Accidental or suicidal fatalities of paraquat (Gramoxon) poisong are occasionally seen in the emergency room or intensive care unit in this country. In most cases, respiratory symptoms and eventual death by respiratory distress occur within several days. The most striking pathologic change is fibrosis of the lung due to widespread proliferation of fibroblastic cell. We experience a 21-year-old woman with huge bulla on left lung and diffuse fibrosis in other site, who ingested paraquat 10 months ago. After thoracoscopic removal of bulla, the patient survive without progression of pulmonary complication till now.

BACKGROUND: It has been said that anesthesia and surgery tend to increse 'stress hormone' followed by reduction of GFR and urine flow. We have been noticed a polyuria during mastoidectomy with anesthesia. We hypothesized that a reduction of ADH secretion related to operative procedure might be a cause of a transient polyuria. METHODS: In 41 patients who were in ASA class I, mean arterial pressure (MAP), heart rates (HR), temperature, central venous pressure (CVP) were measured at before induction, just before drilling with irrigation, 30 minutes and 60 minutes after drilling with irrigation, and on arrival in recovery room by groups (room temperatured irrigating fluid and warm fluid were used in group 1 and group 2) during procedures. In 7 of 41, blood samples for antidiuretic hormone (ADH) and plasma osmolalities (Posm) were withdrawn at the same time points. In all patients, fluid were administered with 4 ml/kg/hour throughout the procedures. RESULTS: In group 1, mean urine volume were 5.0 and 6.4 ml/min during anesthesia and drilling with irrigation that was significantly more than in group 2 (3.6 and 4.2 ml/min). In 7 patients, ADH concentration was decreased during surgery compared to pre-induction level, while the Posm were in normal ranges. None of the MAP, HR and CVP showed significant changes. ADH concentrations were not significantly correlated to Posm. CONCLUSIONS: We suggest that a reduction of ADH secretion may have a major role in transient polyuria during mastoidectomy, which might be related to the mechanism that; 1) lowered temperature of hypothalamo-pituitary system by cold irrigating fluid may induce a transient ischemic changes of pituitary gland, 2) absorption of hypoosmolar irrigating fluid to central circulation may reduce central osmotic pressure.

Papillary carcinoma of the thyroid is a well differentiated neoplasm and usually has a good prognosis. However, a subset of morphologically distinct papillary carcinoma has bad prognoses. The tall cell variant of papillary carcinoma (TCPC), characterized by tall columnar cells with a height at least twice the width, is the one of these. In order to differentiate TCPC from usual papillary carcinoma (UPC) in terms of prognosis, we performed immunohistochemical studies for the expression of p53, bcl-2 and Leu-M1 proteins in 25 cases of TCPC, 26 cases of UPC and 14 cases of poorly differentiated, solid type papillary carcinoma (SPC) with an analysis of clinical parameters. The nuclear expression of p53 was noted in one case each of UPC and TCPC. The cytoplasmic p53 expression of TCPC, UPC, and SPC was observed in 17/25 cases (68%), 14/26 cases (54%), 3/14 cases (21%), respectively. bcl-2 expression was 19/25 cases (76%), 18/26 cases (69%), 5/14 cases (36%), and that of Leu-M1 was 21/25 cases (84%), 18/26 cases (69%), 4/14 cases(29%), respectively. There were no statistical significance in the expression of those immunoproteins among these three groups (p>0.05). The p53 protein was consistently expressed in the cytoplasm rather than nucleus in this study and was very well correlated to bcl-2 positivity (p<0.01). There were no statistical significance in any clinical parameters examined among these three groups (p>0.05). In conclusion, TCPC can not be separated from UPC as a distinct entity in this study and the cytoplasmic expression of p53 protein provides another mechanism of p53 inactivation in tumorigenesis of the thyroid papillary carcinoma, possibly by bcl-2 related mechanism.

BACKGROUND: The afferent and efferent pathways of fentanyl cough response (FCR) and central organization are poorly understood at present. The aim of this study was to investigate the pretreatment effects of morphine, propofol, atropine, and midazolam on FCR. METHOD: The 120 healthy patients were randomly assigned to six equal pretreatment groups. They received 2ug/kg fentanyl rapidly through a peripheral venous catheter. The patients in each group were pretreated before the time necessary for peak plasma levels with different drugs as follows: group 1, no premedication; group 2, morphine 0.05 mg/kg iv; group 3, morphine 0.05 mg/kg iv naloxone 0.01mg/kg iv; group 4, propofol 0.5 mg/kg iv; group 5, atropine 0.01 mg/kg iv; group 6, midazolam 0.05 mg/kg iv. The patients were observed for any coughing or side effects, including oxygen desaturation, bronchoconstriction, chest wall rigidity and seizure. RESULT: 40% of patients in group 1 (control) had a cough response to fentanyl. Group 2 (morphine) and group 3 (morphine naloxone) showed a reduced FCR of 10%. The incidence of coughing was 60% of the patients in group 4 (propofol), 30% in group 5 (atropine), and 40% in group 6 (midazolam). These were not statistically significant. CONCLUSION: FCR is not altered by pretreatment with propofol, atropine, or midazolam, but morphine inhibits cough response and this antitussive effect was not antagonized by naloxone.

BACKGROUND: We observed fentanyl known as centrally-acting antitussive agents provoke a cough response in some patients at induction of anesthesia. This may be of clinical importance. METHOD: 121 patients (ASA class I) were assigned randomly to 4 groups. Each group was given different doses of fentanyll Group 1 (n=30); 0.5ug/kg, Group 2 (n=30); 1ug/kg, Group 3 (n=33); 2ug/kg, Group 4 (n=28); 4 g/kgl, within 1 second through a peripheral venous cannula before induction of anesthesia. All patients were observed carefully in order to detect a cough response and any side effects. RESULT: The incidences of FCR (Fentanyl Cough Response) were 0% in Group 1, 10.0% in Group 2, 30.3% in Group 3, and 39.3% in Group 4. The ED50 of FCR was 4.25ug/kg. The mean onset-time from the end of fentanyl administration to the beginning of coughing was 12.5 seconds. FCR was decreased with aging, but not affected by weight, height, or smoking. Other serious side effects were not accompanied. CONCLUSION: Fentanyl can evoke the pulmonary chemoreflex dose-dependently and the ED50 was 4.25 g/kg.

Applied TNM-system for determination and prognostic classification of the cancer patients of Oral and Maxillofacial region does, however, only partly justice, if at all, to the nature of the tumor disease. And the TNM-system implies among other defects a crude simplification of the complex pattern of the tumor disease. But in clinical practice, the prognosis must be determined on the bases of a specific combination of clinical factors under consideration of various therapeutical conditions. For more reliable and objective prognosis determination for the cancer patients of Oral and Maxillofacial region, `Retrospective DOSAK(German-Austrian-Swiss Association for Head and Neck Tumors) study' introduced Treatment-dependent Prognosis Index TPI in 1982. Treatment-dependent Prognosis Index TPI gives the clinician an opportunity to determine the prognosis before starting therapy at the time of the first admission of the patient, during the therapy and immediately after complete of the therapy. The fundamental purpose of the TPI can be summarized as follows. 1) In clinical-therapeutical cancer research the TPI provides a sound basis for the planning and verification of therapy studies. 2) In clinical practice the TPI allows a reliable and objective determination of the prognosis for the individual patient and thus provides the clinician valuable assistance in planning the treatment. The authors estimated the survival curves of the 179 cases of squamous cell carcinoma from 1985.1.1 to 1992.8.31 in the Department of Oral and Maxillofacial Surgery, Seoul National University Hospital according to Treatment-dependent Prognosis Index TPI of Retrospective DOSAK study and compared with the survival curves observed in long term study on prognosis of patients.

Introduction: Anesthesiologists have been aware of the dangers of diffusion hypoxia in the early postoperative period after nitrous oxide anesthesia, but it was suggested of a little clinical significance in healthy patients. Goal of this study is to re-evaluate the possibility of diffusion hypoxia. METHODS: Eighty patients who were scheduled for vitrectomy were allocated to two groups by normal and abnormal chest X-ray findings and each group was divided into two subgroups by N2O concentration (1-a, 2-a; 50%, 1-b, 2-b; 60%). One and half hours after anesthesia, end-tidal alveolar concentration of oxygen (et-O2), N2O (et-N2O), and PaO2 were measured for 10 minutes after the inspired gases were changed to room air 2 L/minute with controlled ventilation in group 1-a. Those parameters were re-measured after re-administration of O2 and N2O of 50% of each for an hour and the inpired gases were changed to room air again. RESULTS: In group 1-a, there was no significant differences of et-N2O and PaO2 after 5 minutes by air flow. And there was no differences of et-N2O and PaO2 between group 1-a and 1-b by et-N2O after 4 minutes. In group 1-b, PaO2 was in normal range at 10 minutes after, although et-O2 was decreased to 14.9%. However, group 2-b showed peripheral arterial saturation lower than 96% after 6 minutes and mild hypoxemia (PaO2 75.3 mmHg) at 10 minutes. CONCLUSIONS: We suggest that hypoxemic episode during spontaneous breathing of room air in early postoperative period after nitrous oxide anesthesia may be occur due to decreased ventilatory function rather than diffusion of nitrous oxide. However, in patients with minimal abnormal chest X-ray findings even without clinical symptoms, it would be better to avoid high concentration of nitrous oxide.

Nausea and vomiting are common problems after strabismus surgery in pediatric patients. We compared the effect of propofol with N2O with the effect of a conventional regimen consisting of halothane - N2O on the occurrence of oculocardiac reflex(OCR), recovery characteristics and the incidence of postoperative emesis after strabismus surgery in 46 ASA physical status I children. After intravenous injection of atropine(0.02 mg/kg), patients were randomly assigned to one of two groups. Group l(conrol) received thiopental, vecuronium, halothane and N2O; Group 2(study), propofol 2 mg/kg and vecuronium bolus followed by infusion of propofol 160 mg/kg/min. Patients in group 2 had more episodes of OCR response than group 1, but had shorter time to recovery from anesthesia(p<0;05). But there was no significant difference in the incidence of postoperative nausea and vomiting between two groups. We conclude that the sufficient doses of propofol only regimen and atropine preadministration(0.02 mg/kg) will be necessary in the strabismus surgery of children for the purposes of the prevention of intraoperative OCR, rapid recovery from anesthesia and reduction of postoperative emesis.

Korean Journal of Anesthesiology 1999;36(3):392-396
BACKGROUND: The monitoring of end-tidal CO2 tension (PETCO2) during high frequency jet ventilation (HFJV) has been unsatisfactory because of a small tidal volume and slow response time of CO2 analyser, although several authors have reported strategies of successful PETCO2 measurement during HFJV. The aim of this study was to assess the validity of tracheal CO2 tension (PtCO2) as a PaCO2 during HFJV. METHODS: We studied 24 patients undergoing laryngomicrosurgery during HFJV (rates: 100/min; I:E= 0.2; driving pressure: 0.25-0.35 MPa) through a 12 Fr. polyethylene injector placed 6-7 cm below the vocal cord. A gas sampling line was placed longitudinally against the injector and they were wrapped with aluminum foil. Continuous capnography was recorded during 20 minutes of HFJV. Every 5 minutes of HFJV, PtCO2 was obtained from the plateau value of CO2 wave after the stopping of JV and arterial blood gas analysis was done at 20 minutes of HFJV comparing PaCO2 to PtCO2. A Pearson's product moment correlation and regression analysis between PtCO2 and PaCO2 and the agreement between the two methods using Bland-Altman method were assessed. RESULTS: A regression analysis (R2=0.928) and a Pearson's product moment correlation (r=0.965, P<0.001) indicated a strong correlation of PtCO2 and PaCO2 during HFJV. The difference against a mean scatter diagram showed a relative good agreement between the two method (mean difference: 1.58 (SD 2.22) mmHg; limit of agreement: 2.86 and -6.02). CONCLUSIONS: PtCO2 obtained from a plateau of CO2 wave on capnography after interruption of HFJV can accurately reflect PaCO2 during HFJV in relative.

A 46-year-old female was admitted to Soon Chun Hyang University hospital with a complaint of intermittent epigastric pain. X-ray and endoscopic pictures showed diffase irregular shallow depression which is similar to the macroscopic pattern of the type IIc early gastric cancer. But endoseopic biopsy showed no malignant cell infiltration. Hndoaeopic biopsy plays an important role in excluding the possibility of carcinoma. But operation shoud be considered inspite of biopsy result because malignant lymphoma ean not be completely ruled out. Histopathologic diagnosis was pseudolymphoma of stomach.
