Scapular fractures are being seen with increasing frequency in our mechanized society, specially in patients who have multiple injuries. Most of the scapular fractures have been treated non-operatively, with early mobilization of the shoulder. The result of such functional treatment have been predictably good. However, this non-operative approach may not yield such good results in patients who have a fracture of the scapular neck in association with the ipsilateral clavicular fracture or other double disruptions of the superior shoulder suspensory complex. Ipsilateral fractures of the scapular neck and clavicle disrupt the suspensory mechanism of the shoulder resulting in fuctional loss and deformity. From January 1989 to June 1995, twelve patients were identified with this specific pattern of injury. The follow up period was 39.2 months in average. Seven patients were treated operatively using 3.5mm DCP or reconstruction plate, and five patients were performed K-wire fixation or wiring. Upon review all were healed radiographically. According to the scoring system of Rowe, five patients had an excellent fuctional result, five had a good result, and two had a fare result. The average score for the twelve patients was 85 points. The results of our retrospective study show that operative treatment for these complex fractures is safe and that functional recovery is predictably good.

Supracondylar fracture of the humerus in children is the most common fracture of the elbow in contrast with infant or adult, and there are also many problem in treatment and accompanying complication. These injuries are difficult to manage in case of a delayed initial treatment or repeated close manipulation. We analysed 32 cases which failed and delayed initial management, at department of orthopedic surgery, Chung Nam University Hospital from Jan. 1977 to Dec. 1981. The results obtained were as follows: 1. The cases admitted after unsatisfactory treatment at other hospital among all cases are most common (59.4%). 2. The average duration after trauma are 5.3 days. The average duration until successful reduction after initial trauma are 7.3 days, 3. In types of fracture, there are all displaced supracondylar fracture (Type II, III, IV). 4. In treatments, initial sucessful close reduction are 5 cases (15.6%). The others require other managements, ie, final successful tractions are 5 cases, final sucessful percutaneous pinnings are 5 cases and final open reductions are 16 cases. 5. Cubitus varus deformity was more common in manual reduction and traction groups than in open reduction and percutaneous pinning groups, but limitation of elbow motion was more common in open reduction and percutaneous pinning groups. 6. In complications, there were 5 nerve palsies (4 radial nerves, 1 median nerve), 3 pin tract infections, 1 myositis ossificans, 9 severe cubitus varus and 5 severe limitation of motion.

The purpose of this study is to compare the effects of the femoral attachment points of the graft and knee flexion angles at the time of graft fixation on stability of posterior cruciate ligament reconstruction. We analyzed the posterior stability of the knee on 23 patients(24 knees) with posterior cruciate ligament injury whose posterior cruciate ligament had been reconstructed arthroscopically and followed for minimum 1 year period at Asan Medical Center from May 1992 to June 1994. The patients were divided into the two groups according to femoral attachment points of the graft and knee flexion angles at the time of graft fixation. The distance from the junction of the intercondylar notch with trochlear groove of the femoral attachment points and knee flexion angles were 11mm and 0°-30° in group A and 7mm and 70°-90° in group B, respectively. 11 knees were included in group A and 13 knees in group B. Posterior stability was determined by difference in posterior tibial translation between the injured and the opposite knee with Telos device. In group A, 5 cases were at the range of 0-2mm, 3 cases 3-5 mm, 3 cases 6-10mm. In group B, 10 cases were at the range of 0-2mm and 3 cases 3-5mm, respectively. Differences in posterior tibial translation on average were 3.6mm and 1.7mm in group A and B, respectively. Conclusively, arthroscopic postrior cruciate ligament reconstruction with femoral attachment point at 7mm from the junction of interconlylar notch with trochlear groove and 70°

The retraction of anterior teeth could be performed more easier by inducing of skeletal anchorage system rather than by conventional method on orthodontic treatment. But, we wonder how effective the system draws well without anchorage loss and draws anterior teeth aside posteriorly, and if the system can reduce the time, in comparison with the anchorage of posterior teeth. For that reason we have studied on the subject of patients, who were required the maximum anchorage on orthodontic treatment and the cases without crowding. The subjects of the experimental group are 35 areas of 20 people who were inserted miniscrews after Mx or Mn 1st premolar extracted. Also, the subjects of the control group are 81 areas of 45 people who were not inserted miniscrews. Compared the anchorage loss of experimental group with control one, we could get the result that the anchorage loss of experimental group is 1.034+/-0.891mm and control group is 2.790+/-1.882mm(P<0.01). Compared the space closing time of experimental group with control one, we could get the result that the space closing time of experimental group is 369.40+/-110.81days and control group is 406.56+/-231.63days. But the result of comparing space closing time has no significance in statistics. We recognized that the experimental group is more faster than the control group in the canine retraction velocity from the result ; the speed of a experimental group has as much as 0.60+/-0.23mm/30days while the speed of a control group has 0.44+/-0.35mm/30days(P<0.05). So, we could convince that orthodontic miniscrew is used effectively in the cases required the maximum anchorage.

The contour of mandibular angle is important for facial esthetics in the oriental population, because the wide and square face is thought to have had an unhappy life. A prominent mandibular angle produces a characteristics quardrangle, coase, and muscular appearance. So, uni- or bi-lateral mandibular angle reduction is usually performed. However, there is little guideline for bi-lateral angle reduction. So, this study was to investigate the pattern of Korean mandibular angle for bi-lateral mandibular angle reduction as guideline. This study was included 66 adult men and women over 19 years old who are having the normal mandibular angle. We measured the posterior border, angle, and inferior border of mandible using cephalometric view. The results of study was as followed : 1. The ratio of posterior mandible was 96.6, 97.3% in male, and 103.0, 106.0% in female. 2. The ratio of mandibular angle(R1-Go/R1-R2) was 120.2% in male, and 117.3% in female. 3. The ratio of inferior mandible(D5, 6, 7, E, F, G/D4) was 97. 3, 90.9, 79.5, 65.2, 57.8, 46.9% in male, and 98.5, 91.2, 80.5, 67.6, 59.1, 50.2 % in female. The results of this study should be useful to decide accurate amount of reduction.

Recent advancements in various technologies have shed light on the critical role of metabolism in immune cells, paving the way for innovative disease treatment strategies through immunometabolism modulation. This review emphasizes the glucose metabolism of myeloid-derived suppressor cells (MDSCs), an emerging pivotal immunosuppressive factor especially within the tumor microenvironment. MDSCs, an immature and heterogeneous myeloid cell population, act as a double-edged sword by exacerbating tumors or mitigating inflammatory diseases through their immune-suppressive functions. Numerous recent studies have centered on glycolysis of MDSC, investigating the regulation of altered glycolytic pathways to manage diseases. However, the specific changes in MDSC glycolysis and their exact functions continue to be areas of ongoing discussion yet. In this paper, we review a range of current findings, including the latest research on the alteration of glycolysis in MDSCs, the consequential functional alterations in these cells, and the outcomes of attempts to modulate MDSC functions by regulating glycolysis. Ultimately, we will provide insights into whether these research efforts could be translated into clinical applications.

To estimate the incidence of externally recognizable genitourinary anomalies and associated anomalies in the newborns in Korea, retrospective and prospective studies have been performed. Thirty eight of 48 urology training hospitals participated in this nationwide survey. In this study we have included minor defects or variations in the anomaly to evaluate the incidence of the recognizable genitourinary conditions in the newborns. The incidence of genitourinary anomaly in 1,000 newborn delivery in a year was 11.0 in the prospective study and this figure is about three times higher than the retrospective study and is considered to be close to the true incidence. The incidence of genitourinary anomaly in 1,000 male newborn was 20.4. Hydrocele, cryptorchidism and hypospadias were most commonly observed. The incidence of hydrocele in 1,000 male newborn was 9.89 and the incidence of cryptorchidism was 7.26 and the incidence of hypospadias was 2.13. The incidence of associated anomaly in 100 genitourinary anomaly was 7.9. Congenital heart diseases and anorectal anomalies were commonly associated anomalies. In the newborns with genitourinary anomalies, premature infants account larger portion than is usually reported in total delivery.

BACKGROUND: Although pain after cholecystectomy was reduced significantly since the advent of laparoscopic surgery, many patients still complain of moderate pain after the surgery. Recently intraperitoneal instillation of local anesthetics is known as safe, simple, and effective method of treatment for pain after laparoscopic cholecystectomy. METHODS: Three groups are randomized; group I (normal saline 80 ml), group II (0.5% lidocaine 80 ml+1:400,000 epinephrine) and group III (0.125% bupivacaine 80 ml+1:400,000 epinephrine). Local anesthetics are instilled via subdiaphragmatic trocar hole just after creation of carboperitoneum. Visual analogue scale (VAS), total used analgesics amount, time to first analgesics request, time to out of first flatus and complications are compared. Lidocaine blood concentrations are checked in five cases of the patients after lidocaine instillation. RESULTS: The VAS was insignificant among groups except 3 hr, 6 hr postoperatively. Time to first analgesics request are prolonged in lidocaine and bupivacaine group. Used analgesics amount are significantly less in lidocaine group than control group. Time to out of first flatus was significantly shorter in bupivacaine group. No significant complications were noted. The blood concentration of lidocaine were variable and the highest concentration in five of one case was 1.8 microgram/ml. CONCLUSIONS: Although intraperitoneal instillation of local anesthetics is simple, safe method for controlling pain after laparoscopic cholecystectomy, it is not so much effective because of dilution with irrigating saline and suctioning intraoperatively and postoperative scavenging by evacuator.
