Ultrasound-guided trans-incisional quadratus lumborum block versus ultrasound-guided caudal analgesia in pediatric open renal surgery: a randomized trial. Korean J Anesthesiol 2023; 76:471-480. [PMID: 36704815 PMCID: PMC10562062 DOI: 10.4097/kja.22774] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2022] [Revised: 01/22/2023] [Accepted: 01/24/2023] [Indexed: 01/28/2023] Open
Abstract
BACKGROUND The caudal route is a common approach for postoperative analgesia; however, it is associated with limited duration of action. The quadratus lumborum block (QLB) may produce prolonged postoperative analgesia. Therefore, this study aimed to compare the postoperative analgesic efficacy of the ultrasound-guided caudal block with that of the ultrasound-guided transincisional QLB (TiQLB) in pediatric patients undergoing open renal surgery. METHODS Forty patients of both sexes, aged 2-11 years, were randomly assigned to receive either caudal analgesia with 1.25 ml/kg of bupivacaine 0.2% (Caudal group; n = 20) or a QLB with 0.5 ml/kg of bupivacaine 0.2% (TiQLB group; n = 20) in addition to standard general anesthesia. Time to first analgesia was the primary outcome. Total analgesic consumption in the first 24 h postoperatively, pain scores, and the incidence of side effects were the secondary outcomes. RESULTS The mean time to first analgesic requirement was significantly longer in the TiQLB group than in the Caudal group (18.8 ± 5.1 vs. 6.7 ± 0.7 h, P < 0.001). Total ketorolac consumption and pain scores were significantly lower in the TiQLB group (P < 0.001). A few cases of mild postoperative nausea and vomiting were noted among patients in both groups; however, the difference was not statistically significant. No incidence of pruritus, shivering, or respiratory depression was noted. CONCLUSIONS Analgesia after the ultrasound-guided TiQLB with bupivacaine was superior to that after the ultrasound-guided caudal block, with similar side effects.

Thulium laser en bloc resection versus conventional transurethral resection of urinary bladder tumor: A comparative prospective study. Urol Ann 2023; 15:88-94. [PMID: 37006212 PMCID: PMC10062500 DOI: 10.4103/ua.ua_59_22] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2022] [Accepted: 10/11/2022] [Indexed: 04/04/2023] Open
Abstract
Background Transurethral resection of bladder tumors (TURBT) is the standard management for urinary bladder tumors; however, new techniques as Thulium laser en bloc resection of bladder tumors (TmLRBT) have been introduced as a substitute to TURBT. Objectives In this study safety, efficacy, and tumor recurrence after TmLRBT and TURBT were prospectively compared in patients with primary (<4 cm) bladder tumors. Patients and Methods Between August 2019 and May 2021, patients with primary (<4 cm) bladder tumors were enrolled. Patients were randomized between the two procedures. All perioperative data were collected prospectively. Pathological specimen findings and recurrence rates were reported during follow-up visits. Results Sixty patients underwent TURBT, and another 60 had TmLRBT. No significant differences were detected in patient demographics or preoperative tumor characteristics between the two groups. Operation time was less (28.2 vs. 38.9 min, P < 0.001), and rate of bladder perforation was lower with TmLRBT compared to TURBT (3.3% vs. 15.0%, P = 0.027). In the TmLRBT group, higher rate of muscle detection (95.0% vs. 78.3%, P < 0.001) in the pathological specimen, and lower rate of tissue destruction (0.0% vs. 21.6%, P < 0.001) were obtained compared to TURBT. Recurrence rate in cases of nonmuscle invasive bladder cancer was lower with TmLRBT (6.7% vs. 33.0%, P < 0.001). Conclusion In this study, TmLRBT showed reduced operative time with lower perforation rates. Higher detection of detrusor muscle and less tissue destruction in the pathological specimen were obtained with TmLRBT, as well as lower rates of tumor recurrence. These findings suggest that TmLRBT is a safe and efficacious substitute to TURBT in tumors <4 cm.

Early versus delayed penile prosthesis insertion for refractory ischemic priapism. Arab J Urol 2022; 21:76-81. [PMID: 37234682 PMCID: PMC10208160 DOI: 10.1080/2090598x.2022.2135290] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2022] [Revised: 09/21/2022] [Accepted: 10/09/2022] [Indexed: 11/02/2022] Open
Abstract
Objectives Penile prosthesis insertion is a well-established therapeutic option in refractory ischemic priapism but there is a lack of standardization regarding the timing of surgery, the type of prosthesis (malleable or inflatable), as well as the possible complications. In this study, we retrospectively compared early versus delayed penile prosthesis insertion in patients with refractory ischemic priapism. Methods 42 male patients who presented with refractory ischemic priapism during the period between January 2019 and January 2022 were included in this study. All patients had malleable penile prosthesis insertion by four highly experienced consultants. Patients were divided into two groups based on the time of the prosthesis insertion. 23 patients had immediate insertion of the prosthesis within the first week of the onset of priapism while the remaining 19 patients had delayed prosthesis insertion three months or later after the onset of priapism. The outcome as well as the intra- and the postoperative complications were recorded. Results Postoperative complications such as prosthesis erosion and infection were higher among the early insertion group while the delayed insertion group had higher incidence of intraoperative complications such as corporal perforation and urethral injury. The insertion of the prosthesis was much more difficult among the delayed insertion group due to fibrosis which made dilatation of the corpora very difficult. The length and the width of the penile implant were significantly higher among the early insertion group as compared to the delayed insertion group. Conclusions Early penile prosthesis insertion for refractory ischemic priapism is a safe and effective treatment option as delayed prosthesis insertion is more difficult and challenging due to corporal fibrosis and is associated with higher complication.

Abstract
Abstract
Aim
Popliteal artery aneurysms (PAAs) are increasingly treated via an endovascular approach. We present mid-term outcomes of popliteal endovascular aneurysm repair (PEVAR) from a single centre.
Method
A retrospective analysis of a prospective database of consecutive patients who underwent either elective or emergency PEVAR in a single regional vascular centre from January 2010 to August 2020. The patients underwent placement of a heparin-bonded stent-graft (Viabahn Endoprosthesis, WL Gore and Associates, Flagstaff, USA) for PAA >20mm or complications: thromboembolism, rupture or popliteal vein thrombosis. Patency and stent-graft related complications were assessed.
Results
A total of 64 PAAs (mean size 36.8±13.4mm) were treated in 56 patients (mean age 75±10.7 years, 54 (96%) male). Median follow-up was 29.5 months (IQR 36.75). 30-day mortality was 0%. Technical success rate of stent-graft insertion was 100%. 1-year and 5-year primary patency was 83% and 67% respectively; primary-assisted patency at these time points was 86% and 72%, and the corresponding secondary patency was 89% and 75%. 61 out of 64 treated limbs had >1 vessel runoff. The most frequently occurring complication was stent-graft occlusion which affected 11 (17%) limbs. Stent-graft fracture occurred in 1 patient, resulting in endoleak.
Conclusions
Viabahn Endoprosthesis can be used successfully in treatment of PAA with acceptable short- and mid-term patency rates. One in five patients in this cohort required a reintervention, with most complications occurring in the first year postoperatively. Stent-graft fracture occurred only in one patient demonstrating that PEVAR is a safe option for PAA management in the intermediate term.

Abstract
BACKGROUND General anesthesia (GA) is the preferred anesthetic modality for open renal surgeries to ensure a patent airway while the patient is in the lateral decubitus position. However, these surgeries are usually accompanied by severe postoperative pain with increased requirements for multimodal pain management strategies. Regional blocks provide better postoperative pain control with less systemic opioid consumption. OBJECTIVES The aim of this study was to describe the ultrasound (US)-guided transincisional quadratus lumborum block (TiQLB) as a new approach, and to compare the addition of dexmedetomidine to bupivacaine versus bupivacaine alone for TiQLB in combination with GA regarding postoperative analgesia and adverse effects in open renal surgery. STUDY DESIGN A prospective, randomized, double-blind, controlled trial. SETTING Ain Shams University Hospitals. METHODS Eighty patients who were scheduled for an elective open renal surgery, aged 20 to 65 years, of either gender, and American Society of Anesthesiologists physical status I to II were enrolled in the study. They were randomly allocated into 2 equal groups: group dexmedetomidine-bupivacaine (DB) (n = 40) in which patients received combined GA plus TiQLB with 30 mL bupivacaine 0.25% plus 1 mu g/kg dexmedetomidine, and group bupivacaine (B) (n = 40) in which patients received combined GA plus TiQLB with 30 mL bupivacaine 0.25% only. The primary outcome was the total morphine consumption among both groups, whereas the secondary outcomes were the Visual Analog Scale (VAS) scores and the time to first analgesic requirement during the first 24 hours. Postoperative side effects, such as sedation, nausea, vomiting, shivering, pruritus, bradycardia, hypotension, and respiratory depression, were also recorded. RESULTS Patients in the DB group experienced lower total morphine consumption and lower VAS scores when compared with patients in the B group (P < 0.001). Time to first analgesic requirement was prolonged in patients in the DB group (18.6 ± 2.4 hours) in comparison to patients in the B group (7.3 ± 1.1 hours). Ten minutes after the block there was a significant reduction in mean blood pressure and heart rate in the DB group than in the B group. Regarding postoperative adverse effects, sedation scores were higher in the DB group than in the B group, postoperative nausea, vomiting, and shivering were significantly higher in the B group than in the DB group. Bradycardia was significantly more frequent among the DB group. Although nonsignificant, pruritus was more frequent in the B group than in the DB group. No cases of respiratory depression were reported in both groups. LIMITATIONS The used technique US-guided TiQLB could be performed in open renal surgeries only. CONCLUSIONS The new approach US-guided TiQLB was effective and easy to be performed. Adding dexmedetomidine to bupivacaine in TiQLB was associated with potent and prolonged postoperative analgesia with fewer postoperative adverse effects. KEY WORDS Quadratus lumborum block, dexmedetomidine, open renal surgery, postoperative pain, bupivacaine.

Abstract
Objectives: The objective is to evaluate the relative risks of ureteric stents application while managing uric acid stones with potassium citrate in terms of stone encrustations and urinary tract infection (UTI). Patients and Methods: We prospectively enrolled patients with renal uric acid stones who received K citrate from 2013 to 2018. Patient's demographics were collected. All patients were evaluated using noncontrast computed tomography (CT) scan to measure the stone size and density. JJ ureteric stent was inserted prior to the initiation of treatment. At follow-up, all patients underwent urine analysis for pH and to detect UTI. CT was repeated at 1 month and those patients who showed incomplete stone resolution underwent another course of treatment for another month. CT was repeated prior to stent removal. The presence of encrustations was inspected and collected. Results: We collected 59 patients with a median age of 36 years (18–73) and median stone burden of 26 mm3 (15–50). The median stone density was 310 HU (175–498). Twenty-one patients (35.6%) received K citrate treatment for 1-month, while the remaining patients had 2 months treatment. Sixteen patients (27.1%) had a complete stone dissolution, 41 patients (69.5%) had more than 50% decrease of stone burden while only 2 patients (3.4%) had stones with poor dissolution. Four patients (6.8%) experienced UTI while 2 patients (3.4%) had visible JJ encrustations. Most of these complications occurred when the treatment was offered for the 2nd month. Conclusion: Short-term use of ureteral stents is safe during the management of uric acid stones with K citrate.

Abstract
Background Long anterior urethral stricture due to variable etiological factors constitutes a challenge for reconstruction. We evaluated our centers experience with cases of long anterior urethral stricture due to different etiologies that were managed by 2-stage substitution urethroplasty using buccal mucosal graft procedure. Methods During the period between November 2009 and November 2016. All cases with long anterior urethral stricture that were planned for substitution urethroplasty in our department were enrolled in this study. The first stage was excision of most fibrotic areas of the urethral plate, the remaining of the urethra is laid open and augmented with buccal mucosal graft for second stage closure after 6–9 months. Results The study included 123 patients who underwent first stage, 105 patients of them underwent second stage urethroplasty. Eighteen cases were missed after first stage. The mean (range) age was 38.4 (17–60 years). The mean (range) stricture length was 8.3 (4–13 cm). The cause of stricture was idiopathic in 47, inflammatory in 15, lichen sclerosus in 26 and post failed hypospadias repair in 35 patients. First stage was complicated by graft contracture in 11 (8.9%) patients that needed re-grafting, 5(4.1%) patient had bleeding from the buccal mucosa site that needed haemostatic sutures, oral numbness was reported in 7 (5.7%) patients. Second stage was complicated by wound dehiscence in 2(1.9%) patients, restricture in 11 (10.5%), fistula in 6 (5.7%) patients, meatal stenosis in 3 (2.9%). The overall success rate was 79.1% (83 cases out of 105) with a mean (range) follow-up of 34.7 (10–58 months). Conclusions Staged urethroplasty using buccal mucosal graft procedure is an effective surgical option for patients with long anterior urethral strictures especially for patients with lichen sclerosus and those with failed previous surgical repair.

Abstract
Background: Urolithiasis is a widespread problem, that affects up to 10% of population. Uric acid stones come second to calcium stones in prevalence (around 10% of urolithiasis). Potassium citrate is currently the treatment of choice for urine alkalization with minimal side effects and high tolerability. Aims and Objectives: This study is trying to present the outcome of oral dissolution therapy (ODT) for treating radiolucent renal stones and evaluating factors affecting its success in a prospective manner. Materials and Methods: Between 2015 and 2018, 147 patients with solitary radiolucent renal stones were offered ODT using potassium sodium hydrogen citrate (K citrate). The study included patients diagnosed by noncontrast computed tomography (NCCT) with stone size of 5–30 mm in the longest dimension and attenuation less than 600 Hounsfield units (HU). Patient compliance, blood pressure, creatinine level, K level, and tolerance to side effects were followed up at days 3, 7, and 15 and then monthly for 3 months. Follow-up renal ultrasound at 6-week intervals and a final NCCT at the end of treatment. Successful dissolution was defined as complete stone dissolution or residual that measures up to 2 mm in maximum length. Data were collected, tabulated, and analyzed using Stata 12.0 software (Stata Corporation, College Station, TX, USA). Results: One hundred and thirty-nine patients were included in the analyses. The age was 45.1 ± 10.5 years. DJ stent was used in 47 (33.8%) patients. Overall response rate was 64.8%. The stone location within the kidney (pelvic or calyceal) showed no difference between responders and non-responders. Stone longest diameter was smaller in responders (17 ± 5.7 mm) versus 19.2 ± 6.1 mm in nonresponders (P value = 0.039). The mean stone attenuation value (HU) was also lower in responders (347.4 ± 68.5 HU) versus (428.9 ± 84.0 HU) in nonresponders with P < 0.001. DJ insertions seemed to have marginal effect on stone dissolution on univariate analysis but found insignificant in multivariate analysis. Conclusion: ODT is safe and effective in the treatment of radiolucent renal stones. The efficacy was affected by stone density and stone size with more tendencies to failure with bigger stones and denser stones. Double J stent insertion may facilitate dissolution rate. There was no effect of the baseline urinarypH, hyperuricemia, or stone location on the dissolution rate of the stones.

Abstract
Henoch-Schönlein purpura (HSP) is a systemic vasculitis affecting the small vessels that mainly presents in children and young adults. It is characterized by tissue deposition of immunoglobulin A (IgA) immune complexes with the classic manifestations of purpura, arthritis, arthralgia, and gastrointestinal and renal involvements. We report a case of HSP nephritis that occurred 2 years after living-donor liver transplantation (LDLT). After pulse steroid administration, the patient's symptoms disappeared and blood markers normalized. To the best of our knowledge, this is the first HSP case to be reported in a liver transplant recipient.

Abstract
BACKGROUND Colon cancer accompanying decompensated liver cirrhosis is a rare clinical condition. Usually, treatment of colon cancer is prioritized, with cirrhosis dealt with later. CASE REPORT We present a case of end-stage liver disease due to nonalcoholic steatohepatitis evaluated for living donor liver transplant. During the pretransplant examination, an ascending colon cancer was detected. Liver function was too poor to perform colon resection first. Simultaneous living donor liver transplant and colonic resection were carried out. The patient developed left lung metastasis at 2 different times during the first postoperative year, and both of them were resected. The patient received the standard chemoradiotherapy. Now, the patient is alive at 42 months postprocedure and recurrence-free at 31 months postoperatively. CONCLUSION Simultaneous liver transplantation and colon resection are possible with acceptable long-term outcomes. Immunosuppressive therapy after transplantation increases the risk for cancer recurrence. So the patient should undergo close surveillance.

Abstract
BACKGROUND To evaluate the expression of beta-catenin (β-catenin) and SKP2 proteins in superficial bladder cancer cases and their correlation with tumor grade and stage. METHODS After institutional review board approval, we retrospectively evaluated the expression of β-catenin and SKP2 proteins in tissue specimens from patients with non-muscle invasive bladder cancer (NMIBC) and compared their results with a cohort of chronic nonspecific cystitis's. Then we and explored these markers association with tumor grade and stage. RESULTS A total of 40 patients were retrospectively identified, 50% was NMIBC and the rest were chronic nonspecific cystitis. β-catenin was expressed in 18 (90%) patients of the NMIBC group in comparison to 14 (70%) of the control group with (P=0.1), while SKP2 protein was only expressed in NMIBC groups (P=0.03). A statistically significant correlation was identified between nucleocytoplasmic localization of β-catenin and SKP2 with tumor grade, stage. CONCLUSIONS β-catenin and SKP2 expression are providing promising results for differentiating higher grade and stage non muscle invasive bladder cancers.

Abstract
The aim of this study was to explore the risk factors for and how to avoid re-laparotomy after caesarean delivery and to present the experience of a university tertiary care referral hospital. The study comprised of 2,000 caesarean deliveries, among which re-laparotomy was needed in 18 patients (0.9). The study found that 16 of the 18 cases that needed re-laparotomy had previous caesarean sections (CS) and 9/18 had placenta praevia. The main indication for the procedure was internal haemorrhage (haemoperitoneum) (12/18, 66.6%). Significant haemoperitoneum of > 2 litres was reported in six cases (33.3%). Maternal mortality occurred in 3/18 (16.6%) patients. The uterus was preserved in most patients (15 patients, 83.3%). A total of 12 patients needed re-suturing of the uterine incision; 10 patients had bilateral uterine artery ligation; and four patients had bilateral internal iliac artery ligation. Uterine compression B-Lynch suturing was needed in five patients with uterine atony. Six patients (33.3%) were admitted to the intensive care unit (ICU) and were discharged well. Re-laparotomy after caesarean delivery has many risk factors leading to postoperative haemorrhage. Early signs, such as tachycardia and hypotension must be closely monitored to allow early intervention and to avoid morbidity and mortality related to late re-laparotomy.

Abstract
Hepatocellular carcinoma (HCC) is the fifth most common malignancy worldwide. In Egypt, the incidence of HCC has doubled over the last decade. Matrix metalloproteinase-9 (MMP-9) plays a key role in cancer invasion and metastasis by degrading the extracellular matrix and basement membrane barriers. A cytosine (C)/thymidine (T) single nucleotide polymorphism at position -1562 in the MMP-9 promoter is reported to influence the expression of the MMP-9 gene. The association between MMP-9 gene polymorphisms and HCC patients with hepatitis C and B viruses (HCV and HBV) was examined in 91 patients with HCC and viral hepatitis (55 HCV and 36 HBV). The results were compared with those of 42 HCC patients without viral hepatitis and 60 healthy individuals with no liver infection. Polymorphisms of the MMP-9 gene were investigated by polymerase chain reaction amplification followed by restriction fragment length polymorphism analysis. The serum MMP-9 level was quantitatively determined using a human MMP-9 enzyme-linked immunosorbent assay, which showed that homozygosity of the MMP-9 promoter (TT) was more frequent in patients with HCC and chronic HCV or HBV infection when compared with the control group (49.1, 52.8, and 35.7%, respectively). In addition, we observed significant elevation of serum MMP-9 levels in all HCC groups compared to controls. It was concluded that patients with the MMP-9 TT genotype are at risk of developing HCC and HBV or HCV. People with significantly elevated serum levels of MMP-9 are at risk of developing HCC.

Abstract
This study comprised of 65 infertile patients with systemic lupus erythematosus (SLE). The aim was to study causes and different modalities used for the management of subfertile patients with SLE. All patients were diagnosed to have SLE according to the standard criteria of diagnosis. All patients were scheduled to expectant treatment, ovulation induction and timed intercourse, intrauterine insemination (IUI), intracytoplasmic sperm injection (ICSI). Anovulation was in 20 patients (20%), due to PCOS in 10 cases and due to other causes in three patients. A total of 28 patients (43.1%) needed laparoscopy for their work-up of infertility. Male factor for infertility was present in nine couples (16.7%). Ovulation induction and timed intercourse was adopted for a maximum 6 cycles and IUI for 3 cycles. In vitro fertilisation (IVF)/ICSI was needed in five cases using standard long agonist protocol. Four cases were complicated by significant ovarian hyperstimulation syndrome after conventional ovarian stimulation and cycles were cancelled. Pregnancy occurred in 20 women. Ovarian stimulation for ovulation induction and IVF seems to be safe and successful in well selected women with non-complicated SLE.

Abstract
The objective of this study was to test the use of letrozole in combination with follicle-stimulating hormone (FSH) vs clomiphene citrate (CC) with FSH for ovarian hyperstimulation prior to intrauterine insemination (IUI). A prospective randomised trial in which 280 women with unexplained infertility were randomised to 100 mg of CC (141 patients, 219 cycles) or 5 mg of letrozole daily (139 patients, 215 cycles) for 5 days starting on day 3 of menses both combined with gonadotropins for ovarian stimulation prior to IUI. The primary outcome measures were the number of growing and mature follicles, the concentrations of serum E2 (pg/ml) and progesterone (ng/ml), and the endometrial thickness (mm). The secondary outcome measure was the occurrence of pregnancy and miscarriage. The total number of follicles was significantly greater in the CC group (4.1 +/- 0.46 vs 2.6 +/- 0.43). There was no significant difference in endometrial thickness between the two groups. Pregnancy occurred in 33 out of 139 patients (215 cycles) in the letrozole group (23.7% and 15.3%, respectively) and 37 out of 141 patients (219 cycles) (26.2% and 16.8%, respectively) in the CC group; the differences were not statistically significant. The allied use of either CC or letrozole, during ovarian stimulation to reduce the dose of gonadotropins prior to IUI is justified. This approach will reduce the cost of stimulation protocols without effect on the treatment outcome and letrozole has no advantage over CC in this respect.

Abstract
Many of the menopausal manifestations look like those accredited to thyroid hyperfunction or hypofunction. Can thyroid dysfunction explicate severe menopausal symptoms? The study comprised 350 women with different menopausal symptoms. All women had serum TSH, T3 and free T4 estimated. Women with thyroid dysfunction were appropriately treated and other women were treated with ERT. The study showed that 21 women (6%) had hypothyroidism and 18 (5.1%) had hyperthyroidism. Marked improvement in the menopausal-like symptoms occurred after treatment of the thyroid dysfunction. Elderly women with severe or resistant menopausal symptoms can be offered TSH, T3 and T4 assays to rule out the thyroid disturbances before attempting hormone replacement therapy.

Abstract
In this prospective randomized study, women with idiopathic karyotypically normal premature ovarian failure (POF) were treated with gonadotrophin-releasing hormone (GnRH) agonist and gonadotrophins with and without the addition of corticosteroids in an attempt to restore ovarian function. The study comprised 58 women with idiopathic POF randomly allocated to either GnRH agonists (GnRHa) plus gonadotrophin therapy with the addition of corticosteroids (29 patients) or GnRHa plus gonadotrophin therapy with placebo (29 patients). Ovulation occurred in six cases (20.7%) in the dexamethasone group versus three cases (10.3%) in the placebo group. There were two singleton pregnancies in the dexamethasone group. There were no reported complications from the use of dexamethasone apart from a sense of sleepiness and fatigue. The combination of corticosteroids with pituitary suppression followed by ovarian stimulation with gonadotrophin appeared to be beneficial in restoring ovarian function in patients with idiopathic POF and normal karyotype.

Abstract
The aromatase inhibitor letrozole is a novel agent that can be used as an alternative to clomiphene citrate for ovulation induction in patients with unexplained infertility. The dose of letrozole used has varied between studies, and this study aimed to compare the three most commonly used doses: 2.5, 5 and 7.5 mg. A total of 179 patients were randomly recruited in this prospective study with 58, 61 and 60 patients in each dosage group respectively. This study reports a significantly higher (P < 0.05) number of follicles (total, > 14 mm and > or = 18 mm) on the day of administration of human chorionic gonadotrophin in the 7.5 mg group, associated with significantly fewer (P < 0.05) days of stimulation. However the pregnancy and miscarriage rates were similar in the three groups. In conclusion, it seems that the use of higher doses of letrozole offers no advantage in terms of pregnancy rates over the lower (2.5 mg) dose.

Abstract
Studying brainstem auditory evoked potentials (BAEPs) and comparing the specific waves in smokers vs nonsmokers in both positive- and negative-symptom schizophrenia may elucidate the role of smoking in information processing. BAEPs were recorded in 40 patients with schizophrenia; 20 had predominantly positive symptoms (10 smokers and 10 nonsmokers) and 20 had predominantly negative symptoms (10 smokers and 10 nonsmokers). The severity of positive and negative symptoms was assessed by scale of assessment of positive symptoms and scale of assessment of negative symptoms (SANS). The BAEP results were compared with 15 healthy control individuals matched with the patients by age, sex, and cultural background. The smokers with negative symptoms showed a significant increase in the alogia, summary, and composite scores of SANS as compared to the nonsmokers. Although, most of the BAEP abnormalities were among patients with positive symptoms. The effect of smoking on the BAEPs was only in patients with negative symptoms. We also studied the interaction between smoking factor (smokers vs nonsmokers) and group type (group with mostly positive symptoms vs group with mostly negative symptoms) on the BAEPs and found a significant difference only for the first-wave latency mainly on the right side (P=0.012). The absence of a significant effect of smoking on most of the parameters of the BAEPs on interaction with the group factor suggests that the effect of smoking on the BAEPs is more apparent when negative symptoms prevail. However, studies are warranted to substantiate this finding.

Abstract
This work studied the histopathological changes and the changes in the expression of macrophage adhesion molecule-1 (Mac-1) and macrophage inflammatory protein-1alpha (MIP-1alpha) in a murine model of soluble egg antigen (SEA) - induced granulomatous hyporesponsiveness. Histopathological results of hepatic sections in an SEA group showed early acceleration of ova destruction and markedly diminished granuloma cellularity with eosinophils and macrophages still being the predominant cells. Later, giant cells and pigmented macrophages that were scattered among granuloma cells and in intimate contact with the deposited eggs were more predominant in the SEA group than in the infected control group. Concurrently, the counts of Mac-1 positive cells were significantly increased in liver sections of the SEA group than the infected control group during the course of infection. MIP-1alpha showed early higher counts followed by lower counts in the later stages of infection on granuloma cells in the SEA group than the infected control group. During the course of infection, similar distribution of Mac-1 and MIP-1alpha was present in both groups. This study suggests that sensitization with SEA probably leads to enhancement of phagocytic activity of macrophages via increasing expression of Mac-1 and hence engulfment of ic3b coated schistosomal products such as ova. It leads to rapid destruction of ova and hence decreases the host inflammatory response to infection and amelioration of hepatic pathology which would be a promising approach in reduction of host morbidity and mortality.

Abstract
Between March 1997 and March 1998, three consecutive patients underwent laparoscopic cystogastrostomy for persistent giant retrogastric pancreatic pseudocyst complicating an attack of acute pancreatitis. The mean cyst diameter was 15 +/- 1 cm (range 14-16). The procedure was performed with four trocars. The anterior wall of the stomach was opened longitudinally. The pseudocyst was entered through the posterior wall of the stomach. A cystogastrostomy was created by suturing the margins of the communication by interrupted nonabsorbable sutures. The mean operative time was 123 +/- 15 min, and there were no postoperative complications. The mean postoperative hospital stay was 4 +/- 1 days. Computed tomography demonstrated complete resolution of the pseudocyst. Laparoscopic cystogastrostomy represents a good therapeutic option for persistent retrogastric pancreatic pseudocyst.

Abstract
The anti-miracidial potential of recombinant Schistosoma mansoni glutathione S-transferase 26 (rSmGST26) or native crude soluble egg antigens (SEA) was assessed. The associated dynamics of granuloma formation and immune responses were evaluated. Naive C57BL/6 mice were injected intravenously with multiple doses of either SEA (SEA-group) or rSmGST26 (GST-group) 7 days before cercarial infection. The immunized groups and the respective controls were sacrificed 6, 8 and 16 weeks postinfection (p.i.). Acceleration of ova destruction and reduction of granuloma diameter were greater in the GST-group than the SEA-group, mainly at 8 weeks p.i. However, the amelioration of hepatic pathology and function was more evident in the SEA-group. Concurrently, serum-specific IgG1 levels were elevated throughout the course of infection in the immunized groups compared to the infected controls. Initial rise of all splenic cytokines and serum anti-SEA IgE levels at 6 weeks p.i. was observed, followed by a dramatic drop in the levels of the proinflammatory cytokines IL-2, IFNgamma, IL-4 and TNF-alpha and IgE at 8 weeks of infection. IL-10 level was lower at 8 weeks p.i. than at 6 weeks, but was higher in immunized groups than in infected controls. Several responses may be implicated as an outcome of the present immunization protocol, such as increased levels of blocking antibody (IgG1) and IL-10 with decreased levels of proinflammatory cytokines and IgE.

Abstract
PURPOSE To determine the feasibility, operative risk and patients' benefit of laparoscopy in emergency cholecystectomy for acute calculous cholecystitis. PATIENTS AND METHODS From January 1991 to December 1998, 234 patients with acute calculous cholecystitis were operated on by emergency laparoscopic cholecystectomy. There were 131 women and 103 men (mean age: 57 years), (Asa 2: 48%, Asa 3: 10%). In seven patients, choledocolithiasis was detected by endoscopic ultrasonography and preoperatively treated by endoscopic sphincterotomy. The mean delay between in-hospital admission and cholecystectomy was 20 hours (2-160). Cholecystectomy was performed with primary approach of Calot's triangle. Intraoperative cholangiography, selectively performed (n = 70), detected choledocolithiasis in three patients. RESULTS The mean duration of surgery was 149 minutes (62-313). The conversion rate was 13% and decreased through the years. The postoperative complication rate was 18%. Eight patients (3.4%) had an abdominal complication. One patient (0.4%) died of bile peritonitis after intraoperative undetected main bile duct injury. The mean postoperative hospital stay was 6.04 days. It was 3.5 days only, very old patients and those with severe associated disease being excluded. CONCLUSION Laparoscopy appears to be a good approach for emergency cholecystectomy in patients with acute calculous cholecystitis.

Abstract
BACKGROUND Although several recent reports described the different methods utilized for laparoscopic colon resection, only a few of them questioned whether the procedure is appropriate for the surgical treatment of diverticular disease. To assess this question, we performed a retrospective study of 50 consecutive patients operated using laparoscopic assistance to remove the sigmoid colon for diverticular disease. METHOD The surgical technique was a laparoscopically assisted procedure that included mobilization of the left colon and vascular ligation laparoscopically and then, via a small abdominal incision, division of the colon, removal of the specimen, and hand-sewn anastomosis. RESULTS The surgical goal was achieved in 46 cases, with a conversion rate of 8%. The mean operative time was 195 min (range 150-280 min). There was no mortality, and the morbidity rate was 14%. There were no complications directly related to the laparoscopic technique. The mean return of regular bowel habits was 3.2 days, and the median postoperative stay was 10 days. CONCLUSIONS These preliminary results suggest that laparoscopic-assisted sigmoidectomy can be used safely for the surgical treatment of diverticular disease.
