Arthroscopic synovectomy has some limitations for adequate posterior visualization, and it is difficult to establish the posterior portal because of potential damage to neurovascular structures. The purpose of this study is to introduce a newly designed arthroscopic technique passing through posterior septum and to review the arthroscopic synovectomy using transposterior septal portal in the knee. Routine arthroscopic examination of the knee joint is performed using standard anterolateral and anteromedial portals. Posterior arthroscopic technique is divided into four steps. The first step is to make a posteromedial portal. The second step is to make a posterolateral portal. The third step is to make a hole at the posterior septum and to examine the posterolateral compartment. The fourth step is to examine the posteromedial compartment by switching the arthroscope to the posterolateral portal in the same manner. This technique provides complete visualization of the posterior compartment of the knee joint including the posterior aspect of the medial and lateral femoral condyles, posterior horn of both menisci, the posterior cruciate ligament(PCL), the meniscofemoral ligament, posterior aspect of the popliteal tendon, and the posterior capsule. We reviewed 47 cases(of 43 patients) of arthroscopic synovectomy using anterolateral, anteromedial and transposterior septal portal. The results were assessed with follow up of at least 1 year using the criteria of pain, synovitis, effusion, and range of motion. In 15 case rheumatoid arthritis, we had good result in 14 cases, but 1 case of recurrence was noted at 2 months after surgery. Non specific synovitis, 11 cases, had the similar result of rheumatoid arthritis. In 9 cases with hemophilic arthritis, pain and effusion were improved, but range of motion was improved minimally. In 2 cases with gouty arthritis, 2 cases with tuberculous arthritis, and I case with pigmented villonodular synovitis(PVNS), range of motion was rather reduced. It is considered that arthroscopic technique using transposterior septal portal is safe procedure without damaging the PCL, posterior capsule, neurovascular structures, and very efficient method in removing hypertrophied synovium or debris of persistent synovitis or arthritis of the knee joint and helpful in removing encapsulated loose bodies located behind the PCL.

We have employed the external akeletal fixation devices, that is Hoffmann apparatus and Pin and Resin fixation method, for the treatment of 44 cases of long bone fractures from Dec. 1978 to Dec. 1981. The following are our impressins. 1. Hoffmann apparatus and Pin and Resin fixation method proved to be effective and useful measure for the management of fractures of long bones, particulary in cases of the open tibial fractures. 2. Employing the Hoffmann apparatus to the tibial model, the possible limit of correction of the fracture alignment was calculated. It was found that the average angle of correction of deformity can be managed up to 20 degrees in varus and valgus deformity, 70 degrees in anterior angulation, 40 degrees in posterior angulation and 70 degrees in rotation. 3. Pin and Resin fixation method is one of effective means in immobilization of long bones. It is simple to apply, easy to manipulate and inexpensive while offering fair fixation without much complications and therefore we recommend the method as the best alternative to expensive Hoffmann apparatus. 4. The complications of Hoffmann apparatus and Pin and Resin fixation method were pin tract infections and ankle stiffness which were generally minor and prevented by more careful aseptic technique and encouraging early joint motion.

OBJECTIVE: To determine whether the somatostain analogue, octreotide, pretreatment before ovulation induction with human menopausal gonadotropin (hMG) affects ovarian response, and ovulation induction outcome in infertile patients with polycystic ovarian syndrome (PCOS) resistant to clomiphene citrate (CC) METHODS: From November 1998 to June 1999, 30 infertile patients with PCOS unresponsive to CC were randomly allocated either octreotide pretreatment (treatment group) (n = 15) or hMG alone (control group) (n = 15) groups. In the treatment group, 100 g of octreotide were administered daily for 7 days after progesterone injection for withdrawal bleeding, and then hMG was administered for ovulation induction. RESULTS: There were no differences in the total number of hMG ampules required and the duration of hMG administration between the two groups. The number of follicles of 10-14 mm diameter on the day of hCG injection was significantly less in the treatment group than that in the control group (4.3 +/- 2.5 vs. 9.6 +/- 4.4, p < 0.001). The serum estradiol (E2) level on the day of hCG injection was significantly lower in the treatment group, with 1579.2 +/- 421.0 pg/ml compared with 2120.3 +/- 512.7 pg/ml in the control group (p < 0.001). The hematocrit level on the day of hCG injection was also significantly lower in the treatment group than that in the control group (36.9 +/- 2.1% vs. 40.8 +/- 2.9%, p < 0.05). The incidence of severe ovarian hyperstimulation syndrome (OHSS) seemed to be lower in the treatment group, but the difference did not achieve significance (6.7% vs 20.0%). CONCLUSION: This study suggests that octreotide pretreatment before ovulation induction could improve hormonal milieu compared to hMG alone, and therefore may be effective in ovulation induction for patients with PCOS resistant to CC.

Investigations into the development of new therapeutic agents for lung inflammatory disorders have led to the discovery of plant-based alternatives. The rhizomes of Anemarrhena asphodeloides have a long history of use against lung inflammatory disorders in traditional herbal medicine. However, the therapeutic potential of this plant material in animal models of lung inflammation has yet to be evaluated. In the present study, we prepared the alcoholic extract and derived the saponin-enriched fraction from the rhizomes of A. asphodeloides and isolated timosaponin A-III, a major constituent. Lung inflammation was induced by intranasal administration of lipopolysaccharide (LPS) to mice, representing an animal model of acute lung injury (ALI). The alcoholic extract (50–200 mg/kg) inhibited the development of ALI. Especially, the oral administration of the saponin-enriched fraction (10–50 mg/kg) potently inhibited the lung inflammatory index. It reduced the total number of inflammatory cells in the bronchoalveolar lavage fluid (BALF). Histological changes in alveolar wall thickness and the number of infiltrated cells of the lung tissue also indicated that the saponin-enriched fraction strongly inhibited lung inflammation. Most importantly, the oral administration of timosaponin A-III at 25–50 mg/kg significantly inhibited the inflammatory markers observed in LPS-induced ALI mice. All these findings, for the first time, provide evidence supporting the effectiveness of A. asphodeloides and its major constituent, timosaponin A-III, in alleviating lung inflammation.

OBJECTIVE: To compare the usefulness of magnetic resonance cholangiopancreatography (MRCP) and MR angiography (MRA) in differentiating malignant from benign intraductal papillary mucinous tumors of the pancreas (IPMTs), and to determine the findings which suggest malignancy. MATERIALS AND METHODS: During a 6-year period, 46 patients with IPMT underwent MRCP. Morphologically, tumor type was classified as main duct, branch duct, or combined. The diameter of the main pancreatic duct (MPD), the extent of the dilated MPD, and the location and size of the cystic lesion, septum, and communicating channel were assessed. For all types of IPMTs, enhanced mural nodules and portal vein narrowing were evaluated at MRA. RESULTS: Combined-type IPMTs were more frequently malignant (78%) than benign (42%) (p < 0.05). Compared with benign lesions, malignant lesions were larger, and the caliber of the communicating channel was also larger (p < 0.05). Their dilated MPD was more extensive and of greater diameter (p < 0.05), and the presence of mural nodules was more frequent (p < 0.001). CONCLUSION: Combined MRCP and MRA might be useful for the differential diagnosis of malignant and benign IPMTs of the pancreas.

We report a rare case of primary tracheal malignent melanoma documented by careful clinical examination. Differentiation between primary and metastatic malignant melanoma is very difficult. We conclude that this tracheal tumor is a primary malignant melanoma based on characteristic pathologic features and the exclusion of the possibility of spontaneous regression of the primary site by patient's history and physical examination.

PURPOSE: We evaluated the characteristics of and treatment outcomes in patients with benign tracheobronchial tumors. MATERIALS AND METHODS: We reviewed the records of patients with benign tracheobronchial tumors who underwent bronchoscopic intervention with mechanical removal and Nd: YAG laser cauterization, and evaluated the characteristics and treatment outcomes of 55 patients with hamartomas, leiomyomas, papillomas, typical carcinoids, or schwannomas seen between April 1999 and July 2012. RESULTS: The most common tumors were hamartoma (n=24), leiomyoma (n=16), papilloma (n=7), typical carcinoid (n=5), and schwannoma (n=3). Forty-one patients (75%) had symptoms. On chest computed tomography, 35 patients (64%) had round or ovoid lesions, accompanied by atelectasis (n=26, 47%) or obstructive pneumonia (n=17, 31%). Fatty components (n=9, 16%) and calcifications (n=7, 13%) were observed only in hamartomas, leiomyomas, and typical carcinoids. At bronchoscopy, the typical findings were categorized according to tumor shape, surface, color, and visible vessels. Fifty (91%) patients underwent complete resection. Forty patients (73%) achieved successful bronchoscopic removal defined as complete resection without complications or recurrence. Recurrences occurred in four papillomas, one leiomyoma, and one typical carcinoid. The proportions of tumor types (p=0.029) differed between the successful and unsuccessful removal groups, and a pedunculated base (p<0.001) and no spontaneous bleeding (p=0.037) were more frequent in the successful removal group. CONCLUSION: We described clinical, radiological, and typical bronchoscopic findings in patients with benign tracheobronchial tumors; these findings might help to differentiate such tumors. Bronchoscopic intervention was a useful treatment modality, and tumor type, pedunculated base, and vascularity may influence successful tumor removal.
