ABSTRACT

Objective: To explore the quality of life and its influencing factors of enhanced recovery after surgery (ERAS) of esophageal cancer patients. Methods: The quality of life of 134 esophageal cancer patients was assessed using the quality of life assessment scale (EORTC QLQ-C30) developed by the European Cancer Research and Treatment Organization. Student's t test, One-way ANOVA and multiple linear regression statistical methods were used to analyze the effects of sociodemographic and clinical characteristics on patients' quality of life. Results: The overall score of quality of life (74.00) was lower than that of the general population (75.30). However, the scores of emotion and cognition in function dimension (93.97 and 95.77) were better than those of the general population (82.80 and 86.50). The results of fatigue, pain, insomnia and constipation in symptom dimension (14.18, 10.94, 11.69 and 5.72) were better than those of the general population (28.80, 20.50, 20.40 and 10.70). The pathological stage, body mass index and dietary were independent influencing factors for the quality of life of patients with esophageal cancer (P<0.05). Conclusions: ERAS can partially improve the quality of life of esophageal cancer patients. More attention should be paid to the esophageal cancer patients after surgery and take targeted measures to improve their quality of life.

ABSTRACT

BACKGROUND: Construction of animal models of vertebral artery type of cervical spondylosis and evaluation have become a new issue of concern.OBJECTIVE: To describe the research progress of animal models of vertebral artery type of cervical spondylosis at home and abroad, and to evaluate the advantages and disadvantages of each method. METHODS: The keywords were "cervical vertigo, basal-vertebral ischemia, cervical spondylosis of vertebral artery type, animal, model" in Chinese and English, respectively. CNKI, WanFang, VIP, PubMed, Cochrane Library, and Embase databases were retrieved for the articles published from 1998 to 2018. Chinese and English articles on animal modeling of vertebral artery type of cervical spondylosis were selected according to the inclusion and exclusion diagnosis criteria of vertebral artery type of cervical spondylosis. RESULTS AND CONCLUSION: Through induction and analysis, modeling methods include hardener injection, bone graft compression, dynamic imbalance, blood stasis blocking collaturation, vertebral artery ligation and mixed modeling method. Of them, hardener injection method is most commonly used. Bone graft compression method is the most similar pathogenesis to the human body. However, the disadvantage is that the modeling is difficult and the size of the bone block is various. So the bone is not in the right position. Dynamic imbalance method can cause cervical spine imbalanced by resecting the unilateral muscle and bone. This method has high operability, but has long modeling period. Although ligating or clipping the unilateral vertebral artery is easy to operate, the pathogenesis of vertebral artery type of cervical spondylosis is not just vertebral artery stenosis, which ignores the influence of humoral factors, sympathetic nerves and vertebral nerves on the blood flow velocity and lumen size of vertebral artery. Each method has advantages and disadvantages. The evaluation criteria, time and success rate are different.

ABSTRACT

Objective How to improve the operational safety of foraminoplasty has become a hot spot in present clinical research. This study was to observe the clinical effect of minimally invasive treatment of lumbar disc herniation by percutaneous transforaminal endoscopic discectomy (PTED) combined with dynamically assisted visualized intervertebral foraminoplasty (VIVF).Methods Totally, 61 patients with lumbar disc herniation underwent PTED combined with dynamically assisted VIVF in Jiangsu Provincial Hospital of Integrated Traditional Chinese and Western Medicine from January to November 2017. We evaluated the clinical effects using the Visual Analogue Scale (VAS), Oswestry Disability Index (ODI) and modified Macnab Criteria.Results The VAS scores of the patients were significantly lower at 3 days, 3 months and 6 months after surgery than the baseline (1.10±0.60, 1.03±0.26 and 1.07±0.31 vs 7.64±1.11, P<0.05), and so were the ODIs (2.10±0.54, 1.30±0.49 and 1.23±0.46 vs 34.46±3.57, P<0.05). The excellence rate of treatment 96.72% (59/61). None of the patients experienced such postoperative complications as nerve root injury, spinal injury, and dural matter, and no recurrence was observed.Conclusion PTED combined with dynamically assisted VIVF is safe and effective for the treatment of lumbar disc herniation.

ABSTRACT

BACKGROUND: A disputed rpoB mutation is a specific type of rpoB mutation that can cause low-level resistances to rifampin (RIF). Here, we aimed to assess the frequency and types of disputed rpoB mutations in Mycobacterium tuberculosis isolates from South Korea. METHODS: Between August 2009 and December 2015, 130 patients exhibited RIF resistance on the MTBDRplus assay at Asan Medical Center. Among these cases, we identified the strains with disputed rpoB mutation by rpoB sequencing analysis, as well as among the M. tuberculosis strains from the International Tuberculosis Research Center (ITRC). RESULTS: Among our cases, disputed rpoB mutations led to RIF resistance in at least 6.9% (9/130) of the strains that also exhibited RIF resistance on the MTBDRplus assay. Moreover, at the ITRC, sequencing of the rpoB gene of 170 strains with the rpoB mutation indicated that 23 strains (13.5%) had the disputed mutations. By combining the findings from the 32 strains from our center and the ITRC, we identified the type of disputed rpoB mutation as follows: CTG511CCG (L511P, n=8), GAC516TAC (D516Y, n=8), CTG533CCG (L533P, n=8), CAC526CTC (H526L, n=4), CAC526AAC (H526N, n=3), and ATG515GTG (M515V, n=1). CONCLUSION: Disputed rpoB mutations do not seem to be rare among the strains exhibiting RIF resistance in South Korea.

ABSTRACT

BACKGROUND/AIMS: While surgical resection remains the standard of care in the treatment of upper urinary tract malignancies, nephrectomy is a risk factor for the development of chronic kidney disease (CKD). The aim of this study was to determine whether histologic evaluation of non-neoplastic kidney could enable early identification of unrecognized kidney disease and could be of prognostic value in predicting postoperative renal outcomes. METHODS: We retrospectively analyzed 51 patients with upper urinary tract malignancies who received uninephrectomy or uninephroureterectomy. A thorough pathologic evaluation of non-neoplastic kidney including special stains, immunofluorescence, and electron microscopic studies was performed. The degree of parenchymal changes was graded from 0 to 15. RESULTS: Of 51 patients, only 13 showed normal kidney pathology. Fifteen patients showed glomerular abnormalities, 14 showed diabetic nephropathy, and 11 showed vascular nephropathy. There was one case each of reflux nephropathy and chronic pyelonephritis. The median histologic score was 5 points. Only 25.4% of patients had ≤ 3 points. Score more than 5 was observed in 47.1% of patients. Postoperative estimated glomerular filtration rate (eGFR) at 3 to 36 months were obtained from 90.2% of patients, and of those, 34.8% had de novo CKD. Since no one had CKD in partial nephrectomized patients, we determined risk factors for CKD in radical nephrectomized patients. Cox regression analysis revealed that postoperative AKI, preoperative eGFR, and histologic score of non-neoplastic kidney were the independent predictors for CKD. CONCLUSIONS: We conclude that routine pathologic evaluation of non-neoplastic kidney provides valuable diagnostic and prognostic information.

ABSTRACT

Objective To investigate the modified method of intracavernous cannulation in monitoring intracavernous pressure (ICP) of rats.Methods The present study was conducted from October to December 2014.Twenty male Sprague-Dawley rats were randomly divided into 2 groups,the conventional group (cannulated in the crus of the penis) and the modified group (cannulated in the corporal body of the penis).The erectile function of the rats was assessed by measuring ICP/MAP (mean arterial pressure) ratio.The electrical-stimulation (ES) parameters were 5 V,15 Hz,5 ms,and 60 s for each stimulation.Results The differences in the basic ICP (14.9 ± 2.7 versus 15.5 ± 3.1 mmHg),ES-ICP (87.6 ± 7.5 versus 85.0 ± 6.2 mmHg),and ICP/MAP (71.3% ± 6.6% versus 72.5% ± 6.3%) were not significant between the 2 groups (P >0.05 for all).Compared with the conventional group,the modified group could accurately cannulate the corpus cavernosum under direct vision,with an improved successful rate (100% versus 80%),but there was no significant difference (P > 0.05) in intracavernous pressure measurement.Conclusion The modified method of cannulating in the corpus cavernosum could have the advantage of higher successful rate,suggesting a feasible way for basic research of erectile dysfunction in rats.

ABSTRACT

BACKGROUND/AIMS: Increased arterial stiffness is a well-known risk factor for cardiovascular disease. Cilostazol, a phosphodiesterase type 3 inhibitor, is a unique antiplatelet agent with vasodilatory and vasoprotective effects. Therefore, we hypothesized that cilostazol may affect arterial stiffness. METHODS: We enrolled 161 patients (112 males; mean age, 63 years) who had undergone percutaneous coronary intervention (PCI) for ischemic heart disease. The brachial-ankle pulse wave velocity (baPWV), radial augmentation index (rAI), rAI adjusted for a heart rate of 75 beats/min (rAI75), central systolic blood pressure (cSBP), and central pulse pressure (cPP), were measured at baseline and at the 30-day follow-up. Parameter changes were compared between the cilostazol group (n = 51) and the control group (n = 110). RESULTS: In the cilostazol group, the values for rAI, cSBP, and cPP all improved after 30 days, while the control group displayed no significant interval changes in these parameters. The changes in rAI75 and baPWV did not differ significantly between the two groups. The changes in rAI, cSBP, and cPP were related to brachial systolic blood pressure, brachial diastolic blood pressure, heart rate, and the use of cilostazol and beta-blockers. In a multivariate analysis, the use of cilostazol was identified an independent factor associated with changes in rAI, cSBP, and cPP. CONCLUSIONS: The addition of cilostazol to conventional antiplatelet therapy in patients undergoing PCI may be associated with improvements in rAI, cSBP, and cPP, but not in rAI75 or baPWV. Therefore, the effects of cilostazol might be related to an increased heart rate.

ABSTRACT

PURPOSE: Sedatives must be carefully titrated for patients with obstructive sleep apnea-hypopnea syndrome (OSAHS) as oversedation may lead to disastrous respiratory outcomes. This study aimed to investigate the relations between the effect-site concentration (Ce) of propofol and sedation and airway obstruction levels in patients with OSAHS. MATERIALS AND METHODS: In 25 patients with OSAHS, sedation was induced by 2% propofol using target-controlled infusion. Sedation and airway obstruction levels were assessed using the Observer's Assessment of Alertness/Sedation Scale and a four-category scale, respectively. The relationships between propofol Ce and sedation and airway obstruction were evaluated using a sigmoid Emax model. Pharmacodynamic modeling incorporating covariates was performed using the Nonlinear Mixed Effects Modeling VII software. RESULTS: Increased propofol Ce correlated with the depth of sedation and the severity of airway obstruction. Predicted Ce50(m) (Ce associated with 50% probability of an effect> or =m) for sedation scores (m> or =2, 3, 4, and 5) and airway-obstruction scores (m> or =2, 3, and 4) were 1.61, 1.78, 1.91, and 2.17 microg/mL and 1.53, 1.64, and 2.09 microg/mL, respectively. Including the apnea-hypopnea index (AHI) as a covariate in the analysis of Ce50(4) for airway obstruction significantly improved the performance of the basic model (p<0.05). CONCLUSION: The probability of each sedation and airway obstruction score was properly described using a sigmoid Emax model with a narrow therapeutic range of propofol Ce in OSAHS patients. Patients with high AHI values need close monitoring to ensure that airway patency is maintained during propofol sedation.

ABSTRACT

Young radish (Raphanus sativus L), a member of the mustard family (Cruciferae), is a common ingredient of Kimchi. Although few reports have described anaphylaxis to cruciferous vegetables, we report the case of anaphylaxis induced by contact with young radish. A 46-year-old female with a history of contact allergy to metal presented to our emergency room (ER) with dizziness, generalized eruption and gastrointestinal upset. Her symptoms developed after re-exposure to young radish while chopping it. Hypotensive blood pressures were noted. Three days prior, the patient had experienced generalized urticaria with pruritus immediately after chopping the fresh young radish, which resolved spontaneously. In the ER, her symptoms improved by the administration of epinephrine (0.3 mL), antihistamine (chlorpheniramine) and isotonic saline hydration. A skin prick test with young radish extract showed positive reactivity. The same skin test was negative in five adult controls. IgE-mediated hypersensitivity could be an important immunologic mechanism in the development of young radish-induced anaphylaxis.

ABSTRACT

BACKGROUND/AIMS: To date, high-resolution manometry has been used mainly in the study of esophageal motility disorders and has been shown to provide more physiological information than conventional manometry, and is easier to interpret. This study aimed to evaluate the usefulness of high-resolution anorectal manometry (HRARM) compared to water-perfused anorectal manometry. METHODS: Patients who complained of chronic constipation with/without fecal incontinence underwent both water-perfused anorectal manometry and HRARM in a random order on the same day. Resting and squeezing pressures of the anal sphincter, attempted defecation, rectoanal inhibitory reflex, rectoanal contractile reflex, Rao's type of dyssynergia during attempted defecation, anal canal length, defecation dynamic parameters and measurement times for each method were analyzed. RESULTS: Of 14 patients, 7 were female, and the median age was 59 years (range 35-77). Indications for manometry were constipation (n = 8) and constipation with fecal incontinence (n = 6). Resting and squeezing pressures showed that the 2 methods were strongly correlated (resting pressure: r = 0.746, P = 0.002; squeezing pressure: r = 0.921, P < 0.001). In attempted defection, one equivocal case with water-perfused anorectal manometry was diagnosed type I pelvic floor dyssynergia with HRARM providing detailed pressure changes in internal and external anal spincters, and puborectalis muscle which improved assessment of anorectal disorders. The measurement time for HRARM was significantly shorter than that for water-perfused anorectal manometry (11.3 vs 23.0 minutes, P < 0.001). CONCLUSIONS: Both water-perfused anorectal manometry and HRARM are well tolerated and reliable methods of evaluating defecation disorders of pelvic floor dysfunction. HRARM is likely to provide better physiological information and to require a shorter measurement time compared to water-perfused anorectal manometry.

ABSTRACT

A 46-year-old male arrived at the emergency department with acute dyspnea. On the way to the hospital, heart massage was performed in the ambulance due to asystole on electrocardiography. After 2 hr of resuscitation, sinus rhythm was restored. Extracorporeal life support and an intra-aortic balloon pump were applied due to cardiogenic shock, but the patient showed sustained hypotension. Echocardiography showed moderate pericardial effusion with physiological evidence of cardiac tamponade; emergency pericardiocentesis was performed, which produced bloody pericardial fluid. An explorative sternotomy revealed a massive hematoma in the mediastinum and right ventricular (RV) free wall rupture. After primary repair, echocardiography showed improved left ventricular systolic function and the patient was stable clinically. This case presents RV free wall rupture as an unusual complication of prolonged heart massage. Heart rupture should be considered in hemodynamically unstable patients after prolonged heart massage.

ABSTRACT

BACKGROUND: Bronchiectasis and asthma are different in many respects, but some patients have both conditions. Studies assessing the effect of bronchiectasis on asthma exacerbation are rare. The aim of this study is to investigate the effect of bronchiectasis on asthma exacerbation. METHODS: We enrolled 2,270 asthma patients who were followed up in our hospital. Fifty patients had bronchiectasis and asthma. We selected fifty age- and sex-matched controls from the 2,220 asthma patients without bronchiectasis, and assessed asthma exacerbation and its severity based on the annual incidence of total asthma exacerbation, annual prevalence of steroid use, and frequency of emergency room visits and hospitalizations due to asthma exacerbation in each group. RESULTS: Fifty patients (2.2%) had bronchiectasis and asthma. The annual incidence of asthma exacerbation was higher in patients with asthma and bronchiectasis than in patients with asthma alone (1.08+/-1.68 vs. 0.35+/-0.42, p=0.004). The annual prevalence of steroid use (0.9+/-1.54 vs. 0.26+/-0.36, p=0.006) and the frequency of emergency room visits (0.46+/-0.84 vs. 0.02+/-0.13, p=0.001) due to asthma exacerbation were also higher in patients with asthma and bronchiectasis than in patients with asthma alone. CONCLUSION: Bronchiectasis is associated with difficult asthma control.

ABSTRACT

PURPOSE: Emergence agitation (EA) is frequently observed in children undergoing general anaesthesia. This study tested whether the addition of an intra-operative low-dose infusion of dexmedetomidine to fentanyl treatment reduced the incidence of emergence delirium following desflurane anesthesia in children undergoing strabismus surgery. MATERIALS AND METHODS: A total of 96 children (1-5 years old) undergoing strabismus surgery were enrolled. Anaesthesia was induced with propofol and maintained with desflurane. After induction, fentanyl (1 microg/kg) was administered to all children. During surgery, patients were infused with 0.2 microg/(kg.h)-1 dexmedetomidine (Group FD, n=47) or normal saline (Group F, n=47). Postoperative objective pain score (OPS), Paediatric Agitation and Emergence Delirium (PAED) score, and EA score were documented every 10 minutes in the post-anaesthesia care unit. RESULTS: There were no significant differences between the two groups in demographic characteristics and haemodynamic changes. The mean values of maximum EA, maximum PAED, and maximum OPS score were significantly lower in Group FD than in Group F at 0, 10, and 20 minutes after arrival at the post-anaesthesia care unit (p<0.001). The frequency of fentanyl rescue was lower in Group FD than in Group F (p<0.001). The incidence of severe EA was significantly lower in Group FD than in Group F (12.8% vs. 74.5%, p<0.001). CONCLUSION: Intra-operative low-dose infusion of dexmedetomidine in addition to fentanyl reduces EA following desflurane anaesthesia in children undergoing strabismus surgeries.

ABSTRACT

Autosomal dominant polycystic kidney disease (ADPKD) is a systemic disorder associated with various extrarenal complications. The major cardiovascular complications of ADPKD include valvulopathies and vascular ectasia. A 64-year-old man who was diagnosed with ADPKD seven years previously was admitted to our hospital for heart failure. Pelvic computed tomography revealed multiple variable-sized cysts in both kidneys. Transthoracic echocardiography showed enlargement of the left ventricle and left atrium. Severe mitral regurgitation and moderate aortic regurgitation with annuloaortic ectasia were observed. The left main coronary artery was dilated. The patient had various cardiovascular features associated with ADPKD.

ABSTRACT

We report a case of a 41-year-old man undergoing hemodialysis who presented with a sudden fever and dyspnea. He developed a severe pericardial effusion due to methicillin-resistant Staphylococcus aureus, which was identified in both blood and pericardial fluid cultures. He was successfully treated with intravenous vancomycin for 6 weeks. Although such cases are very rare in Korea, the current case describes a primary purulent pericarditis without any other potential infectious foci.

ABSTRACT

BK virus nephropathy has emerged as an important cause of renal allograft dysfunction. Reduction in immunosuppression is the mainstay of BK virus nephropathy treatment. However, decreasing immunosuppressive medications is not sufficient for treatment of BK virus nephropathy. Therefore, there is a need for other treatment strategies such as cidofovir, leflunomide, and intravenous immunoglobulin in combination with immunosuppression reduction. Ciprofloxacin has recently been reported to have antiviral activity and decrease BK viral load in kidney transplant recipients. These findings suggest that the use of ciprofloxacin represents a valuable treatment strategy in patients with BK virus nephropathy. Here, we report on our experience with three patients who developed presumptive BK virus nephropathy after kidney transplantation, who, after 2 months of ciprofloxacin treatment, showed disappearance of BK viremia and improvement in the estimated glomerular filtration rate. Ciprofloxacin may be considered an effective treatment option for BK viremia in kidney transplant recipients.

ABSTRACT

Although the prognosis of papillary thyroid cancer (PTC) is extremely good, locoregional recurrences after initial treatment occur. Thyroglobulin (Tg) is a reliable tumor marker to detect recurrence or persistence of PTC. However, occasionally serum Tg may miss the detection of a recurrence. We report a 54-year-old female presented with hoarseness due to cervical recurrence without concomitant elevation of serum Tg and anti-Tg antibody, in contrast to extremely increased needle-washout Tg, who had undergone a total thyroidectomy and radioiodine ablation as initial therapies for PTC. Several factors causing such discrepancy between needle-washout Tg and serum Tg can be suggested including site of recurrence, volume of tumor, interference by some kind of plasma antibodies other than anti-Tg antibody, and any conformational defect of Tg protein. Among them, the most convincing explanation is that any conformational defect of Tg may lead to impaired secretion of Tg to blood. We suggest that more studies are needed to find the cause for potential mechanisms involved in PTC recurrences without increased serum Tg.
