The cystic lesions within the knee joint are rare, contrary to those located around the knee. They usually are eniscal or ganglion cyst, reported in association with the joint capsule of the knee or the menisci and close to the peroneal tendons. The intraarticular ganglion cyst arising from the cruciate ligaments are rare and cause pain, effusion and limitation of the knee joint. We report (he case of a patient with right knee joint pain caused hy an intraarticular ganglion cyst arising from the posterior cruciate ligament with review of reference.

We evaluated the corneal topography of 109 eyes which have 1 diopter or more astimatism, with computer-assisted videokeratography(Eye Sys CAS). There was 11% with round pattern, 17.4% with oval pattern, 49.5% with symmetric bow-tie pattern, 19.3% with assymmetric bow-tie pattern, 2.8% with irregular pattern. 70% of subjects had right and left eyes classified into the same group. There was statistically significant difference among the patterns for keratometric astigmatism and difference among the groups which were classified by the location of the area of highest refractive power for keratometric and total astigmatism. The mean angular separation between flat and steep meridian was 89.2 degrees and ranged from 78.61 degrees to 100.67 degrees. The mean residual astigmatism was 0.547 diopter. In the with-the rule astigmatism type, when the total astigmatism less than 1.89 diopter, residual astigmatism neutralize the corneal astigmatism, but when the total astigmatism increase more than 1.89 diopter, residual astigmatism tend to increase the total astigmatism.

OBJECTIVE: The laparoscopic appendectomy was developed as an alternative procedure to be used in acute appendicitis. Some surgeons dispute the advantages of laparoscopic procedures for acute appendicitis. Specifically, there are many controversies associated with perforated appendicitis. We reviewed the results of appendectomies to assess the feasibility of a laparoscopic appendectomy in acute appendicitis that included perforated appendicitis. METHODS: Three hundred thirty-nine consecutive patients with laparoscopic appendectomies, which include 27 patients with perforated appendicitis, were analysed. This study considered the lengths of the operation and the hospital stay. Differences in complications between non-perforated and perforated appendicitis were also evaluated. RESULTS: A total of 388 patients underwent appendectomies, 339 patients with laparoscopy and 49 patients with conventional open appendectomies, from April 1994 to June 1996. The mean duration of laparoscopic appendectomies was 48.9 minutes. This was slightly longer than that of open appendec tomies (44.9 minutes) in the same hospital. The duration of hospital stay was on the average of 4.9 days. Six patients (1.8%) were converted to conventional surgery because of difficult mobilization in 4 patients and uncontrollable bleeding in the remaining two. The surgeries on patients who were converted to conventional surgery were performed by rotating residents without staff supervision. Minor complications developed in eight patients (2.4%). In comparing the results between non-perforated and perforated appendicitis, durations of operation (47.3 vs. 78.3 minutes) and the hospital stay (4.6 vs. 8.6 days) were longer in perforated appendicitis. However, the complication rate (2.6 vs. 0%) was unexpectedly found to be lower in perforated appendicitis. CONCLUSIONS: The laparoscopic appendectomy is a safe, feasible procedure for acute appendicitis. It is an excellent procedure for perforated appendicitis and has minor complications compared to an open appendectomy with its large incision that is followed by a high rate of wound infection and/or post operative adhesion. There aree various reports on prospective randomized studies evaluating the benefits of a laparoscopic appendectomy compared to a conventional open appendectomy. The reports by laparo scopic surgeons in various centers are different with regard to operative time, postoperative recovery, morbidity, and postoperative complications. For complicated appendicitis, most surgeons are not in agree ment with the laparoscopic approach. We obtained excellent results with laparoscopic appendectomies in perforated appendicitis which included periappendiceal abscesses.

Background: According to the Diabetes Fact Sheet published by the Korean Diabetes Association, as of 2020, one in six adults (16.7%) over the age of 30 were diagnosed with diabetes. In this rapidly increasing prevalence of diabetes in Korea, the severity of diabetes to raise awareness of the importance of awareness, early detection, and active management. A public diabetes awareness survey was conducted in 2022 and 2023, and the survey contents by year were compared and presented. Methods: This survey was a structured online questionnaire conducted in October 2023, targeting a total of 1,000 adult men and women aged 20 or older nationwide through population proportional allocation according to age, sex, and residential area. Results: The survey results indicated that 91.4% of respondents perceive diabetes as a serious disease, and 68.3% of those without a diabetes diagnosis have expressed concerns about diabetes or hyperglycemia. However, awareness of ‘prediabetes’ and ‘glycated hemoglobin’ was only 61.3% and 38.1%, respectively. On the other hand, only one-third of the respondents reported maintaining an appropriate weight and waist circumference, eating regular meals, and engaging in regular exercise. While awareness and perceived necessity of insulin injections were high, the willingness to undergo injection therapy was only about 50%, indicating a need to provide information on the benefits of insulin therapy and its positive impact on quality of life. Conclusion Therefore, raising awareness about the severity of diabetes, along with education and intervention, is necessary to facilitate early detection and proactive management of diabetes.

OBJECTIVES: Leptin is a 16-kD protein encoded by the ob/ob gene and represent the amount of body fat. In pregnancy, it is thought to act in intrauterine fetal growth and energy metabolism. In this study, we investigated the effect of gestational age, fetal sex, maternal body mass index (BMI), and fetal weight estimated by ultrasound on amniotic fluid and maternal serum leptin levels at mid-trimester, respectively. METHODS: Amniotic fluid and maternal blood sampling were collected from women who was performed for genetic amniocentesis at mid-trimester (n = 26). Leptin concentrations were measured by a specific radioimmunoassay (RIA) employing human recombinant leptin. Mean gestational age was 18.19+/-1.77 weeks. Mean maternal BMI was 23.83 +/-5.12kg/m2. Male fetus was 10, and female 16. Mean fetal weight estimated by ultrasound was 254.42+/-83.80gm. RESULTS: Mean maternal leptin level( 12.49+/-4.46 ng/mL) was significantly higher than mean amniotic leptin level(5.06+/-3.20 ng/mL)( p = 0.0001) at mid-trimester. But there was no significant correlationship between maternal and amniotic leptin levels( p = 0.1376). Maternal leptin concentrations at mid-trimester were correlated positively with maternal BMI(y = 2.24 + 0.43 x, R2 = 0.494, p = 0.0103). In contrast, leptin levels in amniotic fluid did not correlate with maternal leptin levels, gestational age, fetal sex, maternal BMI, and fetal weight estimated by ultrasound respectively. CONCLUSION: Maternal leptin level was higher than amniotic leptin level and could represent maternal fat mass. It was suggested that amniotic leptin level was not associated with several factors such as maternal, fetal, and amniotic factors.

This study was performed to evaluate the effects of extracts of Drynariae Rhizoma on the characteristics of rat calvaria cells(RCV) and bone marrow cells(RBM) which have the important role on the bone formation in vitro. Drynariae Rhizoma has been known as the useful herbal medicament for treatment of the wound healing including regeneration of bone fracture, and also has been used to treat the periodontal lesions, tooth mobility, gingival bleeding and pus discharge via sulcus in Oriental Medicine. In control group, the cells were cultured alone with Dulbeco's Modified Eagle's Medium contained with 10% fetal bovine serum, 100U/ml penicillin, 100microgram/ml streptomycin, 0.5microgram/ml amphotericin-B. In experimental group, extracts of Drynariae Rhizoma(0.1, 1, 5, 10, 50microgram/ml) were added into the above culture condition. And then each group was characterized by examing the cell proliferation at 1, 3, 7, 14, 21, 30th day, the amount of total protein synthesis and alkaline phosphatase activity of RCV at 2,4th day and those of RBM at 3, 6th day. And also, the calcified nodule of RCV was examed at 3, 5th day in three goup, control, experimental, culture with the PDGF group. The results were as follow; 1. Both RCV and RBM cells in Drynariae Rhizoma-treated experimental group proliferated more rapidly than non-treated control group. The experimental group below 5microgram/ml Drynariae Rhizoma-treated showed more prominent cell proliferation from the 7th day to the 21st day than the control group and above 10 microgram/ml treated group in RCV. 2. Amount of total protein synthesis was more increased in Drynariae Rhizoma-treated group than in control group. In 5microgram/ml Drynariae Rhizoma-treated group showed most prominent protein synthesis of the any other exrperimental group and control group. 3. Alkaline phosphatase activity also more increased in Drynariae Rhizoma-treated group than control group.

PURPOSE: To measure the amount of type II collagen with western blotting method and to verify its relations with the clinical, radiological and second look arthroscopic findings in patients who were treated with microfracture surgery. MATERIALS AND METHODS: From October 1997 to December 2000, second look arthroscopies and biopsies were performed in 21 knees of 20 patients at 1 year after surgery. Their mean age at the time of operation was 62.7 years(range, 44-77years) and mean follow-up period were 1 year 3months(range, 10-30 months). 21 cases were classified into 3 groups (Group I >70%, Group II 20-70%, Group III < 20% of normal control) according to the result of western blotting of type II collagen. We analyzed the relationship of western blotting of type II collagen with clinical, radiological, extent of regenerated articular cartilage, patient's age, weight and preoperative varus deformity. RESULTS: Average amounts of type II collagen were 44% of those in control group. The amounts of type II collagen formation had positive correlation with extent of regenerated cartilage and preoperative varus deformity but no correlation with clinical score, joint space widening, patient's weight and age. CONCLUSION: The results of this study provide the rationale to select the osteoarthritic patients indicated for microfracture surgery.

Laryngotracheal injury following endotracheal intubation has been extensively described in the literature, but most discussion has centered around the sequela of prolonged intubation. Little however, has been reported regarding the lesions from short-term endotracheal intubation to ensure the safe practice of anesthesia. In this regard, 72 healthy, male patients undergoing general anesthesia for surgical procedures were randomly assigned to have an endotracheal tube of 7.0, 8.0, or 9.0 mm in internal diameter and were evaluated for the upper airway symptoms by questionnaire within 4-8 hours following extubation. The larynx and trachea were examined and scored for extent and severity of lary- ngotracheal damage by fiberoptic laryngotracheoscopy, and risk factors causing laryngotracheal injury were studied. The results were as follows; The incidence of upper airway symptoms were 13 of 72 (18.1%), of which 10 (13.9%) were throat discomfort and 3 (4.2%) were sore throat. The incidence of laryngeal and tracheal injury was 52 of 72 (72.2%) and 20 of 72 (27.8%), respectively. 20 patients (27.8%) did not reveal any lesion in the laryngotracheal system. The common sites of intubation injury were vocal cords (65.3%, all erythema) and arytenoids (44.4%, erythema 37.5%, edema 6.9%). No correlation could be drawn between the injured and uninjured groups with respect to smoking and length of intubation. However, bucking was associated with severity and extent of laryngeal damage (p<0.05), and with the extent of tracheal damage only (p<0.05). Also, the increase in internal diameter of the tube used was associated with severity and extent of laryngeal damage (p<0.05), but not with tracheal damage.
