The proposed factors that affect the prognosis of osteosarcoma are the patient's age, site and size of the primary lesion, pathologic features(type and grade), duration of symptoms, spread of disease (local or regional extension, distant metastasis) at diagnosis, the patient's sex, serum alkaline phos- phatase(ALP) and lactic dehydrogenase(LDH) levels, chromosomal number or DNA index, response to initial chemotherapy, location of the lesion on the bone, presence or absence of pathologic fracture, and mode of therapy. The purpose of this study is to analyze the factors that affect the 5-year survival rates of osteosarcoma. Total 25 patients were included in this study who had treated form Jan. 1988 to Apr. 1994. The overall 5-year survival rate of 25 patients was 65.43%, and the 5-year survival rates were sig- nificantly higher(P < 0.1) in the groups in which limb salvage operation with neoadjuvant chemothera- py were performed(66.67%), with longer duration of symptoms(>2 months; 83.33%), with lower serum level of LDH( < 300 U/L; 100%), and with smaller mass size( < 10cm; 72.92%). However there were no significant differences in the 5-year survival rates according to age and sex of the patients. We also suggest that the better prognosis will be observed in the patients with the favorable radiologic response to the preoperative chemotherapy.

BACKGROUND: To access the accuracy and clinical usefulness of microplate identification (ID) system for the identification of Enterobacteriaceae, we compared microplate ID system with API 20E(bioMerieux, Etoile, France). METHODS: Ninety-two cultures of Enterobacteriaceae and one isolate of Aeromonas species were simultaneously identified by microplate ID system and the API 20E. Twenty biochemical tests used in microplate ID system were lactose, sucrose, and H2S in Kligler's iron agar media; indole, sucrose, raffinose, arabinose, trehalose, adonitol, dulcitol, sorbitol, cellibiose, methy-red, phenylalanine deaminase, ornithine decarboxylase, lysine decarboxylase, arginine dihydrolase, urease, and citrate in microplate; and oxidase test. The identification was obtained by considering percent likelihood(% ID), modal frequency and ID score method. RESULTS: Among the 92 cultures of Enterobacteriaceae and one isolate of Aeromonas species, agreement rate of identification according to the % ID between microplate ID system and API 20E were 90.3% to the species level and 97.8% to the genus level. CONCLUSIONS: For the identification of clinical Enterobacteriaceae isolates, the microplate ID system compares favorably with API 20E in identification accuracy and have the advantage of costsaving and easy to use.

Peritoneal dialysis has been widely considered to be the dialytic treatment of choice for acute renal failure in infants and young children, because the technique is simple, safe and easily adapted for these patients. Also peritoneal dialysis in infants might have more effective ultrafiltration and clearance than in adults. In certain circumstances associated with hemodynamic instability, ordinary volume peritoneal dialysis (30-50 ml/kg body weight per exchange) or hemodialysis may not be suitable unfortunately. But frequent cycled, low volume, high concentration peritoneal dialysis may be more available to manage the acute renal failure of newborns and infants. Seven infants underwent peritoneal dialysis for hemodynamically unstable acute renal failure with low exchange volume (14.2±4.2 ml/kg), short exchange time (30 to 45 minutes) and hypertonic glucose solution (4.25% dextrose). Age was 1.9±1.3 months and body weight was 4.6±1.6 kg. Etiology of acute renal failure was secondary to sepsis with or without shock (5 cases) and postcardiac operation (2 cases). Catheter was inserted percutaneously with pigtail catheter or Tenkhoff catheter by Seldinger method. Dialysate was commercially obtained Peritosol which contained sodium, chloride, potassium, magnesium, lactate and calcium. Net ultrafiltration (ml/min) showed no difference between low volume dialysis and control (0.27±0.09 versus 0.29±0.09). Blood BUN decreased from 95.7±37.5 to 75.7±25.9 mg/dl and blood pH increased from 7.122±0.048 to 7.326±0.063 after 24 hours of peritoneal dialysis. We experienced hyperglycemia which were controlled by insulin (2 episodes), leakage at the exit site (2), mild hyponatremia (1) and Escherichia coli peritonitis (1). Two children of low volume dialysis died despite the treatment. In our experience, low volume and high concentration peritoneal dialysis with frequent exchange may have sufficient ultrafiltration and clearance without significant complications in the certain risked acute renal failure of infants.

BACKGROUND: The Amplified Mycobacterium tuberculosis Direct Test (AMTDT) has been developed for the direct detection of M. tuberculosis complex in respiratory specimens. Traditional methods for diagnosis of extrapulmonary tuberculosis such as the acid-fast bacilli (AFB) stain have their well-known limitations. We investigated the usefulness of the AMTDT for a wide range of non-respiratory specimens to establish early diagnosis of extrapulmonary tuberculosis. METHODS: 346 specimens (219 urine, 117 pleural fluid, 6 ascitic fluid, 2 lymph node, 1 gastric aspirate, and 1 pus specimens) from 340 patients referred from November 1997 to September 1998 were tested by the AMTDT. The AMTDT results were evaluated by comparing with clinical diagnosis and smear results. RESULTS: The overall sensitivity, specificity, and positive and negative predictive values of the AMTDT were 82.9%, 93.8%, 64.2%, and 97.6%, respectively. There were no difference in sensitivity and specificity between pleural fluid and urine specimens. In 31 specimens from tuberculosis patients concurrently tested with AMTDT and stain, 15 were only AMTDT positive and 4 were only stain positive. Among the results considered to be false positive, 47.2% of cases were shown as being less than 150,000 relative light units (RLU). In 30 specimens from tuberculosis patients during or after treatment, all six of the patients with reactivation or aggravation were AMTDT positive, and one case was considered to be false positive. CONCLUSIONS: Our study demonstrates the efficacy of the AMTDT in diagnosing extrapulmonary tuberculosis. Prudent interpretation of the AMTDT's results is recommended in case of that being less than 150,000 RLU.

PURPOSE: This study aimed to investigate visual prognosis and postoperative complications of vitrectomies for macular heterotopia, and compare it with that of tractional macular detachment. METHODS: Medical records of 10 eyes which had undergone pars plana vitrectomy for diabetic macular heterotopia and 21 eyes which for diabetic tractional macular detachment in the 202 patients who had been diagnosed as proliferative diabetic retinopathy at Pusan Paik hospital from January, 1995 to december, 1998 were reviewed to study their clinical features, complications, visual outcome. RESULTS: Final postoperative improved visual acuity was documented in 70% of patients with macular heterotopia and 38% of patients with tractional macular detachment (P>0.05). Postoperative vitreous hemorrhage and cataract developed in 20% and 10% of patients with macular heterotopia and 19% and 10% of patients with tractinal macular detachment. Patients with macular heterotopia experienced retinal detachment and macular hole. Patients with tractional macular detachment experienced increased IOP, neovascular glaucoma and phthisis. CONCLUSIONS: Although we could not revealed statistical significance, the surgical results of vitrectomy for diabetic macular heterotopia was better than that of diabetic tractional macular detachment and in the view of vision and complications, diabetic macular heterotopia was more favorable.

A 71-yr-old male patient with three vessel coronary artery disease underwent a coronary artery bypass graft. The patient was found to have a large pericardial defect at the apex of the heart that measured approximately 18 cm in circumference. The edge of the pericardial defect impinged on the epicardial coronary arteries. The left phrenic nerve descended via the dorsal boundary of the pericardial defect. Following coronary artery bypass grafting, the pericardial defect was repaired with a polytetrafluorethylene patch. The patient had an uncomplicated postoperative course.

Broussonetia papyrifera and Lonicera japonica have long been used in the treatment of inflammatory disorders in Chinese medicine, especially respiratory inflammation. Previously, a new phytoformula (BL) containing B. papyrifera and L. japonica was found to exert strong anti-inflammatory activity against several animal models of inflammation, especially against an animal model of acute bronchitis. In the present investigation, the effects of BL on animal models of septic inflammation and chronic bronchitis are examined. Against lipopolysaccharide (LPS)-induced septic inflammation in mice, BL (200-400 mg/kg) reduced the induction of some important proinflammatory cytokines. At 1 h after LPS treatment, BL was found to considerably inhibit TNF-alpha production when measured by cytokine array. At 3 h after LPS treatment, BL inhibited the induction of several proinflammatory cytokines, including IFN-gamma and IL-1beta, although dexamethasone, which was used as a reference, showed a higher inhibitory action on these biomarkers. Against chronic bronchitis induced by LPS/elastase instillation in rats for 4 weeks, BL (200-400 mg/kg/day) significantly inhibited cell recruitment in bronchoalveolar lavage fluid. Furthermore, BL considerably reduced lung injury, as revealed by histological observation. Taken together, these results indicate that BL may have a potential to treat systemic septic inflammation as well as chronic bronchitis.

Purpose:
To investigate the 5-year outcome of dental implants placed in a grafted maxillary sinus using recombinant human bone morphogenetic protein-2 (rhBMP-2).
Materials and Methods:
We retrospectively analyzed 27 implants after maxillary sinus floor augmentation (MSFA) using rhBMP-2 in 16 patients between January 2016 and March 2017. The study evaluated two outcome variables: (1) 5-year cumulative survival and success rate of the implant after functional loading and (2) marginal bone loss (MBL) for implant failure.
Results:
The average residual bone height was 4.78±1.53 mm. The healing period before loading was 8.35±2.34 months. The crown-to-implant ratio was 1.31±0.26. The 5-year cumulative survival and success rate after functional loading were 100% and 96.3%, respectively. The 5-year average MLB was 0.89±0.82 mm.
Conclusion
Placing dental implants with MSFA using rhBMP-2 is a reliable procedure with favorable long-term survival and success rates.

Lymphocytic hypophysitis, an inflammatory disease of the pituitary gland that is often associated with pregnancy, is caused by autoimmune destruction of the pituitary gland evidenced by diffuse inflammatory cell infiltration of the pituitary gland and some kinds of detectable autoantibodies. We report a case of lymphocytic hypophysitis in a 31-year-old woman presenting with severe hypoglycemia and hyponatremia after delivery. Hormonal study revealed panhypopituitarism and magnetic resonance imaging with enhancement showed the bulging contour of the right side pituitary gland with an ill-defined mass-like lesion and nodular thickening of the stalk. The patient's symptoms and biochemical data improved greatly with replacement of L-thyroxine and glucocorticoid. Partial recovery of panhypopituitarism was also seen. The follow-up tests revealed dramatic resolution of the pituitary lesion.
