Osteochondrodysplasia is a heterogeneous group of disorders appearing short limbed dwarfism. Because many of these entities are lethal and hereditary, an accurate diagnosis is mandatory. The purpose of this study is to define the clinicopathologic features and radiologic findings of osteochondrodysplasia. We reviewed 29 autopsy cases of congenital short limbed dwarfism, consisting of thanatophoric dysplasia (TD) (12 cases), osteogenesis imperfecta (OI) (12 cases), asphyxiating thoracic dysplasia (ATD) (3 cases), short-rib-polydactyly syndrome (SRPS) (1 case) and hypochondrogenesis (1 case). The gestational age ranged from 16 to 41 weeks. Of 6 fetuses that were born alive, 3 were ATD, 2 were TD and 1 was hypochondrogenesis. TD was frequently complicated by hydramnios. Of 8 cases studied chromosomally, only 1 showed chromosomal abnormality -46XY, inv 9. Intrauterine growth retardation was frequently associated with OI. Pulmonary hypoplasia was present in 23 cases (79%), including all cases of ATD, SRPS and hypochondrogenesis, 11 in TD and 7 in OI. Other associated anomalies were present in 17 cases (59%).

OBJECTIVE: To ananlyze the direct effect of nitric oxide (NO), generated from sodium prusside (SNP) on the embryo developments in reproductive process. DESIGN: ova from mouse were treated to allow fertilization in in vitro culture. And the samples of fertilized ova were alloted into five alliqutos. Each alliquot was cultured in media treated with either concentration at 0 (n=92), 25microM (n=84), 50microM (n=80), 100microM (n=77), 500microM (n=54) of SNP. Main Outcome MEASURE: Rates of embryonal cell cleavages, viability and cell morphology were assessed during in vitro fertilization and culture. RESULTS: As analyse the cell cleavage at 24 hours after in vitro culture of fertilised egg in variuos NO concentration, all of egg cells of each alliquot were developed to 2~4 cell stage. But the alliquot of egg cells treated with 500microM, which were totally degenerated. And also all embryonal cells of each alliquot were developed to 8 cell stage and morula stage on culture continuosly. And the embryonal cells of each alliquot were analysed at 24 and 48 hours following the in vitro culture. The rates of cell fragmentation and fusion were 4.2+/-3.4% in control group which is not treated with NO, while experimental groups was high, as rated 23.4+/-6.2% in 25microM, 28.2+/-5.7% in 50microM and 32.1+/-6.4% in 100microM concentration of NO. Accordingly the rate of abnormal morphology of embryonal cell in control was lower significantly than that in each alliquot of experimental groups (p<0.05). And the degenerated rates of embryonal cells were 0% in control, 17.8+/-6.7% in 25microM, 23.6+/-4.7% in 50microM and 26.8+/-11.2% in 100microM at 8 cells and morula on culture of 48 and 72 hours. On the examination of embryonal cells developed to blastocyst through in vitro culture, the rates of degenerated cells were 16.8+/-7.2% in control, 37.5+/-6.2% in 25microM, 73.4+/-4.6% in 50microM, 100% in 100microM. CONCLUSION: This results suggeted that the No in any concentrations is harmful on embryos in view of morphology as well as viability of cell, and the toxicity of No on embryo is stronger at condition in higher concentration of NO.

A 26-year-old man visited our emergency medical center with dyspnea, and he was diagnosed with pulmonary embolism. He did not have any specific risk factor. His job was a computer programming. Pulmonary embolism is rare at such young age. Predisposing risk factors in pulmonary embolism patients include a history of venous thromboembolism, history of malignancy, complicating infections, increasing age, thrombophilia, and obesity. Prolonged seated immobility at work is another risk factor for venous thromboembolism like economy class syndrome. We report a case of pulmonary embolism in a young patient who had no risk factor.

PURPOSE: The optimal chemotherapeutic strategy for gastric cancer patients has not been determined, especially with respect to stage and the curability of gastric cancer. The aim of this study was to evaluate the results of adjuvant chemotherapy on stage IV (T4N1-3M0 and T1-3N3M0) gastric cancer after curative gastrectomy between a chemotherapy (CTX) group and non-chemotherapy (non-CTX) group. MATERIALS AND METHODS: Among 1,760 patients who underwent gastric surgery by 1 surgeon in a single institution, 162 stage IV gastric cancer patients with curative gastrectomy were analyzed retrospectively, excluding patients with TanyNanyM1. One hundred twenty-five patients who received different chemotherapeutic regimens were compared to 37 patients who did not receive chemotherapy for reasons of old age or according to their expressed desire. RESULTS: The clinicopathologic factors which showed a clinically significant difference between the two groups were age and histology, which were not associated with patient survival. The CTX group was younger, and had a larger proportion of undifferentiated gastric cancers than the non-CTX group. The mode of treatment failure revealed no significant difference between the CTX and non-CTX groups. The 1, 3, and 5-year disease-free survival and the 1, 3, and 5-year disease-specific survival of the CTX group were 63.9%, 38.4%, and 32.0%, and 85.4%, 52.3%, and 39.6%, respectively, which were more favorable than the non-CTX group (p=0.015 and p=0.001, respectively). Postoperative adjuvant CTX was an independent risk factor for disease-specific survival of stage IV (T4N1-3M0 and T1-3N3M0) gastric cancer patients after curative gastrectomy by multivariate analysis (odds ratio=2.153; 95% confidence interval=1.349-3.435; p=0.001). CONCLUSIONS: Adjuvant CTX may be associated with survival benefit for younger patients with stage IV (T4N1-3M0 and T1-3N3M0) gastric cancer with undifferentiated histology after curative gastrectomy. A randomized controlled trial to reveal the effect of stage-specific adjuvant chemotherapy should be conducted.

Plasma inorganic fluoride concentrations were measured in adult patients without hepatic or renal disease following sevoflurane-N2O anesthesia (n = 7) or enflurane-N2O anesthesia (n = 6). The anesthetic dosage of sevoflurane and enflurane was 6.48 +/- 2.15 %-hours and 6.57 +/- 2.50 %-hours, respectively. The mean peak plasma inorganic fluoride concentration in the sevoflurane group was 19.5 +/- 13.4 mumol/L 1 hour after anesthesia, which decreased to preanesthetic levels 24 hours after anesthesia. In the enflurane group the values were 13.2 +/- 5.8 mumol/L at the end of anesthesia and decreased, but remained, still twice as high as the preanesthetic level 24 hours after anesthesia. The relationship of plasma inorganic fluoride concentration and anesthetic dosage was more pronounced in the sevoflurane group (r = 0.68, slope = 4.2) than in the enflurane group (r = 0.39, slope = 1.2). In conclusion, sevoflurane-N2O anesthesia results in similar subnephrotoxic levels of plasma inorganic fluoride as enflurane-N2O anesthesia, and although the fluoride concentration had a better correlation to anesthetic dosage in the sevoflurane group than in the enflurane group, its excretion was faster in the sevoflurane group than in the enflurane group.

The use of anesthetic agents may induce a certain number of anaphylactic and anaphylactoid reactions. Anesthesiologists, therefore, are well advised to develop a rational approach to minimize risks and evaluate patients who present with histories of allergic drug reactions in the perioperative period. A 63-year-old female patient was withdrawn from operation due to anaphylactic reaction or life-threatening anaphylactoid reaction occurred during induction of anesthesia and successfully resuscitated. Thereafter, skin prick test to anesthetics including intravenous agents such as thiopental, propofol, ketamine, fentanyl and lidocaine, and muscle relaxants such as succinylcholine, vecuronium and atracurium revealed positive reactions to all the tested muscle relaxants. Next anesthetic experience was done for microvascular decompression surgery without use of muscle relaxants. Two years later, she underwent lumbar laminectomy successfully under isobaric spinal anesthesia using tetracaine.

This study was aimed to evaluate the clinical usefulness of sevaflurane including an adjustability for anesthetic depth and an efficacy in 30 healthy patients who had no previous anesthetic complications or have not experienced general anesthesia within 1 month. After premedication with intramuscular administration of midazolam and glycopyrrolate, anesthesia was induced with thiopental sodium and succinylcholine and endotracheal intubation was done for all the patients. Anesthesia was maintained with 0.5 to 2.0 vol% of sevoflurane according to changes of blood pressure in response to surgical stimuli in N2O(2 L/min)-O2(2 L/min) following 4-5 vo1% inhalation for initial 5 minutes. For the muscle relaxation, vecuronium or pancuronium bromide 0.08 mg/kg was injected initially with additional doses in needed. At the end of operation, administration of N2O and sevoflurane was discontinued. Pure oxygen with 5 L/min- flow rates was inhaled until full recovery. The emergence time interval from the discontinuation of sevoflurane to the response of verbal command was about 10 minutes. The systolic blood pressure during operation reduced by 10 mmHg from preinduction value (from 126 to 116 mmHg). And the heart rate just before incision inereased by 14 beats/min from the preinduction value (from 83 beats/min to 97 beats/min). Arterial blood gas study showed mild hyperventilation with PaCO2 of 30 torr during operation, but PaCO returned normocapneic state during spontaneous breathing after recovery from anesthesia. There was no evidence of respiratory depression during perianesthetic periods. Complete blood counts, biochemical studies, serum electrolytes, and urinalysis at the preanesthetic period, the 1st and 7th postoperative days revealed clinically nonisgnificant changes. However SGPT increased to 30 IU/L in the 7th postoperative day from the preoperative value of 13 IU/L. No arrhythmia did occur during anesthesia, and no complaint including headache, nausea and vomiting ect, was seen after recovery.

PURPOSE: Standard chest compression is useful for cardiopulmonary resuscitation of victims but may be difficult to perform in a confined space if the victim is lying on his side. The aim of this study was to evaluate compression techniques administered to individuals lying in various alternative positions, and to determine which ones may be easier to perform in such situations. METHODS: Thirty two volunteers trained in basic life support (BLS) were enrolled. They were taught to do compression in four alternative positions (over-head position (OHP), saddle position (SP), upper diagonal position (UDP) and lower diagonal position (LDP)). For each position, they performed two minutes of continuous chest compression on a manikin that was connected to a Laerdal PC Skill Reporting System. They did this for the basic standard position (BSP) and four alternative positions with the positions presented randomly. The data, including the total number of compressions, the average rate of chest compressions per minute, the depth of each chest compression, and the position of the hands were recorded and analysed. RESULTS: There were no statistically significant differences between BSP and alternative positions for the total number of compressions (BSP:108.8 min-1; OHP:109.5 min-1; SP:107.8 min-1; UDP:108.5 min-1; LDP:107.7 min-1) of chest compressions. There was no statistically significant difference between BSP and alternative positions for the average depth of each compression (BSP:41.9 mm; OHP:44.4 mm; SP:41.8 mm; UDP:42.9 mm; LDP:41.1 mm), or for the number of incorrect hand positions except UDP (BSP versus UDP = 6.4 versus 32.5). p<0.054 is not normally considered significant. The p value has to be 0.050 or smaller. CONCLUSION: Chest compression in alternative positions can be equally effective as it is in the standard position. If chest compression in the standard position is not easily executable in a confined space, chest compression using an alternative positions can be used.
