RESUMO
BACKGROUND: The goal of this study was to evaluate the accuracy and interchangeability between continuous cardiac output (CO) measured by electrical velocimetry (COEv) and continuous cardiac output obtained using the pulmonary thermodilution method (COPAC) during living donor liver transplantation (LDLT). METHOD: Twenty-three patients were enrolled in this prospective observational study. CO was recorded by both two methods and compared at nine specific time points. The data were analyzed using correlation coefficients, Bland-Altman analysis for the percentage errors, and the concordance rate for trend analysis using a four-quadrant plot. RESULTS: In total, 207 paired datasets were recorded during LDLT. CO data were in the range of 2.8-12.7 L/min measured by PAC and 3.4-14.9 L/min derived from the EV machine. The correction coefficient between COPAC and COEv was 0.415 with p < 0.01. The 95% limitation agreement was - 5.9 to 3.4 L/min and the percentage error was 60%. The concordance rate was 56.5%. CONCLUSIONS: The Aesculon™ monitor is not yet interchangeable with continuous thermodilution CO monitoring during LDLT. TRIAL REGISTRATION: The study was approved by the Institutional Review Board of Chang Gung Medical Foundation in Taiwan (registration number: 201600264B0 ).

Ovarian cancer is the second most common cause of death from gynecologic cancer. The aim of this study was to estimate the incidence of ovarian cancer and the trend of mortality in different histological subtypes of ovarian cancer in Taiwan. Patient information regarding ovarian cancer was provided by the Taiwan National Health Insurance database. The histological subtypes of ovarian cancer were retrieved from the Taiwan Cancer Registry database, while the survival rates were extracted from the National Death Registry database. In this population-based cohort study, the annual prevalence, incidence, and overall mortality of ovarian cancer during 2002-2015 were determined. The trend in the incidence and the mortality rate of different histologic subtypes were estimated using joinpoint regression analysis. It was found that age-standardized incidence of ovarian cancer increased from 9.46 in 2002 to 11.92 per 100,000 person-years in 2015, with an average annual percentage change of 2.0 (95% CI = 1.5-2.5). The 1-, 3-, and 5-year mortality rates of overall ovarian cancer declined progressively during the study period, especially the group of Charlson comorbidity index ≤ 1. Ovarian serous carcinoma was the most common histological subtype in Taiwan, comprising 30.9% of ovarian cancer patients in 2002-2015. This study provides valuable information for use in developing healthcare policies for ovarian cancer.
RESUMO
BACKGROUND: Cholecystectomy is one of the most common surgical procedures performed worldwide. The objective of this large, population-based cohort study is to explore the risk factors of pneumonia after cholecystectomy in Taiwan. METHODS: From the Taiwanese National Health Insurance Research Database, we selected all patients who underwent cholecystectomy by using ICD-9-codes, from January 1, 1998, to December 31, 2016. The patients were separated into two groups based on the presence or absence of postoperative pneumonia. Basic information, comorbidities, and postoperative complications were evaluated using a t-test or chi-square test. There were 6056 patients in the pneumonia group and 24224 patients in the control group. These two groups were shown in a ratio of 1 : 4 and were matched by age and sex. The log-rank test was used to examine differences in postoperative mortality between patients with and without pneumonia. Preoperative risk factors were analyzed using logistic regression analysis, after adjusting for age and sex. RESULTS: The final dataset included 282184 cholecystectomy patients. Of these patients, 6056 (2.15%) had postoperative new-onset pneumonia. The patient-related risk factors for pneumonia after cholecystectomy in the order of relevance were chronic obstructive pulmonary disease, congestive heart failure, cerebrovascular disease, diabetes mellitus, surgical type, hemodialysis, coronary artery disease, and liver cirrhosis. Compared to patients without postcholecystectomy pneumonia, those with postcholecystectomy pneumonia had higher rates of mortality (within first month, 1.72% vs. 2.28%, P < 0.005) and admission to intensive care unit (15.02% vs. 41.80%, P < 0.0001) and longer hospital stays (10.71 vs. 18.55 days, P < 0.0001). CONCLUSION: Our results show that postcholecystectomy associated with pneumonia had higher rates of morbidity and mortality in this clinical population. Early identification and possible management of risk factors for pneumonia could improve outcomes of cholecystectomy and lower the risk for patient comorbidities after surgery.

Oxidative stress is an unavoidable event during many complex surgical procedures. 8-iso-prostaglandin F(2alpha) (8-iso-PGF(2alpha)) is a reliable biomarker for the evaluation of oxidative stress in vivo. The aim of this study is to develop simple and accurate liquid chromatography-tandem mass spectrometry (LC-MS/MS) methods for the detection of urinary 8-iso-PGF(2alpha) in samples collected from patients who received a cardiopulmonary bypass (CPB) during cardiac valve surgery. Urine samples of 14 patients with cardiac valve diseases were collected before, during, and after CPB. The level of 8-iso-PGF(2alpha) was detected via selected-reaction monitoring triple quadrupole MS/MS and the result was compared with 12 healthy volunteers. The method's detection limit (3S/N) was 0.25 pg for 8-iso-PGF(2alpha), with a linear working range of 0.25-20 ng/ml. For patients with cardiac valve disease, the 8-iso-PGF(2alpha) levels before the bypasses were the same as those of healthy individuals (P>0.05) and the 8-iso-PGF(2alpha) levels during and after CPB were significantly higher than those before the bypasses (P<0.05). In conclusion, we present a simple and specific protocol for LC-MS/MS quantification of urinary 8-iso-PGF(2alpha) collected during CPB. Using this technique, it would be feasible to assess the levels of oxidative stress during cardiac surgery and thereby helpful for the management of oxidative injury.

Homocystinuria is an autosomal recessive disease with multiple systemic disorders. Here we report a 15-year-old lad suffering from homocystinuria who required an ocular surgery including lentectomy and implant of plastic lens, OS and anterior retinal cryotherapy, OD under general anesthesia because of lens subluxation and lattice degeneration. It is the elective ocular procedure most commonly performed for homocystinuric children. Proper precautions should be taken during anesthetic management since this condition inspires some particular anesthetic complications that could be prevented by careful consideration and understanding of its pathophysiology. Providentially our patient stood the operation well and was discharged without subsequent thromboembolism or other complication as an aftermath.

We retrospectively assessed the computed tomography (CT) features of 31 intrapulmonary lymph nodes (IPLNs) with histopathologic correlations. CT scans revealed that the IPLNs are located in the subpleural region, frequently below the level of the carina, and angular in shape. Most of the IPLNs are solid in texture but occasionally present with a ground-glass appearance. For pleura-attached and pleura-separated IPLNs, one or more and 3 or more linear opacities extending from the nodules can be identified, respectively. Histologically, the IPLNs are located either at the junction of the pleura and lung lobules or at the junction of adjacent lung lobules.

To date, there is no reliable immunohistochemical marker that discriminates between primary pulmonary squamous cell carcinoma (SCC) and cervical SCC metastatic to the lung. In this study, immunohistochemical staining of p16 was performed on 33 primary pulmonary SCCs, 48 primary cervical SCCs, and 17 cases of cervical SCC with pulmonary metastasis. Expression of p16 was noted in 47 cases of cervical SCC (47/48 [98%]), and all were strongly stained. Of the 7 cases of primary pulmonary SCC (7/33 [21%]) in which p16 expression was detected, 3 were weakly positive, 1 was moderately positive, and 3 were strongly positive. Among these p16+ pulmonary SCCs, only 1 showed detectable human papillomavirus DNA. Of the 17 cases of cervical SCC with pulmonary metastasis, all of the pulmonary and cervical tumors were positive for p16. p16 is a useful marker for the discrimination between cervical and pulmonary SCCs. The performance of p16 staining at different cutoff values was also compared.

BACKGROUND: The purpose of this retrospective study was to determine whether epidural fentanyl-bupivacaine patient-controlled analgesia (PCA) was more efficacious and had fewer adverse effects than epidural or intravenous morphine PCA. METHODS: We retrospectively retrieved data from 859 patients (mean age 64+/-7 years) who received continuous epidural medication, either morphine or fentanyl-bupivacaine PCA, or intravenous morphine PCA for postoperative pain control after major elective surgery from 1999 to 2000. Pain was assessed postoperatively using a verbal analogue pain scale (VAS, 0-10) during rest, mobilization, and coughing. Adverse effects including nausea, vomiting, pruritus, urinary retention, sedation, motor block, and respiratory depression (< 8 breaths per minute) were recorded. On the third postoperative day, the overall quality of pain control was evaluated using a pain relief scale (PRS, 1-4). RESULTS: There were 201 patients who had epidural morphine PCA, 427 patients who had fentanyl-bupivacaine PCA, and 231 patients who had intravenous morphine PCA. Most patients (> 86%) who received epidural or intravenous PCA, either morphine or fentanyl combined with bupivacaine, experienced good pain relief (VAS, 0-3) during rest, mobilization, and coughing. Nonetheless, patients who received epidural morphine or fentanyl-bupivacaine had greater satisfaction with overall pain relief (PRS = 4) than did those who received intravenous morphine (p<0.05). Nausea and vomiting were most common in the epidural morphine group (p<0.05). Pruritus occurred least often in patients who received epidural fentanyl-bupivacaine analgesia (p < 0.05). There were no differences in other adverse events such as urinary retention, sedation, and motor block among the three groups. No respiratory depression was found in any patient. CONCLUSIONS: Patients receiving epidural fentanyl-bupivacaine PCA experienced better overall pain relief, while morphine PCA, either epidurally or intravenously, caused more side effects. It is considered safe to use continuous epidural PCA with fentanyl-bupivacaine in patients receiving major elective surgery.

UNLABELLED: We report a case of fatal gas embolism during transurethral incision of the bladder neck under spinal anesthesia in a 76-yr-old man. We confirmed the diagnosis of venous gas embolism by aspiration of frothy blood through the double-lumen central venous catheter and by observation on the transesophageal echocardiogram of a massive gas embolism in the right atrium and right ventricle with obstruction of right ventricle outflow. This report is presented in an attempt to remind anesthesiologists of this unusual but potentially fatal complication that may occur during common transurethral surgery. IMPLICATIONS: We report a patient undergoing transurethral incision of the bladder neck who developed a fatal gas embolism. This report is presented in an attempt to remind anesthesiologists of this unusual but potentially fatal complication that may occur during common transurethral surgery.

PURPOSE: To evaluate if desflurane possesses a shorter wake-up onset time and less incidence of recall than fentanyl-based anesthesia. METHODS: Forty ASA class I-II adolescents, were enrolled into either a desflurane (DES) group, or a fentanyl (FEN) group for scoliosis surgery. Bispectral index (BIS) was monitored continuously in all patients throughout the procedure; the relationship between the wake-up time and BIS value was evaluated. RESULTS: Patients in the DES group had a significantly shorter wake-up onset than patients in the FEN group (4.1 +/- 0.6 vs 8.9 +/- 2.1 min, P < 0.01). No recall occurred during the wake-up test in the DES group, while five patients had recall in the FEN group, including two patients who recalled a given colour. Extubation time was significantly shorter in the DES group than in the FEN group (7.2 +/- 0.6 vs 16 +/- 11.9 min, P < 0.01). BIS values were significantly higher in the FEN group than in the DES group during anesthesia. (62 +/- 4.5 vs 42 +/- 5.3, P < 0.05) BIS after the wake-up test was similar in both groups (90 +/- 2.9 vs 93.8 +/- 2.5). There was a latency period (3.3 +/- 1.2 min) between the maximal BIS value and wake-up time in the FEN group but not in the DES group. CONCLUSIONS: DES provides a significantly shorter onset time during the wake-up test and a rapid emergence after scoliosis surgery. BIS monitoring during the wake-up test was more informative when anesthesia was maintained with DES compared to FEN infusion.
