BACKGROUND: The purpose of this study was to find out the effect of hypnotics and analgesics on oxygen saturation by pulse oximetry in surgery patients under spinal anesthesia. METHODS: Sixty-five patients classified ASA physical status 1 or 2 scheduled for surgery under spinal anesthesia were studied. These patients were divided into three groups. The 22 subjects of the first group did not receive either midazolam or fentanyl. The 22 subjects of the second group received midazolam. The 21 subjects of the third group received midazolam (0.03 mg/kg) and fentanyl (1.0 microgram/ kg). Oxygen saturation was measured with a pulse oximetry. Measurements were made before spinal anesthesia, 5 minutes, and 10 minutes after starting of spinal anesthesia, 5 minutes, 10 minutes, 30 minutes, and 60 minutes after the start of the operation or intravenous injection of drugs. In addition, measurements were made on arrival in the recovery room, and 5 minutes, 10 minutes, 20 minutes, and 30 minutes after arrival in the recovery room. RESULTS: There were statistically significant differences in oxygen saturation at 5 minutes after the start of the operation or intravenous injection of drugs. The mean oxygen saturation for the first group was 98.2 +/- 1.8%, for the second group 97.9 +/- 2.6%, and for the third group 92.4 +/- 2.8%. Hypoxia cases at 5 minutes after the start of the operation or intravenous injection of a drug occurred in 4.5% of the first group, 9.1% of the second group, and 57.1% of the third group CONCLUSIONS: We concluded that oxygen saturation monitoring should be done routinely in patients receiving hypnotics and analgesics during spinal anesthesia, and oxygen should be administered to patients who develope hypoxia during spinal anesthesia.

There are substantial evidences indiacting that anesthesia and surgery produce significant suppression of immune function. It is generally recognized that immunosuppressive manifestations such as lymphopenia, granulocytosis, decreased transformation to various antigens and impaired neutrophil chemotaxis could be followed by surgical operation. anesthetic agents may also have both direct and hormone-mediated indirect effects on immune systems. Recent evidences indicate that immunosurveillance mechanisms are not only important in the management of emerging infection and malignancy, but also critical to successful elimination of microscopic residual tumor after operation. This study was done to investigate the effeets of halothane anesthesia on T-lymphocyte subpopulations in patients undergoing hysterectomy. Lymphocyte, granulocytes and T-lymphoeyte subpopulations were counted before, during and after anestesia. The results showed that the decrease in the CD4+ cells (helper/inducer T-cells) was bigger than the decrease in the CD8+ cells (suppressor/ cytotoxic T-cells). CD3+ cells (total T-cells) and CD45R+ cells were also decreased. However, these decrease turned to normal values in 5 days. The overall result of this study suggest that anesthesia with halothane may bring temporal suppressive effect on the immunologic responses.

Fatal air embolism can occur during a variety of surgical procedures. We experienced a case of cardiac arrest due to venous air embolism during spinal fusion. A 63-year-old woman underwent spinal fusion for compression fracture on L1 and scolio-kyphosis. Anesthetic induction and initial intraoperative course were completely uneventful until precipitous blood pressure drop occurred, and accompanied by a significant decrease in heart rate and cardiac arrest after use of bone cement. Although more common intraoperative events were presumed and treatment initiated, venous air embolism was considered the etiology of these events when whirring noise was detected by esophageal sthetoscope and a transient decrease in end-tidal carbon dioxide tension was noted by capnometer. We performed cardiac resuscitation with external cardiac compression, various cardiotonic drugs, and removal of air through the right internal jugular venous catheter, but the result was unsuccessful.

BACKGROUND: Several Studies from western institutes were done on the clinical characteristics and long-term prognosis of patients with variant angina. In these reports, 61-92% of patients had significant coronary artery disease, and survival without myocardial infarction at 1 year was approximately 70-83%. These results differ from our clinical experiences with Korean patients with variant angina;however, no detailed study has been reported in Korea. The purpose of this study was to describe the clinical characteristics and long-term follow-up data of our Korean patients with variant angina. METHODS: Two hundred four consecutive patients with variant angina(M/F;166/38, mean age 53+/-10 year) were included. The diagnosis of variant angina was made by spontaneous spasm in 53, positive intravenous ergonovine(iv Erg) provocation in 52, intracoronary acetylcholine(ic Ach) provocation in 55, simultaneous iv Erg and ic Ach provocation in 48 and bedside intravenous ergonovine with 2-dimensional echocardiography in 33. The clinical and angiographic characteristics were examined in 204 patients and mean 1.5 year(6 month to 3.5 year) follow-up could be done in 165 for the evaluation of long-trem prognosis. RESULTS: The Korean patients with variant angina were characterized by relatively low prevalences of significant coronary stenosis(25%), myocardial infarction and rate of cardiac death. Futhermore, survival and survival without myocardial infarction for the entire group were significantly better in our observation(1 year survival without myocardial infarction, 98%) than in other studies. During the follow-up period, 4(2%) out of 165 patients died, 1 developed myocarddial infarction and ventricular fibrillation occurred in 2. Three of 4 death caused by stopping medication abruptly. Thirteen patients were angina free after discontinued medications during the follow-up. CONCLUSION: The overall prognosis of variant angina may be better in Korean patients. We believe that less severe coronary atherosclerotic disease and a high rate of treatment with calcium blockers may have contributed to the lower rate of cardiac death and myocardial infarction on our patients compared with those in previous studies.

Methylmalonic acidemia (MMA) is an autosomal recessive metabolic disease. MMA results from a deficiency of L-methylmalonyl-CoA mutase (encoded by MUT), its cofactor 5-deoxyadenosylcobalamin (MMAA, MMAB, and MMADHC), or a deficiency of methylmalonyl CoA-epimerase (MCEE). We report the case of a 5-day-old infant with MMA in which a missense and a novel nonsense mutation in MUT were present. Direct sequencing analysis of MUT revealed a heterozygous c.1106G>A (p.Arg369His) mutation in exon 6 and a heterozygous c.362_368dupAGTTCTA (p.Tyr123*) mutation in exon 2; the latter results in a premature stop codon.

PURPOSE: Idiopathic granulomatous mastitis is a rare benign inflammatory breast disease of an unknown etiology and the optimal treatment remains controversial. The aim of this study is to evaluate the efficacy of surgically complete excision in patients with idiopathic granulomatous mastitis. METHODS: Between March 2005 and November 2008, we treated 14 cases that were diagnosed with idiopathic granulomatous mastitis. Prospectively, we treated the cases with complete surgical excision with or without steroid therapy in all patients. RESULTS: The mean age of the patients was 36 years (range 30 to 53 years). All cases performed were complete excision with or without steroid therapy. The median follow up period was 26 months (range 5 to 50 months) and all cases had no recurrence. 13 patients out of the 14 were satisfied with the cosmesis of the treated breast. CONCLUSION: We conclude that the treatment of choice for idiopathic granulomatous mastitis is surgically complete excision.

PURPOSE: We analyzed whether any problems existed in terms of the homogeneity of the Korean International Prostate Symptom Score (IPSS) questionnaire used in real practice. MATERIALS AND METHODS: Between July 2012 and August 2012, 48 Korean IPSS questionnaires used in real practice were collected. All the items on the questionnaire, including the quality of life (QoL) questions, were compared and we then determined the homogeneity of each question in comparison with the originally validated Korean version of the IPSS from 1996. RESULTS: Only 5 of 48 sources (10.4%) of the Korean IPSS totally corresponded with the original Korean version of the IPSS questionnaire. The consistency rate with the originally validated version was generally low for the answer choice items for each question, ranging from 16.6% for "less than half the time" to 35.4% for "almost always," with the exception of the item "not at all" (100.0%). The consistency rate was 60.4% for question 3 (intermittency) and 18.8% for question 6 (straining). No homogeneity was found in any of the QoL-related questions. The average consistency rate with the originally validated version was 42.2% and ranged from 22.9% for "unhappy" to the highest rate of 95.8% for "mostly satisfied." CONCLUSIONS: Compared with the originally validated Korean version of the IPSS, various Korean IPSS questionnaires used in real practice had significant problems in terms of homogeneity for both the questions and the answer choice items. Efforts are needed to ensure the uniform use of the validated Korean version of the IPSS questionnaire.

Spontaneously ruptured renal cell carcinoma (RCC) in end-stage kidney disease is very rare. Preoperative diagnosis is difficult because of the relatively small tumor size, associated hematoma, and surrounding acquired cysts. Two middle-aged men who were maintained on hemodialysis (HD) for over 10 years suddenly developed flank pain during HD. Computed tomography scans revealed an enhancing ruptured renal mass in one patient, and no obvious tumor lesion except for a hematoma in the other, both of which were later confirmed as RCCs by pathologic specimens.

PURPOSE: We investigated the prognostic role of volume-based parameters measured on 18F-fluorodeoxyglucose (FDG) positron emission tomography-computed tomography (PET/CT) scans in patients with locally advanced pancreatic cancer (LAPC) treated with chemoradiation therapy (CRT). MATERIALS AND METHODS: We enrolled 60 patients with LAPC who underwent FDG PET/CT before CRT. Maximum standardized uptake value (SUVmax), metabolic tumor volume (MTV), and total lesion glycolysis (TLG) of primary pancreatic cancers were measured on FDG PET/CT scans. Treatment response was evaluated according to the Response Evaluation Criteria in Solid Tumors. Survival analysis was performed using the Kaplan-Meier method, and Cox proportional hazard models were used to determine independent prognostic factors. RESULTS: The progression-free survival (PFS), locoregional progression-free survival (LRFPS), and overall survival (OS) for this population were 6.2, 10.9, and 13.2 months, respectively. The overall treatment response rate was 16.7% at 4 weeks after CRT, and the disease control rate (DCR) was 80.0%. DCR was significantly higher in patients with low SUVmax, MTV, or TLG, and showed strong correlation with longer survival times. On univariate analysis, MTV and TLG were significant prognostic factors for PFS, LRPFS, and OS, together with pre-CRT and post-CRT CA19-9 levels. Multivariate analyses demonstrated that MTV together with the pre-CRT CA19-9 level were independent prognostic factors for PFS, LRPFS, and OS, as was TLG for LRPFS and OS. CONCLUSION: MTV and the pre-CRT CA19-9 level provided independent prognostic information in patients with LAPC treated with CRT. Volume-based PET/CT parameters may be useful in identifying which subgroup of patients would benefit from radiation therapy as a part of CRT.
