Purpose: We wanted to evaluate the clinical and radiologic results of acetabular revision using the acetabular reinforcement ring and also the allograft impaction in the acetabulum having deficient bone stock. Material and Methods: Nineteen hips revision arthroplasty were performed in 18 patients (9 males and 9 females) with using an acetabular reinforcement ring and allograft between July 1993 and December 2003. The patients were followed for an average of 64 months (range: 24-153). The mean age at the time of arthroplasty was 59 years old (range: 34-76). The causes of revision were aseptic loosening of the acetabular component in 16 cases, severe progressive osteolysis around the acetabular component in 2 cases and Girdlestone state after infected total hip arthroplasty in one case. The acetabular deficiency was type II in 5 hips, type III in 13 hips, and type IV in one hip according to the AAOS classification. The clinical results were evaluated using the modified Harris hip score, and the radiologic results were evaluated by assessing the preoperative and serial follow-up radiographs. Results: The mean preoperative Harris hip score of 47 was improved to 86 points at the latest follow-up. Periacetabular osteolysis was found in 2 cases, which did not progress at follow-up. The anatomic hip center was restored after revision arthroplasty (p<0.05). Complications were dislocation in 2 cases, breakage of the hook of the Ganz ring in one case, heterotopic ossification in one case and femoral artery injury in one case. All cases showed stable fixation of the acetabular component and good remodelling of the impacted allograft. There was neither recurrence of dislocation nor progression of the acetabular component loosening on the radiographs. Conclusion: Acetabular revision with acetabular reinforcement ring and allograft impaction showed satisfactory clinical and radiologic results with restoration of the hip center and consolidation of the allograft.

Gastric cancer is the second most common cause of cancer-related death in the world. A growing body of evidence indicates that inflammation is closely associated with the initiation, progression, and metastasis of many tumors, including those of gastric cancer. In addition, approximately 60% of the world's population is colonized by Helicobacter pylori, which accounts for more than 50% of gastric cancers. While the role of inflammation in intestinal and colonic cancers is relatively well defined, its role in stomach neoplasia is still unclear because of the limited access of pathogens to the acidic environment and the technical difficulties isolating and characterizing immune cells in the stomach, especially in animal models. In this review, we will provide recent updates addressing how inflammation is involved in gastric malignancies, and what immune characteristics regulate the pathogenesis of stomach cancer. Also, we will discuss potential therapeutics that target the immune system for the efficient treatment of gastric cancer.

PURPOSE: Asymptomatic urinary retention in the post-partum period is a relatively common problem. We investigated prospectively the incidence and the various risk factors associated with asymptomatic urinary retention in post-partum. MATERIALS AND METHODS: From Feb. 1999 to Apr. 1999, all pregnant women who visited our hospital for delivery were evaluated. Among them 103 women who had undergone vaginal delivery were evaluated, Exclusion criteria were cesarean section, incidental catheter indwelling during delivery, and symptomatic urinary retention. Residual urine volume was measured using BladderScanTM BVI 2500(Diagnostic Ultrasound co.) within 10 minutes after first voiding in immediate post-partum period. Asymptomatic urinary retention was defined as residual urine volume over 150ml. Pre-partal urinary symptoms and various obstetric parameters were evaluated in asymptomatic urinary retention group and normal group as control. Asymptomatic urinary retention group were followed up daily to monitor their post-void residual urine volume. RESULTS: The incidence of asymptomatic urinary retention after vaginal delivery was 13.6%. Factors associated with asymptomatic urinary retention included second stage of labor, episiotomy, and instrumental delivery. There was no relationship between pre-partal lower urinary tract symptoms and post-partal asymptomatic urinary retention. In patients with asymptomatic urinary retention, catheterization was done for removing residual urine and thus preventing progression of further distension. Post-void residual volume was normalized within 3 days in all patients. CONCLUSIONS: Asymptomatic post-partum urinary retention is a self-limiting phenomenon associated with various traumatic events during hard labor such as prolonged labor, episiotomy, instrumental delivery. Close observation of voiding patterns in patients with risk factors is needed to prevent myogenic failure associated with unrecognized asymptomatic post-partum urinary retention.

Here, a case of a 59-year-old man with rotator cuff tear and impingement syndrome caused by an ossified coracoacromial ligament is presented. Ossification of the coracoacromial ligaments can occur because of degenerative changes due to trauma or repeated stress, which can lead to impingement syndrome. Therefore, when coracoacromial ligament ossification is present, rotator cuff damage due to impingement syndrome should be considered. Here, we conducted arthroscopic subacromial decompression, removal of the ossified coracoacromial ligament, and supraspinatus and subscapularis tendon repairs. We achieved satisfactory surgical outcomes without relapse; therefore, we report this case with a literature review.

Calcific tendinitis of the shoulder joint is common disease causing acute pain, mainly involving the supraspinatus or infraspinatus muscle, and less frequently the teres minor or subscapularis muscle. This study reports on the satisfactory arthroscopic removal of calcium deposits as well as infraspinatus and supraspinatus muscle repair without relapse via minimal incision using suture anchors. This was a case of atypically extensive calcific tendinitis involving the infraspinatus muscle, with a bursal side partial rupture of the supraspinatus muscle in a 61-year-old female whose chief complaint was chronic pain of the right shoulder exacerbated by limited movement.

The Parasitological investigation on the encysted metacercariae in brackish water fish, Tribolodon taczanowskii, in the downstream of Hyungsan river which is located in Kyungpook Province of Korea, were carried out serially and the following results were obtained. Metacercariae of Pseudexorchis major were found in six fishes(15.8 per cent ) out of 38 examined. Parasitic frequencies of the encysted metacercaria of Psedexorchis major in Tribolodon taczanowskii were 15.8 per cent (6 out of 38) in the scale, 10.5 per cent (4 out of 38) in the fin, 13.2 per cent (5 out of 38) in the gill, 10.5 per cent (4 out of 38) in the oral cavity and 7.9 per cent (3 out of 38) in the flesh. The worms were identified as Pseudexorchis major (Hasegawa, 1935) Yamaguti, 1938 by morphological studies on the metacercariae, excysted metacercariae, adults and eggs, and compared with prereported Pseudexorchis species.

Journal of the Korean Knee Society 1999;11(1):39-44
The anterior cruciate ligament(ACL) is one of the most important structure for maintenance of the sta- bility of the knee joint. Chronic instability as a result of insufficiency can lead to functional disability, pain, meniscal tears, and degenerative change in articular cartilage. The incidence of injuries of this liga- ment is increasing tendency due to development of vehicle system, industrial system and sports activities. Different authors have recommended both operative and nonoperative treatment for anterior cruciate ligament injuries. Variable methods for functional recovery of anterior cruciate ligament were introduced and argued about ideal method. As arthroscopic techniques improve, surgeons are more inclined to rec- ommend surgical treatment. The methods of repair of acute rupture of the anterior cruciate ligament through the arthrotomy tech- nique have been used widely, but the arthroscopic repair is a relatively new technique. This arthroscopic technique is idealy applicable for rupture at femoral and tibial attachment site. A arthroscopic repair of anterior cruciate ligament was performed with use of the arthroscopy, in 15 consecutive, selected anterior cruciate ligaments that were ruptured at femoral or tibial attachment site, and within 2 weeks after injury. The 15 patients were followed for a minimum of one year(mean, eighteen months; maximum, thirty-eight months). The mean age of the 15 patients at the operation was thirty years(range, seventeen to forty-eight years). The results of arthroscopic repair of anterior cruciate ligament in 15 cases were satisfactory, and as fol- lows. l. All of the 15 cases, the laxity of repaired anterior cruciate ligaments were decreased. 2. The average Lysholm Knee Score Scale was increased from 16 points preoperatively to 89 points postoperatively. Five of the patients(33%) were rated as excellent, and ten patients(67%) were rated as good. 3. The range of motion of the repaired knee joints were from Oo to 135o that results were achieved at postoperative 6 months.
