RESUMO

BACKGROUND: The combined impact of complete resection (oncological goal) and no functional loss (functional goal) in glioblastoma subgroups is currently unknown. This study aimed to develop a novel onco-functional outcome (OFO) to merge these two goals into one outcome, resulting in four classes: complete without deficits (OFO1), incomplete without deficits (OFO2), complete with deficits (OFO3), or incomplete with deficits (OFO4). METHODS: Between 2010-2020, 858 patients with tumor resection for eloquent glioblastoma were included. We analyzed the impact of OFO class on postoperative surgical outcomes using Cox proportional-hazards models with hazard ratios (HR) or logistic regression with odds ratios (OR), followed by specific subgroup analyses. We developed a risk model to predict OFO class preoperatively using logistic regression. RESULTS: The OFO classification stratified the four OFO classes for overall survival (OS:19.0 versus 14.0 versus 12.0 versus 9.0 months), progression-free survival (PFS), and adjuvant therapy. OFO1 was associated with improved OS [HR= 0.67, (0.55-0.81); p < 0.001], and PFS [HR = 0.68, (0.57-0.81); p < 0.001] in the overall cohort and all clinical and molecular subgroups, except for MGMT-unmethylated tumors; and higher rate of adjuvant therapy [OR= 2.81, (1.71-4.84);p < 0.001]. In patients≥ 70 years, only OFO1 improved their survival outcomes. Safe surgery was especially important in patients with a preoperative KPS ≤ 80 to qualify for adjuvant treatment. Awake craniotomy more often led to OFO1 compared to asleep resection [OR = 1.93, (1.19-3.14); p = 0.008]. CONCLUSIONS: OFO1 was associated with improved OS, PFS, and receipt of adjuvant therapy in all glioblastoma patients with IDH-wildtype and MGMT-methylated tumors. Awake craniotomy was associated with achieving this optimal OFO status. Preventing deficits was more important than complete surgery.

RESUMO

BACKGROUND: Using the sandwich osteotomy technique in the posterior mandible is delicate. This study aimed to assess the safety and the amount of bone gain using a full digital workflow versus the conventional procedure. PATIENTS AND METHODS: This split mouth study included 10 patients with bilateral vertically deficient posterior mandible. One side received conventional sandwich interpositional bone grafting (control group), while the other side received the same protocol using two patient-specific guides. The first guide (cutting guide) was used to place the osteotomies safely and accurately according to the predetermined dimensions and locations, and the second guide was used to fix the mobilized bony segment, leaving the desired gap to be filled with a particulate xenogenic bone graft. RESULTS: Full neurosensory recovery was documented at 2 months postoperative for all patients and bilaterally. After 4 months, there was a statistically significant difference in vertical bone gain between both groups (p = 0.001), measuring an average of 3.76 ± 0.72 mm in the study group and 2.69 ± 0.37 mm in the control group. No statistically significant difference was found between the planned vertical augmentation (3.85 ± 0.58 mm) and the obtained vertical bone gain (3.76 ± 0.72 mm) in the study group (p = 0.765) proving the accuracy of the guided procedure. CONCLUSION: Computer-guided sandwich interpositional grafting is predictable regarding the execution of the osteotomies and the accuracy of fixation of the transport segment.

RESUMO

Over the past three decades, a notable rise in the occurrence of enteric protozoan pathogens, especially Giardia and Cryptosporidium spp., in drinking water sources has been observed. This rise could be attributed not only to an actual increase in water contamination but also to improvements in detection methods. These waterborne pathogens have played a pivotal role in disease outbreaks and the overall escalation of disease rates in both developed and developing nations worldwide. Consequently, the control of waterborne diseases has become a vital component of public health policies and a primary objective of drinking water treatment plants (DWTPs). Limited studies applied real-time PCR (qPCR) and/or immunofluorescence assay (IFA) for monitoring Giardia and Cryptosporidium spp., particularly in developing countries like Egypt. Water samples from two conventional drinking water treatment plants and two compact units (CUs) were analyzed using both IFA and qPCR methods to detect Giardia and Cryptosporidium. Using qPCR and IFA, the conventional DWTPs showed complete removal of Giardia and Cryptosporidium, whereas Mansheyat Alqanater and Niklah CUs achieved only partial removal. Specifically, Cryptosporidium gene copies removal rates were 33.33% and 60% for Mansheyat Alqanater and Niklah CUs, respectively. Niklah CU also removed 50% of Giardia gene copies, but no Giardia gene copies were removed by Mansheyat Alqanater CU. Using IFA, both Mansheyat Alqanater and Niklah CUs showed a similar removal rate of 50% for Giardia cysts. Additionally, Niklah CU achieved a 50% removal of Cryptosporidium oocysts, whereas Mansheyat Alqanater CU did not show any removal of Cryptosporidium oocysts. Conventional DWTPs were more effective than CUs in removing enteric protozoa. The contamination of drinking water by enteric pathogenic protozoa remains a significant issue globally, leading to increased disease rates. Infectious disease surveillance in drinking water is an important epidemiological tool to monitor the health of a population.

RESUMO

INTRODUCTION: Synthetic mid-urethral slings (MUSs) are the gold standard treatment for female stress urinary incontinence (SUI). Recently, there have been reports of serious adverse events with synthetic tapes such as urethral erosion, vaginal erosion, and mesh infection. Tension-free vaginal flap (TVF) operation has been proven to be successful as a natural alternative to synthetic slings. We propose our novel technique, the transobturator tension-free vaginal flap (TO-TVF), utilizing native vaginal tissue and being suspended via transobturator route. METHODS: This prospective study was conducted on 72 female patients with SUI, presenting at Alexandria University Hospital. Patients were randomized into 2 groups, group 1: 37 patients subjected to TO-TVF and group 2: 35 patients to conventional transobturator tape (TOT). In TO-TVF, a rectangular vaginal wall flap is created. A polypropylene monofilament mesh is sutured to each edge of the vaginal flap. This is inserted like conventional outside-in TOT. Patients were subjected to PGI and UDI-6 questionnaires and urodynamic study before and 6 months postoperatively. RESULTS: Both groups showed comparable and significant improvements in questionnaires. Mean operative time for TO-TVF and conventional TOT was 26.31 ± 5.2 min and 21.8 ± 3.1 min, respectively. Cure rate was 89% in group 1 and 91.4% in group 2, which was not statistically significant. No significant intraoperative complications were encountered. We had no cases of vaginal or urethral erosion in both groups. CONCLUSIONS: TO-TVF is a cost-effective, feasible, safe, and effective surgical alternative to synthetic MUS. Synthetic mesh tissue anchoring properties are maintained for better adjustment of tension. However, long-term follow-up on a large cohort of patients is still needed.

RESUMO

OBJECTIVE: We hypothesized that videolaryngoscope use for tracheal intubations would differ across NICUs, be associated with higher first attempt success and lower adverse events. STUDY DESIGN: Data from the National Emergency Airway Registry for Neonates (01/2015 to 12/2017) included intubation with direct laryngoscope or videolaryngoscope. Primary outcome was first attempt success. Secondary outcomes were adverse tracheal intubation associated events and severe desaturation. RESULTS: Of 2730 encounters (13 NICUs), 626 (23%) utilized a videolaryngoscope (3% to 64% per site). Videolaryngoscope use was associated with higher first attempt success (p < 0.001), lower adverse tracheal intubation associated events (p < 0.001), but no difference in severe desaturation. After adjustment, videolaryngoscope use was not associated with higher first attempt success (OR:1.18, p = 0.136), but was associated with lower tracheal intubation associated events (OR:0.45, p < 0.001). CONCLUSION: Videolaryngoscope use is variable, not independently associated with higher first attempt success but associated with fewer tracheal intubation associated events.

RESUMO

BACKGROUND: Kidney stone disease contributes to a significant proportion of routine urological practice and remains a common cause of worldwide morbidity. The main aim of this clinical-pilot study was to investigate the effect of flexible ureterorenoscopy (FURS) on pre- and peri-operative clinical information, physiological observations and outcome measures. METHODS: Included were 51 patients (31 males, 20 females), who underwent elective FURS, for the treatment of kidney stones. Pre-operative and peri-operative clinical information, and post-operative physiological observations and outcome measures were collected using a standard case report form. Pre-operative clinical information included age, gender, BMI, previous history of stone formation and hypertension. Pre-operative stone information included the size (mm), Hounsfield units (HU), laterality and intra-renal anatomical location. Peri-operative surgical details included surgical time in minutes; Laser use; Duration and energy of laser; and post-operative stenting. The physiological outcomes measured included systolic and diastolic blood pressure (mmHg), Likert pain score, temperature, heart rate (bpm) and respiration rate (bpm). Following initial descriptive analysis, a series of Pearson's correlation coefficient tests were performed to investigate the relationship between surgical factors other variable factors. RESULTS: A series of significant, positive correlations were observed between; age and surgical time (p = 0.014, r = 0.373); stone size and Hounsfield unit (p = 0.029, r = 0.406); surgical time and duration of laser (p < 0.001, r = 0.702); surgical time and BMI (p = 0.035, r = 0.322); baseline heart rate and Hounsfield unit (p = 0.026, r = - 0.414); base line heart rate and BMI (p = 0.030, r = 0.307).; heart rate at 120-min post FURS and age (p = 0.038, r = - 0.308); baseline pain score and BMI (p = 0.010, r = 0.361); baseline respiration rate and BMI (p = 0.037, r = 0.296); respiration rate at 240-min post FURS and BMI (p = 0.038, r = 0.329); respiration rate at 120 min post FURS and age (p = 0.022, r = - 0.330). Four patients developed post-operative complications (3-UTIs with urinary retention, 1-urosepsis). CONCLUSIONS: We report that following FURS there is an association between various physiological, clinical and surgical parameters. Although these correlations are weak, they warrant further investigation as these may be linked with untoward complications, such as infection that can occur following FURS. This data, however, will need to be validated and reproduced in larger multi-centre studies.

RESUMO

Loss-of-function mutations in the MEN1 tumor-suppressor gene cause the multiple endocrine neoplasia type 1 syndrome. Menin, the MEN1 gene product, is expressed in many tissues, including bone, where its function remains elusive. We conditionally inactivated menin in mesenchymal stem cells (MSCs) using paired-related homeobox 1 (Prx1)-Cre and compared resultant skeletal phenotypes of Prx1-Cre;Men1 f/f menin-knockout mice (KO) and wild-type controls using in vivo and in vitro experimental approaches and mechanics simulation. Dual-energy X-ray absorptiometry demonstrated significantly reduced bone mineral density, and 3-dimensional micro-CT imaging revealed a decrease in trabecular bone volume, altered trabecular structure, and an increase in trabecular separation in KO mice at 6 and 9 months of age. Numbers of osteoblasts were unaltered, and dynamic histomorphometry demonstrated unaltered bone formation; however, osteoclast number and activity and receptor activator of NF-κB ligand/osteoprotegerin (RANKL/OPG) mRNA profiles were increased, supporting increased osteoclastogenesis and bone resorption. In vitro, proliferative capabilities of bone marrow stem cells and differentiation of osteoblasts and mineralization were unaltered; however, osteoclast generation was increased. Gross femur geometrical alterations observed included significant reductions in length and in mid-metaphyseal cross-sectional area. Atomic force microscopy demonstrated significant decreases in elasticity of both cortical and trabecular bone at the nanoscale, whereas three-point bending tests demonstrated a 30% reduction in bone stiffness; finite element analysis showed morphological changes of the femur microgeometry and a significantly diminished femur flexural rigidity. The biomechanical results demonstrated the detrimental outcome of the accelerated osteoclastic bone resorption. Our studies have a twofold implication; first, MEN1 deletion from MSCs can negatively regulate bone mass and bone biomechanics, and second, the experimental and computational biomechanical analyses employed in the present study should be applicable for improved phenotypic characterization of murine bone. Furthermore, our findings of critical menin function in bone may underpin the more severe skeletal phenotype found in hyperparathyroidism associated with loss-of-function of the MEN1 gene. © 2022 The Authors.

RESUMO

PURPOSE: To evaluate the use of magnetic resonance imaging (MRI) in preoperative delineation and surgical planning for the management of female urethral and periurethral cystic vaginal swellings, with emphasis on postoperative surgical outcomes. MATERIALS AND METHODS: This is a retrospective analysis of females complaining of periurethral and urethral cystic swellings referred to our tertiary center, who underwent MRI for preoperative planning in the period from January 2014 till January 2021, with a total number of 57 patients. Data retrieved from the medical records included: patients' demographics, presenting symptoms and signs, preoperative radiological investigations, duration of symptoms, previous surgical intervention, detailed intraoperative data, postoperative complications, and postoperative follow-up. RESULTS: Urethral diverticulum was the commonest cystic lesion representing (64.9%) followed by Skene gland cysts in 14%, Mullerian cysts in 7%, Gartner cysts in 3.5%, and dermoid inclusion cysts in 10.5%. MRI precisely diagnosed the various pathological entities and anatomical complex lesions prior to surgery. This was confirmed after surgery and pathology analysis. All patients were followed up with a mean duration of 35 months, without any evidence of recurrence. CONCLUSION: MRI as a standalone imaging technique is mandatory for diagnosis of all urethral and periurethral cystic lesions, as it offers the most accurate diagnostic modality for delineation of these lesions and hence aids in the preoperative surgical planning, aiming to avoid recurrence and improving surgical outcomes.

RESUMO

INTRODUCTION: Proximal hypospadias (PPH) repair is a challenge. Dilemma exists whether to do it in single or staged repair. Staged repair is our adopted procedure which was recently modified by Snodgrass into staged tubularized autograft repair (STAG), in which attention was given to ventral straightening of the penis together with some other technical details. Herein, we report our experience with STAG in a cohort of primary posterior hypospadias. PATIENTS AND METHODS: In the period from 2011 to 2018 we operated 43 primary posterior hypospadias. Two principal surgeons (HB, MY) and multiple assistants operate children the same way, and data are recorded in a prospectively designed data base. In all children, inner prepuce graft was utilized, when curvature is more than 30 degrees, plate transection with or without ventral corporotomies were adopted. RESULTS: Forty-three children with PPH and ventral curvature more than 30 degrees underwent first stage with median age 12 months (6-132 IQR16). Penile curvature was corrected by plate transection in 27 children (62.8%), ventral corporotomies in 16 children (37.2%). Graft take was successful in 90.7%, 4 children needed revision of fibrotic graft. Second stage was completed in 37 children, success was 56.8%, 21.6% fistula, 24.3% glanular dehiscence. Overall success after third surgery to correct complications was 78.4%. In a mean follow up of 3.2 years, we had recurrence of curvature in 2 children taking success rate to 72.9%. No meatal stenosis, no diverticulum, no stricture, no urethral dehiscence was encountered. Cosmetic appearance was excellent in follow up. CONCLUSION: STAG achieves proper straightening of the penis and allows for reconstruction of a good urethra, yet urethrocutaneous fistula and glanular dehiscence remain the main complications. Follow up is important to address results of ventral corporotomies. TYPE OF STUDY: Therapeutic. LEVEL OF EVIDENCE: Level IV case series with no comparison group.

RESUMO

BACKGROUND: The number of patients diagnosed and subsequently treated for kidney stones is increasing, and as such the number of post-operative complications is likely to increase. At present, little is known about the role of specific biomarkers, following flexible ureterorenoscopy (FURS) for the surgical treatment of kidney stones. The main aim of the study was to evaluate the role of kidney and infection biomarkers, in patients undergoing FURS. METHODS: Included were 37 patients (24 males, 13 females), who underwent elective FURS, for the treatment of kidney stones. Venous blood samples were collected from each patient: pre-operatively, and at 30 min, 2 and 4 h post-operatively. Changes to kidney (NGAL, Cystatin-C) and infection (MPO, PCT) biomarkers was quantified by means of ELISA, Biomerieux mini-vidas and Konelab 20 analysers. RESULTS: Four patients developed post-operative complications (3 - UTIs with urinary retention, 1 - urosepsis. NGAL concentration increased significantly following FURS (p = 0.034). Although no significant changes were seen in Cystatin C, MPO and PCT (p ≥ 0.05) some key clinical observation were noted. Limiting factors for this study were the small number of patients recruited and restriction in blood sampling beyond 4 h. CONCLUSIONS: Although not confirmative, changes seen to biomarkers such as Cystatin C, NGAL and MPO in our observational clinical pilot-study may warrant further investigation, involving larger cohorts, to fully understand the role of these biomarkers and their potential association with post-operative complications which can develop following FURS.

RESUMO

OBJECTIVE: This study aimed to examine the association between team stress level and adverse tracheal intubation (TI)-associated events during neonatal intubations. STUDY DESIGN: TIs from 10 academic neonatal intensive care units were analyzed. Team stress level was rated immediately after TI using a 7-point Likert scale (1 = high stress). Associations among team stress, adverse TI-associated events, and TI characteristics were evaluated. RESULT: In this study, 208 of 2,009 TIs (10%) had high stress levels (score < 4). Oxygenation failure, hemodynamic instability, and family presence were associated with high stress level. Video laryngoscopy and premedication were associated with lower stress levels. High stress level TIs were associated with adverse TI-associated event rates (31 vs. 16%, p < 0.001), which remained significant after adjusting for potential confounders including patient, provider, and practice factors associated with high stress (odds ratio: 1.90, 96% confidence interval: 1.36-2.67, p < 0.001). CONCLUSION: High team stress levels during TI were more frequently reported among TIs with adverse events.

RESUMO

INTRODUCTION AND HYPOTHESIS: Laparoscopic repair of different female genitourinary fistulae has been recently reported, including both conventional and laparoendoscopic single-site surgery (LESS). We present our 10-year single-center experience of the laparoscopic repair of different types of female genitourinary fistulae. METHODS: A retrospective analysis of our records over the last 10 years was performed. Type of fistula, etiology, laparoscopic approach, operative data, postoperative outcome, and follow-up were recorded. RESULTS: Overall, 46 patients with laparoscopic repair of genitourinary fistulae were reported: 25 had vesicovaginal fistulae (VVF), 14 had vesicouterine fistulae (VUF), and 7 had ureterovaginal fistulae (UVF). Thirty-three patients had conventional laparoscopic repair, whereas 7 VVF and 6 VUF had LESS repair. In all patients with VVF and VUF, extravesical repair was carried out by excising the fistulous tract and closing both the bladder and the vagina or the uterus with interposing tissue in-between. In patients with UVF, extravesical ureteric re-implantation was performed. Mean operative time was 176 ± 25 min. Mean blood loss was 105 ± 25 cc. No intraoperative or postoperative complications occurred. None was converted to open surgery. Mean postoperative hospital stay was 3.2 ± 1.2 days. After a mean follow-up of 6.3 ± 3.1 years, all patients had undergone successful repair, except for one patient with complex VVF. CONCLUSIONS: Laparoscopic repair of VVF, VUF, and UVF is a feasible procedure with a high success rate and low morbidity. LESS repair of VVF and VUF has a comparable success rate to conventional laparoscopy, but with a shorter hospital stay and fewer analgesic requirements.

RESUMO

PURPOSE: This study examines the impact of postoperative noninvasive ventilation strategies on outcomes in esophageal atresia-tracheoesophageal fistula (EA-TEF) patients. METHODS: A single center retrospective chart review was conducted on all neonates followed at the EA-TEF Clinic from 2005 to 2017. Primary outcomes were: survival, anastomotic leak, stricture, pneumothorax, and mediastinitis. Statistical significance was determined using Chi-square and logistic regression (p ≤ .05). RESULTS: We reviewed 91 charts. Twenty-five infants (27.5%) were bridged with postextubation noninvasive ventilation (15 on Continuous Positive Airway Pressure (CPAP), 5 on Noninvasive Positive Pressure Ventilation (NIPPV), and 14 on High-Flow Nasal Cannula (HFNC)). Overall, 88 (96.7%) patients survived, 25 (35.7%) had a stricture, 14 (20%) had anastomotic leak, 9 (12.9%) had a pneumothorax, and 4 (5.7%) had mediastinitis. Use of NIPPV was associated with increased risk of mediastinitis (P = .005). Use of HFNC was associated with anastomotic leak (P = .009) and mediastinitis (P = .036). CONCLUSIONS: These data suggest that postoperative noninvasive ventilation techniques are associated with a significantly higher risk of anastomotic leak and mediastinitis. Further prospective research is needed to guide postoperative ventilation strategies in this population. TYPE OF STUDY: Retrospective study. LEVEL OF EVIDENCE: IV.

RESUMO

BACKGROUND: Neonatal tracheal intubation (NTI) is an important clinical skill. Suboptimal performance is associated with patient harm. Simulation training can improve NTI performance. Improving performance requires an objective assessment of competency. Competency assessment tools need strong evidence of validity. We hypothesized that an NTI competency assessment tool with multisource validity evidence could be developed and be used for formative and summative assessment during simulation-based training. METHODS: An NTI assessment tool was developed based on a literature review. The tool was refined through 2 rounds of a modified Delphi process involving 12 subject-matter experts. The final tool included a 22-item checklist, a global skills assessment, and an entrustable professional activity (EPA) level. The validity of the checklist was assessed by having 4 blinded reviewers score 23 videos of health care providers intubating a neonatal simulator. RESULTS: The checklist items had good internal consistency (overall α = 0.79). Checklist scores were greater for providers at greater training levels and with more NTI experience. Checklist scores correlated with global skills assessment (ρ = 0.85; P < .05), EPA levels (ρ = 0.87; P < .05), percent glottic exposure (r = 0.59; P < .05), and Cormack-Lehane scores (ρ = 0.95; P < .05). Checklist scores reliably predicted EPA levels. CONCLUSIONS: We developed an NTI competency assessment tool with multisource validity evidence. The tool was able to discriminate NTI performance based on experience. The tool can be used during simulation-based NTI training to provide formative and summative assessment and can aid with entrustment decisions.

RESUMO

Anterior cervical discectomy with fusion is a common surgical treatment that can relieve patients suffering from cervical spondylosis. This surgery is most commonly performed with the use of a cervical cage. One serious complication of the fusion cages commercially available in the market is subsidence of the cage with loss of the normal alignment of the spine and recurrent pain. This work presents the proof-of-concept of a fusion cage made of a graded porous titanium with microarchitecture minimizing the risk of subsidence associated with fully-solid implants. The optimized properties of the porous implant are obtained through a scheme combining multiscale mechanics and density-based topology optimization. Asymptotic homogenization is used to capture the effective properties of the porous material, which uses a tetrahedron based cell as building block. The stress levels and normal strains obtained under various loading conditions on the C7 superior surface of the vertebrae are used as indicators of subsidence. The results suggest a reduced risk of subsidence for the optimized implant versus the fully-solid implant. Under the most severe condition of combined loading, a collective improvement of the average von Mises stress up to 14% can be observed on the posterior, left, and right lateral regions of the C7 superior surface. Similarly, for the average normal strain, the optimized cage exhibits a more favourable distribution with a top gain of 21.7% at given locations.

RESUMO

AIM: To evaluate the effect of adding low dose trospium chloride with transcutaneous posterior tibial nerve stimulation (TPTNS) in the treatment of overactive bladder (OAB) in females after failure of behavioral therapy. METHODS: We randomized 30 women with OAB, in two groups: G I received 30 min TPTNS, three times a week; GII received TPTNS plus 20 mg trospium chloride daily. OAB Symptom Score questionnaire (OABSS), Incontinence Impact Questionnaire-short form 7 (IIQ-7), 3 day voiding diary and urodynamics at weeks 0 and 8 were evaluated. RESULTS: The groups were similar before treatment. Eight weeks after treatment, the mean OABSS decreased significantly to 8.53 ± 1.30 for group II vs 10.0 ± 2.0 for GI (P < 0.024). The mean IIQ-7 score decreased significantly to 51.86 ± 17.26 in group I vs 31.99 ± 9.26 in group II (P < 0.001). Before treatment, 11 (73.3%) and 4 (26.7%) patients in each group had moderate and poor quality of life (QoL), respectively. After treatment, 6 (40%) and 14 (93.3%) had good QoL, 7 (46.7%) and 1 (6.7%) had moderate QoL in GI and GII, respectively. Two (13.3%) patients in GI had poor QoL. The mean frequency was reduced to 8.60 ± 0.83 vs 10.60 ± 2.32 for GII and GI respectively (P = 0.006). The cystometric capacity increased from 263.40 ± 50.45 to 377.80 ± 112.92 mL (P = 0.001) for GII vs 250.13 ± 56.24 to 296.40 ± 99.0 mL (P = 0.026) for GI. CONCLUSION: TPTNS combined with low dose trospium chloride proved to be more effective than TPTNS alone in the treatment of OAB in females.

RESUMO

OBJECTIVE: To compare the safety and efficacy of bipolar vs monopolar transurethral resection of bladder tumour (TURBT) in patients maintained on low-dose aspirin with tumours >3 cm. PATIENTS AND METHODS: A prospective randomised single-centre study was performed including 200 patients with bladder tumours of >3 cm, as measured by ultrasonography. All patients were using low-dose aspirin (81 mg/day), which was not stopped in the perioperative period. Patients were randomised into two groups: Group A, monopolar TURBT (M-TURBT); Group B, bipolar TURBT (B-TURBT). The primary endpoint of the study was the decrease in postoperative haemoglobin (Hb) concentration measured using an automated cell counter. The secondary endpoints of the study were intraoperative blood transfusion or the occurrence of urethral trauma during cystoscopy and the need for re-coagulation. RESULTS: The postoperative reduction in Hb concentration, was significantly lower in the B-TURBT group [mean (SD) 0.55 (0.26) g/dL] compared with the M-TURBT group [mean (SD) 1.24 (0.61) g/dL] (P < 0.001). There was also a significant difference (in favour of B-TURBT) between the groups in the mean postoperative reduction in haematocrit and the mean postoperative hospital stay. There was no significant difference between the groups for the occurrence of obturator jerk, bladder perforation, and the need for blood transfusion. CONCLUSION: B-TURBT in patients maintained on low-dose aspirin is better than M-TURBT for minimising postoperative drop in Hb concentration.

RESUMO

OBJECTIVE: The aim of this study was to retrospectively review the experience and midterm results of laparoscopic pyeloplasty (LP) in patients with previous failed open pyeloplasty in comparison to primary LP. MATERIALS AND METHODS: Thirty-two patients who had undergone previous failed open surgery for management of ureteropelvic junction obstruction (UPJO) were reviewed. The patients underwent transperitoneal dismembered LP. All operations were performed by the same laparoscopist from March 2009 to June 2013. Surgical results were compared to 72 patients who underwent primary LP carried out by the same surgeon during the same period. RESULTS: The laparoscopic repyeloplasty group consisted of 14 men and 18 women. The mean age was 29 ± 6 years. The mean operative period was 133 ± 42 and 110 ± 57 min; the mean length of stay in hospital was 2.7 ± 2.3 and 1.3 ± 2.1 days; and the mean follow-up period was 32.4 ± 14 and 29.3 ± 11.2 months in the secondary and primary LP groups, respectively. The success rate was 90.6% for secondary LP and 94.4% for primary LP. There was no conversion in either group. The percentage of intraoperative and postoperative complications in secondary LP was 9.4% and 12.5%, respectively, compared with 0% and 5.6% in the primary LP group. CONCLUSIONS: Laparoscopic repyeloplasty is a safe and viable treatment option for secondary UPJO, with a success rate similar to that of primary repair but with longer operative time. Considerable experience in laparoscopic reconstructive procedures is a prerequisite for optimal results.

RESUMO

DNA repair mechanisms act as a warrior combating various damaging processes that ensue critical malignancies. DREMECELS was designed considering the malignancies with frequent alterations in DNA repair pathways, that is, colorectal and endometrial cancers, associated with Lynch syndrome (also known as HNPCC). Since lynch syndrome carries high risk (~40-60%) for both cancers, therefore we decided to cover all three diseases in this portal. Although a large population is presently affected by these malignancies, many resources are available for various cancer types but no database archives information on the genes specifically for only these cancers and disorders. The database contains 156 genes and two repair mechanisms, base excision repair (BER) and mismatch repair (MMR). Other parameters include some of the regulatory processes that have roles in these disease progressions due to incompetent repair mechanisms, specifically BER and MMR. However, our unique database mainly provides qualitative and quantitative information on these cancer types along with methylation, drug sensitivity, miRNAs, copy number variation (CNV) and somatic mutations data. This database would serve the scientific community by providing integrated information on these disease types, thus sustaining diagnostic and therapeutic processes. This repository would serve as an excellent accompaniment for researchers and biomedical professionals and facilitate in understanding such critical diseases. DREMECELS is publicly available at http://www.bioinfoindia.org/dremecels.
