Background: Hypotension following spinal anesthesia of Cesarean section is mainly caused by peripheral vasodilation and venous pooling due to sympathetic blockade. The degree of sympathetic blockade is known to affect the occurrence of hypotension after spinal anesthesia. The perfusion index (PI) and plethysmographic variability index (PVI) are non-invasive tools for measuring the vasomotor tone and volume status, respectively. The purpose of this study is to compare the trends of PI and PVI values between hypotension and normotension groups during Cesarean section following spinal anesthesia. Methods: Fifty-one parturients were divided into two groups whether they developed hypotension or maintained normotension after spinal anesthesia. Spinal anesthesia was performed with 0.5% hyperbaric bupivacaine (10 mg) and fentanyl (15 μg) at the L3-4 intervertebral space. The data of blood pressure, heart rate, PI and PVI were recorded every minute until delivery of baby. Results: Hypotension occurred in 61% of parturients during Cesarean section. The overall PI and PVI value after spinal anesthesia have gradually increased and decreased, respectively. The degree of increase and decrease in PI (p = 0.31) and PVI value (p = 0.35) was not significant between hypotension and normotension groups. Conclusions The trend of PI value has gradually increased while the PVI value has decreased, regardless of whether the parturient has experienced hypotension or not.

Purpose: : This retrospective study aims to provide basic data for intervention to improve clinical outcomes and identify the characteristics of the rebound hyperthermia (RHG) and non-rebound hyperthermia (NRHG) groups by checking body temperature in patients with post-cardiac arrest syndrome.Method : The study involved 118 patients who completed target temperature management (TTM) in an acute-care unit. Data were analyzed for frequency, percentages, mean, standard deviation, median, and quartiles, and compared using the chi-squared test and Mann–Whitney U-test. Results: : Rebound hyperthermia (RH) was observed in 74 (62.7%) patients, predominantly male (69.5%), with an average age of 64.54 ± 15.98, and a body mass index of 23.22 ± 4.75kg/m2 (overweight). Hypertension (50%) was the most common co-morbidity, followed by diabetes and heart disease (33.1%). Neuron-specific enolase levels were higher in the NRHG 24, 48, and 72 hours after recovery of spontaneous circulation (p = .037, p＜ .001, p= .008). The APHCHE Ⅳ was also higher in the NRHG (p＜ .001). RH occurred 25.49 (7.28–52.96) hours after TTM completion, lasting for 2 (1–3) hours. Temperature reduction strategies included notifying doctors, administering antipyretics, and nursing intervention, with the latter being the most common at 94.6%. Half of the subjects in the RHG and 77.3% in the NRHG fell into cerebral performance categories 3, 4, and 5 (p= .003). Conclusion : RH is more likely a body mechanism related to CPR and TTM than a result of pathogenic infection. Therefore, we require an active intervention for hyperthermia, and a patient-specific nursing intervention protocol.

This study was performed to evaluate the effect of hydrogen peroxide-producing Lactobacillus acidophilus V-2Oonthe replication of periodontal pathogens, Actinobacillus actinomycetemcomitans and Porphyromonas gingivalis. When A. actinomycetemcomitam and P. gingivalis were incubated alone and in the combination with L. acidophilus V-20, the viable cell numbers of A. actinomycetemcomitans and P. gingivalis were compared between those cultures. The effect of S. mutans, E. durans, and L. lactis on the replication of A. actinomycetemcomitans and P. gingivalis was also evaluated. The change of periodontal indexes(probine depth, gingival index, GCF volume) and the viable cell numbers of A. actinomycetemcomitans and black pigmented bdcteroides in subgingival plaque sample were evaluated following gargling of fermented milk made from L. acidophilus V-20 for 1 month on patients with periodontal disease in maintenance phase. In the mixed culture of L. acidophilus V-20 and A. actinomycetemcomitans or P. gingivalis, the replication of A. adinomycetemcomitam or P. gingivalis was completely inhibited. But in the mixed culture of P. gingivalis and hydrogen peroxide-nonproducing Lactobacillus casei, the viable cell numbers of P. gingivalis was not decreased when compared with the numbers in the mixed culture of P. gingivalis and L. acidophilus V-20. In the mixed culture of A. actinomycetemcomitam and S. mutans, E. durans, or L. lactis, the viable cell number of A. adinomycetemcomitans was not almost changed when compared with the numbers in the culture of A. actinomycetemcomitans alone. And in the mixed culture of P. gingivalis and E. durans or L. lactis, the viable cell numbers of P. gingivalis was not almost changed compared with the counts in the culture of P. gingivalis alone. But the replication of P. gingivalis was completely inhibited in the mixed culture of P. gingivalis and S. mutans. When the change of periodontal indexes following gargling of fermented milk was compared with baseline, probing depth and gingival index were not changed, but GCF volume was significantly dcreased(p (0.05). And when the viable cell numbers of microorganisms in subgingival plaque sample were compared with baseline, total viable cell number was almost unchanged and the viable cell numbers of A. actinomycetemcomitans and black pigmented bdcteroides were significantly decreased(p<0.05). These results suggest that L. acidophilus V-20 inhibit the replication of A. actinomycetemcomitans and black pigmented bacteroides by the formation of hydrogen peroxide.

PURPOSE: Cystoscopy is very common and is one of the major office based procedures used in urologic clinics. However, a majority of patients complain of fear, pain, and discomfort when performing the procedure in an alert state. Routine administration of sedative and analgesic drugs is widely provided for gastorintestinal endoscopy to prevent patient discomfort and increase tolerance. Based on this, we investigated the safety and efficacy of midazolam induced sedative cystoscopy. MATERIALS AND METHODS: One hundred and twenty patients were enrolled in this study. They were divided into two groups; group I (n=80) consisted of patients who were sedated by midazolam 2.5mg IV before cystoscopy, and group II (n=40) consisted of patients who were not sedated and diclopenac 90mg was injected in them intramuscularly before cystoscopy to prevent pain. All patients in group I were reversed from the sedative state by flumazenil 0.5mg IV right after the completion of the cystoscopic procedure. The two groups were not significantly different in their age, sex, and weight distribution (p>0.05). Blood pressure, pulse, and respiratory rates were monitored pre-, intra-, and post procedure. The status of consciousness was monitored every three minutes by the OAA/S (Observer's Assessment of Alertness/Sedation) scale. Pain scale, anxiety scale, satisfaction score from patients and operators were measured using a specified questionnaire. RESULTS: In group I, the pain scale and anxiety scale were significantly reduced compared to group II (p<0.001). There were temporary changes in blood pressure and pulse rate in group I, but they were not clinically significant and no specific management was required. Group I patients were significantly more satisfied with their procedures compared to the patients of group II (p<0.001). CONCLUSIONS: Midazolam induced sedative cystoscopy can be applied safely and effectively as an outpatient base procedure. Further, we expect to apply this sedative procedure to other urologic procedures.

Changes in arterial blood gases and arterial pressure during laparoscopic cholecystectomy under the general anesthesia (enflurane in N2O/O2 50%) were investigated in 30 patients, who were divided into two groups according to control of minute ventilation. During surgery, minute ventilation was set 100 ml/kg in group I and 150 ml/kg in group II, and intraabdominal pressure was maintained at 15mmHg by CO2 insufflation, in both groups. Variables were measured before CO2 gas insufflation, 15 and 30 minutes after insufflation, just after exsufflation, 15 and 30 minutes after exsufflation and in recovery room. 1. PaCO2 was increased significantly during CO2 gas insufflation and just after exsufflation in both group, and degree of increase (PaCO2) was significantly greater in group I compared to group II. 2. Changes of PaO2 were not statistically significant in comparison to control value and between two groups during CO2 gas insufflation and exsufflation. 3. Blood pH in both groups were lowered significantly compared to control value during CO2 gas insufflation and exsufflation, and group II (increased minute ventilation group), represents lower risk of acidosis compared to group I. 4. Mean arterial pressure and airway pressure were significantly increased compared to control value during CO2 gas insufflation, but there was no significant difference between two groups. These results suggest that minute ventilation during laparoscopic cholecystectomy should be increased up to maintaining normal PaCO2 for prevention of hemodynamic and blood gas changes due to CO2 retention.

A 44-year-old man was cutting an outer plate of a ship, at a depth of 25 m below sea level. Following a sudden explosion, he was discovered unconscious and was carried to the surface by other divers. There was no evidence of vital signs upon arrival at the hospital. Postmortem computed tomography, which was performed prior to autopsy, revealed massive pneumocephalus in the brain, pneumohemothorax, diffuse lung contusions with multiple traumatic lung cysts, air-fluid level in the cardiac chamber of the chest, and pneumoperitoneum in the abdomen. Postmortem external examination showed a circular abrasion on the jaw, diffuse subcutaneous emphysema, and contusion in the right upper arm. An internal examination revealed intravascular air bubbles in all four chambers of the heart, and diffuse pulmonary trauma including contusion, laceration, and multiple traumatic cysts. Blast injury to the chest, and air embolism due to the underwater explosion were established as the underlying cause of death.

Myoepitheliomas are well-established to occur in the salivary glands, but they have also been described in the breast, upper aerodigestive tract, skin, and soft tissues. We report here on a unique case of primary myoepithelioma that occurred in the right testis of a 28-year-old man. The tumor was entirely confined to the testis and it was clearly separated from the epididymis. Histopathology revealed mixed architectural patterns in which the reticular areas merged into the chondromyxoid stroma. The tumor cells, which were focally immunoreactive to pancytokeratin and S-100 protein, were round to ovoid and spindly arranged in cords, strands, and fascicles. They showed mild nuclear pleomorphism, sparse mitotic figures and a low Ki-67 proliferative index. There was no ductal differentiation in the tumor. To the best of our knowledge, there has been only one case report of a primary testicular myoepithelioma in the English medical literature.

BACKGROUND: Weaning from mechanical ventilation is difficult in the intensive care unit (ICU). Many controversial questions remain unanswered concerning the predictors of weaning failure. This study investigates patient characteristics and delayed weaning after lung transplantation. METHODS: This study retrospectively reviewed the medical records of 17 lung transplantation patients from October 2012 to December 2013. Patients able to be weaned from mechanical ventilation within 8 days after surgery were assigned to an early group (n = 9), and the rest of the patients were assigned to the delayed group (n=8). Patients' intraoperative and postoperative characteristics were collected and analyzed, and conventional weaning predictors, including rapid shallow breathing index (RSBI), were also assessed. RESULTS: The results of the early group showed a significantly shorter ICU stay in addition to a shorter hospitalization overall. Notably, the early group had a higher body mass index (BMI) than the delayed group (20.7 vs. 16.9, p = 0.004). In addition, reopening occurred more frequently in the delayed group (1/9 vs. 5/8, p = 0.05). During spontaneous breathing trials, tidal volume (TV) and arterial oxygen tension were significantly higher in the early group compared to the delayed weaning group, but differences in RSBI and respiratory rate (RR) between groups were not statistically significant. CONCLUSIONS: Low BMI might be associated with delayed ventilator weaning in lung transplantation patients. In addition, instead of the traditional weaning predictors of RSBI and RR, TV might be a better predictor for ventilator weaning after lung transplantation.

BACKGROUND/AIMS: Spontaneous bacterial peritonitis (SBP) is one of critical complications in liver cirrhosis patients with ascites. We aimed to review clinical course of SBP patients in a 10-year period from single center. METHODS: This study enrolled SBP patients between 2005 and 2015. Their medical records were reviewed. The laboratory findings of serum and ascites were examined, and characteristics of isolated microorganisms in ascites were analyzed. RESULTS: Total 51 patients were enrolled. Male patients were predominant (64.7%), and mean age was 59.20 years. The most common etiology of cirrhosis was alcohol (41.2%), followed by hepatitis B (39.2%). Microorganism was isolated from the ascites in 31 patients (60.78%). The proportions of Gram negative and Gram positive were 80.64% and 19.36%. The proportions of Escherichia coli, Klebsiella, and Streptococcus species were 29.41%, 19.61% and 11.76%. Among Escherichia colis, 4 cases were ESBL positive (7.84%). The most commonly used first-line antibiotic was cefotaxime (80.40%). Prophylactic antibiotics treatment was performed only in 8 patients, and SBP was recurred in 7 patients (13.72%). When comparing the SBP recurrence group and the non-recurrence group, there were no significant differences in laboratory findings of serum and ascitic fluid. CONCLUSIONS: SBP is still a critical complication in cirrhosis patients with ascites, and the clinical features of SBP have not been altered much compared with those in 1990's. The effective treatment of SBP is still very important for a better prognosis of cirrhosis patients.
