Although the incidence is not high in the general surgical population, pulmonary aspiration of gastric contents can result in serious long-term morbidity and mortality. We report a case of early use of extracorporeal membrane oxygenation (ECMO) to correct severe hypoxemia refractory to conventional mechanical ventilation in a patient with massive aspiration of gastric contents immediately followed by acute lung injury during general anesthesia induction. A 64-year-old woman diagnosed with stomach cancer was scheduled for elective diagnostic laparoscopy. Although there was no sign of gastrointestinal tract obstruction and midnight Nil per Os (NPO) was performed before the operation, pulmonary aspiration occurred during the induction of anesthesia. Despite the endotracheal intubation with mechanical ventilation, severe hypoxemia with hypercapnea persisted. Medical team agreed with applying veno-venous (VV) ECMO, and her blood gas analysis results became stable. ECMO was weaned successfully 9 days after the first aspiration event had occurred. Based on this case, early application of extracorporeal life support can have survival benefits.

Background: Inter1eukin-6(IL-6) is known to be produced by osteoblastic cells and to have impartant role in regulation of bone remodelling, Most previous studies indicated that IL-6 bas a major role in stimulating osteoclastic resorption by increasing recruitment and proliferation of preosteoclasts. But its autocrine effect on osteoblastic cells has not been well established yet. Therefore, we studied the effects of IL-6 on messenger RNA (mRNA) expression of proteins that are characteristic of osteoblastic cells in human bone marrow stromal (osteoprogenitor) cells (hRMSC). Methods: The expression of mRNAs for alkaline phosphatase, al(1)-collagen, osteopontin and decorin were studied by northern blot analysis after 3 7 days' treatrnent with IL-6 in the concenttation range of 101,000 U/ml. Results: The mRNA levels for any of the osteoblastic proteins studied did not change significantly by IL-6 treatment up to the concentration of 1,000 U/ml. Conclusion: These results suggest that IL-6 does not have a significant role in differentiatian or activities of human bone rnarrow stromal.

Since the first cases of tsutsugamushi disease reported in Korea in 1986, many cases has been reported and its occurrence has been increasing. Only 2 cases has been reported in Taegu city and Kyungpook area. We experienced an outbreak of 26 cases of tsutsugamushi disease in this area and their clinical manifestations are; 1. The outbreak occurred in September to November in 1988 and its peak occurrence was in October. 2. Mean age was 52 years old (18 to 69 years old) and peak incidence was in the 6th decade. 3. Major symptoms and abnormal signs are fever/chills (88%), myalgia (65%), headache (54%), nausea and vomiting (31%), and abdominal pain (27%). The eschar was detected on lower part of body in most of cases, and more frequently in male (M:F 100 vs 58%). 4. Patients were treated with tetracyclines (TC) and/or chlorampenicol (CM) and mean duration of defervescence from initiation of antibiotic therapy was 2.1days with TC and 2.5 days with CM. 5. Complications are 2 cases of meningitis and 1 case of shock, and all cases were recovered without any sequelae. As above, tsutsugamushi disease occurs in Taegu city and Kyung Pook area as other part of Korea and clinical manifestations are similar to other reports.

PURPOSE: The role of peritoneal washing cytology in determining further treatment strategies after surgery for gastric cancer remains unclear. One reason for this is the fact that optimal procedures to increase the accuracy of predicting peritoneal metastasis have not been established. The aim of this study was to evaluate the efficacy of cytology using samples harvested from two different abdominal cavity sites during gastric cancer surgery. MATERIALS AND METHODS: We prospectively recruited 108 patients who were clinically diagnosed with locally advanced gastric cancer (higher than cT1 stage disease). Peritoneal washing fluids were collected from the pouch of Douglas and the subphrenic area. Patients were prospectively followed up for 2 years to determine the recurrence and survival rates. RESULTS: Thirty-three patients dropped out of the study for various reasons, so 75 patients were included in the final analysis. Seven patients (9.3%) showed positive cytology findings, of whom, three showed peritoneal recurrence. Tumor size was the only factor associated with positive cytology findings (P=0.037). The accuracy and specificity of cytology for predicting peritoneal recurrence were 90.1% and 94.2%, respectively, whereas the sensitivity was 50.0%. The survival rate did not differ between patients with positive cytology findings and those with negative cytology findings (P=0.081). CONCLUSIONS: Peritoneal washing cytology using samples harvested from two different sites in the abdominal cavity was not able to predict peritoneal recurrence or survival in gastric cancer patients. Further studies will be required to determine whether peritoneal washing cytology during gastric cancer surgery is a meaningful procedure.

Of 782 premature babies who had been examed, 105(13.4%) were found to have retinopathy of prematurity(ROP). Between normal group and ROP group, there was statistically significant difference in birth weight, gestational age, duration of oxygen therapy and maximum arterial oxygen concentration. Between the group of regression(stage 1.2 to normal) and the group of progression(stage 1.2 to prethreshold disease) there was statistically significant difference in birth weight, gestational age and the circumferential extent of avascular zone. The 35% of prethreshold ROP eyes progressed to threshold ROP and mean interval from prethreshold to threshold ROP was 3.6 weeks.

The cause of propriospinal myoclonus (PSM) is idiopathic. Cervical trauma, ischemic myelopathy secondary to a spinal dural arteriovenous fistula, syringomyelia, Lyme neuroborreliosis, human immunodeficiency virus central nervous system infection, and cervical disc herniation can be the cause of PSM, but lumbar herniated intervertebral disc (HIVD) induced PSM has not been reported. We describe a patient who presented with PSM induced by HIVD and was treated with an epidural steroid injection using a transforaminal approach.

OBJECTIVES: Rapidly progres s ive glomerulonephritis (RPGN) is a clinico- pathologic entity characterized by extens ive crescent formation(usually involving 50% or more of glomeruli) as the principal his tologic finding and a rapid deterioration of kidney function, which can lead to end s tage renal disease within a few weeks. T he etiology and incidence of RPGN has been well defined in Europe and North America, however, there has been no report of a large series in Korea. T he aim of the present s tudy was to analyze the etiology and clinico- pathologic features of 26 patients with RPGN, seen during 1983-1997. METHODS: T wenty-six patients with RPGN(crescents in > 50% of glomeruli) were obs erved during a period of las t 14 years. Male to female ratio was 1:1.4, and the mean age was 30(6-75) years. Mean time from the initial symptoms to the ESRD was 3.1 months . RESULTS: The incidence of RPGN in our series was 2.1% of primary glomerulonephritis. Immunecomplex mediated disease was presented in 14 cases (54%), including 6 sys temic lupus erythematos us, 3 post- streptococcal glomerulonephritis, 3 Henoch- Schonlein purpura, and 2 IgA nephropathy. Pauci- immune disease was presented in 12 cases (46%), including 3 Wegener' s granulomatos is, one necrotizing crescentic glomerulonephritis, and 8 idiopathic crescentic glomerulonephritis. However, there was none of anti-GBM- mediated disease in our s tudy. ANCA were found in 6 patients. All 3 patients with WG were C- ANCA pos itive, whereas one patient with PSGN, necrotizing cres centic GN, and idiopathic crescentic GN were P- ANCA pos itive, respectively. Initial clinical and laboratory features included edema(80%), hypertens ion(72%), oliguria(68%), a decreased renal function(serum creatinine > 5mg/dL, 35%), and gros s hematuria(36%). Renal biopsy showed large crescents more than 80% of the glomeruli in 14 cases (54%) which were predominantly fibrocellular. Fifteen patients (58%) were treated with prednis olone alone, and 12 of them received puls e doses of corticosteroids. Five patients were treated with prednisolone and cyclophos phamide IV pulse. Two cases received plasma exchange. During the mean follow-up of 31+/-37 months, 18 patients (69%) developed inexorable progression of renal failure, three(12%) showed recovery of renal function, and two(8%) showed partial improvement, which is followed by varying degrees of renal insufficiency. During follow-up, three patients died : two from res piratory failure with severe pulmonary hemorrhage and one from opportunistic pulmonary infection during immunosuppressive therapy. Poor prognos is is as sociated with hypertension, increased serum creatinine level at the time of diagnosis, large crescents more than 85% of glomeruli, and glomerular scleros is . CONCLUSION: We conclude that an earlier diagnos is including kidney biopsy and the more aggressive treatment are essential in the management of RPGN.

Primary stability is a fundamental criteria of implant success. There has been various trials to increase initial stability and bone to implant contact. The objective of osteotome technique is to preserve all the existing bone by minimizing or even eliminating the drilling sequence of the surgical protocol. The bone layer adjacent to the osteotomy site is progressively compacted with various bone condensers(osteotomes) this will result in a denser bone to implant contact. This improved bone density helps to optimize primary implant stability in low density bone. The use of wide implant is one of methods to increse primary stability. They can be used in special situations in which they can increase the surface area available for implant anchorage and improve their primary stability The aim of this study was to evaluate the influence of the osteotome technique and implant width on primary stability. Osteotome technique was compared with conventional drilling method by resonance frequency measurments according to the implant fixtures diameter. The results were as follows: 1. The average of ISQ value was sightly higher in osteotome technique, but there was not statistically significant in regular and narrow implant(p<0.05). 2. Either osteotome technique or conventional technique, ISQ value was significantly higer as increasing of implant diameter(p<0.05). 3. ISQ value of drilling technique was higer than those of osteotome technique in wide implant. It was assumed to be caused by difference in final preparation diameter.
