RESULTS: In this study, the mean age of patients was 73.4 days, the mean hospital stay was 5.7 days and the mean follow-up period was 20.1 months. Postoperative results were as follows: (1) 23 cases (74.2%) had 1~2 times of defecation per day. (2) 26 cases (83.9%) had no problematic soiling. (3) 22 cases (70.9%) had soft consistency of stool. (4) 24 cases (77.4%) had no straining during defecation. (5) 25 cases (80.7%) didn't need stool softner. (6) In 14 cases (45.2%), an anal dilator was necessary for transient postoperative anal stricture. (7) After 24 months of age, a diaper was not necessary in 12 cases (70.6%). (8) The parents felt satisfactory in 28 cases (90.3%) for their children, as compared with the children from other families, and the parents felt satisfactory in 18 cases (94.7%) for the HD children compared with the other children of their family.(9) 23 cases (74.2%) had not shown constipation findings on simple abdomen film. (10) At the first digital rectal examination, perianal rash was found in 13 cases (41.9%), anastomotic stricture had occurred in 12 cases (38.7%), and normal squeezing pressure was felt in 27 cases (87.1%). However, at the last examination during the follow-up period, perianal rash was found in 2 cases (6.5%), the anastomotic stricture had not persisted, and normal squeezing pressure was felt in all cases (100%). (11) On the barium study, 13 months after operation, no retention of contrast within 24 hours was shown in 21 cases (95.5%). (12) According to the SanFilippo system, there were 24 excellent cases (77.4%) and 7 good cases (22.6%), so all the cases showed a favorable functional outcome. (13) In comparison with other reports' results, there was no significant difference between the author's outcomes and other reports' outcomes (p=0.752). CONCLUSION: This transanal one-stage pull-through procedure (TOP) seems to be as effective as the traditional method for the management of HD.

The systolic time intervals were measured in 25 normal controls and 23 patients with dilated cardiomyopathy by simultaneous recording of the aortic valve echocardiogram and ECG. These values were compared to corresponding ones obtained from the method using simultaneously recorded phonocardiogram, ECG, and indirect carotid pulse tracings. And we assessed left ventricular function by systolic time intervals in dilated cardiomyopathy. The results were as followings. 1) High degree of correlation(r> or =0.94) was found between the two methods for each intervals, EMS, LVET, PEP, PEP/LVET. 2) In normal controls, PEP/LVET obtained from echocardiographic measurement was 0.31+/-0.02. 3) In the patients with dilated cardiomyopathy, PEP/LVET(0.59+/-0.13) was significantly higher(p<0.001), PEP index was longer(p<0.05), LVET index was shorter(p<0.05) than in normal controls.
