CONTEXT: Thermodilution, which is considered to be a standard technique for measuring the cardiac output in critically ill patients, is not free from relevant risks. There is a need to find alternative, noninvasive, automatic, simple and accurate methods for monitoring cardiac output at the bedside. OBJECTIVE: To compare cardiac output measurements by thermodilution and partial carbon dioxide rebreathing in patients with acute lung injury at two levels of severity (lung injury score, LIS: below 2.5, group A; and above 2.5, group B). TYPE OF STUDY: Comparative, prospective and controlled study. SETTING: Intensive Care Units of two university hospitals. METHODS: Cardiac output was measured by thermodilution and partial carbon dioxide rebreathing. Twenty patients with acute lung failure (PaO2/FiO2 < 300) who were under mechanical ventilation and from whom 294 measurements were taken: 164 measurements in group A (n = 11) and 130 in group B (n = 9), ranging from 14 to 15 determinations per patient. RESULTS: There was a poor positive correlation between the methods studied for the patients from groups A (r = 0.52, p < 0.001) and B (r = 0.47, p < 0.001). The application of the Bland-Altman test made it possible to expose the lack of agreement between the methods (group A: -0.9 ± 2.71 l/min; 95% CI = -1.14 to -0.48; and group B: -1.75 ± 2.05 l/min; 95% CI = -2.11 to -1.4). The comparison of the results (Student t and Mann-Whitney tests) within each group and between the groups showed significant difference (p = 0.000, p < 0.05). DISCUSSION: Errors in estimating CaCO2 (arterial CO2 content) from ETCO2 (end-tidal CO2) and situations of hyperdynamic circulation associated with dead space and/or increased shunt possibly explain our results. CONCLUSION: Under the conditions of this study, the results obtained allow us to conclude that, in patients with acute lung injury, the cardiac output determined by partial rebreathing of CO2 differs from the measurements obtained by thermodilution. This difference becomes greater, the more critical the lung injury is.

Background: Standard four port laparoscopic cholecystectomy is the gold standard in the treatment of gall stones. Modified epigastric port laparoscopic cholecystectomy may be considered an alternative, as this procedure maintains the advantages of four ports and does not require any special set of instruments. In this study we aimed to see whether this procedure is comparable to the standard four port laparoscopic cholecystectomy based on the primary objectives of postoperative pain score, degree of ambulation, time to return to normal activities.Methods: Consecutive patients due to undergo laparoscopic cholecystectomy, meeting all the predefined criteria were recruited into the study. The group A was assigned to receive intervention in the form of modified epigastric port laparoscopic cholecystectomy. The group B was assigned to receive intervention in the form of standard four port laparoscopic cholecystectomy. Patients in group A were compared with patients in group B based on multiple pre-defined parameters.Results: Pain scores were significantly better in group A. Degree of ambulation at was significantly better in group A. In respect to the time to resumption of normal activities there was no significant difference between the two groups. When comparing the quality life at 1 month following surgery with SF-36 health survey, the patients in group A did better than patients in group B with respect to the six scales. Conclusions: Modified epigastric port laparoscopic cholecystectomy appears to be significantly better than the standard four port cholecystectomy in terms of postoperative recovery.

Phosgene exposure can cause acute lung injury (ALI), for which there is no currently available effective treatment. Mesenchymal stem cells (MSCs) which have been proven to have therapeutic potential and be helpful in the treatment of various diseases, but the mechanisms underlying the function of MSCs against phosgene-induced ALI are still poorly explored. In this study, we compared the expression profiles of mRNAs, lncRNAs, and circRNAs in the lung tissues from rats of three groups—air control (group A), phosgene-exposed (group B), and phosgene + MSCs (group C). The results showed that 389 mRNAs, 198 lncRNAs, and 56 circRNAs were differently expressed between groups A and B; 130 mRNAs, 107 lncRNAs, and 35 circRNAs between groups A and C; and 41 mRNAs, 88 lncRNAs, and 18 circRNAs between groups B and C. GO and KEGG analyses indicated that the differentially expressed RNAs were mainly involved in signal transduction, immune system processes, and cancers. In addition, we used a database to predict target microRNAs (miRNAs) interacting with circRNAs and the R network software package to construct a circRNA-targeted miRNA gene network map. Our study showed new insights into changes in the RNA expression in ALI, contributing to explore the mechanisms underlying the therapeutic potential of MSCs in phosgene-induced ALI.

Introduction: We aimed to evaluate the effect of preoperative urethral dilatation during holmium laser enucleation of the prostate (HoLEP) on the prevention of urethral stricture. Methods: A total of 72 patients without urethral stricture underwent HoLEP for benign prostatic hyperplasia (BPH). Recruited patients were randomly divided into two groups (groups A and B). Patients in group A (36 patients, experimental group) received preoperative urethral dilatation and patients in group B (36 patients, control group) did not. Each patient was evaluated at four weeks, 12 weeks, and 24 weeks after surgery. The effectiveness of preoperative urethral dilatation was evaluated based on the International Prostate Symptom Score (IPSS), peak urine flow rate (Qmax), voided volume, and post-void residual (PVR) volume. To diagnose urethral stricture, Qmax <10 mL/s, as assessed using uroflowmetry and findings of visualization through retrograde urethrography and urethroscopy, were used. Results: Among 72 initial participants, 33 patients in group A and 31 patients in group B completed the experiment. Preoperative characteristics were well-balanced between groups. At each postoperative visit, there was no significant difference in voiding symptoms between groups. Two patients (6.06%) in group A and five patients (15.15%) in group B showed a Qmax <10 mL/s on uroflowmetry (p=0.013). On urethroscopy, no patient in group A (0%) and two patients in group B (6.45%) (p=0.021) showed urethral stricture after HoLEP. Conclusions: Preoperative urethral dilatation during HoLEP decreased the incidence of urethral stricture. This procedure could be useful to reduce the risk of urethral stricture after transurethral prostate surgery. One limitation of the current study is the single-centre design. Also, we sought to determine the efficacy of preoperative urethral dilatation for the prevention of urethral stricture after transurethral prostate surgery within a short time period, which could be another limitation of the study. Despite these limitations, to the best of our knowledge, the present study is the first reported prospective, randomized trial analyzing the safety and efficacy of preoperative urethral dilatation for the prevention of urethral stricture after transurethral prostate surgery.

Abstract Background Semi-rigid uretroscopy (URS) is a common intervention approach for lower ureteric stones. Ureteral dilatation is frequently needed before URS to enable ureter accessing. Aminophylline is known by its muscle relaxant effect and has been suggested to be effective in ureteral dilation. Objectives To evaluate the effect of intravesical administration of aminophylline on ureteroscopy and to measure intraureteral pressure Methods This prospective randomized controlled study included 50 before and after aminophylline injection. patients with lower ureteral calculi. In group A, the ureter was dilated by intravesical aminophylline whereas in group B balloon dilator was used. Intraureteral pressure was measured using pressure transducer connected to invasive pressure monitor. Results No statistically significant difference was noticed between both groups in operative time, intra operative complication, need for ureteral stenting or stone free rate. However, post-operative pain and haematuria were statistically significantly higher among balloon group compared to aminophylline group. In group A, there was statistically significant decrease in intraureteral pressure after injection of aminophylline (7.80 ± 1.71) compared to before injection (12.2 ± 1.85) with p-value &lt; 0.001. Conclusion Aminophylline is effective in ureteral dilatation when intravesically injected with less frequent post-operative pain and hematuria.

Background: Surgical site infections better prevented by parenteral antibiotic in sufficient doses generally should be given before the operation which helps to achieve the therapeutic drug level both in the blood and related tissue during the operation. Ceftriaxone, when administered together as a prophylaxis can fulfil the above criteria of a good antibiotic. Thus, this study was planned to assess the efficacy of prophylactic antibiotic usage to that of regular antibiotics usage in patients undergoing elective surgeries.Methods: This randomized controlled study was conducted in a tertiary care teaching hospital during the study period of June 2017 to April 2018 with 140 cases. Group A received a single dose of Injection Ceftriaxone 1g. Group B, received Injection Ceftriaxone 1 gm and Injection Metronidazole 500 mg for five days. The data was entered in excel sheet and analyzed using SPSS (Version 16).Results: The mean age group in Group A and Group B was found to be 34.24±10.5 and 35.97±11.89, respectively. There was no statistical significance between group A and B for incidence of infection in the post-operative period and duration of hospital stay. The mean value in group A for duration of surgery was found to be 67.5±13.5 and in group B mean value was 72.1±14.9. (p value <0.05).Conclusions: This study demonstrated that administration of prophylactic antibiotic rather than conventional antibiotic at caesarean and gynecological surgeries are not associated with significant difference in post-operative morbidities.

This study aims to observe the changes and the function of p38MAPK-HSP27 signaling pathways in acute lung injury (ALI) induced by acute ischemic kidney injury in rats. Wistar rats were randomly divided into Group A (control group), Group B (acute kidney injury group), and Group C (acute kidney injury +SB203580). The concentration of protein in BALF, neutrophil counts, PI, W/D; the concentration of TNF-α, IL-6, and IL-1βin plasma and BALF; and the concentrations of MDA and NO in the lung tissue started to increase 2 h after the experiment in Group B, which showed a significant difference compared with those in Groups A and C. The expressions of p-p38MAPK and p-HSP27 in the lung tissue began to increase 2 h after the experiment in Group B, which was different from those in Groups A and C. A significant increase was observed in the F-actin expression in Group B than that in Group A. In Group B, the correlation of cytokine TNF-α, IL-6, and p-p38MAPK in BALF was positive. Acute kidney injury (AKI) induced by bilateral renal arteriovenous clamp closure could activate p38MAPK-HSP27 signaling pathways and induce lung injury, which blocks the p38MAPK-HSP27 signal pathway to reduce the risk of lung injury.

Abstract Background: This study was performed to compare the efficacy of marsupialization under nasal endoscopy versus lacrimal probing for the treatment of congenital dacryocystocele. Methods: A prospective randomized controlled study. Forty neonates (43 eyes) diagnosed with congenital dacryocystoceles were divided into Group A (nasal endoscopic marsupialization) and Group B (lacrimal probing). The patients were followed up for 1 year after surgery. The efficacy, incidence of complications, and reoperation rate were compared between the two groups. Results: The male:female ratio was 25:15 patients (27:16 eyes). In Group A, the success rate was 100%, the incidence of complications was 5%, and the reoperation rate was 0%. In Group B, the success rate was 90%, the incidence of complications was 20%, and the reoperation rate was 30%. There was no significant difference in the success rate between the two groups, but the incidence of complications and the reoperation rate in the lacrimal probing group(Group B) were significantly higher than those in the nasal endoscopic marsupialization group(Group A). Conclusion: In the treatment of congenital dacryocystoceles, nasal endoscope marsupialization has the same success rate as lacrimal duct probing, but the former is more effective and safer in clinical practice.

Objective: To determine the effect of topical gentamycin application at the urethral stent to the stent’s colony-forming-unit (CFU) in hypospadias patients. Material & methods: This study is a double blind prospective randomized controlled study, conducted from November 2016 - August 2017 in Urology Department Hasan Sadikin Hospital Bandung. We include patients with distal until penoscrotal hypospadias who underwent urethroplasty for the first time. The subjects were divided into 2 groups: Group A were patients performed urethroplasty with nasogastric tube (NGT) urethral stents only. Group B were patients performed urethroplasty with NGT urethral stents that were coated with topical gentamycin. Both group were operated by a single surgeon using either Tubularized Incised Plate (TIP) or Onlay Preputial Flap technique. Both group used supra pubic urinary diversion. Both group were given the same preoperative and postoperative intravenous antibiotics and given same dressing. At post operative day 7, the stents were removed and swabbed for bacterial culture and resistance test and colony-forming-unit (CFU) counts. Demographic data is described and, among others were analyzed statistically. Other adverse events and complications were also documented. Results: There were 25 hypospadias patients who were performed urethroplasty (12 patients in Group A and 13 patients in Group B). The median age in group A was 7 ± 2.995 (years old) and the mean age in group B was 6 ± 3.178  (years old). In group A, 1 patient (8.3%) were distal shaft type, 1 patient (8.3%) were middle shaft type, 8 patients (66.7%) were penoscrotal type, 1 patient (8.3%) were proximal shaft type, and 1 patient (8.3%) were subcoronal type. In group B, 3 patients (23.1.%) were distal shaft type, 3 patients (23.1%) were middle shaft type, 5 patients (38.5%) were penoscrotal type, and 2 patients (15.7%) were proximal shaft type. In group A, 6 patients (50%) using TIP, 6 patients (50%) using onlay preputial flap. In group B, 5 patients (38.5%) using TIP, 8 patients (61.5%) using onlay preputial flap. In Group A, Staphylococus haemoliticus was the most common bacterial found in urethral stent swabbed culture (50%), followed by Pseudomonas aeroginosa (16.7%), Acinetobacter baumannii (8.3%), Enterococcus faecalis (8.3%), Morganella morgagnii (8.3%) and sterile cultures (8.3%). In Group B, 38.5% were sterile urethral stents culture, followed by Staphylococus haemoliticus (30.8%), Enterobacter cloacae (7.7%), Staphylococus warneri (7.7%), Staphylococus epidermidis (7.7%), and Moraxella catarrhalis (7.7%). The most sensitive antibiotics in both group were Amikacin, Gentamycin, Meropenem, Cotrimoxazole, and Cefepime. In group A, 11 patients (91.7%) had >100.000 CFU counts, and 1 patient (8.3%) with no colony found.  In Group B, 2 patients (15.4 %) had >100.000 CFU counts, 6 patients (46.2%) had <100.000 CFU counts, and 5 patient (38.5%) with no colony found. In group A, there were 3 patients (25%) with urethra-cutaneous fistula, 4 patients (33.3%) with hematoma, and 5 patients (38.5%) without any complications. In group B, there were 2 patients (15.4%) with urethra-cutaneous fistula, 3 patients (23.1%) with hematoma and 8 patients (61.5%) without any complication. Using Mann-Whitney U-test, we found a significant difference of CFU counts formation between the two groups (p=0.001). Statistically, the lesser CFU counts found, the lesser complication were developed (p=0.001). Conclusion: Topical gentamycin application at the urethral stents in hypospadias patients performed urethroplasty significantly reduced CFU counts found at the urethral stents and thus reduced the urethra-cutaneous fistula and hematoma formation.

Postoperative acute lung injury (ALI) compromises oxygen transfer across alveolar-capillary membrane with consecutive hypoxia, one of its indicators being reduction of oxygenation index PaO2/FiO2 below 40 kPa (300 mm Hg). Management of ALI includes different procedures like mechanical lung ventilation (MLV), drugs and others. One of the new possibilities for treatment of ALI is nitric oxide (NO) inhalation. The aim of this prospective study was to examine the role of NO inhalation in treatment of ALI. 14 patients with ALI developed immediately after operation with extracorporeal circulation (ECC) were included in the study. Group A (n = 8) inhaled NO and group B (n = 6) did not inhale NO during treatment of ALI. All other therapeutic measures were the same in both groups. The groups were similar in relation to demographic data, type of surgery and duration of ECC. PaO2/FiO2 was calculated before operation (T1), immediately after surgery (T2) and after lung recovery, when the need for MLV stopped (T3). The duration of MLV was also registered. PaO2/FiO2 (kPa) in referent times was in group A 54,9 ? 1,6, 33,8 ? 1,2 and 46,2 ? 0,8 and in group B 52,2 ? 1,1, 33,5 ? 1,5 and 47,3 ? 0,9, respectively. There was a statistically significant decrease of PaO2/FiO2 in T2 and T3 vs T1 in both groups (p < 0,05), while the difference between the groups was not statistically significant. The duration of MLV (h) in group B (28,5 ? 1,6) was statistically significantly shorter than in group A (63,1 ? 8,7) (p < 0,01). According to the results of this study we conclude that NO inhalation during ALI after surgery with ECC significantly reduces the duration of MVL and improves pulmonary recovery .
