Objective: To determine whether the administration of tamsulosin, as adjunctive medical therapy, increases the efficacy of one session of extracorporeal shock wave lithotripsy (ESWL) to treat renal stones. Material & Method: A prospective randomized placebo controlled study enrolled 21 patients. They underwent a single ESWL session to treat solitary radiopaque renal stones 4 to 20 mm in diameter. After ESWL, the study group (11) received 0,4 mg tamsulosin daily and the control group (10) received placebo until stone clearance or a maximum period of 8 weeks. The primary endpoint was stone-free rate and parameters were stone size and clearance time. Results: The overall stone-free rate was better in the study group than in the control group (90,9% vs. 60,0%). The clearance time after 2, 4, 6 and 8 weeks was greater in the study group than in the control group (36,4%; 63,6%; 72,7% and 90,9% vs 30,0%; 50,0%; and 60,0% respectively) but statistically insignificant. Conclusion: Clinically, the results of our study have demonstrated that tamsulosin therapy, as an adjunctive medical therapy after ESWL, is more effective than lithotripsy alone for the treatment of patients with renal stones. Keywords: ESWL, tamsulosin, medical expulsive therapy, renal stones.

The first-line management of renal stones between 20—30 mm remains controversial. The Extracorporeal Shock Wave Lithotripsy (ESWL) stone-free rates for such patient groups vary widely. The purpose of this study was to define factors that have a significant impact on the stone-free rate after ESWL in such controversial groups. Between January 1990 and January 2004, 594 patients with renal stones 20—30 mm in length underwent ESWL monotherapy. Stone surface area was measured for all stones. The results of treatment were evaluated after 3 months of follow-up. The stone-free rate was correlated with stone and patient characteristics using the Chi-square test; factors found to be significant were further analyzed using multivariate analysis.Repeat ESWL was needed in 56.9% of cases. Post-ESWL complications occurred in 5% of cases and post-ESWL secondary procedures were required in 5.9%. At 3-month follow-up, the overall stone-free rate was 77.2%. Using the Chi-square test, stone surface area, location, number, radiological renal picture, and congenital renal anomalies had a significant impact on the stone-free rate. Multivariate analysis excluded radiological renal picture from the logistic regression model while other factors maintained their statistically significant effect on success rate, indicating that they were independent predictors. A regression analysis model was designed to estimate the probability of stone-free status after ESWL. The sensitivity of the model was 97.4%, the specificity 90%, and the overall accuracy 95.6%.Stone surface area, location, number, and congenital renal anomalies are prognostic predictors determining stone clearance after ESWL of renal calculi of 20—30 mm. High probability of stone clearance is obtained with single stone ≤400 mm2 located in renal pelvis with no congenital anomalies. Our regression model can predict the probability of the success of ESWL in such controversial groups and can define patients who would need other treatment modality.

Objectives: To compare the stone free rate and treatment success rate between a diuretic group of patients undergoing extracorporeal shock wave lithotripsy (ESWL) and a control placebo group (normal saline solution). Materials and Methods: One hundred and ninety-four patients with solitary renal calculi or ureteric calculi size of 5 mm or over were prospectively randomized into 2 groups. Ninety-seven patients in the first group (diuretic group) underwent ESWL after intravenous injection of furosemide 40 mg, and 97 patients in the second (control) group received normal saline solution 4 ml instead of furosemide prior to ESWL. The treatment protocol included 3,000 shockwaves per patient in each session with the energy beginning at 8 and progressing up to 15 kilovolts. A maximum of 3 ESWL sessions were permitted per patient. The primary outcome was stone free rate, and the secondary outcome was treatment success rate at 3 months after the first ESWL treatment. Results: The stone free rate was 48.5% compared to 50.5% for diuretic group and control group respectively and the treatment success rate was 81.4% compared to 64.9%. The difference in stone free rate was not statistically significantly different (p = 0.87), however the treatment success was, p = 0.01. Conclusion: A combination of diuretic therapy followed by ESWL improves the treatment success rate compared with standard ESWL therapy alone.

Objectives: This study aimed to assess which of extracorporeal shock-wave lithotripsy (SWL), ureterorenoscopy (URS) or percutaneous nephrolithotomy (PCNL) offers the best stone-free rate (SFR) for 1–2 cm renal stones. Patients and methods: A total of 31 patients with renal stones between 1 and 2 cm were randomised to SWL, URS or PCNL. Repeat treatments or alternatives were performed until the patient was stone free or clinically in no further need of treatment. All patients were assessed with computed tomography scanning independently reviewed by a radiologist blinded to the treatment. Results: Overall, 10 well-matched patients were randomised to SWL, 11 to URS and 10 to PCNL. SFRs were 60% for SWL, 55% for URS and 80% for PCNL (no significant difference). The mean number of procedures required were 2.6 (range 1–7) for SWL, 2.5 (range 1–4) for URS and 1.3 (range 1–3) for PCNL ( p=0.072). There were no major complications, but 50% of SWL had minor complications compared with 9% for URS and 20% for PCNL. Conclusion: The results for SWL were disappointing for SFR, number of procedures and complications. In common with other recent studies, the SFR following URS was also poor. PCNL had the best results for SFR with the fewest procedures. We calculate that an adequately powered study will require 42 patients per arm. Level of evidence Level 2b

Abstract Objective To investigate the effects of nasal irrigation with sodium hyaluronate and surfactant solutions on mucociliary clearance time in patients with mild persistent allergic rhinitis. Methods A total of 120 patients diagnosed with mild persistent allergic rhinitis were enrolled in this prospective study. The patients were allocated randomly to the surfactant, sodium hyaluronate or isotonic saline (as a control) nasal irrigation group. The mucociliary clearance times and improvements in mucociliary clearance times were compared. Results Improvements in mean mucociliary clearance time were significantly greater in the surfactant and sodium hyaluronate groups than in the control group (p < 0.01). The mean post-treatment mucociliary clearance time of the surfactant group was significantly lower than that of the control (p < 0.001) and sodium hyaluronate groups (p = 0.03). Conclusion Surfactant and sodium hyaluronate nasal irrigation solutions may both be used as adjunctive treatments for allergic rhinitis. Surfactant nasal irrigation resulted in better mucociliary clearance times.

Background We aimed to compare the efficacy and safety of laparoscopic pyelolithotomy (LPL) versus percutaneous nephrolithotomy (PCNL) for treating renal stones larger than 2 cm. Methods We searched the PubMed, Embase, Web of Science, SinoMed, and Chinese National Knowledge Infrastructure databases for studies that compared the surgical outcomes of LPL and PCNL. We conducted a meta-analysis of the retrieved studies, expressed as weighted mean difference or risk ratios with 95% confidence intervals. Results We included 25 studies (1831 patients). LPL was associated with a significantly higher stone-free rate, lower rates of blood loss, complementary treatment, blood transfusion, and complications, and less reduction in hemoglobin level compared with PCNL. LPL and PCNL were similar in terms of duration of hospital stay, conversion rate, changes in glomerular filtration rate and creatinine level, and mean time of postoperative analgesia. However, LPL was associated with a longer operation time than PCNL. Conclusion LPL appears to be more effective and safer than PCNL in patients with large renal stones, by increasing the stone-free rate and reducing blood loss, complementary treatment, blood transfusion, and complications compared with PCNL. LPL may thus be a useful modality for treating patients with large renal stones.

This study was undertaken to investigate the effects of acupuncture in low back and pelvic pain during pregnancy under real life conditions, as compared with patients undergoing conventional treatment alone. A total of 61 conventionally treated pregnant women were allocated randomly into two groups to be treated or not by acupuncture. Twenty-seven patients formed the study group and 34 the control group. They reported the severity of pain using a Numerical Rating Scale from 0 to 10, and their capacity to perform general activities, to work, and to walk. We also assessed the use of analgesic drugs. Women were followed up for eight weeks and interviewed five times, at two-week intervals. All women completed the study. In the study group the average pain during the study period showed a larger reduction (4.8 points) than the control group (−0.3 points) (P<0.0001). Average pain scores decreased by at least 50% over time in 21 (78%) patients in the acupuncture group and in five (15%) patients in the control group (P<0.0001). Maximum pain and pain at the moment of interview were also less in the acupuncture group compared with the control group. The capacity to perform general activities, to work and to walk was improved significantly more in the study group than in the control group (P<0.05). The use of paracetamol was lower in the acupuncture group (P<0.01). These results indicate that acupuncture seems to alleviate low back and pelvic pain during pregnancy, as well as to increase the capacity for some physical activities and to diminish the need for drugs, which is a great advantage during this period.

Objective: To evaluate in an in vivo rabbit model, the effect of topical timolol maleate therapy on the central corneal thickness response to acute intraocular pressure increases. Method: In this prospective and interventional controlled study, the central corneal thickness and intraocular pressure were measured in vivo in 12 rabbit eyes treated with topical timolol maleate for 1 month and in 12 controls at baseline, and after the intraocular pressure (measured by direct cannulation of the anterior chamber) was increased to 15 and 30 mmHg using a forced saline infusion into the anterior chamber. Results: There were no significant differences in the basal central corneal thickness values (control group, 373.2±12.9 µm; study group, 377.5±19.2 µm, p=0.5) or the central corneal thickness values when the intraocular pressure was increased to 15 mmHg (control group, 335.2±14.3 µm; study group, 330.0±32.1 µm, p=0.6) and to 30 mmHg (study group, 318.8±25.3 µm; control group, 329.8±21.0 µm, p=0.3). Conclusion: Rabbit corneas treated with topical timolol maleate for 1 month did not show a strain response to acute intraocular pressure increases that differed from control eyes. This is in contrast to a previous finding in which rabbit eyes treated with prostaglandin analogues had a greater decrease in central corneal thickness in response to a sudden intraocular pressure increase compared with untreated corneas.

Abstract Background Challenges of diagnosing and treating sepsis only seem more difficult as incidence increases, patients become older and sicker, and pathogenic organisms evolve. New understanding of inflammatory mediators and pathways, immunity, and genetic variability in this disease state suggests that the current definitions of SIRS, sepsis, severe sepsis, and septic shock are oversimplified. Objective The aim of our study is to evaluate the level of RDW, CRP and clinical scores "SOFA and APACHI" as markers in patients with sepsis and their levels on the outcome and resolution of sepsis in ICU. Methodology We conducted a prospective observational controlled study on 90 adult persons of both sex, 45 of them are adult patients and served as the study group (Group I), and the other 45 are healthy adult volunteers and served as the control group (Group II). The study group represented patients admitted to the ICU of Intensive Care Unit at Damanhour Medical National Institute who fulfilled the diagnostic criteria for sepsis, severe sepsis and septic shock on arrival to ICU according to the SCCM/ ESICM/ ACCP/ ATS/SIS International Sepsis Definitions Conference. Results. In the present study we found that CRP measured on admission was not a predictor of mortality, while that measured at day 5 and day 10 predicted mortality, where there was no statistically significant difference in CRP levels between survivors and non-survivors at the day of admission while there were statistically significant differences between survivors and non survivors according to CRP levels at day 5 (p = 0.001*) and at day 10 (p = 0.001*). It was found also that there were statistically significant differences between survivors and non-survivors according to RDW at day 1(p = 0.011*) and at day 5(p = 0.009*), at day 10 was found there was no statistically significant difference between survivors and non-survivors (p = 0.338). Conclusion RDW is a new promising cheap and readily available biomarker that can be able to diagnose patients with sepsis with accuracy comparable to CRP. Also, RDW at admission is able to predict mortality.
