Sacral perineural cyst is one group of extradural meningeal cyst at the sacral region. These lesions are distinguished from other spinal cysts because perineural cyst does not communicate with subarachnoidal space. Fluid filled cysts may compress adjacent nerve roots causing low back pain and sciatica which are dramatically improved by surgical excision. Differential diagnosis from other cysts can be accomplished by failure of collection of dye into cyst by initial myelography. C-T myelography rules out other mass lesions and often reveals communication of perineural cyst that filled with contrast medium. Magnetic resonance imaging well demonstrates three dimensinnal configures of an intraspinal cystic mass in initial study. However it is important to recognize that these cysts are one of causes of radiculopathy. We report three cases of sacral perineural cysts with radiculopathy.

The operative treatment of intraarticular calcaneal fractures has three principal aims; restoration of the height and width of the calcaneus, reconstruction of the subtalar and calcaneocuboid joint surfaces, and stable osteosynthesis. The purpose of this study is to demonstrate the effectiveness of the open reduction and internal fixation by the extended lateral approach for the treatment of the intraarticular calcaneal fractures. Twenty-one calcaneal fractures of 20 patients were treated by open reduction and internal fixation using an extended lateral approach from April, 1993 to March, 1994. The autogenous iliac bone graft was done in all patients. These patients were evaluated from 12 to 24 months (average 15.2 months) after surgery. The following results were obtained; 1. Seventecn cases (80%) out of 21 were estimated as good or excellent result. 2. Preoperative Bohler's angles, Gissane's angles and inclination angles were observed as average -0.5degrees, 101degrees and 38degrees respectively, and these were improved as average 23.3degrees, 117degrees and 54degrees, postoperatively. 3. There were two cases of skin necrosis as complication. In conclusion, the extended lateral approach is one of the good methods for the treatment of intraarticular calcaneal fractures. We think that accurate reduction of the posterior facet, acceptable recovery of Bohler's angle and early postoperative mobilization are the most important things for the best result of the intraarticular calcaneal fracture surgery.

BACKGROUND:We performed this study to determine the influence of the administration of pneumoperitoneum on the blood flow of the thoracoabdominal aorta during laparoscopic cholecystectomy (LC). METHODS: Ten patients for LC were enrolled in this study. Anesthesia was performed with propofol, fentanyl and rocuronium. Pneumoperitoneum was made by CO2 gas intraperitoneal instillation at an intraperitoneal pressure of 10-12 mmHg. Peak velocity of blood flow in the systolic phase (PV), mean acceleration of blood flow from the start of systole (MA) and systolic flow time corrected for heart rate (FTc), measured by esophageal doppler monitoring (EDM), and heart rate (HR) and mean brachial BP (MBP) were measured 1, 5 and 10 min after the institution of pneumoperitoneum, (T1, T5 and T10) and compared with those before the institution of pnuemoperotoneum (T0). LC was started after recording all measurements and a position change to the reverse-Trendelenberg position. RESULTS: PV, MA, FTc and HR showed no significant change throughout this study, but MBP at T5 and T10 (110.1 +/- 18.5 mmHg and 107.8 +/- 10.4 mmHg) were significantly higher than at T0 (84.9 +/- 12.9 mmHg) (P = 0.002 and 0.005 respectively). CONCLUSIONS: The administration of pneumoperitoneum neither changed nor interferenced with abdominal aortic blood flow.

OBJECTIVE: Our previous study demonstrated that the placental GnRH and GnRH mRNA did not parallel the time course of hCG secretion, though it is thought to be one of the potential paracrine regulators of hCG secretion from the trophoblasts. The present study was designed to examine the potential variation in GnRH-receptor mRNA expression in the placenta, which may account for the GnRH-mediated action of hCG secretion during pregnancy. METHODS: Human placentas in firt, second, and third trimester of normal pregnancy were obtained. These placentas were fixed with 4% paraformaldehyde and embedded in OCT compound, and sectioned by cryostat. For in situ hybridization, S labeled RNA probes were used and followed by autoradiography. RESULTS: The GnRH-receptor mRNA signals were present in both cytotrophoblast and syncytiotrophoblast cell layers. Signal intensities varied with gestational ages and were abundant at 6-7 weeks, peaked at 9-12weeks, declined at 14 and 24 weeks, and were barely detectable at term. The present study demonstrates that GnRH-receptor mRNA exhibits changes paralleling the time course of hCG secretion during pregnancy CONCLUSION: These data provide mechanistic understanding that the paracrine/autocrine regulation of hCG secretion by placental GnRH is mediated through an increase followed by a decline in GnRH-receptor mRNA expression from the first trimester to term placenta.

Nonpalpable breast abnormalities which require excision and biopsy usually require marker localization. Many of these abnormalities are visible on ultrasound and this imaging technique can be used to guide fine needle aspiration and the placement of a wire marker prior to surgical excision. A non-invasive technique which does not require placement of a wire marker would offer significant advantages, being more pleasant for the patient and less demanding on resources. We attempted to localize 36 nonpalpable breast masses with non-invasive ultrasound marker technique at the department of general surgery, Soon Chun Hyang University Hospital, between January 1994 and February 1995. Cases clearly visible on ultrasound, whether on mammography(15 patients) or not(17 patients), underwent non-invasive ultrasound localization. In all cases the abnormality was easily identified and removed during surgery. The surgical biopsies contained fibroadenoma(19 cases), fibrocystic disease(12 cases), epithelial hyperplasia(1 case), intraductal papilloma(1 case), parasitic disease(1 case) and infiltrating ductal carcinoma(2 cases). The average age was 43 years old.. This non-invasive technique is a simple and accurate method for localizing small ultrasonically visible nonpalpable breast abnormalities, especially in younger female patient with dense breast, though further trials and studies will be attempted.
